We have incurred net losses in every period since our inception and anticipate that we will incur substantial net losses in the future.

Our engineered allogeneic T cell product candidates represent a novel approach to cancer treatment that creates significant challenges for
us.

Gene-editing is a relatively new technology, and if we are unable to use this technology in our intended product candidates, our revenue
opportunities will be materially limited.

The COVID-19 global pandemic is adversely impacting our business, including our preclinical studies and clinical trials.

We are heavily reliant on our partners for access to key gene editing technology for the manufacturing and development of our product
candidates.

Our product candidates are based on novel technologies, which makes it difficult to predict the time and cost of product candidate
development and obtaining regulatory approval.
Our business is highly dependent on the success of our lead product candidates. If we are unable to advance clinical development, obtain
approval of and successfully commercialize our lead product candidates for the treatment of patients in approved indications, our business
would be significantly harmed.
Our product candidates may cause undesirable side effects or have other properties that could halt their clinical development, prevent their
regulatory approval, limit their commercial potential or result in significant negative consequences.

Our clinical trials may fail to demonstrate the safety and efficacy of any of our product candidates, which would prevent or delay regulatory
approval and commercialization.
Initial, interim and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data
become available and are subject to audit and verification procedures that could result in material changes in the final data.
We may encounter substantial delays in our clinical trials, or may not be able to conduct our trials on the timelines we expect.

If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise
adversely affected.

We face significant competition from other biotechnology and pharmaceutical companies, and our operating results will suffer if we fail to
compete effectively.

We are highly dependent on our key personnel, and if we are not successful in attracting and retaining highly qualified personnel, we may
not be able to successfully implement our business strategy.

We will need substantial additional financing to develop our products and implement our operating plans. If we fail to obtain additional
financing, we may be unable to complete the development and commercialization of our product candidates.

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

We rely on the availability of suitable donor material and other specialty raw materials, which may not be available to us on acceptable
terms or at all.

The FDA may disagree with our regulatory plan and we may fail to obtain regulatory approval of our CAR T cell product candidates.

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

If our efforts to protect the proprietary nature of the intellectual property related to our technologies are not adequate, we may not be able to
compete effectively in our market.

Item 1. Business

Overview

PART I

We are a clinical stage immuno-oncology company pioneering the development and commercialization of genetically engineered allogeneic T
cell therapies for the treatment of cancer. We are developing a pipeline of off-the-shelf T cell product candidates that are designed to target and kill cancer
cells. Our engineered T cells are allogeneic, meaning they are derived from healthy donors for intended use in any patient, rather than from an individual
patient for that patient’s use, as in the case of autologous T cells. We believe this key difference will enable us to deliver readily available treatments faster,
more reliably, at greater scale, and to more patients.

Chimeric antigen receptor (CAR) T cell therapy, a form of cancer immunotherapy, has emerged as a revolutionary and potentially curative

therapy for patients with hematologic cancers, including refractory cancers. In 2017, the first two autologous anti-CD19 CAR T cell therapies, Kymriah,
developed by Novartis International AG (Novartis), and Yescarta, developed by Kite Pharma, Inc. (Kite), were approved by the U.S. Food and Drug
Administration (FDA) for the treatment of relapsed/refractory (R/R) B-cell precursor acute lymphoblastic leukemia (ALL) (Kymriah) and R/R large B-cell
lymphoma (Yescarta). Autologous CAR T cell therapies are manufactured individually for the patient’s use by modifying the patient’s own T cells outside
the body, causing the T cells to express CARs. The entire manufacturing process is dependent on the viability of each patient’s T cells and takes
approximately two to four weeks. As seen in the registrational trials for Kymriah and Yescarta, up to 31% of intended patients ultimately did not receive
treatment primarily due to interval complications from the underlying disease during manufacturing or manufacturing failures.

Our allogeneic approach involves engineering healthy donor T cells, which we believe will allow for the creation of an inventory of off-the-

shelf products that can be delivered to a larger portion of eligible patients throughout the world. These potential benefits led our Executive Chairman, Arie
Belldegrun, M.D., FACS, who was previously the Chairman and Chief Executive Officer at Kite, and our President and Chief Executive Officer, David
Chang, M.D., Ph.D., previously Chief Medical Officer and Executive Vice President of Research and Development at Kite, to found our company with the
driving purpose of accelerating the development of allogeneic CAR T cell therapies.

We have multiple clinical trials ongoing and have a deep pipeline to further the research and development of allogeneic CAR T cell product

candidates in both hematological malignancies and solid tumors. We believe our management team’s experience in immuno-oncology and specifically in
CAR T cell therapy will help drive the rapid development and, if approved, the commercialization of potentially curative therapies for patients with
aggressive cancer.

Our Approach

Our allogeneic T cell development strategy has four key pillars: (1) engineering product candidates to minimize the risk of graft-versus-host

disease (GvHD), a condition where allogeneic T cells can recognize the patient’s normal tissue as foreign and cause damage, (2) creating a window of
persistence that may enable allogeneic T cells to expand and eradicate cancer cells in patients, (3) building a leading manufacturing platform to enable
consistent and high quality production and (4) leveraging next generation technologies to improve the functionality of allogeneic CAR T cells.

We use Cellectis, S.A. (Cellectis), TALEN gene-editing technology with the goal of limiting the risk of GvHD by engineering T cells to lack

functional T cell receptors (TCRs) that are no longer capable of recognizing a patient’s normal tissue as foreign. With the goal of enhancing the expansion
and persistence of our engineered allogeneic T cells, we use TALEN to inactivate the CD52 gene in donor T cells and an anti-CD52 monoclonal antibody
to deplete CD52 expressing T cells in patients while sparing the therapeutic allogeneic T cells. We believe this enables a window of persistence for the
infused allogeneic T cells to actively target and destroy cancer cells. We are also developing ALLO-647, our own anti-CD52 monoclonal antibody, which is
designed to be used prior to infusing our other product candidates as part of a lymphodepletion regimen. Our off-the-shelf approach is dependent on state-
of-the-art manufacturing processes, and we are building a technical operations organization with fully integrated in-house expertise in clinical and
commercial engineered T cell manufacturing. In February 2019, we entered into a lease to build our own cell therapy manufacturing facility in Newark,
California, and we expect to commence current good manufacturing practices (cGMP) manufacturing at our facility in 2021. Finally, we plan to leverage
next generation technologies to develop more potent product candidates and to develop product candidates from a renewable cell source. We believe next
generation technologies will also allow us to develop allogeneic T cell therapies for the treatment of solid tumors, which to date have been difficult to treat
because of the lack of validated targets and tumor microenvironments that can impair the activity of T cells.

Our Pipeline

We are currently developing a pipeline of multiple allogeneic CAR T cell product candidates utilizing protein engineering, gene editing, gene

insertion and advanced proprietary T cell manufacturing technologies. Our most advanced product candidates, ALLO-501 and ALLO-501A, are engineered
allogeneic CAR T cell therapies that target CD19, a protein expressed on the cell surface of B cells and a validated target for B cell driven hematological
malignancies. We are also developing engineered allogeneic CAR T cell product candidates for multiple myeloma, clear cell renal cell carcinoma (ccRCC),
and other blood cancers and solid tumors. Our pipeline is represented in the diagram below.

Our lead product candidates include:

•

•

ALLO-501. We are sponsoring a Phase 1 clinical trial (the ALPHA trial) of ALLO-501 in patients with the most common R/R non-Hodgkin
lymphoma (NHL) subtypes. This includes R/R large B-cell lymphoma and R/R follicular lymphoma (FL). In May 2020, initial results from the
ALPHA trial were presented at the American Society of Clinical Oncology (ASCO) annual meeting. See “—Product Pipeline and Development
Strategy—Anti-CD19 Development Program—Initial Phase 1 Results from the ALPHA Trial” for information regarding the initial data results.
We are continuing the ALPHA trial to further explore ALLO-501 and lymphodepletion dose and schedule. We plan to report updated clinical data
from the ALPHA trial in the second quarter of 2021.

ALLO-501A. We have removed rituximab recognition domains in our second-generation version of ALLO-501, known as ALLO-501A, which we
believe will potentially facilitate treatment of more patients, as rituximab is a typical part of a treatment regimen for a patient with NHL. We
initiated a Phase 1/2 clinical trial for ALLO-501A (the ALPHA2 trial) in the second quarter of 2020. The Phase 1 portion of the ALPHA2 trial is
designed to assess the safety and tolerability at increasing dose levels of ALLO-501A in patients with R/R large B-cell lymphoma or transformed
FL. We plan to report initial clinical data from the ALPHA2 trial in the second quarter of 2021. Subject to data, we plan to proceed to the Phase 2
portion of the trial by the end of 2021.

ALLO-715. We are sponsoring a Phase 1 clinical trial (the UNIVERSAL trial) of ALLO-715, an allogeneic CAR T cell product candidate
targeting B-cell maturation antigen (BCMA), in adult patients with R/R multiple myeloma. In December 2020, initial results from the
UNIVERSAL trial were presented at the American Society of Hematology (ASH) annual meeting. See “—Product Pipeline and Development
Strategy—Anti-BCMA Development Program—Initial Phase 1 Results from the UNIVERSAL Trial” for information regarding the initial data
results. We are continuing the UNIVERSAL trial to further explore ALLO-715 and lymphodepletion dose and schedule. We plan to report updated
clinical data from the UNIVERSAL trial in the fourth quarter of 2021.

ALLO-715 plus nirogacestat. We recently initiated an expansion of the UNIVERSAL trial to assess ALLO-715 in combination with SpringWorks
Therapeutics, Inc.’s investigational gamma secretase inhibitor, nirogacestat. We believe nirogacestat has the potential to increase the cell surface
density of BCMA and reduce levels of soluble BCMA, thereby enhancing the activity of ALLO-715.

•

ALLO-605. We are advancing ALLO-605, an allogeneic CAR T cell product candidate targeting BCMA and our first product candidate to
incorporate our TurboCAR technology, for multiple myeloma. TurboCAR technology allows cytokine signaling to be engineered selectively into
CAR T cells and has shown the ability to improve the potency and persistence of the cells and to prevent and delay exhaustion of the cells in
preclinical models. We expect to submit an investigational new drug application (IND) in the first half of 2021 to initiate a Phase 1 clinical trial of
ALLO-605.

ALLO-316. Following the clearance of an IND in December 2020, we plan to initiate a Phase 1 clinical trial (the TRAVERSE trial) of ALLO-316,
an allogeneic CAR T cell product candidate targeting CD70, in adult patients with advanced or metastatic ccRCC in the first quarter of 2021. We
also plan to investigate the use of ALLO-316 for a second indication in R/R acute myeloid leukemia (AML).

ALLO-647. We are developing an anti-CD52 monoclonal antibody, ALLO-647, which is a component of our lymphodepletion regimen. ALLO-
647 may be able to reduce the likelihood of a patient’s immune system rejecting the engineered allogeneic T cells for a sufficient period of time to
enable a window of persistence during which our engineered allogeneic T cells can actively target and destroy cancer cells. We are currently
utilizing ALLO-647 in all of our clinical trials.

Our History and Team

We believe we have established a leadership position in allogeneic T cell therapy. In April 2018, we acquired certain assets from Pfizer Inc.

(Pfizer), including strategic license and collaboration agreements and other intellectual property related to the development and administration of allogeneic
CAR T cells for the treatment of cancer. We have an exclusive collaboration with Servier to develop and commercialize ALLO-501 and ALLO-501A, and
we hold the commercial rights to these product candidates in the United States. We also have an exclusive worldwide license from Cellectis to its TALEN
gene-editing technology for the development of allogeneic T cell product candidates directed against 15 different cancer antigens. Our collaboration with
Servier is intended to give us access to TALEN gene-editing technology for all product candidates we are co-developing. In connection with the Pfizer
asset acquisition, we hired a team of employees from Pfizer, who are primarily research and technical operation employees and were leading the research
and development of our product candidates and next generation gene engineering and cell engineering technologies at Pfizer.

Our world-class management team has significant experience in immuno-oncology and in progressing products from early stage research to
clinical trials, and ultimately to regulatory approval and commercialization. In particular, Dr. Belldegrun’s experience in T cell therapy dates back to his
time at the National Cancer Institute as a research fellow in surgical oncology and immunotherapy with Steven Rosenberg, M.D., Ph.D, a recognized
pioneer in immuno-oncology. Our President and Chief Executive Officer, Dr. Chang, served as Executive Vice President of Kite and held senior leadership
roles at Amgen, Inc. (Amgen). Moreover, both Dr. Belldegrun and Dr. Chang led the development and approval of Yescarta at Kite. Additionally, our Chief
Technical Officer, Alison Moore, Ph.D., was previously Senior Vice President, Process Development at Amgen, where she led the development,
deployment and oversight of manufacturing for approximately 80 multi-modality assets. Dr. Moore has over 25 years of experience in biotechnology,
including in the immuno-oncology space leading process development of Amgen’s comprehensive bi-specific T cell engager production platform. In
September 2019, Rafael Amado, M.D., joined us as our Executive Vice President of Research and Development and Chief Medical Officer. Dr. Amado has
more than 15 years of biotechnology and pharmaceutical industry experience leading clinical and research teams, and he most recently served as President,
Research and Development, at Adaptimmune Therapeutics plc, a T cell therapy company, from August 2018 to August 2019, and as Chief Medical Officer
from March 2015.

Our Strategy

Our goal is to maintain and build upon our leadership position in allogeneic T cell therapy. We plan to rapidly develop and, if approved,

commercialize allogeneic T cell products for the treatment of cancer that can be delivered faster, more reliably and at greater scale than autologous T cell
therapies. We believe achieving this goal could result in allogeneic T cell therapy becoming a standard of care in cancer treatment and enable us to make
potentially curative therapies more readily accessible to more patients throughout the world. Key elements of our strategy include:

•

Capitalize on a validated target and our leadership in engineered allogeneic anti-CD19 CAR T cell product candidates. Autologous anti-CD19
CAR T cell therapies, such as Kymriah and Yescarta, have emerged as potentially curative therapies for B-cell lymphomas and leukemias. We
believe developing allogeneic CAR T cell product candidates targeting CD19 is the next frontier in delivering potentially curative therapies
against B-cell lymphomas and leukemias. We believe our efforts to advance ALLO-501A and, subject to our clinical data, proceed to the Phase 2

6

Table of Contents

portion of the ALPHA2 trial by the end of 2021 would give us a leadership advantage to obtain the potential first approval of an anti-CD19
allogeneic CAR T cell product candidate.

•

•

•

•

Expand our leadership position within hematologic indications. In addition to ALLO-501A, we plan to advance our near-term pipeline against
additional hematologic targets where there remains a high unmet need. For example, we have a three-part strategy to target BCMA for the
treatment of patients with R/R multiple myeloma. We believe BCMA is a promising target, as results from clinical trials of third-party autologous
CAR T cell therapeutic candidates targeting BCMA have produced encouraging data. The first part of our strategy is to continue to advance the
UNIVERSAL trial of ALLO-715, which is the first trial of an allogeneic CAR T therapy targeting BCMA. We plan to report updated data from
the UNIVERSAL trial in the fourth quarter of 2021. Second, we are utilizing the UNIVERSAL trial to assess ALLO-715 in combination with
nirogacestat. Third, we expect to submit an IND in the first half of 2021 to initiate a Phase 1 clinical trial of ALLO-605, our first TurboCAR
candidate. We also plan to develop additional allogeneic T cell product candidates targeting other antigens found on hematologic malignancies,
including ALLO-316 targeting CD70 and ALLO-819 targeting FLT3, each for the treatment of AML.

Build state-of-the-art gene engineering and cell manufacturing capabilities. Manufacturing allogeneic T cell product candidates involves a
series of complex and precise steps. We believe a critical component to our success will be to leverage and expand our proprietary manufacturing
know-how, expertise and capacity. In February 2019, we entered into a lease for approximately 118,000 square feet to develop a state-of-the-art
cell therapy manufacturing facility in Newark, California. We are phasing the build-out of the facility, and completed the build-out of the majority
of the facility at the end of 2020. We plan to initiate manufacturing under cGMP in 2021. We believe establishing our own fully integrated
manufacturing operations and infrastructure will allow us to improve the manufacturing process, limit our reliance on contract manufacturing
organizations (CMOs) and more rapidly advance product candidates.

Expand into solid tumor indications with high unmet need and leverage next generation technologies to advance our platform. We plan to
continue to advance the research and development of product candidates directed against a broad portfolio of solid tumor targets, including CD70
for the treatment of ccRCC and DLL3 for the treatment of small cell lung cancer and other aggressive neuroendocrine tumors. We also plan to
leverage next generation technologies to make more potent allogeneic CAR T cells and improve the characteristics of our product candidates. For
example, we expect to advance a TurboCAR product candidate, ALLO-605, to the clinic this year and we are also advancing modified next-
generation TurboCARs to overcome some of the challenges of the solid tumor microenvironment. In addition, we are investigating next-
generation technologies to overcome rejection of allogeneic CAR T cells by the patient immune system and to increase specificity of CAR T
activity to avoid potential normal tissue toxicities associated with certain solid tumor targets. In collaboration with Notch Therapeutics Inc.
(Notch), we are researching and developing a process for production of product candidates derived from induced pluripotent stem cells (iPSCs).
We believe iPSCs may provide renewable starting material for our allogeneic CAR T cell product candidates that could allow for improved
efficiency of gene editing, greater scalability of supply, product homogeneity and more streamlined manufacturing. In addition, we continually
survey the scientific and industry landscape for opportunities to license, partner or acquire technologies that may help us advance current or new
cell therapies for the benefit of patients.

Accelerate the development of our product candidates across geographies. We are positioning ourselves to pursue clinical development of our
product candidates in additional markets around the world. Subject to our clinical progress in the United States, we plan to initiate clinical trials in
the European Union and United Kingdom. In addition, in December 2020, we jointly formed Allogene Overland Biopharm (CY) Limited for the
development, manufacturing and commercialization of certain of our product candidates targeting BCMA, CD70, FLT3, and DLL3 in China,
Taiwan, South Korea and Singapore. We plan to support the operations of this joint venture as it advances and we may selectively partner with
other third parties to develop and commercialize our product candidates in additional countries.

Allogeneic T Cell Therapy

The Immune System and Cancer

White blood cells are a component of the immune system and are responsible for defending the body against infectious pathogens and other
foreign material. T cells are a type of white blood cell and are involved in both sensing and killing infected or abnormal cells, including cancer cells, as
well as coordinating the activation of other cells in an immune response.

7

Table of Contents

T cells can be distinguished from other white blood cells by T cell receptors present on their cell surface. These receptors contribute to tumor

surveillance by directing T cells to recognize and destroy cancerous cells. When T cells with cancer-specific receptors are absent, present in low numbers,
of poor quality or rendered inactive by suppressive mechanisms, cancer may grow and spread. In addition, standard of care treatments, such as
chemotherapy regimens, as well as disease specific factors can damage the patient’s immune system, thereby inhibiting the ability of T cells to kill cancer.

Engineered T Cell Therapies

Engineered T cell therapy is a type of immunotherapy treatment whereby human T cells are removed from the body and engineered to express

CARs which, when infused into a patient, may allow the recognition and destruction of cancer cells in a targeted manner.

Chimeric Antigen Receptors (CARs)

CARs are engineered molecules that, when present on the surface of a T cell, enable the T cell to recognize specific proteins or antigens that are

present on the surface of other cells. The CAR in our product candidates is comprised of a single chain protein that contains the following elements:

•

•

•

Target Binding Domain: At one end of the CAR is a target binding domain that is specific to a target antigen. This domain extends out onto the
surface of the engineered T cell, where it can recognize the target antigens. The target binding domain consists of a single-chain variable fragment
(scFv) of an antibody comprising variable domains of heavy and light chains joined by a short linker.

Transmembrane Domain and Hinge: This middle portion of the CAR links the scFv target binding domain to the activating elements inside the
cell. This transmembrane domain “anchors” the CAR in the cell’s membrane. In addition, the transmembrane domain may also interact with other
transmembrane proteins that enhance CAR function. The hinge domain, which extends to the exterior of the cell, connects the transmembrane
domain to scFv and provides structural flexibility to facilitate optimal binding of scFv to the target antigen on the cancer cell’s surface.

Activating Domains: The other end of transmembrane domain, inside the T cell, is connected to two contiguous domains responsible for activating
the T cell when the CAR binds to the target cell. The CD3 zeta domain delivers an essential primary signal within the T cell, and the 41BB
domain delivers an additional, co-stimulatory signal. Together, these signals trigger T cell activation, resulting in proliferation of the CAR T cells
and killing of the cancer cell. In addition, activated CAR T cells stimulate the local secretion of cytokines and other molecules that can recruit and
activate additional immune cells to potentiate killing of the cancer cells.

In addition to the domains described above, ALLO-715 possesses two rituximab-recognition domains between the scFv and the hinge which

allow it to be recognized and eliminated by rituximab. ALLO-501 possesses rituximab recognition domains in a separate polypeptide termed RQR8 that is
co-expressed with the CAR. We have removed rituximab recognition domains in ALLO-501A, which we believe will potentially facilitate treatment of
more patients, as rituximab is a typical part of a treatment regimen for a patient with NHL.

The figure below shows the constructs that support our lead product candidates in clinical development: ALLO-501, ALLO-501A and ALLO-

715.

Allogeneic T Cell Therapies: The Next Revolution

There are two primary approaches to engineered T cell therapy: autologous and allogeneic. Autologous therapies use engineered T cells derived

from the individual patient, while allogeneic therapies use engineered T cells derived from unrelated healthy donors.

The autologous approach, pioneered by Novartis and Kite, has been highly successful in engineering patients’ immune systems to fight cancer,

in particular CD19 positive cancers, resulting in significant remission rates. Autologous products are manufactured by first collecting a patient’s white
blood cells, through a process known as leukapheresis, separating the T cells from the patient’s blood sample and proliferating the isolated T cells. After the
cells have multiplied, the CAR construct is virally transduced into the T cells and the engineered T cells are then propagated until a sufficient number of
cells are available for infusion into the patient. Finally, the engineered T cells are frozen, and then shipped back to the clinical center for administration to
the patient. The process from leukapheresis to delivery to the clinical center takes approximately two to four weeks.

While the autologous approach has been revolutionary, demonstrating compelling efficacy in many patients, it is burdened by the following key

limitations:

•

•

Lengthy Vein-to-Vein Time. Due to the individualized manufacturing process, patients must wait approximately two to four weeks to be treated
with their engineered cells. As a result, in the registrational trials for Yescarta and Kymriah, up to 31% of intended patients ultimately did not
receive treatment primarily due to interval complications from the underlying disease during manufacturing or manufacturing failures. In addition,
certain patients being treated with autologous product candidates have required bridging therapy as they wait for the manufacture of their T cells.
Bridging therapy to control disease may increase some cumulative or synergistic toxicities for the patients.

Variable Potency. In many cases, patients have T cells that have been damaged or weakened due to prior chemotherapy or hematopoietic stem-cell
transplant. Compromised T cells may not proliferate well during manufacturing or may produce cells with insufficient potency that cannot be used
for patient treatment, resulting in manufacturing failures, or that can show poor expansion and activity in patients. In addition, the individualized
nature of autologous manufacturing, together with the variability in patients’ T cells, may lead to variable potency of manufactured T cells, and
this variability may cause unpredictable treatment outcomes.

• Manufacturing Failures. Autologous cell manufacturing sometimes encounters production failures. This can mean that a patient never receives

treatment, as additional patient starting material may not be available or the patient may no longer be eligible due to advanced disease.
Furthermore, retreatment can be difficult due to a limited supply of usable patient starting material.

• High Production Cost. The delivery of autologous T cell therapy is complicated due to the individualized nature of manufacturing, which allows
only one patient to be treated from each manufacturing run and requires dedicated infrastructure to maintain a strict chain of custody and chain of
identity of patient-by-patient material collection, manufacturing and delivery. The complex logistics add significant cost to the process and limit
the ability to scale.

9

Table of Contents

Additionally, the collection of T cells through leukapheresis from each individual patient results in a time consuming and costly step in the
autologous process. In part due to these logistics, autologous treatment is currently only available at select centers.

Allogeneic engineered T cells are manufactured in a similar manner as autologous, but our manufacturing has two key differences: (1) our

allogeneic T cells are derived from healthy donors, not cancer patients, and (2) our allogeneic T cells are genetically engineered to minimize the risk of
GvHD and enable a window of persistence in the patient.

Our approach is designed to provide the same intended curative outcome as autologous therapy, while offering the following potential key

advantages:

•

•

•

•

Availability and Access. Starting with T cells from a healthy donor, we believe that at scale we can manufacture approximately 100 doses of
allogeneic product that could be used in any eligible patient. Because our allogeneic product candidates are designed to be frozen and available
off-the-shelf, they could potentially be readily shipped and administered to patients. We believe having an inventory of off-the-shelf allogeneic T
cell products can also facilitate delivering multiple product doses to a patient over time.

Speed to Patient. Many patients with aggressive cancer or rapidly progressing cancer that is refractory to existing therapies may not have multiple
weeks to wait for autologous T cell treatment. Our allogeneic approach has the potential to create off-the-shelf product inventory, which could
enable dosing of patients within days of a decision to treat. This would represent a significant reduction in patient wait time, potentially obviating
the need for any bridging therapy and allowing the treatment of patients who are too sick to wait for the autologous therapy, and could improve
patient outcomes.

Enhanced Cell Consistency and Potency. Our manufacturing process produces therapies from selected, screened and tested healthy donors.
Healthy donor T cells are potentially superior for engineered cellular therapy as compared to T cells from patients who have undergone prior
chemotherapy or hematopoietic stem-cell transplant, which can damage or weaken T cells. In addition, greater consistency of the product may
yield more predictable treatment outcomes.

Streamlined Manufacturing and Cost Efficiencies. We are building an efficient and scalable manufacturing process and organization. The
allogeneic approach utilizes healthy donor T cells which we believe provides enhanced scalability, reduces costs of engineered T cell therapy and
reduces costs to the healthcare system as our allogeneic approach does not require us to collect and track T cells from each individual patient.

Manufacturing Allogeneic T Cells

There are similarities as well as key differences between the processes for allogeneic and autologous T cell manufacturing, as illustrated in the

figure below.

The three primary steps to creating our engineered allogeneic CAR T cells are: (1) collection and transduction, (2) gene editing, and (3)

purification, formulation, and storage.

Step 1. Collection and Transduction

The starting material for our allogeneic T cell products is white blood cells from a healthy donor, which are collected using a standard blood
bank procedure known as leukapheresis. The collected cells are then screened, tested, and shipped to a central processing facility, where the T cells are
isolated and stored frozen, creating an inventory of starting healthy donor cells for manufacturing.

The manufacturing process starts by thawing frozen healthy donor T cells, which are then stimulated to proliferate and transduced with a viral

vector to integrate the CAR sequence into the T cell genome. The CAR sequence directs the expression of CAR proteins on the cell surface that allows the
transduced T cells to recognize and bind to a target molecule that is present on cancer cells.

We can concurrently add additional genes to these cells that confer specific properties. For example, we can add an off-switch by expressing
proteins that can make T cells susceptible to certain drugs, such as anti-CD20 monoclonal antibodies, and enable us to deplete our engineered T cells if
needed by administering such drugs to the patient. We can also introduce cytokine activation signaling within a CAR T cell that is designed to enhance the
proliferative potential, migratory behavior, and killing activity of cells. We are investigating multiple constructs designed to mimic cytokine signaling
selectively within CAR T cells, a technology platform that we call “TurboCARs”.

Step 2. Gene Editing

11

Table of Contents

Next, we use Cellectis’s electroporation and TALEN technologies for gene editing of T cells. TALENs are a class of DNA cutting enzymes

derived by fusing the DNA-cutting domain of a nuclease to the DNA-binding domains from transcription activator-like effectors (TALE). The TALE DNA-
binding domain can be tailored to specifically recognize a unique DNA sequence. These fusion proteins serve as readily targetable “DNA scissors” for
genome engineering applications that can enable targeted genome modifications.

Electroporation allows TALEN mRNA to enter into the cell, where it is translated into a nuclease that can cut DNA and inactivate specific target

genes. Inactivation of genes, such as TCRα and CD52, is intended to reduce the risk of GvHD and allow the allogeneic T cells to expand and persist in
patients. We believe the inactivation of other target genes using the TALEN technology can be incorporated into future product candidates, with the goal of
enhancing T cell function, including increasing potency against solid tumors.

The figure below illustrates how we utilize Cellectis’s TALEN and electroporation technology to inactivate the genes coding for TCRα and

CD52 in our allogeneic T cells for UCART19.

We believe the key benefits of TALEN technology are:

•

•

•

Precision. It is possible to design a TALEN that will cleave at any selected region in any gene, giving us the ability to achieve the desired genetic
outcome with any gene.

Specificity and Selectivity. TALEN may be designed to limit its DNA cleavage to the desired sequence and to reduce the risk of cutting elsewhere
in the genome. This parameter is essential, especially for therapeutic applications, because unwanted genomic modifications potentially could lead
to harmful effects for the patient. In addition, gene editing requires only a transient presence of TALEN, thus preserving the integrity and
functionality of the T cell’s genome.

Efficiency. A large percentage of cells treated by the nuclease bear the desired genomic modification after treatment is completed. We believe the
efficiency of TALEN editing helps to improve our manufacturing yields.

TCRα knockout: Non-modified allogeneic T cells bear functional TCRs and, if injected into a patient, can potentially recognize the patient’s
tissue as foreign and damage it. This reaction, known as GvHD, is mediated by intact TCRs on allogeneic T cells. To reduce the risk of GvHD, all of our
product candidates undergo the inactivation of a gene coding for TCRα, a key component of TCRs. The engineered T cells lacking functional TCRs are no
longer capable of recognizing peptide

12

Table of Contents

antigens presented on major histocompatibility complex proteins and thus incapable of attacking the patient’s normal tissue. This could mitigate the risk of
GvHD that can occur when allogeneic TCR-positive T cells are infused into patients who are unrelated to the healthy donor, as shown in the figure below.

CD52 knockout: The patient’s immune system is expected to recognize allogeneic T cells as foreign and destroy or reject them. To delay this
rejection, we use anti-CD52 antibody to deplete lymphocytes, including T cells, in patients. Anti-CD52 antibody recognizes CD52 protein expressed on
many immune cells, including T cells. CD52 protein is expressed in both donor and patient immune cells. To selectively deplete a patient’s immune cells
while sparing the therapeutic allogeneic T cells, we use TALEN gene editing to inactivate the CD52 gene in allogeneic T cells, thus protecting allogeneic T
cells from the anti-CD52 antibody mediated depletion.

By administering anti-CD52 antibody prior to infusing our product candidates, we believe we can reduce the likelihood of a patient’s immune

system rejecting the engineered allogeneic T cells for a sufficient period of time to enable a window of persistence during which our engineered allogeneic
T cells can expand and actively target and destroy cancer cells. We also believe our approach is unique and differentiated. To capitalize on this
differentiation and to secure our own source of anti-CD52 monoclonal antibody, we are developing ALLO-647. We are currently utilizing ALLO-647 in all
of our clinical trials.

Step 3. Purification, Formulation, and Storage

Once the allogeneic T cells have been engineered with CARs and gene edited to remove the genes encoding TCRα and CD52, they are cultured
for several days to increase the cell number and then harvested. The allogeneic cells then undergo a purification step to remove residual TCR positive cells
that have not undergone TCRα gene editing. We believe this purification step is essential as none of the currently available gene-editing nucleases is 100%
efficient at inactivating the target genes. After overnight recovery, the cells are formulated in a cryopreservation media and filled into closed, stoppered
vials prior to controlled-rate freezing and long-term storage in the vapor phase of liquid nitrogen. This inventory is securely stored and then shipped to
oncology centers as needed.

The figure below illustrates the steps in a manufacturing run for our engineered allogeneic CAR T product candidates.

Product Pipeline and Development Strategy

Using our proprietary allogeneic T cell platform, we are researching and developing multiple product candidates for the treatment of blood

cancers and solid tumors. Our product candidates are allogeneic T cells engineered to be used as off-the-shelf treatments for any patient with a particular
cancer type. Each product candidate targets a selected antigen expressed on tumor cells and bears specific engineered attributes.

Our product pipeline is represented in the diagram below:

In addition to our development of allogeneic CAR T cell product candidates, we are developing an anti-CD52 monoclonal antibody, ALLO-647,
which is designed to be used prior to infusing our other product candidates as part of the lymphodepletion regimen. As illustrated below, we believe ALLO-
647 can reduce the likelihood of a patient’s immune system from rejecting the engineered allogeneic T cells for a sufficient period of time to enable a
window of persistence during which our engineered allogeneic T cells can actively target and destroy cancer cells.

Anti-CD19 Development Program

CD19 is an antigen expressed on the surface of B cells, including on B cells that are malignant. B cells are considered non-essential tissue, as

they are not required for patient survival. We believe CD19 is a validated target for the treatment of B cell leukemias and lymphomas. Multiple autologous
anti-CD19 targeted CAR T therapies have shown promising results and have been approved by the FDA as therapies for adults with R/R large B-cell
lymphoma, adults with R/R mantle cell lymphoma, and for children and young adults with ALL that is refractory or has relapsed at least twice.

Our first anti-CD19 product candidate, UCART19, was advanced with our partner, Servier, who led manufacturing and clinical development.

UCART19 was manufactured to express a CAR that is designed to target CD19 and gene edited to lack TCRα and CD52 to minimize the risk of GvHD and
enable a window of persistence in the patient. In addition, UCART19 cells were engineered to express a small protein on the cell surface called RQR8,
which consists of two rituximab recognition domains. This allowed for recognition and elimination of cells in the event that silencing of CAR T cell
activity is desired.

Servier sponsored two Phase 1 clinical trials of UCART19 in patients with R/R CD19 positive B-cell ALL, one for adult patients (the CALM
trial) and one for pediatric patients (the PALL trial). The Servier-sponsored trials completed in 2020 and Servier determined that no new patients will be
enrolled. All patients from both studies will continue the long-term follow-up as planned. We and Servier are reviewing our development strategy for ALL.

ALLO-501 and ALLO-501A are our other allogeneic CAR T cell product candidates targeting CD19, which are jointly developed by us and
Servier. We are responsible for the manufacture of ALLO-501 and ALLO-501A. We also lead the clinical development program and are sponsoring the
ALPHA trial of ALLO-501 and ALPHA2 trial of ALLO-501A, each for patients with R/R NHL.

ALLO-501 is identical to UCART19 in molecular design, however several modifications have been introduced by us to the manufacturing

process for ALLO-501. These modifications are designed to facilitate more efficient manufacturing scale-up for the larger patient population targeted by
ALLO-501. Like UCART19, ALLO-501 also co-expresses a small protein on the cell surface called RQR8, which consists of two rituximab recognition
domains. This allows for destruction of the CAR T by rituximab.

Prior treatment with rituximab is typical for patients with NHL and, depending on the lag time between the rituximab administration and

planned ALLO-501 infusion, prior administration of rituximab may interfere with ALLO-501. As a result, we have removed RQR8 in the next generation
of ALLO-501, known as ALLO-501A. We believe ALLO-501A will have the potential to facilitate treatment of patients who were recently treated with
rituximab. ALLO-501A has been manufactured from several donors under non-cGMP conditions and has been compared to the current version of ALLO-
501 in vitro. In this study, we found that ALLO-501 and ALLO-501A exhibited similar characteristics and killing activity.

Lead Target Indications

Non-Hodgkin Lymphoma (NHL)

15

Table of Contents

NHL is a hematologic cancer originating from malignant lymphocytes. It is the most common hematological malignancy in the United States,
with 81,560 new cases estimated to be diagnosed and 20,720 deaths estimated in 2021, according to the American Cancer Society. Over 60 NHL subtypes
have been identified, and each subtype represents different neoplastic lymphoid cells (T, B or NK cells) that have arrested at different stages of
differentiation. The most common subtype is B-cell, which represented over 90% of all new NHL cases in 2016.

B-cell NHL itself represents a group of different neoplasms that not only differ in pathology, but also response to therapy and prognosis. NHL

can be rapidly growing (aggressive) with short survival, such as large B-cell lymphomas, which include diffuse large B cell lymphoma (DLBCL), or it can
be slow growing, or indolent, such as FL. Despite recent therapeutic advances, more than 50% of patients with aggressive B-cell NHL are incurable using
existing approved therapies.

The R-CHOP chemotherapy combination (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) introduced in the early

2000s remains the standard of care for newly diagnosed DLBCL, and five-year survival can be achieved for 55-60% of patients. Unfortunately,
approximately 30% of DLBCL require second-line therapy, and subsequent therapy is dependent on whether the patients are candidates for high-dose
therapy followed by autologous stem-cell therapy. A retrospective analysis of patients with R/R DLBCL, who were not treated with autologous CAR T
therapy, found that outcomes in this population are poor, with an objective response rate of 26% (CR: 7%, partial response: 18%) and median overall
survival of 6.3 months.

Despite availability of multiple active agents, high response rates, and long progression-free survival with first-line therapy, FL remains an

incurable disease. Most patients treated today eventually relapse, and subsequent responses and durations of responses become increasingly shorter.
Ultimately, patients become resistant to chemo-immunotherapy, clinically defined as relapsed within 12 months. In these patients, the toxicity commonly
outweighs the benefit of treatment with chemotherapy. Therefore, there remains a high unmet medical need for newer treatment options, especially for
those patients with cancer that is resistant to chemo-immunotherapy.

Acute Lymphoblastic Leukemia (ALL)

ALL is characterized by the proliferation of immature lymphocytes in the bone marrow. Approximately 5,690 new cases and 1,580 deaths in the

United States are estimated in 2021, according to the American Cancer Society. Approximately 80% of cases of ALL are B-cell ALL.

The risk for developing ALL is highest in children younger than five years of age. From age five until the mid-20s, the risk declines slowly and
begins to steadily rise again after age 50. Overall, about 40% of all cases of ALL are in adults. Though most cases occur in children, approximately 80% of
deaths from ALL occur in adults.

Over the past four decades pediatric cure rates have reached greater than 80% in developed countries. This progress can be attributed, in part, to
a deeper understanding of the molecular genetics and pathogenesis of the disease, advances in combination chemotherapy, monitoring of minimal residual
disease, use of tyrosine kinase inhibitors for Philadelphia chromosome–positive ALL and the success of autologous CAR T cell therapies. Allogeneic stem-
cell transplant (allo-SCT) offers the potential for cure in some individuals, however, the option is available only to approximately a third of patients due to
the lack of compatible stem cell source, general health, or the high risk of complications. Furthermore, allo-SCT carries a high rate of treatment-related
mortality which can occur in approximately 20-30% of patients undergoing allo-SCT. In patients with R/R ALL after two or more lines of therapy, the
median disease-free survival is less than six months. The five-year overall survival in adults over the age of 60 is approximately 20%, highlighting the high
unmet need despite the recent advances in the treatment of ALL.

Initial Phase 1 Results from the ALPHA Trial

In May 2020, in collaboration with Servier, we announced initial results from the ALPHA trial in R/R NHL at the ASCO annual meeting.

The ALPHA trial is a dose-escalation study for ALLO-501 with three separate dose cohorts, from 40 × 10  to 360 × 10  total cells. Prior to ALLO-
501 treatment, all patients undergo lymphodepletion with a regimen of fludarabine, cyclophosphamide and a low dose or higher dose ALLO-647. As of the
May 11, 2020 data cutoff, 23 patients were enrolled and 22 patients received ALLO-501. One patient was removed from the study prior to lymphodepletion
due to acute renal failure from urinary obstruction. The median time from enrollment to the start of therapy was five days.

For the efficacy analysis, 19 out of 22 patients reached at least one month assessment as of the May 2020 data cutoff. Responses were observed

across all cell doses and tumor histologies (DLBCL and FL) with an overall response rate (ORR) of 63% and complete response (CR) rate of 37%. Higher
dose ALLO-647 was associated with a higher CR rate of 50%, deeper lymphodepletion and delayed host T cell recovery. With a median follow-up of 3.8
months, nine of the 12 responding patients (75%) remained in response as of the data cutoff.

Four patients (18%) experienced serious adverse events (SAEs). An SAE is defined as any untoward medical occurrence at any dose that (i)
results in death; (ii) is life-threatening (immediate risk of death); (iii) requires inpatient hospitalization or prolongation of existing hospitalization; (iv)
results in persistent or significant disability/incapacity (substantial disruption of the ability to conduct normal life functions); (v) results in congenital
anomaly/birth defect; or (vi) is considered to be an important medical event. One patient had Grade 2 pyrexia and Grade 2 cytomegalovirus (CMV)
reactivation which resolved in two days and six days, respectively. One patient had Grade 3 rotavirus infection and Grade 3 hypokalemia which resolved in
15 days and two days, respectively. One patient had Grade 3 febrile neutropenia and Grade 3 hypotension which each resolved in two days. One patient had
a Grade 3 upper GI hemorrhage which resolved in one day and Grade 3 CMV reactivation which resolved in 25 days.

Adverse events were observed across all dose levels of ALLO-501 and ALLO-647. SAEs were observed at ALLO-501 cell dose level 40 x 10

and 120 x 10  and at both dose levels of ALLO-647.

Clinical Development Plan

The ALPHA trial is an open-label, Phase 1, single arm, multicenter clinical trial evaluating the safety and tolerability of ALLO-501 in adult

patients with R/R large B-cell lymphoma, including DLBCL, or FL. Cell kinetics and pharmacodynamics of ALLO-501 will be evaluated as secondary and
exploratory objectives, respectively. We are exploring the optimal dose and schedule of ALLO-501 and the lymphodepletion regimen in additional cohorts,
which includes a cohort of patients receiving a consolidation of ALLO-501 doses. The consolidation consists of two infusions of 120 million CAR T cells,
with a first infusion following the lymphodepletion regimen of fludarabine, cyclophosphamide and ALLO-647 and an initial tumor assessment performed
at day 28. If a patient is in complete response, partial response or stable disease at day 28, a second infusion is given approximately five to six weeks after
the first infusion. Prior to the second cell infusion, a patient will be eligible to receive a modified lymphodepletion consisting only of ALLO-647. We
expect to report updated data from the ALPHA trial in the second quarter of 2021.

In the second quarter of 2020, we initiated ALPHA2, which is an open-label, Phase 1/2, single arm, multicenter clinical trial evaluating the

safety and efficacy of ALLO-501A in adult patients with R/R large B-cell lymphoma, including DLBCL, or transformed FL. Cell kinetics and
pharmacodynamics of ALLO-501A will be evaluated as secondary and exploratory objectives, respectively. The Phase 1 portion of the ALPHA2 trial is
designed to assess the safety and tolerability at increasing dose levels of ALLO-501A and consolidation of ALLO-501A dosing, in order to identify the
recommended doses and schedule of ALLO-501A and the lymphodepletion regimen for use in the Phase 2 portion of the trial. We expect to report initial
data from the ALPHA2 trial in the second quarter of 2021. Subject to the data as well as follow-up data from ALPHA and ALPHA2 expected in the second
half of 2021, we plan to proceed to the Phase 2 portion of the trial in adult patients with R/R large B-cell lymphoma, including DLBCL, or transformed FL
by the end of 2021.

All patients treated with ALLO-501 and ALLO-501A will be followed in a long-term follow-up study.

Anti-BCMA Development Program

BCMA is a member of the tumor necrosis factor receptor family and is selectively expressed on immunoglobulin-producing plasma cells,

including malignant plasma cells (myeloma cells). We believe BCMA is an appropriate target for the treatment of multiple myeloma. Two autologous anti-
BCMA targeted CAR T therapies have shown promising results in clinical trials and the sponsors have submitted the therapies to the FDA for approval for
the treatment of adult patients with multiple myeloma who have received at least three prior therapies.

We are currently advancing a three-part strategy for the treatment of multiple myeloma. First, we are advancing ALLO-715, an anti-BCMA

allogeneic CAR T cell product candidate. ALLO-715 is manufactured to express a CAR that is designed to target BCMA and gene edited to lack TCRα and
CD52 to minimize the risk of GvHD and enable a window of persistence in the patient. In addition, rituximab recognition domains, as an off-switch, have
been incorporated in between the scFv and the linker domain.

Second, as part of the ongoing Phase 1 clinical trial (the UNIVERSAL trial) of ALLO-715 in adult patients with R/R multiple myeloma, we are
assessing the combination of ALLO-715 with SpringWorks Therapeutics, Inc.’s investigational gamma secretase inhibitor, nirogacestat. Gamma secretase
inhibition prevents the cleavage and shedding of BCMA from the surface of myeloma cells. In preclinical models, nirogacestat has been shown to increase
the cell surface density of BCMA and reduce levels of soluble BCMA, thereby enhancing the activity of BCMA-targeted therapies. In addition, emerging
clinical data suggest that a gamma secretase inhibitor may increase anti-tumor efficacy of BCMA-targeted autologous CAR T therapy in patients with R/R
multiple myeloma.

18

Table of Contents

Third, we are progressing our next-generation version of ALLO-715, known as ALLO-605, that incorporates our TurboCAR technology to

allow cytokine signaling to be engineered selectively into CAR T cells. TurboCARs have shown the ability to improve the potency and persistence of the
CAR T cells and to prevent and delay exhaustion of the CAR T cells in preclinical models. ALLO-605 uses a constitutive cytokine signaling domain and a
rituximab-mediated off-switch, as illustrated below. We expect to submit an IND in the first half of 2021 to initiate a Phase 1 clinical trial of ALLO-605.

Target Indication: Multiple Myeloma

Multiple myeloma is a hematological malignancy that is characterized by uncontrolled expansion of bone marrow plasma cells. There will be an

estimated 34,920 new cases of multiple myeloma and 12,410 deaths from multiple myeloma in 2021 in the United States according to the American Cancer
Society. Multiple myeloma predominantly affects the elderly, with 14 times more patients diagnosed at age 65 and over than those diagnosed under the age
of 65.

For patients less than age of 70 with no comorbidities, autologous stem cell therapy is the preferred option to provide a durable response. For

transplant ineligible patients, immunomodulatory drugs (Revlimid, Pomalyst, Thalomid) and proteasome inhibitors (Velcade, Kyrprolis, Ninlaro), often
used in combination with one another, have displaced older cytotoxic agents as the mainstay of treatment. More recently, several new drugs with novel
mechanisms (Darzalex, Empliciti, Farydak, Xpovio) have been approved for multiple myeloma, however none of these novel treatments is considered as
curative.

Despite the introduction of newer therapies, a majority of patients are expected to relapse and the unmet need in patients with R/R myeloma

remains high. In clinical trials, only 3% of patients who were previously treated with at least three lines of therapy (including proteasome inhibitors and
immunomodulatory drugs), or who were refractory to both proteasome inhibitors and immunomodulatory drugs, achieved a CR to Darzalex, a CD38-
directed monoclonal antibody. Median survival in such patients was just 17.5 months. Trials of autologous CAR T cell therapies have shown significant
promise in multiple myeloma with reported CR rates that are substantially higher.

Initial Phase 1 Results from the UNIVERSAL Trial

In December 2020, we announced initial results from the UNIVERSAL trial in R/R multiple myeloma at the ASH annual meeting.

As of the October 30, 2020 data cutoff, 35 patients were enrolled with 31 patients evaluable for safety and 26 patients evaluable for efficacy.

Patients were refractory to their last line of myeloma therapy, had a median of five prior lines of therapy, and 94% were penta-exposed, which means the
patient had previously received at least one CD38 monoclonal antibody, two proteosome inhibitors and two immunomodulatory drugs. Four patients
became ineligible for treatment due to rapidly progressing disease. The median time from enrollment to the start of therapy was five days.

19

Table of Contents

In the initial dose escalation phase of the UNIVERSAL trial, patients received lymphodepletion followed by ALLO-715 at one of three dose levels

(DL1 = 40M cells, DL2 = 160M cells, DL3 = 320M cells) in a 3+3 dose escalation design. DL4 (480M cells) was added in a subsequent cohort. Two
lymphodepletion regimens were evaluated, with the trial enrollment primarily focused on the FCA lymphodepletion regimen:

•
•

FCA: Fludarabine 90 mg/m , Cyclophosphamide 900 mg/m , and ALLO-647 from 39 to 90mg divided over three days; and
CA: Cyclophosphamide 900 mg/m  and ALLO-647 39mg divided over three days.

Higher CAR T cell doses were associated with an increased response rate and greater cell expansion. In the DL3 cohort (320M CAR T+ cells), the

ORR was 60% with 40% of patients achieving a very good partial response (VGPR) or better (VGPR+). VGPR+ is defined as a stringent complete
response, complete response or VGPR. Across all cohorts and lymphodepletion regimens, six patients achieved VGPR+, five of whom were in the FCA
lymphodepletion regimen. Minimal residual disease (MRD) assessment was completed in five of the six patients with a VGPR+ response and all achieved
an MRD negative status. MRD negative status occurs when a patient achieves a CR and there is no evidence of tumor cells in the marrow when using
sensitive tests such as polymerase chain reaction or flow cytometry.

As of the data cutoff, the overall median follow-up for efficacy was 3.2 months and six out of the nine patients treated with DL3 or DL4 with a

response remain in response. The longest response was ongoing at six months from the DL3 cohort with FCA lymphodepletion.

The UNIVERSAL trial is an open-label, Phase 1, single arm, multicenter clinical trial evaluating the safety and tolerability of ALLO-715 in

adult patients with R/R multiple myeloma. The safety of ALLO-647, cell kinetics, pharmacodynamics, and efficacy will be evaluated as secondary
objectives. We are exploring the optimal dose and schedule of

20

Table of Contents

ALLO-715 and the lymphodepletion regimen. We expect to report updated data from the UNIVERSAL trial in the fourth quarter of 2021.

The UNIVERSAL trial recently initiated the evaluation of ALLO-715 in combination with nirogacestat. Prior to ALLO-715 and nirogacestat

treatment, all patients will undergo lymphodepletion with a regimen of fludarabine, cyclophosphamide and ALLO-647. The combination cohort will assess
the safety and tolerability of ALLO-715 in combination with nirogacestat. The preliminary anti-tumor activity of the combination, cell kinetics,
pharmacokinetics and host immune cell depletion/reconstitution will be evaluated as secondary objectives.

We expect to submit an IND in the first half of 2021 to initiate a Phase 1 clinical trial of our first TurboCAR candidate, ALLO-605, in adult
patients with R/R multiple myeloma. The ALLO-605 trial will assess the safety and tolerability of increasing doses of ALLO-605 along with its clinical
efficacy. The preliminary anti-tumor activity, cell kinetics, safety and tolerability of ALLO-647 in combination with fludarabine and cyclophosphamide,
and patient reported outcomes will be evaluated as secondary objectives.

Anti-CD70 Development Program

CD70 is an antigen selectively expressed on several types of cancer cells, including on approximately 80-100% of ccRCC cells and 95% of AML

cells, with limited off-tumor expression. CD70 is also expressed on a portion of DLBCL, multiple myeloma, chronic lymphocytic leukemia and
glioblastoma cells as well as on activated T cells. Accordingly, we believe progressing allogeneic CAR T cell therapies directed against CD70 could be
promising in solid tumor indications as well as hematological malignancies.

In December 2020, the FDA cleared an IND to initiate a Phase 1 clinical trial (the TRAVERSE trial) of ALLO-316 in adult patients with advanced

or metastatic ccRCC. We plan to initiate the TRAVERSE trial in the first quarter of 2021. We also plan to investigate the use of ALLO-316 for a second
indication in R/R AML. While CD70 can be expressed on activated T cells, ALLO-316 was associated with minimal or no fratricide in preclinical studies,
meaning that ALLO-316 cells did not mediate the targeted killing of other ALLO-316 cells.

ALLO-316 is manufactured to express a CAR that is designed to target CD70 and gene edited to lack TCRα and CD52 to minimize the risk of
GvHD and enable a window of persistence in the patient. In addition, rituximab and CD34 recognition domains have been incorporated in between the
scFv and the linker domain, as illustrated below. The rituximab recognition domains allow elimination of cells with rituximab in the event that silencing of
CAR T cell activity is desired. The CD34 domain confers recognition by an anti-CD34 antibody, and may be used as a surface marker to monitor ALLO-
316 in patients by flow cytometry.

Lead Target Indications:

Clear Cell Renal Cell Carcinoma

ccRCC is the most common subtype of renal cancer. Approximately 76,080 new cases of renal cell carcinoma are estimated to be diagnosed in

the United States and 13,780 deaths are estimated in 2021, according to the American Cancer Society. The five-year survival rate for patients with early-
stage disease is greater than 90% compared with less than 15% for those with advanced kidney cancer.

21

Table of Contents

Systemic therapy (including immunotherapy and molecularly targeted agents), surgery, and radiation therapy all may have a role in the
treatment paradigm depending on the extent of disease, sites of involvement, and patient-specific factors. While vascular endothelial growth factor
(VEGF)-directed therapies (e.g. sunitinib) represented a first-line standard for over a decade, these therapies have been quickly supplanted by combination
therapies incorporating PD-1 immune-checkpoint inhibition as the backbone.

The combination of VEGF and immune check-point inhibitors, such as axitinib and pembrolizumab, are often used in the first line setting and
has shown a median progression-free survival of 15.1 months with an ORR of 59.3% and CR rate of 5.8%. Patients who progress on immune checkpoint-
based combination therapies can be treated with cabozantinib, pazopanip, temsirolimus or high dose IL-2. There remains a need for novel, mechanistically
distinct therapies.

Acute Myeloid Leukemia

AML is a cancer of bone marrow stem cells and is the most common type of acute leukemia in adults. The American Cancer Society estimated

19,940 new diagnoses and 11,180 deaths in the United States in 2020. Although advances in supportive care and prognostic risk stratification have
optimized established therapies, overall long-term survival remains poor and AML is a high unmet medical need. Patients have a poor prognosis despite
improvements in chemotherapy regimens and supportive care.

AML is a biologically and clinically heterogenous disease. The identification of recurrent genetic mutations, such as FLT3-ITD, NMP1 and

CEBPA, has helped refine individual prognosis and guide management. Despite advances in supportive care, the backbone of therapy remains a
combination of cytarabine- and anthracycline-based regimens with allogeneic stem cell transplantation for the medically-fit patients. Twenty to 30 percent
of young adult patients and 50 percent of older adults with newly diagnosed AML will fail to attain a CR with intensive induction chemotherapy due to
drug resistance or death. In addition, a percentage of patients who initially attain a CR will relapse. Relapse after conventional chemotherapy remains a
major problem in patients with myeloid malignancies such as AML, and the major cause of death after diagnosis of AML is from relapsed disease. The
development of new treatments, in concert with improved genetic profiling and risk stratification, are greatly needed in the goal to achieve incremental
gains in remission and survival.

Clinical Development Plan

The TRAVERSE trial is an open-label, Phase 1, single arm, multicenter clinical trial evaluating the safety and tolerability of ALLO-316 in adult

patients with advanced or metastatic ccRCC. Anti-tumor activity, cell kinetics, pharmacodynamics, and correlation of outcome with tumor CD70
expression will be evaluated as secondary objectives. The trial is a dose-escalation study for ALLO-316 with four separate dose cohorts, from 40 × 10  to
480 × 10  total cells. Prior to ALLO-316 treatment, all patients will undergo lymphodepletion with a regimen of fludarabine, cyclophosphamide and
ALLO-647. We expect to initiate the TRAVERSE trial in the first quarter of 2021.

Future Opportunities

Moving forward, we plan to utilize our allogeneic platform to pursue additional targets of interest. These include the additional targets currently

in our pipeline as well as other targets that might be validated in the future. For example, we are developing allogeneic CAR T cell product candidates
targeting FLT3 for the treatment of AML (ALLO-819) and DLL3 for the treatment of small cell lung cancer (SCLC).

•

•

Acute Myeloid Leukemia and FLT3. FLT3 is a receptor tyrosine kinase that is overactive in AML blasts. We have conducted in vitro and in vivo
studies of our anti-FLT3 CAR T candidate, ALLO-819, that show anti-tumor activity against blasts present in bone marrow from AML patients
and in mice. We are currently testing increasing activity of our clinical candidate with the addition of a TurboCAR cytokine signaling domain
ahead of finalizing an IND-enabling data set.

Small Cell Lung Cancer and DLL3. DLL3 is a target which is being pursued for SCLC using antibody drug conjugates, bi-specifics and
autologous CAR T therapies. According to the American Cancer Society, approximately 235,760 new cases of lung cancer are expected to be
diagnosed in the United States in 2021 and SCLC comprises approximately 10-15% of all lung cancers. SCLC is responsive to chemotherapy, but
recurrence arises rapidly, with less than 7% of patients surviving over five years. SCLC has shown to be responsive to immunotherapy with
approximately one-third of patients responding to PD-1/PD-L1 therapy and achieving a median overall survival of approximately thirteen months
for patients who received PD-L1 and platinum-based chemotherapy. We believe an allogeneic anti-DLL3 CAR T cell product candidate could be
used alone or in combination with PD-1/PD-L1 therapy.

22

Table of Contents

We are currently testing and refining constructs for an anti-DLL3 CAR T candidate and investigating the use of TurboCARs and next generation
TurboCARs designed to overcome negative effects of the tumor microenvironment. Following completion of these studies, we plan to progress to
IND-enabling studies.

We also plan to investigate the potential to enhance our platform using next-generation technologies such as TurboCARs, renewable cell

sources, site-specific integration, multi-specific CARs and other technology related to enhancing specificity and avoiding immune rejection.

•

•

•

TurboCARs. Mimicking cytokine signaling within a CAR T cell could enhance the proliferative potential, migratory behavior, activation status
and killing activity of cells. Such modulation may enhance the anti-tumor activity and durability of CAR T cells without affecting non-engineered
immune cells. We believe TurboCARs may also allow for reduced CAR T cell dose requirements and greater impact in overcoming exhaustion in
solid tumor environments. We are investigating multiple constructs designed to mimic cytokine signaling selectively within CAR T cells, a
technology platform that we call “TurboCARs”. We are progressing our first TurboCAR, ALLO-605, which targets BCMA and uses a constitutive
cytokine signaling domain and a rituximab-mediated off-switch. We plan to submit an IND to initiate a Phase 1 clinical trial of ALLO-605 in the
first half of 2021.

Renewable Cell Source. In November 2019, we entered into a Collaboration and License Agreement with Notch (the Notch Collaboration
Agreement), pursuant to which Notch has granted to us an exclusive, worldwide, royalty-bearing, license to certain Notch intellectual property to
develop and commercialize gene-edited T cell and/or natural killer cell products from iPSCs directed at certain CAR targets for initial application
in NHL, ALL and multiple myeloma. We believe iPSCs may provide renewable starting material for our allogeneic CAR T cell product candidates
that could allow for improved efficiency of gene editing, greater scalability of supply, product homogeneity and more streamlined manufacturing.
We commenced the research collaboration with Notch in 2019.

Site-Specific Integration. Using a combination of gene-editing technology and homologous recombination technology we can potentially
integrate the CAR expressing DNA into specific target genes within the T cell DNA. Such site-specific integration may allow the CAR or other
transgenes to be introduced into T cells in a more homogeneous manner, allowing a more uniform and controlled expression of the proteins, with
the goal of generating CAR T cell products that behave in a more consistent and predictable manner.

• Multi-specific CARs. We are investigating the utility of a single cell product targeting multiple antigens. This may be accomplished by including
two antigen binding domains with different specificity in a single polypeptide encoding the CAR or in two separate polypeptides each encoding a
CAR with different antigen specificity.

•

Increasing tumor specificity of targets: We are investigating technology to localize activity of an allogeneic CAR T cell to the tumor
microenvironment in an effort to extend specificity and therefore safety of CAR T cells. We believe this approach may be particularly promising
for solid tumor targets that are associated with normal tissue toxicities.

• Next-generation anti-rejection technology: We are investigating additional ways, beyond our existing anti-CD52 antibody technology, to prevent

patient immune rejection of our allogeneic CAR T cells. We are exploring ways to engineer allogeneic CAR T cells to escape detection from the
patient immune system. We are also exploring engineering allogeneic CAR T cells with mechanisms to attack certain patient immune cells that
would otherwise lead to rejection. For instance, we are exploring allo-immune defense receptor technology licensed from the Baylor College of
Medicine. This technology is designed to recognize and destroy allo-reactive host immune cells that would otherwise be capable of rejecting the
allogeneic CAR T cells, which could provide enhanced persistence of the allogeneic CAR T cells.

In addition, we continually survey the scientific and industry landscape for opportunities to license, partner or acquire technologies that may

help us advance current or new T cell therapies for the benefit of patients.

Our Manufacturing Strategy

We have invested resources to optimize our manufacturing process, including the development of improved analytical methods and
instrumentation. We plan to continue to invest in process science, product characterization and manufacturing to continuously improve our production and
supply chain capabilities over time.

23

Table of Contents

Our product candidates are designed and manufactured via a platform comprised of defined unit operations and technologies. The process is

gradually developed from small to larger scales, incorporating compliant procedures to create cGMP conditions. Although we have a platform-based
manufacturing model, each product is unique and for each new product candidate, a developmental phase is necessary to individually customize each
engineering step and to create a robust procedure that can later be implemented in a cGMP environment to ensure the production of clinical batches. This
work is performed in our research and development environment to evaluate and assess variability in each step of the process in order to define the most
reliable production conditions.

