SPECIAL CAUTIONARY NOTICE REGARDING FORWARD-LOOKING STATEMENTS

This Annual Report on Form 10-K contains “forward-looking statements” as defined under federal securities laws.
Forward-looking statements are based on our current expectations of future events and many of these statements can be
identified using terminology such as “believes,” “expects,” “anticipates,” “plans,” “may,” “will,” “projects,” “continues,”
“estimates,” “potential,” “opportunity” and similar expressions. These forward-looking statements, which include, but are
not limited to, statements related to the COVID-19 coronavirus pandemic, our collaboration and license agreements, our
beliefs  about  our  competitive  advantage  and  the  capabilities  of  our  manufacturing  facility,  our  cash  runway,  the
advancement of our clinical trials, our intellectual property portfolio, and the impact of regulatory actions on our regulatory
submission  timelines,  may  be  found  in  Part  I,  Item  1  “Business,”  Part  1,  Item  1A  “Risk  Factors,”  Part  II,  Item  7
“Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations”  and  other  sections  of  this
Annual Report on Form 10-K.

Forward-looking  statements  are  only  predictions  based  on  management’s  current  views  and  assumptions  and
involve  risks  and  uncertainties,  and  actual  results  could  differ  materially  from  those  projected  or  implied.  The  most
significant factors known to us that could materially adversely affect our business, operations, industry, financial position
or future financial performance include those discussed in Part I, Item 1A “Risk Factors,” as well as those discussed in Part
II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in this
Annual Report on Form 10-K, as well as other factors which may be identified from time to time in our other filings with
the  Securities  and  Exchange  Commission  (“SEC”),  or  in  the  documents  where  such  forward-looking  statements  appear.
You should carefully consider that information before you make an investment decision.

You  should  not  place  undue  reliance  on  these  forward-looking  statements,  which  speak  only  as  of  the  date  that
they were made. Our actual results or experience could differ significantly from those anticipated in the forward-looking
statements  and  from  historical  results,  due  to  the  risks  and  uncertainties  described  in  this  Annual  Report  on  Form  10-K
including in “Part I, Item 1A. “Risk Factors,” as well as others that we may consider immaterial or do not anticipate at this
time. These cautionary statements should be considered in connection with any written or oral forward-looking statements
that we may make in the future or may file or furnish with the SEC. We do not undertake any obligation to release publicly
any revisions to these forward-looking statements after completion of the filing of this Annual Report on Form 10-K to
reflect later events or circumstances or to reflect the occurrence of unanticipated events. All forward-looking statements
attributable to us are expressly qualified in their entirety by these cautionary statements.

In  addition,  with  respect  to  all  our  forward-looking  statements,  we  claim  the  protection  of  the  safe  harbor  for

forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.

Summary Risk Factors

The following is a summary of the principal risks associated with an investment in our ordinary shares:

● Our business, operations and supply chain have been, and may continue to be, materially and adversely affected

by the ongoing Covid pandemic.

● We have encountered, and may continue to encounter, delays in, and impediments to the progress of our clinical

trials or fail to demonstrate the safety and efficacy of our product candidates.

● We  may  not  be  successful  in  our  efforts  to  use  our  gene  therapy  technology  platform  to  build  a  pipeline  of
additional  product  candidates,  and  we  may  not  be  successful  in  our  efforts  to  create  innovative  programs,
platform technologies or other technologies to be competitive with others.

● We may not be successful in our efforts to in-license or acquire product candidates that align with our research

and development strategy.

● Our manufacturing facility is subject to significant government regulations and approvals. If we fail to comply

with these regulations or to maintain these approvals our business could be materially harmed.

● Our  resources  might  be  adversely  affected  if  we  are  unable  to  successfully  complete  pre-approval  inspections
required  by  regulators  or  meet  our  supply  needs  and  obligations,  which  could  adversely  affect  our  ability  to
sufficiently meet our future production needs or regulatory filing or approval timelines.

● We cannot predict when or if we will obtain marketing approval to commercialize any of our product candidates,

or whether they will be commercially successful once approved.

● We  are  exposed  to  a  number  of  external  factors  such  as  competition,  insurance  coverage  of  and  pricing  and
reimbursement for our product candidates that may adversely affect our product revenue and that may cause our
business  to  suffer.  We  also  have  experienced  and  could  continue  to  experience  increased  competition  for  and
compensation  expenses  associated  with  employee  recruiting  and  employee  retention,  which  could  adversely
affect our business.

● If we are unable to successfully commercialize our product candidates or experience significant delays in doing

so, our business could be materially harmed.

● We rely, and expect to continue to rely, on third parties to conduct, supervise, and monitor our preclinical studies
and clinical trials, and those third parties may not perform satisfactorily, including failing to meet deadlines for
the completion of such trials or failing to comply with regulatory requirements.

● We rely on licenses of intellectual property from third parties, and such licenses may not provide adequate rights
or may not be available in the future on commercially reasonable terms or at all, and our licensors may be unable
to obtain and maintain patent protection for the technology or products that we license from them.

● If we are unable to obtain and maintain patent protection for our technology and products, or if the scope of the
patent  protection  is  not  sufficiently  broad,  our  ability  to  successfully  commercialize  our  products  may  be
impaired.

● Our reliance on third parties may require us to share our trade secrets, which could increase the possibility that a

competitor will discover them or that our trade secrets will be misappropriated or disclosed.

● Our  acquisition  strategy  may  not  produce  the  cash  flows  expected  or  could  result  in  additional  costs  and

challenges.

● We will likely need to raise additional funding, which may not be available on acceptable terms, or at all. Failure
to obtain capital when needed may force us to delay, limit or terminate our product development efforts or other
operations which could have a material adverse effect on our business, financial condition, results of operations,
and cash flows.

● Our relationships with customers and third-party payers will be subject to applicable anti-kickback, anti-bribery,
fraud and abuse and other laws and regulations, which, if we are found in violation thereof, could expose us to
criminal  sanctions,  civil  penalties,  contractual  damages,  reputational  harm  and  diminished  profits  and  future
earnings.

Table of Contents

● We  are  subject  to  laws  governing  data  protection  in  the  different  jurisdictions  in  which  we  operate.  The
implementation  of  such  data  protection  regimes  is  complex,  and  should  we  fail  to  fully  comply,  we  may  be
subject to penalties that may have an adverse effect on our business, financial condition, and results of operations.

● Our internal computer systems, or those of our collaborators or other contractors or consultants, may fail or suffer
security  breaches  or  other  errors  or  disruptions,  which  could  result  in  a  material  disruption  of  our  product
development programs, such as potential issues with data integrity or loss of data.

● If we fail to maintain an effective system of internal controls, we may be unable to accurately report our results of
operations or prevent fraud or fail to meet our reporting obligations, and investor confidence and the market price
of our ordinary shares may be materially and adversely affected.

Item 1.  Business.

Overview

We  are  a  leader  in  the  field  of  gene  therapy  and  seek  to  deliver  to  patients  suffering  from  rare  and  other
devastating diseases single treatments with potentially curative results. We are advancing a focused pipeline of innovative
gene therapies, including product candidates for the treatment of hemophilia B, which effective May 6, 2021, we licensed
to  CSL  Behring  pursuant  to  the  CSL  Behring  Agreement  (as  defined  below),  and  Huntington’s  disease.  We  believe  our
technology platform and manufacturing capabilities provide us distinct competitive advantages, including the potential to
reduce development risk, cost, and time to market. We produce our Adeno-associated virus (“AAV”) -based gene therapies
in  our  own  facilities  with  a  proprietary,  commercial-scale,  current  good  manufacturing  practices  (“cGMP”)-compliant,
manufacturing process. We believe our Lexington, Massachusetts-based facility is one of the world’s most versatile gene
therapy manufacturing facilities.

Key events

Acquisition of Corlieve Therapeutics

On June 21, 2021, we entered into a share and purchase agreement (“SPA”) to acquire all outstanding ordinary
shares of Corlieve Therapeutics SAS (“Corlieve”), a privately held French gene therapy company (together, the “Corlieve
Transaction”). Upon the closing of the Corlieve Transaction on July 30, 2021 (“Acquisition Date”), we acquired 97.7% of
the outstanding ordinary shares of Corlieve in return for EUR 44.9 million ($53.3 million as of the Acquisition Date). As
contractually required in the SPA, we acquired the remaining outstanding ordinary shares on February 9, 2022 following
the expiration of a minimum holding period (“Mandatorily Redeemable Shares”). We recorded a liability related to these
Mandatorily Redeemable Shares for an amount of EUR 0.7 million ($0.9 million) as of the Acquisition Date. We financed
the Corlieve Transaction from cash on hand.

Following  its  formation  in  November  2019,  Corlieve  obtained  exclusive  licenses  to  certain  patents  from  two
French research institutions that continue to collaborate with Corlieve and us. Corlieve also obtained an exclusive license
from  Regenxbio  Inc.  (“Regenxbio”)  for  the  use  of  AAV9  to  deliver  any  sequence  that  affects  the  expression  of  the
Glutamate  inotropic  receptor  kainate  type  subunit  2  (“GRIK  2”)  gene  sequence  in  humans.  Corlieve  and  Regenxbio
simultaneously entered into a collaboration plan related to agreed joint preclinical research and development activities. At
the Acquisition Date, Corlieve and its Swiss subsidiary, Corlieve Therapeutics AG, employed seven employees.

Corlieve’s gene therapy program, AMT-260, employs micro ribonucleic acid (“miRNA”) silencing technology to
target  suppression  of  aberrantly  expressed  kainate  receptors  in  the  hippocampus  of  patients  with  temporal  lobe  epilepsy
(“TLE”). TLE affects approximately 1.3 million people in the U.S. and Europe alone, of which approximately 0.8 million
patients  are  unable  to  adequately  control  acute  seizures  with  currently  approved  anti-epileptic  therapies.  Patients  with
refractory TLE experience increased morbidity, excess mortality, and poor quality of life.

In addition to the payments to acquire 100% of the outstanding ordinary shares, Corlieve’s former and remaining
shareholders  are  eligible  to  receive  up  to  EUR  35.8  million  (or  $40.6  million  as  of  December  31,  2021)  upon  the
achievement of development milestones through Phase I/II and EUR 143.1 million (or $162.3 million as of December 31,
2021) upon the achievement of milestones associated with Phase III development and obtaining approval to commercialize
AMT-260  in  the  United  States  of  America  and  the  European  Union.  We  may  elect  to  pay  up  to  25%  of  such  milestone
payments through the issuance of our ordinary shares. We recorded a EUR 20.2 million ($24.0 million) liability related to
these contingent consideration payments as of the Acquisition Date.

Table of Contents

Total consideration of EUR 65.8 million ($78.1 million), which consisted of the cash paid upon the Acquisition
Date,  the  payment  for  the  Mandatorily  Redeemable  Shares  and  the  contingent  consideration  payments,  was  allocated  to
identifiable intangible assets related to the in-process research and development of AMT-260 (“IPR&D Intangible Asset”).
The IPR&D Intangible Asset’s fair value was determined at EUR 53.6 million ($63.6 million) as of the Acquisition Date.
We also recognized a EUR 13.4 million ($15.9 million) deferred tax liability in relation to this IPR&D Intangible Asset.
The  total  consideration  in  excess  of  the  net  assets  acquired  was  EUR  23.9  million  ($28.4  million)  and  was  allocated  to
goodwill.

CSL Behring commercialization and license agreement

On June 24, 2020, (the “Signing Date”), uniQure biopharma B.V., a wholly-owned subsidiary of uniQure N.V.,
entered into a commercialization and license agreement (as amended, the “CSL Behring Agreement”) with CSL Behring
LLC (“CSL Behring”) pursuant to which CSL Behring received exclusive global rights to etranacogene dezaparvovec, our
investigational gene therapy for patients with hemophilia B (the “Product”).

The  transaction  became  fully  effective  on  May  6,  2021,  one  day  after  the  waiting  period  under  the  Hart-Scott-

Rodino Antitrust Improvements Act of 1976 (the “HSR Act”) expired on May 5, 2021.

CSL Behring is responsible for the development and commercialization of the Product. We agreed to complete the
validation  of  the  current  manufacturing  process  as  well  as  to  the  development  and  validation  of  a  next  generation
manufacturing process. We will be entitled to receive a development milestone payment if we complete these activities in
accordance with an agreed development plan and timeline. CSL Behring is responsible for global regulatory submissions
and commercialization requirements for the Product. Certain clinical development and regulatory activities performed by
us are reimbursed by CSL Behring.

On the Signing Date, we and CSL Behring also entered into a development and commercial supply agreement,
pursuant to which, among other things, we will supply the Product to CSL Behring at an agreed-upon price commensurate
with  the  stand-alone  selling  price  (“SSP”).  We  will  be  responsible  to  supply  the  Product  until  such  time  that  these
capabilities may be transferred to CSL Behring or its designated contract manufacturing organization.

Other than under the CSL Behring Agreement, neither we nor CSL Behring may perform any clinical trials, with
the  exception  of  trials  required  to  extend  the  label  or  gain  marketing  authorization  outside  the  United  States  or  the
European Union, for any gene therapy product, gene-editing product, or any other product comprising an AAV vector to
conduct  nucleotide  transfer  (including  deoxyribonucleic  acid  (“DNA”)  and  ribonucleic  acid  (“RNA”))  for  the  treatment,
prevention, or cure of hemophilia B for a period commencing on June 24, 2020 and continuing for a period of four years
following  the  first  commercial  sale  of  the  Product  in  the  United  States,  and  neither  we  nor  CSL  Behring  may
commercialize  such  a  product  for  a  period  commencing  as  of  June  24,  2020  and  continuing  for  a  period  of  seven  years
following the first commercial sale of the Product in the United States. This exclusivity commitment would not bind an
acquirer of us that owns or controls such a product so long as certain precautions are followed to ensure that CSL Behring’s
confidential  information  and  our  proprietary  technology  related  to  the  Product  are  not  used  or  accessed  by  personnel  of
such acquirer who are developing or commercializing such competing product.

Unless earlier terminated as described below, the CSL Behring Agreement will continue on a country-by-country
basis until expiration of the royalty term in a country. The royalty term expires in a country on the later of (a) 15 years after
the  first  commercial  sale  of  the  Product  in  such  country,  (b)  expiration  of  regulatory  exclusivity  for  the  Product  in  such
country and (c) expiration of all valid claims of specific licensed patents covering the Product in such country. Either we or
CSL Behring may terminate the CSL Behring Agreement for the other party’s material breach if such breach is not cured
within a specified cure period. In addition, if CSL Behring fails to commercialize the Product in any of a group of major
countries  for  an  extended  period  of  time  following  the  first  regulatory  approval  of  the  Product  in  any  of  such  group  of
countries (other than due to certain specified reasons) and such failure has not been cured within a specified cure period,
then  we  may  terminate  the  CSL  Behring  Agreement.  CSL  Behring  may  also  terminate  the  CSL  Behring  Agreement  for
convenience.

The effectiveness of the transactions contemplated by the CSL Behring Agreement was contingent on completion
of review under antitrust laws in the United States, Australia, and the United Kingdom, and certain provisions of the CSL
Behring Agreement did not become effective until after we had received all such regulatory approvals and after the waiting
period under the HSR Act expired on May 5, 2021.

Table of Contents

Following  the  closing  of  the  CSL  Behring  Agreement,  we  recorded  $462.4  million,  including  a  $450.0  million
upfront  cash  payment,  as  license  revenue.  Upon  closing,  we  contractually  owed  to  our  licensors  $15.5  million  of  the
upfront payment received from CSL Behring.

We are eligible to receive more than $0.3 billion in regulatory, development, and first commercial sale milestones,
$1.3 billion in additional commercial milestones, and tiered double-digit royalties of up to a low-twenties percentage of net
product  sales  arising  from  the  collaboration.  As  of  December  31,  2021,  we  accrued  revenue  of  $55.0  million  related  to
milestone  payments  we  expect  to  receive  under  the  CSL  Behring  Agreement  following  the  submissions  of  a  Biological
License Application (“BLA”) to the U.S. Food and Drug Administration (“FDA”) and a Marketing Access Authorization
(“MAA”) to the European Medicines Agency (“EMA”), which are expected to be submitted during the first half of 2022.

Hemophilia B program – Etranacogene dezaparvovec (AMT-061)

Etranacogene dezaparvovec is our lead gene therapy candidate and includes an AAV serotype 5 (“AAV-5”) vector
incorporating  the  functional  human  Factor  IX  (“FIX”)  Padua  variant.  We  are  currently  conducting,  on  behalf  of  CSL
Behring, a pivotal Phase III study in 54 patients with severe and moderately-severe hemophilia B (“HOPE-B Study”). We
expect that a BLA is to be submitted to the FDA and MAA to the EMA in the first half of 2022.

The  FDA  has  agreed  that  etranacogene  dezaparvovec  will  fall  under  the  existing  Breakthrough  Therapy
Designation and IND for AMT-060 (our first-generation hemophilia B gene therapy), and the EMA has also agreed that
etranacogene dezaparvovec will fall under the PRIME designation.

On December 9, 2021, we announced the achievement of the pre-specified primary endpoint of non-inferiority in
annualized  bleeding  rate  (“ABR”)  18-months  following  administration  compared  to  baseline  Factor  IX  (“FIX”)
prophylactic  therapy  in  the  HOPE-B  Study.  ABR  for  all  bleeds  after  stable  FIX  expression,  assessed  at  18  months,  was
1.51 compared with the ABR of 4.19 for the lead-in period of at least six months, achieving the primary non-inferiority
endpoint and a secondary superiority endpoint (p=0.0002) in the HOPE-B Study. ABR for investigator-adjudicated FIX-
treated bleeds was 0.83 compared with lead-in ABR of 3.65 (p<0.0001). All participants continued to demonstrate durable,
sustained  increases  in  FIX  activity  at  18-months  post-infusion  with  a  mean  FIX  activity  of  36.9  percent  of  normal,  as
measured by a one-stage activated partial thromboplastin time-based (“aPTT-based”) clotting assay, compared to a mean
FIX activity of 39.0 percent of normal at 26-weeks of follow-up. Etranacogene dezaparvovec was generally well-tolerated
with over 80% of adverse events considered mild.

Huntington’s disease program (AMT-130)

AMT-130  is  our  novel  gene  therapy  candidate  for  the  treatment  of  Huntington’s  disease.  AMT-130  utilizes  our
proprietary, gene-silencing miQURE platform and incorporates an AAV vector carrying a miRNA specifically designed to
silence the huntingtin gene and the potentially highly toxic exon 1 protein fragment. We are currently conducting a Phase
I/II  clinical  trial  for  AMT-130  in  the  U.S.  and  a  Phase  Ib/II  study  in  the  EU.  Together,  these  studies  are  intended  to
establish safety, proof of concept, and the optimal dose of AMT-130 to take forward into Phase III development or into a
confirmatory study should an accelerated registration pathway be feasible. AMT-130 has received Orphan Drug and Fast
Track designations from the FDA and Orphan Medicinal Product Designation from the EMA.

On April 5, 2021, we announced the completion of enrollment of the low-dose cohort of the U.S. Phase I/II study
of AMT-130. The low- dose cohort includes 10 patients, of which six patients received treatment with AMT-130 and four
patients received imitation (“Sham”) surgery. The U.S. Phase I/II clinical trial is a randomized, controlled, double-blinded,
dose-escalation study of AMT-130.

On June 13, 2021, we announced the enrollment of the first two patients in the high-dose cohort of a U.S. Phase
I/II study. The high-dose cohort is planned to include 16 patients, of which 10 patients will receive treatment with AMT-
130  and  six  patients  will  receive  Sham  surgery.  The  initiation  of  patient  enrollment  in  the  high-dose  cohort  followed  a
meeting of the trial’s independent Data Safety Monitoring Board (“DSMB”) that reviewed safety data for the fully enrolled
first cohort of 10 patients.

Table of Contents

On December 16, 2021, we announced initial 12-month observations on the first four patients enrolled in the low-
dose cohort of the U.S. Phase I/II study. Two of the four enrolled patients received AMT-130, and two patients received
Sham surgery as a control. AMT-130 was generally well tolerated in the treated patients, with no serious adverse events
related  to  AMT-130.  Neurofilament  light  chain  (“NfL”),  a  biomarker  of  injury  in  the  brain,  increased  as  expected
immediately  following  the  surgical  procedure  and  returned  to  baseline  in  the  treated  patients.  NfL  remained  relatively
constant  in  the  two  untreated  control  patients.  Structural  magnetic  resonance  imaging  did  not  reveal  any  clinically
meaningful safety findings in either treated or control patients at one year of follow-up. Measurements of total and mutant
HTT protein in the cerebral spinal fluid of the four patients were highly variable and inconclusive. As of December 31,
2021, 19 patients have been enrolled in the clinical trial to date, including nine of 16 in the high-dose cohort.

Also on December 16, 2021, we announced the initiation of patient screening in our 15 patient, open-label, Phase
Ib/II study of AMT-130 in the EU, as well our plans to initiate a third cohort in the ongoing U.S. Phase I/II clinical trial.
The third cohort, which will include up to 18 additional randomized patients receiving the higher dose, will explore the use
of alternative stereotactic navigation systems to simplify placement of catheters for infusions of AMT-130.

Financing

As of December 31, 2020, a $35.0 million term loan was outstanding in accordance with the Second Amended
and  Restated  Loan  and  Security  Agreement  (the  “2018  Amended  Facility”)  between  us  and  Hercules  Capital,  Inc.
(“Hercules”).

On January 29, 2021, we and Hercules amended the 2018 Amended Facility (“2021 Amended Facility”). Pursuant
to  the  2021  Amended  Facility,  Hercules  agreed  to  an  additional  Facility  of  $100.0  million  (“Tranche  B”)  increasing  the
aggregate principal amount of the term loan facilities from $35.0 million to up to $135.0 million. On January 29, 2021, we
drew down $35.0 million of the Tranche B. Advances under Tranche B bore interest at a rate equal to the greater of (i)
8.25% or (ii) 8.25% plus the prime rate, less 3.25% per annum. The principal balance of $70.0 million and all accrued but
unpaid interest on advances under Tranche B was due on June 1, 2023. The back-end fee in respect of advances under the
2021 Amended Facility ranged from 1.65% to 6.85%, depending on the repayment date. In addition to Tranche B, the 2021
Amended  Facility  also  extended  the  interest  only  payment  period  of  the  previously  funded  $35.0  million  term  loan
(“Tranche A”) from January 1, 2022 to June l, 2023.

On  December  15,  2021,  we  and  Hercules  amended  and  restated  the  2021  Amended  Facility  (“2021  Restated
Facility”).  Pursuant  to  the  2021  Restated  Facility,  Tranche  A  and  Tranche  B  of  the  2021  Amended  Facility  with  a  total
 outstanding balance of $70.0 million were consolidated into one tranche with a total commitment of $100.0 million. We
drew down an additional $30.0 million, resulting in total principal outstanding as of December 31, 2021 of $100.0 million.
The 2021 Restated Facility extended the loan’s maturity date from June 1, 2023 until December 1, 2025. The interest-only
period is extended from January 1, 2023 to December 1, 2024, or December 1, 2025 if, prior to June 30, 2024, either (a) the
BLA for AMT-061 is approved by the FDA or (b) AMT-130 is advanced into a pivotal trial. The interest rate is adjustable
and is the greater of (i) 7.95% and (ii) 7.95% plus the prime rate less 3.25% per annum. Under the 2021 Restated Facility,
we  owe  a  back-end  fee  of  4.85%  of  the  outstanding  debt.  We  are  required  to  repay  the  facility  in  equal  monthly
installments of principal and interest between the end of the interest-only period and the maturity date. We continue to owe
a $2.5 million back-end fee related to the 2021 Amended Facility which is due on June 1, 2023.

On March 1, 2021, we entered into a Sales Agreement with SVB Leerink LLC (“SVB Leerink”) with respect to an
at-the-market  (“ATM”)  offering  program,  under  which  we  may,  from  time  to  time  in  our  sole  discretion,  offer  and  sell
through SVB Leerink, acting as agent, our ordinary shares, up to an aggregate offering price of $200.0 million. We pay
SVB Leerink a commission equal to 3% of the gross proceeds of the sales price of all ordinary shares sold through it as a
sales agent under the Sales Agreement.

In March and April of 2021, we issued 921,730 ordinary shares at a weighted average price of $33.52 per ordinary

share, with net proceeds of $29.6 million, after deducting underwriting discounts and net of offering expenses.

Intellectual Property

On May 11, 2021, Pfizer, Inc. filed three petitions at the USPTO seeking Inter Partes Review of U.S. Patent Nos.
9,982,248  (the  “‘248  Patent”)  and  10,465,180  (the  “‘180  Patent”  and  together  with  the  ‘248  Patent,  the  “Patents”).  The
petitions collectively seek to invalidate all claims of the Patents. In August 2021, we filed our responses asking the USPTO
to deny institution of the IPR proceedings. On November 17, 2021, the PTAB issued decisions granting institution on all
three IPR proceedings. Our response to the petition is currently due to be filed on March 3, 2022.

Our Mission and Strategy

Our mission is to deliver curative, one-time administered genomic medicines that transform the lives of patients.
We  aim  to  build  an  industry-leading,  fully  integrated,  and  global  company  that  leverages  its  technology  and  proprietary
manufacturing platform to deliver these medicines to patients with serious unmet medical needs.

Our strategy to achieve this mission is to:

In  collaboration  with  our  partner,  achieve  regulatory  approvals  and  the  commercial  launch  of  etranacogene
dezaparvovec (AMT-061). Etranacogene dezaparvovec is a one-time administered gene therapy that combines the potential
advantages of AAV5 with an enhanced Padua-FIX transgene, and may provide clinical and tolerability benefits to nearly all
patients with hemophilia B. In June 2020, we entered into a commercialization and license agreement with CSL Behring
pursuant to which CSL Behring received exclusive global rights to etranacogene dezaparvovec. We are responsible for the
manufacturing of etranacogene dezaparvovec and CSL Behring is responsible for the development and commercialization
of  the  Product.  In  September  2021,  we  completed  the  last  patient’s  78-week  follow-up  visit  in  the  HOPE-B  Phase  III
pivotal study, which enrolled a total of 54 patients.

Advance  the  development  of  AMT-130,  a  potential  one-time  gene-therapy  approach  for  the  treatment  of
Huntington’s  disease.  AMT-130  is  the  first  AAV-based  gene  therapy  to  enter  clinical  development  for  Huntington’s
disease. It consists of an AAV5 vector carrying an artificial micro-RNA specifically tailored to silence the huntingtin gene
and  leverages  our  proprietary  miQURE™  silencing  technology.  The  therapeutic  goal  of  AMT-130  is  to  inhibit  the
production of the mutant protein (mHTT). Patient enrollment is ongoing in two clinical trials of AMT-130 being conducted
in the U.S. and Europe.

 Build a pipeline of gene therapy programs focused on rare, liver-directed and central-nervous system (“CNS”)
diseases.  Beyond  our  lead  clinical  program  in  Huntington’s  disease  and  our  late-stage  program  in  hemophilia  B  now
partnered  with  CSL  Behring,  we  have  a  pipeline  of  additional  AAV-based  gene  therapy  programs  in  various  stages  of
preclinical  development  focused  on  larger  market  opportunities  and  built  on  validated  targets  and  technologies.  We  are
leveraging novel vectors, promoters, and manufacturing capabilities, to develop gene therapies that have the potential to be
best  or  first  in  class  and  are  primarily  focused  on  rare,  monogenic  liver-directed,  and  CNS  disorders  as  well  as
cardiovascular and muscle diseases.

Maintain  our  leadership  position  in  commercial-scale  AAV  manufacturing.  We  have  established  cGMP,
commercial-scale  manufacturing  capabilities  for  AAV-based  gene 
in  our  state-of-the-art  Lexington,
Massachusetts  facility  and  begun  construction  of  a  second  cGMP  manufacturing  facility  in  our  Amsterdam,  the
Netherlands  facility  that  will  complement  our  work  in  Lexington.  We  seek  to  establish  larger  scale  and  highly  cost-
effective capabilities to address more prevalent disorders, and we believe the modularity of our platform provides us with
distinct advantages, including the potential for reduced development risk and faster times to market.

therapies 

Leverage the favorable immunogenicity profile of AAV5-based gene therapies to develop multiple products. We
have developed extensive experience with our AAV5-based gene therapies, including in five clinical trials in multiple liver-
directed and CNS diseases. During these clinical trials, no patient treated with AAV5-based gene therapies experienced a
confirmed  immune  response  to  the  AAV5  capsid  or  complications  associated  with  T-cell  activation.  Additionally,  the
AAV5  capsid  has  demonstrated  a  low  avidity  to  pre-existing  neutralizing  antibodies  (“Nab”),  which  may  enable  all,  or
nearly all patients to be eligible for treatment with AAV5-based gene therapies. We are now in the process of developing
Smart AAV capsids that combine the advantages of AAV5 with antibody-directed delivery to move cargo across the blood
brain barrier and to improve transduction of cells in the CNS.

Invest  in  next-generation  technologies  with  the  goal  of  enhancing  safety,  improving  efficacy,  and  expanding
the  applicability  of  gene  therapy  to  patients.  We  are  developing  proprietary  technologies  that  have  the  potential  to
augment the safety and efficacy of our product candidates and broaden the applicability of our gene therapies to a wider
range of diseases and patients. These technologies include (i) miQURE, our one-time administered gene silencing platform,
(ii) goQURE for simultaneous silencing of a disease gene and replacement with a healthy gene, (iii) AbQURE, using the
power of AAV5 to deliver therapeutic antibodies systemically from the liver or into the CNS from cells in the brain, (iv)
QUREDose  for  dosing  through  neutralizing  antibodies  and  re-dosing  technology;  along  with  other  tailored  vectors,
promoters,  and  novel  transgenes.  These  technologies  are  developed  both  in-house  by  our  experienced  research  team  in
Amsterdam, the Netherlands, as well as via collaborations with third parties.

Continue  to  expand  our  intellectual  property  portfolio.  We  have  established  what  we  believe  is  a  leading
intellectual property portfolio covering various aspects of our technology and programs, including (i) elements of our gene
therapy  constructs,  such  as  AAV  vectors,  promoters  and  transgenes  (ii)  innovative  delivery  technologies,  such  as  re-
administration  of  AAV  gene  therapy;  and  (iii)  proprietary  manufacturing  processes  covering  key  components  of  our
upstream and downstream capabilities. We expect to continue to expand our intellectual property portfolio by aggressively
seeking patent protection for promising aspects of our technology platform and product candidates.

Liver-directed diseases

Hemophilia B (etranacogene dezaparvovec)

Hemophilia B Disease and Market Background

Hemophilia  B  is  a  serious  and  rare  inherited  disease  in  males  characterized  by  insufficient  blood  clotting.  The
condition  can  lead  to  repeated  and  sometimes  life-threatening  episodes  of  external  and  internal  bleeding  following
accidental trauma or medical interventions. Severe hemophilia is characterized by recurrent episodes of spontaneous joint
bleeds that cause long-term damage to the joints resulting in disabling arthropathy. Bleeds may be fatal if they occur in the
brain. The deficient blood clotting results from the lack of functional human Factor IX (“hFIX”). Treatment of hemophilia
B  today  consists  of  prophylactic  or  on-demand  protein  replacement  therapy,  in  which  one  to  three  times  weekly
intravenous  administrations  of  plasma-derived  or  recombinant  hFIX  are  required  to  prevent  bleeding  and  once  daily
infusions in case bleeding occurs. Hemophilia B occurs in approximately 1 out of 30,000 live male births.

CSL Behring collaboration

On  June  24,  2020,  we  entered  into  the  CSL  Behring  Agreement  pursuant  to  which  CSL  Behring  received
exclusive  global  rights  to  etranacogene  dezaparvovec.  The  transaction  became  fully  effective  on  May  6,  2021,  one  day
after the waiting period under the HSR Act expired on May 5, 2021.

CSL Behring is responsible for the development and commercialization of the Product. We agreed to complete the

validation of the current manufacturing process as well as to the development and, if requested by CSL Behring, the
validation of a next generation manufacturing process. We will be entitled to receive a development milestone payment if
we complete these activities in accordance with an agreed development plan and timeline. CSL Behring is responsible for
global regulatory submissions and commercialization requirements for the Product. Certain clinical development and
regulatory activities performed by us are reimbursed by CSL Behring.

On the Signing Date, we and CSL Behring also entered into a development and commercial supply agreement,
pursuant to which, among other things, we will supply the Product to CSL Behring at an agreed-upon price commensurate
with the SSP. We will be responsible to supply the Product until such time that these capabilities may be transferred to CSL
Behring or its designated contract manufacturing organization.

Development of etranacogene dezaparvovec for Hemophilia B

We believe we have substantially completed the development of etranacogene dezaparvovec, a gene therapy for
patients  with  hemophilia  B  that  is  designed  to  restore  FIX  activity,  an  essential  protein  for  blood  clotting.  Etranacogene
dezaparvovec includes an AAV5 vector incorporating the FIX-Padua variant (“FIX-Padua”).

Etranacogene  dezaparvovec 

is 

intended 

to  be  delivered  by 

intravenous 

(“IV”)-infusion,  without

immunosuppressant therapy, through the peripheral vein in a single treatment session for approximately 30 minutes.

Our goal for etranacogene dezaparvovec was to develop a gene therapy with the following profile:

-
-
-
-

long-term safety, including a favorable immunogenicity profile;
predictable, sustained and potentially curative increases in FIX activity;
significant reductions in both bleeding rates and the need for FIX replacement therapy; and
broad patient eligibility, including the potential to treat all or nearly all patients with hemophilia B.

AAV5-based gene therapies have been used in a multitude of clinical trials, including five clinical trials conducted
by  us  in  patients  with  hemophilia  B  and  other  disorders.  No  patient  treated  in  clinical  trials  with  our  AAV5-based  gene
therapies  has  experienced  any  confirmed,  cytotoxic  T-cell-mediated  immune  response  to  the  capsid.  An  independent
clinical  trial  has  demonstrated  that  AAV5  has  the  lowest  prevalence  of  pre-existing  neutralizing  antibodies  compared  to
other AAV vectors. Data from our clinical, preclinical, and nonclinical studies suggest that all, or nearly all patients may be
eligible for treatment with etranacogene dezaparvovec.

In  June  2018,  we  initiated  our  Phase  III  HOPE-B  pivotal  trial  of  etranacogene  dezaparvovec.  The  trial  is  a
multinational, multi-center, open-label, single-arm study to evaluate the safety and efficacy of etranacogene dezaparvovec.

