Overview

PART I

We are a leading genome editing company focused on developing curative therapeutics utilizing a biological tool known as CRISPR/Cas9, which stands for
Clustered,  Regularly  Interspaced  Short  Palindromic  Repeats  (“CRISPR”)/CRISPR  associated  9  (“Cas9”).  This  is  a  technology  for  genome  editing,  the
process of altering selected sequences of genomic deoxyribonucleic acid (“DNA”). We believe that CRISPR/Cas9 technology has the potential to transform
medicine by editing disease-associated genes with a single treatment course, and that it can also be used to create novel engineered cell therapies that can
replace a patient’s diseased cells or effectively target various cancers and autoimmune diseases. We are leveraging our leading scientific expertise, clinical
development experience and intellectual property (“IP”) position to unlock a broad set of therapeutic applications for CRISPR/Cas9 genome editing and to
develop a potential new class of therapeutic products.

Our mission is to build a company to develop curative genome editing treatments that can positively transform the lives of people living with severe and life-
threatening disease. We believe we can deliver on our mission and provide long-term benefits for all of our stakeholders by focusing on four key elements -

•

•

•

•

Develop curative CRISPR/Cas9 based medicines;

Advance our science to help more patients;

Foster an environment that is the best place to make therapies; and

Focus on long-term sustainability.

Our strategy is to build a full-spectrum genome editing company, by leveraging our CRISPR/Cas9 platform across two areas: in vivo applications, in which
CRISPR/Cas9 is the therapy, delivered to target cells within the body; and ex vivo applications, in which CRISPR/Cas9 creates the therapy of engineered
human cells.

The breadth of our CRISPR/Cas9 platform and delivery technology allows us to pursue a multitude of therapeutic targets/clinical indications. Specifically, we
can target diseases that have the potential to be addressed by directly editing specific genes (i.e., gene knockout, repair, or insertion) as well as diseases that
may  be  targeted  by  genetically  engineered  cell  therapies.  The  successful  treatment  of  these  disorders  may  require  various  types  of  genome  edits,
CRISPR/Cas9 elements and DNA templates. We have assembled multiple in vivo and engineered cell therapy capabilities into a pipeline that reflects our full-
spectrum approach and leverages the modularity inherent in our platform.

Our diversified pipeline includes in vivo development programs targeting genetic diseases, including transthyretin amyloidosis (“ATTR”), which we are co-
developing  with  Regeneron  Pharmaceuticals,  Inc.  (“Regeneron”),  and  hereditary  angioedema  (“HAE”).  Our  pipeline  also  includes  ex  vivo  programs
consisting of two separate efforts: (1) a set of proprietary programs focused on engineered cell therapies to treat various cancers and autoimmune diseases
including  our  lead  ex  vivo  program  to  target  Wilms’  Tumor  1  (“WT1”)  for  acute  myeloid  leukemia  (“AML”);  and  (2)  partnered  programs  developed  in
collaboration  with  Novartis  Institutes  for  BioMedical  Research,  Inc.  (“Novartis”),  focused  on  chimeric  antigen  receptor  (“CAR”)  T  (“CAR-T”)  cells,
hematopoietic stem cells (“HSCs”), the stem cells from which all of the various types of blood cells originate, and stem cells in the eye, or ocular stem cells
(“OSCs”).

CRISPR/Cas9 Technology

CRISPR/Cas9 genome editing technology was derived from an adaptive defense mechanism of bacteria. In 2012, Dr. Jennifer Doudna, one of our scientific
co-founders, and her colleagues published a paper in the journal Science describing the use of CRISPR/Cas9 as a genome editing tool. Genome editing is the
precise and targeted modification of the genetic material of cells or viruses. The Cas9 endonuclease, a key component of CRISPR/Cas9, can be programmed
to  cut  double-stranded  DNA  at  specific  locations.  A  ribonucleic  acid  (“RNA”)  molecule,  called  a  guide  RNA  (“gRNA”),  binds  to  Cas9  and  can  be
programmed to direct the Cas9 enzyme to a specific DNA sequence.

5

 
 
 
 
 
The CRISPR/Cas9 system offers a revolutionary approach for therapeutic development due to its broad potential to precisely edit the genome. This system
can be used to make three general types of edits: knockouts, repairs and insertions. Each of these editing strategies takes advantage of naturally-occurring
biological mechanisms to effect the desired genetic alteration. Products based on CRISPR/Cas9 technology may be one of two types: products where CRISPR
itself  constitutes  the  therapy  and  the  edit  occurs  in vivo,  and  products  where  CRISPR  is  used  to  create  the  therapy  where  the  edit  occurs  ex vivo.  In  vivo
editing has the potential to provide curative therapeutic options for patients with genetically-based diseases, while ex vivo editing has the potential to create
cell-based therapies to combat cancer or autoimmune diseases.

Strategy

Our  goal  is  to  build  a  full  spectrum,  fully  integrated,  product-driven  biotechnology  company,  focused  on  developing  and  commercializing  curative
CRISPR/Cas9-based therapeutics. Our approach to advancing the broad potential of genome editing includes plans to:

Focus on Indications that Enable Us to Fully Develop the Potential of the CRISPR/Cas9 System. To maximize our opportunity to rapidly develop clinically
successful products, we have applied a risk-mitigated approach to selecting indications with significant unmet medical needs based on four primary criteria:

•

•

•

•

the type of edit: knockout, repair or insertion;

the delivery modality for in vivo and ex vivo applications;

the existence of efficient regulatory pathways to approval; and

the potential for the CRISPR/Cas9 system to provide therapeutic benefits when compared to existing therapeutic options.

We believe these selection criteria position us to build a diversified pipeline, in which we are not reliant on any single delivery technology or editing approach
for  success.  In  addition,  we  believe  we  can  apply  the  learnings  from  our  current  programs  to  inform  our  selection  of  additional  indications  and  targets  of
interest. We are also exploring ways to identify potential new therapeutic targets suitable for modulation with the CRISPR/Cas9 technology. We believe this
approach  serves  to  increase  the  probabilities  of  success  in  our  initial  indications,  generate  insights  that  will  accelerate  the  development  of  additional
therapeutic products and broaden the opportunity for potential strategic alliances.

Aggressively Pursue In Vivo  Liver  Indications  to  Develop  Therapeutics  Rapidly  with  Our  Proprietary  Delivery  System.  For  our  in vivo  indications,  we
selected  well-validated  targets  in  diseases  with  significant  unmet  medical  needs  where  there  are  predictive  biomarkers,  or  measurable  indicators  of  a
biological  condition  or  state,  with  strong  disease  correlation  and  where  the  CRISPR/Cas9  technology  and  delivery  tools  existing  today  could  be  applied
towards developing a novel therapeutic. Our current in vivo pipeline opportunities target diseases of the liver, including ATTR and HAE, which we believe we
can address using our proprietary lipid nanoparticle (“LNP”) delivery system.

Actively Develop and Expand Ex Vivo Therapeutic Programs. We  are  independently  researching  and  developing  proprietary  engineered  cell  therapies  to
treat various cancers and autoimmune diseases, for example using T cell receptor (“TCR”)-engineered T cells for immuno-oncology applications, engineered
regulatory T cells for autoimmune disorders and other cell types such as engineered induced pluripotent stem cells for these potential applications. Further, we
are supporting Novartis’ development of CAR-T cell, HSC and OSC therapies.

Continue to Leverage Strategic Partnerships to Accelerate Clinical Development. We view strategic partnerships as important drivers for accelerating the
achievement of our goal of rapidly developing curative therapies. The potential application of CRISPR/Cas9 is extremely broad, and we plan to continue to
identify partners who can contribute meaningful resources and insights to our programs and allow us to more rapidly bring scientific innovation to a broader
patient population. Our collaboration focusing on HSCs, OSCs and CAR-T cells with Novartis, an industry leader with the first commercially available CAR-
T cell product, our ongoing partnership on in vivo liver  indications  with  Regeneron,  a  leader  in  genetics-driven  drug  discovery  and  development,  and  our
research collaboration on engineered T cell therapies with IRCCS Ospedale San Raffaele (“OSR”), Milan, a leading European research-university hospital,
exemplify this strategy.

6

 
 
 
 
 
Grow Our Leadership Position in the Field of Genome Editing. We are committed to broadening our capabilities to remain at the cutting edge of genome
editing research. We will continue to invest internally in developing our platform capabilities, including innovative delivery modalities, technologies and tools
to advance our therapeutic programs. We will also continue to explore accessing external technologies or opportunities to enhance our leadership position in
developing innovative therapeutics.

Our Pipeline

Our diversified pipeline includes in vivo and ex vivo programs. Our in vivo programs focus on treating patients that have significant unmet medical needs due
to diseases attributable to genes expressed in the liver – ATTR (which we are co-developing with Regeneron) and HAE. Delivery plays a key role in our in
vivo  therapeutic  approach.  We  have  shown  in  animal  models  that  our  proprietary  LNP  delivery  technology,  which  encapsulates  the  therapeutic  Cas9
messenger RNA (“mRNA”) and gRNA into LNPs, can systemically deliver these therapeutic components to the liver.

For ex vivo applications, our wholly owned programs focus on next-generation, engineered cell therapy solutions that utilize antigen specific TCRs. The cells
to be modified ex vivo  can  come  from  the  individual  patient  (autologous  source)  or  from  another  individual  (allogeneic  source).  Our  goal  for  the  ex vivo
pipeline is to move from autologous to allogeneic therapies, and from liquid to solid tumors.

We believe our full spectrum approach to in vivo and ex vivo programs positions us to build a pipeline across a wide range of indications.

The following table summarizes the status of our most advanced programs:

In Vivo Programs

Our selection criteria include identifying diseases that originate in the liver; have well-defined mutations that can be addressed by a single knockout, repair or
insertion approach; have readily measurable therapeutic endpoints with observable clinical responses; and for which effective treatments are absent, limited or
unduly burdensome. Our initial in vivo indications target genetic liver diseases, including ATTR and HAE. Our current efforts on in vivo delivery focus on the
use of LNPs for delivery of the CRISPR/Cas9 complex to the liver.

Transthyretin Amyloidosis (“ATTR”) Program

Background

ATTR is a progressive and fatal disorder resulting from deposition of insoluble amyloid fibrils into multiple organs and tissues leading to systemic failure.
Blood-borne transthyretin (“TTR”) protein is produced by hepatocytes and normally circulates as a soluble homotetramer that facilitates transport of vitamin
A,  via  retinol  binding  protein,  as  well  as  the  thyroid  hormone,  thyroxine.  Mutations  in  the  TTR  gene  lead  to  the  production  of  TTR  proteins  that  are
destabilized  in  their  tetramer  form.  These  tetramers  more  readily  dissociate  into  the  monomeric  form,  and  thence  to  an  aggregative  form  that  results  in
amyloid deposits in tissues. These deposits cause damage in those tissues, resulting in a disorder known as hereditary TTR amyloidosis (“hATTR”). Over 120
different genetic mutations are currently known to cause hATTR.

Deposits of TTR amyloid in the heart, nerves and/or other tissues can lead to diverse disease manifestations, including two main hereditary forms – hATTR
with polyneuropathy (“hATTR-PN”), and hATTR with cardiomyopathy (“hATTR-CM”). Typical onset of disease symptoms is during adulthood and can be
fatal within 2 to 15 years. Estimates suggest that approximately 50,000 patients suffer from hATTR worldwide.

In addition to the hereditary forms described above, ATTR can also develop spontaneously in the absence of any TTR gene mutation. This wild-type ATTR
(“wtATTR”),  is  increasingly  being  recognized  as  a  significant  and  often  undiagnosed  cause  of  heart  failure  in  the  elderly  and  is  the  subject  of  active
investigation. Recent estimates suggest that, globally, between 200,000 and 500,000 people may suffer from wtATTR with cardiomyopathy (“wtATTR-CM”).

Limitations of Current Treatment Options

Currently, there are two therapies for the treatment of hATTR-PN approved in the United States (“U.S.”), and three approved in most major markets outside
of  the  U.S.  While  these  therapies  have  shown  the  potential  to  slow  or  halt  the  progression  of  neuropathic  symptoms,  and  in  some  patients  lead  to  an
improvement in symptoms, their approved prescribing instructions require them to be administered chronically for the life of the patient in order to sustain
benefit. Additionally, patient response to these therapies varies. While some patients may experience symptomatic improvement after being treated with these
therapies,  the  disease  continues  to  progress  in  many  of  the  treated  patients,  which  highlights  the  continued  need  for  efficacious  and  potentially  curative
therapies.  At  present,  there  is  only  one  therapy  approved  for  ATTR-CM  (including  both  hATTR-CM  and  wtATTR-CM)  which  has  shown  the  ability  to
improve patient outcomes, though most patients still appear to have the progressive disease. As with the treatments for hATTR-PN, chronic, lifetime dosing is
required to sustain the therapeutic effects.

Our Approach

We believe that we can apply CRISPR/Cas9 technology to potentially cure ATTR by employing a knockout edit to disable the TTR  gene  in  the  liver.  We
expect this approach to greatly reduce the production of circulating TTR protein levels, which should slow or stop the accumulation of undesired TTR protein
in the nerves and the heart, thereby halting disease progression. Using this approach, we aim to address both forms of the disease - hATTR and wtATTR.
Current  treatments  and  ongoing  clinical  trials  in  hATTR-PN  have  shown  a  significant  correlation  between  TTR  protein  reduction  and  clinical  benefit.
Additionally, these studies suggest that loss of TTR gene expression from the liver would be well-tolerated in adult humans. We believe our approach may
improve patient outcomes by potentially eliminating defective TTR protein in a single dose, as opposed to life-long therapy. We have assessed delivery of
gRNAs  directed  at  the  TTR  gene  together  with  Cas9  mRNA  via  LNPs  and  have  achieved  high  levels  of  liver  cell  editing  in  vitro  and in  vivo  as  well  as
reduction of serum TTR protein in multiple non-human species.

In non-human primate (“NHP”) studies, we have demonstrated our ability to reduce circulating TTR protein to estimated therapeutically relevant levels after
a single systemic administration of LNPs containing our CRISPR/Cas9 complex. In December 2019, we completed a year-long durability study of our lead
LNP formulation, maintaining an average reduction of more than 95% of serum TTR protein after a single dose in NHPs. The data from our various NHP
studies has also demonstrated the transient nature of Intellia’s proprietary modular LNP delivery system, which was rapidly cleared from circulation, with all
CRISPR/Cas9 complex undetectable in blood and liver within ten days of administration.

8

 
 
On  August  1,  2019,  we  announced  that  we  conducted  our pre-Investigational New  Drug  (“IND”)  meeting  with  the  U.S.  Food  and  Drug  Administration
(“FDA”) and  initiated  IND-enabling  toxicology  studies. In  addition,  we  expect  to  submit  an  IND  application  for  NTLA-2001,  our  lead  candidate  for  the
treatment of ATTR, in mid-2020 and anticipate dosing the first patients in the second half of 2020. On February 27, 2020, we announced that we remain on
track to submit an IND application for NTLA-2001 in mid-2020 and anticipate dosing the first patients in the second half of 2020.

Clinical Development Pathway

Our first in-human studies in ATTR are expected to take place in patients with ATTR who have started to exhibit symptoms related to amyloid deposition.
The primary objective of these studies will be to show that the therapy can be delivered safely to the patient. A secondary objective will be to identify early
indicators of efficacy, which may include reductions in TTR protein levels in blood. We expect that the results of our preclinical studies, and discussions with
the FDA, the European Medicines Agency (“EMA”) and other relevant regulatory agencies as well as patient advocacy groups will be important to inform
our  clinical  trial  design.  Pursuant  to  our  collaboration  agreement  with  Regeneron,  we  and  Regeneron  entered  into  a  Co-Development  and  Co-Promotion
(“Co/Co”) agreement directed to the first collaboration target, TTR (the “ATTR Co/Co”) agreement, under which the parties share development costs and
worldwide  commercial  profits,  and  for  which  we  are  the  clinical  and  commercial  lead.  Pursuant  to  the  ATTR  Co/Co  agreement,  Regeneron  funded
approximately  50%  of  the  program’s  development  costs  through  2019.  Starting  June  2020  and  thereafter,  Regeneron  will  share  approximately  25%  of
worldwide  development  costs  and  commercial  profits  for  the  ATTR  program.  For  more  information  regarding  our  collaboration  with  Regeneron,  see  the
section below entitled “Collaborations - Regeneron Pharmaceuticals, Inc.”

Hereditary Angioedema (“HAE”) Program

Background

HAE  is  a  rare  genetic  disorder  characterized  by  recurrent,  painful  and  unpredictable  episodes  of  severe  swelling.  The  most  common  areas  of  the  body  to
develop  swelling  are  the  limbs,  face,  intestinal  tract  and  airway.  Minor  trauma  or  stress  may  trigger  an  attack  but  swelling  often  occurs  without  a  known
trigger. Episodes involving the intestinal tract cause severe abdominal pain, nausea and vomiting. Swelling in the airway can restrict breathing and lead to
life-threatening obstruction of the airway. The disease is caused by increased levels of bradykinin, a protein which leads to swelling. Most patients with HAE
have a deficiency of C1 esterase inhibitor (“C1-INH”) protein, which normally prevents the unregulated release and buildup of bradykinin. HAE is estimated
to affect 1 in 50,000 people, with an estimated 11,000 to 21,500 diagnosed HAE patients in the U.S. and Europe.

Limitations of Current Treatment Options

Currently there are multiple therapies approved to treat HAE, including acute and prophylactic approaches. Acute treatments are used to treat patients who are
experiencing an attack. Prophylactic treatments are used to reduce the number of attacks that a patient may experience. Prophylactic treatments have proven
to be effective in reducing the number of attacks for most patients, though some patients still experience breakthrough attacks and such treatment options
require regular injections which can be associated with significant treatment burden and impact on quality of life.

Our Approach

Using our modular LNP delivery system, we aim to knock out the kallikrein B1 (“KLKB1”) gene with a single course of treatment to reduce the spontaneous
activation  of  biological  pathways  responsible  for  generating  bradykinin  and  thereby  ameliorate  the  frequency  and  intensity  of  HAE  attacks.  We  believe
KLKB1 knockout to be safe, as humans with prekallikrein deficiency appear to have no known health effects. In addition, inhibition of kallikrein activity has
proven to be a clinically effective approach as a prophylactic treatment for HAE.

In February 2020, we shared data demonstrating that the knockout of KLKB1 produced in NHPs resulted in a 90% reduction in kallikrein activity following a
single dose. The reduction of kallikrein activity observed corresponds to the reduced enzymatic levels in patients that meaningfully impact HAE attack rates
(Source: Banerji et al., NEJM, 2017). This kallikrein activity reduction was sustained for at least five months in an ongoing study, in a highly reproducible
manner observed across both rodent and NHP studies. We expect to nominate a development candidate for the treatment of HAE in the first half of 2020.

Pursuant to our collaboration agreement with Regeneron and prior to the initiation of IND-enabling studies, Regeneron could opt into a Co/Co  agreement
directed to our HAE program. If Regeneron opted to enter into such an agreement,  the  parties  would  share  development  costs  and  worldwide  commercial
profits, and we would be the clinical and commercial lead. For more information regarding our collaboration with Regeneron, see the section below entitled
“Collaborations - Regeneron Pharmaceuticals, Inc.”

Ex Vivo Programs

We are independently researching and developing proprietary engineered cell therapies to treat various oncological and autoimmune diseases, for example
TCR-engineered  T  cells  for  immuno-oncology  applications  and  engineered  regulatory  T  cells  for  autoimmune  disorders.  Our  diverse  product  strategy
includes multiple elements. In particular:

•

•

•

We  are  exploring  non-CAR-T  cellular  approaches  that  use  immune  cells,  including  T  cells  expressing  recombinant  TCRs,  for  oncology
indications. For example, in our existing collaboration with OSR, we have identified optimized TCRs recognizing a tumor target, WT1, that
could be used to treat a variety of cancers.

We seek to develop allogeneic cellular therapies, which are those derived from unmatched donors and modified outside of the human body to
allow them to be administered to an unrelated patient.

We are also exploring methods to apply CRISPR/Cas9 editing to CD4 immune cells to induce a non-reverting regulatory T cell phenotype, to
create therapies that address autoimmune diseases.

In addition, our partner Novartis is developing therapies using CAR-T cells for oncology indications, as well as HSC and OSC-based therapies.

Acute Myeloid Leukemia (“AML”)

Background

AML includes a heterogenous group of blood cancers arising from the malignant expansion of hematopoietic cells of the myeloid lineage. AML is associated
with weakness, fatigue and bleeding resulting from the depletion of healthy myeloid cells, and is typically rapidly progressive and fatal without immediate
treatment. AML is an aggressive and hard-to-treat cancer, resulting in less than 30% of patients living more than five years after diagnosis. AML is the most
common acute leukemia in adults and is associated with the largest number of annual deaths from leukemia in the U.S. It is estimated that there have been
nearly 11,000 deaths due to AML, as well as over 21,000 new AML cases in the U.S. in 2019. While AML can occur at any age, the prevalence of the disease
increases with age, resulting in a median age at diagnosis of 67 years.

Limitations of Current Treatment Options

Induction chemotherapy, most commonly with cytarabine and anthracycline, represents the standard first-line treatment option for patients who can tolerate
an  intensive  treatment  regimen.  Patients  who  achieve  remission  with  induction  typically  receive  additional  chemotherapy  or  an  HSC  transplant  as
consolidation therapy. While this treatment approach has the potential to lead to sustained remission or even cure patients, the intensity of these treatments is
associated with significant morbidity and mortality. Patients who are older, who represent a significant proportion of the patient population, are often unable
to be treated with an intensive regimen and are commonly treated with lower intensity chemotherapy or hypomethylating agents. While these therapies offer
the potential to prolong survival and address some of the clinical symptomatology associated with AML, they are not generally considered to be potentially
curative treatments. Even among patients who are considered fit enough to receive an intensive regimen, a significant proportion of patients are refractory
(i.e.,  do  not  achieve  a  complete  remission).  Further,  relapse  is  common  even  among  those  patients  who  achieve  a  remission.  While  additional  lines  of
treatment may be possible, cure rates are extremely low among relapsed and refractory patients. Combined, the high percentage of patients who are unable to
tolerate an intensive potentially-curative regimen, the high percentage of refractory patients and high relapse rates have led to the low overall survival rate in
AML patients.

10

 
 
 
 
Over the past several years, new treatments have emerged for AML with different mechanisms of action. While these treatments have led to improvements in
response rates and in some cases increased overall survival, the outcomes demonstrated thus far have been incremental in nature and long-term outcomes in
AML continue to be extremely poor.

Our Approach

We have nominated NTLA-5001 as our first engineered T cell therapy development candidate for the treatment of AML, utilizing our TCR-directed approach
to  target  the  WT1  intracellular  antigen.  Our  WT1-directed  TCR  T-cell  therapy  aims  to  develop  a  broadly  applicable  treatment  for  AML,  regardless  of
mutational  background  of  a  patient’s  leukemia.  This  approach  employs  CRISPR/Cas9  complexes  to  knock  out  and  replace  the  endogenous  TCR  with  a
natural, high affinity therapeutic TCR. The resulting cells are engineered to be capable of specific and potent killing of AML blasts without bone marrow cell
toxicity.  In  February  2020,  we  presented  data  demonstrating  that  the  selection  of  a  natural,  high-affinity  TCR,  in  combination  with  our  CRISPR-enabled
engineering  and  targeted  insertion,  results  in  an  engineered  T  cell  capable  of  specific  and  potent  killing  of  primary  AML  blasts.  Importantly,  our  studies
showed that CRISPR-enabled engineering overcomes key challenges of traditional TCR approaches, such as mispairing between therapeutic and endogenous
TCR, therefore creating a more homogenous T cell product. The cells engineered with our lead WT1 TCR also exhibited no detectable off-target reactivity to
bone marrow cells, which express WT1 at low levels. We continue to advance good manufacturing practices (“GMP”) manufacturing-related development
activities in support of a Phase I clinical trial. We expect to submit an IND application for the use of NTLA-5001 to treat AML in the first half of 2021.

Research Collaboration with Novartis

Under our collaboration agreement with Novartis, we received an upfront technology access payment from Novartis of $10.0 million, and we have received
an additional $50.0 million, in aggregate, in additional technology access fees and research payments during the five-year collaboration term. In December
2019, the research term ended, although the 2014 Novartis Agreement remains in effect. Accordingly, Novartis has selected various CAR-T cell, HSC and
OSC targets for continued development, for which we will be eligible to receive milestone and royalty payments in the future. Further, we are eligible to earn
up to $230.3 million in development, regulatory and sales-based milestone payments and mid-single-digit royalties, in each case, on a per-product basis for
the  products  developed  by  Novartis,  subject  to  certain  target-based  limitations.  For  more  information  regarding  our  collaboration  with  Novartis,  see  the
section below entitled “Collaborations - Novartis Institutes for BioMedical Research, Inc.”

CAR-T Cell Program

In 2017, the first CAR-T cell products, including Novartis’ Kymriah, were approved by the FDA to treat certain oncological indications such as pediatric
acute lymphoblastic leukemia and Non-Hodgkins Lymphoma. Additional therapies are being developed for blood cancers such as AML, multiple myeloma
and chronic lymphocytic leukemia, as well as several solid-tumor cancers. In CAR-T cell therapy, naturally-occurring immune cells, specifically T cells, are
modified ex vivo by inserting a CAR into the T cells, thereby redirecting their response towards cancer cells.

CAR-T cell products can benefit from the application of CRISPR/Cas9 in multiple ways, including:

•

•

•

•

CRISPR/Cas9  could  be  used  to  create  a  universal  donor  CAR-T  cell  by  knocking  out  cell  surface  markers  that  cause  a  patient’s  immune
system  to  recognize  another  person’s  cells  as  foreign.  Allowing  multiple  patients  to  be  treated  using  cells  from  a  single  donor  could
significantly streamline manufacturing and make CAR-T cell therapy more widely accessible.

CRISPR/Cas9 could be used to modify the T cells to enhance their survival or activity against cancer cells.

CRISPR/Cas9 could be used to introduce the CAR into a precise location in the genome with a specific integrated copy number, as opposed
to the current method involving semi-random integration, thus potentially improving the safety profile of the resulting cells.

CRISPR/Cas9 could be used to knock out one or more of the proteins believed to be responsible for certain serious side effects that can result
in dangerously high fevers or severe loss of blood pressure.

11

 
 
 
 
 
Novartis  is  progressing  CRISPR/Cas9-edited  CAR-T  cells  directed  to  its  selected  CAR  targets.  The  target  selection  process  was  completed  by  the  end  of
2019, and all non-selected CAR targets are available for our development.

HSC Program

HSCs are the stem cells from which all of the various types of blood cells originate. The HSCs present in transplanted bone marrow, mobilized peripheral
blood or cord blood can repopulate a patient’s blood system. There are multiple potential opportunities for treating patients using engineered HSCs, including
treating three common classes of blood-related disorders, such as hemoglobin disorders, including sickle cell disease and beta thalassemia; primary immune
deficiencies, such as X-linked severe combined immunodeficiency; and bone marrow failures, such as Fanconi anemia. There are limited treatment options
available for these types of blood disorders, and available options typically require chronic blood transfusions or bone marrow transplants. These procedures
are  associated  with  significant  risk,  including  mortality.  We  believe  the  CRISPR/Cas9  system  can  be  used  to  potentially  provide  curative  benefits  by
correcting  the  underlying  genetic  defect  in  blood  cells  of  patients  with  these  disorders.  In  additional  applications,  normal  HSCs  may  be  engineered  ex
vivo using CRISPR/Cas9 to express a therapeutic protein, which is then administered to patients in need of that protein. In 2019, Novartis completed IND-
enabling studies in support of a potential IND on a program targeting sickle cell disease that leveraged our CRISPR/Cas 9 technology. We are entitled to
receive a $5.0 million payment related to this regulatory milestone upon filing the IND. During the research collaboration with Novartis that concluded in
December 2019, we pursued a number of potential gene targets and therapeutic indications with Novartis. From those targets, Novartis has selected a limited
number of HSC targets for development into human therapeutics. Novartis’ ability to select additional HSC therapeutic targets under the agreement expired in
December 2019.

OSC Program

In 2018 we announced an expansion of our existing cell therapy collaboration with Novartis to include the ex vivo development of innovative cell therapies
using certain OSCs. As part of the updated collaboration terms, Novartis obtained the right to develop CRISPR/Cas9-based products for a limited number of
targets  using  these  stem  cells.  We  received  a  one-time  $10.0  million  cash  payment  and,  consistent  with  the  original  collaboration  agreement,  we  are  also
eligible  to  receive  downstream  success-based  milestones  and  royalties. We  retained  rights  to  all  other  in vivo  and  ex  vivo  applications  of  CRISPR/Cas9,
including for eye disorders. Novartis’ selection period for additional OSC targets expired in December 2019.

Other Research Programs

We are pursuing a number of in vivo and ex vivo genome editing programs. Within our in vivo research efforts, we continue to work on programs such as
primary hyperoxaluria Type 1 (“PH1”), alpha-1 antitrypsin deficiency (“AATD”), and Hemophilia B, which leverage our capabilities to knockout, insert and
make consecutive edits to the genome. We are also investigating delivery strategies that target tissues outside of the liver.

Within  our  ex  vivo  research  efforts,  we  are  developing  engineered  cell  therapies  to  treat  a  range  of  hematological  and  solid  tumors.  We  are  pursuing
modalities, such as TCR, with broad potential in multiple indications. We continue to advance efforts to move from autologous to allogeneic therapies and
from liquid to solid tumors.

Our Platform

An integral part of creating a full-spectrum therapeutic product pipeline based on CRISPR/Cas9 technology is to develop a robust technology platform, based
on proprietary and in-licensed technologies. Our modular platform is based on our proprietary components that can serve both in vivo and ex vivo programs,
as well as our delivery technologies that can be used in either program type. In addition to the components described below, we are developing robust, high
volume  (high  throughput)  capabilities  centering  around  enabling  strategic  target  identification  and  validation  that  we  believe  will  provide  us  with  a
competitive advantage in creating successful therapeutic products.

12

 
Informatics

We have built a high throughput, scalable data processing and analysis, or informatics, infrastructure to support various aspects of our platform, including
gRNA selection and evaluation of on- and off-target editing in cells. Depending on the desired editing strategy, we use proprietary bioinformatics methods to
design candidate guides and select those that we believe are both highly specific and have high cutting efficiency. As we grow our experimental data set, we
continue to incorporate gRNA performance into our algorithms to improve their predictive power.

Guide RNA qualification

As part of the process to identify gRNAs for potential development candidates, we screen numerous gRNAs for their ability to generate the required edit at
the genomic site of interest, called on-target activity, as well as any potential propensity to generate unwanted events at other sites in the genome, also known
as off-target activity. To evaluate on-target activity, we use high throughput sequencing methods to analyze the genomes of edited cells, allowing us to assess
overall editing efficiency and to examine the nature of the editing events, such as specific insertions or deletions.

For  gRNAs  selected  through  our  primary  on-target  screens,  we  perform  a  variety  of  analyses  to  look  for  possible  off-target  editing  events,  including
bioinformatic  predictions  and  experimental  methods.  Part  of  our  approach  involves  identifying  candidates  with  no  or  few  off-target  sites  based  on
experimental measurements of genome-wide DNA breaks, as well as targeted sequencing of such candidate sites to evaluate actual off-target editing events in
relevant  cell  types.  We  continue  to  optimize  our  gRNA  qualification  capability  over  time  by  increasing  our  throughput,  improving  our  off-target  activity
detection accuracy and increasing our bioinformatics predictive accuracy.

Guide RNA format

CRISPR/Cas9  systems  can  function  with  gRNAs  having  a  variety  of  modifications,  such  as  changes  to  the  gRNA  sequence  or  chemical  modifications  of
nucleotides.  As  part  of  our  development  of  CRISPR/Cas9  therapeutics,  we  are  engineering  modified  gRNAs  to,  for  example,  improve  editing  efficiency,
specificity and stability inside cells, as well as to reduce the likelihood of an immune response. We believe our work in this area will allow us to develop the
most appropriate gRNAs for therapeutic applications.

Nuclease

Our current preferred Cas9 protein is derived from a species of bacteria called S. pyogenes (“Spy”), which is the Cas9 used in the vast majority of published
CRISPR/Cas9 literature to date. As part of the therapeutic development process, we are adapting and engineering Spy Cas9 with the goal of improving its
specificity, activity and manufacturability. In addition, we are exploring other naturally occurring Cas9 proteins and nucleases from other bacteria, which may
differ from Spy Cas9 in aspects such as specificity, size or mechanism of DNA recognition, binding and cutting. We are pursuing these alternative Cas9 forms
and other nucleases through ongoing internal work, collaborations with our existing partners and scientific founders and in-licensing opportunities. We also
are investigating targeted modifications of Cas9 that can modulate DNA activity by mechanisms other than cleavage. We believe that different therapeutic
applications may be best addressed using different forms of Cas9 or other nucleases, depending on the target cell or tissue of interest, the delivery method and
the desired type of edit.

Cas9 Edit Type

Knockout

The  CRISPR/Cas9  system,  by  itself,  primarily  functions  to  cut  DNA,  while  the  resulting  desired  therapeutic  editing  events  are  performed  by  the  cell,
subsequent to the cut, as the cell seeks to rejoin the cut ends. One type of edit is caused by a DNA repair mechanism that is prone to losing or adding short
lengths  of  DNA  around  the  cut  site.  The  resulting  changes  in  the  DNA  impair  the  function  of  any  encoded  protein,  causing  a  knockout  edit.  Using  a
combination of our informatics, gRNA qualification and format and nuclease platform capabilities, we have developed an efficient process to identify gRNAs
that create this kind of edit at high frequency while possessing high specificity for the on-target site and no substantial off-target effects.

13

 
Within both NHP and rodent disease models we have demonstrated the ability to knockout multiple targets in the liver including TTR, KLKB1, SERPINA1,
hydroxyacid oxidase 1 (“Hao1”) and lactate dehydrogenase A (“Ldha”). These data demonstrated the modular nature of our propriety LNP delivery system.

Gene Insertion

While  knockout  edits  can  be  made  using  solely  a  Cas9  protein  and  gRNA,  other  kinds  of  editing,  involving  repair  and  insertion,  additionally  require  a
template DNA that contains a desired genomic sequence that may be inserted or used to correct the original sequence. For ex vivo applications, in addition to
delivering  a  Cas9-gRNA  complex,  the  DNA  template  may  be  delivered  by  physical  means  such  as  electroporation  in  combination  with  a  Cas9-gRNA
complex, or by other means such as viral vectors or chemical means. For in vivo applications, we have developed combination approaches for delivering the
editing machinery by LNP, and the repair and insertion templates by adeno-associated virus (“AAV”) vectors. For example, at the 2019 American Society of
Gene and Cell Therapy Annual Meeting, we presented initial data from an ongoing study demonstrating the first CRISPR/Cas9-mediated, targeted transgene
insertion  in  the  liver  of  NHPs,  using  F9  as  a  model  gene.  In  August  2019,  we  announced  additional  results  from  the  in-life  portion  of  the  NHP  study.
Following a single dose to NHPs of the hybrid LNP-AAV delivery system containing an F9 DNA template, we demonstrated that the circulating human FIX
protein  levels  achieved  in  NHPs  were  at  or  above  normal  levels.  Additionally,  the  NHP  data  expands  on  the  durability  of  clinically  relevant  human  FIX
protein  levels  achieved  in  mice  for  over  12  months.  We  are  currently  working  closely  with  Regeneron  to  move  the  program  forward  and  are  also
independently evaluating the hybrid LNP-AAV delivery system for targeted insertion across several other transgenes of interest in an in vivo setting.

Consecutive Editing

Consecutive editing is any combination of knockout and insertion strategies. At the 2019 European Society of Gene and Cell Therapy Annual Meeting, we
reported the first demonstration of a consecutive in vivo gene knockout and insertion in a mouse model of AATD. The consecutive edits led to a greater than
98% reduction of the disease-causing protein and sustained restoration of the missing protein to therapeutically relevant circulating protein levels throughout
the study.

In Vivo Delivery

We are focusing our initial in vivo applications in the liver, where we deliver the CRISPR/Cas9 therapy to patients using our proprietary LNP platform.

LNPs encapsulate the therapeutic cargo, providing it with stability, selective delivery, improved pharmacologic properties and controlled circulation time. Our
therapeutic cargo is designed to degrade relatively quickly, resulting in transient expression of Cas9. We see multiple advantages of using LNPs as an in vivo
delivery  vehicle,  particularly  as  optimized  by  us  for  delivery  of  the  CRISPR/Cas9  system  or  its  components.  First,  certain  LNPs  have  historically
demonstrated efficacy, safety and favorable tolerability and are currently used as a delivery system for mRNA, as well as small interfering RNA (“siRNA”).
mRNA is RNA that encodes proteins and siRNA is RNA that causes the degradation of selected cellular mRNAs. Additionally, LNPs are chemically well-
defined  and  have  a  completely  synthetic  route  of  manufacture,  which  permits  greater  scalability.  We  are  currently  advancing  our  programs  using  our
proprietary LNP delivery system, which uses a set of biodegradable, well-tolerated lipids, based on lipids originally developed by Novartis and in-licensed by
us for use with all genome editing technologies, including CRISPR/Cas9 products. To date, we have successfully demonstrated well-tolerated in vivo editing
in various animal models, including in mouse, rat and NHP livers, with a single dose of systemically delivered LNPs. We also have shown successful delivery
to cells in the brains of mice and NHPs and editing in mouse brain cells using CRISPR/Cas9 delivered by direct injection of one of our proprietary LNP
formulations.

14

 
With our team’s expertise in LNP delivery technology, we expect to be able to translate the LNPs that we are using for our preclinical evaluation to clinical
development in humans. In addition, we are exploring options for incorporating Cas9 into therapeutic products in multiple formats. For example, Cas9 can be
delivered in its protein form or could be delivered as a nucleic acid, such as an mRNA. For delivery of Cas9 mRNA, we have identified, and continue to
investigate, modifications that may improve expression and stability, as well as reduce the potential for an immune response. We plan to continue to further
improve  on  our  LNP  system  for  a  variety  of  CRISPR/Cas9  therapeutic  components,  including  templates  for  repair  and  insertion  edits.  In  parallel,  we  are
exploring additional delivery vehicles, including synthetic particles and viral vectors. We also are developing delivery strategies that we believe will allow us
to target other tissues.

Ex Vivo Delivery

Cellular  therapies  are  based  on  the  administration  of  engineered  human  cells  that  are  modified  to  provide  or  restore  necessary  functions  in  the  cells  of
patients, or to target and eliminate cells with harmful attributes, such as cancer cells. The cells to be modified ex vivo can come from the individual patient
(autologous  source)  or  from  another  individual  (allogeneic  source).  We  use  the  CRISPR/Cas9  system  to  perform  the  modification,  and  deliver  the  system
using a clinically proven method, electroporation. In human cells, we have been able to achieve robustly high editing efficiency, including rates greater than
90%,  of  both  copies  of  a  single  gene  (bi-allelic  editing),  while  preserving  cell  viability.  In  parallel,  we  are  exploring  other  delivery  methods  for
ex vivo introduction of biological material to cells, which may provide advantages such as delivery efficiency.

We have also simultaneously targeted multiple genes in an ex vivo setting and achieved high bi-allelic editing rates for both genes, demonstrating what we
believe to be therapeutically relevant editing of multiple genes simultaneously (multiplex editing). The ability to achieve multiplex editing may be critical in
targeting certain diseases.

Collaborations

To  accelerate  the  development  and  commercialization  of  CRISPR/Cas9-based  products  in  multiple  therapeutic  areas,  we  have  formed,  and  intend  to  seek
other opportunities to form, strategic alliances with collaborators who can augment our leadership in CRISPR/Cas9 therapeutic development.

Novartis Institutes for BioMedical Research, Inc. (“Novartis”)

In December 2014, we entered into a strategic license and collaboration agreement with Novartis (the “2014 Novartis Agreement”), primarily focused on the
research  of  new  ex  vivo  CRISPR/Cas9-edited  therapies  using  CAR-T  cells  and  HSCs.  The  agreement  was  amended  in  December  2018  to  also  include
research  on  OSCs.    In  December  2019,  per  the  terms  of  the  2014  Novartis  Agreement,  the  research  term  ended,  although  the  2014  Novartis  Agreement
remains in effect. As provided in the agreement, Novartis has selected various CAR-T cell, HSC and OSC targets for continued development, for which we
will be eligible to receive milestone and royalty payments in the future.

Agreement Structure. Under the 2014 Novartis Agreement, the parties agreed to engage in collaborative research activities using our CRISPR/Cas9 platform
to identify and research therapeutic, prophylactic and palliative products and services relating to the following applications: (a) ex vivo HSCs and (b) ex vivo
CAR-T cells. In addition, in the last two years of the collaboration term, Novartis was permitted to engage in research and development of a limited number
of in vivo targets using our platform.

Scope of Collaboration. During the five-year research term, the parties researched potential therapeutic, prophylactic and palliative ex vivo applications  of
CRISPR/Cas9 technology in HSCs and CAR-T cells. Research expenses incurred by us in support of the collaboration were reimbursed by Novartis.

15

 
HSC Program. We and Novartis agreed to collaborate exclusively with each other during the research term to conduct research on ex vivo  applications  of
CRISPR/Cas9  technology  for  HSC  targets  under  a  research  plan  agreed  upon  by  both  parties.  At  the  end  of  the  research  term  in  December  2019,  this
exclusive HSC research collaboration ended. Within the ex vivo HSC therapeutic space, Novartis obtained exclusive rights to research and develop human
therapeutics for a limited number of HSC targets, which Novartis selected in a series of selection windows. During the research term, we had the right to
choose a limited number of HSC targets for our exclusive development and commercialization per the specified selection schedule. Following these selections
by Novartis and us, Novartis had the right to research an additional limited number of non-selected HSC targets on a non-exclusive basis, but Novartis did not
exercise  this  right.  Because  the  research  term  has  ended,  the  parties  can  no  longer  select  additional  exclusive  HSC  targets,  and  Novartis  has  an  exclusive
license  to  research,  develop  and  commercialize  human therapeutic  products  directed  to  its  selected  HSC  targets.  Novartis  assumed  sole  responsibility  for
developing and commercializing human therapeutic products for the HSC targets it selected arising from our collaboration and is solely responsible for the
costs  and  expenses  of  developing,  manufacturing  and  commercializing  its  HSC  products.  To  maintain  its  exclusive  license  on  a  target-by-target  basis,
Novartis is required to use commercially reasonable efforts to research, develop and commercialize at least one HSC product directed to each of their selected
HSC targets. In 2019, Novartis announced that it had completed IND-enabling studies in support of a potential IND on a program targeting sickle cell disease
that leveraged our CRISPR/Cas 9 technology.

CAR-T  Program.  We  and  Novartis  also  agreed  to  collaborate  exclusively  with  each  other  during  the  research  term  on  research  directed  to  applying
CRISPR/Cas9 technology to CAR-T cell targets under a research plan agreed upon by both parties. At the end of the research term in December 2019, this
exclusive research collaboration ended. Under the 2014 Novartis Agreement, Novartis assumed sole responsibility for developing human therapeutic products
for  the  limited  number  of  CAR  targets  it  selected  arising  from  our  collaboration  and  is  solely  responsible  for  the  costs  and  expenses  of  developing,
manufacturing and commercializing its selected targets. Novartis has an exclusive license to research, develop and commercialize CAR products directed to
its selected CAR-T cell targets. To maintain its exclusive license on a target-by-target basis, Novartis is required to use commercially reasonable efforts to
research, develop and commercialize at least one CAR-T cell product directed to each of its selected CAR targets.

Governance.  The  parties  formed  HSC  and  CAR-T  cell  steering  committees  with  responsibility  for  oversight  of  these  respective  research  programs  and
approval of the associated research plans. Beginning in December 2018, the HSC steering committee also became responsible for the OSC program (see the
section below entitled “2018 Amendment to the Agreement”). These steering committees in turn were overseen by a joint steering committee and comprised
an equal number of representatives from each party. The steering committees terminated upon completion of the research term in December 2019.

Financial  Terms.  We  received  an  upfront  technology  access  payment  from  Novartis  of  $10.0  million  in  January  2015  and  were  entitled  to  additional
technology access fees of $20.0 million and quarterly research payments of $1.0 million, or up to $20.0 million in the aggregate, during the five-year research
term. To date, we have received $20.0 million in technology access fees and $20.0 million in research payments related to these programs. In addition, for
each Novartis product under the collaboration (whether it is an HSC or CAR-T cell product, and beginning in December 2018, an OSC product), subject to
certain conditions, we may be eligible to receive (i) up to $30.3 million in development milestones, including for the filing of an IND application and for the
dosing of the first patient in each of Phase IIa, Phase IIb and Phase III clinical trials, (ii) up to $50.0 million in regulatory milestones for the product’s first
indication, including regulatory approvals in the U.S. and European Union (“EU”), (iii) up to $50.0 million in regulatory milestones for the product’s second
indication, if any, including U.S. and EU regulatory approvals, (iv) royalties on net sales in the mid-single digits, and (v) net sales milestone payments of up
to $100.0 million. In 2019, Novartis completed IND-enabling studies in support of a potential IND on a program targeting sickle cell disease leveraging our
CRISPR/Cas 9 technology for which we are entitled to a $5.0 million milestone payment upon filing of the IND.

Equity Investments. Additionally, at the inception of the arrangement at which time Intellia was a privately-held company, Novartis invested $9.0 million to
purchase our Class A-1 and Class A-2 Preferred Units (the “Preferred Units”). The difference between the cash proceeds received from Novartis for the units
and the $11.6 million estimated fair value of those units at the date of issuance was determined to be $2.6 million. Accordingly, $2.6 million of the upfront
technology access payment was allocated to record the Preferred Units purchased by Novartis at fair value.

16

 
License  Grant  to  Novartis.  In  the  2014  Novartis  Agreement,  we  granted  to  Novartis  a  license  to  our  CRISPR/Cas9  platform  technology,  including  a
sublicense to certain platform rights licensed from Caribou Biosciences, Inc. (“Caribou”), that is exclusive in the ex vivo HSC, CAR-T cell and in vivo fields
with respect to each target selected by Novartis pursuant to the agreement and the research plan as long as Novartis continues to use commercially reasonable
efforts to research, develop, and commercialize CRISPR-edited products directed to such targets.

License Grant to Intellia. In the 2014 Novartis Agreement, prior to the Novartis Amendment described below, Novartis granted us a non-exclusive license to
its  IP  covering  a  small  molecule  for  HSC  expansion  and  its  LNP  platform  technology  to  research,  develop  and  commercialize  HSC  and  in  vivo  genome
editing products, respectively.

Intellectual  Property.  IP  that  we  develop  within  the  collaboration  related  to  our  CRISPR/Cas9  platform  will  be  owned  solely  by  us,  while  all  other  IP
developed within the collaboration, including IP covering products arising from the collaboration, will be jointly owned by us and Novartis.

2018 Amendment to the Agreement. In December 2018, we entered into an amendment to this agreement with Novartis (the “Novartis Amendment”) which
expanded the scope of the 2014 Novartis Agreement to include the ex vivo development of CRISPR/Cas9-based cell therapies using limbal stem cells, a type
of OSC, primarily against gene targets selected by Novartis. In connection with the Novartis Amendment, we received a one-time payment of $10.0 million in
December 2018. The governance, license rights and development responsibilities, as well as milestones and royalties, associated with any OSC program and
product follow those for the HSC programs and products. Because the research term has ended, as with the HSC programs, the parties’ exclusive research
collaboration  for  limbal  stem  cells  has  ended,  and  Novartis  has  an  exclusive  license  to  research,  develop  and  commercialize  OSC  products  directed  to  a
limited  number  of  OSC  targets.  As  part  of  the  Novartis  Amendment,  Intellia’s  license  to  Novartis’  LNP  technology  was  expanded  to  include  use  in  all
genome editing applications in both in vivo and ex vivo settings.

Term  and  Termination.  The  term  of  the  2014  Novartis  Agreement  expires  on  the  later  of  (i)  the  expiration  of  Novartis’  payment  obligations  under  the
agreement and (ii) the date of expiration of the last-to-expire of the patent rights licensed to us or Novartis under the agreement. Novartis’ royalty payment
obligations  expire  on  a  country-by-country  and  product-by-product  basis  upon  the  later  of  (i)  the  expiration  of  the  last  valid  claim  of  the  royalty-bearing
patents  covering  such  product  in  such  country  or  (ii)  ten  years  after  the  first  commercial  sale  of  such  product  in  such  country.  We  may  terminate  the
agreement if Novartis or its affiliates institute a patent challenge against our IP rights, and all improvements thereto, licensed to Novartis under the agreement.
Novartis may terminate the agreement, without cause, upon 90 days’ written notice to us subject to certain conditions and continuing obligations. Either party
may terminate the agreement in the event of the other party’s uncured material breach or bankruptcy - or insolvency-related events.

Regeneron Pharmaceuticals, Inc. (“Regeneron”)

In April 2016, we entered into a license and collaboration agreement with Regeneron (the “Regeneron Agreement”).

Agreement Structure. The Regeneron Agreement has two principal components: (i) a product development component under which the parties will research,
develop  and  commercialize  CRISPR/Cas-based  therapeutic  products  primarily  focused  on  genome  editing  in  the  liver,  and  (ii)  a  technology  collaboration
component, pursuant to which the parties will engage in research and development activities aimed at discovering and developing novel technologies and
improvements  to  CRISPR/Cas  technology  to  enhance  our  genome  editing  platform.  Under  the  Regeneron  Agreement,  we  also  may  access  the  Regeneron
Genetics Center and proprietary mouse models to be provided by Regeneron for a limited number of our liver programs.

Scope of Collaboration. Under the terms of the six-year research collaboration, Regeneron may obtain exclusive rights for up to ten targets to be chosen by
Regeneron during the collaboration term subject to a target selection process and various adjustments and limitations set forth in the agreement. Of these ten
total  targets,  Regeneron  may  select  up  to  five  non-liver  targets,  while  the  remaining  targets  must  be  focused  in  the  liver.  Certain  non-liver  targets  from
Intellia's ongoing and planned research at the time, as well as any targets included in another Intellia collaboration, were excluded from this collaboration. At
the inception of the agreement, Regeneron selected the first of its ten targets, ATTR, which is subject to a Co/Co agreement between us and Regeneron, the
general terms and conditions for which were outlined within the Regeneron Agreement.

17

 
Research Collaboration. Research activities under the collaboration will be governed by evaluation and research and development plans that will outline the
parties’ responsibilities under, anticipated timelines of and budgets for, the various programs. We will assist Regeneron with the preliminary evaluation of its
selected liver targets, and Regeneron will be responsible for preclinical research and conducting clinical development, manufacturing and commercialization
of products directed to each of its exclusive targets. We may assist, as requested by Regeneron, with the later discovery and research of product candidates
directed to any selected target. For each selected target, Regeneron is required to use commercially reasonable efforts to submit regulatory filings necessary to
achieve IND acceptance for at least one product directed to each applicable target, and following IND acceptance for at least one product, to develop and
commercialize such product.

Reserved Liver Targets. We retain the exclusive right to solely develop products via CRISPR/Cas genome editing directed against certain specified genetic
targets. During the collaboration term and subject to a target selection process, we have the right to choose additional liver targets for our own development
using commercially reasonable efforts. Certain targets that either we or Regeneron select during the term may be subject to further Co/Co agreements at our
or Regeneron’s option, as applicable, which either can exercise pursuant to defined conditions.

Governance.  Under  the  Regeneron  Agreement,  the  parties  formed  a  joint  steering  committee,  which  is  responsible  for  setting  research  objectives  and
overseeing the general strategies and research and development activities undertaken by the parties. Additionally, under the ATTR Co/Co, the parties formed
a Joint Development and Commercialization Committee (“JDCC”) to oversee all profit share products under the Co/Co agreement as discussed below. The
JDCC has responsibility for overseeing the development, manufacture, regulatory matters and commercialization (including pricing and reimbursement) of
ATTR, as the first profit share product under the Regeneron Agreement.

Financial  Terms.  We  received  a  nonrefundable  upfront  payment  of  $75.0  million.  In  addition,  on  Regeneron  programs  that  are  not  subject  to  Co/Co
agreements we may be eligible to earn, on a per-licensed target basis, (i) up to $25.0 million in development milestones, including for the dosing of the first
patient in each of Phase I, Phase II and Phase III clinical trials; (ii) up to $110.0 million in regulatory milestones, including for the acceptance of a regulatory
filing  in  the  U.S.,  and  for  obtaining  regulatory  approval  in  the  U.S.  and  in  certain  other  identified  countries;  and  (iii)  up  to  $185.0  million  in  sales-based
milestone  payments.  We  are  also  eligible  to  earn  royalties  ranging  from  the  high  single  digits  to  low  teens,  in  each  case,  on  a  per-product  basis,  which
royalties  are  potentially  subject  to  various  reductions  and  offsets  and  incorporate  our  existing  low-  to  mid-single-digit  royalty  obligations  under  a  license
agreement with Caribou.

Equity Investments. In  connection  with  this  collaboration,  Regeneron  purchased  $50.0  million  of  our  common  stock  in  a  private  placement  under  a  Stock
Purchase Agreement concurrent with our initial public offering.

Term and Termination. The research collaboration term ends in April 2022, except that Regeneron may make a one-time payment of $25.0 million to extend
the  term  for  an  additional  two-year  period.  The  Regeneron  Agreement  will  continue  until  the  date  when  no  royalty  or  other  payment  obligations  are  due,
unless  earlier  terminated  in  accordance  with  the  terms  of  the  agreement.  Regeneron’s  royalty  payment  obligations  expire  on  a  country-by-country  and
product-by-product basis upon the later of (i) the expiration of the last valid claim of the royalty-bearing patents covering such product in such country, (ii) 12
years from the first commercial sale of such product in such country, or (iii) the expiration of regulatory exclusivity for such product. We may terminate the
Regeneron Agreement on a target-by-target basis if Regeneron or any of its affiliates institutes a patent challenge against our CRISPR/Cas or certain other
background patent rights or does not proceed with the development of a product directed to a selected target within specified periods of time. Regeneron may
terminate the agreement, without cause, upon 180 days written notice to us, either in its entirety or on a target-by-target basis, in which event, certain rights in
the terminated targets and associated IP revert to us, as described in the agreement. Following such termination, we may owe Regeneron royalties, in certain
circumstances, up to mid-single digits on any terminated targets that we subsequently commercialize on a product-by-product basis for a period of 12 years
after the first commercial sale of any such products. Either party may terminate the Regeneron Agreement either in its entirety or with respect to the research
collaboration or one or more of the targets selected by Regeneron, in the event of the other party’s uncured material breach.

18

 
Co-Development and Co-Promotion Agreement. In July 2018, we and Regeneron finalized the form of the Co/Co agreement that will be used as the basis for
each Co/Co agreement directed to a target. Simultaneously, we and Regeneron executed the Co/Co agreement directed to the first collaboration target, ATTR,
for which we are the clinical and commercial Lead Party (see below) and Regeneron is the Participating Party (see below).

Co-Development and Co-Promotion: Agreement Structure. Under the Regeneron Agreement, Regeneron has the right to exercise up to at least five options to
enter into a Co/Co agreement for our liver targets (other than Intellia’s reserved liver targets), while we may exercise at least one option to enter into a Co/Co
agreement for Regeneron’s liver targets, the exact number of options being subject to certain conditions of the target selection process. Each option to enter
into a Co/Co agreement must be exercised (or forfeited) once a target reaches a defined preclinical stage. Within 15 days of exercising the option, the party
exercising the option must pay $1.5 million to the other party as compensation for prior work. The ATTR program was exempted from this payment. One
party will be the “Lead Party” and the other party the “Participating Party”. The Lead Party shall have control and primary responsibility for the development,
manufacturing, regulatory and commercial activities. The Participating Party shall have the right to consult on these activities through its participation on the
JDCC  and  will  have  the  right  to  co-fund  development  and  commercialization  activities  in  exchange  for  a  share  of  profits.  In  general,  under  each  Co/Co
agreement,  the  parties  will  share  equally  in  worldwide  development  costs  and  profits  of  any  future  products.  Prior  to  reaching  a  specific  development
milestone, the Participating Party may elect to reduce its share of worldwide development costs and profits by 50%.