Our cell-based product candidates are currently manufactured in the United States by a CMO, and we manage all other aspects of the supply,

including planning, CMO oversight, disposition and distribution logistics. The CMO that is manufacturing our clinical supply is subject to cGMP
requirements, using qualified equipment and materials. We also utilize separate third party contractors to manufacture cGMP raw materials that are used for
the manufacturing of our product candidates, such as viral vectors that are used to deliver the applicable CAR gene into the T cells. We believe all materials
and components utilized in the production of the cell line, viral vector and final T cell product are available from qualified suppliers and suitable for pivotal
process development in readiness for registration and commercialization.

In addition, in February 2019, we entered into a lease for approximately 118,000 square feet to develop a state-of-the-art cell therapy
manufacturing facility in Newark, California. We are phasing the build-out of the facility, and completed the build-out of the majority of the facility at the
end of 2020. We expect to initiate cGMP manufacturing operations in 2021. However, we expect to continue to rely on our CMO and may rely on CMOs
and other third parties for the manufacturing and processing of our product candidates in the future. We also utilize a CMO in the United States for the
manufacture and supply of ALLO-647 and we plan to continue to rely on the CMO for future production of ALLO-647. We believe the use of contract
manufacturing and testing for our first clinical product candidates has allowed us to rapidly prepare for clinical trials in accordance with our development
plans. We expect third-party manufacturers will be capable of providing and processing sufficient quantities of our product candidates to meet anticipated
clinical trial demands.

We plan to create a robust supply chain with redundant sources of supply comprised of both internal and external infrastructure.

Strategic Agreements

On December 14, 2020, we entered into a License Agreement with Allogene Overland Biopharm (CY) Limited, a joint venture established by us

and Overland Pharmaceuticals (CY) Inc., pursuant to a Share Purchase Agreement, dated December 14, 2020, for the purpose of developing,
manufacturing and commercializing allogeneic CAR T cell therapies for patients in greater China, Taiwan, South Korea and Singapore.

We have also entered into multiple additional strategic agreements and collaborations, including an Asset Contribution Agreement with Pfizer (the

Pfizer Agreement), a License Agreement with Cellectis (the Cellectis Agreement), an Exclusive License and Collaboration Agreement with Servier (the
Servier Agreement), and the Notch Collaboration Agreement

For additional information regarding our significant agreements, see Note 7 to our consolidated financial statements appearing elsewhere in this

Annual Report.

Intellectual Property

Our commercial success depends in part on our ability to obtain and maintain proprietary protection for our product candidates, as well as novel
discoveries, product development technologies, and know-how. Our commercial success also depends in part on our ability to operate without infringing on
the proprietary rights of others and to prevent others from infringing our proprietary rights. Our policy is to develop and maintain protection of our
proprietary position by, among other methods, filing or in-licensing U.S. and foreign patents and applications related to our technology, inventions, and
improvements that are important to the development and implementation of our business.

We also rely on trademarks, trade secrets, know-how, continuing technological innovation, confidentiality agreements, and invention assignment

agreements to develop and maintain our proprietary position. The confidentiality agreements are designed to protect our proprietary information and the
invention assignment agreements are designed to grant us ownership of technologies that are developed for us by our employees, consultants, or other third
parties. We seek to preserve the integrity and confidentiality of our data and trade secrets by maintaining physical security of our premises and physical and
electronic security of our information technology systems. While we have confidence in our agreements and security measures, either may be breached,
and we may not have adequate remedies. In addition, our trade secrets may otherwise become known or independently discovered by competitors.

24

Table of Contents

With respect to both licensed and company-owned intellectual property, we cannot be sure that patents will be granted with respect to any of our

pending patent applications or with respect to any patent applications filed by us in the future, nor can we be sure that any of our existing patents or any
patents that may be granted to us in the future will be commercially useful in protecting our commercial products and methods of using and manufacturing
the same.

We are actively building our intellectual property portfolio around our product candidates and our discovery programs, based on our own

intellectual property as well as licensed intellectual property. Following the execution of the Pfizer Agreement, we are the owners of, co-owners of, or the
licensee of multiple patents and patent applications in the United States and worldwide. These licensed assets include rights to the Cellectis TALEN gene-
editing technology to engineer T cells that lack functional TCRs and to inactivate the CD52 gene in donor cells. We have exclusive worldwide rights to
these patents for certain antigen targets, including BCMA, CD70, FLT3 and DLL3, and have U.S. rights to these patents for CD19. We also have rights to a
Cellectis U.S. patent for technology covering an engineered T cell therapy combining CD52 gene knockout in combination with an anti-CD52 antibody for
certain products directed against certain antigen targets. Our patent rights are composed of patents and pending patent applications that are solely owned by
us, co-owned with Servier, co-owned with Cellectis, exclusively licensed from Pfizer, exclusively licensed from Servier, or exclusively licensed from
Cellectis.

Our patent portfolio includes protection for our lead product candidates, ALLO-501, ALLO-501A and ALLO-715, as well as our other

research-stage candidates. With respect to ALLO-501 and ALLO-501A, we have an exclusive license from Servier in the United States to patent rights
covering composition of matter and methods of making and use covering ALLO-501 and ALLO-501A. With respect to ALLO-715, we have an exclusive
license from Pfizer to patent rights covering ALLO-715 in the United States and in foreign jurisdictions. These rights include composition of matter
protection for ALLO-715 and methods of making and using ALLO-715. More generally, our patent portfolio and filing strategy is designed to provide
multiple layers of protection by pursuing claims directed toward: (1) antigen binding domains directed to the targets of our product candidates; (2) CAR
constructs used in our product candidates; (3) methods of treatment for therapeutic indications; (4) manufacturing processes, preconditioning methods, and
dosing regimens; and (5) reducing GvHD, and methods for genetically engineering immune cells suitable for allogeneic use.

The term of individual patents depends upon the legal term of the patents in the countries in which they are obtained. In most countries in which

we file, the patent term is 20 years from the date of filing of the first non-provisional application to which priority is claimed. In the United States, patent
term may be lengthened by patent term adjustment, which compensates a patentee for administrative delays by the United States Patent and Trademark
Office in granting a patent, or may be shortened if a patent is terminally disclaimed over an earlier-filed patent. In the United States, the term of a patent
that covers an FDA-approved drug may also be eligible for a patent term extension of up to five years under the Hatch-Waxman Act, which is designed to
compensate for the patent term lost during the FDA regulatory review process. The length of the patent term extension involves a complex calculation
based on the length of time it takes for regulatory review. A patent term extension under the Hatch-Waxman Act cannot extend the remaining term of a
patent beyond a total of 14 years from the date of product approval and only one patent applicable to an approved drug may be extended. Moreover, a
patent can only be extended once, and thus, if a single patent is applicable to multiple products, it can only be extended based on one product. Similar
provisions are available in Europe and certain other foreign jurisdictions to extend the term of a patent that covers an approved drug.

Competition

If successfully developed, our products will compete with novel therapies developed by biopharmaceutical companies, academic research

institutions, governmental agencies and public and private research institutions, in addition to standard of care treatments. Due to the promising therapeutic
effect of T cell therapies in clinical trials, we anticipate increasing competition from existing and new T cell products, including products that are both
autologous and allogeneic in nature. We also anticipate competition from other cell-based and immune-based therapies in development.

Autologous T cell therapies directed at CD19 have been successfully developed by Novartis, Kite and Bristol-Myers Squibb Company (BMS).

In August 2017, Novartis obtained FDA approval to commercialize Kymriah for the treatment of children and young adults with B-cell ALL that is
refractory or has relapsed at least twice. In May 2018, Kymriah received FDA approval for adults with R/R large B-cell lymphoma. In October 2017, Kite
obtained FDA approval to commercialize Yescarta, for the treatment of adult patients with R/R large B-cell lymphoma. A supplemental BLA for Yescarta
for R/R FL and R/R marginal zone lymphoma was submitted in September 2020. Kite has also received FDA approval for a second autologous CD19-
directed T cell therapy, Tecartus, for use in R/R mantle cell lymphoma. In February 2021, BMS obtained FDA approval for its anti-CD19 autologous T cell
therapy, Breyanzi (lisocabtagene maraleucel), for the treatment of adults with certain types of large B-cell lymphoma who have not responded to, or who
have relapsed after, at least two other types of systemic treatment.

BMS and bluebird bio, Inc. have submitted a BLA to the FDA for approval of an anti-BCMA autologous T cell therapy, idecabtagene vicleucel,

for the treatment of adult patients with multiple myeloma who have received at least three prior therapies. In addition, Johnson & Johnson and partner
Legend Bio have initiated a rolling BLA submission for an anti-BCMA autologous T cell therapy, ciltacabtagene autoleucel, for the same indication.

Autologous T cell therapies are being developed by a number of additional companies, including but not limited to Adaptimmune Therapeutics

PLC, ArsenalBio, Autolus Therapeutics plc, Gilead Sciences, Inc., Gracell Biotechnologies Inc., Iovance Biotherapeutics, Inc., Mustang Bio, Inc., Novartis
International AG, Pact Pharma, Inc., TCR² Therapeutics Inc., Tmunity Therapeutics, Inc., and Unum Therapeutics Inc.

Allogeneic T cell therapies have yet to receive FDA approval though the number of companies developing allogeneic product candidates has
expanded greatly in recent years. This includes Atara Biotherapeutics, Inc., Caribou Biosciences, Inc., Celyad S.A., CRISPR Therapeutics AG, Editas
Medicine, Inc., Gilead Sciences, Inc., Intellia Therapeutics, Inc., Poseida Therapeutics, Inc., Precision Biosciences, Inc., Sana Biotechnology, Inc., and
Tessa Therapeutics Ltd. Additionally, Cellectis has several fully-owned allogeneic CAR programs that could compete with programs that fall outside our
agreement with Cellectis.

There are also cell therapies under development that are based upon cell types other than the common type of T cells used by us and known as

alpha/beta T cells. These include product candidates derived from natural killer cells, natural killer T cells, and gamma/delta T cells. Companies developing
such therapies include Fortress Biotech, Inc., Gamida Cell Ltd., GammaDelta Therapeutics Limited, Fate Therapeutics, Inc., In8bio, Inc., Kuur
Therapeutics Inc., Lyell Immunopharma, Inc., Nkarta, Inc., Artiva Biotherapeutics, Inc. and Takeda Pharmaceutical Company Limited.

Competition may also arise from non-cell based immune oncology platforms. For instance, we may experience competition from companies, such

as Amgen Inc., BMS, Compass Therapeutics, Inc., F. Hoffmann-La Roche AG, Genmab A/S, GlaxoSmithKline plc, Harpoon Therapeutics, Inc.,
MacroGenics, Inc., Merus N.V., Regeneron Pharmaceuticals, Inc., and Xencor Inc., that are pursuing T cell engagers that target both the cancer antigen and
T cell receptor, thus bringing both cancer cells and T cells in close proximity to maximize the likelihood of an immune response to the cancer cells.
Additionally, companies, such as ADC Therapeutics SA, Amgen Inc., Daiichi Sankyo Company, Limited, Gilead Sciences, Inc., GlaxoSmithKline plc,
ImmunoGen, Inc., Seattle Genetics, Inc., Silverback Therapeutics, Inc., and Sutro Biopharma, Inc., are pursuing antibody drug conjugates, which utilize the
targeting ability of antibodies to deliver cell-killing agents directly to cancer cells.

Many of our competitors, either alone or with their collaboration partners, have significantly greater financial resources and expertise in research

and development, pre-clinical testing, clinical trials, manufacturing, and marketing than we do. Future collaborations and mergers and acquisitions may
result in further resource concentration among a smaller number of competitors.

Our commercial potential could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective,

have fewer or less severe side effects, are more convenient or are less expensive than products that we may develop. Our competitors also may obtain FDA
or other regulatory approval for their products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a
strong market position before we are able to enter the market or make our development more complicated. The key competitive factors affecting the
success of all of our programs are likely to be efficacy, safety, convenience, and cost of manufacturing.

These competitors may also vie for a similar pool of qualified scientific and management talent, sites and patient populations for clinical trials, and

investor capital, as well as for technologies complementary to, or necessary for, our programs.

Government Regulation and Product Approval

As a biopharmaceutical company that operates in the United States, we are subject to extensive regulation. Our cell products will be regulated as
biologics. With this classification, commercial production of our products will need to occur in registered facilities in compliance with cGMP for biologics.
The FDA categorizes human cell- or tissue-based products as either minimally manipulated or more than minimally manipulated, and has determined that
more than minimally manipulated products require clinical trials to demonstrate product safety and efficacy and the submission of a BLA for marketing
authorization. Our products are considered more than minimally manipulated and will require evaluation in clinical trials and the submission and approval
of a BLA before we can market them.

26

Table of Contents

Government authorities in the United States (at the federal, state and local level) and in other countries extensively regulate, among other things,

the research, development, testing, manufacturing, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising,
distribution, post-approval monitoring and reporting, marketing and export and import of biopharmaceutical products such as those we are developing. Our
product candidates must be approved by the FDA before they may be legally marketed in the United States and by the appropriate foreign regulatory
agency before they may be legally marketed in foreign countries. Generally, our activities in other countries will be subject to regulation that is similar in
nature and scope as that imposed in the United States, although there can be important differences. Additionally, some significant aspects of regulation in
Europe are addressed in a centralized way, but country-specific regulation remains essential in many respects. The process for obtaining regulatory
marketing approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of
substantial time and financial resources.

U.S. Product Development Process

In the United States, the FDA regulates pharmaceutical and biological products under the Federal Food, Drug and Cosmetic Act (FDCA), the

Public Health Service Act (PHSA) and their implementing regulations. 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. 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 to
administrative or judicial sanctions. FDA sanctions could include, among other actions, refusal to approve pending applications, withdrawal of an approval,
a clinical hold, warning letters, product recalls or withdrawals from the market, product seizures, total or partial suspension of production or distribution
injunctions, fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties. Any agency or judicial enforcement action
could have a material adverse effect on us. The process required by the FDA before a biological product may be marketed in the United States generally
involves the following:

•

•
•
•

•

•
•

•
•

completion of nonclinical laboratory tests and animal studies according to good laboratory practices (GLPs) and applicable requirements for the
humane use of laboratory animals or other applicable regulations;
submission to the FDA of an IND, which must become effective before human clinical trials may begin;
approval by an independent Institutional Review Board (IRB) or ethics committee at each clinical site before the trial is commenced;
performance of adequate and well-controlled human clinical trials according to the FDA’s regulations commonly referred to as good clinical
practices (GCPs) and any additional requirements for the protection of human research patients and their health information, to establish the safety
and efficacy of the proposed biological 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 results of
nonclinical testing and clinical trials;
satisfactory completion of an FDA Advisory Committee review, if applicable;
satisfactory completion of an FDA inspection of the manufacturing facility or facilities where the biological product is produced to assess
compliance with cGMP, to assure that the facilities, methods and controls are adequate to preserve the biological product’s identity, strength,
quality and purity and, if applicable, the FDA’s current good tissue practices (GTPs) for the use of human cellular and tissue products;
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, or licensure, of the BLA.

Before testing any biological product candidate, including our 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 GLPs. 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 raises concerns or
questions regarding the proposed clinical trials and places the 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 safety concerns or non-compliance. If the FDA imposes a clinical hold, trials may not recommence
without FDA authorization and then only under terms authorized by the FDA. Accordingly, we cannot be sure that submission of an IND will result in the
FDA allowing clinical trials to begin, or that, once begun, issues will not arise that suspend or terminate such trials.

Clinical trials involve the administration of the biological product candidate to patients under the supervision of qualified investigators,

generally physicians not employed by or under the trial sponsor’s control. Clinical trials are conducted

27

Table of Contents

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 patients provide informed consent.
Further, each clinical trial must be reviewed and approved by an independent IRB at or servicing each institution at which the clinical trial will be
conducted. An IRB is charged with protecting the welfare and rights of trial participants and considers 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 involving human gene transfer research also must be overseen by an Institutional Biosafety Committee (IBC), a standing committee
to provide peer review of the safety of research plans, procedures, personnel training and environmental risks of work involving recombinant DNA
molecules. IBCs are typically assigned certain review responsibilities relating to the use of recombinant DNA molecules, including reviewing potential
environmental risks, assessing containment levels, and evaluating the adequacy of facilities, personnel training, and compliance with the National Institutes
of Health Guidelines. Some studies also include oversight by an independent group of qualified experts organized by the clinical study sponsor, known as a
data safety monitoring board, which provides authorization for whether or not a study may move forward at designated check points based on access to
certain data from the study and may halt the clinical trial if it determines that there is an unacceptable safety risk for subjects or other grounds, such as no
demonstration of efficacy. There are also requirements governing the reporting of ongoing clinical studies and clinical study results to public registries.

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

•

•

•

Phase 1. The biological product 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 2. The biological product 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 3. Clinical trials are undertaken to further evaluate dosage, clinical efficacy, potency, and safety in an expanded patient population at
geographically dispersed clinical trial sites. These clinical trials are intended to establish the overall risk to benefit ratio of the product and provide
an adequate basis for product labeling.

Post-approval clinical trials, sometimes referred to as Phase 4 clinical trials, may be conducted after initial 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. During all phases of clinical development, regulatory agencies require extensive monitoring and auditing of all clinical activities, clinical data, and
clinical trial investigators. Annual progress reports detailing the results of the clinical trials must be submitted to the FDA. Written IND safety reports must
be promptly submitted to the FDA, and the investigators for serious and unexpected adverse events, any findings from other studies, tests in laboratory
animals or in vitro testing that suggest a significant risk for human patients, 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 1, Phase 2 and Phase 3 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 or terminate a clinical trial at
any time on various grounds, including a finding that the research patients are being exposed to an unacceptable health risk, including risks inferred from
other unrelated immunotherapy trials. 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 biological product has been associated with unexpected serious harm to patients.

Concurrently with clinical trials, companies usually complete additional studies and must also develop additional information about the physical

characteristics of the biological product as well as finalize a process for manufacturing the product in commercial quantities in accordance with cGMP
requirements. To help reduce the risk of the introduction of adventitious agents with use of biological products, the PHSA emphasizes the importance of
manufacturing control for products whose attributes cannot be precisely defined. The manufacturing process must be capable of consistently producing
quality batches of the product candidate and, among other things, the sponsor must develop methods for testing the identity, strength, quality, potency and
purity of the final biological product. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to
demonstrate that the biological 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, FDA approval of a BLA must be obtained before commercial marketing of the

biological product. The BLA submission must include results of product development, laboratory and animal studies, human trials, information on the
manufacture and composition of the product, proposed labeling and other relevant information. 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 significant user fee. The FDA adjusts
the PDUFA user fees on an annual basis. PDUFA also imposes an annual program fee for biological products. 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 or 74 days following submission of the application, the FDA reviews a BLA submitted to determine if it is substantially complete

before the agency accepts it for filing. The FDA may refuse to file any BLA that it deems incomplete or not properly reviewable at the time of submission
and may request additional information. In this event, the BLA must be resubmitted with the additional information. The resubmitted application also is
subject to review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an in-depth substantive review of the
BLA. The FDA reviews the BLA to determine, among other things, whether the proposed product is safe, potent, and/or effective for its intended use, and
has an acceptable purity profile, and whether the product is being manufactured in accordance with cGMP to assure and preserve the product’s identity,
safety, strength, quality, potency and purity. The FDA may refer applications for novel biological products or biological 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 biological product approval process, the FDA
also will determine whether a Risk Evaluation and Mitigation Strategy (REMS) is necessary to assure the safe use of the biological product. A REMS is a
safety strategy to manage a known or potential serious risk associated with a medicine and to enable patients to have continued access to such medicines by
managing their safe use, and could include medication guides, physician communication plans, or elements to assure safe use, such as restricted distribution
methods, patient registries and other risk minimization tools. If the FDA concludes a REMS is needed, the sponsor of the BLA must submit a proposed
REMS. The FDA will not approve a BLA without a REMS, if required.

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 requirements and adequate to assure consistent production of the
product within required specifications. For immunotherapy products, the FDA also will not approve the product if the manufacturer is not in compliance
with the GTPs, to the extent applicable. These are FDA regulations and guidance documents that govern the methods used in, and the facilities and controls
used for, the manufacture of human cells, tissue, and cellular and tissue based products (HCT/Ps), which are human cells or tissue intended for
implantation, transplant, infusion, or transfer into a human recipient. The primary intent of the GTP requirements is to ensure that cell and tissue based
products are manufactured in a manner designed to prevent the introduction, transmission and spread of communicable disease. FDA regulations also
require tissue establishments to register and list their HCT/Ps with the FDA and, when applicable, to evaluate donors through screening and testing.
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 trial requirements and GCP requirements. To assure cGMP, GTP 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 describes all of
the specific deficiencies in the BLA identified by the FDA. The deficiencies identified may be minor, for example, requiring labeling changes, or major, for
example, requiring 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 BLA, addressing all of the
deficiencies identified in the letter, or withdraw the application.

If a product receives regulatory approval, the approval may be limited to specific diseases and dosages 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 or precautions
be included in the product labeling. The FDA may impose restrictions and conditions on product distribution, prescribing, or dispensing in the form of a
risk management plan, or

29

Table of Contents

otherwise limit the scope of any approval. In addition, the FDA may require post marketing clinical trials, sometimes referred to as Phase 4 clinical trials,
designed to further assess a biological product’s safety and effectiveness, and testing and surveillance programs to monitor the safety of approved products
that have been commercialized.

In addition, under the Pediatric Research Equity Act (PREA), a BLA or supplement to a BLA must contain data to assess the safety and

effectiveness of the product 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 FDA may grant deferrals for submission of data or full or partial waivers.

Orphan Drug Designation

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic intended to treat a rare disease or condition, which is
generally a disease or condition that affects fewer than 200,000 individuals in the United States, or more than 200,000 individuals in the United States and
for which there is no reasonable expectation that the cost of developing and making available in the United States a drug or biologic for this type of disease
or condition will be recovered from sales in the United States for that drug or biologic. Orphan drug designation must be requested before submitting a
BLA. After the FDA grants orphan drug designation, the generic identity of the therapeutic agent and its potential orphan use are disclosed publicly by the
FDA. The orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review or approval process.

If a product that has orphan drug designation subsequently receives the first FDA approval for the disease for which it has such designation, the

product is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications, including a full BLA, to market the
same biologic for the same indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan
drug exclusivity. Orphan drug exclusivity does not prevent FDA from approving a different drug or biologic for the same disease or condition, or the same
drug or biologic for a different disease or condition. Among the other benefits of orphan drug designation are tax credits for certain research and a waiver
of the BLA application user fee.

A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it

received orphan designation. In addition, exclusive marketing rights in the United States may be lost if the FDA later determines that the request for
designation was materially defective or if the manufacturer is unable to assure sufficient quantities of the product to meet the needs of patients with the rare
disease or condition.

Expedited Development and Review Programs

The FDA has a fast track program that is intended to expedite or facilitate the process for reviewing new products that meet certain criteria.

Specifically, new 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. Unique to a fast track product, the FDA may consider for review sections of the BLA on a rolling basis
before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the BLA, the FDA agrees to accept
sections of the BLA and determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the
BLA.

Any product, submitted to the FDA for approval, including a product with a fast track designation, may also be eligible for other types of FDA
programs intended to expedite development and review, such as priority review and accelerated approval. A product is eligible for priority review if it has
the potential to provide safe and effective therapy where no satisfactory alternative therapy exists or a significant improvement in the treatment, diagnosis
or prevention of a disease compared to marketed products. The FDA will attempt to direct additional resources to the evaluation of an application for a new
product designated for priority review in an effort to facilitate the review. Additionally, a product may be eligible for accelerated approval. Products studied
for their safety and effectiveness in treating serious or life-threatening diseases or conditions may receive accelerated approval upon a determination that
the product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier
than irreversible morbidity or mortality, that is reasonably likely to predict an effect on 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 drug or biological product receiving accelerated approval perform adequate and well-controlled post-marketing clinical
studies. 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.

30

Table of Contents

Regenerative Medicine Advanced Therapy (RMAT) designation was established by FDA in 2017 to facilitate an efficient development program

for, and expedite review of, any drug that meets the following criteria: (1) it qualifies as a RMAT, which is defined as a cell therapy, therapeutic tissue
engineering product, human cell and tissue product, or any combination product using such therapies or products, with limited exceptions; (2) it is intended
to treat, modify, reverse, or cure a serious or life-threatening disease or condition; and (3) preliminary clinical evidence indicates that the drug has the
potential to address unmet medical needs for such a disease or condition. RMAT designation provides potential benefits that include more frequent
meetings with FDA to discuss the development plan for the product candidate and eligibility for rolling review and priority review. Products granted
RMAT designation may also be eligible for accelerated approval on the basis of a surrogate or intermediate endpoint reasonably likely to predict long-term
clinical benefit, or reliance upon data obtained from a meaningful number of sites, including through expansion to additional sites. Once approved, when
appropriate, the FDA can permit fulfillment of post-approval requirements under accelerated approval through the submission of clinical evidence, clinical
studies, patient registries, or other sources of real world evidence such as electronic health records; through the collection of larger confirmatory datasets;
or through post-approval monitoring of all patients treated with the therapy prior to approval.

Breakthrough therapy designation is also intended to expedite the development and review of products that treat serious or life-threatening

conditions. The designation by FDA requires preliminary clinical evidence that a product candidate, alone or in combination with other drugs and
biologics, demonstrates substantial improvement over currently available therapy on one or more clinically significant endpoints, such as substantial
treatment effects observed early in clinical development. Breakthrough therapy designation comes with all of the benefits of fast track designation, which
means that the sponsor may file sections of the BLA for review on a rolling basis if certain conditions are satisfied, including an agreement with FDA on
the proposed schedule for submission of portions of the application and the payment of applicable user fees before the FDA may initiate a review.

Fast Track designation, priority review, RMAT and breakthrough therapy designation do not change the standards for approval but may expedite

the development or approval process.

In February 2021, the FDA granted fast track designation status to ALLO-501A for the treatment of adult patients with R/R DLBCL.

Post-Approval Requirements

Any products for which we receive FDA approvals are subject to continuing regulation by the FDA, including, among other things, record-

keeping requirements, reporting of adverse experiences with the product, providing the FDA with updated safety and efficacy information, product
sampling and distribution requirements, and complying with FDA promotion and advertising requirements, which include, among others, standards for
direct-to-consumer advertising, restrictions on promoting products for uses or in patient populations that are not described in the product’s approved uses
(known as “off-label use”), limitations on industry-sponsored scientific and educational activities, and requirements for promotional activities involving the
internet. Although a physician may prescribe a legally available product for an off-label use, if the physicians deems such product to be appropriate in
his/her professional medical judgment, a manufacturer may not market or promote off-label uses. However, it is permissible to share in certain
circumstances truthful and not misleading information that is consistent with the product’s approved labeling.

In addition, quality control and manufacturing procedures must continue to conform to applicable manufacturing requirements after approval to

ensure the long-term stability of the product. cGMP regulations require among other things, quality control and quality assurance as well as the
corresponding maintenance of records and documentation and the obligation to investigate and correct any deviations from cGMP. Manufacturers and other
entities involved in the manufacture and distribution of approved products are required to register their establishments with the FDA and certain state
agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP 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, among
other things, recall or withdrawal of the product from the market. In addition, changes to the manufacturing process are strictly regulated, and depending on
the significance of the change, may require prior FDA approval before being implemented. Other types of changes to the approved product, such as adding
new indications and claims, are also subject to further FDA review and approval.

The FDA also may require post-marketing testing, known as Phase 4 testing, and surveillance to monitor the effects of an approved product.
Discovery of previously unknown problems with a product or the failure to comply with applicable FDA requirements can have negative consequences,
including adverse publicity, judicial or administrative enforcement,

31

Table of Contents

warning letters from the FDA, mandated corrective advertising or communications with doctors, and civil or criminal penalties, among others. Newly
discovered or developed safety or effectiveness data may require changes to a product’s approved labeling, including the addition of new warnings and
contraindications, and also may require the implementation of other risk management measures. Also, new government requirements, including those
resulting from new legislation, may be established, or the FDA’s policies may change, which could delay or prevent regulatory approval of our products
under development.

U.S. Marketing Exclusivity

The Biologics Price Competition and Innovation Act (BPCIA) amended the PHSA to authorize the FDA to approve similar versions of

innovative biologics, commonly known as biosimilars. A competitor seeking approval of a biosimilar must file an application to establish its molecule as
highly similar to an approved innovator biologic, among other requirements. The BPCIA, however, bars the FDA from approving biosimilar applications
for 12 years after an innovator biological product receives initial marketing approval. This 12-year period of data exclusivity may be extended by six
months, for a total of 12.5 years, if the FDA requests that the innovator company conduct pediatric clinical investigations of the product.

Depending upon the timing, duration and specifics of the FDA approval of the use of our product candidates, some of our U.S. patents, if

granted, may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly referred
to as the Hatch-Waxman Act. The Hatch-Waxman Act permits a patent restoration term of up to five years, as compensation for patent term lost during
product development and the FDA regulatory review process. However, patent term restoration cannot extend the remaining term of a patent beyond a total
of 14 years from the product’s approval date. The patent term restoration period is generally one-half the time between the effective date of an IND and the
submission date of a BLA plus the time between the submission date of a BLA and the approval of that application. Only one patent applicable to an
approved product is eligible for the extension and the application for the extension must be submitted prior to the expiration of the patent. The U.S. Patent
and Trademark Office, in consultation with the FDA, reviews and approves the application for any patent term extension or restoration. In the future, we
may intend to apply for restoration of patent term for one of our currently owned or licensed patents to add patent life beyond its current expiration date,
depending on the expected length of the clinical trials and other factors involved in the filing of the relevant BLA.

Pediatric exclusivity is another type of regulatory market exclusivity in the United States. Pediatric exclusivity, if granted, adds six months to
existing exclusivity periods and patent terms. This six-month exclusivity, which runs from the end of other exclusivity protection or patent term, may be
granted based on the voluntary completion of a pediatric trial in
accordance with an FDA-issued “Written Request” for such a trial.

Other U.S. Healthcare Laws and Compliance Requirements

In the United States, our activities are potentially subject to regulation by various federal, state and local authorities in addition to the FDA,

including but not limited to, the Centers for Medicare & Medicaid Services (CMS), other divisions of the U.S. Department of Health and Human Services
(HHS) (e.g., the Office of Inspector General, the U.S. Department of Justice (DOJ), and individual U.S. Attorney offices within the DOJ, and state and
local governments). For example, our business practices, including any of our research and future sales, marketing and scientific/educational grant
programs may be required to comply with the anti-fraud and abuse provisions of the Social Security Act, the false claims laws, the patient data privacy and
security provisions of the Health Insurance Portability and Accountability Act (HIPAA), transparency requirements, and similar state, local and foreign
laws, each as amended.

The federal Anti-Kickback Statute prohibits, among other things, any person or entity, from knowingly and willfully offering, paying, soliciting

or receiving any remuneration, directly or indirectly, overtly or covertly, in cash or in kind, to induce or in return for purchasing, leasing, ordering or
arranging for the purchase, lease or order of any item, good, facility or service reimbursable under Medicare, Medicaid or other federal healthcare
programs. The term remuneration has been interpreted broadly to include anything of value. The federal Anti-Kickback Statute has been interpreted to
apply to arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers, formulary managers, and other individuals and
entities on the other. There are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution. The
exceptions and safe harbors are drawn narrowly and require strict compliance in order to offer protection. Practices that involve remuneration that may be
alleged to be intended to induce prescribing, purchasing or recommending may be subject to scrutiny if they do not qualify for an exception or safe harbor.
Failure to meet all of the requirements of a particular applicable statutory exception or regulatory safe harbor does not make the conduct per se illegal under
the Anti-Kickback Statute. Instead, the legality of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of all of its facts
and circumstances. Our practices may not in all cases meet all of the criteria for protection under a statutory exception or regulatory safe harbor.

Additionally, the intent standard under the federal Anti-Kickback Statute was amended by the Patient Protection and Affordable Care Act of
2010, as amended by the Health Care and Education Reconciliation Act of 2010, collectively, the Affordable Care Act, to a stricter standard such that a
person or entity no longer needs to have actual knowledge of the federal Anti-Kickback Statute or specific intent to violate it in order to have committed a
violation. Rather, if “one purpose” of the remuneration is to induce referrals, the federal Anti-Kickback Statute is violated. In addition, the Affordable Care
Act codified case law that a claim that includes items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or
fraudulent claim for purposes of the federal civil False Claims Act (discussed below).

The civil monetary penalties statute imposes penalties against any person or entity who, among other things, is determined to have presented or

caused to be presented a claim to, among others, a federal healthcare program that the person knows or should know is for a medical or other item or
service that was not provided as claimed or is false or fraudulent.

The federal civil False Claims Act prohibits, among other things, any person or entity from knowingly presenting, or causing to be presented, a
false claim for payment to, or approval by, the federal government or knowingly making, using, or causing to be made or used a false record or statement
material to a false or fraudulent claim to the federal government. As a result of a modification made by the Fraud Enforcement and Recovery Act of 2009, a
claim includes “any request or demand” for money or property presented to the U.S. government. For example, pharmaceutical and other healthcare
companies have been, and continue to be, investigated or prosecuted under these laws for allegedly providing free product to customers with the
expectation that the customers would bill federal programs for the product and for causing false claims to be submitted because of the companies’
marketing of the product for unapproved, and thus non-reimbursable, uses.

HIPAA created additional federal criminal statutes that prohibit knowingly and willfully executing, or attempting to execute, a scheme to
defraud or to obtain, by means of false or fraudulent pretenses, representations or promises, any money or property owned by, or under the control or
custody of, any healthcare benefit program, including private third-party payors and knowingly and willfully falsifying, concealing or covering up by trick,
scheme or device, a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for
healthcare benefits, items or services.

Also, many states have similar fraud and abuse statutes or regulations that apply to items and services reimbursed under Medicaid and other

state programs, or, in several states, apply regardless of the payor.

We may be subject to data privacy and security regulations by both the federal government and the states in which we conduct our business.

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act (HITECH) and their implementing regulations, imposes
requirements on certain types of individuals and entities relating to the privacy, security and transmission of individually identifiable health information.
Among other things, HITECH makes HIPAA’s privacy and security standards directly applicable to business associates that are independent contractors or
agents of covered entities that receive or obtain protected health information in connection with providing a service on behalf of a covered entity. HITECH
also created four 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 laws govern the privacy and security of health information in
specified circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts.

Additionally, the federal Physician Payments Sunshine Act within the Affordable Care Act, and its implementing regulations, require that

certain manufacturers of drugs, devices, biological and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health
Insurance Program (with certain exceptions) annually report information to CMS related to certain payments or other transfers of value made or distributed
to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals, or to entities or individuals at the
request of, or designated on behalf of, physicians and teaching hospitals and certain ownership and investment interests held by physicians and their
immediate family members. Beginning in 2022, applicable manufacturers also will be required to report such information regarding its payments and other
transfers of value to physician assistants, nurse practitioners, clinical nurse specialists, anesthesiologist assistants, certified registered nurse anesthetists and
certified nurse midwives during the previous year.

In order to distribute products commercially, we must comply with state laws that require the registration of manufacturers and wholesale

distributors of drug and biological products in a state, including, in certain states, manufacturers and distributors who ship products into the state even if
such manufacturers or distributors have no place of business within the state. Some states also impose requirements on manufacturers and distributors to
establish the pedigree of product in the chain of distribution, including some states that require manufacturers and others to adopt new technology capable
of tracking and

33

Table of Contents

tracing product as it moves through the distribution chain. Several states have enacted legislation requiring pharmaceutical and biotechnology companies to
establish marketing compliance programs, file periodic reports with the state, make periodic public disclosures on sales, marketing, pricing, clinical trials
and other activities, and/or register their sales representatives, as well as to prohibit pharmacies and other healthcare entities from providing certain
physician prescribing data to pharmaceutical and biotechnology companies for use in sales and marketing, and to prohibit certain other sales and marketing
practices. All of our activities are potentially subject to federal and state consumer protection and unfair competition laws.

If our operations are found to be in violation of any of the federal and state healthcare laws described above or any other governmental

regulations that apply to us, we may be subject to significant penalties, including without limitation, civil, criminal and administrative penalties, damages,
fines, disgorgement, imprisonment, exclusion from participation in government programs, such as Medicare and Medicaid, refusal to allow us to enter into
government contracts, contractual damages, reputational harm, administrative burdens, diminished profits and future earnings, additional reporting
requirements and/or oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with
these laws, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of
operations.

Coverage, Pricing and Reimbursement

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

the United States and markets in other countries, sales of any products for which we receive regulatory approval for commercial sale will depend, in part,
on the extent to which third-party payors provide coverage, and establish adequate reimbursement levels for such products. In the United States, third-party
payors include federal and state healthcare programs, private managed care providers, health insurers and other organizations. The process for determining
whether a third-party payor will provide coverage for a product may be separate from the process for setting the price of a product or for establishing the
reimbursement rate that such a payor will pay for the product. Third-party payors may limit coverage to specific products on an approved list, or also
known as a formulary, which might not include all of the FDA-approved products for a particular indication. Third-party payors are increasingly
challenging the price, examining the medical necessity and reviewing the cost-effectiveness of medical products, therapies and services, in addition to
questioning their safety and efficacy. We may need to conduct expensive pharmaco-economic studies in order to demonstrate the medical necessity and
cost-effectiveness of our products, in addition to the costs required to obtain the FDA approvals. Our product candidates may not be considered medically
necessary or cost-effective. A payor’s decision to provide coverage for a product does not imply that an adequate reimbursement rate will be approved.
Further, one payor’s determination to provide coverage for a product does not assure that other payors will also provide coverage for the product. Adequate
third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate return on our investment in product
development.

Different pricing and reimbursement schemes exist in other countries. In the EU, governments influence the price of pharmaceutical products

through their pricing and reimbursement rules and control of national health care systems that fund a large part of the cost of those products to consumers.
Some jurisdictions operate positive and negative list systems under which products may only be marketed once a reimbursement price has been agreed. To
obtain reimbursement or pricing approval, some of these countries may require the completion of clinical trials that compare the cost-effectiveness of a
particular product candidate to currently available therapies. Other member states allow companies to fix their own prices for medicines, but monitor and
control company profits. The downward pressure on health care costs has become very intense. As a result, increasingly high barriers are being erected to
the entry of new products. In addition, in some countries, cross-border imports from low-priced markets exert a commercial pressure on pricing within a
country.

The marketability of any product candidates for which we receive regulatory approval for commercial sale may suffer if the government and

third-party payors fail to provide adequate coverage and reimbursement. In addition, emphasis on managed care in the United States has increased and we
expect will continue to increase the pressure on healthcare pricing. Coverage policies and third-party reimbursement rates may change at any time. Even if
favorable coverage and reimbursement status is attained for one or more products for which we receive regulatory approval, less favorable coverage
policies and reimbursement rates may be implemented in the future.

Healthcare Reform

In the United States and some foreign jurisdictions, there have been, and continue to be, several legislative and regulatory changes and proposed

changes regarding the healthcare system that could prevent or delay marketing approval of product candidates, restrict or regulate post-approval activities,
and affect the ability to profitably sell product candidates for which marketing approval is obtained. Among policy makers and payors in the United States
and elsewhere, there is significant

34

Table of Contents

interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access. In the
United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives.

For example, the Affordable Care Act has substantially changed healthcare financing and delivery by both governmental and private insurers.

Among the Affordable Care Act provisions of importance to the pharmaceutical and biotechnology industries, in addition to those otherwise described
above, are the following:

•

•

•

•

•

•
•

•

•

•
•
•

created an annual, nondeductible fee on any entity that manufactures or imports certain specified branded prescription drugs and biologic agents
apportioned among these entities according to their market share in some government healthcare programs;
increased the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23.1% and 13% of the average
manufacturer price for most branded and generic drugs, respectively, and capped the total rebate amount for innovator drugs at 100% of the
Average Manufacturer Price (AMP);
created a new Medicare Part D coverage gap discount program, in which manufacturers must now agree to offer 70% point-of-sale discounts, off
negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturers’
outpatient drugs to be covered under Medicare Part D;
extended manufacturers’ Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed care
organizations;
expanded eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to additional individuals
and added new mandatory eligibility categories for individuals with income at or below 133% of the federal poverty level, thereby potentially
increasing manufacturers’ Medicaid rebate liability;
expanded of the entities eligible for discounts under the 340B Drug Discount Program;
created a Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research,
along with funding for such research;
expanded healthcare fraud and abuse laws, including the Anti-Kickback Statute and the Foreign Corrupt Practices Act (FCPA), created new
government investigative powers, and enhanced penalties for noncompliance;
created 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;
required reporting of certain financial arrangements with physicians and teaching hospitals;
required annual reporting of certain information regarding drug samples that manufacturers and distributors provide to physicians; and
established a Center for Medicare and Medicaid Innovation at CMS to test innovative payment and service delivery models to lower Medicare and
Medicaid spending.

There have been legal and political challenges to certain aspects of the Affordable Care Act. For example, President Trump signed several

executive orders and other directives designed to delay, circumvent, or loosen certain requirements mandated by the Affordable Care Act. In December
2017, Congress repealed the tax penalty for an individual’s failure to maintain Affordable Care Act-mandated health insurance, commonly known as the
“individual mandate”, as part of the Tax Cuts and Jobs Act of 2017 (Tax Act). In addition, the 2020 federal spending package permanently eliminated,
effective January 1, 2020, the Affordable Care Act’s mandated “Cadillac” tax on high-cost employer-sponsored health coverage and medical device tax
and, effective January 1, 2021, also eliminated the health insurer tax.

Further, the Bipartisan Budget Act of 2018 (BBA), among other things, amended the Affordable Care Act, effective January 1, 2019, to close

the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole”. In December 2018, CMS published a final rule permitting further
collections and payments to and from certain Affordable Care Act qualified health plans and health insurance issuers under the Affordable Care Act risk
adjustment program in response to the outcome of federal district court litigation regarding the method CMS uses to determine this risk adjustment. On
December 14, 2018, a Texas U.S. District Court Judge ruled that the Affordable Care Act is unconstitutional in its entirety because the “individual
mandate” was repealed by Congress as part of the Tax Act. Additionally, on December 18, 2019, the U.S. Court of Appeals for the 5th Circuit upheld the
District Court ruling that the individual mandate was unconstitutional and remanded the case back to the District Court to determine whether the remaining
provisions of the Affordable Care Act are invalid as well. The U.S. Supreme Court is currently reviewing this case, but it is unknown when a decision will
be reached. Although the U.S. Supreme Court has yet to rule on the constitutionality of the Affordable Care Act, on January 28, 2021, President Biden
issued an executive order to initiate a special enrollment period from February 15, 2021 through May 15, 2021 for purposes of obtaining health insurance
coverage through the Affordable Care Act marketplace. The executive order also instructs certain

35

Table of Contents

governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining
Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to
health insurance coverage through Medicaid or the Affordable Care Act. It is unclear how the Supreme Court ruling, other such litigation, and the
healthcare reform measures of the Biden administration will impact the Affordable Care Act.

Further legislation or regulation could be passed that could harm our business, financial condition and results of operations. Other legislative
changes have been proposed and adopted since the Affordable Care Act was enacted. For example, in August 2011, President Obama signed into law the
Budget Control Act of 2011, which, among other things, created the Joint Select Committee on Deficit Reduction to recommend to Congress proposals in
spending reductions. The Joint Select Committee on Deficit Reduction did not achieve a targeted deficit reduction of at least $1.2 trillion for fiscal years
2012 through 2021, triggering the legislation’s automatic reduction to several government programs. This includes aggregate reductions to Medicare
payments to providers of up to 2% per fiscal year, which went into effect beginning on April 1, 2013 and will stay in effect through 2030 unless additional
Congressional action is taken. However, COVID-19 relief support legislation suspended the 2% Medicare sequester from May 1, 2020 through March 31,
2021. In January 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to
several types of providers, including hospitals, imaging centers and cancer treatment centers, and increased the statute of limitations period for the
government to recover overpayments to providers from three to five years.

Additionally, there has been increasing legislative and enforcement interest in the United States with respect to specialty drug pricing practices.

Specifically, there have been several recent U.S. Congressional inquiries and federal and state legislative activity designed to, among other things, bring
more transparency to drug pricing, reduce the cost of prescription drugs under Medicare, review the relationship between pricing and manufacturer patient
programs, and reform government program reimbursement methodologies for drugs. At the federal level, the Trump administration used several means to
propose or implement drug pricing reform, including through federal budget proposals, executive orders and policy initiatives. For example, on July 24,
2020 and September 13, 2020, the Trump administration announced several executive orders related to prescription drug pricing that attempt to implement
several of the administration’s proposals. The FDA also released a final rule, effective November 30, 2020, implementing a portion of the importation
executive order providing guidance for states to build and submit importation plans for drugs from Canada. Further, on November 20, 2020, HHS finalized
a regulation removing safe harbor protection for price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or
through pharmacy benefit managers, unless the price reduction is required by law. The implementation of the rule has been delayed by the Biden
administration from January 1, 2022 to January 1, 2023 in response to ongoing litigation. The rule also creates a new safe harbor for price reductions
reflected at the point-of-sale, as well as a new safe harbor for certain fixed fee arrangements between pharmacy benefit managers and manufacturers, the
implementation of which have also been delayed pending review by the Biden administration until March 22, 2021. On November 20, 2020, CMS issued
an interim final rule implementing President Trump’s Most Favored Nation executive order, which would tie Medicare Part B payments for certain
physician-administered drugs to the lowest price paid in other economically advanced countries, effective January 1, 2021. On December 28, 2020, the
United States District Court in Northern California issued a nationwide preliminary injunction against implementation of the interim final rule. However, it
is unclear whether the Biden administration will work to reverse these measures or pursue similar policy initiatives. Individual states in the United States
have also become increasingly active in passing legislation and implementing regulations designed to control pharmaceutical product pricing, including
price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and,
in some cases, designed to encourage importation from other countries and bulk purchasing.

We anticipate that these and other healthcare reform efforts will continue to result in additional downward pressure on coverage and the price
that we receive for any approved product, and could seriously harm our business. Any reduction in reimbursement from Medicare and other government
programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms
may prevent us from being able to generate revenue, attain profitability, or commercialize our products. Such reforms could have an adverse effect on
anticipated revenue from product candidates that we may successfully develop and for which we may obtain regulatory approval and may affect our overall
financial condition and ability to develop product candidates. Further, it is possible that additional governmental action will be taken in response to the
COVID-19 pandemic.

The Foreign Corrupt Practices Act

The FCPA prohibits any U.S. individual or business from paying, offering, or authorizing payment or offering of anything of value, directly or

indirectly, to any foreign official, political party or candidate for the purpose of influencing any act or decision of the foreign entity in order to assist the
individual or business in obtaining or retaining business. The FCPA also obligates companies whose securities are listed in the United States to comply
with accounting provisions requiring the company to maintain books and records that accurately and fairly reflect all transactions of the corporation,
including

36

Table of Contents

international subsidiaries, and to devise and maintain an adequate system of internal accounting controls for international operations.

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, 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.

Europe / Rest of World Government Regulation

In addition to regulations in the United States, we will be subject to a variety of regulations in other jurisdictions governing, among other things,
clinical trials and any commercial sales and distribution of our products. Whether or not we obtain FDA approval of a product, we must obtain the requisite
approvals from regulatory authorities in foreign countries prior to the commencement of clinical trials or marketing of the product in those countries.
Certain countries outside of the United States have a similar process that requires the submission of a clinical trial application much like the IND prior to
the commencement of human clinical trials. In the EU, for example, a clinical trial application must be submitted to each country’s national health authority
and an independent ethics committee, much like the FDA and IRB, respectively. Once the clinical trial application is approved in accordance with a
country’s requirements, clinical trial development may proceed. Because biologically sourced raw materials are subject to unique contamination risks, their
use may be restricted in some countries.

The requirements and process governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to

country. In all cases, 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.

To obtain regulatory approval of an investigational drug or biological product under EU regulatory systems, we must submit an MAA. The

application used to file the BLA in the United States is similar to that required in the EU, with the exception of, among other things, country-specific
document requirements.

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 or our potential collaborators fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things,

fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

European Union General Data Protection Regulation

In addition to EU regulations related to the approval and commercialization of our products, we may be subject to the EU’s General Data

Protection Regulation (GDPR). The GDPR imposes stringent requirements for controllers and processors of personal data of persons in the EU, including,
for example, more robust disclosures to individuals and a strengthened individual data rights regime, shortened timelines for data breach notifications,
limitations on retention of information, increased requirements pertaining to special categories of data, such as health data, and additional obligations when
we contract with third-party processors in connection with the processing of the personal data. The GDPR also imposes strict rules on the transfer of
personal data out of the European Union to the United States and other third countries. In addition, the GDPR provides that EU member states may make
their own further laws and regulations limiting the processing of personal data, including genetic, biometric or health data.

The GDPR applies extraterritorially, and we may be subject to the GDPR because of our data processing activities that involve the personal data

of individuals located in the European Union, such as in connection with our EU clinical trials. Failure to comply with the requirements of the GDPR and
the applicable national data protection laws of the EU member states may result in fines of up to €20,000,000 or up to 4% of the total worldwide annual
turnover of the preceding financial year,

37

Table of Contents

whichever is higher, and other administrative penalties. GDPR regulations may impose additional responsibility and liability in relation to the personal data
that we process and we may be required to put in place additional mechanisms to ensure compliance with the new data protection rules.

California Consumer Privacy Act

California recently enacted legislation, effective January 1, 2020, that has been dubbed the first “GDPR-like” law in the United States. Known

as the California Consumer Privacy Act (CCPA), it creates new individual privacy rights for consumers (as that word is broadly defined in the law) and
places increased privacy and security obligations on entities handling personal data of consumers or households. The CCPA requires covered companies to
provide new disclosures to California consumers, provides such consumers new ways to opt-out of certain sales of personal information, and allows for a
new cause of action for data breaches. As our business progresses, the CCPA may become applicable and impact (possibly significantly) our business
activities and exemplifies the vulnerability of our business to the evolving regulatory environment related to personal data and protected health information.

Human Capital

As of February 1, 2021, we had 265 total employees, of which 264 are full-time. Of our full-time employees, 69 hold Ph.D. and/or M.D.

degrees, and 195 are engaged in research, development and technical operations. Substantially all of our employees are located in South San Francisco and
Newark, California. Our employees are not represented by labor unions or covered by collective bargaining agreements. We believe that our employee
morale is healthy and consider our relationship with our employees to be good.

We believe our workforce is key to Allogene’s success and we actively focus on the following core elements of human capital: (1) our “One
Allogene” culture, (2) diversity, equity and inclusion, and (3) recruitment, development and retention. Given the COVID-19 pandemic, we have also
focused on COVID-19 safety measures and new ways of generating employee engagement.

One Allogene Culture

We have recently advanced an expression of our culture under the framework of “One Allogene”:

One Allogene

We only succeed as a team.
We accomplish more together than as individuals when we unite as one Allogene community.

We are resilient, because we strive to save the lives of people with cancer.
We come together with purpose, courage and flexibility despite challenges or uncertainty because every potential patient is someone’s partner, parent, child,
sibling or friend.

We aim for excellence and give it our all.
We pursue scientific innovation with a focus on quality and integrity in everything we do to forever change how cancer is treated.

We take ownership and get things done.
We are leaders who embrace urgency, initiative and follow through, with the humility to know each one of us is vital to making AlloCAR T therapy a
reality.

We are good to one another.
We value diversity of thought, background and expertise, we earn each other’s trust, and assume good intention as we collaborate to help patients.

We are creating a scientific revolution.

We are One Allogene

These core elements of our culture are meant to define how and why we do business. In addition, our core values of collaboration, leadership,

innovation and focus help drive our culture and behaviors and are layered into our performance reviews so that we can keep ourselves and our employees
accountable.

38

Diversity, Equity and Inclusion

We are committed to cultivating, fostering, and preserving a culture of diversity, equity and inclusion (DEI). We foster an inclusive environment

through respect, collaboration, and open communication. We embrace and encourage differences in age, color, disability, ethnicity, family or marital status,
gender identity or expression, language, national origin, culture or customs, physical and mental ability, political affiliation, race, religion, sexual
orientation, socio-economic status, veteran status, and other characteristics that make our employees unique. We also embrace differences in experience and
background, and welcome diversity of opinions and thought when making decisions.

As of February 1, 2021, our employees were self-reportedly 49% women. Of our Director-level and above employees, 42% were self-reportedly

women.

In addition, as of February 1, 2021, 66% of all employees were self-reportedly ethnic or racial minorities in the U.S., with 52% Asian, 3% Black

or African American, 5% Hispanic or Latino and 5% of other minority groups or two or more races. Of our Director-level and above employees, 39% were
self-reportedly ethnic or racial minorities in the U.S., with 30% Asian, 1% Black or African American, 1% Hispanic or Latino and 6% of other minority
groups or two or more races.

Although we are proud of our efforts and metrics to date, we are focused on broadening our outreach and increasing opportunities to

underrepresented minorities, including increased recruitment efforts in minority communities by posting our open positions on top job boards for diversity
hiring, participating in diversity focused career fairs and hosting science, technology, engineering, and mathematics (STEM)-based outreach in underserved
communities at the elementary, junior high and high school level. We have and will continue to conduct unconscious bias training and provide guidance
with respect to best practices with a focus on DEI for interviewers. Our recruiters and hiring managers are also encouraged to consider candidates from
underrepresented groups and to have diverse interview panels. In addition, we have an Employee Referral Bonus Program that rewards employees for
referring candidates from underrepresented groups that are ultimately hired.

Our DEI initiatives are applicable to our practices and policies, such as those on recruitment, compensation and professional development. We are

also progressing the ongoing development of an inclusive work environment that encourages:

•
Respectful communication and cooperation between all employees.
• Valuing and soliciting input, feedback and opinions from relevant staff.
•
•

Teamwork and employee participation, permitting the representation of employee perspectives.
Employer and employee contributions to the communities we serve to promote a greater understanding and respect for the diversity.

To champion our efforts in this area, we established a governance structure and formed a DEI Committee as well as an associated DEI Advisory

Board, each of which is comprised of employees of various levels, departments and backgrounds. The DEI Committee formalized a DEI mission statement
and also advanced a DEI policy that sets forth our commitment to the importance of DEI and the responsibility of our employees to adhere to our policy,
including by treating others with dignity and respect at all times. Pursuant to our DEI policy, all employees are also required to attend and complete annual
diversity awareness training to enhance their knowledge to fulfill this responsibility. The DEI Committee and DEI Advisory Board continually work to
identify gaps, respond to feedback provided by peers, and present suggestions on our practices and policies to encourage and enforce an environment in
which all employees feel included and empowered to achieve their best.

We believe in equal pay for equal work. We establish components and ranges of compensation based on market and benchmark data. Within this
context, we strive to pay all employees equitably within a reasonable range, taking into consideration factors such as role; market data; internal equity; job
location; relevant experience; and individual, department and company performance. We also regularly review our compensation practices and analyze our
compensation decisions for individual employees and our workforce as a whole on at least an annual basis. In 2020, we conducted a pay equity analysis
which we believe demonstrated that our compensation practices and structure are equitable. If we identify employees with unjustified pay gaps, we review
and take appropriate action to ensure fidelity between our stated philosophy and actions.

We plan to continue to seek feedback from the DEI Committee, DEI Advisory Board and all our employees to help us achieve our full potential.

Recruitment, Development and Retention

Successful execution of our strategy is dependent on attracting, developing and retaining our employees. We believe our leadership in the field of

allogeneic cell therapy and our culture have allowed us to recruit a talented workforce. In 2020,

39

Table of Contents

we recruited over 90 new employees. Our average time to hire was less than three months and a significant majority of candidates accepted our offers.

We believe our total compensation package also helps recruit and retain our employees. We strive to provide pay, benefits, and services that are

competitive to market and create incentives to attract and retain employees. Our compensation package includes market-competitive pay, broad-based stock
grants, health care and 401(k) plan benefits, paid time off and family leave, among others. We also provide annual incentive bonus opportunities that are
tied to both company performance as well as individual performance to foster a pay-for-performance culture.

Developing our employees is important, and we focus on providing training opportunities and promotional opportunities. Learning and
development, training and other resources are an integral part of retaining our employees and creating a culture of learning and leadership within Allogene.
For instance, we have an annual required manager training that allows managers to learn and practice fundamental management skills to enable them to be
more effective managers. We also train relevant members of our team on important environmental health and safety topics to help ensure we protect our
people and our environment as we operate our business. We encourage our employees to participate and take advantage of a variety of learning and
development resources, including online business skills courses, professional development events, and external training programs based on individual
needs. We also actively review employee performance and business needs every six months that lead to promotional opportunities for employees across
departments and levels.

We believe Allogene is an attractive workplace and our voluntary attrition rate for 2020 was less than 10%. However, we are in a highly
competitive field and geographic region for life science talent and historically have faced proportionally higher attrition among our research, development
and technical operations teams than our general and administrative teams. We believe we will continue to face significant competition for life science
talent.

COVID-19 Employee Safety and Engagement

In March 2020 and in response to the spread of COVID-19 and state and local orders, we limited the number of staff working at our facilities. We

also established an internal COVID-19 task force to ensure timely communication and decision-making in response to COVID-19. For laboratory,
manufacturing and support staff onsite, we implemented new safety protocols, such as facial covering, social distancing and temperature check
requirements. We continue to provide updates regarding COVID-19 and communicate with our employees on a frequent basis. For employees working
remotely, we have provided collaboration tools and resources, including loaning certain office equipment and providing trainings to help leaders effectively
lead and manage remote teams.

In addition, we enhanced and promoted programs to support our culture initiatives and employees’ wellbeing. For instance, we have implemented
Human Resources-led virtual check-ins with our employees (both new hires and tenured employees), conducted surveys regarding culture and COVID-19
related initiatives, and also encouraged skip-level meetings in addition to emphasizing the importance of managers having regular 1:1 meetings with their
team members. We also instituted biweekly virtual town-halls led by our Chief Executive Officer to provide all employees updates relating to our business
and the opportunity to anonymously ask questions of our leadership team. In addition, we provided emergency pay to any employees unable to work due to
the pandemic impact and implemented virtual fitness and meditation classes. We plan to stay engaged with our employees and work to continuously
improve to strengthen Allogene’s culture and commitment to patients and stockholders.

Item 1A. Risk Factors

RISK FACTORS

An investment in shares of our common stock involves a high degree of risk. We have identified the following material factors that make an
investment in our common stock speculative or risky. You should carefully consider the following risk factors, as well as the other information in this
Annual Report. The occurrence of any of the following risks could harm our business, financial condition, results of operations and growth prospects or
cause our actual results to differ materially from those contained in forward-looking statements we have made in this Annual Report and those we may
make from time to time. The risks described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we
currently deem immaterial also may impair our business operations.

Risks Related to Our Business and Industry

We have incurred net losses in every period since our inception and anticipate that we will incur substantial net losses in the future.

We are a clinical-stage biopharmaceutical company and investment in biopharmaceutical product development is highly speculative because it
entails substantial upfront capital expenditures and significant risk that any potential product candidate will fail to demonstrate adequate efficacy or an
acceptable safety profile, gain regulatory approval and become commercially viable. We are advancing an allogeneic CAR T platform of primarily early-
stage product candidates and have no products approved for commercial sale and have not generated any revenue from product sales to date, and we will
continue to incur significant research and development and other expenses related to our ongoing operations. As a result, we are not profitable and have
incurred net losses in each period since our inception. For the year ended December 31, 2020, we reported a net loss of $250.2 million. As of December 31,
2020, we had an accumulated deficit of $646.3 million.

We expect to incur significant expenditures for the foreseeable future, and we expect these expenditures to increase as we continue our research
and development of, and seek regulatory approvals for, product candidates based on our engineered allogeneic T cell platform. Because our allogeneic T
cell product candidates are based on new technologies and will require the creation of inventory of mass-produced, off-the-shelf product, they will require
extensive research and development and have substantial manufacturing and processing costs. In addition, costs to treat patients with relapsed or refractory
cancer and to treat potential side effects that may result from our product candidates can be significant.

Even if we succeed in commercializing one or more of our product candidates, we will continue to incur substantial research and development and

other expenditures to develop and market additional product candidates. 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.

Our engineered allogeneic T cell product candidates represent a novel approach to cancer treatment that creates significant challenges for us.

