Overview

We are a clinical-stage biopharmaceutical company focused on providing novel cell therapies to people with cancer. We are a

leader in the development of T-cell therapies for solid tumors.

Our proprietary SPEAR (Specific Peptide Enhanced Affinity Receptor) T-cell platform enables us to identify cancer targets, find

and genetically engineer T-cell receptors (“TCRs”) against those targets, and produce therapeutic candidates (“SPEAR T-cells”) for
administration to patients. Using our affinity engineered TCRs, we aim to become the first company to have a TCR T-cell approved for the
treatment of a solid tumor indication. We have clinical trials ongoing with our wholly-owned ADP-A2M4, ADP-A2M4CD8 (the
“SURPASS” trial), each targeting the MAGE-A4 antigen, and ADP-A2AFP SPEAR T-cells targeting the AFP cancer antigen in a total of
ten solid tumor types including non-small cell lung cancer (“NSCLC”), head and neck cancer, ovarian, urothelial, melanoma,
hepatocellular, esophageal, gastric, synovial sarcoma and myxoid round cell liposarcoma (“MRCLS”) cancers. Current data provide an
encouraging demonstration of the potential of our SPEAR T-cell platform across multiple targets and a range of solid tumors:

ADP-A2M4—Multiple Indications: A Phase 1 clinical trial is ongoing in urothelial, melanoma, head and neck, ovarian, NSCLC,

esophageal and gastric cancers, synovial sarcoma and MRCLS. RECIST responses have been reported in patients with synovial sarcoma
and head and neck cancer. A radiation sub-study under this Phase 1 clinical trial is continuing with a partial response being seen in the first
patient treated. A Phase 2 clinical trial has been initiated in synovial sarcoma and MRCLS indications. In addition, planning is ongoing for
initiation of a clinical trial combining ADP-A2M4 with a PD-1 / PD-L1 pathway inhibitor in 2020.

ADP-A2AFP - Hepatocellular Carcinoma: We continue dosing patients in our Phase 1, open-label, dose-escalation study

designed to evaluate the safety and anti-tumor activity of our alpha fetoprotein (“AFP”) therapeutic candidate for the treatment of
hepatocellular carcinoma, or HCC. Patients are being treated with target doses of 5 billion SPEAR T-cells (range 1.2 to 6 billion) and the
first patient treated at this target dose achieved a partial response.

ADP-A2M4CD8—SURPASS Trial: Enrollment has started in a Phase 1 trial for a next generation SPEAR T-cell, ADP-

A2M4CD8. This next generation SPEAR T-cell utilizes the same engineered T-cell receptor as ADP-A2M4, but with the addition of a
CD8α homodimer. The addition of the CD8α homodimer has been shown in vitro to increase cytokine release and SPEAR T-cell potency.
A partial response was reported in the first patient treated.

A fourth SPEAR T-cell, the NY-ESO SPEAR T-cell, was transitioned to GlaxoSmithKline (“GSK”) in 2018, following GSK’s

exercise of its option to obtain an exclusive global license to the NY-ESO SPEAR T-cell program in September 2017.

We have our own manufacturing facility in the United States that manufactures SPEAR T-cells to treat patients across a broad

range of solid tumors. We also have our own dedicated vector manufacturing in the United Kingdom which, together with our US
manufacturing facility, will enable us to continue improving the effectiveness and patient experience associated with our cell therapies.

We continue to develop our preclinical pipeline of new cell therapies, including SPEAR T-cells, CAR-Ts and novel HLA

independent TCR (“HiT”) therapies to both new targets and to existing targets towards further HLA types. As part of this research and
development, we are developing next generation and combination approaches to enhance our cell therapies. These are being developed
internally and in collaboration with third parties including Alpine Immune Sciences (“Alpine”) and Noile-Immune Biotech Inc. (“Noile-
Immune”).

We have also developed an allogeneic platform for “off-the-shelf” cell immunotherapies, including CAR-T and TCR T-cells. On

January 13, 2020, we entered into an agreement with Universal Cells Inc. (“Universal Cells”), a wholly-owned subsidiary of Astellas
Pharma Inc., for the co-development and co-commercialization of stem-cell derived allogeneic CAR-T and TCR T-cell therapies. The
agreement covers the co-development and co-commercialization of up

1

Table of Contents

to three T-cell therapies and combines Universal Cells’ donor cell gene editing platform and our stem-cell derived allogeneic T-cell
platform. Universal Cells also has the right to select two targets and develop allogeneic cell therapy candidates independently. This
agreement follows collaboration with Universal Cells Inc. since 2015 on the development of gene-edited induced pluripotent stem cells
(iPSCs), for which Adaptimmune has the exclusive rights to develop and commercialize resulting T-cell therapy products using its
proprietary process for generating T-cells from iPSCs.

Business Strategy

Building on our leadership position with T-cell therapies in solid tumor indications, our strategic objective is to be a world leader
in designing and delivering cell therapies that transform the lives of people with cancer. We have an ambition to have the first TCR T-cell
therapy approved for a solid tumor indication. In order to achieve our objectives, we are focused on the following:

Progressing our T-cell therapies through research and development. We continue to advance our T-cell therapies through

development including our SPEAR T-cells which are in clinical trials in multiple tumor indications.  In research, we are developing new
cell therapies which we aim to advance into clinical trials, to treat different indications and patient populations, on completion of pre-clinical
testing. For example, we are generating SPEAR T-cells, CAR-T and HLA independent TCR T-cells (“HiT”) against multiple tumor
indications.

Advancing our cell therapies towards commercialization. Depending on data from Phase 1 clinical trials, we will rapidly progress
clinical candidates through clinical trials and towards commercialization. For example, our ADP-A2M4 therapy is in a Phase 2 clinical trial,
called SPEARHEAD-1, in North America, Canada, UK and the European Union for the treatment of patients with synovial sarcoma and
MRCLS. Depending on the data obtained, we aim to progress quickly towards commercialization of ADP-A2M4 in these indications.
Planning for commercialization of this therapy is in progress.

Continuing to develop ‘off-the-shelf’ cell immunotherapies. We are progressing with our allogeneic (or ‘off the shelf’) platform

for the development of cell therapies, both internally and in collaboration with partners. We believe, using an “off-the-shelf” product will be
transformative for patients. The platform is being developed to facilitate manufacture of multiple cell therapy products including TCR T-
cells, CAR-T cells and other cell therapies.

Continuing to develop next-generation and combination approaches to further enhance our cell therapies. We continue to

evaluate and work to understand the tumor micro-environment and the mechanism of action of our cell therapies in order to enhance them.
We will continue to progress these approaches internally and through multiple external collaborations including those with Alpine and
Noile-Immune. These approaches include next generation approaches like ADP-A2M4CD8, currently in the SURPASS Phase 1 trial, for
which the aim is to increase cytokine release and SPEAR T-cell potency, as well as combination approaches like our intended combination
trial with a PD-1/ PD-L1 pathway inhibitor.

Continuing to improve our manufacturing and patient supply processes to optimize how we deliver our cell therapies to

patients. We are continuing to enhance our T-cell and vector manufacturing processes at all stages of the process. Improvements may
enhance the end cell therapy product and reduce overall turnaround time, all of which will enable us to treat patients quicker and more
effectively.

Building an integrated cell therapy company capable of delivering our cell therapies to patients. We continue to build and

develop our capabilities as an integrated cell therapy company across all activities required for researching, developing, manufacturing,
supplying and commercializing our cell therapies. Having a fully integrated capability across all these areas enables flexibility and control.

Expanding our intellectual property portfolio. We intend to continue building on our technology platform, comprising
intellectual property, proprietary methods and know-how in the field of cell therapies. These assets form the foundation for our ability to
strengthen our product pipeline and to defend and expand our position as a leader in the field of cell therapies.

Our Cell Therapies

The Immune System and T-cells

The immune system plays an important role in targeting and destroying cancer cells. Specifically, T-cells, which are a type of
white blood cell, and their receptors create a natural system that is designed to scan the body for diseased cells. In general, cells process
proteins internally and then convert these proteins into peptide fragments which are then presented on the cell surface by a protein complex
called the Human Leukocyte Antigen, or HLA. T-cells naturally scan all other cells in the body for the presence of abnormal peptide
fragments, such as those generated from infectious agents. Recognition of this peptide-HLA complex takes place through the TCR
expressed on the T-cells. However, binding of naturally occurring TCRs to cancer targets tends to be very poor because cancer proteins
appear very similar to naturally occurring proteins on healthy cells.

Target Identification and Validation

Before developing any engineered T-cell therapy, it is important to identify and validate a suitable target cancer peptide or protein.
The target must be expressed primarily only on the cancer cells of interest and with expression in normal non-cancerous tissue only where a
risk to the patient would be deemed acceptable. Careful validation and identification of targets is important to ensuring that any engineered
cell therapy is specific to the targeted cancer and does not bind to the same target on non-cancer cells, or that the receptor in the cell therapy
does not recognize a similar peptide or protein derived in normal cells. Our target identification platform is focused on three approaches.
First, we are using our platform to validate cancer testis antigens, for example the MAGE-A4 antigen. Second, we are using our platform to
identify non-cancer testis antigens which are closely related to a specific disease indication, for example the AFP antigen. Finally, we are
identifying intracellular targets in the context of different HLA types or extracellular cell surface targets for HLA-independent constructs
ensuring that we can address a broader patient population either across multiple HLA types or without HLA restriction, respectively.

Engineering of T-cells

Following identification of a suitable target peptide, we identify TCRs or other cell therapy receptors (for example CAR) that are
capable of binding to that target peptide or protein. We then engineer and optimize those identified receptors to enhance and optimize their
ability to recognize and bind to the cancer targets, thereby enabling a highly targeted immunotherapy which complements a patient’s
immune system. The optimized cell therapy then undergoes extensive preclinical safety testing prior to administration to patients. Our
SPEAR T-cell platform technology which utilizes affinity engineered TCRs enables us to develop a pipeline of targets and TCR therapeutic
candidates that we believe may be effective in a variety of cancer types that are unresponsive to currently available and experimental
therapies. We have three wholly owned SPEAR T-cells currently in clinical trials (ADP-A2M4CD8, ADP-A2M4 and ADP-A2AFP) and a
pipeline of SPEAR T-cells and other cell therapies in development, including SPEAR T-cells directed to peptides expressed in the context
of different HLA-types.

Other cell therapies being developed include CAR T-cells where a CAR (Chimeric Antigen Receptor) is engineered to recognize

proteins expressed on the surface of the cancer cells to enable the T-cells to be directed to and to recognize those cancer cells and HLA-
independent TCRs (HiTs) which are able to recognize cell surface antigens expressed by cancer cells independently of HLA.

Administration to Patients

The current process for treating a patient with our cell therapies involves extracting the patient’s T-cells and then combining the

extracted cells with our delivery system containing the gene for our engineered cell therapy, through a process known as transduction. Our
delivery system uses a type of self-inactivating (SIN) virus, known as SIN-lentivirus, to transduce the patient’s T-cells (“lentiviral vector”).
The transduced T-cells are then expanded and infused back into the patient. When these T-cells encounter a recognized peptide or protein,
they multiply and initiate the destruction of the targeted cancer cells.

Our Wholly Owned Clinical Product Pipeline

* Site specific protocol amendment with MD Anderson Cancer Center
** Bladder, Melanoma, Head & Neck, Ovarian, NSCLC, Esophageal, Gastric, Synovial sarcoma, MRCLS (myxoid/round cell liposarcoma)

ADP-A2M4—Multiple Indications: Clinical trials are ongoing with our ADP-A2M4 SPEAR T-cell in multiple indications. In

addition, planning is ongoing for initiation of a clinical trial combining ADP-A2M4 with a PD-1 / PD-L1 pathway inhibitor in 2020.

● A Phase 1 clinical trial in multiple tumor indications, namely urothelial, melanoma, head and neck, ovarian, NSCLC,

esophageal and gastric cancers, synovial sarcoma and MRCLS completed enrollment in early 2020.

o As of October 23, 2019, data from 14 evaluable patients with synovial sarcoma treated in the expansion phase of
this trial demonstrated an overall response rate of 50% (including both confirmed and unconfirmed partial
responses (PRs)). 13 out of 14 evaluable patients had evidence of disease control (with best overall responses of
partial response (7 patients) or stable disease (6 patients)). A clinical update was provided at the Connective
Tissue Oncology Society in November 2019.

o Beyond synovial sarcoma tumor shrinkage has been observed in patients with melanoma and ovarian cancers and

a partial response was reported in a head and neck cancer patient.

● A Phase 2 clinical trial has been initiated in synovial sarcoma and MRCLS (“Spearhead -1”). The trial will take place at

sites in the United States, Canada and Europe. The trial will include up to 60 patients at a selected dose of up to 10 billion
transduced ADP-A2M4 SPEAR T-cells. Primary responses will be assessed by overall response rate by RECIST v1.1
(“Response Evaluation Criteria In Solid Tumors v1.1”). The lymphodepletion regimen will be fludarabine (30 mg/m2/day)
for 4 days and cyclophosphamide (600 mg/m2/day) for 3 days.

● A radiation sub-study under the Phase 1 clinical trial is continuing at the MD Anderson Cancer Center. The sub-study will
treat up to 10 patients and has a primary endpoint of safety, with RECIST v1.1 responses being a secondary endpoint. The
radiation is a low dose radiation and is administered to lesions or isocenters prior to lymphodepletion.

ADP-A2AFP - Hepatocellular Carcinoma: We continue dosing patients in our Phase 1, open-label, dose-escalation study

designed to evaluate the safety and anti-tumor activity of our alpha fetoprotein (“AFP”) therapeutic candidate for the treatment of
hepatocellular carcinoma, or HCC. The trial is open in the United States, United Kingdom

4

Table of Contents

and the European Union. Patients are now enrolling in Cohort 3 and are being treated with target doses of 5 billion SPEAR T-cells (range
1.2 to 6 billion). The first patient treated in this cohort had a confirmed PR (decrease of 100% in target lesions). Most adverse events to date
are consistent with those typically experienced by cancer patients undergoing cytotoxic chemotherapy or other cancer immunotherapies.

ADP-A2M4CD8—SURPASS Trial: Enrollment has started in a Phase 1 trial for a next generation SPEAR T-cell, ADP-

A2M4CD8. This next generation SPEAR T-cell utilizes the same engineered T-cell receptor as ADP-A2M4, but with the addition of a
CD8α homodimer. The addition of the CD8α homodimer has been shown in vitro to increase cytokine release and SPEAR T-cell potency.
The SURPASS trial will enroll up to 30 patients across multiple solid tumor indications. Similar to our other trials, the SURPASS trial will
include dose escalation. Unlike the other trials, the stagger between patients will be shorter and the starting dose in the first cohort will be
0.8 to 1.2 billion SPEAR T-cells, instead of 100 million SPEAR T-cells, as was previously the case. Each dose cohort will enroll three
patients and can be expanded to six patients if a dose limiting toxicity occurs. After dose escalation is complete, there is an Expansion Phase
with doses up to 10 billion cells. The lymphodepletion regimen will be fludarabine (30 mg/m2/day) for 4 days and cyclophosphamide (600
mg/m2/day) for 3 days. A partial response was reported in the first patient treated.

ADP-A2M10: Two Phase 1 clinical trials were conducted with ADP-A2M10 for the treatment of (i) NSCLC, and (ii) urothelial,

melanoma and head and neck cancers in the United States, Canada, the United Kingdom and Spain. Enrollment in these trials closed as
planned in 2019.

NY-ESO SPEAR T-cell Therapy (transitioned to GSK)

A fourth SPEAR T-cell, the NY-ESO SPEAR T-cell, was transitioned to GlaxoSmithKline (“GSK”) in 2018, following GSK’s
exercise of its option to obtain an exclusive global license to the NY-ESO SPEAR T-cell program in September 2017. GSK has assumed
full responsibility for all development, manufacturing and commercialization activities for the NY-ESO SPEAR T-cell, including
progression of this SPEAR T-cell into further clinical trials. Under the ongoing Collaboration and License Agreement with GSK, a third
target program remains ongoing. GSK is currently entitled to nominate a fourth target program and, upon satisfying other conditions, may
have the right to nominate a fifth program under the GSK Collaboration and License Agreement, in each case excluding our ongoing
wholly-owned development programs.

Preclinical candidates and next generation technology

We continue to progress development of new SPEAR T-cells and other cell therapies including HLA-independent TCRs (HiTs)
and CAR-Ts directed to new targets and to targets expressed in the context of HLA-types other than HLA-A2. As part of our preclinical
development we also have multiple development programs ongoing both internally and with third party collaborators to develop various
approaches to enhance our cell therapy products.

Allogeneic iPSC platform

We are looking to develop our SPEAR, CAR and HiT candidates in T-cells that are universally applicable to all patients by developing
gene-edited inducible pluripotent stem cells (iPSC) differentiated to T-cells by our in-house proprietary process. These “off-the shelf cells”
are being developed to overcome the current limitation of autologous therapies that need to be manufactured specifically for each patient
and donor-derived T-cells which may need repeated infusions. The enhanced T-cell technology being developed involves selective
engineering for the removal of certain cell surface proteins (for example, Human Leukocyte Antigen (“HLA”) molecules) and the addition
of our receptor candidates,

5

Table of Contents

without the use of nucleases, to develop these T-cell products. If successful, this will enable us to treat our patients with an off-the-shelf cell
therapy product

Manufacturing Platform Development

Manufacturing Capability

We have our own SPEAR T-cell manufacturing capability at the Navy Yard in Philadelphia, Pennsylvania which is capable of

manufacturing all of our wholly owned assets across a range of solid tumors. The Navy Yard facility is currently able to produce SPEAR T-
cell product for up to 10 patients per month. With further investment the facility could treat over 1,000 patients per year. We also have the
ability to use third party contract manufacturing if required to increase capacity.

We have our own dedicated vector manufacturing capability in the United Kingdom, within the Catapult Cell and Gene Therapy
Manufacturing Centre in Stevenage, which is now able to produce vector for our Phase 1 clinical trials. The first batch of GMP vector was
completed in Q4 of 2019 and is pending final quality release testing. Control of our own end-to-end manufacturing process (including
vector, T-cell and analytical quality control testing) enables us to improve and further develop our processes for manufacture of our cell
therapies. We continue to work with our third-party vector manufacturer for supply of vectors to support our ongoing clinical trials.

Manufacturing Improvements

We have the goal of reducing the time between apheresis of a patient and return of affinity enhanced SPEAR T-cells back to the
patient. We have made a number of changes to our current SPEAR T-cell manufacturing process and are continuing to make changes. We
are now able to manufacture SPEAR T-cells with a 25-day processing time and we continue to optimize further. The combination of
integrated manufacturing capability with continuing process development enables us to continue to be a leader in cell therapy manufacture.

Core Alliances and Collaborations

Universal Cells Co-development Collaboration Agreement

On January 13, 2020, Adaptimmune Therapeutics plc (the “Company” or “Adaptimmune”) entered into a Co-development and

Co-commercialization agreement (“Agreement”) with Universal Cells, Inc., a wholly-owned subsidiary of Astellas Pharma Inc (“Universal
Cells”).

Under the Agreement the parties will agree on up to three targets and will co-develop T-cell therapies directed to those targets pursuant to
an agreed research plan. For each target, Universal Cells will fund co-development up until completion of a Phase 1 trial for products
directed to such target. Upon completion of the Phase 1 trial for a product, Universal Cells and Adaptimmune will elect whether to progress
with co-development and co-commercialization of such product, or to allow the other party to pursue the candidate independently.

If the parties progress with co-development and co-commercialization of a product, then each party will grant the other party a co-exclusive
license to co-develop and co-commercialize such product in the field of T-cell therapy. If a product is developed solely by one party, then
the other party will grant to the continuing party an exclusive license to develop and commercialize such product in the field of T-cell
therapy.

In addition, Universal Cells is also granted the right to develop, independently of Adaptimmune, allogeneic T-cell therapy candidates
directed to two targets selected by Universal Cells. Universal Cells will have sole rights to develop and commercialize products directed
against such products.

Under the terms of the agreement, Adaptimmune may receive up to $897.5 million in payments, including:

●

An upfront payment of $50 million.

●
●

Development milestones of up to $73.75 million for each co-developed and co-commercialized product
Development milestones of up to $147.5 million per product and up to $110 million in sales milestones for products developed
unilaterally by Universal Cells.

In addition, Adaptimmune will receive research funding of up to $7.5 million per year and tiered royalties on net sales in the mid-

single to mid-teen digits.

Under the terms of the Agreement and in consideration for rights under certain contributed Universal Cells technology for a product

unilaterally developed by Adaptimmune, Universal Cells may receive up to $552.5 million, including up to $147.5 million in milestone
payments per product and up to $110 million in sales milestones for products developed unilaterally by Adaptimmune. In addition,
Universal Cells will receive tiered royalties on net sales in the mid-single to mid-teen digits.

To the extent that Universal Cells and Adaptimmune co-develop and co-commercialize any product, the parties will share equally all

worldwide costs and profits. Further details governing the parties’ co-commercialization will be articulated in a product-specific
commercialization agreement.

Either party can terminate the Agreement in the event of material breach or insolvency of the other party. Universal Cells can

terminate the Agreement for convenience in its entirety or partly in relation to any targets and products directed to such targets.
Adaptimmune can terminate the Agreement for convenience in relation to any target it is unilaterally developing and to products directed to
such target.

In addition to the Agreement, the parties have also made amendments to the pre-existing agreement between Universal Cells, Inc. and

Adaptimmune which was announced on December 1, 2015. The pre-existing agreement relates to the use of Universal Cells gene editing
and HLA-editing technology in the context of the development of our own allogeneic T-cell therapies. The amendments relate primarily to
changes to the development plan agreed between the parties and the pre-existing agreement has been amended and re-stated as at January
13, 2020 as a result of the changes agreed. Adaptimmune retains exclusive rights in the T-cell field under the agreement.

GSK Collaboration and License Agreement

We entered into the GSK Collaboration and License Agreement regarding the development, manufacture and commercialization
of TCR therapeutic candidates in May 2014. The collaboration is for up to five programs. The first program was the NY-ESO SPEAR T-
cell program, in relation to which GSK has now exercised its option to take an exclusive license. The second program related to
development of a SPEAR T-cell to a peptide derived from the PRAME antigen. This program has now completed. The third target program
with GSK remains ongoing.

Under the terms of the GSK Collaboration and License Agreement, the Company may be entitled to:

●

●

●

development milestones of up to £18 million ($23 million) per product and HLA-type for the NY-ESO Program and up to
£21.5 million ($27.3 million) per product and HLA-type for other programs (including the third target program);
regulatory milestones of up to £36 million ($45.7 million) per product and HLA-type for the NY-ESO program and up to £40
million ($50.8 million) per product and HLA-type for other programs (including the third target program); and
commercialization milestones upon the first commercial sale of a product of up to £70.5 million ($89.5 million) per product
and HLA-type for the NY-ESO Program and up to £80 million ($101.5 million) per product and HLA-type for other programs
(including the third target program).

The development and regulatory milestones are per product milestones and are dependent on achievement of certain obligations, the 

nature of the product being developed, stage of development of product, territory in which an obligation is achieved and type of indication 
or indications in relation to which the product is being developed. In addition, for any program, multiple products may be developed in the 
context of different HLA-types.  As of December 31, 2019, we had achieved development milestones of $69.6 million.

7

Table of Contents

For other programs (including the third target program) under the GSK Collaboration and License Agreement, an option fee is also
payable of up to £6 million ($7.6 million) on exercise of the option by GSK, after which GSK is responsible for all development expenses.

For any product that is commercialized by GSK, the Company may receive tiered sales milestones up to £200 million ($253.8

million) per product and HLA-type and mid-single to low double-digit royalties on worldwide net sales of the applicable product. Royalties
are payable while there is a jointly owned or solely owned valid patent claim covering the SPEAR T-cell in the country in which the
relevant SPEAR T-cell is being sold and, in each case, for a minimum of 10 years from first commercial sale of the relevant TCR
therapeutic. Sales milestones also apply once any TCR therapeutic covered by the GSK Collaboration and License Agreement is on the
market.

On September 7, 2017, we announced that GSK had exercised its exclusive option for the NY-ESO SPEAR T-cell program.

Transition of the program to GSK occurred during 2018. GSK has now assumed full responsibility for the NY-ESO SPEAR T-cell program
including any ongoing clinical trials. As a result of the option exercise, Adaptimmune received £48 million (approximately $61 million)
from GSK over the course of the transition period. This included development milestones of £18 million (approximately $23 million) and
an option payment of £30 million (approximately $38 million), which also allows GSK to nominate two additional targets following
completion of the transition. Successful continuation of development and subsequent commercialization of NY-ESO would trigger
additional payments for development milestones, tiered sales milestones, and mid-single to low double-digit royalties on worldwide net
sales.

Upon nomination of the third target program by GSK, we have granted to GSK an exclusive option to the nominated target which

can be exercised up to four months after approval of an IND application in relation to a TCR therapeutic candidate directed against the
nominated target. We are responsible for taking the third target program through preclinical testing and up to IND application filing. GSK is
responsible for the IND filing itself should the preclinical testing and development be favorable.

Two other targets may be nominated by GSK at specified times under the GSK Collaboration and License Agreement, excluding
any wholly-owned research programs already in progress by us. Upon nomination by GSK of any of these two additional targets, we will
grant to GSK an exclusive option on each target, which can be exercised up to four months after approval of an IND application in relation
to a TCR therapeutic candidate directed against the nominated target. Nomination also triggers the start of a collaboration program to
develop the relevant TCR therapeutic candidate directed to the nominated target peptide.

Following exercise of any option (including the options for the NY-ESO SPEAR T-cell and third target programs), we will grant

to (and have granted in relation to the NY-ESO SPEAR T-cell) GSK an exclusive worldwide license under intellectual property rights
specific to the SPEAR T-cell developed under the relevant collaboration programs. GSK will, at its own expense, be fully responsible for
all further development and commercialization of the relevant T-cell candidates. The licenses do not include a right for GSK to develop
alternative affinity-enhanced TCRs using our intellectual property rights or to develop other TCR therapeutic candidates directed to
different target peptides. Under the agreement, we are also prohibited from independently developing or commercializing T-cell
therapeutics directed at the targets subject to outstanding options granted to GSK.

The GSK Collaboration and License Agreement is effective until all payment obligations expire, including any ongoing royalty

payments due in relation to GSK’s sale of any covered TCR therapeutic candidates. The agreement can also be terminated on a
collaboration program-by-collaboration program basis by GSK for lack of feasibility or inability to meet certain agreed requirements. Both
parties have rights to terminate the agreement for material breach upon 60 days’ written notice or immediately upon insolvency of the other
party. GSK has additional rights to terminate either the agreement or any specific license or collaboration program upon 60 days’ written
notice to us. Additional payments may be due to us as a result of such termination, and where we continue any development of any TCR
therapeutic candidate resulting from a terminated collaboration program, depending on the stage of development, royalties may be payable
to GSK at a mid-single-digit percentage rate of net sales. We also have rights to terminate any license where GSK ceases development or
withdraws any licensed SPEAR T-cells in specified circumstances.

Preclinical and Clinical Collaborations

We have third party collaborations in place with Noile-Immune, Alpine Immune Sciences and Bellicum.

With Alpine, we are collaborating to develop next-generation SPEAR T-cell products that incorporate Alpine’s secreted and

transmembrane immunomodulatory protein technology. The collaboration agreement was announced in May 2019, and we believe that the
Alpine technology will complement our existing internal next generation technology and enhance anti-tumor potential through engagement
of further rapid and flexible immunomodulatory mechanisms. In the Noile-Immune collaboration, announced in August 2019, we will co-
develop next-generation SPEAR T-cell products, incorporating Noile-Immune’s PRIME (proliferation inducing and migration enhancing)
technology, based upon co-expression of IL-7 and CCL19. Under the Bellicum collaboration we are evaluating Bellicum’s GoTCR
technology (inducible MyD88/CD40 co-stimulation, or iMC) with our SPEAR T-cells for the potential to create enhanced T-cell
therapeutics.

We also have a strategic alliance agreement with the MD Anderson Cancer Center which covers both the conduct of certain

clinical trials for our SPEAR T-cell therapies and also certain pre-clinical research work.

Intellectual Property

We actively seek to protect the intellectual property and proprietary technology that we believe is important to our business,

including seeking, maintaining, enforcing and defending patent rights for our SPEAR T-cells and processes, whether developed internally
or licensed from third parties. Our success will depend on our ability to obtain and maintain patent and other protection including
data/market exclusivity for our cell therapies, manufacturing and platform technology, preserve the confidentiality of our know-how and
trade secrets and operate without infringing the valid and enforceable patents and proprietary rights of third parties. See “Risk Factors—
Risks Related to Our Intellectual Property.”

Our policy is to seek to protect our proprietary position generally by filing an initial priority filing at the U.K. Intellectual Property

Office (“UKIPO”) and/or the U.S. Patent Trademark Office (“USPTO”). This is followed by the filing of a patent application under the
Patent Co-operation Treaty claiming priority from the initial application(s) and then application for patent grant in, for example, the United
States, Europe (including major European territories), Japan, Australia, New Zealand, India and Canada. In each case, we determine the
strategy and territories required after discussion with our patent professionals to ensure that we obtain relevant coverage in territories that
are commercially important to us and reflect the scope of cell therapies being developed. We will additionally rely on data exclusivity,
market exclusivity and patent term extensions when available, including as relevant exclusivity through orphan or pediatric drug
designation. We also rely on trade secrets and know-how relating to our underlying platform technologies, manufacturing processes and
pre-clinical candidates.

As of December 31, 2019 we owned or jointly owned approximately 143 granted patents (of which 20 are U.S.-issued patents) and

172 pending patent applications (of which 37 are U.S. National patent applications).

Product Patent families

ADP-A2AFP - We own a patent application covering the composition of matter of ADP-A2AFP. The patent application claims
are primarily directed to the engineered TCR therapeutic candidate, the use of the ADP-A2AFP therapy and in particular the amino acid
substitutions required for such engineered TCR therapeutic candidate. An initial priority patent application was filed in the UKIPO and a
patent application under the applicable Patent Co-operation Treaty has since been filed claiming priority from that United Kingdom patent
application. National applications have been filed in all commercially relevant territories and claims have been allowed in Europe and the
US. We expect any composition of matter patents within this family, if issued, and if the appropriate maintenance, renewal, annuity, or other
governmental fees are paid, to expire in 2034 (worldwide, excluding possible patent term extensions).

therapeutic candidate and in particular the amino acid substitutions required for such engineered TCR therapeutic candidate. Patent
applications have also been filed in relation to the use of ADP-A2M4 in combination with PD-L1/PD-1 inhibitors. The initial priority patent
applications were filed in the UKIPO and patent applications under the applicable Patent Co-operation Treaty have since been filed
claiming priority from that United Kingdom patent application. National applications have been filed in all commercially relevant
territories. We expect any composition of matter patents within this family, if issued, and if the appropriate maintenance, renewal, annuity,
or other governmental fees are paid, to expire in 2037-2039 (worldwide, excluding possible patent term extensions).

ADP-A2M4CD8 – We own a patent application covering the composition of matter of ADP-A2M4CD8 and other related TCR T-

cell therapies. The patent application claims are directed to the engineered TCR therapeutic candidate in combination with the CD8 next
generation technology. The initial priority patent applications were filed in the UKIPO and patent applications under the applicable Patent
Co-operation Treaty have since been filed claiming priority from that United Kingdom patent application. We expect any composition of
matter patents within this family, if issued, and if the appropriate maintenance, renewal, annuity, or other governmental fees are paid, to
expire in 2037-2039 (worldwide, excluding possible patent term extensions).

ADP-A2M10 - We own patent applications covering the composition of matter of ADP-A2M10. The patent application claims are

directed to the engineered TCR therapeutic candidate and in particular the amino acid substitutions required for such engineered TCR
therapeutic candidate. An initial priority patent application was filed in the United Kingdom Intellectual Property Office (“UKIPO”) and a
patent application under the applicable Patent Co-operation Treaty has since been filed claiming priority from that United Kingdom patent
application. National applications have been filed in all commercially relevant territories. We expect any composition of matter patents
within this family, if issued, and if the appropriate maintenance, renewal, annuity, or other governmental fees are paid, to expire in 2035
(worldwide, excluding possible patent term extensions).

We also have product patent applications filed in relation to our new cell therapy candidates including candidates to new targets

and our new HLA-independent T-cell therapies (HiTs).

Platform Technology

We own a number of platform technology patents and patent applications which are directed to certain aspects of the process that we use to
engineer our SPEAR TCRs and other cell therapies. These are owned jointly with Immunocore Limited, with whom we have historically
had a shared development history.

Novel targets - We have filed 29 patent applications under the Patent Cooperation Treaty which cover peptides expressed on the

tumor cell surface and the TCRs which recognize them. The applications as filed cover 872 peptides from 63 different target proteins.
National applications have been filed in all commercially relevant territories.

TCR libraries - We have filed 10 patent applications which cover large libraries of TCR genes which we have generated and the
method of their generation: these act as proprietary sources for screening for TCRs, which are the starting points for affinity engineering
into clinical candidates. National applications have been filed in all commercially relevant territories

Di-sulphide bond - patents directed to the di-sulphide bond stabilization technique required to solubilize TCRs for isolation,

characterization and validation have been issued in major territories including Australia, Canada, China, major European territories
(including the United Kingdom, France, Germany, Spain and Italy), India, Hong Kong, Japan, the United States and South Africa and are
expected to expire beginning in 2022.

Phage Display technology - Patents have also been granted in relation to our phage display approach for receptor development
and are expected to expire beginning in 2023 if the appropriate maintenance, renewal, annuity, or other governmental fees are paid. The
priority patent application was filed in 2002 and patents are now granted in the United States, Australia, Canada, China, major European
territories (including the United Kingdom, France, Germany, Spain and Italy), Japan, South Africa, India, Norway and New Zealand.

10

Table of Contents

We also have an issued patent directed to a method for increasing the affinity of given TCRs to a target peptide. (expected to

expire in 2025) and patent applications directed to decreasing off-target reactivity and selection for the affinity-enhanced TCRs.

Manufacturing Process Patents and Patent Applications

We have trade secrets and patent applications relating to the manufacture of our cell therapies. For example, we have filed patent

applications in commercially relevant territories, which claim priority from initial priority patent applications filed at the USPTO and
UKIPO, which are directed to a particular modification to the lentiviral vector technology. We believe this modification enhances the safety
profile of the lentiviral vector technology. This has been granted in the United States and allowed in Europe. Further patent applications
have been filed on the manufacturing and quality control of our products.

Preclinical and Next Generation Approaches

We have 4 patent applications filed covering a range of next generation technology approaches and/or combination approaches.

Allogeneic iPSC platform approaches

We have filed a number of patent applications covering our proprietary iPSC stem cell differentiation technology which enables

the differentiation of stem cells into T-cells which can then be administered to patients. The patent applications are primarily directed to the
various stages required for the differentiation of the iPSC stem cells into different cell line types including NK cells, NKT cells,
macrophages, dendritic cells, alphabeta T-cells, and gammadelta T-cells.

Third-Party Intellectual Property Rights

We have a non-exclusive license from ThermoFisher Inc. under certain of its intellectual property rights covering its Dynabeads®
CD3/CD28 technology. This technology is used in our manufacturing process to isolate, activate and expand patient T-cells. We also have a
supply agreement which runs until December 31, 2025 under which we are required to purchase CD3/CD28 magnetic bead product. See
“Risk Factors—Risks Related to Our Reliance Upon Third Parties—We rely heavily on ThermoFisher and the technology we license from
them.”

Third-party patents do exist that purport to cover some of our current lentiviral vectors/systems or our process for manufacture.

However, the majority of these patents will expire prior to any commercial supply by us of any cell therapies and we do not currently
require a license. Whether licenses are required under any remaining third-party patents or other third-party patents depends on what steps
we take going forward in relation to our lentiviral transduction process and manufacturing process including our allogeneic manufacturing
and differentiation process. We may, however, need to negotiate a license under any remaining third party patents or develop alternative
strategies for dealing with any remaining third party patents if licenses are not available on commercially acceptable terms or at all.

Competition

The biotechnology and pharmaceutical industries are characterized by rapidly advancing technologies, intense competition, a

strong emphasis on proprietary products and intellectual property. While we believe that our scientific knowledge, technology and
development experience provide us with competitive advantages, we face potential competition from many different sources, including
major pharmaceutical, specialty pharmaceutical and biotechnology companies, academic institutions, governmental agencies and public and
private research institutions. Any SPEAR T-cells that we successfully develop and commercialize will compete with existing products and
new products that may become available in the future.

Immunotherapy is an active area of research and a number of immune-related products have been identified in recent years that

are alleged to modulate the immune system. Many of these products utilize dendritic cells, a form of immune cell that presents cancer
target peptides to T cells and that can in turn result in T-cell activation. More recently, bi-specific antibodies and checkpoint inhibitors (for
instance PD-1/PD-L1 antibodies) have been identified as having utility in the treatment of cancer. Bi-specific antibodies commonly target
both the cancer target, or in some cases peptide-HLA complex (so-called “TCR mimics”), and link to the CD3 molecule of T cells, thus
bringing both cancer cells and T cells into close proximity to maximize the chance of T-cell binding and hence an immune response to the
cancer cells. Checkpoint inhibitors, on the other hand work by targeting receptors that inhibit T-cell effectiveness and proliferation and
essentially activate T cells. Other immunotherapies that are being actively investigated include: antibody-drug complexes, TCR-mimic
antibodies, oncolytic viruses, cancer vaccines. A variety of cell-based autologous and allogeneic (“off-the-shelf”) approaches are also being
researched and developed, including but not limited to: CAR-T cell, TCR T-cell, GammaDelta T-cell, CAR-NK cell, NK cell, NKT cell
and CTL.

● CAR-T in hematological malignancies: Engineered T-cell therapeutics have been identified using antibody recognition systems
engineered into T cells, so-called CAR-T cells. A number of targets in hematological malignancies have been well characterized
including, but not limited to: BCMA, CD4, CD5, CD19, CD22, CD20, CD33, CD38, CD70, CS1 and CD123. Two CD-19 directed
CAR-T cell products have been approved by the U.S. Food and Drug Administration (“FDA”) Kymriah™ (tisagenlecleucel) and
Yescarta™ (axicabtagene ciloleucel) as well as by the European Medicines Agency (EMA) in the European Union. More recently,
Kymriah™ has been approved by the MHLW in Japan. A number of companies and academic institutions are developing CAR-T
cell products including but not limited to Allogene Therapeutics, Arcellx, Atara Bio, Autolus, Baylor College of Medicine, bluebird
bio, CASI Pharmaceuticals, Celyad, Celgene (now part of Bristol-Myers Squibb), Cellectis, CRISPR Therapeutics, Fate
Therapeutics, Janssen (JNJ with Nanjing Legend), Juno Therapeutics (a Bristol-Myers Squibb company), Kite Pharma (Gilead),
Linea Rx, Mustang Bio, Novartis, Precigen, Refuge Biotechnologies Inc., Servier, Sorrento Therapeutics, Xenetic Biosciences,
Xyphos (a wholly-owned subsidiary of Astellas) and Ziopharm Oncology.

● CAR-T in solid tumors: In addition to hematological malignancies, there are a growing number of pharmaceutical, biotechnology,
and academic institutions researching and developing autologous and allogeneic CAR-T therapies in the solid tumor setting. These
CAR-T cell therapies are at a variety of stages of preclinical and clinical development, as well as directed towards a broad target
spectrum, including but not limited to: DLL3, EGFR, GD2, HER-2, IL13rα2, Lewis Y, L1-CAM, Mesothelin, MUC16, PSCA,
PSMA and ROR1. Competitors include but are not limited to: Allogene Therapeutics, Amgen, Atara Bio, Aurora Biopharma,
Baylor College of Medicine, Cell Medica, Bellicum, BioNTech, Carisma Therapeutics (formerly CARMA Therapeutics), Carsgen,
Celgene (now part of Bristol-Myers Squibb; with Obsidian Therapeutics) Cellectis Therapeutics, Celyad, CRISPR Therapeutics,

Therapeutics, Precigen, Senti Biosciences, Sorrento Therapeutics, Symvivo, Targazyme, Tmunity, Xyphos (a wholly-owned
subsidiary of Astellas).

● CARs & TCR-mimics targeting peptide-HLA complexes: Most CAR-T therapies in development are directed towards suitable
antigen targets. Another area of development is the creation of CAR-T that selectively binds to the peptide-HLA (pHLA) complex
(the natural binding site for endogenous TCR). Furthermore, competitors are also looking at pHLA antibodies or TCR mimic
antibodies that can either be engineered in T-cells or developed as standalone antibody therapies in cancer indications (both
hematologic malignancies and solid tumors). Targets of such pHLA CAR-T or TCR mimic antibodies include: AFP, CD19, BCMA,
NY-ESO-1, p53 and WT1. A number of pharmaceutical, biotechnology, and academic institutions are researching and developing
CARs & TCRmimics targeting the peptide-HLA complex, including but not limited to: Adicet Bio / Regeneron, Altor Bioscience,
Cancer Research Technology/CRUK, Eureka Therapeutics, Gritstone Oncology, MorphoSys, Xencor and Ziopharm Oncology.
● TCR T-cells: TCR T-cells are being developed by competitors that are directed towards a multitude of targets including: AFP,
CD20, HPV-16 E6/E7, KRAS, MAGE-A1, MAGE-A3, MAGE A3/A6, MART1, NRAS, NY-ESO-1, p53, PRAME, TGFβRII
frameshift antigen WT1, as well as personalized neoantigens. Juno Therapeutics (a Bristol-Myers Squibb company) has developed
an engineered TCR therapeutic candidate where

12

Table of Contents

the end TCR is purported to have enhanced affinity through stem-cell selection. Juno’s candidate JTCR016 (WT1-specific TCR), in
collaboration with Fred Hutchinson Cancer Research Center and the National Cancer Institute (NCI), is currently undergoing a
Phase 1/2 trial in NSCLC and mesothelioma setting as well as a separate Phase 1/2 in AML. Medigene AG has reported
development of a PRAME TCR therapeutic candidate (MDG1011), which has begun a Phase 1/2 clinical investigation in AML,
MM and myelodysplastic syndromes. In addition to Juno there is a growing number of TCR companies that are adopting
approaches to TCR affinity enhancement, for example Axis Therapeutics, Takara, Takara Bio, Fred Hutchinson Cancer Centre and
Immatics. In addition other TCR-focused competitors include, but are not limited to: 3T, Adaptive Biotechnologies (with
Genentech), AgenTus, Atreca, Baylor College, Bellicum, BioNTech (with Eli Lilly), bluebird bio, BlueSphere bio, Captain T cell,

Zelluna (with Oslo University Hospital) and Ziopharm Oncology.

There are a number of different approaches being developed for allogeneic or “off-the-shelf” immunotherapy products including

stem-cell derived products, HLA-matched products, healthy-donor derived products and use of cells with no or limited HLA type (for
example GammaDelta T-cell, or NK cells). Competitors include Allogene Therapeutics (with Notch Therapeutics), Century Therapeutics
(with FujiFilm Cellular Dynamics), City of Hope (with Mustang Bio), Editas (through Juno/Celgene/Bristol Myers Squibb), Fate
Therapeutics, Takeda (in collaboration with CiRA), Thyas, Editas, UCLA and T-CiRA.

In addition to adoptive cell therapy approaches aforementioned, our competitors are also investigating other cell-based
approaches, including the potential of GammaDelta T-cell, CAR-Macrophages, CAR-NK cell, NK cell, NKT cell, CTLs, TILs, Marrow-
infiltrating lymphocytes (MILs), Multi-tumor-associated antigen (TAA)-specific T-cells and virus-specific T-cells either preclinically or in
a clinical setting (both hematologic malignancies and solid tumors). In this space there are a number of potential competitors, including, but
not limited to: Achilles Therapeutics, Adicet Bio, Arsenal bio, Atara Bio, Aurora BioPharma, Cell Medica, Cellular Biomedicine Group

Government Regulation and Product Approvals

Government authorities in the United States, at the federal, state and local level, and in other countries and jurisdictions, including

the European Union, extensively regulate, among other things, the research, development, testing, manufacture, quality control, approval,
packaging, storage, recordkeeping, labeling, advertising, promotion, distribution, marketing, post-approval monitoring and reporting, and
import and export of pharmaceutical products. The processes for obtaining regulatory approvals in the United States and in foreign
countries and jurisdictions, along with subsequent compliance with applicable statutes and regulations and other regulatory authorities,
require the expenditure of substantial time and financial resources.

The failure to comply with applicable U.S. requirements at any time during the product development process, approval process or
after approval may subject an applicant and/or sponsor to a variety of administrative or judicial sanctions, including refusal by the FDA to
approve pending applications, withdrawal of an approval, imposition of a clinical hold, issuance of warning letters and other types of
letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government
contracts, restitution, disgorgement

13

Table of Contents

of profits, or civil or criminal investigations and penalties brought by the FDA and the Department of Justice (“DOJ”), or other
governmental entities.

FDA Approval Process

In the United States, therapeutic products, including drugs, biologics, and medical devices are subject to extensive regulation by
the FDA. The Federal Food, Drug, and Cosmetic Act (the “FDC Act”), and other federal and state statutes and regulations, govern, among
other things, the research, development, testing, manufacture, storage, recordkeeping, approval, labeling, promotion and marketing,
distribution, post-approval monitoring and reporting, sampling, and import and export of pharmaceutical products. Some biological
products are subject to regulation under the FDC Act. Most biological products are approved for marketing under provisions of the Public
Health Service Act (“PHSA”) via a Biologics License Application (“BLA”). The application process and requirements for approval of
BLAs are generally similar to those for new drug applications (“NDAs”), and biologics are associated with generally similar, if not greater,
approval risks and costs as drugs. Failure to comply with applicable U.S. requirements may subject a company to a variety of administrative
or judicial sanctions, such as FDA refusal to approve pending NDAs or BLAs, warning or untitled letters, product recalls, product seizures,
total or partial suspension of production or distribution, injunctions, fines, civil penalties, and criminal prosecution.

Biological product development for a new product or certain changes to an approved product in the United States typically
involves preclinical laboratory and animal tests, the submission to the FDA of an IND, which must become effective before human clinical
testing may commence, and adequate and well-controlled clinical trials to establish the safety and effectiveness of the drug for each
indication for which FDA approval is sought. Satisfaction of FDA pre-market approval requirements typically takes many years and the
actual time required may vary substantially based upon the type, complexity, and novelty of the product or disease.

Preclinical tests include laboratory evaluation of product chemistry, formulation, and toxicity, as well as animal trials to assess the
characteristics and potential safety and efficacy of the product. The conduct of the preclinical tests must comply with federal regulations and
requirements, including good laboratory practices. The results of preclinical testing are submitted to the FDA as part of an IND along with
other information, including information about product chemistry, manufacturing and controls, and a proposed clinical trial protocol. Long-
term preclinical tests, such as animal tests of reproductive toxicity and carcinogenicity, may continue after the IND is submitted.

A 30-day waiting period after the submission of each IND is required prior to the commencement of clinical testing in humans. If

the FDA has not communicated deficiencies with the IND within this 30-day period, the clinical trial proposed in the IND may begin.

Clinical trials involve the administration of the investigational biologic to healthy volunteers or patients under the supervision of a

qualified investigator. Clinical trials must be conducted: (i) in compliance with federal regulations; (ii) in compliance with good clinical
practice, or GCP, an international standard meant to protect the rights and health of patients and to define the roles of clinical trial sponsors,
administrators, and monitors; as well as (iii) under protocols detailing the objectives of the trial, the parameters to be used in monitoring
safety, and the effectiveness criteria to be evaluated. Each protocol involving testing on U.S. patients and subsequent protocol amendments
must be submitted to the FDA as part of the IND.

The FDA may order the temporary, or permanent, discontinuation of a clinical trial at any time, or impose other sanctions, if it
believes that the clinical trial either is not being conducted in accordance with FDA requirements or presents an unacceptable risk to the
clinical trial patients. The trial protocol and informed consent information for patients in clinical trials must also be submitted to an IRB for
approval. An IRB may also require the clinical trial at the site to be halted, either temporarily or permanently, for failure to comply with the
IRB’s requirements, or may impose other conditions.

Clinical trials to support BLAs for marketing approval are typically conducted in three sequential phases, but the phases may

overlap. In Phase 1, the initial introduction of the biologic into healthy human subjects or patients, the product is tested to assess
metabolism, pharmacokinetics, pharmacological actions, side effects associated with

14

Table of Contents

increasing doses, and, if possible, early evidence on effectiveness. Phase 2 usually involves trials in a limited patient population to determine
the effectiveness of the drug or biologic for a particular indication, dosage tolerance, and optimum dosage, and to identify common adverse
effects and safety risks. If a compound demonstrates evidence of effectiveness and an acceptable safety profile in Phase 2 evaluations,
Phase 3 trials are undertaken to obtain the additional information about clinical efficacy and safety in a larger number of patients, typically
at geographically dispersed clinical trial sites, to permit the FDA to evaluate the overall benefit-risk relationship of the drug or biologic and
to provide adequate information for the labeling of the product.

In most cases, the FDA requires two adequate and well-controlled clinical trials to demonstrate the efficacy of the biologic. A

single Phase 3 trial with other confirmatory evidence may be sufficient in some instances where the trial is a large multicenter trial
demonstrating internal consistency and a statistically very persuasive finding of a clinically meaningful effect on mortality, irreversible
morbidity or prevention of a disease with a potentially serious outcome and confirmation of the result in a second trial would be practically
or ethically impossible.

After completion of the required clinical testing, a BLA is prepared and submitted to the FDA. FDA approval of the BLA is

required before marketing of the product may begin in the United States. The BLA must include the results of all preclinical, clinical, and
other testing, compilation of data relating to the product’s pharmacology, chemistry, manufacture, and controls as well as proposed labeling
for the product. The cost of preparing and submitting a BLA is substantial. The submission of most BLAs is additionally subject to a
substantial application user fee, currently exceeding $2,335,000, and the manufacturer and/or sponsor under an approved new drug
application are also subject to annual product and establishment user fees, currently exceeding $110,000 per product and $569,000 per
establishment. These fees are typically increased annually.

The FDA has 60 days from its receipt of a BLA to determine whether the application will be accepted for filing based on the

agency’s threshold determination that it is sufficiently complete to permit substantive review. Once the submission is accepted for filing,
the FDA begins an in-depth review. The FDA has agreed to certain performance goals in the review of BLAs. Most such applications for
standard review biologic products are reviewed within 10 months of the date the FDA files the BLA; most applications for priority review
biologics are reviewed within six months of the date the FDA files the BLA. Priority review can be applied to a biologic that the FDA
determines has the potential to treat a serious or life-threatening condition and, if approved, would be a significant improvement in safety or
effectiveness compared to available therapies. The review process for both standard and priority review may be extended by the FDA for
three additional months to consider certain late-submitted information, or information intended to clarify information already provided in
the submission.

The FDA may also refer applications for novel biologic products, or biologic products that present difficult questions of safety or

efficacy, to an advisory committee—typically a panel that includes clinicians and other experts—for review, evaluation, and a
recommendation as to whether the application should be approved. The FDA is not bound by the recommendation of an advisory
committee, but it generally follows such recommendations. Before approving a BLA, the FDA will typically inspect one or more clinical
sites to assure compliance with GCP. Additionally, the FDA will inspect the facility or the facilities at which the biologic product is
manufactured. The FDA will not approve the product unless compliance with current good manufacturing practice cGMP is satisfactory and
the BLA contains data that provide substantial evidence that the biologic is safe, pure, potent and effective in the indication studied.

After the FDA evaluates the BLA, it issues either an approval letter or a complete response letter. A complete response letter

generally outlines the deficiencies in the submission and may require substantial additional testing, or information, in order for the FDA to
reconsider the application. If, or when, those deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the BLA, the
FDA will issue an approval letter. The FDA has committed to reviewing such resubmissions in two or six months depending on the type of
information included.

An approval letter authorizes commercial marketing of the biologic with specific prescribing information for specific indications.
As a condition of BLA approval, the FDA may require a risk evaluation and mitigation strategy (“REMS”) to help ensure that the benefits
of the biologic outweigh the potential risks. REMS can include medication guides, communication plans for healthcare professionals, and
elements to assure safe use (“ETASU”). ETASU can include, but are not limited to, special training or certification for prescribing or
dispensing, dispensing only under

15

Table of Contents

certain circumstances, special monitoring, and the use of patient registries. The requirement for a REMS can materially affect the potential
market and profitability of the product. Moreover, product approval may require substantial post-approval testing and surveillance to
monitor the product’s safety or efficacy. Once granted, product approvals may be withdrawn if compliance with regulatory standards is not
maintained or problems are identified following initial marketing.

Changes to some of the conditions established in an approved application, including changes in indications, labeling, or
manufacturing processes or facilities, may require submission and FDA approval of a BLA supplement before the change can be
implemented. A BLA supplement for a new indication may require clinical data similar to that in the original application, and the FDA uses
the same procedures and actions in reviewing BLA supplements as it does in reviewing BLAs.

FDA Guidance Governing Gene Therapy Products

The FDA has issued various guidance documents regarding gene therapies, which outline additional factors that the FDA will

consider at each of the above stages of development and relate to, among other things, the proper preclinical assessment of gene therapies;
the chemistry, manufacturing, and controls information that should be included in an IND application; the proper design of tests to measure
product potency in support of an IND application or BLA; and measures to observe delayed adverse effects in subjects who have been
exposed to investigational gene therapies when the risk of such effects is high.

Expedited Pathways

The FDA is required to facilitate the development, and expedite the review, of biologics that are intended for the treatment of a
serious or life- threatening disease or condition for which there is no effective treatment and which demonstrate the potential to address
unmet medical needs for the condition. These expedited programs include fast track designation, breakthrough therapy designation,
accelerated approval, and priority review designation.

Fast Track Designation

Under the fast track program, the sponsor of a new biologic candidate may request that the FDA designate the candidate for a

specific indication as a fast track biologic concurrent with, or after, the filing of the IND for the candidate. The FDA must determine if the
biologic candidate qualifies for fast track designation within 60 days of receipt of the sponsor’s request.

Benefits such as the ability to engage in more frequent interactions with the FDA, the FDA may initiate review of sections of a fast

track product’s BLA before the application is complete. This rolling review is available if the applicant provides, and the FDA approves, a
schedule for the submission of the remaining information and the applicant pays applicable user fees. However, the FDA’s time period goal
for reviewing an application does not begin until the last section of the BLA is submitted. Additionally, the fast track designation may be
withdrawn by the FDA if the FDA believes that the designation is no longer supported by data emerging in the clinical trial process.

Accelerated Approval

Under the fast track program and FDA’s accelerated approval regulations, the FDA may approve a biologic for a serious or life-
threatening illness that provides meaningful therapeutic benefit to patients over existing treatments based upon 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.

In clinical trials, a surrogate endpoint is a measurement of laboratory or clinical signs of a disease or condition that substitutes for
a direct measurement of how a patient feels, functions, or survives. Surrogate endpoints can often be measured more easily or more rapidly
than clinical endpoints. A biologic candidate approved on this basis is subject to

16

Table of Contents

rigorous post- marketing compliance requirements, including the completion of Phase 4 or post-approval clinical trials to confirm the effect
on the clinical endpoint. Failure to conduct required post-approval trials, or confirm a clinical benefit during post-marketing trials, will allow
the FDA to withdraw the biologic from the market on an expedited basis. All promotional materials for biologic candidates approved under
accelerated regulations are subject to prior review by the FDA.

Breakthrough Therapy Designation

The FDA is also required to expedite the development and review of the application for approval of biological products that are

intended to treat a serious or life-threatening disease or condition where preliminary clinical evidence indicates that the biologic may
demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints.

Under the breakthrough therapy program, the sponsor of a new biologic candidate may request that the FDA designate the
candidate for a specific indication as a breakthrough therapy concurrent with, or after, the filing of the IND for the biologic candidate. The
FDA must determine if the biological product qualifies for breakthrough therapy designation within 60 days of receipt of the sponsor’s 
request.  Breakthrough Therapy Designation has all of the benefits of Fast Track designation as well as additional benefits such as FDA 
organizational commitment and intensive FDA guidance. 

The FDA may also award RMAT designation (Regenerative Medicine Advanced Therapy designation) to regenerative medicine

products. An RMAT designation is similar to breakthrough therapy designation and includes increased opportunities to meet with FDA
officials and early meetings to discuss potential surrogate or intermediate endpoints. RMAT designation is available to regenerative
medicine therapies where the therapy is intended to treat, modify, reverse or cure a serious or life-threatening disease or condition and the
preliminary clinical evidence indicates that the therapy has the potential to address unmet medical needs for the disease or condition.

Orphan Drug Designation

Under the Orphan Drug Act, the FDA may grant orphan drug designation to biological products intended to treat a rare disease or

condition, generally a disease or condition that affects fewer than 200,000 individuals in the United States, or if it affects more than
200,000 individuals in the United States, there is no reasonable expectation that the cost of developing and making a product available in
the United States for such disease or condition will be recovered from sales of the product. Orphan drug designation must be requested
before submitting a BLA. After the FDA grants orphan drug designation, the identity of the biological product 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. The first BLA applicant to receive FDA approval for a particular active moiety to treat a particular disease
with FDA orphan drug designation is entitled to a seven-year exclusive marketing period in the United States for that product for that
indication. During the seven-year exclusivity period, the FDA may not approve any other applications to market a biological product
containing the same active moiety for the same disease, except in limited circumstances, such as a showing of clinical superiority to the
product with orphan drug exclusivity. A product is clinically superior if it is safer, more effective or makes a major contribution to patient
care. Orphan drug exclusivity does not prevent the FDA from approving a different drug or biological product for the same disease or
condition, or the same biological product 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 user fee.

Disclosure of Clinical Trial Information

Sponsors of human clinical trials of FDA-regulated products, including biological products, are required to register and disclose
certain clinical trial information. Information related to the product, patient population, phase of investigation, trial sites and investigators,
and other aspects of the clinical trial is then made public as part of the registration. Sponsors are also obligated to discuss the results of their
clinical trials after completion. Disclosure of the results of these trials can be delayed until the new product or new indication being studied
has been approved.

17

Table of Contents

Competitors may use this publicly available information to gain knowledge regarding the progress of development programs.

Pediatric Information

Under the Pediatric Research Equity Act, or PREA, NDAs or BLAs or efficacy supplements to NDAs or BLAs must contain data

to assess the safety and effectiveness of the biological product for the claimed indications in all relevant pediatric subpopulations and to
support dosing and administration for each pediatric subpopulation for which the biological product is safe and effective. The FDA may
grant full or partial waivers, or deferrals, for submission of data. Unless otherwise required by regulation, PREA does not apply to any
biological product for an indication for which orphan designation has been granted. Under the Best Pharmaceuticals for Children Act, or 
BPCA, a sponsor that qualifies for “pediatric exclusivity” is entitled to an additional six months of market exclusivity if it complies with a 
Written Request, or WR, issued by FDA for pediatric studies.  The sponsor may apply to FDA to issue a WR.  Pediatric exclusivity may 
apply to patent rights and to FDA regulatory exclusivity and operates by adding six months of exclusivity on to the end of the latest-
expiring form of exclusivity.  To qualify for pediatric exclusivity, at least one of those rights must still be currently in force at the time 
FDA approves the pediatric studies.

Additional Controls for Biologics

To help reduce the increased risk of the introduction of adventitious agents, the PHSA emphasizes the importance of

manufacturing controls for products whose attributes cannot be precisely defined. The PHSA also provides authority to the FDA to
immediately suspend licenses in situations where there exists a danger to public health, to prepare or procure products in the event of
shortages and critical public health needs, and to authorize the creation and enforcement of regulations to prevent the introduction or spread
of communicable diseases in the United States and between states.

After a BLA is approved, the product may also be subject to official lot release as a condition of approval. As part of the
manufacturing process, the manufacturer is required to perform certain tests on each lot of the product before it is released for distribution.
If the product is subject to official release by the FDA, the manufacturer submits samples of each lot of product to the FDA together with a
release protocol showing a summary of the history of manufacture of the lot and the results of all of the manufacturer’s tests performed on
the lot. The FDA may also perform certain confirmatory tests on lots of some products, such as viral vaccines, before releasing the lots for
distribution by the manufacturer. In addition, the FDA conducts laboratory research related to the regulatory standards on the safety, purity,
potency, and effectiveness of biological products. As with drugs, after approval of biologics, manufacturers must address any safety issues
that arise, are subject to recalls or a halt in manufacturing, and are subject to periodic inspection after approval.

Biosimilars

The Biologics Price Competition and Innovation Act of 2009, or BPCIA, created an abbreviated approval pathway for biological

products shown to be highly similar to or interchangeable with an FDA-licensed reference biological product. Under the BPCIA, a
biological product may be deemed biosimilar to an FDA-approved biological product or reference biological product upon a showing that
there are no differences in conditions of use, route of administration, dosage form, and strength, and no clinically meaningful differences
between the biological product and the reference product in terms of safety, purity, and potency. Biosimilarity generally must be shown
through analytical trials, animal trials, and a clinical trial or trials, unless the Secretary waives a required element. A biosimilar product may
be deemed interchangeable with a prior approved product if it meets the higher hurdle of demonstrating that it can be expected to produce
the same clinical results as the reference product and, for products administered multiple times, the biologic and the reference biologic may
be switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive
use of the reference biologic. On March 6, 2015, the FDA approved the first biosimilar product under the BPCIA. As of January 2019, the
FDA had approved a total of 17 biosimilars, and seven of these had been launched into the U.S. market.

18

Table of Contents

Complexities associated with the larger, and often more complex, structures of biological products, as well as the process by which 

such products are manufactured, pose significant hurdles to implementation, which is still being evaluated by the FDA. Controversy over 
the appropriate manner of naming biosimilars has caused delay as well, with FDA currently calling for biosimilar names to have a random 
four-letter suffix appended to the name of the reference compound to which they refer.  In addition, complexities of the regulatory 
provisions of the BPCIA, as well as the patent litigation provisions in the statute and accompanying litigation, have also led to a relatively 
slow pace of biosimilar approvals.  FDA is taking steps to address these issues, most recently issuing the Biosimilars Action Plan, or BAP, 
to increase the speed and efficiency of biosimilar approvals and usage in the clinical setting.

A reference biologic is granted 12 years of marketing exclusivity from the time of first licensure of the reference product, and in

addition no application for a biosimilar can be submitted for four years from the date of licensure of the reference product. The first
biologic product submitted under the abbreviated approval pathway that is determined to be interchangeable with the reference product has
exclusivity against a finding of interchangeability for other biologics for the same condition of use for the lesser of (i) one year after first
commercial marketing of the first interchangeable biosimilar, (ii) eighteen months after the first interchangeable biosimilar is approved if
there is no patent challenge, (iii) eighteen months after resolution of a lawsuit over the patents of the reference biologic in favor of the first
interchangeable biosimilar applicant, or (iv) 42 months after the first interchangeable biosimilar’s application has been approved if a patent
lawsuit is ongoing within the 42-month period.

Post-Approval Requirements

Once a BLA is approved, a product will be subject to certain post-approval requirements. For instance, the FDA closely regulates

the post-approval marketing and promotion of biologics, including standards and regulations for direct-to-consumer advertising, off-label
promotion, industry- sponsored scientific and educational activities and promotional activities involving the internet. Biologics may be
marketed only for the approved indications and in accordance with the provisions of the approved labeling.

Adverse event reporting and submission of periodic reports is required following FDA approval of a BLA. The FDA also may
require post-marketing testing, known as Phase 4 testing, REMS, and surveillance to monitor the effects of an approved product, or the
FDA may place conditions on an approval that could restrict the distribution or use of the product. In addition, quality control, biological
product manufacture, packaging, and labeling procedures must continue to conform to cGMPs after approval. Biologic manufacturers and
certain of their subcontractors are required to register their establishments with the FDA and certain state agencies. Registration with the
FDA subjects entities to periodic unannounced inspections by the FDA, during which the agency inspects manufacturing facilities to assess
compliance with cGMPs. Accordingly, manufacturers must continue to expend time, money, and effort in the areas of production and
quality-control to maintain compliance with cGMPs. Regulatory authorities may withdraw product approvals or request product recalls if a
company fails to comply with regulatory standards, if it encounters problems following initial marketing, or if previously unrecognized
problems are subsequently discovered.

FDA Regulation of Companion Diagnostics

If safe and effective use of a therapeutic product depends on an in vitro diagnostic, then the FDA generally will require approval

or clearance of the diagnostic, known as a companion diagnostic, at the same time that the FDA approves the therapeutic product. The FDA
has generally required in vitro companion diagnostics intended to select the patients who will respond to cancer treatment to obtain
marketing approval through the pre-market approval (“PMA”) process for that diagnostic simultaneously with approval of the therapeutic.
The review of these in vitro companion diagnostics in conjunction with the review of a cancer therapeutic involves coordination of review
by the FDA’s Center for Biologics Evaluation and Research and by the FDA’s Center for Devices and Radiological Health.

The PMA process, including the gathering of clinical and preclinical data and the submission to and review by the FDA, can take

several years or longer. It involves a rigorous premarket review during which the applicant must prepare and provide the FDA with
reasonable assurance of the device’s safety and effectiveness and information about the device and its components regarding, among other
things, device design, manufacturing and labeling. PMA applications are subject to an application fee, which exceeds $250,000 for most
PMAs. In addition, PMAs for certain

19

Table of Contents

devices must generally include the results from extensive preclinical and adequate and well-controlled clinical trials to establish the safety
and effectiveness of the device for each indication for which FDA approval is sought. In particular, for a diagnostic, the applicant must
demonstrate that the diagnostic produces reproducible results when the same sample is tested multiple times by multiple users at multiple
laboratories. As part of the PMA review, the FDA will typically inspect the manufacturer’s facilities for compliance with the Quality
System Regulation, or QSR, which imposes elaborate testing, control, documentation and other quality assurance requirements.

PMA approval is not guaranteed, and the FDA may ultimately respond to a PMA submission with a not approvable determination

based on deficiencies in the application and require additional clinical trial or other data that may be expensive and time-consuming to
generate and that can substantially delay approval. If the FDA finds the PMA application is approvable, the FDA typically issues an
approvable letter requiring the applicant’s agreement to specific conditions, such as changes in labeling, or specific additional information,
such as submission of final labeling, in order to secure final approval of the PMA. If the FDA concludes that the applicable criteria have
been met, the FDA will issue a PMA for the approved indications, which can be more limited than those originally sought by the applicant.
The PMA can include post-approval conditions that the FDA believes necessary to ensure the safety and effectiveness of the device,
including, among other things, restrictions on labeling, promotion, sale and distribution.

After a device is placed on the market, it remains subject to significant regulatory requirements. Medical devices may be marketed

only for the uses and indications for which they are cleared or approved. Device manufacturers must also establish registration and device
listings with the FDA. A medical device manufacturer’s manufacturing processes and those of its suppliers are required to comply with the
applicable portions of the QSR, which cover the methods and documentation of the design, testing, production, processes, controls, quality
assurance, labeling, packaging and shipping of medical devices. Domestic facility records and manufacturing processes are subject to
periodic unscheduled inspections by the FDA. The FDA also may inspect foreign facilities that export products to the United States.

Anti-Kickback, False Claims Laws

In addition to FDA restrictions on marketing of pharmaceutical products, several other types of state and federal laws have been

applied to restrict certain marketing practices in the pharmaceutical industry in recent years. These laws include anti-kickback statutes, false
claims statutes, and other statutes pertaining to health care fraud and abuse. The federal healthcare program anti-kickback statute prohibits,
among other things, knowingly and willfully offering, paying, soliciting or receiving remuneration to induce, or in return for, purchasing,
leasing, ordering or arranging for the purchase, lease or order of any healthcare item or service reimbursable under Medicare, Medicaid, or
other federally financed healthcare programs. The Patient Protection and Affordable Care Act, as amended by the Health Care and
Education Reconciliation Act, collectively, the Healthcare Reform Act, amended the intent element of the federal statute so that a person or
entity no longer needs to have actual knowledge of the statute or specific intent to violate it. This statute has been interpreted to apply to
arrangements between pharmaceutical manufacturers on the one hand and prescribers, purchasers, and formulary managers on the other.
Violations of the anti-kickback statute are punishable by imprisonment, criminal fines, civil monetary penalties, and exclusion from
participation in federal healthcare programs. Although there are a number of statutory exemptions and regulatory safe harbors protecting
certain common activities from prosecution or other regulatory sanctions, the exemptions and safe harbors are drawn narrowly, and
practices that involve remuneration intended to induce prescribing, purchases, or recommendations may be subject to scrutiny if they do not
qualify for an exemption or safe harbor.

Federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to

the federal government, or knowingly making, or causing to be made, a false statement to have a false claim paid. This includes claims
made to programs where the federal government reimburses, such as Medicaid, as well as programs where the federal government is a
direct purchaser, such as when it purchases off the Federal Supply Schedule. Recently, several pharmaceutical and other healthcare
companies have been prosecuted under these laws for allegedly inflating drug prices they report to pricing services, which in turn were used
by the government to set Medicare and Medicaid reimbursement rates, and for allegedly providing free product to customers with the
expectation that the customers would bill federal programs for the product.

20

Table of Contents

In addition, certain marketing practices, including off-label promotion, may also violate false claims laws. Additionally, the

Healthcare Reform Act amended the federal false claims law such that a violation of the federal healthcare program anti-kickback statute
can serve as a basis for liability under the federal false claims law. The majority of states also have statutes or regulations similar to the
federal anti-kickback law and false claims laws, which apply to items and services reimbursed under Medicaid and other state programs, or,
in several states, apply regardless of the payor.

Other federal statutes pertaining to healthcare fraud and abuse include the civil monetary penalties statute, which prohibits the

offer or payment of remuneration to a Medicaid or Medicare beneficiary that the offeror/payor knows or should know is likely to influence
the beneficiary to order a receive a reimbursable item or service from a particular supplier, and the healthcare fraud statute, which prohibits
knowingly and willfully executing or attempting to execute a scheme to defraud any healthcare benefit program or obtain by means of false
or fraudulent pretenses, representations, or promises any money or property owned by or under the control of any healthcare benefit
program in connection with the delivery of or payment for healthcare benefits, items, or services.

Other Federal and State Regulatory Requirements

The Centers for Medicare & Medicaid Services, or CMS, has issued a final rule that implements a statutory requirement under the

Healthcare Reform Act that requires applicable manufacturers of drugs, devices, biologicals, or medical supplies that are covered under
Medicare, Medicaid, or the Children’s Health Insurance Program, or CHIP, to begin collecting and reporting annually information on
payments or transfers of value to physicians and teaching hospitals, as well as investment interests held by physicians and their immediate
family members. Manufacturers had to begin collecting information in 2013, with the first reports due in 2014. On September 30, 2014,
CMS posted the first round of data in searchable form on a public website. Failure to submit required information may result in civil
monetary penalties.

In addition, several states now require prescription drug companies to report expenses relating to the marketing and promotion of
drug products and to report gifts and payments to individual physicians in these states. Other states prohibit various other marketing-related
activities. Still other states require the posting of information relating to clinical trials and their outcomes. In addition, California,
Connecticut, Nevada, and Massachusetts require pharmaceutical companies to implement compliance programs and/or marketing codes.
Several additional states are considering similar proposals. Compliance with these laws is difficult and time consuming, and companies that
do not comply with these state laws face civil penalties.

Europe and Rest of the World Regulation

In addition to regulations in the United States, we will be subject to a variety of regulations in other jurisdictions both due to our
location and the fact that we are engaging in clinical programs outside of the United States and will want to obtain worldwide regulatory
approval for our TCR therapeutic candidates. In particular we have clinical trials ongoing in the United Kingdom and Spain and will be
subject to regulations relating to performance of those clinical trials and manufacture and supply of our SPEAR T-cells and patient
materials in the United Kingdom and Spain. Prior to supplying any TCR therapeutic candidate in any country or starting any clinical trials
in any country outside of the United States we must obtain the requisite approvals from regulatory authorities in such countries. The
existence of a United States regulatory approval does not guarantee that regulatory approvals will be obtained in other countries in which
we wish to conduct clinical trials or market our TCR therapeutic candidates. In the European Union, 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 prior to any clinical trial being conducted in the relevant country. A marketing authorization application is then submitted to
the EMA for approval by the European Commission. Finally, prior to any commercial supply, a pricing and reimbursement application is
submitted to each relevant country’s national or local health authority(ies).

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 are conducted in accordance with Good

21

Table of Contents

Clinical Practice (“GCP”) and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of
Helsinki. However, the interpretation of these requirements may well differ from country to country.

Review and Approval of Drug Products outside of the United States

In order to market any product outside of the United States, a company must also comply with numerous and varying regulatory
requirements of other countries and jurisdictions regarding quality, safety and efficacy and governing, among other things, clinical trials,
marketing authorization, commercial sales and distribution of products. Whether or not it obtains FDA approval for a product, the company
would need to obtain the necessary approvals by the comparable foreign regulatory authorities before it can commence clinical trials or
marketing of the product in those countries or jurisdictions. The approval process ultimately varies between countries and jurisdictions and
can involve additional product testing and additional administrative review periods. The time required to obtain approval in other countries
and jurisdictions might differ from and be longer than that required to obtain FDA approval. Regulatory approval in one country or
jurisdiction does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country or
jurisdiction may negatively impact the regulatory process in others.

Procedures Governing Approval of Products in the European Union

Pursuant to the European Clinical Trials Directive, a system for the approval of clinical trials in the European Union has been

implemented through national legislation of the member states. Under this system, an applicant must obtain approval from the competent
national authority of a European Union member state in which the clinical trial is to be conducted. Furthermore, the applicant may only start
a clinical trial after a competent ethics committee has issued a favorable opinion. Clinical trial application must be accompanied by an
investigational medicinal product dossier with supporting information prescribed by the European Clinical Trials Directive and
corresponding national laws of the member states and further detailed in applicable guidance documents.

To obtain marketing approval of a product under European Union regulatory systems, an applicant must submit a marketing

authorization application, or MAA, either under a centralized or decentralized procedure. The centralized procedure provides for the grant
of a single marketing authorization by the European Commission that is valid for all European Union member states. The centralized
procedure is compulsory for specific products, including for medicines produced by certain biotechnological processes, products designated
as orphan medicinal products, advanced therapy medicinal products and products with a new active substance indicated for the treatment of
certain diseases. For products with a new active substance indicated for the treatment of other diseases and products that are highly
innovative or for which a centralized process is in the interest of patients, the centralized procedure may be optional.

Under the centralized procedure, the Committee for Medicinal Products for Human Use, or the CHMP, established at the EMA is 

responsible for conducting the scientific assessment of a product. The CHMP is also responsible for several post-authorization and 
maintenance activities, such as the assessment of modifications or extensions to an existing marketing authorization.  For advanced therapy 
medicinal products (ATMPs), the scientific evaluation of MAA is primarily performed by the Committee for Advanced Therapies (CAT).  
The CAT prepares a draft opinion of each ATMP subject to a MAA which is sent for final approval to the CHMP.  

Under the centralized procedure in the European Union, the maximum timeframe for the evaluation of an MAA is 210 days,

excluding clock stops, when additional information or written or oral explanation is to be provided by the applicant in response to questions
of the CHMP. Accelerated evaluation might be granted by the CHMP in exceptional cases, when a medicinal product is of major interest
from the point of view of public health and in particular from the viewpoint of therapeutic innovation. In this circumstance, the EMA
ensures that the opinion of the CHMP is given within 150 days. Then, the European Commission grants or refuses the marketing
authorization, following a procedure that involves representatives of the member states. The Commission's decision is in accordance with
the CHMP's assessment except in very rare cases.

Marketing authorization is valid for five years in principle and the marketing authorization may be renewed after five years on the
basis of a re-evaluation of the risk-benefit balance by the EMA or by the competent authority of the authorizing member state. To this end,
the marketing authorization holder must provide the EMA or the competent

22

Table of Contents

authority with a consolidated version of the file in respect of quality, safety and efficacy, including all variations introduced since the
marketing authorization was granted, at least six months before the marketing authorization ceases to be valid. Once renewed, the
marketing authorization is valid for an unlimited period, unless the Commission or the competent authority decides, on justified grounds
relating to pharmacovigilance, to proceed with one additional five-year renewal. Any authorization which is not followed by the actual
placing of the drug on the EU market (in case of centralized procedure) or on the market of the authorizing member state within three years
after authorization ceases to be valid (the so-called sunset clause).

Legal Proceedings and Related Matters

From time to time, we may be party to litigation that arises in the ordinary course of our business. We do not have any pending

litigation that, separately or in the aggregate, would, in the opinion of management, have a material adverse effect on our results of

As of December 31, 2019, we had 400 employees. Of these employees, 315 were in research and development (including in

manufacturing and operations, and quality control and quality assurance) and 85 were in management and administrative functions
(including business development, finance, intellectual property, information technology and general administration). We have never had a
work stoppage and none of our employees are covered by collective bargaining agreements or represented by a labor union. We believe our
employee relations are good.

Risks Related to Our Financial Condition and Capital Requirements

We are a clinical-stage biopharmaceutical company with no commercial products and prediction of future performance is very difficult.

We are a clinical-stage biopharmaceutical company focused on novel cancer immunotherapy products. We have no products or

therapeutics approved for commercial sale and have not generated any revenue from product supplies or royalties. Our therapeutic
candidates, in particular our SPEAR T-cells, are new and largely unproven. 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. Our inability to
address these risks successfully would have a materially adverse effect on our business and prospects.

We have incurred net losses every year since our inception and expect to continue to incur net losses in the future.

We have generated losses since our inception in 2008, during which time we have devoted substantially all of our resources to

research and development efforts relating to our SPEAR T-cells and other cell therapies (including the NY-ESO SPEAR T-cell), including
engaging in activities to manufacture and supply our SPEAR T-cells for clinical trials in compliance with current good manufacturing
practice, or cGMP, conducting clinical trials of our SPEAR T-cells, providing general and administrative support for these operations and
protecting our intellectual property. We do not have any products approved for sale and have not generated any revenue from product
supplies or royalties. Based on our current plans, we do not expect to generate product or royalty revenues unless and until we obtain
marketing approval for, and commercialize, any of our SPEAR T-cells or other cell therapies.

For the years ended December 31, 2019, 2018, 2017, 2016 and the six months ended December 31, 2015 and the year ended
June 30, 2015, we incurred net losses of $137.2 million, $95.5 million, $70.1 million, $71.6 million, $23.0 million and $22.1 million,
respectively. As of December 31, 2019, we had accumulated losses of $455.7 million. We expect to continue incurring significant losses as
we continue with our research and development programs and to incur general and administrative costs associated with our operations. The
extent of funding required to develop our product candidates is difficult to estimate given the novel nature of our cell therapies and their un-
proven route to market. Our profitability is dependent upon the successful development, approval, and commercialization of our SPEAR T-
cells and other cell therapies, further development of the NY-ESO SPEAR T-cells by GSK (given the NY-ESO program has now been
transitioned to GSK), achieving GSK milestones (for both the NY-ESO program, the third SPEAR T-cell program and any future SPEAR
T-cell programs under the GSK Collaboration and License Agreement), progression of programs under the agreement with Universal Cells
Inc. and achieving a level of revenues adequate to support our cost structure. We may never achieve profitability, and unless and until we
do, we will continue to need to raise additional cash or alternative funding.

Although our financial statements have been prepared on a going concern basis, if we fail to obtain additional financing in future, this
may raise substantial doubt about our ability to continue as a going concern in future reporting periods

As of December 31, 2019, the Company had cash and cash equivalents of $50.4 million, marketable securities of $39.1 million,

and stockholders’ equity of $123.6 million. During the year ended December 31, 2019, the Company incurred a net loss of $137.2 million,
used cash of $112.5 million in its operating activities, and generated revenues of $1.1 million. The Company has incurred net losses in most
periods since inception and it expects to incur operating losses in future periods. On January 13, 2020, the Company entered into a co-
development and co-commercialization agreement with Astellas Pharma, Inc. (the “Astellas Collaboration Agreement”). The Company
received an upfront payment of $50.0 million in January 2020 under the agreement and is entitled to receive research funding of up to $7.5
million per year. Additional milestones are possible under the agreement, but these are dependent on the success of the development and
commercialization of research and products. In addition, on January 24, 2020, the Company closed an underwritten public offering of
21,000,000 American Depository Shares (ADSs) which, together with the full exercise by the underwriters on February 7, 2020, of their
option to purchase an additional 3,150,000 ADSs, generated net proceeds of approximately $89.8 million. We believe that our Total
Liquidity, combined with the upfront payment and

24

Table of Contents

the recently completed public offering of ADSs described above, will be sufficient to fund our operations, based upon our currently
anticipated research and development activities and planned capital spending, into the second half of 2021.

Management considers that there are no conditions or events, in the aggregate, that raise substantial doubt about the entity’s ability

to continue as a going concern for a period of at least one year from the date the financial statements are issued.

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

We have no cell therapies approved for commercial sale, have not generated any revenue from sales of our cell therapies, and do
not anticipate generating any revenue from sales of our cell therapies until sometime after we receive regulatory approval, if at all, for the
commercial sale of a cell therapy. We intend to fund future operations through milestone payments under our collaboration and license
agreements with GSK and Universal Cells Inc. and through additional equity financings or other third party collaborations. Our ability to
generate revenue and achieve profitability depends on our success in many factors, including:

●

●

●

●

●

●

●

●

●

●

●

●

completing preclinical development and advancing our SPEAR T-cells and other cell therapies to clinic;

delivering on the clinical development strategy for our SPEAR T-cells and other cell therapies;

progressing our clinical trials within predicted timeframes and without any substantial delays, for example as may be caused by
delays in patient recruitment, regulatory requirements to hold or suspend any clinical trials or delays in obtaining approvals
required to conduct clinical trials;

demonstrating a favorable benefit (efficacy parameters): risk (safety) for our SPEAR T-cells and the NY-ESO SPEAR T-cell
that translate into a differentiated product of value for patients;

obtaining data from clinical trials which are ongoing for SPEAR T-cells other than the NY-ESO SPEAR T-cell;

obtaining regulatory approvals and marketing authorizations for our SPEAR T-cells and the NY-ESO SPEAR T-cell for which
we or our collaborator complete clinical trials;

developing sustainable and scalable manufacturing and supply processes for our cell therapies, including establishing and
maintaining commercially viable supply relationships with third parties and establishing our own commercial manufacturing
capabilities and infrastructure;

developing a reliable and commercially viable/cost effective commercial manufacturing process to enable commercial supply
of our cell therapies;

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

obtaining market acceptance, pricing and reimbursement of our SPEAR T-cells and other cell therapies as viable treatment
options;

addressing any competing technological and market developments;

identifying, assessing, acquiring and/or developing new cell therapies including new SPEAR T-cells;

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

how; and

25

Table of Contents

●

attracting, hiring and retaining qualified personnel.

Even if one or more of the SPEAR T-cells is approved for commercial sale, we anticipate incurring significant costs associated
with commercializing any approved SPEAR T-cell. Our expenses could increase beyond expectations if the FDA or any other regulatory
agency requires changes to our manufacturing processes or assays, or for us to perform preclinical programs and clinical or other types of
trials in addition to those that we currently anticipate. If we are successful in obtaining regulatory approvals to market one or more SPEAR
T-cells, our revenue will be dependent, in part, upon the size of the markets in the territories for which we gain regulatory approval, the
accepted price for the SPEAR T-cell, the ability to get reimbursement at any price, and whether we own the commercial rights for that
territory. If the number of our addressable disease patients is not as significant as we estimate, the indication approved by regulatory
authorities is narrower than we expect, or the reasonably accepted population for treatment is narrowed by competition, physician choice or
treatment guidelines, we may not generate significant revenue from sales or supplies of such SPEAR T-cells, even if approved. If we are
not able to generate revenue from the sale of any approved SPEAR T-cells, we may never become profitable.

If we fail to obtain additional financing, we may be unable to complete the development and commercialization of our SPEAR T-cells.

Our operations have required substantial amounts of cash since inception. We expect to continue to spend substantial amounts to
continue the development of our SPEAR T-cells, including future clinical trials. If we receive approval for any of our SPEAR T-cells, we
will require significant additional amounts in order to launch and commercialize these therapeutic candidates.

As of December 31, 2019, we had $50.4 million of cash and cash equivalents and $39.1 million of marketable securities. We
expect to use these funds to advance and accelerate the clinical development of our SPEAR T-cells, to further develop and enhance our
manufacturing capabilities and secure a commercially viable manufacturing platform for all of our SPEAR T-cells, to advance additional
SPEAR T-cells into preclinical testing and progress such SPEAR T-cells through to clinical trials as quickly as possible and to fund
working capital, including for other general corporate purposes. Changing circumstances beyond our control, including changes to the scope
and timing of the programs under the GSK collaboration (for example, nomination of further targets by GSK or changes to the third target
program) or data seen in any of our clinical trials may cause us to increase our spending significantly faster than we currently anticipate. We
will require additional capital for the further development and commercialization of our SPEAR T-cells in accordance with currently
planned operations.

We cannot be certain that additional funding will be available on acceptable terms, or at all. We have no committed source of

additional capital and if we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to
significantly delay, scale back or discontinue the development or commercialization of our SPEAR T-cells, cell therapies or other research
and development initiatives. Our license and supply agreements may also be terminated if we are unable to meet the payment obligations
under these agreements. We could be required to seek collaborators for our SPEAR T-cells at an earlier stage than otherwise would be
desirable or on terms that are less favorable to us than might otherwise be available or relinquish or license on unfavorable terms our rights
to our SPEAR T-cells in markets where we otherwise would seek to pursue development or commercialization ourselves. Any of the above
events could significantly harm our business, prospects, financial condition and results of operations and cause the price of our American
Depositary Shares, or ADSs, to decline.

Raising additional capital may cause dilution to our existing shareholders, restrict our operations or require us to relinquish rights to
our technologies or product candidates.

We may seek additional capital through a combination of public and private equity offerings, debt financings, strategic

partnerships and alliances and licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible
debt securities, your ownership interest will be diluted, and the terms may include liquidation or other preferences that adversely affect your
rights as a shareholder. The incurrence of indebtedness would result in increased fixed payment obligations and could involve certain
restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire or license intellectual
property rights and other

26

Table of Contents

operating restrictions that could adversely impact our ability to conduct our business. If we raise additional funds through strategic
partnerships and alliances and licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies or
product candidates, or grant licenses on terms unfavorable to us.

Risks Related to the Development of Our SPEAR T-cells

Our business is highly dependent on our wholly owned SPEAR T-cell candidates including ADP-A2M4, ADP-A2M4CD8, and ADP-
A2AFP, which will require significant additional clinical testing before we can seek regulatory approval and begin commercialization of
any of our SPEAR T-cells.

There is no guarantee that any SPEAR T-cells will achieve regulatory approval or proceed to the next stage of clinical programs.

The process for obtaining marketing approval for any candidate is very long and risky and there will be significant challenges for us to
address in order to obtain marketing approval, if at all.

There is no guarantee that the results obtained in current clinical trials for our ADP-A2M4, ADP-A2M4CD8, and ADP-A2AFP

SPEAR T-cells will be sufficient for us to plan one or more pivotal clinical trials and obtain regulatory approval or marketing authorization.
Negative results in any SPEAR T-cell clinical program (including in any program using the NY-ESO SPEAR T-cell) may also impact our
ability to obtain regulatory approval for other SPEAR T-cells or other cell therapies, either at all or within anticipated timeframes because,
although the SPEAR T-cell may target a different cancer peptide, the underlying technology platform and other aspects of our clinical
programs are the same or substantially similar for all of our SPEAR T-cells and may be the same for certain other cell therapies.
Accordingly, a failure or delay in any one program may affect the ability to obtain regulatory approval to continue or conduct clinical
programs for other SPEAR T-cells or related cell therapies.

The data produced in our ongoing clinical trials is at an early stage and future data may not show responses in patients treated or
support continued progression of any of our therapies through development.

The patient response data that has been reported in our ADP-A2M4 trials (other than for synovial sarcoma), ADP-A2AFP trials
and ADP-A2M4CD8 trials represents data from individual patients within each study at the applicable dosing level. As such, the data is
initial data and we cannot know at this stage whether any patient who has seen a response will continue to respond favorably to our therapy
or that any response will persist. In addition, given the data is initial single patient data, there is no assurance that we will see responses in
any other patients or that such patients will not suffer severe adverse events which may result in a delay or halt to any clinical trial. Further
data is required in order to determine whether any specific SPEAR T-cell is able to be further developed, proceed to the next stage of
clinical program and in particular whether any SPEAR T-cell will achieve regulatory approval

We plan to provide further data updates as and when the applicable data is believed to be sufficiently mature. We do not, however,
intend to update patient response information on a frequent basis or as and when we obtain further patient information. Given the nature of
T-cell therapies and the time taken to observe patient responses to our SPEAR T-cells, we cannot provide any assurance that further data
updates will be provided frequently or that such data updates will be available at any particular time.

Negative results in any SPEAR T-cell clinical program may also impact our ability to obtain regulatory approval for other SPEAR

T-cells, either at all or within anticipated timeframes because, although the SPEAR T-cell may target a different cancer peptide, the
underlying technology platform and other aspects of our clinical programs are the same or substantially similar for all of our SPEAR T-
cells. Accordingly, a failure or delay in any one program may affect the ability to obtain regulatory approval to continue or conduct clinical
programs for other SPEAR T-cells.

We may not be able to submit INDs, or the foreign equivalent outside of the United States, to commence additional clinical trials for cell
therapies on the timeframes we expect, and even if we are able to, the FDA or comparable foreign regulatory authorities may not permit
us to proceed with planned clinical trials.

Progression of new cell therapies, including other SPEAR T-cells, into clinical trials is inherently risky and dependent on the

results obtained in preclinical programs, the results of other clinical programs and results of third-party

27

Table of Contents

programs that utilize common components, such as production of the lentiviral vector lot used for production and administration of our
SPEAR T-cell. If results are not available when expected or problems are identified during any cell therapy development, we may
experience significant delays in development of pipeline products and in existing clinical programs, which may impact our ability to receive
regulatory approval. This may also impact our ability to achieve certain financial milestones and the expected timeframes to market any of
our SPEAR T-cells. Failure to submit further IND or the foreign equivalent and commence additional clinical programs will significantly
limit our opportunity to generate revenue.

There is no guarantee that the FDA, or any other regulatory authority, will approve any IND (or equivalent application) for any of

our future cell therapies, or for new indications for our SPEAR T-cells already in clinical trials, or that amendments to existing protocols
will not be required. For example, we amended the protocols for all of our pending and on-going ADP-A2M4 and ADP-A2M10 clinical
trials in response to reported serious adverse events of prolonged serious pancytopenia in our clinical trials for ADP-A2M4 and ADP-
A2M10 in two patients treated with the highest lymphodepletion regimen. Such protocol amendments may delay our clinical trials, may
require changes or resubmission of our INDs, or may result or be related to a halt in our planned or contemplated clinical trials.

We are continuing to expand our clinical trial footprint in Europe. This requires gaining the approval of country specific review

bodies for GMO application and Clinical Trial Application (“CTA”). As this is not a harmonized process, the requirements can vary
considerably, and delays can be incurred at a country level. For example the information required in relation to manufacturing processes or
assays may differ between countries and required additional testing to be conducted in order for approval to be obtained.

In the USA, some institutional review boards, or IRBs, have requested that the Sponsor obtain Investigational Device Exemptions

(IDE) from the FDA for the validated clinical trial assay being used to select patients. This has delayed the initiation of some sites and
limited the ability to obtain high risk biopsies until an IDE has been granted. We plan to proactively seek IDEs for our SPEAR T-cell and
other cell therapy assays where appropriate.

Our cell therapies being developed may have potentially fatal cross-reactivity to other peptides or protein sequences within the human
body.

One of our prior SPEAR T-cells, designed to target an HLA-1 restricted MAGE-A3 cancer-specific peptide, recognized another

unrelated peptide from a protein called TITIN, expressed within normal cardiac and other muscle tissues in patients. As a result of this
cross-reactivity to the TITIN protein in the heart, two patients died during our MAGE-A3 clinical program, the program was put on pause,
then formally placed on hold by the FDA, after which we terminated the program. We subsequently developed a preclinical safety testing
program that identifies potential cross-reactivity risks but there may be gaps or other problems detected in the testing program at a later
date. Even with the use of this testing program, there can be no guarantee that the FDA will permit us to begin clinical trials of any
additional SPEAR T-cells other than those for which INDs already exist or that other off-target cross-reactivity will not be identified or
present in any patient group. Failure to develop an effective preclinical safety testing program will prevent or delay clinical trials of any
SPEAR T-cell. Detection of any cross-reactivity will halt or delay any ongoing clinical trials for any SPEAR T-cell and prevent or delay
regulatory approval. Given that the underlying technology platform, manufacturing process and development process is similar or has
shared elements for all of our cell therapies, issues pertaining to cross-reactivity for one SPEAR T-cell may impact our ability or our
collaborator’s ability to obtain regulatory approval for other cell therapies undergoing development and clinical trials, which would
significantly harm our business, prospects, financial condition and results of operations.

Cross-reactivity or allo-reactivity (binding to peptides presented on other HLA types) could also occur where the affinity-enhanced

engineered TCR contained within any cell therapy including SPEAR T-cells binds to peptides presented by HLAs other than the HLA type
for which the relevant TCR was developed. We have developed a preclinical screening process to identify allo-reactivity risk, however it is
not possible to identify all potential risks or to screen all HLA types. Where any allo-reactivity risk is identified, patients with the allo-
reactive alleles will be excluded from the trial. Any allo-reactivity or other cross-reactivity that impacts patient safety could materially
impact our ability to advance our SPEAR T-cells into clinical trials or to proceed to market approval and commercialization. In addition,
there is no guarantee that exclusion of patients with the identified allo-reactive allele will successfully eliminate the risk

28

Table of Contents

of allo-reactivity, and serious side effects for patients may still exist. Given that the underlying technology platform, manufacturing process
and development process are similar or shared for all of our cell therapies, issues pertaining to allo-reactivity for one SPEAR T-cell may
impact our ability or our collaborator’s ability to obtain regulatory approval for other cell therapies undergoing development and clinical
trials, which would significantly harm our business, prospects, financial condition and results of operations.

Our T-cell therapy, which is a type of cell therapy that uses gene therapy technology, represents a novel approach to cancer treatment
that could result in heightened regulatory scrutiny, delays in clinical development, or delays in our or our collaborator’s ability to
achieve regulatory approval or commercialization of cell therapies including our SPEAR T-cells.

Use of any of our cell therapies to treat a patient requires the use of gene therapy technology, which involves combining a

patient’s T-cells with our lentiviral delivery vector or other vector containing the gene for our affinity-enhanced engineered receptor or
TCR. This is a novel treatment approach that carries inherent development risks. We are therefore constantly evaluating and adapting our
cell therapies following the results obtained during development work and the clinical programs. Further development, characterization and
evaluation may be required, depending on the results obtained, in particular where such results suggest any potential safety risk for patients.
The need to develop further assays, or to modify in any way the protocols related to our cell therapies to improve safety or effectiveness,
may delay the clinical program, regulatory approval or commercialization, if approved at all, of any cell therapy. Consequently, this may
have a material impact on our ability to receive milestone payments and/or generate revenue from our SPEAR T-cells or other cell
therapies.

In addition, given the novelty of our cell therapies, the end users and medical personnel require a substantial amount of education
and training in their administration of cell therapies. Regulatory authorities have very limited experience with commercial engineered cell
therapies and SPEAR T-cells for the treatment of cancer. As a result, regulators may be more risk adverse or require substantial dialogue
and education as part of the normal regulatory approval process for each stage of development of any cell therapy. To date, only a limited
number of gene therapy products have been approved in the United States and European Union. Consequently, it is difficult to predict and
evaluate what additional regulatory hurdles may apply to the development of our cell therapies and whether additional investment, time or
resources will be required to overcome any such hurdles.

Additionally, because our technology involves the genetic modification of patient cells ex-vivo using a viral vector, we are subject

to many of the challenges and risks of gene therapy, including the following challenges:

● Regulatory requirements governing gene and cell therapy products have changed frequently and may continue to change in the

future.

● Random gene insertion associated with retrovirus-mediated genetically modified products, known as insertional oncogenesis,
could lead to lymphoma, leukemia or other cancers, or other aberrantly functioning cells. Insertional oncogenesis was seen in
early gene therapy studies conducted outside of the United States in 2003. In those studies, insertional oncogenesis resulted in
patients developing leukemia following treatment with the relevant gene therapy, with one patient dying. As a result of the data
from those studies, the FDA temporarily halted gene therapy trials in the United States. The previous trials involved
modification of stem cells rather than T-cells and utilized a murine gamma-retroviral vector rather than a lentiviral vector. We
cannot guarantee that insertional oncogenesis resulting from administration of our SPEAR T-cells or other cell therapies will
not occur.

● Although our viral vectors are not able to replicate, there may be a risk with the use of retroviral or lentiviral vectors that they

could undergo recombination and lead to new or reactivated pathogenic strains of virus or other infectious diseases.

●

There is the potential for delayed adverse events following exposure to gene therapy products due to persistent biological
activity of the genetic material or other components of products used to carry the genetic material. In part for this reason, the
FDA recommends a 15-year follow-up observation period for

29

Table of Contents

all surviving patients who receive treatment using gene therapies in clinical trials. We may need to adopt such an observation
period for our therapeutic candidates; however, the FDA does not require that the tracking be complete prior to its review of
the Biologics License Application, or BLA.

● Clinical trials using genetically modified cells may be subject to additional or further regulatory processes, for example by the
NIH Office of Biotechnology Activities’ Recombinant DNA Advisory Committee, or RAC or the need to apply for a specific
applications relating to the use of Genetically Modified Organism application in the European Union. These additional
processes may delay or impede the initiation of a clinical trial.

If adverse events of the type described above were to occur, further advancement of our clinical trials could be halted or delayed,

which would have a material adverse effect on our business and operations. In addition, heightened regulatory scrutiny of gene therapy
product candidates may result in delays and increased costs in bringing a product candidate to market, if at all. 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 revenue in the future.

In addition, results seen in third party clinical trials using other cell therapy products, for example CAR-T products, or in clinical

trials conducted by our collaborators may impact on the further advancement of our clinical trials.

Results seen in third party clinical trials using products that are also used in our combination clinical trials, may impact on the

further advancement of our similar clinical trials or clinical trials of our collaborators where similar product types are used.

T-cell therapy is a novel approach to cancer treatment that creates significant increased risk in terms of side-effect profile, ability to
satisfy regulatory requirements associated with clinical trials and the long- term viability of administered SPEAR T-cells or other cell
therapies.

Development of a pharmaceutical or biologic therapy or product has inherent risks based on differences in patient population and

responses to therapy and treatment. The mechanism of action and impact on other systems and tissues within the human body following
administration of our cell therapies is not completely understood, which means that we cannot predict the long-term effects of treatment
with any of our cell therapies (whether by us or a collaborator). In addition, it is not possible for any pre-clinical safety package to
completely identify all potential safety risks.

We are aware that certain patients do not respond to our SPEAR T-cells and that other patients may relapse or cease to present the

peptide being targeted by such SPEAR T-cells. The percentage of the patient population in which these events may occur is unknown, but
the inability of patients to respond and the possibility of relapse may impact our or our collaborator’s ability to conduct clinical trials, to
obtain regulatory approvals, if at all, and to successfully commercialize any SPEAR T-cell.

Clinical trials using our SPEAR T-cell therapeutics are still in the early stages, and it is difficult to predict the results that will be

obtained by us or our collaborator in ongoing clinical trials or the next phase or phases of any clinical program. It is also difficult to predict
the way in which SPEAR T-cells or other cell therapies will interact with third-party products used in combination clinical trials. Any
undesirable side effects seen in combination trials may affect our ability or our collaborator’s ability to continue with and obtain regulatory
approval for any combination therapy and may also impact our or our collaborator’s ability to continue with and obtain regulatory approval
for the cell therapies alone.

There is a significant risk at each stage of any clinical program that serious adverse events or low efficacy, as well as less

favorable benefit:risk profiles, will prevent any SPEAR T-cell program from proceeding further or will result in those programs being
suspended or placed on hold (whether voluntarily or as a result of a regulatory authority requirement). For example, there is a risk that the
target (or similar) peptide to which any SPEAR T-cell is directed may be present in both patients’ cancer cells and other non-cancer cells
and tissues. Should this be the case, patients may suffer a range of side effects associated with the SPEAR T-cell binding to both the cancer
cells and/or other cells and tissues and such side effects could cause patient death. The extent of these side effects will depend on which
cells and tissues are affected as well as the degree to which the target (or similar) peptide is expressed in these cells and tissues.

30

Table of Contents

Serious adverse events seen with other immunotherapy products, such as the severe neurotoxicity events observed with CD19-directed
CAR-T cell treatments, may also occur at any stage of the clinical program. Further, following infusion of any SPEAR T-cells, there may
be a transient inflammatory reaction of the disease to the treatment. Symptoms in any given subject would be dependent on the location and
other characteristics of their tumor. For example, subjects with lung tumors may experience dyspnea. Cardiac toxicities may be observed in
patients with pre-existing cardiac or pericardial masses. These inflammatory reactions and related symptoms may be mild and self-limited,
but can be severe, potentially life-threatening and require medical intervention.

As of January 10, 2020, for ADP-A2AFP, ADP-A2M4, and ADP-A2M10:

arthralgia, and pleural effusion. Two subjects have had treatment related fatal SAE reports - one subject experienced prolonged
pancytopenia/aplastic anemia and the other experienced a cerebrovascular accident (stroke).

The adverse events occurring in >10% of subjects treated with ADP-A2M10 and considered by investigators to be at least
possibly related to ADP-A2M10 include leukopenia/white blood cells decreased, lymphopenia/lymphocyte count decreased,
thrombocytopenia/platelet count decreased, pyrexia, CRS, peripheral edema, chills, and rash. Serious adverse events reported
with ADP-A2M10 in two or more subjects whether considered related to the SPEAR T-cells or not include sepsis, CRS, rash,
and acute kidney injury. One subject had a treatment related fatal SAE of prolonged pancytopenia with aplastic anemia
following treatment with a second infusion of ADP-A2M10.

● As of February 3, 2020, for ADP-A2M4CD8, there have been no reports of SAEs. One subject experienced Grade 1 CRS.

As noted above, there were two SAE reports of severe prolonged pancytopenia with aplastic anemia (one patient receiving ADP-

A2M4 and one patient receiving ADP-A2M10) considered by the investigator to be probably related to the SPEAR T-cells and to the
lymphodepleting chemotherapy. Both of these patients died from complications of aplastic anemia related to the severe prolonged
pancytopenia. In another patient, there was one report of Grade 3 neurotoxicity considered by the investigator to be probably related to the
ADP-A2M4 SPEAR T-cells and, in the same patient, a later grade 5 SAE of stroke that was considered by the investigator to be possibly
related to the product. These reports were communicated to the FDA and we have responded to queries from the FDA in relation to these
reports. All three patients received the highest lymphodepletion regimen (fludarabine 30 mg/m2/day for 4 days and cyclophosphamide 1800
mg/m2/day for 2 days). The protocols for all of our ADP-A2M4 and ADP-A2M10 trials have now been amended to mitigate the future risk
of prolonged pancytopenia and stroke, including a reduction of the lymphodepletion regimen to a previously used regimen (fludarabine 30
mg/m2/day for 4 days and cyclophosphamide 600 mg/m2/day for 3 days) to mitigate prolonged pancytopenia, and exclusion of patients
with a prior history of stroke

31

Table of Contents

or central nervous system bleeding (or transient ischemic attack (TIA) or reversible ischemic neurologic deficit (RIND) within the prior 6
months of treatment) to mitigate the risk of stroke. These protocol changes have been communicated to and acknowledged by the FDA. If
further adverse events of a similar nature occur in patients, there is a risk that we or the FDA may impose a clinical hold until the adverse
events are further evaluated or, alternatively, we or the FDA may suspend or require termination of these clinical trials.

Validation of our cell therapies requires access to human samples but there is no guarantee that such samples can be obtained or, if
they can be obtained, that the terms under which they are provided will be favorable to us.

Certain of the steps involved in validating and carrying out safety testing in relation to our cell therapies require access to samples

(e.g., tissues samples or cell samples) from third parties. Such samples may be obtained from universities or research institutions and will
often be provided, subject to satisfaction of certain terms and conditions. There can be no guarantee that we will be able to obtain samples
in sufficient quantities to enable development of and use of the full preclinical safety testing program for all cell therapies undergoing
research and development. In addition, the terms under which such samples are available may not be acceptable to us or may restrict our
use of any generated results or require us to make payments to the third parties.

Our cell therapies and their application are not fully scientifically understood and are still undergoing validation and investigation.

Cell therapies including our SPEAR T-cells and their potential associated risks are still under investigation. There is no guarantee
that any of our cell therapies including our SPEAR T-cells will work in the way that we currently anticipate or that affinity modification of
the receptors within T-cells or other cellular therapies will produce the anticipated enhancements in activity. For example, there is a
potential risk that, given that the TCR chains in our SPEAR T-cells are produced separately and then assembled within patient T-cells into
full TCRs, the TCR chains from both transduced and naturally occurring T-cells could be assembled into an unintended end TCR due to
mispairing of TCR chains, which could create unknown recognition and cross-reactivity problems within patients. Although this
phenomenon has not been reported in humans, it remains a theoretical risk for our SPEAR T-cells and other similar cell therapies and is
still being studied and investigated. This could delay regulatory approval, if any, for the relevant cell therapy. To the extent that any
mispairing is identified, either in our or our competitors’ clinical trials, additional investment may be required in order to modify relevant
cell therapies and to further assess and validate the risk of such mispairing to patients. There is also no guarantee that following
modification of the relevant SPEAR T-cell or other cell therapy, such modified cell therapy will remain suitable for patient treatment, that it
will eliminate the risk of mispairing of TCR chains or that regulatory approval will be obtained at all or on a timely basis in relation to such
modified cell therapy. The occurrence of such events would significantly harm our business, prospects, financial condition and results of
operations.

We may not be able to identify and validate additional target peptides or isolate and develop affinity-enhanced TCRs that are suitable
for validation and further development.

The success of our cell therapies depends on both the identification of target peptides presented on cancer cells, which can be

bound by our cell therapy products, and isolation and affinity enhancement of receptors including TCRs, which can be used to treat patients
if regulatory approval is obtained. There is an inherent risk that the number of target peptides that can be identified and/or our ability to
develop and isolate suitable receptors for affinity enhancement could be significantly lower than projected or that no additional cell
therapies suitable for further development can be identified. Any failure to identify and validate further target peptides will reduce the
number of potential SPEAR T-cells and other cell therapies that we can successfully develop, which in turn will reduce the commercial
opportunities available to us and increase our reliance on our existing SPEAR T-cells.

In addition, there is no guarantee that our attempts to develop further SPEAR T-cells will result in candidates for which the safety

and efficacy profiles enable progression to and through preclinical testing. Failure to identify further candidates for progression into
preclinical testing and clinical programs will significantly impact our commercial returns, increase our reliance on the success of our
existing SPEAR T-cell programs and may significantly harm our business, prospects, financial condition and results of operations. If
resources become limited or if we fail to identify suitable

32

Table of Contents

target peptides, receptors including TCRs or affinity-enhanced receptors, our ability to submit INDs for further cell therapies may be
delayed or never realized, which would have a materially adverse effect on our business. We have multiple research projects ongoing both
internally and with third parties, for example Universal Cells, Inc., Noile-Immune Biotech, Inc., Alpine Immune Sciences Inc. and
Bellicum, Inc. The outcomes of these research projects are uncertain and such research projects may or may not generate cell therapies with
profiles suitable for further development or progression into clinical trials.

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

Conduct of clinical trials is dependent on finding clinical sites prepared to carry out the relevant clinical trials, screening of patients

by the clinical sites, recruitment of patients both in terms of number and type of patients and general performance of the relevant clinical
site. It is difficult to predict how quickly we or our collaborators will be able to recruit suitable patients, find suitable sites, begin clinical
programs and administer our cell therapies including our SPEAR T-cells. The patient population in which any required peptide antigen is
presented may be lower than expected which will increase the timescales required to find and recruit patients into the applicable clinical
trial. Screening of a large number of patients is required to identify HLA and tumor antigen positive patients for all of our clinical trials with
our SPEAR T-cells. Any delay in identification of suitable patients will result in the Company incurring additional costs associated with the
need to find and initiate additional clinical trial sites. It is also difficult to predict whether changes may be required to any clinical trial
design as our clinical trials progress. The need to make changes to any clinical trial design can result in delays to the performance of that
clinical trial whilst any changes are approved and implemented at applicable clinical trial sites.

Our and our collaborator’s clinical trials will compete with other clinical trials that are in the same therapeutic areas as our cell

therapies, which 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. In addition, GSK is also opening T-cell therapy clinical
trials in synovial sarcoma and MRCLS in the U.S. and European Union which could impact the number of sites available to us to run our
ADP-A2M4 trials in the same indications and the number and types of patients in these indications available to us. Because the number of
qualified clinical investigators is limited, we will conduct some of our clinical trials at the same clinical trial sites where competing trials are
ongoing, which will reduce the number of patients who are available for our clinical trials at such clinical trial sites. Moreover, because our
cell therapies represent a departure from more commonly used methods for cancer treatment, potential patients and their physicians may
opt to use conventional therapies, such as chemotherapy and hematopoietic cell transplantation, rather than enrollment in any of our current
or future clinical trials. This may also mean we cannot recruit patients at a suitable time in their disease progression. In addition, in relation
to any indication, the standard of care for patients in that indication may change or further develop meaning that clinical sites are no longer
prepared to continue with any clinical trial or require amendments to agreed protocols for clinical trials. For example, the standard of care in
melanoma changed during the course of our clinical trials in melanoma with the NY-ESO SPEAR T-cell and as a result the clinical trial was
halted due to anticipated unavailability of patients. Such circumstances can lead to the suspension of the relevant clinical trial at a site,
inability to recruit further patients at that clinical site or a requirement to amend the protocol, all of which will delay or potentially halt
progression of a cell therapy through clinical trials.

Even if we are able to enroll a sufficient number of patients in our clinical trials, delays in patient enrollment may result, and have
resulted in, increased costs or may affect the timing or outcome of the planned clinical trials, which could prevent completion of these trials
and adversely affect our and our collaborator’s ability to advance the development of our SPEAR T-cells and other cell therapies.

Comparability studies related to the manufacturing of any cell therapies may be required ahead of any pivotal trial start date or

ahead of use in the European Union or alternatively in connection with any changes made to our manufacturing process, including changes
in certain third party suppliers. The requirement to carry out such comparability studies or other similar studies may delay the uptake of any
changed process, start of any pivotal trial or use of the relevant cell therapy. If the results from the comparability studies are not acceptable,
this may further delay

33

Table of Contents

the start of such trials or changed process and require re-evaluation of the process used to manufacture of such cell therapy.

We may not be able to develop or obtain approval for the analytical assays and companion diagnostics required for commercialization
of our cell therapies including ADP-A2M4.

Administration of our cell therapies requires the use of an immuno-chemistry or other screening assay in which patients are
screened for the presence of the cancer peptide targeted by our cell therapies. For example, in our ADP-A2M4 trial patients are screened for
the presence of MAGE-A4. This assay requires the identification of suitable antibodies which can be used to identify the presence of the
relevant target cancer peptide.

If safe and effective use of a biologic product depends on an in vitro diagnostic, such as a test to detect patients with a particular
cancer peptide, then the FDA generally requires approval or clearance of the diagnostic, known as a companion diagnostic, concurrently
with approval of the therapeutic product. To date, the FDA has generally required in vitro companion diagnostics that are intended for use
in selection of patients who will respond to cancer treatment to obtain a pre-market approval, or PMA, which can take up to several years,
for that diagnostic approval or clearance to occur simultaneously with approval of the biologic product.

We expect that, for all our cell therapies, the FDA and similar regulatory authorities outside of the United States will require the

development and regulatory approval of a companion diagnostic assay as a condition to approval. We also expect that the FDA may require
PMA supplemental approvals for use of that same companion diagnostic as a condition of approval of additional cell therapies. We do not
have experience or capabilities in developing or commercializing these companion diagnostics and plan to rely in large part on third parties
to perform these functions.

If we or our collaborators, or any third parties that we engage to assist us, are unable to successfully develop companion diagnostic
assays for use with any SPEAR T-cells, or are unable to obtain regulatory approval or experience delays in either development or obtaining
regulatory approval, we may be unable to identify patients with the specific profile targeted by the relevant cell therapy for enrollment in
our clinical trials. In addition, delay in development and approval of any companion diagnostic may also impact our ability to obtain a
marketing approval for the therapeutic product and to commercialize the therapeutic product. For example, delays in the development of a
companion diagnostic for detection of the MAGE-A4 antigen in synovial sarcoma and MRCLS may result in delays to any marketing
approval for ADP-A2M4. Accordingly, further investment may be required to further develop or obtain the required regulatory approval for
the relevant companion diagnostic assay, which would delay or substantially impact our ability or our collaborators’ ability to conduct
further clinical trials or obtain regulatory approval.

Manufacturing and administering cell therapies is complex and we and our collaborators may encounter difficulties in production,
particularly with respect to process development or scaling up manufacturing capabilities. If we or our collaborators encounter such
difficulties, our or our collaborators’ ability to provide supply of our cell therapies for clinical trials or for commercial purposes could
be delayed or stopped.

The process of manufacturing and administering cell therapies is complex and highly regulated. The manufacture of cell therapies
including our SPEAR T-cells involves complex processes, including manufacture of a lentiviral delivery vector containing the gene for our
affinity-enhanced engineered receptor. Administration of SPEAR T-cells includes harvesting white blood cells from the patient, isolating
certain T-cells from the white blood cells, combining patient T-cells with our lentiviral delivery vector through a process known as
transduction, expanding the transduced T-cells to obtain the desired dose, and ultimately infusing the modified T-cells back into the patient.
As a result of the complexities, our manufacturing and supply costs are likely to be higher than those at more traditional manufacturing
processes and the manufacturing process is less reliable and more difficult to reproduce.

Delays or failures in the manufacture of cell therapies (whether by us, any collaborator or our third party contract manufacturers)

can result in a patient being unable to receive their cell therapy or a requirement to re-manufacture which itself then causes delays in
manufacture for other patients. Any delay or failure or inability to

34

Table of Contents

manufacture on a timely basis can adversely affect a patient’s outcomes and delay the timelines for our clinical trials. Such delays or failure
or inability to manufacture can result from:

● A failure in the manufacturing process itself for example by an error in manufacturing process (whether by us or our third party

contract manufacturing organization), equipment or reagent failure, failure in any step of the manufacturing process, failure to
maintain a GMP environment, failure in quality systems applicable to manufacture, sterility failures, contamination during
process;

● A lack of reliability or reproducibility in the manufacturing process itself leading to variability in end manufacture of cell

therapy. Should the process be unreliable, the relevant regulatory agency (for example the FDA in the United States) may place
a hold on a clinical trial or request further information on the process which could in turn result in delays to the clinical trials;

● Variations in patient starting material or apheresis product resulting in less product than expected or product which is not

viable, or which cannot be used to successfully manufacture a cell therapy;

●

●

●

●

Product loss or failure due to logistical issues including issues associated with the differences between patients’ white blood
cells or characteristics, interruptions to process, contamination, failure to supply patient apheresis material within required
timescales (for example as a result of an import or export hold-up) or supplier error;

Inability to obtain manufacturing slots from third party contract manufacturers or to have enough manufacturing slots
(including those at our Navy Yard facility) to manufacture cell therapies for patients as and when those patients require
manufacture;

Inability to procure starting materials or to manufacture starting materials (including at our UK vector facility), for example
vector required for SPEAR T-cell manufacture;

Loss of or close-down of any manufacturing facility used in the manufacture of our cell therapies. For example, we will be
manufacturing cell therapies at our Navy Yard manufacturing facility. Should there be a contamination event at the facility
resulting in the close-down of that facility it may not be possible to find alternative manufacturing capability for these cell
therapies within the timescales required for ongoing clinical trials. In addition, as with many pharmaceutical manufacturing
facilities, the facility will have periods of time within which it cannot be used for manufacture of patient product to enable
routine checks to be performed on the facility;

●

Loss or contamination of patient starting material, requiring the starting material to be obtained again from the patient or the
manufacturing process to be re-started; and

● A requirement to modify or make changes to any manufacturing process. Such changes may additionally require comparability
testing which then may reduce the amount of manufacturing slots available for manufacture of our cell therapies. Delays in our
ability to make the required modifications or perform any required comparability testing within currently anticipated
timeframes or that such modifications or comparability testing, when made, will obtain regulatory approval or that the new
processes or modified processes will successfully be transferred to the third party contract suppliers within currently anticipated
timeframes can also impact timelines for manufacture.

The requirements for manufacture and supply of cell therapies for clinical trials in Europe have additional complexities and the

manufacture and supply of cell therapies is raising issues which have not previously been regulated or observed by the relevant regulatory
authorities. For example, supply of SPEAR T-cells for European clinical trials will either require manufacture of SPEAR T-cells in the
United States or use of a new CMO in Europe. Where manufacture continues in the United States, there is a need to transfer patient product
from clinical sites in Europe to the manufacturer in the United States, for the patient product to be converted into our end SPEAR T-cell
product, for that

35

Table of Contents

product to be released for use in Europe and then for that SPEAR T-cell product to be transported back to the site in Europe for
administration to the patient. The supply and manufacturing chain required to achieve this is very complex and could be subject to failures
at any point in the supply and manufacturing chain. Any inability to set up acceptable manufacturing and supply chains to enable treatment
of patients in Europe could result in a delay to those trials starting in Europe or could result in a delay in patient treatment, requirement to
re-apherese a patient or a requirement to re-manufacture patient material.

As our cell therapies progress through preclinical programs and clinical trials towards approval and commercialization, it is

expected that various aspects of the manufacturing and administration process will be altered in an effort to optimize processes and results.
We have already identified some improvements to our manufacturing and administration processes, but these changes may not achieve the
intended objectives, may not be transferable to third parties or able to be used at larger scales and could cause our cell therapies to perform
differently or affect the results of planned clinical trials or other future clinical trials. In addition, such changes may require amendments to
be made to regulatory applications or comparability tests to be conducted which may further delay the timeframes under which modified
manufacturing processes can be used for any cell therapy. If cell therapies manufactured under the new process have a worse safety or
efficacy profile than the prior investigational product or the process is less reproducible than the previous process, we may need to re-
evaluate the use of that manufacturing process, which could significantly delay or even result in the halting of our clinical trials.

Developing a commercially viable process is a difficult and uncertain task, and there are risks associated with scaling to the level
required for advanced clinical trials or commercialization, including, among others, increased costs, potential problems with process scale-
out, process reproducibility, stability issues, lot consistency, loss of product, and timely availability of reagents or raw materials or contract
manufacturing services or facilities. A failure to develop such a commercially viable process within anticipated timescales may prevent or
delay progression of our T-cell therapies into pivotal clinical trials and ultimately commercialization. In addition, we may ultimately be
unable to reduce the expenses associated with our SPEAR T-cells to levels that will allow us to achieve a profitable return on investment.

We have a platform process which may enable us to treat patient populations with an ‘off-the-shelf’ product. We have entered into
an alliance with Universal Cells, Inc. to further develop that platform process. However, there is no guarantee that our research program or
the research program with Universal Cells, Inc. will be successful, will be carried out within the timescales currently anticipated, or even if
successful will result in a cell therapy that can be used to treat patients or that such cell therapy will allow us to achieve a profitable return
on investment.

We have insurance to cover certain business interruption events which is capped at £10 million in the United Kingdom and $5

million in the United States. However, because our level of insurance is capped, it may be insufficient to fully compensate us if any of these
events were to occur in the future.

Our manufacturing process needs to comply with FDA regulations and foreign regulations relating to the quality and reliability of such
processes. Any failure to comply with relevant regulations could result in delays in or termination of our clinical programs and
suspension or withdrawal of any regulatory approvals.

In order to commercially produce our products, we will need to comply with the FDA’s and other regulatory authorities’ cGMP
requirements at our Navy Yard facility, vector facility and third party contract manufacturing facilities. We may encounter difficulties in
achieving quality control and quality assurance and may experience shortages in qualified personnel. We and our third party contract
manufacturers are subject to inspections by the FDA and comparable agencies in other jurisdictions to confirm compliance with applicable
regulatory requirements once the process has been approved. Any failure to follow cGMP or other regulatory requirements, reliably
manufacture product or delay, interruption or other issues that arise in the manufacture, fill- finish, packaging, or storage of our cell
therapies as a result of a failure of our facilities or the facilities or operations of third parties to comply with regulatory requirements or pass
any regulatory authority inspection could significantly impair our ability to develop and commercialize our cell therapies, including leading
to significant delays in the availability of our cell therapies for our clinical trials or the termination of or suspension of a clinical trial, or the
delay or prevention of a filing or approval of marketing authorization applications for our cell therapies. Significant non-compliance could
also result in the imposition of sanctions, including warning letters, fines, injunctions, civil penalties, failure of regulatory authorities to

36

Table of Contents

grant marketing approvals for our cell therapies, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of
products, operating restrictions and criminal prosecutions, any of which could damage our reputation and our business.

Given we now manufacture cell therapies at our own US manufacturing facility and plan to manufacture vector at a UK vector

facility, there is no guarantee that regulatory authorities will not raise non-compliance issues or that regulatory authorities may require us to
make changes to the way in which either facility is operated. This may result in a delay in our ability to manufacture cell therapies at our
own facility or in our ability to supply vector material for use in the manufacturing process. In addition, there is no guarantee that any cell
therapy or vector produced in any of our facilities will be able to meet regulatory requirements or that we will be able to recruit and
maintain sufficient staff to enable manufacture of products within required timescales. Resourcing of cell manufacturing facilities is
increasingly competitive, which restricts the number of available skilled operators which can be recruited at our manufacturing facilities.
Any failure to meet regulatory requirements or produce cell therapies and vector according to regulatory requirements could result in delays
to our clinical programs, potential side effects and even fatalities to patients and may result in withdrawal of regulatory approval for our
manufacturing facility.

The outcome of clinical trials is uncertain and clinical trials may fail to demonstrate adequately the safety and efficacy of any cell
therapies which would prevent or delay regulatory approval and commercialization.

There is a risk in any clinical trial (whether sponsored by us, a collaborator or investigator-initiated) that side effects from cell

therapies will require a hold on, or termination of, clinical programs or further adjustments to clinical programs in order to progress any cell
therapy. Our cell therapies are novel and unproven, and regulators will therefore require evidence that the cell therapies are safe before
permitting clinical trials to commence and evidence that the cell therapies are safe and effective before granting any regulatory approval. In
particular, because our cell therapies are subject to regulation as biological products, we will need to demonstrate that they are safe, pure
and potent for use in each target indication. Our cell therapy must demonstrate an acceptable benefit:risk profile in its intended patient
population and for its intended use. The benefit:risk profile required for product licensure will vary depending on these factors and may
include not only the ability to show tumor shrinkage, but also adequate duration of response, a delay in the progression of the disease and/or
an improvement in survival. For example, response rates from the use of the SPEAR T-cells may not be sufficient to obtain regulatory
approval unless we or our collaborators can also show an adequate duration of response.

The regulatory authorities (including the FDA) may issue a hold on our or our collaborators’ clinical trials as a result of safety

information and data obtained in third party clinical trials or in relation to third party products. Any such hold will require addressing by us
and our collaborators and will inevitably delay progression of the clinical trials concerned, if such clinical trials progress at all.

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. Success in preclinical programs and early clinical trials does not ensure that later clinical trials will be
successful. Moreover, the results of preclinical programs and early clinical trials of cell therapies may not be predictive of the results of
later-stage clinical trials. To date, we have only obtained interim results from Phase 1/2 clinical trials that are uncontrolled, involve small
sample sizes and are of shorter duration than might be required for regulatory approval. There may be other reasons why our early clinical
trials are not predictive of later clinical trials. In addition, the results of trials in one set of patients or line of treatment may not be predictive
of those obtained in another and protocols may need to be revised based on unexpected early results.

We expect there may be greater variability in results for cell therapies which are administered on a patient-by-patient basis than for

“off-the-shelf” products, like many other biologics. There is typically an extremely high rate of attrition from the failure of any products
proceeding through clinical trials. Cell therapies in later stages of clinical trials may fail to show the desired safety and efficacy profile
despite having progressed through preclinical programs 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 or unacceptable safety issues, notwithstanding
promising results in earlier trials. Most biologic candidates that begin clinical trials are never approved by regulatory authorities for

37

Table of Contents

commercialization. We cannot therefore guarantee that we will be successful in demonstrating the required efficacy and safety profile from
the performance of any of our clinical programs.

Certain of our clinical trials include dose escalation studies in which the dose of cell therapies administered to patients is varied or
initial studies in which the pre-treatment regimen may be varied, for example a regimen with and without fludarabine. The outcome of such
dose escalation or initial studies will inform the clinical study going forward. However, the need to carry out dose escalation or other initial
studies may result in delays in data from such clinical programs while the most suitable dose or regimen is assessed. For example, the trial
design for our SPEAR T-cell trials includes dose escalation and therefore efficacy data may not be obtained from initial patients treated in
such studies during the dose escalation phase.

In addition, even if such trials are successfully completed, we cannot guarantee that the FDA or foreign regulatory authorities will

interpret the results as we or our collaborators do. Accordingly, more trials may be required before we can submit any cell therapy for
regulatory 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 authorization application, we may be required to expend significant resources, which may not be available to us, to conduct
additional trials in support of potential approval of our cell therapies. We cannot predict whether any of our cell therapies will satisfy
regulatory requirements at all or for indications in which such cell therapies are currently being evaluated as part of any clinical programs.

We have limited experience conducting later stage clinical trials which may cause a delay in any clinical program and in the obtaining
of regulatory approvals.

Although we have recruited a team that has significant experience with clinical trials, as a company we have limited experience in

conducting clinical trials through to regulatory approval. In part because of this lack of experience, we cannot be certain that planned
clinical trials will begin or be completed on time, if at all. Large-scale trials would require significant additional financial and management
resources, and reliance on third-party clinical investigators, contract research organizations, or CROs, or consultants. Relying on third-party
clinical investigators, consultants or CROs may force us to encounter delays that are outside of our control.

Cell therapies may have undesirable side effects or have other properties that could halt their clinical development, prevent their
regulatory approval, limit their commercial potential or otherwise result in significant negative consequences.

Where any cell therapy has undesirable side effects, regulatory approval for such therapeutic may be delayed or suspended, or

alternatively may be restricted to particular disease indications or states that are more limited than desirable. This could result in the failure
of any products reaching the market or a reduction in the patient population for which any cell therapy can be used.

As of January 10, 2020, for ADP-A2AFP, ADP-A2M4, and ADP-A2M10:

●

●

The adverse events occurring in >10% of subjects treated with ADP-A2AFP and considered by investigators to be at least
possibly related to ADP-A2AFP include neutropenia/neutrophil count decreased, leukopenia/white blood cell count decreased,
lymphopenia/lymphocyte count decreased, thrombocytopenia/platelet count decreased, hypoalbuminemia, febrile neutropenia,
pyrexia, increase in alanine aminotransferase, increase in aspartate aminotransferase, increase in alkaline phosphatase, diarrhea,
vomiting, CRS, dyspepsia, hyperkalemia, lethargy, cognitive disorder, hypotension, pain in extremity, and muscular weakness.
Serious adverse events reported with ADP-A2AFP whether considered related to the SPEAR T-cells or not include CRS, bile
duct obstruction and abdominal pain.

The adverse events occurring in >10% of subjects treated with ADP-A2M4 and considered by investigators to be at least
possibly related to ADP-A2M4 include neutropenia/neutrophil count decreased, thrombocytopenia/platelet count decreased,
lymphopenia/lymphocyte count decreased, anemia/red blood cells decreased, febrile neutropenia, CRS, fatigue, pyrexia,
decreased appetite, rash, dyspnea, sinus

tachycardia/tachycardia, hypophosphatemia, headache, nausea, vomiting, increase in aspartate aminotransferase, increase in
alanine aminotransferase, chills, diarrhea, hypotension, and tumor pain. Serious adverse events reported with ADP-A2M4 in
two or more subjects whether considered related to the SPEAR T-cells or not include CRS, lung infection, sepsis, pyrexia,
pancytopenia, atrial fibrillation, neurotoxicity, thrombocytopenia/platelet count decreased, arthralgia, and pleural effusion. Two
subjects have had treatment related fatal SAE reports - one subject experienced prolonged pancytopenia/aplastic anemia and
the other experienced a cerebrovascular accident (stroke).

●

The adverse events occurring in >10% of subjects treated with ADP-A2M10 and considered by investigators to be at least
possibly related to ADP-A2M10 include leukopenia/white blood cells decreased, lymphopenia/lymphocyte count decreased,
thrombocytopenia/platelet count decreased, pyrexia, CRS, peripheral edema, chills, and rash. Serious adverse events reported
with ADP-A2M10 in two or more subjects whether considered related to the SPEAR T-cells or not include sepsis, CRS, rash,
and acute kidney injury. One subject had a treatment related fatal SAE of prolonged pancytopenia with aplastic anemia
following treatment with a second infusion of ADP-A2M10.

● As of February 3, 2020, for ADP-A2M4CD8, there have been no reports of SAEs. One subject experienced Grade 1 CRS.

As noted above, there were two SAE reports of severe prolonged pancytopenia with aplastic anemia (one patient receiving ADP-

A2M4 and one patient receiving ADP-A2M10) considered by the investigator to be probably related to the SPEAR T-cells and to the
lymphodepleting chemotherapy. Both of these patients died from complications of aplastic anemia related to the severe prolonged
pancytopenia. In another patient, there was one report of Grade 3 neurotoxicity considered by the investigator to be probably related to the
ADP-A2M4 SPEAR T-cells and, in the same patient, a later grade 5 SAE of stroke that was considered by the investigator to be possibly
related to the product. These reports were communicated to the FDA and we have responded to queries from the FDA in relation to these
reports. All three patients received the highest lymphodepletion regimen (fludarabine 30 mg/m2/day for 4 days and cyclophosphamide 1800
mg/m2/day for 2 days). The protocols for all of our ADP-A2M4 and ADP-A2M10 trials have now been amended to mitigate the future risk
of prolonged pancytopenia and stroke, including a reduction of the lymphodepletion regimen to a previously used regimen (fludarabine 30
mg/m2/day for 4 days and cyclophosphamide 600 mg/m2/day for 3 days) to mitigate prolonged pancytopenia, and exclusion of patients
with a prior history of stroke or central nervous system bleeding (or transient ischemic attack (TIA) or reversible ischemic neurologic deficit
(RIND) within the prior 6 months of treatment) to mitigate the risk of stroke. These protocol changes have been communicated to and
acknowledged by the FDA. If further adverse events of a similar nature occur in patients, there is a risk that we or the FDA may impose a
clinical hold until the adverse events are further evaluated or, alternatively, we or the FDA may suspend or require termination of these
clinical trials.

CRS has been reported in subjects in our SPEAR T-cell trials. A subset of these reported CRS events has been Grade 3 or 4 in

severity. Subjects with more severe CRS symptoms have generally responded to treatment with the anti-IL6 or anti-IL6 receptor therapy.
All of our protocols now allow for use of this therapy for the treatment of cytokine release syndrome. The anti-IL6 receptor antibody
(tocilizumab) has been shown to control cytokine release syndrome without abrogating the anti-tumor response.

Any unacceptable toxicities arising in ongoing clinical programs could result in suspension or termination of those clinical
programs. The more SAEs that are reported the greater the risk of suspension of termination of clinical programs, even where the SAEs are
unrelated to each other or to our cell therapies. Any suspension or termination may affect other SPEAR T-cells and thereby impact our
ability to recognize any product revenues. Any side effects may also result in the need to perform additional trials, which will delay
regulatory approval for such cell therapies, if at all, and require additional resources and financial investment to bring the relevant cell
therapy to market.

In addition, the impact of cell therapies may vary from patient to patient and this may affect the number of patients who can be

successfully treated with our cell therapies. Depending on the nature of the indication, certain patients may need to be excluded from
treatment, which could also impact our ability to delivery therapies to some patients.

39

Table of Contents

Use of cell therapies in combination with other third party products or therapies may increase or exacerbate side effects that have

been seen with our cell therapies alone or may result in new side effects that have not previously been identified with our cell therapies
alone. Any undesirable side effects seen in combination trials may affect our ability to continue with and obtain regulatory approval for the
combination therapy, but may also impact our ability to continue with and obtain regulatory approval for our cell therapies alone.

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

Clinical trials, depending on the stage, can be costly as well as difficult to implement and define, particularly with technologies

that are not tried and tested, such as our cell therapies. These factors can lead to a longer clinical development timeline and regulatory
approval process, including a requirement to conduct further or more complex clinical trials in order to obtain regulatory approval.
Regulatory authorities may disagree with the design of any clinical program, and designing an acceptable program could lead to increased
timeframes for obtaining of approvals, if any. In addition, progression of clinical trials depends on the ability to recruit suitable patients to
those trials and delay in recruiting will impact the timeframes of such clinical trials and as a result the timeframes for obtaining regulatory
approval, if any, for the relevant cell therapy.

In particular, eligible patients must be screened for the target peptide and HLA type, which may reduce the number of patients

who can be recruited for any clinical program. For example, low target peptide expression levels in the NY-ESO SPEAR T-cell and ADP-
A2M10 programs affected speed of patient recruitment in certain of the clinical trials. The ability to administer cell therapies to patients in
accordance with set protocols for the clinical trials and the results obtained depends on patient participation for the duration of the clinical
trial, which many of these patients are unable to do because of their late-stage cancer and limited life expectancy.

Although the initial results in our clinical trials to date may suggest a promising tolerability profile, these results may not be

indicative of results obtained in later and larger clinical trials. Long-term follow-up of patients from earlier trials may also result in
detection of additional side effects or identification of other safety issues. There is no guarantee of success in any clinical trial and there is a
very high attrition rate for pharmaceutical or biological compounds entering clinical trials. Any side effects or negative safety issues
identified at any stage of clinical development will require additional investigation and assessment which can result in additional costs and
resource requirements that could delay or potentially terminate our clinical trials.

We may face difficulty in enrolling patients in our clinical trials.

We or our collaborators may find it difficult to enroll patients in our clinical trials. Identifying and qualifying patients, including

testing of patients for appropriate target peptides and HLA type, to participate in clinical trials of our cell therapies are critical to our
success. The patient population in which any required peptide antigen is presented may be lower than expected which will increase the
timescales required to find and recruit patients into the applicable clinical trial. The timing of clinical trials depends on the speed at which
we or our collaborators can recruit patients to participate in testing of our cell therapies. If patients are unwilling to participate in trials
because of negative publicity from adverse events or for other reasons, including competitive clinical trials for similar patient populations,
negative results seen in competitive third party clinical trials utilizing similar cell therapy products, the timeline for recruiting patients,
conducting trials and obtaining regulatory approval of potential products may be delayed or prevented. These delays could result in
increased costs, delays in advancing product development, delays in testing the effectiveness of our technology or termination of the clinical
trials altogether. We or our collaborators may not be able to identify, recruit and enroll a sufficient number of patients, or those with
required or desired characteristics to achieve sufficient diversity in a given trial in order to complete our clinical trials in a timely manner.
Successful execution of patient treatment and assessment of outcomes is affected by several factors including:

●

eligibility criteria for the trial in question, in particular, presenting the correct HLA type and expression levels of the target
antigen;

●

ability to detect required expression levels of target antigens in any patient population;

40

ability to detect required target antigens in any patient population and to set detection levels at an appropriate level to facilitate
patient recruitment;

severity of the disease under investigation and the type of patient being recruited into the clinical trial;

design of the trial protocol;

size of the patient population;

perceived risks and benefits of the cell therapy under trial;

novelty of the cell therapy and acceptance by oncologists;

proximity and availability of clinical trial sites for prospective patients;

availability of competing therapies and clinical trials and ability to obtain patient insurance coverage;

efforts to facilitate timely enrollment in clinical trials and to provide manufactured product on a timely basis;

patient referral practices of physicians;

changes in the underlying standard of care applicable or treatments available for the relevant indication for which a patient is
being treated;

availability of reimbursement from insurance companies in relation to the costs of clinical trials using our cell therapies which
can vary between clinical sites; and

ability to monitor patients adequately during and after treatment, for example where patients decide not to attend follow-up
appointments.

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

or terminate ongoing or planned clinical trials, any of which would have an adverse effect on our business.

Our cell therapies for which we intend to seek approval as biologic products may face competition sooner than anticipated.

The enactment of the Biologics Price Competition and Innovation Act of 2009, or BPCIA, created an abbreviated pathway for the
approval of biosimilar and interchangeable biological products. The abbreviated 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 existing reference product. Under the BPCIA, an application for a biosimilar product cannot be approved by the FDA until 12 years after
the original branded product or “reference” is approved under a BLA. On March 6, 2015, the FDA approved the first biosimilar product
under the BPCIA. However, the law is complex and is still being interpreted and implemented by the FDA and as a result, its ultimate
impact, implementation and meaning are subject to uncertainty. While it is uncertain when such processes intended to implement 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.

There is a risk that the FDA will not consider our cell therapies to be reference products for competing products, potentially

creating the opportunity for generic competition sooner than anticipated. Additionally, this period of regulatory exclusivity does not apply
to companies pursuing regulatory approval via their own traditional BLA, rather than via the abbreviated pathway. Moreover, the extent to
which a biosimilar, once approved, will be substituted for any

41

Table of Contents

one of our 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.