Pursuant to the ATTR Co/Co, Regeneron was obligated to fund 50% of the research and development costs for the ATTR program. On December 13, 2019,
Regeneron informed us that it would exercise its rights under the ATTR Co/Co to modify its share of worldwide development costs and commercial profits
for the ATTR program from 50% to 25%, effective six months after its notice.

Co-Development  and  Co-Promotion:  Termination.  Either  party  may  terminate  by  providing  180  days  written  notice.  If  Intellia  terminates,  the  product
becomes  a  Regeneron  product,  and  is  subject  to  all  future  milestone  and  royalty  payment  obligations  under  the  Regeneron  Agreement.  If  Regeneron
terminates and has contributed at least $5.0 million in development costs under the Co/Co agreement, Intellia will pay low- to mid-single digit royalties on the
net sales of the product, depending on co-funding percentage, stage at termination and, if any, incorporation of Regeneron’s IP into the product.

IRCCS Ospedale San Raffaele (“OSR”), Milan

In  June  2017,  we  entered  into  a  collaboration  and  license  option  agreement  with  Ospedale  San  Raffaele,  Milan  (the  “OSR  Agreement”).  The  research
collaboration  between  the  parties  involves  identifying  new  WT1  TCRs,  editing  T  cells  with  CRISPR/Cas9  to  knockout  the  endogenous  TCR  and  insert  a
WT1 TCR, and testing the engineered T cells to assess their ability to attack tumors, particularly AML and solid tumors, that express WT1. Generally, OSR is
responsible for identifying, characterizing and testing new WT1-specific TCRs, and we are responsible for developing and providing CRISPR/Cas9 reagents,
methods  and  other  technologies  for  editing  T  cells.  We  have  the  exclusive  right  to  use  the  IP  developed  under  the  collaboration  to  develop  therapeutic
products. Discoveries from this collaboration are included in our first ex vivo  product  candidate  directed  to  AML,  which  we  refer  to  as  NTLA-5001.  The
parties  are  researching  additional  engineered  WT1  TCR  T  cells  as  therapies  for  other  types  of  cancer,  including  those  caused  by  solid  tumors.  The  OSR
Agreement  also  granted  us  an  option  to  obtain  an  exclusive  license  to  certain  patent  families  of  OSR  and  IP  developed  in  the  collaboration  to  research,
develop and commercialize engineered WT1 TCR T cells comprising the WT1 TCRs identified by OSR in the collaboration. In December 2019, we exercised
this option.

We will also owe OSR a royalty below 1% on net sales of licensed products sold by us and a share in the low- to mid-single digit percentage of  sublicense
revenue that we receive if we sublicense our rights under the OSR Agreement to a third party. The research collaboration ends in June 2020, except that it
may  be  extended  by  the  parties.  The  OSR  Agreement  will  continue  until  the  date  when  no  royalty  or  other  payment  obligations  are  due,  unless  earlier
terminated in accordance with the terms of the agreement.

Potential Future Collaborations

We view strategic partnerships as important drivers for helping accelerate our goal of rapidly treating patients. The potential application of CRISPR/Cas9 is
extremely broad, and we plan to continue to identify partners who can contribute meaningful resources and insights to our programs and allow us to more
rapidly bring scientific innovation to a broader patient population.

Intellectual Property

We believe we are well positioned in terms of our IP because we:

•

•

•

have  built,  and  intend  to  expand,  a  broad  worldwide  portfolio  of  IP,  including  patents  and  patent  applications,  in  areas  relevant  to  the
development and commercialization of human therapeutic products using CRISPR/Cas9 technology;

protect our IP by maintaining trade secrets relating to our proprietary technology innovations and know-how; and

intend  to  take  additional  steps,  where  appropriate,  to  further  protect  our  IP  rights,  including,  for  example,  through  the  use  of  copyright
protection, trademark and regulatory protections available via orphan drug designations, data exclusivity, market exclusivity and patent term
extensions.

Our licensed patent portfolio encompasses foundational filings on the use of CRISPR/Cas9 systems for genome editing, improvement modifications of these
CRISPR systems, LNP technologies, TCRs for specific targets, and cell expansion technology relevant to stem cell-based therapies. We access these patent
estates from licensors including Caribou, Novartis and OSR. We also actively apply for, maintain, and plan to defend and enforce, as needed, our internally
developed and externally licensed patent rights. Furthermore, we continue to search for and evaluate opportunities to in-license IP relevant to our targeted
therapeutic programs and platforms and to develop and acquire new IP in collaboration with third parties.

In addition to our in-licensed IP, our IP portfolio includes over 30 patent families filed since 2015 covering solely or jointly owned technologies that we have
developed independently or through our collaborations with Novartis, Regeneron and OSR. The patent families claim inventions relating to CRISPR/Cas9
improvements,  methods  for  delivering  CRISPR/Cas9  complexes,  methods  of  treating  diseases  using  CRISPR/Cas9  genome  editing,  and  methods  for
analyzing editing events, among others. Patents resulting from our internal portfolio, if issued, would expire no earlier than 2036.

We actively apply for, maintain, and plan to defend and enforce, as needed, our internally developed and externally licensed patent rights. Furthermore, we
continue to search for and evaluate opportunities to in-license IP relevant to our targeted therapeutic programs and platforms and to develop and acquire new
IP in collaboration with third parties.

Caribou Biosciences In-Licensed Intellectual Property (“Caribou”)

In  July  2014,  we  entered  into  a  license  agreement  with  Caribou  (the  “Caribou  License”),  as  subsequently  amended  and  supplemented,  for  an  exclusive,
worldwide license for human therapeutic, prophylactic, and palliative uses, except for anti-fungal and anti-microbial uses, defined in the license agreement as
our  field  of  use,  of  any  CRISPR/Cas9-related  patents  and  applications  owned,  controlled  or  licensed  by  Caribou  as  well  as  companion  diagnostics  to  our
product or product candidates. The license agreement also included exclusive rights in our field of use to any CRISPR/Cas9-related IP developed by Caribou
after July 16, 2014 and through a cut-off date of January 30, 2018. The agreement further includes a non-exclusive research license to conduct research and
development  on  product  candidates  and  products.  The  Caribou  licensed  patent  portfolio  includes  several  U.S.  and  foreign  patents  and  patent  applications
owned by Caribou, and U.S. and foreign patents and patent applications co-owned by the Regents of the University of California, the University of Vienna
and  Dr.  Emmanuelle  Charpentier,  as  well  as  U.S.  and  foreign  patents  and  patent  applications  owned  or  controlled  by  Pioneer  Hi-Bred  International
(“Pioneer”) and its affiliates. We have the right to grant sublicenses to the Caribou licensed patent portfolio to third parties in our field of use. Caribou retains
the right to practice the licensed IP in all other fields, including for its own specific therapeutics purposes, provided it does not pertain to the application of
CRISPR/Cas9 technology to the development of products in our field of use.

20

 
 
 
 
Pursuant to a services agreement entered into with Caribou in parallel with the license agreement, we also received two years of research and development
services from Caribou, which ended in November 2016. Any IP developed under the services agreement is owned by Caribou and is included in, and subject
to the terms of, our license agreement with Caribou.

In relation to our founding, we issued Caribou 8,110,599 shares of our junior preferred stock. We paid Caribou $5.0 million over the term of the two-year
services agreement; and have agreed to pay 30.0% of Caribou’s patent prosecution, filing and maintenance costs for the IP included in the license agreement
amounting to a total of $4.3 million paid through December 31, 2019. We also granted Caribou an exclusive, royalty-free, worldwide license, with the right to
sublicense, to any CRISPR/Cas9 patents, patent applications and know-how in Caribou’s retained fields of use owned or developed by us between July 16,
2014 and January 30, 2018. Caribou, which is obligated to pay a portion of our patent filing, prosecution and maintenance costs for any such licensed IP, also
has an option to sublicense any CRISPR/Cas9 IP in-licensed by us for uses and activities in its retained field of use.

The Caribou License grants us sublicenses in our field of use to IP in-licensed by Caribou from the Regents of the University of California and the University
of Vienna. Further, under the license agreement, we had an option to sublicense for our field of use any new IP in-licensed by Caribou through January 30,
2018. In July 2015, we exercised our option to sublicense a portfolio in-licensed by Caribou from Pioneer, according to the terms described below.

The term of the Caribou License is until the expiration of the last-to-expire patent right that is licensed to either party. We must use commercially reasonable
and diligent efforts to research, develop, manufacture and commercialize at least one product. Either party may terminate the agreement in the event of the
other  party’s  uncured  material  breach,  bankruptcy  or  insolvency-related  events,  or  breach  of  its  obligations  with  respect  to  the  included  in-licenses.  The
license agreement with Caribou also gives us access, in our field of use, to Caribou internally developed IP. Since March 2013 and through the IP cutoff date,
Caribou  filed  over  50  patent  applications  in  the  U.S.  and  internationally,  which  relate  to  the  CRISPR/Cas  platform,  including  modified  and  improved
CRISPR/Cas9 systems or components, and methods of use that are part of our license. We cannot ensure that these applications will lead to issued claims that
cover our products or activities. Any patents that grant from these applications will expire in or after 2034, assuming payment of necessary maintenance fees.

On  October  17,  2018,  we  initiated  an  arbitration  proceeding  against  Caribou  asserting  that  Caribou  is  violating  the  terms  and  conditions  of  the  Caribou
License,  as  well  as  other  contractual  and  legal  rights,  by  using  and  seeking  to  license  to  third  parties  two  patent  families  relating  to  specific  structural  or
chemical  modifications  of  gRNAs,  that  were  purportedly  invented  or  controlled  by  Caribou,  in  our  exclusive  human  therapeutic  field.  Under  the  Caribou
License, Caribou granted to us a worldwide, exclusive license to all of Caribou’s IP relating to CRISPR/Cas9 technology for all therapeutic, prophylactic and
palliative uses and applications for any or all diseases and conditions in humans, with the sole exceptions of anti-microbial and/or anti-fungal applications.
The license encompassed all CRISPR/Cas9 IP developed or controlled by Caribou as of July 16, 2014 and through January 30, 2018 that was necessary or
useful for us to develop, manufacture or commercialize products in our field, as well as any technology developed by Caribou under a service agreement
entered into by us and Caribou in July 2014. Caribou has asserted that the two families of IP are outside the scope of our license. In accordance with the
Caribou  License,  we  submitted  a  demand  for  arbitration  seeking  a  declaration  that  the  disputed  IP  is  included  within  the  scope  of  our  license  under  the
Caribou License, an award of compensatory, consequential and punitive damages based on Caribou’s conduct, and an injunction prohibiting Caribou from
licensing or using this IP in our exclusive human therapeutics field, among other claims.

On  September  26,  2019,  we  announced  that  the  arbitration  panel  issued  an  interim  award  concluding  that  both  the  structural  and  chemical  gRNAs
modification  technologies  were  exclusively  licensed  to  us  by  Caribou  pursuant  to  the  Caribou  License.  After  concluding  that  the  chemical  modification
technology was within the scope of our exclusive license from Caribou, the arbitration panel nevertheless noted that its decision could delay or otherwise
adversely impact the development of these modified gRNAs as human therapeutics. It also noted that we currently are not using these modified gRNAs in any
of  our  active  programs.  Thus,  solely  with  respect  to  the  particular  modified  gRNAs,  the  arbitration  panel  stated  that  it  will  declare  that  Caribou  has  an
equitable “leaseback”, which it described as exclusive, perpetual and worldwide (the “Caribou Award”). The panel instructed the parties to negotiate the terms
of the Caribou Award, including Caribou’s future payments to us for the same, but the parties’ negotiations reached an impasse.

21

 
On February 6, 2020, after considering additional submissions from the parties, the panel clarified that the Caribou Award is limited to a particular on-going
Caribou program, which seeks to develop a CAR-T cell product directed at CD19. The panel instructed the parties to seek to negotiate terms based on this
scope. Accordingly, the Caribou Award will be subject to terms, including Caribou’s future payments to us to be negotiated by the parties or, if unsuccessful,
adjudicated in additional arbitration or judicial proceedings.

Pursuant  to  the  September  2019  interim  award,  the  Caribou  Award  by  the  panel  does  not  include  the  structural  guide  modifications  IP  at  issue  in  the
arbitration,  any  other  IP  exclusively  licensed  or  sublicensed  by  Caribou  to  us  under  the  Caribou  License  (including  but  not  limited  to  the  foundational
CRISPR/Cas9 IP co-owned by the Regents of the University of California, University of Vienna and Dr. Emmanuelle Charpentier), or any other of our IP.

Upon, and subject to the terms of, a final award, which will follow further arbitration or legal proceedings and potential additional negotiations between the
parties, Caribou could be able to use the modified gRNAs at issue for CAR-T cell human therapeutics directed at CD19. Either we or Caribou may challenge
the arbitration panel’s decisions under limited circumstances.

Other than with regards to the technologies in dispute, the interim award has no effect on our rights or Caribou’s obligations under the Caribou License. The
interim award has no impact on any of our current programs, although it could impact the 2014 Novartis Agreement.

The Regents of the University of California and the University of Vienna Intellectual Property

The Regents of the University of California and the University of Vienna (collectively, “UC/Vienna”) co-own with Dr. Emmanuelle Charpentier a worldwide
patent portfolio, which covers methods of use and compositions relating to engineered CRISPR/Cas9 systems for, among other things, cleaving or editing
DNA  and  altering  gene  product  expression  in  various  organisms,  including  humans.  We  refer  to  this  co-owned  worldwide  patent  portfolio  as  the
UC/Vienna/Charpentier patent family. The earliest claimed priority date for this patent family is May 25, 2012. As of December 31, 2019, this family includes
granted  patents  in  many  jurisdictions  outside  the  U.S.,  including  for  example  the  United  Kingdom,  Germany,  Australia,  China  and  the  approximately  40
countries that are members of the European Patent Convention. Corresponding applications are being prosecuted in the United States Patent and Trademark
Office (“USPTO”) and other patent agencies across the world. Any patents that ultimately issue from this family and are appropriately maintained will expire
in or after 2033.

Caribou entered into an exclusive, worldwide license in all fields, with the right to sublicense, for this patent family with UC/Vienna in April 2013 solely
under  UC/Vienna  ownership  rights.  Caribou’s  license  remains  in  effect  for  the  life  of  the  last-to-expire  patent  or  last-to-be-abandoned  patent  application
licensed,  whichever  is  later.  Through  our  license  agreement  with  Caribou,  we  have  an  exclusive  sublicense  to  UC/Vienna’s  interest  in  this  foundational
CRISPR/Cas9 patent family for use in human therapeutics, except for anti-fungal and anti-microbial uses as defined in the license agreement as our field of
use. For products covered by this license and their companion diagnostics, we will owe mid-single-digit royalties on net sales. In addition, we may be subject
to milestone payments of $0.1 million upon the first filing of an IND application, a total of $0.5 million for Phase II and Phase III clinical trials, $0.5 million
to $1.0 million for each of the first three approved new drug applications or biologics license applications in the U.S., and $0.2 million for each of the first
three approved indications in Europe. Caribou has the right to terminate its agreement with UC/Vienna at any time or the agreement may be terminated due to
an uncured material breach. We cannot guarantee that Caribou will maintain the UC/Vienna license for its full term. Should the license between Caribou and
UC/Vienna  be  terminated  for  any  reason,  any  compliant  Caribou  sublicenses  as  of  the  termination  date  will  remain  in  effect  and  will  be  assigned  to
UC/Vienna in place of Caribou. Specifically, if we are in compliance with our obligations under our sublicense and Caribou and UC/Vienna terminate their
agreement, UC/Vienna would replace Caribou as our licensor.

22

 
On April 13, 2015, UC/Vienna/Charpentier jointly filed a request with the USPTO asking that an interference be declared between a UC/Vienna/Charpentier
patent  application  and  certain  patents  issued  to  the  Broad  Institute,  Massachusetts  Institute  of  Technology,  and  the  President  and  Fellows  of  Harvard  College
(collectively, the “Broad Institute patent family” or the “Broad”), which claim aspects of CRISPR/Cas9 systems and methods to edit genes in eukaryotic cells,
including human cells. An interference is an adversarial proceeding conducted by the USPTO’s Patent Trial and Appeal Board (the “PTAB”) to determine the
initial inventor of a particular invention claimed in U.S. patents and patent applications owned by different parties. On January 11, 2016, the PTAB declared an
interference involving one UC/Vienna/Charpentier application, 12 Broad issued patents and a Broad patent application. In the order declaring the interference, the
PTAB designated UC/Vienna/Charpentier the “Senior Party” and the Broad the “Junior Party”. In March 2016, the PTAB re-declared the interference to add an
additional U.S. patent application owned by the Broad.  On February 15, 2017, the PTAB dismissed the proceeding finding that the parties’ respective patent
claims  involved  in  the  interference  were  distinct  such  that  they  did  not  meet  the  legal  requirement  to  proceed  with  the  interference.  Specifically,  the  PTAB
concluded  that  the  Broad’s  claims  were  directed  to  the  use  of  CRISPR/Cas9  only  in  eukaryotic  cells  and,  thus  were  patently  distinct  from
UC/Vienna/Charpentier’s claims, which were directed to the use of CRISPR/Cas9 in all settings. As a result of this proceeding’s dismissal, the PTAB did not
make a decision regarding which party actually first invented the use of CRISPR/Cas9 systems and methods to edit genes in eukaryotic cells. In April 2017,
UC/Vienna/Charpentier  appealed  to  the  U.S.  Court  of  Appeals  for  the  Federal  Circuit  (“the  Federal  Circuit”)  seeking  a  review  and  reversal  of  the  PTAB’s
decision.  On  September  10,  2018,  the  Federal  Circuit  affirmed  the  PTAB’s  decision  to  terminate  the  interference  proceeding.  The  time  for
UC/Vienna/Charpentier  to  ask  for  a  rehearing  by  the  Federal  Circuit  or  permission  from  the  U.S.  Supreme  Court  to  appeal  has  expired.  Accordingly,  the
Federal Circuit returned the UC/Vienna/Charpentier patent application at issue in the terminated interference to the USPTO. On February 8, 2019, the USPTO
issued a notice allowing the patent application, which, when issued, will cover generally the use of the CRISPR/Cas9 technology using a single RNA guide in
any  setting,  including  cellular  settings. On  June  25,  2019,  PTAB  of  the  USPTO  declared  an  interference  between  the  UC/Vienna/Charpentier  eukaryotic
patent family and the Broad Institute patent family to determine which research group first invented the use of the CRISPR/Cas9 technology in eukaryotic
cells  and,  therefore,  is  entitled  to  the  patents  covering  the  invention.  On  August  26,  2019,  the  PTAB  redeclared  the  interference  to  include  additional
UC/Vienna/Charpentier patent applications covering the invention that had also been found allowable by the USPTO. As of January 31, 2020, the interference
involves 14 allowable patent applications from the UC/Vienna/Charpentier eukaryotic patent family and 13 patents and one patent application from the Broad
Institute patent family. If it were to succeed in the interference, the Broad could seek to assert its issued patents against us based on our CRISPR/Cas9-based
activities,  including  commercialization.  Through  the  end  of  2019,  apart  from  the  interference  the  USPTO  has  issued  or  allowed  over  20  patents  to
UC/Vienna/Charpentier covering compositions and methods of use of the CRISPR/Cas9 technology.

Pioneer Hi-Bred International (DuPont Company) Intellectual Property

Pioneer  Hi-Bred  International  and  its  affiliates,  including  the  DuPont  Company,  have  licensed  to  Caribou  on  a  worldwide  basis,  various  patent  families
relating to CRISPR/Cas systems, components and methods of use generally and CRISPR/Cas9 specifically in certain fields, which include Intellia’s field of
use under our license agreement with Caribou. In July 2015, we exercised our option under the license agreement with Caribou to sublicense these Pioneer
patent families in our field of use. The license from Pioneer to Caribou will expire upon the expiration, abandonment or invalidation of the last patent or
patent application licensed from Pioneer to Caribou.

The licensed Pioneer portfolio includes a family of applications filed by Vilnius University that discloses the components of a CRISPR/Cas9 system required
for gene editing in non-bacterial organisms. On May 2, 2017, the USPTO issued U.S. Patent No. 9,637,739, with claims covering the in vitro assembly and
use of a recombinant CRISPR/Cas9 complex to modify DNA. Patents obtained from this patent family will expire in or after 2033, assuming payment of
necessary maintenance fees. We cannot ensure that these additional applications in this family will lead to issued claims that cover our products or activities.

Invention Management Agreement

On  December  15,  2016,  we  entered  into  a  Consent  to  Assignments,  Licensing  and  Common  Ownership  and  Invention  Management  Agreement  (the
“Invention  Management  Agreement”),  with  the  Regents  of  the  University  of  California,  University  of  Vienna,  Dr.  Charpentier,  Caribou,  CRISPR
Therapeutics AG, ERS Genomics Ltd. and TRACR Hematology Ltd. Under the Invention Management Agreement, Dr. Charpentier retroactively consented
to UC/Vienna’s CRISPR/Cas9 license to Caribou as well as Caribou’s sublicensing to Intellia certain of its rights to the UC/Vienna/Charpentier CRISPR/Cas9
IP, subject to the restrictions of our license from Caribou. Under the agreement, the parties commit to maintain and coordinate the prosecution, defense and
enforcement of the CRISPR/Cas9 foundational patent portfolio worldwide, and each of the co-owners of the IP grants cross-consents to all existing and future
licenses and sublicenses based on the rights of another co-owner. The Invention Management Agreement also includes retroactive approval by certain parties
of certain prior assignments of interests in patent rights to other parties, and provides for, among other things, (i) good faith cooperation among the parties
regarding  patent  maintenance,  defense  and  prosecution,  (ii)  cost-sharing  arrangements,  and  (iii)  notice  of  and  coordination  in  the  event  of  third-party
infringement of the subject patents. Unless earlier terminated by the parties, the Invention Management Agreement will continue in effect until the later of the
last expiration date of the UC/Vienna/Charpentier patents underlying the CRISPR/Cas9 technology, or the date on which the last underlying patent application
is abandoned.

Novartis In-Licensed Intellectual Property

The 2014 Novartis Agreement grants us worldwide, non-exclusive, royalty-free rights to a portfolio of 14 Novartis patent families containing granted patents
and pending applications in the U.S. and internationally relating to LNP compositions, methods of use and modified nucleic acids. The license under the 2014
Novartis  Agreement  permits  us  to  use  the  Novartis  LNPs  to  develop  therapeutic,  prophylactic,  and  palliative  CRISPR-based  in  vivo  products.  Under  a
December 2018 amendment to the 2014 Novartis Agreement, we obtained rights to use these LNPs both in vivo and ex vivo for any genome editing product.
The earliest claimed priority dates for the licensed patent families range from December 2009 through June 2013, and accordingly will expire by or after
December  2030.  The  term  of  the  license  continues  until  the  expiration  of  the  last-to-expire  patent  right  that  is  licensed  to  either  party.  If  we  attempt  to
challenge any of the patents in the licensed families, Novartis may terminate the license on a patent-by-patent basis. We cannot guarantee that our products or
delivery methods will be covered by issued claims in these families.

In addition, under the 2014 Novartis Agreement, Novartis has also granted us rights to use its proprietary small molecule for HSC expansion. Our rights to
this  technology  are  subject  to  a  single-digit  royalty  based  on  whether  we  develop  and  commercialize  the  relevant  product  solely  or  in  collaboration  with
another third party.

Under the 2014 Novartis Agreement, any platform IP developed as part of the collaboration is owned solely by us, while all other IP developed within the
collaboration, including product-based IP, is jointly owned by us and Novartis. We cannot guarantee that IP filed based on collaboration data will result in
issued claims covering our products or delivery methods. Under our agreement with Novartis, we have also granted Novartis a sublicense to the IP we license
under our agreement with Caribou for the Novartis-selected HSC and CAR-T cell products, and in vivo products if applicable, with such sublicense being
exclusive as long as Novartis uses commercially reasonable efforts to develop and commercialize those products.

In December 2018, we entered into an amendment to our agreement with Novartis which expands the scope of the 2014 Novartis Agreement to include the ex
vivo development of CRISPR/Cas9-based cell therapies using limbal stem cells primarily against selected gene targets by Novartis.

Manufacturing

We  have  entered  into  certain  manufacturing  and  supply  arrangements  with  third-party  suppliers  to  support  production  of  our  product  candidates  and  their
components.  We  plan  to  continue  to  rely  on  these  qualified  third-party  organizations  and  our  own  capabilities  to  produce  or  process  bulk  compounds,
formulated compounds, viral vectors or engineered cells for IND-supporting activities and early stage clinical trials. We expect that clinical and commercial
quantities of any in vivo product or engineered cells that we may seek to develop will be manufactured in facilities and by processes that comply with FDA
and other regulations. At the appropriate time in the product development process, we will determine whether to establish manufacturing facilities or continue
to  rely  on  third  parties  to  manufacture  commercial  quantities  of  any  products  that  we  may  successfully  develop.  In  certain  instances,  we  may  consider
building our own commercial infrastructure.

Competition

The  biotechnology  and  pharmaceutical  industries  are  extremely  competitive  in  the  race  to  develop  new  products.  While  we  believe  we  have  significant
competitive advantages with our industry-leading expertise in genome editing, clinical development expertise and dominant IP position, we currently face and
will continue to face competition for our development programs from companies that use genome editing or gene therapy development platforms and from
companies  focused  on  more  traditional  therapeutic  modalities  such  as  small  molecules  and  antibodies.  The  competition  is  likely  to  come  from  multiple
sources,  including  large  and  specialty  pharmaceutical  and  biotechnology  companies,  academic  research  institutions,  government  agencies  and  public  and
private research institutions. Many of these competitors may have access to greater capital and resources than us. For any products that we may ultimately
commercialize, not only will we compete with any existing therapies and those therapies currently in development, but we will also have to compete with new
therapies that may become available in the future.

Competitors in our efforts to provide genetic therapies to patients can be grouped into at least three sets based on their product discovery platforms:

•

•

•

genome editing companies focused on CRISPR based technologies including: Beam Therapeutics Inc., Caribou Biosciences, Inc., CRISPR
Therapeutics, Inc., Editas Medicine, Inc., ToolGen, Inc., Tracr Hematology Limited and Verve Therapeutics, Inc.;

other  genome  editing  companies  including:  Allogene  Therapeutics,  Inc.,  bluebird  bio,  Inc.,  Cellectis  S.A.,  Homology  Medicines,  Inc.,
Poseida, Inc., Precision BioSciences, Inc. and Sangamo Therapeutics, Inc., and;

genome  therapy  companies  developing  in  vivo  or ex  vivo  therapies,  such  as  cell  therapies,  including:  Asklepios  Biopharmaceutical,  Inc.,
bluebird bio, Inc., Cellectis S.A., Bristol Myers Squibb (which acquired Celgene Corporation), Gilead Sciences, Inc. (which acquired Kite
Pharma, Inc.), Novartis A.G., Roche Holding AG (which acquired Spark Therapeutics, Inc.) and Voyager Therapeutics, Inc.

Our competitors will also include companies that are or will be developing other genome editing methods as well as small molecules, biologics, in vivo gene
therapies, engineered cell therapies (both autologous and allogeneic) and nucleic acid-based therapies for the same indications that we are targeting with our
CRISPR/Cas9-based therapeutics.

Government Regulation and Product Approval

As  a  biopharmaceutical  company,  we  are  subject  to  extensive  legal  and  regulatory  requirements.  For  example,  we  may  need  approval  from  regulatory
agencies for our nonclinical and clinical studies, development, manufacturing, distribution, exportation and importation, commercialization, marketing and
reimbursement  relating  to  our  products  and  product  candidates.  Relevant  regulatory  authorities  include,  but  are  not  limited  to,  the  FDA,  the  EMA,  the
Commission of the European Union, EU member state agencies, such as Germany’s Federal Institute for Drugs and Medicinal Devices (“BfArM”), and other
countries’ similar agencies, such as the United Kingdom Medicines and Healthcare Products Regulatory Agency (“MHRA”).

25

 
 
 
 
We expect our future in vivo and ex vivo product candidates to be regulated as biologics. Biological products are subject to regulation under the Food, Drug
and Cosmetic (“FD&C”) Act and the Public Health Service Act (“PHS Act”), and other federal, state, local and foreign statutes and regulations. Both the
FD&C Act and the PHS Act 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 drug and biological products. Before clinical testing of
biological products in the U.S. may begin, we must submit an IND to the FDA, which reviews the clinical protocol and other information, and the IND must
become effective before clinical trials may begin.

Biologic products must be approved by the FDA before they may be legally marketed in the U.S. and by the appropriate foreign regulatory agencies before
they may be legally marketed in foreign countries. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal,
state,  local  and  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.

Within the FDA, the Center for Biologics Evaluation and Research (“CBER”) regulates biological products, including gene and cell therapies. CBER’s Office
of Tissues and Advanced Therapies (“OTAT”) is responsible for oversight of gene therapy and related products, and the Cellular, Tissue and Gene Therapies
Advisory  Committee  (“CTGTAC”)  advises  CBER  on  its  reviews.  Human  gene  therapy  products  are  defined  as  all  products  that  mediate  their  effects  by
transcription or translation of transferred genetic material or by specifically altering host (human) genetic sequences. Some examples of gene therapy products
include nucleic acids, genetically modified microorganisms (e.g., viruses, bacteria, fungi), engineered site-specific nucleases used for human genome editing,
and ex vivo genetically modified human cells. FDA has published guidance documents related to, among other things, gene therapy products in general and
their  preclinical  assessment,  potency  or  other  quality  testing,  and  chemistry,  manufacturing  and  control  information  in  gene  therapy  INDs,  and  long-term
adverse event monitoring of clinical trial subjects; all of which are intended to facilitate industry’s development of these products. More recently and as part
of  the  implementation  of  the  21st  Century  Cures  Act,  FDA  has  issued  a  number  of  guidances  pertaining  to  Regenerative  Medicine  Advanced  Therapies,
which are defined as including cell therapy, therapeutic tissue engineering products, human cell and tissue products and combination products using any such
therapies or products. Additionally, gene therapies, including genetically modified cells, that lead to a durable modification of cells or tissues may meet the
definition  of  a  regenerative  medicine  therapy.  A  number  of  guidances  have  been  revised  to  reflect  the  growing  knowledge  and  incorporation  of  newer
technology, including certain considerations for genome editing. A small, but growing number of gene therapy products have been approved by regulatory
agencies.  In  2012,  the  EMA  authorized  the  marketing  of  the  first  gene  therapy  product  approved  by  regulatory  authorities  anywhere  in  the  Western
world. And  in  the  U.S.,  in  2017,  the  FDA  approved  the  first  two  cell-based,  gene  therapy  products  as  well  as  a  gene  therapy  product.  Additional  gene
therapies have been approved in the U.S. in both 2018 and 2019.

Ethical, social and legal concerns about genome-editing technology, gene therapy, genetic testing and genetic research could result in additional regulations
restricting or prohibiting the processes we may use. Federal and state agencies, congressional committees and foreign governments have expressed interest in
further regulating biotechnology. More restrictive regulations or claims that our products are unsafe or pose a hazard could prevent us from commercializing
any product candidates. New government requirements may be established that could delay or prevent regulatory approval of our product candidates under
development. It is impossible to predict whether legislative changes will be enacted, regulations, policies or guidances changed, or interpretations by agencies
or courts changed, or what the impact of such changes, if any, may be.

U.S. Gene and Cell Therapy Products Development Process

The FDA approves biologics, including gene and cellular therapy products, through the Biologics License Application (“BLA”) process before they may be
legally marketed in the U.S. This process generally involves the following:

•

completion  of  extensive  nonclinical,  sometimes  referred  to  as  preclinical  laboratory  tests,  and  preclinical  animal  studies  and  applicable
requirements  for  the  humane  use  of  laboratory  animals  and  formulation  studies  in  accordance  with  applicable  regulations,  including  good
laboratory practice (“GLP”);

26

 
 
•

•

•

•

•

•

submission to the FDA of an IND application, which must become effective before human clinical trials may begin;

performance of adequate and well-controlled human clinical trials according to the FDA’s regulations commonly referred to as good clinical
practice (“GCP”) and any additional requirements for the protection of human research subjects and their health information, to establish the
safety and efficacy of the proposed product for its intended use;

submission to the FDA of a BLA for marketing approval that includes substantial evidence of safety, purity, and potency, from nonclinical
testing and clinical trials;

satisfactory completion of an FDA inspection of the manufacturing facility or facilities where the product is produced to assess compliance
with current good manufacturing practice (“cGMP”) to assure that the facilities, methods and controls are adequate to preserve the product’s
identity, strength, quality and purity and, if applicable, the FDA’s current good tissue practice (“cGTP”) requirements for the use of human
cellular and tissue products;

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

FDA review and approval of the BLA licensure.

Before testing any drug or biological product candidate, including gene and cellular therapy product candidates, in humans, the product candidate enters the
preclinical testing stage. Preclinical tests, also referred to as nonclinical studies, include laboratory evaluations of product chemistry, toxicity and formulation,
as well as animal studies to assess the potential safety and activity of the product candidate. The conduct of the preclinical tests must comply with federal
regulations and requirements, including GLP.

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 within that 30-day time period. In
such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. The FDA may also impose clinical holds
on a biological product candidate at any time before or during clinical trials due to, among other reasons, safety concerns or non-compliance with regulatory
requirements. 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 trials to begin, or that, once begun, issues will not arise
that result in the suspension or termination of such trials.

Clinical trials involve the administration of the product candidate to healthy volunteers or patients under the supervision of qualified investigators, generally
physicians not employed by or under the study sponsor’s control. Clinical trials are conducted under 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 independent
institutional review board (“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  study  participants  and  considers  such  items  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 his or her legal representative and must monitor the clinical trial until completed. Certain clinical trials also must be reviewed by an institutional
biosafety  committee  (“IBC”),  a  local  institutional  committee  that  reviews  all  forms  of  research  conducted  at  that  institution  involving  recombinant  or
synthetic nucleic acid molecules. The IBC assesses the safety of the research and identifies any potential risk to public health or the environment and ensures
that all research is conducted in compliance with National Institutes of Health (“NIH”) Guidelines for Research Involving Recombinant DNA Molecules.

27

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

•

•

•

Phase  I.  The  product  candidate  is  initially  introduced  into  healthy  human  subjects  and  tested  for  safety.  In  the  case  of  some  products  for
severe or life-threatening diseases, especially when the product may be too inherently toxic to ethically administer to healthy volunteers, the
initial human testing is often conducted in patients.

Phase  II.  The  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 for specific targeted diseases and to determine dosage tolerance, optimal dosage and dosing
schedule.

Phase III. Clinical trials are undertaken to further evaluate dosage, clinical efficacy, potency (for BLA products), and safety in an expanded
patient population at dispersed clinical trial sites. These clinical trials are intended to establish the overall risk/benefit ratio of the product and
provide an adequate basis for product approval and labeling.

Post-approval clinical trials, sometimes referred to as Phase IV clinical trials, may be conducted after initial marketing 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.  The  FDA
typically advises that sponsors observe subjects for potential gene therapy-related delayed adverse events for up to a 15-year period, including a minimum of
five years of annual examinations followed by ten years of annual queries, either in person or by questionnaire.

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  status  of  the  clinical  trials  must  be  submitted  to  the  FDA.  Written  IND  safety  reports  must  be
promptly submitted to the FDA and the investigators for serious and unexpected adverse events, any findings from other trials, tests in laboratory animals
or in vitro testing that suggest a significant risk for 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. Phase I, Phase II and Phase III clinical trials may not be completed successfully
within any specified period, if at all. 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 product candidate has
been associated with unexpected serious harm to patients.

There  also  are  requirements  governing  the  reporting  of  ongoing  clinical  trials  and  completed  clinical  trial  results  to  public  registries.  Sponsors  of  certain
clinical trials of FDA-regulated products, including biologics such as gene and cellular therapy products, are required to register and disclose certain clinical
trial information to NIH. Information related to the product, patient population, phase of investigation, study sites and investigators, and other aspects of the
clinical trial is then made publicly available as part of the registration at www.clinicaltrials.gov. Sponsors also are obligated to disclose the results of their
clinical  trials  after  completion.  Disclosure  of  the  results  of  these  trials  can  be  delayed  until  the  new  product  or  new  indication  being  studied  has  been
approved, up to a maximum of two years.

Human therapeutic products based on genome editing technology are a new category of therapeutics. Because this is a relatively new and expanding area of
novel therapeutic interventions, there can be no assurance as to the length of the study period, the number of patients the FDA will require to be enrolled in
the trials in order to establish the safety, purity and potency for BLA products that are human gene editing therapeutics, or that the data generated in these
trials will be acceptable to the FDA to support marketing approval.

28

 
 
 
 
Concurrent  with  clinical  trials,  companies  usually  complete  additional  animal  trials  and  must  also  develop  additional  information  about  the  physical
characteristics of the product candidate as well as finalize a process for manufacturing the product in commercial quantities in accordance with cGMP, and in
certain cases, cGTP, requirements. To help reduce the risk of the introduction of adventitious agents with use of biological products, the PHS Act 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 things, the sponsor must develop methods for testing the identity, strength,
quality, potency and purity of the final product to support a BLA. Additionally, appropriate packaging must be selected and tested, and stability studies must
be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.

U.S. Review and Approval Processes

After  the  completion  of  clinical  trials  of  a  biological  product  candidate  (such  as  gene  and  cellular  therapy  products),  FDA  approval  of  a  BLA  must  be
obtained  before  commercial  marketing  of  the  product.  The  BLA  must  include  results  of  product  development,  laboratory  and  animal  trials,  human  trials,
information on the manufacture and composition of the product, proposed labeling and other relevant information. In addition, under the Pediatric Research
Equity Act (“PREA”), a BLA or supplement to a BLA, for a product candidate with certain novel characteristics must contain data to assess the safety and
effectiveness of the product candidate for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for each
pediatric  subpopulation  for  which  the  product  is  safe  and  effective.  The  Food  and  Drug  Administration  Safety  and  Innovation  Act  of  2012  (“FDASIA”)
requires that a sponsor who is planning to submit a marketing application for a biological product that includes a new active ingredient, new indication, new
dosage form, new dosing regimen or new route of administration submit an initial Pediatric Study Plan (“PSP”) within sixty days after an end-of-Phase 2
meeting or as may be agreed between the sponsor and FDA. The initial PSP must include, among other things, an outline of the pediatric study or studies that
the sponsor plans to conduct, including, to the extent practicable, study objectives and design, age groups, relevant endpoints and statistical approach, or a
justification for not including such detailed information, and any request for a deferral of pediatric assessments or a full or partial waiver of the requirement to
provide  data  from  pediatric  studies  along  with  supporting  information,  along  with  any  other  information  specified  in  FDA  regulations.  The  FDA  and  the
sponsor must reach agreement on the PSP. A sponsor can submit amendments to an agreed-upon initial PSP at any time if changes to the pediatric plan need
to be considered based on data collected from nonclinical studies, early phase clinical trials, or other clinical development programs. The FDA may grant
deferrals for submission of data or full or partial waivers. Unless otherwise required by regulation, PREA does not apply to any biological product for an
indication  for  which  orphan  designation  has  been  granted.  The  testing  and  approval  processes  require  substantial  time  and  effort  and  there  can  be  no
assurance that the FDA will accept the BLA for filing and, even if filed, that any approval will be granted on a timely basis, if at all.

Under the Prescription Drug User Fee Act (“PDUFA”), as amended, each BLA must be accompanied by a user fee. The FDA adjusts the PDUFA user fees on
an annual basis. 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.  Additionally,  no  user  fees  are  assessed  on  BLAs  for  products  designated  as  orphan  drugs,  unless  the  product  also  includes  a  non-orphan
indication.

Within 60 days following submission of the application, the FDA reviews the BLA 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,  including  for  failure  to  pay
required fees, and may request additional information. In this event, the application 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 application to determine, among other things, whether the proposed product is safe and effective (or, in the case of
biological  products,  safe,  pure  and  potent),  and  whether  the  product  is  being  manufactured  in  accordance  with  cGMP,  and  in  certain  cases,  cGTP,
requirements to assure and preserve the product’s identity, safety, strength, quality, potency and purity. The FDA may refer applications for novel products or
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 FDA review and approval
process,  the  FDA  also  will  determine  whether  a  Risk  Evaluation  and  Mitigation  Strategy  (“REMS”)  is  necessary  to  assure  the  safe  use  of  the  drug  or
biological product candidate. If the FDA concludes a REMS is needed, the sponsor of the BLA must submit a proposed REMS; the FDA will not approve the
application without a REMS, if required.

29

 
Before approving a BLA, the FDA will inspect the facilities at which the product is manufactured. The FDA will not approve the product unless it determines
that  the  manufacturing  processes  and  facilities  are  in  compliance  with  cGMP  and,  if  applicable,  cGTP  requirements  are  adequate  to  assure  consistent
production of the product within required specifications. Additionally, before approving a BLA, the FDA will typically inspect one or more clinical sites to
assure  that  the  clinical  trials  were  conducted  in  compliance  with  IND  study  requirements  and  GCP  requirements.  To  assure  cGMP,  cGTP  and  GCP
compliance, an applicant must incur significant expenditure of time, money and effort in the areas of training, record keeping, production, and quality control.

Notwithstanding  the  submission  of  relevant  data  and  information,  the  FDA  may  ultimately  decide  that  the  BLA  does  not  satisfy  its  regulatory  criteria  for
approval and deny approval. Data obtained from clinical trials are not always conclusive and the FDA may interpret data differently than we interpret the
same data. If the agency decides not to approve the BLA in its present form, the FDA will issue a complete response letter that usually describes all of the
specific deficiencies in the application identified by the FDA. The deficiencies identified may be minor, for example, requiring clarifying labeling changes, or
major, for example, requiring product reformulation or additional clinical trials. Additionally, the complete response letter may include recommended actions
that the applicant might take to place the application in a condition for approval. If a complete response letter is issued, the applicant may either resubmit the
application, addressing all of the deficiencies identified in the letter, challenge the determination set forth in the letter by requesting a hearing or withdraw the
application.

If a product receives regulatory approval, the approval may be significantly limited to specific diseases, dosages or patient subgroups or the indications for
use  may  otherwise  be  limited,  which  could  restrict  the  commercial  value  of  the  product.  Further,  the  FDA  may  require  that  certain  contraindications,
warnings,  precautions  or  adverse  events  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 IV clinical trials, designed to further assess a product’s safety and effectiveness, and testing and surveillance programs
to monitor the safety of approved products that have been commercialized.

One of the performance goals agreed to by the FDA under the PDUFA VI (Fiscal Years 2018-2022) is to review 90% of BLAs in 10 months from the 60-day
filing date, and 90% of priority BLAs in six months from the 60-day filing date, 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 with PDUFA reauthorization. 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, also known as a Major Amendment, within the last three months before the PDUFA goal date.

Orphan Drug Designation

The  FDA  may  grant  Orphan  Drug  Designation  to  biological  products,  including  cellular  and  gene  therapy  products,  intended  to  treat  a  rare  disease  or
condition  that  affects  fewer  than  200,000  individuals  in  the  U.S.,  or,  if  it  affects  more  than  200,000  individuals  in  the  U.S.,  when  there  is  no  reasonable
expectation that the cost of developing and marketing the product for this type of disease or condition will be recovered from sales in the U.S. Orphan product
designation  must  be  requested  before  submission  of  BLA.  After  the  FDA  grants  orphan  product  designation,  the  identity  of  the  therapeutic  agent  and  its
potential  orphan  use  are  disclosed  publicly  by  the  FDA.  Orphan  product  designation  does  not  convey  any  advantage  in  or  shorten  the  duration  of  the
regulatory review and approval process.

In the U.S., Orphan Drug Designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages
and user-fee waivers. In addition, if a product receives the first FDA approval for the indication for which it has orphan designation, the product is entitled to
orphan drug exclusivity, which means the FDA may not approve any other application to market the same drug for the same orphan indication for a period of
seven years, except in limited circumstances, such as a showing of clinical superiority over the product with orphan exclusivity or where the manufacturer
with orphan exclusivity is unable to assure sufficient quantities of the approved orphan designated product. Competitors, however, may receive approval of
different products for the indication for which the orphan product has exclusivity or obtain approval for the same product but for a different indication for
which the orphan product has exclusivity, which may permit off-label use for the orphan indication. Orphan product exclusivity also could block the approval
of one of our products for seven years if a competitor obtains approval of the same drug or biological product as defined by the FDA for the same orphan
indication or if our product candidate is determined to be contained within the competitor’s product for the same indication or disease. If a drug or biological
product  designated  as  an  orphan  product  receives  marketing  approval  for  an  indication  broader  than  what  is  designated,  it  may  not  be  entitled  to  orphan
product exclusivity.

Expedited Development and Review Programs

In the U.S. and the EU, as well as in other countries, there are a number of programs to expedite development, review and approval of products for serious or
life-threatening disease or condition that address an unmet medical need in the relevant regulatory jurisdiction. In the U.S., these FDA programs include Fast
Track  Designation,  priority  review,  accelerated  approval  and  breakthrough  designation.  Similar  programs  in  the  EU  include  accelerated  assessment,
conditional approval and PRIME, which stands for priority medicines.

The  FDA’s  Fast  Track  program  intends  to  expedite  or  facilitate  the  process  for  reviewing  new  drug  and  biological  products  that  meet  certain  criteria.
Specifically, new biological products are eligible for Fast Track designation if they are intended to treat a serious or life-threatening disease or condition and
demonstrate the potential to address unmet medical needs for the disease or condition. Fast Track designation applies to the combination of the product and
the specific indication for which it is being studied. The sponsor of a new biologic, including gene and cellular therapy products, may request that the FDA
designate the product as a Fast Track product at any time during the product’s clinical development, but ideally not later than the pre-BLA meeting. The FDA
may consider for review sections of the marketing application for a Fast Track product on a rolling basis before the complete application is submitted, if the
sponsor provides a schedule for the submission of the sections of the application, the FDA agrees to accept sections of the application and determines that the
schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the application.

In the U.S., any product is eligible for priority review if it treats a serious condition and, if approved, would provide a significant improvement in safety or
effectiveness  of  the  treatment,  prevention,  or  diagnosis  of  that  condition.  The  FDA  will  attempt  to  direct  additional  resources  to  the  evaluation  of  an
application for a new drug or biological product designated for priority review in an effort to facilitate the review. Additionally, a product may be eligible for
accelerated approval. Biological products studied for their safety and effectiveness in treating serious or life-threatening illnesses and that provide meaningful
therapeutic benefit over existing treatments may be eligible for accelerated approval, which means that they may be approved on the basis of adequate and
well-controlled clinical trials establishing that the product has an effect on a surrogate endpoint that is reasonably likely to predict a clinical benefit, or on the
basis of an effect on a clinical endpoint other than survival or irreversible morbidity or mortality or other clinical benefit, taking into account the severity,
rarity or prevalence of the condition and the availability or lack of alternative treatments. As a condition of approval, the FDA may require that a sponsor of a
product  subject  to  accelerated  approval  perform  adequate  and  well-controlled,  post-marketing  clinical  trials.  In  addition,  the  FDA  currently  requires  as  a
condition for accelerated approval pre-approval of promotional materials, which could adversely impact the timing of the commercial launch of the product.

In addition, under the provisions of the FDASIA, the FDA established a Breakthrough Therapy Designation, which is intended to expedite the development
and review of products that treat serious or life-threatening diseases or conditions. A breakthrough therapy is defined as a drug or biological product that is
intended, alone or in combination with one or more other drugs, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence
indicates that the drug may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial
treatment effects observed early in clinical development. The designation includes all of the features of Fast Track designation, as well as more intensive FDA
interaction and guidance. The Breakthrough Therapy Designation is a distinct status from both accelerated approval and priority review, but these can also be
granted to the same product candidate if the relevant criteria are met. The FDA must take certain actions, such as holding timely meetings and providing
advice,  intended  to  expedite  the  development  and  review  of  an  application  for  approval  of  a  breakthrough  therapy.  All  requests  for  breakthrough  therapy
designation will be reviewed within 60 days of receipt, and FDA will either grant or deny the request.

Orphan  designation,  Fast  Track  designation,  priority  review,  accelerated  approval  and  breakthrough  therapy  designation  do  not  change  the  standards  for
approval but may expedite the development or approval process. Where applicable, we plan to request Fast Track and Breakthrough Therapy Designation for
our product candidates. Even if we receive one or both of these designations for our product candidates, the FDA may later decide that our product candidates
no longer meet the conditions for qualification. In addition, these designations may not provide us with a material commercial advantage.

Regenerative medicine advanced therapies (“RMAT”) designation

As part of the 21st Century Cures Act, the FD&C Act was amended to facilitate an efficient development program for, and expedite review of regenerative
medicine advanced therapies, which include cell and gene therapies, therapeutic tissue engineering products, human cell and tissue products, and combination
products  using  any  such  therapies  or  products.  This  program  is  intended  to  facilitate  efficient  development  and  expedite  review  of  regenerative  medicine
therapies, which are intended to treat, modify, reverse, or cure a serious or life-threatening disease or condition and qualify for RMAT designation. A drug
sponsor  may  request  that  FDA  designate  a  drug  as  a  RMAT  concurrently  with  or  at  any  time  after  submission  of  an  IND.  FDA  has  60  calendar  days  to
determine whether the drug meets the criteria, including whether there is preliminary clinical evidence indicating that the drug has the potential to address
unmet medical needs for a serious or life-threatening disease or condition. A BLA for a regenerative medicine therapy that has received RMAT designation
may be eligible for priority review or accelerated approval through use of surrogate or intermediate endpoints reasonably likely to predict long-term clinical
benefit, or reliance upon data obtained from a meaningful number of sites. Benefits of RMAT designation also include early interactions with FDA and, for
those  granted  accelerated  approval,  post-approval  requirements  may  be  fulfilled  through  the  submission  of  clinical  evidence  from  clinical  studies,  patient
registries,  or  other  sources  of  real-world  evidence,  such  as  electronic  health  records;  the  collection  of  larger  confirmatory  data  sets;  or  post-approval
monitoring of all patients treated with such therapy prior to its approval.

Post-Approval Requirements

Maintaining  substantial  compliance  with  applicable  federal,  state,  and  local  statutes  and  regulations  and,  as  applicable,  their  counterparts  in  other
jurisdictions, requires the expenditure of substantial time and financial resources. Rigorous and extensive FDA regulation of biological products, including
gene and cellular therapy products, continues after approval, particularly with respect to cGMP requirements. We will rely, and expect to continue to rely, on
third parties for the production of clinical and commercial quantities of certain components of products that we may commercialize. Manufacturers of our
products  are  required  to  comply  with  applicable  requirements  in  the  cGMP  regulations,  including  quality  control,  quality  assurance  and  maintenance  of
records  and  documentation.  Other  post-approval  requirements  applicable  to  biological  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.  As  part  of  the  manufacturing  process,  the  manufacturer  is  required  to  perform  certain  tests  on  each  lot  of  the  product  before  it  is  released  for
distribution.  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 of the manufacturer’s tests performed on the lot. The FDA
also may perform certain confirmatory tests on lots of some products, such as viral vaccines, before releasing the lots for distribution by the manufacturer. In
addition,  the  FDA  conducts  laboratory  research  related  to  the  regulatory  standards  on  the  safety,  purity,  potency,  and  effectiveness  of  biological  products,
including gene and cellular therapy products.

We  also  would  have  to  comply  with  the  FDA’s  advertising  and  promotion  requirements,  such  as  those  related  to  direct-to-consumer  advertising,  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”),
industry-sponsored scientific and educational activities, and promotional activities involving the internet and social media platforms. Discovery of previously
unknown problems or the failure to comply with the applicable regulatory requirements may result in restrictions on the labeling or marketing of a product,
imposition of a REMS or post-market study requirement or withdrawal of the product from the market as well as possible civil or criminal sanctions. Failure
to  comply  with  the  applicable  U.S.  requirements  at  any  time  during  the  product  development  process,  approval  process  or  after  approval,  may  subject  an
applicant  or  manufacturer  to  administrative  or  judicial  civil  or  criminal  sanctions  and  adverse  publicity.  FDA  sanctions  could  include  refusal  to  approve
pending  applications,  withdrawal  of  an  approval,  clinical  hold,  warning  or  untitled  letters,  product  recalls,  product  seizures,  total  or  partial  suspension  of
production or distribution, injunctions, fines, refusals of government contracts, mandated corrective advertising or communications with doctors, debarment,
restitution, disgorgement of profits, or civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us.

32

 
Biological product manufacturers and other entities involved in the manufacture and distribution of approved biological products, including gene and cellular
therapy products, in the U.S. are required to register their establishments with the FDA and certain other federal and state agencies, and are subject to periodic
unannounced inspections by the FDA and certain other federal and state agencies for compliance with cGMP, and in certain cases, cGTP, requirements and
other  laws.  Accordingly,  manufacturers  must  continue  to  expend  time,  money,  and  effort  in  the  area  of  production  and  quality  control  to  maintain  cGMP
compliance.  Discovery  of  problems  with  a  product  after  approval  may  result  in  restrictions  on  a  product,  manufacturer,  or  holder  of  an  approved  BLA,
including withdrawal of the product from the market, as well as potential civil and criminal liability. 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.

Biosimilars and Exclusivity

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010 (collectively, the “Affordable Care
Act”  or  “ACA”),  signed  into  law  on  March  23,  2010,  includes  a  subtitle  called  the  Biologics  Price  Competition  and  Innovation  Act  of  2009  (“BPCIA”),
which created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA-licensed reference biological
product in the U.S. Starting in 2015, the FDA commenced licensing biosimilars under the BPCIA, and there are currently numerous biosimilars approved in
the  U.S.  and  Europe.  The  FDA  has  issued  several  draft  and  final  guidance  documents  outlining  an  approach  to  review  and  approval  of  biosimilars  and
interchangeable biological products.

The  BPCIA  also  contains  various  provisions  regarding  exclusivity  for  reference  and  interchangeable  products  and  procedures  for  sharing  and  litigating
patents covering the reference product. The BPCIA, however, is complex and only beginning to be interpreted and implemented by the FDA. In addition,
proposed  legislation  has  sought  to  reduce  the  12-year  reference  product  exclusivity  period.  Other  aspects  of  the  BPCIA,  some  of  which  may  impact  the
BPCIA exclusivity provisions, have also been the subject of recent litigation. As a result, the ultimate impact, implementation, and meaning of the BPCIA is
subject to significant uncertainty.

Additional Regulation

In  addition  to  the  foregoing,  state  and  federal  laws  regarding  environmental  protection  and  hazardous  substances,  including  the  Occupational  Safety  and
Health Act, the Resource Conservancy and Recovery Act and the Toxic Substances Control Act, all affect our business. These and other laws govern our use,
handling and disposal of various biological, chemical and radioactive substances used in, and wastes generated by, our operations. If our operations result in
contamination of the environment or expose individuals to hazardous substances, we could be liable for damages and governmental fines. We believe that we
are  in  material  compliance  with  applicable  environmental  laws  and  that  continued  compliance  therewith  will  not  have  a  material  adverse  effect  on  our
business. We cannot predict, however, how changes in these laws may affect our future operations.