We are developing a pipeline of allogeneic T cell product candidates that are engineered from healthy donor T cells to express CARs and are

intended for use in any patient with certain cancers. Advancing these novel product candidates creates significant challenges for us, including:

•

•
•

•

manufacturing our product candidates to our or regulatory specifications and in a timely manner to support our clinical trials, and, if
approved, commercialization;

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

understanding and addressing variability in the quality of a donor’s T cells, which could ultimately affect our ability to produce product in a
reliable and consistent manner and treat certain patients;

educating medical personnel regarding the potential side effect profile of our product candidates, if approved, such as the potential adverse
side effects related to cytokine release syndrome (CRS), neurotoxicity, graft-versus-host disease (GvHD), prolonged cytopenia and
neutropenic sepsis;

41

Table of Contents

•

•

•

•

using medicines to preempt or manage adverse side effects of our product candidates, which may not adequately control the side effects
and/or may have other safety risks or a detrimental impact on the efficacy of the treatment;

conditioning patients with chemotherapy and ALLO-647 or other lymphodepletion agents in advance of administering our product
candidates, which may increase the risk of infections and other adverse side effects;

obtaining regulatory approval, as the U.S. Food and Drug Administration (FDA) and other regulatory authorities have limited experience
with development of allogeneic T cell therapies for cancer; and

establishing sales and marketing capabilities upon obtaining any regulatory approval to gain market acceptance of a novel therapy.

Gene-editing is a relatively new technology, and if we are unable to use this technology in our intended product candidates, our revenue opportunities
will be materially limited.

Cellectis’s TALEN technology involves a relatively new approach to gene editing, using sequence-specific DNA-cutting enzymes, or nucleases, to

perform precise and stable modifications in the DNA of living-cells and organisms. Although Cellectis has generated nucleases for many specific gene
sequences, it has not created nucleases for all gene sequences that we may seek to target, and Cellectis may have difficulty creating nucleases for other gene
sequences that we may seek to target, which could limit the usefulness of this technology. This technology may also not be shown to be effective in clinical
studies that Cellectis, we or other licensees of Cellectis technology may conduct, or may be associated with safety issues that may negatively affect our
development programs. For instance, gene-editing may create unintended changes to the DNA such as a non-target site gene-editing, a large deletion, or a
DNA translocation, any of which could lead to oncogenesis. The gene-editing of our product candidates may also not be successful in limiting the risk of
GvHD or premature rejection by the patient.

In addition, the gene-editing industry is rapidly developing, and our competitors may introduce new technologies that render our technology

obsolete or less attractive. New technology could emerge at any point in the development cycle of our product candidates. As competitors use or develop
new technologies, any failures of such technology could adversely impact our program. We also may be placed at a competitive disadvantage, and
competitive pressures may force us to implement new technologies at a substantial cost. In addition, our competitors may have greater financial, technical
and personnel resources that allow them to enjoy technological advantages and may in the future allow them to implement new technologies before we can.
We cannot be certain that we will be able to implement technologies on a timely basis or at a cost that is acceptable to us. If we are unable to maintain
technological advancements consistent with industry standards, our operations and financial condition may be adversely affected.

The COVID-19 global pandemic is adversely impacting our business, including our preclinical studies and clinical trials.

Public health crises such as pandemics or other outbreaks could adversely impact our business. As a result of the COVID-19 pandemic, or similar

pandemics, and government response to pandemics, we have and may in the future experience disruptions that could severely impact our business,
preclinical studies and clinical trials, including:

•
•

•

•

•

•

•

halting or suspending enrollment in our clinical trials;

delays or difficulties in enrolling and retaining patients in our clinical trials;

interruption of key clinical trial activities, such as obtaining laboratory materials for collecting patient samples, clinical trial site data
monitoring and efficacy, safety and translational data collection, processing and analyses, due to limitations on travel imposed or
recommended by federal, state or local governments, employers and others or interruption of clinical trial subject visits, which may impact
the collection and integrity of subject data and clinical study endpoints;

delays or difficulties in initiating or expanding clinical trials, including delays or difficulties with clinical site initiation and recruiting
clinical site investigators and clinical site staff;

increased adverse events and deaths in our clinical trials due to COVID-19 related infections, which may result in increased complications
due to immune suppression from our lymphodepletion regimen;

increased rates of patients withdrawing from our clinical trials following enrollment as a result of contracting COVID-19 or being forced to
quarantine;

diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial
sites and hospital staff supporting the conduct of our clinical trials;

42

Table of Contents

•

•

•

•

delays or disruptions in preclinical experiments and investigational new drug application-enabling studies due to restrictions of on-site staff
and unforeseen circumstances at contract research organizations and vendors;

interruption or delays in the operations of the FDA and comparable foreign regulatory agencies;

interruption of, or delays in receiving, supplies of our raw materials or product candidates from our suppliers and contract manufacturing
organizations (CMOs) due to staffing shortages, production slowdowns or stoppages and disruptions in delivery systems, or due to
prioritization of production for COVID-19 specific therapies or vaccines; and

limitations on employee resources that would otherwise be focused on advancing our business, including because of sickness of employees
or their families, including executive officers and other key employees, the desire of employees to avoid contact with large groups of
people, an increased reliance on working from home or mass transit disruptions.

State and local government response to the pandemic has included "shelter in place", "stay at home" and similar types of orders, which have

limited travel and business operations in our locations, the location of our clinical trial sites, and the location of key vendors, including our CMOs.
Beginning the week of March 9, 2020, the majority of our workforce began working from home. The effects of the stay-at-home orders and our work-from-
home policies may negatively impact productivity, disrupt our business and delay our development programs, regulatory and commercialization timelines,
the magnitude of which will depend, in part, on the length and severity of the restrictions and other limitations on our ability to conduct our business in the
ordinary course. While we, our clinical trials sites and certain of our vendors, including our CMOs, are currently exempt from the orders for certain
essential operations, any of the applicable exemptions may be curtailed or revoked, which would further adversely impact our business.

In addition, the trading prices for our common stock and other biopharmaceutical companies have been highly volatile as a result of the COVID-

19 pandemic. As a result, we may face difficulties raising capital through sales of our common stock or such sales may be on unfavorable terms. Market
and economic deterioration could also adversely impact our portfolio of corporate and government bonds.

The COVID-19 pandemic continues to rapidly evolve. The extent to which the pandemic may impact our business, preclinical studies and clinical
trials will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the duration of the pandemic, travel
restrictions and actions to contain the pandemic or treat its impact, such as social distancing and quarantines or lock-downs in the United States and other
countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the
disease.

We are heavily reliant on our partners for access to key gene editing technology for the manufacturing and development of our product candidates.

A critical aspect to manufacturing allogeneic T cell product candidates involves gene editing the healthy donor T cells in an effort to avoid GvHD
and to limit the patient’s immune system from attacking the allogeneic T cells. GvHD results when allogeneic T cells start recognizing the patient’s normal
tissue as foreign. We use Cellectis’s TALEN gene-editing technology to inactivate a gene coding for TCRα, a key component of the natural antigen
receptor of T cells, to cause the engineered T cells to be incapable of recognizing foreign antigens. Accordingly, when injected into a patient, the intent is
for the engineered T cell not to recognize the tissue of the patient as foreign and thus avoid attacking the patient’s tissue. In addition, we use TALEN gene
editing to inactivate the CD52 gene in donor T cells, which codes for the target of an anti-CD52 monoclonal antibody. Anti-CD52 monoclonal antibodies
deplete CD52 expressing T cells in patients while sparing therapeutic allogeneic T cells lacking CD52. By administering an anti-CD52 antibody prior to
infusing our product candidates, we believe we have the potential to reduce the likelihood of a patient’s immune system from rejecting the engineered
allogeneic T cells for a sufficient period of time to enable a window of persistence during which the engineered allogeneic T cells can actively target and
destroy the cancer cells. However, the antibody may not have the benefits that we anticipate and could have adverse effects.

We rely on an agreement with Cellectis for rights to use TALEN technology for 15 select cancer targets, including BCMA, FLT3, CD70, DLL3
and other targets included in our pipeline. We also rely on Cellectis, through our agreement with Servier, for rights to UCART19, ALLO-501 and ALLO-
501A. We would need an additional license from Cellectis or access to other gene-editing technology to research and develop product candidates directed at
targets not covered by our existing agreements with Cellectis and Servier. In addition, the Cellectis gene-editing technology may fail to produce viable
product candidates. Moreover, both Servier and Cellectis may terminate our respective agreements in the event of a material breach of the agreements, or
upon certain insolvency events. If our agreements were terminated or we required other gene editing

43

Table of Contents

technology, such a license or technology may not be available to us on reasonable terms, or at all, particularly given the limited number of alternative gene-
editing technologies in the market.

In addition, pursuant to the Servier Agreement, we expect Servier to continue to support our clinical trials of ALLO-501 and ALLO-501A for the

treatment of patients with R/R NHL. Should Servier become unable to continue providing its share of financial support for the ALLO-501 and ALLO-
501A clinical trials, our expenses may be greater than we currently expect and we may have difficulty progressing our ongoing and planned clinical trials
in a timely manner. Moreover, as the CALM and PALL clinical trials of UCART19 have completed, we are reliant on Servier for progressing a
development strategy for ALL and any development strategy may face challenges, such as regulatory delays and unforeseen expenses if we consolidate
programs.

Our product candidates are based on novel technologies, which makes it difficult to predict the time and cost of product candidate development and
obtaining regulatory approval.

We have concentrated our research, development and manufacturing efforts on our engineered allogeneic T cell therapy and our future success
depends on the successful development of this therapeutic approach. We are in the early stages of developing our platform and there can be no assurance
that any development problems we experience in the future will not cause significant delays or unanticipated costs, or that such development problems can
be overcome. We may also experience delays in developing a sustainable, reproducible and scalable manufacturing process or transferring that process to
commercial partners, which may prevent us from completing our clinical studies or commercializing our products on a timely or profitable basis, if at all.
In addition, since we are in the early stages of clinical development, we do not know the doses to be evaluated in pivotal trials or, if approved,
commercially. Finding a suitable dose for our cell therapy product candidates as well as ALLO-647 may delay our anticipated clinical development
timelines. In addition, our expectations with regard to our scalability and costs of manufacturing may vary significantly as we develop our product
candidates and understand these critical factors.

We are also advancing product candidates against unexplored targets and with new technology. For example, we are advancing ALLO-316 against

a target, CD70, that has not been validated by any autologous CAR T therapies. ALLO-316 may have limited efficacy or have off-target toxicities. Since
CD70 is found on activated T cells, ALLO-316 may also cause fratricide resulting in the loss of ALLO-316 cells or increase the risk of infections. In
addition, our ALLO-605 product candidate is our first TurboCAR candidate that is designed to mimic cytokine signaling selectively within CAR T cells.
Our TurboCAR product candidates may not demonstrate any of the benefits that we expect. As potentially more potent, our TurboCAR product candidates
may also increase the risk of adverse events, such as CRS and neurotoxicity.

The clinical study requirements of the FDA, European Medicines Agency (EMA) and other regulatory agencies and the criteria these regulators
use to determine the safety and efficacy of a product candidate are determined according to the type, complexity, novelty and intended use and market of
the potential products. The regulatory approval process for novel product candidates such as ours can be more complex and consequently more expensive
and take longer than for other, better known or extensively studied pharmaceutical or other product candidates. We face additional challenges in obtaining
regulatory approval for ALLO-647, which we use as part of our lymphodepletion regimen, and for which we would seek to obtain approval concurrently
with approval of a CAR T cell product candidate. Approvals by the EMA and FDA for existing autologous CAR T therapies, such as Kymriah and
Yescarta, may not be indicative of what these regulators may require for approval of our therapies. Also, while we expect reduced variability in our
products candidates compared to autologous products, we do not have significant clinical data supporting any benefit of lower variability and the use of
healthy donor material may create separate variability challenges for us. More generally, approvals by any regulatory agency may not be indicative of what
any other regulatory agency may require for approval or what such regulatory agencies may require for approval in connection with new product
candidates. Moreover, our product candidates may not perform successfully in clinical trials or may be associated with adverse events that distinguish them
from the autologous CAR T therapies that have previously been approved. For instance, allogeneic product candidates may result in GvHD not experienced
with autologous products. Even if we collect promising initial clinical data of our product candidates, longer-term data may reveal new adverse events or
responses that are not durable. Unexpected clinical outcomes would significantly impact our business.

Our business is highly dependent on the success of our lead product candidates. If we are unable to advance clinical development, obtain approval of
and successfully commercialize our lead product candidates for the treatment of patients in approved indications, our business would be significantly
harmed.

Our business and future success depends on our ability to advance clinical development, obtain regulatory approval of, and then successfully

commercialize, our lead product candidates, including ALLO-501A and ALLO-715. Because ALLO-501, ALLO-501A and ALLO-715 are among the first
allogeneic products to be evaluated in the clinic, the failure of any such product candidate, or the failure of other allogeneic T cell therapies, including for
reasons due to safety, efficacy or durability, may impede our ability to develop our product candidates, and significantly influence physicians’ and
regulators’ opinions in

44

Table of Contents

regards to the viability of our entire pipeline of allogeneic T cell therapies. For instance, we are planning to progress to the Phase 2 portion of the ALPHA2
trial of ALLO-501A by the end of 2021. In order to do so, we will need to complete many objectives, such as continued enrollment in the ALPHA trial and
ALPHA2 Phase 1 portion of the trial, timely patient follow-up, generation of positive Phase 1 data, advancement of cGMP manufacturing of ALLO-501A
and approval from the FDA on any Phase 2 plan. If we are unable to achieve any of these objectives, we may not be able to advance to Phase 2 in a timely
manner or at all, which would significantly harm our business.

All of our product candidates, including our lead product candidates, will require additional clinical and non-clinical development, regulatory
review and approval in multiple jurisdictions, substantial investment, access to sufficient commercial manufacturing capacity and significant marketing
efforts before we can generate any revenue from product sales. In addition, because our other product candidates are based on similar technology as our
lead product candidates, if any of the lead product candidates encounters safety or efficacy problems, manufacturing problems, developmental delays,
regulatory issues or other problems, our development plans and business would be significantly harmed.

Our product candidates may cause undesirable side effects or have other properties that could halt their clinical development, prevent their regulatory
approval, limit their commercial potential or result in significant negative consequences.

Undesirable or unacceptable side effects caused by our product candidates could cause us or regulatory authorities to interrupt, delay or halt

clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other comparable foreign regulatory
authorities. Results of our clinical trials could reveal a high and unacceptable severity and prevalence of side effects or unexpected characteristics.
Approved autologous CAR T therapies and those under development have shown frequent rates of CRS, neurotoxicity, serious infections, prolonged
cytopenia and hypogammaglobulinemia, and adverse events have resulted in the death of patients. We expect similar adverse events for allogeneic CAR T
product candidates.

Our allogeneic CAR T cell product candidates may also cause unique adverse events related to the differences between the donor and patients,

such as GvHD or infusion reactions. In addition, we utilize a lymphodepletion regimen, which generally includes fludarabine, cyclophosphamide and
ALLO-647, that may cause serious adverse events. For instance, because the regimen will cause a transient and sometimes prolonged immune suppression,
patients will have an increased risk of infection, such as to COVID-19, that may be unable to be cleared by the patient and ultimately lead to death. Our
lymphodepletion regimen has caused and may also cause prolonged cytopenia. We are also exploring various dosing strategies for lymphodepletion in our
clinical trials, such as higher and lower dosing of ALLO-647 in combination with fludarabine and cyclophosphamide, which may increase the risk of
serious adverse events.

In our and Servier's clinical trials of allogeneic CAR T product candidates, the most common severe or life threatening adverse events resulted

from serious infections, prolonged cytopenia, prolonged pancytopenia, hypokalemia, multiple organ dysfunction syndrome and neutropenic sepsis. As
reported, patients have died from adverse events and future patients may also experience toxicity resulting in death. For additional safety data, please see
"Business--Product Pipeline and Development Strategy".

As we treat and re-treat more patients with our product candidates in our clinical trials, new less common side effects may also emerge. For
instance, our allogeneic CAR T cell product candidates undergo gene engineering by using lentivirus and TALEN nucleases that can cause insertion,
deletion, or chromosomal translocation. These changes can cause allogeneic CAR T cells to proliferate uncontrollably and may cause adverse events. In
addition, we may combine the use of our product candidates with other investigational therapies that may cause separate adverse events or events related to
the combination. For instance, we are advancing a combination of ALLO-715 and nirogacestat, a gamma secretase inhibitor, in a cohort in the
UNIVERSAL trial. The most common adverse events relating to nirogacestat in prior trials have included diarrhea, nausea, fatigue, hypophosphatemia,
vomiting, rash, cough, decreased appetite, pyrexia and hypokalemia. These or other adverse events could result in the suspension of therapy or otherwise
adversely impact the UNIVERSAL trial.

If unacceptable toxicities arise in the development of our product candidates, we could suspend or terminate our trials or the FDA or comparable
foreign regulatory authorities could order us to cease clinical trials or deny approval of our product candidates for any or all targeted indications. The data
safety monitoring board may also suspend or terminate a clinical trial at any time on various grounds, including a finding that the research patients are
being exposed to an unacceptable health risk, including risks inferred from other unrelated immunotherapy trials. Treatment-related side effects could also
affect patient recruitment or the ability of enrolled subjects to complete the trial or result in potential product liability claims. In addition, these side effects
may not be appropriately recognized or managed by the treating medical staff, as toxicities resulting from T cell therapy are not normally encountered in
the general patient population and by medical personnel. We have trained and expect to have to train medical personnel using CAR T cell product
candidates to understand the side effect profile of our

45

Table of Contents

product candidates for both our clinical trials and upon any commercialization of any of our product candidates. Inadequate training in recognizing or
managing the potential side effects of our product candidates could result in patient deaths. Any of these occurrences may harm our business, financial
condition and prospects significantly.

Our clinical trials may fail to demonstrate the safety and efficacy of any of our product candidates, which would prevent or delay regulatory approval
and commercialization.

Before obtaining regulatory approvals for the commercial sale of our product candidates, we must demonstrate through lengthy, complex and

expensive preclinical testing and clinical trials that our product candidates are both safe and effective for use in each target indication. Clinical testing is
expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the clinical trial process. The
results of preclinical studies and early clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials, including in
any post-approval studies.

There is typically an extremely high rate of attrition from the failure of product candidates proceeding through clinical trials. Product candidates in
later stages of clinical trials may fail to show the desired safety and efficacy profile despite having progressed through preclinical studies and initial clinical
trials. A number of companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy,
insufficient durability of efficacy or unacceptable safety issues, notwithstanding promising results in earlier trials. Most product candidates that commence
clinical trials are never approved as products.

In addition, for ongoing and any future trials that may be completed, we cannot guarantee that the FDA or foreign regulatory authorities will

interpret the results as we do, and more trials could be required before we submit our product candidates for approval. To the extent that the results of the
trials are not satisfactory to the FDA or foreign regulatory authorities for support of a marketing application, approval of our product candidates may be
significantly delayed, or we may be required to expend significant additional resources, which may not be available to us, to conduct additional trials in
support of potential approval of our product candidates.

Initial, interim and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data become
available and are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publish initial, interim or preliminary data from our clinical studies. Interim data from clinical trials that we may
complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data
become available. For instance, we have published preliminary data from the ALPHA trial and UNIVERSAL trial, however such results are preliminary in
nature, do not bear statistical significance and should not be viewed as predictive of ultimate success. It is possible that such results will not continue or
may not be repeated in ongoing or future clinical trials of anti-CD19 or anti-BCMA CAR T cell product candidates or our other product candidates.

Preliminary data also remain subject to audit and verification procedures that may result in the final data being materially different from the

preliminary data we previously published. As a result, initial, interim and preliminary data should be viewed with caution until the final data are available.
Adverse differences between preliminary or interim data and final data could significantly harm our business prospects.

We may not be able to file INDs to commence additional clinical trials on the timelines we expect, and even if we are able to, the FDA may not permit
us to proceed.

We plan to submit INDs for additional product candidates in the future, including an IND for ALLO-605 in the first half of 2021. We cannot be
sure that submission of an IND or IND amendment will result in the FDA allowing testing and clinical trials to begin, or that, once begun, issues will not
arise that suspend or terminate such clinical trials. The manufacturing of allogeneic CAR T cell therapy remains an emerging and evolving field.
Accordingly, we expect chemistry, manufacturing and control related topics, including product specification, will be a focus of IND reviews, which may
delay the clearance of INDs or IND amendments. For instance, we intend to optimize the manufacturing of our product candidates, including ALLO-501A,
and regulatory authorities may require additional studies or clinical data to support the changes, which could delay our clinical trial timelines, including the
Phase 2 portion of the ALPHA2 trial. Additionally, even if such regulatory authorities agree with the design and implementation of the clinical trials set
forth in an IND, IND amendment or clinical trial application, we cannot guarantee that such regulatory authorities will not change their requirements in the
future.

In addition, we submitted a standalone cross-reference IND for ALLO-647, which is being used as part of lymphodepletion in all our clinical

trials. While our IND has been accepted, we have to update the IND for any new IND or

46

Table of Contents

IND amendment relating to our allogeneic CAR T cell product candidates and we plan to update the IND as we finalize pivotal manufacturing of ALLO-
647 at one of our CMOs. Any regulatory issues related to the review of our ALLO-647 IND updates or to the development of ALLO-647 could delay
development of our allogeneic CAR T cell product candidates and significantly affect our business.

We may encounter substantial delays in our clinical trials, or may not be able to conduct our trials on the timelines we expect.

Clinical testing is expensive, time consuming and subject to uncertainty. We cannot guarantee that any clinical studies will be conducted as

planned or completed on schedule, if at all. Even if our trials begin as planned, issues may arise that could suspend or terminate such clinical trials. A
failure of one or more clinical study can occur at any stage of testing, and our future clinical studies may not be successful. Events that may prevent
successful or timely completion of clinical development include:

•
•

•
•
•

•

•
•

•
•

•
•

•

delays in developing suitable assays for screening patients for eligibility for trials with respect to certain product candidates;

delays in reaching a consensus with regulatory agencies on study design;

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

delays in obtaining required institutional review board (IRB) approval at each clinical study site;

imposition of a temporary or permanent clinical hold by regulatory agencies for a number of reasons, including after review of an IND
application or amendment, or equivalent application or amendment; as a result of a new safety finding that presents unreasonable risk to
clinical trial participants; a negative finding from an inspection of our clinical study operations or study sites; developments on trials
conducted by competitors for related technology that raises FDA concerns about risk to patients of the technology broadly; or if FDA finds
that the investigational protocol or plan is clearly deficient to meet its stated objectives;

delays in recruiting suitable patients to participate in our clinical studies;

difficulty collaborating with patient groups and investigators;

failure by our CROs, other third parties or us to adhere to clinical study requirements;

failure to perform in accordance with the FDA’s good clinical practice (GCP) requirements or applicable regulatory guidelines in other
countries;

transfer of manufacturing processes to any new CMO or our own manufacturing facilities or any other development or commercialization
partner for the manufacture of product candidates;

delays in having patients complete participation in a study or return for post-treatment follow-up;

patients dropping out of a study;

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

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

changes in the standard of care on which a clinical development plan was based, which may require new or additional trials;

the cost of clinical studies of our product candidates being greater than we anticipate;

clinical studies of our product candidates producing negative or inconclusive results, which may result in our deciding, or regulators
requiring us, to conduct additional clinical studies or abandon product development programs;

delays or failure to secure supply agreements with suitable raw material suppliers, or any failures by suppliers to meet our quantity or
quality requirements for necessary raw materials, including due to suppliers prioritizing COVID-19 specific treatments or vaccines; and

delays in manufacturing, testing, releasing, validating, or importing/exporting sufficient stable quantities of our product candidates for use
in clinical studies or the inability to do any of the foregoing, including due to our CMOs or other vendors prioritizing COVID-19 specific
treatments or vaccines.

The COVID-19 pandemic may also increase the risk of certain of the events described above and delay our development timelines. Any inability
to successfully complete preclinical and clinical development could result in additional costs to us or impair our ability to generate revenue. In addition, if
we make manufacturing or formulation changes to our product candidates, we may be required to or we may elect to conduct additional studies to bridge
our modified product candidates to earlier versions. Clinical study delays could also shorten any periods during which our products have patent protection
and may allow our competitors to bring products to market before we do, which could impair our ability to successfully commercialize our product
candidates and may harm our business and results of operations.

Monitoring and managing toxicities in patients receiving our product candidates is challenging, which could adversely affect our ability to obtain
regulatory approval and commercialize.

For our ongoing and planned clinical trials of our product candidates, we contract or will contract with academic medical centers and hospitals

experienced in the assessment and management of toxicities arising during clinical trials. Nonetheless, these centers and hospitals may have difficulty
observing patients and treating toxicities, which may be more challenging due to personnel changes, inexperience, shift changes, house staff coverage or
related issues. This could lead to more severe or prolonged toxicities or even patient deaths, which could result in us or the FDA delaying, suspending or
terminating one or more of our clinical trials, and which could jeopardize regulatory approval. We also expect the centers using our product candidates, if
approved, on a commercial basis could have similar difficulty in managing adverse events. Medicines used at centers to help manage adverse side effects of
our product candidates may not adequately control the side effects and/or may have a detrimental impact on the efficacy of the treatment. Use of these
medicines may increase with new physicians and centers administering our product candidates.

If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise adversely affected.

We may experience difficulties in patient enrollment in our clinical trials for a variety of reasons. The timely completion of clinical trials in
accordance with their protocols depends, among other things, on our ability to enroll a sufficient number of patients who remain in the study until its
conclusion. The COVID-19 pandemic, including the travel and business restrictions imposed by government authorities in response to the pandemic, have
resulted in, and may continue to cause, reduced enrollment and may also create challenges to related clinical trial activities. In addition, the enrollment of
patients depends on many factors, including:

•
•
•

•
•

•

•
•

the patient eligibility criteria defined in the protocol;

the size of the patient population required for analysis of the trial’s primary endpoints;

the proximity of patients to study sites;

the design of the trial;

our ability to recruit clinical trial investigators with the appropriate competencies and experience;

our ability to obtain and maintain patient consents;

the competition from approved products and from product candidates in other clinical trials; and

the risk that patients enrolled in clinical trials will drop out of the trials before the infusion of our product candidates or trial completion.

Since we only need to conduct a limited number of manufacturing runs to generate clinical supply, the diversity of our supply is limited during

clinical trials. As a result, some patients may have antibodies to certain donor specific antigens that may interact with our product candidates, which would
render the patients ineligible for treatment.

48

Table of Contents

In addition, prior treatment with rituximab may interfere with ALLO-501 as ALLO-501 contains rituximab recognition domains. Since rituximab

is a typical part of a treatment regimen for a patient with NHL, patient eligibility for the ALLO-501 trial may be limited. Patients may also undergo
plasmapheresis to remove rituximab prior to infusion of ALLO-501, which may cause separate adverse effects. We have removed the rituximab recognition
domains in the second generation of ALLO-501, known as ALLO-501A, which we believe will potentially facilitate treatment of patients who were
recently treated with rituximab. However, ALLO-501A may not behave as expected and may be challenging to develop or manufacture.

Our clinical trials will also compete with other clinical trials for product candidates that are in the same therapeutic areas as our product
candidates, and this competition will reduce the number and types of patients available to us because some patients who might have opted to enroll in our
trials may instead opt to enroll in a trial being conducted by one of our competitors. Since the number of qualified clinical investigators is limited, some of
our clinical trial sites are also being used by some of our competitors, which may reduce the number of patients who are available for our clinical trials in
that clinical trial site.

Moreover, because our product candidates represent a departure from more commonly used methods for cancer treatment, potential patients and

their doctors may be inclined to use conventional therapies, such as chemotherapy and hematopoietic cell transplantation or autologous CAR T cell
therapies, rather than enroll patients in our clinical trial, including if our product candidates have or are perceived to have additional safety or efficacy risks
or if using our product candidates may affect insurance coverage of conventional therapies. Patients eligible for allogeneic CAR T cell therapies but
ineligible for autologous CAR T cell therapies due to aggressive cancer and inability to wait for autologous CAR T cell therapies may be at greater risk for
complications and death from therapy.

Delays in patient enrollment may result in increased costs or may affect the timing or outcome of our ongoing clinical trial and planned clinical

trials, which could prevent completion of these trials and adversely affect our ability to advance the development of our product candidates.

The market opportunities for our product candidates may be limited to those patients who are ineligible for or have failed prior treatments and may be
small.

The FDA often approves new therapies initially only for use in patients with R/R metastatic disease. We expect to initially seek approval of our

product candidates in this setting. Subsequently, for those products that prove to be sufficiently beneficial, if any, we would expect to seek approval in
earlier lines of treatment. There is no guarantee that our product candidates, even if approved, would be approved for earlier lines of therapy, and, prior to
any such approvals, we will have to conduct additional clinical trials, including potentially comparative trials against approved therapies. We are also
targeting a similar patient population as autologous CAR T product candidates, including approved autologous CAR T products. Our therapies may not be
as safe and effective as autologous CAR T therapies and may only be approved for patients who are ineligible for autologous CAR T therapy.

Our projections of both the number of patients who have the cancers we are targeting, as well as the subset of patients with these cancers in a
position to receive second or later lines of therapy and who have the potential to benefit from treatment with our product candidates, are based on our
beliefs and estimates. These estimates have been derived from a variety of sources, including scientific literature, surveys of clinics, patient foundations, or
market research and may prove to be incorrect. Further, new studies may change the estimated incidence or prevalence of these cancers. The number of
patients may turn out to be lower than expected. Additionally, the potentially addressable patient population for our product candidates may be limited or
may not be amenable to treatment with our product candidates. For instance, we expect ALLO-501A to initially target a small patient population that
suffers from R/R NHL. Even if we obtain significant market share for our product candidates, because the potential target populations are small, we may
never achieve profitability without obtaining regulatory approval for additional indications.

Our development strategy relies on incorporating an anti-CD52 monoclonal antibody as part of the lymphodepletion preconditioning regimen prior to
infusing allogeneic CAR T cell product candidates.

We utilize an anti-CD52 monoclonal antibody as part of a lymphodepletion regimen to be infused prior to infusing our product candidates. While

we believe an anti-CD52 antibody may be able to reduce the likelihood of a patient’s immune system rejecting the engineered allogeneic T cells for a
sufficient period of time to enable a window of persistence during which such engineered allogeneic T cells can actively target and destroy cancer cells, the
antibody may not have the benefits that we anticipate and could have adverse effects. For instance, our lymphodepletion regimen, including using an anti-
CD52 antibody, will cause a transient and sometimes prolonged immune suppression that is associated with an increased risk of infection, such as to
COVID-19, that may be unable to be cleared by the patient and ultimately lead to death.

49

Table of Contents

In the prior CALM and PALL trials, a commercially available monoclonal antibody, alemtuzumab, that binds CD52 was used. Alemtuzumab is

known to have risk of causing certain adverse events. In 2020, the EMA completed a pharmacovigilance review of alemtuzumab in the context of the
treatment of multiple sclerosis following reports of immune-mediated conditions and problems affecting the heart and blood vessels, including fatal cases.
The EMA recommended that alemtuzumab should not be used in patients with certain heart, circulation or bleeding disorders or in patients who have
autoimmune disorders other than multiple sclerosis. The EMA also recommended that alemtuzumab only be given in a hospital with ready access to
intensive care facilities and specialists who can manage serious adverse reactions. Based on the recommendations, we have added relevant new safety
information to certain of our clinical trial documentation, including informed consent forms. Our product candidates will also continue to be administered
at specialized centers, which are experienced at managing patients with advanced malignancies as well as toxicities associated with immunomodulatory
therapies. We will continue to monitor any new safety information that will be reported or added to the product labels of alemtuzumab. If the EMA or other
regulatory agencies further limit the use of alemtuzumab or anti-CD52 antibodies, our clinical program would be adversely affected.

To secure our own readily available source of anti-CD52 antibody, we are developing our own monoclonal anti-CD52 antibody, ALLO-647,

which we are using in our clinical trials. ALLO-647 may cause serious adverse events that alemtuzumab may cause, including fatal adverse events,
immune thrombocytopenia, glomerular nephropathies, thyroid disorders, autoimmune cytopenias, autoimmune hepatitis, hemophagocytic
lymphohistiocytosis, acquired hemophilia and infections, stroke, and progressive multifocal leukoencephalopathy. In addition, we are exploring various
dosing strategies for lymphodepletion in our clinical trials, such as higher and lower dosing of ALLO-647 in combination with fludarabine and
cyclophosphamide, which may increase the risk of serious adverse events. See "Business--Product Pipeline and Development Strategy" for information on
safety events.

If we are unable to successfully develop and manufacture ALLO-647 in the timeframe we anticipate, or at all, or if regulatory authorities do not

approve the use of ALLO-647 in combination with our allogeneic T cell product candidates, we may be unable to source alemtuzumab and our engineered
allogeneic T cell product candidates may be less effective, which could result in delays in our product development efforts and/or the commercial potential
of our product candidates.

We intend to operate our own cell therapy manufacturing facility, which will require significant resources and we may fail to successfully operate our
facility, which could adversely affect our clinical trials and the commercial viability of our product candidates.

We may not be able to achieve clinical or commercial manufacturing and cell processing on our own or at our CMO, including mass-producing

off-the-shelf product to satisfy demands for any of our product candidates. While we believe the manufacturing and processing approaches are appropriate
to support our clinical product development, we have limited experience in managing the allogeneic T cell engineering process, and our allogeneic
processes may be more difficult or more expensive than the approaches taken by our competitors. We cannot be sure that the manufacturing processes
employed by us or the technologies that we incorporate for manufacturing will result in T cells that will be safe and effective.

In February 2019, we entered into a lease for approximately 118,000 square feet to develop a state-of-the-art cell therapy manufacturing facility in
Newark, California. While we expect to initiate manufacturing under current good manufacturing practices (cGMP) in 2021, any business interruptions or
delays to our validation or commissioning efforts, securing equipment and raw materials, or obtaining appropriate regulatory or licensing approvals, in each
case which may be more likely as a result of the COVID-19 pandemic, will delay our manufacturing timelines.

Any changes in manufacturing of our product candidates currently in the clinic, including introducing product candidates manufactured at our

facility into any ongoing clinical trials, will require that we meet certain regulatory conditions, such as establishing comparability with the product
candidates manufactured at our CMO, and our inability to meet such conditions may result in a delay in using our manufacturing facility for production or
extend our clinical trial timelines.

We also do not yet have sufficient information to reliably estimate the cost of the clinical and commercial manufacturing and processing of our

product candidates, and the actual cost to manufacture and process our product candidates could materially and adversely affect the commercial viability of
our product candidates. In addition, the ultimate clinical and any commercial dose and treatment regimen will affect our ability to scale and our costs per
dose. For instance, because ALLO-715 may require a higher dose than ALLO-501A, it is possible that it may be more difficult to scale ALLO-715
production to meet any demand. As a result, we may never be able to develop a commercially viable product. The commercial manufacturing facility we
build will also require FDA approval, which we may never obtain. Even if approved, we would be subject to ongoing periodic unannounced inspection by
the FDA, the Drug Enforcement Administration and corresponding state agencies to ensure strict compliance with cGMP, and other government
regulations.

The manufacture of biopharmaceutical products is complex and requires significant expertise, including the development of advanced

manufacturing techniques and process controls. Manufacturers of cell therapy products often encounter difficulties in production, particularly in scaling out
and validating initial production and ensuring the absence of contamination. These problems include difficulties with production costs and yields, quality
control, including stability of the product, quality assurance testing, operator error, shortages of qualified personnel, as well as compliance with strictly
enforced federal, state and foreign regulations. The application of new regulatory guidelines or parameters, such as those related to release testing, may also
adversely affect our ability to manufacture our product candidates. Furthermore, if contaminants are discovered in our supply of product candidates or in
the manufacturing facilities, such supply may have to be discarded and our manufacturing facilities may need to be closed for an extended period of time to
investigate and remedy the contamination. We cannot assure you that any stability or other issues relating to the manufacture of our product candidates will
not occur in the future.

We, our CMOs or any other of our or their vendors may fail to manage the logistics of storing and shipping our raw materials and product
candidates. Storage failures and shipment delays and problems caused by us, our vendors or other factors not in our control, such as weather, could result in
the inability to manufacture product, the loss of usable product or prevent or delay the delivery of product candidates to patients.

We may also experience manufacturing difficulties due to resource constraints or as a result of labor disputes. If we were to encounter any of these

difficulties, our ability to provide our product candidates to patients would be jeopardized.

We currently have no marketing and sales organization and as a company have no experience in marketing products. If we are unable to establish
marketing and sales capabilities or enter into agreements with third parties to market and sell our product candidates, we may not be able to generate
product revenue.

We currently have no sales, marketing or distribution capabilities and as a company have no experience in marketing products. We intend to

develop an in-house marketing organization and sales force, which will require significant capital expenditures, management resources and time. We will
have to compete with other pharmaceutical and biotechnology companies to recruit, hire, train and retain marketing and sales personnel.

If we are unable or decide not to establish internal sales, marketing and distribution capabilities, we will pursue collaborative arrangements

regarding the sales and marketing of our products; however, there can be no assurance that we will be able to establish or maintain such collaborative
arrangements, or if we are able to do so, that they will have effective sales forces. Any revenue we receive will depend upon the efforts of such third
parties, which may not be successful. We may have little or no control over the marketing and sales efforts of such third parties and our revenue from
product sales may be lower than if we had commercialized our product candidates ourselves. We also face competition in our search for third parties to
assist us with the sales and marketing efforts of our product candidates.

There can be no assurance that we will be able to develop in-house sales and distribution capabilities or establish or maintain relationships with

third-party collaborators to commercialize any product that receives regulatory approval in the United States or in other markets.

A variety of risks associated with conducting research and clinical trials abroad and marketing our product candidates internationally could materially
adversely affect our business.

We plan to globally develop our product candidates. Accordingly, we expect that we will be subject to additional risks related to operating in

foreign countries, including:

•

•
•

•

•
•

•
•

differing regulatory requirements in foreign countries;

unexpected changes in tariffs, trade barriers, price and exchange controls and other regulatory requirements;

differing standards for the conduct of clinical trials;

increased difficulties in managing the logistics and transportation of storing and shipping product candidates produced in the United States
and shipping the product candidate to the patient abroad;

import and export requirements and restrictions;

economic weakness, including inflation, or political instability in particular foreign economies and markets;

compliance with tax, employment, immigration and labor laws for employees living or traveling abroad;

foreign taxes, including withholding of payroll taxes;

51

foreign currency fluctuations, which could result in increased operating expenses and reduced revenue, and other obligations incident to
doing business in another country;

difficulties staffing and managing foreign operations;

workforce uncertainty in countries where labor unrest is more common than in the United States;

differing payor reimbursement regimes, governmental payors or patient self-pay systems, and price controls;

potential liability under the Foreign Corrupt Practices Act of 1977 or comparable foreign regulations;

challenges enforcing our contractual and intellectual property rights, especially in those foreign countries that do not respect and protect
intellectual property rights to the same extent as the United States;

production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and

business interruptions resulting from the COVID-19 pandemic or other natural or man-made disasters, including earthquakes, tsunamis,
fires or other medical epidemics, or geo-political actions, including war and terrorism.

These and other risks associated with our collaborations with Servier and Cellectis, each based in France, our collaboration with Notch

Therapeutics Inc. (Notch), based in Canada, and our joint venture for China, Taiwan, South Korea and Singapore with Overland Pharmaceuticals (CY) Inc.,
may materially adversely affect our ability to attain or maintain profitable operations.

We face significant competition from other biotechnology and pharmaceutical companies, and our operating results will suffer if we fail to compete
effectively.

The biopharmaceutical industry, and the immuno-oncology industry specifically, is characterized by intense competition and rapid innovation. Our

competitors may be able to develop other compounds or drugs that are able to achieve similar or better results. Our potential competitors include major
multinational pharmaceutical companies, established biotechnology companies, specialty pharmaceutical companies and universities and other research
institutions. Many of our competitors have substantially greater financial, technical and other resources, such as larger research and development staff and
experienced marketing and manufacturing organizations and well-established sales forces. Smaller or early-stage companies may also prove to be
significant competitors, particularly through collaborative arrangements with large, established companies. Mergers and acquisitions in the biotechnology
and pharmaceutical industries may result in even more resources being concentrated in our competitors. Competition may increase further as a result of
advances in the commercial applicability of technologies and greater availability of capital for investment in these industries. Our competitors, either alone
or with collaborative partners, may succeed in developing, acquiring or licensing on an exclusive basis drug or biologic products that are more effective,
safer, more easily commercialized or less costly than our product candidates or may develop proprietary technologies or secure patent protection that we
may need for the development of our technologies and products.

Specifically, engineered T cells face significant competition from multiple companies. Success of other therapies could impact our regulatory

strategy and delay or prevent regulatory approval of our product candidates. Even if we obtain regulatory approval of our product candidates, the
availability and price of our competitors’ products could limit the demand and the price we are able to charge for our product candidates. We may not be
able to implement our business plan if the acceptance of our product candidates is inhibited by price competition or the reluctance of physicians to switch
from existing methods of treatment to our product candidates, or if physicians switch to other new drug or biologic products or choose to reserve our
product candidates for use in limited circumstances. For additional information regarding our competition, see “Item 1. Business—Competition” in our
Annual Report.

We are highly dependent on our key personnel, and if we are not successful in attracting and retaining highly qualified personnel, we may not be able
to successfully implement our business strategy.

Our ability to compete in the highly competitive biotechnology and pharmaceutical industries depends upon our ability to attract and retain highly

qualified managerial, scientific and medical personnel. We are highly dependent on our management, scientific and medical personnel, including our
Executive Chair, our President and Chief Executive Officer, our Chief Financial Officer, our Executive Vice President of Research & Development and
Chief Medical Officer, our Chief Technical Officer, and our General Counsel. The loss of the services of any of our executive officers, other key
employees, and other scientific and medical advisors, and our inability to find suitable replacements could result in delays in product development and
harm our business.

We conduct substantially all of our operations at our facilities in South San Francisco. This region is headquarters to many other

biopharmaceutical companies and many academic and research institutions. Competition for skilled personnel in our market is intense and may limit our
ability to hire and retain highly qualified personnel on acceptable terms or at all.

To induce valuable employees to remain at our company, in addition to salary and cash incentives, we have provided stock options and restricted
stock unit (RSU) awards that vest over time. The value to employees of stock options and RSU awards that vest over time may be significantly affected by
movements in our stock price that are beyond our control and may at any time be insufficient to counteract more lucrative offers from other companies.
Despite our efforts to retain valuable employees, members of our management, scientific and development teams may terminate their employment with us
on short notice. Although we have employment agreements with our key employees, these employment agreements provide for at-will employment, which
means that any of our employees could leave our employment at any time, with or without notice. We do not maintain “key person” insurance policies on
the lives of these individuals or the lives of any of our other employees. Our success also depends on our ability to continue to attract, retain and motivate
highly skilled junior, mid-level and senior managers as well as junior, mid-level and senior scientific and medical personnel.

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

As of February 1, 2021, we had 265 full-time employees. As our development, manufacturing and commercialization plans and strategies develop,

we have rapidly expanded our employee base and expect to add managerial, operational, sales, research and development, marketing, financial and other
personnel. Current and future growth imposes significant added responsibilities on members of management, including:

•
•

•

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

managing our internal development efforts effectively, including the clinical and FDA review process for our product candidates, while
complying with our contractual obligations to contractors and other third parties; and

improving our operational, financial and management controls, reporting systems and procedures.

Our future financial performance and our ability to commercialize our product candidates will depend, in part, on our ability to effectively manage

our growth, and our management may also have to divert a disproportionate amount of its attention away from day-to-day activities in order to devote a
substantial amount of time to managing these growth activities. Our ability to build our organization and manage our employees has also been affected by
the COVID-19 pandemic, as our staff are working from home, except for a limited number primarily working in our laboratories and manufacturing
facility. The effects of the stay-at-home orders and our work-from-home policies may negatively impact productivity, disrupt our business and delay our
development programs, regulatory and commercialization timelines, the magnitude of which will depend, in part, on the length and severity of the
restrictions and other limitations on our ability to conduct our business in the ordinary course.

We currently rely, and for the foreseeable future will continue to rely, in substantial part on certain independent organizations, advisors and

consultants. There can be no assurance that the services of independent organizations, advisors and consultants will continue to be available to us on a
timely basis when needed, or that we can find qualified replacements. We may also be subject to penalties or other liabilities if we mis-classify employees
as consultants. In addition, if we are unable to effectively manage our outsourced activities or if the quality or accuracy of the services provided by
consultants is compromised for any reason, our clinical trials may be extended, delayed or terminated, and we may not be able to obtain regulatory
approval of our product candidates or otherwise advance our business. There can be no assurance that we will be able to manage our existing consultants or
find other competent outside contractors and consultants on economically reasonable terms, or at all.

If we are not able to effectively expand our organization by hiring new employees and expanding our groups of consultants and contractors, we

may not be able to successfully implement the tasks necessary to further develop, manufacture and commercialize our product candidates and, accordingly,
may not achieve our research, development, manufacturing and commercialization goals.

We may form or seek additional strategic alliances or enter into additional licensing arrangements in the future, and we may not realize the benefits of
such alliances or licensing arrangements.

We may form or seek additional strategic alliances, create joint ventures or collaborations or enter into additional licensing arrangements with

third parties that we believe will complement or augment our development and commercialization efforts with respect to our product candidates and any
future product candidates that we may develop. Any of these relationships may require us to incur non-recurring and other charges, increase our near and
long-term expenditures, issue

53

Table of Contents

securities that dilute our existing stockholders or disrupt our management and business. In addition, we face significant competition in seeking appropriate
strategic partners and the negotiation process is time-consuming and complex. Moreover, we may not be successful in our efforts to establish a strategic
partnership or other alternative arrangements for our product candidates because they may be deemed to be at too early of a stage of development for
collaborative effort and third parties may not view our product candidates as having the requisite potential to demonstrate safety and efficacy. Any delays in
entering into new strategic partnership agreements related to our product candidates could delay the development and commercialization of our product
candidates in certain geographies for certain indications, which would harm our business prospects, financial condition and results of operations.

If we license products or acquire businesses, we may not be able to realize the benefit of such transactions if we are unable to successfully

integrate them with our existing operations and company culture. For instance, our agreements with Cellectis, Servier, Notch and SpringWorks require
significant research and development that may not result in the development and commercialization of product candidates. We cannot be certain that,
following a strategic transaction or license, we will achieve the results, revenue or specific net income that justifies such transaction.

We may not realize the benefits of acquired assets or other strategic transactions.

We actively evaluate various strategic transactions on an ongoing basis. We may acquire other businesses, products or technologies as well as

pursue joint ventures or investments in complementary businesses. The success of our strategic transactions, including our acquisition of CAR T cell assets
from Pfizer, licenses with Cellectis, Servier and Notch, joint venture with Overland Pharmaceuticals (CY) Inc. and any future strategic transactions
depends on the risks and uncertainties involved including:

•
•
•

•

•
•

•

unanticipated liabilities related to acquired companies or joint ventures;

difficulties integrating acquired personnel, technologies and operations into our existing business;

retention of key employees;

diversion of management time and focus from operating our business to management of strategic alliances or joint ventures or acquisition
integration challenges;

increases in our expenses and reductions in our cash available for operations and other uses;

disruption in or termination of our relationships with collaborators or suppliers as a result of such a transaction; and

possible write-offs or impairment charges relating to acquired businesses or joint ventures.

If any of these risks or uncertainties occur, we may not realize the anticipated benefit of any acquisition or strategic transaction.

Additionally, foreign acquisitions and joint ventures are subject to additional risks, including those related to integration of operations across
different cultures and languages, currency risks, potentially adverse tax consequences of overseas operations and the particular economic, political and
regulatory risks associated with specific countries. For instance, our joint venture with Overland Pharmaceuticals (CY) Inc. may face difficulties
manufacturing or delivering our licensed product candidates in China, Taiwan, South Korea or Singapore, which could prevent any development or
commercialization of our licensed product candidates in the region. The joint venture will also require significant financial support in the future by us or
third parties, and any future financing of the joint venture would increase our expenses or dilute our ownership in the joint venture.

Future acquisitions or dispositions could result in potentially dilutive issuances of our equity securities, the incurrence of debt, contingent

liabilities or amortization expenses or write-offs of goodwill, any of which could harm our financial condition.

We will need substantial additional financing to develop our products and implement our operating plans. If we fail to obtain additional financing, we
may be unable to complete the development and commercialization of our product candidates.

We expect to spend a substantial amount of capital in the development and manufacture of our product candidates. We will need substantial

additional financing to develop our products and implement our operating plans. In particular, we will require substantial additional financing to enable
commercial production of our products and initiate and complete registration

54

Table of Contents

trials for multiple products in multiple regions. Further, if approved, we will require significant additional amounts in order to launch and commercialize
our product candidates.

As of December 31, 2020, we had $1.0 billion in cash, cash equivalents and investments. Changing circumstances may cause us to consume

capital significantly faster than we currently anticipate, and we may need to spend more money than currently expected because of circumstances beyond
our control. We may also need to raise additional capital sooner than we currently anticipate if we choose to expand more rapidly than we presently plan. In
any event, we will require additional capital for the further development and commercialization of our product candidates, including funding our internal
manufacturing capabilities.

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 or commercialization of our product candidates or other research and development initiatives. Our license agreements may
also be terminated if we are unable to meet the payment obligations under the agreements. We could be required to seek collaborators for our 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 our 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.

Our internal computer systems, or those used by our CROs, collaborators or other contractors or consultants, may fail or suffer security breaches.

Our internal computer systems and those of our CROs, collaborators, and other contractors or consultants are vulnerable to damage from computer
viruses, unauthorized access, cybersecurity threats, and telecommunication and electrical failures. In addition, the COVID-19 pandemic has intensified our
dependence on information technology systems as many of our critical business activities are currently being conducted remotely. A successful cyberattack
could result in the theft or destruction of intellectual property, data, or other misappropriation of assets, financial loss or otherwise compromise our
confidential or proprietary information and disrupt our operations. Any failure to prevent or mitigate security breaches or improper access to, use of, or
disclosure of our clinical data or patients’ personal data could result in significant liability under state, federal, and international law and may cause a
material adverse impact to our reputation, affect our ability to conduct our clinical trials and potentially disrupt our business.

Cyberattacks are increasing in their frequency, sophistication and intensity, and have become increasingly difficult to detect. Cyberattacks could

include wrongful conduct by hostile foreign governments, industrial espionage, wire fraud and other forms of cyber fraud, the deployment of harmful
malware, denial-of-service, social engineering fraud or other means to threaten data security, confidentiality, integrity and availability. Although we devote
resources to protect our information systems, we realize that cyberattacks are a threat, and there can be no assurance that our efforts will prevent
information security breaches that would result in business, legal, financial or reputational harm to us, or would have a material adverse effect on our
results of operations and financial condition. In addition, failure to maintain effective internal accounting controls related to security breaches and
cybersecurity in general could impact our ability to produce timely and accurate financial statements and subject us to regulatory scrutiny. Any failure by
third-party providers to prevent or mitigate security breaches or improper access to or disclosure of such information could have similarly adverse
consequences for us.

Changes in funding for the FDA, the SEC 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 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 payment of user fees, statutory, regulatory and policy changes, and business disruptions, such as
those caused by the COVID-19 pandemic. Average review times at the agency have fluctuated in recent years as a result. In addition, government funding
of the SEC and 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

55

Table of Contents

years, 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. Further, future government
shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

Business disruptions could seriously harm our future revenue and financial condition and increase our costs and expenses.

In addition to the business disruptions caused by the COVID-19 pandemic or cybersecurity attacks described above, our operations, and those of

our CMOs, CROs, clinical trial sites and other contractors and consultants, could be subject to other disruptions, including those caused by earthquakes,
power shortages, telecommunications failures, water shortages, floods, hurricanes, typhoons, fires, extreme weather conditions, medical epidemics and
other natural or man-made disasters or business interruptions, for which we are predominantly self-insured. The occurrence of any of these business
disruptions could seriously harm our operations and financial condition and increase our costs and expenses.

Our ability to manufacture our product candidates could be disrupted if our operations or those of our suppliers are affected by a man-made or

natural disaster or other business interruption. Our corporate headquarters and manufacturing facility are located in California near major earthquake faults
and fire zones. The ultimate impact on us, our significant suppliers and our general infrastructure of being located near major earthquake faults and fire
zones and being consolidated in certain geographical areas is unknown, but our operations and financial condition could suffer in the event of a major
earthquake, fire or other natural disaster.

Our relationships with customers, physicians, and third-party payors are subject, directly or indirectly, to federal, state, local and foreign healthcare
fraud and abuse laws, false claims laws, health information privacy and security laws, and other healthcare laws and regulations. If we or our
employees, independent contractors, consultants, commercial partners and vendors violate these laws, we could face substantial penalties.

These laws may impact, among other things, our clinical research program, as well as our proposed and future sales, marketing and education

programs. In particular, the promotion, sales and marketing of healthcare items and services is subject to extensive laws and regulations designed to prevent
fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting,
marketing and promotion, sales commission, customer incentive and other business arrangements. We may also be subject to federal, state and foreign laws
governing the privacy and security of identifiable patient information. If our operations are found to be in violation of any of these laws that apply to us, we
may be subject to significant civil, criminal and administrative penalties.

European data collection is governed by restrictive regulations governing the use, processing, and cross-border transfer of personal information.

The collection and use of personal data in the European Union (EU) are governed by the General Data Protection Regulation (GDPR). The GDPR

imposes stringent requirements for controllers and processors of personal data, including, for example, more robust disclosures to individuals and a
strengthened individual data rights regime, shortened timelines for data breach notifications, limitations on retention of information, increased requirements
pertaining to special categories of data, such as health data, and additional obligations when we contract with third-party processors in connection with the
processing of the personal data. The GDPR also imposes strict rules on the transfer of personal data out of the European Union to the United States and
other third countries. In addition, the GDPR provides that EU member states may make their own further laws and regulations limiting the processing of
personal data, including genetic, biometric or health data.

The GDPR applies extraterritorially, and we may be subject to the GDPR because of our data processing activities that involve the personal data of

individuals located in the European Union, such as in connection with our EU clinical trials. Failure to comply with the requirements of the GDPR and the
applicable national data protection laws of the EU member states may result in fines of up to €20,000,000 or up to 4% of the total worldwide annual
turnover of the preceding financial year, whichever is higher, and other administrative penalties. GDPR regulations may impose additional responsibility
and liability in relation to the personal data that we process and we may be required to put in place additional mechanisms to ensure compliance with the
new data protection rules. This may be onerous and may interrupt or delay our development activities, and adversely affect our business, financial
condition, results of operations and prospects.

Additionally, California recently enacted legislation that has been dubbed the first “GDPR-like” law in the United States. Known as the California

Consumer Privacy Act (CPPA), it creates new individual privacy rights for consumers (as that word is broadly defined in the law) and places increased
privacy and security obligations on entities handling personal data of

56

Table of Contents

consumers or households. The CCPA requires covered companies to provide new disclosures to California consumers, provide such consumers new ways
to opt-out of certain sales of personal information, and allow for a new cause of action for data breaches. As our business progresses, the CCPA may
become applicable and significantly impact our business activities and exemplifies the vulnerability of our business to evolving regulatory environment
related to personal data and protected health information.

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of our product
candidates.

We face an inherent risk of product liability as a result of the clinical testing of our product candidates and will face an even greater risk if we

commercialize any products. For example, we may be sued if our product candidates cause or are perceived to cause injury or are found to be otherwise
unsuitable during clinical testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing,
defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability or a breach of warranties. Claims could also be asserted
under state consumer protection acts. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be
required to limit commercialization of our product candidates. Even successful defense would require significant financial and management resources.
Regardless of the merits or eventual outcome, liability claims may result in:

•
•

•
•
•

•
•

•
•

•
•
•

decreased demand for our product candidates;

injury to our reputation;

withdrawal of clinical trial participants;

initiation of investigations by regulators;

costs to defend the related litigation;

a diversion of management’s time and our resources;

substantial monetary awards to trial participants or patients;

product recalls, withdrawals or labeling, marketing or promotional restrictions;

loss of revenue;

exhaustion of any available insurance and our capital resources;

the inability to commercialize any product candidate; and

a decline in our share price.

Our inability to obtain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent

or inhibit the commercialization of products we develop, alone or with corporate collaborators. Our insurance policies may also have various exclusions,
and we may be subject to a product liability claim for which we have no coverage. While we have obtained and expect to obtain clinical trial insurance for
our clinical trials, we may have to pay amounts awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered
by our insurance, and we may not have, or be able to obtain, sufficient capital to pay such amounts. Even if our agreements with any future corporate
collaborators entitle us to indemnification against losses, such indemnification may not be available or adequate should any claim arise.

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

Under the Tax Act, as modified by the Coronavirus Aid, Relief, and Economic Security Act (CARES Act), federal net operating losses incurred in

tax years beginning after December 31, 2017, may be carried forward indefinitely, but the deductibility of such federal net operating losses in tax years
beginning after December 31, 2020, is limited to 80% of taxable income. It is uncertain if and to what extent various states will conform to the Tax Act or
the CARES Act. Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, and corresponding provisions of state law, if a
corporation undergoes an “ownership change” (generally defined as a greater than 50 percentage point change (by value) in the equity ownership of certain
stockholders over a rolling three-year period), the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax
attributes to offset its post-change income or taxes may be limited. As a result of our IPO in October 2018 and private placements and other transactions
that have occurred since our incorporation, we may have experienced an “ownership change”. We may also experience ownership changes in the future as a
result of subsequent shifts in our stock ownership. We anticipate incurring significant additional net losses for the foreseeable future, and our ability to
utilize net operating loss carryforwards associated with any such losses to offset future taxable income may be limited to the

57

Table of Contents

extent we incur future ownership changes. In addition, at the state level, there may be periods during which the use of net operating loss carryforwards is
suspended or otherwise limited, which could accelerate or permanently increase state taxes owed. For example, California recently imposed limits on the
usability of California state net operating losses to offset taxable income in tax years beginning after 2019 and before 2023. As a result, we may be unable
to use all or a material portion of our net operating loss carryforwards and other tax attributes, which could adversely affect our future cash flows.

Risks Related to Our Reliance on Third Parties

We rely and will continue to 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, we may not be able to obtain regulatory approval of or commercialize our product candidates.

We depend and will continue to depend upon independent investigators and collaborators, such as universities, medical institutions, CROs and

strategic partners to conduct our preclinical and clinical trials under agreements with us.

We negotiate budgets and contracts with CROs and study sites, which may result in delays to our development timelines and increased costs. We

will rely heavily on these third parties over the course of our clinical trials, and we control only certain aspects of their activities. Nevertheless, we are
responsible for ensuring that each of our studies is conducted in accordance with applicable protocol, legal, regulatory and scientific standards, and our
reliance on third parties does not relieve us of our regulatory responsibilities. We and these third parties are required to comply with good clinical practices
(GCPs), which are regulations and guidelines enforced by the FDA and comparable foreign regulatory authorities for product candidates in clinical
development. Regulatory authorities enforce these GCPs through periodic inspections of trial sponsors, principal investigators and trial sites. If we or any
of these third parties fail to comply with applicable GCP regulations, the clinical data generated in our clinical trials may be deemed unreliable and the
FDA or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. We
cannot assure you that, upon inspection, such regulatory authorities will determine that any of our clinical trials comply with the GCP regulations. In
addition, our clinical trials must be conducted with biologic product produced under cGMPs and will require a large number of test patients. Our failure or
any failure by these third parties to comply with these regulations 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 federal or state fraud and abuse
or false claims laws and regulations or healthcare privacy and security laws.

Any third parties conducting our clinical trials are and will not be our employees and, except for remedies available to us under our agreements

with such third parties, we cannot control whether or not 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 studies or other drug 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 trial sites, or any CRO that we may use in the future, terminates, we may not be able to enter into arrangements

with alternative trial sites or CROs or do so on commercially reasonable terms. Switching or adding third parties to conduct our clinical trials involves
substantial cost and requires extensive management time and focus. In addition, there is a natural transition period when a new third party commences
work. As a result, delays occur, which can materially impact our ability to meet our desired clinical development timelines.

We rely on third parties to manufacture our clinical product supplies, and we may have to rely on third parties to produce and process our product
candidates, if approved.

Our product candidates are manufactured in the United States by our CMOs, and we manage all other aspects of the supply, including planning,

CMO oversight, disposition and distribution logistics. In the past, Servier was responsible for UCART19 manufacturing, and experienced UCART19
supply issues that limited its ability to recruit new patients in the past. There can be no assurance that we will not experience supply or manufacturing
issues in the future.

58

Table of Contents

While we are in the process of developing our own manufacturing facility for cell therapies, we must currently rely on outside vendors to

manufacture supplies and process our product candidates. We do not have long-term agreements in place with CMOs for the manufacture of our cell
therapies or of ALLO-647. If we are unable to contract with CMOs on acceptable terms or at all, our clinical development program would be delayed and
our business would be significantly harmed.

We have not yet caused our product candidates to be manufactured or processed on a commercial scale and may not be able to achieve
manufacturing and processing and may be unable to create an inventory of mass-produced, off-the-shelf product to satisfy demands for any of our product
candidates.

We do not yet have sufficient information to reliably estimate the cost of the commercial manufacturing and processing of our product candidates,

and the actual cost to manufacture and process our product candidates could materially and adversely affect the commercial viability of our product
candidates. As a result, we may never be able to develop a commercially viable product.