In March 2020, we completed dosing of the 54 patients in the HOPE-B trial. The targeted number of patients to be
dosed per the clinical trial protocol was 50. The adult hemophilia B patients, who were classified as severe or moderately
severe,  were  enrolled  in  a  six-month  observational  period  prior  to  dosing  during  which  time  they  continued  to  use  their
current standard of care to establish a baseline control. After the six-month lead-in period, patients received a single IV-
administration of etranacogene dezaparvovec. Patients enrolled in the HOPE-B trial were tested for the presence of pre-
existing  neutralizing  antibodies  to  AAV5  but  not  excluded  from  the  trial  based  on  their  titers.  Following  a  pre-BLA
submission meeting with the FDA on June 4, 2021 the primary endpoint was set as a non-inferiority analysis in ABR 18-
months  following  administration  compared  to  baseline  FIX  prophylactic  therapy  in  the  pivotal  Phase  III  HOPE-B  gene
therapy trial (approximately 52-weeks after steady-state is achieved). In September 2021, we completed the last patient’s
18-months follow-up visit which enrolled a total of 54 patients.

Table of Contents

On December 9, 2021, we announced the achievement of the pre-specified primary endpoint of non-inferiority in
ABR 18-months following administration compared to baseline FIX prophylactic therapy in the HOPE-B Study. ABR for
all  bleeds  after  stable  FIX  expression,  assessed  at  18  months,  was  1.51  compared  with  the  ABR  of  4.19  for  the  lead-in
period  of  at  least  six  months,  achieving  the  primary  non-inferiority  endpoint  and  a  secondary  superiority  endpoint
(p=0.0002)  in  the  HOPE-B  Study.  ABR  for  investigator-adjudicated  FIX-treated  bleeds  was  0.83  compared  with  lead-in
ABR  of  3.65  (p<0.0001).  All  participants  continued  to  demonstrate  durable,  sustained  increases  in  FIX  activity  at  18-
months post-infusion with a mean FIX activity of 36.9 percent of normal, as measured by a one-stage aPTT-based clotting
assay, compared to a mean FIX activity of 39.0 percent of normal at 26-weeks of follow-up. Etranacogene dezaparvovec
was generally well-tolerated with over 80% of adverse events considered mild.

 We expect that a BLA is to be submitted to the FDA and a MAA to the EMA in the first half of 2022.

In  September  2018,  we  completed  the  dosing  of  a  Phase  IIb  dose-confirmation  study  of  etranacogene
dezaparvovec.  The  Phase  IIb  study  is  an  open-label,  single-dose,  single-arm,  multi-center  trial  being  conducted  in  the
United  States.  The  objective  of  the  study  was  to  evaluate  the  safety  and  tolerability  of  etranacogene  dezaparvovec  and
confirm  the  dose  based  on  FIX  activity  at  six  weeks  after  administration.  Three  patients  with  severe  hemophilia  were
enrolled in this study and received a single intravenous infusion of 2x1013 genome copies per kilogram (“gc/kg”). Patients
were evaluated for the presence of pre-existing neutralizing antibodies to AAV5 but were not excluded from the trial on
this basis. We have followed the patients for more than two years to assess FIX activity, bleeding rates and usage of FIX
replacement  therapy,  and  will  monitor  the  three  patients  for  a  total  of  five  years  to  evaluate  the  safety  of  etranacogene
dezaparvovec.

In  December  2018,  the  study’s  Data  Monitoring  Committee  evaluated  initial  data  from  the  Phase  IIb  study  and

confirmed the dose of 2x1013 gc/kg for the Phase III pivotal trial.

In February, May, July, and December 2019, and in December 2020, we presented updated data from the Phase
IIb  dose-confirmation  study  of  etranacogene  dezaparvovec.  The  most  recent  data  that  we  announced  in  December  2020
from the Phase IIb study of etranacogene dezaparvovec showed that all three patients experienced increasing and sustained
FIX  levels  after  a  one-time  administration  of  etranacogene  dezaparvovec.  Mean  FIX  activity  was  44.2%  of  normal  two
years after administration, exceeding threshold FIX levels generally considered sufficient to significantly reduce the risk of
bleeding events. The first patient achieved FIX activity of 44.7% of normal, the second patient was 51.6% of normal and
the third patient was 36.3% of normal. The second and third patients had previously screen-failed and were excluded from
another gene therapy study due to pre-existing neutralizing antibodies to a different AAV vector. At two years after dosing,
two of the three participants remain free from bleeds and use of FIX replacement therapy. A single bleed has been reported
in  one  participant,  who  has  used  a  total  of  two  FIX  infusions  (excluding  surgery).  All  patients  have  remained  free  of
prophylaxis in the two years since receiving etranacogene dezaparvovec.

The  FDA  has  agreed  that  etranacogene  dezaparvovec  will  fall  under  the  existing  Breakthrough  Therapy
Designation and IND for AMT-060 (our first-generation hemophilia B gene therapy), and the EMA has also agreed that
etranacogene dezaparvovec will fall under the PRIME designation.

Intellectual Property for etranacogene dezaparvovec

In 2017, we acquired intellectual property from Professor Paolo Simioni (“Dr. Simioni”), a hemophilia expert at
the University of Padua, Italy. The intellectual property includes U.S. Patent Number 9,249,405, (the “‘405 Patent”). The
‘405 Patent was subject to Inter Partes Review (“IPR”) proceedings at the Patent Trials and Appeal Board (“PTAB”) of the
USPTO. Ultimately, the challenged claims of the ‘405 Patent were withdrawn but the unchanged claims remain in force.
The ‘405 Patent thus covers compositions of FIX-Padua polypeptides (proteins), their therapeutic uses as well as nucleic
acid sequences encoding FIX-Padua. The FIX Padua variant is a FIX protein carrying a leucine at the R338 position, often
called the “FIX-Padua” or “Padua mutant”.

On May 29, 2018, the USPTO granted us a second patent, U.S. Patent Number 9,982,248, which covers methods
of treating coagulopathies (bleeding disorders), including hemophilia B, using AAV-based gene therapy with nucleic acid
encoding the hyperactive FIX Padua variant. 

On November 5, 2019, the USPTO granted us a third patent, U.S. Patent Number 10,465,180, which covers any
AAV  comprising  a  nucleic  acid  encoding  a  FIX-Padua  protein,  and  promoter  sequences,  transcription  termination  and
control elements. The claims also cover FIX-Padua variants with at least 70% sequence identity to FIX-R338L.

Table of Contents

In addition to the U.S. patents, on February 20, 2018, the Canadian Intellectual Property Office granted Patent
Number 2,737,094, which covers FIX-Padua nucleic acids for use in gene therapy and FIX-Padua polypeptides for use in
FIX replacement therapy.

In  Europe,  European  Patent  2337849  directed  to  a  FIX  polypeptide  protein  was  withdrawn  during  opposition
proceedings  with  the  European  Patent  Office  (“EPO”).  In  addition,  EP  3252157,  a  refused  divisional  European  patent
application was withdrawn. We are still pursuing a European divisional patent application that was filed on May 14, 2019.
Both in the U.S. and in Europe, we have pending divisional applications still in prosecution phases.

On May 11, 2021, Pfizer, Inc. filed three petitions at the USPTO seeking Inter Partes Review of U.S. Patent Nos.
9,982,248  (the  “‘248  Patent”)  and  10,465,180  (the  “‘180  Patent”  and  together  with  the  ‘248  Patent,  the  “Patents”).  The
petitions collectively seek to invalidate all claims of the Patents. In August 2021, we filed our responses asking the USPTO
to deny institution of the IPR proceedings. On November 17, 2021, the PTAB issued decisions granting institution on all
three IPR proceedings. Our response to the petition is currently due to be filed on March 3, 2022.

Fabry disease program (AMT-191)

Fabry Disease and Market Background

Fabry  disease  is  a  progressive,  inherited,  multisystemic  lysosomal  storage  disease  characterized  by  specific
neurological,  cutaneous,  renal,  cardiovascular,  cochleo-vestibular,  and  cerebrovascular  manifestations.  Fabry  disease  is
caused by a defect in a gene that encodes for a protein called α-galactosidase A (“GLA”). The GLA protein is an essential
enzyme  required  to  breakdown  globotriaosylsphingosine  (“Gb3”)  and  lyso-globotriaosylsphingosine  (“lyso-Gb3”).  In
patients living with Fabry disease, Gb3 and lyso-Gb3 accumulate in various cells throughout the body causing progressive
clinical  signs  and  symptoms  of  the  disease.  Current  treatment  options,  which  consist  of  bi-weekly  intravenous  enzyme
replacement therapy, typically have no therapeutic benefit in patients with advanced renal or cardiac disease. Studies have
also shown that a majority of male patients develop antibodies that inhibit the GLA protein and interfere with therapeutic
efficacy.

Fabry disease has two major disease phenotypes: the type 1 “classic” and type 2 “later-onset” subtypes. Both lead
to  renal  failure,  and/or  cardiac  disease,  and  early  death.  Type  1  males  have  little  or  no  functional  a-Gal  A  enzymatic
activity  (<1%  of  normal  mean)  and  marked  accumulation  of  GL-3/Gb3  and  related  glycolipids  in  capillaries  and  small
blood  vessels  which  cause  the  major  symptoms  in  childhood  or  adolescence.  In  contrast,  males  with  the  type  2  “later-
onset” phenotype (previously called cardiac or renal variants) have residual a-Gal A activity, lack GL-3/Gb3 accumulation
in capillaries and small blood vessels, and do not manifest the early manifestations of type 1 males. They experience an
essentially  normal  childhood  and  adolescence.  They  typically  present  with  renal  and/or  cardiac  disease  in  the  third  to
seventh decades of life. Most type 2 later-onset patients have been identified by enzyme screening of patients in cardiac,
hemodialysis, renal transplant, and stroke clinics and recently by newborn screening. Fabry disease occurs in all racial and
ethnic populations and affects males and females. It is estimated that type 1 classic Fabry disease affects approximately one
in 40,000 males. The type 2 later-onset phenotype is more frequent, and in some populations may occur as frequently as
about 1 in 1,500 to 4,000 males.

Our Development of AMT-191 for Fabry Disease

In September 2020, we selected a lead gene therapy candidate (AMT-191) for the treatment of Fabry disease to
advance  into  Investigational  New  Drug-enabling  studies  (“IND-enabling  studies”).  The  lead  candidate  is  a  one-time
administered  AAV5  gene  therapy  incorporating  the  GLA  transgene.  In  preclinical  studies  comparing  multiple  product
candidates, including constructs incorporating a modified alpha-N-acetylgalactosaminidase transgene (modNAGA), AMT-
191 demonstrated the most robust and sustained increases in GLA activity.

In October 2021, we presented preclinical data for AMT-191 at the European Society of Gene and Cell Therapy
(“ESGCT”), confirming efficiency and cross correction in a Fabry mouse model, with increased gamma-linolenic acid in
the liver, kidney, heart, and brain and normalized lysoglobotriaosylceramide-3 levels in main target organs.

Central Nervous System diseases

Huntington’s Disease

Huntington’s Disease and Market Background

Huntington’s  disease  is  a  severe  genetic  neurodegenerative  disorder  causing  loss  of  muscle  coordination,
behavioral abnormalities, and cognitive decline, often resulting in complete physical and mental deterioration over a 12 to
15-year  period.  The  median  survival  time  after  onset  is  15  to  18  years  (range:  5  to  >25  years).  Huntington’s  disease  is
caused  by  an  inherited  defect  in  a  single  gene  that  codes  for  a  protein  called  Huntingtin  (“HTT”).  The  prevalence  of
Huntington’s disease is three to seven per 100,000 in the general population, similar in men and women, and it is therefore
considered a rare disease. Despite the ability to identify Huntington’s disease mutation carriers decades before onset, there
is  currently  no  available  therapy  that  can  delay  onset  or  slow  progression  of  the  disease.  Although  some  symptomatic
treatments are available, they only are transiently effective despite significant side effects.

Our Development of AMT-130 for Huntington’s Disease

AMT-130  is  our  novel  gene  therapy  candidate  for  the  treatment  of  Huntington’s  disease.  AMT-130  utilizes  our
proprietary, gene-silencing miQURE platform and incorporates an AAV vector carrying a miRNA specifically designed to
silence the huntingtin gene and the potentially highly toxic exon 1 protein fragment. We are currently conducting a Phase
I/II  clinical  trial  for  AMT-130  in  the  U.S.  and  a  Phase  Ib/II  study  in  the  EU.  Together,  these  studies  are  intended  to
establish safety, proof of concept, and the optimal dose of AMT-130 to take forward into Phase III development or into a
confirmatory study should an accelerated registration pathway be feasible. AMT-130 has received Orphan Drug and Fast
Track designations from the FDA and Orphan Medicinal Product Designation from the EMA.

Our goal for AMT-130 is to develop a gene therapy with the following profile:

(1) One-time  administration  of  disease-modifying  therapy  into  the  striatum,  the  area  of  the  brain  where

Huntington’s disease is known to manifest;

(2) Biodistribution of the therapy in both the deep and cortical structures of the brain via transport of the AAV

vector and through secondary exosome-mediated delivery; and
(3) Safe, on-target and durable knockdown of HTT and exon 1 HTT.

In January 2019, our IND application for AMT-130 was cleared by the FDA.

In February 2019, we presented new preclinical data at the 14th Annual CHDI Huntington’s disease Therapeutics
Conference  that  illustrate  the  therapeutic  potential  of  AMT-130  in  restoring  function  of  damaged  brain  cells  in
Huntington’s disease. In that study, AMT-130 was generally well-tolerated and resulted in a sustained reduction of mutant
huntingtin protein.

On April 5, 2021, we announced the completion of enrollment of the low-dose cohort of the U.S. Phase I/II study
of AMT-130. The low-dose cohort includes 10 patients, of which six patients received treatment with AMT-130 and four
patients  received  Sham  surgery.  The  U.S.  Phase  I/II  clinical  trial  is  a  randomized,  controlled,  double-blinded,  dose-
escalation study of AMT-130.

On June 13, 2021, we announced the enrollment of the first two patients in the high-dose cohort of a U.S. Phase
I/II study. The high-dose cohort is planned to include 16 patients, of which 10 patients will receive treatment with AMT-
130  and  six  patients  will  receive  Sham  surgery.  The  initiation  of  patient  enrollment  in  the  high-dose  cohort  followed  a
meeting of the trial’s independent DSMB that reviewed safety data for the fully enrolled first cohort of 10 patients.

Table of Contents

On December 16, 2021, we announced initial 12-month observations on the first four patients enrolled in the low-
dose cohort of the U.S. Phase I/II study. Two of the four enrolled patients received AMT-130, and two patients received
Sham surgery as a control. AMT-130 was generally well tolerated in the treated patients, with no serious adverse events
related  to  AMT-130.  NfL,  a  biomarker  of  injury  in  the  brain,  increased  as  expected  immediately  following  the  surgical
procedure  and  returned  to  baseline  in  the  treated  patients.  NfL  remained  relatively  constant  in  the  two  untreated  control
patients. Structural magnetic resonance imaging did not reveal any clinically meaningful safety findings in either treated or
control patients at one year of follow-up. Measurements of total and mutant HTT protein in the cerebral spinal fluid of the
four  patients  were  highly  variable  and  inconclusive.  As  of  December  31,  2021,  19  patients  have  been  enrolled  in  the
clinical trial to date, including nine of 16 in the high-dose cohort.

Also on December 16, 2021, we announced the initiation of patient screening in our 15 patient, open-label, Phase
Ib/II study of AMT-130 in the EU, as well our plans to initiate a third cohort in the ongoing U.S. Phase I/II clinical trial.
The third cohort, which will include up to 18 additional randomized patients receiving the higher dose, will explore the use
of alternative stereotactic navigation systems to simplify placement of catheters for infusions of AMT-130.

Temporal Lobe Epilepsy Program (AMT-260)

Temporal Lobe Epilepsy Disease and Market Background

TLE affects approximately 1.3 million people in the U.S. and Europe alone, of which approximately 0.8 million
patients  are  unable  to  adequately  control  acute  seizures  with  currently  approved  anti-epileptic  therapies.  Patients  with
refractory TLE experience increased morbidity, excess mortality, and poor quality of life.

Our Development of AMT-260 for Temporal Lobe Epilepsy

AMT-260  is  being  developed  based  on  exclusive  licenses  to  certain  patents  obtained  in  2020  from  two  French

research institutions that continue to collaborate with us.

AMT-260  is  a  gene  therapy  using  an  AAV9  vector.  The  use  of  AAV9  to  deliver  any  sequence  that  affects  the
expression of the GRIK 2 gene sequence in humans has been exclusively licensed from Regenxbio. Regenxbio provides
contractually  agreed  research  and  development  services  up  to  the  transfer  of  manufacturing  activities  to  a  designated
contract manufacturer.

AMT-260, employs miRNA silencing technology to target suppression of aberrantly expressed kainate receptors

in the hippocampus of patients with TLE.

In October 2021, we presented preclinical data for AMT-260 at the ESGCT. AMT-260 reduces the expression of
GluK2 in cortical neurons, reduces epileptiform activity and hyperlocomotion in a preclinical model of epilepsy and blocks
epileptiform discharges in organotypic slices from patients with TLE.

Parkinson’s Disease (AMT-210)

AMT-210 is our preclinical product candidate for the treatment of Parkinson’s disease, targeting alpha-synuclein

as a potential treatment for Parkinson’s disease.

Parkinson’s disease is a progressive neurodegenerative disorder that leads to motor deterioration and debilitating
non-motor symptoms. It is the second most common neurodegenerative disorder after Alzheimer’s disease, and no disease-
modifying therapies are available.

Parkinson’s disease is believed to be caused through the presence of toxic alpha-synuclein aggregates, affecting
dopaminergic circuits. AMT-210 is a one-time, brain-targeting AAV gene therapy incorporating uniQure’s miQURE gene
silencing  technology.  It  is  designed  to  halt  misfolded  alpha-synuclein  and  subsequent  fibril  formation  in  familial  and
sporadic Parkinson’s disease patients.

Alzheimer’s Disease (AMT-240)

AMT-240 

is  our  preclinical  product  candidate  for 

treatment  autosomal  dominant  Alzheimer’s
disease. Alzheimer’s  disease  is  the  most  prevalent  neurodegenerative  disease,  causing  dementia  and  subsequent  gradual
loss  of  ability  to  function  with  disease  progression. Apolipoprotein  E  (APOE)  is  believed  to  potentially  be  an  important
factor in the pathogenesis of Alzheimer’s disease. APOE consists of 3 major isoforms that are structurally and functionally
different. The APOE4 isoform is believed to potentially be the largest risk factor to develop Alzheimer’s. In contrast to the
toxic properties of APOE4, clinical case studies indicate a potentially protective role of other APOE variants.

the 

AMT-240  is  a  one-time  gene  therapy  using  uniQure's  miQURE  gene-silencing  technology  to  silence  the  toxic
APOE  variant,  in  combination  with  overexpressing  a  protective  APOE  variant  as  treatment  for  autosomal  dominant
Alzheimer’s disease patients.

Amyotrophic Lateral Sclerosis (AMT-160)

AMT-161  is  our  preclinical  product  candidate  utilizing  our  miQURE  gene  silencing  technology  to  target  toxic

C9ORF72 as a potential treatment for amyotrophic lateral sclerosis (ALS). 

ALS is caused by degeneration of upper and lower motor neurons, resulting in muscle weakness and atrophy. This
rapid progressive loss of motor neurons typically starts at mid-life and median survival from disease manifestation is no
more than two to four years.

The most prevalent genetic defect causing ALS is a G4C2 hexanucleotide repeat expansion in the C9ORF72 gene,
which acquires toxic properties resulting in degeneration starting in motor neurons in the spinal cord. AMT-161 is designed
to be a one-time, intrathecally-administered AAV gene therapy using the miQURE silencing technology to target repeat-
expanded C9ORF72 to lower toxic RNA aggregates and prevent dipeptide protein formation. 

Spinocerebellar Ataxia, Type 3 (AMT-150)

After conducting a comprehensive review of our product candidates, we decided in December 2021 to deprioritize

the preclinical development of AMT-150, shifting resources and focus to our other research programs.

BMS Partnered Research Programs

We and Bristol-Myers Squibb (“BMS”) entered into a collaboration and license agreement in May 2015 (“BMS
CLA”).  The  BMS  CLA  provides  BMS  with  exclusive  access  to  our  gene  therapy  technology  platform  for  four  targets
primarily in cardiovascular diseases.

New Technology Development

We are seeking to develop next-generation technologies with the goal of further improving the potential of AAV-

based gene therapies to treat patients suffering from debilitating diseases.

We  are  focused  on  innovative  technologies  across  each  of  the  key  components  of  an  AAV-based  gene  therapy,
including:  (i)  the  capsid,  or  the  outer  viral  protein  shell  that  encloses  the  target  DNA;  (ii)  the  promoter,  or  the  DNA
sequence that drives the expression of the transgene; and (iii) the transgene, or therapeutic gene.

We  dedicate  significant  effort  to  designing  and  screening  novel  AAV  capsids  with  the  potential  for  (i)  higher
biological potency; (ii) improved biodistribution including greater cell transduction and increased cellular specificity; and
(iii)  enhanced  safety.  We  believe  we  have  significant  expertise  in  vector  engineering  and  have  created  promising
genetically engineered capsids using a “rational design” approach.

We  are  focusing  our  efforts  on  rationally  engineering  the  AAV  capsids  to  target  them  to  specific  cells  and/or
tissues. These engineered viruses contain antibody fragments or peptides that target them to specific tissues or cells and to
diminish potential off target effects.

18

Table of Contents

We  work  extensively  on  designing  synthetic  promoters  with  the  potential  of  enabling  higher  levels  of  protein
expression  in  specific  tissue  types.  A  “promoter”  is  an  essential  component  of  a  gene  therapy  construct  that  controls
expression of a therapeutic protein. Synthetic promoters, that do not exist in nature, are optimally tailored to drive gene
expression at a desired level and specificity.

To  further  tailor  and  optimize  gene  therapies  to  address  certain  disorders  we  may  also  incorporate  specific
modifications into the transgenes of our gene therapy constructs. For example, we incorporated the Padua-FIX variant into
our  hemophilia  B  gene  therapy  to  substantially  increase  the  resulting  FIX  activity  and  potentially  improve  clinical
outcomes.  For  other  programs,  such  as  our  gene  therapy  construct  for  Fabry  disease,  we  have  also  utilized  modified
transgenes with the goal of enhancing efficacy, durability, and safety, as well as expanding the access of gene therapies to
patients with inhibitors.

We are developing methods for delivering multiple doses of a gene therapy to a patient using a combination of
immune  modulation  and  antibody  neutralization.  The  ability  to  deliver  multiple  doses  of  an  AAV  to  a  patient  could
potentially increase our ability to deliver the correct dose of a virus to a patient and might enable us to re-administer our
gene therapies to patients that have lost expression of a transgene.

We have also demonstrated the ability to deliver engineered DNA constructs that can silence or suppress disease-
causing genes. Our miQURE gene silencing platform, based on exclusively licensed technology from Cold Spring Harbor
Laboratory (“CSHL”), is designed to degrade mutated genes without off-target toxicity and induce silencing of the mutated
gene  in  the  entire  target  organ  through  secondary  exosome-mediated  delivery.  miQURE-based  gene  therapy  candidates,
such as AMT-130, incorporate proprietary, therapeutic miRNA constructs that can be delivered using AAVs to potentially
provide  long-lasting  activity.  Preclinical  studies  of  miQURE-based  gene  therapies  have  demonstrated  several  important
advantages,  including  enhanced  tissue-specificity,  improved  nuclear  and  cytoplasmic  gene  lowering  and  no  off-target
effects associated with impact to the cellular miRNA or messenger RNA transcriptome.

Commercial-Scale Manufacturing Capabilities

The ability to reliably produce at a high quality and at commercial scale is a critical success factor in AAV gene
therapy.  We  produce  our  gene  therapies  at  our  state-of-the-art,  Lexington,  Massachusetts-based  manufacturing  facility
using a proprietary baculovirus expression vector system.

We believe our integrated manufacturing capabilities provide us several potential advantages, including:

(1) Know-how. Since our founding in 1998, we have invested heavily in developing optimized processes and methods
to  reliably  and  reproducibly  manufacture  AAV-based  gene  therapies  at  commercial  scale.  During  this  time,  we
have  accumulated  significant  internal  experience  and  knowledge  of  the  underlying  production  technology  and
critical  quality  attributes  of  our  products.  These  learnings  have  been  essential  in  developing  a  modular,  third
generation production system that can be used to produce all our gene therapy products.

(2) Flexibility.  Controlling  cGMP  manufacturing  allows  us  to  rapidly  adapt  our  production  schedule  to  meet  the
needs of our business. By controlling our manufacturing, we do not rely on contract manufacturers, nor do we
require costly and time-consuming technology transfers to third parties. Our facility is designed to commercially
supply multiple products and are flexibly designed to accommodate expansion and scale up as our needs change.

(3) Faster Path to Market. We believe our manufacturing platform enables us to rapidly produce new products for
clinical  investigation,  minimize  time  between  clinical  phases  and  complete  scale-up  as  product  candidates
advance  into  late-stage  development  and  commercialization.  For  example,  in  transitioning  our  hemophilia  B
program  from  AMT-060  to  AMT-061,  we  were  able  to  rapidly  demonstrate  manufacturing  comparability  and
produce clinical material for our ongoing Phase III pivotal study.

(4) High Purity. The baculovirus system eliminates the risk of introducing mammalian cell derived impurities.

(5) Scalability. We have demonstrated our manufacturing process is reproducible at volumes ranging from 2 liters to
500 liters and believe it is possible to achieve higher scale production with our insect-cell, baculovirus system.

19

Table of Contents

(6) Low Cost of Goods. We believe our ability to scale production has the potential to significantly reduce unit costs.
Our  manufacturing  process  also  utilizes  fully  disposable  components,  which  enables  faster  change-over  times
between batches and lower costs associated with cleaning and sterilization. Additionally, our production system
does not require the use of plasmids, which can be a costly raw material.

Intellectual Property

Introduction

We strive to protect the proprietary technologies that we believe are important to our business, including seeking
and maintaining patent protection in the United States, Europe, and other countries for novel components of gene therapies,
the chemistries, and processes for manufacturing these gene therapies, the use of these components in gene therapies, our
technology  platform,  and  other  inventions  and  related  technology.  We  also  rely  on  trade  secrets,  security  measures  and
careful monitoring of our proprietary information to protect aspects of our business that are not amenable to, or that we do
not consider appropriate for, patent protection.

We  expect  that  our  probability  of  success  will  be  significantly  enhanced  by  our  ability  to  obtain  and  maintain
patent  and  other  proprietary  protection  for  commercially  important  technology,  inventions  and  know-how  related  to  our
business, defend and enforce our patents, maintain our licenses to use intellectual property owned by third parties, preserve
the  confidentiality  of  our  trade  secrets  and  operate  without  infringing  the  valid  and  enforceable  patents  and  other
proprietary  rights  of  third  parties.  We  also  rely  on  know-how,  continuing  technological  innovation  and  in-licensing
opportunities to develop, strengthen and maintain our proprietary position in the field of AAV-based gene therapies.

In  some  cases,  we  are  dependent  on  the  patented  or  proprietary  technology  of  third  parties  to  develop  and
commercialize  our  products.  We  must  obtain  licenses  from  such  third  parties  on  commercially  reasonable  terms,  or  our
business could be harmed, possibly materially. For example, we license from third parties essential parts of the therapeutic
gene cassettes as well as the principal AAV vectors we use and key elements of our manufacturing process. We anticipate
that we will require additional licenses in the future.

Because most patent applications throughout the world are confidential for 18 months after the earliest claimed
priority date, and since the publication of discoveries in the scientific and patent literature often lags actual discoveries, we
cannot  be  certain  that  we  were  the  first  to  invent  or  file  applications  for  the  inventions  covered  by  our  pending  patent
applications. Moreover, we may have to participate in post-grant proceedings in the patent offices of the United States or
foreign  jurisdictions,  such  as  oppositions,  reexaminations,  or  interferences,  in  which  the  patentability  or  priority  of  our
inventions are challenged. Such proceedings could result in substantial cost, even if the eventual outcome is favorable to
us.

Our  intellectual  property  portfolio  consists  of  owned  and  in-licensed  patents,  copyrights,  licenses,  trademarks,

trade secrets and other intellectual property rights.

Patent Portfolio

Our  gene  therapy  programs  are  protected  by  patents  and  patent  applications  directed  to  various  aspects  of  our
technology. For example, our gene therapy programs are protected by patents and patent applications with composition-of-
matter or method of use claims that cover the therapeutic gene, the promoter, the viral vector capsid, or other specific parts
of  these  technologies.  We  also  seek  protection  of  core  aspects  of  our  manufacturing  process,  particularly  regarding  our
baculovirus expression system for AAV vectors in insect cells. In addition, we have filed manufacturing patent applications
with  claims  directed  to  alternative  compositions-of-matter  and  manufacturing  processes  to  seek  better  protection  from
competitors.

We file the initial patent applications for our commercially important technologies in both Europe and the United
States. For the same technologies, we typically file international patent applications under the PCT within a year. We also
may seek, usually on a case-by-case basis, local patent protection in Canada, Australia, Japan, China, India, Israel, South
Africa, New Zealand, South Korea, and Eurasia, as well as South American jurisdictions such as Brazil and Mexico.

Table of Contents

As  of  December  31,  2021,  our  intellectual  property  portfolio  included  105  issued  patents  (including  27  U.S.
patents and 10 patents granted by the European Patent Office (“EPO”) and 120 pending patent applications (including 24
U.S. patent applications and 23 EPO patent applications.

These patents relate to a variety of technologies including our product candidates that are in development and our

manufacturing and technology platform.

Our Patent Portfolio Related to Certain Development Programs

Hemophilia B (AMT-061)

We own a patent family, including patents and patent applications, directed to the use of the Padua mutation in

hFIX for gene therapy in etranacogene dezaparvovec.

Huntington’s disease (AMT-130)

We own two patent families directed to gene therapy treatment of Huntington’s disease, including with AMT-130.
This miQURE gene silencing technology platform is designed to degrade disease-causing genes, without off-target toxicity,
and induce silencing of the entire target organ through secondary exosome-mediated delivery.

Licenses

We  have  obtained  exclusive  or  non-exclusive  rights  from  third  parties  under  a  range  of  patents  and  other
technology  that  we  use  in  our  product  and  development  programs,  as  described  below.  Our  agreements  with  these  third
parties generally grant us a license to make, use, sell, offer to sell, and import products covered by the licensed patent rights
in exchange for our payment of some combination of an upfront amount, annual fees, royalties, a percentage of amounts
we  receive  from  our  licensees  and  payments  upon  the  achievement  of  specified  development,  regulatory  or  commercial
milestones. Some of the agreements specify the extent of the efforts we must use to develop and commercialize licensed
products. The agreements generally expire upon expiration of the last-to-expire valid claim of the licensed patents. Each
licensor may terminate the applicable agreement if we materially breach our obligations and fail to cure the breach within a
specified cure period.

Technology Used for Multiple Programs

We are exploiting technology from third-party sources described below in more than one of our programs.

Cold Spring Harbor Laboratory

In 2015, we entered into a license agreement with CSHL in which CSHL granted to us an exclusive, sublicensable
license to develop and commercialize certain of CSHL’s patented RNAi-related technology for use in connection with the
treatment or prevention of Huntington’s disease. The standard 20-year patent term for the licensed patents expires in 2031.

In 2018, we entered into an amendment of the license agreement with CSHL that expanded the license to include
the diagnosis, treatment, or prevention of all CNS diseases in the Field, including but not limited to Huntington’s disease.
In addition, under the amended license agreement CSHL granted to us an exclusive license for a three-year term to develop
and  commercialize  therapeutic  products  for  the  additional  disease  classifications  in  the  Field  of  liver  diseases,
neuromuscular diseases, and cardiovascular diseases. If we meet certain diligence milestones during the initial three-year
development  term,  we  may  include  exclusively  additional  disease  classifications  within  the  additional  Fields  on  similar
terms and conditions as the CNS diseases.

21

Table of Contents

Under this license agreement, annual fees, development milestone payments and future single-digit royalties on

net sales of a licensed product are payable to CSHL.

Protein Sciences

In 2016, we revised our existing license contract with Protein Sciences Corporation for the use of its expresSF+
insect  cell  line  and  associated  technology  for  human  therapeutic  and  prophylactic  uses  (except  influenza)  to  provide  us
with a royalty free, perpetual right and license to the licensed technology in the field of AAV-based gene therapy.

National Institutes of Health—AAV production

In 2007, we entered into a non-exclusive license agreement with the NIH, which we amended in 2009 and 2013.
The  patents  under  this  license  cover  technology  to  produce  AAV  vectors  in  insect  cells.  We  may  only  grant  sublicenses
under this agreement with the NIH’s consent, which may not be unreasonably withheld. The standard 20-year term for the
underlying patents will expire in 2022.

Payment obligations to the NIH under this license agreement include a low single-digit percentage royalty on the
net  sales  of  licensed  products  by  us  or  on  our  behalf;  development  and  regulatory  milestone  payments;  and  an  annual
maintenance fee creditable against royalties. We do not have to pay royalties or milestone fees under this agreement if we
must pay royalties or milestone fees under our 2011 agreement with the NIH, described below, for the same product. Under
the license agreement, we have agreed to meet benchmarks in our development efforts, including as to development events,
clinical trials, and marketing approval, within specified timeframes.

The NIH may terminate this agreement in specified circumstances relating to our insolvency or bankruptcy. We

may terminate this agreement for any reason, in any territory, subject to a specified notice period.

National Institutes of Health—AAV5

In  2011,  we  entered  into  another  license  agreement  with  the  NIH,  superseding  the  2007  agreement.  This
agreement  was  amended  in  2016.  Under  this  agreement,  the  NIH  granted  us  an  exclusive,  worldwide  license  to  patents
relating  to  AAV5  for  use  in  therapeutic  products  to  be  delivered  to  the  brain  or  liver  for  treatment  of  human  diseases
originating in the brain or liver but excluding arthritis-related diseases, and a non-exclusive, worldwide license to patents
relating to AAV5 for all other diseases. We refer to the products licensed under this agreement as AAV5 products. We may
grant  sublicenses  under  this  agreement  only  with  the  NIH’s  consent,  which  may  not  be  unreasonably  withheld.  The  last
patent under this license expired in July 2021.

