Summary of the Material and Other Risks Associated with Our Business

•

•

•

•

•

•

•

•

•

•

•

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

Our business is highly dependent on the success of ADI-001. If we are unable to obtain approval for ADI-001 and effectively commercialize 
ADI-001 for the treatment of patients in our approved indications, our business would be significantly harmed.

Our gamma delta T cell candidates represent a novel approach to cancer treatment that creates significant challenges for us.

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

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.

We may not be able to file investigational new drug (IND) applications 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 may encounter substantial delays in our clinical trials or may not be able to 
conduct our trials on the timelines we expect.

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.

We do not currently operate our own manufacturing facility and currently depend on the ability of our third-party suppliers and 
manufacturers with whom we contract to perform adequately, particularly with respect to the timely production and delivery of our product 
candidates, including ADI-001. This reliance on third parties increases the risk that we will not have sufficient quantities of our product 
candidates or products or such quantities at an acceptable cost, which could delay, prevent or impair our development or commercialization 
efforts.

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.

Business disruptions could seriously harm our future revenue and financial condition and increase our costs and expenses. A pandemic, 
epidemic or outbreak of an infectious disease, such as COVID-19, may materially and adversely affect our business and operations.

Failure to achieve and maintain effective internal control over financial reporting could harm our business and negatively impact the value of 
our common stock.

If our collaboration agreement with Regeneron Pharmaceuticals, Inc. (Regeneron) is terminated, or if Regeneron materially breaches its 
obligations thereunder, our business, prospects, operating results, and financial condition would be materially harmed.

The U.S. Food and Drug Administration 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.

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 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 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.

EXPLANATORY NOTE 

Prior to September 15, 2020, we were a clinical-stage biopharmaceutical company known as resTORbio, Inc. (resTORbio) that had historically 
focused on developing innovative medicines that target the biology of aging, to prevent or treat age-related diseases with the potential to extend healthy 
lifespans. resTORbio was originally incorporated under the laws of the State of Delaware in July 2016 and commenced research and development 
operations in March 2017.

On September 15, 2020, we completed our business combination whereby a wholly-owned subsidiary of resTORbio merged with and into Adicet Bio, 
Inc. (Former Adicet), with Former Adicet surviving as a wholly-owned subsidiary of resTORbio and changing our name to Adicet Therapeutics, Inc. (such 
transactions, the Merger). In connection with the completion of the Merger, resTORbio was renamed Adicet Bio, Inc. (Adicet Bio).

Immediately prior to the Effective Time of the Merger, resTORbio effected a reverse stock split of our common stock at a ratio of 1-for-7 (the Reverse 

Stock Split). At the Effective Time of the Merger, each outstanding share of Former Adicet’s capital stock was converted into the right to receive 0.1240 
(the Exchange Ratio) shares of Adicet Bio’s common stock.

Unless otherwise noted, all references to common stock share and per share amounts in this Annual Report on Form 10-K have been retroactively 

adjusted to reflect the conversion of shares in the Merger based on the Exchange Ratio and Reverse Stock Split. As used herein, the words “Adicet Bio,” 
“Adicet,” “the Company,” “we,” “us,” and “our” refer to, for periods following the Merger, Adicet Bio (formerly resTORbio, Inc.), together with its direct 
and indirect subsidiaries, and for periods prior to the Merger, Adicet Therapeutics, Inc. (formerly Adicet Bio, Inc.).  In addition, the word “resTORbio” 
refers to the Company prior to the completion of the Merger, and we sometimes refer to Adicet Therapeutics, Inc. as “Former Adicet.”

Item 1. Business.

Overview

We are a clinical stage biotechnology company discovering and developing allogeneic gamma delta T cell therapies for cancer. We are advancing a 
pipeline of “off-the-shelf” gamma delta T cells, engineered with chimeric antigen receptors (CAR) and T cell receptor-like antibodies (TCRL), to enhance 
selective tumor targeting, facilitate innate and adaptive anti-tumor immune response, and improve persistence for durable activity in patients. Our approach 
to activate, engineer and manufacture allogeneic gamma delta T cell product candidates derived from the peripheral blood cells of unrelated donors allows 
us to generate new product candidates in a rapid and cost-efficient manner. 

Our lead product candidate, ADI-001, a first-in-class allogeneic gamma delta T cell therapy expressing a CAR targeting CD20, is in an ongoing Phase 
1  study  for  the  treatment  of  Non-Hodgkin's  Lymphoma  (NHL).  Our  pipeline  also  includes  ADI-002,  an  allogeneic  gamma  delta  CAR-T  cell  therapy 
expressing a GPC3-targeted CAR and a cell intrinsic soluble form of interluiken-15 (IL-15), for the treatment of solid tumors. In addition, we are engaged 
in  discovery  and  preclinical  stage  activities  directed  to  expansion  of  our  pipeline  of  product  candidates  for  both  hematological  malignancies  and  solid 
tumors.

Our Approach

Our proprietary engineering and manufacturing process begins with isolating and expanding gamma delta T cells from the blood of unrelated donors, 
and results in the potential to treat up to 1,000 patients per batch depending on dosing and the CAR target. Gamma delta T cells have unique attributes that 
we believe make them especially well-suited to be used for cancer therapy. Approximately 95% of T cells in circulation are so-called alpha beta T cells, 
named after the proteins that make up the cells’ T cell receptor (TCR). The remaining T cells include a population that makes up between 1% and 5% of all 
T cells, the gamma delta T cells, along with a few other cell types. Distinct among immune cell populations, we believe gamma delta T cells may have the 
following combination of attributes:

•

•

•

Can be used in patient irrespective of the tissue-types of the patient i.e., a “universal” product;

Can be used “off-the-shelf” after being expanded from unrelated donors; 

Are actively cytotoxic to tumor cells;

• May functionally persist in patients for clinically meaningful periods or time;

•

•

•

Can replicate in an appropriate and measured way after manufacture and administration; Can have their reactivity to tumor cells enhanced further 
by the addition of a CAR;

Express both T cell and natural killer (NK) cell receptors, facilitating both adaptive and innate anti-tumor immune responses; and

Can be manufactured potentially in large numbers to facilitate the consistent treatment of many patients and avoids the cumbersome nature and 
expense of isolating cells from each patient.

By  contrast,  approved  CAR-T  cell  therapies,  as  well  as  the  majority  of  CAR-T  cell  therapies  in  clinical  development,  are  based  on  a  different 
population of T cells, known as alpha beta T cells, which have the ability to attack unrelated tissues if they are not immunologically matched to the patient. 
For  this  reason,  the  majority  of  alpha-beta-T-cell-derived  CAR-T  cell  products  are  custom-generated  from  cells  isolated  from  each  patient,  or  require 
significant gene editing to manufacture if the T cells are derived from donors that are unrelated to the patient. Gamma delta T cells, by contrast, do not in 
principle  require  immunological  matching  and  therefore  cells  isolated  from  unrelated  donors  can  potentially  be  administered  to  any  patient.  This  may 
enable cell therapy products based on gamma delta T cells to be manufactured in bulk and distributed as readily available off-the-shelf products. In animal 
models and early third-party clinical trials, gamma delta T cells do not expand in healthy tissues, indicating that they may be associated with a lower risk of 
life-threatening immune responses. In addition to their ability to circulate, gamma delta T cells have an inherent capacity to locate in tissues and recognize 
and attack cancerous cells.

5

 
In  comparison  to  a  number  of  NK  cell  therapies  currently  in  development,  CAR-modified  gamma  delta  T  cells  functionally  persist  in  non-clinical 
models  for  protracted  periods  of  time  and  are  designed  to  persist  after  single  or  repeat  dosing  of  patients  for  clinically  meaningful  periods.  Our 
manufacturing process results in highly homogeneous cell populations that we have observed to display potent anti-tumor activity in non-clinical models. 
Unlike most NK cells, that only exhibit characteristics on innate lymphocytes, gamma delta T cells display features of both innate and adaptive anti-tumor 
immunity and readily recognize and kill tumor cells with and without expression of CARs. Additionally, we believe that our short proprietary process to 
manufacturing  CAR-modified  gamma  delta  T  cells  without  any  “feeder”  cell  lines  compares  favorably  to  manufacturing  alternatives  used  in  expanded 
allogeneic NK cell-based therapies. 

Our Pipeline

Our lead product candidate, ADI-001, a first-in-class allogeneic gamma delta T cell therapy expressing a CAR targeting CD20, is in an ongoing Phase 
1 study for the treatment of NHL. On December 6, 2021, we reported positive interim clinical data from the initial dose escalation portion of this study that 
showed complete and near complete responses at low doses along with a generally favorable tolerability profile. We aim to provide a further clinical update 
for ADI-001 in the first half of 2022. 

Our  pipeline  also  includes  three  other  product  candidates  in  the  discovery  or  preclinical  phases  for  which  we  aim  to  file  investigational  new  drug 

(IND) applications between 2023 and 2025. 

As part of a collaboration with Regeneron Pharmaceuticals, Inc. (Regeneron) pursuant to an agreement signed in 2016, Regeneron has the option to 
obtain  development  and  commercial  rights  for  a  certain  number  of  product  candidates,  and  we  have  an  option  to  participate  in  the  development  and 
commercialization of these potential products or are entitled to royalty payments by Regeneron. Immunocellular therapy product candidates developed and 
commercialized  by  us  under  our  agreement  with  Regeneron  will  be  subject  to  payment  of  royalties  to  Regeneron.  On  January  28,  2022,  Regeneron 
exercised its option to license exclusive rights to ADI-002. For additional information on our agreement with Regeneron, please see the section entitled 
“Business—Strategic Agreements” of this Annual Report on Form 10-K.

Our Strategy

Our objective is to be the leading biotechnology company developing CAR-modified gamma delta T cells for oncology. Key elements of our strategy 

include our plans to:

•

Continue to advance clinical development of ADI-001. ADI-001, our lead hematologic cancer product candidate, is currently in an ongoing 
Phase 1 study for the treatment of NHL. CD20 is a well validated target for immunotherapy for NHL. Our goal is to capitalize on our leadership 
in  engineered  allogeneic  anti-CD20  gamma  delta  CAR  T  cell  therapy  and  pursue  a  broad  clinical  development  plan  for  multiple  subtypes  of 
NHL.

•

•

Continue to innovate and invest in the gamma delta T cell platform and pipeline. We expect to continue to develop product candidates in 
oncology  based  on  the  gamma  delta  T  cell  platform  using  either  previously  validated  antigens  or  those  that  we  identify  and  target  using  our 
TCRL technology. We may utilize additional genetic engineering, editing technologies or other technologies with the goal of further improving 
the activity and tolerability profile of our product candidates. A key strength of our gamma delta T cell therapy platform lies in our ability to 
target  antigens  of  both  known  and  unknown  potential  and  devote  our  clinical  development  resources  to  those  antigens  that  show  the  most 
promise in preclinical in vivo analyses and early human trials.

Exploit the potential for outpatient administration. While we expect that the initial subjects receiving our gamma delta T cell-based therapies 
in  clinical  studies  will  be  hospitalized  for  a  minimum  of  24-hour  observation  after  infusion,  a  favorable  tolerability  profile  may  allow 
administration of such investigational therapies in an outpatient setting. We believe this would represent a significant competitive advantage for 
our gamma delta T cell-based therapies as compared to existing approved CAR-T cell therapies.

Expand and protect our intellectual property. We will continue to aggressively protect the gamma delta T cell production methodology we 
have developed as well as specific product candidates based on proprietary antigen-binding domains. For more information on our intellectual 
property, see “Business— Our Intellectual Property” of this Annual Report on Form 10-K.

Background

Anticancer Immune Cell Therapy

In recent years, the field of immuno-oncology has advanced numerous therapies for the treatment of cancer. Immuno-oncology deploys the immune 
system to attack and, in some cases, to eliminate cancer. One of the key breakthroughs in immuno-oncology involved using T cells, a key element of the 
immune system, and turning them into even more potent, tumor-cell-specific killers. Researchers have achieved this improvement and targeting by loading 
the T cells with a gene encoding a CAR. These engineered receptors represent a powerful combination of, first, a region that binds to a target on a cancer 
cell and tethers the T cell to it; and second, a signal that activates the T cell to eliminate the tethered cancer cell. To our knowledge, all marketed CAR-T 
cells contain predominantly alpha beta T cells. While we believe the use of CAR-T cell therapies is promising, conventional CAR-T cell therapies also 
have some key flaws that, we believe, can potentially be addressed by using a cell population, specifically, gamma delta T cells rather than alpha beta T 
cells.

As  of    December  31,  2021,  four  CD19-targeting  CAR-T  cell  therapies  have  been  approved  by  the  FDA  for  the  treatment  of  B  cell  lymphomas: 
axicabtagene  ciloleucel  (Yescarta®)  and  brexucabtagene  autoleucel  (Tecartus™)  developed  by  Kite  Pharma,  now  Gilead  Sciences,  Inc.  (Gilead); 
tisagenlecleucel (Kymriah®), developed by Novartis; and lisocabtagene maraleucel (Breyanzi®) developed by Juno Therapeutics, Inc. (now Bristol Myers 
Squibb Company). Among the 111 patients with diffuse large B cell lymphoma, (DLBCL), treated with Yescarta® in a clinical trial, an objective response 
rate of 82% was observed with 54% of patients achieving a complete response. This high efficacy, however, is associated with significant adverse events, 
with 13% of patients experiencing grade 3 or higher cytokine release syndrome and 28% of patients experiencing grade 3 or higher neurologic events. In 
the Yescarta® DLBCL clinical trial, three patients died due to adverse events during treatment and ten patients who were enrolled in the trial were not able 
to be treated due to disease progression or complications that arose during the period of time required to generate the patient-specific therapy or because of 
the inability to generate the desired CAR-T cells from the patient’s cells. We believe that, despite their progress to date, currently available CAR-T cell 
therapies have not reached their full promise, and our gamma delta CAR-T cell approach has the potential to be a significant improvement.

The current generation of approved CAR-T cell therapies for B cell lymphomas represented by Yescarta®, Tecartus™, Breyanzi®, and Kymriah® are 
autologous cell therapies, that is, they are based on immune cells isolated from a patient, modified and expanded in a laboratory and then reintroduced into 
the same patient. One key reason for taking this autologous approach is that the cytotoxic, or, cell-killing, cells are predominantly alpha beta T cells that are 
used  to  generate  these  therapies  and  are  cells  that  the  immune  system  uses  to  recognize  and  attack  foreign  cells.  If  these  types  of  T  cells  were  to  be 
introduced into a patient from an unrelated donor, the donor T cells would attack healthy tissues throughout the patient in a process known as graft versus 
host disease (GvHD) potentially causing multiple organ failure and death.

The T cells used for first-generation CAR-T cell therapies were derived from a highly abundant subclass of T cells known as alpha beta T cells. Alpha 
beta T cells, which comprise approximately 95% of the T cells in circulation in the body, are able to distinguish whether cells that they encounter are either 
normal cells that belong in the body or foreign or damaged cells that need to be destroyed. Alpha beta T cells have a receptor on their surface called a TCR 
which is made up of alpha and beta protein chains. These TCRs recognize targets, also known as antigens, on cells that are presented by antigen-presenting 
molecules encoded by the major histocompatibility complex (MHC). The MHC contains genes that encode a number of proteins with multiple variants, 
such that most individuals have a distinct MHC profile. During normal T cell development, those T cells that recognize the combination of the specific 
MHC profile and antigens that are presented by healthy cells of the specific individual are eliminated, resulting in a population of T cells that circulate 
throughout the body, vigilantly checking for abnormal antigens or foreign cells, including from another individual.

7

 
In one type of cellular immunotherapy known as adoptive cell therapy, naturally occurring immune cells from a patient are isolated and are activated 
using cytokines and tumor-specific antigens to stimulate the growth and expansion of antitumor T cells that already exist at low abundance in the patient. 
After activation and expansion in the laboratory, large numbers of T cells that are primed to recognize the tumor are reintroduced into the same patient.

CAR-T cell therapies are a variant of this adoptive cell therapy in which, instead of trying to activate T cells based on the ability of naturally occurring 
TCRs to recognize tumor antigens, a CAR designed to recognize a specific tumor antigen is genetically introduced into T cells. These CAR-T cells are then 
able to destroy any cells expressing the appropriate antigen completely independent of MHC. However, without further genetic engineering, CAR-T cells 
derived from alpha beta T cells still have endogenous TCRs which restrict their use to the original patient.

Limitations of autologous cell therapies

Autologous  cell  therapies,  such  as  those  developed  by  Kite  Pharma  and  Novartis,  have  a  number  of  limitations,  including  but  not  limited  to  the 

following:

•

Treatment delays imposed by individualized manufacturing. Due to the individualized manufacturing process, patients must wait up to three 
to four weeks for the individualized products to be manufactured and administered. In the registrational trials for Yescarta® and Kymriah®, up to 
31% of intended patients ultimately did not receive treatment primarily due to complications from the underlying disease that occurred during 
manufacturing or due to manufacturing failures.

• Manufacturing variability and failure. It was reported by Novartis in 2018 that variability in product specifications had been observed in the 
production of Kymriah®. In addition, in approximately 9% of the cases, no product could be shipped to patients at all due to out-of-specification 
issues or from manufacturing failures.

•

•

High cost limits patient access. The high cost of therapy and payer policies can limit access to autologous CAR-T cell therapies. According to a 
2019 article published in the journal Managed Care, treating physicians estimate that the costs of autologous CAR-T cell therapies combined 
with patient care services are approximately $1 million per patient, generating reluctance of payers to approve these therapies for patients before 
they have exhausted other options. These therapies are then relegated to the most heavily pretreated patients who may be unable to withstand the 
severe side effects.

Scalability. Because each patient requires a custom manufacturing batch, the production of autologous CAR-T cells at the scale needed to meet 
commercial demand and anticipated label and geographic expansions may be challenging.

Autologous  cell  therapies,  such  as  CAR-T  cells  derived  from  alpha  beta  T  cells,  have  been  successful  in  their  initial  use  in  hematological 
malignancies. Furthermore, they have provided critical data that demonstrates the potential of immunocellular cancer therapies. However, manufacturing of 
these cells imposes some critical limitations that could be minimized if similar allogeneic cell therapies that can be given to any patient, regardless of the 
donor of cells, are developed. We believe that allogeneic cell therapies offer great promise for optimizing the access to therapy, overcoming manufacturing-
related and cost-related limitations of autologous cell therapies.

Gamma delta T cells and their allogeneic potential

Gamma delta T cells are a subset of T cells that have TCRs comprising gamma and delta receptor chains. In contrast to alpha beta T cells, gamma 
delta T cells are not selective for patient-specific MHC molecules. Therefore, gamma delta T cells from an unrelated donor can be administered to a patient 
without inducing GvHD and may recognize tumor-associated antigens in an MHC-independent manner. Gamma delta T cells primarily reside in tissues and 
comprise between 1% and 5% of circulating T cells.

Gamma delta T cells correlate with improved outcomes

An analysis of the transcriptional profiles of 5,872 patient tumor samples across 25 malignancies published in Nature Medicine in 2015 found that 

gene signatures consistent with gamma delta T cells were the strongest predictors of overall survival. 

8

 
The association of gamma delta T cells with overall survival in solid tumors had a z-score over three, meaning it was over three standard deviations above 
the mean, corresponding to a p value less than 0.001.

Figure 2. Analysis of the immune cell composition of tumor samples that gamma delta T cells were highly predictive of overall survival. Adapted 
from Gentles et al., Nat Med. 2015; 21(8).

Additionally,  high  levels  of  gamma  delta  T  cells  have  been  associated  with  improved  overall  survival  in  acute  leukemia  patients  who  received 
hematopoietic stem cell transplants (HSCT). In a study published by KT Godder et al. in 2007 in the journal Bone Marrow Transplantation, those patients 
with high levels of gamma delta T cells after the transplant had a leukemia free survival at five-years of 54.4% and overall survival of 70.8%. Those with 
low levels of gamma delta T cells had a significantly lower five-year leukemia free survival of 19.1% and a five-year overall survival of 19.6%.

Figure 3. HSCT patients who develop high levels of gamma delta T cells have improved survival. Adapted from Godder et al., Bone Marrow 
Transplantation 2007; 39.

9

 
 
 
 
 
 
 
The correlation between high levels of gamma delta T cells and disease-free survival extends to patients with solid tumors. In a study published by 
Meraviglia et al in 2017 in the journal OncoImmunology, across a cohort of 557 patients with colorectal cancer, those with high gamma delta T cell levels 
had a five-year disease-free survival rate of over 80%, and revealed that disease-free survival probability was significantly higher in CRC patients with 
high number of tumor infiltrating gamma delta T cells.

Figure  4.  High  levels  of  gamma  delta  T  cells  are  correlated  with  increased  disease-free  survival  in  colorectal  cancer  patients.  Adapted  from 
Meraviglia et al., Oncoimmunology 2017; 6 (10).

We believe that these studies and others point to an important role of gamma delta T cells in disease control and overall survival and indicate that 

gamma delta T cell-based therapies have the potential to deliver clinically meaningful results.

Advantages of gamma delta T cell-based therapies

Immunotherapies developed using gamma delta T cells have a number of advantages over other therapies developed using other cell types, including 

the following:

•

Lack of GvHD. A body of published evidence, mainly in the field of HSCT, supports the safety profile of transfer of allogeneic gamma delta T 
cells to patient recipients from unrelated donors. HSCT procedures containing significant numbers of gamma delta T cells were able to proceed 
with no signs of acute or chronic GvHD. In many cases, the presence of gamma delta T cells in the HSCT products correlated with improved 
clinical outcomes, indicating the antitumor potential of gamma delta T cells. Additionally, a study performed by Martin Wilhelm and colleagues 
in 2014 indicated that gamma delta T cells from haploidentical donors could be successfully expanded and infused in large numbers (2.17x106 
cells / kg (range, 0.9-3.84)), followed by further expansion (mean, 68-fold) in the patients without any observed GvHD.

• MHC-independent tumor antigen recognition. Gamma delta TCR can recognize tumor associated antigens in a MHC-independent manner, 
facilitating  the  use  of  products  derived  from  donors  who  are  unrelated  to  patients  which  may  avoid  the  need  to  match  the  human  leukocyte 
antigen (HLA)-type of the donor to the patient.  

•

•

•

Tumor localization. In addition to being present in the circulation at low frequency, gamma delta T cells have an inherent propensity to home to 
tissues and tumors. Their ability to be activated in environments with low levels of oxygen such as those found in the tumor microenvironment 
has the potential to increase the activity of gamma delta T cells in solid tumors.

Limited cytokine secretion. Unlike alpha beta T cells, gamma delta T cells can be made to secrete lower levels of certain cytokines such as 
interleukin 2 (IL-2). This, combined with lack of recognition of normal, non-malignant, cells by of gamma delta T cells, may lower the risk of 
life-threatening cytokine release syndrome.

Limited  ability  for  tumors  to  escape.  Although  the  initial  responses  to  immunotherapies  such  as  antibodies  and  CAR-T  cells  are  often 
impressive, many patients become refractory or relapse. A common mechanism for the relapse to these therapies is loss of the expression of the 
CAR-targeted antigen such as CD19 from tumor cells. Because gamma delta 

10

 
  
 
 
T cells also express innate cytotoxic immune receptors, they can recognize and kill tumor cells even in the absence of the CAR-targeted tumor 
antigen.

•

•

•

Ability to manufacture more efficiently and cost-effectively. Unlike alpha beta T cells, therapies based on gamma delta T cells can potentially 
be manufactured in bulk and used in the allogeneic or off-the-shelf setting, addressing many of the shortcomings of conventional alpha beta T 
cell therapy.

Potential  for  superior  cytotoxic  activity.  T  cells  from  some  cancer  patients,  for  example  those  with  chronic  lymphocytic  leukemia,  often 
display an exhausted, or otherwise dysfunctional, phenotype and CAR-T cell products from these cells may perform poorly. Our allogenic cell 
therapy is manufactured from unrelated donors whose T cells have been proven to generate highly active CAR-T cell product.

Potential for re-dosing. Along with increased availability of material due to the ability to utilize off-the-shelf donor-derived starting material 
from unrelated donors compared to conventional CAR-T cell therapies, the lack of MHC-dependent GvHD also opens up the possibility of being 
able to re-dose patients to achieve further clinical activity if they do not obtain an adequate clinical response from initial treatment or if they 
relapse. A number of studies with other CAR-T cell therapies have linked the development of cytokine release syndrome with high numbers of 
circulating CAR T cells following rapid alpha beta T cell proliferation. Having the option to retreat patients with gamma delta T cells provides 
the option of starting with a low dose and re-dosing if required.

Our CAR gamma delta T cell technology

Human gamma delta T cells can be divided into three main subsets based on their TCR delta chain usage: Vδ1, Vδ2 and Vδ3. The most abundant 
subset of gamma delta T cells in the circulatory system, the Vδ2 cells, is also the most well-studied. However, it is the Vδ1 subset which primarily resides 
in tissues and presents a favorable cytotoxic anti-tumor profile that we are activating and manufacturing using our proprietary platform technology.

Vδ1 gamma delta T cells

Vδ1 cells have properties of both the innate and adaptive immune system, meaning that they can be activated by tumor-specific antigens as well as by 
general activators common to damaged or otherwise abnormal cells. Similar to other T cells, they express TCRs, but also express cytotoxicity receptors that 
are found on innate immune cells such as NK cells. These gamma delta T cells can induce tumor cell death through multiple mechanisms including the 
secretion of cytotoxic proteins such as granzymes and perforin as well as through the secretion of cytokines such as interferon gamma (IFNγ), and tumor 
necrosis factor alpha (TNFα).

In in vitro and in vivo preclinical cancer models, Vδ1 cells are more cytotoxic and may have a longer durability than Vδ2 cells. Vδ1 cells are also 
more resistant to activation induced cell death (AICD), which has posed significant problems in clinical trials following chronic stimulation of Vδ2 cells. 
Vδ1 cells normally reside within tissues and they are able to adapt to lower nutrient availability and decreased oxygen levels, conditions which are similar 
to those in the microenvironments or localized areas associated with certain solid tumors. Incubation of these gamma delta T cells in conditions of low 
oxygen (hypoxia) that are typical of tumors has been shown to enhance their cytotoxicity.

Anticipated advantages of Vδ1 gamma delta T cells over NK cell based therapies

An alternate approach to the development of allogeneic CAR T cells consists of engineered NK cell-based therapy. While both gamma delta T cell 
and NK cell therapy generally are not expected to cause GvHD, NK cells express a broad repertoire of both inhibitory and activating receptors and have 
more limited tumor induced secretion of multiple cytokines. We believe that the gamma delta T cell technology we are developing has several advantages 
over this approach. Unlike engineered NK cells, Vδ1 gamma delta T cells have the following advantages:

•

•

•

•

•

The presence of gamma delta cells in tumors is strongly correlated with positive clinical outcomes; 

Can display tumor-induced secretion of multiple cytokines including expressing high levels of interferon-gamma;

Can be produced as highly homogeneous cell populations that display potent non-clinical anti-tumor activity;

Express activating receptors more predominantly; and

Display  features  of  adaptive  immunity  including,  TCR-mediated,  but  MHC-independent,  tumor  antigen  recognition,  a  long  lifespan  and 
persistence for protracted periods of time;

11

 
We believe these advantages position gamma delta T cell-based therapies to become an attractive alternative to NK based therapies for many oncology 

indications and lines of therapy.

Anticipated advantages of Vδ1 gamma delta T cells over other approaches to generate allogeneic CAR-T cells

An alternative approach to the development of allogeneic gamma delta CAR T cells consists of introducing genetic modifications that disable the TCR 
in alpha beta T cells derived from donors that are unrelated to the patient. This process prevents these cells from attacking the patient’s healthy cells. We 
believe that the unrelated donor-derived gamma delta T cell technology, which lacks the ability to attack healthy cells from unrelated individuals, has a 
number of advantages over this approach. In an allogeneic paradigm, unlike alpha beta T cells, Vδ1 gamma delta T cells have the following advantages:

•

•

Do not rely on genetic manipulations to inactivate the alpha beta TCR;

Display properties of both adaptive and innate immune systems and are capable of killing cells even if their specifically targeted CAR antigen is 
expressed at low levels or not present;

• May not be prone to exhaustion and are likely to persist longer;

• May maintain the capacity to home to tissues and tumors rather than predominantly residing in circulation; and

• May be less likely to induce cytokine release syndrome due to more limited endogenous IL-2 secretion by activated cells.

We believe these advantages position gamma delta T cell based therapies to become an attractive alternative to alpha beta T cell based therapies.

Anticipated advantages of Vδ1 gamma delta T cells over bispecific antibody T cell recruitment for tumor immunotherapy

An  alternative  approach  to  the  development  of  allogeneic  CAR  T  cells  consists  of  bispecific  antibodies  that  are  designed  to  crosslink  T  cells  to 
specific targets on the tumor. This approach generally requires healthy and functional T cells able to attack the tumor when guided to the tumor expressing 
the target antigen. We believe that the unrelated donor-derived gamma delta T cell technology has a number of potential advantages over this approach. 
Unlike bispecific antibodies, Vδ1 gamma delta T cells have the following advantages:

•

•

Do not rely on functional T cells derived from the patient for clinical activity;

Display properties of both adaptive and innate immune systems and are capable of killing cells even if their specifically targeted CAR antigen is 
not present;

• Maintain the capacity to home to tissues and tumors rather than predominantly residing in circulation and can actively distribute into localized 

tumors; and

• May be less likely to induce cytokine release syndrome due to more limited endogenous IL-2 secretion by activated cells.

We  believe  these  advantages  position  gamma  delta  T  cell-based  therapies  to  become  an  attractive  to  bispecific-based  therapies  for  many  oncology 

indications and lines of therapy.

Our key anticipated differentiation from gamma delta T cell competitors

We believe that the gamma delta T cell technology that we are developing has a number of potential advantages over the technology of gamma delta T 

cell competitor companies, including the following:

•

•

•

•

Robust and practical proprietary antibody-based manufacturing method for gamma delta T cells

Large-scale expansion of blood-derived gamma delta T cells

Ability to selectively expand multiple gamma delta T cell subpopulations including highly potent Vδ1 cells

No potentially pro-tumorigenic Th17-type responses in our Vδ1 subpopulation

12

 
•

•

In-house CAR target identification and verification process

Ability to effectively target tumor-specific intracellular protein-derived peptides using proprietary TCRL antibodies

We  believe  these  advantages  position  our  gamma  delta  T  cell  based  therapies  to  become  an  attractive  approach  to  the  technologies  used  by  other 

gamma delta T cell competitor companies.

Production of gamma delta T cells

To  produce  gamma  delta  T  cell-based  product  candidates,  we  isolate  peripheral  blood  mononuclear  cells,  from  unrelated  donors  that  meet  all  the 
safety criteria for human cells, tissues, and cellular and tissue-based products (HCT/P), criteria for donors as outlined by the FDA in Title 21 of the Code of 
Federal Regulations (CFR), Part 1271. We then activate Vδ1 gamma delta T cells using a proprietary agonistic antibody and cytokines and expands these 
cells before introduction of replication-incompetent retroviral vectors containing the coding sequence for CAR constructs. These CAR-modified cells are 
further expanded, routinely greater than 6,000-fold at clinical scale, resulting in cell cultures that primarily consist of the desired gamma delta T cells. To 
reduce the chance of a patient developing GvHD, the remaining alpha beta T cells are then depleted using alpha-beta-specific, antibody-based techniques. 
The resulting gamma delta T cells are then formulated in an infusible solution to form the final drug product, which is filled into vials and then frozen to 
enable delivery of a post-thaw cell dose from each vial of CAR-T cells.

Figure 5. Production process for our CAR gamma delta T cell products.

Figure 6. Fold expansion of gamma delta T cells.

We  believe  that  our  manufacturing  process,  including  the  generation  of  the  antibodies  and  retroviral  vectors,  meets  current  Good  Manufacturing 
Practices  (cGMPs).  We  expect  to  be  able  to  produce  tens  to  hundreds  of  doses  from  a  single  donor,  greatly  increasing  the  efficiency  of  manufacturing 
compared  to  autologous  alpha  beta  T  cell  therapies.  We  have  chosen  to  partner  with  a  number  of  contract  manufacturing  organizations  (CMOs)  in  the 
United States and Europe to access specific capabilities to ensure that the manufacturing process is highly scalable, and fully cGMP-compliant.  We believe 
this process has the potential to treat up to 1,000 patients per batch.

ADI-001, an anti-CD20 CAR gamma delta T cell therapy targeting NHL

B cell NHL overview

NHL is the most common cancer of the lymphatic system. An estimated 77,240 new cases are expected to be diagnosed in the United States in 2020, 
according to the web site of the U.S. National Institutes of Health (NIH). According to the cancer.net web site maintained by the American Society for 
Clinical Oncology (ASCO), approximately 90% of NHL patients in western countries have B cell lymphomas of various types and DLBCL is the most 
common and aggressive type of NHL, accounting for 30% of NHL. The second most common type is follicular lymphoma (FL), which occurs in 20% of 
NHL patients. Mantle cell lymphoma (MCL), is diagnosed in 5% to 7% of NHL cases.

Although B cell NHLs represent a heterogeneous set of lymphomas, many cell surface antigens are shared among them, including CD19 and CD20. 
First line therapy for patients with aggressive B cell NHLs, such as DLBCL, is chemotherapy in combination with radiation or rituximab, an antibody that 
targets CD20. According to the rituximab label as published on the FDA web site, the addition of rituximab to chemotherapy results in an approximately 
10% to 15% overall increase in survival at one year compared to chemotherapy alone with almost no increase in toxicity. According to an article published 
by K.T. Godder et al. in the journal Bone Marrow Transplantation in 2007, up to 50% of patients become refractory or relapse after treatment. Of those, 
according to an article published by Andrew R. Rezvani and David G. Maloney in the journal Best Practice & Research Clinical Haematology in 2011, 
approximately  60%  percent  are  resistant  to  rituximab  upon  relapse.  Subsequent  chemotherapy-based  therapies  typically  have  limited  efficacy  in  these 
patients and, at that point, they become candidates for treatment with allogeneic HSCT or anti-CD19 CAR-T cell therapy. Approximately 35% of patients 
treated with anti-CD19 CAR-T cell therapies relapse within one year, according to the label for Kymriah® published on the Novartis web site.

Our solution, ADI-001

ADI-001 is a gamma delta T cell product candidate that targets malignant B-cells via an anti-CD20 CAR and via the gamma delta T cell endogenous 
receptors, which we are developing as an allogeneic immunocellular therapy for the treatment of B-cell NHL. ADI-001 is created from Vδ1 gamma delta T 
cells  isolated  from  unrelated  donors.  It  is  manufactured  in  bulk  under  cGMP-compliant  conditions  and  is  intended  to  be  supplied  as  an  immediately 
available off-the-shelf anti-CD20 CAR-T cell therapy.

ADI-001 contains an anti-CD20 CAR that has a proprietary antigen-binding domain that recognizes a region of CD20 distinct from that recognized by 
rituximab.  Similar  to  other  CAR-Ts  cells  including  the  one  used  to  create  Kymriah®,  our  CAR-T  cells  contain  the  clinically  validated  costimulatory 
domain from 4-1BB and the CD3ζ.

Clinical data

In October 2020, the FDA cleared our IND application for ADI-001 for the treatment of NHL. The active IND enabled us to initiate the first-in-human 
clinical trial to assess safety and efficacy of ADI-001 in NHL patients in the first quarter of 2021. The Phase 1 study for ADI-001 will enroll up to 80 late-
stage NHL patients at a number of cancer centers across the United States The study includes a dose finding portion followed by dose expansion cohorts to 
explore  the  activity  of  ADI-001  in  multiple  subtypes  of  NHL.  Included  in  this  trial  will  be  previously  treated  patients  who  were  not  able  to  receive 
approved  autologous  CAR-T  cell  therapies  due  to  medical,  technical,  logistical,  or  financial  reasons,  as  well  as  patients  who  relapsed  after  receiving 
autologous CAR-T cell therapies.  

Patients enrolled in the trial will undergo chemotherapy-based lymphodepletion for three days followed by ADI-001 dosing by infusion on day five. 
Patients  will  be  evaluated  at  four  weeks,  twelve  weeks  and  then  every  three  months  for  the  first  year  and  at  months  18  and  24  after  treatment.  Once  a 
recommended dose has been selected, up to 36 patients will be enrolled in indication-specific dose expansion cohorts: DLBCL, MCL, and one for all other 
B cell malignancies. Select patients experiencing clinical benefit with ADI-001 may be eligible for retreatment.

An additional cohort in this trial will investigate the potential of IL-2 therapy to boost the activity and durability of ADI-001. Treatment with IL-2 is 

supported by preclinical data that we have generated demonstrating that IL-2 improves the antitumor 

14

 
activity of our gamma delta T cells both in vitro and in vivo. Treatment of HSCT patients with IL-2 has also been shown to stimulate the proliferation of 
gamma delta T cells in the clinic.

(*)  Dose escalation study

Figure 7. Phase 1 ADI-001 study patient flow.

Phase 1 Interim Clinical Data

On December 6, 2021, we reported positive interim clinical data from the initial dose escalation portion of the Phase 1  study evaluating the safety and 
tolerability of ADI-001 in NHL that showed complete and near complete responses at low doses along with a generally favorable tolerability profile. We 
have since completed dosing of subjects in the second lowest dose level of our Phase 1 study and we are currently enrolling subjects in dose level three. We 
aim to provide a clinical update for ADI-001 in the first half of 2022. 

As of the November 22, 2021 data cutoff, six patients had been enrolled and received ADI-001. The first two patients enrolled in the lowest dose level 
tested  did  not  reach  the  day  28  assessment  and  were  not  evaluable  for  efficacy  per  protocol.    Three  of  the  four  evaluable  patients  achieved  responses, 
including two complete responses (CR) and one partial response (PR) that investigators characterized as near complete response. Patients were heavily pre-
treated, with a median of five lines of prior systemic therapy, including a patient who had received prior autologous CD19 CAR T, and achieved complete 
response following a single infusion of ADI-001 administered at the lowest dose level.

Of the four efficacy evaluable patients, three received ADI-001 at dose level one (30 million CAR+ cells) and one received ADI-001 at dose level two 
(100 million CAR+ cells). In dose level one, one patient achieved a CR, one patient achieved a PR that was characterized as near CR and one patient had 
progressive disease (PD). In dose level two, the first patient achieved a CR.

All evaluable patients had been heavily pre-treated with a median of five lines of prior systemic therapies. Of the three patients who achieved PR or 
better  under  Lugano  2014  criteria  (ORR=75%,  CR=50%),  one  had  FL  transformed  into  a  large  B-cell  tumor  with  four  prior  lines  of  therapy,  one  had 
DLBCL with five prior lines of therapy including two cycles of anti-CD19 CAR T cell therapy, and the third had MCL with five prior lines of therapy. 
These patients achieved two CRs and a near CR.

Overall,  ADI-001  infusions  were  generally  well-tolerated.  No  dose-limiting  toxicities  GvHD,  Immune  Effector  Cell-Associated  Neurotoxicity 
Syndrome (ICANS), Grade 3 or higher Cytokine Release Syndrome (CRS) have been reported to-date, suggesting a potentially wide therapeutic window 
for ADI-001.

A significant increase in circulating IL-15 was observed during the 28-day window following lymphodepletion, potentially providing cytokine support 
for  the  proliferation  of  ADI-001.  Emergence  of  circulating  ADI-001  in  the  blood  was  observed  by  quantitative  polymerase  chain  reaction  and  by  flow 
cytometry, demonstrating expansion of ADI-001 in patients. Elevations in additional circulating cytokines, primarily IL-2 and IL-8 were observed during 
the first 14 days from dosing, consistent with the activation profile of ADI-001 and similar to the observed time-to-peak for cytokines previously reported 
in association with autologous alpha-beta CAR T cells.  Importantly, no meaningful increases in IL-6 were seen in association with ADI-001, except for 
one patient who experienced COVID-19 infection, suggesting reduced likelihood for ICANS and high-grade CRS.

Preclinical data

All preclinical experiments were conducted using anti-CD20 CAR-modified gamma delta T cells, a research version of ADI-001. We evaluated the in 
vitro potency of our anti-CD20 CAR gamma delta T cells using human-derived laboratory cell lines, known as Raji and Daudi human Burkitt’s lymphoma 
cell lines, which are known to express high levels of CD20. Mixing the tumor cells with the anti-CD20 CAR gamma delta T cells resulted in apoptosis, or 
cell death, of the tumor cells after four hours. Increasing the ratio of the number of anti-CD20 CAR gamma delta T cells to tumor cells resulted in a higher 
percentage of dying tumor cells. Similar potency in the killing of target cells by anti CD20 CAR gamma delta T cells was observed in both Mino cells, a 
human  MCL  line  that  expresses  high  levels  of  CD20;  and  WILL-2  cells,  cells  derived  from  a  rituximab-resistant  patient  with  B  cell  lymphoma  that 
expresses low levels of CD20. These results suggest that anti-CD20 CAR gamma delta cells can be 

16

 
 
  
highly efficient at recognizing and eliminating tumor cells that express any level of CD20. In all cases, our gamma delta T cells that did not have anti-CD20 
CAR expression also caused tumor cell death due to innate cytotoxic receptors.

Figure 8. Anti-CD20 CAR gamma delta T cells demonstrated potent cell killing activity across multiple human tumor cell lines.

17

 
 
 
 
We have tested the antitumor activity of our anti-CD20 CAR gamma delta T cells in multiple tumor models in immunocompromised mice including 
Raji tumor models, a Mino tumor model and a Granta tumor model derived from a mantle cell tumor. Five to seven days after tumors were implanted into 
these mice, anti-CD20 CAR gamma delta T cells were administered as a single intravenous dose. Human recombinant IL-2 was administered three times a 
week for the duration of the study to stimulate the gamma delta T cells. In all cases, treatment using our anti-CD20 CAR gamma delta T cells was able to 
arrest tumor growth. The absolute duration of these studies was not pre-specified, however each of the studies were terminated when the growth of tumors 
in any of the animals in the no-treatment control group (tumor-only) exceeded a pre-specified limit; in subcutaneous tumor models this limit was generally 
tumor growth exceeding 4000mm3. This resulted in the individual studies being run for slightly different durations.

Figure 9. Anti-CD20 CAR gamma delta T cells inhibited tumor growth in multiple animal models.

Treatment of Raji tumors in mice with anti-CD20 CAR gamma delta T cells resulted in the complete elimination of tumors in four out of six mice. 
Sixty days after the original — and only – dose of anti-CD20 CAR gamma delta T cells, the four mice with complete responses were re-challenged with 
Raji tumor cells. Growth of these newly introduced tumors continued to be suppressed at least until the end of the experiment at day 100. We believe that 
these results suggest that our gamma delta cells 

18

 
 
 
 
had a long persistence in vivo and remain active. Other preclinical experiments have shown that they can undergo up to twenty cell doublings and can have 
antitumor activity that can extend to six months in animal models.

Figure 10. Gamma delta T cells retained their antitumor activity for at least 90 days in a Raji tumor model. Four of the six mice in the primary 
tumor challenge exhibited complete responses, and these four mice were given a second tumor challenge without additional gamma delta CAR T 
cells.

We performed a direct analysis of the ability of our gamma delta CAR-T cells to migrate and proliferate in tumors using a fluorescent dye technology 
to examine cell division. Gamma delta CAR-T cells were treated with a fluorescent dye that attaches to cellular proteins. As these fluorescent cells divided, 
the molecules modified with the fluorescent dye were split among the mother and daughter cells. This resulted in a reduction in the average fluorescence 
signal per cell. Quantification of the amount of fluorescence per cell was then used as a surrogate for the number of divisions that a cell has undergone.

Using  this  assay,  we  observed  that,  within  six  days,  our  CAR  gamma  delta  T  cells  had  undergone  significant  cell  divisions  in  tumors  with  little 
replication  in  blood,  spleen,  bone  marrow  or  liver.  By  contrast,  in  a  similar  experiment  using  CAR  alpha  beta  T  cells,  it  was  observed  that  replication 
occurred in all tissues examined. We believe that this selective replication in tumors by CAR gamma delta T cells, compared to CAR alpha beta T cells, 
may  contribute  to  increased  antitumor  activity  and  a  lower  risk  of  developing  life-threatening  systemic  immune  responses  such  as  cytokine  release 
syndrome.

Figure 11. Proliferation of CAR gamma delta T cells was primarily localized in tumors, while the proliferation of CAR alpha beta T cells was 
observed in all tissues examined.

Interleukin 15 (IL-15) is a cytokine that preferentially stimulates T cell and NK cell activation, proliferation and cytolytic activity. These functional 
activities of IL-15 translate to enhanced antitumor responses in multiple tumor models. IL-15 is closely related to a cytokine that is a known activator of 
immune  responses,  IL-2.  Both  cytokines  have  the  potential  to  stimulate  gamma  delta  T  cells.  IL-15  plays  a  more  important  role  in  maintaining  T  cell 
responses that are long-lasting and show high affinity for cancer cell targets, while IL-2 has a more significant role in activating cytotoxic responses.

The antitumor activity of our anti-CD20 CAR gamma delta T cells was tested in SRG-15 mice. These are mice that lack much of their mouse immune 
system but that do express human IL-15. In these studies, potent antitumor activity against Raji tumors in was observed. Furthermore, this activity was not 
accompanied by the development of GvHD. In contrast, mice treated with anti-CD20 CAR alpha beta T cells had antitumor responses, but subsequently 
experienced increased mortality due to the development of GvHD.

Figure 12. Anti-CD20 CAR gamma delta T cells do not induce GvHD, whereas treatment with anti-CD20 CAR alpha beta cells caused GvHD that 
led to increased mortality.

ADI-002, an anti-GPC3 CAR gamma delta T cell therapy for HCC

HCC disease background

Hepatocellular carcinoma (HCC) is the most prevalent form of liver cancer. The risk of HCC development is increased by a number of environmental 
and lifestyle factors such as hepatitis B and hepatitis C virus, alcohol drinking, tobacco smoking, aflatoxin exposure, obesity and diabetes. These factors 
lead to wide disparities in disease incidence across geographies. According to a 2013 publication by Sahil Mittal and Hashem B. El-Serag in the Journal of 
Clinical Gastroenterology, in the U.S., the incidence is approximately six per 100,000 per year, while in sub-Saharan Africa and Eastern Asia the incidence 
is over 20 per 100,000 per year.

Patients diagnosed with HCC generally have a poor prognosis. The majority of patients are diagnosed with advanced disease and they have a five-year 
survival rate of approximately 11%, according to cancer.net, the web site of ASCO. Patients are initially treated with combinations of cytotoxic drugs or 
radiation.  In  some  cases,  they  may  also  receive  targeted  therapies  including  kinase  inhibitors  such  as  lenvatinib,  marketed  as  Lenvima®  by  Eisai;  and 
sorafenib,  marketed  as  Nexavar®  by  Bayer  and  subsequently  cabozantinib,  marketed  as  Cabometyx®  by  Exelixis.  These  therapies,  however,  have 
significant  toxicities  and  limited  clinical  benefit  with  progression  free  survival  of  less  than  eight  months.  Checkpoint  immunotherapies  such  as 
pembrolizumab  and  nivolumab  have  demonstrated  some  efficacy  in  HCC,  although  response  rates  are  less  than  20%  according  to  the  label  for 
pembrolizumab,  marketed  by  Merck  as  Keytruda®.  The  combination  of  both  nivolumab  and  ipilimumab,  despite  increased  toxicities,  increased  this 
response  rate  to  33%.  We  believe  these  results  demonstrate  that  there  is  significant  unmet  need  in  HCC  and  that  there  is  potential  to  treat  HCC  with 
immunotherapy.

GPC3, a tumor-associated antigen

GPC3  is  a  tumor-associated  antigen  that  is  expressed  in  many  tumors  but  in  almost  no  normal  tissues  other  than  embryonic  liver  and  kidney  or 

placenta.

In a trial conducted by David Ho at the University of Hong Kong and colleagues and published in the journal PLOS One in 2012, high levels of GPC3 

are detected by immunohistochemistry in a large proportion of HCC tumor tissue samples, but no GPC3 can be detected in adjacent normal cells.

Our solution, ADI-002

ADI-002  is  an  anti-GPC3  CAR  gamma  delta  T  cell  product  candidate  that  we  are  developing  for  the  treatment  of  solid  tumors.  We  believe  that 
modification of Vγ1 gamma delta T cells, which have an inherent tumor homing ability, with a CAR that is specific for GPC3, may result in a therapeutic 
product able to have potent antitumor activity in patients suffering from multiple solid tumors. On January 28, 2022, Regeneron exercised its option to 
license the exclusive, worldwide rights to ADI-002 pursuant to our agreement signed in 2016. In conjunction with the exercise of its option, Regeneron 
paid us an exercise fee of $20.0 million. We elected not to exercise our option to co-fund the further development of ADI-002. Accordingly, Regeneron is 
responsible, at its sole cost, for all development, manufacturing and commercialization of ADI-002 and we are entitled to royalties of any future sales of 
such products by Regeneron. See the section titled “Business—Strategic Agreements” of this Annual Report on Form 10-K. 

To enhance the proliferative ability and durability of our anti-GPC3 CAR gamma delta T cells, we engineered these cells to express soluble IL-15. We 

anticipate that the tumor homing ability of gamma delta T cells will potentially result in expression

of IL-15 predominantly in tumors. In combination with the inherent secretion of factors such as interferon gamma from activated gamma delta T cells, the 
secretion of IL-15 is anticipated to lead to reversal of immunosuppressive effects in the tumor microenvironment and direct stimulation of the gamma delta 
T cells.

We demonstrated in in vitro assays that our anti-GPC3 CAR gamma delta T cells have potent and GPC3-antigen-dependent cell killing activity. When 
our anti-GPC3 CAR-T cells were added to HepG2 cells, a cell line expressing GPC3 that was derived from a patient with HCC, an increase in tumor cell 
killing  was  observed.  Gamma  delta  T  cells  prepared  without  the  addition  of  our  anti-GPC3  CAR  were  still  able  to  kill  the  HepG2  cells,  only  with  less 
potency at 18 hours. We believe that this CAR-independent killing activity was driven by innate receptors on our gamma delta T cells and that this innate 
antitumor activity may provide meaningful antitumor clinical activity in cases in which tumors may lose the expression of the targeted GPC3 antigen. Loss 
of tumor-expressed antigens represents a significant mechanism of escape from antitumor activities from other immunotherapies such as anti-CD19 CAR-T 
cell  therapies.  The  ability  to  continue  to  have  antitumor  activity  driven  by  the  innate  immune  cell  properties  of  our  gamma  delta  T  cells  is  a  distinct 
advantage compared to alpha beta T cells, which lack this capability. Our gamma delta T cells had no cell killing activity when added to RAT2 normal 
fibroblasts that do not express GPC3.

Figure 15. Expression of an anti-GPC3 CAR in gamma delta T cells led to potentiation of killing of HepG2 hepatocellular carcinoma cell line.

Anti-GPC3 CAR gamma delta T cells had dose-dependent antitumor activity in HepG2 tumors in immunodeficient mice. HepG2 tumor cells were 
inoculated into immunocompromised mice and allowed to grow to a volume of 200 mm3 over a period of approximately eight days. A single dose of anti-
GPC3 CAR gamma delta T cells was then administered and tumor growth at day 37 was assessed. High doses of anti-GPC3 gamma delta T cells led to 
complete suppression of tumor growth.

Future clinical candidates in solid tumors.

In  addition  to  the  product  candidates  described  above,  we  anticipate  many  further  opportunities  for  developing  product  candidates  based  on  our 
gamma delta T cell technology. We believe that the spectrum of indications that products such as CAR-T cell therapies have been able to address has been 
limited by two factors: the weak ability of alpha beta T cell-based therapies to penetrate solid tumors, and the scarcity of tumor-specific antigens on the cell 
surface that can be targeted by antibody-derived binding domains that are an essential component of the CAR constructs. We believe that the tumor homing 
ability of our gamma delta T cell technology represents a potential solution to the solid tumor localization problem and our TCRL antibody technology can 
be used to identify and target tumor-specific antigens.

The tumor recognition challenge

Therapeutics such as antibodies and CARs recognize cell surface molecules. In HCC and select other tumors, there are proteins such as GPC3 which 
are selectively expressed on the surface of tumors cells that can be used as antigens for immune-targeted therapy. The lack of their expression on normal 
cells limits the potential of on-target, off-tumor systemic toxicities. Surface-expressed proteins that are strictly expressed only on tumor cells are, however, 
rare. In most cases surface expressed antigens such as CD19 and CD20 are expressed both on hematopoietic tumor and normal cells. Therapies that target 
CD19 or CD20 therefore result in killing of both tumor and normal cells. In hematological malignancies these therapies result in systemic depletion of 
normal B cells. However, this is mechanism-based toxicity can be managed in clinical practice. Challenges arise with antigens such as epidermal growth 
factor receptor (EGFR) that is overexpressed on some types of tumor cells, but also expressed on normal epithelial cells elsewhere in the body. Dosing with 
anti-EGFR antibodies has led to significant dermatological and cardiac toxicities.

Intracellular  proteins  represent  nearly  half  of  the  proteins  found  in  human  cells.  These  proteins  provide  an  untapped  reservoir  of  potential  tumor-
specific antigens that are inaccessible to traditional antibody-binding domains. Immune surveillance for these intracellular proteins is normally done by 
alpha beta T cells. These intracellular proteins are chopped up by a cell component known as the proteasome into short peptides between eight and ten 
amino acids long. These short peptides are then presented to the T cells by the MHC. TCRs on the T cells are then able to recognize the complex of the 
peptide and the MHC, triggering creation of T cell populations prepared to attack these specific sequences.

Gamma delta T cells have advantages compared to alpha beta T cells with regard to their potential as allogeneic therapies, their ability to localize to 
tumors and their retention of innate immune signaling pathways. However, to be most effective they need to be able to be engineered to attack specific 
tumors.

Our solution, TCRLs

We have developed an antibody platform that enables the discovery of TCRL antibodies that recognize peptides that are presented on the cell surface 
by specific MHC molecules. In effect, our TCRL antibodies have the same antigen recognition properties as TCRs but are highly specific for a single tumor 
antigen and MHC molecule. They do not recognize other MHC molecules or antigens that may be expressed by healthy cells.

Figure 17. Schematic diagram of the interaction between our TCRL antibodies and tumor-specific peptides presented by the MHC.

23

 
  
 
 
TCRLs  are  conventional  antibodies  with  antigen  binding  domains  that  specifically  recognize  peptide-MHC  complexes  that  can  be  used  to  create 
CARs. Introduction of these CARs into our gamma delta T cells enables them to target tumors expressing intracellular tumor antigens when these antigens 
are selectively presented by MHC on the surface of tumor cells. Gamma delta CAR-T cells generated using TCRLs open up the potential to bring immune 
cell therapy to tumors that lack tumor-specific surface antigens, a group that includes most solid tumors.

The  TCRL  discovery  process  starts  by  carrying  out  an  analysis  of  the  peptides  expressed  by  MHC  receptors  in  a  panel  of  hundreds  of  tumor  and 
normal  tissues.  In  searching  for  candidate  peptides,  we  focus  on  differentially  expressed  peptides  that  are  broadly  expressed  in  tumors  but  that  are  not 
found in normal tissues. Candidate peptides are then validated by expression analysis both in other tissues as well as in databases. Those peptides that, 
based on bioinformatic analysis, are predicted to have minimal cross-reactivity with peptides from normal cells are then further prioritized. This peptide 
discovery process leads, step-by-step, to the narrowing of the list of potential candidates by approximately one thousand-fold. Once a tractable number of 
remaining candidates has been identified, a population that includes the most promising ones, antibodies are then created that are specific to the complex of 
an  MHC  receptor  and  the  bound  peptides.  These  antibodies  mimic  key  aspects  of  tumor  as  recognized  by  the  immune  system.  By  creating  CARs  that 
incorporate  these  antigen-recognition  templates  in  gamma  delta  T  cell-based  product  candidates,  we  create  a  set  of  candidates  designed  to  specifically 
attack tumors by virtue of their intracellular proteins.

Tyrosinase is a well-validated tumor-expressed antigen for which we have developed TCRLs. The specificity for a mouse and a humanized version of 
one of these TCRLs was determined by comparing their binding affinity to that of a series of peptides that contained single amino acid changes. It was 
learned that changes to any of the internal eight amino acid positions to the amino acid alanine led to reductions in binding of 70% or greater. Substituting 
any amino acid in a non-anchor position resulted in substantial loss of binding and indicates the high degree of specificity that the TCRL antibody has for 
the targeted MHC peptide complex.

Figure 18. Single amino acid changes to the targeted peptide reduced binding by at least 70 percent.

The antigen-binding domain from a tyrosinase TCRL was incorporated into a CAR and introduced into our gamma delta T cells to assess cell killing 
activity against tumor cell lines. These anti-Tyr CAR gamma delta T cells led to cell killing of WM266.4 human metastatic melanoma tumor cells, which 
are known to express tyrosinase. Anti-Tyr CAR gamma delta T cells, however, had no cell killing activity when tested against ten other cell lines from 
tumors such as colon, bladder and pancreatic cancers, B cell leukemia and retinoblastoma – all of which do not express tyrosinase. That observation points 
to a desirable level of specificity for our anti-Tyr CAR gamma delta T cells and to an important in vitro proof of concept.

Furthermore, these anti-Tyr CAR gamma delta T cells had potent antitumor activity in a WM266.4 tumor model leading to tumor shrinkage within 

five days of administration and a durable antitumor response through 27 days. Although the TCRL-based 

24

 
  
 
 
CAR that is generated binds to an MHC-peptide complex, it does not induce the GvHD that is seen with alpha beta T cells because it recognizes a single 
peptide that has been selected to be highly specific for tumor cells.

Figure 19. Anti-Tyr CAR gamma delta T cells showed potent antitumor activity in a WM266.4 melanoma model.

We have generated TCRLs against a number of solid tumor antigens which are being evaluating in animal models. We believe that the combination of 
our gamma delta and TCRL technology provides the basis for a new generation of CAR-T cell therapies that have the potential to transform the treatment 
of solid tumors.

Our Intellectual Property

Our gamma delta T cell-based product candidates and substantially all of our intellectual property have been developed by us, with certain antigen 
binding domains derived from our collaboration with Regeneron. Additional intellectual portfolio assets were acquired in 2016 via acquisition of Applied 
Immune  Technologies  Ltd.  (AIT),  which  is  now  our  wholly  owned  subsidiary,  Adicet  Bio  Israel,  Ltd.  We  strive  to  protect  and  enhance  the  proprietary 
technology, inventions and improvements that are commercially material to our business, including seeking, maintaining and defending our patent rights.

Our policy is to develop and maintain protection of our proprietary position by, among other methods, filing or in-licensing United States and foreign 
patents and applications related to our technology, inventions, and improvements that are material 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.

Our patent portfolio includes protection for our lead product candidates, ADI-001 and ADI-002, as well as our other research-stage candidates. As of 
February  23,  2022,  there  are  multiple  patent  families  comprising  three  pending  United  States  non-provisional  applications  and  over  30  corresponding 
foreign  patent  applications  pending  in  such  jurisdictions  as  Australia,  Canada,  China,  Europe,  Japan,  Russia,  and  South  Africa  with  claims  directed  to 
reagents and related protocols for gamma delta T cell expansion and resulting compositions of matter encompassing both ADI-001 and ADI-002, which, if 
issued,  are  expected  to  expire  between  2035  and  2038.  The  first  U.S.  non-provisional  application  in  our  original  patent  family  recently  granted  as  U.S. 
Patent No. 11,135,245, expiring on May 19, 2038, and the pending U.S. non-provisional application in our second patent family stands allowed.  As of 
February  23,  2022,  there  are  also  two  patent  families  comprising  two  U.S.  non-provisional  applications    and  over  25  corresponding  foreign  patent 
applications pending in such jurisdictions as Australia, Canada, China, Europe, Israel, Japan, South Korea, Mexico, New Zealand, Russia, Singapore and 
South Africa , with claims directed to CAR constructs and antigen binding domains relating to ADI-001 and ADI-002, as well as their methods of use for 
certain  indications,  preconditioning  methods,  and  dosing  regimens,  where  applications  claiming  the  benefit  of  these  PCT  applications,  if  issued,  would 
expire between 2038 and 2039. Additionally, we have one pending U.S. provisional application directed to certain methods of treatment using ADI-001, 
and another pending U.S. provisional application directed to certain proprietary antibodies to GPC3 and methods of use thereof. With respect to ADI-001, 
we  have  a  collaboration  with  Regeneron  which  grants  us  access  to  certain  proprietary  antigen  binding  domains  covered  by  Regeneron’s  patent  rights, 
including in particular the antigen binding domain incorporated into ADI-001. 

Additionally, there are multiple granted patents and pending patent applications in the United States and internationally directed to our TCRL platform 
technology,  with  actual  and,  in  the  case  of  pending  applications,  anticipated  expiration  dates  between  2021  and  2037.  Although  certain  earlier  patents 
relating to our TCRL platform technology will expire in 2021, other patents covering this technology remain in force, or are expected to issue from pending 
applications,  including  three  pending  patent  families  directed  to  certain  carcinoma,  melanoma  and  glioblastoma  targets,  are  expected  to  expire  between 
2036 and 2037. As a result, we do not expect that the expiration of the earlier patents in our TCRL portfolio, individually or in the aggregate, will have a 
material adverse effect on our future operations or financial position.

25

 
 
 
 
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 U.S., 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 U.S., 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.

Our  commercial  success  depends  in  part  on  our  ability  to  obtain  and  maintain  proprietary  protection  for  our  product  candidates,  as  well  as  novel 
discoveries, core technologies, and know-how, as well as our ability to operate without infringing on the proprietary rights of others and to prevent others 
from infringing our proprietary rights.

The  patent  positions  of  companies  like  us  are  generally  uncertain  and  involve  complex  legal,  scientific,  and  factual  questions.  In  addition,  the 
coverage  claimed  in  a  patent  application  can  be  significantly  reduced  before  the  patent  is  issued,  and  its  scope  can  be  reinterpreted  after  issuance. 
Consequently,  we  do  not  know  whether  any  of  our  product  candidates  will  be  protectable  or  remain  protected  by  enforceable  patents  or  will  be 
commercially useful in protecting our commercial products and methods of using and manufacturing the same. We also cannot predict whether the patent 
applications it is currently pursuing will issue as patents in any particular jurisdiction or whether the claims of any issued patents will provide sufficient 
proprietary protection from competitors. Any patents that we hold or control may be challenged, circumvented or invalidated by third parties. In addition, 
while we have confidence in our agreements and security measures, either may be breached, and we may not have adequate remedies. Further, our trade 
secrets may otherwise become known or independently discovered by competitors.

We have licensed various intellectual property and trade secrets to third parties for purposes of collaboration, product development and research and 

development.

Strategic Agreements

License and Collaboration Agreement with Regeneron

On July 29, 2016, our wholly owned subsidiary, Adicet Therapeutics, Inc. (Former Adicet), entered into a license and collaboration agreement with 
Regeneron, which was amended in April 2019, with such amendment becoming effective in connection with Regeneron’s investment in Former Adicet's 
Series B preferred stock financing transaction in July 2019 (as amended, referred to as the Regeneron Agreement) when Former Adicet was an early-stage, 
privately held company.

Agreement Structure. The Regeneron Agreement has two principal components: (a) a research collaboration component under which the parties will 
research, develop, and commercialize next-generation engineered gamma delta immune cell therapeutics (ICPs) namely engineered gamma delta immune 
cells with CARs and TCRs directed to disease-specific cell surface antigens, which includes the grant of certain licenses to intellectual property between 
the  two  parties,  and  (b)  for  a  certain  period  following  the  effective  date,  a  license  to  us  to  use  certain  of  Regeneron’s  proprietary  mice  to  develop  and 
commercialize ICPs generated by us, with certain limitations relating to targets under the Regeneron Agreement.

Research Collaboration. Research activities under the collaboration are governed by research plans, which include the strategy, goals, activities, and 
responsibilities of the parties with respect to a target. We are primarily responsible for generating, validating, and optimizing ICPs, developing processes 
for manufacture of ICPs, and certain preclinical and clinical manufacturing activities for ICP’s; Regeneron’s key responsibility is generating, validating, 
and optimizing CARs and TCRs that bind to the applicable target. The parties have formed a joint research committee to monitor and govern the research 
and development efforts during the research program term.

Rights to Research Targets. Under the terms of the collaboration, the parties will conduct research on mutually agreed upon targets. Regeneron may 
obtain  exclusive  rights  for  the  targets  that  it  chooses  in  accordance  with  the  target  selection  mechanism  set  forth  in  the  Regeneron  Agreement,  and  we 
similarly  may  obtain  exclusive  rights  for  targets  it  chooses  in  accordance  with  such  target  selection  mechanism.  We  have  the  right  to  develop  and 
commercialize ICPs to the first collaboration target to come out of the research program. On January 28, 2022, we received a payment of $20 million from 
Regeneron for exercise of its option to license exclusive rights to ADI-002 and Regeneron potentially has additional options to other ICP targets under the 
Regeneron Agreement. For those targets it does not have an option to license, Regeneron has a right of first negotiation for up to two targets. Regeneron 
has the right to terminate the research program in its entirety (a) for convenience on six months prior written notice given at any time after December 31, 
2019, or (b) following a change of control (as defined in the Regeneron Agreement) of us. The parties mutually agreed to their first product declaration 
criteria for collaboration ICP, CD20, in 2018.

26

 
Rights  to  Adicet-Developed  Targets.  Regeneron  has  an  exclusive  license  to  use  targeting  moieties  generated  by  us  by  its  use  of  Regeneron’s 

proprietary mice to develop and commercialize non-ICPs.

Exclusivity. During the five-year target selection period that expired in July 2021, we were not permitted to directly or indirectly research, develop, 
manufacture or commercialize an ICP, or grant a license to do the foregoing, except pursuant to the Regeneron Agreement. For so long as either party is 
researching or developing an ICP to a target under the research program, neither party may research, develop, manufacture or commercialize any other ICP 
to  such  target,  or  grant  a  license  to  do  the  foregoing.  And  for  so  long  as  a  party  is  researching,  developing  or  commercializing  an  ICP  to  target  that  is 
licensed to it (and royalty bearing) under the agreement, neither party may research, develop, manufacture or commercialize any other ICP to such target, 
or grant a license to permit another party to do the foregoing. These exclusivity obligations are limited to engineered gamma delta immune cells to targets 
reasonably considered to have therapeutic relevance in oncology. The Regeneron Agreement includes certain exceptions to the exclusivity obligations of 
the parties, including with respect to targets that are rejected by one party in the target selection process, as well as protections in the event of a change of 
control of a party where the acquirer has a competing program.

Co-Funding and Profit Sharing. We have an option to co-fund specified portions of the future development costs for, and to co-promote, ICPs to a 
target  for  which  Regeneron  has  exercised  an  option,  and  to  participate  in  the  profits  for  such  target.  We  have  the  right  to  exercise  this  right  in  various 
geographic  regions,  including  on  a  worldwide  basis.  In  the  event  we  exercise  such  right,  the  parties  will  share  further  development  costs  and  profits 
proportionally to their co-funding percentages.

Financial Terms. We received a non-refundable upfront payment of $25.0 million from Regeneron upon execution of the Regeneron Agreement and 
received an aggregate of $20.0 million of additional payments for research funding from Regeneron as of December 31, 2021. On January 28, 2022, we 
received payment of $20.0 million from Regeneron for exercise of its option to license exclusive rights to ADI-002. Regeneron has additional options to 
other ICP targets under the Regeneron Agreement which may entitle us to exercise fees of up to an aggregate of $80.0 million. For each collaboration ICP, 
we have a specified period of time to elect to co-fund the future development costs and participate in any potential profits with Regeneron up to a specified 
co-funding percentage in various geographic regions. If we do not exercise our right to co-fund the development of such collaboration ICPs, Regeneron 
must also pay us high single digit royalties as a percentage of net sales for ICPs to targets for which it has exclusive rights, and low single digit royalties as 
a  percentage  of  net  sales  on  any  non-ICP  product  comprising  a  targeting  moiety  generated  by  us  through  the  use  of  Regeneron’s  proprietary  mice.  We 
elected not to exercise our option to co-fund the development of ADI-002. Additionally, under the Regeneron Agreement, we must pay Regeneron mid-
single to low double digit, but less than teens, of royalties as a percentage of net sales of ICPs to targets for which we have exercised exclusive rights, and 
low  to  mid-single  digit  of  royalties  as  a  percentage  of  net  sales  of  targeting  moieties  generated  from  our  license  to  use  Regeneron’s  proprietary  mice. 
Royalties are payable until the longer of the expiration or invalidity of the licensed patent rights or twelve (12) years from first commercial sale.

Other  Terms.  The  Regeneron  Agreement  contains  customary  representations,  warranties  and  covenants  by  us  and  Regeneron  and  includes  (i)  an 
obligation of ours to use commercially reasonable efforts to develop and commercialize at least one product based on a collaboration ICP that is not an 
optioned  collaboration  ICP  for  each  collaboration  target  and  (ii)  an  obligation  of  Regeneron  to  use  commercially  reasonable  efforts  to  develop  and 
commercialize at least one product based on an optioned collaboration ICP for each collaboration target. We and Regeneron are required to indemnify the 
other party against all losses and expenses related to breaches of the representations, warranties and covenants under the Regeneron Agreement.

Term  and  Termination.  The  term  of  the  Regeneron  Agreement  expires,  on  a  product-by-product  basis,  on  the  expiration  of  the  obligation  to  pay 
royalties for such product. The Regeneron Agreement is subject to early termination by either party upon uncured material breach by the other party. The 
licenses to develop and commercialize an ICP to a target that one party has exclusively licensed may be terminated by such party for convenience.

Equity  Investments.  In  connection  with  the  collaboration,  Regeneron  and  we  entered  into  a  side  letter  pursuant  to  which,  among  other  matters, 
Regeneron  was  granted  certain  stockholder  rights  and  investment  rights  in  connection  with  our  next  equity  financing  that  met  certain  criteria  and  in 
connection  with  an  initial  public  offering  by  us.  Regeneron  exercised  its  investment  right  and  purchased  approximately  $10.0  million  of  our  Series  B 
preferred stock in a private placement transaction in July 2019.