Foreign countries also have abbreviated regulatory pathways for biosimilars and hence even where the FDA does not approve a
biosimilar biologic, a biosimilar could be approved using an abbreviated regulatory pathway in other markets where our cell therapies are
approved and marketed.

Risks Related to Government Regulation

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

We have not previously submitted a BLA to the FDA, or similar approval submissions to comparable foreign authorities. A BLA

must include extensive preclinical and clinical data and supporting information to establish the cell therapy’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 cell therapies including our SPEAR T-cells to create additional challenges in obtaining
regulatory approval, if at all. For example, the FDA has limited experience with commercial development of T-cell therapies for cancer.
Accordingly, the regulatory approval pathway for our SPEAR T-cells may be uncertain, complex, expensive and lengthy, and approval
may not be obtained. Requests for additional information can delay the start of any pivotal or other trial or result in clinical holds being
imposed on ongoing trials and there is no guarantee that the FDA will not continue to require further or additional information ahead of
approving any trial whether from our collaborators or from us.

We or our collaborators could also encounter delays if physicians encounter unresolved ethical issues associated with enrolling
patients in clinical trials of our cell therapies in lieu of prescribing existing treatments that have established safety and efficacy profiles.
Further, a clinical trial may be suspended or terminated by us or a collaborator, IRBs for the institutions in which such trials are being
conducted, the Data Monitoring Committee for such trial, or by the FDA or other regulatory authorities due to a number of factors,
including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical
trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues
or adverse side effects, failure to demonstrate a benefit from using a cell therapy, changes in governmental regulations or administrative
actions or lack of adequate funding to continue the clinical trial. If we or our collaborators experience termination of, or delays in the
completion of, any clinical trial of our cell therapies, the commercial prospects for our cell therapies 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 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 cell therapies.

The FDA regulatory process can be difficult to predict, in particular whether for example accelerated approval processes are available
or further unanticipated clinical trials are required will depend on the data obtained in our ongoing clinical trials.

The regulatory approval process and the amount of time it takes us to obtain regulatory approvals for our cell therapies will depend
on the data that are obtained in our ongoing clinical trials and in one or more future registration or pivotal clinical trials. We may attempt to
seek approval on a per indication basis for our cell therapies on the basis of a single pivotal trial or on the basis of data from a Phase 2 trial.
While the FDA requires in most cases two adequate and well-controlled pivotal clinical trials to demonstrate the efficacy of a product
candidate, a single trial with other confirmatory evidence may be sufficient in rare instances where the trial is a large multicenter trial
demonstrating internal consistency and a statistically very persuasive finding of a clinically meaningful effect on mortality, irreversible
morbidity or prevention of a disease with a potentially serious outcome and confirmation of the result in a second trial would be practically
or ethically impossible. Depending on the data we obtain, the FDA or other regulatory authorities may require additional clinical trials to be
carried out or further patients to be treated prior to the granting of any

42

Table of Contents

regulatory approval for marketing of our cell therapies. It is difficult for us to predict with such a novel technology exactly what will be
required by the regulatory authorities in order to take our cell therapies to market or the timeframes under which the relevant regulatory
approvals can be obtained.

We obtained breakthrough therapy status for the NY-ESO SPEAR T-cell for the treatment of certain patients with inoperable or

metastatic synovial sarcoma who have received prior chemotherapy. Following exercise of the option over the NY-ESO SPEAR T-cell
program by GSK, it is not known whether such breakthrough therapy status will continue or whether GSK will apply for and obtain any
accelerated approval for the NY-ESO SPEAR T-cell. In addition, we have obtained RMAT designation (Regenerative Medicine Advanced
Therapy designation) from the FDA for ADP-A2M4 for the treatment of synovial sarcoma. We may apply for similar status or accelerated
programs in other countries and for other of our products and indications. However, given the novel nature of our cell therapies , it is
difficult for us to predict or guarantee whether the FDA or other regulatory authorities will approve such requests or what further clinical or
other data may be required to support an application for such accelerated approval procedures.

The process of obtaining marketing approvals, both in the United States and in countries outside of the United States, is expensive,
may take many years if additional clinical trials are required, if approval is obtained at all, and can vary substantially based upon a variety of
factors, including the type, complexity and novelty of the cell therapies involved. For example, clinical trials may be required in pediatric
populations before any marketing approval can be obtained, which can be time consuming and costly. Changes in marketing approval
policies during the development period, changes in or the enactment of additional statutes or regulations, or changes in regulatory review for
each submitted product application, may cause delays in the approval or rejection of an application. The FDA and foreign regulatory
authorities also have substantial discretion in the drug and biologics approval process. The number and types of preclinical programs and
clinical trials that will be required for regulatory approval varies depending on the cell therapy, the disease or condition that the cell therapy
is designed to address, and the regulations applicable to any particular cell therapy. Approval policies, regulations or the type and amount of
clinical data necessary to gain approval may change during the course of a cell therapy’s clinical development and may vary among
jurisdictions, and there may be varying interpretations of data obtained from preclinical programs or clinical trials, either of which may
cause delays or limitations in the approval or the decision not to approve an application. In addition, approval of our cell therapies could be
delayed or refused for many reasons, including the following:

●

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

● we or our collaborators may be unable to demonstrate to the satisfaction of the FDA or comparable foreign regulatory

authorities that our SPEAR T-cells have a beneficial risk: benefit profile 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;

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

the data collected from clinical trials of our cell therapies 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;

our manufacturing processes or facilities or those of the third-party manufacturers we use may not be adequate to support
approval of our cell therapies; 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.

43

Table of Contents

It is possible that no cell therapies will ever obtain the appropriate regulatory approvals necessary to commercialize the TCR
therapeutics. Any delay in obtaining, or failure to obtain, required approvals would materially adversely affect our ability to generate
revenue from the particular cell therapy, which would result in significant harm to our business.

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

Obtaining and maintaining regulatory approval of our cell therapies in one jurisdiction does not guarantee that we or our
collaborators 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 SPEAR T-cell, comparable regulatory authorities in foreign jurisdictions must also approve the manufacturing,
marketing and promotion of the SPEAR T-cell 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
programs or clinical trials as clinical trials conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions.
In many jurisdictions outside the United States, a cell therapy must be approved for reimbursement before it can be approved for sale in that
jurisdiction. In some cases, the price that we or our collaborators intend to charge for our cell therapies is also subject to approval.

We or our collaborators may also submit marketing authorization applications in other countries. Regulatory authorities in
jurisdictions outside of the United States have requirements for approval of cell therapies 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 cell therapies in certain countries. For example, in
certain jurisdictions additional clinical trials in different patient populations may be required. 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 cell therapies will be harmed.

We may seek breakthrough therapy or fast track designations and may pursue accelerated approval for some or all of our current
SPEAR T-cells, but we may be unable to obtain such designations or, where obtained we may be unable to maintain breakthrough
therapy designation or, obtain or maintain the benefits associated with such designations.

We obtained breakthrough therapy status in the United States and PRIME status in Europe for the NY-ESO SPEAR T-cell for the

treatment of certain patients with inoperable or metastatic synovial sarcoma who have received prior chemotherapy. We have obtained
RMAT designation (Regenerative Medicine Advanced Therapy designation) from the FDA for ADP-A2M4 in synovial sarcoma. We may
seek breakthrough therapy or fast track designations for our other SPEAR T-cells in the United States or equivalent regulations elsewhere in
the world.

In 2012, the FDA established a breakthrough therapy designation which is intended to expedite the development and review of

products that treat serious or life-threatening diseases when “preliminary clinical evidence indicates that the drug may demonstrate
substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects
observed early in clinical development.” The designation of a SPEAR T-cell as a breakthrough therapy provides potential benefits that
include more frequent meetings with the FDA to discuss the development plan for the SPEAR T-cell and ensure collection of appropriate
data needed to support approval; more frequent written correspondence from the FDA about things such as the design of the proposed
clinical trials and use of biomarkers; intensive guidance on an efficient drug development program, beginning as early as Phase 1;
organizational commitment involving senior managers; and eligibility for rolling review and priority review.

Breakthrough therapy designation does not change the standards for product approval. There can be no assurance that we will

receive breakthrough therapy designation for any SPEAR T-cell or any particular indication. Additionally, other treatments from competing
companies may obtain the designations and impact our ability to develop and commercialize our SPEAR T-cells, which may adversely
impact our business, financial condition or results of operation.

44

Table of Contents

We may also seek fast track designation. If a drug or biologic candidate is intended for the treatment of a serious or life-threatening

condition or disease and the drug demonstrates the potential to address unmet medical needs for the condition, the sponsor may apply for
fast track designation. Under the fast track program, the sponsor of a new drug or biologic candidate may request that the FDA designate
the candidate for a specific indication as a fast track drug or biologic concurrent with, or after, the submission of the IND for the candidate.
The FDA must determine if the drug or biologic candidate qualifies for fast track designation within 60 days of receipt of the sponsor’s
request. Even if we do apply for and receive fast track designation, we may not experience a faster development, review or approval process
compared to conventional FDA procedures. The FDA may withdraw fast track designation if it believes that the designation is no longer
supported by data from our clinical development program.

We may also seek accelerated approval under the FDA’s fast track and accelerated approval programs, the FDA may approve a

drug or biologic for a serious or life-threatening illness that provides meaningful therapeutic benefit to patients over existing treatments
based upon 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. For
drugs granted accelerated approval, post-marketing confirmatory trials have been required to describe the anticipated effect on irreversible
morbidity or mortality or other clinical benefit. These confirmatory trials must be completed with due diligence. Moreover, the FDA may
withdraw approval of our SPEAR T-cell or indication approved under the accelerated approval pathway if, for example:

●

the trial or trials required to verify the predicted clinical benefit of our SPEAR T-cell fail to verify such benefit or do not
demonstrate sufficient clinical benefit to justify the risks associated with the drug;

●

other evidence demonstrates that our SPEAR T-cell is not shown to be safe or effective under the conditions of use;

● we fail to conduct any required post approval trial of our SPEAR T-cell with due diligence; or

● we disseminate false or misleading promotional materials relating to the relevant SPEAR T-cell.

In Europe, the EMA has implemented the so-called "PRIME" (PRIority MEdicines) status in order support the development and

accelerate the approval of complex innovative medicinal products addressing an unmet medical need. The PRIME status enables early
dialogue with the relevant EMA scientific committees and, possibly, some payers; and thus reinforces the EMA's scientific and regulatory
support. It also opens accelerated assessment of the marketing authorization application (150 days instead of 210 days). The PRIME status,
which is decided by the EMA, is reserved to medicines that may benefit from accelerated assessment, i.e. medicines of major interest from
a public health perspective, in particular from a therapeutic innovation perspective.

In 2016, the EMA granted PRIME status to NY-ESO SPEAR T-Cell for the treatment of certain patients with metastatic synovial
sarcoma who have received prior chemotherapy. We may apply for PRIME status for other of our SPEAR T-cell products. There can be no
assurance that any application will be successful in obtaining PRIME status.

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

Any regulatory approvals that we receive for our cell therapies will require surveillance to monitor the safety and efficacy of the
cell therapy. The FDA may also require a risk evaluation and mitigation strategy in order to approve our cell therapies, 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 cell therapies, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage,
advertising, promotion, import, export and recordkeeping for our cell therapies will be subject to extensive and ongoing regulatory
requirements. These

45

Table of Contents

requirements include submissions of safety and other post-marketing information and reports, registration and listing, as well as continued
compliance with cGMPs and cGCPs for any clinical trials that we conduct post-approval. We and our contract manufacturers will be subject
to periodic unannounced inspections by the FDA to monitor and ensure compliance with cGMPs. We must also comply with requirements
concerning advertising and promotion for any cell therapies for which we obtain marketing approval. Promotional communications with
respect to prescription drugs, including biologics, are subject to a variety of legal and regulatory restrictions and must be consistent with the
information in the product’s approved labeling. Thus, we will not be able to promote any cell therapies we develop for indications or uses
for which they are not approved. Later discovery of previously unknown problems with our cell therapies, including adverse events of
unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory
requirements, may result in, among other things:

●

●

●

●

●

●

restrictions on our ability to conduct clinical trials, including full or partial clinical holds on ongoing or planned trials;

restrictions on such products’ manufacturing processes;

restrictions on the marketing of a product;

restrictions on product distribution;

requirements to conduct post-marketing clinical trials;

untitled or warning letters;

● withdrawal of the products from the market;

●

●

●

●

●

●

●

●

●

refusal to approve pending applications or supplements to approved applications that we submit;

recall of products;

fines, restitution or disgorgement of profits or revenue;

suspension or withdrawal of regulatory approvals;

refusal to permit the import or export of our products;

product seizure;

injunctions;

imposition of civil penalties; or

criminal prosecution.

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 cell therapies. We cannot predict the likelihood, nature or extent of government
regulation that may arise from future legislation or administrative 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.

46

Table of Contents

In addition, if following any pivotal clinical trial we were able to obtain accelerated approval of any of our cell therapies, the FDA
will require us to conduct a confirmatory trial or trials to verify the predicted clinical benefit and additional safety studies. The results from
the confirmatory trial or trials may not support the clinical benefit, which would result in the approval being withdrawn.

We may seek a conditional marketing authorization in Europe for some or all of our current cell therapies, but we may not be able to
obtain or maintain such authorization.

As part of its marketing authorization process, the EMA may grant marketing authorizations for certain categories of medicinal
products on the basis of less complete data than is normally required, when doing so may meet unmet medical needs of patients and serve
the interest of public health. In such cases, it is possible for the Committee for Medicinal Products for Human Use, or CHMP, to
recommend the granting of a marketing authorization, subject to certain specific obligations to be reviewed annually, which is referred to as
a conditional marketing authorization. This may apply to medicinal products for human use that fall under the centralized procedure
(EMA's scientific assessment and European Commission's approval), including those that aim at the treatment, the prevention, or the
medical diagnosis of seriously debilitating diseases or life-threatening diseases and those designated as orphan medicinal products.

A conditional marketing authorization may be granted when the CHMP finds that, although comprehensive clinical data referring

to the safety and efficacy of the medicinal product have not been supplied, all the following requirements are met:

●

●

●

●

the risk: benefit balance of the medicinal product is positive;

it is likely that the applicant will be in a position to provide the comprehensive clinical data;

unmet medical needs will be fulfilled; and

the benefit to public health of the immediate availability on the market of the medicinal product concerned outweighs the risk
inherent in the fact that additional data is still required.

The granting of a conditional marketing authorization is restricted to situations in which only the clinical part of the application is

not yet fully complete. Incomplete preclinical or quality data may only be accepted if duly justified and only in the case of a product
intended to be used in emergency situations in response to public-health threats. Conditional marketing authorizations are valid for
one year, on a renewable basis. The holder will be required to complete ongoing trials or to conduct new trials with a view to confirming
that the benefit-risk balance is positive. In addition, specific obligations may be imposed in relation to the collection of pharmacovigilance
data.

Granting a conditional marketing authorization allows medicines to reach patients with unmet medical needs earlier than might otherwise
be the case and will ensure that additional data on a product are generated, submitted, assessed and acted upon. Although we may seek a
conditional marketing authorization for one or more of our cell therapies, the CHMP may ultimately not agree that the requirements for
such conditional marketing authorization have been satisfied. This would delay the commercialization of our cell therapies as we would
have to wait for a complete data package before submitting the marketing authorization application.

We or our collaborators may not be able to obtain or maintain orphan drug exclusivity for our cell therapies.

Regulatory authorities in some jurisdictions, including the United States and Europe, may designate drugs or biologics for
relatively small patient populations as orphan drugs. Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it
is a drug or biologic intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000
individuals in the United States or, if they affect more than 200,000 individuals in the United States, there is no reasonable expectation that
the cost of developing and making a drug product available in the United States for these types of diseases or conditions will be recovered
from sales of the product. If the FDA grants orphan drug designation, the identity of the therapeutic agent and its potential orphan use are

47

Table of Contents

disclosed publicly by that agency. Orphan drug designation does not convey any advantage in or shorten the duration of the regulatory
review and approval process, but it can lead to financial incentives, such as opportunities for grant funding toward clinical trial costs, tax
advantages in-lieu of R&D tax credits and user-fee waivers. If a product that has orphan drug designation subsequently receives the first
FDA approval for the disease or condition for which it has such designation, the product is entitled to orphan drug marketing exclusivity for
a period of seven years. Orphan drug marketing exclusivity generally prevents the FDA from approving another application, including a full
BLA, to market the same drug for the same indication for seven years, except in limited circumstances, including if the FDA concludes that
the later drug is clinically superior to the approved drug.

The European criteria for orphan designation are different from the U.S. criteria. On the one hand, the prevalence criterion is five

in 10,000 individuals in the European Economic Area (EU plus Iceland, Liechtenstein and Norway). On another hand, no therapy is
available for the rare condition or, if such a therapy exists, the future orphan product must bring a significant benefit over that therapy. The
significant benefit may be any benefit to patients, including improved safety, improved efficacy, better quality of life or better patient
compliance to treatment, provided that it is significant. It must be demonstrated by means of a comparison with the other available
therapies, including the medicinal products already approved for the same rare condition. The Committee for Orphan Medicinal Products, or
COMP, examines if the orphan criteria are met, and the orphan status is granted by a decision of the European Commission. The meeting of
the criteria for orphan designation is examined again by the COMP at the time of approval of the medicinal product. If the criteria for
orphan designation are no longer met at that time, the European Commission withdraws the orphan status.

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

which it has such designation, the product is entitled to a period of marketing exclusivity, which precludes the EMA or the FDA from
approving another marketing authorization application for the same drug for that time period. The applicable period is seven years in the
United States and 10 years in Europe. The European exclusivity period can be reduced to six years if a drug no longer meets the criteria for
orphan drug designation or if the drug is sufficiently profitable so that market exclusivity is no longer justified. Orphan drug exclusivity
may be lost if the FDA determines that the request for designation was materially defective or if the manufacturer is unable to assure
sufficient quantity of the drug to meet the needs of patients with the rare disease or condition. In Europe, the orphan exclusivity may be lost
vis-à-vis another drug in cases the manufacturer is unable to assure sufficient quantity of the drug to meet patient needs or if that other
product is proved to be clinically superior to the approved orphan product. A drug is clinically superior if it is safer, more effective or
makes a major contribution to patient care.

There can be no assurance that any of our cell therapies will be eligible for orphan drug designation in the United States or in other
jurisdictions or that it will obtain orphan drug marketing exclusivity upon approval or that we or GSK will not lose orphan drug designation
for ADP-A2M4 or the NY-ESO SPEAR T-cell. Inability to obtain orphan drug designation for a specific cell therapy or loss of such
designation for ADP-A2M4 or the NY-ESO SPEAR T-cell in the future would prevent any ability to take advantage of the financial
benefits associated with orphan drug designation and would preclude us from obtaining marketing exclusivity upon approval, if any. Even if
we obtain orphan drug exclusivity for a product, that exclusivity may not effectively protect the product from competition because different
drugs can be approved for the same condition. The extent of market exclusivity which is obtained may also be affected if the indication for
any relevant registration or pivotal trial is narrower than the orphan designation granted. Even after an orphan drug is approved, the FDA
can subsequently approve another drug for the same condition if the FDA concludes that the later drug is clinically superior in that it is
shown to be safer, more effective or makes a major contribution to patient care.

Any failure by us to comply with existing regulations could harm our reputation and operating results.

The production of cell therapies is highly regulated and subject to constant inspection. The regulatory environment may also

change from time to time. Any failure to comply with regulatory requirements, whether in the United States or in other countries in which
our cell therapies are supplied, may result in investigation by regulatory authorities, suspension of regulatory authorizations and, as a result,
suspension of clinical programs or ability to supply any of our cell therapies and potentially significant fines or other penalties being
imposed in relation to any breach. Any failure may also harm our reputation and impact our ability going forward to obtain regulatory
approvals for other cell

48

Table of Contents

therapies or require us to undertake additional organizational changes to minimize the risk of further breach. A failure to comply may apply
to any part of our business, for example to the processes used for manufacture of our cell therapies (including the reliability of the process)
or to the processes used for treatment of patients (including tracking of patient product and supply of patient specific product).

Because administration of cell therapies is patient-specific, the process requires careful handling of patient-specific products and

fail-safe tracking, namely the need to ensure that the tracking process is without error and that patient samples are tracked from patient
removal, through manufacturing and re-administration to the same patient. While such mechanisms are in place, should the tracking process
fail, whether at our own facility, a third party facility or at any point in the manufacturing and supply process, a patient could receive
another patient’s T-cells resulting in significant toxicity and potentially patient fatality. We will need to invest in enhanced systems, such as
bar coding, to further ensure fail safe tracking. There is always a risk of a failure in any such system. Inability to develop or adopt an
acceptable fail-safe tracking methodology and handling regime may delay or prevent us from receiving regulatory approval and/or result in
significant toxicity and potentially patient fatality if a patient receives another patient’s T-cells. This risk may be increased where cell
therapies are used in clinical programs that we do not control or sponsor and, should an error be made in the administration of our cell
therapies in such clinical programs, this could affect the steps required in our own clinical programs and manufacturing process requiring
the addition of further tracking mechanisms to ensure fail-safe tracking. The tracking systems required to further ensure safe patient
administration may also require increased administration to satisfy other regulatory requirements, for example data protection requirements
in Europe. The need to ensure tracking systems are adequate and to comply with these additional regulatory requirements may result in
delay to the start of trials or the need to obtain additional regulatory licenses or consents prior to starting such trials.

Our research and development activities utilize hazardous, radioactive and biological materials. Should such materials cause injury or
be used other than in accordance with applicable laws and regulations, we may be liable for damages.

We use hazardous and biological reagents and materials in our research and development at our U.K. site. We also use radioactive

reagents and materials in our research and development in the United Kingdom. We have obtained the appropriate certification or ensured
that such certification has been obtained as required for the use of these reagents but our use is subject to compliance with applicable laws
and there is a risk that should any third party or employee suffer injury or damage from radioactive, hazardous or biological reagents that
we may incur liability or obligations to compensate such third parties or employees. We have employer’s liability insurance capped at
£10.0 million per occurrence and public liability insurance capped at £3.0 million per occurrence; however, these amounts may be
insufficient to compensate us if these events actually occur in the future.

We are subject to the U.K. Bribery Act, the U.S. Foreign Corrupt Practices Act and other anti-corruption laws, as well as export control
laws, customs laws, sanctions laws and other laws governing our operations. If we fail to comply with these laws, we could be subject to
civil or criminal penalties, other remedial measures, and legal expenses, which could adversely affect our business, results of operations
and financial condition.

Our operations are subject to anti-corruption laws, including the U.K. Bribery Act 2010, or Bribery Act, the U.S. Foreign Corrupt
Practices Act, or FCPA, and other anti-corruption laws that apply in countries where we do business. The Bribery Act, the FCPA and these
other laws generally prohibit us and our employees and intermediaries from bribing, being bribed or making other prohibited payments to
government officials or other persons to obtain or retain business or gain some other business advantage. Under the Bribery Act, we may
also be liable for failing to prevent a person associated with us from committing a bribery offense. We and our commercial partners may
operate in a number of jurisdictions that pose a high risk of potential Bribery Act or FCPA violations, and we participate in collaborations
and relationships with third parties whose actions, if non-compliant, could potentially subject us to liability under the Bribery Act, FCPA or
local anti-corruption laws. In addition, we cannot predict the nature, scope or effect of future regulatory requirements to which our
international operations might be subject or the manner in which existing laws might be administered or interpreted.

49

Table of Contents

We are also subject to other laws and regulations governing our international operations, including regulations administered by the

governments of the United Kingdom and the United States, and authorities in the European Union, including applicable export control
regulations, economic sanctions on countries and persons, anti-money laundering laws, customs requirements and currency exchange
regulations, collectively referred to as the Trade Control laws.

However, there is no assurance that we will be completely effective in ensuring our compliance with all applicable anti-corruption
laws, including the Bribery Act, the FCPA or other legal requirements, including Trade Control laws. If we are not in compliance with the
Bribery Act, the FCPA and other anti-corruption laws or Trade Control laws, we may be subject to criminal and civil penalties,
disgorgement and other sanctions and remedial measures, and legal expenses, which could have an adverse impact on our business,
financial condition, results of operations and liquidity. Likewise, any investigation of any potential violations of the Bribery Act, the FCPA,
other anti-corruption laws or Trade Control laws by United Kingdom, United States or other authorities could also have an adverse impact
on our reputation, our business, results of operations and financial condition.

If we are found in violation of federal or state “fraud and abuse” or other health care laws, we may be required to pay a penalty and/or
be suspended from participation in federal or state health care programs, which may adversely affect our business, financial condition
and results of operations.

If we obtain marketing approval for our products in the United States, if at all, we will be subject to various federal and state

health care “fraud and abuse” and other health care laws. Healthcare providers, physicians and third-party payors play a primary role in the
recommendation and use of pharmaceutical products that are granted marketing approval. Accordingly, arrangements with third-party
payors, existing or potential customers and referral sources are subject to broadly applicable fraud and abuse and other healthcare laws and
regulations, and these laws and regulations may constrain the business or financial arrangements and relationships through which
manufacturers market, sell and distribute the products for which they obtain marketing approval.

Such restrictions under applicable federal and state healthcare laws and regulations include the following:

●

●

●

●

the Anti-Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, receiving,
offering or paying remuneration, directly or indirectly, in cash or kind, in exchange for, or to induce, either the referral of an
individual for, or the purchase, order or recommendation of, any good or service for which payment may be made under federal
healthcare programs such as the Medicare and Medicaid programs. This statute has been interpreted to apply to arrangements
between pharmaceutical manufacturers, on the one hand, and prescribers, purchasers and formulary managers on the other.
Cases have been brought under false claims laws alleging that off-label promotion of pharmaceutical products or the provision
of kickbacks has resulted in the submission of false claims to governmental health care programs. The Patient Protection and
Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, collectively, the Healthcare Reform
Act, amended the intent requirement of the Anti-Kickback Statute. A person or entity no longer needs to have actual knowledge
of this statute or specific intent to violate it. Under federal government regulations, some arrangements, known as safe harbors,
are deemed not to violate the Anti-Kickback Statute and analogous state law requirements;

the False Claims Act, or FCA, which prohibits, among other things, individuals or entities from knowingly presenting, or
causing to be presented, claims for payment from Medicare, Medicaid or other third-party payors that are false or fraudulent.
Violations under the Anti-Kickback Statute and certain marketing practices, including off-label promotion, also may implicate
the FCA. In addition, private individuals have the ability to bring actions on behalf of the government under the FCA and under
the false claims laws of several states;

federal criminal laws that prohibit executing a scheme to defraud any healthcare benefit program or making false statements
relating to healthcare matters;

the Physician Payment Sunshine Act, which requires certain manufacturers of drugs, devices, biologics and medical supplies to
report annually to the Centers for Medicare & Medicaid Services, or CMS, information

50

Table of Contents

related to payments and other transfers of value to physicians, other healthcare providers and teaching hospitals, and ownership
and investment interests held by physicians and other healthcare providers and their immediate family members. The CMS
publishes the reported data in a searchable form on an annual basis;

●

The Health Insurance Portability and Accountability Act of 1996 (HIPAA) imposes criminal and civil liability for executing a
scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters;

● HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, which governs the conduct

of certain electronic healthcare transactions and protects the security and privacy of protected health information; and

●

state and foreign law equivalents of each of the above federal laws, such as anti-kickback and false claims laws which may
apply to: items or services reimbursed by any third-party payor, including commercial insurers; state laws that require
pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant
compliance guidance issued by the federal government or otherwise restrict payments that may be made to healthcare providers
and other potential referral sources; state laws that require drug manufacturers to report information related to payments and
other transfers of value to physicians and other healthcare providers or marketing expenditures; and state laws governing the
privacy and security of health information in certain circumstances, many of which differ from each other in significant ways
and may not have the same effect, thus complicating compliance efforts. California and a few other states have passed laws that
require pharmaceutical companies to comply with the April 2003 Office of Inspector General Compliance Program Guidance
for Pharmaceutical Manufacturers and/or the Pharmaceutical Research and Manufacturers of America Code on Interactions
with Healthcare Professionals. In addition, several states impose other marketing restrictions or require pharmaceutical
companies to make marketing or price disclosures to the state. There are ambiguities as to what is required to comply with these
state requirements and if we fail to comply with an applicable state law requirement, we could be subject to penalties.

Neither the government nor the courts have provided definitive guidance on the application of fraud and abuse laws to our
business. Law enforcement authorities are increasingly focused on enforcing these laws. Although we seek to structure our business
arrangements in compliance with all applicable requirements, these laws are broadly written, and it is often difficult to determine precisely
how the law will be applied in specific circumstances. Accordingly, it is possible that, once we begin marketing our product(s) some of our
practices may be challenged under these laws. While we intend to structure our business arrangements to comply with these laws, it is
possible that the government could allege violations of, or convict us of violating, these laws. Violation of any of the laws described above
or any other governmental laws and regulations may result in penalties, including civil and criminal penalties, damages, fines, the
curtailment or restructuring of operations, the exclusion from participation in federal and state healthcare programs and imprisonment.
Furthermore, efforts to ensure that business activities and business arrangements comply with applicable healthcare laws and regulations
can be costly for manufacturers of branded prescription products. Additionally, if we are found in violation of one or more of these laws our
business, results of operations and financial condition may be adversely affected.

Our current cash projections include reliance on the ability to obtain certain tax credits and the operation of certain tax regimes within
the United Kingdom. Should these cease to be available, this could impact our ongoing requirement for investment and the timeframes
within which additional investment is required.

As a company that carries out extensive research and development activities, we benefit from the U.K. research and development

tax credit regime for small and medium sized companies, whereby our principal research subsidiary company, Adaptimmune Limited, is
able to surrender the trading losses that arise from its research and development activities for a payable tax credit of up to approximately
33.4% of eligible research and development expenditures. Qualifying expenditures largely comprise employment costs for research staff,
consumables and certain internal overhead costs incurred as part of research projects. Subcontracted research expenditures are eligible for a
cash rebate of

51

Table of Contents

up to approximately 21.7%. The majority of our pipeline research, clinical trials management and manufacturing development activities, all
of which are being carried out by Adaptimmune Limited, are eligible for inclusion within these tax credit cash rebate claims.

We may not be able to continue to claim research and development tax credits (R&D tax credits) in the future as we increase our
personnel and expand our business because we may no longer qualify as an SME (small or medium-sized enterprise). In order to qualify as
an SME for R&D tax credits, we must continue to be a company with fewer than 500 employees and also have either an annual turnover
not exceeding €100 million or a balance sheet not exceeding €86 million.

We may also benefit in the future from the United Kingdom’s “patent box” regime, which would allow certain profits attributable

to revenues from patented products to be taxed at a rate of 10%. As we have many different patents covering our products, future upfront
fees, milestone fees, product revenues, and royalties could be taxed at this favorably low tax rate. When taken in combination with the
enhanced relief available on our research and development expenditures, we expect a long-term lower rate of corporation tax to apply to us.
If, however, there are unexpected adverse changes to the United Kingdom research and development tax credit regime or the “patent box”
regime, or we are unable to qualify for such advantageous tax legislation, our business, results of operations and financial condition may be
adversely affected.

Risks Related to the Commercialization of Our SPEAR T-cells

The market opportunities for cell therapies may be limited to those patients who have failed prior treatments.

Initial approval of new cancer therapies may be limited to what is referred to as third-line use. Third-line treatment is the third type

of treatment following initial, or first-line, treatment and second-line treatment, which is given when first-line treatment does not work or
ceases working. However, cancer therapies may be used from the point at which cancer is detected in its early stages (first line) onward.
Whenever the first-line therapy fails or the process is unsuccessful, second-line therapy may be administered, such as additional rounds of
chemotherapy, radiation and antibody drugs or a combination of these treatments. If second-line therapies fail, patients are generally given
the opportunity to receive third-line therapies, which tend to be more novel therapies. Our and our collaborators current clinical trials
generally require that patients have received chemotherapy prior to enrollment. Depending upon the outcome of current trials, we or our
collaborators may conduct future clinical trials using cell therapies for first-line therapy, but there can be no guarantee that clinical trials will
be approved or that if approved such trials will lead to regulatory approval. If our cell therapies only receive third-line or second-line
approval, the patient population into which we or our collaborators can supply our cell therapies will be significantly reduced, which may
limit commercial opportunities.

In addition, our patient population may be derived from those who have previously failed checkpoint therapy, which may result in
tumor resistance mechanisms which also impart resistance to our cell therapies and hence may reduce the effectiveness of our cell therapies.

Our estimates of the patient population that may be treated by our cell therapies is based on published information. This
information may not be accurate in relation to our cell therapies and our estimates of potential patient populations could therefore be much
higher or lower than those that are actually available or possible for commercialization. In addition, these estimates are based on
assumptions about the number of eligible patients which have the peptide and HLA type targeted by the applicable cell therapy. Different
patient populations will present different peptides according to their specific HLA type. HLA types vary across the patient population and,
due to this variability, any therapy will initially only be suitable for treatment of patients expressing the particular HLA type presenting the
relevant peptide. Current SPEAR T-cells have been developed for patients who are HLA A2 which will reduce the size of the patient
population that can be treated unless we develop and we or our collaborators receive regulatory approval for cell therapies approved for
additional HLA peptides.

We currently have no marketing and sales organization and 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 cell therapies, we may not be able to
generate product revenue.

As an organization, we have never marketed or supplied commercial pharmaceutical or biologic products or therapies. We do not

currently have a sales force and will need to grow and develop the sales function and associated support network if we are to supply cell
therapies on a commercial basis. As our cell therapies proceed through clinical programs, we intend to develop an in-house marketing
organization and sales force, which will require significant capital expenditures, management resources, and time. We will have to compete
with other pharmaceutical and biotechnology companies to recruit, hire, train, and retain marketing and sales personnel. This process may
result in additional delays in bringing our cell therapies to market or in certain cases require us to enter into alliances with third parties in
order to do so. However, there can be no assurance that we will be able to establish or maintain such collaborative arrangements, or even if
we are able to do so, that they will result in 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 cell therapy sales may be lower than if we had commercialized our cell therapies ourselves. We also face significant competition in
our search for third parties to assist us with the sales and marketing efforts of our cell therapies. Such competition may also result in delay or
inability to supply cell therapies to particular countries or territories in the world which in turn will restrict the revenue that can be obtained
from any cell therapy. Any inability on our part to develop in-house sales and commercial distribution capabilities or to establish and
maintain relationships with third-party collaborators that can successfully commercialize any cell therapy in the United States or elsewhere
will have a materially adverse effect on our business and results of operations.

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

We face an inherent risk of product liability as a result of the clinical testing of our cell therapies and our ongoing manufacture of

cell therapies and will face an even greater risk upon any commercialization. For example, we may be sued if any of our SPEAR T-cells
causes or is perceived to cause injury or is found to be otherwise unsuitable during clinical testing, manufacturing, marketing or sale. Any
such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in
the product, negligence, strict liability or a breach of warranties. Claims could also be asserted under state consumer protection acts. If we
cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit
commercialization of our cell therapies. Even a successful defense would require significant financial and management resources and,
regardless of the merits or eventual outcome, liability claims may result in:

●

●

decreased demand for our cell therapies;

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;

53

Table of Contents

●

●

●

exhaustion of any available insurance and our capital resources;

the inability to commercialize our cell therapies; and

a decline in our share price.

Our inability to obtain sufficient product liability insurance at an acceptable price to protect against potential product liability

claims could also prevent or inhibit the commercialization of our cell therapies. We currently hold £15.0 million in clinical trial insurance
coverage in the aggregate per year, with a per trial limit of £5.0 million. We also hold products and services liability insurance capped at
£3.0 million in the aggregate and public liability insurance capped at £3.0 million per occurrence. These levels may not be adequate to
cover all liabilities that we may incur. We may also need to increase our insurance coverage as we expand the scope of our clinical trials
and commercialize any of our cell therapies. In addition, insurance coverage is increasingly expensive. We may not be able to maintain
insurance coverage at a reasonable cost or in an amount adequate to satisfy any liability that may arise.

Even if we or our collaborators obtain regulatory approval of our cell therapies, they may not gain market acceptance among
physicians, patients, hospitals, cancer treatment centers and others in the medical community.

The use of engineered T-cells and cell therapies more generally 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. Additional
factors will influence whether SPEAR T-cells are accepted in the market, including:

●

●

●

●

●

●

●

●

●

●

●

●

the clinical indications for which our cell therapies are approved;

physicians, hospitals, cancer treatment centers and patients considering the SPEAR T-cells as a safe and effective treatment;

the potential and perceived advantages of our cell therapies over alternative treatments;

the prevalence and severity of any side effects;

product labeling or prescribing information 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 cell therapies as well as competitive products;

the cost of treatment in relation to alternative treatments;

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

the willingness of patients to pay for cell therapies on an out-of-pocket basis in the absence of coverage by third-party payors
and government authorities;

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

the effectiveness of our sales and marketing efforts.

In addition, although we are not utilizing embryonic stem cells or replication competent vectors in our manufacturing process,

adverse publicity due to the ethical and social controversies surrounding the therapeutic use of

54

Table of Contents

such technologies, and reported side effects from any clinical trials using these technologies or the failure of such trials to demonstrate that
these therapies are safe and effective may limit market acceptance of cell therapies including SPEAR T-cells. If our cell therapies are
approved but fail to achieve market acceptance among physicians, patients, hospitals, cancer treatment centers or others in the medical
community, we or our collaborators will not be able to generate significant revenue.

Even if our cell therapies achieve market acceptance, we or our collaborators 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 cell therapies, are more cost effective or
render our cell therapies obsolete.

Coverage and reimbursement may be limited or unavailable in certain market segments for cell therapies, which could make it difficult
for us or our collaborators to sell cell therapies profitably.

Successful sales of cell therapies, if approved, depend on the availability of coverage and adequate reimbursement from third-party

payors. In addition, because cell therapies represent new approaches to the treatment of cancer, we cannot accurately estimate the potential
revenue from cell therapies.

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 governmental healthcare programs, such as
Medicare and Medicaid, and commercial payors is critical to new product acceptance.

Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which
drugs and treatments they will cover and the amount of reimbursement. 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 approval of a cell therapy from a government or other third-party payor is a time-
consuming and costly process which 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 cell therapy, the resulting reimbursement payment rates might not be
adequate for us to achieve or sustain profitability or may require co-payments that patients find unacceptably high. Patients are unlikely to
use cell therapies unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of the cell therapy.

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. As a result, the coverage determination process is
often a time-consuming and costly process that will require us to provide scientific and clinical support for the use of our cell therapies to
each payor separately, with no assurance that coverage and adequate reimbursement will be obtained.

We intend to seek approval to market our cell therapies in both the United States and in selected jurisdictions. If we obtain
approval in one or more foreign jurisdictions for our cell therapies, we will be subject to rules and regulations in those jurisdictions.

55

Table of Contents

In some foreign countries, particularly those in the European Union, 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 cell
therapy. In addition, market acceptance and sales of our cell therapies will depend significantly on the availability of coverage and adequate
reimbursement from third-party payors for the cell therapies and may be affected by existing and future health care reform measures.

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 products profitably. In particular, the recently
enacted U.S. Healthcare Reform Act and its implementing regulations, among other things, revised the methodology by which rebates owed
by manufacturers to the state and federal government for covered outpatient drugs and certain biologics, including our SPEAR T-cells and
other cell therapies, under the Medicaid Drug Rebate Program are calculated, increased the minimum Medicaid rebates owed by most
manufacturers under the Medicaid Drug Rebate Program, extended the Medicaid Drug Rebate program to utilization of prescriptions of
individuals enrolled in Medicaid managed care organizations, subjected manufacturers to new annual fees and taxes for certain branded
prescription drugs, and provided incentives to programs that increase the federal government’s comparative effectiveness research.

Other legislative changes have been proposed and adopted in the United States since the Healthcare Reform Act was enacted. In
August 2011, the Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. A Joint Select
Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through
2021, was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs.

This includes aggregate reductions of Medicare payments to providers up to two percent per fiscal year, which went into effect on
April 1, 2013 and will remain in effect until 2024, unless additional congressional action is taken. In January 2013, President Obama signed
into law the American Taxpayer Relief Act of 2012, or the ATRA, which, among other things, reduced Medicare payments to several
providers, including hospitals, imaging centers and cancer treatment centers, and increased the statute of limitations period for the
government to recover overpayments to providers from three to five years.

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

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

●

●

●

●

●

the demand for cell therapies, if we or our collaborators obtain regulatory approval;

our or our collaborators’ ability to set a price that is fair for our cell therapies;

our or our collaborators’ 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 Reliance Upon Third Parties

We rely on GSK in relation to the performance of programs under the GSK Collaboration and License Agreement and associated
payments.

Performance of the GSK Collaboration and License Agreement and the extent to which further targets are nominated under that
agreement depend on decisions taken by GSK. We have no control over whether GSK will elect to progress additional targets under the
collaboration arrangements and therefore trigger additional payments from GSK under the GSK Collaboration and License Agreement.
GSK also has the ability to influence or control decisions taken in relation to the development of any cell therapies covered by the
agreement.

The GSK Collaboration and License Agreement is effective until all payment obligations expire, including any ongoing royalty

payments due in relation to GSK’s sale of any covered TCR therapeutic candidates. The agreement can also be terminated on a
collaboration program-by-collaboration program basis by GSK for lack of feasibility or inability to meet certain agreed requirements. Both
parties have rights to terminate the agreement for material breach upon 60 days’ written notice or immediately upon insolvency of the other
party. GSK has additional rights to terminate either the agreement or any specific license or collaboration program upon 60 days’ written
notice to us. Additional payments may be due to us as a result of such termination, and where we continue any development of any TCR
therapeutic candidate resulting from a terminated collaboration program, depending on the stage of development, royalties may be payable
to GSK at a mid-single-digit percentage rate of net sales. We also have rights to terminate any license where GSK ceases development or
withdraws any licensed SPEAR T-cells in specified circumstances.

The current development plans or any future development plan agreed upon between GSK and us, including those relating to the

third target program, may be unsuccessful or fail to result in candidate therapies that are feasible for further development or
commercialization. Changes to the development plans or collaboration agreement may impact the timing and extent of milestone payments
made by GSK to us, the nature of the relationship with GSK or the scope of the collaboration with GSK.

There is no guarantee that any payments due on commercialization of products under the GSK Collaboration and License

Agreement will be due or payable by GSK at any time or on the timeframes currently expected. In particular, GSK has now exercised its
option to the NY-ESO SPEAR T-cell program and commercialization of the NY-ESO SPEAR T-cell is now the responsibility of GSK. The
timing for commercialization of the NY-ESO SPEAR T-cell and the route to commercialization will be determined by GSK and we cannot
guarantee that GSK will commercialize the NY-ESO SPEAR T-cell within expected timelines or at all.

Under the GSK Collaboration and License Agreement, we are also prohibited from independently developing or commercializing
therapies directed at the targets subject to outstanding options granted to GSK. All intellectual property rights arising from the performance
of the collaboration and license agreement will be jointly owned apart from intellectual property rights that we solely create. Both GSK and
we have freedom to use jointly owned intellectual property rights.

The relationship with GSK could also result in disputes arising between us and GSK which could result in costly arbitration or

litigation and could impact the ongoing clinical programs or progress of such clinical programs.

We rely on Universal Cells Inc in relation to the performance of collaboration agreements between us and Universal Cells Inc for the
further development of ‘off-the-shelf’ cell therapies.

Development of allogeneic T-cell therapies and our ability to commercialize those allogeneic T-cell therapies may depend heavily

on the performance of Universal Cells under the ongoing collaboration (the "Universal Cells Collaboration") and payments made by
Universal Cells to us in relation to such development.

Under the Universal Cells Collaboration, the parties will agree on up to three targets and will co-develop T-cell therapies directed

to those targets pursuant to an agreed research plan. For each target, Universal Cells will fund co-development up until completion of a
Phase 1 trial for products directed to such target. Upon completion of the Phase 1

57

Table of Contents

trial for a product, we and Universal Cells will elect whether to progress with co-development and co-commercialization of such product, or
to allow the other party to pursue the candidate independently. If we progress with co-development and co-commercialization of a product,
then each party will grant the other party a co-exclusive license to co-develop and co-commercialize such product in the field of T-cell
therapy. If a product is developed solely by one party, then the other party will grant to the continuing party an exclusive license to develop
and commercialize such product in the field of T-cell therapy. Universal Cells will also have the right to select two targets and develop
allogeneic T-cell therapy candidates independently. Universal Cells will have sole rights to develop and commercialize these products,
subject to necessary licenses and the payment of milestones and royalties. The targets to be developed and the resulting therapies to be
developed are currently unknown and, to the extent being co-developed, will need to be agreed between us and Universal Cells.

Under the terms of the agreement, we have received an upfront payment of $50 million and may receive up to an additional
$847.5 million in upfront, development and sales milestones together with up to $7.5 million in research funding per year and tiered
royalties on net sales in the mid-single to mid-teen digits where Universal Cells takes cell therapy candidates forward unilaterally through
development and commercialization. Where we take products forward unilaterally through development and commercialization, we may
have to pay Universal Cells up to $552.5 million in development and sales milestones. In addition, Universal Cells would receive tiered
royalties on net sales in the mid-single to mid-teen digits. To the extent that we and Universal Cells co-develop and co-commercialize any
therapies, we will equally share the costs of such co-development and co-commercialization, with the resulting profits from co-
commercialization also shared equally. There is no guarantee that any research funding, development or sales milestones or product
royalties or any other sums will become due or payable to us at any time or on the time frames currently expected.

Universal Cells has a right to terminate programs under the Universal Cells Collaboration and the agreement in whole or in part for
convenience, on provision of prior written notice. Termination may impact not only our requirement for additional investment or capital but
also the timeframes within which current research and development programs (including clinical programs) can be performed or whether
we can continue to perform those research and development programs at all. Termination may also impact our ability to access and use
certain Universal Cells technology within our own allogeneic platform and products arising from that platform.

Any research or development plan agreed upon between Universal Cells and us may be unsuccessful or fail to result in therapies
that are feasible for further development or commercialization. In addition, milestone payments and research funding may not be paid or
may be varied where any research or development plan is amended or where any research or development plan is terminated prior to
completion. There is no guarantee that any payments due or payable on commercialization of products under the Universal Cells
Collaboration will be due or payable at any time or on the timeframes currently expected. The timing for commercialization of any products
under the Universal Cells Collaboration is currently unknown and will depend on the targets selected and the type of allogeneic T-cell
therapy being developed.

Any research and development plans for allogeneic T-cell therapies under the Universal Cells Collaboration will be subject to

change as a result of risks inherent with the development of any pharmaceutical, biological or gene therapy product. Changes may be
agreed to expand or change the scope of the collaboration or the responsibilities of the parties under the collaboration. Changes to the
development plans or agreement may impact the timing and extent of milestone payments, the amount of research funding received, the
nature of the relationship with Universal Cells or the scope of the collaboration. Delay in performance of responsibilities under any research
or development plan could impact our ability to progress T-cell therapies through research and development, including where Universal
Cells delays the performance of any of its responsibilities. In addition, risks identified during the Universal Cells Collaboration may impact
the development of our own allogeneic therapies outside of the collaboration with Universal Cells.

Universal Cells has the ability to influence or control certain decisions relating to the development of therapies covered by the

Universal Cells Collaboration. This ability could result in delays to the research and development programs covered by the collaboration or
changes to the scope of those programs, including the disease indications relevant to such clinical programs. Under the Universal Cells
Collaboration, restrictions apply to the ability of either

58

Table of Contents

party to independently develop or commercialize certain competing T-cell therapies directed to the same targets as those nominated under
the collaboration. In addition, Universal Cells or its affiliates may have competing internal or commercial interests which could impact our
collaboration or Universal Cells' decision to take any clinical programs forward to the next stage. This could increase the costs required to
further develop or commercialize any therapy or impact on our ability to take any therapy into further development and commercialization.

The relationship with Universal Cells could also result in disputes arising between us and Universal Cells, which could result in
costly arbitration or litigation and could adversely impact the progress of research and development programs or progress of such clinical
programs.

Commercialization of any cell therapies arising from the Universal Cells Collaboration additionally requires a license from iPS

Academia Japan, Inc under certain intellectual property rights owned by IPS Academia Japan, Inc. Although licenses are available, there is
no assurance that the license can be obtained on commercially acceptable terms.

We rely heavily on ThermoFisher and the technology that we license from them.

The ability to use the ThermoFisher Dynabeads® CD3/CD28 technology to isolate, activate and expand T-cells is important to our

ongoing ability to offer SPEAR T-cells. In December 2012, we entered into a series of license and sub-license agreements with Life
Technologies Corporation (now part of ThermoFisher), such agreements having been amended as of November 2019. These agreements
provide us with a field-based non-exclusive license under certain intellectual property rights owned or controlled by ThermoFisher in
relation to the methods of use of the ThermoFisher Dynabeads® CD3/CD28 technology to isolate, activate and expand T-cells and enable
transfection of the T-cells with any TCR genes to manufacture our TCR products and use and sell those TCR products to treat cancer,
infectious disease and/or autoimmune disease. We also have a field-based non-exclusive sub-license under certain other patents which
cover the method of use of the Dynabeads® CD3/CD28 and are controlled by ThermoFisher under a head-license from the University of
Michigan, the United States Navy and the Dana-Farber Cancer Institute.

In June 2016, we entered into a supply agreement with ThermoFisher for the supply of the Dynabeads® CD3/CD28 technology.

The supply agreement runs until December 31, 2025.

ThermoFisher has the right to terminate the above described agreements for material breach or insolvency. On termination of the
license agreements, the supply agreement will also automatically terminate. If ThermoFisher terminates the exclusive license, sub-license
and supply agreements or otherwise refuses or is unable to supply the Dynabeads® product, we will have to seek an alternative source of
the beads or develop an alternative process methodology to enable supply of our cell therapies.

We rely on third parties to manufacture and supply our cell therapies and to develop next generation cell therapies, and we may have to
rely on third parties to produce and process our cell therapies, if approved.

We currently rely partly on outside contract manufacturing organizations (“CMOs”) and other third parties to provide services

related to the manufacture, supply, and processing of our cell therapies. If one or more of these third parties become unable or unwilling to
continue to manufacture our cell therapies (including any raw or intermediate material required for the manufacture of our cell therapies) or
provide their services in the future, we may be forced to find an alternative third-party service provider, which we may not be able to do on
commercially reasonable terms, if at all. Failure to identify a suitable alternative service provider could impact our business, financial
condition or results of operations.

We rely on a limited number of third-party manufacturers and third party service providers for clinical trial product supplies and

services at each stage of the manufacturing process, and as a result we are exposed to the following risks:

● We may be unable to contract with manufacturers on commercially acceptable terms or at all because the number of potential

manufacturers is limited and the FDA, EMA and other comparable foreign regulators must approve any replacement
manufacturer, which would require new testing and compliance inspections.

59

Table of Contents

In addition, a new manufacturer would have to be educated in, and develop substantially equivalent processes for, production
of our cell therapies after receipt of any applicable regulatory approval.

● We may not be able to obtain lentiviral delivery manufacturing slots with third party contract manufacturers within the

timescales we require for supply of lentiviral delivery vector or to obtain agreed dates for such manufacturing slots sufficiently
in advance of the requirement for supply.

● Our third-party manufacturers might be unable to timely formulate and manufacture our cell therapies or produce the quantity

and quality required to meet our clinical trial and commercial needs, if any.

● With any new manufacturing process or new CMO we will need to transfer the manufacturing process or new process to that
CMO. Any delay in the development and transfer of these new processes to the third-party contract supplier or inability of the
third-party contract supplier to replicate or carry out the transferred process at the appropriate level and quality or in a
reproducible fashion will result in delays in our ability to progress clinical programs, further develop our cell therapies and
obtain marketing approval for our cell therapies.

●

Introduction of new raw material or intermediate material manufacturers, such as CMOs for vectors, may require comparability
testing to be carried out to show that the manufacturing process and end material is comparable to the currently used
manufacturing process and/or material. Any inability to show comparability or delay in comparability testing may result in
delays to the supply of the affected materials and as a result delays to clinical trials.

● Contract manufacturers may not be able to execute our manufacturing procedures appropriately, or we may be unable to

transfer our manufacturing processes to contract manufacturers successfully or without additional time and cost. Even where
CMOs fail to manufacture our cell therapies successfully, it may not be possible to achieve re-manufacture quickly or without
expending resources or additional costs.

● Our future contract manufacturers may not perform as agreed, may be acquired by competitors 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 cell therapies. In addition, contract manufacturers may not manufacture within agreed timescales for manufacture and/or
may cancel pre-agreed manufacturing slots, which would result in delays in manufacturing and could require us to find
replacement manufacturers which may not be available to us on favorable terms or at all.

● Manufacturers are subject to ongoing periodic unannounced inspection by the FDA, EMA, and other comparable foreign
regulators and corresponding state agencies to ensure strict compliance with cGMP and other government regulations and
corresponding foreign standards. Although we do not have day-to-day control over third-party manufacturers’ compliance with
these regulations and standards, we are responsible for ensuring compliance with such regulations and standards.

● We may not own, or may have to share, the intellectual property rights to any improvements made by our third-party

manufacturers in the manufacturing process for our cell therapies. Our third party manufacturers may use processes which
infringe or potentially infringe third party intellectual property rights which may result in inability to use such processes going
forward, an increase in the pricing of such processes or a need to change a different process.

● Our third party manufacturers may fail to perform testing and analysis services accurately, in a manner that can be interpreted
or on a timely basis. This could delay or prevent release of our cell therapies and as a result delay clinical trials and patient
treatment.

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

60

Table of Contents

● Our third-party manufacturers may cease to be able to do business with us (whether for insolvency or other reasons, including

takeover, merger or acquisition) at a time when we are unable to source such manufacture elsewhere or at our own
manufacturing facility.

●

Increased costs, unexpected delays, equipment failures, lack of reproducibility, labor shortages, natural disasters, power failures
and numerous other factors which are outside of our control or which may be imposed by our CMOs. For example moving to
commercial phase manufacture usually incurs increased cost and qualification requirements at our CMOs. Such costs may be
prohibitive, or such activities may not be able to be performed within appropriate timelines.

Certain raw materials or precursor materials used in the manufacture and supply of our cell therapies may come from sole source

or limited source suppliers. For example, there are currently a limited number of third party manufacturers within the United States that can
supply us with our lentiviral delivery vector and ThermoFisher is currently the only supplier of the Dynabeads® CD3/CD28 technology.
Should such suppliers be unable to supply or manufacture such raw materials or precursor materials either at all or within required
timescales we may be unable to supply our cell therapies or such supply may be significantly delayed. Inability to obtain such raw materials
or precursor materials may also necessitate changes in the manufacturing process used for supply of our cell therapies. Such changes to the
manufacturing process may need to be developed internally or by a third party and may also require additional regulatory approvals to be
obtained before they can be used for the manufacture and supply of our cell therapies for clinical trials.

In addition, we are focusing manufacture of our cell therapies at a single manufacturing site, namely our Navy Yard facility.

Should the Navy Yard facility be unable to manufacture our cell therapies for any reason, including natural disaster, contamination or for
any regulatory reason, we may be unable to supply cell therapies for our clinical trials unless we can procure manufacture from a third party
manufacturer. There is no assurance that we will be able to procure manufacture from a third party manufacturer or that such manufacture
will be provided within the timescales we require or at an acceptable price. Any change in manufacturer used to produce our cell therapies
requires notification to regulatory authorities which can be time consuming. There is no assurance that regulatory authorities will agree that
any change in manufacturer is acceptable or that the processes used at such manufacturer are comparable to the processes previously used
and additional evidence of comparability may be required.

Our contract manufacturers are also 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 cell therapies by the FDA or the
commercialization of our cell therapies or result in higher costs or deprive us of potential product revenue. We have insurance to cover
certain costs and expenses related to business interruption, which is capped at £3.0 million in the aggregate.

In addition, we will rely on third parties to perform release tests on our cell therapies prior to delivery to patients. If these tests are
not appropriately performed and test data is not reliable, patients could be put at risk of serious harm. For example, if the HLA testing is not
accurate then a patient without the correct HLA-type could be provided with incompatible cell therapies and as a result such patient could
suffer severe side effects or fatality.

We also rely on certain third parties to assist us in the future development of cell therapies including next generation SPEAR T-
cells and manufacture and supply of SPEAR T-cells for patient administration. For example, we have research collaborations with Noile-
Immune and Alpine Immune Sciences in which we are looking to develop next generation cell therapy approaches. As with any research
and development program there is no guarantee of the success of such program or that such program will be carried out by us or our
collaborators within the timescales we currently anticipate.

We have a shared development history with Immunocore, and as a result jointly own certain intellectual property rights which are
required for our ongoing business.

Our TCR technology was originally developed by Avidex, which was subsequently acquired by Medigene in 2006. We were

formed as a new, separate company and licensed our TCR technology for T-cell therapy from Medigene

61

Table of Contents

in July 2008. Immunocore was subsequently formed as a new separate company and acquired the TCR technology for soluble TCRs from
Medigene later in 2008 to develop soluble TCR proteins. Certain of our shareholders also hold shares in Immunocore.

Since January 1, 2018, the Company no longer considers Immunocore to be a related party due to several factors including the
mutual termination of the target collaboration agreement that terminated effective March 1, 2017, our lack of common directors and the
decrease in Immunocore’s share ownership in 2017 to less than 5% of our ordinary shares. However, under the terms of that target
collaboration agreement, we will continue to share a database of identified targets with Immunocore which resulted from the joint target
identification efforts under that agreement.

In addition, many of the patents relating to our underlying core technology in TCR engineering, are co-owned by us and
Immunocore pursuant to a separate assignment and license agreement. Under this agreement, both Immunocore and Adaptimmune utilize
the jointly owned patents and know-how, with Adaptimmune focused on the treatment of patients with engineered SPEAR T-cells and
Immunocore focused on the treatment of patients with soluble TCRs. Under the agreement, each of Immunocore and Adaptimmune grants
the other an exclusive, royalty-free, irrevocable license, with the right to sub-license, to certain jointly owned patents and know-how.
However, there is the potential that Immunocore could develop a soluble TCR product targeting the same cancer target that one of our cell
therapies is targeting, and therefore compete directly with us.

We 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 cell therapies.

We depend upon independent investigators and collaborators, such as universities, medical institutions, CROs and strategic
partners to conduct our preclinical programs and sponsored clinical trials under agreements with us. We expect to have to negotiate budgets
and contracts with CROs and trial sites (either directly or through a third party consultant), which may result in delays to our development
timelines and increased costs. We rely heavily on these third parties over the course of our clinical trials, and we do not have day-to-day
control of their activities. Nevertheless, we are responsible for ensuring that each of our trials is conducted in accordance with applicable
protocols and 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 cGCPs, which are regulations and guidelines enforced by the FDA
and comparable foreign regulatory authorities for cell therapies in clinical development. Regulatory authorities enforce these cGCPs
through periodic inspections of trial sponsors, principal investigators and trial sites. If we or any of these third parties fail to comply with
applicable cGCP regulations and guidelines, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or
comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing authorization
applications. We cannot provide assurances that, upon inspection, such regulatory authorities will determine that any of our clinical trials
comply with the cGCP regulations. In addition, our clinical trials must be conducted with biologic product produced under cGMPs and will
require a large number of subjects. Our failure or any failure by these third parties to comply with these regulations or to support BLA for
approval of any of our cell therapies for the treatment of 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 not and will not be our employees and, except for remedies available to us under
our agreements with such third parties which could be limited, we cannot control whether or not they devote sufficient time and resources to
our ongoing clinical trials and preclinical programs. These third parties may also have relationships with other commercial entities,
including our competitors, for whom they may also be conducting clinical trials or other drug or biologic 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

62

Table of Contents

successfully commercialize our cell therapies. As a result, our financial results and the commercial prospects for our cell therapies would be
harmed, our costs could increase and our ability to generate revenue could be delayed.

Switching or adding third parties to conduct our clinical trials involves substantial cost and requires extensive management time
and focus. In addition, there is a natural transition period when a new third party commences work. As a result, delays may occur, which
can materially impact our ability to meet our timelines for bringing our cell therapies to market, if at all.

We rely on third parties to obtain reagents and raw materials.

The manufacture of our cell therapies requires access to a number of reagents and other raw materials from third parties. Such

third parties may refuse to supply such reagents or other raw materials or alternatively refuse to supply on commercially reasonable terms.
There may also be capacity issues at such third-party suppliers that impact our ability to increase production of our cell therapies.

Some of the materials used in the manufacture and processing of our cell therapies may only be supplied by one or a few vendors,
which means that, should those vendors be unable to supply, for whatever reason, our ability to manufacture cell therapies and progress cell
therapies through clinical trials could be severely impacted and result in additional delays. Such failure to supply could also impact other
supply relationships with other third parties and potentially result in additional payments being made or required in relation to such delays.
In addition, where any raw material or precursor material (including, for example, lentiviral delivery vector, medium or other essential raw
material) is currently supplied by one or a few vendors, replacing such raw material or precursor or finding alternative vendors may not be
possible or may significantly impact on the timescales for manufacture and supply of our cell therapies. Even where alternative materials or
precursors or alternative vendors are identified, such alternative materials, precursors or vendors will need to be properly assessed, validated
and qualified and additional regulatory approvals may also need to be obtained all of which could result in significant delays to the supply
of our cell therapies or an inability to supply our cell therapies within anticipated timescales, if at all.

We rely on third parties for equipment and components necessary to manufacture our cell therapies.

As we further develop our manufacturing process, the manufacture of our cell therapies may require access to specialized or
customized equipment and components from third parties. Such third parties may refuse to supply such equipment and components or
alternatively refuse to supply on commercially reasonable terms. There may also be capacity issues at such third-party suppliers that impact
our ability to manufacture our cell therapies.

Some of the equipment and components used in the manufacture and processing of our cell therapies may only be supplied by one or a few
vendors, which means that, should those vendors be unable to supply, for whatever reason, our ability to manufacture cell therapies and
progress cell therapies through clinical trials could be severely impacted and result in additional delays. While other equipment and
components may be available to perform the same or similar operational steps, such alternative equipment and components may be less
efficient, more costly, and may result in production delays that may detrimentally impact timescales for the manufacture and supply of our
cell therapies. Even where alternative equipment and components are available, such alternatives will need to be properly assessed,
validated and qualified and additional regulatory approvals may also need to be obtained all of which could result in significant delays to
the supply of our cell therapies or an inability to supply cell therapies within anticipated timescales, if at all.

63

Table of Contents

We have formed and may form or seek collaboration agreements or enter into additional licensing arrangements with third parties and
either fail to realize the benefits of such relationships or incur substantial additional costs in performing such relationships.

We have formed and may form or seek further third party alliances, create joint ventures or collaborations or enter into additional

licensing arrangements with third parties that we believe will complement or augment our development, manufacturing and
commercialization efforts with respect to our SPEAR T-cell therapies and any future products. For any of these third party alliances we are
reliant on performance of a third party to achieve the end aims of the alliances. For example, we have a collaboration agreement with
Universal Cells Inc. (“Universal”) under which Universal is required to perform certain collaboration activities. Any delays in the
performance of these activities or any requirement to amend or modify those activities will result in delay to the overall program. 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. There is no guarantee that such third party relationships will
result in any positive improvements to our SPEAR T-cells, cell therapies or associated manufacturing processes or that performance of such
third party relationships will occur in accordance with expected timelines. Such third party alliances may result in us incurring additional
costs or requiring additional resources over and above the costs and resources committed to those alliances. In addition, we face significant
competition in seeking appropriate partners and the negotiation process is time-consuming and complex. Moreover, we may not be
successful in our efforts to establish third party arrangements for our cell therapies which may impact our ability to further develop our cell
therapies or delay the further development of our cell therapies.

Risks Related to Our Intellectual Property

Our cell therapies could be at risk of biosimilar development.

Expedited routes or abbreviated procedures for obtaining regulatory approval for products aiming to target the same cancer peptide

as any SPEAR T-cells or any of our cell therapies may be available to third parties, which we cannot control or prevent. For example, third
parties could develop affinity-enhanced TCRs binding to the same targets and regulatory authorities may accept that they are
interchangeable with our corresponding SPEAR T-cells and, as a result, grant regulatory approval for such competing products. Entry into
the market of such competing products may impact the price of SPEAR T-cells and the extent of commercialization possible in relation to
such SPEAR T-cells.

We may be forced to litigate to enforce or defend our intellectual property rights, and/or the intellectual property rights of our licensors.

We may be forced to litigate to enforce or defend our intellectual property rights against infringement and unauthorized use by

competitors, and to protect our trade secrets. In so doing, we may place our intellectual property at risk of being invalidated, held
unenforceable, narrowed in scope or otherwise limited. Further, an adverse result in any litigation or defense proceedings may increase the
risk of non-issuance of pending applications. In addition, if any licensor fails to enforce or defend its intellectual property rights, this may
adversely affect our ability to develop and commercialize our SPEAR T-cells and to prevent competitors from making, using, and selling
competing products. Any such litigation could be very costly and could distract our management from focusing on operating our business.
The existence and/or outcome of any such litigation could harm our business, results of operations and financial condition.

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

risk that some of our confidential and proprietary 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 ADSs.

64

Table of Contents

We may not be able to protect our proprietary technology in the marketplace or the cost of doing so may be prohibitive or excessive.

Our success will depend, in part, on our ability to obtain patents, protect our trade secrets and operate without infringing on the

proprietary rights of others. We rely upon a combination of patents, trade secret protection (i.e., know-how), and confidentiality agreements
to protect the intellectual property of our cell therapies. The scope and validity of patents in the pharmaceutical field involve complex legal
and scientific questions and can be uncertain. Where appropriate, we seek patent protection for certain aspects of our cell therapies and
technology. Filing, prosecuting and defending patents throughout the world would be prohibitively expensive, so our policy is to patent
technology in jurisdictions with significant commercial opportunities. However, patent protection may not be available for some of the cell
therapies or technology we are developing. If we must spend significant time and money protecting or enforcing our patents, designing
around patents held by others or licensing, potentially for large fees, patents or other proprietary rights held by others, our business results
of operations and financial condition may be harmed. We may not develop additional proprietary products that are patentable.

Many companies have encountered significant problems in protecting and enforcing intellectual property rights in foreign
jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents and
other intellectual property rights, particularly those relating to pharmaceuticals, 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 cost and divert our efforts and attention from other aspects of our business.

In addition, patents have a limited lifespan. In most countries, including the United States, the standard expiration of a patent is

20 years from the effective filing date. Various extensions of patent term may be available in particular countries; however, in all
circumstances the life of a patent, and the protection it affords, has a limited term. If we encounter delays in obtaining regulatory approvals,
the period of time during which we could market a product under patent protection could be reduced. We expect to seek extensions of patent
terms where these are available in any countries where we are prosecuting patents. Such possible extensions include those permitted under
the Drug Price Competition and Patent Term Restoration Act of 1984 in the United States, which permits a patent term extension of up to
five years to cover an FDA-approved product. The actual length of the extension will depend on the amount of patent term lost while the
product was in clinical trials. However, the applicable authorities, including the FDA in the United States, and any equivalent regulatory
authority in other countries, may not agree with our assessment of whether such extensions are available, and may refuse to grant extensions
to our patents, or may grant more limited extensions than we request. If this occurs, our competitors may be able to take advantage of our
investment in development and clinical trials by referencing our clinical and non-clinical data, and then may be able to launch their product
earlier than might otherwise be the case.

Any loss of, or failure to obtain, patent protection could have a material adverse impact on our business. Enforcement of patents

may also be cost prohibitive and we may be unable to prevent competitors from entering the market with products that are similar to or the
same as our cell therapies. This is particularly the case where third parties are using T-cell therapies falling within the scope of our patents
in clinical trials. It may not be possible to enforce our patents against such third parties during the course of those clinical trials.

Further given that our technology relates to the field of genetic engineering, political pressure or ethical decisions may result in a

change to the scope of patent claims for which we may be eligible. Different patent offices throughout the world may adopt different
procedures and guidelines in relation to what is and is not patentable and as a result different protection could be obtained in different areas
of the world which may impact our ability to maximize commercialization of our technology.

We may also incur increased expenses and cost in relation to the filing and prosecution of patent applications where third parties
choose to challenge the scope or oppose the grant of any patent application or, following grant, seek to limit or invalidate any patent. Any
increased prosecution or defense required in relation to such patents and patent applications, whether relating to this third party observation
or any other third party challenge or opposition, entails

65

Table of Contents

increased cost and resource commitment to the business and may result in patents and patent applications being abandoned, invalidated or
narrowed in scope.

We may be unable to adequately prevent disclosure of trade secrets and other proprietary information.