Payment  obligations  to  the  NIH  under  this  license  agreement  include  royalties  equal  to  a  low  single-digit
percentage of net sales of AAV5 products; development and regulatory milestone payments; and an annual maintenance fee
creditable against royalties. If an AAV5 product is also covered by our 2007 agreement with the NIH, our obligation to pay
royalties  on  net  sales  and  our  obligation  to  pay  milestone  fees  only  apply  under  this  2011  agreement  and  not  the  2007
agreement. We have agreed to meet benchmarks in our development efforts, including as to development events, clinical
trials, and marketing approval, within specified timeframes.

Technology Used for Specific Development Programs

Hemophilia B

Padua

On  April  17,  2017,  we  entered  into  an  Assignment  and  License  Agreement  with  Dr.  Simioni  (the  “Padua
Assignment”).  Pursuant  to  the  Padua  Assignment,  we  acquired  from  Dr.  Simioni  all  right,  title  and  interest  in  a  patent
family  covering  the  variant  of  the  FIX  gene,  carrying  an  R338L  mutation  (FIX-Padua;  “Padua  IP”).  Under  the  Padua
Assignment,  we  have  also  licensed  certain  know-how  included  in  the  Padua  IP.  We  have  provided  Dr.  Simioni  with  an
initial license fee and reimbursement of past expenses. Under the agreement, additional payments may come due upon the
achievement  of  certain  milestone  events  related  to  the  development  of  the  Padua  IP  or  as  royalties  on  a  percentage  of
certain  revenues.  We  have  granted  a  license  of  the  Padua  IP  back  to  Dr.  Simioni  for  therapeutic  or  diagnostic  use  of  a
modified Factor IX protein (other than in connection with gene therapy) and any application for non-commercial research
purposes.  We  have  agreed  to  indemnify  Dr.  Simioni  for  claims  arising  from  our  research,  development,  manufacture,  or
commercialization of any product making use of the Padua IP, subject to certain conditions. The Padua Assignment will
remain  in  effect,  unless  otherwise  terminated  pursuant  to  the  terms  of  the  Padua  Assignment,  until  the  later  of  (i)  the
expiration date of the last of the patents within the Padua IP and (ii) the expiration of the payment obligations under the
Padua Assignment.

St. Jude Children’s Research Hospital

In 2008, we entered into a license agreement with St. Jude Children’s Research Hospital (“St. Jude”), which we
amended in 2012. Under this license agreement, St. Jude has granted us an exclusive license, with a right to sublicense, to
patent rights relating to expression of hFIX in gene therapy vectors, to make, import, distribute, use, and commercialize
products  containing  hFIX  covered  by  a  valid  patent  claim  in  the  field  of  gene  therapy  for  treatment  or  prophylaxis  of
hemophilia B. In addition, we have a first right of negotiation regarding any patent applications that are filed by St. Jude
for  any  improvements  to  the  patent  rights  licensed  to  us.  The  U.S.  patent  rights  will  expire  in  2028  and  the  European
patents will expire in 2025.

We have agreed to pay St. Jude a royalty equal to a low single-digit percentage of net sales, if any, by us or our
sublicensees  of  products  covered  by  the  licensed  patent  rights,  and  a  portion  of  certain  amounts  we  receive  from
sublicensees ranging from a mid-single digit to a mid-teen double-digit percentage of such amounts. With respect to our
collaboration with CSL Behring, we have agreed with St. Jude on an apportionment of certain amounts we receive from
CSL Behring as sublicensing revenue that is equivalent to a low-single digit percentage of such amounts.

We have also agreed to pay St. Jude a one-time milestone of $5.0 million upon the BLA and MAA approval, and

an annual maintenance fee creditable against royalties and milestones in the same year.

The  agreement  will  remain  in  effect  until  no  further  payment  is  due  relating  to  any  licensed  product  under  this
agreement or either we or St. Jude exercise our rights to terminate it. St. Jude may terminate the agreement in specified
circumstances  relating  to  our  insolvency.  We  may  terminate  the  agreement  for  convenience  at  any  time  subject  to  a
specified notice period.

Temporal Lobe Epilepsy

Regenxbio

In  June  2020,  Corlieve  entered  into  an  agreement,  subsequently  amended  in  June  2021,  with  Regenxbio  for  an
exclusive (in the field of using AAV9 to expression of the GRIK 2 gene in humans (the “Field”)), sublicensable, royalty-
bearing,  worldwide  license  under  Regenxbio’s  interest  in  EU  patent  application  19185533.7  (the  “Foreground  Patents”)
and  related  patents,  as  well  as  patents  covering  inventions  developed  during  the  collaboration  and  certain  patents  and
know-how relating to AAV9 (the “Background Technology”). The license also includes non-exclusive rights to exploit the
licensed  Foreground  Patents  and  certain  related  patents  know-how  developed  in  collaboration  pursuant  to  the  license
agreement  outside  the  Field.  The  license  also  includes  retained  and  license  back  rights  that  permit  Regenxbio  and  its
upstream  licensors  to  exploit  for  any  research,  development,  commercialization,  or  other  purposes  certain  patents,
inventions and know-how (other than the Foreground Patents) subject to or created pursuant to the license agreement.

Payment obligations under the agreement provide for royalty payments on net sales in the mid-single digit to low-
double  digits,  and  milestone  payments  to  Regenxbio  in  the  mid-tens  of  millions  of  dollars  related  to  clinical  trials,
commercialization, and net sales. The agreement also calls for sublicense fees in the low-double digit range. The royalty is
paid  on  sales  of  license  products  using  any  of  licensed  patents  or  know-how  for  as  long  as  the  agreement  is  in  effect.
Royalty  and  milestone  payments  may  continue  to  be  owed  under  the  license  following  termination  of  the  agreement  if
licensed  products  are  sold  following  termination  of  the  license.  Under  the  agreement,  Corlieve  has  certain  diligence
obligations and Regenxbio has certain obligations related to the pre-clinical development of manufacturing technology.

Inserm Transfert

In January 2020, Corlieve entered into license agreement with Inserm Transfert SA (also acting as a delegate for
the  French  National  Institute  of  Health  and  Medical  Research)  and  La  societe  SATT  Aquitaine  (the  counterparties
collectively  referred  to  as  “Inserm  Transfert”).  Under  the  license  agreement,  Corlieve  is  granted  an  exclusive,
sublicensable, royalty-bearing, worldwide license under European Patent (“EP”) patent application 13306265.3 in the field
of the prevention and treatment of epilepsy, and in Inserm Transfert’s share in EP patent application 19185533.7 (which is
co-owned  by  Regenxbio)  in  the  field  of  all  human  use.  Corlieve  also  is  granted  a  non-exclusive,  sublicensable,  royalty-
bearing,  worldwide  license  under  certain  know-how  in  the  fields  that  may  be  developed  by  Inserm  pursuant  to  the
agreements. Under the agreements, Inserm retains certain rights for teaching, academic and/or research purposes.

Payment obligations under the agreements include a royalty on the net sales of license products in the low single
digits, milestone payments associated with clinical trial and regulatory approval milestones of multiple licensed products
totaling in the low-single digit millions of Euros. The agreement also calls for sublicense fees in the low to mid double-
digit  range  depending  on  the  timing  of  such  sublicense.  The  obligation  to  pay  royalties  extends  until  the  later  of  the
expiration of the patent rights, any regulatory exclusivity period, and 10 years from the first commercial sale of a licensed
product.

Trade Secrets

In  addition  to  patents  and  licenses,  we  rely  on  trade  secrets  and  know-how  to  develop  and  maintain  our
competitive  position.  For  example,  significant  aspects  of  the  process  by  which  we  manufacture  our  gene  therapies  are
based on unpatented trade secrets and know-how. We seek to protect our proprietary technology and processes and obtain
and  maintain  ownership  of  certain  technologies,  in  part,  through  confidentiality  agreements  and  invention  assignment
agreements with our employees, consultants, scientific advisors, contractors and commercial collaborator. We also seek to
preserve the integrity and confidentiality of our data, trade secrets and know-how by maintaining physical security of our
premises and physical and electronic security of our information technology systems.

Trademarks

We  have  a  number  of  material  registered  trademarks,  including  “uniQure”,  that  we  have  registered  in  various
jurisdictions  including  the  United  States  and  the  European  Union.  We  may  seek  trademark  protection  for  other  product
candidates and technologies as and when appropriate.

Competition

The biotechnology and pharmaceutical industries, including in the gene therapy field, are characterized by rapidly
advancing  technologies,  intense  competition,  and  a  strong  emphasis  on  intellectual  property.  We  face  substantial
competition  from  many  different  sources,  including  large  and  specialty  pharmaceutical  and  biotechnology  companies,
academic research institutions and governmental agencies and public and private research institutions.

We face worldwide competition from larger pharmaceutical companies, specialty pharmaceutical companies and
biotechnology  firms,  universities  and  other  research  institutions  and  government  agencies  that  are  developing  and
commercializing  pharmaceutical  products.  Our  key  competitors  focused  on  developing  therapies  in  various  indications,
include  among  others,  Pfizer,  Freeline  Therapeutics,  Intellia  Therapeutics,  Sangamo  Biosciences,  Voyager  Therapeutics,
Passage  Bio,  Roche,  PTC  Therapeutics,  Prilenia  Therapeutics,  Triplet  Therapeutics,  CombiGene,  AvroBio,  Caritas
Therapeutics, and 4D Molecular Therapeutics.

24

Table of Contents

We  also  compete  with  existing  standards  of  care,  therapies,  and  symptomatic  treatments,  as  well  as  any  new

therapies that may become available in the future for the indications we are targeting.

Many of our current or potential competitors, either alone or with their collaborators, have significantly greater
financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials
and  marketing  approved  products  than  we  do.  Mergers  and  acquisitions  in  the  pharmaceutical,  biotechnology  and  gene
therapy  industries  may  result  in  even  more  resources  being  concentrated  among  a  smaller  number  of  our  competitors.
Smaller  or  early-stage  companies  may  also  prove  to  be  significant  competitors,  particularly  through  collaborative
arrangements  with  large  and  established  companies.  These  competitors  also  compete  with  us  in  recruiting  and  retaining
qualified scientific and management personnel and establishing clinical trial sites and patient registration for clinical trials,
as well as in acquiring technologies complementary to, or necessary for, our programs.

The  key  competitive  factors  affecting  the  success  of  all  our  programs  are  likely  to  be  their  efficacy,  safety,
convenience, price, and the availability of reimbursement from government and other third-party payers. We also believe
that,  due  to  the  small  size  of  the  patient  populations  in  the  orphan  indications  we  target,  being  first  to  market  will  be  a
significant competitive advantage. We believe that our advantages in vector and manufacturing technology will allow us to
reach market in a number of indications ahead of our competitors, and to capture the markets in these indications.

Government Regulation and Reimbursement

Government  authorities  in  the  United  States,  European  Union  and  other  countries  extensively  regulate,  among
other  things,  the  approval,  research,  development,  preclinical  and  clinical  testing,  manufacture  (including  any
manufacturing changes), packaging, storage, recordkeeping, labeling, advertising, promotion, distribution, marketing, post-
approval monitoring and reporting, reimbursement, and import and export of pharmaceutical products, biological products,
and medical devices. We believe that all our product candidates will be regulated as biological products, or biologics, and
in particular, as gene therapies, and will be subject to such requirements and regulations under U.S. and foreign laws. For
other countries outside of the United States and the European Union, marketing approval and pricing and reimbursement
requirements  vary  from  country  to  country.  If  we  fail  to  comply  with  applicable  regulatory  requirements,  we  may  be
subject  to,  among  other  things,  fines,  refusal  to  approve  pending  applications,  suspension  or  withdrawal  of  regulatory
approvals, product recalls, seizure of products, operating restrictions, and criminal prosecution.

Regulation in the United States

In the United States, the FDA regulates biologics under the Public Health Service Act (“PHSA”) and the Federal
Food,  Drug,  and  Cosmetic  Act  (“FDCA”)  and  regulations  and  guidance  implementing  these  laws.  These  laws  and
regulatory guidance are continually evolving. By example, in March 2020, the U.S. Congress passed the Coronavirus Aid,
Relief,  and  Economic  Security  Act,  or  CARES  Act,  which  includes  various  provisions  regarding  FDA  drug  shortage
reporting requirements, as well as provisions regarding supply chain security, such as risk management plan requirements,
and  the  promotion  of  supply  chain  redundancy  and  domestic  manufacturing.  The  FDA  has  also  issued  a  number  of
guidance documents concerning how sponsors and investigators may address COVID-19 challenges, including challenges
specific to gene therapies. These guidance documents are continually evolving.

Obtaining  regulatory  approvals  and  ensuring  compliance  with  applicable  statutes  and  regulatory  requirements
entails the expenditure of substantial time and financial resources, including payment of user fees for applications to the
FDA. All our current product candidates are subject to regulation by the FDA as biologics. An applicant seeking approval
to market and distribute a new biologic in the United States must typically undertake the following:

● completion  of  preclinical  laboratory  tests,  animal  studies  and  formulation  studies  in  compliance  with  the

FDA’s current Good Laboratory Practice regulations;

● submission to the FDA of an IND application which allows human clinical trials to begin unless the FDA
objects within 30 days; the sponsor of an IND or its legal representative must be based in the United States

● approval  by  an  independent  institutional  review  board  (“IRB”)  and  Institutional  Biosafety  Committee

(“IBC”) before each clinical trial may be initiated;

● performance  of  adequate  and  well-controlled  human  clinical  trials  in  accordance  with  the  FDA’s  cGCP  to
establish substantial evidence of the safety and efficacy proposed biological product for each indication;

25

Table of Contents

● preparation and submission to the FDA of a BLA;

● satisfactory completion of one or more FDA inspections of the manufacturing facility or facilities at which
the  product,  or  components  thereof,  are  produced  to  assess  compliance  with  cGMP  requirements  and  to
assure  that  the  facilities,  methods,  and  controls  are  adequate  to  preserve  the  product’s  identity,  strength,
quality, and purity, as well as selected clinical trial sites and investigators to determine cGCP compliance;

● approval of the BLA by the FDA, in consultation with an FDA advisory committee, if deemed appropriate by

the FDA; and

● compliance  with  any  post-approval  commitments,  including  Risk  Evaluation  and  Mitigation  Strategies

(“REMS”), and post-approval studies required by the FDA.

Human Clinical Studies in the United States under an IND

Before initiating clinical studies in the United States or under an IND, investigational product sponsors must first
complete  pre-clinical  studies.  Preclinical  studies  include  laboratory  evaluation  of  chemistry,  pharmacology,  toxicity,  and
product  formulation,  as  well  as  animal  studies  to  assess  potential  safety  and  efficacy.  Such  studies  must  generally  be
conducted in accordance with the FDA’s Good Laboratory Practices (“GLPs”).

Clinical trials involve the administration of the investigational biologic to human subjects under the supervision of
qualified investigators in accordance with current GCP requirements, which includes requirements for informed consent,
study conduct, and IRB review and approval. A protocol for each clinical trial and any subsequent protocol amendments
must  be  submitted  to  the  FDA  as  part  of  an  IND.  INDs  include  preclinical  study  reports,  together  with  manufacturing
information,  analytical  data,  any  available  clinical  data,  or  literature,  and  proposed  clinical  study  protocols  among  other
things. A clinical trial may not proceed in the United States unless and until an IND becomes effective, which is 30 days
after its receipt by the FDA. The FDA may raise concerns or questions related to one or more components of an IND and
place the IND on clinical hold if during its review the FDA determines that study subjects would be exposed to significant
risk of illness or injury. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the
clinical trial can begin. Clinical holds also may be imposed by the FDA at any time before or during trials due to safety
concerns or non-compliance.

The protocol and informed consent documents, as well as other subject communications must also be approved by
an IRB that continues to oversee that trial. In the case of gene therapy studies, an IBC at the local level must also review
and maintain oversight over the particular study, in addition to the IRB. The FDA, an IRB, and IBC, or the sponsor may
suspend or terminate a clinical trial at any time on various grounds, including a finding that the research subjects are being
exposed to an unacceptable health risk or that research requirements are not being met. Information about certain clinical
trials,  including  results,  must  be  submitted  within  specific  timeframes  for  listing  on  the  ClinicalTrials.gov  website.
Sponsors  or  distributors  of  investigational  products  for  the  diagnosis,  monitoring,  or  treatment  of  one  or  more  serious
diseases or conditions must also have a publicly available policy on evaluating and responding to requests for expanded
access.  Investigators  must  also  provide  certain  information  to  the  clinical  trial  sponsors  to  allow  the  sponsors  to  make
certain financial disclosures to the FDA.

Subsequent clinical protocols and amendments must also be submitted to an active IND but are not subject to the
30-day review period imposed on an original IND. Progress reports detailing the results of the clinical trials must also be
submitted at least annually to the FDA and the IRB and more frequently if serious adverse events or other significant safety
information is found. There is a risk that once a new protocol or amendment is submitted to an active IND there may be an
extended  period  before  the  FDA  may  comment  or  provide  feedback.  This  may  result  in  a  need  to  modify  an  ongoing
clinical trial to incorporate this feedback or even a clinical hold of the trial. There is also risk that FDA may not provide
comments or feedback but may ultimately disagree with the design of the study once a BLA is submitted.

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

● Phase I: The biological product is initially introduced into healthy human subjects or patients with the target
disease or condition and tested for safety, dosage tolerance, absorption, metabolism, distribution, excretion
and, if possible, to gain an early understanding of its effectiveness.

● Phase II: The biological product is administered to a limited patient population to further identify possible
adverse  effects  and  safety  risks,  to  preliminarily  evaluate  the  efficacy  of  the  product  for  specific  targeted
diseases and to determine dosage tolerance and optimal dosage.

● Phase  III:  The  biological  product  is  administered  to  an  expanded  patient  population,  generally  at
geographically  dispersed  clinical  trial  sites,  in  adequate  and  well-controlled  clinical  trials  to  generate
sufficient  data  to  statistically  confirm  the  potency  and  safety  of  the  product  for  approval,  to  establish  the
overall  risk-benefit  profile  of  the  product  and  to  provide  adequate  information  for  the  labelling  of  the
product.  Typically,  two  Phase  3  trials  are  required  by  the  FDA  for  product  approval.  Under  some  limited
circumstances,  however,  the  FDA  may  approve  a  BLA  based  upon  a  single  Phase  3  clinical  study  plus
confirmatory evidence or a single large multicenter trial without confirmatory evidence.

In addition, under the Pediatric Research Equity Act, or PREA, a BLA or BLA supplement for a new active
ingredient, indication, dosage form, dosage regimen, or route of administration, must contain data that are adequate to
assess the safety and effectiveness of the product for the claimed indications in all relevant pediatric subpopulations, and to
support dosing and administration for each pediatric subpopulation for which the product is safe and effective. The FDA
may, on its own initiative or at the request of the applicant, grant deferrals for submission of some or all pediatric data until
after approval of the product for use in adults, or full or partial waivers from the pediatric data requirements. Orphan
products are also exempt from the PREA requirements.

The manufacture of investigational drugs and biologics for the conduct of human clinical trials is subject to cGMP

requirements. Investigational drugs and biologics and active ingredients and therapeutic substances imported into the
United States are also subject to regulation by the FDA. Further, the export of investigational products outside of the
United States is subject to regulatory requirements of the receiving country as well as U.S. export requirements under the
FDCA.

Concurrent with clinical trials, companies usually complete additional animal studies and must also develop
additional information about the chemistry and physical characteristics of the product candidate as well as finalize a
process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The
manufacturing process must be capable of consistently producing quality batches of the product candidate and, among
other things, manufacturers must develop methods for testing the identity, strength, quality, potency, and purity of the final
product. Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted to
demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.

Regulation and FDA Guidance Governing Gene Therapy Products

The  FDA  has  and  continues  to  issue  various  guidance  documents  with  respect  to  the  development  and
commercialization of gene therapies. These include guidance on, among other things, the proper preclinical and nonclinical
assessment  of  gene  therapies;  the  chemistry,  manufacturing,  and  controls;  the  design  and  conduct  of  clinical  trials;  the
design and analysis of shedding studies for virus or bacteria based gene therapies; the proper design of tests to measure
product potency in support of an IND or BLA application; and measures to observe delayed adverse effects in subjects and
patients who have been exposed to gene therapies via long-term follow-up with associated regulatory reporting. The FDA
has also issued guidance documents specific to gene therapies during the COVID-19 public health emergency, including
one on manufacturing considerations and the conduct of risk assessments. FDA has further issued guidance focused on the
development of gene therapies for the treatment of rare neurodegenerative diseases, rare diseases, and hemophilia, as such
products may face special challenges.

Certain  gene  therapy  studies  are  also  subject  to  the  National  Institutes  of  Health’s  Guidelines  for  Research
Involving Recombinant DNA Molecules, (“NIH Guidelines”). The NIH Guidelines include the review of the study by an
IBC.  The  IBC  assesses  the  compliance  of  the  research  with  the  NIH  Guidelines,  assesses  the  safety  of  the  research  and
identifies any potential risk to public health or the environment.

27

Table of Contents

Compliance with cGMP Requirements

Manufacturers of biologics must comply with applicable cGMP regulations, including quality control and quality
assurance  and  maintenance  of  records  and  documentation.  Manufacturers  and  others  involved  in  the  manufacture  and
distribution of such products must also register their establishments with the FDA and certain state agencies, and provide
the  FDA  a  list  of  products  manufactured  at  the  facilities.  Recently,  the  information  that  must  be  submitted  to  the  FDA
regarding manufactured products was expanded through the Coronavirus Aid, Relief, and Economic Security, or CARES,
Act to include the volume of drugs produced during the prior year. Establishments may be subject to periodic unannounced
inspections  by  government  authorities  to  ensure  compliance  with  cGMPs  and  other  laws.  Discovery  of  non-compliance
may result in the FDA placing restrictions on a product, manufacturer, or holder of an approved BLA, and may extend to
requiring withdrawal of the product from the market, among other consequences. The FDA will not approve an application
unless  it  determines  that  the  manufacturing  processes  and  facilities  are  in  compliance  with  cGMP  requirements  and
adequate to assure consistent production of the product within required specifications.

FDA Programs to Expedite Product Development

The  FDA  has  several  programs  to  expedite  product  development,  including  fast  track  designation  and
breakthrough therapy designation. These are outlined in specific FDA guidance. Under the fast track program, the sponsor
of  a  biologic  candidate  may  request  the  FDA  to  designate  the  product  for  a  specific  indication  as  a  fast  track  product
concurrent with or after the filing of the IND for the product candidate. To be eligible for a fast track designation, the FDA
must  determine  that  a  product  candidate  is  intended  to  treat  a  serious  or  life-threatening  disease  or  condition  and
demonstrates the potential to address an unmet medical need. This may be demonstrated by clinical or nonclinical data. If
granted, the benefits include greater interactions with the FDA and rolling review of sections of the BLA. In some cases, a
fast track product may be eligible for accelerated approval or priority review.

Moreover, under the provisions of the Food and Drug Administration Safety and Innovation Act, enacted in 2012,
a sponsor can request designation of a product candidate as a breakthrough therapy. A breakthrough therapy is defined as a
product  that  is  intended,  alone  or  in  combination  with  one  or  more  other  products,  to  treat  a  serious  or  life-threatening
disease or condition, and preliminary clinical evidence indicates that the product may demonstrate substantial improvement
over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early
in clinical development. Products designated as breakthrough therapies are eligible for rolling review, intensive guidance
on  an  efficient  development  program  beginning  as  early  as  Phase  1  trials,  and  a  commitment  from  the  FDA  to  involve
senior managers and experienced review staff in a proactive collaborative, cross disciplinary review.

Biologics studied for their safety and effectiveness in treating serious or life-threatening illnesses and that provide
meaningful  therapeutic  benefit  over  existing  treatments  may  receive  accelerated  approval,  which  means  the  FDA  may
approve the product 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. A biologic candidate approved on this basis is subject to
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 studies, or confirm a clinical benefit
during post-marketing studies, will allow the FDA to withdraw the drug or biologic from the market on an expedited basis.
All  promotional  materials  for  drug  or  biologic  candidates  approved  under  accelerated  regulations  are  subject  to  prior
review by the FDA. In recent years, the accelerated approval pathway has come under significant FDA and public scrutiny.
Accordingly,  the  FDA  may  be  more  conservative  in  granting  accelerated  approval  or,  if  granted,  may  be  more  apt  to
withdrawal approval if clinical benefit is not confirmed.

Even  if  a  product  qualifies  for  one  or  more  of  these  programs,  the  FDA  may  later  decide  that  the  product  no
longer  meets  the  conditions  for  qualification  or  decide  that  the  time  period  for  FDA  review  or  approval  will  not  be
shortened.

28

Table of Contents

Submission of a BLA

The  results  of  the  preclinical  and  clinical  studies,  together  with  detailed  information  relating  to  the  product’s
chemistry, manufacture, controls, and proposed labeling, among other things, are submitted to the FDA as part of a BLA
requesting  a  license  to  market  the  product  for  one  or  more  indications.  The  submission  of  a  BLA  is  subject  to  an
application  user  fee,  though  products  with  orphan  designation  are  exempt  from  the  BLA  filing  fee.  The  sponsor  of  an
approved  BLA  is  also  subject  to  annual  program  user  fees.  Orphan  products  may  also  be  exempt  from  program  fees
provided that certain criteria are met. These fees are typically increased annually. Under the Prescription Drug User Fee
Act (“PDUFA”) the FDA has agreed to specified performance goals in the review of BLAs.

Most  such  applications  are  meant  to  be  reviewed  within  ten  months  from  the  filing  acceptance  date  (typically
60 days after date of filing), and most applications for priority review products are meant to be reviewed within six months
of the filing acceptance date (typically 60 days after date of filing). Priority review designation may be assigned to product
candidates  that  are  intended  to  treat  serious  conditions  and,  if  approved,  would  provide  significant  improvements  in  the
safety or effectiveness of the treatment, diagnosis, or prevention of the serious condition.

The FDA may refuse to file an application and request additional information. In this event, the application must
be refiled with the additional information. The refiled application is also subject to assessment of content before the FDA
accepts  it  for  review.  Once  the  submission  is  accepted,  the  FDA  begins  an  in-depth  substantive  review.  The  FDA  will
assign a date for its final decision for the product (the PDUFA action date) but can extend this date to complete review of a
product  application  or  to  consider  additional  information  submitted  during  the  application  review  period.  The  PDUFA
action  date  is  only  a  goal,  thus,  the  FDA  does  not  always  meet  its  PDUFA  dates.  Additionally,  this  review  period  may
change as the PDUFA statute must be reauthorized by Congress by September 2022.

The FDA may also refer certain applications to an advisory committee. Before approving a product candidate for
which no active ingredient (including any ester or salt of active ingredients) has previously been approved by the FDA, the
FDA must either refer that product candidate to an external advisory committee or provide in an action letter, a summary of
the  reasons  why  the  FDA  did  not  refer  the  product  candidate  to  an  advisory  committee.  The  FDA  may  also  refer  other
product  candidates  to  an  advisory  committee  if  the  FDA  believes  that  the  advisory  committee’s  expertise  would  be
beneficial. An advisory committee is typically a panel that includes clinicians and other experts, which review, evaluate,
and make a recommendation as to whether the application should be approved and under what conditions. The FDA is not
bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making
decisions.

The FDA reviews applications to determine, among other things, whether a product candidate meets the agency’s
approval standards and whether the manufacturing methods and controls are adequate to assure and preserve the product’s
identity, strength, quality, potency, and purity. Before approving a marketing application, the FDA typically will inspect
the facility or facilities where the product is manufactured, referred to as a Pre-Approval Inspection. The FDA will not
approve  an  application  unless  it  determines  that  the  manufacturing  processes  and  facilities,  including  contract
manufacturers  and  subcontractors,  are  in  compliance  with  cGMP  requirements  and  adequate  to  assure  consistent
production of the product within required specifications. Additionally, before approving a marketing application the FDA
will inspect one or more clinical trial sites to assure compliance with GCPs.

After  evaluating  the  marketing  application  and  all  related  information,  including  the  advisory  committee
recommendation, if any, and inspection reports regarding the manufacturing facilities and clinical trial sites, the FDA may
issue an approval letter or a complete response letter. An approval letter authorizes commercial marketing of the biological
product  with  specific  prescribing  information  for  specific  indications.  A  complete  response  letter  generally  outlines  the
deficiencies in the submission and may require substantial additional testing or information for the FDA to reconsider the
application. Even with submission of this additional information, the FDA ultimately may decide that the application does
not satisfy the regulatory criteria for approval. If and when those deficiencies have been addressed to the FDA’s satisfaction
in a resubmission of the BLA, the FDA will issue an approval letter. Many drug applications receive complete response
letters from the FDA during their first cycle of FDA review.

29

Table of Contents

If  the  FDA  approves  a  product,  it  may  limit  the  approved  indications  for  use  of  the  product;  require  that
contraindications,  warnings,  or  precautions  be  included  in  the  product  labeling,  including  boxed  warnings;  require  that
post-approval studies, including Phase IV clinical trials, be conducted to further assess a biologic’s efficacy and safety after
approval;  or  require  testing  and  surveillance  programs  to  monitor  the  product  after  commercialization.  The  FDA  may
prevent or limit further marketing of a product based on the results of post-market studies or surveillance programs. The
FDA may also not approve label statements that are necessary for successful commercialization and marketing.

In addition to the above conditions of approval, the FDA also may require submission of a REMS to ensure that
the  benefits  of  the  product  candidate  outweigh  the  risks.  The  REMS  plan  could  include  medication  guides,  physician
communication plans, and elements to assure safe use, such as restricted distribution methods, patient registries, or other
risk minimization tools. An assessment of the REMS must also be conducted at set intervals. Following product approval, a
REMS may also be required by the FDA if new safety information is discovered, and the FDA determines that a REMS is
necessary to ensure that the benefits of the product outweigh the risks. In guidance, FDA stated that during the review of a
BLA  for  a  gene  therapy,  it  will  assess  whether  a  REMS  is  necessary.  Several  gene  therapy  products  that  have  been
approved  by  FDA  have  required  substantial  REMS,  which  included  requirements  for  dispensing  hospital  and  clinic
certification, training, adverse event reporting, documentation, and audits and monitoring conducted by the sponsor, among
other  conditions.  REMS,  such  as  these,  can  be  expensive  and  burdensome  to  implement,  and  burdensome  for  hospitals,
clinics, and healthcare providers to comply with.

Biosimilars and Exclusivity

The Biologics Price Competition and Innovation Act of 2009 (“BPCIA”) which amended the PHSA authorized
the  FDA  to  approve  biosimilars  under  Section  351(k)  of  the  PHSA.  Under  the  BCPIA,  a  manufacturer  may  submit  an
application for licensure of a biologic product that is biosimilar to or interchangeable with a previously approved biological
product  or  reference  product.  For  the  FDA  to  approve  a  biosimilar  product,  it  must  find  that  it  is  highly  similar  to  the
reference  product  notwithstanding  minor  differences  in  clinically  inactive  components  and  that  there  are  no  clinically
meaningful  differences  between  the  reference  product  and  proposed  biosimilar  product  in  safety,  purity  or  potency.  A
finding of interchangeability requires that a product is determined to be biosimilar to the reference product, and that the
product  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.

An application for a biosimilar product may not be submitted to the FDA until four years following approval of
the  reference  product,  and  it  may  not  be  approved  until  12  years  thereafter.  These  exclusivity  provisions  only  apply  to
biosimilar companies and not companies that rely on their own data and file a full BLA. Moreover, this exclusivity is not
without limitation. Certain changes and supplements to an approved BLA, and subsequent applications filed by the same
sponsor, manufacturer, licensor, predecessor in interest, or other related entity do not qualify for the twelve-year exclusivity
period.  Further,  the  twelve-year  exclusivity  market  period  in  the  U.S.  for  biologics  has  been  controversial  and  may  be
shortened in the future.

The  PHSA  also  includes  provisions  to  protect  reference  products  that  have  patent  protection.  The  biosimilar
product  sponsor  and  reference  product  sponsor  may  exchange  certain  patent  and  product  information  for  the  purpose  of
determining  whether  there  should  be  a  legal  patent  challenge.  Based  on  the  outcome  of  negotiations  surrounding  the
exchanged  information,  the  reference  product  sponsor  may  bring  a  patent  infringement  suit  and  injunction  proceedings
against  the  biosimilar  product  sponsor.  The  biosimilar  applicant  may  also  be  able  to  bring  an  action  for  declaratory
judgment concerning the patent.

The  FDA  maintains  a  list  of  approved  biological  products,  which  is  commonly  referred  to  as  the  Purple  Book.
This  list  includes  product  names,  the  date  of  licensure,  and  any  periods  of  regulatory  exclusivity.  Additionally,  under  a
newly  enacted  statute  related  to  biological  product  patent  transparency,  following  the  exchange  of  patent  information
between  the  biosimilar  and  reference  product  sponsor,  the  reference  product  sponsor  must  also  provide  the  exchanged
patent information and patent expiry dates to the FDA. The FDA then publishes this information in the Purple Book.

To  increase  competition  in  the  drug  and  biologic  product  marketplace,  Congress,  the  executive  branch,  and  the
FDA have taken certain legislative and regulatory steps. By example, the FDA finalized a guidance to facilitate biologic
product  importation.  Moreover,  the  2020  Further  Consolidated  Appropriations  Act  included  provisions  requiring  that
sponsors  of  approved  biologic  products,  including  those  subject  to  REMS,  provide  samples  of  the  approved  products  to
persons  developing  biosimilar  products  within  specified  timeframes,  in  sufficient  quantities,  and  on  commercially
reasonable market-based terms. Failure to do so can subject the approved product sponsor to civil actions, penalties, and
responsibility for attorney’s fees and costs of the civil action. This same bill also includes provisions with respect to shared
and separate REMS programs.

