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.

In collaboration with Servier, we are developing UCART19 and ALLO-501, chimeric antigen receptor (CAR) T cell product candidates targeting
CD19. Servier is sponsoring two Phase 1 clinical trials of UCART19 in patients with relapsed/refractory (R/R) B-cell precursor acute lymphoblastic leukemia
(ALL), one for adult patients (the CALM trial) and one for pediatric patients (the PALL trial). In January 2019, the U.S. Food and Drug Administration
(FDA) cleared our investigational new drug application (IND) for ALLO-501, and we plan to initiate a Phase 1/2 clinical trial (the ALPHA trial) in the first
half of 2019 for the treatment of R/R non-Hodgkin lymphoma (NHL). In addition, we have a deep pipeline of allogeneic CAR T cell product candidates
targeting multiple promising antigens in a host of hematological malignancies and solid tumors. For example, we plan to submit an IND and initiate a Phase 1
clinical trial in 2019 for ALLO-715, an allogeneic CAR T cell product candidate targeting B-cell maturation antigen (BCMA) for the treatment of R/R
multiple myeloma. 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 these potentially curative therapies for patients with aggressive cancer.

CAR T cell therapy, a form of cancer immunotherapy, has recently emerged as a revolutionary and potentially curative therapy for patients with
hematologic cancers, including refractory cancers. In 2017, 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 FDA for the treatment of R/R B-cell precursor 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.

Our Approach

Our allogeneic T cell development strategy has four key pillars: (1) developing 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 in patients, (3) building a leading manufacturing platform 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. 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. Finally, we plan to leverage next generation technologies to improve the functionality of our product candidates and to develop
more potent product candidates. 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, UCART19 and ALLO-501, 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, other blood cancers and solid tumors. Our pipeline is
represented in the diagram below.

1 Phase 3 may not be required if Phase 2 is registrational.
2 Servier holds ex-US commercial rights.
3 ALLO-647 intended to enable expansion and persistence of allogeneic CAR T product candidates.

Our lead product candidates include:

•

•

•

UCART19. In 2016, our collaboration partner, Servier, initiated the CALM trial for adult patients with R/R ALL and the PALL trial for pediatric
patients with R/R ALL. In December 2018, interim results from 21 patients in the CALM and PALL clinical trials were presented at the 60th
American Society of Hematology (ASH) Annual Meeting. As of October 23, 2018, 67% (14/21) of patients achieved complete remission (CR) or
complete remission with incomplete blood recovery (CRi). Eighty-two percent (14/17) of patients who received a lymphodepletion regimen
consisting of fludarabine, cyclophosphamide and an anti-CD52 monoclonal antibody (FCA) achieved a CR/CRi. In the four patients who
received fludarabine and cyclophosphamide (FC) only, there was no evidence of UCART19 cell expansion and no responses were observed. We
believe the interim data of UCART19 suggest an anti-CD52 antibody is an important addition to the lymphodepletion regimen for allogeneic
CAR T cell expansion, and we are progressing the development of our own anti-CD52 antibody, ALLO-647, as described below. The most
common adverse events were related to cytokine release syndrome (CRS) and were generally manageable. Two mild (Grade 1) GvHD cases in
the skin were observed and resolved. We expect UCART19 to be advanced to potential registrational trials in 2020. See “—Product Pipeline and
Development Strategy—UCART19—Pooled CALM and PALL Clinical Findings—Interim Safety” for more information regarding adverse
events.

ALLO-501. In January 2019, the FDA cleared our IND for the ALPHA trial of ALLO-501, and we plan to initiate the ALPHA trial in the first
half of 2019 for the treatment of patients with R/R NHL. The Phase 1 portion of the ALPHA trial is designed to assess the safety and tolerability
at increasing dose levels of ALLO-501 in the most common NHL subtypes of R/R large B-cell lymphoma, including diffuse large B-cell
lymphoma (DLBCL), or follicular lymphoma (FL). Assuming positive Phase 1 data, we plan to introduce our second-generation version of
ALLO-501 in the Phase 2 portion of the trial. We have removed rituximab recognition domains in the second generation of ALLO-501, which we
believe will potentially facilitate treatment of patients who were previously treated with rituximab.

ALLO-715. We plan to submit an IND and initiate a Phase 1 clinical trial in 2019 for ALLO-715, targeting BCMA for the treatment of patients
with R/R multiple myeloma. Several clinical studies of third-party autologous CAR T cell therapies targeting BCMA have produced promising
results in this indication.

•

ALLO-647. 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. 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 plan to utilize ALLO-647 in the ALPHA trial and, subject to regulatory acceptance, in the clinical
trial for ALLO-715.

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 UCART19 and ALLO-501, and we hold the
commercial rights to these product candidates in the United States. Under our collaboration with Servier, we also have an exclusive option to obtain the same
rights to additional product candidates targeting one additional cancer antigen. 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 our collaboration with Servier. 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.

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 first mover advantage 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, such as UCART19 and ALLO-501, is the next
frontier in delivering potentially curative therapies against B-cell lymphomas and leukemias, including NHL and ALL. We plan to support
Servier in advancing the CALM and PALL trials in ALL and initiating potential registrational trials for UCART19 in 2020 after completion of the
CALM and PALL trials. We also plan to initiate the ALPHA trial in the first half of 2019 for ALLO-501 in R/R NHL. We believe having the first
anti-CD19 allogeneic CAR T cell product candidate in the clinic gives us a first mover advantage in efforts to obtain approval of and
commercialize anti-CD19 allogeneic CAR T cell product candidates in B-cell lymphoma and leukemia indications.

Expand our leadership position within hematologic indications. In addition to UCART19 and ALLO-501, we plan to advance our near-term
pipeline against additional hematological targets where there remains a high unmet need. For example, we are developing ALLO-715, an
allogeneic CAR T cell product candidate targeting BCMA. We believe BCMA is a promising target, as early results from clinical trials of third-
party autologous CAR T cell therapeutic candidates targeting BCMA have been compelling. We plan to submit an IND and initiate a Phase 1
clinical trial of ALLO-715 for the treatment of patients with R/R multiple myeloma in 2019. In addition to advancing UCART19, ALLO-501 and
ALLO-715, we plan to develop additional allogeneic T cell product candidates targeting other antigens found on hematologic malignancies,
including ALLO-819 targeting FLT3 for the treatment of acute myeloid leukemia (AML).

5

 
 
 
 
•

•

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 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.

Leverage next generation technologies to advance our platform and expand into solid tumor indications with high unmet need. We have a
broad portfolio of solid tumor targets, including CD70 for the treatment of renal cell cancer and DLL3 for the treatment of small cell lung cancer
and other aggressive neuroendocrine tumors. We 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 are exploring ways to improve the functionality of our product candidates,
such as modulating cytokines to augment expansion, persistence and trafficking of allogeneic T cells. We are also exploring gene-editing
technologies to allow site-specific integration of CARs and investigating the utility of a single cell product targeting multiple antigens. 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.

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.

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 recognize and destroy cancer cells in a more 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 UCART19, ALLO-501 and ALLO-715 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.

6

 
 
 
 
 
 
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. UCART19 and ALLO-501 possess rituximab recognition domains in a separate polypeptide termed RQR8 that
is co-expressed with the CAR. The modification in ALLO-715 is designed to increase the efficiency of rituximab-mediated cell killing.

The figure below shows the constructs that support our three lead programs: UCART19, ALLO-501 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 healthy donor T cells.

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.

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.

7

 
 
 
 
 
 
 
•

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. 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 with two key differences: (1) allogeneic T cells are derived
from healthy donors, not cancer patients, and (2) allogeneic T cells must be 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 as well as enable treatment with multiple different
engineered allogeneic T cell products directed to different cancer targets in a patient.

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 prescription. This would represent a significant reduction in patient wait time, potentially 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.

8

 
 
 
 
 
 
•

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.

9

 
 
 
 
 
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 also 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.

Step 2. Gene Editing

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 enable us to perform targeted genome modifications such as sequence insertion, deletion, repair and replacement in living cells.

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, which is performed for UCART19, ALLO-501, and ALLO-715, 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.

10

 
 
 
 
 
•

•

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 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 plan to use ALLO-647 in our ALPHA trial and in our clinical
trial of ALLO-715.

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 10
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 can completely
inactivate 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 will be securely stored and then shipped to oncology
centers as needed.

11

 
 
 
 
 
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.

In the near term, we are progressing multiple product candidates directed at promising targets for blood cancers, including ALL, NHL, multiple

myeloma and AML. We are also conducting earlier-stage research programs focused on targets associated with solid tumors, such as renal cell carcinoma,
small cell lung cancer and other common epithelial cancers.

Our product pipeline is represented in the diagram below:

1 Phase 3 may not be required if Phase 2 is registrational.
2 Servier holds ex-US commercial rights.
3 ALLO-647 intended to enable expansion and persistence of allogeneic CAR T product candidates.

12

 
 
 
 
 
In addition to the allogeneic CAR T cell product candidates we are developing for the treatment of blood cancers and solid tumors, 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.

UCART19

We, in partnership with Servier, are developing UCART19 to be a potential first-in-class allogeneic CAR T cell product candidate for the treatment of

pediatric and adult patients with R/R CD19 positive B-cell ALL. There are currently two ongoing Phase 1 clinical trials in adult and pediatric R/R ALL.
Servier is the sponsor of the UCART19 clinical trials and is also responsible for manufacturing UCART19.  Servier is experiencing UCART19 supply issues
relating to the manufacturing of UCART19, and, as a result, while the clinical trials of UCART19 remain active, they are not recruiting new patients. We
currently expect UCART19 to be advanced to potential registrational trials in 2020.

UCART19 targets CD19, an antigen expressed on the surface of B cells, including malignant B cells. In addition to these indications, CD19 targeting

CAR T therapies have shown preliminary efficacy in chronic lymphocytic leukemia, mantle cell lymphoma and low-grade NHLs, such as FL or marginal
zone lymphoma.

13

 
 
 
UCART19 is 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 are engineered to express a small protein on the cell surface called RQR8,
which consists of two rituximab recognition domains. This allows for recognition and elimination of cells in the event that silencing of CAR activity is
desired. The figure bellow depicts the construct of UCART19.

Target Indication: Acute Lymphoblastic Leukemia (ALL)

ALL is characterized by the proliferation of immature lymphocytes in the bone marrow. Approximately 5,960 new cases and 1,470 deaths in the
United States were estimated in 2018, according to the U.S. SEER database. Approximately 80% of cases of ALL are B-cell ALL, which we plan to address
with UCART19.

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, and use of tyrosine kinase inhibitors for Philadelphia chromosome–positive ALL. 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.  

Clinical Data

UCART19 is being studied in two ongoing Phase 1 clinical trials, CALM and PALL, sponsored and conducted by Servier, our collaboration partner.

Initiated in 2016, CALM is an ongoing Phase 1, open-label, dose-escalation clinical trial in adult patients with R/R ALL to evaluate safety, anti-leukemic
activity, and determine the maximum tolerated dose (MTD). Post-therapy allo-SCT was allowed at the discretion of the investigator. Initiated in 2016, PALL
is an ongoing Phase 1, open-label, clinical trial in pediatric R/R ALL patients to evaluate safety and anti-leukemic activity.

14

 
 
 
Prior to the initiation of CALM and PALL, UCART19 was administered to three patients with CD19 positive B-cell ALL (two children and one adult)
under a compassionate use license granted by the Medicines and Healthcare Products Regulatory Agency in the United Kingdom. The patients had previously
failed multiple lines of prior treatment. UCART19 for these patients was manufactured at an academic site, the University College London. The two pediatric
patients achieved a CR and received allo-SCT, and the one adult died within the first month following UCART19 infusion due to disease progression.

Pooled CALM and PALL Interim Clinical Findings

In December 2018, interim results from 21 patients in the CALM and PALL clinical trials were presented at the 60th ASH Annual Meeting. As of the
October 23, 2018 data cutoff, 21 patients enrolled had been treated in the CALM and PALL clinical trials. In the CALM trial, six patients were treated at the
first dose level of 6 × 106 total cells (approximately 105 cells per kilogram) and six patients were treated at the second dose level with 8 × 107 total cells
(approximately 106 cells per kilogram). Treatment at the third and final dose level of 1.8 to 2.4 × 108 total cells is ongoing. In the PALL trial, all seven of the
patients enrolled had been treated at a weight-banded cell dose equivalent to 1.1 to 2.3 × 106 cells/kg. Patient characteristics are presented below.

The most common UCART19 related adverse event was CRS, reported in 19 patients. Grade 3 or 4 CRS was observed in three patients. Six patients
developed prolonged cytopenia, defined as persistent Grade 4 neutropenia and/or thombocytopenia beyond day 42 after UCART19 infusion. Seven patients
experienced mild, or Grade 1, neurotoxicity events and one patient experienced Grade 2 neurotoxicity events. Viral infections was attributed to
lymphodepletion and/or UCART19. Two patients experienced Grade 1 GvHD adverse event of the skin, which resolved with steroids.

There were no new treatment-related deaths from the previous interim data report presented at the 23rd European Hematology Association Annual

Congress in June 2018. As previously presented, there were two treatment-related deaths in the CALM study, one at day 15 post infusion as a result of Grade
4 CRS associated with Grade 5 neutropenic sepsis and one at day 82 post infusion in the post allogeneic stem-cell transplant setting. Grade 5 adverse events
have been reported in other autologous anti-CD19 CAR T cell therapy trials in part due to advanced stage of disease and accompanying confounding
conditions.

Eight deaths have also been reported that were not attributed to UCART19. Six patients died from progressive disease and two patients from allo-SCT

related complications. Transplant related mortality occurs in approximately 20-30% of patients following allo-SCT.

Interim Efficacy

As of October 2018, 67% (14/21) of patients achieved a CR/CRi. Eighty-two percent (14/17) of patients who received a lymphodepletion regimen
consisting of fludarabine, cyclophosphamide and an anti-CD52 monoclonal antibody (FCA) achieved a CR/CRi. In the four patients who received fludarabine
and cyclophosphamide (FC) only, there was no evidence of UCART19 cell expansion and no response. Seventy-one percent (10/14) of patients achieved
MRD- CR. Three patients received a second dose of UCART19, two under compassionate use (as a deviation from the clinical trial protocol) and one under
amended protocol, and two achieved cell expansion and MRD- CR. MRD- CR occurs when a patient achieves a CR and there is no evidence of ALL cells in
the marrow when using sensitive tests such as polymerase chain reaction or flow cytometry. CR or CRi rates are the typical regulatory standard, but studies in
both children and adults with ALL have demonstrated a strong correlation between minimal residual disease (MRD+) and risks for relapse.

We believe these data suggest an anti-CD52 antibody is an important addition to the lymphodepletion regimen for allogeneic CAR T cell
expansion.  We therefore believe that an anti-CD52 antibody is important to the success of our allogeneic CAR T platform. Going forward, the PALL and
CALM trials will require the use of an anti-CD52 monoclonal antibody in the lymphodepletion regimen.

CAR T cell expansion was detected in blood from day 7 after UCART19 infusion, reaching the peak expansion between day 10 and day 17. One

patient treated in the CALM trial at the second dose level showed the highest peak linked to a long persistence up to 4 months.

16

 
The four patients on the FC regimen showed no evidence of CAR T cell expansion. A similar lack of CAR T cell expansion was seen in two out of 10

patients on the FCA regimen. The following table illustrates response, duration of remission and re-dosing of UCART19 in the CALM and PALL trial as of
the October 2018 data cutoff.

Development Plan

We, in partnership with Servier, plan to complete the third dose level of UCART19 in CALM in order to determine the recommended Phase 2 dose

level, and then expand the enrollment to gain additional patient experience on the optimal lymphodepletion regimen, specifically testing the benefits of anti-
CD52 monoclonal antibody, alemtuzumab or ALLO-647. We expect UCART19 to be advanced to potential registrational trials, CALM2 and PALL2, in 2020.

CALM2 will be designed to evaluate the efficacy of UCART19 in an open-label, Phase 2, international, non-comparative, two-stage, pivotal,

multicenter, single-arm clinical trial in adult patients with R/R ALL who have exhausted available treatment options. The dose will be a flat dose based on the
recommended Phase 2 dose identified in Phase 1. The primary efficacy endpoint will be overall complete remission rate within three months of UCART19
infusion. Up to 63 patients are expected to be enrolled. Redosing will be allowed in case of relapse within a three month period after the first infusion.

PALL2 will be designed as an open-label, Phase 2, international, non-comparative, two-stage, pivotal clinical trial of pediatric patients with R/R ALL
range from birth to 18 years at time of initial diagnosis. The dose of UCART19 will depend on the actual weight at the time of infusion. The primary efficacy
endpoint will be molecular response rate according to MRD result within two months of UCART19 infusion. Up to 49 patients are expected to be enrolled.
Patients will be monitored for 12 months after infusion whether or not they have received an allo-SCT. Redosing will be allowed in case of relapse within the
three-month period after the first infusion. Servier submitted a pediatric investigation plan to the European Medicines Agency (EMA) in March 2018. We
expect Servier to submit a revised pediatric investigation plan to the EMA in 2019, with regulatory feedback expected over several months after submission.

In the CALM and PALL trials, Servier uses alemtuzumab, a commercially available monoclonal antibody that binds CD52, for the purpose of
lymphodepletion. To secure our own readily available source of anti-CD52 antibody, we are developing our own monoclonal anti-CD52 antibody, ALLO-
647.

ALLO-501

ALLO-501 is our other allogeneic CAR T cell product candidate targeting CD19. We plan to initiate the ALPHA trial, a Phase 1/2 clinical trial for the
treatment of R/R NHL in the first half of 2019. ALLO-501 is jointly developed by us and Servier. We will be the sponsor of the ALLO-501 program and lead
the clinical development program.

17

 
The first and current version of 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. Clinical supply for ALLO-501 trials will be manufactured in the United States using a CMO.

Target Indication: Non-Hodgkin Lymphoma (NHL)

NHL is a hematologic cancer originating from malignant lymphocytes. It is the most common hematological malignancy in the United States, with

74,680 new cases and 19,910 deaths were estimated to be diagnosed in 2018, according to the U.S. SEER database. 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 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 second line 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.

18

 
 
Clinical Development Plan

The ALPHA trial is an open-label, Phase 1/2, single arm, multicenter clinical trial evaluating the safety and efficacy of ALLO-501 in 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. The Phase 1 portion of the trial will be a dose-escalation study for ALLO-501 with three separate dose cohorts, from 40 × 106 to
360 × 106 total cells. A dose of ALLO-501 will be selected as the recommended Phase 2 dose. Prior to ALLO-501 treatment, all patients are expected to
undergo lymphodepletion with a regimen of fludarabine, cyclophosphamide and ALLO-647.

Assuming positive Phase 1 data, we plan to introduce our second-generation of ALLO-501, as discussed below, in the Phase 2 portion of the trial. We

believe the second-generation ALLO-501 will have the potential to facilitate treatment of patients who were previously treated with rituximab.

Approximately 24 patients are expected to be evaluated in Phase 1 and approximately 70 patients are expected to be evaluated in Phase 2. All patients

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

Next Generation

We have created a second version of ALLO-501. The first and current version of ALLO-501 co-expresses a small protein on the cell surface called

RQR8, which consists of two rituximab recognition domains. This allows for removal of the CAR T by rituximab. Since prior treatment with rituximab,
depending on the lag time between the rituximab administration and planned ALLO-501 infusion, may interfere with ALLO-501, we have removed RQR8 in
this second version of ALLO-501, as illustrated in the figure below. The second version of ALLO-501 manufactured from several donors under non-cGMP
conditions has been compared to the current version of ALLO-501 in vitro. In this study, we found that both first and second versions of ALLO-501 exhibited
similar characteristics and killing activity.

ALLO-715

ALLO-715 is an allogeneic CAR T cell product candidate targeting BCMA. 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). ALLO-715 will initially be evaluated
for the treatment of adult patients with R/R multiple myeloma. We plan to submit an IND and initiate a Phase 1 clinical trial for ALLO-715 in 2019.

19

 
 
 
 
 
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, has been incorporated in between the scFv
and the linker domain. We have completed the lead candidate selection and manufacturing under cGMP conditions is in process to enable IND submission.
The figure bellow depicts the construct of ALLO-715.

Target Indication: Multiple Myeloma

Multiple myeloma is a hematological malignancy that is characterized by uncontrolled expansion of bone marrow plasma cells. There was an
estimated 30,770 new cases of multiple myeloma and 12,770 deaths from multiple myeloma in 2018 in the United States according to the U.S. SEER
database. 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. In the past five years, several new drugs with novel
mechanisms (Darzalex, Empliciti, Farydak) 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 complete response to Darzalex.
Median survival in such patients was just 17.5 months. Trials of autologous CAR T cell therapies such as bb2121, currently being developed by bluebird bio,
Inc. (bluebird) in partnership with Celgene Corporation, have shown early promise in multiple myeloma with complete response rates of 50% at doses greater
than 150 × 106 CAR T cells.

Clinical Development Plan

We plan to submit an IND and initiate a Phase 1 clinical trial of ALLO-715 in 2019. The trial is expected to be an open label, multi-dose, multi center,
dose escalation, safety, pharmacokinetic and pharmacodynamic clinical trial of ALLO-715 in adult patients with R/R multiple myeloma, who have progressed
on at least three lines of prior therapy. The primary goal will be to assess safety and tolerability at increasing dose levels of ALLO-715 in successive cohorts
of patients in order to estimate the MTD and the recommended Phase 2 dose of ALLO-715. Prior to ALLO-715 treatment, all patients are expected to
undergo lymphodepletion with a regimen of fludarabine, cyclophosphamide and ALLO-647.

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), CD70 for the treatment of renal cell carcinoma, and DLL3 for the treatment of small cell lung cancer (SCLC).

•

•

•

Acute Myeloid Leukemia and ALLO-819. AML is a high unmet medical need with few treatment options. It is a cancer of bone marrow stem
cells and is the most common type of leukemia in adults. SEER estimated 19,520 new diagnoses and 10,670 deaths in the United States in 2018.
Patients have a poor prognosis despite improvements in chemotherapy regimens and supportive care. 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 advancing an IND-enabling data set for ALLO-
819.

Renal Cell Carcinoma and CD70. Analysis using proteomic and immunohistochemistry techniques have demonstrated a high level of CD70
expression in clear cell renal cell carcinoma (ccRCC) cell lines and in more than 80% of human ccRCC tumor samples. ccRCC is the most
common subtype of renal cancer. Approximately 65,000 new cases of renal cell carcinoma are diagnosed per year in the United States and 15,000
deaths were estimated in 2018, according to SEER. Average duration of disease control is eight to nine months in first-line and five to six months
in second-line, with the five year survival rate for metastatic disease of only 11.6%, and median survival of high risk group at 5.9 months. We are
in the final stages of testing and refining constructs and selecting an anti-CD70 CAR T candidate to progress to IND-enabling studies.

Small Cell Lung Cancer and DLL3. DLL3 is a target which is being pursued for SCLC using ADCs, bi-specifics and autologous CAR T
therapies. According to SEER, there was approximately 234,000 new cases of lung cancer in the United States in 2018, and according to the
American Cancer Society, 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. Recently, 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 eight months.
We believe an allogeneic anti-DLL3 CAR T cell product candidate could be used alone or in combination with PD-1/PD-L1 therapy. We are
currently testing and refining constructs for an anti-DLL3 CAR T candidate, and following completion we plan to progress to IND-enabling
studies.

We also plan to enhance our platform using next-generation technologies such as cytokine signal modulation, switch technologies, including small-

molecule induced off-switch, site-specific integration and multi-specific CARs.

•

•

•

Cytokine Signal Modulation. Expressing cytokines from CAR T cells or mimicking cytokine activation signaling could enhance the proliferative
potential, migratory behavior, and killing activity of engineered CAR T cells. Such modulation may enhance the anti-tumor activity of CAR T
cells. We are currently investigating multiple construct designs to induce cytokine signaling in CAR T cells.

Switch Technology. In addition to the CD20 epitope engineered off-switch, such as RQR8 that sensitizes cells to rituximab, we are investigating
the use of small molecules that dimerize death-inducing proteins to eliminate CAR T cells in the event that CAR T cell activity is no longer
needed or should be shut off for safety reasons.

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.

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. We plan to continue to

invest in process science, product characterization and manufacturing to continuously improve our production and supply chain capabilities over time.

21

 
 
 
 
 
 
 
 
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 current good manufacturing practices (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.

Servier is responsible for UCART19 manufacturing and is working with a CMO in Europe to provide clinical supply for the CALM and PALL clinical

trials. The first and current version of ALLO-501 is identical in molecular design to UCART19, but is produced using a modified manufacturing process,
optimized by us. ALLO-501 and ALLO-715 will be manufactured in the United States by a CMO, and we will manage all other aspects of the supply,
including planning, CMO oversight, disposition and distribution logistics. We will similarly develop, and manufacture all of our other product candidates.

The CMO that is manufacturing the clinical supply of ALLO-501 and ALLO-715 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. 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 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

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) and an Exclusive License and Collaboration Agreement with Servier (the
Servier Agreement). For additional information regarding our significant agreements, see Note 7 to our financial statements and Item 9B “Other Information”,
each 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 most advanced product candidate,

UCART19, our other product candidates, ALLO-647, ALLO-501 and ALLO-715, future 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.

22

 
 
 
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, and have U.S. rights to these patents for CD19. 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, UCART19, ALLO-501 and ALLO-715, as well as our other research-stage

candidates. With respect to UCART19 and ALLO-501, 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 UCART19 and ALLO-501. 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

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.

Novartis and Kite were the first to achieve FDA approval for autologous T cell therapies. In August 2017, Novartis obtained FDA approval to
commercialize Kymriah, 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 DLBCL. In October 2017, Kite obtained FDA approval to commercialize Yescarta, the first CAR T cell product
candidate for the treatment of adult patients with R/R large B-cell lymphoma.

Due to the promising therapeutic effect of T cell therapies in clinical trials, we anticipate increasing competition from existing and new companies

developing these therapies, as well as in the development of allogeneic T cell therapies.

Potential cell therapy competitors include:

•

•

Allogeneic T cell therapy competition: Atara Biotherapeutics, Inc., Celyad S.A., CRISPR Therapeutics AG, Fate Therapeutics Inc., Intellia
Therapeutics, Inc., Gilead (acquired Kite), Poseida Therapeutics, Inc., Precision Biosciences, Inc. and Sangamo Therapeutics, Inc. Additionally,
Cellectis has several fully-owned allogeneic CAR programs that will compete with programs that fall outside our agreement with Cellectis.

Autologous T cell therapy competition: Adaptimmune Therapeutics PLC, Amgen Inc., Autolus Therapeutics plc, bluebird, Gilead, Novartis,
Celgene (acquired Juno), Tmunity Therapeutics, Inc. and Unum Therapeutics Inc.

23

 
 
 
Competition will also arise from non-cell based immune and other pursued by small-cap biotechnology and large-cap pharmaceutical companies

including Amgen Inc., AstraZeneca plc, Bristol-Myers Squibb Company, Incyte Corporation, Merck & Co., Inc., and F. Hoffmann-La Roche AG. For
instance, we may experience competition from companies, such as Amgen Inc., Regeneron Pharmaceuticals, Inc., Xencor Inc., MacroGenics, Inc.,
GlaxoSmithKline plc and F. Hoffmann-La Roche AG, that are pursuing bispecific antibodies, which 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 Amgen Inc., GlaxoSmithKline plc and Seattle Genetics, 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, and convenience.

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

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;

24

 
 
 
•

•

•

•

•

•

•

•

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 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.

25

 
 
 
 
 
 
 
 
 
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.

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

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.

26

 
 
 
 
Within 60 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 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. Unless otherwise required by
regulation, PREA does not apply to any product for an indication for which orphan designation has been granted. However, if only one indication for a
product has orphan designation, a pediatric assessment may still be required for any applications to market that same product for the non-orphan indication(s).

27

 
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.

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.

28

 
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.

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, 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.

29

 
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 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.

30

 
 
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. Several pharmaceutical and other healthcare companies are being
investigated or, in the past, have been prosecuted under these laws for allegedly providing free product to customers with the expectation that the customers
would bill federal programs for the product. Other companies have been prosecuted 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 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.

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 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 penalties, including without limitation, civil, criminal and administrative penalties, damages, fines, disgorgement,
imprisonment, exclusion from participation in government programs, such as Medicare and Medicaid, injunctions, private “qui tam” actions brought by
individual whistleblowers in the name of the government, or 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.

31

 
 
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 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 that began in 2011;

increased the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program, retroactive to January 1, 2010, 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;

32

 
 
 
 
•

•

•

•

•

•

•

•

•

•

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 Foreign Corrupt Practices Act (FCPA) and the Anti-Kickback Statute, 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;

established a Center for Medicare and Medicaid Innovation at CMS to test innovative payment and service delivery models to lower Medicare
and Medicaid spending; and

created a licensure framework for follow on biologic products.

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

the Affordable Care Act. Since January 2017, the current U.S. President has signed two 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).

On January 22, 2018, the current U.S. President signed a continuing resolution on appropriations for fiscal year 2018 that delayed the implementation
of certain Affordable Care Act-mandated fees, including the so-called “Cadillac” tax on certain high cost employer-sponsored insurance plans, the annual fee
imposed on certain health insurance providers based on market share, and the medical device excise tax on non-exempt medical devices. 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”. Congress is continuing to consider legislation that would alter other aspects of the Affordable Care Act.
The ultimate content, timing or effect of any healthcare reform legislation on the U.S. healthcare industry is unclear. In July 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. While the Texas U.S. District Court Judge, as well as the Trump administration and
CMS, have stated that the ruling will have no immediate effect pending appeal of the decision, it is unclear how this decision, subsequent appeals, and other
efforts to repeal and replace the Affordable Care Act will impact the Affordable Care Act.

We anticipate that the Affordable Care Act, if substantially maintained in its current form, 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.

33

 
 
 
 
 
 
 
 
 
 
 
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 2027 unless additional Congressional action is
taken. In January 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to
several 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 U.S. President’s administration’s budget
proposal for fiscal year 2019 contains further drug price control measures that could be enacted during the 2019 budget process or in other future legislation,
including, for example, measures to permit Medicare Part D plans to negotiate the price of certain drugs under Medicare Part B, to allow some states to
negotiate drug prices under Medicaid, and to eliminate cost sharing for generic drugs for low-income patients. Additionally, the U.S. President’s
administration released a “Blueprint” to lower drug prices and reduce out of pocket costs of drugs that contains additional proposals to increase manufacturer
competition, increase the negotiating power of certain federal healthcare programs, incentivize manufacturers to lower the list price of their products and
reduce the out of pocket costs of drug products paid by consumers. HHS has already started the process of soliciting feedback on some of these measures and,
at the same, is immediately implementing others under its existing authority. For example, in September 2018, CMS announced that it will allow Medicare
Advantage Plans the option to use step therapy for Part B drugs beginning January 1, 2019, and in October 2018, CMS proposed a rule that would require
direct-to-consumer television advertisements of prescription drugs and biological products, for which payment is available through or under Medicare or
Medicaid, to include in the advertisement the Wholesale Acquisition Cost, or list price, of that drug or biological product. On January 31, 2019, the HHS
Office of Inspector General proposed modifications to federal Anti-Kickback Statute safe harbors which, among other things, may affect rebates paid by
manufacturers to Medicare Part D plans, the purpose of which is to further reduce the cost of drug products to consumers. While some of these and other
proposed measures may require authorization through additional legislation to become effective, Congress and the U.S. President’s administration have each
indicated that it will continue to seek new legislative and/or administrative measures to control drug costs. 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.

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
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, 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 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 consumers or households.  When it goes into effect on January 1, 2020, the CCPA will require
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. Legislators have stated that amendments will be proposed to the CCPA before it goes into effect, but it
remains unclear what, if any, modifications will be made to this legislation or how it will be interpreted. As currently written, the CCPA may 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.

Employees

As of March 1, 2019, we had 122 full-time employees. Of these employees, 52 hold Ph.D. or M.D. degrees, and 82 are engaged in research,
development and technical operations. Substantially all of our employees are located in South San Francisco, California. Our employees are not represented
by labor unions or covered by collective bargaining agreements. We consider our relationship with our employees to be good.

Corporate Information

We were incorporated in Delaware in November 2017. Our principal executive offices are located at 210 East Grand Avenue, South San Francisco,

California 94080, and our telephone number is (650) 457-2700. Our corporate website address is www.allogene.com. Information contained on or accessible
through our website is not a part of this report, and the inclusion of our website address in this report is an inactive textual reference only.

Emerging Growth Company

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012. We will remain an emerging growth company

until the earlier of (1) the last day of the fiscal year (a) following the fifth anniversary of the completion of our initial public offering in June 2014, (b) in
which we have total annual gross revenue of at least $1.07 billion, or (c) in which we are deemed to be a large accelerated filer, which means we have been
subject to the reporting requirements of the Exchange Act for twelve calendar months and the market value of our common stock that is held by non-affiliates
exceeded $700.0 million as of the prior June 30th, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior
three-year period. We refer to the Jumpstart Our Business Startups Act of 2012 in this Annual Report as the “JOBS Act,” and references to “emerging growth
company” have the meaning associated with it in the JOBS Act.

Item 1A. Risk Factors

RISK FACTORS

An investment in shares of our common stock involves a high degree of risk. 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.

Risks Related to Our Business and Industry

We have a limited operating history and face significant challenges and expense as we build our capabilities.

We were incorporated in 2017 and acquired certain rights to UCART19 and other allogeneic CAR T cell therapy assets from Pfizer in April 2018. We
have a limited operating history and are subject to the risks inherent in any newly-formed organization, including, among other things, risks that we may not
be able to hire sufficient qualified personnel and establish operating controls and procedures. We are in the process of moving in-house several support
services provided by Pfizer through a Transition Services Agreement (TSA), including certain research and development and general and administrative
services. As we build our own capabilities, we expect to encounter risks and uncertainties frequently experienced by growing companies in new and rapidly
evolving fields, including the risks and uncertainties described herein. Our ability to rely on services from Pfizer is limited for a period of time, and if we are
unable to transition support services in a timely manner, our operating and financial results could differ materially from our expectations, and our business
could suffer.

As a company, we have not progressed any product candidates through clinical development to commercialization. Our collaboration partner, Servier,
conducts the CALM and PALL clinical trials of UCART19, and we cannot be certain that our planned clinical trials of our other product candidates will begin
or be completed on time, if at all.

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 have only recently acquired rights to 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, 2018, we reported a net loss of $211.5 million. As of December 31,
2018, we had an accumulated deficit of $211.5 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, including UCART19, ALLO-
501 and ALLO-715. 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 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;

37

 
 
 
 
•

•

•

•

•

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;

using medicines to manage adverse side effects of our product candidates which may not adequately control the side effects and/or may have 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 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.

The gene-editing technology we use is relatively new, 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 we may not be able do so, 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 and a DNA translocation that may lead to oncogenesis. The gene-editing of our
product candidates may also not be successful in limiting the risk of GvHD or 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.

We are heavily reliant on our partners for access to key gene editing technology for manufacturing our product candidates and for the development of
UCART19 and ALLO-501.

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.

We rely on an agreement with Cellectis for rights to use TALEN and electroporation 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 potentially one additional target. 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 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.

38

 
 
 
 
 
 
In addition, under the Servier Agreement, Servier is responsible for conducting the two clinical trials of UCART19, CALM and PALL. We plan to

support Servier in advancing the CALM and PALL trials, and we expect Servier to support us as we initiate our clinical trial of ALLO-501 for the treatment
of patients with R/R NHL. Other than the agreed-upon global research and development plan for UCART19, we have limited control over the nature or
timing of Servier’s clinical trials and limited visibility into their day-to-day activities. In addition, we rely on Servier for access to data from the UCART19
trials, and as a result at any given time we may not be aware of one or more significant trial developments. If UCART19 encounters safety or efficacy
problems, manufacturing problems, developmental delays, regulatory issues or other problems, our development plans and business would be significantly
harmed. Additionally, other clinical trials being conducted by Servier may at times receive higher priority than research on our programs. Moreover, if Servier
does not provide its share of support for the UCART19 and ALLO-501 clinical trials, our expenses may be greater than we currently expect and we may have
difficulty progressing ALLO-501 in a timely manner.

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 and development 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 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.

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. 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.  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 UCART19 and ALLO-501. If we or Servier are unable to obtain approval for UCART19 and ALLO-
501 and effectively commercialize UCART19 and ALLO-501 for the treatment of patients in approved indications, our business would be significantly
harmed.

Our business and future success depends on our ability to obtain regulatory approval of, and then successfully commercialize, our most advanced
product candidates, UCART19 and ALLO-501. UCART19 is in the early stages of development and has only been administered in a limited number of
patients in Phase 1 clinical trials. The results to date may not predict results for our planned trial or any future studies of UCART19 or any other allogeneic
CAR T product candidate. Because UCART19 and ALLO-501 are among the first allogeneic products to be evaluated in the clinic, the failure of either
product candidate, or the failure of other allogeneic T cell therapies, may significantly influence physicians’ and regulators’ opinions in regards to the
viability of our entire pipeline of allogeneic T cell therapies, particularly if high or uncontrolled rates of GvHD are observed. If significant GvHD events are
observed with the administration of UCART19 or ALLO-501, or if either product candidate is viewed as less safe or effective than autologous therapies, our
ability to develop other allogeneic therapies may be significantly harmed.

We are also dependent on Servier to oversee the manufacturing of UCART19 and conduct the UCART19 trials in a timely and appropriate manner.
Servier is experiencing UCART19 supply issues relating to the manufacturing of UCART19, and, as a result, while the clinical trials of UCART19 remain
active, they are not recruiting new patients. Significant delays in enrollment, due to supply issues or results from the CALM and PALL studies or other
reasons, could affect the progress and success of the CALM and PALL clinical trials, our leadership position in the allogeneic CAR T industry and the ability
to progress additional product candidates.  In addition, we expect Servier to submit a revised pediatric investigation plan for UCART19 to the EMA in 2019.
The EMA could reject the revised pediatric investigation plan, which would affect Servier’s ability to progress the PALL2 clinical trial on the timeframe
currently anticipated or at all.

39

 
All of our product candidates, including UCART19 and ALLO-501, 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 UCART19 and ALLO-501 are our most advanced product candidates, and because our
other product candidates are based on similar technology, if either product candidate 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 and neurotoxicity, 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 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, our allogeneic CAR T cell product candidates may cause unique adverse events related
to the differences between the donor and patients, such as GvHD or infusion reaction.

In the PALL and CALM clinical trials, the most common severe or life threatening adverse events resulted from CRS, prolonged cytopenia and
neutropenic sepsis. Multiple patients have also died in these trials, including two deaths that were attributed to UCART19, as further described in this Annual
Report under the heading “Business—Product Pipeline and Development Strategy—UCART19—Clinical Data”. In the future, patients may experience
additional adverse events related to the lymphodepletion regimen as well as UCART19, some of which may result in death. As we treat more patients with
UCART19 in our clinical trials, new less common side effects may also emerge.

As an anti-CD19 CAR T cell therapy, we expect ALLO-501 to cause similar toxicities as UCART19. Other of our allogeneic CAR T product
candidates may also cause similar or worse toxicities. For instance, because ALLO-715 may require a higher dose than UCART19 and could be used in a
more elderly patient population, it is possible that the risk of GvHD or other adverse events for ALLO-715 could be greater than UCART19.

If unacceptable toxicities arise in the development of our product candidates, we or Servier 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 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, including UCART19, ALLO-501 and ALLO-715, 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.

40

 
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.

Interim “top line” 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 interim “top line” 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 and Servier have published preliminary data from the CALM and PALL clinical trials, 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 UCART19 or our other product candidates.

Preliminary or “top line” 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, 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 an IND to the FDA to initiate a clinical trial of ALLO-715 targeting BCMA for the treatment of patients with R/R multiple
myeloma in 2019, and plan to submit INDs for additional product candidates in the future. However, our timing of filing an IND for ALLO-715 and INDs for
other product candidates is dependent on further pre-clinical and manufacturing success. 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.
Additionally, even if such regulatory authorities agree with the design and implementation of the clinical trials set forth in an IND or clinical trial application,
we cannot guarantee that such regulatory authorities will not change their requirements in the future.

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 these 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 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 contract manufacturing organization (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; 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.

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 safety of patients receiving our product candidates is challenging, which could adversely affect our ability to obtain regulatory approval and
commercialize.

For our clinical trials of UCART19 and ALLO-501 and in our planned clinical trials of other product candidates, we and Servier 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
UCART19 or ALLO-501, 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 UCART19 or ALLO-501 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
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; 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.

In addition, our clinical trials will 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. 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.

Clinical trials are expensive, time-consuming and difficult to design and implement.

Human clinical trials are expensive and difficult to design and implement, in part because they are subject to rigorous regulatory requirements.
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, we expect that they will require extensive research and development and have substantial manufacturing and processing costs. In addition, costs
to treat patients with R/R cancer and to treat potential side effects that may result from our product candidates can be significant. We also have less control of
costs incurred by our development partner, Servier, for the clinical trials of UCART19. Accordingly, our clinical trial costs are likely to be significantly higher
than for more conventional therapeutic technologies or drug products.

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
UCART19, with Servier, and our other 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 and potentially as a first line therapy. 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.

43

 
 
 
 
 
 
 
 
Our projections of both the number of people who have the cancers we are targeting, as well as the subset of people 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 our most advanced product candidate, UCART19, to initially target a small
patient population that suffers from R/R ALL. 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.

If we fail to develop additional product candidates, our commercial opportunity will be limited.

One of our core strategies is to pursue clinical development of additional product candidates beyond UCART19, including ALLO-501 and ALLO-
715. Developing, obtaining regulatory approval and commercializing additional CAR T cell product candidates will require substantial additional funding and
is prone to the risks of failure inherent in medical product development. We cannot provide you any assurance that we will be able to successfully advance
any of these additional product candidates through the development process.

Even if we receive FDA approval to market additional product candidates for the treatment of cancer, we cannot assure you that any such product

candidates will be successfully commercialized, widely accepted in the marketplace or more effective than other commercially available alternatives. If we
are unable to successfully develop and commercialize additional product candidates, our commercial opportunity will be limited. Moreover, a failure in
obtaining regulatory approval of additional product candidates may have a negative effect on the approval process of any other, or result in losing approval of
any approved, product candidate.

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 plan to utilize an anti-CD52 monoclonal antibody as part of a lymphodepletion regimen to be infused prior to infusing our product candidates, such

as UCART19, ALLO-501 and ALLO-715. 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 other adverse effects. For instance, our
lymphodepletion regimen, including using an anti-CD52 antibody, will cause a transient and sometimes prolonged immune suppression.

In the ongoing CALM and PALL trials, we use a commercially available monoclonal antibody, alemtuzumab, that binds CD52. To secure our own

readily available source of anti-CD52 antibody, we are developing our own monoclonal anti-CD52 antibody, ALLO-647.  We plan to use ALLO-647 in our
clinical trial of ALLO-501 and, subject to regulatory acceptance, our clinical trial of ALLO-715. Subject to regulatory acceptance, Servier may also use
ALLO-647 in the Servier sponsored clinical trials of UCART19. However, we may be unable to agree with Servier an appropriate arrangement for the use
of ALLO-647, and we are dependent on Servier’s ability to progress the UCART19 trials, which are subject to delayed enrollment due to UCART19 supply
issues relating to the manufacturing UCART19. In addition, we may have to license certain rights relating to ALLO-647 from third parties. If we are unable to
secure such rights, we may not be able to progress the commercialization of ALLO-647.

If we are unable to successfully develop and manufacture ALLO-647 in the timeframe we anticipate, or at all, or if the FDA does 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 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.

44

 
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 facility requires substantial improvements and there can be no assurance that we will complete the build-out of our manufacturing
facility in a timely manner or at all.  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 dose will affect our ability to scale and our costs per dose. For instance,
because ALLO-715 may require a higher dose than ALLO-501, it is possible that it may be more difficult to scale ALLO-715 production.  As a result, we
may never be able to develop a commercially viable product. The commercial manufacturing facility we develop 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 current good manufacturing practices (cGMPs), 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 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 may fail to manage the logistics of storing and shipping our 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 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 overseas.

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

The CALM  and PALL clinical trials are currently being conducted in the United States and multiple countries in Europe, and we plan to globally

develop our future 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;

45

 
 
•

•

•

•

•

•

•

•

•

•

•

•

•

•

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

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;

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 geo-political actions, including war and terrorism.

These and other risks associated with our international operations and our collaborations with Servier and Cellectis, each based in France, 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. 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.”

46

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 Chairman, our President and Chief Executive Officer, our Chief Technical Officer and our Chief Financial Officer. In addition, we are currently
dependent on our TSA with Pfizer for personnel support. 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 that vest over time.

The value to employees of stock options 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 March 1, 2019, we had 122 full-time employees. As our development and commercialization plans and strategies develop, and as we continue to

transition into operating as a public company, we have rapidly expanded our employee base and expect to continue 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.

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

consultants, including Pfizer through the TSA, which expires after a certain period of time, to provide certain services, including certain research and
development as well as general and administrative support.  We plan to transition from Pfizer services and facilities throughout 2019 and the transition may
significantly disrupt our operations and be more expensive than we expect. 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. 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 and commercialize our product candidates and, accordingly, may not achieve our
research, development and commercialization goals.

47

 
 
 
 
We may form or seek 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 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 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 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 Exclusive License and Collaboration Agreement with Servier requires significant research and
development commitments that may not result in the development and commercialization of product candidates, including UCART19 and ALLO-501. 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.

In April 2018, we entered into an Asset Contribution Agreement with Pfizer pursuant to which we acquired certain assets and assumed certain

liabilities from Pfizer, including an Exclusive License and Collaboration Agreement with Servier and other intellectual property for the development and
administration of CAR T cells for the treatment of cancer. We also agreed to offer employment to certain Pfizer employees on terms no less favorable than the
terms such employees enjoyed while being employed by Pfizer. We also entered into a TSA with Pfizer pursuant to which Pfizer provides us with certain
services, including the services of their personnel, with respect to the assets that we purchased from Pfizer. Under the TSA, Pfizer also provides us with
certain facilities and facility management services, which terminate in 2019.

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 and licenses with Cellectis and Servier, 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 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.

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.

48

 
 
 
 
 
 
 
 
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 clinical development of our product candidates, including the planned clinical trials for

UCART19, ALLO-501 and ALLO-715. 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 trials for
multiple products. Further, if approved, we will require significant additional amounts in order to launch and commercialize our product candidates.

As of December 31, 2018, we had $721.4 million in cash and cash equivalents and available-for-sale 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. While we have not experienced any such material system
failure or security breach to date, if such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our
development programs and our business operations. For example, the loss of clinical trial data from completed or future clinical trials could result in delays in
our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach were
to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and
the further development and commercialization of our product candidates could be delayed.

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, and statutory, regulatory, and policy changes. Average review times at the agency
have fluctuated in recent years as a result. In addition, government funding of 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 years, including beginning on December 22, 2018, the U.S.
government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other
government employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely
review and process our regulatory submissions, which could have a material adverse effect on our business. 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.

49

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

Our operations, and those of our CMO, CROs and other contractors and consultants, could be subject to 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 planned 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. The U.S. healthcare laws and regulations that may affect our ability to operate include, but are not
limited to:

•

•

•

•

•

the federal Anti-Kickback Statute, which 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, the purchasing,
leasing, ordering or arranging for the purchase, lease, or order of any item or service reimbursable under Medicare, Medicaid or other federal
healthcare programs. The term “remuneration” has been broadly interpreted to include anything of value. Although 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 may be alleged to be intended to induce prescribing, purchases
or recommendations, include any payments of more than fair market value, and may be subject to scrutiny if they do not qualify for an exception
or safe harbor. In addition, a person or entity does not need to have actual knowledge of this statute or specific intent to violate it in order to have
committed a violation. In addition, the government may assert that a claim including items or services resulting from a violation of the federal
Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act and the civil monetary penalties statute;

federal civil and criminal false claims laws and civil monetary penalty laws, including the federal civil False Claims Act, which prohibit, among
other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment or approval from Medicare,
Medicaid, or other federal government programs that are false or fraudulent or knowingly making a false statement to improperly avoid, decrease
or conceal an obligation to pay money to the federal government, including federal healthcare programs;

the federal Health Insurance Portability and Accountability Act of 1996 (HIPAA), which created new federal criminal statutes that prohibit
knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or obtain, by means of false or
fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of, any healthcare
benefit program, including private third-party payors and knowingly and willfully falsifying, concealing or covering up by any trick, scheme or
device, a material fact or making any materially false, fictitious or fraudulent statements in connection with the delivery of, or payment for,
healthcare benefits, items or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of
the statute or specific intent to violate it in order to have committed a violation;

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act (HITECH) and their respective implementing
regulations, which impose requirements on certain covered healthcare providers, health plans, and healthcare clearinghouses as well as their
respective business associates that perform services for them that involve the use, or disclosure of, individually identifiable health information,
relating to the privacy, security and transmission of individually identifiable health information;

the federal Physician Payments Sunshine Act, which requires certain manufacturers of drugs, devices, biologicals and medical supplies for which
payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report annually to the
United States Department of Health and Human Services’ (HHS) Centers for Medicare & Medicaid Services (CMS) information related to
payments or other transfers of value made to physicians

50

 
 
 
 
 
 
and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members; and

•

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

Additionally, we may be subject to state, local and foreign equivalents of each of the healthcare laws described above, among others, some of which

may be broader in scope. For example, we may be subject to the following: state anti-kickback and false claims laws that may apply to sales or marketing
arrangements and claims involving healthcare items or services reimbursed by non-governmental third party payors, including private insurers, or that apply
regardless of payor; state laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the
relevant compliance guidance promulgated by the federal government; state and local laws that require drug manufacturers to report information related to
payments and other transfers of value to physicians and other healthcare providers or marketing expenditures; state laws that require the reporting of
information related to drug pricing; state and local laws requiring the registration of pharmaceutical sales and medical representatives; and state and foreign
laws governing the privacy and security of health information in some circumstances, many of which differ from each other in significant ways and often are
not preempted by HIPAA, thus complicating compliance efforts.

Because of the breadth of these laws and the narrowness of the statutory exceptions and regulatory safe harbors available, it is possible that some of

our business activities, or our arrangements with physicians, some of who receive stock options as compensation, could be subject to challenge under one or
more of such laws. If we or our employees, independent contractors, consultants, commercial partners and vendors violate these laws, we may be subject to
investigations, enforcement actions and/or significant penalties. We have adopted a code of business conduct and ethics, but it is not always possible to
identify and deter employee misconduct or business noncompliance, and the precautions we take to detect and prevent inappropriate conduct may not be
effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming
from a failure to be in compliance with such laws or regulations. Efforts to ensure that our business arrangements will comply with applicable healthcare laws
may involve substantial costs. It is possible that governmental and enforcement authorities will conclude that our business practices may not comply with
current or future statutes, regulations or case law interpreting applicable fraud and abuse or other healthcare laws and regulations. If any such actions are
instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business,
including the imposition of civil, criminal and administrative penalties, damages, disgorgement, monetary fines, imprisonment, possible exclusion from
participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, 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 curtailment of our operations, any of which could adversely affect our ability to operate our business and our results of
operations. In addition, the approval and commercialization of any of our product candidates outside the United States will also likely subject us to foreign
equivalents of the healthcare laws mentioned above, among other foreign laws.

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 consumers or households.  When it goes into effect on January 1, 2020, the CCPA will
require covered companies to provide new disclosures to

51

 
 
 
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. Legislators have stated that amendments will be proposed to the CCPA before it goes into effect, but it remains unclear what, if any, modifications
will be made to this legislation or how it will be interpreted. As currently written, the CCPA may impact (possibly significantly) 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 clinical trial insurance for our ALPHA trial, 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.

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 several years, including 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 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.

52

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

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 and taxes may be limited. As a result of our most recent private placements, our IPO and other transactions that have occurred in 2018, 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 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. 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, including Servier, 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. In addition, we depend on our collaborator, Servier, to sponsor and
lead the conduct of the CALM and PALL clinical trials.

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.

53

 
 
We may 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.

Servier is responsible for UCART19 manufacturing and is working with a CMO in Europe to provide clinical supply for the CALM and PALL clinical

trials. Servier is experiencing UCART19 supply issues relating to the manufacturing of UCART19, and, as a result, while the clinical trials of UCART19
remain active, they are not recruiting new patients. ALLO-501 has the same molecular design as UCART19, but is produced by a different CMO using a
different manufacturing process. ALLO-501 and ALLO-715 will be manufactured in the United States, at least initially, by a CMO, and we will manage all
other aspects of the supply, including planning, CMO oversight, disposition and distribution logistics. There can be no assurance that we or Servier will not
experience additional supply or manufacturing issues in the future.

While we have leased space to build a manufacturing facility, we must currently rely on outside vendors to manufacture supplies and process our

product candidates. 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.

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.

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

that we currently obtain through Cellectis, 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. 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.  

54

 
 
 
 
 
 
 
 
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 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.

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

donor material or delay in receiving donor material that meets our specifications, including specifications required by regulatory authorities, could adversely
affect our ability to manufacture sufficient supply of our product candidates.

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.

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.

55

 
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;

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 applying them on a patient by patient basis 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 of
UCART19 may, depending on the data, also result in the delay, suspension or termination of one or more clinical trials of UCART19, 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.

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 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. While it is uncertain when such processes intended to implement the BPCIA may be fully adopted by the FDA, any such processes 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.

56

 
 
 
 
 
 
 
 
 
 
 
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 this recommendation is likely to be applicable to our UCART19 product candidate; however, this
recommendation is not definitive until UCART19 obtains regulatory approval for commercialization.

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 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 product candidates.

If and when our ongoing and planned Phase 1 clinical trials for UCART19, ALLO-501 and ALLO-715 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 UCART19, ALLO-501 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. For ALLO-501, we may have
additional difficulties progressing to Phase 2 as we plan to introduce a second-generation ALLO-501 product candidate at the time of initiating Phase 2, and
the FDA may disagree with the plan or require a Phase 1 study of the second-generation ALLO-501 product candidate.

57

 
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.

ALLO-647 will also require regulatory review prior to its use in our clinical trials and the FDA may not accept the use of ALLO-647 in our clinical

trials in a timely manner or at all. In addition, 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 T cell product candidates. Additionally,
regulatory authorities may seek to understand the contribution of the lymphodepletion regimen, including the use of an anti-CD52 antibody, to any treatment
effect.  

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 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.

58

 
 
 
 
 
 
 
 
 
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 may 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.

Regenerative Medicine Advanced Therapy designation, even if granted for any of our product candidates, may not lead to a faster development or
regulatory review or approval process and it does not increase the likelihood that our product candidates will receive marketing approval.

We may seek Regenerative Medicine Advanced Therapy (RMAT) designation for one or more of our product candidates. In 2017, the FDA established
the RMAT designation to expedite review of a cell therapy, therapeutic tissue engineering product, human cell and tissue product, or any combination product
using such therapies or products, with limited exceptions intended to treat, modify, reverse, or cure a serious or life-threatening disease or condition and for
which preliminary clinical evidence indicates that 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. There is no assurance that we will be able to obtain RMAT designation for any of our product candidates. RMAT designation does not change
the FDA’s standards for product approval, and there is no assurance that such designation will result in expedited review or approval or that the approved
indication will not be narrower than the indication covered by the designation. Additionally, RMAT designation can be revoked if the criteria for eligibility
cease to be met as clinical data emerges.

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

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

59

 
We may also submit marketing applications in other countries. Regulatory authorities in jurisdictions outside of the United States have requirements

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

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

Any regulatory approvals that we receive for our product candidates will require surveillance to monitor the safety and efficacy of the product

candidate. The FDA may also require a risk evaluation and mitigation strategy, or REMS, in order to approve our product candidates, which could entail
requirements for a medication guide, physician communication plans or additional elements to ensure safe use, such as restricted distribution methods, patient
registries and other risk minimization tools. In addition, if the FDA or a comparable foreign regulatory authority approves our product candidates, the
manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion, import, export and recordkeeping for our
product candidates will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-
marketing information and reports, registration, as well as continued compliance with cGMPs and cGCPs for any clinical trials that we conduct post-approval.
As such, we and our contract manufacturers will be subject to continual review and inspections to assess compliance with cGMP and adherence to
commitments made in any BLA, other marketing application and previous responses to inspectional observations. Accordingly, we and others with whom we
work must continue to expend time, money and effort in all areas of regulatory compliance, including manufacturing, production and quality control. In
addition, the FDA could require us to conduct another study to obtain additional safety or biomarker information. Further, we will be required to comply with
FDA promotion and advertising rules, 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 and social media. Later discovery of previously unknown problems
with our product candidates, including adverse events of unanticipated severity or frequency, or with our third-party suppliers or manufacturing processes, or
failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market
studies or clinical studies to assess new safety risks; or imposition of distribution restrictions or other restrictions under a REMS program. Other potential
consequences include, among other things:

•

•

•

•

•

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

fines, warning letters or holds on clinical trials;

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

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

injunctions or the imposition of civil or criminal penalties.

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

60

 
 
 
 
 
 
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 willingness of patients to utilize our treatments or participate in clinical trials for our product candidates. Increased negative public opinion or more
restrictive government regulations in response thereto, 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
influential and we may not be able to convince them to use 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.

61

 
 
 
 
 
 
 
 
 
 
 
 
 
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.

Third-party payors decide which drugs and treatments they will cover and the amount of reimbursement. Reimbursement by a third-party payor may

depend upon a number of factors, including, but not limited to, the third-party payor’s determination that use of a product is:

•

•

•

•

•

a covered benefit under its health plan;

safe, effective and medically necessary;

appropriate for the specific patient;

cost-effective; and

neither experimental nor investigational.

Obtaining coverage and reimbursement of a product from a government or other third-party payor is a time-consuming and costly process that could

require us to provide to the payor supporting scientific, clinical and cost-effectiveness data for the use of our products. Even if we obtain coverage for a given
product, if the resulting reimbursement rates are insufficient, hospitals may not approve our product for use in their facility or third-party payors may
require co-payments that patients find unacceptably high. Patients are unlikely to use our product candidates unless coverage is provided and reimbursement
is adequate to cover a significant portion of the cost of our product candidates. Separate reimbursement for the product itself may or may not be available.
Instead, the hospital or administering physician may be reimbursed only for providing the treatment or procedure in which our product is used. Further, from
time to time, CMS revises the reimbursement systems used to reimburse health care providers, including the Medicare Physician Fee Schedule and Outpatient
Prospective Payment System, which may result in reduced Medicare payments. In some cases, private third-party payers rely on all or portions of Medicare
payment systems to determine payment rates. Changes to government healthcare programs that reduce payments under these programs may negatively impact
payments from private third-party payers, and reduce the willingness of physicians to use our product candidates.

In the United States, no uniform policy of coverage and reimbursement for products exists among third-party payors. Therefore, coverage and
reimbursement for products can differ significantly from payor to payor. 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.

We intend to seek approval to market our product candidates in both the United States and in selected foreign jurisdictions. If we obtain approval in

one or more foreign jurisdictions for our product candidates, we will be subject to rules and regulations in those jurisdictions. In some foreign countries,
particularly those in Europe, the pricing of biologics is subject to governmental control. In these countries, pricing negotiations with governmental authorities
can take considerable time after obtaining marketing approval of a product candidate. 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 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.

62

 
 
 
 
 
 
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. We are still unsure of the full impact that the Affordable Care Act will have on our
business.

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

the Affordable Care Act. Since January 2017, the U.S. President has signed two Executive Orders and other directives designed to delay, 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). On January 22, 2018, the U.S. President signed a continuing resolution on appropriations for fiscal year 2018 that delayed the implementation of certain
Affordable Care Act-mandated fees, including the so-called “Cadillac” tax on certain high cost employer-sponsored insurance plans, the annual fee imposed
on certain health insurance providers based on market share, and the medical device excise tax on non-exempt medical devices. 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 July 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. While
the Texas U.S. District Court Judge, as well as the Trump administration and CMS, have stated that the ruling will have no immediate effect pending appeal
of the decision, it is unclear how this decision, subsequent appeals, and other efforts to repeal and replace the Affordable Care Act will impact the Affordable
Care Act and our business.

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 2027, unless additional Congressional action is
taken. In January 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to
several 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.

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.