License Agreement with TRDF

We and our wholly owned subsidiary, Adicet Bio Israel, Ltd. (formerly AIT), are parties to an Amended and Restated License Agreement dated May 
21, 2014, as was amended in June 2015 and January 2016, with Technion Research and Development Foundation Ltd. (TRDF) the technology transfer 
subsidiary  of  Technion  –  Israel  Institute  of  Technology  (Technion).  The  license  agreement  provides  us  with  an  exclusive,  royalty-bearing,  worldwide 
license, with a right to grant sublicenses, to make use of certain TRDF patents and know-how relating to moieties that recognize and bind to TCRLs, along 
with certain improvements and research results developed at TRDF and relating to either the licensed patents and know-how of TCRL, in each case for the 
purposes  of  research,  development,  and  commercialization  of  specified  products.  We  further  obtained  joint  ownership  rights  in  improvements, 
developments, and inventions developed in the laboratory of a specified professor under certain conditions, including where we provided specified amounts 
of funding for research specific to TCRL compounds. TRDF 

27

 
also  grants  us  an  exclusive,  worldwide,  assignable,  sublicensable  license  to  TRDF’s  rights  in  such  jointly  owned  improvements,  developments,  and 
inventions. Technion further agrees not to enforce against us any TCRL-related technology owned by Technion but not licensed to us under the agreement, 
and to require its licensees to agree to the same. We are required to meet certain diligence obligations to preserve our exclusive licenses. Either Adicet or 
Technion may terminate the agreement or a specific license if the other party materially breaches its obligations under the agreement or with respect to a 
specific license granted under it and fails to cure that breach. We have the right to terminate the agreement at any time by providing notice to TRDF.

In return for the license, We are required to pay TRDF, for ten (10) years after the first commercial sale of a product for which it owes royalties under 
the agreement, on a licensed-product-by-licensed-product basis, (i) certain royalties in the low single-digit percentages of all net sales by us and any of our 
controlled affiliates, and (ii) the lesser of (a) a low single-digit percentage of net sales of our sublicensees, or (b) low double-digit percentage of amounts 
received by us or our controlled affiliates in the form of royalties on net sales from our sublicensees, subject to certain reductions. Furthermore, we agreed 
to pay for all patent filing and maintenance expenses for the patents included in the licenses granted to us by TRDF, with limited exceptions.

Under the agreement, TRDF reserves the right, for itself, alone or with other certain academic institutions, to utilize the licensed technology solely for 

educational and non-commercial research purposes.

The  license  agreement  continues  in  full  force  and  effect  on  a  product-by-product  and  country-by-country  basis  until  the  expiration  of  all  payment 
obligations for any licensed product as described above. Upon the expiration, we will have a fully paid-up, worldwide, non-exclusive license (with the right 
to grant sublicenses) to develop, have developed, manufacture, have manufactured, use, market, offer for sale, sell, have sold, import, export, and otherwise 
transfer physical possession or title to products for which royalties would have otherwise been due under the agreement.

Manufacturing

We  are  developing  and  enabling  scalable  and  propriety  cGMP-compliant  manufacturing  processes.  We  have  invested  resources  to  optimize  our 

manufacturing process and plans to continue to invest to continuously improve our production and supply chain capabilities over time.

We  manufacture  cell-based  immunotherapy  products  based  on  gamma  delta  T  cells  obtained  from  the  blood  of  donors  who  are  unrelated  to  the 
patients that will be treated. These products are classed as allogeneic cell therapy products. Donor-derived blood is fractionated and the fractions containing 
gamma delta T cells are frozen prior to use in future manufacturing campaigns. We believe that our freezing and storing of the donor blood products allows 
us to efficiently schedule subsequent manufacturing steps. After obtaining blood products from unrelated donors the manufacturing process begins with the 
activation of a subpopulation of gamma delta T cells using an antibody that is proprietary to us. This antibody, in combination with other factors including 
the cytokine, IL-2, induces gamma delta T cells to proliferate, whereupon we expose the cells to a viral vector that transfers a gene sequence encoding a 
CAR, or other gene sequences, to the proliferating cells. This step is referred to as the transduction step. Following the transduction step gamma delta T 
cells are induced to proliferate further with IL-2 before an enrichment step that increases the proportion of gamma delta T cells, removes unwanted residual 
alpha beta T cells and results in the CAR-modified gamma delta T cells drug product. CAR-modified gamma delta T cell products are then frozen in single-
use  vials  for  long-term  storage  at  cryogenic  temperatures.  These  storage  conditions  are  designed  to  ensure  stability  of  the  cell-based  drug  products  for 
protracted periods of time. The storage in singe use vials is designed to simplify the handling and treatment administration. Just prior to administration of 
treatment, the vials will be thawed and then the contents infused into the patient. We believe that the single manufacturing process we are developing will 
be able to be completed in approximately two weeks and will result in sufficient quantities of drug product to treat numerous patients.

To date, we currently rely, and expects to continue to rely, on third parties for the manufacture of our product candidates and any products that we may 
develop. We have chosen to partner with a number of CMOs in the United States and Europe to access specific capabilities to ensure that the manufacturing 
process is highly scalable, closed and fully cGMP compliant. This strategy allows us to maintain a more flexible infrastructure while focusing our expertise 
on  developing  our  products.  In  addition  to  the  quality  management  systems  utilized  by  strategic  manufacturing  partners,  we  have  established  a  quality 
control and quality assurance program, which includes a set of standard operating procedures and specifications designed to ensure that our products are 
manufactured in accordance with cGMPs, and other applicable domestic and foreign regulations.

For example, we currently engage a single US-based third-party manufacturer to provide the active pharmaceutical ingredient for ADI-001. We also 
utilize separate third party contractors to manufacture cGMP-compliant starting and critical materials that are used for the manufacturing of our product 
candidates, such as donor blood products, gamma delta T cell activating antibody and 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 gamma delta T cell product are available 
from  qualified  suppliers  and  suitable  for  pivotal  process  development  in  readiness  for  registration  and  commercialization.  Going  forward,  we  intend  to 
continue to expand our manufacturing capability through agreements with leading cell therapy CMOs.

28

 
If any of our current manufacturers becomes unavailable to us for any reason, we believe that there are a number of potential replacements, although 
we  would  likely  incur  some  delay  in  identifying  and  qualifying  such  replacements.  We  plan  to  continue  to  create  a  robust  supply  chain  with  redundant 
sources of supply comprised of both internal and external infrastructure.

Competition

The pharmaceutical and biotechnology industries are characterized by rapidly advancing technologies, intense competition and a strong emphasis on 
proprietary products. We face potential competition from many different sources, including existing and 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 Pharma (now Gilead) were the first to achieve FDA approval for autologous T cell therapies. In August 2017, Novartis obtained 
FDA  approval  to  commercialize  Kymriah®,  for  the  treatment  of  children  and  young  adults  with  B-cell  acute  lymphoblastic  leukemia  (ALL)  that  is 
refractory  or  has  relapsed  at  least  twice.  In  May  2018,  Kymriah®  received  FDA  approval  for  adults  with  relapsed  or  refractory  (R/R)  large  B-cell 
lymphoma. In October 2017, Kite Pharma 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. In July 2020, Gilead obtained FDA approval to commercialize Tecartus™, the first CAR T cell product 
candidate for the treatment of adult patients with R/R MCL. In February 2021, Bristol Myers Squibb obtained FDA approval to commercialize Breyanzi® 
for the treatment of adults 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 generally. Potential T cell therapy competitors include, but are not 
limited to:

•

•

Allogeneic  T  cell  therapy  competition:  Atara  Biotherapeutics,  Inc.,  Allogene  Therapeutics,  Inc.,  Cellectis,  S.A.,  Celyad  S.A.,  CRISPR 
Therapeutics  AG,  Editas  Medicine,  Inc.,  Fate  Therapeutics  Inc.,  Gilead  Sciences,  Inc.,  Intellia  Therapeutics,  Inc.,  Poseida  Therapeutics,  Inc., 
Precision Biosciences, Inc., Immatics Biotechnologies GmbH, GammaDelta Therapeutics Limited, TC BioPharm Limited, Incysus Therapeutics, 
Inc. and Gadeta BV.

Autologous  T  cell  therapy competition:  Adaptimmune  Therapeutics  PLC,  Autolus  Therapeutics  plc,  bluebird  bio,  Inc.,  Bristol-Myers  Squibb 
Company,  Gilead  Sciences,  Inc.,  Johnson  &  Johnson,  Iovance  Biotherapeutics,  Inc.,  Mustang  Bio,  Inc.,  Novartis  International  AG,  TCR² 
Therapeutics Inc. and Tmunity Therapeutics, Inc.

Although we believe our development of proprietary processes for engineering and manufacturing gamma delta T cells expressing CARs is unique 
due to what we believe is the enormous potential of these cells, it is likely that additional competition may arise from existing companies currently focusing 
on development of alpha beta or gamma delta T cell therapies, or from new entrants in the field.

Competition may also arise from non-cell based immune oncology platforms. For instance, we may experience competition from companies, such as 
Amgen Inc., Bristol-Myers Squibb Company, F. Hoffmann-La Roche AG, Genmab A/S, GlaxoSmithKline plc, MacroGenics, Inc., Merus N.V., Regeneron 
Pharmaceuticals, Inc., and Xencor Inc., 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., AbbVie, Daiichi Sankyo Company, Limited, GlaxoSmithKline plc, ImmunoGen, Inc., Immunomedics, Inc., 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, preclinical 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  our  own  products,  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  tolerability  profile,  convenience,  price,  reimbursement  and  cost  of 
manufacturing.

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

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

Government Regulation and Product Approval

As  a  biopharmaceutical  company  that  operates  in  the  United  States,  we  are  subject  to  extensive  regulation.  Our  cell  products  will  be  regulated  as 
biologics. With this classification, commercial production of our products will need to occur in registered facilities in compliance with cGMP for biologics. 
The FDA categorizes human cell- or tissue-based products as either minimally manipulated or more than minimally manipulated and has determined that 
more  than  minimally  manipulated  products  require  clinical  trials  to  demonstrate  product  safety  and  efficacy  and  the  submission  of  a  Biologics  License 
Application (BLA) to the FDA 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.  Generally,  before  a  new  drug  or  biologic  can  be  marketed, 
considerable data demonstrating our quality, safety and efficacy must be obtained, organized into a format specific for each regulatory authority, submitted 
for review and approved by the regulatory authority.

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 U.S., 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.

United States Product Development Process

In the U.S., the FDA regulates pharmaceutical and biological products under the Federal Food, Drug and Cosmetic Act (the FDCA), the Public Health 
Service  Act  (the  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 United States 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 key animal studies according to good laboratory practices (GLPs), and applicable requirements for 
the humane use of laboratory animals or other applicable regulations;

submission to the FDA of an IND application, which is subject to a waiting period of thirty (30) calendar days, must become effective before 
human clinical trials may begin;

approval by an independent Institutional Review Board (IRB) or ethics committee for 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 our 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

30

 
•

FDA review and approval, or licensure, of the BLA prior to any commercial marketing or sale of the biologic in the U.S.

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  key  preclinical  tests  must  comply  with  federal 
regulations and requirements including GLPs. An IND is a request for authorization from the FDA to administer an investigational product to humans and 
must  become  effective  before  human  clinical  trials  may  begin.  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 thirty (30) days after receipt by the FDA, unless 
the FDA raises concerns or questions regarding the proposed clinical trials and requests additional information and or 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 at independent 
clinical sites/hospitals, 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 institutional review board (IRB) at or servicing each institution at which the clinical trial will be conducted. An 
IRB is charged with protecting the welfare and rights of 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. 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.

A sponsor who wishes to conduct a clinical trial outside of the United States may, but need not, obtain FDA authorization to conduct the clinical trial 
under an IND. If a foreign clinical trial is not conducted under an IND, the sponsor may submit data from the clinical trial to the FDA in support of a BLA. 
A clinical trial outside the United States may also be conducted under the authorization of similar regulatory authorities of the country/region. The FDA 
will accept a well-designed and well-conducted foreign clinical study not conducted under an IND if the study was conducted in accordance with GCP 
requirements, and the FDA is able to validate the data through an onsite inspection if deemed necessary.

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

•

•

•

Phase 1. The biological product is typically introduced into healthy human subjects and tested for safety. However, in the case of some products 
for severe or life-threatening diseases, such as cancer or the hematological malignancies that we aspire to treat, initial human testing is routinely 
conducted directly in ill patients with the approval of relevant ethics committee(s) under the supervision of a licensed physician.

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. In 
case of an accelerated BLA approval based on limited clinical data, FDA may mandate a Phase 4 clinical trial prior to full approval. 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 

31

 
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 fifteen (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  (7) 
calendar days after the sponsor’s initial receipt of the information.

Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, if at all. The FDA or the sponsor or its data 
safety monitoring board may suspend or terminate a clinical trial at any time on various grounds, including a finding that the research patients are being 
exposed  to  an  unacceptable  health  risk,  including  risks  inferred  from  other  unrelated  immunotherapy  trials.  Similarly,  an  IRB  can  suspend  or  terminate 
approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the biological product 
has been associated with unexpected serious harm to patients.

Concurrently  with  clinical  trials,  companies  usually  complete  additional  studies  and  must  also  develop  additional  information  about  the  physical 
characteristics  of  the  biological  product  as  well  as  finalize  a  process  for  manufacturing  the  product  in  commercial  quantities  in  accordance  with  cGMP 
requirements. To help reduce the risk of the introduction of adventitious agents with use of biological products, the PHSA emphasizes the importance of 
manufacturing  control  for  products  whose  attributes  cannot  be  precisely  defined.  The  manufacturing  process  must  be  capable  of  consistently  producing 
quality batches of the product candidate and, among other things, the sponsor must develop methods for testing the identity, strength, quality, potency and 
purity  of  the  final  biological  product  according  to  the  requirements  of  the  phase  of  clinical  development.  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.

Further, as a result of the ongoing COVID-19 pandemic, the extent and length of which is uncertain, we will be required to develop and implement 
additional  clinical  study  policies  and  procedures  designed  to  help  protect  study  participants  from  the  COVID-19  virus,  which  may  include  using 
telemedicine visits and remote monitoring of patients and clinical sites. We will also need to ensure data from our clinical studies that may be disrupted as a 
result of the pandemic is collected pursuant to the study protocol and is consistent with GCPs, with any material protocol deviation reviewed and approved 
by the site IRB. Patients who may miss scheduled appointments, any interruption in study drug supply, or other consequence that may result in incomplete 
data being generated during a study as a result of the pandemic must be adequately documented and justified. For example, on March 18, 2020, the FDA 
issued a guidance on conducting clinical trials during the pandemic, which describes a number of considerations for sponsors of clinical trials impacted by 
the pandemic, including the requirement to include in the clinical study report (or as a separate document) contingency measures implemented to manage 
the study, and any disruption of the study as a result of COVID-19; a list of all study participants affected by COVID-19-related study disruption by unique 
subject  identifier  and  by  investigational  site,  and  a  description  of  how  the  individual’s  participation  was  altered;  and  analyses  and  corresponding 
discussions  that  address  the  impact  of  implemented  contingency  measures  (e.g.,  participant  discontinuation  from  investigational  product  and/or  study, 
alternative procedures used to collect critical safety and/or efficacy data) on the safety and efficacy results reported for the study. The FDA has continued to 
update and revise its guidance for ongoing clinical trials throughout the COVID-19 public health emergency.

United States 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  safety,  efficacy,  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  or  guarantee  that  the  FDA  will  accept  the  BLA  for  filing  and,  even  if  filed,  that  any 
approval will be granted on a timely basis, if at all.

Under the Prescription Drug User Fee Act (PDUFA), as amended, each BLA must be accompanied by a significant user fee. The FDA adjusts the 
PDUFA user fees on an annual basis. PDUFA also imposes an annual program fee for biological products. Fee waivers or reductions are available in certain 
circumstances, including a waiver of the application fee for the first application filed by a small business. Additionally, no user fees are assessed on BLAs 
for products designated as orphan drugs, unless the product also includes a non-orphan indication.

Within 60 or 74 days following submission of the application, the FDA reviews a BLA submitted to determine if it is substantially complete before 
the agency accepts it for filing. The FDA may refuse to file any BLA that it deems incomplete or not properly reviewable at the time of submission and 
may request additional information. In this event, the BLA must be resubmitted with the additional information. The resubmitted application also is subject 
to review before the FDA accepts it for filing. Under the goals and policies agreed to by the FDA under PDUFA, the FDA has 10 months from the filing 
date to complete its initial review of an original BLA and respond to the applicant, and six months from the filing date of an original BLA 

32

 
designated  for  priority  review.  The  FDA  does  not  always  meet  its  PDUFA  goal  dates  for  standard  and  priority  BLAs,  and  the  review  process  is  often 
extended by FDA requests for additional information or clarification.

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. Both Kymriah® 
and Yescarta® were approved with a REMS.

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  cellular  immunotherapy  products,  the  FDA  also  will  not  approve  the  product  if  the  manufacturer  is  not  in 
compliance with current good tissues practices (cGTP), to the extent applicable. These are FDA regulations and guidance documents that in part govern the 
methods used in, and the facilities and controls used for, the manufacture of human cells, tissue, and 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.

Pediatric Information

In addition, under the Pediatric Research Equity Act, 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. A sponsor who is planning to submit 
a  marketing  application  for  a  drug  that  includes  a  new  active  ingredient,  new  indication,  new  dosage  form,  new  dosing  regimen  or  new  route  of 
administration must submit an initial Pediatric Study Plan (PSP), within sixty (60) days of an end-of-Phase 2 meeting or, if there is no such meeting, as 
early as practicable before the initiation of the Phase 3 or Phase 2/3 study. The initial PSP must include an outline of the pediatric study or studies that the 
sponsor plans to conduct, including study objectives and design, age groups, relevant endpoints and statistical approach, or a justification for not including 
such  detailed  information,  and  any  request  for  a  deferral  of  pediatric  assessments  or  a  full  or  partial  waiver  of  the  requirement  to  provide  data  from 
pediatric studies along with supporting information. The FDA and the sponsor must reach an agreement on the PSP. A sponsor can submit amendments to 
an agreed-upon initial PSP at any 

33

 
time if changes to the pediatric plan need to be considered based on data collected from preclinical studies, early phase clinical trials and/or other clinical 
development programs.

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 U.S., 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

FDA provides programs intended to facilitate and expedite development and review of new products that are intended to address an unmet medical 
need  in  the  treatment  of  a  serious  or  life-threatening  disease  or  condition.  These  programs  are  referred  to  as  fast  track  designation,  priority  review 
designation, accelerated approval, Regenerative Medicine Advanced Therapy (RMAT) designation, and breakthrough therapy designation.

The fast track program 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.  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, for products being considered for accelerated approval,  the FDA generally requires, unless otherwise informed by the agency, that all 
advertising  and  promotional  materials  intended  for  dissemination  or  publication  within  120  days  of  marketing  approval  be  submitted  to  the  agency  for 
review during the pre-approval review period, which could adversely impact the timing of the commercial launch of the product.

Regenerative Medicine Advanced Therapy (RMAT), designation was established by the 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 

34

 
meetings  with  FDA  to  discuss  the  development  plan  for  the  product  candidate  and  eligibility  for  rolling  review  and  priority  review.  Products  granted 
RMAT designation may also be eligible for accelerated approval on the basis of a surrogate or intermediate endpoint reasonably likely to predict long-term 
clinical benefit, or reliance upon data obtained from a meaningful number of sites, including through expansion to additional sites. Once approved, when 
appropriate, the FDA can permit fulfillment of post-approval requirements under accelerated approval through the submission of clinical evidence, clinical 
studies, patient registries, or other sources of real world evidence such as electronic health records; through the collection of larger confirmatory datasets; 
or through post-approval monitoring of all patients treated with the therapy prior to approval.

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

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

development or regulatory approval process for our products.

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  physician  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.

Further,  additional  FDA  limitations  on  approval  or  marketing  could  restrict  the  commercial  promotion,  distribution,  prescription  or  dispensing  of 
products.  Product  approvals  may  be  withdrawn  for  non-compliance  with  regulatory  standards  or  if  problems  occur  following  initial  marketing.  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  may  also  require  the  implementation  of  other  risk  management  measures,  including  a  REMS,  or  the  conduct  of  post-marketing 
studies to assess a newly discovered safety issue.

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

We  rely,  and  expect  to  continue  to  rely,  on  third  parties  to  produce  clinical  and  commercial  quantities  of  our  products  in  accordance  with  cGMP 
regulations.  These  manufacturers  must  comply  with  cGMP  regulations  that  require,  among  other  things,  quality  control  and  quality  assurance,  the 
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 biologics 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 requirements and other laws.

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 

35

 
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  of  2009  (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. BPCIA, however, bars the FDA from approving biosimilar applications for 12 
years after an innovator biological product receives initial marketing approval. This 12-year period of data exclusivity may be extended by six months, for 
a total of 12.5 years, if the FDA requests that the innovator company conduct pediatric clinical investigations of the product.

Depending upon the timing, duration and specifics of the FDA approval of the use of our product candidates, some of our United States 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  United 
States 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 United States Department of Health and Human Services 
(HHS) (e.g., the Office of Inspector General, the United States Department of Justice (DOJ), and individual United States Attorney offices within the DOJ, 
and state and local governments). For example, our business practices, including any of our research and future sales, marketing and scientific/educational 
grant  programs  may  be  required  to  comply  with  the  anti-fraud  and  abuse  provisions  of  the  Social  Security  Act,  the  false  claims  laws,  the  patient  data 
privacy and security provisions of the Health Insurance Portability and Accountability Act of 1996 (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  the  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  (ACA),  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 ACA codified 
case law that 

36

 
a claim that includes items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of 
the federal civil False Claims Act (discussed below).

The civil monetary penalties statute imposes penalties against any person or entity who, among other things, is determined to have presented or caused 
to be presented a claim to, among others, a federal healthcare program that the person knows or should know is for a medical or other item or service that 
was not provided as claimed or is false or fraudulent.

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

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

Also, many states have similar fraud and abuse statutes or regulations, such as state anti-kickback and false claims laws, which may be broader in 
scope and apply regardless of payor. These laws are enforced by various state agencies and through private actions. Some state laws require pharmaceutical 
companies  to  comply  with  the  pharmaceutical  industry’s  voluntary  compliance  guidelines  and  the  relevant  federal  government  compliance  guidance, 
require drug manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers, and restrict 
marketing practices or require disclosure of marketing expenditures. In addition, certain state and local laws require the registration of pharmaceutical sales 
representatives.

We may be subject to data privacy and security regulations by both the federal government and the states in which we conduct business. HIPAA, as 
amended by the Health Information Technology for Economic and Clinical Health Act (HITECH) and their implementing regulations, impose 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.

We may also be subject to federal government price reporting laws, which require us to calculate and report complex pricing metrics in an accurate 
and  timely  manner  to  government  programs,  as  well  as  federal  consumer  protection  and  unfair  competition  laws,  which  broadly  regulate  marketplace 
activities that potentially harm consumers.

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,  as  defined  by  such  law,  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. Effective January 1, 2022, these 
reporting obligations extend to include transfers of value made to certain non-physician providers (physician assistants, nurse practitioners, clinical nurse 
specialists, certified registered nurse anesthetists and anesthesiologist assistants, and certified nurse midwives). 

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 

37

 
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,  refusal  to  allow  us  to  enter  into  government 
contracts, contractual damages, reputational harm, administrative burdens, diminished profits and future earnings, additional reporting requirements and/or 
oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, and the 
curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations.

Coverage, Pricing and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any product candidates for which we obtain regulatory approval. In the 
United States and markets in other countries, sales of any products for which we receive regulatory approval for commercial sale will depend, in part, on 
the  extent  to  which  third-party  payors  provide  coverage,  and  establish  adequate  reimbursement  levels  for  such  products.  In  the  U.S.,  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  European  Union  (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 U.S., the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by 
major legislative initiatives.

38

 
For  example,  the  ACA  has  substantially  changed  healthcare  financing  and  delivery  by  both  governmental  and  private  insurers.  Among  the  ACA 

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  50%  (increase  to  70% 
pursuant to the Bipartisan Budget Act of 2018, effective as of January 1, 2019) point-of-sale discounts, off negotiated prices of applicable 
brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturers’ outpatient drugs to be covered 
under Medicare Part D;

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

expanded  eligibility  criteria  for  Medicaid  programs  by,  among  other  things,  allowing  states  to  offer  Medicaid  coverage  to  additional 
individuals  and  added  new  mandatory  eligibility  categories  for  individuals  with  income  at  or  below  133%  of  the  federal  poverty  level, 
thereby potentially increasing manufacturers’ Medicaid rebate liability;

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

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

expanded healthcare fraud and abuse laws, including the Anti-Kickback Statute and the Foreign Corrupt Practices Act (FCPA), created new 
government investigative powers, and enhanced penalties for noncompliance;

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

required reporting of certain financial arrangements with physicians and teaching hospitals;

required annual reporting of certain information regarding drug samples that manufacturers and distributors provide to physicians;

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.

There remain legal and political challenges to certain aspects of the ACA. On June 17, 2021, the Supreme Court dismissed the most recent judicial 
challenge  to  the  ACA  brought  by  several  states  without  specifically  ruling  on  the  constitutionality  of  the  ACA.  Prior  to  the  Supreme  Court's  decision, 
President Biden issued an executive order to initiate a special enrollment period from February 15, 2021 through August 15, 2021 for purposes of obtaining 
health insurance coverage through the ACA marketplace. The executive order also instructed certain governmental agencies to review and reconsider their 
existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that 
include work requirements, and policies that create barriers to unnecessary barriers to obtaining access to health insurance coverage through Medicaid or 
the ACA. It is unclear how other healthcare reform measures of the Biden administration or other efforts, if any, to challenge, repeal or replace the ACA 
will impact our business. In addition, other legislative and regulatory changes have been proposed and adopted in the United States since the ACA was 
enacted. 

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 ACA was enacted: 

•

On August 2, 2011, President Obama signed into law the Budget Control Act of 2011, which, among other things, created the Joint Select 
Committee  on  Deficit  Reduction  to  recommend  to  Congress  proposals  in  spending  reductions.  The  Joint  Select  Committee  on  Deficit 
Reduction did not achieve a targeted deficit reduction of at least $1.2 trillion for fiscal years 2012 through 2021, triggering the legislation’s 
automatic reduction to several government programs. This includes aggregate reductions to Medicare payments to providers of up to 2% per 
fiscal year, which went into effect beginning on April 1, 2013 and will stay in effect through 2030 unless additional 

39

 
Congressional action is taken. Pursuant to the Coronavirus Aid, Relief, and Economic Security Act, also known as the CARES Act, as well 
as subsequent legislation, these reductions have been suspended from May 1, 2020 through March 31, 2022 due to the COVID-19 pandemic. 
Following  the  temporary  suspension,  a  1%  payment  reduction  will  occur  beginning  April  1,  2022  through  June  30,  2022,  and  the  2% 
payment reduction will resume on July 1, 2022.

On January 2, 2013, the U.S. American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced 
Medicare payments to several types of providers.

On April 13, 2017, CMS published a final rule that gives states greater flexibility in setting benchmarks for insurers in the individual and 
small group marketplaces, which may have the effect of relaxing the essential health benefits required under the ACA for plans sold through 
such marketplaces.

On May 30, 2018, the Right to Try Act, was signed into law. The law, among other things, provides a federal framework for certain patients 
to access certain investigational new drug products that have completed a Phase 1 clinical trial and that are undergoing investigation for FDA 
approval. Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without obtaining FDA 
permission under the FDA expanded access program. There is no obligation for a pharmaceutical manufacturer to make its drug products 
available to eligible patients as a result of the Right to Try Act. 

On May 23, 2019, CMS published a final rule to allow Medicare Advantage Plans the option of using step therapy for Part B drugs beginning 
January 1, 2020.

On December 20, 2019, former President Trump signed into law the Further Consolidated Appropriations Act (H.R. 1865), which repealed 
the Cadillac tax, the health insurance provider tax, and the medical device excise tax.  It is impossible to determine whether similar taxes 
could be instated in the future.

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 United States  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, President Biden signed an Executive Order on July 9, 2021 affirming the administration’s policy to (i) support legislative reforms 
that would lower the prices of prescription drug and biologics, including by allowing Medicare to negotiate drug prices, by imposing inflation caps, and, by 
supporting  the  development  and  market  entry  of  lower-cost  generic  drugs  and  biosimilars;  and  (ii)  support  the  enactment  of  a  public  health  insurance 
option. Among other things, the Executive Order also directs HHS to provide a report on actions to combat excessive pricing of prescription drugs, enhance 
the domestic drug supply chain, reduce the price that the Federal government pays for drugs, and address price gouging in the industry; and directs the 
FDA to work with states and Indian Tribes that propose to develop section 804 Importation Programs in accordance with the Medicare Prescription Drug, 
Improvement, and Modernization Act of 2003, and the FDA’s implementing regulations. FDA released such implementing regulations on September 24, 
2020,  which  went  into  effect  on  November  30,  2020,  providing  guidance  for  states  to  build  and  submit  importation  plans  for  drugs  from  Canada.  On 
September 25, 2020, CMS stated drugs imported by states under this rule will not be eligible for federal rebates under Section 1927 of the Social Security 
Act and manufacturers would not report these drugs for “best price” or Average Manufacturer Price purposes. Since these drugs are not considered covered 
outpatient drugs, CMS further stated it will not publish a National Average Drug Acquisition Cost for these drugs. If implemented, importation of drugs 
from Canada may materially and adversely affect the price we receive for any of our product candidates. Further, on November 20, 2020 CMS issued an 
Interim  Final  Rule  implementing  the  Most  Favored  Nation,  or  MFN,  Model  under  which  Medicare  Part  B  reimbursement  rates  would  have  been  be 
calculated  for  certain  drugs  and  biologicals  based  on  the  lowest  price  drug  manufacturers  receive  in  Organization  for  Economic  Cooperation  and 
Development countries with a similar gross domestic product per capita.  However, on December 29, 2021 CMS rescinded the Most Favored Nations rule. 
Additionally, on November 30, 2020, HHS published a regulation removing safe harbor protection for price reductions from pharmaceutical manufacturers 
to plan sponsors under Part D, either directly or through pharmacy benefit managers, unless the price reduction is required by law. The rule also creates a 
new safe harbor for price reductions reflected at the point-of-sale, as well as a safe harbor for certain fixed fee arrangements between pharmacy benefit 
managers  and  manufacturers.  Pursuant  to  court  order,  the  removal  and  addition  of  the  aforementioned  safe  harbors  were  delayed  and  recent  legislation 
imposed  a  moratorium  on  implementation  of  the  rule  until  January  1,  2026.  Although  a  number  of  these  and  other  proposed  measures  may  require 
authorization through additional legislation to become effective, and the Biden administration may reverse or otherwise change these measures, both the 
Biden administration and Congress have indicated that they will continue to seek new legislative measures to control drug costs. 

Individual  states  in  the  United  States  have  also  increasingly  passed  legislation  and  implemented  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. Individual states in the United 
States  have also been increasingly passing legislation 

40

 
and  implementing  regulations  designed  to  control  pharmaceutical  and  biological  product  pricing,  including  price  or  patient  reimbursement  constraints, 
discounts,  restrictions  on  certain  product  access  and  marketing  cost  disclosure  and  transparency  measures,  and,  in  some  cases,  designed  to  encourage 
importation from other countries and bulk purchasing.

We anticipate that these and other healthcare reform efforts will continue to result in additional downward pressure on coverage and the price that we 
receive for any approved product, and could materially 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.

The Foreign Corrupt Practices Act

The FCPA prohibits any United States individual or business from offering, paying, promising to pay, or authorizing payment of money or anything of 
value, to any person, while knowing that all or a portion of such money or thing of value will be offered, given or promised, directly or indirectly, to any 
foreign official, political party or candidate to influence the foreign official in his or her official capacity, induce the foreign official to do or omit to do an 
act in violation of his or her lawful duty, or to secure any improper advantage 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  certain  accounting  provisions  requiring  us  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.  Compliance  with  the  FCPA  is  expensive  and  difficult,  particularly  in  countries  in  which 
corruption  is  a  recognized  problem.  In  addition,  the  FCPA  presents  particular  challenges  in  the  pharmaceutical  industry,  because,  in  many  countries, 
hospitals  are  owned  and  operated  by  the  government,  and  doctors  and  other  hospital  employees  are  considered  foreign  officials  for  the  purposes  of  the 
statute. Certain payments made in connection with clinical trials and other work have been deemed to be improper payments to government officials and 
have led to FCPA enforcement actions. Various laws, regulations and executive orders also restrict the use and dissemination outside of the U.S., or the 
sharing with certain non-United States  nationals, of information classified for national security purposes, as well as certain products and technical data 
relating to those products.

Accordingly, if we expand our presence outside of the U.S., we will need to dedicate additional resources to complying with the laws and regulations 
in each jurisdiction in which it plans to operate. Therefore, this may preclude us from developing, manufacturing, or selling certain products and product 
candidates outside of the U.S., which could limit our growth potential and increase our development costs.

Packaging and Distribution in the United States

If our products are made available to authorized users of the Federal Supply Schedule of the General Services Administration, additional laws and 
requirements  apply.  Products  must  meet  applicable  child-resistant  packaging  requirements  under  the  United  States    Poison  Prevention  Packaging  Act. 
Manufacturing, sales, promotion and other activities also are potentially subject to federal and state consumer protection and unfair competition laws.

The  distribution  of  pharmaceutical  products  is  subject  to  additional  requirements  and  regulations,  including  extensive  record-keeping,  licensing, 
storage and security requirements intended to prevent the unauthorized sale of pharmaceutical products. The failure to comply with any of these laws or 
regulatory  requirements  subjects  firms  to  possible  legal  or  regulatory  action.  Depending  on  the  circumstances,  failure  to  meet  applicable  regulatory 
requirements can result in criminal prosecution, fines or other penalties, injunctions, exclusion from federal healthcare programs, requests for recall, seizure 
of products, total or partial suspension of production, denial or withdrawal of product approvals, or refusal to allow a firm to enter into supply contracts, 
including  government  contracts.  Any  action  against  us  for  violation  of  these  laws,  even  if  we  successfully  defend  against  it,  could  cause  us  to  incur 
significant legal expenses and divert our management’s attention from the operation of our business. Prohibitions or restrictions on sales or withdrawal of 
future products marketed by us could materially affect our business in an adverse way.

Changes  in  regulations,  statutes  or  the  interpretation  of  existing  regulations  could  impact  our  business  in  the  future  by  requiring,  for  example:  (i) 
changes to our manufacturing arrangements; (ii) additions or modifications to product labeling; (iii) the recall or discontinuation of our products; or (iv) 
additional record-keeping requirements. If any such changes were to be imposed, they could adversely affect the operation of our business.

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, 

41

 
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.

Even if we contract with third parties for the disposal of these materials and waste products, we cannot completely eliminate the risk of contamination 
or injury resulting from these materials. If our operations result in contamination of the environment or expose individuals to hazardous substances, we 
could be liable for damages and governmental fines, and any liability could exceed our resources. We also could incur significant costs associated with civil 
or  criminal  fines  and  penalties  for  failure  to  comply  with  such  laws  and  regulations.  We  maintain  workers’  compensation  insurance  to  cover  costs  and 
expenses it may incur due to injuries to our employees, but this insurance may not provide adequate coverage against potential liabilities. However, we do 
not maintain insurance for environmental liability or toxic tort claims that may be asserted against it. In addition, we may incur substantial costs in order to 
comply with current or future environmental, health and safety laws and regulations. Current or future environmental laws and regulations may impair our 
research, development or production efforts. In addition, failure to comply with these laws and regulations may result in substantial fines, penalties or other 
sanctions.

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 U.S., 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.

In  April  2014,  the  EU  adopted  the  new  Clinical  Trials  Regulation  (EU)  No  536/2014,  or  Regulation,  which  replaced  the  Clinical  Trials  Directive 
2001/20/EC, or Directive, on January 31, 2022. The new Regulation overhauls the current system of approvals for clinical trials in the EU. Specifically, the 
new  Regulation,  which  is  directly  applicable  in  all  EU  member  states  (meaning  that  no  national  implementing  legislation  in  each  EU  member  state  is 
required), aims at simplifying and streamlining the approval of clinical trials in the EU. The main characteristics of the regulation include: a streamlined 
application  procedure  via  a  single-entry  point  through  the  Clinical  Trials  Information  System,  or  CTIS;  a  single  set  of  documents  to  be  prepared  and 
submitted  for  the  application  as  well  as  simplified  reporting  procedures  for  clinical  trial  sponsors;  and  a  harmonized  procedure  for  the  assessment  of 
applications for clinical trials.

To obtain regulatory approval of a medicinal product under EU regulatory systems, we must submit an MAA. The centralized procedure provides for 
the grant of a single marketing authorization by the European Commission that is valid across all of the EU, and in the additional member states of the 
European Economic Area (Iceland, Liechtenstein and Norway). The scientific evaluation of MAAs for Advanced Therapy Medicinal Product, or ATMPS 
(which comprise gene therapy, somatic cell therapy and tissue engineered medicines) is primarily performed by a specialized scientific committee called 
the Committee for Advanced Therapies, or CAT. The CAT prepares a draft opinion on the quality, safety and efficacy of the ATMP which is the subject of 
the MAA, which is sent for final approval to the Committee for Medicinal Products for Human Use, or CHMP. The CHMP recommendation is then sent to 
the  European  Commission,  which  adopts  a  decision  binding  in  all  EU  Member  States.  The  maximum  timeframe  for  the  evaluation  of  an  MAA  for  an 
ATMP is 210 days from receipt of a valid MAA, excluding clock stops when additional information or written or oral explanation is to be provided by the 
applicant in response to questions asked by the CAT and/or CHMP. Clock stops may extend the timeframe of evaluation of an MAA considerably beyond 
210 days. Where the CHMP gives a positive opinion, the EMA provides the opinion together with supporting documentation to the European Commission, 
who  make  the  final  decision  to  grant  a  marketing  authorization,  which  is  issued  within  67  days  of  receipt  of  the  EMA’s  recommendation.  Accelerated 
assessment may be granted by the CHMP in exceptional cases, when a medicinal product is of major public health interest, particularly from the viewpoint 
of therapeutic innovation. If the CHMP accepts such a request, the timeframe of 210 days for assessment will be reduced to 150 days (excluding clock 
stops), but it is possible that the CHMP may revert to the standard time limit for the centralized procedure if it determines that the application is no longer 
appropriate to conduct an accelerated assessment.

Products with an orphan designation in the EU can receive ten years of market exclusivity, during which time “no similar medicinal product” for the 

same indication may be placed on the market. A “similar medicinal product” is defined as a medicinal 

42

 
product containing a similar active substance or substances as contained in an authorized orphan medicinal product, and which is intended for the same 
therapeutic indication. An orphan product can also obtain an additional two years of market exclusivity in the EU where an agreed pediatric investigation 
plan for pediatric studies has been complied with. The criteria for designating an “orphan medicinal product” in the EU are similar in principle to those in 
the United States. Under Article 3 of Regulation (EC) 141/2000, a medicinal product may be designated as an orphan medicinal product if it meets the 
following criteria: (1) it is intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition; and (2) either (i) the 
prevalence of such condition must not be more than five in 10,000 persons in the EU when the application is made, or (ii) without the benefits derived from 
orphan status, it must be unlikely that the marketing of the medicine would generate sufficient return in the EU to justify the investment needed for its 
development; and (3) there exists no satisfactory method of diagnosis, prevention or treatment of such condition authorized for marketing in the EU, or if 
such  a  method  exists,  the  product  will  be  of  significant  benefit  to  those  affected  by  the  condition,  as  defined  in  Regulation  (EC)  847/2000.  Orphan 
medicinal products are eligible for financial incentives such as reduction of fees or fee waivers and are, upon grant of a marketing authorization, entitled to 
ten years of market exclusivity for the approved therapeutic indication. The application for orphan designation must be submitted before the application for 
marketing authorization. The applicant will receive a fee reduction for the MAA if the orphan designation has been granted, but not if the designation is 
still pending at the time the marketing authorization is submitted. Orphan designation does not convey any advantage in, or shorten the duration of, the 
regulatory review and approval process. The 10-year market exclusivity may be reduced to six years if, at the end of the fifth year, it is established that the 
product  no  longer  meets  the  criteria  for  orphan  designation,  for  example,  if  the  product  is  sufficiently  profitable  not  to  justify  maintenance  of  market 
exclusivity. Otherwise, orphan medicine marketing exclusivity may be revoked only in very select cases, such as if: (i) a second applicant can establish that 
its  product,  although  similar,  is  safer,  more  effective  or  otherwise  clinically  superior;  (ii)  the  marketing  authorization  holder  of  the  authorized  orphan 
product  consents  to  a  second  orphan  medicinal  product  application;  or  (iii)  the  marketing  authorization  holder  of  the  authorized  orphan  product  cannot 
supply enough orphan medicinal product.  

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

If we 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  contracts  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.

In addition, further to the U.K.’s exit from the EU on January 31, 2020, the GDPR ceased to apply in the U.K. at the end of the transition period on 
December 31, 2020. However, as of January 1, 2021, the U.K.’s European Union (Withdrawal) Act 2018 incorporated the U.K. GDPR into U.K. law. The 
U.K.  GDPR  and  the  U.K.  Data  Protection  Act  2018  set  out  the  U.K.’s  data  protection  regime,  which  is  independent  from  but  aligned  to  the  EU’s  data 
protection regime. Non-compliance with the U.K. GDPR may result in monetary penalties of up to £17.5 million or 4% of worldwide revenue, whichever 
is higher. Although the UK is regarded as a third country under the EU’s GDPR, the European Commission (“EC”) has now issued a decision recognizing 
the UK as providing adequate protection under the EU GDPR and, therefore, transfers of personal data originating in the EU to the UK remain unrestricted. 
Like the EU GDPR, the UK GDPR restricts personal data transfers outside the UK to countries not regarded by the UK as providing adequate protection. 
The UK government has confirmed that personal data transfers from the UK to the EEA remain free flowing. 

43

 
To enable the transfer of personal data outside of the EEA or the UK, adequate safeguards must be implemented in compliance with European and UK 
data protection laws. On June 4, 2021, the EC issued new forms of standard contractual clauses for data transfers from controllers or processors in the 
EU/EEA (or otherwise subject to the GDPR) to controllers or processors established outside the EU/EEA (and not subject to the GDPR). The new standard 
contractual clauses replace the standard contractual clauses that were adopted previously under the EU Data Protection Directive. The UK is not subject to 
the  EC’s  new  standard  contractual  clauses  but  has  published  a  draft  version  of  a  UK-specific  transfer  mechanism,  which,  once  finalized,  will  enable 
transfers from the UK. We will be required to implement these new safeguards when conducting restricted data transfers under the EU and UK GDPR and 
doing so will require significant effort and cost.

Compliance with these and any other applicable privacy and data security laws and regulations is a rigorous and time-intensive process, and we may 
be  required  to  put  in  place  additional  mechanisms  ensuring  compliance  with  the  new  data  protection  rules.  If  we  fail  to  comply  with  any  such  laws  or 
regulations, we may face significant fines and penalties that could adversely affect our business, financial condition and results of operations. 

U.S. Data Privacy Law

California recently enacted legislation, effective January 1, 2020, that has been dubbed the first “GDPR-like” law in the United States. Known as the 
California Consumer Privacy Act (CCPA), it creates new individual privacy rights for consumers (as that word is broadly defined in the law) and places 
increased  privacy  and  security  obligations  on  entities  handling  personal  data  of  consumers  or  households.  The  CCPA  requires  covered  companies  to 
provide new disclosures to California consumers, provides such consumers new ways to opt-out of certain sales of personal information, and allows for a 
new cause of action for data breaches. As our business progresses, the CCPA may 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.

Some observers have noted that the CCPA could mark the beginning of a trend toward more stringent privacy legislation in the United States, which 

could increase our potential liability and adversely affect our business. 

Further, a new California privacy law, the California Privacy Rights Act, or CPRA, was passed by California voters on November 3, 2020. The CPRA 
will create additional obligations with respect to processing and storing personal information that are scheduled to take effect on January 1, 2023 (with 
certain  provisions  having  retroactive  effect  to  January  1,  2022).  Additionally,    some  observers  have  noted  that  the  CCPA  and  CPRA  could  mark  the 
beginning of a trend toward more stringent privacy legislation in the U.S., which could increase our potential liability and adversely affect our business. 
Already,  in  the  United  States,  we  have  witnessed  significant  developments  at  the  state  level.  For  example,  on  March  2,  2021,  Virginia  enacted  the 
Consumer Data Protection Act (the “CDPA”) and, on July 8, 2021, Colorado’s governor signed the Colorado Privacy Act (“CPA”), into law. The CDPA 
and the CPA will both become effective January 1, 2023. While the CDPA and CPA incorporate many similar concepts of the CCPA and CPRA, there are 
also several key differences in the scope, application, and enforcement of the law that will change the operational practices of regulated businesses. The 
new  laws  will,  among  other  things,  impact  how  regulated  businesses  collect  and  process  personal  sensitive  data,  conduct  data  protection  assessments, 
transfer personal data to affiliates, and respond to consumer rights requests.

A number of other states have proposed new privacy laws, some of which are similar to the above discussed recently passed laws. Such proposed 
legislation,  if  enacted,  may  add  additional  complexity,  variation  in  requirements,  restrictions  and  potential  legal  risk,  require  additional  investment  of 
resources in compliance programs, impact strategies and the availability of previously useful data and could result in increased compliance costs and/or 
changes  in  business  practices  and  policies.  The  existence  of  comprehensive  privacy  laws  in  different  states  in  the  country  would  make  our  compliance 
obligations  more  complex  and  costly  and  may  increase  the  likelihood  that  we  may  be  subject  to  enforcement  actions  or  otherwise  incur  liability  for 
noncompliance.

Human Capital

As of December 31, 2021, we had 86 full-time employees and 16 consultants. Of our full-time employees, 24 hold a Ph.D. and 4 hold a M.D. None of 
our  employees  are  represented  by  labor  unions  or  covered  by  collective  bargaining  agreements.  We  consider  our  relationship  with  our  employees  to  be 
good. 

We offer attractive benefits, including competitive salaries, excellent health insurance, and a 401K match. We are committed to pay equity, regardless 
of  gender,  race/ethnicity,  or  sexual  orientation  and  conduct  comprehensive  pay  equity  analyses  on  a  semi-annual  basis.  In  addition  to  providing  strong 
benefits  packages  to  employees,  we  believe  in  fostering  individual  and  organizational  effectiveness  by  offering  our  employees  various  professional 
development opportunities. We believe that investing in our employees’ career growth provides individuals and the organization with the knowledge and 
skills to respond effectively to current and future business demands and support to the organization’s development efforts. Our culture is one that actively 
supports the application of new knowledge and skills on the job. In 2022, we plan to continue add to our human capital resources as we grow. We are also 
monitoring the current landscape of wage inflation and labor shortages in connection with our employees' overall compensation.

Corporate Information

Prior  to  September  15,  2020,  we  were  a  clinical-stage  biopharmaceutical  company  known  as  resTORbio,  Inc.  that  had  historically  focused  on 
developing  innovative  medicines  that  target  the  biology  of  aging,  to  prevent  or  treat  age-related  diseases  with  the  potential  to  extend  healthy  lifespan. 
resTORbio  was  originally  incorporated  under  the  laws  of  the  State  of  Delaware  in  July  2016  and  commenced  research  and  development  operations  in 
March 2017.

On September 15, 2020, we completed our business combination whereby a wholly owned subsidiary of resTORbio, Inc. merged with and into Adicet 
Bio, Inc., with Adicet Bio, Inc. surviving as a wholly-owned subsidiary of resTORbio and changing our name to Adicet Therapeutics, Inc. In connection 
with the completion of the Merger, resTORbio was renamed Adicet Bio, Inc. (Adicet Bio).

Immediately prior to the Effective Time of the Merger, resTORbio effected a reverse stock split of our common stock at a ratio of 1-for-7. At the 
Effective  Time  of  the  Merger,  each  outstanding  share  of  former  our  capital  stock  was  converted  into  the  right  to  receive  0.1240  shares  of  resTORbio 
common stock.

Item 1A. Risk Factors. 

Investing  in  our  common  stock  involves  a  high  degree  of  risk.  In  evaluating  the  Company  and  our  business,  you  should  carefully  consider  the 
following risks and uncertainties, together with all other information in this Annual Report on Form 10-K, including our consolidated financial statements 
and related notes and “Management’s Discussion and Analysis of Results of Operations and Financial Condition,” as well as our other filings with the 
Securities and Exchange Commission (SEC), before investing in our common stock. Any of the risk factors we describe below could adversely affect our 
business, financial condition or results of operations. The market price of our common stock could decline if one or more of these risks or uncertainties 
actually occur, causing you to lose all or part of your investment in our common stock. The risks and uncertainties we describe below are not the only ones 
we face. Additional risks and uncertainties that we currently do not know about or that we currently believe to be immaterial may also impair our business. 
Certain statements below are forward-looking statements. See “Special Note Regarding Forward-Looking Statements and Industry Data” in this Annual 
Report on Form 10-K.

Risks Related to Our Business and Industry

Risks Related to Operating History

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

Biopharmaceutical  product  development  is  a  highly  speculative  undertaking  and  involves  a  substantial  degree  of  risk.  We  began  operation  in 
November 2014. We have a limited operating history upon which someone can evaluate our business and prospects and is subject to the risks inherent in 
any early stage company, including, among other things, risks that we may not be able to hire sufficient qualified personnel and establish operating controls 
and procedures. We currently do not have complete in-house resources to enable our gamma delta T cell platform. 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. Consequently, any predictions made about our future success or viability may not be as accurate as they could be if we had a 
history of successfully developing and commercializing biopharmaceutical products.

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  an  early  clinical  stage  biopharmaceutical  company.  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  effect  or  an 
acceptable  safety  profile,  gain  regulatory  approval  and  become  commercially  viable.  We  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.  To  date,  we  have  financed  our 
operations  primarily  with  proceeds  from  our  license  and  collaboration  agreements  and  the  issuance  and  sale  of  our  capital  stock,  including  a  follow-on 
public  offering  in  December  2021  which  raised  net  proceeds  of  approximately  $94.2  million  from  the  sale  of  our  common  stock.  For  the  years  ended 
December 31, 2021 and 2020, we reported net losses of $62.0 million and $36.7 million, respectively. As of December 31, 2021, we had an accumulated 
deficit of $168.3 million.

We expect to incur significant expenditures for the foreseeable future, and we expect these expenditures to increase as we continue our research and 
development of, and seek regulatory approvals for, product candidates based on our gamma delta T cell platform, including ADI-001. 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. Further, even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to 
become and remain profitable would depress the value of our company and could impair our ability to raise capital, expand our business, maintain our 
research and development efforts, diversify our product candidates or even continue our operations, any of which could have a material adverse effect on 
our business, financial condition, results of operations, and prospects and cause investors to lose all or part of their investments.

46

 
Our history of recurring losses and anticipated expenditures could raise substantial doubts about our ability to continue as a going concern. 

In  our  financial  statements  for  the  period  ending  to  December  31,  2020,  we  concluded  that  our  recurring  losses  from  operations  and  need  for 
additional  financing  to  fund  future  operations  raised  substantial  doubt  about  our  ability  to  continue  as  a  going  concern.  Similarly,  our  independent 
registered public accounting firm included an explanatory paragraph in its report on our financial statements for the period ended December 31, 2020 with 
respect to this uncertainty. As of December 31, 2021, we believe that with our existing cash and cash equivalents we are able to fund our expenses and 
capital expenditure requirements beyond twelve months from the issuance of these financial statements and into the second half of 2024. Our ability to 
continue  as  a  going  concern  beyond  this  point  will  require  us  to  obtain  additional  funding.  If  we  are  unable  to  obtain  sufficient  funding,  our  business, 
prospects, financial condition and results of operations will be materially and adversely affected, and we may be unable to continue as a going concern. If 
we are unable to raise capital when needed or on acceptable terms, we would be forced to delay, limit, reduce or terminate our product development or 
future  commercialization  efforts  of  one  or  more  of  our  product  candidates,  or  may  be  forced  to  reduce  or  terminate  our  operations.  If  we  are  unable  to 
continue  as  a  going  concern,  we  may  have  to  liquidate  our  assets  and  may  receive  less  than  the  value  at  which  those  assets  are  carried  on  our  audited 
financial statements, and it is likely that investors will lose all or a part of their investment. In our own future required quarterly assessments, we may again 
conclude  that  there  is  substantial  doubt  about  our  ability  to  continue  as  a  going  concern,  and  future  reports  from  our  independent  registered  public 
accounting firm may also contain statements expressing substantial doubt about our ability to continue as a going concern. If we seek additional financing 
to fund our business activities in the future and there exists substantial doubt about our ability to continue as a going concern, investors or other financing 
sources may be unwilling to provide additional funding to us on commercially reasonable terms, if at all.

Risks Related to Our Product Candidates

Our business is highly dependent on the success of ADI-001. If we are unable to obtain approval for ADI-001 and effectively commercialize ADI-001  
for the treatment of patients in our 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 candidate, ADI-001. ADI-001 is in the early stages of development with an ongoing Phase 1 study to assess the safety and efficacy of ADI-001 in 
Non-Hodgkin's Lymphoma (NHL) patients that commenced in March 2021. 

Our  preclinical  or  clinical  results  to  date  may  not  predict  results  for  our  planned  or  ongoing  trials  or  any  future  studies  of  ADI-001  or  any  other 
allogeneic gamma delta T cell product candidate. Because of the lack of evaluation of allogeneic products and gamma delta T cell therapy products in the 
clinic to date, any such product’s failure, or the failure of other allogeneic T cell therapies or gamma delta T cell therapies, may significantly influence 
physicians’ and regulators’ opinions in regards to the viability of our entire pipeline of allogeneic T cell therapies, which could have a material adverse 
effect on our reputation. If our gamma delta T cell therapy is viewed as less safe or effective than autologous therapies or other allogeneic T cell therapies, 
our ability to develop other allogeneic gamma delta T cell therapies may be significantly harmed.

All of our product candidates, including ADI-001 , 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 ADI-001 is our most advanced product candidate, and because our other product candidates 
are based on similar technology, if ADI-001 encounters safety or efficacy problems, manufacturing problems, developmental delays, regulatory issues or 
other problems, our development plans and business would be significantly harmed, which could have a material adverse effect on our business, reputation 
and prospects.

Our gamma delta T cell candidates represent a novel approach to cancer treatment that creates significant challenges for us.

We are developing a pipeline of gamma delta T cell product candidates and a novel antibody platform that are intended for use in 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  future  clinical  trials,  and,  if  approved, 
commercialization;

sourcing future 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;

inability to achieve efficacy in cancer patients following treatment with our product candidates;

47

 
•

•

•

•

•

•

achieving a side effect profile, including graft-versus-host disease (GvHD), from our product candidates that makes them commercially attractive 
for further development;

educating medical personnel regarding the potential side effect profile of our product candidates, if approved;

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  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 success of our business, including our ability to obtain financing and generate any revenue in the future, will primarily depend on the successful 
development,  manufacturing,  positive  efficacy  and  safety  profile  in  our  clinical  trials,  regulatory  approval  and  commercialization  of  our  novel  product 
candidates, which may never occur. We have not yet succeeded and may not succeed in demonstrating efficacy and safety for any of our product candidates 
in  clinical  trials  or  in  obtaining  marketing  approval  thereafter.  Given  our  early  stage  of  development,  it  may  be  several  years,  if  at  all,  before  we  have 
demonstrated the safety and efficacy of a product candidate sufficient to warrant approval for commercialization. If we are unable to develop, or obtain 
regulatory approval for, or, if approved, successfully commercialize our product candidates, we may not be able to generate sufficient revenue to continue 
our business, which could have a material adverse effect on our results of operations and prospects.

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

We  have  concentrated  our  research  and  development  efforts  on  our  allogeneic  gamma  delta  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 product candidates and there can be no 
assurance that any development problems we have experienced or may experience in the future will not cause significant delays or result in unforeseen 
issues  or  unanticipated  costs,  or  that  any  such  development  problems  or  issues  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  future  clinical  studies  or  commercializing  our  products  on  a  timely  or  profitable  basis,  if  at  all.  In  addition,  our  expectations  with  regard  to  the 
advantages of an allogenic gamma delta T cell therapy platform relative to other therapies may not materialize or materialize to the degree we anticipate. 
Further, our scalability and costs of manufacturing may vary significantly as we develop our product candidates and understand these critical factors.

In  addition,  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.

Our product candidates may also 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 or alpha beta T cell therapies that may be approved in the future. Unexpected clinical 
outcomes could materially and adversely affect our business, results of operations and prospects.

48

 
Our product candidates may cause undesirable side effects or have other properties that could halt our clinical development, prevent our regulatory 
approval, limit our 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  cytokine  release  syndrome  and  neurotoxicity,  and 
adverse events have resulted in the death of patients. While we believe our gamma delta T cell approach may lessen such results, similar or other adverse 
events for our allogeneic gamma delta T cell product candidates may occur. In addition, while we anticipate our focus on gamma delta T cells may lessen 
the likelihood of GvHD relative to therapies relying on unrelated alpha beta T cells, similar or other adverse events for our allogeneic gamma delta T cell 
product candidates may occur.

If  unacceptable  toxicities  arise  in  the  development  of  our  product  candidates,  we  could  suspend  or  terminate  our  trials  or  the  FDA  or  comparable 
foreign regulatory authorities could order us to cease clinical trials or deny approval of our product candidates for any or all targeted indications. The data 
safety monitoring board may also suspend or terminate a clinical trial at any time on various grounds, including a finding that the research patients are 
being exposed to an unacceptable health risk, including risks inferred from other unrelated immunotherapy trials. Treatment-related side effects could also 
affect patient recruitment or the ability of enrolled subjects to complete the trial or result in potential product liability claims. Novel therapeutic candidates, 
such as those we are developing, may result in novel side effect profiles that may not be appropriately recognized or managed by the treating medical staff. 
We anticipate having to train medical personnel using our product candidates to understand the side effect profile of our product candidates for 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  serious  adverse  events  including  patient  deaths.  Based  on  available  preclinical  data  and  on  management’s  clinical 
experience  with  other  cell  therapy  agents,  the  safety  profile  of  our  pipeline  product  candidates  is  expected  to  include  cytokine  release  syndrome, 
neurotoxicity, and possibly additional adverse events. Any of these occurrences may have a material adverse effect our business, financial condition and 
prospects.

Risks Related to Clinical Trials

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  ADI-001  and  ADI-002,  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.

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 ADI-001 and ADI-002 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. Any of the foregoing could have a material adverse effect on our business, prospects and financial 
condition.

We may not be able to file investigational new drug (IND) applications 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.

In  October  2020,  the  IND  for  our  lead  product  candidate,  ADI-001,  to  treat  patients  with  NHL  was  cleared  by  the  FDA.  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. Moreover, we cannot be sure that submission of an IND for any of our other product 
candidates  will  result  in  the  FDA  allowing  trials  to  begin,  or  that,  once  begun,  issues  will  not  arise  that  result  in  a  decision  by  us,  by  independent 
Institutional Review Boards (IRBs) or independent ethics committees, or by the FDA or other regulatory authorities to suspend or terminate clinical trials. 
For 

49

 
example,  we  may  experience  manufacturing  delays  or  other  delays  with  IND-enabling  studies  or  the  FDA  or  other  regulatory  authorities  may  require 
additional preclinical studies that we did not anticipate.  Moreover, we cannot be assured that submission of an IND will result in the FDA allowing clinical 
trials to begin, or that, once begun, issues will not arise that result in a decision by us, by IRBs, or independent ethics committees or by the FDA or other 
regulatory authorities to suspend or terminate clinical trials, including as a result of a clinical hold. 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. The inability to initiate clinical trials any of our product candidates on the timeline currently anticipated or 
at all could have a material adverse effect on our business, results of operations and prospects.

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 studies 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:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

inability to generate sufficient preclinical, toxicology or other in vivo or in vitro data to support the initiation of clinical studies;

delays in sufficiently developing, characterizing or controlling a manufacturing process suitable for advanced clinical trials;

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

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

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

delays in obtaining required 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 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 it 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;

50

 
•

•

•

•

•

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 us 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.

Our timing of filing on these product candidates is dependent on further preclinical and manufacturing success, which we work on with various third 
parties. We cannot be sure that we will be able to submit our INDs in a timely manner, if at all, or 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.

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.

In our planned clinical trials of our product candidates, we have contracted with and expect to continue to 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. Medicines used at centers to help manage 
adverse  side  effects  of  ADI-001  and  ADI-002  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, any of which could have a material 
adverse effect on our ability to obtain regulatory approval and commercialize on the timelines anticipated or at all, which could have a material adverse 
effect on our business and results of operations. 

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,  including,  without  limitation,  the  impact  of  the 
ongoing  COVID-19  pandemic.  The  timely  completion  of  clinical  trials  in  accordance  with  the  protocols  depends,  among  other  things,  on  our  ability  to 
enroll a sufficient number of patients who remain in the study until the 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

51

 
•

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

We intend to conduct a number of clinical trials for product candidates in the fields of cancer in different geographies, all of which have been affected 
to varying extents by the ongoing COVID-19 pandemic. We believe that the coronavirus pandemic will have an impact on various aspects of our future 
clinical trials. For example, investigators may not want to take the risk of exposing cancer patients to COVID-19 since the dosing of patients is conducted 
within  an  in-patient  setting.  Other  potential  impacts  of  the  COVID-19  pandemic  on  our  future  various  clinical  trials  include  patient  dosing  and  study 
monitoring, which may be paused or delayed due to changes in policies at various clinical sites, federal, state, local or foreign laws, rules and regulations, 
including  quarantines  or  other  travel  restrictions,  prioritization  of  healthcare  resources  toward  pandemic  efforts,  including  diminished  attention  of 
physicians serving as our clinical trial investigators and reduced availability of site staff supporting the conduct of our clinical trials, interruption or delays 
in the operations of the government regulators, or other reasons related to the COVID-19 pandemic. It is unknown how long these pauses or disruptions 
could continue.

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 unproven 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 gamma delta T cell product candidates are based on new technologies and will require the creation of inventory of mass-produced, off-the-
shelf products, we expect that we will require extensive research and development and have substantial manufacturing and processing costs. In addition, 
costs to treat patients with NHL cancer and to treat potential side effects that may result from our product candidates can be significant. Accordingly, our 
clinical trial costs are likely to be significantly higher than for more conventional therapeutic technologies or drug products, which is expected to have a 
material adverse effect on our financial position and ability to achieve profitability.

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

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

countries, including:

•

•

•

•

•

•

•

differing regulatory requirements in foreign countries;

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

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;

52

 
•

•

•

•

•

•

•

•

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 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 potential international operations may materially adversely affect our ability to attain or maintain profitable 

operations, which could have a material adverse effect on our business and results of operations.

Risks Related to Marketing Our Product Candidates

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

The FDA often approves new therapies initially only for use in patients who are currently not adequately treated with currently approved therapies. 
We  expect  to  initially  seek  approval  of  ADI-001  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.

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,  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. 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  ADI-001.  Developing,  obtaining  regulatory 
approval  and  commercializing  additional  gamma  delta  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 it 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 which could have a material adverse effect on our business and prospects.

53

 
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 may develop a 
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 it 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. If we are unable to successfully market 
and distribute our products, our business, results of operations and prospects could be materially adversely affected.

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 in both the chimeric antigen receptor (CAR) and T cell receptor (TCR) technology space 
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  affected  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.

Risks Related to Manufacturing

We do not currently operate our own manufacturing facility and currently depend on the ability of our third-party suppliers and manufacturers with 
whom we contract to perform adequately, particularly with respect to the timely production and delivery of our product candidates, including ADI-001. 
This reliance on third parties increases the risk that we will not have sufficient quantities of our product candidates or products or such quantities at an 
acceptable cost, which could delay, prevent or impair our development or commercialization efforts. 

We do not currently own or operate any manufacturing facilities. We rely, and expect to continue to rely, on third parties for the manufacture of our 
product candidates for preclinical and clinical development. We may not be able to achieve clinical or commercial manufacturing and cell processing on 
our  own  or  through  our  contract  manufacturing  organizations  (CMOs),  including  timely  supply  of  off-the-shelf  product  to  satisfy  demands  to  support 
clinical trials of any of our product candidates. Very few companies have experience in manufacturing gamma delta T cell therapy derived from blood of 
unrelated donors and gamma delta T cells require several complex manufacturing steps before being available as a mass-produced, off-the-shelf product. 
While we believe our manufacturing and processing approaches are appropriate to support our clinical product development, we have limited experience in 
managing the allogeneic gamma delta T cell engineering process, and our allogeneic 

54

 
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 or on our behalf will result in T cells that will be safe and effective.

Our operations remain subject to review and oversight by the FDA and the FDA could object to our use of any manufacturing facilities. We must first 
receive  approval  from  the  FDA  prior  to  licensure  to  manufacture  our  product  candidates,  which  we  may  never  obtain.  Even  if  approved,  we  would  be 
subject  to  ongoing  periodic  unannounced  inspection  by  the  FDA  and  corresponding  state  agencies  to  ensure  strict  compliance  with  current  Good 
Manufacturing Practices (cGMPs) and other government regulations. Our license to manufacture product candidates will be subject to continued regulatory 
review.

Our cost of goods development is at an early stage. The actual cost to manufacture and process our product candidates could be greater than we expect 

and could materially and adversely affect the commercial viability of our product candidates.

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. 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.

Our  product  candidates  and  any  products  that  we  may  develop  may  compete  with  other  product  candidates  and  approved  products  for  access  to 
manufacturing facilities. There are a limited number of manufacturers that operate under cGMP regulations and that might be capable of manufacturing for 
us.

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, which could have a material adverse effect on our business, 
results of operations and prospects.

Risks Related to Our Operations

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.  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  the  San  Francisco  Bay  Area.  This  region  is  headquarters  to  many  other 
biopharmaceutical companies and many academic and research institutions. Competition for skilled personnel in this 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 the company, in addition to salary and cash incentives, we have provided stock options and restricted stock 
units that vest over time. The value to employees of stock options that vest over time may be significantly affected by fluctuations 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.

55

 
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 ongoing Phase 1 clinical trial 
for  ADI-001.  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, 2021, we believe that with our cash and cash equivalents we are able to fund our expenses and capital expenditure requirements 
beyond twelve months from the issuance date of the accompanying consolidated financial statements. However, 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 require additional capital for the further development and commercialization of our product candidates, including funding our 
internal manufacturing capabilities and may need to raise additional funds sooner if we choose to expand more rapidly than we presently anticipate.

We cannot be certain that additional funding will be available on acceptable terms, or at all. Other than the funding agreement and our loan agreement 
with Pacific Western Bank, 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  themselves.  Additionally,  we  may  not  be  able  to  incur  indebtedness  if  the  ongoing 
macroeconomic effects of the COVID-19 pandemic, including certain actions taken by U.S. or other governmental authorities, such as decreases in short-
term interest rates as announced by the Federal Reserve, cause the closure of banks for an extended period of time or a sudden increase in requests for 
indebtedness  at  one  time  by  many  potential  borrowers,  either  or  both  of  which  could  overwhelm  the  banking  industry.  Furthermore,  the  impact  of 
geopolitical tension, such as a deterioration in the bilateral relationship between the United States and China or an escalation in conflict between Russia and 
Ukraine, including any resulting sanctions, export controls or other restrictive actions, also could lead to disruption, instability and volatility in the global 
markets, which may have an impact on our ability to obtain additional funding.

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.

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

As our development and commercialization plans and strategies develop, and as we 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  our  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, pursuant to arrangements which expire after a certain period of time, to provide certain services, including certain research and development as 
well as general and administrative support. 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 

56

 
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, which could have a material adverse effect on our business, results of operations and prospects.

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  License  and  Collaboration  Agreement  (the  Regeneron  Agreement)  with  Regeneron 
Pharmaceuticals,  Inc.  (Regeneron)  requires  significant  research  and  development  commitments  that  may  not  result  in  the  development  and 
commercialization of product candidates. We cannot be certain that, following a strategic transaction or license, we will achieve the results, revenue or 
specific net income that justifies such transaction, which could have a material adverse effect on our business and results of operations.

Risks Related to Business Disruptions

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, such as the COVID-19 
pandemic, and other natural or man-made disasters or business interruptions. 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,  the  severity  and  frequency  of  which  may  be  amplified  by  global  climate  change,  or  other  business  interruptions.  We  have  facilities  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.

A pandemic, epidemic or outbreak of an infectious disease, such as the ongoing COVID-19 pandemic, may materially and adversely affect our business 
and operations.

Our business, financial position, results of operations or cash flows may be affected by the ongoing global COVID-19 pandemic and the resulting 
volatility and uncertainty it has caused, and is likely to continue to cause, in the United States and international markets, including as a result of prolonged 
economic downturn or recession. Since January 2020, the COVID-19 pandemic has spread around the world. The continued spread of COVID-19, despite 
progress in vaccination efforts, has resulted in significant governmental measures being implemented to control the spread of COVID-19 and its variants, 
including quarantines, travel restrictions, social distancing and business shutdowns. Such measures have had, and are likely to continue to have, adverse 
impacts on the United States economy of uncertain severity and duration and may negatively impact our operations and those of third parties on which we 
rely, including by causing disruptions in the supply of our product candidates and the conduct of current and future clinical trials. In addition, the COVID-
19  pandemic  has  affected  and  may  further  affect  the  operations  of  the  FDA  and  other  health  authorities,  which  could  result  in  delays  of  reviews  and 
approvals, including with respect to our product candidates. The ongoing COVID-19 pandemic is also likely to directly or indirectly impact the pace of 
enrollment in our future clinical trials as patients may avoid or may not be able to travel to healthcare facilities and physicians’ offices unless 

57

 
 
due to a health emergency, and clinical trial sites may be less willing to enroll patients in clinical trials that may compromise a person’s immune system. 
Such facilities and offices may also be required to focus limited resources on non-clinical trial matters, including treatment of COVID-19 patients, and may 
not be available, in whole or in part, for clinical trial services related to ADI-001 or our other product candidates. Additionally, while the ultimate economic 
impact  brought  by,  and  the  duration  of  the  COVID-19  pandemic  is  difficult  to  assess  or  predict,  the  impact  of  the  COVID-19  pandemic  on  the  global 
financial markets may reduce our ability to access capital, which could negatively impact our short-term and long-term liquidity. 