Other Healthcare and Privacy Laws

In addition to FDA restrictions on marketing of biological products, other U.S. federal and state healthcare regulatory laws restrict business practices in the
pharmaceutical industry, which include, but are not limited to, state and federal anti-kickback, false claims, data privacy and security, and physician payment
transparency laws. The laws that may affect our ability to operate include:

•

the  federal  Anti-Kickback  Statute,  which  prohibits,  among  other  things,  individuals  or  entities  from  knowingly  and  willfully  soliciting,
receiving, offering or paying any remuneration (including any kickback, bribe, or certain rebates), directly or indirectly, overtly or covertly, in
cash  or  in  kind,  to  induce,  or  in  return  for,  either  the  referral  of  an  individual,  or  the  purchase,  lease,  order,  arrangement  for  or
recommendation of the purchase, lease, order, arrangement for any good, facility, item or service, for which payment may be made, in whole
or in part, under a federal healthcare program, such as the Medicare and Medicaid programs. A person or entity does not need to have actual
knowledge of the statute or specific intent to violate it in order to have committed a violation. In addition, the ACA provides that a claim
including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes
of  the  federal  False  Claims  Act  (“FCA”).  Violators  are  subject  to  civil  and  criminal  fines  and  penalties,  as  well  as  imprisonment  and
exclusion from government healthcare programs;

33

 
 
•

•

•

•

•

federal civil and criminal false claims laws, including, without limitation, the federal FCA, and civil monetary penalty laws which prohibit,
among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment or approval from the
federal government, including Medicare, Medicaid and other government payors, that are false or fraudulent or knowingly making, using or
causing to be made or used a false record or statement material to a false or fraudulent claim or to avoid, decrease or conceal an obligation to
pay money to the federal government, or knowingly concealing or knowingly and improperly avoiding or decreasing an obligation to pay
money to the federal government. A claim includes “any request or demand” for money or property presented to the U.S. federal government.
Manufacturers can be held liable under the FCA even when they do not submit claims directly to government payors if they are deemed to
“cause”  the  submission  of  false  or  fraudulent  claims  by,  for  example,  promoting  a  product  off-label.  The  FCA  also  permits  a  private
individual  acting  as  a  “whistleblower”  to  bring  civil  whistleblower  or  qui  tam  actions  against  individuals  (including  biopharmaceutical
manufacturers and sellers) on behalf of the federal government alleging violations of the FCA and to share in any monetary recovery. These
laws impose criminal and civil penalties on violators;

the federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), and its implementing regulations, which impose criminal
and civil liability for knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or
obtain, by means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody
or  control  of,  any  healthcare  benefit  program,  regardless  of  the  payor  (e.g.,  public  or  private)  and  knowingly  and  willfully  falsifying,
concealing or covering up by any trick or device a material fact or making any materially false statements in connection with the delivery of,
or payment for, healthcare benefits, items or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have
actual knowledge of the statute or specific intent to violate it in order to have committed a violation. HIPAA violations can lead to civil and
criminal liability;

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 (“HITECH”), and their respective
implementing  regulations,  which  impose,  among  other  things,  requirements  on  certain  covered  healthcare  providers,  health  plans,  and
healthcare clearinghouses as well as their respective business associates that perform services for them that involve the use, or disclosure of,
individually identifiable health information, relating to the privacy, security and transmission of individually identifiable health information
without appropriate authorization. HITECH also created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal
penalties  directly  applicable  to  business  associates,  and  gave  state  attorneys  general  new  authority  to  file  civil  actions  for  damages  or
injunctions  in  federal  courts  to  enforce  the  federal  HIPAA  laws  and  seek  attorneys’  fees  and  costs  associated  with  pursuing  federal  civil
actions.  In  addition,  state  and  non-U.S.  laws  govern  the  privacy  and  security  of  health  and  other  personal  information  in  certain
circumstances, many of which differ from each other in significant ways and may not have the same requirements, thus complicating efforts
to comply with their respective provisions;

the  U.S.  federal  physician  payment  transparency  requirements,  sometimes  referred  to  as  the  “Physician  Payments  Sunshine  Act,”  created
under the ACA, and their implementing regulations, which require manufacturers of drugs, devices, biologics and medical supplies for which
payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report annually, to
the Centers for Medicare and Medicaid Services (“CMS”), information related to payments or other “transfers of value” made to physicians
(defined to include doctors, dentists, optometrists, podiatrists and chiropractors), other healthcare providers, and teaching hospitals, as well as
ownership and investment interests held by physicians, other healthcare providers, and their immediate family members. Failure to submit
required information may result in civil monetary penalties for all payments, transfers of value or ownership or investment interests that are
not timely, accurately, and completely reported in an annual submission. Effective January 1, 2022, these reporting obligations will extend to
include transfers of value made to certain non-physician providers, such as physician assistants and nurse practitioners;

federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially harm
consumers;

34

 
 
 
 
 
 
•

•

•

the Foreign Corrupt Practices Act (“FCPA”) and other laws which prohibit improper payments or offers of payments to foreign governments
and their officials and political parties by U.S. persons and issuers as defined by the statute for the purpose of obtaining or retaining business;

the FD&C Act, which prohibits, among other things, the commercialization of adulterated or misbranded drugs and medical devices and the
PHS Act, which prohibits, among other things, the commercialization of biological products unless a biologics license is in effect; and

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

Because of the breadth of these laws and the limited statutory exceptions and safe harbors available, it is possible that some of our business activities could be
subject to challenge under one or more of such laws.

In the event we decide to conduct clinical trials or enroll subjects in our future clinical trials, we may be subject to additional privacy restrictions. As of May
25, 2018, the General Data Protection Regulation (“GDPR”) regulates the collection, use, storage, disclosure, transfer or other processing of personal data,
including personal health data, in the EU. The GDPR covers any business, regardless of its location, that provides goods or services to residents in the EU
and,  thus,  could  incorporate  our  activities  in  EU  member  states.  The  GDPR  imposes  strict  requirements  on  controllers  and  processors  of  personal  data,
including special protections for “sensitive information,” which includes health and genetic information of individuals residing in the EU, obtaining consent
of the individuals to whom the personal data relates, providing information to individuals regarding data processing activities, implementing safeguards to
protect  the  security  and  confidentiality  of  personal  data,  providing  notification  of  data  breaches,  and  taking  certain  measures  when  engaging  third-party
processors. GDPR grants individuals the opportunity to object to the processing of their personal information, allows them to request deletion of personal
information in certain circumstances, and provides the individual with an express right to seek legal remedies in the event the individual believes his or her
rights have been violated. Further, the GDPR imposes strict rules on the transfer of personal data out of the EU to regions that have not been deemed to offer
“adequate” privacy protections, such as the U.S. currently. Failure to comply with the requirements of the GDPR and the related national data protection laws
of the EU member states, which may deviate slightly from the GDPR, may result in warning letters, mandatory audits and financial penalties, including fines
of up to 4% of annual global revenues, or €20,000,000, whichever is greater. As a result of the implementation of the GDPR, we may be required to put in
place additional mechanisms ensuring compliance with the new data protection rules, including as implemented by individual countries. Further, the United
Kingdom’s  exit  from  the  EU,  often  referred  to  as  Brexit,  has  created  uncertainty  with  regard  to  data  protection  regulation  in  the  United  Kingdom.  In
particular, it is unclear how data transfers to and from the United Kingdom will be regulated, and what other aspects of EU privacy laws will be adopted,
rejected or modified by the United Kingdom. Additionally, California recently enacted the California Consumer Privacy Act (“CCPA”), which creates new
individual privacy rights for California consumers (as defined in the law) and places increased privacy and security obligations on entities handling personal
data of consumers or households. The CCPA will require covered companies to provide new disclosure to consumers about such companies’ data collection,
use  and  sharing  practices,  provide  such  consumers  new  ways  to  opt-out  of  certain  sales  or  transfers  of  personal  information,  and  provide  consumers  with
additional  causes  of  action.  The  CCPA  went  into  effect  on  January  1,  2020,  and  the  California  Attorney  General  will  commence  enforcement  actions  for
violations beginning July 1, 2020. The California Attorney General has proposed draft regulations, which have not been finalized to date, that may further
impact our business activities if they are adopted. The uncertainty surrounding the implementation of CCPA exemplifies the vulnerability of our business to
the evolving regulatory environment related to personal data and protected health information.

35

 
 
 
 
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, administrative, civil and criminal penalties, damages, fines, disgorgement, contractual damages, reputational harm, diminished
profits and future earnings, the curtailment or restructuring of our operations, exclusion from participation in federal and state healthcare programs, individual
imprisonment, and additional  reporting  obligations  and  oversight  if  we  become  subject  to  a  corporate  integrity  agreement  or  other  agreement  to  resolve
allegations of non-compliance with this law, any of which could adversely affect our ability to operate our business and our financial results.

To the extent that any of our product candidates, once approved, are sold in a foreign country, we may be subject to similar foreign laws and regulations,
which  may  include,  for  instance,  applicable  post-marketing  requirements,  including  safety  surveillance,  anti-fraud  and  abuse  laws,  and  implementation  of
corporate compliance programs and reporting of payments or other transfers of value to healthcare professionals.

Regulation in the European Union

In  the  European  Union,  medicinal  products,  including  advanced  therapy  medicinal  products,  (“ATMP”s),  are  subject  to  extensive  pre-  and  post-market
regulation  by  regulatory  authorities  at  both  the  EU  and  national  levels.  ATMPs  comprise  gene  therapy  products,  somatic  cell  therapy  products  and  tissue
engineered products, which are cells or tissues that have undergone substantial manipulation and that are administered to human beings in order to regenerate,
repair or replace a human tissue. We anticipate that our gene therapy development products would be regulated as ATMPs in the EU.

To obtain regulatory approval of an investigational product under EU regulatory systems, we must submit a marketing authorization application (“MAA”).
The application used to submit the BLA in the U.S. is similar to that required in the EU, with the exception of, among other things, region-specific document
requirements.  The  EU  also  provides  opportunities  for  market  exclusivity.  For  example,  in  the  EU,  upon  receiving  marketing  authorization,  innovative
medicinal products generally receive eight years of data exclusivity and an additional two years of market exclusivity. Data exclusivity prevents regulatory
authorities in the EU from referencing the innovator’s data to assess a generic or biosimilar application during the eight year period. During the additional
two-year period of market exclusivity, a generic or biosimilar marketing authorization can be submitted, and the innovator’s data may be referenced, but no
generic or biosimilar product can be marketed until the expiration of the market exclusivity period. However, there is no guarantee that a product will be
considered by the EU’s regulatory authorities to be an innovative medicinal product, and products may therefore not qualify for data exclusivity. Products
with an orphan designation in the EU will, upon the grant of a marketing authorization for an orphan product, receive ten years of market exclusivity, during
which time no “similar medicinal product” for the same indication may be placed on the market. A “similar medicinal product” is defined as a medicinal
product  containing  a  similar  active  substance  or  substances  as  contained  in  an  authorized  orphan  medicinal  product,  and  which  is  intended  for  the  same
therapeutic indication. An orphan product can also obtain an additional two years of market exclusivity in the EU where an agreed Pediatric Investigation
Plan (“PIP”) for pediatric studies has been complied with. No extension to any supplementary protection certificate can be granted on the basis of pediatric
studies for orphan indications.

The  criteria  for  designating  an  “orphan  medicinal  product”  in  the  EU  are  similar  in  principle  to  those  in  the  U.S.  Under  Article  3  of  Regulation  (EC)
141/2000, a medicinal product may be designated as an orphan medicinal product if it is intended for the diagnosis, prevention or treatment of (1) a life-
threatening  or  chronically  debilitating  condition  affecting  no  more  than  five  in  10,000  persons  in  the  EU  when  the  application  is  made;  or  (2)  a  life-
threatening, seriously debilitating or serious and chronic condition in the EU  and that without the benefits derived from orphan status, would not generate
sufficient return in the EU to justify investment; and (3) there exists no satisfactory method of diagnosis, prevention or treatment of such condition authorized
for marketing in the EU, or if such a method exists, the product will be of significant benefit to those affected by the condition, as defined in Regulation (EC)
847/2000.  Orphan  medicinal  products  are  eligible  for  financial  incentives  such  as  reduction  of  fees  or  fee  waivers  and  are,  upon  grant  of  a  marketing
authorization,  entitled  to  ten  years  of  market  exclusivity  for  the  approved  therapeutic  indication.  The  application  for  orphan  drug  designation  must  be
submitted before the application for marketing authorization. The applicant will receive a fee reduction for the MAA if the orphan drug designation has been
granted,  but  not  if  the  designation  is  still  pending  at  the  time  the  marketing  authorization  is  submitted.  Orphan  drug  designation  does  not  convey  any
advantage in, or shorten the duration of, the regulatory review and approval process.

36

 
The 10-year market exclusivity may be reduced to six years if, at the end of the fifth year, it is established that the product no longer meets the criteria for
orphan  designation,  for  example,  if  the  product  is  sufficiently  profitable  not  to  justify  maintenance  of  market  exclusivity.  Additionally,  marketing
authorization may be granted to a similar product for the same indication at any time if:

•

•

•

The second applicant can establish that its product, although similar, is safer, more effective or otherwise clinically superior;

The applicant consents to a second orphan medicinal product application; or

The applicant cannot supply enough orphan medicinal product.

For other countries outside of the EU, such as countries in Eastern Europe, Latin America or Asia, the requirements governing the conduct of clinical trials,
product licensing, pricing and reimbursement vary from country to country. In all cases, again, the clinical trials must be conducted in accordance with GCP
and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.

If we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines, suspension of clinical trials, suspension
or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

Pediatric development

In the EU, companies developing a new medicinal product must agree upon a PIP with the EMA, and must conduct pediatric clinical trials in accordance with
that PIP, unless a waiver applies, (e.g., because the relevant disease or condition occurs only in adults). The MAA for the product must include the results of
pediatric clinical trials conducted in accordance with the PIP, unless a waiver applies, or a deferral has been granted, in which case the pediatric clinical trials
must be completed at a later date. Products that are granted a marketing authorization on the basis of the pediatric clinical trials conducted in accordance with
the PIP are eligible for a six month extension of the protection under a supplementary protection certificate (if any is in effect at the time of approval) or, in
the case of orphan medicinal products, a two year extension of the orphan market exclusivity. This pediatric reward is subject to specific conditions and is not
automatically available when data in compliance with the PIP are developed and submitted.

Post-approval controls

The  holder  of  a  marketing  authorization  must  establish  and  maintain  a  pharmacovigilance  system  and  appoint  an  individual  qualified  person  for
pharmacovigilance, who is responsible for oversight of that system. Key obligations include expedited reporting of suspected serious adverse reactions and
submission of periodic safety update reports (“PSUR”s).

All new MAAs must include a risk management plan (“RMP”), describing the risk management system that the company will put in place and documenting
measures to prevent or minimize the risks associated with the product. The regulatory authorities may also impose specific obligations as a condition of the
marketing  authorization.  Such  risk-minimization  measures  or  post-authorization  obligations  may  include  additional  safety  monitoring,  more  frequent
submission of PSURs, or the conduct of additional clinical trials or post-authorization safety studies. RMPs and PSURs are routinely available to third parties
requesting access, subject to limited redactions.

All advertising and promotional activities for the product must be consistent with the approved Summary of Product Characteristics and therefore all off-label
promotion is prohibited. Direct-to-consumer advertising of prescription medicines is also prohibited in the EU. Although general requirements for advertising
and promotion of medicinal products are established under EU directives, the details are governed by regulations in each EU member state and can differ
from one country to another.

37

 
 
 
 
Other Government Regulation

In  addition  to  the  healthcare  laws  and  regulations  in  the  U.S.  and  EU  discussed  above,  we  may  be  subject  to  a  variety  of  regulations  in  these  and  other
jurisdictions governing, among other things, animal research, clinical studies, manufacture, marketing approval, and any commercial sales and distribution of
biological products. Because biologically sourced raw materials are subject to unique contamination risks, their use may be restricted in some countries.

Coverage and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any biological product for which we obtain regulatory approval. In the U.S. and
markets  in  other  countries,  patients  who  are  prescribed  treatments  for  their  conditions  and  providers  performing  the  prescribed  services  generally  rely  on
third-party  payors  to  reimburse  all  or  part  of  the  associated  healthcare  costs.  Patients  are  unlikely  to  use  our  products  unless  coverage  is  provided  and
reimbursement  is  adequate  to  cover  a  significant  portion  of  the  cost  of  our  products.  Sales  of  any  products  for  which  we  receive  regulatory  approval  for
commercial  sale  will  therefore  depend,  in  part,  on  the  availability  of  coverage  and  adequate  reimbursement  from  third-party  payors.  Third-party  payors
include government authorities, managed care providers, health maintenance organizations, private health insurers and other organizations.

In the U.S., no uniform policy of coverage and reimbursement for biological products, including gene and cellular therapy products, exists among third-party
payors. As a result, obtaining coverage and reimbursement approval for such a product from a government or other third-party payor is a time-consuming and
costly process that could require us to provide to each payor supporting scientific, clinical and cost-effectiveness data regarding the products’ clinical benefits
and risks on a payor-by-payor basis, with no assurance that coverage and adequate reimbursement will be obtained. Even if we obtain coverage for a given
product, the resulting reimbursement payment rates might not be adequate for us to achieve or sustain profitability or may require co-payments that patients
find  unacceptably  high.  Additionally,  third-party  payors  may  not  cover,  or  provide  adequate  reimbursement  for,  long-term  follow-up  evaluations  required
following the use of our gene-modifying products. Patients are unlikely to use, and health care providers may not prescribe, our product candidates unless
coverage is provided, and reimbursement is adequate to cover a significant portion of the product’s cost to the patient. Because our product candidates may
have a higher cost of goods than conventional therapies, and may require long-term follow up evaluations, the risk that coverage and reimbursement rates
may be inadequate for us to achieve profitability may be greater. Moreover, increasing efforts by governmental and third-party payors in the U.S. and abroad
to cap or reduce healthcare costs may cause such organizations to limit both coverage and the level of reimbursement for biological products and, as a result,
they may not cover or provide adequate payment for our product candidates. In addition, we expect to experience pricing pressures in connection with the sale
of  any  of  our  product  candidates  upon  their  approval  due  to  the  trend  toward  managed  healthcare,  the  increasing  influence  of  health  maintenance
organizations,  cost  containment  initiatives  and  additional  legislative  changes.  For  these  reasons,  there  is  significant  uncertainty  related  to  coverage  and
reimbursement of our future products. It is difficult to predict at this time what third-party payors will decide with respect to the coverage and reimbursement
for our product candidates.

Third‑party and government payors are increasingly reducing reimbursements for medical products and services. Additionally, the containment of healthcare
costs has become a priority of federal and state governments, and the prices of drugs have been a focus in this effort. The U.S. government, state legislatures
and foreign governments have shown significant interest in implementing cost‑containment programs, including price controls, restrictions on reimbursement
and requirements for substitution of generic products. Adoption of price controls and cost‑containment measures, and adoption of more restrictive policies in
jurisdictions with existing controls and measures, could further limit our net revenue and results. Decreases in third‑party reimbursement for our products or a
decision by a third‑party payor to not cover our products could reduce physician usage of the products and have a material adverse effect on our sales, results
of operations and financial condition.

38

 
The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (“MMA”) established the Medicare Part D program to provide a voluntary
prescription drug benefit to Medicare beneficiaries. Under Part D, Medicare beneficiaries may enroll in prescription drug plans offered by private entities that
provide coverage of outpatient prescription drugs. Unlike Medicare Part A and B, Part D coverage is not standardized. Part D prescription drug plan sponsors
are not required to pay for all covered Part D drugs, and each drug plan can develop its own drug formulary that identifies which drugs it will cover and at
what  tier  or  level.  However,  Part  D  prescription  drug  formularies  must  include  drugs  within  each  therapeutic  category  and  class  of  covered  Part  D  drugs,
though not necessarily all the drugs in each category or class. Any formulary used by a Part D prescription drug plan must be developed and reviewed by a
pharmacy  and  therapeutic  committee.  Government  payment  for  some  of  the  costs  of  prescription  drugs  may  increase  demand  for  products  for  which  we
receive marketing approval. However, any negotiated prices for our products covered by a Part D prescription drug plan will likely be lower than the prices
we  might  otherwise  obtain.  Moreover,  while  the  MMA  applies  only  to  drug  benefits  for  Medicare  beneficiaries,  private  payors  often  follow  Medicare
coverage policy and payment limitations in setting their own payment rates. Any reduction in payment that results from the MMA may result in a similar
reduction in payments from non‑governmental payors.

The American Recovery and Reinvestment Act of 2009 provides funding for the federal government to compare the effectiveness of different treatments for
the same illness. The plan for the research was published in 2012 by the Department of Health and Human Services, the Agency for Healthcare Research and
Quality and the National Institutes for Health, and periodic reports on the status of the research and related expenditures will be made to Congress.

It is likely that our product candidates, once approved, will have to be administered by a health care provider. Under currently applicable U.S. law, certain
products not usually self-administered (including injectable drugs) may be eligible for coverage under Medicare Part B. As a condition of receiving Medicare
Part  B  reimbursement,  the  manufacturer  of  the  therapy  is  required  to  participate  in  other  government  healthcare  programs,  including  the  Medicaid  Drug
Rebate  Program  and  the  340B  Drug  Pricing  Program,  both  of  which  require  the  manufacturer  to  provide  rebated  pricing  under  certain  conditions.  For
example, the Medicaid Drug Rebate Program requires pharmaceutical manufacturers to have a national rebate agreement with the federal government as a
condition for states to receive federal matching funds for the manufacturer’s outpatient drugs furnished to Medicaid patients. Under the 340B Drug Pricing
Program,  the  manufacturer  must  extend  discounts  to  program  eligible  entities,  which  generally  are  federally  funded  clinics  and  hospitals  that  serve  large
numbers of low-income and uninsured patients.

In addition, in some foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing
drug pricing vary widely from country to country. For example, the EU provides options for its member states to restrict the range of medicinal products for
which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. A member state may
approve a specific price for the medicinal product, or it may instead adopt a system of direct or indirect controls on the profitability of the company placing
the  medicinal  product  on  the  market.  There  can  be  no  assurance  that  any  country  that  has  price  controls  or  reimbursement  limitations  for  pharmaceutical
products will allow favorable reimbursement and pricing arrangements for any of our products. Historically, products launched in the EU do not follow price
structures of the U.S. and generally prices tend to be significantly lower.

Healthcare Reform

In  the  U.S.  and  some  foreign  jurisdictions,  there  have  been,  and  likely  will  continue  to  be,  a  number  of  legislative  and  regulatory  changes  and  proposed
changes regarding the healthcare system directed at broadening the availability of healthcare, improving the quality of healthcare, and containing or lowering
the cost of healthcare.

39

 
For example, in March 2010, the ACA was enacted in the U.S. The ACA includes measures that have significantly changed, and are expected to continue to
significantly change, the way healthcare is financed by both governmental and private insurers. Among the provisions of the ACA of greatest importance to
the pharmaceutical industry are that the ACA:

•

•

•

•

•

•

•

•

•

subjects biological products to potential competition by biosimilars;

made several changes to the Medicaid Drug Rebate Program, including increasing pharmaceutical manufacturers’ rebate liability by raising
the minimum basic Medicaid rebate on most branded prescription drugs to 23.1% of average manufacturer price (“AMP”), and adding a new
rebate calculation for “line extensions” (i.e., new formulations, such as extended release formulations) of solid oral dosage forms of branded
products, as well as potentially impacting their rebate liability by modifying the statutory definition of AMP;

imposed a requirement on manufacturers of branded drugs to provide a 50% (increased to 70% on January 1, 2019 pursuant to subsequent
legislation) point‑of‑sale discount off the negotiated price of branded drugs dispensed to Medicare Part D beneficiaries in the coverage gap
(i.e., “donut hole”) as a condition for a manufacturer’s outpatient drugs being covered under Medicare Part D;

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

expanded the entities eligible for discounts under the 340B Drug Discount Program;

established a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs
that are inhaled, infused, instilled, implanted, or injected;

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

imposed new reporting requirements on drug manufacturers for payments made to physicians and teaching hospitals, as well as ownership
and  investment  interests  held  by  physicians  and  their  immediate  family  members.  Failure  to  submit  required  information  may  result  in
significant civil monetary penalties for all payments, transfers of value or ownership or investment interests that are not timely, accurately
and completely reported in an annual submission; and

established  a  new  Patient‑Centered  Outcomes  Research  Institute  to  oversee,  identify  priorities  in,  and  conduct  comparative  clinical
effectiveness research, along with funding for such research. The research conducted by the Patient‑Centered Outcomes Research Institute
may  affect  the  market  for  certain  pharmaceutical  products.  The  ACA  established  the  Center  for  Medicare  and  Medicaid  Innovation
(“CMMI”)  within  CMS  to  test  innovative  payment  and  service  delivery  models  to  lower  Medicare  and  Medicaid  spending,  potentially
including prescription drug spending. Funding was allocated to support the mission of CMMI through 2019. Pursuant to the Fiscal Year 2020
budget, CMMI will receive funding for 10 more years.

Congress also could consider additional legislation to repeal, replace, or further modify elements of the ACA. Thus, the full impact of the ACA, or any law
replacing elements of it, and the political uncertainty regarding any repeal and replacement on the ACA, on our business remains unclear.

Additionally, there have been a number of proposed regulatory actions and legislative recommendations aimed at lowering prescription drug prices. In May
2019, CMS issued a final rule to allow Medicare Advantage Plans the option to use step therapy, a type of prior authorization, for Part B drugs. This final rule
codified CMS’s policy change that was effective January 1, 2019.

We cannot predict what healthcare reform initiatives may be adopted in the future. Further federal, state and foreign legislative and regulatory developments
are likely, and we expect ongoing initiatives to increase pressure on drug pricing. Such reforms could have an adverse effect on anticipated revenues from
product candidates and may affect our overall financial condition and ability to develop product candidates.

Risk Factors

Investing in our common stock involves a high degree of risk. Careful consideration should be given to the following risk factors, in addition to the other
information  set  forth  in  this  Annual  Report  on  Form  10-K  for  the  year  ended  December  31,  2019  and  in  other  documents  that  we  file  with  the  SEC,  in
evaluating  us  and  our  business.  If  any  of  the  following  risks  and  uncertainties  actually  occurs,  our  business,  prospects,  financial  condition  and  results  of
operations could be materially and adversely affected. The risks described below are not intended to be exhaustive and are not the only risks facing us. New
risk factors can emerge from time to time, and it is not possible to predict the impact that any factor or combination of factors may have on our business,
prospects, financial condition and results of operations.

Risks Related to the Discovery, Development, Manufacturing and Commercialization of Product Candidates

CRISPR/Cas9 genome editing technology is not yet clinically validated for human therapeutic use. The approaches we are taking to discover and develop
novel  therapeutics  using  CRISPR/Cas9  systems  are  unproven  and  may  never  lead  to  marketable  products.  If  we  are  unable  to  develop  viable  product
candidates, achieve regulatory approval for any such product candidate or market and sell any product candidates, we may never achieve profitability.

We  are  focused  on  developing  curative  medicines  utilizing  the  CRISPR/Cas9  genome  editing  technology,  including  in  vivo  therapies  and  engineered  cell
therapies. Although there have been significant advances in recent years in the fields of gene therapy, which typically involves introducing a copy of a gene
into a patient’s cells, and genome editing in recent years, in vivo CRISPR-based genome editing technologies are relatively new, and their therapeutic utility is
largely  unproven.  In  addition,  even  though  cell  therapy  products  have  been  developed  and  received  regulatory  approval  in  key  jurisdictions,  such  as  the
United States (“U.S.”) and European Union (“EU”), no genome editing in vivo therapy or genome-edited engineered cell therapy has been approved, and the
potential to successfully obtain approval remains unproven.

41

 
 
The CRISPR/Cas9 therapies, whether in vivo or engineered cell therapies, that we intend to develop have not yet been clinically tested by us, and we are not
aware  of  any  clinical  trials  for  safety  or  efficacy  having  been  completed  by  third  parties  involving  these  CRISPR/Cas9-based  therapies.  The  scientific
evidence to support the feasibility of developing in vivo products or engineered cell therapies based on the CRISPR/Cas9 technology is both preliminary and
limited. Successful development of products by us will require solving a number of issues, including developing or obtaining technologies to safely deliver a
therapeutic  agent  into  target  cells  within  the  human  body  or  engineer  human  cells  while  outside  of  the  body  such  that  the  modified  cells  can  have  a
therapeutic effect when delivered to the patient, optimizing the efficacy and specificity of such products, and ensuring the therapeutic selectivity, efficacy,
potency, purity and safety of such products. There can be no assurance we will be successful in solving any or all of these issues.

We have principally concentrated our research efforts to date on bringing CRISPR/Cas9-based therapeutics to the clinic for various initial indications, and our
future success is highly dependent on the successful development of CRISPR-based genome editing technologies, cellular delivery methods and therapeutic
applications for these indications. These indications are the principal focus of our on-going development efforts, and we may decide to alter or abandon these
programs as new data become available and we gain experience in developing CRISPR/Cas9-based therapeutics. We cannot be sure that our CRISPR/Cas9
efforts and technologies will yield satisfactory products that are safe and effective, sufficiently pure or potent, manufacturable, scalable or profitable in our
selected indications or any other indication we pursue. We cannot guarantee that progress or success in developing any particular CRISPR/Cas9 therapeutic
product will translate to other CRISPR/Cas9 products.

Public  perception  and  related  media  coverage  of  potential  therapy-related  efficacy  or  safety  issues,  including  adoption  of  new  therapeutics  or  novel
approaches  to  treatment,  as  well  as  ethical  concerns  related  specifically  to  genome  editing  and  CRISPR/Cas9,  may  adversely  influence  the  willingness  of
subjects  to  participate  in  clinical  trials,  or  if  any  therapeutic  is  approved,  of  physicians  and  patients  to  accept  these  novel  and  personalized  treatments.
Physicians, health care providers and third-party payors often are slow to adopt new products, technologies and treatment practices, particularly those that
may also require additional upfront costs and training. Physicians may not be willing to undergo training to adopt these novel and potentially personalized
therapies, may decide the particular therapy is too complex or potentially risky to adopt without appropriate training, and may choose not to administer the
therapy. Further, due to health conditions, genetic profile or other reasons, certain patients may not be candidates for the therapies. In addition, responses by
the U.S., state or foreign governments to negative public perception, ethical concerns or financial considerations may result in new legislation, regulations, or
medical  standards  that  could  limit  our  ability  to  develop  or  commercialize  any  product  candidates,  obtain  or  maintain  regulatory  approval  or  otherwise
achieve profitability. Based on these and other factors, health care providers and payors may decide that the benefits of these new therapies do not or will not
outweigh their costs.

Our ability to generate product revenue is dependent on the success of our application of CRISPR/Cas9 technology for human therapeutic use, which is
at  an  early  stage  of  development  and  will  require  significant  additional  discovery  efforts,  preclinical  testing  and  clinical  studies  and  manufacturing
capabilities,  as  well  as  applicable  regulatory  guidance  regarding  preclinical  testing  and  clinical  studies  from  the  U.S.  Food  and  Drug  Administration
(“FDA”) and other regulatory authorities, before we can seek regulatory approval and begin commercial sales of any potential product candidates.

Our ability to generate product revenue is highly dependent on our ability to obtain regulatory approval of and successfully commercialize one or more of our
product candidates. Any product candidates we discover will require preclinical and clinical activities and studies, regulatory review and approval in each
jurisdiction  in  which  we  intend  to  market  the  products,  substantial  investment,  establishing  manufacturing  capabilities,  access  to  sufficient  commercial
manufacturing capacity and significant marketing efforts before we can generate any revenue from product sales. Before obtaining marketing approval from
regulatory authorities for the sale of a product candidate, we must conduct extensive clinical trials to demonstrate the safety, purity and potency, as well as the
efficacy, of the product candidates in humans. We cannot be certain that we will be successful on any of these endeavors, or that any of our product candidates
will be successful in clinical trials and, even if successful, that we will receive regulatory approval.

42

 
Our approach to developing therapies centers on using the CRISPR/Cas9 technology to alter, introduce or remove genetic information in vivo to treat various
disorders, or to engineer human cells ex vivo to create therapeutic cells that can be introduced into the human body to address the underlying disease. Because
these  are  new  therapeutic  approaches,  discovering,  developing,  manufacturing  and  commercializing  our  product  candidates  subject  us  to  a  number  of
challenges, including:

•

•

•

•

•

•

•

•

obtaining  regulatory  approval  from  the  FDA  and  other  regulatory  authorities  that  have  very  limited  or  no  experience  with  the  clinical
development  of  CRISPR/Cas9  therapeutics,  and  which  may  require  additional  significant  testing  or  data  compared  to  more  traditional
therapies;

seeking  and  obtaining  regulatory  approval  from  the  FDA  and  other  regulatory  authorities  in  light  of  no  formal  regulatory  guidance  for
CRISPR/Cas9-based  in  vivo  therapeutics,  including  preclinical  and  clinical  requirements  for  clearance  of  an  Investigational  New  Drug
application (“IND”) and, as appropriate thereafter, a Biologics License Application (“BLA”), or corresponding applications outside the U.S.;

educating medical personnel, including clinical investigators, and patients regarding the potential benefits and side effect profile of each of
our product candidates;

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

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

establishing process development and manufacturing capabilities that can produce sufficient clinical and, if approved, commercial quantities
of product candidates in accordance with the FDA and other relevant regulatory agencies’ requirements;

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

establishing sales and marketing capabilities in anticipation of, and after obtaining, any regulatory approval to gain market authorization.

Additionally,  because  our  in  vivo  technology  potentially  involves  genome  editing  across  multiple  cell  and  tissue  types,  we  are  subject  to  many  of  the
challenges and risks that other genome editing therapeutics and gene therapies face, including:

•

•

•

•

•

regulatory  guidance  regarding  the  requirements  governing  gene  and  genome  editing  therapy  products  have  changed  and  may  continue  to
change in the future. To date, only a limited number of products that involve in vivo gene transfer have been approved globally;

improper  modulation  of  a  gene  sequence,  including  insertion  of  a  sequence  into  a  patient’s  chromosome,  could  lead  to  cancer,  other
aberrantly functioning cells or other diseases, including death;

transient expression of the Cas9 protein within patients’ cells could lead to patients having an immunological reaction towards those cells,
which could be severe or life-threatening;

corrective expression of a missing protein in patients’ cells could result in the protein being recognized as foreign, and lead to a sustained
immunological reaction against the expressed protein or expressing cells, which could be severe or life-threatening; and

regulatory agencies may require extended follow-up observation periods of patients who receive treatment using genome editing products,
including  for  example  the  FDA’s  recommended  15-year  follow-up  observation  period  for  these  patients,  and  we  will  need  to  adopt  such
observation periods for our product candidates if required by the relevant regulatory agency, which could vary by country or region.

43

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Further, because our ex vivo product  candidates  involve  editing  human  cells  and  then  delivering  modified  cells  to  patients,  we  are  subject  to  many  of  the
challenges and risks that engineered cell therapies face. For example, clinical trials using engineered cell-based gene therapies may require unique products to
be created for each patient and such individualistic manufacturing may be both inefficient and cost-prohibitive.

To date, only a few human clinical trials utilizing either in vivo or ex vivo CRISPR/Cas9-based therapeutics have been authorized in the U.S. and EU member
states.  Further,  only  a  limited  number  of  human  clinical  trials  for  in  vivo  therapies  or  engineered  cell  therapies  developed  using  other  genome-editing
technologies have been authorized by the FDA in the U.S. or by the relevant regulatory agencies in the EU member states. There is no certainty that the FDA
or the EMA will apply to CRISPR/Cas9 product candidates the same regulatory pathway and requirements it is applying to other in vivo therapies or ex vivo
engineered therapeutics; and the FDA and other regulatory authorities have not yet provided specific written guidance regarding preclinical or clinical studies
or  regulatory  approval  for  either  in  vivo  or ex vivo genome  editing-based  therapeutics.  In  addition,  if  any  product  candidates  encounter  safety  or  efficacy
problems, development delays, regulatory issues or other problems, our development plans and business could be significantly harmed. Further, competitors
that are developing in vivo or ex vivo products with similar technology may experience problems with their product candidates or programs that could in turn
cause us to identify problems with our product candidates and programs that would potentially harm our business.

Also, uncertainty exists regarding the future scope and effect of the FDA’s application of its regulatory framework to CRISPR/Cas9 therapies, in particular
relating to the review and approval of human therapeutic products because the current U.S. administration and federal legislators have publicly declared their
intention to modify the current legal framework governing the FDA. Any such changes to the FDA requirements could impact our ability to obtain approval
for our products or sell them profitably. Also, upon exiting the EU, the United Kingdom may enact legislation related to the approval and oversight of human
therapeutics in that nation. Until any such legislation is enacted, we will be uncertain as to its effects on our business, including our ability to seek and obtain
approval for our products in the United Kingdom.

Results,  including  positive  results,  from  our  initial  preclinical  activities  and  studies  are  not  necessarily  predictive  of  our  other  ongoing  and  future
preclinical and clinical studies, and they do not guarantee or indicate the likelihood of approval of any potential product candidate by the FDA, EMA or
any other regulatory agency. If we cannot replicate the positive results from any of our preclinical or clinical activities and studies, we may be unable to
successfully develop, obtain regulatory approval for and commercialize any potential product candidate.

There  is  a  high  failure  rate,  as  well  as  potential  substantial  and  unanticipated  delays,  for  product  candidates  progressing  through  preclinical  and  clinical
studies. Even if we are able to successfully complete our ongoing and future preclinical and clinical activities and studies for any potential product candidate,
we may not be able to replicate, or may have to engage in significant efforts and resource and time investments to replicate, any positive results from these or
any other studies in any of our future preclinical and clinical trials, and they do not guarantee approval of any potential product candidate by the FDA, EMA
or  any  other  necessary  regulatory  authorities  in  a  timely  manner  or  at  all.  Companies  in  the  pharmaceutical  and  biotechnology  industries  have  commonly
suffered significant setbacks or delays in clinical studies after achieving positive results in early stage development, and we cannot be certain that we will not
face  similar  setbacks.  These  setbacks  have  been  caused  by,  among  other  things,  preclinical  findings  made  before,  during  and  after  clinical  studies  were
underway, or observations regarding the lack of safety or efficacy made in clinical studies, which could include new or previously unreported adverse events.
In addition, regulatory delays or rejections may be encountered as a result of many factors, including changes in the relevant laws, regulations or regulatory
policy during the period of product development.

Moreover,  preclinical  and  clinical  data  are  often  susceptible  to  varying  interpretations  and  analyses,  and  many  companies  that  believed  their  product
candidates performed satisfactorily in such studies nonetheless failed to obtain FDA, EMA or other necessary regulatory agency approval. If we fail to obtain
results  in  our  on-going,  planned  and  future  preclinical  and  clinical  activities  and  studies  sufficient  to  meet  the  requirements  of  the  relevant  regulatory
agencies, the development timeline and regulatory approval and commercialization prospects for any potential product candidate, and, correspondingly, our
business and financial prospects, would be materially adversely affected.

Negative public opinion and increased regulatory scrutiny of CRISPR/Cas9 use, genome editing or gene therapy generally may damage public perception
of the safety of any product candidates that we develop and adversely affect our ability to conduct our business or obtain regulatory approvals for such
product candidates.

Gene therapy in general, and genome editing in particular, remain novel technologies, with only a limited number of gene therapy products approved to date
in the U.S. and EU. Public perception may be influenced by claims that gene therapy or genome editing, including the use of CRISPR/Cas9, is unsafe or
unethical, or carries an undue risk of side effects, such as improper insertion of a gene sequence into a patient’s chromosome could lead to cancer, and gene
therapy or genome editing 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 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 more familiar and for which greater clinical data may be available. In addition, responses by the U.S.,
state  or  foreign  governments  to  negative  public  perception  or  ethical  concerns  may  result  in  new  legislation  or  regulations  that  could  limit  our  ability  to
develop  or  commercialize  any  product  candidates,  obtain  or  maintain  regulatory  approval  or  otherwise  achieve  profitability.  More  restrictive  statutory
regimes,  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. Serious adverse events such as these
in our clinical trials, or other clinical trials involving gene therapy or genome editing 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  of  our  product  candidates,  stricter  labeling  requirements  for  those  product  candidates  that  are  approved  and  a
decrease in demand for any such product candidate. In addition, the use of the technology by third parties in areas that are not being pursued by us, such as for
targeting  and  editing  of  embryonic  cells,  could  adversely  impact  public  and  governmental  perceptions  regarding  the  ethics  and  risks  of  the  CRISPR/Cas9
technology  and  lead  to  social  or  legal  changes  that  could  limit  our  ability  to  apply  the  technology  to  develop  human  therapies  addressing  disease.  For
example,  reports  of  the  use  of  CRISPR/Cas9  in  China  and  Russia  to  edit  embryos  in  utero  has  generated  and  may  continue  to  create  negative  public
perception about the use of the technology in humans. Negative public and governmental perception of the technology, or additional governmental regulation
of our technologies, could also adversely affect our stock price or our ability to enter into revenue generating collaborations or obtain additional funding from
the public markets.

Inconclusive results, lack of efficacy, adverse events or additional safety concerns in clinical trials that we or others conduct may impede the regulatory
approval process or overall market acceptance of our future product candidates.

Therapeutic  applications  of  genome  editing  technologies,  and  CRISPR/Cas9  in  particular,  for  both  in vivo  products  and  in  engineered  cell  therapies,  are
unproven and must undergo rigorous clinical trials and regulatory review before receiving marketing authorization. If the results of our clinical studies or
those of any other third parties, including with respect to genome editing technology or engineered cell therapies, are inconclusive, fail to show efficacy or if
such clinical trials give rise to safety concerns or adverse events, we may:

•

•

•

•

•

•

be delayed in obtaining marketing approval for our future 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 the addition of labeling statements, such as warnings or contraindications, or other types of regulatory restrictions or scrutiny;

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

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

45

 
 
 
 
 
 
 
•

•

•

have  regulatory  authorities  modify  or  withdraw  their  legal  requirements  or  written  guidance,  if  any,  regarding  the  applicable  regulatory
approval  pathway  or  any  approval  of  the  product  in  question,  or  impose  restrictions  on  its  distribution  in  the  form  of  a  modified  Risk
Evaluation and Mitigation Strategy (“REMS”);

be sued; or

experience damage to our reputation.

Additionally, our future product candidates could potentially cause other adverse events that have not yet been predicted and the potentially permanent nature
of genome editing effects, including CRISPR/Cas9’s effects, on genes or novel cell therapies in the organs of the human body may make these adverse events
irreversible. The inclusion of critically ill patients in our clinical studies or those of our competitors may result in deaths or other adverse medical events,
including those due to other therapies or medications that such patients may be using. Any of these events could prevent us from achieving or maintaining
regulatory approval or market acceptance of our future product candidates and impair our ability to achieve profitability.

Clinical  development  involves  a  lengthy  and  expensive  process,  with  an  uncertain  outcome.  We  may  incur  additional  costs  or  experience  delays  in
completing, or ultimately be unable to complete, the development and commercialization of any product candidates.

All  of  our  lead  programs  are  still  in  the  discovery  or  preclinical  stage,  and  their  risk  of  failure  is  high.  It  is  impossible  to  predict  when  or  if  any  of  our
programs will prove effective and safe in humans or will receive regulatory approval. Before obtaining marketing approval from regulatory authorities for the
sale of any product candidate, we must complete preclinical development and then conduct extensive clinical trials to demonstrate the safety and efficacy of
any  of  our  future  product  candidates  in  humans.  Preclinical  and  clinical  testing  is  expensive,  difficult  to  design  and  implement,  can  take  many  years  to
complete and is uncertain as to outcome. We may be unable to establish clinical endpoints that applicable regulatory authorities would consider clinically
meaningful, and a clinical trial can fail at any stage of testing. The outcome of preclinical testing and early clinical trials may not be predictive of the success
of later clinical trials, and interim results of a clinical trial do not necessarily predict final results. Moreover, preclinical and clinical data are often susceptible
to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in preclinical studies and
clinical trials have nonetheless failed to obtain marketing approval of their products.

Successful completion of clinical trials is a prerequisite to submitting a BLA to the FDA, a Marketing Authorization Application to the EMA and similar
filings to comparable foreign regulatory authorities, for each product candidate and, consequently, the ultimate approval and commercial marketing of any
product candidates. We do not know whether any of our clinical trials will begin or be completed on schedule, if at all.

We may experience delays in completing our preclinical studies and initiating or completing clinical trials. We also may experience numerous unforeseen
events during, or as a result of, any future clinical trials that we could conduct, which could delay or prevent our ability to receive marketing approval or
commercialize our product candidates, including:

•

•

•

•

regulators, institutional review boards (“IRBs”) or ethics committees may not authorize us or our investigators to commence a clinical trial or
conduct a clinical trial at a prospective trial site;

we may experience delays in reaching, or fail to reach, agreement on acceptable terms with prospective trial sites and prospective contract
research  organizations  (“CROs”),  the  terms  of  which  can  be  subject  to  extensive  negotiation  and  may  vary  significantly  among  different
CROs and trial sites;

clinical trials of any product candidates may fail to show safety or efficacy, produce negative or inconclusive results and we may decide, or
regulators  may  require  us,  to  conduct  additional  preclinical  studies  or  clinical  trials  or  we  may  decide  to  abandon  product  development
programs;

the  number  of  patients  required  for  clinical  trials  of  any  product  candidates  may  be  larger  than  we  anticipate,  enrollment  in  these  clinical
trials may be lower than required by the regulatory agencies or slower than we anticipate, or participants may drop out of these clinical trials
or fail to return for post-treatment follow-up at a higher rate than we anticipate;

46

 
 
 
 
 
 
 
 
•

•

•

•

•

•

•

regulatory agencies may require us to perform more extensive or lengthier clinical testing compared to existing therapeutic modalities;

our third-party contractors may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or
at  all,  or  may  deviate  from  the  clinical  trial  protocol  or  drop  out  of  the  trial,  which  may  require  that  we  add  new  clinical  trial  sites  or
investigators;

we may elect to, or regulators, IRBs or ethics committees may require that we or our investigators, suspend or terminate clinical research or
trials  for  various  reasons,  including  noncompliance  with  regulatory  requirements  or  a  finding  that  the  participants  are  being  exposed  to
unacceptable health risks;

the cost of preclinical studies and clinical trials of any product candidates may be greater than we anticipate;

the  supply  or  quality  of  our  product  candidates  or  other  materials  necessary  to  conduct  clinical  trials  of  our  product  candidates  may  be
insufficient or inadequate, or not available in a reasonable timeframe;

our product candidates may have undesirable side effects or other unexpected characteristics, causing us or our investigators, regulators, IRBs
or  ethics  committees  to  suspend  or  terminate  the  trials,  or  reports  may  arise  from  preclinical  or  clinical  testing  of  other  gene  therapies  or
genome editing-based therapies that raise safety or efficacy concerns about our product candidates; and

the  FDA  or  other  regulatory  authorities  may  require  us  to  submit  additional  data,  such  as  long-term  toxicology  studies,  or  impose  other
requirements before permitting us to initiate or rely on a clinical trial.

We could also encounter delays if a clinical trial is suspended or terminated by us, the IRBs of the institutions in which such trials are being conducted, the
Data  Safety  Monitoring  Board  (“DSMB”)  for  such  trial  or  the  FDA  or  other  regulatory  authorities.  Such  authorities  may  impose  such  a  suspension  or
termination due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols,
inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, manufacturing or
quality control issues, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a product or treatment, failure to establish
or achieve clinically meaningful trial endpoints, changes in governmental regulations or administrative actions or lack of adequate funding to continue the
clinical trial. Many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of
regulatory  approval  of  our  product  candidates.  Further,  the  FDA  or  other  regulatory  authorities  may  disagree  with  our  clinical  trial  design  and  our
interpretation of data from clinical trials or may change the requirements for approval even after they have reviewed and commented on the design for our
clinical trials.

Our  product  development  costs  will  increase  if  we  experience  delays  in  clinical  testing  or  marketing  approvals.  We  do  not  know  whether  any  of  our
preclinical studies or clinical trials will begin as planned, will need to be restructured or will be completed on schedule, or at all. Significant preclinical or
clinical trial delays also could shorten any periods during which we may have the exclusive right to commercialize our product candidates and may allow our
competitors to bring products to market before we do, potentially impairing our ability to successfully commercialize our product candidates and harming our
business  and  results  of  operations.  Any  delays  in  our  preclinical  or  future  clinical  development  programs  may  harm  our  business,  financial  condition  and
prospects significantly.

We face significant competition in an environment of rapid technological change. The possibility that our competitors may achieve regulatory approval
before  we  do  or  develop  therapies  that  are  more  advanced  or  effective  than  ours  may  harm  our  business  and  financial  condition  or  our  ability  to
successfully market or commercialize our product candidates.

The  biotechnology  and  pharmaceutical  industries,  including  the  genome  editing  field  and  engineered  cell  therapies,  are  characterized  by  rapidly  changing
technologies, significant competition and a strong emphasis on intellectual property. We face substantial competition from many different sources, including
large  and  specialty  pharmaceutical  and  biotechnology  companies,  academic  research  institutions,  government  agencies  and  public  and  private  research
institutions.

47

 
 
 
 
 
 
 
 
Competitors in our efforts to provide genetic therapies to patients can be grouped into at least three sets based on their product discovery platforms:

•

•

•

genome  editing  companies  focused  on  CRISPR/Cas9  including:  Beam  Therapeutics  Inc.,  Caribou  Biosciences,  Inc.  (“Caribou”),  CRISPR
Therapeutics, Inc., Editas Medicine, Inc., ToolGen, Inc., Tracr Hematology Limited and Verve Therapeutics, Inc.;

other  genome  editing  companies  including:  Allogene  Therapeutics,  Inc.,  bluebird  bio,  Inc.,  Cellectis  S.A.,  Homology  Medicines,  Inc.,
Poseida, Inc., Precision BioSciences, Inc. and Sangamo Therapeutics, Inc.; and

gene therapy companies developing in vivo or ex vivo therapies, such as cell therapies, including: Asklepios Biopharmaceutical, Inc., bluebird
bio, Inc., Cellectis S.A., Bristol Myers Squibb (which acquired Celgene Corporation), Gilead Sciences, Inc. (which acquired Kite Pharma,
Inc.), Novartis A.G., Roche Holding AG (which acquired Spark Therapeutics, Inc.) and Voyager Therapeutics, Inc.

Our  competitors  also  include  companies  that  are  or  will  be  developing  other  genome  editing  methods  as  well  as  small  molecules,  biologics,  in vivo  gene
therapies, engineered cell therapies (both autologous and allogeneic) and nucleic acid-based therapies for the same indications that we are targeting with our
CRISPR/Cas9-based therapeutics.

Any advances in gene therapy, engineered cell therapies or genome editing technology made by a competitor may be used to develop therapies that could
compete against any of our product candidates.

Many  of  these  competitors  have  substantially  greater  research  and  development  capabilities  and  financial,  scientific,  technical,  intellectual  property,
manufacturing, marketing, distribution and other resources than we do, and we may not be able to successfully compete with them.

To  become  and  remain  profitable,  we  must  discover,  develop,  manufacture  and  eventually  commercialize  product  candidates  with  significant  market
potential, which will require us to be successful in a range of challenging activities. These activities can include completing preclinical studies and clinical
trials of product candidates, obtaining marketing approval for product candidates, manufacturing at a sufficient scale, marketing and selling products that are
approved  and  satisfying  any  pre-approval,  approval  and  post-marketing  requirements.  Even  if  we  are  successful  in  selecting  and  developing  any  product
candidates, in order to compete successfully we may need to be first-to-market or demonstrate that our CRISPR/Cas9-based products are superior to therapies
based on the same or different treatment methods. If we are not first-to-market or are unable to demonstrate such superiority, any products for which we are
able to obtain approval may not be commercially successful. Furthermore, in certain jurisdictions, if a competitor has orphan drug status for a product and if
our  product  candidate  is  determined  to  be  contained  within  the  scope  of  a  competitor’s  orphan  drug  exclusivity,  then  approval  of  our  product  for  that
indication or disease could potentially be blocked, for example, for up to seven years in the U.S. and 10 years in the EU.

We may never succeed in any or all of these activities and, even if we do, we may never generate revenues that are significant or large enough to achieve
profitability. If we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and
remain profitable would decrease our value and could impair our ability to raise capital, maintain our research and development efforts, expand our business
or continue our operations.

48

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

We may not be able to initiate or continue clinical trials for any future product candidates if we are unable to locate and enroll a sufficient number of eligible
patients to participate in these trials as required by the FDA or similar regulatory authorities outside the U.S. If patients are unwilling to participate in our
clinical studies because of concerns about, or negative publicity from, adverse events in the genome editing, gene therapy or engineered cell therapy fields,
the novel nature of the CRISPR/Cas9 genome editing technology, the irreversibility of the effects of CRISPR/Cas9 or for other reasons, including competitive
clinical  studies  for  similar  patient  populations,  then  the  timeline  for  recruiting  patients,  conducting  studies  and  obtaining  regulatory  approval  of  potential
products may be delayed. These delays could result in increased costs, delays in advancing our product development, delays in testing the effectiveness of our
technology or termination of the clinical studies altogether. In addition, any patients who would otherwise be eligible for clinical trials that we may hold may
instead enroll in clinical trials of product candidates of our competitors.

Patient enrollment is affected by other factors including:

•

•

•

•

•

•

•

•

•

•

the size, location and nature of the patient population;

the severity of the disease under investigation;

the patient eligibility criteria for the study in question;

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

the design of the clinical trial;

the availability of alternative treatments;

our payments for conducting clinical trials;

the patient referral practices of physicians;

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

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

Our inability to enroll a sufficient number of patients for clinical trials would result in significant delays and could require us to abandon one or more clinical
trials altogether. Enrollment delays in clinical trials may result in increased development costs for any of our potential future product candidates, which would
cause our value to decline and limit our ability to obtain additional financing. Furthermore, we expect to rely on CROs and clinical trial sites to ensure the
proper  and  timely  conduct  of  our  clinical  trials,  and,  while  we  expect  to  enter  into  agreements  governing  their  committed  activities,  we  will  have  limited
influence over their actual performance.

Research and development of biopharmaceutical products is inherently risky. We may not be successful in our efforts to use and enhance our genome
editing technology to create a pipeline of product candidates, establish the necessary manufacturing capabilities, obtain regulatory approval and develop
commercially  successful  products,  or  we  may  expend  our  limited  resources  on  programs  that  do  not  yield  a  successful  product  candidate  and  fail  to
capitalize  on  potential  product  candidates  or  diseases  that  may  be  more  profitable  or  for  which  there  is  a  greater  likelihood  of  success.  If  we  fail  to
develop product candidates, our commercial opportunity, if any, will be limited.

Although we have selected an initial product candidate for clinical development for our transthyretin amyloidosis (“ATTR”) program, we are at an early stage
of development and our technology and approach has not yet led, and may never lead, to any product candidate deemed appropriate for clinical development
by  a  regulatory  agency  or  any  approved  or  commercially  successful  products.  Even  if  we  are  successful  in  building  our  pipeline  of  product  candidates,
completing clinical development, establishing the necessary manufacturing processes and capabilities, obtaining regulatory approvals and commercializing
product candidates will require substantial additional funding and are prone to the risks of failure inherent in therapeutic product development. Investment in
biopharmaceutical  product  development  involves  significant  risk  that  any  potential  product  candidate  will  fail  to  demonstrate  adequate  efficacy  or  an
acceptable safety profile, gain regulatory approval, or become commercially viable.

49

 
 
 
 
 
 
 
 
 
 
 
We cannot provide any assurance that we will be able to successfully advance any product candidates that we discover through the research process. Our
research programs may initially show promise, yet fail to yield product candidates for clinical development or commercialization for many reasons, including
the following:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

our  technology  and  approach  may  not  be  successful  in  identifying  product  candidates  deemed  appropriate  for  clinical  development  and
commercialization;

we  may  not  be  able  or  willing  to  assemble  sufficient  resources  to  acquire  or  discover  product  candidates  for  clinical  development  and
commercialization;

animal or other non-human models for the targeted disease may not be appropriate or available to conduct preclinical testing;

testing in preclinical models may not be predictive of human clinical testing results because species have distinct genomic sequences that
may require the use of species-specific guides and reagents;

our product candidates may not succeed in preclinical or clinical testing;

our planned risk mitigation strategy for selecting our initial indications may fail or we may not be able to efficiently apply learnings from our
initial development programs to future development programs;

progress made in one target or using one editing approach may not translate to any other target or editing approach;

we may be unable to optimize the therapeutic efficiency, specificity, or selectivity of our future product candidates;

our  therapeutic  delivery  systems  may  fail  so  that  even  a  product  candidate  with  therapeutic  activity  might  not  demonstrate  a  clinically
meaningful therapeutic effect;

a  product  candidate  may  not  demonstrate  in  patients  the  biological,  chemical  and  pharmacological  properties  identified  in  laboratory  and
preclinical studies, or they may interact with human biological systems in unforeseen, ineffective or even harmful ways;

a  product  candidate  may  on  further  study  not  replicate  the  results  from  earlier  studies  or  be  shown  to  have  harmful  side  effects  or  other
characteristics that indicate it is unlikely to be effective or otherwise does not meet applicable regulatory criteria;

the therapeutic effect of a product candidate may not be permanent and may diminish over time;

we may not be able to sufficiently control the effect of a product candidate to gain regulatory approval;

a single treatment course may not be sufficient for a cure or therapeutic benefit, and it may take several treatment courses for the product to
be effective;

our product candidates may not be sufficiently well-tolerated for either one-time or repeat treatments necessary for maximum effectiveness;

a well-defined and achievable pathway to regulatory approval may never materialize for a specific product candidate;

competitors may develop alternatives that render our product candidates obsolete, redundant or less attractive;

product candidates we develop may be covered by third-party or other exclusive rights or may not receive desired regulatory exclusivity, and
we may be unable to maintain, expand or protect our intellectual property rights;

the market for a product candidate may change during our program so that the continued development of that product candidate is no longer
reasonable;

50

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

•

•

•

we may be unable to manufacture the product candidates after transferring our manufacturing processes from our research and development
facilities to larger-scale facilities operated by either a contract manufacturing organization (“CMO”) or by us, as well as delays or failure by
our CMOs or us to make any changes to such manufacturing process to meet specifications for the product candidates’ specifications;

a product candidate may not be capable of being produced in clinical and, if approved, commercial quantities at an acceptable cost, or at all;

we  may  be  unable  to  successfully  maintain  existing  collaborations  or  licensing  arrangements  or  enter  into  new  ones  throughout  the
development process as appropriate; and

a product candidate may not be accepted as safe and effective by physicians, patients, hospitals, third-party payors and others in the medical
community.