63

 
In addition, 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, review the relationship between pricing and manufacturer patient assistance programs, and reform government program
reimbursement methodologies for drugs. At the federal level, the U.S. President’s administration’s budget proposal for fiscal year 2019 contains further drug
price control measures that could be enacted during the 2019 budget process or in other future legislation, including, for example, measures to permit
Medicare Part D plans to negotiate the price of certain drugs under Medicare Part B, to allow some states to negotiate drug prices under Medicaid, and to
eliminate cost sharing for generic drugs for low-income patients. Further, the current U.S. President’s administration released a “Blueprint”, or plan, to lower
drug prices and reduce out of pocket costs of drugs that contains additional proposals to increase drug manufacturer competition, increase the negotiating
power of certain federal healthcare programs, incentivize manufacturers to lower the list price of their products, and reduce the out of pocket costs of drug
products paid by consumers. HHS has already started the process of soliciting feedback on some of these measures and, at the same, is immediately
implementing others under its existing authority. For example, in September 2018, CMS announced that it will allow Medicare Advantage Plans the option to
use step therapy for Part B drugs beginning January 1, 2019, and in October 2018, CMS proposed a rule that would require direct-to-consumer television
advertisements of prescription drugs and biological products, for which payment is available through or under Medicare or Medicaid, to include in the
advertisement the Wholesale Acquisition Cost, or list price, of that drug or biological product. On January 31, 2019, the HHS Office of Inspector General
proposed modifications to federal Anti-Kickback Statute safe harbors which, among other things, may affect rebates paid by manufacturers to Medicare Part
D plans, the purpose of which is to further reduce the cost of drug products to consumers. While some of these and other proposed measures may require
authorization through additional legislation to become effective, Congress and the current U.S. President’s administration have each indicated that it will
continue to seek new legislative and/or administrative measures to control drug costs. 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 cannot predict the initiatives that may be adopted in the future. The continuing efforts of the government, insurance companies, managed care

organizations and other payors of healthcare services to contain or reduce costs of healthcare and/or impose price controls may adversely affect:

•

•

•

•

•

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

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

our ability to generate revenue and achieve or maintain profitability;

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

the availability of capital.

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

which may adversely affect our future profitability.

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. 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.

64

 
 
 
 
 
 
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;

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 UCART19 and ALLO-501, and we hold the commercial rights to these

product candidates in the United States. Under the Servier Agreement, we also have an exclusive option to obtain the same rights to additional product
candidates targeting one additional cancer antigen. 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.

65

 
 
 
 
 
 
 
 
 
 
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 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 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. 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 UCART19, ALLO-501 or
another CAR-based product candidate 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.

66

 
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 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 UCART19 and our other 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.

67

 
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.

68

 
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 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, 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 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.

69

 
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

The price of our stock has been and may continue to be volatile, and you could lose all or part of your investment.

Prior to our IPO in October 2018, there was no public market for our common stock. We cannot assure you that an active, liquid trading market for our

shares will develop or persist. You may not be able to sell your shares quickly or at a recently reported market price if trading in our common stock is not
active. The trading price of our common stock following our IPO 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 our manufacturers or suppliers;

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;

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;

actual or anticipated variations in quarterly operating results;

our cash position;

our failure to meet the estimates and projections of the investment community or that we may otherwise provide to the public;

publication of research reports about us or our industry, or immunotherapy in particular, or positive or negative recommendations or withdrawal
of research coverage by securities analysts;

sales of our common stock by us or our stockholders in the future;

trading volume of our common stock;

changes in accounting practices;

ineffectiveness of our disclosure controls or internal controls;

disagreements with our auditor or termination of an auditor engagement;

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;

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 future earnings for the development, operation and expansion of our business and do not anticipate

declaring or paying any cash dividends for the foreseeable future. Any return to stockholders will therefore be limited to the appreciation of their stock.

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

We are an emerging growth company, as defined in the JOBS Act enacted in April 2012. For as long as we continue to be an emerging growth

company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not emerging
growth companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced
disclosure obligations regarding executive compensation and exemptions from the requirements of holding nonbinding advisory votes on executive
compensation and stockholder approval of any golden parachute payments not previously approved. We cannot predict if investors will find our common
stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active
trading market for our common stock and our stock price may be more volatile.

We will remain an emerging growth company until the earlier of (1) the last day of the fiscal year (a) following the fifth anniversary of the completion

of our IPO, (b) in which we have total annual gross revenue of at least $1.07 billion or (c) in which we are deemed to be a large accelerated filer, which
requires the market value of our common stock that is held by non-affiliates to exceed $700 million as of the prior June 30th, and (2) the date on which we
have issued more than $1 billion in non-convertible debt during the prior three-year period.

Under the JOBS Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as those standards
apply to private companies. We have elected to use this extended transition period for complying with new or revised accounting standards that have different
effective dates for public and private companies until the earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and
irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our financial statements may not be comparable to companies that
comply with new or revised accounting pronouncements as of public company effective dates.

71

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

As a public company, we have incurred and will continue to incur significant legal, accounting and other expenses that we did not incur as a private
company. We are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended (Exchange Act), which requires, among other
things, that we file with the Securities and Exchange Commission (SEC) annual, quarterly and current reports with respect to our business and financial
condition. In addition, the Sarbanes-Oxley Act, as well as rules subsequently adopted by the SEC and the Nasdaq Global Select Market to implement
provisions of the Sarbanes-Oxley Act, impose significant requirements on public companies, including requiring establishment and maintenance of effective
disclosure and financial controls and changes in corporate governance practices. Further, in July 2010, the Dodd-Frank Wall Street Reform and Consumer
Protection Act (Dodd-Frank Act) was enacted, pursuant to which the SEC adopted rules and regulations related to corporate governance and executive
compensation, such as “say on pay” and proxy access. Emerging growth companies are permitted to implement many of these requirements over a longer
period and up to five years following the completion of its initial public offering. We intend to take advantage of this legislation for as long as we are
permitted to do so. Once we become required to implement these requirements, we will incur additional compliance-related expenses. Stockholder activism,
the current political environment and the current high level of government intervention and regulatory reform may lead to substantial new regulations and
disclosure obligations, which may lead to additional compliance costs and impact the manner in which we operate our business in ways we cannot currently
anticipate.

We expect the rules and regulations applicable to public companies to continue to increase our legal and financial compliance costs and to make some

activities more time-consuming and costly. If these requirements divert the attention of our management and personnel from other business concerns, they
could have a material adverse effect on our business, financial condition and results of operations. The increased costs will decrease our net income or
increase our net loss, and may require us to reduce costs in other areas of our business or increase the prices of our products or services. For example, we
expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance and we have incurred
substantial costs to maintain the same or similar coverage. We cannot predict or estimate the amount or timing of additional costs we may incur to respond to
these requirements. The impact of these requirements could also make it more difficult for us to attract and retain qualified persons to serve on our board of
directors, our board committees or as executive officers.

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, 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.

Substantially all of our pre-IPO stockholders are subject to lock-up agreements with the underwriters of our IPO that restrict their ability to transfer
shares of our common stock or securities convertible into or exercisable or exchangeable for shares of our common stock until April 9, 2019. The lock-up
agreements limit the number of shares of common stock that may be sold immediately following our IPO. As of March 1, 2019, there are 121,482,671 shares
of stock outstanding, including 23,698,453 shares issued but subject to repurchase, as described under Note 11 and to our financial statements appearing
elsewhere in this report. Subject to certain limitations, approximately 100,782,671 shares will become eligible for sale upon expiration of the lock-up period,
a portion of which will be subject to repurchase. Sales of stock by these stockholders could have a material adverse effect on the trading price of our common
stock.

Certain holders of our securities are entitled to rights with respect to the registration of their shares under the Securities Act, subject to the 180-day

lock-up agreements described above. Registration of these shares under the Securities Act would result in the shares becoming freely tradable without
restriction under the Securities Act. Any sales of securities by these stockholders could have a material adverse effect on the trading price of our common
stock.

We have registered on Form S-8 all shares of common stock that are issuable under our 2018 Plan. As a consequence, these shares can be freely sold

in the public market upon issuance, subject to volume limitations applicable to affiliates and the lock-up agreements described above.

72

 
Future sales and issuances of our common stock or rights to purchase common stock, including pursuant to the 2018 Plan, could result in additional
dilution of the percentage ownership of our stockholders and could cause our stock price to fall.

We expect that significant additional capital may be needed in the future to continue our planned operations, including conducting clinical trials,
commercialization efforts, expanded research and development activities and costs associated with operating a public company. To raise capital, we may sell
common stock, convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. If we
sell common stock, convertible securities or other equity securities, investors may be materially diluted by subsequent sales. Such sales may also result in
material dilution to our existing stockholders, and new investors could gain rights, preferences and privileges senior to the holders of our common stock.

Pursuant to the 2018 Plan, our management is authorized to grant stock options to our employees, directors and consultants.

The aggregate number of shares of our common stock that may be issued pursuant to stock awards under the 2018 Plan is 15,409,983 shares.
Additionally, the number of shares of our common stock reserved for issuance under the 2018 Plan will automatically increase on January 1 of each year and
continuing through and including January 1, 2028, by 5% of the total number of shares of our capital stock outstanding on December 31 of the preceding
calendar year, or a lesser number of shares determined by our board of directors. Unless our board of directors elects not to increase the number of shares
available for future grant each year, our stockholders may experience additional dilution, which could cause our stock price to fall.

We have broad discretion in the use of the net proceeds from our IPO and may not use them effectively.

Our management has broad discretion in the application of the net proceeds from our IPO, including for any of the purposes described in the section of

our final prospectus, filed with the SEC on October 11, 2018, titled “Use of Proceeds”. Because of the number and variability of factors that will determine
our use of the net proceeds from our IPO, their ultimate use may vary substantially from the use described in the final prospectus. Our management might not
apply our net proceeds in ways that ultimately increase the value of your investment. The failure by our management to apply these funds effectively could
harm our business. Pending their use, we may invest the net proceeds from our IPO in short-term, investment-grade, interest-bearing securities. These
investments may not yield a favorable return to our stockholders. If we do not invest or apply the net proceeds from our IPO in ways that enhance stockholder
value, we may fail to achieve expected financial results, which could cause our stock price to decline.

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 chairman 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.

73

 
 
 
 
 
 
 
 
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.

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 will 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
do not initiate coverage of us, 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.

We occupy approximately 21,544 square feet of office and laboratory space in South San Francisco, California pursuant to our Transition Services

Agreement (TSA) with Pfizer. In August 2018, we entered into a new lease for approximately 68,000 square feet for office and laboratory space in South San
Francisco that will serve as our headquarters. We expect to transition from the Pfizer facilities and complete occupancy in our headquarters by the end of the
third quarter of 2019. 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 has an initial term of 15 years and eight months. We expect the lease to commence in March 2020.

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 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.

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

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 as a result of 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, 2018, we have not used any of

the net proceeds from our IPO. The net proceeds from our IPO will be 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

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.

In collaboration with Servier, we are developing UCART19 and ALLO-501, chimeric antigen receptor (CAR) T cell product candidates targeting
CD19. Servier is sponsoring two Phase 1 clinical trials of UCART19 in patients with relapsed/refractory (R/R) B-cell precursor acute lymphoblastic leukemia
(ALL), one for adult patients (the CALM trial) and one for pediatric patients (the PALL trial). In January 2019, the U.S. Food and Drug Administration
(FDA) cleared our investigational new drug application (IND) for ALLO-501, and we plan to initiate a Phase 1/2 clinical trial (the ALPHA trial) in the first
half of 2019 for the treatment of R/R non-Hodgkin lymphoma (NHL). In addition, we have a deep pipeline of allogeneic CAR T cell product candidates
targeting multiple promising antigens in a host of hematological malignancies and solid tumors. For example, we plan to submit an IND and initiate a Phase 1
clinical trial in 2019 for ALLO-715, an allogeneic CAR T cell product candidate targeting B-cell maturation antigen (BCMA) for the treatment of R/R
multiple myeloma.

Servier is the sponsor of the UCART19 clinical trials and is also responsible for manufacturing UCART19.  Servier is experiencing UCART19 supply

issues relating to the manufacturing of UCART19, and, as a result, while the clinical trials of UCART19 remain active, they are not recruiting new patients.
We will be the sponsor of the clinical trials for ALLO-501 and ALLO-715, and we will also be responsible for manufacturing ALLO-501 and ALLO-715. We
believe the UCART19 supply issues have no effect on our manufacturing or program timelines for ALLO-501 and ALLO-715. We will also manage all other
aspects of the supply of ALLO-501 and ALLO-715, including planning, contract manufacturing oversight, disposition and distribution logistics.

Since inception, we have had significant operating losses, the majority of which are attributable to acquired intangible in-process research and
development costs pursuant to the Asset Contribution Agreement with Pfizer Inc. (Pfizer) described below. Our net loss was $211.5 million for the year ended
December 31, 2018. As of December 31, 2018, we had an accumulated deficit of $211.5 million. As of December 31, 2018, we had $721.4 million 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, general and administrative expenses, and capital expenditures will continue to increase.

Our Research 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 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 S.A. (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 financial statements and Item 9B “Other Information” each included elsewhere in this report for further descriptions of the prior
agreement with Cellectis and the new license agreement with Cellectis.

78

 
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 additional
products, including other allogeneic anti-CD19 CAR product candidates. In April 2018, Pfizer assigned the agreement to us pursuant to the Pfizer Agreement.
See Note 7 to our financial statements included elsewhere in this report for further description of the Servier Agreement.

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 Pfizer provides us with 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 provides us with certain
facilities and facility management services. The services are provided by certain employees of Pfizer as independent contractors of Allogene. We believe that
it is 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 agreed to provide the services for a period of time ranging from one to 12 months thereafter,

depending on the service, which we refer to as the Service Period, with the exception of the services relating to the facilities, which Pfizer agreed to provide
for up to 18 months. The services and employees for each service may be amended from time to time by the parties. Under the TSA, total expenses were
$10.1 million for the year ended December 31, 2018 and we estimate we will pay Pfizer an aggregate of $3.8 million in 2019.

The TSA provides that Pfizer will indemnify us for damages that result from Pfizer’s gross negligence, willful misconduct or material breach of the
TSA and that we will indemnify Pfizer for damages that arise from the provision of the services, unless such damages result from Pfizer’s gross negligence,
willful misconduct or material breach. We are also required to indemnify Pfizer for damages that arise from our material breach of the TSA.

The term of the agreement began in April 2018 and ends on the earlier to occur of the last date that Pfizer is required to provide the services or the
termination of the TSA in accordance with the agreement. Either party may terminate the agreement upon 60 days’ prior written notice in the event of the
other party’s uncured material breach. Pfizer may terminate the TSA upon 10 days’ prior written notice in the event of our non-payment, if left uncured. We
may terminate our use of the facilities with 60 days’ written notice.

Components of Results of Operations

Operating Expenses

Research and Development

To date, our research and development expenses have related primarily to discovery efforts and preclinical and clinical development of our product

candidates. Research and development expenses for the year ended December 31, 2018 includes acquired in-process research and development costs of
$109.4 million recognized as a non-cash expense related to the Pfizer Agreement. Additional research and development expenses were incurred in the year
related to development of pipeline product candidates UCART19, ALLO-501 and ALLO-715. The most significant research and development expenses for
the year relates to costs incurred for the development of our most advanced product candidates, UCART19 and ALLO-501, which 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 production of clinical materials, including fees paid 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; and

facilities and other expenses, which include expenses for rent and maintenance of facilities, depreciation and amortization expense and other
supplies.

79

 
 
 
 
 
 
Other significant research and development costs include costs relating to facilities and overhead costs, including payments to Pfizer under the TSA

for use of their facilities. 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, the 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 development of UCART19, including for the CALM and PALL clinical

trials. We accrue for costs incurred by monitoring the status of the CALM and PALL 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, including for
the ALPHA clinical trial. Collaboration expenses and cost reimbursement is recorded on a net basis as a research and development expense in our 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 over the next several years as our UCART19, ALLO-501 and ALLO-715 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;

the cost 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 number of doses 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 the case of UCART19, we are also dependent on Servier’s ability to manage the CALM and PALL clinical trials. In addition, the probability of
success for each product candidate will depend on numerous factors, including 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.

80

 
 
 
 
 
 
 
 
 
 
 
 
General and Administrative

General and administrative expenses consist primarily of salaries and other staff-related costs, including stock-based compensation for options granted

and modification of shares of common stock issued to our founders to include vesting conditions, for personnel in executive, finance, accounting, legal,
investor relations, facilities, business development, information technology and human resources functions. Other significant costs include costs relating to
facilities and overhead costs, including payments to Pfizer under the TSA for use of their facilities, 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. These
increases are anticipated to include increased costs related to the hiring of additional personnel, developing commercial 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.

Change in Fair Value of 2018 Notes

In September 2018, we entered into a note purchase agreement pursuant to which 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. From issuance to settlement, the change in fair value of the 2018 Notes was recognized in the statement of operations and comprehensive loss.
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 equivalents and investment gains and losses recognized during the period.

Results of Operations

Year Ended December 31, 2018

For the period from November 30, 2017 (inception) to December 31, 2017, we incurred $2,000 in start-up costs to establish our company. Principal
operations commenced in April 2018 when we acquired certain assets from Pfizer and completed a Series A and A-1 preferred stock financing.  Due to our
limited operations in 2017, the following discussion does not contain a comparison of the results of operations for the period from November 30, 2017
(inception) to December 31, 2017.

Research and Development Expenses

Research and development expenses were $151.9 million for the year ended December 31, 2018 which consisted primarily of $109.4 million of in-
process research and development acquired from Pfizer which was primarily related to anti-CD19 CAR T cell therapy. The remaining expense is primarily
due to $15.8 million in external costs related to our clinical programs UCART19, ALLO-501 and ALLO-715, $13.1 million in personnel-related costs, of
which $1.7 million is stock-based compensation expense, $5.2 million for expenses incurred under the TSA, and $4.2 million in net external collaboration
partner costs related to product candidate development activities and manufacturing support for UCART19 clinical trials. We expect research and
development expenses will remain significant and will increase as we initiate funding of our planned clinical trials for ALLO-501 and ALLO-715 and
continue to fund clinical trials for UCART19.

General and Administrative Expenses

General and administrative expenses were $41.0 million for the year ended December 31, 2018. General and administrative expenses consisted

primarily of $14.9 million in stock-based compensation related to vesting of modified founders’ shares, $2.0 million of expense for all other stock-based
compensation, $6.5 million for personnel-related costs, $6.5 million in legal fees and professional consulting service fees related to supporting the growth of
the Company, and $4.9 million for expenses incurred under the TSA.

Change in Fair Value of 2018 Notes

The change in fair value of the 2018 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.

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.  

Interest and Other Income, Net

Interest and other income, net was $5.8 million for the year ended December 31, 2018 and primarily consists of interest earned on our investments and

cash equivalents during the period.

Liquidity, Capital Resources and Plan of Operations

To date, we have incurred significant net losses and negative cash flows from operations. 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 and net proceeds from our IPO.

In connection with our IPO, we sold an aggregate of 20,700,000 shares of our common 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. At the
closing of the IPO, the 2018 Notes were automatically converted into 7,856,176 shares of common stock. As of December 31, 2018, we had $721.4 million in
cash, cash equivalents and investments.

Capital Resources

Our primary use of cash is to fund operating expenses, which consist primarily of clinical manufacturing and research and development expenditures

related to UCART19, ALLO-501 and ALLO-715, and 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.

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 arrangements. If 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.

Operating Activities

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, 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

83

 
 
 
 
 
 
 
 
 
  
 
 
 
 
 
 
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, 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.

In August 2018, we entered into an operating lease agreement for our new 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 office and laboratory space in South San Francisco near the 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.

Commitments

Our commitments primarily consist of obligations under our agreements with Pfizer, Cellectis and Servier. 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, 2018, we were unable to estimate the timing or likelihood of achieving the milestones or making
future product sales.

Additionally, we have entered into an agreement 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.

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.

In addition, subsequent to December 31, 2018, we entered into a lease agreement to develop a manufacturing facility. For additional information
regarding this lease agreement, including our payment obligations, see Note 17 to our financial statements appearing elsewhere in this Annual Report.  

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 financial statements, which have been

prepared in accordance with United States generally accepted accounting principles. The preparation of these 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
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, research and development expenses,
stock-based compensation and leases have the most significant impact on our 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 balance sheets and within research and development expense on the 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.

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 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.

85

 
 
 
-

-

-

-

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 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 year ended December 31, 2018, stock-based compensation was $18.6 million. As of December 31, 2018, we had $42.8 million of total
unrecognized stock-based compensation which we expect to recognize over a weighted-average period of 3.5 years. In addition, we recorded $14.9 million in
stock-based compensation as a result of the modification of our founders’ shares of common stock to include vesting conditions.

Leases

We early adopted Accounting Standards Update (ASU) No. 2016-02, Leases as of January 1, 2018 in accordance with ASC 250, Accounting Changes
and Error Corrections. For our long-term operating leases, we recognized right-of-use assets and lease liabilities on our 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 statements

of operations and comprehensive loss. Variable lease payments include lease operating expenses.

We elected to exclude from our 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 financial statements for a discussion of new accounting standards updates that may impact us.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Interest Rate Risk

Our cash, cash equivalents and investments of $721.4 million as of December 31, 2018, 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, 2018 would not have a material effect on the fair market value of our cash
equivalents and available-for-sale securities.

Foreign Exchange Rate Risk

Our collaboration agreement with Servier requires collaboration payments for shared clinical development costs to be paid in foreign currency, 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 foreign exchange rates during the periods presented
would not have had a material effect on our consolidated financial statements. As of December 31, 2018, we had $4.4 million of liabilities denominated in
foreign currencies.

To the Stockholders and the Board of Directors of
Allogene Therapeutics, Inc.

Opinion on the Financial Statements

We have audited the accompanying balance sheets of Allogene Therapeutics, Inc. (the Company) as of December 31, 2018 and 2017, the related

statements of operations and comprehensive loss, statements of convertible preferred stock and stockholders’ equity (deficit) and cash flows for the year
ended December 31, 2018 and the period from November 30, 2017 (inception) to December 31, 2017, and the related notes (collectively referred to as the
“financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company at December 31,
2018 and 2017, and the results of its operations and its cash flows for the year ended December 31, 2018 and the period from November 30, 2017 (inception)
to December 31, 2017, in conformity with U.S. generally accepted accounting principles.

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 Public Company Accounting Oversight Board (United States)
(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. The Company is not required to
have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an
understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal
control over financial reporting. Accordingly, we express no such opinion.

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.

Notes to 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).

Initial Public Offering

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 10) 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.

Deferred Offering Costs

Offering costs, including legal, accounting, and filing fees related to the IPO, were deferred and were offset against the offering proceeds upon the

completion of the IPO. Upon the completion of the IPO in October 2018, $3.2 million of deferred offering costs were reclassified to additional paid in capital.
There were no deferred offering costs capitalized as of December 31, 2017.

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 and cash equivalents and investments of $721.4 million as of December 31, 2018. Since inception through December 31, 2018, the
Company has incurred cumulative net losses of $211.5 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.

The Company intends to raise such 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 a period of at least one year from the date the financial statements are filed with the Securities and Exchange Commission (SEC).

Basis of Presentation

The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of

America (GAAP).

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. 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 financial statements and the reported amounts of expenses during the reporting period. Significant estimates and assumptions
made in the accompanying 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, 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, 2018, 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 industry 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

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 money market accounts.

The Company has issued letters of credit under separate lease agreements which have been collateralized by restricted cash. This cash is classified as

long-term restricted cash on the accompanying balance sheet based on the terms of the underlying leases.

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. Investments with original maturities
beyond three months at the date of purchase and which mature at, or less than twelve months from the balance sheet date are classified as current.

94

 
Unrealized gains and losses are excluded from earnings and are reported as a component of comprehensive loss. 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 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 repairs are charged to operations as incurred. Upon sale or
retirement of assets, the cost and related accumulated depreciation are removed from the balance sheet and the resulting gain or loss is reflected in operations.

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

Leases

The Company early adopted Accounting Standards Update (ASU) No. 2016-02, 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 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 statements

of operations and comprehensive loss. Variable lease payments include lease operating expenses.

The Company elected to exclude from its 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.

95

 
 
 
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 balance sheets and within research and development expenses on the 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 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 year ended
December 31, 2018 this was comprised of unrealized gains and losses, net of tax, on the Company’s investments. For the period from November 30, 2017
(inception) to December 31, 2017, comprehensive net loss was equal to net loss.

Definite-Lived Intangible Assets

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.

96

 
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 the carrying amount of an asset group exceeds its estimated future cash flows, an impairment charge is recognized in the
amount by which the carrying amount of the asset group exceeds the fair value of the asset group. 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 has been no impairment of long-lived assets for any of the periods presented.

Research and Development Expenses

Research and development costs are expensed as incurred. Research and development expenses for the year ended December 31, 2018 primarily
consist of acquired intangible assets pursuant to the Asset Contribution Agreement with Pfizer (see Note 6) as, at the time of acquisition of the asset, the
technology was under development; was not approved by the U.S. Food and Drug Administration or other regulatory agencies for marketing; had not reached
technical feasibility; or otherwise had no foreseeable alternative future use. For the year ended December 31, 2018, the Company recognized expense of
$109.4 million related to the acquired intangible in-process research and development.

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 the Company’s behalf. Costs associated with co-development
activities performed under the various license and collaboration agreements are included in research and development expenses.

Note 2. Recent Accounting Guidance

Recently Adopted Accounting Pronouncements

In January 2017, the FASB issued Accounting Standards Update, Business Combinations (Topic 805): Clarifying the Definition of a Business
(ASU 2017-01). ASU 2017-01 clarifies the framework for determining whether an integrated set of assets and activities meets the definition of a business.
The revised framework establishes a screen for determining whether an integrated set of assets and activities is a business and narrows the definition of a
business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable
asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. This
new accounting guidance is effective for public or private companies for fiscal years beginning after December 15, 2017, including interim periods within
those fiscal years. Early adoption is permitted. The new accounting guidance should be applied prospectively on or after the effective date. The Company
adopted this guidance on January 1, 2018.

In June 2018, the FASB issued Accounting Standards Update No. 2018-07, Improvements to Nonemployee Share-Based Payment Accounting

(ASU 2018-07). ASU 2018-07 simplifies the accounting for share-based payments to nonemployees by aligning it with the accounting for share-based
payments to employees, with certain exceptions. Some of the areas of simplification apply only to nonpublic entities. For all entities, the amendments are
effective for annual periods beginning after December 15, 2019, and interim periods within annual periods beginning after December 15, 2020. Early
adoption is permitted for any entity in any interim or annual period for which financial statements haven’t been issued or made available for issuance, but not
before an entity adopts ASC 606. The Company early adopted this guidance on January 1, 2018. As a result, the accounting for share-based payments to
nonemployee consultants is consistent with employees.

In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows: Restricted Cash.  This ASU requires

changes in restricted cash during the period to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total
amounts shown on the statement of cash flows. If cash, cash equivalents and restricted cash are presented in more than one line item on the balance sheet, the
new guidance requires a reconciliation of the total in the statement of cash flows to the related captions in the balance sheet.  This guidance is effective for
annual and interim periods of public entities beginning after December 15, 2017, with early adoption permitted. The amendments in this ASU should be
applied retrospectively to all periods presented. The Company adopted this guidance on January 1, 2018. The adoption of this ASU increased our ending cash
balances within the statements of cash flows. The adoption had no other material impacts to the statements of cash flows and had no impact on the results of
operations or financial position.

97

 
In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (ASU 2016-02), which provides revised accounting
requirements for both lessees and lessors. Lessees will recognize a right-of-use asset and a lease liability for virtually all leases (other than short-term leases
upon election). The liability is recognized at the present value of future lease payments. The asset is recognized based on the liability. For statements of
operations purposes, ASU 2016-02 requires leases to be classified as either operating or finance. Operating leases will result in straight-line expense while
finance leases will result in a front-loaded expense pattern. ASU 2016-02 is effective for public companies for fiscal years beginning after December 15,
2018. Early adoption is permitted. The standard requires a modified-retrospective transition method and provides for certain practical expedients. The
Company early adopted the new lease standard on July 1, 2018 with the adoption reflected as of January 1, 2018 in accordance with ASU No. 2018-11,
Leases (Topic 842) –Targeted Improvements. There were no lease arrangements prior to August 2018 and consequently, the adoption of the standard did not
have any impact on periods prior to August 2018.

Recent Accounting Pronouncements Not Yet Adopted

In February 2018, the FASB issued Accounting Standards Update No. 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220):
Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which provided amended guidance to allow a reclassification from
accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. Additionally, under the new
guidance, an entity will be required to provide certain disclosures regarding stranded tax effects. The guidance is effective for fiscal years beginning after
December 15, 2018, with early adoption permitted. The Company does not expect the adoption of this standard to have a material effect on its financial
statements.

In August 2018, the FASB issued Accounting Standards Update No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes

to the Disclosure Requirements for Fair Value Measurement, which eliminates certain disclosure requirements for fair value measurements for all entities,
requires public entities to disclose certain new information and modifies some disclosure requirements. This standard is effective for fiscal years beginning
after December 15, 2019, with early adoption permitted. The Company does not expect the adoption of this standard to have a material effect on its 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. The guidance is effective for fiscal years beginning after December 15, 2019,
with early adoption permitted. The Company is evaluating the impact of adopting this amendment to its 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.

There were no Level 3 assets or liabilities at December 31, 2018.

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, 2018 are presented in the following table:

Included within cash and cash equivalents on the Company’s balance sheet

The carrying amounts of accounts payable and accrued liabilities approximate their fair values due to their short-term maturities. The Company’s

Level 2 securities are valued using third-party pricing sources. The pricing services utilize industry standard valuation models, including both income and
market-based approaches, for which all significant inputs are observable, either directly or indirectly.

There were no transfers of assets between the fair value measurement levels during the year ended December 31, 2018.

As of December 31, 2018, the remaining contractual maturities of available-for-sale securities were less than three years. There have been no
significant realized losses on available-for-sale securities for the year ended December 31, 2018. Based on our review of our available-for-sale securities, we
believe we had no other-than-temporary impairments on these securities as of December 31, 2018, because we do not intend to sell these securities nor do we
believe that we will be required to sell these securities before the recovery of their amortized cost basis. Gross realized gains and gross realized losses were
immaterial for the year ended December 31, 2018.

Note 6. Asset Acquisition

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 2017-01. 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):

  $  

3,258 

103,936 
5,500 
1,206 
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 is 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 year ended December 31,
2018. These contingent payments are 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 is 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. No such payments were made in the year ended December 31, 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). Pursuant to the Original Cellectis Agreement, the Company has an exclusive, worldwide, royalty-bearing,
sublicensable license, on a target-by-target basis, under certain of Cellectis’s intellectual property to make, use, sell, import, and otherwise commercialize
products directed at certain targets for the treatment of cancer.

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. Pursuant to the terms of the Original Cellectis Agreement, the research collaboration ended in June 2018.
Cellectis has a non-exclusive, worldwide, royalty-free, perpetual and irrevocable license, with sublicensing rights under certain conditions, under certain of
the Company’s intellectual property to conduct research, and to make, use, sell, import and otherwise commercialize products directed at Cellectis-selected
targets.

The Original Cellectis Agreement requires the Company to make payments of up to $185.0 million per product that is directed against a Company-
selected target, with aggregate maximum potential pre-clinical, clinical and commercial milestone payments totaling up to $2.8 billion across all potential
targets. 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, or are covered by, certain of Cellectis’s intellectual property at rates in the high single-digit percentages.

102

 
Unless earlier terminated in accordance with the agreement, the Original Cellectis Agreement will expire on a product-by-product and country-by-

country basis, on 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 will
the term extend, with respect to a particular licensed product, past the twentieth anniversary of the first commercial sale for such product.

All costs the Company incurred in connection with this agreement were recognized as research and development expenses. For the year ended

December 31, 2018, $0.4 million of costs have been incurred associated with research services performed by Cellectis.

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 products, including other anti-CD19 product candidates.

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 generally not required to make any additional payments to Servier to exercise an option, except
for products directed at a certain target, for which the Company is required to pay Servier an option fee in the low tens of millions of dollars range upon
exercise. If the 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 and ALLO-501, 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 on a target-by-target

basis. For products directed against CD19, including UCART19, 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. The total potential payments that the Company is obligated to make under the Servier
Agreement upon successful completion of regulatory and sales milestones are $381.5 million, including the CD19-related milestone payments described
above. 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 ($81.9 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.

103

 
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, 2018 the Company recorded development costs of $4.2 million incurred under the collaboration agreement with

Servier. These costs were recognized as research and development expenses.

Note 8. Leases

In August 2018, the Company entered into an operating lease agreement for new office and laboratory space which consists of approximately 68,000
square feet located in South San Francisco, California. The lease term is 127 months beginning August 2018 through February 2029 with an option to extend
the term for another seven years which is not reasonably assured of exercise. The Company has the right to make tenant improvements, including the addition
of laboratory space, with a lease incentive allowance of $5.1 million. The rent payments begin on March 1, 2019 after an abatement period. In connection

Note 9. Commitments and Contingencies

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.

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.

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 year ended December 31, 2018, the Company recognized $21.2 million 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 (Deficit)

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.

In April 2018, the Company issued 7,557,990 shares of its Series A convertible preferred stock at a price per share of $35.06 for net cash proceeds of
$264.4 million and issued 998,225 shares of Series A-1 convertible preferred stock at a price per share of $35.06 for net cash proceeds of $34.9 million. Fifty
percent of the aggregate purchase price of $300.0 million was paid in April 2018. The remaining subscriptions receivable of $150.0 million was 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, 2018.

Common Stock

Pursuant to the Amended and Restated Certificate of Incorporation filed on October 15, 2018, as amended, the Company was authorized to issue a

total of 200,000,000 shares of common stock, of which 121,482,671 shares were issued and outstanding at December 31, 2018.

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, 2018, 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 the 2018 Equity Incentive Plan (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
October 2018, the Board of Directors approved an amendment and restatement of the 2018 Plan, increasing the shares of common stock issuable under the
2018 Plan as well as allowing for an automatic annual increase to the shares issuance under the 2018 Plan to the 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. 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, 2018, there were 8,176,125 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 Capital Market on December 31, 2018. During the year
ended December 31, 2018, the estimated weighted-average grant-date fair value of employee options granted was $3.75 per share. As of December 31, 2018,
there was $42.8 million of unrecognized stock-based compensation related to unvested stock options, which is expected to be recognized over a weighted-
average period of 3.5 years. No options had vested during the year ended December 31, 2018.

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,
2018

$2.27 - $26.52
5.99 to 6.25

74.2% - 77.0%  
2.74% - 2.99%  

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 year ended December 31, 2018, total stock-based compensation expense related to stock options was $3.3 million.

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. 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:

Expected term (in years)
Volatility
Risk-free interest rate
Dividend yield

Year Ended
December 31,
2018
0.50 – 2.00
67.7% - 81.8%
2.37% - 2.83%
—

For the year ended December 31, 2018, total stock-based compensation expense related to ESPP was $0.4 million.

Founders’ Stock

Stock-based compensation expense is recognized for shares of founders’ stock as vesting conditions are met. In relation to the modification described

in Note 11, 24,230,750 shares of founders’ stock remained unvested at the modification date in April 2018. For the year ended December 31, 2018, $14.9
million of stock-based compensation expense was recognized related to the vesting of 6,562,506 shares of founder stock. At December 31, 2018 there was
$44.6 million of unrecognized stock-based compensation expense related to 19,687,487 shares of unvested founders’ stock which is expected to be
recognized over 3.2 years. The weighted-average fair value at grant date for founders’ stock was $2.27 per share.

Early Exercised Options

The Company allows certain of its employees and its directors to exercise options granted under 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 year ended December 31, 2018 5,020,580 options were
early exercised. As of December 31, 2018, there was $4.6 million recorded in accrued and other liabilities and $6.8 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 financial
statements since the exercise date.

Note 13. Related Party Transactions

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 $41.9 million during
the year ended December 31, 2018.

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.

Income tax expense or benefit from continuing operations is generally determined without regard to other categories of earnings, such as discontinued

operations and other comprehensive income.  An exception is provided in ASC 740 when there is aggregate income from categories other than continuing
operations and a loss from continuing operations in the current year.  In this case, the tax benefit allocated to continuing operations is the amount by which the
loss from continuing operations reduces the tax expenses recorded with respect to the other categories of earnings, even when a valuation allowance has been
established against the deferred tax assets.  In instances where a valuation allowance is established against current year losses, income from other sources,
including gain from available-for-sale investments recorded as a component of other comprehensive income, is considered when determining whether
sufficient future taxable income exists to realize the deferred tax assets.  For the year ended December 31, 2018, the Company recorded a tax benefit of $0.1
million 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

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, 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 from inception.

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 as the inclusion of

all potential dilutive securities would have been anti-dilutive. Potentially dilutive securities that were not included in the diluted per share calculations
because they would be anti-dilutive were as follows:

Stock options to purchase common stock

Note 17. Subsequent Events

In February 2019, the Company entered into a lease agreement for approximately 118,000 square feet of space to develop a cell therapy manufacturing

facility in Newark, California. The lease has a term of fifteen years and eight months, and is expected to commence in March 2020. Upon certain conditions,
the Company has two ten-year options to extend the lease. Subject to rent abatement for the second through nine months of the lease, the Company will be
required to pay $159,150 per month for rent for the first twelve months of the lease term which will increase at a rate of 3% per year. The Company will be
entitled to a tenant improvement allowance of $2.9 million for costs related to the design and construction of certain Company improvements. In connection
with the lease, the Company will maintain a letter of credit for the benefit of the landlord in the amount of $3.0 million.

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, 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.

The material rights and obligations of the parties under the Cellectis Agreement are otherwise consistent with the material rights and obligations of the

parties under the Original Cellectis Agreement.

Item 9A. Controls and Procedures.

Conclusions Regarding the Effectiveness of Disclosure Controls and Procedures

As of December 31, 2018, 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, 2018, the design and operation of our disclosure
controls and procedures were effective at a reasonable assurance level.

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. During the year ended December 31, 2018, we implemented an equity management
system as well as hired additional experienced staff in an effort to strengthen our overall control environment. Other than these changes mentioned, there were
no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over
financial reporting.

Management’s Report on Internal Control over Financial Reporting

This Annual Report on Form 10-K does not include a report of management’s assessment regarding internal control over financial reporting or an

attestation report of our independent registered public accounting firm due to a transition period established by the rules of the SEC for newly public
companies.

Item 9B. Other Information.

On March 8, 2019, we entered into a License Agreement (the Cellectis Agreement) with Cellectis.  In connection with the execution of the Cellectis

Agreement, on March 8, 2019, we and Cellectis also entered into a letter agreement (the Letter Agreement), pursuant to which we 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.

The material rights and obligations of the parties under the Cellectis Agreement are otherwise consistent with the material rights and obligations of the

parties under the Original Cellectis Agreement.

Pursuant to the Cellectis Agreement, Cellectis granted to us 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 us 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 us in April 2018, will survive the termination of the Original Cellectis Agreement.

Pursuant to the Cellectis Agreement, we granted Cellectis a non-exclusive, worldwide, royalty-free, perpetual and irrevocable license, with

sublicensing rights under certain conditions, under certain of our intellectual property, to make, use, sell, import and otherwise commercialize CAR T
products directed at certain targets (the Cellectis Targets).

115

 
The Cellectis Agreement provides for development and sales milestone payments by us 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. We expect to pay Cellectis $5.0 million upon
the dosing of the first patient in its Phase 1 clinical trial of ALLO-715. Cellectis is also eligible to receive tiered royalties on annual worldwide net sales of
any products that are commercialized by us that contain or incorporate, are made using or are claimed or covered by, Cellectis intellectual property licensed to
us 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, we are 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 our material breach of the representations, warranties or covenants set forth in the
Cellectis Agreement, and Cellectis is required, subject to certain exceptions, to indemnify us 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, we have 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, we have 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 we have received regulatory approval. If we materially breach any of our
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. We have 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 us 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.

PREMISES, BUILDING, PROJECT, AND COMMON AREAS

1.1

Premises, Building, Project and Common Areas.

1.1.1

The Premises.    Landlord  hereby  leases  to  Tenant  and  Tenant  hereby  leases  from  Landlord  the  premises  set  forth  in
Section 2.2 of the Summary (the "Premises").  The outline of the Premises is set forth in Exhibit A attached hereto.  The outline of the "Building" and the
"Project," as those terms are defined in Section 1.1.2, are further depicted on the Site Plan attached hereto as Exhibit A.  The Parties agree that the lease of
the Premises is upon and subject to the terms, covenants and conditions herein set forth, and Tenant covenants as a material part of the consideration for this
Lease to keep and perform each and all of such terms, covenants and conditions by it to be kept and performed.  The Parties hereby acknowledge that the
purpose of Exhibit A is to show the approximate location of the Premises only, and such Exhibit is not meant to constitute an agreement, representation or
warranty  as  to  the  construction  of  the  Premises,  the  precise  area  thereof  or  the  specific  location  of  the  "Common  Areas,"  as  that  term  is  defined  in
Section 1.1.3, below, or the elements thereof or of the accessways to the Premises or the "Project," as that term is defined in Section 1.1.2, below, and that the
square footage of the Premises shall be as set forth in Section 2.1 of the Summary of Basic Lease Information.  Except as specifically set forth in this Lease
and  in  the  Tenant  Work  Letter  attached  hereto  as  Exhibit  B  (the  "Tenant  Work  Letter"),  Landlord  shall  not  be  obligated  to  provide  or  pay  for  any
improvement work or services related to the improvement of the Premises.  Tenant also acknowledges that neither Landlord nor any agent of Landlord has
made  any  representation  or  warranty  regarding  the  condition  of  the  Premises,  the  Building  or  the  Project  or  with  respect  to  the  suitability  of  any  of  the
foregoing for the conduct of Tenant's business, except as specifically set forth in this Lease and the Tenant Work Letter.  Landlord shall deliver the Premises
to Tenant fully decommissioned, in good, vacant, broom clean condition, and otherwise in substantially the same condition as of the date of this Lease, in
compliance with all laws, with the roof water-tight and in good working condition and with the plumbing, electrical systems, fire sprinkler system, elevator
system, lighting, air conditioning, heating, and all other building systems serving the Premises in good operating condition and repair, and with all required
occupancy  permits  (or  equivalent  final  permit  signoffs)  relating  to  the  Base  Building  (and  not  any  specific  Tenant  Improvements)  on  or  before  the  Rent
Commencement  Date.   The  laboratory  systems  serving  the  laboratory  portion  of  the  Premises  and  the  “Emergency  Generator”  (as  that  term  is  defined  in
Section 6.5 below) shall be delivered in their presently existing, as-is condition.  Notwithstanding anything in this Lease to the contrary, in connection with
the  foregoing  Landlord  shall,  at  Landlord's  sole  cost  and  expense  (which  shall  not  be  deemed  an  "Operating  Expense,"  as  that  term  is  defined  in  Section
4.2.4), repair or replace any failed or inoperable portion of the Building systems serving the Premises during the first two (2) years of the initial Lease term
("Warranty  Period"),  provided  that  the  need  to  repair  or  replace  was  not  caused  by  the  misuse,  misconduct,  damage,  destruction,  omissions,  and/or
negligence of Tenant, its subtenants and/or assignees, if any, or any company which is acquired, sold or merged with Tenant (collectively, "Tenant Damage"),
or  by  any  modifications,  Alterations  or  improvements  constructed  by  or  on  behalf  of  Tenant.    Landlord  shall  coordinate  such  work  with  Tenant  and  shall
utilize commercially reasonable efforts to perform the same in a manner designed to minimize interference with Tenant's use of the Premises.  To the extent
repairs which Landlord is required to make pursuant to this Section 1.1.1 are necessitated in part by Tenant Damage, then Tenant shall reimburse Landlord for
an equitable proportion of the cost of such repair. Landlord will be responsible for causing the exterior of the Building, the existing Building entrances, and all
exterior Common Areas (including required striping and handicapped spaces in the parking areas) to be in compliance with Applicable Laws, to the extent
required to allow the legal occupancy of the Premises or completion of the Tenant Improvements.

1.1.2

The  Building  and  The  Project.    The  Premises  constitutes  a  portion  of  the  building  set  forth  in  Section  2.1  of  the
Summary (the "Building").  The Building is part of an office/laboratory project currently known as "Edgewater Business Park."  The term "Project," as used
in  this  Lease,  shall  mean  (i)  the  Building  and  the  Common  Areas,  (ii)  the  land  (which  is  improved  with  landscaping,  parking  facilities  and  other
improvements) upon which the Building and the Common Areas are located, (iii) the other office/laboratory buildings located at Edgewater Business Park,
and  the  land  upon  which  such  adjacent  office/laboratory  buildings  are  located,  and  (iv)  at  Landlord's  discretion,  any  additional  real  property,  areas,  land,
buildings  or  other  improvements  added  thereto  outside  of  the  Project  (provided  that  any  such  additions  do  not  increase  Tenant's  obligations  under  this
Lease).  

subject to the rules and regulations referred to in Article 5, those portions of the Project

1.1.3

Common Areas.  Tenant shall have the non-exclusive right to use in common with other tenants in the Project, and

which are provided, from time to time, for use in common by Landlord, Tenant and any other tenants of the Project (such areas, together with such other
portions of the Project designated by Landlord, in its discretion, are collectively referred to herein as the "Common Areas").  Landlord shall maintain and
operate the Common Areas, including all sprinkler and other systems serving the Common Areas, in a first class manner, and the use thereof shall be subject
to  such  rules,  regulations  and  restrictions  as  Landlord  may  reasonably  make  from  time  to  time.    Landlord  reserves  the  right  to  close  temporarily,  make
alterations or additions to, or change the location of elements of the Project and the Common Areas, provided that such closures, alterations, additions or
changes  shall  not  unreasonably  interfere  with  Tenant’s  use  of  such  Common  Areas  and  provided,  further,  that  in  connection  therewith  Landlord  shall  use
commercially reasonable efforts to minimize any interference with Tenant's use of and access to the Premises and parking areas.  

1.2

Rentable Square Feet of Premises.  The rentable square footage of the Premises is hereby deemed to be as set forth in Section 2.2 of

the Summary, and shall not be subject to measurement or adjustment during the Lease Term.  

1.3

Right of First Offer.  Subject to the terms and conditions of this Section 1.3, Landlord hereby grants to the named Tenant in this
Lease (the "Original Tenant") and its "Permitted Assignees", as that term is defined in Section 14.8, below, a one-time right of first offer, during the initial
Lease Term only, with respect to the remaining rentable space in the Building not located within the Premises (the "First Offer Space").  Notwithstanding the
foregoing, such first offer right of Tenant shall commence only following the expiration or earlier termination of the existing leases of the First Offer Space
(including renewals of any such lease, irrespective of whether any such renewal is currently set forth in such lease or is subsequently granted or agreed upon,
and regardless of whether such renewal is consummated pursuant to a lease amendment or a new lease).  Such right of first offer shall be subordinate to all
rights of other tenants of the Project, which rights relate to the First Offer Space and are set forth in leases of space in the Project existing as of the date
hereof, including, without limitation, any expansion, first offer, first refusal, first negotiation and other rights, regardless of whether such rights are executed
strictly in accordance with their respective terms or pursuant to a lease amendment or a new lease (the "Superior Rights").  Notwithstanding any contrary
provision in the lease of any Superior Right Holder, such rights of any Superior Right Holder shall continue to be Superior Rights  in the event that such
Superior  Right  Holder's  lease  is  renewed  or  otherwise  modified  (and  irrespective  of  whether  any  such  renewal  is  currently  set  forth  in  such  lease  or  is
subsequently  granted  or  agreed  upon,  and  regardless  of  whether  such  renewal  is  consummated  pursuant  to  a  lease  amendment  or  a  new  lease).   All  such
tenants of the First Offer Space, and all such third party tenants in the Project holding Superior Rights, are collectively referred to as the "Superior Right
Holders".  Tenant's right of first offer shall be on the terms and conditions set forth in this Section 1.3.

1.3.1

Procedure for Offer.  Subject to the terms of this Section 1.3, Landlord shall notify Tenant (the "First Offer Notice")
from time to time when the First Offer Space or any portion thereof will become available for lease to third parties, subject to the rights of any Superior Right
Holder.  Pursuant to such First Offer Notice, Landlord shall offer to lease to Tenant the then available First Offer Space, and such First Offer Notice shall
include the base rent, allowance amounts if any, length of term, and other economic terms on which Landlord would be willing to lease the First Offer Space
to Tenant (the "Fundamental Terms").  The First Offer Notice shall describe the space so offered to Tenant and the base rent, and other fundamental material
economic terms upon which Landlord is willing to lease such space to Tenant.  

1.3.2

Procedure for Acceptance.  If Tenant wishes to exercise Tenant's right of first offer with respect to the space described
in  the  First  Offer  Notice,  then  within  seven  (7)  business  days  of  delivery  of  the  First  Offer  Notice  to  Tenant,  Tenant  shall  deliver  notice  to  Landlord  (the
"First Offer Exercise Notice") of Tenant's election to exercise its right of first offer with respect to the entire space described in the First Offer Notice on the
terms contained in such notice.  If Tenant does not so notify Landlord within such seven (7) business day period, then Landlord shall be free to lease the space
described in the First Offer Notice to anyone to whom Landlord desires on any terms Landlord desires; provided, that prior to entering a lease with a third
party tenant on economic terms which, on a net effective, present value basis, are more than 7% more favorable to the tenant than the terms contained in the
First Offer Notice, Landlord shall first deliver a revised First Offer Notice to Tenant on such more favorable terms in accordance with the procedure set forth
above.  Notwithstanding anything to the contrary contained herein, Tenant must elect to exercise its right of first offer, if at all, with respect to all of the space
offered by Landlord to Tenant at any particular time, and Tenant may not elect to lease only a portion thereof.

1.3.3

Construction  In  First  Offer  Space.     Unless  the  Fundamental  Terms  provided  to  Tenant  for  the  First  Offer  Space
otherwise specify, Tenant shall take the First Offer Space in its "as is" condition, and the construction of improvements in the First Offer Space shall comply
with the terms of Article 8 of this Lease. For the avoidance of doubt, if the Fundamental Terms include a tenant improvement allowance or a turn-key build
out, Tenant shall receive the same allowance or turn-key build out, as applicable.

1.3.4

Amendment to Lease.  If Tenant timely exercises Tenant's right to lease the First Offer Space as set forth herein, then
Landlord and Tenant shall within thirty (30) days thereafter execute an amendment to the Lease for such First Offer Space upon the terms and conditions as
set forth in the First Offer Notice and this Section 1.3.  The rentable square footage of any First Offer Space leased by Tenant shall be determined by Landlord
in accordance with Landlord's then current standard of measurement for the Building.  Tenant shall commence payment of rent for the First Offer Space, and
the term of Tenant's lease of the First Offer Space shall commence, upon the date set forth in the First Offer Notice (taking into consideration any applicable
construction period) (the "First Offer Commencement Date") and shall terminate on the date set forth in the First Offer Notice.

1.3.5

Termination of Right of First Offer.  Tenant's rights under this Section 1.3 shall be personal to the Original Tenant or
a Permitted Assignee and may only be exercised by the Original Tenant (and not any other assignee, sublessee or other transferee of the Original Tenant's
interest in the Lease) if the Original Tenant or a Permitted Assignee occupies not less than sixty-six percent (66%) of the Premises.  The right of first offer
granted herein shall terminate as to particular First Offer Space upon Tenant's failure to timely exercise its right of first offer with respect to such particular
First Offer Space.  Tenant shall not have the right to lease First Offer Space, as provided in this Section 1.3, if, as of the date of the attempted exercise of any
right of first offer by Tenant, or, at Landlord's option, as of the scheduled date of delivery of such First Offer Space to Tenant, Tenant is in default under the
Lease, or Tenant has previously been in default under the Lease more than twice during the Lease Term (beyond the expiration of any applicable notice and
cure period set forth in the Lease).

1.4

Delivery of the Premises.  Landlord shall deliver the Premises to Tenant in the condition required hereunder on or before November
1, 2018.  Following the full execution and delivery of this Lease by Landlord and Tenant and prior to November 1, 2018, Landlord shall allow Tenant access
to the Premises for the purpose of Tenant installing equipment or fixtures (including Tenant's data and telephone equipment) in the Premises.  Tenant shall
hold Landlord harmless from and indemnify, protect and defend Landlord against any loss or damage to the Building or Premises and against injury to any
persons caused by Tenant's actions pursuant to this Section 1.4.

1.5

Use of Existing IT Racks.   Tenant  shall  have  the  right,  at  no  additional  cost,  to  utilize  the  existing  IT  racks  in  the  Premises  and
Landlord agrees that Landlord shall not remove the same prior to delivery of the Premises to Tenant (the “Existing IT Racks”).  Landlord hereby makes no
representations or warranties regarding the condition of such Existing IT Racks, and Tenant accepts such Existing IT Racks in their currently existing, "as-is"
condition.  Landlord shall have no obligation to maintain or repair such Existing IT Racks.  Tenant hereby agrees that Tenant shall maintain and repair such
Existing IT Racks in good condition and repair throughout the term of the Lease, as hereby amended, at Tenant's sole cost and expense.  With respect to the
insurance which Tenant is obligated to maintain on its personal property during the term of the Lease pursuant to the terms and conditions of Section 10.3.2,
Tenant shall cause such insurance to also cover the Existing IT Racks.  Tenant shall not (i) remove any of the Existing IT Racks from the Premises, (ii) assign
the Existing IT Racks as collateral or otherwise, (iii) sell any of the Existing IT Racks, or (iv) give any third party a security interest or any other interest in
such Existing IT Racks.  Upon the expiration or earlier termination of the Lease, as hereby amended, Tenant shall promptly surrender such Existing IT Racks
to Landlord in good condition and repair, normal wear and tear excepted, at the Premises. .

2.2

Option Term.  

2.2.1

Option Right.  Landlord hereby grants to the Original Tenant and its "Permitted Assignees", as that term is defined in
Section  14.8,  below,  or  any  other  assignee  approved  by  Landlord  pursuant  to  the  terms  of  Section  14  below  (any  such  Permitted  Assignee  or  assignee
approved  by  Landlord  is  referred  to  as  an  “Approved Assignee”),  one  (1)  option  to  extend  the  Lease  Term  for  a  period  of  seven  (7)  years  (the  "Option
Term"), which option shall be irrevocably exercised only by written notice delivered by Tenant to Landlord not more than twelve (12) months nor less than
nine (9) months prior to the expiration of the initial Lease Term, provided that the following conditions (the "Option Conditions") are satisfied:  (i) as of the
date of delivery of such notice, Tenant is not in default under this Lease, after the expiration of any applicable notice and cure period; (ii) Tenant has not
previously been in default under this Lease, after the expiration of any applicable notice and cure period, more than twice in the twelve (12) month period
prior to the date of Tenant's attempted exercise; and (iii) the Lease then remains in full force and effect.  Landlord may, at Landlord's option, exercised in
Landlord's sole and absolute discretion, waive any of the Option Conditions in which case the option, if otherwise properly exercised by Tenant, shall remain
in full force and effect.  Upon the proper exercise of such option to extend, and provided that Tenant satisfies all of the Option Conditions (except those, if
any, which are waived by Landlord), the Lease Term, as it applies to the Premises, shall be extended for a period of seven (7) years.  The rights contained in
this Section 2.2 shall be personal to Original Tenant and any Approved Assignees, and may be exercised by Original Tenant or such Approved Assignees (and
not by any other assignee, sublessee or other "Transferee," as that term is defined in Section 14.1 of this Lease, of Tenant's interest in this Lease).

2.2.2

Option Rent.  The annual Rent payable by Tenant during the Option Term (the "Option Rent") shall be equal to the
"Fair Rental Value," as that term is defined below, for the Premises as of the commencement date of the Option Term.  The "Fair Rental Value," as used in
this Lease, shall be equal to the annual rent per rentable square foot (including additional rent and considering any "base year" or "expense stop" applicable
thereto), including all escalations, at which tenants (pursuant to leases consummated within the twelve (12) month period preceding the first day of the Option
Term),  are  leasing  non-sublease,  non-encumbered,  non-equity  space  that  is  not  significantly  greater  or  smaller  in  size  than  the  subject  space,  with  a
comparable level of improvements (excluding any property that Tenant would be allowed to remove from the Premises at the termination of this Lease), for a
comparable  lease  term,  in  an  arm's  length  transaction,  which  comparable  space  is  located  in  the  "Comparable  Buildings,"  as  that  term  is  defined  in  this
Section 2.2.2  (transactions  satisfying  the  foregoing  criteria  shall  be  known  as  the  "Comparable  Transactions"),  taking  into  consideration  the  following
concessions (the "Concessions"):  (a) rental abatement concessions, if any, being granted such tenants in connection with such comparable space; (b) tenant
improvements or allowances provided or to be provided for such comparable space, and taking into account the value, if any, of the existing improvements in
the subject space, such value to be based upon the age, condition, design, quality of finishes and layout of the improvements and the extent to which the same
can be utilized by a general office/lab user other than Tenant; and (c) other reasonable monetary concessions being granted such tenants in connection with
such comparable space.  The Concessions shall be reflected in the effective rental rate (which effective rental rate shall take into consideration the total dollar
value  of  such  Concessions  as  amortized  on  a  straight-line  basis  over  the  applicable  term  of  the  Comparable  Transaction  (in  which  case  such  Concessions
evidenced in the effective rental rate shall not be granted to Tenant)) payable by Tenant.  The term “Comparable Buildings” shall mean the Building and
those other life sciences buildings that are comparable to the Building in terms of age (based upon the date of completion of construction or major renovation
of to the building), quality of construction, level of services and amenities, size and appearance, and are located in South San Francisco, California and the
surrounding commercial area.

2.2.3

Determination of Option Rent.  In the event Tenant timely and appropriately exercises an option to extend the Lease
Term, Landlord shall notify Tenant of Landlord's determination of the Option Rent within thirty (30) days following Landlord’s receipt of Tenant’s exercise
notice.  If Tenant, on or before the date which is ten (10) business days following Landlord’s receipt of Tenant’s exercise notice, fails to accept or object to
Landlord’s determination of the Option Rent, Tenant’s right to extend this Lease pursuant to this Section 2.2 shall be of no further force or effect.  If Tenant,
on or before the date that is ten (10) business days following the date upon which Tenant receives Landlord's determination of the Option Rent, objects to
Landlord's determination of the Option Rent, then Landlord and Tenant shall attempt to agree upon the Option Rent using their best good-faith efforts.  If
Landlord and Tenant fail to reach agreement within ten (10) business days following Tenant's objection to the Option Rent (the "Outside Agreement Date"),
then Tenant shall have the right to withdraw its exercise of the option by

delivering  written  notice  thereof  to  Landlord  within  five  (5)  business  days  thereafter,  in  which  event  Tenant's  right  to  extend  this  Lease  pursuant  to  this
Section  2.2  shall  be  of  no  further  force  or  effect.    If  Tenant  does  not  withdraw  its  exercise  of  the  extension  option,  each  Party  shall  make  a  separate
determination  of  the  Option  Rent,  as  the  case  may  be,  within  ten  (10)  business  days  after  the  Outside  Agreement  Date,  and  such  determinations  shall  be
submitted to arbitration in accordance with Sections 2.2.3.1 through 2.2.3.7.  

2.2.3.1

Landlord and Tenant shall each appoint one arbitrator who shall be a real estate appraiser who shall have
been active over the five (5) year period ending on the date of such appointment in the appraisal of other class A life sciences buildings located in the South
San Francisco market area.  The determination of the arbitrators shall be limited solely to the issue of whether Landlord's or Tenant's submitted Option Rent is
the closest to the actual Option Rent, taking into account the requirements of Section 2.2.2, as determined by the arbitrators.  Each such arbitrator shall be
appointed within fifteen (15) days after the Outside Agreement Date.  Landlord and Tenant may consult with their selected arbitrators prior to appointment
and may select an arbitrator who is favorable to their respective positions.  The arbitrators so selected by Landlord and Tenant shall be deemed "Advocate
Arbitrators."

The two (2) Advocate Arbitrators so appointed shall be specifically required pursuant to an engagement
letter within ten (10) days of the date of the appointment of the last appointed Advocate Arbitrator to agree upon and appoint a third arbitrator ("Neutral
Arbitrator") who shall be qualified under the same criteria set forth hereinabove for qualification of the two Advocate Arbitrators, except that neither the
Landlord  or  Tenant  or  either  Parties’  Advocate  Arbitrator  may,  directly  or  indirectly,  consult  with  the  Neutral  Arbitrator  prior  or  subsequent  to  his  or  her
appearance.  The Neutral Arbitrator shall be retained via an engagement letter jointly prepared by Landlord's counsel and Tenant’s counsel.

2.2.3.2

decision as to whether the Parties shall use Landlord's or Tenant's submitted Option Rent, and shall notify Landlord and Tenant thereof.

2.2.3.3

The three arbitrators shall, within thirty (30) days of the appointment of the Neutral Arbitrator, reach a

2.2.3.4

The decision of the majority of the three arbitrators shall be binding upon Landlord and Tenant.  

If  either  Landlord  or  Tenant  fails  to  appoint  an  Advocate  Arbitrator  within  fifteen  (15)  days  after  the
Outside Agreement Date, then either Party may petition the presiding judge of the Superior Court of San Mateo County to appoint such Advocate Arbitrator
subject to the criteria in Section 2.2.3.1, or if he or she refuses to act, either Party may petition any judge having jurisdiction over the Parties to appoint such
Advocate Arbitrator.