Orphan Drug Exclusivity

Under  the  Orphan  Drug  Act  of  1983,  the  FDA  may  designate  a  biological  product  as  an  orphan  drug  if  it  is
intended  to  treat  a  rare  disease  or  condition  that  affects  fewer  than  200,000  individuals  in  the  United  States,  or  more  in
cases in which there is no reasonable expectation that the cost of developing and making a biological product available in
the  United  States  for  treatment  of  the  disease  or  condition  will  be  recovered  from  sales  of  the  product.  Additionally,
sponsors must present a plausible hypothesis for clinical superiority to obtain orphan drug designation if there is a product
already approved by the FDA that is considered by the FDA to be the same as the already approved product and is intended
for the same indication. This hypothesis must be demonstrated to obtain orphan exclusivity. With respect to gene therapies,
the FDA has issued a specific guidance on how the agency interprets its sameness regulations. Specifically, whether two
products are deemed to be the same by the FDA will depend on the products’ transgene expression, viral vectors groups
and variants, and additional product features that may contribute to therapeutic effect. Minor product differences will not,
generally, result in a finding that two products are different and there are some factors that FDA will consider on a case by
case  basis.  Any  of  the  FDA  sameness  determinations  could  impact  our  ability  to  receive  approval  for  our  product
candidates and to obtain or retain orphan drug exclusivity.

If a product with orphan designation receives the first FDA approval, it will be granted seven years of marketing
exclusivity,  which  means  that  the  FDA  may  not  approve  any  other  applications  for  the  same  product  for  the  same
indication  for  seven  years,  unless  clinical  superiority  is  demonstrated.  Competitors  may  receive  approval  of  different
products for the indication for which the orphan product has exclusivity and may obtain approval for the same product but
for  a  different  indication.  Orphan  product  designation  does  not  convey  any  advantage  in  or  shorten  the  duration  of  the
regulatory review and approval process. The FDA has granted orphan drug designation to AMT-130 for the treatment of
Huntington’s disease as well as for etranacogene dezaparvovec; meaning that they would receive orphan drug exclusivity if
they are the first products approved for their respective indications.

Pediatric Exclusivity

Under  the  Pediatric  Research  Equity  Act  of  2003,  pediatric  exclusivity  provides  for  the  attachment  of  an
additional six months of marketing protection to the term of any existing regulatory exclusivity in the US, including orphan
exclusivity  and  exclusivity  against  biosimilars.  This  six-month  exclusivity  may  be  granted  if  the  FDA  issues  a  written
request to the sponsor for the pediatric study, the sponsor submits a final study report after receipt of the written request
and meets the terms and timelines in the FDA’s written request.

Regenerative Advanced Therapy Designation

The 21st  Century  Cures  Act  became  law  in  December  2016  and  created  a  new  program  under  Section  3033  in
which  the  FDA  has  authority  to  designate  a  product  as  a  regenerative  medicine  advanced  therapy  (“RMAT”).  A  drug  is
eligible  for  a  RMAT  designation  if:  1)  it  is  a  regenerative  medicine  therapy  which  is  a  cell  therapy,  therapeutic  tissue
engineering product, human cell and tissue product, or any combination product using such therapies or products, except
those products already regulated under Section 361 of the PHSA; 2) the drug is intended to treat, modify, reverse, or cure a
serious or life-threatening disease or condition; and 3) preliminary clinical evidence indicates that the drug has the potential
to address unmet medical needs for such disease or condition. A RMAT must be made with the submission of an IND or as
an amendment to an existing IND. FDA will determine if a product is eligible for RMAT designation within 60 days of
submission.  Advantages  of  the  RMAT  designation  include  all  the  benefits  of  the  fast  track  and  breakthrough  therapy
designation programs, including early interactions with the FDA. These early interactions may be used to discuss potential
surrogate or intermediate endpoints to support accelerated approval. In 2019 the FDA stated in guidance that human gene
therapies, including genetically modified cells, that lead to a sustained effect on cells or tissues, may meet the definition of
a regenerative therapy.

FDA Regulation of Companion Diagnostics and Other Combination Products

We may seek to develop companion diagnostics for use in identifying patients that we believe will respond to our
gene therapies. Similarly, our product candidates may require delivery devices. A biologic product may be regulated as a
combination product if it is intended for use in conjunction with a medical device, such as a drug delivery device or an in
vitro diagnostic device. For combination products, the biologic and device components must, when used together, be safe
and effective and the product labeling must reflect their combined use. In some cases, the medical device component may
require  a  separate  premarket  submission.  Moreover,  clinical  trial  sponsors  using  investigational  devices  in  their  studies
must comply with FDA’s investigational device exemption regulations. Once approved or cleared, the device component
sponsor (or the combination product sponsor, if both components are covered by one application) must comply with the
FDA’s post-market device requirements, including establishment registration, device listing, device labeling, unique device
identifier, quality system regulation, medical device reporting, and reporting of corrections and removals requirements.

If  the  safety  or  effectiveness  of  a  biologic  product  is  dependent  on  the  results  of  a  diagnostic,  the  FDA  may
require that the in vitro companion diagnostic device and biologic product be contemporaneously approved, with labeling
that describes the use of the two products together. The type of premarket submission required for a companion diagnostic
device will depend on the FDA device classification. A premarket approval (“PMA”), application is required for high risk
devices classified as Class III; a 510(k) premarket notification is required for moderate risk devices classified as Class II;
and a de novo request may be used for novel devices not previously classified by the FDA that are low or moderate risk.
Except in some limited circumstances, the FDA generally will not approve a biologic that is dependent upon the use of a
companion diagnostic device if the device is not contemporaneously FDA-approved or -cleared.

Post-approval Requirements

Any products manufactured or distributed pursuant to the FDA approvals are subject to pervasive and continuing
regulation  by  the  FDA,  including,  among  other  things,  requirements  related  to  manufacturing,  recordkeeping,  and
reporting, including adverse experience reporting, deviation reporting, shortage reporting, and periodic reporting, product
sampling and distribution, advertising, marketing, promotion, certain electronic records and signatures, and post-approval
obligations imposed as a condition of approval, such as Phase 4 clinical trials, REMS, and surveillance to assess safety
and effectiveness after commercialization.

After approval, most changes to the approved product, such as adding new indications or other labeling claims,
are  subject  to  prior  FDA  review  and  approval.  There  also  are  continuing  annual  program  user  fee  requirements  for
approved products, excluding orphan products provided that certain criteria are met. Regulatory authorities may withdraw
product  approvals,  require  label  modifications,  or  request  product  recalls,  among  other  actions,  if  a  company  fails  to
comply  with  regulatory  standards,  if  it  encounters  problems  following  initial  marketing,  or  if  previously  unrecognized
problems are subsequently discovered.

Changes to the manufacturing process are strictly regulated and often require prior FDA approval or notification
before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and
specifications and impose reporting and documentation requirements upon the sponsor and any third-party manufacturers
that  the  sponsor  may  decide  to  use.  Accordingly,  manufacturers  must  continue  to  expend  time,  money,  and  effort  in
production and quality control to maintain cGMP compliance.

The FDA also strictly regulates marketing, labeling, advertising, and promotion of products that are placed on the
market. A company can make only those claims relating to a product that are approved by the FDA. Physicians, in their
independent professional medical judgment, may prescribe legally available products for unapproved indications that are
not  described  in  the  product’s  labeling  and  that  differ  from  those  tested  and  approved  by  the  FDA.  Biopharmaceutical
companies, however, are required to promote their products only for the approved indications and in accordance with the
provisions  of  the  approved  label.  The  FDA  and  other  agencies  actively  enforce  the  laws  and  regulations  prohibiting  the
promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to
significant  liability,  including,  but  not  limited  to,  criminal  and  civil  penalties  under  the  FDCA  and  False  Claims  Act,
exclusion  from  participation  in  federal  healthcare  programs,  mandatory  compliance  programs  under  corporate  integrity
agreements,  suspension  and  debarment  from  government  procurement  and  non-procurement  programs,  and  refusal  of
orders under existing government contracts.

In  addition,  the  distribution  of  prescription  biopharmaceutical  samples  is  subject  to  the  Prescription  Drug
Marketing Act (the “PDMA”), which regulates the distribution of samples at the federal level. Both the PDMA and state
laws limit the distribution of prescription biopharmaceutical product. Certain reporting related to samples is also required
and laws and regulations impose requirements to ensure accountability in distribution. Free trial or starter prescriptions
provided  through  pharmacies  are  also  subject  to  regulations  under  the  Medicaid  Drug  Rebate  Program  and  potential
liability under anti-kickback and false claims laws.

Moreover,  the  enacted  Drug  Quality  and  Security  Act  (“DQSA”),  imposes  obligations  on  sponsors  of
biopharmaceutical products related to product tracking and tracing. Among the requirements of this legislation, sponsors
are required to provide certain information regarding the products to individuals and entities to which product ownership is
transferred, are required to label products with a product identifier, and are required to keep certain records regarding the
product. The transfer of information to subsequent product owners by sponsors is also required to be done electronically.
Sponsors  must  also  verify  that  purchasers  of  the  sponsors’  products  are  appropriately  licensed.  Further,  under  this
legislation,  manufactures  have  product  investigation,  quarantine,  disposition,  and  notification  responsibilities  related  to
counterfeit, diverted, stolen, and intentionally adulterated products that would result in serious adverse health consequences
or  death  to  humans,  as  well  as  products  that  are  the  subject  of  fraudulent  transactions  or  which  are  otherwise  unfit  for
distribution  such  that  they  would  be  reasonably  likely  to  result  in  serious  health  consequences  or  death.  Similar
requirements  additionally  are  also  imposed  through  this  legislation  on  other  companies  within  the  biopharmaceutical
product supply chain, such as distributors and dispensers, as well as certain sponsor licensees and affiliates.

Later  discovery  of  previously  unknown  problems  with  a  product,  including  adverse  events  of  unanticipated
severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements before or after
approval, may result in significant regulatory actions. Such actions may include refusal to approve pending applications,
license or approval suspension or revocation, imposition of a clinical hold or termination of clinical trials, warning letters,
untitled  letters,  cyber  letters,  modification  of  promotional  materials  or  labeling,  provision  of  corrective  information,
imposition  of  post-market  requirements  including  the  need  for  additional  testing,  imposition  of  distribution  or  other
restrictions  under  a  REMS,  product  recalls,  product  seizures  or  detentions,  refusal  to  allow  imports  or  exports,  total  or
partial suspension of production or distribution, FDA debarment, injunctions, fines, consent decrees, corporate integrity
agreements,  suspension  and  debarment  from  government  procurement  and  non-procurement  programs,  and  refusal  of
orders  under  existing  government  contracts,  exclusion  from  participation  in  federal  and  state  healthcare  programs,
restitution, disgorgement, or civil or criminal penalties, including fines and imprisonment, and adverse publicity, among
other adverse consequences.

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 the results of all the manufacturer’s tests performed on
the  lot.  The  FDA  may  also  perform  certain  confirmatory  tests  on  lots  of  some  products  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.

Patent Term Restoration

If approved, biologic products may also be eligible for periods of U.S. patent term restoration. If granted, patent
term restoration extends the patent life of a single unexpired patent, that has not previously been extended, for a maximum
of five years. The total patent life of the product with the extension also cannot exceed fourteen years from the product’s
approval date. Subject to the prior limitations, the period of the extension is calculated by adding half of the time from the
effective date of an IND to the initial submission of a marketing application, and all the time between the submission of the
marketing application and its approval. This period may also be reduced by any time that the applicant did not act with due
diligence.

Anti-Kickback Provisions and other Fraud and Abuse Requirements

The federal Anti-Kickback Statute is a criminal statute that prohibits, among other things, knowingly and willfully
offering, paying, soliciting, or receiving remuneration directly or indirectly, overtly or covertly, in cash or in kind, to induce
or in return for purchasing, leasing, ordering, or arranging for the purchase, lease or order of any healthcare item or service
reimbursable  under  Medicare,  Medicaid  or  other  federally  financed  healthcare  programs,  in  whole  or  in  part.  The  term
“remuneration” has been interpreted broadly to include anything of value. The Anti-Kickback Statute has been interpreted
to apply to arrangements between biopharmaceutical industry members on the one hand and prescribers, purchasers, and
formulary managers on the other. The Beneficiary Inducement Civil Monetary Penalties Law imposes similar restrictions
on  interactions  between  the  biopharmaceutical  industry  and  federal  healthcare  program  beneficiaries.  There  are  certain
statutory  exceptions  and  regulatory  safe  harbors  to  the  Anti-Kickback  Statute  protecting  some  common  activities  from
prosecution.  The  exceptions  and  safe  harbors  are  drawn  narrowly,  and  practices  that  involve  remuneration  that  may  be
alleged to be intended to induce or reward prescribing, purchases, or recommendations may be subject to scrutiny if they
do  not  qualify  for  an  exception  or  safe  harbor.  Failure  to  meet  all  the  requirements  of  a  particular  applicable  statutory
exception or regulatory safe harbor does not make the conduct per se illegal under the Anti-Kickback Statute. Instead, the
legality  of  the  arrangement  will  be  evaluated  on  a  case-by-case  basis  based  on  a  cumulative  review  of  all  its  facts  and
circumstances.

Several courts have interpreted the statute’s intent requirement to mean that if any one purpose of an arrangement
involving  remuneration  is  to  induce  or  reward  referrals  of  federal  healthcare  program  business,  including  purchases  of
products  paid  by  federal  healthcare  programs,  the  statute  has  been  violated.  The  Patient  Protection  and  Affordable  Care
Act,  of  2010,  as  amended,  (the  “ACA”)  modified  the  intent  requirement  under  the  Anti-Kickback  Statute  to  a  stricter
standard, such that a person or entity no longer needs to have actual knowledge of the statute or specific intent to violate it
to have committed a violation. In addition, the ACA also provided that a violation of the federal Anti-Kickback Statute is
grounds for the government or a whistleblower to assert that a claim for payment of items or services resulting from such
violation constitutes a per se false or fraudulent claim for purposes of the federal civil False Claims Act. The Department
of Health and Human Services (“HHS”) recently promulgated a regulation with respect to the safe harbors that is effective
in  two  phases.  First,  the  regulation  excludes  from  the  definition  of  “remuneration”  limited  categories  of  (a)  Pharmacy
Benefit  Manager  (“PBM”)  rebates  or  other  reductions  in  price  to  a  plan  sponsor  under  Medicare  Part  D  or  a  Medicaid
Managed  Care  Organization  plan  reflected  in  point-of-sale  reductions  in  price  and  (b)  PBM  service  fees.  Second,  the
regulation expressly provides that rebates to plan sponsors under Medicare Part D either directly to the plan sponsor under
Medicare Part D, or indirectly through a pharmacy benefit manager will not be protected under the anti-kickback discount
safe  harbor.  Recent  legislation  delayed  implementation  of  this  portion  of  the  rule  until  January  1,  2026,  and  further
proposed legislation would permanently prohibit implementation of the rule beginning in 2026.

Table of Contents

The federal Civil False Claims Act prohibits any person from knowingly presenting, or causing to be presented, a
false or fraudulent claim for payment to, or approval by, the federal government, knowingly making, using, or causing to
be made or used a false record or statement material to a false or fraudulent claim to the federal government, or avoiding,
decreasing, or concealing an obligation to pay money to the federal government. A claim includes “any request or demand”
for money or property presented to the U.S. government. The civil False Claims Act has been used to assert liability on the
basis  of  kickbacks  and  other  improper  referrals,  improperly  reported  government  pricing  metrics  such  as  Best  Price  or
Average Manufacturer Price, improper use of Medicare provider or supplier numbers when detailing a provider of services,
improper  promotion  of  off-label  uses  not  expressly  approved  by  the  FDA  in  a  product’s  label,  and  allegations  as  to
misrepresentations with respect to products, contract requirements, and services rendered. In addition, private payers have
been filing follow-on lawsuits alleging fraudulent misrepresentation, although establishing liability and damages in these
cases  is  more  difficult  than  under  the  FCA.  Intent  to  deceive  is  not  required  to  establish  liability  under  the  civil  False
Claims Act. Rather, a claim may be false for deliberate ignorance of the truth or falsity of the information provided or for
acts in reckless disregard of the truth or falsity of that information. Civil False Claims Act actions may be brought by the
government  or  may  be  brought  by  private  individuals  on  behalf  of  the  government,  called  “qui  tam”  actions.  If  the
government decides to intervene in a qui tam action and prevails in the lawsuit, the individual will share in the proceeds
from any damages, penalties or settlement funds. If the government declines to intervene, the individual may pursue the
case  alone.  The  civil  FCA  provides  for  treble  damages  and  a  civil  penalty  for  each  false  claim,  such  as  an  invoice  or
pharmacy  claim  for  reimbursement,  which  can  aggregate  into  tens  and  even  hundreds  of  millions  of  dollars.  For  these
reasons,  since  2004,  False  Claims  Act  lawsuits  against  biopharmaceutical  companies  have  increased  significantly  in
volume and breadth, leading to several substantial civil and criminal settlements, as much as $3.0 billion, regarding certain
sales practices and promoting off label uses. Civil False Claims Act liability may further be imposed for known Medicare
or Medicaid overpayments, for example, overpayments caused by understated rebate amounts, that are not refunded within
60 days of discovering the overpayment, even if the overpayment was not caused by a false or fraudulent act. In addition,
conviction, or civil judgment for violating the FCA may result in exclusion from federal healthcare programs, suspension
and  debarment  from  government  procurement  and  non-procurement  programs,  and  refusal  of  orders  under  existing
government contracts. 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 payer.

The  government  may  further  prosecute  conduct  constituting  a  false  claim  under  the  criminal  False  Claims  Act.
The criminal False Claims Act prohibits the making or presenting of a claim to the government knowing such claim to be
false, fictitious, or fraudulent and, unlike the civil False Claims Act, requires proof of intent to submit a false claim.

The civil monetary penalties statute is another potential statute under which biopharmaceutical companies may be
subject to enforcement. Among other things, the civil monetary penalties statue imposes fines against any person who is
determined to have knowingly presented, or caused to be presented, claims to a federal healthcare program that the person
knows, or should know, is for an item or service that was not provided as claimed or is false or fraudulent.

Payment  or  reimbursement  of  prescription  therapeutics  by  Medicaid  or  Medicare  requires  sponsors  to  submit
certified pricing information to Centers of Medicare and Medicaid Services (“CMS”). The Medicaid Drug Rebate statute
requires sponsors to calculate and report price points, which are used to determine Medicaid manufacturer rebate payments
shared between the states and the federal government and Medicaid payment rates for certain therapeutics. For therapeutics
paid under Medicare Part B, sponsors must also calculate and report their Average Sales Price, which is used to determine
the  Medicare  Part  B  payment  rate.  In  addition,  therapeutics  covered  by  Medicaid  are  subject  to  an  additional  inflation
penalty  which  can  substantially  increase  rebate  payments.  For  certain  products,  including  those  approved  under  a  BLA
(including  biosimilars),  the  Veterans  Health  Care  Act  (the  “VHCA”)  requires  sponsors  to  calculate  and  report  to  the
Department of Veterans Affairs (“VA”) a different price called the Non-Federal Average Manufacturer Price, which is used
to determine the maximum price that can be charged to certain federal agencies, referred to as the Federal Ceiling Price
(“FCP”).  Like  the  Medicaid  rebate  amount,  the  FCP  includes  an  inflation  penalty.  A  Department  of  Defense  regulation
requires  sponsors  to  provide  this  discount  on  therapeutics  dispensed  by  retail  pharmacies  when  paid  by  the  TRICARE
Program.  All  these  price  reporting  requirements  create  risk  of  submitting  false  information  to  the  government,  potential
FCA liability and exclusion from certain of these programs.

35

Table of Contents

The  VHCA  also  requires  sponsors  of  covered  therapeutics  participating  in  the  Medicaid  program  to  enter  into
Federal Supply Schedule contracts with the VA through which their covered therapeutics must be sold to certain federal
agencies  at  FCP.  This  necessitates  compliance  with  applicable  federal  procurement  laws  and  regulations,  including
submission  of  commercial  sales  and  pricing  information,  and  subjects  companies  to  contractual  remedies  as  well  as
administrative, civil, and criminal sanctions. In addition, the VHCA requires sponsors participating in Medicaid to agree to
provide different mandatory discounts to certain Public Health Service grantees and other safety net hospitals and clinics
under  the  340B  program  based  on  the  sponsor’s  reported  Medicaid  pricing  information.  The  340B  program  has  its  own
regulatory  authority  to  impose  sanctions  for  non-compliance,  adjudicate  overcharge  claims  against  sponsors  by  the
purchasing entities, and impose civil monetary penalties for instances of overcharging.

The federal Health Insurance Portability and Accountability Act of 1996, (“HIPAA”), also created federal criminal
statutes  that  prohibit,  among  other  actions,  knowingly  and  willfully  executing,  or  attempting  to  execute,  a  scheme  to
defraud or to obtain, by means of false or fraudulent pretenses, representations or promises, any of the money or property
owned by, or under the custody or control of, a healthcare benefit program, regardless of whether the payor is public or
private, in connection with the delivery or payment for healthcare benefits, knowingly and willfully embezzling or stealing
from a healthcare benefit program, willfully obstructing a criminal investigation of a healthcare offense and knowingly and
willfully  falsifying,  concealing,  or  covering  up  by  any  trick  or  device  a  material  fact  or  making  any  materially  false
statements in connection with the delivery of, or payment for, healthcare benefits, items, or services relating to healthcare
matters. Additionally, the ACA amended the intent requirement of certain of these criminal statutes under HIPAA so that a
person  or  entity  no  longer  needs  to  have  actual  knowledge  of  the  statute,  or  the  specific  intent  to  violate  it,  to  have
committed a violation.

In  addition,  as  part  of  the  ACA,  the  federal  government  enacted  the  Physician  Payment  Sunshine  Act.
Manufacturers of drugs biologics and devices for which payment is available under Medicare, Medicaid, or the Children’s
Health  Insurance  Program  (with  certain  exceptions)  are  required  to  annually  report  to  CMS  certain  payments  and  other
transfers  of  value  made  to  or  at  the  request  of  covered  recipients,  which  are  physicians  (as  defined  under  the  Social
Security Act), physician assistants, nurse practitioners, clinical nurse specialists, certified registered nurse anesthetists and
certified  nurse  midwifes  licensed  in  the  U.S.  and  U.S.  teaching  hospitals,  as  well  as  ownership  and  investment  interests
held  by  physicians  and  their  immediate  family.  Payments  made  to  principal  investigators  and  research  institutions  at
teaching hospitals for clinical trials are also included within this law. Reported information is made publicly available by
CMS. Failure to submit required information may result in civil monetary penalties. If not preempted by this federal law,
several  states  currently  also  require  reporting  of  marketing  and  promotion  expenses,  as  well  as  gifts  and  payments  to
healthcare  professionals  and  organizations.  State  legislation  may  also  prohibit  gifts  and  various  other  marketing  related
activities  or  require  the  public  posting  of  information.  Certain  states  also  require  companies  to  implement  compliance
programs.

Further, we may be subject to data privacy and security regulation by both the federal government and the states in
which  we  conduct  our  business.  HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical
Health  Act,  (“HITECH  Act”),  and  their  respective  implementing  regulations  impose  certain  requirements  on  covered
entities  relating  to  the  privacy,  security,  and  transmission  of  protected  health  information.  Among  other  things,  the
HITECH Act, and its implementing regulations, made HIPAA’s security standards and certain privacy standards directly
applicable  to  “business  associates,”  defined  as  persons  or  organizations,  other  than  members  of  a  covered  entity’s
workforce,  that  create,  receive,  maintain,  or  transmit  protected  health  information  on  behalf  of  a  covered  entity  for  a
function or activity regulated by HIPAA. The HITECH Act also strengthened the civil and criminal penalties that may be
imposed against covered entities, business associates, and individuals, and gave state attorneys general new authority to file
civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys’ fees and
costs  associated  with  pursuing  federal  civil  actions.  In  addition,  other  federal  and  state  laws,  such  as  the  California
Consumer  Privacy  Act,  may  govern  the  privacy  and  security  of  health  and  other  information  in  certain  circumstances,
many of which differ from each other in significant ways, thus complicating compliance efforts.

Many states have also adopted laws similar to each of the above federal laws, which may be broader in scope and
apply  to  items  or  services  reimbursed  by  any  third-party  payor,  including  commercial  insurers.  Certain  state  laws  also
regulate sponsors’ use of prescriber-identifiable data. Certain states also require implementation of commercial compliance
programs  and  compliance  with  the  pharmaceutical  industry’s  voluntary  compliance  guidelines  and  the  applicable
compliance  guidance  promulgated  by  the  federal  government,  or  otherwise  restrict  payments  or  the  provision  of  other
items  of  value  that  may  be  made  to  healthcare  providers  and  other  potential  referral  sources;  impose  restrictions  on
marketing practices; or require sponsors to track and report information related to payments, gifts, and other items of value
to physicians and other healthcare providers. Recently, states have enacted or are considering legislation intended to make
drug prices more transparent and deter significant price increases that impose reporting requirements on biopharmaceutical
companies. These laws may affect our future sales, marketing, and other promotional activities by imposing administrative
and compliance burdens. Such laws also typically impose significant civil monetary penalties for each instance of reporting
noncompliance that can quickly aggregate into the millions of dollars.

If our operations are found to be in violation of any of the laws or regulations described above or any other laws
that  apply  to  us,  we  may  be  subject  to  penalties  or  other  enforcement  actions,  including  criminal  and  significant  civil
monetary  penalties,  damages,  fines,  disgorgement,  imprisonment,  exclusion  from  participation  in  government  healthcare
programs, corporate integrity agreements, suspension and debarment from government procurement and non-procurement
programs,  and  refusal  of  orders  under  existing  government  contracts,  reputational  harm,  diminished  profits  and  future
earnings, and the curtailment or restructuring of our operations, any of which could adversely affect our business.

U.S. Foreign Corrupt Practices Act

The  U.S.  Foreign  Corrupt  Practices  Act,  to  which  we  are  subject,  prohibits  corporations  and  individuals  from
engaging in certain activities to obtain or retain business or to influence a person working in an official capacity. It is illegal
to  pay,  offer  to  pay  or  authorize  the  payment  of  anything  of  value  to  any  foreign  government  official,  government  staff
member, political party, or political candidate in an attempt to obtain or retain business or to otherwise influence a person
working in an official capacity.

Coverage, Pricing and Reimbursement

The  containment  of  healthcare  costs  has  become  a  priority  of  federal,  state,  and  foreign  governments,  and  the
prices  of  drugs  have  been  a  focus  in  this  effort.  Third-party  payers  and  independent  non-profit  healthcare  research
organizations such as the Institute for Clinical and Economic Review are also increasingly challenging the prices charged
for medical products and services and examining the medical necessity, budget-impact, and cost-effectiveness of medical
products and services, in addition to their safety and efficacy. If these third-party payers do not consider a product to be
cost-effective  compared  to  other  available  therapies  and/or  the  standard  of  care,  they  may  not  cover  the  product  after
approval as a benefit under their plans or, if they do, measures including prior authorization and step-throughs could be
required, manufacturer rebates may be negotiated or required and/or the level of payment may not be sufficient to allow a
company  to  sell  its  products  at  a  profit.  The  U.S.  federal  and  state  governments  and  foreign  governments  have  shown
significant  interest  in  implementing  cost  containment  programs  to  limit  the  growth  of  government-paid  healthcare  costs,
including price controls, restrictions on coverage and reimbursement and requirements for substitution of generic products
for  branded  prescription  drugs.  In  this  regard,  for  example,  on  November  27,  2020,  CMS  issued  an  interim  final  rule
implementing a Most Favored Nation payment model under which reimbursement for certain Medicare Part B drugs and
biologicals will be based on a price that reflects the lowest per capital Gross Domestic Product-adjusted (“GDP-adjusted”)
price of any non-U.S. member country of the Organization for Economic Co-operation and Development (“OECD”) with a
GDP  per  capita  that  is  at  least  sixty  percent  of  the  U.S.  GDP  per  capita.  While  this  rule  now  has  been  rescinded,
government  negotiation  of  certain  Medicare  drug  pricing  continues  to  be  the  focus  of  recent  proposed  legislation.  The
Budget  Control  Act  of  2011,  among  other  things,  created  measures  for  spending  reductions  by  Congress.  Failure  of  the
Joint Select Committee on Deficit Reduction to reach required deficit reduction goals triggered the legislation’s automatic
reduction to several government programs. This includes aggregate reductions of Medicare payments to providers up to 2%
per  fiscal  year.  While  President  Biden  previously  signed  legislation  to  eliminate  this  reduction  through  the  end  of  2021,
recent  legislation  will  restart  the  reductions,  which  will  thereafter  remain  in  effect  through  2031  unless  additional
congressional action is taken. Adoption of additional healthcare reform controls and measures and tightening of restrictive
policies in jurisdictions with existing controls and measures, could limit payments for pharmaceuticals.

As a result, the marketability of any product which receives regulatory approval for commercial sale may suffer if
the  government  and  third-party  payers  choose  to  provide  low  coverage  and  reimbursement.  In  addition,  an  increasing
emphasis on managed care in the United States has increased and will continue to increase the pressure on drug pricing.
Decisions  regarding  whether  to  cover  any  of  our  products,  the  extent  of  coverage  and  amount  of  reimbursement  to  be
provided are made on a plan-by-plan basis. Further, no uniform policy for coverage and reimbursement exists in the United
States,  and  coverage  and  reimbursement  can  differ  significantly  from  payor  to  payor.  Coverage  policies,  third  party
reimbursement rates and drug pricing regulation may change at any time. In particular, the ACA contains provisions that
may  reduce  the  profitability  of  drug  products,  including,  for  example,  increased  rebates  for  drugs  sold  to  Medicaid
programs,  extension  of  Medicaid  rebates  to  Medicaid  managed  care  plans,  mandatory  discounts  for  certain  Medicare
Part  D  beneficiaries  and  annual  fees  based  on  pharmaceutical  companies’  share  of  sales  to  federal  healthcare  programs.
Multiple other current and proposed legislative and regulatory efforts require and likely will in the future require payment
of  increased  manufacturer  rebates  and  implement  mechanisms  to  reduce  drug  prices.  Even  if  favorable  coverage  and
reimbursement status is attained for one or more products that receive regulatory approval, less favorable coverage policies
and reimbursement rates may be implemented in the future.

Regulation in the European Union

Product  development,  the  regulatory  approval  process  and  safety  monitoring  of  medicinal  products  and  their
manufacturers in the European Union proceed broadly in the same way as they do in the United States. Therefore, many of
the  issues  discussed  above  apply  similarly  in  the  context  of  the  European  Union.  In  addition,  drugs  are  subject  to  the
extensive  price  and  reimbursement  regulations  of  the  various  EU  member  states.  The  Clinical  Trial  Regulation  EU
536/2014 (“CTR”), which replaced the current Clinical Trials Directive 2001/20/EC, as amended (“CTD”), on January 31,
2022,  provides  a  system  for  the  approval  of  clinical  trials  in  the  European  Union  via  (in  the  case  of  the  CTD)
implementation  through  national  legislation  of  the  member  states.  The  CTR  is  directly  applicable  in  all  member  states
without the need for national implementation. Whilst, for trials conducted in only one  country, approval has to be obtained
from the competent national authority of an EU member state in which the clinical trial is to be conducted before cross-
border trials within the EU, it is possible to make a single harmonized electronic submission and have a single assessment
process  for  clinical  trials  conducted  in  multiple  member  states.  Furthermore,  a  clinical  trial  may  only  be  started  after  a
competent  ethics  committee  has  issued  a  favorable  opinion  on  the  clinical  trial  application  (“CTA”),  which  must  be
supported  by  an  investigational  medicinal  product  dossier  with  supporting  information  prescribed  by  the  CTD  and
corresponding  national  laws  of  the  member  states  and  further  detailed  in  applicable  guidance  documents.  In  the  case  of
Advanced  Therapy  Investigational  Medical  Products  (“ATIMPs”)  consisting  of  or  containing  Genetically  Modified
Organisms  (“GMOs”),  as  is  the  case  for  uniQure’s  products,  an  additional  approval  for  the  environmental  and  biosafety
aspects of the use and release of the GMO is required by the GMO competent authorities and GMO directives have been
implemented  in  different  ways  by  Member  States;  either  following  the  directive  for  “Contained  use”  (Directive
2009/41/EC) or “deliberate release” (Directive 2001/18/EC). This results in some EU member states, the GMO application
must be approved before the Clinical Trial Application (CTA) is submitted, in some after approval of the CTA and in some
parallel.

The sponsor of a clinical trial, or its legal representative, must be based in the European Economic Area (“EEA”).
European regulators and ethics committees also require the submission of adverse event reports during a study and a copy
of the final study report. Under the CTR, member states may dispense with the requirement for a legal representative for a
non-EU resident sponsor provided there is a contact person based in the EEA.

Under  the  CTR,  the  introduction  of  a  new  databased  called  the  Clinical  Trial  Information  System  (“CTIS”),
requires sponsors to upload and submit all data, including initial clinical trial application data and documentation, to the
CTIS,  with  such  data  being  publicly  available,  with  few  exceptions.  This  means  data  transparency  throughout  the
development process with the onus on sponsors to protect patient confidentiality at the point of submission.

Marketing approval

Marketing  approvals  under  the  European  Union  regulatory  system  may  be  obtained  through  a  centralized  or
decentralized procedure. The centralized procedure results in the grant of a single marketing authorization that is valid for
all—currently 28—EU member states. Pursuant to Regulation (EC) No 726/2004, as amended, the centralized procedure is
mandatory  for  drugs  developed  by  means  of  specified  biotechnological  processes,  and  advanced  therapy  medicinal
products  as  defined  in  Regulation  (EC)  No  1394/2007,  as  amended.  Drugs  for  human  use  containing  a  new  active
substance for which the therapeutic indication is the treatment of specified diseases, including but not limited to acquired
immune deficiency syndrome, neurodegenerative disorders, auto-immune diseases and other immune dysfunctions, as well
as drugs designated as orphan drugs pursuant to Regulation (EC) No 141/2000, as amended, also fall within the mandatory
scope  of  the  centralized  procedure.  Because  of  our  focus  on  gene  therapies,  which  fall  within  the  category  of  advanced
therapy  medicinal  products  (“ATMPs”)  and  orphan  indications,  our  products  and  product  candidates  will  need  to  go
through the centralized procedure.