We rely on trade secrets to protect our proprietary know-how and technological advances, especially where we do not believe

patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. We rely, in part, on confidentiality agreements
with our employees, consultants, outside scientific collaborators, sponsored researchers and other advisors to protect our trade secrets and
other proprietary information. These agreements may not effectively prevent disclosure of confidential information and may not provide an
adequate remedy in the event of unauthorized disclosure of confidential information. In addition, others may independently discover our
trade secrets and proprietary information. Costly and time-consuming litigation could be necessary to enforce and determine the scope of
our proprietary rights. Failure to obtain or maintain trade secret protection, or failure to adequately protect our intellectual property, could
enable competitors to develop generic products or use our proprietary information to develop other products that compete with our SPEAR
T-cells or other cell therapies or have additional, material adverse effects upon our business, results of operations and financial condition.

In addition, we provide samples to third parties under material transfer agreements, including to research institutions or other
organizations that we cannot control. There is a risk that such third parties could disclose details of those samples or carry out further
research in relation to provided samples which results in intellectual property rights that block our future freedom to operate, and to which
we may not be able to obtain a license on commercially acceptable terms or at all. In addition, provision of samples and our confidential
information to such parties could facilitate or assist such parties in development of competing products.

If third parties claim that our activities or products infringe upon their intellectual property, our operations could be adversely affected.

There is a substantial amount of litigation, both within and outside the United States, involving patents and other intellectual

property rights in the pharmaceutical industry. We may, from time to time, be notified of claims that we or our third party suppliers are
infringing upon patents, trademarks, copyrights, or other intellectual property rights owned by third parties, and we cannot provide
assurances that other companies will not, in the future, pursue such infringement claims against us or any third-party proprietary
technologies we have licensed. If we or our third party suppliers were found to infringe upon a patent or other intellectual property right, or
if we failed to obtain or renew a license under a patent or other intellectual property right from a third party, or if a third party that we were
licensing technologies from was found to infringe upon a patent or other intellectual property rights of another third party, we may be
required to pay damages, including triple damages if the infringement is found to be willful, suspend the manufacture of certain of our cell
therapies or reengineer or rebrand our cell therapies, if feasible, or we may be unable to enter certain new product markets. Any such claims
could also be expensive and time- consuming to defend and divert management’s attention and resources. Our competitive position could
suffer as a result. In addition, if we have declined to enter into a valid non-disclosure or assignment agreement for any reason, we may not
own an invention or intellectual property rights and may not be adequately protected. Although we have reviewed certain third-party
patents and patent filings that we believe may be relevant to our cell therapies, we have not conducted a full freedom-to-operate search or
analysis for such cell therapies, and we may not be aware of patents or pending or future patent applications that, if issued, would block us
from commercializing our cell therapies. Thus, we cannot guarantee that we can successfully commercialize our cell therapies in a way that
will not infringe any third party’s intellectual property.

Licenses may be required from third parties in relation to any of cell therapies developed or commercialized by us.

We may identify third-party intellectual property rights that are required to enable the further development, commercialization,

manufacture or development of our SPEAR T-cells. Licenses to such intellectual property rights may or may not be available on
commercial terms that are acceptable to us. As a result we may incur additional license fees for such intellectual property rights, or the cost
and expenses to identify an alternative route for commercialization, that does not require the relevant third-party intellectual property rights,
or the cost and diversion of resources required to challenge any such third party intellectual property rights. For example,
commercialization of iPSC derived ‘off-the-

66

Table of Contents

shelf’ cell therapies are likely to require a license from iPS Academia Japan Inc under intellectual property rights covering the generation of
iPSC cell lines.

We may also require licenses under third-party patents covering certain peptide sequences or the use of those peptides. Such
licenses will require payment of sums by us and we cannot guarantee that the terms of such licenses will be available on commercially
acceptable terms or at all, which could limit the peptides which can be used by us and the efficacy of the final affinity- enhanced TCRs that
we are able to offer.

As we change, develop and modify our manufacturing processes we may identify further third-party patents covering those
developments and modifications. We cannot guarantee that we will be able to obtain licenses under these third-party patents or other
intellectual property rights and as a result we may not be able to undertake the developments of modifications that we wish, either at all or
in the timescales we require. This could ultimately impact our ability to deliver commercial T-cell products at the cost required.

The fees associated with such third-party licenses, including any associated up-front fees, milestone payments, and/or on-going

royalty payments may be significant and may not be aligned with the value obtained by us from such licenses. For example, we may not be
successful in commercializing any next-generation SPEAR T-cell products which incorporate licensed technology to offset any up-front or
milestone payments we may have incurred in the development of such next-generation SPEAR T-cell products.

Further or other third-party patents and patent applications may be identified from time to time that require prospective action by

us to prevent the grant of broad claims. Such prospective action requires time and expense and also impacts on the resources generally
available to us.

Where we license certain technology from a third party, the prosecution, maintenance and defense of the patent rights licensed from
such third party may be controlled by the third party which may impact the scope of patent protection which will be obtained or
enforced.

Where we license patent rights or technology from a third-party, control of such third party patent rights may vest in the licensor,

particularly where the license is non-exclusive or field restricted. This may mean that we are not able to control or affect the scope of the
claims of any relevant third-party patent or have control over any enforcement of such a patent. Where a licensor brings an enforcement
action, this could negatively impact our business or result in additional restrictions being imposed on the license we have and the scope of
such license or result in invalidation or limitation of the scope of the licensed patent. In addition, should we wish to enforce the relevant
patent rights against a third person, we may be reliant on consent from the relevant licensor or the cooperation of the licensor. The licensor
may refuse to bring such action and leave us unable to restrict competitor entry into the market.

Issued patents protecting our SPEAR T-cells or other cell therapies could be found invalid or unenforceable if challenged in court or at
the USPTO.

If we or one of our collaborators initiate legal proceedings against a third party to enforce a patent protecting one of our SPEAR

T-cells or cell therapies, the defendant could counterclaim that the patent protecting our cell therapy, 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 re-examination, post grant review, and equivalent proceedings in foreign jurisdictions (e.g., opposition proceedings).
Such proceedings could result in revocation or amendment to our patents in such a way that they no longer cover our cell therapies. The
outcome following legal assertions of invalidity and unenforceability is unpredictable. With respect to the validity question, for example,
we cannot be certain that there is no invalidating prior art, of which we, our patent counsel and the patent examiner were unaware during
prosecution. If a defendant were to prevail on a legal assertion of invalidity and/or unenforceability, we would lose at least part, and perhaps
all, of the patent protection for our cell therapies. Such a loss of patent protection could have a material adverse impact our business,
financial condition and results of operations.

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

As is the case with other biopharmaceutical companies, our success is heavily dependent on intellectual property, particularly

patents. Obtaining and enforcing patents in the biopharmaceutical industry involve both technological and legal complexity, and is therefore
costly, time-consuming and inherently uncertain. In addition, the United States has recently enacted and is currently implementing wide-
ranging patent reform legislation. Recent U.S. Supreme Court rulings have narrowed the scope of patent protection available in certain
circumstances and weakened the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability
to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained.
Depending on decisions by the U.S. Congress, the federal courts, and the USPTO, the laws and regulations governing patents could change
in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents that we might
obtain in the future. For example, in Assoc. for Molecular Pathology v. Myriad Genetics, Inc., the U.S. Supreme Court held that certain
claims to DNA molecules are not patentable. While we do not believe that any of the patents owned or licensed by us will be found invalid
based on this decision, we cannot predict how future decisions by the courts, the U.S. Congress or the USPTO may impact the value of our
patents.

Our ability to protect our intellectual property rights in territories outside of the United States may vary and thus affect our ability to
obtain revenue from our cell therapies.

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

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

Risks Related to Employee Matters and Managing Growth

We depend upon our key personnel and our ability to attract and retain employees.

We are heavily dependent on the ongoing employment and involvement of certain key employees in particular, Adrian Rawcliffe,

our Chief Executive Officer; Dr. Helen Tayton-Martin, our Chief Business Officer; William Bertrand, our Chief Operating Officer; John
Lunger, our Chief Patient Supply Officer and Dr. Elliot Norry, our Senior Vice President and Chief Medical Officer. Michael Garone is
serving as our Interim Chief Financial Officer through March 31, 2020. Gavin Wood has been appointed to serve as our Chief Financial
Officer effective from April 1, 2020. We do not hold key-man insurance for our senior managers.

68

Table of Contents

Our business is dependent on our ability to recruit experienced and suitably trained employees or consultants, and to retain such

employees on a long-term basis. To induce employees to remain at our company, in addition to salary and cash incentives, we have
provided share options that vest over time, with higher awards of share options being made to senior employees. The value to employees of
share options that vest over time may be significantly affected by movements in our share 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 all of our employees in the United Kingdom, these employment agreements provide for a mutual
nine months’ notice period in the case of Dr. Tayton-Martin and Mr. Wood; mutual three months’ or two months’ notice periods in the case
of senior managers and mutual one-month notice periods for all other employees. In the United States, the employment agreements provide
for at-will employment except that, under their employment agreements, Mr. Rawcliffe, Mr. Bertrand and Mr. Lunger must provide
60 days’ written notice and our senior vice-presidents, including Dr. Norry, must provide 30 days’ written notice. This means that any of
our employees in the United States, except for Mr. Rawcliffe, Mr. Bertrand, Mr. Lunger and our senior vice-presidents, could leave our
employment at any time, with or without notice. 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. The uncertainty
around the impact of the U.K.s exit from the European Union (“Brexit”) may make it more difficult to retain and to continue to attract
employees into our U.K. facilities.

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

As of December 31, 2019, we had 400 employees. As our development and commercialization plans and strategies develop, we
must add a significant number of additional managerial, operational, sales, marketing, financial, and other personnel. Future growth will
impose 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 SPEAR T-cells,

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 SPEAR T-cells will depend, in part, on our ability to retain

employees and effectively manage any future growth. Our management may also have to divert a disproportionate amount of its attention
away from day-to-day activities in order to devote a substantial amount of time to managing growth activities and the resourcing of
replacement employees in the event employees leave. For example, competition for employees able to perform manufacturing activities in
the cell therapy area is increasing as more companies develop their own manufacturing capabilities. Should we be unable to retain key
manufacturing employees, this could impact on our ability to manufacture cell therapies for our clinical trials or result in delays to patient
treatment.

We also rely on third parties to provide certain of our manufacturing and quality capabilities. See “Risks Related to Our Reliance

Upon Third Parties.”

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 cell therapies and,
accordingly, may not achieve our research, development, and commercialization goals.

Table of Contents

We have our own manufacturing facility which may result in increased costs being incurred by the company

During 2017, we opened a manufacturing facility for our SPEAR T-cell products within our Navy Yard facility in Philadelphia,

Pennsylvania and have started manufacturing SPEAR T-cells for use in our clinical trials. We cannot guarantee that the regulatory
authorities, in particular the FDA, will continue to approve our ability to manufacture SPEAR T-cells or other cell therapies at the Navy
Yard facility.

Our ability to successfully manufacture our own cell therapies at the Navy Yard facility within a reasonable period of time and

within currently projected costs is dependent on a number of factors including:

●

●

●

●

●

●

●

our ability to recruit the required employees at a suitable level and experience and within required timescales and to maintain
employment of such required employees;

our ability to obtain regulatory approval for the facility and for the manufacture of cell therapies at the facility and to satisfy
regulatory authorities on an ongoing basis;

our ability to manufacture cell therapies reliably and reproducibly and to timescales sufficient to support required patient
administration;

our ability to manufacture cell therapies in compliance with the applicable regulatory requirements, including requirements
applicable in both the United States and European Union;

our ability to develop internal quality controls and processes sufficient to enable manufacture and supply of cell therapies at our
Navy Yard facility;

our ability to establish comparability with currently used manufacturing processes and for such comparability data to be
accepted by the appropriate regulatory authorities; and

our ability to be able to fund the ongoing development including equipment requirements necessary for successful manufacture
of cell therapies at our facility.

Any delay or failure in manufacture at our facility could result in delays to the supply of cell therapies for our clinical programs.

Should any of our third party manufacturers also cease to be able to supply cell therapies at a time where our own manufacturing facility is
unable to produce cell therapies for use in our clinical programs or is unable to produce cell therapies at the required level, then we will be
unable to support such clinical programs until alternative manufacturing capability is secured.

We are in the process of increasing the number of manufacturing slots available at our Navy Yard facility. The cost of developing,
out-fitting and operating a larger manufacturing facility may also be greater than currently anticipated and we may require additional capital
for the completion of the upscaling of the manufacturing facility which may result in the need for us to raise additional funds earlier than
expected.

We cannot guarantee that we will be successful in manufacturing cell therapies at all or in a manner that complies with regulatory

requirements. For example, there is a risk that any cell therapies we manufacture are contaminated or are otherwise incorrectly
manufactured resulting in injury or death to any patient receiving those cell therapies. Such failure could result in a halt being placed on
manufacture at our Navy Yard facility. We may also face difficulties in properly tracking and administering our cell therapies to patients,
again potentially resulting in injury or death to any patient receiving those cell therapies.

We may also be unable to support use of our own manufacturing facility together with third party suppliers and become the sole
supply for our cell therapies. Any inability to supply SPEAR T-cells at the required levels and to the required specifications, will result in
delays to clinical trials and may result in holds being applied to such clinical trials.

We expect to face intense competition, which may be from companies with greater resources and experience than we have.

Immunotherapy is an active area of research and a number of immune-related products have been identified in recent years that

are alleged to modulate the immune system. Many of these products utilize dendritic cells, a form of immune cell that presents cancer
target peptides to T cells and that can in turn result in T-cell activation. More recently, bi-specific antibodies and checkpoint inhibitors (for
instance PD-1/PD-L1 antibodies) have been identified as having utility in the treatment of cancer. Bi-specific antibodies commonly target
both the cancer peptide and the TCR, thus bringing both cancer cells and T cells into close proximity to maximize the chance of TCR
binding and hence an immune response to the cancer cells. Checkpoint inhibitors on the other hand work by targeting receptors that inhibit
T-cell effectiveness and proliferation and essentially activate T cells. Other immunotherapies that are being actively investigated include:
antibody-drug complexes, TCR-mimic antibodies, oncolytic viruses, cancer vaccines. A variety of cell-based autologous and allogeneic
(“off-the-shelf”) approaches are also being researched and developed, including but not limited to: CAR-T cell, TCR T-cell, GammaDelta
T-cell, CAR-NK cell, NK cell, NKT cell and CTL.

● CAR-T in hematological malignancies: Engineered T-cell therapeutics have been identified using antibody recognition systems
engineered into T cells, so-called CAR-T cells. A number of targets in hematological malignancies have been well characterized
including, but not limited to: BCMA, CD4, CD5, CD19, CD22, CD20, CD33, CD38, CD70, CS1 and CD123. Two CD-19 directed
CAR-T cell products have been approved by the U.S. Food and Drug Administration (“FDA”) Kymriah™ (tisagenlecleucel) and
Yescarta™ (axicabtagene ciloleucel) as well as by the European Medicines Agency (EMA) in the European Union. More recently,
Kymriah™ has been approved by the MHLW in Japan. A number of companies and academic institutions are developing CAR-T
cell products including but not limited to Allogene Therapeutics, Arcellx, Atara Bio, Autolus, Baylor College of Medicine, bluebird
bio, CASI Pharmaceuticals, Celyad, Celgene (now part of Bristol-Myers Squibb), Cellectis, CRISPR Therapeutics, Fate
Therapeutics, Janssen (JNJ with Nanjing Legend), Juno Therapeutics (a Bristol-Myers Squibb company), Kite Pharma (Gilead),
Linea Rx, Mustang Bio, Novartis, Precigen, Refuge Biotechnologies Inc, Servier, Sorrento Therapeutics, Xenetic Biosciences,
Xyphos (a wholly owned subsidiary of Astellas) and Ziopharm Oncology.

● CAR-T in solid tumors: In addition to hematological malignancies, there are a growing number of pharmaceutical, biotechnology,
and academic institutions researching and developing autologous and allogeneic CAR-T therapies in the solid tumor setting. These
CAR-T cell therapies are at a variety of stages of preclinical and clinical development, as well as directed towards a broad target
spectrum, including but not limited to: DLL3, EGFR, GD2, HER-2, IL13rα2, Lewis Y, L1-CAM, Mesothelin, MUC16, PSCA,
PSMA and ROR1. Competitors include but are not limited to: Allogene Therapeutics, Amgen, Atara Bio, Aurora Biopharma,
Baylor College of Medicine, Cell Medica, Bellicum, BioNTech, Carisma Therapeutics (formerly CARMA Therapeutics), Carsgen,
Celgene (now part of Bristol-Myers Squibb; with Obsidian Therapeutics) Cellectis Therapeutics, Celyad, CRISPR Therapeutics,
Endocyte (a Novartis Company), Fate Therapeutics, Formula Therapeutics, Fred Hutchinson Cancer Research Center, Helix
BioPharma, Juno Therapeutics (a Bristol-Myers Squibb company), Lyell Immunopharma (with GSK), MaxCyte, Memorial Sloan
Kettering Cancer Center, Minerva Biotechnologies, Mustang bio, OncoSec Immunotherapies, Oncternal Therapeutics, Poseida
Therapeutics, Precigen, Senti Biosciences, Sorrento Therapeutics, Symvivo, Targazyme, Tmunity, Xyphos (a wholly owned
subsidiary of Astellas).

● CARs & TCR-mimics targeting peptide-HLA complexes: Most CAR-T therapies in development are directed towards suitable
antigen targets. Another area of development is the creation of CAR-T that selectively binds to the peptide-HLA (pHLA) complex
(the natural binding site for endogenous TCR). Furthermore, competitors are also looking at pHLA antibodies or TCR mimic
antibodies that can either be engineered in T-cells or developed as standalone antibody therapies in cancer indications (both
hematologic malignancies and solid tumors). Targets of such pHLA CAR-T or TCR mimic antibodies include: AFP, CD19, BCMA,
NY-ESO-1, p53 and WT1. A number of pharmaceutical, biotechnology, and academic institutions are researching and developing
CARs & TCRmimics targeting the peptide-HLA complex, including but not limited to: Adicet Bio / Regeneron, Altor Bioscience,
Cancer Research Technology/CRUK, Eureka Therapeutics, Gritstone Oncology, MorphoSys, Xencor and Ziopharm Oncology.
● TCR T-cells: TCR T-cells are being developed by competitors that are directed towards a multitude of targets including: AFP,

CD20, HPV-16 E6/E7, KRAS, MAGE-A1, MAGE-A3, MAGE A3/A6, MART1, NRAS, NY-

ESO-1, p53, PRAME, TGFβRII frameshift antigen WT1, as well as personalized neoantigens. Juno Therapeutics (a Bristol-Myers
Squibb company) has developed an engineered TCR therapeutic candidate where the end TCR is purported to have enhanced
affinity through stem-cell selection. Juno’s candidate JTCR016 (WT1-specific TCR), in collaboration with Fred Hutchinson Cancer
Research Center and the National Cancer Institute (NCI), is currently undergoing a Phase 1/2 trial in NSCLC and mesothelioma
setting as well as a separate Phase 1/2 in AML. Medigene AG has reported development of a PRAME TCR therapeutic candidate
(MDG1011), which has begun a Phase 1/2 clinical investigation in AML, MM and myelodysplastic syndromes. In addition to Juno
there is a growing number of TCR companies that are adopting approaches to TCR affinity enhancement, for example Axis
Therapeutics, Takara, Takara Bio, Fred Hutchinson Cancer Centre and Immatics. In addition other TCR-focused competitors
include, but are not limited to: 3T, Adaptive Biotechnologies (with Genentech), AgenTus, Atreca, Baylor College, Bellicum,
BioNTech (with Eli Lilly), bluebird bio, BlueSphere bio, Captain T cell, Celgene (now part of Bristol-Myers Squibb; with
Immatics), Cellular Biomedicine Group Inc, Cell Medica Ltd, Cytovant Sciences, Ervaxx, GigaMune, GSK, HighPass Bio (an
Elevate bio company), Immunocellular Therapeutics, Immunocore, Intellia Therapeutics, Inc. (with Ospedale San Raffaele), Juno
Therapeutics (a Bristol-Myers Squibb company), Kiromic, Kite Pharma (Gilead), Lion TCR LTD, MD Anderson Cancer Center,
MediGene AG, NCI, Neon Therapeutics, PACT Pharma, Parker Institute, Refuge Biotechnologies Inc., Roswell Park Cancer
Institute, Scancell (with BioNTech), Tactiva Therapeutics, Takara Bio Inc, Takeda (T-CIRA), TCR Cure, T-Cure, TCR x
immunotherapies, T-Knife, Tmunity, TScan Therapeutics, University of Leiden, Zelluna (with Oslo University Hospital) and
Ziopharm Oncology.

There are a number of different approaches being developed for allogeneic or “off-the-shelf” immunotherapy products including

stem-cell derived products, HLA-matched products, healthy-donor derived products and use of cells with no or limited HLA type (for
example GammaDelta T-cell, or NK cells). Competitors include Allogene Therapeutics (with Notch Therapeutics), Century Therapeutics
(with FujiFilm Cellular Dynamics), City of Hope (with Mustang Bio), Editas, Fate Therapeutics, Takeda (in collaboration with CiRA),
Thyas, Editas, UCLA and T-CiRA.

In addition to adoptive cell therapy approaches aforementioned, our competitors are also investigating other cell-based
approaches, including the potential of GammaDelta T-cell, CAR-Macrophages, CAR-NK cell, NK cell, NKT cell, CTLs, TILs, Marrow-
infiltrating lymphocytes (MILs), Multi-tumor-associated antigen (TAA)-specific T-cells and virus-specific T-cells either preclinically or in
a clinical setting (both hematologic malignancies and solid tumors). In this space there are a number of potential competitors, including, but
not limited to: Achilles Therapeutics, Adicet Bio, Arsenal bio, Atara Bio, Aurora BioPharma, Cell Medica, Cellular Biomedicine Group
Inc, CytomX, Celgene (now part of Bristol-Myers Squibb), Fate Therapeutics, Fortress Biotech, Gadeta (with Kite Pharma), Gamma Delta
Therapeutics (with Takeda), Gamida cell, Genocea, Glycostem Therapeutics, iCell Gene Therapeutics, Immatics, Iovance Biotherapeutics
(formerly Lion Bio), KSQ Therapeutics, MD Anderson Cancer Center, Multimmune, NantKwest, NexImmune, Nkarta, Sorrento
Therapeutics, Marker Therapeutics, Tessa Therapeutics, TC Biopharm (with bluebird bio), Torque Therapeutics, Unum Therapeutics,
WindMIL Therapeutics and Ziopharm Oncology. Although Immunocore is focused on soluble TCRs rather than engineered cell therapies,
we could also face competition from Immunocore if it develops or acquires products directed at the same targets or indications as our TCR
therapeutic product candidates. Moreover, many of our employees have come from a shared background within Immunocore and there is
an awareness within Immunocore of certain of our confidential information on the technology platform controlled through confidentiality
agreements. This knowledge could be used by Immunocore to facilitate its own developments or to target competitive products against our
products placing it in a preferable position as compared to third party competitors.

The United Kingdom’s withdrawal from the European Union could lead to increased market volatility, which could adversely impact the
market price of our ADSs and make it more difficult for us to do business in Europe or have other adverse effects on our business.

The United Kingdom formally exited the European Union, commonly referred to as Brexit, on January 31, 2020. Under the terms
of its departure, the United Kingdom will enter a transition period during which it will continue to follow all European Union rules and the
trading relationship will remain the same. The transition period is scheduled to end on December 31, 2020. The long-term effects of Brexit
will depend on the agreements and arrangements the United Kingdom negotiates with the European Union including whether and to what
extent it will retain access to the European Union markets following the transition period. There will be a period of considerable uncertainty
particularly in relation

72

Table of Contents

to United Kingdom financial and banking markets as well as on the regulatory process in Europe as these negotiations continue to unfold.
As a result of this uncertainty, financial markets could experience volatility which could adversely affect the market price of our ADSs.
Depending on the final terms of the agreements and arrangements negotiated with the European Union, we may also face new regulatory
costs and challenges that could have a material adverse effect on our operations, including the potential for a delay in our clinical progress
and approvals in Europe. In particular, we could be subject to increased regulatory requirements in relation to the procurement, supply and
transport of our end products, apheresis product used to manufacture end product and samples taken during clinical trials. There may be
increased requirements for additional resources, procedures or licenses to facilitate the performance of our clinical trial protocols for
example in relation to the release of our cell therapies, which are manufactured outside of the European Union, for use within the European
Union. Given the uncertainty created by Brexit, we may find it more difficult to recruit and retain staff from the European Union and
certain staff may choose to seek employment in other European Union countries rather than remain in the United Kingdom.

As a result of the foregoing developments, and in the absence of any clear indication that any agreement or arrangement with the
European Union will contain a contrary requirement, we have already appointed our CROs to act as European Union legal representatives
to act on our behalf in accordance with Article 19 of the European Union Clinical Trials Directive (Directive 2001/20/EC). We have also
appointed quality representatives within the European Union to ensure our therapies can be released for use in the European Union in our
clinical trials. Depending on the final terms of any agreements of arrangements there may be an impact on movement of goods between the
European Union and the United Kingdom and additional requirements may apply prior to use of our products within the European Union.

Depending on the terms of Brexit, the United Kingdom could lose the benefits of global trade agreements negotiated by the

European Union on behalf of its members, which may result in increased trade barriers which could make our doing business worldwide
more difficult. In addition, currency exchange rates in the pound sterling and the euro with respect to each other and the U.S. dollar have
already been adversely affected by Brexit. Should this foreign exchange volatility continue it could cause volatility in our financial results.

Failure of our information technology systems could significantly disrupt the operation of our business.

Our ability to execute our business plan and to comply with regulators’ requirements with respect to data control and data
integrity, depends, in part, on the continued and uninterrupted performance of our information technology systems and similar systems used
by third-party providers that we rely on. These systems are vulnerable to damage from a variety of sources, including telecommunications
or network failures, malicious human acts and natural disasters. Moreover, despite network security and back-up measures, some of our
servers are potentially vulnerable to physical or electronic break-ins, computer viruses and similar disruptive problems. Despite the
precautionary measures we have taken to prevent unanticipated problems that could affect our information systems, sustained or repeated
system failures or problems arising during the upgrade of any of our information systems that interrupt our ability to generate and maintain
data, and in particular to operate our proprietary technology platform, could adversely affect our ability to operate our business. In addition,
where disruption to such systems occurs at third-party providers, we may have limited ability to find alternative providers in any required
timeframes or at all, and such disruption could significantly affect our ability to proceed with clinical or analytical or development
programs.

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

Our operations and those of our third party suppliers and collaborators could be subject to earthquakes, power shortages,
telecommunications failures, water shortages, floods, hurricanes or other extreme weather conditions, medical epidemics, labor disputes or
other business interruptions. While the company has business interruption insurance policies in place, any interruption could seriously harm
our ability to timely proceed with any clinical programs or to supply SPEAR T-cells on a commercial basis or for use in clinical programs.

Table of Contents

We are exposed to risks related to currency exchange rates.

We conduct a significant portion of our operations within the United Kingdom in both U.S. dollars and pounds sterling and our
arrangements with GSK are denominated in pounds sterling. Changes in currency exchange rates have had and could have a significant
effect on our operating results. Exchange rate fluctuations between the U.S. dollar and local currencies create risk in several ways,
including the following: weakening of the pound sterling may increase the cost of overseas research and development expenses and other
costs outside the United Kingdom; strengthening of the U.S. dollar may decrease the value of any future revenues denominated in other
currencies. Effects of exchange rates on transactions and cash deposits held in a currency other than the functional currency of a subsidiary
can distort our financial results; and commercial pricing and profit margins are affected by currency fluctuations.

We may be classified as a passive foreign investment company in any taxable year and U.S. holders of our ADSs could be subject to
adverse U.S. federal income tax consequences.

The rules governing passive foreign investment companies, or PFICs, can have adverse effects for U.S. federal income tax

purposes. The tests for determining PFIC status for a taxable year depend upon the relative values of certain categories of assets and the
relative amounts of certain kinds of income. The determination of whether we are a PFIC depends on the particular facts and circumstances
(such as the valuation of our assets, including goodwill and other intangible assets) and may also be affected by the application of the PFIC
rules, which are subject to differing interpretations. In addition, it is not entirely clear how to apply the income test to a company like us,
which for any particular taxable year may have gross income that is either entirely passive or that significantly exceeds any active gross
income, but the overall losses of which from research and development activities exceed the overall amount of its gross income for that
year. Based on our estimated gross income, the average value of our assets, including goodwill and the nature of our active business,
although not free from doubt, we do not believe that the Company was classified as a PFIC for U.S. federal income tax purposes for the U.S.
taxable year ended December 31, 2019. There can be no assurance, however, that we will not be considered to be a PFIC for this taxable
year or any particular year in the future because PFIC status is factual in nature, depends upon factors not wholly within our control,
generally cannot be determined until the close of the taxable year in question and is determined annually.

If we are a PFIC, U.S. holders of our ADSs would be subject to adverse U.S. federal income tax consequences, such as

ineligibility for any preferred tax rates on capital gains or on actual or deemed dividends, interest charges on certain taxes treated as
deferred, and additional reporting requirements under U.S. federal income tax laws and regulations. A U.S. holder of our ADSs may be able
to mitigate some of the adverse U.S. federal income tax consequences described above with respect to owning the ADSs if we are classified
as a PFIC, provided that such U.S. investor is eligible to make, and validly makes, a “mark-to-market” election. In certain circumstances a
U.S. Holder can make a “qualified electing fund” election to mitigate some of the adverse tax consequences described with respect to an
ownership interest in a PFIC by including in income its share of the PFIC’s income on a current basis. However, we do not currently intend
to prepare or provide the information that would enable a U.S. Holder to make a qualified electing fund election.

Investors should consult their own tax advisors regarding our PFIC status for any taxable year and the potential application of the

PFIC rules to an investment in our ADSs or ordinary shares.

Risks Related to Ownership of our American Depositary Shares (ADSs)

The market price and trading volume of our ADSs may be volatile.

Many factors may have a material adverse effect on the market price of the ADSs, including but not limited to:

●

the commencement, enrollment or results of our planned clinical trials;

the loss of any of our key scientific or management personnel;

sales of our ADSs by us, our executive officers and directors or our shareholders in the future;

general economic and market conditions and overall fluctuations in the U.S. equity markets; and

changes in accounting principles.

In addition, the stock market in general, and Nasdaq and biopharmaceutical companies in particular, have experienced extreme price
and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Broad market
and industry factors may negatively affect the market price of our ADSs, regardless of our actual operating performance. Further, a decline
in the financial markets and related factors beyond our control may cause the price of our ADSs to decline rapidly and unexpectedly. In the
past, securities class action litigation has often been instituted against companies following periods of volatility in their stock price. This
type of litigation could result in substantial costs and could divert our management and other resources.

We may not be able to maintain compliance with the continued listing requirements of Nasdaq.

Our ADSs are listed on Nasdaq. In order to maintain that listing, we must satisfy minimum financial and other requirements

including, without limitation, a requirement that our closing bid price must not fall below $1.00 per ADS for 30 consecutive business days.
In the event that it was necessary to regain compliance with this closing bid price requirement, we would be permitted 180 days in which to
do so and would need to demonstrate that we had maintained a closing bid price of a minimum of $1.00 per ADS for 10 consecutive
business days. In the event that we were unable to regain compliance during this initial 180 day period, or a possible further 180 day period,
we may need to implement reverse stock splits or change the ratio of ADSs to ordinary shares or take other measures in order to regain
compliance with this closing bid price requirement. If we fail to continue to meet all applicable continued listing requirements for Nasdaq in
the future and Nasdaq determines to delist our ADSs, the delisting could adversely affect the market liquidity of our ADSs and our ability to
obtain financing to fund our operations.

Substantial future sales of our ADSs in the public market, or the perception that these sales could occur, could cause the price of the
ADSs to decline and dilute shareholders.

Substantial future sales of our ADSs in the public market, or the perception that these sales could occur, could cause the market
price of the ADSs to decline. Sales of a substantial number of our ADSs in the public market could occur at any time. Moreover, certain
shareholders have rights under an investors rights agreement dated as of February 23, 2015, subject to certain 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
shareholders. In addition, we have registered an aggregate of 151,248,915 ordinary shares that we may issue under our equity compensation
plans and, as a result, they can be freely sold in the public market upon issuance and following conversion into ADSs, but subject to volume
limitations applicable to affiliates under Rule 144. Additionally, the majority of ordinary shares that may be issued under our equity
compensation plans also remain subject to vesting in tranches over a four-year period. As of December 31, 2019, an aggregate of
51,953,196 options over our ordinary shares had vested and become exercisable. If a large number of our ADSs are sold in the public
market after they become eligible for sale, the sales could reduce the trading price of our ADSs and impede our ability to raise capital in the
future.

We incur increased costs as a result of being a public company whose ADSs are publicly traded in the United States and our
management must devote substantial time to public company compliance and other compliance requirements.

As a U.S. public company whose ADSs trade on Nasdaq, we have incurred and will continue to incur significant legal, accounting,

insurance and other expenses. We are subject to the reporting requirements of the Exchange Act, which requires, among other things, that
we file with the SEC annual, quarterly and current reports with respect to our business and financial condition and must comply with the
Nasdaq listing requirements and other applicable securities rules and regulations. In addition, the Sarbanes-Oxley Act, as well as
rules subsequently adopted by the SEC and the Nasdaq to implement provisions of the Sarbanes-Oxley Act, impose significant requirements
on public companies, including requiring establishment and maintenance of effective disclosure and financial controls and changes in
corporate governance practices. Further, pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the SEC
has adopted and will adopt additional rules and regulations, such as mandatory “say on pay” voting requirements, that we must comply
with. We expect the rules and regulations applicable to public companies to substantially increase our legal and financial compliance costs
and to make some activities more time-consuming and costly. Our insurance costs have increased, particularly for directors and officers
liability insurance, and we may be required to incur further substantial increased costs to maintain the same or similar coverage or be forced
to accept reduced coverage in future. To the extent these requirements divert the attention of our management and personnel from other
business concerns, they could have a material adverse effect on our business, financial condition and results of operations. The increased
costs will increase our net loss and may require us to reduce costs in other areas of our business. These laws and regulations could also
make it more difficult and expensive for us to attract and retain qualified persons to serve on our board of directors, our board committees
or as our executive officers. Furthermore, if we are unable to satisfy our obligations as a public company, we could be subject to delisting of
the ADSs from Nasdaq, fines, sanctions and other regulatory action and potentially civil litigation.

If we fail to establish and maintain proper internal controls, our ability to produce accurate financial statements or comply with
applicable regulations could be impaired.

We must maintain effective internal control over financial reporting in order to accurately and timely report our results of

operations and financial condition. In addition, as a U.S. public company, the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act,
requires, among other things, that we assess the effectiveness of our disclosure controls and procedures and the effectiveness of our internal
control over financial reporting at the end of each fiscal period. Pursuant to Section 404 of the Sarbanes-Oxley Act, we are required to
furnish a report by our management on our internal control over financial reporting, and we are required to include an attestation report on
internal control over financial reporting issued by our independent registered public accounting firm. The rules governing the standards that
must be met for our management to assess our internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act
are complex and require significant documentation, testing and possible remediation. These stringent standards require that our audit
committee be advised and regularly updated on management’s review of internal control over financial reporting.

Our compliance with applicable provisions of Section 404 requires that we incur substantial accounting expenses and expend

significant management attention and time on compliance-related issues as we implement additional corporate governance practices and
comply with reporting requirements. If we fail to staff our accounting and finance function adequately or maintain internal control over
financial reporting adequate to meet the requirements of the Sarbanes-Oxley Act, our business and reputation may be harmed. Moreover, if
we are not able to comply with the applicable requirements of Section 404 in a timely manner, we may be subject to sanctions or
investigations by regulatory authorities, including the SEC and Nasdaq. Furthermore, if we are unable to conclude that our internal control
over financial reporting is effective or if our independent registered public accounting firm identifies deficiencies in our internal control
over financial reporting that are deemed to be material weaknesses, we could lose investor confidence in the accuracy and completeness of
our financial reports, the market price of our ADSs could decline, and we could be subject to sanctions or investigations by the SEC,
Nasdaq or other regulatory authorities. Failure to implement or maintain effective internal control systems required of U.S. public
companies could also restrict our access to the capital markets. The occurrence of any of the foregoing would also require additional
financial and management resources.

U.S. investors may have difficulty enforcing civil liabilities against our company, our directors, officers and members of senior
management.

We are incorporated under the laws of England and Wales. The rights of holders of our ordinary shares and, therefore, certain of

the rights of holders of ADSs, are governed by English law, including the provisions of the Companies Act 2006, and by our articles of
association. These rights differ in certain respects from the rights of shareholders in typical U.S. corporations organized in, for example,
Delaware. Some of our directors, officers and members of senior management reside outside the United States, and a substantial portion of
our assets and all or a substantial portion of the assets of such persons are located outside the United States. As a result, it may be difficult
for you to serve legal process on us or our directors and executive officers or have any of them appear in a U.S. court. The United States
and the United Kingdom do not currently have a treaty providing for the recognition and enforcement of judgments, other than arbitration
awards, in civil and commercial matters. The enforceability in the United Kingdom of any judgment of a U.S. federal or state court will
depend on the particular facts of the case as well as the laws and any treaties in effect at the time, including conflicts of laws principles
(such as those bearing on the question of whether a U.K. court would recognize the basis on which a U.S. court had purported to exercise
jurisdiction over a defendant). In this context, there is doubt as to the enforceability in the United Kingdom, in original actions or in actions
for enforcement of judgments of U.S. courts, of civil liabilities based solely on the federal securities laws of the United States. In addition,
awards for punitive damages in actions brought in the United States or elsewhere may be unenforceable in the United Kingdom. An award
for monetary damages under the U.S. securities laws would likely be considered punitive if it did not seek to compensate the claimant for
loss or damage suffered and was intended to punish the defendant.

Provisions in the U.K. City Code on Takeovers and Mergers that may have anti-takeover effects do not apply to us.

The U.K. City Code on Takeovers and Mergers, or the Takeover Code, applies to an offer for, among other things, a public

company whose registered office is in the United Kingdom if the company is considered by the Panel on Takeovers and Mergers, or the
Takeover Panel, to have its place of central management and control in the United Kingdom (or the Channel Islands or the Isle of Man).
This is known as the “residency test.” The test for central management and control under the Takeover Code is different from that used by
the U.K. tax authorities. Under the Takeover Code, the Takeover Panel will determine whether we have our place of central management
and control in the United Kingdom by looking at various factors, including the structure of our Board, the functions of the directors and
where they are resident.

In July 2018, the Takeover Panel confirmed that, based on our current circumstances, we are not subject to the Takeover Code. As
a result, our shareholders are not entitled to the benefit of certain takeover offer protections provided under the Takeover Code. We believe
that this position is unlikely to change at any time in the near future but, in accordance with good practice, we will review the situation on a
regular basis and consult with the Takeover Panel if there is any change in our circumstances which may have a bearing on whether the
Takeover Panel would determine our place of central management and control to be in the United Kingdom.

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

Holders of Common Stock

The Company’s ADSs each represent six ordinary shares of Adaptimmune Therapeutics plc. The ADSs have been listed on

Nasdaq since May 6, 2015 and are traded under “ADAP”. As of February 24, 2020, there were approximately 26 holders of record of our
ordinary shares, par value £0.001 per share, and approximately 10 holders of record of our ADSs. The closing sale price per ADS on
Nasdaq on February 24, 2020 was $3.58.

Dividends

Since our inception, we have not declared or paid any dividends on our ordinary shares. We intend to retain any earnings for use in

our business and do not currently intend to pay dividends on our ordinary shares.

The payment of dividends by Adaptimmune Therapeutics plc is governed by English law. The declaration and payment of any

future dividends will be at the discretion of our board of directors and will depend upon our results of operations, cash requirements,
financial condition, contractual restrictions, restrictions imposed by our indebtedness, any future debt agreements or applicable laws and
other factors that our board of directors may deem relevant.

Recent Sales of Unregistered Securities

We did not sell any unregistered securities during the year ended December 31, 2019.

Table of Contents

to our plans and strategy for our business, includes forward-looking statements that involve risks and uncertainties. As a result of many
factors, including those factors set forth in the “Risk Factors” section of this Annual Report, our actual results could differ materially from
the results described in, or implied by, these forward-looking statements.

Overview

We are a clinical-stage biopharmaceutical company focused on providing novel cell therapies to people with cancer. We are a

leader in the development of T-cell therapies for solid tumors.

Our proprietary SPEAR (Specific Peptide Enhanced Affinity Receptor) T-cell platform enables us to identify cancer targets, find

and genetically engineer T-cell receptors (‘‘TCRs’’) against those targets, and produce therapeutic candidates (‘‘SPEAR T-cells’’) for
administration to patients. Using our affinity engineered TCRs, we aim to become the first company to have a TCR T-cell approved for the
treatment of a solid tumor indication.

Update on Clinical Pipeline Progress

Wholly owned SPEAR T-cells

ADP-A2M4—Multiple Indications: Clinical trials are ongoing with our ADP-A2M4 SPEAR T-cell in multiple indications. In

addition, planning is ongoing for initiation of a clinical trial combining ADP-A2M4 with a PD-1 / PD-L1 pathway inhibitor in 2020.

● A Phase 1 clinical trial in multiple tumor indications, namely urothelial, melanoma, head and neck, ovarian, NSCLC,

esophageal and gastric cancers, synovial sarcoma and MRCLS completed enrollment in early 2020.

● A Phase 2 clinical trial has been initiated in synovial sarcoma and MRCLS. The trial will take place at sites in the United
States, Canada and Europe. The trial will include up to 60 patients at a selected dose of up to 10 billion transduced ADP-
A2M4 SPEAR T-cells. Primary responses will be assessed by overall response rate by RECIST v1.1. The lymphodepletion
regimen will be fludarabine (30mg/m2/day) for 4 days and cyclophosphamide (600 mg/m2/day) for 3 days.

● A radiation sub-study under the Phase 1 clinical trial is continuing at the MD Anderson Cancer Center. The sub-study will
treat up to 10 patients and has a primary endpoint of safety, with RECIST v1.1 responses being a secondary endpoint. The
radiation is a low dose radiation and is administered to lesions or isocenters prior to lymphodepletion.

ADP-A2AFP - Hepatocellular Carcinoma: We continue dosing patients in our Phase 1, open-label, dose-escalation study
designed to evaluate the safety and anti-tumor activity of our alpha fetoprotein (‘‘AFP’’) therapeutic candidate for the treatment of
hepatocellular carcinoma, or HCC. The trial is open in the United States, United Kingdom and the European Union. Patients are now
enrolling in Cohort 3 and are being treated with target doses of 5 billion SPEAR T-cells (range 1.2 to 6 billion).

ADP-A2M4CD8—SURPASS Trial: Enrollment has started in a Phase 1 trial for a next generation SPEAR T-cell, ADP-

A2M4CD8. This next generation SPEAR T-cell utilizes the same engineered T-cell receptor as ADP-A2M4, but with the addition of a
CD8α homodimer. The addition of the CD8α homodimer has been shown in vitro to increase cytokine release and SPEAR T-cell potency.
The SURPASS trial will enroll up to 30 patients across multiple solid tumor indications. Similar to our other trials, the SURPASS trial will
include dose escalation.

ADP-A2M10: Two Phase 1 clinical trials were conducted with ADP-A2M10 for the treatment of (i) NSCLC, and (ii) urothelial,

melanoma and head and neck cancers in the United States, Canada, the United Kingdom and Spain. Enrollment in these trials closed as
planned in 2019.

Ongoing GSK Collaboration Agreement Programs

80

Table of Contents

The third target program under the Collaboration and License Agreement remains ongoing. GSK is currently entitled to nominate
a fourth target program and, upon satisfying other conditions, may have the right to nominate a fifth program under the GSK Collaboration
and License Agreement, in each case excluding our ongoing wholly-owned development programs.

 Recent Events Since December 31, 2019

On January 13, 2020, the Company entered into a co-development and co-commercialization agreement with Astellas Pharma,

Inc. (the “Astellas Collaboration Agreement”). The Company received an upfront payment of $50.0 million in January 2020 under the
agreement and will receive research funding of up to $7.5 million per year from the start of research programs under the agreement.
Additional milestones are possible under the agreement, but these are dependent on the success of the development and commercialization
of research and products.

On January 24, 2020, the Company closed an underwritten public offering of 21,000,000 American Depository Shares (ADSs)
which, together with the full exercise by the underwriters on February 7, 2020 of their option to purchase an additional 3,150,000 ADSs,
generated net proceeds of approximately $89.8 million.

Financial Operations Overview

New standards

On January 1, 2019, we adopted new accounting guidance on lease recognition, which has been codified within Accounting
Standard Codification Topic 842, Leases (“ASC 842”). We adopted the guidance using the modified retrospective approach, with the
cumulative effect of initially applying the guidance recognized as an adjustment to the opening balance of equity at January 1, 2019.
Therefore, the comparative information for the year ended December 31, 2018 and as of December 31, 2018 has not been adjusted and
continues to be reported under previous guidance. The effect on the accumulated deficit, total stockholders’ equity and net assets as at
January 1, 2019 was $0. The adoption of ASC 842 has had a material impact on our financial statements. At January 1, 2019 we recognized
right-of-use assets and liabilities for operating leases following the adoption date of $22.2 million and $26.9 million respectively and
derecognized $4.7 million of other liabilities and prepayments that had been recognized under previous guidance.

Revenue

At December 31, 2019, the Company had one contract with a customer, which is the GSK Collaboration and License Agreement.
The GSK Collaboration and License Agreement consists of multiple performance obligations. GSK nominated its third target under the
Collaboration and License Agreement. The Company received $3.2 million in 2019 following the nomination of the target and development
of products to this target commenced in the year ended December 31, 2019. The development of products to the third target is a separate
performance obligation. Revenue associated with this performance obligation is recognized as the development of products to the target
progresses.

Future revenues will depend on the progress of the development programs within the Collaboration and License Agreement, GSK’s

progress with the NY-ESO program, and progress of development programs within the Astellas Collaboration Agreement, which are
difficult to predict.

Research and Development Expenses

Research and development expenses consist principally of the following:

●

●

salaries for research and development staff and related expenses, including benefits;

costs for production of compounds and drug substances for use in preclinical testing and clinical trials;

81

Table of Contents

●

●

●

●

●

●

●

●

fees and other costs paid to contract research organizations in connection with additional preclinical testing and the
performance of clinical trials;

costs associated with the development of a process to manufacture and supply our lentiviral vector and SPEAR T-cells for use
in clinical trials;

costs for clinical sites and patients

costs to develop manufacturing capability at our U.S. facility for manufacture of SPEAR T-cells for use in clinical trials;

costs relating to facilities, materials and equipment used in research and development;

costs of acquired or in-licensed research and development which does not have alternative future use;

amortization and depreciation of property, plant and equipment and intangible assets used to develop our SPEAR T-cells; and

share-based compensation expenses;

offset by:

●

●

reimbursements from government grants; and

reimbursable tax and expenditure credits from the U.K. government.

Research and development expenditures are expensed as incurred.

Research and development expenditure is presented net of reimbursements from reimbursable tax and expenditure credits from the

U.K. government. As a company that carries out extensive research and development activities, we benefit from the U.K. research and
development tax credit regime for small and medium sized companies (“SME R&D Tax Credit Scheme”), whereby our principal research
subsidiary company, Adaptimmune Limited, is able to surrender the trading losses that arise from its research and development activities
for a payable tax credit of up to approximately 33.4% of eligible research and development expenditures. Qualifying expenditures largely
comprise employment costs for research staff, consumables and certain internal overhead costs incurred as part of research projects for
which we do not receive income. Subcontracted research expenditures are eligible for a cash rebate of up to approximately 21.7%. A large
proportion of costs in relation to our pipeline research, clinical trials management and manufacturing development activities, all of which
are being carried out by Adaptimmune Limited, are eligible for inclusion within these tax credit cash rebate claims.

Expenditures incurred in conjunction with the GSK Collaboration and License Agreement are not qualifying expenditures under the SME
R&D Tax Credit Scheme but certain of these expenditures can be reimbursed through the U.K. research and development expenditure
credit scheme (the “RDEC Scheme”). Under the RDEC Scheme tax relief is given at 12% of allowable R&D costs, which may result in a
payable tax credit at an effective rate of approximately 9.7% of qualifying expenditure.

Our research and development expenses may vary substantially from period to period based on the timing of our research and

development activities, which depends upon the timing of initiation of clinical trials and the rate of enrollment of patients in clinical trials.
The duration, costs, and timing of clinical trials and development of our SPEAR T-cells will depend on a variety of factors, including:

●

the scope, rate of progress, and expense of our ongoing as well as any additional clinical trials and other research and
development activities;

82

Table of Contents

●

●

●

●

●

uncertainties in clinical trial enrollment rates;

future clinical trial results;

significant and changing government regulation;

the timing and receipt of any regulatory approvals; and

supply and manufacture of lentiviral vector and SPEAR T-cells for clinical trials.

For further detail please see Part I — Item 1A Risk Factors — Risks Related to the Development of our SPEAR T-cells of this

Annual Report.

A change in the outcome of any of these variables may significantly change the costs and timing associated with the development
of that SPEAR T cell. For example, if the FDA, or another regulatory authority, requires us to conduct clinical trials beyond those that we
currently anticipate will be required for regulatory approval, 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.

General and Administrative Expenses

Our general and administrative expenses consist principally of:

●

●

●

●

●

●

salaries for employees other than research and development staff, including benefits;

business development expenses, including travel expenses;

professional fees for auditors, lawyers and other consulting expenses;

costs of facilities used for general and administrative use, communication, and office expenses;

information technology expenses;

amortization and depreciation of property, plant and equipment and intangible assets not related to research and development
activities; and

●

share-based compensation expenses.

Other Income (Expense), net

Other income (expense), net primarily comprises foreign exchange gains (losses). We are exposed to foreign exchange rate risk

because we currently operate in the United Kingdom and United States. Our revenue from the GSK Collaboration and License Agreement
is denominated in pounds sterling and is generated by our U.K.-based subsidiary, which has a pounds sterling functional currency. As a
result, these sales are subject to translation into U.S. dollars when we consolidate our financial statements. Our expenses are generally
denominated in the currency in which our operations are located, which are the United Kingdom and United States. However, our U.K.-
based subsidiary incurs significant research and development costs in U.S. dollars and, to a lesser extent, Euros.

Until May 2018, our U.K. subsidiary with a pound sterling functional currency held our investments in marketable securities,
which were predominately denominated in U.S. dollars. The entire change in the fair value of a foreign currency-denominated security,
including the change due to foreign exchange, was included in other comprehensive income. At the end of May 2018, our investments in
marketable securities were transferred from our

83

Table of Contents

U.K. based subsidiary to the ultimate parent company, Adaptimmune Therapeutics plc, which reduced the potential for foreign exchange
gains or losses arising on these investments.

Our U.K. subsidiary has an intercompany loan balance in U.S dollars payable to the ultimate parent company, Adaptimmune

Therapeutics plc. Beginning on July 1, 2019, the intercompany loan was considered of a long-term investment nature as repayment is not
planned or anticipated in the foreseeable future. It is Adaptimmune Therapeutics plc’s intent not to request payment of the intercompany
loan for the foreseeable future. Since July 1, 2019, the foreign exchange gain or losses arising on the revaluation of intercompany loans of a
long-term investment nature are reported within other comprehensive income (loss).  

Our results of operations and cash flows will be subject to fluctuations due to changes in foreign currency exchange rates, which

could harm our business in the future. We seek to minimize this exposure by maintaining currency cash balances at levels appropriate to
meet foreseeable expenses in U.S. dollars and pounds sterling. To date, we have not used hedging contracts to manage exchange rate
exposure, although we may do so in the future.

Taxation

We are subject to corporate taxation in the United Kingdom and the United States. We incur tax losses and tax credit

carryforwards in the United Kingdom. No deferred tax assets are recognized on our U.K. losses and tax credit carryforwards because there
is currently no indication that we will make sufficient taxable profits to utilize these tax losses and tax credit carryforwards. Unsurrendered
U.K. tax losses and tax credit carryforwards can be carried forward to be offset against future taxable profits, however this is restricted to an
annual £5.0 million allowance in each standalone company or group and above this allowance, there will be a 50% restriction in the profits
that can be covered by losses brought forward. There are accumulated tax loss carry forwards and tax credit carryforwards in the United
Kingdom amounting to $249.8 million and $0.7 million as of December 31, 2019. These tax losses and tax credit carryforwards do not
expire.

We benefit from reimbursable tax credits in the United Kingdom through the SME R&D Tax Credit Scheme as well as the RDEC

Scheme which are presented as a deduction to research and development expenditure.

Our subsidiary in the United States has generated taxable profits due to a Service Agreement between our U.S. and U.K. operating

subsidiaries and is subject to U.S. federal corporate income tax of 21% for the year ended December 31, 2019. Due to its activity in the
United States, and the sourcing of its revenue, our U.S. subsidiary is not currently subject to any state or local income taxes.

We also benefit from tax credits arising through the Credit for Increasing Research Activities (“Research Tax Credit”) under the 

U.S. Internal Revenue Code and the U.S. Orphan Drug Credit.  There are accumulated tax credit carryforwards in the United States 
amounting to $5.7 million as of December 31, 2019. These tax credit carryforwards expire after 20 years.

In the future, if we generate taxable income in the United Kingdom, we may benefit from the United Kingdom’s “patent box”

regime, which would allow certain profits attributable to revenues from patented products to be taxed at a rate of 10%. As we have many
different patents covering our products, future upfront fees, milestone fees, product revenues, and royalties may be taxed at this favorably
low tax rate.

U.K. Value Added Tax (“VAT”) is charged on all qualifying goods and services by VAT-registered businesses. An amount of 20%
of the value of the goods or services is added to all relevant sales invoices and is payable to the U.K. tax authorities. Similarly, VAT paid on
purchase invoices paid by Adaptimmune Limited and Adaptimmune Therapeutics plc is reclaimable from the U.K. tax authorities.

Revenue decreased by $58.4 million to $1.1 million in the year ended December 31, 2019 compared to $59.5 million for the year

ended December 31, 2018.  

The revenue recognized for the year ended December 31, 2019 is due to development work of products to the third target nominated
by GSK under the Collaboration and License Agreement. The development and license revenue for the year ended December 31, 2018 was
recognized due to the performance under the NY-ESO transition program and the PRAME development plan, which were completed in
2018.

Future revenues will depend on the progress of the third target program, the development of programs for additional targets, and

GSK’s progress with the NY-ESO program, which are difficult to predict. We estimate that the remaining $2.1 million of revenue from the
$3.2 million received following nomination of the third target should be recognized by the end of 2020 as development progresses.

Salaries, materials, equipment, depreciation of property, plant and equipment and
other employee-related costs(1)
Subcontracted expenditure
Manufacturing facility expenditure
Accrued purchase commitments
Share-based compensation expense
Payments for in-process research and development

The net decrease in our research and development expenses of $0.8 million for the year ended December 31, 2019 compared to

the year ended December 31, 2018 was primarily due to the following:

●

●

●

●

●

●

an increase of $2.7 million in salaries, materials, equipment, depreciation of property, plant and equipment and other employee-
related costs, due to a combination of factors including wage inflation, increased temporary staff costs, and an increase in the
average number of employees engaged in research and development from 320 to 322

a decrease of $8.8 million in subcontracted expenditures, including clinical trial expenses, contract research organization (CRO)
costs and contract manufacturing expenses. This was primarily driven by a decrease in subcontracted expenses and clinical trial
costs due to the transfer of NY-ESO to GSK in 2018

an increase in expenditure of $1.9 million on manufacturing due to increased activity at our U.S. facility in Philadelphia and the
development of a dedicated vector manufacturing capability in Stevenage, Hertfordshire, United Kingdom

an increase of $5.0 million in accrued purchase commitments, which relate to the supply of the Dynabeads® CD3/CD28
technology. Management considered that there is sufficient uncertainty surrounding the future utility of the Dynabeads, which
is dependent upon current clinical trial plans, the Company’s clinical pipeline, manufacturing methods and undetermined future
projects, to result in the purchase commitment being recognized in Research and Development expenses in the period. Further
details of the purchase commitment can be found in Note 9 of the Consolidated Financial Statements.

a decrease of $4.5 million in share-based compensation expense due to forfeitures of share options

an increase of $4.3 million in payments for in-process research and development after entering into collaboration agreements
relating to the development of next-generation SPEAR T-cell products with Alpine Immune Sciences, Inc. on May 14, 2019
and with Noile-Immune Biotech, Inc. on August 26, 2019; and

●

an increase in reimbursements for research and development tax and expenditure credits and government grants of $1.4 million
due to an increase in eligible R&D expenditure and more costs falling within the UK SME R&D scheme.

Our subcontracted costs for the year ended December 31, 2019 were $32.8 million, compared to $41.6 million in the same period
of 2018, of which $18.5 million related to process development for our SPEAR T-cell platform and the remaining $14.3 million related to
our wholly owned pipeline, including ADP-A2M4, ADP-A2M10 and ADP-A2AFP. Our research and development expenses are highly
dependent on the phases and progression of our research projects and future clinical trial results and therefore fluctuate from period to
period.

General and administrative expenses

General and administrative expenses remained flat at $43.4 million for the year ended December 31, 2019 compared to $43.6

million in the same period in 2018. These expenses are not expected to vary as significantly expenses associated with the Company’s other
operating activities; however, the level of such expenses may vary with the success of the Company’s clinical pipeline and any expansion of
operations.

Interest income

Interest income was $2.8 million for the year ended December 31, 2019 compared to $2.8 million for the year ended

December 31, 2018. Interest income primarily relates to interest on cash, cash equivalents and available-for-sale debt securities.

Other income (expense), net

Other income (expense), net was income of $0.1 million for the year ended December 31, 2019 compared to an expense of $15.5

million for the year ended December 31, 2018. Other income (expense), net primarily relates to unrealized foreign exchange gains and
losses on cash and cash equivalents, and intercompany loans held in U.S. dollars by our U.K. subsidiary other than those of a long-term
investment nature, where repayment is not planned or anticipated in the foreseeable future. Beginning on July 1, 2019, the intercompany
loan was considered of a long-term investment nature as repayment is not planned or anticipated in the foreseeable future. It is
Adaptimmune Therapeutics plc’s intent not to request payment of the intercompany loan for the foreseeable future. The foreign exchange
gains or losses arising on the revaluation of intercompany loans of a long-term investment nature are reported within other comprehensive
income (loss).

Income taxes

Income tax expense decreased to $242,000 for the year ended December 31, 2019 from $497,000 for the year ended
December 31, 2018. Income taxes arise in the United States due to our U.S. subsidiary generating taxable profits. We incur losses in the
United Kingdom.

Liquidity and Capital Resources

Sources of Funds

Since our inception, we have incurred significant net losses and negative cash flows from operations. We financed our operations

primarily through sales of equity securities, cash receipts under our GSK Collaboration and License Agreement, government grants and
research and development tax and expenditure credits. From inception through to December 31, 2019, we have raised:

●

●

$513.8 million of proceeds from issues of equity, net of issue costs;

$151.4 million upfront fees, milestones and exercise fees under our GSK Collaboration and License Agreement;

87

Table of Contents

●

●

$2.8 million of income in the form of government grants; and

$40.4 million in the form of U.K. research and development tax credits and receipts from the U.K. RDEC Scheme.

We use a non-GAAP measure, Total Liquidity, which is defined as the total of cash and cash equivalents, short-term deposits and
marketable securities, to evaluate the funds available to us in the near-term. A description of Total Liquidity and reconciliation to cash and
cash equivalents, the most directly comparable U.S. GAAP measure, are provided below under “Non-GAAP measures”.

On January 13, 2020, the Company entered into a co-development and co-commercialization agreement with Astellas Pharma Inc.

The Company received an upfront payment of $50.0 million in January 2020 under the agreement and will receive research funding of up
to $7.5 million per year. In addition, on January 24, 2020, the Company closed an underwritten public offering of 21,000,000 American
Depository Shares (ADSs) which, together with the full exercise by the underwriters on February 7, 2020 of their option to purchase an
additional 3,150,000 ADSs, generated net proceeds of approximately $89.8 million.

As of December 31, 2019, we had cash and cash equivalents of $50.4 million and Total Liquidity of $89.5 million. We believe

that our Total Liquidity, combined with the upfront payment and the recently completed public offering of ADSs described above, will be
sufficient to fund our operations, based upon our currently anticipated research and development activities and planned capital spending,
into the second half of 2021.

During the year ended December 31, 2019, the Company incurred a net loss of $137.2 million, used cash of $112.5 million in its

operating activities, and generated revenues of $1.1 million. The Company has incurred net losses in most periods since inception, and it
expects to incur operating losses in foreseeable future periods.

Management considers that there are no conditions or events, in the aggregate, that raise substantial doubt about the entity’s ability

to continue as a going concern for a period of at least one year from the date the financial statements are issued.

Cash Flows

Net cash used in operating activities increased by $8.1 million to $112.5 million for the year ended December 31, 2019 from
$104.4 million for the year ended December 31, 2018. Net cash used in operating activities is significantly impacted by the timing of
milestone payments received from GSK under the GSK Collaboration and License Agreement. In the year ended December 31, 2019, we
received $3.2 million of milestone payments from GSK compared to $30.2 million in the year ended December 31, 2018. Excluding cash
inflows from the GSK milestone payments and the associated VAT, the cash used in operations decreased in the year ended December 31,
2019. This was primarily due to higher subcontracted expenditure being incurred in 2018 under the GSK Collaboration Agreement.

Components of cash flows from operating activities

Net cash used in operating activities of $112.5 million for the year ended December 31, 2019 comprised a net loss of

$137.2 million offset by $4.7 million of favorable changes in operating assets and liabilities and noncash items of $20.0 million. The
noncash items consisted primarily of depreciation expense on plant and equipment of $7.2 million, amortization of intangibles of $0.8
million, share-based compensation expense of $11.1 million, and unrealized foreign exchange losses of $1.1 million.

Net cash used in operating activities of $104.4 million for the year ended December 31, 2018 comprised a net loss of $95.5 million

and $45.3 million of adverse changes in operating assets and liabilities offset by noncash items of $36.5 million. The noncash items
consisted primarily of depreciation expense on plant and equipment of $7.2 million, share-based compensation expense of $16.2 million and
a realized loss on marketable securities of $2.5 million and unrealized foreign exchange losses of $9.7 million.

Investing Activities

Net cash provided by investing activities was $94.9 million for the year ended December 31, 2019 compared to net cash used in

investing activities of $17.5 million for the year ended December 31, 2018.

Net cash provided by investing activities in the year ended December 31, 2019 included purchases of property and equipment of
$1.6 million, acquisition of intangibles of $1.5 million, investment in marketable securities with maturities greater than three months but
less than 12 months of $27.3 million,  offset by cash inflows from maturity or redemption of marketable securities with maturities greater
than three months but less than 12 months of $125.3 million.  The Company invests surplus cash and cash equivalents in marketable 
securities. In the year ended December 31, 2019, the investments in marketable securities were reduced to fund the Company’s ongoing 
operations.

Net cash used in investing activities in the year ended December 31, 2018, included purchases of property and equipment of $3.9

million, acquisition of intangibles of $0.8 million, and investment in marketable securities with maturities greater than three months but less
than 12 months of $150.8 million, offset by cash inflows from maturity or redemption of marketable securities with maturities greater than
three months but less than 12 months of $138.0 million. In the year ended December 31, 2018, the Company invested surplus cash,
including net proceeds from issuance of shares in marketable securities.

Financing Activities

Net cash provided by financing activities was $0.4 million and $102.7 million for the years ended December 31, 2019 and 2018,

respectively.

Net cash provided by financing activities for the year ended December 31, 2019 consisted of proceeds from exercise of share

options of $0.4 million. As disclosed previously, the Company completed a successful equity offering in January 2020.

Net cash provided by financing activities for the year ended December 31, 2018 consisted of $99.7 million net of issuance costs of

$0.3 million, raised through a registered direct offering in September 2018 and proceeds from exercise of share options of $3.0 million.

Non-GAAP Measures

Total Liquidity (a non-GAAP financial measure)

Total Liquidity (a non-GAAP financial measure) is the total of cash and cash equivalents and marketable securities. Each of these

components appears in the Consolidated Balance Sheet. The U.S. GAAP financial measure

most directly comparable to Total Liquidity is cash and cash equivalents as reported in the consolidated financial statements, which
reconciles to Total Liquidity as follows (in thousands):

We believe that the presentation of Total Liquidity provides useful information to investors because management reviews Total

Liquidity as part of its management of overall liquidity, financial flexibility, capital structure and leverage. The definition of Total
Liquidity includes marketable securities, which are highly liquid and available to use in our current operations.

Off-Balance Sheet Arrangements

During the periods presented, we did not have, and we do not currently have, any off-balance sheet arrangements, as defined in the

rules and regulations of the SEC other than operating leases as described in Note 9 of the consolidated financial statements included in
Item 15 of this Annual Report.

Contractual Obligations

Operating lease obligations

Operating lease obligations primarily consists of minimum lease payments under non-cancellable leases for laboratory and office

property in Oxfordshire, United Kingdom, and Philadelphia, United States.

In May 2017, we entered into an agreement for the lease of a building at Milton Park, Oxfordshire, United Kingdom. The lease

term expires on October 23, 2041, with termination options exercisable by us on the fifth anniversary of the lease commencement date and
at approximately five yearly intervals thereafter.

Purchase obligations

Purchase obligations include signed orders for capital equipment, clinical materials and contract manufacturing, which have been

committed but not yet received and committed funding under the MD Anderson strategic alliance. The timing of the payments may vary
depending on the rate of progress of development and clinical trial enrollment rates. Future clinical trial expenses are not considered
purchase commitments because they are contingent on enrollment in clinical trials and the activities required to be performed by the clinical
sites.

On September 26, 2016, we announced that we had entered into a multi-year strategic alliance with MD Anderson designed to

expedite the development of T-cell therapies for multiple types of cancer. We and MD Anderson are collaborating on a number of studies
including clinical and preclinical development of our SPEAR T-cell therapies targeting NY-ESO and MAGE-A10 and we will collaborate
on future clinical stage first and second generation SPEAR T-cell therapies such as ADP-A2M4 across a number of cancers, including
bladder, lung, ovarian, head and neck, melanoma, synovial sarcoma, esophageal and gastric cancers. Under the terms of the agreement, we
committed at least $19.6 million to fund studies. The Company made an upfront payment of $3,412,000 to MD Anderson in the year ended
December 31, 2017 and milestone payments of $2,325,000 in the year ended December 31, 2018. Payment of this funding is contingent on
mutual agreement to study orders under the alliance agreement and the performance of set milestones by MD Anderson. The timing and
amount of future payments is uncertain.

On June 16, 2016, we entered into a supply agreement with ThermoFisher for the supply of the Dynabeads® CD3/CD28

technology. The Dynabeads® CD3/CD28 technology is designed to isolate, activate and expand human T-cells, and is being used in the
manufacturing of our affinity enhanced T-cell therapies. The supply agreement runs until December 31, 2025. Under the supply agreement,
we are required to purchase our requirements for CD3/CD28 magnetic

90

 
 
Table of Contents

bead product exclusively from ThermoFisher for a period of five years and there are also minimum purchasing obligations (which have
been included in the purchase obligations above). ThermoFisher has the right to terminate the supply agreement for material breach or
insolvency. There are minimum purchasing obligations of $5.0 million, $2.5 million of which payable in 2020 and $2.5 million of which is
payable in 2021, and Adaptimmune has recognized these commitments within Research and development expense in the Statement of
operations for the year ended December 31, 2019 (further details of this are provided in Note 9 of the Financial Statements).

Other obligations

On August 26, 2019, we entered into a collaboration and license agreement relating to the development of next-generation SPEAR

T-cell products with Noile-Immune Biotech Inc (“Noile-Immune”). An upfront exclusive license option fee of $2.5 million was paid to
Noile-Immune in 2019. This has been recognized within Research and Development in the Consolidated Statement of Operations for the
year ended December 31, 2019. Under the agreement, development and commercialization milestone payments up to a maximum of $312
million may be payable if all possible targets are selected and milestones achieved. Noile-Immune would also receive mid-single-digit
royalties on net sales of resulting products.

On May 14, 2019, we entered into a Collaboration Agreement relating to the development of next-generation SPEAR T-cell

products with Alpine Immune Sciences Inc (“Alpine”). We paid an upfront exclusive license option fee of $2.0 million to Alpine in June
2019. Under the agreement, Adaptimmune will pay Alpine for ongoing research and development funding costs and development and
commercialization milestone payments up to a maximum of $288 million, which may be payable if all possible targets are selected and
milestones achieved. The upfront payment of $2.0 million and the payments for ongoing research are recognized within Research and
development. Alpine would also receive low single-digit royalties on worldwide net sales of applicable products.

On November 25, 2015, we entered into a Research Collaboration and License Agreement relating to gene editing and HLA-

engineering technology with Universal Cells. We paid an upfront license fee of $2.5 million to Universal Cells. A milestone payment of
$3.0 million was made in February 2016 and further milestone payments of $0.2 million and $0.9 million were made in the year ended
December 31, 2018 and 2017, respectively. The agreement was amended and re-stated as at January 13, 2020, primarily to reflect changes
to the development plan agreed between the parties. Further milestone payments of up to $38.4 million if certain development and product
milestones are achieved. Universal Cells would also receive a profit-share payment for the first product, and royalties on sales of other
products utilizing its technology.