2.2.3.5

If the two (2) Advocate Arbitrators fail to agree upon and appoint the Neutral Arbitrator, then either Party
may petition the presiding judge of the Superior Court of San Mateo County to appoint the Neutral Arbitrator, subject to criteria in Section 2.2.3.1, or if he or
she refuses to act, either Party may petition any judge having jurisdiction over the Parties to appoint such arbitrator.

2.2.3.6

2.2.3.7

The cost of the arbitration shall be paid by Landlord and Tenant equally.

In the event that the Option Rent shall not have been determined pursuant to the terms hereof prior to the
commencement  of  the  Option  Term,  Tenant  shall  be  required  to  pay  the  Option  Rent  initially  provided  by  Landlord  to  Tenant,  and  upon  the  final
determination of the Option Rent, the payments made by Tenant shall be reconciled with the actual amounts of Option Rent due, and the appropriate Party
shall make any corresponding payment to the other Party within thirty (30) days thereafter.

or if any payment of Rent is for a period that is shorter than one month, the Rent for any fractional month shall accrue on a daily basis for the period from the
date such payment is due to the end of such calendar month or to the end of the Lease Term at a rate per day that is equal to 1/365 of the applicable annual
Rent.  All other payments or adjustments required to be made under the terms of this Lease that require proration on a time basis shall be prorated on the same
basis.

4.2.5

Taxes.

4.2.5.1

"Tax  Expenses"  shall  mean  all  federal,  state,  county,  or  local  governmental  or  municipal  taxes,  fees,
charges  or  other  impositions  of  every  kind  and  nature,  whether  general,  special,  ordinary  or  extraordinary  (including,  without  limitation,  real  estate  taxes,
general and special assessments, transit taxes, leasehold taxes or taxes based upon the receipt of rent, including gross receipts or sales taxes applicable to the
receipt  of  rent,  unless  required  to  be  paid  by  Tenant,  personal  property  taxes  imposed  upon  the  fixtures,  machinery,  equipment,  apparatus,  systems  and
equipment, appurtenances, furniture and other personal property used in connection with the Project, or any portion thereof), that Landlord shall pay or accrue
during any Expense Year (without regard to any different fiscal year used by such governmental or municipal authority) because of or in connection with the
ownership, leasing and operation of the Project, or any portion thereof.

4.2.5.2

Tax Expenses shall include any:  (i) tax on the rent, right to rent or other income from the Project, or any
portion  thereof,  or  as  against  the  business  of  leasing  the  Project,  or  any  portion  thereof;  (ii)  assessment,  tax,  fee,  levy  or  charge  in  addition  to,  or  in
substitution, partially or totally, of any assessment, tax, fee, levy or charge previously included within the definition of real property tax; (iii) assessment, tax,
fee, levy, or charge allocable to or measured by the area of the Premises or the Rent payable hereunder, including any business or gross income tax or excise
tax with respect to the receipt of such rent, or upon or with respect to the possession, leasing, operating, management, maintenance, alteration, repair, use or
occupancy by Tenant of the Premises, or any portion thereof; and (iv) Any assessment, tax, fee, levy or charge, upon this transaction or any document to
which Tenant is a party, creating or transferring an interest or an estate in the Premises or the improvements thereon.

4.2.5.3

Any  reasonable  costs  and  expenses  (including  reasonable  attorneys'  and  consultants'  fees)  incurred  in
attempting to protest, reduce or minimize Tax Expenses shall be included in Tax Expenses in the Expense Year such expenses are incurred.  Tax refunds shall
be credited against Tax Expenses and refunded to Tenant regardless of when received, based on the Expense Year to which the refund is applicable, provided
that in no event shall the amount to be refunded to Tenant for any such Expense Year exceed the total amount paid by Tenant as Additional Rent under this
Article 4 for such Expense Year.  If Tax Expenses for any period during the Lease Term or any extension thereof are increased after payment thereof for any
reason,  including,  without  limitation,  error  or  reassessment  by  applicable  governmental  or  municipal  authorities,  Tenant  shall  pay  Landlord  upon  demand
Tenant's Share of any such increased Tax Expenses.  Notwithstanding anything to the contrary contained in this Section 4.2.5, there shall be excluded from
Tax Expenses (i) all excess profits taxes, franchise taxes, gift taxes, capital stock taxes, inheritance and succession taxes, transfer taxes, estate taxes, federal
and state income taxes, and other taxes to the extent applicable to Landlord's net income (as opposed to rents, receipts or income attributable to operations at
the Project), (ii) any items included as Operating Expenses, (iii) any items paid by Tenant under Section 4.5, (iv) assessments in excess of the amount that
would be payable if such assessment expense were paid in installments over the longest permitted term; (v) taxes imposed on land and improvements other
than the Project; (vi) tax increases resulting from the improvement of any of the Project for the sole use of other occupants; and (vii) any penalties or interest
thereon due to Landlord’s late or non-payment of any taxes.

At  Tenant's  request,  and  provided  that  it  is  then  deemed  advisable  by  Landlord  in  the  exercise  of
Landlord’s reasonable business judgment (i.e., Landlord has a reasonable expectation of success of such appeal), Landlord shall bring or cause to be brought
an application or proceeding for reduction of the assessed valuation of the Building or Project, as applicable, in order to reduce Tax Expenses.

4.2.5.4

4.2.6

"Tenant's Share" shall mean the percentage set forth in Section 6 of the Summary.  

4.3

Allocation of Direct Expenses.

The Parties acknowledge that the Building is a part of a multi-building project and that the
costs and expenses incurred in connection with the Project (i.e., the Direct Expenses) should be shared between the Building and the other buildings in the
Project.  Accordingly, as set forth in Section 4.2, Direct Expenses (which consist of Operating Expenses and Tax Expenses) are determined annually for the
Project  as  a  whole,  and  a  portion  of  the  Direct  Expenses,  which  portion  shall  be  determined  by  Landlord  on  an  equitable  basis,  shall  be  allocated  to  the
Building  (as  opposed  to  other  buildings  in  the  Project).    Such  portion  of  Direct  Expenses  allocated  to  the  Building  shall  include  all  Direct  Expenses
attributable solely to the Building and a pro rata portion of the Direct Expenses attributable to the Project as a whole, and shall not include Direct Expenses
attributable solely to other buildings in the Project.

4.4

Calculation and Payment of Additional Rent.  Commencing on the Rent Commencement Date, Tenant shall pay to Landlord, in

the manner set forth in Section 4.4.1, and as Additional Rent, Tenant's Share of Direct Expenses for each Expense Year during the Lease Term.

4.4.1

Statement of Actual Direct Expenses and Payment by Tenant.  Landlord shall give to Tenant within five (5) months
following  the  end  of  each  Expense  Year,  a  statement  (the  "Statement")  that  shall  reasonably  itemize  the  Direct  Expenses  incurred  or  accrued  for  such
preceding  Expense  Year,  and  that  shall  indicate  the  amount  of  Tenant's  Share  of  Direct  Expenses.    Upon  receipt  of  the  Statement  for  each  Expense  Year
commencing or ending during the Lease Term, Tenant shall pay, with its next installment of Base Rent due that is at least thirty (30) days thereafter, the full
amount  of  Tenant's  Share  of  Direct  Expenses  for  such  Expense  Year,  less  the  amounts,  if  any,  paid  during  such  Expense  Year  as  "Estimated  Direct
Expenses," as that term is defined in Section 4.4.2, below, and if Tenant paid more as Estimated Direct Expenses than the actual Tenant's Share of Direct
Expenses, Tenant shall receive a credit in the amount of Tenant's overpayment against Rent next due under this Lease.  The failure of Landlord to timely
furnish the Statement for any Expense Year shall not prejudice Landlord or Tenant from enforcing its rights under this Article 4.  Even though the Lease Term
has expired and Tenant has vacated the Premises, when the final determination is made of Tenant's Share of Direct Expenses for the Expense Year in which
this Lease terminates, Tenant shall pay to Landlord such amount within thirty (30) days, and if Tenant paid more as Estimated Direct Expenses than the actual
Tenant's  Share  of  Direct  Expenses,  Landlord  shall,  within  thirty  (30)  days,  deliver  a  check  payable  to  Tenant  in  the  amount  of  the  overpayment.    The
provisions of this Section 4.4.1 shall survive the expiration or earlier termination of the Lease Term.  Notwithstanding the immediately preceding sentence,
Tenant shall not be responsible for Tenant’s Share of any Direct Expenses attributable to any Expense Year that is first billed to Tenant more than two (2)
calendar  years  after  the  earlier  of  the  expiration  of  the  applicable  Expense  Year  or  the  Lease  Expiration  Date,  provided  that  in  any  event  Tenant  shall  be
responsible for Tenant’s Share of Direct Expenses levied by any governmental authority or by any public utility companies at any time following the Lease
Expiration  Date  that  is  attributable  to  any  Expense  Year  (provided  that  Landlord  delivers  Tenant  a  bill  for  such  amounts  within  two  (2)  years  following
Landlord’s receipt of the bill therefor).

4.4.2

Statement of Estimated Direct Expenses.  In addition, Landlord shall give Tenant a yearly expense estimate statement
(the "Estimate Statement") that shall set forth Landlord's reasonable estimate (the "Estimate") of what the total amount of Direct Expenses for the then-
current Expense Year shall be and the estimated Tenant's Share of Direct Expenses (the "Estimated Direct Expenses").  The failure of Landlord to timely
furnish the Estimate Statement for any Expense Year shall not preclude Landlord from enforcing its rights to collect any Estimated Direct Expenses under this
Article  4,  nor  shall  Landlord  be  prohibited  from  revising  any  Estimate  Statement  or  Estimated  Direct  Expenses  theretofore  delivered  to  the  extent
necessary.  Thereafter, Tenant shall pay, with its next installment of Base Rent due that is at least thirty (30) days thereafter, a fraction of the Estimated Direct
Expenses for the then-current Expense Year (reduced by any amounts paid pursuant to the last sentence of this Section 4.4.2).  Such fraction shall have as its
numerator  the  number  of  months  that  have  elapsed  in  such  current  Expense  Year,  including  the  month  of  such  payment,  and  twelve  (12)  as  its
denominator.  Until a new Estimate Statement is furnished (which Landlord shall have the right to deliver to Tenant at any time), Tenant shall pay monthly,
with  the  monthly  Base  Rent  installments,  an  amount  equal  to  one-twelfth  (1/12)  of  the  total  Estimated  Direct  Expenses  set  forth  in  the  previous  Estimate
Statement delivered by Landlord to Tenant.  

4.5

Taxes and Other Charges for Which Tenant Is Directly Responsible.

Tenant shall be liable for and shall pay ten (10) days
before delinquency, taxes levied against Tenant's equipment, furniture, fixtures and any other personal property located in or about the Premises.  If any such
taxes on Tenant's equipment, furniture, fixtures and any other personal property are levied against Landlord or Landlord's property or if the assessed value of
Landlord's  property  is  increased  by  the  inclusion  therein  of  a  value  placed  upon  such  equipment,  furniture,  fixtures  or  any  other  personal  property  and  if
Landlord pays the taxes based upon such increased assessment, which Landlord shall have the right to do regardless of the validity thereof but only under
proper  protest  if  requested  by  Tenant,  Tenant  shall  upon  demand  repay  to  Landlord  the  taxes  so  levied  against  Landlord  or  the  proportion  of  such  taxes
resulting from such increase in the assessment, as the case may be.

4.6

Landlord's Books and Records.  Within one hundred eighty (180) days after receipt by Tenant of a Statement, if Tenant disputes the
amount  of  Additional  Rent  set  forth  in  the  Statement,  a  member  of  Tenant's  finance  department,  or  an  independent  certified  public  accountant  (which
accountant is a member of a nationally recognized accounting firm and is not working on a contingency fee basis) ("Tenant's Accountant"), designated and
paid for by Tenant, may, after reasonable notice to Landlord and at reasonable times, inspect Landlord's records with respect to the Statement at Landlord's
offices, provided that there is no existing Event of Default and Tenant has paid all amounts required to be paid under the applicable Estimate Statement and
Statement, as the case may be.  In connection with such inspection, Tenant and Tenant's agents must agree in advance to follow Landlord's reasonable rules
and  procedures  regarding  inspections  of  Landlord's  records,  and  shall  execute  a  commercially  reasonable  confidentiality  agreement  regarding  such
inspection.  Tenant's failure to dispute the amount of Additional Rent set forth in any Statement within one hundred eighty (180) days of Tenant's receipt of
such Statement shall be deemed to be Tenant's approval of such Statement and Tenant, thereafter, waives the right or ability to dispute the amounts set forth in
such  Statement.    If  after  such  inspection,  Tenant  still  disputes  such  Additional  Rent,  a  determination  as  to  the  proper  amount  shall  be  made,  at  Tenant's
expense, by an independent certified public accountant (the "Accountant") selected by Landlord and subject to Tenant's reasonable approval; provided that if
such  Accountant  determines  that  Direct  Expenses  were  overstated  by  more  than  five  percent  (5%),  then  the  cost  of  the  Accountant  and  the  cost  of  such
determination  shall  be  paid  for  by  Landlord,  and  Landlord  shall  reimburse  Tenant  for  the  cost  of  Tenant's  Accountant  (provided  that  such  cost  shall  be  a
reasonable market cost for such services). Tenant hereby acknowledges that Tenant's sole right to inspect Landlord's books and records and to contest the
amount of Direct Expenses payable by Tenant shall be as set forth in this Section 4.6, and (except as set forth in the next succeeding sentence) Tenant hereby
waives  any  and  all  other  rights  pursuant  to  applicable  law  to  inspect  such  books  and  records  and/or  to  contest  the  amount  of  Direct  Expenses  payable  by
Tenant.

Prohibitions.  As a material inducement to Landlord to enter into this Lease with Tenant, Tenant has fully
and  accurately  completed  Landlord’s  Pre-Leasing  Environmental  Exposure  Questionnaire  (the  “Environmental  Questionnaire”),  which  is  attached  as
Exhibit E.  Tenant agrees that except for those chemicals or materials, and their approximate quantities listed on the Environmental Questionnaire (as the
same may be updated from time to time as provided below) or any similar chemicals or materials used for substantially the same purposes in substitution
thereof  in  compliance  with  applicable  law,  neither  Tenant  nor  Tenant’s  employees,  contractors  and  subcontractors  of  any  tier,  entities  with  a  contractual
relationship with Tenant (other than Landlord), or any entity acting as an agent or sub-agent of Tenant (collectively, "Tenant's Agents") will produce, use,
store or generate any "Hazardous Materials," as that term is defined below, on, under or about the Premises, nor cause any Hazardous Material to be brought
upon,  placed,  stored,  manufactured,  generated,  blended,  handled,  recycled,  used  or  "Released,"  as  that  term  is  defined  below,  on,  in,  under  or  about  the
Premises.    If  any  information  provided  to  Landlord  by  Tenant  on  the  Environmental  Questionnaire,  or  otherwise  relating  to  information  concerning
Hazardous  Materials  is  intentionally  false,  incomplete,  or  misleading  in  any  material  respect,  the  same  shall  be  deemed  a  default  by  Tenant  under  this
Lease.  Upon Landlord's request (but no more than once each Lease Year), or in the event of any material change in Tenant's use of Hazardous Materials in
the Premises, Tenant shall deliver to Landlord an updated Environmental Questionnaire.  Tenant shall notify Landlord prior to using any Hazardous Materials
in the Premises not described on the initial Environmental Questionnaire, and such use shall be subject to all of the provisions of this Lease.  Tenant shall not
install or permit Tenant's Agents to install any underground storage tank on the Premises.  For purposes of this Lease, "Hazardous Materials"  means  all
flammable  explosives,  petroleum  and  petroleum  products,  waste  oil,  radon,  radioactive  materials,  toxic  pollutants,  asbestos,  polychlorinated  biphenyls
(“PCBs”), medical waste, chemicals known to cause cancer or reproductive toxicity, pollutants, contaminants, hazardous wastes, toxic substances or related
materials, including without limitation any chemical, element, compound, mixture, solution, substance, object, waste or any combination thereof, that is or
may  be  hazardous  to  human  health,  safety  or  to  the  environment  due  to  its  radioactivity,  ignitability,  corrosiveness,  reactivity,  explosiveness,  toxicity,
carcinogenicity,  infectiousness  or  other  harmful  or  potentially  harmful  properties  or  effects,  or  defined  as,  regulated  as  or  included  in,  the  definition  of
“hazardous  substances,”  “hazardous  wastes,”  “hazardous  materials,”  or  “toxic  substances”  under  any  Environmental  Laws.    For  purposes  of  this  Lease,
"Release"  or  "Released"  or  "Releases"  shall  mean  any  release,  deposit,  discharge,  emission,  leaking,  spilling,  seeping,  migrating,  injecting,  pumping,
pouring, emptying, escaping, dumping, disposing, or other movement of Hazardous Materials into the environment.  Landlord acknowledges that Tenant will
be installing and using fume hoods in the Premises and that emissions of Hazardous Materials into the air in compliance with all Environmental Laws shall
not be considered Releases.

5.3.1.2

Notices to Landlord.  Tenant shall notify Landlord in writing as soon as possible but in no event later
than five (5) days after (i) the occurrence of any actual, alleged or threatened Release of any Hazardous Material in, on, under, from, about or in the vicinity
of the Premises (whether past or present), regardless of the source or quantity of any such Release, or (ii) Tenant becomes aware of any regulatory actions,
inquiries,  inspections,  investigations,  directives,  or  any  cleanup,  compliance,  enforcement  or  abatement  proceedings  (including  any  threatened  or
contemplated investigations or proceedings) relating to or potentially affecting the Premises, or (iii) Tenant becomes aware of any claims by any person or
entity  relating  to  any  Hazardous  Materials  in,  on,  under,  from,  about  or  in  the  vicinity  of  the  Premises,  whether  relating  to  damage,  contribution,  cost
recovery,  compensation,  loss  or  injury.    Collectively,  the  matters  set  forth  in  clauses  (i),  (ii)  and  (iii)  above  are  hereinafter  referred  to  as  “Hazardous
Materials Claims”.  Tenant shall promptly forward to Landlord copies of all orders, notices, permits, applications and other communications and reports in
connection with any Hazardous Materials Claims.  Additionally, Tenant shall promptly advise Landlord in writing of Tenant’s discovery of any occurrence or
condition on, in, under or about the Premises that could subject Tenant or Landlord to any liability, or restrictions on ownership, occupancy, transferability or
use  of  the  Premises  under  any  "Environmental  Laws,"  as  that  term  is  defined  below.    Tenant  shall  not  enter  into  any  legal  proceeding  or  other  action,
settlement, consent decree or other compromise with respect to any Hazardous Materials Claims without first notifying Landlord of Tenant’s intention to do
so and affording Landlord the opportunity to join and participate, as a party if Landlord so elects, in such proceedings and in no event shall Tenant enter into
any  agreements  that  are  binding  on  Landlord  or  the  Premises  without  Landlord’s  prior  written  consent.    Landlord  shall  have  the  right  to  appear  at  and
participate in, any and all legal or other administrative proceedings concerning any Hazardous Materials Claim.  For purposes of this Lease, “Environmental
Laws” means all applicable present and future laws relating to the protection of human health, safety, wildlife or the environment,

remediation, removal, or other clean-up (the “Clean-up”) of any Hazardous Materials is required, Tenant shall prepare and submit to Landlord within thirty
(30) days after receipt of the Environmental Report a comprehensive plan, subject to Landlord’s written approval, specifying the actions to be taken by Tenant
to perform the Clean-up so that the Premises are restored to the conditions required by this Lease.  Upon Landlord’s approval of the Clean-up plan, Tenant
shall, at Tenant’s sole cost and expense, without limitation on any rights and remedies of Landlord under this Lease, promptly implement such plan with a

then Landlord shall have the right, but not the obligation, and without waiving any other rights under this Lease, to carry out any Clean-up recommended by
the Environmental Report or required by any governmental authority having jurisdiction over the Premises, and recover all of the costs and expenses thereof
from Tenant as Additional Rent, payable within thirty (30) days after receipt of written demand therefor.

governmental  authority  confirming  that  the  Clean-up  has  been  completed  in  accordance  with  all  requirements  of  such  governmental  authority  and  that  no
further response action of any kind is required for the unrestricted use of the Premises (“Closure Letter”).  Upon the expiration or earlier termination of this
Lease, Tenant shall also be obligated to close all permits obtained in connection with Hazardous Materials used by Tenant or Tenant's Agents in accordance
with applicable laws.

Failure to Timely Clean-Up.  Should any Clean-up for which Tenant is responsible not be completed, or

the expiration or earlier termination of this Lease, then, commencing on the later of the termination of this Lease and three (3) business days after Landlord's
delivery  of  notice  of  such  failure  and  that  it  elects  to  treat  such  failure  as  a  holdover,  Tenant  shall  be  liable  to  Landlord  as  a  holdover  tenant  (as  more
particularly provided in Article 16) until Tenant has fully complied with its obligations under this Section 5.3.

5.3.4.4

regarding  the  environmental  condition  of  the  Premises  to  any  third  party  (other  than  Tenant’s  consultants,  attorneys,  property  managers,  employees,
shareholders and potential and actual investors, lenders, business and merger partners, subtenants and assignees that have a need to know such information),
including any governmental authority, without the prior written consent of Landlord.  In the event Tenant reasonably believes that disclosure is compelled by
applicable law, valid order of a court or judicial or administrative process, it shall, to the extent legally permitted, provide Landlord ten (10) days’ advance
notice of disclosure of confidential information so that Landlord may attempt to obtain a protective order.  Tenant may additionally release such information
to bona fide prospective purchasers or lenders, subject to any such parties’ written agreement to be bound by the terms of this Section 5.3.

5.3.6

Landlord’s  Obligations.    Unless  compelled  to  do  so  by  applicable  law,  valid  order  of  a  court  or  judicial  or

conclusions  or  reports  regarding  the  environmental  condition  of  the  Premises  (including  any  information,  data,  findings,  communications  or  conclusions
included in any Environmental Questionnaire) to any third party (other than Landlord’s consultants, attorneys, property managers, employees, shareholders
and potential and actual investors, lenders, business and merger partners, that have a need to know such information), including any governmental authority,
without the prior written consent of Tenant.  In the event Landlord reasonably believes that disclosure is compelled by applicable law, valid order of a court or
judicial  or  administrative  process,  it  shall,  to  the  extent  legally  permitted,  provide  Tenant  ten  (10)  days’  advance  notice  of  disclosure  of  confidential
information so that Tenant may attempt to obtain a protective order.  Landlord may additionally release such information to bona fide prospective purchasers
or lenders, subject to any such parties’ written agreement to be bound by the terms of this Section 5.3.

5.3.7

Copies of Environmental Reports.  Within thirty (30) days of receipt thereof, Tenant shall provide Landlord with a
copy of any and all environmental assessments, audits, studies and reports regarding Tenant’s activities with respect to the Premises, or ground water beneath
the Land, or the environmental condition or Clean-up thereof.  Tenant shall be obligated to provide Landlord with a copy of such materials without regard to
whether such materials are generated by Tenant or prepared for Tenant, or how Tenant comes into possession of such materials, unless doing so would result
in a breach of any contractual obligation of Tenant to a third party.

5.3.8

Signs,  Response  Plans,  Etc.    Tenant  shall  be  responsible  for  posting  on  the  Premises  any  signs  required  under
applicable  Environmental  Laws  with  respect  to  the  use  of  Hazardous  Materials  by  Tenant  or  Tenant's  Agents.    Tenant  shall  also  complete  and  file  any

SERVICES AND UTILITIES

6.1

In General.  Landlord will be responsible, at Tenant's sole cost and expense (subject to the terms of Section 4.2.4, above), for making
heating, ventilation and air‑conditioning, electricity, and water available to the Premises.  It is the Parties’ expectation that all utilities to the Premises will be
separately metered at the Premises and shall be paid directly by Tenant.  Landlord shall not provide janitorial, telephone services or interior security services
for the Premises.  Tenant shall be solely responsible for performing all janitorial services and other cleaning of the Premises, all in compliance with applicable
laws.  The janitorial and cleaning of the Premises shall be adequate to maintain the Premises in a manner consistent with First Class Life Sciences Projects.  

Tenant shall cooperate fully with Landlord at all times and abide by all reasonable regulations and requirements that Landlord may reasonably
prescribe  for  the  proper  functioning  and  protection  of  the  HVAC,  electrical,  mechanical  and  plumbing  systems.    Provided  that  Landlord  provides  and
maintains and keeps in continuous service utility connections to the Project, including electricity, gas, water and sewage connections, Landlord shall have no
obligation to provide any services or utilities to the Building, including heating, ventilation and air‑conditioning, electricity, water, telephone, janitorial and
interior Building security services, except as set forth in this Section 6.1.  

6.2

Tenant Payment of Utilities Costs.  It is the Parties’ expectation that all utilities (including electricity, gas, sewer and water) will be
separately  metered  or  sub-metered  to  the  Premises  and  will  be  paid  directly  by  Tenant.   After  the  Rent  Commencement  Date such  utilities  shall  either  be
contracted for and paid directly by Tenant to the applicable utility provider or, if, after the Rent Commencement Date, any utilities to the Building are not
separately metered to the Premises, then Tenant shall pay to Landlord, within thirty (30) days after billing, an equitable portion of the Building utility costs,
based on Tenant's proportionate use thereof.  In connection with the foregoing, Landlord shall install separate meters on the Building Systems as a part of
Landlord's  construction  of  the  Base  Building,  and  Tenant  shall  install  separate  meters  on  the  systems  installed  in  the  Premises  as  part  of  the  Tenant
Improvements pursuant to the Work Letter.

6.3

Interruption of Use.  Tenant agrees that Landlord shall not be liable for damages, by abatement of Rent or otherwise, for failure to
furnish  or  delay  in  furnishing  any  service  or  utility  (including  telephone  and  telecommunication  services,  UPS  services,  or  other  laboratory  services  or
utilities), or for any diminution in the quality or quantity thereof, when such failure or delay or diminution is occasioned, in whole or in part, by breakage,
repairs, replacements, or improvements, by any strike, lockout or other labor trouble, by inability to secure electricity, gas, water, or other fuel at the Building
or Project after reasonable effort to do so, by any riot or other dangerous condition, emergency, accident or casualty whatsoever, by act or default of Tenant or
other parties, or by any other cause; and such failures or delays or diminution shall never be deemed to constitute an eviction or disturbance of Tenant's use
and  possession  of  the  Premises  or  relieve  Tenant  from  paying  Rent  or  performing  any  of  its  obligations  under  this  Lease,  except  as  set  forth
below.  Notwithstanding the foregoing, Landlord shall be liable for damages to the extent caused by the negligence or willful misconduct of Landlord or the
Landlord Parties, provided that Landlord shall not be liable under any circumstances for injury to, or interference with, Tenant's business, including loss of
profits, however occurring, through or in connection with or incidental to a failure to furnish any of the services or utilities as set forth in this Article 6.

6.4

Energy  Performance  Disclosure  Information.    Tenant  hereby  acknowledges  that  Landlord  may  be  required  to  disclose  certain
information concerning the energy performance of the Building pursuant to California Public Resources Code Section 25402.10 and the regulations adopted
pursuant  thereto  (collectively  the  “Energy  Disclosure  Requirements”).    Tenant  hereby  acknowledges  prior  receipt  of  the  Data  Verification  Checklist,  as
defined  in  the  Energy  Disclosure  Requirements  (the  “Energy  Disclosure  Information”),  and  agrees  that  Landlord  has  timely  complied  in  full  with
Landlord’s obligations under the Energy Disclosure Requirements.  Tenant acknowledges and agrees that (i) Landlord makes no representation or warranty
regarding  the  energy  performance  of  the  Building  or  the  accuracy  or  completeness  of  the  Energy  Disclosure  Information,  (ii)  the  Energy  Disclosure
Information is for the current occupancy and use of the Building and that the energy performance of the Building may vary depending on future occupancy

omissions in the Energy Disclosure Information.  If and to the extent not prohibited by applicable laws, Tenant hereby waives any right Tenant may have to
receive  the  Energy  Disclosure  Information,  including  any  right  Tenant  may  have  to  terminate  this  Lease  as  a  result  of  Landlord’s  failure  to  disclose  such
information.  Further, Tenant hereby releases Landlord from any and all losses, costs, damages, expenses and/or liabilities relating to, arising out of and/or
resulting  from  the  Energy  Disclosure  Requirements,  including  any  liabilities  arising  as  a  result  of  Landlord’s  failure  to  disclose  the  Energy  Disclosure
Information to Tenant prior to the execution of this Lease.  Tenant’s acknowledgment of the AS-IS condition of the Premises pursuant to the terms of this
Lease shall be deemed to include the energy performance of the Building.  Tenant further acknowledges that pursuant to the Energy Disclosure Requirements,
Landlord may be required in the future to disclose information concerning Tenant’s energy usage to certain third parties, including prospective purchasers,
lenders and tenants of the Building (the “Tenant Energy Use Disclosure”).  Tenant hereby (A) consents to all such Tenant Energy Use Disclosures, and (B)
acknowledges that Landlord shall not be required to notify Tenant of any Tenant Energy Use Disclosure.  Further, Tenant hereby releases Landlord from any
and all losses, costs, damages, expenses and liabilities relating to, arising out of and/or resulting from any Tenant Energy Use Disclosure.  The terms of this
Section 6.3 shall survive the expiration or earlier termination of this Lease.

("Emergency Generator"), and Tenant shall have the right to connect to the Emergency Generator for up to Tenant's Share of the electrical capacity which is
available for use by tenants and provided by such Emergency Generator.  Tenant's use of the Emergency Generator shall be at Tenant's sole risk, and Tenant
acknowledges that neither Landlord nor any agent of Landlord has made any representation or warranty regarding the Emergency Generator.  Except to the
extent caused by the gross negligence or willful misconduct of Landlord, or any Landlord Parties, Tenant hereby waives any claims against Landlord or any
Landlord Parties resulting from Tenant's use of the Emergency Generator, or any failure of the Emergency Generator to operate as designed, and agrees that
Landlord shall not be liable for any damages resulting from any failure in operation of the Emergency Generator, including, without limitation any injury or
damage to, or interference with, Tenant's business, including but not limited to, loss of profits, loss of rents or other revenues, loss of business opportunity,
loss of goodwill or loss of use, or loss to equipment, inventory, scientific research, scientific experiments, laboratory animals, products, specimens, samples,

any painting, sealing, patching and waterproofing of exterior walls, and (5) repairs to the elevator in the Building and underground utilities, except  to  the
extent that any such repairs are required due to the negligence or willful misconduct of Tenant (the "Landlord Repair Obligations"); provided, however, that
if such repairs are due to the negligence or willful misconduct of Tenant, Landlord shall nevertheless make such repairs at Tenant's expense, or, if covered by
Landlord's  insurance,  Tenant  shall  only  be  obligated  to  pay  any  deductible  in  connection  therewith.    Costs  expended  by  Landlord  in  connection  with  the
Landlord  Repair  Obligations  shall  be  included  in  Operating  Expenses  to  the  extent  allowed  pursuant  to  the  terms  of  Article  4,  above.    Landlord  shall
cooperate with Tenant to enforce any warranties that Landlord holds that could reduce Tenant's maintenance obligations under this Lease.

8.

ADDITIONS AND ALTERATIONS

8.1

Landlord's Consent to Alterations.  Tenant may not make any improvements, alterations, additions or changes to the Premises or
any mechanical, plumbing or HVAC facilities or systems pertaining to the Premises (collectively, the "Alterations") without first procuring the prior written
consent of Landlord to such Alterations, which consent shall be requested by Tenant not less than ten (10) business  days prior to the commencement thereof,
and which consent shall not be unreasonably withheld, conditioned or delayed by Landlord, provided it shall be deemed reasonable for Landlord to withhold
its consent to any Alteration that adversely affects the structural portions or the systems or equipment of the Building or is visible from the exterior of the
Building.    Notwithstanding  the  foregoing,  Tenant  shall  be  permitted  to  make  Alterations  following  ten  (10)  business  days'  notice  to  Landlord  (as  to
Alterations costing more than $10,000 only), but without Landlord's prior consent, to the extent that such Alterations (i) do not affect the building systems or
equipment (other than minor changes such as adding or relocating electrical outlets and thermostats), (ii) are not visible from the exterior of the Building, and
(iii) cost less than $100,000.00 for a particular job of work.  The construction of the Tenant Improvements to the Premises shall be governed by the terms of
the Tenant Work Letter and not the terms of this Article 8.

8.2

Manner of Construction.  Landlord may impose, as a condition of its consent to any and all Alterations or repairs of the Premises or
about the Premises, such requirements as Landlord in its reasonable discretion may deem desirable, including, but not limited to, the requirement that upon
Landlord's  request,  Tenant  shall,  at  Tenant's  expense,  remove  such  Alterations  upon  the  expiration  or  any  early  termination  of  the  Lease  Term;  provided,
however,  that  Landlord  may  not  require  Tenant  to  remove  any  Alterations  which  are  otherwise  consistent  with  typical  tenant  improvements  in  the
biotechnology  or  pharmaceutical  industries.    Tenant  shall  construct  such  Alterations  and  perform  such  repairs  in  a  good  and  workmanlike  manner,  in
conformance with any and all applicable federal, state, county or municipal laws, rules and regulations and pursuant to a valid building permit, issued by the
city in which the Building is located (or other applicable governmental authority).    Tenant shall not use (and upon notice from Landlord shall cease using)
contractors, services, workmen, labor, materials or equipment that, in Landlord's reasonable judgment, would disturb labor harmony with the workforce or
trades engaged in performing other work, labor or services in or about the Building or the Common Areas.  Upon completion of any Alterations, Tenant shall
deliver to Landlord final lien waivers from all contractors, subcontractors and materialmen who performed such work.  In addition to Tenant's obligations
under Article 9, upon completion of any Alterations, Tenant agrees to cause a Notice of Completion to be recorded in the office of the Recorder of the County
of San Mateo in accordance with Section 3093 of the Civil Code of the State of California or any successor statute, and Tenant shall deliver to the Project
construction manager a reproducible copy of the "as built" drawings of the Alterations as well as all permits, approvals and other documents issued by any
governmental agency in connection with the Alterations.  

8.3

Payment for Improvements.  In connection with any Alterations that affect the Building systems (other than minor changes such as
adding or relocating electrical outlets and thermostats), or that have a cost in excess of $100,000, , Tenant shall reimburse Landlord for Landlord's reasonable,
actual, out-of-pocket costs and expenses actually incurred in connection with Landlord's review of such work.

8.4

Construction Insurance.  In addition to the requirements of Article 10, in the event that Tenant makes any Alterations, prior to the
commencement of such Alterations, Tenant shall provide Landlord with evidence that Tenant or Tenant's contractor carries "Builder's All Risk" insurance (to
the extent that the cost of such work shall exceed $50,000) in an amount approved by Landlord covering the construction of such Alterations, and such other
insurance as Landlord may reasonably require, it being understood and agreed that all of such Alterations shall be insured by Landlord pursuant to Article 10
immediately upon completion thereof.  In addition, Tenant's contractors and subcontractors shall be required to carry Commercial General Liability Insurance
in an amount approved by

Landlord and otherwise in accordance with the requirements of Article 10.  In connection with Alterations with a cost in excess of $250,000, Landlord may,
in its reasonable discretion, require Tenant to obtain a lien and completion bond or some alternate form of security satisfactory to Landlord in an amount
sufficient to ensure the lien-free completion of such Alterations and naming Landlord as a co-obligee.

8.5

Landlord's Property.  All Alterations, improvements, fixtures, equipment and/or appurtenances that may be installed or placed in or
about the Premises, from time to time, shall be at the sole cost of Tenant and all Alterations and improvements, shall be and become the property of Landlord
and remain in place at the Premises following the expiration or earlier termination of this Lease.  Notwithstanding the foregoing, Landlord may, by written
notice to Tenant given at the time it consents to an Alteration, require Tenant, at Tenant's expense, to remove any Alterations within the Premises and to repair
any  damage  to  the  Premises  and  Building  caused  by  such  removal;  provided,  however,  that  Landlord  may  not  require  Tenant  to  remove  any  Tenant
Improvements shown in the Final Working Drawings or any Alternations consistent with the improvements shown in the Final Working Drawings, or any
Alterations which are otherwise consistent with  typical tenant improvements in the biotechnology or pharmaceutical industries.  If Tenant fails to complete
such removal and/or to repair any damage caused by the removal of any Alterations, Landlord may do so and may charge the cost thereof to Tenant.  Tenant
hereby protects, defends, indemnifies and holds Landlord harmless from any liability, cost, obligation, expense or claim of lien in any manner relating to the
installation,  placement,  removal  or  financing  of  any  such  Alterations,  improvements,  fixtures  and/or  equipment  in,  on  or  about  the  Premises,  which
obligations of Tenant shall survive the expiration or earlier termination of this Lease.  Notwithstanding the foregoing, except to the extent the same are paid
for  by  the  Tenant  Improvement  Allowance,  the  items  set  forth  in  Exhibit G  attached  hereto  (the  "Tenant's  Property")  shall  at  all  times  be  and  remain
Tenant's property.  Exhibit G may be updated from time to time by agreement of the Parties.  Tenant may remove the Tenant's Property from the Premises at
any time, provided that Tenant repairs all damage caused by such removal.  Landlord shall have no lien or other interest in the Tenant's Property.

COVENANT AGAINST LIENS

Tenant shall keep the Project and Premises free from any liens or encumbrances arising out of the work

9.
performed, materials furnished or obligations incurred by or on behalf of Tenant, and shall protect, defend, indemnify and hold Landlord harmless from and
against any third party claims, liabilities, judgments or costs (including reasonable attorneys' fees and costs) arising out of same or in connection
therewith.  Except as to Alterations as to which no notice is required under the second sentence of Section 8.1, Tenant shall give Landlord notice at least ten
(10) business days prior to the commencement of any such work on the Premises (or such additional time as may be necessary under applicable laws) to
afford Landlord the opportunity of posting and recording appropriate notices of non-responsibility (to the extent applicable pursuant to then applicable
laws).  Tenant shall remove any such lien or encumbrance by bond or otherwise within ten (10) business days after notice by Landlord, and if Tenant shall fail
to do so, Landlord may pay the amount necessary to remove such lien or encumbrance, without being responsible for investigating the validity thereof.

10.

INSURANCE

10.1

Indemnification  and  Waiver.    Except  as  provided  in  Section 10.5  or  to  the  extent  due  to  the  negligence,  willful  misconduct  or
violation of this Lease by Landlord or the Landlord Parties, Tenant hereby assumes all risk of damage to property in, upon or about the Premises from any
cause whatsoever (including, but not limited to, any personal injuries resulting from a slip and fall in, upon or about the Premises) and agrees that Landlord,
its partners, subpartners and their respective officers, agents, servants, employees, and independent contractors (collectively, "Landlord Parties") shall not be
liable for, and are hereby released from any responsibility for, any damage either to person or property or resulting from the loss of use thereof, which damage
is sustained by Tenant or by other persons claiming through Tenant.  Tenant shall indemnify, defend, protect, and hold harmless the Landlord Parties from any
and all loss, cost, damage, expense and liability (including without limitation court costs and reasonable attorneys' fees) incurred in connection with or arising
from  any  cause  in,  on  or  about  the  Premises  (including,  but  not  limited  to,  a  slip  and  fall),  any  acts,  omissions  or  negligence  of  Tenant  or  of  any  person
claiming by, through or under Tenant, or of the contractors, agents, servants, employees, invitees, guests or licensees of Tenant or any such person, in, on or
about the Project or any breach of the terms of this Lease, either prior to, during, or after the expiration of the Lease Term, provided that the terms of the
foregoing  indemnity  and  release  shall  not  apply  to  the  negligence  or  willful  misconduct  of  Landlord  or  its  agents,  employees,  contractors,  licensees  or
invitees, or Landlord's violation of this Lease.  Should Landlord be named as a defendant in any suit brought against Tenant in connection with or arising out
of Tenant's occupancy of the Premises, Tenant shall pay to Landlord its costs and expenses incurred

in such suit, including its actual professional fees such as reasonable appraisers', accountants' and attorneys' fees.  Notwithstanding anything to the contrary in
this  Lease,  Landlord  shall  not  be  released  or  indemnified  from,  and  shall  indemnify,  defend,  protect  and  hold  harmless  Tenant,  its  agents  and  employees,
from,  all  losses,  damages,  liabilities,  demands,  claims,  actions,  attorneys’  fees,  costs  and  expenses  arising  from  the  negligence  or  willful  misconduct  of
Landlord or its agents, contractors, licensees or invitees, or a violation of Landlord’s obligations or representations under this Lease. The provisions of this
Section 10.1  shall  survive  the  expiration  or  sooner  termination  of  this  Lease  with  respect  to  any  claims  or  liability  arising  in  connection  with  any  event
occurring prior to such expiration or termination.

10.2

Tenant's Compliance With Landlord's Property Insurance.  Landlord shall insure the Building, Tenant Improvements and any
Alterations during the Lease Term against loss or damage under an "all risk" property insurance policy on a full replacement cost basis, with commercially
reasonable deductibles.  Such coverage shall be in such amounts, from such companies, and on such other terms and conditions, as Landlord may from time
to time reasonably determine.  Additionally, at the option of Landlord, such insurance coverage may include the risks of earthquakes and/or flood damage and
additional hazards, a rental loss endorsement and one or more loss payee endorsements in favor of the holders of any mortgages or deeds of trust encumbering
the  interest  of  Landlord  in  the  Building  or  the  ground  or  underlying  lessors  of  the  Building,  or  any  portion  thereof.   The  costs  of  such  insurance  shall  be
included in Operating Expenses, subject to the terms of Section 4.2.4.  Tenant shall, at Tenant's expense, comply with all insurance company requirements
pertaining to the use of the Premises.  If Tenant's conduct or use of the Premises causes any increase in the premium for such insurance policies then Tenant
shall reimburse Landlord for any such increase. Tenant, at Tenant's expense, shall comply with all rules, orders, regulations or requirements of the American
Insurance Association (formerly the National Board of Fire Underwriters) and with any similar body.  Notwithstanding anything to the contrary in this Lease,
Tenant  shall  not  be  required  to  comply  with  or  cause  the  Premises  to  comply  with  any  laws,  rules,  regulations  or  insurance  requirements  requiring  the
construction of alterations unless such compliance is necessitated solely due to Tenant's particular use of the Premises.  Landlord shall also keep in full force
and  effect  a  policy  of  Commercial  General  Liability  Insurance  protecting  Landlord  against  claims  for  bodily  injury  and  property  damage  arising  out  of
Landlord’s ownership, use, occupancy or maintenance of the Building and the Common Areas.  Such insurance shall be on an occurrence basis and shall
include limits of liability not less than those required of Tenant under Section 10.3.

10.3

Tenant's Insurance.  Tenant shall maintain the following coverages in the following amounts during the Lease Term (except Tenant

shall carry the insurance described in Section 10.3.1 during any period in which it enters the Premises).

Commercial General Liability Insurance on an occurrence form covering the insured against claims of bodily injury
and property damage (including loss of use thereof) arising out of Tenant's operations, and contractual liabilities including a contractual coverage for limits of
liability (which limits may be met together with umbrella liability insurance) of not less than:

10.3.1

10.3.2

Property Insurance covering all office furniture, business and trade fixtures, office and lab equipment, free-standing
cabinet work, movable partitions, merchandise and all other items of Tenant's property on the Premises installed by, for, or at the expense of Tenant.  Such

new without deduction for depreciation of the covered items and in amounts that meet any co-insurance clauses of the policies of insurance and shall include
coverage  for  damage  or  other  loss  caused  by  fire  or  other  peril  including,  but  not  limited  to,  vandalism  and  malicious  mischief,  theft,  water  damage
(excluding  flood),  including  sprinkler  leakage,  bursting  or  stoppage  of  pipes,  and  explosion,  and  providing  business  interruption  coverage  for  a  period  of

Tenant for actual direct or indirect loss of earnings attributable to the risks outlined in Section 10.3.2 above.

10.3.3

Business Income Interruption for ninety (90) days plus Extra Expense insurance in such amounts as will reimburse

Worker's Compensation and Employer's Liability or other similar insurance pursuant to all applicable state and local
statutes and regulations.  The policy shall include a waiver of subrogation in favor of Landlord, its employees, Lenders and any property manager or partners.

10.3.4

10.4

Form  of  Policies.    The  minimum  limits  of  policies  of  insurance  required  of  Tenant  under  this  Lease  shall  in  no  event  limit  the
liability of Tenant under this Lease.  Such insurance shall (i) name Landlord, its subsidiaries and affiliates, its property manager (if any) and any other party
the  Landlord  so  specifies,  as  an  additional  insured  on  the  liability  insurance,  including  Landlord's  managing  agent,  if  any;  (ii)  be  issued  by  an  insurance
company having a rating of not less than A-:VII in Best's Insurance Guide or that is otherwise acceptable to Landlord and authorized to do business in the
State  of  California;  and  (iv)  be  primary  insurance  as  to  all  claims  thereunder  and  provide  that  any  insurance  carried  by  Landlord  is  excess  and  is  non-
contributing with any insurance required of Tenant.  Tenant shall not cause said insurance to be canceled unless thirty (30) days' prior written notice shall have
been given to Landlord and any mortgagee of Landlord (unless such cancellation is the result of non-payment of premiums, in which case note less than five
(5) days' notice shall be provided).  Tenant shall deliver said policy or policies or certificates thereof to Landlord on or before the Rent Commencement Date
and at least ten (10) days before the expiration dates thereof.  In the event Tenant shall fail to procure such insurance, or to deliver such policies or certificate,
Landlord may, at its option, procure such policies for the account of Tenant, and the cost thereof shall be paid to Landlord within five (5) days after delivery
to Tenant of bills therefor.

10.5

Subrogation.  Landlord and Tenant hereby agree to look solely to, and seek recovery only from, their respective insurance carriers
in the event of a property or business interruption loss to the extent that such coverage is agreed to be provided hereunder, notwithstanding the negligence of
either Party.  Notwithstanding anything to the contrary in this Lease, the Parties each hereby waive all rights and claims against each other for such losses, and
waive all rights of subrogation of their respective insurers.  The Parties agree that their respective insurance policies do now, or shall, contain the waiver of
subrogation.

10.6

Additional  Insurance  Obligations.    Tenant  shall  carry  and  maintain  during  the  entire  Lease  Term,  at  Tenant's  sole  cost  and
expense,  increased  amounts  of  the  insurance  required  to  be  carried  by  Tenant  pursuant  to  this  Article  10  and  such  other  reasonable  types  of  insurance
coverage and in such reasonable amounts covering the Premises and Tenant's operations therein, as may be reasonably requested by Landlord or Landlord's
lender, but in no event in excess of the amounts and types of insurance then being required by landlords of buildings comparable to and in the vicinity of the
Building.

11.

DAMAGE AND DESTRUCTION

11.1

Repair of Damage to Premises by Landlord.  Tenant shall promptly notify Landlord of any damage to the Premises resulting from
fire or any other casualty.  If the Premises or any Common Areas serving or providing access to the Premises shall be damaged by fire or other casualty,
Landlord  shall  use  reasonable  efforts  to  notify  Tenant  within  sixty  (60)  days  after  the  date  of  discovery  of  the  damage  whether  Landlord  will  restore  the
Premises and Common Areas and, in Landlord’s reasonable judgment, the time period within which the restoration can be completed.   If Landlord elects to
restore Premises and Common Areas, Landlord shall promptly and diligently, subject to reasonable delays for insurance adjustment or other matters beyond
Landlord's reasonable control, and subject to all other terms of this Article 11, restore the Premises and such Common Areas.  Such restoration shall be to
substantially the same condition of the Premises and the Common Areas prior to the casualty, except for modifications required by zoning and building codes
and  other  laws  or  any  other  modifications  to  the  Common  Areas  deemed  desirable  by  Landlord,  which  are  consistent  with  the  character  of  the  Project,
provided that access to the Premises shall not be materially impaired and Landlord’s repair shall include the Tenant Improvements and Tenant’s Alterations
installed in the Premises.  Landlord shall not be liable for any inconvenience or annoyance to Tenant or its visitors, or injury to Tenant's business resulting in
any way from such damage or the repair thereof; provided however, that if such fire or other casualty shall have damaged the Premises or Common Areas
necessary to Tenant's occupancy, and the damaged portions of the Premises are not occupied by Tenant as a result thereof, then during the time and to the
extent the Premises are unfit for occupancy, the Rent shall be abated in proportion to the ratio that the amount of rentable square feet of the Premises which is
unfit for occupancy for the purposes permitted under this Lease bears to the total rentable square feet of the Premises.

11.2

Landlord's Option to Repair.    Notwithstanding  the  terms  of  Section 11.1,  Landlord  may  elect  not  to  rebuild  and/or  restore  the
Premises, Building and/or Project, and instead terminate this Lease, by notifying Tenant in writing of such termination within sixty (60) days after the date of
discovery of the damage, such notice to include a termination date giving Tenant sixty (60) days to vacate the Premises, but Landlord may so elect only if the
Building shall be damaged by fire or other casualty or cause, and one or more of the following conditions is present: (i) in Landlord's reasonable judgment,
repairs cannot reasonably be completed within one (1) year after the date of discovery of the damage (when such repairs are made without the payment of
overtime or other premiums); (ii) the damage is due to a risk that Landlord is not required to insure under this Lease, and the cost of restoration exceed five
percent (5%) of the replacement cost of the Building (unless Tenant agrees to pay any uninsured amount in excess of such five percent (5%)); or (iii) the
damage occurs during the last twelve (12) months of the Lease Term and will take more than sixty (60) days to restore.  

11.3

Tenant’s Option to Terminate.   Notwithstanding anything to the contrary in Section 11.1 or 11.2, if (a) the damage occurs during
the last twelve (12) months of the Lease Term, and will take more than sixty (60) days to restore, or (b) in the reasonable judgment of Landlord, the repairs
cannot be completed within eight (8) months days after the date of discovery of the damage (or are not in fact completed within nine (9) months after the date
of discovery of the damage), Tenant may elect, no earlier than sixty (60) days after the date of the damage and not later than ninety (90) days after the date of
such damage, or within thirty (30) days after such repairs are not timely completed, to terminate this Lease by written notice to Landlord effective as of the
date specified in the notice, which date shall not be less than thirty (30) days nor more than sixty (60) days after the date such notice is given by Tenant.  

11.4

Waiver of Statutory Provisions.  The provisions of this Lease, including this Article 11, constitute an express agreement between
Landlord and Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises, the Building or the Project, and any statute or
regulation  of  the  State  of  California,  including,  Sections  1932(2)  and  1933(4)  of  the  California  Civil  Code,  with  respect  to  any  rights  or  obligations
concerning damage or destruction in the absence of an express agreement between the Parties, and any other statute or regulation, now or hereafter in effect,
shall have no application to this Lease or any damage or destruction to all or any part of the Premises, the Building or the Project.

NONWAIVER

12.
No  provision  of  this  Lease  shall  be  deemed  waived  by  either  Party  unless  expressly  waived  in  a  writing  signed
thereby.  The waiver by either Party of any breach of any term, covenant or condition herein contained shall not be deemed to be a waiver of any subsequent
breach of same or any other term, covenant or condition herein contained.  The subsequent acceptance of Rent hereunder by Landlord shall not be deemed to
be a waiver of any preceding breach by Tenant of any term, covenant or condition of this Lease, other than the failure of Tenant to pay the particular Rent so
accepted, regardless of Landlord's knowledge of such preceding breach at the time of acceptance of such Rent.  No acceptance of a lesser amount than the
Rent herein stipulated shall be deemed a waiver of Landlord's right to receive the full amount due, nor shall any endorsement or statement on any check or
payment or any letter accompanying such check or payment be deemed an accord and satisfaction, and Landlord may accept such check or payment without
prejudice to Landlord's right to recover the full amount due.  No receipt of monies by Landlord from Tenant after the termination of this Lease shall in any
way alter the length of the Lease Term or of Tenant's right of possession hereunder, or after the giving of any notice shall reinstate, continue or extend the
Lease Term or affect any notice given Tenant prior to the receipt of such monies, it being agreed that after the service of notice or the commencement of a
suit, or after final judgment for possession of the Premises, Landlord may receive and collect any Rent due, and the payment of said Rent shall not waive or
affect said notice, suit or judgment.

CONDEMNATION

If the whole or any part of the Premises shall be taken by power of eminent domain or condemned by any

13.
competent authority for any public or quasi-public use or purpose, or if any adjacent property or street shall be so taken or condemned, or reconfigured or
vacated by such authority in such manner as to require the use or reconstruction of any part of the Premises, or if Landlord shall grant a deed or other
instrument in lieu of such taking by eminent domain or condemnation, Landlord shall have the option to terminate this Lease effective as of the date
possession is required to be surrendered to the authority.  If more than twenty percent (20%) of the rentable square feet of the Premises is taken, or if access to
the Premises is substantially impaired, in each case for a period in excess of one hundred eighty (180) days, Tenant shall have the option to terminate this
Lease effective as of the date possession is required to be surrendered to the authority.  Tenant shall not because of such taking assert any claim against
Landlord or the authority for any compensation because of such taking and Landlord shall be entitled to the entire award or payment in connection therewith,
except that Tenant shall have the right to

file any separate claim available to Tenant for any taking of Tenant's personal property and fixtures belonging to Tenant and removable by Tenant upon
expiration of the Lease Term pursuant to the terms of this Lease, for moving expenses, for the unamortized value of any improvements paid for by Tenant and
for the Lease “bonus value”, so long as such claims are payable separately to Tenant.  All Rent shall be apportioned as of the date of such termination.  If any
part of the Premises shall be taken, and this Lease shall not be so terminated, the Rent shall be proportionately abated.  Tenant hereby waives any and all
rights it might otherwise have pursuant to Section 1265.130 of The California Code of Civil Procedure.  Notwithstanding anything to the contrary contained
in this Article 13, in the event of a temporary taking of all or any portion of the Premises for a period of one hundred and eighty (180) days or less, then this
Lease shall not terminate but the Base Rent and the Additional Rent shall be abated for the period of such taking in proportion to the ratio that the amount of
rentable square feet of the Premises taken bears to the total rentable square feet of the Premises.  Landlord shall be entitled to receive the entire award made in
connection with any such temporary taking.

14.

ASSIGNMENT AND SUBLETTING

14.1

Transfers.   Tenant  shall  not,  without  the  prior  written  consent  of  Landlord,  assign,  mortgage,  pledge,  hypothecate,  encumber,  or
permit any lien to attach to, or otherwise transfer, this Lease or any interest hereunder, permit any assignment, or other transfer of this Lease or any interest
hereunder by operation of law, sublet the Premises or any part thereof, or enter into any license or concession agreements or otherwise permit the occupancy
or use of the Premises or any part thereof by any persons other than Tenant and its employees and contractors (all of the foregoing are hereinafter sometimes
referred  to  collectively  as  "Transfers"  and  any  person  to  whom  any  Transfer  is  made  or  sought  to  be  made  is  hereinafter  sometimes  referred  to  as  a
"Transferee").    If  Tenant  desires  Landlord's  consent  to  any  Transfer,  Tenant  shall  notify  Landlord  in  writing,  which  notice  (the  "Transfer Notice")  shall
include (i) the proposed effective date of the Transfer, which shall not be less than thirty (30) days nor more than one hundred eighty (180) days after the date
of delivery of the Transfer Notice, (ii) a description of the portion of the Premises to be transferred (the "Subject Space"), (iii) all of the terms of the proposed
Transfer and the consideration therefor, including calculation of the "Transfer Premium", as that term is defined in Section 14.3 below, in connection with
such  Transfer,  the  name  and  address  of  the  proposed  Transferee,  and  a  copy  of  all  existing  executed  and/or  proposed  documentation  pertaining  to  the
proposed Transfer, and (iv) current financial statements of the proposed Transferee certified by an officer, partner or owner thereof, and any other information
reasonably  required  by  Landlord  that  will  enable  Landlord  to  determine  the  financial  responsibility,  character,  and  reputation  of  the  proposed  Transferee,
nature of such Transferee's business and proposed use of the Subject Space.  Any Transfer made without Landlord's prior written consent shall, at Landlord's
option, be null, void and of no effect, and shall, at Landlord's option, constitute a default by Tenant under this Lease.  Whether or not Landlord consents to
any proposed Transfer, Tenant shall pay Landlord's reasonable review and processing fees, as well as any reasonable professional fees (including attorneys',
accountants',  architects',  engineers'  and  consultants'  fees)  incurred  by  Landlord  (not  to  exceed  $3,500  in  the  aggregate  for  any  particular  Transfer),  within
thirty (30) days after written request by Landlord.

14.2

Landlord's Consent.    Landlord  shall  not  unreasonably  withhold,  condition  or  delay  its  consent  to  any  proposed  Transfer  of  the
Subject Space to the Transferee on the terms specified in the Transfer Notice.  Without limitation as to other reasonable grounds for withholding consent, the
Parties hereby agree that it shall be reasonable under this Lease and under any applicable law for Landlord to withhold consent to any proposed Transfer
where one or more of the following apply:

14.2.1

The Transferee is of a character or reputation or engaged in a business which is not consistent with the quality of the

Building or the Project;

14.2.2

14.2.3

The Transferee is either a governmental agency or instrumentality thereof;

The Transferee is not a party of reasonable financial worth and/or financial stability in light of the responsibilities to

be undertaken in connection with the Transfer on the date consent is requested; or

14.2.4

The proposed Transfer would cause a violation of another lease for space in the Project, or would give an occupant of

the Project a right to cancel its lease.

If Landlord consents to any Transfer pursuant to the terms of this Section 14.2 (and does not exercise any recapture rights Landlord may have
under Section 14.4), Tenant may within six (6) months after Landlord's consent, but not later than the expiration of said six-month period, enter into such
Transfer of the Premises or portion thereof, upon substantially the same terms and conditions as are set forth in the Transfer Notice furnished by Tenant to
Landlord pursuant to Section 14.1, provided that if there are any changes in the terms and conditions from those specified in the Transfer Notice such that
Landlord would initially have been entitled to refuse its consent to such Transfer under this Section 14.2, Tenant shall again submit the Transfer to Landlord
for its approval and other action under this Article 14 (including Landlord's right of recapture, if any, under Section 14.4).  Notwithstanding anything to the
contrary in this Lease, if Tenant or any proposed Transferee claims that Landlord has unreasonably withheld or delayed its consent under Section 14.2  or
otherwise has breached or acted unreasonably under this Article 14, their sole remedies shall be a suit for contract damages (other than damages for injury to,
or  interference  with,  Tenant's  business  including  loss  of  profits,  however  occurring)  or  declaratory  judgment  and  an  injunction  for  the  relief  sought,  and
Tenant hereby waives all other remedies, including any right at law or equity to terminate this Lease, on its own behalf and, to the extent permitted under all
applicable laws, on behalf of the proposed Transferee.

14.3

Transfer Premium.  If Landlord consents to a Transfer, as a condition thereto, which the Parties hereby agree is reasonable, Tenant
shall  pay  to  Landlord  fifty  percent  (50%)  of  any  "Transfer  Premium,"  as  that  term  is  defined  in  this  Section  14.3,  received  by  Tenant  from  such
Transferee.  "Transfer Premium" shall mean all rent, additional rent or other consideration payable by such Transferee in connection with the Transfer in
excess of the Rent and Additional Rent payable by Tenant under this Lease during the term of the Transfer on a per rentable square foot basis if less than all
of the Premises is transferred, and after deduction of (i) any costs of improvements made to the Subject Space in connection with such Transfer, (ii) free rent
or rent abatement provided in connection with such Transfer, (iii) brokerage commissions paid in connection with such Transfer, and (iv) reasonable legal fees
incurred in connection with such Transfer, in each case amortized over the remaining Term of this Lease.  "Transfer Premium" shall also include, but not be
limited to, key money, bonus money or other cash consideration paid by Transferee to Tenant in connection with such Transfer, and any payment in excess of
fair market value for services rendered by Tenant to Transferee or for assets, fixtures, inventory, equipment, or furniture transferred by Tenant to Transferee in
connection with such Transfer.  The determination of the amount of Landlord's applicable share of the Transfer Premium shall be made on a monthly basis as
rent or other consideration is received by Tenant under the Transfer.  