If any of these events occur, we may be forced to abandon our development efforts for a product candidate, program or programs, or we may not be able to
identify,  discover,  develop,  manufacture  or  commercialize  product  candidates,  which  would  have  a  material  adverse  effect  on  our  business  and  could
potentially cause us to cease operations.

Because we have limited financial and managerial resources, we are initially focused on specific research programs. As a result, we may fail to capitalize on
other viable commercial products or profitable market opportunities, be required to forego or delay pursuit of opportunities with other product candidates or
other  diseases  that  may  later  prove  to  have  greater  commercial  potential,  or  relinquish  valuable  rights  to  such  product  candidates  through  collaboration,
licensing or other royalty arrangements in cases in which it would have been advantageous for us to retain sole development and commercialization rights.
For additional information regarding the factors that will affect our ability to achieve revenue from product sales, see the risk factor entitled “We have never
generated any revenue from product sales and our ability to generate revenue from product sales and become profitable depends significantly on our success
in a number of areas.”

If we do not successfully develop, manufacture and commercialize product candidates based upon our approach, we will not be able to obtain product revenue
in future periods, which likely would result in significant harm to our financial position and adversely affect our stock price. Further, our current focus on
CRISPR/Cas9 technology for developing products as opposed to multiple, more proven technologies for product development increases the risk associated
with our business. If we are not successful in developing a product candidate using CRISPR/Cas9 technology, we may not be able to successfully implement
an alternative product development strategy.

Even if we obtain regulatory approval of any product candidates, such candidates may not gain market acceptance among physicians, patients, hospitals,
third-party payors and others in the medical community.

The use of the CRISPR/Cas9 system as a framework for developing genome editing-based therapies is a recent development and may not become broadly
accepted by physicians, patients, hospitals, third-party payors and others in the medical community. A variety of factors will influence whether our product
candidates are accepted in the market, including, for example:

•

•

•

•

•

•

•

•

the clinical indications for which our product candidates are approved;

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

the incidence and severity of any side effects, including any unintended DNA changes;

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

limitations or warnings contained in the labeling approved by the FDA or other regulatory authorities;

the timing of market introduction of our product candidates;

availability or existence of competitive products;

the cost of treatment in relation to alternative treatments;

51

 
 
 
 
 
 
 
 
 
 
 
 
 
•

•

•

•

•

•

•

•

•

•

the amount of upfront costs or training required for health care providers to administer our product candidates;

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

patients’ ability to access physicians and medical centers capable of delivering any therapies that we develop;

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

the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;

relative convenience and ease of administration, including as compared to alternative treatments and competitive therapies;

any restrictions on the use of our product candidates together with other medications;

interactions of our product candidates with other medicines patients are taking;

potential adverse events for any products developed, or negative interactions with regulatory agencies, by us or others in the gene therapy and
genome editing fields; and

the effectiveness of our sales and marketing efforts and distribution support.

Even  if  our  products  achieve  market  acceptance,  we  may  not  be  able  to  maintain  that  market  acceptance  over  time  if  new  products  or  technologies  are
introduced that are more favorably received than our products, are more cost effective or render our products obsolete. In addition, adverse publicity due to
the ethical and social controversies surrounding the therapeutic in vivo use of CRISPR/Cas9, gene edited modified cells, or other therapeutics mediums, such
as viral vectors that we may use in our clinical trials may limit market acceptance of our product candidates. If our product candidates are approved but fail to
achieve  market  acceptance  among  physicians,  patients,  hospitals,  third-party  payors  or  others  in  the  medical  community,  we  will  not  be  able  to  generate
significant revenue. Our efforts to educate the health care providers, patients and third-party payors about our products may require significant resources and
may never be successful.

If, in the future, we are unable to establish sales, marketing and distribution capabilities or enter into agreements with third parties to sell, market and
distribute products based on our technologies, we may not be successful in commercializing our products if and when any product candidates or therapies
are approved and we may not be able to generate any revenue.

We  do  not  currently  have  a  sales,  marketing  or  distribution  infrastructure  and,  as  a  company,  have  no  experience  in  the  sale,  marketing  or  distribution  of
therapeutic products. To achieve commercial success for any approved product candidate for which we retain sales and marketing responsibilities, we must
build our sales, marketing, managerial and other non-technical capabilities or make arrangements with third parties to perform these services. In the future,
we may choose to build a focused sales and marketing infrastructure to sell, or participate in sales activities with our collaborators for, some of our product
candidates if they are approved.

There are risks involved with both establishing our own sales and marketing capabilities and entering into arrangements with third parties to perform these
services. For example, recruiting and training a sales force is expensive and time consuming and could delay any product launch. If the commercial launch of
a  product  candidate  for  which  we  recruit  a  sales  force  and  establish  marketing  capabilities  is  delayed  or  does  not  occur  for  any  reason,  we  would  have
prematurely  or  unnecessarily  incurred  these  commercialization  expenses.  This  may  be  costly  and  our  investment  would  be  lost  if  we  cannot  retain  or
reposition our sales and marketing personnel.

Factors that may inhibit our efforts to commercialize our product candidates on our own include:

•

•

•

•

•

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

the inability of sales personnel to obtain access to physicians or persuade adequate numbers of physicians to prescribe any future product
candidates that we may develop;

the lack of complementary treatments to be offered by sales personnel, which may put us at a competitive disadvantage relative to companies
with more extensive product lines;

the location of patients in need of our product candidates and the treating physicians who may prescribe the products; and

unforeseen costs and expenses, as well as legal and regulatory requirements, associated with creating and operating a sales and marketing
organization.

If we enter into arrangements with third parties to perform sales, marketing and distribution services, our product revenue or the profitability to us from these
revenue  streams  is  likely  to  be  lower  than  if  we  were  to  market  and  sell  any  product  candidates  that  we  develop  ourselves.  In  addition,  we  may  not  be
successful in entering into arrangements with third parties to sell and market our product candidates or may be unable to do so on terms that are favorable to
us. We likely will have little control over such third parties and any of them may fail to devote the necessary resources and attention to sell and market our
product candidates effectively. If we do not establish sales, marketing and distribution capabilities successfully, either on our own or in collaboration with
third  parties,  we  may  not  be  successful  in  commercializing  our  product  candidates.  Further,  our  business,  results  of  operations,  financial  condition  and
prospects will be materially adversely affected.

Coverage  and  reimbursement  may  be  limited  or  unavailable  in  certain  market  segments  for  our  product  candidates,  if  approved,  which  could  make  it
difficult for us to sell any product candidates or therapies profitably.

The success of our product candidates, if approved, depends on the availability of adequate coverage and reimbursement from third-party payors, including
government  agencies.  There  is  significant  uncertainty  related  to  the  insurance  coverage  and  reimbursement  of  newly  approved  products,  particularly  gene
editing and engineered cell products. Coverage may be more limited than the purposes for which a therapeutic is approved by the FDA or comparable foreign
regulatory authorities. In addition, because our product candidates represent new approaches to the treatment of genetic-based diseases, we cannot be sure that
coverage  and  reimbursement  will  be  available  for,  or  accurately  estimate  the  potential  revenue  from,  our  product  candidates  or  assure  that  coverage  and
reimbursement will be available for any product that we may develop.

Patients who are provided medical treatment for their conditions generally rely on third-party payors to reimburse all or part of the costs associated with their
treatment.  Adequate  coverage  and  reimbursement  from  governmental  healthcare  programs,  such  as  Medicare  and  Medicaid,  and  commercial  payors  are
critical to new product acceptance.

Government authorities and other third-party payors, such as private health insurers and health maintenance organizations, decide which drugs and treatments
they  will  cover  and  the  amount  of  reimbursement.  In  the  U.S.,  the  principal  decisions  about  reimbursement  for  new  medicines  are  typically  made  by  the
Centers for Medicare & Medicaid Services (“CMS”), an agency within the U.S. Department of Health and Human Services. CMS decides whether and to
what extent a new medicine will be covered and reimbursed under Medicare, and private payors often follow CMS’ coverage decisions.

Coverage  and  reimbursement  by  a  third-party  payor  may  depend  upon  a  number  of  factors,  including  the  third-party  payor’s  determination  that  use  of  a
product is:

•

•

•

•

•

a covered benefit under its health plan;

safe, effective and medically necessary;

appropriate for the specific patient;

cost-effective; and

neither experimental nor investigational.

53

 
 
 
 
 
 
 
 
 
 
 
In  the  U.S.,  no  uniform  policy  of  coverage  and  reimbursement  for  products  exists  among  third-party  payors.  As  a  result,  obtaining  coverage  and
reimbursement approval of a product from a government or other third-party payor is a time-consuming and costly process that could require us to provide to
each payor supporting scientific, clinical and cost-effectiveness data for the use of our products on a payor-by-payor basis, with no assurance that coverage
and  adequate  reimbursement  will  be  obtained.  Even  if  we  obtain  coverage  for  a  given  product,  the  resulting  reimbursement  payment  rates  might  not  be
adequate for us to maintain pricing sufficient to achieve or sustain profitability or may require co-payments that patients find unacceptably high. Additionally,
third-party payors may not cover, or provide adequate reimbursement for, long-term follow-up evaluations required following the use of our gene-modifying
products. Patients are unlikely to use our product candidates unless coverage is provided and reimbursement is adequate to cover a significant portion of the
cost  of  our  product  candidates.  Because  our  product  candidates  may  have  a  higher  cost  of  goods  than  conventional  therapies,  and  may  require  long-term
follow up evaluations, the risk that coverage and reimbursement rates may be inadequate for us to achieve profitability may be greater. There is significant
uncertainty related to insurance coverage and reimbursement of newly approved products. It is difficult to predict at this time what third-party payors will
decide with respect to the coverage and reimbursement for our product candidates.

Moreover, increasing efforts by governmental and third-party payors in the U.S. and abroad to cap or reduce healthcare costs may cause such organizations to
limit both coverage and the level of reimbursement for newly approved products and, as a result, they may not cover or provide adequate payment for our
product candidates. We expect to experience pricing pressures in connection with the sale of any of our product candidates due to the trend toward managed
healthcare, the increasing influence of health maintenance organizations, cost containment initiatives and additional legislative changes.

We  intend  to  seek  approval  to  market  our  product  candidates  in  both  the  U.S.  and  in  selected  foreign  jurisdictions.  If  we  obtain  approval  in  one  or  more
foreign jurisdictions for our product candidates, we will be subject to rules and regulations in those jurisdictions. In some foreign countries, particularly those
in  the  EU  and  the  United  Kingdom,  the  pricing  of  pharmaceutical  products,  including  biologics,  is  subject  to  governmental  control  and  other  market
regulations  which  could  put  pressure  on  the  pricing  and  usage  of  our  product  candidates.  In  these  countries,  pricing  negotiations  with  governmental
authorities  can  take  considerable  time  after  obtaining  marketing  approval  of  a  product  candidate.  In  addition,  market  acceptance  and  sales  of  our  product
candidates will depend significantly on the availability of adequate coverage and reimbursement from third-party payors for our product candidates and may
be affected by existing and future health care reform measures.

In vivo genome editing products and ex vivo engineered cell therapies based on CRISPR-Cas9 genome editing technology are novel and may be complex
and difficult to manufacture. We could experience manufacturing problems that result in delays in the development, approval or commercialization of
our product candidates or otherwise harm our business.

The manufacturing process used to produce CRISPR/Cas9-based in vivo and engineered cell therapy product candidates may be complex, as they are novel
and have not been validated for clinical and commercial production and may require components that are difficult to obtain or manufacture at the necessary
quantities and in accordance with regulatory requirements. Several factors could cause production interruptions, including equipment malfunctions; facility
unavailability  or  contamination;  raw  material  cost,  shortages  or  contamination;  natural  disasters;  disruption  in  utility  services;  human  error;  insufficient
personnel; inability to meet legal or regulatory requirements; or disruptions in the operations of our suppliers.

Our product candidates that are regulated as biologics, will require processing steps that are more complex than those required for most small molecule drugs.
Moreover,  unlike  small  molecules,  the  physical  and  chemical  properties  of  a  complex  product  such  as  ours  generally  cannot  be  fully  characterized.  As  a
result,  assays  of  the  finished  product  or  relevant  components  may  not  be  sufficient  to  ensure  that  the  product  will  perform  in  the  intended  manner.
Accordingly, we will employ multiple steps to control the manufacturing process to ensure that the process works and the product candidate is made strictly
and consistently in compliance with the process. Problems with the manufacturing process, even minor deviations from the normal process, could result in
product defects or manufacturing failures that result in lot failures, product recalls, product liability claims and litigation, insufficient inventory or production
interruption.  We  may  encounter  problems  achieving  adequate  quantities  and  quality  of  clinical  grade  materials  that  meet  FDA,  EMA  or  other  applicable
standards or specifications with consistent and acceptable production yields and costs.

54

 
In addition, the FDA, the EMA and other foreign regulatory authorities may require us to submit samples of any lot of any approved product together with the
protocols  showing  the  results  of  applicable  tests  at  any  time.  Under  some  circumstances,  the  FDA,  the  EMA  or  other  foreign  regulatory  authorities  may
require that we not distribute a lot until the relevant agency authorizes its release. Slight deviations in the manufacturing process, including those affecting
quality attributes and stability, may result in unacceptable changes in the product that could result in lot failures, product recalls or production interruption.
Lot failures, product recalls or production interruption could cause us to delay product launches or clinical trials, which could be costly to us and otherwise
harm our business, financial condition, results of operations and prospects. Problems in our manufacturing process could restrict our ability to meet market
demand for our products.

Further, certain of our product candidates may require components that are unavailable or difficult to acquire or manufacture at the necessary scale and in
compliance with regulatory requirements to support our clinical trials or, if approved, commercial efforts. In addition, we may have to rely on third-party
CMOs  to  manufacture  these  components  and  the  final  product  candidates.  We  may  not  have  full  control  of  these  CMOs  and  they  may  prioritize  other
customers or be unable to provide us with enough manufacturing capacity to meet our objectives. Even if we decide to manufacture the product candidates or
their  components  ourselves,  we  may  face  extremely  high  costs  and  long  timelines  to  build  and  maintain  manufacturing  facilities.  We  may  rely  on  CMOs
outside the U.S. for certain components of our product candidates, and may be subject to importation regulations that may affect our ability to manufacture or
increase the cost of our product candidates.

We also may encounter problems hiring and retaining the experienced scientific, quality-control and manufacturing personnel needed to operate or supervise
the  necessary  manufacturing  processes,  which  could  result  in  delays  in  production  or  difficulties  in  maintaining  compliance  with  applicable  regulatory
requirements.

Any  problems  in  manufacturing  processes  or  facilities  could  make  us  a  less  attractive  collaborator  for  potential  partners,  including  larger  pharmaceutical
companies and academic research institutions, which could limit our access to additional attractive development programs.

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 operations and development efforts.

We are increasingly dependent upon information technology systems, infrastructure, and data to operate our business. In the ordinary course of business, we
collect, store, and transmit large amounts of confidential information (including but not limited to intellectual property, proprietary business information, and
personal information). It is critical that we do so in a secure manner to maintain the confidentiality and integrity of such confidential information. We also
have outsourced elements of our operations to third parties, and as a result we manage a number of third-party vendors who may or could have access to our
confidential information. Our third-party collaborators also have access to large amounts of confidential information relating to our operations, including our
research and development efforts. The size and complexity of our information technology systems, and those of third-party vendors and collaborators, and the
large amounts of confidential information stored on those systems, make such systems potentially vulnerable to service interruptions or systems failures, or to
security breaches from inadvertent or intentional actions by our employees, third-party vendors, and/or business partners, or from cyber-attacks by malicious
third parties. In addition to such risks, the adoption of new technologies may also increase our exposure to cybersecurity breaches and failures. Cyber-attacks
are increasing in their frequency, sophistication, and intensity, and have become increasingly difficult to detect. Cyber-attacks could include the deployment
of  harmful  malware,  denial-of-service  attacks,  social  engineering,  “phishing”  scams  and  other  means  to  affect  service  reliability  and  threaten  the
confidentiality, integrity, and availability of information. Significant disruptions of these information technology systems or security breaches could adversely
affect our business operations and/or result in the loss, misappropriation, and/or unauthorized access, use, or disclosure of, or the prevention of access to,
confidential information (including but not limited to trade secrets or other intellectual property, proprietary business information, and personal information),
and could result in financial, legal, business, and reputational harm to us and would adversely affect our operations, including our discovery and research and
development  programs.  For  example,  any  such  event  that  leads  to  unauthorized  access,  use,  or  disclosure  of  personal  information,  including  personal
information  regarding  our  employees  of  future  clinical  trial  participants,  could  harm  our  reputation,  require  us  to  comply  with  federal  and/or  state  breach
notification laws and foreign law equivalents, and otherwise subject us to liability, including financial penalties and fines, under laws and regulations that
protect

55

 
the  privacy  and  security  of  personal  information.  Also,  the  loss  of  preclinical  or  clinical  trial  data  from  completed  or  future  preclinical  or  clinical  trials,
respectively, 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. Security breaches and other inappropriate access can be difficult to detect, and any delay in identifying them may lead to increased harm of
the  type  described  above.  While  we  have  implemented  security  measures  to  protect  our  information  technology  systems  and  infrastructure,  there  is  no
assurance that such measures will prevent service interruptions or security breaches that could adversely affect our business.

Interruptions  in  the  availability  of  server  systems  or  communications  with  internet  or  cloud-based  services,  or  failure  to  maintain  the  security,
confidentiality, accessibility or integrity of data stored on such systems, could harm our business.

We  rely  upon  a  variety  of  internet  service  providers,  third-party  web  hosting  facilities  and  cloud  computing  platform  providers  to  support  our  business.
Failure to maintain the security, confidentiality, accessibility or integrity of data stored on such systems could result in interruptions in our operations, damage
our reputation in the market, increase our service costs, cause us to incur substantial costs, subject us to liability for damages and/or fines, and divert our
resources from other tasks, any one of which could materially adversely affect our business, financial condition, results of operations and prospects. If our
security measures or those of our third-party data center hosting facilities, cloud computing platform providers, or third-party service partners, are breached,
and unauthorized access is obtained to our data or our information technology systems, we may incur significant legal and financial exposure and liabilities.

We also do not have control over the operations of the facilities of our cloud service providers and our third party web hosting providers, and they also may be
vulnerable to damage or interruption from natural disasters, cybersecurity attacks, terrorist attacks, power outages and similar events or acts of misconduct. In
addition, any changes in these providers’ service levels may adversely affect our ability to meet our requirements and operate our business

Legal, political and economic uncertainty surrounding the planned exit of the United Kingdom from the European Union is a source of instability and
uncertainty.

In June 2016, a majority of the eligible members of the electorate in the United Kingdom voted to withdraw from the EU in a national referendum, commonly
referred to as “Brexit.” Subsequently, the United Kingdom and the EU agreed to a withdrawal agreement (the “Withdrawal Agreement”). The Withdrawal
Agreement  was  approved  by  the  United  Kingdom  Parliament  and  the  United  Kingdom  formally  left  the  EU  on  January  31,  2020.  Under  the  Withdrawal
Agreement, the United Kingdom is subject to a transition period until December 31, 2020 (the “Transition Period”), during which EU rules will continue to
apply. Negotiations between the United Kingdom and the EU are expected to continue in relation to the customs and trading relationship between the United
Kingdom and the EU following the expiry of the Transition Period.

The  uncertainty  concerning  the  United  Kingdom’s  legal,  political  and  economic  relationship  with  the  EU  after  the  Transition  Period  may  be  a  source  of
instability in the international markets, create significant currency fluctuations, and/or otherwise adversely affect trading agreements or similar cross-border
co-operation arrangements (whether economic, tax, fiscal, legal, regulatory or otherwise).

56

 
 
 
 
Since the regulatory framework for pharmaceutical products in the United Kingdom covering quality, safety and efficacy of pharmaceutical products, clinical
trials,  marketing  authorization,  commercial  sales  and  distribution  of  pharmaceutical  products  is  derived  from  EU  directives  and  regulations,  Brexit  could
materially impact the future regulatory regime that applies to drugs and the approval of drug candidates in the United Kingdom. It remains to be seen how, if
at all, Brexit will impact regulatory requirements for product candidates and products in the United Kingdom. Given the lack of comparable precedent, it is
unclear what financial, trade and legal implications the withdrawal of the United Kingdom from the EU, especially in the case of the United Kingdom leaving
the EU without an agreement defining their respective trading rights and obligations, would have and how such withdrawal would affect us. The long-term
impact  of  Brexit,  including  on  our  business  and  our  industry,  will  depend  on  the  terms  that  are  negotiated  in  relation  to  the  United  Kingdom’s  future
relationship with  the  EU,  and  we  are  closely  monitoring  the  Brexit  developments  in  order  to  determine,  quantify  and  proactively  address  changes  as  they
become clear.

Risks Related to Our Financial Position and need for Additional Capital

We  have  never  generated  any  revenue  from  product  sales  and  our  ability  to  generate  revenue  from  product  sales  and  become  profitable  depends
significantly on our success in a number of areas.

We have no products approved for commercial sale, have not generated any revenue from product sales, and do not anticipate generating any revenue from
product  sales  until  sometime  after  we  have  received  regulatory  approval  for  the  commercial  sale  of  a  product  candidate  that  we  discover.  Our  ability  to
generate revenue and achieve and retain profitability depends significantly on our success in many areas, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

selecting commercially viable product candidates and effective delivery methods;

completing research, preclinical and clinical development of product candidates;

obtaining regulatory approvals and marketing authorizations for product candidates for which we complete clinical trials;

developing  a  sustainable  and  scalable  manufacturing  process  for  product  candidates,  including  establishing  and  maintaining  commercially
viable  supply  relationships  with  third  parties,  such  as  CMOs,  and  potentially  establishing  our  own  manufacturing  capabilities  and
infrastructure;

launching and commercializing product candidates for which we obtain regulatory approvals and marketing authorizations, either directly or
with a collaborator or distributor;

accurately assessing the size and addressability of potential patient populations;

obtaining market acceptance of our product candidates as viable treatment options;

addressing any competing technological and market developments;

negotiating favorable terms in any collaboration, licensing or other arrangements into which we may enter or which may be necessary for us
to develop, manufacture or commercialize our product candidates;

maintaining good relationships with our collaborators and licensors;

maintaining, protecting and expanding our portfolio of intellectual property rights, including patents, trade secrets and know-how;

avoiding infringement of or obtaining licenses to any valid intellectual property owned or controlled by third parties; and

attracting, hiring and retaining qualified personnel.

57

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Even if one or more product candidates that we discover and develop are approved for commercial sale, we anticipate incurring significant costs associated
with  commercializing  any  approved  product  candidate  and  the  timing  of  such  costs  may  be  out  of  our  control.  Our  expenses  could  increase  beyond
expectations if we are required by the FDA or other regulatory agencies, domestic or foreign, to change our manufacturing processes or assays, or to perform
clinical, nonclinical or other types of additional studies. If we are successful in obtaining regulatory approvals to market one or more product candidates, our
revenue will be dependent, in part, upon the size of the markets in the territories for which we gain regulatory approval, the accepted price for the product, the
ability to get reimbursement at any price and whether we own the commercial rights for that territory. If the number of our addressable disease patients is not
as significant as we estimate, the indication approved by regulatory authorities is narrower than we expect or the reasonably accepted population for treatment
is narrowed by competition, physician choice or treatment guidelines, we may not generate significant revenue from sales of such products, even if approved.
If we are not able to generate revenue from the sale of any approved products, we may never become profitable.

Our limited operating history may make difficult the evaluation of our business’s success to date and assessment of our future viability.

We are a preclinical-stage company. We were founded and commenced operations in mid-2014. Our operations to date have been limited to organizing and
staffing  our  company,  business  and  scientific  planning,  raising  capital,  acquiring  and  developing  technology,  identifying  potential  product  candidates,
undertaking  research  and  early  preclinical  studies  of  potential  product  candidates  for  ourselves  and  collaborators,  developing  the  necessary  manufacturing
capabilities and evaluating a clinical path for our pipeline programs. All of our product candidates are still in the preclinical development stage. We have not
yet demonstrated our ability to successfully initiate any clinical trials, including large-scale, pivotal clinical trials, obtain marketing approvals, manufacture
clinical  and  commercial  scale  therapeutics,  or  arrange  for  a  third-party  to  do  so  on  our  behalf,  or  conduct  sales  and  marketing  activities  necessary  for
successful commercialization.  Our  ability  to  generate  product  revenue  or  profits,  which  we  do  not  expect  will  occur  for  many  years,  if  ever,  will  depend
heavily on the successful development and eventual commercialization of our product candidates, which may never occur. We may never be able to develop
or commercialize a marketable product.

Each of our programs may require additional discovery research and then preclinical and clinical development, regulatory approval in multiple jurisdictions,
obtaining  manufacturing  supply,  capacity  and  expertise,  building  of  a  commercial  organization,  substantial  investment  and  significant  marketing  efforts
before we generate any revenue from product sales. In addition, our product candidates must be approved for marketing by the FDA or certain other foreign
regulatory agencies, including the EMA, before we may commercialize any product.

Our limited operating history, particularly in light of the rapidly evolving genome editing field, may make it difficult to evaluate our current business and
predict  our  future  performance.  Our  relatively  short  history  as  an  operating  company  makes  any  assessment  of  our  future  success  or  viability  subject  to
significant uncertainty. We will encounter risks and difficulties frequently experienced by very early stage companies in rapidly evolving fields. If we do not
address these risks successfully, our business will suffer.

We have incurred net losses in each period since our inception, anticipate that we will continue to incur net losses in the future and may never achieve
profitability.

We are not profitable and have incurred losses in each period since our inception. Our net loss was $99.5 million for the year ended December 31, 2019. As
December 31, 2019, we had an accumulated deficit of $300.9 million. We expect these losses to increase as we continue to incur significant research and
development  and  other  expenses  related  to  our  ongoing  operations,  seek  regulatory  approvals  for  our  future  product  candidates,  scale-up  manufacturing
capabilities,  maintain,  expand  and  protect  our  intellectual  property  portfolio  and  hire  additional  personnel  to  support  the  development  of  our  product
candidates and to enhance our operational, financial and information management systems.

58

 
A critical aspect of our strategy is to invest significantly in our technology to improve the efficacy and safety of potential product candidates that we discover.
Even if we succeed in discovering, developing and ultimately commercializing one or more of these product candidates, we will continue to incur losses for
the foreseeable future relating to our substantial research and development expenditures to develop our technologies. We may encounter unforeseen expenses,
difficulties, complications, delays and other unknown factors that may adversely affect our business. The size of our future net losses will depend, in part, on
the rate of future growth of our expenses and our ability to generate revenue. Our prior losses and expected future losses have had and will continue to have
an adverse effect on our stockholders’ equity and working capital. Further, the net losses we incur may fluctuate significantly from quarter to quarter and year
to year, such that a period-to-period comparison of our results of operations may not be a good indication of our future performance.

We may need to raise substantial additional funding to fund our operations. If we fail to obtain additional financing, we may be unable to complete the
development and commercialization of any product candidates.

Our  operations  have  required  substantial  amounts  of  cash  since  inception,  and  we  expect  to  spend  substantial  amounts  of  our  financial  resources  on  our
discovery  programs  going  forward  and  future  development  efforts.  Before  obtaining  marketing  approval  from  regulatory  authorities  for  the  sale  of  any
product candidate, we must complete preclinical development, manufacture (or have manufactured) product candidates and components, and then conduct
extensive clinical trials to demonstrate the safety and efficacy of any of our future product candidates in humans. Because preclinical and clinical testing is
expensive and can take many years to complete, we may require additional funding to complete these undertakings. Further, if we are able to identify product
candidates that are eventually approved, we will require significant additional amounts in order to launch and commercialize our product candidates. For the
foreseeable future, we expect to continue to rely on additional financing to achieve our business objectives.

We will require additional capital for the further development and commercialization of any product candidates and may need to raise additional funds sooner
if we choose to expand more rapidly than we presently anticipate or due to other unanticipated factors.

We cannot be certain that additional funding will be available on acceptable terms, or at all. We have no committed source of additional capital and if we are
unable  to  raise  additional  capital  in  sufficient  amounts  or  on  terms  acceptable  to  us,  we  may  have  to  significantly  delay,  scale  back  or  discontinue  the
development,  manufacture  or  commercialization  of  our  product  candidates  or  other  research  and  development  initiatives.  Our  collaboration  and  license
agreements  may  also  be  terminated  if  we  are  unable  to  meet  the  payment  or  other  obligations  under  the  agreements.  We  could  be  required  to  seek
collaborators for product candidates at an earlier stage than otherwise would be desirable or on terms that are less favorable than might otherwise be available
or  relinquish  or  license  on  unfavorable  terms  our  rights  to  product  candidates  in  markets  where  we  otherwise  would  seek  to  pursue  development  or
commercialization ourselves.

Any of the above events could significantly harm our business, prospects, financial condition and results of operations and cause the price of our common
stock to decline.

Raising additional capital may cause dilution to our stockholders and restrict our operations.

We will need additional capital in the future to continue our planned operations. To the extent that we raise additional capital through the sale of equity or
convertible debt securities, the ownership interest of our existing stockholders may be diluted, and the terms of these securities may include liquidation or
other  preferences  that  adversely  affect  the  rights  of  our  common  stockholders.  Debt  financing  and  preferred  equity  financing,  if  available,  may  involve
agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or
declaring dividends.

59

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

Our  results  of  operations  could  be  adversely  affected  by  general  conditions  in  the  national  or  global  economy  and  financial  markets.  For  example,
governmental statements, actions or policies, political unrest and global financial crises can cause extreme volatility and disruptions in the capital and credit
markets.  A  severe  or  prolonged  economic  downturn,  political  unrest  or  additional  global  financial  crises  could  result  in  a  variety  of  risks  to  our  business,
including weakened demand for our products, if approved, or our ability to raise additional capital when needed on acceptable terms, if at all. A weak or
declining  economy  could  also  strain  our  suppliers,  possibly  resulting  in  supply  disruption.  Any  of  the  foregoing  could  harm  our  business  and  we  cannot
anticipate all of the ways in which the current economic climate, further political developments and financial market conditions could adversely impact our
business.

Inadequate funding for the FDA and other government agencies could hinder their ability to hire and retain key leadership and other personnel, prevent
new  products  and  services  from  being  developed  or  commercialized  in  a  timely  manner  or  otherwise  prevent  those  agencies  from  performing  normal
business functions on which the operation of our business may rely, which could negatively impact our business.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, ability to
hire and retain key personnel and accept the payment of user fees, and statutory, regulatory, and policy changes. Average review times at the agency have
fluctuated in recent years as a result. In addition, government funding of other government agencies on which our operations may rely, including those that
fund research and development activities, is subject to the political process, which is inherently fluid and unpredictable.

Disruptions  at  the  FDA  and  other  agencies  may  also  slow  the  time  necessary  for  new  drugs  to  be  reviewed  and/or  approved  by  necessary  government
agencies,  which  would  adversely  affect  our  business.  For  example,  over  the  last  several  years,  including  beginning  on  December  22,  2018,  the  U.S.
government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other
government employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely
review and process our regulatory submissions, which could have a material adverse effect on our business.

Risks Related to Our Reliance on Third Parties

Our technological advancements and any potential for revenue may be derived in part from our collaborations with Novartis and Regeneron, and if either
of these collaboration agreements were to be terminated or materially altered, our business, financial condition, results of operations and prospects would
be harmed.

In December 2014, we entered into a collaboration agreement with Novartis Institutes for BioMedical Research, Inc. (“Novartis”), as amended (the “2014
Novartis  Agreement”)  regarding  the  discovery  of  new  CRISPR/Cas9-based  therapies  principally  using  chimeric  antigen  receptor  T  (“CAR-T”)  cells  and
hematopoietic stem cells (“HSCs”). Under the Novartis collaboration agreement, we received a commitment to advance multiple programs. Pursuant to the
2014 Novartis Agreement, we granted Novartis exclusive rights to further develop and commercialize products arising out of the CAR-T cell program during
the research term. Regarding HSCs, we are jointly advancing multiple programs with Novartis and have agreed to a process for assigning development and
ownership  rights,  which  may  enable  us  to  develop  our  own  proprietary  HSC  pipeline.  In  December  2018,  we  expanded  our  collaboration  agreement  with
Novartis  to  include  discovery  of  CRISPR/Cas9-based  therapies  using  certain  limbal  stem  cells  primarily  against  selected  gene  targets  by  Novartis.  The
research portion of our agreement with Novartis ended in December 2019, and we cannot guarantee that Novartis will continue to pursue programs that it has
selected through our collaboration.

60

 
 
In April 2016, we entered into a collaboration agreement with Regeneron Pharmaceuticals, Inc. (“Regeneron”) that includes a product component to research,
develop and commercialize CRISPR/Cas-based therapeutic products primarily focused on genome editing in the liver as well as a technology collaboration
component, pursuant to which we and Regeneron will engage in research and development activities aimed at discovering and developing novel technologies
and  improvements  to  CRISPR/Cas9  technology  to  enhance  our  genome  editing  platform.  Pursuant  to  the  Regeneron  collaboration  agreement,  we  granted
Regeneron exclusive rights to select up to 10 targets, subject to certain restrictions. We retained the rights to solely develop certain indications, other than
ATTR, which is subject to a Co/Co agreement with Regeneron. We also have the right to choose additional liver targets for our own development during the
collaboration term, which  may  be  subject  to  additional  Co/Co  options  by  Regeneron.  In  July  2018,  we  entered  into  the  first  Co/Co  agreement  directed  to
ATTR (the “ATTR Co/Co”), under which we will be the clinical and commercial lead for ATTR activities. On December 13, 2019, Regeneron informed us
that  it  would  exercise  its  right  under  the  ATTR  Co/Co  agreement  to  modify  its  shares  of  worldwide  developments  costs  and  profits  from  50%  to  25%,
effective  six  months  after  its  notice.  Pursuant  to  the ATTR Co/Co agreement, Regeneron  funded  approximately  50%  of  the  program’s  development  costs
through 2019. Starting June 2020 and thereafter, Regeneron will share approximately 25% of worldwide development costs and commercial profits for the
ATTR program. We continue to lead the development and commercialization of any resulting ATTR products.

Either Novartis or Regeneron may change its strategic focus or pursue alternative technologies in a manner that results in reduced, delayed or no revenue to
us. Each of Novartis and Regeneron has a variety of marketed products and product candidates either by itself or under collaboration with other companies,
including some of our competitors, and the respective corporate objectives of Novartis or Regeneron may not be consistent with our best interests. Regeneron
may  change  its  position  regarding  its  participation  and  funding  of  our  joint  ATTR  activities,  which  may  impact  our  ability  to  successfully  pursue  that
program. If either of our collaboration partners fails to develop, obtain regulatory approval for or ultimately commercialize any product candidate from the
development programs governed by the respective collaboration agreement in the applicable territories, or if either of our collaboration partners breaches or
terminates our collaboration with it, our business, financial condition, results of operations and prospects could be harmed. In addition, any material alteration
of the collaboration agreements, or dispute or litigation proceedings we may have with either Novartis or Regeneron in the future could delay development
programs,  create  uncertainty  as  to  ownership  of  or  access  to  intellectual  property  rights,  distract  management  from  other  business  activities  and  generate
substantial expense.

Our  existing  and  future  collaborations  will  be  important  to  our  business.  If  we  are  unable  to  maintain  any  of  these  collaborations,  or  if  these
collaborations are not successful, our business could be adversely affected.

We have limited capabilities for product discovery and development and do not yet have any capability for sales, marketing or distribution. Accordingly, we
have  entered,  and  plan  to  enter,  into  collaborations  with  other  companies,  including  our  therapeutic-focused  collaboration  agreements  with  Novartis  and
Regeneron, that we believe can provide such capabilities. These therapeutic-focused collaborations provide us with important technologies and/or funding for
our programs and technology, and we expect to receive additional technologies and funding under these and other collaborations in the future. Our existing
therapeutic collaborations, and any future collaborations we enter into, may pose a number of risks, including the following:

•

•

•

•

•

collaborators have significant discretion in determining the efforts and resources that they will apply;

collaborators may not perform their obligations as expected;

collaborators may dispute the amounts of payments owed;

collaborators may not pursue development and commercialization of any product candidates that achieve regulatory approval or may elect
not to continue or renew development or commercialization programs or license arrangements based on clinical trial results, changes in the
collaborators’  strategic  focus  or  available  funding,  or  external  factors,  such  as  a  strategic  transaction  that  may  divert  resources  or  create
competing priorities;

collaborators  may  delay  clinical  trials,  provide  insufficient  funding  for  a  clinical  trial  program,  stop  a  clinical  trial  or  abandon  a  product
candidate, repeat or conduct new clinical trials or require a new formulation of a product candidate for clinical testing;

61

 
 
 
 
 
 
•

•

•

•

•

•

•

•

•

collaborators could develop independently, or with third parties, products that compete directly or indirectly with our products and product
candidates if the collaborators believe that the competitive products are more likely to be successfully developed or can be commercialized
under terms that are more economically attractive than ours;

product candidates discovered in collaboration with us may be viewed by our collaborators as competitive with their own product candidates
or products, which may cause collaborators to cease to devote resources to the development or commercialization of our product candidates;

collaborators may dispute ownership or rights in jointly developed technologies or intellectual property;

collaborators may fail to comply with applicable legal and regulatory requirements regarding the development, manufacture, sale, distribution
or marketing of a product candidate or product;

collaborators with sales, marketing, manufacturing and distribution rights to one or more of our product candidates that achieve regulatory
approval may not commit sufficient resources to the sale, marketing, manufacturing and distribution of such product or products;

disagreements  with  collaborators,  including  disagreements  over  proprietary  rights,  contract  interpretation,  payment  obligations  or  the
preferred  course  of  discovery,  development,  sales  or  marketing,  might  cause  delays  or  terminations  of  the  research,  development  or
commercialization of product candidates, might lead to additional and burdensome responsibilities for us with respect to product candidates,
or might result in litigation or arbitration, any of which would be time-consuming and expensive;

collaborators may not properly maintain or defend their or our relevant intellectual property rights or may use our proprietary information in
such  a  way  as  to  invite  litigation  that  could  jeopardize  or  invalidate  our  intellectual  property  or  proprietary  information  or  expose  us  to
potential litigation and liability;

collaborators may infringe the intellectual property rights of third parties, which may expose us to litigation and potential liability;

if a collaborator of ours is involved in a business combination or cessation, the collaborator might deemphasize or terminate the development
or commercialization of any product candidate licensed to it by us; and

collaborations may be terminated by the collaborator, and, if terminated, we could be required to raise additional capital to pursue further
development or commercialization of the applicable product candidates, or potentially lose access to the collaborator’s intellectual property.

If  our  therapeutic  collaborations  do  not  result  in  the  successful  discovery,  development  and  commercialization  of  products  or  if  one  of  our  collaborators
terminates  its  agreement  with  us,  we  may  not  receive  any  future  research  funding  or  milestone  or  royalty  payments  under  the  collaboration.  If  we  do  not
receive the funding we expect under these agreements, our development and commercialization of our technology and product candidates could be delayed
and  we  may  need  additional  resources  to  develop  product  candidates  and  our  technology.  All  of  the  risks  relating  to  product  discovery,  development,
regulatory approval and commercialization described in this report also apply to the activities of our therapeutic collaborators.

Additionally, if one of our collaborators terminates its agreement with us, we may find it more difficult to attract new collaborators and our perception in the
business and financial communities could be adversely affected.

For some of our programs, we may in the future determine to collaborate with pharmaceutical and biotechnology companies for discovery, development and
potential commercialization of therapeutic products. We face significant competition in seeking appropriate collaborators because, for example, third-parties
have comparable rights to the CRISPR/Cas9 system or similar genome editing technologies. Our ability to reach a definitive agreement for a collaboration
will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration
and  the  proposed  collaborator’s  evaluation  of  a  number  of  factors.  If  we  are  unable  to  reach  agreements  with  suitable  collaborators  on  a  timely  basis,  on
acceptable terms, or at

62

 
 
 
 
 
 
 
 
 
 
 
all, we may have to curtail discovery efforts or the development of a product candidate, reduce or delay its development program or one or more of our other
development  programs,  delay  its  potential  manufacture  or  commercialization,  or  reduce  the  scope  of  any  sales  or  marketing  activities,  or  increase  our
expenditures  and  undertake  development  or  commercialization  activities  at  our  own  expense.  If  we  elect  to  fund  and  undertake  discovery,  development,
manufacturing or commercialization activities on our own, we may need to obtain additional expertise and additional capital, which may not be available to
us  on  acceptable  terms  or  at  all.  If  we  fail  to  enter  into  collaborations  and  do  not  have  sufficient  funds  or  expertise  to  undertake  the  necessary  discovery,
development,  manufacturing  and  commercialization  activities,  we  may  not  be  able  to  further  develop  our  product  candidates,  manufacture  the  product
candidates, bring them to market or continue to develop our technology and our business may be materially and adversely affected.

We expect to rely in part on third parties to manufacture our clinical product supplies, and we intend to rely on third parties for at least a portion of the
manufacturing  process  of  our  product  candidates,  if  approved.  Our  business  could  be  harmed  if  the  third  parties  fail  to  provide  us  with  sufficient
quantities of product inputs or fail to do so at acceptable quality levels or prices or fail to meet legal and regulatory requirements.

We do not currently own any facility that may be used as our clinical-scale manufacturing and processing facility and must rely on outside vendors, such as
CMOs, to manufacture supplies and process our product candidates. We have only recently begun to manufacture and process product candidate components
on  a  clinical  scale  and  may  not  be  able  to  successfully  complete  or  continue  to  do  so  for  our  product  candidates.  We  will  make  changes  as  we  work  to
optimize  the  manufacturing  process,  and  we  cannot  be  sure  that  even  minor  changes  in  the  process  will  result  in  therapies  that  are  safe,  potent,  pure  or
effective.

The  facilities  used  by  our  contract  manufacturers  to  manufacture  our  product  candidates  must  be  inspected  and  approved  by  the  FDA  or  other  foreign
regulatory agencies pursuant to inspections that will be conducted after we submit an application to the FDA or other foreign regulatory agencies. We will be
dependent  on  our  contract  manufacturing  partners  to  manufacture  adequate  supply  of  our  product  candidates  and  components  in  a  timely  manner  and  in
accordance with our specification. We also will depend on these entities for compliance with legal and regulatory requirements for manufacture, including
current good manufacturing practice (“cGMP”), and in certain cases, current good tissue practice (“cGTP”), requirements of our product candidates. If our
contract  manufacturers  cannot  successfully  manufacture  material  that  conforms  to  our  specifications  and  the  strict  regulatory  requirements  of  the  FDA  or
other regulatory authorities, they will not be able to secure and/or maintain regulatory approval for their manufacturing facilities. In addition, we have no
control  over  the  ability  of  our  contract  manufacturers  to  maintain  adequate  quality  control,  quality  assurance  and  qualified  personnel,  particularly  as  we
increase the scale of our manufactured material. If the FDA or a comparable foreign regulatory authority does not approve these facilities for the manufacture
of  our  product  candidates  or  if  it  withdraws  any  such  approval  in  the  future,  we  may  need  to  find  alternative  manufacturing  facilities,  which  would
significantly impact our ability to develop, obtain regulatory approval for or market our product candidates, if approved.

We will rely on third parties to conduct our clinical trials. If these third parties do not successfully carry out their contractual duties or meet expected
deadlines or comply with legal and regulatory requirements, we may not be able to obtain regulatory approval of or commercialize any potential product
candidates.

We will depend upon third parties, including independent investigators, to conduct our clinical trials under agreements with universities, medical institutions,
CROs,  strategic  partners  and  others.  We  expect  to  have  to  negotiate  budgets  and  contracts  with  CROs  and  trial  sites,  which  may  result  in  delays  to  our
development timelines and increased costs.

We will rely heavily on third parties over the course of our clinical trials, and, as a result, will have limited control over the clinical investigators and limited
visibility  into  their  day-to-day  activities,  including  with  respect  to  their  compliance  with  the  approved  clinical  protocol  and  other  legal,  regulatory  and
scientific standards. Nevertheless, we are responsible for ensuring that each of our studies is conducted in accordance with the applicable protocol and legal,
regulatory and scientific standards, and our reliance on third parties does not relieve us of our legal responsibilities. We and these third parties are required to
comply  with  good  clinical  practice  (“GCP”)  requirements,  which  are  regulations  and  guidelines  enforced  by  the  FDA  and  comparable  foreign  regulatory
authorities  for  product  candidates  in  clinical  development.  Regulatory  authorities  enforce  these  GCP  requirements  through  periodic  inspections  of  trial
sponsors, clinical investigators and trial sites. If we or any of these third parties fail to comply

63

 
with applicable GCP requirements, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or comparable foreign regulatory
authorities  may  require  us  to  suspend  or  terminate  these  trials  or  perform  additional  preclinical  studies  or  clinical  trials  before  approving  our  marketing
applications.  We  cannot  be  certain  that,  upon  inspection,  such  regulatory  authorities  will  determine  that  any  of  our  clinical  trials  comply  with  the  GCP
requirements. In addition, our clinical trials must be conducted with product produced under cGMP, and in certain cases, cGTP, requirements and may require
a large number of test patients.

Our failure or any failure by these third parties to comply with these requirements or to recruit a sufficient number of patients may require us to repeat clinical
trials, which would delay the regulatory approval process. Moreover, our business may be implicated if any of these third parties violates applicable federal,
state or local, as well as foreign, laws and regulations, such as the fraud and abuse or false claims laws and regulations or privacy and security laws.

Any third parties conducting our future clinical trials will not be our employees and, except for remedies that may be available to us under our agreements
with such third parties, we cannot control whether they devote sufficient time and resources to our ongoing preclinical, clinical, and nonclinical programs.
These third parties may also have relationships with other commercial entities, including our competitors, for whom they may also be conducting clinical
trials or other product development activities, which could affect their performance on our behalf. If these third parties do not successfully carry out their
contractual  duties  or  obligations  or  meet  expected  deadlines,  if  they  need  to  be  replaced  or  if  the  quality  or  accuracy  of  the  clinical  data  they  obtain  is
compromised due to the failure to adhere to our clinical protocols or regulatory requirements or for other reasons, our clinical trials may be extended, delayed
or terminated and we may not be able to complete development of, obtain regulatory approval of or successfully commercialize our product candidates. As a
result, our financial results and the commercial prospects for our product candidates would be harmed, our costs could increase and our ability to generate
revenue could be delayed.

If any of our relationships with these third-party CROs or others terminate, we may not be able to enter into arrangements with alternative CROs or other
third parties or to do so on commercially reasonable terms. Switching or adding additional CROs involves additional cost and requires management time and
focus.  In  addition,  the  transition  to  a  new  CRO  may  result  in  delays,  which  can  materially  impact  our  ability  to  meet  our  desired  clinical  development
timelines. Though we carefully manage our relationships with our CROs, there can be no assurance that we will not encounter similar challenges or delays in
the future or that these delays or challenges will not have a material adverse impact on our business, financial condition and prospects.

Risks Related to Employee Matters and Managing Growth

We expect to expand our research, development, manufacturing, clinical and regulatory capabilities, and, as a result, we may encounter difficulties in
hiring capable personnel and otherwise managing our growth, which could disrupt our operations.

We  expect  to  experience  growth  in  the  number  of  our  employees  and  the  scope  of  our  operations,  including  the  areas  of  technology  research,  product
development and manufacturing, clinical, regulatory and quality affairs and, if any product candidates are submitted for or receive marketing approval, sales,
marketing and distribution. To manage our anticipated future growth, we must continue to implement and improve our managerial, operational and financial
systems,  expand  our  facilities  and  continue  to  recruit  and  train  additional  qualified  personnel.  Due  to  our  limited  financial  resources,  the  significant
competition  for  qualified  employees  in  our  market  and  industry,  and  the  limited  experience  of  our  management  team  in  managing  a  company  with  such
anticipated growth, we may not be able to recruit and train additional qualified personnel or to otherwise effectively manage the expansion of our operations.
The expansion of our operations may lead to significant costs, and may divert our management and business development resources. Any inability to manage
growth could delay the execution of our business and development plans or disrupt our operations.

64

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

We  are  highly  dependent  on  the  research  and  development,  clinical,  legal,  financial  and  business  development  expertise  of  John  M.  Leonard,  M.D.,  our
President  and  Chief  Executive  Officer,  Glenn  Goddard,  our  Executive  Vice  President  and  Chief  Financial  Officer,  José  E.  Rivera,  our  Executive  Vice
President, General Counsel, Andrew Schiermeier, our Executive Vice President and Chief Operating Officer and Laura Sepp-Lorenzino, our Executive Vice
President and Chief Scientific Officer as well as the other principal members of our management, scientific and clinical teams. Although we have entered into
employment arrangements with our executive officers, each of them may terminate their employment with us at any time. We do not maintain “key person”
insurance for any of our executives or other employees.

Recruiting and retaining qualified scientific, clinical, manufacturing and sales and marketing personnel will also be important for our success. The loss of the
services of our executive officers or other key employees could impede the achievement of our research, development and commercialization objectives and
seriously harm our ability to successfully implement our business strategy. Furthermore, replacing executive officers and key employees may be difficult and
may  take  an  extended  period  of  time  because  of  the  limited  number  of  individuals  in  our  industry  with  the  breadth  of  skills  and  experience  required  to
successfully develop, gain regulatory approval of and commercialize products using our technology. Competition to hire from this limited pool is intense, and
we  may  be  unable  to  hire,  train,  retain  or  motivate  these  key  personnel  on  acceptable  terms  given  the  competition  among  numerous  pharmaceutical  and
biotechnology  companies,  universities  and  research  institutions  for  similar  personnel.  The  market  for  qualified  personnel  in  the  biotechnology  space
generally, and genome editing and gene therapy fields in particular, in and around the Cambridge, Massachusetts area is especially competitive. In addition,
we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development and commercialization
strategies. Our consultants and advisors may be employed by employers other than us and may have commitments under consulting or advisory contracts
with other entities that may limit their availability to us. Further, some of the qualified personnel that we hire and recruit are not U.S. citizens, and there is
uncertainty with regard to their future employment status due to the current U.S. administration’s announced intention of modifying the legal framework for
non-U.S. citizens to be employed in the U.S. If we are unable to continue to attract and retain high quality personnel, our ability to pursue our growth strategy
will be limited.

Risks Related to Government Regulation

While the regulatory framework for approval of gene therapy including genome editing products exists, the lack of specific guidance and precedent for
genome-edited products makes the regulatory approval process potentially more unpredictable and we may experience significant delays in the clinical
development and regulatory approval, if any, of our product candidates.

The  research,  testing,  manufacturing,  labeling,  approval,  selling,  import,  export,  marketing  and  distribution  of  drug  products,  including  genome  editing
therapeutics and engineered cell therapies, are subject to extensive regulation by the FDA in the U.S. and other regulatory authorities. We are not permitted to
market any drug or biological product, including in vivo products or engineered cell therapies, in the U.S. until we receive regulatory approval from the FDA.
We have not previously submitted a BLA to the FDA, or similar approval filings to comparable foreign authorities. A BLA must include extensive preclinical
and clinical data and supporting information to establish that the product candidate is safe and effective or, for biological products, safe, pure and potent for
each desired indication. The application must also include significant information regarding the chemistry, manufacturing and controls for the product, and
the manufacturing facilities must complete a successful pre-approval inspection by the FDA, or applicable foreign authority, prior to the approval or licensure
of the product. We expect the novel nature of our product candidates to create further challenges in obtaining regulatory approval. For example, the FDA has
not  approved  any  nuclease  edited  cell  therapies  for  human  therapeutic  use.  The  FDA  may  also  require  a  panel  of  experts,  referred  to  as  an  Advisory
Committee, to deliberate on the adequacy of the safety and efficacy data to support approval. The opinion of the Advisory Committee, although not binding,
may have a significant impact on our ability to obtain approval of any product candidates that we develop based on the completed clinical trials. Moreover,
while we are not aware of any specific genetic or biomarker diagnostic tests for which regulatory approval would be necessary in order to advance any of our
product candidates to clinical trials or potential commercialization, in the future regulatory agencies may require the development and approval of such tests.
Accordingly,  the  regulatory  approval  pathway  for  such  product  candidates  may  be  uncertain,  complex,  expensive  and  lengthy,  and  approval  may  not  be
obtained.

65

 
In December 2018, the World Health Organization (“WHO”) established the Expert Advisory Committee on Developing Global Standards for Governance
and  Oversight  of  Human  Genome  Editing.  While  the  standards  are  expected  to  focus  primarily  on  germline  modifications,  the  guidelines  could  impact
somatic cell editing research programs.

In August 2019, the WHO Expert Advisory Committee recommended initiating the first phase of a new global registry to track research on human genome
editing.  Accepting  this  recommendation,  the  WHO  announced  plans  for  an  initial  phase  of  the  registry  using  the  International  Clinical  Trials  Registry
Platform  (“ICTRP”).  This  phase  will  include  worldwide  registries  for  both  somatic  cell  editing  and  germline  editing  clinical  trials.  Registration  of  these
clinical trials in the WHO’s registry is voluntary.

In addition, clinical trials can be delayed or terminated for a variety of reasons, including delays or failures related to:

•

•

•

•

•

•

•

•

•

•

•

obtaining and maintaining regulatory authorization to conduct a trial, if applicable;

the availability of financial resources to begin and complete the planned trials;

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

obtaining approval at each clinical trial site by an independent IRB;

recruiting suitable patients to participate in a trial in a timely manner;

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

clinical trial sites deviating from trial protocol, not complying with GCP requirements or dropping out of a trial;

addressing any patient safety concerns that arise during the course of a trial;

addressing any conflicts with new or existing laws or regulations;

adding new clinical trial sites; or

manufacturing qualified materials under cGMP regulations for use in clinical trials.

Patient enrollment is a significant factor in the timing of clinical trials and is affected by many factors. Further, a clinical trial may be suspended or terminated
by us, the IRBs for the institutions in which such trials are being conducted, the DSMB for such trial or the FDA or other regulatory authorities due to a
number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical
trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side
effects, failure to demonstrate a benefit from using a product candidate, changes in governmental regulations or administrative actions or lack of adequate
funding to continue the clinical trial. If we experience termination of, or delays in the completion of, any clinical trial of product candidates, the commercial
prospects for our product candidates will be harmed, and our ability to generate product revenue will be impaired. In addition, any delays in completing any
clinical trials will increase our costs, slow down our product development and approval process and jeopardize our ability to commence product sales and
generate revenue.

66

 
 
 
 
 
 
 
 
 
 
 
 
Obtaining  and  maintaining  regulatory  approval  of  our  product  candidates  in  one  jurisdiction  does  not  mean  that  we  will  be  successful  in  obtaining
regulatory approval of product candidates in other jurisdictions.

Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not guarantee that we will be able to obtain or maintain
regulatory  approval  in  any  other  jurisdiction,  but  a  failure  or  delay  in  obtaining  regulatory  approval  in  one  jurisdiction  may  have  a  negative  effect  on  the
regulatory approval process in others. For example, even if the FDA grants marketing approval of a product candidate, comparable regulatory authorities in
foreign jurisdictions must also authorize the manufacturing, marketing and sale of the product candidate in those countries. Approval procedures vary among
jurisdictions  and  can  involve  requirements  and  administrative  review  periods  different  from  those  in  the  U.S.,  including  additional  preclinical  studies  or
clinical  trials  as  clinical  studies  conducted  in  one  jurisdiction  may  not  be  accepted  by  regulatory  authorities  in  other  jurisdictions.  In  many  jurisdictions
outside the U.S., a product candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that
we are allowed to charge for our products is also subject to approval.

Obtaining foreign regulatory approvals and compliance with foreign regulatory requirements could result in significant delays, difficulties and costs for us
and could delay or prevent the introduction of our products in certain countries. If we fail to comply with the regulatory requirements in international markets
or to receive applicable marketing approvals, our target market will be reduced and our ability to realize the full market potential of our product candidates
will be harmed.

Even  if  we  receive  regulatory  approval  of  any  product  candidates  or  therapies,  we  will  be  subject  to  ongoing  regulatory  obligations  and  continued
regulatory review, which may result in significant additional expense and we may be subject to penalties if we fail to comply with regulatory requirements
or experience unanticipated problems with our product candidates.

If any of our product candidates are approved, they will be subject to ongoing regulatory requirements for manufacturing, labeling, packaging, distribution,
storage,  advertising,  promotion,  sampling,  record-keeping,  conduct  of  post-marketing  studies  and  submission  of  safety  and  efficacy  data,  and  other  post-
market information, including both federal and state requirements in the U.S. and requirements of comparable foreign regulatory authorities. In addition, we
will be subject to continued compliance with cGMP and GCP, and in certain cases, cGTP, requirements for any clinical trials that we conduct post-approval.

Manufacturers and manufacturers’ facilities are required to comply with extensive FDA and comparable foreign regulatory authority requirements, including
ensuring  that  quality  control  and  manufacturing  procedures  conform  to  cGMP  and,  in  certain  cases,  cGTP  requirements.  As  such,  we  and  our  contract
manufacturers will be subject to continual review and inspections to assess compliance with cGMP and adherence to commitments made in any BLA, other
marketing applications, and previous responses to inspection observations. Accordingly, we and others with whom we work must continue to expend time,
money, and effort in all areas of regulatory compliance, including manufacturing, production and quality control.

Any regulatory approvals that we receive for our product candidates may be subject to limitations on the approved indicated uses for which the product may
be  marketed  or  to  the  conditions  of  approval,  or  contain  requirements  for  potentially  costly  post-marketing  testing,  including  Phase  IV  clinical  trials  and
surveillance  to  monitor  the  safety  and  efficacy  of  the  product  candidate.  The  FDA  may  also  require  a  REMS  program  as  a  condition  of  approval  of  our
product  candidates,  which  could  entail  requirements  for  long-term  patient  follow-up,  a  medication  guide,  physician  communication  plans  or  additional
elements  to  ensure  safe  use,  such  as  restricted  distribution  methods,  patient  registries  and  other  risk  minimization  tools.  In  addition,  if  the  FDA  or  a
comparable  foreign  regulatory  authority  approves  our  product  candidates,  we  will  have  to  comply  with  legal  or  regulatory  requirements  including
submissions of safety and other post-marketing information and reports and registration.

67

 
The  FDA  may  seek  to  impose  consent  decrees  or  withdraw  approval  if  compliance  with  regulatory  requirements  and  standards  is  not  maintained  or  if
problems occur after the product reaches the market. Later discovery of previously unknown problems with our product candidates, including adverse events
of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements,
may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical studies to assess new safety risks;
or imposition of distribution restrictions or other restrictions under a REMS program. Other potential consequences include, among other things:

•

•

•

•

•

restrictions on the marketing or manufacturing of our products, withdrawal of the product from the market or voluntary or mandatory product
recalls;

fines, warning letters or holds on clinical trials;

refusal  by  the  FDA  to  approve  pending  applications  or  supplements  to  approved  applications  filed  by  us  or  suspension  or  revocation  of
license approvals;

product seizure or detention or refusal to permit the import or export of our product candidates; and

injunctions or the imposition of civil or criminal penalties.

The FDA strictly regulates marketing, labeling, advertising, and promotion of products that are placed on the U.S. market. Products may be promoted only for
the approved indications and in accordance with the provisions of the approved label. The FDA and other agencies actively enforce the laws and regulations
prohibiting the promotion of off-label uses and a company that is found to have improperly promoted off-label uses may be subject to significant liability.

The policies of the FDA and of other regulatory authorities may change and additional government regulations may be enacted that could prevent, limit or
delay regulatory approval of our product candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future
legislation or administrative or executive action, either in the U.S. or abroad. For example, certain policies of the current or future U.S. administration may
impact our business and industry. Namely, the current administration has taken, or may take, several executive actions, including the issuance of a number of
executive  orders,  that  could  impose  significant  burdens  on,  or  otherwise  materially  delay,  the  FDA’s  ability  to  engage  in  routine  regulatory  and  oversight
activities such as implementing statutes through rulemaking and issuance of guidance. It is difficult to predict how any of these rules or requirements will be
implemented, and the extent to which they will impact the FDA’s ability to exercise its regulatory authority. If these executive actions impose constraints on
the  FDA’s  ability  to  engage  in  oversight  and  implementation  activities  in  the  normal  course,  our  business  may  be  negatively  impacted.  If  we  are  slow  or
unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory and legal
compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability.

Healthcare cost control initiatives, including healthcare legislative and regulatory reform measures, may have a material adverse effect on our business
and results of operations.

The U.S. and many foreign jurisdictions have enacted or proposed legislative and regulatory changes affecting the healthcare system that could prevent or
delay  marketing  approval  of  our  product  candidates  or  any  future  product  candidates,  restrict  or  regulate  post-approval  activities  and  affect  our  ability  to
profitably sell any product candidates for which we obtain marketing approval. Changes in regulations, statutes or the interpretation of existing regulations
could impact our business in the future by requiring, for example: (i) changes to our manufacturing arrangements; (ii) additions or modifications to product
labeling; (iii) additional regulation or restrictions on pricing and reimbursement; (iv) changes to private or governmental insurance practices; (v) the recall or
discontinuation  of  our  products;  or  (vi)  additional  record-keeping  requirements.  If  any  such  changes  were  to  be  imposed,  they  could  adversely  affect  the
operation of our business.

Third-party payors, whether domestic or foreign, or governmental or commercial, are developing increasingly sophisticated methods of controlling healthcare
costs. In both the U.S. and certain foreign jurisdictions, there have been, and are expected to continue to be, a number of legislative and regulatory changes to
the health care system that could impact our ability to sell our products profitably. In the U.S., however, significant uncertainty exists regarding the provision
and financing of health care because the current administration and federal legislators have publicly declared their intention to significantly modify the current
legal and regulatory framework for the health care system but details have not been agreed upon or disclosed.

Current  legislation  at  the  U.S.  federal  and  state  levels  seeks  to  reduce  healthcare  costs  and  improve  the  quality  of  healthcare.  In  March  2010,  the  Patient
Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010 (collectively, the “Affordable Care Act”, or
“ACA”), was enacted, which substantially changed the way health care is financed by both governmental and private insurers, and significantly impacted the
U.S. pharmaceutical and biotechnology industry. The Affordable Care Act, among other things, subjects biologic products to potential competition by lower-
cost biosimilars, addresses a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs
that  are  inhaled,  infused,  instilled,  implanted  or  injected,  increases  the  minimum  Medicaid  rebates  owed  by  most  manufacturers  under  the  Medicaid  Drug
Rebate Program, extends the Medicaid Drug Rebate program to utilization of prescriptions of individuals enrolled in Medicaid managed care organizations,
subjects manufacturers to new annual fees and taxes for certain branded prescription drugs and biologic agents, creates a new Medicare Part D coverage gap
discount program, in which manufacturers must agree to offer 50% (increased to 70% pursuant to the Bipartisan Budget Act of 2018, effective as of January
1, 2019) 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,  and  provides  incentives  to  programs  that  increase  the  federal  government’s
comparative effectiveness research. At this time, the full effect that the Affordable Care Act would have on our business remains unclear.

Some of the provisions of the Affordable Care Act have yet to be implemented, and there have been judicial and Congressional challenges to certain aspects
of  the  Affordable  Care  Act,  as  well  as  recent  efforts  by  the  current  administration  to  repeal  or  replace  certain  aspects  of  the  Affordable  Care  Act.  Since
January  2017,  the  U.S.  president  has  signed  two  executive  orders  and  other  directives  designed  to  delay  the  implementation  of  certain  provisions  of  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 comprehensive repeal legislation, it has enacted laws that modify certain provisions of the Affordable Care Act. Further, significant
uncertainty exists regarding the future scope and effect of the Affordable Care Act because the current administration and federal legislators have publicly
declared their intention to significantly modify or repeal the legislation, and there are conflicting judicial decisions regarding the constitutionality of the law
which  at  least  one  federal  court  has  ruled  is  unconstitutional.  We  cannot  predict  the  ultimate  form  or  timing  of  any  modification  to,  or  repeal  of,  the
Affordable  Care  Act  or  the  effect  that  such  modification  or  repeal  would  have  on  our  business.  Public  announcements  by  the  U.S.  administration  and
members of the U.S. Congress have emphasized the administration’s significant interest in pursuing healthcare reform. Such reform efforts and any resulting
changes to the Affordable Care Act, or related regulations and laws, could impact our ability to sell our products profitably.

Other legislative changes relevant to the health care system have been adopted in the U.S. 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, will remain in effect through 2029 unless additional
Congressional action is taken. In January 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced
Medicare  payments  to  several  providers,  including  hospitals,  imaging  centers,  cancer  centers  and  other  treatment  centers,  and  increased  the  statute  of
limitations period for the government to recover overpayments to providers from three to five years. In December 2017, the U.S. president signed into law the
Tax Cuts and Jobs Act (“TCJA”) which, among other things, repealed 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  (the  “individual  mandate”),  effective  January  1,  2019.  On
December 14, 2018, a U.S. District Court

69

 
Judge  in  the  Northern  District  of  Texas,  or  the  Texas  District  Court  Judge,  ruled  that  the  individual  mandate  is  a  critical  and  inseverable  feature  of  the
Affordable Care Act, and therefore, because it was repealed as part of the TCJA, the remaining provisions of the Affordable Care Act are invalid as well. The
current Administration and CMS have both stated that the ruling will have no immediate effect, and on December 18, 2019, the Fifth Circuit U.S. Court of
Appeals  held  that  the  individual  mandate  is  unconstitutional,  and  remanded  the  case  to  the  lower  court  to  reconsider  its  earlier  invalidation  of  the  full
Affordable Care Act. The State of California and the other plaintiffs in this case have asked the U.S. Supreme Court for authorization to appeal the decision of
the Fifth Circuit. Litigation and legislation over the ACA are likely to continue, with unpredictable and uncertain results. We will continue to evaluate the
effect that the ACA and its possible repeal and replacement has on our business. These laws may result in additional reductions in Medicare, Medicaid and
other healthcare funding, or insured patients generally, which could have a material adverse effect on our future, potential customers and, accordingly, our
financial operations.

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. As indicated previously, significant uncertainty exists regarding the future scope
and effect of current health care legislation and regulations because the current administration and federal legislators have publicly declared their intention to
significantly modify or repeal the current legislative framework. We cannot predict the initiatives that may be adopted in the future, any of which could limit
or modify the amounts that foreign, federal and state governments as well as private payors, including patients, will pay for healthcare products and services,
which could result in reduced demand for our product candidates or additional pricing pressures.

The continuing efforts of governments, insurance companies, managed care organizations and other payors of healthcare services to contain or reduce costs of
healthcare and/or impose price controls could harm our business, financial conditions and prospects and may adversely affect:

•

•

•

•

•

the demand for or utilization of 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, fees and rebates that we are required to pay; and

the availability of capital.

We expect that the ACA, as well as other healthcare reform measures that may be adopted in the future, may result in additional reductions in Medicare and
other healthcare funding, more rigorous coverage criteria, lower reimbursement, and new payment methodologies. This could lower the price that we receive
for any approved product. Any denial in coverage or reduction in reimbursement from Medicare or other government-funded programs may result in a similar
denial  or  reduction  in  payments  from  private  payors,  which  may  prevent  us  from  being  able  to  generate  sufficient  revenue,  attain  profitability  or
commercialize our product candidates, if approved.

Our employees, independent contractors, clinical investigators, CMOs, CROs, consultants, commercial partners and vendors may engage in misconduct
or other improper activities, including noncompliance with regulatory standards and requirements, which could have a material adverse effect on our
business.

We are exposed to the risk of non-compliance, fraud, misconduct or other illegal activity by our employees, independent contractors, clinical investigators,
CMOs, CROs, consultants, commercial partners and vendors. Misconduct by these parties could include intentional, reckless and/or negligent conduct that
fails to: comply with federal and state laws and those of other applicable jurisdictions; provide true, complete and accurate information to the FDA and other
similar  foreign  regulatory  bodies;  comply  with  manufacturing  standards;  comply  with  federal  and  state  data  privacy,  security,  fraud  and  abuse  and  other
healthcare laws and regulations in the U.S. and similar foreign privacy or fraudulent misconduct laws; or report financial information or data accurately; or
disclose unauthorized activities to us. If we obtain FDA approval of any of our product candidates and begin commercializing those products in the U.S., our
potential exposure under such laws will increase significantly, and our costs associated with compliance with such laws are also likely to increase. These laws
may impact, among other things, our current activities with clinical investigators and research patients, as well as proposed and future sales, marketing and
education programs. In particular, the promotion, sales and marketing of healthcare products and services, as well as

70

 
 
 
 
 
 
certain business arrangements in the healthcare industry, are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-
dealing  and  other  abusive  practices.  These  laws  and  regulations  may  restrict  or  prohibit  a  wide  range  of  pricing,  discounting,  marketing  and  promotion,
including promotion and marketing of off-label uses of our products, structuring and commission(s), certain customer incentive programs and other business
arrangements  generally.  Activities  subject  to  these  laws  also  involve  the  improper  use  of  information  obtained  in  the  course  of  clinical  trials  or  creating
fraudulent data in our preclinical studies or clinical trials, which could result in regulatory sanctions and cause serious harm to our reputation. It is not always
possible to identify and deter misconduct by employees and other third parties, and the precautions we take to detect and prevent this activity may not be
effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming
from a failure to comply with these laws or regulations. Additionally, we are subject to the risk that a person or government could allege such fraud or other
misconduct, even if none occurred. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those
actions could have a significant impact on our business, including the imposition of significant fines or other sanctions.

We may be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, false claims laws, physician payment transparency laws,
health information privacy and security laws and anti-corruption laws. If we are unable to comply, or have not fully complied, with such laws or their
relevant foreign counterparts, we could face substantial penalties.

If  we  obtain  FDA  approval  for  any  of  our  product  candidates  and  begin  commercializing  those  products  in  the  U.S.,  our  operations  may  be  directly,  or
indirectly  through  our  future,  potential  customers  and  third-party  payors,  subject  to  various  federal  and  state  fraud  and  abuse  laws,  including,  without
limitation, the federal Anti-Kickback Statute, the federal False Claims Act (“FCA”), and data privacy and physician sunshine laws and regulations. These
laws or their relevant foreign counterparts may impact, among other things, our proposed sales, marketing, and education programs and our relationships with
healthcare  providers,  physicians  and  other  parties  through  which  we  market,  sell  and  distribute  our  products  for  which  we  obtain  marketing  approval.  In
addition, we may be subject to patient privacy regulation by the federal government and the states in the U.S. as well as other jurisdictions. The laws that may
affect our ability to operate include:

•

•

the  federal  Anti-Kickback  Statute,  which  prohibits,  among  other  things,  individuals  or  entities  from  knowingly  and  willfully  soliciting,
receiving, offering or paying any remuneration (including any kickback, bribe, or certain rebates), directly or indirectly, overtly or covertly, in
cash  or  in  kind,  to  induce,  or  in  return  for,  either  the  referral  of  an  individual,  or  the  purchase,  lease,  order,  arrangement  for  or
recommendation of the purchase, lease, order, arrangement for any good, facility, item or service, for which payment may be made, in whole
or in part, under a federal healthcare program, such as the Medicare and Medicaid programs. A person or entity does not need to have actual
knowledge of the statute or specific intent to violate it in order to have committed a violation. In addition, the Affordable Care Act provides
that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim
for purposes of the federal FCA. There are a number of statutory exceptions and regulatory safe harbors protecting some common activities
from  prosecution.  Violators  are  subject  to  civil  and  criminal  fines  and  penalties,  as  well  as  imprisonment  and  exclusion  from  government
healthcare programs;

federal civil and criminal false claims laws, including, without limitation, the federal FCA, and civil monetary penalty laws which prohibit,
among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment or approval from the
federal government, including Medicare, Medicaid and other government payors, that are false or fraudulent or knowingly making, using or
causing to be made or used a false record or statement material to a false or fraudulent claim or to avoid, decrease or conceal an obligation to
pay money to the federal government, or knowingly concealing or knowingly and improperly avoiding or decreasing an obligation to pay
money  to  the  federal  government.  Manufacturers  can  be  held  liable  under  the  FCA  even  when  they  do  not  submit  claims  directly  to
government payors if they are deemed to “cause” the submission of false or fraudulent claims by, for example, promoting a product off-label.
The  FCA  also  permits  a  private  individual  acting  as  a  “whistleblower”  to  bring  civil  whistleblower  or  qui tam actions against individuals
(including biopharmaceutical manufacturers and sellers) on behalf of the federal government alleging violations of the FCA and to share in
any monetary recovery. These laws impose criminal and civil penalties on violators;

71

 
 
 
 
 
•

•

•

•

•

•

the federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) and its implementing regulations, which impose criminal
and civil liability for knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or
obtain, by means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody
or  control  of,  any  healthcare  benefit  program,  regardless  of  the  payor  (e.g.,  public  or  private)  and  knowingly  and  willfully  falsifying,
concealing or covering up by any trick or device a material fact or making any materially false statements in connection with the delivery of,
or payment for, healthcare benefits, items or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have
actual knowledge of the statute or specific intent to violate it in order to have committed a violation. HIPAA violations can lead to civil and
criminal liability;

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 (“HITECH”), and their respective
implementing regulations, which impose requirements on certain covered healthcare providers, health plans, and healthcare clearinghouses as
well  as  their  respective  business  associates  that  perform  services  for  them  that  involve  the  use,  or  disclosure  of,  individually  identifiable
health  information,  relating  to  the  privacy,  security  and  transmission  of  individually  identifiable  health  information  without  appropriate
authorization. HITECH  also  created  new  tiers  of  civil  monetary  penalties,  amended  HIPAA  to  make  civil  and  criminal  penalties  directly
applicable to business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal
courts to enforce the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions. In addition, state
and non-U.S. laws govern the privacy and security of health and other personal information in certain circumstances, many of which differ
from each other in significant ways and may not have the same effective requirements, thus complicating compliance efforts to comply with
their respective provisions;

the  U.S.  federal  physician  payment  transparency  requirements,  sometimes  referred  to  as  the  “Physician  Payments  Sunshine  Act,”  created
under  the  Affordable  Care  Act,  and  their  implementing  regulations,  which  require  manufacturers  of  drugs,  devices,  biologics  and  medical
supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to
report  annually  to  the  CMS,  information  related  to  payments  or  other  transfers  of  value  made  to  physicians  (defined  to  include  doctors,
dentists, optometrists, podiatrists and chiropractors), other healthcare providers, and teaching hospitals, as well as ownership and investment
interests held by physicians, other healthcare providers, and their immediate family members. Failure to submit required information may
result in civil monetary penalties for all payments, transfers of value or ownership or investment interests that are not timely, accurately, and
completely reported in an annual submission. Effective January 1, 2022, the U.S. federal physician transparency reporting requirements will
extend to include transfers of value made to certain non-physician providers such as physician assistants and nurse practitioners;

the Foreign Corrupt Practices Act (“FCPA”) and other laws which prohibit improper payments or offers of payments to foreign governments
and their officials and political parties by U.S. persons and issuers as defined by the statute for the purpose of obtaining or retaining business;

the Federal Food, Drug and Cosmetic Act, which prohibits, among other things, the commercialization of adulterated or misbranded drugs
and medical devices and the Public Health Service Act, which prohibits, among other things, the commercialization of biological products
unless a biologics license is in effect; and

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

72

 
 
 
 
 
 
 
The distribution of pharmaceutical products is subject to additional requirements and regulations, including extensive record-keeping, licensing, storage and
security requirements intended to prevent the unauthorized sale of pharmaceutical products.

Because of the breadth of these laws and the limited statutory exceptions and safe harbors available, it is possible that some of our business activities could be
subject to challenge under one or more of such laws.

The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare reform, especially in light
of  the  lack  of  applicable  precedent  and  regulations.  Federal  and  state  enforcement  bodies  have  recently  increased  their  scrutiny  of  interactions  between
healthcare  companies  and  healthcare  providers,  which  has  led  to  a  number  of  investigations,  prosecutions,  convictions  and  settlements  in  the  healthcare
industry. Ensuring business arrangements comply with applicable healthcare laws, as well as responding to possible investigations by government authorities,
can be time- and resource-consuming and can divert a company’s attention from the business.

As of May 25, 2018, the General Data Protection Regulation (“GDPR”) regulates the collection and use of personal data in the EU. The GDPR covers any
business, regardless of its location, that provides goods or services to residents in the EU and, thus, could incorporate our activities in EU member states. The
GDPR imposes strict requirements on controllers and processors of personal data, including special protections for “sensitive information,” which includes
health  and  genetic  information  of  individuals  residing  in  the  EU.  GDPR  grants  individuals  the  opportunity  to  object  to  the  processing  of  their  personal
information, allows them to request deletion of personal information in certain circumstances, and provides the individual with an express right to seek legal
remedies in the event the individual believes his or her rights have been violated. Further, the GDPR imposes strict rules on the transfer of personal data out
of the EU to regions that have not been deemed to offer “adequate” privacy protections, such as the U.S. currently. Failure to comply with the requirements of
the GDPR and the related national data protection laws of the EU member states, which may deviate slightly from the GDPR, may result in warning letters,
mandatory  audits  and  financial  penalties,  including  fines  of  up  to  4%  of  global  revenues,  or  20,000,000  Euro,  whichever  is  greater.  As  a  result  of  the
implementation of the GDPR, we may be required to put in place additional mechanisms ensuring compliance with the new data protection rules.

There  is  significant  uncertainty  related  to  the  manner  in  which  data  protection  authorities  will  seek  to  enforce  compliance  with  GDPR.  For  example,  it  is
unclear whether the authorities will conduct random audits of companies doing business in the EU, or act solely after complaints are filed claiming a violation
of the GDPR. The lack of compliance standards and precedent, enforcement uncertainty and the costs associated with ensuring GDPR compliance may be
onerous and adversely affect our business, financial condition, results of operations and prospects. Further, the United Kingdom’s exit from the EU, often
referred to as Brexit, has created uncertainty with regard to data protection regulation in the United Kingdom. In particular, it is unclear how data transfers to
and from the United Kingdom will be regulated, and what other aspects of EU privacy laws will be adopted, rejected or modified by the United Kingdom.

California recently enacted the California Consumer Privacy Act (“CCPA”), which creates new individual privacy rights for California consumers (as defined
in  the  law)  and  places  increased  privacy  and  security  obligations  on  entities  handling  personal  data  of  consumers  or  households.  The  CCPA  will  require
covered companies to provide certain disclosures to consumers about its data collection, use and sharing practices, and to provide affected California residents
with ways to opt-out of certain sales or transfers of personal information. The CCPA went into effect on January 1, 2020, and the California Attorney General
will  commence  enforcement  actions  against  violators  beginning  July  1,  2020.  As  currently  written,  the  CCPA  may  impact  our  business  activities.  The
California Attorney General has proposed draft regulations, which have not been finalized to date, that may further impact our business activities if they are
adopted.  The  uncertainty  surrounding  the  implementation  of  CCPA  exemplifies  the  vulnerability  of  our  business  to  the  evolving  regulatory  environment
related to personal data and protected health information.

73

 
The increasingly global nature of our business operations subjects us to domestic and foreign anti-bribery and anti-corruption laws and regulations, such as
the FCPA. Activities conducted in jurisdictions outside of the U.S. create the risk of unauthorized payments or offers of payments that are prohibited under
the  FCPA  or  comparable  laws  and  regulations.  It  is  our  policy  to  implement  safeguards  to  discourage  these  practices  by  our  employees.  However,  these
safeguards  may  ultimately  prove  ineffective,  and  our  employees,  consultants,  and  agents  may  engage  in  conduct  for  which  we  might  be  held  responsible.
Violations of the FCPA may result in severe criminal or civil sanctions, and we may be subject to other liabilities, which could negatively affect our business,
operating results and financial condition.

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations as well as other domestic and
foreign legal requirements will involve substantial costs. It is possible that governmental and enforcement authorities will conclude that our business practices
may not comply with current or future statutes, regulations or case law interpreting applicable fraud and abuse or other healthcare laws and regulations. If any
such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on
our  business,  including  the  imposition  of  significant  civil,  criminal  and  administrative  penalties,  damages,  disgorgement,  monetary  fines,  individual
imprisonment,  possible  exclusion  from  participation  in  Medicare,  Medicaid  and  other  U.S.  federal  healthcare  programs,  contractual  damages,  reputational
harm, diminished profits and future earnings, and curtailment or restructuring of our operations, as well as additional reporting obligations and oversight if we
become subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, any of which could adversely
affect our ability to operate our business and our results of operations. Any action for violation of these laws, even if successfully defended, could cause a
pharmaceutical manufacturer to incur significant legal expenses and divert management’s attention from the operation of the business. If any of the physicians
or other healthcare providers or entities with whom we expect to do business is found not to be in compliance with applicable laws, that person or entity may
be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs. Prohibitions or restrictions on
sales or withdrawal of future marketed products could materially affect business in an adverse way. In addition, the approval and commercialization of any of
our product candidates outside the U.S. will also likely subject us to foreign equivalents of the healthcare laws mentioned above, among other foreign laws.

Failure to comply with health and data protection laws and regulations could lead to government enforcement actions (which could include civil or
criminal penalties), private litigation, and/or adverse publicity and could negatively affect our operating results and business.

We and any potential collaborators may be subject to federal, state, and foreign data protection laws and regulations (i.e., laws and regulations that address
privacy and data security). In the U.S., numerous federal and state laws and regulations, including federal health information privacy laws, state data breach
notification  laws,  state  health  information  privacy  laws,  and  federal  and  state  consumer  protection  laws  (e.g.,  Section  5  of  the  Federal  Trade  Commission
Act), that govern the collection, use, disclosure and protection of health-related and other personal information could apply to our operations or the operations
of our collaborators. In addition, we may obtain health information from third parties (including research institutions from which we obtain clinical trial data)
that are subject to privacy and security requirements under HIPAA, as amended by HITECH. Depending on the facts and circumstances, we could be subject
to civil, criminal, and administrative penalties if we knowingly obtain, use, or disclose individually identifiable health information maintained by a HIPAA-
covered entity in a manner that is not authorized or permitted by HIPAA.

Compliance with U.S. and international data protection laws and regulations could require us to take on more onerous obligations in our contracts, restrict our
ability  to  collect,  use  and  disclose  data,  or  in  some  cases,  impact  our  ability  to  operate  in  certain  jurisdictions.  Failure  to  comply  with  these  laws  and
regulations  could  result  in  government  enforcement  actions  (which  could  include  civil,  criminal  and  administrative  penalties),  private  litigation,  and/or
adverse  publicity  and  could  negatively  affect  our  operating  results  and  business.  Moreover,  clinical  trial  subjects,  employees  and  other  individuals  about
whom we or our potential collaborators obtain personal information, as well as the providers who share this information with us, may limit our ability to
collect, use and disclose the information. Claims that we have violated individuals’ privacy rights, failed to comply with data protection laws, or breached our
contractual obligations, even if we are not found liable, could be expensive and time-consuming to defend and could result in adverse publicity that could
harm our business.

In the event we conduct clinical trials in the European Economic Area (“EEA”), we may be subject to additional privacy laws. The GDPR became effective
on  May  25,  2018  and  deals  with  the  processing  of  personal  data  and  on  the  free  movement  of  such  data.  The  GDPR  imposes  a  broad  range  of  strict
requirements  on  companies  subject  to  the  GDPR,  including  requirements  relating  to  having  legal  bases  for  processing  personal  information  relating  to
identifiable  individuals  and  transferring  such  information  outside  the  EEA,  including  to  the  U.S.,  providing  details  to  those  individuals  regarding  the
processing of their personal information, keeping personal information secure, having data processing agreements with third parties who process personal
information, responding to individuals’ requests to exercise their rights in respect of their personal information, reporting security breaches involving personal
data  to  the  competent  national  data  protection  authority  and  affected  individuals,  appointing  data  protection  officers,  conducting  data  protection  impact
assessments, and record-keeping. The GDPR increases substantially the penalties to which we could be subject in the event of any non-compliance, including
fines of up to 10,000,000 Euros or up to 2% of our total worldwide annual turnover for certain comparatively minor offenses, or up to 20,000,000 Euros or up
to 4% of our total worldwide annual turnover for more serious offenses. Given the new law, we face uncertainty as to the exact interpretation of the new
requirements and we may be unsuccessful in implementing all measures required by data protection authorities or courts in interpretation of the new law.

In  particular,  national  laws  of  member  states  of  the  EU  are  in  the  process  of  being  adapted  to  the  requirements  under  the  GDPR,  thereby  implementing
national laws which may partially deviate from the GDPR and impose different obligations from country to country, so that we do not expect to operate in a
uniform  legal  landscape  in  the  EU.  Also,  as  it  relates  to  processing  and  transfer  of  genetic  data,  the  GDPR  specifically  allows  national  laws  to  impose
additional and more specific requirements or restrictions, and European laws have historically differed quite substantially in this field, leading to additional
uncertainty.

In the event we conduct clinical trials in the EEA, we must also ensure that we maintain adequate safeguards to enable the transfer of personal data outside of
the EEA, in particular to the U.S., in compliance with European data protection laws. We expect that we will continue to face uncertainty as to whether our
efforts to comply with our obligations under European privacy laws will be sufficient. If we are investigated by a European data protection authority, we may
face fines and other penalties. Any such investigation or charges by European data protection authorities could have a negative effect on our existing business
and on our ability to attract and retain new clients or pharmaceutical partners. We may also experience hesitancy, reluctance, or refusal by European or multi-
national clients or pharmaceutical partners to continue to use our products and solutions due to the potential risk exposure as a result of the current (and, in
particular,  future)  data  protection  obligations  imposed  on  them  by  certain  data  protection  authorities  in  interpretation  of  current  law,  including  the  GDPR.
Such clients or pharmaceutical partners may also view any alternative approaches to compliance as being too costly, too burdensome, too legally uncertain, or
otherwise  objectionable  and  therefore  decide  not  to  do  business  with  us.  Any  of  the  foregoing  could  materially  harm  our  business,  prospects,  financial
condition and results of operations.

If  we  fail  to  comply  with  environmental,  health  and  safety,  and  laboratory  animal  welfare  laws  and  regulations,  we  could  become  subject  to  fines  or
penalties or incur costs that could harm our business.

We  are  subject  to  numerous  federal,  state  and  local  environmental,  health  and  safety,  and  laboratory  animal  welfare  laws  and  regulations.  These  legal
requirements include those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes as well
as those which regulate the care and use of animals in research. Our operations will involve research using research animals and the use of hazardous and
flammable  materials,  including  chemicals  and  biological  materials.  Our  operations  also  may  produce  hazardous  waste  products.  We  generally  anticipate
contracting with third parties for the disposal of these materials and wastes. We will not be able to eliminate the risk of contamination or injury from these
materials. In the event of contamination or injury resulting from any use by us of hazardous materials, we could be held liable for any resulting damages, and
any liability could exceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties for failure to comply with
such laws and regulations.

Although we maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from the
use of hazardous materials, this insurance may not provide adequate coverage against potential liabilities. We do not maintain insurance for environmental
liability or toxic tort claims that may be asserted against us in connection with our storage or disposal of biological, hazardous or radioactive materials.

75

 
 
In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety, and laboratory animal welfare laws and
regulations. These current or future laws and regulations may impair our research, development or production efforts. Our failure to comply with these laws
and regulations also may result in substantial fines, penalties or other sanctions.

Failure to comply with labor and employment laws and regulations could subject us to legal liability and costs, including fines or penalties, as well as
reputational damage that could harm our business.

We  are  subject  to  numerous  federal,  state  and  local  laws  and  regulations  relating  to  the  recruiting,  hiring,  compensation  and  treatment  of  employees  and
contractors. These laws and regulations cover financial compensation (including wage and hour standards), benefits (including insurance and 401K plans),
discrimination,  workplace  safety  and  health,  benefits,  and  workers’  compensation.  In  varying  degrees  and  scope,  national,  state  and  local  laws  prohibit
unfavorable or unfair treatment in the workplace of employees or candidates based on their age, gender, race, national origin, religion, disability or sexual
orientation. Disability laws also expand upon the employment rights of veterans and persons with disabilities. At a federal level, Title VII of the Civil Rights
Act of 1964 prohibit discrimination on the basis of race, color, religion, sex or national origin. The Fair Labor Standards Act establishes a national minimum
wage, guarantees “time-and-a-half” for overtime in certain jobs, and prohibits oppressive employment of minors. The Americans with Disabilities Act, as
amended, prohibits discrimination based on disability.

The Commonwealth of Massachusetts also has laws that expand on these federal laws or create additional rights for employees or obligations for employers.
For example, on July 1, 2018, the Massachusetts Equal Pay Act went into effect, which added protections employers must comply with regarding pay equity
for “comparable work”. There is currently uncertainty regarding the exact scope of these new legal limits and such uncertainty may remain for the foreseeable
future. We may face increased employment and legal costs to ensure we are complying with this law. In addition, on October 1, 2018, a new Massachusetts
non-compete law went into effect, placing additional restrictions on employers seeking to enter into non-competition agreements with employees. This law
may negatively impact our ability to prevent employees from working with direct or indirect competitors in the future and may affect our ability to retain key
talent in a competitive market.

Our failure to comply with these and other related laws could expose us to civil and, in some cases, criminal liability, including fines and penalties. Further,
government or employee claims that we have violated any of these laws, even if ultimately disproven, could result in increased expense and management
distraction, as well as have an adverse reputational impact on us.

Risks Related to Our Intellectual Property

Third-party claims of intellectual property infringement against us, our licensors or our collaborators may prevent or delay our product discovery and
development efforts.

Our commercial success depends in part on our avoiding infringement of the valid patents and proprietary rights of third parties.

Numerous U.S. and foreign issued patents and pending patent applications owned by third parties exist in the fields in which we are developing our product
candidates. As industry, government, academia and other biotechnology and pharmaceutical research expands and more patents are issued, the risk increases
that our product candidates may give rise to claims of infringement of the patent rights of others. We cannot guarantee that our technology, future product
candidates  or  the  use  of  such  product  candidates  do  not  infringe  third-party  patents.  It  is  also  possible  that  we  have  failed  to  identify  relevant  third-party
patents or applications. Because patent rights are granted jurisdiction-by-jurisdiction, our freedom to practice certain technologies, including our ability to
research, develop and commercialize our product candidates, may differ by country.

76

 
Third parties may assert that we infringe their patents or that we are otherwise employing their proprietary technology without authorization, and may sue us.
There may be third-party patents of which we are currently unaware with claims to compositions, formulations, methods of manufacture or methods of use or
treatment that cover product candidates we discover and develop. Because patent applications can take many years to issue, there may be currently pending
patent applications that 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 or the manufacture, use or sale of our product candidates infringes upon these patents. If any such third-party patents
were  held  by  a  court  of  competent  jurisdiction  to  cover  our  technologies  or  product  candidates,  the  holders  of  any  such  patents  may  be  able  to  block  our
ability to commercialize the applicable product candidate unless we obtain a license under the applicable patents, or until such patents expire or are finally
determined to be held invalid or unenforceable. Such a license may not be available on commercially reasonable terms or at all. If we are unable to obtain a
necessary license to a third-party patent on commercially reasonable terms, our ability to commercialize our product candidates may be impaired or delayed,
which could in turn significantly harm our business.

Third parties may seek to claim intellectual property rights that encompass or overlap with intellectual property that we own or license from them or others.
Legal proceedings may be initiated to determine the scope and ownership of these rights, and could result in our loss of rights, including injunctions or other
equitable  relief  that  could  effectively  block  our  ability  to  further  develop  and  commercialize  our  product  candidates.  For  example,  through  the  Caribou
License,  we  sublicense  the  rights  of  the  Regents  of  the  University  of  California  and  the  University  of  Vienna  (collectively,  “UC/Vienna”)  to  a  worldwide
patent portfolio that covers methods of use and compositions relating to engineered CRISPR/Cas9 systems for, among other things, cleaving or editing DNA
and  altering  gene  product  expression  in  various  organisms,  including  eukaryotic  cells.  We  sublicense  the  UC/Vienna  rights  to  this  portfolio  for  human
therapeutic, prophylactic and palliative uses, including companion diagnostics, except for anti-fungal and anti-microbial uses. This patent portfolio to-date
includes, for example, multiple granted, allowed, and/or allowable patent applications in the U.S., as well as granted patents from the European Patent Office,
the  United  Kingdom’s  Intellectual  Property  Office,  the  German  Patent  and  Trade  Mark  Office,  Australia’s  Intellectual  Property  agency  and  China’s
Intellectual  Property  Office,  among  others.  Because  UC/Vienna  co-own  this  portfolio  with  Dr.  Emmanuelle  Charpentier  (from  whom  we  do  not  have
sublicense rights), we refer to this co-owned worldwide patent portfolio as the UC/Vienna/Charpentier patent family. UC/Vienna could challenge Caribou’s
rights under their license agreement, including Caribou’s right to sublicense its rights to others, such as Intellia, and on what terms such a sublicense would be
granted, each of which could adversely impact our rights under our license agreement with Caribou.

Similarly, on October 17, 2018, we initiated an arbitration proceeding with JAMS against Caribou asserting that Caribou is violating the terms and conditions
of the Caribou License, as well as other contractual and legal rights, by using and seeking to license to third parties technology covered by two patent families
(described  in,  for  instance,  PCT  No.  PCT/US2016/015145  and  PCT  No.  PCT/US2016/064860,  and  related  patents  and  applications)  relating  to  specific
structural  or  chemical  modifications  of  guide  RNAs,  that  were  purportedly  invented  or  controlled  by  Caribou,  in  our  exclusive  human  therapeutic  field.
Caribou asserted that the two families of IP are outside the scope of our field of use under the license rights granted to us under the Caribou License.

On  September  26,  2019,  we  announced  that  the  arbitration  panel  issued  an  interim  award  concluding  that  both  the  structural  and  chemical  guide  RNAs
modification  technologies  were  exclusively  licensed  to  us  by  Caribou  pursuant  to  the  Caribou  License.  After  concluding  that  the  chemical  modification
technology was within the scope of our exclusive license from Caribou, the arbitration panel nevertheless noted that its decision could delay or otherwise
adversely impact the development of these modified guide RNAs as human therapeutics. It also noted that we currently are not using these modified guide
RNAs in any of our active programs. Thus, solely with respect to the particular modified guide RNAs, the arbitration panel stated that it will declare that
Caribou has an equitable “leaseback,” which it described as exclusive, perpetual and worldwide (the “Caribou Award”). The panel instructed the parties to
negotiate the terms of the Caribou Award, including Caribou’s future payments to us for the same, but the parties’ negotiations reached an impasse.

77

 
On February 6, 2020, after considering additional submissions from the parties, the panel clarified that the Caribou Award is limited to a particular on-going
Caribou program, which seeks to develop a CAR-T cell product directed at CD19. The panel instructed the parties to seek to negotiate terms based on this
scope. Accordingly, the Caribou Award will be subject to terms, including Caribou’s future payments to us to be negotiated by the parties or, if unsuccessful,
adjudicated in additional arbitration or judicial proceedings.

Pursuant to the September 2019 interim award, the Caribou Award by the panel does not include the structural guide modifications intellectual property at
issue  in  the  arbitration,  any  other  intellectual  property  exclusively  licensed  or  sublicensed  by  Caribou  to  us  under  the  Caribou  License  (including  but  not
limited to the foundational CRISPR/Cas9 intellectual property co-owned by University of California, University of Vienna and Dr. Emmanuelle Charpentier),
or any other of our intellectual property.

Upon, and subject to the terms of, a final award, which will follow further arbitration or legal proceedings, Caribou could be able to use the modified guide
RNAs  at  issue  for  CAR-T  cell  human  therapeutics  directed  at  CD19.  Either  we  or  Caribou  may  challenge  the  arbitration  panel’s  decisions  under  limited
circumstances. The additional time and legal costs associated with negotiating or arbitrating the terms of the Caribou Award, as well as its final terms, could
adversely impact our exclusive right to use the particular modified guide RNAs in dispute and enable Caribou’s ability to compete with us (or our licensees)
in the development of CAR-T cell human therapeutics directed at CD19, each of which may adversely affect our business.

In  addition,  third  parties  could  assert  that  UC/Vienna/Charpentier  do  not  have  rights  to  the  CRISPR/Cas9  technology,  or  that  any  rights  owned  by
UC/Vienna/Charpentier are limited. For example, under our sublicense from Caribou, we have rights to patent applications owned by UC/Vienna Charpentier
covering  certain  aspects  of  CRISPR/Cas9  systems  to  edit  genes  in  eukaryotic  cells,  including  human  cells  (collectively,  the  “UC/Vienna/Charpentier
eukaryotic patent family”). The Broad Institute, Massachusetts Institute of Technology, the President and Fellows of Harvard College and the Rockefeller
University (collectively, the “Broad Institute”) co-own patents and patent applications that also claim CRISPR/Cas9 systems to edit genes in eukaryotic cells
(collectively,  the  “Broad  Institute  patent  family”).  Because  the  respective  owners  of  various  UC/Vienna/Charpentier  patent  applications  and  the  Broad
Institute  patent  family  both  allege  owning  intellectual  property  claiming  overlapping  aspects  of  CRISPR/Cas9  systems  and  methods  to  edit  genes  in
eukaryotic cells, including human cells, our ability to market and sell CRISPR/Cas9-based human therapeutics may be adversely impacted depending on the
scope and actual ownership over the inventions claimed in the competing patent portfolios. On June 25, 2019, the Patent Trial and Appeal Board (“PTAB”) of
the  U.S.  Patent  and  Trademark  Office  (“USPTO”)  declared  an  interference  between  the  UC/Vienna/Charpentier  eukaryotic  patent  family  and  the  Broad
Institute patent family to determine which research group first invented the use of the CRISPR/Cas9 technology in eukaryotic cells and, therefore, is entitled
to  the  patents  covering  the  invention.  On  August  26,  2019,  the  PTAB  redeclared  the  interference  to  include  additional  UC/Vienna/Charpentier  patent
applications covering the invention that had also been found allowable by the USPTO. If it were to succeed in the interference, the Broad could seek to assert
its  issued  patents  against  us  based  on  our  CRISPR/Cas9-based  activities,  including  commercialization.  Defense  of  these  claims,  regardless  of  their  merit,
would  involve  substantial  litigation  expense,  would  be  a  substantial  diversion  of  management  and  other  employee  resources  from  our  business  and  may
impact our reputation. 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,  obtain  one  or  more  licenses  from  third  parties,  pay  royalties  or  redesign  our  infringing  products,  which  may  be
impossible  or  require  substantial  time  and  monetary  expenditure.  In  that  event,  we  could  be  unable  to  further  develop  and  commercialize  our  product
candidates, which could harm our business significantly.

In addition, other third parties, such as Vilnius University, ToolGen, Inc., MilliporeSigma (a subsidiary of Merck KGaA) and Harvard University, filed patent
applications claiming CRISPR/Cas9-related inventions around or within a year after the UC/Vienna/Charpentier application was filed and may allege that
they invented one or more of the inventions claimed by UC/Vienna/Charpentier before UC/Vienna/Charpentier. If the USPTO deems the scope of the claims
of one or more of these parties to sufficiently overlap with the allowable claims from the UC/Vienna/Charpentier application, the USPTO could declare other
interference proceedings to determine the actual inventor of such claims. If these third-parties were to prevail in their inventorship claims or obtain patent
claims  that  cover  our  product  candidates  or  related  activities  through  these  various  legal  proceedings,  then  we  could  be  prevented  from  developing  and
commercializing all or some of our products candidates unless we can obtain rights to the third-parties’ intellectual property, or avoid or invalidate it.

78

 
Third  parties  could  also  assert  patent  rights  against  us  to  seek  and  obtain  injunctive  or  other  equitable  relief,  which  could  effectively  block  our  ability  to
further  develop  and  commercialize  product  candidates.  For  example,  the  Broad  Institute  or  other  third-parties  that  own  issued  patents,  including  patents
claiming  aspects  of  the  CRISPR-Cas9  technology,  could  seek  to  assert  such  patents  against  us  claiming  that  our  activities,  including  those  relating  to  the
CRISPR-Cas9  technology,  infringe  their  respective  patents.  Defense  of  these  or  similar  claims,  regardless  of  their  merit,  would  involve  substantial  legal
expense, would be a substantial diversion of management and other employee resources from our business and may impact our reputation. 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 any adjudicated willful
infringement, obtain one or more licenses from third parties, pay royalties or redesign our infringing products, which may be impossible or require substantial
time and monetary expenditure. In that event, we may be unable to further develop and commercialize our product candidates, which could harm our business
significantly.

Third parties asserting their patent rights against us may seek and obtain injunctive or other equitable relief, which could effectively limit or block our ability
to further develop and commercialize our product candidates. If we are found to infringe a third-party’s valid intellectual property rights, we could be required
to obtain a license from such third-party to continue developing and marketing our products and technology. However, we may not be able to obtain any
required  license  on  commercially  reasonable  terms  or  at  all.  Even  if  we  were  able  to  obtain  a  license,  it  could  be  non-exclusive,  thereby  giving  our
competitors  access  to  the  same  technologies  licensed  to  us.  We  could  be  forced,  including  by  court  order,  to  cease  commercializing,  manufacturing  or
importing the infringing technology or product. In addition, we could be found liable for monetary damages, including treble damages and attorneys’ fees if
we are found to have willfully infringed a patent. A finding of infringement could prevent us from commercializing one or more of our product candidates,
force us to redesign our infringing products or force us to cease some or all of our business operations, any of which could materially harm our business and
could prevent us from further developing and commercializing our proposed future product candidates thereby causing us significant harm. Claims that we
have misappropriated the confidential information or trade secrets of third parties could have a similar negative impact on our business.

Third-party  owned  IP  relating  to  CRISPR/Cas9  or  other  related  technologies  necessary  to  develop,  manufacture  and  commercialize  viable  CRISPR/Cas9
therapeutics – such as compositions of the products or components, methods of treatment, delivery technologies, chemical modifications, and analytical and
manufacturing methods – could adversely impact our ability to ultimately market and sell products. Third parties may own intellectual property, including
patents, that cover all or aspects of our technologies and potential products, and may be necessary for us to develop or commercialize viable products. If we
are unable to successfully license, avoid or challenge such third-party intellectual property, we may not be able to develop and commercialize viable products
in all or certain jurisdictions. In addition, if the intellectual property covering our products or technologies that we own or license were to be legally impaired
or lost, we may be unable to realize sufficient financial returns to support the development or commercialization of our products.

Under our license agreement with Caribou, we sublicense a patent family from the Regents of the University of California and the University of Vienna
that is co-owned by Dr. Emmanuel Charpentier. The outcome of recent proceedings, as well as potential future proceedings, related to this patent family
may affect our ability to utilize the intellectual property sublicensed under our license agreement with Caribou.

The Broad Institute patent family includes issued patents in the U.S. and Europe that purport to cover certain aspects of the CRISPR/Cas9 genome editing
platform  for  use  on  eukaryotic  cells,  including  human  cells.  On  June  25,  2019,  the  PTAB  declared  an  interference  between  the  UC/Vienna/Charpentier
eukaryotic  patent  family  and  the  Broad  patent  family  that  claim  the  use  of  the  CRISPR/Cas9  technology  in  eukaryotic  cells,  including  human  cells.  On
August 26, 2019, the PTAB redeclared the interference to include additional UC/Vienna/Charpentier patent applications covering the invention that had also
been found allowable by the USPTO. In this interference, the PTAB will seek to determine which research group first invented the use of the technology in
eukaryotic cells and, therefore, is entitled to the patents covering the invention. If the PTAB were to conclude that UC/Vienna/Charpentier were not the first
inventors, we may not have rights to this invention, which could adversely impact our ability to develop and commercialize our product candidates. If it were
to  succeed  in  the  interference,  the  Broad  could  seek  to  assert  its  issued  patents  against  us  based  on  our  CRISPR/Cas9-based  activities,  including
commercialization. Defense of these claims, regardless of their merit, would involve substantial litigation expense,

79

 
would be a substantial diversion of management and other employee resources from our business and may impact our reputation. 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, obtain one
or  more  licenses  from  third  parties,  pay  royalties  or  redesign  our  infringing  products,  which  may  be  impossible  or  require  substantial  time  and  monetary
expenditure. In that event, we could be unable to further develop and commercialize our product candidates, which could harm our business significantly.

In addition, other third parties, such as Vilnius University, ToolGen, Inc., MilliporeSigma (a subsidiary of Merck KGaA) and Harvard University, filed patent
applications claiming CRISPR/Cas9-related inventions around or within a year after the UC/Vienna/Charpentier application was filed and may allege that
they invented one or more of the inventions claimed by UC/Vienna/Charpentier before UC/Vienna/Charpentier. If the USPTO deems the scope of the claims
of one or more of these parties to sufficiently overlap with the allowable claims from the UC/Vienna/Charpentier application, the USPTO could declare other
interference  proceedings  to  determine  the  actual  inventor  of  such  claims.  In  addition,  UC/Vienna/Charpentier  or  the  other  third  parties  could  seek  judicial
review  of  their  inventorship  claims.  If  UC/Vienna/Charpentier  fail  in  defending  their  inventorship  priority  on  any  of  these  claims,  we  may  lose  valuable
intellectual property rights, such as the exclusive right to use such intellectual property. Such an outcome could have a material adverse effect on our business.
Even  if  we  are  successful  in  defending  against  such  claims,  any  disputes  could  result  in  substantial  costs  and  be  a  distraction  to  management  and  other
employees.

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

We  may  in  the  future  be  subject  to  claims  that  former  employees,  collaborators  or  other  third  parties  have  an  interest  in  our  patents  or  other  intellectual
property as an inventor or co-inventor or other claims challenging the inventorship of our patents or ownership of our intellectual property (including patents
and intellectual property that we in-license). For example, the UC/Vienna/Charpentier patent family that is covered by our license agreement with Caribou is
co-owned by UC/Vienna and Dr. Charpentier, and our sublicense rights are derived from the first two co-owners and not from Dr. Charpentier. Therefore, our
rights to these patents are not exclusive and third parties, including competitors, may have access to intellectual property that is important to our business. In
addition,  we  may  have  inventorship  disputes  arise  from  conflicting  obligations  of  collaborators,  consultants  or  others  who  are  involved  in  developing  our
technology and product candidates. Litigation or other legal proceedings may be necessary to defend against these and other claims challenging inventorship.
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.

We  depend  on  intellectual  property  licensed  from  third  parties  and  termination  or  modification  of  any  of  these  licenses  could  result  in  the  loss  of
significant rights, which would harm our business.

We  are  dependent  on  patents,  know-how  and  proprietary  technology,  both  our  own  and  licensed  from  others,  including  Caribou,  Novartis  and  OSR.  Any
termination of these licenses, loss by our licensors of the rights they receive from others, diminution of our rights or those of our licensors, or a finding that
such intellectual property lacks legal effect, could result in the loss of significant rights and could harm our ability to commercialize any product candidates.
For example, UC/Vienna could challenge Caribou’s rights under their agreement, including Caribou’s right to sublicense its rights to others, such as Intellia,
and on what terms such a sublicense would be granted, each of which could adversely impact our rights under our agreement with Caribou. Similarly, Caribou
or other licensors, or other third parties from which we derive rights, could challenge the scope of our licensed rights or fields under our license agreement,
which could adversely impact our exclusive rights to use CRISPR/Cas9 technology in our human therapeutics field.

80

 
For  example,  as  discussed  above,  on  September  26,  2019,  we  announced  that  an  arbitration  panel  had  issued  an  interim  award  concluding  that  both  the
structural and chemical guide RNAs modification technologies were exclusively licensed to us by Caribou pursuant to the Caribou License. After concluding
that the chemical modification technology was within the scope of our exclusive license with Caribou, the arbitration panel noted that its decision could delay
or otherwise adversely impact the development of these modified guide RNAs as human therapeutics. Thus, solely with respect to the particular modified
guide RNAs, the arbitration panel stated that it will declare that Caribou has an equitable award, which it described as exclusive, perpetual and worldwide.
Upon, and subject to the terms of, a final award, which will follow further legal proceedings between the parties, Caribou could be able to use the modified
guide RNAs at issue for human therapeutics. Although the interim award has no effect on our rights or current programs nor on Caribou’s obligations under
the Caribou License, we cannot predict the potential implications and impact the interim award may have on our business.

Disputes have and may arise between us and our licensors, our licensors and their licensors, or us and third parties that co-own intellectual property with our
licensors or their licensors, regarding intellectual property subject to a license agreement, including those relating to:

•

•

•

•

•

•

•

•

•

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

whether and the extent to which our technology, products and processes infringe on, or derive from, intellectual property of the licensor that
is not subject to the license agreement;

whether  our  licensor  or  its  licensor  had  the  right  to  grant  the  license  agreement,  or  whether  they  are  compliant  with  their  contractual
obligations to their respective licensor(s);

whether third parties are entitled to compensation or equitable relief, such as an injunction, for our use of the intellectual property without
their authorization;

our right to sublicense patent and other rights to third parties, including those under collaborative development relationships;

whether  we  are  complying  with  our  obligations  with  respect  to  the  use  of  the  licensed  technology  in  relation  to  our  development  and
commercialization of product candidates;

our involvement in the prosecution, defense and enforcement of the licensed patents and our licensors’ overall patent strategy;

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

the amounts of royalties, milestones or other payments due under the license agreement.

If disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on acceptable terms,
or are insufficient to provide us the necessary rights to use the intellectual property, we may be unable to successfully develop and commercialize the affected
product candidates. If we or any such licensors fail to adequately protect this intellectual property, our ability to commercialize our products could suffer.

We depend, in part, on our licensors to file, prosecute, maintain, defend and enforce patents and patent applications that are material to our business.

Patents  relating  to  our  product  candidates  are  controlled  by  certain  of  our  licensors  or  their  respective  licensors.  Each  of  our  licensors  or  their  licensors
generally has rights to file, prosecute, maintain and defend the patents we have licensed from such licensor. If these licensors or any future licensees and in
some  cases,  co-owners  from  which  we  do  not  yet  have  licenses,  having  rights  to  file,  prosecute,  maintain,  and  defend  our  patent  rights  fail  to  adequately
conduct  these  activities  for  patents  or  patent  applications  covering  any  of  our  product  candidates,  our  ability  to  develop  and  commercialize  those  product
candidates may be adversely affected and we may not be able to prevent competitors from making, using or selling competing products. We cannot be certain
that such activities by our licensors or their respective licensors have been or will be conducted in compliance with applicable laws and regulations or in our
best interests, or will result in valid and enforceable patents or other intellectual property rights. Pursuant to the terms of the license agreements with our
licensors, the licensors may have the right to control

81

 
 
 
 
 
 
 
 
 
 
enforcement of our licensed patents or defense of any claims asserting the invalidity of these patents and, even if we are permitted to pursue such enforcement
or defense, we cannot ensure the cooperation of our licensors or, in some cases, other necessary parties, such as the co-owners of the intellectual property
from which we have not yet obtained a license. We cannot be certain that our licensors or their licensors, and in some cases, their respective co-owners, will
allocate sufficient resources or prioritize their or our enforcement of such patents or defense of such claims to protect our interests in the licensed patents. For
example, with respect to our sublicensed rights from Caribou to UC/Vienna/Charpentier intellectual property, UC retained the right to control the prosecution,
enforcement  and  defense  of  this  intellectual  property  in  its  license  agreement  with  Caribou  and,  pursuant  to  an  Invention  Management  Agreement,  shares
these  responsibilities  with  CRISPR  Therapeutics  and,  under  certain  circumstances,  ERS  Genomics,  Ltd.,  as  the  designated  managers  of  the  intellectual
property. For these reasons, UC may be unable or unwilling to prosecute certain patent claims that would be best for our product candidates, or enforce its
patent rights against infringers of the UC/Vienna/Charpentier patent family.