In 2012, we entered into a series of license and sub-license agreements with Life Technologies Corporation, part of ThermoFisher
that provide us with a field-based exclusive license under certain intellectual property rights owned or controlled by ThermoFisher. We paid
upfront license fees of $1.0 million relating to the license and sublicense agreements and are obligated to pay minimum annual royalties (in
the tens of thousands of U.S. dollars prior to licensed product approval and thereafter at a level of 50% of running royalties in the
previous year), milestone payments and a low single-digit running royalty payable on the net selling price of each licensed product.

Critical Accounting Policies and Significant Judgments and Estimates

We have prepared our consolidated financial statements in accordance with U.S. GAAP. Our preparation of these consolidated

financial statements requires us to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities,
expenses and related disclosures at the date of the consolidated financial statements, as well as revenue and expenses during the reporting
periods. We evaluate our estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various
other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the
carrying value of assets and liabilities that are not readily apparent from other sources. Actual results could therefore differ materially from
these estimates under different assumptions or conditions.

91

Table of Contents

While our significant accounting policies are described in more detail in Note 2 to our consolidated financial statements, we

believe the following accounting policies to be critical to the judgments and estimates used in the preparation of our financial statements.

Revenue Recognition

The Company has one contract with a customer, which is the GSK Collaboration and License Agreement. The GSK Collaboration

and License Agreement consists of multiple performance obligations, including the transition of the NY-ESO SPEAR T-cell program to
GSK, the development of a second target, PRAME, the NY-ESO License, and following its nomination in 2019, a third target under the
Agreement.

The Company determines the variable consideration to be included in the transaction price by estimating the most-likely amount that 

will be received and then applies a constraint to reduce the consideration to the amount which is probable of being received.  In estimating 
the amount of variable consideration to be included in the transaction price, the Company considers the latest project plan and other 
available information. The determination of whether a milestone is probable includes consideration of the following factors:

● whether achievement of a development milestone is highly susceptible to factors outside the entity’s influence, such as milestones

involving the judgment or actions of third parties, including regulatory bodies or the customer;

● whether the uncertainty about the achievement of the milestone is not expected to be resolved for a long period of

time;

● whether the Company can reasonably predict that a milestone will be achieved based on previous experience;

and

●

the complexity and inherent uncertainty underlying the achievement of the
milestone.

The determination of whether future milestones are probable requires significant judgment and the impact of a change in the 

determination of whether a milestone is probable is recognized in the period the judgment is revised.  This can significantly impact the 
revenue recognized.  In the year ended December 31, 2018, revenue of $10.4 million, was recognized due to development milestones 
becoming probable in the period. No significant changes to this assessment of the probability of further milestones being met in relation to 
GSK’s development of NY-ESO occurred during the year ended December 31, 2019. As the development program progresses and the 
uncertainties underlying the milestones resolve, further milestones may become probable.

Upfront payments are allocated between the performance obligations using the Company’s best estimate of the relative selling price

of each performance obligation. The best estimate of the selling price is determined after considering all reasonably available information,
including internal pricing objectives used in negotiating the contract, together with internal data regarding the cost and margin of providing
services for each deliverable taking into account the different stage of development of each development program. The variable
consideration is allocated to the performance obligation to which it relates.

The amount of the transaction price allocated to the performance obligation is recognized as or when the Company satisfies the 

performance obligation.  The Company satisfied the performance obligations relating to the transition of the NY-ESO SPEAR T-cell 
program and the development of a second target, PRAME, over time and recognized revenue based on an estimate of the percentage of 
completion of the project determined based on the costs incurred on the project as a percentage of the total expected costs. The NY-ESO 
transition and the PRAME pre-clinical development program were completed in 2018.

The performance obligation relating to the NY-ESO License was recognized at a point-in-time, upon commencement of the license

in September 2018.

92

Table of Contents

In 2019, GSK has nominated its third target under the Collaboration and License Agreement. Development of products to this

target commenced in the year ended December 31, 2019, and the Company received $3.2 million following the nomination of the target.
The development of products to the third target is a separate performance obligation, for which revenue expected to be recognized by the
end of 2020 as the development progresses. $1.1 million of revenue related to this target was recognized in the year ended December 31,
2019. Future revenues will depend on the progress of the development programs within the Collaboration and License Agreement, and
GSK’s progress with the NY-ESO program, which are difficult to predict.

Clinical Trial Expenses

Expenses related to clinical trials are recognized as services are received. Nonrefundable advance payments for services are
deferred and recognized in the statement of operations as the services are rendered. This determination is based on an estimate of the
services received and there may be instances when the payments to vendors exceed the level of services provided resulting in a prepayment
of the clinical expense. If the actual timing of the performance of services varies from our estimate, the accrual or prepaid expense is
adjusted accordingly.

As part of the process of preparing our financial statements, we are required to estimate our accrued expenses. This process
involves reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed on
our behalf, and estimating the level of service performed and the associated cost incurred for the service when we have not yet been
invoiced or otherwise notified of the actual cost. The majority of our service providers invoice us monthly in arrears for services performed.
We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on facts and circumstances
known to us at that time. We may confirm the accuracy of our estimates with the applicable service providers and make adjustments if
necessary. Examples of estimated accrued research and development expenses include fees paid to: CROs in connection with clinical trials;
operators of investigative sites in connection with clinical trials; vendors in connection with preclinical development activities; and vendors
related to product manufacturing, development and distribution of clinical supplies.

We base our expenses related to clinical trials on our estimates of the services received and efforts expended pursuant to contracts

with multiple CROs that conduct and manage clinical trials on our behalf. The financial terms of these agreements are subject to
negotiation, vary from contract to contract, and may result in uneven payment flows. Payments under some of these contracts depend on
factors such as the successful enrollment of subjects and the completion of clinical trial milestones. In accruing service fees, we estimate the
time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the
performance of services or the level of effort varies from our estimate, we adjust the accrual or prepaid amount accordingly.

There may be instances in which payments made to our vendors will exceed the level of services provided and result in a
prepayment of the clinical expense. For example, the strategic alliance with MD Anderson involves milestone payments made in advance of
the service being provided. In recognizing the expense, we estimate the cost by patient enrolled and recognize this over the period between
initial dosing and estimated cessation of patient monitoring activities. The duration of the clinical trial is estimated based on internal
historical data and projections. There is limited data available and our estimate of the duration of the clinical may vary as we obtain further
data.

Although we do not expect our estimates of the amounts, status and timing of services performed to be materially different from

the actual amounts, status and timing of services performed, if they do vary, we may report amounts that are too high or too low in any
particular period. To date, there has been no material difference between our estimates and the amount actually incurred.

Clinical materials

Clinical materials for use in research and development with alternative future use are capitalized as either other current assets or 
other non-current assets, depending on the timing of their expected consumption.  The clinical materials with alternative future use consist
of Dynabeads® CD3/CD28 technology (“Dynabeads”), which is designed to isolate, activate and expand human T-cells, and is being used
in the manufacturing of the Company’s affinity enhanced T-cell

93

Table of Contents

therapies.  The Dynabeads are purchased under a supply agreement, which runs until December 31, 2025. The supply agreement includes
minimum purchasing obligations.

As of December 31, 2019, we have $4.0 million of clinical materials, of which we expect to consume $1.5 million within the next 
12 months and the remaining amount over the next several years.  At each reporting date, we consider whether the Dynabeads on-hand and 
committed purchase obligations are impaired due to excess quantity over current forecast demand by considering manufacturing forecasts, 
forecasts of clinical trial enrollments, stability testing results, technological developments and future development programs.  There are 
minimum purchasing obligations of $5.0 million, $2.5 million of which payable in 2020 and $2.5 million of which is payable in 2021. 
Management regularly updates the assessment of the utility of the Dynabeads, and in the year ended December 31, 2019, considers that 
there is sufficient uncertainty surrounding the utility of the Dynabeads, which is dependent upon current study trajectories, the Company’s 
clinical pipeline, manufacturing methods and undetermined future projects, to result in the $5.0 million purchase commitment being 
recognized in Research and development. 

Operating Leases (Incremental Borrowing Rate)

Since the rates implicit in our leases are not readily determinable, we use the Company’s incremental borrowing rates (the rate of

interest that we would have to pay to borrow on a collateralized basis over a similar term for an amount equal to the lease payments in a
similar economic environment) based on the information available at commencement date in determining the discount rate used to calculate
the present value of lease payments. As we have no external borrowings, the incremental borrowing rates are determined using information
on indicative borrowing rates that would be available to us based on the value, currency and borrowing term provided by financial
institutions, adjusted for company and market specific factors.

Although we do not expect our estimates of the incremental borrowing rates to generate material differences within a reasonable
range of sensitivities, judgement is involved in selecting an appropriate rate, and the rate selected for each lease will have an impact on the
value of the lease liability and corresponding right-of-use (ROU) asset in the Consolidated Balance Sheets.

U.K. R&D Tax and Expenditure Credits

Research and development expenditure is presented net of reimbursements from the U.K. Small and Medium-sized Entity R&D

Tax Credit Scheme and the U.K. Research and Development Expenditure Credit Scheme. Reimbursable tax and expenditure credits are
recognized when it is probable that the Company has complied with any attached conditions and will receive the reimbursement.
Management is required to develop estimates at each reporting date on the amount of the reimbursable tax and expenditure credits, which
includes an estimate of qualifying expenditure. The tax and expenditure credits are claimed from Her Majesty’s Revenue and Customs
(“HMRC”) as part of the annual U.K. tax return. Although, we do not expect our estimates to be materially different from amounts claimed
and subsequently reimbursed by HMRC, if our estimates of the qualifying expenditure differ from the amount claimed, we may report
amounts that are too high or too low in any particular period. To date, there has been no material differences between our estimates and the
amount actually reimbursed.

U.S. Research Tax Credits and Orphan Drug Credit

In 2018, the Company estimated that it would benefit from Research Tax Credits and Orphan Drug Credits of $2.0 million for

the year ended December 31, 2018, of which $0.7 million would offset taxes in the year ended December 31, 2018. As of
December 31, 2019, the Company estimated that it will benefit from Research Tax Credits and Orphan Drug Credits of $1.8 million for
the year ended December 31, 2019, of which $0.6 million will offset taxes in the year ended December 31, 2019. Although we do not
expect our estimates to be materially different from amounts claimed, if our estimates of the qualifying expenditure differ from the amount
claimed, we may report amounts that are too high or too low in any particular period.

Deferred taxes

Deferred tax is accounted for using the asset and liability method that requires the recognition of deferred tax assets and liabilities

for the expected future tax consequences of temporary differences between the financial statement carrying amount and the tax bases of
assets and liabilities at the applicable tax rates. As of December 31, 2019, we have deferred tax assets of $62.9 million, offset by deferred
tax liabilities of $3.7 million and a valuation allowance of $59.2 million.

A valuation allowance is provided when it is more-likely-than-not that some portion or all of the deferred tax assets will not be

realized. Future realization of the tax benefit of a deferred tax asset depends on the existence of sufficient taxable income of the appropriate
character (for example, ordinary income or capital gain) within the carryback or carryforward period available under the tax law. The
Company considers the following possible sources of taxable income when assessing whether there is sufficient taxable income to realize a
tax benefit for deductible temporary differences and carryforwards:

●

●

●

●

future reversals of existing taxable temporary differences;

future taxable income exclusive of reversing temporary differences and carryforwards;

taxable income in prior carryback year(s) if carryback is permitted under the tax law; and

tax-planning strategies.

The Company considers both positive and negative evidence regarding realization of the deferred tax assets and the subjectivity of

this evidence. This assessment includes estimating future taxable income, scheduling reversals of temporary differences, evaluating
expectations of future profitability, determining refund potential in the event of net operating loss carrybacks, and evaluating potential tax-
planning strategies.

The Company has generated losses in the United Kingdom since inception and is forecasted to generate tax losses for the next

several years and therefore the deferred tax assets arising in the United Kingdom are only considered more-likely-than-not of being realized
to the extent that reversing temporary taxable differences are available.

The U.S. subsidiary has generated taxable income since the fiscal year ended June 30, 2014 due to a Service Agreement between
our U.S. and U.K. operating subsidiaries and is forecast to generate taxable income in future periods. In determining whether the deferred
tax asset is more-likely-than-not of being recognized, the Company has taken into account the short history of taxable profits, the forecast of
future taxable income, including whether future originating temporary deductible differences are likely to be realized, and the reversal of
temporary taxable deductions. Several of the temporary deductible differences reverse over a long time period, such as those relating to
share-based compensation expense, which the Company forecasts are likely to reverse predominately in 2020 and beyond. The Company
considers that forecasting taxable income beyond the next few years is very subjective due to the nature and extent of the development
process subcontracted from the Company in the United Kingdom to the U.S. subsidiary. Less weight has been given to forecasts of taxable
income beyond the next few years. The deferred tax asset arising in the United States is only considered more-likely-than-not of being
realized to the extent that there are available reversing temporary taxable differences. The Company’s analysis is subject to estimates and
judgments particularly relating to the timing of the reversal of temporary deductible differences for stock compensation expense and the
availability of future taxable income beyond the next few years, which depend on the nature and extent of the subcontract development
work performed by the U.S. subsidiary.

Share-based Compensation

The Company awards certain employees options over the ordinary shares of the parent company. The cost of share-based awards

issued to employees is measured at the grant-date fair value of the award and recognized as an expense over the requisite service period, for
those awards that are ultimately expected to vest. The fair value of the

95

Table of Contents

options is determined using the Black-Scholes option-pricing model. Share options with graded-vesting schedules are recognized on a
straight-line basis over the requisite service period for each separately vesting portion of the award.

Valuation of Share Options

The Black-Scholes option pricing model requires the input of assumptions, including share price volatility, the expected term of a

share option, the risk free rate and the underlying share valuation. The assumption of the expected term of share options involves
management judgment. We estimate that the expected life of our share options, which is the time from the grant date to the expected
exercise date, is five years. The life of the options depends on the option expiration date, volatility of the underlying shares and vesting
features. We do not have sufficient history to determine the expected life based on internal data and therefore the estimate is based on
empirical data.

Item 9A.  Controls and Procedures

Disclosure Controls and Procedures.

Our management, with the participation of our Chief Executive Officer and Interim Chief Financial Officer, has evaluated the
effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the
period covered by this Annual Report.

Based on such evaluation, our Chief Executive Officer and Interim Chief Financial Officer have concluded that our disclosure

controls and procedures were effective to ensure that information required to be disclosed by us in the reports that we file or submit under
the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and is
accumulated and communicated to our management, including our Chief Executive and Interim Chief Financial Officer, or persons
performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

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 such term is

defined in Securities Exchange Act Rule 13a-15(f). Because of its inherent limitations, internal control over financial reporting may not
prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonably assurance of
achieving their control objectives. Under the supervision and with the participation of our management, including our Chief Executive
Officer and Interim Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting
based on the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the
Treadway

96

Table of Contents

Commission. Based on our evaluation under the framework, our management concluded that our internal control over financial reporting
was effective as of December 31, 2019.

KPMG, LLP, the independent registered public accounting firm who audited the Company’s Consolidated Financial Statements

included in this Form 10-K, has issued a report on the Company’s internal control over financial reporting, which is included in Item 15 of
this Form 10-K.

Changes in Internal Control Over Financial Reporting.

There has been no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act)

that occurred during the fourth quarter of 2019 that has materially affected, or is reasonably likely to materially affect, internal control over
financial reporting.

In January 2019, the Company has adopted new guidance on lease accounting, which has been codified within Accounting
Standard Codification Topic 842, Leases (“ASC 842”). As a consequence of the new guidance, the Company has implemented several new
internal controls.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors Adaptimmune Therapeutics plc:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Adaptimmune Therapeutics plc and subsidiaries (the
Company) as of December 31, 2019 and 2018, the related consolidated statements of operations, comprehensive loss, changes in equity,
and cash flows for each of the years in the two-year period ended December 31, 2019, 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, 2019 and 2018, and the results of its operations and its cash flows for each of the years in the two-year
period ended December 31, 2019, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States)
(PCAOB), the Company’s internal control over financial reporting as of December 31, 2019, based on criteria established in Internal
Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our
report dated February 27, 2020 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial
reporting.

Change in Accounting Principles

As discussed in Note 2 to the consolidated financial statements, the Company changed its method of accounting for leases as of

January 1, 2019 due to the adoption of Accounting Standard Codification Topic 842, Leases, and changed its method of accounting for
revenue from contracts with customers as of January 1, 2018 due to the adoption of Accounting Standard Codification Topic 606, Revenue
from Contracts with Customers.

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 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. 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.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial

statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures
that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The
communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and
we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or
disclosures to which they relate.

Table of Contents

Evaluation of the incremental borrowing rates used to measure the right-of-use assets and operating lease liabilities upon

adoption of ASC Topic 842.

As discussed in Note 2 and Note 8 to the consolidated financial statements, the Company recorded operating lease right-of-use 
(ROU) assets and operating lease liabilities of $22.2 million and $26.9 million, respectively, at January 1, 2019. The rate implicit in the 
lease is not readily determinable, therefore, the Company uses incremental borrowing rates to measure the present value of lease payments. 
The incremental borrowing rates are developed using information on indicative borrowing rates adjusted for company and market specific 
factors.   

We identified the evaluation of incremental borrowing rates used to measure ROU assets and operating lease liabilities upon 

adoption of ASC Topic 842 as a critical audit matter. It required especially challenging auditor judgement and specialized skills and 
knowledge to assess the incremental borrowing rates since the company does not have any external borrowings.  

The primary procedures we performed to address this critical audit matter included the following.

We involved valuation professionals with specialized skills and knowledge, who assisted in:

●

Evaluating the Company’s indicative borrowing rate by comparing it to a borrowing rate independently developed
using publicly available market data for comparable entities, and

● Developing a synthetic credit rating which was adjusted for market data of comparable companies to determine an

independent range of incremental borrowing rates. The synthetic credit rating approach compared financial ratios of
the Company to the ratios of other comparable public companies with established credit ratings. The model
determined a median value for each financial ratio at each credit rating and then a simple average score for each
financial ratio was calculated to determine a range of overall credit ratings.

We performed sensitivity analyses by comparing the Company’s incremental borrowing rates to that of the independently

developed range noted above to evaluate the impact on the Company’s measurement of the ROU assets and operating lease liabilities

Evaluation of clinical materials and related committed purchase obligation impairment analysis

As discussed in Notes 2, 5, and 10 to the consolidated financial statements, the Company has clinical materials of $4.0 million as 

of December 31, 2019 and a related accrued purchase commitments of $5.0 million, of which $2.5 million is payable in 2020 and $2.5 
million is payable in 2021. The Company assesses the clinical materials and related committed purchase obligations for impairment at each 
reporting date and whenever events or changes in circumstances indicate that an asset’s carrying amount may not be recoverable, 
considering the on-hand materials and committed purchase obligations. During the year ended December 31, 2019 the Company recognized 
$5.0 million of accrued purchase commitments and research and development expense relating to the uncertainty surrounding the utilisation 
of clinical materials.  

We identified the evaluation of clinical materials and related committed purchase obligations impairment analysis as a critical

audit matter. A high degree of auditor judgement was required in assessing the Company’s assumptions within the manufacturing forecasts
relating to the shelf life of clinical materials and forecasts of clinical trial enrollments used to estimate future clinical material utilization.

The primary procedures we performed to address this critical audit matter included the following:

● We tested certain internal controls over the Company’s process for assessing the impairment of clinical materials and

committed purchase obligations, including controls over the development of assumptions listed above to estimate future
clinical material utilization.

F-3

Table of Contents

● We evaluated the Company’s ability to accurately estimate the clinical material utilization by comparing historically

estimated future utilization to actual results.

● We assessed the assumptions, listed above, in the impairment analysis through a combination of inquiry of finance and
operations personnel and inspection of manufacturing budgets to assess the impact of clinical trial enrollment, current
quantities on hand, and forecasted future demand of clinical materials.

● We examined the Company’s assumption of shelf life of the clinical materials into the manufacturing forecasts by

obtaining third party confirmations of stability testing results.

● We performed sensitivity analyses of the clinical trial enrollments and the timeline to utilize the clinical materials to

evaluate their impact on the Company’s clinical material impairment analysis.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors Adaptimmune Therapeutics Plc:

Opinion on Internal Control Over Financial Reporting

We have audited Adaptimmune Therapeutics plc and subsidiaries’ (the Company) internal control over financial reporting as of

December 31, 2019, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of
Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal
control over financial reporting as of December 31, 2019, based on criteria established in Internal Control – Integrated Framework (2013) 
issued by the Committee of Sponsoring Organizations of the Treadway Commission.  

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States)
(PCAOB), the consolidated balance sheets of the Company as of December 31, 2019 and 2018, the related consolidated statements of
operations, comprehensive loss, changes in equity, and cash flows for each of the years in the two-year period ended December 31, 2019,
and the related notes (collectively, the consolidated financial statements), and our report dated February 27, 2020 expressed an unqualified
opinion on those consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its
assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on
Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial
reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect
to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange
Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the

audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material
respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial
reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal
control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the
circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the

reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted
accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the
maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company;
(2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with
generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with
authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection
of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also,

projections of any evaluation of effectiveness to future periods are subject to the risk that controls

may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Note 1 — General

ADAPTIMMUNE THERAPEUTICS PLC
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Adaptimmune Therapeutics plc is registered in England and Wales. Its registered office is 60 Jubilee Avenue, Milton Park, 
Abingdon, Oxfordshire, OX14 4RX, United Kingdom.  Adaptimmune Therapeutics plc and its subsidiaries (collectively “Adaptimmune” or 
the “Company”) is a clinical-stage biopharmaceutical company primarily focused on providing novel cell therapies to people with cancer.
We are a leader in the development of T-cell therapies for solid tumors. The Company’s proprietary SPEAR (Specific Peptide Enhanced
Affinity Receptor) T-cell platform enables it to identify cancer targets, find and genetically engineer T-cell receptors (“TCRs”) against
those targets, and produce therapeutic candidates (“SPEAR T-cells”) for administration to patients.

The Company is subject to a number of risks similar to other biopharmaceutical companies in the early stage of clinical
development including, but not limited to, the need to obtain adequate additional funding, possible failure of preclinical programs or clinical
programs, the need to obtain marketing approval for its SPEAR T-cells, competitors developing new technological innovations, the need to
successfully commercialize and gain market acceptance of the Company’s SPEAR T-cells, the need to develop a reliable commercial
manufacturing process, the need to commercialize any T-cell therapies that may be approved for marketing, and protection of proprietary
technology. If the Company does not successfully commercialize any of its SPEAR T-cells, it will be unable to generate product revenue or 
achieve profitability.  The Company had an accumulated deficit of $455.7 million as of December 31, 2019.

Note 2 — Summary of Significant Accounting Policies

(a)          Basis of presentation

The Consolidated Financial Statements of Adaptimmune Therapeutics plc and its subsidiaries and other financial information
included in this Annual Report have been prepared in accordance with generally accepted accounting principles in the United States of 
America (“US GAAP”) and are presented in U.S. dollars.  All significant intercompany accounts and transactions between the Company 
and its subsidiaries have been eliminated on consolidation.

(b)          Use of estimates in financial statements

The preparation of financial statements, in conformity with U.S. GAAP and SEC regulations, requires management to make

estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date
of the Consolidated Financial Statements and reported amounts of revenues and expenses during the reporting period. Estimates and
assumptions are primarily made in relation to the valuation of share options, valuation allowances relating to deferred tax assets, revenue
recognition, assessment of the utility of clinical materials, estimation of the incremental borrowing rate for operating leases, estimating
clinical trial expenses and estimating R&D tax and expenditure credits. If actual results differ from the Company’s estimates, or to the
extent these estimates are adjusted in future periods, the Company’s results of operations could either benefit from, or be adversely affected
by, any such change in estimate.

(c)          Going concern

In accordance with Accounting Standards Codification (“ASC”) 205-40, Going Concern, the Company has evaluated whether

there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going
concern within one year after the date the financial statements are issued.

As of December 31, 2019, the Company had cash and cash equivalents of $50.4 million, marketable securities of $39.1 million, and
stockholders’ equity of $123.6 million. On January 13, 2020, the Company entered into a co-development

F-12

and co-commercialization agreement with Astellas Pharma Inc. and received an upfront payment of $50.0 million in January 2020 under
the agreement. The Company is also entitled to receive research funding of up to $7.5 million per year. On January 24, 2020, the Company
closed an underwritten public offering of 21,000,000 American Depository Shares (ADSs) which, together with the full exercise by the
underwriters on February 7, 2020 of their option to purchase an additional 3,150,000 ADSs, generated net proceeds of approximately $89.8
million. These events resolved the conditions previously reported in our Form 10-Q for the three months ended September 30, 2019 that had
raised substantial doubt about the Company’s ability to continue as a going concern for a period of at least one year from the date the
financial statements were issued.

During the year ended December 31, 2019, the Company incurred a net loss of $137.2 million, used cash of $112.5 million in its
operating activities, and generated revenues of $1.1 million. The Company has incurred net losses in most periods since inception, and it
expects to incur operating losses in future periods.

Management considers that there are no conditions or events, in the aggregate, that raise substantial doubt about the entity’s ability

to continue as a going concern for a period of at least one year from the date the financial statements are issued. Although our financial
statements have been prepared on a going concern basis, if the Company fails to obtain additional financing in future, this may raise
substantial doubt over the Company’s ability to continue as a going concern in future reporting periods.

(d)          Foreign currency

The reporting currency of the Company is the U.S. dollar.  The Company has determined the functional currency of the ultimate
parent company, Adaptimmune Therapeutics plc, is U.S. dollars because it predominately raises finance and expends cash in U.S. dollars. 
The functional currency of subsidiary operations is the applicable local currency.  Transactions in foreign currencies are translated into the
functional currency of the subsidiary in which they occur at the foreign exchange rate in effect on at the date of the transaction.  Monetary
assets and liabilities denominated in foreign currencies at the balance sheet date are translated into the functional currency of the relevant
subsidiary at the foreign exchange rate in effect on the balance sheet date. Foreign exchange differences arising on translation are
recognized within other income (expense) in the Consolidated Statement of Operations.

At the end of May 2018, the Company’s investments in marketable securities were transferred to the ultimate parent company,
Adaptimmune Therapeutics plc, with a U.S. dollar functional currency, which reduced the potential for foreign exchange gains or losses
arising on these investments.

The Company’s U.K. subsidiary has an intercompany loan balance in U.S dollars payable to the ultimate parent company,

Adaptimmune Therapeutics plc. Beginning on July 1, 2019, the intercompany loan was considered of a long-term investment nature as
repayment is not planned or anticipated in the foreseeable future. It is Adaptimmune Therapeutics plc’s intent not to request payment of the
intercompany loan for the foreseeable future. The foreign exchange gain or losses arising on the revaluation of intercompany loans of a
long-term investment nature are reported within other comprehensive income (loss).  

The results of operations for subsidiaries, whose functional currency is not the U.S. dollar, are translated at an average rate for the
period where this rate approximates to the foreign exchange rates ruling at the dates of the transactions and the balance sheet are translated
at foreign exchange rates ruling at the balance sheet date. Exchange differences arising from this translation of foreign operations are
reported as an item of other comprehensive income (loss).

Foreign exchange losses were $137,000 and $15,257,000 for the years ended December 31, 2019 and 2018, respectively, and are

included within Other income (expense), net in the Consolidated Financial Statements.

(e)          Fair value measurements

The Company is required to disclose information on all assets and liabilities reported at fair value that enables an assessment of

the inputs used in determining the reported fair values. The fair value hierarchy prioritizes valuation inputs based on the observable nature
of those inputs. The hierarchy defines three levels of valuation inputs:

Level 1 — Quoted prices in active markets for identical assets or liabilities

Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or
indirectly

Level 3 — Unobservable inputs that reflect the Company’s own assumptions about the assumptions market participants would use
in pricing the asset or liability

The carrying amounts of the Company’s cash and cash equivalents, restricted cash, accounts receivable, accounts payable and
accrued expenses approximate fair value because of the short-term nature of these instruments. The fair value of marketable securities,
which are measured at fair value on a recurring basis is detailed in Note 4, Financial Instruments.

The Company considers all highly liquid investments with a maturity at acquisition date of three months or less to be cash

equivalents. Cash and cash equivalents comprise cash balances, commercial paper and corporate debt securities with maturities of three
months or less at acquisition and short deposits with maturities of three months or less.

The Company’s restricted cash consists of cash providing security for letters of credit in respect of lease agreements and credit

cards.

Management determines the appropriate classification of its investments in available-for-sale debt securities at the time of purchase
and reevaluates such designation as of each reporting date. The securities are classified as current or non-current based on the maturity dates
and management’s intentions.

At December 31, 2019, the Company has classified all of its available-for-sale debt securities, including those with maturities

beyond one year, as current assets on the accompanying Consolidated Balance Sheets based on the

F-15

highly-liquid nature of these investment securities and because these investment securities are considered available for use in current
operations.

The investment in available-for-sale debt securities is measured at fair value at each reporting date.  Unrealized gains and losses 

are excluded from earnings and are reported as a component of comprehensive loss. Realized gains and losses, interest income and 
amortization of premiums and discounts at acquisition are included in other income (expense), net.  In the year ended December 31, 2019 
and 2018, proceeds from the maturity or redemption of available-for-sale debt securities were $125,303,000 and $138,038,000 respectively.
There were realized gains (losses) of $13,000 and $(2,473,000) recognized on the maturity of available-for-sale debt securities during the
year ended December 31, 2019 and 2018, respectively, primarily arising due to foreign exchange movements, and, as a result, the Company
reclassified this amount out of accumulated other comprehensive loss for the same period.

At each reporting date, the Company assesses whether each individual investment is impaired, which occurs if the fair value is less 

than the amortized cost, adjusted for amortization of premiums and discounts at acquisition.  If the investment is impaired, the impairment 
is assessed to determine if it is other than temporary. Impairments judged to be other than temporary are included in other income 
(expense), net when they are identified. 

The aggregate fair value (in thousands) and number of securities held by the Company in an unrealized loss position as of

December 31, 2019 and 2018 are as follows:

As of December 31, 2019 and 2018, these securities are not considered to be other than temporarily impaired because the
impairments are not severe, have been for a short duration and are due to normal market and exchange rate fluctuations. No securities have
been in an unrealized loss position for more than one year. Furthermore, the Company does not intend to sell the debt securities in an
unrealized loss position, and it is unlikely that the Company will be required to sell these securities before the recovery of the amortized
cost.

The cost of securities sold is based on the specific-identification method. Interest on debt securities is included in interest income.

Our investment in available-for-sale debt securities is subject to credit risk.  The Company’s investment policy limits investments 

to certain types of instruments, such as money market instruments and corporate debt securities, places restrictions on maturities and 
concentration by type and issuer and specifies the minimum credit ratings for all investments and the average credit quality of the portfolio.

(i)           Accounts receivable

Accounts receivable are amounts due from customers. As of December 31, 2019 and 2018, the Company had one customer, which

was GlaxoSmithKline, or GSK.

Management analyses current and past due accounts and determines if an allowance for uncollectible accounts is required based
on collection experience and other relevant information. As of December 31, 2019 and 2018, the allowance for doubtful accounts is $nil.
The process of estimating the uncollectible accounts involves assumptions and judgments and the ultimate amounts of uncollectible
accounts receivable could be in excess of the amounts provided.

Table of Contents

(j)          Clinical materials

Clinical materials for use in research and development with alternative future use are capitalized as either other current assets or
other non-current assets, depending on the timing of their expected consumption. The Company assesses whenever events or changes in
circumstances indicate that an asset’s carrying amount may not be recoverable. The Company also assesses whether there is an expected
decline in the utility of materials to be purchased under future commitments at the end of each reporting period. Further information is
disclosed in Note 9.

(k)           Property, plant and equipment

Property, plant and equipment is stated at cost, less any impairment losses, less accumulated depreciation.

Depreciation is computed using the straight-line method over the estimated useful lives of the related assets. The following table

provides the range of estimated useful lives used for each asset type:

Computer equipment
Laboratory equipment
Office equipment
Leasehold improvements

     3 to 5 years

Assets under construction are not depreciated until the asset is available and ready for its intended use.

The Company assesses property, plant and equipment for impairment whenever events or changes in circumstances indicate that

an asset’s carrying amount may not be recoverable.

(l)        Intangibles

Intangibles primarily include acquired software licenses and third party software in development, which are recorded at cost and

amortized over the estimated useful lives of approximately three years.

Intangibles are assessed for impairment whenever events or changes in circumstances indicate that an asset’s carrying amount may

not be recoverable.

(m)

Leases prior to the adoption of ASC 842 on January 1, 2019

Costs in respect of operating leases in the year ended December 31, 2018 prior to the adoption of ASC 842 were charged to the 
Consolidated Statement of Operations on a straight-line basis over the lease term.  Rent holidays were recognized on a straight-line basis 
over the lease term (including any rent holiday period).  Lease incentives, including leasehold improvement incentives or allowances, were 
recorded as deferred rent and amortized as reductions to lease expense over the lease term.  Leasehold improvements made by a lessee that 
were funded by landlord incentives or allowances were recorded as leasehold improvement assets and amortized over the shorter of the 
useful life of the asset and the non-cancellable lease term. 

Lease expenses amounted to $3,399,000 for the year ended December 31, 2018. These were recorded within research and

development and general and administrative expenses in the Company’s Consolidated Statements of Operations.

(n)

Leases after the adoption of ASC 842 on January 1, 2019

On January 1, 2019, the Company adopted a new standard, Accounting Standard Update 2016-02 – Leases, which is codified in

ASC 842. The comparative financial information for the year ended December 31, 2018 has not been restated and is prepared in accordance
with the accounting policies that are described in Note 2 to the Consolidated Financial Statements included in the Annual Report.

F-17

 
Table of Contents

The Company determines whether an arrangement is a lease at contract inception by establishing if the contract conveys the right

to use, or control the use of, identified property, plant, or equipment for a period of time in exchange for consideration. Leases may be
classified as finance leases or operating leases. All the Company’s leases are classified as operating leases as they were previously classed
as these and the lease classification is not reassessed on adoption of ASC 842. Operating lease right-of-use (ROU) assets and operating
lease liabilities recognized in the Consolidated Balance Sheet represent the right to use an underlying asset for the lease term and an
obligation to make lease payments arising from the lease respectively.

Operating lease ROU assets and operating lease liabilities are recognized at the lease commencement date based on the present

value of minimum lease payments over the lease term. Since the rate implicit in the lease is not readily determinable, the Company uses its
incremental borrowing rates (the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term
for an amount equal to the lease payments in a similar economic environment) based on the information available at commencement date in
determining the discount rate used to calculate the present value of lease payments. As the Company has no external borrowings, the
incremental borrowing rates are determined using information on indicative borrowing rates that would be available to the Company based
on the value, currency and borrowing term provided by financial institutions, adjusted for company and market specific factors. The lease
term is based on the non-cancellable period in the lease contract, and options to extend the lease are included when it is reasonably certain
that the Company will exercise that option. Any termination fees are included in the calculation of the ROU asset and lease liability when it
is assumed that the lease will be terminated.

The Company accounts for lease components (e.g. fixed payments including rent and termination costs) separately from non-lease
components (e.g. common-area maintenance costs and service charges based on utilization) which are recognized over the period in which
the obligation occurs.

At each reporting date, the operating lease liabilities are increased by interest and reduced by repayments made under the lease

agreements.

The right-of-use asset is subsequently measured for an operating lease at the amount of the remeasured lease liability (i.e. the

present value of the remaining lease payments), adjusted for the remaining balance of any lease incentives received, any cumulative prepaid
or accrued rent if the lease payments are uneven throughout the lease term, and any unamortized initial direct costs.

The Company has operating leases in relation to property for office and research facilities. All of the leases have termination

options, and it is assumed that the initial termination options for the buildings will be activated for most of these. The maximum lease term
without activation of termination options is to 2041.

In May 2017, the Company entered into an agreement for the lease of a building at Milton Park, Oxfordshire, United Kingdom.  

The term of the lease expires on October 23, 2041, with termination options exercisable by the Company on the fifth anniversary of the 
lease commencement date and at approximately five yearly intervals thereafter.

In September 2015, the Company entered into an agreement for a 25- year lease, with early termination options, for a research and 

development facility in Oxfordshire, United Kingdom.  In October 2016, the Company entered into the lease for that facility following the 
completion of construction. 

In July 2015, the Company entered into a 15 year lease agreement, with an early termination option at 123 months, for offices and 

research facilities in Philadelphia, United States.  The lease commenced upon completion of construction in October 2016.

The Company has elected not to recognize a right-of-use asset and lease liability for short-term leases. A short-term lease is a

lease with a lease term of 12 months or less and which does not include an option to purchase the underlying asset that the lessee is
reasonably certain to exercise.

Operating lease costs are recognized on a straight-line basis over the lease term, and they are categorized within Research and

development and General and administrative expenses in the Consolidated Statement of Operations. The

F-18

Table of Contents

operating lease cash flows are categorized under Net cash used in operating activities in the Consolidated Statement of Cash Flows.

(o)         Segmental reporting

Operating segments are identified as components of an enterprise about which separate discrete financial information is available

for evaluation by the chief operating decision-maker in making decisions regarding resource allocation and assessing performance. The
Company’s chief operating decision maker (the “CODM”), its Chief Executive Officer, manages the Company’s operations on an
integrated basis for the purposes of allocating resources. When evaluating the Company’s financial performance, the CODM reviews total
revenues, total expenses and expenses by function and the CODM makes decisions using this information on a global basis. Accordingly,
the Company has determined that it operates in one operating segment.

(p)          Revenue

On January 1, 2018, the Company adopted new guidance on revenue recognition, which has been codified within ASC 606.  

During the year ended December 31, 2019, the Company had one contract with a customer, which is the GSK Collaboration and License 
Agreement.  The GSK Collaboration and License Agreement consists of multiple performance obligations, including the transition of the 
NY-ESO SPEAR T-cell program to GSK, the development of a second and third target, and an exclusive license (the “NY-ESO License”) 
to research, develop, and commercialize the Company’s NY-ESO SPEAR T-cell therapy program.

In September 2017, GSK exercised its option to obtain the NY-ESO License and a detailed transition plan followed, identifying 
the steps needed to complete transition of the Investigational New Drug (IND) process with the Food and Drug Administration (FDA) for 
the NY-ESO SPEAR T-cell program to GSK.  On July 23, 2018, the transition activities were substantially completed and the IND for the 
NY-ESO SPEAR T-cell program transferred to GSK.

GSK nominated a second target program for the PRAME target antigen, which was announced on 9 January 2017. The Company
completed all work under this collaboration program in 2018. The program led to the development of a final lead candidate SPEAR T-cell
directed to a specific peptide from the PRAME antigen. GSK and Adaptimmune agreed that the collaboration should not continue due to
the peptide, to which the lead candidate was directed, not reaching GSK criteria.

In 2019, GSK has nominated its third target under the Collaboration and License Agreement. Development of products to this

target commenced in the year ended December 31, 2019, and the Company received $3.2 million following the nomination of the target.
The development of products to the third target is a separate performance obligation. Revenue allocated to this performance obligation is
expected to be recognized by the end of 2020 as the development progresses. Future revenues will depend on the progress of the
development programs within the Collaboration and License Agreement, and GSK’s progress with the NY-ESO program, which are
difficult to predict.

There was no variable consideration at December 31, 2019. The Company determines the variable consideration to be included in
the transaction price by estimating the most likely amount that will be received and then applies a constraint to reduce the consideration to
the amount which is probable of being received. The determination of whether a milestone is probable includes consideration of the
following factors:

● whether achievement of a development milestone is highly susceptible to factors outside the entity’s influence, such as milestones

involving the judgment or actions of third parties, including regulatory bodies or the customer;

● whether the uncertainty about the achievement of the milestone is not expected to be resolved for a long period of

time;

● whether the Company can reasonably predict that a milestone will be achieved based on previous experience;

and.

F-19

Table of Contents

●

the complexity and inherent uncertainty underlying the achievement of the
milestone.

Under the terms of the GSK Collaboration and License Agreement, the Company may also be entitled to development milestones.  
The development and regulatory milestones are per product milestones and are dependent on achievement of certain obligations, the nature 
of the product being developed, stage of development of product, territory in which an obligation is achieved and type of indication or 
indications in relation to which the product is being developed. In addition, for any program multiple products may be developed to address 
different HLA-types.  These amounts have not been included within the transaction price as of December 31, 2019 because they are not 
considered probable. 

The Company may also receive commercialization milestones upon the first commercial sale of a product based on the indication

and the territory and mid-single to low double-digit royalties on worldwide net sales. These amounts have not been included within the
transaction price as of December 31, 2019 because they are sales or usage-based royalties promised in exchange for a license of intellectual
property, which will be recognized when the subsequent sale or usage occurs.

The payments to the Company under the contract are typically due upon achievement of milestones and within standard payment 

terms (approximating to 45 days).  The contract does not include a significant financing component.

The amount of the transaction price allocated to the performance obligation is recognized as or when the Company satisfies the 

performance obligation.  The Company satisfies the performance obligations relating to the development of each target over time and 
recognizes revenue based on an estimate of the percentage of completion of the project determined based on the costs incurred on the 
project as a percentage of the total expected costs.  The Company considers that this depicts the progress of the project, where the 
significant inputs are internal project resource and third-party clinical and manufacturing costs.  The determination of the percentage of 
completion requires the Company to estimate the costs-to-complete the project.  The Company makes a detailed estimate of the costs-to-
complete on an annual basis as part of the Company’s budgeting process, which is re-assessed every reporting period based on the latest 
project plan and discussions with project teams.  If a change in facts or circumstances occurs, the estimate is adjusted and the revenue is 
recognized based on the revised estimate. The difference between the cumulative revenue recognized based on the previous estimate and 
the revenue recognized based on the revised estimate is recognized as an adjustment to revenue in the period in which the change in 
estimate occurs.

The previous performance obligation relating to the NY-ESO License was recognized at a point-in-time, upon commencement of

the license in 2018.

The Company recognizes a contract asset, when the value of satisfied (or part satisfied) performance obligations is in excess of the 

payment due to the Company, and deferred revenue (contract liability) when the amount of unconditional consideration is in excess of the 
value of satisfied (or part satisfied) performance obligations.  Once a right to receive consideration is unconditional, that amount is 
presented as a receivable.

Changes in deferred revenue typically arise due to:

●

●

●

●

adjustments arising from a change in the estimate of the cost to complete the project, which results in a cumulative catch-
up adjustment to revenue that affects the corresponding contract asset or deferred revenue;

a change in the estimate of the transaction price due to changes in the assessment of whether variable consideration is
constrained because it is not considered probable of being received;

the recognition of revenue arising from deferred revenue;
and

the reclassification of amounts to receivables when a right to consideration to becomes
unconditional.

F-20

Table of Contents

A change in the estimate of variable consideration constrained (for example, if a development milestone becomes probable of

being received) could result in a significant change in the revenue recognized and deferred revenue.

Revenue is recognized when earned and realized or realizable, which is generally when persuasive evidence of an arrangement
exists, delivery has occurred or services have been rendered, the seller’s price to the buyer is fixed or determinable, and collectability is
reasonably assured. Where applicable, all revenues are stated net of value added and similar taxes.

(q)          Research and development expenditures

Research and development expenditures are expensed as incurred.

Expenses related to clinical trials are recognized as services are received. Nonrefundable advance payments for services are 
deferred and recognized in the Consolidated Statement of Operations as the services are rendered.  This determination is based on an 
estimate of the services received and there may be instances when the payments to vendors exceed the level of services provided resulting in 
a prepayment of the clinical expense. If the actual timing of the performance of services varies from our estimate, the accrual or prepaid 
expense is adjusted accordingly.

Upfront and milestone payments to third parties for in-licensed products or technology which has not yet received regulatory

approval and which does not have alternative future use in R&D projects or otherwise are expensed as incurred. The Company expensed
acquired in-process R&D of $4,556,000, and $210,000 in the years ended December 31, 2019 and 2018, respectively.

Milestone payments made to third parties either on or subsequent to regulatory approval are capitalized as an intangible asset and

amortized over the remaining useful life of the product.

Research and development expenditure is presented net of R&D tax and expenditure credits from the U.K. government, which are
recognized over the period necessary to match the reimbursement with the related costs when it is probable that the Company has complied
with any conditions attached and will receive the reimbursement. Reimbursable R&D tax and expenditure credits were $18,649,000 and
$17,299,000 in the years ended December 31, 2019 and 2018, respectively.

(r)          Share-based compensation

The Company awards certain employees and non-employees options over the ordinary shares of the parent company.  The cost of 

share-based awards issued to employees are measured at the grant-date fair value of the award and recognized as an expense over the 
requisite service period.  The fair value of the options is determined using the Black-Scholes option-pricing model.  Share options with 
graded-vesting schedules are recognized on a straight-line basis over the requisite service period for each separately vesting portion of the 
award.  The Company has elected to account for forfeitures of stock options when they occur by reversing compensation cost previously 
recognized, in the period the award is forfeited, for an award that is forfeited before completion of the requisite service period.

(s)          Retirement benefits

The Company operates defined contribution pension schemes for its directors and employees. The contributions to this scheme are 

expensed to the Consolidated Statement of Operations as they fall due.  The pension contributions for the years ended December 31, 2019 
and 2018 were $1,904,000 and $1,847,000, respectively.

(t)          Income taxes

Income taxes for the period comprise current and deferred tax.  Income tax is recognized in the Consolidated Statement of 
Operations except to the extent that it relates to items occurring during the year recognized either in other comprehensive income or directly 
in equity, in which case it is recognized in other comprehensive income or equity.

F-21

Table of Contents

Current tax is the expected tax payable or receivable on the taxable income or loss for the current or prior periods using tax rates

enacted at the balance sheet date.

Deferred tax is accounted for using the asset and liability method that requires the recognition of deferred tax assets and liabilities

for the expected future tax consequences of temporary differences between the financial statement carrying amount and the tax bases of
assets and liabilities at the applicable tax rates and for operating loss and tax credit carryforwards. A valuation allowance is provided when
it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company evaluates the realizability of
its deferred tax assets by assessing its valuation allowance and by adjusting the amount of such allowance, if necessary. The factors used to
assess the likelihood of realization include the Company’s forecast of income, carryback availability, reversing taxable temporary
differences and available tax-planning strategies that could be implemented to realize the deferred tax assets.

Income tax positions must meet a more-likely-than-not recognition threshold to be recognized. Income tax positions that 
previously failed to meet the more-likely-than-not threshold are recognized in the first subsequent financial reporting period in which that 
threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not threshold are derecognized in the first 
subsequent financial reporting period in which that threshold is no longer met. Recognized income tax positions are measured at the largest 
amount that is greater than 50 percent likely of being realized.  We recognize potential accrued interest and penalties related to 
unrecognized tax benefits within the Consolidated Statement of Operations as income tax expense.

In interim periods, the income tax expense (benefit) related to income (loss) from continuing operations before income tax

expense (benefit) excluding significant unusual or infrequently occurring items is computed at an estimated annual effective tax rate and
the income tax expense (benefit) related to all other items is individually computed and recognized when the items occur.

(u)          Loss per share

Basic loss per share is determined by dividing net loss attributable to ordinary shareholders by the weighted average number of 

ordinary shares outstanding during the period.  Diluted loss per share is determined by dividing net loss attributable to ordinary shareholders 
by the weighted average number of ordinary shares outstanding during the period, adjusted for the dilutive effect of all potential ordinary 
shares that were outstanding during the period.  Potentially dilutive shares are excluded when the effect would be to increase diluted 
earnings per share or reduce diluted loss per share.

The following table reconciles the numerator and denominator in the basic and diluted loss per share computation (in thousands):

(v)          New accounting pronouncements

Adopted in the year ended December 31, 2019

Leases

On January 1, 2019, the Company adopted Accounting Standard Update 2016-02 – Leases, which is codified in ASC 842. The

Company has adopted the guidance using the modified retrospective approach, with the cumulative effect of initially applying the guidance
recognized as an adjustment to the opening balance of equity at January 1, 2019. Therefore, the comparative information has not been
adjusted and continues to be reported under previous guidance. The Company elected the package of practical expedients permitted under
the transition guidance within the new standard, which among other things, allowed it to carry forward the historical lease classification of
the Company’s leases as operating leases. The effect on the accumulated deficit, total stockholders’ equity and net assets as at January 1,
2019 was $0.

The adoption of ASC 842 has had a material impact on the Company’s financial statements. At January 1, 2019 the Company

recognized right-of-use assets and liabilities for operating leases following the adoption date of $22.2 million and $26.9 million
respectively and derecognized $4.7 million of other liabilities and prepayments that had been recognized under previous guidance.

To be adopted in future periods

Measurement of Credit Losses on Financial Instruments

In June 2016, the FASB issued ASU 2016-13 - Financial Instruments - Credit losses, which replaces the incurred loss impairment
methodology for financial instruments in current GAAP with a methodology that reflects expected credit losses and requires consideration
of a broader range of reasonable and supportable information to inform credit loss estimates. The guidance is effective for the fiscal year
beginning January 1, 2020, including interim periods within that fiscal year. The FASB has issued ASU 2019-10 which has resulted in the
postponement of the effective date of the new guidance for eligible smaller reporting companies to the fiscal year beginning January 1,
2023. The Company currently intends to adopt the guidance in the fiscal year beginning January 1, 2023. The guidance must be adopted
using a modified-retrospective approach and a prospective transition approach is required for debt securities for which an other-than-
temporary impairment had been recognized before the effective date. The Company is currently evaluating the impact of the guidance on its
Consolidated Financial Statements.

Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract

In August 2018, the FASB issued ASU 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, which aligns the
requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for
capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use
software license). The guidance is effective for the fiscal year beginning January 1, 2020, including interim periods within that fiscal year.
The guidance may be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The
Company does not expect the impact of the guidance to have a material impact on the Consolidated Financial Statements.

Changes to the Disclosure Requirements for Fair Value Measurement

In August 2018, the FASB issued ASU 2018-13 — Fair Value Measurement (Topic 820) - Disclosure Framework— Changes to 

the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements on fair value measurements in Topic 
820, Fair Value Measurement.  The guidance is effective for the fiscal year beginning January 1, 2020, including interim periods within that 
fiscal year. Certain amendments apply prospectively with the all other amendments applied retrospectively to all periods presented upon 
their effective date. The Company does not expect the impact of the guidance to have a material impact on the Consolidated Financial 
Statements.

Revenue Recognition in Collaborative Arrangements

In November 2018, the FASB issued ASU 2018-18 – Collaborative Arrangements — Clarifying the Interaction between Topic

808 and Topic 606, which clarifies that certain transactions between collaborative arrangement participants should be accounted for as
revenue under Topic 606 when the collaborative arrangement participant is a customer in the context of a unit of account. In those
situations, all the guidance in Topic 606 should be applied, including recognition, measurement, presentation, and disclosure requirements.
The Company will adopt the guidance from Jan 1, 2020 and is still assessing the impact on its collaboration deals but does not expect it to
be material.

Table of Contents

The Company estimates the fair value of available-for-sale debt securities with the aid of a third party valuation service, which 
uses actual trade and indicative prices sourced from third-party providers on a daily basis to estimate the fair value.  If observed market 
prices are not available (for example securities with short maturities and infrequent secondary market trades), the securities are priced using 
a valuation model maximizing observable inputs, including market interest rates.

Significant concentration of credit risk

The Company held cash and cash equivalents of $50,412,000, marketable securities of $39,130,000 and restricted cash of

$4,496,000 as of December 31, 2019. The cash and cash equivalents and restricted cash are held with multiple banks and the Company
monitors the credit rating of those banks. The Company maintains cash balances in excess of amounts insured by the Federal Deposit
Insurance Corporation in the United States and the U.K. Government Financial Services Compensation Scheme in the United Kingdom.

The Company has one customer as a result of the GSK Collaboration and License Agreement. There were no trade receivables as

of December 31, 2019 and $192,000 as of December 31, 2018. Trade receivables arise in relation to the GSK Collaboration and License
Agreement. The Company has been transacting with GSK since June 2014, during which time no impairment losses have been recognized.
As of December 31, 2019, there were no overdue accounts receivable.

Foreign exchange risk

The Company is exposed to foreign exchange rate risk because it operates in the United Kingdom and the United States.  The 

Company’s revenue from the GSK Collaboration and License Agreement is denominated in pounds sterling and is generated by our U.K.-
based subsidiary, which has a pounds sterling functional currency. As a result, these sales are subject to translation into U.S. Dollars when 
the financial statements are consolidated. Expenses are generally denominated in the currency in which the Company’s operations are 
located, which are the United Kingdom and the United States. However, the U.K.-based subsidiary incurs significant research and 
development costs in U.S. dollars and, to a lesser extent, Euros.

The results of operations and cash flows will be subject to fluctuations due to changes in foreign currency exchange rates, which
could harm the Company’s business in the future. Management seeks to minimize this exposure by maintaining currency cash balances at
levels appropriate to meet foreseeable expenses in U.S. dollars and pounds sterling. To date, the Company has not used forward exchange
contracts or other currency hedging products to manage exchange rate exposure, although it may do so in the future. The exchange rate as
of December 31, 2019, the last business day of the reporting period, was £1.00 to $1.31.

Interest Rate Risk

Surplus cash and cash equivalents are invested in interest-bearing savings, money market funds, corporate debt securities and 

commercial paper from time to time.  Investments in corporate debt securities are subject to fixed interest rates.  The Company’s exposure to 
interest rate sensitivity is impacted by changes in the underlying U.K. and U.S. bank interest rates and the fair market value of its corporate 
debt securities will fall in value if market interest rates increase. Management believes that an immediate one percentage point change in 
interest rates would not have a material effect on the fair market value of our portfolio, and therefore does not expect the operating results or 
cash flows to be significantly affected by changes in market interest rates.

In 2016, the Company entered into a supply agreement with ThermoFisher for the supply of the Dynabeads® CD3/CD28

technology. The supply agreement runs until December 31, 2025. Under the supply agreement, the Company is required to purchase its
requirements for CD3/CD28 magnetic bead product exclusively from ThermoFisher for a period of 5 years. There are minimum purchasing
obligations of $5.0 million, $2.5 million of which is payable in 2020 and $2.5 million of which is payable in 2021. Management regularly
updates the assessment of the utility of the Dynabeads, and in the year ended December 31, 2019, considered that there is sufficient
uncertainty surrounding the utility of the Dynabeads, which is dependent upon current study trajectories, the Company’s clinical pipeline,
manufacturing methods and undetermined future projects, to result in the $5.0 million purchase commitment being recognized in Research

Commitments for clinical materials, clinical trials and contract manufacturing

As of December 31, 2019, the Company had non-cancellable commitments for purchase of clinical materials, contract

manufacturing, maintenance, and committed funding under the MD Anderson strategic alliance of up to $13,657,000, of which the
Company expects to pay $6,552,000 within one year and $7,105,000 in one to three years. The amount and timing of these payments vary
depending on the rate of progress of development. Future clinical trial expenses have not been included within the purchase commitments
because they are contingent on enrollment in clinical trials and the activities required to be performed by the clinical sites. The Company’s
subcontracted costs for clinical trials and contract manufacturing were $32,788,000 and $41,580,000 for the years ended December 31,
2019 and 2018, respectively.

In addition to the above commitments, the company has recognized commitments for the purchase of clinical materials of

$5,000,000 in the year ended December 31, 2019, $2,500,000 of which the Company expects to pay within one year, and $2,500,000 of
which the Company expects to pay in one to three years. Further details of these commitments are provided in Note 9.

Bellicum Pharmaceuticals Inc., Co-Development and Co-Commercialization Agreement

On December 16, 2016, the Company entered into a Co-Development and Co-Commercialization Agreement with Bellicum

Pharmaceuticals, Inc. (“Bellicum”) in order to facilitate a staged collaboration to evaluate, develop and commercialize next generation T-
cell therapies.

Under the agreement, the Company will evaluate Bellicum’s GoTCR technology (inducible MyD88/CD40 co-stimulation, or iMC) 

with the Company’s SPEAR T-cells for the potential to create enhanced T-cell therapeutics. Depending on results of the initial preclinical 
proof-of-concept phase, the agreement may progress to a two-target co-development and co-commercialization phase. To the extent 
necessary, and in furtherance of the parties’ proof-of-concept and co-development efforts, the parties granted each other a royalty-free, non-
transferable, non-exclusive license covering their respective technologies for purposes of facilitating such proof-of-concept and co-
development efforts. In addition, as to covered therapies developed under the agreement, the parties granted each other a reciprocal 
exclusive license for the commercialization of such therapies.  During the proof of concept phase, each party bears its own costs and there 
are no payments made between the Company and Bellicum.  Any research and development costs incurred by the Company with third 
parties have been accounted for in accordance with the Company’s accounting policy for research and development expenses.

With respect to any joint commercialization of a covered therapy, the parties agreed to negotiate in good faith the commercially

reasonable terms of a co-commercialization agreement. The parties also agreed that any such agreement shall provide for, among other
things, equal sharing of the costs of any such joint commercialization and the calculation of profit shares as set forth in the agreement.

The agreement will expire on a country-by-country basis once the parties cease commercialization of the T-cell therapies covered

by the agreement, unless earlier terminated by either party for material breach, non-performance or cessation of development,
bankruptcy/insolvency, or failure to progress to co-development phase.

MD Anderson Strategic Alliance

On September 26, 2016, the Company announced that it had entered into a multi-year strategic alliance with The University of

Texas MD Anderson Cancer Center (“MD Anderson”) designed to expedite the development of T-cell therapies for multiple types of
cancer. The Company and MD Anderson are collaborating on a number of studies including clinical and preclinical development of the
Company’s SPEAR T-cell therapies targeting NY-ESO, MAGE-A10 and MAGE-A4 and will collaborate on future clinical stage first and
second generation SPEAR T-cell therapies across a number of cancers.

Under the terms of the agreement, the Company committed at least $19,644,000 to fund studies. Payment of this funding is

contingent on mutual agreement to study orders in order for any study to be included under the alliance

F-30

Table of Contents

and the performance of set milestones by MD Anderson. The Company made an upfront payment of $3,412,000 to MD Anderson in the
year ended December 31, 2017 and milestone payments of $2,325,000 in the year ended December 31, 2018.  The Company is obligated to 
make further payments to MD Anderson as certain milestones are achieved. These costs are expensed to research and development as MD 
Anderson renders the services under the strategic alliance.

The agreement may be terminated by either party for material breach by the other party. Individual studies may be terminated for,

amongst other things, material breach, health and safety concerns or where the institutional review board, the review board at the clinical
site with oversight of the clinical study, requests termination of any study. Where any legal or regulatory authorization is finally withdrawn
or terminated, the relevant study will also terminate automatically.

Universal Cells Research, Collaboration and License Agreement and Co-development and Co-commercialization agreement

On November 25, 2015, the Company entered into a Research, Collaboration and License Agreement relating to gene editing and Human
Leukocyte Antigen (“HLA”) engineering technology with Universal Cells, Inc. (“Universal Cells”). The Company paid an upfront license
and start-up fee of $2.5 million to Universal Cells in November 2015, a milestone payment of $3.0 million in February 2016 and further
milestone payments of $0.2 million and $0.9 million were made in the year ended December 31, 2018 and 2017, respectively. The
agreement was amended and re-stated as at January 13, 2020, primarily to reflect changes to the development plan agreed between the
parties. Further milestone payments of up to $38.4 million are payable if certain development and product milestones are achieved.
Universal Cells would also receive a profit-share payment for the first product, and royalties on sales of other products utilizing its
technology. The upfront license and start-up fee and milestone payments were expensed to research and development when incurred.

Noile-Immune Collaboration Agreement

On August 26, 2019, the Company entered into a collaboration and license agreement relating to the development of next-

generation SPEAR T-cell products with Noile-Immune Biotech Inc. (“Noile-Immune”). An upfront exclusive license option fee of $2.5
million was paid to Noile-Immune in 2019. This has been recognized within Research and Development in the Consolidated Statement of
Operations for the year ended December 31, 2019. Under the agreement, development and commercialization milestone payments up to a
maximum of $312 million may be payable if all possible targets are selected and milestones achieved. Noile-Immune would also receive
mid-single-digit royalties on net sales of resulting products.

Alpine Collaboration Agreement

On May 14, 2019, the Company entered into a Collaboration Agreement relating to the development of next-generation SPEAR

T-cell products with Alpine Immune Sciences Inc. (“Alpine”). The Company paid an upfront exclusive license option fee of $2.0 million to
Alpine in June 2019. Under the agreement, Adaptimmune will pay Alpine for ongoing research and development funding costs and
development and commercialization milestone payments up to a maximum of $288 million may be payable if all possible targets are
selected and milestones achieved. The upfront payment of $2.0 million and the payments for ongoing research are recognized within
Research and development. Alpine would also receive low single-digit royalties on worldwide net sales of applicable products.

ThermoFisher License Agreement

In 2012, the Company entered into a series of license and sub-license agreements with Life Technologies Corporation, part of

ThermoFisher Scientific, Inc. (“ThermoFisher”) that provide the Company with a field-based exclusive license under certain intellectual
property rights owned or controlled by ThermoFisher.  The Company paid upfront license fees of $1.0 million relating to the license and
sublicense agreements and has an obligation to pay minimum annual royalties (in the tens of thousands of U.S. dollars prior to licensed
product approval and thereafter at a level of 50% of running royalties in the previous year), milestone payments and a low single-digit
running royalty payable on the net selling price of each licensed product. The upfront payment made in 2012 was expensed to research and
development when incurred. Subsequent milestone payments have been recognized as an intangible asset due to the

In 2016, the Company entered into a supply agreement with ThermoFisher for the supply of the Dynabeads® CD3/CD28

technology. The Dynabeads® CD3/CD28 technology is designed to isolate, activate and expand human T-cells, and is being used in the
manufacturing of the Company’s affinity enhanced T-cell therapies.  The supply agreement runs until December 31, 2025. Under the
supply agreement the Company is required to purchase its requirements for CD3/CD28 magnetic bead product from ThermoFisher for a
period of 5 years and there are also minimum purchasing obligations. $5.0 million of these purchase commitments have been recognized in
research and development expense in the year ended December 31, 2019. $2.5 million of the purchase commitments are payable in 2020
and $2.5 million are payable in 2021. ThermoFisher has the right to terminate the supply agreement for material breach or insolvency.

Adaptimmune Therapeutics plc Employee Share Option Scheme (adopted on January 14, 2016), (ii) the Adaptimmune Therapeutics plc
2015 Share Option Scheme (adopted on March 16, 2015) and (iii) the Adaptimmune Therapeutics plc Company Share Option Plan
(adopted on March 16, 2015).

Table of Contents

The Adaptimmune Therapeutics plc Company Share Option Plan is a tax efficient option scheme intended to comply with the

requirements of Schedule 4 to the Income Tax (Earnings and Pensions) Act 2003 of the United Kingdom, which provides for the grant of
company share option plan (“CSOP”) options. Grants may not exceed the maximum value of £30,000 per participant for the shares under
the option, which is a CSOP compliance requirement.

Generally, the vesting dates for the options granted under these plans up to December 31, 2019 are 25% on the first anniversary of

the grant date and 75% in monthly installments over the following three years. However, the options granted to non-executive directors
under the Adaptimmune Therapeutics plc 2015 Share Option Scheme vest and become exercisable as follows:

Options granted to non-executive directors on May 11, 2015:
Options granted to a non-executive director on June 23, 2016:

Options granted to non-executive directors on August 11, 2016:
Options granted to non-executive directors on November 28, 2016:

Effective from January 2018, the Company has also granted restricted stock unit style options (“RSU-style”). The RSU-style
options over ordinary shares in Adaptimmune Therapeutics plc are granted under the Adaptimmune Therapeutics plc Employee Share
Option Scheme (adopted on January 14, 2016).  These options have an exercise price equal to the nominal value of an ordinary share, of
£0.001, and generally vest over four years, with 25% on the first, and each subsequent, anniversary of the grant date.  

Options granted under these plans are not subject to performance conditions. The contractual term of options granted under these

plans is ten years.

The maximum aggregate number of options which may be granted under these plans and any incentive plans adopted by the

Company cannot exceed a scheme limit that equates to 8% of the initial fully diluted share capital of the Company immediately following
its IPO plus an automatic annual increase of an amount equivalent to 4% of the issued share capital on each 30 June (or such lower number
as the Board, or an appropriate committee of the Board, may determine). The automatic increase is effective from July 1, 2016.

Prior to December 31, 2014, the Company granted options to purchase ordinary shares in Adaptimmune Limited under three

option schemes:

(i)   The Adaptimmune Limited Share Option Scheme was adopted on May 30, 2008.  Under this scheme Enterprise Management 

Incentive (“EMI”) options (which are potentially tax-advantaged in the United Kingdom) have been granted (subject to the relevant 
conditions being met) to its employees who are eligible to receive EMI options under applicable U.K. tax law and unapproved options 
(which do not attract tax advantages) have been granted to its employees who are not eligible to receive EMI options, and to its Directors 
and consultants. In May 2014, the Company no longer qualified for EMI status and since that date, no further EMI options were granted 
under this scheme; however, unapproved options have been under granted under this scheme since that date.

(ii)  The Adaptimmune Limited 2014 Share Option Scheme was adopted on April 11, 2014. EMI options were granted (subject to

the relevant conditions being met) under this scheme to our employees who are eligible to receive

F-33

Table of Contents

EMI options under applicable U.K. tax law. Unapproved options were granted to its employees who are not eligible to receive EMI options 
and to directors.  In May 2014, the Company no longer qualified for EMI status and since that date, no further EMI options were granted 
under this scheme; however, unapproved options have been under granted under this scheme since that date.

(iii) The Adaptimmune Limited Company Share Option Plan was adopted on December 16, 2014. This scheme allowed the grant
of options to our eligible employees prior to the Company’s corporate reorganization in 2015. This scheme is a tax efficient option scheme
and options were granted on December 19, 2014 and on December 31, 2014 to our part-time and full-time employees.

As part of the corporate reorganization in connection with our IPO, the holders of options granted under these schemes over

ordinary shares of Adaptimmune Limited were granted equivalent options on substantially the same terms over ordinary shares of
Adaptimmune Therapeutics plc (“Replacement Options”) in exchange for the release of these options. The Company does not intend to
grant any further options under these schemes.

Generally, the vesting dates for the Replacement Options under the Adaptimmune Limited schemes are:

Options granted in 2009:
Options granted in 2011, 2012, 2013

and April 2014:

Options granted in December 2014:  

100% on the third anniversary of the grant date
25% on the first anniversary of the grant date and 75% in annual installments
over the following three years
25% on the first anniversary of the grant date and 75% in monthly installments
over the following three years

The contractual life of options granted under these schemes is ten years.

The valuation allowances are primarily related to deferred tax assets for operating loss and tax credit carry-forwards and 

temporary differences relating to share-based compensation expense.  Deferred tax assets have been recognized without a valuation 
allowance to the extent supported by reversing taxable temporary differences.  A valuation allowance has been provided over the remaining 
deferred tax assets, which management considered are not more likely than not of being realized after weighing all available positive and 
negative evidence including cumulative losses in recent years and projections of future taxable losses.

The Company is headquartered in the United Kingdom and has subsidiaries in the United Kingdom and the United States. The 

Company incurs tax losses in the United Kingdom.  The weighted-average U.K. corporate tax rate for the years ended December 31, 2019 
and 2018 was 19% in both years. The Company’s subsidiary in the United States has generated taxable profits due to a service agreement
between the Company’s subsidiaries in the United States and the United Kingdom. The U.S. federal corporate tax rate was 21% for the
years ended December 31, 2019 and 2018, respectively.

The United Kingdom’s 2016 Finance Bill, which was enacted on September 15, 2016, contained reductions in corporation tax to

19% from April 1, 2017 and 17% from April 1, 2020. The Company used a 17% tax rate as of December 31, 2019 in respect of the
measurement of deferred taxes arising in the United Kingdom, which reflects the currently enacted tax rate and the anticipated timing of the
unwinding of the deferred tax balances. In respect of the measurement of deferred taxes arising in the U.S, the Company has adopted a 21% 
tax rate as of December 31, 2019.  

As of December 31, 2019, we do not have unremitted earnings in our U.S. subsidiary.

As of December 31, 2019, we had U.K. net operating losses of approximately $249.8 million, expenditure credit carryforwards of

$0.7 million and U.S. tax credit carryforwards of $5.7 million. Unsurrendered U.K. tax losses and tax credit carryforwards can be carried
forward indefinitely to be offset against future taxable profits, however this is restricted to an annual £5 million allowance in each
standalone company or group and above this allowance, there will be a 50% restriction in the profits that can be covered by losses brought
forward. U.S. tax credit carryforwards can be carried forward for 20 years.  The tax credit carryforwards expire between 2036 and 2039.