14.4

Landlord's Option as to Subject Space.  Notwithstanding anything to the contrary contained in this Article 14, in the event Tenant
contemplates a Transfer other than to a Permitted Transferee that, together with all prior Transfers then remaining in effect, would cause fifty percent (50%)
or more of the Premises to be Transferred for more than fifty percent (50%) of the then remaining Lease Term (taking into account any extension of the Lease
Term  that  has  irrevocably  exercised  by  Tenant),  Tenant  shall  give  Landlord  notice  (the  "Intention  to  Transfer  Notice")  of  such  contemplated  Transfer
(whether  or  not  the  contemplated  Transferee  or  the  terms  of  such  contemplated  Transfer  have  been  determined).    The  Intention  to  Transfer  Notice  shall
specify  the  portion  of  and  amount  of  rentable  square  feet  of  the  Premises  which  Tenant  intends  to  Transfer  in  the  subject  Transfer  (the  "Contemplated
Transfer  Space"),  the  contemplated  date  of  commencement  of  the  Contemplated  Transfer  (the  "Contemplated  Effective  Date"),  and  the  contemplated
length of the term of such contemplated Transfer.  Thereafter, Landlord shall have the option, by giving written notice to Tenant within thirty (30) days after
receipt of any Intention to Transfer Notice, to recapture the Contemplated Transfer Space.  Such recapture shall cancel and terminate this Lease with respect
to such Contemplated Transfer Space as of the Contemplated Effective Date, and this Lease shall remain in effect with respect to the balance of the Premises
not so recaptured.  In the event of a recapture by Landlord, if this Lease shall be canceled with respect to less than the entire Premises, the Rent reserved
herein shall be prorated on the basis of the number of rentable square feet retained by Tenant in proportion to the number of rentable square feet contained in
the Premises, and this Lease as so amended shall continue thereafter in full force and effect, and upon request of either Party, the Parties shall execute written
confirmation of the same.  If Landlord declines, or fails to elect in a timely manner, to recapture such Contemplated Transfer Space under this Section 14.4,
then, subject to the other terms of this Article 14, for a period of nine (9) months (the "Nine Month Period") commencing on the last day of such thirty (30)
day period, Landlord shall not have any right to recapture the Contemplated Transfer Space with respect to any Transfer made during the Nine Month Period,
provided that any such Transfer is substantially on the terms set forth in the Intention to Transfer Notice, and provided further that any such Transfer shall be
subject to the remaining terms of this Article 14.  If such a Transfer is not so consummated within the Nine Month Period (or if a Transfer is so consummated,
then upon the expiration of the term of any Transfer of such Contemplated Transfer Space consummated within such Nine Month Period), Tenant shall again
be required to submit a new Intention to Transfer Notice to Landlord with respect any contemplated Transfer, as provided above in this Section 14.4.  Tenant
shall  not  be  required  to  provide  a  separate  Intention  to  Transfer  Notice  and  Tenant’s  request  for  Landlord’s  consent  to  a  Transfer  shall  satisfy  Tenant’s
obligations in this Section 14.4.

14.5

Effect of Transfer.  If Landlord consents to a Transfer, (i) the terms and conditions of this Lease shall in no way be deemed to have
been waived or modified, (ii) such consent shall not be deemed consent to any further Transfer by either Tenant or a Transferee, (iii) Tenant shall deliver to
Landlord, promptly after execution, an original executed copy of all documentation pertaining to the Transfer in form reasonably acceptable to Landlord, (iv)
Tenant shall furnish upon Landlord's request a complete statement, certified by an independent certified public accountant, or Tenant's chief financial officer,
setting forth in detail the computation of any Transfer Premium Tenant has derived and shall derive from such Transfer, and (v) no Transfer relating to this
Lease or agreement entered into with respect thereto, whether with or without Landlord's consent, shall relieve Tenant or any guarantor of this Lease from any
liability under this Lease, including in connection with the Subject Space.  Landlord or its authorized representatives shall have the right at all reasonable
times to audit the books, records and papers of Tenant relating to any Transfer, and shall have the right to make copies thereof.  If the Transfer Premium
respecting any Transfer shall be found understated, Tenant shall, within thirty (30) days after demand, pay the deficiency, and if understated by more than five
percent (5%), Tenant shall pay Landlord's costs of such audit.

14.6

Additional Transfers.  For purposes of this Lease, the term "Transfer" shall also include if Tenant is a partnership, the withdrawal
or  change,  voluntary,  involuntary  or  by  operation  of  law,  of  fifty  percent  (50%)  or  more  of  the  partners,  or  transfer  of  fifty  percent  (50%)  or  more  of
partnership interests, within a twelve (12)-month period, or the dissolution of the partnership without immediate reconstitution thereof.

14.7

Occurrence of Default.  Any Transfer hereunder shall be subordinate and subject to the provisions of this Lease, and if this Lease
shall be terminated during the term of any Transfer, Landlord shall have the right to:  (i) treat such Transfer as cancelled and repossess the Subject Space by
any lawful means, or (ii) require that such Transferee attorn to and recognize Landlord as its landlord under any such Transfer.  If Tenant shall be in default
under this Lease, Landlord is hereby irrevocably authorized, as Tenant's agent and attorney-in-fact, to direct any Transferee to make all payments under or in
connection with the Transfer directly to Landlord (which Landlord shall apply towards Tenant's obligations under this Lease) until such default is cured.  Such
Transferee shall rely on any representation by Landlord that Tenant is in default hereunder, without any need for confirmation thereof by Tenant.  Upon any
assignment,  the  assignee  shall  assume  in  writing  all  obligations  and  covenants  of  Tenant  thereafter  to  be  performed  or  observed  under  this  Lease.    No
collection  or  acceptance  of  rent  by  Landlord  from  any  Transferee  shall  be  deemed  a  waiver  of  any  provision  of  this  Article  14  or  the  approval  of  any
Transferee or a release of Tenant from any obligation under this Lease, whether theretofore or thereafter accruing.  In no event shall Landlord's enforcement
of any provision of this Lease against any Transferee be deemed a waiver of Landlord's right to enforce any term of this Lease against Tenant or any other
person.  If Tenant's obligations hereunder have been guaranteed, Landlord's consent to any Transfer shall not be effective unless the guarantor also consents to
such Transfer.

14.8

Non-Transfers.  Notwithstanding anything to the contrary contained in this Article 14, (i) an assignment or subletting of all or a
portion of the Premises to an affiliate of Tenant (an entity that is controlled by, controls, or is under common control with, Tenant), (ii) an assignment of the
Premises to an entity that acquires all or substantially all of the assets or interests (partnership, stock or other) of Tenant, or (iii) an assignment of the Premises
to  an  entity  that  is  the  resulting  entity  of  a  merger  or  consolidation  of  Tenant  with  another  entity  (collectively,  a  "Permitted Transferee"),  shall  not  be
deemed a Transfer under this Article 14 (and for the avoidance of doubt, Sections 14.2, 14.3 and 14.4. shall not apply to such Transfer), provided that (A)
Tenant  notifies  Landlord  of  any  such  assignment  or  sublease  and  promptly  supplies  Landlord  with  any  documents  or  information  requested  by  Landlord
regarding  such  assignment  or  sublease  or  such  affiliate,  (B)  such  assignment  or  sublease  is  not  a  subterfuge  by  Tenant  to  avoid  its  obligations  under  this
Lease, (C) such Permitted Transferee shall be of a character and reputation consistent with the quality of the Building, and (D) such  Permitted  Transferee
described in subpart (ii) or (iii) above shall have a tangible net worth (not including goodwill as an asset) computed in accordance with generally accepted
accounting principles ("Net Worth") at least equal to the Net Worth of Tenant on the day immediately preceding the effective date of such assignment or
sublease.  An assignee of Tenant's entire interest that is also a Permitted Transferee may also be known as a "Permitted Assignee".  "Control," as used in this
Section 14.8, shall mean the ownership, directly or indirectly, of at least fifty-one percent (51%) of the voting securities of, or possession of the right to vote,
in the ordinary direction of its affairs, of at least fifty-one percent (51%) of the voting interest in, any person or entity.  No such permitted assignment or
subletting shall serve to release Tenant from any of its obligations under this Lease.

14.9

Allowed Subleases.  Notwithstanding any contrary provision of this Article 14, Tenant shall have the right without the payment of a
Transfer Premium, and without the receipt of Landlord’s consent, but on prior notice to Landlord, to permit the occupancy of up to 3,000 square feet of the
Premises,  to  any  individual(s)  or  entities  with  an  ongoing  business  relationship  with  Tenant  (collectively,  "Tenant’s  Occupants")  on  and  subject  to  the
following conditions: (i) all such individuals or entities shall be of a character and reputation consistent with the quality of the Building and Project; (ii) no
individual or entity shall occupy a separately demised portion of the Premises or which contains an entrance to such portion of the Premises other than the
primary entrance to the Premises; and (iii) such occupancy shall not be a subterfuge by Tenant to avoid its obligations under this Lease or the restrictions on
Transfers pursuant to this Article 14.  Tenant shall promptly supply Landlord with any documents or information reasonably requested by Landlord regarding
any such individuals or entities.  Any occupancy permitted under this Section 14.9 shall not be deemed a Transfer under this Article 14.  Notwithstanding the
foregoing, no such occupancy shall relieve Tenant from any obligations or liability under this Lease.

15.

SURRENDER OF PREMISES; OWNERSHIP AND REMOVAL OF TRADE FIXTURES

15.1

Surrender of Premises.  No act or thing done by Landlord or any agent or employee of Landlord during the Lease Term shall be
deemed to constitute an acceptance by Landlord of a surrender of the Premises unless such intent is specifically acknowledged in writing by Landlord.  The
delivery of keys to the Premises to Landlord or any agent or employee of Landlord shall not constitute a surrender of the Premises or effect a termination of
this Lease, whether or not the keys are thereafter retained by Landlord, and notwithstanding such delivery Tenant shall be entitled to the return of such keys at
any reasonable time upon request until this Lease shall have been properly terminated.  The voluntary or other surrender of this Lease by Tenant, whether
accepted  by  Landlord  or  not,  or  a  mutual  termination  hereof,  shall  not  work  a  merger,  and  at  the  option  of  Landlord  shall  operate  as  an  assignment  to
Landlord of all subleases or subtenancies affecting the Premises or terminate any or all such sublessees or subtenancies.

15.2

Removal of Tenant Property by Tenant.  Upon the expiration of the Lease Term, or upon any earlier termination of this Lease,
Tenant shall, subject to the provisions of this Article 15, quit and surrender possession of the Premises to Landlord in as good order and condition as when
Tenant took possession and as thereafter improved by Landlord and/or Tenant, reasonable wear and tear, damage caused by casualty, repairs required as a
result of condemnation, and repairs that are specifically made the responsibility of Landlord hereunder excepted.  Upon such expiration or termination, Tenant
shall, without expense to Landlord, remove or cause to be removed from the Premises all debris and rubbish, and such items of furniture, equipment, free-
standing  cabinet  work,  movable  partitions  (but  not  demountable  walls)  and  other  articles  of  personal  property  owned  by  Tenant  or  installed  or  placed  by
Tenant at its expense in the Premises, and such similar articles of any other persons claiming under Tenant, as Landlord may, in its sole discretion, require to
be removed, and Tenant shall repair at its own expense all damage to the Premises and Building resulting from such removal.

15.3

Environmental Assessment.  In connection with its surrender of the Premises, Tenant shall submit to Landlord, at least fifteen (15)
days  prior  to  the  expiration  date  of  this  Lease  (or  in  the  event  of  an  earlier  termination  of  this  Lease,  as  soon  as  reasonably  possible  following  such
termination),  an  environmental  Assessment  of  the  Premises  by  a  competent  and  experienced  environmental  engineer  or  engineering  firm  reasonably
satisfactory  to  Landlord  (pursuant  to  a  contract  approved  by  Landlord  and  providing  that  Landlord  can  rely  on  the  Environmental  Assessment).    If  such
Environmental Assessment reveals that remediation or Clean-up is required under any Environmental Laws that Tenant is responsible for under this Lease,
Tenant shall submit a remediation plan prepared by a recognized environmental consultant and shall be responsible for all costs of remediation and Clean-up,
as more particularly provided in Section 5.3.

15.4

Condition  of  the  Building  and  Premises  Upon  Surrender.    In  addition  to  the  above  requirements  of  this  Article 15,  upon  the
expiration of the Lease Term, or upon any earlier termination of this Lease, Tenant shall, surrender the Premises and Building with Tenant having complied
with all of Tenant’s obligations under this Lease, including those relating to improvement, repair, maintenance, compliance with law, testing and other related
obligations of Tenant set forth in Article 7.  In the event that the Building and Premises shall be surrendered in a condition that does not comply with the
terms of this Section 15.4, because Tenant failed to comply with its obligations set forth in Lease, then following thirty (30) days' notice to Tenant, during
which thirty (30) day period Tenant shall have the right to cure such noncompliance, Landlord shall be entitled to expend all reasonable costs in order to cause
the same to comply with the required condition upon surrender and Tenant shall promptly reimburse Landlord for all such costs upon notice and, commencing
on the later of the termination of this Lease and three (3) business days after Landlord's delivery of notice of such failure and that it elects to treat such failure
as  a  holdover,  Tenant  shall  be  deemed  during  the  period  that  Tenant  or  Landlord,  as  the  case  may  be,  perform  obligations  relating  to  the  Surrender
Improvements to be in holdover under Article 16.

HOLDING OVER

If Tenant holds over after the expiration of the Lease Term or earlier termination thereof, with the express or implied
16.
consent  of  Landlord,  such  tenancy  shall  be  from  month-to-month  only,  and  shall  not  constitute  a  renewal  hereof  or  an  extension  for  any  further  term.    If
Tenant holds over after the expiration of the Lease Term of earlier termination thereof, without the express or implied consent of Landlord, such tenancy shall
be deemed to be a tenancy by sufferance only, and shall not constitute a renewal hereof or an extension for any further term.  In either case, Base Rent shall be
payable at a monthly rate equal to one hundred fifty percent (150%) of the Base Rent applicable during the last rental period of the Lease Term under this
Lease.  Such month-to-month tenancy or tenancy by sufferance, as the case may be, shall be subject to every other applicable term, covenant and agreement
contained herein.  Nothing contained in this Article 16  shall  be  construed  as  consent  by  Landlord  to  any  holding  over  by  Tenant,  and  Landlord  expressly
reserves the right to require Tenant to surrender possession of the Premises to Landlord as provided in this Lease upon the expiration or other termination of
this Lease.  The provisions of this Article 16 shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided herein or
at law.  If Tenant fails to surrender the Premises upon the termination or expiration of this Lease, in addition to any other liabilities to Landlord accruing
therefrom, Tenant shall protect, defend, indemnify and hold Landlord harmless from all loss, costs (including reasonable attorneys' fees) and liability resulting
from  such  failure,  including,  without  limiting  the  generality  of  the  foregoing,  any  claims  made  by  any  succeeding  tenant  founded  upon  such  failure  to
surrender and any lost profits to Landlord resulting therefrom.

ESTOPPEL  CERTIFICATES

Within  ten  (10)  business  days  following  a  request  in  writing  by  Landlord,  Tenant  shall  execute,
17.
acknowledge and deliver to Landlord an estoppel certificate, which, as submitted by Landlord, shall be substantially in the form of Exhibit D, attached hereto
(or such other form as may be reasonably required by any prospective mortgagee or purchaser of the Project, or any portion thereof), indicating therein any
exceptions  thereto  that  may  exist  at  that  time,  and  shall  also  contain  any  other  information  reasonably  requested  by  Landlord  or  Landlord's  mortgagee  or
prospective mortgagee.  Any such certificate may be relied upon by any prospective mortgagee or purchaser of all or any portion of the Project.  Tenant shall
execute and deliver whatever other instruments may be reasonably required for such purposes.  At any time during the Lease Term, in connection with a sale
or  financing  of  the  Building  by  Landlord,  Landlord  may  require  Tenant  to  provide  Landlord  with  its  most  recent  annual  financial  statement  and  annual
financial statements of the preceding two (2) years, if Tenant is not at the time of Landlord’s request publicly listed on a nationally-recognized stock exchange
or market.  Such statements shall be prepared in accordance with generally accepted accounting principles and, if such is the normal practice of Tenant, shall
be audited by an independent certified public accountant.  Landlord shall hold such statements confidential.  Failure of Tenant to timely execute, acknowledge
and deliver such estoppel certificate or other instruments shall constitute an acceptance of the Premises and an acknowledgment by Tenant that statements
included in the estoppel certificate are true and correct, without exception.

SUBORDINATION

18.
Landlord hereby represents and warrants to Tenant that the Project is not currently subject to any ground lease, or to
the lien of any mortgage or deed of trust.  This Lease shall be subject and subordinate to all future ground or underlying leases of the Building or Project and
to the lien of any mortgage, trust deed or other encumbrances now or hereafter in force against the Building or Project or any part thereof, if any, and to all
renewals, extensions, modifications, consolidations and replacements thereof, and to all advances made or hereafter to be made upon the security of such
mortgages  or  trust  deeds,  unless  the  holders  of  such  mortgages,  trust  deeds  or  other  encumbrances,  or  the  lessors  under  such  ground  lease  or  underlying
leases, require in writing that this Lease be superior thereto. The subordination of this Lease to any such future ground or underlying leases of the Building or
Project or to the lien of any mortgage, trust deed or other encumbrances, shall be subject to Tenant's receipt of a commercially reasonable subordination, non-
disturbance, and attornment agreement in favor of Tenant. Tenant covenants and agrees in the event any proceedings are brought for the foreclosure of any
such mortgage or deed in lieu thereof (or if any ground lease is terminated), to attorn, without any deductions or set-offs whatsoever, to the lienholder or
purchaser or any successors thereto upon any such foreclosure sale or deed in lieu thereof (or to the ground lessor), if so requested to do so by such purchaser
or  lienholder  or  ground  lessor,  and  to  recognize  such  purchaser  or  lienholder  or  ground  lessor  as  the  lessor  under  this  Lease,  provided  such  lienholder  or
purchaser  or  ground  lessor  shall  agree  to  accept  this  Lease  and  not  disturb  Tenant's  occupancy,  so  long  as  Tenant  timely  pays  the  rent  and  observes  and
performs the terms, covenants and conditions of this Lease to be observed and performed by Tenant.  Landlord's interest herein may be assigned as security at
any  time  to  any  lienholder.    Tenant  shall,  within  ten  (10)  days  of  request  by  Landlord,  execute  such  further  instruments  or  assurances  as  Landlord  may
reasonably  deem  necessary  to  evidence  or  confirm  the  subordination  or  superiority  of  this  Lease  to  any  such  mortgages,  trust  deeds,  ground  leases  or
underlying leases.  Tenant waives the provisions of any current or future statute, rule or law which may give or purport to give Tenant any right or election to
terminate or otherwise adversely affect this Lease and the obligations of the Tenant hereunder in the event of any foreclosure proceeding or sale.

DEFAULTS; REMEDIES

19.1

Events of Default.  The occurrence of any of the following shall constitute a default of this Lease by Tenant:

when due unless such failure is cured within five (5) business days after written notice; or

19.1.2

Except where a specific time period is otherwise set forth for Tenant's performance in this Lease, in which event the
failure to perform by Tenant within such time period shall be a default by Tenant under this Section 19.1.2, any failure by Tenant to observe or perform any
other provision, covenant or condition of this Lease to be observed or performed by Tenant where such failure continues for thirty (30) days after written
notice thereof from Landlord to Tenant; provided that if the nature of such default is such that the same cannot reasonably be cured within a thirty (30) day
period, Tenant shall not be deemed to be in default if it diligently commences such cure within such period and thereafter diligently proceeds to rectify and
cure such default; or

19.2

Remedies Upon Default.  Upon the occurrence and during the continuance of any event of default by Tenant, Landlord shall have,
in addition to any other remedies available to Landlord at law or in equity (all of which remedies shall be distinct, separate and cumulative), the option to
pursue any one or more of the following remedies, each and all of which shall be cumulative and nonexclusive, without any notice or demand whatsoever.

19.2.1

Terminate this Lease, in which event Tenant shall immediately surrender the Premises to Landlord, and if Tenant fails
to do so, Landlord may, without prejudice to any other remedy that it may have for possession or arrearages in rent, enter upon and take possession of the
Premises and expel or remove Tenant and any other person who may be occupying the Premises or any part thereof, without being liable for prosecution or
any claim or damages therefor; and Landlord may recover from Tenant the following:

(i)

(ii)

The worth at the time of award of the unpaid rent that has been earned at the time of such termination; plus

The  worth  at  the  time  of  award  of  the  amount  by  which  the  unpaid  rent  that  would  have  been  earned  after

termination until the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus

the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus

(iii)

The worth at the time of award of the amount by which the unpaid rent for the balance of the Lease Term after

(iv)

Any  other  amount  necessary  to  compensate  Landlord  for  all  the  detriment  proximately  caused  by  Tenant's
failure  to  perform  its  obligations  under  this  Lease  or  that  in  the  ordinary  course  of  things  would  be  likely  to  result  therefrom,  specifically
including, in each case to the extent allocable to the remaining Lease Term, brokerage commissions and advertising expenses incurred to obtain a
new tenant, expenses of remodeling the Premises or any portion thereof for a new tenant, whether for the same or a different use, and any special
concessions made to obtain a new tenant; and

The term "rent" as used in this Section 19.2 shall be deemed to be and to mean all sums of every nature required to be paid by Tenant pursuant to
the  terms  of  this  Lease,  whether  to  Landlord  or  to  others.   As  used  in  Sections 19.2.1(i)  and  (ii),  the  "worth  at  the  time  of  award"  shall  be  computed  by
allowing interest at the rate set forth in Article 25, but in no case greater than the maximum amount of such interest permitted by law.  As used in Section
19.2.1(iii),  the  "worth  at  the  time  of  award"  shall  be  computed  by  discounting  such  amount  at  the  discount  rate  of  the  Federal  Reserve  Bank  of  San
Francisco at the time of award plus one percent (1%).  

19.2.2

Landlord shall have the remedy described in California Civil Code Section 1951.4 (lessor may continue lease in effect
after  lessee's  breach  and  abandonment  and  recover  rent  as  it  becomes  due,  if  lessee  has  the  right  to  sublet  or  assign,  subject  only  to  reasonable
limitations).  Accordingly, if Landlord does not elect to terminate this Lease on account of any default by Tenant, Landlord may, from time to time, without
terminating this Lease, enforce all of its rights and remedies under this Lease, including the right to recover all rent as it becomes due.

19.2.3

Landlord shall at all times have the rights and remedies (which shall be cumulative with each other and cumulative
and in addition to those rights and remedies available under Sections 19.2.1 and 19.2.2, or any law or other provision of this Lease), without prior demand or
notice  except  as  required  by  applicable  law,  to  seek  any  declaratory,  injunctive  or  other  equitable  relief,  and  specifically  enforce  this  Lease,  or  restrain  or
enjoin a violation or breach of any provision hereof.  

19.3

Subleases of Tenant.  If Landlord elects to terminate this Lease on account of any default by Tenant, as set forth in this Article 19,
Landlord shall have the right to terminate any and all subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant
and affecting the Premises or may, in Landlord's sole discretion, succeed to Tenant's interest in such subleases, licenses, concessions or arrangements.  In the
event of Landlord's election to succeed to Tenant's interest in any such subleases, licenses, concessions or arrangements, Tenant shall, as of the date of notice
by Landlord of such election, have no further right to or interest in the rent or other consideration receivable thereunder.  

19.4

Efforts  to  Relet.    No  re-entry,  repairs,  maintenance,  changes,  alterations  and  additions,  appointment  of  a  receiver  to  protect
Landlord's interests hereunder, or any other action or omission by Landlord shall be construed as an election by Landlord to terminate this Lease or Tenant's
right to possession, or to accept a surrender of the Premises, nor shall same operate to release Tenant in whole or in part from any of Tenant's obligations
hereunder, unless express written notice of such intention is sent by Landlord to Tenant.  

19.5

Landlord Default.

19.5.1

General.    Notwithstanding  anything  to  the  contrary  set  forth  in  this  Lease,  Landlord  shall  not  be  in  default  in  the
performance of any obligation required to be performed by Landlord pursuant to this Lease unless Landlord fails to perform such obligation within thirty (30)
days after the receipt of notice from Tenant specifying in detail Landlord's failure to perform; provided, however, if the nature of Landlord's obligation is such
that more than thirty (30) days are required for its performance, then Landlord shall not be in default under this Lease if it shall commence such performance
within such thirty (30) day period and thereafter diligently pursue the same to completion.  Upon any such default by Landlord under this Lease, Tenant may,
except as otherwise specifically provided in this Lease to the contrary, exercise any of its rights provided at law or in equity.

19.5.2

Abatement of Rent.  In the event that Tenant is prevented from using, and does not use, the Premises or any portion
thereof, as a result of (i) any repair, maintenance or alteration performed by Landlord, or which Landlord failed to perform, after the Rent Commencement
Date and required by this Lease, or (ii) any failure to provide services, utilities or access to the Premises as required by this Lease, each as a direct result of
Landlord's,  negligence  or  willful  misconduct  or  breach  of  this  Lease  (and  except  to  the  extent  such  failure  is  caused  in  whole  or  in  part  by  the  action  or
inaction of Tenant) (any such set of circumstances as set forth in items (i) or (ii), above, to be known as an "Abatement Event"),  then  Tenant  shall  give
Landlord notice of such Abatement Event, and if such Abatement Event continues for five (5) consecutive business days after Landlord's receipt of any such
notice (the "Eligibility Period"), then the Base Rent, Tenant's Share of Direct Expenses, and Tenant's obligation, if any, to pay for parking (to the extent not
utilized  by  Tenant)  shall  be  abated  or  reduced,  as  the  case  may  be,  after  expiration  of  the  Eligibility  Period  for  such  time  that  Tenant  continues  to  be  so
prevented from using, and does not use for the normal conduct of Tenant's business, the Premises or a portion thereof, in the proportion that the rentable area
of the portion

of the Premises that Tenant is prevented from using, and does not use, bears to the total rentable area of the Premises; provided, however, in the event that
Tenant is prevented from using, and does not use, a portion of the Premises for a period of time in excess of the Eligibility Period and the remaining portion of
the Premises is not sufficient to allow Tenant to effectively conduct its business therein, and if Tenant does not effectively conduct its business from such
remaining portion, then for such time after expiration of the Eligibility Period during which Tenant is so prevented from effectively conducting its business
therein, the Base Rent and Tenant's Share of Direct Expenses for the entire Premises and Tenant's obligation to pay for parking shall be abated for such time
as Tenant continues to be so prevented from using, and does not use, the Premises.  If, however, Tenant reoccupies any portion of the Premises during such
period, the Rent allocable to such reoccupied portion, based on the proportion that the rentable area of such reoccupied portion of the Premises bears to the
total rentable area of the Premises, shall be payable by Tenant from the date Tenant reoccupies such portion of the Premises.  To the extent an Abatement
Event is caused by an event covered by Articles 5, 11 or 13 of this Lease, then Tenant's right to abate rent shall be governed by the terms of such Article 5, 11
or 13, as applicable, and the Eligibility Period shall not be applicable thereto.  Except as provided in this Section 19.5.2, nothing contained herein shall be
interpreted to mean that Tenant is excused from paying Rent due hereunder.

COVENANT OF QUIET ENJOYMENT

20.
Landlord covenants that Tenant, on paying the Rent, charges for services and other payments
herein reserved and on keeping, observing and performing all the other terms, covenants, conditions, provisions and agreements herein contained on the part
of Tenant to be kept, observed and performed, within  the  notice  and  cure  periods  provided  for  in  this  Lease,  shall, during the Lease Term, peaceably and
quietly have, hold and enjoy the Premises subject to the terms, covenants, conditions, provisions and agreements hereof without interference by any persons
lawfully claiming by or through Landlord.  The foregoing covenant is in lieu of any other covenant express or implied.

21.

LETTER OF CREDIT

21.1

Delivery  of  Letter  of  Credit.    Tenant  shall  deliver  to  Landlord,  concurrently  with  Tenant's  execution  of  this  Lease,  an
unconditional, clean, irrevocable letter of credit (the "L‑C") in the amount set forth in Section 8 of the Lease Summary (the "L‑C Amount"), which L‑C shall
be issued by a money-center, solvent and nationally recognized bank (a bank that accepts deposits, maintains accounts, has a local San Francisco Bay Area
office that will negotiate a letter of credit, and whose deposits are insured by the FDIC) reasonably acceptable to Landlord (such approved, issuing bank being
referred to herein as the "Bank"), which Bank must have a rating from Standard and Poors Corporation of A- or better (or any equivalent rating thereto from
any  successor  or  substitute  rating  service  selected  by  Landlord)  and  a  letter  of  credit  issuer  rating  from  Moody’s  Investor  Service  of  A3  or  better  (or  any
equivalent rating thereto from any successor rating agency thereto)) (collectively, the “Bank’s Credit Rating Threshold”), and which L‑C shall be in a form
reasonably approved by Landlord.  Tenant shall pay all expenses, points and/or fees incurred by Tenant in obtaining the L‑C.  The L‑C shall (i) be "callable"
at sight, irrevocable and unconditional, (ii) be maintained in effect, whether through renewal or extension, for the period commencing on the Execution Date
and continuing until the date (the "L‑C Expiration Date")  that  is  no  less  than  sixty  (60)  days  after  the  expiration  of  the  Lease  Term  as  the  same  may  be
extended, and Tenant shall deliver a new L‑C or certificate of renewal or extension to Landlord at least thirty (30) days prior to the expiration of the L‑C then
held by Landlord, without any action whatsoever on the part of Landlord, (iii) be fully assignable by Landlord, its successors and assigns, (iv) permit partial
draws and multiple presentations and drawings, and (v) be otherwise subject to the Uniform Customs and Practices for Documentary Credits (1993-Rev),
International  Chamber  of  Commerce  Publication  #500,  or  the  International  Standby  Practices-ISP  98,  International  Chamber  of  Commerce  Publication
#590.    Landlord  shall  have  the  right  to  draw  down  an  amount  up  to  the  face  amount  of  the  L‑C  if  any  of  the  following  shall  have  occurred  or  be
applicable:  (A)  such amount is due to Landlord under the terms and conditions of this Lease, and has not been paid within applicable notice and cure periods
(or, if Landlord is prevented by law from providing notice, within the period for payment set forth in this Lease, plus applicable cure periods, assuming that
notice  is  deemed  delivered  on  the  first  business  day  following  the  expiration  of  the  period  for  payment  set  forth  in  this  Lease),  or  (B)  Tenant  has  filed  a
voluntary petition under the U. S. Bankruptcy Code or any state bankruptcy code (collectively, "Bankruptcy Code"), or (C) an involuntary petition has been
filed against Tenant under the Bankruptcy Code that is not dismissed within thirty (30) days, or (D) this Lease has been rejected, or is deemed rejected, under
Section 365 of the U.S. Bankruptcy Code, following the filing of a voluntary petition by Tenant under the Bankruptcy Code, or the filing of an involuntary
petition  against  Tenant  under  the  Bankruptcy  Code,  or  (E)  the  Bank  has  notified  Landlord  that  the  L‑C  will  not  be  renewed  or  extended  through  the  L‑C
Expiration Date, and Tenant has not provided a replacement L-C that satisfies

the  requirements  of  this  Lease  at  least  thirty  (30)  days  prior  to  such  expiration,  or  (F)  Tenant  is  placed  into  receivership  or  conservatorship,  or  becomes
subject to similar proceedings under Federal or State law, or (G) Tenant executes an assignment for the benefit of creditors, or (H) if (1) any of the Bank's
Fitch  Ratings  (or  other  comparable  ratings  to  the  extent  the  Fitch  Ratings  are  no  longer  available)  have  been  reduced  below  the  Bank's  Credit  Rating
Threshold,  or  (2)  there  is  otherwise  a  material  adverse  change  in  the  financial  condition  of  the  Bank,  and  Tenant  has  failed  to  provide  Landlord  with  a
replacement letter of credit, conforming in all respects to the requirements of this Article 21 (including the requirements placed on the issuing Bank more
particularly set forth in this Section 21.1), in the amount of the applicable L‑C Amount, within ten (10) business days following Landlord’s written demand
therefor (with no other notice or cure or grace period being applicable thereto, notwithstanding anything in this Lease to the contrary) (each of the foregoing
being an "L‑C  Draw  Event").  The L‑C  shall  be  honored  by  the  Bank  regardless  of  whether  Tenant  disputes  Landlord's  right  to  draw  upon  the  L‑C.    In
addition, in the event the Bank is placed into receivership or conservatorship by the Federal Deposit Insurance Corporation or any successor or similar entity,
then, effective as of the date such receivership or conservatorship occurs, said L‑C shall be deemed to fail to meet the requirements of this Article 21, and,
within ten (10) business days following Landlord's notice to Tenant of such receivership or conservatorship (the "L‑C FDIC Replacement Notice"), Tenant
shall replace such L‑C with a substitute letter of credit from a different issuer (which issuer shall meet or exceed the Bank's Credit Rating Threshold and shall
otherwise be acceptable to Landlord in its reasonable discretion) and that complies in all respects with the requirements of this Article 21.  If Tenant fails to
replace such L‑C with such conforming, substitute letter of credit pursuant to the terms and conditions of this Section 21.1, then, notwithstanding anything in
this Lease to the contrary, Landlord shall have the right to declare Tenant in default of this Lease for which there shall be no notice or grace or cure periods
being  applicable  thereto  (other  than  the  aforesaid  ten  (10) business  day  period).   Tenant  shall  be  responsible  for  the  payment  of  any  and  all  Tenant’s  and
Bank’s costs incurred with the review of any replacement L‑C, which replacement is required pursuant to this Section or is otherwise requested by Tenant.  In
the  event  of  an  assignment  by  Tenant  of  its  interest  in  this  Lease  (and  irrespective  of  whether  Landlord's  consent  is  required  for  such  assignment),  the
acceptance of any replacement or substitute  letter of credit by Landlord from the assignee shall be subject to Landlord's prior written approval, in Landlord's
reasonable discretion, and the actual and reasonable attorney's fees incurred by Landlord in connection with such determination shall be payable by Tenant to
Landlord within thirty (30) days of billing.

21.2

Application of L‑C.  Tenant hereby acknowledges and agrees that Landlord is entering into this Lease in material reliance upon the
ability of Landlord to draw upon the L‑C upon the occurrence of any L‑C Draw Event.  In the event of any L‑C Draw Event, Landlord may, but without
obligation to do so, and without notice to Tenant (except in connection with an L-C Draw Event under Section 21.1(H)), draw upon the L‑C, in part or in
whole, in the amount necessary to cure any such L-C Draw Event and/or to compensate Landlord for any and all damages of any kind or nature sustained or
that Landlord reasonably estimates that it will sustain resulting from Tenant's default of this Lease or other L-C Draw Event and/or to compensate Landlord
for any and all damages arising out of, or incurred in connection with, the termination of this Lease, including, without limitation, those specifically identified
in Section 1951.2 of the California Civil Code.  The use, application or retention of the L‑C, or any portion thereof, by Landlord shall not prevent Landlord
from  exercising  any  other  right  or  remedy  provided  by  this  Lease  or  by  any  applicable  law,  it  being  intended  that  Landlord  shall  not  first  be  required  to
proceed against the L‑C, and such L‑C shall not operate as a limitation on any recovery to which Landlord may otherwise be entitled.  Tenant agrees and
acknowledges that (i) the L‑C constitutes a separate and independent contract between Landlord and the Bank, (ii) Tenant is not a third party beneficiary of
such contract, (iii) Tenant has no property interest whatsoever in the L‑C or the proceeds thereof, and (iv) in the event Tenant becomes a debtor under any
chapter  of  the  Bankruptcy  Code,  Tenant  is  placed  into  receivership  or  conservatorship,  and/or  there  is  an  event  of  a  receivership,  conservatorship  or  a
bankruptcy filing by, or on behalf of, Tenant, neither Tenant, any trustee, nor Tenant's bankruptcy estate shall have any right to restrict or limit Landlord's
claim and/or rights to the L‑C and/or the proceeds thereof by application of Section 502(b)(6) of the U. S. Bankruptcy Code or otherwise.

21.3

Maintenance of L-C by Tenant.  If, as a result of any drawing by Landlord of all or any portion of the L-C, the amount of the L-C
shall be less than the L-C Amount, Tenant shall, within ten (10) business days thereafter, provide Landlord with additional letter(s) of credit in an amount
equal to the deficiency, and any such additional letter(s) of credit shall comply with all of the provisions of this Article 21.   Tenant  further  covenants  and
warrants that it will neither assign nor encumber the L-C or any part thereof and that neither Landlord nor its successors or assigns will be bound by any such
assignment, encumbrance, attempted assignment or attempted encumbrance.  Without limiting the generality of the foregoing, if the L-C expires earlier than
the L‑C Expiration Date, Landlord will

accept  a  renewal  thereof  (such  renewal  letter  of  credit  to  be  in  effect  and  delivered  to  Landlord,  as  applicable,  not  later  than  thirty  (30)  days  prior  to  the
expiration of the L-C), which shall be irrevocable and automatically renewable as above provided through the L‑C Expiration Date upon substantially the
same terms as the expiring L‑C or such  other terms as may be acceptable to Landlord in its reasonable discretion.  If Tenant exercises its option to extend the
Lease Term pursuant to Section 2.2 then, not later than thirty (30) days prior to the commencement of the Option Term, Tenant shall deliver to Landlord a
new L C or certificate of renewal or extension evidencing the L-C Expiration Date as thirty (30) days after the expiration of the Option Term.  However, if the
L‑C is not timely renewed, or if Tenant fails to maintain the L‑C in the amount and in accordance with the terms set forth in this Article 21, Landlord shall
have the right to present the L‑C to the Bank in accordance with the terms of this Article 21, and the proceeds of the L-C shall be applied by Landlord against
any Rent payable by Tenant under this Lease that is not paid when due and/or to pay for all losses and damages that Landlord has suffered or that Landlord
reasonably estimates that it will suffer as a result of any breach or default by Tenant under this Lease.  In the event Landlord elects to exercise its rights as
provided  above,  (I)  any  unused  proceeds  shall  constitute  the  property  of  Landlord  (and  not  Tenant’s  property  or,  in  the  event  of  a  receivership,
conservatorship, or a bankruptcy filing by, or on behalf of, Tenant, property of such receivership, conservatorship or Tenant’s bankruptcy estate) and need not
be segregated from Landlord’s other assets, and (II) Landlord agrees to pay to Tenant within thirty (30) days after the L‑C Expiration Date the amount of any
proceeds of the L-C received by Landlord and not applied against any Rent payable by Tenant under this Lease that was not paid when due or used to pay for
any losses and/or damages suffered by Landlord (or reasonably estimated by Landlord that it will suffer) as a result of any breach or default by Tenant under
this Lease; provided, however, that if prior to the L‑C Expiration Date a voluntary petition is filed by Tenant, or an involuntary petition is filed against Tenant
by  any  of  Tenant’s  creditors,  under  the  Bankruptcy  Code,  then  Landlord  shall  not  be  obligated  to  make  such  payment  in  the  amount  of  the  unused  L-C
proceeds  until  either  all  preference  issues  relating  to  payments  under  this  Lease  have  been  resolved  in  such  bankruptcy  or  reorganization  case  or  such
bankruptcy or reorganization case has been dismissed.  If Landlord draws on the L-C due to Tenant’s failure to timely renew or provide a replacement L-C,
such failure shall not be considered a default under this Lease and Landlord shall return such cash proceeds upon Tenant’s presentation of a replacement L-C
that satisfies the requirements of this Lease, subject to reasonable satisfaction of any preference risk to Landlord.

21.4

Transfer and Encumbrance.  The L-C shall also provide that Landlord may, at any time and without notice to Tenant and without
first  obtaining  Tenant's  consent  thereto,  transfer  (one  or  more  times)  its  entire  interest  in  and  to  the  L-C  to  another  party,  person  or  entity,  provided  such
transfer is in connection with the assignment by Landlord of its rights and interests in and to this Lease.  In the event of a transfer of Landlord's interest in
under  this  Lease,  Landlord  shall  transfer  the  L-C  to  the  transferee  and  thereupon  Landlord  shall,  without  any  further  agreement  between  the  Parties,  be
released by Tenant from all liability therefor, and it is agreed that the provisions hereof shall apply to every transfer or assignment of the whole of said L-C to
a new landlord.  In connection with any such transfer of the L-C by Landlord, Tenant shall, at Tenant's sole cost and expense, execute and submit to the Bank
such applications, documents and instruments as may be necessary to effectuate such transfer and, Tenant shall be responsible for paying the Bank's transfer
and processing fees in connection therewith; provided that, Landlord shall have the right (in its sole discretion), but not the obligation, to pay such fees on
behalf of Tenant, in which case Tenant shall reimburse Landlord within ten (10) business days after Tenant's receipt of an invoice from Landlord therefor.

21.5

L-C Not a Security Deposit.  Landlord and Tenant (1) acknowledge and agree that in no event or circumstance shall the L‑C or any
renewal thereof or substitute therefor or any proceeds thereof be deemed to be or treated as a “security deposit” under any law applicable to security deposits
in the commercial context, including Section 1950.7 of the California Civil Code, as such Section now exists or as it may be hereafter amended or succeeded
(the “Security Deposit Laws”), (2) acknowledge and agree that the L‑C (including any renewal thereof or substitute therefor or any proceeds thereof) is not
intended to serve as a security deposit, and the Security Deposit Laws shall have no applicability or relevancy thereto, and (3) waive any and all rights, duties
and obligations that any such Party may now, or in the future will, have relating to or arising from the Security Deposit Laws.  Tenant  hereby  irrevocably
waives  and  relinquishes  the  provisions  of  Section  1950.7  of  the  California  Civil  Code  and  any  successor  statute,  and  all  other  provisions  of  law,  now  or
hereafter in effect, that (x) establish the time frame by which a landlord must refund a security deposit under a lease, and/or (y) provide that a landlord may
claim from a security deposit only those sums reasonably necessary to remedy defaults in the payment of rent, to repair damage caused by a tenant or to clean
the  premises,  it  being  agreed  that  Landlord  may,  in  addition,  claim  those  sums  specified  in  this  Article 21  and/or  those  sums  reasonably  necessary  to  (a)
compensate Landlord for any loss or damage caused by Tenant's breach of this Lease, including any damages Landlord suffers following termination of this
Lease, and/or (b) compensate Landlord for any

and all damages arising out of, or incurred in connection with, the termination of this Lease, including those specifically identified in Section 1951.2 of the
California Civil Code.  Tenant agrees not to interfere in any way with any payment to Landlord of the proceeds of the L-C, either prior to or following a
"draw" by Landlord of all or any portion of the L-C, regardless of whether any dispute exists between Tenant and Landlord as to Landlord's right to draw
down  all  or  any  portion  of  the  L-C.    No  condition  or  term  of  this  Lease  shall  be  deemed  to  render  the  L‑C  conditional  and  thereby  afford  the  Bank  a
justification for failing to honor a drawing upon such L-C in a timely manner.  Tenant shall not request or instruct the Bank of any L‑C to refrain from paying
sight draft(s) drawn under such L‑C.

21.6

Remedy for Improper Drafts.  Tenant's sole remedy in connection with the improper presentment or payment of sight drafts drawn
under any L‑C shall be the right to obtain from Landlord a refund of the amount of any sight draft(s) that were improperly presented or the proceeds of which
were misapplied, and reasonable actual out-of-pocket attorneys' fees, provided that at the time of such refund, Tenant increases the amount of such L‑C to the
amount (if any) then required under the applicable provisions of this Lease.  Tenant acknowledges that the presentment of sight drafts drawn under any L‑C,
or the Bank's payment of sight drafts drawn under such L‑C, could not under any circumstances cause Tenant injury that could not be remedied by an award
of  money  damages,  and  that  the  recovery  of  money  damages  would  be  an  adequate  remedy  therefor.    In  the  event  Tenant  shall  be  entitled  to  a  refund  as
aforesaid and Landlord shall fail to make such payment within ten (10) business days after demand, Tenant shall have the right to deduct the amount thereof
from the next installment(s) of Base Rent.

COMMUNICATIONS  AND  COMPUTER  LINE

22.
Tenant  may  install,  maintain,  replace,  remove  or  use  any  communications  or
computer wires and cables serving the Premises (collectively, the "Lines"), provided that Tenant shall use an experienced and qualified contractor approved in
writing by Landlord, and comply with all of the other provisions of Articles 7 and 8.  Tenant shall pay all costs in connection therewith.  Tenant shall not be
obligated to remove any Lines located in or serving the Premises upon the expiration or earlier termination of this Lease.

23.

SIGNS

23.1

Exterior Signage.  Subject to Landlord's prior written approval, which shall not be unreasonably withheld, conditioned or delayed,
and  provided  all  signs  are  in  keeping  with  the  quality,  design  and  style  of  the  Building  and  Project,  Tenant,  at  its  sole  cost  and  expense,  may  install
identification  signage  at  the  exterior  entrance  to  the  Building,  as  well  as  internal  directional,  suite  entry  and  lobby  identification  signage  and  directory
(collectively,  "Tenant  Signage");  provided,  however,  in  no  event  shall  Tenant's  Signage  include  an  "Objectionable  Name,"  as  that  term  is  defined  in
Section  23.3,  of  this  Lease.    All  such  signage  shall  be  subject  to  Tenant's  obtaining  all  required  governmental  approvals.    All  permitted  signs  shall  be
maintained by Tenant at its expense in a first-class and safe condition and appearance.  Upon the expiration or earlier termination of this Lease, Tenant shall
remove all of its signs at Tenant's sole cost and expense.  The graphics, materials, color, design, lettering, lighting, size, illumination, specifications and exact
location of Tenant's Signage (collectively, the "Sign Specifications") shall be subject to the prior written approval of Landlord, which approval shall not be
unreasonably  withheld,  conditioned  or  delayed,  and  shall  be  consistent  and  compatible  with  the  quality  and  nature  of  the  Project.    Tenant  hereby
acknowledges that, notwithstanding Landlord's approval of Tenant's Signage, Landlord has made no representation or warranty to Tenant with respect to the
probability  of  obtaining  all  necessary  governmental  approvals  and  permits  for  Tenant's  Signage.    In  the  event  Tenant  does  not  receive  the  necessary
governmental approvals and permits for Tenant's Signage, Tenant's and Landlord's rights and obligations under the remaining terms of this Lease shall be
unaffected.  If Landlord elects to install a multi-tenant identification sign at the entrance to the Project, Tenant shall be entitled to install its name on such sign
(subject to availability on a pro-rata basis based on the relative square footages leased by the tenants of the Project), at Tenant's sole cost and expense.

23.2

Objectionable Name.  Tenant's Signage shall not include a name or logo that relates to an entity that is of a character or reputation,
or is associated with a political faction or orientation, that is inconsistent with the quality of the Project, or that would otherwise reasonably offend a landlord
of the Comparable Buildings (an "Objectionable Name").  The parties hereby agree that the following name, or any reasonable derivation thereof, shall be
deemed not to constitute an Objectionable Name:  "Allogene Therapeutics, Inc.."

23.3

Prohibited Signage and Other Items.  Any signs, notices, logos, pictures, names or advertisements that are installed and that have
not  been  separately  approved  by  Landlord  may  be  removed  without  notice  by  Landlord  at  the  sole  expense  of  Tenant.    Landlord  may  in  its  reasonable
discretion require the removal of any signs, window coverings, or blinds (even if the same are located behind the Landlord-approved window coverings for
the Building), or other items reasonably visible from the exterior of the Premises or Building.

COMPLIANCE WITH LAW

24.
Tenant shall not do anything or suffer anything to be done in or about the Premises or the Project that will
in any way conflict with any law, statute, ordinance or other governmental rule, regulation or requirement now in force or that may hereafter be enacted or
promulgated.    At  its  sole  cost  and  expense,  Tenant  shall  promptly  comply  with  all  such  governmental  measures  pertaining  to  Tenant’s  use  of  the
Premises.  Should any standard or regulation now or hereafter be imposed on Landlord or Tenant by a state, federal or local governmental body charged with
the establishment, regulation and enforcement of occupational, health or safety standards for employers, employees, landlords or tenants, then Tenant agrees,
at its sole cost and expense, to comply promptly with such standards or regulations.  Tenant shall be responsible, at its sole cost and expense, to make all
alterations  to  the  Building  and  Premises  as  are  required  to  comply  with  the  governmental  rules,  regulations,  requirements  or  standards  described  in  this
Article 24 pertaining to Tenant’s use of the Premises.  The judgment of any court of competent jurisdiction or the admission of Tenant in any judicial action,
regardless of whether Landlord is a party thereto, that Tenant has violated any of said governmental measures, shall be conclusive of that fact as between
Landlord and Tenant.  Tenant's obligations under this Article 24 are subject to the limitation in Section 10.2.  For purposes of Section 1938 of the California
Civil Code, Landlord hereby discloses to Tenant, and Tenant hereby acknowledges, that the Project, Building and Premises have not undergone inspection by
a Certified Access Specialist (CASp).  As required by Section 1938(e) of the California Civil Code, Landlord hereby states as follows:  "A Certified Access
Specialist  (CASp)  can  inspect  the  subject  premises  and  determine  whether  the  subject  premises  comply  with  all  of  the  applicable  construction-related
accessibility standards under state law.  Although state law does not require a CASp inspection of the subject premises, the commercial property owner or
lessor may not prohibit the lessee or tenant from obtaining a CASp inspection of the subject premises for the occupancy or potential occupancy of the lessee
or tenant, if requested by the lessee or tenant.  The parties shall mutually agree on the arrangements for the time and manner of the CASp inspection, the
payment of the fee for the CASp inspection, and the cost of making any repairs necessary to correct violations of construction-related accessibility standards
within the premises."  In furtherance of the foregoing, Landlord and Tenant hereby agree as follows:  (a) any CASp inspection requested by Tenant shall be
conducted, at Tenant's sole cost and expense, by a CASp approved in advance by Landlord; and (b) Tenant shall be responsible, at Tenant's sole cost and
expense, to make any modifications to the Premises that it deems to be required as a result of any such CASp inspection.

LATE CHARGES

25.
If any installment of Rent or any other sum due from Tenant shall not be received by Landlord or Landlord's designee
within five (5) business days after Tenant's receipt of written notice from Landlord that said amount is delinquent, then Tenant shall pay to Landlord a late
charge equal to five percent (5%) of the overdue amount plus any reasonable attorneys' fees incurred by Landlord by reason of Tenant's failure to pay Rent
and/or other charges when due hereunder.  The late charge shall be deemed Additional Rent and the right to require it shall be in addition to all of Landlord's
other rights and remedies hereunder or at law and shall not be construed as liquidated damages or as limiting Landlord's remedies in any manner.  In addition
to the late charge described above, any Rent or other amounts owing hereunder that are not paid within ten (10) business days after Tenant's receipt of written
notice that said amount is delinquent shall bear interest from the date when due until paid at a rate per annum equal to the lesser of (i) the annual "Bank Prime
Loan"  rate  cited  in  the  Federal  Reserve  Statistical  Release  Publication  G.13(415),  published  on  the  first  Tuesday  of  each  calendar  month  (or  such  other
comparable index as Landlord and Tenant shall reasonably agree upon if such rate ceases to be published) plus four (4) percentage points, and (ii) the highest
rate permitted by applicable law.

26.

LANDLORD'S RIGHT TO CURE DEFAULT; PAYMENTS BY TENANT

26.1

Landlord's Cure.  All covenants and agreements to be kept or performed by Tenant under this Lease shall be performed by Tenant
at Tenant's sole cost and expense and without any reduction of Rent, except to the extent, if any, otherwise expressly provided herein.  If Tenant shall fail to
perform any obligation under this Lease, and such failure shall continue in excess of the time allowed under Section 19.1.2, unless a specific time period is
otherwise stated in this Lease, Landlord may, but shall not be obligated to, make any such payment or perform any such act on Tenant's part without waiving
its rights based upon any default of Tenant and without releasing Tenant from any obligations hereunder.

26.2

Tenant's Reimbursement.  Except as may be specifically provided to the contrary in this Lease, Tenant shall pay to Landlord, upon
delivery by Landlord to Tenant of statements therefor:  (i) sums equal to expenditures reasonably made and obligations incurred by Landlord in connection
with the remedying by Landlord of Tenant's defaults pursuant to the provisions of Section 26.1; (ii) sums equal to all losses, costs, liabilities, damages and
expenses referred to in Article 10; and (iii) subject to Section 29.21, sums equal to all expenditures made and obligations incurred by Landlord in collecting or
attempting to collect the Rent or in enforcing or attempting to enforce any rights of Landlord under this Lease or pursuant to law, including all reasonable
legal fees and other amounts so expended.  Tenant's obligations under this Section 26.2 shall survive the expiration or sooner termination of the Lease Term.

ENTRY  BY  LANDLORD

27.
Landlord  reserves  the  right  upon  twenty  four  (24)  hours’  prior  notice  to  Tenant  (except  in  the  case  of  an
emergency) to enter the Premises at all reasonable times to (i) inspect them; (ii) show the Premises to prospective purchasers, or to current or prospective
mortgagees, ground or underlying lessors or insurers or, during the last nine (9) months of the Lease Term, to prospective tenants; (iii) post notices of non-
responsibility (to the extent applicable pursuant to then applicable law); or (iv) repair the Premises or the Building, or for structural repairs to the Building or
the Building's systems and equipment as provided under this Lease. Landlord may make any such entries without the abatement of Rent, except as otherwise
provided in this Lease, and may take such reasonable steps as required to accomplish the stated purposes.  In an Emergency, Landlord shall have the right to
use any means that Landlord may deem proper to open the doors in and to the Premises.  Any entry into the Premises by Landlord in the manner hereinbefore
described shall not be deemed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an actual or constructive eviction of Tenant from any
portion of the Premises.  Landlord shall use commercially reasonable efforts to minimize any interference with Tenant's use of or access to the Premises in
connection  with  any  such  entry  and  shall  comply  with  Tenant’s  reasonable  security  measures.    Without  limiting  the  foregoing,  except  in  an  emergency,
Landlord shall not enter into any portion of the Premises identified to Landlord as an area containing sensitive business information unless accompanied by a
representative of Tenant.  Landlord shall hold confidential any information regarding Tenant’s business that it may learn as a result of any such entry.

TENANT PARKING

28.
Tenant shall have the right, without the payment of any parking charge or fee (other than as a reimbursement of
operating expenses to the extent allowed pursuant to the terms or Article 4), commencing on the Rent Commencement Date, to use the amount of parking set
forth in Section 9 of the Summary, in the on-site parking lot and garage that serves the Building.  Tenant shall abide by all reasonable rules and regulations
that are prescribed from time to time for the orderly operation and use of the parking facility where the parking passes are located (including any sticker or
other  identification  system  established  by  Landlord  and  the  prohibition  of  vehicle  repair  and  maintenance  activities  in  the  parking  facilities)  and  for  the
dedicated parking spaces, and shall cooperate in seeing that Tenant's employees and visitors also comply with such rules and regulations.  Tenant's use of the
Project parking facility and dedicated parking spaces shall be at Tenant's sole risk and Tenant acknowledges and agrees that Landlord shall have no liability
whatsoever  for  damage  to  the  vehicles  of  Tenant,  its  employees  and/or  visitors,  or  for  other  personal  injury  or  property  damage  or  theft  relating  to  or
connected with the parking rights granted herein or any of Tenant's, its employees' and/or visitors' use of the parking facilities.

29.

MISCELLANEOUS PROVISIONS

29.1

grammatical  changes  required  to  make  the  provisions  hereof  apply  either  to  corporations  or  partnerships  or  individuals,  men  or  women,  as  the  case  may
require, shall in all cases be assumed as though in each case fully expressed.  The captions of Articles and Sections are for convenience only and shall not be

29.2

Binding Effect.  Subject to all other provisions of this Lease, each of the covenants, conditions and provisions of this Lease shall
extend  to  and  shall,  as  the  case  may  require,  bind  or  inure  to  the  benefit  not  only  of  Landlord  and  of  Tenant,  but  also  of  their  respective  heirs,  personal
representatives, successors or assigns, provided this clause shall not permit any assignment by Tenant contrary to the provisions of Article 14 of this Lease.

29.3

No Air Rights.  No rights to any view or to light or air over any property, whether belonging to Landlord or any other person, are
granted to Tenant by this Lease.  If at any time any windows of the Premises are temporarily darkened or the light or view therefrom is obstructed by reason
of any repairs, improvements, maintenance or cleaning in or about the  Project, the same shall be without liability to Landlord and without any reduction or
diminution of Tenant's obligations under this Lease.

29.4

Modification  of  Lease.    Should  any  current  or  prospective  mortgagee  or  ground  lessor  for  the  Building  or  Project  require  a
modification of this Lease, which modification will not cause an increased cost or expense to Tenant or in any other way materially and adversely change the
rights and obligations of Tenant hereunder or interfere with Tenant's use of the Premises, then and in such event, Tenant agrees that this Lease may be so
modified  and  agrees  to  execute  whatever  documents  are  reasonably  required  therefor  and  to  deliver  the  same  to  Landlord  within  ten  (10)  business  days
following a request therefor.  At the request of Landlord or any mortgagee or ground lessor, Tenant agrees to execute a short form of Lease and deliver the
same to Landlord within ten (10) business days following the request therefor.

29.5

Transfer of Landlord's Interest.  Tenant acknowledges that Landlord has the right to transfer all or any portion of its interest in the
Project or Building and in this Lease, and Tenant agrees that in the event of any such transfer, Landlord shall automatically be released from all liability under
this  Lease  and  Tenant  agrees  to  look  solely  to  such  transferee  for  the  performance  of  Landlord's  obligations  hereunder  accruing  after  the  date  of  transfer
provided such transferee shall have fully assumed and agreed in writing to be liable for all obligations of this Lease to be performed by Landlord, including
the return of any security deposit, and Tenant shall attorn to such transferee.

29.6

Prohibition  Against  Recording.    Except  as  provided  in  Section  29.4  of  this  Lease,  neither  this  Lease,  nor  any  memorandum,

affidavit or other writing with respect thereto, shall be recorded by Tenant or by anyone acting through, under or on behalf of Tenant.

29.7

Landlord's Title.  Landlord's title is and always shall be paramount to the title of Tenant.  Nothing herein contained shall empower

Tenant to do any act which can, shall or may encumber the title of Landlord.

29.8

Relationship of Parties.  Nothing contained in this Lease shall be deemed or construed by the parties hereto or by any third party to

create the relationship of principal and agent, partnership, joint venturer or any association between Landlord and Tenant.

29.9

Payment under Protest.  If Tenant in good faith disputes any amounts billed by Landlord, other than (i) Base Rent, (ii) Tenant's
Share of Direct Expenses (as to which Tenant may exercise its rights under Section 4.6, above), Tenant may make payment of such amounts under protest,
and reserve all of its rights with respect to such amounts (the "Disputed Amounts").  Landlord and Tenant shall meet and confer to discuss the Disputed
Amounts and attempt, in good faith, to resolve the particular dispute.  If, despite such good faith efforts, Landlord and Tenant are unable to reach agreement
regarding the Disputed Amounts, either party may submit the matter to binding arbitration under the JAMS Streamlined Arbitration Rules & Procedures.  The
non-prevailing party, as determined by JAMS, will be responsible to pay all fees and costs incurred in connection with the JAMS procedure, as well as all
other  costs  and  expenses,  including  reasonable  attorneys'  fees,  incurred  by  the  prevailing  party.    This  Section  29.9  shall  not  apply  to  claims  relating  to
Landlord's exercise of any unlawful detainer rights pursuant to California law or rights or remedies used by Landlord to gain possession of the Premises or
terminate Lessee's right of possession to the Premises.

Time  of  Essence.    Time  is  of  the  essence  with  respect  to  the  performance  of  every  provision  of  this  Lease  in  which  time  of

performance is a factor.

29.11

Partial Invalidity.  If any term, provision or condition contained in this Lease shall, to any extent, be invalid or unenforceable, the
remainder of this Lease, or the application of such term, provision or condition to persons or circumstances other than those with respect to which it is invalid
or unenforceable, shall not be affected thereby, and each and every other term, provision and condition of this Lease shall be valid and enforceable to the
fullest extent possible permitted by law.

29.12

No Warranty.  In executing and delivering this Lease, Tenant has not relied on any representations, including, but not limited to,
any  representation  as  to  the  amount  of  any  item  comprising  Additional  Rent  or  the  amount  of  the  Additional  Rent  in  the  aggregate  or  that  Landlord  is
furnishing the same services to other tenants, at all, on the same level or on the same basis, or any warranty or any statement of Landlord which is not set
forth herein or in one or more of the exhibits attached hereto.

29.13

Landlord Exculpation.  The liability of Landlord or the Landlord Parties to Tenant for any default by Landlord under this Lease
or arising in connection herewith or with Landlord's operation, management, leasing, repair, renovation, alteration or any other matter relating to the Project
or  the  Premises  shall  be  limited  solely  and  exclusively  to  the  interest  of  Landlord  in  the  Project,  including  any  rental,  condemnation,  sales  and  insurance
proceeds received by Landlord or the Landlord Parties in connection with the Project, Building or Premises.  No Landlord Parties (other than Landlord) shall
have any personal liability therefor, and Tenant hereby expressly waives and releases such liability on behalf of itself and all persons claiming by, through or
under Tenant.  The limitations of liability contained in this Section 29.13 shall inure to the benefit of Landlord's and the Landlord Parties' present and future
partners, beneficiaries, officers, directors, trustees, shareholders, agents and employees, and their respective partners, heirs, successors and assigns.  Under no
circumstances shall any present or future partner of Landlord (if Landlord is a partnership), or trustee or beneficiary (if Landlord or any partner of Landlord is
a trust), have any liability for the performance of Landlord's obligations under this Lease.  Notwithstanding any contrary provision herein, neither Landlord
nor the Landlord Parties shall be liable under any circumstances for injury or damage to, or interference with, Tenant's business, including loss of profits, loss
of  rents  or  other  revenues,  loss  of  business  opportunity,  loss  of  goodwill  or  loss  of  use,  in  each  case,  however  occurring,  or  loss  to  inventory,  scientific
research, scientific experiments, laboratory animals, products, specimens, samples, and/or scientific, business, accounting and other records of every kind and
description kept at the premises and any and all income derived or derivable therefrom.