The extent to which the ongoing COVID-19 pandemic may continue to impact our business will depend on future developments, which are highly 
uncertain and cannot be predicted with confidence, such as the duration and severity of the pandemic, including the continued emergence of new variants, 
developments or perceptions regarding the safety of vaccines, or any additional preventative and protective actions taken to contain the pandemic or treat 
its impact. We do not yet know the full extent of potential delays or impacts on our business, financing, or clinical trial activities or on healthcare systems 
or the global economy as a whole. However, any of the foregoing risks, or other unforeseen risks related to the COVID-19 pandemic, could have a material 
impact on our liquidity, capital resources, operations, and business and those of the third parties on which it relies.

Inadequate funding for the FDA and other government agencies, or disruptions in their staffing levels related to the COVID-19 global pandemic, could 
hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in 
a timely manner or otherwise prevent those agencies from performing normal business functions on which the approval of our product candidates rely, 
which would 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, 
adequate staffing, furloughs, ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory, and policy changes. 
Average review times at the agency have fluctuated in recent years as a result. In addition, government funding of other government agencies on which our 
operations  may  rely,  including  those  that  fund  research  and  development  activities  is  subject  to  the  political  process,  which  is  inherently  fluid  and 
unpredictable.

Disruptions at the FDA and other agencies may also slow the time necessary for new drugs to be reviewed and/or approved by necessary government 
agencies,  which  would  adversely  affect  our  business.  For  example,  over  the  last  several  years,  including  beginning  on  December  22,  2018,  the  U.S. 
government  has  shut  down  several  times  and  certain  regulatory  agencies,  such  as  the  FDA,  have  had  to  furlough  critical  FDA  and  other  government 
employees and stop critical activities. Since March 2020 when foreign and domestic inspections of facilities were largely placed on hold, the FDA has been 
working  to  resume  routine  surveillance,  bioresearch  monitoring  and  pre-approval  inspections  on  a  prioritized  basis.  Since  April  2021,  the  FDA  has 
conducted limited inspections and employed remote interactive evaluations, using risk management methods, to meet user fee commitments and goal dates. 
Ongoing  travel  restrictions  and  other  uncertainties  continue  to  impact  oversight  operations  both  domestic  and  abroad  and  it  is  unclear  when  standard 
operational levels will resume. The FDA is continuing to complete mission-critical work, prioritize other higher-tiered inspectional needs (e.g., for-cause 
inspections), and carry out surveillance inspections using risk-based approaches for evaluating public health.  Should FDA determine that an inspection is 
necessary for approval of a marketing application and an inspection cannot be completed during the review cycle due to restrictions on travel, and the FDA 
does  not  determine  a  remote  interactive  evaluation  to  be  adequate,  FDA  has  stated  that  it  generally  intends  to  issue,  depending  on  the  circumstances,  a 
complete response letter or defer action on the application until an inspection can be completed. During the COVID-19 public health emergency, a number 
of companies announced receipt of complete response letters due to the FDA's inability to complete required inspections for their applications. Regulatory 
authorities outside the United States may adopt similar restrictions or other policy measures in response to the COVID-19 pandemic and may experience 
delays in their regulatory 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,  including  our  ability  to  access  the  public  markets  and 
obtain necessary capital in order to properly capitalize and continue our operations.

Risks Related to Healthcare Regulation

Our  relationships  with  customers,  physicians  including  clinical  investigators,  clinical  research  organizations  and  third-party  payors  are  subject, 
directly  or  indirectly,  to  federal  and  state  healthcare  fraud  and  abuse  laws,  false  claims  laws,  health  information  privacy  and  security  laws, 
transparency  laws,  government  price  reporting  and  other  healthcare  laws  and  regulations.  If  we  or  our  employees,  independent  contractors, 
consultants, commercial partners, vendors, or other agents 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 

58

 
security  of  identifiable  patient  information.  See  the  section  entitled  “Business  –  Government  Regulation  and  Product  Approval  -  Other  United  States 
Healthcare Laws and Compliance Requirements” elsewhere in this Annual Report on Form 10-K. 

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,  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 themselves 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, 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.

Data protection, privacy and similar laws restrict access, use, and disclosure of information, and failure to comply with or adapt to changes in these 
laws could materially and adversely harm our business.

We are subject to federal and state data privacy and security laws and regulations and Laws and expectations relating to privacy continue to evolve. 
Changes in these laws may limit our data access, use, and disclosure, and may require increased expenditures. In addition, data protection, privacy and 
similar laws protect more than patient information and, although they vary by jurisdiction, these laws can extend to employee information, business contact 
information, provider information, and other information relating to identifiable individuals. For example, the California Consumer Privacy Act requires 
covered businesses to, among other things, provide disclosures to California consumers regarding the collection, use and disclosure of such consumers’ 
personal  information  and  afford  such  consumers  new  rights  with  respect  to  their  personal  information,  including  the  right  to  opt  out  of  certain  sales  of 
personal  information.  In  addition,  the  CPRA  as  well  as  comprehensive  privacy  laws  in  Colorado  and  Virginia  will  become  effective  in  2023.  Further, 
numerous other states have proposed similar privacy laws. We believe that further increased regulation in additional jurisdictions is likely in the area of 
data privacy. Any of the foregoing may have a material adverse effect on our ability to provide services to patients and, in turn, our results of operations

The  collection  and  use  of  personal  data  in  the  European  Union  (EU)  are  governed  by  the  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 our processes 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.

In addition, many jurisdictions outside of Europe are also considering and/or enacting comprehensive data protection legislation. We also continue to 
see jurisdictions imposing data localization laws. These regulations may interfere with our intended business activities, inhibit our ability to expand into 
those  markets  or  prohibit  us  from  continuing  to  offer  services  in  those  markets  without  significant  additional  costs.  Because  the  interpretation  and 
application of many privacy and data protection laws (including the GDPR), commercial frameworks, and standards are uncertain, it is possible that these 
laws, frameworks, and 

59

 
standards may be interpreted and applied in a manner that is inconsistent with our existing data management practices and policies. If so, in addition to the 
possibility  of  fines,  lawsuits,  breach  of  contract  claims,  and  other  claims  and  penalties,  we  could  be  required  to  fundamentally  change  our  business 
activities  and  practices  or  modify  our  solutions,  which  could  have  an  adverse  effect  on  our  business.  Any  inability  to  adequately  address  privacy  and 
security  concerns,  even  if  unfounded,  or  comply  with  applicable  privacy  and  security  or  data  security  laws,  regulations,  and  policies,  could  result  in 
additional cost and liability to us, damage our reputation, inhibit our ability to conduct trials, and adversely affect our business

Data  protection,  privacy  and  similar  laws  protect  more  than  patient  information  and,  although  they  vary  by  jurisdiction,  these  laws  can  extend  to 
employee information, business contact information, provider information, and other information relating to identifiable individuals. Failure to comply with 
these  laws  may  result  in,  among  other  things,  civil  and  criminal  liability,  negative  publicity,  damage  to  our  reputation,  and  liability  under  contractual 
provisions. In addition, compliance with such laws may require increased costs to us or may dictate that wet not offer certain types of services in the future.

Risks Related to Litigation

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 future 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 themselves 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; and

the inability to commercialize any product candidate.

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. Assuming we obtain clinical trial insurance for our clinical trials, we may 
have to pay amounts awarded by a court or negotiated in a settlement that exceeds 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  it  to 
indemnification against losses, such indemnification may not be available or adequate should any claim arise.

60

 
Risks Related to Our Financial Position

Raising funds through lending arrangements may restrict our operations or produce other adverse results.

Our current Loan and Security Agreement with Pacific Western Bank, as amended on October 21, 2021 (the Loan Agreement), sets the interest rate of 
the term loans under the Loan Agreement at the greater of (i) 0.25% above the Prime Rate then in effect and (ii) 4.25%. The Loan Agreement contains a 
variety  of  affirmative  and  negative  covenants,  including  required  financial  reporting,  limitations  on  certain  dispositions  of  assets,  limitations  on  the 
incurrence  of  additional  debt  and  other  requirements.  To  secure  our  performance  of  our  obligations  under  this  Loan  Agreement,  we  granted  a  security 
interest in substantially all of our assets, other than certain intellectual property assets, to Pacific Western Bank and issued a warrant to purchase our capital 
stock. Our failure to comply with the covenants in the Loan Agreement, the occurrence of a material impairment in our prospect of repayment operations, 
business  or  financial  condition,  our  ability  to  repay  the  loan,  or  in  the  value,  perfection  or  priority  of  Pacific  Western  Bank’s  lien  on  our  assets,  as 
determined by Pacific Western Bank, or the occurrence of certain other specified events could result in an event of default that, if not cured or waived, 
could result in the acceleration of all or a substantial portion of our debt, potential foreclosure on our assets and other adverse results. Additionally, we are 
bound  by  certain  negative  covenants  setting  forth  actions  that  are  not  permitted  to  be  taken  during  the  term  of  the  Loan  Agreement  without  consent  of 
Pacific  Western  Bank,  including,  without  limitation,  incurring  certain  additional  indebtedness,  making  certain  asset  dispositions,  entering  into  certain 
mergers, acquisitions or other business combination transactions or incurring any non-permitted lien or other encumbrance on our assets. The foregoing 
prohibitions and constraints on our operations could result in our inability to: (a) acquire promising intellectual property or other assets on desired timelines 
or terms; (b) reduce costs by disposing of assets or business segments no longer deemed advantageous to retain; (c) stimulate further corporate growth or 
development through the assumption of additional debt; or (d) enter into other arrangements that necessitate the imposition of a lien on corporate assets. 
Moreover, if the conditions set forth in the consent provided by Pacific Western Bank are not satisfied, we would effectively need to terminate the Loan 
Agreement  and  repay  any  outstanding  loan  funds  or  refinance  the  facility  with  another  lender.  As  of  the  date  of  this  Annual  Report  on  Form  10-K,  no 
amounts have been drawn under the Loan Agreement.

Failure  to  achieve  and  maintain  effective  internal  control  over  financial  reporting  could  harm  our  business  and  negatively  impact  the  value  of  our 
common stock.

Effective  internal  control  over  financial  reporting  is  necessary  for  us  to  provide  reliable  financial  reports  and,  together  with  adequate  disclosure 
controls and procedures, are designed to prevent fraud. Any failure to implement required new or improved controls, or difficulties encountered in their 
implementation could cause us to fail to meet our reporting obligations. In addition, any testing by us conducted in connection with Section 404, or any 
subsequent testing by our independent registered public accounting firm, may reveal deficiencies in our internal control over financial reporting that are 
deemed to be material weaknesses or that may require prospective or retroactive changes to our financial statements, or may identify other areas for further 
attention or improvement. Inferior internal controls could also cause investors to lose confidence in our reported financial information, which could have a 
negative effect on the trading price of our stock.

We are required to disclose changes made in our internal controls and procedures on a quarterly basis and our management is required to assess the 
effectiveness of these controls annually. However, for as long as we are an emerging growth company (EGC) or a smaller reporting company (SRC), our 
independent registered public accounting firm will not be required to attest to the effectiveness of our internal control over financial reporting pursuant to 
Section 404. We will remain an EGC until the earliest to occur of: (1) the last day of the fiscal year in which we have more than $1.07 billion in annual 
revenue; (2) the date we qualify as a large accelerated filer, with at least $700.0 million of equity securities held by non-affiliates; (3) the date on which we 
have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period; or (4) the last day of the fiscal year ending after the 
fifth anniversary of our initial public offering, which would be December 31, 2023.
 We will qualify as a SRC if the market value of our common stock held by non-affiliates is below $250 million (or $700 million if our annual revenue is 
less than $100 million) as of June 30 in any given year. An independent assessment of the effectiveness of our internal control over financial reporting 
could detect problems that our management’s assessment might not. Undetected material weaknesses in our internal control over financial reporting could 
lead to financial statement restatements and require us to incur the expense of remediation.

We and our independent registered public accounting firm previously identified material weaknesses in our internal control over financial reporting, 
which  have  since  been  remediated.  Nevertheless,  if  we  experience  additional  material  weaknesses  or  deficiencies  in  the  future  or  otherwise  fail  to 
establish and maintain effective internal controls, we may be unable to produce timely and accurate financial statements, and we may conclude that 
our internal control over financial reporting is not effective, which could adversely impact our investors’ confidence and our stock price.

In our Annual Report on Form 10-K for the year ended December 31, 2020, we reported material weaknesses in our internal control over financial 
reporting related to deficiencies in our controls over the financial statement close process, including over complex accounting issues, expense classification 
and  accrued  research  and  development  expenses,  as  well  as  the  cash  disbursement  process.  During  2021,  we  took  a  number  of  actions  to  improve  our 
internal control over financial reporting to remediate these material weaknesses, including the hiring key personnel, implementing an Enterprise Resource 
Planning (ERP) system, and augmenting our controls to enhance our control environment. As a result of these efforts, management has concluded 

61

 
that the previously disclosed material weaknesses have been remediated as of December 31, 2021.

We expect to continue our efforts to improve our control processes, though there can be no assurance that our efforts will ultimately be successful or 
avoid potential future material weaknesses, and we expect to continue incurring additional costs as a result of these efforts. If we are unable to successfully 
remediate any future material weaknesses in our internal control over financial reporting, or if we identify any additional material weaknesses, the accuracy 
and  timing  of  our  financial  reporting  may  be  adversely  affected,  we  may  be  unable  to  maintain  compliance  with  securities  law  requirements  regarding 
timely filing of periodic reports in addition to applicable stock exchange listing requirements, investors may lose confidence in our financial reporting, and 
our stock price may decline as a result. We also could become subject to investigations by Nasdaq, the SEC or other regulatory authorities, which could 
harm our reputation and our financial condition, or divert financial and management resources from our core business.

Risks Related to Taxation

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

Under Section 382 and Section 383 of the Internal Revenue Code of 1986, as amended, or the IRC, if a corporation undergoes an “ownership change” 
(generally defined as a greater than 50 percentage point change (by value) in the ownership of its equity over a three year period), the corporation’s ability 
to use its pre-change net operating loss carryforwards and certain other pre-change tax attributes to offset its post-change income may be limited. We may 
have experienced such ownership changes in the past, and we may experience ownership changes in the future as a result of subsequent shifts in our stock 
ownership. As of December 31, 2021, we had federal net operating loss carryforwards of approximately $271.6 million, and our ability to utilize those net 
operating loss carryforwards could be limited by an “ownership change” as described above.

Comprehensive tax reform legislation could adversely affect our business and financial condition. 

The rules dealing with U.S. federal, state and local income taxation are constantly under review by persons involved in the legislative process and by 
the  Internal  Revenue  Service,  or  IRS,  and  the  U.S.  Treasury  Department.  Changes  to  tax  laws  (which  changes  may  have  retroactive  application)  could 
adversely  affect  us  or  holders  of  our  common  stock.  In  recent  years,  many  changes  have  been  made  and  changes  are  likely  to  continue  to  occur  in  the 
future. 

Additional changes to U.S. federal income tax law are currently being contemplated, and future changes in tax laws could have a material adverse 
effect on our business, cash flow, financial condition or results of operations. It cannot be predicted whether, when, in what form, or with what effective 
dates, new tax laws may be enacted, or regulations and rulings may be enacted, promulgated or issued under existing or new tax laws, which could result in 
an increase in our or our stockholders’ tax liability or require changes in the manner in which we operate in order to minimize or mitigate any adverse 
effects of changes in tax law or in the interpretation thereof. You are urged to consult your tax advisor regarding the implications of potential changes in tax 
laws on an investment in our common stock.

Risks Related to Third Parties

If our collaboration with Regeneron is terminated, or if Regeneron materially breaches its obligations thereunder, our business, prospects, operating 
results, and financial condition would be materially harmed.

Our  financial  performance  may  be  significantly  affected  by  our  Regeneron  collaboration  that  we  have  entered  into  to  develop  next-generation 
engineered  immune-cell  therapeutics  with  fully  human  CARs  and  TCRs  directed  to  disease-specific  cell  surface  antigens  in  order  to  enable  the  precise 
engagement and killing of tumor cells. Under the Regeneron Agreement, Regeneron paid us a non-refundable upfront payment of $25.0 million and an 
aggregate of $20.0 million of additional payments for research funding as of December 31, 2021, and we will collaborate with Regeneron to identify and 
validate targets and develop a pipeline of engineered immune-cell therapeutics for selected targets. Regeneron has the option to obtain development and 
commercial rights for a certain number of the product candidates developed by the parties, subject to an option payment for each product candidate. On 
January 28, 2022, we received a payment of $20.0 million from Regeneron for exercise of its option to license exclusive rights to ADI-002. If Regeneron 
exercises its option on a given product candidate, we then have an option to participate in the development and commercialization for such product. If we 
do not exercise our option, we will be entitled to royalties on any future sales of such products by Regeneron. We did not exercise our option to participate 
in the development and commercialization of ADI-002. In addition to developing CARs and TCRs for use in novel immune-cell therapies as part of the 
collaboration, Regeneron will have the right to use these CARs and TCRs in our other antibody programs outside of the collaboration. Regeneron will also 
be  entitled  to  royalties  on  any  future  sales  of  products  developed  and  commercialized  by  us  under  the  agreement.  If  Regeneron  were  to  terminate  our 
collaboration agreement with us, we may not have the resources or skills to replace those of our collaborator, which could require us to seek additional 
funding  or  another  collaboration  that  might  not  be  available  on  favorable  terms  or  at  all,  and  could  cause  significant  delays  in  development  and/or 
commercialization efforts and result in substantial additional costs to us. Termination of such collaboration agreement or the loss of rights provided to us 
under  such  agreement  may  create  substantial  new  and  additional  risks  to  the  successful  development  and  commercialization  of  our  products  and  could 
materially harm our financial condition and operating results.

62

 
Regeneron may change its strategic focus or pursue alternative technologies in a manner that results in reduced, delayed or no revenue to us under the 
agreement. Regeneron has a variety of marketed products and product candidates either by itself or under collaboration with other companies, including 
some  of  our  competitors,  and  the  corporate  objectives  of  Regeneron  may  not  be  consistent  with  our  best  interests.  Regeneron  may  change  its  position 
regarding its participation and funding of our and Regeneron joint activities, which may impact our ability to successfully pursue the program.

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

We have entered, and plan to enter, into collaborations with other companies, including our collaboration agreement with Regeneron, that we believe 
can provide us with additional capabilities beneficial to our business. The collaboration with Regeneron provides us with important technologies, expertise 
and funding for our programs and technology, and we expect to receive additional technologies, expertise and funding under this and other collaborations in 
the future. Our existing therapeutic collaborations, and any future collaborations we enter into, may pose a number of risks, including the following:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

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

collaborators may not perform their obligations as expected;

collaborators may dispute the amounts of payments owed;

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

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

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

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

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

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

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

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

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

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

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

63

 
•

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

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

In  addition  to  the  Regeneron  collaboration  described  above,  for  some  of  our  programs,  we  may  in  the  future  determine  to  collaborate  with 
pharmaceutical  and  biotechnology  companies  for  discovery,  development  and  potential  commercialization  of  therapeutic  products.  We  face  significant 
competition in seeking appropriate collaborators because, for example, third parties also have rights to allogeneic T cell technologies. For example, in April 
2020, Johnson & Johnson entered into a collaboration agreement with Fate Therapeutics, a company that is also using allogeneic T cell technologies, for up 
to four CAR Natural Killer (NK) and CAR-T cell therapies. Our ability to reach a definitive agreement for a collaboration will depend, among other things, 
upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s 
evaluation of a number of factors. If we are unable to reach agreements with suitable collaborators on a timely basis, on acceptable terms, or at all, we may 
have  to  curtail  discovery  efforts  or  the  development  of  a  product  candidate,  reduce  or  delay  our  development  program  or  one  or  more  of  our  other 
development  programs,  delay  our  potential  manufacture  or  commercialization,  or  reduce  the  scope  of  any  sales  or  marketing  activities,  or  increase  our 
expenditures  and  undertake  development  or  commercialization  activities  at  our  expense.  If  we  elect  to  fund  and  undertake  discovery,  development, 
manufacturing or commercialization activities on our own, we may need to obtain additional expertise and additional capital, which may not be available to 
us on acceptable terms or at all. If we fail to enter into collaborations and do not have sufficient funds or expertise to undertake the necessary discovery, 
development,  manufacturing  and  commercialization  activities,  we  may  not  be  able  to  further  develop  our  product  candidates,  manufacture  the  product 
candidates, bring them to market or continue to develop our technology and our business may be materially and adversely affected.

We are subject to certain exclusivity obligations under our agreement with Regeneron.

During the five-year period following the effective date of the Regeneron agreement, with certain limited exceptions, we may not directly or indirectly 
research, develop, manufacture or commercialize a gamma delta immune cell product (ICP) or grant a license to do the foregoing, except pursuant to the 
terms of the Regeneron agreement. Both parties also have obligations not to research, develop, manufacture or commercialize an ICP with the same target 
as one being developed under a research program or commercialized by a party (and royalty bearing under the agreement), for so long as such activities are 
occurring. These exclusivity obligations are limited to engineered gamma delta immune cells to targets reasonably considered to have therapeutic relevance 
in oncology. If our collaboration with Regeneron is not successful, including any failure caused by the risks listed in the preceding paragraphs, and the 
agreement and research programs are not terminated, we may not be able to enter into collaborations with other companies with respect to ICP’s and our 
business could be adversely affected.

The exclusivity obligations under the Regeneron agreement expired on July 29, 2021. Prior to this expiration date, our ability to advance any gamma 
delta immune cell therapeutics outside of the scope of the research plan agreed on with Regeneron was limited. The restrictions on internal development 
under the Regeneron agreement could lead to delays in our ability to discover and develop gamma delta immune cell therapeutics for targets not covered by 
the collaboration with Regeneron and loss of opportunities to obtain additional research funding and advance our own technologies separately from the 
Regeneron collaboration. If we are delayed in our ability to advance our technologies due to the Regeneron agreement, our business could be harmed.

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

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

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

We negotiate budgets and contracts with CROs and study sites, which may result in delays to our development timelines and increased costs. We will 
rely  heavily  on  these  third  parties  over  the  course  of  our  clinical  trials,  and  we  control  only  certain  aspects  of  their  activities.  Nevertheless,  we  are 
responsible for ensuring that each of our studies is conducted in accordance with applicable protocol, legal, regulatory and scientific standards, and our 
reliance  on  third  parties  does  not  relieve  us  of  our  regulatory  responsibilities.  We  and  these  third  parties  are  required  to  comply  with  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 

64

 
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  will  involve 
substantial cost and require extensive management time and focus. In addition, there is a natural transition period when a new third party commences work. 
As a result, delays occur, which can materially impact our ability to meet our desired clinical development timelines.

We currently 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.

We  currently  utilize,  and  expect  to  continue  to  utilize,  third  parties  to  manufacture  our  product  candidates.  If  the  field  of  cell  therapy  continues  to 
expand, we may encounter increasing competition and costs for these materials and services. Demand for third-party manufacturing in cell therapy may 
grow  at  a  faster  rate  than  existing  capacity,  which  could  disrupt  our  ability  to  find  and  retain  third-party  manufacturers  capable  of  producing  sufficient 
quantities of our product candidates at an acceptable cost or at all. We have also 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 at a commercial scale and therefore 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,  we  anticipate  reliance  on  a  limited  number  of  third-party  manufacturers  may  adversely  affect  our  operations  and  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.

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.

• 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.

65

 
• 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 third-party manufacturers could breach or terminate their agreement(s) with us.

If any CMO with whom we contract fails to perform its obligations, we may be forced to manufacture the materials ourselves, for which we may not 
have the capabilities or resources, or enter into an agreement with a different CMO, which we may not be able to do on reasonable terms, if at all. In either 
scenario, our clinical trials supply could be delayed significantly as we establish alternative supply sources. In some cases, the technical skills required to 
manufacture our product candidates may be unique or proprietary to the original CMO and we may have difficulty, or there may be contractual restrictions 
prohibiting  us  from,  transferring  such  skills  to  a  back-up  or  alternate  supplier,  or  we  may  be  unable  to  transfer  such  skills  at  all.  In  addition,  if  we  are 
required to change CMOs for any reason, we will be required to verify that the new CMO maintains facilities and procedures that comply with quality 
standards and with all applicable regulations. We will also need to verify, such as through a manufacturing comparability study, that any new manufacturing 
process will produce our product candidates according to the specifications previously submitted to the FDA or another regulatory authority. The delays 
associated with the verification of a new CMO could negatively affect our ability to develop product candidates or commercialize our products in a timely 
manner  or  within  budget.  Furthermore,  a  CMO  may  possess  technology  related  to  the  manufacture  of  our  product  candidates  that  such  CMO  owns 
independently. This would increase our reliance on such CMO or require us to obtain a license from such CMO in order to have another CMO manufacture 
our product candidates. In addition, changes in manufacturers often involve changes in manufacturing procedures and processes, which could require that 
we  conduct  bridging  studies  between  our  prior  clinical  supply  used  in  our  clinical  trials  and  that  of  any  new  manufacturer.  We  may  be  unsuccessful  in 
demonstrating the comparability of clinical supplies which could require the conduct of additional clinical trials.

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 targeting moiety and other genes to the product 
candidate.  We  currently  manufacture  through  contract  manufacturers,  some  of  which  have  limited  resources  and  experience  supporting  a  commercial 
product,  and  such  suppliers  may  not  be  able  to  deliver  raw  materials  to  our  specifications.  Those  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 do not have contracts with many of these suppliers, and we may not be able to contract with them on acceptable terms or at all. 
Accordingly, we may experience delays in receiving key raw materials to support clinical or commercial manufacturing. Additionally, since the beginning 
of  the  COVID-19  pandemic,  three  vaccines  for  COVID-19  have  received  Emergency  Use  Authorization  by  the  FDA,  and  one  of  those  later  received 
marketing approval. Additional vaccines may be authorized or approved in the future.  The resultant demand for vaccines and potential for manufacturing 
facilities and materials to be commandeered under the Defense Production Act of 1950, or equivalent foreign legislation, may make it more difficult to 
obtain materials or manufacturing slots for the materials needed for our clinical trials, which could lead to delays in these trials.

In  addition,  some  raw  materials  utilized  in  the  manufacture  of  our  candidates  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. Further, 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. We may be unable to enter into agreements with a new supplier on commercially reasonable terms, which could have a material adverse impact on 
our business.

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

Our research and development activities involve the controlled use of potentially hazardous substances, including chemical and biological materials. 
We and our suppliers are subject to federal, state and local laws and regulations in the United States governing the use, manufacture, storage, handling and 
disposal of medical and hazardous materials. Although we believe that our 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 

66

 
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.  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.

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

Our  internal  computer  systems  and  the  systems  of  our  CROs,  contractors  and  consultants  are  vulnerable  to  damage  from  computer  viruses  and 
unauthorized  access.  Additionally,  as  a  result  of  the  ongoing  COVID-19  pandemic,  we  have  transitioned  certain  of  our  workforce  to  a  remote  working 
model.  As  our  employees  and  our  business  partners’  employees  work  from  home  and  access  our  systems  remotely,  we  may  be  subject  to  heightened 
security and privacy risks, including the risks of cyberattacks and privacy incidents. 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 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.

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

We actively evaluate various strategic transactions on an ongoing basis. We may acquire other businesses, products or technologies as well as pursue 
joint ventures or investments in complementary businesses. The success of our strategic transactions, 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 have a material adverse effect on our financial condition.

Risks Related to Government Regulation

Risks Related to Regulatory Approval

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 

67

 
foreign authorities. A BLA must include extensive preclinical and clinical data and sufficient 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 product candidates 
by target, regardless of cancer type or origin, which the FDA may have difficulty accepting if our clinical trials only involved cancers of certain origins. 
The  FDA  may  also  require  a  panel  of  experts,  referred  to  as  an  Advisory  Committee,  to  deliberate  on  the  adequacy  of  the  safety  and  efficacy  data  to 
support licensure. The opinion of the Advisory Committee, although not binding, may have a significant impact on our ability to obtain licensure of the 
product  candidates  based  on  the  completed  clinical  trials,  as  the  FDA  often  adheres  to  the  Advisory  Committee’s  recommendations.  Accordingly,  the 
regulatory approval pathway for our product candidates may be uncertain, complex, expensive and lengthy, and approval may not be obtained.

We may also experience delays in obtaining regulatory approvals, including but not limited to: 

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

obtaining regulatory authorization to begin a trial, if applicable;

redesigning our study protocols and need to conduct additional studies as may be required by a regulator;

governmental  or  regulatory  delays  and  changes  in  regulation  or  policy  relating  to  the  development  and  commercialization  of  our  product 
candidate by the FDA or other comparable foreign regulatory authorities;

the outcome, timing and cost of meeting regulatory requirements established by the FDA, and other comparable foreign regulatory authorities;

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

negotiating the terms of any collaboration agreements we may choose to initiate or conclude;

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;

failure of third-party contractors, such as CROs, or investigators to comply with regulatory requirements, including GCP standards;

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

delay or failure in obtaining the necessary approvals from regulators or institutional review boards, or IRBs, in order to commence a clinical trial 
at a prospective trial site, or their suspension or termination of a clinical trial once commenced;

Inability to recruit and enroll 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;

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

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

inability to add new clinical trial sites;

varying interpretations of the data generated from our preclinical or clinical trials;

the cost of defending intellectual property disputes, including patent infringement actions brought by third parties;

the effect of competing technological and market developments;

the cost and timing of establishing, expanding and scaling manufacturing capabilities;

inability to manufacture, or obtain from third parties, sufficient quantities of qualified materials under cGMPs, for the completion in preclinical 
and clinical studies; 

problems with biopharmaceutical product candidate storage, stability and distribution resulting in global supply chain disruptions;

the cost of establishing sales, marketing and distribution capabilities for any product candidate for which we may receive regulatory approval in 
regions where we choose to commercialize our products on our own; or

potential unforeseen business disruptions or market fluctuations that delay our product development or clinical trials and increase our costs or 
expenses,  such  as  business  or  operational  disruptions,  delays,  or  system  failures  due  to  malware,  unauthorized  access,  terrorism,  war,  natural 
disasters, strikes, geopolitical conflicts, restrictions on trade, import or export restrictions, or public health crises, such as the ongoing COVID-19 
pandemic.

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, 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.  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 (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 are 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, potentially 
creating the opportunity for generic competition sooner than anticipated. Moreover, the extent to which a biosimilar, once approved, will be substituted for 
any one of the reference products in a way that is similar to traditional generic substitution for non-biological products is not yet clear, and will depend on a 
number of marketplace and regulatory factors that are still developing.

The regulatory landscape that will govern our product candidates is uncertain; regulations relating to more established 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.

Government  authorities  in  the  United  States  at  the  federal,  state  and  local  level  and  in  other  countries  regulate,  among  other  things,  the  research, 
development,  testing,  manufacture,  quality  control,  approval,  labeling,  packaging,  storage,  record-keeping,  promotion,  advertising,  distribution,  post-
approval  monitoring  and  reporting,  marketing  and  export  and  import  of  drug  and  biological  products.  Generally,  before  a  new  drug  or  biologic  can  be 
marketed, considerable data demonstrating its quality, safety and efficacy must be obtained, organized into a format specific for each regulatory authority, 
submitted for review and approved by the regulatory authority.

69

 
Because we are developing novel allogeneic cell immunotherapy product candidates, the regulatory requirements that we will be subject to are not 
entirely clear. Even with respect to more established products that fit into the category of cell therapies, the regulatory landscape is still developing. For 
example, regulatory requirements governing 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 cell therapy products.

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  somatic  cell  therapy  products  and  tissue  engineered 
products.  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  gamma  delta  CAR-T  cell  product  candidates  is  new,  we  may  face  even  more  cumbersome  and  complex 
regulations than those emerging for 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.

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 our product candidates 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 its regulatory development plans will be sufficient for submission of a BLA. 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.

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.  In  addition,  the  standard  of  care  may  change  with  the  approval  of  new  products  in  the  same  indications  that  we  are 
studying. This may result in the FDA or other regulatory agencies requesting additional studies to show that our product candidate is superior to the new 
products.

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

including the following:

•

•

•

•

•

•

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

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

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

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

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

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

70

 
•

•

the FDA or comparable foreign regulatory authorities will inspect our commercial manufacturing facility and may not approve our 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 
U.S., orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages, and 
user-fee waivers. After the FDA grants orphan drug designation, the generic identity of the drug and its potential orphan use are disclosed publicly by the 
FDA. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.

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

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  (RMAT)  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 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.

71

 
Positive results from early preclinical studies and clinical trials are not necessarily predictive of the results of any future clinical trials of our product 
candidates, and may change as more patient data becomes available and is subject to audit and verification procedures that could result in material 
changes in the final data. If we cannot replicate the positive results from our earlier preclinical studies and clinical trials of our product candidates in 
our future clinical trials, we may be unable to successfully develop, obtain regulatory approval for and commercialize our product candidate.

From  time  to  time,  we  may  publish  interim,  top-line  or  preliminary  results  from  our  preclinical  studies  or  clinical  trials.  Such  clinical  results  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. 
Preliminary or top-line results 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. 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. We also make assumptions, estimations, calculations and conclusions as part of our analyses of data, and 
we may not have received or had the opportunity to fully and carefully evaluate all data. 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 announced. As a result, interim, 
“top-line,” 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. It is also difficult to predict the timing of announcing interim results.

Accordingly, any positive results from our preclinical studies and ongoing and future clinical trials of our product candidates may not necessarily be 
predictive of the results from required later clinical trials. Similarly, even if we are able to complete our planned preclinical studies or any future clinical 
trials according to our current development timeline, the positive results from such preclinical studies and clinical trials may not be replicated in subsequent 
preclinical studies or clinical trial results.

Many  companies  in  the  pharmaceutical  and  biotechnology  industries  have  suffered  significant  setbacks  in  late-stage  clinical  trials  after  achieving 
positive results in early-stage development, and we cannot be certain that we will not face similar setbacks. These setbacks have been caused by, among 
other things, preclinical findings made while clinical trials were underway, or safety or efficacy observations made in preclinical studies and clinical trials, 
including previously unreported adverse events. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses and 
many companies that believed their product candidate performed satisfactorily in preclinical studies and clinical trials nonetheless failed to obtain FDA or 
similar regulatory approval.

If  the  clinical  updates,  or  the  interim,  "top-line",  or  preliminary  data  that  we  report  differ  from  actual  results,  or  if  others,  including  regulatory 
authorities,  disagree  with  the  conclusions  reached,  our  ability  to  obtain  approval  for  and  commercialize  our  product  candidates,  our  business,  operating 
results, prospects or financial condition may be harmed.   

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.

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.

Additionally, on June 23, 2016, the UK held a referendum in which a majority of voters approved an exit from the EU, or Brexit, and the UK formally 
left  the  EU  on  January  31,  2020.  There  was  a  transition  period  during  which  EU  pharmaceutical  laws  continued  to  apply  to  the  UK,  which  expired  on 
December 31, 2020. However, the EU and the UK have concluded a trade and cooperation agreement, or TCA, which was provisionally applicable since 
January 1, 2021 and has been formally applicable since May 1, 2021. The TCA includes specific provisions concerning pharmaceuticals, which include the 
mutual recognition of GMP, inspections of manufacturing facilities for medicinal products and GMP documents issued, but does not foresee wholesale 

72

 
mutual recognition of UK and EU pharmaceutical regulations. At present, Great Britain has implemented EU legislation on the marketing, promotion and 
sale  of  medicinal  products  through  the  Human  Medicines  Regulations  2012  (as  amended)  (under  the  Northern  Ireland  Protocol,  the  EU  regulatory 
framework  will  continue  to  apply  in  Northern  Ireland).  The  regulatory  regime  in  Great  Britain  therefore  currently  aligns  in  the  most  part  with  EU 
regulations, however it is possible that these regimes will diverge in future now that Great Britain’s regulatory system is independent from the EU and the 
TCA does not provide for mutual recognition of UK and EU pharmaceutical legislation. For example, the new Clinical Trials Regulation, which became 
effective in the EU on January 31, 2022 and provides for a streamlined clinical trial application and assessment procedure covering multiple EU Member 
States, has not been implemented into UK law, and a separate application will need to be submitted for clinical trial authorization in the UK. The separate, 
and  potentially  diverging,  regulatory  regimes  between  Great  Britain  and  the  EU  may  increase  our  regulatory  burden  of  applying  for  and  obtaining 
authorization in Great Britain and the EU.

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 post-market surveillance to monitor the safety and efficacy of the 
product candidate. The FDA may also require a risk evaluation and mitigation strategy (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 GCPs 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 cGMPs 
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's 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. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to 
have  improperly  promoted  off-label  may  be  subject  to  significant  liability.  However,  physicians  may,  in  their  independent  medical  judgment,  prescribe 
legally available products for off-label uses. The FDA does not regulate the behavior of physicians in their choice of treatments, but the FDA does restrict 
manufacturer’s  communications  on  the  subject  of  off-label  use  of  their  products.  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. 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.

73

 
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, adversely affecting our ability to achieve our commercial and financial projections.

The  use  of  engineered  gamma  delta  T  cells  as  a  potential  cancer  treatment  is  a  recent  development  and  may  not  become  broadly  accepted  by 
physicians, patients, hospitals, cancer treatment centers and others in the medical community. We expect physicians in the large bone marrow transplant 
centers to be particularly important to the market acceptance of our products and we may not be able to educate them on the benefits of using our product 
candidates for many reasons. 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 and pricing by third-party payors and government authorities;

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

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

the effectiveness of our sales and marketing efforts.

If our product candidates are approved but fail to achieve market acceptance among physicians, patients, hospitals, cancer treatment centers or others 
in the medical community, we will not be able to generate significant revenue. Even if our products achieve market acceptance, we may not be able to 
maintain that market acceptance over time if new products or technologies are introduced that are more favorably received than our products, are more cost 
effective or render our products obsolete.

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

Successful sales of our product candidates, if approved, depend on the availability of coverage and adequate reimbursement from third-party payors 
including  governmental  healthcare  programs,  such  as  Medicare  and  Medicaid,  managed  care  organizations  and  commercial  payors,  among  others. 
Significant uncertainty exists as to the coverage and reimbursement status of any product candidates for which we obtain regulatory approval. In addition, 
because our product candidates represent new approaches to the treatment of cancer, we cannot accurately estimate the potential revenue from our product 
candidates. See the section entitled “Business – Government Regulation and Product Approval – Coverage, Pricing and Reimbursement” elsewhere in this 
Annual Report on Form 10-K.

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.

74

 
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. Because our product candidate may have a higher cost of goods 
than conventional therapies, and may require long-term follow-up evaluations, the risk that coverage and reimbursement rates may be inadequate for us to 
achieve profitability may be greater. There is significant uncertainty related to insurance coverage and reimbursement of newly approved products. It is 
difficult to predict at this time what third-party payors will decide with respect to the coverage and reimbursement for our product candidate. Moreover, 
payment  methodologies  may  be  subject  to  changes  in  healthcare  legislation  and  regulatory  initiatives.  Additional  state  and  federal  healthcare  reform 
measures are expected to be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products 
and  services,  which  could  result  in  reduced  demand  for  certain  pharmaceutical  products  or  additional  pricing  pressures.  Specifically,  there  have  been 
several United States Congressional inquiries and federal and state legislation 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. We expect to experience pricing pressures in connection with the sale of any of our product candidates 
due  to  the  trend  toward  managed  healthcare,  the  increasing  influence  of  health  maintenance  organizations,  cost  containment  initiatives  and  additional 
legislative changes.

We  intend  to  seek  approval  to  market  our  product  candidates  in  both  the  United  States  and  in  selected  foreign  jurisdictions.  Increased  efforts  by 
governmental and third-party payors in the United States and abroad to cap or reduce healthcare costs may cause such organizations to limit both coverage 
and the level of reimbursement for newly approved products and, as a result, they may not cover or provide adequate payment for our product candidate. 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 EU 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. 

75

 
Even  if  favorable  coverage  and  reimbursement  status  is  attained  for  one  or  more  products  for  which  we  receive  regulatory  approval,  less  favorable 
coverage policies and reimbursement rates may be implemented in the future.

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

Third-party payors, whether domestic or foreign, or governmental or commercial, are developing increasingly sophisticated methods of controlling 
healthcare costs. In both the United States and certain foreign jurisdictions, there have been a number of legislative and regulatory changes to the health 
care system that could impact our ability to sell our product candidates, if approved, profitably. See the section entitled “Business – Government Regulation 
and Product Approval – Healthcare Reform” elsewhere in this Annual Report on Form 10-K. 

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.

 Additionally, there has been heightened governmental scrutiny in the United States of pharmaceutical and biologics pricing practices in light of the 
rising cost of prescription drugs and biologics. Such scrutiny has resulted in various congressional inquiries and proposed and enacted federal and state 
legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient 
programs, and reform government program reimbursement methodologies for products.

On July 9, 2021, President Biden issued an executive order directing the FDA to, among other things, continue to clarify and improve the approval 
framework for generic drugs and biosimilars, including the standards for interchangeability of biological products, facilitate the development and approval 
of biosimilar and interchangeable products, clarify existing requirements and procedures related to the review and submission of BLAs, and identify and 
address any efforts to impede generic drug and biosimilar competition.

We expect that additional U.S. federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that the U.S. 
Federal  Government  will  pay  for  healthcare  drugs  and  services,  which  could  result  in  reduced  demand  for  our  drug  candidates  or  additional  pricing 
pressures.  Individual  states  in  the  United  States  have  also  become  increasingly  active  in  passing  legislation  and  implementing  regulations  designed  to 
control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain drug access 
and  marketing  cost  disclosure  and  transparency  measures,  and  designed  to  encourage  importation  from  other  countries  and  bulk  purchasing.  Legally 
mandated price controls on payment amounts by third-party payors or other restrictions could harm our business, financial condition, results of operations 
and  prospects.  In  addition,  regional  healthcare  authorities  and  individual  hospitals  are  increasingly  using  bidding  procedures  to  determine  what 
pharmaceutical  products  and  which  suppliers  will  be  included  in  their  prescription  drug  and  other  healthcare  programs.  This  could  reduce  the  ultimate 
demand  for  our  drugs  or  put  pressure  on  our  drug  pricing,  which  could  negatively  affect  our  business,  financial  condition,  results  of  operations  and 
prospects. 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 it believes 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

Risks Related to Our Intellectual Property

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.

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

countries, as appropriate. However, we cannot predict:

•

•

•

•

if and when patents will issue;

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

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

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

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

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

77

 
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.

We may require access to additional intellectual property to develop our current or future product candidates. Accordingly, the growth of our business 

will likely depend in part on our ability to acquire, in-license or use these proprietary rights.

Our product candidates may also require specific formulations to work effectively and efficiently and these rights may be held by others. We may be 
unable  to  acquire  or  in-license  any  compositions,  methods  of  use,  processes  or  other  third-party  intellectual  property  rights  from  third  parties  that  we 
identify. 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 our patent applications at risk of not issuing. Defense of these claims, regardless of their merit, would 
involve substantial litigation expense and would be a substantial diversion of employee resources from our business. 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.

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.

78

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

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

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.

Risks Related to Third Party 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  Regeneron.  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. To the extent these licensors fail to meet their obligations under their 
license agreements, which we are not in control of, we may lose the benefits of our license agreements with these licensors. In the future, we may also enter 
into additional license agreements that are material to the development of our product candidates.

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

•

•

•

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

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

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

79

 
•

•

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.

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.

Our  commercial  success  depends  in  part  on  us  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 United States 
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.

We are aware of United States and foreign patents held by a third parties relating to gamma delta T cell expansion protocols and related compositions 
which, on information and belief, are invalid and/or not infringed. In the event that these patents are successfully asserted against our product candidates, 
such  as  ADI-001  and  ADI-002,  or  the  use  of  our  precursor  cells  in  manufacture  of  these  product  candidates,  such  litigation  may  negatively  impact  our 
ability to commercialize these product candidates in such jurisdictions. We are also aware of several United States and foreign patents held by third parties 
relating to certain CAR compositions of matter, methods of making and methods of use which, on information and belief, are invalid and/or not infringed. 
Nevertheless, third parties may assert that we infringe their patents or are otherwise employing their proprietary technology without authorization and may 
sue us. Generally, conducting clinical trials and other development activities in the United States is not considered an act of infringement. If and when ADI-
001 or ADI-002 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 and/or not 
infringed.

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 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 

80

 
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.

Risks Related to Intellectual Property Laws

Changes in United States 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 United States Court of Appeals for the Federal Circuit and 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 United States 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.

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 U.S., 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 it develops 
or licenses.

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 

81

 
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

Risks Related to Ownership Generally

An active trading market for our common stock may not be sustained. If an active trading market is not sustained, our ability to raise capital in the 
future may be impaired.

Our shares began trading on The Nasdaq Global Select Market on January 26, 2018. Given the limited trading history of our common stock, there is a 
risk that an active trading market for our shares may not be sustained, which could put downward pressure on the market price of our common stock and 
thereby affect your ability to sell shares you purchased. An inactive trading market for our common stock may also impair our ability to raise capital to 
continue to fund our operations by selling shares and impair our ability to acquire other companies or technologies by using our shares as consideration.

The trading price of our common stock highly volatile, which could result in substantial losses for purchasers of our common stock. Securities class 
action or other litigation involving our company or members of our management team could also substantially harm our business, financial condition 
and results of operations.

Our stock price is highly volatile. The stock market in general and the market for smaller pharmaceutical and biotechnology companies in particular 
have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. As a result of this volatility, you 
may not be able to sell your common stock at or above the purchase price and you may lose some or all of your investment. The market price for our 
common stock may be influenced by many factors, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

the success of existing or new competitive products or technologies; 

regulatory actions with respect to our product candidates or our competitors’ products and product candidates;

announcements  by  us  or  our  competitors  of  significant  acquisitions,  strategic  partnerships,  joint  ventures,  collaborations  or  capital 
commitments;

the timing and results of clinical trials of ADI-001 in NHL; 

commencement or termination of collaborations for our development programs;

failure or discontinuation of any of our development programs;

results of clinical trials of product candidates of our competitors;

regulatory or legal developments in the United States and other countries;

developments or disputes concerning patent applications, issued patents or other proprietary rights;

the recruitment or departure of key personnel;

the level of expenses related to any of our product candidates or clinical development programs;

the results of our efforts to develop additional product candidates or products;

actual or anticipated changes in estimates as to financial results or development timelines;

announcement or expectation of additional financing efforts;

sales of our common stock by us, our insiders or other stockholders;

variations in our financial results or those of companies that are perceived to be similar to us;

changes in estimates or recommendations by securities analysts, if any, that cover us;

changes in the structure of healthcare payment systems;

market conditions in the pharmaceutical and biotechnology sectors;

general economic, industry and market conditions; and

the other factors described in this “Risk Factors” section.

82

 
In the past, securities class action litigation has often been brought against a company following a decline in the market price of its securities. This risk 

is especially relevant for biopharmaceutical companies, which have experienced significant stock price volatility in recent years.

Our principal stockholders and management own a significant percentage of our stock and will be able to exert significant control over matters subject 
to stockholder approval.

Our executive officers, directors, and 5% stockholders beneficially owned, in the aggregate, approximately 42.2% of our outstanding voting common 
stock.  Accordingly,  these  stockholders  will  have  the  ability  to  influence  us  through  this  ownership  position  and  significantly  affect  the  outcome  of  all 
matters  requiring  stockholder  approval.  For  example,  these  stockholders  may  be  able  to  significantly  affect  the  outcome  of  elections  of  directors, 
amendments  of  our  organizational  documents,  or  approval  of  any  merger,  sale  of  assets,  or  other  major  corporate  transaction.  This  may  prevent  or 
discourage unsolicited acquisition proposals or offers for our common stock that you may feel are in your best interest as one of our stockholders.

Risks Related to Market Uncertainties

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.  We  believe  that  the  state  of  global  economic  conditions  are  particularly  volatile  and  uncertain,  not  only  in  light  of  the  COVID-19 
pandemic and the potential global recession resulting therefrom, but also due to recent and expected shifts in political, legislative and regulatory conditions 
concerning, among other matters, international trade and taxation, and that an uneven recovery or a renewed global downturn may negatively impact our 
ability to conduct clinical trials on the scale and timelines anticipated. 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 or political environment or continued unpredictable and unstable market conditions. If the current equity and credit markets deteriorate, it may 
make  obtaining  any  necessary  debt  or  equity  financing  more  difficult,  more  costly  and  more  dilutive.  For  example,  as  a  result  of  political,  social,  and 
economic instability abroad, including as a result of armed conflict, war or threat of war, in particular, the current conflict between Russia and Ukraine, 
including resulting sanctions, terrorist activity and other security concerns in general, there could be a significant disruption of global financial markets, 
impairing  our  ability  to  raise  capital  when  needed  on  acceptable  terms,  if  at  all.    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. To the extent that our profitability 
and strategies are negatively affected by downturns or volatility in general economic conditions, our business and results of operations may be materially 
adversely affected.

Risks Related to our Charter and Bylaws

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 third 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 the holders of not less than 75% of the votes that all our stockholders would be entitled 
to cast in an annual election of directors;

83

 
•

•

a requirement of approval of not less than 75% of all outstanding shares of our voting stock to amend any bylaws by stockholder action or to 
amend specific provisions of our certificate of incorporation; and

the authority of the board of directors to issue preferred stock on terms determined by the board of directors without stockholder approval and 
which preferred stock may include rights superior to the rights of the holders of common stock.

In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporate Law, 
which may prohibit certain business combinations with stockholders owning 15% or more of our outstanding voting stock. These anti-takeover provisions 
and  other  provisions  in  our  amended  and  restated  certificate  of  incorporation  and  amended  and  restated  bylaws  could  make  it  more  difficult  for 
stockholders or potential acquirors to obtain control of our board of directors or initiate actions that are opposed by the then-current board of directors and 
could also delay or impede a merger, tender offer or proxy contest involving our company. These provisions could also discourage proxy contests and make 
it more difficult for you and other stockholders to elect directors of your choosing or cause us to take other corporate actions you desire. Any delay or 
prevention of a change of control transaction or changes in our board of directors could cause the market price of our common stock to decline.

Our amended and restated bylaws provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the 
State of Delaware will be the sole and exclusive forum for most legal actions between us and our stockholders, which could limit our stockholders’ 
ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.

Our amended and restated bylaws specifies that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the 
State  of  Delaware  will  be  the  sole  and  exclusive  forum  for  (i)  any  derivative  action  or  proceeding  brought  on  behalf  of  the  Company,  (ii)  any  action 
asserting  a  claim  of  breach  of  a  fiduciary  duty  owed  by  any  director,  officer  or  other  employee  of  the  Company  to  the  Company  or  the  Company’s 
stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law or the restated certificate of 
incorporation  or  amended  and  restated  bylaws,  or  (iv)  any  action  asserting  a  claim  against  the  Company  governed  by  the  internal  affairs  doctrine.  This 
choice  of  forum  provision  contained  in  our  amended  and  restated  bylaws  will  not  apply  to  any  causes  of  action  arising  under  the  Securities  Act  or  the 
Exchange Act. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock shall be deemed to have notice of and to 
have consented to the provisions of our amended and restated bylaws described above; provided, however, that stockholders cannot and will not be deemed 
to have waived our compliance with the U.S. federal securities laws and the rules and regulations thereunder.

We believe this provision benefits us by providing increased consistency in the application of Delaware law by chancellors particularly experienced in 
resolving corporate disputes, efficient administration of cases on a more expedited schedule relative to other forums and protection against the burdens of 
multi-forum litigation. However, the provision may have the effect of discouraging lawsuits against our directors, officers, employees and agents as it may 
limit  any  stockholder’s  ability  to  bring  a  claim  in  a  judicial  forum  that  such  stockholder  finds  favorable  for  disputes  with  us  or  our  directors,  officers, 
employees  or  agents.  The  enforceability  of  similar  choice  of  forum  provisions  in  other  companies’  bylaws  or  certificates  of  incorporation  has  been 
challenged in legal proceedings, and it is possible that, in connection with any applicable action brought against us, a court could find the choice of forum 
provisions contained in our amended and restated bylaws to be inapplicable or unenforceable in such action. If a court were to find the choice of forum 
provision contained in our amended and restated bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with 
resolving such action in other jurisdictions, which could adversely affect our business, financial condition or results of operations.

General Risk Factors

We are an EGC and the reduced disclosure requirements applicable to EGCs may make our common stock less attractive to investors.

We are an EGC, and, for as long as we continue to be an EGC, we may choose to take advantage of exemptions from various reporting requirements 
applicable to other public companies but not to “emerging growth companies.” We will remain an EGC until the earliest to occur of: (1) the last day of the 
fiscal year in which we have more than $1.07 billion in annual revenue; (2) the date we qualify as a large accelerated filer, with at least $700.0 million of 
equity  securities  held  by  non-affiliates;  (3)  the  date  on  which  we  have  issued  more  than  $1.0  billion  in  non-convertible  debt  securities  during  the  prior 
three-year  period;  and  (4)  the  last  day  of  the  fiscal  year  ending  after  the  fifth  anniversary  of  our  initial  public  offering.  For  as  long  as  we  remain  an 
“emerging growth company,” we expect to avail ourselves of the exemptions from various reporting requirements applicable to other public companies but 
not  to  EGCs,  including  not  being  required  to  comply  with  the  auditor  attestation  requirements  of  Section  404  of  the  Sarbanes-Oxley  Act  of  2002,  as 
amended (Section 404).

84

 
Assuming we do not surpass one of the thresholds in clauses (1) through (3), our status as an EGC will end on December 31, 2023, which will be the last 
day of the fiscal year ending after the fifth anniversary of our initial public offering. As such, we will be subject to the disclosure requirements applicable to 
other public companies that were not applicable to us as an EGC. These requirements include:

•

•

•

•

compliance with the auditor attestation requirements of Section 404;

compliance with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm 
rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;

full disclosure obligations regarding executive compensation; and

compliance with the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden 
parachute payments not previously approved.

When our independent registered public accounting firm is required to undertake an assessment of our internal control over financial reporting, the cost of 
our compliance with Section 404 will correspondingly increase. Moreover, if we are not able to comply with the requirements of Section 404 applicable to 
us in a timely manner, or if we or our independent registered public accounting firm identifies deficiencies in our internal control over financial reporting 
that are deemed to be material weaknesses, the market price of our stock could decline and we could be subject to sanctions or investigations by the SEC or 
other  regulatory  authorities.  Additionally,  we  expect  that  our  loss  of  EGC  status  will  require  additional  attention  from  management  and  will  result  in 
increased costs to us, which could include higher legal fees, accounting fees and fees associated with investor relations activities, among others.

We are also a SRC and the reduced disclosure requirements applicable to SRCs may make our common stock less attractive to investors.

We are considered a SRC under Rule 12b-2 of the Exchange Act. We are therefore entitled to rely on certain reduced disclosure requirements, such as 
an  exemption  from  providing  selected  financial  data  and  executive  compensation  information.  These  exemptions  and  reduced  disclosures  in  our  SEC 
filings due to our status as a smaller reporting company also mean our auditors are not required to review our internal control over financial reporting and 
may make it harder for investors to analyze our results of operations and financial prospects. 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  common  stock  prices  may  be  more  volatile.  We  will  remain  a  smaller  reporting  company  until  our  public  float 
exceeds $250 million or our annual revenues exceed $100 million with a public float greater than $700 million.

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

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

We  do  not  anticipate  paying  any  cash  dividends  on  our  capital  stock  in  the  foreseeable  future.  Accordingly,  stockholders  must  rely  on  capital 
appreciation, if any, for any return on their investment.

We  have  never  declared  nor  paid  cash  dividends  on  our  capital  stock.  We  currently  plan  to  retain  all  of  our  future  earnings,  if  any,  to  finance  the 
operation, development and growth of our business. In addition, the terms of any future debt or credit agreements may preclude us from paying dividends. 
As a result, capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our share 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 one or more of the analysts who cover us issues an adverse opinion about our company, our stock price would likely decline. If one or more of 
these analysts ceases research coverage of us or fails to regularly publish 

85

 
reports on us, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline.

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 could occur at any time. These sales, or the perception in the market 
that holders of a large number of shares intend to sell shares, could reduce the market price of our common stock. Certain holders of our common stock 
have rights, subject to conditions, to require us to file registration statements covering their shares or to include their shares in registration statements that 
we may file for ourselves or other stockholders. Registration of these shares under the Securities Act of 1933, as amended (Securities Act) would result in 
the  shares  becoming  freely  tradable  without  restriction  under  the  Securities  Act,  except  for  shares  held  by  affiliates,  as  defined  in  Rule  144  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.

On March 12, 2021, we filed a registration statement on Form S-3 (File No. 333-254193) with the SEC, which was declared effective on March 30, 
2021  (Shelf  Registration  Statement),  in  relation  to  the  registration  of  common  stock,  preferred  stock,  debt  securities,  warrants  and/or  units  of  any 
combination thereof for the purposes of selling, from time to time, our common stock, debt securities or other equity securities in one or more offerings. We 
also simultaneously entered into a Capital On Demand™ Sales Agreement (Sales Agreement) with JonesTrading Institutional Services, LLC (Sales Agent), 
to provide for the offering, issuance and sale of up to an aggregate amount of $75.0 million of our common stock from time to time in “at-the-market” 
offerings under the Shelf Registration Statement and subject to the limitations thereof. The Company will pay to the Sales Agent cash commissions of 3% 
of the aggregate gross proceeds of sales of common stock under the Sales Agreement. Sales of common stock, debt securities or other equity securities by 
us may represent a significant percentage of our common stock currently outstanding. If we sell, or the market perceives that we intend to sell, substantial 
amounts of our common stock under the Shelf Registration Statement or otherwise, the market price of our common stock could decline significantly.

We also filed a registration statement on Form S-8 registering the issuance of shares of common stock issued or reserved for future issuance under our 
equity compensation plans. Shares registered under this registration statement on Form S-8 can be freely sold in the public market upon issuance and once 
vested, subject to volume limitations applicable to affiliates and the lock-up agreements described above. If any of these additional shares are sold, or if it is 
perceived that they will be sold, in the public market, the market price of our common stock could decline.

In addition, certain of our employees, executive officers, and directors may enter into Rule 10b5-1 trading plans providing for sales of shares of our 
common stock from time to time. Under a Rule 10b5-1 trading plan, a broker executes trades pursuant to parameters established by the employee, director, 
or officer when entering into the plan, without further direction from the employee, officer, or director. A Rule 10b5-1 trading plan may be amended or 
terminated in some circumstances. Our employees, executive officers, and directors also may buy or sell additional shares outside of a Rule 10b5-1 trading 
plan when they are not in possession of material, nonpublic information.

Item 1B. Unresolved Staff Comments.

Not applicable.

Item 2. Properties.

We have offices in Boston, Massachusetts, and Menlo Park, California. Our principal executive offices are located at 200 Clarendon, Floor 6, Boston, 

Massachusetts 02116. The original term of this lease expires on March 31, 2022, and was renewed in February 2022 to expire on July 31, 2022. We also 
leased office and laboratory space located in Menlo Park, California. The lease expires on June 30, 2022. In addition, in October 2018, we entered a new 
lease for office and laboratory space in Redwood City, California that expires on February 28, 2030. We expect to complete occupancy in the new facility 
in the fourth quarter of 2022. We believe that our office and laboratory space is sufficient to meet our current needs and that suitable additional space will 
be available as and when needed.

Item 3. Legal Proceedings.

We are not currently subject to any material legal proceedings. From time to time, we may be subject to various legal proceedings and claims that 
arise in the ordinary course of our business activities. Although the results of litigation and claims cannot be predicted with certainty, as of the date of this 
report, we do not believe we are party to any claim or litigation the outcome of which, if determined adversely to us, would individually or in the aggregate 
be reasonably expected to have a material adverse effect on our business. Regardless of the 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.

PART II 

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities. 

Our common stock trades on The Nasdaq Global Market under the symbol “ACET”. Trading of our common stock commenced on January 26, 2018, 

in connection with our initial public offering of resTORbio. Prior to that time, there was no established public trading market for our common stock. 

As of March 10, 2022, we had approximately 24 holders of record of our common stock. The actual number of holders of our common stock is greater 
than this number of record holders and includes stockholders who are beneficial owners, but whose shares are held in street name by brokers or held by 
other nominees. This number of holders of record also does not include stockholders whose shares may be held in trust by other entities.

Dividends

We have never declared or paid any cash dividends on our common stock. We currently intend to retain all available funds and any future earnings, if 
any, to fund the development and growth of our business. We do not expect to pay any cash dividends in the foreseeable future. Any future determination to 
pay  dividends  will  be  made  at  the  discretion  of  our  board  of  directors  and  will  depend  on  various  factors,  including  applicable  laws,  our  results  of 
operations, financial condition, future prospects, then applicable contractual restrictions and any other factors deemed relevant by our board of directors. 
Investors should not purchase our common stock with the expectation of receiving cash dividends.

Equity Compensation Plan 

The information required by Item 5 of Form 10‑K regarding equity compensation plans is incorporated herein by reference to Item 12 of Part III of 

this Annual Report on Form 10‑K. 

Recent Sales of Unregistered Securities

Securities Purchase Agreement

On February 12, 2021, we entered into a stock purchase agreement with certain existing investors for $15.0 million of shares of our common stock, 
with an initial closing for certain investors held simultaneously with the closing of our February 2021 public offering and a subsequent closing for certain 
additional investors. Pursuant to the terms of the private placement, we issued 1,153,840 shares of common stock at a price of $13.00 per share, which was 
the price per share of our February 2021 public offering (the Private Placement Shares). We received the full proceeds from the sale and did not pay any 
underwriting discounts or commissions with respect to the shares of common stock that sold in the concurrent private placement. Proceeds from the private 
placement  will  be  used  primarily  to  fund  activities  related  to  our  internal  discovery  research,  other  pipeline  candidates  and  to  fund  the  continued 
development of our gamma delta T cell platform; the external costs for the development of ADI-001 through the completion of a Phase 1 dose expansion 
study for ADI-001 in NHL; and the remainder, if any, to fund working capital and other general corporate purposes. The private placement was exempt 
from registration pursuant to Section 4(a)(2) of the Securities Act as a transaction by an issuer not involving a public offering. Pursuant to the terms of the 
private  placement,  we  subsequently  filed  a  Registration  Statement  on  Form  S-3  (File  No.  333-256088),  dated  May  21,  2021,  pursuant  to  which  we 
registered the Private Placement Shares. We have agreed to maintain the effectiveness of the registration statement until such time as all Private Placement 
Shares  covered  by  the  registration  statements  have  been  sold  or  may  be  sold  under  Rule  144  without  manner  of  sale  restrictions  or  volume  limitations, 
subject to certain exceptions.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. 

You should read the following discussion and analysis of our financial condition and results of operations together with our consolidated financial 
statements and related notes included elsewhere in this Annual Report on Form 10-K. This discussion and other parts of this Annual Report on Form 10-K 
contain  forward-looking  statements  that  involve  risks  and  uncertainties,  such  as  our  plans,  objectives,  expectations,  intentions  and  beliefs.  Our  actual 
results could differ materially from those discussed in these forward-looking statements. Factors that could cause or contribute to such differences include, 
but are not limited to, those identified below and those discussed in the section entitled “Risk Factors” included elsewhere in this Annual Report on Form 
10-K.

Overview 

We are a clinical stage biotechnology company discovering and developing allogeneic gamma delta T cell therapies for cancer. We are advancing a 
pipeline of “off-the-shelf” gamma delta T cells, engineered with chimeric antigen receptors (CAR) and T cell receptor-like antibodies (TCRL), to enhance 
selective tumor targeting, facilitate innate and adaptive anti-tumor immune response, and improve persistence for durable activity in patients. Our approach 
to activate, engineer and manufacture allogeneic gamma delta T cell product candidates derived from the peripheral blood cells of unrelated donors allows 
us to generate new product candidates in a rapid and cost-efficient manner. 

Our lead product candidate, ADI-001, a first-in-class allogeneic gamma delta T cell therapy expressing a CAR targeting CD20, is in an ongoing Phase 
1  study  for  the  treatment  of  Non-Hodgkin's  Lymphoma  (NHL).  Our  pipeline  also  includes  ADI-002,  an  allogeneic  gamma  delta  CAR-T  cell  therapy 
expressing a GPC3-targeted CAR and a cell intrinsic soluble form of interluiken-15 (IL-15), for the treatment of solid tumors In addition, we are engaged 
in  discovery  and  preclinical  stage  activities  directed  to  expansion  of  our  pipeline  of  product  candidates  for  both  hematological  malignancies  and  solid 
tumors.

Our proprietary engineering and manufacturing process begins with isolating and expanding gamma delta T cells from the blood of unrelated donors, 
and results in the potential to treat up to 1,000 patients per batch depending on dosing and the CAR target. The potential to administer product candidates 
based on gamma delta T cells to patients without inducing a graft versus host immune response could mean that our products can potentially be used as 
“off-the-shelf” therapies. This is in contrast to products based on alpha beta T cells, which either must be manufactured for each patient from his or her own 
T cells, or require significant gene editing to manufacture if the T cells are derived from donors that are unrelated to the patient. Based on what we believe 
is  the  unique  potential  of  these  cells  and  associated  modifications,  we  are  initially  developing  product  candidates  in  oncology,  both  for  hematological 
malignancies  and  for  solid  tumors.  In  October  2020,  the  U.S.  Food  and  Drug  Administration  (FDA)  cleared  our  Investigational  New  Drug  (IND) 
application  for  ADI-001,  our  lead  product  candidate,  for  the  treatment  of  Non-Hodgkin’s  Lymphoma  (NHL).  In  March  2021,  we  initiated  the  first-in-
human clinical trial to assess safety and efficacy of ADI-001 in NHL patients. The Phase 1 study for ADI-001 will enroll up to 80 late-stage NHL patients 
at a number of cancer centers across the United States. The study includes a dose escalation portion followed by dose expansion cohorts to explore the 
activity of ADI-001 in multiple subtypes of NHL. In December 2021, we announced positive interim clinical data from the initial dose escalation portion of 
this study.

Recent Developments

Public Offerings and Private Placement

In  February  2021,  we  completed  an  underwritten  public  offering  of  10,575,513  shares  of  our  common  stock,  including  the  exercise  in  full  by  the 
underwriters  of  their  option  to  purchase  up  to  an  additional  1,344,743  shares  of  common  stock  at  a  public  offering  price  of  $13.00  per  share.  The  net 
proceeds from the offering, after deducting underwriting discounts and commissions and offering expenses were approximately $128.8 million.

In connection with the February 2021 offering, we also entered into a stock purchase agreement with certain existing investors to purchase 1,153,840 
shares  of  our  common  stock  for  $15.0  million  at  a  price  per  share  equal  to  the  public  offering  price,  with  an  initial  closing  for  certain  investors  held 
simultaneously with the closing of the offering and a subsequent closing for certain additional investors. We received the full proceeds from the sale and 
did not pay any underwriting discounts or commissions with respect to the shares of common stock that sold in the concurrent private placement. Pursuant 
to the terms of the private placement, we subsequently filed a Registration Statement on Form S-3 (File No. 333-256088), dated May 21, 2021, pursuant to 
which we registered the Private Placement Shares. We have agreed to maintain the effectiveness of the registration statement until such time as all Private 
Placement  Shares  covered  by  the  registration  statements  have  been  sold  or  may  be  sold  under  Rule  144  without  manner  of  sale  restrictions  or  volume 
limitations, subject to certain exceptions.

In  December  2021,  we  completed  an  underwritten  public  offering  of  7,187,500  shares  of  our  common  stock,  including  the  exercise  in  full  by  the 
underwriters  of  their  option  to  purchase  up  to  an  additional  937,500  shares  of  common  stock,  at  a  public  offering  price  of  $14.00  per  share.  The  net 
proceeds from the offering, after deducting underwriting discounts and commissions and offering expenses were approximately $94.2 million.

At-the-Market (ATM) Offering

On March 12, 2021, we entered into a Sales Agreement (the 2021 Sales Agreement) with JonesTrading Institutional Services (the Agent), pursuant to 
which we could sell, from time to time, at our option, up to an aggregate of $75.0 million of shares of our common stock, through the Agent, as our sales 
agent. No shares were sold under the 2021 Sales Agreement as of December 31, 2021. In connection with the 2021 Sales Agreement, we terminated a prior 
ATM program with Evercore Group L.L.C. and H.C. Wainwright & Co., L.L.C.

Loan Agreement

On  October  21,  2021,  we  amended  our  Loan  and  Security  Agreement  (the  Loan  Agreement)  with  Pacific  Western  Bank    (PacWest)(the  Loan 
Amendment) under which PacWest will provide one or more Term Loans, as well as Non-Formula Ancillary Services which shall not exceed $5.5 million 
in the aggregate. Non-Formula Ancillary Services are defined as automated clearinghouse transactions, corporate credit card services, letters of credit, or 
other treasury management services. The aggregate sum of the outstanding Term Loans and Non-Formula Ancillary Services shall at no time exceed $15.0 
million, which each Term Loan to be in an amount of not less than $1.0 million. As of December 31, 2021, we had outstanding Non-Formula Ancillary 
Services  of  $4.4  million.  Accordingly,  as  of  December  31,  2021,  the  Company  has  $10.6  million  available  under  the  Term  Loan.  Pursuant  to  the  Loan 
Amendment, the interest rate for the Term Loans shall be set at an annual rate equal to the greater of (i) 0.25% above the Prime Rate then in effect and (ii) 
4.25%.