In addition, our anticipated reliance on a limited number of third-party manufacturers exposes us to the following risks:

•

•

•

•

•

•

•

We may be unable to identify manufacturers on acceptable terms or at all because the number of potential manufacturers is limited and the
FDA may have questions regarding any replacement contractor. This may require new testing and regulatory interactions. In addition, a
new manufacturer would have to be educated in, or develop substantially equivalent processes for, production of our products after receipt
of FDA questions, if any.

Our third-party manufacturers might be unable to timely formulate and manufacture our product or produce the quantity and quality
required to meet our clinical and commercial needs, if any.

Contract manufacturers may not be able to execute our manufacturing procedures appropriately.

Manufacturers are subject to ongoing periodic unannounced inspection by the FDA, the Drug Enforcement Administration and
corresponding state agencies to ensure strict compliance with cGMP and other government regulations and corresponding foreign
standards. We do not have control over third-party manufacturers’ compliance with these regulations and standards.

We may not own, or may have to share, the intellectual property rights to any improvements made by our third-party manufacturers in the
manufacturing process for our products.

Our future contract manufacturers may not perform as agreed or may not remain in the contract manufacturing business for the time
required to supply our clinical trials or to successfully produce, store and distribute our products.

Our third-party manufacturers could breach or terminate their agreement with us.

Our contract manufacturers would also be subject to the same risks we face in developing our own manufacturing capabilities, as described above.

For instance, our CMOs may be required to shutdown in response to the spread of COVID-19. In addition, our CMOs have certain responsibilities for
storage of raw materials and in the past have lost or failed to adequately store our raw materials. Any additional or future damage or loss of raw materials
could materially impact our ability to manufacture and supply our product candidates. Each of these risks could delay our clinical trials, the approval, if any
of our product candidates by the FDA or the commercialization of our product candidates or result in higher costs or deprive us of potential product
revenue. In addition, we will rely on third parties to perform release tests on our product candidates prior to delivery to patients. If these tests are not
appropriately done and test data are not reliable, patients could be put at risk of serious harm.

We rely on donors of T cells to manufacture our product candidates, and if we do not obtain an adequate supply of T cells from qualified donors,
development of those product candidates may be adversely impacted.

Unlike autologous CAR T companies, we are reliant on receiving healthy donor material to manufacture our product candidates. Healthy donor T

cells vary in type and quality, and this variation makes producing standardized product candidates more difficult and makes the development and
commercialization pathway of those product candidates more uncertain. We have developed a screening process designed to enhance the quality and
consistency of T cells used in the manufacture of our CAR T cell product candidates, but our screening process may fail to identify suitable donor material
and we may discover failures with the material after production. We may also have to update our specifications for new risks that may emerge, such as to
screen for new viruses.

59

Table of Contents

We have strict specifications for donor material, which include specifications required by regulatory authorities. If we are unable to identify and

obtain donor material that satisfy specifications, agree with regulatory authorities on appropriate specifications, or address variability in donor T cells, there
may be inconsistencies in the product candidates we produce or we may be unable to initiate or continue ongoing clinical trials on the timelines we expect,
which could harm our reputation and adversely impact our business and prospects.

In addition, vendors have in the past been unable to secure donor material during the COVID-19 pandemic due to government restrictions on

business activity and travel. While we have donor material on hand, and our vendors are currently able to provide us with donor material, if the COVID-19
pandemic continues and our vendors are unable to secure donor material, we may no longer have sufficient donor material to manufacture our product
candidates.

Cell-based therapies rely on the availability of specialty raw materials, which may not be available to us on acceptable terms or at all.

Our product candidates require many specialty raw materials, including viral vectors that deliver the CAR sequence and electroporation
technology, some of which are manufactured by small companies with limited resources and experience to support a commercial product, and the suppliers
may not be able to deliver raw materials to our specifications. We do not have contracts with many of the suppliers, and we may not be able to contract
with them on acceptable terms, or at all. Many suppliers have curtailed their operations during the COVID-19 pandemic or focused their operations on
supporting COVID-19 therapies and vaccines, and our ability to source raw materials has been impacted. Accordingly, we may experience delays in
receiving, or fail to secure entirely, key raw materials to support clinical or commercial manufacturing. Certain raw materials also require third-party
testing, and some of the testing service companies may not have capacity or be able to conduct the testing that we request.

In addition, many of our suppliers normally support blood-based hospital businesses and generally do not have the capacity to support commercial

products manufactured under cGMP by biopharmaceutical firms. The suppliers may be ill-equipped to support our needs, especially in non-routine
circumstances like an FDA inspection or medical crisis, such as widespread contamination. We also face competition for supplies from other cell therapy
companies. Such competition may make it difficult for us to secure raw materials or the testing of such materials on commercially reasonable terms or in a
timely manner.

Some raw materials are currently available from a single supplier, or a small number of suppliers. We cannot be sure that these suppliers will

remain in business or that they will not be purchased by one of our competitors or another company that is not interested in continuing to produce these
materials for our intended purpose. In addition, the lead time needed to establish a relationship with a new supplier can be lengthy, and we may experience
delays in meeting demand in the event we must switch to a new supplier. The time and effort to qualify a new supplier, including to meet any regulatory
requirements for such qualification, could result in additional costs, diversion of resources or reduced manufacturing yields, any of which would negatively
impact our operating results. Further, we may be unable to enter into agreements with a new supplier on commercially reasonable terms, which could have
a material adverse impact on our business.

If we or our third-party suppliers use hazardous, non-hazardous, biological or other materials in a manner that causes injury or violates applicable
law, we may be liable for damages.

Our research and development activities involve the controlled use of potentially hazardous substances, including chemical and biological

materials. We and our suppliers are subject to federal, state and local laws and regulations in the United States governing the use, manufacture, storage,
handling and disposal of medical and hazardous materials. Although we believe that we and our suppliers’ procedures for using, handling, storing and
disposing of these materials comply with legally prescribed standards, we and our suppliers cannot completely eliminate the risk of contamination or injury
resulting from medical or hazardous materials. As a result of any such contamination or injury, we may incur liability or local, city, state or federal
authorities may curtail the use of these materials and interrupt our business operations. In the event of an accident, we could be held liable for damages or
penalized with fines, and the liability could exceed our resources. We do not have any insurance for liabilities arising from medical or hazardous materials.
Compliance with applicable environmental laws and regulations is expensive, and current or future environmental regulations may impair our research,
development and production efforts, which could harm our business, prospects, financial condition or results of operations.

Risks Related to Government Regulation

The FDA regulatory approval process is lengthy and time-consuming, and we may experience significant delays in the clinical development and
regulatory approval of our product candidates.

60

Table of Contents

The research, testing, manufacturing, labeling, approval, selling, import, export, marketing, and distribution of drug products, including biologics,

are subject to extensive regulation by the FDA and other regulatory authorities in the United States. We are not permitted to market any biological drug
product in the United States until we receive approval of a biologics license application (BLA) 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 the product candidate’s safety and effectiveness for each desired indication. The BLA must also include significant information
regarding the chemistry, manufacturing and controls for the product.

We expect the novel nature of our product candidates to create further challenges in obtaining regulatory approval. For example, the FDA has

limited experience with commercial development of allogeneic T cell therapies for cancer. We may also request regulatory approval of future CAR-based
product candidates by target, regardless of cancer type or origin, which the FDA may have difficulty accepting if our clinical trials only involved cancers of
certain origins. 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 licensure. The opinion of the Advisory Committee, although not binding, may have a significant impact on our ability to obtain
licensure of the product candidates based on the completed clinical trials, as the FDA often adheres to the Advisory Committee’s recommendations.
Accordingly, the regulatory approval pathway for our product candidates may be uncertain, complex, expensive and lengthy, and approval may not be
obtained.

We may also experience delays in completing planned clinical trials for a variety of reasons, including delays related to:

•
•

•

•

•

•

•

•

•
•
•

obtaining regulatory authorization to begin a trial, if applicable;

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

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

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

obtaining regulatory and other approvals to modify the conduct of a clinical trial;

recruiting suitable patients to participate in a trial;

having patients complete a trial, including having patients enrolled in clinical trials dropping out of the trial before the product candidate is
manufactured and returned to the site, or return for post-treatment follow-up;

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

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

adding new clinical trial sites; or

manufacturing sufficient quantities of qualified materials under cGMPs and delivering product candidates for use in clinical trials.

We could also encounter delays if physicians encounter unresolved ethical issues associated with enrolling patients in clinical trials of our product

candidates in lieu of prescribing existing treatments that have established safety and efficacy profiles. Further, a clinical trial may be suspended or
terminated by us, the IRBs for the institutions in which such trials are being conducted or by 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, lack of adequate
funding to continue the clinical trial, or based on a recommendation by the Data Safety Monitoring Committee. The FDA’s review of our data of our
ongoing clinical trials may, depending on the data, also result in the delay, suspension or termination of one or more of our clinical trials, which would also
delay or prevent the initiation of our other planned clinical trials. If we experience termination of, or delays in the completion of, any clinical trial of our
product candidates, the commercial prospects for our product candidates will be harmed, and our ability to generate product revenue will be delayed. In
addition, any delays in completing our 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.

Many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may ultimately lead to the denial of

regulatory approval of our product candidates.

61

Table of Contents

We expect the product candidates we develop will be regulated as biological products, or biologics, and therefore they may be subject to competition
sooner than anticipated.

The Biologics Price Competition and Innovation Act of 2009 (BPCIA) was enacted as part of the Patient Protection and Affordable Care Act, as
amended by the Health Care and Education Reconciliation Act of 2010 (collectively, the Affordable Care Act) to establish an abbreviated pathway for the
approval of biosimilar and interchangeable biological products. The regulatory pathway establishes legal authority for the FDA to review and approve
biosimilar biologics, including the possible designation of a biosimilar as “interchangeable” based on its similarity to an approved biologic. Under the
BPCIA, an application for a biosimilar product cannot be approved by the FDA until 12 years after the reference product was approved under a BLA. The
law is complex and is still being interpreted and implemented by the FDA. As a result, its ultimate impact, implementation, and meaning are subject to
uncertainty and could have a material adverse effect on the future commercial prospects for our biological products.

We believe that any of the product candidates we develop that is approved in the United States as a biological product under a BLA should qualify

for the 12-year period of exclusivity. However, there is a risk that this exclusivity could be shortened due to congressional action or otherwise, or that the
FDA will not consider the subject product candidates to be reference products for competing products, potentially creating the opportunity for generic
competition sooner than anticipated. Moreover, the extent to which a biosimilar, once approved, will be substituted for any one of the reference products in
a way that is similar to traditional generic substitution for non-biological products is not yet clear, and will depend on a number of marketplace and
regulatory factors that are still developing.

The regulatory landscape that will govern our product candidates is uncertain; regulations relating to more established gene therapy and cell therapy
products are still developing, and changes in regulatory requirements could result in delays or discontinuation of development of our product
candidates or unexpected costs in obtaining regulatory approval.

Because we are developing novel CAR T cell immunotherapy product candidates that are unique biological entities, the regulatory requirements

that we will be subject to are not entirely clear. Even with respect to more established products that fit into the categories of gene therapies or cell therapies,
the regulatory landscape is still developing. For example, regulatory requirements governing gene therapy products and cell therapy products have changed
frequently and may continue to change in the future. Moreover, there is substantial, and sometimes uncoordinated, overlap in those responsible for
regulation of existing gene therapy products and cell therapy products. For example, in the United States, the FDA has established the Office of Tissues and
Advanced Therapies (OTAT), formerly known as the Office of Cellular, Tissue and Gene Therapies (OCTGT), within its Center for Biologics Evaluation
and Research (CBER) to consolidate the review of gene therapy and related products, and the Cellular, Tissue and Gene Therapies Advisory Committee to
advise CBER on its review. Gene therapy clinical trials are also subject to review and oversight by an institutional biosafety committee (IBC), a local
institutional committee that reviews and oversees basic and clinical research conducted at the institution participating in the clinical trial. Although the
FDA decides whether individual gene therapy protocols may proceed, review process and determinations of other reviewing bodies can impede or delay the
initiation of a clinical study, even if the FDA has reviewed the study and approved its initiation. Conversely, the FDA can place an IND application on
clinical hold even if such other entities have provided a favorable review. Furthermore, each clinical trial must be reviewed and approved by an
independent IRB at or servicing each institution at which a clinical trial will be conducted. In addition, adverse developments in clinical trials of gene
therapy products conducted by others may cause the FDA or other regulatory bodies to change the requirements for approval of any of our product
candidates.

Complex regulatory environments exist in other jurisdictions in which we might consider seeking regulatory approvals for our product candidates,

further complicating the regulatory landscape. For example, in the EU a special committee called the Committee for Advanced Therapies (CAT) was
established within the EMA in accordance with Regulation (EC) No 1394/2007 on advanced-therapy medicinal products (ATMPs) to assess the quality,
safety and efficacy of ATMPs, and to follow scientific developments in the field. ATMPs include gene therapy products as well as somatic cell therapy
products and tissue engineered products. In this regard, on May 28, 2014, the EMA issued a recommendation that UCART19 be considered a gene therapy
product under Regulation (EC) No 1394/2007 on ATMPs. We believe our other product candidates may receive a similar recommendation.

These various regulatory review committees and advisory groups and new or revised guidelines that they promulgate from time to time may
lengthen the regulatory review process, require us to perform additional studies, increase our development costs, lead to changes in regulatory positions and
interpretations, delay or prevent approval and commercialization of our product candidates or lead to significant post-approval limitations or restrictions.
Because the regulatory landscape for our CAR T cell immunotherapy product candidates is new, we may face even more cumbersome and complex
regulations than those emerging for gene therapy products and cell therapy products. Furthermore, even if our product candidates obtain

62

Table of Contents

required regulatory approvals, such approvals may later be withdrawn as a result of changes in regulations or the interpretation of regulations by applicable
regulatory agencies.

Delay or failure to obtain, or unexpected costs in obtaining, the regulatory approval necessary to bring a potential product to market could

decrease our ability to generate sufficient product revenue to maintain our business.

The FDA may disagree with our regulatory plan and we may fail to obtain regulatory approval of our CAR T cell product candidates.

If and when our ongoing and planned Phase 1 clinical trials are completed and, assuming positive data, we expect to advance to potential
registrational trials. The general approach for FDA approval of a new biologic or drug is for the sponsor to provide dispositive data from two well-
controlled, Phase 3 clinical studies of the relevant biologic or drug in the relevant patient population. Phase 3 clinical studies typically involve hundreds of
patients, have significant costs and take years to complete. We expect registrational trials for ALLO-501A and ALLO-715 to be designed to evaluate the
efficacy of the product candidate in an open-label, non-comparative, two-stage, pivotal, multicenter, single-arm clinical trial in patients who have exhausted
available treatment options. If the results are sufficiently compelling, we intend to discuss with the FDA submission of a BLA for the relevant product
candidate. However, we do not have any agreement or guidance from the FDA that our regulatory development plans will be sufficient for submission of a
BLA. For example, the FDA may require that we conduct a comparative trial against an approved therapy including potentially an approved autologous T
cell therapy, which would significantly delay our development timelines and require substantially more resources. In addition, the FDA may only allow us
to evaluate patients that have failed or who are ineligible for autologous therapy, which are extremely difficult patients to treat and patients with advanced
and aggressive cancer, and our product candidates may fail to improve outcomes for such patients.

Given the molecular similarities between ALLO-501 and ALLO-501A, we may have additional difficulties progressing any clinical trial of

ALLO-501A, if emerging data from the clinical trial of ALLO-501 have safety or other issues.

The FDA may grant accelerated approval for our product candidates and, as a condition for accelerated approval, the FDA may require a sponsor
of a drug or biologic receiving accelerated approval to perform post-marketing studies to verify and describe the predicted effect on irreversible morbidity
or mortality or other clinical endpoint, and the drug or biologic may be subject to withdrawal procedures by the FDA that are more accelerated than those
available for regular approvals. We believe our accelerated approval strategy is warranted given the limited alternatives for patients with R/R cancers, but
the FDA may ultimately require a Phase 3 clinical trial prior to approval, particularly since our product candidates represent a novel treatment. In addition,
the standard of care may change with the approval of new products in the same indications that we are studying. This may result in the FDA or other
regulatory agencies requesting additional studies to show that our product candidate is superior to the new products.

Our clinical trial results may also not support approval. In addition, our product candidates could fail to receive regulatory approval for many

reasons, including the following:

•

•

•

•

•
•

•

•

the FDA or comparable foreign regulatory authorities may disagree with the design or implementation of our clinical trials;

we may be unable to demonstrate to the satisfaction of the FDA or comparable foreign regulatory authorities that our product candidates are
safe and effective for any of their proposed indications;

the results of clinical trials may not meet the level of statistical significance required by the FDA or comparable foreign regulatory
authorities for approval, including due to the heterogeneity of patient populations;

we may be unable to demonstrate that our product candidates’ clinical and other benefits outweigh their safety risks;

the FDA or comparable foreign regulatory authorities may disagree with our interpretation of data from preclinical studies or clinical trials;

the data collected from clinical trials of our product candidates may not be sufficient to the satisfaction of the FDA or comparable foreign
regulatory authorities to support the submission of a BLA or other comparable submission in foreign jurisdictions or to obtain regulatory
approval in the United States or elsewhere;

the FDA or comparable foreign regulatory authorities will review our manufacturing process and inspect our commercial manufacturing
facility and may not approve our manufacturing process or facility; and

the approval policies or regulations of the FDA or comparable foreign regulatory authorities may significantly change in a manner
rendering our clinical data insufficient for approval.

We may be unable to obtain regulatory approval for ALLO-647 in a timely manner or at all, which could delay any approval or commercialization of
our allogeneic T cell product candidates.

As we are concurrently developing ALLO-647 to be used as part of the lymphodepletion regimen for our allogeneic CAR T cell product

candidates, mapping a path for dual approval of ALLO-647 and any of our CAR T cell product candidates and coordinating concurrent review with
different divisions of the FDA create additional regulatory uncertainty for us and may delay the development of our product candidates. We expect the
Center for Drug Evaluation and Research division of the FDA to exercise authority over the regulatory approval of ALLO-647 while the CBER division
will oversee the regulatory approval of our allogeneic CAR T cell product candidates.

In addition, we expect regulatory authorities will require us to demonstrate the safety of ALLO-647 and its contribution to the overall benefit to

risk ratio of the lymphodepletion regimen, including through a cohort of patients that do not receive ALLO-647. If we are unable to meet any of the
requirements of the regulatory authorities, we may be required to conduct additional clinical studies. We cannot be certain we will be able to successfully
obtain regulatory approval of ALLO-647 in a timely manner or at all. Any delays to ALLO-647 approval could delay any approval or commercialization of
our allogeneic CAR T cell product candidates.

We plan to seek orphan drug designation for some or all of our product candidates across various indications, but we may be unable to obtain such
designations or to maintain the benefits associated with orphan drug designation, including market exclusivity, which may cause our revenue, if any, to
be reduced.

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic intended to treat a rare disease or condition, defined as a

disease or condition with a patient population of fewer than 200,000 in the United States, or a patient population greater than 200,000 in the United States
when there is no reasonable expectation that the cost of developing and making available the drug or biologic in the United States will be recovered from
sales in the United States for that drug or biologic. In order to obtain orphan drug designation, the request must be made before submitting a BLA. In the
United States, 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. After the FDA grants orphan drug designation, the generic identity of the drug and its potential orphan use are disclosed
publicly by the FDA. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.

If a product that has orphan drug designation subsequently receives the first FDA approval of that particular product for the disease for which it

has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications, including a
BLA, to market the same biologic (meaning, a product with the same principal molecular structural features) for the same indication for seven years, except
in limited circumstances such as a showing of clinical superiority to the product with orphan drug exclusivity or if FDA finds that the holder of the orphan
drug exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or
condition for which the drug was designated. As a result, even if one of our product candidates receives orphan exclusivity, the FDA can still approve other
biologics that do not have the same principal molecular structural features for use in treating the same indication or disease or the same biologic for a
different indication or disease during the exclusivity period. Furthermore, the FDA can waive orphan exclusivity if we are unable to manufacture sufficient
supply of our product or if a subsequent applicant demonstrates clinical superiority over our product.

We plan to seek orphan drug designation for some or all of our product candidates in specific orphan indications in which there is a medically

plausible basis for the use of these products. Even if we obtain orphan drug designation, exclusive marketing rights in the United States may be limited if
we seek approval for an indication broader than the orphan designated indication and may be lost if the FDA later determines that the request for
designation was materially defective or if we are unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or
condition, or if a subsequent applicant demonstrates clinical superiority over our products, if approved. In addition, although we may seek orphan drug
designation for other product candidates, we may never receive such designations.

Negative public opinion and increased regulatory scrutiny of genetic research and therapies involving gene editing may damage public perception of
our product candidates or adversely affect our ability to conduct our business or obtain regulatory approvals for our product candidates.

The gene-editing technologies that we use are novel. Public perception may be influenced by claims that gene editing is unsafe, and products
incorporating gene editing may not gain the acceptance of the public or the medical community. In particular, our success will depend upon physicians
specializing in our targeted diseases prescribing our product candidates as treatments in lieu of, or in addition to, existing, more familiar, treatments for
which greater clinical data may be available. Any increase in negative perceptions of gene editing may result in fewer physicians prescribing our treatments
or may reduce the

64

Table of Contents

willingness of patients to utilize our treatments or participate in clinical trials for our product candidates. In addition, given the novel nature of gene-editing
and cell therapy technologies, governments may place import, export or other restrictions in order to retain control or limit the use of the technologies. For
instance, any limits on exporting certain of our technology to China may adversely affect Allogene Overland Biopharm (CY) Limited (Allogene Overland),
a joint venture established by us and Overland Pharmaceuticals (CY) Inc. Increased negative public opinion or more restrictive government regulations
either in the United States or internationally, would have a negative effect on our business or financial condition and may delay or impair the development
and commercialization of our product candidates or demand for such product candidates.

Even if we obtain regulatory approval of our product candidates, the products may not gain market acceptance among physicians, patients, hospitals,
cancer treatment centers and others in the medical community.

The use of engineered T cells as a potential cancer treatment is a recent development and may not become broadly accepted by physicians,

patients, hospitals, cancer treatment centers and others in the medical community. We expect physicians in the large bone marrow transplant centers to be
particularly important to the market acceptance of our products and we may not be able to educate them on the benefits of using our product candidates for
many reasons. For example, certain of the product candidates that we will be developing target a cell surface marker that may be present on cancer cells as
well as non-cancerous cells. It is possible that our product candidates may kill these non-cancerous cells, which may result in unacceptable side effects,
including death. Additional factors will influence whether our product candidates are accepted in the market, including:

•
•

•
•

•
•

•
•
•

•

•

•

the clinical indications for which our product candidates are approved;

physicians, hospitals, cancer treatment centers and patients considering our product candidates as a safe and effective treatment;

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

the prevalence and severity of any side effects;

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

limitations or warnings contained in the labeling approved by the FDA;

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

the cost of treatment in relation to alternative treatments;

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

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

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

the effectiveness of our sales and marketing efforts.

If our product candidates are approved but fail to achieve market acceptance among physicians, patients, hospitals, cancer treatment centers or

others in the medical community, we will not be able to generate significant revenue. 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.

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

Successful sales of our product candidates, if approved, depend on the availability of coverage and adequate reimbursement from third-party

payors including governmental healthcare programs, such as Medicare and Medicaid, managed care organizations and commercial payors, among others.
Significant uncertainty exists as to the coverage and reimbursement status of any product candidates for which we obtain regulatory approval. In addition,
because our product candidates represent new approaches to the treatment of cancer, we cannot accurately estimate the potential revenue from our product
candidates.

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. Obtaining coverage and adequate reimbursement from third-party payors is critical to new product acceptance.

65

Table of Contents

The marketability of any product candidates for which we receive regulatory approval for commercial sale may suffer if government and other
third-party payors fail to provide coverage and adequate reimbursement. We expect downward pressure on pharmaceutical pricing to continue. Further,
coverage policies and third-party reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or
more products for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

The advancement of healthcare reform may negatively impact our ability to sell our product candidates, if approved, profitably.

Third-party payors, whether domestic or foreign, or governmental or commercial, are developing increasingly sophisticated methods of
controlling healthcare costs. In both the United States and certain foreign jurisdictions, there have been a number of legislative and regulatory changes to
the health care system that could impact our ability to sell our product candidates, if approved, profitably. In particular, in 2010 the Affordable Care Act
was enacted. The Affordable Care Act and its implementing regulations, among other things, revised the methodology by which rebates owed by
manufacturers to the state and federal government for covered outpatient drugs and certain biologics, including our product candidates, under the Medicaid
drug rebate program are calculated, increased the minimum Medicaid rebates owed by most manufacturers under the Medicaid drug rebate program,
extended the Medicaid drug rebate program to utilization of prescriptions of individuals enrolled in Medicaid managed care organizations, subjected
manufacturers to new annual fees and taxes for certain branded prescription drugs, and provided incentives to programs that increase the federal
government’s comparative effectiveness research. Additionally, the Affordable Care Act allowed states to implement expanded eligibility criteria for
Medicaid programs, imposed a new Medicare Part D coverage gap discount program, expanded the entities eligible for discounts under the Public Health
Service pharmaceutical pricing program and implemented a new Patient-Centered Outcomes Research Institute. There have been legal and political
challenges to certain aspects of the Affordable Care Act. The U.S. Supreme Court is currently reviewing the constitutionality of the Affordable Care Act,
but it is unknown when a decision will be reached. It is unclear how the Supreme Court ruling, other such litigation, and the healthcare reform measures of
the Biden administration will impact the Affordable Care Act and our business.

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. The implementation of cost containment measures or other healthcare
reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our products. Such reforms could have an adverse effect
on anticipated revenue from product candidates that we may successfully develop and for which we may obtain regulatory approval and may affect our
overall financial condition and ability to develop product candidates.

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

which may adversely affect our future profitability.

Risks Related to Our Intellectual Property

We depend on intellectual property licensed from third parties and termination 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.

We depend substantially on our license agreements with Pfizer, Servier and Cellectis. These licenses may be terminated upon certain conditions.

Any termination of these licenses could result in the loss of significant rights and could harm our ability to commercialize our product candidates. For
example, we are dependent on our license with Cellectis for gene-editing technology that is necessary to produce our engineered T cells. In addition, we are
reliant on Servier in-licensing from Cellectis some of the intellectual property rights they are licensing to us, including certain intellectual property rights
relating to ALLO-501 and ALLO-501A. To the extent these licensors fail to meet their obligations under their license agreements, which we are not in
control of, we may lose the benefits of our license agreements with these licensors. In the future, we may also enter into additional license agreements that
are material to the development of our product candidates.

Disputes may also arise between us and our licensors regarding intellectual property subject to a license agreement, including those related to:

•

•

•

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

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

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

66

Table of Contents

•

•

our diligence obligations with respect to the use of the licensed technology in relation to our development and commercialization of our
product candidates, and what activities satisfy those diligence obligations; and

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

If disputes over intellectual property that we have licensed, or license in the future, prevent or impair our ability to maintain our current licensing

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

We are generally also subject to all of the same risks with respect to protection of intellectual property that we license, as we are for intellectual
property that we own, which are described below. If we or our licensors fail to adequately protect this intellectual property, our ability to commercialize
products could suffer.

If our efforts to protect the proprietary nature of the intellectual property related to our technologies are not adequate, we may not be able to compete
effectively in our market.

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

technologies. Any disclosure to or misappropriation by third parties of our confidential proprietary information could enable competitors to quickly
duplicate or surpass our technological achievements, thus eroding our competitive position in our market.

We have an exclusive collaboration with Servier to develop and commercialize certain anti-CD19 allogeneic T cell product candidates, including

ALLO-501A, and we hold the commercial rights to these product candidates in the United States. We also have an exclusive worldwide license from
Cellectis to its TALEN gene-editing technology for the development of allogeneic T cell product candidates directed against 15 different cancer antigens.
Our collaboration with Servier gives us access to TALEN gene-editing technology for all product candidates under the Servier Agreement. Certain
intellectual property which is covered by these agreements may have been developed with funding from the U.S. government. If so, our rights in this
intellectual property may be subject to certain research and other rights of the government.

Additional patent applications have been filed, and we anticipate additional patent applications will be filed, both in the United States and in other

countries, as appropriate. However, we cannot predict:

•
•

•

•

if and when patents will issue;

the 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 or not others will obtain patents claiming aspects similar to those covered by our patents and patent applications; or

whether we will need to initiate litigation or administrative proceedings which may be costly whether we win or lose.

Composition of matter patents for biological and pharmaceutical products such as CAR-based product candidates often provide a strong 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
that the claims in our pending patent applications covering composition of matter of our product candidates will be considered patentable by the United
States Patent and Trademark Office (USPTO) or by patent offices in foreign countries, or that the claims in any of our issued patents will be considered
valid and enforceable by courts in the United States or foreign countries. Method of use patents protect the use of a product for the specified method. 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.” 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 involves complex legal and scientific questions and can be uncertain. The

patent applications that we own or in-license may fail to result in issued patents with claims that cover our product candidates or uses thereof in the United
States or in other foreign countries. Even if the patents do successfully issue, third parties may challenge the patentability, validity, enforceability or scope
thereof, for example through inter partes review (IPR) post-grant review or ex parte reexamination before the USPTO or oppositions and other comparable
proceedings in foreign jurisdictions, which may result in such patents being cancelled, narrowed, invalidated or held

67

Table of Contents

unenforceable. 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 patents and
patent applications we hold with respect to our product candidates is threatened, it could dissuade companies from collaborating with us to develop, and
threaten our ability to commercialize, our product candidates. Further, if we encounter delays in our clinical trials, the period of time during which we
could market our product candidates under patent protection would be reduced. United States patent applications containing or that at any time contained a
claim not entitled to a priority date before March 16, 2013 are subject to the “first to file” system implemented by the America Invents Act (2011).

This first to file system will require us to be cognizant going forward of the time from invention to filing of a patent application. Since patent

applications in the United States 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. Furthermore, for United States 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. For United States applications containing a claim not entitled to priority before March
16, 2013, there is a greater level of uncertainty in the patent law in view of the passage of the America Invents Act, which brought into effect significant
changes to the United States patent laws, including new procedures for challenging patent applications and issued patents.

Confidentiality agreements with employees, Allogene Overland 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 proprietary

know-how that is not patentable, processes for which patents are difficult to enforce and any other elements of our product discovery and development
processes that involve proprietary know-how, information or technology that is not covered by patents. Trade secrets, however, may be difficult to protect.
Although we require all of our employees to assign their inventions to us, and require all of our employees and key consultants who have access to our
proprietary know-how, information, or technology to enter into confidentiality agreements, we cannot be certain that our trade secrets and other
confidential proprietary information will not be disclosed or that competitors will not otherwise gain access to our trade secrets or independently develop
substantially equivalent information and techniques. 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 United States. For example, we plan to transfer technology to Allogene Overland in certain developing countries, and
we cannot be certain that we or Allogene Overland will be able to protect or enforce any proprietary rights in these countries. As a result, we may
encounter significant problems in protecting and defending our intellectual property both in the United States and abroad. If we are unable to prevent
unauthorized material disclosure of our intellectual property to third parties, we will 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.

Third-party claims of intellectual property infringement may prevent or delay our product discovery and development efforts and our ability to
commercialize our product candidates.

Our commercial success depends in part on our avoiding infringement of the patents and proprietary rights of third parties. There is a substantial

amount of litigation involving patents and other intellectual property rights in the biotechnology and pharmaceutical industries. Numerous U.S. and foreign
issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we are developing our product candidates. As
the biotechnology and pharmaceutical industries expand 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.

Third parties may assert that we infringe their patents or are otherwise employing their proprietary technology without authorization and may sue

us. We are aware of several U.S. patents held by third parties relating to certain CAR compositions of matter and their methods of use. Generally,
conducting clinical trials and other development activities in the United States is not considered an act of infringement. If and when any of our product
candidates is approved by the FDA, third parties may then seek to enforce their patents by filing a patent infringement lawsuit against us. Patents issued in
the United States by law enjoy a presumption of validity that can be rebutted only with evidence that is “clear and convincing,” a heightened standard of
proof. We may not be able to prove in litigation that any patent enforced against us is invalid.

Additionally, there may be third-party patents of which we are currently unaware with claims to materials, formulations, methods of manufacture
or methods for treatment related to the use or manufacture of our product candidates. Because patent applications can take many years to issue, there may
be currently pending patent applications which may later result in issued patents that our product candidates may be alleged to infringe. In addition, third
parties may obtain patents in

68

Table of Contents

the future and claim that use of our technologies infringes upon these patents. If any third-party patents were held by a court of competent jurisdiction to
cover the manufacturing process of our product candidates, constructs or molecules used in or formed during the manufacturing process, or any final
product itself, the holders of any such patents may be able to block our ability to commercialize the product candidate unless we obtained a license under
the applicable patents, or until such patents expire or they are finally determined to be held not infringed, unpatentable, invalid or unenforceable. Similarly,
if any third-party patent were held by a court of competent jurisdiction to cover aspects of our formulations, processes for manufacture or methods of use,
including combination therapy or patient selection methods, the holders of any such patent may be able to block our ability to develop and commercialize
the product candidate unless we obtained a license or until such patent expires or is finally determined to be held not infringed, unpatentable, invalid or
unenforceable. In either case, 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, or at all, our ability to commercialize our product candidates may be impaired or delayed, which
could in turn significantly harm our business.

Parties making claims against us may seek and obtain injunctive or other equitable relief, which could effectively block our ability to further
develop and commercialize our product candidates. Defense of these claims, regardless of their merit, would involve substantial litigation expense and
would be a substantial diversion of employee resources from our business 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. We
cannot predict whether any such license would be available at all or whether it would be available on commercially reasonable terms. Furthermore, even in
the absence of litigation, we may need to obtain licenses from third parties to advance our research or allow commercialization of our product candidates.
We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all. In that event, we would be unable to further develop and
commercialize our product candidates, which could harm our business significantly.

We may not be successful in obtaining or maintaining necessary rights to product components and processes for our development pipeline through
acquisitions and in-licenses.

Presently we have rights to the intellectual property, through licenses from third parties and under patent applications that we own or will own,

that we believe will facilitate the development of our product candidates. Because our programs may involve additional product candidates that may require
the use of proprietary rights held by third parties, the growth of our business will likely depend in part on our ability to acquire, in-license or use these
proprietary rights.

We may be unable to acquire or in-license any compositions, methods of use, processes or other third-party intellectual property rights from third
parties that we identify. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, which would harm our business. Even if we
are able to obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. In that event, we may
be required to expend significant time and resources to develop or license replacement technology. We may need to cease use of the compositions or
methods covered by such third-party intellectual property rights.

The licensing and acquisition of third-party intellectual property rights is a competitive area, and companies, which 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 size, cash resources and greater clinical development and commercialization capabilities.

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

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

infringement claims, which can be expensive and time-consuming. In addition, in an infringement proceeding, a court may decide that 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 proceedings could put one or more of our patents at risk of being invalidated, held
unenforceable or interpreted narrowly and could put one or more of our pending 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. 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.

69

Table of Contents

Interference proceedings provoked by third parties or brought by the USPTO may be necessary to determine the priority of inventions with respect

to our patents or patent applications or those of our licensors. An unfavorable outcome could 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 or interference 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. We may not be able to prevent, alone or with
our licensors, misappropriation of our trade secrets or confidential information, particularly in countries where the laws may not protect those rights as fully
as in the United States.

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

our confidential information could be compromised by disclosure during this type of litigation. 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.

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. While 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, but are not limited to, failure to respond to official actions within prescribed time limits, non-payment of fees
and failure to properly legalize and submit formal documents. In such an event, our competitors might be able to enter the market, which would have a
material adverse effect on our business.

The lives of our patents may not be sufficient to effectively protect our products and business.

Patents have a limited lifespan. In the United States, the natural expiration of a patent is generally 20 years after its first effective filing date.

Although various extensions may be available, the life of a patent, and the protection it affords, is limited. Even if patents covering our product candidates
are obtained, once the patent life has expired for a product, we may be open to competition from biosimilar or generic medications. In addition, although
upon issuance in the United States a patent’s life can be increased based on certain delays caused by the USPTO, this increase can be reduced or eliminated
based on certain delays caused by the patent applicant during patent prosecution. If we do not have sufficient patent life to protect our products, our
business and results of operations will be adversely affected.

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

We or our licensors 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. For example, we may have inventorship disputes arise from conflicting obligations of
consultants or others who are involved in developing our product candidates. Litigation may be necessary to defend against these and other claims
challenging inventorship. If we or our licensors 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 or our licensors are successful in defending against such claims, litigation could result in substantial costs and be a
distraction to management and other employees.

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

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, as applicable, is invalid and/or unenforceable. In patent litigation in the
United States, defendant counterclaims alleging invalidity and/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 United States or
abroad, even outside the context of litigation. Such mechanisms include IPR, ex parte re-examination and post grant review in the United States, and
equivalent proceedings in foreign jurisdictions (e.g., opposition proceedings). Such proceedings could

70

Table of Contents

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 unpatentability, invalidity and unenforceability is unpredictable. With respect to the validity question, for example, we cannot be certain that
there is no invalidating prior art, of which we, our patent counsel and the patent examiner were unaware during prosecution. If a defendant were to prevail
on a legal assertion of unpatentability, invalidity and/or unenforceability, we would lose at least part, and perhaps all, of the patent protection on our
product candidates. Such a loss of patent protection could have a material adverse impact on our business.

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

As is the case with other biopharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining

and enforcing patents in the biopharmaceutical industry involve both technological and legal complexity, and is therefore costly, time-consuming and
inherently uncertain. Recent U.S. Supreme Court rulings have narrowed the scope of patent protection available in certain circumstances and weakened the
rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination
of events has created uncertainty with respect to the value of patents, once obtained. Depending on decisions by the U.S. Congress, the federal courts, and
the USPTO, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to
enforce our existing patents and patents that we might obtain in the future. For example, in the 2013 case, Assoc. for Molecular Pathology v. Myriad
Genetics, Inc., the U.S. Supreme Court held that certain claims to DNA molecules are not patentable. While we do not believe that any of the patents
owned or licensed by us will be found invalid based on this decision, we cannot predict how future decisions by the courts, the U.S. Congress or the
USPTO may impact the value of our patents.

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

We may not be able to protect our intellectual property rights outside the United States. Filing, prosecuting and defending patents on product

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

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

We may be subject to claims that our employees, 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. We may be subject to claims that we or our employees, 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. 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.

Risks Related to Ownership of Our Common Stock

Table of Contents

The price of our stock has been and may continue to be volatile, and you could lose all or part of your investment.

The trading price of our common stock following our IPO in October 2018 has been and is likely to continue to be highly volatile and could be

subject to wide fluctuations in response to various factors, some of which are beyond our control, including limited trading volume. In addition to the
factors discussed in this “Risk Factors” section, these factors include:

the commencement, enrollment or results of our ongoing and planned clinical trials of our product candidates or any future clinical trials we
or Servier may conduct, or changes in the development status of our product candidates;

our or Servier’s decision to initiate a clinical trial, not to initiate a clinical trial or to terminate an existing clinical trial;

adverse results or delays in clinical trials;

any delay in our regulatory filings for our product candidates and any adverse development or perceived adverse development with respect
to the applicable regulatory authority’s review of such filings, including without limitation the FDA’s issuance of a “refusal to file” letter or
a request for additional information;

our failure to commercialize our product candidates;

adverse regulatory decisions, including failure to receive regulatory approval of our product candidates;

changes in laws or regulations applicable to our products, including but not limited to clinical trial requirements for approvals;

adverse developments concerning the manufacture or supply of our product candidates;

our inability to obtain adequate product supply for any approved product or inability to do so at acceptable prices;

our inability to establish collaborations if needed;

additions or departures of key scientific or management personnel;

unanticipated serious safety concerns related to immuno-oncology or related to the use of our product candidates or pre-conditioning
regimen;

introduction of new products or services offered by us or our competitors;

announcements of significant acquisitions, strategic partnerships, joint ventures or capital commitments by us or our competitors;

our ability to effectively manage our growth;

the size and growth of our initial cancer target markets;

our ability to successfully treat additional types of cancers or at different stages;

disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to obtain patent protection
for our technologies;

changes in the structure of healthcare payment systems;

significant lawsuits, including patent or stockholder litigation;

significant business disruptions caused by natural or man-made disasters, such as the COVID-19 pandemic;

general political and economic conditions; and

other events or factors, many of which are beyond our control.

In addition, the stock market in general, and the Nasdaq Global Select Market and biopharmaceutical companies 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, securities
class action litigation has often been instituted against companies following periods of volatility in the market price of a company’s securities. This type of
litigation, if instituted, could result in substantial costs and a diversion of management’s attention and resources, which would harm our business, operating
results or financial condition.

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

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

Anti-takeover provisions under our charter documents and Delaware law could delay or prevent a change of control which could limit the market price
of our common stock and may prevent or frustrate attempts by our stockholders to replace or remove our current management.

Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that could delay or prevent a change of

control of our company or changes in our board of directors that our stockholders might consider favorable. Some of these provisions include:

•

•

•

•
•

•

•

a board of directors divided into three classes serving staggered three-year terms, such that not all members of the board will be elected at
one time;

a prohibition on stockholder action through written consent, which requires that all stockholder actions be taken at a meeting of our
stockholders;

a requirement that special meetings of stockholders be called only by the chair of the board of directors, the chief executive officer, or by a
majority of the total number of authorized directors;

advance notice requirements for stockholder proposals and nominations for election to our board of directors;

a requirement that no member of our board of directors may be removed from office by our stockholders except for cause and, in addition
to any other vote required by law, upon the approval of not less than two-thirds of all outstanding shares of our voting stock then entitled to
vote in the election of directors;

a requirement of approval of not less than two-thirds of all outstanding shares of our voting stock to amend any bylaws by stockholder
action or to amend specific provisions of our certificate of incorporation; and

the authority of the board of directors to issue preferred stock on terms determined by the board of directors without stockholder approval
and which preferred stock may include rights superior to the rights of the holders of common stock.

In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporate Law,
which may prohibit certain business combinations with stockholders owning 15% or more of our outstanding voting stock. These anti-takeover provisions
and other provisions in our amended and restated certificate of incorporation and amended and restated bylaws could make it more difficult for
stockholders or potential acquirors to obtain control of our board of directors or initiate actions that are opposed by the then-current board of directors and
could also delay or impede a merger, tender offer or proxy contest involving our company. These provisions could also discourage proxy contests and make
it more difficult for you and other stockholders to elect directors of your choosing or cause us to take other corporate actions you desire. Any delay or
prevention of a change of control transaction or changes in our board of directors could cause the market price of our common stock to decline.

General Risk Factors

Unstable market and economic conditions may have serious adverse consequences on our business, financial condition and stock price.

The global credit and financial markets have experienced extreme volatility and disruptions in the past, most recently as a result of the COVID-19

pandemic. These disruptions can result in severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic
growth, increases in unemployment rates and uncertainty about economic stability. There can be no assurance that further deterioration in credit and
financial markets and confidence in economic conditions will not occur. Our general business strategy may be adversely affected by any such economic
downturn, volatile business environment or continued unpredictable and unstable market conditions. If the current equity and credit markets deteriorate, it
may make any necessary debt or equity financing more difficult, more costly and more dilutive. Our portfolio of corporate and government bonds would
also be adversely impacted. Failure to secure any necessary financing in a timely manner and on favorable terms could have a material adverse effect on
our operations, growth strategy, financial performance and stock price and could require us to delay or abandon clinical development plans. In addition,
there is a risk that one or more of our current service providers, manufacturers and other partners may not survive an economic downturn, which could
directly affect our ability to attain our operating goals on schedule and on budget.

Sales of a substantial number of shares of our common stock by our existing stockholders in the public market could cause our stock price to fall.

Sales of a substantial number of shares of our common stock in the public market or the perception that these sales might occur, including by any

of our directors, officers or larger shareholders, could depress the market price of our common stock and could impair our ability to raise capital through
the sale of additional equity securities. We are unable to predict the effect that sales may have on the prevailing market price of our common stock.

If securities or industry analysts issue an adverse or misleading opinion regarding our stock, our stock price and trading volume could decline.

The trading market for our common stock could be influenced by the research and reports that industry or securities analysts publish about us or
our business. If any of the analysts who cover us issue an adverse or misleading opinion regarding us, our business model, our intellectual property or our
stock performance, or if the clinical trials and operating results fail to meet the expectations of analysts, our stock price would likely decline. If one or more
analysts cease coverage of us or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock
price or trading volume to decline.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

Our corporate headquarters are located in South San Francisco, California, which consists of approximately 68,000 square feet for office and

laboratory space. The lease for our headquarters commenced March 1, 2019 and has an initial 10-year term expiring on June 15, 2023. We entered into an
additional lease in October 2018 for approximately 14,943 square feet of office and laboratory space in South San Francisco near our headquarters. This
lease has an initial term of ten years and four months and commenced on November 1, 2018.

In February 2019, we entered into a lease for approximately 118,000 square feet to develop a state-of-the-art cell therapy manufacturing facility

in Newark, California. The lease commenced in November 2020 and has an initial term of 15 years and eight months.

We believe that our existing facilities and other available properties will be sufficient for our needs for the foreseeable future.

Item 3. Legal Proceedings.

From time to time, we may become involved in litigation or other legal proceedings. We are not currently a party to any litigation or legal

proceedings that, in the opinion of our management, are likely to have a material adverse effect on our

74

business. Regardless of outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources
and other factors.

Item 4. Mine Safety Disclosures.

Not applicable.

Table of Contents

We have never declared or paid any cash dividends on our capital stock. We currently intend to retain all available funds and any future earnings to

support our operations and finance the growth and development of our business. We do not intend to pay cash dividends on our common stock for the
foreseeable future. Any future determination related to our dividend policy will be made at the discretion of our board of directors and will depend upon,
among other factors, our results of operations, financial condition, capital requirements, contractual restrictions, business prospects and other factors our
board of directors may deem relevant.

Use of Proceeds from Initial Public Offerings of Common Stock

In October 2018, we completed our initial public offering, and sold 18,000,000 shares of our common stock at a price of $18.00 per share pursuant

to registration statements on Form S-1 (File Nos. 333-227333 and 333-227774) that were declared or became effective on October 10, 2018. Additionally,
the underwriters exercised their option to purchase additional shares for an additional 2,700,000 shares at $18.00 per share. As a result of our IPO, we
raised a total of approximately $343.3 million in net proceeds after deducting underwriting discounts and commissions of $26.1 million and offering
expenses of $3.2 million. Upon completion of our IPO, (1) all outstanding shares of our Series A convertible preferred stock were converted into
61,655,922 shares of common stock and (2) we issued 7,856,176 shares of common stock upon the automatic conversion of the $120.2 million aggregate
principal amount of convertible promissory notes sold in September 2018.  

Upon receipt, the net proceeds from our IPO were held in cash, cash equivalents and investments. As of December 31, 2020, we have used $221.1
million of the net proceeds from our IPO. The net proceeds from our IPO are being used, together with our cash and cash equivalents, short-term and long-
term investments, to fund continued advancement of our product pipeline, with the balance to be used to fund working capital and other general corporate
purposes, which may include licensing, acquiring or investing in complementary businesses, technologies, products or assets.

Purchases of Equity Securities by the Issuer and Affiliated Purchasers

None.

Item 6. Selected Consolidated Financial Data.

We have elected to comply with Item 301 of Regulation S-K, as amended February 10, 2021, and are omitting this disclosure in reliance thereon.

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

The following discussion contains management’s discussion and analysis of our financial condition and results of operations and should be read

together with “Selected Financial Data” and the historical consolidated financial statements and the notes thereto included in “Financial Statements and
Supplementary Data”. This discussion contains forward-looking statements that reflect our plans, estimates and beliefs and involve numerous risks and
uncertainties, including but not limited to those described in the “Risk Factors” section of this Annual Report. Actual results may differ materially from
those contained in any forward-looking statements. You should carefully read “Special Note Regarding Forward-Looking Statements” and “Risk Factors.”

Overview

We are a clinical stage immuno-oncology company pioneering the development and commercialization of genetically engineered allogeneic T cell
therapies for the treatment of cancer. We are developing a pipeline of off-the-shelf T cell product candidates that are designed to target and kill cancer cells.
Our engineered T cells are allogeneic, meaning they are derived from healthy donors for intended use in any patient, rather than from an individual patient
for that patient’s use, as in the case of autologous T cells. We believe this key difference will enable us to deliver readily available treatments faster, more
reliably, at greater scale, and to more patients.

We have a deep pipeline of allogeneic chimeric antigen receptor (CAR) T cell product candidates targeting multiple promising antigens in a host

of hematological malignancies and solid tumors. Pursuant to the Exclusive Collaboration and License Agreement with Servier (Servier Agreement), we
have exclusive rights to ALLO-501 and ALLO-501A, CAR T cell product candidates targeting CD19, in the United States, while Servier retains exclusive
rights for these product candidates for all other countries. ALLO-501 and ALLO-501A use Cellectis S.A. (Cellectis) technologies under which Servier
holds an exclusive worldwide license from Cellectis.

77

Table of Contents

We are sponsoring a Phase 1 clinical trial (the ALPHA trial) of ALLO-501 in patients with R/R non-Hodgkin lymphoma (NHL). We are
continuing the ALPHA trial to further explore and optimize the lymphodepletion regimen and treatment. We are also progressing the development of the
second-generation version of ALLO-501, known as ALLO-501A. We have removed rituximab recognition domains in ALLO-501A, which we believe will
potentially facilitate treatment of more patients, as rituximab is a typical part of a treatment regimen for a patient with NHL. We initiated a Phase 1/2
clinical trial for ALLO-501A (the ALPHA2 trial) in the second quarter of 2020 and, subject to data, we plan to progress to the Phase 2 portion of the trial in
2021.

We are also progressing three programs targeting B-cell maturation antigen (BCMA) for the treatment of multiple myeloma. We initiated a Phase

1 clinical trial (the UNIVERSAL trial) of ALLO-715, an allogeneic CAR T cell product candidate targeting BCMA, in adult patients with R/R multiple
myeloma in the third quarter of 2019. In January 2020, we entered into a clinical trial collaboration agreement with SpringWorks Therapeutics, Inc.
(SpringWorks) to evaluate ALLO-715 in combination with SpringWorks’ investigational gamma secretase inhibitor, nirogacestat, in patients with R/R
multiple myeloma. In December 2020, the FDA cleared our investigational new drug application (IND) and we recently initiated this combination trial as a
cohort of the UNIVERSAL trial. Finally, we are advancing ALLO-605, an allogeneic CAR T cell product candidate targeting BCMA and our first product
candidate to incorporate our TurboCAR technology. We expect to submit an IND in the first half of 2021 to initiate a Phase 1 clinical trial of ALLO-605.

We are continuing to enroll patients in the ALPHA trial, ALPHA2 trial and UNIVERSAL trial, however, enrollment of new patients in all three

trials and the ability to conduct patient follow-up is being adversely impacted by the COVID-19 pandemic. We have also limited the number of staff
working at our facilities. The exact timing of delays and overall impact of the COVID-19 pandemic to our business, preclinical studies and clinical trials is
currently unknown, and we are monitoring the pandemic as it continues to rapidly evolve.

In December 2020, the FDA cleared our IND to initiate a Phase 1 clinical trial (the TRAVERSE trial) of ALLO-316, an allogeneic CAR T cell

product candidate targeting CD70, in adult patients with advanced or metastatic clear cell renal cell carcinoma (ccRCC). The TRAVERSE trial is expected
to initiate in the first quarter of 2021.

Since inception, we have had significant operating losses. Our net loss was $250.2 million for the year ended December 31, 2020. As of

December 31, 2020, we had an accumulated deficit of $646.3 million. As of December 31, 2020, we had $1.0 billion in cash and cash equivalents and
investments. We expect to continue to incur net losses for the foreseeable future, and we expect our research and development expenses and general and
administrative expenses will continue to increase.

Our Research and Development and License Agreements

Asset Contribution Agreement with Pfizer

In April 2018, we entered into an Asset Contribution Agreement (Pfizer Agreement) with Pfizer pursuant to which we acquired certain assets and

assumed certain liabilities from Pfizer, including agreements with Cellectis and Servier as described below, and other intellectual property for the
development and administration of CAR T cells for the treatment of cancer. See Notes 6 and 7 to our consolidated financial statements included elsewhere
in this report for further description of the Pfizer Agreement.

Research Collaboration and License Agreement with Cellectis

In June 2014, Pfizer entered into a Research Collaboration and License Agreement with Cellectis. In April 2018, Pfizer assigned the agreement to
us pursuant to the Pfizer Agreement. In March 2019, we terminated the agreement with Cellectis and entered into a new license agreement with Cellectis.
See Note 7 to our consolidated financial statements included elsewhere in this report for further descriptions of the prior agreement with Cellectis and the
new license agreement with Cellectis.

Exclusive License and Collaboration Agreement with Servier

In October 2015, Pfizer entered into an Exclusive License and Collaboration Agreement (Servier Agreement) with Servier to develop,

manufacture and commercialize certain allogeneic anti-CD19 CAR products, including UCART19, in the United States with the option to obtain the rights
over certain additional allogeneic anti-CD19 CAR product candidates and for allogeneic CAR T cell product candidates directed against one additional
target. In April 2018, Pfizer assigned the agreement to

78

Table of Contents

us pursuant to the Pfizer Agreement. In October 2019, we agreed to waive our rights to the one additional target. See Note 7 to our consolidated financial
statements included elsewhere in this report for further description of the Servier Agreement.

Collaboration and License Agreement with Notch

On November 1, 2019, we entered into a Collaboration and License Agreement (the Notch Agreement) with Notch Therapeutics Inc. (Notch),

pursuant to which Notch granted us an exclusive, worldwide, royalty-bearing, sublicensable license under certain of Notch’s intellectual property to
develop, make, use, sell, import, and otherwise commercialize therapeutic gene-edited T cell and/or natural killer cell products from induced pluripotent
stem cells directed at certain CAR targets for initial application in NHL, ALL and multiple myeloma. In addition, Notch has granted us an option to add
certain specified targets to our exclusive license in exchange for an agreed upon per-target option fee.

The Notch Agreement includes a research collaboration to conduct research and pre-clinical development activities to generate engineered cells

directed to our exclusive targets, which will be conducted in accordance with an agreed research plan and budget under the oversight of a joint
development committee. See Note 7 to our consolidated financial statements included elsewhere in this report for further description of the Notch
Agreement.

In connection with the execution of the Notch Agreement, we made an upfront payment to Notch of $10.0 million. In addition, we made a $5.0

million investment in Notch’s series seed convertible preferred stock. In February 2021, we made a further investment as part of a Series A preferred stock
financing of Notch of approximately $15.9 million. Immediately following this investment, we had a 17% ownership interest in Notch’s capital stock on a
fully diluted basis.

Strategic Alliance with The University of Texas MD Anderson Cancer Center

On October 6, 2020, we entered into a strategic five-year collaboration agreement with The University of Texas MD Anderson Cancer Center

(MD Anderson) for the preclinical and clinical investigation of allogeneic CAR T cell product candidates. See Note 7 to our consolidated financial
statements included elsewhere in this report for further description of the agreement with MD Anderson.

License Agreement with Allogene Overland Biopharm (CY) Limited

On December 14, 2020, we entered into a License Agreement with Allogene Overland Biopharm (CY) Limited (Allogene Overland), a joint

venture established by us and Overland Pharmaceuticals (CY) Inc. (Overland), pursuant to a Share Purchase Agreement, dated December 14, 2020, for the
purpose of developing, manufacturing and commercializing certain allogeneic CAR T cell therapies for patients in greater China, Taiwan, South Korea and
Singapore (the JV Territory).

Pursuant to the Share Purchase Agreement, we acquired Seed Preferred Shares in Allogene Overland representing 49% of Allogene Overland's

outstanding stock as partial consideration for the License Agreement, and Overland acquired Seed Preferred Shares representing 51% of Allogene
Overland's outstanding stock for $117.0 million in upfront and certain quarterly cash payments, to support operations of Allogene Overland. As of
December 31, 2020, Allogene and Overland are the sole equity holders in Allogene Overland. The Company received $40 million from Allogene Overland
as partial consideration for the License Agreement .

Pursuant to the License Agreement, we granted Allogene Overland an exclusive license to develop, manufacture and commercialize certain
allogeneic CAR T cell candidates directed at four targets, BCMA, CD70, FLT3, and DLL3, in the JV Territory. As consideration, we would also be entitled
to additional regulatory milestone payments of up to $40.0 million and, subject to certain conditions, tiered low-to-mid single-digit sales royalties.

Promises that we concluded were distinct performance obligations in the License Agreement included: (1) the license of intellectual property and
delivery of know-how, (2) the manufacturing license, related know-how and support, (3) if and when available know-how developed in future periods, and
(4) participation in the joint steering committee.

In order to determine the transaction price, we evaluated all the payments to be received during the duration of the contract. Fixed consideration

exists in the form of the upfront payment. Regulatory milestones and royalties were considered variable consideration. We constrain the estimated variable
consideration when we assess it is probable that a significant reversal in the amount of cumulative revenue recognized may occur in future periods.
Milestone fees were constrained and not included in the transaction price due to the uncertainties of research and development. We re-evaluate the
transaction price, including the estimated variable consideration included in the transaction price and all constrained amounts, in each reporting

79

Table of Contents

period and as uncertain events are resolved or other changes in circumstances occur. The shares of Series Seed Preferred Stock were accounted for as part
of our joint venture and equity method accounting upon formation of the joint venture, and as such, were excluded from the transaction price. We
determined that the initial transaction price consists of the upfront payment of $40.0 million. The allocation of the transaction price is performed based on
standalone selling prices, which are based on estimated amounts that we would charge for a performance obligation if it were sold separately. The
transaction price allocated to the license of intellectual property and delivery of know-how will be recognized upon grant of license and delivery of know-
how. The transaction price allocated to (i) the manufacturing license, related know-how and support services, (ii) if and when available know-how
developed in future periods, and (iii) participation in the joint steering committee, will be recognized over time as the services are delivered. Funds received
in advance are recorded as deferred revenue and will be recognized as the performance obligations are satisfied. We expect a substantial portion of the
upfront payment of $40 million will be recognized during the quarter ending on March 31, 2021. See Note 7 to our consolidated financial statements
included elsewhere in this report for further description of the License Agreement and Share Purchase Agreement with Allogene Overland.

Transition Services Agreement

In connection with the closing of the Pfizer Agreement, we entered into a Transition Services Agreement (TSA) with Pfizer in April 2018,

pursuant to which we obtained from Pfizer certain (i) research and development services, including services relating to testing, studies, and clinical trials,
project management services, laboratory equipment and operations services, animal care services, data storage services and regulatory strategy services,
and (ii) general and administrative services, including business technology services, compliance services, finance/accounting services, and procurement,
manufacturing and supply chain services, with respect to the assets that we purchased from Pfizer. Under the TSA, Pfizer also provided us with certain
facilities and facility management services. The services were provided by certain employees of Pfizer as independent contractors of Allogene. We believe
that it was helpful for Pfizer to provide such services to us under the TSA to help facilitate the efficient operation of our business after the asset purchase.
Pfizer began providing the services in May 2018 and the TSA was terminated in September 2019.

Components of Results of Operations

Operating Expenses

Research and Development

To date, our research and development expenses have related primarily to discovery efforts, preclinical and clinical development, and
manufacturing of our product candidates. Research and development expenses for the year ended December 31, 2020 included costs associated with our
clinical and preclinical stage pipeline candidates and research into newer technologies. The most significant research and development expenses for the
year relate to costs incurred for the development of our most advanced product candidates and include:

•

•

•

•

•

•

expenses incurred under agreements with our collaboration partners and third-party contract organizations, investigative clinical trial sites
that conduct research and development activities on our behalf, and consultants;

costs related to the production of clinical materials, including fees paid for raw materials and to contract manufacturers;

laboratory and vendor expenses related to the execution of preclinical and clinical trials;

employee-related expenses, which include salaries, benefits and stock-based compensation;

facilities and other expenses, which include expenses for rent and maintenance of facilities, depreciation and amortization expense and
other supplies; and

other significant research and development costs, which include overhead costs.

We expense all research and development costs in the periods in which they are incurred. We accrue for costs incurred as the services are being

provided by monitoring the status of the project and the invoices received from our external service providers. We adjust our accrual as actual costs become
known. Where contingent milestone payments are due to third parties under research and development arrangements or license agreements, milestone
payment obligations are expensed when the milestone results are achieved.

We are required to reimburse Servier for 60% of the costs associated with the prior development of UCART19, including for the CALM and

PALL clinical trials of UCART19. We accrue for costs incurred by monitoring the status of

80

Table of Contents

clinical trials and the invoices received from Servier. We adjust our accrual as actual costs become known. Servier is required to reimburse us for 40% of
the costs associated with the development of ALLO-501 and ALLO-501A. Collaboration expenses and cost reimbursement are recorded on a net basis as a
research and development expense in our consolidated statements of operations and comprehensive loss.