In the MAA the applicant must properly and sufficiently demonstrate the quality, safety, and efficacy of the drug.
Guidance on the factors that the EMA will consider in relation to the development and evaluation of ATMPs have been
issued  and  include,  among  other  things,  the  preclinical  studies  required  to  characterize  ATMPs;  the  manufacturing  and
control  information  that  should  be  submitted  in  a  MAA;  and  post-approval  measures  required  to  monitor  patients  and
evaluate  the  long-term  efficacy  and  potential  adverse  reactions  of  ATMPs.  Although  these  guidelines  are  not  legally
binding, we believe that our compliance will effectively be necessary to gain and maintain approval for any of our product
candidates.  The  maximum  timeframe  for  the  evaluation  of  an  MAA  under  the  centralized  procedure  is  210  days  after
receipt of a valid application subject to clock stops during which the applicant deals with EMA questions.

Market access can be expedited through the grant of conditional authorization for a medicine that may fulfil unmet
needs which may be granted provided that the benefit-risk balance of the product is positive. The benefit-risk balance is
likely  to  be  positive  if  the  applicant  can  provide  comprehensive  data  and  the  benefit  to  public  health  of  the  medicinal
product's  immediate  availability  on  the  market  outweighs  the  risks  due  to  need  for  further  data.  Such  authorizations  are
valid for one year and can be renewed annually. The holder will be required to complete specific obligations (ongoing or
new  studies,  and  in  some  cases  additional  activities)  with  a  view  to  providing  comprehensive  data  confirming  that  the
benefit-risk balance is positive. Once comprehensive data on the product have been obtained, the marketing authorization
may be converted into a standard marketing authorization (not subject to specific obligations). Initially, this is valid for 5
years, but can be renewed for unlimited validity. Applicants for conditional authorizations can benefit from early dialogue
with  EMA  through  scientific  advice  or  protocol  assistance  and  discuss  their  development  plan  well  in  advance  of  the
submission of a marketing-authorization application. Other stakeholders (e.g., health technology assessment bodies) can be
included.

In addition, the priority medicines (PRIME) scheme for medicines that may offer a major therapeutic advantage
over existing treatments, or benefit patients without treatment options based on early clinical data, is intended to support
the development of medicines that target an unmet medical need. This voluntary scheme is based on enhanced interaction
and  early  dialogue  with  developers  of  promising  medicines,  to  optimize  development  plans  and  speed  up  evaluation  so
these medicines can reach patients earlier. Early dialogue and scientific advice also ensure that patients only participate in
trials designed to provide the data necessary for an application, making the best use of limited resources.

39

The  European  Union  also  provides  for  a  system  of  regulatory  data  and  market  exclusivity.  According  to
Article 14(11) of Regulation (EC) No 726/2004, as amended, and Article 10 of Directive 2001/83/EC, as amended, upon
receiving  marketing  authorization,  new  chemical  entities  approved  on  the  basis  of  complete  independent  data  package
benefit from eight years of data exclusivity and an additional two years of market exclusivity. Data exclusivity prevents
regulatory  authorities  in  the  European  Union  from  referencing  the  innovator’s  data  to  assess  a  generic  (abbreviated)
application  during  the  eight-year  period  from  when  the  first  placement  of  the  product  on  the  EEA  market.  During  the
additional two-year period of market exclusivity, a generic marketing authorization can be submitted, and the innovator’s
data may be referenced, but no generic medicinal product can be marketed until the expiration of the market exclusivity.
The  overall  ten-year  period  will  be  extended  to  a  maximum  of  eleven  years  if,  during  the  first  eight  years  of  those  ten
years,  the  marketing  authorization  holder  obtains  an  authorization  for  one  or  more  new  therapeutic  indications  which,
during  the  scientific  evaluation  prior  to  their  authorization,  are  held  to  bring  a  significant  clinical  benefit  in  comparison
with existing therapies. Even if a compound is considered to be a new chemical entity and the innovator can gain the period
of data exclusivity, another company nevertheless could also market another version of the drug if such company obtained
marketing authorization based on an MAA with a complete independent data package of pharmaceutical test, preclinical
tests, and clinical trials. The EMA has also issued guidelines for a comprehensive comparability exercise for biosimilars,
and for specific classes of biological products.

Under  Regulation  (EC)  No  141/2000  article  3  as  amended  (Orphan  Drug  Regulation,  (“ODR”))  a  product  can
benefit  from  orphan  drug  status  if  it  is  intended  for  the  diagnosis,  prevention,  or  treatment  of  a  life-threatening  or
chronically debilitating condition affecting not more than five in 10,000 people in the European Community (EC) when the
application is made. The principal benefit of such status is 10 years’ market exclusivity once they are approved preventing
the  subsequent  approval  of  similar  medicines  with  similar  indications  although  this  may  be  reduced  to  six  years  under
certain circumstances including if the product is sufficiently profitable not to justify maintenance of market exclusivity.

Additional rules apply to medicinal products for pediatric use under Regulation (EC) No 1901/2006, as amended.
Potential  incentives  include  a  six-month  extension  of  any  supplementary  protection  certificate  granted  pursuant  to
Regulation (EC) No 469/2009, however not in cases in which the relevant product is designated as an orphan medicinal
product pursuant to the ODR. Instead, medicinal products designated as orphan medicinal product may enjoy an extension
of the ten-year market exclusivity period granted under Regulation (EC) No 141/2000, as amended, to twelve years subject
to the conditions applicable to orphan drugs.

Manufacturing and promotion

Pursuant  to  Commission  Directive  2003/94/EC  as  transposed  into  the  national  laws  of  the  member  states,  the
manufacturing of investigational medicinal products and approved drugs is subject to a separate manufacturer’s license and
must be conducted in strict compliance with cGMP requirements, which mandate the methods, facilities, and controls used
in manufacturing, processing, and packing of drugs to assure their safety and identity. Manufacturers must have at least one
qualified  person  permanently  and  continuously  at  their  disposal.  The  qualified  person  is  ultimately  responsible  for
certifying that each batch of finished product released onto the market has been manufactured in accordance with cGMP
and  the  specifications  set  out  in  the  marketing  authorization  or  investigational  medicinal  product  dossier.  cGMP
requirements are enforced through mandatory registration of facilities and inspections of those facilities. Failure to comply
with these requirements could interrupt supply and result in delays, unanticipated costs, and lost revenues, and subject the
applicant to potential legal or regulatory action, including but not limited to warning letters, suspension of manufacturing,
seizure of product, injunctive action, or possible civil and criminal penalties.

Advertising

In  the  European  Union,  the  promotion  of  prescription  medicines  is  subject  to  intense  regulation  and  control,
including a prohibition on direct-to-consumer advertising. All medicines advertising must be consistent with the product’s
approved  summary  of  products  characteristics,  factual,  accurate,  balanced  and  not  misleading.  Advertising  of  medicines
pre-approval or off-label is prohibited. Some jurisdictions require that all promotional materials for prescription medicines
be subjected to either prior internal or regulatory review & approval.

40

Table of Contents

Other Regulatory Requirements

A holder of a marketing authorization for a medicinal product is legally obliged to fulfill several obligations by
virtue of its status as a marketing authorization holder (“MAH”). The MAH can delegate the performance of related tasks
to third parties, such as distributors or marketing collaborators, provided that this delegation is appropriately documented
and the MAH maintains legal responsibility and liability.

The obligations of an MAH include:

● Manufacturing and Batch Release. MAHs should guarantee that all manufacturing operations comply with
relevant laws and regulations, applicable good manufacturing practices, with the product specifications and
manufacturing conditions set out in the marketing authorization and that each batch of product is subject to
appropriate release formalities.

● Pharmacovigilance. MAHs  are  obliged  to  establish  and  maintain  a  pharmacovigilance  system,  including  a
qualified  person  responsible  for  oversight,  to  submit  safety  reports  to  the  regulators  and  comply  with  the
good pharmacovigilance practice guidelines adopted by the EMA.

● Advertising and Promotion. MAHs  remain  responsible  for  all  advertising  and  promotion  of  their  products,
including promotional activities by other companies or individuals on their behalf and in some cases, must
conduct internal or regulatory pre-approval of promotional materials.

● Medical Affairs/Scientific Service. MAHs are required to disseminate scientific and medical information on

their medicinal products to healthcare professionals, regulators, and patients.

● Legal  Representation  and  Distributor  Issues.  MAHs  are  responsible  for  regulatory  actions  or  inactions  of

their distributors and agents.

● Preparation,  Filing  and  Maintenance  of  the  Application  and  Subsequent  Marketing  Authorization.  MAHs
must  maintain  appropriate  records,  comply  with  the  marketing  authorization’s  terms  and  conditions,  fulfill
reporting obligations to regulators, submit renewal applications and pay all appropriate fees to the authorities.

We may hold any future marketing authorizations granted for our product candidates in our own name or appoint
an affiliate or a collaborator to hold marketing authorizations on our behalf. Any failure by an MAH to comply with these
obligations  may  result  in  regulatory  action  against  an  MAH  and  ultimately  threaten  our  ability  to  commercialize  our
products.

Reimbursement

In  the  European  Union,  the  pricing  and  reimbursement  mechanisms  by  private  and  public  health  insurers  vary
largely  by  country  and  even  within  countries.  In  respect  of  the  public  systems,  reimbursement  for  standard  drugs  is
determined  by  guidelines  established  by  the  legislature  or  responsible  national  authority.  Some  jurisdictions  operate
positive  and  negative  list  systems  under  which  products  may  only  be  marketed  once  a  reimbursement  price  has  been
agreed. Other member states allow companies to determine the prices for their medicines but monitor and control company
profits and may limit or restrict reimbursement and can include retrospective rebates to the Government. The downward
pressure on healthcare costs in general, particularly prescription drugs, has become very intense. As a result, increasingly
high barriers are being erected to the entry of new products and some of EU countries require the completion of studies that
compare the cost-effectiveness of a particular product candidate to currently available therapies to obtain reimbursement or
pricing approval. Special pricing and reimbursement rules may apply to orphan drugs.

Inclusion of orphan drugs in reimbursement systems tend to focus on the medical usefulness, need, quality and
economic  benefits  to  patients  and  the  healthcare  system  as  for  any  drug.  Acceptance  of  any  medicinal  product  for
reimbursement  may  come  with  cost,  use  and  often  volume  restrictions,  which  again  can  vary  by  country.  In  addition,
results-based  rules  or  agreements  on  reimbursement  may  apply.  Recently,  a  process  has  been  formalized  that  allows
sponsors  to  receive  parallel  advice  from  EMA  and  relevant  national  health  technology  assessment  (“HTA”)  bodies  for
pivotal clinical studies designed to support marketing approval. This process was followed for etranacogene dezaparvovec.

41

Table of Contents

Orphan Drug Regulation

We have been granted orphan drug exclusivity for etranacogene dezaparvovec for the treatment of hemophilia B
as  well  as  for  AMT-130  for  the  treatment  of  Huntington’s  disease  subject  to  the  conditions  applicable  to  orphan  drug
exclusivity in the European Union. Regulation (EC) No 141/2000, as amended, states that a drug will be designated as an
orphan drug if its sponsor can establish:

● that it is intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating
condition  affecting  not  more  than  five  in  ten  thousand  persons  in  the  Community  when  the  application  is
made,  or  that  it  is  intended  for  the  diagnosis,  prevention  or  treatment  of  a  life-threatening,  seriously
debilitating or serious and chronic condition in the European Union and that without incentives it is unlikely
that the marketing of the drug in the European Union would generate sufficient return to justify the necessary
investment; and

● that there exists no satisfactory method of diagnosis, prevention, or treatment of the condition in question that
has  been  authorized  in  the  European  Union  or,  if  such  method  exists,  that  the  drug  will  be  of  significant
benefit to those affected by that condition.

Regulation (EC) No 847/2000 sets out further provisions for implementation of the criteria for designation of a
drug as an orphan drug. An application for the designation of a drug as an orphan drug must be submitted at any stage of
development of the drug before filing of a marketing authorization application.

If an EU-wide community marketing authorization in respect of an orphan drug is granted pursuant to Regulation
(EC)  No  726/2004,  as  amended,  the  European  Union  and  the  member  states  will  not,  for  a  period  of  10  years,  accept
another application for a marketing authorization, or grant a marketing authorization or accept an application to extend an
existing marketing authorization, for the same therapeutic indication, in respect of a similar drug.

This period may however be reduced to six years if, at the end of the fifth year, it is established, in respect of the
drug concerned, that the criteria for orphan drug designation are no longer met, in other words, when it is shown on the
basis  of  available  evidence  that  the  product  is  sufficiently  profitable  not  to  justify  maintenance  of  market  exclusivity.
Notwithstanding the foregoing, a marketing authorization may be granted, for the same therapeutic indication, to a similar
drug if:

● the  holder  of  the  marketing  authorization  for  the  original  orphan  drug  has  given  its  consent  to  the  second

applicant;

● the holder of the marketing authorization for the original orphan drug is unable to supply sufficient quantities

of the drug; or

● the second applicant can establish in the application that the second drug, although similar to the orphan drug

already authorized, is safer, more effective, or otherwise clinically superior.

Regulation (EC) No 847/2000 lays down definitions of the concepts similar drug and clinical superiority, which
concepts have been expanded upon in subsequent Commission guidance. Other incentives available to orphan drugs in the
European  Union  include  financial  incentives  such  as  a  reduction  of  fees  or  fee  waivers  and  protocol  assistance.  Orphan
drug designation does not shorten the duration of the regulatory review and approval process.

Human Capital Resources

As of December 31, 2021, we had a total of 463 employees, 250 of whom are based in The Netherlands, 206 in
the United States of America, and seven in other European countries. As of December 31, 2021, 142 of our employees had
an M.D. or Ph.D. degree, or the foreign equivalent. During 2017, we established a works council in the Netherlands. None
of  our  employees  are  subject  to  collective  bargaining  agreements  or  other  labor  organizations.  We  believe  that  we  have
good relations with all our employees and with the works council in the Netherlands.

Our values are to:
● Be passionate about the patient;
● Act with integrity and respect;
● Take ownership and act with urgency;
● Collaborate for success;
● Innovate every day; and
● Focus relentlessly on quality.

Development  of  our  culture  is  reflected  as  part  of  our  annual  corporate  goals.  We  invest  in  numerous  learning
opportunities focused on individual, management and team development and other initiatives to support our employees and
build  our  culture.  In  2021  we  initiated  activities  to  coordinate  our  various  ongoing  activities  and  initiatives  within  an
environmental, social and governance (“ESG”) framework.

Corporate Information

uniQure B.V. (the “Company”) was incorporated on January 9, 2012 as a private company with limited liability
(besloten vennootschap met beperkte aansprakelijkheid) under the laws of the Netherlands. We are a leader in the field of
gene  therapy  and  seek  to  deliver  to  patients  suffering  from  rare  and  other  devastating  diseases  single  treatments  with
potentially curative results. Our business was founded in 1998 and was initially operated through our predecessor company,
Amsterdam Molecular Therapeutics Holding N.V (“AMT”). In 2012, AMT undertook a corporate reorganization, pursuant
to which uniQure B.V. acquired the entire business and assets of AMT and completed a share-for-share exchange with the
shareholders  of  AMT.  Effective  February  10,  2014,  in  connection  with  the  initial  public  offering,  we  converted  into  a
public company with limited liability (naamloze vennootschap) and changed its legal name from uniQure B.V. to uniQure
N.V.

We  are  registered  in  the  trade  register  of  the  Dutch  Chamber  of  Commerce  (Kamer  van  Koophandel)  under
number  54385229.  Our  headquarters  are  in  Amsterdam,  the  Netherlands,  and  its  registered  office  is  located  at
Paasheuvelweg 25, Amsterdam 1105 BP, the Netherlands and its telephone number is +31 20 240 6000.

From our initial public offering until December 31, 2018, we were an emerging growth company, as defined in the
Jumpstart  Our  Business  Startups  Act  of  2012.  On  the  last  business  day  of  our  second  quarter  in  fiscal  year  2018  the
aggregate worldwide market value of ordinary shares held by our non-affiliate shareholders exceeded $700.0 million. As a
result, as of December 31, 2018, we were considered a large accelerated filer and as a consequence lost our status as an

Item 1A.  Risk Factors

An investment in our ordinary shares involves a high degree of risk. You should carefully consider the following
information about these risks, together with the other information appearing elsewhere in this Annual Report on Form 10-
K,  including  our  financial  statements  and  related  notes  thereto,  before  deciding  to  invest  in  our  ordinary  shares.  We
operate  in  a  dynamic  and  rapidly  changing  industry  that  involves  numerous  risks  and  uncertainties.  The  risks  and
uncertainties described below are not the only ones we face. Other risks and uncertainties, including those that we do not
currently  consider  material,  may  impair  our  business.  If  any  of  the  risks  discussed  below  actually  occur,  our  business,
financial condition, operating results, or cash flows could be materially adversely affected. This could cause the value of
our securities to decline, and you may lose all or part of your investment.

Risks Related to the Current Covid Pandemic

Our business, operations, human resources and supply chain have been, and may continue to be, materially

and adversely affected by the ongoing Covid pandemic.

On  March  11,  2020,  the  WHO  declared  the  ongoing  outbreak  of  Covid  a  pandemic.  The  Covid  pandemic  is
affecting the United States and global economies and has affected and may continue to affect our operations and those of
third parties on which we rely. The Covid pandemic has caused and may continue to cause disruptions in our raw material
supply,  our  commercial-scale  manufacturing  capabilities  for  AAV-based  gene  therapies,  the  development  of  our  product
candidates, employee productivity and the conduct of current and future clinical trials. In addition, the Covid pandemic has
affected and may continue to affect the operations of the FDA, EMA, and other health authorities, which could result in
delays of reviews and approvals, including with respect to our product candidates.

As evidenced by the postponement of procedures for two patients in our Phase I/II clinical study of AMT-130, the
evolving  Covid  pandemic  has  impacted  the  pace  of  enrollment  and  procedures  in  our  clinical  trials,  as  well  as  caused
challenges in scheduling follow-up visits and managing other aspects of our clinical trials. We may in the future be affected
by similar delays as patients may avoid or may not be able to travel to healthcare facilities and physicians’ offices unless
due to a health emergency and clinical trial staff may no longer be able to get to the clinic due to restrictions or illness.
Such  facilities  and  offices  have  been  and  may  continue  to  be  required  to  focus  limited  resources  on  non-clinical  trial
matters, including treatment of Covid patients, thereby decreasing availability, in whole or in part, for clinical trial services.
In addition, employee disruptions and remote working environments related to the Covid pandemic, and federal, state, and
local public health measures designed to mitigate the spread of the virus, have impacted, and could continue to negatively
impact  the  efficiency  and  pace  with  which  we  work  and  develop  our  product  candidates  and  our  manufacturing
capabilities. Further, while the potential economic impact brought by, and the duration of, the Covid pandemic is difficult
to assess or predict, the impact of the Covid pandemic on global financial markets may reduce our ability to access capital,
which could negatively impact our long-term liquidity. The ultimate impact of the Covid pandemic is highly uncertain and
subject to change. We do not yet know the full extent of potential delays or impacts on our business, financing, or clinical
trial activities or on healthcare systems or the global economy as a whole. However, these negative effects could have a
material impact on our liquidity, capital resources, operations, and business and those of the third parties on whom we rely.

Global supply chains have been disrupted, causing shortages, which could further impact our clinical trials. This
disruption  of  our  employees,  distributors  and  suppliers  has  historically  impacted  and  may  continue  to  impact  our  future
operating  results.  Additionally,  to  the  extent  that  inspections  of  facilities  by  governmental  authorities  are  required,  the
review of our marketing applications or supplements may further be delayed as regulatory authorities, such as FDA, have
significantly limited facility inspections during the pandemic.

We  may  also  be  subject  to  further  laws,  regulations,  guidelines,  executive  orders  and  other  requirements  at  the
federal,  state  and  local  levels  related  to  the  pandemic,  which  we  may  be  required  to  undertake  or  that  we  choose  to
undertake. Any such requirements or guidelines that we adopt could have a material impact on our business operations.

Risks Related to the Development of Our Product Candidates

None of our product candidates have been approved for commercial sale and they might never receive

regulatory approval or become commercially viable. We have never generated any significant revenue from product
sales and may never be profitable.

All of our product candidates are in research or development. We have not generated any revenues from the sale
of products or manufacturing of a product for a third party and do not expect to generate any such revenue before 2022, at
the  earliest.  Our  product  candidates  including  AMT-130  and  any  of  our  other  potential  product  candidates  will  require
extensive  preclinical  and/or  clinical  testing,  manufacture  development  and  regulatory  approval  prior  to  commercial  use.
Our  research  and  development  efforts  may  not  be  successful.  Even  if  our  clinical  development  efforts  result  in  positive
data, our product candidates may not receive regulatory approval or be successfully introduced and marketed at prices that
would permit us to operate profitably.

We have encountered and may encounter future delays in and impediments to the progress of our clinical trials

or fail to demonstrate the safety and efficacy of our product candidates.

Clinical  and  non-clinical  development  is  expensive,  time-consuming,  and  uncertain  as  to  outcome.  Our  product
candidates are in different stages of clinical or preclinical development, and there is a significant risk of failure or delay in
each  of  these  programs.  For  example,  we  experienced  an  immaterial  but  unexpected  delay  when  our  clinical  trials  of
etranacogene  dezaparvovec  were  placed  on  clinical  hold  by  the  FDA  from  December  2020  to  April  2021,  following  a
preliminary diagnosis of hepatocellular carcinoma in one patient. We cannot guarantee that any preclinical tests or clinical
trials will be completed as planned or completed on schedule, if at all. A failure of one or more preclinical tests or clinical
trials can occur at any stage of testing. Events that may prevent successful or timely completion of clinical development, as
well as product candidate approval, include, but are not limited to:

● occurrence  of  serious  adverse  events  associated  with  a  product  candidate  that  are  viewed  to  outweigh  its

potential benefits;

● delays in reaching a consensus with regulatory agencies on study design;
● delays in reaching agreement on acceptable terms with prospective clinical research organizations (“CROs”) and

clinical trial sites;

● delays in receiving regulatory authorization to conduct the clinical trials or a regulatory authority decision that

the clinical trial should not proceed;

● delays in obtaining or failure to obtain required IRB and IBC approval at each clinical trial site;
● requirements of regulatory authorities, IRBs, or IBCs to modify a study in such a way that it makes the study

impracticable to conduct;

● regulatory authority requirements to perform additional or unanticipated clinical trials;
● changes in standards of care which may necessitate the modification of our clinical trials or the conduct of new

trials;

● regulatory authority refusal to accept data from foreign clinical study sites;
● disagreements with regulatory authorities regarding our study design, including endpoints, our chosen indication,
or  our  interpretation  of  data  from  preclinical  studies  and  clinical  trials  or  a  finding  that  a  product  candidate’s
benefits do not outweigh its safety risks;

● recommendations from DSMBs to discontinue, pause, or modify the trial;
● imposition  of  a  clinical  hold  by  regulatory  agencies  after  an  inspection  of  our  clinical  trial  operations  or  trial

sites;

● suspension  or  termination  of  clinical  research  for  various  reasons,  including  noncompliance  with  regulatory
requirements or a finding that the participants are being exposed to unacceptable health risks, undesirable side
effects,  or  other  unexpected  characteristics  (alone  or  in  combination  with  other  products)  of  the  product
candidate, or due to findings of undesirable effects caused by a chemically or mechanistically similar therapeutic
or therapeutic candidate;

● failure by CROs, other third parties or us to adhere to clinical trial requirements or otherwise properly manage
the clinical trial process, including meeting applicable timelines, properly documenting case files, including the
retention of proper case files, and properly monitoring and auditing clinical sites;

● failure  of  sites  or  clinical  investigators  to  perform  in  accordance  with  Good  Clinical  Practice  or  applicable

regulatory guidelines in other countries;

● failure of patients to abide by clinical trial requirements;

45

Table of Contents

● difficulty or delays in patient recruiting into clinical trials or in the addition of new investigators;
● the impact of the COVID-19 pandemic on the healthcare system or any clinical trial sites;
● delays  or  deviations  in  the  testing,  validation,  manufacturing,  and  delivery  of  our  product  candidates  to  the

clinical sites;

● delays in having patients complete participation in a study or return for post-treatment follow-up;
● clinical trial sites or patients dropping out of a study;
● the number of patients required for clinical trials of our product candidates being larger than we anticipate;
● clinical  trials  producing  negative  or  inconclusive  results,  or  our  studies  failing  to  reach  the  necessary  level  of
statistical  significance,  requiring  that  we  conduct  additional  clinical  trials  or  abandon  product  development
programs;

● interruptions  in  manufacturing  clinical  supply  of  our  product  candidates  or  issues  with  manufacturing  product

candidates that meet the necessary quality requirements;

● unanticipated clinical trial costs or insufficient funding, including to pay substantial application user fees;
● occurrence of serious adverse events or other undesirable side effects associated with a product candidate that are

viewed to outweigh its potential benefits;

● disagreements with regulatory authorities regarding the interpretation of our clinical trial data and results, or the

emergence of new information about or impacting our product candidates;
● determinations that there are issues with our manufacturing facility or process; or
● changes  in  regulatory  requirements  and  guidance,  as  well  as  new,  revised,  postponed,  or  frozen  regulatory
requirements (such as the forthcoming EU Clinical Trials Regulation), that require amending or submitting new
clinical protocols, undertaking additional new tests or analyses, or submitting new types or amounts of clinical
data.

Before obtaining marketing approval from regulatory authorities for the sale of our product candidates, we must
conduct extensive clinical trials to demonstrate the safety and efficacy of the product candidates in humans. Such trials and
regulatory  review  and  approval  take  many  years.  It  is  impossible  to  predict  when  or  if  any  of  our  clinical  trials  will
demonstrate that product candidates are effective or safe in humans.

If the results of our clinical trials are inconclusive, or fail to meet the level of statistical significance required for

approval or if there are safety concerns or adverse events associated with our product candidates, we may:

● be delayed in or altogether prevented from obtaining marketing approval for our product candidates;
● obtain approval for indications or patient populations that are not as broad as intended or desired;
● obtain approval with labeling that includes significant use or distribution restrictions or safety warnings;
● be subject to changes with the way the product is administered;
● be  required  to  perform  additional  clinical  trials  to  support  approval  or  be  subject  to  additional  post-marketing

testing requirements;

● have regulatory authorities withdraw their approval of the product or impose restrictions on its distribution in the

form of a modified risk evaluation and mitigation strategy;

● be subject to the addition of labeling statements, such as warnings or contraindications;
● be sued; or
● experience damage to our reputation.

Because of the nature of the gene therapies we are developing, regulators may also require us to demonstrate long-
term gene expression, clinical efficacy and safety, which may require additional or longer clinical trials, and which may not
be able to be demonstrated to the regulatory authorities’ standards.

Our ability to recruit patients for our trials is often reliant on third parties, such as clinical trial sites. Clinical trial
sites may not have the adequate infrastructure established to handle gene therapy products or may have difficulty finding
eligible patients to enroll into a trial.

46

Table of Contents

In addition, we, or any collaborators we may have may not be able to locate and enroll enough eligible patients to
participate in these trials as required by the FDA, the EMA or similar regulatory authorities outside the United States and
the European Union. This may result in our failure to initiate or continue clinical trials for our product candidates or may
cause us to abandon one or more clinical trials altogether. Because our programs are focused on the treatment of patients
with rare or orphan or ultra-orphan diseases, our ability to enroll eligible patients in these trials may be limited or slower
than  we  anticipate  considering  the  small  patient  populations  involved  and  the  specific  age  range  required  for  treatment
eligibility  in  some  indications.  In  addition,  our  potential  competitors,  including  major  pharmaceutical,  specialty
pharmaceutical  and  biotechnology  companies,  academic  institutions  and  governmental  agencies  and  public  and  private
research institutions, may seek to develop competing therapies, which would further limit the small patient pool available
for our studies. Also, patients may be reluctant to enroll in gene therapy trials where there are other therapeutic alternatives
available  or  that  may  become  available,  which  may  be  for  various  reasons  including  uncertainty  about  the  safety  or
effectiveness of a new therapeutic such as a gene therapy and the possibility that treatment with a gene therapy therapeutic
could  preclude  future  gene  therapy  treatments  due  to  the  formation  of  antibodies  following  and  in  response  to  the
treatment.

Any inability to successfully initiate or complete preclinical and clinical development could result in additional
costs to us or impair our ability to receive marketing approval, to generate revenues from product sales or obtain regulatory
and  commercialization  milestones  and  royalties.  In  addition,  if  we  make  manufacturing  or  formulation  changes  to  our
product  candidates,  including  changes  in  the  vector  or  manufacturing  process  used,  we  may  need  to  conduct  additional
studies  to  bridge  our  modified  product  candidates  to  earlier  versions.  It  is  also  possible  that  any  such  manufacturing  or
formulation changes may have an adverse impact on the performance of the product candidate. Clinical trial delays could
also shorten any periods during which we may have the exclusive right to commercialize our product candidates or allow
our competitors to bring products to market before we do, which could impair our ability to successfully commercialize our
product candidates and may materially harm our business, financial condition, and results of operations.

Our  progress  in  early-stage  clinical  trials  may  not  be  indicative  of  long-term  efficacy  in  late-stage  clinical
trials, and our progress in trials for one product candidate may not be indicative of progress in trials for other product
candidates.

Study designs and results from previous studies are not necessarily predictive of our future clinical study designs
or results, and initial, top-line, or interim results may not be confirmed upon full analysis of the complete study data. Our
product candidates may fail to show the required level of safety and efficacy in later stages of clinical development despite
having  successfully  advanced  through  initial  clinical  studies.  Changes  to  product  candidates  may  also  impact  their
performance in subsequent studies.

A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in
later-stage  clinical  trials  even  after  achieving  promising  results  in  early-stage  clinical  trials.  If  a  larger  population  of
patients does not experience positive results during clinical trials, if these results are not reproducible or if our products
show  diminishing  activity  over  time,  our  product  candidates  may  not  receive  approval  from  the  FDA  or  EMA.  Data
obtained from preclinical and clinical activities are subject to varying interpretations, which may delay, limit, or prevent
regulatory  approval.  In  addition,  we  may  encounter  regulatory  delays  or  rejections  because  of  many  factors,  including
changes in regulatory policy during the period of product development. Failure to confirm favorable results from earlier
trials  by  demonstrating  the  safety  and  effectiveness  of  our  products  in  later-stage  clinical  trials  with  larger  patient
populations could have a material adverse effect on our business, financial condition, and results of operations.

Fast track product, breakthrough therapy, priority review, or RMAT designation by the FDA, or access to the
PRIME  scheme  by  the  EMA,  for  our  product  candidates  may  not  lead  to  faster  development  or  regulatory  review  or
approval process, and it does not increase the likelihood that our product candidates will receive marketing approval.

We  have  obtained  and  may  in  the  future  seek  one  or  more  of  fast  track  designation,  breakthrough  therapy
designation, RMAT designation, PRIME scheme access or priority review designation for our product candidates. A fast
track product designation is designed to facilitate the clinical development and expedite the review of drugs intended to
treat  a  serious  or  life-threatening  condition  and  which  demonstrate  the  potential  to  address  an  unmet  medical  need.  A
breakthrough therapy is defined as a drug that is intended, alone or in combination with one or more other drugs, to treat a
serious  or  life-threatening  disease  or  condition,  where  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.  A  RMAT  designation  is  designed  to  accelerate
approval  for  regenerative  advanced  therapies.  Priority  review  designation  is  intended  to  speed  the  FDA  marketing
application  review  timeframe  for  drugs  that  treat  a  serious  condition  and,  if  approved,  would  provide  a  significant
improvement  in  safety  or  effectiveness.  PRIME  is  a  scheme  provided  by  the  EMA,  similar  to  the  FDA’s  breakthrough
therapy designation, to enhance support for the development of medicines that target an unmet medical need.

47

Table of Contents

For  drugs  and  biologics  that  have  been  designated  as  fast  track  products,  RMAT,  or  breakthrough  therapies,  or
granted access to the PRIME scheme, interaction and communication between the regulatory agency and the sponsor of the
trial can help to identify the most efficient path for clinical development. Sponsors of fast track products, RMAT products,
or breakthrough therapies may also be able to submit marketing applications on a rolling basis, meaning that the FDA may
review portions of a marketing application before the sponsor submits the complete application to the FDA, if the sponsor
pays the user fee upon submission of the first portion of the marketing application and the FDA approves a schedule for the
submission  of  the  remaining  sections.  For  products  that  receive  a  priority  review  designation,  the  FDA's  marketing
application review goal is shortened to six months, as opposed to ten months under standard review.

Designation as a fast track product, breakthrough therapy, RMAT, PRIME, or priority review product is within the
discretion  of  the  regulatory  agency.  Accordingly,  even  if  we  believe  one  of  our  product  candidates  meets  the  relevant
criteria, the agency may disagree and instead determine not to make such designation. In any event, the receipt of such a
designation for a product candidate may not result in a faster development process, review or approval compared to drugs
considered for approval under conventional regulatory procedures and does not assure ultimate marketing approval by the
agency. In addition, the FDA may later decide that the products no longer meet the applicable conditions for qualification
as either a fast track product, RMAT, or a breakthrough therapy or, for priority review products, decide that the period for
FDA review or approval will not be shortened.

We  may  not  be  successful  in  our  efforts  to  use  our  gene  therapy  technology  platform  to  build  a  pipeline  of

additional product candidates.

An element of our strategy is to use our gene therapy technology platform to expand our product pipeline and to
progress these candidates through preclinical and clinical development ourselves or together with collaborators. Although
we  currently  have  a  pipeline  of  programs  at  various  stages  of  development,  we  may  not  be  able  to  identify  or  develop
product candidates that are safe and effective. Even if we are successful in continuing to build our pipeline, the potential
product  candidates  that  we  identify  may  not  be  suitable  for  clinical  development.  Research  programs  to  identify  new
product candidates require substantial technical, financial, and human resources. We or any collaborators may focus our
efforts and resources on potential programs or product candidates that ultimately prove to be unsuccessful. If we do not
continue to successfully develop and commercialize product candidates based upon our technology, we may face difficulty
in obtaining product revenues in future periods, which could result in significant harm to our business, results of operations
and financial position and materially adversely affect our share price.

Our strategy of obtaining rights to key technologies through in-licenses may not be successful.