As of the date of this Annual Report on Form 10-K, we were in compliance with such covenants and had no indebtedness outstanding under the Loan 

Agreement.

Impact of COVID-19 Pandemic

In December 2019, a novel strain of coronavirus, COVID-19, was reported in China. The spread of COVID-19 from China to other countries has 
resulted  in  the  World  Health  Organization  (WHO)  declaring  the  outbreak  of  COVID-19  as  a  “pandemic,”  or  a  worldwide  spread  of  a  new  disease,  on 
March 11, 2020. Since then, COVID-19 has spread globally and new variants of the virus have emerged. Many countries around the world have imposed 
quarantines and restrictions on travel and mass gatherings to slow the spread of the virus and have closed non-essential businesses. The continued spread of 
COVID-19, despite progress in vaccination efforts, has resulted in significant governmental measures being implemented to control the spread of COVID-
19 and its variants. These measures may result in a period of business, supply, and drug product manufacturing disruption, and in reduced operations, any 
of which could materially affect our business, financial condition and results of operations.

In  response  to  the  COVID-19  pandemic,  we  tasked  members  of  our  Executive  Leadership  team,  Human  Resources,  Facilities  and  Operations  and 
Employee Communications to develop guidelines and processes intended to raise awareness of new health and well-being protocols and potentially helpful 
practices for cross-functional teamwork for our employees. We implemented remote working and shift scheduling, provided our team members practical 
recommendations based on guidelines from the Centers for Disease Control and Prevention, State of California Department of Health Care Services, State 
of  Massachusetts  Department  of  Public  Health,  OSHA  and  other  regional  government  entities.  In  addition,  we  are  committed  to  updating  these 
recommendations and communicating new pertinent information when available. While doing so we are sensitive to ensuring any guidance provided may 
vary by locality based on government orders and regulations.

Thus far we have not experienced a significant disruption or delay in our operations as it relates to the clinical development of our drug candidates. 
However, we anticipate that the impact of the COVID-19 pandemic may create difficulties in our clinical trials for a variety of reasons, including future 
regulations  regarding,  or  the  inability  or  unwillingness  of  patients  to,  travel  to  participate  in  clinical  trials,  or  to  participate  in  clinical  trials  that  are 
administered  in  medical  facilities  that  also  treat  COVID-19,  potential  delays  in  the  FDA’s  review  and  approval  processes  and/or  shortages  of  medical 
supplies that may force medical professionals to focus on non-clinical procedures, including treatment of COVID-19. The duration and ultimate impact of 
the ongoing COVID-19 pandemic on clinical trials generally, and on our trials particularly, is currently unknown.

In addition, the spread of COVID-19, which has caused a broad impact globally, may materially affect us economically. While the potential economic 
impact brought by, and the duration of, COVID-19 may be difficult to assess or predict, a widespread pandemic could result in significant disruption of 
global financial markets, reducing our ability to access capital, which could in the future negatively affect our liquidity. In addition, a recession or market 
correction resulting from the spread of COVID-19 and its variants could materially affect our business. Possible effects may also include absenteeism in 
our  labor  workforce,  unavailability  of  products  and  supplies  used  in  operations,  and  a  decline  in  value  of  assets  held  by  us,  including  property  and 
equipment, and marketable debt securities.

Financial Operations Overview 

Revenue 

We  have  no  products  approved  for  commercial  sale  and  do  not  expect  to  generate  revenue  from  product  sales  unless  and  until  we  successfully 
complete  development  and  obtain  regulatory  approval  for  our  product  candidates,  which  we  expect  will  not  be  for  at  least  several  years,  if  ever.  Our 
revenues  to  date  are  generated  from  our  License  and  Collaboration  Agreement  with  Regeneron  Pharmaceuticals,  Inc.  (Regeneron)  and  the  agreement 
referred to as the “Regeneron Agreement”. The primary purpose of the Regeneron Agreement is to establish a strategic relationship to identify and validate 
appropriate  targets  and  work  together  to  develop  a  pipeline  of  engineered  immune  cell  products  (Collaboration  ICPs)  for  the  selected  targets.  The 
Regeneron  Agreement  provides  for  the  following:  (i)  licenses  to  our  technology,  (ii)  research  and  development  services,  (iii)  services  or  obligations  in 
connection with participation in the research committee, (iv) information sharing, and (v) manufacturing services to manufacture of Collaboration ICPs for 
the  research  programs.  The  Regeneron  Agreement  provides  Regeneron  an  option  to  obtain  an  exclusive,  royalty-bearing  development  and  commercial 
license under our intellectual property to develop and commercialize the optioned Collaboration ICPs ready for an IND submission.

We received a non-refundable upfront payment of $25.0 million from Regeneron upon execution of the Regeneron Agreement on July 29, 2016 and 
have received an aggregate of $20.0 million of additional payments for research funding from Regeneron as of December 31, 2020. In addition, Regeneron 
may  have  to  pay  us  additional  amounts  in  the  future  consisting  of  up  to  an  aggregate  of  $80.0  million  of  option  exercise  fees  for  a  certain  number  of 
Collaboration ICPs. On January 28, 2022, we received a payment of $20.0 million from Regeneron for exercise of its option to license exclusive rights to 
ADI-002 and Regeneron potentially has additional options to other Collaboration ICP targets under the Regeneron Agreement. We declined to exercise our 
option to co-fund the development of ADI-002 with Regeneron, and accordingly, Regeneron must also pay us high single digit royalties as a percentage of 
net sales for ADI-002 or any other optioned ICPs to targets for which it has exclusive rights and low single digit royalties as a percentage of net sales on 
any  non-ICP  product  comprising  a  target  generated  by  us  through  the  use  of  Regeneron’s  proprietary  mice.  We  must  pay  Regeneron  mid-single  to  low 
double digit royalties as a percentage of net sales of Collaboration ICPs to targets for which we have exercised exclusive rights, and low to mid-single digit 
royalties as a percentage of net sales of targeting moieties generated from our license to use Regeneron’s proprietary mice. Royalties are payable until the 
longer of the expiration or invalidity of the licensed patent rights or 12 years from first commercial sale.

We use a cost-based input method to measure proportional performance and to calculate the corresponding amount of revenue to recognize under the 
Regeneron Agreement. In applying the cost-based input method of revenue recognition, we use actual costs incurred relative to budgeted costs to fulfill the 
combined  performance  obligation.  Revenue  is  recognized  based  on  actual  costs  incurred  as  a  percentage  of  total  budgeted  costs  as  we  complete  our 
performance obligations over the research term of five years. A cost-based input method of revenue recognition requires us to estimate costs to complete 
our performance obligations, which requires significant judgment to evaluate assumptions related to cost estimates. The cumulative effect of revisions to 
estimated costs to complete our performance obligations is recorded in the period in which changes are identified and amounts can be reasonably estimated.

Operating Expenses

Research and Development 

Research  and  development  expenses,  which  consist  primarily  of  costs  incurred  in  connection  with  the  development  of  our  product  candidates,  are 

expensed as incurred. Research and development expenses consist primarily of:

•

•

•

•

employee related costs, including salaries, benefits and stock-based compensation expenses for research and development employees;

costs incurred under agreements with consultants, contract manufacturing organizations (CMOs) and contract research organizations (CROs);

lab materials, supplies, and maintenance of equipment used for research and development activities; and

allocated facility-related costs, such as rent, utilities, insurance, repairs and maintenance, depreciation and amortization, information technology 
costs and general support services.

We  do  not  allocate  our  costs  by  product  candidate,  as  a  significant  amount  of  research  and  development  expenses  are  not  tracked  by  product 
candidate, and we believe the allocation of such costs would be arbitrary and would not provide a meaningful assessment as we have used our employee 
and infrastructure resources across multiple product candidate research and development programs.

91

 
We are focusing substantially all of our resources on the development of our product candidates. At this time, we cannot reasonably estimate or know 
the nature, timing and estimated costs of the efforts that will be necessary to complete the development of our product candidates. We are also unable to 
predict when, if ever, material net cash inflows will commence from sales 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, including:

•

•

•

•

•

•

•

•

•

•

•

the scope, rate of progress and expense of clinical trials and other research and development activities;

clinical trial results;

uncertainties in clinical trial enrollment rate or design;

significant and changing government regulation;

the timing and receipt of any regulatory approvals;

the FDA’s or other regulatory authority’s influence on clinical trial design;

establishing commercial manufacturing capabilities or making arrangements with third-party manufacturers;

commercializing product candidates, if and when approved, whether alone or in collaboration with others;

obtaining and maintaining patent and trade secret protection and regulatory exclusivity for product candidates;

continued applicable safety profiles of the products following approval; and

retention of key research and development personnel.

A change in the outcome of any of these variables with respect to the development of a product candidate could significantly change the costs, timing 
and viability associated with the development of that product candidate. For example, if the FDA, or another regulatory authority, were to require us to 
conduct clinical trials beyond those that it currently anticipates will be required for the completion of clinical development of a product candidate, or if we 
experience significant delays in enrollment in any of our clinical trials, we could be required to expend significant additional financial resources and time 
on the completion of clinical development. Furthermore, we are unable to predict when or if our product candidates will receive regulatory approval with 
any certainty.

We are focusing substantially all of our resources on the development of our product candidates. We expect our research and development expenses to 
increase  substantially  during  the  next  few  years,  as  we  seek  to  initiate  clinical  trials  for  our  product  candidates,  complete  our  clinical  program,  pursue 
regulatory  approval  of  our  product  candidates  and  prepare  for  a  possible  commercial  launch.  Predicting  the  timing  or  the  cost  to  complete  our  clinical 
program or validation of our commercial manufacturing and supply processes is difficult and delays may occur because of many factors, including factors 
outside of our control. For example, if the FDA or other regulatory authorities were to require us to conduct clinical trials beyond those that we currently 
anticipate, or if we experience significant delays in enrollment in any of our clinical trials, we could be required to expend significant additional financial 
resources  and  time  on  the  completion  of  clinical  development.  Furthermore,  we  are  unable  to  predict  when  or  if  our  product  candidates  will  receive 
regulatory approval with any certainty.

General and Administrative

General and administrative expenses consist principally of payroll and personnel expenses, including salaries and bonuses, benefits and stock-based 
compensation  expenses,  professional  fees  for  legal,  consulting,  accounting  and  tax  services,  allocated  overhead  expenses,  including  rent,  equipment, 
depreciation,  information  technology  costs  and  utilities,  and  other  general  operating  expenses  not  otherwise  classified  as  research  and  development 
expenses.

We anticipate that our general and administrative expenses will increase for the foreseeable future due to anticipated expenses related to the Merger 
and future expenses related to operating as a public company, including expenses related to personnel costs, expanded infrastructure and higher consulting, 
legal and accounting services costs associated with complying with the applicable Nasdaq and SEC requirements, investor relations costs and director and 
officer insurance premiums.

Interest Income

Interest income consists primarily of interest income earned on our cash and cash equivalents and marketable debt securities.

92

 
Interest Expense

Interest expense consists primarily of the non-cash amortization of costs incurred in connection with the Loan Agreement entered into with PacWest 

in April 2020, and subsequently amended in October 2021.

Other Income (Expense), Net

In 2020, other income (expense), net primarily consists of changes in the fair value of our redeemable convertible preferred stock tranche liability and 
redeemable convertible preferred stock warrant liability prior to their conversion to warrants to purchase common stock upon closing of the Merger. In 
2021, other income (expense), net primarily consists of state franchise and capital taxes not related to income.

Revenue decreased by $8.2 million, or 46%, for the year ended December 31, 2021 compared to the year ended December 31, 2020 resulting from the 
decrease in revenue recognized under the Regeneron Agreement. This decrease in revenue was primarily due to our achievement of a milestone under the 
Regeneron Agreement in June 2020 relating to the selection of a clinical candidate for ADI-002. This resulted in an increase in the transaction price of 
$10.0 million and recognition of an additional cumulative catch-up of revenue of $5.0 million in June 2020.

Research  and  development  expenses  increased  by  $14.6  million,  or  43%,  during  the  year  ended  December  31,  2021  compared  to  the  year  ended 
December 31, 2020. The increase in research and development expenses was primarily due to an increase of $5.8 million in personnel expenses, including 
salaries, benefits, and bonuses due to increases in headcount of employees involved in research and development activities, as well as an increase in stock-
based compensation expense of $3.1 million due to higher option grant activity. In addition, there was an increase of $3.7 million in fees incurred for CRO, 
CMO, consultants, and other externally sponsored research and $4.9 million increase in facility and other expenses. This increase was primarily due to 
ramping up of clinical development activities related to ADI-001, our leading product candidate.

General and administrative

General and administrative expenses decreased by $0.5 million, or 2%, during the year ended December 31, 2021 as compared to the same period in 
2020.  The  decrease  in  general  and  administrative  expenses  was  primarily  due  to  a  decrease  of  $6.3  million  in  professional  fees  primarily  related  to 
decreases of $5.1 million in legal fees and $1.7 million in audit fees, due to higher expenses associated with the Merger in 2020. 

These  decreases  in  professional  fees  were  offset  by  an  increase  of  $0.5  million  in  other  professional  fees  consisting  of  investor  relations,  IT 
management,  and  other  enterprise  solutions.  In  addition,  the  decreases  in  general  and  administrative  expenses  were  offset  by  a  $3.1  million  increase  in 
payroll and personnel expenses, which includes salaries, benefits, bonuses, and temporary contractor fees due to higher stock-based compensation expenses 
of $4.2 million caused by increased option grant activity and higher salaries and benefits of $1.0 million reduced by lower temporary contractor fees of 
$2.2 million. 

Further, there was an increase of $2.8 million in facilities and other expenses, primarily related to rent, depreciation costs, and director and officer 

liability insurance. 

Interest income

Interest income decreased by $0.7 million, or 88%, during the year ended December 31, 2021 compared to the year ended December 31, 2020, which 
was primarily attributable to the decrease in average balance of marketable debt securities in 2021 and decrease in interest rates, which lowered return on 
investments.

Interest Expense

Interest expense increased by less than $0.1 million during the year ended December 31, 2021 as compared to the same period in 2020 due to the non-

cash amortization of costs incurred in connection with the Loan Agreement that was entered in April 2020 and subsequently amended in October 2021. 

Other income (expense), net

Other income (expense), net decreased by $0.3 million, or 36%, during the year ended December 31, 2021 compared to the year ended December 31, 
2020. The decrease was primarily due to a realized gain recognized in 2020 related to a change in fair value of the redeemable preferred stock warrant 
liability prior to their conversion to warrants to purchase common stock upon closing of the Merger in September 2020 offset by $0.2 million related to the 
derecognition  of  fixed  assets  related  to  the  sublease  of  the  Boston  lease  in  August  2021,  $0.6  million  of  franchise  taxes,  and  less  than  $0.1  million  of 
realized loss due to foreign exchange.

Income tax expense (benefit)

We recognized an income tax benefit of $0.1 million during the year ended December 31, 2021 compared to the income tax benefit of $2.8 million for 
the year ended December 31, 2020. The reduction in benefit relates to the nature of discrete tax benefit during the year ended December 31, 2020, as a 
result of the recognition of a net operating loss carryback under the CARES Act. Income tax benefit of $0.1 million for the year ended December 31, 2021 
was  primarily  due  to  the  tax  effect  of  the  reduction  in  the  deferred  tax  liability  associated  with  the  basis  differences  from  in-process  research  and 
development (IPR&D). 

Liquidity and Capital Resources

As of December 31, 2021, our principal source of liquidity was cash and cash equivalents, which totaled $277.5 million. Our net losses were $62.0 

million and $36.7 million for the years ended December 31, 2021 and 2020, respectively.

Sources of Liquidity

Since our formation in 2014, we have funded our operations with an aggregate of $116.3 million in gross cash proceeds from the sale of redeemable 
convertible  preferred  stock  and  an  aggregate  of  $45.0  million  received  to  date  from  Regeneron  under  the  Regeneron  Agreement.  In  September  2020, 
following the closing of the Merger, all outstanding shares of the redeemable 

94

 
convertible preferred stock converted into 12,048,671 shares of common stock. We also acquired $64.1 million of cash, cash equivalents, and restricted 
cash owned by resTORbio, as part of the Merger.

In  February  2021,  we  completed  an  underwritten  public  offering  of  10,575,513  shares  of  our  common  stock,  including  the  exercise  in  full  by  the 
underwriters  of  their  option  to  purchase  up  to  an  additional  1,344,743  shares  of  common  stock,  at  a  public  offering  price  of  $13.00  per  share.  The  net 
proceeds  from  the  offering,  after  deducting  underwriting  discounts  and  commissions  and  offering  expenses  were  approximately  $128.8  million.  In 
connection with the offering, we also entered into a stock purchase agreement with certain existing investors to purchase 1,153,840 shares of our common 
stock  for  $15.0  million  at  a  price  per  share  equal  to  the  public  offering  price,  with  an  initial  closing  for  certain  investors  held  simultaneously  with  the 
closing of the offering and a subsequent closing for certain additional investors.

In  December  2021,  we  completed  an  underwritten  public  offering  of  7,187,500  shares  of  our  common  stock,  including  the  exercise  in  full  by  the 
underwriters  of  their  option  to  purchase  up  to  an  additional  937,500  shares  of  common  stock,  at  a  public  offering  price  of  $14.00  per  share.  The  net 
proceeds from the offering, after deducting underwriting discounts and commissions and offering expenses were approximately $94.2 million.

Loan Agreement

On October 21, 2021, we amended the Loan Agreement with PacWest (the Loan Amendment) under which PacWest will provide one or more Term 
Loans, as well as Non-Formula Ancillary Services which shall not exceed $5.5 million in the aggregate. Non-Formula Ancillary Services are defined as 
automated  clearinghouse  transactions,  corporate  credit  card  services,  letters  of  credit,  or  other  treasury  management  services.  The  aggregate  sum  of  the 
outstanding Term Loans and Non-Formula Ancillary Services shall at no time exceed $15.0 million, which each Term Loan to be in an amount of not less 
than $1.0 million. As of December 31, 2021, we had outstanding Non-Formula Ancillary Services of $4.4 million. Accordingly, as of December 31, 2021, 
the Company has $10.6 million available under the Term Loan. Pursuant to the Loan Amendment, the interest rate for the Term Loans shall be set at an 
annual rate equal to the greater of (i) 0.25% above the Prime Rate then in effect and (ii) 4.25%.

As of the date of this Annual Report on Form 10-K, we were in compliance with such covenants and had no indebtedness outstanding under the Loan 

Agreement.

At-the-Market (ATM) Offering

On March 12, 2021, we entered into the 2021 Sales Agreement with the Agent, pursuant to which we could sell, from time to time, at our option, up to 
an aggregate of $75.0 million of shares of our common stock, through the Agent, as our sales agent. No shares were sold under the 2021 Sales Agreement 
as of December 31, 2021.

Future Funding Requirements

We have incurred losses since inception and have incurred losses of $62.0 million and $36.7 million for the years ended December 31, 2021 and 2020, 

respectively. As of December 31, 2021, we had an accumulated deficit of $168.3 million.

As of December 31, 2021, we had cash and cash equivalents of $277.5 million. We believe that our cash and cash equivalents will be sufficient for us 
to continue as a going concern for at least 12 months from the issuance date of our consolidated financial statements as of and for the year ended December 
31, 2021 included elsewhere in this Annual Report on Form 10-K. We have based these estimates on assumptions that may prove to be wrong, and we 
could  deplete  our  available  capital  resources  sooner  than  we  expect.  Because  of  the  risks  and  uncertainties  associated  with  research,  development,  and 
commercialization of product candidates, we are unable to estimate the exact amount of our working capital requirements. 

All of our revenue to date is generated from the Regeneron Agreement, which is a collaboration and license agreement. We do not expect to generate 
any  significant  product  revenue  until  we  obtain  regulatory  approval  of  and  commercialize  any  of  our  product  candidates  or  enter  into  additional 
collaborative agreements with third parties, and we do not know when, or if, either will occur. We expect to continue to incur significant losses for the 
foreseeable future, and we expect the losses to increase as we continue the development of, and seek regulatory approvals for, our product candidates and 
begin to commercialize any approved products. We are subject to all of the risks typically related to the development of new product candidates, and we 
may encounter unforeseen expenses, difficulties, complications, delays, and other unknown factors that may adversely affect our business.

We will continue to require additional capital to develop our product candidates and fund operations for the foreseeable future. We may seek to raise 

capital through private or public equity or debt financings, collaborative or other arrangements with 

95

 
 
 
 
corporate sources, or through other sources of financing. We anticipate that we will need to raise substantial additional capital, the requirements for which 
will depend on many factors, including:

•

•

•

•

•

•

•

•

•

•

•

•

the scope, timing, rate of progress and costs of our drug discovery efforts, preclinical development activities, laboratory testing and clinical trials 
for our product candidates;

the number and scope of clinical programs we decide to pursue;

the cost, timing and outcome of preparing for and undergoing regulatory review of our product candidates;

the scope and costs of development and commercial manufacturing activities;

the cost and timing associated with commercializing our product candidates, if they receive marketing approval;

the extent to which we acquire or in-license other product candidates and technologies;

the  costs  of  preparing,  filing  and  prosecuting  patent  applications,  maintaining  and  enforcing  our  intellectual  property  rights  and  defending 
intellectual property-related claims;

our ability to establish and maintain collaborations on favorable terms, if at all;

our  efforts  to  enhance  operational  systems  and  our  ability  to  attract,  hire  and  retain  qualified  personnel,  including  personnel  to  support  the 
development of our product candidates and, ultimately, the sale of our products, following FDA approval;

our implementation of operational, financial and management systems;

the impact of the COVID-19 pandemic on United States and global economic conditions that may impact our ability to access capital on terms 
anticipated, or at all; and

the post-merger costs associated with being a public company.

A  change  in  the  outcome  of  any  of  these  or  other  variables  with  respect  to  the  development  of  any  of  our  product  candidates  could  significantly 
change the costs and timing associated with the development of that product candidate. Furthermore, our operating plans may change in the future, and we 
will continue to require additional capital to meet operational needs and capital requirements associated with such operating plans.

Adequate  funding  may  not  be  available  to  us  on  acceptable  terms  or  at  all.  Our  failure  to  raise  capital  as  and  when  needed  could  have  a  negative 
impact  on  our  financial  condition  and  our  ability  to  pursue  our  business  strategies.  If  we  are  unable  to  raise  additional  funds  when  needed,  we  may  be 
required to delay, reduce, or terminate some or all of our development programs and clinical trials or we may also be required to sell or license to other 
rights to our product candidates in certain territories or indications that we would prefer to develop and commercialize ourselves. If we are required to enter 
into  collaborations  and  other  arrangements  to  supplement  our  funds,  we  may  have  to  give  up  certain  rights  that  limit  our  ability  to  develop  and 
commercialize our product candidates or may have other terms that are not favorable to us or our stockholders, which could materially affect our business 
and financial condition.

See the section of this Annual Report on Form 10-K titled “Risk Factors” for additional risks associated with our substantial capital requirements.

Cash Flows from Operating Activities

The use of cash in all periods resulted primarily from our net losses adjusted for non-cash charges and changes in components of working capital. The 
increases  in  cash  used  in  operating  activities  for  the  years  ended  December  31,  2021  and  2020  were  primarily  due  to  increased  external  research  and 
development expenses as we continue to develop our product candidates, and increased internal and external expenses related to the initiation of our Phase 
1 clinical trial. Higher costs associated with increased employee headcount related to expanded development activities also contributed to the increase in 
cash used in operating activities.

These factors were partially offset by lower professional services costs in 2021. Non-cash charges for the year ended December 31, 2021 also include 
$12.5 million of stock-based compensation expense, compared to $5.3 million for the year ended December 31, 2020. The changes in prepaid expenses and 
other current assets, accounts payable, and accrued and other liabilities resulted from the timing of payments to our service providers.

We  currently  lease  an  office  space  in  Boston,  MA  under  a  non-cancellable  operating  lease  (the  Boston  Lease),  with  an  expiration  date  of  July  31, 
2026. The Boston Lease was amended on April 1, 2019, to relocate into a premises in the same building with additional space. The initial annual base rent 
for this lease was $0.6 million and increases 2% annually. On July 19, 2021, we subleased the office space in Boston, MA. The term of the sublease started 
on  September  1,  2021  and  will  end  on  July  30,  2026.  The  aggregate  base  rent  due  to  us  under  the  Sublease  Agreement  is  approximately  $3.5  million. 
Pursuant to the Sublease Agreement, we agreed to transfer certain furniture located in the subleased premises to the sublessee for $1.00. We remain liable 
for the lease payments under the Boston Lease.

We also have an office facility in Menlo Park, CA under a non-cancellable operating lease (the Menlo Park Lease), with an expiration date of March 
31, 2022 (subject to any optional extension). This lease was amended on June 25, 2021 to extend the term of lease from March 31, 2022 to June 30, 2022 
and replace the previously leased premises (known as 173 and 175-177 Jefferson Drive) with a nearby premises (known as 235 Constitution Drive). The 
lease commenced on July 15, 2021 and expires on June 30, 2022. In connection with these changes, we incur monthly rent payments ranging from $87,286 
to $89,904, increasing over the remaining term of the lease. This lease was amended on September 30, 2019 to include additional office space, with an 
expiration date of March 31, 2022 (subject to any optional extension). The initial annual base rent for the Menlo Park Lease is an aggregate of $1.0 million, 
and  such  amount  will  increase  3%  annually.  On  October  28,  2018,  we  executed  an  additional  non-cancelable  lease  agreement  for  a  new  office  and 
laboratory  facility  in  Redwood  City,  CA  (the  Redwood  City  Lease),  with  an  expiration  date  of  February  28,  2030.  The  initial  annual  base  rent  for  the 
Redwood City Lease is an aggregate of $1.3 million, and such amount will increase 3% annually.

On July 30, 2021, we entered a short-term lease agreement with the Boston Properties, Inc. for a temporary office space located at 200 Clarendon 
Street, Boston, MA. The initial lease term commenced on July 30, 2021 and expire on November 30, 2021. In October 2021, we extended the lease term to 
March 31, 2022 and most recently, in February 2022, extended the lease term to July 31, 2022. The base rent is less than $0.1 million per month.

Cash Flows from Investing Activities

Net cash used in investing activities was $2.8 million for the year ended December 31, 2021, which consisted of purchases of property and equipment 
of $13.0 million related to the construction of our new building in Redwood City, CA, partially offset by proceeds from sales and maturities of marketable 
debt securities of $10.3 million.

Net  cash  provided  by  investing  activities  was  $115.2  million  for  the  year  ended  December  31,  2020,  which  consisted  of  cash  and  restricted  cash 
acquired  in  connection  with  the  Merger  of  $64.1  million,  proceeds  from  maturities  of  marketable  debt  securities  of  $57.8  million,  partially  offset  by 
purchases of marketable debt securities of $5.7 million and purchases of property and equipment of $1.0 million.

Cash Flows from Financing Activities

Net cash provided by financing activities was $242.7 million for the year ended December 31, 2021, which was related to net cash proceeds received 
from our public offerings and concurrent private placement in February 2021 and December 2021 of  $238.1 million, and cash proceeds of $4.8 million 
from exercise of stock options and purchases under our Employee Stock Purchase Plan (ESPP), offset by debt issuance costs of approximately $0.2 million.

Net cash provided by financing activities was $0.3 million for the year ended December 31, 2020, due to cash proceeds of $0.5 million from exercise of 
stock options partly offset by payment of debt issuance costs of $0.2 million.

Critical Accounting Policies, Significant Judgments and Use of Estimates

Our discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been 
prepared in accordance with GAAP. The preparation of our consolidated financial statements requires us to make estimates and judgments that affect the 
reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities in our consolidated financial statements. 
Actual results may differ from these estimates under different assumptions or conditions and could have a material impact on our reported results. While 
our significant accounting policies are more fully described in the Notes to our consolidated financial statements included elsewhere in this Annual Report 
on Form 10-K, we believe the following accounting policies to be the most critical in understanding the judgments and estimates we use in preparing our 
consolidated financial statements:

Revenue Recognition

We  earn  all  of  our  revenue  in  connection  with  our  license  and  collaboration  agreement  with  Regeneron,  which  allows  Regeneron  to  utilize  our 

technology and know-how to develop product candidates.

For elements of collaboration arrangements that are accounted for pursuant to ASC Topic 606, Revenue from Contracts with Customers, or ASC 606, 
we  identify  the  performance  obligations  and  allocate  the  total  consideration  we  expect  to  receive  on  a  relative  standalone  selling  price  basis  to  each 
performance  obligation.  Key  assumptions  to  determine  the  standalone  selling  price  may  include  forecasted  revenues,  development  timelines, 
reimbursement rates for personnel costs, the expected number of targets or indications expected to be pursued, discount rates and probabilities of technical 
and regulatory success. 

We recognize revenue associated with each performance obligation as the control over the promised goods or services transfer to our collaboration 
partner which occurs either at a point in time or over time. If control transfers over time, revenue is recognized by using a method of measuring progress 
that best depicts the transfer of goods or services, for example based on actual costs incurred relative to total forecasted costs to be incurred over the period 
the transfer of goods or services occurs. We evaluate the measure of progress and related inputs each reporting period and any resulting adjustments to 
revenue  are  recorded  on  a  cumulative  catch-up  basis.  Revenue  to  be  recognized  is  equal  to  the  total  transaction  price  multiplied  by  the  ratio  of  actual 
expense incurred divided by total forecasted expense.

Accrued CMO, CRO, and Research and Development Expenses

We have entered into various agreements with CMOs and CROs. Our research and development accruals are estimated based on the level of services 
performed, progress of the studies, including the phase or completion of events, and contracted costs. The estimated costs of research and development 
provided,  but  not  yet  invoiced,  are  included  in  accrued  and  other  current  liabilities  on  the  consolidated  balance  sheet.  If  the  actual  timing  of  the 
performance of services or the level of effort varies from the original estimates, we will adjust the accrual accordingly. Payments made to CMOs and CROs 
under  these  arrangements  in  advance  of  the  performance  of  the  related  services  are  recorded  as  prepaid  expenses  and  other  current  assets  on  the 
consolidated balance sheets until the services are rendered. To date, our estimated accruals have not differed materially from the actual costs.

Stock-Based Compensation

We  use  a  fair  value-based  method  to  account  for  all  stock-based  compensation  arrangements  with  employees  and  non-employees,  including  stock 
options  and  restricted  stock  awards.  Our  determination  of  the  fair  value  of  stock  options  on  the  date  of  grant  utilizes  the  Black-Scholes  option  pricing 
model. The fair value of the option granted is recognized on a straight-line basis over the period during which an optionee is required to provide services in 
exchange for the option award, known as the requisite service period, which usually is the vesting period. For awards that have a performance condition, 
the  Company  recognizes  compensation  expense  based  on  its  assessment  of  the  probability  that  the  performance  condition  will  be  achieved,  using  an 
accelerated attribution model, over the explicit or implicit service period. We account for forfeitures as they occur. In determining fair value of the stock 
options granted, we use the Black–Scholes option-pricing model, which requires the input of subjective assumptions. These assumptions include estimating 
the length of time employees will retain their vested stock options before exercising them (expected term), the estimated volatility of our common stock 
price over the expected term (expected volatility), risk-free interest rate and expected dividends. Changes in the following assumptions can materially affect 
the  estimate  of  fair  value  and  ultimately  how  much  stock-based  compensation  expense  is  recognized;  and  the  resulting  change  in  fair  value,  if  any,  is 
recognized  in  our  consolidated  statement  of  operations  and  comprehensive  loss  during  the  period  the  related  services  are  rendered.  These  inputs  are 
subjective and generally require significant analysis and judgment to develop. Changes in the following assumptions can materially affect the estimate of 
the fair value of stock-based compensation:

•

Expected  Term  —  The  expected  term  is  calculated  using  the  simplified  method  which  is  used  when  there  is  insufficient  historical  data  about 
exercise patterns and post-vesting employment termination behavior. The simplified method is based on the vesting period and the contractual 
term  for  each  grant,  or  for  each  vesting-tranche  for  awards  with  graded  vesting.  The  mid-point  between  the  vesting  date  and  the  maximum 
contractual expiration date is used as the expected term under this method. For awards with multiple vesting-tranches, the times from grant until 
the mid-points for each of the tranches may be averaged to provide an overall expected term.

98

 
•

•

•

Expected Volatility — The Company has limited trading history. As such, the expected volatility was determined by examining the historical 
volatilities of a peer group of comparable publicly traded companies in biotechnology and pharmaceutical related industries to be representative 
of our expected future stock price volatility. For purposes of identifying these peer companies, we consider the industry, stage of development, 
size and financial leverage of potential comparable companies. For each grant, we measure historical volatility over a period equivalent to the 
expected term. 

Risk-Free  Interest  Rate  —  The  risk-free  interest  rate  is  based  on  the  implied  yield  currently  available  on  United  States  Treasury  zero-coupon 
issues with a remaining term equivalent to the expected term of the stock award.

Expected Dividend Rate — We have not paid and does not anticipate paying dividends in the near future. Accordingly, we estimate the dividend 
yield to be zero.

Common Stock Valuations

Prior to our Merger, the estimated fair value of the common stock underlying our stock options and stock awards was determined at each grant date by 
our board of directors, with assistance from management and external appraisers. All options to purchase shares of our common stock were intended to be 
exercisable at a price per share not less than the per-share fair value of our common stock underlying those options on the date of grant. The approach to 
estimate the fair value of our common stock was consistent with the methods outlined in the American Institute of Certified Public Accountants’ Practice 
Aid,  Valuation  of  Privately-Held-Company  Equity  Securities  Issued  as  Compensation  (Practice  Aid).  Subsequent  to  the  Merger,  the  fair  value  of  our 
common stock is determined based on the closing market price.

Emerging Growth Company and Smaller Reporting

In April 2012, the Jumpstart Our Business Startups Act of 2012 (the JOBS Act) was enacted. Section 107 of the JOBS Act provides that an emerging 
growth company (EGC), can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended, or 
the Securities Act, for complying with new or revised accounting standards. Thus, an EGC can delay the adoption of certain accounting standards until 
those standards would otherwise apply to private companies. 

We have elected to use the extended transition period for new or revised accounting standards during the period in which we remain an emerging 
growth company; however, we may adopt certain new or revised accounting standards early. We will remain an emerging growth company until the earliest 
to occur of: (1) the last day of the fiscal year in which we have more than $1.07 billion in annual revenue; (2) the date we qualify as a large accelerated 
filer, with at least $700.0 million of equity securities held by non-affiliates; (3) the date on which we have issued more than $1.0 billion in non-convertible 
debt securities during the prior three-year period; and (4) last day of the fiscal year ending after the fifth anniversary of our initial public offering, which 
would be December 31, 2023.

We are also a smaller reporting company meaning that the market value of our stock held by non-affiliates is less than $700 million and our annual 
revenue was less than $100 million during the most recently completed fiscal year. We may continue to be a smaller reporting company if either (i) the 
market value of our stock held by non-affiliates is less than $250 million or (ii) our annual revenue was less than $100 million during the most recently 
completed fiscal year and the market value of our stock held by non-affiliates is less than $700 million. If we are a smaller reporting company at the time 
we cease to be an emerging growth company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller 
reporting  companies.  Specifically,  as  a  smaller  reporting  company  we  may  choose  to  present  only  the  two  most  recent  fiscal  years  of  audited  financial 
statements  in  our  Annual  Report  on  Form  10-K  and,  similar  to  emerging  growth  companies,  smaller  reporting  companies  have  reduced  disclosure 
obligations regarding executive compensation.

Recently Issued and Adopted Accounting Pronouncements

See the section titled “Summary of Significant Accounting Policies” in Note 2 to our financial statements included elsewhere in this Annual Report on 

Form 10-K for additional information.

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

Interest Rate Risk

As of December 31, 2021, we had cash and cash equivalents of $277.5 million, which consisted of cash and money market funds. Interest income is 
sensitive to general level of interest rates; however, due to the nature of these investments, an immediate 10% change in interest rates would not have a 
material impact on our cash and cash equivalents, financial position, or results of operations.

99

 
Foreign Currency Exchange Risk

Our headquarters are located in the United States, where a majority of our general and administrative expenses and research and development costs 
are  incurred  in  U.S.  Dollars.  As  we  grow  our  business,  our  results  of  operations  and  cash  flows  may  be  subject  to  fluctuations  due  to  foreign  currency 
exchange rates. To date, we do not believe foreign currency exchange rate fluctuations have had a significant impact on our results of operations for any 
periods presented herein.

Inflation Risk

Our assets are primarily monetary, consisting of cash and cash equivalents. Because of their liquidity, these assets are not directly affected by inflation. 
Since  we  intend  to  retain  and  continue  to  use  our  equipment,  furniture,  fixtures  and  office  equipment,  computer  hardware  and  software  and  leasehold 
improvements,  we  believe  that  the  incremental  inflation  related  to  replacement  costs  of  such  items  will  not  materially  affect  our  operations.  Inflation 
generally  affects  us  by  increasing  our  cost  of  labor,  clinical  trial  and  manufacturing  costs.  We  do  not  believe  that  inflation  had  a  material  effect  on  our 
business, financial condition or results of operations during the years ended December 31, 2021 and 2020.

Item 8. Financial Statements and Supplementary Data.

All financial statements and supplementary data required to be filed hereunder are filed as listed under Item 15(a) of this Annual Report on Form 10-K 

and are incorporated herein by this reference. 

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.

None.

Item 9A. Controls and Procedures.

Evaluation of disclosure controls and procedures

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer (our principal executive officer and principal 
financial  officer,  respectively),  evaluated  the  effectiveness  of  our  disclosure  controls  and  procedures  as  of  December  31,  2021.  The  term  "disclosure 
controls and procedures," as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are 
designed  to  ensure  that  information  required  to  be  disclosed  by  a  company  in  the  reports  that  it  files  or  submits  under  the  Exchange  act  is  recorded, 
processed, summarized and reported, within the time periods specified in the SEC's rules and forms. 

Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed 
by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company's management, including its 
principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. 

Management  recognizes  that  any  controls  and  procedures,  no  matter  how  well  designed  and  operated,  can  provide  only  reasonable  assurance  of 
achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. 
There are inherent limitations to the effectiveness of any system of disclosure controls and procedures. These limitations include the possibility of human 
error,  the  circumvention  or  overriding  of  the  controls  and  procedures  and  reasonable  resource  constraints.  In  addition,  because  we  have  designed  our 
system of controls based on certain assumptions, which we believe are reasonable, about the likelihood of future events, our system of controls may not 
achieve its desired purpose under all possible future conditions. Accordingly, our disclosure controls and procedures provide reasonable assurance, but not 
absolute assurance, of achieving their objectives.

Management's Annual Report on Internal Control over Financial Reporting 

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 
15d-15(f) under the Exchange Act) for the Company. Our internal control over financial reporting is designed to provide reasonable assurances regarding 
the reliability of financial reporting and the preparation of our 

100

 
consolidated financial statements in accordance with U.S. generally accepted accounting principles, or GAAP, and includes those policies and procedures 
that:

•

•

•

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

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

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

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements.  Also,  projections  of  any 
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree 
or compliance with the policies or procedures may deteriorate.

Our  management,  with  the  participation  of  its  Chief  Executive  Officer  and  Chief  Financial  Officer,  assessed  our  internal  control  over  financial 
reporting  as  of  December  31,  2021.  Management  based  its  assessment  on  criteria  established  in  Internal  Control—Integrated  Framework  issued  by  the 
Committee of Sponsoring Organizations of the Treadway Commission and concluded that our internal control over financial reporting was effective at the 
reasonable assurance level as of December 31, 2021.

This  Annual  Report  on  Form  10-K  does  not  include  an  attestation  report  of  our  independent  registered  public  accounting  firm  due  to  a  transition 

period established by rules of the SEC for “emerging growth companies”.

Remediation of Previously Reported Material Weakness

During the preparation of our consolidated financial statements as of and for the year ended December 31, 2020, we identified  material weaknesses in 

our internal control over financial reporting. The material weaknesses we identified were as follows:

•

•

•

•

we  did  not  design  or  maintain  an  effective  control  environment  commensurate  with  our  financial  reporting  requirements  due  to  lack  of  a 
sufficient number of accounting professionals with the appropriate level of experience and training;

we  did  not  design  and  maintain  formal  accounting  policies,  procedures  and  controls  to  achieve  complete,  accurate  and  timely  financial 
accounting, reporting and disclosures, and monitoring controls maintained at the corporate level were not at a sufficient level of precision to 
provide the appropriate level of oversight of activities related to our internal control over financial reporting;

we  did  not  design  and  maintain  effective  controls  over  segregation  of  duties  with  respect  to  the  preparation  and  review  of  account 
reconciliations as well as creating and posting manual journal entries; and 

we did not design and maintain formal accounting policies, processes and controls to analyze, account for and disclose complex transactions. 

We took a number of actions in 2021 to improve our internal control over financial reporting to remediate these material weaknesses. The remediation 

efforts and progress summarized below are intended to address and remediate the identified material weaknesses:

•

•

•

In the first quarter of 2021, we engaged a permanent Vice President, Corporate Controller, and a Senior Manager of Finance, together with 
third-party consultants, to improve and oversee all aspects of accounting operations, financial reporting, and Sarbanes-Oxley Act of 2002, as 
amended, compliance; 

We  also  successfully  implemented  a  new  Enterprise  Resource  Planning  (ERP)  system,  Microsoft  365  Business  Central,  in  January  2021, 
replacing QuickBooks and providing efficiency and financial controls. We provided appropriate training to all key accounting personnel who 
are responsible for posting and reviewing journal entries; and 

In the first quarter of 2021, we reevaluated our existing internal controls and, in the second quarter, we implemented additional controls to 
enhance our internal control environment. Since the third quarter of 2021, we have been performing internal control testing to ensure these 
controls are operating effectively as designed and implemented. 

101

 
For  the  year  ended  December  31,  2021,  we  completed  our  testing  of  the  design  and  operating  effectiveness  of  the  implemented  controls  and 
determined  they  were  effective.  As  a  result,  we  have  concluded  the  material  weaknesses  identified  in  fiscal  year  2020  have  been  remediated  as  of 
December 31, 2021. 

We  cannot  assure  you  that  material  weaknesses  or  significant  deficiencies  will  not  occur  in  the  future  or  that  we  will  be  able  to  remediate  such 
weaknesses or deficiencies in a timely manner, which could impair our ability to accurately and timely report our financial position, results of operations or 
cash flows. For additional information, see the related risks in the section titled "Risk Factors" of this Annual Report on Form 10-K.

Changes in Internal Control over Financial Reporting

Other than as stated above, no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange 
Act) occurred during the year ended December 31, 2021 that has materially affected, or is reasonably likely to materially affect, our internal control over 
financial reporting. As a result of the COVID-19 pandemic, since March 2020, we have requested that our employees work remotely, as appropriate. We 
have not identified any material changes in our internal control over financial reporting as a result of these changes to the working environment. We are 
continually monitoring and assessing the COVID-19 situation to determine any potential impacts on the design and operating effectiveness of our internal 
controls over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors
Adicet Bio, Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Adicet Bio, Inc. and subsidiaries (the Company) as of December 31, 2021 and 2020, the 
related consolidated statements of operations and comprehensive loss, redeemable convertible preferred stock and stockholders’ equity (deficit), and cash 
flows for the years then ended, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial 
statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations 
and its cash flows for the years then ended, in conformity with U.S. generally accepted accounting principles. 

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these 
consolidated 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 consolidated 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 consolidated 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 consolidated 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 consolidated financial statements. We believe that our audits provide a reasonable basis 
for our opinion.

/s/ KPMG LLP

We have served as the Company’s auditor since 2020.

Notes to Consolidated Financial Statements

1. Organization and Nature of the Business

Adicet Bio, Inc. (formerly resTORbio, Inc. (resTORbio)), together with its subsidiaries, (the Company) is a clinical stage biotechnology company 
discovering and developing allogeneic gamma delta T cell therapies for cancer. The Company is advancing a pipeline of off-the-shelf gamma delta T cells, 
engineered with chimeric antigen receptors (CARs) and T cell receptor-like antibodies to enhance selective tumor targeting, facilitate innate and adaptive 
anti-tumor immune response, and improve persistence for durable activity in patients. The Company's approach to activate, engineer, and manufacture 
allogeneic gamma delta T cell product candidates derived from the peripheral blood cells of unrelated donors allows it to generate new product candidates 
in a rapid and cost efficient manner. 

The Company was incorporated in November 2014 in Delaware. The principal executive offices are located in Boston, Massachusetts. The Company 

also has another office in Menlo Park, California.

Adicet Bio, Inc. (when referred to prior to the Merger (as defined below), (Former Adicet)) was incorporated in November 2014 in Delaware and was 

headquartered in Menlo Park, CA. Adicet Bio Israel Ltd. (formerly Applied Immune Technologies Ltd.) (Adicet Israel) is a wholly owned subsidiary of 
Former Adicet and is located in Haifa, Israel. Adicet Israel was founded in 2006. During 2019, Former Adicet consolidated its operations, including 
research and development activities, in the United States and as a result substantially reduced its operations in Israel.

Merger with resTORbio

Prior to September 15, 2020, the Company was a clinical-stage biopharmaceutical company known as resTORbio that had historically focused on 
developing innovative medicines that target the biology of aging, to prevent or treat age-related diseases with the potential to extend healthy lifespans. On 
April 28, 2020, resTORbio entered into a definitive Merger Agreement with Former Adicet. Under the terms of the Merger Agreement, Former Adicet 
agreed to merge with a wholly owned subsidiary of resTORbio in an all-stock transaction with Former Adicet surviving as a wholly owned subsidiary of 
resTORbio and changing its name to “Adicet Therapeutics, Inc.” (such transactions, the Merger). Under the exchange ratio formula in the Merger 
Agreement, immediately following the Effective Time of the Merger, the securityholders of Former Adicet as of immediately prior to the Effective Time of 
the Merger owned approximately 75% of the outstanding shares of the Company’s common stock on a fully-diluted basis and securityholders of resTORbio 
as of immediately prior to the Effective Time of the Merger owned approximately 25% of the outstanding shares of the Company’s common stock on a 
fully-diluted basis (in each case excluding equity incentives available for grant).

The Company concluded that the transaction represented a business combination pursuant to Financial Accounting Standards Board (FASB) 

Accounting Standards Codification (ASC) Topic 805, Business Combinations. Further, Former Adicet was determined to be the accounting acquirer based 
upon the terms of the Merger and other factors including: (i) Former Adicet’s securityholders own approximately 75% of the voting rights of the combined 
company (on a fully-diluted basis excluding equity incentives available for grant); (ii) Former Adicet designated a majority (five of seven) of the initial 
members of the Board of Directors of the combined company; and (iii) the terms of the exchange of equity interests based on the exchange ratio at the 
announcement of the Merger factored in an implied premium to resTORbio’s stockholders. The composition of senior management of the combined 
company was determined to be a neutral factor in the accounting acquirer determination, as the combined company will leverage the expertise of the senior 
management of both companies. Accordingly, the reported operating results prior to the business combination are those of Former Adicet.

On September 15, 2020, the Company completed the Merger pursuant to the Merger Agreement (the Effective Time). In connection with the Merger, 

and immediately prior to the Effective Time, resTORbio effected a reverse stock split of its common stock at a ratio of 1-for-7 (the Reverse Stock Split). 
Also, in connection with the Merger, the Company changed its name from “resTORbio, Inc.” to “Adicet Bio, Inc.” (the Name Change), Former Adicet 
changed its name from “Adicet Bio, Inc.” to “Adicet Therapeutics, Inc.” and the business conducted by the Company became primarily the business, which 
was previously conducted by Former Adicet, which is a biotechnology company discovering and developing allogeneic gamma delta T cell therapies for 
cancer and other diseases.

At the Effective Time, each outstanding share of Former Adicet capital stock was converted into the right to receive 0.1240 (the Exchange Ratio) 
shares of Company’s common stock, as set forth in the Merger Agreement. The Exchange Ratio was determined based on the total number of outstanding 
shares of Company’s common stock and Former Adicet capital stock, each on a fully diluted basis, and the respective valuations of Former Adicet and 
resTORbio at the time of execution of the Merger Agreement. In connection with the Merger, the Company also assumed certain outstanding Former 
Adicet warrants and Former Adicet stock options under Former Adicet’s 2015 Stock Incentive Plan (the 2015 Adicet Stock Incentive Plan) and Former 
Adicet’s 2014 Share Option Plan (the 2014 Share Option Plan and, together with the 2015 Adicet Stock Incentive Plan, the Former Adicet Plans), with such 
stock options and warrants henceforth representing the right to purchase a number of shares of Company’s common stock equal to the Exchange Ratio 
multiplied by the number of shares of Former Adicet’s 

F-7

Notes to Consolidated Financial Statements

capital stock previously represented by such stock options and warrants, as applicable, with a proportionate adjustment in exercise price.

Immediately following the Effective Time, there were approximately 19,589,828 shares of the Company’s common stock outstanding (post Reverse 

Stock Split), with the former equity holders of Former Adicet holding approximately 75% of the outstanding shares of Company’s common stock on a 
fully-diluted basis and the former equity holders of resTORbio holding approximately 25% of the outstanding shares of Company’s common stock on a 
fully-diluted basis (in each case excluding equity incentives available for grant).

Please refer to Note 3 “Business Combinations” for further discussions of the Merger.

Liquidity

The Company has incurred significant net operating losses and negative cash flows from operations since inception and had an accumulated deficit of 

$168.3 million as of December 31, 2021. The Company has historically financed its operations primarily through a collaboration and licensing 
arrangement, the private placement of equity securities and debt, and cash received in the Merger. To date, none of the Company’s product candidates have 
been approved for sale and therefore the Company has not generated any revenue from product sales. Management expects operating losses and negative 
cash flows to continue for the foreseeable future, until such time, if ever, that it can generate significant sales of its product candidates currently in 
development.

In February 2021, the Company completed an underwritten public offering of 10,575,513 shares of its common stock at a public offering price of 
$13.00 per share. The Company received net proceeds from the offering, after deducting underwriting discounts and commissions and offering expenses of 
approximately $128.8 million. In connection with the offering, the Company also entered into a stock purchase agreement with certain existing investors to 
purchase 1,153,840 shares of its common stock for $15.0 million at a price per share equal to the public offering price, with an initial closing for certain 
investors held simultaneously with the closing of the offering and a subsequent closing for certain additional investors.

In December 2021, the Company closed an underwritten public offering, or the December 2021 Follow-On Offering, of 7,187,500 shares of its 
common stock at a public offering price of $14.00 per share. The Company received net proceeds from the offering, after deducting underwriting discounts 
and commissions and offering expenses of approximately $94.2 million.

The Company expects that its cash and cash equivalents balances as of December 31, 2021, including the gross proceeds it received in February 2021 
and December 2021 from its underwritten public offerings and the proceeds received from a stock purchase agreement with certain existing investors, will 
be sufficient to fund its forecasted operating expenses, capital expenditure requirements for at least the next twelve months from the issuance of these 
annual consolidated financial statements.

All of the Company’s revenue to date is generated from the Regeneron Agreement, which is a collaboration and license agreement with Regeneron. 

The Company does not expect to generate any significant product revenue until it obtains regulatory approval of and commercialize any of the Company’s 
product candidates or enter into additional collaborative agreements with third parties, and it does not know when, or if, either will occur. The Company 
expects to continue to incur significant losses for the foreseeable future, and it expects the losses to increase as the Company continues the development of, 
and seek regulatory approvals for, its product candidates and begin to commercialize any approved products. The Company is subject to all of the risks 
typically related to the development of new product candidates, including, but not limited to, raising additional capital, development by its competitors of 
new technological innovations, risk of failure in preclinical and clinical studies, safety and efficacy of its product candidates in clinical trials, the risk of 
relying on external parties such as contract research organizations (CROs) and contract manufacturing organizations (CMOs), the regulatory approval 
process, market acceptance of the Company’s products once approved, lack of marketing and sales history, dependence on key personnel and protection of 
proprietary technology and it may encounter unforeseen expenses, difficulties, complications, delays, and other unknown factors that may adversely affect 
its business.

Until such time as the Company can generate significant revenue from product sales, if ever, the Company expects to finance its operations through 
the sale of equity, debt financings, collaborative or other arrangements with corporate or other sources of financing. Adequate funding may not be available 
to the Company on acceptable terms or at all. The Company’s failure to raise capital as and when needed could have a negative impact on its financial 
condition and the Company’s ability to pursue its business strategies. Although the Company continues to pursue these plans, there is no assurance that the 
Company will be successful in obtaining sufficient funding on terms acceptable to the Company to fund continuing operations, if at all.

2. Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements and related disclosures have been prepared in conformity with accounting principles generally accepted in the 

United States of America (United States GAAP or GAAP).

Principles of Consolidation

The  consolidated  financial  statements  include  the  accounts  of  the  Company  and  its  wholly  owned  subsidiaries.  All  intercompany  accounts  and 

transactions have been eliminated in consolidation. The United States dollar is the functional and reporting currency of the Company and its subsidiaries.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect 
the  reported  amounts  of  assets  and  liabilities  and  disclosures  of  contingent  liabilities  at  the  date  of  the  consolidated  financial  statements  as  well  as  the 
reported amounts of revenues and expenses during the reporting period. Such estimates include the valuation of the intangible assets acquired in business 
combinations, redeemable convertible preferred stock warrant liability, redeemable convertible preferred stock tranche liability, the Technion Research and 
Development Foundation liability (TRDF Liability), contingent consideration liability for contingent value right (CVR), deferred tax assets, useful lives of 
property  and  equipment,  accruals  for  research  and  development  activities,  revenue  recognition  and  stock-based  compensation  and  the  Company’s 
incremental borrowing rate. Actual results could differ from those estimates.

Contingent Consideration Liability (CVR)

The estimated fair value of the CVR, initially measured and recorded on the acquisition date, is considered to be a Level 3 instrument. The contingent 
consideration  liability  is  recorded  at  fair  value  at  the  end  of  each  reporting  period  with  changes  in  estimated  fair  values  recorded  in  research  and 
development expenses in the consolidated statements of operations and comprehensive loss. During the second quarter of 2021, the Company performed a 
re-measurement of the fair value of the CVR liability and adjusted the liability to zero. This resulted in a $1.0 million gain in research and development 
expense in the statements of operations and comprehensive loss for the year ended December 31, 2021. 

Goodwill

Goodwill  represents  the  excess  of  the  purchase  price  over  the  fair  value  of  net  tangible  and  identified  intangible  assets  acquired  in  a  business 
combination. Goodwill is not amortized but is evaluated at least annually for impairment or when a change in facts and circumstances indicate that the fair 
value of the goodwill may be below the carrying value.

Goodwill  is  tested  for  impairment  at  the  reporting  unit  level  annually  in  the  fourth  quarter,  or  more  frequently  when  events  or  changes  in 
circumstances indicate that the asset might be impaired. Examples of such events or circumstances include, but are not limited to, a significant adverse 
change in legal or business climate, an adverse regulatory action or unanticipated competition. The Company has determined that it operates in a single 
operating segment and has a single reporting unit.

Prior  to  performing  the  impairment  test,  the  Company  assesses  qualitative  factors  to  determine  whether  the  existence  of  events  or  circumstances 
would indicate that it is more likely than not that the fair value of the reporting unit was less than the carrying amount. If after assessing the totality of 
events or circumstances, the Company were to determine that it is more likely than not that the fair value of the reporting unit is less than the carrying 
amount, then the Company would perform a quantitative impairment test.

The quantitative impairment test involves comparing the fair value of the reporting unit to the carrying value. If the fair value of the reporting unit 
exceeds the carrying value of the net assets, goodwill is not impaired, and no further testing is required. If the fair value of the reporting unit is less than the 
carrying value, the Company measures the amount of impairment loss, if any, as the excess of the carrying value over the fair value of the reporting unit. 
The  Company  performed  an  annual  test  for  goodwill  impairment  in  the  fourth  quarter  of  the  fiscal  year  ended  December  31,  2021  and  determined  that 
goodwill was not impaired.

Intangible Assets

In  connection  with  the  Merger,  the  Company  acquired  certain  IPR&D  assets,  which  were  classified  as  indefinite-lived  intangible  assets.  Acquired 
IPR&D represents the fair value assigned to research and development assets that the Company acquires and have not been completed at the acquisition 
date. The fair value of IPR&D acquired in a business combination is recorded on the Company’s consolidated balance sheets at the acquisition-date fair 
value and is determined by estimating the costs to develop the technology into commercially viable products, estimating the resulting revenue from the 
products, and discounting the projected net cash flows to present value. IPR&D is not amortized, but rather is reviewed for impairment on an annual basis 
or  more  frequently  if  indicators  of  impairment  are  present,  until  the  project  is  completed,  abandoned,  or  transferred  to  a  third  party.  The  Company 
performed a review for impairment of IPR&D during the second quarter of the year ended December 31, 2021 and recognized an impairment charge of 
$1.2 million, which was recorded as research and development expenses in the consolidated statement of operations and comprehensive loss.  

Segments

The  Company  operates  and  manages  its  business  as  one  reportable  and  operating  segment,  which  is  the  business  of  research  and  development  of 
allogeneic immunotherapies for cancer and other diseases. The Company’s Chief Executive Officer, who is the chief operating decision maker, reviews 
financial information on an aggregate basis for purposes of allocating resources and evaluating financial performance.

Concentration of Credit Risk

Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash and cash equivalents, and 
marketable debt securities. The Company’s cash and cash equivalents are held at two financial institutions in the United States and one financial institution 
in Israel and such amounts may, at times, exceed insured limits. The Company invests its cash equivalents and marketable debt securities in money market 
funds, United States government securities, commercial paper, corporate bonds, and asset-backed securities. The Company limits its credit risk associated 
with cash equivalents and marketable debt securities by placing them with banks and institutions it believes are highly creditworthy and in highly rated 
investments. The Company has not experienced any losses on its deposits of cash and cash equivalents and marketable debt securities to date.

The Company has one customer, Regeneron, which represents 100% of the Company’s total revenue during the years ended December 31, 2021 and 

2020 and outstanding accounts receivable as of December 31, 2021 (see Note 10).

Risks and Uncertainties

The  Company  is  subject  to  risks  and  uncertainties  common  to  early-stage  companies  in  the  biotechnology  industry,  including,  but  not  limited  to, 
development  by  competitors  of  new  technological  innovations,  protection  of  proprietary  technology,  dependence  on  key  personnel,  compliance  with 
government  regulations  and  the  need  to  obtain  additional  financing  to  fund  operations.  Product  candidates  currently  under  development  will  require 
significant  additional  research  and  development  efforts,  including  extensive  preclinical  studies,  clinical  trials,  and  regulatory  approval,  prior  to 
commercialization.  These  efforts  require  significant  amounts  of  additional  capital,  adequate  personnel  infrastructure  and  extensive  compliance  and 
reporting.

The Company’s product candidates are still in development and, to date, none of the Company’s product candidates have been approved for sale and, 

therefore, the Company has not generated any revenue from product sales.

There can be no assurance that the Company’s research and development will be successfully completed, that adequate protection for the Company’s 
intellectual  property  will  be  obtained  or  maintained,  that  any  products  developed  will  obtain  necessary  government  regulatory  approval  or  that  any 
approved  products  will  be  commercially  viable.  Even  if  the  Company’s  product  development  efforts  are  successful,  it  is  uncertain  when,  if  ever,  the 
Company will generate revenue from product sales. The Company operates in an environment of rapid change in technology and substantial competition 
from other pharmaceutical and biotechnology companies.

The current  COVID-19  (coronavirus)  pandemic,  which  is  impacting  worldwide  economic  activity,  poses  risk  that  the  Company  or  its  employees, 
contractors, suppliers, and other partners may be prevented from conducting business activities for an indefinite period of time, including due to shutdowns 
that may be requested or mandated by governmental authorities. The extent to which the coronavirus impacts the Company’s operations will depend on 
future developments, which are highly uncertain and cannot be predicted with confidence, including the duration of the outbreak, new information that will 
emerge concerning the severity of the coronavirus and the actions to contain the coronavirus or treat its impact, among others. COVID-19 may impact the 
timing of regulatory approval of the INDs for clinical trials, the enrollment of any clinical trials that are 

F-10

 
Adicet Bio, Inc.
Notes to Consolidated Financial Statements

approved,  the  availability  of  clinical  trial  materials  and  regulatory  approval  and  commercialization  of  our  products.  COVID-19  may  also  impact  the 
Company’s ability to access capital, which could negatively impact short-term and long-term liquidity.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with maturities of three months or less from the purchase date to be cash equivalents. 
As of December 31, 2021 and 2020, cash and cash equivalents consist of cash deposited with banks and investments in money market funds with maturities 
of three months or less from the date of purchase.

Marketable Debt Securities

Marketable  debt  securities  are  investments  in  marketable  debt  securities  with  maturities  greater  than  three  months  at  the  time  of  purchase.  The 
Company determines the appropriate classification of its investments in marketable debt securities at the time of purchase and reevaluates such designation 
at  each  balance  sheet  date.  The  Company  has  classified  and  accounted  for  its  marketable  debt  securities  as  available-for-sale.  The  Company  classifies 
highly liquid securities with maturities beyond 12 months as long-term marketable debt securities in the consolidated balance sheet. These securities are 
carried  at  fair  value  as  determined  based  upon  quoted  market  prices  or  pricing  models  for  similar  securities.  Unrealized  gains  and  losses,  if  any,  are 
excluded  from  earnings  and  are  reported  as  a  component  of  accumulated  other  comprehensive  income  (loss).  The  amortized  cost  of  debt  securities  is 
adjusted  for  amortization  of  premiums  and  accretion  of  discounts  to  maturity,  which  is  included  in  interest  income  on  the  consolidated  statements  of 
operations and comprehensive loss. Realized gains and losses, if any, on available-for-sale securities are included in other income (expense), net. The cost 
of securities sold is based on the specific identification method. Interest and dividends on securities classified as available-for-sale are included in interest 
income. The Company did not have any outstanding marketable debt securities as of December 31, 2021 and did not identify any of its marketable debt 
securities as other-than-temporarily impaired as of December 31, 2020.

Restricted Cash

Restricted cash is comprised of cash that is restricted as to withdrawal or use under the terms of certain contractual agreements. Restricted cash for 

years ended December 31, 2021 and 2020 consists of collateral for letters of credit issued in connection with real estate leases (see Note 12).

Fair Value of Financial Instruments

The carrying amounts of certain financial instruments of the Company, including cash equivalents, restricted cash, accounts payable and accrued and 
other  current  liabilities  approximate  fair  value  due  to  their  relatively  short  maturities.  The  Company’s  marketable  debt  securities  and  CVR  liability  are 
carried at fair value (see Notes 4 and 5).

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 years. Leasehold improvements are amortized using the straight-line method over the shorter of 
the assets’ estimated useful lives or the remaining term of the lease. Maintenance and repairs are charged to operations as incurred. When assets are retired 
or otherwise disposed of, the cost and accumulated depreciation are removed from the consolidated balance sheet and any resulting gain or loss is reflected 
in the consolidated statements of operations and comprehensive loss in the period realized.

Impairment of Long-Lived Assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or 
asset group may not be recoverable. Recoverability is measured by comparison of the carrying amount of the asset or asset group to the future net cash 
flows which the asset or asset group is expected to generate. If such asset or asset group is considered to be impaired, the impairment to be recognized is 
measured by the amount by which the carrying amount of the asset or asset group exceeds the fair value of the asset or asset group. There has been no such 
impairment of long-lived assets during the years ended December 31, 2021 and 2020.

Revenue Recognition

Under ASC 606, Revenue from Contracts with Customers (ASC 606), the Company recognizes revenue when its customer obtains control of promised 

goods or services, in an amount that reflects the consideration which the Company expects to receive 

F-11

 
Adicet Bio, Inc.
Notes to Consolidated Financial Statements

in exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within the scope of ASC 606, 
the Company performs the following five steps as prescribed by ASC 606:

(i)

identify the contract(s) with a customer;

(ii)

identify the performance obligations in the contract;

(iii) determine the transaction price;

(iv) allocate the transaction price to the performance obligations in the contract; and

(v)

recognize revenue when (or as) the Company satisfies a performance obligation.

A contract with a customer exists when (i) the Company enters into a legally enforceable contract with a customer that defines each party’s rights 
regarding the products or services to be transferred and identifies the payment terms related to these products or services, (ii) the contract has commercial 
substance and (iii) the Company determines that collection of substantially all consideration for products or services that are transferred is probable based 
on the customer’s intent and ability to pay the promised consideration.

At contract inception, once the contract is determined to be within the scope of ASC 606, the Company identifies the goods or services promised and 
determines the performance obligations by assessing whether each promised good or service is distinct. Goods or services that are not distinct are bundled 
with other goods or services in the contract until a bundle of goods or services that is distinct is created. The Company then recognizes as revenue the 
amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

All of the Company’s revenues are derived through a license and collaboration agreement (see Note 10).

For revenue recognition purposes, the Company determines the term of its license or collaboration agreements by evaluating the period during which 
present  and  enforceable  rights  and  obligations  exist.  This  determination  is  impacted  by  the  existence  of  substantive  termination  penalties,  among  other 
factors.

The Company recognizes revenue under the Company’s license or collaboration agreements that are within the scope of ASC 606. These agreements 
include promises related to licenses to intellectual property and research and development services. If the license to the Company’s intellectual property is 
determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenue from non-refundable, up-
front fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that 
are bundled with other promises, the Company utilizes judgement to assess the nature of the combined performance obligation to determine whether the 
combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of 
recognizing revenue from non-refundable, up-front fees. Accordingly, the transaction price is generally comprised of a fixed fee due at contract inception 
and at specified future dates, variable consideration in the form of milestone payments due upon the achievement of specified events and tiered royalties 
earned when customers recognize net sales of licensed products. The Company measures the transaction price based on the amount of consideration to 
which  it  expects  to  be  entitled  in  exchange  for  transferring  the  promised  goods  and/or  services  to  the  customer.  The  Company  utilizes  the  “most  likely 
amount”  method  to  estimate  the  amount  of  variable  consideration  to  which  it  will  be  entitled  for  the  contract.  Amounts  of  variable  consideration  are 
included in the transaction price to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur 
when the uncertainty associated with the variable consideration is subsequently resolved. At the inception of each arrangement that includes development 
and regulatory milestone payments, the Company evaluates whether the associated event is considered most likely to be achieved and estimates the amount 
to be included in the transaction price.

Payments or reimbursements for the Company’s research and development efforts where such efforts are considered part of or a single performance 

obligation are recognized over time using a measure of progress that best reflects the Company’s performance in satisfying the obligation.

Upfront payments are recorded as contract liabilities upon receipt or when due and may require deferral of revenue recognition to a future period until 
the  Company  performs  its  obligation  under  these  arrangements.  Amounts  payable  to  the  Company  are  recorded  as  accounts  receivable  when  the 
Company’s  right  to  consideration  is  unconditional.  The  Company  does  not  assess  whether  a  contract  has  a  significant  financing  component  if  the 
expectation  at  contract  inception  is  such  that  the  period  between  payment  by  the  customer  and  the  transfer  of  the  promised  goods  or  services  to  the 
customer will be one year or less.

F-12

 
Adicet Bio, Inc.
Notes to Consolidated Financial Statements

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

Research and Development Expenses

Research and development expenses include costs directly attributable to the conduct of research and development programs, including payroll and 
related expenses, costs for CMOs, costs for CROs, materials, supplies, depreciation on and maintenance of research equipment, consulting costs, and the 
allocated  portions  of  facility  costs,  such  as  rent,  utilities,  insurance,  repairs  and  maintenance,  depreciation,  information  technology  costs  and  general 
support services. All costs associated with research and development are expensed within the consolidated statements of operations and comprehensive loss 
as incurred.

Costs incurred in obtaining technology licenses are charged to research and development expense as acquired in-process research and development if 

the technology licensed has not reached technological feasibility and has no alternative future use.

Accrued CRO, CMO, and Research and Development Expenses

The Company has entered into various agreements with CMOs and CROs. The Company’s research and development accruals are estimated based on 
the level of services performed, progress of the studies, including the phase or completion of events, and contracted costs. The estimated costs of research 
and development provided, but not yet invoiced are included in accrued and other current liabilities on the consolidated balance sheets. If the actual timing 
of the performance of services or the level of effort varies from the original estimates, the Company will adjust the accrual accordingly. Payments made to 
CMOs and CROs under these arrangements in advance of the performance of the related services are recorded as prepaid expenses and other current assets 
on the consolidated balance sheets until the services are rendered. Through December 31, 2021 there had been no material adjustments to the Company’s 
prior period estimates of accrued research and development expenses.

Leases

 Effective January 1, 2020, the Company adopted ASU No. 2016-02, Leases (Topic 842) (ASU 2016-02), using the modified retrospective approach 
through a cumulative-effect adjustment as of the adoption date, with prior periods unchanged and presented in accordance with the guidance in Topic 840, 
Leases (Topic 840).

Consistent with ASU 2016-02, the Company determines if an arrangement is a lease, or contains a lease, at inception. Leases with a term greater than 
12  months  are  recognized  on  the  balance  sheet  as  Right-of-Use  (ROU)  assets  and  current  and  long-term  operating  lease  liabilities,  as  applicable.  The 
Company has elected not to recognize on the balance sheet leases with terms of 12 months or less. The Company typically only includes an initial lease 
term in its assessment of a lease arrangement. Options to renew a lease are not included in the Company’s assessment unless there is reasonable certainty 
that  the  Company  will  renew.  The  Company  monitors  its  plan  to  renew  its  leases  no  less  than  on  a  quarterly  basis.  In  addition,  the  Company’s  lease 
agreements generally do not contain any residual value guarantees or restrictive covenants. 

In  accordance  with  ASU  2016-02,  the  ROU  assets  and  lease  liabilities  are  recognized  based  on  the  present  value  of  the  future  minimum  lease 
payments over the lease term. As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate (IBR), 
which is the estimated rate the Company would be required to pay for a fully collateralized borrowing equal to the total lease payments over the term of the 
lease, to determine the present value of future minimum lease payments. Lease expense for minimum lease payments is recognized on a straight-line basis 
over the lease term. For lease agreements entered into or reassessed after the adoption of ASU 2016-02, the Company does not combine lease and non-lease 
components. Variable lease payments are expenses as incurred.