Research and development activities are central to our business model. Product candidates in later stages of clinical development generally have
higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials.
We expect our research and development expenses to increase in the future as our clinical programs progress and as we seek to initiate clinical trials of
additional product candidates. The cost of advancing our manufacturing process as well as the cost of manufacturing product candidates for clinical trials
are included in our research and development expense. We also expect to incur increased research and development expenses as we selectively identify and
develop additional product candidates. However, it is difficult to determine with certainty the duration and completion costs of our current or future
preclinical programs and clinical trials of our product candidates.

The duration, costs and timing of clinical trials and development of our product candidates will depend on a variety of factors that include, but are

not limited to, the following:

•

•

•

•

•

•

•

•

•

•

•

•

per patient trial costs;

biomarker analysis costs;

the cost and timing of manufacturing for the trials;

the number of patients that participate in the trials;

the number of sites included in the trials;

the countries in which the trials are conducted;

the length of time required to enroll eligible patients;

the total number of cells that patients receive;

the drop-out or discontinuation rates of patients;

potential additional safety monitoring or other studies requested by regulatory agencies;

the duration of patient follow-up; and

the efficacy and safety profile of the product candidates.

In addition, the probability of success for each product candidate will depend on numerous factors, including safety, efficacy, competition,

manufacturing capability and commercial viability. We will determine which programs to pursue and how much to fund each program in response to the
scientific and clinical success of each product candidate, as well as an assessment of each product candidate’s commercial potential.

Because our product candidates are still in clinical and 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 product candidates or whether, or when, we may achieve
profitability.

General and Administrative

General and administrative expenses consist primarily of salaries and other staff-related costs, including stock-based compensation for options and

restricted stock units granted. General and administrative expenses also include stock-based compensation expense related to the modification of shares of
common stock issued to our founders to include vesting conditions. Other significant costs include costs relating to facilities and overhead costs, legal fees
relating to corporate and patent matters, insurance, investor relations costs, fees for accounting and consulting services, information technology, and other
general and administrative costs. General and administrative costs are expensed as incurred, and we accrue for services provided by third parties related to
the above expenses by monitoring the status of services provided and receiving estimates from our service providers, and adjusting our accruals as actual
costs become known.

We expect our general and administrative expenses to increase over the next several years to support our continued research and development

activities, manufacturing activities, potential commercialization of our product candidates and the increased costs of operating as a public company,
including additional compliance-related expenses as a result of no longer being an emerging growth company. These increases are anticipated to include
increased costs related to the hiring of additional

81

Table of Contents

personnel, developing infrastructure, fees to outside consultants, lawyers and accountants, and increased costs associated with being a public company such
as expenses related to services associated with maintaining compliance with Nasdaq listing rules and SEC requirements, insurance and investor relations
costs.

Other (Expense) Income, Net:

Change in Fair Value of 2018 Notes

In September 2018, we sold and issued an aggregate of $120.2 million in convertible promissory notes (2018 Notes) and received net cash
proceeds of $116.8 million. We elected on issuance to account for the 2018 Notes at fair value until their settlement. In the year ended December 31, 2018,
the change in fair value of the 2018 Notes was recognized through the statement of operations. The 2018 Notes settled on the closing of our IPO in October
2018.

Interest Expense

Interest expense consists of debt issuance costs we incurred to issue the 2018 Notes. The debt issuance costs were expensed on issuance because

we elected to record the 2018 Notes at fair value.

Interest and Other Income, Net

Interest and other income, net consists of interest earned on our cash, cash equivalents and investments and gains and losses recognized during the

period.

Other Expense

Other expense consists of non-operating expenses, including our share of equity investments' net losses for the period.

Research and development expenses were $193.0 million and $144.5 million for the years ended December 31, 2020 and 2019, respectively. The

net increase of $48.5 million was primarily due to an increase in personnel related costs of $28.9

82

Table of Contents

million, of which $11.9 million was increased stock-based compensation expense, an increase in external costs relating to the advancement of our product
candidates of $16.1 million, and an increase in allocated building rent and facilities costs of $5.3 million, offset by a decrease in TSA expenses of $1.2
million and a decrease in travel related costs of $1.0 million due to the impact of the COVID-19 pandemic.

Research and development expenses were $144.5 million and $151.9 million for the years ended December 31, 2019 and 2018, respectively. The

net decrease of $7.3 million was primarily due to $109.4 million in expenses related to the acquired in-process research and development assets with no
alternative future use, acquired from Pfizer in April 2018. This was offset by a $102.1 million increase, driven primarily by increased external costs related
to the advancement of our pipeline candidates of $44.6 million, increased personnel related costs of $40.8 million, including an increase of $18.0 million in
stock-based compensation expense, and increased allocated building rent and facilities costs of $19.2 million, offset by a decrease of $4.0 million in Pfizer
TSA costs.

General and Administrative Expenses

General and administrative expenses were $65.3 million and $57.5 million for the years ended December 31, 2020 and 2019, respectively. The net

increase of $7.8 million was primarily due to an increase in personnel related costs of $8.4 million, of which $7.3 million was increased stock-based
compensation expense, an increase in building rent and facilities costs of $2.4 million, an increase in legal and professional services of $1.2 million, offset
by a decrease in TSA expenses of $3.5 million and a decrease in travel related costs of $0.8 million due to the impact of the COVID-19 pandemic.

General and administrative expenses were $57.5 million and $41.0 million for the years ended December 31, 2019 and 2018, respectively. The net

increase of $16.5 million was primarily due to a $18.6 million increase in personnel related costs, including an increase of $9.7 million in stock-based
compensation expense, and increased legal and professional services of $2.7 million. This was offset by a $5.1 million decrease due to a greater proportion
of facilities costs being allocated to research and development expenses and a $1.5 million decrease in expenses incurred under the Pfizer TSA.

Change in Fair Value of 2018 Notes

The change in fair value of convertible notes of $21.2 million for the year ended December 31, 2018 was due to the accretion of the 2018 Notes to

their fair value from the date of issuance at $120.2 million to the fair value upon settlement of $141.4 million which occurred in 2018. There were no
similar transactions in the years ended December 31, 2020 and 2019.

Interest Expense

Interest expense of $3.4 million for the year ended December 31, 2018 consists of debt issuance costs that were expensed on issuance of the 2018

Notes. There were no similar transactions in the years ended December 31, 2020 and 2019.

Interest and Other Income, Net

Interest and other income, net was $9.2 million and $17.4 million for the years ended December 31, 2020 and 2019, respectively. The $8.2 million

decrease was due to lower yields and a corresponding reduction in the interest earned on our cash, cash equivalents and investments.

Interest and other income, net was $17.4 million and $5.8 million for the years ended December 31, 2019 and 2018, respectively. The $11.6
million increase was due to interest earned on our cash equivalents and investments as our combined cash, cash equivalents and investments interest
earning balance was higher on average during the 12 months ended December 31, 2019 compared to the 12 months ended December 31, 2018.

Liquidity, Capital Resources and Plan of Operations

To date, we have incurred significant net losses and negative cash flows from operations. As of December 31, 2020, we had $1.0 billion in cash,
cash equivalents and investments. We believe that the aggregate of our current cash and cash equivalents and investments available for operations will be
sufficient to fund our operations for at least the next 12 months from the date this Annual Report on Form 10-K is filed with the SEC.

Our operations have been financed primarily by net proceeds from the sale and issuance of our convertible preferred stock, the issuance of the

2018 Notes, net proceeds from our IPO, our at-the-market (ATM) offerings, and our June 2020 underwritten public offering. In connection with our IPO in
2018, we sold an aggregate of 20,700,000 shares of our common

83

Table of Contents

stock (inclusive of 2,700,000 shares of common stock pursuant to the over-allotment option granted to the underwriters) at a price of $18.00 per share and
received approximately $343.3 million in net proceeds. In November 2019, we entered into a sales agreement with Cowen and Company, LLC (Cowen)
under which we may from time to time issue and sell shares of our common stock through Cowen in ATM offerings for an aggregate offering price of up to
$250.0 million. During the year ended December 31, 2020, we sold an aggregate of 848,663 shares of common stock in ATM offerings resulting in net
proceeds of $26.2 million. As of December 31, 2020, $167.3 million remains available for sale under the sales agreement with Cowen.

In June 2020, we sold 13,457,447 shares of our common stock, which included 1,755,319 shares sold pursuant to the full exercise of the

underwriters' option to purchase additional shares, in an underwritten public offering at a price of $47.00 per share, which resulted in net proceeds of
approximately $595.7 million after deducting the underwriting discounts and commissions and other expenses.

Capital Resources

Our primary use of cash is to fund construction projects for our manufacturing facility and operating expenses, which consist primarily of clinical
manufacturing and research and development expenditures related to our lead product candidates, other research efforts, and to a lesser extent, general and
administrative expenditures. Cash used to fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the change in
our outstanding accounts payable and accrued expenses and other current liabilities.

Our product candidates are still in the early stages of clinical and preclinical development and the outcome of these efforts is

uncertain. Accordingly, we cannot estimate the actual amounts necessary to successfully complete the development and commercialization of our product
candidates or whether, or when, we may achieve profitability. Until such time, if ever, as we can generate substantial product revenue, we expect to finance
our cash needs through a combination of equity or debt financings and collaboration and license arrangements. If, and when, we do raise additional capital
through public or private equity offerings, the ownership interest of our existing stockholders will be diluted, and the terms of these securities may include
liquidation or other preferences that adversely affect our stockholders’ rights. If we raise additional capital through debt financing, we may be subject to
covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If
we are unable to raise capital when needed, we will need to delay, reduce or terminate planned activities to reduce costs. Doing so will likely harm our
ability to execute our business plans.

During the year ended December 31, 2020, cash used in operating activities of $115.1 million was attributable to a net loss of $250.2 million,

substantially offset by non-cash charges of $81.2 million and a net change of $53.9 million in our net operating assets and liabilities. The non-cash charges
consisted primarily of stock-based compensation of $65.3 million, depreciation and amortization of $7.4 million, non-cash rent expense of $4.0 million and
net amortization and accretion on investment securities of $3.3 million. The net change in operating assets and liabilities was primarily due to a $39.0
million increase in deferred revenue within current liabilities, a $18.7 million increase in accrued and other current liabilities and $0.6 million increase in
accounts payable, offset by an increase in prepaid expenses and other current assets of $3.2 million and a decrease in other-long term liabilities of $1.3
million.

During the year ended December 31, 2019, cash used in operating activities of $137.4 million was attributable to a net loss of $184.6 million,

substantially offset by non-cash charges of $54.1 million and a net change of $6.9 million in our net operating assets and liabilities. The non-cash charges
consisted primarily of stock-based compensation of $46.1 million, non-

84

Table of Contents

cash rent expense of $6.8 million and depreciation and amortization of $4.4 million, offset by net amortization and accretion on investment securities of
$3.6 million. The net change in operating assets and liabilities was primarily due to a $6.4 million increase in accrued and other current liabilities, offset by
an increase in prepaid expenses and other current assets of $5.4 million, an increase in other long-term assets of $4.4 million and a decrease in other-long
term liabilities of $2.4 million.

During the year ended December 31, 2018, cash used in operating activities of $44.7 million was attributable to a net loss of $211.5 million,
substantially offset by non-cash charges of $154.8 million and a net change of $12.1 million in our net operating assets and liabilities. The non-cash charges
consisted primarily of acquired in-process research and development expense resulting from the asset acquisition from Pfizer of $109.4 million, change in
fair value of convertible notes payable of $21.2 million and $18.6 million of stock-based compensation. The net change in operating assets and liabilities
was primarily due to a $12.1 million increase in accruals and other liabilities driven by increased professional fees and an $8.8 million increase in accounts
payable resulting from the timing of payments made to our collaboration partners and Pfizer accrued services. This was partially offset by a $8.6 million
increase in prepaid expenses and other current assets and a $0.2 million increase in other long-term assets.

Investing Activities

During the year ended December 31, 2020, net cash used by investing activities of $505.1 million was related to the purchase of investments of
$1.0 billion and purchases of property and equipment of $66.0 million, offset by cash inflows from maturities of investments of $593.6 million and cash
inflows from sales of investments of $4.8 million.

During the year ended December 31, 2019, net cash provided by investing activities of $164.1 million was related to proceeds from investment
maturities of $472.6 million, offset by cash used for investment purchases of $252.6 million, cash used in purchases of property and equipment of $50.8
million and cash used in connection with our investment in Notch’s series seed convertible preferred stock of $5.1 million, inclusive of transaction costs.

During the year ended December 31, 2018, cash used by investing activities of $632.8 million was related to the purchase of investments of
$649.3 million, cash transaction costs of $2.1 million incurred in the asset acquisition from Pfizer and the purchase of property and equipment of $3.2
million. This was offset by cash inflows from maturities of investments of $19.2 million and cash inflows from sales of investments of $2.6 million.

Financing Activities

During the year ended December 31, 2020, net cash provided by financing activities of $633.6 million was related to net proceeds from the

issuance of common stock in ATM offerings and an underwritten public offering of $621.9 million, proceeds from the issuance of common stock upon the
exercise of stock options of $8.8 million and proceeds from the employee stock purchase plan of $2.8 million.

During the year ended December 31, 2019, net cash provided by financing activities of $59.0 million was related to net proceeds from the issuance

of common stock in ATM offerings of $54.2 million, proceeds from the issuance of common stock upon the exercise of stock options of $3.0 million and
proceeds from the employee stock purchase plan of $1.8 million.

During the year ended December 31, 2018, cash provided by financing activities of $771.2 million was related to net proceeds of $299.3 million
from the issuance of our Series A and A-1 convertible preferred stock, $116.8 million from the issuance of the 2018 Notes, $343.7 million in net proceeds
from our IPO and $11.4 million from the issuance of common stock in connection with stock option exercises.

¹ In August 2018, we entered into an operating lease agreement for our headquarters in South San Francisco. The lease term is 127 months beginning
August 2018 through February 2029. In October 2018, we entered into an operating lease agreement for additional office and laboratory space in
South San Francisco near our headquarters. The lease has a term of ten years and four months commencing on November 1, 2018. In December 2018,
we entered into an operating lease agreement for office space in New York, and another operating lease agreement for office space in Los Angeles.
The lease terms are 79 months and 36 months, respectively, with the leases commencing on December 1, 2018 and December 19, 2018, respectively.
In February 2019, we entered into a lease agreement for manufacturing space in Newark, California. The lease term is for 188 months beginning
November 2020.

Commitments

Our commitments primarily consist of obligations under our agreements with Pfizer, Cellectis, Servier and Notch. Under these agreements we are

required to make milestone payments upon successful completion of certain regulatory and sales milestones on a target-by-target and country-by-country
basis. The payment obligations under the license agreements are contingent upon future events such as our achievement of specified development,
regulatory and commercial milestones and we will be required to make development milestone payments and royalty payments in connection with the sale
of products developed under these agreements. As of December 31, 2020, we were unable to estimate the timing or likelihood of achieving the milestones
or making future product sales.

Additionally, we have entered into agreements with third-party contract manufacturers for the manufacture and processing of certain of our

product candidates for clinical testing purposes, and we have entered and will enter into other contracts in the normal course of business with contract
research organizations for clinical trials and other vendors for other services and products for operating purposes. These agreements generally provide for
termination or cancellation, other than for costs already incurred. As of December 31, 2020, the Company had non-cancellable purchase commitments of
$5.4 million.

On October 6, 2020, we announced we entered into a strategic five-year collaboration agreement with MD Anderson for the preclinical and

clinical investigation of allogeneic CAR T cell product candidates. We and MD Anderson are collaborating on the design and conduct of preclinical and
clinical studies with oversight from a joint steering committee. Under the terms of the agreement, we have committed up to $15.0 million of funding for the
duration of the agreement. Payment of this funding is contingent on mutual agreement to study orders in order for any study to be included under the
alliance. We made an upfront payment of $3.0 million to MD Anderson in the year ended December 31, 2020. We are obligated to make further payments
to MD Anderson each year upon the anniversary of the agreement effective date through the duration of the agreement term. The agreement may be
terminated by either party for material breach by the other party. Individual studies may be terminated for, among other things, material breach, health and
safety concerns or where the institutional review board, the review board at the clinical site with oversight of the clinical study, requests termination of any
study. Where any legal or regulatory authorization is finally withdrawn or terminated, the relevant study will also terminate automatically.

In July 2020, we entered into a Solar Power Purchase and Energy Services Agreement for the installation and operation of a solar photovoltaic

generating system and battery energy storage system at our manufacturing facility in Newark, California. The agreement has a term of 20 years and is
expected to commence in the first half of 2021. We are obligated to pay for electricity generated from the system at an agreed rate for the duration of the
agreement term. Termination of the agreement by us will result in a termination payment due of approximately $4.3 million. In connection with the
agreement, we maintain a letter of credit for the benefit of the service provider in the amount of $4.3 million which is disclosed as restricted cash in the
consolidated balance sheet as of December 31, 2020.

We also have a Change in Control and Severance Plan that require the funding of specific payments, if certain events occur, such as a change of

control and the termination of employment without cause.

Off-Balance Sheet Arrangements

During the periods presented, we did not have, nor do we currently have, any off-balance sheet arrangements as defined under SEC rules.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements,

which have been prepared in accordance with United States generally accepted accounting principles. The preparation of these consolidated financial
statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets
and liabilities at the date of the consolidated

86

Table of Contents

financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and on
various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying
value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or
conditions.

We believe that the assumptions and estimates associated with accrued research and development expenditures, revenue recognition, research and

development expenses, stock-based compensation and leases have the most significant impact on our consolidated financial statements. Therefore, we
consider these to be our critical accounting policies and estimates.

Accrued Research and Development Costs 

We accrue liabilities for estimated costs of research and development activities conducted by our collaboration partners and third-party service

providers, which include the conduct of preclinical and clinical studies, and contract manufacturing activities. We recorded the estimated costs of research
and development activities based upon the estimated amount of services provided but not yet invoiced, and includes these costs in the accrued and other
current liabilities on the consolidated balance sheets and within research and development expense on the consolidated statements of operations and
comprehensive loss.

We accrue for these costs based on factors such as estimates of the work completed and budget provided and in accordance with agreements
established with our collaboration partners and third-party service providers. We make significant judgments and estimates in determining the accrued
liabilities balance in each reporting period. As actual costs become known, we adjust its accrued liabilities. We have not experienced any material
differences between accrued costs and actual costs incurred since our inception.

Revenue Recognition

In the near future, our revenue is anticipated to be generated through collaboration research and license agreements. The terms of these

agreements are expected to contain multiple deliverables which may include (i) grant of licenses, (ii) transfer of know-how, (iii) research and development
activities, (iii) clinical manufacturing and, (iv) product supply. The payment terms of these agreements may include nonrefundable upfront fees, payments
for research and development activities, payments based upon the achievement of certain milestones, royalty payments based on product sales derived from
the collaboration, and payments for supplying product.

We will analyze our collaboration arrangements to assess whether they are within the scope of ASC 808, Collaborative Arrangements (ASC
808) to determine whether such arrangements involve joint operating activities performed by parties that are both active participants in the activities and
exposed to significant risks and rewards dependent on the commercial success of such activities. This assessment is performed throughout the life of the
arrangement based on changes in the responsibilities of all parties in the arrangement. For collaboration arrangements within the scope of ASC 808 that
contain multiple elements, we first determine which elements of the collaboration are deemed to be within the scope of ASC 808 and those that are more
reflective of a vendor-customer relationship and, therefore, within the scope of Topic 606, Revenue from Contracts with Customers (ASC 606). For
elements of collaboration arrangements that are accounted for pursuant to ASC 808, an appropriate recognition method is determined and applied
consistently, generally by analogy to Topic 606.

For elements of those arrangements that we determine should be accounted for under ASC 606, we assess which activities in our collaboration
agreements are performance obligations that should be accounted for separately and determine the transaction price of the arrangement, which includes the
assessment of the probability of achievement of future milestones and other potential consideration. A performance obligation represents a promise in a
contract to transfer a distinct good or service to a customer, which represents a unit of accounting in accordance with ASC 606. A performance obligation is
considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are
readily  available  to  the  customer  and  is  separately  identified  in  the  contract.  We  consider  a  performance  obligation  satisfied  once  we  have  transferred
control of a good or service to the customer, meaning the customer has the ability to use and obtain the benefit of the good or service. A portion of the
consideration should be allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied.
The total consideration which we expect to collect in exchange for our products is an estimate and may be fixed or variable. We constrain the estimated
variable consideration when we assess it is probable that a significant reversal in the amount of cumulative revenue recognized may occur in future periods.
The transaction price is re-evaluated, including the estimated variable consideration included in the transaction price and all constrained amounts, in each
reporting period and as uncertain events are resolved or other changes in circumstances occur. The allocation of the transaction price is performed based on
standalone selling prices, which are based

87

Table of Contents

on  estimated  amounts  that  we  would  charge  for  a  performance  obligation  if  it  were  sold  separately.  Revenue  is  recognized  when,  or  as,  performance
obligations in the contracts are satisfied, in the amount reflecting the expected consideration to be received from the goods or services transferred to the
customers. Funds received in advance are recorded as deferred revenue and are recognized as the related performance obligation is satisfied.

Research and Development Expenses

We expense research and development costs as incurred. Acquired intangible assets are expensed as research and development costs if, at the time

of payment, the technology is under development; is not approved by the FDA or other regulatory agencies for marketing; has not reached technical
feasibility; or otherwise has no foreseeable alternative future use.

Research and development expenses also include costs incurred for internal and sponsored and collaborative research and development activities.
Research and development costs consist of salaries and benefits, including associated stock-based compensation, and laboratory supplies and facility costs,
as well as fees paid to other entities that conduct certain research and development activities on our behalf. Costs associated with co-development activities
performed under the various license and collaboration agreements, including milestones achieved, are included in research and development expenses.

Stock-Based Compensation

We recognize compensation costs related to stock-based awards granted to employees and directors, including stock options, based on the
estimated fair value of the awards on the date of grant. We estimate the grant date fair value, and the resulting stock-based compensation, using the Black-
Scholes option-pricing model. The grant date fair value of the stock-based awards is generally recognized on a straight-line basis over the requisite service
period, which is generally the vesting period of the respective awards.

The Black-Scholes option-pricing model requires the use of subjective assumptions to determine the fair value of stock-based awards. These

assumptions include:

‑          Fair value of common stock—For grants before October 2018 when we were private and there was no public market for our common

stock, the fair value of our common stock underlying share-based awards was estimated on each grant date by our board of directors. In
order to determine the fair value of our common stock underlying option grants, our board of directors considered, among other things,
valuations of our common stock prepared by an unrelated third-party valuation firm in accordance with the guidance provided by the
American Institute of Certified Public Accountants Practice Guide, Valuation of Privately-Held-Company Equity Securities Issued as
Compensation. For all grants subsequent to our IPO in October 2018, the fair value of common stock was determined by taking the
closing price per share of common stock per Nasdaq.

‑          Expected term— The expected term represents the period that stock-based awards are expected to be outstanding. The expected term for
option grants is determined 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 stock-based awards.

‑          Expected volatility— We use an average historical stock price volatility of comparable public companies within the biotechnology and

pharmaceutical industry that were deemed to be representative of future stock price trends, in addition to some consideration to our own
stock price volatility. We continue to utilize comparable public companies as part of this process as we do not have sufficient trading
history for our common stock. We will continue to apply this process until a sufficient amount of historical information regarding the
volatility of our own stock price becomes available.

‑          Risk-free interest rate—The risk-free interest rate is based on the U.S. Treasury zero coupon issues in effect at the time of grant for periods

corresponding with the expected term of option.

‑          Expected dividend—We have never paid dividends on its common stock and have no plans to pay dividends on our common stock.

Therefore, we used an expected dividend yield of zero.

For the years ended December 31, 2020, 2019 and 2018, stock-based compensation was $65.3 million, $46.1 million and $18.6 million,
respectively. As of December 31, 2020 and 2019, we had $149.4 million and $148.6 million, respectively, of total unrecognized stock-based compensation
relating to options, restricted stock units and founders stock.

Leases

88

Table of Contents

We early adopted Accounting Standards Update (ASU) No. 2016-02, Leases as of January 1, 2018. For our long-term operating leases, we
recognized right-of-use assets and lease liabilities on our consolidated balance sheet. The lease liabilities are determined as the present value of future lease
payments using an estimated rate of interest that we would have to pay to borrow equivalent funds on a collateralized basis at the lease commencement
date. The right-of-use assets are based on the liability adjusted for any prepaid or deferred rent. For each lease, the lease term at the commencement date is
determined by considering whether renewal options and termination options are reasonably assured of exercise.

Rent expense for the operating lease is recognized on a straight-line basis over the lease term and is included in operating expenses on the

consolidated statements of operations and comprehensive loss. Variable lease payments include lease operating expenses.

We elected to exclude from our consolidated balance sheets recognition of leases having a term of 12 months or less (short-term leases) and

elected to not separate lease components and non-lease components for our long-term real estate leases.

Recent Accounting Pronouncements

Please refer to Note 2 to our consolidated financial statements for a discussion of new accounting standards and updates that may impact us.

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

Interest Rate Risk

Our cash, cash equivalents and investments of $1.0 billion as of December 31, 2020, consist of bank deposits, money market funds and available-

for-sale securities. Such interest-earning instruments carry a degree of interest rate risk; however, historical fluctuations in interest income have not been
significant for us. A 10% change in the interest rates in effect on December 31, 2020 would not have had a material effect on the fair market value of our
cash equivalents and available-for-sale securities.

Foreign Currency Exchange Rate Risk

Our collaboration agreement with Servier requires collaboration payments for shared clinical development costs to be paid in euros, and thus we

face foreign exchange risk as a result of entering into transactions denominated in currencies other than U.S. dollars. Due to the uncertain timing of
expected payments in foreign currencies, we do not utilize any forward exchange contracts. All foreign transactions settle on the applicable spot exchange
basis at the time such payments are made. An adverse movement in foreign exchange rates could have an effect on payments due and made to our
collaboration partner as well as other foreign suppliers and for license agreements. A 10% change in the applicable foreign exchange rates during the
periods presented would not have had a material effect on our consolidated financial statements. As of December 31, 2020, we had $2.5 million of other
receivables and $0.2 million of current liabilities denominated in foreign currency.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Allogene Therapeutics, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Allogene Therapeutics, Inc. (the Company) as of December 31, 2020 and 2019, the
related consolidated statements of operations and comprehensive loss, statements of convertible preferred stock and stockholders’ equity (deficit) and cash
flows for each of the three years in the period ended December 31, 2020 and the related notes (collectively referred to as the “consolidated financial
statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at
December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in
conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's
internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control-Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 25, 2021 expressed an unqualified
opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial
statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the
Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the
PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing
procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to
those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits
also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the
financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The 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 the critical audit matter does not alter in any way our opinion
on the consolidated 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.

Description of the
Matter

Accrued Research and Development Costs
As discussed in Note 1 liabilities are recorded for estimated unpaid costs of research and development activities conducted by
the Company and its collaboration partners and third-party service providers, which include the conduct of preclinical and
clinical studies, and contract manufacturing activities. Total research and development expenses were $193 million during the
year ended December 31, 2020 and include the estimated costs of accrued research and development activities for services
provided but not yet invoiced. The accrual for these costs is determined after consideration of several factors, including budgets
and estimates of the work completed in accordance with agreements established with the Company’s collaboration partners and
third-party service providers. Auditing accrued research and development costs was complex due to significant judgments and
estimates made by management in determining the required accruals.

91

Table of Contents

How We Addressed
the Matter in Our
Audit

We obtained an understanding, evaluated the design, and tested the operating effectiveness of relevant controls over the
Company’s determination of accrued research and development costs, including controls over the determination of significant
assumptions and the completeness and accuracy of the data used in determining accrued costs.

Our audit procedures included, among others, examining, on a test basis, evidence regarding the estimated accrued amounts
through comparison of expenses incurred to budgeted amounts and to expenses incurred in prior periods and obtaining an
understanding of the reasons for changes. We verified that accrued amounts were in accordance with key terms and conditions
through review of the underlying agreements with the Company’s collaboration partners and third-party service providers. We
verified expenses incurred by obtaining confirmation from the Company’s collaboration partners and further validated accrued
amounts based on information provided by third-party service providers.

ALLOGENE THERAPEUTICS, INC.
Notes to Consolidated Financial Statements

Note 1. Description of Business and Summary of Significant Accounting Policies

Allogene Therapeutics, Inc. (the Company or Allogene) was incorporated on November 30, 2017 in the State of Delaware and is headquartered in
South San Francisco, California. Allogene is a clinical-stage immuno-oncology company pioneering the development and commercialization of genetically
engineered allogeneic T cell therapies for the treatment of cancer. The Company is developing a pipeline of off-the-shelf T cell product candidates that are
designed to target and kill cancer cells.

For the period from November 30, 2017 (inception) to December 31, 2017, the Company incurred $2,000 in start-up costs to establish the

Company. Principal operations commenced in April 2018 when Allogene acquired certain assets from Pfizer Inc. (Pfizer) (see Note 6) and completed a
Series A and A-1 preferred stock financing (see Note 11).

Public Offerings

In October 2018, the Company completed an initial public offering (IPO) of its common stock. In connection with its IPO, the Company issued

and sold 20,700,000 shares of its common stock, which included 2,700,000 shares of its common stock issued pursuant to the over-allotment option granted
to the underwriters, at a price to the public of $18.00 per share. As a result of the IPO, the Company received $343.3 million in net proceeds, after
deducting underwriting discounts and commissions of $26.1 million and offering expenses of $3.2 million payable by the Company. At the closing of the
IPO, 11,743,987 shares of outstanding convertible preferred stock were automatically converted into 61,655,922 shares of common stock and the 2018
Notes (see Note 11) were automatically converted into 7,856,176 shares of common stock. Following the IPO, there were no shares of convertible preferred
stock or preferred stock outstanding.

In November 2019, the Company entered into a sales agreement with Cowen and Company, LLC (Cowen), under which the Company may from

time to time issue and sell shares of its common stock through Cowen in at-the-market (ATM) offerings for an aggregate offering price of up to
$250.0 million. The aggregate compensation payable to Cowen as the Company's sales agent equals up to 3.0% of the gross sales price of the shares sold
through it pursuant to the sales agreement. During the year ended December 31, 2020, we sold an aggregate of 848,663 shares of common stock in ATM
offerings resulting in net proceeds of $26.2 million.

In June 2020, the Company sold 13,457,447 shares of its common stock, which included 1,755,319 shares sold pursuant to the full exercise of the

underwriters' option to purchase additional shares, in an underwritten public offering at a price of $47.00 per share, which resulted in gross proceeds of
approximately $632.5 million. Net proceeds to the Company after deducting the underwriting discounts and commissions and other expenses were
approximately $595.7 million.

Forward Stock Split

On October 1, 2018, the Company filed an amendment to the Company’s amended and restated certificate of incorporation to effect a forward split
of shares of the Company’s common stock on a 1-for-5.25 basis (the Forward Stock Split). In connection with the Forward Stock Split, the conversion ratio
for the Company’s outstanding convertible preferred stock was proportionately adjusted such that the common stock issuable upon conversion of such
preferred stock was increased in proportion to the Forward Stock Split. The par value of the common stock was not adjusted as a result of the Forward
Stock Split. All references to common stock, options to purchase common stock, early exercised options, share data, per share data, convertible preferred
stock (to the extent presented on an as-converted to common stock basis) and related information contained in these financial statements have been
retrospectively adjusted to reflect the effect of the Forward Stock Split for all periods presented.

Need for Additional Capital

The Company has sustained operating losses and expects to continue to generate operating losses for the foreseeable future. The Company’s

ultimate success depends on the outcome of its research and development activities as well as the ability to commercialize the Company’s product
candidates. The Company had cash, cash equivalents and investments of $1.0 billion as of December 31, 2020. Since inception through December 31,
2020, the Company has incurred cumulative net losses of $646.3 million. Management expects to incur additional losses in the future to fund its operations
and conduct product research and development and recognizes the need to raise additional capital to fully implement its business plan.

97

Table of Contents

The Company intends to raise additional capital through the issuance of equity securities, debt financings or other sources in order to further

implement its business plan. However, if such financing is not available at adequate levels, the Company will need to reevaluate its operating plan and may
be required to delay the development of its product candidates. The Company expects that its cash and cash equivalents and investments will be sufficient
to fund its operations for at least the next 12 months from the date the Company’s Annual Report on Form 10-K is filed with the Securities and Exchange
Commission (SEC).

The Company cannot at this time predict the specific extent, duration, or full impact that the ongoing COVID-19 pandemic will have on its

financial condition and operations, including ongoing and planned clinical trials. The impact of the COVID-19 pandemic on the financial performance of
the Company will depend on future developments, including the duration and spread of the pandemic and related governmental advisories and restrictions.
These developments and the impact of the COVID-19 pandemic on the financial markets and the overall economy are highly uncertain. If business
conditions, financial markets and/or the overall economy are impacted for an extended period, the Company’s results may be adversely affected.

Basis of Presentation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the

United States of America (GAAP).

In June 2020, the Company formed a wholly-owned, Netherlands-based subsidiary, Allogene Therapeutics, B.V., to help prepare for and assist

with the Company's activities in Europe. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All
material intercompany balances and transactions have been eliminated during consolidation.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that

affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements
and the reported amounts of expenses during the reporting period. Significant estimates and assumptions made in the accompanying consolidated financial
statements include but are not limited to the fair value of common stock, the fair value of stock options, the fair value of investments, the fair value of
convertible notes payable upon conversion, income tax uncertainties, and certain accruals. The Company evaluates its estimates and assumptions on an
ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances change. Actual
results could differ from those estimates.

Concentration of Credit and other Risks and Uncertainties

Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist primarily of cash and cash

equivalents and investments. The primary objectives for the Company’s investment portfolio are the preservation of capital and the maintenance of
liquidity. The Company does not enter into any investment transaction for trading or speculative purposes.

The Company’s investment policy limits investments to certain types of instruments such as certificates of deposit, commercial paper, money

market instruments, obligations issued by the U.S. government and U.S. government agencies as well as corporate debt securities, and places restrictions on
maturities and concentration by type and issuer. The Company maintains cash balances in excess of amounts insured by the FDIC and concentrated within
a limited number of financial institutions. The accounts are monitored by management and management believes that the financial institutions are
financially sound, and, accordingly, minimal credit risk exists with respect to these financial institutions. As of December 31, 2020 and 2019, the Company
has not experienced any credit losses in such accounts or investments.

The Company is subject to a number of risks common for early-stage biopharmaceutical companies including, but not limited to, dependency on

the clinical and commercial success of its product candidates, ability to obtain regulatory approval of its product candidates, the need for substantial
additional financing to achieve its goals, uncertainty of broad adoption of its approved products, if any, by physicians and patients, significant competition
and untested manufacturing capabilities.

Segments

98

Table of Contents

Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed

by the Chief Operating Decision Maker (CODM) in deciding how to allocate resources to an individual segment and in assessing performance. The
Company’s CODM is its Chief Executive Officer. The Company has determined it operates in a single operating segment and has one reportable segment.

Cash, Cash Equivalents and Restricted Cash

The Company considers all highly liquid investments purchased with original maturities of three months or less from the purchase date to be

cash equivalents. Cash equivalents consist primarily of amounts invested in bank money market accounts and money market mutual funds.

The Company has issued letters of credit under separate lease and other agreements which have been collateralized by restricted cash. This cash

is classified as long-term restricted cash on the accompanying consolidated balance sheet based on the terms of the underlying agreements.

Investments

Investments are available-for-sale and are carried at estimated fair value. The Company’s valuations of marketable securities are generally

derived from independent pricing services based upon quoted prices in active markets for similar securities, with prices adjusted for yield and number of
days to maturity, or based on industry models using data inputs, such as interest rates and prices that can be directly observed or corroborated in active
markets. Management determines the appropriate classification of its investments in debt securities at the time of purchase and at the end of each reporting
period. Investments with original maturities of less than three months at the date of purchase are classified as cash and cash equivalents. Investments with
original maturities beyond three months at the date of purchase and which mature at, or less than twelve months from the consolidated balance sheet date
are classified as current.

Unrealized gains and losses are excluded from earnings and are reported as a component of other comprehensive income. The Company

periodically evaluates whether declines in fair values of its available-for-sale securities below their book value are other-than-temporary. This evaluation
consists of several qualitative and quantitative factors regarding the severity and duration of the unrealized loss as well as the Company’s ability and intent
to hold the available-for-sale security until a forecasted recovery occurs. Additionally, the Company assesses whether it has plans to sell the security or it is
more likely than not it will be required to sell any available-for-sale securities before recovery of its amortized cost basis. Realized gains and losses and
declines in fair value judged to be other than temporary, if any, on available-for-sale securities are included in interest and other income, net. The cost of
investments sold is based on the specific-identification method. Interest income on investments is included in interest and other income, net.

Fair Value Measurement

Assets and liabilities recorded at fair value on a recurring basis in the consolidated balance sheets are categorized based upon the level of

judgment associated with the inputs used to measure their fair values. Fair value is defined as the exchange price that would be received for an asset or an
exit price that would be paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between
market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize
the use of unobservable inputs. The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair
value measurements as follows:

Level 1—Observable inputs such as unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.

Level 2—Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the asset or liability. These include

quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

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.

Property and Equipment, Net

Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is computed on a straight-line basis over

the estimated useful lives of the related assets, generally three to seven years. Maintenance and

99

Table of Contents

repairs are charged to operations as incurred. Upon sale or retirement of assets, the cost and related accumulated depreciation are removed from the
consolidated balance sheet and the resulting gain or loss is reflected in other expense.

The Company has determined the estimated life of assets to be as follows:

Laboratory equipment
Computer equipment and purchased software
Fixtures and furniture
Leasehold improvements

5 years
3 - 5 years
7 years
Shorter of lease term or useful life

The Company adopted Accounting Standards Update ("ASU") No. 2018-15, Intangibles – Goodwill and other – Internal-Use Software (Subtopic

350-40) on January 1, 2020 on a prospective basis. The Company capitalizes implementation costs associated with internal use cloud computing
arrangements in alignment with ASC 350-40 internal-use software. Costs incurred in preliminary project stage and post implementation stage are expensed
as incurred. Costs incurred during the application development stage of implementation are capitalized in other long term assets on the consolidated
balance sheet. Capitalized implementation costs from cloud computing arrangements are amortized over the term of the cloud-based service arrangement.

Leases

The Company early adopted ASU No. 2016-2, Leases on January 1, 2018. For its long-term operating leases, the Company recognizes a right-
of-use asset and a lease liability on its consolidated balance sheets. The lease liability is determined as the present value of future lease payments using an
estimated rate of interest that the Company would pay to borrow equivalent funds on a collateralized basis at the lease commencement date. The right-of-
use asset is based on the liability adjusted for any prepaid or deferred rent. The lease term at the commencement date is determined by considering whether
renewal options and termination options are reasonably assured of exercise.

Rent expense for the operating lease is recognized on a straight-line basis over the lease term and is included in operating expenses on the

consolidated statements of operations and comprehensive loss. Variable lease payments include lease operating expenses.

The Company elected to exclude from its consolidated balance sheets recognition of leases having a term of 12 months or less (short-term

leases) and elected to not separate lease components and non-lease components for its long-term real-estate leases.

Equity Method Investments

The Company uses the equity method of accounting for equity investments in companies if the investment provides the ability to exercise
significant influence, but not control, over operating and financial policies of the investee. The Company's proportionate share of the net income or loss of
these companies is included in other expenses in the consolidated statement of operations. Judgment regarding the level of influence over each equity
method investment includes considering key factors such as our ownership interest, representation on the board of directors, participation in policy-making
decisions and material purchase and sale transactions.

The Company evaluates equity method investments for impairment whenever events or changes in circumstances indicate that the carrying

amount of the investment might not be recoverable. Factors considered when reviewing an equity method investment for impairment include the length of
time (duration) and the extent (severity) to which the fair value of the equity method investment has been less than cost, the investee’s financial condition
and near-term prospects and the intent and ability to hold the investment for a period of time sufficient to allow for anticipated recovery. An impairment
that is other-than-temporary is recognized in the period identified.

Variable Interest Entities

For entities in which the Company has variable interests, the Company focuses on identifying if one of the entities is the primary beneficiary

through having the power to direct the activities that most significantly impact the variable interest entity’s economic performance and having the
obligation to absorb losses or the right to receive benefits from the variable

100

Table of Contents

interest entity. If the Company is the primary beneficiary of a variable interest entity, the assets, liabilities, and results of operations of the variable interest
entity will be included in the Company’s consolidated financial statements. The Company did not consolidate any variable interest entities in any of the
periods presented because the Company determined that it was not the primary beneficiary.

Accrued Research and Development Costs

The Company records accrued liabilities for estimated costs of research and development activities conducted by collaboration partners and

third-party service providers, which include the conduct of preclinical studies and clinical trials, and contract manufacturing activities. The Company
records the estimated costs of research and development activities based upon the estimated amount of services provided but not yet invoiced and includes
these costs in accrued and other current liabilities on the consolidated balance sheets and within research and development expenses on the consolidated
statements of operations and comprehensive loss.

The Company accrues for these costs based on factors such as estimates of the work completed and in accordance with agreements established

with its collaboration partners and third-party service providers. The Company makes significant judgments and estimates in determining the accrued
liabilities balance at the end of each reporting period. As actual costs become known, the Company adjusts its accrued liabilities. The Company has not
experienced any material differences between accrued costs and actual costs incurred since its inception.

Income Taxes

Income taxes are accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities are determined based
on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences
are expected to affect taxable income. Management makes an assessment of the likelihood that the resulting deferred tax assets will be realized. A valuation
allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. Due to the Company’s historical
operating performance and net losses, the net deferred tax assets have been fully offset by a valuation allowance.

The Company recognizes uncertain income tax positions at the largest amount that is more likely than not to be sustained upon audit by the

relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Changes in
recognition or measurement are reflected in the period in which judgment occurs. The Company’s policy is to recognize interest and penalties related to the
underpayment of income taxes as a component of the provision for income taxes.

Stock-Based Compensation

The Company measures its stock-based awards granted to employees, consultants and directors based on the estimated fair values of the awards
and recognizes the compensation over the requisite service period. The Company uses the Black-Scholes option-pricing model to estimate the fair value of
its stock-based awards. Stock-based compensation is recognized using the straight-line method. As the stock compensation expense is based on awards
ultimately expected to vest, it is reduced by forfeitures. The Company accounts for forfeitures as they occur.

Net Loss Per Share

Basic net loss per share is calculated by dividing the net loss by the weighted-average number of shares of common stock outstanding for the
period, without consideration for potential dilutive shares of common stock. Since the Company was in a loss position for all periods presented, basic net
loss per share is the same as diluted net loss per share since the effects of potentially dilutive securities are antidilutive. Shares of common stock subject to
repurchase are excluded from the weighted-average shares.

Comprehensive Loss

Comprehensive loss includes net loss and certain changes in stockholders’ equity (deficit) that are excluded from net loss. For the years ended

December 31, 2020, 2019 and 2018 this was comprised of unrealized gains and losses, net of tax, on the Company’s investments.

Definite-Lived Intangible Assets

101

Table of Contents

Identifiable intangible assets consist of in-process research and development and workforce associated with the Pfizer asset acquisition.

Intangible assets with finite lives are amortized over their estimated useful lives on a straight-line basis, generally two years. Acquired in-process research
and development intangible assets with no alternative future use are charged to research and development expense when acquired. The straight-line method
of amortization represents the Company’s best estimate of the distribution of the economic value of the identifiable intangible assets. Intangible assets are
carried at cost less accumulated amortization. Amortization of intangible assets is included in research and development expenses.

Impairment of Long-Lived Assets

Long-lived assets are reviewed annually for impairment or whenever events or changes in circumstances indicate that the carrying amount of an
asset may not be recoverable. Recoverability is measured by comparison of the carrying amount of an asset group to the future net undiscounted cash flows
that the assets are expected to generate. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which
the carrying amount of the assets exceeds the projected discounted future net cash flows arising from the asset. There were impairment losses related to
equipment disposals of zero and $0.2 million for the years ended December 31, 2020 and 2019, respectively.

Revenue Recognition

In the near future, the Company’s revenue is anticipated to be generated through collaboration research and license agreements. The terms of

these agreements are anticipated to contain multiple deliverables which may include (i) grant of licenses, (ii) transfer of know-how, (iii) research and
development activities, (iii) clinical manufacturing and, (iv) product supply. The payment terms of these agreements may include nonrefundable upfront
fees, payments for research and development activities, payments based upon the achievement of certain milestones, royalty payments based on product
sales derived from the collaboration, and payments for supplying product.

The Company will analyze its collaboration arrangements to assess whether they are within the scope of ASC 808, Collaborative Arrangements
(ASC 808) to determine whether such arrangements involve joint operating activities performed by parties that are both active participants in the activities
and exposed to significant risks and rewards dependent on the commercial success of such activities. This assessment is performed throughout the life of
the arrangement based on changes in the responsibilities of all parties in the arrangement. For collaboration arrangements within the scope of ASC 808 that
contain multiple elements, the Company first determines which elements of the collaboration are deemed to be within the scope of ASC 808 and those that
are more reflective of a vendor-customer relationship and, therefore, within the scope of Topic 606, Revenue from Contracts with Customers (ASC 606).
For elements of collaboration arrangements that are accounted for pursuant to ASC 808, an appropriate recognition method is determined and applied
consistently, generally by analogy to Topic 606.

For  elements  of  those  arrangements  that  the  Company  determines  should  be  accounted  for  under  ASC  606,  the  Company  assesses  which
activities in the collaboration agreements are performance obligations that should be accounted for separately and determine the transaction price of the
arrangement,  which  includes  the  assessment  of  the  probability  of  achievement  of  future  milestones  and  other  potential  consideration.  A  performance
obligation represents a promise in a contract to transfer a distinct good or service to a customer, which represents a unit of accounting in accordance with
ASC 606. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own
or together with other resources that are readily available to the customer and is separately identified in the contract. The Company considers a performance
obligation satisfied once the Company has transferred control of a good or service to the customer, meaning the customer has the ability to use and obtain
the benefit of the good or service. A portion of the consideration should be allocated to each distinct performance obligation and recognized as revenue
when, or as, the performance obligation is satisfied. The total consideration which the Company expects to collect in exchange for the Company’s products
is an estimate and may be fixed or variable. The Company constrains the estimated variable consideration when it assesses it is probable that a significant
reversal in the amount of cumulative revenue recognized may occur in future periods. The transaction price is re-evaluated, including the estimated variable
consideration included in the transaction price and all constrained amounts, in each reporting period and as uncertain events are resolved or other changes
in circumstances occur. The allocation of the transaction price is performed based on standalone selling prices, which are based on estimated amounts that
the  Company  would  charge  for  a  performance  obligation  if  it  were  sold  separately.  Revenue  is  recognized  when,  or  as,  performance  obligations  in  the
contracts are satisfied, in the amount reflecting the expected consideration to be received from the goods or services transferred to the customers. Funds
received in advance are recorded as deferred revenue and are recognized as the related performance obligation is satisfied.

Research and Development Expenses

102

Table of Contents

Research and development costs are expensed as incurred and consist of salaries and benefits, including associated stock-based compensation, and

laboratory supplies and facility costs, as well as fees paid to other entities that conduct certain research and development activities on the Company’s
behalf. Research and development expenses also include costs incurred for internal and sponsored collaborative research and development activities. Costs
associated with co-development activities performed under the various license and collaboration agreements are included in research and development
expenses.

Nonrefundable advance payments for goods or services to be received in the future for use in research and development activities are capitalized

and then expensed as the related goods are delivered or the services are performed.

Note 2. Recent Accounting Guidance

Recently Adopted Accounting Pronouncements

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments and

also issued subsequent amendments to the initial guidance: ASU 2018-19, ASU 2019-04, ASU 2019-05, and ASU 2019-11. The standard requires
measurement and recognition of expected credit losses for financial assets by requiring an allowance to be recorded as an offset to the amortized cost of
such assets. For available-for-sale debt securities, expected credit losses should be estimated when the fair value of the debt securities is below their
associated amortized costs. This standard became effective for fiscal years beginning after December 15, 2019, with early adoption permitted beginning the
first quarter of 2019. The Company’s financial instruments that are in the scope of ASU 2016-13 include, but are not limited to, other receivables and
available-for-sale debt securities. The Company adopted this standard on January 1, 2020 and applied the modified retrospective approach. Adoption of the
new guidance had no significant impact on the Company’s consolidated financial statements.

In August 2018, the FASB issued Accounting Standards Update No. 2018-15, Intangibles – Goodwill and other – Internal-Use Software (Subtopic

350-40), which amended its guidance for costs of implementing a cloud computing service arrangement and aligns the requirements for capitalizing
implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to
develop or obtain internal-use software. This new standard also requires customers to expense the capitalized implementation costs of a hosting
arrangement that is a service contract over the term of the hosting arrangement. This standard became effective for fiscal years beginning after December
15, 2019, with early adoption permitted. The Company adopted this standard on January 1, 2020, on a prospective basis for applicable implementation
costs. As of December 31, 2020, $4.2 million of implementation costs related to cloud computing service arrangements were capitalized and included in
other long term assets on the consolidated balance sheets.

In November 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and
Topic 606, which clarifies that certain transactions between participants in a collaborative arrangement should be accounted for under ASC 606 when the
counterparty is a customer. In addition, Topic 808 precludes an entity from presenting consideration from a transaction in a collaborative arrangement as
revenue from contracts with customers if the counterparty is not a customer for that transaction. This standard is effective for fiscal years beginning after
December 31, 2019, with early adoption permitted. The Company adopted this standard on January 1, 2020. Adoption of the new guidance had no
significant impact on the Company’s consolidated financial statements.

In December 2019, the FASB issued Accounting Standards Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for
Income Taxes (ASU 2019-12), which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies
certain aspects of the current guidance to promote consistency among reporting entities. This standard is effective for fiscal years beginning after December
15, 2020, with early adoption permitted. The Company early adopted this standard as of January 1, 2020 on a prospective basis in accordance with ASC
250, Accounting Changes and Error Corrections. The adoption resulted in the Company no longer needing to determine the tax effect from unrealized gains
on available for sale securities, which previously had been disclosed in the consolidated statement of operations as a benefit from income taxes. Adoption
of the new guidance had no significant impact on the Company's consolidated financial statements.

In January 2020, the FASB issues Accounting Standard Update No. 2020-01, Investments – Equity Securities (Topic 321), Investments – Equity
Method  and  Joint  Ventures  (Topic  323), which  clarifies  the  interactions  between  topics  321  and  323  in  applying  or  discontinuing  the  equity  method  of
accounting for investments. This guidance will be effective for the Company in the first quarter of 2021, and early adoption is permitted. The Company is
currently evaluating the impact of the new guidance on its consolidated financial statements.

Note 3. Fair Value Measurements

The Company follows authoritative accounting guidance, which among other things, defines fair value, establishes a consistent framework for

measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis.
Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between
market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use
in pricing an asset or liability.

The Company measures and reports its cash equivalents, restricted cash, investments and convertible notes payable at fair value.

Money market funds are measured at fair value on a recurring basis using quoted prices and are classified as Level 1. Investments are measured at
fair value based on inputs other than quoted prices that are derived from observable market data and are classified as Level 2 inputs, except for investments
in U.S. treasury securities which are classified as Level 1.

There were no Level 3 assets or liabilities at December 31, 2020 or 2019.

Financial assets subject to fair value measurements on a recurring basis and the level of inputs used in such measurements by major security type

as of December 31, 2020 are presented in the following table:

The Company believes that it is more-likely-than-not that investments in an unrealized loss position will be held until maturity and all interest and
principal will be received. The Company does not intent to sell these investments and it is not more likely than not that the Company will be required to sell
the investment before recovery of its amortized cost basis.

The fair values of available-for-sale debt investments by contractual maturity as of December 31, 2020 and 2019 were as follows:

As of December 31, 2020 and 2019, the remaining contractual maturities of available-for-sale securities were less than three years and two years,
respectively. There have been no significant realized losses on available-for-sale securities for the years ended December 31, 2020, 2019 and 2018. As of
December 31, 2020 and 2019, unrealized losses on available-for-sale investments are not attributed to credit risk. The Company believes that it is more-
likely-than-not that investments in an unrealized loss position will be held until maturity and all interest and principal will be received. The Company
believes that an allowance for credit losses is unnecessary because the unrealized losses on certain of the Company’s marketable securities are due to
market factors. As of December 31, 2020 and 2019, securities with a fair value of $5.0 million and zero respectively, were in a net unrealized loss position
for more than 12 months. To date, the Company has not recorded any impairment charges on marketable securities.

As of December 31, 2020 and 2019, the Company recognized $2.8 million and $2.4 million of accrued interest receivable from available-for-sale

investments within prepaid expenses and other current assets on the consolidated balance sheets.

In April 2018, the Company entered into an Asset Contribution Agreement (the Pfizer Agreement) with Pfizer pursuant to which the Company

acquired certain assets, including certain contracts described in Note 7, and intellectual property for the development and administration of chimeric
antigen receptor (CAR) T cells for the treatment of cancer.

As consideration for the purchased assets, the Company issued Pfizer 3,187,772 shares of its Series A-1 convertible preferred stock with an
estimated fair value of $111.8 million or $35.06 per share. The Company also incurred $2.1 million of direct expenses related to the asset acquisition,
bringing the total consideration to $113.9 million. The fair value of the Series A-1 convertible preferred stock was established using the price per share paid
by third-party investors in the concurrent closing of the Series A and A-1 convertible preferred stock financing at $35.06 per share as well as the price per
share paid by Pfizer to purchase additional shares of Series A-1 convertible preferred stock at $35.06 per share at the same time and at the same price per
share as the rest of Series A and A-1 shares sold in such financing (see Note 11 for additional details). The Series A-1 convertible preferred shares issued to
Pfizer had the same rights, preferences and privileges as the Series A convertible preferred shares issued to the third-party investors.

The Company accounted for the transaction as an asset acquisition as substantially all of the estimated fair value of the gross assets acquired was

concentrated in a single identified asset, anti-CD19 CAR T cell therapy, thus satisfying the requirements of the screen test in ASU 2017-1. The assets
acquired in the transaction were measured based on the fair value of the Series A-1 convertible preferred stock issued to Pfizer and direct transaction costs
of $2.1 million, as the fair value of the equity given was more readily determinable than the fair value of the assets received. The following table
summarizes the fair value of assets acquired (in thousands):

113,900 

The estimated fair values of anti-CD19 CAR T cell therapy and anti-BCMA CAR T cell therapy were determined using a risk-adjusted discounted
cash flow approach, which used the present value of the direct cash flows expected to be generated by anti-CD19 CAR T cell therapy and anti-BCMA CAR
T cell therapy during their estimated economic lives, net of returns on contributory assets such as working capital, property and equipment, and the
assembled workforce. The discount rate of 16.5% was based on rates of return available from alternative investments of similar type and quality as of the
valuation date. The remaining IPR&D targets were determined to be more conceptual in nature with nominal value being attributed to them. The estimate
of the fair value of the assembled workforce was determined using a replacement cost approach, based on the estimated cost of recruiting and training an
equivalent workforce as of the acquisition date.

The amount allocated to intangible IPR&D assets was charged to research and development expenses as these assets had no alternative future use
at the time of the acquisition transaction. The remaining intangible asset relates to the assembled workforce which was capitalized and is being amortized
over its estimated economic life of two years to research and development expenses.

In addition, under the terms of the Pfizer Agreement, the Company was also required to make milestone payments to Pfizer of $30.0 million or

$60.0 million per target (depending on the target, and up to $840.0 million in the aggregate for all targets) upon successful completion of certain regulatory
and sales milestones for certain targets covered by the Pfizer Agreement. No milestone payments were made or became due in the years ended
December 31, 2020, 2019 and 2018. These contingent payments were not part of the consideration for the purchased assets.

As part of the asset acquisition, the Company also assumed licensing agreements Pfizer had entered into with two third-party entities holding
certain intellectual property. Both agreements cover use of the intellectual property held by the parties and certain research collaboration activities. See
Note 7 for additional details on these agreements.

Under the Pfizer Agreement, the Company was required to use commercially reasonable efforts to develop and seek regulatory approval in and for

the United States and the European Union for certain products covered by the Pfizer Agreement and to commercialize each product covered by the Pfizer
Agreement in the applicable royalty territory in which regulatory approval for such product has been obtained.

Note 7. License and Collaboration Agreements

Asset Contribution Agreement with Pfizer

In connection with the Pfizer Agreement (see Note 6), the Company is required to make milestone payments upon successful completion of

regulatory and sales milestones on a target-by-target basis for the targets including CD19 and B-cell maturation antigen (BCMA), covered by the Pfizer
Agreement. The aggregate potential milestone payments upon successful completion of various regulatory milestones in the United States and the
European Union are $30.0 million or $60.0 million, depending on the target, with aggregate potential regulatory and development milestones of up to
$840.0 million, provided that the Company is not obligated to pay a milestone for regulatory approval in the European Union for an anti-CD19 allogeneic
CAR T cell product, to the extent Servier has commercial rights to such territory. The aggregate potential milestone payments upon reaching certain annual
net sales thresholds in North America, Europe, Asia, Australia and Oceania (the Territory) for a certain number of targets covered by the Pfizer Agreement
are $325.0 million per target. The sales milestones in the foregoing sentence are payable on a country-by-country basis until the last to expire of any Pfizer
Royalty Term, as described below, for any product in such country in the Territory. In October 2019, the Territory was expanded to all countries in the
world. No milestone or royalty payments were made in the years ended December 31, 2020, 2019 and 2018.

Pfizer is also eligible to receive, on a product-by-product and country-by-country basis, royalties in single-digit percentages on annual net sales for
products covered by the Pfizer Agreement or that use certain Pfizer intellectual property and for which an IND is first filed on or before April 6, 2023. The
Company’s royalty obligation with respect to a given product in a given country begins upon the first sale of such product in such country and ends on the
later of (i) expiration of the last claim of any applicable patent or (ii) 12 years from the first sale of such product in such country.

Research Collaboration and License Agreement with Cellectis

As part of the Pfizer Agreement (see Note 6), Pfizer assigned to the Company a Research Collaboration and License Agreement (the Original

Cellectis Agreement) with Cellectis S.A. (Cellectis). On March 8, 2019, the Company entered into a License Agreement (the Cellectis Agreement) with
Cellectis. In connection with the execution of the Cellectis Agreement, on March 8, 2019, the Company and Cellectis also entered into a letter agreement
(the Letter Agreement), pursuant to which the Company and Cellectis agreed to terminate the Original Cellectis Agreement. The Original Cellectis
Agreement included a research collaboration to conduct discovery and pre-clinical development activities to generate CAR T cells directed at targets
selected by each party, which was completed in June 2018.

Pursuant to the Cellectis Agreement, Cellectis granted to the Company an exclusive, worldwide, royalty-bearing license, on a target-by-target

basis, with sublicensing rights under certain conditions, under certain of Cellectis’s intellectual property, including its TALEN and electroporation
technology, to make, use, sell, import, and otherwise exploit and commercialize CAR T products directed at certain targets, including BCMA, FLT3, DLL3
and CD70 (the Allogene Targets), for human oncologic therapeutic, diagnostic, prophylactic and prognostic purposes. In addition, certain Cellectis
intellectual property rights granted by Cellectis to the Company and to Servier pursuant to the Exclusive License and Collaboration Agreement by and
between Servier and Pfizer, dated October 30, 2016, which Pfizer assigned to the Company in April 2018, will survive the termination of the Original
Cellectis Agreement.

Pursuant to the Cellectis Agreement, the Company granted Cellectis a non-exclusive, worldwide, royalty-free, perpetual and irrevocable license,

with sublicensing rights under certain conditions, under certain of the Company's intellectual

108

Table of Contents

property, to make, use, sell, import and otherwise commercialize CAR T products directed at certain targets (the Cellectis Targets).

The Cellectis Agreement provides for development and sales milestone payments by the Company of up to $185.0 million per product that is

directed against an Allogene Target, with aggregate potential development and sales milestone payments totaling up to $2.8 billion. Cellectis is also eligible
to receive tiered royalties on annual worldwide net sales of any products that are commercialized by the Company that contain or incorporate, are made
using or are claimed or covered by, Cellectis intellectual property licensed to the Company under the Cellectis Agreement (the Allogene Products), at rates
in the high single-digit percentages. Such royalties may be reduced, on a licensed product-by-licensed product and country-by-country basis, for generic
entry and for payments due under licenses of third party patents. Pursuant to the Cellectis Agreement, and subject to certain exceptions, the Company is
required to indemnify Cellectis against all third party claims related to the development, manufacturing, commercialization or use of any Allogene Product
or arising out of the Company’s material breach of the representations, warranties or covenants set forth in the Cellectis Agreement, and Cellectis is
required, subject to certain exceptions, to indemnify the Company against all third party claims related to the development, manufacturing,
commercialization or use of CAR T products directed at Cellectis Targets or arising out of Cellectis’s material breach of the representations, warranties or
covenants set forth in the Cellectis Agreement.