Our tax returns are under routine examination in the U.K. and U.S. tax jurisdictions. The scope of these examinations includes, but 

is not limited to, the review of our taxable presence in a jurisdiction, our deduction of certain items, our claims for research and 
development credits, our compliance with transfer pricing rules and regulations and the inclusion or exclusion of amounts from our tax 
returns as filed.  The Company is no longer subject to examinations 

F-38

    
    
    
    
Table of Contents

by tax authorities for the tax years 2012 and prior in the United Kingdom.  However, U.K. net operating losses from the tax years 2012 and 
prior would be subject to examination if and when used in a future tax return to offset taxable income. Our U.K. income tax returns have 
been accepted by Her Majesty’s Revenue and Customs through the period ended December 31, 2016. The Company is subject to 
examinations by tax authorities in the United States for all tax years 2013 through 2019. Our U.S. federal income tax return for the year 
ended June 30, 2014 was audited by the U.S. Internal Revenue Service and resulted in no changes and our U.S. federal income tax return for 
the year ended December 31, 2016 is being audited by the U.S. Internal Revenue Service. We are also subject to audits by U.S. state taxing 
authorities where we have operations.

Unrecognized tax benefits arise when the estimated benefit recorded in the financial statements differs from the amounts taken or

expected to be taken in a tax return because of the uncertainties described above. As of December 31, 2019 and December 31, 2018, the
Company had no unrecognized tax benefits.

Note 15 — Subsequent events

On January 13, 2020, the Company entered into a co-development and co-commercialization agreement with Astellas Pharma,

Inc. (the “Astellas Collaboration Agreement”). The Company received an upfront payment of $50.0 million in January 2020 under the
agreement and will receive research funding of up to $7.5 million per year from the start of research programs under the agreement.
Additional milestones are possible under the agreement, but these are dependent on the success of the development and commercialization
of research and products.

On January 24, 2020, the Company closed an underwritten public offering of 21,000,000 American Depository Shares (ADSs)

which, together with the full exercise by the underwriters on February 7, 2020 of their option to purchase an additional 3,150,000 ADSs,
generated net proceeds of approximately $89.8 million.

no preferred shares outstanding. All ordinary shares have the same rights and rank pari passu in all respects. Subject to the provisions of the Companies Act
2006 and any other relevant legislation, our shares may be issued with such preferred, deferred or other rights, or such restrictions, whether in relation to
dividends, returns of capital, voting or otherwise, as we may determine by ordinary resolution (or, failing any such determination, as the directors may
determine).

Ordinary Shares

Voting Rights

Subject to any other provisions of our articles of association and without prejudice to any special rights, privileges or restrictions as to voting attached
to any shares forming part of our share capital, the voting rights of shareholders are as follows. On a show of hands, each shareholder present in person, and
each duly authorized representative present in person of a shareholder that is corporation, has one vote. On a show of hands, each proxy present in person
who has been duly appointed by one or more shareholders has one vote, but a proxy has one vote for and one vote against a resolution if, in certain
circumstances, the proxy is instructed by more than one shareholder to vote in different ways on a resolution. On a poll, each shareholder present in person
or by proxy or (being a corporation) by a duly authorized representative has one vote for each share held by the shareholder.

Restrictions on Voting Where Sums Overdue on Shares

None of our shareholders (whether present in person by proxy or, in the case of a corporate member, by a duly authorized representative) shall (unless

the directors otherwise determine) be entitled to vote at any general meeting or at any separate class meeting in respect of any share held by him unless all
calls or other sums payable by him in respect of that share have been paid.

Calls on Shares

The directors may from time to time make calls on shareholders in respect of any moneys unpaid on their shares, whether in respect of the nominal

value of the shares or by way of premium. Shareholders are required to pay called amounts on shares subject to receiving at least 14 clear days’ notice
specifying the time and place for payment. If a shareholder fails to pay any part of a call, the directors may serve further notice naming another day not
being less than 14 clear days from the date of the further notice requiring payment and stating that in the event of non-payment the shares in respect of
which the call was made will be liable to be forfeited. Subsequent forfeiture requires a resolution by the directors.

Dividend Rights

Subject to the Companies Act 2006 and the provisions of all other relevant legislation, we may by ordinary resolution declare dividends in
accordance with the respective rights of shareholders but no such dividend shall exceed the amount recommended by the directors. If, in the opinion of the
directors, our profits available for distribution justify such payments, the directors may pay fixed dividends payable on any of our shares with preferential
rights, half-yearly or otherwise, on fixed dates and from time to time pay interim dividends to the holders of any class of shares. Subject to any special
rights attaching to or terms of issue of any shares, all dividends shall be declared and paid according to the amounts paid up on the shares on which the
dividend is paid. No dividend shall be payable to us in respect of any shares held by us as treasury shares (except to the extent permitted by the Companies
Act 2006 and

1

 
 
 
 
 
 
 
 
 
 
 
 
 
any other relevant legislation).  We may, upon the recommendation of the directors, by ordinary resolution, direct payment of a dividend wholly or partly
by the distribution of specific assets.

Distributions of Assets on Winding-up

Subject to any special rights attaching to or the terms of issue of any shares, on any winding-up of the Company our surplus assets remaining after

satisfaction of our liabilities will be distributed among our shareholders in proportion to their respective holdings of shares and the amounts paid up on
those shares.

On any winding-up of the Company (whether the liquidation is voluntary, under supervision or by the Court, the liquidator may with the authority of

a special resolution of the Company and any other sanction required by any relevant legislation, divide among our shareholders (excluding the Company
itself to the extent that it is a shareholder by virtue of its holding any shares or treasury shares) in specie or in kind the whole or any part of our assets
(subject to any special rights attached to any shares issued by us in the future) and may for that purpose set such value as he deems fair upon any one or
more class or classes of property and may determine how that division shall be carried out as between the shareholders or different classes of shareholders.
The liquidator may, with that sanction, vest the whole or any part of the assets in trustees upon such trusts for the benefit of the shareholders as he with the
relevant authority determines, and the liquidation of the Company may be closed and the Company dissolved, but so that no shareholders shall be
compelled to accept any shares or other property in respect of which there is a liability.

Variation of Rights

The rights or privileges attached to any class of shares may (unless otherwise provided by the terms of the issue of the shares of that class) be varied

or abrogated with the consent in writing of the holders of three-fourths in requisite amount of the issued shares of that class (excluding any shares of that
class held as treasury shares) or with the sanction of a special resolution passed at a separate general meeting of the shareholders of that class, but not
otherwise.

Transfer of Shares

All of our shares are in registered form and may be transferred by a transfer in any usual or common form or any form acceptable to the directors and

permitted by the Companies Act 2006 and any other relevant legislation.

Capital Variations

We may, by ordinary resolution, consolidate and divide all or any of our share capital into shares of a larger nominal amount than our existing shares
or sub-divide our shares, or any of them, into shares of a smaller amount than our existing shares. Subject to the provisions of the Companies Act 2006 and
any other relevant legislation, we may by special resolution reduce our share capital, any capital redemption reserve fund or any share premium account
and may redeem or purchase any of our own shares.

Pre-emption Rights

There are no rights of pre-emption under our articles of association in respect of transfers of issued ordinary shares. In certain circumstances, our

shareholders may have statutory pre-emption rights under the Companies Act 2006 in respect of the allotment of new shares in the Company. These
statutory pre-emption rights, when applicable, would require us to offer new shares for allotment to existing shareholders on a pro rata basis before allotting
them to other persons. In such circumstances, the procedure for the exercise of such statutory pre-emption rights would be set out in the documentation by
which such ordinary shares would be offered to our shareholders. These statutory pre-emption rights may be disapplied by a special resolution passed by
shareholders in a general meeting in accordance with the provisions of the Companies Act 2006.

Preferred Shares

Our board of directors may, from time to time, following an ordinary resolution of the ordinary shareholders granting authority to the directors to
allot shares and special resolution of the ordinary shareholders to disapply pre-emption rights (if applicable and not already disapplied), issue preferred
shares with such designations, powers, preferences, privileges, and relative participating, optional or special rights as well as the qualifications, limitations
or restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all of which may
be greater than the rights of the ordinary shares, as determined by an ordinary resolution of the ordinary shareholders (or as set out in the articles of
association following a special resolution of the ordinary shareholders to amend the articles of association). Holders of preferred shares may be entitled to
receive a preference payment in the event of our liquidation before any payment is made to the holders of ordinary shares. There are currently no preferred
shares outstanding, and we have no present intention to issue any preferred shares.

Directors

Unless and until we in a general meeting of our shareholders otherwise determine, the number of directors shall not be subject to any maximum

but shall not be less than two.

General Meetings and Notices

Annual General Meetings

We shall in each year hold a general meeting of our shareholders in addition to any other meetings in that year, and shall specify the meeting as

such in the notice convening it. The annual general meeting shall be held at such time and place as the directors may appoint.

Calling of General Meetings

The directors may call a general meeting of shareholders. The directors must call a general meeting if the shareholders and the Companies Act

2006 require them to do so.

Quorum of Meetings

No business shall be transacted at any general meeting unless a quorum is present when the meeting proceeds to business but the absence of a
quorum shall not preclude the appointment of a chairman that shall not be treated as part of the business of a meeting. One or more qualifying persons
present at a meeting and between them holding (or being the proxy or corporate representative of the holders of) at least one-third in number of the issued
shares (excluding any shares held as treasury shares) entitled to vote on the business to be transacted are a quorum. A qualifying person for these purposes
is an individual who is a member, a person authorized to act as the representative of a member (being a corporation) in relation to the meeting or a person
appointed as proxy of a member in relation to the meeting.

Other U.K. Law Considerations

Mandatory Purchases and Acquisitions

Pursuant to sections 979 to 991 of the Companies Act 2006, where a takeover offer has been made for the Company and the offeror has acquired

or unconditionally contracted to acquire not less than 90 percent of the voting rights carried by those shares, the offeror may give notice to the holder of any
shares to which the offer relates and which the offeror has not acquired or unconditionally contracted to acquire, that he wishes to acquire and is entitled to
so acquire those shares on the same terms as the general offer.

Disclosure of Interest in Shares

Pursuant to Part 22 of the Companies Act 2006 and our articles of association, we are empowered by notice in writing to require any person whom

we know to be, or have reasonable cause to believe to be, interested in the Company, our shares or, at any time during the three years immediately
preceding the date on which the notice is issued has been so interested, within a reasonable time to disclose to us particulars of any interest, rights,
agreements or arrangements affecting any of the shares held by that person or in which such other person as aforesaid is interested (so far as is within his
knowledge).

Under our articles of association, if a person defaults in supplying us with the required particulars in relation to the shares in question (“default

shares”), the directors may by notice direct that:

·

·

in respect of the default shares, the relevant member shall not be entitled to vote or exercise any other right conferred by membership in
relation to general meetings; and/or

where the default shares represent at least 0.25 percent of their class, (a) any dividend or other money payable in respect of the default
shares shall be retained by us without liability to pay interest, and/or (b) no transfers by the relevant member of shares other than certain
approved transfers may be registered (unless the member himself is not in default and the transfer does not relate to default shares), and/or
(c) any shares held by the relevant number in uncertificated form shall be converted into certificated form.

Purchase of Own Shares

Under English law, a public limited company may only purchase its own shares out of the distributable profits of the company or the proceeds of a
fresh issue of shares made for the purpose of financing the purchase. A limited company may not purchase its own shares if as a result of the purchase there
would no longer be any issued shares of the company other than redeemable shares or shares held as treasury shares.

Subject to the above, we may purchase our own shares in the manner prescribed below. We may purchase on a recognized investment exchange

our own fully paid shares pursuant to an ordinary resolution of the Company. The resolution authorizing the purchase must:

·

·

·

specify the maximum number of shares authorized to be acquired;

determine the maximum and minimum prices that may be paid for the shares; and

specify a date, not being later than five years after the passing of the resolution, on which the authority to purchase is to expire.

We may purchase our own fully paid shares otherwise than on a recognized investment exchange pursuant to a purchase contract authorized by

special resolution of the Company before the purchase takes place. Any authority will not be effective if any shareholder from whom we propose to
purchase shares votes on the resolution and the resolution would not have been passed if he had not done so. The resolution authorizing the purchase must
specify a date, not being later than five years after the passing of the resolution, on which the authority to purchase is to expire.

Takeover Provisions

If at the time of a takeover offer the U.K. Panel on Takeovers and Mergers (the “Takeover Panel”) determines that we have our place of central

management and control in the United Kingdom, we would be subject  to the U.K. City Code on Takeovers and Mergers (the “Takeover Code”), which is
issued and administered by the Takeover Panel. The Takeover Code provides a framework within which takeovers of companies subject to it are conducted,
including, in particular, certain rules in respect of mandatory offers.

In July 2018, the Takeover Panel confirmed that, based on our current circumstances, we are not subject to the Takeover Code. As a result, our

shareholders are not entitled to the benefit of certain takeover offer protections provided under the Takeover Code. We believe that this position is unlikely
to change at any time in the near future but, in accordance with good practice, we will review the situation on a regular basis and consult with the Takeover
Panel if there is any change in our circumstances which may have a bearing on whether the Takeover Panel would determine our place of central
management and control to be in the United Kingdom.

Exchange Controls

There are no governmental laws, decrees, regulations or other legislation in the United Kingdom that may affect the import or export of capital,

including the availability of cash and cash equivalents for use by us, or that may affect the remittance of dividends, interest, or other payments by us to non-
resident holders of our ordinary shares or ordinary shares, other than withholding tax requirements. There is no limitation imposed by English law or our
articles of association on the right of non-residents to hold or vote shares.

Market Listing

Our ADSs are listed on The Nasdaq Global Select Market under the symbol “ADAP.”

DESCRIPTION OF AMERICAN DEPOSITARY SHARES

Citibank, N.A. (the “Depositary”) has agreed to act as the depositary bank for the American Depositary Shares. Citibank’s depositary offices are
located at 388 Greenwich Street, New York, New York 10013. American Depositary Shares are frequently referred to as “ADSs” and represent ownership
interests in securities that are on deposit with the depositary bank. ADSs may be represented by certificates that are commonly known as “American
Depositary Receipts” or “ADRs.” The depositary bank typically appoints a custodian to safekeep the securities on deposit. In this case, the custodian is
Citibank, N.A. London Branch, having its principal office at Citigroup Centre, Canada Square, Canary Wharf, London E14 5LB, England.

We have appointed Citibank as depositary bank pursuant to a deposit agreement. A copy of the deposit agreement is on file with the SEC under

cover of a Registration Statement on Form F-6. A copy of the deposit agreement is available from the SEC’s website (www.sec.gov). Please refer to
Registration Number 333-203642, Registration Number 333-212714 or Registration Number 333-233560 when retrieving such copy.

“Holder” means the person or persons in whose name an ADS is registered on the register maintained by the Depositary for such purpose.

Each ADS represents the right to receive 12 ordinary shares, each of which is frequently referred to as a “Share” or collectively, as “Shares”, on

deposit with the custodian. An ADS also represents the right to receive any other property received by the depositary bank or the custodian on behalf of the
owner of the ADS but that has not been distributed to the owners of ADSs because of legal restrictions or practical considerations. The custodian, the
depositary bank and their respective nominees will hold all deposited property for the benefit of the holders and beneficial owners of ADSs. The deposited
property does not constitute the proprietary assets of the depositary bank, the custodian or their nominees. Beneficial ownership in the deposited property
will under the terms of the deposit agreement be vested in the beneficial owners of the ADSs. The depositary bank, the custodian and their respective
nominees will be the record holders of the deposited property represented by the ADSs for the benefit of the holders and beneficial owners of the
corresponding ADSs. Owners of ADSs will be able to exercise beneficial ownership interests in the deposited property only through the registered holders
of the ADSs, by the registered holders of the ADSs (on behalf of the applicable ADS owners) only through the depositary bank, and by the depositary bank
(on behalf of the owners of the corresponding ADSs) directly, or indirectly through the custodian or their respective nominees, in each case upon the terms
of the deposit agreement.

 If you become an owner of ADSs, you will become a party to the deposit agreement and therefore will be bound to its terms and to the terms of

any ADR that represents your ADSs. The deposit agreement and the ADR specify our rights and obligations as well as your rights and obligations as owner
of ADSs and those of the depositary bank. As an ADS holder, you appoint the depositary bank to act on your behalf in certain circumstances. The deposit
agreement and the ADRs are governed by New York law. However, our obligations to the holders of Shares will continue to be governed by the laws of
England and Wales, which may be different from the laws in the United States.

In addition, applicable laws and regulations may require you to satisfy reporting requirements and obtain regulatory approvals in certain
circumstances. You are solely responsible for complying with such reporting requirements and obtaining such approvals. Neither the depositary bank, the
custodian, us nor any of their or our respective agents or affiliates shall be required to take any actions whatsoever on your behalf to satisfy such reporting
requirements or obtain such regulatory approvals under applicable laws and regulations.

As an owner of ADSs, we will not treat you as one of our shareholders and you will not have direct shareholder rights. The depositary bank will hold on
your behalf the shareholder rights attached to the Shares underlying your ADSs. As an owner of ADSs you will be able to exercise the shareholders rights
for the Shares represented by your ADSs through the depositary bank only to the extent contemplated in the deposit agreement. To exercise any shareholder
rights not contemplated in the deposit agreement you will, as an ADS owner, need to arrange for the cancellation of your ADSs and become a direct
shareholder.

Dividends and Distributions

Holders generally have the right to receive the distributions we make on the securities deposited with the custodian. A Holder’s receipt of these

distributions may be limited, however, by practical considerations and legal limitations. Holders will receive such distributions under the terms of the
deposit agreement in proportion to the number of ADSs held as of the specified record date, after deduction of the applicable fees, taxes and expenses.

5

 
 
 
 
 
 
 
 
 
Distributions of Cash

Whenever we make a cash distribution for the securities on deposit with the custodian, we will deposit the funds with the custodian. Upon receipt
of confirmation of the deposit of the requisite funds, the depositary bank will arrange for the funds to be converted into U.S. dollars and for the distribution
of the U.S. dollars to the holders, subject to the laws and regulations of England and Wales.

The conversion into U.S. dollars will take place only if practicable and if the U.S. dollars are transferable to the United States. The depositary bank

will apply the same method for distributing the proceeds of the sale of any property (such as undistributed rights) held by the custodian in respect of
securities on deposit.

The distribution of cash will be made net of the fees, expenses, taxes and governmental charges payable by holders under the terms of the deposit

agreement. The depositary bank will hold any cash amounts it is unable to distribute in a non-interest bearing account for the benefit of the applicable
holders and beneficial owners of ADSs until the distribution can be effected or the funds that the depositary bank holds must be escheated as unclaimed
property in accordance with the laws of the relevant states of the United States.

Distributions of Shares

Whenever we make a free distribution of ordinary shares for the securities on deposit with the custodian, we will deposit the applicable number of

ordinary shares with the custodian. Upon receipt of confirmation of such deposit, the depositary bank will either distribute to holders new ADSs
representing the ordinary shares deposited or modify the ADS-to-ordinary share ratio, in which case each ADS a Holder holds will represent rights and
interests in an integral number of the additional ordinary shares so deposited. Only whole new ADSs will be distributed. Fractional entitlements will be sold
and the proceeds of such sale will be distributed as in the case of a cash distribution.

The distribution of new ADSs or the modification of the ADS-to-ordinary share ratio upon a distribution of ordinary shares will be made net of the

fees, expenses, taxes and governmental charges payable by holders under the terms of the deposit agreement. In order to pay such taxes or governmental
charges, the depositary bank may sell all or a portion of the new ordinary shares so distributed.

No such distribution of new ADSs will be made if it would violate a law (i.e., the U.S. securities laws) or if it is not  practicable. If the depositary
bank does not distribute new ADSs as described above, it may sell the ordinary shares received upon the terms described in the deposit agreement and will
distribute the proceeds of the sale as in the case of a distribution of cash.

Distributions of Rights

Whenever we intend to distribute rights to purchase additional ordinary shares, we will give prior notice to the depositary bank and will indicate

whether we wish the elective distribution to be made available to you. In such case, we will assist the depositary bank in determining whether such
distribution is lawful and reasonably practicable to distribute rights to purchase additional ADSs to holders.

The depositary bank will establish procedures to distribute rights to purchase additional ADSs to holders and to enable such holders to exercise

such rights if it is lawful and reasonably practicable to make the rights available to holders of ADSs, we indicate that we wish such rights to be made
available to holders of ADSs, and if we provide all of the documentation contemplated in the deposit agreement (such as opinions to address the lawfulness
of the transaction). A Holder may have to pay fees, expenses, taxes and other governmental charges to subscribe for the new ADSs upon the exercise of a
Holder’s rights. The depositary bank is not obligated to establish procedures to facilitate the distribution and exercise by holders of rights to purchase new
ordinary shares other than in the form of ADSs.

The depositary bank will not distribute the rights to a Holder if:
· We do not timely request that the rights be distributed to a Holder or we request that the rights not be distributed to a Holder; or
· We fail to deliver satisfactory documents to the depositary bank; or
·

It is not reasonably practicable to distribute the rights.

The depositary bank will sell the rights that are not exercised or not distributed if such sale is lawful and reasonably practicable. The proceeds of

such sale will be distributed to holders as in the case of a cash distribution. If the depositary bank is unable to sell the rights, it will allow the rights to lapse.

6

 
 
 
 
 
 
 
 
 
 
 
 
Elective Distributions

Whenever we intend to distribute a dividend payable at the election of shareholders either in cash or in additional shares, we will give prior notice

thereof to the depositary bank and will indicate whether we wish the elective distribution to be made available to a Holder. In such case, we will assist the
depositary bank in determining whether such distribution is lawful and reasonably practicable.

The depositary bank will make the election available to a Holder only if it is lawful and reasonably practicable, we indicate that we wish such

election to be made available to holders of ADSs, and if we have provided all of the documentation contemplated in the deposit agreement. In such case, the
depositary bank will establish procedures to enable a Holder to elect to receive either cash or additional ADSs, in each case as described in the deposit
agreement.

If the election is not made available to a Holder, such Holder will receive either cash or additional ADSs, upon the terms described above for
distributions of cash and ordinary shares, respectively, depending on what a shareholder in England and Wales would receive upon failing to make an
election, as more fully described in the deposit agreement.

Other Distributions

Whenever we intend to distribute property other than cash, ordinary shares or rights to purchase additional ordinary shares, we will notify the

depositary bank in advance and will indicate whether we wish such distribution to be made to Holders. If so, we will assist the depositary bank in
determining whether such distribution to holders is lawful and reasonably practicable.

If it is reasonably practicable to distribute such property to a Holder, we indicate that we wish such distribution to be made available to holders of
ADSs, and if we provide all of the documentation contemplated in the deposit agreement, the depositary bank will distribute the property to the holders in a
manner it deems practicable.

The distribution will be made net of fees, expenses, taxes and governmental charges payable by holders under the terms of the deposit agreement.

In order to pay such taxes and governmental charges, the depositary bank may sell all or a portion of the property received.

The depositary bank will not distribute the property to a Holder and will sell the property if:

· We do not request that the property be distributed to a Holder or if we ask that the property not be distributed to a Holder; or
· We do not deliver satisfactory documents to the depositary bank; or
·

The depositary bank determines that all or a portion of the distribution to a Holder is not reasonably practicable.

The proceeds of such a sale will be distributed to holders as in the case of a cash distribution.

Redemption

Whenever we decide to redeem any of the securities on deposit with the custodian, we will notify the depositary bank in advance. If it is practicable

and if we provide all of the documentation contemplated in the deposit agreement, the depositary bank will provide notice of the redemption to the holders.

The custodian will be instructed to surrender the shares being redeemed against payment of the applicable redemption price. The depositary bank

will convert the redemption funds received into U.S. dollars upon the terms of the deposit agreement and will establish procedures to enable holders to
receive the net proceeds from the redemption upon surrender of their ADSs to the depositary bank. A Holder may have to pay fees, expenses, taxes and
other governmental charges upon the redemption of a Holder’s ADSs. If less than all ADSs are being redeemed, the ADSs to be retired will be selected by
lot or on a pro rata basis, as the depositary bank may determine.

Changes Affecting Ordinary Shares

The ordinary shares held on deposit for a Holder’s ADSs may change from time to time. For example, there may be a change in nominal or par

value, a split-up, cancellation, consolidation or any other reclassification of such ordinary shares or a recapitalization, reorganization, merger, consolidation
or sale of assets of the Company.

7

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If any such change were to occur, a Holder’s ADSs would, to the extent permitted by law, represent the right to receive the property received or

exchanged in respect of the ordinary shares held on deposit. The depositary bank may in such circumstances deliver new ADSs to a Holder, amend the
deposit agreement, the ADRs and the applicable Registration Statement(s) on Form F-6, call for the exchange of a Holder’s existing ADSs for new ADSs
and take any other actions that are appropriate to reflect as to the ADSs the change affecting the Shares. If the depositary bank may not lawfully distribute
such property to a Holder, the depositary bank may sell such property and distribute the net proceeds to a Holder as in the case of a cash distribution.

Issuance of ADSs upon Deposit of Ordinary Shares

The depositary bank may create ADSs on a Holder’s behalf if a Holder or a Holder’s broker deposit ordinary shares with the custodian. The

depositary bank will deliver these ADSs to the person a Holder indicates only after a Holder pays any applicable issuance fees and any charges and taxes
payable for the transfer of the ordinary shares to the custodian. A Holder’s ability to deposit ordinary shares and receive ADSs may be limited by U.S. and
English legal considerations applicable at the time of deposit.

The issuance of ADSs may be delayed until the depositary bank or the custodian receives confirmation that all required approvals have been given

and that the ordinary shares have been duly transferred to the custodian. The depositary bank will only issue ADSs in whole numbers.

When a Holder makes a deposit of ordinary shares, a Holder will be responsible for transferring good and valid title to the depositary bank. As

such, a Holder will be deemed to represent and warrant that:

·
·
·
·

·

The ordinary shares are duly authorized, validly issued, fully paid, non-assessable and legally obtained.
All preemptive (and similar) rights, if any, with respect to such ordinary shares have been validly waived or exercised.
A Holder is duly authorized to deposit the ordinary shares.
The ordinary shares presented for deposit are free and clear of any lien, encumbrance, security interest, charge, mortgage or adverse claim,
and are not, and the ADSs issuable upon such deposit will not be, “restricted securities” (as defined in the deposit agreement).
The ordinary shares presented for deposit have not been stripped of any rights or entitlements.

If any of the representations or warranties are incorrect in any way, we and the depositary bank may, at a Holder’s cost and expense, take any and

all actions necessary to correct the consequences of the misrepresentations.

Transfer, Combination and Split Up of ADRs

ADR Holders will be entitled to transfer, combine or split up such Holder’s ADRs and the ADSs evidenced thereby. For transfers of ADRs, a

Holder will have to surrender the ADRs to be transferred to the depositary bank and also must:

·
·

·

ensure that the surrendered ADR is properly endorsed or otherwise in proper form for transfer;
provide such proof of identity and genuineness of signatures as the depositary bank deems appropriate; provide any transfer stamps required
by the State of New York or the United States; and
pay all applicable fees, charges, expenses, taxes and other government charges payable by ADR holders pursuant to the terms of the deposit
agreement, upon the transfer of ADRs.

To have a Holder’s ADRs either combined or split up, such Holder must surrender the ADRs in question to the depositary bank with such
Holder’s request to have them combined or split up, and such Holder must pay all applicable fees, charges and expenses payable by ADR holders, pursuant
to the terms of the deposit agreement, upon a combination or split up of ADRs.

Withdrawal of Ordinary Shares Upon Cancellation of ADSs

ADS Holders will be entitled to present such Holder’s ADSs to the depositary bank for cancellation and then receive the corresponding number of
underlying ordinary shares at the custodian’s offices. A Holder’s ability to withdraw the ordinary shares held in respect of the ADSs may be limited by U.S.
and English considerations applicable at the time of withdrawal. In order to withdraw the ordinary shares represented by a Holder’s ADSs, such Holder will
be required to pay to the depositary bank the fees for cancellation of ADSs and any charges and taxes payable upon the transfer of the ordinary shares being
withdrawn. A Holder assumes the risk for delivery of all funds and securities upon withdrawal. Once canceled, the ADSs will not have any rights under the
deposit agreement.

The depositary bank may ask a Holder to provide proof of identity and genuineness of any signature and such other documents as the depositary

bank may deem appropriate before it will cancel a Holder’s ADSs. The withdrawal of the ordinary shares

8

 
 
 
 
 
 
 
 
 
 
 
 
 
represented by a Holder’s ADSs may be delayed until the depositary bank receives satisfactory evidence of compliance with all applicable laws and
regulations. Please keep in mind that the depositary bank will only accept ADSs for cancellation that represent a whole number of securities on deposit.

Holders will have the right to withdraw the securities represented by such Holder’s ADSs at any time except for:

·

·
·

Temporary delays that may arise because (i) the transfer books for the ordinary shares or ADSs are closed, or (ii) ordinary shares are
immobilized on account of a shareholders’ meeting or a payment of dividends;
Obligations to pay fees, taxes and similar charges; and
Restrictions imposed because of laws or regulations applicable to ADSs or the withdrawal of securities on deposit.

The deposit agreement may not be modified to impair a Holder’s right to withdraw the securities represented by a Holder’s ADSs except to

comply with mandatory provisions of law.

Voting Rights

Holders generally have the right under the deposit agreement to instruct the depositary bank to exercise the voting rights for the ordinary shares

represented by a Holder’s ADSs. The voting rights of holders of ordinary shares are described above in “Ordinary Shares—Voting Rights.”

At our request, the depositary bank will distribute to a Holder any notices of shareholders’ meetings received from us together with information

explaining how to instruct the depositary bank to exercise the voting rights of the securities represented by ADSs.

If the depositary bank timely receives voting instructions from a holder of ADSs, it will endeavor to vote the securities (in person or by proxy)

represented by the holder’s ADSs in accordance with the voting instructions received from such holder and as follows.

·

·

In the event of voting by show of hands, the Depositary will vote (or cause the custodian to vote) all Shares held on deposit at that time in
accordance with the voting instructions received from a majority of holders of ADSs who provide timely voting instructions.
In the event of voting by poll, the Depositary will vote (or cause the custodian to vote) the Shares held on deposit in accordance with the
voting instructions received from the holders of ADSs. Under certain limited circumstances described in the deposit agreement, a person
designated by us shall be entitled to vote the Shares held on deposit for which voting instructions have not been timely received by the
depositary from holders of ADSs.

Securities for which no voting instructions have been received will not be voted (except as otherwise contemplated herein). Please note that the

ability of the depositary bank to carry out voting instructions may be limited by practical and legal limitations and the terms of the securities on deposit. We
cannot assure that Holders will receive voting materials in time to enable such Holder to return voting instructions to the depositary bank in a timely manner.

Depositary Services

  Up to U.S. 5¢ per ADS held on the applicable record date(s) established

by the depositary bank

As an ADS holder you will also be responsible for paying certain fees and expenses incurred by the depositary bank and certain taxes and

governmental charges such as:

·

·
·
·

·

·

Fees for the transfer and registration of Shares or other deposited securities, including those charged by the registrar and transfer agent for
the Shares in England and Wales (i.e., upon deposit and withdrawal of Shares).
Expenses incurred for converting foreign currency into U.S. dollars.
Expenses for cable, telex and fax transmissions and for delivery of securities.
Taxes and duties (including applicable interest and penalties) and other governmental charges, including upon the transfer of securities (i.e.,
when Shares are deposited or withdrawn from deposit).
Fees and expenses as are incurred by the depositary bank in connection with compliance with exchange control regulations and other
regulatory requirements applicable to Shares, deposited securities, ADSs and ADRs.
Fees and expenses incurred in connection with the delivery or servicing of Shares and other property on deposit.

Depositary fees payable upon the issuance and cancellation of ADSs are typically paid to the depositary bank by the brokers (on behalf of their
clients) receiving the newly issued ADSs from the depositary bank and by the brokers (on behalf of their clients) delivering the ADSs to the depositary
bank for cancellation. The brokers in turn charge these fees to their clients. Depositary fees payable in connection with distributions of cash or securities to
ADS holders and the depositary services fee are charged by the depositary bank to the holders of record of ADSs as of the applicable ADS record date.

The Depositary fees payable for cash distributions are generally deducted from the cash being distributed. In the case of distributions other than

cash (i.e., stock dividend, rights), the depositary bank charges the applicable fee to the ADS record date holders concurrent with the distribution. In the case
of ADSs registered in the name of the investor (whether certificated or uncertificated in direct registration), the depositary bank sends invoices to the
applicable record date ADS holders. In the case of ADSs held in brokerage and custodian accounts (via DTC), the depositary bank generally collects its
fees through the systems provided by DTC (whose nominee is the registered holder of the ADSs held in DTC) from the brokers and custodians holding
ADSs in their DTC accounts. The brokers and custodians who hold their clients’ ADSs in DTC accounts in turn charge their clients’ accounts the amount of
the fees paid to the depositary banks.

In the event of a refusal to pay the depositary fees, the depositary bank may, under the terms of the deposit agreement, refuse the requested service

until payment is received or may set off the amount of the depositary fees from any distribution to be made to the ADS holder.

Note that the fees and charges you may be required to pay may vary over time and may be changed by us and by the depositary bank. You will

receive prior notice of such changes.

The depositary bank may reimburse us for certain expenses incurred by us in respect of the ADS program established pursuant to the deposit

agreement, by making available a portion of the depositary fees charged in respect of the ADS program or otherwise, upon such terms and conditions as we
and the depositary bank may agree from time to time.

Amendments and Termination

We may agree with the depositary bank to modify the deposit agreement at any time without a Holder’s consent. We undertake to give holders 30
days’ prior notice of any modifications that would materially prejudice any of their substantial rights under the deposit agreement. We will not consider to
be materially prejudicial to a Holder’s substantial rights any modifications or supplements that are reasonably necessary for the ADSs to be registered under
the Securities Act or to be eligible for book-entry settlement, in each case without imposing or increasing the fees and charges such Holder is required to
pay. In addition, we may not be able to provide Holders with prior notice of any modifications or supplements that are required to accommodate
compliance with applicable provisions of law.

Holders will be bound by the modifications to the deposit agreement if such Holder’s continue to hold ADSs after the modifications to the deposit

agreement become effective. The deposit agreement cannot be amended to prevent a Holder from withdrawing the ordinary shares represented by such
Holder’s ADSs (except as permitted by law).

10

 
 
 
 
 
 
 
 
 
 
 
 
 
 
We have the right to direct the depositary bank to terminate the deposit agreement. Similarly, the depositary bank may in certain circumstances on

its own initiative terminate the deposit agreement. In either case, the depositary bank must give notice to the holders at least 30 days before termination.
Until termination, a Holder’s rights under the deposit agreement will be unaffected.

After termination, the depositary bank will continue to collect distributions received (but will not distribute any such property until a Holder

request the cancellation of such Holder’s ADSs) and may sell the securities held on deposit. After the sale, the depositary bank will hold the proceeds from
such sale and any other funds then held for the holders of ADSs in a non-interest bearing account. At that point, the depositary bank will have no further
obligations to holders other than to account for the funds then held for the holders of ADSs still outstanding (after deduction of applicable fees, taxes and
expenses).

Books of Depositary

The depositary bank will maintain ADS holder records at its depositary office. Holders may inspect such records at such office during regular

business hours but solely for the purpose of communicating with other holders in the interest of business matters relating to the ADSs and the deposit
agreement.

The depositary bank will maintain in New York facilities to record and process the issuance, cancellation, combination, split-up and transfer of

ADSs. These facilities may be closed from time to time, to the extent not prohibited by law.

Limitations on Obligations and Liabilities

The deposit agreement limits our obligations and the depositary bank’s obligations to Holders. Please note the following:

· We and the depositary bank are obligated only to take the actions specifically stated in the deposit agreement without negligence or bad

·

·

faith.
The depositary bank disclaims any liability for any failure to carry out voting instructions, for any manner in which a vote is cast or for the
effect of any vote, provided it acts in good faith and in accordance with the terms of the deposit agreement.
The depositary bank disclaims any liability for any failure to determine the lawfulness or practicality of any action, for the content of any
document forwarded to Holders on our behalf or for the accuracy of any translation of such a document, for the investment risks associated
with investing in ordinary shares, for the validity or worth of the ordinary shares, for any tax consequences that result from the ownership of
ADSs, for the credit-worthiness of any third party, for allowing any rights to lapse under the terms of the deposit agreement, for the
timeliness of any of our notices or for our failure to give notice.

· We and the depositary bank will not be obligated to perform any act that is inconsistent with the terms of the deposit agreement.
· We and the depositary bank disclaim any liability if we or the depositary bank are prevented or forbidden from or subject to any civil or
criminal penalty or restraint on account of, or delayed in, doing or performing any act or thing required by the terms of the deposit
agreement, by reason of any provision, present or future of any law or regulation, or by reason of present or future provision of any provision
of our articles of association or any provision of or governing the securities on deposit, or by reason of any act of God or war or other
circumstances beyond our control.

· We and the depositary bank disclaim any liability by reason of any exercise of, or failure to exercise, any discretion provided for in the

deposit agreement or in our articles of association or in any provisions of or governing the securities on deposit.

· We and the depositary bank further disclaim any liability for any action or inaction in reliance on the advice or information received from

legal counsel, accountants, any person presenting Shares for deposit, any holder of ADSs or authorized representatives thereof, or any other
person believed by either of us in good faith to be competent to give such advice or information.

· We and the depositary bank also disclaim liability for the inability by a holder to benefit from any distribution, offering, right or other benefit

that is made available to holders of ordinary shares but is not, under the terms of the deposit agreement, made available to Holders.

· We and the depositary bank may rely without any liability upon any written notice, request or other document believed to be genuine and to

have been signed or presented by the proper parties.

· We and the depositary bank also disclaim liability for any consequential or punitive damages for any breach of the terms of the deposit

agreement.
No disclaimer of any Securities Act liability is intended by any provision of the deposit agreement.

Taxes

A Holder will be responsible for the taxes and other governmental charges payable on the ADSs and the securities represented by the ADSs. We,

the depositary bank and the custodian may deduct from any distribution the taxes and governmental charges payable by holders and may sell any and all
property on deposit to pay the taxes and governmental charges payable by holders. You will be liable for any deficiency if the sale proceeds do not cover
the taxes that are due.

The depositary bank may refuse to issue ADSs, to deliver, transfer, split-up or combine ADRs or to release securities on deposit until all taxes and

charges are paid by the applicable holder. The depositary bank and the custodian may take reasonable administrative actions to obtain tax refunds and
reduced tax withholding for any distributions on your behalf. However, you may be required to provide to the depositary bank and to the custodian proof of
taxpayer status and residence and such other information as the depositary bank and the custodian may require to fulfill legal obligations. You are required
to indemnify us, the depositary bank and the custodian for any claims with respect to taxes based on any tax benefit obtained for you.

Foreign Currency Conversion

The depositary bank will arrange for the conversion of all foreign currency received into U.S. dollars if such conversion is practical, and it will
distribute the U.S. dollars in accordance with the terms of the deposit agreement. You may have to pay fees and expenses incurred in converting foreign
currency, such as fees and expenses incurred in complying with currency exchange controls and other governmental requirements.

If the conversion of foreign currency is not practicable or lawful, or if any required approvals are denied or not obtainable at a reasonable cost or

within a reasonable period, the depositary bank may take the following actions in its discretion:

·

·
·

Convert the foreign currency to the extent practical and lawful and distribute the U.S. dollars to the holders for whom the conversion and
distribution is lawful and practical.
Distribute the foreign currency to holders for whom the distribution is lawful and practical.
Hold the foreign currency (without liability for interest) for the applicable holders.

Governing Law/Waiver of Jury Trial

The deposit agreement, the ADRs and the ADSs will be interpreted in accordance with the laws of the State of New York.  The rights of holders of ordinary
shares (including ordinary shares represented by ADSs) are governed by the laws of England and Wales.  As an owner of ADSs, holders irrevocably agree
that any legal action arising out of the Deposit Agreement, the ADSs or the ADRs, involving the Company or the Depositary, may only be instituted in a
state or federal court in the city of New York.

Upon any sale or other disposal of a Product that should be included within Net Sales for any consideration other than
an exclusively monetary consideration on bona fide arm’s length terms, then for purposes of calculating the Net Sales under
this Agreement, such Product or Competitive Product shall be deemed to be sold exclusively for money at the average sales
price  during  the  applicable  reporting  period  generally  achieved  for  such  Product  or  Competitive  Product  in  the  country  in
which  such  sale  or  other  disposal  occurred  when  such  Product  or  Competitive  Product  is  sold  alone  and  not  with  other

Product  (an  “Other  Component”);  or  (2)  is  sold  in  a  form  that  is  any  combination  of  a  Base  Product  and  another
pharmaceutical  or  therapeutic  product  that  contains  at  least  one  Other  Component,  where  such  Base  Product  or  Other
Component are not formulated together but are sold together (e.g., bundled) as a single product and invoiced as one product
(in either case ((1) or (2)), a “Combination Product”), then the Net Sales of such Combination Product for the purpose of
calculating payments owed under this Agreement for sales of such Combination Product, shall be determined as follows: first,
Selling Party shall determine the actual Net Sales of such Combination Product (using the above provisions) and then such
amount shall be multiplied by the fraction A/(A+B), where A is the invoice price of such Base Product, if sold separately, and
B  is  the  total  invoice  price  of  the  Other  Component  if  sold  separately.  If  the  Other  Component  is  not  sold  separately,  Net
Sales  shall  be  calculated  by  multiplying  actual  Net  Sales  of  such  Combination  Product  by  a  fraction A/C  where A  is  the
invoice price of such Base Product if sold separately and C is the invoice price of such Combination Product. If the Product is
not sold separately but the Other Component is sold separately, then Net Sales shall be calculated by multiplying actual Net
Sales of such Combination Product by a fraction 1-B/C where B is the invoice price of the Other

11

Component if sold separately and C is the invoice price of such Combination Product.  If neither such Base Product nor the
Other  Component  is  sold  separately,  then  the  adjustment  to  Net  Sales  shall  be  determined  by  the  Parties  in  good  faith  to
reasonably reflect the fair market value of the contribution of such Base Product in such Combination Product to the total fair
market value of such Combination Product.

Notwithstanding the foregoing, Net Sales shall not include amounts received (whether actually existing or deemed to
exist for purposes of calculation) for Product or Competitive Products not packaged for commercial use or distributed for use
in clinical trials.

will attend all meetings of the subcommittees (e.g. JRC, JDC, JCC, JMAC, and the JFC), and will support the co-chairpersons
of  the  JSC  and  each  subcommittee  in  the  discharge  of  his  or  her  responsibilities.   Alliance  Managers  will  be  non-voting
participants in all JSC and

19

 
 
 
subcommittee  meetings,  but  an Alliance  Manager  may  bring  any  matter  to  the  attention  of  the  JSC  or  any  subcommittee  if
such Alliance  Manager  reasonably  believes  that  such  matter  warrants  such  attention.    Each  Party  will  designate  its  initial
Alliance Manager promptly after the Effective Date and each Party may change its designated Alliance Manager at any time
upon written notice to the other Party.  Any Alliance Manager may designate a substitute to temporarily perform the functions
of  that Alliance  Manager  by  written  notice  to  the  other  Party.    Each Alliance  Manager  will  also:  (a)  be  the  point  of  first
referral in all matters of conflict resolution; (b) provide a single point of communication for seeking consensus between the
Parties regarding key strategy and plan issues; (c) identify and bring disputes to the attention of the JSC in a timely manner;

PRE-DESIGNATION RESEARCH PROGRAM

3.1              Identification And  Validation  Of  Targets .    From  the  Effective  Date  and  continuing  from  time  to  time
thereafter  until  the  Target  Identification  and  Tracking  End  Date,  the  Parties  shall  use  Commercially  Reasonable  Efforts  to
identify and nominate Targets as set forth in this Article 3 (Pre-Designation Research Program) based on data and results that
are in the public domain or that have been generated prior to the Effective Date.  Each Party shall provide any information
relevant  to  Targets  being  discussed  and  shall  collaborate  to  assess  and  identify  Targets  suitable  for  nomination  as
Collaboration  Targets,  but  in  no  event  shall Adaptimmune  be  required  to  perform  any  additional  activities  to  validate  any
Target nominated for designation as a Collaboration Target or a Universal Cells Program Target, in each case, that are not set
forth  in  a  Collaboration  Research  Plan.    Each  Party  shall  be  responsible  for  its  own  costs  and  expenses  in  connection  with
activities under this Section 3.1 (Identification and Validation of Targets), but not activities under any Collaboration Research
Plan, the allocation between the Parties for costs and expenses thereunder is set forth in Section 4.5 (Collaboration Research
Program Costs).

3.2       Nomination.

3.2.1    Collaboration Targets.  The JRC shall nominate and submit to the JSC for approval (a) the first (1 )
st
Target  to  be  nominated  for  designation  as  a  Collaboration  Target  within  [***]  after  the  Effective  Date  (the  “ First
Collaboration  Target  Nomination  Date”),  (b)  the  second  (2 )  Target  to  be  nominated  for  designation  as  a  Collaboration
nd
Target within [***] after the First Collaboration Target Nomination Date (the “ Second  Collaboration  Target  Nomination
Date”), and (c) the third (3 ) Target to be nominated for designation as a Collaboration Target within [***] after the Second
Collaboration Target Nomination Date (the “Third Collaboration Target Nomination Date”).

rd

3.2.2    Universal Cells Program Targets.  Commencing on the Effective Date and continuing until the [***]
anniversary thereafter, Universal Cells shall have the right to nominate, by providing written notice to the JRC, Targets for
designation as Universal Cells Program Targets.

3.2.3    Target Maximums.  A maximum of three (3) distinct Targets shall be nominated for designation, or so
designated, as Collaboration Targets under this Agreement ([***]).  A maximum of two (2) distinct Universal Cells Program
Targets may be nominated for designation at a given time, or so designated, as Universal Cells Program Targets.

3.2.4        Nomination  Exclusivity.    Once  a  Target  is  nominated  for  designation  as  a  Collaboration  Target,  it
cannot also be nominated for designation as a Universal Cells Program Target, and once a Target is nominated for designation
as a Universal Cells Program Target, it cannot also be nominated for designation as a Collaboration Target.  Upon nomination
of a Target and until such Target is designated or finally determined to be either an Excluded Target or a Target for which
Burdened  Technology  Clearance  is  obtained  in  accordance  with  Section  3.3  (Designation  of  Nominated  Targets),
Adaptimmune shall not, itself or with or through an Affiliate or a Third Party, commence any Development activities it is not
conducting at the time of

30

 
nomination with respect to Cell products specific to such Target, or grant any Third Party any rights to conduct such activities,
except to the extent necessary to evaluate such Target for designation as a Collaboration Target or Universal Cells Program
Target, as applicable, unless and until such Target is determined to be an Excluded Target or is designated as a Collaboration
Target  or  Universal  Cells  Program  Target  (in  which  case  such  activities  would  be  permitted  within  the  scope  of  this
Agreement).

3.3       Designation of Nominated Targets.  Upon written notice provided to the JRC of the nomination of a Target
for designation as a Collaboration Target or a Universal Cells Program Target as set forth above, the JRC shall first determine
within [***] days of the nomination thereof whether such Target is an Excluded Target, and if so, whether such Target should
receive Excluded Target Clearance as set forth in Section 3.3.1 (Excluded Targets).  If the JRC determines that such Target is
not an Excluded Target, or if the JRC determines such Target is an Excluded Target but receives Excluded Target Clearance
for such Target, then within [***] days after such determination is made or such Excluded Target Clearance is received, the
Parties  shall  determine  whether  Burdened  Technology  Limitations  applicable  to  such  Target  and  Products  Directed  to  such
Target  exist  pursuant  to  Section  3.3.2  (Acceptance  of  Burdened  Technology),  and  if  so,  whether  the  JSC  will  provide
Burdened Technology Clearance as set forth in Section 3.3.3(b) (Notice Obligations).  If no Burdened Technology Limitations
apply  to  such  Target,  or  such  Target  receives  Burdened  Technology  Clearance,  then  such  nominated  Target  shall  be
designated  as  a  Collaboration  Target  or  Universal  Cells  Program  Target  (as  applicable).    A  decision  as  to  whether  any
nominated Target will be designated as a Collaboration Target or a Universal Cells Program Target shall be made within [***]
of the nomination of such Target.

3.3.1    Excluded Targets.  Adaptimmune shall maintain a complete list of Targets that are Excluded Targets
from the Effective Date until the Target Identification and Tracking End Date, with such list including the date on which each
listed Target becomes an Excluded Target.  The Excluded Target list shall be made available in the event of a dispute under
Section 3.3.6 (Dispute as to Excluded Targets) to the mutually acceptable Expert, who shall not disclose the content of such
list to Universal Cells except for information on the list specifically regarding the disputed Target.  Adaptimmune shall notify
the  JRC  whether  a  nominated  Target  is  an  Excluded  Target  within  [***]  after  such  Target  is  nominated.   Any  notice  from
Adaptimmune stating that a nominated Target is an Excluded Target shall include information regarding the basis upon which
such nominated Target is an Excluded Target (e.g., because such Target is the subject of an Active Research Program or a
Third Party License or term sheet negotiations therefor), and a statement as to whether Adaptimmune is willing nevertheless to
allow  such  Excluded  Target  to  be  designated  as  a  Collaboration  Target  or  a  Universal  Cells  Program  Target,  as  applicable
(“Excluded  Target  Clearance”).    If  Adaptimmune  notifies  the  JRC  that  such  Target  is  not  an  Excluded  Target,  or  if
Adaptimmune notifies the JRC that such Target is an Excluded Target but nevertheless provides Excluded Target Clearance,
then such nominated Target shall remain eligible for designation as a Collaboration Target or Universal Cells Program Target
(as applicable) unless Burdened Technology Limitations apply and no Burdened Technology Clearance is obtained as set forth
in  Section  3.3.3(b)  (Notice  Obligations).    However,  if  Adaptimmune  notifies  the  JRC  that  the  nominated  Target  is  an
Excluded  Target,  and  Adaptimmune  does  not  provide  an  Excluded  Target  Clearance  within  [***]  days  of  notification  of
nomination of such Target for designation, then such Target may not be designated as a Collaboration Target or a Universal
Cells Program Target (as applicable) and in lieu of such previously nominated Excluded Target, the JRC

31

(with respect to the nomination of a Target for designation as a Collaboration Target) or Universal Cells (with respect to the
nomination  of  a  Target  for  designation  as  a  Universal  Cells  Program  Target)  may  nominate  an  alternative  Target  for
designation  as  a  Collaboration  Target  or  Universal  Cells  Program  Target  (as  applicable)  as  described  in  this  Section  3.3
(Designation of Nominated Targets).

3.3.2    Acceptance of Burdened Technology .  If Adaptimmune does not provide written notice to the JSC
(with respect to a Target nominated for designation as a Collaboration Target) or to Universal Cells (with respect to a Target
nominated  for  designation  as  a  Universal  Cells  Program  Target)  that  such  nominated  Target  is  an  Excluded  Target,  or  if
Adaptimmune provides Excluded Target Clearance notwithstanding the fact that such Target is an Excluded Target, then such
Target shall become so designated as a Collaboration Target or Universal Cells Program Target (as applicable) once the JSC
(as  to  a  proposed  Collaboration  Target)  or  Universal  Cells  (as  to  a  proposed  Universal  Cells  Program  Target)  accepts  any
Burdened Technology Limitations with respect to such Target as set forth in Section 3.3.3 (Burdened Technology Limitations)
below.

3.3.3    Burdened Technology Limitations.

( a )        Burdened Technology Limitations.  The Parties acknowledge that certain materials and data

Technology may include financial or other obligations to Third Parties (“Burdened Technology”).  Accordingly, the use of
such  Burdened  Technology  in  a  Collaboration  Research  Program,  Collaboration  Profit-Share  Program  or  Universal  Cells
Program  (as  applicable),  or  the  Development,  Manufacture,  Medical  Affairs  Activities,  or  Commercialization  of  products
resulting from the use of such Burdened Technology, may result in (i) financial or obligations to Third Parties relating to the
practice  of  such  Burdened  Technology,  (ii)  limitations  on  the  use  of  certain  information  contained  in  the  Burdened
Technology, or (iii) a reduction in the rights of the Parties under this Agreement under the Burdened Technology relative to
their rights under other technology licensed to such Party pursuant to this Agreement (the obligations and limitations set forth
in the foregoing clauses ((i) through (iii)), the “Burdened Technology Limitations”).

( b )        Notice  Obligations.    Each  Party  will  inform  the  other  Party  of  any  Burdened  Technology
Limitations  relating  to  any Adaptimmune  Technology  or  Universal  Cells  Technology  that  it  may  Control  in  relation  to  any
Target nominated for designation as a Collaboration Target or Universal Cells Program Target no later than [***] after it is
determined  pursuant  to  Section  3.3.1  (Excluded  Targets)  whether  such  Target  remains  eligible  for  such  designation.    Such
Target will be designated as a Collaboration Target or Universal Cells Program Target (as applicable) if, after evaluation of
the nature and scope of the Burdened Technology Limitations, the JSC (with respect to a Target nominated for designation as
a Collaboration Target) or Universal Cells (with respect to a Target nominated for designation as a Universal Cells Program
Target) approves such Burdened Technology Limitations (“Burdened Technology Clearance”).

designated, effective as of the expiration of the [***] time period in

(c)        If no Burdened Technology Limitations apply to a nominated Target, then such Target will be

32

Section  3.3.3(b)  (Notice  Obligations),  as  a  Collaboration  Target  or  a  Universal  Cells  Program  Product,  as  application.    If
Burdened  Technology  Limitations  apply,  but  no  Burdened  Technology  Clearance  is  obtained  within  such  [***]  day  time
period, then the JRC (with respect to the nomination of a Target for designation as a Collaboration Target) or Universal Cells
(with respect to the nomination of a Target for designation as a Universal Cells Program Target) may nominate an alternative
Target for designation as a Collaboration Target or Universal Cells Program Target (as applicable) as described in this Section
3.3 (Designation of Nominated Targets).

3.3.4    Target Maximums. A maximum of three (3) distinct Collaboration Targets may be designated ([***]).

A maximum of two distinct (2) Universal Cells Program Targets may be designated.

3.3.5        Designation  Exclusivity.    Once  a  Target  is  designated  as  a  Collaboration  Target,  it  cannot  also  be
designated  as  a  Universal  Cells  Program  Target,  and  once  a  Target  is  designated  as  a  Universal  Cells  Program  Target,  it
cannot also be designated as a Collaboration Target.

3.3.6    Dispute as to Excluded Targets.  If Universal Cells’ members of the JSC disagree with, or otherwise
question, Adaptimmune’s notice that a Target nominated for designation as a Collaboration Target or Universal Cells Program
Target under this Section 3.3 (Designation of Nominated Targets) is an Excluded Target, then such members may request that,
subject  to  any  confidentiality  obligations  to  any  Third  Parties,  Adaptimmune  provide  further  information  to  support  its
position that the nominated Target is an Excluded Target.  If, within [***] after the JSC’s receipt of such further information,
Universal Cells’ members of the JSC still disagree or question in good faith whether such Target is an Excluded Target, then
the Parties shall engage a mutually acceptable Expert to determine whether the nominated Target is an Excluded Target.  The
Expert shall enter into confidentiality agreement with both Parties and shall render his or her decision within [***] after being
engaged after reviewing information from Adaptimmune supporting its determination that a nominated Target is an Excluded
Target.  Subject to any confidentiality obligations to any Third Parties, each Party shall reasonably cooperate with the Expert
to  provide  to  him  or  her  reasonable  additional  information  requested  by  the  Expert  to  determine  whether  such  Target  is  an
Excluded  Target.    If  the  Expert  finds  that  the  nominated  Target  is  an  Excluded  Target,  then  Universal  Cells  shall  be
responsible for all costs and expenses of appointing the Expert and such Target shall not become a Collaboration Target or a
Universal  Cells  Program  Target  and  the  JRC  or  Universal  Cells,  as  applicable,  may  nominate  alternative  Targets  to  be
nominated for designation as a Collaboration Target or a Universal Cells Program Target, as applicable.  If the Expert finds
that  the  nominated  Target  is  not  an  Excluded  Target,  then Adaptimmune  shall  be  responsible  for  all  costs  and  expenses  of
appointing the Expert and such Target shall become a Collaboration Target or a Universal Cells Program Target as applicable.

3.4       [***].

3.5       Contributed Technology.    Prior to contributing Universal Cells Background IP for use in a Collaboration
Product,  [***]  (“Contributed  Technology”),  Universal  Cells  will  disclose  to Adaptimmune  in  writing  (the  “Contributed
Technology Notice”) the details of such Universal Cells Background IP it proposes to use for such Collaboration Product, as
well as whether an exclusive Elected Unilateral Adaptimmune Product License would be available if such

33

Collaboration Product were to become a Unilateral Adaptimmune Product, and if not, provide a description of any basis for it
not being then available (e.g., certain rights have been licensed out in a manner precluding the grant of the exclusive Elected
Unilateral Adaptimmune Product License) (a “Universal Cells Impediment”). [***].

ARTICLE 4

COLLABORATION RESEARCH PROGRAM

4.1       Collaboration Research Plans.   Within [***] after the designation of a Collaboration Target (either pursuant
to an initial designation pursuant to Article 3 (Pre-Designation Research Program), including in the exercise of the Additional
Collaboration Target Right, or a designation in connection with a Target Substitution Right conducted pursuant to Section 4.6
(Target Substitution)), the JRC, in consultation with the JDC if it then exists, shall prepare and send to the JSC for approval a
Collaboration  Research  Plan  for  the  Collaboration  Research  Program  for  such  Collaboration  Target.    Each  Collaboration
Research Plan shall include details for the Development activities (non-clinical, pre-clinical, and clinical) to be conducted by
the Parties from designation of the relevant Target until the end of the first Phase 1 Clinical Trial for a Collaboration Product
Directed To such Target, including, as may be applicable, (a) characterization work in relation to such Collaboration Target,
(b)  any  other  nonclinical  or  pre-clinical  Development  activities  to  be  conducted  with  respect  to  Collaboration  Products
Directed To such Collaboration Target, (c) requirements for a “successful” Phase 1 Clinical Trial for Collaboration Products
Developed under such Collaboration Research Plan demonstrating that Development of such Collaboration Product should be
further progressed (for each Collaboration Research Plan, the “Phase 1 Success Criteria”) and other criteria agreed upon by
the JDC pursuant to Section 4.2 (Collaboration Research Program Parameters), and (d) a budget for the costs and expenses of
activities  to  be  incurred  in  connection  with  the  conduct  of  activities  under  the  Collaboration  Research  Plan  (the
“Collaboration Research Plan Budget”).  Each Collaboration Research Plan shall be updated from time to time as agreed by
the JRC in consultation with JDC, but in any event at least once per Calendar Year.

4.2       Collaboration Research Program Parameters.   With respect to each Collaboration Research Program, the
JRC, in consultation with the JDC, shall discuss [***].  For each Collaboration Research Program, the JRC, in consultation
with the JDC, shall adopt project progression guidelines, including lead selection for the Collaboration Products Developed
under such Collaboration Research Program.  Additionally, the JRC, in consultation with the JDC, shall discuss and agree on
completion  requirements  for  each  stage  of  the  Development  activities  to  be  conducted  pursuant  to  each  Collaboration
Research Program for the Collaboration Products that are Developed under such Collaboration Research Program, including
go/no-go  criteria  for  advancing  a  Collaboration  Product  into  a  Phase  1  Clinical  Trial.    The  JDC  shall  update  the  applicable
Collaboration Research Plan accordingly with such agreed-upon criteria.

4.3       Conduct of Collaboration Research Program.    Each Party shall use Commercially Reasonable Efforts to
conduct the activities for each Collaboration Research Program that are assigned to it under the Collaboration Research Plan
for such Collaboration Research Program in accordance with the timeframes for completion of such activities set forth in such
plan.  The Parties acknowledge and agree that neither Party guarantees the success of tasks

34

 
undertaken under a Collaboration Research Program.  The Parties intend that they will Develop one Collaboration Product for
each  Collaboration  Target;  provided  that  the  Parties  may  agree  to  modify  and  improve  such  Collaboration  Product  in
connection with the Development thereof.

4.4       Conduct of Phase 1 Clinical Trial for Collaboration Product.   Unless the JSC agrees otherwise, [***] shall
lead  the  conduct  of  and  shall  be  the  sponsor  for  any  Phase  1  Clinical  Trial  for  a  Collaboration  Product  pursuant  to  a
Collaboration  Research  Program,  including  all  related  IND  submissions  and  regulatory  communications  in  connection
therewith.  Adaptimmune will provide regular updates to [***] regarding the conduct of any such Phase 1 Clinical Trial for a
Collaboration Product and, through the JDC, will review and discuss the protocol for any such Phase 1 Clinical Trial and any
material amendments thereto.  In addition, [***] will provide to [***] for review all substantive regulatory submissions and
correspondence related to any such Phase 1 Clinical Trial prior to submission thereof and will consider all timely comments
[***] thereon in good faith.  To the extent permitted by the applicable Regulatory Authority, one representative of [***] may
attend and participate in meetings with Regulatory Authorities in the Territory directly relating to the conduct of any Phase 1
Clinical Trial for a Collaboration Product.  Upon completion of the first Phase 1 Clinical Trial conducted for a Collaboration
Product  led  and  sponsored  by  [***],  the  JDC  shall  coordinate  the  process  for  transferring  promptly  the  ownership  and
sponsorship of the relevant IND to [***], with such process to be completed within [***] after the issuance of the final study
report  from  such  Phase  1  Clinical  Trial.    Each  Party  shall  have  a  right  of  reference  to  all  regulatory  submissions  made  for
Collaboration  Products  to  the  extent  relating  to  the  Adaptimmune  Technology  (for  Adaptimmune)  or  the  Universal  Cells
Technology (for Universal Cells).

4.5       Collaboration Research Program Costs.   Universal Cells shall be responsible for the costs and expenses of
the conduct of all activities under each Collaboration Research Program for the Collaboration Products thereunder (regardless
of whether such activities are to be conducted by Universal Cells or Adaptimmune), including Development activities such as
the  conduct  of  a  Phase  1  Clinical  Trial  for  Collaboration  Products  to  be  conducted  under  such  Collaboration  Research
Program and Manufacturing activities to supply Collaboration Products for use in such Collaboration Research Program.  The
anticipated  costs  and  expenses  of  such  activities  shall  be  set  forth  in  the  Collaboration  Research  Plan  Budget  for  each
Collaboration  Research  Plan,  which  budget  will  be  updated  as  necessary  in  connection  with  any  update  to  the  applicable
Collaboration  Research  Plan.    If  the  Collaboration  Research  Plan  is  updated  to  require Adaptimmune  to  perform  additional
Development activities, but the JSC does not approve a corresponding increase in the Collaboration Research Budget to reflect
the performance of such additional activities, then Adaptimmune will not be required to perform any additional activities in
the updated Collaboration Research Plan to the extent that performance of such activities would exceed the amount budgeted
for  the  performance  of  such  activities  in  the  then-current  Collaboration  Research  Budget.    If,  during  any  Calendar  Year,
Adaptimmune incurs more than [***] of the amount included in the then-current Collaboration Research Plan Budget for such
Calendar Year, then unless otherwise approved by the JSC or such amounts are incurred as a result of Universal Cells’ failure
to perform any of its obligations under this Agreement, Universal Cells shall have no obligation to reimburse Adaptimmune
for any such excess amounts.  Furthermore, unless otherwise agreed by the JRC, in no event will the amount to be incurred
pursuant to the Collaboration Research Plan Budget exceed in the aggregate [***] in total on a per Collaboration Target basis
for activities conducted by the Parties pursuant to the Collaboration Research Plan

35

 
during any Calendar Year, exclusive of the costs of the conduct of any Phase 1 Clinical Trial for a Collaboration Product.  In
accordance  with  a  procedure  to  be  agreed  by  the  JRC  in  connection  with  development  and  approval  of  the  Collaboration
Research  Plan  and  Collaboration  Research  Budget  for  each  Collaboration  Research  Program,  no  less  frequently  than  each
Calendar  Quarter,  Universal  Cells  shall  reimburse  all  of Adaptimmune’s  costs  and  expenses  on  an  FTE  Cost  plus  Out  of
Pocket Cost basis incurred for activities conducted pursuant to each Collaboration Research Plan to the extent consistent with
this Section 4.5 (Collaboration Research Program Costs).  The allocation between the Parties of costs and expenses incurred to
Develop Collaboration Products beyond activities set forth in the applicable Collaboration Research Plan for the Collaboration
Target that such Collaboration Products are Directed To are set forth in Article 5 (Co-Development of Collaboration Profit-
Share Products).

4.6       Target Substitution.

4.6.1    Pre-IND Substitutions for Collaboration Targets or Universal Cells Program Targets.  Prior to the
submission  of  the  first  IND  for  a  Collaboration  Product  Directed  To  a  Collaboration  Target  or  a  Universal  Cells  Program
Product Directed To a Universal Cells Program Target (as applicable), the JRC, in consultation with the JDC (with respect to a
Collaboration  Target)  or  Universal  Cells  (with  respect  to  a  Universal  Cells  Program  Target),  as  applicable,  may  elect  to
nominate  a  substitute  Target  to  replace  such  then-designated  Collaboration  Target  or  Universal  Cells  Program  Target  (as
applicable)  (a  “Collaboration  Substitution  Target”  with  respect  to  a  Collaboration  Target  or  a  “Universal  Cells
Substitution Target” with respect to a Universal Cells Program Target).  In such case, Section 3.2 (Nomination) and Section
3.3  (Designation  of  Nominated  Targets)  above  shall  apply mutatis  mutandis  to  the  nomination  and  designation  of  such
Substitution Target to replace the then-designated Collaboration Target or Universal Cells Program Target, as applicable (the
“Target Substitution Right”) and a new Collaboration Research Program will be initiated in accordance with the terms of
this Agreement.  For clarity, once such Substitution Target is designated as the replacement Collaboration Target or Universal
Cells  Program  Target  (as  applicable),  such  replaced  Target  shall  no  longer  be  a  Collaboration  Target  or  Universal  Cells
Program  Target,  as  applicable.    The  JSC  (with  respect  to  replacement  of  a  Collaboration  Target)  may  elect  to  exercise  its
Target  Substitution  Right  up  to  [***]  for  each  Collaboration  Target  (other  than  any  Collaboration  Target  designated  under
Section 3.4 (Additional Collaboration Target Right), for which Collaboration Target the Target Substitution Right will only be
available [***]) (i.e.,  for  a  total  of  up  to  [***]  for  Collaboration  Targets,  [***]  substitutions  being  possible  for  each  of  the
[***] initially designated Collaboration Targets and [***] substitution being possible for the Collaboration Target designated
if the Additional Collaboration Target Designation Right applies).  Universal Cells (with respect to replacement of a Universal
Cells Program Target) may elect to exercise its Target Substitution Right up to [***] times for each Universal Cells Program
Target (i.e., for a total of [***] substitutions for Universal Cells Program Targets, [***] substitutions being possible for each
of  the  up  to  the  [***]  initially  designated  Universal  Cells  Program  Targets).    The  JSC  may  decide  to  make  any  additional
Target substitutions with respect to any Collaboration Target or Universal Cells Program Target (as applicable) for which the
Target  Substitution  Right  has  already  been  exhausted  under  this  Section  4.6.1  (Pre-IND  Substitutions  for  Collaboration
Targets or Universal Cells Program Targets), but any such additional Target substitutions may be made only upon the mutual
written agreement of the Parties (and not by decision of the JSC).

36

4.6.2        Phase  1  Clinical  Trial  Substitution  Right  for  Collaboration  Targets.   After  the  completion  of  a
Phase 1 Clinical Trial for a Collaboration Product Directed To a Collaboration Target, if the data resulting from such Phase 1
Clinical Trial indicates that such Collaboration Product does not meet the applicable Phase 1 Success Criteria, then, unless the
Collaboration  Target  that  such  Collaboration  Product  is  Directed  To  was  designated  as  a  Collaboration  Product  pursuant
Section  3.4  (Additional  Collaboration  Target  Right),  the  JRC,  in  consultation  with  the  JDC  shall  have  [***]  Target
Substitution  Right  to  nominate  to  the  JSC  for  approval  a  Collaboration  Substitution  Target  to  replace  such  Collaboration
Target that such Collaboration Product was Directed To.  In such case, Section 3.2 (Nomination) and Section 3.3 (Designation
of Nominated Targets) above shall apply mutatis mutandis to the nomination and designation of such Substitution Target and a
new Collaboration Research Program will be initiated in accordance with the terms of this Agreement.  The JSC shall have
until  the  date  that  is  [***]  days  after  the  date  that  the  Tables,  Figures,  and  Listings  from  such  Phase  1  Clinical  Trial  first
become available to so notify the JRC of such substitution.