Even if we are not a party to legal actions or other disputes involving our licensed intellectual property, an adverse outcome could harm our business because
it might prevent us from continuing to license intellectual property that we may need to operate our business. In addition, even when we have the right to
control patent prosecution of licensed patents and patent applications, enforcement of licensed patents, or defense of claims asserting the invalidity of those
patents,  we  may  still  be  adversely  affected  or  prejudiced  by  actions  or  inactions  of  our  licensors  and  their  counsel  that  took  place  prior  to  or  after  our
assuming control.

We  may  not  be  successful  in  obtaining  or  maintaining  necessary  rights  to  product  components  and  processes  or  other  technology  for  our  product
development pipeline.

The growth of our business will likely depend in part on our ability to acquire or in-license additional proprietary rights. For example, our programs may
involve additional product candidates, delivery systems or technologies that may require the use of additional proprietary rights held by third parties. Our
ultimate product candidates may also require specific modifications or formulations to work effectively and efficiently. These modifications or formulations
may be covered by intellectual property rights held by others. We may be unable to acquire or in-license any relevant third-party intellectual property rights
that we identify as necessary or important to our business operations.

Additionally, we sometimes collaborate with 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 option, we may be unable to negotiate a license within the specified timeframe 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.

The licensing and acquisition of third-party intellectual property rights is a competitive practice and companies that may be more established, or have greater
resources than we do, may also be pursuing strategies to license or acquire third-party intellectual property rights that we may consider necessary or attractive
in order to commercialize our product candidates. More established companies may have a competitive advantage over us due to their larger size and cash
resources or greater clinical development and commercialization capabilities. There can be no assurance that we will be able to successfully complete such
negotiations and ultimately acquire the rights to the intellectual property surrounding the additional product candidates that we may seek to acquire.

If we are unable to successfully obtain rights to valid third-party intellectual property or to maintain the existing intellectual property rights we have, we may
have to abandon development of such program and our business and financial condition could suffer.

82

 
We could be unsuccessful in obtaining or maintaining adequate patent protection for one or more of our products or product candidates, or asserting and
defending our intellectual property rights that protect our products and technologies.

We anticipate that we will file additional patent applications both in the U.S. and in other countries, as appropriate. However, we cannot predict:

•

•

•

•

•

if and when any patents will issue;

the scope, degree and range of protection any issued patents will afford us against competitors, including whether third parties will find ways
to invalidate or otherwise circumvent our patents;

whether others will apply for or obtain patents claiming aspects similar to those covered by our patents and patent applications;

whether certain governments will appropriate our intellectual property rights and allow competitors to use them; or

whether we will need to initiate litigation or administrative proceedings to assert or defend our patent rights, which may be costly whether we
win or lose.

Composition of matter patents for biological and pharmaceutical products are generally considered to be the strongest form of intellectual property protection
for those types of products, as such patents provide protection without regard to any method of use. We cannot be certain, however, that any claims in our
pending or future patent applications covering the composition of matter of our product candidates will be considered patentable by the USPTO or by patent
offices in foreign countries, or that the claims in any of our ultimately issued patents will be considered valid and enforceable by courts in the U.S. or foreign
countries. Method of use patents protect the use of a product for the specified method, for example a method of treating a certain indication using a product.
This type of patent does not prevent a competitor from making and marketing a product that is identical to our product for an indication that is outside the
scope  of  the  patented  method.  Moreover,  even  if  competitors  do  not  actively  promote  their  product  for  our  targeted  indications,  physicians  may  prescribe
these products “off-label” for those uses that are covered by our method of use patents. Although off-label prescriptions may infringe or contribute to the
infringement of method of use patents, the practice is common and such infringement is difficult to prevent or prosecute.

The strength of patents in the biotechnology and pharmaceutical field can be uncertain, and evaluating the scope of such patents involves complex legal and
scientific analyses. The patent applications that we own or in-license may fail to result in issued patents with claims that cover any product candidates or uses
thereof in the U.S. or in other foreign countries.

Further,  the  patent  prosecution  process  is  expensive  and  time-consuming,  and  we  may  not  be  able  to  file  and  prosecute  all  necessary  or  desirable  patent
applications at a reasonable cost, in a timely manner, or in all jurisdictions. It is also possible that we will fail to identify patentable aspects of our research
and development output before it is too late to obtain patent protection. Moreover, in some circumstances, we do not have the right to control the preparation,
filing  and  prosecution  of  patent  applications,  or  to  maintain  the  patents,  covering  technology  that  we  license  from  third  parties.  We  may  also  require  the
cooperation of our licensors or other necessary parties, such as the co-owners of the intellectual property from which we have not yet obtained a license, in
order to enforce the licensed patent rights, and such cooperation may not be provided. Therefore, these patents and applications may not be prosecuted and
enforced in a manner consistent with the best interests of our business.

The laws of foreign countries may not protect our rights to the same extent as the laws of the U.S. and we may fail to seek or obtain patent protection in all
major markets. For example, European patent law restricts the patentability of methods of treatment of the human body more than U.S. law does. Publications
of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the U.S. and other jurisdictions are typically not
published until 18 months after filing, or in some cases not at all. Therefore, we will be unable to know with certainty whether we were the first to make any
inventions claimed in any patents or patent applications, or that we were the first to file for patent protection of such inventions, nor can we know whether
those from whom we license patents were the first to make the inventions claimed or were the first to file.

83

 
 
 
 
 
 
The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our owned and licensed patents may be challenged in the
courts  or  patent  offices  in  the  U.S.  and  abroad.  There  is  a  substantial  amount  of  litigation  as  well  as  administrative  proceedings  for  challenging  patents,
including  interference,  derivation,  and  reexamination  proceedings  before  the  USPTO  and  oppositions  and  other  comparable  proceedings  in  foreign
jurisdictions, involving patents and other intellectual property rights in the biotechnology and pharmaceutical industries, and we expect this to be true for the
CRISPR/Cas9  space  as  well.  For  example,  a  number  of  third  parties  have  filed  oppositions  challenging  the  validity,  and  seeking  the  revocation,  of  the
CRISPR/Cas9 genome editing patents granted to UC/Vienna/Charpentier by the European Patent Office to date. For example, in January 2020, the European
Patent Office (“EPO”) will hold a hearing on the various third parties’ challenges to the validity of UC/Vienna/Charpentier’s first European patent, which
covers compositions comprising Cas9 and single guide RNA molecules, as well as methods of editing DNA in vitro or ex vivo using Cas9 and single guide
RNAs.  If  UC/Vienna/Charpentier  fail  in  defending  the  validity  of  this  (or  their  other  European  patents  that  have  similarly  been  opposed),  we  may  lose
valuable intellectual property rights, such as the exclusive right to use such intellectual property. Such an outcome could have a material adverse effect on our
business  in  Europe.  In  addition,  since  the  passage  of  the  America  Invents  Act  in  2013,  U.S.  law  also  provides  for  other  procedures  to  challenge  patents,
including inter partes  reviews  and  post-grant  reviews,  that  add  uncertainty  to  the  possibility  of  challenge  to  our  developed  or  licensed  patents  and  patent
applications  in  the  future.  Furthermore,  for  U.S.  applications  in  which  all  claims  are  entitled  to  a  priority  date  before  March  16,  2013,  an  interference
proceeding can be provoked by a third-party or instituted by the USPTO to determine who was the first to invent any of the subject matter covered by the
patent claims of our applications. See the above risk factor titled “Third-party claims of intellectual property infringement against us, our licensors or our
collaborators may prevent or delay our product discovery and development efforts.”

Such challenges may result in loss of exclusivity or freedom to operate or in patent claims being narrowed, invalidated or held unenforceable, in whole or in
part, which could limit our ability to practice the invention or stop others from using or commercializing similar or identical technology and products, or limit
the duration of the patent protection of our technology and products. Given the amount of time required for the development, testing and regulatory review of
new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our owned
and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

Furthermore, even if they are unchallenged, our patents and patent applications may not adequately protect our intellectual property or prevent others from
designing  their  products  to  avoid  being  covered  by  our  claims.  If  the  breadth  or  strength  of  protection  provided  by  the  patent  applications  we  hold  is
threatened, this could dissuade companies from collaborating with us to develop, and could threaten our ability to commercialize, product candidates. Further,
if we encounter delays in our clinical trials, the period of time during which we could market product candidates under patent protection would be reduced.
Because patent applications in the U.S. and most other countries are confidential for a period of time after filing, we cannot be certain that we were the first to
file any patent application related to our product candidates.

Our  pending  and  future  patent  applications  or  the  patent  applications  that  we  obtain  rights  to  through  in-licensing  arrangements  may  not  result  in  patents
being  issued  which  protect  our  technology  or  future  product  candidates,  in  whole  or  in  part,  or  which  effectively  prevent  others  from  commercializing
competitive technologies and products. Changes in either the patent laws or interpretation of the patent laws in the U.S. and other countries may diminish the
value of our patents or narrow the scope of our patent protection.

Litigation or other administrative proceedings challenging our intellectual property, including interferences, derivation, reexamination, inter partes  reviews
and  post-grant  reviews,  may  result  in  a  decision  adverse  to  our  interests  and,  even  if  we  are  successful,  may  result  in  substantial  costs  and  distract  our
management  and  other  employees.  Furthermore,  there  could  be  public  announcement  of  the  results  of  hearings,  motions  or  other  interim  proceedings  or
developments in any proceeding challenging the issuance, scope, validity and enforceability of our developed or licensed intellectual property. If securities
analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock.

84

 
Any of these potential negative developments could impact the scope, validity, enforceability or commercial value of our patent rights and, as a result, have
material adverse effect on our business, financial condition, results of operations or prospects.

Confidentiality agreements with employees and third parties may not prevent unauthorized disclosure of trade secrets and other proprietary information.

In  addition  to  the  protection  afforded  by  patents,  we  seek  to  rely  on  trade  secret  protection  and  confidentiality  agreements  to  protect  our  proprietary  and
confidential information. We also utilize proprietary processes for which it would be difficult to enforce patents. In addition, other elements of our product
discovery and development processes involve proprietary know-how, information, or technology that is not covered by patents. Trade secrets, however, may
be  difficult  to  protect.  We  seek  to  protect  our  proprietary  processes,  in  part,  by  entering  into  confidentiality  agreements  with  our  employees,  consultants,
outside  scientific  advisors,  contractors,  and  collaborators,  and  we  also  rely  on  national  and  state  laws  requiring  our  directors,  employees,  contractors  and
collaborators  to  protect  our  proprietary  information.  Although  we  use  reasonable  efforts  to  protect  our  trade  secrets,  our  employees,  consultants,  outside
scientific  advisors,  contractors,  and  collaborators  might  intentionally  or  inadvertently  disclose  our  trade  secret  information  to  competitors.  In  addition,
competitors may otherwise gain access to our trade secrets or independently develop substantially equivalent information and techniques. Furthermore, 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  U.S.  As  a  result,  we  may
encounter significant problems in protecting and defending our intellectual property both in the U.S. and abroad. If we are unable to prevent unauthorized
material  disclosure  of  our  intellectual  property  to  third  parties,  or  misappropriation  of  our  intellectual  property  by  third  parties,  we  may  not  be  able  to
establish or maintain a competitive advantage in our market, which could materially adversely affect our business, operating results, and financial condition.

We have limited foreign intellectual property rights and may not be able to protect our intellectual property rights throughout the world.

We  have  limited  intellectual  property  rights  outside  the  U.S.  Filing,  prosecuting,  maintaining  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 U.S. can have a different scope and
strength  than  do  those  in  the  U.S.  In  addition,  the  laws  of  some  foreign  countries,  such  as  China,  Brazil,  Russia,  India  and  South  Africa,  do  not  protect
intellectual property rights to the same extent as federal and state laws in the U.S. Consequently, we may not be able to prevent third parties from practicing
our inventions in all countries outside the U.S., or from selling or importing products made using our inventions in and into the U.S. 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 rights are not as strong as those in the U.S. These products may
compete with our products and our patents or other intellectual property rights may not be effective or adequate to prevent them from competing. In addition,
in jurisdictions outside the U.S., a license may not be enforceable unless all the owners of the intellectual property agree or consent to the license. Further,
patients may choose to travel to countries in which we do not have intellectual property rights or which do not enforce these rights to obtain the products or
treatment from competitors in such countries.

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of
certain countries, such as China, Brazil, Russia, India and South Africa, do not favor the enforcement of patents, trade secrets and other intellectual property,
particularly  those  relating  to  biopharmaceutical  products,  which  could  make  it  difficult  in  those  jurisdictions  for  us  to  stop  the  infringement  or
misappropriation of our patents or other intellectual property rights, or the marketing of competing products in violation of our proprietary rights. Proceedings
to enforce our patent and other intellectual property rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from
other aspects of our business. Furthermore, such proceedings could put our patents at risk of being invalidated, held unenforceable, or interpreted narrowly,
could put our patent applications at risk of not issuing, and could provoke third parties to assert claims of infringement or misappropriation 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.

85

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

Competitors  may  infringe  our  patents  or  the  patents  of  our  licensors.  To  cease  such  infringement  or  unauthorized  use,  we  may  be  required  to  file  patent
infringement claims, which can be expensive and time-consuming. In addition, in an infringement proceeding or a declaratory judgment action against us, a
court may decide that one or more of our patents is not valid or is unenforceable, 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 proceeding could put one or more of our
patents at risk of being invalidated, held unenforceable or interpreted narrowly and could put our patent applications at risk of not issuing. 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.

Interference  or  derivation  proceedings  provoked  by  third  parties  or  brought  by  the  USPTO  may  be  necessary  to  determine  the  priority  of  inventions  with
respect to, or the correct inventorship of, our patents or patent applications or those of our licensors. An unfavorable outcome could result in a loss of our
current patent rights and 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. Litigation, interference or derivation proceedings may
result in a decision adverse to our interests and, even if we are successful, may result in substantial costs and distract our management and other employees.

Further, if a party to our licenses, either a licensee or licensor, were to breach or challenge our rights under the relevant license agreement (or if one of our
licensor’s own licensors were to challenge our licensor’s rights), we may have to initiate or participate in a legal proceeding to enforce our rights. Any such
legal  proceeding  could  be  expensive  and  time-consuming.  In  addition,  if  a  court  or  other  tribunal  were  to  rule  against  us,  we  could  lose  key  intellectual
property and financial rights. Pursuing or defending against these legal claims, regardless of merits, would involve substantial legal expense and would be a
substantial  diversion  of  employee  resources  from  our  business.  Furthermore,  because  of  the  substantial  amount  of  discovery  required  in  connection  with
intellectual property litigation or contractual litigation there is a risk that some of our confidential information could be compromised by disclosure during
this  type  of  litigation  or  proceeding.  In  addition,  there  could  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 substantial adverse effect on the price of our common
stock. For example, as discussed above, on September 26, 2019, we announced that an arbitration panel had issued an interim award concluding that both the
structural and chemical guide RNAs modification technologies were exclusively licensed to us by Caribou pursuant to the Caribou License. Nevertheless, the
arbitration panel noted that its decision could delay or otherwise adversely impact the development of these modified guide RNAs as human therapeutics.
Thus, solely with respect to the particular modified guide RNAs, the arbitration panel stated that it will declare that Caribou has an equitable award, which it
described as exclusive, perpetual and worldwide. Upon, and subject to the terms of, a final award, which will follow further legal proceedings between the
parties, Caribou could be able to use the modified guide RNAs at issue to develop engineered CAR-T’s directed at CD19 as human therapeutics. Although the
interim  award  has  no  effect  on  our  rights  or  current  programs  nor  on  Caribou’s  obligations  under  the  Caribou  License,  we  cannot  predict  the  potential
implications and impact the interim award may have.

Issued  patents  covering  our  product  candidates  could  be  found  invalid  or  unenforceable  if  challenged  in  court  or  before  the  USPTO  or  comparable
foreign authority.

If we or one of our licensing partners initiate 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  or  unenforceable.  In  patent  litigation  in  the  U.S.,  defendant  counterclaims
alleging invalidity or unenforceability are commonplace, and there are numerous grounds upon which a third-party can assert invalidity or unenforceability of
a patent. Third parties may also raise similar claims before administrative bodies in the U.S. or other jurisdictions, even outside the context of litigation. Such
mechanisms  include  re-examination,  inter  partes  review,  post-grant  review  and  equivalent  proceedings  in  foreign  jurisdictions,  such  as  opposition  or
derivation proceedings. Such proceedings could result in revocation or amendment to our patents in such a way that they no longer cover and protect our
product candidates. The outcome following legal assertions of invalidity and unenforceability is unpredictable. With respect to the validity of our patents, for
example, we cannot be certain that there is no

86

 
invalidating prior art of which we, our patent counsel, and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal
assertion of invalidity, unpatentability and/or unenforceability, we would lose at least part, and perhaps all, of the patent protection on our product candidates.
For example, various third parties have filed challenges to the validity of UC/Vienna/Charpentier’s European patents, which cover compositions comprising
Cas9 and gRNA molecules, as well as methods of editing DNA in vitro or ex vivo using Cas9 and gRNAs. If UC/Vienna/Charpentier fail in defending the
validity of these patents, we may lose valuable intellectual property rights, such as the exclusive right to use such intellectual property. Such an outcome could
have a material adverse effect on our business in Europe.

We  may  be  subject  to  claims  that  our  employees,  directors,  consultants,  or  independent  contractors  have  wrongfully  used  or  disclosed  confidential
information of third parties.

We  have  received  confidential  and  proprietary  information  from  third  parties.  In  addition,  we  employ  individuals  who  were  previously  employed  at  other
biotechnology  or  pharmaceutical  companies  as  well  as  academic  research  institutions.  We  may  be  subject  to  claims  that  we  or  our  employees,  directors,
consultants, or independent contractors have inadvertently or otherwise used or disclosed confidential information of these third parties or our employees’
former employers. Litigation may be necessary to defend against these claims, which could result in money damages or a judicial order prohibiting the use of
certain intellectual property. Even if we are successful in defending against these claims, litigation could result in substantial cost and be a distraction to our
management and 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 on any issued patent are due to be paid to the USPTO and foreign patent agencies in several stages over the lifetime of the patent.
The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar
provisions during the patent application process. Although an inadvertent lapse can in many cases be cured by payment of a late fee or by other means in
accordance  with  the  applicable  rules,  there  are  situations  in  which  noncompliance  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. Noncompliance events that could result in abandonment or lapse of a patent or
patent application include failure to respond to official actions within prescribed time limits, non-payment of fees, and failure to properly legalize and submit
formal documents. In any such event, our competitors might be able to enter the market, which would have a material adverse effect on our business.

We may be required to pay certain milestones and royalties under our license agreements with third-party licensors.

Under our current and future license agreements, we may be required to pay milestones and royalties based on our revenues, including sales revenues of our
products, utilizing the technologies licensed or sublicensed from third parties, including Caribou, Novartis, Regeneron and OSR, and these milestones and
royalty payments could adversely affect our ability to research, develop and obtain approval of product candidates, as well as the overall profitability for us of
any products that we may seek to commercialize. In order to maintain our license rights under these license agreements, we will need to meet certain specified
milestones, subject to certain cure provisions, in the development of our product candidates. Further, our licensors (or their licensors) or licensees may dispute
the terms, including amounts, that we are required to pay under the respective license agreements. If these claims were to result in a material increase in the
amounts that we are required to pay to our licensors, or in a claim of breach of the license, our ability to research, develop and obtain approval of product
candidates, or to commercialize products, could be significantly impaired.

In addition, these agreements contain diligence milestones and we may not be successful in meeting all of the milestones in the future on a timely basis or at
all.  We  will  need  to  outsource  and  rely  on  third  parties  for  many  aspects  of  the  clinical  development,  sales  and  marketing  of  our  products  covered  under
our  license  agreements.  Delay  or  failure  by  these  third  parties  could  adversely  affect  the  continuation  of  our  license  agreements  with  their  third-party
licensors.

87

 
If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our
business may be adversely affected.

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business
may be adversely affected. Our unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to be
infringing on other marks. We may not be able to protect our rights to these trademarks and trade names, which we need to build name recognition among
potential partners or future, potential customers in our markets of interest. At times, competitors may adopt trade names or trademarks similar to ours, thereby
impeding  our  ability  to  build  brand  identity  and  possibly  leading  to  market  confusion.  In  addition,  there  could  be  potential  trade  name  or  trademark
infringement  claims  brought  by  owners  of  other  registered  trademarks  or  trademarks  that  incorporate  variations  of  our  unregistered  trademarks  or  trade
names. Over the long term, if we are unable to successfully register our trademarks and trade names and establish name recognition based on our trademarks
and trade names, then we may not be able to compete effectively and our business may be adversely affected. Our efforts to enforce or protect our proprietary
rights related to trademarks, trade secrets, domain names, copyrights or other intellectual property may be ineffective and could result in substantial costs and
diversion of resources and could adversely impact our financial condition or results of operations.

Risks Related to Our Common Stock

An active trading market for our common stock may not be sustained.

In May 2016, we closed our initial public offering. Prior to this offering, there was no public market for our common stock. Although we have completed our
initial public offering and shares of our common stock are listed and trading on the Nasdaq Global Market, an active trading market for our shares may not be
sustained. If an active market for our common stock does not continue, it may be difficult for our stockholders to sell their shares without depressing the
market price for the shares or sell their shares at or above the prices at which they acquired their shares or sell their shares at the time they would like to sell.
Any inactive trading market for our common stock may also impair our ability to raise capital to continue to fund our operations by selling shares and may
impair our ability to acquire other companies or technologies by using our shares as consideration.

The price of our common stock historically has been volatile, which may affect the price at which you could sell any shares of our common stock.

The  market  price  for  our  common  stock  historically  has  been  highly  volatile  and  could  continue  to  be  subject  to  wide  fluctuations  in  response  to  various
factors. This volatility may affect the price at which you could sell the shares of our common stock, and the sale of substantial amounts of our common stock
could  adversely  affect  the  price  of  our  common  stock.  Our  stock  price  is  likely  to  continue  to  be  volatile  and  subject  to  significant  price  and  volume

sales of a substantial number of shares of our common stock in the public market, or the perception in the market that the holders of a large
number of shares intend to sell shares;

changes in the structure of healthcare payment systems;

market conditions in the pharmaceutical and biotechnology sectors;

public perception of the safety of genome editing based therapeutics;

general economic, industry and market conditions; and

the other factors described in this Risk Factors section.

In addition, companies trading in the stock market in general, and in the Nasdaq Global Market in particular, have experienced extreme price and volume
fluctuations  that  have  often  been  unrelated  or  disproportionate  to  the  operating  performance  of  these  companies.  Broad  market  and  industry  factors  may
negatively  affect  the  market  price  of  our  common  stock,  regardless  of  our  actual  operating  performance.  In  the  past,  following  periods  of  volatility  in  the
market, securities class-action litigation has often been instituted against companies. Such litigation, if instituted against us, could result in substantial costs
and diversion of management’s attention and resources, which could materially and adversely affect our business, financial condition, results of operations
and growth prospects.

Our  principal  stockholders  and  management  own  a  significant  percentage  of  our  stock  and,  if  they  choose  to  act  together,  will  be  able  to  control  or
exercise significant influence over matters subject to stockholder approval.

As  of  December  31,  2019,  our  executive  officers,  directors,  5%  or  greater  stockholders  and  their  affiliates  beneficially  owned  approximately  63%  of  our
outstanding  voting  stock.  These  stockholders  may  have  the  ability  to  influence  us  through  their  ownership  positions.  These  stockholders  may  be  able  to
determine  all  matters  requiring  stockholder  approval.  For  example,  these  stockholders,  acting  together,  may  be  able  to  control  elections  of  directors  or
approval of any merger, sale of assets or other major corporate transaction. This may prevent or discourage unsolicited acquisition proposals or offers for our
common stock that you may believe are in your best interest as one of our stockholders.

We have broad discretion over the use of our cash and cash equivalents and may not use them effectively.

Our management has broad discretion to use our cash and cash equivalents to fund our operations and could spend these funds in ways that do not improve
our results of operations or enhance the value of our common stock. The failure by our management to apply these funds effectively could result in financial
losses that could have a material adverse effect on our business, cause the price of our common stock to decline and delay the development of our product
candidates. Pending our use to fund operations, we may invest our cash and cash equivalents in a manner that does not produce income or that loses value.

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 stockholders and could cause our stock price to fall.

We  will  need  additional  capital  in  the  future  to  continue  our  planned  operations  in  addition  to  the  proceeds  we  received  from  our  initial  public  offering
(“IPO”) in May 2016 and follow-on public offering in November 2017. 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.

On October 12, 2018, we filed a Shelf Registration Statement on Form S-3 (the “2018 Shelf”) with the SEC in relation to the registration of common stock,
preferred stock, warrants and units of any combination thereof for the purposes of selling, from time to time, our common stock, convertible securities or
other equity securities in one or more offerings. We also simultaneously entered into an Open Market Sale Agreement (the “2018 Sales  Agreement”)  with
Jefferies LLC (the “Sales Agent”), to provide for the offering, issuance and sale of up to an aggregate amount of $100.0 million of our common stock from
time to time in “at-the-market” offerings under the 2018 Shelf and subject to the limitations thereof. We have paid the Sales Agent cash commissions of 3.0%
of the gross proceeds of sales of common stock under the 2018 Sales Agreement. In November 2018, we issued 1,659,300 shares of our common stock at
$18.00 per share in accordance with the 2018 Sales Agreement for net proceeds of $28.5 million, after payment of cash commissions to the Sales Agent and
approximately $0.4 million related to legal, accounting and other fees in connection with the sales. During the twelve months ended December 31, 2019, we
issued an additional 4,231,348 shares of our common stock, in a series of sales, at an average price of $16.57 per share, in accordance with the 2018 Sales
Agreement, for aggregate net proceeds of $67.8 million,  after  payment  of  cash  commissions  to  the  Sales  Agent  and  approximately $0.2 million related to
legal, accounting and other fees in connection with the sales. As of December 31, 2019, there were no shares of common stock eligible for sale under the
2018 Sales Agreement.

On  August  23,  2019,  we  filed  a  Registration  Statement  on  Form  S-3,  as  amended  (the  “2019  Shelf”)  with  the  SEC,  which  was  declared  effective  on
September  12,  2019  (File  No.  333-233448)  in  relation  to  the  registration  of  common  stock,  preferred  stock,  debt  securities,  warrants  and  units  of  any
combination thereof. We also simultaneously entered into an Open Market Sale Agreement (the “2019 Sales Agreement”) with the Sales Agent, to provide for
the offering, issuance and sale of up to an aggregate amount of $150.0 million of our common stock from time to time in “at-the-market” offerings under the
2019 Shelf and subject to the limitations thereof. We will pay to the Sales Agent cash commissions of 3.0% of the gross proceeds of sales of common stock
under the 2019 Sales Agreement. In December 2019, we issued 287,231 shares of our common stock at an average price of $16.48 per share in accordance
with the 2019 Sales Agreement for aggregate net proceeds of $4.4 million, after payment of cash commissions to the Sales Agent and approximately $0.2
million related to legal, accounting and other fees in connection with the sales. In addition, sales of a substantial number of shares of our outstanding common
stock in the public market could occur at any time. These sales, or the perception in the market that the holders of a large number of shares of common stock
intend to sell shares, could reduce the market price of our common stock. Persons who were our stockholders prior to our IPO continue to hold a substantial
number  of  shares  of  our  common  stock  that  many  of  them  are  now  able  to  sell  in  the  public  market.  Significant  portions  of  these  shares  are  held  by  a
relatively  small  number  of  stockholders.  Sales  by  our  stockholders  of  a  substantial  number  of  shares,  or  the  expectation  that  such  sales  may  occur,  could
significantly reduce the market price of our common stock.

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us difficult, limit attempts by our stockholders
to replace or remove our current management and adversely affect our stock price.

Provisions  of  our  certificate  of  incorporation  and  by-laws  may  delay  or  discourage  transactions  involving  an  actual  or  potential  change  in  our  control  or
change  in  our  management,  including  transactions  in  which  stockholders  might  otherwise  receive  a  premium  for  their  shares,  or  transactions  that  our
stockholders might otherwise deem to be in their best interests. Therefore, these provisions could adversely affect the price of our stock. Among other things,
the certificate of incorporation and by-laws:

•

•

•

•

•

permit  the  board  of  directors  to  issue  up  to  5,000,000  shares  of  preferred  stock,  with  any  rights,  preferences  and  privileges  as  they  may
designate;

provide that the authorized number of directors may be changed only by resolution of the board of directors;

provide that all vacancies, including newly created directorships, may, except as otherwise required by law, be filled by the affirmative vote
of a majority of directors then in office, even if less than a quorum;

divide the board of directors into three classes;

provide that a director may only be removed from the board of directors by the stockholders for cause;

90

 
 
 
 
 
 
•

•

•

•

•

•

require that any action to be taken by our stockholders must be effected at a duly called annual or special meeting of stockholders, and may
not be taken by written consent;

provide that stockholders seeking to present proposals before a meeting of stockholders or to nominate candidates for election as directors at
a meeting of stockholders must provide notice in writing in a timely manner, and meet specific requirements as to the form and content of a
stockholder’s notice;

prevent cumulative voting rights (therefore allowing the holders of a plurality of the shares of common stock entitled to vote in any election
of directors to elect all of the directors standing for election, if they should so choose);

require that, to the fullest extent permitted by law, a stockholder reimburse us for all fees, costs and expenses incurred by us in connection
with  a  proceeding  initiated  by  such  stockholder  in  which  such  stockholder  does  not  obtain  a  judgment  on  the  merits  that  substantially
achieves the full remedy sought;

provide that special meetings of our stockholders may be called only by the chairman of the board, our chief executive officer (or president,
in the absence of a chief executive officer) or by the board of directors; and

provide that stockholders will be permitted to amend the bylaws only upon receiving at least two-thirds of the total votes entitled to be cast
by holders of all outstanding shares then entitled to vote generally in the election of directors, voting together as a single class.

In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which
generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any “interested” stockholder for a period of
three years following the date on which the stockholder became an “interested” stockholder.

Our certificate of incorporation and by-laws provide that the Court of Chancery of the State of Delaware will be the exclusive forum for certain disputes
between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors,
officers or employees.

Our certificate of incorporation and by-laws provide that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the
State of Delaware is the sole and exclusive forum for any state law claims for any derivative action or proceeding brought on our behalf alleging state law
claims, any action asserting a breach of fiduciary duty, any action asserting a claim against us arising pursuant to the Delaware General Corporation Law, our
certificate of incorporation or our by-laws, any action to interpret, apply, enforce, or determine the validity of our certificate of incorporation or bylaws, or
any action asserting a claim against us that is governed by the internal affairs doctrine. The choice of forum provision does not apply to claims arising under
the  Exchange  Act  or  the  Securities  Act.  The  choice  of  forum  provision  may  impose  additional  litigation  costs  on  stockholders  in  pursuing  the  claims
identified  above,  particularly  if  the  stockholders  do  not  reside  in  or  near  the  State  of  Delaware.  Additionally,  the  choice  of  forum  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  such  lawsuits  against  us  and  our  directors,  officers  and  other  employees.  Alternatively,  if  a  court  were  to  find  the  choice  of  forum  provision
contained  in  our  certificate  of  incorporation  and  by-laws  to  be  inapplicable  or  unenforceable  in  an  action,  we  may  incur  additional  costs  associated  with
resolving  such  action  in  other  jurisdictions,  which  could  adversely  affect  our  business  and  financial  condition.  The  Court  of  Chancery  of  the  State  of
Delaware may also reach different judgments or results than would other courts, including courts where a stockholder considering an action may be located or
would otherwise choose to bring the action, and such judgments may be more or less favorable to us than our stockholders.

91

 
 
 
 
 
 
 
We  incur  significant  costs  as  a  result  of  operating  as  a  public  company,  and  our  management  is  required  to  devote  substantial  time  to  compliance
initiatives and corporate governance practices.

As a public company, and particularly since we are no longer an “emerging growth company” under applicable SEC regulations, we incur significant legal,
accounting and other expenses. The Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements
of the Nasdaq Global Market and other applicable securities rules and regulations impose various requirements on public companies, including establishment
and maintenance of effective disclosure and financial controls and corporate governance practices. Our management and other personnel devote a substantial
amount of time to these compliance initiatives.

Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002 (“Section 404”), we are required to furnish a report by our management on our internal control
over financial reporting, including an attestation report on internal control over financial reporting issued by our independent registered public accounting
firm. We conduct a process each year to document and evaluate our internal control over financial reporting, which is both costly and challenging. In this
regard, we dedicate internal resources, engage outside consultants and adopt a detailed work plan to assess and document the adequacy of internal control
over financial reporting, continue steps to improve control processes as appropriate, validate through testing that controls are functioning as documented and
implement a continuous reporting and improvement process for internal control over financial reporting. Despite our efforts, there is a risk that neither we nor
our  independent  registered  public  accounting  firm  will  be  able  to  conclude  that  our  internal  control  over  financial  reporting  is  effective  as  required  by
Section  404.  This  could  result  in  an  adverse  reaction  in  the  financial  markets  due  to  a  loss  of  confidence  in  the  reliability  of  our  consolidated  financial
statements.

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.
Securities  and  industry  analysts  may  not  publish  an  adequate  amount  of  research  on  us,  which  may  negatively  impact  the  trading  price  for  our  stock.  In
addition, if one or more of the analysts who cover us downgrade our stock or publish inaccurate or unfavorable research about our business, our stock price
would  likely  decline.  Further,  if  our  operating  results  fail  to  meet  the  forecasts  of  analysts,  our  stock  price  would  likely  decline.  If  one  or  more  of  these
analysts cease coverage of us 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.

Because  we  do  not  anticipate  paying  any  cash  dividends  on  our  capital  stock  in  the  foreseeable  future,  capital  appreciation,  if  any,  will  be  your  sole
source of gain.

We have never declared or paid cash dividends on our capital stock. We currently intend to retain all of our future earnings, if any, to finance the growth and
development of our business. In addition, the terms of any future debt agreements may preclude us from paying dividends. As a result, capital appreciation, if
any, of our common stock will be your sole source of gain for the foreseeable future. 

We could be subject to significant legal proceedings which may adversely affect our results of operations or financial condition.

We are subject to the risk of litigation, derivative claims, securities class actions, regulatory and governmental investigations and other proceedings, including
proceedings arising from investor dissatisfaction with us or our performance. In the past, securities class action litigation has often been brought against a
company following a decline in the market price of its securities. This risk is especially relevant for us because biotechnology and pharmaceutical companies
have experienced significant stock price volatility in recent years. In addition, if any individuals acting on our behalf fails to satisfy his or her relevant legal or
contractual  duties,  we  could  have  liability  to  third-parties,  including  the  government  or  investors.  If  any claims were brought against us and resulted in a
finding of substantial legal liability, the finding could materially adversely affect our business, financial condition or results of operations or cause significant
reputational harm to us, which could seriously adversely impact our business. Allegations of improper conduct by private litigants or regulators, regardless of
veracity, also may harm our reputation and adversely impact our ability to grow our business. If we face such litigation, it could result in substantial costs and
a diversion of management’s attention and resources, which could harm our business.

92

 
Changes in tax law may adversely affect our business and financial condition.

The laws and rules dealing with U.S. federal, state and local income taxation are routinely being reviewed and modified by governmental bodies, officials and
regulatory agencies, including the Internal Revenue Service and the U.S. Treasury Department. Since we were founded in 2014, many such changes have
been made and changes are likely to continue to occur in the future. It cannot be predicted whether, when, in what form, or with what effective dates, tax
laws, regulations and rulings may be enacted, promulgated or issued, that could result in an increase in our or our shareholders’ tax liability.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

We have incurred substantial losses during our history and do not expect to become profitable in the near future, and we may never achieve profitability. To
the extent that we continue to generate taxable losses, unused losses will carry forward to offset future taxable income, if any, until such unused losses expire.
As of December 31, 2019, we had federal and state NOLs of $229.9 million and $236.8 million, respectively, which begin to expire in 2034. As of December
31, 2019, we had federal and state research and development and other credit carryforwards of approximately $12.6 million and $8.7 million, which begin to
expire in 2035 and 2031, respectively. Under Sections 382 and 383 of the Code, if a corporation undergoes an “ownership change,” generally defined as a
greater than 50 percentage point change (by value) in its equity ownership by certain stockholders over a three-year period, the corporation’s ability to use its
pre-change NOLs, and other pre-change tax attributes (such as research and development tax credits) to offset its post-change income or taxes may be limited.
We may have experienced ownership changes in the past and may experience ownership changes in the future as a result of our initial public offering in May
of 2016, follow-on offerings and/or subsequent shifts in our stock ownership (some of which shifts are outside our control). As a result, if we earn net taxable
income, our ability to use our pre-change NOLs and research and development tax credits to offset such taxable income and income tax, respectively, could
be subject to limitations. Similar provisions of state tax law may also apply. As a result, even if we attain profitability, we may be unable to use a material
portion of our NOLs and other tax attributes. NOLs generated in taxable years ending after December 31, 2017 are not subject to expiration.

Properties

Our  headquarters  are  located  at  40  Erie  Street  in  Cambridge,  Massachusetts,  where  we  occupy  approximately  65,000  square  feet  of  office  and  laboratory
space. We have a ten year lease agreement expiring in September 2026, with an option to terminate the lease at the end of the sixth year and an option to
extend the term of the lease for an additional three years. In addition, we lease and sublease approximately 24,000 square feet of office and laboratory space at
130 Brookline Street in Cambridge, Massachusetts, which expire in 2025 and 2021, respectively.

Item 3.

Legal Proceedings

In  the  ordinary  course  of  business,  we  are  from  time  to  time  involved  in  lawsuits,  claims,  investigations,  proceedings,  and  threats  of  litigation  related  to
intellectual property (“IP”), commercial arrangements and other matters, including the matter described below. The outcome of any such legal proceedings,
regardless of the merits, is inherently uncertain. In addition, litigation and related matters are costly and may divert the attention of our management and other
resources that would otherwise be engaged in other activities. If we were unable to prevail in any such legal proceedings, our business, results of operations,
liquidity and financial condition could be adversely affected.

Caribou Intellectual Property Arbitration

On  September  26,  2019,  we  announced  that  the  arbitration  panel  issued  an  interim  award  concluding  that  both  the  structural  and  chemical  guide  RNAs
modification technologies were exclusively licensed to us by Caribou Biosciences, Inc. (“Caribou”) pursuant to the 2014 license agreement with Caribou (the
“Caribou License”). After concluding that the chemical modification technology was within the scope of our exclusive license from Caribou, the arbitration
panel nevertheless noted that its decision could delay or otherwise adversely impact the development of these modified guide RNAs as human therapeutics. It
also noted that we currently are not using these modified guide RNAs in any of our active programs. Thus, solely with respect to the particular modified guide
RNAs, the arbitration panel stated that it will declare that Caribou has an equitable “leaseback”, which it described as exclusive, perpetual and worldwide (the
“Caribou Award”). The panel instructed the parties to negotiate the terms of the Caribou Award, including Caribou’s future payments to us for the same, but
the parties’ negotiations reached an impasse.

On February 6, 2020, after considering additional submissions from the parties, the panel clarified that the Caribou Award is limited to a particular on-going
Caribou program, which seeks to develop a CAR-T product directed at CD19. The panel instructed the parties to seek to negotiate terms based on this scope.
Accordingly,  the  Caribou  Award  will  be  subject  to  terms,  including  Caribou’s  future  payments  to  us  to  be  negotiated  by  the  parties  or,  if  unsuccessful,
adjudicated in additional arbitration or judicial proceedings.

Pursuant  to  the  September  2019  interim  award,  the  Caribou  Award  by  the  panel  does  not  include  the  structural  guide  modifications  IP  at  issue  in  the
arbitration,  any  other  IP  exclusively  licensed  or  sublicensed  by  Caribou  to  us  under  the  Caribou  License  (including  but  not  limited  to  the  foundational
CRISPR/Cas9 IP co-owned by the Regents of the University of California, University of Vienna and Dr. Emmanuelle Charpentier), or any other of our IP.

Upon, and subject to the terms of, a final award, which will follow further arbitration or legal proceedings, Caribou could be able to use the modified guide
RNAs  at  issue  for  CAR-T  cell  human  therapeutics  directed  at  CD19.  Either  we  or  Caribou  may  challenge  the  arbitration  panel’s  decisions  under  limited
circumstances.

Other than with regards to the technologies in dispute, the interim award has no effect on our rights or Caribou’s obligations under the Caribou License. The
interim award has no impact on any of our current programs, although it could impact the 2014 Novartis Agreement.

Item 5.

Market for the Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Our common stock is traded on the Nasdaq Global Market under the symbol “NTLA”.

As of February 21, 2020, the number of holders of record of our common stock was 22. The actual number of holders of our common stock is greater than
this number of record holders, and includes stockholders who are beneficial owners, but whose shares are held in street name by brokers or held by other
nominees. This holders of record number also does not include stockholders whose shares may be held in trust by other entities.

Dividends

We  have  never  declared  or  paid  cash  dividends  on  our  capital  stock.  We  intend  to  retain  all  of  our  future  earnings,  if  any,  to  finance  the  growth  and
development of our business. We do not intend to pay cash dividends to our stockholders in the foreseeable future.

Stock Performance Graph

The following graph shows a comparison from May 6, 2016, the first date that shares of our common stock were publicly traded, through December 31, 2019,
of  the  cumulative  total  return  on  an  assumed  investment  of  $100.00  in  cash  in  our  common  stock,  the  Nasdaq  Composite  Index  and  the  Nasdaq
Biotechnology Index for the same period. Such returns are based on historical results and are not intended to suggest future performance. Data for the Nasdaq
Composite Index and the Nasdaq Biotechnology Index assume reinvestment of dividends.

The performance graph in this Item 5 is not deemed to be “soliciting material” or to be “filed” with the Securities and Exchange Commission for purposes of
Section  18  of  the  Securities  and  Exchange  Act  of  1934,  as  amended,  or  otherwise  subject  to  the  liabilities  under  that  Section,  and  shall  not  be  deemed
incorporated by reference into any of our filings under the Securities Act of 1933 or the Securities Exchange Act of 1934, except to the extent we specifically
incorporate it by reference into such a filing.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

Our management’s discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements included
in this Annual Report on Form 10-K, which have been prepared by us in accordance with United States (“U.S.”) generally accepted accounting principles
(“GAAP”), and with Regulation S-X promulgated under the Securities Exchange Act of 1934, as amended. This discussion and analysis should be read in
conjunction  with  these  consolidated  financial  statements  and  the  notes  thereto  included  elsewhere  in  this  Annual  Report  on  Form  10-K.  Some  of  the
information contained in this discussion and analysis or set forth elsewhere in this Annual Report on Form 10-K, including information with respect to our
plans  and  strategy  for  our  business,  includes  forward-looking  statements  that  involve  risks  and  uncertainties.  As  a  result  of  many  factors,  including  those
factors set forth in Part I, Item 1A. Risk Factors of this Annual Report on Form 10-K, our actual results could differ materially from the results described in or
implied by the forward-looking statements contained in the following discussion and analysis.

Information pertaining to fiscal year 2017 was included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 on pages 91
through  104  under  Part  II,  Item  7,  “Management’s  Discussion  and  Analysis  of  Financial  Position  and  Results  of  Operations,”  which  was  filed  with  the
Securities and Exchange Commission (the “SEC”) on February 27, 2019.

Management Overview

Intellia Therapeutics, Inc. (“we,” “us,” “our,” “Intellia,” or the “Company”) is a leading genome editing company focused on developing curative therapeutics
utilizing  a  biological  tool  known  as  CRISPR/Cas9,  which  stands  for  Clustered,  Regularly  Interspaced  Short  Palindromic  Repeats  (“CRISPR”)/CRISPR
associated 9 (“Cas9”). This is a technology for genome editing, the process of altering selected sequences of genomic deoxyribonucleic acid (“DNA”). We
believe that CRISPR/Cas9 technology has the potential to transform medicine by editing disease-associated genes with a single treatment course, and that it
also  can  be  used  to  create  novel  engineered  cell  therapies  that  can  replace  a  patient’s  diseased  cells  or  effectively  target  various  cancers  and  autoimmune
diseases. We are leveraging our leading scientific expertise, clinical development experience and intellectual property (“IP”) position to unlock a broad set of
therapeutic applications for CRISPR/Cas9 genome editing and to develop a potential new class of therapeutic products.

Our mission is to build a company to develop curative genome editing treatments that can positively transform the lives of people living with severe and life-
threatening disease. We believe we can deliver on our mission and provide long-term benefits for all of our stakeholders by focusing on four key elements:

•

•

•

•

Develop curative CRISPR/Cas9 based medicines;

Advance our science to help more patients;

Foster an environment that is the best place to make therapies; and

Focus on long-term sustainability.

Our strategy is to build a full-spectrum genome editing company, by leveraging our CRISPR/Cas9 platform across two areas: in vivo applications, in which
CRISPR/Cas9 is the therapy, delivered to target cells within the body; and ex vivo applications, in which CRISPR/Cas9 creates the therapy of engineered
human cells. All of our revenue to date has been collaboration revenue. Since our inception and through December 31, 2019, we have raised an aggregate of
approximately $652.6 million to fund our operations, of which $154.5 million was through our collaboration agreements, $170.5 million was from our initial
public offering and concurrent private placements, $141.0 million was from a follow-on offering, $101.6 million was from at-the-market offerings and $85.0
million was from the sale of convertible preferred stock.

97

 
 
 
 
 
The breadth of our CRISPR/Cas9 platform and delivery technology allows us to pursue a multitude of therapeutic targets/clinical indications. Specifically, we
can target diseases that have the potential to be addressed by directly editing specific genes (i.e., gene knockout, repair, or insertion) as well as diseases that
may  be  targeted  by  genetically  engineered  cell  therapies.  The  successful  treatment  of  these  disorders  may  require  various  types  of  genome  edits,
CRISPR/Cas9 elements and DNA templates. We have assembled multiple in vivo and engineered cell therapy capabilities into a pipeline that reflects our full-
spectrum approach and leverages the modularity inherent in our platform.

Our diversified pipeline includes in vivo development programs targeting genetic diseases, including transthyretin amyloidosis (“ATTR”), which we are co-
developing  with  Regeneron  Pharmaceuticals,  Inc.  (“Regeneron”),  and  hereditary  angioedema  (“HAE”).  Our  pipeline  also  includes  ex  vivo  programs
consisting of two separate efforts: 1) a set of proprietary programs focused on engineered cell therapies to treat various cancers and autoimmune diseases
including  our  lead  ex  vivo  program  to  target  Wilms’  Tumor  1  (“WT1”)  for  acute  myeloid  leukemia  (“AML”);  and  2)  partnered  programs  developed  in
collaboration  with  Novartis  Institutes  for  BioMedical  Research,  Inc.  (“Novartis”),  focused  on  chimeric  antigen  receptor  (“CAR”)  T  (“CAR-T”)  cells,
hematopoietic stem cells (“HSCs”), the stem cells from which all of the various types of blood cells originate, and stem cells in the eye, or ocular stem cells
(“OSCs”).

Our Pipeline

Our diversified pipeline includes in vivo and ex vivo programs. Our in vivo programs focus on treating patients that have significant unmet medical needs due
to diseases attributable to genes expressed in the liver – ATTR (which we are co-developing with Regeneron) and HAE. Delivery plays a key role in our in
vivo  therapeutic  approach.  We  have  shown  in  animal  models  that  our  proprietary  LNP  delivery  technology,  which  encapsulates  the  therapeutic  Cas9
messenger RNA (“mRNA”) and guide RNA (“gRNA”) into lipid nanoparticles (“LNPs”), can systemically deliver these therapeutic components to the liver.

For ex vivo applications, our wholly owned programs focus on next-generation, engineered cell therapy solutions that utilize antigen specific T cell receptors
(“TCRs”). The cells to be modified ex vivo can come from the individual patient (autologous source) or from another individual (allogeneic source). Our goal
for the ex vivo pipeline is to move from autologous to allogeneic therapies, and from liquid to solid tumors.

We believe our full spectrum approach to in vivo and ex vivo programs positions us to build a pipeline across a wide range of indications.

98

 
The following table summarizes the status of our most advanced programs:

In Vivo Programs

Our selection criteria include identifying diseases that originate in the liver, have well-defined mutations that can be addressed by a single knockout, repair or
insertion approach; have readily measurable therapeutic endpoints with observable clinical responses; and for which effective treatments are absent, limited or
unduly burdensome. Our initial in vivo indications target genetic liver diseases, including ATTR and HAE. Our current efforts on in vivo delivery focus on the
use of LNPs for delivery of the CRISPR/Cas9 complex to the liver.

Transthyretin Amyloidosis – (“ATTR”)

ATTR is a progressive and fatal disorder resulting from deposition of insoluble amyloid fibrils into multiple organs and tissues leading to systemic failure.
Blood-borne transthyretin (“TTR”) protein is produced by hepatocytes and normally circulates as a soluble homotetramer that facilitates transport of vitamin
A,  via  retinol  binding  protein,  as  well  as  the  thyroid  hormone,  thyroxine.  Mutations  in  the  TTR  gene  lead  to  the  production  of  TTR  proteins  that  are
destabilized  in  their  tetramer  form.  These  tetramers  more  readily  dissociate  into  the  monomeric  form,  and  thence  to  an  aggregative  form  that  results  in
amyloid deposits in tissues. These deposits cause damage in those tissues, resulting in a disorder known as hereditary TTR amyloidosis (“hATTR”). Over 120
different genetic mutations are currently known to cause hATTR.

Deposits of TTR amyloid in the heart, nerves and/or other tissues can lead to diverse disease manifestations, including two main hereditary forms – hATTR
with polyneuropathy (“hATTR-PN”), and hATTR with cardiomyopathy (“hATTR-CM”). Typical onset of disease symptoms is during adulthood and can be
fatal within 2 to 15 years. Estimates suggest that approximately 50,000 patients suffer from hATTR worldwide.

In addition to the hereditary forms described above, ATTR can also develop spontaneously in the absence of any TTR gene mutation. This wild-type ATTR
(“wtATTR”)  is  increasingly  being  recognized  as  a  significant  and  often  undiagnosed  cause  of  heart  failure  in  the  elderly  and  is  the  subject  of  active
investigation. Recent estimates suggest that, globally, between 200,000 and 500,000 people may suffer from wtATTR with cardiomyopathy (“wtATTR-CM”).

99

 
 
 
 
In non-human primate (“NHP”) studies, we have demonstrated our ability to reduce circulating TTR protein to estimated therapeutically relevant levels after
a single systemic administration of LNPs containing our CRISPR/Cas9 complex. In December 2019, we completed a year-long durability study of our lead
LNP formulation, maintaining an average reduction of more than 95% of serum TTR protein after a single dose in NHPs. The data from our various NHP
studies has also demonstrated the transient nature of Intellia’s proprietary modular LNP delivery system, which was rapidly cleared from circulation, with all
CRISPR/Cas9 complex undetectable in blood and liver within ten days of administration.

On  August  1,  2019,  we  announced  that  we  conducted  our  pre-Investigational  New  Drug  (“IND”)  meeting  with  the  U.S.  Food  and  Drug  Administration
(“FDA”), initiated IND-enabling toxicology studies, expect to submit an IND application for NTLA-2001, our lead candidate for the treatment of ATTR, in
mid-2020 and anticipate dosing the first patients in the second half of 2020. NTLA-2001 is being co-developed with Regeneron pursuant to a license and
collaboration agreement and a Co-Development and Co-Promotion agreement directed to ATTR (the “ATTR Co/Co”) with Regeneron under which we are the
lead  development  and  commercialization  party.  Under  the  terms  of  the  ATTR  Co/Co,  Regeneron  was  reimbursing  us  for  50%  of  the  costs  and  has  been
entitled to 50% of the profits.  On December 13, 2019, Regeneron informed us that it would exercise its right under the ATTR Co/Co to modify its shares of
worldwide  development  costs  and  profits  from  50%  to  25%,  effective  six  months  after  its  notice.  Pursuant  to  the  ATTR  Co/Co,  Regeneron  funded
approximately  50%  of  the  program’s  development  costs  through  2019.  Starting  June  2020  and  thereafter,  Regeneron  will  share  approximately  25%  of
worldwide development costs and commercial profits for the ATTR program.

Hereditary Angioedema – (“HAE”)

HAE  is  a  rare  genetic  disorder  characterized  by  recurrent,  painful  and  unpredictable  episodes  of  severe  swelling.  The  most  common  areas  of  the  body  to
develop  swelling  are  the  limbs,  face,  intestinal  tract  and  airway.  Minor  trauma  or  stress  may  trigger  an  attack  but  swelling  often  occurs  without  a  known
trigger. Episodes involving the intestinal tract cause severe abdominal pain, nausea and vomiting. Swelling in the airway can restrict breathing and lead to
life-threatening obstruction of the airway. The disease is caused by increased levels of bradykinin, a protein which leads to swelling. Most patients with HAE
have a deficiency of C1 esterase inhibitor (“C1-INH”) protein, which normally prevents the unregulated release and buildup of bradykinin. HAE is estimated
to affect 1 in 50,000 people, with an estimated 11,000 to 21,500 diagnosed HAE patients in the U.S. and Europe.

Currently there are multiple therapies approved to treat HAE, including acute and prophylactic approaches. Acute treatments are used to treat patients who are
experiencing an attack. Prophylactic treatments are used to reduce the number of attacks that a patient may experience. Prophylactic treatments have proven
to be effective in reducing the number of attacks for most patients, though some patients still experience breakthrough attacks and such treatment options
require regular injections which can be associated with significant treatment burden and impact on quality of life.

Using our modular LNP delivery system, we aim to knock out the kallikrein B1 (“KLKB1”) gene with a single course of treatment to reduce the spontaneous
activation  of  biological  pathways  responsible  for  generating  bradykinin  and  thereby  ameliorate  the  frequency  and  intensity  of  HAE  attacks.  We  believe
KLKB1 knockout to be safe, as humans with prekallikrein deficiency appear to have no known health effects. In addition, inhibition of kallikrein activity has
proven to be a clinically effective approach as a prophylactic treatment for HAE.

In February 2020, we shared data demonstrating that the knockout of KLKB1 produced in NHPs resulted in a 90% reduction in kallikrein activity following a
single dose. The reduction of kallikrein activity observed corresponds to the reduced enzymatic levels in patients that meaningfully impact HAE attack rates
(Source: Banerji et al., NEJM, 2017). This kallikrein activity reduction was sustained for at least five months in an ongoing study, in a highly reproducible
manner observed across both rodent and NHP studies. We expect to nominate a development candidate for the treatment of HAE in the first half of 2020. The
KLKB1  HAE  program  is  subject  to  an  option  by  Regeneron  to  enter  into  a  Co/Co  agreement  prior  to  the  initiation  of  IND-enabling  studies,  in  which  we
would remain the lead party.

100

 
Ex Vivo Programs

We are independently researching and developing proprietary engineered cell therapies to treat various oncological and autoimmune diseases, for example
TCR-engineered  T  cells  for  immuno-oncology  applications  and  engineered  regulatory  T  cells  for  autoimmune  disorders.  Our  diverse  product  strategy
includes multiple elements. In particular:

•

•

•

We  are  exploring  non-CAR-T  cellular  approaches  that  use  immune  cells,  including  T  cells  expressing  recombinant  TCRs,  for  oncology
indications.  For  example,  in  our  existing  collaboration  with  IRCCS  Ospedale  San  Raffaele  (“OSR”),  Milan,  a  leading  European  research-
university hospital, we have identified optimized TCRs recognizing a tumor target, WT1, that could be used to treat a variety of cancers.