The royalties are payable, on a licensed product-by-licensed product and country-by-country basis, until the later of (i) the expiration of the last to

expire of the licensed patents covering such product; (ii) the loss of regulatory exclusivity afforded such product in such country, and (iii) the tenth
anniversary of the date of the first commercial sale of such product in such country; however, in no event shall such royalties be payable, with respect to a
particular licensed product, past the twentieth anniversary of the first commercial sale for such product.

Depending on the Cellectis Target, the Company has a right of first refusal or right of first negotiation to purchase or license from Cellectis rights

to develop and commercialize products against such Cellectis Targets.

Under the Cellectis Agreement, the Company has certain diligence obligations to progress the development of CAR T product candidates and to

commercialize one CAR T product per Allogene Target in one major market country where the Company has received regulatory approval. If the Company
materially breaches any of its diligence obligations and fails to cure within 90 days, then with respect to certain targets, such target will cease to be an
Allogene Target and instead will become a Cellectis Target.

Unless earlier terminated in accordance with its terms, the Cellectis Agreement will expire on a product-by-product and country-by-country basis,

upon expiration of all royalty payment obligations with respect to such licensed product in such country. The Company has the right to terminate the
Cellectis Agreement at will upon 60 days’ prior written notice, either in its entirety or on a target-by-target basis. Either party may terminate the Cellectis
Agreement, in its entirety or on a target-by-target basis, upon 90 days’ prior written notice in the event of the other party’s uncured material breach. The
Cellectis Agreement may also be terminated by the Company upon written notice at any time in the event that Cellectis becomes bankrupt or insolvent or
upon written notice within 60 days of a consummation of a change of control of Cellectis.

All costs the Company incurred in connection with this agreement were recognized as research and development expenses in the consolidated

statement of operations. For the year ended December 31, 2019, $5.0 million of costs were incurred related to the achievement of a clinical development
milestone under this agreement. No clinical development milestones were achieved for the years ended December 31, 2020 and 2018.

License and Collaboration Agreement with Servier

As part of the Pfizer Agreement (see Note 6), Pfizer assigned to the Company an Exclusive License and Collaboration Agreement (the Servier

Agreement), with Les Laboratoires Servier SAS and Institut de Recherches Internationales Servier SAS (collectively, Servier) to develop, manufacture and
commercialize certain allogeneic anti-CD19 CAR T cell product candidates, including UCART19, in the United States with the option to obtain the rights
over additional anti-CD19 product candidates and for allogeneic CAR T cell product candidates directed against one additional target. In October 2019, the
Company agreed to waive its rights to the one additional target.

Under the Servier Agreement, the Company has an exclusive license to develop, manufacture and commercialize UCART19 in the field of anti-

tumor adoptive immunotherapy in the United States, with an exclusive option to obtain the same rights for additional product candidates in the United
States and, if Servier does not elect to pursue development or commercialization of those product candidates in certain markets outside of the United States
pursuant to its license, outside of the United States as well. The Company is not required to make any additional payments to Servier to exercise an option.
If the

109

Table of Contents

Company opts-in to another product candidate, Servier has the right to obtain rights to such product candidate outside the United States and to share
development costs for such product candidate.

Under the Servier Agreement, the Company is required to use commercially reasonable efforts to develop and obtain marketing approval in the

United States in the field of anti-tumor adoptive immunotherapy for at least one product directed against CD19, and Servier is required to use commercially
reasonable efforts to develop and obtain marketing approval in the European Union, and one other country in a group of specified countries outside of the
European Union and the United States, in the field of anti-tumor adoptive immunotherapy for at least one allogeneic adaptive T cell product directed
against a certain Company-selected target.

For product candidates that the Company is co-developing with Servier, including UCART19, ALLO-501 and ALLO-501A, the Company is
responsible for 60% of the specified development costs and Servier is responsible for the remaining 40% of the specified development costs under the
applicable global research and development plan. Subject to certain restrictions, each party has the right to conduct activities that are specific to its territory
outside the global research and development plan at such party’s sole expense. In addition, each party is solely responsible for commercialization activities
in its territory at such party’s sole expense.

The Company is required to make milestone payments to Servier upon successful completion of regulatory and sales milestones. The Servier

Agreement provides for aggregate potential payments by the Company to Servier of up to $137.5 million upon successful completion of various regulatory
milestones, and aggregate potential payments by the Company to Servier of up to $78.0 million upon successful completion of various sales milestones.
Similarly, Servier is required to make milestone payments upon successful completion of regulatory and sales milestones for products directed at the
Allogene-target covered by the Servier Agreement that achieves such milestones. The total potential payments that Servier is obligated to make to the
Company under the Servier Agreement upon successful completion of regulatory and sales milestones are $42 million and €70.5 million ($86.6 million),
respectively. The foregoing milestones are subject to certain adjustments if the Company obtains rights for certain products outside of the United States
upon Servier’s election not to pursue such rights.

Each party is also eligible to receive tiered royalties on annual net sales in countries within the paying party’s respective territory of any licensed
products that are commercialized by such party that are directed at the targets licensed by such party under the Servier Agreement. The royalty rates are in
a range from the low tens to the high teen percentages. Such royalties may be reduced for interchangeable drug entry, expiration of patent rights and
amounts paid pursuant to licenses of third-party patents. The royalty obligation for each party with respect to a given licensed product in a given country in
each party’s respective territory (the Servier Royalty Term) begins upon the first commercial sale of such product in such country and ends after a defined
number of years.

Unless earlier terminated in accordance with the Servier Agreement, the Servier Agreement will continue, on a licensed product-by-licensed

product and country-by-country basis, until the Servier Royalty Term with respect to the sale of such licensed product in such country expires.

For the year ended December 31, 2020, the Company recorded $8.5 million of net cost recoveries under the cost-sharing terms as a reduction to

research and development expenses. For the years ended December 31, 2019 and 2018, the Company recorded $7.3 million and $4.2 million, respectively,
of costs incurred under the collaboration agreement with Servier as research and development expenses. As of December 31, 2020, amounts due from
Servier of $3.8 million were recorded in other current assets in the accompanying consolidated balance sheets. As of December 31, 2019, amounts due to
Servier of $2.2 million were recorded in accrued and other current liabilities in the accompanying consolidated balance sheets.

Research Collaboration and License Agreement with Notch Therapeutics

On November 1, 2019, the Company entered into a Collaboration and License Agreement (the Notch Agreement) with Notch Therapeutics Inc.

(Notch), pursuant to which Notch granted to Allogene an exclusive, worldwide, royalty-bearing, sublicensable license under certain of Notch’s intellectual
property to develop, make, use, sell, import, and otherwise commercialize therapeutic gene-edited T cell and/or natural killer (NK) cell products from
induced pluripotent stem cells directed at certain CAR targets for initial application in non-Hodgkin lymphoma, acute lymphoblastic leukemia and multiple
myeloma. In addition, Notch has granted Allogene an option to add certain specified targets to its exclusive license in exchange for an agreed per-target
option fee.

The Notch Agreement includes a research collaboration to conduct research and pre-clinical development activities to generate engineered cells

directed to Allogene’s exclusive targets, which will be conducted in accordance with an agreed research plan and budget under the oversight of a joint
development committee. Allogene will reimburse Notch’s costs incurred

110

Table of Contents

in accordance with such plan and budget. The term of the research collaboration will expire upon the earlier of (i) the fifth anniversary of the date of the
Notch Agreement, (ii) at Allogene’s election, following the joint development committee’s determination that for each exclusive target, Notch has met
certain success criteria, or (iii) the joint development committee’s determination that the research collaboration cannot be reasonably pursued against any
exclusive target due to technical infeasibility or safety issues.

In connection with the execution of the Notch Agreement, Allogene made an upfront payment to Notch of $10.0 million in return for a license to

access Notch's technology in order to conduct research pursuant to the Notch Agreement. The Company recognized a research and development expense of
$10 million during the year ended December 31, 2019 as the license had no foreseeable alternative future use. In addition, Allogene made a $5.0 million
investment in Notch’s series seed convertible preferred stock, resulting in Allogene having a 25% ownership interest in Notch’s outstanding capital stock
on a fully diluted basis immediately following the investment. In connection with this investment, David Chang, M.D., Ph.D., the Company's President,
Chief Executive Officer and Board member, was appointed to Notch’s board of directors.

Under the Notch Agreement, Notch will be eligible to receive up to $7.25 million upon achieving certain agreed research milestones, up to $4.0

million per exclusive target upon achieving certain pre-clinical development milestones, and up to $283.0 million per exclusive target and cell type (i.e., T
cell or NK cell) upon achieving certain clinical, regulatory and commercial milestones. Notch is also entitled to receive tiered royalties in the mid to high
single digit range on Allogene’s sales of licensed products, subject to certain reductions, for a term, on a country-by-country and product-by-product basis,
commencing on first commercial sale of such product in such country and continuing until the latest of (i) the date upon which there is no valid claim of the
licensed patents in such country of sale that covers such product, (ii) the expiration of applicable data or other regulatory exclusivity in such country of sale
or (iii) a defined period from the first commercial sale of such product in such country.

The terms of the Notch Agreement will continue on a product-by-product and country-by-country basis until Allogene’s payment obligations with

respect to such product in such country have expired. Following such expiration, Allogene’s license with respect to such product and country shall be
perpetual, irrevocable, fully paid up and royalty-free. Allogene may terminate the Collaboration Agreement in whole or on a product-by-product basis upon
ninety days’ prior written notice to Notch. Either party may also terminate the Collaboration Agreement with written notice upon material breach by the
other party, if such breach has not been cured within a defined period of receiving such notice, or in the event of the other party’s insolvency.

The Company has determined that Notch is a variable interest entity as of December 31, 2020 and 2019, respectively. The Company does not have

the power to direct the activities which most significantly affect Notch's economic performance. Accordingly, for the years ended December 31, 2020 and
2019, the Company did not consolidate Notch because the Company determined that it was not the primary beneficiary.

For the years ended December 31, 2020 and 2019, the Company recorded $3.2 million and $0.1 million, respectively, in collaboration costs as

research and development expenses.

Strategic Alliance with The University of Texas MD Anderson Cancer Center

On October 6, 2020, the Company entered into a strategic five-year collaboration agreement with The University of Texas MD Anderson Cancer

Center (MD Anderson) for the preclinical and clinical investigation of allogeneic CAR T cell product candidates. The Company and MD Anderson are
collaborating on the design and conduct of preclinical and clinical studies with oversight from a joint steering committee.

Under the terms of the agreement, the Company has committed up to $15.0 million of funding for the duration of the agreement. Payment of this

funding is contingent on mutual agreement to study orders in order for any study to be included under the alliance. The Company made an upfront payment
of $3.0 million to MD Anderson in the year ended December 31, 2020. The Company is obligated to make further payments to MD Anderson each year
upon the anniversary of the agreement effective date through the duration of the agreement term. These costs are expensed to research and development as
MD Anderson renders the services under the strategic alliance. As of December 31, 2020, no research and development costs had been incurred under the
alliance.

The agreement may be terminated by either party for material breach by the other party. Individual studies may be terminated for, among other

things, material breach, health and safety concerns or where the institutional review board, the review board at the clinical site with oversight of the clinical
study, requests termination of any study. Where any legal or regulatory authorization is finally withdrawn or terminated, the relevant study will also
terminate automatically.

Joint Venture and License Agreement with Allogene Overland Biopharm (CY) Limited

On December 14, 2020, the Company entered into a License Agreement with Allogene Overland Biopharm (CY) Limited (Allogene Overland), a
joint venture established by the Company and Overland Pharmaceuticals (CY) Inc. (Overland), pursuant to a Share Purchase Agreement, dated December
14, 2020, for the purpose of developing, manufacturing and commercializing certain allogeneic CAR T cell therapies for patients in greater China, Taiwan,
South Korea and Singapore (the JV Territory).

Pursuant to the Share Purchase Agreement, the Company acquired Seed Preferred Shares in Allogene Overland representing 49% of Allogene

Overland's outstanding stock as partial consideration for the License Agreement, and Overland acquired Seed Preferred Shares representing 51% of
Allogene Overland's outstanding stock for $117.0 million in upfront and certain quarterly cash payments, to support operations of Allogene Overland. As
of December 31, 2020, the Company and Overland are the sole equity holders in Allogene Overland. The Company received $40 million from Allogene
Overland as partial consideration for the License Agreement.

Pursuant to the License Agreement, the Company granted Allogene Overland an exclusive license to develop, manufacture and commercialize
certain allogeneic CAR T cell candidates directed at four targets, BCMA, CD70, FLT3, and DLL3, in the JV Territory. As consideration, the Company
would also be entitled to additional regulatory milestone payments of up to $40.0 million and, subject to certain conditions, tiered low-to-mid single-digit
sales royalties.

Promises that the Company concluded were distinct performance obligations in the License Agreement included: (1) the license of intellectual

property and delivery of know-how, (2) the manufacturing license, related know-how and support, (3) if and when available know-how developed in future
periods, and (4) participation in the joint steering committee.

In order to determine the transaction price, the Company evaluated all the payments to be received during the duration of the contract. Fixed

consideration exists in the form of the upfront payment. Regulatory milestones and royalties were considered variable consideration. The Company
constrains the estimated variable consideration when it assesses it is probable that a significant reversal in the amount of cumulative revenue recognized
may occur in future periods. Milestone fees were constrained and not included in the transaction price due to the uncertainties of research and development.
The Company re-evaluates the transaction price, including the estimated variable consideration included in the transaction price and all constrained
amounts, in each reporting period and as uncertain events are resolved or other changes in circumstances occur. The shares of Series Seed Preferred Stock
were accounted for as part of the Company’s joint venture and equity method accounting upon formation of the joint venture, and as such, were excluded
from the transaction price. The Company determined that the initial transaction price consists of the upfront payment of $40.0 million. The allocation of the
transaction price is performed based on standalone selling prices, which are based on estimated amounts that the Company would charge for a performance
obligation if it were sold separately. The transaction price allocated to the license of intellectual property and delivery of know-how will be recognized
upon grant of license and delivery of know-how. The transaction price allocated to (i) the manufacturing license, related know-how and support services,
(ii) if and when available know-how developed in future periods, and (iii) participation in the joint steering committee, will be recognized over time as the
services are delivered. Funds received in advance are recorded as deferred revenue and will be recognized as the performance obligations are satisfied.

The Company has determined that Allogene Overland is a variable interest entity as of December 31, 2020. The Company does not have the

power to independently direct the activities which most significantly affect Allogene Overland's economic performance. Accordingly, for the year ended
December 31, 2020, the Company did not consolidate Allogene Overland because the Company determined that it was not the primary beneficiary.

For the year ended December 31, 2020, the Company recorded the $40.0 million upfront cash payment received from Allogene Overland as

deferred revenue, of which $39.0 million was current, on the consolidated balance sheet.

Rent expense for short-term leases was $0.2 million, $2.4 million and $2.6 million for the years ended December 31, 2020, 2019 and 2018

respectively.

Certain lease agreements require the Company to return designated areas of leased space to its original condition upon termination of the lease

agreement. At the inception of such leases, the Company records an asset retirement obligation and a corresponding capital asset in an amount equal to the
estimated fair value of the obligation. To determine the fair value of the obligation, we estimate the cost for a third-party to perform the restoration work. In
subsequent periods, for each asset retirement obligation, the Company records interest expense to accrete the asset retirement obligation liability to full
value and depreciate each capitalized asset retirement obligation asset, both over the term of the associated lease agreement. Asset retirement obligations
were $0.5 million and $0.4 million as of December 31, 2020 and 2019 respectively.

Other Commitments

Solar Power Purchase and Energy Services Agreement

In July 2020, the Company entered into a Solar Power Purchase and Energy Services Agreement for the installation and operation of a solar

photovoltaic generating system and battery energy storage system at the Company's cell therapy manufacturing facility in Newark, California. The
agreement has a term of 20 years and is expected to commence in the first half of 2021. The Company is obligated to pay for electricity generated from the
system at an agreed rate for the duration of the agreement term. Termination of the agreement by the Company will result in a termination payment due of
approximately $4.3 million. In connection with the agreement, the Company maintains a letter of credit for the benefit of the service provider in the amount
of $4.3 million which is disclosed as restricted cash in the consolidated balance sheet as of December 31, 2020.

License Agreements for Intellectual Property

The Company has entered into certain license agreements for intellectual property which is used as part of our development and manufacturing
processes. Each of these respective agreements are generally cancellable by the Company. These agreements require payment of annual license fees and
may include conditional milestone payments for achievement of specific research, clinical and commercial events, and royalty payments. The timing and
likelihood of any significant conditional milestone payments or royalty payments becoming due was not probable as of December 31, 2020.

Purchase Commitments

In the normal course of business, the Company enters into various purchase commitments with third-party contract manufacturers for the
manufacture and processing of our product candidates and related raw materials, and we have entered into other contracts in the normal course of business
with contract research organizations for clinical trials and other vendors for other services and products for operating purposes. These agreements generally
provide for termination or cancellation, other than for costs already incurred. As of December 31, 2020, the Company had non-cancellable purchase
commitments of $5.4 million.

Contingencies

In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and
provide for general indemnifications. The Company’s exposure under these agreements is unknown, because it involves claims that may be made against
the Company in the future, but have not yet been made. The Company accrues a liability for such matters when it is probable that future expenditures will
be made and such expenditures can be reasonably estimated.

Indemnification

In accordance with the Company’s amended and restated certificate of incorporation and amended and restated bylaws, the Company has

indemnification obligations to its officers and directors for certain events or occurrences, subject to certain limits, while they are serving in such
capacity. There have been no claims to date, and the Company has a directors and officers liability insurance policy that may enable it to recover a portion
of any amounts paid for future claims.

Company acquiring shares of Notch’s Series Seed convertible preferred stock for a total investment cost of $5.1 million which includes transaction costs of
$0.1 million, resulting in a 25% ownership interest in Notch.

The Company’s total equity investment in Notch as of December 31, 2020 and 2019 was $3.7 million and $4.9 million, respectively, based on the

cost method of accounting. During the years ended December 31, 2020 and 2019, the Company recognized its share of Notch's net loss under the other
expenses caption within the consolidated statement of operations.

Allogene Overland Biopharm (CY) Limited

In conjunction with the execution of the License Agreement with Allogene Overland (see Note 7), the Company also entered into a Share
Purchase Agreement and Shareholders' Agreement with the joint venture company acquiring shares of Allogene Overland’s Seed Preferred Shares
representing a 49% ownership interest in exchange for entering into a License Agreement which had a carrying value of zero. The Company accounts for
its investment in Allogene Overland as an equity method investment at carrying value. The Company's total equity investment is Allogene Overland was
zero as of December 31, 2020.

The Company’s equity investment in Allogene Overland as of December 31, 2020 had a zero carryover basis. Therefore, the Company did not

account for its share of losses incurred by Allogene Overland. See Note 7 for further details.

Note 10. Convertible Notes Payable (2018 Notes)

In September 2018, the Company entered into a note purchase agreement pursuant to which it sold and issued an aggregate of $120.2 million in

convertible promissory notes (convertible notes payable or 2018 Notes) and received net cash proceeds of $116.8 million. On issuance, the fair value of the
2018 Notes was determined to be equal to $120.2 million, which is the principal amount of the 2018 Notes.

The 2018 Notes did not accrue interest. The 2018 Notes were settled in 7,856,176 shares of common stock in connection with the closing of the

Company’s IPO (see Note 1) at a settlement price equal to 85% of the IPO price per share.

On issuance, the Company elected to account for the 2018 Notes at fair value with any changes in estimated fair value being recognized through

the statements of operations and comprehensive loss until the 2018 Notes settled. The fair value of the 2018 Notes was determined to be $141.4 million
upon settlement. For the years ended December 31, 2020 and 2019, the Company recognized zero and $21.2 million, respectively, of expense in the
accompanying statements of operations and comprehensive loss for the change in fair value of the 2018 Notes. On issuance, total debt issuance costs of
$3.4 million were expensed and recognized as interest expense in the accompanying statements of operations and comprehensive loss.

Note 11. Convertible Preferred Stock and Stockholders’ Equity

Convertible Preferred Stock

As discussed in Note 6, the Company issued 3,187,772 shares of its Series A-1 convertible preferred stock to Pfizer in connection with the Pfizer

Agreement entered into in April 2018.

received in July and August 2018, at the election of the Company’s board of directors.

On the completion of the IPO (see Note 1), all outstanding shares of convertible preferred stock were automatically converted into 61,655,922

shares of common stock.

Preferred Stock

Pursuant to the Amended and Restated Certificate of Incorporation filed on October 15, 2018, as amended, the Company is authorized to issue a

total of 10,000,000 shares of preferred stock, of which no shares were issued and outstanding at December 31, 2020 and 2019.

Common Stock

Pursuant to the Amended and Restated Certificate of Incorporation filed on October 15, 2018, as amended, the Company is authorized to issue a

total of 200,000,000 shares of common stock, of which 140,474,305 and 124,267,358 shares were issued and outstanding at December 31, 2020 and 2019,
respectively.

In connection with the issuance of the Company’s Series A convertible preferred stock in April 2018, the Company’s founders agreed to modify
their common shares outstanding to include vesting provisions that require continued service to the Company in order to vest in those shares. As such, the
26,249,993 modified shares of common stock became compensatory upon such modification. The total compensation cost resulting from the modification
is approximately $59.5 million and is being recognized over the four year vesting term.

Common stockholders are entitled to dividends if and when declared by the Company’s Board of Directors subject to the prior rights of the
preferred stockholders. As of December 31, 2020 and 2019, no dividends on common stock had been declared by the Company’s Board of Directors.

Note 12. Stock-Based Compensation

2018 Equity Incentive Plan

In June 2018, the Company adopted its 2018 Equity Incentive Plan (Prior 2018 Plan). The 2018 Plan provided for the Company to sell or issue

common stock or restricted common stock, or to grant incentive stock options or nonqualified stock options for the purchase of common stock, to
employees, members of the Company’s Board of Directors and consultants of the Company under terms and provisions established by the Company’s
Board of Directors. In September 2018, the Board of Directors adopted a new amended and restated 2018 Equity Incentive Plan as a successor to and
continuation of the Prior 2018 Plan, which became effective in October 2018 (the 2018 Plan), which authorized additional shares for issuance and provided
for an automatic annual increase to the number of shares issuable under the 2018 Plan by an amount equal to 5% of the total number of shares of common
stock outstanding on December 31st of the preceding calendar year. The term of any stock option granted under the 2018 Plan cannot exceed 10 years. The
Company generally grants stock-based awards with service conditions only. Options granted typically vest over a four-year period but may be granted with
different vesting terms. Restricted Stock Units granted typically vest annually over a four-year period but may be granted with different vesting terms.
Options shall not have an exercise price less than 100% of the fair market value of the Company’s common stock on the grant date. If the individual
possesses more than 10% of the combined voting power of all classes of stock of the Company, the exercise price shall not be less than 110% of the fair
market value of a common share of stock on the date of grant. This requirement is applicable to incentive stock options only.

As of December 31, 2020 and 2019, there were 12,308,848 and 9,642,503 shares reserved by the Company under the 2018 Plan for the future

issuance of equity awards.

The  aggregate  intrinsic  values  of  options  exercised,  outstanding,  exercisable,  vested  and  expected  to  vest  were  calculated  as  the  difference
between the exercise price of the options and the closing price of the Company’s common stock on the Nasdaq Global Select Market on December 31,
2020. During the years ended December 31, 2020 and 2019, the estimated weighted-average grant-date fair value of employee options granted was $13.79
per share and $18.42 per share, respectively. As of December 31, 2020 and 2019, there was $81.1 million and $74.7 million, respectively, of unrecognized
stock-based compensation related to unvested stock options, which is expected to be recognized over a weighted-average period of 2 years, 222 days and 3
years, 15 days, respectively.

The fair value of employee, consultant and director stock option awards was estimated at the date of grant using a Black-Scholes option-pricing

model with the following assumptions:

Fair value of common stock
Expected term in years
Expected volatility
Expected risk-free interest rate
Expected dividend

Year Ended December 31,

2020
$18.22 - $48.94
5.31 - 6.09

5.27 - 6.08
74.14% - 74.92%
1.54% - 2.62%
0%

The Black-Scholes option-pricing model requires the use of subjective assumptions which determine the fair value of stock-based awards. These

assumptions include:

Fair value of common stock—For grants before October 2018 when the Company was private and there was no public market for the Company’s
common stock, the fair value of the Company’s common stock underlying share-based awards was estimated on each grant date by the Company’s Board
of Directors. In order to determine the fair value of the Company’s common stock underlying option grants, the Company’s Board of Directors considered,
among other things, valuations of the Company’s common stock prepared by an unrelated third-party valuation firm in accordance with the guidance
provided by the American Institute of Certified Public Accountants Practice Guide, Valuation of Privately-Held-Company Equity Securities Issued as
Compensation. For all grants subsequent to the Company’s IPO in October 2018, the fair value of common stock was determined by taking the closing
price per share of common stock per Nasdaq.

Expected term— The expected term represents the period that stock-based awards are expected to be outstanding. The expected term for option

grants is determined 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 stock-based awards.

Expected volatility— The Company uses an average historical stock price volatility of comparable public companies within the biotechnology and

pharmaceutical industry that were deemed to be representative of future stock price trends as the Company does not have sufficient trading history for its
common stock. The Company will continue to apply this process until a sufficient amount of historical information regarding the volatility of its own stock
price becomes available.

Risk-free interest rate—The risk-free interest rate is based on the U.S. Treasury zero coupon issues in effect at the time of grant for periods

corresponding with the expected term of option.

Expected dividend—The Company has never paid dividends on its common stock and has no plans to pay dividends on its common stock.

Therefore, the Company used an expected dividend yield of zero.

For the years ended December 31, 2020 and 2019, total stock-based compensation expense related to stock options was $31.8 million and $21.9

million, respectively.

    For the years ended December 31, 2020 and 2019, the Company granted zero and 57,361 performance based restricted stock units to a certain executive
officer pursuant to the 2018 Plan. The 2019 granted performance awards are subject to the holder's continued service to the Company through each
applicable vesting event. Through December 31, 2020, the Company believes that the achievement of the requisite performance conditions for these awards
are not probable and as a result, no compensation expense has been recognized related to these awards in the year ended December 31, 2020.

For the years ended December 31, 2020 and 2019, total stock-based compensation expense related to restricted stock units was $17.2 million and

$8.8 million, respectively. As of December 31, 2020 and 2019, there was $51.1 million and $43.0 million, respectively, of unrecognized stock-based
compensation which is expected to be recognized over a weighted average period of 2.84 years.

Employee Stock Purchase Plan

In October 2018, the shareholders approved the 2018 Employee Stock Purchase Plan (ESPP), which initially reserved 1,160,000 shares of our

common stock for employee purchases under terms and provisions established by the Board of Directors. Effective January 1, 2020 and 2019, the number
of shares authorized under the ESPP for employee purchases increased by 1,242,673 and 1,214,826 shares respectively. The ESPP is intended to qualify as
an ‘employee stock purchase plan’ under Section 423 of the Internal Revenue Code. Under the current offering adopted pursuant to the ESPP, each offering
period is approximately 24 months, which is generally divided into four purchase periods of approximately six months.

Employees are eligible to participate if they are employed by the Company. Under the ESPP, employees may purchase common stock through

payroll deductions at a price equal to 85% of the lower of the fair market value of common stock on the first trading day of each offering period or on the
purchase date. The ESPP provides for consecutive, overlapping 24-month offering periods. The offering periods are scheduled to start on the first trading
day on or after March 16 or September 16 of each year, except for the first offering period which commenced on October 11, 2018, the first trading day
after the effective date of the Company’s registration statement. Contributions under the ESPP are limited to a maximum of 15% of an employee’s eligible
compensation.

The fair values of the rights granted under the ESPP were calculated using the following assumptions:

The Company allows certain of its employees and its directors to exercise options granted under the Prior 2018 Plan and the 2018 Plan prior to

vesting. The shares related to early exercised stock options are subject to the Company’s lapsing repurchase right upon termination of employment or
service on the Company’s Board of Directors at the lesser of the original purchase price or fair market value at the time of repurchase. In order to vest, the
holders are required to provide continued service to the Company. The proceeds are initially recorded in accrued and other liabilities and other long-term
liabilities for the noncurrent portion. The proceeds are reclassified to paid-in capital as the repurchase right lapses. During the years ended December 31,
2020 and 2019, zero options were early exercised. As of December 31, 2020 and 2019, there was $2.8 million and $2.8 million recorded in accrued and
other liabilities and $1.1 million and $3.9 million recorded in other long-term liabilities related to shares held by employees and directors that were subject
to repurchase. The underlying shares are shown as outstanding in the consolidated financial statements since the exercise date but the shares which are
subject to future vesting conditions are not included in the calculation of earnings per share.

incurred net operating losses for all the periods presented. The Company has not reflected any benefit of such net operating loss carryforwards in the
accompanying consolidated financial statements.

The Company has established a full valuation allowance against its deferred tax assets due to the uncertainty surrounding the realization of such

assets.

Deferred income taxes reflect the net tax effects of (a) temporary differences between the carrying amounts of assets and liabilities for financial

reporting purposes and the amounts used for income tax purposes, and (b) operating losses and tax credit carryforwards.

Realization of deferred tax assets is dependent upon future earnings, if any, the timing and amount of which are uncertain.  Due to the lack of
earnings history, the net deferred tax assets have been fully offset by a valuation allowance. The valuation allowance increased by approximately $72.5
million, $50.0 million and $41.9 million during the years ended December 31, 2020, 2019 and 2018, respectively.

Current federal and California tax laws include substantial restrictions on the utilization of NOLs and tax credit carryforwards in the event of an

ownership change of a corporation. Accordingly, the Company's ability to utilize NOLs and tax credit carryforwards may be limited as a result of such
ownership changes. Such a limitation could result in the expiration of carryforwards before they are utilized.

In December 2019, the FASB issued Accounting Standards Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for

Income Taxes (ASU 2019-12), which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and
clarifies certain aspects of the current guidance to promote consistency among reporting entities. This guidance will be effective for the Company in the
first quarter of 2021 on a prospective basis, and early adoption is permitted. The Company early adopted this standard as of January 1, 2020 on a
prospective basis in accordance with ASC 250, Accounting Changes and Error Corrections. The adoption resulted in the Company no longer needing to
determine the tax effect from unrealized gains on available for sale securities, which previously had been disclosed in the consolidated statement of
operations as a benefit from income taxes. The impact of the adoption is that the benefit from income taxes in the consolidated statement of operations and
comprehensive loss is zero. For the years ended December 31,

122

 
 
 
 
 
 
Table of Contents

2019 and 2018, the Company recorded a tax benefit of $0.3 million and $0.1 million respectively, in other comprehensive income, related to available-for-
sale securities.

We apply the provisions of ASC Topic 740 to account for uncertain income tax positions.  A reconciliation of the beginning and ending amount of

unrecognized tax benefits is as follows:

Balance at beginning of the year:

Additions based on tax positions related to current year
Additions to tax position of prior year
Reductions to tax position of prior years
Lapse of the applicable statute of limitations

Balance at end of the year

It is the Company’s policy to include penalties and interest expense related to income taxes as a component of interest and other income, net, as

necessary. As of December 31, 2020, 2019 and 2018, there were no accrued interest and penalties related to uncertain tax positions. The reversal of the
uncertain tax benefits would not affect the effective tax rate to the extent that the Company continues to maintain a full valuation allowance against its
deferred tax assets. Unrecognized tax benefits may change during the next 12 months for items that arise in the ordinary course of business.  We are subject
to examination by U.S. federal or state tax authorities for all years since inception.

Item 9A. Controls and Procedures.

Conclusions Regarding the Effectiveness of Disclosure Controls and Procedures

As of December 31, 2020, management, with the participation of our Chief Executive Officer and Chief Financial Officer, performed an

evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the
Exchange Act. Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports we file or submit
under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such
information is accumulated and communicated to our management, including the Chief Executive Officer and the Chief Financial Officer, to allow timely
decisions regarding required disclosures.

Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control
objective and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on this
evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2020, the design and operation of our disclosure
controls and procedures were effective at a reasonable assurance level.

Management’s Annual Report on Internal Controls Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in
Exchange Act Rule 13a-15(f). Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial
reporting and the preparation of consolidated financial statements for external purposes in accordance with generally accepted accounting principles.
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.

Management has assessed the effectiveness of our internal control over financial reporting based on the framework set forth by the Committee of

Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013 framework). Based on our evaluation,
management has concluded that our internal control over financial reporting was effective as of December 31, 2020.

The effectiveness of our internal control over financial reporting has been audited by Ernst & Young LLP, an independent registered public

accounting firm, as stated in their attestation report herein, which expresses an unqualified opinion on the effectiveness of our internal control over
financial reporting as of December 31, 2020.

Inherent Limitations of Internal Controls

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 risks that controls may become inadequate because of changes in conditions, or that the
degree of compliance with the policies or procedures may deteriorate.

Changes in Internal Control over Financial Reporting

We regularly review our system of internal control over financial reporting and make changes to our processes and systems to improve controls
and increase efficiency, while ensuring that we maintain an effective internal control environment. Changes may include such activities as implementing
new, more efficient systems, consolidating activities, and migrating processes. There were no changes in our internal control over financial reporting that
occurred during the most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control
over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Allogene Therapeutic, Inc.

Opinion on Internal Control Over Financial Reporting

We have audited Allogene Therapeutic, Inc.’s internal control over financial reporting as of December 31, 2020, based on criteria established in

Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the
COSO criteria). In our opinion, Allogene Therapeutic, Inc. (the Company) maintained, in all material respects, effective internal control over financial
reporting as of December 31, 2020, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the 2020
consolidated financial statements of the Company and our report dated February 25, 2021 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the

effectiveness of internal control over financial reporting included in the accompanying Management’s 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.

Equity Compensation

Equity awards will be granted under the Company’s Amended and Restated 2018 Equity Incentive Plan (the “Plan”),

(a)

Automatic Equity Grants.

(i)

Initial Grant for New Directors. Without any further action of the Board, each person who, after the IPO,

is elected or appointed for the first time to be a Non-Employee Director will automatically, upon the date of his or her initial
election or appointment to be a Non- Employee Director (or, if such date is not a market trading day, the first market trading day
thereafter), be granted (i) a Nonstatutory Stock Option to purchase shares of common stock of the Company (the “Initial Option
Grant”) and (ii) a restricted stock unit award covering shares of common stock of the Company (the “Initial RSU Grant”),
whereby the Initial Option Grant and Initial RSU Grant shall together have a total grant date value of $850,000 (with the shares
covered by the award rounded down to the nearest whole share). The recipient shall designate the proportionate share between
the Initial Option Grant and Initial RSU Grant prior to or on the date of grant. The grant date value will be calculated in
accordance with the Black-Scholes option valuation methodology or such other methodology as the Board or the Compensation
Committee of the Board may determine prior to the grant of such award. Each Initial Option Grant will vest in a series of 36
successive equal monthly installments over the three-year period measured from the date of grant. Each Initial RSU Grant will
vest in a series of three successive equal annual installments over the three-year period measured from the date of grant.

(ii) Annual Grant. Without any further action of the Board, at the close of business on the date of each
Annual Meeting following the IPO, each person who is then a Non- Employee Director will automatically be granted (i) a
Nonstatutory Stock Option to purchase shares of common stock (the “Annual Option Grant”) and (ii) a restricted stock unit
award covering shares of common stock of the Company (the “Annual RSU Grant”), whereby the Annual Option Grant and
Annual RSU Grant shall together have a total grant date value of $425,000 (with the shares covered by the award rounded down
to the nearest whole share). The recipient shall designate the proportionate share between the Annual Option Grant and Annual
RSU Grant prior to or on the date of grant. The grant date value will be calculated in accordance with the Black-Scholes option
valuation methodology or such other methodology as the Board or the Compensation Committee of the Board may determine
prior to the grant of such award. Each Annual Option Grant will vest in a series of 12 successive equal monthly installments
over the one-year period measured from the date of grant. Each Annual RSU Grant will vest on the one-year anniversary of the
date of grant.

(b) Vesting; Change in Control. All vesting is subject to the Non-Employee Director’s “Continuous Service” (as

defined in the Plan) on each applicable vesting date. Notwithstanding the foregoing vesting schedules, for each Non-Employee
Director who remains in Continuous Service with the Company until immediately prior to the closing of a “Change in Control”
(as defined in the Plan), the shares subject to his or her then-outstanding equity awards that were granted pursuant to this policy
will become fully vested immediately prior to the closing of such Change in Control.

(c) Remaining Terms. The remaining terms and conditions of each award, including transferability, will be as set
forth in the Company’s Director Option Grant Package or Director RSU Grant Package, as applicable, in the forms adopted
from time to time by the Board.

Expenses

The Company will reimburse Non-Employee Director for ordinary, necessary and reasonable out- of-pocket travel expenses to
cover in-person attendance at and participation in Board and committee

2

meetings; provided,  that  the  Non-Employee  Director  timely  submit  to  the  Company  appropriate  documentation  substantiating
such expenses in accordance with the Company’s travel and expense policy, as in effect from time to time.

breach, including without limitation, by promptly terminating such sublicense agreement if such breach is not cured within [***]
days of Licensee becoming aware of such breach. Within [***] days following the grant of any sublicense or any amendment
thereto,  Licensee  shall  provide  Allogene  with  a  complete,  unredacted  copy  of  any  sublicense  agreement  entered  into  with  a

other terms contained therein that are not necessary to ascertain compliance with this Agreement). Licensee shall be liable for the

Confidential Information of the Parties, including in accordance with Article 9; (ii) do not impose any payment obligations or
liability  on  Allogene;  and  (iii)  are  otherwise  consistent  with  the  terms  of  this  Agreement.  Licensee  shall  also  use  reasonable

Affiliate of Licensee with access to or possession of any [***] without Allogene’s prior written consent, which may be granted or
withheld in Allogene’s sole discretion.

(f)

is  reasonably  necessary  or  useful  for  the  Development,  Manufacture  or  Commercialization  of  the  Product  in  the  Field  (such
Patent or Know-How, “Third Party IP”), then such Party shall bring such matter to the attention of the other Party and the Parties
shall  discuss  whether  it  is  advisable  for  the  Parties  to  obtain  a  license  under  Third  Party  IP  for  the  Product  in  the  Licensee

(b)

As  between  the  Parties,  Allogene  shall  have  the  exclusive  right  (but  not  the  obligation)  to  obtain  a
worldwide  license  under  such  Third  Party  IP  for  the  Product;  provided,  Licensee  shall  have  the  right  to  review  and,  provide
comments to terms that are specifically applicable to the Licensee Territory; and provided further, if Allogene fails to exercise
such right promptly, then Licensee may seek to acquire such Third Party IP or obtain a license under such Third Party IP solely
for Licensee's use only in the Licensee Territory. If Allogene (a) acquires such Third Party IP or (b) obtains such a worldwide
license  (each  such  acquisition  or  license,  a  “Third  Party  IP  License”),  such  Third  Party  IP,  to  the  extent  falling  within  the
definition of Allogene Technology, and to the extent Licensee desires to obtain the benefit of such Third Party IP License, shall
be included in Allogene Technology and licensed or sublicensed to Licensee under the terms and conditions of this Agreement;
provided however that Licensee shall be responsible for and reimburse Allogene for (i) [***] percent ([***]%) of the payments

Costs”).

2.8

Existing  Allogene  In-Licenses.  (A)  All  licenses  and  other  rights  granted  to  Licensee  under  this  Article  2
(including any sublicense rights) are subject to the rights and obligations of Allogene under the Existing Allogene In-Licenses,
including the field limitations and rights reserved to Third Parties, including grant back licenses to the licensors set forth therein.
Licensee  shall  comply  with,  and  shall  require  its  Affiliates  and  Sublicensees  to  comply  with,  all  applicable  provisions  of  the

Existing Allogene In-License, or take (or fail to take) any action that would reasonably be expected to (i) permit the Upstream
Licensor to terminate the Existing Allogene In-License or (ii) other than with respect to actions that could invoke Section 4.5 of
Upstream  License  2,  adversely  affect  any  of  Licensee's  exclusive  rights  under  this  Agreement  or  any  Existing  License
Agreement.

2.9

Bundled  Products.  Notwithstanding  any  other  provision  of  this  Agreement,  for  purposes  of  the  license  grant
under Section 2.1 with respect to any Product that is a Bundled Product, such license will only include a license with respect to
the Product component of such Bundled Product.

2.10

Non-Compete. During the Term, Licensee shall not engage, either directly or indirectly, via any of its controlled
Affiliates  (i.e.,  subsidiaries)  or  in  collaboration  with  a  Third  Party,  in  the  research,  Development,  Commercialization,
Manufacturing or sale of [***] or otherwise engage in the exploitation of [***] outside the Products, without Allogene's written
consent.

2.11

647 Product. Licensee shall utilize 647 Product as part of the lymphodepletion regimen for the Development and
Commercialization of the Products unless otherwise agreed by Allogene. Without  Allogene’s  prior  written  consent,  Licensee’s
Development, use or Commercialization of any Product without the use of the 647 Product as part of the regimen shall constitute
a  material  breach  of  this  Agreement.  The  Parties  shall  mutually  agree  on  a  supply  and  quality  agreement  for  647  Product  as
further described in Section 5.2.

Article 3

Overview; Diligence. Licensee shall be solely responsible, at its own costs and expense, for the Development of
the  Products  in  the  Field  in  the  Licensee  Territory.  Licensee  shall  use  Commercially  Reasonable  Efforts  to  (i)  Develop  each
Product in the Field in the Licensee Territory in accordance with the Development Plan (including the timeline set forth therein);
(ii)  perform  the  Development  activities  in  compliance  with  Applicable  Law,  including  GCP  and  cGMP;  and  (iii)  obtain  and
maintain  Regulatory  Approvals  for  the  Products  in  each  jurisdiction  in  the  Licensee  Territory.  Failure  to  use  Commercially
Reasonable Efforts to meet the foregoing obligations shall constitute a material breach of Licensee, which shall entitle Allogene
to terminate this Agreement with respect to the applicable Product in accordance with and subject to the provisions of Section
12.2(a). Licensee will notify the JSC if it reasonably determines that, notwithstanding its Commercially Reasonable Efforts, any
milestone  or  other  requirement  under  the  then  current  Development  Plan  will  unlikely  be  achieved  by  Licensee  in  connection
with  Developing  the  Products,  whether  because  of  changes  in  scientific,  business,  market,  or  other  conditions,  in  each  case
outside of its reasonable control. After such notice, the JSC shall promptly meet, discuss and consider in good faith appropriate
modifications to the Development Plan in light of the changed circumstances.

Development activities to be conducted by or on behalf of Licensee in order to obtain Regulatory Approvals for the applicable
Products  in  the  Field  in  the  Licensee  Territory,  including  (i)  the  non-clinical  and  clinical  trials  as  part  of  the  Development
activities relating to the applicable Products and (ii) the timeline for filing MAAs for the applicable Products for any currently
proposed indication in the Field in each region within the Licensee Territory. After the Effective Date, either Party may propose
to the JSC and the other Party revisions to the Development Plan, and the JSC may from time-to-time amend the Development
Plan. Any and all updates to the Development Plan must be approved by the JSC.

3.3

Global Development Collaborations.

(a)

Global Development Plan. Allogene shall keep the JSC promptly informed on its plans (and any changes
to its plans) for the global Development of each Product in sufficient detail for Licensee to evaluate and consider in good faith
changes that would be necessary to conform the Development of the applicable Product in the Field in the Licensee Territory to
Allogene’s global development plan (the “Global Development Plan”). Except as expressly agreed by Allogene in writing or to
the  extent  required  by  the  applicable  Regulatory  Authority  or  to  address  specific  operational  requirements  in  the  Licensee
Territory, Licensee shall use its reasonable best efforts to ensure that Licensee’s Development Plan, including the study protocols
and  the  Development  of  the  Products  in  the  Field  in  the  Licensee  Territory  shall  all  be  in  full  conformance  with  the  material
aspects of the Global Development Plan.

(b)

The  Parties  shall  reasonably  collaborate  with  respect  to  the  Development  of  the  Product  across  their
territories. Allogene shall have the right to conduct Clinical Trials designed to obtain and maintain Regulatory Approval of the
Product  in  multiple  countries  and  jurisdictions  through  the  conduct  of  Clinical  Trials  in  multiple  sites  in  such  countries  and
jurisdictions  as  part  of  one  unified  Clinical  Trial  or  separately  but  concurrently  in  accordance  with  a  common  Clinical  Trial
protocol (such Clinical Trial, a “Multi-Region Trial”), which may or may not include the Licensee Territory. If Allogene decides
to conduct a Multi-Region Trial for the Product that includes the Licensee Territory, Allogene shall be the sole sponsor of such
Multi-Region  Trial,  the  Parties  shall  mutually  agree  on  the  CRO  that  will  conduct  the  Multi-Region  Trial  in  the  Licensee
Territory, and Licensee shall be responsible for [***] percent ([***]%) of all costs incurred from conducting Multi-Region Trials
in the Licensee Territory, including the cost of clinical sites and trials in the Licensee Territory.

(c)

If  the  Parties  agree  to  conduct  any  Multi-Region  Trial  for  the  Product  including  the  Licensee  Territory,
Allogene  shall  have  the  right  to  control  the  design  and  protocol  for  any  global  Clinical  Trial  of  the  Product  and  shall  offer
Licensee  the  opportunity  to  provide  input  regarding  clinical  study  design,  reasonably  anticipated  timeline  and  conduct  of  the
relevant  clinical  trials  of  the  Product  in  the  Field  in  the  Licensee  Territory,  all  of  which  shall  be  reasonably  considered  by
Allogene.

3.4

Clinical Trial Audit Rights.

-20-

(a)

Clinical Trials. Licensee shall conduct all Clinical Trial of the Products in compliance with all Applicable

Laws, including GCP and regulations promulgated by the NMPA and FDA.

(b)

Conduct  of  Audits.  Upon  [***]  Business  Days’  prior  written  notification  by  Allogene  but  no  more
frequent than once per [***] (except in the event that Allogene has reasonable cause), and based on an audit scope agreed upon
by the Parties, Allogene or its representatives may conduct, at its sole cost and expense, an audit of Licensee or its Affiliates and
all  Clinical  Trial  sites  engaged  by  Licensee  or  its  Affiliates  to  perform  Licensee’s  obligations  under  the  Development  Plan,  in
each  case,  to  ensure  that  the  applicable  Clinical  Trials  are  conducted  in  compliance  with  the  Development  Plan,  GCP,  and
Applicable Laws; provided that in the event any such audit of Licensee’s Clinical Trial sites engaged by Licensee or its Affiliates
requires Licensee’s assistance, Licensee shall provide Allogene or its representatives with such assistance at Licensee’s cost, to
the extent reasonable, including providing personnel of Licensee to be present for such audit and producing any documents or
authorizations allowing Allogene or its representatives to conduct such audit, to the extent reasonable. No later than [***] days
after  the  completion  of  such  audit,  Allogene  shall  provide  Licensee  with  a  written  summary  of  Allogene’s  findings  of  any
deficiencies or other areas of remediation that Allogene identifies during any such audit and the Parties shall promptly meet to
discuss any such deficiencies or other areas of remediation identified by Allogene. Licensee shall use Commercially Reasonable
Efforts to respond or remediate any such deficiencies promptly following Allogene’s receipt of such report.

(c)    Third Party Agreements. Licensee shall include provisions granting Allogene the right to conduct audits set

forth in Section 3.4(b) in Licensee’s agreements with (i) any Third Party related to the conduct of Clinical Trials, and (ii) any

on its behalf in connection with the Development of a Product, including, without limitation, all Clinical Trial data and records,
in each case in accordance with its usual documentation and record retention practices. Such records shall be in sufficient detail
to  properly reflect,  in  a  good  scientific manner,  all  significant  work  done,  and the results of studies and trials undertaken and,
further,  shall  be  at  a  level  of  detail  appropriate  for  patent  and  regulatory  purposes.  Licensee  shall  document  all  non-clinical
studies and Clinical Trials in formal written study reports according to Applicable Laws and national and international guidelines.
Upon Allogene’s reasonable request, Licensee shall, and shall cause its Affiliates and Sublicensees, to provide to Allogene copies
of such records, including, at Allogene’s cost and expense, certified translated copies of such records. All such records, reports,
information and data provided shall be subject to the confidentiality provisions of Article 9.

Development Reports. Licensee shall keep Allogene (by reporting through the JSC) reasonably informed of the
progress  and  results  of  its  and  its  Affiliates’  and  their  respective  sublicensees’  work  under  the  Development  Plan  (including
prompt reporting of available pre-

-21-

clinical and any available and aggregated clinical data collected and cleaned pursuant to Licensee’s development plans). Without
limiting the generality of the foregoing, at each regularly scheduled JSC meeting, Licensee shall provide the JSC with a written
report summarizing the Development activities performed since the last JSC meeting and the results thereof, and comparing such
activities with the Development Plan for such time period at least [***] Business Days prior to the scheduled JSC meeting. Such
reports shall be provided in English and at a level of detail reasonably requested by the JSC and sufficient to enable the JSC to
determine Licensee’s compliance with its diligence obligations under Section 3.1. At such JSC meeting, the JSC members shall
discuss  the  status,  progress  and  results  of  Licensee’s  Development  activities.  Licensee  shall  promptly  respond  to  the  JSC's
reasonable questions or requests for additional information relating to such Development activities. No later than [***] days after
each  anniversary  of  the  Effective  Date,  Licensee  shall  provide  the  JSC  with  a  detailed  written  report  in  English  regarding  the
progress under the Development Plan and results thereof.

3.7

Subcontractors. Licensee  shall  have  the  right  to  engage  subcontractors  to  conduct  any  activities  necessary  for
Development of the Products under this Agreement, provided that Licensee shall (a) provide written notice to Allogene no less
[***]  days  prior  to  engaging  any  such  subcontractors,  and  (b)  ensure  such  subcontractors  are  bound  by  written  obligations  of
confidentiality and non-use consistent with this Agreement and have agreed in writing to assign to Licensee all Data, Know-How,
Inventions or other intellectual property generated by such subcontractor in the course of performing such subcontracted work.
Licensee shall remain responsible for any obligations that have been delegated or subcontracted to any subcontractor, and shall be
responsible for the performance of its subcontractors. Notwithstanding the foregoing, no Third Party subcontractor may obtain
rights under [***].

3.8

Transfer of Allogene Know-How. Within [***] days after the Effective Date, Allogene shall initiate transfer to
Licensee,  at  Allogene’s  sole  cost  and  expense,  all  Allogene  Know-How  (other  than  Know-How  related  to  Manufacturing)  in
Allogene’s  possession  that  is  necessary  or  reasonably  useful  for  the  Development  of  the  [***]  in  the  Licensee  Territory  by
providing copies or samples of relevant documentation and Data of such Allogene Know-How, including data within reports, and
electronic files, that exists on the Effective Date (the “Initial Know-How Transfer”),  which Initial Know-How  Transfer  shall
occur in a manner and following a reasonable schedule established by the JSC. During the Term, Allogene shall (a) within [***]
days of an IND filing relating to the [***], transfer to Licensee, at Allogene’s sole cost and expense, all Allogene Know-How
(other  than  Know-How  related  to  Manufacturing)  in  Allogene’s  possession  that  is  necessary  or  reasonably  useful  for  the
Development  of  the  applicable  Product  in  the  Licensee  Territory,  (b)  provide  Licensee  with  additional  Allogene  Know-How
related to any Compound or Product, to the extent such Allogene Know-How comes to Allogene’s attention (or are reasonably
requested  by  Licensee)  and  have  not  previously  been  provided  to  Licensee,  to  the  extent  necessary  or  reasonably  useful  for
Licensee to exercise its rights or perform its obligations under this Agreement, (c) provide Licensee with reasonable access to
Allogene personnel involved in the Development of Products, either in-person at Allogene’s facility or by teleconference, to the
extent necessary to effect such technology transfer (the “Continuing Know-How Transfer,” and together with the Initial Know-
How Transfer, the “Know-How Transfer”), and (d) promptly deliver to Licensee an updated version of Schedule 1.13 to reflect

-22-

additional Patents that are included in the Allogene Patents (including without limitation, Allogene Invention Patents and Patents
which  no  longer  qualify  as  Acquiror  IP).  For  clarity,  Allogene's  failure  to  transfer  any  Allogene  Know-How  or  to  deliver  any
updated  version  of  Schedule  1.13  as  required  hereunder  shall  not  affect  Licensee's  exclusive  rights  and  licenses  to  use  such
Know-How or practice such Patents in the Licensee Territory pursuant to this Agreement. The  Parties  agree  and  acknowledge
that the Initial Know-How Transfer shall be the materials listed on Schedule 3.8. Notwithstanding anything contained herein to
the  contrary,  the  foregoing  Know-How  Transfer  shall  not  include  any  transfer  of  Manufacturing  technology  with  respect  to  a
Product, which shall be initiated in accordance with Section 5.3(b).

3.9

limitation,  Regulatory  Materials,  the  “Transferred Material”)  that  Allogene  will  transfer  to  Licensee  for  use  pursuant  to  this
Agreement, such transfer shall take place in accordance with the following provisions

(a)    Transferred Materials and related information provided by Allogene shall, as between the Parties, remain the
property of Allogene and shall be kept securely by Licensee and shall not be provided by Licensee to any Third Party (other than
Affiliates, permitted Sublicensees, contractors, and Regulatory Authorities in the Licensee Territory) without the prior written
consent of Allogene.

(b)    Licensee shall only use the Transferred Material pursuant to this Agreement and use the Transferred Materials in

accordance with all Applicable Laws, regulations and governmental guidelines.

(c)    Licensee shall not use the Transferred Material in any human subjects without Allogene’s prior written consent.

(d)    Licensee shall not provide any of the Transferred Material to any Third Party (other than Regulatory Authorities in
the  Licensee  Territory  or  as  otherwise  permitted  under  Section  3.9(a))  without  Allogene’s  prior  written  consent,  and  Licensee
shall  endeavor  in  good  faith  to  ensure  that  such  permitted  Third  Party  comply  with  the  same  restrictions  as  set  forth  in  this
Section 3.9, and Licensee shall be responsible for the breach by any such Third Party of any of the terms of this Agreement as if
such breach were a breach by Licensee.

(e)        Licensee  acknowledges  that  the  Transferred  Material  is  experimental  in  nature  and  provided  “as  is”  and  that
Allogene  makes  no  representation  or  extends  no  warranty  of  any  kind  with  respect  to  the  Transferred  Material  and  hereby
disclaims  all  warranties,  either  express  or  implied,  including,  but  not  limited  to,  any  warranty  of  merchantability,  fitness  for  a
particular purpose or that their use does not or shall not infringe any patent rights of third parties.

(f)    Licensee shall use the Transferred Material at its own risk and shall comply with any safety instructions provided by

Allogene.

-23-

(g)    Licensee shall, at the election of Allogene following completion of the purpose for which the Transferred Material
was  transferred,  destroy  or  return  the  Transferred  Material,  other  than  Transferred  Material  which  has  been  delivered  to
Regulatory Authorities.

(h)    The Transferred Materials shall be identical to those used for the purposes of Product Development, Manufacturing,
marketing authorization and Commercialization by Allogene and its Affiliates and licensees in the Allogene Territory, other than
Transferred Materials consisting of cellular materials and biological samples, in which case such Transferred Materials shall meet
the specifications as agreed to by the Parties in writing.

accordance with Article 5.

Article 4
Regulatory

4.1

Conduct  of  Regulatory  Activities.  Licensee  (itself  and  through  its  Affiliates  and  Sublicensees,  as  applicable)
shall be solely responsible for the expenses and costs of all regulatory activities with respect to the Products in the Field in the
Licensee Territory. Under the oversight of the JSC, Licensee shall implement the regulatory strategy formulated and adopted by
the JSC and prepare, file, obtain and maintain Regulatory Approvals for the Products in the Field in the Licensee Territory, shall
be the holder of all Regulatory Approvals for the Products in the Field in the Licensee Territory, and shall have responsibility for
interactions with Regulatory Authorities with respect to the Products in the Field in the Licensee Territory; provided however that
if Applicable Laws in the Licensee Territory do not allow Licensee to hold Regulatory Approvals for any Product in the Licensee
Territory, then during the Term Allogene shall hold such Regulatory Approval for Licensee’s benefit, shall appoint Licensee or
one of its Affiliates as its exclusive agent to handle all regulatory activities for such Product in the Licensee Territory, and shall
promptly transfer such Regulatory Approval to Licensee or its designee when allowed by Applicable Laws; provided that in the
event  and  during  any  period  that  Allogene  holds  such  Regulatory  Approval  for  Licensee’s  benefit,  (i)  Allogene  shall  not  be
obligated to perform any activities, bear any obligations, or bear any costs, in each case, in addition to the activities set forth in
this Agreement due to Allogene or its Affiliate holding such Regulatory Approval; (ii) Allogene shall not assume any liability in
connection with Allogene holding such Regulatory Approval; (iii) should Allogene incur any costs or expenses related to holding
or  transferring  any  such  Regulatory  Approval,  Licensee  shall  reimburse  Allogene  or  its  Affiliates  for  any  and  all  costs  and
expenses  incurred  by  or  on  behalf  of  Allogene  in  holding  or  transferring  such  Regulatory  Approval;  and  (iv)  Licensee  shall
indemnify  and  hold  Allogene  Indemnitees  (as  defined  herein)  from  and  against  all  Losses  to  the  extent  arising  from  Allogene
holding  such  Regulatory  Approval  in  the  Licensee  Territory  as  set  forth  in  Article  13.  Notwithstanding  anything  in  this
Agreement to the contrary, Licensee may not modify the study protocol, use or indication of a Product without the JSC's prior
written approval. The Parties acknowledge and agree that importation of final Products to the Licensee Territory would reduce
cost and time to Regulatory Approvals. The Parties shall cooperate in good faith to explore importation of final

-24-

Products to the Licensee Territory prior to Product approval. To fulfill the regulatory requirements for regulatory filings in the
Licensee  Territory,  Allogene  shall  use  Commercially  Reasonable  Efforts  to  provide  the  relevant  certification  documents  or
illustration statement with notarization and/or legalization within a reasonable timeline.

4.2

Review of Regulatory Documents. Licensee shall keep Allogene regularly and fully informed of the preparation
and Regulatory Authority review and approval of submissions and communications with Regulatory Authorities with respect to
the  Products  in  the  Field  in  the  Licensee  Territory.  Licensee  shall  provide  to  Allogene  drafts  of  any  material  Regulatory
Documents  in  the  Licensee  Territory  for  the  Products  no  later  than  [***]  days  prior  to  the  planned  submission  (or  promptly
following Licensee’s receipt of such Regulatory Documents, as applicable). Licensee shall consider in good faith any comments
received from Allogene on such Regulatory Documents provided that such comments are received at least [***] Days prior to the
planned submission due date. In addition, Licensee shall notify Allogene of any material Regulatory Documents for the Products
and  any  other  material  documents,  comments  or  other  correspondences  related  thereto  submitted  to  or  received  from  any
Regulatory Authority in the Licensee Territory and shall provide Allogene with electronic copies thereof as soon as reasonably
practicable, but in all events within [***] days after submission or receipt thereof or sooner if required by the Pharmacovigilance
Agreement (as defined below). If any such Regulatory Document is material and is not in English, then, at Allogene’s request and
expense,  Licensee  shall  also  endeavor  in  good  faith  to  provide  Allogene  with  a  written  English  translation  within  the
corresponding  timelines  as  set  forth  in  this  Article  4  (or,  with  respect  to  any  such  Regulatory  Document  that  is  large,  such
additional  period  of  time  as  may  be  reasonably  necessary  for  Licensee  to  obtain  such  translation  or  to  provide  a  summary  in
English).

4.3

Copies  of  Regulatory  Correspondence.  Licensee  shall  notify  Allogene  of  any  comments  or  other
correspondence regarding any Regulatory Documents that are received from any Regulatory Authority in the Licensee Territory
and  shall  provide  Allogene  with  copies  thereof  as  soon  as  practicable,  but  in  all  events  within  [***]  Days  of  receipt  (or,  with
respect  to  any  such  finding,  notice,  or  report  that  is  large,  such  additional  period  of  time  as  may  be  reasonably  necessary  for
Licensee to obtain such translation or to provide a summary in English).

4.4

Notice  of  Meetings.  Licensee  shall  provide  Allogene  with  notice  of  any  meeting  or  discussion  with  any
Regulatory  Authority  in  the  Licensee  Territory  related  to  any  Product  no  later  than  [***]  Days  after  receiving  notice  thereof.
Licensee shall lead any such meeting or discussion and Allogene or its designee shall have the right, but not the obligation, to
attend and participate in any such meeting or discussion at Allogene's or its designee's expense unless prohibited or restricted by
Applicable Law or Regulatory Authority. At Licensee’s request, Allogene shall reasonably cooperate with Licensee in preparing
for any such meeting or discussion. If Allogene elects not to attend such meeting or discussion, then Licensee shall provide to
Allogene a written summary thereof in English promptly following such meeting or discussion.