4.6.3    Effect of Substitution.  For clarity, once a Collaboration Substitution Target is designated as the new
Collaboration  Target  and  replaces  the  previously-designated  Target  pursuant  to  Section  4.6.1  (Pre-IND  Substitution  for
Collaboration  Targets  or  Universal  Cells  Program  Targets)  or  Section  4.6.2  (Phase  1  Clinical  Trial  Substitution  Right  for
Collaboration Targets), (a) such replaced Target shall no longer be a Collaboration Target and will instead be a Lapsed Target,
and (b) notwithstanding any other provision to the contrary set forth in this Agreement, the Parties will have the right to begin
a new Collaboration Research Program for such Collaboration Substitution Target, and such Collaboration Research Program
will replace the Collaboration Research Program for the replaced Collaboration Target.

4.7       Progress Updates.   At  each  meeting  of  the  JRC  (with  respect  to  nonclinical  and  pre-clinical  Development
activities) and of the JDC (with respect to Development activities relating to any clinical trials for a Collaboration Product,
including each Phase 1 Clinical Trial), each Party will share with the JRC or JDC (as applicable) a summary regarding the
activities  conducted  by  or  on  behalf  of  such  Party  under  each  Collaboration  Research  Program  since  the  last  JRC  or  JDC
meeting,  sufficient  for  the  JRC  or  JDC  to  assess  each  Party’s  progress  under  each  Collaboration  Research  Program.    Each
Party will also promptly provide notice to the other Party, through the JRC or JDC, of any significant Development events
under each Collaboration Research Program that the reporting Party reasonably believes materially impacts the Development
activities of the other Party under such Collaboration Research Program or otherwise under this Agreement or that such Party
reasonably believes would be of interest to the other Party.

4.8       Collaboration Research Program Records.  Each Party shall require that all work conducted by or on behalf
of each Party in the course of a Collaboration Research Program be completely and accurately recorded, in sufficient detail
and in good scientific manner, in separate laboratory notebooks.  On reasonable notice, and at reasonable intervals, each Party
shall  have  the  right  to  inspect  and  copy  all  such  records  of  the  other  Party  reflecting  work  done  under  the  Collaboration
Research Program, to the extent reasonably required to carry out its respective obligations and to exercise its respective rights
hereunder.    Notwithstanding  the  definition  of  “Confidential  Information,”  all  such  records  shall  constitute  Confidential
Information of the Party creating such records.

37

4.9       End of Collaboration Research Program.   Unless otherwise agreed by the Parties and subject to the JSC’s
exercise  of  the  [***]  Target  Substitution  Right  pursuant  to  Section  4.6.2  (Phase  1  Clinical  Trial  Substitution  Right  for
Collaboration Targets) if the Collaboration Product that was the subject of a Collaboration Research Program did not meet the
Phase 1 Success Criteria set forth in the Collaboration Research Plan for such Collaboration Research Program, then after the
completion  of  the  first  Phase  1  Clinical  Trial  for  a  Collaboration  Product  that  is  the  subject  of  a  Collaboration  Research
Program, the Collaboration Research Term for such Collaboration Research Program will expire and no further activities will
be conducted in furtherance of such Collaboration Research Program.

4.10     Ongoing Development/Commercialization.

4.10.1    Continuing  Development  and  Commercialization  Notice.    Promptly  after  the  Tables,  Figures,  and
Listings  from  the  first  Phase  1  Clinical  Trial  for  a  Collaboration  Product  become  available  to  the  sponsoring  Party  and  are
provided to the non-sponsoring Party (the later of such dates, the “Phase 1 Data Availability Date ”), the Parties, through the
JDC,  shall  meet  and  discuss  the  results  thereof.    No  later  than  [***]  after  the  Phase  1  Data  Availability  Date  for  a
Collaboration Product, each Party shall notify the other Party in writing of whether such Party is interested in continuing to
Develop, Manufacture, and Commercialize such Collaboration Product in the Territory pursuant to this Agreement (for each
Collaboration Research Program, a “Continuing Development and Commercialization Notice”).

4.10.2    Collaboration  Profit-Share  Products  and  Targets.    If,  with  respect  to  a  Collaboration  Research
Program,  both  Universal  Cells  and  Adaptimmune  each  provide  the  other  Party  a  Continuing  Development  and
Commercialization  Notice  within  the  [***]  day  time  period  noted  in  Section  4.10.1  (Continuing  Development  and
Commercialization  Notice),  then  the  Collaboration  Target  that  is  the  subject  of  such  Collaboration  Research  Program  shall
immediately become a Collaboration Profit-Share Target, and the Collaboration Product that was the subject of such Phase 1
Clinical Trial shall immediately become deemed a Collaboration Profit-Share Product.

4.10.3  Unilateral Products and Targets.

( a )        Unilateral Universal Cells Product.  If, with respect to a Collaboration Research Program,
Universal Cells provides Adaptimmune with a Continuing Development and Commercialization Notice within the [***] day
time  period  noted  in  Section  4.10.1  (Continuing  Development  and  Commercialization  Notice),  but  either  (i) Adaptimmune
provides  Universal  Cells  written  notice  that  Adaptimmune  does  not  wish  to  continue  to  Develop,  Manufacture,  and
Commercialize  the  Collaboration  Product  Directed  To  the  Collaboration  Target  that  is  the  subject  of  such  Collaboration
Research  Program  or  (ii)  Adaptimmune  does  not  timely  provide  Universal  Cells  with  a  Continuing  Development  and
Commercialization  Notice  within  the  [***]  day  time  period  noted  in  Section  4.10.1  (Continuing  Development  and
Commercialization  Notice),  then  (i)  the  Collaboration  Target  that  such  Collaboration  Product  was  Directed  To  shall
immediately  become  a  Unilateral  Universal  Cells  Target  and  cease  to  be  a  Collaboration  Target  and  (ii)  the  Collaboration
Product that was the subject of such Phase 1 Clinical Trial shall immediately become a Unilateral Universal Cells Product and
cease to be a Collaboration Product.

38

( b )        Unilateral Adaptimmune Product.    If,  with  respect  to  a  Collaboration  Research  Program,
Adaptimmune provides Universal Cells with a Continuing Development and Commercialization Notice within the [***] day
time period noted in Section 4.10.1 (Continuing Development and Commercialization Notice), but either (i) Universal Cells
provides  Adaptimmune  written  notice  that  Universal  Cells  does  not  wish  to  continue  to  Develop,  Manufacture,  and
Commercialize  the  Collaboration  Product  Directed  To  the  Collaboration  Target  that  is  the  subject  of  such  Collaboration
Research  Program  or  (ii)  Universal  Cells  does  not  timely  provide  Adaptimmune  with  a  Continuing  Development  and
Commercialization  Notice  within  the  [***]  day  time  period  noted  in  Section  4.10.1  (Continuing  Development  and
Commercialization  Notice),  then  (i)  the  Collaboration  Target  that  such  Collaboration  Product  was  Directed  To  shall
immediately  become  a  Unilateral  Adaptimmune  Target  and  cease  to  be  a  Collaboration  Target  and  (ii)  the  Collaboration
Product that was the subject of such Phase 1 Clinical Trial shall immediately become a Unilateral Adaptimmune Product and
cease to be a Collaboration Product.

4.10.4    Lapsed  Products  and  Targets.    If,  with  respect  to  a  Collaboration  Research  Program,  neither  Party
provides  the  other  Party  with  a  Continuing  Development  and  Commercialization  Notice  within  the  [***]  day  time  period
noted in Section 4.10.1 (Continuing Development and Commercialization Notice), or if each Party notifies the other Party in
writing that it does not wish to continue to Develop, Manufacture, and Commercialize Collaboration Products Directed To the
Collaboration  Target  that  is  the  subject  of  such  Collaboration  Research  Program,  then  (a)  such  Collaboration  Target  shall
immediately become a “Lapsed Target” and cease to be a Collaboration Target and (b) all Collaboration Products Directed
To such Collaboration Target shall immediately become Lapsed Products and cease to be Collaboration Products.

4.10.5  Technology Transfer.   In the event that a  Collaboration  Target  becomes  a  Unilateral  Target  and  the
applicable Collaboration Product becomes a Unilateral Product under Sections 4.10.3 (Unilateral Products and Targets) or 5.3
(Development  of  and  Clinical  Trials  for  Collaboration  Profit-Share  Products),  the  Party  relinquishing  its  right  to  such

Manufacture,  and  Commercialize  such  Unilateral  Product,  except  for  such  material  Know-How  already  in  the  receiving
Party’s possession.  If so requested, the transferring Party agrees to provide reasonable technical assistance to the other Party,
at the transferring party’s expense, to enable the other Party to reasonably understand and utilize the transferred Know-How.

CO-DEVELOPMENT OF COLLABORATION PROFIT-SHARE PRODUCTS

ARTICLE 5

5.1       Co-Development Plans.   Within [***] days after the date a Collaboration Product that was the subject of the
Phase 1 Clinical Trial under the applicable Collaboration Research Plan is designated as a Collaboration Profit-Share Product
pursuant to Section 4.10.2 (Collaboration Profit-Share Products and Targets), the JDC shall prepare and send to the JSC for
approval  the  Co-Development  Plan  for  such  Collaboration  Profit-Share  Product,  including  (a)  an  allocation  between  the
Parties of responsibilities for Development activities for the applicable Collaboration

39

 
Profit-Share Product, (b) a timeline and plan for process development, chemistry, manufacturing, and controls activities and
production with respect to the relevant Collaboration Profit-Share Product to be Developed under each Co-Development Plan,
and (c) a budget of all costs and expenses to be incurred in the performance of activities under the applicable Co-Development
Plan (each, a “Co-Development Budget”).  Each Co-Development Plan shall be updated from time to time as agreed by the
JDC but in any event at least once per Calendar Year.

5.2       Conduct of Co-Development Programs.   Each Party shall use Commercially Reasonable Efforts to conduct
the  activities  for  each  Co-Development  Program  that  are  assigned  to  it  under  the  Co-Development  Plan  for  such  Co-
Development Program in accordance with the timeframes for completion of such activities set forth in such plan.  The Parties
acknowledge and agree that neither Party guarantees the success of tasks undertaken under a Co-Development Program.

5.3              Development  of  and  Clinical  Trials  for  Collaboration  Profit-Share  Products.     [***]  shall  lead  all
Development Efforts for the Collaboration Profit-Share Products, including the conduct of (and shall be sponsor of) all clinical
trials to be conducted for the Collaboration Profit-Share Products pursuant to each Co-Development Plan, including managing
and  owning  all  related  INDs  and  other  regulatory  submissions  and  communications  in  connection  therewith,  and  all
Regulatory Approvals, unless the JSC agrees to delegate to [***] the responsibility to conduct clinical trials, in which case the
relevant  Co-Development  Plan  shall  specify  each  Party’s  roles  in  such  clinical  trials  for  such  Collaboration  Profit-Share
Product.  The  Parties  shall  reasonably  cooperate  in  connection  with  the  conduct  of  all  such  Development  activities  and  will
negotiate in good faith to enter into pharmacovigilance agreements and quality assurance agreements before for the conduct of
any  Development  activities  for  a  Collaboration  Profit-Share  Product  under  a  Co-Development  Plan.  At  any  time  (A)  if,
following escalation pursuant to Section 2.2.4(b) (Escalation), the JSC and the Executive Officers are unable to agree on a Co-
Development  Plan  or  Co-Development  Budget  for  a  Collaboration  Profit-Share  Product,  or  any  update  thereto,  or  (B)
following  completion  of  a  clinical  trial  under  a  Co-Development  Plan,  [***],  in  its  sole  discretion,  may  deliver  a  notice  to
[***] electing to opt-out of further Development of the applicable Collaboration Profit-Share Product under this Agreement
(an “Opt-Out Notice”).  Upon receipt of an Opt-Out Notice, [***] may elect to either (i) continue to Develop, Manufacture,
and Commercialize such Collaboration Profit-Share Product as a Unilateral [***] Product, in which case, the Collaboration
Profit-Share Target that such product was Directed To will thereafter become a Unilateral [***] Target for purposes of this
Agreement or (ii) to terminate the further  Development,  Manufacture,  and  Commercialization  of  such  Collaboration  Profit-
Share Product, in which case the Collaboration Profit-Share Target that such product was Directed To will thereafter become a
Lapsed Target for purposes of this Agreement.  [***] will provide written notice to [***] of its election under the foregoing
clause (i) or (ii) no later than [***] days after the date of the applicable Opt-Out Notice, and if [***] does not provide to [***]
notice  of  such  election  prior  to  the  end  of  such  [***]  day  period  the  applicable  Collaboration  Profit-Share  Target  will
thereafter become a Lapsed Target for purposes of this Agreement.

5.4       Regulatory.  All MAAs for the Collaboration Products (including Collaboration Profit-Share Products) shall
be made by and in the name of Universal Cells or its Affiliate or sublicensee and all Regulatory Approval will be held in the
name  of  Universal  Cells  or  its Affiliate  or  sublicensee,  in  consultation  with Adaptimmune  through  the  JDC.    In  addition,
unless otherwise

40

agreed by the JDC, all filings, submissions to, and correspondence with Regulatory Authorities regarding Regulatory Approval
for any Collaboration Profit-Share Product shall be made by Universal Cells in consultation with Adaptimmune through the
JDC.    Universal  Cells  shall  provide  to Adaptimmune  for  review  all  substantive  regulatory  submissions  and  correspondence
related to any Collaboration Profit-Share Product and will consider all timely comments from Adaptimmune thereon in good
faith.  To the extent permitted by the applicable Regulatory Authority, one representative of Adaptimmune may attend, as an
observer,  meetings  with  Regulatory  Authorities  in  the  Territory  directly  relating  to  any  Collaboration  Profit-Share
Product.  Adaptimmune shall reasonably cooperate with Universal Cells in connection with all such regulatory activities for
the Collaboration Profit-Share Products.

5.5       Development Updates.  At each meeting of the JDC, each Party will share with the JDC (as applicable) a
summary regarding the activities conducted by or on behalf of such Party under each Co-Development Program since the last
JDC meeting, sufficient for the JDC to assess each Party’s Progress under the under the applicable plan.  Each Party will also
promptly  provide  notice  to  the  other  Party,  through  the  JDC,  of  any  significant  Development  events  under  the  Co-
Development Program that the reporting Party reasonably believes materially impacts the Development activities of the other
Party under such Co-Development Program or otherwise under this Agreement or that such Party reasonably believes would
be of interest to the other Party.

5.6       Development Costs.  The Parties will equally share Development Costs (as defined in Schedule 11.3) incurred
in the Development of Collaboration Profit-Share Products under each Co-Development Program.  Schedule 11.3 specifies the

ARTICLE 6

CO-COMMERCIALIZATION OF COLLABORATION PROFIT-SHARE PRODUCTS

6.1       Overview.  The Parties, through the JCC, will collaborate to develop the Commercialization strategy for all
Collaboration  Profit-Share  Products  and  otherwise  to  Commercialize  the  Collaboration  Profit-Share  Products  in  accordance
with  the  applicable  Co-Commercialization  Plan,  including  the  applicable  Co-Commercialization  Budget.    [***]  will  be
responsible for Commercialization of Collaboration Profit-Share Products in the Territory in accordance with the applicable
Co-Commercialization  Plan,  including  distribution,  sales,  reporting  to  Regulatory Authorities,  pricing  and  health  systems-
related activities, and all other Commercialization activities, provided, however, [***].  For each Collaboration Profit-Share
Product,  the  Parties  agree  to  negotiate  in  good  faith  a  Commercialization Agreement.   Adaptimmune  may  also  propose  to
Universal  Cells  that Adaptimmune  provide  such  Commercialization  support  in  major  EU  Countries  in  which  case  the  JCC
shall  discuss  such  proposal  in  good  faith.    Universal  Cells  shall  book  all  revenues  from  sales  of  Collaboration  Profit-Share
Products, subject to its obligations to share Profits with Adaptimmune as provided in Section 11.3 (Collaboration Profit-Share

Agreement becomes the subject of a Third Party’s claim or assertion of infringement of Patent Rights owned or controlled by
such  Third  Party,  then  the  Party  first  having  notice  of  the  claim  or  assertion  shall  promptly  notify  the  other  Party,  and  the
Parties  shall  promptly  confer  to  consider  the  claim  or  assertion  and  the  appropriate  course  of  action.  Unless  the  Parties
otherwise  agree  in  writing,  each  Party  shall  have  the  right  to  defend  itself  against  a  suit  that  names  it  as  a  defendant  (the
“Defending Party”). Neither Party shall enter into any settlement of any claim described in this Section 9.10.1 (Collaboration
Profit-Share Products) that admits to the invalidity or unenforceability of any Patent Right Controlled by the other Party (or
otherwise  affects  the  scope,  validity  or  enforceability  of  such  Patent  Right),  incurs  any  financial  liability  on  the  part  of  the
other Party or requires an admission of liability, wrongdoing or fault on the part of the other Party without such other Party’s
written consent. In any event, the other Party shall reasonably assist the Defending Party and cooperate in any such litigation
at the Defending Party’s request and expense. Additionally, if the Defending Party is not the Party that Controls the Patent
Right in question, then the other Party shall have the right to join any such action using counsel of its choice, at such Party’s
sole expense (provided that if such action involves Collaboration Products, then if such action arises during the time period in
which such Collaboration Product is a Collaboration Profit-Share Product, such costs will be included in the Program Costs
and the calculation of Profit pursuant to Schedule 11.3).

11.6     Records and Audits .  Each Party will keep complete and accurate records of payments required under this
Agreement for a period of [***] years after the end of the Calendar Year in which any such payment was due. Each Party will
have  the  right,  once  annually  at  its  own  expense,  to  have  a  nationally  recognized,  independent,  certified  public  accounting
firm,  selected  by  it  and  subject  to  the  other  Party’s  prior  written  consent  (which  shall  not  be  unreasonably  withheld,
conditioned or delayed), review any such records of the other Party and its Affiliates (the “Audited Party”) in the location(s)
where  such  records  are  maintained  by  the Audited  Party  upon  reasonable  written  notice  (which  shall  be  no  less  than  [***]
days’ prior written notice) and during regular business hours and under obligations of strict confidence, for the sole purpose of
verifying the basis and accuracy of payments made under this Agreement within [***] year period preceding the date of the
request for review. Each Party shall require its sublicensees to retain and provide to such Party all records of payments that
such Party would be required to keep as if sales of a given Product by such sublicensees were sales of Product by such Party,
to enable the other Party to audit such records pursuant to this Section 11.6. No Calendar Year will be subject to audit under
this Section 11.6 more than once. The Audited Party will receive a copy of each such report concurrently with receipt by the
non-Audited Party, and such accounting firm shall report to the Parties only whether or not such calculations are correct and
the amount of any discrepancy. No other information shall be shared. Each Party agrees to treat the results of any such review
of the other Party’s records under this Section 11.6 as Confidential Information of the other Party and subject to the terms of
Article 11 (Financial Provisions). Should such inspection lead to the discovery of a discrepancy to the non-Audited Party’s
detriment, the Audited Party will, within [***] days after receipt of such report from the accounting firm, pay any undisputed
amount of the discrepancy. Each Party requesting review under this Section 11.6 will pay the full cost of the review unless the
underpayment of amounts due to the non-Audited Party is greater than [***] of the amount due for the entire period being
examined,  in  which  case  the Audited  Party  will  pay  the  reasonable  cost  charged  by  such  accounting  firm  for  such  review.
Should the audit lead to the discovery of a discrepancy to the Audited Party’s detriment, the Audited Party may, at its option,
credit the amount of the discrepancy, without interest, against future payments payable to the non-Audited Party under this
Agreement, and if there are no such payments payable or if the Audited Party elects not to apply such credit, then non-Audited
Party  shall  pay  to  the  Audited  Party  the  amount  of  the  discrepancy,  plus  interest  in  accordance  with  Section  11.8  (Late
Payments), within thirty (30) days of non-Audited Party’s receipt of the report.

11.7     Currency Exchange.  With respect to Net Sales invoiced or expenses incurred in U.S. dollars, the Net Sales or
expense amounts and the amounts due to the receiving Party hereunder shall be expressed in U.S. dollars. With respect to Net
Sales invoiced or expenses incurred in a currency other than U.S. dollars, the Net Sales or expense shall be expressed in the
domestic currency of the entity making the sale or incurring the expense, together with the U.S. dollar equivalent, calculated
using the arithmetic average of the spot rates on the last business day of each month of the calendar quarter in which the Net
Sales  were  made  or  the  expense  was  incurred.  The  “closing  mid-point  rates”  found  in  the  “dollar  spot  forward  against  the
dollar” table published by the Financial Times or any other publication as agreed to by the Parties shall be used as the source
of spot rates to calculate the average as defined in the preceding sentence. All payments shall be made in U.S. dollars. If at any
time legal restrictions in any country in the Territory prevent the prompt remittance of any payments with respect to sales in
that country, the paying Party shall have the right and option to make such payments by depositing the amount thereof in local
currency to the receiving Party’s account in a bank or depository in such country.

63

11.8     Late Payments.  The paying Party shall pay interest to the receiving Party on the aggregate amount of any
payments that are not paid on or before the date such payments are due under this Agreement at a rate per annum equal to
[***], or the highest rate permitted by Applicable Law, calculated on the number of days such payments are paid after the date
such payments are due.

11.9     Taxes.

11.9.1  Withholding.  In the event that any Applicable Law requires the Party obligated to make a payment to
the other Party hereunder (“Paying Party”) to withhold taxes with respect to any payment to be made by the Paying Party
pursuant to this Agreement, the Paying Party (a) will notify the non-Paying Party of such withholding requirement prior to
making the payment to the non-Paying Party (such notice, which shall include the authority, basis and method of calculation
for  the  proposed  deduction  or  withholding,  shall  be  given  at  least  a  reasonable  period  of  time  before  such  deduction  or
withholding  is  required,  in  order  for  such  non-Paying  Party  to  obtain  reduction  of  or  relief  from  such  deduction  or
withholding), and (b) provide such assistance to the non-Paying Party, including the provision of such standard documentation
as may be required by a tax authority, as may be reasonably necessary in the non-Paying Party’s efforts to claim an exemption
from  or  reduction  of  such  taxes.    The  Paying  Party  will,  in  accordance  with  Applicable  Law,  withhold  taxes  from  such
payment, remit such taxes to the appropriate tax authority, and furnish the non-Paying Party with proof of payment of such
taxes within thirty (30) days following the payment.  If taxes are so withheld and paid to a tax authority, the Paying Party shall
provide reasonable assistance to the non-Paying Party to obtain a refund of taxes withheld, or obtain a credit with respect to
taxes paid.  If any taxes are so withheld and paid to the appropriate tax authority in accordance with this Section 11.9.1, such
withheld amounts shall be treated for all purposes of this Agreement as having been paid to the non-Paying Party.  The non-
Paying Party shall provide the Paying Party any tax forms (including Internal Revenue Service Forms W-9 or applicable W-8)
that may be reasonably necessary in order for the Paying Party to determine whether to withhold tax on any such payments or
to withhold tax on such payments at a reduced rate under Applicable Law, including any applicable bilateral income tax treaty.

11.9.2    Indirect  Taxes.   All  payments  due  to  the  non-Paying  Party  from  the  Paying  Party  pursuant  to  this
Agreement  shall  be  paid  exclusive  of  any  value-added  tax,  sales  tax,  consumption  taxes  and  other  similar  taxes  (“Indirect
Taxes”) (which, if applicable, shall be payable by the Paying Party upon receipt of a valid Indirect Tax invoice).  If the non-
Paying  Party  determines  that  it  is  required  to  report  any  such  tax,  the  Paying  Party  shall  promptly  provide  the  non-Paying
Party  with  applicable  receipts  and  other  documentation  necessary  or  appropriate  for  such  report.    For  clarity,  this  Section
11.9.2 is not intended to limit the Paying Party’s right to deduct value-added taxes in determining Net Sales.

CONFIDENTIALITY

12.1     Confidential Information.  A Party receiving Confidential Information from a disclosing Party will keep all of
the  disclosing  Party’s  Confidential  Information  in  confidence  with  the  same  degree  of  care  with  which  the  receiving  Party
holds its own Confidential Information

64

 
(but in no event less than a commercially reasonable degree of care). The receiving Party will not use the disclosing Party’s
Confidential  Information  except  in  connection  with  the  performance  of  its  obligations  and  exercise  of  its  rights  under  this
Agreement. The receiving Party may disclose the disclosing Party’s Confidential Information without the disclosing Party’s
prior written consent solely to the receiving Party’s Affiliates and their employees, subcontractors, consultants or agents who
have  a  need  to  know  such  Confidential  Information  in  order  to  perform  its  obligations  and  exercise  its  rights  under  this
Agreement and who are bound by restrictions on use and disclosure consistent with this Article 12 (Confidentiality) and to

How  pursuant  to  Section  9.7  (Ownership  of Arising  Inventions  and  Intellectual  Property  Rights)  will  be  deemed  to  be  the
discloser of such Confidential Information and the other Party will be deemed to the recipient thereof, and where the Parties
are  joint  owners  of  Confidential  Information,  each  Party  will  be  deemed  to  be  both  the  discloser  and  recipient  of  such
Confidential  Information.    Notwithstanding  the  foregoing,  clinical  and  nonclinical  data  generated  in  the  performance  of
clinical trials or nonclinical or pre-clinical studies of a Unilateral Product will belong to the Party who is responsible for such
Unilateral  Product  (i.e., Adaptimmune  for  Unilateral Adaptimmune  Products  and  Universal  Cells  for  Unilateral  Universal
Cells Products), and such Party will be deemed to be the discloser of such data and the other Party the recipient. The Parties
will  jointly  own,  and  each  Party  will  be  deemed  to  be  both  the  discloser  and  recipient  of,  clinical  and  nonclinical  data
generated in the performance of clinical trials or nonclinical or pre-clinical studies of Collaboration Products.

12.2     Exceptions.  The following information will not be Confidential Information for purposes of this Agreement

upon the Confidential Information as shown by written files or records.

12.3     Permitted Disclosure.  Notwithstanding the restrictions imposed in Section 12.2 (Exceptions), the receiving

Party may disclose the disclosing Party’s Confidential Information to

65

the extent (and only to the extent) such disclosure is reasonably necessary in the following instances:

12.3.1  in  order  to  comply  with Applicable  Law  (including  any  securities  law  or  regulation  or  the  rules  of  a

securities exchange) or with a legal or administrative proceeding;

12.3.2  in connection with prosecuting and defending litigation, seeking Regulatory Approvals for Products and
in  making  other  filings,  submissions,  and  communications  with  Regulatory Authorities  related  to  any  Products,  and,  solely
with  the  prior  written  consent  of  the  disclosing  Party  (not  to  be  unreasonably  withheld,  conditioned,  or  delayed)  filing,
prosecuting,  and  enforcing  Patent  Rights  solely  in  connection  with  exercising  the  receiving  Party’s  rights  and  fulfilling  the
receiving Party’s obligations pursuant to this Agreement; and

12.3.3  to actual or bona fide potential collaborators (including sublicensees), acquirers or assignees, investment

bankers, investors, lenders, and other advisors;

provided,  however, that (a) with respect to Sections 12.3.1 or 12.3.2 where reasonably possible, the receiving Party will notify
the disclosing Party of receiving Party’s intent to make any disclosure pursuant prior to making such disclosure so as to allow
disclosing Party to protect the confidentiality of the information to be disclosed (and the receiving Party shall reasonably assist
the disclosing Party upon request in taking such actions); and (b) with respect to Section 12.3.3, each of those named people
and entities are bound by restrictions on use and disclosure consistent with Article 12 (Confidentiality) (other than investment
bankers, investors, lenders, and other advisors, who must be bound prior to disclosure by commercially reasonable obligations
of confidentiality).

12.4     Terms of this Agreement; Publicity.  The Parties agree that the terms of this Agreement will be treated as

Except as required by Applicable Law or as permitted under Section 12.3 (Permitted Disclosure), each Party agrees not to issue
any  press  release  or  public  statement  disclosing  information  relating  to  this  Agreement  or  the  transactions  contemplated
hereby or the terms hereof without the prior written consent of the other Party, not to be unreasonably withheld, conditioned,
or delayed (provided that with respect to the content of a statement previously made in accordance with this Section 12.4, a
Party shall not require the consent of the other Party to disclose such content in a future statement or press release so long as
such information remains accurate and up-to-date). Notwithstanding the foregoing, a press release in the form attached hereto
as Schedule 12.4 shall be issued by the Parties on or as promptly as practicable after the Effective Date.

of their respective directors, officers, employees and agents (the “Universal Cells Indemnified Parties”), at Adaptimmune’s
cost  and  expense,  and  will  indemnify  and  hold  Universal  Cells  and  the  other  Universal  Cells  Indemnified  Parties  harmless
from  and  against  any  claims,  losses,  costs,  damages,  fees,  or  expenses  (including  reasonable  legal  fees  and  expenses)
(collectively,  “Losses”)  to  the  extent  resulting  from  any  claims,  actions,  suits,  or  proceedings  brought  by  a  Third  Party
(including product liability claims) (a “Third Party Claim”) arising out of (a) the gross negligence or willful misconduct of
Adaptimmune,  its Affiliates  or  their  respective  sublicensees  in  connection  with  the  performance  of  its  activities  under  this
Agreement;  (b)  [***];  or  (c)  the  Development,  Manufacture,  Commercialization,  or  other  exploitation  of  any  or  Unilateral
Adaptimmune Product by or on behalf of Adaptimmune, its Affiliates, or their respective sublicensees (including from product
liability and intellectual property infringement claims); except, in each case, to the extent such Losses result from clause (a),

16.3          Indemnification  Procedure.     The  foregoing  indemnity  obligations  shall  be  conditioned  upon  (a)  the
indemnified Party (“Indemnitee”) promptly notifying the indemnifying Party (“Indemnitor”)  in  writing  of  the  assertion  or
the commencement of the relevant Third Party Claim (provided,  however, that any failure or delay to notify shall not excuse
any  obligation  of  the  Indemnitor,  except  to  the  extent  the  Indemnitor  is  actually  prejudiced  thereby),  (b)  the  Indemnitee
granting the Indemnitor sole management and control, at the Indemnitor’s sole expense, of the defense of such Third Party
Claim and its settlement; provided,  however, that the Indemnitor shall not settle any such Third Party Claim without the prior
written consent of the Indemnitee if such settlement does not include a complete release from liability or if such settlement
would involve the Indemnitee undertaking an obligation (including the payment of money by the Indemnitee), would bind or
impair the Indemnitee, or includes any admission of wrongdoing by the Indemnitee or any admission that any Patent Right or
other intellectual property right of Indemnitee or this Agreement is invalid, narrowed in scope, or unenforceable, and (c) the
Indemnitee reasonably cooperating with the Indemnitor (at the Indemnitee’s expense). The Indemnitee shall have the right (at
its own expense) to be present in person or through counsel at all legal proceedings giving rise to the right of indemnification.

16.4     Insurance.  Each of the Parties will, at their own respective expense procure and maintain during the Term,
insurance policies adequate to cover their obligations hereunder and consistent with the normal business practices of prudent
biopharmaceutical companies of similar size and scope (or reasonable self-insurance sufficient to provide materially the same
level and type of protection). Such insurance will not create a limit to either Party’s liability hereunder.

INDIRECT,  SPECIAL, 

16.5     Limitation of Liability.   IN NO EVENT SHALL A PARTY BE LIABLE HEREUNDER TO THE OTHER
PARTY  FOR  ANY  PUNITIVE, 
INCIDENTAL,  OR  CONSEQUENTIAL  DAMAGES
(INCLUDING  LOST  REVENUE,  LOST  PROFITS,  OR  LOST  SAVINGS)  HOWEVER  CAUSED  AND  UNDER  ANY
THEORY, EVEN IF IT HAS NOTICE OF THE POSSIBILITY OF SUCH DAMAGES. THE LIMITATIONS SET FORTH
IN THIS SECTION 16.5 SHALL NOT APPLY WITH RESPECT TO ANY BREACH OF ARTICLE 10 (EXCLUSIVITY)
OR ARTICLE 12 (CONFIDENTIALITY). NOTHING IN THIS SECTION 16.5 IS INTENDED TO LIMIT OR RESTRICT
THE  INDEMNIFICATION  RIGHTS  OR  OBLIGATIONS  OF A  PARTY  UNDER  SECTION  16.1  (INDEMNIFICATION
BY ADAPTIMMUNE) OR SECTION 16.2 (INDEMNIFICATION BY UNIVERSAL CELLS) WITH RESPECT TO ANY
DAMAGES PAID TO A THIRD PARTY IN CONNECTION WITH A THIRD PARTY CLAIM.

exercise, and no delay in exercising, any right, power, remedy, or privilege under this Agreement, or provided by statute or at
law or in equity or otherwise, shall impair, prejudice or constitute a waiver of any such right, power, remedy, or privilege or be
construed as a waiver of any breach of this Agreement or as an acquiescence therein, nor shall any single or partial exercise of
any such right, power, remedy, or privilege preclude any other or further exercise thereof or the exercise of any other right,
power, remedy, or privilege.

17.12      Interpretation.    Except  where  the  context  otherwise  requires,  wherever  used,  the  singular  shall  include  the
plural, the plural shall include the singular, and the use of any gender shall be applicable to all genders. The term “including”
as used herein means including, without limiting the generality of any description preceding such term. The word “will” shall
be construed to have the same meaning and effect as the word “shall.” The word “or” will not be exclusive. References to a
particular  Person  include  such  Person’s  successors  and  assigns  to  the  extent  not  prohibited  by  this Agreement.  The  words
“herein,” “hereof,” and “hereunder” and words of similar import will be construed to refer to this Agreement in its entirety and
not to any particular provision hereof. All references to a “business day” or “business days” in this Agreement means any day
other than a day that is a Saturday, a Sunday or any day banks are authorized or required to be closed in the State of New
York.  The  word  “notice”  means  notice  in  writing  (whether  or  not  specifically  stated)  and  will  include  notices,  consents,
approvals  and  other  written  communications  contemplated  under  this Agreement.  Provisions  that  require  that  a  Party,  the
Parties or any committee hereunder “agree,” “consent,” or “approve” or the like will require that such agreement, consent, or
approval be specific and in writing, whether by written agreement, letter, approved minutes, or otherwise (including email, but
excluding  instant  messaging).  When  used  in  this Agreement  “knowledge”  will  not  require  any  freedom  to  operate  or  other
similar searching to be performed by the applicable Party. The language in all parts of this Agreement shall be deemed to be
the language mutually chosen by the Parties. The Parties and their counsel have cooperated in the drafting and preparation of
this Agreement,  and  this Agreement  therefore  shall  not  be  construed  against  any  Party  by  virtue  of  its  role  as  the  drafter
thereof.

17.13   Execution In Counterparts.  This Agreement may be executed in counterparts, each of which counterparts,
when  so  executed  and  delivered,  shall  be  deemed  to  be  an  original,  and  all  of  which  counterparts,  taken  together,  shall
constitute one and the same instrument.

17.14      No  Third  Party  Beneficiaries.    No  person  or  entity  other  than  Universal  Cells  and  Adaptimmune  and
permitted assignees hereunder shall be deemed an intended beneficiary hereunder or have any right to enforce any obligation
of this Agreement.

17.15      Subcontracting;  Performance  by  Affiliates.    Each  Party  may  engage  its  Affiliates  or  Third  Party
subcontractors (including contract research organizations and contract manufacturing organizations) to perform certain of its
obligations  under  this  Agreement  without  the  prior  written  consent  of  the  other  Party.  Any  Affiliate  or  Third  Party
subcontractor  to  be  engaged  by  a  Party  to  perform  such  Party’s  obligations  set  forth  in  this  Agreement  will  meet  the
qualifications  typically  required  by  such  Party  for  the  performance  of  work  similar  in  scope  and  complexity  to  the
subcontracted  activity.  The  activities  of  any  such  Third  Party  subcontractors  or Affiliates  performing  on  behalf  of  a  Party
under  this Agreement  will  be  considered  activities  of  such  subcontracting  Party  under  this Agreement.  The  subcontracting
Party will be responsible for

82

ensuring compliance by any such Third Party subcontractors or Affiliates with the terms of this Agreement, as if such Third
Party(ies) or Affiliate are such Party hereunder.  Notwithstanding the foregoing, the second, third, and fourth sentence of this
Section 17.15 does not apply to activities related primarily to Universal Cells Program Targets and Universal Cells Program
Products.

17.15.1            If [***] engages an Affiliate to perform activities pursuant to this Agreement, then [***] shall
enter  into  an  arrangement  with  such Affiliate  immediately  prior  to  the  commencement  of  such  activities  under  which  any
Patent Rights and Know-How arising in the course of such Affiliate’s performance of such activities shall be either assigned to
[***], or licensed to [***] as necessary to render such Patent Rights and Know-How to be Controlled by [***] for purposes of
this Agreement.    Furthermore,  [***]  agrees  not  to  undertake  any  transfer  of  Patent  Right  or  Know-How  that  is  licensed  to
[***]  pursuant  to  this Agreement  to  any Affiliate  after  the  Effective  Date  in  a  manner  that  would  render  any  such  Patent
Rights or Know-How to no longer be Controlled by [***] pursuant to this Agreement.

Press Release

Astellas and Adaptimmune Enter into Agreement to Co-Develop and Co-Commercialize 
Stem-Cell Derived Allogeneic CAR-T and TCR T-Cell Therapies

TOKYO and PHILADELPHIA, PA, OXFORDSHIRE, United Kingdom, January XX, 2020 (GLOBE NEWSWIRE) --
Astellas Pharma Inc. (TSE: 4503, President and CEO: Kenji Yasukawa, Ph.D., “Astellas”), through its wholly-owned
subsidiary Universal Cells, Inc, and Adaptimmune Therapeutics plc (Nasdaq:ADAP), a leader in cell therapy to treat cancer,
announced that they have entered into a co-development and co-commercialization agreement to bring new stem-cell derived
allogeneic T-cell therapies to people with cancer.

Astellas and Adaptimmune will agree on up to three targets and co-develop T-cell therapy candidates directed to those targets.
These targets will exclude target specific T-cell products in pre-clinical or clinical trials or those developed for other partners
at Adaptimmune. The collaboration will leverage Adaptimmune's target identification and validation capabilities for
generating target-specific T-cell Receptors (TCRs), chimeric antigen receptors (CARs), and HLA-independent TCRs that
recognize surface epitopes independently of the HLA profile of the tumor cell.  The collaboration will also utilize Astellas’
Universal Donor Cell and Gene Editing Platform it obtained through the acquisition of Seattle-based Universal Cells.

Adaptimmune has been collaborating with Universal Cells (now an Astellas Company) since 2015 on development of gene-
edited iPSC cell lines, for which Adaptimmune has rights to develop and commercialize resulting T-cell therapy products
using its proprietary process for generating T cells from stem cells without the use of feeder cell lines.

Astellas will fund research up until completion of a Phase 1 trial for each candidate. Upon completion of the Phase 1 trial for
each candidate, Astellas and Adaptimmune will elect whether to progress with co-development and co-commercialization of
the candidate, or to allow the other Party to pursue the candidate independently through a milestone and royalty bearing
licence, with the agreement allowing for either company to opt out. The companies will each have a co-exclusive licence
covering the co-development and co-commercialization of the product candidates within the field of T-cell therapy. If a
candidate is developed by one company only, the appropriate licences will become exclusive to the continuing party.

"Astellas positions immuno-oncology as one of its strategic areas of primary focus, and it is engaged in the development of
novel therapies for cancer patients using a new modality/technology," stated Naoki Okamura, Representative Director
Corporate Executive Vice President, Chief Strategy Officer and Chief Financial Officer, Astellas. "In addition to NK cells, T-
cells are an important component of cell therapy for immuno-oncology, and we look forward that this agreement with
Adaptimmune will enable us to create new stem-cell derived allogeneic T-cell therapies for a variety of cancers, including
solid tumors, in the future. We will continue to dedicate our efforts in delivering novel treatments for diseases with high unmet
medical needs, pursuing cutting-edge science and technological advances.”

 
 
 
 
 
 
 
 
“We are delighted to establish this significant co-development partnership with Astellas, which builds upon and substantially
extends an existing collaboration focused on gene editing of iPSC cells,” said Helen Tayton-Martin, Adaptimmune’s Chief
Business Officer and Co-Founder. “This new collaboration may encompass both CAR-T and TCR T-cell approaches,
including our novel HLA-independent TCR (“HiT”) platform. It brings together highly complementary skills and expertise
across the two organizations, and will enable the accelerated development of new, off-the-shelf T-cell therapy products for
people with cancer.”

Astellas will also have the right to select two targets and develop allogeneic cell therapy candidates independently. Astellas
will have sole rights to develop and commercialize these products, subject to necessary licenses and the payment of milestones
and royalties.

Under the terms of the agreement, Adaptimmune may receive up to $897.5 million in payments, including:

·     an upfront payment of $50 million.
·     development milestones totalling up to $73.75 million for each product if the collaboration product discovered in this

partnership is co-developed and commercialized by both companies

·     Up to $147.5 million in milestone payments per product and up to $110 million in sales milestones for products

developed unilaterally by Astellas.

4 . 2 .         Audits. To the extent required for Adaptimmune to satisfy its obligations under Applicable Law, Adaptimmune may audit Universal, no more
than  once  in  any  calendar  year,  for  compliance  with Applicable  laws. Adaptimmune  shall  provide  at  least  20  Business  Days’  notice  of  such
requirement  to  audit.  Universal  will  enable Adaptimmune  or  its  designated  Third  Party  inspector  to  carry  out  such  audit  including  making  all
Research  Documentation  and Additional  Documentation  (if  necessary)  available,  providing  access  to  facilities  used  in  the  performance  of  the
Research Program and providing access to relevant personnel in each case to the extent necessary for Adaptimmune to satisfy its obligations under
Applicable Law. Universal will procure similar rights of access and audit from any Third Party sub-contractors it uses in the performance of the
Research  Program.  To  the  extent Adaptimmune  requires  any  audit  after  termination  of  this Agreement  in  order  to  comply  with  its  obligations
under Applicable Law, such audit right shall continue to apply after termination of this Agreement. In other cases the right of audit shall cease on
termination of this Agreement.

4 . 3 .         Governmental Authority inspection. Universal will also permit any Governmental Authority to inspect its facilities and processes to the extent
such Governmental Authority requires such inspection in relation to the performance of the Research Program or later supply and manufacture of
Product  by Adaptimmune.  Universal  will  notify  Adaptimmune  if  it  receives  any  request  for  inspection  by  any  Governmental  Authority  and
provide Adaptimmune the opportunity to attend such inspection to the extent reasonable possible and in each case to the extent relevant to the
Research Program or facilities used in the performance of the Research Program by Universal.

4 . 4 .         Non-conformance.  Should  any  inspection  (whether  under  Section  4.2  or  4.3)  identify  any  non-conformance  with Applicable  Laws  or  other
requirement, Universal shall promptly correct such non-conformance and shall keep Adaptimmune informed of the progress of such correction.
Adaptimmune  may  carry  out  further  inspections  to  assess  the  progress  of  such  correction  and  to  verify  that  any  non-conformance  has  been
corrected.

5.           Grant of Rights

5 . 1 .   Licence  Grants  to Adaptimmune.    Universal  hereby  grants  to Adaptimmune  an  exclusive,  sub-licenseable,  worldwide  right  and  licence  in  the
Field, with the right to grant sublicences, under the Universal Patents (excluding the Sublicensed IP) and Universal Know-how to use, sell, supply,
manufacture  (including  to  have  manufactured),  import,  research,  develop  (including  to  have  developed)  and  distribute  (through  multiple
distribution  levels)  the  Products.  For  clarity,  (a)  the  foregoing  license  does  not  transfer  any  ownership  of  the  Universal  Patents,  Universal
Materials  and Universal Know-how to Adaptimmune and (b) the foregoing license under the Universal Patents and Universal Know-How does
not include, and Universal does not grant to Adaptimmune under this

18

Agreement, any sublicense under any patent or other Intellectual Property Rights Controlled by [***] or by [***].

5.2.         Diligence Obligations. Other than as provided under the Research Plan or explicitly otherwise provided in this Agreement, Adaptimmune shall be
solely responsible for the Exploitation of the Products in its sole discretion. Adaptimmune shall use Commercially Reasonable Efforts to further
develop and to seek Regulatory Approval and to commercialise at least one Product.  Save as explicitly provided in this Section 5.2, Universal
acknowledges and agrees that nothing in this Section 5.2 is intended, or shall be construed, to require Adaptimmune to Exploit a specific Product
providing  that  if Adaptimmune  decides  to  discontinue  the  development  of  one  Product  in  favour  of  another  Product  its  obligations  under  this
Section  5.2  shall  cease  with  respect  to  such  discontinued  Product  in  favour  of  such  other  Product.    Save  as  provided  in  this  Section  5.2,
Adaptimmune  shall  have  no  other  obligation,  express  or  implied,  to  Exploit  the  Products.    Notwithstanding  the  foregoing,  if Adaptimmune  (a)
makes  any  decision  to  cease  working  on  the  development  or  Exploitation  of  any  Product;  or  (b)  has  no  good  faith  intent  to  further  develop  or
Exploit any Product and ceases actively working on the development or Exploitation of any Product for a period of [***] consecutive [***], then
upon written notice Universal shall have the right to terminate this Agreement.

5 . 3 .         Limitation on Adaptimmune diligence obligations.  Universal acknowledges that Adaptimmune is in the business of developing, manufacturing
and selling pharmaceutical products and nothing in this Agreement shall be construed as restricting such business or imposing on Adaptimmune a
duty to market and/or sell and exploit the Products to the exclusion of, or in preference to, any other product or process, or in any way other than in
accordance with its normal commercial practices and those of its Affiliates.

5.4.         Sublicences. Adaptimmune and Universal agree to enter in to the Sublicenses, approved versions of which are attached in Schedules 2 and 3. Both

Parties shall execute such Sublicenses on the Effective Date.

5 . 5 .         Licence Grant to Universal. Adaptimmune grants to Universal a non-exclusive, non-transferable licence in the Field, without the right to grant
sublicenses, under its Intellectual Property Rights to the extent necessary for Universal to perform its obligations under the Research Program. The
licence granted under this Section 5.5 will terminate on completion of all Research Activities delegated to Universal under the Research Plan.

5 . 6 .         Licence Grant for [***]. Adaptimmune also grants to Universal a non-exclusive license under the [***] solely to the extent required under the
[***]. Such license is not intended to give Universal any additional rights or licenses over and above those provided in Section 5.5 above.

6.           Consideration

6.1.         Effective Date Payment.  In partial consideration of the licenses and other rights granted by Universal to Adaptimmune herein and subject to the

terms and conditions of this Agreement, Adaptimmune shall pay the sum of two and a half million US Dollars

19

(US$2,500,000) to Universal within ten (10) Business Days of the Effective Date subject to receipt of an invoice from Universal.

6 . 2 .         Development Milestones. On achievement of the milestones set out below (“Development Milestones”), Adaptimmune shall pay the following

payments to Universal, whether such milestones are first achieved by Universal or Adaptimmune:

(1) Approval of Phase 1 of the Research Plan by the JSC
and completion of first project committee meeting:

US$3,000,000

(2) [***]

(3) [***]

(4) [***]

(5) [***]

(6) [***]

(7) [***]

US$[***]

US$[***]

US$[***]

US$[***]

US$[***]

US$[***]

If any of the Development Milestones require a decision by the JSC or Adaptimmune, the JSC or Adaptimmune (as applicable) shall provide their
decision within either (a) where any delivery criteria agreed for any deliverable require characterisation of such deliverable by Adaptimmune or
performance of testing on any such deliverable, as soon as reasonably possible and in any event within ninety (90) days following applicable event
first coming up for consideration; or (b) where no characterisation or testing is required, thirty (30) days after the applicable event first comes up
for  consideration.    If  the  JSC  or Adaptimmune  (as  applicable)  does  not  decide  to  move  to  the  next  Phase  or  does  not  provide  its  approval  or
acceptance,  then  upon  Universal  providing  thirty  (30)  days  written  notice  and  unless  there  is  mutual  agreement  by  the  Parties  otherwise  this
Agreement  shall  terminate.    For  the  purposes  of  interpreting  the  Development  Milestones  above:  [***]  Cell  Bank  (“MCB”)  of  a  B2M-edited,
pluripotent Universal Donor Cell (“UDC”)  line  engineered  to  prevent  cell  surface  expression  of  polymorphic  HLA  class  I  molecules  and  with
mutations in the RFXANK gene to prevent HLA-class II expression and as further defined in the Research Plan; “TCA-UDC” shall mean a T-cell
adapted UDC line engineered to express a specific TCR or TCR variant with further mutations to prevent the expression of the endogenous TCR;
“WCB” shall mean a Working Cell Bank.

6 . 3 .         Modifications  to  Development  Milestones.  The  Parties  accept  that  the  above  milestones  are  based  on  the  Research  Program  as  outlined  in
Schedule    1  and  reflect  reimbursement  of  the  anticipated  development  expenses  undertaken  by  Universal.    Where  the  scope  of  such  Research
Program materially changes or requires Universal to take on a materially higher resource or financial burden, the Parties shall negotiate adjustment
to the above Development Milestones in good faith to reflect such increased scope, resource or financial burden.

6 . 4 .         Adjustments to Development Milestones. Where any Research Activities are specified to be performed by Universal in the Research Plan and
Universal is unable to perform such Research Activities or alternatively is delayed in the start of performance of such Research Activities and in
accordance  with  Section  2.3 Adaptimmune  takes  over  the  performance  of  such  Research Activities  or  appoints  a  Third  Party  to  carry  out  such
Research Activities, the Development Milestone will be reduced on a pro-rated basis to reflect the reduction in work activities being conducted by
Universal. Where a Third Party is used by Adaptimmune to perform such Research Activities the reduction shall additionally cover the costs of
such  Third  Party  performing  the  Research Activities  where  greater  than  the  pro-rated  reduction  in  level  of  Development  Milestone.    Where  no
activities  are  performed  by  Universal  under  a  Development  Milestone  as  a  result  of  an  inability  to  perform  by  Universal,  no  Development
Milestone shall become due and owing on achievement of such milestone by Adaptimmune.

6 . 5 .         Product Milestones.  Adaptimmune shall pay the following product milestone payments on the first Product to achieve each of the following

milestones (“Product Milestones”):

(1) [***]

(2) [***]

(3) [***]

US$[***]

US$[***]

US$[***]

In this Section 6.5: (a) a “Pre-Existing Adaptimmune Product” shall mean a Product which comprises a sequence for a TCR and in relation to
which Adaptimmune has previously received Regulatory Approval for a product comprising the same TCR sequence or a non-material variant of
such  TCR  sequence;  (b)  a  “New Adaptimmune  Product”  shall  mean  a  Product  comprising  a  sequence  for  a  TCR  and  in  relation  to  which
Adaptimmune has not previously received Regulatory Approval or filed an IND (or foreign equivalent) for a product comprising the same TCR
sequence or a non-material variant of such TCR sequence.

6 . 6 .         Notice.  Adaptimmune shall give Universal written notice within twenty (20) Business Days of the first achievement of each milestone event set
forth in Sections 6.2 (to the extent Universal is not already aware of achievement) and 6.5 above.  After receiving such written notice, Universal
shall  submit  an  invoice  to  Adaptimmune  for  the  amount  of  such  milestone  payment,  and Adaptimmune  will  pay  Universal  the  applicable
milestone payment within thirty (30) days after receipt of an invoice from Universal.

6 . 7 .         One-Time Payments.  Each individual milestone payment (whether a Development Milestone or Product Milestone) is payable one time only
regardless of the number of Products developed and/or commercialized and regardless of the number of times any of the applicable events occurs
with respect to any Product.  Where any milestone event is not achieved the relevant Product Milestone or Development Milestone shall not be due
and owing.

21

    
 
 
 
 
 
 
 
 
 
6.8.         No Additional Milestones.  In addition and for the avoidance of doubt, Adaptimmune will not be obligated to make any other payments in respect

of the above milestone events to Universal and/or Third Parties.

6 . 9 .         Profit Share.  Following expiry of the first [***] period after First Commercial Sale of the First Multi-Indication Product by Adaptimmune its
Affiliate  or  sublicensee, Adaptimmune  will  calculate  the  profit  share  due  to  Universal  in  relation  to  the  commercialisation  of  such  First  Multi-
Indication Product. The profit share for such [***] period, and each consecutive [***] period (each a “Profit Share [***]”) until expiration of the
last Valid Claim, shall be calculated as follows:

[***]

The New Mean Average Cost of Supply shall be the [***] over the [***] of sale for the [***] sold by Adaptimmune or its Affiliate or sublicensee,
the first month starting on date of First Commercial Sale of such Product.

The Old Mean Average Cost of Supply shall be the [***] for the product sold by Adaptimmune or its Affiliate or sublicensee [***] as used in the
[***] as calculated using the [***] immediately preceding date of First Commercial Sale of the First Multi-Indication Product. [***].

The Profit share due and payable shall be calculated in US dollars. Where any calculation of Mean Average Cost of Supply requires conversion
from a currency other than US dollars, Adaptimmune shall carry out such conversion using Adaptimmune’s customary and standard internal
exchange rates. Where the Old Mean Average Cost of Supply is lower than the New Mean Average Cost of Supply, no profit share shall be
payable.

If the Profit Share Amount is negative, then the First Multi-Indication Product shall be subject to the royalty under Section 6.12 and no further
Profit Share shall be payable or owing from Adaptimmune.

6.10.       Valid Patent limitation. The profit share payable in accordance with Section 6.9 above shall only be payable on Products which are Covered by a
Valid Claim. Once the last Valid Claim to Cover the First Multi-Indication Product expires, any obligation to pay the profit share in relation to
such Product shall cease.  Except as set forth in the last paragraph of Section 6.9, for clarity no royalty shall be payable on the sale of a First Multi-
Indication Product.

6.11.       Profit Share report.  Adaptimmune will deliver to Universal a report detailing the profit share due to Universal and calculated in accordance with
Section 6.9 within sixty (60) calendar days of the expiry of each Profit Share [***]. Adaptimmune will pay the relevant profit share to Universal
following receipt of invoice from Universal and within 30 days of receipt of such invoice.

6 .1 2 .       Royalties. In addition to the profit share payable under Section  6.9, on a country by country and Product by Product basis and for all Products

other than the First Multi-Indication Product (unless subject to a royalty pursuant to the last paragraph of Section

22

6.9), Adaptimmune shall pay to Universal a royalty of [***]% of Net Sales. Adaptimmune’s obligation to pay royalty with respect to any Product
shall commence upon the First Commercial Sale of a Product in a country and shall expire on the earlier of (i) the expiration of the last Valid
Claim to Cover such Product; and (ii) the date that is [***] years from the First Commercial Sale of such Product in a country (“Royalty Term”).
On expiration of the Royalty Term in relation to any Product, no further royalties shall be due or payable in relation to the sale of such Product.

6.13.       Currency Conversion for Net Sales. With respect to sales of Product in US dollars, the Net Sales shall be expressed in US dollars. With respect to
sales of Products in a currency other than US dollars, the Net Sales shall be reported in US dollars and converted using Adaptimmune’s customary
and standard internal exchange rates. The basis of any conversion shall be specified in the relevant Royalty Report.

6.14.       Royalty Reports. Following First Commercial Sale of a Product other than the First Multi-Indication Product, Adaptimmune shall provide a report
to Universal within [***] of each calendar quarter (“Royalty Report”), the first such report being due within [***] days after expiry of the calendar
quarter in which the First Commercial Sale of a Product (excluding the First Multi-Indication Product unless subject to a royalty pursuant to the
last paragraph of Section 6.9) is made. The Royalty Report shall include (a) the total Net Sales for each Product worldwide; and (b) calculation of
the royalty due to Universal under Section 6.12 above. On receipt of such Royalty Report, Universal will provide an invoice for the royalty and
Adaptimmune shall pay such royalty within 30 days of receipt of invoice.

6 . 1 5 .       Interest. Payments which are not made when due may bear interest as of the due date until the date the amount is effectively received on the
account  of Universal, at a rate of EURIBOR (12 months) plus [***]% calculated on a weekly basis for every week that the payment is due but
unpaid. Universal shall notify Adaptimmune prior to making any interest charge on any overdue payment, providing at least 5 Business Days prior
notice.

6 .1 6 .       Mode of Payment.  All payments set forth in this Section 6 shall be remitted by wire transfer to a bank account as Universal may designate in

writing.

6.17.       Currency.  All payments required under this Section 6 shall be made in U.S. Dollars.

6.18.       Taxes.

6.18.1          General. Universal alone shall be responsible for paying any and all taxes (other than withholding taxes required by Applicable Law to
be  paid  by  Adaptimmune)  levied  on  account  of,  or  measured  in  whole  or  in  part  by  reference  to,  any  Payments  it
receives.   Adaptimmune  shall  deduct  or  withhold  from  the  Payments  any  taxes  that  it  is  required  by Applicable  Law  to  deduct  or
withhold and shall reasonably assist Universal in obtaining any such deductions.

6 . 1 8 . 2          Indirect Taxes.   All  amounts  payable  by Adaptimmune  under  this Agreement  are  stated  exclusive  of  any  Indirect  Taxes,  which

Universal may be obliged to

23

charge.    If  any  Indirect  Taxes  are  chargeable  in  respect  of  any  Payments,  Adaptimmune  shall  pay  such  Indirect  Taxes  at  the
applicable rate in respect of such Payments following receipt, where applicable, of an Indirect Taxes invoice in the appropriate form
issued  by  Universal  in  respect  of  those  Payments.    The  Parties  shall  issue  invoices  for  all  amounts  payable  under  this Agreement
consistent  with  Indirect  Tax  requirements  and  irrespective  of  whether  the  sums  may  be  netted  for  settlement  purposes.    If  such
amounts of Indirect Taxes are refunded by the applicable Governmental Authority or other fiscal authority to Universal subsequent to
payment, the Party receiving such refund will transfer such amount to the paying Party within sixty (60) days of receipt. The Parties
agree to reasonably cooperate to provide any information required by the Party pursuing a refund of Indirect Taxes paid.

6 . 1 9 .       Operating Licences.  Each  Party  is  solely  responsible  for  payment  required  under  any  operating  licences  or  permits  including  any  required  to

perform its Research Activities in accordance with Applicable Laws.

6.20.       Records. Adaptimmune shall keep and maintain records of its sales of Products in sufficient detail to enable Universal to verify the accuracy of
Payments due from Adaptimmune and pursuant to an inspection under Section  6.21. Adaptimmune shall keep such records for a period of  five
(5) years from the end of the calendar year in which the relevant Product sales were made.

6 . 2 1 .       Inspections. Universal shall be entitled  to  appoint  an  independent  third  party  qualified  accountant  or  a  person  possessing  similar  professional
status and associated with an independent accounting firm acceptable to the Parties to verify the level of Net Sales accounted for by Adaptimmune
in accordance with Section 6.12 and the basis for the calculation of profit share in accordance with Section  6.9.  Adaptimmune shall make its
records  available  as  set  forth  in  this  Section  6.21.    The  accounting  firm  shall  enter  into  appropriate  obligations  with Adaptimmune  to  treat  all
information it receives during its inspection in confidence.  Such audit right shall apply no more than once in any calendar year and shall only
relate to the previous three (3) calendar year’s records (to the extent not previously audited by Universal). The independent third party shall only
be entitled to report to Universal as to whether or not the Net Sales of any Product or the calculation of Profit Share are materially accurate. Where
any  inspection  identifies  any  shortfall  in  the  Payments  required  to  Universal,  Adaptimmune  shall  make  up  such  shortfall  within  30  days  of
receiving notice of such shortfall. Where any inspection identifies an overpayment in the Payments required to Universal, Adaptimmune shall be
entitled to deduct the amount of such overpayment from the next Payment or Payments made to Universal. Universal shall pay the cost of any
inspection  unless  such  inspection  identifies  a  shortfall  in  payments  in  the  preceding  calendar  year  in  excess  of  five  (5)  percent  in  which  case
Adaptimmune shall pay the reasonable costs of the Third Party carrying out such inspection.

6 .2 2 .       Investment. In addition to the above Payments, Universal shall provide Adaptimmune with the right to participate in the next two (2) Qualified

Equity Investment Events that occur after the Effective Date, on the following terms:

24

6.22.1          If  Universal  proposes  to  conduct  a  Qualified  Equity  Investment  Event,  then  it  will  provide  Adaptimmune  with  as  much  notice  as
reasonably  possible  and  in  any  event  at  least  twenty  (20)  Business  Days  prior  written  notice  of  the  estimated  initial  closing  of  such
Qualified Equity Investment Event (a “Financing Notice”), which Financing Notice will also describe the principal terms of the Qualified
Equity Investment Event.

6.22.2       If Adaptimmune wishes to participate in such Qualified Equity Investment Event, it must notify Universal within ten Business Days after

delivery of the Financing Notice, in which case:

6.22.2.1. Universal will allow Adaptimmune to participate in the initial closing of the Qualified Equity Investment Event;

6.22.2.2. Universal will permit Adaptimmune to review the initial closing, such stock purchase agreement, investors’ rights agreement, co-
sale agreement, voting agreement and/or other agreements as are entered into by the investors in the Qualified Equity Investment
Event generally (“Investment Documents”) and both Universal and Adaptimmune will negotiate in good faith and on a timely
basis any changes required by Adaptimmune to such Investment Documents; and

6.22.2.3. Adaptimmune will execute and deliver to Universal at the initial closing, the agreed Investment Documents.

“Qualified  Equity  Investment  Events”  means  a  transaction  or  series  of  related  transactions,  conducted  primarily  for  the  purpose  of  raising
additional working capital, in which Universal sells shares of its preferred stock to new or existing investors, other than to a Universal licensee or
collaborator in connection with the grant of a license or entering into a collaboration.

Adaptimmune’s rights and Universal’s obligations under this Section 6.22 shall terminate on the earliest to occur of (a) the initial closing of the
second Qualified Equity Investment Event occurring after the date of this Agreement, (ii) a Change of Control of Universal, or (iii) an initial public
offering of Universal’s common stock pursuant to a registration statement under the Securities Act of 1933, as amended.

Adaptimmune’s agreement to participate in any such financing or investment shall be entirely at its discretion. The exact level of any contribution
or financing shall be agreed as part of any financing round.

8 . 2 .         Prosecution of Arising IP. Adaptimmune shall be entitled in its sole discretion to control and take decisions in relation to the filing, prosecution,
maintenance  and  obtaining,  (including  carrying  out  any  interferences,  reissue  proceedings  and  re-examinations),  throughout  the  world  of  any
patent application Covering any Arising IP solely or jointly owned by Adaptimmune and all Patents granted therefrom at its expense and save as
provided further below. Adaptimmune shall keep Universal reasonably informed through the JSC (to the extent still in existence or otherwise by
notice in writing) of any filings of patent applications Covering any such Arising IP and the progress of such patent applications. Universal shall
provide all necessary powers of attorney to Adaptimmune to allow Adaptimmune to carry out such prosecution and maintenance.  Universal shall

27

be entitled in its sole discretion to control and take decisions in relation to the filing, prosecution, maintenance and obtaining, (including carrying
out any interferences, reissue proceedings and re-examinations), throughout the world of any patent application Covering any Arising IP solely
owned by Universal and all Patents granted therefrom at its expense. In relation to any patent applications covering any jointly owned Arising IP
under  Section  7.2.5,  such  patent  applications  shall  be  drafted  jointly  by  the  Parties  and  advisers  for  each  Party  shall  work  closely  to  ensure
alignment  on  the  contents  of  such  patent  applications. Any  patent  application  filing  shall  require  the  approval  of  both  Parties  prior  to  filing.
Adaptimmune will file and prosecute any mutually approved patent application but shall keep Universal fully informed of the prosecution of such
patent applications and Patents granted therefrom. The parties shall cooperate to coordinate same-day Patent application filings for Arising IP, as
requested by the other party, for any provisional or nonprovisional patent applications (but for clarity not any continuations, continuations-in-part
or  divisionals)  as  for  Patent  application  filings  within  the  Universal  Cells  Background  IP  or Adaptimmune  Background  IP  that  are  directed  to
subject matter inventions that were used to identify, produce or develop a Product during the performance of activities under this Agreement to
avoid jeopardizing patentability of any such Patent.

8 . 3 .         Support.  Universal  shall  provide  reasonable  support  in  relation  to Adaptimmune's  prosecution  and  maintenance  of  any  patent  applications  or
Patents  Covering  the Arising  IP  solely  or  jointly  owned  by Adaptimmune,  subject  to  reimbursement  of  out  of  pocket  expenses  that  Universal
necessarily incurs in providing such support.  Adaptimmune shall provide Universal with updates (at the JSC or on the occurrence of any material
event in relation to any Patent) in relation to the progress of any patent application or Patent claiming any such Arising IP.

8 . 4 .         Election not to Prosecute.  If, Adaptimmune or Universal (each a “Prosecuting Party”) elects not to pursue or continue the filing, prosecution
(including  any  interferences,  reissue  proceedings  and  re-examinations)  or  maintenance  of  any  Patent  Covering  any Arising  IP  solely  or  jointly
owned by Adaptimmune or Universal respectively in any Major Territory, the relevant Prosecuting Party shall so notify the other Party promptly
in writing in sufficient time (usually 45 days but may be a shorter period depending on the notice given to Prosecuting Party by the relevant patent
office) in advance to enable other Party to meet any deadlines by which an action must be taken to establish or preserve any such rights in such
notified Patent.  Upon receipt of any such notice from Prosecuting Party and to the extent possible under any Third Party agreement existing as at
the  Effective  Date,  the  non-Prosecuting  Party  shall  have  the  right,  but  not  the  obligation,  to  pursue  the  filing  or  registration,  or  support  the
continued prosecution (but excluding any interferences, reissue proceedings and re-examinations) or maintenance, of such notified Patent, at its
expense in such country. The non-Prosecuting Party will keep the Prosecuting Party reasonably informed with regard to the current status of any
Patent  for  which  non-Prosecuting  Party  takes  over  responsibility  for  under  this  Section    8.4,  including  providing  copies  of  any  material
correspondence with relevant patent offices.

8.5.         CREATE Act.  Notwithstanding anything to the contrary in this Section 8 no Party shall have the right to make an election under the Cooperative

Research and  Technology

28

Enhancement Act  of  2004,  35  U.S.C.  103(c)(2)-(c)(3)  (the  “CREATE Act”)  when  exercising  its  rights  under  this  Section  8  without  the  prior
written consent of the other Party. With respect to any such permitted election, the Parties shall use reasonable efforts to cooperate and coordinate
their  activities  with  respect  to  any  submissions,  filings  or  other  activities  in  support  thereof.    The  Parties  acknowledge  and  agree  that  this
Agreement is a “joint research agreement” as defined in the CREATE Act.

9.           Enforcement of Patents

9 . 1 .         Rights and Procedures.  In  the  event  that  a  Party  is  notified  that  a  Third  Party  may  be  infringing  any  of  the Arising  IP,  Universal  Patents  or
Universal Know-How, such Party shall promptly notify the other Party in writing, identifying the alleged infringer (to the extent not in breach of
any Third Party obligation of confidence) and the alleged infringement complained of and furnishing the information of which it has been notified.

9.1.1            [***]

9.1.2            Save as provided in Section 9.1.1 and subject to Section 9.3 below, in relation to any other infringement or alleged infringement of a
Patent within the Universal IP, Universal may, in its sole discretion and in its own name, through counsel of its choosing, take any
measures  it  deems  appropriate  to  stop  such  infringing  activities  by  such  Third  Party  in  any  part  of  the  Territory  or  to  grant  to  the
infringing Third Party adequate rights and licenses necessary for continuing such activities. Any licences granted to any Third Party
shall not restrict or conflict with the licences and rights granted to Adaptimmune under this Agreement.

9.1.3                        Upon  reasonable  request  by  the  enforcing  Party  and  at  the  enforcing  Party’s  cost  and  expense,  the  other  Party  shall  provide  all
reasonable information and assistance, including allowing access to files and documents and to personnel who may have possession
of relevant information and, if necessary for prosecution of any legal action, joining in the legal action.

9.2.         Recovery. Any amounts recovered by an enforcing Party pursuant to Section 9.1.1 (expressly excluding Section 9.1.3), whether by settlement or
judgment, shall be shared as follows:  the enforcing Party shall first reimburse its costs and expenses for the infringement action and retain [***]
([***]%) of the remainder and provide the non-enforcing Party with the remaining [***]  ([***]%) of the remainder.

9.3.         Enforcement of Sublicensed IP. Any enforcement of any Sublicensed IP shall be subject to the terms of the Sublicenses.