29.14

Entire Agreement.  It is understood and acknowledged that there are no oral agreements between the Parties affecting this Lease
and  this  Lease  constitutes  the  Parties'  entire  agreement  with  respect  to  the  leasing  of  the  Premises  and  supersedes  and  cancels  any  and  all  previous
negotiations,  arrangements,  brochures,  agreements  and  understandings,  if  any,  between  the  Parties  or  displayed  by  Landlord  to  Tenant  with  respect  to  the
subject matter thereof, and none thereof shall be used to interpret or construe this Lease.  None of the terms, covenants, conditions or provisions of this Lease
can be modified, deleted or added to except in writing signed by the Parties.

29.15

Right to Lease.  Landlord reserves the absolute right to effect such other tenancies in the Project as Landlord in the exercise of its
sole business judgment shall determine to best promote the interests of the Building or Project.  Tenant does not rely on the fact, nor does Landlord represent,
that any specific tenant or type or number of tenants shall, during the Lease Term, occupy any space in the Project.

29.16

Force Majeure.  Any prevention, delay or stoppage due to strikes, lockouts, labor disputes, acts of God, acts of war, terrorist acts,
inability  to  obtain  services,  labor,  or  materials  or  reasonable  substitutes  therefor,  governmental  actions,  civil  commotions,  fire  or  other  casualty,  and  other
causes beyond the reasonable control of the Party obligated to perform, except with respect to the obligations imposed with regard to Rent and other charges
to be paid by Tenant pursuant to this Lease (collectively, a "Force Majeure"), notwithstanding anything to the contrary contained in this Lease, shall excuse
the  performance  of  such  Party  for  a  period  equal  to  any  such  prevention,  delay  or  stoppage  and,  therefore,  if  this  Lease  specifies  a  time  period  for
performance of an obligation of either Party, that time period shall be extended by the period of any delay in such Party's performance caused by a Force
Majeure, provided, however, the foregoing delays shall not apply to Tenant's termination rights hereunder.

connection with the negotiation of this Lease, excepting only the real estate brokers or agents specified in Section 12 of the Summary (the "Brokers"), and

termination of the Lease Term.

29.25

Independent  Covenants.    This  Lease  shall  be  construed  as  though  the  covenants  herein  between  Landlord  and  Tenant  are
independent and not dependent and Tenant hereby expressly waives the benefit of any statute to the contrary and agrees that if Landlord fails to perform its

Section 23.1, to install, affix and maintain any and all signs on the exterior and on the interior of the Project as Landlord may, in Landlord's sole discretion,
desire.  Tenant shall not use the name of the Project or Building or use pictures or illustrations of the Project or Building in advertising or other publicity or

Development of the Project.  

29.29.1

Subdivision.  Landlord reserves the right to subdivide all or a portion of the buildings and Common Areas, so long
as the same does not interfere with Tenant's use of or access to the Premises or Tenant's parking rights.  Tenant agrees to execute and deliver, upon demand by
Landlord and in the form requested by Landlord, any additional documents needed to conform this Lease to the circumstances resulting from a subdivision
and  any  all  maps  in  connection  therewith,  so  long  as  the  same  does  not  increase  Tenant's  obligations  or  decrease  Tenant's  rights  under  this
Lease.  Notwithstanding anything to the contrary set forth in this Lease, the separate ownership of any buildings and/or Common Areas by an entity other
than Landlord shall not affect the calculation of Direct Expenses or Tenant's payment of Tenant's Share of Direct Expenses.

Construction  of  Property  and  Other  Improvements.    Tenant  acknowledges  that  portions  of  the  Project  may  be
under construction following Tenant's occupancy of the Premises, and that such construction may result in levels of noise, dust, obstruction of access, etc. that
are  in  excess  of  that  present  in  a  fully  constructed  project.    Landlord  shall  use  commercially  reasonable  efforts  to  minimize  the  impact  of  such
construction.  Tenant hereby waives any and all rent offsets or claims of constructive eviction that may arise in connection with such construction, so long as
the same does not interfere with Tenant's use of or access to the Premises or Tenant's parking rights.

29.30

No Violation.  Tenant hereby warrants and represents that neither its execution of nor performance under this Lease shall cause
Tenant to be in violation of any agreement, instrument, contract, law, rule or regulation by which Tenant is bound, and Tenant shall protect, defend, indemnify
and  hold  Landlord  harmless  against  any  claims,  demands,  losses,  damages,  liabilities,  costs  and  expenses,  including  reasonable  attorneys'  fees  and  costs,
arising from Tenant's breach of this warranty and representation.

transportation or traffic in and around the Project and/or the Building, and in connection therewith, Tenant shall take responsible action for the transportation
planning  and  management  of  all  employees  located  at  the  Premises  by  working  directly  with  Landlord,  any  governmental  transportation  management
organization or any other transportation-related committees or entities.  Such programs may include, without limitation: (i) restrictions on the number of peak-
hour  vehicle  trips  generated  by  Tenant;  (ii)  increased  vehicle  occupancy;  (iii)  implementation  of  an  in-house  ridesharing  program  and  an  employee
transportation  coordinator;  (iv)  working  with  employees  and  any  Project,  Building  or  area-wide  ridesharing  program  manager;  (v)  instituting  employer-
sponsored incentives (financial or in-kind) to encourage employees to rideshare; and (vi) utilizing flexible work shifts for employees.

TENANT WORK LETTER

This Tenant Work Letter shall set forth the terms and conditions relating to the initial improvement of the Premises for Tenant following the date
of this Lease.  This Tenant Work Letter is essentially organized chronologically and addresses the issues of construction, in sequence, as such issues will arise
during construction in the Premises.    

Tenant acknowledges that Tenant shall accept the Premises in their existing, "as-is" condition on the date of delivery thereof to Tenant, subject to
Section 1.1.1 of the Lease.  Except for the payment of the Tenant Improvement Allowance as provided in Section 2, below, Landlord shall have no obligation
to make or pay for any improvements to the Premises.

SECTION 1

SECTION 2

2.1

Tenant Improvement Allowance.   Commencing as of the Execution Date, Tenant shall be entitled to use the "Tenant Improvement
Allowance", as defined in Section 5 of the Summary to this Lease, for the costs relating to the initial design and construction of Tenant's improvements, which
are permanently affixed to the Premises or which are "Tenant Improvement Allowance Items," as that term is defined in Section 2.2.1, below (collectively, the
"Tenant Improvements").  In no event shall Landlord be obligated to make disbursements pursuant to this Tenant Work Letter or otherwise in connection
with Tenant's construction of the Tenant Improvements or any Tenant Improvement Allowance Items, as defined below, in a total amount which exceeds the

approval of the "Final Working Drawings", as that term is defined in Section 3.3, below, require Tenant, prior to the end of the Lease Term, or given following
any earlier termination of this Lease, at Tenant's expense, to remove any Tenant Improvements and to repair any damage to the Premises and Building caused
by such removal and return the affected portion of the Premises to a Building standard general office condition, provided, however, that Landlord may not
require  Tenant  to  remove  any  Alterations  which  are  otherwise  consistent  with  typical  tenant  improvements  in  the  biotechnology  or  pharmaceutical
industries.    Landlord  hereby  acknowledges  and  agrees  that  the  following  do  not  need  to  be  removed  if  installed:  clean  suites,  and  any  office  space.    Any
portion of the Tenant Improvement Allowance that is not disbursed or allocated for disbursement by December 31, 2020, shall revert to Landlord and Tenant
shall have no further rights with respect thereto.

reasonably requested by Landlord.  As between Landlord and Tenant only, Tenant's request for payment shall be deemed Tenant's acceptance and approval of

such amounts shall not be deemed Landlord's approval or acceptance of the work furnished or materials supplied as set forth in Tenant's payment request.

Final Deliveries.    Following  the  completion  of  construction  of  the  Tenant  Improvements,  Tenant  shall
deliver to Landlord properly executed final mechanic's lien releases in compliance with both California Civil Code Section 8134 and either Section 8136 or

completed.  Tenant shall record a valid Notice of Completion in accordance with the requirements of Section 4.3 of this Tenant Work Letter.

2.2.2.2

Other Terms.    Landlord  shall  only  be  obligated  to  make  disbursements  from  the  Tenant  Improvement

written notice to Landlord given on or before December 31, 2020, to use up to $25.00 per rentable square foot of the Premises (i.e., up to $373,575.00) (the
"Additional TI Allowance") towards the payment of the costs of the Tenant Improvement Allowance Items.  In the event Tenant exercises its right to use all
or  any  portion  of  the  Additional  TI  Allowance,  Tenant  shall  be  required  to  pay  Landlord,  commencing  on  Rent  Commencement  Date  (the  "Additional
Payment  Commencement  Date"),  the  "Additional  TI  Allowance  Payment,"  as  that  term  is  defined  below,  in  consideration  of  Landlord  provision  of  the

(i) the amount of the Additional TI Allowance utilized by Tenant as the present value amount, (ii) a number equal to the number of full calendar months then
remaining in the Lease Term as the number of payments, (iii) a monthly interest factor equal to seventy-five one-hundredths percent (0.75%), which is equal
to  nine  percent  (9%)  divided  by  twelve  (12)  months  per  year,  and  (iv)  the  Additional  TI  Allowance  Payment  as  the  missing  component  of  the
annuity.  Following the calculation of the Additional TI Allowance Payment, Landlord and Tenant will enter into a lease amendment to confirm the amount
thereof.    Any  portion  of  the  Tenant  Improvement  Allowance  that  is  not  disbursed  or  allocated  for  disbursement  by  December  31,  2020,  shall  revert  to
Landlord and Tenant shall have no further rights with respect thereto.  

SECTION 3

3.1

Selection of Architect.   Tenant  shall  retain  an  architect/space  planner  (the  "Architect")  approved  in  advance  by  Landlord  (which

Clemente Hale Studios is hereby approved as Architect if selected by Tenant.  Tenant shall retain the engineering consultants or design/build subcontractors
designated by Tenant and reasonably approved in advance by Landlord (the "Engineers") to prepare all plans and engineering working drawings relating to
the structural, mechanical, electrical, plumbing, HVAC, lifesafety, and sprinkler work in the Premises, which work is not part of the Base Building.  CRB is
hereby approved as Tenant’s laboratory process engineer and laboratory consultant.  All such plans and drawings shall comply with the reasonable industry

and Landlord shall have no responsibility in connection therewith.  Landlord's review of any plans or drawings as set forth in this Section 3, shall be for its
sole purpose and shall not imply Landlord's review of the same, or obligate Landlord to review the same, for quality, design, Code compliance or other like
matters.

3.2

Final Space Plan.  Tenant shall supply Landlord with four (4) copies signed by Tenant of its final space plan for the Premises before
any architectural working drawings or engineering drawings have been commenced.  The final space plan (the "Final Space Plan") shall include a layout and
designation of all offices, labs, rooms and other partitioning, their intended use, and equipment to be contained therein.  Landlord may request clarification or
more specific drawings for special use items not included in the Final Space Plan.  Landlord shall advise Tenant within five (5) business days after Landlord's
receipt of the Final Space Plan for the Premises if the same is unsatisfactory or incomplete in any respect.  If Tenant is so advised, Tenant shall promptly
cause the Final Space Plan to be revised to correct any deficiencies or other matters Landlord may reasonably require.  If Landlord fails to respond to the
Final Space Plan within the five (5) business day period set forth above, Tenant may send Landlord a notice setting forth such failure and warning that a
continuing failure to respond may result in a "deemed approval" (the "Final Space Plan Reminder Notice"). If Landlord fails to respond to the Final Space
Plan within two (2) business days after receipt of the Final Space Plan Reminder Notice, such portion of the Final Space Plan shall be deemed approved by
Landlord.  

3.3

Final  Working  Drawings.   After  the  Final  Space  Plan  has  been  approved  by  Landlord,  Tenant  shall  supply  the  Engineers  with  a
complete listing of standard and non-standard equipment and specifications, including, without limitation, Title 24 calculations, electrical requirements and
special electrical receptacle requirements for the Premises, to enable the Engineers and the Architect to complete the "Final Working Drawings" (as that term
is defined below) in the manner as set forth below.  Upon the approval of the Final Space Plan by Landlord and Tenant, Tenant shall promptly cause the
Architect and the Engineers to complete the architectural and engineering drawings for the Premises, and Architect shall compile a fully coordinated set of
architectural, structural, mechanical, electrical and plumbing working drawings in a form which is sufficiently complete to allow all of Tenant's Agents to bid
on  the  work  and  to  obtain  all  applicable  permits  (collectively,  the  "Final  Working  Drawings")  and  shall  submit  the  same  to  Landlord  for  Landlord's
approval, which shall not be unreasonably withheld, conditioned, or delayed.  Tenant shall supply Landlord with four (4) copies signed by Tenant of such
Final Working Drawings.  Landlord shall advise Tenant within ten (10) business days after Landlord's receipt of the Final Working Drawings for the Premises
if the same is unsatisfactory or incomplete in any respect.  If Tenant is so advised, Tenant shall promptly cause the Final Working Drawings to be revised in
accordance with such review and any disapproval of Landlord in connection therewith.  If Landlord fails to respond to the Final Construction Documents
within the ten (10) business day period set forth above, Tenant may send Landlord a notice setting forth such failure and warning that a continuing failure to
respond may result in a "deemed approval" (the "Final Construction Documents Reminder Notice").  If Landlord fails to respond to the Final Construction
Documents  within  five  (5)  business  days  after  receipt  of  the  Final  Construction  Documents  Reminder  Notice,  such  portion  of  the  Final  Construction
Documents shall be deemed approved by Landlord.

3.5

Approved Working Drawings.  The Final Working Drawings shall be approved by Landlord (the "Approved Working Drawings")
prior to the commencement of construction of the Premises by Tenant.  Concurrently with Tenant's delivery of the Final Working Drawings to Landlord for
Landlord's approval, Tenant may submit the same to the appropriate municipal authorities for all applicable building permits, provided that Tenant shall have
the right to submit to the City a  coordinated set of drawings, complete to the extent required to commence the plan check, the first phase in the permitting
process  (the  "Permit  Set"),  prior  to  approval  of  the  Final  Construction  Documents  by  Landlord  (and  Tenant  acknowledges  that  Landlord  shall  not  be
responsible  for  any  delays  or  costs  incurred  by  Tenant  in  the  event  that  Landlord  requires  revisions  to  the  Final  Working  Drawings  after  the  date  of  such
submission  of  plans  to  the  City  by  Tenant).   Tenant  hereby  agrees  that  neither  Landlord  nor  Landlord's  consultants  shall  be  responsible  for  obtaining  any
building permit or certificate of occupancy for the Premises and that obtaining the same shall be Tenant's responsibility; provided, however, that Landlord
shall cooperate with Tenant in executing permit applications and performing other ministerial acts reasonably necessary to enable Tenant to obtain any such
permit  or  certificate  of  occupancy.    No  changes,  modifications  or  alterations  in  the  Approved  Working  Drawings  may  be  made  without  the  prior  written
consent of Landlord, which shall not be unreasonably withheld, conditioned, or delayed.

Completed  Operation  Coverage  insurance  required  by  Landlord,  which  is  to  be  maintained  for  ten  (10)  years  following  completion  of  the  work.    Such
insurance shall provide that it is primary insurance as respects the owner and that any other insurance maintained by owner is excess and noncontributing with
the insurance required hereunder.  The requirements for the foregoing insurance shall not derogate from the provisions for indemnification of Landlord by
Tenant under Section 4.2.2.2 of this Tenant Work Letter.

4.2.2

Governmental Compliance.  The Tenant Improvements shall comply in all respects with the following:  (i) all state,
federal,  city  or  quasi-governmental  laws,  codes,  ordinances  and  regulations,  as  each  may  apply  according  to  the  rulings  of  the  controlling  public  official,

however,  that  Landlord's  failure  to  inspect  the  Tenant  Improvements  shall  in  no  event  constitute  a  waiver  of  any  of  Landlord's  rights  hereunder  nor  shall
Landlord's inspection of the Tenant Improvements constitute Landlord's approval of the same.  Should Landlord reasonably disapprove any portion of the
Tenant Improvements, on the grounds that the construction is defective or fails to comply with the Approved Working Drawings, Landlord shall notify Tenant
in writing of such disapproval and shall specify the items disapproved.  Any such defects or deviations shall be rectified by Tenant at no expense to Landlord,
provided however, that in the event Landlord determines that a defect or deviation exists that might adversely affect the mechanical, electrical, plumbing,
heating, ventilating and air conditioning or life-safety systems of the Building, the structure or exterior appearance of the Building or any other tenant's use of
such other tenant's leased premises, Landlord may, take such action as Landlord reasonably deems necessary, at Tenant's expense and without incurring any
liability  on  Landlord's  part,  to  correct  any  such  defect,  deviation  and/or  matter,  including,  without  limitation,  causing  the  cessation  of  performance  of  the
construction of the Tenant Improvements until such time as the defect, deviation and/or matter is corrected to Landlord's reasonable satisfaction.

☐ Yes   ☐ No, not required.  ☐ No, but one will be prepared and submitted, and a copy will be provided to the landlord property
management company.

If one has been completed, please attach a copy.  Continue to provide updated versions as they are completed. This is a legal requirement in
that State law requires that the owner/operator of a business located on leased or rented real property shall notify, in writing, the owner of the
property that the business is subject to and is in compliance with the Hazardous Materials Business Plan requirements (Health and Safety
Code Chapter 6.95 Section 25505.1).

NOTE: Please be advised that if you are involved in any tenant improvements that require a construction permit, you will be asked to provide
the local city with a Hazardous Materials Inventory Statement (HMIS) to ensure that your hazardous chemicals fall within the applicable Fire
Code fire control area limits for the applicable construction occupancy of the particular building.  The HMIS will include much of the
information listed in Section 2-2.  Neither the landlord nor the landlord’s property management company expressly warrants that the
inventory provided in Section 2-2 will necessarily meet the applicable California Fire Code fire control area limits for building occupancy,
especially in shared tenant occupancy situations. It is the responsibility of the tenant to ensure that a facility and site can legally handle the
intended operations and hazardous materials desired/ needed for its operations, but the landlord is happy to assist in this determination when
possible.

"Premises").  

The  Building,  together  with  the  other  two  (2)  adjacent  buildings  (i.e.  Building  2  and  Building  3),  together  with  the  legal
parcels on which the buildings are situated, and the other improvements and common areas located on such legal parcel as
shown on Exhibit A-1 attached hereto (collectively, the "Project").

That  certain  building  containing  approximately  117,889  rentable  square  feet  of  space  (inclusive  of  approximately  4,325
rentable  square  feet  of  mezzanine  area)  to  be  constructed  within  the  Project  and  located  at  7400  Gateway  Boulevard,

Commencement Date:

Beginning  on  the  Commencement  Date  (as  defined  below)  and  ending  on  the  last  day  of  the  one  hundred  eighty-eighth

event of Force Majeure (as applicable) actually delays Tenant in completing the Tenant Improvements by the expiration of
the then applicable Buildout Period; provided, however, notwithstanding the foregoing, in no event shall Tenant be permitted
to claim more than thirty (30) days of delay (in the aggregate)  as a result of Force Majeure.

covenants, and conditions hereof, Landlord leases to Tenant, and Tenant leases from Landlord, the Premises, to have and to hold for the Lease Term, subject
to the terms, covenants and conditions of this Lease.  After the Commencement Date, each of Landlord and Tenant shall, within a reasonable period of time
(not to exceed 30 days) following the other party's written request therefor, execute and deliver to each other a Confirmation of the Commencement Date in a
form reasonably approved by Landlord and Tenant; provided, however, that failure by either party to execute such Confirmation of the Commencement Date
shall  not  affect  the  actual  Commencement  Date  under  this  Lease.   The  term  of  this  Lease  shall  commence  on  the  "Commencement  Date"  specified  in  or
established above, and except as otherwise provided herein, shall continue in full force and effect through the number of months as provided above in the
Basic Lease Provisions (the "Lease Term"); provided, however, that if the Commencement Date is a date other than the first day of a calendar month, then
the Lease Term shall consist of the Commencement Date and the remainder of the calendar month including and following the Commencement Date, plus
said number of full calendar months in the Lease Term.  Subject to compliance with Legal Requirements and Private Restrictions, Tenant shall have the right
to access the Premises twenty-four (24) hours per day, seven (7) days per week throughout the Lease Term.  

(b)

If Landlord cannot, for any reason, deliver the Premises to Tenant by the Estimated Delivery Date set forth in the Basic
Lease Provisions above, then this Lease shall not be deemed void or voidable nor shall Landlord be deemed to be in default hereunder, nor shall Landlord be
liable  for  any  loss  or  damage  directly  or  indirectly  arising  out  of  such  delay.    Subject  to  extension  for  any  delay  caused  by  Force  Majeure  (as  defined  in
Paragraph 33 below) and/or any Tenant Delays (as defined in Exhibit B attached hereto), if Substantial Completion of the Landlord Work fails to occur by the
date which is thirty (30) days following the Estimated Delivery Date  (as extended by Force Majeure and/or any Tenant Delays) (the "First Outside Date"),
then, as Tenant's sole and exclusive remedy, commencing on the day following the First Outside Date, Tenant shall receive a day-for-day credit of Base Rent
for each day following such Outside Date until the earlier of (i) the Commencement Date, or (ii) the Second Outside Date (as defined below), which credit
shall be applicable to Base Rent first otherwise coming due during the Lease Term after the application of the Base Rent Credit (as defined in Paragraph 4(b)
below), provided that Tenant shall remain liable for the payment of any other charges under this Lease, including, without limitation, Operating Expenses, as
otherwise required under this Lease during such period when Base Rent is abated pursuant hereto.  Tenant shall commence the regular payment of Base Rent
(at the then applicable rates), computed in the way and manner as provided by this Lease, upon the Commencement Date, subject to such credit right (and the
Base  Rent  Credit,  as  defined  in  Paragraph  4(b)  below)  in  the  event  that  Substantial  Completion  of  the  Landlord  Work  occurs  after  the  First  Outside
Date.  Notwithstanding any provision to the contrary contained herein, but subject to extension for any delay caused by Force Majeure and/or any Tenant
Delays, if Substantial Completion of the Landlord Work has not occurred by the date which is ninety (90) days following the First Outside Date (as extended
by Force Majeure and/or any Tenant Delay, the "Second Outside Date"), then Tenant shall thereafter, prior to the Substantial Completion of the Landlord
Work, have the right (as Tenant's sole and exclusive remedy) to terminate this Lease by delivery of written notice of such election to Landlord, which notice
must  be  given,  if  at  all,  within  thirty  (30)  days  following  the  Second  Outside  Date,  and  this  Lease  shall  terminate  thirty  (30)  days  after  receipt  of  such
termination notice by Landlord; provided, however, that if Substantial Completion of the Landlord Work occurs during the 30-day period following receipt of
Tenant's notice of termination, Tenant's termination notice shall automatically be deemed null and void. In the event Tenant does not terminate this Lease
pursuant to this Paragraph 1(b),  then  this  Lease  shall  continue  in  full  force  and  effect;  provided,  however,  that  no  further  credits  against  Base  Rent  shall
accrue hereunder from and after the Second Outside Date.  If this Lease is terminated pursuant to the terms of this paragraph, then Tenant shall remove any
and all Tenant Improvements, furniture, fixtures and equipment that were installed by Tenant (or on behalf of Tenant) prior to such termination (whether in
accordance with Paragraph 1(c) below or otherwise), and repair any damage caused by such removal, and this Lease and the rights and obligations of the
parties pursuant to this Lease shall cease and terminate following which neither party shall have any further rights or obligations arising out of this Lease or
the termination of this Lease, except those rights and obligations expressly surviving expiration or earlier termination of this Lease.  For avoidance of doubt,
(a) Tenant shall no longer receive any credit against Base Rent following the Second Outside Date, and (b) if Tenant elects to terminate this Lease pursuant to
this Paragraph, (I) Tenant shall not receive any compensation from Landlord whatsoever except for a refund of the Prepaid Rent (with

1111154v7

4

 
 
 
 
Tenant  agreeing  and  acknowledging  that  any  credits  accrued  by  Tenant  shall  only  be  applicable  if  the  Commencement  Date  actually  occurs),  and  (II)
Landlord may require Tenant to remove, in Landlord's sole and absolute discretion, any and all Tenant Improvements, furniture, fixtures and equipment that
were installed by Tenant (or on behalf of Tenant) prior to such termination (whether in accordance with Paragraph 1(c) below or otherwise), and repair any
damage caused by such removal, which obligations shall expressly survive the termination of the Lease.  The remedies of Tenant set forth in this Paragraph
1(b) shall be Tenant's sole and exclusive remedies for failure of Landlord to timely cause Substantial Completion of the Landlord Work.

(c)

Subject  to  all  Legal  Requirements  and  Private  Restrictions,  Tenant  may  enter  the  Premises  approximately  ninety  (90)
days  prior  to  Substantial  Completion  of  the  Landlord  Work  for  the  sole  purposes  of  constructing  the  Tenant  Improvements,  installing  Tenant's  furniture,
fixtures and equipment in accordance with the terms and conditions contained in Exhibit B attached hereto, and taking other preparatory measures; provided,
however, that Tenant shall not unreasonably interfere with the completion of any of the Landlord Work and/or any Punchlist Items (as defined in Exhibit B
attached hereto).  Landlord and Tenant shall reasonably cooperate (and shall cause their respective contractors, subcontractors and agents to cooperate) with
each other in good faith to reasonably accommodate the construction scheduling of each party and in order that the work being performed by each party may
be completed without material interference with the completion of the work being completed by the other party and without increase in cost to the other party;
provided, however, notwithstanding the foregoing or anything herein to the contrary, Tenant acknowledges and agrees that in the event there is any conflict
between the construction scheduling or activities for completion of Tenant's work and the Landlord Work, the completion of the Landlord Work shall take
priority over the completion any Tenant's work and Tenant shall not interfere with (and Tenant shall cause its contractors, subcontractor and agents to not
interfere with) the completion of the Landlord Work. In the interest of clarity, Tenant acknowledges and agrees that the date of Substantial Completion may be
deemed to have occurred prior to the actual date of Substantial Completion due to the occurrence of one or more Tenant Delays, which may result in Tenant
not having access to the Premises for the full duration of the Buildout Period. As a condition to Tenant's right to such early entry, Tenant shall be required to
comply with all of the provisions of this Lease including, without limitation, the insurance and indemnity provisions contained in this Lease and with the
provisions of this Lease governing the Tenant Improvements, but excluding only the obligation to pay Base Rent and Operating Expenses. Notwithstanding
the foregoing, in no event shall Tenant access or enter into the Premises until such time as Tenant has delivered to Landlord written evidence that Tenant has
fulfilled its obligation to provide insurance pursuant to the provisions of this Lease. Such early entry in and of itself will not advance the Commencement
Date.  Tenant shall have no obligation to pay any Base Rent, utilities, or Operating Expenses until the Commencement Date has occurred, whereupon, subject
to  the  Base  Rent  Credit,  Base  Rent,  utilities,  and  Operating  Expenses  shall  immediately  commence.  During  any  such  early  entry,  Landlord  shall  not  be
responsible  for  any  loss,  including  theft,  damage  or  destruction  to  any  work  or  material  installed  or  stored  by  Tenant  at  the  Premises  or  for  any  injury  to
Tenant or its agents, employees, contractors, subcontractors, representatives, consultants, subtenants, assigns, licensees or invitees (each, a "Tenant Party"
and collectively, the "Tenant Parties"). Landlord shall have the right to post appropriate notices of non-responsibility in connection with any early entry by
Tenant.

(d)

All  references  in  this  Lease  to  "square  feet"  or  "square  footage"  shall  refer  to  rentable  square  feet  as  measured  in
accordance with the American National Standard Method of Measuring Floor Area in Industrial Buildings: Standard Methods of Measurement (ANSI/BOMA
Z65.2-2012) using drip line methodology (Method B), modified, if necessary, to include any mezzanine areas in the references to "square feet" and/or "square
footage".  

2.

Acceptance of Premises.  Subject to Landlord's obligations expressly set forth in this Lease, including Exhibit B attached hereto (and
Landlord's Construction Warranty [as defined and described therein]), Tenant shall accept the Premises in its "as-is" condition as of the date of Substantial
Completion of the Landlord Work.  EXCEPT FOR LANDLORD'S EXPRESS WARRANTIES SET FORTH IN THIS LEASE, LANDLORD HAS MADE
NO  REPRESENTATION  OR  WARRANTY  AS  TO  THE  SUITABILITY  OF  THE  PREMISES  OR  PROJECT  FOR  THE  CONDUCT  OF  TENANT'S
BUSINESS,  AND  TENANT  WAIVES  ANY  IMPLIED  WARRANTY  THAT  THE  PREMISES  OR  PROJECT  ARE  SUITABLE  FOR  TENANT'S
INTENDED PURPOSES.

3.

Use; Compliance with Legal Requirements; Tenant Management Period.

(a)

Subject to Tenant's compliance with all zoning ordinances and Legal Requirements (as hereinafter defined) and Private
Restrictions, the Premises shall be used only for the Permitted Use.  Tenant hereby acknowledges and agrees that warehouse distribution use under the current
BTP  Business  Technology  Park  Zoning  Regulations  is  limited  to  no  more  than  thirty-three  percent  (33%)  of  the  square  footage  of  the  Premises.
Notwithstanding  the  foregoing,  Landlord  acknowledges  and  agrees  that  Tenant  may  seek  one  or  more  conditional  use  permits,  variances  or  other
authorizations  from  the  applicable  Governmental  Authorities  to  increase  the  amount  of  square  footage  of  the  Premises  that  can  be  used  for  warehouse
distribution, or, subject to receipt of Landlord's prior written approval, to allow for different and/or additional uses than those currently permitted under the
BTP  Business  Technology  Park  Zoning  Regulations  in  the  Premises.  Without  limiting  the  foregoing,  Landlord  may  object  to  (and  prohibit  Tenant  from
proceeding with obtaining) any proposed conditional use permit, variance or other authorization if the same would materially and unreasonably impact any
other premises in the Project and/or the use, occupancy or enjoyment of any other occupant or potential occupant of other premises in the Project, or the same
would violate any Private Restrictions. Tenant shall not conduct or give notice of any auction, liquidation, or going out of business sale on the Premises or
Project.   Tenant  will  use  the  Premises  in  a  careful,  safe  and  proper  manner  and  will  not  commit  waste,  overload  the  floor  or  structure  of  the  Premises  or
subject the Premises to use that would damage the Premises.  Tenant shall not permit any unreasonably objectionable or unpleasant odors, smoke, dust, gas,
noise, or vibrations to emanate from the Premises, or take any other action that would constitute a nuisance or would unreasonably disturb, interfere with, or
endanger Landlord or any tenants of the Project.  Notwithstanding anything to the contrary contained in this Lease, promptly following receipt of written
notice  from  Landlord  that  another  tenant  or  occupant  of  the  Project  or  any  neighboring  property  is  experiencing  in  their  premises  an  unreasonable  or
excessive  infiltration  of  objectionable  or  unpleasant  odors,  smoke,  dust,  gas,  noise,  or  vibrations  from  the  Premises,  Landlord  may  investigate
same.  Following such investigation, to the extent it is determined that reasonably objectionable odors, smoke, dust, gas, noise, or vibrations have been found
to be infiltrating such other tenant's premises as a result of Tenant's use of (or operations in) the Premises, Tenant shall use all commercially reasonable, good
faith  efforts  to  remediate  and/or  minimize  the  ability  of  such  odors,  smoke,  dust,  gas,  noise,  or  vibrations  from  having  the  ability  to  enter  the  adjacent
premises.    In  addition,  Tenant  agrees  to  take  all  commercially  reasonable  measures,  at  Tenant's  sole  cost  and  expense,  in  accordance  with  plans  and
specifications reviewed and approved in advance by Landlord, including, without limitation, installing alterations and/or additional equipment at the Premises
to remediate the subject issues to the reasonable satisfaction of Landlord.  Except as otherwise expressly permitted by this Lease, outside storage, including
without limitation, storage of products, inventory or other personal property (other than the parking of operable trucks, vehicles, and trailers in compliance
with Legal Requirements and the Private Restrictions) is prohibited without Landlord's prior written consent.

(b)

Subject to Paragraphs 15  and  16  of  this  Lease  and  Landlord's  express  obligations  under  this  Lease,  including,  without
limitation, (i) Landlord's Construction Warranty, (ii) Landlord's obligations expressly set forth in Paragraph 10 below, and (iii) Landlord's obligations under
the Work Letter attached hereto as Exhibit B, Tenant, at its sole expense, shall comply with (A) all laws, including, without limitation, the Americans With
Disabilities  Act  (and  any  similar  statute),  orders,  judgments,  ordinances,  regulations,  codes,  directives,  permits,  licenses  (collectively,  "Legal
Requirements") and Tenant shall, at its expense, make any alterations or modifications within the Premises that are required by any Legal Requirements as a
result of Tenant's specific use of the Premises [i.e., other than Legal Requirements that apply generally to warehouse projects in the area] or any alterations
[including,  without  limitation,  any  Tenant-Made  Alterations],  improvements  [including,  without  limitation,  the  Tenant  Improvements]  or  other  work
performed by or on behalf of Tenant [exclusive of the Landlord Work], and (B) all declarations, covenants and restrictions (including, without limitation, [I]
that  certain  Declaration  of  Easements,  Covenants,  Conditions  and  Restrictions  recorded  on  June  10,  1997,  as  Instrument  No.  97141983  in  the  Official
Records of Alameda County, and [II] that certain Gateway Technology Centre Declaration of Covenants, Conditions and Restrictions recorded on June 10,
1997, as Instrument No. 97141984 in the Official Records of Alameda County, as either of the foregoing may be modified, amended, and/or supplemented
from time-to-time in accordance herewith), plats, and other matters of record applicable to the Premises (collectively, the "Private Restrictions"). Tenant will
not use or permit any of the Tenant Parties to use the Premises for any purpose or in any manner that would void Tenant's or Landlord's insurance, increase
the insurance risk, or cause the disallowance of any sprinkler credits.  If any increase in the cost of any insurance on the Premises or the Project is caused by
Tenant's use or occupation of the Premises, or because Tenant vacates the Premises, then Tenant shall pay the amount of such increase to Landlord.

(c)

Landlord  hereby  discloses  to  Tenant,  in  accordance  with  California  Civil  Code  Section  1938,  and  Tenant  hereby
acknowledges  that  the  Premises  have  not  undergone  an  inspection  by  a  Certified  Access  Specialist  (CASp)  to  determine  whether  the  Premises  meet  all
applicable construction-related accessibility standards pursuant to California Civil Code §55.51 et seq.  As required by Section 1938(e) of the California Civil
Code, Landlord hereby states as follows:  "A Certified Access Specialist (CASp) can inspect the subject premises and determine whether the subject premises
comply with all of the applicable construction-related accessibility standards under state law.  Although state law does not require a CASp inspection of the
subject premises, the commercial property owner or lessor may not prohibit the lessee or tenant from obtaining a CASp inspection of the subject premises for
the occupancy or potential occupancy of the lessee or tenant, if requested by the lessee or tenant.  The parties shall mutually agree on the arrangements for the
time and manner of the CASp inspection, the payment of the fee for the CASp inspection, and the cost of making any repairs necessary to correct violations
of construction-related accessibility standards within the premises."  In furtherance of the foregoing, and notwithstanding anything to the contrary contained
in  this  Lease,  Landlord  and  Tenant  hereby  agree  as  follows:  (i)  any  CASp  inspection  requested  by  Tenant  shall  be  conducted,  at  Tenant's  sole  cost  and
expense, by a CASp approved in advance by Landlord, subject to Landlord's rules and requirements; and (ii) Landlord shall have no obligation to perform any
work or repairs identified in any such CASp inspection.  

(d)

Tenant  and  its  employees  and  invitees  shall  have  the  non-exclusive  right  to  use,  in  common  with  others,  those  areas
outside of the Building within the Project that are intended for the use and enjoyment of all tenants and occupants of the Project (the "Common Areas"),
subject to modification from time-to-time and subject to such reasonable rules and regulations as Landlord may promulgate from time to time upon receipt of
written notice of the same from Landlord, so long as all such rules and regulations are enforced in a non-discriminatory manner.  Subject to compliance with
Legal Requirements, Tenant and the Tenant Party's shall have non-exclusive access to the Common Areas on a twenty-four (24) hour, seven (7) day per week
basis throughout the Lease Term; provided, however, Landlord shall at all times during the Lease Term have exclusive control of the Common Areas, and
may restrain or permit any use or occupancy of the Common Areas and/or may temporarily close any portion of the Common Areas for repairs, remodeling
and/or alterations, to prevent a public dedication or the accrual of prescriptive rights, or for any other reasonable purpose.  Landlord may also change the
shape and size of the Common Areas, add, eliminate or change the location of improvements to the Common Areas, including, without limitation, buildings,
parking areas, roadways and curb cuts.  Landlord shall maintain and operate the Common Areas in a manner consistent other institutional quality research and
development projects in the market area.

4.

Base Rent.  

(a)

Commencing on the Commencement Date, but subject to the Base Rent Credit (as defined in Paragraph 4(b) below), and
any credit under Paragraph 1(b)  above,  Tenant  shall  pay  Base  Rent  in  the  amounts  set  forth  in  the  Basic  Lease  Provisions,  in  advance,  without  demand,
deduction or set-off, except as otherwise expressly set forth in this Lease, on or before the first day of each calendar month.  The Prepaid Rent (as set forth in
the Basic Lease Provisions above) shall be due and payable on the date hereof (and shall be applied against Base Rent and Operating Expenses first due under
this  Lease).    Payments  of  Base  Rent  and  Operating  Expenses  for  any  fractional  calendar  month  shall  be  prorated.   All  payments  required  to  be  made  by
Tenant  to  Landlord  hereunder  shall  be  payable  at  such  address  as  Landlord  may  specify  from  time  to  time  by  written  notice  delivered  in  accordance
herewith.    The  obligation  of  Tenant  to  pay  Base  Rent  and  other  sums  to  Landlord  shall  constitute  rent  and  shall  be  independent  obligations  from  the
obligations of Landlord under this Lease.  Tenant shall have no right at any time to abate, reduce, or set-off any rent due hereunder except where expressly
provided to the contrary in this Lease. Tenant acknowledges that late payment by Tenant to Landlord of any rent due hereunder will cause Landlord to incur
costs  not  contemplated  by  this  Lease,  the  exact  amount  of  such  costs  being  extremely  difficult  and  impractical  to  determine.    Therefore,  if  Tenant  is
delinquent in any monthly installment of Base Rent or any monthly estimated Operating Expenses or any other sums due and payable hereunder for more
than  five  (5)  business  days  after  the  date  such  amount  is  due,  Tenant  shall  pay  to  Landlord  on  demand  a  late  charge  equal  to  five  percent  (5%)  of  such
delinquent  sum;  provided,  that  for  the  first  such  instance  of  delinquency  in  any  calendar  year,  such  late  charge  shall  not  be  due  unless  the  same  shall  be
delinquent for at least five (5) business days after receipt by Tenant of written notice of delinquency from Landlord.  The parties agree that such late charge
represents a fair and reasonable estimate of the costs that Landlord will incur by reason of such late payment by Tenant.  The late charge shall be deemed to
be  rent,  and  the  right  to  require  it  shall  be  in  addition  to  all  of  Landlord's  other  rights  and  remedies  for  a  payment  failure  of  Tenant,  including  without
limitation the right to charge interest on the past due amount.  

1111154v7

(b)

Subject to the terms and conditions of this Paragraph 4(b), provided that no Event of Default then exists under this Lease,
Tenant shall be credited with the payment of Base Rent with respect to the Premises for the second (2nd) through ninth (9th) full calendar months of Lease
Term only (collectively, the "Base Rent Credit"), in each case as and when the same becomes due and payable, for a total Base Rent Credit equal to One
Million Two Hundred Seventy-Three Thousand Two Hundred One and 20/100 Dollars ($1,273,201.20) in the aggregate.  Such Base Rent Credit shall not
reduce or limit any other amounts which are otherwise payable by Tenant under this Lease (including, without limitation, Operating Expenses).  If an Event of
Default then exists under this Lease at the time Tenant would otherwise be entitled to the Base Rent Credit, then the Base Rent Credit shall be suspended
during such period when the Event of Default is occurring (the aggregate amount of such suspended Base Rent Credit is referred to herein as the "Suspended
Base Rent Credit"), but if Tenant subsequently cures such Event of Default, then Landlord shall credit the aggregate amount of such Suspended Base Rent
Credit against the Base Rent next due and payable by Tenant under this Lease after the date of such cure.

5.

Letter of Credit.

(a)

As security for the full and faithful payment of all sums due under this Lease and the full and faithful performance of
every covenant and condition of this Lease to be performed by Tenant, concurrently with Tenant's execution of this Lease, Tenant shall deliver to Landlord a
letter of credit in the amount of Three Million Dollars ($3,000,000.00) (the "LC Amount") in favor of Landlord and effective immediately upon issuance (the
"Letter  of  Credit").    The  Letter  of  Credit  initially  delivered  pursuant  to  this  paragraph  and  all  substitutions,  replacements  and  renewals  of  it,  must  be
consistent with and shall satisfy all the following requirements: (i) the Letter of Credit shall be clean, irrevocable and unconditional; (ii) the Letter of Credit
must be issued by a national bank which is a member of the New York Clearing House, which bank must be reasonably satisfactory to Landlord; (iii) the
Letter of Credit shall have an expiration date no earlier than the first anniversary of the date of its issuance and shall provide for its automatic renewal from
year  to  year  unless  terminated  by  the  issuing  bank  by  notice  to  Landlord  given  not  less  than  sixty  (60)  days  prior  to  its  expiration  date  by  registered  or
certified mail (and the final expiration date of the Letter of Credit and all renewals of it shall be no earlier than sixty (60) days following the end of the Term);
(iv) the Letter of Credit may be drawn by facsimile, courier, or at the applicable banking office of the issuer and must allow for draws to be made pursuant to
a form of draw request which has been approved by Landlord; (v) the Letter of Credit must allow for one draw in the whole amount or multiple partial draws
(and Landlord shall not, as a condition to any draw, be required to deliver any certificate, affidavit or other writing to the issuer expressing the basis for the
draw; nor shall the issuer have the right to inquire as to the basis for the draw or require instruction or authorization from any party other than Landlord; nor
shall issuer be permitted to withhold a draw, when requested by Landlord, as a result of any instruction from any other party); (vi) the Letter of Credit shall be
freely transferable by Landlord; (vii) the Letter of Credit shall be governed by (A) the International Standby Practices (SP 98 published by the International
Chamber of Commerce and (B) the United Nations Convention on Independent Guarantees and Standby Letters of Credit; and (viii) the Letter of Credit shall
otherwise be in such form and shall be subject to such requirements as Landlord may require.  Landlord hereby approves First Republic Bank as the issuer of
the  Letter  of  Credit  should  Tenant  select  such  issuer.    Without  limiting  the  generality  of  the  foregoing,  the  Letter  of  Credit  must  be  issued  by  a  bank  or
financial institution acceptable to Landlord (x) that is chartered under the laws of the United States, any state thereof or the District of Columbia, and which is
insured by the Federal Deposit Insurance Corporation, and (y) whose long-term debt ratings on bank level senior debt obligations are rated by Fitch Ratings
Ltd. ("Fitch"),  Moody's  Investors  Service,  Inc.  ("Moody's")  and  Standard  &  Poor's  Ratings  Services  ("S&P")  or  their  respective  successors  (the  "Rating
Agencies") not less than A- from Fitch, Baa1 from Moody's or A- from S&P.

(b)

Landlord may draw on the Letter of Credit, in whole or in part at Landlord's election, without advance notice to Tenant at
any time or from time to time on or after (i) the occurrence of any Event of Default, or (ii) if Tenant, or anyone in possession of the Premises (or any portion
thereof) through Tenant, holds over after the expiration or earlier termination of this Lease, or (iii) Landlord is given notice by the issuer of the Letter of
Credit that it is terminating the Letter of Credit and Tenant has not provided a replacement Letter of Credit that satisfies the requirements of this Lease at least
thirty (30) days prior to such termination, or (iv) the Letter of Credit expires on a specified date by its terms and is not renewed or replaced at least thirty (30)
days  in  advance  of  its  expiration  date,  or  (iv)  to  the  extent  permitted  by  law,  in  the  event  any  bankruptcy,  insolvency,  reorganization  or  any  other  debtor
creditor proceeding is instituted by or against Tenant.  Tenant hereby waives the provisions of any law, now or hereafter in effect, which limits the manner in
which  Landlord  may  apply  sums  drawn  from  the  Letter  of  Credit,  it  being  agreed  that  Landlord  may  apply  such  amounts  towards  any  sums  reasonably
necessary to compensate Landlord

1111154v7

8

 
 
 
 
 
for any other loss or damage, foreseeable or unforeseeable, caused by the acts or omissions of Tenant or any officer, employee, agent, contractor or invitee of
Tenant. Tenant agrees and acknowledges that: (i) the Letter of Credit constitutes a separate and independent contract between Landlord and the issuing bank;
(ii) Tenant is not a third party beneficiary of such contract; and (iii) Tenant has no property interest whatsoever in the Letter of Credit or the proceeds thereof
and that, if Tenant becomes a debtor under any chapter of the Federal Bankruptcy Code, neither Tenant, any trustee, nor Tenant's bankruptcy estate shall have
any  right  to  restrict  or  limit  Landlord's  claim  and/or  rights  to  the  Letter  of  Credit  and/or  the  proceeds  thereof  by  application  of  Section  502(b)(6)  of  the
Federal Bankruptcy Code.

(c)

In addition, if at any time the bank or financial institution that issues the Letter of Credit is declared insolvent, or is placed
into receivership by the Federal Deposit Insurance Corporation or any other governmental or quasi-governmental institution, or if there is a material adverse
change  in  the  financial  or  business  condition  of  the  bank  or  financial  institution  from  the  date  of  this  Lease,  as  reasonably  determined  by  Landlord,  then
following written notice from Landlord, Tenant shall have ten (10) days to replace the Letter of Credit with a new letter of credit from a bank or financial
institution reasonably acceptable to Landlord.  If Tenant does not replace the Letter of Credit with a new letter of credit from a bank or financial institution
reasonably  acceptable  to  Landlord  within  such  ten  (10)  day  period,  then  notwithstanding  anything  to  the  contrary  herein,  Landlord  may  treat  the  same  as
Event of Default after the expiration of the applicable notice and cure period provided in this Lease, and Landlord shall have the right to draw upon the Letter
of Credit for the full amount of the Letter of Credit, and such amount shall be held by Landlord for application, at Landlord's election, to future sums owing to
Landlord under the Lease, in such order and priority as Landlord elects in its absolute discretion.

(d)

Landlord may apply any sum drawn on the Letter of Credit to amounts owing to Landlord under this Lease in such order
and priority as Landlord elects in its absolute discretion.  If any of the proceeds drawn on the Letter of Credit are not applied immediately to sums owing to
Landlord under this Lease, Landlord may retain any such excess proceeds for application, at Landlord's election, to future sums owing to Landlord under this
Lease,  in  such  order  and  priority  as  Landlord  elects  in  its  absolute  discretion.    Any  unused  proceeds  need  not  be  segregated  from  Landlord's  other
assets.  Tenant shall, within ten (10) days after Landlord's demand, restore the amount of the Letter of Credit drawn so that the Letter of Credit is restored to
the original amount of the Letter of Credit.  If Tenant does not restore the Letter of Credit to its original amount within the required time period, such non-
restoration shall be considered an Event of Default.  If Tenant restores the Letter of Credit to its original amount in accordance with the terms and conditions
contained herein, then Landlord shall promptly return to Tenant the amounts previously drawn and not yet applied by Landlord.

(e)

Additionally, Landlord's draw and application of all or any portion of the proceeds of the Letter of Credit shall not impair
any other rights or remedies provided under this Lease or under applicable law and shall not be construed as a payment of liquidated damages.  If no Event of
Default exists under this Lease, the Letter of Credit shall be returned to Tenant or, if Landlord has drawn on the Letter of Credit, the remaining proceeds of the
Letter  of  Credit  which  are  in  excess  of  sums  due  the  Landlord  shall  be  repaid  to  Tenant,  without  interest,  within  thirty  (30)  days  after  the  expiration  or
termination of the Lease Term, delivery of possession of the Premises by Tenant to Landlord in accordance with this Lease, and the satisfaction by Tenant of
all of its obligations under the Lease.  On any request by Landlord made during the Lease Term, Tenant shall cooperate in accomplishing any reasonable
modification of the Letter of Credit requested by Landlord, at Landlord's cost.  If the Letter of Credit should be lost, mutilated, stolen or destroyed, Tenant
shall cooperate in obtaining the issuance of a replacement.

(f)

Notwithstanding anything to the contrary contained herein, Landlord and Tenant acknowledge and agree that in no event
or circumstance shall the Letter of Credit or any renewal thereof or any proceeds thereof be (i) deemed to be or treated as a "security deposit" within the
meaning of California Civil Code Section 1950.7, (ii) subject to the terms of such Section 1950.7, or (iii) intended to serve as a "security deposit" within the
meaning of such Section 1950.7.  The parties hereto (A) recite that the Letter of Credit is not intended to serve as a security deposit and such Section 1950.7
and  any  and  all  other  laws,  rules  and  regulations  applicable  to  security  deposits  in  the  commercial  context  ("Security  Deposit  Laws")  shall  have  no
applicability  or  relevancy  thereto,  and  (B)  waive  any  and  all  rights,  duties  and  obligations  either  party  may  now  or,  in  the  future,  will  have  relating  to  or
arising from the Security Deposit Laws.

(g)

Tenant shall not assign or grant any security interest in the Letter of Credit and any attempt to do so shall be void and of

(h)

In the event of a sale or transfer of Landlord's estate or interest in the Premises, Landlord shall have the right to transfer
the Letter of Credit to the vendee or the transferee, Landlord shall be responsible for paying the first $5,000.00 of any transfer fees charged by the issuing
bank, and Tenant  shall  pay  any  transfer  fees  charged  by  the  issuing  bank  in  excess  of  $5,000.00,  and  upon  the  transferee's  receipt  of  the  Letter  of  Credit
Landlord shall thereafter be considered released by Tenant from all liability for the return of the Letter of Credit.  Tenant shall cooperate in effecting such
transfer.

(i)

No mortgagee or purchaser of any or all of the Premises at any foreclosure proceeding brought under the provisions of any
mortgage shall (regardless of whether the Lease is at the time in question subordinated to the lien of any mortgage) be liable to Tenant or any other person for
any or all amounts drawn against the Letter of Credit or any other payment made by Tenant under the provisions of this Lease), unless Landlord has actually
delivered it in cash to such mortgagee or purchaser, as the case may be.

(j)

Notwithstanding anything to the contrary contained in this Lease, provided that (i) no Event of Default occurs or exists,
and (ii) Tenant is able to adequately prove to Landlord that Tenant’s operations for the calendar year prior to the applicable “Reduction Date” (as specified
below)  have  yielded  at  least  Seventy-Five  Million  Dollars  ($75,000,000.00)  in  cash,  as  reported  in  Tenant’s  10-K,  or  if  a  10-K  is  not  available,  financial
statements prepared in accordance with generally accepted accounting principles and certified by a responsible officer of Tenant (collectively, the "Reduction
Conditions"), then the LC Amount shall be reduced in accordance with the following schedule (which reductions shall not be effectuated, and shall not be
effective, unless and until Landlord has confirmed in writing that the Reduction Conditions have been satisfied, which confirmation shall not be unreasonably
withheld,  conditioned  or  delayed).   Any  reduction  of  the  LC  Amount  may  be  effectuated  either  via  an  amendment  to  the  existing  Letter  of  Credit  or  a
replacement Letter of Credit.

Tenant agrees and acknowledges that the foregoing LC Amount reduction schedule is conditioned upon the Reduction Conditions being satisfied as of each
applicable Reduction Date.  If the Reduction Conditions are not satisfied as of a particular Reduction Date, then the LC Amount shall not be reduced on such
Reduction Date; provided, however, Tenant shall have the ability to “catch-up” on the LC Amount reduction schedule during the Lease Term provided the
Reduction Conditions are satisfied on the subsequent Reduction Date.  By way of example and not of limitation, if at the end of the thirty-sixth (36th) full
calendar month of the initial Lease Term the Reduction Conditions are not

1111154v7

10

 
 
 
 
 
 
 
 
 
satisfied, then, without limiting any of Landlord's other rights and remedies under this Lease and/or at law and/or in equity in connection with same, the LC
Amount shall not be reduced and shall remain at $2,800,000.00.  However, if at the end of the forty-eighth (48th) full calendar month of the initial Lease
Term, the Reduction Conditions are satisfied, then the LC Amount shall be reduced to $2,400,000.00 in accordance with the above schedule.  The LC Amount
shall continue to be reduced in accordance with the foregoing schedule until the LC Amount equals $1,000,000.00, at which point the LC Amount shall no
longer be reduced and shall remain at such amount until the expiration or earlier termination of the Lease Term. Tenant further agrees and acknowledges that
no  reduction  of  the  LC  Amount  shall  be  effective  until  Landlord  has  confirmed  in  writing  that  the  Reduction  Conditions  have  been  satisfied  as  of  the
applicable  Reduction  Date,  which  confirmation  Landlord  shall  not  be  unreasonably  withhold,  condition  or  delay.      If  the  LC  Amount  gets  reduced  in
accordance with the terms and conditions contained herein and the reduction schedule above, it shall not be subject to increase thereafter.  Tenant shall not be
entitled to reduce the LC Amount except as expressly set forth in this Paragraph 5(j).

Notwithstanding  the  foregoing  to  the  contrary,  provide  no  Event  of  Default  exists,  in  the  event  that  Tenant  maintains  a  reasonably  verifiable
tangible  net  worth  exceeding  One  Billion  Dollars  ($1,000,000,000.00)  (the  "Net  Worth  Requirement"),  then  Tenant  may  reduce  the  LC  Amount  to
$247,950.75 not earlier than the thirtieth (30th)  day  following  delivery  of  written  notice  to  Landlord  that  Tenant  has  satisfied  the  Net  Worth  Requirement
together with financial statements evidencing the fact that such Net Worth Requirement has been satisfied. If Tenant is a corporation with publicly traded
securities or is otherwise required to file financial statements with the Securities and Exchange Commission, the public filing of such financial statements
shall be deemed to satisfy the requirement to provide evidence of Tenant’s net worth.  Alternatively, Tenant shall provide Landlord with a copy of Tenant’s
most  current  quarterly  and  annual  financial  reports,  certified  by  an  officer  of  the  company.  Tenant  agrees  and  acknowledges  that  no  reduction  of  the  LC
Amount  pursuant  to  this  paragraph  shall  be  effective  until  Landlord  has  confirmed  in  writing  that  the  Net  Worth  Requirement  has  been  satisfied,  which
confirmation  Landlord  shall  not  be  unreasonably  withhold,  condition  or  delay.  Landlord  shall  have  the  right  to  disallow  Tenant's  option  to  reduce  the  LC
Amount as permitted in this subparagraph, and to require Tenant to increase the LC Amount to the applicable amounts required by the schedule above if, at
any time during the Lease Term, Tenant cannot reasonably demonstrate that it satisfies the Net Worth Requirement.

Operating Expense Payments.

(a)

Commencing on the Commencement Date, during each month of the Lease Term, on the same date that Base Rent is due
(and on the first day of each month during the Base Rent Credit period), Tenant shall pay Landlord an amount equal to 1/12th of the annual cost, as estimated
by  Landlord  from  time-to-time,  of  Tenant's  Proportionate  Share  (as  defined  in  the  Basic  Lease  Provisions)  of  the  amount  of  Operating  Expenses  for  the
Premises and/or the Project. Payments thereof for any fractional calendar month shall be prorated.  Subject to the terms of this Lease, Tenant's obligation to
pay for Operating Expenses arising or pertaining to periods during the Lease Term shall survive the expiration or earlier termination of the Lease.

(b)

The term "Operating Expenses" means all costs and expenses incurred by Landlord in connection with the ownership,
maintenance, and/or operation of the Premises and/or the Project, including, but not limited to costs of: utilities (other than those paid for directly to utility
providers  by  Tenant  or  by  other  tenants  of  the  Project);  maintenance  repair  and  replacement  of  all  portions  of  the  Premises  and/or  the  Project,  including
without limitation, paving and parking areas, roads, roofs (excluding the portions comprising the Building Structural Elements, as defined in Paragraph 10
below),  roof  membranes,  alleys,  and  driveways;  mowing,  snow  removal,  landscaping,  and  exterior  painting;  the  cost  of  maintaining  utility  lines  and
equipment, fire sprinklers and fire protection systems, exterior lighting and mechanical and building systems serving the Building or Project; amounts paid to
contractors and subcontractors for work or services performed in connection with any of the foregoing; the cost of any insurance premium and deductible for
insurance maintained by Landlord with respect to the Premises and Project, which deductibles shall be commercially reasonable based on the deductibles of
institutional owners of commercial properties similar to the Project in the market in which the Project is located, Tenant's Proportionate Share of which shall
not exceed $50,000.00 per occurrence in "Current Dollars" (as defined in Paragraph 37(p) below) (provided, however, such $50,000.00 cap shall not apply to
any deductible for earthquake insurance [which is addressed separately in Paragraph 6(c) below]); charges or assessments of any association to which the
Premises and/or the Project is subject; costs incurred in connection with any declarations, covenants, conditions or restrictions affecting

1111154v7

11

 
 
 
 
 
 
the Project; fees payable to tax consultants and attorneys for consultation and contesting taxes (not to exceed the amount of tax benefit Landlord reasonably
expected to achieve in connection with any such contest); environmental audits; property management and accounting fees payable to a property manager,
including  any  affiliate  of  Landlord,  provided  that  Tenant's  Proportionate  Share  of  the  property  management  fees  shall equal one and  fifty  one  hundredths
percent (1.50%) of the gross revenue of the Premises (which gross revenues shall include Base Rent [without regard to any credit or abatement of Base Rent,
including, without limitation, the Base Rent Credit, as if Base Rent was payable during such period] and all Operating Expenses); security services, if any;
trash  collection,  sweeping  and  removal;  and  Includable  Capital  Expenditures  (as  defined  below),  provided  that  the  cost  of  such  Includable  Capital
Expenditures that  are  required  to  be  capitalized  for  federal  income  tax  purposes  shall be amortized on  a  straight  line  basis  over  the  useful  life  thereof  (as
determined  in  accordance  with  customary  and/or  generally  accepted  real  estate  management  accounting  practices  and  principles),  together  with  interest
thereon, and the amortized portion of the costs shall be included in Operating Expenses only to the extent of the amortized amount applicable to the respective
calendar year.  In addition, Operating Expenses shall include (1) Taxes (hereinafter defined) assessed or pertaining to each calendar year (or portion thereof)
during the Lease Term, and (2) the cost of insurance maintained by Landlord for the Premises and/or the Project for each calendar year during the Lease
Term.    If  less  than  one  hundred  percent  (100%)  of  the  net  rentable  area  of  the  Project  is  occupied  by  tenants  at  all  times  during  any  calendar  year,  then
Operating Expenses that vary with occupancy or use for such year shall include all additional costs and expenses that Landlord reasonably determines would
have  been  incurred  had  one  hundred  percent  (100%)  of  the  Project  been  occupied  at  all  times  during  such  year  by  tenants.    For  purposes  of  this  Lease,
"Includable  Capital  Expenditures"  means  the  costs  of  capital  repairs,  replacements,  alterations,  improvements  to  the  extent  such  expenses  are:  (a)
reasonably intended to effect economies in the operation or maintenance of the Building and/or the Project, and/or are anticipated to reduce current or future
Operating Expenses, in each case to the extent of reasonably anticipated by Landlord; (b) required to comply with Legal Requirements or Private Restrictions
that are first enacted after the date of Substantial Completion of the Landlord Work or to comply with existing Legal Requirements or Private Restrictions that
are modified, amended, or subject to new or different interpretation(s) after the date of Substantial Completion of the Landlord Work; and/or (c) commercially
reasonable in connection with Landlord's maintaining and repairing the Building in accordance with the  provisions  of  this  Lease  (subject to the terms and
conditions of Paragraph 10 below with respect to Building Structural Elements which are to be maintained and repaired by Landlord) and/or  the  Common
Areas of the Project in a manner consistent with other institutional quality research and development projects in the market area.