4.5

Notice  of  Regulatory  Action.  If  any  Regulatory  Authority  takes  or  gives  notice  of  its  intent  to  take  any

regulatory action with respect to any activity of Licensee or Allogene

-25-

relating to any Product, then Licensee or Allogene (as the case may be) shall notify the other Party of such contact, inspection, or
notice  or  action  within  [***]  after  receipt  of  such  notice  (or,  if  action  is  taken  without  notice,  within  [***]  of  Licensee  or
Allogene  (as  the  case  may  be)  becoming  aware  of  such  action).  Allogene  shall  have  the  right  to  review  and  comment  on  any
other responses by Licensee to any such action of a Regulatory Authority that pertain to a Product in the Licensee Territory.

4.6

Access  to  Regulatory  Documents  and  Data.  Allogene  hereby  grants  to  Licensee  (and  its  Affiliates  and
Sublicensees,  as  applicable)  the  right  to  access  and  cross-reference  filings  made  by  Allogene  or  its  Affiliates  with  Regulatory
Authorities  and  regulatory  filings  relating  to  the  Products,  including  the  Data  included  in  such  filings,  solely  to  the  extent
necessary  for  seeking,  obtaining  and  maintaining  Regulatory  Approvals  of  the  Products  in  the  Field  in  the  Licensee  Territory.
Licensee  hereby  grants  to  Allogene  and  its  Affiliates  and  licensees  the  right  to  access  and  cross-reference  filings  made  by
Licensee and its Affiliates and Sublicensees with Regulatory Authorities and regulatory filings relating to the Products, including
the  Data  included  in  such  filings  and  all  corresponding  communications  with  the  Regulatory  Authorities  for  any  regulatory
inquiries or actions taken by the Regulatory Authorities in the Allogene Territory. Licensee may use such right of reference to
Allogene’s regulatory filings in the Field solely for the purpose of seeking, obtaining and maintaining Regulatory Approval of the
Products in Field in the Licensee Territory. Allogene may use the right of reference to Licensee’s regulatory filings solely for the
purpose of seeking, obtaining and maintaining Regulatory Approval of the Products outside or within the Field in the Allogene
Territory. Each Party shall, promptly upon request of the other Party, file with applicable Regulatory Authorities such letters of
access or cross-reference as may be necessary to accomplish the intent of this Section 4.6. If any approval or filing is required by
Applicable Law for a Party to share any materials abovementioned in this Section 4.6 with the other Party, the other Party shall
use  Commercially  Reasonable  Efforts  to  obtain  such  approval  or  filing  at  its  sole  costs  and  expense.  Notwithstanding  the
foregoing,  (A)  neither  Party  shall  be  obligated  to  share  any  personally  identifiable  information  with  the  other  Party,  unless
reasonably required for such other Party to Develop the Products in its respective territory and such sharing is permitted by, and
in  accordance  with,  the  Applicable  Laws,  including  applicable  data  privacy  laws,  in  which  case  the  Parties  shall  enter  into  a
separate agreement to address such exchange of personally identifiable information between the Parties, and (B) each Party shall
only be obligated to share Data on an as-is basis in the then current format.

4.7

Safety Data Exchange. Prior  to  the  Initiation  of  any  Clinical  Trial  of  a  Product  in  the  Licensee  Territory,  the
Parties  shall  negotiate  in  good  faith  and  enter  into  a  safety  data  exchange  agreement  (the  “Pharmacovigilance  Agreement”)
regarding  the  relevant  Compound  and  Product,  which  shall  set  forth  standard  operating  procedures  governing  the  collection,
investigation,  reporting,  and  exchange  of  information  concerning  adverse  drug  reactions/experiences  sufficient  to  permit  each
Party  to  comply  with  its  regulatory  and  other  legal  obligations  within  the  applicable  timeframes.  Such  safety  data  exchange
agreement  shall  identify  which  Party  shall  be  responsible  for  the  timely  reporting  of  all  relevant  adverse  drug
reactions/experiences,  product  quality,  product  complaints  and  safety  data  relating  to  the  Compound  and  Product  to  the
appropriate Regulatory Authorities in the Licensee Territory in accordance with all

-26-

Applicable  Laws.  Such  agreement  shall  allow  each  Party  to  comply  with  all  regulatory  and  legal  requirements  regarding  the
management  of  safety  data  by  providing  for  the  exchange  of  relevant  information  in  the  appropriate  format  within  applicable
timeframes. Unless otherwise mutually agreed by the Parties, Allogene shall maintain a global safety database for the Compound
and Products, and Licensee shall provide all such assistance as Allogene may from time to time require in connection therewith.
Licensee may establish and maintain a local safety database to store the safety information generated from the development of
the Compounds and Products in the Licensee Territory and to assure regulatory reporting compliance in the Licensee Territory.

4.8

Safety and Regulatory Audits. Upon  reasonable  notification  (but  not  less  than  [***]  days),  Allogene  shall  be
entitled to conduct an audit of safety and regulatory systems, procedures and practices of Licensee, including on-site evaluations
to the extent permitting such on-site evaluations is in the control of Licensee. With respect to any inspection of Licensee or its
Affiliates or Sublicensees (including Clinical Trial sites) by any Governmental Authority relating to any Product, Licensee shall
notify Allogene of such inspection (a) no later than [***] Business Day after Licensee receives notice of such inspection or (b)
within [***] Business Day after the completion of any such inspection of which Licensee did not receive prior notice. Licensee
shall  promptly  provide  Allogene  with  all  information  in  Licensee’s  control  related  to  any  such  inspection.  Licensee  shall  also
permit  Governmental  Authorities  outside  of  the  Licensee  Territory  to  conduct  inspections  of  Licensee  or  its  Affiliates  or
Sublicensees  (including  Clinical  Trial  sites)  relating  to  the  Product,  and  shall  ensure  that  all  such  Affiliates  or  Sublicensees
permit  such  inspections.  Allogene  shall  have  the  right,  but  not  the  obligation  (unless  required  by  Applicable  Law  or  any
Governmental  Authority),  to  be  present  at  any  such  inspection  at  its  sole  cost  and  expense.  Following  any  such  regulatory
inspection related to the Products, Licensee shall provide Allogene with (i) an unredacted copy of any finding, notice, or report
provided by any Governmental Authority related to such inspection (to the extent related to the Product) within [***] Business
Days of Licensee receiving the same, and (ii) in the event that such findings, notice, or report is in a language other than English,
a written English translation of any such finding, notice, or report of a Governmental Authority related to such inspection (to the
extent related to the Product) within [***] Business Days after receiving the same (or, with respect to any such finding, notice, or
report  that  is  large,  such  additional  period  of  time  as  may  be  reasonably  necessary  for  Licensee  to  obtain  such  translation  or
provide  such  information  in  another  format  reasonably  agreed  by  the  Parties).  Further  details  including  notification,  timing,
response and scope of such audits shall be included in the Pharmacovigilance Agreement.

4.9

Regulatory  Inspection.  Licensee  shall  promptly  notify  Allogene  of  any  inspection  of  Licensee,  its  Affiliates,
Sublicensees or subcontractors, product manufacture sites and Clinical Trial sites which are out of the Licensee Territory from
any Regulatory Authority relating to the Products or the sites which provide intermediates or excipients or packaging materials to
Licensee,  and  shall  provide  Allogene  with  all  information  pertinent  thereto  (including  all  copies  of  all  notices,  filings  and
correspondences received from or submitted to the Regulatory Authority in connection therewith). Allogene shall have the right,
but  not  the  obligation,  to  be  present  at  any  such  inspection  in  the  Licensee  Territory;  provided,  however,  Allogene  shall  be
responsible for the preparation and conduct of any inspections of manufacturing sites or Clinical Trial sites outside the Licensee
Territory.

-27-

4.10

No Harmful Actions. If Allogene believes that the Licensee is taking or intends to take any action with respect
to  a  Product  that  could  have  a  material  adverse  impact  upon  the  regulatory  status  of  the  Product  in  the  Allogene  Territory,
Allogene shall have the right to bring the matter to the attention of the JSC and the Parties shall discuss in good faith to resolve
such concern. Without limiting the foregoing, unless the Parties otherwise agree: (a) neither Party shall communicate with any
Regulatory  Authority  having  jurisdiction  outside  of  its  respective  territory,  unless  so  ordered  by  such  Regulatory  Authority,  in
which case such Party shall immediately notify the other Party of such order; and (b) neither Party shall submit any Regulatory
Documents  or  seek  Regulatory  Approvals  for  the  Product  outside  of  its  respective  territory,  notify  the  other  Party  of  any
information  it  receives  regarding  any  threatened  or  pending  action,  inspection  or  communication  by  any  Third  Party,  which
would reasonably be expected to affect the safety or efficacy claims of any Product or the continued marketing of any Product (as
to Allogene’s notification obligation, only to the extent it would reasonably be expected to affect the Licensee Territory). Upon
receipt of such information, the Parties shall consult with each other in an effort to arrive at a mutually acceptable procedure for
taking appropriate action with respect to the Licensee Territory, subject to Section 7.1(b).

4.11

Remedial Actions. Each Party shall notify the other immediately, and promptly confirm such notice in writing, if
it obtains information indicating that any Product may be subject to any recall, corrective action or other regulatory action by any
Governmental Authority or Regulatory Authority (as to Allogene’s notification obligation, only to the extent it would reasonably
be  expected  to  affect  the  Licensee  Territory)  (a  “Remedial  Action”).  The  Parties  shall  assist  each  other  in  gathering  and
evaluating  such  information  as  is  necessary  to  determine  the  necessity  of  conducting  a  Remedial  Action  with  respect  to  the
Licensee Territory. Licensee shall bear any all costs and expenses related to any Remedial Action in the Licensee Territory and
shall  have  sole  discretion  with  respect  to  any  matters  relating  to  any  Remedial  Action  in  the  Licensee  Territory,  including  the
decision to commence such Remedial Action and the control over such Remedial Action. Each Party shall, and shall ensure that
its  Affiliates  and  sublicensees  shall,  maintain  adequate  records  to  permit  the  Parties  to  trace  the  distribution  and  use  of  the
Product in the Licensee Territory.

4.12        Territory  Issues.  The  Parties  acknowledge  and  agree  that,  as  of  the  Effective  Date,  the  qualifications,  rights,
obligations,  and  other  requirements  related  to  applying  for,  obtaining,  and  maintaining  Regulatory  Approval  to  Develop,
Manufacture, and Commercialize the Compounds and Products in the Licensee Territory and to enforce the Allogene Technology
in the Licensee Territory, are relatively new, undefined, incomplete, and/or otherwise uncertain. Accordingly, at Licensee’s cost
and  expense,  Allogene  agrees  to  provide  reasonable  cooperation  as  may  be  necessary  for  Licensee  or  an  Affiliate  of  Licensee
(including without limitation, any Affiliate that may be classified by Regulatory Authorities as a wholly foreign-owned enterprise
(“WFOE”)), to be or act as the marketing authorization holder for the Products in the Licensee Territory (“MAH”), to otherwise
receive all of the benefits of being the MAH, and/or to enforce the Allogene Technology in the Licensee Territory.

Responsibilities

Article 6
Commercialization.

. Subject to the terms and conditions of this Agreement (including the diligence obligations set forth below), Licensee (itself and
through its Affiliates and Sublicensees, as applicable) shall be solely responsible for all aspects of the Commercialization of the
Products in the Field in the Licensee Territory, including: (a) developing and executing a commercial launch and pre-launch plan
(the  "Commercialization  Plan"),  (b)  negotiating  with  applicable  Governmental  Authorities  regarding  the  price  and
reimbursement statuses of the Products; provided that Licensee agrees to evaluate and consider in good faith Allogene's concerns
about  Product  pricing  in  the  Licensee  Territory  in  relation  to  the  price  of  the  relevant  Product  sold  in  the  U.S.;  (c)  marketing,
advertising  and  promotion;  (d)  booking  sales  and  distribution  and  performance  of  related  services;  (e)  handling  all  aspects  of
order processing, invoicing and collection, inventory and receivables; (f) providing customer support, including handling medical
queries, and performing other related functions; and (g) conforming its practices and procedures to Applicable Laws relating to
the marketing, detailing and promotion of the Products in the Field in the Licensee Territory. Licensee shall bear all of the costs
and  expenses  incurred  in  connection  with  such  Commercialization  activities.  Licensee  shall  use  Commercially  Reasonable
Efforts to Commercialize the Products in the Licensee Territory after Regulatory Approval for such Product is received and to
expand annual Net Sales of the Products in the Licensee Territory.

-30-

6.2

Compliance with Applicable Laws.

(a)

Licensee shall conduct, and shall cause its Affiliates and Sublicensees to conduct all activities assigned to
it under the Development Plan or with respect to the Products in the Field in and for the Licensee Territory in compliance with all
Applicable Laws (including all applicable data privacy laws, anti-bribery and anti-corruption laws), all applicable national and
international  guidelines  (including  GCP,  GMP,  GLP,  all  applicable  ICH  guidelines  and  other  good  scientific,  laboratory,
manufacturing and clinical practices under the Applicable Laws of the region in which such activities are conducted), and any
Regulatory Authority and Governmental Authority health care programs having jurisdiction in such Party’s respective territory,
each as may be amended from time to time. Licensee shall ensure that its Affiliates and Sublicensees do not transfer or divert the
Compound or Product to an entity other than Licensee, or an entity approved by Licensee, in each case in a manner that would
cause the sale of such Compound or Product in the chain of distribution (from Licensee or its Affiliates or Sublicensees to the end
user) to be excluded (except as an exception provided in the Net Sales definition) in the calculation of Net Sales, provided that
for each unit of the Compound or Product, the inclusion of such sales in the calculation of Net Sales shall occur only once. Upon
reasonable notification, Allogene shall have the rights to conduct audits (but not more than once per Calendar Year, unless for
cause) of Licensee to ensure (i) compliance with applicable cGMP, GCP, GLP, and GSP standards, including on-site evaluations
(to the extent permitting such evaluations is under the control of the audited Party), and (ii) compliance with this Section 6.2.

(b)

Third  Party  Agreements.  Licensee  will  use  Commercially  Reasonable  Efforts  to  include  provisions

granting Allogene the right to conduct the audits set forth in Section 6.2(a) in Licensee’s agreements with its Sublicensees.

6.3

Commercialization  Diligence.  Licensee  shall  be  solely  responsible  for,  and  use  Commercially  Reasonable
Efforts to Commercialize Products in the Field in the Licensee Territory in accordance with the Commercialization Plan, at its
sole cost and expense. For each Product that receives Regulatory Approval in a jurisdiction in the Licensee Territory, Licensee
shall use Commercially Reasonable Efforts to consummate the First Commercial Sale of such Product in such jurisdiction within
[***] months after receipt of such Regulatory Approval. Failure to use Commercially Reasonable Efforts to meet the diligence
obligations set forth in this Section in accordance with the applicable timeline shall constitute a material breach of Licensee such
that Allogene may terminate this Agreement with respect to the relevant Product in accordance with and subject to the provisions
of Section 12.2(a). Licensee will notify the JSC if it reasonably determines that, notwithstanding its Commercially Reasonable
Efforts, any milestone or other requirement under the then current Commercialization Plan will unlikely be achieved by Licensee
in connection with Commercializing the Products, whether because of changes in scientific, business, market, or other conditions,
in each case outside of its reasonable control. After such notice, the JSC shall promptly meet, discuss and consider in good faith
appropriate modifications to the Commercialization Plan in light of the changed circumstances.

6.4

Commercialization  Plan.  The  Commercialization  Plan  shall  contain  in  reasonable  detail  the  major

Commercialization activities and the timelines for achieving such

-31-

activities,  including  marketing  efforts  for  the  Product.  Licensee  shall  deliver  an  initial  Commercialization  Plan  to  the  JSC  for
review and discussion no later than [***] months prior to the anticipated date of the first Regulatory Approval for a Product in
the Licensee Territory. Thereafter, from time to time during the applicable Royalty Term, but at least once every [***] months,
Licensee shall propose updates or amendments to the Commercialization Plan to reflect changes in such plans, including those in
response  to  changes  in  the  marketplace,  relative  success  of  the  Product,  and  other  relevant  factors  influencing  such  plan  and
activities,  and  submit  such  proposed  updated  or  amended  Commercialization  Plan  to  the  JSC.  In  preparing  the  initial
Commercialization  Plan  and  any  updates  or  amendments  thereto,  Licensee  shall  provide  Allogene  with  an  opportunity  to
comment and Licensee shall consider any Allogene’s comments in good faith in finalizing the initial Commercialization Plan and
any updates or amendments thereto.

6.5

Commercialization  Reports.  Each  Calendar  Year  following  receipt  of  the  first  Regulatory  Approval  for  any
Product in any jurisdiction or region in the Licensee Territory, Licensee shall provide to the JSC annually within [***] days after
the end of such Calendar Year during the applicable Royalty Term a written report that summarizes Licensee’s, its Affiliates’ and
Sublicensees’  significant  Commercialization  activities  with  respect  to  the  approved  Products  in  the  Licensee  Territory.  All
updates and reports generated pursuant to this Section 6.5 shall be the Confidential Information of Licensee.

6.6

Global  Branding  Strategies;  Product  Trademarks.  Allogene  shall  have  the  right  and  responsibility  in
formulating  global  branding  strategies  for  the  Products.  Licensee  shall  reasonably  cooperate  with  Allogene  and  evaluate  and
consider in good faith changes in its branding strategy that would be necessary to implement such global branding strategy for the
Products in the Licensee Territory, and shall conduct commercialization activities in the Licensee Territory in accordance with
due consideration of such global branding strategy. Specifically, Licensee shall only use (pursuant to this Section 6.6), and shall
cause its Affiliates and Sublicensees to only use, the trademarks Controlled by Allogene in the Licensee Territory as Allogene
may  provide  to  Licensee  in  writing  from  time  to  time  (the  “Allogene  Product  Marks”).  Allogene  hereby  grants  to  Licensee,
during  the  Term  and  subject  to  the  terms  and  conditions  of  this  Agreement,  a  royalty-free,  exclusive  license  under  Allogene’s
rights to use such Allogene Product Marks in connection with the Commercialization of the Products in the Field in the Licensee
Territory  in  compliance  with  Applicable  Laws.  Licensee  may  also  adopt,  register  and  use  other  trademarks,  logos,  and  trade
names  in  local  language  in  the  applicable  jurisdiction  in  the  Licensee  Territory  to  co-brand  the  Product  (the  “Local  Product
Marks”);  provided,  however,  that  (a)  Licensee  will  endeavor  in  good  faith  to  ensure  that  such  Local  Product  Marks  shall  be
consistent with Allogene’s global branding strategy, (b) prior to first use, Licensee shall submit such trademarks, logos and trade
names for Allogene’s prior review and comment, (c) Licensee shall consider in good faith any comments received in a timely
manner from Allogene, and (d) Licensee may thereafter apply for registration of such Local Product Marks in its name and at its
cost in the Licensee Territory.

6.7

Ex-Licensee Territory and Ex-Field Activities. Licensee hereby covenants and agrees that during the Term it
shall not (and shall cause its Affiliates and Sublicensees and subcontractors not to), either itself or through a Third Party, develop,
use, market, promote,

-32-

import, export, sell or actively offer for sale the Products outside the Field in the Licensee Territory or in or outside the Field in
the Allogene Territory. Without limiting the generality of the foregoing, Licensee shall not (i) engage in any advertising activities
relating  to  the  Products  directed  primarily  to  customers  in  the  Allogene  Territory  (which  excludes  any  participation  in
conferences,  congresses  or  scientific  or  medical  meetings  held  throughout  the  world),  or  (ii)  actively  or  intentionally  solicit
orders from any prospective purchaser located in the Allogene Territory. To the extent permitted by Applicable Laws, including
applicable antitrust laws, if Licensee receives any order for Allogene’s product or Products from a prospective purchaser located
in a jurisdiction in the Allogene Territory, Licensee shall immediately refer that order to Allogene and shall not accept any such
order  or  deliver  or  tender  (or  cause  to  be  delivered  or  tendered)  the  Products  under  such  order.  If  Licensee  should  reasonably
know that a customer or distributor is actively engaged itself or through a Third Party in the sale or distribution of the Products in
the Allogene Territory or outside the Field within the Licensee Territory, then Licensee shall (A) within [***] Business Days of
gaining knowledge of such activities, notify Allogene regarding such activities and provide all information available to Licensee
that  Allogene  may  reasonably  request  concerning  such  activities  and  (B)  use  Commercially  Reasonable  Efforts  (including
cessation of sales to such customer) necessary to limit such sale or distribution outside the Licensee Territory or the Field, unless
otherwise agreed in writing by the Parties.

Third Party Payments. Licensee shall be responsible for all Known Third-Party Obligations existing as of the
Effective Date that are set forth in Schedule 1.74, and shall make such payments directly to the applicable Third Parties to satisfy
such  Known  Third-Party  Obligations.  With  respect  to  a  particular  jurisdiction  within  the  Licensee  Territory,  if  Developing,
Manufacturing,  using  or  Commercializing  any  Compound  or  Product  or  practicing  (or  sublicensing)  any  of  the  Allogene
Technology  would  be  impractical  or  impossible  without  obtaining  a  Third  Party  IP  License,  then  Licensee  will  be  entitled  to
deduct from royalty payments under Section 8.3 otherwise payable to Allogene in such jurisdiction by an amount equal to [***]
percent ([***]%) of the Third Party IP Costs allocable to such jurisdiction and actually paid by Licensee (or any of its Affiliates
or  Sublicensees)  to  a  Third  Party  under  a  Third  Party  IP  License,  provided,  no  payment  shall  be  reduced  by  more  than  [***]

General. In the event any withholding, value added, or other tax (including any tax based on income to
Allogene) (“Tax Withholdings”) is required to be withheld and deducted from payments by Licensee (or its Affiliate paying on
behalf of Licensee) pursuant to this Agreement under Applicable Laws, Licensee (or its Affiliate paying on behalf of Licensee)
will make such deduction and withholding and will pay the remainder to Allogene, and any amounts so withheld and deducted
will be remitted by Licensee (or its Affiliate paying on behalf of Licensee) on a timely basis to the appropriate Governmental
Authority  for  the  account  of  Allogene  and  Licensee  (or  its  Affiliate  paying  on  behalf  of  Licensee)  will  provide  Allogene
reasonable evidence of the remittance within [***] days thereof and for the purposes of this

-37-

Agreement, Licensee will be deemed to have fulfilled all of its payment obligations to Allogene with respect to such payments
paid to the such Governmental Authority. Licensee may satisfy its withholding, value added or other tax obligations under this
Section 8.8(a) through its Affiliates.

(b)

Taxes Resulting From Licensee Action. Notwithstanding Section 8.8(a), if, as a result of any action by
Licensee, including assignment, sublicense or transfer of this Agreement, change in the residence of Licensee for tax purposes,
change in the entity making such payment, or failure on the part of Licensee to comply with applicable Laws or filing or record
retention  requirements,  the  amount  of  any  tax  (including  income  tax,  value  added  tax,  interest,  or  penalties)  that  Licensee  is
required to deduct or withhold from a payment made by Licensee to Allogene under this Agreement is increased such that the
aggregate deduction or withholding is more than [***] percent ([***]%), then the sum payable by Licensee to Allogene shall be
increased to the extent necessary to ensure that Allogene receives a sum equal to the sum that Allogene would have received had
no such action occurred, less [***] percent ([***]%).

(c)

Tax Cooperation. Allogene  and  Licensee  shall  cooperate  with  respect  to  all  documentation  required  by
any  taxing  authority,  the  preparation  of  any  tax  returns,  or  reasonably  requested  by  either  Allogene  or  Licensee  to  secure  a
reduction  in  the  rate  of  applicable  taxes.  Each  of  Allogene  and  Licensee  shall  provide  the  other  Party  and  its  Affiliates  with
reasonable  assistance  to  enable  Allogene  and  Licensee  to  recovery,  as  permitted  by  applicable  Laws,  of  Tax  Withholdings
resulting  from  payments  made  under  this  Agreement,  such  recovery  to  be  for  the  benefit  of  the  Party  bearing  such  Tax
Withholdings. The Parties hereby agree to consult in good faith and use reasonable efforts to structure the Licensee’s exploitation
of the licenses granted hereunder and expansion in the Licensee Territory with the intent of minimizing taxes, charges or duties in
accordance with Applicable Law.

8.9

Blocked Currency. If by applicable Laws or fiscal policy of a jurisdiction in the Licensee Territory, conversion
into US Dollars or transfer of funds of a convertible currency to the United States is restricted, forbidden or substantially delayed,
then amounts accrued in such jurisdiction under this Agreement will be paid to Allogene in such jurisdiction in local currency by
deposit in a local bank designated by Allogene, unless Allogene and Licensee otherwise agree.’

8.10

Records; Audits.

(a)

Records. Licensee shall keep, and require its Affiliates and Sublicensees to keep, complete, fair and true
books of accounts and records for the purpose of determining the amounts payable to Allogene pursuant to this Agreement. Such

pertain.

(b)

Audits. During the term of this Agreement and for a period of [***] years thereafter, upon [***] days prior
notice  from  Allogene,  Licensee  will  permit,  and  will  cause  its  Affiliates  and  Sublicensees  to  permit,  an  independent  certified
public  accounting  firm  of  nationally  recognized  standing  selected  by  Allogene  and  reasonably  acceptable  to  Licensee,  to
examine, at Allogene’s sole expense, the relevant books and records of Licensee, its Affiliates

-38-

and  Sublicensees  for  the  sole  purpose  of  verifying  the  amounts  reported  by  Licensee  in  accordance  with  Section  8.3  and  the
payment of royalties and milestone payments hereunder. An audit by Allogene under this Section 8.10 will occur not more than
once in any Calendar Year, unless otherwise requested by the Upstream Licensors pursuant to the applicable Existing Allogene
In-Licenses, and will be limited to the pertinent books and records for any Calendar Year ending not more than [***] years before
the date of the request. The accounting firm will be provided access to such books and records at the facility(ies) of Licensee, its
Affiliates  or  Sublicensees,  as  applicable,  where  such  books  and  records  are  normally  kept  and  such  examination  will  be
conducted  during  normal  business  hours.  Licensee  or  the  applicable  Sublicensee  may  require  the  accounting  firm  to  sign  a
reasonably acceptable non-disclosure agreement before providing the accounting firm with access to facilities or records. Upon
completion  of  the  audit,  the  accounting  firm  will  provide  both  Allogene  and  Licensee  a  written  report  disclosing  any
discrepancies in the reports submitted by Licensee or the royalties or milestone payments paid by Licensee, and, in each case, the
specific  details  concerning  any  discrepancies.  Such  accounting  firm  shall  not  disclose  Licensee’s  Confidential  Information  to
Allogene,  except  to  the  extent  such  disclosure  is  necessary  to  verify  the  accuracy  of  the  reports  furnished  by  Licensee  in
accordance with Section 8.3 or the amount of payments by Licensee under this Agreement, in which case Allogene’s obligations
with respect to such Confidential Information shall be subject to Article 9.

(c)

Overpayments  and  Underpayments.  If  such  accounting  firm  concludes  that  additional  royalties  or
milestone  payments  were  due  to  Allogene  and  which  are  undisputed  by  Licensee,  then  Licensee  will  pay  to  Allogene  the
additional  royalties  or  milestone  payments  within  [***]  days  of  the  date  Licensee  receives  such  accountant’s  written  report.
Further, if the amount of such underpayments exceeds more than [***] percent ([***]%) of the amount that was properly payable
to  Allogene,  then  Licensee  will  reimburse  Allogene  for  Allogene’s  reasonable  documented  out-of-pocket  costs  incurred  to
conduct the audit. If such accounting firm concludes that Licensee overpaid royalties or milestone payments to Allogene, then
such overpayments will be credited against future amounts payable by Licensee to Allogene, or, if no further payments are to be
made to Allogene under this Agreement, Allogene shall promptly repay such overpayment.

(d)

Confidentiality. Notwithstanding any provision of this Agreement to the contrary all reports and financial
information  of  Licensee  or  its  Affiliates’  or  Sublicensees  which  are  provided  to  or  subject  to  inspection,  audit,  or  review  by
Allogene  under  this  Section  8.10  or  elsewhere  in  this  Agreement  (including  without  limitation,  all  Development  reports,
Commercialization  reports,  royalty  reports,  and  other  books  and  records)  will  be  deemed  to  be  Licensee’s  Confidential
Information and subject to the provisions of Article 9.

8.11

Late Payments. Any payments not made by Licensee on or before the date such payments become due under this
Agreement shall bear interest at a floating rate equal to the prime interest rate quoted by The Wall Street Journal, Internet U.S.
Edition at www.wsj.com on the date when the payment was due plus [***] percent ([***]%) or the highest rate permitted by law
(whichever is lower), computed from the date such payment was due until the date Licensee makes the payment. If such prime
interest rate is no longer quoted, the Parties shall agree on a

-39-

reasonable substitute therefor. The payment of such interest shall not limit Allogene from exercising any other rights it may have
as a consequence of the lateness of any payment.

9.1

Confidential Information

Article 9
Confidentiality

. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the Parties, each Party (in such
capacity, the “Receiving Party”) agrees that, during the Term and for [***] years thereafter, it shall keep confidential and shall
not publish or otherwise disclose to any Third Party, and shall not use for any purpose other than as expressly provided for in this
Agreement or any other written agreement between the Parties, including the Supply and Quality Agreements, any Confidential
Information furnished or made available to it by or on behalf of the other Party (in such capacity, the “Disclosing Party”).  The
Receiving Party shall use at least the same standard of care as it uses to protect proprietary or confidential information of its own
(but  in  no  event  less  than  reasonable  care)  to  ensure  that  its,  and  its  Affiliates’,  employees,  agents,  consultants  and  other
representatives  do  not  disclose  or  make  any  unauthorized  use  of  the  Confidential  Information.  The  Receiving  Party  shall
promptly notify the Disclosing Party upon discovery of any unauthorized use or disclosure of the Disclosing Party’s Confidential
Information.

9.2

Exceptions. Confidential Information shall not include any information which the Receiving Party can prove by
competent evidence: (a) is now, or hereafter becomes, through no act or failure to act on the part of the Receiving Party, generally
known or available to the public; (b) is rightfully known by the Receiving Party and/or any of its Affiliates (and/or in the case of
Licensee, its Sublicensees) at the time of receiving such information, as evidenced by its records; (c) is hereafter furnished to the
Receiving Party and/or any of its Affiliates by a Third Party, as a matter of right and without restriction; or (d) is independently
discovered  or  developed  by  the  Receiving  Party  and/or  any  of  its  Affiliates  (and/or  in  the  case  of  Licensee,  its  Sublicensees),
without the use of or reference to Confidential Information of the Disclosing Party.

9.3

Authorized  Disclosure.  Notwithstanding  the  provisions  of  Section  9.1,  the  Receiving  Party  may  disclose
Confidential Information of the Disclosing Party as expressly permitted by this Agreement, or if and to the extent such disclosure
is reasonably necessary in the following instances:

(a)

as  reasonably  necessary  to  obtain  and  maintain  Regulatory  Approval  or  to  otherwise  Develop,

Manufacture, use or Commercialize Products in accordance with this Agreement;

(b)

disclosure to Affiliates, actual and potential licensees and Sublicensees, employees, consultants, advisors
or agents of the Receiving Party who have a need to know such information in order for the Receiving Party to exercise its rights
or fulfill its obligations under

-40-

this Agreement, provided, in each case, that any such Affiliate, actual or potential licensee or Sublicensee, employee, consultant
or agent agrees to be bound by obligations of confidentiality and non-use (or are bound by professional obligations of privilege)
that are no less stringent than the confidentiality and non-use obligations contained hereof;

(c)

in  the  case  of  Allogene,  disclosure  to  the  extent  required  to  comply  with  the  Existing  Allogene  In-

Licenses; and

(d)

disclosure to bona-fide potential or actual Third Party investors, collaborators or acquirers in confidential
financing  documents,  provided,  in  each  case,  that  any  such  Third  Party  agrees  to  be  bound  by  reasonable  and  customary
obligations of confidentiality and non-use.

Notwithstanding  the  foregoing,  in  the  event  a  Party  is  required  to  make  a  disclosure  of  the  other  Party’s  Confidential
Information pursuant to Section 9.3(c) or Section 9.3(d), it will, except where impracticable, give reasonable advance notice to
the other Party of such disclosure and use efforts to secure confidential treatment of such information at least as diligent as such
Party  would  use  to  protect  its  own  confidential  information,  but  in  no  event  less  than  commercially  reasonable  efforts.  In  any
event, the Parties agree to take all reasonable action to avoid disclosure of Confidential Information hereunder.

It shall not be considered a breach of this Agreement if the Receiving Party discloses Confidential Information in order to
comply  with  a  lawfully  issued  court  or  governmental  order  or  with  a  requirement  of  Applicable  Laws  or  the  rules  of  any
internationally recognized stock exchange; provided that: (i) the Receiving Party gives prompt written notice of such disclosure
requirement  to  the  Disclosing  Party  and  cooperates  with  the  Disclosing  Party’s  efforts  to  oppose  such  disclosure  or  obtain  a
protective order for such Confidential Information, and (ii) if such disclosure requirement is not quashed or a protective order is
not obtained, the Receiving Party shall only disclose those portions of the Confidential Information that it is legally required to
disclose  and  shall  make  a  reasonable  effort  to  obtain  confidential  treatment  for  the  disclosed  Confidential  Information.  To  the
extent  there  is  any  conflict  between  this  Article  9  and  any  other  agreement  related  to  Confidential  Information  entered  into
between the Parties, this Agreement shall control.

9.4

Public Announcements.

(a)

Press  Releases.  As  soon  as  practicable  following  the  Effective  Date,  Allogene  and  Overland
Pharmaceuticals (US) Inc. shall issue a joint press release announcing the execution of this Agreement in a form mutually agreed
by  the  Parties.  Except  as  required  by  applicable  securities  laws  (including  disclosure  requirements  of  the  U.S.  Securities  and
Exchange Commission (“SEC”) or any stock exchange on which securities issued by a Party or its Affiliates are traded), neither
Party shall make any other public announcement concerning this Agreement or the subject matter hereof without the prior written
consent  of  the  other,  which  shall  not  be  unreasonably  withheld  or  delayed;  provided  that  each  Party  may  make  any  public
statement in response to questions by the press, analysts, investors or those attending industry conferences or financial analyst
calls, or issue press releases, so long as any such public

-41-

statement  or  press  release  is  not  inconsistent  with  prior  public  disclosures  or  public  statements  approved  by  the  other  Party
pursuant to this Section 9.4 and which do not reveal nonpublic information about the other Party. In the event of a required public
announcement, to the extent practicable under the circumstances, the Party making such announcement shall provide the other
Party with a copy of the proposed text of such announcement sufficiently in advance of the scheduled release to afford such other
Party a reasonable opportunity to review and comment upon the proposed text.

(b)

Filing of this Agreement. The Parties shall coordinate in advance with each other in connection with the
filing of this Agreement (including redaction of certain provisions of this Agreement) with the SEC or any stock exchange or
governmental agency on which securities issued by a Party or its Affiliate are traded, and each Party will use reasonable efforts to
seek  confidential  treatment  for  the  terms  proposed  to  be  redacted;  provided  that  each  Party  will  ultimately  retain  control  over
what information to disclose to the SEC or any stock exchange or other governmental agency, as the case may be, and provided
further that the Parties will use their reasonable efforts to file redacted versions with any governing bodies which are consistent
with redacted versions (if any) previously filed with any other governing bodies. Other than such obligation, neither Party (nor its
Affiliates) will be obligated to consult with or obtain approval from the other Party with respect to any filings to the SEC or any
stock exchange or other governmental agency.

9.5

Publication. At  least  [***]  days  prior  to  publishing,  publicly  presenting,  and/or  submitting  for  written  or  oral
publication a manuscript, abstract or the like that includes Information relating to any of the Products that has not been previously
published, Licensee shall provide to Allogene a draft copy thereof for its review (unless Licensee is required by law to publish
such  Information  sooner,  in  which  case  Licensee  shall  provide  such  draft  copy  to  the  Allogene  as  much  in  advance  of  such
publication  as  possible).  Licensee  shall  consider  in  good  faith  any  comments  provided  by  Allogene  within  [***]  days  of
receiving the draft. In addition, Licensee shall, at Allogene’s reasonable request, remove therefrom any Confidential Information
of Allogene. Allogene  shall  also  have  the  right  to  delay  any  presentation  or  publication  for  [***]  days  to  enable  the  filing  of
patent applications protecting any Product. The contribution of each Party shall be noted in all publications or presentations by
acknowledgment  or  co-authorship,  whichever  is  appropriate.  At  least  [***]  days  prior  to  publishing  or  publicly  presenting
Information relating to any of the Products that has not been previously published or publicly presented, Allogene shall provide
to Licensee a draft copy thereof (unless Allogene is required by law to publish such Information sooner, in which case Allogene
shall provide such draft copy to the Licensee as much in advance of such publication or presentation as practicable or, if prior
notice is not practicable, promptly following such publication or presentation).

9.6

Prior Non-Disclosure Agreement. As of the Effective Date, the terms of this Article 9 shall supersede any prior
non-disclosure,  secrecy  or  confidentiality  agreement  between  the  Parties  (or  their  Affiliates)  dealing  with  the  subject  of  this
Agreement, including the Confidentiality Agreement. Any information disclosed pursuant to any such prior agreement shall be
deemed Confidential Information for purposes of this Agreement.

-42-

9.7

Equitable Relief. Given the nature of the Confidential Information and the competitive damage that would result
to a Party upon unauthorized disclosure, use or transfer of its Confidential Information to any Third Party, the Parties agree that
monetary damages would not be a sufficient remedy for any breach of this Article 9. In addition to all other remedies, a Party
shall be entitled to seek specific performance and injunctive and other equitable relief as a remedy for any breach or threatened
breach of this Article 9.

Party  of  all  inter  partes  reviews,  invalidity  actions,  conflict  proceedings,  reexaminations,  reissuance,  oppositions,  revocation
proceedings  or  any  other  material  challenge  relating  to  a  given  Joint  Invention  Patent  in  the  Prosecuting  Party’s  territory.  The
Prosecuting Party will consult with, and consider in good faith the requests and suggestions of, the other Party with respect to
strategies  for  filing  and  prosecuting  the  Joint  Invention  Patents  in  the  Prosecuting  Party’s  territory.  In  the  event  that  the

any Platform Inventions) or any Joint Invention Patent at its own expense and by counsel of its own choice. Allogene shall keep
Licensee reasonably informed of the litigation and reasonably consider Licensee's requests, suggestions, and business interests in
connection with such litigation. If Allogene decides not to bring any such action or proceeding with respect to infringement of
any  Allogene  Protected  Patent  (or  any  Joint  Invention  Patent)  within  [***]  days  following  the  written  notice  of  alleged
infringement, Licensee shall have the right to bring and control any such action at its own expense and by counsel of its own
choicebut only to the extent such infringement is in the Field and the Licensee Territory, and Allogene shall have the right, at its

without the prior written consent of such other Party, which shall not be unreasonably withheld. Except as otherwise agreed by
the Parties in connection with a cost-sharing arrangement, any recovery realized by a Party as a result of any action or proceeding
pursuant  to  this  Section  11.3,  whether  by  way  of  settlement  or  otherwise,  shall  be  applied  first  to  reimburse  the  Parties’

Party to the other Party under this Article 11 is protected by attorney-client privilege or any other applicable legal privilege or
immunity,  such  Party  shall  not  be  required  to  disclose  such  Information  and  the  Parties  shall  in  good  faith  cooperate  to  agree
upon a procedure (which may include entering into a specific common interest agreement, disclosing such Information on a “for

Rights Upon Bankruptcy.  All  rights  and  licenses  granted  under  or  pursuant  to  this  Agreement  are,  and  shall
otherwise be deemed to be, for purposes of Section 365(n) of Title 11 of the United States Code and other similar laws in any
jurisdiction  outside  the  U.S.  (collectively,  the  “Bankruptcy  Laws”),  licenses  of  rights  to  be  “intellectual  property”  as  defined
under  the  Bankruptcy  Laws.  If  a  case  is  commenced  during  the  Term  by  or  against  a  Party  under  the  Bankruptcy  Laws  then,
unless and until this Agreement is rejected as provided in such Bankruptcy Laws, such Party (in any capacity, including debtor-
in-possession) and its successors and assigns (including a trustee) shall perform all of the obligations provided in this Agreement
to be performed by such Party. If a case is commenced during the Term by or against a Party under the Bankruptcy Laws, this
Agreement is rejected as provided in the Bankruptcy Laws and the

-56-

other Party elects to retain its rights hereunder as provided in the Bankruptcy Laws, then the Party subject to such case under the
Bankruptcy Laws (in any capacity, including debtor-in-possession) and its successors and assigns (including a Title 11 trustee),
shall provide to the other Party copies of all Information necessary for such other Party to prosecute, maintain and enjoy its rights
under the terms of this Agreement promptly upon such other Party’s written request therefor. All rights, powers and remedies of
the  non-bankrupt  Party  as  provided  herein  are  in  addition  to  and  not  in  substitution  for  any  and  all  other  rights,  powers  and
remedies now or hereafter existing at law or in equity (including, without limitation, the Bankruptcy Laws) in the event of the
commencement of a case by or against a Party under the Bankruptcy Laws.

12.7

Option  to  Continue  In-Lieu  of  Termination  for  Serious  Material  Breach.    If  Licensee  has  the  right  to
terminate this Agreement under Section 12.2(a) as a result of any Serious Material Breach that has not been cured in accordance
with  Section  12.2(a),  it  may  elect  (at  its  sole  discretion)  not  to  exercise  such  termination  right  and  instead  to  exercise  the
alternative  remedy  set  forth  in  this  Section  12.7  by  providing  written  notice  of  such  election  to  Allogene  within  [***]  days
following the end of the cure period specified in Section 12.2(a). If Licensee provides such written notice, this Agreement shall
continue in full force and effect, except as follows:

(a)

Payments. Without limiting Licensee's other remedies hereunder, any milestone or royalty payment under
Article 8 that becomes due thereafter shall be reduced by [***] percent ([***]%) after applying all other applicable deductions
and reductions to such payments permitted under this Agreement;

(b)

Certain  Rights  and  Obligations.  Licensee's  diligence  obligations  under  Article  3  (Development)  and
Article  6  (Commercialization)  (Diligence),  and  its  obligation  to  provide  reports,  updates  and  other  information  under  those
Articles, shall cease immediately; and

(c)

Reasonable Remedies. The Parties acknowledge and agree that the remedies set forth in this Section 12.7
are reasonable remedies, in lieu of Licensee's exercise of its termination right, for the occurrence of any of the circumstances for
which Licensee has the right to terminate this Agreement under Section 12.2(a).

Article 13

13.1

Indemnification  of  Allogene.  Licensee  shall  indemnify  and  hold  harmless  each  of  Allogene,  each  Upstream
Licensor,  their  respective  Affiliates,  and  their  respective  directors,  officers,  employees,  consultants,  agents  and  successors  and
assigns of any of the foregoing (the “Allogene Indemnitees”) from and against any and all losses, damages, liabilities, expenses
and costs, including reasonable legal expense and attorneys’ fees that are payable to an un-Affiliated Third Party (“Losses”), and
which are incurred by any Allogene Indemnitee as a result of any claims, demands, actions, suits or proceedings brought by a
Third  Party  (“Third  Party  Claims”)  arising  directly  or  indirectly  out  of:  (a)  the  practice  by  Licensee  or  its  Affiliates  or
Sublicensees of

-57-

the license grant pursuant to Section 2.1; (b) the research, Development, Manufacture, testing, importation, Commercialization,
use,  handling,  storage,  sale,  offer  for  sale  or  other  disposition  or  exploitation  of  the  Compound,  Subject  Antibodies,  Subject
Antibody  Materials,  or  the  Products  by  Licensee  or  its  Affiliates,  Sublicensees  or  permitted  subcontractors  (including  product
liability  and  intellectual  property  infringement  claims);  (c)  the  negligence  or  willful  misconduct  of  any  Licensee  Indemnitee;
(d) any breach of any of the terms of this Agreement, including the representations, warranties or covenants by Licensee under
this Agreement; (e) Allogene holding any Regulatory Approval for any Product for Licensee’s benefit in accordance with Section
4.1,  or  (f)  violation  of  Applicable  Law  by  Licensee  or  any  of  its  Affiliates  or  permitted  subcontractors  or  Sublicensees  in  the
exercise of the license grant set forth in Section 2.1 or otherwise in connection with this Agreement; except, (g) in each case, to
the extent such that such Third Party Claim alleges any infringement, misappropriation, or other violation of the Third Party's
rights in Patents, Know-How, or other intellectual or proprietary rights, or that such Third Party Claims fall within the scope of
the indemnification obligations of Allogene set forth in Section 13.2 or as set forth in any of the Supply and Quality Agreements.

13.2

Indemnification of Licensee. Allogene shall indemnify and hold harmless each of Licensee and its Affiliates and
Sublicensees,  and  their  respective  directors,  officers,  employees,  consultants,  agents  and  successors  and  assigns  of  any  of  the
foregoing (the “Licensee Indemnitees”), from and against any and all Losses incurred by any Licensee Indemnitee as a result of
any Third Party Claims arising directly or indirectly out of: (a) the practice by Allogene or its Affiliates of the license granted to
Allogene  under  Section  2.6;  (b)  the  development,  manufacture,  use,  handling,  storage,  sale  or  other  disposition  of  the
Compounds, 647 Compounds, 647 Products or Products by Allogene or its Affiliates; (c) the negligence or willful misconduct of
any Allogene Indemnitee; or (d) any breach of any representations, warranties or covenants by Allogene under this Agreement;
except, in each case, to the extent such Third Party Claims fall within the scope of the indemnification obligations of Licensee set
forth in Section 13.1.

13.3

Procedure. As conditions to the Indemnitees’ right to receive indemnification under this Article 13, a Allogene
Indemnitee  or  Licensee  Indemnitee  that  intends  to  claim  indemnification  under  this  Article  13  (the  “Indemnitee”)  shall  (a)
promptly  notify  the  indemnifying  Party  (the  “Indemnitor”)  in  writing  of  any  Third  Party  Claim,  in  respect  of  which  the
Indemnitee intends to claim such indemnification (provided that failure to notify the Indemnitor shall not relieve the Indemnitor
of  its  obligation  to  indemnify  hereunder  unless  such  failure  materially  prejudices  such  Indemnitor’s  rights),  (b)  reasonably
cooperate,  and  cause  the  applicable  individual  Indemnitees  to  cooperate,  with  Indemnitor  in  the  defense,  settlement  or
compromise  of  such  Third  Party  Claim,  and  (c)permit  the  Indemnitor  to  have  sole  control  of  the  defense,  settlement  or
compromise of such Third Party Claim, including the right to select defense counsel. In no event, however, may the Indemnitor
compromise or settle any Third Party Claim in a manner which admits fault or negligence on the part of Indemnitee without the
prior written consent of the Indemnitee. The Indemnitee shall not have any liability under this Article 13 with respect to Third
Party Claims settled or compromised without its prior written consent, such consent not to be unreasonably withheld, conditioned
or delayed.

13.4

Insurance. Each Party shall maintain during the Term and for a period of [***] years thereafter, product liability
and clinical trial insurance, when applicable, which are generally consistent with normal business practices of prudent companies
similarly  situated  as  determined  in  good  faith  by  such  Party;  provided,  however,  that  in  no  event  shall  such  product  liability
insurance be written and in force in amounts less than [***] per claim, or such greater amount as such Party customarily obtains
in  connection  with  its  product  candidates  that  are  not  Products.  Upon  request,  each  Party  shall  provide  the  other  Party  with  a
certificate of insurance evidencing the coverage required under this Section 13.4. Each Party shall provide the other Party with
written notice of cancellation, non-renewal or material change in such insurance, and shall provide such notice within [***] days
after  any  such  cancellation,  nonrenewal  or  material  change.  Licensee  shall  impose  substantially  similar  obligations  on  its
Affiliates (to the extent not named insureds under Licensee’s coverages) and Sublicensees. If Licensee or Allogene becomes, or
Licensee’s Sublicensee is, a global pharmaceutical company that is self-insured generally and consistently across its business and
product  portfolio  against  liability  and  other  risks  associated  with  its  activities  and  obligations  under  this  Agreement  in  such
amounts and on such terms as are customary for prudent practices for global pharmaceutical companies, Licensee, Allogene, or
such Sublicensee may substitute, upon written notice to Allogene or Licensee, as applicable,, such program of self-insurance for
the insurance policies otherwise required under this Section 13.4. It is understood and agreed that the insurance or self-insurance
provided under this Section 13.4 shall not be construed to limit either Party's liability with respect to its indemnification or other
obligations hereunder.

13.5

Limitation  of  Liability.  NEITHER  PARTY  SHALL  BE  LIABLE  TO  THE  OTHER  FOR  ANY  SPECIAL,
CONSEQUENTIAL,  INCIDENTAL,  PUNITIVE,  OR  INDIRECT  DAMAGES  ARISING  FROM  OR  RELATING  TO  ANY
BREACH  OF  THIS  AGREEMENT,  REGARDLESS  OF  ANY  NOTICE  OF  THE  POSSIBILITY  OF  SUCH  DAMAGES.
NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 13.5 IS INTENDED TO OR SHALL LIMIT OR
RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTION 13.1 OR 13.2, OR
DAMAGES AVAILABLE FOR A PARTY’S BREACH OF ITS CONFIDENTIALITY OBLIGATIONS IN SECTION 9.

Article 14
Dispute Resolution

14.1

Disputes. Subject to Section 14.3, upon the written request of either Party to the other Party, any claim, dispute,
or controversy as to the breach, enforcement, interpretation or validity of this Agreement (a “Dispute”)  will be referred to  the
Executive Officers for attempted resolution. In the event such executives are unable to resolve such Dispute within [***] days
after  the  initial  written  request,  then,  upon  the  written  demand  of  either  Party,  the  Dispute  shall  be  subject  to  arbitration,  as
provided in Section 14.2, except as expressly set forth in Section 14.3.

14.2

Arbitration.

-59-

(a)

Claims. Subject to Section 14.3 below, any Dispute that is not resolved under Section 14.1 within [***]
days after a Party’s initial written request for resolution, shall be resolved by final and binding arbitration before a panel of three
neutral experts with relevant industry experience. The arbitration proceeding shall be administered by the International Court of
Arbitration  of  the  International  Chamber  of  Commerce  (the  “ICC”)  in  accordance  with  its  then  existing  arbitration  rules  or
procedures  regarding  commercial  or  business  disputes,  and  the  panel  of  arbitrators  shall  be  selected  in  accordance  with  such
rules.  The  arbitration  and  all  associated  discovery  proceedings  and  communications  shall  be  conducted  in  English,  and  the
arbitration shall be held in New York. Except to the extent necessary to confirm an award or as may be required by law, neither a
Party  nor  an  arbitrator  may  disclose  the  existence,  content,  or  results  of  arbitration  without  the  prior  written  consent  of  both
Parties.

(b)

Arbitrators’  Award.  The  arbitrators  shall,  within  [***]  days  after  the  conclusion  of  the  arbitration
hearing, issue a written award and statement of decision describing the essential findings and conclusions on which the award is
based, including the calculation of any damages awarded. The decision or award rendered by the arbitrators shall be final and
non-appealable, and judgment may be entered upon it in any court of competent jurisdiction. Either Party may apply for interim
injunctive  relief  with  the  arbitrators  until  the  arbitration  award  is  rendered  or  the  controversy  is  otherwise  resolved.  The
arbitrators shall be authorized to award compensatory damages, but shall not be authorized (i) to award non-economic damages,
(ii)  to  award  punitive  damages  or  any  other  damages  expressly  excluded  under  this  Agreement,  or  (iii)  to  reform,  modify  or
materially  change  this  Agreement  or  any  other  agreements  contemplated  hereunder;  provided,  however,  that  the  damage
limitations described in subsections (i) and (ii) of this sentence will not apply if such damages are statutorily imposed.

(c)

Costs. Each Party shall bear its own attorney’s fees, costs, and disbursements arising out of the arbitration,
and shall pay an equal share of the fees and costs of the arbitrator; provided, however, that the arbitrator shall be authorized to
determine whether a Party is the prevailing party, and if so, to award to that prevailing party reimbursement for any or all of its
reasonable  attorneys’  fees,  costs  and  disbursements  (including,  for  example,  expert  witness  fees  and  expenses,  photocopy
charges, travel expenses, etc.), and/or the fees and costs of the ICC and the arbitrator.

14.3

Court Actions. Nothing contained in this Agreement shall deny either Party the right to seek, upon good cause,
injunctive  or  other  equitable  relief  from  a  court  of  competent  jurisdiction  in  the  context  of  an  emergency  or  prospective
irreparable harm, and such an action may be filed and maintained notwithstanding any ongoing dispute resolution discussions or
arbitration proceedings. In addition, either Party may bring an action in any court of competent jurisdiction to resolve disputes
pertaining  to  the  validity,  construction,  scope,  enforceability,  infringement  or  other  violations  of  Patents  or  other  intellectual
property rights, and no such claim shall be subject to arbitration pursuant to Section 14.2.

15.3

Relationship Between the Parties. The Parties’ relationship, as established by this Agreement, is solely that of
independent contractors. This Agreement does not create any partnership, joint venture or similar business relationship between
the  Parties.  Neither  Party  is  a  legal  representative  of  the  other  Party,  and  neither  Party  can  assume  or  create  any  obligation,
representation, warranty or guarantee, express or implied, on behalf of the other Party for any purpose whatsoever.

15.4

Non-Waiver. The failure of a Party to insist upon strict performance of any provision of this Agreement or to
exercise  any  right  arising  out  of  this  Agreement  shall  neither  impair  that  provision  or  right  nor  constitute  a  waiver  of  that
provision or right, in whole or in part, in that instance or in any other instance. Any waiver by a Party of a particular provision or
right shall be in writing, shall be as to a particular matter and, if applicable, for a particular period of time and shall be signed by
such Party.

15.5

Assignment.  Except  as  expressly  provided  hereunder,  neither  this  Agreement  nor  any  rights  or  obligations

15.7

Severability. If, for any reason, any part of this Agreement is adjudicated invalid, unenforceable or illegal by a
court  of  competent  jurisdiction,  such  adjudication  shall  not  affect  or  impair,  in  whole  or  in  part,  the  validity,  enforceability  or
legality of any remaining portions of this Agreement. All remaining portions shall remain in full force and effect as if the original
Agreement  had  been  executed  without  the  invalidated,  unenforceable  or  illegal  part.  The  Parties  shall  use  their  commercially

other information of a non-public nature received from any other Party or its Representatives, or prepared by such

Information  (A)  to  the  extent  legally  compelled  (including  without  limitation,  pursuant  to  any  applicable  tax,
securities, or other Laws of any jurisdiction); provided that such Party shall, where practicable and to the extent

required by applicable Laws or Governmental Order (including the rules and regulations of the New York Stock
Exchange  and  the  U.S.  Securities  and  Exchange  Commission).  Following  the  execution  of  this  Agreement,  the
Purchasers will issue a press release, the form and timing of which shall be agreed between the Purchasers.

MISCELLANEOUS

7.1
Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of
New York, U.S., without giving effect to any choice of law principles that would require the application of the laws of a
different  jurisdiction.  The  application  of  the  U.N.  Convention  on  Contracts  for  the  International  Sale  of  Goods  is
excluded.

7.2

Binding Arbitration.

(i)
All  disputes  under  this  Agreement  shall  be  submitted  by  either  Party  for  resolution  in  arbitration
administered  by  the  International  Chamber  of  Commerce  (the  “ICC”)  pursuant  to  its  arbitration  rules  and
procedures then in effect.

7    

The arbitration shall be conducted by a panel of three (3) arbitrators: within thirty (30) days after initiation
(ii)
of arbitration, each Party shall select one (1) person to act as arbitrator and the two Party-selected arbitrators shall
select  a  third  arbitrator  (who  shall  be  the  chairperson  of  the  arbitration  panel)  within  thirty  (30)  days  of  their
appointment. If the arbitrators selected by the Parties are unable or fail to agree upon the third arbitrator, the third
arbitrator  shall  be  appointed  by  ICC.  If,  however,  the  aggregate  award  sought  by  the  Parties  is  less  than
US$5,000,000 and equitable relief is not sought, the arbitration shall be conducted by a single arbitrator agreed by
the Parties (or appointed by ICC if the Parties cannot agree). The seat of arbitration shall be New York City, New
York and the language of the proceedings shall be English.

(iii)
The Parties agree that any award or decision made by the arbitral tribunal shall be final and binding upon
them and may be enforced in the same manner as a judgment or order of a court of competent jurisdiction. The
arbitral tribunal shall determine the dispute by applying the provisions of this Agreement and the governing law
set forth in Section 7.1.

(iv)
By agreeing to arbitration, the Parties do not intend to deprive any court of its jurisdiction to issue, at the
request  of  a  Party,  a  pre-arbitral  injunction,  pre-arbitral  attachment  or  other  order  to  avoid  irreparable  harm,
maintain  the  status  quo,  preserve  the  subject  matter  of  the  dispute,  or  aid  the  arbitration  proceedings  and  the
enforcement of any award. Without prejudice to such provisional or interim remedies in aid of arbitration as may
be  available  under  the  jurisdiction  of  a  competent  court,  the  arbitral  tribunal  shall  have  full  authority  to  grant
provisional  or  interim  remedies  and  to  award  damages  for  the  failure  of  any  party  to  the  dispute  to  respect  the
arbitral tribunal’s order to that effect.

EACH PARTY HERETO WAIVES ITS RIGHT TO TRIAL BY JURY OF ANY ISSUE RELATING TO

(v)
ANY DISPUTE ARISING HEREUNDER.

(vi)
Each Party shall bear its own attorney’s fees, costs, and disbursements arising out of the arbitration, and
shall  pay  an  equal  share  of  the  fees  and  costs  of  the  administrator  and  the  arbitrator;  provided,  however,  the
arbitrator  shall  be  authorized  to  determine  whether  a  Party  is  the  prevailing  party,  and  if  so,  to  award  to  that
prevailing party reimbursement for any or all of its reasonable attorneys’ fees, costs and disbursements (including,
for example, expert witness fees and expenses, photocopy charges, travel expenses, etc.), or the fees and costs of
the administrator and the arbitrator.

(b)  is  not  a  “U.S.  person”  and  is  located  outside  of  the  “United  States”,  as  such  terms  are  defined  in  Rule  902  of
Regulation S under the Act.

governing appropriate workplace behavior, (ii) anti-corruption and anti-money-laundering policies prohibiting actions by

provided  further  that  a  quorum  shall  be  deemed  present  at  the  third  time  if  the  meeting  has  been  so  adjourned  three  times.  A
quorum shall be constituted (whether in person or by means of a conference telephone or any other equipment which allows all
participants  in  the  meeting  to  speak  to  and  hear  each  other  simultaneously)  with  (a)  the  presence  of  at  least  one  (1)  Overland
Designee for so long as Overland is entitled to appoint a designate to the Board and (b) the presence of at least one (1) Allogene

issued or issuable upon the conversion of the Preferred Shares issued to Allogene at the Closing and (b) so long as Overland or its

5.

Registration Rights.

5.1

Applicability of Rights; Non-U.S. Registrations. The Holders shall be entitled to the following rights set forth in
the  provisions  of  this  Section 5  with  respect  to  any  potential  public  offering  of  the  Company’s  Ordinary  Shares  in  the  United
States  and  shall  be  entitled  to  reasonably  analogous  or  equivalent  rights  with  respect  to  any  other  offering  of  the  Company’s
securities in any other jurisdiction pursuant to which the Company undertakes to publicly offer or list such securities for trading
on a recognized securities exchange. For the purposes of this Section 5, reference to registration of securities under the Securities
Act and the Exchange Act shall be deemed to mean the equivalent registration in a jurisdiction other than the United States as
designated  by  such  Holders,  it  being  understood  and  agreed  that  in  each  such  case  all  references  in  this  Agreement  to  the
Securities Act, the Exchange Act and rules, forms of registration statements and registration of securities thereunder, U.S. law
and the SEC, shall be deemed to refer, to the equivalent statutes, rules, forms of registration statements, registration of securities
and laws of and equivalent government authority in the applicable non-U.S. jurisdiction.

5.2

Request for Registration.

(i)

Subject to the conditions of this Section 5.2, if the Company shall receive at any time after six (6) months
following the effective date of the registration statement for the IPO, a written request from the Holders of twenty-five percent
(25%) or more of the Registrable Securities then outstanding (for purposes of this Section 5.2, the “Initiating Holders”) that the
Company  file  a  registration  statement  under  the  Securities  Act  covering  the  registration  of  at  least  ten  percent  (10%)  of  the
Registrable  Securities  then  outstanding,  then  the  Company  shall,  within  twenty  (20)  days  of  the  receipt  thereof,  give  written
notice of such request to all Holders, and subject to the limitations of this Section 5.2,  use  commercially  reasonable  efforts  to
effect, as soon as practicable, the registration under the Securities Act of all Registrable Securities that the Holders request to be
registered in a written request received by the Company within twenty (20) days of the mailing of the Company’s notice pursuant
to this Section 5.2(i).