We seek to expand our product pipeline from time to time in part by in-licensing the rights to key technologies,
including  those  related  to  gene  delivery,  genes,  and  gene  cassettes.  The  future  growth  of  our  business  will  depend  in
significant part on our ability to in-license or otherwise acquire the rights to additional product candidates or technologies,
particularly  through  our  collaborations  with  academic  research  institutions.  However,  we  may  be  unable  to  in-license  or
acquire the rights to any such product candidates or technologies from third parties on acceptable terms or at all. The in-
licensing  and  acquisition  of  these  technologies  is  a  competitive  area,  and  many  more  established  companies  are  also
pursuing  strategies  to  license  or  acquire  product  candidates  or  technologies  that  we  may  consider  attractive.  These
established  companies  may  have  a  competitive  advantage  over  us  due  to  their  size,  cash  resources  and  greater  clinical
development  and  commercialization  capabilities.  In  addition,  companies  that  perceive  us  to  be  competitors  may  be
unwilling  to  license  rights  to  us.  Furthermore,  we  may  be  unable  to  identify  suitable  product  candidates  or  technologies
within our areas of focus. If we are unable to successfully obtain rights to suitable product candidates or technologies, our
business, financial condition, and prospects could suffer.

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

Public  perception  may  be  influenced  by  claims  that  gene  therapy  is  unsafe,  and  gene  therapy  may  not  gain  the
acceptance of the public or the medical community. The risk of cancer remains a concern for gene therapy, and we cannot
assure that it will not occur in any of our planned or future clinical studies. In addition, there is the potential risk of 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.

48

Table of Contents

A small number of patients have experienced serious adverse events during our clinical trials of either AMT-060
(our first-generation hemophilia B gene therapy) or etranacogene dezaparvovec. However, adverse events in our clinical
trials or those conducted by other parties (even if not ultimately attributable to our product candidates), and the resulting
publicity, could result in delay, a hold or termination of our clinical trials, increased governmental regulation, unfavorable
public perception, failure of the medical community to accept and prescribe gene therapy treatments, potential regulatory
delays in the testing or approval of our product candidates, stricter labeling requirements for those product candidates that
are approved and a decrease in demand for any such product candidates. If any of these events should occur, it may have a
material adverse effect on our business, financial condition and results of operations.

Certain of our product candidates may require medical devices for product administration and/or diagnostics,
resulting  in  our  product  candidates  being  deemed  combination  products.  This  may  result  in  the  need  to  comply  with
additional regulatory requirements. If we are unable to meet these regulatory requirements, we may be delayed or not be
able to obtain product approval.

Certain  of  our  product  candidates,  such  as  AMT-130,  require  medical  devices,  such  as  a  stereotactic,  magnetic
resonance imaging guided catheter, for product administration. Other of our product candidates may also require the use of
a  companion  diagnostic  device  to  confirm  the  presence  of  specific  genetic  or  other  biomarkers.  This  may  result  in  our
product  candidates  being  deemed  to  be  combination  products,  potentially  necessitating  compliance  with  the  FDA’s
investigational  device  regulations,  separate  marketing  application  submissions  for  the  medical  device  component,  a
demonstration that our product candidates are safe and effective when used in combination with the medical devices, cross
labeling with the medical device, and compliance with certain of the FDA’s device regulations. If we are not able to comply
with  the  FDA’s  device  regulations,  if  we  are  not  able  to  effectively  partner  with  the  applicable  medical  device
manufacturers,  if  we  or  any  partners  are  not  able  to  obtain  any  required  FDA  clearances  or  approvals  of  the  applicable
medical devices, or if we are not able to demonstrate that our product candidates are safe and efficacious when used with
the applicable medical devices, we may be delayed in or may never obtain FDA approval for our product candidates, which
would materially harm our business.

Moreover,  certain  of  our  delivery  modalities,  such  as  direct  delivery  of  product  candidates  to  the  brain,  may
require significant physician ability and skill. If physicians are not able to effectively deliver our product candidates to the
applicable site of action or if delivery modalities are too difficult, we may never be able to obtain approval for our product
candidates,  may  be  delayed  in  obtaining  approval,  or,  following  approval,  physicians  may  not  adopt  our  product
candidates, any of which may materially harm our business.

Risks Related to Our Manufacturing

Our manufacturing facility is subject to significant government regulations and approvals. If we fail to comply

with these regulations or maintain these approvals our business could be materially harmed.

Our manufacturing facility in Lexington is subject to ongoing regulation and periodic inspection by the FDA, EU
member  state,  and  other  regulatory  bodies  to  ensure  compliance  with  current  cGMP  requirements.  Moreover,  before
approving a BLA for any product candidate, the FDA will inspect our manufacturing facility and processes. Any failure to
follow  and  document  our  adherence  to  such  cGMP  regulations  or  other  regulatory  requirements  may  lead  to  significant
delays in the availability of products for commercial sale or clinical study, may result in the termination of or a hold on a
clinical study, or may delay or prevent filing or approval of marketing applications for our products.

Failure to comply with applicable regulations could also result in the FDA, EU member state, or other applicable
authorities  taking  various  actions,  including  levying  fines  and  other  civil  penalties;  imposing  consent  decrees  or
injunctions; requiring us to suspend or put on hold one or more of our clinical trials; suspending or withdrawing regulatory
approvals; delaying or refusing to approve pending applications or supplements to approved applications; requiring us to
suspend  manufacturing  activities  or  product  sales,  imports  or  exports;  requiring  us  to  communicate  with  physicians  and
other  customers  about  concerns  related  to  actual  or  potential  safety,  efficacy,  and  other  issues  involving  our  products;
mandating  or  recommending  product  recalls  or  seizing  products;  imposing  operating  restrictions;  and  seeking  criminal
prosecutions, among other outcomes. Poor control of production processes can also lead to the introduction of adventitious
agents or other contaminants, or to inadvertent changes in the properties or stability of a product candidate that may not be
detectable in final product testing and that could have an adverse effect on clinical studies, or patient safety or efficacy.
Moreover, if our manufacturing facility is not able to follow regulatory requirements, we may need to implement costly and
time-consuming remedial actions. Any of the foregoing could materially harm our business, financial condition, and results
of operations.

49

Table of Contents

Moreover, if we are not able to manufacture a sufficient amount of our product candidates for clinical studies or
eventual  commercialization,  our  development  program  and  eventual  commercial  prospects  will  be  harmed.  If  we  cannot
produce an adequate amount of our product candidates in compliance with the applicable regulatory requirements, we may
need to contract with a third party to do so, in which case third party manufacturers may not be available or available on
favorable  terms.  The  addition  of  a  new  manufacturer  may  also  require  FDA,  EMA,  EU  and  other  regulatory  authority
approvals, which we may not be able to obtain.

Gene  therapies  are  complex  and  difficult  to  manufacture.  We  could  experience  capacity,  production  or
technology  transfer  problems  that  result  in  delays  in  our  development  or  commercialization  schedules  or  otherwise
adversely affect our business.

The  insect-cell  based  manufacturing  process  we  use  to  produce  our  products  and  product  candidates  is  highly
complex and in the normal course is subject to variation or production difficulties. Issues with any of our manufacturing
processes,  even  minor  deviations  from  the  normal  process,  could  result  in  insufficient  yield,  product  deficiencies  or
manufacturing  failures  that  result  in  adverse  patient  reactions,  lot  failures,  insufficient  inventory,  product  recalls  and
product liability claims. Additionally, we may not be able to scale up some or all of our manufacturing processes, that may
result in delays in regulatory approvals or otherwise adversely affect our ability to manufacture sufficient amounts of our
products.

Many  factors  common  to  the  manufacturing  of  most  biologics  and  drugs  could  also  cause  production
interruptions,  including  raw  materials  shortages,  raw  material  failures,  growth  media  failures,  equipment  malfunctions,
facility contamination, labor problems, natural disasters, disruption in utility services, terrorist activities, or cases of force
majeure  and  acts  of  god  (including  the  effects  of  the  Covid  pandemic)  beyond  our  control.  We  also  may  encounter
problems in hiring and retaining the experienced specialized personnel needed to operate our manufacturing process, which
could result in delays in our production or difficulties in maintaining compliance with applicable regulatory requirements.

Any  problems  in  our  manufacturing  processes  or  facilities  could  make  us  a  less  attractive  collaborator  for
academic  research  institutions  and  other  parties,  which  could  limit  our  access  to  additional  attractive  development
programs, result in delays in our clinical development or marketing schedules and materially harm our business.

Our  use  of  viruses,  chemicals  and  other  hazardous  materials  requires  us  to  comply  with  regulatory

requirements and exposes us to significant potential liabilities.

Our development and manufacturing processes involve the use of viruses, chemicals, other (potentially) hazardous
materials and produce waste products. Accordingly, we are subject to national, federal, state, and local laws and regulations
in  the  United  States  and  the  Netherlands  governing  the  use,  manufacture,  distribution,  storage,  handling,  treatment,  and
disposal  of  these  materials.  In  addition  to  ensuring  the  safe  handling  of  these  materials,  applicable  requirements  require
increased safeguards and security measures for many of these agents, including controlling access and screening of entities
and personnel who have access to them, and establishing a comprehensive national database of registered entities. In the
event of an accident or failure to comply with environmental, occupational health and safety and export control laws and
regulations, we could be held liable for damages that result, and any such liability could exceed our assets and resources,
and could result in material harm to our business, financial condition, and results of operations.

Our resources might be adversely affected if we are unable to validate our manufacturing processes or develop

new processes to meet our product supply needs and obligations.

The  manufacture  of  our  AAV  gene  therapies,  including  etranacogene  dezaparvovec,  is  complex  and  requires
significant  expertise.  Even  with  the  relevant  experience  and  expertise,  manufacturers  of  gene  therapy  products  often
encounter  difficulties  in  production,  particularly  in  scaling  out  and  validating  initial  production,  and  ensuring  that  the
product meets required specifications. These problems include difficulties with production costs and yields, quality control,
including stability and potency of the product, quality assurance testing, operator error, shortages of qualified personnel, as
well as compliance with strictly enforced federal, state and foreign regulations. In the past, we have manufactured certain
batches of product candidates, intended for nonclinical, clinical and process validation purposes that have not met all of our
pre-specified quality parameters. To meet our expected future production needs and our regulatory filing timelines for gene
therapy product candidates we will need to complete the validation of our manufacturing processes, and we may need to
develop and validate new or larger scale manufacturing processes. If we are unable to consistently manufacture our gene
therapy  product  candidates  or  any  approved  products  in  accordance  with  our  pre-specified  quality  parameters  and
applicable regulatory standards, it could adversely impact our ability to validate our manufacturing processes, to meet our
production needs, to file a BLA or other regulatory submissions, to develop our other proprietary programs, to conserve
our cash, or to receive financial payments pursuant to our agreements with third parties.

Risks Related to Regulatory Approval of Our Products

We cannot predict when or if we will obtain marketing approval to commercialize a product candidate.

The development and commercialization of our product candidates, including their design, testing, manufacture,
safety, efficacy, purity, recordkeeping, labeling, storage, approval, advertising, promotion, sale, and distribution, are subject
to comprehensive regulation by the FDA and other regulatory agencies in the United States, the EMA, and other regulatory
agencies of the member states of the European Union, and similar regulatory authorities in other jurisdictions. Failure to
obtain  marketing  approval  for  a  product  candidate  in  a  specific  jurisdiction  will  prevent  us  from  commercializing  the
product candidate in that jurisdiction.

The process of obtaining marketing approval for our product candidates in the United States, the European Union,
and other countries is expensive and may take many years, if approval is obtained at all. 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.
Regulatory authorities may also be delayed in completing their review of any marketing applications submitted by us or
our partners.  By example, due to the ongoing COVID-19 pandemic, regulatory authorities may not be able to complete the
pre-approval inspections that are required for approval of a marketing application. Regulatory authorities have substantial
discretion in the approval process and may refuse to accept any application, may decide that our data are insufficient for
approval,  may  require  additional  preclinical,  clinical,  or  other  studies  and  may  not  complete  their  review  in  a  timely
manner. Further, any marketing approval we ultimately obtain may be for only limited indications or be subject to stringent
labeling or other restrictions or post-approval commitments that render the approved product not commercially viable.

If we experience delays in obtaining marketing approval for any of our product candidates in the United States,
the European Union, or other countries, the commercial prospects of our other product candidates may be harmed and our
ability to generate revenues will be materially impaired.

The risks associated with the marketing approval process are heightened by the status of our products as gene

therapies.

We believe that all our current product candidates will be viewed as gene therapy products by the applicable
regulatory authorities. While there are a number of gene therapy product candidates under development, in the United
States, the FDA has only approved a limited number of gene therapy products, to date. Accordingly, regulators, like the
FDA, may have limited experience with the review and approval of marketing applications for gene therapy products.

51

Table of Contents

Both the FDA and the EMA have demonstrated caution in their regulation of gene therapy treatments, and ethical
and  legal  concerns  about  gene  therapy  and  genetic  testing  may  result  in  additional  regulations  or  restrictions  on  the
development and commercialization of our product candidates that are difficult to predict. The FDA and the EMA have
issued  various  guidance  documents  pertaining  to  gene  therapy  products,  with  which  we  likely  must  comply  to  gain
regulatory  approval  of  any  of  our  product  candidates  in  the  United  States  or  European  Union,  respectively.  The  close
regulatory scrutiny of gene therapy products may result in delays and increased costs and may ultimately lead to the failure
to obtain approval for any gene therapy product.

Regulatory requirements affecting gene therapy have changed frequently and continue to evolve, and agencies at
both  the  U.S.  federal  and  state  level,  as  well  as  congressional  committees  and  foreign  governments,  have  sometimes
expressed interest in further regulating biotechnology. In the United States, there have been a number of recent changes
relating to gene therapy development. By example, FDA issued a number of new guidance documents, and continues to
issue  guidance  documents,  on  human  gene  therapy  development,  one  of  which  was  specific  to  human  gene  therapy  for
hemophilia,  one  that  was  specific  to  neurodegenerative  diseases,  and  another  of  which  was  specific  to  rare  diseases.
Moreover, the European Commission conducted a public consultation in early 2013 on the application of EU legislation
that governs advanced therapy medicinal products, including gene therapy products, which could result in changes in the
data we need to submit to the EMA for our product candidates to gain regulatory approval or change the requirements for
tracking,  handling  and  distribution  of  the  products  which  may  be  associated  with  increased  costs.  In  addition,  divergent
scientific  opinions  among  the  various  bodies  involved  in  the  review  process  may  result  in  delays,  require  additional
resources, and ultimately result in rejection. The FDA, EMA, and other regulatory authorities will likely continue to revise
and  further  update  their  approaches  to  gene  therapies  in  the  coming  years.  These  regulatory  agencies,  committees  and
advisory  groups  and  the  new  regulations  and  guidelines  they  promulgate  may  lengthen  the  regulatory  review  process,
require  us  to  perform  additional  studies,  increase  our  development  costs,  lead  to  changes  in  regulatory  positions  and
interpretations,  delay  or  prevent  approval  and  commercialization  of  our  product  candidates  or  lead  to  significant  post-
approval  limitations  or  restrictions.  Delay  or  failure  to  obtain,  or  unexpected  costs  in  obtaining,  the  regulatory  approval
necessary  to  bring  a  potential  product  to  market  could  decrease  our  ability  to  generate  sufficient  product  revenues  to
maintain our business.

Our failure to obtain or maintain orphan product exclusivity for any of our product candidates for which we
seek  this  status  could  limit  our  commercial  opportunity,  and  if  our  competitors  are  able  to  obtain  orphan  product
exclusivity before we do, we may not be able to obtain approval for our competing products for a significant period.

Regulatory authorities in some jurisdictions, including the United States and the European Union, may designate
drugs  for  relatively  small  patient  populations  as  orphan  drugs.  While  certain  of  our  product  candidates  have  received
orphan drug designation, there is no guarantee that we will be able to receive such designations in the future. The FDA
may grant orphan designation to multiple sponsors for the same compound or active molecule and for the same indication.
If  another  sponsor  receives  FDA  approval  for  such  product  before  we  do,  we  would  be  prevented  from  launching  our
product in the United States for the orphan indication for a period of at least seven years unless we can demonstrate clinical
superiority.

Moreover, while orphan drug designation neither shortens the development or regulatory review time, nor gives
the product candidate advantages in the regulatory review or approval process, generally, if a product with an orphan drug
designation subsequently receives the first marketing approval for the relevant indication, the product is entitled to a period
of market exclusivity, which precludes the FDA or the EMA from approving another marketing application for the same
drug for the same indication for that period. The FDA and the EMA, however, may subsequently approve a similar drug or
same drug, in the case of the United States, for the same indication during the first product's market exclusivity period if
the FDA or the EMA concludes that the later drug is clinically superior in that it is shown to be safer or more effective or
makes a major contribution to patient care. Orphan exclusivity in the United States also does not prevent the FDA from
approving  another  product  that  is  considered  to  be  the  same  as  our  product  candidates  for  a  different  indication  or  a
different  product  for  the  same  orphan  indication.  If  another  product  that  is  the  same  as  ours  is  approved  for  a  different
indication, it is possible that third-party payors will reimburse for products off-label even if not indicated for the orphan
condition.

Orphan  drug  exclusivity  may  be  lost  if  the  FDA  or  the  EMA  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 or if the incidence and prevalence of patients who are eligible to receive the drug in these
markets  materially  increase.  The  inability  to  obtain  or  failure  to  maintain  adequate  product  exclusivity  for  our  product
candidates could have a material adverse effect on our business prospects, results of operations and financial condition.

52

Table of Contents

Additionally, regulatory criteria with respect to orphan products is evolving, especially in the area of gene therapy.
By example, in the United States, whether two gene therapies are considered to be the same for the purpose of determining
clinical  superiority  was  recently  updated  via  a  final  guidance  document  specific  to  gene  therapies,  and  depends  on  a
number  of  factors,  including  the  expressed  transgene,  the  vector,  and  other  product  or  product  candidate  features.
Depending on the products, whether two products are ultimately considered to be the same may be determined by FDA on
a case by case basis, making it difficult to make predictions regarding when FDA might be able to make an approval of a
product effective and whether periods of exclusivity will effectively block competitors seeking to market products that are
the same or similar to ours for the same intended use. Accordingly, whether any of our product candidates will be deemed
to be the same as another product or product candidate is uncertain.

As  appropriate,  we  intend  to  seek  all  available  periods  of  regulatory  exclusivity  for  our  product  candidates.
However, there is no guarantee that we will be granted these periods of regulatory exclusivity or that we will be able to
maintain these periods of exclusivity.

The  FDA  grants  product  sponsors  certain  periods  of  regulatory  exclusivity,  during  which  the  agency  may  not
approve,  and  in  certain  instances,  may  not  accept,  certain  marketing  applications  for  competing  drugs.  For  example,
biologic  product  sponsors  may  be  eligible  for  twelve  years  of  exclusivity  from  the  date  of  approval,  seven  years  of
exclusivity for drugs that are designated to be orphan drugs, and/or a six-month period of exclusivity added to any existing
exclusivity period for the submission of FDA requested pediatric data. While we intend to apply for all periods of market
exclusivity that we may be eligible for, there is no guarantee that we will be granted any such periods of market exclusivity.
By  example,  regulatory  authorities  may  determine  that  our  product  candidates  are  not  eligible  for  periods  of  regulatory
exclusivity  for  various  reasons,  including  a  determination  by  the  FDA  that  a  BLA  approval  does  not  constitute  a  first
licensure of the product. Additionally, under certain circumstances, the FDA may revoke the period of market exclusivity.
Thus, there is no guarantee that we will be able to maintain a period of market exclusivity, even if granted. In the case of
orphan designation, other benefits, such as tax credits and exemption from user fees may be available. If we are not able to
obtain or maintain orphan drug designation or any period of market exclusivity to which we may be entitled, we could be
materially  harmed,  as  we  will  potentially  be  subject  to  greater  market  competition  and  may  lose  the  benefits  associated
with  programs.  It  is  also  possible  that  periods  of  exclusivity  will  not  adequately  protect  our  product  candidates  from
competition. For instance, even if we receive twelve years of exclusivity from the FDA, other applicants will still be able to
submit and receive approvals for versions of our product candidates through a full BLA.

If  we  do  not  obtain  or  maintain  periods  of  market  exclusivity,  we  may  face  competition  sooner  than  otherwise
anticipated. For instance, in the United States, this could mean that a competing biosimilar product may be able to submit
an application to the FDA and obtain approval either as a biosimilar to one of our products or even as an interchangeable
product. This may require that we undertake costly and time-consuming patent litigation, to the extent available, or defend
actions  brought  by  the  biosimilar  applicant  for  declaratory  judgment.  If  a  biosimilar  product  does  enter  the  market,  it  is
possible that it could be substituted for one of our product candidates, especially if it is available at a lower price.

It  is  also  possible  that,  at  the  time  we  obtain  approval  of  our  product  candidates,  regulatory  laws  and  policies
around  exclusivities  may  have  changed.  For  instance,  there  have  been  efforts  to  decrease  the  United  States  period  of
exclusivity  to  a  shorter  timeframe.  Future  proposed  budgets,  international  trade  agreements  and  other  arrangements  or
proposals may affect periods of exclusivity.

If  any  of  our  product  candidates  receive  regulatory  approval,  we  and/or  our  partners  will  be  subject  to
extensive  regulatory  requirements.  Failure  to  fulfill  and  comply  with  the  applicable  regulatory  requirements  could
result in regulatory enforcement actions that would be detrimental to our business.

Following any regulatory approval, the FDA and the EMA may impose certain post-approval requirements related
to a product. Specifically, any approved products will be subject to continuing and comprehensive regulation concerning
the  product’s  design,  testing,  manufacture,  safety,  efficacy,  recordkeeping,  labeling,  storage,  approval,  advertising,
promotion, sale and distribution.  Regulatory authorities may also require post-marketing testing, known as Phase 4 testing,
a risk evaluation and mitigation strategy, and surveillance to monitor the effects of an approved product or place conditions
on an approval that could restrict the distribution or use of the product. Failure to comply with any of these requirements
could result in regulatory, administrative, or other enforcement action, that would be detrimental to our business.

53

Table of Contents

For instance, the FDA and other government agencies closely regulate the post-approval marketing and promotion
of  approved  products,  including  off-label  promotion,  industry-sponsored  scientific  and  educational  activities,  and  the
Internet and social media.  Approved products may be marketed only for the approved indications and in accordance with
the  provisions  of  the  approved  labeling.  Failure  to  comply  with  regulatory  promotional  standards  could  result  in  actions
being brought against us by these agencies.

Moreover, if a company obtains FDA approval for a product via the accelerated approval pathway, the company
would be required to conduct a post-marketing confirmatory trial to verify and describe the clinical benefit in support of
full  approval.  An  unsuccessful  post-marketing  study  or  failure  to  complete  such  a  study  could  result  in  the  expedited
withdrawal of the FDA’s marketing approval for a product.

Changes  to  some  of  the  conditions  established  in  an  approved  application,  including  changes  in  labeling,
indications, manufacturing processes or facilities, may require a submission to and approval by the FDA or the EMA, as
applicable, before the change can be implemented. A New Drug Application (“NDA”)/BLA or MAA supplement for a new
indication typically requires clinical data similar to that in the original application. The applicable regulatory authorities
would review such supplement using similar procedures and actions as in reviewing NDAs/BLAs and MAAs.  

Adverse event reporting and submission of periodic reports is required following marketing approval. Regulatory
authorities may withdraw product approvals or request product recalls, as well as impose other enforcement actions, if a
company fails to comply with regulatory standards, if it encounters problems following initial marketing, or if previously
unrecognized problems are subsequently discovered.

In addition, the manufacture, testing, packaging, labeling, and distribution of products after approval will need to
continue to conform to cGMPs. Drug and biological product manufacturers and certain of their subcontractors are subject
to  periodic  unannounced  inspections  by  the  FDA  or  the  EMA  for  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.  In  addition,  prescription  drug  manufacturers  in  the  U.S.  must  comply  with  applicable  provisions  of  the  Drug
Supply Chain Security Act and provide and receive product tracing information, maintain appropriate licenses, ensure they
only work with other properly licensed entities and have procedures in place to identify and properly handle suspect and
illegitimate products.

Where we partner with third parties for the development, approval, and marketing of a product, such third parties
will be subject to the same regulatory obligations as we will.  However, as we will not control the actions of the applicable
third parties, we will be reliant on them to meet their contractual and regulatory obligations.  By example, the decisions
associated with regulatory approvals and filings for AMT-061 will largely be controlled by CSL Behring, and we will not
have final decision making authority in that regard.  Accordingly, actions taken by any of our partners could materially and
adversely impact our business.

Risks Related to Commercialization

If we are unable to successfully commercialize our product candidates or experience significant delays in doing

so, our business could be materially harmed.

Our  ability  to  generate  product  revenues  will  depend  on  the  successful  development  and  eventual
commercialization  of  our  product  candidates.  The  success  of  our  product  candidates  will  depend  on  many  factors,
including:

● successful execution of our contractual relationship with CSL Behring for the commercialization of etranacogene

dezaparvovec;

● successful completion of preclinical studies and clinical trials, and other work required by regulators;
● receipt and maintenance of marketing approvals from applicable regulatory authorities;
● our ability to timely manufacture sufficient quantities of our products according to required quality specifications;
● obtaining  and  maintaining  patent  and  trade  secret  protection  and  non-patent,  orphan  drug  exclusivity  for  our

product candidates;

● obtaining and maintaining regulatory approvals using our manufacturing facility in Lexington, Massachusetts;
● launch and commercialization of our products, if approved, whether alone or in collaboration with others;
● identifying and engaging effective distributors or resellers on acceptable terms in jurisdictions where we plan to

utilize third parties for the marketing and sales of our product candidates;

● acceptance of our products, if approved, by patients, the medical community, and third-party payers;
● effectively competing with existing therapies and gene therapies based on safety and efficacy profiles;

54

Table of Contents

● the strength of our marketing and distribution;
● achieve optimal pricing based on durability of expression, safety, and efficacy;
● the ultimate content of the regulatory authority approved label, including the approved clinical indications, and

any limitations or warnings;

● any distribution or use restrictions imposed by regulatory authorities;
● the interaction of our products with any other medicines that patients may be taking or the restriction on the use

of our products with other medicines;

● the standard of care at the time of product approval;
● the relative convenience and ease of administration of our products;
● obtaining and maintaining healthcare coverage and adequate reimbursement;
● any price concessions, rebates, or discounts we may need to provide;
● complying with any applicable post-approval requirements and maintaining a continued acceptable overall safety

profile; and

● obtaining  adequate  reimbursement  for  the  total  patient  population  and  each  subgroup  to  sustain  a  viable

commercial business model in U.S. and EU markets.

By  example,  even  if  our  product  candidates  are  approved,  they  may  be  subject  to  limitations  that  make
commercialization difficult. There may be limitations on the indicated uses and populations for which the products may be
marketed.  They  may  also  be  subject  to  other  conditions  of  approval,  may  contain  significant  safety  warnings,  including
boxed warnings, contraindications, and precautions, may not be approved with label statements necessary or desirable for
successful  commercialization,  or  may  contain  requirements  for  costly  post-market  testing  and  surveillance,  or  other
requirements,  including  the  submission  of  a  risk  evaluation  and  mitigation  strategy,  or  REMS,  to  monitor  the  safety  or
efficacy of the products. Failure to achieve or implement any of the above elements could result in significant delays or an
inability to successfully commercialize our product candidates, which could materially harm our business.

The  affected  populations  for  our  gene  therapies  may  be  smaller  than  we  or  third  parties  currently  project,

which may affect the size of our addressable markets.

Our projections of the number of people who have the diseases we are seeking to treat, as well as the subset of
people with these diseases who have the potential to benefit from treatment with our therapies, are estimates based on our
knowledge  and  understanding  of  these  diseases.  The  total  addressable  market  opportunities  for  these  therapies  will
ultimately depend upon many factors, including the diagnosis and treatment criteria included in the final label, if approved
for sale in specified indications, acceptance by the medical community, patient consent, patient access and product pricing
and reimbursement.

Prevalence  estimates  are  frequently  based  on  information  and  assumptions  that  are  not  exact  and  may  not  be
appropriate, and the methodology is forward-looking and speculative. The use of such data involves risks and uncertainties
and is subject to change based on various factors. Our estimates may prove to be incorrect and new studies may change the
estimated  incidence  or  prevalence  of  the  diseases  we  seek  to  address.  The  number  of  patients  with  the  diseases  we  are
targeting  may  turn  out  to  be  lower  than  expected  or  may  not  be  otherwise  amenable  to  treatment  with  our  products,
reimbursement may not be sufficient to sustain a viable business for all sub populations being studied, or new patients may
become increasingly difficult to identify or access, any of which could adversely affect our results of operations and our
business.

The  addressable  markets  for  AAV-based  gene  therapies  may  be  impacted  by  the  prevalence  of  neutralizing
antibodies to the capsids, which are an integral component of our gene therapy constructs. Patients that have pre-existing
antibodies to a particular capsid may not be eligible for administration of a gene therapy that includes this particular capsid.
For  example,  etranacogene  dezaparvovec,  our  gene  therapy  candidate  for  hemophilia  B  patients,  incorporates  an  AAV5
capsid.  In  our  Phase  I/II  clinical  study  of  AMT-060,  we  screened  patients  for  pre-existing  anti-AAV5  antibodies  to
determine  their  eligibility  for  the  trial.  Three  of  the  ten  patients  screened  for  the  study  tested  positive  for  anti-AAV5
antibodies  on  reanalysis.  Although  we  did  not  observe  any  ill-effects  or  correlation  between  the  level  of  anti-AAV5
antibodies and clinical outcomes in these three patients, suggesting that patients who have anti-AAV5 antibodies may still
be  eligible  for  AAV5-based  gene  therapies,  since  we  only  have  been  able  to  test  a  limited  number  of  patients  and  have
limited clinical and pre-clinical data, we do not know if future clinical studies will confirm these results. This may limit the
addressable  market  for  etranacogene  dezaparvovec  and  any  future  revenues  derived  from  the  sale  of  the  product,  if
approved.

55

Table of Contents

Any approved gene therapy we seek to offer may fail to achieve the degree of market acceptance by physicians,

patients, third party payers and others in the medical community necessary for commercial success.

Doctors may be reluctant to accept a gene therapy as a treatment option or, where available, choose to continue to
rely  on  existing  treatments.  The  degree  of  market  acceptance  of  any  of  our  product  candidates  that  receive  marketing
approval in the future will depend on many factors, including:

● the efficacy and potential advantages of our therapies compared with alternative treatments;
● our  ability  to  convince  payers  of  the  long-term  cost-effectiveness  of  our  therapies  and,  consequently,  the

availability of third-party coverage and adequate reimbursement;

● the  cost  of  treatment  with  gene  therapies,  including  ours,  in  comparison  to  traditional  chemical  and  small-

molecule treatments;

● the limitations on use and label requirements imposed by regulators;
● the convenience and ease of administration of our gene therapies compared with alternative treatments;
● the willingness of the target patient population to try new therapies, especially a gene therapy, and of physicians

to administer these therapies;

● the strength of marketing and distribution support;
● the prevalence and severity of any side effects;
● limited access to site of service that can perform the product preparation and administer the infusion; and
● any restrictions by regulators on the use of our products.

A  failure  to  gain  market  acceptance  for  any  of  the  above  reasons,  or  any  reasons  at  all,  by  a  gene  therapy  for
which we receive regulatory approval would likely hinder our ability to recapture our substantial investments in that and
other gene therapies and could have a material adverse effect on our business, financial condition, and results of operation.

If  we  are  unable  to  expand  our  commercialization  capabilities  or  enter  into  agreements  with  third  parties  to
market and sell any of our product candidates for which we obtain marketing approval, we may be unable to generate
any product revenue.

To successfully commercialize any products that may result from our development programs, we need to continue
to  expand  our  commercialization  capabilities,  either  on  our  own  or  with  others.  The  development  of  our  own  market
development  effort  is,  and  will  continue  to  be,  expensive  and  time-consuming  and  could  delay  any  product  launch.
Moreover, we cannot be certain that we will be able to successfully develop this capability.

We  may  enter  into  collaborations  regarding  our  other  product  candidates  with  other  entities  to  utilize  their
established marketing and distribution capabilities, but we may be unable to enter into such agreements on favorable terms,
if at all. If any current or future collaborators do not commit sufficient resources to commercialize our products, or we are
unable to develop the necessary capabilities on our own, we will be unable to generate sufficient product revenue to sustain
our  business.  We  compete  with  many  companies  that  currently  have  extensive,  experienced  and  well-funded  medical
affairs, marketing, and sales operations to recruit, hire, train and retain marketing and sales personnel. We also may face
competition  in  any  search  for  third  parties  to  assist  us  with  the  sales  and  marketing  efforts  of  our  product  candidates.
Without an internal team or the support of a third party to perform marketing and sales functions, we may be unable to
compete successfully against these more established companies.

If  the  market  opportunities  for  our  product  candidates  are  smaller  than  we  believe  they  are,  our  product

revenues may be adversely affected, and our business may suffer.

We  focus  our  research  and  product  development  on  treatments  for  severe  genetic  and  orphan  diseases.  Our
understanding of both the number of people who have these diseases, as well as the subset of people with these diseases
who have the potential to benefit from treatment with our product candidates, are based on estimates. These estimates may
prove to be incorrect and new studies may reduce the estimated incidence or prevalence of these diseases. The number of
patients  in  the  United  States,  the  EU  and  elsewhere  may  turn  out  to  be  lower  than  expected,  may  not  be  otherwise
amenable to treatment with our products or patients may become increasingly difficult to identify and access, any of which
could adversely affect our business, financial condition, results of operations and prospects.

56

Table of Contents

Further, there are several factors that could contribute to making the actual number of patients who receive other
potential products less than the potentially addressable market. These include the lack of widespread availability of, and
limited  reimbursement  for,  new  therapies  in  many  underdeveloped  markets.  Further,  the  severity  of  the  progression  of  a
disease  up  to  the  time  of  treatment,  especially  in  certain  degenerative  conditions,  could  diminish  the  therapeutic  benefit
conferred by a gene therapy. Lastly, certain patients’ immune systems might prohibit the successful delivery of certain gene
therapy products to the target tissue, thereby limiting the treatment outcomes.

Our  gene  therapy  approach  utilizes  vectors  derived  from  viruses,  which  may  be  perceived  as  unsafe  or  may
result  in  unforeseen  adverse  events.  Negative  public  opinion  and  increased  regulatory  scrutiny  of  gene  therapy  may
damage public perception of the safety of our product and product candidates and adversely affect our ability to conduct
our business or obtain regulatory approvals for our product candidates.