(c)

Notwithstanding  the  foregoing,  Operating  Expenses  shall  not  include:  (1)  debt  service  (including  interest,  depreciation
and  principal  payments)  on  any  indebtedness,  any  financing  or  refinancing  costs,  or  ground  rent  under  ground  leases;  (2)  costs  of  restoration  and  costs
incurred in connection with any casualty or condemnation action (provided, however, Tenant shall be responsible for its Proportionate Share of any deductible
under  insurance  policies  maintained  by  Landlord,  which  Proportionate  Share  of  such  deductible(s)  shall  not  exceed  $50,000.00  per  occurrence  in  Current
Dollars; provided, however, such $50,000.00 cap shall not apply to any deductible for earthquake insurance [which is addressed separately below]), in each
case  to  the  extent  Landlord  is  reimbursed  by  insurance  or  condemnation  proceeds  (or  to  the  extent  Landlord  would  have  been  reimbursed  had  Landlord
carried the insurance required to be carried by Landlord pursuant to this Lease); (3) leasing commissions, advertising and promotional expenses, or the costs
of  renovating  space,  for  other  tenants;  (4)  any  "tenant  allowances,"  "tenant  concessions"  and  other  costs  or  expenses  incurred  in  fixturing,  furnishing,
renovating or otherwise improving, decorating or redecorating space for other tenants or other occupants of the Project, except in connection with general
maintenance and repairs to the Project in general; (5) fines, penalties, and interest due to Landlord's failure to make timely payments of its obligations (unless
resulting from Tenant's failure to timely perform any of its obligations under this Lease, in which case Tenant shall be responsible for such fines, penalties and
interest);  (6)  costs  associated  with  the  operation  of  the  business  of  the  entity  which  constitutes  "Landlord"  (as  distinguished  from  the  costs  of  operating,
maintaining, repairing and managing the Building and the Project) including, but not limited to, Landlord's or Landlord's managing agent's general corporate
overhead  and  general  administrative  expense  (including  corporate  organizational  expenses  and  accounting  fees)  and  costs,  including  interest,  of  selling,
syndicating,  financing,  mortgaging  or  hypothecating  any  of  the  Landlord's  interest  in  the  Building  and/or  the  Project;  (7)  overhead  and  profit  paid  to
subsidiaries or affiliates of Landlord for management or other services for supplies or other materials to the extent the amounts incurred are in excess of those
which would have been reasonably incurred if such supplies or services were obtained from unrelated third parties (but this provision does not prevent the
payment of a management fee as permitted in Paragraph 6(b) of the Lease); (8) costs to the extent Landlord is reimbursed by Landlord's insurance carrier or
any other tenant's insurance carrier, by warranty proceeds, or from any third parties; (9) reserves for future

1111154v7

12

 
 
 
 
expenses beyond expenses anticipated for the then current year; (10) any bad debt loss, rent loss, or reserves for bad debts or rent loss; (11) the wages and
benefits of any employee who does not devote substantially all of his or her employed time to the Project unless such wages and benefits are prorated to
reflect time spent on operating and managing the Project vis-à-vis time spent on matters unrelated to operating and managing the Project; (12)  utilities  for
which  Tenant  directly  contracts  with  the  local  public  service  company  to  the  extent  the  same  would  result  in  a  duplication  in  charges  to  Tenant;  (13)
Landlord's  political  or  charitable  contributions; (14)  costs  incurred  to  remove  and/or  remediate  Pre-existing Hazardous  Materials  and/or  Landlord  Caused
Hazardous  Materials  (as  defined  in Paragraph 30 below)  from  the Premises,  Building  or  Project;  (15)  costs  of  repair,  maintenance  or  replacement  of  the
"Building Structural Elements" (as defined in Paragraph 10 below) that are expressly required in Paragraph 10 to be performed at Landlord's sole cost and
expense; (16) the expense of service provided to other tenants in the Project for which Landlord is entitled to be reimbursed by such tenants as an additional
charge in excess of minimum rental other than reimbursement of such tenant's share of Operating Expenses; and (17) the cost of any premiums or deductibles
for earthquake insurance coverage to the extent materially in excess of the cost of premiums or deductibles for earthquake insurance coverage carried by other
institutional owners of commercial properties similar to the Project in the market in which the Project is located.  

(d)

By April 30th of each year (and as soon as reasonably practical after the expiration or termination of this Lease), Landlord
shall  provide  Tenant  with  a  reasonably  detailed  statement  of  actual  Operating  Expenses  for  the  preceding  calendar  year  or  part  thereof  (the  "Actual
Statement").    If  Tenant's  total  payments  of  estimated  Operating  Expenses  for  any  year  are  less  than  Tenant's  Proportionate  Share  of  actual  Operating
Expenses for such year, then Tenant shall pay the difference to Landlord within thirty (30) days after written demand, and if more, Landlord shall credit to
Tenant the difference to Operating Expenses next becoming due under this Lease, or if Tenant provides a written notice to Landlord requesting same, refund
the difference to Tenant within thirty (30) days of such request.  For purposes of calculating Tenant's Proportionate Share of Operating Expenses, a year shall
mean a calendar year except the first year, which shall begin on the Commencement Date, and the last year, which shall end on the expiration of this Lease.
Landlord shall not have any obligation to credit or pay to Tenant any amounts under this subsection (d) during any period that an Event of Default exists.
Tenant's and Landlord's payment obligations under this subparagraph (d) shall survive the expiration or any termination of this Lease. Notwithstanding the
immediately preceding sentence, if Landlord fails to charge Tenant for any particular item of Operating Expenses within two (2) years after the end of any
calendar year for which such Operating Expense is applicable, Landlord shall be deemed to have forfeited the right to bill Tenant for such particular item of
Operating Expense with respect to such calendar year (except to the extent of any Operating Expenses relate to supplemental taxes or assessments attributable
to such calendar year which were not reasonably known to Landlord during the calendar year in question, for which no such limitation shall apply).

(e)

With respect to Operating Expenses which Landlord allocates to the entire Project, Tenant's "Proportionate Share" shall
be the percentage set forth on the first page of this Lease as Tenant's Proportionate Share of the Project as reasonably adjusted by Landlord in the future for
changes in the physical size of the Premises or the Project; and, with respect to Operating Expenses which Landlord allocates only to the Building, Tenant's
"Proportionate Share" shall be the percentage set forth on the first page of this Lease as Tenant's Proportionate Share of the Building as reasonably adjusted
by  Landlord  in  the  future  for  changes  in  the  physical  size  of  the  Premises  or  the  Building.    Provided  that  Landlord  does  the  same  on  a  commercially
reasonable basis, Landlord may equitably increase Tenant's Proportionate Share for any item of expense or cost reimbursable by Tenant that relates to a repair,
replacement, or service that benefits only the Premises or only a portion of the Project or Building that includes the Premises or that varies with occupancy or
use.    The  estimated  Operating  Expenses  for  the  Project  set  forth  on  the  first  page  of  this  Lease  are  estimates  only,  and  Landlord  makes  no  guaranty  or
warranty that such estimates will be accurate.

(f)

Tenant may, within one hundred eighty (180) days after any Actual Statement is delivered, request a copy of the relevant
supporting data related to the Operating Expenses and the Actual Statement. Landlord shall make all pertinent books and records available for inspection that
are reasonably necessary for Tenant to conduct its review. Tenant shall have the right, not more than once per each period covered by each Actual Statement,
to cause a Qualified Person (as defined below) to review and audit the relevant supporting data for any portion of an Actual Statement delivered by Landlord,
in accordance with the following procedure:

1111154v7

13

 
 
 
 
(1)

Tenant shall, within one hundred eighty (180) days after  any  Actual  Statement  is  delivered,  deliver  a  written
notice to Landlord indicating that Tenant desires to audit the Actual Statement. Tenant shall promptly provide to Landlord a copy of its review. If
Tenant's review determines that actual Operating Expenses for the subject calendar year are less than reported, Landlord shall, unless Landlord
disagrees (in which case the process described in clause (3) below shall be followed) provide to Tenant a credit against Operating Expenses then
coming due under this Lease (or refund such amount if Tenant provides a written notice to Landlord requesting such a refund) the amount of the
overpayment by Tenant. Likewise, if Tenant's review determines that Operating Expenses for the subject calendar year are greater than reported,
Tenant shall pay Landlord the amount of any underpayment within thirty (30) days after such determination.  In no event shall Tenant be entitled
to withhold, deduct, or offset any monetary obligation of Tenant to Landlord under the Lease (including without limitation, Tenant's obligation to
make  all  payments  of  rent  and  all  payments  of  Tenant's  Operating  Expenses)  pending  the  completion  of  and  regardless  of  the  results  of  any
review of records under this Paragraph. The right of Tenant under this Paragraph may only be exercised once for any Actual Statement, and if
Tenant  fails  to  meet  any  of  the  above  conditions  as  a  prerequisite  to  the  exercise  of  such  right,  the  right  of  Tenant  under  this  Paragraph  for  a
particular Actual Statement shall be deemed waived.  

(2)

Any  review  of  records  under  this  Paragraph  shall  be  at  the  sole  expense  of  Tenant  (except  as  otherwise
expressly provided herein) and shall be conducted by a Qualified Person.  Tenant acknowledges and agrees that any records reviewed under this
Paragraph constitute confidential information of Landlord, which shall not be disclosed to anyone other than the Qualified Person performing the
review, the principals of Tenant who receive the results of the review, and Tenant's attorneys and accounting employees.  The disclosure of such
information to any other person, whether or not caused by the conduct of Tenant, shall constitute a material breach of this Lease  

(3)

Any  errors  disclosed  by  the  review  shall  be  promptly  corrected  by  Landlord,  provided,  however,  that  if
Landlord  disagrees  with  any  such  claimed  errors,  Landlord  shall  have  the  right  to  cause  another  review  to  be  made  by  a  Qualified  Person  at
Landlord's  cost.    In  the  event  of  a  disagreement  between  the  two  (2)  reviews,  the  two  (2)  Qualified  Persons  who  conducted  Landlord's  and
Tenant's reviews shall jointly designate a third (3rd)  Qualified  Person,  at  Tenant's  sole  cost  and  expense  (except  as  otherwise  indicated  in  this
Lease), to conduct a review of Landlord's records.  The review of such third (3rd) Qualified Person shall be deemed correct and binding upon the
parties.  In the event that the final results of such review of Landlord's records reveal that Tenant has overpaid by more than five percent (5%),
then Landlord shall pay, up to a maximum of $10,000.00 in the aggregate, the reasonable out-of-pocket cost of the review of Landlord's records
by Tenant's Qualified Person and the reasonable out-of-pocket cost of the review of Landlord's records by the third (3rd) Qualified Person. In the
event that the final results of such review of Landlord's records reveal that Tenant has overpaid by five percent (5%) or less, then Tenant shall pay,
up to a maximum of $10,000.00 in the aggregate, the reasonable out-of-pocket cost of the review of Landlord's records by Landlord's Qualified
Person and the reasonable out-of-pocket cost of the review of Landlord's records by the third (3rd) Qualified Person.  In the event that such results
show that Tenant has underpaid or overpaid its obligations for a preceding period, the amount of such underpayment or overpayment shall be paid
by  Tenant  or  Landlord,  as  applicable,  as  provided  in  Paragraph  6(f)(1)  above.    A  "Qualified  Person"  means  an  accountant  or  other  person
(including, without limitation, an employee of Tenant) experienced in accounting for income and expenses of industrial projects engaged solely
on  terms  which  do  not  entail  any  compensation  based  or  measured  in  any  way  upon  any  savings  in  rent  or  reduction  in  Operating  Expenses
achieved through the inspection process.

(g)

Notwithstanding  the  foregoing,  for  purposes  of  determining  Operating  Expenses  payable  by  Tenant  under  this  Lease
during  the  Lease  Term  only,  Controllable  Operating  Expenses  (defined  below)  for  the  second  full  calendar  year  of  the  Lease  Term,  and  each  subsequent
calendar year of the Lease Term shall not exceed the Controllable Operating Expense Cap (defined below) for such calendar year.  The term "Controllable
Operating Expense Cap" shall mean, with respect to the second full calendar year of the initial Lease Term, one hundred six percent (106%) of the amount
of Controllable Operating Expenses with respect to the first full calendar year of the initial Lease Term, and with respect to each subsequent calendar year
during the initial Lease Term, the Controllable Operating Expense Cap shall increase by six percent (6%) over the applicable Controllable Operating Expense
Cap for the immediately preceding calendar year (irrespective of whether the actual Controllable Operating Expenses for

1111154v7

14

 
 
 
 
the preceding calendar year was less than the amount of the applicable Controllable Operating Expense Cap for such preceding calendar year), such increase
to be cumulative and compounded annually.  For illustrative purposes only, if the amount of Controllable Operating Expenses during the first full calendar
year of the initial Lease Term was $100 per month, then the Controllable Operating Expense Cap for the second full calendar year of the initial Lease Term
would be $106.00 per month, the Controllable Operating Expense Cap for the third full calendar year of the initial Lease Term would be $112.36 per month,
and so on, and such increases in the Controllable Operating Expense Cap shall occur irrespective of whether the actual Controllable Operating Expenses in
any calendar year are less than the Controllable Operating Expense Cap.  For purposes of this Lease, "Controllable Operating Expenses" shall mean and
refer to all Operating Expenses set forth in this Paragraph 6, except for the following: (i) Taxes; (ii) insurances costs and charges; (iii) the cost of all charges
for electricity, gas, water and other utilities; (iv) snow and ice removal costs; (v) increased or additional costs resulting from events of Force Majeure; (vi)
charges or assessments of any association to which the Premises is subject; and (vii)  any  costs  resulting  from  the  expiration  of  a  warranty;  provided  that,
notwithstanding anything to the contrary contained herein, the foregoing shall not limit Tenant's obligations to (I) pay to Landlord the amortized payments of
any  capital  expenditures  and  repairs  made  by  Landlord  pursuant  to  this  Lease,  (II)  reimburse  Landlord  for  the  costs  incurred  by  Landlord  under  any
maintenance  service  contracts,  if  Landlord  elects  to  maintain  and  repair  the  HVAC  systems  and  other  mechanical  and  building  systems  as  set  forth  in
Paragraph 11  of  this  Lease,  or  (III)  reimburse  Landlord  for  costs  associated  with  the  removal  and/or  remediation  of  Hazardous  Materials  to  the  extent  of
Tenant's  payment  obligations  under  Paragraph 30  of  this  Lease  (i.e.,  each  of  (I), (II)  and  (III)  shall  not  be  subject  to  the  Controllable  Operating  Expense
Cap).         

7.

Utilities.

(a)

Tenant  shall  contract  with  and  timely  pay  during  the  Lease  Term  for  all  water,  gas,  electricity,  heat,  light,  power,
telephone, sewer, sprinkler services, refuse and trash collection, and other utilities and services used on the Premises, all maintenance charges for utilities, and
any  storm  sewer  charges  or  other  similar  charges  for  utilities  imposed  by  any  governmental  entity  or  utility  provider,  together  with  any  taxes,  penalties,
surcharges or the like pertaining to Tenant's use of the Premises.  Landlord shall have no responsibilities whatsoever in connection with the foregoing.  Tenant
acknowledges  and  agrees  that  Landlord  may  not  be  able  to  obtain  separate  meters  for  certain  utilities  including,  without  limitation,  irrigation  and  storm
water.  Tenant shall pay its share of all charges for jointly metered utilities based upon consumption, as reasonably determined by Landlord.  Tenant agrees to
limit use of water and sewer for normal restroom use or other uses consistent with the Permitted Use of the Premises.  No interruption or failure of utilities or
other essential services shall result in the termination of this Lease or the abatement of rent; provided, however, if (I) Tenant is prevented from using, and does
not use, the Premises or a portion thereof, as a result of any interruption in utilities or other essential services that Landlord is obligated to provide pursuant to
the express terms of this Lease, and (II) such interruption is caused by Landlord's negligence or breach of its express obligations under this Lease, and (III)
the cure of such interruption is within Landlord's reasonable control (such interruption that satisfies (I), (II) and (III) above shall be referred to herein as an
"Abatement Event"), then Tenant shall give written notice of such Abatement Event to Landlord.  If, and only if, the Abatement Event persists for more than
five (5) consecutive business days after Landlord's receipt of Tenant's written notice of such Abatement Event, then Base Rent and Tenant's Proportionate
Share of Operating Expenses shall be abated (proportionally if the Abatement Event only prevents Tenant from using a portion of the Premises) commencing
on the sixth (6th) consecutive business day following Landlord's receipt of notice of the Abatement Event for such period of time that Tenant continues (as a
result of the Abatement Event) to be so prevented from using, and does not use, the Premises or a portion thereof, in proportion that the rentable area of the
portion of the Premises that Tenant is prevented from using, and does not use, bears to the total rentable area of the Premises.

used on or for the Premises.  Landlord shall have no obligations whatsoever in connection therewith.  

(b)

Tenant shall, at its sole cost and expense, contract directly with a janitorial service and shall pay for all janitorial services

(c)

Notwithstanding anything to the contrary contained in this Lease, Tenant agrees that Landlord, at its election, may contact
any  utility  company  providing  utility  services  to  the  Premises  in  order  to  obtain  data  on  the  energy  being  consumed  by  the  occupant  of  the
Premises.  Furthermore, Tenant agrees to provide Landlord with Tenant's energy consumption data within thirty (30) days after Landlord's request for the
same.  Tenant acknowledges that pursuant to applicable Legal Requirements, Landlord may be required to disclose information concerning Tenant's energy
usage at the Building to certain third parties, including, without limitation, prospective

1111154v7

15

 
 
 
 
purchasers,  lenders  and  tenants  of  the  Building  (the  "Tenant  Energy  Use  Disclosure").    Tenant  hereby  (A)  consents  to  all  such  Tenant  Energy  Use
Disclosures, and (B) acknowledges that Landlord shall not be required to notify Tenant of any Tenant Energy Use Disclosure.  Tenant agrees to take such
further actions as are reasonably necessary in order to further the purpose of this paragraph, including, without limitation, providing to Landlord the names
and contact information for all utility providers serving the Premises, copies of utility bills, written authorization from Tenant to any such utility company to
release information to Landlord, and any other relevant information reasonably requested by Landlord or the applicable utility company.

8.

Taxes.    Landlord  shall  pay  all  taxes,  assessments,  special  assessments,  improvement  districts,  and  governmental  charges  that  are
payable with respect to the Project (including, without limitation, Tenant's Proportionate Share of any Common Areas within the Project) and applicable to
any period during the Lease Term (collectively referred to as "Taxes"), including without limitation (i) any license fee, rental tax, levy charge, assessment, or
penalty  imposed  by  any  taxing  authority  against  the  Project  (but  only  to  the  extent  such  penalties  are  attributable  to  Tenant's  failure  to  timely  pay  Taxes
hereunder);  (ii)  any  tax  on  the  Landlord's  right  to  receive,  or  the  receipt  of,  rent  or  income  from  the  Project  or  against  Landlord's  business  of  leasing  the
Project  or  in  connection  with  Landlord's  business  of  owning  and/or  leasing  space  in  the  Project  which  are  now  or  hereafter  levied  or  assessed  against
Landlord by the United States of America, the State of California or any political subdivision, public corporation, district or other political or public entity;
(iii) water and sewer charges, any tax or charge for fire protection, streets, sidewalks, road maintenance, refuse or other services provided to (or for the benefit
of)  the  Project  by  any  governmental  agency;  (iv)  any  tax  imposed  upon  this  transaction  or  based  upon  a  re-assessment  of  the  Project  due  to  a  change  of
ownership, as defined by applicable law, or based upon a re-assessment of the Project due to any other transfer of all or part of Landlord's interest in the
Project; (v) gross receipt taxes; (vi) any fees, taxes or assessments against, or as a result of, any tenant improvements installed on the Premises by or for the
benefit of Tenant, and (vii) any charge or fee replacing any tax previously included within the definition of Taxes.  Taxes that are applicable to any period
during  the  Lease  Term  shall  be  included  as  part  of  the  Operating  Expenses  charged  to  Tenant  pursuant  to  Paragraph  6  hereof,  based  upon  Landlord's
reasonable  estimate  of  the  amount  of  Taxes,  and  shall  be  subject  to  the  terms  and  conditions  of  Paragraph  6,  above,  including,  without  limitation,  the
reconciliation and adjustment procedures thereof once the actual amount of Taxes is known. Taxes shall include, without limitation, any increase in any of the
foregoing  based  upon  construction  of  improvements  on  the  Project  or  changes  in  ownership  (as  defined  in  the  California  and  Revenue  Taxation  Code).
Tenant's  Proportionate  Share  of  Taxes  may  be  equitably  increased  if  Landlord  determines  in  its  reasonable  discretion  that  Tenant's  improvements  and/or
alterations increases Taxes for the Project in excess of Tenant's Proportionate Share of the Project; provided, however, that Landlord shall provide Tenant with
prior  written  notice  and  reasonable  supporting  documentation  of  such  basis  for  such  increase.    Further,  Taxes  shall  not  include:  (I)  taxes  and  assessments
attributable to Landlord's federal, state or local income taxes; (II) penalties or interest other than those attributable to Tenant's failure to timely pay Taxes or to
otherwise  comply  with  its  obligations  under  this  Paragraph  8;  and  (III)  inheritance,  gift,  transfer,  franchise  or  estate  taxes.    Landlord  may  contest  by
appropriate legal proceedings the amount, validity, or application of any Taxes or liens thereof and any costs incurred in such contest may be included as part
of Taxes (but not to exceed the amount of savings reasonably expected to be achieved by Landlord).  If any such tax or excise is levied or assessed directly
against Tenant, then Tenant shall be responsible for and shall pay the same at such times and in such manner as the taxing authority shall require.  Tenant shall
be liable for, and pay on or before the date due, all taxes levied or assessed against any personal property or fixtures placed in the Premises, whether levied or
assessed  against  Landlord  or  Tenant,  and  if  any  such  taxes  are  levied  or  assessed  against  Landlord  or  Landlord's  property  and  (a)  Landlord  pays  them  or
(b) the assessed value of Landlord's property is increased thereby and Landlord pays the increased taxes, then Tenant shall pay to Landlord such taxes within
ten (10) days after Landlord's request therefor. At Tenant's request, and provided that it is then deemed advisable by Landlord in the exercise of Landlord's
reasonable business judgment, Landlord shall bring or cause to be brought an application or proceeding for reduction of the assessed valuation of the Building
or parcel on which the Premises is situated, as applicable, in order to reduce Taxes.  All costs and expenses arising from any such contest shall be paid for by
Tenant.  In the event that Taxes are increased as a result of any such contest, then Tenant shall be responsible for its Proportionate Share of such increase in
Taxes during the Lease Term.  Notwithstanding the foregoing, Landlord shall have no obligation to contest any Taxes, if, in the reasonable business judgment
of Landlord, any such contest could adversely impact the Premises and/or the Project.  To the extent that Landlord is actually granted a reduction in Taxes,
then  Tenant  shall  receive  its  Proportionate  Share  of  the  benefit  of  any  actual  reduction  in  Taxes  that  are  payable  by  Tenant  hereunder,  less  any  costs  and
expenses incurred by Landlord in obtaining such reduction.

existence and amount of each insurance policy required hereunder shall be delivered to Landlord prior to delivery or possession of the Premises and ten (10)
days following each renewal date.  Certificates of insurance shall evidence that Landlord, its trustees, officers, directors, members, agents, and employees,

additional  coverage  requirements  must  be  commercially  reasonable  based  on  the  insurance  requirements  of  other  institutional  owners  of  commercial
properties similar to the Project in the market in which the Project is located.

(v)

(vi)

Should  Tenant  engage  the  services  of  any  contractor  to  perform  work  or  construct  any  Tenant-Made

engaged by contractor.

(b)

Landlord's Insurance.  Landlord shall obtain and maintain the following: (1) special form/cause of loss (formerly all-risk)
property insurance covering damage to the Building constructed or installed by Landlord (excluding foundations), in an amount equal to the full replacement
cost thereof, less a commercially reasonable deductible if Landlord so chooses; provided, however, Landlord shall not be obligated to insure any furniture,
equipment,  trade  fixtures,  machinery,  goods,  or  supplies  which  Tenant  may  keep  or  maintain  in  the  Premises  or  any  alteration,  addition,  or  improvement
which Tenant may make upon the Premises; and (2) commercial general liability insurance, which shall be in such amount as Landlord so determines (in
Landlord's commercially reasonable discretion) and shall be in addition to, and not in lieu of, any insurance required to be maintained by Tenant. Tenant shall
not  be  included  as  an  additional  insured  on  any  policy  of  liability  insurance  maintained  by  Landlord.    In  addition,  Landlord  may,  but  is  not  obligated  to,
maintain such other insurance and additional coverages as it may deem necessary, including, but not limited to, flood insurance, earthquake insurance, rent
loss insurance and pollution legal liability insurance.  The premiums for all such insurance shall be included as part of the Operating Expenses charged to
Tenant pursuant to Paragraph 6 hereof.  The Project or Building may be included in a blanket policy (in which case the cost of such insurance allocable to the
Project  or  Building  will  be  determined  by  Landlord  based  upon  the  insurer's  cost  calculations).    Tenant  shall  also  reimburse  Landlord  for  any  increased
premiums  or  additional  insurance  that  Landlord  reasonably  deems  necessary  as  a  result  of  Tenant's  use  of  the  Premises.    Tenant  shall  not  be  named  as  an
additional insured on any policy of liability insurance maintained by Landlord.

(c)

Waiver of Subrogation.  Both parties agree to waive and cause its insurance carriers to waive all rights of subrogation by
the  insurers  and  all  rights  based  upon  an  assignment  from  its  insured,  against  Landlord  or  Tenant,  their  officers,  directors,  employees,  managers,  agents,
invitees  and  contractors,  in  connection  with  any  loss  or  damage  thereby  insured  against.    The  failure  of  a  party  to  insure  its  property  shall  not  void  this
waiver.  Landlord shall not be liable for any damage or injury to the person, business (or any loss of income therefrom), goods, wares, merchandise or other
property of Tenant, Tenant's agents, employees, licensees, invitees, or any other party in or about the Premises, whether such damage or injury is caused by or
results  from:  (i)  fire,  steam,  electricity,  water,  gas  or  rain;  (ii)  the  breakage,  leakage,  obstruction  or  other  defects  of  pipes,  sprinklers,  wires,  appliances,
plumbing, air conditioning or lighting fixtures or any other cause; (iii) conditions arising in or about the Premises or upon other portions of the Project, or
from other sources or places; or (iv) any act or omission of any other tenant of the Project. Landlord shall not be liable for any such damage or injury even
though the cause of or the means of repairing such damage or injury are not accessible to Tenant. Notwithstanding anything to the contrary contained in this
Lease, each party hereby waives and releases any claims against the other, and its officers, directors, employees, managers, agents, invitees and contractors
for any loss or damage to any of the Premises, the Building and the Project, and to any personal property regardless of negligence or fault; however, such
waiver shall not apply to any deductible amounts maintained by a party under its insurance.  The waivers set forth in this Paragraph 9(c) shall be in addition
to, and not in substitution for, any other waivers, indemnities, or exclusions of liabilities set forth in this Lease.  

10.

Landlord's Repairs.  Subject to Paragraphs 15 and 16  of  this  Lease  and  excluding  any  damages  caused  by  Tenant  or  any  Tenant
Party, Landlord shall, at Landlord's sole cost (and not included in Operating Expenses), except as otherwise set forth in this Lease, maintain in good condition
and repair the structural elements of: (a) the roof of the Building (not including the roof membrane, which shall be maintained and repaired by Landlord as
part of Operating Expenses), (b) the exterior walls of the Building (not including painting and caulking, which shall be maintained by Landlord as part of
Operating Expenses), and (c) the foundations for the Building (collectively, the "Building Structural Elements"), including repairs to the Building Structural
Elements necessitated by subgrade movement.  Additionally, subject to Paragraphs 15 and 16 of this Lease, Landlord shall maintain and repair and keep the
same in a good condition and repair (reasonable wear and tear excluded and damages caused by Tenant or any Tenant Party excluded), as part of Operating
Expenses (subject to the terms of this Lease, including the amortization of capital improvements and the exclusions to Operating Expenses as described in
Paragraph 6(c) above), (I) the non-

1111154v7

structural  elements  of  the  roof  (including  the  roof  membrane),  and  (II)  the  Common  Areas;  utilities  systems  (including  the  electrical  system)  serving  the
Building  up  to  the  point  of  connection  with  the Building;  any  Building  systems  to  the  extent  such  systems  are  installed  by  Landlord  and  not  exclusively
serving the Premises; the fire pump(s) serving the Project; the non-structural elements of the roof (including the roof membrane); the non-structural elements
of  the  exterior  walls  (it  being  agreed  that  any  costs  incurred  by  Landlord  to  paint  the  exterior  of  the  Building  shall  passed  through  to  Tenant  as  part  of
Operating Expenses in accordance with Paragraph 6 above); the non-structural elements of the foundations; and the exterior areas of the Project, including,
but not limited to, the parking areas and driveways of the Premises and the landscaping and grounds surrounding the Building and Project (including, without
limitation, mowing thereof and snow removal thereon).  The term "walls" as used in this Paragraph 10 shall not include windows, glass or plate glass, doors
or  overhead  doors,  special  store  fronts,  dock  bumpers,  dock  plates  or  levelers,  or  office  entries,  all  of  which  shall  be  maintained  by  Tenant.   Tenant  shall
promptly  give  Landlord  written  notice  of  any  repair  required  by  Landlord  pursuant  to  this  Paragraph  10,  after  which  Landlord  shall  have  a  reasonable
opportunity to repair such item. Tenant hereby waives the benefit of California Civil Code Sections 1941 and 1942, and any other statute providing a right to
make repairs and deduct the cost thereof from the rent or to terminate this Lease due to Landlord's failure to keep the Premises in good order, condition and
repair.

11.

Tenant's Repairs.

(a)

Subject to Paragraphs 15 and 16 of this Lease, Landlord's obligations expressly set forth in Paragraph 10 and Landlord's
Construction Warranty (as defined in Exhibit B attached hereto), Tenant, at its sole expense, shall repair, replace and maintain in good order, condition and
repair (reasonable wear and tear, damage caused by Landlord or its agents, employees, contractors, subcontractors, representatives, consultants, licensees or
invitees [collectively, "Landlord Parties"] excepted) and in compliance with all Legal Requirements and Private Restrictions all portions of the Premises,
and all other areas, improvements and systems exclusively serving the Premises including, without limitation, docks, dock equipment and loading areas, truck
doors, plumbing, water, sewer lines, from the points of connection with the Building, fire sprinklers and fire protection systems within the Premises from
points of connection with the Building, entries, doors, door frames, ceilings, windows, window frames, interior walls, and the interior side of demising walls
(if any), and heating, ventilation and air conditioning ("HVAC") systems, and other building and mechanical systems serving the Premises.  Such repair and
replacements include capital expenditures and repairs whose benefit may extend beyond the Lease Term.  If, during the last two (2) years of the Lease Term, a
capital  replacement  of  an  HVAC  unit  is  required  (each  of  the  foregoing,  an  "Capital  HVAC  Item"  and  collectively  "Capital  HVAC  Items"),  then,  (A)
provided no Event of Default exists under this Lease, (B) Tenant has maintained the maintenance service contract(s) for the HVAC systems pursuant to (i)
below, and (C) provided further that such Capital HVAC Items: (I) will have a useful life in excess of the remaining portion of the then applicable Lease
Term,  and/or  (II)  were  not  necessitated  by  Tenant's  failure  to  properly  maintain  such  systems  in  accordance  with  the  manufacturer's  recommendations,  or
Tenant's breach of this Lease or the negligent act or omission of Tenant or any of the Tenant Parties (in which case Tenant shall be responsible therefor at
Tenant's sole cost and expense), then Landlord shall purchase and perform such Capital HVAC Item(s) and the cost thereof shall be amortized on a straight
line basis (with interest) over the useful life thereof, and Tenant shall pay such amortized payments to Landlord on the first day of each month together with
its Base Rent payments (but without regard to any credit or abatement of Base Rent) through and including the expiration of the Lease Term (as the same may
be extended).  Notwithstanding anything to the contrary contained herein, Landlord may elect not to complete the Capital HVAC Item(s) (unless such Capital
HVAC Item(s) are normal and customary HVAC units serving the northern office portion of the Premises, which normal and customary HVAC units Landlord
shall not be permitted to object to replacing provided the other terms and conditions contained in this Paragraph 11(a) are satisfied) upon written notice to
Tenant (which notice shall be given no later than ten (10) business days after receipt of Tenant's written notice of a Capital HVAC Item) in which case (1)
Landlord shall not be obligated to complete the applicable Capital HVAC Item, (2) notwithstanding anything to the contrary contained in this Lease, Tenant
shall  have  the  right,  but  not  the  obligation,  to  replace  the  applicable  Capital  HVAC  Item  at  its  sole  cost  and  expense;  and  (3)  if  Tenant  does  not  elect  to
complete such replacement pursuant to clause (2), above, then, as Landlord's sole and exclusive remedy, Tenant shall be required to remove any such HVAC
units  on  or  before  the  expiration  of  the  Lease  Term.  Within  ten  (10)  days  of  the  Commencement  Date,  Tenant,  at  Tenant's  expense,  shall  enter  into
maintenance service contracts for (i) the maintenance and repair of the heating, ventilation and air conditioning systems and other mechanical and building
systems serving the Premises, and (ii) Tenant's trash collection, sweeping and removal; provided, however, in the event that Tenant fails to enter into such
service  contracts  and/or  to  properly  maintain  and/or  perform  the  foregoing  in  accordance  with  the  terms  and  conditions  contained  in  this  Lease,  then  at
Landlord's written election (but at Tenant's expense) after written notice to Tenant and

1111154v7

20

 
 
 
 
Tenant's failure to cure the same within fifteen (15) days after Tenant's receipt of such written notice, Landlord shall have the right (but not the obligation) to
enter into such maintenance service contracts.  Landlord may request a list of vendors providing services under the aforementioned maintenance contractors
together with the scope of such services and if Landlord provides Tenant with written notice that it reasonably objects to any of the listed vendors, then Tenant
shall replace such vendor within a reasonable period of time.  Without limiting any of the foregoing, Tenant, at Tenant's sole cost and expense, shall store all
trash and other solid waste within the Premises or in such areas as may be reasonably designated by Landlord for such storage.  Tenant shall not burn any
trash or garbage at any time in or about the Premises and/or the Project.

In the event that any repair or maintenance obligation required to be performed by Tenant hereunder is likely to adversely
affect the Building Structural Elements, then Tenant shall use contractors that are approved in advance by Landlord for such work (which approval shall not
be unreasonably withheld, conditioned or delayed).

(b)

(c)

Within the fifteen (15) day period prior to the expiration or termination of this Lease, Tenant shall deliver to Landlord a
certificate from an engineer reasonably acceptable to Landlord certifying that the hot water equipment, dock equipment, and the HVAC system are then in
good  repair  and  working  order.    If  Tenant  fails  to  perform  any  repair  or  replacement  for  which  it  is  responsible  (or  if  Tenant  fails  to  obtain  any  of  the
certifications described in the immediately preceding sentence), Landlord may perform such work (and/or obtain such certifications) and be reimbursed by
Tenant within ten (10) days after demand for all costs and expenses incurred by Landlord in connection therewith.  Subject to Paragraphs 9 and 15, Tenant
shall bear the full cost of any repair or replacement to any part of the Building or Project that results from any breach by Tenant of the terms and conditions of
this Lease or by any negligent act or omission of Tenant or any Tenant Party.

12.

Tenant-Made Alterations and Trade Fixtures.

(a)

Subject  to  the  terms  set  forth  below,  any  alterations,  additions,  or  improvements  (including,  without  limitation,
alterations,  additions  or  improvements  to  the  roof  of  the  Building,  but  excluding  the  Landlord  Work  to  be  constructed  by  Landlord,  the  initial  Tenant
Improvements and/or any Tenant Change(s) to be constructed pursuant to Exhibit B attached hereto, which shall not constitute Tenant-Made Alterations and
shall be governed by the terms of the Work Letter attached hereto as Exhibit B and not the terms of this Paragraph 12(a)) made by or on behalf of Tenant to
the Premises ("Tenant-Made Alterations") shall be subject to compliance with Legal Requirements and Private Restrictions (including, without limitation,
approval  of  any  applicable  design  review  committee[s]  or  owners  association[s])  and  Landlord's  prior  written  consent,  which  consent  shall  not  be
unreasonably  withheld,  conditioned  or  delayed  (except  to  the  extent  that  the  subject  Tenant-Made  Alterations  could  reasonably  be  expected  to  adversely
impact the structure and/or structural elements of a Building, or any Building systems, in which event Landlord's consent shall be in its sole and absolute
discretion,  or  the  exterior  appearance  of  the  Project,  Building,  and/or  Premises,  in  which  event  Landlord's  consent  shall  be  in  its  sole  and  good  faith
discretion).    Tenant  acknowledges  that,  subject  to  the  terms  of  Paragraph  43  below,  Landlord  does  not  have  control  over  any  applicable  design  review
committee(s)  and/or  owners  association(s)  and  their  review  of  any  proposed  Tenant-Made  Alterations.    Therefore,  such  design  review  committee(s)  and
owners association(s) may grant or withhold its/their consent in accordance with applicable Legal Requirements and/or Private Restrictions, which may or
may not require such design review committee(s) and/or owners association(s) to act reasonably in granting or withholding its/their consent.  Notwithstanding
the  foregoing,  but  subject  to  compliance  with  Legal  Requirements  and  Private  Restrictions,  Landlord's  consent  shall  not  be  required  for  non-structural
alterations  to  the  interior  of  the  Premises  (that  are  not  visible  from  the  exterior  of  the  Premises)  costing  less  than  Two  Hundred  Fifty  Thousand  Dollars
($250,000.00) in the aggregate in any consecutive twelve (12) month period, provided that in any such case, the alterations (i) do not affect the structure of
the Building, or adversely affect any Building systems (including, without limitation, electrical, plumbing, life safety, and/or HVAC systems), or the exterior
appearance  of  the  Project,  Building  or  the  Premises,  (ii)  do  not  require  an  approval  under  any  Private  Restrictions,  and  (iii)  do  not  involve  Building
penetrations  (collectively,  "Permitted Alterations").  Tenant  shall  give  Landlord  at  least  ten  (10)  days  prior  written  notice  of  such  Permitted  Alterations
("Permitted  Alterations  Notice"),  which  Permitted  Alterations  Notice  shall  be  accompanied  by  reasonably  adequate  evidence  that  such  Permitted
Alterations meet the criteria contained in this Paragraph 12.  Permitted Alterations shall be deemed to constitute Tenant-Made Alterations for all purposes
under  this  Lease  (except  that  Landlord's  consent  shall  not  be  required  so  long  as  the  foregoing  provisions  have  been  satisfied).   Tenant  shall  cause,  at  its
expense, all Tenant-Made Alterations, including without limitation Permitted Alterations, to comply with insurance requirements, with Legal Requirements
and  Private  Restrictions,  and  shall  construct  at  its  expense  any  alteration  or  modification  required  by  Legal  Requirements  and/or  Private  Restrictions  as  a
result of any Tenant-Made Alterations and/or Permitted Alterations.  

1111154v7

21

 
 
 
 
(b)

All  Tenant-Made  Alterations  and  Permitted  Alterations  shall  be  constructed  in  a  good  and  workmanlike  manner,  in
compliance with Legal Requirements and the Private Restrictions, and by contractors reasonably acceptable to Landlord and only good grades of materials
shall  be  used.    All  plans  and  specifications  for  any  Tenant-Made  Alterations  (other  than  Permitted  Alterations,  unless  otherwise  required  by  Legal
Requirements or Private Restrictions) shall be submitted to (i) Landlord for its approval, which approval shall not be unreasonably withheld, conditioned or
delayed  (except  to  the  extent  that  the  subject  Tenant-Made  Alterations  could  reasonably  be  expected  to  adversely  impact  the  structure  and/or  structural
elements of the Building, the exterior appearance of the Project, Building, and/or Premises or any Building systems, in which event Landlord's consent shall
be in its sole and absolute discretion), and (ii) any applicable design review committee(s) and/or owners association(s) for their respective approvals (which
approvals may be granted or withheld in accordance with the applicable Legal Requirements and Private Restrictions).   Tenant shall reimburse Landlord for
its reasonable out-of-pocket costs in reviewing plans and specifications and Tenant agrees that Landlord has the right to condition Landlord's approval of any
Tenant-Made Alterations that affect any Building Structural Elements upon charging a commercially reasonable construction monitoring fee (not to exceed
two percent (2%) of the total cost of such Tenant-Made Alterations). Landlord's right to review plans and specifications and/or to monitor construction shall
be  solely  for  its  own  benefit,  and  Landlord  shall  have  no  duty  to  see  that  such  plans  and  specifications  or  construction  comply  with  Legal  Requirements
and/or Private Restrictions or are otherwise performed to any particular standard or in any particular manner.  

(c)

Tenant  shall  provide  Landlord  with  the  identities  and  mailing  addresses  of  all  persons  performing  work  or  supplying
materials, prior to beginning such work, and Landlord may post on and about the Premises notices of non-responsibility pursuant to applicable law. Tenant
shall furnish security or make other arrangements satisfactory to Landlord to assure payment for the completion of all work free and clear of liens and shall
provide  certificates  of  insurance  for  worker's  compensation  and  other  coverage  in  amounts  and  from  an  insurance  company  satisfactory  to  Landlord
protecting Landlord against liability for personal injury or property damage during construction.  Upon completion of any Tenant-Made Alterations, Tenant
shall deliver to Landlord final, unconditional lien waivers in statutory form from all such contractors and subcontractors.  

(d)

Upon  surrender  of  the  Premises,  all  Tenant-Made  Alterations,  Permitted  Alterations,  and  any  leasehold  improvements
constructed by Landlord or Tenant (including, without limitation, the Tenant Improvements and/or any Tenant Change, but expressly excluding all of Tenant's
trade fixtures, inventory, furnishings, equipment and other personal property at the Premises [all of which may be removed by Tenant from time to time and at
any time during the Lease Term]) shall remain on the Premises as Landlord's property, except to the extent Landlord requires removal at Tenant's expense of
any such items or Landlord and Tenant have otherwise agreed in writing in connection with Landlord's consent to any Tenant Improvements (in accordance
with Exhibit B), Tenant Change (in accordance with Exhibit B), and/or Tenant-Made Alterations (or following receipt of a Permitted Alterations Notice or a
Permitted Alterations List, as applicable).  Notwithstanding the foregoing, Tenant shall have the right, at the time it requests Landlord's consent and delivers
all plans and specifications to any Tenant-Made Alteration (or, with respect to Permitted Alterations, at the time it delivers a Permitted Alterations Notice or
Permitted Alterations List, as applicable, or with respect to the Tenant Improvements and/or a Tenant Change, in accordance with the terms and condition
contained  in  Exhibit B),  to  make  a  written  request  that  Landlord  notify  Tenant  whether  Tenant  shall  be  required  to  remove  the  applicable  Tenant-Made
Alteration, Tenant Improvement, Tenant Change and/or Permitted Alteration at the expiration or termination of the Lease Term, in which event Tenant shall
only  be  obligated  to  remove  (i)  those  Tenant-Made  Alterations,  Tenant  Improvements,  Tenant  Changes  and  Permitted  Alterations  that  Landlord  notified
Tenant in writing at the time Landlord provides its consent that it must remove at the end of the Lease Term, and (ii) those Tenant-Made Alterations, Tenant
Improvements, Tenant Changes and Permitted Alterations that Tenant did not timely seek or did not obtain Landlord's written consent to leave in place at the
end of the Lease Term, and that Landlord ultimately requires Tenant to remove.  Failure of Landlord to notify Tenant in writing at the time that Landlord
issues  its  consent  that  a  Tenant-Made  Alteration,  Tenant  Improvement,  and/or  any  Tenant  Change  must  be  removed  (or  within  ten  (10)  business  days
following  Landlord's  receipt  of  a  Permitted  Alterations  Notice  or  Permitted  Alterations  List,  as  applicable)  shall  mean  that  Tenant  shall  be  obligated  to
remove the Tenant-Made Alteration, Tenant Improvement, Tenant Change and/or Permitted Alteration (as applicable) at the expiration or earlier termination
of this Lease.  Notwithstanding the foregoing or anything to the contrary contained herein, Landlord hereby agrees that Tenant shall not be required to remove
(I) the Tenant Improvements located in the northern office area of the Premises as depicted on the site plan attached hereto as Exhibit F, (II) conventional and
customary building systems (e.g. mechanical, electrical, plumbing and life safety systems) typically installed in office/industrial/warehouse buildings in the
market area (but specifically excluding any specialty systems and equipment, including, without limitation, any manufacturing and/or lab equipment, which
Tenant shall be required to

1111154v7

22

 
 
 
 
remove), and (III) basic structural upgrades to the Building (collectively, the “Improvements Not Subject to Restoration”). Notwithstanding the foregoing
to  the  contrary,  Tenant  shall  be  required  to  remove  (and  repair  any  damage  caused  by  such  removal)  any  and  all  mezzanines  (excluding  the  mezzanine
installed by Landlord as part of the Landlord Work) from the Premises (including, without limitation, any equipment and/or building systems placed and/or
installed on such mezzanines, whether or not the same are depicted in Exhibit F and whether or not the same are conventional and/or customarily installed in
office/industrial/warehouse  buildings  in  the  market  area). Any Tenant-Made Alterations, Tenant  Improvements,  Tenant  Changes  and  Permitted  Alterations
which Landlord has elected to not require Tenant to remove shall remain on the Premises as Landlord's property and shall be deemed abandoned by Tenant at
the expiration or earlier termination of the Lease.  Prior to the expiration or termination of this Lease, Tenant, at its sole expense, shall repair any and all
damage caused by the removal of any Tenant-Made Alterations, Tenant Improvements, Tenant Changes and/or Permitted Alterations.  

(e)

Tenant, at its own cost and expense and without Landlord's prior approval, may erect such shelves, bins, machinery, racks
and  trade  fixtures  (collectively  "Trade  Fixtures")  in  the  ordinary  course  of  its  business  provided  that  such  items  do  not  adversely  impact  the  Building
Structural Elements, do not overload the Premises (i.e. the weight and/or size of such items do not exceed the specifications and thresholds thereof) and the
construction, erection, and installation thereof complies with all Legal Requirements and Private Restrictions and with any other applicable requirements set
forth in this Paragraph 12 above.  Prior to the expiration or termination of this Lease, Tenant, at its sole expense, shall remove its Trade Fixtures and shall
repair any and all damage to the Project, Building and/or Premises caused by such removal.

13.

Signs.  Subject to compliance with all Legal Requirements, Private Restrictions, any sign criteria adopted by the Pacific Research
Center, any sign criteria adopted by Landlord for the Project, the City of Newark signage requirements, and receipt of prior written approval from Landlord,
and  any  applicable  design  review  committee(s)  and/or  owners  association(s)  as  to  size,  quantity,  design,  location,  graphics,  materials,  colors  and  similar
specifications (which approval with respect to Landlord shall not be unreasonably withheld, conditioned or delayed, but with respect to any applicable design
review committee(s) and/or owners association(s) may be granted or withheld in accordance with Legal Requirements and/or Private Restrictions), Tenant
shall have the right (at Tenant's sole cost and expense) to place, maintain, alter, modify and repair graphics and signage (in reasonable dimensions as approved
by  Landlord)  depicting  Tenant's  trade  name  and  logo  mutually  approved  locations  on  the  exterior  of  the  Building  ("Tenant's  Exterior  Signage").
Notwithstanding  the  foregoing,  Landlord  hereby  approves  of  Tenant's  trade  name  (i.e.,  "Allogene")  and  Tenant's  logo,  as  depicted  on  Exhibit D  attached
hereto, but all of the foregoing shall still remain subject to compliance with all Legal Requirements, Private Restrictions, any sign criteria adopted by the
Pacific Research Center, the City of Newark signage requirements, and any applicable design review committee(s) and/or owners association(s). Any and all
costs in connection with Tenant's Exterior Signage, including without limitation the permitting, fabrication, installation, maintenance and removal of Tenant's
Exterior Signage (including the cost of removal of Tenant's Exterior Signage and repair to the Building and Premises caused by such removal) shall be borne
by Tenant.  Tenant (at Tenant's sole cost and expense) agrees to maintain and repair (in good first-class condition at all times), and replace (as necessary),
Tenant's Exterior Signage. Upon surrender or vacation of the Premises at the expiration or earlier termination of the Lease Term, Tenant shall, at its sole cost,
remove all of Tenant's Exterior Signage and repair, paint, and/or replace the Building fascia surface to which its signs are attached.  Tenant shall, at its sole
cost, obtain all applicable governmental permits and approvals for sign and exterior treatments; provided, however, that Landlord shall reasonably cooperate
with Tenant's efforts (at no out-of-pocket cost to Landlord) to obtain such permits and approvals.  Notwithstanding the foregoing, other than the current name
of Tenant (i.e. "Allogene Therapeutics, Inc.") in no event shall any Objectionable Name be placed on Tenant's Exterior Signage.  As used herein, the term
"Objectionable Name" shall mean any name which relates to an entity which is of a character or reputation, or is associated with a political orientation or
faction, which (1) is inconsistent with the quality of the Building as a first-class institutional quality building; or (2) would adversely impact the value of the
Project, Building or Premises (in Landlord's good faith discretion); or (3) are generally perceived in the public to be disreputable.  Further notwithstanding
anything  to  the  contrary  contained  herein,  Landlord  hereby  discloses  to  Tenant  (and  Tenant  hereby  acknowledges)  that  signage  on  or  about  the  Building,
Premises and/or Project may not be permitted by Legal Requirements and/or the Private Restrictions.  Landlord makes no representation and/or warranty as to
whether Tenant will be permitted to place signage on or about the Premises, Building, and/or Project.  In the event Tenant receives approval from Landlord,
and any applicable design review committee(s) and/or owners association(s) as to Tenant's signage and any such approval is later withdrawn through no bad
faith act or willful misconduct of Landlord, Tenant agrees that Landlord shall not be liable therefor and that such existence or nonexistence of Tenant's right to
use signage on or about the Premises, Building, and/or Project shall not affect this Lease and/or any of Tenant's other obligations

1111154v7

23

 
 
 
 
under this Lease.  Landlord shall have no right to place any signage on the Premises without Tenant's prior written consent (which consent may be  withheld
in  Tenant’s  sole  discretion);  provided,  however,  that  the  foregoing  restriction  shall  not  apply  to  (and  Landlord  may  place  on  the  Premises)  (i)  any  signs
required to comply with Legal Requirements and/or Private Restrictions, (ii) directional signage and/or building identification signage (as may be required by
any association with jurisdiction over the Project), and (iii) one sign on the Building (so long as the same is in a location reasonably acceptable to Tenant that
does not otherwise obstruct or block Tenant's signage) stating the Premises are available for sale or, during the last nine (9) months of the Lease Term, that the
Premises are available for let (as long as Tenant has not exercised any remaining "Option" (as defined in Paragraph 41 below).

14.

Parking.    Tenant  shall  be  entitled  to  park  up  to  one  hundred  fifty-six  (156)  customary  passenger  vehicles  in  common  with  other
tenants in those areas designated by Landlord for non-reserved parking, on a first come, first served basis, provided, however, 12 of such 156 parking spaces
as identified on Exhibit E hereto (the “Tenant’s Exclusive Parking Area”) shall be for Tenant’s exclusive use, subject in all cases (with respect to the entire
allotment of Tenant's parking spaces) to Tenant's obligation to comply with all Legal Requirements and Private Restrictions, the terms of this Lease and all
commercially reasonable and non-discriminatory rules and regulations which are prescribed from time to time by Landlord. In addition, Tenant shall have the
right, at Tenant's sole cost and expense, to create and utilize up to an additional twenty-three (23) non-exclusive parking spaces by striping the dock area
serving  the  Premises,  subject  to  Landlord's  review  and  approval  of  plans  and  specifications  for  same,  and  Tenant's  obligation  to  comply  with  all  Legal
Requirements  and  Private  Restrictions,  the  terms  of  this  Lease  and  all  commercially  reasonable  and  non-discriminatory  rules  and  regulations  which  are
prescribed from time to time by Landlord. Subject to compliance with Legal Requirements and Private Restrictions, Tenant shall have the right to implement
and utilize, at Tenant's sole cost and expense, valet parking, but only if Tenant is not in any manner impeding or interfering with any of the drive aisles or
other areas of the Project. Tenant  acknowledges  that  Landlord  has  no  obligation  to  police  the  usage  of  Tenant's  parking  spaces  and  Landlord  shall  not  be
responsible for enforcing Tenant's parking rights against any third parties.  All motor vehicles (including all contents thereof) shall be parked in the Project
parking areas at the sole risk of Tenant, it being expressly agreed and understood Landlord has no duty to insure any of said motor vehicles (including the
contents  thereof),  and  Landlord  is  not  responsible  for  the  protection  and  security  of  such  vehicles.  NOTWITHSTANDING  ANYTHING  TO  THE
CONTRARY  CONTAINED  IN  THIS  LEASE,  LANDLORD  SHALL  HAVE  NO  LIABILITY  WHATSOEVER  FOR  ANY  PROPERTY  DAMAGE  OR
LOSS  WHICH  MIGHT  OCCUR  ON  THE  PARKING  AREAS  OR  AS  A  RESULT  OF  OR  IN  CONNECTION  WITH  THE  PARKING  OF  MOTOR
VEHICLES IN ANY OF THE PARKING SPACES.  

15.

Restoration.

(a)

If  at  any  time  during  the  Lease  Term  the  Premises  are  materially  damaged  by  a  fire  or  other  casualty,  Landlord  shall
notify Tenant within sixty (60) days after such damage as to the amount of time Landlord reasonably estimates it will take to restore the Premises.  If the
restoration time is estimated to exceed three hundred sixty (360) days from the date the parties receive notice of such damage, either Landlord or Tenant may
elect to terminate this Lease upon notice to the other party given no later than thirty (30) days after Landlord's notice.  If neither party elects to terminate this
Lease or if Landlord estimates that restoration will take three hundred sixty (360) days or less, or if the casualty damage in question is not material, then
Landlord shall promptly and diligently restore the Premises excluding the Tenant-Made Alterations, the Tenant Improvements and/or any other improvements
installed by Tenant or by Landlord and paid by Tenant, subject to delays arising from the collection of insurance proceeds, any Tenant Delay(s) and/or from
Force Majeure events.  Tenant at Tenant's expense shall promptly perform, subject to delays arising from the collection of insurance proceeds, or from Force
Majeure  events,  all  repairs  or  restoration  not  required  to  be  done  by  Landlord  and  shall  promptly  re-enter  the  Premises  and  commence  doing  business  in
accordance with this Lease.  Base Rent and Tenant's Proportionate Share of Operating Expenses shall be abated for the period of repair and restoration in the
proportion which the area of the Premises, if any, which is not usable by Tenant bears to the total area of the Premises. Notwithstanding the foregoing, either
party may terminate this Lease upon thirty (30) days written notice to the other if the Premises are substantially damaged during the last year of the Lease
Term and Landlord reasonably estimates that it will take more than thirty (30) days to repair such damage.  Notwithstanding the foregoing, if Tenant was
entitled to but elected not to exercise its right to terminate the Lease and Landlord does not substantially complete the repair and restoration of the Premises
within sixty (60) days after the expiration of the estimated period of time set forth in the Landlord's estimate (except to the extent that substantial completion
is delayed as a result of events of Force Majeure or any acts or omission of Tenant or any Tenant Party), then Tenant may terminate this Lease by written
notice  to  Landlord  within  ten  (10)  days  after  the  expiration  of  such  period  (but  prior  to  substantial  completion  of  the  restoration),  as  the  same  may  be
extended.

1111154v7

24

 
 
 
 
(b)

If the Premises are destroyed or substantially damaged by any peril not covered by the insurance maintained (or required
to be maintained) by Landlord under this Lease (and the total out-of-pocket cost to Landlord shall exceed five percent (5%) of the replacement cost of the
Building),  or  any  Landlord's  mortgagee  requires  that  insurance  proceeds  be  applied  to  the  indebtedness  secured  by  its  mortgage  following  Landlord's
reasonable and good faith efforts to cause the proceeds to be applied towards restoration of the Premises (to the extent permitted under the applicable loan
agreements,  and  to  the  extent  Landlord  reasonably  determines  that  restoration  is  economically  viable),  Landlord  may  terminate  this  Lease  by  delivering
written notice of termination to Tenant within thirty (30) days after such destruction or damage or such requirement is made known by any such Landlord's
mortgagee, as applicable, whereupon all rights and obligations hereunder shall cease and terminate, except for any liabilities of Tenant which accrued prior to
Lease termination; provided,  however,  such  termination  shall  be  null  and  void  if  Tenant  agrees  in  writing  to  pay  all  uninsured  amounts  and  all  amounts
required by Landlord's mortgagee (in each case in excess of five percent (5%) of the replacement cost of the Building), and delivers written notice of such
election, together with all required funds, within ten (10) business days following Landlord's notice of termination.   If Landlord elects to repair or restore
such damage or destruction (or a termination election by Landlord is rendered void because Tenant has elected to pay the additional amounts described above
and delivered such amounts to Landlord), this Lease shall continue in full force and effect, but Base Rent shall be proportionately reduced as provided in
Paragraph 15(a).  If Landlord elects to terminate this Lease (and such termination is not rendered void as described above), such termination shall be effective
as of the date of the occurrence of such damage or destruction.  

(c)

Notwithstanding the foregoing (but subject to Paragraph 9(c)), to the extent the Building and/or the Premises are wholly
or partially damaged or destroyed as a result of the negligence or willful misconduct of Tenant and such risk is not covered by Landlord's insurance coverage
or the coverage required to be maintained by Landlord herein, then Tenant shall have no right to terminate this Lease as a result of the casualty damage and
Tenant shall forthwith diligently undertake to repair or restore all such damage or destruction at Tenant's sole cost and expense, or Landlord may at its option
undertake such repair or restoration at Tenant's sole cost and expense; provided, however, that Tenant shall be relieved of its repair and payment obligations
pursuant to this Paragraph 15(c) to the extent that insurance proceeds are collected by Landlord to repair such damage (or, in the event that Landlord has
failed to maintain the property insurance required to be maintained by Landlord hereunder, to the extent that insurance proceeds would have been collected
had Landlord maintained such required insurance), although Tenant shall in such events pay to Landlord the full amount of the deductible under Landlord's
insurance policy and any amounts not insured.  This Lease shall continue in full force and effect without any right of Tenant to terminate the Lease, nor any
abatement or reduction in Base Rent or Operating Expenses or other payments owed by Tenant; provided, however, that Base Rent shall be abated to the
extent of any rental loss insurance proceeds received by Landlord.

(d)

The  provisions  of  this  Paragraph  15  shall  constitute  Tenant's  sole  and  exclusive  remedy  in  the  event  of  damage  or
destruction  to  the  Premises  or  Project,  and  Tenant  waives  and  releases  all  statutory  rights  and  remedies  in  favor  of  Tenant  in  the  event  of  damage  or
destruction, including without limitation those available under California Civil Code Sections 1932 and 1933(4).  No damages, compensation or claim shall
be payable by Landlord for any inconvenience, any interruption or cessation of Tenant's business, or any annoyance, arising from any damage or destruction
of all or any portion of the Premises or Project.

16.

Condemnation.  If any part of the Premises or the Project should be taken for any public or quasi-public use under governmental
law, ordinance, or regulation, or by right of eminent domain, or by private purchase in lieu thereof (a "Taking" or "Taken"), and (a) the Taking would prevent
or  materially  interfere  with  Tenant's  use  of  the  Premises  (as  determined  by  Tenant's  in  Tenant's  commercially  reasonable  judgment),  (b)  in  Landlord's
commercially  reasonably  judgment  would  materially  interfere  with  or  impair  its  ownership  or  operation  of  the  Project,  or  (c)  as  a  result  of  such  Taking,
Landlord's  mortgagee  accelerates  the  payment  of  any  indebtedness  securing  all  or  a  portion  of  the  Project,  then  upon  written  notice  by  Landlord  (in
connection with item (b) or (c) above), or Tenant (in connection with item (a) above), this Lease shall terminate and Base Rent shall be apportioned as of said
date.  If part of the Premises shall be Taken, and this Lease is not terminated as provided above, the Base Rent payable hereunder during the unexpired Lease
Term shall be reduced to such extent as may be fair and reasonable under the circumstances, and Landlord shall restore the Premises as near as reasonably
attainable  to  its  condition  prior  to  the  Taking;  provided,  however,  Landlord's  obligation  to  so  restore  the  Premises  shall  be  limited  to  the  award  Landlord
receives in respect of such Taking that is not required to be applied to the indebtedness secured by a mortgage.  In the event of any such Taking, Landlord
shall be entitled to receive the entire price or award from any such Taking without any payment to Tenant, and Tenant hereby assigns to Landlord Tenant's
interest, if any, in such award, including, without limitation, any award for a Taking of Tenant's leasehold interest hereunder.  Tenant shall have the right, to

1111154v7

25

 
 
 
 
the  extent  that  same  shall  not  diminish  Landlord's  award,  to  make  a  separate  claim  against  the  condemning  authority  (but  not  Landlord)  for  such
compensation as may be separately awarded or recoverable by Tenant for (i) moving expenses, (ii) Tenant's interest in the unamortized value of the Tenant
Improvements and Tenant-Made Alterations (to the extent the same were paid solely by Tenant without the benefit of the Tenant Improvement Allowance or
any other funds by Landlord), and (iii) damage to Tenant's Trade Fixtures and personal property.  This paragraph shall be Tenant's sole and exclusive remedy
in the event of any taking and Tenant hereby waives any rights and the benefits of Section 1265.130 of the California Code of Civil Procedure or any other
statute granting Tenant specific rights in the event of a Taking which are inconsistent with the provisions of this Paragraph.