Assumptions made by the Company at the commencement date are re-evaluated upon occurrence of certain events, including a lease modification. A 
lease modification results in a separate contract when the modification grants the lessee an additional right of use not included in the original lease and 
when  lease  payments  increase  commensurate  with  the  standalone  price  for  the  additional  right  of  use.  When  a  lease  modification  results  in  a  separate 
contract, it is accounted for in the same manner as a new lease.

Fair Value of Common Stock

Prior to the Merger the fair value of the Company’s common stock was determined by its Board of Directors with input from management and third-
party valuation specialists. The Company’s approach to estimate the fair value of the Company’s common stock is consistent with the methods outlined in 
the American Institute of Certified Public Accountants Practice Aid, Valuation 

F-13

 
Adicet Bio, Inc.
Notes to Consolidated Financial Statements

of Privately-Held-Company Equity Securities Issued as Compensation. Determining the best estimated fair value of the Company’s common stock requires 
significant  judgement  and  management  considers  several  factors,  including  the  Company’s  stage  of  development,  equity  market  conditions  affecting 
comparable  public  companies,  significant  milestones  and  progress  of  research  and  development  efforts.  Subsequent  to  the  Merger,  the  fair  value  of  the 
Company’s common stock is determined based on its closing market price.

Stock-Based Compensation

The Company accounts for stock-based compensation arrangements with employees and non-employees using a fair value method which requires the 
recognition of compensation expense for costs related to all stock-based payments including stock options. The fair value method requires the Company to 
estimate the fair value of stock-based payment awards on the date of grant using an option-pricing model. The Company uses the Black-Scholes option-
pricing model to estimate the fair value of options granted that are expensed on a straight-line basis over the requisite service period, which is generally the 
vesting period. The Company accounts for forfeitures as they occur. Option valuation models, including the Black-Scholes option-pricing model, require 
the input of several assumptions. Changes in the assumptions used can materially affect the grant-date fair value of an award. These assumptions include 
the risk-free rate of interest, expected dividend yield, expected volatility and the expected life of the award. For awards that have a performance condition, 
the  Company  recognizes  compensation  expense  based  on  its  assessment  of  the  probability  that  the  performance  condition  will  be  achieved,  using  an 
accelerated attribution model, over the explicit or implicit service period.

Income Taxes

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

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

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

Comprehensive Income (Loss)

Comprehensive income (loss) is defined as a change in equity of a business enterprise during a period, resulting from transactions from non-owner 
sources.  The  other  comprehensive  loss  disclosed  in  the  Company’s  consolidated  statements  of  operations  and  comprehensive  loss  for  the  years  ended 
December 31, 2021 and 2020 consists of changes in unrealized gains and losses on marketable debt securities.

Net Loss per Share Attributable to Common Stockholders

Basic net  loss  per  common  share  is  calculated  by  dividing  the  net  loss  attributable  to  common  stockholders  by  the  weighted-average  number  of 
common stock outstanding during the period, without consideration of potentially dilutive securities. Diluted net loss per share is computed by dividing the 
net  loss  attributable  to  common  stockholders  by  the  weighted-average  number  of  common  stock  and  potentially  dilutive  securities  outstanding  for  the 
period.  The  Company’s  potentially  dilutive  shares,  which  include  outstanding  stock  options,  Employee  Stock  Purchase  Plan  awards,  unvested  restricted 
stock units (RSUs), and shares issuable upon conversion of the Convertible Notes, are considered to be common stock equivalents and are only included in 
the  calculation  of  diluted  net  loss  per  share  when  their  effect  is  dilutive.  Basic  and  diluted  net  loss  per  share  attributable  to  common  stockholders  is 
presented in conformity with the two-class method required for participating securities. The two-class method determines net income (loss) per share for 
each class of common and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The 
two-class method requires income (loss) available to common 

F-14

 
Adicet Bio, Inc.
Notes to Consolidated Financial Statements

stockholders  for  the  period  to  be  allocated  between  common  and  participating  securities  based  upon  their  respective  rights  to  share  in  undistributed 
earnings as if all income (loss) for the period had been distributed. The Company’s participating securities do not have a contractual obligation to share in 
the  Company’s  losses.  As  such,  the  net  loss  is  attributed  entirely  to  common  stockholders.  Since  the  Company  has  reported  a  net  loss  for  all  periods 
presented, diluted net loss per common share is the same as basic net loss per common share for those periods.

Subsequent Events Considerations 

The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the consolidated financial statements 
to  provide  additional  evidence  for  certain  estimates  or  to  identify  matters  that  require  additional  disclosure.  Subsequent  events  have  been  evaluated  as 
required.  The  Company  has  evaluated  all  subsequent  events  and  determined  that  there  are  no  material  recognized  or  unrecognized  subsequent  events 
requiring disclosure, other than as disclosed in these notes to the consolidated financial statements.  See Note 21 for further information.

Recent Accounting Pronouncements

From  time  to  time,  new  accounting  pronouncements  are  issued  by  the  FASB  under  its  ASC  or  other  standard  setting  bodies  and  adopted  by  the 

Company as of the specified effective date, unless otherwise discussed below.

Recently Adopted Accounting Pronouncements

In  August  2018,  the  FASB  issued  ASU  No.  2018-15,  Intangibles–Goodwill  and  Other—Internal-Use  Software  (Subtopic  350-40):  Customer’s 
Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (ASU 2018-15). The amendments in ASU 
2018-15 align 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  (and  hosting  arrangements  that  include  an  internal-use  software 
license). Accordingly, the update requires entities in a hosting arrangement that is a service contract to follow the guidance in ASC 350-40, Internal-Use 
Software (ASC 350-40) to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. Costs 
to  develop  or  obtain  internal-use  software  that  cannot  be  capitalized  under  ASC  350-40,  such  as  training  costs  and  certain  data  conversion  costs,  also 
cannot be capitalized for a hosting arrangement that is a service contract. Therefore, an entity in a hosting arrangement that is a service contract determines 
which  project  stage  an  implementation  activity  relates  to.  Costs  for  implementation  activities  in  the  application  development  stage  are  capitalized 
depending on the nature of the costs, while costs incurred during the preliminary project and post-implementation stages are expensed as the activities are 
performed. ASU 2018-15 also requires entities to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the 
term of the hosting arrangement. ASU 2018-15 was effective for public entities for annual periods beginning after December 15, 2019, including interim 
periods within those fiscal years. For nonpublic entities, ASU 2018-15 is effective for annual reporting periods beginning after December 15, 2020, and 
interim  periods  within  annual  periods  beginning  after  December  15,  2021.  Early  adoption  is  permitted,  including  adoption  in  any  interim  period.  The 
Company adopted ASU 2018-15 beginning January 1, 2021. The adoption of ASU 2018-15 resulted in an immaterial amount of assets recorded on the 
Company's balance sheet.

In November 2018, the FASB issued ASU No. 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction Between Topic 808 and 
Topic  606  (ASU  2018-18),  which  is  intended  to  clarify  the  circumstances  under  which  certain  transactions  in  collaborative  arrangements  should  be 
accounted  for  under  the  revenue  recognition  standard.  Certain  transactions  between  collaboration  arrangement  participants  should  be  accounted  for  as 
revenue under ASC Topic 606 when the collaborative arrangement participant is a customer in the context of a unit of account. For public business entities, 
this ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. For all other entities, this ASU is 
effective for fiscal years and interim periods within those years beginning after December 15, 2020. Early adoption is permitted.  The Company adopted 
ASU 2018-18 beginning January 1, 2021. The adoption of this standard did not have a material impact on the Company's financial statements and related 
disclosures.

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740)—Simplifying the Accounting for Income Taxes  (ASU  2019-12), 
which simplify various aspects related to the accounting for income taxes. This ASU removes exceptions to the general principles in Topic 740 related to 
the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities 
for outside basis differences. For public companies, this ASU is effective for interim and annual reporting periods beginning after December 15, 2020. For 
all other entities, the amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after 
December 15, 2022. Early adoption is permitted. The Company adopted ASU 2019-12 beginning January 1, 2021 on a prospective basis. The adoption of 
this standard did not have a material impact on the Company's financial statements and related disclosures

F-15

 
Adicet Bio, Inc.
Notes to Consolidated Financial Statements

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848) (ASU 2020-04). The amendments in ASU 2020-04 provide 
optional  expedients  and  exceptions  for  applying  generally  accepted  accounting  principles  to  contracts,  hedging  relationships,  and  other  transactions 
affected by reference rate reform if certain criteria are met. The amendments in ASU 2020-04 are effective for all entities as of March 12, 2020 through 
December  31,  2022.  An  entity  may  elect  to  apply  the  amendments  for  contract  modifications  by  Topic  or  Industry  Subtopic  as  of  any  date  from  the 
beginning an interim period that includes or is subsequent to March 12, 2020, or prospectively from the date that the financial statements are available to be 
issued.  Once  elected  for  a  Topic  or  an  Industry  Subtopic,  the  amendments  must  be  applied  prospectively  for  all  eligible  contract  modifications  for  that 
Topic or Industry Subtopic. The Company may elect to apply ASU 2020-04 as its contracts referenced in London Interbank Offered Rate (LIBOR) are 
impacted by reference rate reform. The Company adopted ASU 2020-04 beginning January 1, 2021. The adoption of this standard did not have a material 
impact on the Company's financial statements and related disclosures.

Accounting Pronouncements Not Yet Adopted

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial 
Instruments (ASU  2016-13),  which  requires  the  measurement  and  recognition  of  expected  credit  losses  for  financial  assets  held  at  amortized  cost.  This 
ASU replaces the existing incurred loss impairment model with an expected loss model. It also eliminates the concept of other-than-temporary impairment 
and requires credit losses related to available-for-sale debt securities to be recorded through an allowance for credit losses rather than as a reduction in the 
amortized cost basis of the securities. These changes will result in earlier recognition of credit losses. For public business entities that meet the definition of 
a  Securities  and  Exchange  Commission  (SEC)  filer,  excluding  entities  eligible  to  be  smaller  reporting  companies  as  defined  by  the  SEC,  adoption  is 
effective  for  fiscal  years  beginning  after  December  15,  2019,  including  interim  periods  within  those  fiscal  years.  For  SEC  filers  that  are  eligible  to  be 
smaller reporting companies and for all other entities, this ASU is effective for fiscal years beginning after December 15, 2022, and interim periods within 
those  fiscal  years.  Early  adoption  is  permitted.  The  Company  is  currently  evaluating  the  impact  the  adoption  of  this  ASU  will  have  on  its  consolidated 
financial statements and related disclosures.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment 
(ASU 2017-04). The new guidance simplifies the subsequent measurement of goodwill by removing the second step of the two-step impairment test. The 
amendment requires an entity to perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying 
amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. 
The new guidance for accelerated filing companies became effective for annual periods or any interim goodwill impairment tests in fiscal years beginning 
after December 15, 2019 and all other entities should adopt the amendments in this update for its annual or any interim goodwill impairment tests in fiscal 
years  beginning  after  December  15,  2022.  The  amendment  should  be  applied  on  a  prospective  basis.  Early  adoption  is  permitted  for  interim  or  annual 
goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact the adoption of this ASU will 
have on its consolidated financial statements and related disclosures. 

In July 2021, FASB issued ASU No. 2021-05, Lease (Topic 842), Lessors - Certain Leases with Variable Lease Payments (ASU 2021-05). ASU 2021-
05 amends the lease classification requirements for lessors when classifying and accounting for a lease with variable lease payments that do not depend on 
a reference rate index or a rate. The update provides criteria, that if met, the lease would be classified and accounted for as an operating lease. ASU 2021-
05 is effective for reporting periods beginning after December 15, 2021, with early adoption permitted. The Company is currently evaluating the impact of 
the adoption of this ASU on the Company's consolidated financial statements, but does not believe the adoption of this standard will have a material impact 
on the Company's consolidated financial statements. 

3. Business Combination

On September 15, 2020, Former Adicet completed its merger with resTORbio. Based on the Exchange Ratio of 0.1240, immediately following the 
Merger, resTORbio stockholders and holders of resTORbio restricted stock units and options to acquire resTORbio common stock owned approximately 
25.0% of the outstanding capital stock of the combined company on a fully diluted basis, and Former Adicet stockholders, holders of options or warrants to 
acquire Former Adicet capital stock owned approximately 75.0% of the outstanding capital stock of the combined company on a fully diluted basis.

resTORbio’s stockholders continued to own and hold their existing shares of the Company’s common stock (after giving effect to the 1-for-7 reverse 
stock split). Pursuant to the terms of the Merger, the vesting of all outstanding resTORbio stock options was accelerated in full as of immediately prior to 
the  Effective  Time.  All  out-of-the-money  resTORbio  stock  options  were  cancelled  for  no  consideration.  All  in-the-money  resTORbio  stock  options 
remained outstanding after the completion of the Merger in accordance with their terms. For accounting purposes, the Company assumed 81,370 in-the-
money resTORbio stock options after giving effect to reverse stock split. In addition, 91,309 unvested resTORbio restricted stock units outstanding 

F-16

Notes to Consolidated Financial Statements

and unsettled, after giving effect to reverse stock split, as of immediately prior to the Effective Time of the Merger, were accelerated in full and the holders 
of such restricted stock units received 54,553  shares  of  the  Company’s  common  stock  (after  reduction  by  the  number  of  shares  of  resTORbio  common 
stock  necessary  to  satisfy  applicable  tax  withholding  obligations  at  the  maximum  statutory  rate).  The  fair  value  of  these  modified  stock  options  and 
restricted stock units attributable to pre-combination services was recorded as a component of consideration transferred and the fair value of these modified 
stock  options  and  restricted  stock  units  attributable  to  post-combination  services  was  recognized  as  stock  compensation  expense  in  the  Company’s 
consolidated statements of operations and comprehensive loss.

At the closing of the Merger, all shares of Former Adicet common stock and Former Adicet redeemable convertible preferred stock then outstanding 

were converted to Former Adicet’s common stock under their original terms and were then exchanged for the Company’s common stock.

In connection with the Merger, the Company entered into a Contingent Value Rights Agreement (the CVR Agreement) with Computershare Inc. and 
Computershare Trust Company, N.A. as joint rights agent. Per the terms of the Merger, each holder of resTORbio common stock as of immediately prior to 
the completion of the Merger is entitled to one contractual contingent value right, subject to and in accordance with the terms and conditions of the CVR 
Agreement, for each share of resTORbio common stock held by such holder as of immediately prior to the Effective Time. The CVR holders were entitled 
to  receive  net  proceeds  from  the  commercialization,  if  any,  from  a  third-party  commercial  partner  of  RTB101,  resTORbio’s  small  molecule  product 
candidate that is a potent inhibitor of target of rapamycin complex 1 (TORC1), for a COVID-19 related indication.

The total purchase price was allocated to the tangible and intangible assets acquired and liabilities assumed of resTORbio based on their fair values as 
of the completion of the Merger, with the excess allocated to goodwill. The purchase price is calculated based on the fair value of resTORbio common 
stock that the resTORbio stockholders owned as of the closing date of the Merger because, with no active trading market for shares of Former Adicet, the 
fair value of the resTORbio’s common stock represented a more reliable measure of the fair value of consideration transferred in the Merger. The following 
summarizes the purchase price in the Merger (in thousands, except share and per share amounts):

amount is calculated as 5,207,695 shares (post-reverse stock split) of resTORbio common stock outstanding as of September 15, 2020.

The  fair  value  of  shares  of  the  combined  company  owned  by  resTORbio  stockholders  is  based  on  the  closing  price  of  resTORbio  common  stock  on 
September 14, 2020.

The fair value of resTORbio common stock was further adjusted to remove the estimated fair value of the CVR embedded within the closing price, as each 
holder of resTORbio stock received one contractual CVR immediately prior to the Merger.

(2) Each holder of resTORbio common stock as of immediately prior to the completion of the Merger was entitled to one CVR issued by resTORbio, subject to and in 
accordance  with  the  terms  and  conditions  of  the  CVR  Agreement,  for  each  share  of  resTORbio  common  stock  held  by  such  holder  as  of  immediately  prior  to  the 
Effective Time of the Merger.

(3) Based on the capitalization of resTORbio as of September 15, 2020, 91,309 outstanding unvested resTORbio restricted stock units were accelerated in connection with 

the Merger and holders of the restricted stock units were issued approximately 54,553 shares of resTORbio

common stock on a net settlement basis. Similarly, in connection with the Merger, vesting of outstanding resTORbio stock options was accelerated in full and the stock 
options that were not in the in-the-money on the close of the Merger were canceled, resulting in approximately 81,370 surviving stock options. The acquisition date 
fair value of these modified resTORbio restricted stock units and resTORbio stock options attributable to the pre-combination services is included in the estimated 
purchase price.

The Merger was accounted for as a business combination which requires that assets acquired, and liabilities assumed be recognized at their fair value 
as of the acquisition date. While the Company uses its best estimates and assumptions as part of the purchase price allocation process to value the assets 
acquired  and  liabilities  assumed  on  the  acquisition  date,  its  estimates  and  assumptions  are  subject  to  refinement.  Fair  value  estimates  are  based  on  a 
complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the 
estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact the Company’s results of 
operations.

The following summarizes the allocation of the purchase price to the net tangible and intangible assets acquired (in thousands):

The goodwill of $19.5  million  is  not  tax  deductible  and  represents  the  excess  of  the  consideration  paid  over  the  fair  value  of  assets  acquired  and 
liabilities assumed. Goodwill is mainly attributable to the enhanced value of the combined company, as reflected in the increase in market value of the 
resTORbio common shares following the announcement of the Merger with Former Adicet.

The  fair  value  of  acquired  IPR&D  is  related  to  the  research  and  development  of  RTB101  for  a  COVID-19  related  indication  and  was  conducted 
pursuant to resTORbio's license agreement with Novartis (see Note 11). The RTB101 compound IPR&D project was valued using an income approach, 
specifically a projected discounted cash flow method, adjusted for the probability of technical success (PTS). The projected discounted cash flow models 
used to estimate the Company’s IPR&D reflect significant assumptions regarding the estimates a market participant would make in order to evaluate a drug 
development asset, including the following:

•

•

•

•

Estimates  of  potential  cash  flows  to  be  generated  by  the  project  and  resulting  asset,  which  was  developed  utilizing  estimates  of  total  patient 
population, market penetration rates, demand risk adjustment factors, and product pricing; 

Estimates regarding the timing of and the expected costs of goods sold, research and development expenses, selling, general and administrative 
expenses to advance the clinical programs to commercialization, cash flow adjustments and partner profit split; 

The projected cash flows were then adjusted using PTS factors that were selected considering both the current state of clinical development and 
the nature of the proposed indication, (i.e., respiratory therapeutics); and 

Finally,  the  resulting  probability  adjusted  cash  flows  were  discounted  to  a  present  value  using  a  risk-adjusted  discount  rate,  developed 
considering the market risk present in the forecast and the size of the asset. 

This IPR&D intangible asset is not amortized, but rather is reviewed for impairment on an annual basis or more frequently if indicators of impairment 
are present, until the project is completed, abandoned, or transferred to a third party. Upon the review of impairment indicators of IPR&D during the second 
quarter of 2021, the Company concluded that the IPR&D was fully

impaired and recorded an impairment charge within research and development expenses in the consolidated statement of operations and comprehensive 
loss for the remaining balance of the IPR&D intangible asset June 30, 2021. The Company recognized IPR&D impairment charges of $2.3 million, $0.5 
million,  and  $0.7  million  for  the  quarters  ended  as  of  December  31,  2020,  March  31,  2021,  and  June  30,  2021.  On  July  29,  2021,  the  Company  sent 
Novartis a termination notice. Termination will automatically take effect as of 60 days from the date of delivery of the termination notice to Novartis, but in 
no event later than October 1, 2021 without any further notice or action required of either Novartis or the Company.

The contingent consideration for the CVR was valued using an income approach, leveraging the probability adjusted discounted cash flow used in the 
valuation  of  the  IPR&D  and  then  deducting  the  administrative  fee  to  be  retained  by  the  combined  company  and  other  permitted  deductions  in  order  to 
arrive  at  the  net  cash  expected  to  be  paid  out  to  the  CVR  holders.  The  probability  adjusted  cash  flow  includes  significant  estimates  and  assumptions 
pertaining to commercialization events and cash consideration received by the Company for the grant of rights to commercialize RTB101 during the term 
of the CVR Agreement (as discussed above). These cash flows were then discounted to present value using the same discount rate applied in the valuation 
of the IPR&D.

Transaction costs for the Merger were $7.1 million for the year ended December 31, 2020 and were expensed as incurred in general and administrative 

expenses in the consolidated statements of operations and comprehensive loss.

4. Fair Value Measurements

The Company determines the fair value of financial and non-financial assets and liabilities using the fair value hierarchy which establishes three level 

of inputs that may be used to measure fair value, as follows:

Level 1 — Observable inputs, such as quoted prices in active markets for identical assets or liabilities.

Level 2 — Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not 

active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 — Unobservable inputs which reflect management’s best estimate of what market participants would use in pricing the asset or liability at the 

measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable 

inputs to the extent possible as well as considers counterparty credit risk in its assessment of fair value.

Assets  and  liabilities  measured  at  fair  value  are  classified  in  their  entirety  based  on  the  lowest  level  of  input  that  is  significant  to  the  fair  value 
measurement.  The  Company’s  assessment  of  the  significance  of  a  particular  input  to  the  fair  value  measurement  in  its  entirety  requires  management  to 
make judgments and consider factors specific to the asset or liability.

The following tables present information about the Company’s financial assets and liabilities measured at fair value on a recurring basis and indicate

Included in cash and cash equivalents in the consolidated balance sheets
Included in short-term marketable debt securities in the consolidated balance sheets.

Money  market  funds  are  included  within  Level  1  of  the  fair  value  hierarchy  because  they  are  valued  using  quoted  market  prices.  Corporate  debt 
securities, commercial paper and asset-backed securities are classified within Level 2 of the fair value hierarchy as they take into consideration valuations 
obtained from third-party pricing services. The pricing services utilize industry standard valuation models, including both income-based and market-based 
approaches, for which all significant inputs are observable, either directly or indirectly, to estimate the fair value. These inputs include reported trades of 
and broker/dealer quotes on the same or similar securities, issuer credit spreads, benchmark securities, prepayment/default projections based on historical 
data and other observable inputs.

As part of the acquisition of resTORbio, the Company entered into a CVR Agreement and recorded the fair value of the CVR as part of consideration 
transferred. The Company considers the contingent consideration liability a Level 3 instrument (one with significant unobservable inputs) in the fair value 
hierarchy. In June 2021, the Company determined the possibility of any commercialization events for RTB101 was close to zero (see Note 3). As a result, 
the fair value of the CVR liability was adjusted to zero. On October 27, 2021, the Company provided a Termination Notice under the CVR Agreement to 
the joint rights agents to terminate its obligations under the CVR Agreement, effective immediately.

City, CA and other purposes permitted under the Loan Agreement, with an interest rate equal to the greater of 0.25% above the Prime Rate (as defined in 
the Loan Agreement) or 5.00%.  The Loan Agreement granted to Pacific Western Bank a security interest on substantially all of the Company’s assets other 
than intellectual property to secure the performance of the Company’s obligations under the Loan Agreement, and contains a variety of affirmative and 
negative  covenants,  including  required  financial  reporting,  limitations  on  certain  dispositions  of  assets  or  distributions,  limitations  on  the  incurrence  of 
additional debt or liens and other customary requirements. As of December 31, 2021, the Company was in compliance with such covenants.

Pursuant to the Loan Agreement in April 2020, the Company may request to draw upon the term loan at any time through the date eighteen months 
after the date of the Loan Agreement (Availability End Date), which was October 28, 2021. No amounts were drawn under the Loan Agreement through 
the Availability End Date.

On October 21, 2021, the Company amended the Loan Agreement with PacWest (the Loan Amendment) under which PacWest will provide one or 
more Term Loans, as well as Non-Formula Ancillary Services which shall not exceed $5.5 million in the aggregate. Non-Formula Ancillary Services are 
defined as automated clearinghouse transactions, corporate credit card services, letters of credit, or other treasury management services. The aggregate sum 
of the outstanding Term Loans and Non-Formula Ancillary Services shall at no time exceed $15.0 million, which each Term Loan to be in an amount of not 
less  than  $1.0  million.  As  of  December  31,  2021,  the  Company  had  outstanding  Non-Formula  Ancillary  Services  of  $4.4  million.  Accordingly,  as  of 
December 31, 2021, the Company has $10.6 million available under the Term Loan. Pursuant to the Loan Amendment, the interest rate for the Term Loans 
shall be set at an annual rate equal to the greater of (i) 0.25% above the Prime Rate then in effect and (ii) 4.25%.

As  of  December  31,  2021,  the  deferred  debt  issuance  costs  were  $0.1  million  and  are  included  in  other  non-current  assets  on  the  Company’s 

consolidated balance sheets.

10. Regeneron License and Collaboration Arrangement

Agreement Terms

On July 29, 2016, the Company entered into a license and collaboration agreement with Regeneron, which was amended in April 2019, with such 
amendment  becoming  effective  in  connection  with  Regeneron’s  investment  in  the  Company’s  Series  B  redeemable  convertible  preferred  stock  private 
placement transaction in July 2019 (as amended, the Regeneron Agreement).

Agreement Structure. The Regeneron Agreement has two principal components: (a) a research collaboration component under which the parties will 
research, develop, and commercialize next-generation engineered gamma delta immune cell therapeutics (ICPs), namely engineered gamma delta immune 
cells with CARs and TCRs directed to disease-specific cell surface antigens, which includes the grant of certain licenses to intellectual property between 
the two parties, and (b) for a certain period following the effective date, a license to the Company to use certain of Regeneron’s proprietary mice to develop 
and commercialize ICPs generated by the Company, with certain limitations relating to targets under the Regeneron Agreement.

Research Collaboration. Research activities under the collaboration are governed by research plans, which include the strategy, goals, activities, and 
responsibilities of the parties with respect to a target. The Company is primarily responsible for generating, validating, and optimizing ICPs, developing 
processes  for  manufacture  of  ICPs,  and  certain  preclinical  and  clinical  manufacturing  activities  for  ICPs;  Regeneron’s  key  responsibility  is  generating, 
validating, and optimizing CARs and TCRs that bind to the applicable target. The parties have formed a joint research committee to monitor and govern the 
research and development efforts during the research program term.

Rights to Research Targets. Under the terms of the collaboration, the parties will conduct research on mutually agreed upon targets. Regeneron may 
obtain  exclusive  rights  for  the  targets  that  it  chooses  in  accordance  with  the  target  selection  mechanism  set  forth  in  the  Regeneron  Agreement,  and  the 
Company similarly may obtain exclusive rights for targets it chooses in accordance with such target selection mechanism. The Company has the right to 
develop  and  commercialize  ICPs  to  the  first  collaboration  target  to  come  out  of  the  research  program.  On  January  28,  2022,  the  Company  received  a 
payment of $20.0 million from Regeneron for exercise of its option to license exclusive rights to ADI-002 and Regeneron potentially has additional options 
to other ICP targets under the Regeneron Agreement. Pursuant to the Agreement with Regeneron, the Company had the right to elect to co-fund ADI-002's 
future  development  costs.  The  Company  did  not  elect  its  option.  For  those  targets  it  does  not  have  an  option  to  license,  Regeneron  has  a  right  of  first 
negotiation for up to two targets. Regeneron has the right to terminate the research program in its entirety (a) for convenience on six months prior written 
notice given at any time after December 31, 2019, or (b) following a change of control (as defined in the Regeneron Agreement) of the Company. The 
parties mutually agreed to their first product declaration criteria for collaboration ICP, CD20, in 2018.

Rights  to  Company-Developed  Targets.  Regeneron  has  an  exclusive  license  to  use  targeting  moieties  generated  by  the  Company  by  its  use  of 

Regeneron’s proprietary mice to develop and commercialize non-ICPs.

F-22

 
Adicet Bio, Inc.
Notes to Consolidated Financial Statements

Exclusivity.  During  the  five-year  target  selection  period  that  expired  in  July  2021,  the  Company  may  not  directly  or  indirectly  research,  develop, 
manufacture or commercialize an ICP, or grant a license to do the foregoing, except pursuant to the agreement. For so long as either party is researching or 
developing an ICP to a target under the research program, neither party may research, develop, manufacture or commercialize any other ICP to such target, 
or grant a license to do the foregoing. And for so long as a party is researching, developing or commercializing an ICP to target that is licensed to it (and 
royalty bearing) under the agreement, neither party may research, develop, manufacture or commercialize any other ICP to such target, or grant a license to 
permit  another  party  to  do  the  foregoing.  These  exclusivity  obligations  are  limited  to  engineered  gamma  delta  immune  cells  to  targets  reasonably 
considered to have therapeutic relevance in oncology. The Regeneron Agreement includes certain exceptions to the exclusivity obligations of the parties, 
including with respect to targets that are rejected by one party in the target selection process, as well as protections in the event of a change of control of a 
party where the acquirer has a competing program.

Co-Funding and Profit Sharing. The Company has an option to co-fund specified portions of the future development costs for, and to co-promote, 
ICPs to a target for which Regeneron has exercised an option, and to participate in the profits for such target. The Company has the right to exercise this 
right  in  various  geographic  regions,  including  on  a  worldwide  basis.  In  the  event  the  Company  exercises  such  right,  the  parties  will  share  further 
development costs and profits proportionally to their co-funding percentages.

Financial  Terms.  The  Company  received  a  non-refundable  upfront  payment  of  $25.0  million  from  Regeneron  upon  execution  of  the  Regeneron 
Agreement  and  has  received  an  aggregate  of  $20.0  million  of  additional  payments  for  research  funding  from  Regeneron  as  of  December  31,  2021.  In 
addition, Regeneron may have to pay the Company additional amounts in the future consisting of up to an aggregate of $80.0 million of option exercise 
fees for a certain number of collaboration ICPs, as specified in the Regeneron Agreement. Regeneron must also pay the Company high single digit royalties 
as a percentage of net sales for ICPs to targets for which it has exclusive rights, and low single digit royalties as a percentage of net sales on any non-ICP 
product comprising a targeting moiety generated by the Company through the use of Regeneron’s proprietary mice. The Company must pay Regeneron 
mid-single  to  low  double  digit,  but  less  than  teens,  of  royalties  as  a  percentage  of  net  sales  of  ICPs  to  targets  for  which  the  Company  has  exercised 
exclusive rights, and low to mid-single digit of royalties as a percentage of net sales of targeting moieties generated from the Company’s license to use 
Regeneron’s proprietary mice. Royalties are payable until the longer of the expiration or invalidity of the licensed patent rights or twelve (12) years from 
first commercial sale.

Other Terms. The Regeneron Agreement contains customary representations, warranties and covenants by the Company and Regeneron and includes 
(i) an obligation of the Company to use commercially reasonable efforts to develop and commercialize at least one product based on a collaboration ICP 
that is not an optioned collaboration ICP for each collaboration target and (ii) an obligation of Regeneron to use commercially reasonable efforts to develop 
and commercialize at least one product based on an optioned collaboration ICP for each collaboration target. The Company and Regeneron are required to 
indemnify  the  other  party  against  all  losses  and  expenses  related  to  breaches  of  its  representations,  warranties  and  covenants  under  the  Regeneron 
Agreement.

Term  and  Termination.  The  term  of  the  Regeneron  Agreement  expires,  on  a  product-by-product  basis,  on  the  expiration  of  the  obligation  to  pay 
royalties for such product. The Regeneron Agreement is subject to early termination by either party upon uncured material breach by the other party. The 
licenses to develop and commercialize an ICP to a target that one party has exclusively licensed may be terminated by such party for convenience.

Equity  Investments.  In  connection  with  its  collaboration,  Regeneron  and  the  Company  entered  into  a  side  letter  pursuant  to  which,  among  other 
matters, Regeneron was granted certain stockholder rights and investment rights in connection with the Company’s next equity financing that met certain 
criteria  and  in  connection  with  an  initial  public  offering  by  the  Company.  Regeneron  exercised  its  investment  right  and  purchased  approximately  $10.0 
million of the Company’s Series B redeemable convertible preferred stock in a private placement transaction in July 2019. The remaining obligations under 
the side letter agreement terminated immediately prior to the Effective Time of the Merger.

Revenue Recognition

The Company identified the following material promises under the Regeneron Agreement: (1) a research license, (2) a collaboration invention license, 
(3) a trademark license, (4) research and development services during the research term, (5) manufacturing services to manufacture collaboration ICPs for 
the research programs, (6) participation in the joint research committee, and (7) information sharing during the research term. The Company considered 
that  the  licenses  granted  under  the  Regeneron  Agreement  are  not  capable  of  being  distinct  and  are  not  distinct  from  the  research  and  development  and 
manufacturing services within the context of the Regeneron Agreement, because 1) such licenses are for the research and development effort during the 
research term, unless Regeneron exercises its option under the Regeneron Agreement, 2) the research and development services significantly increase the 
utility  of  such  licenses,  and  3)  research  and  development  services  require  collaboration  ICPs  being  manufactured.  Specifically,  the  Company’s  granted 
licenses can only provide benefit to Regeneron in combination with the Company’s research and development and manufacturing services to discover the 
collaboration ICPs. Similarly, the participation in the joint research committee and information sharing are not capable of being distinct and are not distinct 
from 

F-23

 
Adicet Bio, Inc.
Notes to Consolidated Financial Statements

the research and development and manufacturing services within the context of the agreement, because the participation in the joint research committee is 
for monitoring and governing of the research and development efforts and the information sharing is for sharing results of such research and development 
efforts. Therefore, all of the promises above are combined into a single performance obligation.

The  Company  also  evaluated  whether  the  option  provided  to  Regeneron  represents  a  material  right  that  would  require  separate  deferral  and 
recognition.  The  option  exercise  will  provide  Regeneron  with  a  development  and  commercial  license  to  develop  and  commercialize  the  optioned 
collaboration ICPs. The Company concluded that the $25.0 million upfront payment to the Company was not negotiated to provide incremental discount 
for the future option fees payable upon Regeneron’s exercise of the option.

Regeneron could decide not to exercise the option at its own discretion. The exercise of the option by Regeneron is not certain and is dependent on 
many  factors,  such  as  progress  made  on  the  specific  option-eligible  collaboration  ICP,  Regeneron’s  overall  assessment  of  commercial  feasibility  of  the 
further  research,  development  and  commercialization  of  the  Option  products,  availability  and  cost  of  alternative  programs  and  products.  The  option 
provides Regeneron with a license for intellectual property that will be improved from the inception of the Regeneron Agreement. In addition, the option 
fee  is  significant  compared  to  the  sum  total  of  the  upfront  payment  and  research  funding  fees  in  the  original  Regeneron  Agreement.  Therefore,  the 
Company  determined  that  the  option  provided  to  Regeneron  does  not  represent  a  material  right  and  that  any  potential  exercise  of  the  option  should  be 
accounted  as  a  separate  contract.  Hence,  upon  the  option  exercise  by  Regeneron  the  option  fee  would  be  allocated  to  the  development  and  commercial 
license which would be the only performance obligation in that separate contract and recognized as revenue when control of the license rights is transferred 
to Regeneron.

For revenue recognition purposes, the Company determined that the duration of the contract is the same as the research term of five years beginning 
on the execution of the Regeneron Agreement on July 29, 2016. The contract duration is defined as the period during which parties to the contract have 
present and enforceable rights and obligations. For revenue recognition purposes, the five-year term has been extended to the first quarter of 2022 due to 
additional  time  required  to  complete  the  performance  obligation  under  the  Regeneron  Agreement.  The  Company  determined  that  Regeneron  faces 
significant in-substance penalties were it to terminate the Regeneron Agreement prior to the end of the research term.

At contract inception, the Company determined the transaction price of the Regeneron Agreement to be $55.0 million, consisting of the $25.0 million 
upfront payment and the aggregate research funding fees of $30.0 million payable over the research term. In order to determine the transaction price, the 
Company evaluated all the payments to be received during the duration of the contract. Per the terms of the original Regeneron Agreement prior to the 
amendment  effective  from  July  2019,  the  research  funding  fees  of  $30.0  million  were  payable  merely  due  to  the  passage  of  time  and  therefore  did  not 
represent a variable consideration. After the amendment became effective in July 2019, $20.0 million of these fees became contingent upon meeting certain 
development  and  regulatory  milestones.  Therefore,  the  Company  concluded  that  after  the  amendment  such  potential  payments  became  variable 
consideration. The receipt of the variable consideration was subject to substantial uncertainty and was therefore excluded from the transaction price upon 
the  effective  date  of  the  amendment.  Accordingly,  the  transaction  price  was  reduced  to  $35.0  million  in  July  2019.  The  Company  re-evaluates  the 
transaction  price  if  there  is  a  significant  change  in  facts  and  circumstances  at  least  at  the  end  of  each  reporting  period.  The  Company  increased  the 
transaction price by $10.0  million  in  June  2020  to  $45.0  million  when  it  achieved  the  milestone  for  the  selection  of  a  clinical  candidate  to  the  second 
collaboration target under the Regeneron Agreement, resulting in the recognition of an additional $5.0 million in revenue during the three months ended 
June 30, 2020. 

The  Company  also  considered  the  existence  of  any  significant  financing  component  within  the  Regeneron  Agreement  given  its  upfront  payment 
structure. Based upon this assessment, the Company concluded that the up-front payment was provided for valid business reasons and not for the purpose 
of providing financing. The reason for the initial advance payment at the beginning of the contract is not to provide financing to the Company, but to ensure 
Regeneron’s  commitment  to  the  contract  and  to  provide  assurance  that  the  customer  will  perform  its  obligations  under  the  contract.  Accordingly,  the 
Company  has  concluded  that  the  upfront  payment  structure  of  the  Regeneron  Agreement  does  not  result  in  the  existence  of  a  significant  financing 
component.

The royalty payments will be recognized when the related sales occur as they were determined to relate predominantly to the intellectual property 

licenses granted to Regeneron and therefore have also been excluded from the transaction price.

The  Company  has  determined  that  the  combined  performance  obligation  is  satisfied  over  time.  ASC  606  requires  the  Company  to  select  a  single 
revenue recognition method for the performance obligation that depicts the Company’s performance in transferring control of the services. Accordingly, the 
Company utilizes a cost-based input method to measure proportional performance and to calculate the corresponding amount of revenue to recognize. The 
Company believes this is the best measure of progress because it reflects how the Company transfers its performance obligation to Regeneron. In applying 
the cost-based input method of revenue recognition, the Company uses actual costs incurred relative to budgeted costs to fulfill the combined performance 
obligation. These costs consist primarily of internal full-time equivalent effort and third-party contract costs. Revenue is recognized based on actual costs 
incurred as a percentage of total budgeted costs as the Company completes its 

F-24

Notes to Consolidated Financial Statements

performance obligations over the research term of five years. A cost-based input method of revenue recognition requires management to make estimates of 
costs to complete the Company’s performance obligations. In making such estimates, significant judgment is required to evaluate assumptions related to 
cost estimates. The cumulative effect of revisions to estimated costs to complete the Company’s performance obligations will be recorded in the period in 
which  changes  are  identified  and  amounts  can  be  reasonably  estimated.  A  significant  change  in  these  assumptions  and  estimates  could  have  a  material 
impact on the timing and amount of revenue recognized in future periods.

(1)  Deductions to contract liabilities relate to deferred revenue recognized as revenue during the reporting period.

As  of  December  31,  2021,  contract  liabilities  related  to  the  Regeneron  Agreement  of  $4.8  million  was  comprised  of  the  $25.0  million  upfront 
payment, $10.0 million in total research funding fees for fiscal years 2017 and 2018, and $10.0 million for achievement of the milestone for the selection of 
a clinical candidate for the second collaboration target in June 2020, less $40.2 million of cumulative license and collaboration revenue recognized from the 
inception of the Regeneron Agreement as of December 31, 2021 and will be recognized as the combined performance obligation is satisfied.  

As  of  December  31,  2020,  contract  liabilities  related  to  the  Regeneron  Agreement  of  $14.0  million  was  comprised  of  the  $25.0  million  upfront 
payment, $10.0 million in total research funding fees for fiscal years 2017 and 2018, and $10 million for achievement of the milestone for the selection of a 
clinical candidate to the second collaboration target in June 2020, less $31.0 million of cumulative license and collaboration revenue recognized from the 
inception of the Regeneron Agreement as of December 31, 2020.

For  the  years  ended  December  31,  2021  and  2020,  the  Company  recognized  $9.2 million and $17.9  million  of  license  and  collaboration  revenue, 
respectively, from amounts included in the contract liability balances at the beginning of the period. There were no costs to obtain or fulfill the contract that 
meet the criteria to be capitalized.

11. License, Funding and Other Agreements Related to the CVR

Contingent Value Rights Agreement

As discussed in Note 3, in connection with the Merger, the Company entered into the CVR Agreement with Computershare Inc. and Computershare 
Trust Company, N.A. as joint rights agent. The CVR holders are entitled to receive net proceeds from the commercialization, if any, received from a third-
party  commercial  partner  of  RTB101  for  a  COVID-19  related  indication.  The  total  fees  and  expenses  of  the  Company’s  clinical  trials  for  a  COVID-19 
related indication of RTB101 is limited to $3.0 million under the CVR Agreement. Through October 31, 2020, the Company’s total accumulated spend was 
$1.1 million of expenses. In November 2020, management terminated the nursing home study due to slow enrollment and as a consequence lowered the 
probability of finding a partner due to the delay in time to commercialization of RTB101. In February 2021, management terminated the National Institute 
on Aging study of RTB101 for COVID-19 post-exposure prophylaxis in adults age 65 years and older due to poor enrollment. In March 2021, management 
estimated that the probability of finding a partner should be further reduced. As a result, the fair value of the CVR liability was decreased by $0.4 million to 
$0.6  million.  In  June  2021,  the  Company  determined  the  possibility  of  any  commercialization  events  for  RTB101  was  close  to  zero  (see  Note  3).  As  a 
result, the fair value of the CVR liability was adjusted to zero.

On October 27, 2021, the Company provided a Termination Notice under the CVR Agreement to the joint rights agent to terminate its obligations 

under the CVR Agreement, effective immediately.

Novartis License Agreement

On March 23, 2017, resTORbio entered into an exclusive license agreement with Novartis International Pharmaceutical Ltd. (Novartis). Under the 

agreement, Novartis granted resTORbio an exclusive, field-restricted, worldwide license, to certain 

F-25

Notes to Consolidated Financial Statements

intellectual property rights owned or controlled by Novartis, to develop, commercialize and sell one or more therapeutic products comprising RTB101 or 
RTB101 in combination with everolimus in a fixed dose combination. The exclusive field under the license agreement is for the treatment, prevention and 
diagnosis of disease and other conditions in all indications in humans and animals.

The agreement may be terminated by either party upon a material breach of obligation by the other party that is not cured with 60 days after written 
notice. resTORbio may terminate the agreement in its entirety or on a product-by-product or country-by-country basis with or without cause with 60 days’ 
prior written notice. 

As consideration for the license, resTORbio is required to pay up to an aggregate of $4.3 million upon the satisfaction of clinical milestones, up to an 
aggregate of $24 million upon the satisfaction of regulatory milestones for the first indication approved, and up to an aggregate of $18 million upon the 
satisfaction of regulatory milestones for the second indication approved. In addition, resTORbio is required to pay up to an aggregate of $125 million upon 
the satisfaction of commercial milestones, based on the amount of annual net sales. resTORbio is also required to pay tiered royalties ranging from a mid-
single digit percentage to a low-teen digit percentage on annual net sales of products. These royalty obligations last on a product-by-product and country-
by-country  basis  until  the  latest  of  (i)  the  expiration  of  the  last  valid  claim  of  a  Novartis  patent  covering  a  subject  product,  (ii)  the  expiration  of  any 
regulatory  exclusivity  for  the  subject  product  in  a  country,  or  (iii)  the  10th  anniversary  of  the  first  commercial  sale  in  the  country,  and  are  subject  to  a 
reduction after the expiration of the last valid claim of a Novartis patent or the introduction of a generic equivalent of a product in a country. 

On July 27, 2021, the Company sent Novartis a termination notice. Termination automatically took effect on September 25, 2021, 60 days from the 

date of delivery of the termination notice to Novartis, without further notice of action required of either Novartis or the Company.

National Institute of Health

In May 2019, resTORbio was awarded a 5-year grant for up to $1.5 million from the NIH to study RTB101 and the regulation of antiviral immunity in 
the elderly. resTORbio is entitled to use the award solely to conduct the research and is solely responsible for commencing and conducting the research and 
will furnish periodic progress updates to the NIH throughout the term of the award. After completing the research, resTORbio must provide the NIH with a 
formal report describing the work performed and the results of the research.

For funds received under the NIH funding agreement, resTORbio recognizes a reduction in research and development expenses in an amount equal to 
the qualifying expenses incurred in each period up to the amount funded by the NIH. Qualifying expenses incurred by resTORbio in advance of funding by 
the NIH are recorded in the consolidated balance sheets as other current assets. For the year ended December 31, 2021, $0.4 million qualifying expenses 
have been incurred and $0.5 million have been funded by the NIH. The difference in the amount incurred by the Company and funded by the NIH was due 
to timing of requesting reimbursements from the NIH. On a cumulative basis as of December 31, 2021, $1.3 million has been incurred and $1.3 million has 
been funded by the NIH.

12. Commitments and Contingencies

Operating Leases

The  Company  leases  office  and  laboratory  space  in  Menlo  Park,  CA,  Redwood  City,  CA,  and  Boston,  MA.  As  of  December  31,  2021,  except  as 
described below, there have been no material changes in lease obligation from those disclosed in Note 12 to consolidated financial statements included in 
the Company's Annual Report on Form 10-K for the year ended December 31, 2020.

On June 25, 2021, the Company entered into an amendment to the Menlo Park lease to extend the term of the lease from March 31, 2022 to June 30, 
2022 and replace the previously leased premises (known as 173 and 175-177 Jefferson Drive) with another nearby premises (known as 235 Constitution 
Drive). The lease commenced on July 15, 2021 and expires on June  30,  2022.  In  connection  with  these  changes,  the  Company  will  incur  monthly  rent 
payments ranging from $87,286 to $89,904, increasing over the remaining term of the lease. Given the lease is short-term in nature, the Company is using 
the practical expedient for the lease and has not recorded a right of use asset or lease liability. Therefore, the Company will recognize rent expense on a 
straight-line basis over the lease term.

On July 19, 2021, the Company entered into a Sublease (the Sublease Agreement) with RFS OPCO LLC (Sublessee), whereby the Company agreed 
to sublease to Sublessee all of the 9,501 rentable square feet of office space in Boston, MA, currently leased by the Company pursuant to the Company’s 
lease with 500 Boylston & 222 Berkeley Owner (DE) LLC, dated January 8, 2018, as amended (the Master Lease). The term of the sublease started on 
September 1, 2021 and ends on July 30,

2026. The  aggregate  base  rent  due  to  the  Company  under  the  Sublease  is  approximately  $3.5  million  starting  October  1,  2021.  The  Company  records 
sublease income as a reduction of lease expense. Upon execution of the Sublease Agreement, the Company received a cash security deposit of $0.1 million 
from  the  Subleasee  which  is  recorded  as  other  non-current  liabilities  in  the  consolidated  balance  sheets.  The  expected  undiscounted  cash  flows  to  be 
received from the sublease as of December 31, 2021 is as follows (in thousands):

The Company maintains letters of credit of $4.1 million, $0.2 million, and $0.2 million in connection with the Company’s office leases in Redwood 
City, CA, Menlo Park, CA, and  Boston, MA, respectively. As of December 31, 2021, the cash amount associated with the Menlo Park Lease is recorded as 
restricted cash on the consolidated balance sheet. As of December 31, 2020, all cash amounts are recorded as restricted cash on the consolidated balance 
sheet. 

Indemnification Agreements

In the ordinary course of business, the Company enters into agreements that may include indemnification provisions. Pursuant to such agreements, the 
Company may indemnify, hold harmless and defend an indemnified party for losses suffered or incurred by the indemnified party. Some of the provisions 
will  limit  losses  to  those  arising  from  third-party  actions.  In  some  cases,  the  indemnification  will  continue  after  the  termination  of  the  agreement.  The 
maximum  potential  amount  of  future  payments  the  Company  could  be  required  to  make  under  these  provisions  is  not  determinable.  The  Company  has 
never  incurred  material  costs  to  defend  lawsuits  or  settle  claims  related  to  these  indemnification  provisions.  The  Company  has  also  entered  into 
indemnification agreements with its directors and officers that require the Company, among other things, to indemnify them against certain liabilities that 
may arise by reason of their status or service as directors or officers to the fullest extent permitted by Delaware corporate law. The Company currently has 
directors’ and officers’ liability insurance.

Legal Proceedings

In connection with the Merger, seven lawsuits were filed against the Company, its directors, Former Adicet, and/or Merger Sub. which were either 

dismissed or settled for of $0.2 million in the fourth quarter of 2020.

Summary of Plans

The Plans are administered by the Board of Directors or, at the discretion of the Board of Directors, by a committee of the Board of Directors. The 
exercise prices, vesting and other restrictions are determined at the discretion of the Board of Directors, or its committee if so delegated, except that the 
exercise price per share of stock options may not be less than 100% of the fair market value of the share of common stock on the date of grant and the term 
of  the  stock  option  may  not  be  greater  than  ten  years.  Incentive  stock  options  granted  to  employees  and  restricted  stock  awards  granted  to  employees, 
officers,  members  of  the  Board  of  Directors,  advisors,  and  consultants  of  the  Company  typically  vest  over  four  years.  Non-statutory  options  granted  to 
employees, officers, members of the Board of Directors, advisors, and consultants of the Company typically vest over three or four years. Shares that are 
expired, terminated, surrendered or canceled under the Plans without having been fully exercised will be available for future awards. In addition, shares of 
common stock that are tendered to the Company by a participant to exercise an award are added to the number of shares of common stock available for the 
grant of awards.

The 2017 Plan and 2018 Plan

In 2017, resTORbio adopted the 2017 Plan. In connection with resTORbio’s initial public offering completed in January 2018, the resTORbio Board 
adopted and resTORbio’s stockholders approved the 2018 Plan. The 2018 Plan provides that the number of shares reserved and available for issuance under 
the plan will automatically increase each January 1, beginning on January 1, 2019, by 4% of the outstanding number of shares of resTORbio’s common 
stock  on  the  immediately  preceding  December  31  or  such  lesser  number  of  shares  as  determined  by  the  Board.  On  April  27,  2021,  the  stockholders 
approved an amendment and restatement of the 2018 Stock Option and Incentive Plan, to, among other things, increase the aggregate number of shares 
authorized for issuance under the 2018 Plan by 1,500,000 shares, plus on January 1, 2022 and each January 1, thereafter, the number of shares authorized

December 31, or such lesser number as determined by the compensation committee. On January 1, 2022, the number of shares reserved and available for 
issuance under the 2018 Plan automatically increased by 1,986,845 shares of Common Stock equal to 5% of the number of shares of Common Stock issued 
and outstanding on December 31, 2021.

Since  the  date  of  effectiveness  of  the  2018  Plan,  resTORbio  has  not  and  the  Company  will  not  grant  any  further  awards  under  the  2017  Plan. 
However, any shares of common stock subject to awards under the 2017 Plan that expire, terminate, or otherwise are surrendered, canceled, forfeited or 
repurchased without having been fully exercised or resulting in any common stock being issued will become available for issuance under the 2018 Plan. As 
of December 31, 2021, there are no outstanding options under the 2017 Plan.

As of December 31, 2021, the number of shares of common stock available for grant under the 2017 and 2018 Plan is 1,683,999. As of December 31, 
2021, an aggregate of 2,574,170 shares of common stock were issuable upon the exercise of outstanding stock options under the 2017 Plan and 2018 Plans 
at  a  weighted  average  exercise  price  of  $15.10  per  share.  In  addition  to  this  amount,  as  of  December  31,  2021,  771,660  shares  of  common  stock  were 
issuable upon the vesting of 6,410 performance stock units (PSUs) granted in May 2021, 205,250 RSUs granted in August 2021, and 560,000 RSUs and 
PSUs granted in October 2021. 

The 2014 Plan and 2015 Plan

As of December 31, 2021, the number of shares of common stock available for grant under the 2014 and 2015 Plan is 277,339. As of December 31, 
2021, an aggregate of 915,657 shares of common stock were issuable upon the exercise of outstanding stock options under the 2015 plan at a weighted 
average exercise price of $11.46 per share and an aggregate of 22,987 shares of common stock were issuable upon the exercise of outstanding stock options 
under the 2014 Plan at a weighted average exercise price of $1.61 per share.

Since the date of effectiveness of the Merger, the Company has not and will not grant any further awards under the 2014 Plan.

2018 Employee Stock Purchase Plan

The  2018  ESPP  provides  that  the  number  of  shares  reserved  and  available  for  issuance  will  automatically  increase  each  January  1,  beginning  on 
January  1,  2019  and  increasing  each  January  1  thereafter  through  January  1,  2028,  by  the  least  of  (i)  1%  of  the  outstanding  number  of  shares  of  the 
Company’s  common  stock  on  the  immediately  preceding  December  31;  (ii)  77,703  shares  or  (iii)  such  number  of  shares  as  determined  by  the  ESPP 
administrator. 

 On January 1, 2020, as a result of the foregoing evergreen provision, the number of shares of common stock available for issuance under the 2018 

ESPP automatically increased from 79,369 to 131,432 shares. On January 1, 2021, as a result of the

foregoing evergreen provision, the number of shares of common stock available for issuance under the 2018 ESPP automatically increased from 131,432 to 
524,775. During the 2021 Annual Meeting of the stockholders held on April 27, 2021, the stockholders approved an amendment and restatement of the 
Company's 2018 ESPP. As a result, the Company increased the shares available for issuance under the 2018 ESPP to 524,775 shares. 

For the year ended December 31, 2021 the Company issued a total of 15,667 shares under the 2018 ESPP. Expense related to the issuance of such 

shares was less than $0.1 million. No shares were issued under the 2018 ESPP during the year ended December 31, 2020.

The fair value of each stock option was estimated at the date of grant using a Black-Scholes option-pricing model using the following assumptions:

Expected  volatility.  The  Company  has  limited  trading  history.  As  such,  the  expected  volatility  was  determined  by  examining  the  historical 
volatilities  for  comparable  publicly  traded  companies  within  the  biotechnology  and  pharmaceutical  industry  using  an  average  of  historical 
volatilities of the Company’s industry peers.

Risk-free interest rate. The risk-free interest rate is based on the United States Treasury yield with a maturity equal to the expected term of the 
option in effect at the time of grant.

Dividend yield. The expected dividend is assumed to be zero as dividends have never been paid and there are no current plans to pay dividends 
on common stock.

Expected  term.  The  expected  term  represents  the  period  that  the  stock-based  awards  are  expected  to  be  outstanding.  The  expected  term  is 
calculated  using  the  simplified  method  which  is  used  when  there  is  insufficient  historical  data  about  exercise  patterns  and  post-vesting 
employment  termination  behavior.  The  simplified  method  is  based  on  the  vesting  period  and  the  contractual  term  for  each  grant,  or  for  each 
vesting-tranche for awards with graded vesting. The mid-point between the vesting date and the maximum contractual expiration date is used as 
the  expected  term  under  this  method.  For  awards  with  multiple  vesting-tranches,  the  times  from  grant  until  the  mid-points  for  each  of  the 
tranches may be averaged to provide an overall expected term.

The Company will continue to use judgment in evaluating the expected volatility, risk-free interest rates, dividend yield and expected term, utilized for 

stock-based compensation on a prospective basis.

The  aggregate  intrinsic  value  is  calculated  as  the  difference  between  the  exercise  price  of  the  underlying  stock  options  and  the  fair  value  of  the 
Company’s  common  stock  for  stock  options  that  were  in-the-money  at  December  31,  2021  and  2020.  The  aggregate  intrinsic  value  of  stock  options 
exercised during the years ended on December 31, 2021 and 2020 was $10.1 million and $2.5 million, respectively.

The total fair value of options that vested during the years ended December 31, 2021 and 2020 was $2.3 million and $2.4 million, respectively. The 
options granted during the years ended December 31, 2021 and 2020 had a weighted-average per share grant-date fair value of $9.68 per share and $9.96 
per share, respectively. 

As of December 31, 2021, the total unrecognized stock-based compensation expense related to unvested stock options was $24.8 million, which is 

expected to be recognized over the remaining weighted-average vesting period of 2.8 years.

In  May  2021,  the  Company  granted  6,410  RSUs  with  service  and  performance  conditions  to  an  employee,  none  of  which  vested  during  the  year 
ending December 31, 2021. Vesting of these awards is contingent on the occurrence of certain milestone events and fulfilment of any remaining service 
condition. As a result, the related compensation cost is recognized as an expense when achievement of the milestone is considered probable. The expense 
recognized for these awards is based on the grant date fair value of the Company's common stock multiplied by the number of units granted. The Company 
recognized less than $0.1 million of related expense during the year ended December 31, 2021.

In October 2021, the Company granted 560,000 RSUs with service and performance conditions to certain employees, none of which vested during the 
year ended December 31, 2021. Vesting of these awards is contingent on the occurrence of certain milestone events and fulfilment of any remaining service 
condition. As a result, the related compensation cost is recognized as an expense when achievement of the milestone is considered probable. The expense 
recognized for these awards is based on the grant date fair value of the Company's common stock multiplied by the number of units granted. The Company 
recognized $1.6 million of related expense during the year ended December 31, 2021. 

The weighted-average grant date fair value of RSUs granted during the year ended December 31, 2021 was $7.84. There was no RSU activity during 

the year ended December 31, 2020. Additionally, no RSUs vested during the year ended December 31, 2021. 

As  of  December  31,  2021,  there  was  approximately  $4.1  million  of  unrecognized  compensation  cost  related  to  unvested  RSUs  that  the  Company 

expects to recognize over a remaining weighted-average period of approximately 1.3 years.

Income tax benefit of $0.1 million for the year ended December 31, 2021 is primarily due to the adjustment in deferred tax liability arising from the 

impairment charge of $1.2 million of acquired IPR&D. In contrast, the income tax benefit of $2.8 million for the year ended December 31, 2020 was 
primarily due to a the recognition of a net operating loss carryback under the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) which 
was enacted on March 27, 2020 in response to the COVID-19 pandemic.

On September 15, 2020 Adicet Bio and resTORbio completed the Merger upon which Adicet Bio became the parent company of the consolidated 

group. The Merger did not create a step up in basis for tax basis of the asset as it was considered a tax-free merger. The above deferred tax table includes 
deferred related to resTORbio.

The Company has established a valuation allowance against its deferred tax assets due to the uncertainty surrounding the realization of such assets.

ASC 740 requires that the tax benefit of net operating losses, temporary differences and credit carryforwards be recorded as an asset to the extent that 

management assesses that realization is “more likely than not.” Realization of the future tax benefits is dependent on the Company’s ability to generate 
sufficient taxable income within the carryforward period. Because of the Company’s recent history of operating losses, management believes that 
recognition of the deferred tax assets arising from the above-mentioned future tax benefits is currently not likely to be realized and, accordingly, has 
provided a valuation allowance.

The valuation allowance increased by $15.5 million during 2021 and $37.9 million during 2020.

As of December 31, 2021, the Company had net operating loss carryforwards of $271.6 million, $143.5 million, and $17.1 million to reduce future 
taxable income, if any, for federal, state and foreign income tax purposes, respectively. Of the federal net operating loss carryforwards, $7.6 million will 
begin to expire in 2036 if not utilized, and $264.0 million can be carried forward indefinitely. The state carryforwards will begin to expire in 2035.

The Company also had approximately $1.8 million of federal and $1.5 million of California research and development tax credit carryforwards 
available to offset future taxable income as of December 31, 2021. The federal credits begin to expire in 2041 and the California research credits can be 
carried forward indefinitely.

Utilization of the net operating loss carryforwards and research and development tax credit carryforwards may be subject to an annual limitation under 

Section 382 of the Internal Revenue Code of 1986, and corresponding provisions of state law, due to ownership changes that have occurred previously or 
that could occur in the future. These ownership changes may limit the amount of carryforwards that can be utilized annually to offset future taxable income. 
In general, an ownership change, as defined by Section 382, results from transactions increasing the ownership of certain shareholders or public groups in 
the stock of a corporation by more than 50% over a three-year period. The Company has not conducted a study to assess whether a change of control has 
occurred or whether there have been multiple changes of control since inception due to the significant complexity and cost associated with such a study. If 
the Company has experienced a change of control, as defined by Section 382, at any time since inception, utilization of the net operating loss carryforwards 
or research and development tax credit carryforwards would be subject to an annual limitation under Section 382, which is determined by first multiplying 
the value of the Company’s stock at the time of the ownership change by the applicable long-term tax-exempt rate, and then could be subject to additional 
adjustments, as required. Any limitation may result in expiration of a portion of the net operating loss carryforwards or research and development tax credit 
carryforwards before utilization. Further, until a study is completed and any limitation is known, no liability related to uncertain tax positions is recorded in 
the consolidated financial statements. The Company does not expect its unrecognized tax benefit balance to change materially over the next 12 months.

The Company files income tax returns in the United States federal jurisdiction, California, Massachusetts, New York and Israel. The tax years 2015 to 

2021 remains open to United States federal and state examination to the extent of the utilization of net operating loss and credit carryovers.

As of December 31, 2021, the Company had unrecognized tax benefits of $0.8 million related to the transfer of certain intellectual property from its 
Israeli subsidiary. In addition, as of December 31, 2021, the Company had unrecognized tax benefits of $3.2 million related to the federal and state research 
and development credits as a result of no formal research credit study performed.

18. Defined Contribution Plan

The Company maintains a defined contribution plan under Section 401(k) of the Internal Revenue Code covering substantially all full-time United 
States employees. Employee contributions are voluntary and are determined on an individual basis subject to the maximum allowable under federal tax 
regulations. During the year ended December 31, 2021 the Company made aggregate matching contributions of $0.3 million. The Company did not make 
contributions to the 401(k) plan during 2020.

19. Related Party Transactions 

As of December 31, 2021, Regeneron owned 883,568 shares of the Company's common stock. Regeneron became a related party in July 2019 as a 
result of Series B redeemable convertible preferred stock financing. Upon closing the Merger, 7,125,552 shares of the redeemable convertible preferred 
stock converted into 883,568 shares of the Company’s common stock. For the years ended December 31, 2021 and 2020, the Company recorded revenue 
related  to  the  Regeneron  Agreement  of  $9.7  million  and  $17.9  million,  respectively.  As  of  December  31,  2021,  the  Company  recorded  less  than  $0.2 
million in accounts receivable and has deferred revenue of $4.8 million related to the Regeneron Agreement (See Note 10).

On  January  28,  2022,  Regeneron  exercised  its  option  to  license  the  exclusive,  worldwide  rights  to  ADI-002,  an  allogeneic  gamma  delta  chimeric 

antigen receptor (CAR) T cell therapy directed against Glypican-3, pursuant to the Regeneron Agreement.
 In conjunction with the exercise of the Option, Regeneron paid an exercise fee of $20.0 million to the Company on January 28, 2022. 

Pursuant to the Regeneron Agreement, upon Regeneron’s exercise of the option, the Company had a specified period of time to elect to co-fund ADI-
002’s future development costs, and to participate in any potential profits with Regeneron up to a specified co-funding percentage in various geographic 
regions, including on a worldwide basis (Co-Funding Option). Adicet elected not to exercise its Co-Funding Option for ADI-002. Accordingly, Regeneron 
is responsible, at its sole cost, for all development, manufacturing and commercialization of ADI-002 and must pay the Company high single digit royalties 
as a percentage of any net sales of ADI-002 for a period commencing on the first commercial sale until the longer of (i) the expiration or invalidity of the 
licensed patent rights or (ii) a low double digit amount of years from first commercial sale.

SECTION 2.  ADMINISTRATION OF PLAN; ADMINISTRATOR AUTHORITY TO SELECT GRANTEES AND DETERMINE AWARDS

(a) Administration of Plan. The Plan shall be administered by the Administrator.

(b) Powers of Administrator. The Administrator shall have the power and authority to grant Awards consistent with the terms of the Plan, including the 
power and authority:

(i) to select the individuals to whom Awards may from time to time be granted;

(ii) to determine the time or times of grant, and the extent, if any, of Incentive Stock Options, Non-Qualified Stock Options, Stock Appreciation Rights, 
Restricted Stock Awards, Restricted Stock Units, Unrestricted Stock Awards, Cash-Based Awards and Dividend Equivalent Rights, or any combination of 
the foregoing, granted to any one or more grantees;

(iii) to determine the number of shares of Stock to be covered by any Award;

(iv) to determine and modify from time to time the terms and conditions, including restrictions, not inconsistent with the terms of the Plan, of any Award, 
which terms and conditions may differ among individual Awards and grantees, and to approve the forms of Award Certificates;

(v) to accelerate at any time the exercisability or vesting of all or any portion of any Award;

(vi) subject to the provisions of Section 5(c), to extend at any time the period in which Stock Options may be exercised; and

(vii) at any time to adopt, alter and repeal such rules, guidelines and practices for administration of the Plan and for its own acts and proceedings as it shall 
deem advisable; to interpret the terms and provisions of the Plan and any Award (including related written instruments); to make all determinations it 
deems advisable for the administration of the Plan; to decide all disputes arising in connection with the Plan; and to otherwise supervise the administration 
of the Plan.

All decisions and interpretations of the Administrator shall be binding on all persons, including the Company and Plan grantees.

(c) Delegation of Authority to Grant Awards. Subject to applicable law, the Administrator, in its discretion, may delegate to a committee consisting of one 
or more officers of the Company, including the Chief Executive Officer of the Company, all or part of the Administrator’s authority and duties with respect 
to the granting of Awards to individuals who are (i) not subject to the reporting and other provisions of Section 16 of the Exchange Act and (ii) not 
members of the delegated committee. Any such delegation by the Administrator shall include a limitation as to the amount of Stock underlying Awards that 
may be granted during the period of the delegation and shall contain guidelines as to the determination of the exercise price and the vesting criteria. The 
Administrator may revoke or amend the terms of a delegation at any time but such action shall not invalidate any prior actions of the Administrator’s 
delegate or delegates that were consistent with the terms of the Plan.

(d) Award Certificate. Awards under the Plan shall be evidenced by Award Certificates that set forth the terms, conditions and limitations for each Award 
which may include, without limitation, the term of an Award and the provisions applicable in the event employment or service terminates.

(e) Indemnification. Neither the Board nor the Administrator, nor any member of either or any delegate thereof, shall be liable for any act, omission, 
interpretation, construction or determination made in good faith in connection with the Plan, and the members of the Board and the Administrator (and any 
delegate thereof) shall be entitled in all cases to indemnification and reimbursement by the Company in respect of any claim, loss, damage or expense 
(including, without limitation, reasonable attorneys’ fees) arising or resulting therefrom to the fullest extent permitted by law and/or under the Company’s 
articles or bylaws or any directors’ and officers’ liability insurance coverage which may be in effect from time to time and/or any indemnification 
agreement between such individual and the Company.

(f) Foreign Award Recipients. Notwithstanding any provision of the Plan to the contrary, in order to comply with the laws in other countries in which the 
Company and its Subsidiaries operate or have employees or other individuals eligible for Awards, the Administrator, in its sole discretion, shall have the 
power and authority to: (i) determine which Subsidiaries shall be covered by the Plan; (ii) determine which individuals outside the United States are 
eligible to participate in the Plan; (iii) modify the terms and conditions of any Award granted to individuals outside the United States to comply with 
applicable foreign laws; (iv) establish 

ACTIVE/115808348.2 

 
 
subplans and modify exercise procedures and other terms and procedures, to the extent the Administrator determines such actions to be necessary or 
advisable (and such subplans and/or modifications shall be attached to this Plan as appendices); provided, however, that no such subplans and/or 
modifications shall increase the share limitations contained in Section 3(a) hereof; and (v) take any action, before or after an Award is made, that the 
Administrator determines to be necessary or advisable to obtain approval or comply with any local governmental regulatory exemptions or approvals. 
Notwithstanding the foregoing, the Administrator may not take any actions hereunder, and no Awards shall be granted, that would violate the Exchange Act 
or any other applicable United States securities law, the Code, or any other applicable United States governing statute or law.

SECTION 3.  STOCK ISSUABLE UNDER THE PLAN; MERGERS; SUBSTITUTION

(a) Stock Issuable. The maximum number of shares of Stock reserved and available for issuance under the Plan shall be 5,136,003 shares of Stock (the 
“Initial Limit”), subject to adjustment as provided in Section 3(c), plus on January 1, 2022 and each January 1 thereafter, the number of shares of Stock 
reserved and available for issuance under the Plan shall be cumulatively increased by 5% of the number of shares of Stock issued and outstanding on the 
immediately preceding December 31 (the “Annual Increase”). Subject to such overall limitation, the maximum aggregate number of shares of Stock that 
may be issued in the form of Incentive Stock Options shall not exceed the Initial Limit cumulatively increased on January 1, 2022 and on each January 1 
thereafter by the lesser of the Annual Increase for such year or 3,150,000 shares of Stock, subject in all cases to adjustment as provided in Section 3(c). For 
purposes of this limitation, the shares of Stock underlying any Awards that are forfeited, canceled, held back upon exercise of an Option or settlement of an 
Award to cover the exercise price or tax withholding, reacquired by the Company prior to vesting, satisfied without the issuance of Stock or otherwise 
terminated (other than by exercise) under each of the Plan and the 2017 Plan shall be added back to the shares of Stock available for issuance under the 
Plan. In the event the Company repurchases shares of Stock on the open market, such shares shall not be added to the shares of Stock available for issuance 
under the Plan. Subject to such overall limitations, shares of Stock may be issued up to such maximum number pursuant to any type or types of Award. The 
shares available for issuance under the Plan may be authorized but unissued shares of Stock or shares of Stock reacquired by the Company.