We seek to develop allogeneic cellular therapies, which are those derived from unmatched donors and modified outside of the human body to
allow them to be administered to an unrelated patient.

We are also exploring methods to apply CRISPR/Cas9 editing to CD4 immune cells to induce a non-reverting regulatory T cell phenotype, to
create therapies that address autoimmune diseases.

In addition, our partner Novartis is developing therapies using CAR-T cells for oncology indications, as well as HSC and OSC-based therapies.

Acute Myeloid Leukemia (“AML”)

AML includes a heterogenous group of blood cancers arising from the malignant expansion of hematopoietic cells of the myeloid lineage. AML is associated
with weakness, fatigue and bleeding resulting from the depletion of healthy myeloid cells, and is typically rapidly progressive and fatal without immediate
treatment. AML is an aggressive and hard-to-treat cancer, resulting in less than 30% of patients living more than five years after diagnosis. AML is the most
common acute leukemia in adults and is associated with the largest number of annual deaths from leukemia in the U.S. It is estimated that there have been
nearly 11,000 deaths due to AML, as well as over 21,000 new AML cases in the U.S. in 2019. While AML can occur at any age, the prevalence of the disease
increases with age, resulting in a median age at diagnosis of 67 years.

Over the past several years, new treatments have emerged for AML with different mechanisms of action. While these treatments have led to improvements in
response rates and in some cases increased overall survival, the outcomes demonstrated thus far have been incremental in nature and long-term outcomes in
AML continue to be extremely poor.

We have nominated NTLA-5001 as our first engineered T cell therapy development candidate for the treatment of AML, utilizing our TCR-directed approach
to  target  the  WT1  intracellular  antigen.  Our  WT1-directed  TCR  T-cell  therapy  aims  to  develop  a  broadly  applicable  treatment  for  AML,  regardless  of
mutational  background  of  a  patient’s  leukemia.  This  approach  employs  CRISPR/Cas9  complexes  to  knock  out  and  replace  the  endogenous  TCR  with  a
natural, high affinity therapeutic TCR. The resulting cells are engineered to be capable of specific and potent killing of AML blasts without bone marrow cell
toxicity.  In  February  2020,  we  presented  data  demonstrating  that  the  selection  of  a  natural,  high-affinity  TCR,  in  combination  with  our  CRISPR-enabled
engineering  and  targeted  insertion,  results  in  an  engineered  T  cell  capable  of  specific  and  potent  killing  of  primary  AML  blasts.  Importantly,  our  studies
showed that CRISPR-enabled engineering overcomes key challenges of traditional TCR approaches, such as mispairing between therapeutic and endogenous
TCR, therefore creating a more homogenous T cell product. The cells engineered with our lead WT1 TCR also exhibited no detectable off-target reactivity to
bone marrow cells, which express WT1 at low levels. We continue to advance good manufacturing practices (“GMP”) manufacturing-related development
activities in support of a Phase I clinical trial. We expect to submit an IND application for the use of NTLA-5001 to treat AML in the first half of 2021.

101

 
 
 
 
Research Collaboration with Novartis

Under our collaboration agreement with Novartis, we received an upfront technology access payment from Novartis of $10.0 million, and we have received
an additional $50.0 million, in aggregate, in additional technology access fees and research payments during the five-year collaboration term. In December
2019, the research term ended, although the 2014 Novartis Agreement remains in effect. Accordingly, Novartis has selected various CAR-T cell, HSC and
OSC targets for continued development, for which we will be eligible to receive milestone and royalty payments in the future. Further, we are eligible to earn
up to $230.3 million in development, regulatory and sales-based milestone payments and mid-single-digit royalties, in each case, on a per-product basis for
the  products  developed  by  Novartis,  subject  to  certain  target-based  limitations.  For  more  information  regarding  our  collaboration  with  Novartis,  see  the
section below entitled “Collaborations - Novartis.”

CAR-T Cell Program

In 2017, the first CAR-T cell products, including Novartis’ Kymriah, were approved by the FDA to treat certain oncological indications such as pediatric
acute lymphoblastic leukemia and Non-Hodgkins Lymphoma. Additional therapies are being developed for blood cancers such as AML, multiple myeloma
and chronic lymphocytic leukemia, as well as several solid-tumor cancers. In CAR-T cell therapy, naturally-occurring immune cells, specifically T cells, are
modified ex vivo by inserting a CAR into the T cells, thereby redirecting their response towards cancer cells.

CAR-T cell products can benefit from the application of CRISPR/Cas9 in multiple ways, including:

•

•

•

•

CRISPR/Cas9  could  be  used  to  create  a  universal  donor  CAR-T  cell  by  knocking  out  cell  surface  markers  that  cause  a  patient’s  immune
system  to  recognize  another  person’s  cells  as  foreign.  Allowing  multiple  patients  to  be  treated  using  cells  from  a  single  donor  could
significantly streamline manufacturing and make CAR-T cell therapy more widely accessible.

CRISPR/Cas9 could be used to modify the T cells to enhance their survival or activity against cancer cells.

CRISPR/Cas9 could be used to introduce the CAR into a precise location in the genome with a specific integrated copy number, as opposed
to the current method involving semi-random integration, thus potentially improving the safety profile of the resulting cells.

CRISPR/Cas9 could be used to knock out one or more of the proteins believed to be responsible for certain serious side effects that can result
in dangerously high fevers or severe loss of blood pressure.

Novartis  is  progressing  CRISPR/Cas9-edited  CAR-T  cells  directed  to  its  selected  CAR  targets.  The  target  selection  process  was  completed  by  the  end  of
2019, and all non-selected CAR targets are available for our development.

HSC Program

HSCs are the stem cells from which all of the various types of blood cells originate. The HSCs present in transplanted bone marrow, mobilized peripheral
blood or cord blood can repopulate a patient’s blood system. There are multiple potential opportunities for treating patients using engineered HSCs, including
treating three common classes of blood-related disorders, such as hemoglobin disorders, including sickle cell disease and beta thalassemia; primary immune
deficiencies, such as X-linked severe combined immunodeficiency; and bone marrow failures, such as Fanconi anemia. There are limited treatment options
available for these types of blood disorders, and available options typically require chronic blood transfusions or bone marrow transplants. These procedures
are  associated  with  significant  risk,  including  mortality.  We  believe  the  CRISPR/Cas9  system  can  be  used  to  potentially  provide  curative  benefits  by
correcting  the  underlying  genetic  defect  in  blood  cells  of  patients  with  these  disorders.  In  additional  applications,  normal  HSCs  may  be  engineered  ex
vivo using CRISPR/Cas9 to express a therapeutic protein, which is then administered to patients in need of that protein. In 2019, Novartis completed IND-
enabling studies in support of a potential IND on a program targeting sickle cell disease that leveraged our CRISPR/Cas 9 technology. We are entitled to
receive a $5.0 million payment related to this regulatory milestone upon filing the IND. During the research collaboration with Novartis that concluded in
December 2019, we pursued a number of potential gene targets and therapeutic indications with Novartis. From those targets, Novartis has selected a limited
number of HSC targets for development into human therapeutics. Novartis’ ability to select additional HSC therapeutic targets under the agreement expired in
December 2019.

102

 
 
 
 
 
OSC Program

In 2018 we announced an expansion of our existing cell therapy collaboration with Novartis to include the ex vivo development of innovative cell therapies
using certain OSCs. As part of the updated collaboration terms, Novartis obtained the right to develop CRISPR/Cas9-based products for a limited number of
targets using these stem cells. Novartis’ selection period for additional OSC targets expired in December 2019. We received a one-time $10.0 million cash
payment and, consistent with the original collaboration agreement, we are also eligible to receive downstream success-based milestones and royalties. We
retained rights to all other in vivo and ex vivo applications of CRISPR/Cas9, including for eye disorders.

Other Research Programs

We are pursuing a number of in vivo and ex vivo genome editing programs. Within our in vivo research efforts, we continue to work on programs such as
primary hyperoxaluria Type 1 (“PH1”), alpha-1 antitrypsin deficiency (“AATD”), and Hemophilia B, which leverage our capabilities to knockout, insert and
make consecutive edits to the genome. We are also investigating delivery strategies that target tissues outside of the liver.

Within  our  ex  vivo  research  efforts,  we  are  developing  engineered  cell  therapies  to  treat  a  range  of  hematological  and  solid  tumors.  We  are  pursuing
modalities, such as TCR, with broad potential in multiple indications. We continue to advance efforts to move from autologous to allogeneic and from liquid
to solid tumors.

Collaborations

Novartis

As described in “Collaborations - Novartis Institutes for BioMedical Research, Inc.,” in December 2014, we entered into a strategic license and collaboration
agreement with Novartis (the “2014 Novartis Agreement”), primarily focused on the research of new ex vivo CRISPR/Cas9-edited therapies using CAR-T
cells and HSCs.

In  December  2018,  we  entered  into  an  amendment  to  this  agreement  with  Novartis  (the  “Novartis  Amendment”),  which  expanded  the  scope  of  the  2014
Novartis Agreement to include the ex vivo development of CRISPR/Cas9-based cell therapies using limbal stem cells, a type of OSC, primarily against gene
targets selected by Novartis in exchange for a one-time payment of $10.0 million which we received in December 2018. In December 2019, per the terms of
the 2014 Novartis Agreement, the research term ended, although the 2014 Novartis Agreement remains in effect. As provided in the agreement, Novartis has
selected various CAR-T cell, HSC and OSC targets for continued development, for which we will be eligible to receive milestone and royalty payments in the
future.

Through  December  31,  2019,  we  had  recorded  a  total  of  $57.4  million  in  cash  and  accounts  receivable  under  the  2014  Novartis  Agreement  and  Novartis
Amendment. Through December 31, 2019, we have recognized $57.4 million of collaboration revenue, including $18.5 million and $10.3 million in the years
ended December 31, 2019 and 2018, respectively, in the consolidated statements of operations and comprehensive loss related to this agreement. As of the
periods  ended  December  31,  2019  and  2018,  we  had  accounts  receivable  of  $1.0  million  and  $6.0  million,  respectively,  related  to  this  agreement. As  of
December 31, 2019, we had no deferred revenue related to this agreement. As of December 31, 2018, we had deferred revenue of $14.5 million related to this
agreement.

Regeneron

As described in “Collaborations - Regeneron Pharmaceuticals, Inc.,” in April 2016, we entered into a license and collaboration agreement with Regeneron
(the “Regeneron Agreement”). The Regeneron Agreement has two principal components: (i) a product development component under which the parties will
research,  develop  and  commercialize  CRISPR/Cas-based  therapeutic  products  primarily  focused  on  genome  editing  in  the  liver,  and  (ii)  a  technology
collaboration  component,  pursuant  to  which  the  parties  will  engage  in  research  and  development  activities  aimed  at  discovering  and  developing  novel
technologies and improvements to CRISPR/Cas technology to enhance our genome editing platform. Under the Regeneron Agreement, we also may access
the Regeneron Genetics Center and proprietary mouse models to be provided by Regeneron for a limited number of our liver programs.

103

 
Through  December  31,  2019,  we  have  recorded  a  $75.0  million  upfront  payment  and  $24.1  million  for  research  and  development  services  under  the
Regeneron agreement. Through December 31, 2019, we have recognized $70.3 million of collaboration revenue, including $24.6 million and $20.1 million in
the  years  ended  December  31,  2019 and 2018,  respectively.  This  includes  $12.0  million  and  $7.5  million,  respectively,  representing  payments  due  from
Regeneron  pursuant  to  the  ATTR  Co/Co  agreement,  which  is  accounted  for  under  Accounting  Standards  Codification  (“ASC”)  808,  Collaborative
Arrangements (“ASC 808”). As of December 31, 2019 and 2018, we had accounts receivable of $3.6 million  and  $1.5  million,  respectively,  and  deferred
revenue of $28.8 million and $41.4 million, respectively, related to this agreement.

Collaboration Revenue

Collaboration  revenue  increased  $12.7  million  to  $43.1  million  during  the  year  ended  December  31,  2019,  as  compared  to  $30.4  million  during  the  year
ended December 31, 2018. The increase in collaboration revenue during the year ended December 31, 2019 is primarily caused by a $8.5 million increase
related  to  the  Novartis  Amendment  to  the  2014  Novartis  Agreement,  for  which  we  received  a  one-time  payment  of  $10.0  million  in  December  2018.
Additionally,  collaboration  revenue  increased  $4.5  million  in  2019  over  2018  due  to  increased  research  and  development  services  related  to  our  ATTR
program,  increasing  to  $12.0  million  during  2019  as  compared  with  $7.5  million  in  2018.  Regeneron  was  obligated  to  fund  50%  of  the  research  and
development costs for the ATTR program.

Research and Development

Research  and  development  expenses  increased  $19.3 million  to  $108.4 million  during  the  year  ended  December  31,  2019,  as  compared  to  $89.1  million
during the year ended December 31, 2018. This increase is primarily related to an increase in research and development expenses of $10.3 million related to
laboratory supplies, research materials and contract services for the further advancement of our pipeline and platform costs; an increase in personnel-related
costs of $4.7 million, driven by our growth in headcount; and an increase related to IP license and acquisition costs of $1.7 million. These increases were
offset in part by a $2.0 million decrease in stock-based compensation due primarily to some of our earlier grants being fully vested.

During  2020,  we  expect  research  and  development  expenses  to  increase  as  we  continue  to  grow  our  research  and  development  team  and  begin  clinical
development.

General and Administrative

General and administrative expenses increased $8.9 million to $41.1 million during the year ended December 31, 2019, as compared to $32.2 million during
the  year  ended  December  31,  2018.  This  increase  was  primarily  related  to  an  increase  of  $5.5  million  in  legal  fees,  which  were  principally  related  to  IP
matters, an increase of $1.7 million in personnel-related costs and $0.5 million in professional services.

Interest Income

Interest  income  increased  by  $1.3 million  to  $6.8 million  during  the  year  ended  December  31,  2019  as  compared  to  $5.5  million  during  the  year  ended
December 31, 2018. This increase was primarily caused by an increase in our average invested balance.

Liquidity and Capital Resources

Since our inception through December 31, 2019, we have raised an aggregate of $652.6 million to fund our operations, of which $154.5 million was through
our collaboration agreements, $170.5 million was from our initial public offering and concurrent private placements, $141.0 million was from a follow-on
public offering, $101.6 million was from at-the-market offerings and $85.0 million was from the sale of convertible preferred stock.

As of December 31, 2019, we had $284.5 million in cash, cash equivalents and marketable securities.

We are eligible to earn a significant amount of milestone payments and royalties, in each case, on a per-product basis under our collaboration with Novartis
and on a per-target basis under our collaboration with Regeneron, subject to the provisions of our agreements with each of them. Our ability to earn these
payments and the timing of achieving these milestones is dependent upon the outcome of our or their research and development activities and is uncertain at
this time. Our rights to payments under our collaboration agreements are our only committed external source of funds.

105

 
At-the-Market Offering Programs

On October 12, 2018, we filed a Shelf Registration Statement on Form S-3 (the “2018 Shelf”) with the SEC in relation to the registration of common stock,
preferred stock, warrants and units of any combination thereof for the purposes of selling, from time to time, our common stock, convertible securities or
other equity securities in one or more offerings. We also simultaneously entered into an Open Market Sale Agreement (the “2018 Sales Agreement”) with
Jefferies LLC (the “Sales Agent”), to provide for the offering, issuance and sale of up to an aggregate amount of $100.0 million of our common stock from
time to time in “at-the-market” offerings under the 2018 Shelf and subject to the limitations thereof. We have paid the Sales Agent cash commissions of 3.0%
of the gross proceeds of sales of common stock under the 2018 Sales Agreement. In November 2018, we issued 1,659,300 shares of our common stock at
$18.00 per share in accordance with the 2018 Sales Agreement for aggregate net proceeds of $28.5 million, after payment of cash commissions to the Sales
Agent and approximately $0.4 million related to legal, accounting and other fees in connection with the sale. During the twelve months ended December 31,
2019, we issued an additional 4,231,348 shares of our common stock, in a series of sales, at an average price of $16.57 per share, in accordance with the 2018
Sales Agreement, for aggregate net proceeds of $67.8 million, after payment of cash commissions to the Sales Agent and approximately $0.2 million related
to legal, accounting and other fees in connection with the sales. As of December 31, 2019, there were no shares of common stock eligible for sale under the
2018 Sales Agreement.

On August 23, 2019, we filed a Registration Statement on Form S-3, as amended (the “2019 Shelf”) with the SEC in relation to the registration of common
stock, preferred stock, warrants and units of any combination thereof. We also simultaneously entered into an Open Market Sale Agreement (the “2019 Sales
Agreement”) with the Sales Agent, to provide for the offering, issuance and sale by us of up to an aggregate amount of $150.0 million of our common stock
from  time  to  time  in  “at-the-market”  offerings  under  the  2019  Shelf  and  subject  to  the  limitations  thereof.  We  agreed  to  pay  to  the  Sales  Agent  cash
commissions of 3.0% of the gross proceeds of sales of common stock under the 2019 Sales Agreement. During the year ended December 31, 2019, we issued
287,231 shares of our common stock, in a series of sales, at an average price of $16.48 per share, in accordance with the 2019 Sales Agreement, for aggregate
net proceeds of $4.4 million, after payment of cash commissions to the Sales Agent and approximately $0.2 million related to legal, accounting and other fees
in connection with the sales. As of December 31, 2019, approximately $145.3 million in shares of common stock remain eligible for sale under the 2019
Sales Agreement.

Funding Requirements

Our  primary  uses  of  capital  are,  and  we  expect  will  continue  to  be,  research  and  development  contracted  services,  compensation  and  related  expenses,
laboratory  and  office  facilities,  research  supplies,  legal  and  regulatory  expenses,  patent  prosecution  filing  and  maintenance  costs  for  our  licensed  IP  and
general overhead costs. During 2020, we expect our expenses to increase compared to prior periods in connection with our ongoing activities, as we continue
to grow our research and development team and begin clinical development.

Because  our  research  programs  are  still  in  preclinical  development  and  the  outcome  of  these  efforts  is  uncertain,  we  cannot  estimate  the  actual  amounts
necessary  to  successfully  complete  the  development  and  commercialization  of  any  future  product  candidates  or  whether,  or  when,  we  may  achieve
profitability. Until such time as we can generate substantial product revenues, if ever, we expect to finance our ongoing cash needs through equity financings
and  collaboration  arrangements.  We  receive  cost  reimbursements  from  Regeneron  for  the  ATTR  program.  Additionally,  we  are  eligible  to  earn  milestone
payments  and  royalties,  in  each  case,  on  a  per-product  basis  under  our  collaboration  with  Novartis  and  on  a  per-target  basis  under  our  collaboration  with
Regeneron, subject to the provisions of our agreements with each of them. Except for these sources of funding, we will not have any committed external
source of liquidity. To the extent that we raise additional capital through the future sale of equity, the ownership interest of our stockholders will be diluted,
and  the  terms  of  these  securities  may  include  liquidation  or  other  preferences  that  adversely  affect  the  rights  of  our  existing  stockholders.  If  we  raise
additional funds through collaboration arrangements in the future, we may have to relinquish valuable rights to our technologies, future revenue streams or
product  candidates  or  grant  licenses  on  terms  that  may  not  be  favorable  to  us.  If  we  are  unable  to  raise  additional  funds  through  equity  financings  when
needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and
market product candidates that we would otherwise prefer to develop and market ourselves.

106

 
Outlook

Based on our research and development plans and our expectations related to the progress of our programs, we expect that our cash, cash equivalents and
marketable securities as  of  December  31,  2019,  as  well  as  research  and  cost  reimbursement  funding  from  Regeneron,  will  enable  us  to  fund  our  ongoing
operating expenses and capital expenditure requirements at least to the end of 2021, excluding any potential milestone payments or extension fees that could
be  earned  and  distributed  under  the  collaboration  agreements  with  Regeneron  and  Novartis  or  any  strategic  use  of  capital  not  currently  in  the  base  case
planning assumptions. We have based this estimate on current assumptions that may prove to be wrong, and we could use our capital resources sooner than
we expect.

Our ability to generate revenue and achieve profitability depends significantly on our success in many areas, including: developing our delivery technologies
and  our  CRISPR/Cas9  technology  platform;  selecting  appropriate  product  candidates  to  develop;  completing  research  and  preclinical  and  clinical
development  of  selected  product  candidates;  obtaining  regulatory  approvals  and  marketing  authorizations  for  product  candidates  for  which  we  complete
clinical  trials;  developing  a  sustainable  and  scalable  manufacturing  process  for  product  candidates;  launching  and  commercializing  product  candidates  for
which we obtain regulatory approvals and marketing authorizations, either directly or with a collaborator or distributor; obtaining market acceptance of our
product candidates; addressing any competing technological and market developments; negotiating favorable terms in any collaboration, licensing, or other
arrangements  into  which  we  may  enter;  maintaining  good  relationships  with  our  collaborators  and  licensors;  maintaining,  protecting,  and  expanding  our
portfolio of IP rights, including patents, trade secrets, and know-how; and attracting, hiring, and retaining qualified personnel.

Net cash used in operating activities of $103.2 million and $61.3 million during the years ended December 31, 2019 and 2018, respectively, primarily reflect
increased spend in our research and development and general and administrative activities, offset in part by the receipt of $18.9 million and $29.4 million in
payments from our collaboration partners, respectively, during those periods.

Net cash provided by (used in) investing activities

During  the  year  ended  December  31,  2019,  our  investing  activities  provided  net  cash  of  $25.2  million.  During  the  year  ended  December  31,  2018,  our
investing activities used net cash of $260.8 million. The increase in the year ended December 31, 2019 is primarily due to an increase of $32.0 million from
marketable  securities  activity  during  the  period,  as  $329.0  million  in  marketable  securities  matured  and  $297.0  million  in  marketable  securities  were
purchased. This increase was offset in part by the use of $6.8 million related to purchases of property and equipment as we continue to grow our operations.
The  decrease  in  the  year  ended  December  31,  2018  was  primarily  for  the  purchase  of  marketable  securities  amounting  to  $254.6  million  as  a  result  of  a
change to our investment policy in September 2018, allowing for investment in marketable securities. This change in policy resulted in $255.2 million being
shown  as  marketable  securities  on  our  December  31,  2018  balance  sheet.  The  remainder  of  the  decrease  in  the  year  ended  December  31,  2018  related  to
purchases of property and equipment as we grew our operations and build out of our office and laboratory facilities after moving to our new corporate office
in December 2016.

market offerings, $3.1 million in cash received from the exercise of stock options and $1.1 million in cash received from the issuance of shares through our
employee stock purchase plan. Net cash provided by financing activities of $40.2 million during the year ended December 31, 2018 includes $28.5 million in
net proceeds from an at-the-market offering, $10.7 million in cash received from the exercise of stock options and $1.0 million in cash received from the
issuance of shares through our employee stock purchase plan.

The amounts reported for property leases represent future minimum lease payments under non-cancelable operating leases in effect as of December 31, 2019.
The minimum lease payments do not include common area maintenance charges or real estate taxes.

Other arrangements represent agreements with certain vendors for supply manufacturing, preclinical research studies and other services and products that are
enforceable and legally binding.

Other contractual obligations

The contractual obligations table does not include any potential future pass-through milestone payments or royalty payments we may be required to make
under  our  existing  license  agreements  due  to  the  uncertainty  of  the  occurrence  of  the  events  requiring  payment  under  those  agreements.  The  table  also
excludes our obligation to pay 30.0% of Caribou’s patent prosecution filing and maintenance costs for licensed IP as such costs cannot be reliably estimated
until incurred.

Critical Accounting Policies and Use of Estimates

Our management’s discussion and analysis of financial condition and results of operations is based upon our consolidated financial statements, which have
been prepared in accordance with accounting principles generally accepted in the U.S. The preparation of these consolidated financial statements requires us
to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of
the  date  of  the  balance  sheets  and  the  reported  amounts  of  collaboration  revenue  and  expenses  during  the  reporting  periods.  We  base  our  estimates  on
historical experience and on various other assumptions that we believe to be reasonable under the circumstances at the time such estimates are made. Actual
results  and  outcomes  may  differ  materially  from  our  estimates,  judgments  and  assumptions.  We  periodically  review  our  estimates  in  light  of  changes  in
circumstances, facts and experience. The effects of material revisions in estimates are reflected in the consolidated financial statements prospectively from the
date of the change in estimate.

We  define  our  critical  accounting  policies  as  those  accounting  principles  generally  accepted  in  the  U.S.  that  require  the  most  significant  estimates  and
judgments about matters that are uncertain and are likely to have a material impact on our financial condition and results of operations as well as the specific
manner in which we apply those principles. We believe the critical accounting policies used in the preparation of our consolidated financial statements which
require significant estimates and judgments are as follows:

Revenue Recognition

We adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606), and its related amendments (collectively
known as “ASC 606”) on January 1, 2018 using the modified retrospective method. The reported results for 2019 and 2018 reflect the application of ASC 606
guidance,  while  the  reported  results  for  2017  were  prepared  under  the  guidance  of  ASC  605,  Revenue Recognition  (“ASC  605”  or  “legacy  GAAP”).  The
adoption of ASC 606 represented a change in accounting principle that more closely aligns revenue recognition with the delivery of our goods and services
and provides financial statement readers with enhanced disclosures.

At inception, we determine whether contracts are within the scope of ASC 606 or other topics. For contracts that are determined to be within the scope of
ASC 606, revenue is recognized when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the consideration
to which we expect to be entitled to receive in exchange for these goods and services. To achieve this core principle, we apply the following five steps (i)
identify  the  contract  with  the  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 we satisfy a performance obligation. We only apply the
five-step model to contracts when we determine that collection of substantially all consideration for goods and services that are transferred is probable based
on the customer’s intent and ability to pay the promised consideration.

Performance obligations promised in a contract are identified based on the goods and services that will be transferred to the customer that are both capable of
being distinct and are distinct in the context of the contract. To the extent a contract includes multiple promised goods and services, we apply judgment to
determine whether promised goods and services are both capable of being distinct and distinct in the context of the contract. If these criteria are not met, the
promised goods and services are accounted for as a combined performance obligation.

The transaction price is determined based on the consideration to which we will be entitled in exchange for transferring goods and services to the customer.
To the extent the transaction price includes variable consideration, we estimate the amount of variable consideration that should be included in the transaction
price  utilizing  either  the  expected  value  method  or  the  most  likely  amount  method,  depending  on  the  nature  of  the  variable  consideration.  Variable
consideration is included in the transaction price if, in our judgment, it is probable that a significant future reversal of cumulative revenue under the contract
will  not  occur.  Any  estimates,  including  the  effect  of  the  constraint  on  variable  consideration,  are  evaluated  at  each  reporting  period  for  any  changes.
Determining the transaction price requires significant judgment, which is discussed in further detail for each of our collaboration agreements in Note 9. In
addition, none of our contracts as of December 31, 2019 contained a significant financing component.

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain
multiple  performance  obligations  require  an  allocation  of  the  transaction  price  to  each  performance  obligation  on  a  relative  standalone  selling  price  basis
unless the transaction price is variable and meets the criteria to be allocated entirely to a performance obligation or to a distinct service that forms part of a
single performance obligation. The consideration to be received is allocated among the separate performance obligations based on relative standalone selling
prices. We typically determine standalone selling prices using an adjusted market assessment approach model.

We satisfy performance obligations either over time or at a point in time. Revenue is recognized over time if either (i) the customer simultaneously receives
and consumes the benefits provided by the entity’s performance, (ii) the entity’s performance creates or enhances an asset that the customer controls as the
asset is created or enhanced, or (iii) the entity’s performance does not create an asset with an alternative use to the entity and the entity has an enforceable
right to payment for performance completed to date. If the entity does not satisfy a performance obligation over time, the related performance obligation is
satisfied at a point in time by transferring the control of a promised good or service to a customer. We evaluate the measure of progress each reporting period
and, if necessary, adjust the measure of performance and related revenue recognition.

109

 
 
 
 
 
 
 
 
As of December 31, 2019, our only revenue recognized is related to collaboration agreements with third parties which are either within the scope of ASC 606,
under which we license certain rights to our product candidates to third parties, or within the scope of ASC 808, Collaborative Arrangements (“ASC 808”) if
it  involves  a  joint  operating  activity  pursuant  to  which  we are  an  active  participant  and  are  exposed  to  significant  risks  and  rewards  with  respect  to  the
arrangement. As discussed in further detail in Note 9, we enter into out-licensing agreements which are within the scope of ASC 606, under which we license
certain rights to our product candidates to third parties. The terms of these arrangements typically include payment to us of one or more of the following:
nonrefundable, upfront fees; development, regulatory, and commercial milestone payments; research and development funding payments; and royalties on the
net  sales  of  licensed  products.  Each  of  these  payments  results  in  collaboration  revenues,  except  for  revenues  from  royalties  on  the  net  sales  of  licensed
products,  which  are  classified  as  royalty  revenues.  For  arrangements  within  the  scope  of  ASC  808,  the  terms  of  these  arrangements  typically  include
payments received or made under the cost sharing provisions which are recognized as a component of revenues in the consolidated statements of operations
and comprehensive loss.

Licenses of intellectual property: If the license to our IP is determined to be distinct from the other performance obligations identified in the arrangement, we
recognize revenues from consideration allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from
the licenses. For licenses that are combined with other promises, we utilize judgment to determine whether the combined performance obligation is satisfied
over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue.

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

Royalties:  For  arrangements  that  include  sales-based  royalties,  including  milestone  payments  based  on  levels  of  sales,  if  the  license  is  deemed  to  be  the
predominant item to which the royalties relate, we recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to
which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, we have not recognized any royalty revenue resulting
from any of our collaboration agreements.

We receive payments from our customers based on billing schedules established in each contract. Our contract liabilities consist of deferred revenue. Upfront
payments and fees are recorded as deferred revenue upon receipt or when due and may require deferral of revenue recognition to a future period until we
satisfy our obligations under these arrangements.

We also consider the nature and contractual terms of an arrangement and assess whether the arrangement involves a joint operating activity pursuant to which
we are an active participant and exposed to significant risks and rewards with respect to the arrangement. If we are an active participant and exposed to the
significant risks and rewards with respect to the arrangement, we account for the arrangement under ASC 808. Based on this consideration, we account for
our  Co/Co  agreement  with  Regeneron  under  ASC  808.  Because  ASC  808  does  not  provide  recognition  and  measurement  guidance  for  collaborative
arrangements, we have analogized to ASC 606.

Costs to obtain and fulfill a contract

We did not incur any expenses to obtain collaboration agreements and costs to fulfill those contracts do not generate or enhance our resources. As such, no
costs to obtain or fulfill a contract have been capitalized in any period.

Equity-Based Compensation

We  measure  employee  equity-based  compensation  based  on  the  grant  date  fair  value  of  the  equity  awards  using  the  Black-Scholes  option  pricing  model.
Equity-based  compensation  expense  is  recognized  on  a  straight-line  basis  over  the  requisite  service  period  of  the  awards  and  is  adjusted  for  pre-vesting
forfeitures in the period in which the forfeitures occur. For equity awards that have a performance condition, we recognize compensation expense based on
our assessment of the probability that the performance condition will be achieved.

We classify equity-based compensation expense in our consolidated statement of operations and comprehensive loss in the same manner in which the award
recipient’s salary and related costs are classified or in which the award recipient’s service payments are classified.

Recent Accounting Pronouncements

Please read Note 2 to our consolidated financial statements included in Part IV, Item 15, “Notes to Consolidated Financial Statements,” of this annual report
on Form 10-K for a description of recent accounting pronouncements applicable to our business.

Off-Balance Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements as defined under the rules and regulations of
the SEC.

Item 7A.

Quantitative and Qualitative Disclosures about Market Risk

The market risk inherent in our financial instruments and in our financial position represents the potential loss arising from adverse changes in interest rates.
As  of  December  31,  2019,  we  had  cash  equivalents  and  marketable  securities  of  $274.2  million  consisting  of  interest-bearing  money  market  accounts,
commercial paper, corporate and financial institution debt securities, U.S. Treasury securities and asset-backed securities. Our primary exposure to market
risk is interest rate sensitivity, which is affected by changes in the general level of U.S. interest rates, particularly because our investments are primarily in
marketable securities. Due to the short-term duration of our investment portfolios and the low risk profile of our investments, we do not believe an immediate
change of 100 basis points, or one percentage point, would have a material effect on the fair market value of our investment portfolio. Declines in interest
rates, however, would reduce future investment income.

We do not have any foreign currency or derivative financial instruments. Inflation generally affects us by increasing our cost of labor and clinical trial costs.
We do not believe that inflation had a material effect on our results of operations during the year ended December 31, 2019.

Our management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness
of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this
Annual Report on Form 10-K. Management recognizes that any disclosure controls and procedures, no matter how well designed and operated, can provide
only  reasonable  assurance  of  achieving  their  objectives.  Our  disclosure  controls  and  procedures  have  been  designed  to  provide  reasonable  assurance  of
achieving  their  objectives.  Based  on  such  evaluation,  our  Chief  Executive  Officer  and  Chief  Financial  Officer  concluded  that  our  disclosure  controls  and
procedures were effective at the reasonable assurance level as of December 31, 2019.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is
defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, the company’s principal
executive and principal financial officers and effected by the company’s board of directors, management and other personnel, to provide reasonable assurance
regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in  accordance  with  generally  accepted
accounting principles and includes those policies and procedures that:

•

•

•

Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of
the company;

Provide  reasonable  assurance  that  transactions  are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in  accordance  with
generally  accepted  accounting  principles,  and  that  receipts  and  expenditures  of  the  company  are  being  made  only  in  accordance  with
authorizations of management and directors of the company; and

Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets
that could have a material effect on the financial statements.

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements.  Therefore,  even  those  systems
determined  to  be  effective  can  provide  only  reasonable  assurance  with  respect  to  financial  statement  preparation  and  presentation.  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.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2019. In making this assessment, management
used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework (2013
framework) (“COSO”). Based on its assessment, management believes that, as of December 31, 2019, our internal control over financial reporting is effective
based on those criteria.

Deloitte & Touche LLP, our independent registered public accounting firm, has issued an attestation report on the effectiveness of our internal control over
financial reporting, which is included below.

Changes in Internal Controls over Financial Reporting

No change in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during
the  three  months  ended  December  31,  2019  that  has  materially  affected,  or  is  reasonably  likely  to  materially  affect,  the  Company’s  internal  control  over
financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the stockholders and the Board of Directors of Intellia Therapeutics, Inc.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Intellia Therapeutics, Inc. and subsidiary (the “Company”) as of December 31, 2019, based on
criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission
(COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, based
on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated
financial statements as of and for the year ended December 31, 2019, of the Company and our report dated February 27, 2020, expressed an unqualified
opinion on those financial statements and included an explanatory paragraph regarding the Company’s adoption of Accounting Standards Codification Topic
842, Leases, on January 1, 2019.
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 Annual 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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the stockholders and the Board of Directors of Intellia Therapeutics, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Intellia Therapeutics, Inc. and subsidiary (the "Company") as of December 31, 2019 and
2018, the related consolidated statements of operations and comprehensive loss, stockholders’ equity, and cash flows, for each of the three years in the period
ended December 31, 2019, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly,
in all material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each
of the three years in the period ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.

We  have  also  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, 2019, based on criteria established in Internal Control — Integrated Framework (2013) issued by
the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 27, 2020, expressed an unqualified opinion on the
Company's internal control over financial reporting.

Change in Accounting Principle

As discussed in Note 2 to the financial statements, effective January 1, 2019, the Company adopted FASB Accounting Standards Codification Topic 842,
Leases, using the modified retrospective approach and utilizing the effective date as its date of adoption.

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.

Critical Audit MatterThe  critical  audit  matter  communicated  below  is  a  matter  arising  from  the  current-period  audit  of  the  financial  statements  that  was
communicated  or  required  to  be  communicated  to  the  audit  committee  and  that  (1)  relates  to  accounts  or  disclosures  that  are  material  to  the  financial
statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any
way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion
on the critical audit matter or on the accounts or disclosures to which it relates.

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required

Revenue Recognition — Collaboration Arrangements – Refer to Notes 2 and 9 to the financial statements.

Critical Audit Matter Description

F-2

 
The Company recognizes collaboration revenue on license and collaboration agreements as they fulfill their performance obligations and transfer control of
goods and services to the customer. Management uses judgement in determining when the performance obligation is complete, either over time or at a point
in time. For performance obligations related to services that are required to be recognized over time, there is significant judgment involved in determining the
most  appropriate  measure  of  progress  towards  satisfaction  of  each  performance  obligation.  As  of  December  31,  2019,  collaboration  revenue  was  $43.1
million, of which $31.1 million was recognized over time.

We  identified  revenue  recognized  over  time  as  a  critical  audit  matter  because  of  the  judgments  necessary  for  management  to  determine  an  appropriate
measure  of  progress.  This  required  an  increased  extent  of  audit  effort  and  a  high  degree  of  auditor  judgment  when  performing  procedures  to  audit  the
estimated measure of progress when revenue is recognized over time.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the estimated measure of progress included the following, among others:

•

•

We tested the effectiveness of controls over the Company’s revenue recognition process, including controls over management’s estimated
measure of progress when revenue is recognized over time.  

We selected collaboration agreements and performed the following:

o

o

Evaluated the appropriateness and consistency of the methods and assumptions used by management to develop the estimated
measure of progress and performed corroborating inquiries with the Company’s project managers and scientists.

Tested the mathematical accuracy of management’s calculation of revenue recognized over time.

INTELLIA THERAPEUTICS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.

The Company

Intellia  Therapeutics,  Inc.  (“Intellia”  or  the  “Company”)  is  a  leading  genome  editing  company  focused  on  developing  curative  therapeutics  utilizing  a
biological  tool  known  as  CRISPR/Cas9,  which  stands  for  Clustered, Regularly Interspaced  Short  Palindromic  Repeats  (“CRISPR”)/CRISPR  associated  9
(“Cas9”). This is  a  technology  for  genome  editing,  the  process  of  altering  selected  sequences  of  genomic  deoxyribonucleic  acid  (“DNA”).  The  Company
believes that CRISPR/Cas9 technology has the potential to transform medicine by editing disease-associated genes with a single treatment course, and that it
can  also  be  used  to  create  novel  engineered  cell  therapies  that  can  replace  a  patient’s  diseased  cells  or  effectively  target  various  cancers  and  autoimmune
diseases.  The  Company  is  leveraging  its  leading  scientific  expertise,  clinical  development  experience  and  intellectual  property  (“IP”)  position  to  unlock  a
broad set of therapeutic applications for CRISPR/Cas9 genome editing and to develop a potential new class of therapeutic products.

The Company was founded and commenced active operations in mid-2014. The Company will require substantial additional capital to fund its research and
development. The Company is subject to risks and uncertainties common to early stage companies in the biotechnology industry, including, but not limited to,
development by competitors of more advanced or effective therapies, dependence on key executives, protection of and dependence on proprietary technology,
compliance with government regulations and ability to secure additional capital to fund operations. Programs currently moving into development will require
significant additional research and development efforts, including preclinical and clinical testing and regulatory approval prior to commercialization. These
efforts require significant amounts of additional capital, adequate personnel and infrastructure and extensive compliance-reporting capabilities. Even if the
Company’s product development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from product sales.

Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements include the accounts of Intellia Therapeutics, Inc. and its wholly owned, controlled subsidiary, Intellia Securities Corp.
All intercompany balances and transactions have been eliminated in consolidation. Comprehensive loss is comprised of net loss and gain/loss on marketable
securities.

Use of Estimates

The preparation of the Company’s consolidated financial statements in accordance with accounting principles generally accepted (“GAAP”) in the United
States of America (“U.S.”) requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the
disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of collaboration revenue and
expenses during the reporting periods. Significant estimates in these consolidated financial statements have been made in connection with the calculation of
revenues, research and development expenses and equity-based compensation expense. The Company bases its estimates on historical experience and various
other assumptions that management believes to be reasonable. Actual results could differ from those estimates. Changes in estimates are reflected in reported
results in the period in which they become known.

Fair Value Measurements

The  Company’s  financial  instruments  include  cash  equivalents,  marketable  securities,  accounts  receivable,  accounts  payable  and  accrued  expenses.  The
Company’s financial assets, which include cash equivalents and marketable securities, have been initially valued at the transaction price, and subsequently
revalued  at  the  end  of  each  reporting  period,  utilizing  third-party  pricing  services  or  other  observable  market  data.  The  pricing  services  utilize  industry
standard valuation models and observable market inputs to determine value.

Refer to Note 4 for further information regarding the Company’s fair value measurements.

F-8

 
 
Other financial instruments, including accounts receivable, accounts payable and accrued expenses, are carried at cost, which approximate fair value due to
the short duration and term to maturity.

Cash Equivalents

The Company considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents. As of December 31,
2019 and 2018, cash equivalents consisted of interest-bearing money market accounts.

Marketable Securities

The Company’s marketable securities are accounted for as available-for-sale and recorded at fair value with the related unrealized gains and losses included in
accumulated  other  comprehensive  income  (loss),  a  component  of  stockholders’  equity.  Refer  to  Note  3  for  further  information  regarding  the  Company’s
marketable securities.

Concentrations of Credit Risk

The  Company’s  cash,  cash  equivalents  and  marketable  securities  may  potentially  be  subject  to  concentrations  of  credit  risk.  The  Company  generally
maintains balances in various accounts in excess of federally insured limits with financial institutions that management believes to be of high credit quality.

Accounts receivable represent amounts due from collaboration partners. The Company monitors economic conditions to identify facts or circumstances that
may  indicate  that  any  of  its  accounts  receivable  are  at  risk  of  collection.  As  of  December  31,  2019  and  2018,  the  Company’s  two  collaboration  partners,
Regeneron  Pharmaceuticals,  Inc.  (“Regeneron”)  and  Novartis  Institutes  for  BioMedical  Research,  Inc.  (“Novartis”),  accounted  for  all  of  the  Company’s
accounts receivable.

Property and Equipment

The  Company  records  property  and  equipment  at  cost  and  recognizes  depreciation  and  amortization  using  the  straight-line  method  over  the  following
estimated useful lives of the respective assets:

Asset Category
Laboratory equipment
Office furniture and equipment
Computer software
Computer equipment

Leasehold improvements

Useful Life
5 years
5 years
3 years
3 years
5 years or term of respective
lease, if shorter

Expenditures  for  repairs  and  maintenance  of  assets  are  expensed  as  incurred.  Upon  retirement  or  sale,  the  cost  of  assets  disposed  and  the  corresponding
accumulated depreciation are removed from the related accounts and any resulting gain or loss is reflected in the results of operations.

Impairment of Long-Lived Assets

The Company tests long-lived assets to be held and used, including property and equipment, for impairment whenever events or changes in circumstances
indicate that the carrying amount of assets or asset groups may not be fully recoverable. Factors that the Company considers in deciding when to perform an
impairment  review  include  significant  underperformance  of  the  business  in  relation  to  expectations,  significant  negative  industry  or  economic  trends  and
significant changes or planned changes in the use of the assets.

F-9

 
 
 
 
 
 
 
 
 
 
Evaluation of recoverability of the asset or asset group is based on an estimate of undiscounted future cash flows resulting from the use of the asset or asset
group and its eventual disposition. In the event that such cash flows are not expected to be sufficient to recover the carrying amount of the asset or asset
group, the assets are written down to their estimated fair values. The impairment loss would be based on the excess of the carrying value of the impaired asset
over its fair value, determined based on discounted cash flows. To date, the Company has not recorded any material impairment losses on long-lived assets.

Income Taxes

The  Company  accounts  for  income  taxes  using  the  asset  and  liability  method,  which  requires  the  recognition  of  deferred  tax  assets  and  liabilities  for  the
expected  future  tax  consequences  attributable  to  differences  between  carrying  amounts  of  assets  and  liabilities  for  financial  reporting  purposes  and  the
amounts used for income tax reporting purposes and for operating loss and tax credit carryforwards. Changes in deferred tax assets and liabilities are recorded
in the provision for income taxes.

The Company’s deferred tax assets and liabilities are measured using enacted tax rates expected to apply in the years in which these temporary differences are
expected to be recovered or settled. A valuation allowance is recorded to reduce deferred tax assets if it is determined that it is more likely than not that all or
a portion of the deferred tax asset will not be realized. The Company considers many factors when assessing the likelihood of future realization of deferred
tax assets, including recent earnings results, expectations of future taxable income, carryforward periods available and other relevant factors. The Company
records changes in the required valuation allowance in the period that the determination is made.

The Company assesses its income tax positions and records tax benefits for all years subject to examination based upon management’s evaluation of the facts,
circumstances and information available as of the reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained,
the Company records the largest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority
having full knowledge of all relevant information. For those income tax positions where it is not more likely than not that a tax benefit will be sustained, the
Company  does  not  recognize  a  tax  benefit  in  the  financial  statements.  The  Company  records  interest  and  penalties  related  to  uncertain  tax  positions,  if
applicable, as a component of income tax expense.

Revenue Recognition

The  Company  adopted  Accounting  Standards  Update  (“ASU”)  2014-09,  Revenue  from  Contracts  with  Customers  (Topic  606)  and  its  related  amendments
(collectively  known  as  Accounting  Standard  Codification  (“ASC”)  606  “ASC  606”)  on  January  1,  2018  using  the  modified  retrospective  method.  The
reported results for 2019 and 2018 reflect the application of ASC 606 guidance while the reported results for 2017 were prepared under the guidance of ASC
605, Revenue Recognition (“ASC 605” or “legacy GAAP”). The adoption of ASC 606 represented a change in accounting principle that more closely aligns
revenue recognition with the delivery of the Company’s goods and services and provides financial statement readers with enhanced disclosures.

At inception, the Company determines whether contracts are within the scope of ASC 606 or other topics. For contracts that are determined to be within the
scope of ASC 606, revenue is recognized when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the
consideration to which the Company expects to be entitled to receive in exchange for these goods and services. To achieve this core principle, the Company
applies  the  following  five  steps  (i)  identify  the  contract  with  the  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 Company satisfies
a  performance  obligation.  The  Company  only  applies  the  five-step  model  to  contracts  when  the  Company  determines  that  collection  of  substantially  all
consideration for goods and services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration.

F-10

 
 
 
 
Performance obligations promised in a contract are identified based on the goods and services that will be transferred to the customer that are both capable of
being distinct and are distinct in the context of the contract. To the extent a contract includes multiple promised goods and services, the Company applies
judgment to determine whether promised goods and services are both capable of being distinct and distinct in the context of the contract. If these criteria are
not met, the promised goods and services are accounted for as a combined performance obligation.

The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring goods and services to the
customer.  To  the  extent  the  transaction  price  includes  variable  consideration,  the  Company  estimates  the  amount  of  variable  consideration  that  should  be
included  in  the  transaction  price  utilizing  either  the  expected  value  method  or  the  most  likely  amount  method,  depending  on  the  nature  of  the  variable
consideration.  Variable  consideration  is  included  in  the  transaction  price  if,  in  the  Company’s  judgment,  it  is  probable  that  a  significant  future  reversal  of
cumulative revenue under the contract will not occur. Any estimates, including the effect of the constraint on variable consideration, are evaluated at each
reporting  period  for  any  changes.  Determining  the  transaction  price  requires  significant  judgment,  which  is  discussed  in  further  detail  for  each  of  the
Company’s  collaboration  agreements  in  Note  9.  In  addition,  none  of  the  Company’s  contracts  as  of  December  31,  2019  contained  a  significant  financing
component.

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain
multiple  performance  obligations  require  an  allocation  of  the  transaction  price  to  each  performance  obligation  on  a  relative  standalone  selling  price  basis
unless the transaction price is variable and meets the criteria to be allocated entirely to a performance obligation or to a distinct service that forms part of a
single performance obligation. The consideration to be received is allocated among the separate performance obligations based on relative standalone selling
prices. The Company typically determines standalone selling prices using an adjusted market assessment approach model.

The  Company  satisfies  performance  obligations  either  over  time  or  at  a  point  in  time.  Revenue  is  recognized  over  time  if  either  (i)  the  customer
simultaneously receives and consumes the benefits provided by the entity’s performance, (ii) the entity’s performance creates or enhances an asset that the
customer controls as the asset is created or enhanced, or (iii) the entity’s performance does not create an asset with an alternative use to the entity and the
entity has an enforceable right to payment for performance completed to date. If the entity does not satisfy a performance obligation over time, the related
performance obligation is satisfied at a point in time by transferring the control of a promised good or service to a customer. The Company evaluates the
measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

As of December 31, 2019, the Company’s only revenue recognized is related to collaboration agreements with third parties which are either within the scope
of  ASC  606,  under  which  the  Company  licenses  certain  rights  to  its  product  candidates  to  third  parties,  or  within  the  scope  of  ASC  808,  Collaborative
Arrangements (“ASC 808”) if it involves a joint operating activity pursuant to which the Company is an active participant and is exposed to significant risks
and rewards with respect to the arrangement. For the collaboration arrangements under the scope of ASC 606, as discussed in further detail in Note 9, the
terms  of  these  arrangements  typically  include  payment  to  the  Company  of  one  or  more  of  the  following:  nonrefundable,  upfront  fees;  development,
regulatory, and commercial milestone payments; research and development funding payments; and royalties on the net sales of licensed products. Each of
these  payments  results  in  collaboration  revenues,  except  for  revenues  from  royalties  on  the  net  sales  of  licensed  products,  which  are  classified  as  royalty
revenues. For arrangements within the scope of ASC 808, the terms of these arrangements typically include payments received or made under the cost sharing
provisions which are recognized as a component of revenues in the consolidated statements of operations and comprehensive loss.

Licenses of intellectual property:  If  the  license  to  the  Company’s  IP  is  determined  to  be  distinct  from  the  other  performance  obligations  identified  in  the
arrangement, the Company recognizes revenues from consideration allocated to the license when the license is transferred to the customer and the customer is
able  to  use  and  benefit  from  the  licenses.  For  licenses  that  are  combined  with  other  promises,  the  Company  utilizes  judgment  to  assess  the  nature  of  the
combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the
appropriate method of measuring progress for purposes of recognizing revenue.

F-11

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

Royalties:  For  arrangements  that  include  sales-based  royalties,  including  milestone  payments  based  on  levels  of  sales,  if  the  license  is  deemed  to  be  the
predominant item to which the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance
obligation  to  which  some  or  all  of  the  royalty  has  been  allocated  has  been  satisfied  (or  partially  satisfied).  To  date,  the  Company  has  not  recognized  any
royalty revenue resulting from any of its collaboration agreements.

The Company receives payments from its customers based on billing schedules established in each contract. The Company’s contract liabilities consist of
deferred revenue. Upfront payments and fees are recorded as deferred revenue upon receipt or when due and may require deferral of revenue recognition to a
future period until the Company satisfies its obligations under these arrangements.

The Company also considers the nature and contractual terms of an arrangement and assesses whether the arrangement involves a joint operating activity
pursuant to which the Company is an active participant and is exposed to significant risks and rewards with respect to the arrangement. If the Company is an
active participant and is exposed to the significant risks and rewards with respect to the arrangement, the Company accounts for the arrangement under ASC
808. Based on this consideration, the Company accounts for its Co-Development and Co-Promotion (“Co/Co”) Agreement with Regeneron under ASC 808.
Because ASC 808 does not provide recognition and measurement guidance for collaborative arrangements, the Company has analogized to ASC 606. Refer to
Note 9 for additional information regarding the Company’s collaboration agreements.

Research and Development Expenses

Research and development costs are expensed as incurred. Research and development expenses consist of salaries, equity-based compensation and benefits of
employees,  lab  supplies  and  materials,  facilities  expenses,  overhead  expenses,  fees  paid  to  subcontractors  and  contract  research  organizations  and  other
external expenses.

The  Company  records  payments  made  for  research  and  development  services  prior  to  the  services  being  rendered  as  prepaid  expense  on  the  consolidated
balance sheet and expenses them as the services are provided. Contracts for multi-year research and development services are recorded on a straight-line basis
over each annual contractual period based on the total contractual fee when the services rendered are expected to be substantially equivalent over the term of
the arrangement. The cost of obtaining licenses for certain technology or IP is recorded to research and development expense when incurred if the licensed
technology or IP has not yet reached technological feasibility and has no alternative future use.

Equity-Based Compensation

The Company measures employee equity-based compensation based on the grant date fair value of the equity awards using the Black-Scholes option pricing
model.  Equity-based  compensation  expense  is  recognized  on  a  straight-line  basis  over  the  requisite  service  period  of  the  awards  and  is  adjusted  for  pre-
vesting forfeitures in the period in which the forfeitures occur. For equity awards that have a performance condition, the Company recognizes compensation
expense based on its assessment of the probability that the performance condition will be achieved.

F-12

 
 
 
 
 
The Company classifies equity-based compensation expense in its consolidated statement of operations and comprehensive loss in the same manner in which
the award recipient’s salary and related costs are classified or in which the award recipient’s service payments are classified.

(Loss) Earnings per Share

The  Company  calculates  basic  (loss)  earnings  per  share  by  dividing  (loss)  income  by  the  weighted  average  number  of  common  shares  outstanding.  The
Company computes diluted (loss) earnings per share after giving consideration to the dilutive effect of stock options and unvested restricted stock that are
outstanding during the period, except where such non-participating securities would be anti-dilutive.

Segment Information

The Company manages its operations as a single segment for the purposes of assessing performance and making operating decisions. The Company’s one
business segment is the development of genome editing-based therapies. All of the Company’s assets are held in the U.S. and all of the Company’s revenue
has been generated in the U.S.

Recent Accounting Pronouncements – Adopted

Leases

Effective  January  1,  2019,  the  Company  adopted  ASC  842,  Leases  (“ASC  842”),  using  the  required  modified  retrospective  approach  and  utilizing  the
effective date as its date of initial application. As a result, prior periods are presented in accordance with the previous guidance in ASC Topic 840, Leases.

At  the  inception  of  an  arrangement,  the  Company  determines  whether  an  arrangement  is  or  contains  a  lease  based  on  the  unique  facts  and  circumstances
present in the arrangement. Most leases with a term greater than one year are recognized on the consolidated balance sheet as right-of-use assets and short-
term  and  long-term  lease  liabilities,  as  applicable.  The  Company  has  elected  not  to  recognize  leases  with  terms  of  12  months  or  less  on  the  consolidated
balance sheets. The Company typically only includes an initial lease term in its assessment of a lease arrangement. Options to renew a lease are not included
in the Company’s assessment unless there is reasonable certainty that the Company will renew. The Company monitors its plans to renew its material leases
on a quarterly basis.

Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected remaining
lease term. Certain adjustments to the right-of-use asset may be required for items such as incentives received. The interest rate implicit in the Company’s
leases is typically not readily determinable. As a result, the Company utilizes its incremental borrowing rate to discount lease payments, which reflects the
fixed rate at which the Company could borrow on a collateralized basis the amount of the lease payments in the same currency, for a similar term, in a similar
economic environment. In its transition to ASC 842, the Company utilized the remaining lease term of its leases in determining the appropriate incremental
borrowing rates.

In accordance with ASC 842, components of a lease should be allocated between lease components (e.g., land, building, etc.) and non-lease components (e.g.,
common area maintenance, consumables, etc.). The fixed and in-substance fixed contract consideration must be allocated based on the respective relative fair
values to the lease components and non-lease components.

Although  separation  of  lease  and  non-lease  components  is  otherwise  required,  an  expedient  is  available  whereby  the  entity  may  account  for  each  lease
component and related non-lease component together as a single lease component. For new and amended leases for office and laboratory space beginning in
2019 and after, the Company has elected to account for the lease and non-lease components together as a single lease component for all underlying assets and
allocate all of the contract consideration to the lease component only.

F-13

 
 
ASC 842 provides several optional practical expedients in transition. The Company elected the package of practical expedients which allows the Company to
not  reassess  its  existing  conclusions  on  lease  identification,  classification,  and  initial  direct  costs.  Further,  the  Company  elected  the  hindsight  practical
expedient and utilized the short-term lease exemption for all leases with an original term of 12 months or less, for purposes of applying the recognition and
measurement  requirements  of  the  new  standard.  The  Company  also  elected  the  practical  expedient  which  allows  it  to  not  separate  lease  and  non-lease
components for all its current office and laboratory leases.