(ii)

If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of
an underwriting, they shall so advise the Company as a part of their request made pursuant to this Section 5.2, and the Company
shall include such information in the written notice referred to in Section 5.2(i). In such event the right of any

11

Holder  to  include  its  Registrable  Securities  in  such  registration  shall  be  conditioned  upon  such  Holder’s  participation  in  such
underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting (unless otherwise mutually agreed by a
majority in interest of the Initiating Holders and such Holder) to the extent provided herein. All Holders proposing to distribute
their securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or
underwriters  selected  for  such  underwriting  by  the  Company.  Notwithstanding  any  other  provision  of  this  Section  5.2,  if  the
underwriter advises the Company that marketing factors require a limitation on the number of securities underwritten (including
Registrable  Securities),  then  the  Company  shall  so  advise  all  Holders  of  Registrable  Securities  that  would  otherwise  be
underwritten pursuant hereto, and the number of Shares that may be included in the underwriting shall be allocated to the Holders
of  such  Registrable  Securities  pro  rata  based  on  the  number  of  Registrable  Securities  held  by  all  such  Holders  (including  the
Initiating Holders). In no event shall any Registrable Securities be excluded from such underwriting unless all other securities are
first  excluded.  Any  Registrable  Securities  excluded  or  withdrawn  from  such  underwriting  shall  be  withdrawn  from  the
registration.

(iii)

Notwithstanding the foregoing, the Company shall not be required to effect a registration pursuant to this

Section 5.2:

after  the  Company  has  effected  two  (2)  registrations  pursuant  to  this  Section 5.2,  and  such  registrations

(a)
have been declared or ordered effective;

If  the  Company  has  effected  a  registration  pursuant  to  this  Section 5.2  within  the  preceding  twelve  (12)

(b)
months, and such registration has been declared or ordered effective;

(c)
during the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the
date  of  the  filing  of,  and  ending  on  a  date  one  hundred  eighty  (180)  days  following  the  effective  date  of,  a
Company-initiated registration subject to Section 5.3, provided that the Company is actively employing in good
faith all commercially reasonable efforts to cause such registration statement to become effective;

if the Initiating Holders propose to dispose of Registrable Securities that may be registered on Form F-3

(d)
pursuant to Section 5.4;

(e)
if the Company shall furnish to Holders requesting a registration pursuant to this Section 5.2 a certificate
signed by the CEO or chair of the Board stating that in the good faith judgment of the Board, it would be seriously
detrimental to the Company and its members for such registration statement to be effected at such time, in which
event the Company shall have the right to defer such filing for a period of not more than ninety (90) days after
receipt of the request of the Initiating Holders, provided that the Company shall not register any other of its Shares
during such ninety (90) days period; or

in  any  particular  jurisdiction  in  which  the  Company  would  be  required  to  execute  a  general  consent  to

(f)
service of process in effecting such

12

registration, unless the Company is already subject to service in such jurisdiction and except as may be required
under the Securities Act or pursuant to applicable securities laws in other jurisdictions, as the case may be.

5.3

Company Registration.

(i)

If  (but  without  any  obligation  to  do  so)  the  Company  proposes  to  register  (including  for  this  purpose  a
registration  effected  by  the  Company  for  members  other  than  the  Holders)  any  of  its  Shares  or  other  securities  under  the
Securities Act in connection with the public offering of such securities (other than (i) a registration relating to a demand pursuant
to Section 5.2 or (ii) a registration relating solely to the sale of securities of participants in a Company equity incentive plan, a
registration relating to a corporate reorganization or transaction under Rule 145 of the Securities Act, a registration on any form
that does not include substantially the same information as would be required to be included in a registration statement covering
the sale of the Registrable Securities, or a registration in which the only Ordinary Shares being registered are Ordinary Shares
issuable upon conversion of debt securities that are also being registered), the Company shall, at such time, promptly give each
Holder written notice of such registration. Upon the written request of each Holder given within twenty (20) days after mailing of
such notice by the Company, the Company shall, subject to the provisions of Section 5.3(iii), use all commercially reasonable
efforts to cause to be registered under the Securities Act all of the Registrable Securities that each such Holder requests to be
registered.

(ii)

Right  to  Terminate  Registration.  The  Company  shall  have  the  right  to  terminate  or  withdraw  any
registration  initiated  by  it  under  this  Section 5.3  prior  to  the  effectiveness  of  such  registration  whether  or  not  any  Holder  has
elected to include securities in such registration. The expenses of such withdrawn registration shall be borne by the Company in
accordance with Section 5.7 hereof.

(iii)

Underwriting Requirements. If a registration statement under which the Company gives notice under this
Section  5.3  is  for  an  underwritten  offering,  the  Company  shall  not  be  required  under  this  Section  5.3  to  include  any  of  the
Holders’ securities in such underwriting unless they accept the terms of the underwriting as agreed upon between the Company
and  the  underwriters  selected  by  the  Company  (or  by  other  persons  entitled  to  select  the  underwriters)  and  enter  into  an
underwriting agreement in customary form with such underwriters, and then only in such quantity as the underwriters determine
in their sole discretion will not jeopardize the success of the offering by the Company. If the total amount of securities, including
Registrable  Securities,  requested  by  the  members  of  the  Company  to  be  included  in  such  offering  exceeds  the  amount  of
securities sold other than by the Company that the underwriters determine in their sole discretion is compatible with the success
of  the  offering,  then  the  Company  shall  be  required  to  include  in  the  offering  only  that  number  of  such  securities,  including
Registrable Securities, that the underwriters determine in their sole discretion will not jeopardize the success of the offering. In no
event  shall  any  Registrable  Securities  be  excluded  from  such  offering  unless  all  other  members’  securities  have  been  first
excluded. In the event that the underwriters determine that less than all of the Registrable Securities requested to be registered
can be included in such offering, then the Registrable Securities that are included in such offering shall be apportioned pro rata
among the selling Holders based on the number of Registrable Securities held by all selling Holders or in such

13

other proportions as shall mutually be agreed to by all such selling Holders. Notwithstanding the foregoing, in no event shall the
amount of securities of the selling Holders included in the offering be reduced below twenty percent (20%) of the total amount of
securities included in such offering, unless such offering is the IPO, in which case the selling Holders may be excluded if the
underwriters  make  the  determination  described  above  and  no  other  member’s  securities  are  included  in  such  offering.  For
purposes  of  the  preceding  sentence  concerning  apportionment,  for  any  selling  shareholder  that  is  a  Holder  of  Registrable
Securities  and  that  is  a  venture  capital  fund,  partnership  or  corporation,  the  affiliated  venture  capital  funds,  partners,  retired
partners and holders of such Holder, or the estates and family members of any such partners and retired partners and any trusts
for the benefit of any of the foregoing persons shall be deemed to be a single “selling Holder,” and any pro rata reduction with
respect to such “selling Holder” shall be based upon the aggregate amount of Registrable Securities owned by all such related
entities and individuals.

5.4

Form F-3 Registration. In case the Company shall receive from the Holders of at least fifteen percent (15%) of
the Registrable Securities (for purposes of this Section 5.4, the “F-3 Initiating Holders”) a written request or requests that the
Company effect a registration on Form F-3 (or an equivalent registration in a jurisdiction outside of the United States) and any
related qualification or compliance with respect to all or a part of the Registrable Securities owned by such Holder or Holders, the
Company shall:

(i)

promptly give written notice of the proposed registration, and any related qualification or compliance, to

all other Holders; and

(ii)

use  all  commercially  reasonable  efforts  to  effect,  as  soon  as  practicable,  such  registration  and  all  such
qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such
portion  of  such  Holders’  Registrable  Securities  as  are  specified  in  such  request,  together  with  all  or  such  portion  of  the
Registrable Securities of any other Holders joining in such request as are specified in a written request given within fifteen (15)
days after receipt of such written notice from the Company, provided, however, that the Company shall not be obligated to effect
any such registration, qualification or compliance, pursuant to this Section 5.4:

(a)

if Form F-3 is not available for such offering by the Holders;

(b)
if  the  Holders,  together  with  the  holders  of  any  other  securities  of  the  Company  entitled  to  inclusion  in
such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to
the public (net of any underwriters’ discounts or commissions) of less than US$ 5,000,000;

(c)
if the Company shall furnish to all Holders requesting a registration statement pursuant to this Section 5.4 a
certificate signed by the Company’s CEO or chairman of the Board stating that in the good faith judgment of the
Board,  it  would  be  seriously  detrimental  to  the  Company  and  its  members  for  such  registration  statement  to  be
effected at such time, in which event the Company shall have the right to defer such filing for a period of not more
than ninety (90) days after receipt of the request of the F-3 Initiating Holders, provided that such right shall be
exercised by the Company not more than

14

once in any twelve (12) month period and provided further that the Company shall not register any securities for
the account of itself or any other shareholder during such ninety (90) day period;

after  the  Company  has  effected  four  (4)  registrations  pursuant  to  this  Section 5.4,  and  such  registrations

(d)
have been declared or ordered effective;

if the Company has, within the six (6) month period preceding the date of such request, already effected a

(e)
registration for the Holders pursuant to this Section 5.4; or

(f)
in  any  particular  jurisdiction  in  which  the  Company  would  be  required  to  execute  a  general  consent  to
service  of  process  in  effecting  such  registration,  unless  the  Company  is  already  subject  to  service  in  such
jurisdiction  and  except  as  may  be  required  under  the  Securities  Act  or  pursuant  to  applicable  securities  laws  in
other jurisdictions, as the case may be.

(iii)

If  the  F-3  Initiating  Holders  intend  to  distribute  the  Registrable  Securities  covered  by  their  request  by
means of an underwriting, they shall so advise the Company as a part of their request made pursuant to this Section 5.4 and the
Company shall include such information in the written notice referred to in Section 5.4(i). The provisions of Section 5.2(ii) shall
be applicable to such request (with the substitution of Section 5.4 for references to Section 5.2).

(iv)

Subject to the foregoing, the Company shall use its commercially reasonable efforts to file a registration
statement covering the Registrable Securities and other securities so requested to be registered as soon as practicable after receipt
of the request or requests of the F-3 Initiating Holders. Registrations effected pursuant to this Section 5.4 shall not be counted as
requests for registration effected pursuant to Section 5.2.

5.5

Obligations of the Company. Whenever required under this Section 5 to effect the registration of any Registrable

Securities, the Company shall, as expeditiously as reasonably possible:

(i)

prepare and file with the Commission a registration statement with respect to such Registrable Securities
and use its commercially reasonable efforts to cause such registration statement to become effective, and keep such registration
statement effective for a period of up to ninety (90) days or, in the case of Registrable Securities registered under Form F-3 in
accordance  with  Rule  415  under  the  Securities  Act  or  a  successor  rule,  until  the  distribution  contemplated  in  the  registration
statement  has  been  completed;  provided,  however,  that  (i)  such  ninety  (90)  day  period  shall  be  extended  for  a  period  of  time
equal  to  the  period  any  Holder  refrains  from  selling  any  securities  included  in  such  registration  at  the  request  of  the
underwriter(s), and (ii) in the case of any registration of Registrable Securities on Form F-3 which are intended to be offered on a
continuous  or  delayed  basis,  such  ninety  (90)  day  period  shall  be  extended,  if  necessary,  to  keep  the  registration  statement
effective until all such Registrable Securities are sold;

(ii)

prepare  and  file  with  the  Commission  such  amendments  and  supplements  to  such  registration  statement

and the prospectus used in connection with such

15

registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of
all securities covered by such registration statement;

(iii)

furnish  to  the  Holders  such  number  of  copies  of  a  prospectus,  including  a  preliminary  prospectus,  in
conformity  with  the  requirements  of  the  Securities  Act,  and  such  other  documents  as  they  may  reasonably  request  in  order  to
facilitate the disposition of the Registrable Securities owned by them that are included in such registration;

(iv)

use all commercially reasonable efforts to register and qualify the securities covered by such registration
statement  under  such  other  securities  or  blue  sky  laws  of  such  jurisdictions  as  shall  be  reasonably  requested  by  the  Holders,
provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to
file a general consent to service of process in any such states or jurisdictions unless the Company is already subject to service in
such jurisdiction and except as may be required by the Securities Act;

(v)

in  the  event  of  any  underwritten  public  offering,  enter  into  and  perform  its  obligations  under  an

underwriting agreement in usual and customary form, with the managing underwriter(s) of such offering;

(vi)

notify  each  Holder  of  Registrable  Securities  covered  by  such  registration  statement  at  any  time  when  a
prospectus  relating  thereto  is  required  to  be  delivered  under  the  Securities  Act  of  (i)  the  issuance  of  any  stop  order  by  the
Commission  in  respect  of  such  registration  statement,  or  (ii)  the  happening  of  any  event  as  a  result  of  which  the  prospectus
included  in  such  registration  statement,  as  then  in  effect,  includes  an  untrue  statement  of  a  material  fact  or  omits  to  state  a
material  fact  required  to  be  stated  therein  or  necessary  to  make  the  statements  therein  not  misleading  in  the  light  of  the
circumstances then existing;

(vii)

cause  all  such  Registrable  Securities  registered  pursuant  to  this  Section 5  to  be  listed  on  each  securities

exchange on which similar securities issued by the Company are then listed, if any;

(viii) provide  a  transfer  agent  and  registrar  for  all  Registrable  Securities  registered  pursuant  hereunder  and  a

CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration.

Notwithstanding  the  provisions  of  this  Section  5,  the  Company  shall  be  entitled  to  postpone  or  suspend,  for  a
reasonable period of time, the filing, effectiveness or use of, or trading under, any registration statement if the Company shall
determine  that  any  such  filing  or  the  sale  of  any  securities  pursuant  to  such  registration  statement  would  in  the  good  faith
judgment of the Board: (i) materially impede, delay or interfere with any material pending or proposed financing, acquisition,
corporate reorganization or other similar transaction involving the Company for which the Board has authorized negotiations; (ii)
materially adversely impair the consummation of any pending or proposed material offering or sale of any class of securities by
the  Company;  or  (iii)  require  disclosure  of  material  nonpublic  information  that,  if  disclosed  at  such  time,  would  be  materially
harmful  to  the  interests  of  the  Company  and  its  shareholders;  provided,  however,  that  during  any  such  period  all  executive
officers and directors of the Company are also prohibited from selling

16

securities of the Company (or any security of any of the Company’s subsidiaries or affiliates). In the event of the suspension of
effectiveness of any registration statement pursuant to this Section 5.5, the applicable time period during which such registration
statement is to remain effective shall be extended by that number of days equal to the number of days the effectiveness of such
registration statement was suspended.

5.6

Information from Holder. It shall be a condition precedent to the obligations of the Company to take any action
pursuant to this Section 5 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the
Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such
securities as shall be reasonably required to effect the registration of such Holder’s Registrable Securities.

5.7

Expenses  of  Registration.  All  expenses  other  than  underwriting  discounts  and  commissions  incurred  in
connection  with  registrations,  filings  or  qualifications  pursuant  to  Sections  5.2,  5.3  and  5.4,  including,  without  limitation,  all
registration, filing and qualification fees, printers’ and accounting fees, fees and disbursements of counsel for the Company and
the reasonable fees and disbursements of one counsel for the selling Holders shall be borne by the Company. Notwithstanding the
foregoing, the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Section
5.2  or  Section  5.4  if  the  registration  request  is  subsequently  withdrawn  at  the  request  of  the  Holders  of  a  majority  of  the
Registrable Securities to be registered (in which case all participating Holders shall bear such expenses pro rata based upon the
number  of  Registrable  Securities  that  were  to  be  included  in  the  withdrawn  registration),  unless,  in  the  case  of  a  registration
requested under Section 5.2, the Holders of a majority of the Registrable Securities agree to forfeit their right to one (1) demand
registration pursuant to Section 5.2 and provided, however, that if at the time of such withdrawal, the Holders have learned of a
material adverse change in the condition, business or prospects of the Company from that known to the Holders at the time of
their request and have withdrawn the request with reasonable promptness following disclosure by the Company of such material
adverse  change,  then  the  Holders  shall  not  be  required  to  pay  any  of  such  expenses  and  shall  retain  their  rights  pursuant  to
Sections 5.2 and 5.4.

5.8

Delay of Registration. No  Holder  shall  have  any  right  to  obtain  or  seek  an  injunction  restraining  or  otherwise
delaying  any  such  registration  as  the  result  of  any  controversy  that  might  arise  with  respect  to  the  interpretation  or
implementation of this Section 3.

5.9

Indemnification. In the event any Registrable Securities are included in a registration statement under this Section

5:

(i)

To the extent permitted by applicable law, the Company will indemnify and hold harmless each Holder and
its  Affiliates,  its  and  their  partners,  officers,  directors,  legal  counsel  and  accountants,  and  any  underwriter  (as  defined  in  the
Securities  Act)  for  such  person  and  each  person,  if  any,  who  controls  such  person  or  underwriter  within  the  meaning  of  the
Securities  Act  or  the  Exchange  Act,  against  any  losses,  claims,  damages,  or  liabilities  (joint  or  several)  to  which  they  may
become  subject  under  the  Securities  Act,  the  Exchange  Act  or  other  United  States  federal  or  state  law,  insofar  as  such  losses,
claims,

17

damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or
violations (collectively a “Violation”): (i) any untrue statement or alleged untrue statement of a material fact contained in such
registration  statement,  including  any  preliminary  prospectus  or  final  prospectus  contained  therein  or  any  amendments  or
supplements  thereto;  (ii)  the  omission  or  alleged  omission  to  state  therein  a  material  fact  required  to  be  stated  therein,  or
necessary  to  make  the  statements  therein  not  misleading;  or  (iii)  any  violation  or  alleged  violation  by  the  Company  of  the
Securities Act, the Exchange Act, any United States federal or state securities law or any rule or regulation promulgated under the
Securities Act, the Exchange Act or any United States federal or state securities law in connection with the offering covered by
such  registration  statement;  and  the  Company  will  reimburse  each  such  Holder,  underwriter,  controlling  person  or  other
aforementioned person for any legal or other expenses reasonably incurred by them in connection with investigating or defending
any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the indemnity agreement
contained in this Section 5.9(i) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if
such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the
Company be liable in any such case for any such loss, claim, damage, liability or action to the extent that it arises out of or is
based upon a Violation that occurs in reliance upon and in conformity with written information furnished expressly for use in
connection with such registration by any such Holder, underwriter, controlling person or other aforementioned person.

(ii)

To  the  extent  permitted  by  law,  each  selling  Holder,  severally  and  not  jointly,  will  indemnify  and  hold
harmless the Company, each of its directors, each of its officers who has signed the registration statement, each person, if any,
who  controls  the  Company  within  the  meaning  of  the  Securities  Act,  legal  counsel  and  accountants  for  the  Company,  any
underwriter, any other Holder selling securities in such registration statement and any controlling person of any such underwriter
or other Holder, against any losses, claims, damages or liabilities (joint or several) to which any of the foregoing persons may
become subject, under the Securities Act, the Exchange Act or other United States federal or state law, insofar as such losses,
claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent
(and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such
Holder expressly for use in connection with such registration; and each such Holder will reimburse any person intended to be
indemnified pursuant to this Section 5.9(ii) for any legal or other expenses reasonably incurred by such person in connection with
investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that
the indemnity agreement contained in this Section 5.9(ii) shall not apply to amounts paid in settlement of any such loss, claim,
damage,  liability  or  action  if  such  settlement  is  effected  without  the  consent  of  the  Holder  (which  consent  shall  not  be
unreasonably withheld), and provided that in no event shall any indemnity under this Section 5.9(ii) exceed the net proceeds from
the offering received by such Holder.

(iii)

Promptly after receipt by an indemnified party under this Section 5.9 of notice of the commencement of
any action (including any governmental action) for which a party may be entitled to indemnification, such indemnified party will,
if a claim in respect thereof is to be made against any indemnifying party under this Section 5.9, deliver to the

18

indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in
and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the
defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all
other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one (1) separate
counsel,  with  the  fees  and  expenses  to  be  paid  by  the  indemnifying  party,  if  representation  of  such  indemnified  party  by  the
counsel  retained  by  the  indemnifying  party  would  be  inappropriate  due  to  actual  or  potential  differing  interests  between  such
indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such action, if prejudicial to its ability to defend such
action,  shall  relieve  such  indemnifying  party  of  liability  to  the  indemnified  party  under  this  Section  5.9  to  the  extent  of  such
prejudice, but the omission to so deliver written notice to the indemnifying party will not relieve it of any liability that it may
have to any indemnified party otherwise than under this Section 5.9.

(iv)

If  the  indemnification  provided  for  in  this  Section 5.9  is  held  by  a  court  of  competent  jurisdiction  to  be
unavailable  to  an  indemnified  party  with  respect  to  any  loss,  liability,  claim,  damage  or  expense  referred  to  herein,  then  the
indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect
the relative fault of the indemnifying party on the one hand and the indemnified party on the other hand in connection with the
statements  or  omissions  that  resulted  in  such  loss,  liability,  claim,  damage  or  expense,  as  well  as  any  other  relevant  equitable
considerations; provided, however, that (i) no contribution by any Holder, when combined with any amounts paid by such Holder
pursuant to Section 5.9(ii), shall exceed the net proceeds from the offering received by such Holder and (ii) no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation; and provided further that in no event shall a Holder’s liability
pursuant to this Section 5.9(iv),  when  combined  with  the  amounts  paid  or  payable  by  such  Holder  pursuant  to  Section 5.9(ii),
exceed the proceeds from the offering received by such Holder (net of any expenses paid by such Holder). The relative fault of
the indemnifying party and the indemnified party shall be determined by reference to, among other things, whether the untrue or
alleged  untrue  statement  of  a  material  fact  or  the  omission  or  alleged  omission  to  state  a  material  fact  relates  to  information
supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

(v)

The  obligations  of  the  Company  and  Holders  under  this  Section 5.9  shall  survive  the  completion  of  any

offering of Registrable Securities in a registration statement under this Section 5 and otherwise.

5.10 Rule 144 Reporting. With a view to making available to the Holders the benefits of SEC Rule 144 and any other
rules and regulations of the Commission which may at any time permit a Holder to sell the Registrable Securities to the public
without registration or pursuant to a registration on Form F-3, the Company agrees to

19

(i)

make and keep public information available, as those terms are understood and defined in SEC Rule 144,

at all times after the effective date of the IPO;

(ii)

file  with  the  Commission  in  a  timely  manner  all  reports  and  other  documents  required  of  the  Company

under the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements); and

(iii)

so long as a Holder owns any Registrable Securities, furnish to such Holder forthwith upon request (i) a
written statement by the Company that it has complied with the reporting requirements of SEC Rule 144 (at any time after ninety
(90) days after the effective date of the first registration statement filed by the Company), the Securities Act and the Exchange
Act (at any time after it has become subject to such reporting requirements), or that it qualifies as a registrant whose securities
may be resold pursuant to Form F-3 (at any time after it so qualifies), (ii) a copy of the most recent annual or quarterly report of
the  Company  and  such  other  reports  and  documents  so  filed  by  the  Company,  and  (iii)  such  other  information  as  may  be
reasonably  requested  to  avail  any  Holder  of  any  rule  or  regulation  of  the  Commission  that  permits  the  selling  of  any  such
securities without registration or pursuant to such form.

5.11 Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities pursuant
to this Section 5 may be assigned (but only with all related obligations) by a Holder to a transferee or assignee of such securities
that (a) is an Affiliate, subsidiary, parent, partner, limited partner, retired partner or shareholder of a Holder or (b) is a Holder’s
immediate family member (spouse or child) or trust for the benefit of an individual Holder; provided: (i) the Company is, within
a reasonable time after such transfer, furnished with written notice of the name and address of such transferee or assignee and the
securities with respect to which such registration rights are being assigned; (ii) such transferee or assignee agrees in writing to be
bound by and subject to the terms and conditions of this Agreement, including, without limitation, the provisions of Section 5.13
below;  and  (iii)  such  assignment  shall  be  effective  only  if  immediately  following  such  transfer  the  further  disposition  of  such
securities by the transferee or assignee is restricted under the Securities Act.

5.12 Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall
not,  without  the  prior  written  consent  of  the  Holders  holding  at  least  two-thirds  of  the  Registrable  Securities  then  held  by  all
Holders, enter into any agreement with any holder or prospective holder of any securities of the Company that would allow such
holder or prospective holder (a) to include any of such securities in any registration filed under Section 5.2, Section 5.3 or Section
5.4 hereof, unless under the terms of such agreement, such holder or prospective holder may include such securities in any such
registration only to the extent that the inclusion of such securities will not reduce the amount of the Registrable Securities of the
Holders that are included or (b) to demand registration of their securities.

5.13

“Market Stand-Off” Agreement. Each Holder agrees, if so required by the managing underwriter(s), that it will
not  during  the  period  commencing  on  the  date  of  the  final  prospectus  relating  to  the  Company’s  IPO  and  ending  on  the  date
specified by the Company and the managing underwriter (such period not to exceed one hundred eighty (180)

20

days from the date of such final prospectus), (i) lend, charge, mortgage, offer, pledge, hypothecate, hedge, sell, make any short
sale of, loan, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option,
right  or  warrant  to  purchase,  or  otherwise  transfer  or  dispose  of,  directly  or  indirectly,  any  Equity  Securities  of  the  Company
owned immediately prior to the date of the final prospectus relating to the IPO (other than those included in such offering), or (ii)
enter  into  any  swap  or  other  arrangement  that  transfers  to  another,  in  whole  or  in  part,  any  of  the  economic  consequences  of
ownership of such Equity Securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery
of Equity Securities of the Company or such other securities, in cash or otherwise; provided, that (a) the foregoing provisions of
this  Section  shall  not  apply  to  the  sale  of  any  securities  of  the  Company  to  an  underwriter  pursuant  to  any  underwriting
agreement,  and  shall  not  be  applicable  to  any  Holder  unless  all  directors,  officers  and  all  other  holders  of  at  least  one  percent
(1%) of the outstanding share capital of the Company (calculated on an as-converted to Ordinary Share basis) must be bound by
restrictions at least as restrictive as those applicable to any such Holder pursuant to this Section, (b) this Section shall not apply to
an Holder to the extent that any other Person subject to substantially similar restrictions is released in whole or in part, and (c) the
lockup agreements shall permit an Holder to transfer its Equity Securities to its Affiliates so long as the transferees enter into the
same  lockup  agreement.  Each  Holder  agrees  to  execute  and  deliver  to  the  underwriters  a  lock-up  agreement  containing
substantially similar terms and conditions as those contained herein. In order to enforce the foregoing covenant, the Company
may place restrictive legends on the certificates and impose stop-transfer instructions with respect to such Equity Securities of
each Holder (and the shares or securities of every other Person subject to the foregoing restriction) until the end of such period.
Any discretionary waiver or termination of the restrictions of any or all of such agreements by the Company or the underwriters
shall apply pro rata to all Company stockholders that are subject to such agreements, based on the number of shares subject to
such agreements.

5.14 Hong Kong Offering. If the Company shall be actively pursuing a listing on the Hong Kong Stock Exchange, the
Company can restrict or otherwise prohibit the sale or transfer of any of its equity securities if, in the good faith determination of
the Board, (a) such sale or transfer or the related payment or settlement therefor is proposed to or will occur during the 28-day
period ending on the date immediately prior to the date of the Company’s planned first submission of its first listing application
form with the Hong Kong Stock Exchange (or such other relevant period as promulgated by the Hong Kong Stock Exchange or
applicable  Hong  Kong  securities  regulators)  or  (b)  such  sale  or  transfer,  after  consulting  the  Company’s  legal  counsel  and
sponsor(s) for the listing, may result in the delay of the Company’s planned timetable for the planned listing.

(i)

In  the  event  of  any  share  dividend,  share  split,  recapitalization  or  other  change  affecting  the  Company’s
outstanding  Ordinary  Shares  effected  without  receipt  of  consideration,  then  any  new,  substituted  or  additional  securities
distributed with respect to the Shares shall be immediately subject to the provisions of this Section 5.14, to the same extent the
Shares are at such time covered by such provisions.

21

(ii)

In order to enforce the limitations of this Section 5.14, the Company may impose stop-transfer instructions

with respect to the Shares until the end of the applicable stand-off period.

5.15 Termination of Registration Rights. No Holder shall be entitled to exercise any right provided for in this Section
5 (a) after five (5) years following the consummation of the QIPO; (b) as to any Holder, such earlier time at which all Registrable
Securities held by such Holder (and any Affiliate of the Holder with whom such Holder must aggregate its sales under SEC Rule
144) can be sold in any three (3)-month period without registration in compliance with SEC Rule 144; or (c) upon a liquidation,
winding up or dissolution of the Company or a Deemed Liquidation Event.

6.

Information and Inspection Rights.

6.1

Delivery of Financial Statements. The Company shall deliver to each Rights Holder the following documents or

reports:

(i)

within ninety (90) days after the end of each fiscal year of the Company, a consolidated income statement
and statement of cash flows for the Group for such fiscal year and a consolidated balance sheet for the Group as of the end of the
fiscal  year,  audited  and  certified  by  a  firm  of  independent  certified  public  accountants  and  all  prepared  in  English  and  in
accordance with the Accounting Standards consistently applied throughout the period;

(ii)

within  thirty  (30)  days  after  the  end  of  each  quarter  of  each  fiscal  year  of  the  Company,  unaudited
statements of income and cash flows of the Group for such fiscal quarter on a consolidated basis, and an unaudited balance sheet
for  the  Group  as  of  the  end  of  such  fiscal  quarter,  all  prepared  in  English  and  in  accordance  with  the  Accounting  Standards
consistently applied throughout the period (except for customary year-end adjustments and except for the absence of notes); and

(iii)

an annual business and financial plan for the following fiscal year, including a comprehensive operating
budget forecasting the Company’s revenues, expenses and cash position, no less than sixty (60) days prior to the beginning of
such  fiscal  year,  in  reasonable  detail  on  a  monthly  basis,  broken  down  by  different  operating  subsidiaries  and  associated
companies.

6.2

Inspection Rights. The Company covenants and agrees that each Rights Holder shall have the right, to reasonably
inspect the books and records of each Group Company at any time during regular working hours and in a manner so as not to
interfere  with  the  normal  business  operations  of  the  Group  Company  on  reasonable  prior  notice  to  such  Group  Company,
provided  that  such  Rights  Holder  shall  bear  the  costs  for  its  own  representatives  and  that  such  inspection  shall  not  be  more
frequent than once a year. Notwithstanding anything to the contrary herein, each Rights Holder may make reasonable requests for
financial  information  that  is  reasonably  necessary  for  such  Rights  Holder’s  or  any  of  its  Affiliate’s  applicable  financial
statements, including for any filings of financial statements under the Exchange Act, and the Company shall promptly respond to
such requests.

22

7.7

Preemptive Right.

7.1

General. The Company hereby grants to each holder of Ordinary Shares issued or issuable upon conversion of the
Preferred Shares for so long as such holder is not a Defaulting Shareholder (each, a “Rights Holder”) the right of first refusal to
purchase such Rights Holder’s Pro Rata Share (as defined below) (and any oversubscription, as provided below), of all (or any
part) of any New Securities (as defined below) that the Company may from time to time issue after the date of this Agreement
(the “Preemptive Right”).

7.2

Pro Rata Share. A Rights Holder’s “Pro Rata Share” for purposes of the Preemptive Rights is the ratio of (a) the
number  of  Ordinary  Shares  (including  Preferred  Shares  on  an  as-converted  basis)  held  by  such  Rights  Holder,  to  (b)  the  total
number  of  Ordinary  Shares  (including  Preferred  Shares  on  an  as-converted  basis)  then  outstanding  immediately  prior  to  the
issuance of New Securities giving rise to the Preemptive Rights.

7.3

New Securities. For purposes hereof, “New Securities” shall mean any Equity Securities of the Company issued

after the Closing (as defined in the Share Purchase Agreement), except for:

(i)

the  Ordinary  Shares  and/or  options  or  warrants  therefor  issued  to  employees,  officers,  directors,
contractors,  advisors  or  consultants  of  the  Group  pursuant  to  the  Company’s  employee  share  option  plans  (“ESOP”)  duly
approved by the Board, including the Allogene Designees and the Overland Designees;

(ii)

any  Equity  Securities  of  the  Company  issued  in  connection  with  any  share  split,  share  dividend,

reclassification or other similar event;

(iii)

any  Ordinary  Shares  issued  pursuant  to  bona  fide  transactions  with  commercial  lenders  or  lessors  in
connection  with  loans,  credit  arrangements,  equipment  financings  or  similar  transactions,  each  such  transaction  having  been
approved by the Board, including the Allogene Designees and the Overland Designees;

(iv)

any Equity Securities of the Company issued pursuant to the acquisition of another corporation or entity by
the Company by consolidation, merger, purchase of assets, or other reorganization in which the Company acquires, in a single
transaction or series of related transactions, all or substantially all assets of such other corporation or entity, or fifty percent (50%)
or more of the equity ownership or voting power of such other corporation or entity, in any case, duly approved by the Board,
including the Allogene Designees and the Overland Designees;

(v)

any Equity Securities of the Company issued pursuant to the Company’s IPO;

(vi)

any Ordinary Shares issued upon the conversion of the Preferred Shares; and

(vii)

any Seed Preferred Shares issued pursuant to the Share Purchase Agreement.

23

7.4

Procedures.  In  the  event  that  the  Company  proposes  to  undertake  an  issuance  of  New  Securities  (in  a  single
transaction  or  a  series  of  related  transactions),  it  shall  give  to  each  Rights  Holder  written  notice  of  its  intention  to  issue  New
Securities (the “Participation Notice”), describing the amount and type of New Securities, the price and the general terms upon
which the Company proposes to issue such New Securities. Each Rights Holder shall have fifteen (15) Business Days from the
date of receipt of any such Participation Notice (the “Notice Period”) to agree in writing to purchase up to such Rights Holder’s
Pro Rata Share of such New Securities for the price and upon the terms and conditions specified in the Participation Notice by
giving  written  notice  to  the  Company  and  stating  therein  the  quantity  of  New  Securities  to  be  purchased  (not  to  exceed  such
Rights Holder’s Pro Rata Share). If any Rights Holder fails to so respond in writing within the Notice Period, then such Rights
Holder shall forfeit the right hereunder to purchase its Pro Rata Share of such New Securities. Upon the expiration of the Notice
Period, the purchaser(s) to which the Company proposes to issue New Securities may, within fifteen (15) Business Days after the
expiration of the Notice Period, elect to purchase in aggregate all or any portion of the Available New Securities at the same or
higher price and upon nonprice terms not more favorable to the purchasers thereof than specified in the Participation Notice (for
the purposes of this Section 7.4, the number of “Available New Securities” equals (a) the total number of New Securities that the
Company intends to issue as described in the Participation Notice less (b) the number of New Securities that the Rights Holders
elect to purchase pursuant to the foregoing). In the event that the purchaser(s) does not elect to purchase in aggregate all of the
Available New Securities, immediately after fifteen (15) Business Days of the expiration of the Notice Period, the Company shall
promptly  notify  each  Rights  Holder  that  elects  to  purchase  or  acquire  all  the  shares  available  to  it  (each,  a  “Fully Exercising
Shareholder”)  of  the  number  of  Remaining  New  Securities  (for  the  purposes  of  this  Section 7.4,  the  number  of  “Remaining
New Securities” equals (x) the total number of New Securities that the Company intends to issue as described in the Participation
Notice  less  (y)  the  number  of  New  Securities  that  the  Rights  Holders  and  the  purchaser(s)  elect  to  purchase  pursuant  to  the
foregoing).  During  the  ten  (10)  day  period  commencing  after  the  Company  has  given  such  notice,  each  Fully  Exercising
Shareholder may, by giving notice to the Company, elect to purchase or acquire, in addition to the number of shares specified
above, up to that portion of the Remaining New Securities which is equal to the proportion that the Ordinary Shares issued and
held,  or  issuable  (directly  or  indirectly)  upon  conversion  and/or  exercise,  as  applicable,  of  Preferred  Shares,  by  such  Fully
Exercising Shareholder bears to the Ordinary Shares issued and held, or issuable (directly or indirectly) upon conversion and/or
exercise,  as  applicable,  of  the  Preferred  Shares  then  held,  by  all  Fully  Exercising  Shareholders  who  wish  to  purchase  such
Remaining New Securities. The closing of any sale pursuant to this Section 7.4 shall occur within one hundred and twenty (120)
days of the expiration of the Participation Notice. In the event that the Company has not issued and sold such New Securities
within such one hundred and twenty (120) days period, then the Company shall not thereafter issue or sell any New Securities
without again first offering such New Securities to the Rights Holders pursuant to this Section 7.4.

8.

Limitations on Disposition.

8.1

Transfer Restrictions. Each Shareholder agrees that, for a period of 7 years from the date of this Agreement, such
Shareholder shall not, directly or indirectly, sell, assign, transfer, pledge, hypothecate, or otherwise encumber or dispose of in any
way or

24

otherwise grant any interest or right (“Transfer”) to any Third Party with respect to all or any part of any interest in any Equity
Securities owned or held by such Shareholder (each a “Transferor”) without the prior written consent of the other Shareholder.

8.2

Prohibited Transfers Void. Any Transfer of Equity Securities of the Company not made in compliance with this
Section 8 shall be null and void as against the Company, shall not be recorded on the books of the Company and shall not be
recognized by the Company or any other Party.

8.3

No Indirect Transfers. Each Transferor agrees not to circumvent or otherwise avoid the transfer restrictions or
intent  thereof  set  forth  in  this  Section 8,  whether  by  holding  the  Equity  Securities  of  the  Company  indirectly  through  another
Person or by causing or effecting, directly or indirectly, the Transfer or issuance of any Equity Securities by any such Person, or
otherwise.  Any  purported  Transfer,  sale  or  issuance  of  any  Equity  Securities  of  any  company  held  by  any  Transferor  holding
Shares in the Company (a “Holding Company”) in contravention of this Agreement shall be void and ineffective for any and all
purposes and shall not confer on any transferee or purported transferee any rights whatsoever, and no Party (including without
limitation, any Transferor or Holding Company) shall recognize any such Transfer, sale or issuance.

9.

Additional Covenants.

9.1

Accounting  Standards;  Fiscal  Year;  Internal  Controls.  The  Company  shall  cause  the  Group  Companies  to
adopt  and  maintain  December  31  as  their  fiscal  year  end  and  will  maintain  their  books  and  records  in  accordance  with  sound
business  practices  and  implement  and  maintain  an  adequate  system  of  procedures  and  controls  with  respect  to  finance,
management, and accounting that meets international standards of good practice and is reasonably satisfactory to the Board to

Confidentiality.

25

(i)

The  terms  and  conditions  of  the  Transaction  Documents,  including  their  existence,  and  any  information
obtained from the Company pursuant to the terms of the Transaction Documents or otherwise (collectively,  the  “Confidential
Information”) shall be considered confidential information and shall not be disclosed by any of the Parties to any other Person
(including,  without  limitation,  any  portfolio  company  of  the  Overland  Group  or  any  other  Overland  Party)  unless  such
Confidential  Information  (a)  is  known  or  becomes  known  to  the  public  in  general  (other  than  as  a  result  of  a  breach  of  this
Section 9.3(i)  by  such  Party),  (b)  is  or  has  been  independently  developed  or  conceived  by  the  Shareholder  without  use  of  the
Company’s Confidential Information, or (c) is or has been made known or disclosed to the Party by a third party without a breach
of any obligation of confidentiality such third party may have to the other Parties, and except that (x) each Party, as appropriate,
may  disclose  any  of  the  Confidential  Information  to  its  current  or  bona  fide  prospective  investors,  prospective  permitted
transferees, employees, investment bankers, lenders, accountants and attorneys, in each case only where such Persons are under
commercially reasonable nondisclosure obligations; (y) the Shareholder may disclose any of the Confidential Information to its
fund manager and the employees thereof so long as such Persons are under commercially reasonable nondisclosure obligations;
and (z) if any Party is requested or becomes legally compelled (including without limitation, pursuant to the applicable securities
laws)  to  disclose  the  existence  or  content  of  any  of  the  Confidential  Information  in  contravention  of  the  provisions  of  this
Section, such Party shall, to the extent permitted by applicable Law, promptly provide the other Parties with written notice of that
fact so that such other Parties may seek a protective order, confidential treatment or other appropriate remedy and in any event
shall furnish only that portion of the information that is legally required and shall exercise reasonable efforts to obtain reliable
assurance that confidential treatment will be accorded such information.

(ii)

The provisions of this Section shall terminate and supersede the provisions of any separate nondisclosure
agreement  executed  by  any  of  the  Parties  hereto  with  respect  to  the  transactions  contemplated  hereby,  including  without
limitation,  any  term  sheet,  letter  of  intent,  memorandum  of  understanding  or  other  similar  agreement  entered  into  by  the
Company and the Shareholders in respect of the transactions contemplated hereby.

9.4

Anti-Bribery  Compliance.  The  Company  agrees  and  covenants  to  make  reasonable  efforts  to  ensure  that  the
Group: (i) complies with all applicable anti-bribery and anti-corruption laws and regulations, including, but not limited to, the
U.S. Foreign Corrupt Practices Act and the UK Bribery Act and (ii) implements reasonable policies and procedures designed to
prevent any Group Company, or any person acting on its or their behalf, from making any Prohibited Payment in connection with
the activities or operations of any of the Group Companies. For purposes of this Section “Prohibited Payment” means (a) any
offer, gift, payment, promise to pay or authorization of the payment of any money or anything of value, directly or indirectly, to
or for the use or benefit of any Public Official (including to or for the use or benefit of any other person if a Group Company
knows,  or  has  reasonable  grounds  for  believing,  that  the  other  person  would  use  such  offer,  gift,  payment,  promise  or
authorization  of  payment  for  the  benefit  of  any  such  Public  Official),  for  the  purpose  of  influencing  any  act  or  decision  or
omission of any Public Official in order to obtain, retain or direct business to, or to secure any improper benefit or advantage for,
a  Group  Company  or  any  other  person,  or  (b)  any  conduct  constituting  a  violation  of  applicable  Law  involving  corruption  or
bribery; provided that any such offer, gift, payment, promise or authorization of

26

payment shall not be considered a Prohibited Payment if it is lawful under applicable written laws and regulations, and “Public
Official” means any executive, official, or employee of a Governmental Authority, political party or member of a political party,
political candidate; executive, employee or officer of a public international organization; or director, officer or employee or agent
of a wholly owned or partially state-owned or controlled enterprise.

9.5

Insurance.  The  Company  shall  obtain,  within  ninety  (90)  days  of  the  date  hereof,  from  financially  sound  and
reputable insurers in the Company’s reasonable judgment, directors and officers liability insurance in an amount and on terms and
conditions  satisfactory  to  the  Board,  and  will  use  commercially  reasonable  efforts  to  cause  such  insurance  policies  to  be
maintained until such time as the Board determines that such insurance should be discontinued.

9.6

Indemnification Matters. The Company hereby acknowledges that one (1) or more of Preferred Directors may
have certain rights to indemnification, advancement of expenses and/or insurance provided by one or more of the Shareholders
and  certain  of  their  Affiliates  (collectively,  the  “Shareholder  Indemnitors”).    The  Company  hereby  agrees  (i)  that  it  is  the
indemnitor of first resort (i.e., its obligations to any such Preferred Director are primary and any obligation of the Shareholder
Indemnitors  to  advance  expenses  or  to  provide  indemnification  for  the  same  expenses  or  liabilities  incurred  by  such  Preferred
Director are secondary), (ii) that it shall be required to advance the full amount of expenses incurred by such Preferred Director
and shall be liable for the full amount of all expenses, judgments, penalties, fines and amounts paid in settlement by or on behalf
of  any  such  Preferred  Director  to  the  extent  legally  permitted  and  as  required  by  the  Memorandum  and  Articles  (or  any
agreement between the Company and such Preferred Director), without regard to any rights such Preferred Director may have
against the Shareholder Indemnitors, and (iii) that it irrevocably waives, relinquishes and releases the Shareholder Indemnitors
from any and all claims against the Shareholder Indemnitors for contribution, subrogation or any other recovery of any kind in
respect thereof.  The Company further agrees that no advancement or payment by the Shareholder Indemnitors on behalf of any
such  Preferred  Director  with  respect  to  any  claim  for  which  such  Preferred  Director  has  sought  indemnification  from  the
Company shall affect the foregoing and the Shareholder Indemnitors shall have a right of contribution and/or be subrogated to the
extent  of  such  advancement  or  payment  to  all  of  the  rights  of  recovery  of  such  Preferred  Director  against  the  Company.  The
Preferred Directors and the Shareholder Indemnitors are intended thirdparty beneficiaries of this Section 9.6 and shall have the
right, power and authority to enforce the provisions of this Section 9.6 as though they were a party to this Agreement.

9.7

Employee Agreements. The Company will cause (i) each Person now or hereafter employed by it or by any of its
subsidiaries (or engaged by the Company or any subsidiary as a consultant/independent contractor) with access to confidential
information and/or trade secrets to enter into a nondisclosure and proprietary rights assignment agreement; and (ii) subject to the
applicable Law, such Person to enter into a noncompetition and nonsolicitation agreement, in each case substantially in the form
approved  by  the  Board,  including  the  Allogene  Designees  and  the  Overland  Designees.  In  addition,  the  Company  shall  not
amend, modify, terminate, waive, or otherwise materially alter, in whole or in part, any of the above-referenced agreements or
any restricted stock agreement between the Company and any such Person, without the consent of the Board.

27

9.8

Employee Stock. Unless otherwise approved by the Board, all future employees and consultants of the Company
who purchase, receive options to purchase, or receive awards of shares of the Company’s capital stock after the date hereof shall
be required to execute restricted stock or option agreements, as applicable, providing for (i) vesting of shares over a four (4) year
period, with the first twenty-five percent (25%) of such shares vesting following twelve (12) months of continued employment or
service,  and  the  remaining  shares  vesting  in  equal  monthly  installments  over  the  following  thirty-six  (36)  months,  and  (ii)  a
market stand-off provision substantially similar to that in Section 3. Without the prior approval by the Board, the Company shall
not  amend,  modify,  terminate,  waive  or  otherwise  alter,  in  whole  or  in  part,  any  stock  purchase,  stock  restriction  or  option
agreement with any existing employee or service provider if such amendment would cause it to be inconsistent with this Section
9.8. In addition, unless otherwise approved by the Board, the Company shall retain (and not waive) a “right of first refusal” on
employee transfers until the Company’s IPO and shall have the right to repurchase unvested shares at cost upon termination of
employment of a holder of restricted stock.

9.9

Successor Indemnification. If the Company or any of its successors or assignees consolidates with or merges into
any other Person and is not the continuing or surviving corporation or entity of such consolidation or merger, then to the extent
necessary,  proper  provision  shall  be  made  so  that  the  successors  and  assignees  of  the  Company  assume  the  obligations  of  the
Company  with  respect  to  indemnification  of  members  of  the  Board  as  in  effect  immediately  before  such  transaction,  whether
such obligations are contained in the Memorandum and Articles, or elsewhere, as the case may be.

9.10

[***].

9.11 Related Party Litigation. In the case of any Related Party Litigation, or facts upon which such an action could be
commenced, and upon notification to the Company, the Investor Directors not appointed by the Related Party against whom such
Related  Party  Litigation  has  been  or  could  be  commenced  shall  be  exclusively  entitled,  on  behalf  of  the  Company,  to  initiate,
control, or abandon any such Related Party Litigation, to settle any claims related thereto, and/or to expend reasonable Company
resources in the furtherance of the same regardless of whether such resources are provided in the Annual Business Plan.

10. Miscellaneous.

10.1 Termination.  This  Agreement  shall  terminate  upon  mutual  consent  of  the  Parties  hereto.  The  provisions  of
Sections 2, 3, 4, 6, 7, 8 and 9 (except for 6.2, 9.3, 9.6, 9.9, and 9.10)  shall  terminate  on  the  earliest  of  the  consummation  of  a
QIPO or a Deemed Liquidation Event. If this Agreement terminates, the Parties shall be released from their obligations under this
Agreement, except in respect of any obligation stated, explicitly or otherwise, to continue to exist after the termination of this
Agreement. This Agreement shall terminate with respect to any shareholder of the Company when such shareholder no longer
holds any Shares. If any Party breaches this Agreement before the termination of this Agreement, it shall not be released from its
obligations arising from such breach on termination.

10.2

[***] Overland shall become a “Defaulting Shareholder” in the event of [***].

28

10.3

Further Assurances. Upon the terms and subject to the conditions herein, each of the Parties hereto agrees to use
its reasonable best efforts to take or cause to be taken all action, to do or cause to be done, to execute such further instruments,
and to assist and cooperate with the other Parties hereto in doing, all things necessary, proper or advisable under applicable Laws
or otherwise to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated by
this Agreement.

10.4 Assignments  and  Transfers;  No  Third  Party  Beneficiaries.  For  7  years  after  the  Effective  Date,  neither
Overland nor Allogene may assign this Agreement and rights and obligations hereunder without the other Party’s prior written
consent, unless (i) to an Affiliate, so long as such Person remains an Affiliate of the transferring Shareholder and the transferring
Shareholder remains fully responsible and liable for any action and inaction of its Affiliate or (ii) to a Third Party that acquires
(whether by merger, reorganization, acquisition, sale or otherwise) (a) in the case of Allogene as the transferring Shareholder, all
or substantially all of the assets of Allogene in the Competing Business or all or substantially all of the equity of Allogene, or (b)
all or substantially all of the assets or equity of the transferring Shareholder; provided in each case, the transferring Party shall
provide  prior  notice  to  the  other  Shareholder  and  the  Company.  Except  as  otherwise  provided  herein,  this  Agreement  and  the
rights  and  obligations  of  the  Parties  hereunder  shall  inure  to  the  benefit  of,  and  be  binding  upon,  their  respective  permitted
successors, assigns and legal representatives, but shall not otherwise be for the benefit of any Third Party. In the event the rights
of  any  Shareholder  hereunder  (including,  without  limitation,  registration  rights)  are  assigned  (together  with  the  related
obligations) to a permitted Third Party in accordance with this Section 10.4, such permitted transferee shall execute and deliver to
the  Company  a  deed  of  adherence  or  joinder  becoming  a  party  hereto  as  a  “Shareholder”  subject  to  the  terms  and  conditions
hereof (if not already so bound). This Agreement and the rights and obligations of each other Party hereunder shall not otherwise
be assigned without the mutual written consent of the other Parties except as expressly provided herein.

10.5 Governing  Law.  This  Agreement  and  all  actions  arising  out  of  or  in  connection  with  this  Agreement  shall  be
governed  by  and  construed  in  accordance  with  the  Laws  of  the  State  of  New  York,  without  regard  to  the  conflicts  of  Law
provisions thereof or of any other jurisdiction which would result in the application of the Laws of any other jurisdiction.

10.6 Dispute Resolution.

(i)

Disputes. Subject to Section 10.6(iii), upon the written request of any Party to any other Party, any claim,
dispute, or controversy as to the breach, enforcement, interpretation or validity of this Agreement (a “Dispute”) will be referred
to the chief executive officers of the disputing Parties (or their designee with decision-making authority of at least senior vice
president level) for attempted resolution. In the event such executives or their designees are unable to resolve such Dispute within
sixty (60) days after the initial written request, then, upon the written demand of any disputing Party, the Dispute shall be subject
to arbitration, as provided in Section 10.6(ii), except as expressly set forth in Section 10.6(iii).

(ii)

Arbitration.

29

Claims.  Subject  to  Section 10.6(iii)  below,  any  Dispute  that  is  not  resolved  under  Section 10.6(i)  within
(a)
thirty (30) days after a disputing Party’s initial written request for resolution, shall be resolved by final and binding
arbitration  before  a  panel  of  three  neutral  experts  with  relevant  industry  experience.  The  arbitration  proceeding
shall  be  administered  by  the  International  Court  of  Arbitration  of  the  International  Chamber  of  Commerce  (the
“ICC”)  in  accordance  with  its  then  existing  arbitration  rules  or  procedures  regarding  commercial  or  business
disputes,  and  the  panel  of  arbitrators  shall  be  selected  in  accordance  with  such  rules.  The  arbitration  and  all
associated discovery proceedings and communications shall be conducted in English, and the arbitration shall be
held in New York. Except  to  the  extent  necessary  to  confirm  an  award  or  as  may  be  required  by  law,  neither  a
Party  nor  an  arbitrator  may  disclose  the  existence,  content,  or  results  of  arbitration  without  the  prior  written
consent of the disputing Parties.

(b)
Arbitrators’  Award.  The  arbitrators  shall,  within  fifteen  (15)  days  after  the  conclusion  of  the  arbitration
hearing,  issue  a  written  award  and  statement  of  decision  describing  the  essential  findings  and  conclusions  on
which the award is based, including the calculation of any damages awarded. The decision or award rendered by
the arbitrators shall be final and non-appealable, and judgment may be entered upon it in any court of competent
jurisdiction. Any disputing Party may apply for interim injunctive relief with the arbitrators until the arbitration
award  is  rendered  or  the  controversy  is  otherwise  resolved.  The  arbitrators  shall  be  authorized  to  award
compensatory  damages,  but  shall  not  be  authorized  (i)  to  award  non-economic  damages,  (ii)  to  award  punitive
damages or any other damages expressly excluded under this Agreement, or (iii) to reform, modify or materially
change  this  Agreement  or  any  other  agreements  contemplated  hereunder;  provided,  however,  that  the  damage
limitations  described  in  subsections  (i)  and  (ii)  of  this  sentence  will  not  apply  if  such  damages  are  statutorily
imposed.

Costs. Each Party shall bear its own attorneys’ fees, costs, and disbursements arising out of the arbitration,
(c)
and shall pay an equal share of the fees and costs of the arbitrators; provided, however, that the arbitrators shall be
authorized  to  determine  whether  a  Party  is  the  prevailing  party,  and  if  so,  to  award  to  that  prevailing  party
reimbursement  for  any  or  all  of  its  reasonable  attorneys’  fees,  costs  and  disbursements  (including,  for  example,
expert witness fees and expenses, photocopy charges, travel expenses, etc.), and/or the fees and costs of the ICC
and the arbitrators.

(iii)

Court Actions. Nothing  contained  in  this  Agreement  shall  deny  any  Party  the  right  to  seek,  upon  good
cause, injunctive or other equitable relief from a court of competent jurisdiction in the context of an emergency or prospective
irreparable harm, and such an action may be filed and maintained notwithstanding any ongoing dispute resolution discussions or
arbitration proceedings.

10.7 Notices. Any notice required or permitted pursuant to this Agreement shall be given in writing and shall be given

either personally or by sending it by next-day or second-

30

day courier service, fax, electronic mail or similar means to the address of the relevant Party as shown on Schedule A (or at such
other  address  as  such  Party  may  designate  by  fifteen  (15)  days’  advance  written  notice  to  the  other  Parties  to  this  Agreement
given in accordance with this Section). Where a notice is sent by next-day or second-day courier service, service of the notice
shall  be  deemed  to  be  effected  by  properly  addressing,  pre-paying  and  sending  by  next-day  or  second-day  service  through  an
internationally-recognized courier a letter containing the notice, with a written confirmation of delivery, and to have been effected
at the earlier of (i) delivery (or when delivery is refused) and (ii) expiration of two (2) Business Days after the letter containing
the same is sent as aforesaid. Where a notice is sent by electronic mail, service of the notice shall be deemed to be effected by
properly addressing, and sending such notice through a transmitting organization, with a written confirmation of delivery, and to
have been effected on the day the same is sent as aforesaid, if such day is a Business Day and if sent during normal business
hours of the recipient, otherwise the next Business Day. Notwithstanding the foregoing, to the extent a “with a copy to” address is
designated,  notice  must  also  be  given  to  such  address  in  the  manner  above  for  such  notice,  request,  consent  or  other
communication hereunder to be effective.

10.8 Rights Cumulative; Specific Performance. Each and all of the various rights, powers and remedies of a Party
hereto will be considered to be cumulative with and in addition to any other rights, powers and remedies which such Party may
have at Law or in equity in the event of the breach of any of the terms of this Agreement. The exercise or partial exercise of any
right, power or remedy will neither constitute the exclusive election thereof nor the waiver of any other right, power or remedy
available to such Party. Without limiting the foregoing, the Parties hereto acknowledge and agree irreparable harm may occur for
which  money  damages  would  not  be  an  adequate  remedy  in  the  event  that  any  of  the  provisions  of  this  Agreement  were  not
performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Parties shall be
entitled  to  injunctive  relief  to  prevent  breaches  of  this  Agreement  and  to  enforce  specifically  the  terms  and  provisions  of  this
Agreement.

10.9

Severability.  In  case  any  provision  of  the  Agreement  shall  be  invalid,  illegal  or  unenforceable,  the  validity,
legality  and  enforceability  of  the  remaining  provisions  shall  not  in  any  way  be  affected  or  impaired  thereby.  If,  however,  any
provision of this Agreement shall be invalid, illegal, or unenforceable under any such applicable Law in any jurisdiction, it shall,
as to such jurisdiction, be deemed modified to conform to the minimum requirements of such Law, or, if for any reason it is not
deemed so modified, it shall be invalid, illegal, or unenforceable only to the extent of such invalidity, illegality, or limitation on
enforceability  without  affecting  the  remaining  provisions  of  this  Agreement,  or  the  validity,  legality,  or  enforceability  of  such
provision in any other jurisdiction.

10.10 Amendments and Waivers. Any provision in this Agreement may be amended and the observance thereof may
be waived (either generally or in a particular instance and either retroactively or prospectively), only by the written consent of (i)
the Company; (ii) Overland; and (iii) Allogene. Notwithstanding the foregoing, any Party hereunder may waive any of its rights
hereunder without obtaining the consent of any other Party. Any amendment or waiver effected in accordance with this Section
shall be binding upon all the Parties hereto.

31

10.11 No Waiver. Failure to insist upon strict compliance with any of the terms, covenants, or conditions hereof will not
be deemed a waiver of such term, covenant, or condition, nor will any waiver or relinquishment of, or failure to insist upon strict
compliance with, any right, power or remedy hereunder at any one or more times be deemed a waiver or relinquishment of such
right, power or remedy at any other time or times.

10.12 Delays or Omissions. No delay or omission to exercise any right, power or remedy accruing to any Party under
this  Agreement,  upon  any  breach  or  default  of  any  other  Party  under  this  Agreement,  shall  impair  any  such  right,  power  or
remedy of such non-breaching or non-defaulting Party nor shall it be construed to be a waiver of any such breach or default, or an
acquiescence therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or
default  be  deemed  a  waiver  of  any  other  breach  or  default  theretofore  or  thereafter  occurring.  Any  waiver,  permit,  consent  or
approval of any kind or character on the part of any Party of any breach or default under this Agreement, or any waiver on the
part of any Party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent
specifically set forth in such writing.

10.13 No  Presumption.  The  Parties  acknowledge  that  any  applicable  Law  that  would  require  interpretation  of  any
claimed ambiguities in this Agreement against the Party that drafted it has no application and is expressly waived. If any claim is
made by a Party relating to any conflict, omission or ambiguity in the provisions of this Agreement, no presumption or burden of
proof or persuasion will be implied because this Agreement was prepared by or at the request of any Party or its counsel.

10.14 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same instrument. E-mailed copies of signatures shall be deemed to
be originals for purposes of the effectiveness of this Agreement.

10.15 Entire Agreement. This Agreement (including the Exhibits hereto) constitutes the full and entire understanding
and agreement among the Parties with regard to the subjects hereof, and supersedes all other agreements between or among any
of the Parties with respect to the subject matter hereof.

10.16 Agreement Controlling. In the event of any conflict or inconsistency between any of the terms of this Agreement
and any of the terms of the Memorandum and Articles or any of the Charter Documents for any of the Group Companies other
than the Company, or in the event of any dispute related to any such Charter Document, the terms of this Agreement shall prevail
in all respects, the Parties shall give full effect to and act in accordance with the provisions of this Agreement over the provisions
of the Charter Documents, and the Parties hereto shall exercise all voting and other rights and powers (including to procure any
required alteration to such Charter Documents to resolve such conflict or inconsistency) to make the provisions of this Agreement
effective, and not to take any actions that impair any provisions in this Agreement.

10.17 Aggregation of Shares. All Shares held or acquired by any Affiliates shall be aggregated together for the purpose

of determining the availability of any rights of any Shareholder, under this Agreement.

32

10.18 Use  of  English  Language.  This  Agreement  has  been  executed  and  delivered  in  the  English  language.  Any
translation of this Agreement into another language shall have no interpretive effect. All documents or notices to be delivered
pursuant to or in connection with this Agreement shall be in the English language or, if any such document or notice is not in the
English  language,  accompanied  by  an  English  translation  thereof,  and  the  English  language  version  of  any  such  document  or
notice shall control for purposes thereof.

10.19 Effective Date. This Agreement shall only take effect and become binding on and enforceable against the Parties

subject to and upon the Closing (as defined in the Share Purchase Agreement) (the “Effective Date”).