10.         Potential Third Party Actions

10.1.       Third Party Licenses.  If, in the opinion of Adaptimmune, the Exploitation of the Products by Adaptimmune, its Affiliates or any of their licensees
infringes or misappropriates any Patent or any Intellectual Property Right of a Third Party in any country, then, Adaptimmune shall have the right,
but not the obligation to negotiate and obtain a license from such Third Party as necessary for Adaptimmune and its Affiliates and licensees to

29

Exploit the Products in such country.  Adaptimmune will be responsible for the performance of any license agreement it executes with such Third
Party. Adaptimmune  understands  and  accepts  that  it  shall  be  responsible  for  negotiation  of  any  agreements  with  Third  Parties  required  for  the
commercial  use  of  any  Third  Party  cell  lines  or  cell  banks  required  for  commercial  manufacture  and  sale  of  Product  (excluding  any  use  for
research and development or clinical trials).

10.2.       Invalidity or Unenforceability Defences or Actions.

10.2.1                    In  the  event  that  a  Third  Party  asserts,  as  a  defence  or  as  a  counterclaim  in  any  infringement  action,  that  any  Universal  Patent
(excluding any Arising IP) or any Arising IP solely owned by Universal is invalid or unenforceable, then Universal shall have the
right,  but  not  the  obligation,  through  counsel  of  its  choosing  to  respond  to  such  defence  or  defend  against  such  counterclaim  (as
applicable), including the right to settle or otherwise compromise such claim.

10.2.2          Similarly, if a Third Party asserts, in a declaratory judgment action or similar action or claim filed by such Third Party, that any Patent
within the Arising  IP solely or jointly owned by Adaptimmune is invalid or unenforceable, then Adaptimmune shall have the right,
but not the obligation, through counsel of its choosing to defend against such action or claim.

10.3.       Third Party Litigation.  In the event of any actual or threatened suit against Adaptimmune or Universal alleging that the Exploitation of Products
by  or  on  behalf  of Adaptimmune  under  this Agreement  infringes  the  Patent  or  Intellectual  Property  Rights  of  any  Person  (an  “Infringement
Suit”), the Party first becoming aware of such Infringement Suit shall promptly give written notice to the other Party.  In relation to any Products,
Adaptimmune shall have the right, but not the obligation, through counsel of its choosing, to assume direction and control of the defence of claims
arising therefrom (including the right to settle such claims in its sole discretion).

10.4.       Cooperation.  Each Party will provide to the other Party all reasonable assistance requested by such Party in connection with any action, claim or
suit under Section 10.2 or 10.3, including allowing such Party access to the other Party 's files and documents and to the other Party 's personnel
who may have possession of relevant information. The requesting Party shall pay the other Party’s reasonable out of pocket expenses in relation
thereto.  In  particular  the  other  Party  will  promptly  make  available  to  the  requesting  Party,  all  information  in  its  possession  or  control  that  it  is
aware will assist such Party in responding to any such action, claim or suit under Section 10.2 or 10.3.

11.         Confidentiality and Non-Disclosure

11.1.       Confidentiality.  At all times during the term of this Agreement and for a period of [***] years following termination or expiration hereof, each
Party (the “Receiving Party”) shall, and shall cause its officers, directors, employees, agents, Affiliates and sub-licensees to, keep confidential and
not  publish  or  otherwise  disclose  and  not  use,  directly  or  indirectly,  for  any  purpose,  any  Confidential  Information  of  the  other  Party  (the
“Disclosing Party”), except to the extent such disclosure or use is otherwise expressly permitted or licensed by the terms of this Agreement.

30

11.2.       Permitted Disclosures.  Each Party may disclose Confidential Information  to the extent that such disclosure is:

11.2.1                    made  in  response  to  a  valid  order  of  a  court  of  competent  jurisdiction  or  other  competent  authority;  provided,  however,  that  the
Receiving Party shall first have given notice to the Disclosing Party and given the Disclosing Party a reasonable opportunity to quash
any  such  order  or  obtain  a  protective  order  requiring  that  the  Confidential  Information  and  documents  that  are  the  subject  of  such
order be held in confidence by such court or authority or, if disclosed, be used only for the purpose for which the order was issued; and
provided  further  that  if  such  order  is  not  quashed  or  a  protective  order  is  not  obtained,  the  Confidential  Information  disclosed  in
response to such court or governmental order shall be limited to that information that is legally required to be disclosed in response to
such court or governmental order;

11.2.2          made by Adaptimmune or its Affiliates or its licensees to a Governmental Authority as may be necessary or useful in connection with
any  filing,  application  or  request  for  a  Regulatory  Approval  and  or  pricing  or  reimbursement  approval,  pre-  and  post-approval
marketing authorisations (including any prerequisite manufacturing approval or authorisation related thereto), labelling approval and
technical, medical and scientific licenses; provided, however, that reasonable measures shall be taken to assure confidential treatment
of such information, to the extent such protection is available;

11.2.3          made by a Party to a patent authority as may be necessary or useful for purposes of obtaining or enforcing a Patent (consistent with the
terms and conditions of Sections 8 and 9); provided, however, that reasonable measures shall be taken to assure confidential treatment
of such information, to the extent such protection is available;

11.2.4          otherwise required by Applicable Law or by stock exchange or other financial authority requirement;

11.2.5                    made  by Adaptimmune  or  its Affiliates  or  its  licensees  to  Third  Parties  as  may  be  necessary  or  useful  in  connection  with  the
Exploitation  of  Products,  including  subcontracting  or  sublicensing  transactions  in  connection  therewith  and  in  each  case  subject  to
such  Third  Parties,  where  reasonably  possible,  agreeing  confidentiality  obligations  substantially  equivalent  to  those  set  out  in  this
Agreement ; or

11.2.6          made by Universal or its Affiliates to actual or prospective investors or acquirers to the extent necessary for the purposes of such
investment or acquisition and provided that in each such case investors or acquirers are subject to written obligations of confidentiality
substantially equivalent to those set out in this Agreement.

31

Notwithstanding  the  foregoing,  in  the  event  that Adaptimmune  or  any  of  its Affiliates  is  required  by Applicable  Law  or  the  requirements  of  a
national securities exchange or another similar regulatory body to disclose this Agreement, in whole or in part, the Parties shall reasonably agree
on a redacted version of this Agreement as necessary to protect the Confidential Information of Universal prior to making such disclosure.

11.3.       Exclusions.  Notwithstanding the foregoing, Confidential Information shall not include any information that:

11.3.1          is or hereafter becomes part of the public domain by public use, publication, general knowledge or the like through no wrongful act,

fault or negligence on the part of the Receiving Party;

11.3.2          can be demonstrated by documentation or other competent proof to have been in the Receiving Party’s or its Affiliates’ possession

prior to disclosure by the Disclosing Party;

11.3.3                    is  subsequently  received  by  the  Receiving  Party  or  its Affiliates  from  a  Third  Party  who  is  not  bound  by  any  obligation  of

confidentiality with respect to said information;

11.3.4          is generally made available to Third Parties by the Disclosing Party without restriction on disclosure; or

11.3.5          is independently developed by or for the Receiving Party or its Affiliates without reference to the Disclosing Party’s Confidential

Information.

Specific aspects or details of Confidential Information shall not be deemed to be within the public domain or in the possession of the Receiving
Party  merely  because  the  Confidential  Information  is  embraced  by  more  general  information  in  the  public  domain  or  in  the  possession  of  the
Receiving Party.  Further, any combination of Confidential Information shall not be considered in the public domain or in the possession of the
Receiving  Party  merely  because  individual  elements  of  such  Confidential  Information  are  in  the  public  domain  or  in  the  possession  of  the
Receiving Party unless the combination and its principles are in the public domain or in the possession of the Receiving Party.

11.4.       Results. Universal and Adaptimmune shall each keep the Results confidential as if such Results were Confidential Information of the other Party,

save:

11.4.1          To the extent such disclosure is permitted for Confidential Information under Section 11.2 above;

11.4.2          to the extent such Results need to be disclosed to Third Parties (i) in the case of Universal for the further development of the Universal
Technology outside of the Field provided that if the Results to be disclosed would include information regarding the Field, then where
reasonably possible subject to such Third Party agreeing to obligations of confidentiality substantially equivalent to those set out in
this Agreement; and (ii) in the case of Adaptimmune for the further development and Exploitation of Products within the Field and
where

32

reasonably possible subject to such Third Party agreeing to obligations of confidentiality substantially equivalent to those set out in
this Agreement;

11.4.3          to the extent such Results are published under Section 11.5;

11.4.4          to the extent the Results satisfy any of the exclusions under Section 11.3.

1 1 . 5 .       Publications and Presentations.    The  Parties  acknowledge  that  scientific  publications  must  be  strictly  monitored  to  prevent  any  adverse  effect
from premature publication of results of the research and development activities hereunder.  Accordingly Universal shall not publish, present or
otherwise  disclose  Confidential  Information  of Adaptimmune  without  the  prior  written  consent  of Adaptimmune  which  can  be  withheld  in  its
absolute  discretion.    Where  either  Party  wishes  to  publish  any  Results  (“Publishing  Party”),  it  shall  provide  the  other  Party  with  prior  written
notice of such, where reasonably possible such notice being provided at least 30 days prior to any deadline for submission of such publication. The
non-Publishing Party shall be entitled to review and comment on the publication and to request removal of any Results which it considers would
(a) place it in breach or non-conformance with any Applicable Law or any requirement of any stock exchange rules or requirements; (b) would
invalidate or prevent the filing of any patent application or the prosecution of any existing patent application; or (c) would materially affect its
commercial  interests,  ongoing  development  programs  or  development  of  its  products  or  programs.    The  Publishing  Party  shall  incorporate  any
reasonable comments made by the non-Publishing Party and shall remove any Results which non-Publishing Party requests removed pursuant to
this Section 11.5. In relation to any Results which are specific to the Field or which relate to any clinical trial which Adaptimmune is controlling or
sponsoring, Adaptimmune shall be entitled to decline the publication of any such Results in its sole discretion. In relation to any Results which do
not relate to the Field, Universal shall be entitled to decline the publication of any Results in its sole discretion.

11.6.       Use of Name.  Neither Party, nor its Affiliates shall mention or otherwise use the name, insignia, symbol, trademark, trade name or logotype of
another Party or its Affiliates in any publication, press release, promotional material or other form of publicity without the prior written consent of
such other Party.  The restrictions imposed by this Section 11.6 shall not prohibit a Party from making any disclosure identifying another Party
that is required by Applicable Law or the requirements of a national securities exchange or another similar regulatory body, provided that any such
disclosure shall be governed by this Section 11.  Further, the restrictions imposed on each Party under this Section 11.6 are not intended, and shall
not  be  construed,  to  prohibit  a  Party  from  identifying  the  other  Party  in  its  internal  business  communications,  provided  that  any  Confidential
Information in such communications remains subject to this Section 11.

11.7.       Public Announcements. No public announcement concerning this Agreement, its subject matter or the transactions described herein shall be made,
either directly or indirectly, by Adaptimmune or Universal or their respective Affiliates, except as may be legally required by Applicable Laws,
regulations,  judicial  order,  or  required  by  stock  exchange  or  quotation  system  rule  without  first  obtaining  the  approval  of  the  other  Party  and
agreement  upon  the  nature,  text  and  timing  of  such  announcement,  which  approval  and  agreement  shall  not  be  unreasonably  withheld  or
delayed.  The Party desiring to make any such voluntary public announcement shall provide the other Party with a written copy

33

of the proposed announcement in reasonably sufficient time prior to public release to allow such other Party to comment upon such announcement,
prior to public release.  In the case of press releases or other public communications legally required, or required by stock exchange or quotation
system rule, to be made, the Party making such press release or public announcement shall provide to the other Party a copy of the proposed press
release or public announcement in written or electronic form upon such advance notice as is practicable under the circumstances for the purpose of
allowing  the  notified  Party  to  review  and  comment  upon  such  press  release  or  public  announcement.    Under  such  circumstances,  the  releasing
Party shall not be obligated to delay making any such press release or public communication beyond the time when the same is required to be
made in order to facilitate review and comment by the receiving Party.

12.         Trademarks

12.1.       Adaptimmune shall have the sole right to select the Trademarks for the marketing and sale of the Products; provided the Trademark is not a trade
mark registered by Universal. Adaptimmune shall own such Trademarks and all Intellectual Property Rights and other rights and goodwill with
respect  thereto.    Universal  shall  not,  and  shall  not  permit  its  Affiliates  to,  use  any  trademark  that  is  the  same  as  or  confusingly  similar  to,
misleading or deceptive with respect to or that dilutes any registered Trademark.

13.1.6          The conception, development and reduction to practice of the Universal  Know-How and Universal Patents has not, to Universal’s

knowledge, constituted or involved the misappropriation of trade secrets or other rights or property of any Person.

13.1.7          No claim or litigation has been brought or threatened as of the Effective Date by any Person alleging, and Universal is not aware of
any possible claim, whether or not asserted, that Adaptimmune’s use the Universal Patents and Universal Know-How would violate,
infringe or otherwise conflict or interfere with any intellectual property or proprietary right of any Person.

13.1.8          Universal has not previously entered into any agreement, whether written or oral, with respect to, or otherwise assigned, transferred,
licensed, conveyed or otherwise encumbered its right, title or interest in or to the Universal Patents or Universal Know-How in the

and not attributable to the loci and promoter,

37

the sequences thereof and any other sequences provided by Adaptimmune or the use of the Gene Editing Technology to deliver those sequences to
cells);  (c)  arise  as  a  result  of  any  use  by Adaptimmune  of  the  Universal  Technology  outside  of  the  scope  of  any  licence  agreement  negotiated
between Adaptimmune and the relevant Third Party or between Universal and the relevant Third Party (provided in the latter case Adaptimmune
has reviewed and approved the terms of such Third Party license and excluding [***] which are subject to Section 14.5(d) below); (c) relates to
any  part  of  the  Product  or  part  of  the  manufacturing  process  other  than  the  Universal  Technology;  or  (d)  arise  as  a  result  of  any  breach  by
Adaptimmune of Section 2.13.

1 4 . 6 .       Insurance.  Each Party shall have and maintain such type and amounts of liability insurance covering its liabilities under this Agreement as is
normal and customary in the industry generally. The requirement to maintain insurance under this Section 14.6 shall not limit the liability of a
Party under this Agreement.

15.         Term and Termination of Agreement

1 5 . 1 .       Term.  The term of this Agreement shall become effective as of the Effective Date and unless terminated earlier as provided herein (including

(the “Term”).

15.2.       Termination by Adaptimmune.  Adaptimmune shall have the right, in its sole discretion, to terminate this Agreement by giving thirty (30) days'
prior written notice to Universal (a) for safety or scientific reasons; (b) if a Third Party Patent is identified which would Cover any Product and a
licence  or  alternative  development  route  is  not  commercially  feasible  in Adaptimmune’s  sole  discretion;  or  (c)  in  the  event  it  does  not  wish  to
proceed with the next Phase of the Research Plan, based on the outcome of any previous Phase.

15.3.       Termination for Material Breach.  If either Party is in material breach of the Agreement (a “Breaching Party”), in addition to any other right and
remedy the other Party (the “Complaining Party”) may have, the Complaining Party may terminate this Agreement in its entirety by ninety (90)
days prior written notice (the “Notice Period”) to the Breaching Party, specifying the breach and its claim of right to terminate, provided always
that the termination shall not become effective at the end of the Notice Period if the Breaching Party cures the breach complained about during the
Notice  Period  (or,  if  such  default  cannot  be  cured  within  such  ninety  (90)  day  period,  if  the  Breaching  Party  commences  actions  to  cure  such
default within the Notice Period and thereafter diligently continues such actions).

15.4.       Termination for Insolvency. Either Party may (without limiting any other remedy it may have), terminate this Agreement with immediate effect if
the other Party becomes insolvent, is unable to pay its debts, or if an order is made or a resolution is passed for its winding up (except voluntarily
for the purpose of a solvent amalgamation or reconstruction), or if an administrator, administrative receiver or receiver is appointed over the whole
or any part of the other Party’s assets, or if the other Party makes any arrangement with its creditors or ceases to carry on business or does or
suffers any similar or analogous act existing under the laws of any country.

38

15.5.       Consequences of Termination

15.5.1          Termination of Rights. In the event of termination or expiry of this Agreement and save as otherwise explicitly provided all rights and
licences granted to Universal and to Adaptimmune under this Agreement shall terminate and each Party shall return all data, files,
records and other materials in its possession or control containing or comprising the other Party’s Information or other Confidential
Information to which such first Party does not retain rights hereunder (except one copy of which may be retained by the returning
Party's General Counsel or external law firm solely for archival purposes).

1 5 . 5 . 2          Licence  of Adaptimmune  Know  How.  On  expiry  of  the  Term  but  not  termination,  Universal  shall  grant Adaptimmune  a  non-
exclusive,  royalty  free,  fully  paid  up,  perpetual,  irrevocable,  worldwide,  assignable  right  and  licence  in  the  Field,  with  the  right  to
grant sublicences through multiple tiers, under the Universal Know How to Exploit and further develop the Products.

1 5 . 5 . 3          Return of Materials.  On termination but not expiry (a) each Party will return any Materials of the other Party to that other Party
promptly on termination, and (b) Adaptimmune and its Affiliates and sublicensees shall cease all use of the Deliverables (to the extent
such Deliverables cannot be used without a licence under any of Universal’s Intellectual Property Rights).

15.5.4          Remedies.  Early termination of this Agreement by a Party shall in no way affect or limit such Party’s right to claim against any of

Universal, or Adaptimmune for any damages arising out of the breach of this Agreement.

1 5 . 6 .       Change of Control. Universal shall notify Adaptimmune of any Change in Control of Universal in advance of such Change in Control where
possible or in any event within five (5) Business Days following such Change in Control.  If the Change in Control occurs prior to completion of
the  Research  Program,  then  when Adaptimmune  receives  notice  of  such  Change  in  Control,  if  the  surviving  entity  (excluding  any  Competitor)
does not also provide a written notice within five (5) Business Days of such Change of Control that the surviving entity will assume the obligations
of Universal and complete the Research Program, then: (a) Adaptimmune will have the option to terminate this Agreement immediately on written
notice and the provisions of Section 15.5 above shall apply to such termination; or (b) Adaptimmune may elect by provision of notice in writing to
Universal,  in  its  sole  discretion  to  perform  additional  parts  of  the  Research  Plan  previously  reserved  to  Universal.    Where  any  Development
Milestone was attributed to completion of such additional parts, such Development Milestone shall cease to be payable where Adaptimmune takes
over performance of the relevant Research Activities. Where any part of the Research  Plan  or  Phase  of  the  Research  Plan  was  part  performed,
following Adaptimmune taking over performance of such part or Phase of the Research Plan the Development Milestone for such part or Phase
will  be  pro-rated  accordingly  based  on  the  Research  Activities  performed  prior  to  receipt  by  Universal  of  notification  from  Adaptimmune.
Universal  will  cooperate  with Adaptimmune  to  ensure  that  any  handover  of  Materials  and  Information  required  for Adaptimmune  to  take  over
performance of Research Activities occurs promptly and Universal will make relevant

39

personnel available to ensure a smooth transition in such Research Activities. In the event of a Change in Control and Adaptimmune electing to
take over the Research Plan in accordance with Section 15.6(b) or in the event of a Change in Control in favour of a Competitor the following shall
apply:

15.6.1          The licences and rights granted by Adaptimmune to Universal shall immediately terminate save to the extent required to ensure a

smooth transition of the Research Activities to Adaptimmune;

15.6.2          Any reporting obligations from Adaptimmune to Universal shall cease and save as necessary under Section 6 for the purposes of
payment  of  the  Development  Milestones  and  Product  Milestones,  for  the  reporting  and  payment  of  Profit  Share  and  Royalty.
Adaptimmune  shall  be  under  no  further  obligation  to  continue  to  report  on  the  progress  of  the  Research  Program  or  to  share  any
results or development of any Deliverable or Product with Universal.

15.6.3          Universal shall immediately (a) provide to Adaptimmune all Results generated to date including any Deliverables (even if not in final
form)  or  otherwise  provide  access  to  such  Results  and  Deliverables  (in  the  case  of  cell  lines,  cell  banks  or  other  cell  based
deliverables or materials); and (b) to the extent any Research Activities are provided by a Third Party, provide access to such Third
Party  and  facilitate  an  ongoing  relationship  between  such  Third  Party  and Adaptimmune  to  enable Adaptimmune  to  complete  the
Research Program in its sole discretion.

15.6.4          The licence rights and access reports granted to Adaptimmune shall continue in full force and effect for the Term. The diligence
obligations under Section 5.2 shall continue to apply but for clarity, Adaptimmune shall be under no obligation to provide any reports
on  progress  or  any  detailed  reports  on  Product  sales,  nature  of  Product,  manufacturing  process  for  Product  or  timelines  for
Exploitation of any Product.

15.6.5          The JSC shall immediately cease as shall any project or other sub-committees save where such committees are required to facilitate

transition of the Research Activities to Adaptimmune.

15.6.6          Other terms of the Agreement shall remain in full force and effect.

Pending  notice  of  Change  in  Control  under  this  Section  15.6  with  a  Competitor  and  termination  or  transfer  of  Research  Program  to Adaptimmune  in
accordance with this Section 15.6, Universal will not permit the Third Party Competitor (or any of its employees) in respect of which the relevant Change in
Control  has  occurred  to  have  access  to  any  Confidential  Information  of Adaptimmune  (other  than  Confidential  Information  permitted  to  be  provided  in
accordance with Section 11 above).

15.7.       Application of US Bankruptcy Code. The Parties agree that the license rights granted under this Agreement are, and shall otherwise be deemed

to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code and similar laws and regulations outside of the

40

United States, licenses of rights to “intellectual property” as defined under Section 101 of the Bankruptcy Code or such other laws and regulations.
The Parties shall retain and may fully exercise all of their respective rights and elections under Section 365(n) of the Bankruptcy Code or similar
laws and regulations outside of the United States. During the duration of the Research Program, Universal agrees to provide to Adaptimmune a
copy of its audited accounts (or if not audited, its annual accounts or financial statements) within 30 days of finalisation, or alternatively the CEO
of  Universal  will  telephone  the  CEO  of Adaptimmune  within  30  days  of  annual  accounts  being  finalised  to  discuss  the  contents  of  the  annual
accounts and in particular financial status of Universal.

15.8.       Accrued Rights; Surviving Obligations.

1 5 . 8 . 1          Survival.  The termination of this Agreement shall not relieve any of Universal or Adaptimmune from performing any obligations
accrued prior to the date this Agreement terminates.  Subject to the foregoing, each of Universal or Adaptimmune obligations under
Section 1 (to the extent necessary for interpretation of other surviving Sections), Sections 2.6, 2.7, 4.1, 4.2, 7, 8, 11, 12, 13, 14, 15.
17, 18, 19, 20, 21 - 29 shall survive the termination or expiration of this Agreement.

16.            Anti-Corruption Laws

16.1.              Both  Parties  shall  ensure  that  in  connection  with  its  obligations  under  this Agreement,  they  shall  conduct  their  activities  in  a  manner  that  is
consistent with the Anti-Corruption Laws.  Each Party further undertakes that none of its or its Affiliates' employees, directors or officers shall,
directly or indirectly, engage in any activities that violate any Anti-Corruption Law (a) in order to influence official action of any Government
Official, or (b) with the intention of or as a condition to inducing any person to carry out a duty or function improperly or to reach a favourable
decision on an improper basis, in each case in connection with the activities contemplated under this Agreement.

16.2.       Universal shall promptly provide Adaptimmune with written notice of (a) becoming aware of a Material Anti-Corruption Law Violation by it or
any of its employees, directors or officers with respect to the subject matter of this Agreement, or (b) upon receiving a formal notification that it or
any of its employees, directors or officers is the target of a formal investigation by any Governmental Authority for a Material Anti-Corruption
Law Violation.

16.3.              Universal  acknowledges  that  its  undertakings  given  in  this  Section  16  are  material  to  Adaptimmune  in  entering  into  this
Agreement.  Notwithstanding any other provision of this Agreement, if Adaptimmune becomes aware of what it determines, acting reasonably, to
be a breach of these undertakings, then Adaptimmune shall be entitled to terminate this Agreement in its entirety, and any other agreement among
the  Parties,  on  notice  with  immediate  effect.    Subject  to  the  accrued  rights  of  the  Parties  pursuant  to  termination, Adaptimmune  shall  have  no
liability to Universal for any fees, reimbursements or other compensation or for any loss, cost, claim or damage resulting, directly or indirectly,
from such termination.  At the sole discretion of Adaptimmune, any breach of a Universal obligation with respect to its obligation in this Section
16 may be cured (if capable of

41

being cured) within a reasonable period of time after learning of such material breach or Material Anti-Corruption Law Violation.

17.         Assignment

17.1.       Neither Party may assign its rights or except as otherwise explicitly provided, delegate its obligations under this Agreement, whether by operation
of law or otherwise, in whole or in part without the prior written consent of the other Party, which consent shall not be unreasonably withheld,
except that a Party shall always have the right, without such consent: (a) to perform any or all of its obligations and exercise any or all of its rights
under  this Agreement  through  any  of  its Affiliates  or  licensees;  and  (b)  assign  any  or  all  of  its  rights  and  delegate  any  or  all  of  its  obligations
hereunder to any of its Affiliates or, subject to the terms of Section 15.6 to any successor in interest (whether by merger, acquisition, asset purchase
or otherwise) to all or substantially all of the business to which this Agreement relates, provided that such Party shall provide written notice to the
other Party within ninety (90) days after such assignment or delegation.  All validly assigned rights of any of Universal or Adaptimmune shall
inure to the benefit of and be enforceable by, and all validly delegated obligations of such party shall be binding on and be enforceable against, the
permitted successors and assigns of such party. Any attempted assignment or delegation in violation of this Section 17 shall be void.

18.         Severability

To the fullest extent permitted by Applicable Law, the Parties waive any provision of law that would render any provision in this Agreement invalid,
illegal or unenforceable in any respect.  If any provision of this Agreement is held to be invalid, illegal or unenforceable, in any respect, then such
provision will be given no effect by any of the Parties and shall not form part of this Agreement.  To the fullest extent permitted by Applicable Law
and if the rights or obligations of any Party will not be materially and adversely affected, all other provisions of this Agreement shall remain in full
force  and  effect,  and  each  Party  shall  use  their  best  efforts  to  negotiate  a  provision  in  replacement  of  the  provision  held  invalid,  illegal  or
unenforceable that is consistent with Applicable Law and achieves, as nearly as possible, the original intention of each of the Parties.

19.         Governing Law, Jurisdiction, Venue

19.1.       Governing Law.  This Agreement and any dispute or claim arising out of or in connection with it (whether contractual or non-contractual in nature
such  as  claims  in  tort,  from  breach  of  statute  or  regulation  or  otherwise)  shall  be  governed  by  and  construed  in  accordance  with  the  laws  of
England excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the
substantive  law  of  another  jurisdiction.    The  Parties  agree  to  exclude  the  application  to  this Agreement  of  the  United  Nations  Convention  on
Contracts for the International Sale of Goods.

42

arbitration procedures shall be English.  The arbitration proceedings including any outcome shall be confidential.  Nothing in this Section 19.2 will
preclude  any  of  the  Parties  from  seeking  equitable  interim  or  provisional  relief  from  a  court  of  competent  jurisdiction  including  a  temporary
restraining order, preliminary injunction or other interim equitable relief, concerning a dispute either prior to or during any arbitration if necessary
to protect the interests of such party or to preserve the status quo pending the arbitration proceeding.

application  of  this Agreement,  the  Parties  shall  use  the  following  non-binding  procedure  in  good  faith  prior  to  any  Party  pursuing  judicial
remedies provided that this shall not prevent any Party pursuing interim remedies to protect their rights.

20.2.      Each Party shall notify the other Party of the dispute in accordance with this Section 20.  The Parties shall use good faith efforts to resolve such
dispute  within  thirty  (30)  days  after  delivery  of  such  notice,  which  good  faith  efforts  shall  include  at  least  one  in-person  meeting  between

3.4.2. If Universal receives notice under the AAV/HLA-engineering licence that the University has been solicited by a Third Party who wishes to
license Licensed Patents for any field within the Field of Use that Adaptimmune or Universal is not diligently pursuing (hereinafter “Third Party Field”),
Universal shall so notify Adaptimmune, and Adaptimmune shall be entitled to be actively involved in any notifications made to University in relation to
such Third Party Field notification from University. Universal and Adaptimmune shall discuss which of the following options should be exercised in
response to such University’s notification:

 
3.4.2.1. Development Plan. Provide University with a reasonable rationale as to why offering a sublicense in Third Party Field would be
competitive with market opportunity Adaptimmune or Universal is either actively pursuing, or planning on pursuing; or

3.4.2.2. Direct Grant. Universal to grant a sublicense to the said soliciting Third Party in the Third Party Field on commercially reasonable
licence terms, such terms being subject to review and approval by Adaptimmune. Adaptimmune will not unreasonably withhold or delay its

5.1. Covenants Regarding the Manufacture of Licensed Products. Adaptimmune hereby covenants and agrees that the manufacture, use, sale, or
transfer of Licensed Products will comply with all applicable federal and state laws, including all federal export laws and regulations. Adaptimmune
understands that there is a requirement under the AAV/HLA-engineering licence requiring that all products embodying or produced through the use of an
invention that is subject to the rights of the federal government of the United States of America shall be substantially manufactured in the United States of
America. Due to the nature of the product concerned, Universal understand that this may not always be commercially feasible and hence Universal agrees
to work with Adaptimmune and to approach the University on a timely basis during the performance of the Research Plan (as defined in the Research and
Collaboration Agreement) to obtain waiver from the University in relation to such manufacture and as permitted in accordance with 35 United States Code
Section 204.

5.3.2. Auditing Rights. Adaptimmune shall permit, at the request of University, one or more accountants selected exclusively by the University
(“Accountants”) to have access to Adaptimmune’s records and books of account pertaining to this Agreement, but not more than once per calendar year.
Accountants’ access will be during ordinary working hours to audit Adaptimmune’s records for any payment period ending prior to such request, the
correctness of any report or payment made by Universal under this Agreement, or to obtain information as to the payments due for any period in the case
of failure of Adaptimmune to report pursuant to the terms of this Agreement. Any such inspection shall be subject to Accountants signing confidentiality
agreements with Adaptimmune to ensure the confidentiality of Adaptimmune’s information. Access under this clause shall only be provided to records
relating to sales of Licensed Products and not to any other products or services. The cost of any audit under this clause shall be at the cost of the
University.

5.3.3. Scope of Disclosure. Accountants shall not disclose to University any information relating to the business of Adaptimmune except that which

is necessary to inform University of: the accuracy or inaccuracy of Adaptimmune’s reports provided to Universal under this Agreement (and which
Universal subsequently provides to University under the AAV/HLA-engineering licence); and the extent of any inaccuracy or noncompliance.

6. Infringement.

6.1. Third-Party Infringement of a Licensed Patent.

6.1.1. Notice of Third Party’s Infringement. If a Party learns of substantial, credible evidence that a Third Party is infringing a Licensed Patent in the

Field of Use in the Territory, that Party will promptly deliver written notice of the possible infringement to the other Party, describing in detail all
relevant information to which that

 
Party has access or control suggesting infringement of the Licensed Patent. Adaptimmune understands that under the terms of the AAV/HLA-
engineering licence, Universal is not able to grant a right to Adaptimmune to enforce the Licensed Patents. Universal will work with Adaptimmune in
relation to the exercise of Universal’s rights to enforce and prosecute an infringement or potential infringement action under the AAV/HLA-engineering
licence and to the extent permitted by the University, will permit Adaptimmune to be present at any court hearings, material meeting or other actions
taken in relation to enforcement of the Licensed Patents to the extent in each case relevant to the Fields of Use or scope of Research and Collaboration
Agreement. To the extent Universal proposes to settle any action for infringement or potential infringement, Universal will discuss and obtain
Adaptimmune’s approval to such settlement, such approval not to be unreasonably withheld or delayed. To the extent the University has control of any
infringement suit or action under the AAV/HLA-engineering licence, Universal will to the extent permitted by University keep Adaptimmune informed
of the progress of such infringement suit or action and permit Adaptimmune to be actively involved in such infringement suit or action including the
terms of any sublicense proposed to be granted by the University. Any involvement of Adaptimmune shall be at Adaptimmune’s cost and expense save
where University requests any assistance from Adaptimmune, in which case University shall pay for any direct associated expenses related to provision
of such assistance.

7. Patent Validity.

7.1. Notice and Investigation of Third Party Challenges. If any Third Party challenges the validity or enforceability of any of the Licensed Patents, the

Party having such information shall immediately notify the other Party. Universal shall keep Adaptimmune informed of the status of any defense of any
claim challenging validity or enforceability, where the University assumes control and defense of the claim in accordance with the terms of the AAV/HLA-
engineering licence. Where Universal assumes the defense of any such claim, Universal will cooperate with Adaptimmune and enable Adaptimmune to be
actively involved in the defense of such claim and any decisions taken in relation to such claim at Adaptimmune’s cost and expense.

following termination of the AAV/HLA-engineering licence, Adaptimmune may notify University and Universal that it wishes to enter into a direct license
with University in order to retain its rights to the Licensed Patents and/or Licensed Materials granted to it under its Sublicense (such 30-day period
following termination, the “Initial Notice Period”). Following receipt

 
of such notice, Universal shall procure (to the extent necessary under the AAV/HLA-engineering licence) that University and Adaptimmune shall enter into
a license agreement the terms of which shall be substantially similar to the terms of the AAV/HLA-engineering licence; and the scope of such direct
license, the licensed territory or the duration of the license grant shall be comparable to the corresponding terms granted under this Agreement; provided
that Adaptimmune will be granted at least the same scope of rights as it obtained from Adaptimmune under this Agreement. For the sake of clarity, the
financial terms, including without limitation, the running royalty rate and milestone payments, shall be identical to the corresponding financial terms set
forth in the AAV/HLA-engineering licence. Notwithstanding the foregoing, Adaptimmune understands that its right to enter into such direct license shall be
conditioned upon:

8.5.1. Written Notification to University. Adaptimmune informing University in writing, pursuant to Article 21 “Notices” of the AAV/HLA-

engineering licence, that it wishes to enter into such direct license with University, within the Initial Notice Period;

8.5.2. Good Standing. Adaptimmune being in good standing with Universal under this Agreement, and this Agreement not being the subject of a

dispute between Universal and Adaptimmune, or between Universal and University under the AAV/HLA-engineering licence;

“Sublicenses” of the AAV/HLA-engineering licence;

8.5.4. Sublicensee Certification that Conditions Satisfied. Adaptimmune using reasonable efforts to certify or otherwise demonstrate that the
conditions set forth in this Section 8.5 have been met within 30 days of expiration of the Initial Notice Period (or within such longer period of time as
University agrees is reasonable under the circumstances, based on the nature and extent of any documentation reasonably requested by University); and

8.5.5. Time Limitations. Such negotiations for a direct license not exceeding 90 days from the end of the 30-day (or longer, if applicable) period

described in subsection 8.5.4 “Sublicensee Certification that Conditions Satisfied” (subject to extension of said 90-day period by mutual written
agreement of University and Sublicensee).

University may, at its sole discretion, waive any of the above requirements. Adaptimmune understands and Universal confirms that if all of the conditions
set forth in this Section 8.5 are met, then Adaptimmune will be granted such direct license by University. If any condition set forth in this Section 8.5 is not
met, then after

 
expiration of any time period granted to Adaptimmune with respect to meeting such condition , Adaptimmune shall not make, have made, use, offer to sell
or sell, offer to lease or lease, import, or otherwise offer to dispose or dispose of Licensed Products and University shall be free to license or not license
Licensed Patents to Adaptimmune according to its sole discretion.

Information in non-written form, it shall reduce such communications to writing, clearly mark it “confidential”, and provide a copy to receiving Party
within 30 days of original communication at the address in Article 21 “Notices”.

14.2. No Unauthorized Disclosure of Confidential Information. Beginning on the Effective Date and continuing throughout the term of this Agreement

and thereafter for a period of 5 years, receiving Party shall not disclose or otherwise make known or available to any Third Party any disclosing Party
Confidential Information, without the express prior written consent of disclosing Party. Notwithstanding the foregoing, receiving Party shall be permitted
to disclose disclosing Party Confidential Information to (i) actual or potential investors, lenders, consultants, collaborators, sublicensees, or development
partners, which disclosure will be made under conditions of confidentiality and limited use and (ii) its attorney or agent as reasonably required. In no event

and if University concludes that the documents are not otherwise exempt from public disclosure, University will provide Universal notice of the request
before releasing such documents. Universal will provide such notice to Adaptimmune. Such notice will be provided in a timely manner to afford
Adaptimmune sufficient time to review such documents and/or seek a protective order to the extent agreed as necessary with Universal in good faith and
utilizing the procedures described in RCW 42.56.540

14.4. Disclosure as Required by Law. Either Party shall have the right to disclose the other Party’s Confidential Information as required by law or valid

court order, provided that such Party shall inform the Party who owns such Confidential Information prior to such disclosure and shall limit the scope and
recipient of disclosure to the extent required by such law or court order.

17. Enforceability.

If a court of competent jurisdiction adjudges a provision of this Agreement unenforceable, invalid, or void, such determination will not impair the

enforceability of any of the remaining provisions hereof and the provisions will remain in full force and effect.

18. No Third-Party Beneficiaries.

other designation of the other party, or the name of any faculty member, employee, or student of the other party, without prior written consent of
that party, unless such listing is required under local laws or regulations, provided that either party may state the existence of this Agreement. For
any use other than the foregoing, the parties hereby expressly agree not to use the other party’s name or the University’s name or any contraction,
abbreviation, or simulation thereof without prior written approval from an authorized representative of the relevant entity.

9. TERMINATION

9.1 Adaptimmune may terminate this Agreement by giving Universal notice in writing at least 30 days in advance of the effective termination date provided

that Adaptimmune, Sublicencees, and Service Partners shall thereupon cease use and sale of Biological Material and any Licensed Product(s).

9.2 Effect of Termination

9.2.1 Licensed Terminated - After termination of this Agreement, Adaptimmune shall not make, have made, use, offer to sell or sell, offer to lease
or lease, import, or otherwise offer to dispose or dispose of Licensed Products.

9.2.2 Concurrent with notice of termination by either Adaptimmune or Universal, Adaptimmune and Service Partners shall destroy all

provide written evidence of said destruction. If Adaptimmune enters into a direct license with Universal to retain rights in the Modifications under
Section 10.2.3

9.2.3 “Termination of Elf Licence. ”, Adaptimmune may retain Modifications and Licensed Product(s) in its possession during the Initial Notice
Period and negotiation period. At any time within 30 days following termination of the Elf Licence (notification of which to be immediately
provided by Universal to Adaptimmune), Adaptimmune may notify Universal and University that it wishes to enter into a direct license with
University in order to retain its rights to the Modifications granted to it under this Agreement (such 30-day period following termination, the “Initial
Notice Period”). Following receipt of such notice, University and Adaptimmune (and to the extent required Universal shall facilitate such
negotiations and finalization) shall enter into a license agreement the terms of which shall be substantially similar to the terms of the Elf Licence;
and the scope of such direct license, the licensed territory or the duration of the license grant shall be comparable to the corresponding terms granted
to Adaptimmune under this Agreement; provided that Adaptimmune will be granted at least the same scope of rights as it obtained from Universal
under this Agreement. For the sake of clarity, the financial terms, including without limitation, the running royalty rate and milestone payments,
shall be identical to the corresponding financial terms set forth in the Elf Licence. Universal shall keep Adaptimmune informed of all material
changes to the Elf Licence, including changes to the financial terms that Adaptimmune would be required to accept under this Section.
Notwithstanding the foregoing, each Adaptimmune’s right to enter into such direct license shall be conditioned upon:

10.2.3.1 Written Notification to University. Adaptimmune informing Universal and University in writing, pursuant to Article 11.4 “Notices”,

that it wishes to enter into such direct license with University, within the Initial Notice Period;

10.2.3.2 Adaptimmune Good Standing. Adaptimmune being in good standing with Universal under this Agreement, and this Agreement not

being the subject of a dispute between Adaptimmune and Universal, or between Universal and University under the Elf Licence (in which
case Universal shall have notified Adaptimmune of such dispute);

10.2.3.3 Valid Sublicense. This Agreement having been validly entered into by Adaptimmune and Universal pursuant to the terms of the Elf
Licence and the parties confirm and agree that this Agreeent has been validly entered into pursuant to the terms of the Elf Licence;

10.2.3.4 Certification that Conditions Satisfied. Adaptimmune using reasonable efforts to certify or otherwise demonstrate that the conditions

set forth in the above subsections subsections have been met within 30 days of expiration of the Initial Notice Period (or within such longer
period of

 
time as University agrees is reasonable under the circumstances, based on the nature and extent of any documentation reasonably
requested by University); and

10.2.3.5 Time Limitations. Such negotiations for a direct license not exceeding 90 days from the end of the 30-day (or longer, if applicable)

period described in subsection 9.2.3.2 “Adaptimmune Certification that Conditions Satisfied” (subject to extension of said 90-day period
by mutual written agreement of University and Adaptimmune). University may, at its sole discretion, waive any of these requirements. If
all of the conditions set forth in this Subsection 9.2.3 “Termination of Sublicenses” are met, then Adaptimmune will be granted such direct
license by University. If any condition set forth in this Section 10.2.3 “Termination of Sublicenses” is not met, then after expiration of any
time period granted to Adaptimmune with respect to meeting such condition, Adaptimmune shall not make, have made, use, offer to sell
or sell, offer to lease or lease, import, or otherwise offer to dispose or dispose of Licensed Products and University shall be free to license
or not license Licensed Patents to such Adaptimmune according to its sole discretion. Adaptimmune shall destroy all Modifications and
Licensed Product(s) in their possession, and shall provide written evidence of said destruction.

9.3 Breach by Adaptimmune. Universal may terminate this Agreement if Adaptimmune is in breach of any provision hereof and Adaptimmune fails to

remedy any such breach no later than 60 days after written notice thereof by Universal.

9.4 Survival. Immediately upon the termination of this Agreement all Adaptimmune’s rights under this Agreement will terminate; provided, however, That

the obligations and rights set forth in Sections 11.7 “Records Retention”, 11.8 “Audit Rights” and 10.2 “Effect of Termination” and Articles 6
“Release, Indemnification, and Insurance”, 7 “Warranties”, 8 “Damages”, 11.2 “Public Records Act”, 11.6 “Law and Venue” will survive the
termination of this Agreement.

This exclusive patent license and material transfer agreement (“Agreement”) is dated and effective as of the date of last signature (the “Effective

Date”), and is made between the University of Washington, a public institution of higher education and an agency of the state of Washington, acting
through its Center for Commercialization, Technology Licensing (“University”), and Universal Cells, a Corporation under the laws of the state of
Washington (“Company”), (individually “Party” or collectively “Parties”).

Background

Certain inventions and materials related to or useful for adeno-associated virus (AAV)-mediated gene targeting and HLA engineering were made

in the laboratory of David Russell (“Principal Investigator”) or for the materials, in the laboratory listed in Exhibit D “Materials”;

As assignee of the inventions, University owns certain patents and patent applications or jointly owns with a Third Party “Joint Owner” certain

patents and patent applications, as listed in Section A1 “Licensed Patents” of Exhibit A “Patent License Schedule”, and University has the right to license to
others certain rights to such patents and patent applications;

The “Joint Owner” of certain patents and patent applicatons, as listed in Section A1 “Licensed Patents” of Exhibit A, retains their own rights in

jointly owned Licensed Patents, and University is only licensing its own interest;

University’s rights in certain patents and patent applications listed in Section A1 “Licensed Patents” of Exhibit A “Patent License Schedule” have

been licensed to a third party prior to this Agreement on a co-exclusive basis, as defined below;

Company desires that University grant it a license to use, develop, and commercialize the Licensed Products; and

1.3. “Co-exclusive” for the purposes of this Agreement means, other than as provided for in Section 3.2 “The United States Government’s Rights”, and

Section 3.3 “University’s Reservation of Rights”, University will only grant licenses to a maximum of two separate parties.

1.4. “Group 2 Scope” means co-exclusive for the construction, sale and use of cell lines derived from Stem Cells using Group 2 Licensed Patents
specifically for: i) in vitro discovery and development of pharmaceutical agents; ii) in vitro discovery, development and validation of diagnostic targets; and
iii) in vitro development of engineered cell lines for bioproduction of pharmaceutical agents; exclusive for the development and use of therapeutic products
where the construction or manufacture of the therapeutic product itself utilized Group 2 Licensed Patents.

1.5. “Confidential Information” means any information or materials (biological, chemical, or otherwise) of the Parties not generally known to the

public, including any information comprised of those materials, and including without limitation the inventions covered by the Licensed Patents and
Company’s business plans or reports. Confidential Information does not include any information that:

 
1.5.1. is or becomes part of the public domain through no fault of receiving Party;

1.5.2. is known to receiving Party prior to the disclosure by the disclosing Party, as evidenced by documentation;

1.5.3. is publicly released as authorized under this Agreement by University, its employees or agents;

1.5.4. is subsequently obtained by a Party from a Third Party who is authorized to have such information; or

without any breach of this Agreement as evidenced by documentation.

1.6. “Event of Force Majeure” means an unforeseeable act that wholly prevents a Party from performing one or more of its material duties under this

Agreement and that is outside of the reasonable control of the Party. An Event of Force Majeure includes acts of war or of Nature, insurrection and riot,

1.7. “Fair Market Value” means [***]

.

1.8. “Product Family 1” means Licensed Products that are vectors or cell lines for research and development purposes. “Product Family 2” means

Schedule”, all divisionals and continuations of these patent applications, all patents issuing from these applications, divisionals, and continuations and any
reissues, reexaminations and extensions of these patents. Claims in continuations-in-part applications are included in Licensed Patents only to the extent
such claims are supported by a patent or patent application set forth in Section A1 “Licensed Patents” of Exhibit A “Patent License Schedule” to benefit
from the priority date of such patent or patent application and to the extent such claims are not encumbered by Third Party rights.

1.13. “Licensed Product” means any product or good or service that is used, made by, made for, sold, transferred, offered for sale, imported or

execution. Company shall not enter into such agreement if the terms of the agreement are inconsistent in any respect with the material terms of this
Agreement. Any Sublicense made in violation of this Subsection will be void and will constitute an event of default under Subsection 9.1.1 “Breach by
Company”.

 
3.1.6. The license granted in this Agreement is limited to the inventions that are expressly claimed in the Licensed Patents. No provision of this
Agreement grants Company, by implication, estoppel or otherwise, any rights other than the rights expressly granted it in this Agreement to the Licensed
Patents, Licensed Materials, or to any other University-owned technology, materials, patent applications, or patents.

3.2. The United States Government’s Rights. The inventions covered in the Licensed Patents arose, in whole or in part, from federally supported
research and the federal government of the United States of America has certain rights in and to the Licensed Patents as those rights are described in
Chapter 18, Title 35 of the United States Code and accompanying regulations, including Part 401, Chapter 37 of the Code of Federal Regulation. The
Parties’ rights and obligations under this Agreement to any government-funded inventions, including the grant of license set forth in Subsections 3.1.1

7.1.1. Company’s First Right to Settle. During the term of this Agreement, Company has the first right to respond to, defend, and prosecute in its
own name and at its own expense actions or suits relating to exclusively Licensed Patents. To enjoy said first right, Company must initiate bona fide
action to respond to any alleged infringement within 90 days of learning of said infringement. If required by law, University agrees to be joined as a
party plaintiff; provided that Company must notify University at least 10 days before filing suit and provided that Company shall reimburse University
for all reasonable legal fees and costs incident thereto. Company shall not settle any suits or actions in any manner relating to the Licensed Patents
without obtaining the prior written consent of University. University will work with Company and Third Party Co-Licensee to determine the best course
of action for dealing with infringement of Group 2 Licensed Patents.

suit, or settlement for infringement of Licensed Patents. Any remaining proceeds will be distributed as follows: Company shall retain [***]%
and shall distribute [***]% to University. Any payment by an alleged infringer that constitutes consideration for Net Sales of infringing
product, however, will be handled according to the payment provisions of Article 6 “Payments, Reimbursements, Reports, and Records” and
Section A3.1 “Running Royalty Payments” of Exhibit A “Patent License Schedule”. Any payment by an alleged infringer that constitutes
consideration for the grant of a Sublicense will be handled according to Section A3.8 “Sublicensing Consideration” of Exhibit A “Patent
License Schedule”.

7.1.1.2. Limitation on Infringement Actions. Excluded from the rights granted herein is the right to bring an infringement action against any
inventor or their present or future not-for-profit employers, for infringement of the Licensed Patents in carrying out not-for-profit research.

 
7.1.2. University Right to Institute Action. If Company has first right to pursue infringers and fails, within 90 days of learning of an alleged

infringement, to secure cessation of the infringement, institute suit against the infringer, or to provide to University satisfactory evidence that Company is
engaged in bona fide negotiations for the acceptance by infringer of a Sublicense in and to relevant patents in Licensed Patents for the Field of Use, then
University may, upon written notice to Company, assume full right and responsibility to secure cessation of the infringement, institute suit against the
infringer, or secure acceptance of a Sublicense by Company from the alleged infringer in and to relevant patents in Licensed Patents. Such license shall
not be subject to Company’s approval. If University, in accordance with the terms and conditions of this Agreement, chooses to institute suit against an
alleged infringer, University may bring such suit in its own name (or, if required by law, in its and Company’s name) and at its own expense, and
Company shall, but at University’s expense for Company’s direct associated expenses, fully and promptly cooperate and assist University in connection
with any such suit. All license fees, royalties, damages, awards, or settlement proceeds arising from a University-initiated action will be solely for the
account of University.

Licensed Patents, University, at its sole discretion, shall have the right to assume and control the sole defense of the claim at University’s expense. If
University opts not to assume and control the sole defense of the claim within 30 days after becoming aware of challenge, Company shall have the right to
assume the defense of the claim at its own expense. Company shall not settle any suits or actions in any manner relating to the Licensed Patents without
obtaining the prior written consent of University.

8.3. Enforceability of Licensed Patents. Notwithstanding challenge by any Third Party, any Licensed Patent will be enforceable under this Agreement

until such Licensed Patent is determined to be invalid.

payable upon termination or expiration.

9.3.3. Termination of Sublicenses. At any time within 30 days following termination of this Agreement, a Sublicensee may notify University that it
wishes to enter into a direct license with University in order to retain its rights to the Licensed Patents and/or Licensed Materials granted to it under its
Sublicense (such 30-day period following termination, the “Initial Notice Period”). Following receipt of such notice, University and Sublicensee shall
enter into a license agreement the terms of which shall be substantially similar to the terms of this Agreement; and the scope of such direct license, the
licensed territory or the duration of the license grant shall be comparable to the corresponding terms granted by the Company to such Sublicensee;
provided that such Sublicensee will be granted at least the same scope of rights as it obtained from Company under its Sublicense. For the sake of
clarity, the financial terms, including without limitation, the running royalty rate and milestone payments, shall be identical to the corresponding
financial terms set forth in this Agreement. Notwithstanding the foregoing, each Sublicensee’s right to enter into such direct license shall be conditioned
upon:

 
9.3.3.1. Written Notification to University. Such Sublicensee informing University in writing, pursuant to Article 21 “Notices”, that it wishes to
enter into such direct license with University, within the Initial Notice Period;

the conditions set forth in subsections 9.3.3.1 “Written Notification to University”, 9.3.3.2 “Sublicensee Good Standing”, and 9.3.3.3 “Valid
Sublicense” have been met within 30 days of expiration of the Initial Notice Period (or within such longer period of time as University agrees is
reasonable under the circumstances, based on the nature and extent of any documentation reasonably requested by University); and

9.3.3.5. Time Limitations. Such negotiations for a direct license not exceeding 90 days from the end of the 30-day (or longer, if applicable)
period described in subsection 9.3.3.4 “Sublicensee Certification that Conditions Satisfied” (subject to extension of said 90-day period by
mutual written agreement of University and Sublicensee).

University may, at its sole discretion, waive any of these requirements. If all of the conditions set forth in this Section 9.3.3 “Termination of
Sublicenses” are met, then Sublicensee will be granted such direct license by University. If any condition set forth in this Section 9.3.3
“Termination of Sublicenses” is not met, then after expiration of any time period granted to Sublicensee with respect to meeting such condition
(for example and to the extent applicable, the Initial Notice Period and/or the periods described in Subsections 9.3.3.4 “Sublicensee
Certification that Conditions Satisfied” and 9.3.3.5 “Time Limitations”), Sublicensee shall not make, have made, use, offer to sell or sell, offer
to

 
lease or lease, import, or otherwise offer to dispose or dispose of Licensed Products and University shall be free to license or not license
Licensed Patents to such Sublicensee according to its sole discretion.

SUBSCRIPTION AGREEMENT

SUBSCRIPTION AGREEMENT, dated the date indicated below on the signature page hereof, by and between the Company and the University.
If and when accepted by the Company, this Subscription Agreement, when executed below, shall constitute a subscription for that number of shares of the
Securities indicated on the attached Appendix A. All capitalized terms are defined on Appendix A.

INTENDING TO BE LEGALLY BOUND, and in consideration of the mutual representations, warranties, covenants and agreements contained

herein, Company and University hereby agree as follows:

1. Representations and Warranties of the University. The University hereby represents and warrants to the Company as of the date of this

Agreement as follows:

1.1 The University: (a) is an Accredited Investor as that term is defined in 17 CFR § 230.501(a); (b) has been furnished with all

information deemed necessary by the University to evaluate the merits and risks of the Securities; (c) has had the opportunity to ask questions and receive
answers concerning the Company and the Securities; and (d) has been given the opportunity to obtain any additional information necessary to verify the
accuracy of any information obtained concerning the Company.

withstand a complete loss of the investment in the Securities.

1.2 Ability to Bear Risk. The University is in a financial position to hold the Securities and is able to bear the economic risk and

1.3 Risk Factors. The University recognizes that the Securities as an investment involve an extremely high degree of risk. There can be

no assurance that the Company will be able to meet its projected goals and the Company may need significant additional capital to be successful, which
capital may not be readily

 
available or available upon terms that are not substantially dilutive to the University. If provided, the University has reviewed the risk factors description
provided by the Company.

1.4. Sophistication. The University is a sophisticated investor, is able to fend for itself in the transactions contemplated by this Agreement,

and has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of the prospective investment
in the Securities.

1.5. Suitability. The investment in the Securities is suitable for the University based upon its investment objectives and financial needs,

and the University has adequate net worth and means for providing for its current financial needs and contingencies and has no need for liquidity of
investment with respect to the Securities.

marketable is not disproportionate to its net worth, and investment in the Securities will not cause such overall commitment to become excessive.

1.6. Overall Commitment to Illiquid Investments. The University’s overall commitment to investments which are illiquid or not readily

1.7. Restricted Securities. The University realizes that (i) none of the Securities have been registered under the Securities Act of 1933, as
amended (the “Act”), (ii) the Securities are characterized under the Act as “restricted securities” and, therefore, cannot be sold or transferred unless they are
subsequently registered under the Act or an exemption from such registration is available and (iii) there is presently no public market for the Securities and
the University may not be able to liquidate his investment in the event of an emergency or pledge the Securities as collateral security for loans. In this
connection, the University represents that it is familiar with Rule 144 promulgated under the Act, and understands the resale limitations imposed thereby
and by the Act.

1.8. Exemption Reliance. The University has been advised that the Securities are not being registered under the Act or the applicable

state securities laws but are being offered and sold pursuant to exemptions from such laws. The University understands that the Company’s reliance on such
exemptions is predicated in part upon the truth and accuracy of the University’s representations in this Agreement. The University represents and warrants
that the Securities are being purchased for its own account, for investment and without the intention of reselling, redistributing or transferring the same, that
it has made no agreement with others regarding any of such Securities and that its financial condition is such that it is not likely that it will be necessary to
dispose of any of such Securities in the foreseeable future.

 
2. Covenants. The University agrees that:

with all applicable laws.

2.1. Transfer Restriction. The Securities for which the University hereby subscribes shall be assigned or transferred only in accordance

purchasing unless and until:

2.2. Disposition of Securities. The University shall in no event make any disposition of all or any portion of the Securities which it is

in accordance with said registration statement; or

a. There is then in effect a registration statement under the Act covering such proposed disposition and such disposition is made

registration of such shares under the Act, and (ii) such opinion of its counsel shall have been concurred in by counsel for the Company, such concurrence
not to be unreasonably withheld or delayed, and the Company shall have advised the University of such concurrence; or

b. (i) It shall have furnished the Company with an opinion of its own counsel to the effect that such disposition will not require

amended, or is otherwise exempt from the registration requirements of such act.

c. The transfer shall comply with the applicable requirements of Rule 144 as promulgated under the Securities Act of 1933, as

successors and assigns.

2.3. No Revocation. The University may not cancel, terminate or revoke this subscription, and this subscription shall be binding upon its

Company and executed by other investors in Company that contain solely one or more of the following provisions:

2.4 Execution of Related Documents. The University agrees to execute other customary, investment-related agreements as proposed by

· General prohibition on transfer of the Securities

 
· Right of first refusal on proposed transfer

· Right of co-sale on proposed transfer

· “Tag along, drag along” rights (both must be included)

THIS AGREEMENT  (“Agreement”) is dated and effective as of the date of last signature (“Effective Date”), and is made by and between the University
of Washington, a public institution of higher education and an agency of the state of Washington acting through its administrative offices at UW Center for
Commercialization, 4311 Eleventh Avenue NE, Suite 500, Seattle, WA 98105 (“University”), and Universal Cells, a Corporation under the laws of the
state of Washington (“Company”), agree as follows:

1. BACKGROUND

1.1 University has certain rights to Biological Material known as New naive human embryonic stem cell line - Elf1 (as defined in Section 2.1), developed in

the laboratory of Dr. Carol Ware.

1.2 University desires to have Biological Material marketed at the earliest possible time in order that products resulting therefrom may be available for public

use and benefit.

1.3 Company has previously entered into an exclusive license agreement with University for inventions and materials related to or useful for Adeno-

associated virus (AAV)-mediated gene targeting and HLA engineering, UW Ref # 34243A on June 27, 2014 “Exclusive Agreement”.

1.4 Company wishes to acquire a license to said Biological Material to make, use, and sell Licensed Product(s) in the Internal Research Field of Use and

Product Field of Use.

2. DEFINITIONS

2.1 “Biological Material” means New naive human embryonic stem cell line - Elf1 (with a University Reference UW # 45910).

2.2 “Internal Research Field of Use” means internal research. Internal Research Field of Use specifically excludes any use which requires regulatory

approval, including any in vitro and in vivo diagnostic or therapeutic applications.

2.3 “Product Field of Use” means in vivo therapeutics excluding any therapeutic agent for cardiac regeneration and cardiovascular disease.

 
2.4 “Licensed Product” means any product or good or service that is a Modification and is used, made by, made for, sold, transferred, offered for sale,

imported or otherwise disposed of during the term of this Agreement..

2.5 “Licensed Territory” means worldwide.

2.6 “Modifications” means any derivatives or modifications of Biological Material that, but for the rights granted under Exclusive Agreement, would

otherwise infringe a Valid Claim of Groups 2 and 3 Licensed Patents as defined in Exclusive Agreement as originally executed. Modifications
generated at University and to be provided to Company are listed in Section A1 “UW Materials to be Delivered” in Exhibit A.

2.7 [***]

 
2.8 “Product Family 1” means Licensed Products in which Company receives no further consideration (including but not limited to royalties and/or

commissions) beyond the price for the initial sale and limited to sales to end-users for research and development purposes. “Product Family 2”
means Licensed Products that requires regulatory approval, including any in vitro and in vivo diagnostic or therapeutic applications.

2.9 “Service Partner” means a legal entity that is a Third Party with whom Licensee has contracted to provide services within the Internal Research Field of
Use and Product Field of Use. For clarity, a legal entity is only a Service Partner for so long as the definition remains true. If such entity terminates
its contractual obligation with Licensee, it thereafter is an arm-length Third Party for the purposes of this Agreement.

2.10 “Sublicense” means the grant by Company to a Third Party of any license, option, first right to negotiate, or other right granted in the Licensed Products,
in whole or in part. For the avoidance of doubt, any sale of a Licensed Product by Company or Sublicensee to an arm’s length Third Party distributor
(“Distributor”) for resale of Licensed Product by the Distributor, and where Distributor has no other rights other than to resell Licensed Product, and
for which resale Company and Sublicensees receive no further consideration (including but not limited to royalties and/or commissions) beyond the
price for the initial sale to the Distributor shall be considered a sale, and shall not be a considered a Sublicense.

2.11 “Sublicensee” means a Third Party holding a Sublicense under the Modifications.

2.12 “Sublicensing Consideration” means all consideration, including but not limited to upfront fees, milestone payments, maintenance fees, non-cash

consideration, and premiums over Fair Market Value of stock, but excluding royalties, payable by each Sublicensee for the grant of a Sublicense.
For avoidance of doubt, consideration paid to Company by Sublicensees for the performance of bona fide product development work, research
work, clinical studies and regulatory approvals performed by Company, pursuant to and as supported by an express agreement including a
performance plan and commensurate budget is not deemed to be Sublicensing Consideration.

 
2.13 “Third-Party” means any individual or entity other than University and Company.

3. GRANT

3.1 University hereby grants, and Company accepts, a nonexclusive license to make and use Biological Material for Internal Research Field of Use only.

Company shall not transfer Biological Material to any Third-Party, including Sublicencee(s) for any purpose.

3.2 University hereby grants, and Company accepts, a nonexclusive license in the (i) Product Field of Use and Licensed Territory to make, use, offer, and sell

Licensed Product(s) for Product Family 2 and (ii) make, use, offer, and sell Licensed Products in the Internal Research Field of Use for Product
Family 1.

3.3 Service Partners of Licensee. Licensee shall have the right to transfer Modifications to Service Partners working on behalf of Licensee solely for the

purpose of carrying out services in direct connection with using the Modifications in the Internal Field of Use and Product Field of Use. Any such
transfer of Modifications to such Service Partner shall be under a written agreement between Licensee and such Service Partner which (a) shall be
in writing, (b) shall be subject to, subordinate to, and consistent with, the terms and conditions of this Agreement, (c) shall not adversely affect the
rights of University or limit the obligations of Licensee under this Agreement, (d) shall contain terms substantially similar to those contained in this
Agreement, and (e) shall expressly provide that the Service Partner has no rights to use the Modifications for any purpose other than to perform the
services in direct connection with the Licensed Field of Use, and that such Service Partner shall not transfer the Modifications to any Third-Party.
Licensee will be responsible for the performance of all Service Partner in compliance with all obligations of Licensee under this Agreement. For
purposes of clarity, Company has no right to transfer Biological Material to Service Partners.

3.4 Sublicenses. Company has the right, exercisable from time to time during the term of this Agreement, to Sublicense its rights in the Product Field of Use
granted in Paragraph 3.2 of this Agreement, including for evaluation of the suitability of Licensed Products as a therapeutic product for limited time
periods

 
(“Evaluation Period”). Said right does not include the right to transfer Licensed Products(s) to Third Parties or affiliates for resale other than as
incorporated in a therapeutic product. Company shall remain responsible for its obligations under this Agreement, and shall ensure that the
Sublicense agreement: i) contains terms and conditions requesting Sublicensee to comply with the applicable terms and conditions under this
Agreement (including a release substantially similar to that provided by Company in Section 6.1 “Company’s Release”; a warranty substantially
similar to that provided by Company in Section 7.1 “Authority”; University disclaimers and exclusions of warranties under Subsections 7.2
“Disclaimers”; and limitations of remedies and damages substantially similar to those provided by Company in Sections 8.1 “Remedy Limitation”
and 8.2 “Damage Cap”); and (ii) specifically incorporates provisions of this Agreement regarding obligations pertaining to indemnification, use of
names and insurance. Company shall deliver to University a true, correct, and complete copy of any Sublicense agreement or other agreement under
which Company grants sublicensing rights, within 30 days of its execution. Company shall not enter into such agreement if the terms of the
agreement are inconsistent in any respect with the material terms of this Agreement. Any Sublicense made in violation of this Subsection will be
void and will constitute an event of default under Subsection 10.3 “Breach by Company”. For avoidance of doubt, Company has no right to
Sublicense Biological Material.

period following termination, the “Initial Notice Period”). Following receipt of such notice, University and Sublicensee shall enter into a license
agreement the terms of which shall be substantially similar to the terms of this Agreement; and the scope of such direct license, the licensed territory
or the duration of the license grant shall be comparable to the corresponding terms granted by the Company to such Sublicensee; provided that such
Sublicensee will be granted at least the same scope of rights as it obtained from Company under its Sublicense. For the sake of clarity, the financial
terms, including without limitation, the running royalty rate and milestone payments, shall be identical to the corresponding financial terms set forth
in this Agreement. Notwithstanding the foregoing, each Sublicensee’s right to enter into such direct license shall be conditioned upon:

10.2.3.1 Written Notification to University. Such Sublicensee informing University in writing, pursuant to Article 11.4 “Notices”, that it wishes

to enter into such direct license with University, within the Initial Notice Period;

 
10.2.3.2 Sublicensee Good Standing. Such Sublicensee being in good standing with Company under its Sublicense, and such Sublicense not

being the subject of a dispute between Sublicensee and Company, or between Company and University under this Agreement;

10.2.3.3 Valid Sublicense. Such Sublicense having been validly entered into by Company and Sublicensee pursuant to the terms of Subsection

3.4 “Sublicenses”;

10.2.3.4 Sublicensee Certification that Conditions Satisfied. Such Sublicensee using reasonable efforts to certify or otherwise demonstrate that
the conditions set forth in Subsections 10.2.3.1 “Written Notification to University”, 10.2.3.2 “Sublicensee Good Standing”, and 10.2.3.4
“Valid Sublicense” have been met within 30 days of expiration of the Initial Notice Period (or within such longer period of time as
University agrees is reasonable under the circumstances, based on the nature and extent of any documentation reasonably requested by
University); and

 
10.2.3.5 Time Limitations. Such negotiations for a direct license not exceeding 90 days from the end of the 30-day (or longer, if applicable)

period described in subsection 10.2.3.2 “Sublicensee Certification that Conditions Satisfied” (subject to extension of said 90-day period by
mutual written agreement of University and Sublicensee).

University may, at its sole discretion, waive any of these requirements. If all of the conditions set forth in this Subsection 10.2.3
“Termination of Sublicenses” are met, then Sublicensee will be granted such direct license by University. If any condition set forth in this
Section 10.2.3 “Termination of Sublicenses” is not met, then after expiration of any time period granted to Sublicensee with respect to
meeting such condition (for example and to the extent applicable, the Initial Notice Period and/or the periods described in Subsections
10.2.3.4 “Sublicensee Certification that Conditions Satisfied” and 10.2.3.5 “Time Limitations”), Sublicensee shall not make, have made,
use, offer to sell or sell, offer to lease or lease, import, or otherwise offer to dispose or dispose of Licensed Products and University shall
be free to license or not license Licensed Patents to such Sublicensee according to its sole discretion . Sublicensee shall destroy all
Modifications and Licensed Product(s) in their possession, and shall provide written evidence of said destruction.

10.2 Company shall make a written report to University no later than 90 days after the date of termination of this Agreement, stating the number, description,

and Net Sales of all Licensed Products ever made, sold, or otherwise disposed of and upon which royalties are payable hereunder but which were
not previously reported to University for any reason.

10.3 Breach by Company. University may terminate this Agreement if Company is in breach of any provision hereof and Company fails to remedy any such

breach no later than 60 days after written notice thereof by University.

10.4 Survival. Immediately upon the termination of this Agreement all Company’s rights under this Agreement will terminate; provided, however,

Company’s obligations that have accrued prior to the effective date of

 
termination of this Agreement (e.g., the obligation to report and make payments on sales, leases, or dispositions of Licensed Products ) and the
obligations specified in Sections 4.1 “Payments” and 4.2 “Sales Reports” will survive. The obligations and rights set forth in Sections 11.7
“Records Retention”, 11.8 “Audit Rights” and 10.2 “Effect of Termination” and Articles 6 “Release, Indemnification, and Insurance”, 7
“Warranties”, 8 “Damages”, 11.2 “Public Records Act”, 11.6 “Law and Venue” will survive the termination of this Agreement.

sufficient time to review such documents and/or seek a protective order, at Company’s expense utilizing the procedures described in RCW
42.56.540. University shall have no obligation to protect the confidential information from disclosure in response to a request for public records.

11.3 Assignment —  Company shall not assign this Agreement to a Third Party without the express written consent of University, except that Company may

assign or otherwise transfer this Agreement and the license granted hereby and the rights acquired by it hereunder so long as such assignment or
transfer is accompanied by a sale or other transfer of Company’s entire business or of the entirety of that part of Company’s business to which the
license granted hereby relates, including a change of control. Company shall provide written notice to University of such assignment and transfer no
later than ten (10) days after

 
the close of the transaction pursuant to which such assignment is made. Upon such assignment or transfer, the term “Company” as used in this
Agreement will include such assignee or transferee and this Agreement will be binding upon Company’s permitted successors and assigns. Any
attempted assignment, transfer or delegation in breach of this provision will be deemed void and will entitle University to terminate this Agreement