Gene  therapy  remains  a  novel  technology.  Public  perception  may  be  influenced  by  claims  that  gene  therapy  is
unsafe,  and  gene  therapy  may  not  gain  the  acceptance  of  the  public  or  the  medical  community.  Public  and  medical
community  adoption  of  any  of  our  gene  therapies  will  also  depend  on  factors  including  the  ease  of  administration  in
comparison  to  other  therapeutics.    By  example,  the  need  for  complex  surgeries  for  the  administration  of  a  product
candidate may impact the acceptance of a product.

In particular, our success will depend upon physicians who specialize in the treatment of genetic diseases targeted
by our product and product candidates, prescribing treatments that involve the use of our product and product candidates,
in  lieu  of,  or  in  addition  to,  existing  treatments  with  which  they  are  familiar  and  for  which  greater  clinical  data  may  be
available.  More  restrictive  government  regulations  or  negative  public  opinion  would  have  an  adverse  effect  on  our
business,  financial  condition,  results  of  operations  and  prospects  and  may  delay  or  impair  the  development  and
commercialization  of  our  product  candidates  or  demand  for  any  products  we  may  develop.  For  example,  earlier  gene
therapy trials led to several well-publicized adverse events, including cases of leukemia and death seen in other trials using
other vectors. Serious adverse events in our clinical trials, or other clinical trials involving gene therapy products or our
competitors’  products,  even  if  not  ultimately  attributable  to  the  relevant  product  candidates,  and  the  resulting  publicity,
could result in increased government regulation, unfavorable public perception, potential regulatory delays in the testing or
approval  of  our  product  candidates,  stricter  labeling  requirements  for  those  product  candidates  that  are  approved  and  a
decrease in demand for any products for which we obtain marketing approval.

Ethical,  legal,  and  social  issues  may  reduce  demand  for  any  gene  therapy  products  for  which  we  obtain

marketing approval.

Prior to receiving certain gene therapies, patients may be required to undergo genetic testing. Genetic testing has
raised  concerns  regarding  the  appropriate  utilization  and  the  confidentiality  of  information  provided  by  genetic  testing.
Genetic tests for assessing a person’s likelihood of developing a chronic disease have focused public attention on the need
to  protect  the  privacy  of  genetic  information.  For  example,  concerns  have  been  expressed  that  insurance  carriers  and
employers may use these tests to discriminate on the basis of genetic information, resulting in barriers to the acceptance of
genetic tests by consumers. This could lead to governmental authorities restricting genetic testing or calling for limits on or
regulating  the  use  of  genetic  testing,  particularly  for  diseases  for  which  there  is  no  known  cure.  Any  of  these  scenarios
could decrease demand for any products for which we obtain marketing approval.

If we obtain approval to commercialize any of our product candidates outside of the United States, a variety of

risks associated with international operations could materially adversely affect our business.

We expect that we will be subject to additional risks in commercializing any of our product candidates outside the

United States, including:

● different regulatory requirements for approval of drugs and biologics in foreign countries;
● reduced protection for intellectual property rights;
● unexpected  changes  in  tariffs,  trade  barriers  and  regulatory  requirements  which  may  make  it  more  difficult  or

expensive to export or import products and supplies to or from the United States;

● economic weakness, including inflation, or political instability in particular foreign economies and markets;
● compliance with tax, employment, immigration, and labor laws for employees living or traveling abroad;
● foreign currency fluctuations, which could result in increased operating expenses and reduced revenues, and other

obligations incident to doing business in another country;

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

57

Table of Contents

● production  shortages  resulting  from  any  events  affecting  raw  material  supply  or  manufacturing  capabilities

abroad; and

● business  interruptions  resulting  from  geopolitical  actions,  including  war  and  terrorism  or  natural  disasters

including earthquakes, typhoons, floods, and fires.

We face substantial competition, and others may discover, develop, or commercialize competing products before

or more successfully than we do.

The  development  and  commercialization  of  new  biotechnology  and  biopharmaceutical  products,  including  gene
therapies, is highly competitive. We may face intense competition with respect to our product candidates, as well as with
respect  to  any  product  candidates  that  we  may  seek  to  develop  or  commercialize  in  the  future,  from  large  and  specialty
pharmaceutical  companies  and  biotechnology  companies  worldwide,  who  currently  market  and  sell  products  or  are
pursuing the development of products for the treatment of many of the disease indications for which we are developing our
product  candidates.  Potential  competitors  also  include  academic  institutions,  government  agencies  and  other  public  and
private research organizations that conduct research, seek patent protection, and establish collaborative arrangements for
research,  development,  manufacturing,  and  commercialization.  In  recent  years,  there  has  been  a  significant  increase  in
commercial and scientific interest and financial investment in gene therapy as a therapeutic approach, which has intensified
the competition in this area.

We face worldwide competition from larger pharmaceutical companies, specialty pharmaceutical companies and
biotechnology  firms,  universities  and  other  research  institutions  and  government  agencies  that  are  developing  and
commercializing  pharmaceutical  products.  Our  key  competitors  focused  on  developing  therapies  in  various  indications,
include  among  others,  Pfizer,  Freeline  Therapeutics,  Intellia  Therapeutics,  Sangamo  Biosciences,  Voyager  Therapeutics,
Passage  Bio,  Roche,  PTC  Therapeutics,  Prilenia  Therapeutics,  Triplet  Therapeutics,  CombiGene,  AvroBio,  Caritas
Therapeutics, and 4D Molecular Therapeutics.

Our  commercial  opportunity  could  be  reduced  or  eliminated  if  our  competitors  develop  and  commercialize
products that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive
than  the  products  that  we  develop.  Our  competitors  also  may  obtain  FDA,  EMA,  or  other  regulatory  approval  for  their
products more rapidly than we do, which could result in our competitors establishing a strong market position before we
are able to enter the market. A competitor approval may also prevent us from entering the market if the competitor receives
any regulatory exclusivities that block our product candidates. Because we expect that gene therapy patients may generally
require  only  a  single  administration,  we  believe  that  the  first  gene  therapy  product  to  enter  the  market  for  a  particular
indication will likely enjoy a significant commercial advantage and may also obtain market exclusivity under applicable
orphan drug regimes.

Many  of  the  companies  with  which  we  are  competing  or  may  compete  in  the  future  have  significantly  greater
financial resources and expertise than we do in research and development, manufacturing, preclinical testing, conducting
clinical  trials,  obtaining  regulatory  approvals,  and  marketing  approved  products.  Mergers  and  acquisitions  in  the
pharmaceutical and biotechnology industries may result in more resources being concentrated among a smaller number of
our  competitors.  Smaller  and  other  early-stage  companies  may  also  prove  to  be  significant  competitors,  particularly
through collaborative arrangements with large and established companies. These third parties compete with us in recruiting
and  retaining  qualified  scientific  and  management  personnel,  establishing  clinical  trial  sites  and  patient  registration  for
clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs.

If  we  do  not  achieve  our  projected  development  goals  in  the  timeframes  we  announce  and  expect,  the

commercialization of our product candidates may be delayed and, as a result, our stock price may decline.

For  planning  purposes,  we  estimate  the  timing  of  the  accomplishment  of  various  scientific,  clinical,  regulatory,
and  other  product  development  goals,  or  development  milestones.  These  development  milestones  may  include  the
commencement  or  completion  of  scientific  studies,  clinical  trials,  the  submission  of  regulatory  filings,  and  approval  for
commercial  sale.  From  time  to  time,  we  publicly  announce  the  expected  timing  of  some  of  these  milestones.  All  these
milestones are based on a variety of assumptions. The actual timing of these milestones can vary dramatically compared to
our estimates, in many cases for reasons beyond our control. If we do not meet these milestones, including those that are
publicly announced, the commercialization of our products may be delayed and, as a result, our stock price may decline.

Risks Related to Our Dependence on Third Parties

We  rely,  and  expect  to  continue  to  rely,  on  third  parties  to  conduct,  supervise,  and  monitor  our  preclinical
studies and clinical trials, and those third parties may not perform satisfactorily, including failing to meet deadlines for
the completion of such trials or failing to comply with regulatory requirements.

We  rely  on  third  parties,  study  sites,  and  others  to  conduct,  supervise,  and  monitor  our  preclinical  and  clinical
trials  for  our  product  candidates  and  do  not  currently  plan  to  independently  conduct  clinical  or  preclinical  trials  of  any
other potential product candidates. We expect to continue to rely on third parties, such as CROs, clinical data management
organizations,  medical  and  scientific  institutions,  and  clinical  and  preclinical  investigators,  to  conduct  our  preclinical
studies and clinical trials.

While we have agreements governing the activities of such third parties, we have limited influence and control
over  their  actual  performance  and  activities.  For  instance,  our  third-party  service  providers  are  not  our  employees,  and
except  for  remedies  available  to  us  under  our  agreements  with  such  third  parties  we  cannot  control  whether  or  not  they
devote sufficient time and resources to our ongoing clinical, non-clinical, and preclinical programs. If these third parties do
not  successfully  carry  out  their  contractual  duties,  meet  expected  deadlines  or  conduct  our  preclinical  studies  or  clinical
trials  in  accordance  with  regulatory  requirements  or  our  stated  protocols,  if  they  need  to  be  replaced  or  if  the  quality  or
accuracy of the data they obtain is compromised due to the failure to adhere to our protocols, regulatory requirements or
for other reasons, our trials may be repeated, extended, delayed, or terminated, we may not be able to obtain, or may be
delayed  in  obtaining,  marketing  approvals  for  our  product  candidates,  we  may  not  be  able  to,  or  may  be  delayed  in  our
efforts  to,  successfully  commercialize  our  product  candidates,  or  we  or  they  may  be  subject  to  regulatory  enforcement
actions. As a result, our results of operations and the commercial prospects for our product candidates would be harmed,
our costs could increase and our ability to generate revenues could be delayed. To the extent we are unable to successfully
identify  and  manage  the  performance  of  third-party  service  providers  in  the  future,  our  business  may  be  materially  and
adversely affected. Our third-party service providers may also have relationships with other entities, some of which may be
our competitors, for whom they may also be conducting trials or other therapeutic development activities that could harm
our competitive position.

Our  reliance  on  these  third-parties  for  development  activities  will  reduce  our  control  over  these  activities.
Nevertheless,  we  are  responsible  for  ensuring  that  each  of  our  studies  is  conducted  in  accordance  with  the  applicable
protocol, legal, regulatory, and scientific standards, and our reliance on third parties does not relieve us of our regulatory
responsibilities. For example, we will remain responsible for ensuring that each of our trials is conducted in accordance
with  the  general  investigational  plan  and  protocols  for  the  trial.  We  must  also  ensure  that  our  preclinical  trials  are
conducted  in  accordance  with  GLPs,  as  appropriate.  Moreover,  the  FDA  and  comparable  foreign  regulatory  authorities
require us to comply with GCPs for conducting, recording, and reporting the results of clinical trials to assure that data and
reported results are credible and accurate and that the rights, integrity, and confidentiality of trial participants are protected.
Regulatory  authorities  enforce  these  requirements  through  periodic  inspections  of  trial  sponsors,  clinical  and  preclinical
investigators, and trial sites. If we or any of our third-party service providers fail to comply with applicable GCPs or other
regulatory requirements, we or they may be subject to enforcement or other legal actions, the data generated in our trials
may be deemed unreliable and the FDA or comparable foreign regulatory authorities may require us to perform additional
studies.

In  addition,  we  will  be  required  to  report  certain  financial  interests  of  our  third-party  investigators  if  these
relationships  exceed  certain  financial  thresholds  or  meet  other  criteria.  The  FDA  or  comparable  foreign  regulatory
authorities  may  question  the  integrity  of  the  data  from  those  clinical  trials  conducted  by  investigators  who  may  have
conflicts of interest.

We cannot assure that upon inspection by a given regulatory authority, such regulatory authority will determine
that  any  of  our  trials  complies  with  the  applicable  regulatory  requirements.  In  addition,  our  clinical  trials  must  be
conducted  with  product  candidates  that  were  produced  under  GMP  conditions.  Failure  to  comply  with  these  regulations
may require us to repeat clinical trials, which would delay the regulatory approval process. We also are required to register
certain  clinical  trials  and  post  the  results  of  certain  completed  clinical  trials  on  a  government-sponsored  database,
ClinicalTrials.gov, within specified timeframes. Failure to do so can result in enforcement actions and adverse publicity.

59

Table of Contents

Agreements  with  third  parties  conducting  or  otherwise  assisting  with  our  clinical  or  preclinical  studies  might
terminate for a variety of reasons, including a failure to perform by the third parties. If any of our relationships with these
third  parties  terminate,  we  may  not  be  able  to  enter  into  arrangements  with  alternative  providers  or  to  do  so  on
commercially  reasonable  terms.  Switching  or  adding  additional  third  parties  involves  additional  cost  and  requires
management time and focus. In addition, there is a natural transition period when a new third party commences work. As a
result, if we need to enter into alternative arrangements, it could delay our product development activities and adversely
affect our business. Though we carefully manage our relationships with our third parties, there can be no assurance that we
will  not  encounter  challenges  or  delays  in  the  future  or  that  these  delays  or  challenges  will  not  have  a  material  adverse
impact on our business, financial condition and prospects, and results of operations.

We also rely on other third parties to store and distribute our products for the clinical and preclinical trials that we
conduct.  Any  performance  failure  on  the  part  of  our  distributors  could  delay  development,  marketing  approval,  or
commercialization of our product candidates, producing additional losses and depriving us of potential product revenue.

We  rely  on  third  parties  for  important  aspects  of  our  development  programs.  If  these  parties  do  not  perform
successfully  or  if  we  are  unable  to  enter  into  or  maintain  key  collaboration  or  other  contractual  arrangements,  our
business could be adversely affected.

We have in the past entered into, and expect in the future to enter into, collaborations with other companies and

academic research institutions with respect to important elements of our development programs.

Any collaboration may pose several risks, including the following:

● collaborators  have  significant  discretion  in  determining  the  efforts  and  resources  that  they  will  apply  to  these

collaborations;

● we may have limited or no control over the design or conduct of clinical trials sponsored by collaborators;
● we may be hampered from entering into collaboration arrangements if we are unable to obtain consent from our

licensors to enter into sublicensing arrangements of technology we have in-licensed;

● if any collaborator does not conduct the clinical trials they sponsor in accordance with regulatory requirements or
stated protocols, we will not be able to rely on the data produced in such trials in our further development efforts;

● collaborators may not perform their obligations as expected;
● collaborators may also have relationships with other entities, some of which may be our competitors;
● collaborators may not pursue development and commercialization of any product candidates or may elect not to
continue  or  renew  development  or  commercialization  programs  based  on  clinical  trial  results,  changes  in  the
collaborators' strategic focus or available funding, or external factors, such as an acquisition, that divert resources
or create competing priorities;

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

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

● our collaboration arrangements may impose restrictions on our ability to undertake other development efforts that

may appear to be attractive to us;

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

● a collaborator with marketing and distribution rights that achieves regulatory approval may not commit sufficient

resources to the marketing and distribution of such product or products;

● disagreements with collaborators, including over proprietary rights, contract interpretation or the preferred course
of development, could cause delays or termination of the research, development or commercialization of product
candidates, lead to additional responsibilities for us, delay or impede reimbursement of certain expenses or result
in litigation or arbitration, any of which would be time-consuming and expensive;

60

Table of Contents

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

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

potential liability; and

● collaborations  may  in  some  cases  be  terminated  for  the  convenience  of  the  collaborator  and,  if  terminated,  we
could  be  required  to  expend  additional  funds  to  pursue  further  development  or  commercialization  of  the
applicable product or product candidates.

If  any  collaboration  does  not  result  in  the  successful  development  and  commercialization  of  products  or  if  a
collaborator were to terminate an agreement with us, we may not receive future research funding or milestone or royalty
payments under that collaboration, and we may lose access to important technologies and capabilities of the collaboration.
All the risks relating to product development, regulatory approval and commercialization described herein also apply to the
activities of any development collaborators.

Risks Related to Our Intellectual Property

We  rely  on  licenses  of  intellectual  property  from  third  parties,  and  such  licenses  may  not  provide  adequate
rights or may not be available in the future on commercially reasonable terms or at all, and our licensors may be unable
to obtain and maintain patent protection for the technology or products that we license from them.

We  currently  are  heavily  reliant  upon  licenses  of  proprietary  technology  from  third  parties  that  is  important  or
necessary to the development of our technology and products, including technology related to our manufacturing process,
our vector platform, our gene cassettes and the therapeutic genes of interest we are using. These and other licenses may not
provide adequate rights to use such technology in all relevant fields of use. Licenses to additional third-party technology
that  may  be  required  for  our  development  programs  may  not  be  available  in  the  future  or  may  not  be  available  on
commercially reasonable terms, which could have a material adverse effect on our business and financial condition.

In  some  circumstances,  we  may  not  have  the  right  to  control  the  preparation,  filing  and  prosecution  of  patent
applications, or to maintain the patents, covering technology that we license from third parties. In addition, some of our
agreements with our licensors require us to obtain consent from the licensor before we can enforce patent rights, and our
licensor  may  withhold  such  consent  or  may  not  provide  it  on  a  timely  basis.  Therefore,  we  cannot  be  certain  that  these
patents and applications will be prosecuted and enforced in a manner consistent with the best interests of our business. In
addition, if third parties who license patents to us fail to maintain such patents, or lose rights to those patents, the rights we
have licensed may be reduced or eliminated.

Our  intellectual  property  licenses  with  third  parties  may  be  subject  to  disagreements  over  contract
interpretation, which could narrow the scope of our rights to the relevant intellectual property or technology or increase
our financial or other obligations to our licensors.

The agreements under which we license intellectual property or technology from third parties are complex, and
certain  provisions  in  such  agreements  may  be  susceptible  to  multiple  interpretations.  The  resolution  of  any  contract
interpretation  disagreement  that  may  arise  could  narrow  what  we  believe  to  be  the  scope  of  our  rights  to  the  relevant
intellectual property or technology, or increase what we believe to be our financial or other obligations under the relevant
agreement, either of which could have a material adverse effect on our business and financial condition.

If we fail to comply with our obligations in our intellectual property licenses with third parties, we could lose

rights that are important to our business.

Our  licensing  arrangements  with  third  parties  may  impose  diligence,  development  and  commercialization
timelines, milestone payment, royalty, insurance, and other obligations on us. If we fail to comply with these obligations,
our counterparties may have the right to terminate these agreements either in part or in whole, in which case we might not
be  able  to  develop,  manufacture  or  market  any  product  that  is  covered  by  these  agreements  or  may  face  other  penalties
under  the  agreements.  Such  an  occurrence  could  materially  adversely  affect  the  value  of  the  product  candidate  being
developed under any such agreement. Termination of these agreements or reduction or elimination of our rights under these
agreements may result in our having to negotiate new or amended agreements with less favorable terms or cause us to lose
our rights under these agreements, including our rights to important intellectual property or technology.

61

Table of Contents

If we are unable to obtain and maintain patent protection for our technology and products, or if the scope of

the patent protection is not sufficiently broad, our ability to successfully commercialize our products may be impaired.

We rely, in part, upon a combination of forms of intellectual property, including in-licensed and owned patents to
protect our intellectual property. Our success depends in a large part on our ability to obtain and maintain this protection in
the  United  States,  the  European  Union,  and  other  countries,  in  part  by  filing  patent  applications  related  to  our  novel
technologies and product candidates. Our patents may not provide us with any meaningful commercial protection, prevent
competitors from competing with us or otherwise provide us with any competitive advantage. For example, patents we own
currently are and may become subject to future patent opposition or similar proceedings, which may result in loss of scope
of  some  claims  or  the  entire  patent.  Our  competitors  may  be  able  to  circumvent  our  owned  or  licensed  patents  by
developing similar or alternative technologies or products in a non-infringing manner.

Successful  challenges  to  our  patents  may  result  in  loss  of  exclusivity  or  freedom  to  operate  or  in  patent  claims
being narrowed, invalidated, or held unenforceable, in whole or in part, which could limit our ability to stop others from
using or commercializing similar or identical technology and products, or limit the duration of the patent protection of our
technology and products.

The patent prosecution process is expensive, time-consuming, and uncertain, and we may not be able to file and
prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we
will  fail  to  identify  patentable  aspects  of  our  research  and  development  output  before  it  is  too  late  to  obtain  patent
protection.  Additionally,  given  the  amount  of  time  required  for  the  development,  testing  and  regulatory  review  of  new
product  candidates,  patents  protecting  such  candidates  might  expire  before  or  shortly  after  such  candidates  are
commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude
others from commercializing products similar or identical to ours.

The  patent  position  of  biotechnology  and  pharmaceutical  companies  generally  is  highly  uncertain,  involves
complex legal and factual questions and has in recent years been the subject of much litigation. In addition, the laws of
foreign countries may not protect our rights to the same extent as the laws of the United States. For example, EU patent law
with respect to the patentability of methods of treatment of the human body is more limited than U.S. law. Publications of
discoveries in the scientific literature often lag the actual discoveries, and patent applications in the United States and other
jurisdictions  are  typically  not  published  until  18  months  after  their  priority  date,  or  in  some  cases  at  all.  Therefore,  we
cannot  know  with  certainty  whether  we  were  the  first  to  make  the  inventions  or  that  we  were  the  first  to  file  for  patent
protection  of  the  inventions  claimed  in  our  owned  or  licensed  patents  or  pending  patent  applications.  As  a  result,  the
issuance, scope, validity, enforceability, and commercial value of our patent rights are highly uncertain. Our pending and
future patent applications may not result in patents being issued that protect our technology or products, in whole or in part,
or  which  effectively  prevent  others  from  commercializing  competitive  technologies  and  products.  Changes  in  either  the
patent laws or interpretation of the patent laws in the European Union, the United States or other countries may diminish
the  value  of  our  patents  or  narrow  the  scope  of  our  patent  protection.  Our  inability  to  obtain  and  maintain  appropriate
patent protection for any one of our products could have a material adverse effect on our business, financial condition, and
results of operations.

We  may  become  involved  in  lawsuits  to  protect  or  enforce  our  patents  or  other  intellectual  property,  or  third
parties  may  assert  their  intellectual  property  rights  against  us,  which  could  be  expensive,  time  consuming  and
unsuccessful.

Competitors may infringe our owned or licensed patents or other intellectual property. To counter infringement or
unauthorized  use,  we  may  be  required  to  file  infringement  claims,  which  can  be  expensive  and  time  consuming.  An
adverse result in any litigation proceeding could put one or more of our patents at risk of being invalidated, maintained in
more narrowly amended form or interpreted narrowly.

Even  if  resolved  in  our  favor,  litigation  or  other  legal  proceedings  relating  to  intellectual  property  claims  may
cause  us  to  incur  significant  expenses,  increase  our  operating  losses,  reduce  available  resources,  and  could  distract  our
technical and management personnel from their normal responsibilities. In addition, there could be public announcements
of the results of hearings, motions or other interim proceedings or developments, which could have an adverse effect on the
price of our ordinary shares.

62

Table of Contents

Third parties may initiate legal proceedings alleging that we are infringing their intellectual property rights, the
outcome  of  which  would  be  uncertain  and  could  have  a  material  adverse  effect  on  the  success  of  our  business.  For
example,  outside  of  the  United  States  two  of  the  patents  we  own  are  subject  to  patent  opposition.  If  these  or  future
oppositions are successful or if we are found to otherwise infringe a third party's intellectual property rights, we could be
required to obtain a license from such third party to continue developing and marketing our products and technology. We
may  not  be  able  to  obtain  the  required  license  on  commercially  reasonable  terms  or  at  all.  Even  if  we  could  obtain  a
license, it could be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. We could
be forced, including by court order, to cease commercializing the infringing technology or product or otherwise to cease
using  the  relevant  intellectual  property.  In  addition,  we  could  be  found  liable  for  monetary  damages,  including  treble
damages and attorneys' fees if we are found to have willfully infringed a patent. A finding of infringement could prevent us
from commercializing our product candidates or force us to cease or materially modify some of our business operations,
which  could  materially  harm  our  business.  Claims  that  we  have  misappropriated  the  confidential  information  or  trade
secrets of third parties could have a similar negative impact on our business.

For example, we are aware of patents owned by third parties that relate to some aspects of our programs that are
still  in  development.  In  some  cases,  because  we  have  not  determined  the  final  methods  of  manufacture,  the  method  of
administration or the therapeutic compositions for these programs, we cannot determine whether rights under such third-
party  patents  will  be  needed.  In  addition,  in  some  cases,  we  believe  that  the  claims  of  these  patents  are  invalid  or  not
infringed or will expire before commercialization. However, if such patents are needed and found to be valid and infringed,
we could be required to obtain licenses, which might not be available on commercially reasonable terms, or to cease or
delay commercializing certain product candidates, or to change our programs to avoid infringement.

If we are unable to protect the confidentiality of our proprietary information and know-how, the value of our

technology and products could be adversely affected.

In  addition  to  seeking  patent  protection,  we  also  rely  on  other  proprietary  rights,  including  protection  of  trade
secrets, know-how and confidential and proprietary information. To maintain the confidentiality of our trade secrets and
proprietary information, we enter into confidentiality agreements with our employees, consultants, collaborators and other
third  parties  who  have  access  to  our  trade  secrets.  Our  agreements  with  employees  also  provide  that  any  inventions
conceived  by  the  individual  while  rendering  services  to  us  will  be  our  exclusive  property.  However,  we  may  not  obtain
these agreements in all circumstances, and individuals with whom we have these agreements may not comply with their
terms.  The  assignment  of  intellectual  property  rights  may  not  be  self-executing,  or  the  assignment  agreements  may  be
breached, and we may be forced to bring claims against third parties, or defend claims that they may bring against us, to
determine the ownership of what we regard as our intellectual property. In addition, in the event of unauthorized use or
disclosure of our trade secrets or proprietary information, these agreements, even if obtained, may not provide meaningful
protection,  particularly  for  our  trade  secrets  or  other  confidential  information.  To  the  extent  that  our  employees,
consultants,  or  contractors  use  technology  or  know-how  owned  by  third  parties  in  their  work  for  us,  disputes  may  arise
between us and those third parties as to the rights in related inventions.

 Adequate remedies may not exist in the event of unauthorized use or disclosure of our confidential information
including a breach of our confidentiality agreements. Enforcing a claim that a party illegally disclosed or misappropriated a
trade secret is difficult, expensive, and time consuming, and the outcome is unpredictable. In addition, some courts in and
outside  of  the  United  States  are  less  willing  or  unwilling  to  protect  trade  secrets.  If  any  of  our  trade  secrets  were  to  be
lawfully obtained or independently developed by a competitor or other third party, we would have no right to prevent them
from  using  that  technology  or  information  to  compete  with  us.  The  disclosure  of  our  trade  secrets  or  the  independent
development  of  our  trade  secrets  by  a  competitor  or  other  third  party  would  impair  our  competitive  position  and  may
materially harm our business, financial condition, results of operations, stock price and prospects.

Our reliance on third parties may require us to share our trade secrets, which could increase the possibility that

a competitor will discover them or that our trade secrets will be misappropriated or disclosed.

Because  we  collaborate  from  time  to  time  with  various  organizations  and  academic  research  institutions  on  the
advancement  of  our  gene  therapy  platform,  we  must,  at  times,  share  trade  secrets  with  them.  We  seek  to  protect  our
proprietary technology in part by entering into confidentiality agreements and, if applicable, materials transfer agreements,
collaborative research agreements, consulting agreements or other similar agreements with our collaborators, advisors, and
consultants prior to beginning research or disclosing proprietary information. These agreements typically limit the rights of
the third parties to use or disclose our confidential information, such as trade secrets. Despite the contractual provisions
employed when working with third parties, the need to share trade secrets and other confidential information increases the
risk that such trade secrets become known by our competitors, are inadvertently incorporated into the technology of others,
or are disclosed or used in violation of these agreements. Given that our proprietary position is based, in part, on our know-
how and trade secrets, a competitor's discovery of our trade secrets or other unauthorized use or disclosure would impair
our competitive position and may have a material adverse effect on our business.

In addition, these agreements typically restrict the ability of our collaborators, advisors, and consultants to publish
data  potentially  relating  to  our  trade  secrets.  Our  academic  collaborators  typically  have  rights  to  publish  data,  if  we  are
notified in advance and may delay publication for a specified time to secure our intellectual property rights arising from the
collaboration.  In  other  cases,  publication  rights  are  controlled  exclusively  by  us,  although  in  some  cases  we  may  share
these rights with other parties. We also conduct joint research and development programs that may require us to share trade
secrets under the terms of our research and development partnerships or similar agreements.

Some courts inside and outside the United States are less willing or unwilling to protect trade secrets. If any of our
trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent
them, or those with whom they communicate, from using that technology or information to compete with us.

Risks Related to Acquisitions

Our  acquisition  strategy  may  not  produce  the  cash  flows  expected  or  could  result  in  additional  costs  and

challenges.

Any acquisition, including the recent acquisition of Corlieve Therapeutics, could expose us to unknown liabilities
and risks, and we may incur additional costs and expenses necessary to address an acquired company’s failure to comply
with laws and governmental rules and regulations. We could incur additional costs related to resources to align our business
practices and operations. Moreover, we cannot assure that the anticipated benefits of any acquisition would be realized in a
timely manner, if at all.

In  addition,  the  finalization  of  the  valuation  of  the  identifiable  assets  acquired  in  connection  with  the  Corlieve
Transaction  could  require  us  to  expense  all  identifiable  intangible  assets  without  an  alternative  future  use  if  we  would
determine  that  substantially  all  of  the  gross  value  of  the  assets  is  concentrated  in  a  single  identifiable  asset  or  group  of
similar identifiable assets.

Additionally, the product candidate and intellectual property rights that we acquired in the Corlieve Transaction
were developed and owned by Corlieve and its licensors and we have not yet demonstrated an ability to develop, advance,
or run clinical trials with this product candidate. As a result, we cannot ensure that we will be able to successfully advance
this product candidate going forward.

Risks Related to Pricing and Reimbursement

We face uncertainty related to insurance coverage of, and pricing and reimbursement for product candidates

for which we may receive marketing approval.

We  anticipate  that  the  cost  of  treatment  using  our  product  candidates  will  be  significant.  We  expect  that  most
patients and their families will not be capable of paying for our products themselves. There will be no commercially viable
market  for  our  product  candidates  without  reimbursement  from  third  party  payers,  such  as  government  health
administration authorities, private health insurers and other organizations. Even if there is a commercially viable market, if
the level of third-party reimbursement is below our expectations, most patients may not be able to afford treatment with our
products and our revenues and gross margins will be adversely affected, and our business will be harmed.

64

Table of Contents

Government  authorities  and  other  third-party  payers,  such  as  private  health  insurers  and  health  maintenance
organizations,  decide  for  which  medications  they  will  pay  and,  subsequently,  establish  reimbursement  levels.
Reimbursement systems vary significantly by country and by region, and reimbursement approvals must be obtained on a
country-by-country  basis.  Government  authorities  and  third-party  payers  have  attempted  to  control  costs  by  limiting
coverage and the amount of reimbursement for particular medications and procedures and negotiating or requiring payment
of  manufacturer  rebates.  Increasingly,  third  party  payers  require  drug  companies  to  provide  them  with  predetermined
discounts from list prices, are exerting influence on decisions regarding the use of particular treatments and are limiting
covered indications. Additionally, in the United States and some foreign jurisdictions, pending or potential legislative and
regulatory changes regarding the healthcare system and insurance coverage could result in more rigorous coverage criteria
and  downward  pressure  on  drug  prices,  and  may  affect  our  ability  to  profitably  sell  any  products  for  which  we  obtain
marketing approval. For example, on November 27, 2020, CMS issued an interim final rule implementing a Most Favored
Nation  (“MFN”)  payment  model  under  which  reimbursement  for  certain  Medicare  Part  B  drugs  and  biologicals  will  be
based on a price that reflects the lowest per capita GDP-adjusted price of any non-U.S. member country of the OECD with
a  GDP  per  capita  that  is  at  least  sixty  percent  of  the  U.S.  GDP  per  capita.  While  this  rule  now  has  been  rescinded,
government negotiation of certain Medicare drug pricing continues to be the focus of recent proposed legislation.

The pricing review period and pricing negotiations for new medicines take considerable time and have uncertain
results.  Pricing  review  and  negotiation  usually  begins  only  after  the  receipt  of  regulatory  marketing  approval,  and  some
authorities  require  approval  of  the  sale  price  of  a  product  before  it  can  be  marketed.  In  some  markets,  particularly  the
countries  of  the  European  Union,  prescription  pharmaceutical  pricing  remains  subject  to  continuing  direct  governmental
control and to drug reimbursement programs even after initial approval is granted and price reductions may be imposed.
Prices of medical products may also be subject to varying price control mechanisms or limitations as part of national health
systems if products are considered not cost-effective or where a drug company's profits are deemed excessive. In addition,
pricing  and  reimbursement  decisions  in  certain  countries  can  lead  to  mandatory  price  reductions  or  additional
reimbursement  restrictions  in  other  countries.  Because  of  these  restrictions,  any  product  candidates  for  which  we  may
obtain marketing approval may be subject to price regulations that delay or prohibit our or our partners' commercial launch
of the product in a particular jurisdiction. In addition, we or any collaborator may elect to reduce the price of our products
to  increase  the  likelihood  of  obtaining  reimbursement  approvals.  If  countries  impose  prices,  which  are  not  sufficient  to
allow us or any collaborator to generate a profit, we or any collaborator may refuse to launch the product in such countries
or withdraw the product from the market. If pricing is set at unsatisfactory levels, or if the price decreases, our business
could be harmed, possibly materially. If we fail to obtain and sustain an adequate level of coverage and reimbursement for
our products by third party payers, our ability to market and sell our products could be adversely affected and our business
could be harmed.

Due  to  the  generally  limited  addressable  market  for  our  target  orphan  indications  and  the  potential  for  our
therapies  to  offer  therapeutic  benefit  in  a  single  administration,  we  face  uncertainty  related  to  pricing  and
reimbursement for these product candidates.

The relatively small market size for orphan indications and the potential for long-term therapeutic benefit from a
single  administration  present  challenges  to  pricing  review  and  negotiation  of  our  product  candidates  for  which  we  may
obtain  marketing  authorization.  Most  of  our  product  candidates  target  rare  diseases  with  relatively  small  patient
populations.  If  we  are  unable  to  obtain  adequate  levels  of  reimbursement  relative  to  these  small  markets,  our  ability  to
support  our  development  and  commercial  infrastructure  and  to  successfully  market  and  sell  our  product  candidates  for
which we may obtain marketing approval could be adversely affected.