17.

Assignment and Subletting.

(a)

Without  Landlord's  prior  written  consent  which  consent  shall  not  be  unreasonably  withheld,  conditioned  or  unduly
delayed, Tenant shall not assign this Lease or sublease the Premises or any part thereof or mortgage, pledge, or hypothecate its leasehold interest or grant any
concession  or  license  within  the  Premises  (each  being  a  "Transfer")  and  any  attempt  to  do  any  of  the  foregoing  shall  be  void  ab  initio  and  of  no
effect.  Notwithstanding the above, Tenant may assign or sublet the Premises, or any part thereof, to any entity controlling Tenant, controlled by Tenant or
under common control with Tenant, or the surviving entity following a merger, consolidation or other reorganization of Tenant, or to an entity acquiring all or
substantially all of the stock (or other ownership interests) or assets of Tenant (each, a "Tenant Affiliate"), without the prior written consent of Landlord;
provided, however, Tenant shall provide at least ten (10) days written notice prior to assigning this Lease to, or entering into any sublease with, any Tenant
Affiliate and the Tenant Affiliate must have a tangible net worth reasonably sufficient to satisfy all of Tenant's remaining obligations under this Lease, as
reasonably  determined  by  Landlord.    Tenant  shall  reimburse  Landlord  for  all  of  Landlord's  reasonable  out-of-pocket  expenses  in  connection  with  any
Transfer, other than to a Tenant Affiliate, not to exceed $10,000 in Current Dollars in the aggregate for any particular Transfer.   Tenant acknowledges and
agrees that Landlord may withhold its consent to any proposed assignment or subletting for any reasonable basis including, but not limited to: (i) Tenant is in
default of this Lease beyond any applicable cure period provided in this Lease; (ii) the assignee is unwilling to assume in writing all of Tenant's obligations
hereunder; (iii) the assignee or subtenant has a financial condition which is reasonably unsatisfactory to Landlord or Landlord's mortgagee; (iv) the proposed
assignee or sublessee is of a character or reputation or engaged in a business which is not consistent with the Project and/or other institutional quality research
and development projects in the market area (as reasonably determined by Landlord); (v) Landlord or any affiliate of Landlord has historically had a negative
experience with the proposed assignee, subtenant or any affiliate thereof; and/or (vi) the Premises will be used for different purposes than those set forth in
Paragraph 3(a) or for a use requiring or generating Hazardous Materials (beyond what is expressly permitted under Paragraph 30 below) or in violation of
applicable Environmental Requirements.    

(b)

Notwithstanding any Transfer, Tenant shall at all times remain fully responsible and liable for the payment of the rent and
for compliance with all of Tenant's other obligations under this Lease (regardless of whether Landlord's approval has been obtained for any such Transfer).  In
the event that the rent due and payable by a sublessee or assignee (or a combination of the rental payable under such sublease or assignment plus any bonus or
other consideration therefor or incident thereto) exceeds the rental payable under this Lease, then Tenant shall be bound and obligated to pay Landlord as
additional rent hereunder fifty percent (50%) of such excess rental  and other excess consideration (which excess shall be calculated after first deducting all
actual and reasonable out-of-pocket costs paid by Tenant to procure the transferee, including, without limitation, market brokerage fees, reasonable legal fees,
the unamortized amount [amortized on a straight line basis over the Lease Term] of the amount expended by Tenant above and beyond the amount of the
Tenant  Improvement  Allowance  in  connection  with  the  Tenant  Improvements  located  in  the  space  to  be  transferred,  and  the  reasonable  cost  of  tenant
improvements to the extent performed for the transferee in order to procure the assignment or sublease) within ten (10) days following receipt thereof by
Tenant.  If such Transfer is for less than all of the Premises, such excess rental and other excess consideration shall be calculated on a rentable square foot
basis.

(c)

If  this  Lease  is  assigned  or  if  the  Premises  is  subleased  (whether  in  whole  or  in  part)  or  in  the  event  of  the  mortgage,
pledge, or hypothecation of Tenant's leasehold interest or grant of any concession or license within the Premises or if the Premises be occupied in whole or in
part by anyone other than Tenant, then upon a default by Tenant beyond any applicable cure and/or notice period hereunder, Landlord may collect rent from
the assignee, sublessee, mortgagee, pledgee, party to whom the leasehold interest was hypothecated, concessionaire or licensee or

1111154v7

other occupant and, except to the extent set forth in the preceding subparagraph, apply the amount collected to the next rent payable hereunder; and all such
rentals collected by Tenant shall be held in trust for Landlord and immediately forwarded to Landlord.  No such transaction or collection of rent or application
thereof by Landlord, however, shall be deemed a waiver of these provisions or a release of Tenant from the further performance by Tenant of its covenants,
duties, or obligations hereunder.  Any approved assignment or sublease shall be expressly subject to the terms and conditions of this Lease. Landlord's consent
to any Transfer shall not waive Landlord's rights as to any subsequent Transfers.  Notwithstanding anything to the contrary contained in this Lease, if Tenant
or any proposed transferee claims that Landlord has unreasonably withheld or delayed its consent under this Paragraph 17 or otherwise has breached or acted
unreasonably under this Paragraph 17, then Tenant shall have the right to seek any and all remedies available at law or in equity; provided, however, that
Tenant hereby waives any right at law or equity to terminate this Lease including, without limitation, its rights under Section 1995.310 of the California Civil
Code or under any similar law, statute or ordinance now or hereafter in effect.

(d)

Tenant shall have the right to sublease, without Landlord's prior written consent, up to twenty thousand (20,000) rentable
square feet of the Premises, in the aggregate (each, a "Permitted Subtenant"); provided that (i) the Permitted Subtenant uses such space only for the use
permitted by this Lease and for no other purpose (and the products and materials stored by the Permitted Subtenant do not exceed that permitted to be stored
by Tenant under applicable Legal Requirements); (ii) before the Permitted Subtenant commences occupancy of the Premises, Tenant shall notify Landlord in
writing of the Permitted Subtenant's identity and any other information reasonably requested by Landlord.  Tenant shall cause each Permitted Subtenant, and
each of its employees and licensees, to comply with the provisions of this Lease (including, without limitation, the insurance requirements under this Lease),
and  each  Permitted  Subtenant,  and  each  of  its  employees,  agents,  and  contractors,  shall  be  deemed  a  Tenant  Party  for  purposes  of  this  Lease  (including,
without limitation, Tenant's indemnification obligations under this Lease); and (iii) Tenant is not in default of this Lease beyond any applicable cure period
provided in this Lease.  No use or occupancy of any portion of the Premises by a Permitted Subtenant shall release or excuse Tenant from any obligation
hereunder or create a landlord/tenant relationship between Landlord and such Permitted Subtenant.  Landlord shall not be required to provide notices to any
Permitted Subtenant.  The foregoing consent by Landlord shall not be construed as a waiver of Landlord's right to consent to any further subletting either by
Tenant or by the any of the Permitted Subtenants or to any assignment by Tenant of the Lease or assignment by a Permitted Subtenant.

18.

Indemnification.

(a)

To the extent permitted by applicable Legal Requirements, but subject to the waiver of subrogation set forth in Paragraph
9(c)  above,  Tenant  agrees  to  indemnify,  defend  and  hold  harmless  Landlord  and  its  affiliates  and  their  investment  advisors,  members,  agents,  servants,
directors,  property  managers,  officers  and  employees  (collectively,  "Landlord Indemnitees"),  from  and  against  any  and  all  third  party  claims,  demands,
losses,  liabilities,  causes  of  action,  suits,  judgments,  damages,  costs  and  expenses  (including  without  limitation  reasonable  attorneys'  fees)  (collectively,
"Claims"), arising from any occurrence in or about the Premises, the use and occupancy of the Premises, or from any activity, work, or thing done, permitted
or suffered by Tenant and/or any Tenant Party in or about the Premises or the Project or due to any negligence or willful misconduct of Tenant or any Tenant
Party; provided, however, notwithstanding the foregoing, Tenant shall not have any obligation to indemnify Landlord or any Landlord Indemnitees for any
Claims to the extent caused by the negligence or willful misconduct of Landlord or any of the Landlord Indemnitees.  In case any Claim is brought against
Landlord  or  any  of  the  Landlord  Indemnitees  for  which  Tenant  is  obligated  to  indemnify  Landlord  and/or  the  Landlord  Indemnitees  pursuant  to  this
Paragraph, then Tenant, upon notice from Landlord, shall resist and defend such Claim (by counsel chosen by Tenant but reasonably satisfactory to Landlord)
at Tenant's expense.  Landlord shall not be liable to Tenant, and Tenant hereby waives all Claims against Landlord and the Landlord Indemnitees, for any
damages arising from any act, omission or neglect of any other tenant in the Project, and notwithstanding anything to the contrary contained in any provision
of this Lease, in no event shall Landlord or any of the Landlord Indemnitees be liable for any injury or interruption to Tenant's business or any loss of income
therefrom under any circumstances and neither Landlord nor any of the other indemnified parties shall be liable for any indirect, speculative, consequential or
punitive losses or damages suffered by Tenant or any Tenant Party.

To the extent permitted by applicable Legal Requirements, but subject to the waiver of subrogation set forth in Paragraph
9(c)  above,  Landlord  agrees  to  indemnify,  defend  and  hold  harmless  Tenant  and  its  affiliates  and  their  members,  agents,  servants,  directors,  property
managers, officers and employees (collectively, "Tenant Indemnitees"), from and against any and all Claims by third parties resulting from the negligence or
willful misconduct of Landlord or any Landlord Parties; provided, however, notwithstanding the foregoing or anything to the contrary in this Lease, Landlord
shall not have any obligation to indemnify Tenant or any Tenant Indemnitees for any Claims to the extent caused by the negligence or willful misconduct of
Tenant or any of the Tenant Indemnitees.  In case any Claim is brought against Tenant or any of the Tenant Indemnitees for which Landlord is obligated to
indemnify Tenant and/or the Tenant Indemnitees pursuant to this Paragraph, then Landlord, upon notice from Tenant, shall resist and defend such Claim (by
counsel chosen by Landlord but reasonably satisfactory to Tenant) at Landlord's expense.  

furnishing of insurance required hereunder shall not be deemed to limit either parties' obligations under this Paragraph 18.  

(c)

These  indemnity  provisions  shall  survive  termination  or  expiration  of  this  Lease  for  a  period  of  two  (2)  years.  The

19.

Inspection and Access.  Landlord and Landlord's agents, employees, and contractors shall have the right to enter the Premises at any
and all reasonable times and upon reasonable (but no less than 24-hours) advance written notice (except in the event of an emergency, in which case no notice
shall be required and/or given) for the purpose of inspecting the same, showing the same to prospective purchasers or lenders, or, during the last year of the
Lease Term, to prospective tenants, and for the purpose of exercising any right or obligation to maintain, repair or restore the Premises, or any other right
which Landlord may have under this Lease.  Tenant shall have the right to have a representative present during any entry upon the Premises by Landlord (and
absent an emergency, Landlord will reasonably coordinate with Tenant to schedule any visits to the Premises).  

20.

Quiet Enjoyment.  If Tenant shall perform, within the applicable notice and cure periods provided in this Lease, all of the covenants
and agreements herein required to be performed by Tenant, Tenant shall, subject to the terms of this Lease, any ground lease, mortgage or deed of trust now or
hereafter  encumbering  the  Premises  and  all  matters  of  record,  except  as  otherwise  expressly  provided  herein  (including,  without  limitation,  Paragraph  27
below), at all times during the Lease Term, have peaceful and quiet enjoyment of the Premises against any person claiming by, through or under Landlord, but
not otherwise.

21.

Surrender.  No act by Landlord shall be an acceptance of a surrender of the Premises, and no agreement to accept a surrender of the
Premises shall be valid unless it is in writing and signed by Landlord.  On or prior to the expiration or termination of the Lease Term or earlier termination of
Tenant's right of possession, Tenant shall surrender the Premises to Landlord in good condition, broom clean, reasonable wear and tear and casualty loss and
condemnation covered by Paragraphs 15 and 16, any damage caused by Landlord or any Landlord Parties excepted. Tenant shall remove (a) all Tenant-Made
Alterations  and  Permitted  Alterations  for  which  Landlord  has  advised  (or  is  deemed  to  have  advised)  Tenant  that  removal  would  be  required  pursuant  to
Paragraph 12(d) above, (b) all Tenant Improvements and Tenant Changes for which Landlord has advised (or is deemed to have advised) Tenant that removal
would  be  required  pursuant  to  Exhibit B  attached  hereto  (excluding  the  Improvements  Not  Subject  to  Restoration,  which  Tenant  shall  not  be  required  to
remove), and (c) all of Tenant's personal property and Trade Fixtures and security system(s).  Landlord and Tenant agree to have a joint inspection of the
Premises prior to Tenant vacating.  In the event of Tenant's failure to participate in such joint inspection after Tenant's receipt of notice from Landlord thereof,
and Tenant's subsequent failure to participate in such joint inspection within ten (10) business days after such notice, Landlord's inspection shall be deemed
conclusive for purposes of determining Tenant's responsibility for repairs and restoration.  No such performance by Landlord shall create any liability on the
part  of  Landlord  whatsoever.  Any  Trade  Fixtures,  Tenant-Made  Alterations,  Tenant  Improvements,  Tenant  Changes,  Permitted  Alterations  and  all  other
personal property not so removed by Tenant as permitted or required herein shall be deemed abandoned and may be stored, removed, and disposed of by
Landlord at Tenant's expense, and Tenant waives all claims against Landlord for any damages resulting from Landlord's retention and/or disposition of such
property.   All  obligations  of  Tenant  hereunder  not  fully  performed  as  of  the  expiration  or  termination  of  the  Lease  Term  shall  survive  the  expiration  or
termination  of  the  Lease  Term,  including  without  limitation,  indemnity  obligations,  payment  obligations  with  respect  to  Operating  Expenses  and  all
obligations concerning the condition and repair of the Premises. If Tenant fails to perform any obligation contained herein prior to the expiration or earlier
termination of this Lease, without limiting any of the other rights and remedies Landlord may under this Lease, at law and/or in equity, Landlord shall have
the rights set forth in Paragraph 24(f) below.

1111154v7

28

 
 
 
 
22.

Holding Over.  If Tenant fails to vacate the Premises after the expiration or earlier termination of the Lease Term, Tenant shall be, at
Landlord's sole election, a tenant at will or at sufferance, and Tenant shall pay, in addition to any other rent or other sums then due Landlord, Base Rent equal
to one hundred twenty-five percent (125%) of the Base Rent in effect on the expiration or termination date computed on a monthly basis for the first month or
part thereof during such holdover, and one hundred fifty percent (150%) for each month or part thereof thereafter, even if Landlord consents to such holdover
(which  consent  shall  be  effective  only  if  in  writing).   All  other  payments  shall  continue  under  the  terms  of  this  Lease.   Tenant  shall  also  be  liable  for  all
Operating Expenses incurred during such holdover period.  In addition, if Tenant does not vacate the Premises within thirty (30) days following the expiration
or  earlier  termination  of  the  Lease  Term,  Tenant  shall  be  liable  for  all  damages  (including  attorneys'  fees  and  expenses)  of  whatever  type  (including
consequential damages) incurred by Landlord as a result of such holding over.  No holding over by Tenant, whether with or without consent of Landlord,
shall  operate  to  extend  this  Lease  except  as  otherwise  expressly  provided,  and  this  Paragraph  22  shall  not  be  construed  as  consent  for  Tenant  to  retain
possession of the Premises.

23.

Events of Default.  Each of the following events shall be an event of default ("Event of Default") by Tenant under this Lease:

following written notice from Landlord.  

(a)

Tenant shall fail to pay any installment of Base Rent or any other payment required herein within five (5) business days

(b)

Any insurance required to be maintained by Tenant pursuant to this Lease shall be canceled or terminated or shall expire
or shall be reduced below the levels required hereunder, except, in each case, as permitted in this Lease and Tenant has not obtained replacement coverage
(effective retroactively to the date of termination or cancellation of the prior policy), within ten (10) days following its receipt of written notice from either
Landlord or the applicable insurance carrier.

as otherwise permitted in this Lease) that is not voided and cured within five (5) days following written notice from Landlord.

(c)

There shall occur any assignment, subleasing or other transfer of Tenant's interest in or with respect to this Lease (except

(25) days after Tenant is notified (or otherwise actually becomes aware) that any such lien or encumbrance is filed against the Premises.

(d)

Tenant shall fail to discharge or bond over any lien placed upon the Premises in violation of this Lease within twenty-five

Tenant  shall  fail  to  execute  any  instrument  of  subordination  or  attornment  or  any  estoppel  certificate  within  the  time
periods set forth in Paragraphs 27 and 29 respectively following Landlord's request for the same where such failure continues for more than ten (10) business
days after notice from Landlord.

(e)

(f)

Tenant shall fail to comply with any provision of this Lease other than those specifically referred to in this Paragraph 23,
and except as otherwise expressly provided herein, such default shall continue for more than thirty (30) days after Landlord shall have given Tenant written
notice  of  such  default;  provided,  however,  that  if  the  nature  of  Tenant's  obligation  under  this  subsection  (g)  is  such  that  more  than  thirty  (30)  days  are
reasonably required for performance, then Tenant shall not be in default under this subparagraph (f) if Tenant promptly commences performance within such
thirty (30) day period and thereafter diligently prosecutes the same to completion.

Any notices to be provided by Landlord under this Paragraph 23 shall be in addition to, and not in lieu of, any notice required under Section 1161 et seq. of
the California Code of Civil Procedure.

24.

Landlord's Remedies.    Upon  the  occurrence  of  any  Event  of    Default,  Landlord  shall  have  the  following  rights  and  remedies,  in
addition to those allowed by law or in equity, any one or more of which may be exercised or not exercised without precluding Landlord from exercising any
other remedy provided in this Lease or otherwise allowed by law or in equity:

1111154v7

29

 
 
 
 
(a)

Termination of Lease.  Landlord may terminate this Lease and Tenant's right to possession of the Premises.  If Tenant
has abandoned and vacated the Premises, the mere entry of the Premises by Landlord in order to perform acts of maintenance, cure defaults, preserve the
Premises or to attempt to relet the Premises, or the appointment of a receiver in order to protect Landlord's interest under this Lease, shall not be deemed a
termination  of  Tenant's  right  to  possession  or  a  termination  of  this  Lease  unless  Landlord  has  notified  Tenant  in  writing  that  this  Lease  is
terminated.    Notification  of  any  default  described  in  Paragraph  23  of  this  Lease  shall  be  in  lieu  of,  and  not  in  addition  to,  any  notice  required  under
Section 1161 et seq. of the California Code of Civil Procedure.  If Landlord terminates this Lease and Tenant's right to possession of the Premises, Landlord
may recover from Tenant:

(1)

(2)

The worth at the time of the award of unpaid rent which had been earned at the time of termination; plus

The worth at the time of the award of the amount by which the unpaid rent which would have been earned after

termination until the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus

after the time of the award exceeds the amount of such rental loss that Tenant proves could be reasonably avoided; plus

(3)

The worth at the time of the award of the amount by which the unpaid rent for the balance of the Lease Term

(4)

Any  other  amounts  necessary  to  compensate  the  Landlord  for  all  of  the  detriment  proximately  caused  by
Tenant's failure to perform its obligations under this Lease or which in the ordinary course of things would be likely to result therefrom, including
any  legal  expenses,  brokers  commissions  or  finders  fees  to  the  extent  allocable  to  the  remaining  Lease  Term,  the  costs  of  repairs,  cleanup,
refurbishing, removal and storage or disposal of Tenant's personal property, equipment, fixtures and anything else that Tenant is required under
this Lease to remove but does not remove (including those alterations which Tenant is required to remove pursuant to an election by Landlord and
Landlord  actually  removes  whether  notice  to  remove  shall  be  delivered  to  Tenant),  and  any  costs  for  alterations,  additions  and  renovations
incurred  by  Landlord  in  regaining  possession  of  and  reletting  (or  attempting  to  relet)  the  Premises  in  each  case  to  the  extent  allocable  to  the
remaining Lease Term.    

All  computations  of  the  "worth  at  the  time  of  the  award"  of  amounts  recoverable  by  Landlord  under  (1)  and  (2)  hereof  shall  be  computed  by
allowing interest at the lesser of the highest rate permitted by applicable law or ten percent (10%) per annum (the "Interest Rate").  The "worth at the time of
the award" recoverable by Landlord under (3) and the discount rate for purposes of determining any amounts recoverable under (4), if applicable, shall be
computed by discounting the amount recoverable by Landlord at the discount rate of the Federal Reserve Bank, San Francisco, California, at the time of the
award plus one percent (1%).  

Upon termination of this Lease, whether by lapse of time or otherwise, Tenant shall immediately vacate the Premises and deliver possession to

Landlord, and Landlord shall have the right to re-enter the Premises.

(b)

Lease to Remain in Effect.  Notwithstanding Landlord's right to terminate this Lease, Landlord may, at its option, even
though an Event of Default has occurred and Tenant has abandoned the Premises, continue this Lease in full force and effect and not terminate Tenant's right
to possession, and enforce all of Landlord's rights and remedies under this Lease.  In such event, Landlord shall have the remedy described in California Civil
Code Section 1951.4 (Landlord may continue the Lease in effect after Tenant's breach and abandonment and recover rent as it becomes due, if Tenant has a
right  to  sublet  or  assign,  subject  only  to  reasonable  limitations).    Further,  in  such  event  Landlord  shall  be  entitled  to  recover  from  Tenant  all  costs  of
maintenance  and  preservation  of  the  Premises,  and  all  costs,  including  without  limitation  attorneys'  fees  and  receivers'  fees,  incurred  in  connection  with
appointment  of  and  performance  by  a  receiver  to  protect  the  Premises  and  Landlord's  interest  under  this  Lease.    No  re-entry  or  taking  possession  of  the
Premises by Landlord shall be construed as an election to terminate this Lease unless a notice (signed by a duly authorized representative of Landlord) of
intention to terminate this Lease is given to Tenant.

(c)

All Sums Collectible as Rent.  All sums due and owing to Landlord by Tenant under this Lease shall be collectible by

Landlord as rent.

1111154v7

30

 
 
 
 
(d)

No Surrender.  No act or omission by Landlord or its agents during the Lease Term shall be an acceptance of a surrender
of the Premises, and no agreement to accept a surrender of the Premises shall be valid unless made in writing and signed by a duly authorized representative
of  Landlord.    Landlord  shall  be  entitled  to  a  restraining  order  or  injunction  to  prevent  Tenant  from  defaulting  under  any  of  its  obligations  other  than  the
payment of rent or other sums due hereunder.

(e)

Effect  of  Termination.    Neither  the  termination  of  this  Lease  nor  the  exercise  of  any  remedy  under  this  Lease  or
otherwise available at law or in equity shall affect Landlord's right of indemnification set forth in this Lease or otherwise available at law or in equity for any
act or omission of Tenant, and all rights to indemnification and other obligations of Tenant intended to be performed after termination of this Lease shall
survive termination of this Lease.

(f)

Perform Tenant Repairs.  At Landlord's election, without limiting any of Landlord's other remedies, if Tenant fails to
perform  any  repair,  restoration,  maintenance  or  replacement  for  which  it  is  responsible  under  this  Lease  within  the  time  periods  set  forth  in  this  Lease
(including, without limitation, all notice and cure periods), Landlord may (but shall not be obligated to) perform such repair, maintenance or replacement, as
applicable, on Tenant's behalf, in which case Tenant shall reimburse Landlord for all costs incurred by Landlord within thirty (30) days after demand therefor
(which demand shall be accompanied by reasonable supporting documentation).  

(g)

Waiver of Redemption by Tenant.  In the event Landlord exercises any one or more of Landlord's rights and remedies
under this Article 24, Tenant expressly waives (for Tenant and for all those claiming under Tenant) any and all rights of redemption or relief from forfeiture
under California Code of Civil Procedure Section 1174 or 1179, or granted by or under any present or future laws, and further releases Landlord from any and
all claims, demands and liabilities by reason of such exercise by Landlord.

25.

Tenant's Remedies/Limitation of Liability.  Landlord shall not be in default hereunder unless Landlord fails to perform any of its
obligations hereunder within thirty (30) days after written notice from Tenant specifying such failure (unless such performance will, due to the nature of the
obligation, require a period of time in excess of thirty (30) days, then such additional period of time as is reasonably necessary).  All obligations of Landlord
hereunder shall be construed as covenants, not conditions.  Except as expressly provided otherwise in this Lease, Tenant hereby waives the benefit of any
laws granting it the right to perform Landlord's obligations or withhold rent on account of any Landlord default.  The term "Landlord" in this Lease shall
mean  only  the  owner,  for  the  time  being  of  the  Premises,  and  in  the  event  of  the  transfer  by  such  owner  of  its  interest  in  the  Premises,  such  owner  shall
thereupon be released and discharged from all obligations of Landlord thereafter accruing; provided, however, such obligations shall be binding during the
Lease Term upon such new owner during the duration of such owner's ownership.  Any liability of Landlord (and its partners, shareholders or members) to
Tenant (or any person or entity claiming by, through or under Tenant), and damages therefor, for any default by Landlord under this Lease or arising out of the
relationship between Landlord and Tenant shall be limited solely to Tenant's actual direct, but not consequential, indirect, speculative, or punitive damages
therefor  and  shall  be  recoverable  only  from  Landlord's  equity  interest  in  the  Building  (including  any  rental,  condemnation,  sales  and  insurance  proceeds
received therefrom), and in no event shall any personal liability be asserted against Landlord, its partners, shareholders, members, directors, employees or
agents in connection with this Lease nor shall any recourse be had to any other property or assets of Landlord.  

26.

Waiver of Jury Trial; Judicial Reference.  TO THE FULLEST EXTENT PERMITTED BY LAW, TENANT AND LANDLORD
WAIVE  ANY  RIGHT  TO  TRIAL  BY  JURY  OR  TO  HAVE  A  JURY  PARTICIPATE  IN  RESOLVING  ANY  DISPUTE,  WHETHER  SOUNDING  IN
CONTRACT, TORT, OR OTHERWISE, BETWEEN LANDLORD AND TENANT ARISING OUT OF THIS LEASE OR ANY OTHER INSTRUMENT,
DOCUMENT, OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS RELATED HERETO.  

1111154v7

27.

Subordination.

(a)

Landlord  represents  and  warrants  to  Tenant  that  no  mortgage  (as  defined  below)  encumbers  the  Premises  as  of  the
Effective Date.  This Lease and Tenant's interest and rights hereunder are and shall be subject and subordinate at all times to the lien of any deed of trust or
mortgage  or  any  ground  lease,  now  existing  or  hereafter  created  on  or  against  the  Project  or  the  Premises,  and  all  amendments,  restatements,  renewals,
modifications,  consolidations,  refinancing,  assignments  and  extensions  thereof,  without  the  necessity  of  any  further  instrument  or  act  on  the  part  of
Tenant.  The subordination of this Lease to any such future ground or underlying leases of the Project or Premises or to the lien of any mortgage, trust deed or
other encumbrances, shall be subject to Tenant's receipt of a commercially reasonable subordination, non-disturbance, and attornment agreement in favor of
Tenant. Tenant  agrees,  at  the  election  of  the  holder  of  any  such  mortgage,  to  attorn  to  any  such  holder.  The  provisions  of  this  Paragraph  27  shall  be  self-
operative and no further instrument shall be required to effect such subordination or attornment; however, Tenant agrees to execute, acknowledge and deliver
such instruments, confirming such subordination and such instruments of attornment as shall be requested by any such holder within ten (10) business days of
such request.  

(b)

Notwithstanding the foregoing, any such holder may at any time subordinate its mortgage to this Lease, without Tenant's
consent, by notice in writing to Tenant, and thereupon this Lease shall be deemed prior to such mortgage without regard to their respective dates of execution,
delivery or recording and in that event such holder shall have the same rights with respect to this Lease as though this Lease had been executed prior to the
execution,  delivery  and  recording  of  such  mortgage  and  had  been  assigned  to  such  holder.    The  term  "mortgage"  whenever  used  in  this  Lease  shall  be
deemed  to  include  deeds  of  trust,  security  assignments  and  any  other  encumbrances,  and  any  reference  to  the  "holder"  of  a  mortgage  shall  be  deemed  to
include the beneficiary under a deed of trust.

Tenant  shall  not  seek  to  enforce  any  remedy  it  may  have  for  any  default  on  the  part  of  Landlord  without  first  giving
written notice by certified mail, return receipt requested, or by overnight courier, specifying the default in reasonable detail to any mortgage holder whose
address has been given to Tenant, and affording such mortgage holder a reasonable opportunity to perform Landlord's obligations hereunder.  

(c)

28.

Mechanic's Liens.  Tenant has no express or implied authority to create or place any lien or encumbrance of any kind upon, or in any
manner to bind the interest of Landlord or Tenant in, the Premises or to charge the rentals payable hereunder for any claim in favor of any person dealing with
Tenant, including those who may furnish materials or perform labor for any construction or repairs.  Landlord may record, at its election, notices of non-
responsibility pursuant to California Civil Code Section 8444 in connection with any work performed by Tenant.  Tenant covenants and agrees that it will pay
or cause to be paid all sums legally due and payable by it on account of any labor performed or materials furnished in connection with any work performed on
the Premises and that it will save and hold Landlord harmless from all loss, cost or expense based on or arising out of asserted claims or liens against the
leasehold estate or against the interest of Landlord in the Premises or under this Lease.  Tenant shall give Landlord immediate written notice of the placing of
any lien or encumbrance against the Premises and cause such lien or encumbrance to be discharged within twenty-five (25) days after Tenant is notified (or
otherwise  actually  becomes  aware)  of  the  filing  or  recording  thereof;  provided,  however,  Tenant  may  contest  such  liens  or  encumbrances  as  long  as  such
contest prevents foreclosure of the lien or encumbrance and Tenant causes such lien or encumbrance to be bonded or insured over in a manner satisfactory to
Landlord within such period. Without limiting any other rights or remedies of Landlord, if Tenant fails for any reason to cause a lien or encumbrance to be
discharged within twenty-five (25) days after Tenant is notified (or otherwise actually becomes aware) of the filing or recording thereof, then Landlord may
take such action(s) as it deems necessary to cause the discharge of the same (including, without limitation, by paying any amount demanded by the party who
has filed or recorded such lien or encumbrance, regardless of whether the same is in dispute), and Landlord shall be reimbursed by Tenant for all costs and
expenses incurred by Landlord in connection therewith within five (5) business days following written demand therefor.

29.

Estoppel Certificates.  Tenant and Landlord each agrees, from time to time, within ten (10) business days after request of the other
party (the "Requesting Party"), to execute and deliver to the Requesting Party, or its designee, any estoppel certificate requested by the Requesting Party ,
stating that this Lease is in full force and effect, the date to which rent has been paid, that the Requesting Party is not in default hereunder (or specifying in
detail the nature of any such default), the termination date of this Lease and such other matters pertaining to this Lease as may be requested by the Requesting
Party.

Environmental Requirements.  

(a)

Prior  to  Tenant's  entry  into  the  Premises,  Tenant  shall  fully  and  accurately  complete  Landlord's  Pre-Leasing
Environmental Questionnaire ("Environmental Questionnaire")  attached  hereto  as  Exhibit C,  which  when  so  completed,  shall  be  incorporated  herein  by
reference.  Tenant hereby represents, warrants and covenants that except for (i) those chemicals or materials, and their respective approximate quantities listed
on  the  Environmental  Questionnaire  (as  the  same  may  be  updated  from  time  to  time  as  provided  below)  or  any  similar  chemicals  or  materials  used  for
substantially the same purposes in substitution thereof in compliance with Environmental Requirements, and (ii) Hazardous Materials that are used by Tenant
for  ordinary  cleaning,  for  office  purposes  and  warehouse  maintenance  purposes  in  compliance  with  all  Environmental  Requirements  (as  defined  below),
Tenant  will  not  use,  store  or  generate  any  "Hazardous  Materials"  (as  defined  below)  in,  on,  under  or  about  the  Premises  and/or  Project.    Tenant  further
represents, warrants and covenants that except for those chemicals and materials, and the approximate quantities listed on the Environmental Questionnaire
(as  the  same  may  be  updated  from  time  to  time  as  provided  below)  or  any  similar  chemicals  or  materials  used  for  substantially  the  same  purposes  in
substitution thereof in compliance with Environmental Requirements, and the Hazardous Materials described in the immediately preceding sentence that are
used  and  stored  in  compliance  with  Environmental  Requirements,  Tenant  shall  not  cause  or  permit  any  Hazardous  Materials  to  be  brought  upon,  placed,
stored, manufactured, generated, blended, handled, recycled, disposed of, used or released on, in, under or about the Premises and/or Project by Tenant or its
agents, employees, contractors, subcontractors, subtenants, assigns or invitees.  Tenant shall notify Landlord prior to using any Hazardous Materials in the
Premises not described on the initial Environmental Questionnaire, and such use shall be subject to compliance with Environmental Requirements and all of
the  provisions  of  this  Lease.    Tenant  shall  operate  its  business  in  the  Premises  in  full  compliance  with  all  Environmental  Requirements  (as  defined
below).  Landlord acknowledges that, subject to compliance with Legal Requirements, Private Restrictions, and the other terms and conditions contained in
this  Lease  (including,  without  limitation,  Paragraph  12  above),  Tenant  may  install  and  use  fume  hoods  in  the  Premises,  and  that  emissions  of  Hazardous
Materials into the air in compliance with all Environmental Requirements shall not be considered releases.  Landlord agrees to keep the information on the
Environmental Questionnaire confidential in accordance with the terms of Paragraph 42 below.  

(b)

The  term  "Environmental  Requirements"  means  all  applicable  present  and  future  statutes,  regulations,  ordinances,
rules, codes, judgments, permits, authorizations, orders, policies or other similar requirements of any governmental authority, agency or court regulating or
relating to health, safety, or environmental conditions on, under, or about the Premises or the environment, including without limitation, the following:  the
Comprehensive Environmental Response, Compensation and Liability Act; the Resource Conservation and Recovery Act; the Clean Air Act; the Clean Water
Act; the Toxic Substances Control Act and all state and local counterparts thereto, and any common or civil law obligations including, without limitation,
nuisance or trespass, and any other requirements of Paragraphs 3 and 31 of this Lease.  The term "Hazardous Materials" means and includes any substance,
material, waste, pollutant, or contaminant  that is or could be regulated under any Environmental Requirement, including, without limitation, any solid or
hazardous waste, hazardous substance, asbestos, petroleum (including crude oil or any fraction thereof, natural gas, synthetic gas, polychlorinated biphenyls
(PCBs), and radioactive material).  For purposes of Environmental Requirements, to the extent authorized by law, Tenant is and shall be deemed to be the
responsible party, including without limitation, the "owner" and "operator" of Tenant's "facility" and the "owner" of all Hazardous Materials brought on the
Premises  by  Tenant  or  any  Tenant  Party,  and  the  wastes,  by-products,  or  residues  generated,  resulting,  or  produced  therefrom  ("Tenant  Hazardous
Materials").

(c)

Without  limiting  the  generality  of  Tenant's  obligation  to  comply  with  laws  as  otherwise  provided  in  this  Lease,  Tenant
shall, at its sole cost and expense, comply with all present and future Environmental Requirements related to the use of Hazardous Materials by Tenant and/or
any Tenant Party; provided that Tenant shall not be required to treat, remediate, and/or encapsulate any Pre-Existing Hazardous Materials or any Landlord
Caused  Hazardous  Materials  (as  such  terms  are  defined  below).    Tenant  shall  obtain  and  maintain  any  and  all  necessary  government  permits,  licenses,
certifications  and  approvals  appropriate  or  required  for  the  use,  handling,  storage,  and  disposal  of  any  Hazardous  Materials  used,  stored,  generated,
transported, handled, blended, or recycled by Tenant on the Premises or Project.  Landlord shall have a continuing right, without obligation, to require Tenant
to obtain, and to review and inspect any and all such permits, licenses, certifications and approvals, together with copies of any and all Hazardous Materials
management plans and programs, any and all Hazardous Materials risk management and pollution prevention programs, and any and all Hazardous Materials
emergency  response  and  employee  training  programs  respecting  Tenant's  use  of  Hazardous  Materials.    Upon  request  of  Landlord  (but  no  more  than  once
every Lease Year, unless Landlord shall have reasonable grounds to believe that Tenant is not in compliance with its

1111154v7

33

 
 
 
 
covenants under this Paragraph 30), Tenant shall deliver to Landlord, a narrative description explaining the nature and scope of Tenant's activities involving
Hazardous Materials and showing to Landlord's reasonable satisfaction compliance with all Environmental Requirements and the terms of this Lease.

(d)

Unless Tenant is required by law to give earlier notice to Landlord, Tenant shall notify Landlord in writing as soon as
possible but in no event later than five (5) days after (1) the occurrence of any spill, discharge, leak, seep or any other release of any Hazardous Material on,
under, from or about the Premises or Project, in violation of Environmental Requirements, regardless of the quantity of any such spill, discharge, leak, seep or
release of Hazardous Material, or (2) Tenant becomes aware of any regulatory inquiries, inspections, investigations, directives, or any cleanup, compliance or
abatement  proceedings  (including  any  threatened  or  potential  investigations  or  proceedings),  or  claims  by  any  third  parties  relating  to  violation  of
Environmental Requirements relating to any Hazardous Materials in, on, under, from or about the Project or Premises.  Landlord shall have the right to appear
at and participate in, any and all legal or other administrative proceedings concerning the release of any Hazardous Materials on, under, from or about the
Premises or Project.

(e)

To  the  extent  Tenant  or  a  Tenant  Party  discovers  any  material  water  leakage,  water  damage  or  mold  in  or  about  the
Premises or Project, Tenant shall promptly notify Landlord thereof in writing.  If any spill, discharge, leak, seep or any other release of any Tenant Hazardous
Materials on, under, from or about the Premises or Project shall occur, in addition to notifying Landlord as specified herein, Tenant, at its own sole cost and
expense, shall (1) immediately comply with any and all reporting requirements imposed pursuant to any and all Environmental Requirements, (2) provide a
written  certification  to  Landlord  indicating  that  Tenant  has  complied  with  all  applicable  reporting  requirements,  and  (3)  take  any  and  all  necessary
investigation, corrective and remedial action in accordance with any and all applicable Environmental Requirements, utilizing an environmental consultant
approved  by  Landlord,  and  (4)  take  any  such  additional  investigative,  remedial  and  corrective  actions  as  Landlord  shall  in  its  reasonable  discretion  deem
necessary.      Landlord  may,  as  required  by  any  and  all  Environmental  Requirements,  report  the  unauthorized  spill,  discharge,  leak,  seep  or  any  other
unauthorized release of any Hazardous Material to the appropriate regulatory agencies identifying the Tenant as the responsible party.  Tenant shall deliver to
Landlord copies of all administrative orders, notices, demands, directives or other communications directed to Tenant from any governmental authority in
respect  of  any  release,  discharge,  or  spill  of  any  Hazardous  Material  on,  under,  from,  or  about  the  Premises  or  Project,  together  with  copies  of  all
investigation, assessment, and remediation plans and reports prepared by or on behalf of Tenant in response to any such regulatory order or directive.

(f)

If Landlord has a reasonable basis for believing Tenant is not in compliance with its obligations under this Section 30,
then pursuant to the terms and conditions contained in Paragraph 19 above, Landlord shall have access to, and a right to perform inspections and tests of, the
Premises to determine Tenant's compliance with Environmental Requirements, its obligations under this Paragraph 30, or the environmental condition of the
Premises.   Access  shall  be  granted  to  Landlord  upon  Landlord's  prior  notice  to  Tenant  in  accordance  with  Paragraph 19  above  (except  in  the  event  of  an
emergency, in which case only such notice as is reasonable under the circumstances, if any, shall be required), and at such times so as to minimize, so far as
may  be  reasonable  under  the  circumstances,  any  disturbance  to  Tenant's  operations.    Such  inspections  and  tests  shall  be  conducted  at  Landlord's  expense,
unless  such  inspections  and  tests  reveal  that  Tenant  has  breached  or  violated  the  provisions  of  this  Paragraph 30,  in  which  event  Tenant  shall  reimburse
Landlord  for  the  costs  and  expenses  incurred  by  Landlord  in  connection  with  such  inspections  or  tests.    Landlord's  receipt  of  or  satisfaction  with  any
environmental assessment in no way waives any rights that Landlord holds against Tenant.  Without limiting the foregoing, Landlord may separately engage
its  own  environmental  consultant  or  consultants  at  Landlord's  expense  (without  reimbursement  from  Tenant  as  an  Operating  Expense)  to  investigate  and
advise  Landlord  respecting  any  release,  discharge,  or  spill  of  Hazardous  Materials  on,  under,  from,  or  about  the  Premises  or  Project,  or  to  independently
investigate  any  regulatory  inquiries,  directives,  or  investigations  regarding  Tenant's  use,  handling,  storage,  or  disposal  of  Hazardous  Materials;  provided,
however, if such investigations reveal that Tenant has not complied with any Environmental Requirement or the provisions of this Paragraph 30, then Tenant
shall reimburse Landlord for the costs of such consultants and investigations.   Tenant shall not conduct any invasive environmental testing or investigation
(including, without limitation, any testing of any soils) on or about the Project without obtaining Landlord's prior written consent, and any investigations or
remediation on or about the Project shall be conducted only by a consultant approved in writing by Landlord and pursuant to a work letter approved in writing
by Landlord.

(g)

Notwithstanding  anything  to  the  contrary  contained  herein,  if  Tenant  fails  to  cure  or  commence  a  cure  within  ten  (10)
days of written notice from Landlord (and thereafter diligently prosecute such cure to completion), Landlord shall have the right (but not the obligation) to
enter  upon  the  Premises  and  cure  any  non-compliance  by  Tenant  with  the  terms  of  this  Paragraph 30  or  any  Environmental  Requirements  or  any  release,
discharge,  spill,  improper  use,  storage,  handling  or  disposal  of  Hazardous  Materials  on,  under,  from,  or  about  the  Premises  or  Project,  regardless  of  the
quantity of any such release, discharge, spill, improper use, storage, handling or disposal of Hazardous Materials on or about the Premises or Project, the full
cost of which shall be deemed to be rent and shall be due and payable by Tenant to Landlord immediately upon demand.

If  any  information  provided  to  Landlord  by  Tenant  on  the  Environmental  Questionnaire,  or  otherwise  relating  to
information  concerning  Hazardous  Materials  is  false,  incomplete,  or  misleading  in  any  material  respect,  the  same  shall  be  deemed  an  event  of  default  by
Tenant under this Lease.

(h)

(i)

Upon  termination  of  this  Lease,  Tenant,  at  its  own  cost  and  expense  and  in  compliance  with  all  Environmental
Requirements, shall cause any and all Hazardous Materials stored on, under, upon or about the Premises or Project to be removed in a manner and to a level
which  complies  with  all  Environmental  Requirements  and  does  not  limit  any  future  uses  of  the  Premises  or  Project  or  require  the  recording  of  any  deed
restriction or notice regarding the Premises or Project.  Upon prior notice and approval by the Landlord, Tenant shall, at its own cost and expense and in
compliance with all Environmental Requirements, remove any contaminated equipment, furnishings, and fixtures from the Premises including any and all
storage containers and facilities used in connection with Tenant's use of Hazardous Materials from the Premises.

(j)

Without limiting in any way Tenant's obligations under any other provision of this Lease, Tenant and its successors and
assigns shall indemnify, protect, defend and hold Landlord and the Landlord Indemnitees harmless from any and all third party Claims, judgments, damages,
penalties,  enforcement  actions,  taxes,  fines,  remedial  actions,  liabilities,  losses,  costs  and  expenses  (including,  without  limitation,  actual  attorneys'  fees,
litigation,  arbitration  and  administrative  proceeding  costs,  expert  and  consultant  fees,  laboratory  costs,  remediation,  removal,  repair,  corrective  action,  or
cleanup expenses) and sums paid in settlement of Claims including, without limitation, damages arising out of the diminution in the value of the Premises or
Project or any portion thereof, damages for the loss of the Premises or Project, damages arising from any adverse impact on the marketing of space in the
Premises or Project, and sums paid in settlement of claims, which arise during or after the Lease Term in whole or in part as a result of the presence or release
of Tenant Hazardous Materials, in, on, under, from or about the Premises or the Project and/or other adjacent properties, or any breach of the requirements of
this Paragraph 30 by Tenant or any Tenant Party.  The obligations of Tenant under this Paragraph 30 shall survive any termination of this Lease.

(k)

Notwithstanding  anything  to  the  contrary  contained  herein,  Tenant  shall  not  be  responsible  to  remediate  or  indemnify
Landlord with respect to any environmental condition existing at the Premises or the Project prior to the Effective Date of this Lease that is in violation of
Environmental  Requirements  ("Pre-Existing  Hazardous  Materials")  and/or  the  release  of  Hazardous  Materials  by  Landlord  or  any  Landlord  Parties
affecting the Premises or the Project and in violation of Environmental Requirements ("Landlord Caused Hazardous Materials"); provided, however, Pre-
Existing Hazardous Materials and Landlord Caused Hazardous Materials shall not include any Hazardous Materials that are negligently released by Tenant
and/or  any  Tenant  Party.    To  the  extent  that  any  Pre-Existing  Hazardous  Materials  and/or  Landlord  Caused  Hazardous  Materials  are  discovered  at  the
Premises and/or the Project and the remediation of the same is required by a governmental authority with jurisdiction, then Landlord shall remediate the Pre-
Existing  Hazardous  Materials  and/or  the  Landlord  Caused  Hazardous  Materials,  as  applicable  (to  the  extent  required  by  the  applicable  governmental
authority), at Landlord's sole cost and expense (and not included in Operating Expenses), which shall be Tenant's sole and exclusive remedy in connection
therewith.    Landlord  shall  perform  such  remediation  in  such  manner  and  take  commercially  reasonable  measures  to  avoid  materially  disrupting  Tenant's
business operations at the Premises.   Nothing in this Paragraph shall be interpreted as imposing any liability on Landlord for any consequential damages
including any lost sales or profits of Tenant.

and regulations at any time or from time to time established by Landlord covering use of the Premises and the Project.  The current rules and regulations are

32.

Security  Service.    Tenant  acknowledges  and  agrees  that,  while  Landlord  may  (but  shall  not  be  obligated  to)  patrol  the  Project,
Landlord is not providing any security services with respect to the Premises and that Landlord shall not be liable to Tenant for, and Tenant waives any claim
against Landlord with respect to, any loss by theft or any other damage suffered or incurred by Tenant in connection with any unauthorized entry into the
Premises or any other breach of security with respect to the Premises.  Tenant shall be solely responsible (at Tenant's sole cost and expense) for complying
with  all  Legal  Requirements  and  Private  Restrictions  with  respect  to  securing  the  Premises  and  the  installation  of  any  security  systems  and/or  cameras
required by Legal Requirements and/or Private Restrictions.  

33.

Force Majeure.  Except with respect to (i) monetary obligations (including, without limitation, Tenant's obligation to pay Base Rent
and Operating Expenses), (ii) Tenant's obligation to timely vacate and surrender the Premises upon the expiration or earlier termination of this Lease, (iii) the
obligation to obtain and maintain insurance as required by this Lease, and (iv) Tenant Delays and Landlord Delays (which are addressed elsewhere in this
Lease  and  in  the  Work  Letter  attached  hereto  as  Exhibit  B),  neither  Landlord  nor  Tenant  shall  be  held  responsible  for  delays  in  the  performance  of  its
obligations hereunder when caused by strikes, lockouts, labor disputes, acts of God, inability to obtain labor or materials or reasonable substitutes therefor,
governmental  restrictions,  governmental  regulations,  governmental  controls,  utility  company  delays,  delays  by  governmental  and/or  municipal  entities  or
agencies (including, without limitation any quasi-governmental entities such as any design review committees and/or owners associations associated with the
Project),  delay  in  issuance  of  permits  or  approvals,  enemy  or  hostile  governmental  action,  civil  commotion,  inclement  weather,  fire or other casualty, and
other causes beyond the reasonable control of Landlord or Tenant, as applicable ("Force Majeure").  

34.

Entire Agreement.   This  Lease  constitutes  the  complete  and  entire  agreement  of  Landlord  and  Tenant  with  respect  to  the  subject
matter hereof.  No representations, inducements, promises or agreements, oral or written, have been made by Landlord or Tenant, or anyone acting on behalf
of  Landlord  or  Tenant,  which  are  not  contained  herein,  and  any  prior  agreements,  promises,  negotiations,  or  representations  are  superseded  by  this
Lease.  This Lease may not be amended except by an instrument in writing signed by both parties hereto.

35.

Severability.  If any clause or provision of this Lease is illegal, invalid or unenforceable under present or future Legal Requirements,
then and in that event, it is the intention of the parties hereto that the remainder of this Lease shall not be affected thereby.  It is also the intention of the parties
to this Lease that in lieu of each clause or provision of this Lease that is illegal, invalid or unenforceable, there be added, as a part of this Lease, a clause or
provision as similar in terms to such illegal, invalid or unenforceable clause or provision as may be possible and be legal, valid and enforceable.

36.

Brokers.    Tenant  and  Landlord  represent  and  warrant  to  each  other  that  they  have  dealt  with  no  broker,  agent  or  other  person  in
connection with this transaction and that no broker, agent or other person brought about this transaction, other than the broker(s), if any, set forth in the Basic
Lease Provisions above, and each party agrees to indemnify and hold the other party harmless from and against any claims by any other broker, agent or other
person  claiming  a  commission  or  other  form  of  compensation  by  virtue  of  having  dealt  with  the  indemnifying  party  with  regard  to  this  leasing
transaction.  Landlord shall be responsible for the payment of a commission to Broker in connection with this Lease pursuant to the terms and conditions of a
separate written agreement with Landlord.

(e)

At Landlord's request from time to time, if Tenant's financial statements are not publicly available, Tenant shall furnish
Landlord with true and complete copies of its most recent annual and quarterly financial statements prepared by Tenant or Tenant's accountants.  Such annual
statements  shall  be  audited  by  an  independent  certified  public  accountant,  if  such  is  the  normal  practice  of  Tenant,  at  Tenant's  sole  cost  and
expense.  Landlord shall hold such financial statements and information in confidence, and shall not disclose the same except: (1) to Landlord's lenders or
potential lenders, (2) to potential purchasers of all or a portion of the Project, (3) to affiliates, employees, attorneys, accountants, consultants or other advisors,

amount of any interest payable on or in connection with this Lease.  If applicable law is ever judicially interpreted so as to render usurious any interest called

excess amounts theretofore collected by a party hereunder be credited on the applicable obligation (or, if the obligation has been or would thereby be paid in
full, refunded to the other party), and the provisions of this Lease immediately shall be deemed reformed and the amounts thereafter collectible hereunder
reduced, without the necessity of the execution of any new document, so as to comply with the applicable law, but so as to permit the recovery of the fullest

deemed merged into the judgment.

Telecommunications  Services  or  any  equipment  or  facilities  relating  thereto.    Tenant,  at  its  cost  and  for  its  own  account,  shall  be  solely  responsible  for
obtaining  all  Telecommunications  Services.    Tenant  shall  be  fully  responsible  for  any  damage  to  the  Building  and/or  the  Project  caused  by  any  of  the
telecommunications companies providing Telecommunications Services to Tenant and/or the Building.  Notwithstanding anything to the contrary set forth in
this Paragraph, neither the Telecommunications Services, nor any work or act in connection with the Telecommunications Services, by or on behalf of Tenant,
may invalidate or otherwise adversely affect any warranty relating to the Building and/or the Project; provided that upon receipt of Tenant's written request,
Landlord  shall  notify  Tenant  in  writing  of  such  warranty  (and  the  terms  thereof)  for  which  Tenant  shall  responsible  for  protecting  as  part  of  the

which may arise at any time under this Lease, or any obligation or liability which may be incurred by Landlord pursuant to any other instrument, transaction,

Option  to  Extend.    Landlord  hereby  grants  to  Tenant  two  (2)  consecutive  options  to  extend  the  Lease  Term  with  respect  to  the
Premises (each, an "Option"), the first Option shall be for a period of ten (10) years and the second Option shall be for a period of ten (10) years (each such
period,  an  "Option  Term")  commencing  upon  the  expiration  of  the  then  initial  Lease  Term,  upon  each  of  the  following  conditions  and
terms.  Notwithstanding the foregoing, Tenant may elect to split the second 10-year Option Term into two (2) five (5) year Option Terms, which election
Tenant must make (if at all) concurrently with Tenant's delivery of the Option Notice (defined below) for the second Option.  If Tenant timely makes such
election, then Tenant must exercise the Option to further extend the Lease Term for the third (and final) Option Term (if at all) in accordance with the terms
and  conditions  contained  in  this  Paragraph  41,  and  such  third  (and  final)  Option  Term  shall  be  subject  to  all  of  the  terms  and  condition  contained  in  this
Paragraph 41.

(a)

Tenant shall give to Landlord, and Landlord shall actually receive, on a date which is at least two hundred seventy (270)
days and not more than three hundred sixty-five (365) days prior to the then scheduled expiration date of the Lease Term, a written notice of Tenant's exercise
of an Option (an "Option Notice"),  time  being  of  the  essence.    If  an  Option  Notice  is  not  timely  so  given  and  received,  the  Option,  and  any  subsequent
Option (if any), shall automatically expire.

(b)

Tenant shall have no right to exercise an Option, notwithstanding any provision hereof to the contrary, if Tenant is then in

inability to exercise the Option because of the provisions of Paragraph 41(b) above.

(c)

The  period  of  time  within  which  an  Option  may  be  exercised  shall  not  be  extended  or  enlarged  by  reason  of  Tenant's

(d)

The Options granted to Tenant are personal to the Tenant originally named on this Lease (the "Original Tenant") or any
Tenant Affiliate to whom this Lease has been assigned or any other assignee approved in advance by Landlord pursuant to the terms of Paragraph 17 above
(but only if such other assignee has a tangible net worth of at least One Hundred Million Dollars [$100,000,000.00] in Current Dollars at the time of the
Transfer,  as  evidenced  by  financial  statements  reviewed  and  approved  in  advance  by  Landlord,  which  approval  shall  not  be  unreasonably  withheld,

(f)

All  of  the  terms  and  conditions  of  this  Lease  except  where  specifically  modified  by  this  Paragraph 41 or  as  otherwise
stated to be applicable only to the initial Lease Term shall apply during any Option Term, except for any provisions that were meant to be one-time Landlord
concessions including without limitation free rent, allowances and Landlord Work.  If Tenant exercises its right to extend the term of the Lease for an Option
Term pursuant to this Paragraph 41, the term "Lease Term" or "Term"  as  used  in  the  Lease,  shall  be  construed  to  include  the  initial  Lease  Term  and  the
applicable Option Term (except with respect to any provisions expressly modified by this Paragraph 41 or otherwise stated as being applicable only to the
initial Lease Term or any prior portion of the Lease Term).  

(g)

Effective on the first day of an Option Term, the Base Rent shall be equal to one hundred percent (100%) of then current
fair  market  rent  for  the  Premises  as  of  the  beginning  of  the  Option  Term  (the  "Fair  Market  Rent"),  taking  into  account  the  size,  age  and  quality  of  the
Premises (but not considering the value of the Tenant Improvements installed in the Premises by Tenant with funds in excess of the Tenant Improvement
Allowance  or  any  other  improvements  constructed  with  Tenant’s  funds),  the  submarket  where  the  Premises  are  situated,  the  acreage  of  the  Project,  the
parking, the clear height of the Premises, the length of the Option Term and all other relevant factors (including, without limitation, any concessions contained
within this Lease) and the creditworthiness of Tenant.  Fair Market Rent shall reflect all monetary and non-monetary concessions being granted to tenants for
comparable renewal transactions in the same submarket where the Premises are situated, including without limitation, improvements performed by landlords
and tenant improvements allowances, moving allowances, and rent concessions. Landlord shall notify Tenant of its determination of the Fair Market Rent for
the  applicable  Option  Term  (consistent  with  the  methodology  reflected  in  the  definition  above)  within  thirty  (30)  days  following  its  receipt  of  an  Option
Notice.  Such  Fair  Market  Rent,  as  set  forth  in  Landlord's  notice  to  Tenant,  shall  be  binding  upon  the  parties  unless  Tenant  provides  written  notice  of  its
disagreement within thirty (30) days following its receipt thereof.

(h)

If Tenant disagrees with Landlord's determination of the Fair Market Rent for the Option Term, Landlord and Tenant shall
confer for a period of thirty (30) days in an attempt to agree on the Fair Market Rent.  In the event Landlord and Tenant fail to reach an agreement on the Fair
Market  Rent  within  such  thirty  (30)  day  period,  then  the  Fair  Market  Rent  for  the  applicable  Option  Term  shall  be  determined  in  accordance  with  the
following  procedure  (the  "Arbitration  Procedure"),  which  Arbitration  Procedure  shall  be  binding  upon  the  parties:    Within  fifteen  (15)  days  after  the
expiration  of  the  thirty  (30)  day  period  described  above,  Landlord  and  Tenant  shall  each  select  a  licensed  real  estate  broker  with  at  least  ten  (10)  years'
experience in the R&D submarket where the Premises are situated.  If the two brokers are unable to agree within ten (10) days after their selection, they shall
select  a  similarly  qualified  third  broker  (the  "Neutral  Broker").    Within  twenty  (20)  days  after  selection  of  the  Neutral  Broker,  the  three  brokers  shall
simultaneously exchange determinations of the Fair Market Rent.  If the lowest determination of Fair Market Rent is not less than ninety-seven and one-half
percent  (97.5%)  of  the  highest  determination,  then  the  three  determinations  shall  be  averaged  and  the  result  shall  be  the  Fair  Market  Rent.  If  the  lowest
determination is less than ninety-seven and one-half percent (97.5%) of the highest determination, then the Fair Market Rent shall be deemed the rate set forth
in the determination submitted by a broker appointed by a party that is closest in dollar amount to the determination submitted by the Neutral Broker.  Each
party shall pay the cost of its own broker and the parties shall share the cost of the Neutral Broker equally.  If the Base Rent for an Option Term has not been
determined by the commencement date of the Option Term, then until such Base Rent is determined, Tenant shall pay Base Rent to Landlord at the rate in
effect immediately preceding the Option Term.  If the actual Base Rent for the Option Term is determined to be higher, then within fifteen (15) days after the
determination of such higher Base Rent, Tenant shall pay to Landlord the difference for each month of the Option Term for which Base Rent has already
become due.  If the actual Base Rent for the Option Term is determined to be lower, then within fifteen (15) days after the determination of such lower Base
Rent, Tenant shall receive a credit against Base Rent next due and owing in an amount equal to the difference between the actual Base Rent determined for
the Option Term and the amount for which Tenant has already paid during the Option Term.  Tenant shall continue to pay Landlord as set forth in the Lease
for  Operating  Expenses  during  the  applicable  Option  Term.  If  Tenant  was  obligated  to  pay  any  amortized  amounts  under  the  Lease  prior  to  the
commencement  of  the  applicable  Option  Term  and  there  remains  useful  life  with  respect  to  the  applicable  capital  improvement,  then  Tenant  shall  remain
obligated during the applicable Option Term to pay such amortized amounts in addition to the Base Rent (as adjusted to Fair Market Rent) and other amounts
payable under the Lease.

42.