(b) Maximum Awards to Non-Employee Directors. Notwithstanding anything to the contrary in this Plan, the value of all Awards awarded under this Plan 
and all other cash compensation paid by the Company to any Non-Employee Director in any calendar year shall not exceed $1,000,000. For the purpose of 
this limitation, the value of any Award shall be its grant date fair value, as determined in accordance with ASC 718 or successor provision but excluding the 
impact of estimated forfeitures related to service-based vesting provisions.

(c) Changes in Stock. Subject to Section 3(d) hereof, if, as a result of any reorganization, recapitalization, reclassification, stock dividend, stock split, 
reverse stock split or other similar change in the Company’s capital stock, the outstanding shares of Stock are increased or decreased or are exchanged for a 
different number or kind of shares or other securities of the Company, or additional shares or new or different shares or other securities of the Company or 
other non-cash assets are distributed with respect to such shares of Stock or other securities, or, if, as a result of any merger or consolidation, sale of all or 
substantially all of the assets of the Company, the outstanding shares of Stock are converted into or exchanged for securities of the Company or any 
successor entity (or a parent or subsidiary thereof), the Administrator shall make an appropriate or proportionate adjustment in (i) the maximum number of 
shares reserved for issuance under the Plan, including the maximum number of shares that may be issued in the form of Incentive Stock Options, (ii) the 
number and kind of shares or other securities subject to any then outstanding Awards under the Plan, (iii) the repurchase price, if any, per share subject to 
each outstanding Restricted Stock Award, and (iv) the exercise price for each share subject to any then outstanding Stock Options and Stock Appreciation 
Rights under the Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied by the number of shares subject to Stock Options 
and Stock Appreciation Rights) as to which such Stock Options and Stock Appreciation Rights remain exercisable. The Administrator shall also make 
equitable or proportionate adjustments in the number of shares subject to outstanding Awards and the exercise price and the terms of outstanding Awards to 
take into consideration cash dividends paid other than in the ordinary course or any other extraordinary corporate event. The adjustment by the 
Administrator shall be final, binding and conclusive. No fractional shares of Stock shall be issued under the Plan resulting from any such adjustment, but 
the Administrator in its discretion may make a cash payment in lieu of fractional shares.

(d) Mergers and Other Transactions. In the case of and subject to the consummation of a Sale Event, the parties thereto may cause the assumption or 
continuation of Awards theretofore granted by the successor entity, or the substitution of such Awards with new Awards of the successor entity or parent 
thereof, with appropriate adjustment as to the number and kind of shares and, if appropriate, the per share exercise prices, as such parties shall agree. To the 
extent the parties to such Sale Event do not provide for the assumption, continuation or substitution of Awards, upon the effective time of the Sale Event, 
the Plan and all outstanding Awards granted hereunder shall terminate. In such case, except as may be otherwise provided in the relevant Award Certificate, 
all Options and Stock Appreciation Rights with time-based vesting conditions or restrictions that are not vested and/or exercisable immediately prior to the 
effective time of the Sale Event shall become fully vested and exercisable as of the effective time of the Sale Event, all other Awards with time-based 
vesting, conditions or restrictions shall become fully vested and nonforfeitable as of the effective time of the Sale Event, and all Awards with conditions 
and restrictions relating to the attainment of performance goals may become vested 

ACTIVE/115808348.2 

 
 
and nonforfeitable in connection with a Sale Event in the Administrator’s discretion or to the extent specified in the relevant Award Certificate. In the event 
of such termination, (i) the Company shall have the option (in its sole discretion) to make or provide for a payment, in cash or in kind, to the grantees 
holding Options and Stock Appreciation Rights, in exchange for the cancellation thereof, in an amount equal to the difference between (A) the Sale Price 
multiplied by the number of shares of Stock subject to outstanding Options and Stock Appreciation Rights (to the extent then exercisable at prices not in 
excess of the Sale Price) and (B) the aggregate exercise price of all such outstanding Options and Stock Appreciation Rights (provided that, in the case of 
an Option or Stock Appreciation Right with an exercise price equal to or greater than the Sale Price, such Option or Stock Appreciation Right shall be 
cancelled for no consideration); or (ii) each grantee shall be permitted, within a specified period of time prior to the consummation of the Sale Event as 
determined by the Administrator, to exercise all outstanding Options and Stock Appreciation Rights (to the extent then exercisable) held by such grantee. 
The Company shall also have the option (in its sole discretion) to make or provide for a payment, in cash or in kind, to the grantees holding other Awards in 
an amount equal to the Sale Price multiplied by the number of vested shares of Stock under such Awards.

SECTION 4.  ELIGIBILITY

Grantees under the Plan will be such employees, Non-Employee Directors or Consultants of the Company and its Affiliates as are selected from time to 
time by the Administrator in its sole discretion; provided that Awards may not be granted to employees, Non-Employee Directors or Consultants who are 
providing services only to any “parent” of the Company, as such term is defined in Rule 405 of the Act, unless (i) the stock underlying the Awards is 
treated as “service recipient stock” under Section 409A or (ii) the Company has determined that such Awards are exempt from or otherwise comply with 
Section 409A.

SECTION 5.  STOCK OPTIONS

(a) Award of Stock Options. The Administrator may grant Stock Options under the Plan. Any Stock Option granted under the Plan shall be in such form as 
the Administrator may from time to time approve.

Stock Options granted under the Plan may be either Incentive Stock Options or Non-Qualified Stock Options. Incentive Stock Options may be granted only 
to employees of the Company or any Subsidiary that is a “subsidiary corporation” within the meaning of Section 424(f) of the Code. To the extent that any 
Option does not qualify as an Incentive Stock Option, it shall be deemed a Non-Qualified Stock Option.

Stock Options granted pursuant to this Section 5 shall be subject to the following terms and conditions and shall contain such additional terms and 
conditions, not inconsistent with the terms of the Plan, as the Administrator shall deem desirable. If the Administrator so determines, Stock Options may be 
granted in lieu of cash compensation at the optionee’s election, subject to such terms and conditions as the Administrator may establish.

(b) Exercise Price. The exercise price per share for the Stock covered by a Stock Option granted pursuant to this Section 5 shall be determined by the 
Administrator at the time of grant but shall not be less than 100 percent of the Fair Market Value on the date of grant. In the case of an Incentive Stock 
Option that is granted to a Ten Percent Owner, the exercise price of such Incentive Stock Option shall be not less than 110 percent of the Fair Market Value 
on the grant date. Notwithstanding the foregoing, Stock Options may be granted with an exercise price per share that is less than 100 percent of the Fair 
Market Value on the date of grant (i) pursuant to a transaction described in, and in a manner consistent with, Section 424(a) of the Code, (ii) to individuals 
who are not subject to U.S. income tax on the date of grant or (iii) the Stock Option is otherwise compliant with Section 409A.

(c) Option Term. The term of each Stock Option shall be fixed by the Administrator, but no Stock Option shall be exercisable more than ten years after the 
date the Stock Option is granted. In the case of an Incentive Stock Option that is granted to a Ten Percent Owner, the term of such Stock Option shall be no 
more than five years from the date of grant.

(d) Exercisability; Rights of a Stockholder. Stock Options shall become exercisable at such time or times, whether or not in installments, as shall be 
determined by the Administrator at or after the grant date. The Administrator may at any time accelerate the exercisability of all or any portion of any Stock 
Option. An optionee shall have the rights of a stockholder only as to shares acquired upon the exercise of a Stock Option and not as to unexercised Stock 
Options.

(e) Method of Exercise. Stock Options may be exercised in whole or in part, by giving written or electronic notice of exercise to the Company, specifying 
the number of shares to be purchased. Payment of the purchase price may be made by one or more of the following methods except to the extent otherwise 
provided in the Award Certificate:

ACTIVE/115808348.2 

 
 
 
(i) In cash, by certified or bank check or other instrument acceptable to the Administrator;

(ii) Through the delivery (or attestation to the ownership following such procedures as the Company may prescribe) of shares of Stock that are not then 
subject to restrictions under any Company plan. Such surrendered shares shall be valued at Fair Market Value on the exercise date;

(iii) By the optionee delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to 
the Company cash or a check payable and acceptable to the Company for the purchase price; provided that in the event the optionee chooses to pay the 
purchase price as so provided, the optionee and the broker shall comply with such procedures and enter into such agreements of indemnity and other 
agreements as the Company shall prescribe as a condition of such payment procedure; or

(iv) With respect to Stock Options that are not Incentive Stock Options, by a “net exercise” arrangement pursuant to which the Company will reduce the 
number of shares of Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate 
exercise price.

Payment instruments will be received subject to collection. The transfer to the optionee on the records of the Company or of the transfer agent of the shares 
of Stock to be purchased pursuant to the exercise of a Stock Option will be contingent upon receipt from the optionee (or a purchaser acting in his stead in 
accordance with the provisions of the Stock Option) by the Company of the full purchase price for such shares and the fulfillment of any other 
requirements contained in the Award Certificate or applicable provisions of laws (including the satisfaction of any withholding taxes that the Company is 
obligated to withhold with respect to the optionee). In the event an optionee chooses to pay the purchase price by previously-owned shares of Stock through 
the attestation method, the number of shares of Stock transferred to the optionee upon the exercise of the Stock Option shall be net of the number of 
attested shares. In the event that the Company establishes, for itself or using the services of a third party, an automated system for the exercise of Stock 
Options, such as a system using an internet website or interactive voice response, then the paperless exercise of Stock Options may be permitted through 
the use of such an automated system.

(f) Annual Limit on Incentive Stock Options. To the extent required for “incentive stock option” treatment under Section 422 of the Code, the aggregate 
Fair Market Value (determined as of the time of grant) of the shares of Stock with respect to which Incentive Stock Options granted under this Plan and any 
other plan of the Company or its parent and subsidiary corporations become exercisable for the first time by an optionee during any calendar year shall not 
exceed $100,000. To the extent that any Stock Option exceeds this limit, it shall constitute a Non-Qualified Stock Option.

SECTION 6.  STOCK APPRECIATION RIGHTS

(a) Award of Stock Appreciation Rights. The Administrator may grant Stock Appreciation Rights under the Plan. A Stock Appreciation Right is an Award 
entitling the recipient to receive shares of Stock (or csh, to the extent explicitly provided for in the applicable Award Certificate) having a value equal to the 
excess of the Fair Market Value of a share of Stock on the date of exercise over the exercise price of the Stock Appreciation Right multiplied by the number 
of shares of Stock with respect to which the Stock Appreciation Right shall have been exercised.

(b) Exercise Price of Stock Appreciation Rights. The exercise price of a Stock Appreciation Right shall not be less than 100 percent of the Fair Market 
Value of the Stock on the date of grant.

(c) Grant and Exercise of Stock Appreciation Rights. Stock Appreciation Rights may be granted by the Administrator independently of any Stock Option 
granted pursuant to Section 5 of the Plan.

(d) Terms and Conditions of Stock Appreciation Rights. Stock Appreciation Rights shall be subject to such terms and conditions as shall be determined on 
the date of grant by the Administrator. The term of a Stock Appreciation Right may not exceed ten years. The terms and conditions of each such Award 
shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees.

SECTION 7.  RESTRICTED STOCK AWARDS

(a) Nature of Restricted Stock Awards. The Administrator may grant Restricted Stock Awards under the Plan. A Restricted Stock Award is any Award of 
Restricted Shares subject to such restrictions and conditions as the Administrator may determine at the time of 

ACTIVE/115808348.2 

 
 
 
grant. Conditions may be based on continuing employment (or other Service Relationship) and/or achievement of pre-established performance goals and 
objectives.

(b) Rights as a Stockholder. Upon the grant of the Restricted Stock Award and payment of any applicable purchase price, a grantee shall have the rights of a 
stockholder with respect to the voting of the Restricted Shares and receipt of dividends; provided that if the lapse of restrictions with respect to the 
Restricted Stock Award is tied to the attainment of performance goals, any dividends paid by the Company during the performance period shall accrue and 
shall not be paid to the grantee until and to the extent the performance goals are met with respect to the Restricted Stock Award. Unless the Administrator 
shall otherwise determine, (i) uncertificated Restricted Shares shall be accompanied by a notation on the records of the Company or the transfer agent to the 
effect that they are subject to forfeiture until such Restricted Shares are vested as provided in Section 7(d) below, and (ii) certificated Restricted Shares 
shall remain in the possession of the Company until such Restricted Shares are vested as provided in Section 7(d) below, and the grantee shall be required, 
as a condition of the grant, to deliver to the Company such instruments of transfer as the Administrator may prescribe.

(c) Restrictions. Restricted Shares may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as specifically provided 
herein or in the Restricted Stock Award Certificate. Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to 
Section 16 below, in writing after the Award is issued, if a grantee’s employment (or other Service Relationship) with the Company and its Subsidiaries 
terminates for any reason, any Restricted Shares that have not vested at the time of termination shall automatically and without any requirement of notice to 
such grantee from or other action by or on behalf of, the Company be deemed to have been reacquired by the Company at its original purchase price (if 
any) from such grantee or such grantee’s legal representative simultaneously with such termination of employment (or other Service Relationship), and 
thereafter shall cease to represent any ownership of the Company by the grantee or rights of the grantee as a stockholder. Following such deemed 
reacquisition of Restricted Shares that are represented by physical certificates, a grantee shall surrender such certificates to the Company upon request 
without consideration.

(d) Vesting of Restricted Shares. The Administrator at the time of grant shall specify the date or dates and/or the attainment of pre-established performance 
goals, objectives and other conditions on which the non-transferability of the Restricted Shares and the Company’s right of repurchase or forfeiture shall 
lapse. Subsequent to such date or dates and/or the attainment of such pre-established performance goals, objectives and other conditions, the shares on 
which all restrictions have lapsed shall no longer be Restricted Shares and shall be deemed “vested.”

SECTION 8.  RESTRICTED STOCK UNITS

(a) Nature of Restricted Stock Units. The Administrator may grant Restricted Stock Units under the Plan. A Restricted Stock Unit is an Award of stock 
units that may be settled in shares of Stock (or cash, to the extent explicitly provided for in the applicable Award Certificate) upon the satisfaction of such 
restrictions and conditions at the time of grant. Conditions may be based on continuing employment (or other Service Relationship) and/or achievement of 
pre-established performance goals and objectives. The terms and conditions of each such Award shall be determined by the Administrator, and such terms 
and conditions may differ among individual Awards and grantees. Except in the case of Restricted Stock Units with a deferred settlement date that complies 
with Section 409A, at the end of the vesting period, the Restricted Stock Units, to the extent vested, shall be settled in the form of shares of Stock. 
Restricted Stock Units with deferred settlement dates are subject to Section 409A and shall contain such additional terms and conditions as the 
Administrator shall determine in its sole discretion in order to comply with the requirements of Section 409A.

(b) Election to Receive Restricted Stock Units in Lieu of Compensation. The Administrator may, in its sole discretion, permit a grantee to elect to receive a 
portion of future cash compensation otherwise due to such grantee in the form of an award of Restricted Stock Units. Any such election shall be made in 
writing and shall be delivered to the Company no later than the date specified by the Administrator and in accordance with Section 409A and such other 
rules and procedures established by the Administrator. Any such future cash compensation that the grantee elects to defer shall be converted to a fixed 
number of Restricted Stock Units based on the Fair Market Value of Stock on the date the compensation would otherwise have been paid to the grantee if 
such payment had not been deferred as provided herein. The Administrator shall have the sole right to determine whether and under what circumstances to 
permit such elections and to impose such limitations and other terms and conditions thereon as the Administrator deems appropriate. Any Restricted Stock 
Units that are elected to be received in lieu of cash compensation shall be fully vested, unless otherwise provided in the Award Certificate.

(c) Rights as a Stockholder. A grantee shall have the rights as a stockholder only as to shares of Stock acquired by the grantee upon settlement of Restricted 
Stock Units; provided, however, that the grantee may be credited with Dividend Equivalent Rights with respect to the stock units underlying his Restricted 
Stock Units, subject to the provisions of Section 11 and such terms and conditions as the Administrator may determine.

ACTIVE/115808348.2 

 
 
(d) Termination. Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 18 below, in writing after 
the Award is issued, a grantee’s right in all Restricted Stock Units that have not vested shall automatically terminate upon the grantee’s termination of 
employment (or cessation of Service Relationship) with the Company and its Subsidiaries for any reason.

SECTION 9.  UNRESTRICTED STOCK AWARDS

Grant or Sale of Unrestricted Stock. The Administrator may grant (or sell at par value or such higher purchase price determined by the Administrator) an 
Unrestricted Stock Award under the Plan. An Unrestricted Stock Award is an Award pursuant to which the grantee may receive shares of Stock free of any 
restrictions under the Plan. Unrestricted Stock Awards may be granted in respect of past services or other valid consideration, or in lieu of cash 
compensation due to such grantee.

SECTION 10.  CASH-BASED AWARDS

Grant of Cash-Based Awards. The Administrator may grant Cash-Based Awards under the Plan. A Cash-Based Award is an Award that entitles the grantee 
to a payment in cash upon the attainment of specified performance goals. The Administrator shall determine the maximum duration of the Cash-Based 
Award, the amount of cash to which the Cash-Based Award pertains, the conditions upon which the Cash-Based Award shall become vested or payable, and 
such other provisions as the Administrator shall determine. Each Cash-Based Award shall specify a cash-denominated payment amount, formula or 
payment ranges as determined by the Administrator. Payment, if any, with respect to a Cash-Based Award shall be made in accordance with the terms of 
the Award and may be made in cash.

SECTION 11.  DIVIDEND EQUIVALENT RIGHTS

(a) Dividend Equivalent Rights. The Administrator may grant Dividend Equivalent Rights under the Plan. A Dividend Equivalent Right is an Award 
entitling the grantee to receive credits based on cash dividends that would have been paid on the shares of Stock specified in the Dividend Equivalent Right 
(or other Award to which it relates) if such shares had been issued to the grantee. A Dividend Equivalent Right may be granted hereunder to any grantee as 
a component of an award of Restricted Stock Units or as a freestanding award. The terms and conditions of Dividend Equivalent Rights shall be specified 
in the Award Certificate. Dividend equivalents credited to the holder of a Dividend Equivalent Right may be paid currently or may be deemed to be 
reinvested in additional shares of Stock, which may thereafter accrue additional equivalents. Any such reinvestment shall be at Fair Market Value on the 
date of reinvestment or such other price as may then apply under a dividend reinvestment plan sponsored by the Company, if any. Dividend Equivalent 
Rights may be settled in cash or shares of Stock or a combination thereof, in a single installment or installments. A Dividend Equivalent Right granted as a 
component of an Award of Restricted Stock Units shall provide that such Dividend Equivalent Right shall be settled only upon settlement or payment of, or 
lapse of restrictions on, such other Award, and that such Dividend Equivalent Right shall expire or be forfeited or annulled under the same conditions as 
such other Award.

(b) Termination. Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 16 below, in writing after 
the Award is issued, a grantee’s rights in all Dividend Equivalent Rights shall automatically terminate upon the grantee’s termination of employment (or 
cessation of Service Relationship) with the Company and its Subsidiaries for any reason.

SECTION 12.  TRANSFERABILITY OF AWARDS

(a) Transferability. Except as provided in Section 12(b) below, during a grantee’s lifetime, his or her Awards shall be exercisable only by the grantee, or by 
the grantee’s legal representative or guardian in the event of the grantee’s incapacity. No Awards shall be sold, assigned, transferred or otherwise 
encumbered or disposed of by a grantee other than by will or by the laws of descent and distribution or pursuant to a domestic relations order. No Awards 
shall be subject, in whole or in part, to attachment, execution, or levy of any kind, and any purported transfer in violation hereof shall be null and void.

(b) Administrator Action. Notwithstanding Section 12(a), the Administrator, in its discretion, may provide either in the Award Certificate regarding a given 
Award or by subsequent written approval that the grantee (who is an employee or director) may transfer his or her Non-Qualified Stock Options to his or 
her immediate family members, to trusts for the benefit of such family members, or to partnerships in which such family members are the only partners, 
provided that the transferee agrees in writing with the Company to be bound by all of the terms and conditions of this Plan and the applicable Award. In no 
event may an Award be transferred by a grantee for value.

ACTIVE/115808348.2 

 
 
 
 
 
(c) Family Member. For purposes of Section 12(b), “family member” shall mean a grantee’s child, stepchild, grandchild, parent, stepparent, grandparent, 
spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, including adoptive 
relationships, any person sharing the grantee’s household (other than a tenant of the grantee), a trust in which these persons (or the grantee) have more than 
50 percent of the beneficial interest, a foundation in which these persons (or the grantee) control the management of assets, and any other entity in which 
these persons (or the grantee) own more than 50 percent of the voting interests.

(d) Designation of Beneficiary. To the extent permitted by the Company, each grantee to whom an Award has been made under the Plan may designate a 
beneficiary or beneficiaries to exercise any Award or receive any payment under any Award payable on or after the grantee’s death. Any such designation 
shall be on a form provided for that purpose by the Administrator and shall not be effective until received by the Administrator. If no beneficiary has been 
designated by a deceased grantee, or if the designated beneficiaries have predeceased the grantee, the beneficiary shall be the grantee’s estate.

SECTION 13.  TAX WITHHOLDING

(a) Payment by Grantee. Each grantee shall, no later than the date as of which the value of an Award or of any Stock or other amounts received thereunder 
first becomes includable in the gross income of the grantee for Federal income tax purposes, pay to the Company, or make arrangements satisfactory to the 
Administrator regarding payment of, any Federal, state, or local taxes of any kind required by law to be withheld by the Company with respect to such 
income. The Company and its Subsidiaries shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind 
otherwise due to the grantee. The Company’s obligation to deliver evidence of book entry (or stock certificates) to any grantee is subject to and conditioned 
on tax withholding obligations being satisfied by the grantee.

(b) Payment in Stock. The Administrator may require the Company’s tax withholding obligation to be satisfied, in whole or in part, by the Company 
withholding from shares of Stock to be issued pursuant to any Award a number of shares with an aggregate Fair Market Value (as of the date the 
withholding is effected) that would satisfy the withholding amount due; provided, however, that the amount withheld does not exceed the maximum 
statutory tax rate or such lesser amount as is necessary to avoid liability accounting treatment. For purposes of share withholding, the Fair Market Value of 
withheld shares shall be determined in the same manner as the value of Stock includible in income of the grantees. The Administrator may also require the 
Company’s tax withholding obligation to be satisfied, in whole or in part, by an arrangement whereby a certain number of shares of Stock issued pursuant 
to any Award are immediately sold and proceeds from such sale are remitted to the Company in an amount that would satisfy the withholding amount due.

SECTION 14.  SECTION 409A AWARDS

Awards are intended to be exempt from Section 409A to the greatest extent possible and to otherwise comply with Section 409A. The Plan and all Awards 
shall be interpreted in accordance with such intent. To the extent that any Award is determined to constitute “nonqualified deferred compensation” within 
the meaning of Section 409A (a “409A Award”), the Award shall be subject to such additional rules and requirements as specified by the Administrator 
from time to time in order to comply with Section 409A. In this regard, if any amount under a 409A Award is payable upon a “separation from service” 
(within the meaning of Section 409A) to a grantee who is then considered a “specified employee” (within the meaning of Section 409A), then no such 
payment shall be made prior to the date that is the earlier of (i) six months and one day after the grantee’s separation from service, or (ii) the grantee’s 
death, but only to the extent such delay is necessary to prevent such payment from being subject to interest, penalties and/or additional tax imposed 
pursuant to Section 409A. Further, the settlement of any such Award may not be accelerated except to the extent permitted by Section 409A.

SECTION 15.  TERMINATION OF SERVICE RELATIONSHIP, TRANSFER, LEAVE OF ABSENCE, ETC.

(a) Termination of Service Relationship. If the grantee’s Service Relationship is with an Affiliate and such Affiliate ceases to be an Affiliate, the grantee 
shall be deemed to have terminated his or her Service Relationship for purposes of the Plan.

(b) For purposes of the Plan, the following events shall not be deemed a termination of a Service Relationship:

(i) a transfer to the employment of the Company from an Affiliate or from the Company to an Affiliate, or from one Affiliate to another; or

ACTIVE/115808348.2 

 
 
 
 
(ii) an approved leave of absence for military service or sickness, or for any other purpose approved by the Company, if the employee’s right to re-
employment is guaranteed either by a statute or by contract or under the policy pursuant to which the leave of absence was granted or if the Administrator 
otherwise so provides in writing.

SECTION 16.  AMENDMENTS AND TERMINATION

The Board may, at any time, amend or discontinue the Plan and the Administrator may, at any time, amend or cancel any outstanding Award for the 
purpose of satisfying changes in law or for any other lawful purpose, but no such action shall materially and adversely affect rights under any outstanding 
Award without the holder’s consent. Except as provided in Section 3(c) or 3(d), without prior stockholder approval, in no event may the Administrator 
exercise its discretion to reduce the exercise price of outstanding Stock Options or Stock Appreciation Rights or effect repricing through cancellation and 
re-grants or cancellation of Stock Options or Stock Appreciation Rights in exchange for cash or other Awards. To the extent required under the rules of any 
securities exchange or market system on which the Stock is listed, to the extent determined by the Administrator to be required by the Code to ensure that 
Incentive Stock Options granted under the Plan are qualified under Section 422 of the Code, Plan amendments shall be subject to approval by the 
Company’s stockholders. Nothing in this Section 16 shall limit the Administrator’s authority to take any action permitted pursuant to Section 3(c) or 3(d).

SECTION 17.  STATUS OF PLAN

With respect to the portion of any Award that has not been exercised and any payments in cash, Stock or other consideration not received by a grantee, a 
grantee shall have no rights greater than those of a general creditor of the Company unless the Administrator shall otherwise expressly determine in 
connection with any Award or Awards. In its sole discretion, the Administrator may authorize the creation of trusts or other arrangements to meet the 
Company’s obligations to deliver Stock or make payments with respect to Awards hereunder, provided that the existence of such trusts or other 
arrangements is consistent with the foregoing sentence.

SECTION 18.  GENERAL PROVISIONS

(a) No Distribution. The Administrator may require each person acquiring Stock pursuant to an Award to represent to and agree with the Company in 
writing that such person is acquiring the shares without a view to distribution thereof.

(b) Issuance. To the extent certificated, stock certificates to grantees under this Plan shall be deemed delivered for all purposes when the Company or a 
stock transfer agent of the Company shall have mailed such certificates in the United States mail, addressed to the grantee, at the grantee’s last known 
address on file with the Company. Uncertificated Stock shall be deemed delivered for all purposes when the Company or a Stock transfer agent of the 
Company shall have given to the grantee by electronic mail (with proof of receipt) or by United States mail, addressed to the grantee, at the grantee’s last 
known address on file with the Company, notice of issuance and recorded the issuance in its records (which may include electronic “book entry” records). 
Notwithstanding anything herein to the contrary, the Company shall not be required to issue or deliver any evidence of book entry or certificates evidencing 
shares of Stock pursuant to the exercise or settlement of any Award, unless and until the Administrator has determined, with advice of counsel (to the extent 
the Administrator deems such advice necessary or advisable), that the issuance and delivery is in compliance with all applicable laws, regulations of 
governmental authorities and, if applicable, the requirements of any exchange on which the shares of Stock are listed, quoted or traded. Any Stock issued 
pursuant to the Plan shall be subject to any stop-transfer orders and other restrictions as the Administrator deems necessary or advisable to comply with 
federal, state or foreign jurisdiction, securities or other laws, rules and quotation system on which the Stock is listed, quoted or traded. The Administrator 
may place legends on any Stock certificate or notations on any book entry to reference restrictions applicable to the Stock. In addition to the terms and 
conditions provided herein, the Administrator may require that an individual make such reasonable covenants, agreements, and representations as the 
Administrator, in its discretion, deems necessary or advisable in order to comply with any such laws, regulations, or requirements. The Administrator shall 
have the right to require any individual to comply with any timing or other restrictions with respect to the settlement or exercise of any Award, including a 
window-period limitation, as may be imposed in the discretion of the Administrator.

(c) Stockholder Rights. Until Stock is deemed delivered in accordance with Section 18(b), no right to vote or receive dividends or any other rights of a 
stockholder will exist with respect to shares of Stock to be issued in connection with an Award, notwithstanding the exercise of a Stock Option or any other 
action by the grantee with respect to an Award.

(d) Other Compensation Arrangements; No Employment Rights. Nothing contained in this Plan shall prevent the Board from adopting other or additional 
compensation arrangements, including trusts, and such arrangements may be either generally applicable or applicable only in specific cases. The adoption 
of this Plan and the grant of Awards do not confer upon any employee any right to continued employment with the Company or any Subsidiary.

ACTIVE/115808348.2 

 
 
 
 
(e) Trading Policy Restrictions. Option exercises and other Awards under the Plan shall be subject to the Company’s insider trading policies and 
procedures, as in effect from time to time.

(f) Clawback Policy. Awards under the Plan shall be subject to the Company’s clawback policy, as in effect from time to time.

SECTION 19.  EFFECTIVE DATE OF PLAN

This Plan, as amended and restated, shall become effective upon approval by the holders of a majority of the votes cast at a meeting of stockholders at 
which a quorum is present. No grants of Stock Options and other Awards may be made hereunder after the tenth anniversary of the Effective Date and no 
grants of Incentive Stock Options may be made hereunder after the tenth anniversary of the date the Plan, as amended and restated, is approved by the 
Board.

SECTION 20.  GOVERNING LAW

without regard to conflict of law principles.

Pursuant to the Adicet Bio, Inc. Amended and Restated 2018 Stock Option and Incentive Plan as amended through the date hereof (the “Plan”), Adicet Bio, 
Inc. (the “Company”) hereby grants to the Optionee named above an option (the “Stock Option”) to purchase on or prior to the Expiration Date specified 
above all or part of the number of shares of Common Stock, par value $0.0001 per share (the “Stock”), of the Company specified above at the Option 
Exercise Price per Share specified above subject to the terms and conditions set forth herein and in the Plan. 

1. Exercisability Schedule. No portion of this Stock Option may be exercised until such portion shall have become exercisable. Except as set forth below, 
and subject to the discretion of the Administrator (as defined in Section 2 of the Plan) to accelerate the exercisability schedule hereunder, this Stock Option 
shall be exercisable with respect to the following number of Option Shares on the dates indicated so long as the Optionee remains an employee of the 
Company or a Subsidiary on such dates:

Option Shares Exercisable*

* Max. of $100,000 per yr. 

Once exercisable, this Stock Option shall continue to be exercisable at any time or times prior to the close of business on the Expiration Date, subject to the 
provisions hereof and of the Plan. 

2. Manner of Exercise.

(a) The Optionee may exercise this Stock Option only in the following manner: from time to time on or prior to the Expiration Date of this Stock Option, 
the Optionee may give written notice to the Administrator of his or her election to purchase some or all of the Option Shares purchasable at the time of 
such notice. This notice shall specify the number of Option Shares to be purchased. 

Payment of the purchase price for the Option Shares may be made by one or more of the following methods: (i) in cash, by certified or bank check or other 
instrument acceptable to the Administrator; (ii) through the delivery (or attestation to the ownership) of shares of Stock that have been purchased by the 
Optionee on the open market or that are beneficially owned by the Optionee and are not then subject to any restrictions under any Company plan and that 
otherwise satisfy any holding periods as may be required by the Administrator; or (iii) by the Optionee delivering to the Company a properly executed 
exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the 
Company to pay the option purchase price, provided that in the event the Optionee chooses to pay the option purchase price as so provided, the Optionee 
and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Administrator shall prescribe as 
a condition of such payment procedure; or (iv) a combination of (i), (ii) and (iii) above. Payment instruments will be received subject to collection.

The transfer to the Optionee on the records of the Company or of the transfer agent of the Option Shares will be contingent upon (i) the Company’s receipt 
from the Optionee of the full purchase price for the Option Shares, as set forth above, (ii) the fulfillment of any other requirements contained herein or in 
the Plan or in any other agreement or provision of laws, and (iii) the receipt by the Company of any agreement, statement or other evidence that the 
Company may require to satisfy itself that the issuance of Stock to be purchased pursuant to the exercise of Stock Options under the Plan and any 
subsequent resale of the shares of Stock will be in compliance with applicable laws and regulations. In the event the Optionee chooses to pay the purchase 
price by previously-owned shares of Stock through the attestation method, the number of shares of Stock transferred to the Optionee upon the exercise of 
the Stock Option shall be net of the Shares attested to. 

(b) The shares of Stock purchased upon exercise of this Stock Option shall be transferred to the Optionee on the records of the Company or of the transfer 
agent upon compliance to the satisfaction of the Administrator with all requirements under applicable laws or regulations in connection with such transfer 
and with the requirements hereof and of the Plan. The determination of the Administrator as to such compliance shall be final and binding on the Optionee. 
The Optionee shall not be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Stock subject to this Stock 
Option unless and until this Stock Option shall have been exercised pursuant to the terms hereof, the Company or the transfer agent shall have transferred 
the shares to the Optionee, and the Optionee’s name shall have been entered as the stockholder of record on the books of the Company. Thereupon, the 
Optionee shall have full voting, dividend and other ownership rights with respect to such shares of Stock. 

(c) The minimum number of shares with respect to which this Stock Option may be exercised at any one time shall be 100 shares, unless the number of 
shares with respect to which this Stock Option is being exercised is the total number of shares subject to exercise under this Stock Option at the time. 

(d) Notwithstanding any other provision hereof or of the Plan, no portion of this Stock Option shall be exercisable after the Expiration Date hereof. 

3. Termination of Employment. If the Optionee’s employment by the Company or a Subsidiary (as defined in the Plan) is terminated, the period within 
which to exercise the Stock Option may be subject to earlier termination as set forth below. 

(a) Termination Due to Death. If the Optionee’s employment terminates by reason of the Optionee’s death, any portion of this Stock Option outstanding on 
such date, to the extent exercisable on the date of death, may thereafter be exercised by the Optionee’s legal representative or legatee for a period of 12 
months from the date of death or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of death shall 
terminate immediately and be of no further force or effect. 

(b) Termination Due to Disability. If the Optionee’s employment terminates by reason of the Optionee’s disability (as determined by the Administrator), 
any portion of this Stock Option outstanding on such date, to the extent exercisable on the date of such termination of employment, may thereafter be 
exercised by the Optionee for a period of 12 months from the date of disability or until the Expiration Date, if earlier. Any portion of this Stock Option that 
is not exercisable on the date of disability shall terminate immediately and be of no further force or effect. 

(c) Termination for Cause. If the Optionee’s employment terminates for Cause, any portion of this Stock Option outstanding on such date shall terminate 
immediately and be of no further force and effect. For purposes hereof, “Cause” shall mean, unless otherwise provided in an employment agreement 
between the Company and the Optionee, a determination by the Administrator that the Optionee shall be dismissed as a result of (i) any material breach by 
the Optionee of any agreement between the Optionee and the Company; (ii) the conviction of, indictment for or plea of nolo contendere by the Optionee to 
a felony or a crime involving moral turpitude; or (iii) any material misconduct or willful and deliberate non-performance (other than by reason of disability) 
by the Optionee of the Optionee’s duties to the Company. 

(d) Other Termination. If the Optionee’s employment terminates for any reason other than the Optionee’s death, the Optionee’s disability, or Cause, and 
unless otherwise determined by the Administrator, any portion of this Stock Option outstanding on such date may be exercised, to the extent exercisable on 
the date of termination, for a period of three months from the date of termination or until the Expiration Date, if earlier. Any portion of this Stock Option 
that is not exercisable on the date of termination shall terminate immediately and be of no further force or effect.  The Administrator’s determination of the 
reason for termination of the Optionee’s employment shall be conclusive and binding on the Optionee and his or her representatives or legatees. 

4. Incorporation of Plan. Notwithstanding anything herein to the contrary, this Stock Option shall be subject to and governed by all the terms and conditions 
of the Plan, including the powers of the Administrator set forth in Section 2(b) of the Plan. Capitalized terms in this Agreement shall have the meaning 
specified in the Plan, unless a different meaning is specified herein. 

ACTIVE/115808348.2 

 
  
5. Transferability. This Agreement is personal to the Optionee, is non-assignable and is not transferable in any manner, by operation of law or otherwise, 
other than by will or the laws of descent and distribution. This Stock Option is exercisable, during the Optionee’s lifetime, only by the Optionee, and 
thereafter, only by the Optionee’s legal representative or legatee. 

6. Status of the Stock Option. This Stock Option is intended to qualify as an “incentive stock option” under Section 422 of the Internal Revenue Code of 
1986, as amended (the “Code”), but the Company does not represent or warrant that this Stock Option qualifies as such. The Optionee should consult with 
his or her own tax advisors regarding the tax effects of this Stock Option and the requirements necessary to obtain favorable income tax treatment under 
Section 422 of the Code, including, but not limited to, holding period requirements. To the extent any portion of this Stock Option does not so qualify as an 
“incentive stock option,” such portion shall be deemed to be a non-qualified stock option. If the Optionee intends to dispose or does dispose (whether by 
sale, gift, transfer or otherwise) of any Option Shares within the one-year period beginning on the date after the transfer of such shares to him or her, or 
within the two-year period beginning on the day after the grant of this Stock Option, he or she will so notify the Company within 30 days after such 
disposition. 

7. Tax Withholding. The Optionee shall, not later than the date as of which the exercise of this Stock Option becomes a taxable event for Federal income 
tax purposes, pay to the Company or make arrangements satisfactory to the Administrator for payment of any Federal, state, and local taxes required by law 
to be withheld on account of such taxable event. The Company shall have the authority to cause the required tax withholding obligation to be satisfied, in 
whole or in part, by withholding from shares of Stock to be issued to the Optionee a number of shares of Stock with an aggregate Fair Market Value that 
would satisfy the withholding amount due; provided, however, that the amount withheld does not exceed the maximum statutory tax rate or such lesser 
amount as is necessary to avoid adverse accounting treatment or as determined by the Administrator. 

8. No Obligation to Continue Employment. Neither the Company nor any Subsidiary is obligated by or as a result of the Plan or this Agreement to continue 
the Optionee in employment and neither the Plan nor this Agreement shall interfere in any way with the right of the Company or any Subsidiary to 
terminate the employment of the Optionee at any time. 

9. Integration. This Agreement constitutes the entire agreement between the parties with respect to this Stock Option and supersedes all prior agreements 
and discussions between the parties concerning such subject matter. 

10. Data Privacy Consent. In order to administer the Plan and this Agreement and to implement or structure future equity grants, the Company, its 
subsidiaries and affiliates and certain agents thereof (together, the “Relevant Companies”) may process any and all personal or professional data, including 
but not limited to Social Security or other identification number, home address and telephone number, date of birth and other information that is necessary 
or desirable for the administration of the Plan and/or this Agreement (the “Relevant Information”). By entering into this Agreement, the Optionee (i) 
authorizes the Company to collect, process, register and transfer to the Relevant Companies all Relevant Information; (ii) waives any privacy rights the 
Optionee may have with respect to the Relevant Information; (iii) authorizes the Relevant Companies to store and transmit such information in electronic 
form; and (iv) authorizes the transfer of the Relevant Information to any jurisdiction in which the Relevant Companies consider appropriate. The Optionee 
shall have access to, and the right to change, the Relevant Information. Relevant Information will only be used in accordance with applicable law. 

11. Notices. Notices hereunder shall be mailed or delivered to the Company at its principal place of business and shall be mailed or delivered to the 
Optionee at the address on file with the Company or, in either case, at such other address as one party may subsequently furnish to the other party in 
writing.

Inc. (the “Company”) hereby grants to the Optionee named above, who is a Director of the Company but is not an employee of the Company, an option (the

share (the “Stock”), of the Company specified above at the Option Exercise Price per Share specified above subject to the terms and conditions set forth 
herein and in the Plan. This Stock Option is not intended to be an “incentive stock option” under Section 422 of the Internal Revenue Code of 1986, as 
amended. 

1. Exercisability Schedule. No portion of this Stock Option may be exercised until such portion shall have become exercisable. Except as set forth below, 
and subject to the discretion of the Administrator (as defined in Section 2 of the Plan) to accelerate the exercisability schedule hereunder, this Stock Option

Once exercisable, this Stock Option shall continue to be exercisable at any time or times prior to the close of business on the Expiration Date, subject to the 
provisions hereof and of the Plan. 

2. Manner of Exercise.

(a) The Optionee may exercise this Stock Option only in the following manner: from time to time on or prior to the Expiration Date of this Stock Option, 
the Optionee may give written notice to the Administrator of his or her election to purchase some or all of the Option Shares purchasable at the time of 
such notice. This notice shall specify the number of Option Shares to be purchased. 

Payment of the purchase price for the Option Shares may be made by one or more of the following methods: (i) in cash, by certified or bank check or other 
instrument acceptable to the Administrator; (ii) through the delivery (or attestation to the ownership) of shares of Stock that have been purchased by the 
Optionee on the open market or that are beneficially owned by the Optionee and are not then subject to any restrictions under any Company plan and that 
otherwise satisfy any holding periods as may be required by the Administrator; (iii) by the Optionee delivering to the Company a properly executed 
exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the 
Company to pay the option purchase price, provided that in the event the Optionee chooses to pay the option purchase price as so provided, the Optionee 
and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Administrator shall prescribe as 
a condition of such payment procedure; (iv) by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Stock 
issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price; or (v) a 
combination of (i), (ii), (iii) and (iv) above. Payment instruments will be received subject to collection. 

The transfer to the Optionee on the records of the Company or of the transfer agent of the Option Shares will be contingent upon (i) the Company’s receipt 
from the Optionee of the full purchase price for the Option Shares, as set forth above, (ii) the fulfillment of any other requirements contained herein or in 
the Plan or in any other agreement or provision of laws, and (iii) the receipt by the Company of any agreement, statement or other evidence that the

The Optionee shall not be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Stock subject to this Stock 
Option unless and until this Stock Option shall have been exercised pursuant to the terms hereof, the Company or the transfer agent shall have transferred 
the shares to the Optionee, and the Optionee’s name shall have been entered as the stockholder of record on the books of the Company. Thereupon, the 
Optionee shall have full voting, dividend and other ownership rights with respect to such shares of Stock. 

(c) The minimum number of shares with respect to which this Stock Option may be exercised at any one time shall be 100 shares, unless the number of 
shares with respect to which this Stock Option is being exercised is the total number of shares subject to exercise under this Stock Option at the time. 

(d) Notwithstanding any other provision hereof or of the Plan, no portion of this Stock Option shall be exercisable after the Expiration Date hereof. 

3. Termination as Director. If the Optionee ceases to be a Director of the Company, the period within which to exercise the Stock Option may be subject to 
earlier termination as set forth below. 

(a) Termination Due to Death. If the Optionee’s service as a Director terminates by reason of the Optionee’s death, any portion of this Stock Option 
outstanding on such date, to the extent exercisable on the date of death, may thereafter be exercised by the Optionee’s legal representative or legatee for a 
period of 12 months from the date of death or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of 
death shall terminate immediately and be of no further force or effect. 

(b) Other Termination. If the Optionee ceases to be a Director for any reason other than the Optionee’s death, any portion of this Stock Option outstanding

Optionee ceased to be a Director or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date the Optionee 
ceases to be a Director shall terminate immediately and be of no further force or effect.

thereafter, only by the Optionee’s legal representative or legatee. 

6. No Obligation to Continue as a Director. Neither the Plan nor this Stock Option confers upon the Optionee any rights with respect to continuance as a 
Director. 

7. Integration. This Agreement constitutes the entire agreement between the parties with respect to this Stock Option and supersedes all prior agreements 
and discussions between the parties concerning such subject matter.

Inc. (the “Company”) hereby grants to the Optionee named above an option (the “Stock Option”) to purchase on or prior to the Expiration Date specified 
above all or part of the number of shares of Common Stock, par value $0.0001 per share (the “Stock”) of the Company specified above at the Option 
Exercise Price per Share specified above subject to the terms and conditions set forth herein and in the Plan. This Stock Option is not intended to be an 
“incentive stock option” under Section 422 of the Internal Revenue Code of 1986, as amended. 

1. Exercisability Schedule. No portion of this Stock Option may be exercised until such portion shall have become exercisable. Except as set forth below, 
and subject to the discretion of the Administrator (as defined in Section 2 of the Plan) to accelerate the exercisability schedule hereunder, this Stock Option

( %)  

Once exercisable, this Stock Option shall continue to be exercisable at any time or times prior to the close of business on the Expiration Date, subject to the 
provisions hereof and of the Plan. 

2. Manner of Exercise.

(a) The Optionee may exercise this Stock Option only in the following manner: from time to time on or prior to the Expiration Date of this Stock Option, 
the Optionee may give written notice to the Administrator of his or her election to purchase some or all of the Option Shares purchasable at the time of 
such notice. This notice shall specify the number of Option Shares to be purchased. 

Payment of the purchase price for the Option Shares may be made by one or more of the following methods: (i) in cash, by certified or bank check or other 
instrument acceptable to the Administrator; (ii) through the delivery (or attestation to the ownership) of shares of Stock that have been purchased by the 
Optionee on the open market or that are beneficially owned by the Optionee and are not then subject to any restrictions under any Company plan and that 
otherwise satisfy any holding periods as may be required by the Administrator; (iii) by the Optionee delivering to the Company a properly executed 
exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the 
Company to pay the option purchase price, provided that in the event the Optionee chooses to pay the option purchase price as so provided, the Optionee 
and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Administrator shall prescribe as 
a condition of such payment procedure; (iv) by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Stock 
issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price; or (v) a 
combination of (i), (ii), (iii) and (iv) above. Payment instruments will be received subject to collection. 

The transfer to the Optionee on the records of the Company or of the transfer agent of the Option Shares will be contingent upon (i) the Company’s receipt 
from the Optionee of the full purchase price for the Option Shares, as set forth above, (ii) the fulfillment of any other requirements contained herein or in 
the Plan or in any other agreement or provision of laws, and (iii) the receipt by the Company of any agreement, statement or other evidence that the 
Company may require to satisfy itself that the issuance of Stock to be purchased pursuant to the exercise of Stock Options under the Plan and any 
subsequent resale of the shares of Stock will be in

compliance with applicable laws and regulations. In the event the Optionee chooses to pay the purchase price by previously-owned shares of Stock through 
the attestation method, the number of shares of Stock transferred to the Optionee upon the exercise of the Stock Option shall be net of the Shares attested 
to. 

(b) The shares of Stock purchased upon exercise of this Stock Option shall be transferred to the Optionee on the records of the Company or of the transfer 
agent upon compliance to the satisfaction of the Administrator with all requirements under applicable laws or regulations in connection with such transfer 
and with the requirements hereof and of the Plan. The determination of the Administrator as to such compliance shall be final and binding on the Optionee. 
The Optionee shall not be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Stock subject to this Stock 
Option unless and until this Stock Option shall have been exercised pursuant to the terms hereof, the Company or the transfer agent shall have transferred 
the shares to the Optionee, and the Optionee’s name shall have been entered as the stockholder of record on the books of the Company. Thereupon, the 
Optionee shall have full voting, dividend and other ownership rights with respect to such shares of Stock. 

(c) The minimum number of shares with respect to which this Stock Option may be exercised at any one time shall be 100 shares, unless the number of 
shares with respect to which this Stock Option is being exercised is the total number of shares subject to exercise under this Stock Option at the time. 

(d) Notwithstanding any other provision hereof or of the Plan, no portion of this Stock Option shall be exercisable after the Expiration Date hereof. 

3. Termination of Employment. If the Optionee’s employment by the Company or a Subsidiary (as defined in the Plan) is terminated, the period within 
which to exercise the Stock Option may be subject to earlier termination as set forth below. 

(a) Termination Due to Death. If the Optionee’s employment terminates by reason of the Optionee’s death, any portion of this Stock Option outstanding on 
such date, to the extent exercisable on the date of death, may thereafter be exercised by the Optionee’s legal representative or legatee for a period of 12 
months from the date of death or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of death shall 
terminate immediately and be of no further force or effect. 

(b) Termination Due to Disability. If the Optionee’s employment terminates by reason of the Optionee’s disability (as determined by the Administrator), 
any portion of this Stock Option outstanding on such date, to the extent exercisable on the date of such termination of employment, may thereafter be 
exercised by the Optionee for a period of 12 months from the date of disability or until the Expiration Date, if earlier. Any portion of this Stock Option that 
is not exercisable on the date of disability shall terminate immediately and be of no further force or effect. 

(c) Termination for Cause. If the Optionee’s employment terminates for Cause, any portion of this Stock Option outstanding on such date shall terminate 
immediately and be of no further force and effect. For purposes hereof, “Cause” shall mean, unless otherwise provided in an employment agreement 
between the Company and the Optionee, a determination by the Administrator that the Optionee shall be dismissed as a result of (i) any material breach by 
the Optionee of any agreement between the Optionee and the Company; (ii) the conviction of, indictment for or plea of nolo contendere by the Optionee to 
a felony or a crime involving moral turpitude; or (iii) any material misconduct or willful and deliberate non-performance (other than by reason of disability) 
by the Optionee of the Optionee’s duties to the Company. 

(d) Other Termination. If the Optionee’s employment terminates for any reason other than the Optionee’s death, the Optionee’s disability or Cause, and 
unless otherwise determined by the Administrator, any portion of this Stock Option outstanding on such date may be exercised, to the extent exercisable on 
the date of termination, for a period of three months from the date of termination or until the Expiration Date, if earlier. Any portion of this Stock Option 
that is not exercisable on the date of termination shall terminate immediately and be of no further force or effect. 

The Administrator’s determination of the reason for termination of the Optionee’s employment shall be conclusive and binding on the Optionee and his or 
her representatives or legatees. 

4. Incorporation of Plan. Notwithstanding anything herein to the contrary, this Stock Option shall be subject to and governed by all the terms and conditions 
of the Plan, including the powers of the Administrator set forth in Section 2(b) of the Plan. Capitalized terms in this Agreement shall have the meaning 
specified in the Plan, unless a different meaning is specified herein. 

5. Transferability. This Agreement is personal to the Optionee, is non-assignable and is not transferable in any manner, by operation of law or otherwise, 
other than by will or the laws of descent and distribution. This Stock Option is exercisable, during the Optionee’s lifetime, only by the Optionee, and 
thereafter, only by the Optionee’s legal representative or legatee. 

ACTIVE/115808348.2 

 
  
  
6. Tax Withholding. The Optionee shall, not later than the date as of which the exercise of this Stock Option becomes a taxable event for Federal income 
tax purposes, pay to the Company or make arrangements satisfactory to the Administrator for payment of any Federal, state, and local taxes required by law 
to be withheld on account of such taxable event. The Company shall have the authority to cause the required tax withholding obligation to be satisfied, in 
whole or in part, by withholding from shares of Stock to be issued to the Optionee a number of shares of Stock with an aggregate Fair Market Value that 
would satisfy the withholding amount due; provided, however, that the amount withheld does not exceed the maximum statutory tax rate or such lesser 
amount as is necessary to avoid adverse accounting treatment or as determined by the Administrator. 

7. No Obligation to Continue Employment. Neither the Company nor any Subsidiary is obligated by or as a result of the Plan or this Agreement to continue 
the Optionee in employment and neither the Plan nor this Agreement shall interfere in any way with the right of the Company or any Subsidiary to 
terminate the employment of the Optionee at any time. 

8. Integration. This Agreement constitutes the entire agreement between the parties with respect to this Stock Option and supersedes all prior agreements 
and discussions between the parties concerning such subject matter. 

9. Data Privacy Consent. In order to administer the Plan and this Agreement and to implement or structure future equity grants, the Company, its 
subsidiaries and affiliates and certain agents thereof (together, the “Relevant Companies”) may process any and all personal or professional data, including 
but not limited to Social Security or other identification number, home address and telephone number, date of birth and other information that is necessary 
or desirable for the administration of the Plan and/or this Agreement (the “Relevant Information”). By entering into this Agreement, the Optionee (i) 
authorizes the Company to collect, process, register and transfer to the Relevant Companies all Relevant Information; (ii) waives any privacy rights the 
Optionee may have with respect to the Relevant Information; (iii) authorizes the Relevant Companies to store and transmit such information in electronic 
form; and (iv) authorizes the transfer of the Relevant Information to any jurisdiction in which the Relevant 

Companies consider appropriate. The Optionee shall have access to, and the right to change, the Relevant Information. Relevant Information will only be 
used in accordance with applicable law. 

10. Notices. Notices hereunder shall be mailed or delivered to the Company at its principal place of business and shall be mailed or delivered to the 
Optionee at the address on file with the Company or, in either case, at such other address as one party may subsequently furnish to the other party in 
writing.

representations of the Company or any of its agents with regard to such election. 

9. No Obligation to Continue Employment. Neither the Company nor any Subsidiary is obligated by or as a result of the Plan or this Agreement to continue 
the Grantee in employment and neither the Plan nor this Agreement shall interfere in any way with the right of the Company or any Subsidiary to terminate 
the employment of the Grantee at any time. 

10. Integration. This Agreement constitutes the entire agreement between the parties with respect to this Award and supersedes all prior agreements and 
discussions between the parties concerning such subject matter. 

11. Data Privacy Consent. In order to administer the Plan and this Agreement and to implement or structure future equity grants, the Company, its 
subsidiaries and affiliates and certain agents thereof (together, the “Relevant Companies”) may process any and all personal or professional data, including

AMENDED AND RESTATED 2018 EMPLOYEE STOCK PURCHASE PLAN

Exhibit 10.14

The purpose of the Adicet Bio, Inc. Amended and Restated 2018 Employee Stock Purchase Plan (“the Plan”) is to provide eligible employees of Adicet 
Bio, Inc. (the “Company”) and each Designated Subsidiary (as defined in Section 11) with opportunities to purchase shares of the Company’s common 
stock, par value $0.0001 per share (the “Common Stock”). 524,775 shares of Common Stock have been approved and reserved for this purpose, plus on 
January 1, 2022, and each January 1 thereafter through January 1, 2031, the number of shares of Common Stock reserved and available for issuance under 
the Plan shall be cumulatively increased by the least of (i) 1,262,560 shares of Common Stock, (ii) one percent (1%) of the number of shares of Common 
Stock issued and outstanding on the immediately preceding December 31st, or (iii) such lesser number of shares of Common Stock as determined by the 
Administrator. The Plan is intended to constitute an “employee stock purchase plan” within the meaning of Section 423(b) of the Internal Revenue Code of 
1986, as amended (the “Code”), and shall be interpreted in accordance with that intent.

1. Administration. The Plan will be administered by the person or persons (the “Administrator”) appointed by the Company’s Board of Directors (the 
“Board”) for such purpose. The Administrator has authority at any time to: (i) adopt, alter and repeal such rules, guidelines and practices for the 
administration of the Plan and for its own acts and proceedings as it shall deem advisable; (ii) interpret the terms and provisions of the Plan; (iii) make all 
determinations it deems advisable for the administration of the Plan; (iv) decide all disputes arising in connection with the Plan; and (v) otherwise supervise 
the administration of the Plan. All interpretations and decisions of the Administrator shall be binding on all persons, including the Company and the 
Participants. No member of the Board or individual exercising administrative authority with respect to the Plan shall be liable for any action or 
determination made in good faith with respect to the Plan or any option granted hereunder.

2. Offerings. The Company will make one or more offerings to eligible employees to purchase Common Stock under the Plan (“Offerings”). Unless 
otherwise determined by the Administrator, an Offering will begin on the first business day occurring on or after each January 1 and July 1 and will end on 
the last business day occurring on or before the following June 30 and December 31, respectively. The Administrator may, in its discretion, designate a 
different period for any Offering, provided that no Offering shall exceed one year in duration or overlap any other Offering.

3. Eligibility. All individuals classified as employees on the payroll records of the Company and each Designated Subsidiary are eligible to participate in 
any one or more of the Offerings under the Plan, provided that as of the first day of the applicable Offering (the “Offering Date”) they are customarily 
employed by the Company or a Designated Subsidiary for more than 20 hours a week and have completed at least three months of employment. 
Notwithstanding any other provision herein, individuals who are not contemporaneously classified as employees of the Company or a Designated 
Subsidiary for purposes of the Company’s or applicable Designated Subsidiary’s payroll system are not considered to be eligible employees of the 
Company or any Designated Subsidiary and shall not be eligible to participate in the Plan. In the event any such individuals are reclassified as employees 
of the Company or a Designated Subsidiary for any purpose, including, without limitation, common law or statutory employees, by any action of any third 
party, including, without limitation, any government agency, or as a result of any private lawsuit, action or administrative proceeding, such individuals 
shall, notwithstanding such reclassification, remain ineligible for participation. Notwithstanding the foregoing, the exclusive means for individuals who are 
not contemporaneously classified as employees of the Company or a Designated Subsidiary on the Company’s or Designated Subsidiary’s payroll system 
to become eligible to participate in this Plan is through an amendment to this Plan, duly executed by the Company, which specifically renders such 
individuals eligible to participate herein.

4. Participation.

(a) Participants. An eligible employee who is not a Participant in any prior Offering may participate in a subsequent Offering by submitting an enrollment 
form to his or her appropriate payroll location at least 15 business days before the Offering Date (or by such other deadline as shall be established by the 
Administrator for the Offering).

(b) Enrollment. The enrollment form will (a) state a whole percentage to be deducted from an eligible employee’s Compensation (as defined in Section 11) 
per pay period, (b) authorize the purchase of Common Stock in each Offering in accordance with the terms of the Plan and (c) specify the exact name or 
names in which shares of Common Stock purchased for such individual are to be issued pursuant to Section 10. An employee who does not enroll in 
accordance with these procedures will be deemed to have waived the right to participate. Unless a Participant files a new enrollment form or withdraws 
from the Plan, such Participant’s deductions and purchases will continue at the same percentage of Compensation for future Offerings, provided he or she 
remains eligible.

ACTIVE/115808347.2 

 
(c) Notwithstanding the foregoing, participation in the Plan will neither be permitted nor be denied contrary to the requirements of the Code.

5. Employee Contributions. Each eligible employee may authorize payroll deductions up to a maximum of fifteen percent of such employee’s 
Compensation for each pay period. The Company will maintain book accounts showing the amount of payroll deductions made by each Participant for 
each Offering. No interest will accrue or be paid on payroll deductions.

6. Deduction Changes. Except as may be determined by the Administrator in advance of an Offering, a Participant may not increase or decrease his or her 
payroll deduction during any Offering, but may increase or decrease his or her payroll deduction with respect to the next Offering (subject to the limitations 
of Section 5) by filing a new enrollment form at least 15 business days before the next Offering Date (or by such other deadline as shall be established by 
the Administrator for the Offering). The Administrator may, in advance of any Offering, establish rules permitting a Participant to increase, decrease or 
terminate his or her payroll deduction during an Offering.

7. Withdrawal. A Participant may withdraw from participation in the Plan by delivering a written notice of withdrawal to his or her appropriate payroll 
location. The Participant’s withdrawal will be effective as of the next business day. Following a Participant’s withdrawal, the Company will promptly 
refund such individual’s entire account balance under the Plan to him or her (after payment for any Common Stock purchased before the effective date of 
withdrawal). Partial withdrawals are not permitted. Such an employee may not begin participation again during the remainder of the Offering, but may 
enroll in a subsequent Offering in accordance with Section 4.

8. Grant of Options. On each Offering Date, the Company will grant to each eligible employee who is then a Participant in the Plan an option (“Option”) to 
purchase on the last day of such Offering (the “Exercise Date”), at the Option Price hereinafter provided for, the lowest of (a) a number of shares of 
Common Stock determined by dividing such Participant’s accumulated payroll deductions on such Exercise Date by the lower of (i) 85 percent of the Fair 
Market Value of the Common Stock on the Offering Date, or (ii) 85 percent of the Fair Market Value of the Common Stock on the Exercise Date, (b) a 
number of shares determined by dividing $25,000 by the Fair Market of the Common Stock on the Offering Date of such Offering ; or (c) such other lesser 
maximum number of shares as shall have been established by the Administrator in advance of the Offering; provided, however, that such Option shall be 
subject to the limitations set forth below. Each Participant’s Option shall be exercisable only to the extent of such Participant’s accumulated payroll 
deductions on the Exercise Date. The purchase price for each share purchased under each Option (the “Option Price”) will be 85 percent of the Fair Market 
Value of the Common Stock on the Offering Date or the Exercise Date, whichever is less.

Notwithstanding the foregoing, no Participant may be granted an option hereunder if such Participant, immediately after the option was granted, would be 
treated as owning stock possessing 5 percent or more of the total combined voting power or value of all classes of stock of the Company or any Parent or 
Subsidiary (as defined in Section 11). For purposes of the preceding sentence, the attribution rules of Section 424(d) of the Code shall apply in determining 
the stock ownership of a Participant, and all stock which the Participant has a contractual right to purchase shall be treated as stock owned by the 
Participant. In addition, no Participant may be granted an Option which permits his or her rights to purchase stock under the Plan, and any other employee 
stock purchase plan of the Company and its Parents and Subsidiaries, to accrue at a rate which exceeds $25,000 of the fair market value of such stock 
(determined on the option grant date or dates) for each calendar year in which the Option is outstanding at any time. The purpose of the limitation in the 
preceding sentence is to comply with Section 423(b)(8) of the Code and shall be applied taking Options into account in the order in which they were 
granted.

9. Exercise of Option and Purchase of Shares. Each employee who continues to be a Participant in the Plan on the Exercise Date shall be deemed to have 
exercised his or her Option on such date and shall acquire from the Company such number of whole shares of Common Stock reserved for the purpose of 
the Plan as his or her accumulated payroll deductions on such date will purchase at the Option Price, subject to any other limitations contained in the Plan. 
Any amount remaining in a Participant’s account at the end of an Offering solely by reason of the inability to purchase a fractional share will be carried 
forward to the next Offering; any other balance remaining in a Participant’s account at the end of an Offering will be refunded to the Participant promptly.

10. Issuance of Certificates. Certificates representing shares of Common Stock purchased under the Plan may be issued only in the name of the employee, 
in the name of the employee and another person of legal age as joint tenants with rights of survivorship, or in the name of a broker authorized by the 
employee to be his, her or their, nominee for such purpose.

11. Definitions.

The term “Compensation” means the amount of base pay, prior to salary reduction pursuant to Sections 125, 132(f) or 401(k) of the Code, but excluding 
overtime, commissions, incentive or bonus awards, allowances and reimbursements for expenses such as relocation allowances or travel expenses, income 
or gains on the exercise of Company stock options, and similar items

ACTIVE/115808347.2 

 
The term “Designated Subsidiary” means any present or future Subsidiary (as defined below) that has been designated by the Board to participate in the 
Plan. The Board may so designate any Subsidiary, or revoke any such designation, at any time and from time to time, either before or after the Plan is 
approved by the stockholders. The current list of Designated Companies is attached hereto as Appendix A.

The term “Fair Market Value of the Common Stock” on any given date means the fair market value of the Common Stock determined in good faith by the 
Administrator; provided, however, that if the Common Stock is admitted to quotation on the National Association of Securities Dealers Automated 
Quotation System (“Nasdaq”), Nasdaq Global Market or another national securities exchange, the determination shall be made by reference to the closing 
price on such date. If there is no closing price for such date, the determination shall be made by reference to the last date preceding such date for which 
there is a closing price.

The term “Initial Public Offering” means the first underwritten, firm commitment public offering pursuant to an effective registration statement under the 
Securities Act of 1933, as amended, covering the offer and sale by the Company of its Common Stock.

The term “Parent” means a “parent corporation” with respect to the Company, as defined in Section 424(e) of the Code.

The term “Participant” means an individual who is eligible as determined in Section 3 and who has complied with the provisions of Section 4.

The term “Subsidiary” means a “subsidiary corporation” with respect to the Company, as defined in Section 424(f) of the Code.

12. Rights on Termination of Employment. If a Participant’s employment terminates for any reason before the Exercise Date for any Offering, no payroll 
deduction will be taken from any pay due and owing to the Participant and the balance in the Participant’s account will be paid to such Participant or, in the 
case of such Participant’s death, to his or her designated beneficiary as if such Participant had withdrawn from the Plan under Section 7. An employee will 
be deemed to have terminated employment, for this purpose, if the corporation that employs him or her, having been a Designated Subsidiary, ceases to be 
a Subsidiary, or if the employee is transferred to any corporation other than the Company or a Designated Subsidiary. An employee will not be deemed to 
have terminated employment for this purpose, if the employee is on an approved leave of absence for military service or sickness or for any other purpose 
approved by the Company, if the employee’s right to reemployment is guaranteed either by a statute or by contract or under the policy pursuant to which 
the leave of absence was granted or if the Administrator otherwise provides in writing.

13. Special Rules. Notwithstanding anything herein to the contrary, the Administrator may adopt special rules applicable to the employees of a particular 
Designated Subsidiary, whenever the Administrator determines that such rules are necessary or appropriate for the implementation of the Plan in a 
jurisdiction where such Designated Subsidiary has employees; provided that such rules are consistent with the requirements of Section 423(b) of the Code. 
Any special rules established pursuant to this Section 13 shall, to the extent possible, result in the employees subject to such rules having substantially the 
same rights as other Participants in the Plan.

14. Optionees Not Stockholders. Neither the granting of an Option to a Participant nor the deductions from his or her pay shall constitute such Participant a 
holder of the shares of Common Stock covered by an Option under the Plan until such shares have been purchased by and issued to him or her.

15. Rights Not Transferable. Rights under the Plan are not transferable by a Participant other than by will or the laws of descent and distribution, and are 
exercisable during the Participant’s lifetime only by the Participant.

16. Application of Funds. All funds received or held by the Company under the Plan may be combined with other corporate funds and may be used for any 
corporate purpose.

17. Adjustment in Case of Changes Affecting Common Stock. In the event of a subdivision of outstanding shares of Common Stock, the payment of a 
dividend in Common Stock or any other change affecting the Common Stock, the number of shares approved for the Plan and the share limitation set forth 
in Section 8 shall be equitably or proportionately adjusted to give proper effect to such event.

18. Amendment of the Plan. The Board may at any time and from time to time amend the Plan in any respect, except that without the approval within 12 
months of such Board action by the stockholders, no amendment shall be made increasing the number of shares approved for the Plan or making any other 
change that would require stockholder approval in order for the Plan, as amended, to qualify as an “employee stock purchase plan” under Section 423(b) of 
the Code.

19. Insufficient Shares. If the total number of shares of Common Stock that would otherwise be purchased on any Exercise Date plus the number of shares 
purchased under previous Offerings under the Plan exceeds the maximum number of shares issuable under the 

ACTIVE/115808347.2 

 
Plan, the shares then available shall be apportioned among Participants in proportion to the amount of payroll deductions accumulated on behalf of each 
Participant that would otherwise be used to purchase Common Stock on such Exercise Date.

20. Termination of the Plan. The Plan may be terminated at any time by the Board. Upon termination of the Plan, all amounts in the accounts of 
Participants shall be promptly refunded.

21. Governmental Regulations. The Company’s obligation to sell and deliver Common Stock under the Plan is subject to obtaining all governmental 
approvals required in connection with the authorization, issuance, or sale of such stock.

22. Governing Law. This Plan and all Options and actions taken thereunder shall be governed by, and construed in accordance with, the laws of the State of 
Delaware, applied without regard to conflict of law principles.

23. Issuance of Shares. Shares may be issued upon exercise of an Option from authorized but unissued Common Stock, from shares held in the treasury of 
the Company, or from any other proper source.

24. Tax Withholding. Participation in the Plan is subject to any minimum required tax withholding on income of the Participant in connection with the Plan. 
Each Participant agrees, by entering the Plan, that the Company and its Subsidiaries shall have the right to deduct any such taxes from any payment of any 
kind otherwise due to the Participant, including shares issuable under the Plan.

25. Notification Upon Sale of Shares. Each Participant agrees, by entering the Plan, to give the Company prompt notice of any disposition of shares 
purchased under the Plan where such disposition occurs within two years after the date of grant of the Option pursuant to which such shares were 
purchased or within one year after the date such shares were purchased.

26. Effective Date and Approval of Shareholders. The Plan shall take effect on the date immediately preceding the date on which the Company’s 
registration statement on Form S-1 becomes effective following approval by the holders of a majority of the votes cast at a meeting of stockholders at 
which a quorum is present or by written consent of the stockholders.

(a) Administration of Plan. The Plan shall be administered by the Administrator.

power and authority:

(i) to select the individuals to whom Awards may from time to time be granted;

(ii) to determine the time or times of grant, and the extent, if any, of Non-Qualified Stock Options, Stock Appreciation Rights, Restricted Stock Awards, 
Restricted Stock Units, Unrestricted Stock Awards, and Dividend Equivalent Rights, or any combination of the foregoing, granted to any one or more 
grantees;

(iii) to determine the number of shares of Stock to be covered by any Award;

(iv) to determine and modify from time to time the terms and conditions, including restrictions, not inconsistent with the terms of the Plan, of any Award, 
which terms and conditions may differ among individual Awards and grantees, and to approve the forms of Award Certificates;

(v) to accelerate at any time the exercisability or vesting of all or any portion of any Award;

 
(vi) subject to the provisions of Section 5(c), to extend at any time the period in which Stock Options may be exercised; and

(vii) at any time to adopt, alter and repeal such rules, guidelines and practices for administration of the Plan and for its own acts and proceedings as it shall 
deem advisable; to interpret the terms and provisions of the Plan and any Award (including related written instruments); to make all determinations it 
deems advisable for the administration of the Plan; to decide all disputes arising in connection with the Plan; and to otherwise supervise the administration 
of the Plan.

All decisions and interpretations of the Administrator shall be binding on all persons, including the Company and Plan grantees.

(c) Reserved.

(d) Award Certificate. Awards under the Plan shall be evidenced by Award Certificates that set forth the terms, conditions and limitations for each Award 
which may include, without limitation, the term of an Award and the provisions applicable in the event employment or service terminates.