The adoption of the new standard on January 1, 2019 resulted in the recognition of operating lease liabilities of $20.6 million, and right-of-use assets of $22.3
million on the Company’s consolidated balance sheet relating to its leases. Further, an adjustment to retained earnings of $0.3 million was recognized due to
the use of hindsight being applied in updating the lease term for the Company’s property leases. The adoption of the standard did not have a material effect on
the Company’s consolidated statements of operations and comprehensive loss or consolidated statements of cash flows.

Refer to Note 10 for the Company’s current lease commitments.

In June 2018, the Financial Accounting Standards Board (“FASB”) issued ASU 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to
Nonemployee  Share-Based  Payment  Accounting,  which  simplified  the  accounting  for  share-based  payments  to  nonemployees  by  aligning  it  with  the
accounting for share-based payments to employees, with certain exceptions. The Company’s adoption of the new standard on January 1, 2019 did not have a
material effect on the Company’s consolidated financial statements.

Recent Accounting Pronouncements – Issued but not yet adopted

In  December  2019,  the  FASB  issued  ASU  2019-12,  Income  Taxes  (Topic  740):  Simplifying  the  Accounting  for  Income  Taxes  (“ASU  2019-12”).  The
amendments  in  ASU  2019-12  are  effective  for  fiscal  years  beginning  after  December  15,  2020,  including  interim  periods  therein.  Early  adoption  of  the
standard  is  permitted.  The  Company  does  not  anticipate  that  the  adoption  of  ASU  2019-12  will  have  a  material  effect  on  the  Company’s  consolidated
financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for
Fair  Value  Measurement  (“ASU  2018-13”).  The  new  standard  removes  certain  disclosures,  modifies  certain  disclosures  and  adds  additional  disclosures
related  to  fair  value  measurement.  The  new  standard  was  effective  beginning  January  1,  2020  and  early  adoption  is  permitted.  The  Company  does  not
anticipate that the adoption of ASU 2018-13 will have a material effect on its disclosures upon adoption.

In  June  2016,  the  FASB  issued  ASU  2016-13,  Financial  Instruments—Credit  Losses  (Topic  326):  Measurement  of  Credit  Losses  on  Financial
Instruments (“ASU 2016-13”). The standard changes how credit losses are measured for most financial assets and certain other instruments. For trade and
other receivables, the standard requires the use of a new forward-looking “expected credit loss” model that generally will result in the earlier recognition of
allowances for losses. For available-for-sale debt securities with unrealized losses, the standard now requires allowances to be recorded instead of reducing
the amortized cost of the investment. The new standard also requires new disclosures and was effective beginning January 1, 2020. With certain exceptions,
the guidance is applied using a modified retrospective approach by reflecting adjustments through a cumulative-effect impact to retained earnings as of the
beginning of the fiscal year of adoption. The Company does not anticipate that the adoption of ASU 2016-13 will have a material effect on the Company’s
consolidated financial statements.

The amortized cost of available-for-sale securities is adjusted for amortization of premiums and accretion of discounts to maturity. At December 31, 2019 and
2018, the balance in the Company’s accumulated other comprehensive income (loss) was composed of activity related to the Company’s available-for-sale
marketable securities. There were no material realized gains or losses in the years ended December 31, 2019, 2018 or 2017 and, as a result, the Company did
not  reclassify  any  amounts  out  of  accumulated  other  comprehensive  income  (loss)  during  these  periods.  The  Company  did  not  have  any  securities  in  a
material unrealized loss position at December 31, 2019 or 2018.

The Company's available-for-sale securities that are classified as short term marketable securities in the consolidated balance sheet mature within one year or
less  as  of  the  balance  sheet  date.  Available-for-sale  securities  that  are  classified  as  noncurrent  in  the  consolidated  balance  sheet  mature  after  one  year  but
within five years from the balance sheet date. At December 31, 2019 and 2018, the Company did not hold any investments that matured beyond five years.

4.

Fair Value Measurements

The  Company  classifies  fair  value-based  measurements  using  a  three-level  hierarchy  that  prioritizes  the  inputs  used  to  measure  fair  value.  This  hierarchy
requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value
are as follows: Level 1, quoted market prices in active markets for identical assets or liabilities; Level 2, observable inputs other than quoted market prices
included in Level 1, such as quoted market prices for markets that are not active or other inputs that are observable or can be corroborated by observable
market  data;  and  Level  3,  unobservable  inputs  that  are  supported  by  little  or  no  market  activity  and  that  are  significant  to  the  fair  value  of  the  assets  or
liabilities, including certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

The  Company’s  financial  assets,  which  include  cash  equivalents  and  marketable  securities,  have  been  initially  valued  at  the  transaction  price,  and
subsequently revalued at the end of each reporting period, utilizing third-party pricing services or other observable market data. The pricing services utilize
industry standard valuation models and observable market inputs to determine value. After completing its validation procedures, the Company did not adjust
or override any fair value measurements provided by the pricing services as of December 31, 2019 or 2018.

Income Taxes

The Company did not record net income tax benefits for the operating losses incurred during the periods presented due to the uncertainty of realizing a tax
benefit from those losses. Accordingly, any benefit recorded related to these deferred tax assets was offset by a valuation allowance reflecting management’s
conclusion that realization of those assets was not more likely than not.

A reconciliation of the federal statutory income tax rate and the Company’s effective income tax rate is as follows:

Federal statutory income tax rate
State income taxes
Research and development tax credits

As of December 31, 2019, the Company had federal and state net operating loss carryforwards of $229.9 million and $236.8 million, respectively.  As of
December 31, 2019, approximately $193.0 million of the Company’s federal net operating loss carryforward can be carried forward indefinitely while the
remaining federal net operating loss of $36.9 million  begins to expire in 2034. As of December 31, 2019, the Company had federal and state research and
development and other credit carryforwards of approximately $12.6 million and $8.7 million, which begin to expire in 2035 and 2031, respectively.

The  Company  evaluated  the  expected  realizability  of  its  net  deferred  tax  assets  and  determined  that  there  was  significant  negative  evidence  due  to  its  net
operating loss position and insufficient positive evidence to support the realizability of these net deferred tax assets. The Company concluded it is more likely
than not that its net deferred tax assets would not be realized in the future; therefore, the Company has provided a full valuation allowance against its net
deferred tax asset balance as of December 31, 2019 and 2018. The valuation allowance increased by $34.5 million in 2019, $28.7 million in 2018 and $14.8
million in 2017.

Utilization of the net operating loss and research and development credit carryforwards may be subject to a substantial annual limitation under Section 382 of
the Internal Revenue Code of 1986, as amended, due to ownership changes that have occurred previously or that could occur in the future. These ownership
changes may limit the amount of net operating loss and research and development credit carryforwards that can be utilized annually to offset future taxable
income  and  tax  expense,  respectively.  The  Company  has  not  yet  conducted  a  study  to  assess  whether  a  change  of  control,  as  defined  in  Section  382,  has
occurred or whether there have been multiple changes in control since inception.

As  of  December  31,  2019,  the  Company  had  not  identified  any  unrecognized  tax  benefits.  The  Company  files  income  tax  returns  in  the  U.S.  federal  tax
jurisdiction  and  Massachusetts  and  various  other  state  tax  jurisdictions.  The  Company  is  subject  to  examination  by  the  Internal  Revenue  Service  and
Massachusetts taxing authorities. The returns in these jurisdictions since inception remain open for examination; however, there are currently no pending tax
examinations.

Commitments and Contingencies

In July 2014, the Company licensed from Caribou Biosciences, Inc. (“Caribou”) certain IP (the “Caribou License”) and entered into an arrangement under
which Caribou provided research and development services. On October 17, 2018, the Company initiated an arbitration proceeding against Caribou, asserting
that Caribou is violating the terms and conditions of the Caribou License, as well as other contractual and legal rights, by using and seeking to license to third
parties  two  patent  families  (described  in,  for  instance,  PCT  No.  PCT/US2016/015145  and  PCT  No.  PCT/US2016/064860,  and  related  patents  and
applications) relating to specific structural or chemical modifications of guide RNAs (“gRNA”s), that were purportedly invented or controlled by Caribou, in
the Company’s exclusive human therapeutic field. Caribou asserted that the two families of IP are outside the scope of the Company’s field of use under the
license rights granted to the Company under the Caribou License. In accordance with the Caribou License, the Company submitted a demand for arbitration
seeking among other relief a declaration that the disputed IP was included within the scope of its field of use under the Caribou License.

On September 26, 2019, the Company announced that the arbitration panel issued an interim award concluding that both the structural and chemical gRNAs
modification  technologies  were  exclusively  licensed  to  the  Company  by  Caribou  pursuant  to  the  Caribou  License.  After  concluding  that  the  chemical
modification  technology  was  within  the  scope  of  the  Company’s  exclusive  license  from  Caribou,  the  arbitration  panel  nevertheless  noted  that  its  decision
could delay or otherwise adversely impact the development of these modified gRNAs as human therapeutics. It also noted that the Company currently is not
using these modified gRNAs in any of its active programs. Thus, solely with respect to the particular modified gRNAs, the arbitration panel stated that it will
declare that Caribou has an equitable “leaseback,” which it described as exclusive, perpetual and worldwide (the “Caribou Award”). The panel instructed the
parties to negotiate the terms of the Caribou Award, including Caribou’s future payments to the Company for the same, but the parties’ negotiations reached
an impasse.

F-18

 
 
 
On February 6, 2020, after considering additional submissions from the parties, the panel clarified that the Caribou Award is limited to one particular on-
going Caribou program, which seeks to develop a chimeric antigen receptor (“CAR”) T (“CAR-T”) product directed at CD19. The panel instructed the parties
to seek to negotiate terms based on this scope. Accordingly, the Caribou Award will be subject to terms, including Caribou’s future payments to the Company
to be negotiated by the parties or, if unsuccessful, adjudicated in additional arbitration or judicial proceedings.

Pursuant  to  the  September  2019  interim  award,  the  Caribou  Award  by  the  panel  does  not  include  the  structural  guide  modifications  IP  at  issue  in  the
arbitration,  any  other  IP  exclusively  licensed  or  sublicensed  by  Caribou  to  the  Company  under  the  Caribou  License  (including  but  not  limited  to  the
foundational CRISPR/Cas9 IP co-owned by the Regents of the University of California, University of Vienna and Dr. Emmanuelle Charpentier), or any other
of the Company’s IP.

Upon, and subject to the terms of, a final award, which will follow further arbitration or legal proceedings and potential additional negotiations between the
parties, Caribou could be able to use the modified gRNAs at issue for CAR-T cell human therapeutics directed at CD19. Either the Company or Caribou may
challenge the arbitration panel’s decisions under limited circumstances.

Other than with regards to the technologies in dispute, the interim award has no effect on the Company’s rights or Caribou’s obligations under the Caribou
License.

License Agreements

The Company is party to license agreements, which include contingent payments. These payments will become payable if and when certain development,
regulatory and commercial milestones are achieved. As of December 31, 2019, the satisfaction and timing of the contingent payments is uncertain and not
reasonably estimable.

Collaborations

To accelerate the development and commercialization of CRISPR/Cas9-based products in multiple therapeutic areas, the Company has formed, and intends to
seek  other  opportunities  to  form,  strategic  alliances  with  collaborators  who  can  augment  its  leadership  in  CRISPR/Cas9  therapeutic  development.  As  of
December  31,  2019  and  December  31,  2018,  the  Company’s  accounts  receivable  and  contract  liabilities  were  primarily  related  to  the  Company’s
collaborations with Novartis and Regeneron.

Costs to obtain and fulfill a contract

The Company did not incur any expenses to obtain collaboration agreements and costs to fulfill those contracts do not generate or enhance resources of the
Company. As such, no costs to obtain or fulfill a contract have been capitalized in any period.

Novartis Institutes for BioMedical Research, Inc.  

In December 2014, the Company entered into a strategic collaboration agreement with Novartis (the “2014 Novartis Agreement”), primarily focused on the
research of new ex vivo CRISPR/Cas9-edited therapies using CAR-T cells and hematopoietic stem cells (“HSCs”). The agreement was amended in December
2018 to also include research on ocular stem cells (“OSCs”). In December 2019, per the terms of the 2014 Novartis Agreement, the research term ended,
although  the  2014  Novartis  Agreement  remains  in  effect.  As  provided  in  the  agreement,  Novartis  has  selected  various  CAR-T,  HSC  and  OSC  targets  for
continued development, for which the Company will be eligible to receive milestone and royalty payments in the future.

Agreement  Structure.  Under  the  2014  Novartis  Agreement,  the  parties  agreed  to  engage  in  collaborative  research  activities  using  the  Company’s
CRISPR/CAS9 platform to identify and research therapeutic, prophylactic and palliative products and services relating to the following applications: a) ex
vivo  HSCs  and  b)  ex  vivo  CAR-T  cells.  In  addition,  in  the  last  two  years  of  the  collaboration  term,  Novartis  was  permitted  to  engage  in  research  and
development of a limited number of in vivo targets using the Company’s platform.

Scope of Collaboration. During the five-year research term, the parties researched potential therapeutic, prophylactic and palliative ex vivo applications  of
CRISPR/Cas9  technology  in  HSCs  and  CAR-T  cells.  Research  expenses  incurred  by  the  Company  in  support  of  the  collaboration  were  reimbursed  by
Novartis.

HSC  Program.  The  Company  and  Novartis  agreed  to  collaborate  exclusively  with  each  other  during  the  research  term  to  conduct  research  on  ex  vivo
applications of CRISPR/Cas9 technology for HSC targets under a research plan agreed upon by both parties. At the end of the research term in December
2019, this exclusive HSC research collaboration ended. Within the ex vivo HSC therapeutic space, Novartis obtained exclusive rights to research and develop
human therapeutics for a limited number of HSC targets, which were selected by Novartis in a series of selection windows.

During the research term, the Company had the right to choose a limited number of HSC targets for its exclusive development and commercialization per the
specified selection schedule. Following these selections by Novartis and the Company, Novartis had the right to research an additional limited number of non-
selected HSC targets on a non-exclusive basis, but Novartis did not exercise this right. Because the research term has ended, the parties can no longer select
additional exclusive HSC targets, and Novartis has an exclusive license to research, develop and commercialize human therapeutic products directed to its
selected HSC targets. Novartis assumed sole responsibility for developing and commercializing human therapeutic products for the HSC targets it selected
arising from the Company’s collaboration and is solely responsible for the costs and expenses of developing, manufacturing and commercializing its HSC
products. To maintain its exclusive license on a target-by-target basis, Novartis is required to use commercially reasonable efforts to research, develop and
commercialize at least one HSC product directed to each of their selected HSC targets. In 2019, Novartis announced that it had completed investigational new
drug  (“IND”)-enabling  studies  in  support  of  a  potential  IND  on  a  program  targeting  sickle  cell  disease  that  leveraged  the  Company’s  CRISPR/Cas  9
technology. The Company is entitled to receive a $5.0 million payment related to this regulatory milestone upon filing the IND.

CAR-T Program. The Company and Novartis also agreed to collaborate exclusively with each other during the research term on research directed to applying
CRISPR/Cas9 technology to CAR-T cell targets under a research plan agreed upon by both parties. At the end of the research term in December 2019, this
exclusive research collaboration ended. Under the 2014 Novartis Agreement, Novartis assumed sole responsibility for developing human therapeutic products
for the limited number of CAR targets it selected arising from its collaboration with the Company and is solely responsible for the costs and expenses of
developing, manufacturing and commercializing its selected targets. Novartis has an exclusive license to research, develop and commercialize CAR products
directed to its selected CAR-T cell targets. To maintain its exclusive license on a target-by-target basis, Novartis is required to use commercially reasonable
efforts to research, develop and commercialize at least one CAR-T cell product directed to each of its selected CAR targets.

Governance.  The  parties  formed  HSC  and  CAR-T  cell  steering  committees  with  responsibility  for  oversight  of  these  respective  research  programs  and
approval of the associated research plans. Beginning in December 2018, the HSC steering committee also became responsible for the OSC program (see the
section below entitled “2018 Amendment to the Agreement”). These steering committees in turn were overseen by a joint steering committee and comprised
an equal number of representatives from each party. The steering committees terminated upon completion of the research term in December 2019.

Financial Terms. The Company received an upfront technology access payment from Novartis of $10.0 million in January 2015 and was entitled to additional
technology access fees of $20.0 million and quarterly research payments of $1.0 million, or up to $20.0 million in the aggregate, during the five-year research
term. As of December 31, 2019, the Company has received $20.0 million in technology access fees and $19.0 million in research payments related to these
programs. In addition, for each Novartis product under the collaboration (whether HSC or CAR-T cell product, and beginning as of December 2018, an OSC
product), subject to certain conditions, the Company may be eligible to receive (i) up to $30.3 million in development milestones, including for the filing of an
IND  application  and  for  the  dosing  of  the  first  patient  in  each  of  Phase  IIa,  Phase  IIb  and  Phase  III  clinical  trials,  (ii)  up  to  $50.0  million  in  regulatory
milestones  for  the  product’s  first  indication,  including  regulatory  approvals  in  the  U.S.  and  the  European  Union  (“EU”),  (iii)  up  to  $50.0  million  in
regulatory milestones for the product’s second indication, if any, including U.S. and EU regulatory approvals, (iv) royalties on net sales in the mid-single
digits, and (v) net sales milestone payments of up to $100.0 million.

Equity  Investments.  Additionally,  at  the  inception  of  the  arrangement  at  which  time  the  Company  was  a  privately  held  company,  Novartis  invested
$9.0 million to purchase the Company’s Class A-1 and Class A-2 Preferred Units (the “Preferred Units”). The difference between the cash proceeds received
from Novartis for the units and the $11.6 million estimated fair value of those units at the date of issuance was determined to be $2.6 million. Accordingly,
$2.6 million of the upfront technology access payment was allocated to record the Preferred Units purchased by Novartis at fair value.

License Grant to Novartis. In the 2014 Novartis Agreement, the Company granted to Novartis a license to its CRISPR/Cas9 platform technology, including a
sublicense to certain platform rights licensed from Caribou, that is exclusive in the ex vivo HSC, CAR-T cell and in vivo fields with respect to each target
selected  by  Novartis  pursuant  to  the  agreement  and  the  research  plan  as  long  as  Novartis  continues  to  use  commercially  reasonable  efforts  to  research,
develop, and commercialize CRISPR-edited products directed to such targets.

License Grant to Intellia. In the 2014 Novartis Agreement, prior to the Novartis Amendment described below, Novartis granted the Company a non-exclusive
license  to  its  IP  covering  a  small  molecule  for  HSC  expansion  and  to  its  lipid  nanoparticle  (“LNP”)  platform  technology  to  research,  develop  and
commercialize HSC and in vivo genome editing products, respectively, in the 2014 Novartis Agreement.

Intellectual Property. IP that the Company develops within the collaboration related to the Company’s CRISPR/Cas9 platform will be owned solely by the
Company, while all other IP developed within the collaboration, including IP covering products arising from the collaboration, will be jointly owned by the
Company and Novartis.

F-21

 
 
2018 Amendment to the Agreement

In December 2018, the Company entered into an amendment to this agreement with Novartis (the “Novartis Amendment”) which expanded the scope of the
2014 Novartis Agreement to include the ex vivo development of CRISPR/Cas9-based cell therapies using limbal stem cells, a type of OSC, primarily against
gene targets selected by Novartis in exchange for a one-time payment of $10.0 million which the Company received in December 2018. The governance,
license rights and development responsibilities, as well as milestones and royalties, associated with any OSC program and product follow those for the HSC
programs and products. Because the research term has ended, as with the HSC programs, the parties’ exclusive research collaboration for limbal stem cells
has ended, and Novartis has an exclusive license to research, develop and commercialize OSC products directed to a limited number of OSC targets. As part
of the Novartis Amendment, Intellia rights to Novartis’ LNP technology were expanded to include use in all genome editing applications in both in vivo and
ex vivo settings.

Term  and  Termination.  The  term  of  the  2014  Novartis  Agreement  expires  on  the  later  of  (i)  the  expiration  of  Novartis’  payment  obligations  under  the
agreement and (ii) the date of expiration of the last-to-expire of the patent rights licensed to the Company or Novartis under the agreement. Novartis’ royalty
payment obligations expire on a country-by-country and product-by-product basis upon the later of (i) the expiration of the last valid claim of the royalty-
bearing patents covering such product in such country or (ii) ten years after the first commercial sale of such product in such country. The Company may
terminate the agreement if Novartis or its affiliates institute a patent challenge against its IP rights, and all improvements thereto, licensed to Novartis under
the  agreement.  Novartis  may  terminate  the  agreement,  without  cause,  upon  90  days’  written  notice  to  the  Company  subject  to  certain  conditions  and
continuing obligations. Either party may terminate the agreement in the event of the other party’s uncured material breach or bankruptcy - or insolvency-
related events.

Accounting  Analysis.  The  Company  concluded  that  the  2014  Novartis  Agreement  and  the  Novartis  Amendment  are  subject  to  ASC  606  and  assessed  its
accounting for them accordingly. The Company evaluated the promised goods and services under the 2014 Novartis Agreement and determined that it had
two performance obligations: (1) a combined performance obligation representing a series of distinct goods and services including the licenses to research,
develop and commercialize HSC and LSC products and their associated research activities and the licenses to research, develop and commercialize CAR-T
cell products and their associated research activities; and (2) the Preferred Units.

The  Company  determined  that  the  transaction  price  of  the  2014  Novartis  Agreement  was  $59.0  million  consisting  of  the  following  consideration:  (1)  the
upfront  technology  access  payment  of  $10.0  million;  (2)  the  additional  technology  access  fees  of  $20.0  million;  (3)  the  Company’s  estimate  of  variable
consideration of $20.0 million related to the quarterly research payments; and (4) the payment for the Preferred Units of $9.0 million. None of the clinical or
regulatory milestones were included in the transaction price, as all milestone amounts were fully constrained. As part of its evaluation of the constraint, the
Company considered numerous factors, including that receipt of the milestones is outside the control of the Company and contingent upon future regulatory
progress and the licensee’s efforts. Any consideration related to sales-based milestones and royalties will be recognized when the related sales occur as they
were determined to relate predominantly to the licenses granted to Novartis and therefore have also been excluded from the transaction price. The Company
will re-evaluate the transaction price in each reporting period and when events whose outcomes are resolved or other changes in circumstances occur.

The Company first allocated $11.6 million of the transaction price to the Preferred Units to record the Preferred Units purchased by Novartis at fair value. The
Company then allocated the remaining $47.4 million of the transaction price to the remaining combined performance obligation of the licenses and associated
research  activities  for  HSC  and  CAR-T  cell  products.  Revenue  allocated  to  the  combined  performance  obligation  of  the  licenses  and  associated  research
activities for HSC and CAR-T cell products is being recognized using a time elapsed inputs method over  a  period  of  five  years,  which,  in  management’s
judgment, is the best measure of progress towards satisfying the performance obligation as this method provides the most faithful depiction of the entity’s
performance in transferring control of the goods and services promised to Novartis and represents the Company’s best estimate of the period of the obligation.

F-22

 
 
The Company determined that there is only one combined performance obligation identified under the Novartis Amendment, representing a series of distinct
goods  and  services  including  the  licenses  to  research,  develop  and  commercialize  products  using  LSCs  and  their  associated  research  and  development
services related to the research, development and commercialization of products using LSCs, and allocated the $10.0 million transaction price accordingly.
Revenue allocated to this performance obligation is being recognized using a time elapsed inputs method over a period of one year, which, in management’s
judgment, is the best measure of progress towards satisfying the performance obligation as this method provides the most faithful depiction of the entity’s
performance in transferring control of the goods and services promised to Novartis and represents the Company’s best estimate of the period of the obligation.

Revenue Recognition: Collaboration Revenue. Through December 31, 2019, excluding amounts allocated to Novartis’ purchase of the Company’s Preferred
Units, the Company had recorded a total of $57.4 million in cash and accounts receivable under the 2014 Novartis Agreement and the Novartis Amendment.
Through December 31, 2019, the Company has recognized $57.4 million of collaboration revenue, including $18.5 million in the year ended December 31,
2019,  $10.3  million  in  the  year  ended  December  31,  2018,  and  $9.3  million  in  the  year  ended  December  31,  2017,  in  the  consolidated  statements  of
operations  and  comprehensive  loss  related  to  the  2014  Novartis  Agreement  and  the  Novartis  Amendment.  As  of  December  31,  2019,  the  aggregate
transaction price had been recognized in full.

As of the periods ended December 31, 2019 and 2018, the Company had accounts receivable of $1.0 million and $6.0 million, respectively, related to this
agreement. As of December 31, 2019, the Company had no deferred revenue related to this agreement. As of December 31, 2018, the Company had deferred
revenue of $14.5 million related to this agreement.

Regeneron Pharmaceuticals, Inc.

In April 2016, the Company entered into a license and collaboration agreement with Regeneron (the “Regeneron Agreement”).

Agreement Structure. The Regeneron Agreement has two principal components: i) a product development component under which the parties will research,
develop  and  commercialize  CRISPR/Cas-based  therapeutic  products  primarily  focused  on  genome  editing  in  the  liver,  and  ii)  a  technology  collaboration
component, pursuant to which the Company and Regeneron will engage in research and development activities aimed at discovering and developing novel
technologies and improvements to CRISPR/Cas technology to enhance the Company’s genome editing platform. Under this agreement, the Company also
may  access  the  Regeneron  Genetics  Center  and  proprietary  mouse  models  to  be  provided  by  Regeneron  for  a  limited  number  of  the  Company’s  liver
programs.

Scope of Collaboration. Under the terms of the six-year collaboration, Regeneron may obtain exclusive rights for up to ten targets to be chosen by Regeneron
during  the  collaboration  term,  subject  to  a  target  selection  process  and  various  adjustments  and  limitations  set  forth  in  the  agreement.  Of  these  ten  total
targets,  Regeneron  may  select  up  to  five  non-liver  targets,  while  the  remaining  targets  must  be  focused  in  the  liver.  Certain  non-liver  targets  from  the
Company’s  ongoing  and  planned  research  at  the  time,  as  well  as  any  targets  included  in  another  of  the  Company’s  collaborations,  are  excluded  from  this
collaboration.  At  the  inception  of  the  agreement,  Regeneron  selected  the  first  of  its  ten  targets,  transthyretin  amyloidosis  (“ATTR”),  which  is  subject  to  a
Co/Co agreement between the Company and Regeneron, the general terms and conditions for which were outlined within the Regeneron Agreement.

Research Collaboration. Research activities under the collaboration will be governed by evaluation and research and development plans that will outline the
parties’  responsibilities  under,  anticipated  timelines  of  and  budgets  for,  the  various  programs.  The  Company  will  assist  Regeneron  with  the  preliminary
evaluation of its selected liver targets, and Regeneron will be responsible for preclinical research and conducting clinical development, manufacturing and
commercialization of products directed to each of its exclusive targets. The Company may assist, as requested by Regeneron, with the later discovery and
research of product candidates directed to any selected target. For each selected target, Regeneron is required to use commercially reasonable efforts to submit
regulatory filings necessary to achieve IND acceptance for at least one product directed to each applicable target, and following IND acceptance for at least
one product, to develop and commercialize such product.

F-23

 
 
Reserved  Liver  Targets.  The  Company  retains  the  exclusive  right  to  solely  develop  products  via  CRISPR/Cas  genome  editing  directed  against  certain
specified genetic targets. During the collaboration term and subject to a target selection process, the Company has the right to choose additional liver targets
for its own development using commercially reasonable efforts. Certain targets that either the Company or Regeneron select during the term may be subject to
further Co/Co agreements at the Company or Regeneron’s option, as applicable, which either can exercise pursuant to defined conditions.

Governance.  Under  the  Regeneron  Agreement,  the  parties  formed  a  joint  steering  committee,  which  is  responsible  for  setting  research  objectives  and
overseeing  the  general  strategies  and  research  and  development  activities  undertaken  by  the  parties.  Additionally,  under  the  Co/Co  agreement  directed  to
ATTR (the “ATTR Co/Co”), the parties formed a Joint Development and Commercialization Committee (“JDCC”) to oversee all profit share products under
the  Co/Co  agreement  as  discussed  below.  The  JDCC  has  responsibility  for  overseeing  the  development,  manufacture,  regulatory  matters,  and
commercialization (including pricing and reimbursement) of ATTR, as the first profit share product under the Regeneron agreement.

Financial Terms. The Company received a nonrefundable upfront payment of $75.0 million. In addition, on Regeneron programs that are not subject to Co/Co
agreements the Company may be eligible to earn, on a per-licensed target basis, (i) up to $25.0 million in development milestones, including for the dosing of
the first patient in each of Phase I, Phase II and Phase III clinical trials, (ii) up to $110.0 million in regulatory milestones, including for the acceptance of a
regulatory filing in the U.S., and for obtaining regulatory approval in the U.S. and in certain other identified countries, and (iii) up to $185.0 million in sales-
based milestone payments. The Company is also eligible to earn royalties ranging from the high single digits to low teens, in each case, on a per-product
basis,  which  royalties  are  potentially  subject  to  various  reductions  and  offsets  and  incorporate  the  Company’s  existing  low-  to  mid-single-digit  royalty
obligations under a license agreement with Caribou.

Equity Investments. In connection with this collaboration, Regeneron purchased $50.0 million of the Company’s common stock in a private placement under a
Stock Purchase Agreement concurrent with the Company’s initial public offering (“IPO”).

Term and Termination. The research collaboration term ends in April 2022, except that Regeneron may make a one-time payment of $25.0 million to extend
the term for an additional two-year  period.  The  Regeneron  Agreement  will  continue  until  the  date  when  no  royalty  or  other  payment  obligations  are  due,
unless  earlier  terminated  in  accordance  with  the  terms  of  the  agreement.  Regeneron’s  royalty  payment  obligations  expire  on  a  country-by-country  and
product-by-product basis upon the later of (i) the expiration of the last valid claim of the royalty-bearing patents covering such product in such country, (ii) 12
years from the first commercial sale of such product in such country, or (iii) the expiration of regulatory exclusivity for such product. The Company may
terminate  the  Regeneron  Agreement  on  a  target-by-target  basis  if  Regeneron  or  any  of  its  affiliates  institutes  a  patent  challenge  against  the  Company’s
CRISPR/Cas or certain other background patent rights or does not proceed with the development of a product directed to a selected target within specified
periods of time. Regeneron may terminate the agreement, without cause, upon 180 days written notice to the Company, either in its entirety or on a target-by-
target basis, in which event, certain rights in the terminated targets and associated IP revert to the Company, as described in the agreement. Following such
termination,  the  Company  may  owe  Regeneron  royalties,  in  certain  circumstances,  up  to  mid-single  digits  on  any  terminated  targets  that  the  Company
subsequently commercializes on a product-by-product basis for a period of 12 years after the first commercial sale of any such products. Either party may
terminate the Regeneron Agreement either in its entirety or with respect to the research collaboration or one or more of the targets selected by Regeneron, in
the event of the other party’s uncured material breach.

Co-Development and Co-Promotion Agreement. In July 2018, the Company and Regeneron finalized the form of the Co/Co agreement that will be used as the
basis  for  each  Co/Co  agreement  directed  to  a  target.  Simultaneously,  the  Company  and  Regeneron  executed  the  Co/Co  agreement  directed  to  the  first
collaboration  target,  ATTR,  for  which  the  Company  is  the  clinical  and  commercial  Lead  Party  (see  below)  and  Regeneron  is  the  Participating  Party  (see
below).

F-24

 
 
 
Co-Development and Co-Promotion: Agreement Structure Under the Regeneron Agreement, Regeneron has the right to exercise at least five options to enter
into  a  Co/Co  agreement  for  the  Company’s  liver  targets  (other  than  the  Company’s  reserved  liver  targets),  while  the  Company  may  exercise  at  least  one
option to enter into a Co/Co agreement for Regeneron’s liver targets, the exact number of options being subject to certain conditions of the target selection
process. Each option to enter into a Co/Co agreement must be exercised (or forfeited) once a target reaches a defined preclinical stage. Within 15 days of
exercising  the  option,  the  party  exercising  the  option  must  pay  $1.5  million  to  the  other  party  as  compensation  for  prior  work.  The  ATTR  program  was
exempted from this payment. One party will be the “Lead Party” and the other party the “Participating Party”. The Lead Party shall have control and primary
responsibility  for  the  development,  manufacturing,  regulatory  and  commercial  activities.  The  Participating  Party  shall  have  the  right  to  consult  on  these
activities through its participation on the JDCC and will have the right to co-fund development and commercialization activities in exchange for a share of
profits. In general, under each Co/Co agreement, the parties will share equally in worldwide development costs and profits of any future products. Prior to
reaching  a  specific  development  milestone,  the  Participating  Party  may  elect  to  reduce  its  share  of  worldwide  development  costs  and  profits  by  50%.
Pursuant to the ATTR Co/Co, on December 13, 2019, Regeneron informed the Company that it would exercise its rights under the ATTR Co/Co agreement to
modify its share of worldwide development costs and profits from 50% to 25%, effective six months after its notice.

Co-Development and Co-Promotion: Termination. Either party may terminate by providing 180 days written notice. If the Company terminates, the product
becomes  a  Regeneron  product,  and  is  subject  to  all  future  milestone  and  royalty  payment  obligations  under  the  Regeneron  Agreement.  If  Regeneron
terminates and has contributed at least $5 million in development costs under the Co/Co agreement, the Company will pay low- to mid-single digit royalties
on the net sales of the product, depending on co-funding percentage, stage at termination and, if any, Regeneron IP incorporated into the product.

Accounting Analysis. The Company determined that the Regeneron Agreement is within the scope of ASC 606. The Company evaluated the promised goods
and  services  under  the  Regeneron  Agreement  and  determined  that  the  Regeneron  Agreement  included  three  performance  obligations:  (1)  a  combined
performance obligation including the licenses to targets and the associated research activities and evaluation plans; (2) a combined performance obligation
including the technology collaboration and associated research activities; and (3) the common stock.

The Company also concluded that the ATTR Co/Co agreement meets the definition of a collaborative arrangement per ASC 808, which is outside of the scope
of ASC 606. Since ASC 808 does not provide recognition and measurement guidance for collaborative arrangements, the Company has analogized to ASC
606.  As  such,  the  Company  classifies  payments  received  or  made  under  the  cost  sharing  provisions  of  the  ATTR  Co/Co  agreement  as  a  component  of
revenues in the consolidated statements of operations and comprehensive loss.

Under the Regeneron Agreement, the Company determined that the transaction price was $125.0 million, consisting of the following consideration: (1) the
nonrefundable upfront payment of $75.0 million; and (2) the payment for the common stock of $50.0 million. None of the clinical or regulatory milestones
were  included  in  the  transaction  price,  as  all  milestone  amounts  were  fully  constrained.  As  part  its  evaluation  of  the  constraint,  the  Company  considered
numerous factors, including that receipt of the milestones is outside the control of the Company and contingent upon success in future regulatory progress and
the  licensee’s  efforts.  Any  consideration  related  to  sales-based  milestones  and  royalties  will  be  recognized  when  the  related  sales  occur  as  they  were
determined to relate predominantly to the licenses granted to Regeneron and therefore have also been excluded from the transaction price. The Company will
re-evaluate the transaction price in each reporting period and when events whose outcome are resolved or other changes in circumstances occur.

F-25

 
 
The Company first allocated $50.0 million of the transaction price to the common stock. The common stock was sold at its standalone selling price and the
Company concluded that the total discount inherent in the arrangement is entirely attributable to the combined performance obligation including the licenses
to  targets  and  associated  research  activities  and  evaluation  plans  and  the  combined  performance  obligation  including  the  technology  collaboration  and
associated research activities. As such, the remaining $75.0 million of the transaction price was allocated to the combined performance obligation including
the licenses to targets and associated research activities and evaluation plans and the combined performance obligation including the technology collaboration
and  associated  research  activities  on  a  relative  standalone  selling  price  basis.  The  Company  estimated  the  standalone  selling  price  of  each  combined
performance  obligation  by  taking  into  consideration  internal  estimates  of  research  and  development  personnel  needed  to  perform  the  research  and
development  services,  estimates  of  expected  cash  outflows  to  third  parties  for  services  and  supplies,  selling  prices  of  comparable  transactions  and  typical
gross profit margins. As a result of this evaluation, the Company allocated $63.8 million to the combined performance obligation including the licenses to
targets  and  associated  research  activities  and  evaluation  plans  and  $11.2  million  to  the  combined  performance  obligation  including  the  technology
collaboration  and  associated  research  activities.  The  $63.8  million  allocated  to  the  combined  performance  obligation  including  the  licenses  to  targets  and
associated research activities and evaluation plans is being recognized using a time elapsed inputs method over a period of six years, which, in management’s
judgment, is the best measure of progress towards satisfying the performance obligation as this method provides the most faithful depiction of the entity’s
performance  in  transferring  control  of  the  goods  and  services  promised  to  Regeneron  and  represents  the  Company’s  best  estimate  of  the  period  of  the
obligation. The $11.2 million allocated to the combined performance obligation including the technology collaboration and associated research activities is
being recognized using a time elapsed inputs method over a period beginning with the inception of the technology collaboration in September 2016 through
the end of the arrangement, which, in management’s judgment, is the best measure of progress towards satisfying the performance obligation as this method
provides the most faithful depiction of the entity’s performance in transferring control of the goods and services promised to Regeneron and represents the
Company’s best estimate of the period of the obligation.

Revenue  Recognition:  Collaboration  Revenue.  Through  December  31,  2019,  excluding  the  amounts  allocated  to  Regeneron’s  purchase  of  the  Company’s
common  stock,  the  Company  recorded  a  $75.0  million  upfront  payment  and  $24.1  million  for  research  and  development  services  under  the  Regeneron
Agreement. As of December 31, 2019, there was approximately $28.8 million of the aggregate transaction price remaining to be recognized, which will be
recognized  ratably  through  April  2022.  As  of  December  31,  2019  and  2018,  the  Company  had  deferred  revenue  of  $28.8  million  and  $41.4  million,
respectively, and accounts receivable of $3.6 million and $1.5 million, respectively, related to this arrangement.

Through December 31, 2019, the Company has recognized $70.3 million, including $24.6 million, $20.1 million and $16.8 million of collaboration revenue
in  the  years  ended  December  31,  2019,  2018  and  2017,  respectively,  in  the  consolidated  statements  of  operations  and  comprehensive  loss  related  to  this
arrangement. This includes $12.0 million, $7.5 million, and $4.1 million representing payments from Regeneron pursuant to the ATTR Co/Co agreement,
which is accounted for under ASC 808.

Leases

In October 2014, the Company entered into an agreement to lease office and laboratory space at 130 Brookline Street in Cambridge, Massachusetts under an
operating lease agreement with a term through January 2020, with an option to extend the term of the lease for an additional five-year period. In April 2019,
the  Company  executed  an  amendment  to  the  lease  to  extend  the  term  of  the  lease  for  the  additional  five-year  period,  through  January  2025.  Upon  the
execution of the original lease, the Company provided a $0.3 million security deposit. The Company has recorded this security deposit in other assets on the
consolidated balance sheets.

In applying the ASC 842 transition guidance, the Company retained the classification of this lease as operating and recorded a lease liability and a right-of-
use asset on the ASC 842 effective date with the five-year extension included in the lease term, based on the Company’s election of the hindsight practical
expedient as the Company was reasonably certain to exercise this option term.
In March 2019, the Company entered into a separate agreement to sublease additional office and laboratory space at 130 Brookline
Street in Cambridge, Massachusetts under an operating sublease agreement with a term through April

F-26

 
 
2021, with two options to extend the agreement by one year each, for a total option period of up to two years. Upon commencement of the lease in April
2019, the Company recognized a right-of-use asset and lease liability of approximately $1.3 million.

In January 2016, the Company entered into a ten-year agreement to lease office and laboratory space at 40 Erie Street in Cambridge, Massachusetts under an
operating lease agreement, with an option to terminate the lease at the end of the sixth year and an option to extend the term of the lease for an additional
three  years.  Upon  the  execution  of  this  lease,  the  Company  provided  a  $2.2  million  security  deposit,  which  has  been  recorded  in  other  assets  on  the
consolidated balance sheets.

Throughout the term of its leases, the Company is responsible for paying certain costs and expenses, in addition to the rent, as specified in the lease, including
a proportionate share of applicable taxes, operating expenses and utilities. The variable portion of these costs are expensed as incurred and are disclosed as
variable lease cost.

In April 2016, the Company adopted the Amended and Restated 2015 Stock Option and Incentive Plan (the “2015 Plan”). The 2015 Plan provides for the
grant of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock awards, restricted stock units and other stock-based
awards. Recipients of incentive stock options and non-qualified stock options are eligible to purchase shares of the Company’s common stock at an exercise
price equal to the fair value of such stock on the grant date. Stock options granted under the 2015 Plan generally vest 25% on the first anniversary of the
original vesting date, with the balance vesting monthly over the remaining three years, unless they contain specific performance-based vesting provisions. The
maximum term of stock options granted under the 2015 Plan is ten years.  

As of December 31, 2019, there were 2,655,673 shares available for future issuance. The number of shares reserved for issuance under the 2015 Plan shall be
cumulatively increased by four percent of the number of shares of stock issued and outstanding on the immediately preceding December 31 or such lesser
number of shares of stock as determined by the board of directors.

Equity-based compensation expense is classified in the consolidated statements of operations and comprehensive loss as follows:

The weighted average grant date fair value of restricted stock, was $22.98 for restricted stock granted during 2018. There was no restricted stock granted in
2017  or  2019.  As  of  December  31,  2019,  there  was  $0.2  million  of  unrecognized  equity-based  compensation  expense  related  to  restricted  stock  that  is
expected to vest. These costs are expected to be recognized over a weighted average remaining vesting period of 1.0 year. All of the unvested restricted stock
outstanding  as  of  December  31,  2019  are  performance-based  restricted  stock  units  that  vest  upon  obtaining  certain  scientific,  financial  and  regulatory
milestones through 2020. These 71,875 restricted stock units are not included in computing the diluted (loss) earnings per share because the performance
criteria had not been met as of the end of the reporting period.

Stock Options

The weighted average grant date fair value of options, estimated as of the grant date using the Black-Scholes option pricing model, was $9.21 per option for
options granted during the year ended December 31, 2019, $15.05 per option for options granted during the year ended December 31, 2018 and $12.43 per
option  for  options  granted  during  the  year  ended  December  31,  2017.  The  total  intrinsic  value  (the  amount  by  which  the  fair  market  value  exceeded  the
exercise  price)  of  stock  options  exercised  during  the  year  ended  December  31,  2019,  2018  and  2017  was  $2.3  million,  $18.0  million,  and  $1.6  million,
respectively. Key assumptions used to apply this pricing model were as follows:

Risk-free interest rate
Expected life of options
Expected volatility of underlying stock
Expected dividend yield

Risk-free Interest Rate.  The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant with maturities approximately equal
to the option’s expected term.

Expected Dividend Yield.  The expected dividend yield assumption is based on the fact that the Company has never paid cash dividends and has no present
intention to pay cash dividends.

Expected Volatility.  The expected volatility was derived from a blend of average historical stock volatilities of several unrelated public companies within the
Company’s industry and the Company’s historical volatility, both over a period equivalent to the expected term of the stock option grants.

Expected Term.  The expected term represents the period that stock options awards are expected to be outstanding. For option grants that are considered to be
“plain vanilla,” the Company determines the expected term using the simplified method. The simplified method deems the term to be the average of the time-
to-vesting and the contractual life of the options. The Company uses the simplified method because it does not have sufficient historical option exercise data
to provide a reasonable basis upon which to estimate the expected term.

expected to be recognized over a weighted average remaining vesting period of 2.5 years.

Of the unvested stock options outstanding as of December 31, 2019, 213,750 are performance-based stock options that vest upon obtaining certain scientific,
financial and regulatory milestones through 2020. At December 31, 2019, 188,750 performance-based options are not included in computing the diluted (loss)

DESCRIPTION OF THE REGISTRANT’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF THE
SECURITIES EXCHANGE ACT OF 1934

Exhibit 4.4

The summary of the general terms and provisions of the registered securities of Intellia Therapeutics, Inc. (the “Company,” “we,” “us,” and “our”) set forth
below does not purport to be complete. It is subject to and qualified in its entirety by reference to our Second Amended and Restated Certificate of
Incorporation (“Certificate of Incorporation”) and our Second Amended and Restated Bylaws (“Bylaws”), each of which are incorporated by reference as an
exhibit to the Annual Report on Form 10-K of which this Exhibit 4.4 is a part, and by applicable law. We encourage you to read our Certificate of
Incorporation, our Bylaws and the applicable provisions of the Delaware General Corporation Law for additional information.

Authorized Capital Stock

Our authorized capital stock consists of 120,000,000 shares of common stock, par value $0.0001 per share, and 5,000,000 shares of preferred stock, par value
$0.0001 per share, all of which are undesignated preferred stock.

Common Stock

The holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of the stockholders. The holders of our
common stock do not have any cumulative voting rights. Holders of our common stock are entitled to receive ratably any dividends declared by our board of
directors out of funds legally available for that purpose, subject to any preferential dividend rights of any outstanding preferred stock. Our common stock has
no preemptive rights, conversion rights or other subscription rights, or redemption or sinking fund provisions.

In the event of our liquidation, dissolution or winding up, holders of our common stock will be entitled to share ratably in all assets remaining after payment
of all debts and other liabilities and any liquidation preference of any outstanding preferred stock. All outstanding shares are fully paid and nonassessable.

Listing

Our common stock is listed on the Nasdaq Global Market under the symbol “NTLA.”

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Computershare Trust Company, N.A.

Undesignated Preferred Stock

Our board of directors is authorized to issue up to 5,000,000 shares of undesignated preferred stock in one or more series without stockholder approval. Our
board of directors may determine the rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption
privileges and liquidation preferences, of each series of preferred stock.

The purpose of authorizing our board of directors to issue preferred stock in one or more series and determine the number of shares in the series and its rights
and preferences is to eliminate delays associated with a stockholder vote on specific issuances. Examples of rights and preferences that the Board may fix are:

•

•

dividend rights;

conversion rights;

 
 
 
 
 
 
 
•

•

•

•

•

voting rights;

terms of redemption;

liquidation preferences;

sinking fund terms; and

the number of shares constituting, or the designation of, such series, any or all of which may be greater than the rights of common stock.

No shares of preferred stock are outstanding as of the date of our Annual Report on Form 10-K with which this Exhibit 4.4 is filed as an exhibit.

Anti-Takeover Effects of Delaware Law and Provisions of Our Second Amended and Restated Certificate of Incorporation and Second Amended
and Restated Bylaws

Certain provisions of the Delaware General Corporation Law and of our second amended and restated certificate of incorporation and second amended and
restated bylaws could have the effect of delaying, deferring or discouraging another party from acquiring control of us. These provisions, which are
summarized below, are expected to discourage certain types of coercive takeover practices and inadequate takeover bids and, as a consequence, they might
also inhibit temporary fluctuations in the market price of our common stock that often result from actual or rumored hostile takeover attempts. These
provisions are also designed in part to encourage anyone seeking to acquire control of us to first negotiate with our board of directors. These provisions might
also have the effect of preventing changes in our management. It is possible that these provisions could make it more difficult to accomplish transactions that
stockholders might otherwise deem to be in their best interests. However, we believe that the advantages gained by protecting our ability to negotiate with any
unsolicited and potentially unfriendly acquirer outweigh the disadvantages of discouraging such proposals, including those priced above the then-current
market value of our common stock, because, among other reasons, the negotiation of such proposals could improve their terms.

Delaware Takeover Statute

We are subject to the provisions of Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a publicly held Delaware
corporation from engaging in a “business combination” with an “interested stockholder” for a three-year period following the time that this stockholder
becomes an interested stockholder, unless the business combination is approved in a prescribed manner. Under Section 203, a business combination between a
corporation and an interested stockholder is prohibited unless it satisfies one of the following conditions:

•

•

•

before the stockholder became interested, our board of directors approved either the business combination or the transaction which resulted in the
stockholder becoming an interested stockholder;

upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at
least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the
voting stock outstanding, shares owned by persons who are directors and also officers, and employee stock plans, in some instances, but not the
outstanding voting stock owned by the interested stockholder; or

at or after the time the stockholder became interested, the business combination was approved by our board of directors and authorized at an
annual or special meeting of the stockholders by the affirmative vote of at least two-thirds of the outstanding voting stock that is not owned by the
interested stockholder.

Section 203 defines a business combination to include:

•

•

•

any merger or consolidation involving the corporation and the interested stockholder;

any sale, transfer, lease, pledge, exchange, mortgage or other disposition involving the interested stockholder of 10% or more of the assets of the
corporation;

subject to exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested
stockholder;

 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

•

subject to exceptions, any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or
series of the corporation beneficially owned by the interested stockholder; or

the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or
through the corporation.

In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person affiliated with or controlling or controlled by the entity or person.

Provisions of our Second Amended and Restated Certificate of Incorporation and Second Amended and Restated Bylaws

Our second amended and restated certificate of incorporation and second amended and restated bylaws include a number of provisions that may have the
effect of delaying, deferring or discouraging another party from acquiring control of us and encouraging persons considering unsolicited tender offers or other
unilateral takeover proposals to negotiate with our board of directors rather than pursue non-negotiated takeover attempts. These provisions include the items
described below.

Board composition and filling vacancies. In accordance with our second amended and restated certificate of incorporation, our board is divided into three
classes serving staggered three-year terms, with one class being elected each year. Our second amended and restated certificate of incorporation also provides
that directors may be removed only for cause and then only by the affirmative vote of the holders of 75% or more of the shares then entitled to vote at an
election of directors. Furthermore, any vacancy on our board of directors, however occurring, including a vacancy resulting from an increase in the size of our
board, may only be filled by the affirmative vote of a majority of our directors then in office even if less than a quorum.

No written consent of stockholders. Our second amended and restated certificate of incorporation provides that all stockholder actions are required to be taken
by a vote of the stockholders at an annual or special meeting, and that stockholders may not take any action by written consent in lieu of a meeting. This limit
may lengthen the amount of time required to take stockholder actions and would prevent the amendment of our bylaws or removal of directors by our
stockholder without holding a meeting of stockholders.

Meetings of stockholders. Our bylaws provide that only a majority of the members of our board of directors then in office may call special meetings of
stockholders and only those matters set forth in the notice of the special meeting may be considered or acted upon at a special meeting of stockholders. Our
bylaws limit the business that may be conducted at an annual meeting of stockholders to those matters properly brought before the meeting.

Advance notice requirements. Our bylaws establish advance notice procedures with regard to stockholder proposals relating to the nomination of candidates
for election as directors or new business to be brought before meetings of our stockholders. These procedures provide that notice of stockholder proposals
must be timely given in writing to our corporate secretary prior to the meeting at which the action is to be taken. Generally, to be timely, notice must be
received at our principal executive offices not less than 90 days or more than 120 days prior to the first anniversary date of the annual meeting for the
preceding year. The notice must contain certain information specified in our bylaws.

 
 
 
 
 
 
 
 
Amendment to certificate of incorporation and bylaws. As required by the Delaware General Corporation Law, any amendment of our second amended and
restated certificate of incorporation must first be approved by a majority of our board of directors, and if required by law or our second amended and restated
certificate of incorporation, must thereafter be approved by a majority of the outstanding shares entitled to vote on the amendment, and a majority of the
outstanding shares of each class entitled to vote thereon as a class, except that the amendment of the provisions relating to stockholder action, directors,
limitation of liability and the amendment of our second amended and restated certificate of incorporation must be approved by not less than 75% of the
outstanding shares entitled to vote on the amendment, and not less than 75% of the outstanding shares of each class entitled to vote thereon as a class. Our
bylaws may be amended by the affirmative vote of a majority vote of the directors then in office, subject to any limitations set forth in the bylaws; and may
also be amended by the affirmative vote of at least 75% of the outstanding shares entitled to vote on the amendment, or, if the board of directors recommends
that the stockholders approve the amendment, by the affirmative vote of the majority of the outstanding shares entitled to vote on the amendment, in each case
voting together as a single class.

Exclusive Jurisdiction of Delaware for State Law Claims. Unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the
State of Delaware shall be the sole and exclusive forum for any state law claim for (i) any derivative action or proceeding brought on behalf of the Company,
(ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Company to the Company or the
Company’s stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law or our second amended
and restated certificate of incorporation or our bylaws, or (iv) any action asserting a claim against the Company governed by the internal affairs doctrine (the
“Delaware Forum Provision”); provided, however, that this Delaware Forum Provision does not apply to any actions arising under the Securities Act or the
Exchange Act. The Delaware Forum Provision may impose additional litigation costs on stockholders in pursuing claims covered by the Delaware Forum
Provision, particularly if the stockholders do not reside in or near the State of Delaware. Additionally, the Delaware Forum Provision may limit our
stockholders’ ability to bring a claim in a judicial forum that they find favorable for disputes with us or our directors, officers or employees, which may
discourage the filing of such lawsuits. The Court of Chancery of the State of Delaware may also reach different judgment or results than would other courts,
including courts where a stockholder considering an action may be located or would otherwise choose to bring the action, and such judgments may be more
or less favorable to us than our stockholders.

Undesignated preferred stock. Our second amended and restated certificate of incorporation provides for authorized shares of preferred stock. The existence
of authorized but unissued shares of preferred stock may enable our board of directors to render more difficult or to discourage an attempt to obtain control of
us by means of a merger, tender offer, proxy contest or otherwise. For example, if in the due exercise of its fiduciary obligations, our board of directors were
to determine that a takeover proposal is not in the best interests of us or our stockholders, our board of directors could cause shares of preferred stock to be
issued without stockholder approval in one or more private offerings or other transactions that might dilute the voting or other rights of the proposed acquirer
or insurgent stockholder or stockholder group. In this regard, our second amended and restated certificate of incorporation grants our board of directors broad
power to establish the rights and preferences of authorized and unissued shares of preferred stock. The issuance of shares of preferred stock could decrease
the amount of earnings and assets available for distribution to holders of shares of common stock. The issuance may also adversely affect the rights and
powers, including voting rights, of these holders and may have the effect of delaying, deterring or preventing a change in control of us.

Exhibit 10.21

The purpose of this Second Amended and Restated Non-Employee Director Compensation Policy (the “Policy”) of Intellia Therapeutics, Inc., a Delaware

All cash retainers will be paid quarterly, in arrears, or upon the earlier of resignation or removal of the non-employee director.  Cash retainers owing to non-
employee directors shall be annualized, meaning that with respect to non-employee directors who join the Board during the calendar year, and with respect to
all non-employee directors for 2016, such amounts shall be pro-rated based on the number of calendar days served by such director.

Equity Retainers

Initial Equity Grant: One-time option grant to each new non-employee director upon his/her election to the Board after the Effective Date to purchase 38,000
shares  of  common  stock,  par  value  $0.0001  per  share  (the  “Common Stock”).  Such  initial  equity  grant  shall  be  made  upon  the  director  first  becoming  a
director. Such initial equity grant shall vest as to 33 1/3 % of the total award one year after the date of grant and thereafter in substantially equal quarterly
installments during the three years following the grant date, subject to the director’s continued service on the Board.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
On the date of each Annual Meeting of Stockholders:  Annual option grant to each non-employee director serving on the Board immediately following the
Company’s annual meeting of stockholders to purchase 19,000 shares of Common Stock. Such annual equity grant shall vest on the earlier of the one-year
anniversary of the grant date and the Company’s next annual meeting of stockholders, subject to the director’s continued service on the Board.

All of the foregoing option grants will become immediately exercisable upon the death, disability or retirement of a director or upon a change in control of the
Company.  In addition, the form of option agreement will give directors up to one year following cessation of service as a director to exercise the options (to
the extent vested at the date of such cessation), provided that the director has not been removed for cause.

All of the foregoing options will be granted at an exercise price equal to the fair market value of a share of Common Stock on the date of grant.

Expenses

The Company shall reimburse all reasonable out-of-pocket expenses incurred by non-employee directors in attending Board and committee meetings.