Confidentiality.  Neither Landlord nor Tenant shall issue any press release or statement with regard to the terms and provisions of
this Lease without the consent of the other, nor shall either party disclose to any third party (other than its respective employees, directors, officers, agents,
attorneys,  consultants,  potential  and  actual  lenders,  potential  and  actual  purchasers,  potential  and  actual  insurers,  potential  and  actual  assignees  and
subtenants, members, investors and partners of such party), any information with respect to the financial terms and/or provisions of this Lease, except: (a) to
the extent necessary to comply with Legal Requirements, Private Restrictions, or a valid

1111154v7

41

 
 
 
 
court order of a court with competent jurisdiction, in which event the party making such disclosure shall so notify the other party as promptly as is practicable
(if possible, prior to making such disclosure) and shall endeavor to seek confidential treatment of such information; (b) to the extent necessary to comply with
the disclosure requirements of the S.E.C., the New York Stock Exchange, or similar entities, or in connection with other S.E.C. filings as customarily made by
publicly  traded  REIT  entities;  (c)  to  its  parent,  subsidiary  or  other  affiliated  companies,  their  banks,  auditors  and  attorneys  and  similar  professionals
(collectively, its "Permitted Recipients"), provided that the disclosing party shall be liable to the other party in the event that any of its Permitted Recipients
disclose any information that the disclosing party would be prohibited from disclosing pursuant to this Paragraph 42; (d) in order to enforce its rights pursuant
to  this  Lease;  (e)  to  a  bona  fide  prospective  or  an  actual  buyer  or  financier  as  well  as  the  Permitted  Recipients  thereof,  provided  that  any  such  buyer  or
financier first executes a commercially reasonable written confidentiality agreement pursuant to which they/it agree(s) to be bound by the provisions of this
paragraph or a similar undertaking of confidentiality, (f) for disclosure of square footage, length of term and charges or rents on earnings calls at investor
meetings as customarily disclosed by publicly traded REIT entities, or (g) to a prospective assignee or subtenant.  The terms of the first public statement made
regarding the Lease shall be reasonably and mutually agreed upon by Landlord and Tenant.  Notwithstanding anything to the contrary set forth herein, the
obligations of confidentiality contained herein, as they relate to a transaction, shall not apply to the "tax structure" or "tax treatment" of a transaction (as these
terms  are  used  in  Section  1.6011-4(b)(3)  (or  any  successor  provision)  of  the  Treasury  Regulations  (the  "Confidentiality Regulation")  promulgated  under
Section 6011 of the Internal Revenue Code of 1986, as amended), and each party (and any related party of such party) may disclose to any and all persons,
without limitation of any kind, the "tax structure" and "tax treatment" of a transaction (as these terms are defined in the Confidentiality Regulation).  Landlord
agrees  that  Tenant's  existing  trademarks  and  other  intellectual  property  (including  without  limitation  Tenant's  name/logo)  and  the  goodwill  associated
therewith are the sole and exclusive property of Tenant and may not be used by Landlord for any purpose, except with the express prior written consent of
Tenant.  Any breach of this Paragraph by a party shall entitle the other party, as its sole and exclusive remedy, to injunctive relief to restrain any threatened or
continued breach of this Paragraph without the requirement of posting a bond or other security.

43.

Design Review Committee(s) and Owners Association(s). If Landlord is a member of any design review committees and/or owners
associations,  then  (i)  if  the  Private  Restrictions  grant  the  design  review  committee  and/or  owners  association  more  discretion  than  granted  to  Landlord
hereunder, then Landlord shall not withhold its consent thereunder except as otherwise permitted hereunder, and (ii) if Landlord approves of any Tenant-Made
Alterations  hereunder  or  the  Tenant-Made  Alterations  are  Permitted  Alterations,  then  Landlord  shall  vote  in  favor  thereof  if  the  subject  Tenant-Made
Alterations are in fact in compliance with the Private Restrictions.  

44.

Landlord Lien Waiver.  Landlord agrees that Tenant shall have the right to pledge Tenant's furniture, Trade Fixtures, equipment or
other personal property owned by Tenant, located in the Premises and paid for without any funds contributed by Landlord (including the Tenant Improvement
Allowance) (the "Collateral") as security for Tenant's credit lines or other financing.  Landlord will agree to waive any statutory lien rights Landlord may
have or claim upon such Collateral to the extent such lien(s) arise solely out of the landlord-tenant relationship or the mere fact that such Collateral is located
within the Premises.  In the interest of clarity, such waiver shall not limit or impact Landlord's right to any judgment liens that may arise in favor of Landlord.
Provided that Tenant is not then in default under this Lease, upon written request of Tenant (but not more frequently than once in any twelve (12) month
period), Landlord shall provide its standard form of lien subordination agreement to be executed by Landlord, Tenant and any secured lender of Tenant with a
security  interest  in  the  Collateral  located  within  the  Premises  (which  form  shall  be  subject  modification  to  accommodate  any  commercially  reasonable
modifications negotiated by and among Landlord, Tenant and such secured lender).

45.

Landlord's Notice of Intent to Sell.  If Landlord intends to sell the Building to any unaffiliated third party during the Lease Term on
a stand-alone basis (i.e., not as part of a sale of the Project or any other property or building(s) whatsoever), then, prior to entering into a listing agreement
with a broker for the sale of the Building and otherwise entering into a purchase and sale agreement for such sale with any third party, Landlord shall deliver
written notice to Tenant specifying that Landlord intends to sell the Building on a stand-alone basis. For avoidance of doubt, (i) Tenant shall have no right to
receive any such notice if Landlord elects to sell the Building to an affiliate of Landlord or as part of a transaction involving any other property in addition to
the Building, including, without limitation, the sale of one or more properties in Landlord's and/or Landlord's affiliate's portfolio (even though such sale or
transfer includes the Building), (ii) this provision is not (nor shall it be interpreted as granting) an option to purchase, a right of first offer, a right of first
refusal, or any other similar right (it being acknowledged and agreed that this provision simply requires Landlord to provide Tenant with a written notice of
Landlord's intent to sell the Building on a stand-alone basis).

the expiration or earlier termination of the Lease Term), at Tenant's sole cost and expense, subject to the provisions of this Lease, install one (1) back-up
generator  (the  "Generator"),  at  a  location  to  be  mutually  agreed  upon  by  the  parties  (and  pursuant  to  plans  and  specifications  approved  in  advance  by

Generator.    Tenant  shall  deliver  to  Landlord  full  and  complete  plans  and  specifications  with  respect  to  the  Generator,  which  shall  be  subject  to  the  prior
written approval of Landlord, such approval not to be unreasonably withheld, conditioned or delayed.  Landlord's review of such plans and specifications
shall  be  for  its  own  benefit  only,  and  Landlord  shall  have  no  liability  to  Tenant  in  connection  with  such  review.    Tenant  shall  ensure  that  the  Generator
complies  at  all  times  with  Landlord's  commercially  reasonable  rules  and  regulations  that  Tenant  has  received  written  notice  of,  and  with  all  Legal

a "Tenant-Made Alteration" under this Lease (and shall accordingly be subject to all of the terms of Paragraph 12 of this Lease, except that Tenant shall be
required to remove the Generator on or before the expiration or earlier termination of the Lease Term, and Tenant, at its sole expense, shall repair any and all
damage caused by such removal on or before the expiration or earlier termination of the Lease Term).  Without limiting the foregoing, Landlord shall have the
right, at any time in the case of emergency and upon reasonable prior notice and affording Tenant an opportunity to have a representative present at other

with respect to any and all Claims arising out of or in connection with the Generator, and Tenant shall repair all damage to the Premises, the Building and the
Project contained therein arising in connection with the Generator. Tenant's indemnification obligation pursuant to this paragraph shall survive the expiration
or earlier termination of this Lease.  Additionally, except to the extent resulting from Landlord's negligence or willful misconduct but subject to the waiver of
subrogation set forth above, Landlord shall have no liability whatsoever in connection with the Generator, and Tenant shall look to its insurance in connection
with  any  claims  or  losses  suffered  in  connection  with  the  Generator.   The  presence  and  use  of  the  Generator  shall  otherwise  be  subject  to  all  of  Tenant's
obligations, liabilities and restrictions set forth in this Lease.

affected by any penetration.  All work done in connection with any permitted roof penetration shall be performed by Landlord or Landlord's agent at Tenant's
sole cost and expense.  The installation of the Rooftop Equipment shall not damage the Building or existing structures thereon.  Landlord may obtain the
services of a structural engineer to design any additional supports required to support the Rooftop Equipment, and to monitor the installation thereof, and
Tenant

1111154v7

44

 
 
 
 
shall reimburse Landlord, within ten (10) business days after receipt by Tenant of an invoice, and Tenant's receipt of reasonable supporting documentation, for
Landlord's actual and reasonable out-of-pocket cost of such services and such supports.  The Rooftop Equipment shall remain the personal property of Tenant
and shall be removed by Tenant prior to the expiration or earlier termination of this Lease, and Tenant shall repair any damage caused by the removal of the
Rooftop Equipment and its associated wiring, cables and other components and immediately, at Tenant's sole cost and expense, restore the Rooftop Premises
to the condition which existed prior to the installation of the Rooftop Equipment.

(e)

Tenant may, at Tenant's own cost and expense, upon reasonable prior written notice to Landlord (except in the event of an
emergency, in which case only such notice as is reasonable under the circumstances), access the Rooftop Premises to repair, replace, reorient or remove the
Rooftop Equipment, or replace it with generally similar equipment, provided that (i) any new equipment can be properly accommodated on Rooftop Premises
without placing materially greater demands upon the electrical, mechanical, structural, life safety or other building systems of the Building than the original
Rooftop  Equipment;  (ii)  Tenant  at  its  cost  shall  restore  the  affected  portion  of  Rooftop  Premises  to  the  condition  in  which  it  was  prior  to  such  repair,
reorientation,  removal  or  replacement,  and  all  of  such  repair,  reorientation,  removal  or  replacement  shall  be  performed  in  accordance  with  Landlord's  and
industry standard engineering practices and by contractors or other persons reasonably approved by Landlord; and (iii) all plans and designs of Tenant relating
to  such  repair,  reorientation,  removal  or  replacement  shall  in  any  case  be  subject  to  the  prior  written  approval  of  Landlord,  which  approval  shall  not  be
unreasonably withheld, conditioned or delayed.

Subject to Landlord's Construction Warranty, Tenant hereby agrees that the Rooftop Premises shall be taken "as is", "with
all  faults",  without  any  representations  and  warranties,  and  Tenant  hereby  agrees  and  warrants  that  it  has  investigated  and  inspected  the  condition  of  the
Rooftop Premises and the suitability of same for Tenant's purposes.  

(f)

(g)

Tenant,  at  Tenant's  sole  cost  and  expense,  will,  at  all  times  in  connection  with  the  installation,  use,  operation  and
maintenance  of  the  Rooftop  Equipment,  comply  with  all  Legal  Requirements  and  Private  Restrictions  affecting  the  installation,  use,  operation  and
maintenance of the Rooftop Equipment, including, without limitation, applicable building and fire codes, and will comply with all requirements of the Federal
Aviation Administration and Federal Communications Commission in respect thereof. Tenant, at Tenant's sole cost and expense, shall be obligated to secure
and obtain and provide Landlord with copies of all required permits, approvals and licenses for or with respect to the installation or operation of the Rooftop
Equipment prior to the commencement of any installation activities hereunder, and Tenant shall be obligated to keep in full force and effect and renew, as
applicable, all required permits, approvals and licenses required hereunder.

TENANT WORK LETTER

This  Tenant  Work  Letter  shall  set  forth  the  terms  and  conditions  relating  to  the  construction  of  the  Premises.    This  Tenant  Work  Letter  is
essentially  organized  chronologically  and  addresses  the  issues  of  the  construction  of  the  Premises,  in  sequence,  as  such  issues  will  arise  during  the  actual
construction  of  the  Premises.    All  references  in  this  Tenant  Work  Letter  to  Articles  or  Paragraphs  of  "this  Lease"  shall  mean  the  relevant  portions  of
Paragraphs 1 through 47 of this Lease to which this Tenant Work Letter is attached as Exhibit B, and all references in this Tenant Work Letter to Sections of
"this Tenant Work Letter" shall mean the relevant portions of Sections 1 through 5 of this Tenant Work Letter.

SECTION 1

LANDLORD WORK; DELIVERY OF THE PREMISES AND BASE BUILDING; LANDLORD'S CONSTRUCTION WARRANTY

1.1

Landlord  Work.  Landlord  shall,  on  a  one-time  basis  only,  using  Project-standard  quantities,  specifications  and  materials  (unless
otherwise expressly specified herein), construct the Building and perform work within the Project as detailed in the specifications described in Schedule  1
attached to this Exhibit B (the "Base Building Specifications"). The improvements and work described in such Base Building Specifications may be referred
to  herein  as  the  "Landlord Work".    Except  as  set  forth  in  the  Base  Building  Specifications,  the  exact  scope  and  specifications  for  each  element  of  the
Landlord Work will be determined by Landlord. Landlord shall not make any material changes to the Base Building Specifications unless either (a) Landlord
has obtained the approval of Tenant to such change (such approval not to be unreasonably withheld, conditioned or delayed), or (b) Landlord is required to do
so  pursuant  to  Legal  Requirements,  the  Private  Restrictions  or  by  applicable  governmental  authorities,  in  which  case  no  consent  of  Tenant  shall  be
required.  Tenant shall not be permitted to make any changes or modifications to the Landlord Work and/or the Base Building Specifications without the prior
written consent of Landlord, which consent may be withheld in Landlord's sole discretion if such change or modification would result in any of the following:
(i) a delay in Substantial Completion of the Landlord Work, unless Tenant agrees that any such delay shall constitute a Tenant Delay (as hereafter defined);
(ii)  an  increase  in  the  cost  of  designing  or  constructing  any  of  the  Landlord  Work,  unless  Tenant  agrees  to  pay  for  such  increased  cost  in  the  form  of  a
deduction from the Tenant Improvement Allowance (or if insufficient proceeds from the Tenant Improvement Allowance remain, then Tenant shall pay for
such increased cost within thirty (30) days of receipt of an invoice from Landlord); (iii) a material lowering or degradation of the quality of the Landlord
Work  set  forth  in  the  Base  Building  Specifications;  (iv)  a  reduction  in  the  square  footage  of  the  Premises  from  the  square  footage  set  forth  in  the  Base
Building Specifications; and/or (v) a violation of any Legal Requirements and/or the Private Restrictions.  In the event Tenant desires to change the Landlord
Work (or proposes a change to the Landlord Work that either modifies the scope or the specifications from the scope or specifications set forth in the Base
Building Specifications), then Tenant shall deliver written notice (the "Drawing Change Notice") of the same to Landlord, setting forth in reasonable detail
the changes (the "Tenant Change") (including a written narrative) that Tenant desires to make to the Landlord Work.  Landlord shall, in writing, within ten
(10)  business  days  (or  such  longer  period  of  time  as  is  reasonably  necessary,  including,  without  limitation,  in  order  to  obtain  the  written  approval  of  any
applicable  design  review  committee[s]  and/or  owners  association[s])  of  receipt  of  a  Drawing  Change  Notice  either  (i)  approve  the  Tenant  Change,  or  (ii)
disapprove the Tenant Change and deliver a written notice to Tenant specifying in reasonably sufficient detail the reasons for Landlord's disapproval.  For
each Tenant Change requested, Landlord shall, at the same time as Landlord's approval notice for such Tenant Change, submit to Tenant for Tenant's approval
a cost estimate and the amount of Tenant Delay for each Tenant Change, which Tenant shall either approve or disapprove within five (5) business days of
receipt from Landlord.  Landlord shall not be obligated to proceed with any Tenant Change without written authorization to do so from Tenant. Except as
provided  below,  and  subject  to  the  terms  of  Section  12(d)  of  the  Lease  regarding  Improvements  Not  Subject  to  Restoration,  Landlord  shall  notify  Tenant
whether Tenant shall be required to remove a particular Tenant Change at the expiration of earlier termination of the Lease, or whether such Tenant Change
shall remain on the Premises.  Notwithstanding the foregoing, Tenant shall have the right, at the time it submits a Drawing Change Notice to Landlord, to
make a written request that Landlord notify Tenant whether Tenant shall be required to remove the applicable Tenant Change at the expiration or termination
of the Lease Term, in which event Tenant shall only be obligated to remove (i) those Tenant Changes that Landlord notified Tenant in writing at the time
Landlord provides

1111154v7

Exhibit B—Page 1

 
 
 
 
its consent that it must remove at the end of the Lease Term, and (ii) those Tenant Changes that Tenant did not timely seek or did not obtain Landlord's written
consent to leave in place at the end of the Lease Term, and that Landlord ultimately requires Tenant to remove.  Failure of Landlord to notify Tenant at the
time that Landlord issues its consent that a Tenant Change must be removed shall mean that Tenant shall be obligated to remove the Tenant Change unless
Landlord ultimately agrees in writing to permit the Tenant Change to remain on the Premises at the expiration or earlier termination of the Lease. Any Tenant
Change(s) which Landlord has elected to not require Tenant to remove shall remain on the Premises as Landlord's property and shall be deemed abandoned
by  Tenant  at  the  expiration  or  earlier  termination  of  the  Lease;  provided,  however,  that  Tenant  shall  have  the  right  to  remove  such  Tenant  Change(s)  in
connection with future Alterations to the Premises made in accordance with the terms and conditions of the Lease. Notwithstanding anything to the contrary
contained in this Tenant Work Letter, Tenant hereby acknowledges and agrees that Landlord shall not be obligated to delay the performance of any of the
Landlord Work  even  if  there  is  a  proposed  Tenant  Change  that  might  alter  the  Landlord Work  unless  and  until  such  time  as  there  is  an  approved  Tenant
Change or Tenant otherwise requests in writing for Landlord to delay performance of the Landlord Work in order to evaluate a potential Tenant Change (in
which case any delay resulting therefrom shall constitute a Tenant Delay).

1.2

Substantial  Completion.  Upon  Substantial  Completion  of  the  Landlord  Work,  Landlord  shall  deliver  the  Premises  and  "Base
Building",  as  that  term  is  defined  below,  to  Tenant,  and  Tenant  shall  accept  the  Premises  and  Base  Building  from  Landlord  in  their  then  existing  "as-is"
condition, subject to the terms and condition contained in the Lease and Landlord's Construction Warranty (defined below). The "Base Building" shall consist
of  those  portions  of  the  Premises  which  were  in  existence  prior  to  the  construction  of  the  Tenant  Improvements  in  the  Premises  (including  the  Landlord
Work).  Landlord's  contractor  shall  be  designated  and  retained  by  Landlord  to  construct  the  Landlord  Work.  For  purposes  of  this  Lease,  "Substantial
Completion"  of  the  Landlord  Work  in  the  Premises  shall  occur  upon  the  completion  of  construction  of  all  of  the  Landlord  Work  in  the  Premises  in
accordance  with  the  Base  Building  Specifications  and  all  applicable  Legal  Requirements  and  Private  Restrictions  in  effect  as  of  the  date  of  Substantial
Completion (as the same shall be certified by Landlord's architect to Landlord and Tenant) and Landlord’s receipt of all required sign-offs directly related to
the Landlord Work by applicable governmental authorities with jurisdiction over the Project, with the exception of any Punch List Items that do not materially
impair Tenant from commencing construction of the Tenant Improvements, the Tenant Improvements and any tenant fixtures, work-stations, built-in furniture
or equipment to be installed by Tenant. Notwithstanding the foregoing, in the event that a sign-off by a governmental authority cannot be obtained as a result
of  Tenant's  particular  use  of  the  Premises  or  any  additional  work  to  be  performed  by  or  on  behalf  of  Tenant  outside  of  the  scope  of  the  Landlord  Work
(including, without limitation, the installation of any of the Tenant Improvements and/or Tenant's trade fixtures or equipment), then the receipt of such sign-
offs by the applicable governmental authority shall not be required for Substantial Completion of the Landlord Work to occur (and only the certification by
Landlord's architect shall be required).   In the event of any dispute between Landlord and Tenant as to whether Substantial Completion of the Landlord Work
has occurred, the sign-off and approval of the Landlord Work by the municipal building inspector shall be conclusive. Within ten (10) business days after
Substantial  Completion  of  the  Landlord  Work  (as  reasonably  determined  by  Landlord),  Tenant  and  Landlord  shall  jointly  conduct  a  walk-through  of  the
Premises and shall jointly prepare a punch list ("Punch List") of items needing additional work ("Punch List Items"); provided, however, the Punch List
shall be limited to items which are required by the Base Building Specifications and any other changes mutually agreed to in writing by the parties.  Landlord
agrees to repair the Punch List Items promptly following the joint walk through but, in no event, later than thirty (30) days thereafter; provided, however, if
any item on the Punch List cannot reasonably be corrected or remedied within such 30-day period, then Landlord shall have such additional time as shall be
reasonably necessary to correct or remedy such item; provided, further, that the Punch List shall have no effect on Substantial Completion.  If Landlord and
Tenant are unable to conduct such walk-through within such ten (10) business day period due to scheduling conflicts, then the parties shall conduct the walk-
through as soon as reasonably practical; provided, however, in no event shall the date of Substantial Completion and/or the Commencement Date be impacted
to accommodate such walk-through.

1.3

Delay of the Substantial Completion of the Premises.  Except as provided in this Section 1.3, the Commencement Date and Tenant's
obligation  to  pay  rent  for  the  Premises  shall  occur  as  set  forth  in  the  Lease.    However,  if  there  shall  be  a  delay  or  there  are  delays  in  the  Substantial
Completion of the Landlord Work in the Premises as a result of the following (collectively, "Tenant Delays"):

1111154v7

Exhibit B—Page 2

 
 
 
 
 
Tenant Party within the express time periods required herein;

1.3.1

Tenant's failure to approve or disapprove any matter requiring Tenant's approval or any other delay by Tenant or any

periods;

1.3.2

A breach by Tenant of the terms of this Tenant Work Letter or the Lease not cured within the applicable notice and cure

1.3.3

1.3.4

1.3.5

Any delay caused by a Tenant Change;

Any matter expressly described in the Lease and/or this Tenant Work Letter as constituting a Tenant Delay; or

Any other acts or omissions of Tenant and/or any Tenant Party that interferes with by Tenant and/or any Tenant Party

with the construction of the Landlord Work,

then, notwithstanding anything to the contrary set forth in the Lease or this Tenant Work Letter and regardless of the actual date of the Substantial
Completion of the Landlord Work in the Premises, the date of Substantial Completion thereof shall be deemed to be the date that Substantial Completion
would have occurred if no Tenant Delay or Delays, as set forth above, had occurred; provided, however, that with respect to any delay under clause 1.3.2 or
1.3.5 no Tenant Delay shall have occurred unless and until Landlord has provided Tenant's Representative (as defined below) with email notice specifying
that a Tenant Delay may result from Tenant's continued actions or failure to act, and Tenant does not cease or complete (as the case may be) such actions
within one (1) business day after receipt of such email notice.  With respect to other delays under clauses 1.3.1, 1.3.3, and/or 1.3.4, Landlord shall provide
Tenant's Representative with email notice within ten (10) days following the date Landlord actually becomes aware of the delay; provided, however, there
shall  be  no  cure  period  with  respect  to  such  delays  and  the  Tenant  Delay  shall  be  deemed  to  have  occurred  (and  started  accruing)  on  date  set  forth  in
Landlord's notice specifying the actual day that the Tenant Delay occurred.

1.4

Landlord shall make available to Tenant the benefit of any warranties and guaranties by Landlord's contractor and material providers
to the extent relating to the Landlord Work.  The contractor shall be designated and retained by Landlord to construct the Landlord Work.  Except as expressly
set  forth  in  this  Section  1.4,  Landlord  does  not  warrant  that  the  Landlord  Work  or  any  component  thereof  shall  be  free  of  defects  or  shall  not  require
maintenance and/or repair within any particular period of time (and, except as expressly set forth in this Section 1.4, Tenant hereby waives all claims against
Landlord relating to, or arising out of the construction of, the Landlord Work; provided, however, that nothing contained herein shall limit Landlord's express
obligations under the Lease including, without limitation, its repair and maintenance obligations).  Subject to the terms and conditions of this Section 1.4, for
a  period  of  one  (1)  year  following  Substantial  Completion  of  the  Landlord  Work  ("Landlord's  Construction  Warranty"),  Landlord  warrants  that  the
Landlord Work will be, (i) free from material defects in workmanship and materials, and (ii) performed in compliance with applicable Legal Requirements
and Private Restrictions in effect as of the date the building permit was issued to commence construction of the Landlord Work (but without regard to any
Legal Requirements and/or Private Restrictions triggered by any Tenant Improvements, Tenant-Made Alterations or other improvements performed by or on
behalf  of  Tenant,  or  any  particular  use  of  the  Premises  by  Tenant  (as  opposed  to  Legal  Requirements  and  Private  Restrictions  applicable  generally  to
office/industrial/warehouse buildings in the market area) or the installation of any furniture, fixtures or equipment by Tenant, Tenant hereby acknowledging
that  all  Legal  Requirements  and/or  Private  Restrictions  triggered  by  the  same  being  Tenant's  sole  responsibility).    If  there  is  a  breach  of  Landlord's
Construction Warranty, Landlord shall, following timely written notice from Tenant identifying such breach with reasonable specificity, as Tenant's sole and
exclusive remedy, perform the work as is reasonably necessary to cure such material breach in Landlord's Construction Warranty.  In connection with the
performance of any such warranty work, (a) subject to the terms and conditions of the Lease, Landlord shall have the right to enter upon the Premises and/or
into the Building at any time during normal business hours (except that Landlord may enter at any time, without notice, in case of an emergency) to perform
such work, and in no event shall the performance of such work by Landlord entitle Tenant to any abatement of rent or other compensation so long as Landlord
uses commercially reasonable efforts to minimize any material interference with Tenant's access to or use of the Premises and Project for Tenant's normal
business  operations  as  a  result  of  the  performance  of  any  such  work;  and  (b)  Tenant  shall  cooperate  with  Landlord  in  identifying  the  defect  in
question.  Notwithstanding the foregoing, Landlord's Construction Warranty shall not apply with respect to defects or damage arising due to work performed
by

1111154v7

Exhibit B—Page 3

 
 
 
 
 
 
 
 
Tenant (including, without limitation, the Tenant Improvements and/or any Tenant-Made Alterations) and/or the negligence or willful misconduct of Tenant
and/or any Tenant Party.  If Tenant does not deliver written notice to Landlord of any breach of Landlord's Construction Warranty on or before the one (1)
year anniversary of the date of Substantial Completion, then Tenant shall be deemed to have inspected and accepted the Premises in their present condition
and  Landlord  shall  have  no  further  obligation  to  correct  such  condition  under  this  Section  1.4,  but  rather  such  condition  shall  be  subject  to  the  repair,
maintenance and replacement obligations of Landlord and Tenant as expressly set forth in the Lease.

SECTION 2

TENANT IMPROVEMENTS

2.1

Tenant  Improvement  Allowance.    Tenant  shall  be  entitled  to  a  one-time  tenant  improvement  allowance  ("Tenant  Improvement
Allowance")  in  the  amount  of  up  to  Two  Million  Nine  Hundred  Forty-Seven  Thousand  Two  Hundred  Twenty-Five  Dollars  ($2,947,225.00)  (based  upon
$25.00 per square foot of the Premises) for the cost relating to the initial design and the actual cost of constructing Tenant's physical improvements which are
permanently affixed to the Premises ("Tenant Improvements").  Notwithstanding anything to the contrary contained in this Tenant Work Letter, in no event
shall  (i)  Landlord  be  obligated  to  make  disbursements  pursuant  to  this  Tenant  Work  Letter  in  a  total  amount  which  exceeds  the  Tenant  Improvement
Allowance, (ii) Tenant be entitled to any portion of the Tenant Improvement Allowance not requested by Tenant (in accordance with the terms and conditions
of this Work Letter) on or prior to the date that is twelve (12) months following the Commencement Date, and/or (iii) any portion of the Tenant Improvement

construction of a mezzanine within the Premises;

2.2.1.3

required  by  the  Construction  Drawings  (including  any  Tenant  Change),  such  cost  to  include  all  direct  architectural  and/or  engineering  fees  and  expenses
incurred  in  connection  therewith  (provided,  however,  in  no  event  shall  reimbursement  from  the  Tenant  Improvement  Allowance  for  the  cost[s]  of  such
changes exceed an aggregate amount equal to $3.75 for each square foot of space in the Premises);

2.2.1.4

the release of monies for the benefit of Tenant as follows.  

2.2.2

2.2.2.1

Monthly Disbursements. From time to time during the construction of the Tenant Improvements (but not
more than once per month), Tenant shall deliver to Landlord: (i) a request for payment of the "Contractor," as that term is defined in Section 4.1 of this Tenant
Work  Letter,  approved  by  Tenant,  in  a  form  to  be  provided  by  Landlord,  showing  the  schedule,  by  trade,  of  percentage  of  completion  of  the  Tenant
Improvements in the Premises, detailing the portion of the work completed and the portion not completed; (ii) invoices from all of "Tenant's Agents," as that
term is defined in Section 4.1.2 of this Tenant Work Letter, for labor rendered and materials delivered to the Premises; (iii) executed mechanic's lien releases
from all of Tenant's Agents in a form reasonably acceptable to Landlord; and (iv) all other information reasonably requested by Landlord.  Within thirty (30)
days following Tenant’s request, Landlord shall deliver a check to the Contractor (or to Tenant if Tenant provides Landlord proof of Tenant's payment to the
Contractor and unconditional lien waivers from the Contractor for the applicable portion of the Tenant Improvements completed), in payment of the lesser of:
(A) the amounts so requested by Tenant, as set forth in this Section 2.2.2.1, above, less a ten percent (10%) retention (the aggregate amount of such retentions
to be known as the "Final Retention"), and (B) the balance of any remaining available portion of the Tenant Improvement Allowance (not including the Final
Retention),  provided  that  Landlord  does  not  dispute  any  request  for  payment  based  on  a  non-compliance  of  any  work  with  the  "Approved  Working
Drawings," as that term is defined in Section 3.2 below, or due to any substandard work.  Landlord's payment of such amounts shall not be deemed Landlord's
approval or acceptance of the work furnished or materials supplied as set forth in Tenant's payment request.

2.2.2.2

Final Retention.  Subject  to  the  provisions  of  this  Tenant  Work  Letter,  a  check  for  the  Final  Retention
payable to the Contractor (or to Tenant if Tenant provides Landlord proof of Tenant's payment to the Contractor and final unconditional lien waivers from the
Contractor for all of the Tenant Improvements completed) shall be delivered by Landlord to Tenant within thirty (30) days following the later of: (I) the date
Tenant has completed the Tenant Improvements, (II) the Commencement Date, and (III) the date Landlord receives written notice from Tenant requesting
payment of the Tenant Improvement Allowance, provided that (i) Tenant delivers to Landlord final, unconditional lien waivers, in accordance with applicable
laws  (including,  without  limitation,  the  appropriate  provisions  of  California  Civil  Code  Sections  8132-8138),  from  Tenant's  general  contractor  and  all
subcontractors,  materialmen  and  suppliers  that  have  performed  work  or  supplied  materials  in  connection  with  the  Tenant  Improvements,  (ii)  no  Event  of
Default exists under the Lease, (iii) Landlord has determined that no substandard work exists which adversely affects the mechanical, electrical, plumbing,
heating, ventilating and air conditioning, life-safety or other systems of the Project, the structure or exterior appearance of the Project, or any other tenant's
use  of  such  other  tenant's  leased  premises  in  the  Project,  (iv)  Tenant  has  completed  all  of  the  Tenant  Improvements  in  substantial  conformity  with  the
Approved Working Drawings, all building permits issued in connection with the Tenant Improvements, all Legal Requirements, the Private Restrictions and
the terms and provisions of this Exhibit B, and (v) Tenant has delivered to Landlord the following: (a) a copy of a final or permanent (i.e. not temporary or
conditional)  certificate  of  occupancy  (or  local  equivalent)  for  the  entire  Premises  issued  by  the  appropriate  governmental  authority,  (b)  a  certificate  of
completion issued by Tenant's Architect or Tenant's Contractor, certifying that the Tenant Improvements have been completed in substantial conformity with
the Approved Working Drawings, and (d) copies of all applicable permits evidencing final approval and sign of the Tenant Improvements by the municipal
building  inspector(s).    Further,  within  thirty  (30)  days  following  the  conclusion  of  construction,  but  not  as  a  condition  to  the  payment  of  the  Tenant
Improvement Allowance, (1) Tenant shall cause the Contractor (A) to update the Approved Working Drawings as necessary to reflect all changes made to the
Approved Working Drawings during the course of construction, (B) to deliver to Landlord two (2) sets of such as-built drawings (in .PDF form), and (C) to
deliver to Landlord a computer disk containing the Approved Working Drawings in AutoCAD format and (2) Tenant shall deliver to Landlord a copy of all
warranties, guaranties, and operating manuals and information relating to the Tenant Improvements, equipment, and systems in the Premises.

2.2.2.3

Other Terms.    Landlord  shall  only  be  obligated  to  make  disbursements  from  the  Tenant  Improvement
Allowance to the extent costs are incurred by Tenant for Tenant Improvement Allowance Items.  All Tenant Improvement Allowance Items for which the
Tenant Improvement Allowance has been made available shall be deemed Landlord's property under the terms of this Lease; provided, however, Landlord
reserves the right to require Tenant to remove all or any portion of the Tenant Improvements at the expiration or earlier termination of the Lease. At the time
Landlord consents to the applicable Tenant Improvements,  Landlord  shall  notify  Tenant  whether  Tenant  shall  be  required  to  remove  the  applicable  Tenant
Improvement at  the  expiration  or  termination  of  the  Lease  Term,  and  to  restore  the  Premises  to  the  condition  required  under  Paragraph 21  of  the  Lease.
Failure  of  Landlord  to  notify  Tenant  at  the  time  that  Landlord  issues  its  consent  that  a  Tenant  Improvement  must  be  removed  shall  mean  that  Landlord
reserves the right to require Tenant to remove such items at the expiration or earlier termination of the Lease.  Notwithstanding the foregoing or anything to
the contrary contained herein, Landlord hereby agrees that Tenant shall not be required to remove the Tenant Improvements located in the northern office area
of the Premises as depicted on the site plan attached to the Lease as Exhibit F.   

2.3

Failure to Pay Tenant Improvement Allowance When Due. If Landlord fails to timely fulfill its obligation to fund any
portion of the Tenant Improvement Allowance in accordance with the provisions of this Work Letter, then Tenant shall be entitled to deliver written notice
(the "Payment Notice") to Landlord.  If Landlord still fails to fulfill any such obligation within thirty (30) days after Landlord's receipt of the Payment Notice
from Tenant and if Landlord fails to deliver notice to Tenant within such thirty (30) day period explaining Landlord's reasons that Landlord in good faith
believes that the amounts described in Tenant's Payment Notice are not due and payable by Landlord (the "Refusal Notice"), then Tenant shall be entitled to
offset the amount so owed to Tenant by Landlord but not paid by Landlord (or if Landlord delivers a Refusal Notice but only with respect to a portion of the
amount  set  forth  in  the  Payment  Notice  and  Landlord  fails  to  pay  such  undisputed  amount  as  required  by  then  next  succeeding  sentence,  the  undisputed
amount so owed to Tenant) against Tenant's next obligations to pay Base Rent.  Notwithstanding the foregoing, if Landlord delivers a Refusal Notice, then
notwithstanding anything to the contrary contained herein, Tenant shall have no right whatsoever to withhold or offset any portion of the amount set forth in
Tenant's Payment Notice, and Landlord shall pay to Tenant, concurrently with the delivery of the Refusal Notice, the undisputed portion of the amount set
forth in the Payment Notice.  However, if an Event of Default shall have occurred at the time that such offset would otherwise be applicable, Tenant shall not
be entitled to such offset until such Event of Default is cured.  If Landlord delivers a Refusal Notice, and if Landlord and Tenant are not able to agree on the
disputed  amounts  to  be  so  paid  by  Landlord,  if  any,  within  ten  (10)  days  after  Tenant's  receipt  of  a  Refusal  Notice,  Tenant  shall  have  no  right  to  offset
whatsoever, but Tenant may proceed to claim a default by Landlord under this Lease, and if elected by either Landlord or Tenant, the matter shall proceed to
resolution by appropriate legal proceedings. If Tenant prevails in the legal proceedings, the amount of the award may be deducted by Tenant from Base Rent
next due and owing under the Lease.  

SECTION 3

CONSTRUCTION DRAWINGS FOR TENANT IMPROVEMENTS

3.1

Selection of Architect/Construction Drawings.  Tenant shall retain an architect approved by Landlord (the "Architect") to prepare the
Construction Drawings.  CRB and Rios Clemente Hale Studios are hereby approved as Architect if selected by Tenant.  Tenant shall retain the engineering
consultants approved by Landlord (the "Engineers") to prepare all plans and engineering working drawings relating to the structural, mechanical, electrical,
plumbing, HVAC, life-safety, and sprinkler work in the Premises as related to the Tenant Improvements, which work is not part of the Base Building.  CRB
and KPW are hereby approved as Engineers if selected by Tenant.  The plans and drawings to be prepared by Architect and the Engineers hereunder shall be
known collectively as the "Construction Drawings".  Tenant and Architect shall verify, in the field, the dimensions and conditions as shown on the relevant
portions of the base building plans, and Tenant and Architect shall be solely responsible for the same, and Landlord shall have no responsibility in connection
therewith.  Landlord's review of the Construction Drawings as set forth in this Section 3, shall be for its sole purpose and shall not imply Landlord's review of
the  same,  or  obligate  Landlord  to  review  the  same,  for  quality,  design,  Code  compliance  or  other  like  matters.    Accordingly,  notwithstanding  that  any
Construction  Drawings  are  reviewed  by  Landlord  or  its  space  planner,  architect,  engineers  and  consultants,  and  notwithstanding  any  advice  or  assistance
which may be rendered to Tenant by Landlord or Landlord's space planner, architect, engineers, and consultants, Landlord shall have no liability whatsoever
in connection therewith and shall not be responsible for any omissions or errors contained in the Construction Drawings.  To the extent the same complies
with Legal Requirements and Private Restrictions, Landlord hereby approves the preliminary plans attached hereto as Schedule 2 to Exhibit B.  

1111154v7

Exhibit B—Page 6

 
 
 
 
3.2

Approved Working Drawings.  Landlord shall approve (or disapprove) the Construction Drawings prepared by the Architect within
ten (10) business days  after  Landlord  receives  the  same  (or  such  longer  period  of  time  as  is  reasonably  necessary  to  obtain  the  written  approval  of  any
applicable  design  review  committee[s]  and/or  owners  association[s])  (as  may  be  approved,  the  "Approved  Working  Drawings").    Landlord  shall  not
unreasonably withhold its consent to the Construction Drawings, except to the extent that anything depicted or described in the Construction Drawings could
reasonably  be  expected  to  adversely  impact  the  structure  and/or  structural  elements  of  the Building,  or  any  Building  systems,  in  which  event  Landlord's
consent shall be in its sole and absolute discretion, or the exterior appearance of the Project, Building, and/or Premises, in which event Landlord's consent
shall be in its sole and good faith discretion).  If Landlord fails to notify Tenant in writing of its approval or disapproval of the Construction Drawings within
ten (10) business days after Landlord receives the same, then Tenant may deliver a written notice to Landlord stating in the subject line in ALL CAPS that
"YOUR ATTENTION IS REQUIRED, IF LANDLORD FAILS TO RESPOND TO THE MATTERS DESCRIBED HEREIN WITHIN TEN (10) BUSINESS
DAYS FOLLOWING THE DATE OF THIS NOTICE, LANDLORD WILL BE DEEMED TO HAVE APPROVED THE CONSTRUCTION DRAWINGS
TO  THE  EXTENT  THE  PROPOSED  CONSTRUCTION  DRAWINGS  COMPLY  WITH  LEGAL  REQUIREMENTS  AND  THE  PRIVATE
RESTRICTIONS",  and  if  Landlord  fails  to  approve  or  disapprove  of  the  proposed  Construction  Drawings  within  ten (10) business  days  after  Landlord's
receipt of such written notice, then the proposed Construction Drawings shall be deemed approved by Landlord (but not any design review committee and/or
owners association) to the extent the same comply with Legal Requirements and the Private Restrictions. If Landlord disapproves (which disapproval shall be
in writing and shall specify in reasonable detail the basis of such disapproval) of the Construction Drawings, Tenant shall revise such Construction Drawings
within  ten  (10)  business  days  after  receipt  of  Landlord's  disapproval  and  resubmit  the  revised  Construction  Drawings  back  to  Landlord  for  Landlord's
review.  Thereafter, within ten (10) business days  following  receipt  of  same (or  such  longer  period  of  time  as  is  reasonably  necessary,  including,  without
limitation, in order to obtain the written approval of any applicable design review committee[s] and/or owners association[s]), Landlord will either approve or
disapprove the Construction Drawings.  This process shall be repeated until the Construction Drawings are ultimately approved by Landlord such that they
become Approved Working Drawings.  Once approved by Landlord (any applicable design review committee[s] and/or owners association[s]), Tenant shall
submit the Approved Working Drawings to the City of Newark, CA and diligently pursue its receipt of all applicable building permits.  Tenant hereby agrees
that neither Landlord nor Landlord's consultants shall be responsible for obtaining any building permit or certificate of occupancy for the Premises and that
obtaining the same shall be Tenant's responsibility.  Tenant shall have the right to submit to the City, at Tenant's sole risk and expense, a  coordinated set of
the Construction Drawings, complete to the extent required to commence the plan check and the first phase in the permitting process (the "Permit Set"), prior
to  approval  of  the  Construction  Drawings  by  Landlord.  Notwithstanding  anything  to  the  contrary  contained  herein,  Tenant  acknowledges  the  fact  that
Landlord may disapprove of and/or request changes to the Construction Drawings that Tenant submits to the City prior to Landlord reviewing and approving
of same and that there is an inherent risk that Tenant will incur delays, additional costs, and additional liabilities arising or resulting from Tenant's premature
submission  of  such  Construction  Drawings  to  the  applicable  governmental  agencies  prior  to  Landlord  reviewing  and  approving  same.    Tenant  agrees  to
indemnify, defend and hold harmless Landlord and Landlord Parties from any Claims arising from Tenant's submission of the Construction Drawings to the
applicable governmental authorities prior to Landlord reviewing and approving of same (and Tenant acknowledges that Landlord shall not be responsible for
any delays or costs incurred by Tenant in the event that Landlord requires revisions to the Construction Drawings after the date of such submission of plans to
the City by Tenant).  No material changes, modifications or alterations in the Approved Working Drawings may be made without the prior written consent of
Landlord.  

SECTION 4

CONSTRUCTION OF THE TENANT IMPROVEMENTS

4.1

Tenant's Selection of Contractors.

4.1.1

The Contractor.  A licensed general contractor shall be retained by Tenant to construct the Tenant Improvements and
Tenant shall contract directly with such "Contractor".  Landlord may file a Notice of Non-Responsibility regarding payments under Tenant's contract with the
Contractor.    Such  general  contractor  ("Contractor")  shall  be  selected  by  Tenant  from  a  list  of  general  contractors  supplied  by  Tenant  and  approved  by
Landlord.  Dome Construction Corporation is hereby approved as Contractor if selected by Tenant.   

1111154v7

Exhibit B—Page 7

 
 
 
 
4.1.2

Tenant's  Agents.    All  subcontractors,  laborers,  materialmen,  and  suppliers  used  by  Tenant  (such  subcontractors,
laborers, materialmen, and suppliers, and the Contractor to be known collectively as "Tenant's Agents") must be approved in writing by Landlord, which
approval  shall  not  be  unreasonably  withheld,  conditioned  or  delayed.    If  Landlord  does  not  approve  any  of  Tenant's  proposed  subcontractors,  laborers,
materialmen or suppliers, Tenant shall submit other proposed subcontractors, laborers, materialmen or suppliers for Landlord's written approval.

4.2

Construction of Improvements by Tenant's Agency.

4.2.1

Construction Contract.   Tenant  shall  engage  the  applicable  Contractor  under  a  commercially  reasonable  construction
contract (the "Contract"), provided that such Contract shall (a) require the Contractor to comply with the insurance and licensing requirements of this Lease
as well as the terms of Sections 4.2.1 and 4.2.2.3, below, and otherwise such insurance and indemnification provisions in a form reasonably acceptable to
Landlord; and (b) include a customary retainage.  Prior to the commencement of the construction of the Tenant Improvements, and after Tenant has accepted
all bids for the Tenant Improvements, Tenant shall provide Landlord with a detailed breakdown, by trade, of the final costs to be incurred or which have been
incurred in connection with the design and construction of the Tenant Improvements to be performed by or at the direction of Tenant or the Contractor, which
costs form a basis for the amount of the Contract (the "Final Costs").  In the event that the Final Costs are greater than the amount of the Tenant Improvement
Allowance (the "Over-Allowance Amount"), then Tenant shall pay a percentage of each amount requested by the Contractor or otherwise to be disbursed
under the Work Letter, which percentage shall be equal to the Over-Allowance Amount divided by the amount of the Final Costs (after deducting from the
Final Costs any amounts expended in connection with the preparation of the Construction Drawings, and the cost of all other Tenant Improvement Allowance
Items incurred prior to the commencement of construction of the Tenant Improvements), and such payments by Tenant ( the "Over-Allowance Payments")
shall be a condition to Landlord's obligation to pay any amounts from the Tenant Improvement Allowance.  In the event that, after the Final Costs have been
delivered by Tenant to Landlord, the cost relating to the design and construction of the Tenant Improvements shall change, any additional cost for such design
and construction in excess of the Final Cost shall be added to the Over-Allowance Amount and the Final Cost, and the Over-Allowance Payments shall be
recalculated in accordance with the terms of the immediately preceding sentence.  In connection with any payment of the Over-Allowance Amount made by
Tenant  pursuant  to  this  Section  4.2.1,  Tenant  shall  provide  Landlord  with  the  documents  described  in  Sections  2.2.2.1  of  this  Work  Letter,  above,  for
Landlord's approval, prior to Tenant paying such costs.  Notwithstanding anything set forth in the Work Letter to the contrary, construction of each component
of  the  Tenant  Improvements  shall  not  commence  until  Tenant  has  procured  and  delivered  to  Landlord  a  copy  of  all  permits  for  the  applicable  Tenant
Improvements.  Except as otherwise expressly set forth herein, Tenant shall be responsible for all costs incurred in connection with the construction of the
Tenant Improvements in excess of the Tenant Improvement Allowance; provided that Tenant shall continue to provide Landlord with the documents described
in Sections 2.2.2.1(i), (ii), (iii) and (iv) of this Work Letter

4.2.2

Tenant's Agents.

4.2.2.1

Landlord's General Conditions for Tenant's Agents and Tenant Improvement Work.  Tenant's and Tenant's
Agent's  construction  of  the  Tenant  Improvements  shall  comply  with  the  following:  (i)  the  Tenant  Improvements  shall  be  constructed  in  a  good  and
workmanlike manner, using only new materials, and in strict accordance with the Approved Working Drawings, Legal Requirements, the Private Restrictions
and  all  permits,  governmental  approvals  and  conditions  of  approval  (Tenant  shall  provide  Landlord  with  copies  of  such  permits  and  approvals  prior  to
commencing construction of the Tenant Improvements); and (ii) Tenant shall abide by all commercially reasonable rules made by Landlord's Project manager
with respect to the use of loading docks, storage of materials, coordination of work with the contractors of other tenants, and any other matter in connection
with this Tenant Work Letter, including, without limitation, the construction of the Tenant Improvements.

4.2.2.2

Indemnity.  Tenant's indemnity of Landlord as set forth in this Lease shall also apply with respect to any
and all Costs resulting from any act or omission of Tenant or Tenant's Agents, or anyone directly or indirectly employed by any of them, or in connection with
Tenant's  non-payment  of  any  amount  arising  out  of  the  Tenant  Improvements  and/or  Tenant's  disapproval  of  all  or  any  portion  of  any  request  for
payment.  Such indemnity by Tenant, as set forth in this Lease, shall also apply with respect to any and all Claims resulting from Landlord's performance of
any ministerial acts reasonably necessary (i) to permit Tenant to complete the Tenant Improvements, and (ii) to enable Tenant to obtain any Project permit or
certificate  of  occupancy  for  the  Premises;  provided,  however,  that  such  indemnity  shall  not  apply  to  any  Claims  resulting  from  Landlord's  negligence  or
willful misconduct.

1111154v7

Exhibit B—Page 8

 
 
 
 
4.2.2.3

Requirements of Tenant's Agents.  Each of Tenant's Agents shall guarantee to Tenant that the portion of
the Tenant Improvements for which it is responsible shall be free from any defects in workmanship and materials for a period of not less than one (1) year
from the date of completion thereof.  Tenant agrees that Landlord shall have the benefit of all such guarantees available to Tenant and relating to the portions
of  the  Project  that  Landlord  is  responsible  for  maintaining.    In  furtherance  of  the  foregoing,  Tenant  shall  assign  such  guarantees  to  Landlord  on  a
nonexclusive basis to the extent such assignment is necessary in order to make any such guarantees available to Landlord.  Each of Tenant's Agents shall be
responsible for the replacement or repair, without additional charge, of all work done or furnished in accordance with its contract that shall become defective
within one (1) year after the completion of the work performed by such contractor or subcontractors.   The  correction  of  such  work  shall  include,  without
additional  charge,  all  additional  expenses  and  damages  incurred  in  connection  with  such  removal  or  replacement  of  all  or  any  part  of  the  Tenant
Improvements, and/or the Project and/or common areas that may be damaged or disturbed thereby.  All such guarantees as to materials or workmanship of or
with respect to the Tenant Improvements shall be contained in the Contract or subcontract.  If, despite the foregoing, Landlord is unable to directly enforce
such guarantees, then Tenant shall reasonably cooperate with Landlord to enforce such guarantees with respect to the portions of the Project that Landlord is
responsible for maintaining.

Lien-Free Basis.  Tenant's Contractor and Tenant's Agents shall perform all work on a lien-
free basis.  If a lien is filed or recorded against the Project due to, or in any way associated with, the construction of the Tenant Improvements, then Section 28
of the Lease shall govern and control.  

4.2.2.3.1

4.2.2.4

Insurance Requirements.  All of Tenant's Agents shall comply with Section 9(a)(vi) of the Lease.

Governmental Compliance.  The Tenant Improvements shall comply in all respects with the following: (i) the Code and
other state, federal, city or quasi-governmental laws, codes, ordinances and regulations, Legal Requirements and the Private Restrictions as each may apply
according to the rulings of the controlling public official, agent or other person; and (ii) Project material manufacturer's specifications.

4.2.3

4.2.4

Inspection by Landlord.  Landlord shall have the right to inspect the Tenant Improvements at all times during the course
of  the  construction  thereof,  provided  however,  that  Landlord's  failure  to  inspect  the  Tenant  Improvements  shall  in  no  event  constitute  a  waiver  of  any  of
Landlord's  rights  hereunder  nor  shall  Landlord's  inspection  of  the  Tenant  Improvements  constitute  Landlord's  approval  of  the  same.    Should  Landlord
disapprove  any  portion  of  the  Tenant  Improvements  (which  disapproval  shall  be  limited  to  matters  relating  to  the  failure  of  the  Tenant  Improvements  to
conform  to  Legal  Requirements,  the  Private  Restrictions,  the  Approved  Working  Drawings,  or  to  otherwise  comply  with  the  terms  of  this  Work  Letter),
Landlord  shall  notify  Tenant  in  writing  of  such  disapproval  and  shall  specify  the  items  disapproved.   Any  defects  or  deviations  in,  and/or  disapproval  by
Landlord of, the Tenant Improvements in accordance with the terms and conditions contained herein, shall be rectified by Tenant at no expense to Landlord,
provided  however,  that  in  the  event  Landlord  disapproves  of  any  matter  in  connection  with  any  portion  of  the  Tenant  Improvements  and  such  matter  is
reasonably  likely  to  cause  imminent  danger  to  persons  or  property,  adversely  affect  the  mechanical,  electrical,  plumbing,  heating,  ventilating  and  air
conditioning or life-safety systems of the Premises or Project, the structure or exterior appearance of the Premises or Project or any other tenant's use of such
other tenant's leased premises and Tenant fails to commence to cure the same within two (2) business days of its receipt of Landlord's written notice, then
Landlord may, take such action as Landlord deems necessary, at Tenant's expense and without incurring any liability on Landlord's part, to correct any such
matter, including, without limitation, causing the cessation of performance of the construction of the Tenant Improvements until such time as the matter is
corrected to Landlord's reasonable satisfaction.

4.2.5

Meetings.  Commencing upon the Effective Date of the Lease, Tenant and Landlord shall hold meetings as required at a
reasonable time, with the Architect and the Contractor regarding the progress of the preparation of Construction Drawings and the construction of the Tenant
Improvements, which meetings may be held via teleconference or web-based videoconferencing, and Landlord and/or its agents shall receive a minimum of
five  (5)  business  days  prior  notice  of,  and  shall  have  the  right  to  attend,  all  such  meetings,  and,  upon  Landlord's  request,  certain  of  Tenant's  Agents  shall
attend such meetings.  

1111154v7

Exhibit B—Page 9

 
 
 
 
4.3

Notice of Completion.  No fewer than ten (10) days prior to the anticipated date of completion of construction of each component of
the Tenant Improvements that is being constructed pursuant to a separate construction contract and/or permit, Tenant shall provide Landlord with a Notice of
Completion  for  Landlord's  review  and  if  Landlord  approves  of  such  Notice  of  Completion,  upon  completion  of  the  applicable  portion  of  the  Tenant
Improvements (as evidenced by, at a minimum, final sign off and approval of the applicable portion of the Tenant Improvements by the municipal building
inspector), Landlord shall execute same and Tenant shall cause the same to be recorded in the office of the Recorder of the County in which the Premises is
located, and shall furnish a copy thereof to Landlord upon such recordation. If Tenant fails to provide any Notice of Completion for Landlord's review, the
same  shall  not  be  deemed  an  Event  of  Default  hereunder,  but  Landlord  may  request  Tenant  to  provide  Landlord  with  such  Notice  of  Completion  for
Landlord's review and Tenant shall provide the same to Landlord within ten (10) business days following receipt of such written request. If Tenant fails to
provide any such Notice of Completion to Landlord within such timeframe, then either (i) the same may be treated as an Event of Default after the expiration
of applicable notice and cure periods, or (ii) Landlord may execute and file the same on behalf of Tenant as Tenant's agent for such purpose, at Tenant's sole
cost  and  expense.  Tenant  shall  also,  within  ten  (10)  days  following  recordation  of  a  Notice  of  Completion,  provide  a  copy  of  the  recorded  Notice  of
Completion, pursuant to California Civil Code §8190, to (i) Contractor, (ii) Tenant's Agents, and (iii) any other claimant that has issued a preliminary notice
in  conjunction  with  the  applicable  portion  of  the  Tenant  Improvements;  and  Tenant  shall  provide  Landlord  with  evidence  of  proof  of  service  to  all  such
parties.  If Tenant fails to perform any of the foregoing, without limiting any of the foregoing remedies contained herein or in the Lease, Landlord may do so
as Tenant's agent for such purpose (at Tenant's sole cost and expense).

5.4

Tenant's Lease Default.  Notwithstanding any provision to the contrary contained in this Lease, if an Event of Default as described in
the Lease or this Tenant Work Letter has occurred at any time, then (i) in addition to all other rights and remedies granted to Landlord pursuant to this Lease,
Landlord shall have the right to withhold payment of all or any portion of the Tenant Improvement Allowance and/or Landlord may cause Contractor to cease
the construction of the Premises until such time as such Event of Default is cured (in which case, Tenant shall be responsible for any delay in the substantial

5.5

Additional Services.  If the construction of the Tenant Improvements shall require that additional services or facilities (including, but

shall  pay  Landlord  for  such  items  at  Landlord's  cost  or  at  a  reasonable  charge  if  the  item  involves  time  of  Landlord's  personnel  only.  Tenant  hereby
acknowledges  and  agrees  that  Tenant  will  be  required  by  the  local  governmental  authority  with  jurisdiction  over  the  Premises  to  install  security  cameras

requirements of any governmental authority during construction of the Tenant Improvements (including, without limitation, the installation and monitoring of
such security cameras).

contractor or subcontractors, or by reason of inadequate cleanup following completion of the Tenant Improvements.  

5.7

Coordination of Labor.  All of Tenant's contractors, subcontractors, employees, servants and agents must work in harmony with and
shall not interfere with any labor employed by Landlord, or Landlord's contractors or by any other tenant or its contractors with respect to any portion of the
Project.  Landlord shall not impose any requirement that Tenant be required to use union contractors; provided, however, that if Tenant retains non-union
contractors and the presence of such non-union contractors interferes with the performance of the Landlord Work (a “Labor Problem”), then if Tenant does
not resolve such Labor Problem (including through the potential use of a “dual gate” system) within two (2) days following written notice from Landlord,
Tenant shall immediately cease using the non-union contractors that are the cause of the Labor Problem.  Any delay to the Landlord Work caused by any
Labor Problem shall constitute a Tenant Delay.

5.8

Work in Adjacent Areas.  Subject to compliance with Legal Requirements and any Private Restrictions, any work to be performed in
areas  adjacent  to  the  Premises  shall  be  performed  only  after  obtaining  Landlord's  express  written  permission,  which  shall  not  be  unreasonably  withheld,
conditioned or delayed.

Exhibit B—Page 11

 
 
 
 
5.9

Building Systems.  Tenant agrees to be entirely responsible for the maintenance or the balancing of any heating, ventilating or air
conditioning system installed by Tenant and/or maintenance of the electrical or plumbing work or life safety improvements installed by Tenant and/or for
maintenance of lighting fixtures, partitions, doors, hardware or any other installations made by Tenant.  

5.10

Approval of Plans.  Landlord will not check Tenant drawings for building code compliance or compliance with Legal Requirements
and/or  the  Private  Restrictions.   Approval  of  the  Construction  Drawings  by  Landlord  is  not  a  representation  that  the  drawings  are  in  compliance  with  the
requirements of governing authorities, and it shall be Tenant's responsibility to meet and comply with all federal, state, and local code requirements.  Approval
of the Construction Drawings does not constitute assumption of responsibility by Landlord or its architect for their accuracy, sufficiency or efficiency, and
Tenant shall be solely responsible for such matters.

5.11

Landlord Delays.  For purposes of this Work Letter and the Lease, "Landlord Delays" means actual delays in the completion of the
Tenant Improvements by the expiration of the Buildout Period to the extent resulting from (a) the failure of Landlord (but not any design review committee or
owner's association) to timely approve or disapprove any of Tenant's submittals pursuant within the express timeframes provided in Section 3.2 above; or (b)
material  interference  by  Landlord  or  the  Landlord  Parties  with  the  construction  of  the  Tenant  Improvements  following  Substantial  Completion  of  the
Landlord Work.  If Tenant contends that a Landlord Delay has occurred under clause (b), then no Landlord Delay shall have occurred unless and until Tenant
has provided Landlord's Representative (as defined above) with email notice specifying that a Landlord Delay may result from Landlord's continued actions
or  failure  to  act,  and  Landlord  does  not  cease  or  complete  (as  the  case  may  be)  such  actions  within  one  (1)  business  day  after  receipt  of  such  email
notice.  With respect to other delays under clause (a), Tenant shall provide Landlord's Representative with email notice within ten (10) days following the date
Tenant actually becomes aware of the delay; provided, however, there shall be no cure period with respect to such delays and the Landlord Delay shall be
deemed to have occurred (and started accruing) on the actual day the Landlord Delay occurred. Notwithstanding the foregoing, the Landlord Delay shall be
deemed to have ceased on the date that Landlord is deemed to have approved of any of Tenant's submittals pursuant to Section 3.2 above.  The Buildout
Period shall be extended on a day-for-day basis for each day of a Landlord Delay.

5.12

Miscellaneous Charges. During construction of the Tenant Improvements and Tenant's initial move-in prior to the Commencement
Date, neither Tenant, Tenant's Agents nor the Contractor shall be charged for the use of parking at the Building, HVAC, electricity, water, or, during normal
construction hours, freight elevator and/or loading docks.

Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the
statements made, in light of the circumstances under which such statements were made, not misleading with respect to the period covered by this

Based on my knowledge, the financial statements, and other financial information included in this report, fairly present in all material respects the
financial condition, results of operations and cash flows of the registrant as of, and for, the periods presented in this report;

The registrant's other certifying officer(s) and I are responsible for establishing and maintaining disclosure controls and procedures (as defined in

(a)

(b)

(c)

Designed such disclosure controls and procedures, or caused such disclosure controls and procedures to be designed under our supervision, to
ensure that material information relating to the registrant, including its  subsidiaries, is made known to us by others within those entities,
particularly during the period in which this report is being prepared;

Evaluated the effectiveness of the registrant's disclosure controls and procedures and presented in this report our conclusions about the
effectiveness of the disclosure controls and procedures, as of the end of the period covered by this report based on such evaluation; and

Disclosed in this report any change in the registrant's internal control over financial reporting that occurred during the registrant's most recent
fiscal quarter (the registrant's fourth fiscal quarter in the case of an annual report) that has materially affected, or is reasonably likely to
materially affect, the registrant's internal control over financial reporting; and

5.

The registrant's other certifying officer(s) and I have disclosed, based on our most recent evaluation of internal control over financial reporting, to the
registrant's auditors and the audit committee of the registrant's board of directors (or persons performing the equivalent functions):

(a)

(b)

All significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which are reasonably
likely to adversely affect the registrant's ability to record, process, summarize and report financial information; and

Any fraud, whether or not material, that involves management or other employees who have a significant role in the registrant's internal control
over financial reporting.