(e) Indemnification. Neither the Board nor the Administrator, nor any member of either or any delegate thereof, shall be liable for any act, omission, 
interpretation, construction or determination made in good faith in connection with the Plan, and the members of the Board and the Administrator (and any 
delegate thereof) shall be entitled in all cases to indemnification and reimbursement by the Company in respect of any claim, loss, damage or expense 
(including, without limitation, reasonable attorneys’ fees) arising or resulting therefrom to the fullest extent permitted by law and/or under the Company’s 
articles or bylaws or any directors’ and officers’ liability insurance coverage which may be in effect from time to time and/or any indemnification 
agreement between such individual and the Company.

(f) Foreign Award Recipients. Notwithstanding any provision of the Plan to the contrary, in order to comply with the laws in other countries in which the 
Company and its Subsidiaries operate or have employees or other individuals eligible for Awards, the Administrator, in its sole discretion, shall have the 
power and authority to: (i) determine which Subsidiaries shall be covered by the Plan; (ii) determine which individuals outside the United States are 
eligible to participate in the Plan; (iii) modify the terms and conditions of any Award granted to individuals outside the United States to comply with 
applicable foreign laws; (iv) establish subplans and modify exercise procedures and other terms and procedures, to the extent the Administrator determines 
such actions to be necessary or advisable (and such subplans and/or modifications shall be attached to this Plan as appendices); provided, however, that no 
such subplans and/or modifications shall increase the share limitations contained in Section 3(a) hereof; and (v) take any action, before or after an Award is 
made, that the Administrator determines to be necessary or advisable to obtain approval or comply with any local governmental regulatory exemptions or 
approvals. Notwithstanding the foregoing, the Administrator may not take any actions hereunder, and no Awards shall be granted, that would violate the 
Exchange Act or any other applicable United States securities law, the Code, or any other applicable United States governing statute or law.

SECTION 3.

STOCK ISSUABLE UNDER THE PLAN; MERGERS; SUBSTITUTION

(a) Stock Issuable. The maximum number of shares of Stock reserved and available for issuance under the Plan shall be 1,000,000 shares of Stock, subject 
to adjustment as provided in Section 3(c). For purposes of this limitation, the shares of Stock underlying any Awards that are forfeited, canceled, held back 
upon exercise of an Option or settlement of an Award to cover the exercise price or tax withholding, reacquired by the Company prior to vesting, satisfied 
without the issuance of Stock or otherwise terminated (other than by exercise) under the Plan shall be added back to the shares of Stock available for 
issuance under the Plan. In the event the Company repurchases shares of Stock on the open market, such shares shall not be added to the shares of Stock 
available for issuance under the Plan. Subject to such overall limitations, shares of Stock may be issued up to such maximum number pursuant to any type 
or types of Award. The shares available for issuance under the Plan may be authorized but unissued shares of Stock or shares of Stock reacquired by the 
Company.

(b) Reserved.

(c) Changes in Stock. Subject to Section 3(d) hereof, if, as a result of any reorganization, recapitalization, reclassification, stock dividend, stock split, 
reverse stock split or other similar change in the Company’s capital stock, the outstanding shares of Stock are increased or decreased or are exchanged for a 
different number or kind of shares or other securities of the Company, or additional shares or new or different shares or other securities of the Company or 
other non-cash assets are distributed with respect to such shares of Stock or other securities, or, if, as a result of any merger or consolidation, sale of all or 
substantially all of the assets of the Company, the outstanding shares of Stock are converted into or exchanged for securities of the Company or any 
successor entity (or a parent or subsidiary thereof), the Administrator shall make an appropriate or proportionate adjustment in (i) the maximum number of 
shares reserved for issuance under the Plan, (ii) the number and kind of shares or other securities subject to any then outstanding Awards under the Plan, 
(iii) the repurchase price, if any, per share subject to each outstanding Restricted Stock Award, and (iv) the exercise price for each share subject to any then 
outstanding Stock Options and Stock Appreciation Rights under the Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied 
by the number of shares subject to Stock Options and Stock 

 
Appreciation Rights) as to which such Stock Options and Stock Appreciation Rights remain exercisable. The Administrator shall also make equitable or 
proportionate adjustments in the number of shares subject to outstanding Awards and the exercise price and the terms of outstanding Awards to take into 
consideration cash dividends paid other than in the ordinary course or any other extraordinary corporate event. The adjustment by the Administrator shall 
be final, binding and conclusive. No fractional shares of Stock shall be issued under the Plan resulting from any such adjustment, but the Administrator in 
its discretion may make a cash payment in lieu of fractional shares.

(d) Mergers and Other Transactions. In the case of and subject to the consummation of a Sale Event, the parties thereto may cause the assumption or 
continuation of Awards theretofore granted by the successor entity, or the substitution of such Awards with new Awards of the successor entity or parent 
thereof, with appropriate adjustment as to the number and kind of shares and, if appropriate, the per share exercise prices, as such parties shall agree. To the 
extent the parties to such Sale Event do not provide for the assumption, continuation or substitution of Awards, upon the effective time of the Sale Event, 
the Plan and all outstanding Awards granted hereunder shall terminate. In such case, except as may be otherwise provided in the relevant Award Certificate, 
all Options and Stock Appreciation Rights with time-based vesting conditions or restrictions that are not vested and/or exercisable immediately prior to the 
effective time of the Sale Event shall become fully vested and exercisable as of the effective time of the Sale Event, all other Awards with time-based 
vesting, conditions or restrictions shall become fully vested and nonforfeitable as of the effective time of the Sale Event, and all Awards with conditions 
and restrictions relating to the attainment of performance goals may become vested and nonforfeitable in connection with a Sale Event in the 
Administrator’s discretion or to the extent specified in the relevant Award Certificate. In the event of such termination, (i) the Company shall have the 
option (in its sole discretion) to make or provide for a payment, in cash or in kind, to the grantees holding Options and Stock Appreciation Rights, in 
exchange for the cancellation thereof, in an amount equal to the difference between (A) the Sale Price multiplied by the number of shares of Stock subject 
to outstanding Options and Stock Appreciation Rights (to the extent then exercisable at prices not in excess of the Sale Price) and (B) the aggregate 
exercise price of all such outstanding Options and Stock Appreciation Rights (provided that, in the case of an Option or Stock Appreciation Right with an 
exercise price equal to or greater than the Sale Price, such Option or Stock Appreciation Right shall be cancelled for no consideration); or (ii) each grantee 
shall be permitted, within a specified period of time prior to the consummation of the Sale Event as determined by the Administrator, to exercise all 
outstanding Options and Stock Appreciation Rights (to the extent then exercisable) held by such grantee. The Company shall also have the option (in its 
sole discretion) to make or provide for a payment, in cash or in kind, to the grantees holding other Awards in an amount equal to the Sale Price multiplied 
by the number of vested shares of Stock under such Awards.

SECTION 4.

ELIGIBILITY

Grantees under the Plan will be such individuals to whom the Company may issue securities without stockholder approval in accordance with Rule 5635(c)
(4) of the Marketplace Rules of the NASDAQ Stock Market, Inc. and related guidance thereunder, as are selected from time to time by the Administrator in 
its sole discretion.

SECTION 5.

STOCK OPTIONS

(a) Award of Stock Options. The Administrator may grant Stock Options under the Plan. Any Stock Option granted under the Plan shall be a Non-Qualified 
Stock Option and shall be in such form as the Administrator may from time to time approve.

Stock Options granted pursuant to this Section 5 shall be subject to the following terms and conditions and shall contain such additional terms and 
conditions, not inconsistent with the terms of the Plan, as the Administrator shall deem desirable. 

(b) Exercise Price. The exercise price per share for the Stock covered by a Stock Option granted pursuant to this Section 5 shall be determined by the 
Administrator at the time of grant but shall not be less than 100 percent of the Fair Market Value on the date of grant. Notwithstanding the foregoing, Stock 
Options may be granted with an exercise price per share that is less than 100 percent of the Fair Market Value on the date of grant (i) to individuals who are 
not subject to U.S. income tax on the date of grant or (ii) the Stock Option is otherwise compliant with Section 409A.

(c) Option Term. The term of each Stock Option shall be fixed by the Administrator, but no Stock Option shall be exercisable more than ten years after the 
date the Stock Option is granted. 

(d) Exercisability; Rights of a Stockholder. Stock Options shall become exercisable at such time or times, whether or not in installments, as shall be 
determined by the Administrator at or after the grant date. The Administrator may at any time accelerate the exercisability of all or any portion of any Stock 
Option. An optionee shall have the rights of a stockholder only as to shares acquired upon the exercise of a Stock Option and not as to unexercised Stock 
Options.

 
 
(e) Method of Exercise. Stock Options may be exercised in whole or in part, by giving written or electronic notice of exercise to the Company, specifying 
the number of shares to be purchased. Payment of the purchase price may be made by one or more of the following methods except to the extent otherwise 
provided in the Award Certificate:

(i) In cash, by certified or bank check or other instrument acceptable to the Administrator;

(ii) Through the delivery (or attestation to the ownership following such procedures as the Company may prescribe) of shares of Stock that are not then 
subject to restrictions under any Company plan. Such surrendered shares shall be valued at Fair Market Value on the exercise date;

(iii) By the optionee delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to 
the Company cash or a check payable and acceptable to the Company for the purchase price; provided that in the event the optionee chooses to pay the 
purchase price as so provided, the optionee and the broker shall comply with such procedures and enter into such agreements of indemnity and other 
agreements as the Company shall prescribe as a condition of such payment procedure; or

(iv) By a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Stock issuable upon exercise by the largest whole 
number of shares with a Fair Market Value that does not exceed the aggregate exercise price.

Payment instruments will be received subject to collection. The transfer to the optionee on the records of the Company or of the transfer agent of the shares 
of Stock to be purchased pursuant to the exercise of a Stock Option will be contingent upon receipt from the optionee (or a purchaser acting in his stead in 
accordance with the provisions of the Stock Option) by the Company of the full purchase price for such shares and the fulfillment of any other 
requirements contained in the Award Certificate or applicable provisions of laws (including the satisfaction of any withholding taxes that the Company is 
obligated to withhold with respect to the optionee). In the event an optionee chooses to pay the purchase price by previously-owned shares of Stock through 
the attestation method, the number of shares of Stock transferred to the optionee upon the exercise of the Stock Option shall be net of the number of 
attested shares. In the event that the Company establishes, for itself or using the services of a third party, an automated system for the exercise of Stock 
Options, such as a system using an internet website or interactive voice response, then the paperless exercise of Stock Options may be permitted through 
the use of such an automated system.

SECTION 6.

  STOCK APPRECIATION RIGHTS

(a) Award of Stock Appreciation Rights. The Administrator may grant Stock Appreciation Rights under the Plan. A Stock Appreciation Right is an Award 
entitling the recipient to receive shares of Stock (or cash, to the extent explicitly provided for in the applicable Award Certificate) having a value equal to 
the excess of the Fair Market Value of a share of Stock on the date of exercise over the exercise price of the Stock Appreciation Right multiplied by the 
number of shares of Stock with respect to which the Stock Appreciation Right shall have been exercised.

(b) Exercise Price of Stock Appreciation Rights. The exercise price of a Stock Appreciation Right shall not be less than 100 percent of the Fair Market 
Value of the Stock on the date of grant.

(c) Grant and Exercise of Stock Appreciation Rights. Stock Appreciation Rights may be granted by the Administrator independently of any Stock Option 
granted pursuant to Section 5 of the Plan.

(d) Terms and Conditions of Stock Appreciation Rights. Stock Appreciation Rights shall be subject to such terms and conditions as shall be determined on 
the date of grant by the Administrator. The term of a Stock Appreciation Right may not exceed ten years. The terms and conditions of each such Award 
shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees.

SECTION 7.

RESTRICTED STOCK AWARDS

(a) Nature of Restricted Stock Awards. The Administrator may grant Restricted Stock Awards under the Plan. A Restricted Stock Award is any Award of 
Restricted Shares subject to such restrictions and conditions as the Administrator may determine at the time of grant. Conditions may be based on 
continuing employment (or other Service Relationship) and/or achievement of pre-established performance goals and objectives.

(b) Rights as a Stockholder. Upon the grant of the Restricted Stock Award and payment of any applicable purchase price, a grantee shall have the rights of a 
stockholder with respect to the voting of the Restricted Shares and receipt of dividends; provided that if the lapse of restrictions with respect to the 
Restricted Stock Award is tied to the attainment of performance goals, any dividends paid by 

 
 
the Company during the performance period shall accrue and shall not be paid to the grantee until and to the extent the performance goals are met with 
respect to the Restricted Stock Award. Unless the Administrator shall otherwise determine, (i) uncertificated Restricted Shares shall be accompanied by a 
notation on the records of the Company or the transfer agent to the effect that they are subject to forfeiture until such Restricted Shares are vested as 
provided in Section 7(d) below, and (ii) certificated Restricted Shares shall remain in the possession of the Company until such Restricted Shares are vested 
as provided in Section 7(d) below, and the grantee shall be required, as a condition of the grant, to deliver to the Company such instruments of transfer as 
the Administrator may prescribe.

(c) Restrictions. Restricted Shares may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as specifically provided 
herein or in the Restricted Stock Award Certificate. Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to 
Section 16 below, in writing after the Award is issued, if a grantee’s employment (or other Service Relationship) with the Company and its Subsidiaries 
terminates for any reason, any Restricted Shares that have not vested at the time of termination shall automatically and without any requirement of notice to 
such grantee from or other action by or on behalf of, the Company be deemed to have been reacquired by the Company at its original purchase price (if 
any) from such grantee or such grantee’s legal representative simultaneously with such termination of employment (or other Service Relationship), and 
thereafter shall cease to represent any ownership of the Company by the grantee or rights of the grantee as a stockholder. Following such deemed 
reacquisition of Restricted Shares that are represented by physical certificates, a grantee shall surrender such certificates to the Company upon request 
without consideration.

(d) Vesting of Restricted Shares. The Administrator at the time of grant shall specify the date or dates and/or the attainment of pre-established performance 
goals, objectives and other conditions on which the non-transferability of the Restricted Shares and the Company’s right of repurchase or forfeiture shall 
lapse. Subsequent to such date or dates and/or the attainment of such pre-established performance goals, objectives and other conditions, the shares on 
which all restrictions have lapsed shall no longer be Restricted Shares and shall be deemed “vested.”

SECTION 8.

RESTRICTED STOCK UNITS

(a) Nature of Restricted Stock Units. The Administrator may grant Restricted Stock Units under the Plan. A Restricted Stock Unit is an Award of stock 
units that may be settled in shares of Stock (or cash, to the extent explicitly provided for in the applicable Award Certificate) upon the satisfaction of such 
restrictions and conditions at the time of grant. Conditions may be based on continuing employment (or other Service Relationship) and/or achievement of 
pre-established performance goals and objectives. The terms and conditions of each such Award shall be determined by the Administrator, and such terms 
and conditions may differ among individual Awards and grantees. Except in the case of Restricted Stock Units with a deferred settlement date that complies 
with Section 409A, at the end of the vesting period, the Restricted Stock Units, to the extent vested, shall be settled in the form of shares of Stock. 
Restricted Stock Units with deferred settlement dates are subject to Section 409A and shall contain such additional terms and conditions as the 
Administrator shall determine in its sole discretion in order to comply with the requirements of Section 409A.

(b) Rights as a Stockholder. A grantee shall have the rights as a stockholder only as to shares of Stock acquired by the grantee upon settlement of Restricted 
Stock Units; provided, however, that the grantee may be credited with Dividend Equivalent Rights with respect to the stock units underlying his Restricted 
Stock Units, subject to the provisions of Section 11 and such terms and conditions as the Administrator may determine.

(c) Termination. Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 16 below, in writing after 
the Award is issued, a grantee’s right in all Restricted Stock Units that have not vested shall automatically terminate upon the grantee’s termination of 
employment (or cessation of Service Relationship) with the Company and its Subsidiaries for any reason.

SECTION 9.

UNRESTRICTED STOCK AWARDS

Grant or Sale of Unrestricted Stock. The Administrator may grant (or sell at par value or such higher purchase price determined by the Administrator) an 
Unrestricted Stock Award under the Plan. An Unrestricted Stock Award is an Award pursuant to which the grantee may receive shares of Stock free of any 
restrictions under the Plan. Unrestricted Stock Awards may be granted in respect of past services or other valid consideration, or in lieu of cash 
compensation due to such grantee.

SECTION 10.

RESERVED

SECTION 11.

DIVIDEND EQUIVALENT RIGHTS

 
 
 
 
 
(a) Dividend Equivalent Rights. The Administrator may grant Dividend Equivalent Rights under the Plan. A Dividend Equivalent Right is an Award 
entitling the grantee to receive credits based on cash dividends that would have been paid on the shares of Stock specified in the Dividend Equivalent Right 
(or other Award to which it relates) if such shares had been issued to the grantee. A Dividend Equivalent Right may be granted hereunder to any grantee as 
a component of an award of Restricted Stock Units or as a freestanding award. The terms and conditions of Dividend Equivalent Rights shall be specified 
in the Award Certificate. Dividend equivalents credited to the holder of a Dividend Equivalent Right may be paid currently or may be deemed to be 
reinvested in additional shares of Stock, which may thereafter accrue additional equivalents. Any such reinvestment shall be at Fair Market Value on the 
date of reinvestment or such other price as may then apply under a dividend reinvestment plan sponsored by the Company, if any. Dividend Equivalent 
Rights may be settled in cash or shares of Stock or a combination thereof, in a single installment or installments. A Dividend Equivalent Right granted as a 
component of an Award of Restricted Stock Units shall provide that such Dividend Equivalent Right shall be settled only upon settlement or payment of, or 
lapse of restrictions on, such other Award, and that such Dividend Equivalent Right shall expire or be forfeited or annulled under the same conditions as 
such other Award.

(b) Termination. Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 16 below, in writing after 
the Award is issued, a grantee’s rights in all Dividend Equivalent Rights shall automatically terminate upon the grantee’s termination of employment (or 
cessation of Service Relationship) with the Company and its Subsidiaries for any reason.

SECTION 12.

TRANSFERABILITY OF AWARDS

(a) Transferability. Except as provided in Section 12(b) below, during a grantee’s lifetime, his or her Awards shall be exercisable only by the grantee, or by 
the grantee’s legal representative or guardian in the event of the grantee’s incapacity. No Awards shall be sold, assigned, transferred or otherwise 
encumbered or disposed of by a grantee other than by will or by the laws of descent and distribution or pursuant to a domestic relations order. No Awards 
shall be subject, in whole or in part, to attachment, execution, or levy of any kind, and any purported transfer in violation hereof shall be null and void.

(b) Administrator Action. Notwithstanding Section 12(a), the Administrator, in its discretion, may provide either in the Award Certificate regarding a given 
Award or by subsequent written approval that the grantee (who is an employee or director) may transfer his or her Non-Qualified Stock Options to his or 
her immediate family members, to trusts for the benefit of such family members, or to partnerships in which such family members are the only partners, 
provided that the transferee agrees in writing with the Company to be bound by all of the terms and conditions of this Plan and the applicable Award. In no 
event may an Award be transferred by a grantee for value.

(c) Family Member. For purposes of Section 12(b), “family member” shall mean a grantee’s child, stepchild, grandchild, parent, stepparent, grandparent, 
spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, including adoptive 
relationships, any person sharing the grantee’s household (other than a tenant of the grantee), a trust in which these persons (or the grantee) have more than 
50 percent of the beneficial interest, a foundation in which these persons (or the grantee) control the management of assets, and any other entity in which 
these persons (or the grantee) own more than 50 percent of the voting interests.

(d) Designation of Beneficiary. To the extent permitted by the Company, each grantee to whom an Award has been made under the Plan may designate a 
beneficiary or beneficiaries to exercise any Award or receive any payment under any Award payable on or after the grantee’s death. Any such designation 
shall be on a form provided for that purpose by the Administrator and shall not be effective until received by the Administrator. If no beneficiary has been 
designated by a deceased grantee, or if the designated beneficiaries have predeceased the grantee, the beneficiary shall be the grantee’s estate.

SECTION 13.

TAX WITHHOLDING

(a) Payment by Grantee. Each grantee shall, no later than the date as of which the value of an Award or of any Stock or other amounts received thereunder 
first becomes includable in the gross income of the grantee for Federal income tax purposes, pay to the Company, or make arrangements satisfactory to the 
Administrator regarding payment of, any Federal, state, or local taxes of any kind required by law to be withheld by the Company with respect to such 
income. The Company and its Subsidiaries shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind 
otherwise due to the grantee. The Company’s obligation to deliver evidence of book entry (or stock certificates) to any grantee is subject to and conditioned 
on tax withholding obligations being satisfied by the grantee.

(b) Payment in Stock. The Administrator may require the Company’s tax withholding obligation to be satisfied, in whole or in part, by the Company 
withholding from shares of Stock to be issued pursuant to any Award a number of shares with an aggregate Fair Market Value (as of the date the 
withholding is effected) that would satisfy the withholding amount due; provided, however, that the amount withheld does not exceed the maximum 
statutory tax rate or such lesser amount as is necessary to avoid liability accounting treatment. For purposes of share withholding, the Fair Market Value of 
withheld shares shall be determined in the same manner as the value of 

 
 
Stock includible in income of the grantees. The Administrator may also require the Company’s tax withholding obligation to be satisfied, in whole or in 
part, by an arrangement whereby a certain number of shares of Stock issued pursuant to any Award are immediately sold and proceeds from such sale are 
remitted to the Company in an amount that would satisfy the withholding amount due.

SECTION 14.

SECTION 409A AWARDS

Awards are intended to be exempt from Section 409A to the greatest extent possible and to otherwise comply with Section 409A. The Plan and all Awards 
shall be interpreted in accordance with such intent. To the extent that any Award is determined to constitute “nonqualified deferred compensation” within 
the meaning of Section 409A (a “409A Award”), the Award shall be subject to such additional rules and requirements as specified by the Administrator 
from time to time in order to comply with Section 409A. In this regard, if any amount under a 409A Award is payable upon a “separation from service” 
(within the meaning of Section 409A) to a grantee who is then considered a “specified employee” (within the meaning of Section 409A), then no such 
payment shall be made prior to the date that is the earlier of (i) six months and one day after the grantee’s separation from service, or (ii) the grantee’s 
death, but only to the extent such delay is necessary to prevent such payment from being subject to interest, penalties and/or additional tax imposed 
pursuant to Section 409A. Further, the settlement of any such Award may not be accelerated except to the extent permitted by Section 409A.

SECTION 15.

TERMINATION OF SERVICE RELATIONSHIP, TRANSFER, LEAVE OF ABSENCE, ETC.

(a) Termination of Service Relationship. If the grantee’s Service Relationship is with an Affiliate and such Affiliate ceases to be an Affiliate, the grantee 
shall be deemed to have terminated his or her Service Relationship for purposes of the Plan.

(b) For purposes of the Plan, the following events shall not be deemed a termination of a Service Relationship:

(i) a transfer to the employment of the Company from an Affiliate or from the Company to an Affiliate, or from one Affiliate to another; or

(ii) an approved leave of absence for military service or sickness, or for any other purpose approved by the Company, if the employee’s right to re-
employment is guaranteed either by a statute or by contract or under the policy pursuant to which the leave of absence was granted or if the Administrator 
otherwise so provides in writing.

SECTION 
16.

AMENDMENTS AND TERMINATION

The Board may, at any time, amend or discontinue the Plan and the Administrator may, at any time, amend or cancel any outstanding Award for the 
purpose of satisfying changes in law or for any other lawful purpose, but no such action shall materially and adversely affect rights under any outstanding 
Award without the holder’s consent. Except as provided in Section 3(c) or 3(d), without prior stockholder approval, in no event may the Administrator 
exercise its discretion to reduce the exercise price of outstanding Stock Options or Stock Appreciation Rights or effect repricing through cancellation and 
re-grants or cancellation of Stock Options or Stock Appreciation Rights in exchange for cash or other Awards. Nothing in this Section 16 shall limit the 
Administrator’s authority to take any action permitted pursuant to Section 3(c) or 3(d).

SECTION 17.

STATUS OF PLAN

With respect to the portion of any Award that has not been exercised and any payments in cash, Stock or other consideration not received by a grantee, a 
grantee shall have no rights greater than those of a general creditor of the Company unless the Administrator shall otherwise expressly determine in 
connection with any Award or Awards. In its sole discretion, the Administrator may authorize the creation of trusts or other arrangements to meet the 
Company’s obligations to deliver Stock or make payments with respect to Awards hereunder, provided that the existence of such trusts or other 
arrangements is consistent with the foregoing sentence.

SECTION 18.

GENERAL PROVISIONS

(a) No Distribution. The Administrator may require each person acquiring Stock pursuant to an Award to represent to and agree with the Company in 
writing that such person is acquiring the shares without a view to distribution thereof.

 
 
 
 
 
 
(b) Issuance. To the extent certificated, stock certificates to grantees under this Plan shall be deemed delivered for all purposes when the Company or a 
stock transfer agent of the Company shall have mailed such certificates in the United States mail, addressed to the grantee, at the grantee’s last known 
address on file with the Company. Uncertificated Stock shall be deemed delivered for all purposes when the Company or a Stock transfer agent of the 
Company shall have given to the grantee by electronic mail (with proof of receipt) or by United States mail, addressed to the grantee, at the grantee’s last 
known address on file with the Company, notice of issuance and recorded the issuance in its records (which may include electronic “book entry” records). 
Notwithstanding anything herein to the contrary, the Company shall not be required to issue or deliver any evidence of book entry or certificates evidencing 
shares of Stock pursuant to the exercise or settlement of any Award, unless and until the Administrator has determined, with advice of counsel (to the extent 
the Administrator deems such advice necessary or advisable), that the issuance and delivery is in compliance with all applicable laws, regulations of 
governmental authorities and, if applicable, the requirements of any exchange on which the shares of Stock are listed, quoted or traded. Any Stock issued 
pursuant to the Plan shall be subject to any stop-transfer orders and other restrictions as the Administrator deems necessary or advisable to comply with 
federal, state or foreign jurisdiction, securities or other laws, rules and quotation system on which the Stock is listed, quoted or traded. The Administrator 
may place legends on any Stock certificate or notations on any book entry to reference restrictions applicable to the Stock. In addition to the terms and 
conditions provided herein, the Administrator may require that an individual make such reasonable covenants, agreements, and representations as the 
Administrator, in its discretion, deems necessary or advisable in order to comply with any such laws, regulations, or requirements. The Administrator shall 
have the right to require any individual to comply with any timing or other restrictions with respect to the settlement or exercise of any Award, including a 
window-period limitation, as may be imposed in the discretion of the Administrator.

(c) Stockholder Rights. Until Stock is deemed delivered in accordance with Section 18(b), no right to vote or receive dividends or any other rights of a 
stockholder will exist with respect to shares of Stock to be issued in connection with an Award, notwithstanding the exercise of a Stock Option or any other 
action by the grantee with respect to an Award.

(d) Other Compensation Arrangements; No Employment Rights. Nothing contained in this Plan shall prevent the Board from adopting other or additional 
compensation arrangements, including trusts, and such arrangements may be either generally applicable or applicable only in specific cases. The adoption 
of this Plan and the grant of Awards do not confer upon any employee any right to continued employment with the Company or any Subsidiary.

(e) Trading Policy Restrictions. Option exercises and other Awards under the Plan shall be subject to the Company’s insider trading policies and 
procedures, as in effect from time to time.

(f) Clawback Policy. Awards under the Plan shall be subject to the Company’s clawback policy, as in effect from time to time.

SECTION 19.

EFFECTIVE DATE OF PLAN

This Plan shall become effective upon approval by the Board.

SECTION 
20.

GOVERNING LAW

This Plan and all Awards and actions taken thereunder shall be governed by, and construed in accordance with, the laws of the State of Delaware, applied 
without regard to conflict of law principles.

NON-QUALIFIED STOCK OPTION AGREEMENT 
FOR COMPANY EMPLOYEES UNDER THE
ADICET BIO, INC. 
2022 INDUCEMENT PLAN

Name of Optionee:

No. of Option Shares:

Option Exercise Price per Share:

Grant Date:

Expiration Date:

Pursuant to the Adicet Bio, Inc. 2022 Inducement Plan as amended through the date hereof (the “Plan”), Adicet Bio, Inc. (the “Company”) hereby grants to 
the Optionee named above an option (the “Stock Option”) to purchase on or prior to the Expiration Date specified above all or part of the number of shares 
of Common Stock, par value $0.0001 per share (the “Stock”) of the Company specified above at the Option Exercise Price per Share specified above 
subject to the terms and conditions set forth herein and in the Plan. This Stock Option has been granted as an inducement pursuant to Rule 5635(c)(4) of the 
Marketplace Rules of The NASDAQ Stock Market LLC, and consequently is intended to be exempt from the NASDAQ rules regarding stockholder 
approval of equity compensation plans. This Agreement and the terms and conditions of this Stock Option shall be interpreted in accordance with and 
consistent with such exemption. This Stock Option is not intended to be an “incentive stock option” under Section 422 of the Internal Revenue Code of 
1986, as amended. The Plan is discretionary in nature and may be amended, cancelled, or terminated at any time. 

1. Exercisability Schedule. No portion of this Stock Option may be exercised until such portion shall have become exercisable. Except as set forth below, 
and subject to the discretion of the Administrator (as defined in Section 2 of the Plan) to accelerate the exercisability schedule hereunder, this Stock Option 
shall be exercisable with respect to the following number of Option Shares on the dates indicated so long as Optionee remains an employee of the 
Company or a Subsidiary on such dates: 

The Stock Option will vest over a period of four years, with 25% of the shares underlying such option vesting on the first anniversary of the grant and the 
remaining 75% vesting in thirty-six equal monthly installments thereafter. 

Once exercisable, this Stock Option shall continue to be exercisable at any time or times prior to the close of business on the Expiration Date, subject to the 
provisions hereof and of the Plan. 

2. Manner of Exercise. 

(a) The Optionee may exercise this Stock Option only in the following manner: from time to time on or prior to the Expiration Date of this Stock Option, 
the Optionee may give written notice to the Administrator of his or her election to purchase some or all of the Option Shares purchasable at the time of 
such notice. This notice shall specify the number of Option Shares to be purchased. 

Payment of the purchase price for the Option Shares may be made by one or more of the following methods: (i) in cash, by certified or bank check or other 
instrument acceptable to the Administrator; (ii) through the delivery (or attestation to the ownership) of shares of Stock that have been purchased by the 
Optionee on the open market or that are beneficially owned by the Optionee and are not then subject to any restrictions under any Company plan and that 
otherwise satisfy any holding periods as may be required by the Administrator; (iii) by the Optionee delivering to the Company a properly executed 
exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the 
Company to pay the option purchase price, provided that in the event the Optionee chooses to pay the option purchase price as so provided, the Optionee 
and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Administrator shall prescribe as 
a condition of such payment procedure; (iv) by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Stock 
issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price; or (v) a 
combination of (i), (ii), (iii) and (iv) above. Payment instruments will be received subject to collection. 

The transfer to the Optionee on the records of the Company or of the transfer agent of the Option Shares will be contingent upon (i) the Company’s receipt 
from the Optionee of the full purchase price for the Option Shares, as set forth above, (ii) the fulfillment of any other requirements contained herein or in 
the Plan or in any other agreement or provision of laws, and (iii) the receipt by the Company of any agreement, statement or other evidence that the 
Company may require to satisfy itself that the issuance of Stock to be 

 
 
   
   
   
   
 
 
 
   
   
 
 
 
   
   
 
 
 
   
   
 
 
 
   
   
 
purchased pursuant to the exercise of Stock Options under the Plan and any subsequent resale of the shares of Stock will be in compliance with applicable 
laws and regulations. In the event the Optionee chooses to pay the purchase price by previously-owned shares of Stock through the attestation method, the 
number of shares of Stock transferred to the Optionee upon the exercise of the Stock Option shall be net of the Shares attested to. 

(b) The shares of Stock purchased upon exercise of this Stock Option shall be transferred to the Optionee on the records of the Company or of the transfer 
agent upon compliance to the satisfaction of the Administrator with all requirements under applicable laws or regulations in connection with such transfer 
and with the requirements hereof and of the Plan. The determination of the Administrator as to such compliance shall be final and binding on the Optionee. 
The Optionee shall not be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Stock subject to this Stock 
Option unless and until this Stock Option shall have been exercised pursuant to the terms hereof, the Company or the transfer agent shall have transferred 
the shares to the Optionee, and the Optionee’s name shall have been entered as the stockholder of record on the books of the Company. Thereupon, the 
Optionee shall have full voting, dividend and other ownership rights with respect to such shares of Stock. 

(c) [Reserved]. 

(d) Notwithstanding any other provision hereof or of the Plan, no portion of this Stock Option shall be exercisable after the Expiration Date hereof. 

3. Termination of Employment. If the Optionee’s employment by the Company or a Subsidiary (as defined in the Plan) is terminated, the period within 
which to exercise the Stock Option may be subject to earlier termination as set forth below. 

(a) Termination Due to Death. If the Optionee’s employment terminates by reason of the Optionee’s death, any portion of this Stock Option outstanding on 
such date, to the extent exercisable on the date of death, may thereafter be exercised by the Optionee’s legal representative or legatee for a period of 12 
months from the date of death or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of death shall 
terminate immediately and be of no further force or effect. 

(b) Termination Due to Disability. If the Optionee’s employment terminates by reason of the Optionee’s disability (as determined by the Administrator), 
any portion of this Stock Option outstanding on such date, to the extent exercisable on the date of such termination of employment, may thereafter be 
exercised by the Optionee for a period of 12 months from the date of disability or until the Expiration Date, if earlier. Any portion of this Stock Option that 
is not exercisable on the date of disability shall terminate immediately and be of no further force or effect. 

(c) Termination for Cause. If the Optionee’s employment terminates for Cause, any portion of this Stock Option outstanding on such date shall terminate 
immediately and be of no further force and effect. For purposes hereof, “Cause” shall mean, unless otherwise provided in an employment agreement 
between the Company and the Optionee, a determination by the Administrator that the Optionee shall be dismissed as a result of (i) any material breach by 
the Optionee of any agreement between the Optionee and the Company; (ii) the conviction of, indictment for or plea of nolo contendere by the Optionee to 
a felony or a crime involving moral turpitude; or (iii) any material misconduct or willful and deliberate non-performance (other than by reason of disability) 
by the Optionee of the Optionee’s duties to the Company. 

(d) Other Termination. If the Optionee’s employment terminates for any reason other than the Optionee’s death, the Optionee’s disability or Cause, and 
unless otherwise determined by the Administrator, any portion of this Stock Option outstanding on such date may be exercised, to the extent exercisable on 
the date of termination, for a period of three months from the date of termination or until the Expiration Date, if earlier. Any portion of this Stock Option 
that is not exercisable on the date of termination shall terminate immediately and be of no further force or effect. 

The Administrator’s determination of the reason for termination of the Optionee’s employment shall be conclusive and binding on the Optionee and his or 
her representatives or legatees. 

4. Incorporation of Plan. Notwithstanding anything herein to the contrary, this Agreement shall be subject to and governed by all the terms and conditions 
of the Plan, including the powers of the Administrator set forth in Section 2(b) of the Plan. Capitalized terms in this Agreement shall have the meaning 
specified in the Plan, unless a different meaning is specified herein. 

5. Transferability. This Agreement is personal to the Optionee, is non-assignable and is not transferable in any manner, by operation of law or otherwise, 
other than by will or the laws of descent and distribution. This Stock Option is exercisable, during the Optionee’s lifetime, only by the Optionee, and 
thereafter, only by the Optionee’s legal representative or legatee. 

6. Tax Withholding. The Optionee shall, not later than the date as of which the exercise of this Stock Option becomes a taxable event for Federal income 
tax purposes, pay to the Company or make arrangements satisfactory to the Administrator for payment of any Federal, state, and local taxes required by law 
to be withheld on account of such taxable event. The Company shall have the authority to cause the required tax withholding obligation to be satisfied, in 
whole or in part, by withholding from shares of Stock to be issued to 

the Optionee a number of shares of Stock with an aggregate Fair Market Value that would satisfy the withholding amount due; provided, however, that the 
amount withheld does not exceed the maximum statutory tax rate or such lesser amount as is necessary to avoid adverse accounting treatment or as 
determined by the Administrator. 

7. No Obligation to Continue Employment. Neither the Company nor any Subsidiary is obligated by or as a result of the Plan or this Agreement to continue 
the Optionee in employment and neither the Plan nor this Agreement shall interfere in any way with the right of the Company or any Subsidiary to 
terminate the employment of the Optionee at any time. 

8. Integration. This Agreement constitutes the entire agreement between the parties with respect to this Stock Option and supersedes all prior agreements 
and discussions between the parties concerning such subject matter. 

9. Data Privacy Consent. In order to administer the Plan and this Agreement and to implement or structure future equity grants, the Company, its 
subsidiaries and affiliates and certain agents thereof (together, the “Relevant Companies”) may process any and all personal or professional data, including 
but not limited to Social Security or other identification number, home address and telephone number, date of birth and other information that is necessary 
or desirable for the administration of the Plan and/or this Agreement (the “Relevant Information”). By entering into this Agreement, the Optionee (i) 
authorizes the Company to collect, process, register and transfer to the Relevant Companies all Relevant Information; (ii) waives any privacy rights the 
Optionee may have with respect to the Relevant Information; (iii) authorizes the Relevant Companies to store and transmit such information in electronic 
form; and (iv) authorizes the transfer of the Relevant Information to any jurisdiction in which the Relevant Companies consider appropriate. The Optionee 
shall have access to, and the right to change, the Relevant Information. Relevant Information will only be used in accordance with applicable law. 

10. Notices. Notices hereunder shall be mailed or delivered to the Company at its principal place of business and shall be mailed or delivered to the 
Optionee at the address on file with the Company or, in either case, at such other address as one party may subsequently furnish to the other party in 
writing.

by law to be withheld from the Grantee on account of such transfer.

7.

Section 409A of the Code.  This Agreement shall be interpreted in such a manner that all provisions relating to the settlement of the

Exhibit 10.16

This Employment Agreement (“Agreement”) is made between Adicet Bio, Inc., a Delaware corporation (the “Company”), and 

_____________________ (the “Executive”). 

WHEREAS, the Company desires to employ the Executive and the Executive desires to be employed by the Company beginning on 

______________ (the “Effective Date”) on the terms contained herein.

NOW, THEREFORE, in consideration of the mutual covenants and agreements herein contained and other good and valuable consideration, the 

receipt and sufficiency of which is hereby acknowledged, the parties agree as follows:

1.

Employment.

Term.   The term of this Agreement shall commence on the Effective Date and continue until terminated in

(b)

Position and Duties.  The Executive shall serve as the [Title] of the Company and shall have such powers and

Company’s payroll practice over [__]8 months commencing within 60 days after the Date of Termination; provided, however, that if the 60-day period

the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), shall begin to be paid in the second calendar year by the last 
day of such 60-day period; provided, further, that the initial payment shall include a catch-up payment to cover amounts retroactive to the day immediately 
following the Date of Termination.  Each payment pursuant to this Agreement is intended to constitute a separate payment for purposes of Treasury 
Regulation Section 1.409A-2(b)(2).

6.

Change in Control Period.  The provisions of this Section 6 shall apply in lieu of, and expressly supersede, the provisions of Section 5 if (i) the Executive’s

If the Executive’s employment is terminated by the Company without Cause as provided in Section 3(d) or the 

Executive terminates employment for Good Reason as provided in Section 3(e) and in each case the Date of Termination occurs during the Change in

the Company shall pay any unpaid bonus earned for the year preceding the date of Executive’s

(iii)

notwithstanding anything to the contrary in any applicable option agreement or other stock-based

Based Equity Awards”) shall immediately accelerate and become fully vested and exercisable or nonforfeitable as of the later of (i) the Date of 
Termination or (ii) the effective date of the Separation Agreement and Release (the “Accelerated Vesting Date”), provided in order to effectuate 
the accelerated vesting contemplated by this subsection, the unvested portion of the Executive’s options that would otherwise be forfeited on the 
Date of Termination will be delayed until the earlier of (A) the effective date of the Separation Agreement Release (at which time acceleration 
will occur), or (B) the date that the Separation Agreement and Release can no longer become fully effective (at which time the unvested Time-
Based Equity Awards will be terminated or forfeited). Notwithstanding the foregoing, no additional time-based vesting of the Time-Based Equity 
Awards shall occur during the period between the Date of Termination and the Accelerated Vesting Date; and

(iv)

subject to the Executive’s copayment of premium amounts at the applicable active employees’ rate and 
the Executive’s proper election to receive benefits under COBRA, the Company shall pay to the Executive a monthly cash payment (including a

by the last day of such 60-day period.

(b)

Additional Limitation.

(i)

Anything in this Agreement to the contrary notwithstanding, in the event that the amount of any 

compensation, payment or distribution by the Company to or for the benefit of the Executive, whether paid or payable or distributed or 
distributable pursuant to the terms of this Agreement or otherwise, calculated in a manner consistent with Section 280G of the Code, and the 
applicable regulations thereunder (the “Aggregate Payments”), would be subject to the excise tax imposed by Section 4999 of the Code, then the 
Aggregate Payments shall be reduced (but not below zero) so that the sum of all of the Aggregate Payments shall be $1.00 less than the amount 
at which the Executive becomes subject to the excise tax imposed by Section 4999 of the Code; provided that such reduction shall only occur if it 
would result in the Executive receiving a higher After Tax Amount (as defined below) than the Executive would receive if the Aggregate 
Payments were not subject to such reduction.  In such event, the Aggregate Payments shall be reduced in the following order, in each case, in 
reverse chronological order beginning with the Aggregate Payments that are to be paid the furthest in time from consummation of the transaction 
that is subject to Section 280G of the Code:  (1) cash payments not subject to Section 409A of the Code; (2) 

ACTIVE/115800828.1 

 
cash payments subject to Section 409A of the Code; (3) equity-based payments and acceleration; and (4) non-cash forms of benefits; provided 
that in the case of all the foregoing Aggregate Payments all amounts or payments that are not subject to calculation under Treas. Reg. §1.280G-1, 
Q&A-24(b) or (c) shall be reduced before any amounts that are subject to calculation under Treas. Reg. §1.280G-1, Q&A-24(b) or (c).

(ii)

For purposes of this Section 6(b), the “After Tax Amount” means the amount of the Aggregate 

Payments less all federal, state, and local income, excise and employment taxes imposed on the Executive as a result of the Executive’s receipt of 
the Aggregate Payments.  For purposes of determining the After Tax Amount, the Executive shall be deemed to pay federal income taxes at the 
highest marginal rate of federal income taxation applicable to individuals for the calendar year in which the determination is to be made, and 
state and local income taxes at the highest marginal rates of individual taxation in each applicable state and locality, net of the maximum 
reduction in federal income taxes which could be obtained from deduction of such state and local taxes. 

(iii)

The determination as to whether a reduction in the Aggregate Payments shall be made pursuant to 

Section 6(b)(i) shall be made by a nationally recognized accounting firm selected by the Company (the “Accounting Firm”), which shall provide 
detailed supporting calculations both to the Company and the Executive within 15 business days of the Date of Termination, if applicable, or at 
such earlier time as is reasonably requested by the Company or the Executive.  Any determination by the Accounting Firm shall be binding upon 
the Company and the Executive.

(c)

Definitions.  For purposes of this Section 6, the following terms shall have the following meanings:

“Change in Control” shall mean any of the following:

(i)

any “person,” as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, 

as amended (the “Act”), any of its subsidiaries, or any trustee, fiduciary or other person or entity holding securities under any employee benefit 
plan or trust of the Company or any of its subsidiaries), together with all “affiliates” and “associates” (as such terms are defined in Rule 12b-2 
under the Act) of such person, shall become the “beneficial owner” (as such term is defined in Rule 13d-3 under the Act), directly or indirectly, 
of securities of the Company representing 50 percent or more of the combined voting power of the Company’s then outstanding securities having 
the right to vote in an election of the Board (“Voting Securities”) (in such case other than as a result of an acquisition of securities directly from 
the Company); or 

whose appointment or election is not endorsed by a majority of the members of the Board before the date of the appointment or election; or 

(ii)

the date a majority of the members of the Board is replaced during any 12-month period by directors 

(iii)

the consummation of (A) any consolidation or merger of the Company where the stockholders of the 

Company, immediately prior to the consolidation or merger, would not, immediately after the consolidation or merger, beneficially own (as such 
term is defined in Rule 13d-3 under the Act), directly or indirectly, shares representing in the aggregate more than 50 percent of the voting shares 
of the Company issuing cash or securities in the consolidation or merger (or of its ultimate parent corporation, if any), or (B) any sale or other 
transfer (in one transaction or a series of transactions contemplated or arranged by any party as a single plan) of all or substantially all of the 
assets of the Company. 

Notwithstanding the foregoing, a “Change in Control” shall not be deemed to have occurred for purposes of the foregoing clause (i) solely as the 
result of an acquisition of securities by the Company which, by reducing the number of shares of Voting Securities outstanding, increases the proportionate 
number of Voting Securities beneficially owned by any person to 50 percent or more of the combined voting power of all of the then outstanding Voting 
Securities; provided, however, that if any person referred to in this sentence shall thereafter become the beneficial owner of any additional shares of Voting 
Securities (other than pursuant to a stock split, stock dividend, or similar transaction or as a result of an acquisition of securities directly from the 
Company) and immediately 

ACTIVE/115800828.1 

 
thereafter beneficially owns 50 percent or more of the combined voting power of all of the then outstanding Voting Securities, then a “Change in Control” 
shall be deemed to have occurred for purposes of the foregoing clause (i).

7.

Section 409A.

(a)

Anything in this Agreement to the contrary notwithstanding, if at the time of the Executive’s separation from 
service within the meaning of Section 409A of the Code, the Company determines that the Executive is a “specified employee” within the meaning of 
Section 409A(a)(2)(B)(i) of the Code, then to the extent any payment or benefit that the Executive becomes entitled to under this Agreement or otherwise 
on account of the Executive’s separation from service would be considered deferred compensation otherwise subject to the 20 percent additional tax 
imposed pursuant to Section 409A(a) of the Code as a result of the application of Section 409A(a)(2)(B)(i) of the Code, such payment shall not be payable 
and such benefit shall not be provided until the date that is the earlier of (A) six months and one day after the Executive’s separation from service, or (B) 
the Executive’s death.  If any such delayed cash payment is otherwise payable on an installment basis, the first payment shall include a catch-up payment 
covering amounts that would otherwise have been paid during the six-month period but for the application of this provision, and the balance of the 
installments shall be payable in accordance with their original schedule. 

(b)

All in-kind benefits provided and expenses eligible for reimbursement under this Agreement shall be provided by 

the Company or incurred by the Executive during the time periods set forth in this Agreement.  All reimbursements shall be paid as soon as 
administratively practicable, but in no event shall any reimbursement be paid after the last day of the taxable year following the taxable year in which the 
expense was incurred.  The amount of in-kind benefits provided or reimbursable expenses incurred in one taxable year shall not affect the in-kind benefits 
to be provided or the expenses eligible for reimbursement in any other taxable year (except for any lifetime or other aggregate limitation applicable to 
medical expenses).  Such right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit.

(c)

To the extent that any payment or benefit described in this Agreement constitutes “non-qualified deferred 

compensation” under Section 409A of the Code, and to the extent that such payment or benefit is payable upon the Executive’s termination of employment, 
then such payments or benefits shall be payable only upon the Executive’s “separation from service.”  The determination of whether and when a separation 
from service has occurred shall be made in accordance with the presumptions set forth in Treasury Regulation Section 1.409A‑1(h).

(d)

The parties intend that this Agreement will be administered in accordance with Section 409A of the Code.  To the 
extent that any provision of this Agreement is ambiguous as to its compliance with Section 409A of the Code, the provision shall be read in such a manner 
so that all payments hereunder comply with Section 409A of the Code.  Each payment pursuant to this Agreement or the Restrictive Covenants Agreement 
is intended to constitute a separate payment for purposes of Treasury Regulation Section 1.409A‑2(b)(2).  The parties agree that this Agreement may be 
amended, as reasonably requested by either party, and as may be necessary to fully comply with Section 409A of the Code and all related rules and 
regulations in order to preserve the payments and benefits provided hereunder without additional cost to either party.

(e)

The Company makes no representation or warranty and shall have no liability to the Executive or any other 

person if any provisions of this Agreement are determined to constitute deferred compensation subject to Section 409A of the Code but do not satisfy an 
exemption from, or the conditions of, such Section.

8.

Continuing Obligations.

purposes of this Agreement, the obligations in this Section 8 and those that arise in the Restrictive Covenants Agreement and any other agreement relating 
to confidentiality, assignment of inventions, or other restrictive covenants shall collectively be referred to as the “Continuing Obligations.”

ACTIVE/115800828.1 

 
(b)

Third-Party Agreements and Rights.  The Executive hereby confirms that the Executive is not bound by the terms

confidentiality restrictions (if any), or the Executive’s engagement in any business. The Executive represents to the Company that the Executive’s execution 
of this Agreement, the Executive’s employment with the Company and the performance of the Executive’s proposed duties for the Company will not 
violate any obligations the Executive may have to any such previous employer or other party.  In the Executive’s work for the Company, the Executive will 
not disclose or make use of any information in violation of any agreements with or rights of any such previous employer or other party, and the Executive 
will not bring to the premises of the Company any copies or other tangible embodiments of non-public information belonging to or obtained from any such 
previous employment or other party.

(c)

Litigation and Regulatory Cooperation.  During and after the Executive’s employment, the Executive shall

or on behalf of the Company which relate to events or occurrences that transpired while the Executive was employed by the Company, and (ii) the 
investigation, whether internal or external, of any matters about which the Company believes the Executive may have knowledge or information.  The 
Executive’s full cooperation in connection with such claims, actions or investigations shall include, but not be limited to, being available to meet with 
counsel to answer questions or to prepare for discovery or trial and to act as a witness on behalf of the Company at mutually convenient times.  During and 
after the Executive’s employment, the Executive also shall cooperate fully with the Company in connection with any investigation or review of any federal, 
state or local regulatory authority as any such investigation or review relates to events or occurrences that transpired while the Executive was employed by 
the Company.  The Company shall reimburse the Executive for any reasonable out‑of‑pocket expenses incurred in connection with the Executive’s 
performance of obligations pursuant to this Section 8(c).

(d)

Relief. The Executive agrees that it would be difficult to measure any damages caused to the Company which 
might result from any breach by the Executive of the Continuing Obligations, and that in any event money damages would be an inadequate remedy for 
any such breach. Accordingly, the Executive agrees that if the Executive breaches, or proposes to breach, any portion of the Continuing Obligations, the 
Company shall be entitled, in addition to all other remedies that it may have, to an injunction or other appropriate equitable relief to restrain any such 
breach without showing or proving any actual damage to the Company.

9.

Arbitration of Disputes.

(a)

Arbitration Generally.  Any controversy or claim arising out of or relating to this Agreement or the breach thereof 

or otherwise arising out of the Executive’s employment or the termination of that employment (including, without limitation, any claims of unlawful 
employment discrimination or retaliation, whether based on race, religion, national origin, sex, gender, age, disability, sexual orientation, or any other 
protected class under applicable law) shall, to the fullest extent permitted by law, be settled by arbitration in any forum and form agreed upon by the parties 
or, in the absence of such an agreement, under the auspices of JAMS in [Boston, Massachusetts/San Francisco, California] in accordance with the JAMS 
Employment Arbitration Rules, including, but not limited to, the rules and procedures applicable to the selection of arbitrators.  The Executive understands 
that the Executive may only bring such claims in the Executive’s individual capacity, and not as a plaintiff or class member in any purported class 
proceeding or any purported representative proceeding.   The Executive further understands that, by signing this Agreement, the Company and the 
Executive are giving up any right they may have to a jury trial on all claims they may have against each other.  Judgment upon the award rendered by the 
arbitrator may be entered in any court having jurisdiction thereof.  This Section 9 shall be specifically enforceable. Notwithstanding the foregoing, this 
Section 9 shall not preclude either party from pursuing a court action for the sole purpose of obtaining a temporary restraining order or a preliminary 
injunction in circumstances in which such relief is appropriate, including without limitation relief sought under the Restrictive Covenants Agreement; 
provided that any other relief shall be pursued through an arbitration proceeding pursuant to this Section 9.

(b)

Arbitration Fees and Costs.  The Executive shall be required to pay an arbitration fee to initiate any arbitration 

equal to what the Executive would be charged as a first appearance fee in court. The Company shall advance the remaining fees and costs of the arbitrator.  
However, to the extent permissible under the 

ACTIVE/115800828.1 

 
law, and following the arbitrator’s ruling on the matter, the arbitrator may rule that the arbitrator’s fees and costs be distributed in an alternative manner.  
Each party shall pay its own costs and attorneys’ fees, if any. If, however, any party prevails on a statutory or contractual claim that affords the prevailing 
party attorneys’ fees (including pursuant to this Agreement), the arbitrator may award attorneys’ fees to the prevailing party to the extent permitted by law.

10.

Consent to Jurisdiction.  The parties hereby consent to the jurisdiction of the state and federal courts of the [State/Commonwealth] of 

[California/Massachusetts].  Accordingly, with respect to any such court action, the Executive (a) submits to the exclusive personal jurisdiction of such 
courts; (b) consents to service of process; and (c) waives any other requirement (whether imposed by statute, rule of court, or otherwise) with respect to 
personal jurisdiction or service of process.

11.

Integration.  This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and 

supersedes all prior agreements between the parties concerning such subject matter, provided that, the Restrictive Covenants Agreement remains in full 
force and effect.

12.

Withholding; Tax Effect.  All payments made by the Company to the Executive under this Agreement shall be net of any tax or other 

amounts required to be withheld by the Company under applicable law.  Nothing in this Agreement shall be construed to require the Company to make any 
payments to compensate the Executive for any adverse tax effect associated with any payments or benefits or for any deduction or withholding from any 
payment or benefit.  

13.

Successors and Assigns.  Neither the Executive nor the Company may make any assignment of this Agreement or any interest in it, by 

operation of law or otherwise, without the prior written consent of the other; provided, however, that the Company may assign its rights and obligations 
under this Agreement (including the Restrictive Covenants Agreement) without the Executive’s consent to any affiliate or to any person or entity with 
whom the Company shall hereafter effect a reorganization or consolidation, into which the Company merges or to whom it transfers all or substantially all 
of its properties or assets; provided further that if the Executive remains employed or becomes employed by the Company, the purchaser or any of their 
affiliates in connection with any such transaction, then the Executive shall not be entitled to any payments, benefits or vesting pursuant to Section 5 or 
pursuant to Section 6 of this Agreement solely as a result of such transaction.  This Agreement shall inure to the benefit of and be binding upon the 
Executive and the Company, and each of the Executive’s and the Company’s respective successors, executors, administrators, heirs and permitted assigns.  
In the event of the Executive’s death after the Executive’s termination of employment but prior to the completion by the Company of all payments due to 
the Executive under this Agreement, the Company shall continue such payments to the Executive’s beneficiary designated in writing to the Company prior 
to the Executive’s death (or to the Executive’s estate, if the Executive fails to make such designation).

14.

Enforceability.  If any portion or provision of this Agreement (including, without limitation, any portion or provision of any section of 

this Agreement) shall to any extent be declared illegal or unenforceable by a court of competent jurisdiction, then the remainder of this Agreement, or the 
application of such portion or provision in circumstances other than those as to which it is so declared illegal or unenforceable, shall not be affected 
thereby, and each portion and provision of this Agreement shall be valid and enforceable to the fullest extent permitted by law.

15.

Survival. The provisions of this Agreement shall survive the termination of this Agreement and/or the termination of the Executive’s 

employment to the extent necessary to effectuate the terms contained herein.

16.

Waiver. No waiver of any provision hereof shall be effective unless made in writing and signed by the waiving party. The failure of 
any party to require the performance of any term or obligation of this Agreement, or the waiver by any party of any breach of this Agreement, shall not 
prevent any subsequent enforcement of such term or obligation or be deemed a waiver of any subsequent breach.

17.

Notices. Any notices, requests, demands and other communications provided for by this Agreement shall be sufficient if in writing and 
delivered in person or sent by a nationally recognized overnight courier service or by registered or certified mail, postage prepaid, return receipt requested, 
to the Executive at the last address the 

ACTIVE/115800828.1 

 
Executive has filed in writing with the Company or, in the case of the Company, at its main offices, attention of the Board.

18.

Amendment.  This Agreement may be amended or modified only by a written instrument signed by the Executive and by a duly 

authorized representative of the Company.

19.

Effect on Other Plans and Agreements.  An election by the Executive to resign for Good Reason under the provisions of this 

Agreement shall not be deemed a voluntary termination of employment by the Executive for the purpose of interpreting the provisions of any of the 
Company's benefit plans, programs or policies.  Nothing in this Agreement shall be construed to limit the rights of the Executive under the Company’s 
benefit plans, programs or policies except as otherwise provided in Section 8 hereof, and except that the Executive shall have no rights to any severance 
benefits under any Company severance pay plan, offer letter or otherwise.  In the event that the Executive is party to an agreement with the Company 
providing for payments or benefits under such plan or agreement and under this Agreement, the terms of this Agreement shall govern and the Executive 
may receive payment under this Agreement only and not both.  Further, Section 5 and Section 6 of this Agreement are mutually exclusive and in no event 
shall the Executive be entitled to payments or benefits pursuant to both Section 5 and Section 6 of this Agreement.  

20.

Governing Law.  This is a [California/Massachusetts] contract and shall be construed under and be governed in all respects by the laws 

of the [State/Commonwealth] of [California/Massachusetts], without giving effect to the conflict of laws principles thereof.  With respect to any disputes 
concerning federal law, such disputes shall be determined in accordance with the law as it would be interpreted and applied by the United States Court of 
Appeals for the [9th/1st]Circuit.

21.

[Conditions.  Notwithstanding anything to the contrary herein, the effectiveness of this Agreement shall be conditioned on (i) the 

Executive’s satisfactory completion of reference and background checks, if so requested by the Company, and (ii) the Executive’s submission of 
satisfactory proof of the Executive’s legal authorization to work in the United States.]10

22.

Counterparts.  This Agreement may be executed in any number of counterparts, each of which when so executed and delivered shall 

be taken to be an original; but such counterparts shall together constitute one and the same document.

FORM OF DIRECTOR INDEMNIFICATION AGREEMENT

Exhibit 10.17

This Indemnification Agreement (“Agreement”) is made as of [________] by and between Adicet Bio, Inc., a Delaware 

corporation (the “Company”), and [Director] (“Indemnitee”).

RECITALS

WHEREAS, the Company desires to attract and retain the services of highly qualified individuals, such as Indemnitee, to 

serve the Company;

WHEREAS,  in  order  to  induce  Indemnitee  to  provide  or  continue  to  provide  services  to  the  Company,  the  Company 
wishes to provide for the indemnification of, and advancement of expenses to, Indemnitee to the maximum extent permitted by 
law;

WHEREAS, the Third Amended and Restated Certificate of Incorporation (as amended and in effect from time to time, 
the  “Charter”)  and  the  Amended  and  Restated  Bylaws  (as  amended  and  in  effect  from  time  to  time,  the  “Bylaws”)  of  the 
Company  require  indemnification  of  the  officers  and  directors  of  the  Company,  and  Indemnitee  may  also  be  entitled  to 
indemnification pursuant to the General Corporation Law of the State of Delaware (the “DGCL”); 

WHEREAS,  the  Charter,  the  Bylaws  and  the  DGCL  expressly  provide  that  the  indemnification  provisions  set  forth 
therein are not exclusive, and thereby contemplate that contracts may be entered into between the Company and members of the 
board of directors, officers and other persons with respect to indemnification;

WHEREAS,  the  Board  of  Directors  of  the  Company  (the  “Board”)  has  determined  that  the  increased  difficulty  in 
attracting  and  retaining  highly  qualified  persons  such  as  Indemnitee  is  detrimental  to  the  best  interests  of  the  Company’s 
stockholders;

WHEREAS, it is reasonable and prudent for the Company contractually to obligate itself to indemnify, and to advance 
expenses on behalf of, such persons to the fullest extent permitted by applicable law, regardless of any amendment or revocation 
of the Charter or the Bylaws, so that they will serve or continue to serve the Company free from undue concern that they will not 
be so indemnified; 

WHEREAS, this Agreement is a supplement to and in furtherance of the indemnification provided in the Charter, the 
Bylaws and any resolutions adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate 
any rights of Indemnitee thereunder; and

[WHEREAS, Indemnitee has certain rights to indemnification and/or insurance provided by [  ] (“[•]”) which Indemnitee 
and [•] intend to be secondary to the primary obligation of the Company to indemnify Indemnitee as provided in this Agreement, 
with the Company’s acknowledgment and agreement to the foregoing being a material condition to Indemnitee’s willingness to 
serve or continue to serve on the Board.]

NOW, THEREFORE, in consideration of the premises and the covenants contained herein, the Company and Indemnitee 

do hereby covenant and agree as follows:

Section  1.                Services  to  the  Company.    Indemnitee  agrees  to  [continue  to]  serve  as  a  director  of  the  Company.  
Indemnitee  may  at  any  time  and  for  any  reason  resign  from  such  position  (subject  to  any  other  contractual  obligation  or  any 
obligation imposed by law), in which event the Company shall have no obligation under this Agreement to continue Indemnitee 
in such position.  This Agreement shall not be deemed an employment contract between the Company (or any of its subsidiaries 
or any Enterprise) and Indemnitee.

any of such Person’s Affiliates or Associates that gives such Person or any of such Person’s Affiliates or Associates the 
economic equivalent of ownership of an amount of securities due to the fact that the value of the derivative security is 
explicitly determined by reference to the price or value of such securities, or that provides such Person or any of such 
Person’s Affiliates or Associates an opportunity, directly or indirectly, to profit or to share in any profit derived from any 
change in the value of such securities, in any case without regard to whether (A) such derivative security conveys any

combined voting power of the Company’s then outstanding securities unless the change in relative Beneficial Ownership 
of the Company’s securities by any Person results solely from a reduction in the aggregate number of outstanding shares 
of  securities  entitled  to  vote  generally  in  the  election  of  directors  [or  as  a  result  of  conversions  of  Class  B  Common 
Stock], provided that a Change of Control shall be deemed to have occurred if subsequent to such reduction such Person

Person any additional voting power;

Indemnitee in any matter material to any such party; or (ii) any other party to the Proceeding giving rise to a claim for 
indemnification hereunder.  Notwithstanding the foregoing, the term “Independent Counsel” shall not include any person 
who,  under  the  applicable  standards  of  professional  conduct  then  prevailing,  would  have  a  conflict  of  interest  in 
representing either the Company or Indemnitee in an action to determine Indemnitee’s rights under this Agreement.  The 
Company  agrees  to  pay  the  reasonable  fees  and  expenses  of  the  Independent  Counsel  referred  to  above  and  to  fully

criminal, administrative, regulatory or investigative nature, and whether formal or informal, in which Indemnitee was, is

or was serving at the request of the Company as a director, manager, partner, officer, employee, agent or trustee of any 
Enterprise or by reason 

ACTIVE/105004718.3

of any action taken by Indemnitee or of any action taken on his or her part while acting as a director of the Company or 
while serving at the request of the Company as a director, manager, partner, officer, employee, agent or trustee of any 
Enterprise, in each case whether or not serving in such capacity at the time any liability or expense is incurred for which 
indemnification, reimbursement or advancement of expenses can be provided under this Agreement; provided, however, 
that  the  term  “Proceeding”  shall  not  include  any  action,  suit  or  arbitration,  or  part  thereof,  initiated  by  Indemnitee  to 
enforce Indemnitee’s rights under this Agreement as provided for in Section 12(a) of this Agreement.

Section 3.        Indemnity in Third-Party Proceedings.  The Company shall indemnify Indemnitee to the extent set forth 
in  this  Section  3  if  Indemnitee  is,  or  is  threatened  to  be  made,  a  party  to  or  a  participant  in  any  Proceeding,  other  than  a 
Proceeding by or in the right of the Company to procure a judgment in its favor.  Pursuant to this Section 3, Indemnitee shall be 
indemnified  against  all  Expenses,  judgments,  fines,  penalties,  excise  taxes,  and  amounts  paid  in  settlement  actually  and 
reasonably  incurred  by  Indemnitee  or  on  his  or  her  behalf  in  connection  with  such  Proceeding  or  any  claim,  issue  or  matter 
therein,  if  Indemnitee  acted  in  good  faith  and  in  a  manner  he  or  she  reasonably  believed  to  be  in  or  not  opposed  to  the  best 
interests of the Company and, in the case of a criminal proceeding, had no reasonable cause to believe that his or her conduct was 
unlawful.  

Section 4.        Indemnity in Proceedings by or in the Right of the Company.  The Company shall indemnify Indemnitee 
to the extent set forth in this Section 4 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding 
by or in the right of the Company to procure a judgment in its favor.  Pursuant to this Section 4, Indemnitee shall be indemnified 
against all Expenses actually and reasonably incurred by Indemnitee or on his or her behalf in connection with such Proceeding 
or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner he or she reasonably believed to be in or 
not opposed to the best interests of the Company. No indemnification for Expenses shall be made under this Section 4 in respect 
of any claim, issue or matter as to which Indemnitee shall have been finally adjudged by a court to be liable to the Company, 
unless and only to the extent that the Delaware Court of Chancery (the “Delaware Court”) shall determine upon application that, 
despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to 
indemnification for such expenses as the Delaware Court shall deem proper.

Section 5.        Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any other 
provisions of this Agreement and except as provided in Section 7, to the extent that Indemnitee is a party to or a participant in 
any  Proceeding  and  is  successful  in  such  Proceeding  or  in  defense  of  any  claim,  issue  or  matter  therein,  the  Company  shall 
indemnify  Indemnitee  against  all  Expenses  actually  and  reasonably  incurred  by  him  or  her  in  connection  therewith.    If 
Indemnitee  is  not  wholly  successful  in  such  Proceeding  but  is  successful  as  to  one  or  more  but  less  than  all  claims,  issues  or 
matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by 
Indemnitee  or  on  his  or  her  behalf  in  connection  with  each  successfully  resolved  claim,  issue  or  matter.    For  purposes  of  this 
Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without 
prejudice, shall be deemed to be a successful result as to such claim, issue or matter.

Section 6.        Reimbursement for Expenses of a Witness or in Response to a Subpoena.  Notwithstanding  any  other 
provision  of  this  Agreement,  to  the  extent  that  Indemnitee,  by  reason  of  his  or  her  Corporate  Status,  (i)  is  a  witness  in  any 
Proceeding to which Indemnitee is not a party and is not threatened to be made a party or (ii) receives a subpoena with respect to 
any  Proceeding  to  which  Indemnitee  is  not  a  party  and  is  not  threatened  to  be  made  a  party,  the  Company  shall  reimburse 
Indemnitee for all Expenses actually and reasonably incurred by him or her or on his or her behalf in connection therewith.

Section 7.        Exclusions.  Notwithstanding any provision in this Agreement to the contrary, the Company shall not be 

obligated under this Agreement:  

(a)        to indemnify for amounts otherwise indemnifiable hereunder (or for which advancement is provided 
hereunder)  if  and  to  the  extent  that  Indemnitee  has  otherwise  actually  received  such  amounts  under  any  insurance  policy, 
contract, agreement or otherwise; provided that the foregoing shall not [i] apply to any personal or umbrella liability insurance 
maintained by Indemnitee, [or (ii) affect the rights of Indemnitee or the Fund Indemnitors as set forth in Section 13(c)];

(b)       to indemnify for an accounting of profits made from the purchase and sale (or sale and purchase) by 
Indemnitee  of  securities  of  the  Company  within  the  meaning  of  Section  16(b)  of  the  Securities  Exchange  Act  of  1934,  as 
amended,  or  similar  provisions  of  state  statutory  law  or  common  law,  or  from  the  purchase  or  sale  by  Indemnitee  of  such 
securities in violation of Section 306 of the Sarbanes Oxley Act of 2002 (“SOX”);

(c)                to  indemnify  with  respect  to  any  Proceeding,  or  part  thereof,  brought  by  Indemnitee  against  the 
Company, any legal entity which it controls, any director or officer thereof or any third party, unless (i) the Board has consented 
to  the  initiation  of  such  Proceeding  or  part  thereof  and  (ii)  the  Company  provides  the  indemnification,  in  its  sole  discretion, 
pursuant to the powers vested in the Company under applicable law; provided, however, that this Section 7(c) shall not apply to 
(A)  counterclaims  or  affirmative  defenses  asserted  by  Indemnitee  in  an  action  brought  against  Indemnitee  or  (B)  any  action 
brought by Indemnitee for indemnification or advancement from the Company under this Agreement or under any directors’ and 
officers’ liability insurance policies maintained by the Company in the suit for which indemnification or advancement is being 
sought as described in Section 12; or

law exists at the time payment would otherwise be required pursuant to this Agreement).

(d)       to provide any indemnification or advancement of expenses that is prohibited by applicable law (as such 

Section 8.        Advancement of Expenses.  Subject to Section 9(b), the Company shall advance the Expenses incurred by 
Indemnitee in connection with any Proceeding, and such advancement shall be made as incurred, and such advancement shall be 
made within thirty (30) days after the receipt by the Company of a statement or statements requesting such advances (including 
any  invoices  received  by  Indemnitee,  which  such  invoices  may  be  redacted  as  necessary  to  avoid  the  waiver  of  any  privilege 
accorded by applicable law) from time to time, whether prior to or after final disposition of any Proceeding.  Advances shall be 
unsecured and interest free.  Advances shall be made without regard to Indemnitee’s (i) ability to repay the expenses, (ii) ultimate 
entitlement to indemnification under the other provisions of this Agreement, and (iii) entitlement to and availability of insurance 
coverage, including advancement, payment or reimbursement of defense costs, expenses of covered loss under the provisions of 
any  applicable  insurance  policy  (including,  without  limitation,  whether  such  advancement,  payment  or  reimbursement  is 
withheld, conditioned or delayed by the insurer(s)).  Indemnitee shall qualify for advances upon the execution and delivery to the 
Company  of  this  Agreement  which  shall  constitute  an  undertaking  providing  that  Indemnitee  undertakes  to  the  fullest  extent 
required by law to repay the advance if and to the extent that it is ultimately determined by a court of competent jurisdiction in a 
final  judgment,  not  subject  to  appeal,  that  Indemnitee  is  not  entitled  to  be  indemnified  by  the  Company.    No  other  form  of 
undertaking shall be required. The right to advances under this paragraph shall in all events continue until final disposition of any 
Proceeding, including any appeal therein.  Nothing in this Section 8 shall limit Indemnitee’s right to advancement pursuant to 
Section 12(e) of this Agreement.

Section 9.       Procedure for Notification and Defense of Claim.

(a)                To  obtain  indemnification  under  this  Agreement,  Indemnitee  shall  submit  to  the  Company  a  written 
request therefor specifying the basis for the claim, the amounts for which Indemnitee is seeking payment under this Agreement, 
and all documentation related thereto as reasonably requested by the Company.  

(b)       In the event that the Company shall be obligated hereunder to provide indemnification for or make any 
advancement  of  Expenses  with  respect  to  any  Proceeding,  the  Company  shall  be  entitled  to  assume  the  defense  of  such 
Proceeding,  or  any  claim,  issue  or  matter  therein,  with  counsel  approved  by  Indemnitee  (which  approval  shall  not  be 
unreasonably withheld or delayed) upon the delivery to Indemnitee of written notice of the Company’s election to do so.  After 
delivery of such notice, approval of such counsel by Indemnitee and the retention of such counsel by the Company, the Company 
will not be liable to Indemnitee under this Agreement for any fees or expenses of separate counsel subsequently employed by or 
on behalf of Indemnitee with respect to the same Proceeding; provided that (i) Indemnitee shall have the right to employ separate 
counsel in any such Proceeding at Indemnitee’s expense and (ii) if (A) the employment of separate counsel by Indemnitee has 
been  previously  authorized  by  the  Company,  (B)  Indemnitee  shall  have  reasonably  concluded  that  there  may  be  a  conflict  of 
interest between the Company and Indemnitee in the conduct of such defense, (C) the Company shall not continue to retain such 
counsel  to  defend  such  Proceeding,  or  (D)  a  Change  in  Control  shall  have  occurred,  then  the  fees  and  expenses  actually  and 
reasonably incurred by Indemnitee with respect to his or her separate counsel shall be Expenses hereunder.  

above, then the Company will be entitled to participate in the Proceeding at its own expense.

(c)        In the event that the Company does not assume the defense in a Proceeding pursuant to paragraph (b) 

(d)       The Company shall not be liable to indemnify Indemnitee under this Agreement for any amounts paid in 
settlement  of  any  Proceeding  effected  without  its  prior  written  consent  (which  consent  shall  not  be  unreasonably  withheld  or 
delayed).  The  Company  shall  not,  without  the  prior  written  consent  of  Indemnitee  (which  consent  shall  not  be  unreasonably 
withheld or delayed), enter into any settlement which (i) includes an admission of fault of Indemnitee, any non-monetary remedy 
imposed on Indemnitee or any monetary damages for which Indemnitee is not wholly and actually indemnified hereunder or (ii) 
with respect to any Proceeding with respect to which Indemnitee may be or is made a party or may be otherwise entitled to seek 
indemnification hereunder, does not include the full release of Indemnitee from all liability in respect of such Proceeding.

Section 10.      Procedure Upon Application for Indemnification.

(a)        Upon written request by Indemnitee for indemnification pursuant to Section 9(a), a determination, if 
such determination is required by applicable law, with respect to Indemnitee’s entitlement to indemnification hereunder shall be 
made  in  the  specific  case  by  one  of  the  following  methods:    (x)  if  a  Change  in  Control  shall  have  occurred,  by  Independent 
Counsel in a written opinion to the Board; or (y) if a Change in Control shall not have occurred: (i) by a majority vote of the 
disinterested directors, even though less than a quorum; (ii) by a committee of disinterested directors designated by a majority 
vote  of  the  disinterested  directors,  even  though  less  than  a  quorum;  or  (iii)  if  there  are  no  disinterested  directors  or  if  the 
disinterested directors so direct, by Independent Counsel in a written opinion to the Board.  For purposes hereof, disinterested 
directors are those members of the Board who are not parties to the action, suit or proceeding in respect of which indemnification 
is sought.  In the case that such determination is made by Independent Counsel, a copy of Independent Counsel’s written opinion 
shall be delivered to Indemnitee and, if it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee 
shall be made within thirty (30) days after such determination.  Indemnitee shall cooperate with the Independent Counsel or the 
Company,  as  applicable,  in  making  such  determination  with  respect  to  Indemnitee’s  entitlement  to  indemnification,  including 
providing to 

ACTIVE/105004718.3

such  counsel  or  the  Company,  upon  reasonable  advance  request,  any  documentation  or  information  which  is  not  privileged  or 
otherwise  protected  from  disclosure  and  which  is  reasonably  available  to  Indemnitee  and  reasonably  necessary  to  such 
determination.  The Company shall likewise cooperate with Indemnitee and Independent Counsel, if applicable, in making such 
determination with respect to Indemnitee’s entitlement to indemnification, including providing to such counsel and Indemnitee, 
upon  reasonable  advance  request,  any  documentation  or  information  which  is  not  privileged  or  otherwise  protected  from 
disclosure and which is reasonably available to the Company and reasonably necessary to such determination.  Any out-of-pocket 
costs or expenses (including reasonable attorneys’ fees and disbursements) actually and reasonably incurred by Indemnitee in so 
cooperating with the Independent Counsel or the Company shall be borne by the Company (irrespective of the determination as 
to  Indemnitee’s  entitlement  to  indemnification)  and  the  Company  hereby  indemnifies  and  agrees  to  hold  Indemnitee  harmless 
therefrom.

(b)       If the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to 
Section  10(a),  the  Independent  Counsel  shall  be  selected  by  the  Board  if  a  Change  in  Control  shall  not  have  occurred  or,  if  a 
Change in Control shall have occurred, by Indemnitee.  Indemnitee or the Company, as the case may be, may, within ten (10) 
days after written notice of such selection, deliver to the Company or Indemnitee, as the case may be, a written objection to such 
selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected 
does not meet the requirements of “Independent Counsel” as defined in Section 2 of this Agreement, and the objection shall set 
forth with particularity the factual basis of such assertion.  Absent a proper and timely objection, the person so selected shall act 
as Independent Counsel.  If such written objection is so made and substantiated, the Independent Counsel so selected may not 
serve  as  Independent  Counsel  unless  and  until  such  objection  is  withdrawn  or  the  Delaware  Court  has  determined  that  such 
objection is without merit.  If, within twenty (20) days after the later of (i) submission by Indemnitee of a written request for 
indemnification  pursuant  to  Section  9(a),  and  (ii)  the  final  disposition  of  the  Proceeding,  including  any  appeal  therein,  no 
Independent Counsel shall have been selected without objection, either Indemnitee or the Company may petition the Delaware 
Court for resolution of any objection which shall have been made by Indemnitee or the Company to the selection of Independent 
Counsel and/or for the appointment as Independent Counsel of a person selected by the court or by such other person as the court 
shall  designate.      The  person  with  respect  to  whom  all  objections  are  so  resolved  or  the  person  so  appointed  shall  act  as 
Independent  Counsel  under  Section  10(a)  hereof.    Upon  the  due  commencement  of  any  judicial  proceeding  or  arbitration 
pursuant to Section 12(a) of this Agreement, Independent Counsel shall be discharged and relieved of any further responsibility 
in such capacity (subject to the applicable standards of professional conduct then prevailing).

(c) Notwithstanding anything to the contrary contained in this Agreement, the determination of entitlement to 
indemnification  under  this  Agreement  shall  be  made  without  regard  to  the  Indemnitee’s  entitlement  to  and  availability  of 
insurance  coverage,  including  advancement,  payment  or  reimbursement  of  defense  costs,  expenses  or  covered  loss  under  the 
provisions  of  any  applicable  insurance  policy  (including,  without  limitation,  whether  such  advancement,  payment  or 
reimbursement is withheld, conditioned or delayed by the insurer(s)).

Section 11.     Presumptions and Effect of Certain Proceedings. 

(a)                To  the  extent  permitted  by  applicable  law,  in  making  a  determination  with  respect  to  entitlement  to 
indemnification hereunder, it shall be presumed that Indemnitee is entitled to indemnification under this Agreement if Indemnitee 
has submitted a request for indemnification in accordance with Section 9(a) of this Agreement, and the Company shall have the 
burden of proof and the burden of persuasion by clear and convincing evidence to overcome that presumption in connection with 
the making of any determination contrary to that presumption.  Neither (i) the failure of the Company or of Independent Counsel 
to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper 
in the 

ACTIVE/105004718.3

8

 
 
circumstances because Indemnitee has met the applicable standard of conduct, nor (ii) an actual determination by the Company 
or by Independent Counsel that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or 
create a presumption that Indemnitee has not met the applicable standard of conduct.

(b)              The  termination  of  any  Proceeding  or  of  any  claim,  issue  or  matter  therein,  by  judgment,  order, 
settlement  or  conviction,  or  upon  a  plea  of  guilty,  nolo  contendere  or  its  equivalent,  shall  not  (except  as  otherwise  expressly 
provided  in  this  Agreement)  of  itself  adversely  affect  the  right  of  Indemnitee  to  indemnification  or  create  a  presumption  that 
Indemnitee did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best 
interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that his or 
her conduct was unlawful.

(c)        Indemnitee shall be deemed to have acted in good faith if Indemnitee’s actions are based on the records 
or  books  of  account  of  the  Company  or  any  other  Enterprise,  including  financial  statements,  or  on  information  supplied  to 
Indemnitee by the directors, officers, agents or employees of the Company or any other Enterprise in the course of their duties, or 
on the advice of legal counsel for the Company or any other Enterprise or on information or records given or reports made to the 
Company or any other Enterprise by an independent certified public accountant or by an appraiser or other expert selected with 
reasonable care by the Company or any other Enterprise. The provisions of this Section 11(c) shall not be deemed to be exclusive 
or  to  limit  in  any  way  the  other  circumstances  in  which  Indemnitee  may  be  deemed  to  have  met  the  applicable  standard  of 
conduct set forth in this Agreement. In addition, the knowledge and/or actions, or failure to act, of any director, manager, partner, 
officer, employee, agent or trustee of the Company, any subsidiary of the Company, or any Enterprise shall not be imputed to 
Indemnitee  for  purposes  of  determining  the  right  to  indemnification  under  this  Agreement.  Whether  or  not  the  foregoing 
provisions of this Section 11(c) are satisfied, it shall in any event be presumed that Indemnitee has at all times acted in good faith 
and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company. Anyone seeking to 
overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence.

Section 12.      Remedies of Indemnitee.

(a)        Subject to Section 12(f), in the event that (i) a determination is made pursuant to Section 10 of this 
Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely 
made  pursuant  to  Section  8  of  this  Agreement,  (iii)  no  determination  of  entitlement  to  indemnification  shall  have  been  made 
pursuant  to  Section  10(a)  of  this  Agreement  within  sixty  (60)  days  after  receipt  by  the  Company  of  the  request  for 
indemnification for which a determination is to be made other than by Independent Counsel, (iv) payment of indemnification or 
reimbursement of expenses is not made pursuant to Section 5 or 6 or the last sentence of Section 10(a) of this Agreement within 
thirty (30) days after receipt by the Company of a written request therefor (including any invoices received by Indemnitee, which 
such invoices may be redacted as necessary to avoid the waiver of any privilege accorded by applicable law) or (v) payment of 
indemnification pursuant to Section 3 or 4 of this Agreement is not made within thirty (30) days after a determination has been 
made that Indemnitee is entitled to indemnification, Indemnitee shall be entitled to an adjudication by the Delaware Court of his 
or her entitlement to such indemnification or advancement.  Alternatively, Indemnitee, at his or her option, may seek an award in 
arbitration  to  be  conducted  by  a  single  arbitrator  pursuant  to  the  Commercial  Arbitration  Rules  of  the  American  Arbitration 
Association.    Indemnitee  shall  commence  such  proceeding  seeking  an  adjudication  or  an  award  in  arbitration  within  180  days 
following the date on which Indemnitee first has the right to commence such proceeding pursuant to this Section 12(a); provided, 
however, that the foregoing time limitation shall not apply in respect of a proceeding brought by Indemnitee to enforce his or her 
rights  under  Section  5  of  this  Agreement.  The  Company  shall  not  oppose  Indemnitee’s  right  to  seek  any  such  adjudication  or 
award in arbitration.

(b)       In the event that a determination shall have been made pursuant to Section 10(a) of this Agreement that 
Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 12 shall 
be conducted in all respects as a de novo trial, or arbitration, on the merits and Indemnitee shall not be prejudiced by reason of 
that adverse determination.  In any judicial proceeding or arbitration commenced pursuant to this Section 12, the Company shall 
have the burden of proving Indemnitee is not entitled to indemnification or advancement, as the case may be.

(c)        If a determination shall have been made pursuant to Section 10(a) of this Agreement that Indemnitee is 
entitled  to  indemnification,  the  Company  shall  be  bound  by  such  determination  in  any  judicial  proceeding  or  arbitration 
commenced pursuant to this Section 12, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material 
fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or 
(ii) a prohibition of such indemnification under applicable law.

(d)       The Company shall be precluded from asserting in any judicial proceeding or arbitration commenced 
pursuant to this Section 12 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and 
shall stipulate in any such court or before any such arbitrator that the Company is bound by all the provisions of this Agreement.  

(e)                The  Company  shall  indemnify  Indemnitee  to  the  fullest  extent  permitted  by  law  against  any  and  all 
Enforcement Expenses and, if requested by Indemnitee, shall (within thirty (30) days after receipt by the Company of a written 
request therefor) advance, to the extent not prohibited by law, such Enforcement Expenses to Indemnitee, which are incurred by 
Indemnitee in connection with any action brought by Indemnitee for indemnification or advancement from the Company under 
this Agreement or under any directors’ and officers’ liability insurance policies maintained by the Company in the suit for which 
indemnification  or  advancement  is  being  sought.    Such  written  request  for  advancement  shall  include  invoices  received  by 
Indemnitee  in  connection  with  such  Enforcement  Expenses  but,  in  the  case  of  invoices  in  connection  with  legal  services,  any 
references  to  legal  work  performed  or  to  expenditures  made  that  would  cause  Indemnitee  to  waive  any  privilege  accorded  by 
applicable law need not be included with the invoice.

(f)                Notwithstanding  anything  in  this  Agreement  to  the  contrary,  no  determination  as  to  entitlement  to 
indemnification under this Agreement shall be required to be made prior to the final disposition of the Proceeding, including any 
appeal therein.

Section 13.     Non-exclusivity; Survival of Rights; Insurance; Primacy of Indemnification; Subrogation.

(a)        The rights of indemnification and to receive advancement as provided by this Agreement shall not be 
deemed  exclusive  of  any  other  rights  to  which  Indemnitee  may  at  any  time  be  entitled  under  applicable  law,  the  Charter,  the 
Bylaws, any agreement, a vote of stockholders or a resolution of directors, or otherwise.  No amendment, alteration or repeal of 
this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any 
action taken or omitted by such Indemnitee in his or her Corporate Status prior to such amendment, alteration or repeal.  To the 
extent  that  a  change  in  Delaware  law,  whether  by  statute  or  judicial  decision,  permits  greater  indemnification  or  advancement 
than  would  be  afforded  currently  under  the  Charter,  Bylaws  and  this  Agreement,  it  is  the  intent  of  the  parties  hereto  that 
Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change.  No right or remedy herein conferred 
is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to 
every  other  right  and  remedy  given  hereunder  or  now  or  hereafter  existing  at  law  or  in  equity  or  otherwise.    The  assertion  or 
employment  of  any  right  or  remedy  hereunder,  or  otherwise,  shall  not  prevent  the  concurrent  assertion  or  employment  of  any 
other right or remedy.

(b)       To the extent that the Company maintains an insurance policy or policies providing liability insurance 
for directors, managers, partners, officers, employees, agents or trustees of the Company or of any other Enterprise, Indemnitee 
shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available 
for  any  such  director,  manager,  partner,  officer,  employee,  agent  or  trustee  under  such  policy  or  policies.  If,  at  the  time  of  the 
receipt of a notice of a claim pursuant to the terms hereof, the Company has director and officer liability insurance in effect, the 
Company  shall  give  prompt  notice  of  such  claim  to  the  insurers  in  accordance  with  the  procedures  set  forth  in  the  respective 
policies.    The  Company  shall  thereafter  take  all  necessary  or  desirable  action  to  cause  such  insurers  to  pay,  on  behalf  of  the 
Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such policies. Upon request of 
Indemnitee,  the  Company  shall  also  promptly  provide  to  Indemnitee:  (i)  copies  of  all  of  the  Company’s  potentially  applicable 
directors’ and officers’ liability insurance policies, (ii) copies of such notices delivered to the applicable insurers, and (iii) copies 
of all subsequent communications and correspondence between the Company and such insurers regarding the Proceeding. 

(c)        [The Company hereby acknowledges that Indemnitee has certain rights to indemnification, advancement 
of  expenses  and/or  insurance  provided  by  [      ]  and  certain  of  its  affiliates  (collectively,  the  “Secondary  Indemnitors”).    The 
Company  hereby  agrees  (i)  that  it  is  the  indemnitor  of  first  resort  (i.e.,  its  obligations  to  Indemnitee  are  primary  and  any 
obligation of the Secondary Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities 
incurred  by  Indemnitee  are  secondary),  (ii)  that  it  shall  be  required  to  advance  the  full  amount  of  expenses  incurred  by 
Indemnitee and shall be liable for the full amount of all Expenses, judgments, penalties, fines and amounts paid in settlement to 
the  extent  legally  permitted  and  as  required  by  the  terms  of  this  Agreement  and  the  Charter  and/or  Bylaws  (or  any  other 
agreement  between  the  Company  and  Indemnitee),  without  regard  to  any  rights  Indemnitee  may  have  against  the  Secondary 
Indemnitors,  and  (iii)  that  it  irrevocably  waives,  relinquishes  and  releases  the  Secondary  Indemnitors  from  any  and  all  claims 
against  the  Secondary  Indemnitors  for  contribution,  subrogation  or  any  other  recovery  of  any  kind  in  respect  thereof.    The 
Company further agrees that no advancement or payment by the Secondary Indemnitors on behalf of Indemnitee with respect to 
any  claim  for  which  Indemnitee  has  sought  indemnification  from  the  Company  shall  affect  the  foregoing  and  the  Secondary 
Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the 
rights of recovery of Indemnitee against the Company.  The Company and Indemnitee agree that the Secondary Indemnitors are 
express third party beneficiaries of the terms of this Section 13(c).]

(d)       [Except as provided in paragraph (c) above,] in the event of any payment under this Agreement, the 
Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee [(other than against the 
Secondary  Indemnitors)],  who  shall  execute  all  papers  required  and  take  all  action  necessary  to  secure  such  rights,  including 
execution of such documents as are necessary to enable the Company to bring suit to enforce such rights.

(e)        [Except as provided in paragraph (c) above,] the Company’s obligation to provide indemnification or 
advancement  hereunder  to  Indemnitee  who  is  or  was  serving  at  the  request  of  the  Company  as  a  director,  manager,  partner, 
officer, employee, agent or trustee of any other Enterprise shall be reduced by any amount Indemnitee has actually received as 
indemnification or advancement from such other Enterprise.

Section 14.       Duration of Agreement.  This Agreement shall continue until and terminate upon the later of: (a) ten (10) 
years after the date that Indemnitee shall have ceased to serve as a director of the Company or (b) one (1) year after the final 
termination  of  any  Proceeding,  including  any  appeal,  then  pending  in  respect  of  which  Indemnitee  is  granted  rights  of 
indemnification  or  advancement  hereunder  and  of  any  proceeding  commenced  by  Indemnitee  pursuant  to  Section  12  of  this 
Agreement relating thereto. This Agreement shall be binding upon the Company and its successors and assigns and shall inure to 
the benefit of Indemnitee and his or her heirs, executors 

ACTIVE/105004718.3

and  administrators.    The  Company  shall  require  and  cause  any  successor  (whether  direct  or  indirect  by  purchase,  merger, 
consolidation or otherwise) to all, substantially all or a substantial part, of the business and/or assets of the Company, by written 
agreement  in  form  and  substance  satisfactory  to  Indemnitee,  expressly  to  assume  and  agree  to  perform  this  Agreement  in  the 
same manner and to the same extent that the Company would be required to perform if no such succession had taken place.

Section  15.            Severability.    If  any  provision  or  provisions  of  this  Agreement  shall  be  held  to  be  invalid,  illegal  or 
unenforceable  for  any  reason  whatsoever:  (a)  the  validity,  legality  and  enforceability  of  the  remaining  provisions  of  this 
Agreement (including, without limitation, each portion of any section of this Agreement containing any such provision held to be 
invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired 
thereby  and  shall  remain  enforceable  to  the  fullest  extent  permitted  by  law;  (b)  such  provision  or  provisions  shall  be  deemed 
reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; 
and (c) to the fullest extent possible, the provisions of this Agreement (including, without limitation, each portion of any section 
of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or 
unenforceable) shall be construed so as to give effect to the intent manifested thereby.

Section 16.      Enforcement.

(a)        The Company expressly confirms and agrees that it has entered into this Agreement and assumed the 
obligations imposed on it hereby in order to induce Indemnitee to serve or continue to serve as a director of the Company, and the 
Company acknowledges that Indemnitee is relying upon this Agreement in serving as a director of the Company.

(b)       This Agreement constitutes the entire agreement between the parties hereto with respect to the subject 
matter hereof and supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with 
respect to the subject matter hereof; provided, however, that this Agreement is a supplement to and in furtherance of the Charter, 
the Bylaws and applicable law, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee 
thereunder.

Section 17.      Modification and Waiver.  No supplement, modification or amendment, or waiver of any provision, of 
this  Agreement  shall  be  binding  unless  executed  in  writing  by  the  parties  thereto.    No  waiver  of  any  of  the  provisions  of  this 
Agreement shall be deemed or shall constitute a waiver of any other provisions of this Agreement nor shall any waiver constitute 
a  continuing  waiver.  No  supplement,  modification  or  amendment  of  this  Agreement  or  of  any  provision  hereof  shall  limit  or 
restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee prior to such 
supplement, modification or amendment.

matter  which  may  be  subject  to  indemnification,  reimbursement  or  advancement  as  provided  hereunder.    The  failure  of 
Indemnitee to so notify the Company or any delay in notification shall not relieve the Company of any obligation which it may 
have to Indemnitee under this Agreement or otherwise. unless, and then only to the extent that, the Company did not otherwise 
learn of the Proceeding and such delay is materially prejudicial to the Company’s ability to defend such Proceeding or matter; 
and, provided, further, that notice will be deemed to have been given without any action on the part of Indemnitee in the event the 
Company is a party to the same Proceeding.

Section  19.            Notices.    All  notices,  requests,  demands  and  other  communications  under  this  Agreement  shall  be  in 

writing and shall be deemed to have been duly given if (i) delivered by hand and receipted for by the

party  to  whom  said  notice  or  other  communication  shall  have  been  directed,  (ii)  mailed  by  certified  or  registered  mail  with 
postage prepaid, on the third business day after the date on which it is so mailed, (iii) mailed by reputable overnight courier and 
receipted  for  by  the  party  to  whom  said  notice  or  other  communication  shall  have  been  directed  or  (iv)  sent  by  facsimile 
transmission, with receipt of oral confirmation that such transmission has been received:

(a)        If to Indemnitee, at such address as Indemnitee shall provide to the Company.

or to any other address as may have been furnished to Indemnitee by the Company.

Section 20.      Contribution.  To the fullest extent permissible under applicable law, if the indemnification provided for 
in  this  Agreement  is  unavailable  to  Indemnitee  for  any  reason  whatsoever,  the  Company,  in  lieu  of  indemnifying  Indemnitee, 
shall contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to 
be paid in settlement and/or for Expenses, in connection with any Proceeding in such proportion as is deemed fair and reasonable 
in  light  of  all  of  the  circumstances  in  order  to  reflect  (i)  the  relative  benefits  received  by  the  Company  and  Indemnitee  in 
connection with the event(s) and/or transaction(s) giving rise to such Proceeding; and/or (ii) the relative fault of the Company 
(and its directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transactions.

Section  21.            Internal  Revenue  Code  Section  409A.    The  Company  intends  for  this  Agreement  to  comply  with  the 
Indemnification  exception  under  Section  1.409A-1(b)(10)  of  the  regulations  promulgated  under  the  Internal  Revenue  Code  of 
1986,  as  amended  (the  “Code”),  which  provides  that  indemnification  of,  or  the  purchase  of  an  insurance  policy  providing  for 
payments of, all or part of the expenses incurred or damages paid or payable by Indemnitee with respect to a bona fide claim 
against Indemnitee or the Company do not provide for a deferral of compensation, subject to Section 409A of the Code, where 
such claim is based on actions or failures to act by Indemnitee in his or her capacity as a service provider of the Company.  The 
parties intend that this Agreement be interpreted and construed with such intent.

Section 22.      Applicable Law and Consent to Jurisdiction.  This Agreement and the legal relations among the parties 
shall be governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without regard to its 
conflict  of  laws  rules.  Except  with  respect  to  any  arbitration  commenced  by  Indemnitee  pursuant  to  Section  12(a)  of  this 
Agreement, the Company and Indemnitee hereby irrevocably and unconditionally (i) agree that any action or proceeding arising 
out of or in connection with this Agreement shall be brought only in the Delaware Court, and not in any other state or federal 
court in the United States of America or any court in any other country, (ii) consent to submit to the exclusive jurisdiction of the 
Delaware  Court  for  purposes  of  any  action  or  proceeding  arising  out  of  or  in  connection  with  this  Agreement,  (iii)  consent  to 
service of process at the address set forth in Section 19 of this Agreement with the same legal force and validity as if served upon 
such  party  personally  within  the  State  of  Delaware,  (iv)  waive  any  objection  to  the  laying  of  venue  of  any  such  action  or 
proceeding in the Delaware Court, and (v) waive, and agree not to plead or to make, any claim that any such action or proceeding 
brought in the Delaware Court has been brought in an improper or inconvenient forum.

Section 23.      Headings.  The headings of the paragraphs of this Agreement are inserted for convenience only and shall 

not be deemed to constitute part of this Agreement or to affect the construction thereof.

Section 24.      Identical Counterparts.  This Agreement may be executed in one or more counterparts, each of which 
shall for all purposes be deemed to be an original but all of which together shall constitute one and the same Agreement.  Only 
one such counterpart signed by the party against whom enforceability is sought needs to be produced to evidence the existence of 
this Agreement.

Section  25.            Monetary  Damages  Insufficient/Specific  Enforcement.  The  Company  and  Indemnitee  agree  that  a 
monetary remedy for breach of this Agreement may be inadequate, impracticable and difficult of proof, and further agree that 
such  breach  may  cause  Indemnitee  irreparable  harm.  Accordingly,  the  parties  hereto  agree  that  Indemnitee  may  enforce  this 
Agreement by seeking injunctive relief and/or specific performance hereof, without any necessity of showing actual damage or 
irreparable harm (having agreed that actual and irreparable harm will result in not forcing the Company to specifically perform its 
obligations pursuant to this Agreement) and that by seeking injunctive relief and/or specific performance, Indemnitee shall not be 
precluded from seeking or obtaining any other relief to which he may be entitled. The Company and Indemnitee further agree 
that  Indemnitee  shall  be  entitled  to  such  specific  performance  and  injunctive  relief,  including  temporary  restraining  orders, 
preliminary  injunctions  and  permanent  injunctions,  without  the  necessity  of  posting  bonds  or  other  undertaking  in  connection 
therewith. The Company acknowledges that in the absence of a waiver, a bond or undertaking may be required of Indemnitee by 
the Court, and the Company hereby waives any such requirement of a bond or undertaking.

FORM OF OFFICER INDEMNIFICATION AGREEMENT

This Indemnification Agreement (“Agreement”) is made as of [________________] by and between Adicet Bio, Inc., a 

Delaware corporation (the “Company”), and [Officer] (“Indemnitee”).1

RECITALS

WHEREAS, the Company desires to attract and retain the services of highly qualified individuals, such as Indemnitee, to 

serve the Company;

WHEREAS,  in  order  to  induce  Indemnitee  to  provide  or  continue  to  provide  services  to  the  Company,  the  Company 
wishes to provide for the indemnification of, and advancement of expenses to, Indemnitee to the maximum extent permitted by 
law;

WHEREAS, the Third Amended and Restated Certificate of Incorporation (as amended and in effect from time to time, 
the  “Charter”)  and  the  Amended  and  Restated  Bylaws  (as  amended  and  in  effect  from  time  to  time,  the  “Bylaws”)  of  the 
Company  require  indemnification  of  the  officers  and  directors  of  the  Company,  and  Indemnitee  may  also  be  entitled  to 
indemnification pursuant to the General Corporation Law of the State of Delaware (the “DGCL”); 

WHEREAS,  the  Charter,  the  Bylaws  and  the  DGCL  expressly  provide  that  the  indemnification  provisions  set  forth 
therein are not exclusive, and thereby contemplate that contracts may be entered into between the Company and members of the 
board of directors, officers and other persons with respect to indemnification;

WHEREAS,  the  Board  of  Directors  of  the  Company  (the  “Board”)  has  determined  that  the  increased  difficulty  in 
attracting  and  retaining  highly  qualified  persons  such  as  Indemnitee  is  detrimental  to  the  best  interests  of  the  Company’s 
stockholders;

WHEREAS, it is reasonable and prudent for the Company contractually to obligate itself to indemnify, and to advance 
expenses on behalf of, such persons to the fullest extent permitted by applicable law, regardless of any amendment or revocation 
of the Charter or the Bylaws, so that they will serve or continue to serve the Company free from undue concern that they will not 
be so indemnified; and

WHEREAS, this Agreement is a supplement to and in furtherance of the indemnification provided in the Charter, the 
Bylaws and any resolutions adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate 
any rights of Indemnitee thereunder.

NOW, THEREFORE, in consideration of the premises and the covenants contained herein, the Company and Indemnitee 

do hereby covenant and agree as follows:

1 To be entered into with all C-level officers and Section 16 officers.

Company.    Indemnitee  may  at  any  time  and  for  any  reason  resign  from  [any]  such  position  (subject  to  any  other  contractual 
obligation  or  any  obligation  imposed  by  law),  in  which  event  the  Company  shall  have  no  obligation  under  this  Agreement  to 
continue Indemnitee in such position.  This Agreement shall not be deemed an employment contract between the Company (or 
any of its subsidiaries or any Enterprise) and Indemnitee.

or more conditions (whether or not within the control of such Person) or otherwise) upon the exercise of any conversion 
rights,  exchange  rights,  rights,  warrants  or  options,  or  otherwise;  (B)  the  right  to  vote  pursuant  to  any  agreement, 
arrangement  or  understanding  (whether  or  not  in  writing);  or  (C)  the  right  to  dispose  of  pursuant  to  any  agreement,

Stock by a Qualified Stockholder (as defined in the Charter))] unless the change in relative Beneficial Ownership of the 
Company’s  securities  by  any  Person  results  solely  from  a  reduction  in  the  aggregate  number  of  outstanding  shares  of 
securities entitled to vote generally in the election of directors [or as a result of conversions of Class B Common Stock], 
provided  that  a  Change  of  Control  shall  be  deemed  to  have  occurred  if  subsequent  to  such  reduction  such  Person 
becomes the Beneficial Owner, directly or indirectly, of any additional securities of the Company conferring upon such 
Person any additional voting power;

agreement with the Company to effect a transaction described in Sections 2(c)(i), 2(c)(iii) or 2(c)(iv) whose election by 
the Board or nomination for election by the Company’s stockholders was approved by a vote of at least two-thirds of the

power  of  the  voting  securities  of  the  surviving  or  successor  entity  outstanding  immediately  after  such  merger  or 
consolidation and with the power to elect at least a majority of the board of directors or other governing body of such 
surviving or successor entity;

related transactions, of all or substantially all of the Company’s assets; and

(v)  Other  Events.  There  occurs  any  other  event  of  a  nature  that  would  be  required  to  be 
reported in response to Item 6(e) of Schedule 14A of Regulation 14A (or a response to any similar item on any similar

indemnification hereunder.  Notwithstanding the foregoing, the term “Independent Counsel” shall not include any person 
who,  under  the  applicable  standards  of  professional  conduct  then  prevailing,  would  have  a  conflict  of  interest  in

or is or was serving at the

request of the Company as a director, manager, partner, officer, employee, agent or trustee of any Enterprise or by reason 
of any action taken by Indemnitee or of any action taken on his or her part while acting as [a director or] an officer of the 
Company  or  while  serving  at  the  request  of  the  Company  as  a  director,  manager,  partner,  officer,  employee,  agent  or 
trustee  of  any  Enterprise,  in  each  case  whether  or  not  serving  in  such  capacity  at  the  time  any  liability  or  expense  is 
incurred for which indemnification, reimbursement or advancement of expenses can be provided under this Agreement; 
provided, however, that the term “Proceeding” shall not include any action, suit or arbitration, or part thereof, initiated 
by Indemnitee to enforce Indemnitee’s rights under this Agreement as provided for in Section 12(a) of this Agreement.

Section 3.        Indemnity in Third-Party Proceedings.  The Company shall indemnify Indemnitee to the extent set forth 
in  this  Section  3  if  Indemnitee  is,  or  is  threatened  to  be  made,  a  party  to  or  a  participant  in  any  Proceeding,  other  than  a 
Proceeding by or in the right of the Company to procure a judgment in its favor.  Pursuant to this Section 3, Indemnitee shall be 
indemnified  against  all  Expenses,  judgments,  fines,  penalties,  excise  taxes,  and  amounts  paid  in  settlement  actually  and 
reasonably  incurred  by  Indemnitee  or  on  his  or  her  behalf  in  connection  with  such  Proceeding  or  any  claim,  issue  or  matter 
therein,  if  Indemnitee  acted  in  good  faith  and  in  a  manner  he  or  she  reasonably  believed  to  be  in  or  not  opposed  to  the  best 
interests of the Company and, in the case of a criminal proceeding, had no reasonable cause to believe that his or her conduct was 
unlawful.  

Section 4.        Indemnity in Proceedings by or in the Right of the Company.  The Company shall indemnify Indemnitee 
to the extent set forth in this Section 4 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding 
by or in the right of the Company to procure a judgment in its favor.  Pursuant to this Section 4, Indemnitee shall be indemnified 
against all Expenses actually and reasonably incurred by Indemnitee or on his or her behalf in connection with such Proceeding 
or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner he or she reasonably believed to be in or 
not opposed to the best interests of the Company.  No indemnification for Expenses shall be made under this Section 4 in respect 
of any claim, issue or matter as to which Indemnitee shall have been finally adjudged by a court to be liable to the Company, 
unless and only to the extent that the Delaware Court of Chancery (the “Delaware Court”) shall determine upon application that, 
despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to 
indemnification for such expenses as the Delaware Court shall deem proper.

Section 5.        Indemnification for Expenses of a Party Who is Wholly or Partly Successful.  Notwithstanding any other 
provisions of this Agreement and except as provided in Section 7, to the extent that Indemnitee is a party to or a participant in 
any  Proceeding  and  is  successful  in  such  Proceeding  or  in  defense  of  any  claim,  issue  or  matter  therein,  the  Company  shall 
indemnify  Indemnitee  against  all  Expenses  actually  and  reasonably  incurred  by  him  or  her  in  connection  therewith.    If 
Indemnitee  is  not  wholly  successful  in  such  Proceeding  but  is  successful  as  to  one  or  more  but  less  than  all  claims,  issues  or 
matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by 
Indemnitee  or  on  his  or  her  behalf  in  connection  with  each  successfully  resolved  claim,  issue  or  matter.    For  purposes  of  this 
Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without 
prejudice, shall be deemed to be a successful result as to such claim, issue or matter.

Section 6.        Reimbursement for Expenses of a Witness or in Response to a Subpoena.  Notwithstanding  any  other 
provision  of  this  Agreement,  to  the  extent  that  Indemnitee,  by  reason  of  his  or  her  Corporate  Status,  (i)  is  a  witness  in  any 
Proceeding to which Indemnitee is not a party and is not threatened to be made a party or (ii) receives a subpoena with respect to 
any Proceeding to which Indemnitee is not a party and is not threatened to be

made a party, the Company shall reimburse Indemnitee for all Expenses actually and reasonably incurred by him or her or on his 
or her behalf in connection therewith.   

Section 7.        Exclusions.  Notwithstanding any provision in this Agreement to the contrary, the Company shall not be 

obligated under this Agreement:  

(a)              to  indemnify  for  amounts  otherwise  indemnifiable  hereunder  (or  for  which  advancement  is  provided 
hereunder)  if  and  to  the  extent  that  Indemnitee  has  otherwise  actually  received  such  amounts  under  any  insurance  policy, 
contract, agreement or otherwise; provided that the foregoing shall not [i] apply to any personal or umbrella liability insurance 
maintained by Indemnitee, [or (ii) affect the rights of Indemnitee or the Fund Indemnitors as set forth in Section 13(c)];

(b)       to indemnify for an accounting of profits made from the purchase and sale (or sale and purchase) by 
Indemnitee  of  securities  of  the  Company  within  the  meaning  of  Section  16(b)  of  the  Securities  Exchange  Act  of  1934,  as 
amended,  or  similar  provisions  of  state  statutory  law  or  common  law,  or  from  the  purchase  or  sale  by  Indemnitee  of  such 
securities in violation of Section 306 of the Sarbanes-Oxley Act of 2002 (“SOX”);

(c)       to indemnify for any reimbursement of, or payment to, the Company by Indemnitee of any bonus or 
other  incentive-based  or  equity-based  compensation  or  of  any  profits  realized  by  Indemnitee  from  the  sale  of  securities  of  the 
Company pursuant to Section 304 of SOX or any formal policy of the Company adopted by the Board (or a committee thereof), 
or any other remuneration paid to Indemnitee if it shall be determined by a final judgment or other final adjudication that such 
remuneration was in violation of law; 

(d)              to  indemnify  with  respect  to  any  Proceeding,  or  part  thereof,  brought  by  Indemnitee  against  the 
Company, any legal entity which it controls, any director or officer thereof or any third party, unless (i) the Board has consented 
to  the  initiation  of  such  Proceeding  or  part  thereof  and  (ii)  the  Company  provides  the  indemnification,  in  its  sole  discretion, 
pursuant to the powers vested in the Company under applicable law; provided, however, that this Section 7(d) shall not apply to 
(A)  counterclaims  or  affirmative  defenses  asserted  by  Indemnitee  in  an  action  brought  against  Indemnitee  or  (B)  any  action 
brought by Indemnitee for indemnification or advancement from the Company under this Agreement or under any directors’ and 
officers’ liability insurance policies maintained by the Company in the suit for which indemnification or advancement is being 
sought as described in Section 12; or

law exists at the time payment would otherwise be required pursuant to this Agreement).

(e)       to provide any indemnification or advancement of expenses that is prohibited by applicable law (as such 

Section 8.        Advancement of Expenses.  Subject to Section 9(b), the Company shall advance the Expenses incurred by 
Indemnitee in connection with any Proceeding, and such advancement shall be made as incurred, and such advancement shall be 
made within thirty (30) days after the receipt by the Company of a statement or statements requesting such advances (including 
any  invoices  received  by  Indemnitee,  which  such  invoices  may  be  redacted  as  necessary  to  avoid  the  waiver  of  any  privilege 
accorded by applicable law) from time to time, whether prior to or after final disposition of any Proceeding.  Advances shall be 
unsecured and interest free.  Advances shall be made without regard to Indemnitee’s (i) ability to repay the expenses, (ii) ultimate 
entitlement to indemnification under the other provisions of this Agreement, and (iii) entitlement to and availability of insurance 
coverage, including advancement, payment or reimbursement of defense costs, expenses of covered loss under the provisions of 
any  applicable  insurance  policy  (including  ,  without  limitation,  whether  such  advancement,  payment  or  reimbursement  is 
withheld, conditioned or delayed by the insurer(s)). Indemnitee shall qualify for advances upon the execution and delivery to the 
Company of this Agreement which shall

constitute an undertaking providing that Indemnitee undertakes to the fullest extent required by law to repay the advance if and to 
the  extent  that  it  is  ultimately  determined  by  a  court  of  competent  jurisdiction  in  a  final  judgment,  not  subject  to  appeal,  that 
Indemnitee  is  not  entitled  to  be  indemnified  by  the  Company.  No  other  form  of  undertaking  shall  be  required.  The  right  to 
advances under this paragraph shall in all events continue until final disposition of any Proceeding, including any appeal therein.  
Nothing in this Section 8 shall limit Indemnitee’s right to advancement pursuant to Section 12(e) of this Agreement. 

Section 9.       Procedure for Notification and Defense of Claim.

(a)              To  obtain  indemnification  under  this  Agreement,  Indemnitee  shall  submit  to  the  Company  a  written 
request therefor specifying the basis for the claim, the amounts for which Indemnitee is seeking payment under this Agreement, 
and all documentation related thereto as reasonably requested by the Company.  

(b)       In the event that the Company shall be obligated hereunder to provide indemnification for or make any 
advancement  of  Expenses  with  respect  to  any  Proceeding,  the  Company  shall  be  entitled  to  assume  the  defense  of  such 
Proceeding,  or  any  claim,  issue  or  matter  therein,  with  counsel  approved  by  Indemnitee  (which  approval  shall  not  be 
unreasonably withheld or delayed) upon the delivery to Indemnitee of written notice of the Company’s election to do so.  After 
delivery of such notice, approval of such counsel by Indemnitee and the retention of such counsel by the Company, the Company 
will not be liable to Indemnitee under this Agreement for any fees or expenses of separate counsel subsequently employed by or 
on behalf of Indemnitee with respect to the same Proceeding; provided that (i) Indemnitee shall have the right to employ separate 
counsel in any such Proceeding at Indemnitee’s expense and (ii) if (A) the employment of separate counsel by Indemnitee has 
been  previously  authorized  by  the  Company,  (B)  Indemnitee  shall  have  reasonably  concluded  that  there  may  be  a  conflict  of 
interest between the Company and Indemnitee in the conduct of such defense, (C) the Company shall not continue to retain such 
counsel  to  defend  such  Proceeding,  or  (D)  a  Change  in  Control  shall  have  occurred,  then  the  fees  and  expenses  actually  and 
reasonably incurred by Indemnitee with respect to his or her separate counsel shall be Expenses hereunder.  

above, then the Company will be entitled to participate in the Proceeding at its own expense.

(c)       In the event that the Company does not assume the defense in a Proceeding pursuant to paragraph (b) 

(d)       The Company shall not be liable to indemnify Indemnitee under this Agreement for any amounts paid in 
settlement  of  any  Proceeding  effected  without  its  prior  written  consent  (which  consent  shall  not  be  unreasonably  withheld  or 
delayed).  The  Company  shall  not,  without  the  prior  written  consent  of  Indemnitee  (which  consent  shall  not  be  unreasonably 
withheld or delayed), enter into any settlement which (i) includes an admission of fault of Indemnitee, any non-monetary remedy 
imposed on Indemnitee or any monetary damages for which Indemnitee is not wholly and actually indemnified hereunder or (ii) 
with respect to any Proceeding with respect to which Indemnitee may be or is made a party or may be otherwise entitled to seek 
indemnification hereunder, does not include the full release of Indemnitee from all liability in respect of such Proceeding.

Section 10.      Procedure Upon Application for Indemnification.2

(a)        Upon written request by Indemnitee for indemnification pursuant to Section 9(a), a determination, if 
such determination is required by applicable law, with respect to Indemnitee’s entitlement to indemnification hereunder shall be 
made in the specific case by one of the following methods: [(x) if a Change in Control shall have occurred and indemnification is 
being requested by Indemnitee hereunder in his or her capacity as a director of the Company, by Independent Counsel in a written 
opinion  to  the  Board;  or  (y)  in  any  other  case,]  (i)  by  a  majority  vote  of  the  disinterested  directors,  even  though  less  than  a 
quorum; (ii) by a committee of disinterested directors designated by a majority vote of the disinterested directors, even though 
less than a quorum; or (iii) if there are no disinterested directors or if the disinterested directors so direct, by Independent Counsel 
in a written opinion to the Board.  For purposes hereof, disinterested directors are those members of the Board who are not parties 
to the action, suit or proceeding in respect of which indemnification is sought.  In the case that such determination is made by 
Independent Counsel, a copy of Independent Counsel’s written opinion shall be delivered to Indemnitee and, if it is so determined 
that  Indemnitee  is  entitled  to  indemnification,  payment  to  Indemnitee  shall  be  made  within  thirty  (30)  days  after  such 
determination.  Indemnitee  shall  cooperate  with  the  Independent  Counsel  or  the  Company,  as  applicable,  in  making  such 
determination with respect to Indemnitee’s entitlement to indemnification, including providing to such counsel or the Company, 
upon  reasonable  advance  request,  any  documentation  or  information  which  is  not  privileged  or  otherwise  protected  from 
disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination.  The Company shall 
likewise  cooperate  with  Indemnitee  and  Independent  Counsel,  if  applicable,  in  making  such  determination  with  respect  to 
Indemnitee’s  entitlement  to  indemnification,  including  providing  to  such  counsel  and  Indemnitee,  upon  reasonable  advance 
request,  any  documentation  or  information  which  is  not  privileged  or  otherwise  protected  from  disclosure  and  which  is 
reasonably  available  to  the  Company  and  reasonably  necessary  to  such  determination.  Any  out-of-pocket  costs  or  expenses 
(including reasonable attorneys’ fees and disbursements) actually and reasonably incurred by Indemnitee in so cooperating with 
the Independent Counsel or the Company shall be borne by the Company (irrespective of the determination as to Indemnitee’s 
entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom.

(b)       If the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to 
Section 10(a), the Independent Counsel shall be selected by the Board[; provided that, if a Change in Control shall have occurred 
and  indemnification  is  being  requested  by  Indemnitee  hereunder  in  his  or  her  capacity  as  a  director  of  the  Company,  the 
Independent Counsel shall be selected by Indemnitee].  Indemnitee [or the Company, as the case may be,] may, within ten (10) 
days after written notice of such selection, deliver to the Company [or Indemnitee, as the case may be,] a written objection to 
such  selection;  provided,  however,  that  such  objection  may  be  asserted  only  on  the  ground  that  the  Independent  Counsel  so 
selected does not meet the requirements of “Independent Counsel” as defined in Section 2 of this Agreement, and the objection 
shall set forth with particularity the factual basis of such assertion.  Absent a proper and timely objection, the person so selected 
shall act as Independent Counsel.  If such written objection is so made and substantiated, the Independent Counsel so selected 
may not serve as Independent Counsel unless and until such objection is withdrawn or the Delaware Court has determined that 
such objection is without merit.  If, within twenty (20) days after the later of (i) submission by Indemnitee of a written request for 
indemnification  pursuant  to  Section  9(a),  and  (ii)  the  final  disposition  of  the  Proceeding,  including  any  appeal  therein,  no 
Independent Counsel shall have been selected without objection, either Indemnitee or the Company may petition the Delaware 
Court for resolution of any objection which shall have been made by Indemnitee or the Company to the selection of Independent 
Counsel and/or for the appointment as Independent Counsel of a person selected by the court or by such other person as the court 
shall  designate.    The  person  with  respect  to  whom  all  objections  are  so  resolved  or  the  person  so  appointed  shall  act  as 
Independent  Counsel  under  Section  10(a)  hereof.    Upon  the  due  commencement  of  any  judicial  proceeding  or  arbitration 
pursuant to Section 12(a) of this Agreement, Independent Counsel shall be discharged and relieved of any further responsibility 
in such capacity (subject to the applicable standards of professional conduct then prevailing).

(c)        Notwithstanding anything to the contrary contained in this Agreement, the determination of entitlement 
to  indemnification  under  this  Agreement  shall  be  made  without  regard  to  the  Indemnitee’s  entitlement  to  and  availability  of 
insurance  coverage,  including  advancement,  payment  or  reimbursement  of  defense  costs,  expenses  or  covered  loss  under  the 
provisions  of  any  applicable  insurance  policy  (including,  without  limitation,  whether  such  advancement,  payment  or 
reimbursement is withheld, conditioned or delayed by the insurer(s)).

Section 11.     Presumptions and Effect of Certain Proceedings. 

(a)              To  the  extent  permitted  by  applicable  law,  in  making  a  determination  with  respect  to  entitlement  to 
indemnification hereunder, it shall be presumed that Indemnitee is entitled to indemnification under this Agreement if Indemnitee 
has submitted a request for indemnification in accordance with Section 9(a) of this Agreement, and the Company shall have the 
burden of proof and the burden of persuasion by clear and convincing evidence to overcome that presumption in connection with 
the making of any determination contrary to that presumption.  Neither (i) the failure of the Company or of Independent Counsel 
to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper 
in  the  circumstances  because  Indemnitee  has  met  the  applicable  standard  of  conduct,  nor  (ii)  an  actual  determination  by  the 
Company or by Independent Counsel that Indemnitee has not met such applicable standard of conduct, shall be a defense to the 
action or create a presumption that Indemnitee has not met the applicable standard of conduct.

(b)              The  termination  of  any  Proceeding  or  of  any  claim,  issue  or  matter  therein,  by  judgment,  order, 
settlement  or  conviction,  or  upon  a  plea  of  guilty,  nolo  contendere  or  its  equivalent,  shall  not  (except  as  otherwise  expressly 
provided  in  this  Agreement)  of  itself  adversely  affect  the  right  of  Indemnitee  to  indemnification  or  create  a  presumption  that 
Indemnitee did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best 
interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that his or 
her conduct was unlawful.

ACTIVE/105005427.2

(c)        Indemnitee shall be deemed to have acted in good faith if Indemnitee’s actions are based on the records 
or  books  of  account  of  the  Company  or  any  other  Enterprise,  including  financial  statements,  or  on  information  supplied  to 
Indemnitee by the directors, officers, agents or employees of the Company or any other Enterprise in the course of their duties, or 
on the advice of legal counsel for the Company or any other Enterprise or on information or records given or reports made to the 
Company or any other Enterprise by an independent certified public accountant or by an appraiser or other expert selected with 
reasonable care by the Company or any other Enterprise. The provisions of this Section 11(c) shall not be deemed to be exclusive 
or  to  limit  in  any  way  the  other  circumstances  in  which  Indemnitee  may  be  deemed  to  have  met  the  applicable  standard  of 
conduct set forth in this Agreement. In addition, the knowledge and/or actions, or failure to act, of any director, manager, partner, 
officer, employee, agent or trustee of the Company, any subsidiary of the Company, or any Enterprise shall not be imputed to 
Indemnitee  for  purposes  of  determining  the  right  to  indemnification  under  this  Agreement.  Whether  or  not  the  foregoing 
provisions of this Section 11(c) are satisfied, it shall in any event be presumed that Indemnitee has at all times acted in good faith 
and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company. Anyone seeking to 
overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence.

Section 12.      Remedies of Indemnitee.

(a)        Subject to Section 12(f), in the event that (i) a determination is made pursuant to Section 10 of this 
Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely 
made  pursuant  to  Section  8  of  this  Agreement,  (iii)  no  determination  of  entitlement  to  indemnification  shall  have  been  made 
pursuant  to  Section  10(a)  of  this  Agreement  within  sixty  (60)  days  after  receipt  by  the  Company  of  the  request  for 
indemnification for which a determination is to be made other than by Independent Counsel, (iv) payment of indemnification or 
reimbursement of expenses is not made pursuant to Section 5 or 6 or the last sentence of Section 10(a) of this Agreement within 
thirty (30) days after receipt by the Company of a written request therefor (including any invoices received by Indemnitee, which 
such invoices may be redacted as necessary to avoid the waiver of any privilege accorded by applicable law) or (v) payment of 
indemnification pursuant to Section 3 or 4 of this Agreement is not made within thirty (30) days after a determination has been 
made that Indemnitee is entitled to indemnification, Indemnitee shall be entitled to an adjudication by the Delaware Court of his 
or her entitlement to such indemnification or advancement.  Alternatively, Indemnitee, at his or her option, may seek an award in 
arbitration  to  be  conducted  by  a  single  arbitrator  pursuant  to  the  Commercial  Arbitration  Rules  of  the  American  Arbitration 
Association.    Indemnitee  shall  commence  such  proceeding  seeking  an  adjudication  or  an  award  in  arbitration  within  180  days 
following the date on which Indemnitee first has the right to commence such proceeding pursuant to this Section 12(a); provided, 
however, that the foregoing time limitation shall not apply in respect of a proceeding brought by Indemnitee to enforce his or her 
rights  under  Section  5  of  this  Agreement.  The  Company  shall  not  oppose  Indemnitee’s  right  to  seek  any  such  adjudication  or 
award in arbitration.

(b)       In the event that a determination shall have been made pursuant to Section 10(a) of this Agreement that 
Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 12 shall 
be conducted in all respects as a de novo trial, or arbitration, on the merits and Indemnitee shall not be prejudiced by reason of 
that adverse determination.  In any judicial proceeding or arbitration commenced pursuant to this Section 12, the Company shall 
have the burden of proving Indemnitee is not entitled to indemnification or advancement, as the case may be.

(c)        If a determination shall have been made pursuant to Section 10(a) of this Agreement that Indemnitee is 
entitled  to  indemnification,  the  Company  shall  be  bound  by  such  determination  in  any  judicial  proceeding  or  arbitration 
commenced pursuant to this Section 12, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material 
fact necessary to make Indemnitee’s statement not materially 

ACTIVE/105005427.2

misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law.

(d)       The Company shall be precluded from asserting in any judicial proceeding or arbitration commenced 
pursuant to this Section 12 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and 
shall stipulate in any such court or before any such arbitrator that the Company is bound by all the provisions of this Agreement.  

(e)                The  Company  shall  indemnify  Indemnitee  to  the  fullest  extent  permitted  by  law  against  any  and  all 
Enforcement Expenses and, if requested by Indemnitee, shall (within thirty (30) days after receipt by the Company of a written 
request therefor) advance, to the extent not prohibited by law, such Enforcement Expenses to Indemnitee, which are incurred by 
Indemnitee in connection with any action brought by Indemnitee for indemnification or advancement from the Company under 
this Agreement or under any directors’ and officers’ liability insurance policies maintained by the Company in the suit for which 
indemnification  or  advancement  is  being  sought.    Such  written  request  for  advancement  shall  include  invoices  received  by 
Indemnitee  in  connection  with  such  Enforcement  Expenses  but,  in  the  case  of  invoices  in  connection  with  legal  services,  any 
references  to  legal  work  performed  or  to  expenditures  made  that  would  cause  Indemnitee  to  waive  any  privilege  accorded  by 
applicable law need not be included with the invoice.

(f)                Notwithstanding  anything  in  this  Agreement  to  the  contrary,  no  determination  as  to  entitlement  to 
indemnification under this Agreement shall be required to be made prior to the final disposition of the Proceeding, including any 
appeal therein.

Section 13.     Non-exclusivity; Survival of Rights; Insurance; Subrogation.

(a)        The rights of indemnification and to receive advancement as provided by this Agreement shall not be 
deemed  exclusive  of  any  other  rights  to  which  Indemnitee  may  at  any  time  be  entitled  under  applicable  law,  the  Charter,  the 
Bylaws, any agreement, a vote of stockholders or a resolution of directors, or otherwise.  No amendment, alteration or repeal of 
this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any 
action taken or omitted by such Indemnitee in his or her Corporate Status prior to such amendment, alteration or repeal.  To the 
extent  that  a  change  in  Delaware  law,  whether  by  statute  or  judicial  decision,  permits  greater  indemnification  or  advancement 
than  would  be  afforded  currently  under  the  Charter,  Bylaws  and  this  Agreement,  it  is  the  intent  of  the  parties  hereto  that 
Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change.  No right or remedy herein conferred 
is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to 
every  other  right  and  remedy  given  hereunder  or  now  or  hereafter  existing  at  law  or  in  equity  or  otherwise.    The  assertion  or 
employment  of  any  right  or  remedy  hereunder,  or  otherwise,  shall  not  prevent  the  concurrent  assertion  or  employment  of  any 
other right or remedy.

(b)       To the extent that the Company maintains an insurance policy or policies providing liability insurance 
for directors, managers, partners, officers, employees, agents or trustees of the Company or of any other Enterprise, Indemnitee 
shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available 
for any such director, manager, partner, officer, employee, agent or trustee under such policy or policies.  If, at the time of the 
receipt of a notice of a claim pursuant to the terms hereof, the Company has director and officer liability insurance in effect, the 
Company  shall  give  prompt  notice  of  such  claim  to  the  insurers  in  accordance  with  the  procedures  set  forth  in  the  respective 
policies.    The  Company  shall  thereafter  take  all  necessary  or  desirable  action  to  cause  such  insurers  to  pay,  on  behalf  of  the 
Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such policies. Upon request of 
Indemnitee, the Company shall also promptly provide to Indemnitee: (i) copies of all of the Company’s 

ACTIVE/105005427.2

11

 
 
 
 
 
 
potentially applicable directors’ and officers’ liability insurance policies, (ii) copies of such notices delivered to the applicable 
insurers,  and  (iii)  copies  of  all  subsequent  communications  and  correspondence  between  the  Company  and  such  insurers 
regarding the Proceeding. 

(c)        In the event of any payment under this Agreement, the Company shall be subrogated to the extent of 

such payment to all of the rights of recovery of Indemnitee, who shall execute all papers required and take all action necessary to 
secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such 
rights.

(d)       The Company’s obligation to provide indemnification or advancement hereunder to Indemnitee who is 
or  was  serving  at  the  request  of  the  Company  as  a  director,  manager,  partner,  officer,  employee,  agent  or  trustee  of  any  other 
Enterprise shall be reduced by any amount Indemnitee has actually received as indemnification or advancement from such other 
Enterprise.

Section 14.       Duration of Agreement.  This Agreement shall continue until and terminate upon the later of: (a) ten (10) 
years after the date that Indemnitee shall have ceased to serve as [both a director and] an officer of the Company or (b) one (1) 
year after the final termination of any Proceeding, including any appeal, then pending in respect of which Indemnitee is granted 
rights of indemnification or advancement hereunder and of any proceeding commenced by Indemnitee pursuant to Section 12 of 
this Agreement relating thereto.  This Agreement shall be binding upon the Company and its successors and assigns and shall 
inure to the benefit of Indemnitee and his or her heirs, executors and administrators.  The Company shall require and cause any 
successor (whether direct or indirect by purchase, merger, consolidation or otherwise) to all, substantially all or a substantial part, 
of the business and/or assets of the Company, by written agreement in form and substance satisfactory to Indemnitee, expressly to 
assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to 
perform if no such succession had taken place.

Section  15.            Severability.    If  any  provision  or  provisions  of  this  Agreement  shall  be  held  to  be  invalid,  illegal  or 
unenforceable  for  any  reason  whatsoever:  (a)  the  validity,  legality  and  enforceability  of  the  remaining  provisions  of  this 
Agreement (including, without limitation, each portion of any section of this Agreement containing any such provision held to be 
invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired 
thereby  and  shall  remain  enforceable  to  the  fullest  extent  permitted  by  law;  (b)  such  provision  or  provisions  shall  be  deemed 
reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; 
and (c) to the fullest extent possible, the provisions of this Agreement (including, without limitation, each portion of any section 
of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or 
unenforceable) shall be construed so as to give effect to the intent manifested thereby.

Section 16.      Enforcement.

(a)        The Company expressly confirms and agrees that it has entered into this Agreement and assumed the 
obligations imposed on it hereby in order to induce Indemnitee to serve or continue to serve as [a director and] an officer of the 
Company,  and  the  Company  acknowledges  that  Indemnitee  is  relying  upon  this  Agreement  in  serving  as  [a  director  and]  an 
officer of the Company.

(b)       This Agreement constitutes the entire agreement between the parties hereto with respect to the subject 
matter hereof and supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with 
respect to the subject matter hereof; provided, however, that this Agreement is a supplement to and in furtherance of the Charter, 
the Bylaws and applicable law, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee 
thereunder.

Section 17.      Modification and Waiver.  No supplement, modification or amendment, or waiver of any provision, of 
this  Agreement  shall  be  binding  unless  executed  in  writing  by  the  parties  thereto.    No  waiver  of  any  of  the  provisions  of  this 
Agreement shall be deemed or shall constitute a waiver of any other provisions of this Agreement nor shall any waiver constitute 
a  continuing  waiver.  No  supplement,  modification  or  amendment  of  this  Agreement  or  of  any  provision  hereof  shall  limit  or 
restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee prior to such 
supplement, modification or amendment.

Section 18.      Notice by Indemnitee.  Indemnitee agrees promptly to notify the Company in writing upon being served 
with  any  summons,  citation,  subpoena,  complaint,  indictment,  information  or  other  document  relating  to  any  Proceeding  or 
matter  which  may  be  subject  to  indemnification,  reimbursement  or  advancement  as  provided  hereunder.    The  failure  of

compensation, subject to Section 409A of the Code, where such claim is based on actions or failures to act by Indemnitee in his 
or her capacity as a service provider of the Company.  The parties intend that this Agreement be interpreted and construed with 
such intent.

Section 22.      Applicable Law and Consent to Jurisdiction.  This Agreement and the legal relations among the parties 
shall be governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without regard to its 
conflict  of  laws  rules.  Except  with  respect  to  any  arbitration  commenced  by  Indemnitee  pursuant  to  Section  12(a)  of  this 
Agreement, the Company and Indemnitee hereby irrevocably and unconditionally (i) agree that any action or proceeding arising 
out of or in connection with this Agreement shall be brought only in the Delaware Court, and not in any other state or federal 
court in the United States of America or any court in any other country, (ii) consent to submit to the exclusive jurisdiction of the 
Delaware  Court  for  purposes  of  any  action  or  proceeding  arising  out  of  or  in  connection  with  this  Agreement,  (iii)  consent  to

shall for all purposes be deemed to be an original but all of which together shall constitute one and the same Agreement.  Only 
one such counterpart signed by the party against whom enforceability is sought needs to be produced to evidence the existence of 
this Agreement.

Section  25.            Monetary  Damages  Insufficient/Specific  Enforcement.  The  Company  and  Indemnitee  agree  that  a 
monetary remedy for breach of this Agreement may be inadequate, impracticable and difficult of proof, and further agree that 
such  breach  may  cause  Indemnitee  irreparable  harm.  Accordingly,  the  parties  hereto  agree  that  Indemnitee  may  enforce  this 
Agreement by seeking injunctive relief and/or specific performance hereof, without any necessity of showing actual damage or 
irreparable harm (having agreed that actual and irreparable harm will result in not forcing the Company to specifically perform its 
obligations pursuant to this Agreement) and that by seeking injunctive relief and/or specific performance, Indemnitee shall not be 
precluded from seeking or obtaining any other relief to which he may be entitled. The Company and Indemnitee further agree 
that  Indemnitee  shall  be  entitled  to  such  specific  performance  and  injunctive  relief,  including  temporary  restraining  orders, 
preliminary  injunctions  and  permanent  injunctions,  without  the  necessity  of  posting  bonds  or  other  undertaking  in  connection 
therewith. The Company acknowledges that in the absence of a waiver, a bond or undertaking may be required of Indemnitee by 
the Court, and the Company hereby waives any such requirement of a bond or undertaking.

ADICET BIO, INC.
AMENDED AND RESTATED 
SENIOR EXECUTIVE CASH INCENTIVE BONUS PLAN

Exhibit 10.19

1.

Purpose

This Senior Executive Cash Incentive Bonus Plan (the “Incentive Plan”) is intended to provide an incentive for superior 

work and to motivate eligible executives of Adicet Bio, Inc. (the “Company”) and its subsidiaries toward even higher 
achievement and business results, to tie their goals and interests to those of the Company and its stockholders and to enable the 
Company to attract and retain highly qualified executives.  The Incentive Plan is for the benefit of Covered Executives (as 
defined below).

2.

Covered Executives

From time to time, the Compensation Committee of the Board of Directors of the Company (the “Compensation 

Committee”) may select certain key executives (the “Covered Executives”) to be eligible to receive bonuses hereunder.  
Participation in this Plan does not change the “at will” nature of a Covered Executive’s employment with the Company.

3.

4.

Administration

The Compensation Committee shall have the sole discretion and authority to administer and interpret the Incentive Plan.

Bonus Determinations

a.

Corporate Performance Goals.  A Covered Executive may receive a bonus payment under the Incentive Plan 

based upon the attainment of one or more performance objectives that are established by the Compensation Committee in its sole 
discretion and relate to financial and/or operational metrics with respect to the Company or any of its subsidiaries (the 
“Corporate Performance Goals”), including the following:  cash flow (including, but not limited to, operating cash flow and free 
cash flow); research and development, publication, clinical and/or regulatory milestones; revenue; corporate revenue; earnings 
before interest, taxes, depreciation and amortization; net income (loss) (either before or after interest, taxes, depreciation and/or 
amortization); changes in the market price of the Company’s common stock; economic value-added; acquisitions or strategic 
transactions, including licenses, collaborations, joint ventures or promotion arrangements; operating income (loss); return on 
capital, assets, equity, or investment; total stockholder returns; coverage decisions; return on sales; gross or net profit levels; 
productivity; expense efficiency; margins; operating efficiency; working capital; earnings (loss) per share of the Company’s 
common stock; sales or market shares; number of prescriptions or prescribing physicians; revenue; corporate revenue; operating 
income and/or net annual recurring revenue; or any other performance goal selected by the Compensation Committee, any of 
which may be (A) measured in absolute terms or compared to any incremental increase, (B) measured in terms of growth, (C) 
compared to another company or companies or to results of a peer group, (D) measured against the market as a whole and/or as 
compared to applicable market indices and/or (E) measured on a pre-tax or post-tax basis (if applicable).  Further, any Corporate 
Performance Goals may be used to measure the performance of the Company as a whole or a business unit or other segment of 
the Company, or one or more product lines or specific markets.  The Corporate Performance Goals may differ from Covered 
Executive to Covered Executive and from performance period to performance period. 

b.

Calculation of Corporate Performance Goals.  At the beginning of each applicable performance period, the 

Compensation Committee will determine whether any significant element(s) will be included in or 

 
excluded from the calculation of any Corporate Performance Goal with respect to any Covered Executive.  In all other respects, 
Corporate Performance Goals will be calculated in accordance with the Company’s financial statements, generally accepted 
accounting principles, or under a methodology established by the Compensation Committee at the beginning of the performance 
period and which is consistently applied with respect to a Corporate Performance Goal in the relevant performance period.  

c.

Target; Minimum; Maximum.  Each Corporate Performance Goal shall have a “target” (100 percent attainment 

of the Corporate Performance Goal) and may also have a “minimum” hurdle and/or a “maximum” amount.  

d.

Bonus Requirements; Individual Goals.  Except as otherwise set forth in this Section 4(d):  (i) any bonuses paid 

to Covered Executives under the Incentive Plan shall be based upon objectively determinable bonus formulas that tie such 
bonuses to one or more performance targets relating to the Corporate Performance Goals, (ii) bonus formulas for Covered 
Executives shall be adopted in each performance period by the Compensation Committee and communicated to each Covered 
Executive at the beginning of each performance period and (iii) no bonuses shall be paid to Covered Executives unless and until 
the Compensation Committee makes a determination with respect to the attainment of the performance targets relating to the 
Corporate Performance Goals.  Notwithstanding the foregoing, the Compensation Committee may adjust bonuses payable under 
the Incentive Plan based on achievement of one or more individual performance objectives or pay bonuses (including, without 
limitation, discretionary bonuses) to Covered Executives under the Incentive Plan based on individual performance goals and/or 
upon such other terms and conditions as the Compensation Committee may in its discretion determine.

e.

Individual Target Bonuses.  The Compensation Committee shall establish a target bonus opportunity for each 

Covered Executive for each performance period.  For each Covered Executive, the Compensation Committee shall have the 
authority to apportion the target award so that a portion of the target award shall be tied to attainment of Corporate Performance 
Goals and a portion of the target award shall be tied to attainment of individual performance objectives. 

f.

Employment Requirement.  Subject to any additional terms contained in a written agreement between the 

Covered Executive and the Company, the payment of a bonus to a Covered Executive with respect to a performance period shall 
be conditioned upon the Covered Executive’s employment by the Company on the bonus payment date.  If a Covered Executive 
was not employed for an entire performance period, the Compensation Committee may pro rate the bonus based on the number 
of days employed during such period.

5.

Timing of Payment

a.

With respect to Corporate Performance Goals established and measured on a basis more frequently than 

annually (e.g., quarterly or semi-annually), the Corporate Performance Goals will be measured at the end of each performance 
period after the Company’s financial reports with respect to such period(s) have been published.  If the Corporate Performance 
Goals and/or individual goals for such period are met, payments will be made as soon as practicable following the end of such 
period, but not later than 74 days after the end of the fiscal year in which such performance period ends.

b.

With respect to Corporate Performance Goals established and measured on an annual or multi-year basis, 

Corporate Performance Goals will be measured as of the end of each such performance period (e.g., the end of each fiscal year) 
after the Company’s financial reports with respect to such period(s) have been published.  If the Corporate Performance Goals 
and/or individual goals for any such period are met, bonus payments will be made as soon as practicable, but not later than 74 
days, after the end of the relevant fiscal year.  

c.

For the avoidance of doubt, bonuses earned at any time in a fiscal year must be paid no later than 74 days after 

the last day of such fiscal year.

6.

Amendment and Termination

The Company reserves the right to amend or terminate the Incentive Plan at any time in its sole discretion.

7.  Company Recoupment Rights

A Covered Executive’s rights with respect to any award granted pursuant to the Incentive Plan shall in all events be 

subject to reduction, cancellation, forfeiture or recoupment to the extent necessary to comply with (i) any right that the Company 
may have under any Company clawback, forfeiture or recoupment policy as in effect from time to time or other agreement or 
arrangement with a Covered Executive, or (ii) applicable law. 

Adopted by the Board on December 21, 2017, as amended on January 27, 2022.