We also anticipate that many or all our gene therapy product candidates may provide long-term, and potentially
curative  benefit,  with  a  single  administration.  This  is  a  different  paradigm  than  that  of  other  pharmaceutical  therapies,
which often require an extended course of treatment or frequent administration. As a result, governments and other payers
may be reluctant to provide the significant level of reimbursement that we seek at the time of administration of our gene
therapies or may seek to tie reimbursement to clinical evidence of continuing therapeutic benefit over time. Additionally,
there may be situations in which our product candidates will need to be administered more than once, which may further
complicate  the  pricing  and  reimbursement  for  these  treatments.  In  addition,  considering  the  anticipated  cost  of  these
therapies, governments and other payers may be particularly restrictive in making coverage decisions. These factors could
limit our commercial success and materially harm our business.

Risks Related to Our Financial Position and Need for Additional Capital

We had a gain in the current year and incurred significant losses in prior years and expect to incur losses over

the next several years and may never achieve or maintain profitability.

We had a gain of $329.6 million in the year ended December 31, 2021, and incurred losses of $125.0 million in
2020 and $124.2 million in 2019. As of December 31, 2021, we had an accumulated deficit of $455.1 million. In the past,
we have financed our operations primarily through the sale of equity securities and convertible debt, venture loans, upfront
payments from our collaboration partners and, to a lesser extent, subsidies and grants from governmental agencies and fees
for services. We expect to finance our operations in 2022 primarily from the $462.4 million payments we collected from
CSL Behring in May 2021 as well as the $55.0 million we expect to collect from CSL Behring in 2022. We have devoted
substantially all our financial resources and efforts to research and development, including preclinical studies and clinical
trials. We expect to continue to incur significant expenses and losses over the next several years, and our net losses may
fluctuate significantly from quarter to quarter and year to year. Our gain was materially impacted by the amount of license
revenue that we recognized as a result of the Closing of the transaction under the CSL Behring Agreement.

We anticipate that our expenses will increase substantially as we:
● advance the clinical development of AMT-130, for our Huntington’s disease gene therapy program;
● advance  multiple  research  programs  related  to  gene  therapy  candidates  targeting  liver-directed  and  CNS

diseases;

● continue  to  expand  our  employee  base  to  support  research  and  development,  as  well  as  general  and

administrative functions;

● acquire or in-license rights to new therapeutic targets or product candidates;
● continue  to  expand,  enhance,  and  optimize  our  technology  platform,  including  our  manufacturing

capabilities, next-generation viral vectors and promoters, and other enabling technologies;

● maintain, expand, and protect our intellectual property portfolio, including in-licensing additional intellectual

property rights from third parties; and

● make potential future milestone payments related to the acquisition of Corlieve, if any.

We may never succeed in these activities and, even if we do, may never generate revenues that are sufficient to
achieve or sustain profitability. Our failure to become and remain profitable would depress the value of our company and
could  impair  our  ability  to  expand  our  business,  maintain  our  research  and  development  efforts,  diversify  our  product
offerings, or even continue our operations.

We  will  likely  need  to  raise  additional  funding,  which  may  not  be  available  on  acceptable  terms,  or  at  all.
Failure to obtain capital when needed may force us to delay, limit or terminate our product development efforts or other
operations which could have a material adverse effect on our business, financial condition, results of operations and
cash flows.

We expect to incur significant expenses in connection with our on-going activities and that we will likely need to
obtain substantial additional funding in connection with our continuing operations. In addition, we have based our estimate
of our financing requirements on assumptions that may prove to be wrong, and we could use our capital resources sooner
than we currently expect.

Adequate capital may not be available to us when needed or may not be available on acceptable terms. Our ability
to obtain debt financing may be limited by covenants we have made under our 2021 Restated Facility with Hercules and
our pledge to Hercules of substantially all our assets as collateral. If we raise additional capital through the sale of equity or
convertible  debt  securities,  our  shareholders'  ownership  interest  could  be  diluted,  and  the  terms  of  these  securities  may
include liquidation or other preferences that adversely affect the rights of holders of our ordinary shares.

If  we  raise  additional  funds  through  collaborations,  strategic  alliances,  or  marketing,  distribution,  or  licensing
arrangements  with  third  parties,  we  may  have  to  issue  additional  equity,  relinquish  valuable  rights  to  our  technologies,
future revenue streams, products, or product candidates, or grant licenses on terms that may not be favorable to us. If we
are  unable  to  raise  capital  when  needed  or  on  attractive  terms,  we  could  be  forced  to  delay,  reduce,  or  eliminate  our
research and development programs or any future commercialization efforts, which would have a negative impact on our
financial condition, results of operations and cash flows.

66

Table of Contents

Our existing and any future indebtedness could adversely affect our ability to operate our business.

As of December 31, 2021, we had $100.0 million of outstanding principal of borrowings under the 2021 Restated
Facility, which we are required to repay in equal installments between December 2024 and December 2025 or in full in
December 2025 if, prior to June 30, 2024, either (a) the BLA for AMT-061 is approved by the FDA or (b) AMT-130 is
advanced  into  a  pivotal  trial.  We  could  in  the  future  incur  additional  debt  obligations  beyond  our  borrowings  from
Hercules. Our existing loan obligations, together with other similar obligations that we may incur in the future, could have
significant adverse consequences, including:

● requiring us to dedicate a portion of our cash resources to the payment of interest and principal, reducing money
available  to  fund  working  capital,  capital  expenditures,  research  and  development  and  other  general  corporate
purposes;

● increasing our vulnerability to adverse changes in general economic, industry and market conditions;
● subjecting us to restrictive covenants that may reduce our ability to take certain corporate actions or obtain further

debt or equity financing;

● limiting  our  flexibility  in  planning  for,  or  reacting  to,  changes  in  our  business  and  the  industry  in  which  we

compete; and

● placing us at a disadvantage compared to our competitors that have less debt or better debt servicing options.

We may not have sufficient funds, and may be unable to arrange for additional financing, to pay the amounts due
under  our  existing  loan  obligations.  Failure  to  make  payments  or  comply  with  other  covenants  under  our  existing  debt
could result in an event of default and acceleration of amounts due. Under the 2021 Restated Facility, the occurrence of an
event that would reasonably be expected to have a material adverse effect on our business, operations, assets, or condition
is an event of default. If an event of default occurs and the lender accelerates the amounts due, we may not be able to make
accelerated payments, and the lender could seek to enforce security interests in the collateral securing such indebtedness,
which includes substantially all our assets.

Risks Related to Other Legal Compliance Matters

Our  relationships  with  customers  and  third-party  payers  will  be  subject  to  applicable  anti-kickback,  anti-
bribery, fraud and abuse and other laws and regulations, which, if we are found in violation thereof, could expose us to
criminal sanctions, civil and administrative penalties, contractual damages, reputational harm and diminished profits
and future earnings.

Healthcare  providers,  physicians,  other  practitioners,  and  third-party  payers  will  play  a  primary  role  in  the
recommendation and prescription of any products for which we obtain marketing approval. Our future arrangements with
third  party  payers  and  customers  may  expose  us  to  broadly  applicable  anti-bribery  laws,  including  the  Foreign  Corrupt
Practices Act, as well as fraud and abuse and other US and international healthcare laws and regulations that may constrain
the business or financial arrangements and relationships through which we would be able to market, sell and distribute any
products for which we obtain marketing approval.

Efforts  to  ensure  that  our  business  arrangements  with  third  parties  will  comply  with  applicable  laws  and
regulations  could  involve  substantial  costs.  If  our  operations,  or  the  activities  of  our  collaborators,  distributors  or  other
third-party agents are found to be in violation of any of these laws or any other governmental regulations that may apply to
us, we may be subject to significant civil, criminal, and administrative penalties, damages, fines, imprisonment, exclusion
from participation in government funded healthcare programs and the curtailment or restructuring of our operations. The
costs  associated  with  any  of  these  actions  could  be  substantial  and  could  cause  irreparable  harm  to  our  reputation  or
otherwise have a material adverse effect on our business, financial condition, and results of operations.

67

Table of Contents

We  are  subject  to  laws  governing  data  protection  in  the  different  jurisdictions  in  which  we  operate.  The
implementation of such data protection regimes is complex, and should we fail to fully comply, we may be subject to
penalties that may have an adverse effect on our business, financial condition, and results of operations.

Many national and state laws govern the privacy and security of health information and other personal and private
information. They often differ from each other in significant ways. For instance, the EU has adopted a comprehensive data
protection law called the General Data Protection Regulation (“GDPR”) that took effect in May 2018. The GDPR, together
with the national legislation of the EU member states governing the processing of personal data, impose strict obligations
and restrictions on the ability to collect, analyze and transfer personal data, including health data from clinical trials and
adverse event reporting. In particular, these obligations and restrictions concern the consent of the individuals to whom the
personal  data  relates,  the  information  provided  to  the  individuals,  the  transfer  of  personal  data  out  of  the  EU,  security
breach  notifications,  security  and  confidentiality  of  the  personal  data,  and  imposition  of  substantial  potential  fines  for
breaches of the data protection obligations. The GDPR imposes penalties for non-compliance of up to the greater of EUR
20.0 million or 4% of worldwide revenue. Data protection authorities from the different EU member states may interpret
the GDPR and national laws differently and impose additional requirements, which add to the complexity of processing
personal data in the EU. Guidance on implementation and compliance practices are often updated or otherwise revised. The
significant costs of compliance with risk of regulatory enforcement actions under, and other burdens imposed by the GDPR
as well as under other regulatory schemes throughout the world related to privacy and security of health information and
other personal and private data could have an adverse impact on our business, financial condition, and results of operations.

Product liability lawsuits could cause us to incur substantial liabilities and to limit commercialization of our

therapies.

We face an inherent risk of product liability related to the testing of our product candidates in human clinical trials
and in connection with product sales. If we cannot successfully defend ourselves against claims that our product candidates
or products caused injuries, we will incur substantial liabilities. Regardless of merit or eventual outcome, liability claims
may result in:

● decreased demand for any product candidates or products that we develop or sell;
● injury to our reputation and significant negative media attention;
● negative publicity or public opinion surrounding gene therapy;
● withdrawal of clinical trial participants or sites, or discontinuation of development programs;
● significant costs to defend the related litigation;
● substantial monetary awards to trial participants or patients;
● loss of revenue;
● initiation of investigations, and enforcement actions by regulators; and product recalls, withdrawals, revocation of

approvals, or labeling, marketing, or promotional restrictions;

● reduced resources of our management to pursue our business strategy; and
● the inability to further develop or commercialize any products that we develop.

Dependent upon the country where the clinical trial is conducted, we currently hold coverages ranging from EUR
500,000 to EUR 6,500,000 per occurrence and per clinical trial. Such coverage may not be adequate to cover all liabilities
that we may incur. We may need to increase our insurance coverage as we expand our clinical trials. 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. In the event insurance coverage is insufficient to cover liabilities
that we may incur, it could have a material adverse effect on our business, financial condition, and results of operations.

Healthcare  legislative  and  regulatory  reform  measures  may  have  a  material  adverse  effect  on  our  financial

operations.

Our industry is highly regulated and changes in law may adversely impact our business, operations, or financial
results. The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act,
or  the  PPACA,  is  a  sweeping  measure  intended  to,  among  other  things,  expand  healthcare  coverage  within  the  United
States, primarily through the imposition of health insurance mandates on employers and individuals and expansion of the
Medicaid program. Several provisions of the law may affect us and increase certain of our costs.

68

Table of Contents

In  addition,  other  legislative  changes  have  been  adopted  since  the  PPACA  was  enacted.  These  changes  include
aggregate reductions in Medicare payments to providers of 2% per fiscal year, which went into effect on April 1, 2013,
Congress subsequently has extended the period over which these reductions are in effect. While President Biden previously
signed  legislation  temporarily  to  eliminate  this  reduction  through  the  end  of  2021,  recent  legislation  will  restart  the
reductions, which will thereafter remain in effect through 2031 unless additional congressional action is taken. In January
2013,  President  Obama  signed  into  law  the  American  Taxpayer  Relief  Act  of  2012,  which,  among  other  things,  further
reduced Medicare payments to several types of providers and increased the statute of limitations period for the government
to recover overpayments to providers from three to five years. These laws may result in additional reductions in Medicare
and other healthcare funding, which could have a material adverse effect on our customers and, accordingly, our financial
operations.

We anticipate that the PPACA, as well as other healthcare reform measures that may be adopted in the future, may
result  in  more  rigorous  coverage  criteria  and  additional  downward  pressure  on  pricing  and  the  reimbursement  our
customers  may  receive  for  our  products,  and  increased  manufacturer  rebates.  Further,  there  have  been,  and  there  may
continue to be, judicial and Congressional challenges to certain aspects of the PPACA. For example, the U.S. Tax Cuts and
Jobs  Act  of  2017  includes  a  provision  repealing,  effective  January  1,  2019,  the  tax-based  shared  responsibility  payment
imposed by the Affordable Care Act on certain individuals who fail to maintain qualifying health coverage for all or part of
a  year  that  is  commonly  referred  to  as  the  "individual  mandate".  Additional  legislative  and  regulatory  changes  to  the
PPACA, its implementing regulations and guidance and its policies, remain possible in the 117th U.S. Congress and under
the Biden Administration. However, it remains unclear how any new legislation or regulation might affect the prices we
may obtain for any of our product candidates for which regulatory approval is obtained. Any reduction in reimbursement
from  Medicare  and  other  government  programs  may  result  in  a  similar  reduction  in  payments  from  private  payers.  The
implementation  of  cost  containment  measures  or  other  healthcare  reforms  may  prevent  us  from  being  able  to  generate
revenue, attain profitability or commercialize our products.

Our internal computer systems, or those of our collaborators or other contractors or consultants, may fail or

suffer security breaches, which could result in a material disruption of our product development programs.

Our  internal  computer  systems  and  those  of  our  current  and  any  future  collaborators  and  other  contractors  or
consultants  are  vulnerable  to  damage  from  computer  viruses,  unauthorized  access,  natural  disasters,  terrorism,  war  and
telecommunication and electrical failures. The size and complexity of our information technology systems, and those of
our collaborators, contractors and consultants, and the large amounts of confidential information stored on those systems,
make such systems vulnerable to service interruptions or to security breaches from inadvertent or intentional actions by our
employees, third-party vendors and/or business partners, or from cyber-attacks by malicious third parties. Cyber-attacks are
increasing in their frequency, sophistication, and intensity, and have become increasingly difficult to detect. Cyber-attacks
could  include  the  deployment  of  harmful  malware,  ransomware,  denial-of-service  attacks,  social  engineering,  and  other
means to affect service reliability and threaten the confidentiality, integrity, and availability of information. Cyber-attacks
also could include phishing attempts or e-mail fraud to cause payments or information to be transmitted to an unintended
recipient. The increased number of employees working remotely due to Covid might increase our vulnerability to the above
risk.

While  we  have  experienced  and  addressed  system  failures,  cyber-attacks,  and  security  breaches  in  the  past,  we
have not experienced a system failure, accident, cyber-attack, or security breach that has resulted in a material interruption
in our operations to date. In the future, such events could result in a material disruption of our development programs and
our business operations, whether due to a loss of our trade secrets, data, or other proprietary information or other similar
disruptions.  Additionally,  any  such  event  that  leads  to  unauthorized  access,  use  or  disclosure  of  personal  information,
including  personal  information  regarding  our  patients  or  employees,  could  harm  our  reputation,  cause  us  not  to  comply
with federal and/or state breach notification laws and foreign law equivalents and otherwise subject us to liability under
laws  and  regulations  that  protect  the  privacy  and  security  of  personal  information.  Security  breaches  and  other
inappropriate access can be difficult to detect, and any delay in identifying them may lead to increased harm of the type
described  above.  While  we  have  implemented  security  measures  to  protect  our  information  technology  systems  and
infrastructure,  there  can  be  no  assurance  that  such  measures  will  prevent  service  interruptions  or  security  breaches  that
could  adversely  affect  our  business  and  the  further  development  and  commercialization  of  our  product  and  product
candidates could be delayed.

Risks Related to Employee Matters and Managing Growth

Our future success depends on our ability to retain key executives, technical staff, and other employees and to

attract, retain and motivate qualified personnel.

Our  future  growth  and  success  will  depend  in  large  part  on  our  continued  ability  to  attract,  retain,  manage  and
motivate our employees. The loss of the services of any member of our senior management or the inability to hire or retain
experienced management personnel could adversely affect our ability to execute our business plan and harm our operating
results.  We  are  highly  dependent  on  hiring,  training,  retaining  and  motivating  key  personnel  to  lead  our  research  and
development, clinical operations, and manufacturing efforts. Although we have entered into employment agreements with
our key personnel, each of them may terminate their employment on short notice. We do not maintain key person insurance
for any of our senior management or employees.

The  loss  of  the  services  of  our  key  employees  could  impede  the  achievement  of  our  research  and  development
objectives  and  seriously  harm  our  ability  to  successfully  implement  our  business  strategy.  Furthermore,  replacing  senior
management  and  key  employees  may  be  difficult  and  may  take  an  extended  period  because  of  the  limited  number  of
individuals  in  our  industry  with  the  breadth  and  depth  of  skills  and  experience  required  to  successfully  develop  gene
therapy  products.  Competition  to  hire  from  this  limited  pool  is  intense,  and  we  may  be  unable  to  hire,  train,  retain  or
motivate these key personnel on acceptable terms.

The  competition  for  qualified  personnel  in  the  pharmaceutical  field  is  intense,  and  there  is  a  limited  pool  of
qualified potential employees to recruit. Due to this intense competition, we may be unable to continue to attract and retain
qualified personnel necessary for the development of our business or to recruit suitable replacement personnel. If we are
unable to continue to attract and retain high quality personnel, our ability to pursue our business may be harmed and our
growth strategy may be limited.

Additionally, we are reliant on our employees, contractors, consultants, vendors and other parties with whom we
have relationships to behave ethically and within the requirements of the law.  The failure of any employee or other such
third parties to act within the bounds of the applicable laws, regulations, agreements, codes and other requirements, or any
misconduct or illegal actions or omissions by such persons, could materially damage our business.

Risks Related to Our Ordinary Shares

The price of our ordinary shares has been and may in the future be volatile and fluctuate substantially.

Our share price has been and may in the future be volatile. From the start of trading of our ordinary shares on the
Nasdaq Global Select Market on February 4, 2014 through February 23, 2022, the sale price of our ordinary shares ranged
from a high of $82.49 to a low of $4.72. The closing price on February 23, 2022, was $15.70 per ordinary share. The stock
market  in  general  and  the  market  for  smaller  biopharmaceutical  companies  in  particular,  have  experienced  extreme
volatility  that  has  often  been  unrelated  to  the  operating  performance  of  particular  companies.  The  market  price  for  our
ordinary shares may be influenced by many factors, including:

● the success of competitive products or technologies;
● results of clinical trials of our product candidates or those of our competitors;

Our directors, executive officers, and major shareholders, if they choose to act together, will continue to have a

significant degree of control with respect to matters submitted to shareholders for approval.

Our directors, executive officers and major shareholders holding more than 5% of our outstanding ordinary shares,
in the aggregate, beneficially own approximately 50.4% of our issued shares (including such shares to be issued in relation
to  exercisable  options  to  purchase  ordinary  shares)  as  at  December  31,  2021.  As  a  result,  if  these  shareholders  were  to
choose to act together, they may be able, as a practical matter, to control many matters submitted to our shareholders for
approval, as well as our management and affairs. For example, these persons, if they choose to act together, could control
the  election  of  the  board  directors  and  the  approval  of  any  merger,  consolidation,  or  sale  of  all  or  substantially  all  our
assets. These shareholders may have interests that differ from those of other of our shareholders and conflicts of interest
may arise.

Provisions of our articles of association or Dutch corporate law might deter acquisition bids for us that might

be considered favorable and prevent or frustrate any attempt to replace our board.

Certain provisions of our articles of association may make it more difficult for a third party to acquire control of

us or effect a change in our board. These provisions include:

● staggered terms of our directors;
● a provision that our directors may only be removed at a general meeting of shareholders by a two-thirds majority

of votes cast representing more than half of the issued share capital of the Company; and

● a requirement that certain matters, including an amendment of our articles of association, may only be brought to

our shareholders for a vote upon a proposal by our board.

We do not expect to pay dividends in the foreseeable future.

We  have  not  paid  any  dividends  since  our  incorporation.  Even  if  future  operations  lead  to  significant  levels  of
distributable profits, we currently intend that earnings, if any, will be reinvested in our business and that dividends will not
be paid until we have an established revenue stream to support continuing dividends. Accordingly, shareholders cannot rely
on dividend income from our ordinary shares and any returns on an investment in our ordinary shares will likely depend
entirely upon any future appreciation in the price of our ordinary shares.

If we fail to maintain an effective system of internal controls, we may be unable to accurately report our results
of operations or prevent fraud or fail to meet our reporting obligations, and investor confidence and the market price of
our ordinary shares may be materially and adversely affected.

If we fail to maintain the adequacy of our internal control over financial reporting, we may not be able to conclude
on an ongoing basis that we have effective internal control over financial reporting. If we fail to maintain effective internal
control over financial reporting, we could experience material misstatements in our financial statements and fail to meet
our reporting obligations, which would likely cause investors to lose confidence in our reported financial information. This
could in turn limit our access to capital markets, harm our results of operations, and lead to a decline in the trading price of
our ordinary shares. Additionally, ineffective internal control over financial reporting could expose us to increased risk of
fraud or misuse of corporate assets and subject us to potential delisting from The Nasdaq Global Select Market, regulatory
investigations and civil or criminal sanctions. Our reporting and compliance obligations may place a significant strain on
our management, operational and financial resources and systems for the foreseeable future.

Risks for U.S. Holders

We have in the past qualified and in the future may qualify as a passive foreign investment company, which

may result in adverse U.S. federal income tax consequence to U.S. holders.

Based on our average value of our gross assets, our cash and cash equivalents as well as the price of our shares we
qualified as a passive foreign investment company (“PFIC”) for U.S. federal income tax for 2016 but not for 2017 through
2021. A corporation organized outside the United States generally will be classified as a PFIC for U.S. federal income tax
purposes in any taxable year in which at least 75% of its gross income is passive income or on average at least 50% of the
gross value of its assets is attributable to assets that produce passive income or are held to produce passive income. Passive
income for this purpose generally includes dividends, interest, royalties, rents and gains from commodities and securities
transactions.  Our  status  in  any  taxable  year  will  depend  on  our  assets  and  activities  in  each  year,  and  because  this  is  a
factual determination made annually after the end of each taxable year, there can be no assurance that we will continue to
qualify as a PFIC in future taxable years. The market value of our assets may be determined in large part by reference to
the  market  price  of  our  ordinary  shares,  which  is  likely  to  fluctuate,  and  may  fluctuate  considerably  given  that  market
prices of biotechnology companies have been especially volatile. If we were considered a PFIC for the current taxable year
or any future taxable year, a U.S. holder would be required to file annual information returns for such year, whether the
U.S. holder disposed of any ordinary shares or received any distributions in respect of ordinary shares during such year. In
certain circumstances a U.S. holder may be able to make certain tax elections that would lessen the adverse impact of PFIC
status;  however,  to  make  such  elections  the  U.S.  holder  will  usually  have  to  have  been  provided  information  about  the
company by us, and we do not intend to provide such information.

The  U.S.  federal  income  tax  rules  relating  to  PFICs  are  complex.  U.S.  holders  are  urged  to  consult  their  tax
advisors  with  respect  to  the  purchase,  ownership  and  disposition  of  our  shares,  the  possible  implications  to  them  of  us
being  treated  as  a  PFIC  (including  the  availability  of  applicable  election,  whether  making  any  such  election  would  be
advisable in their particular circumstances) as well as the federal, state, local and foreign tax considerations applicable to
such holders in connection with the purchase, ownership, and disposition of our shares.

Any U.S. or other foreign judgments may be difficult to enforce against us in the Netherlands.

Although we now report as a U.S. domestic filer for SEC reporting purposes, we are incorporated under the laws
of the Netherlands. Some of the members of our board and senior management reside outside the United States. As a result,
it may not be possible for shareholders to effect service of process within the United States upon such persons or to enforce
judgments  against  them  or  us  in  U.S.  courts,  including  judgments  predicated  upon  the  civil  liability  provisions  of  the
federal securities laws of the United States. In addition, it is not clear whether a Dutch court would impose civil liability on
us or any of our Board members in an original action based solely upon the federal securities laws of the United States
brought in a court of competent jurisdiction in the Netherlands.

The United States and the Netherlands currently do not have a treaty providing for the reciprocal recognition and
enforcement of judgments, other than arbitration awards, in civil and commercial matters. Consequently, a final judgment
for payment given by a court in the United States, whether or not predicated solely upon U.S. securities laws, would not
automatically  be  recognized  or  enforceable  in  the  Netherlands.  To  obtain  a  judgment  which  is  enforceable  in  the
Netherlands, the party in whose favor a final and conclusive judgment of the U.S. court has been rendered will be required
to file its claim with a court of competent jurisdiction in the Netherlands. Such party may submit to the Dutch court the
final judgment rendered by the U.S. court. If and to the extent that the Dutch court finds that the jurisdiction of the U.S.
court has been based on grounds which are internationally acceptable and that proper legal procedures have been observed,
the Dutch court will, in principle, give binding effect to the judgment of the U.S. court, unless such judgment contravenes
principles  of  public  policy  of  the  Netherlands.  Dutch  courts  may  deny  the  recognition  and  enforcement  of  punitive
damages  or  other  awards.  Moreover,  a  Dutch  court  may  reduce  the  amount  of  damages  granted  by  a  U.S.  court  and
recognize  damages  only  to  the  extent  that  they  are  necessary  to  compensate  actual  losses  or  damages.  Enforcement  and
recognition  of  judgments  of  U.S.  courts  in  the  Netherlands  are  solely  governed  by  the  provisions  of  the  Dutch  Civil
Procedure Code.

Therefore U.S. shareholders may not be able to enforce against us or our board members or senior management
who are residents of the Netherlands or countries other than the United States any judgments obtained in U.S. courts in
civil and commercial matters, including judgments under the U.S. federal securities laws.

The rights and responsibilities of our shareholders and directors are governed by Dutch law and differ in some

important respects from the rights and responsibilities of shareholders under U.S. law.

Although  we  now  report  as  a  U.S.  domestic  filer  for  SEC  purposes,  our  corporate  affairs  are  governed  by  our
articles of association and by the laws governing companies incorporated in the Netherlands. The rights of our shareholders
and  the  responsibilities  of  members  of  our  board  under  Dutch  law  are  different  than  under  the  laws  of  some  U.S.
jurisdictions. In the performance of their duties, our board members are required by Dutch law to consider the interests of
uniQure,  its  shareholders,  its  employees,  and  other  stakeholders  and  not  only  those  of  our  shareholders  (as  would  be
required under the law of most U.S. jurisdictions). As a result of these considerations our directors may take action that
would be different than those that would be taken by a company organized under the law of some U.S. jurisdictions.

Item 2.  Properties.

Lexington, Massachusetts / United States

We  operate  an  83,998  square  feet  GMP  qualified  manufacturing  facility  that  we  lease  in  Lexington,
Massachusetts. In November 2018, we extended and expanded the facility by leasing an additional 30,655 square feet (as
from  June  1,  2019  onwards)  of  the  same  building.  The  expanded  and  extended  lease  for  the  facility  terminates  in  June
2029, and subject to the provisions of the lease, may be renewed for two subsequent five-year terms.

In  December  2021,  we  entered  into  a  new  lease  for  an  additional  facility  in  Lexington,  Massachusetts,  United
States of approximately 13,501 square feet of space. The lease is expected to commence in the second half of 2022, is set
for seven years starting from the rent commencement date and is non-cancellable. The lease is renewable for one five-year
term.

In February 2022, we also entered into a new lease for an additional facility in Lexington, Massachusetts, United
States of approximately 12,716 square feet. The lease is expected to commence in the second half of 2022 and is set for a
non-cancellable period of seven years and four months. The lease is renewable for one five-year term.

Amsterdam / The Netherlands

In 2016, we entered into leases for a total of approximately 111,000 square feet facility in Amsterdam. The lease

for this facility terminates in 2032, with an option to extend in increments of five-year periods.

In December 2017, we entered into an agreement to sub-lease three of the seven floors of our Amsterdam facility
for a ten-year term ending on December 31, 2027, with an option for the sub-lessee to extend until December 31, 2031 as
well as an option that has expired to break the lease prior to December 31, 2020 subject to the lessee paying a penalty and
breaking certain financial covenants. In February 2020, we amended the sub-lease agreement to take back one of the three
floors effective March 1, 2020.

In February 2021, we commenced the expansion of our Amsterdam site to build additional laboratories to support
the expansions of our research and development activities as well the construction of a cleanroom designed to be capable
of manufacturing cGMP materials at a 500-liter scale.

In  May  2021,  we  entered  into  a  sublease  agreement  to  let  an  additional  approximately  1,080  square  meters  of
office space to accommodate the hiring of additional full-time employees. The lease expires in October 2028 and includes
an option to break the lease on October 31, 2023.

We believe that our existing facilities, combined with the new facilities in Lexington, are adequate to meet current

needs and that suitable alternative spaces will be available in the future on commercially reasonable terms.

Item 3.  Legal Proceedings.

On  or  about  February  22,  2021,  Dr.  Konstantinova,  VectorY  B.V.,  and  Forbion  International  Management  B.V.
commenced  a  summary  proceeding  in  the  Netherlands  primarily  seeking  an  order:  (i)  allowing  VectorY  and  Dr.
Konstantinova to continue their employment relationship; (ii) suspending the non-competition agreement between uniQure
biopharma  B.V.  and  Dr.  Konstantinova;  and  (iii)  precluding  any  monetary  penalties  pursuant  to  that  non-competition
agreement. The complaint also sought payment of the costs of legal proceedings and a monetary monthly payment to Dr.
Konstantinova in lieu of a promise by uniQure biopharma B.V. to release Dr. Konstantinova from her obligations under the
non-competition agreement.

On April 16, 2021, we settled all matters related to the dispute described above (the “Settlement”). In connection
with the Settlement, we received, among other things, preference shares in VectorY representing 5% of the fully diluted
share capital in VectorY. In addition, we and certain related Forbion entities entered into a Cooperation Agreement.

Under the terms of the Cooperation Agreement, we and the Forbion entities agreed to certain non-disparagement

provisions, and the Forbion entities agreed, among other things, for a period of two years from April 16, 2021:

and nominated by the Board for re-election; (2) against any nominees to serve on the Board who have
not been recommended by the Board, and (3) with respect to all other matters, other than certain defined
exempt matters, in accordance with the Board’s recommendations as identified in our notice of general
meeting or any supplement thereto.

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

Our  ordinary  shares  are  listed  on  the  Nasdaq  Global  Select  Market  under  the  symbol  “QURE”.  We  have  never
paid any cash dividends on our ordinary shares, and we do not anticipate paying cash dividends in the foreseeable future.
We anticipate that we will retain all earnings, if any, to support operations and to finance the growth and development of
our business for the foreseeable future.

Unregistered Sales of Equity Securities

During the period covered by this Annual Report on Form 10-K, we have not issued any securities that were not

registered under the Securities Act.

Issuer Share Repurchases

We did not make any purchases of our ordinary shares during the year ended December 31, 2021. Our affiliates

made purchases of our ordinary shares as described in “Unregistered Sales of Equity Securities” above.

Holders

As  of  February  23,  2022,  there  were  approximately  seven  holders  of  record  of  our  ordinary  shares.  The  actual
number of shareholders is greater than this number of record holders, and includes shareholders who are beneficial owners,
but whose shares are held in street name by brokers and other nominees. This number of holders of record also does not
include shareholders whose shares may be held in trust by other entities.

Share Performance Graph

The following graph compares the performance of our ordinary shares (“QURE”) for the periods indicated with
the performance of the NASDAQ Composite Index (“˄IXIC”) and the Nasdaq biotechnology index (“˄NBI”). This graph
assumes an investment of $100 after market close on December 31, 2016 in each of our ordinary shares, the NASDAQ
Composite  Index,  and  the  NASDAQ  Biotechnology  Index,  and  assumes  reinvestment  of  dividends,  if  any.  The
performance of our ordinary shares shown on the graph below is not necessarily indicative of the future performance of our
ordinary shares. This graph is not “soliciting material”, is not deemed “filed” with the SEC and is not to be incorporated by

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

The  following  Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations
(“MD&A”)  is  intended  to  help  the  reader  understand  our  results  of  operations  and  financial  condition.  This  MD&A  is
provided as a supplement to, and should be read in conjunction with, our audited consolidated financial statements and the
accompanying notes thereto and other disclosures included in this Annual Report on Form 10-K, including the disclosures
under “Risk Factors”. Our consolidated financial statements have been prepared in accordance with generally accepted
accounting principles in the United States (“U.S. GAAP”) and unless otherwise indicated are presented in U.S. dollars.

Except for the historical information contained herein, the matters discussed in this MD&A may be deemed to be

Overview

We  are  a  leader  in  the  field  of  gene  therapy  and  seek  to  deliver  to  patients  suffering  from  rare  and  other
devastating diseases single treatments with potentially curative results. We are advancing a focused pipeline of innovative
gene therapies, including product candidates for the treatment of hemophilia B, which effective May 6, 2021, we licensed
to  CSL  Behring  pursuant  to  the  CSL  Behring  Agreement  (as  defined  below),  and  Huntington’s  disease.  We  believe  our
technology platform and manufacturing capabilities provide us distinct competitive advantages, including the potential to
reduce development risk, cost, and time to market. We produce our AAV-based gene therapies in our own facilities with a
proprietary, commercial-scale, cGMP-compliant, manufacturing process. We believe our Lexington, Massachusetts-based
facility is one of the world’s most versatile gene therapy manufacturing facilities.

Business developments

Below is a summary of our recent significant business developments:

Acquisition of Corlieve Therapeutics

On June 21, 2021, we entered into a SPA to acquire all of outstanding ordinary shares of Corlieve. The transaction
closed on July 30, 2021. On the Acquisition Date, we acquired 97.7% of the outstanding ordinary shares of Corlieve in
return for EUR 44.9 million ($53.3 million as of the Acquisition Date). As contractually required in the SPA, we acquired
the  remaining  outstanding  ordinary  shares  on  February  9  2022.  We  recorded  a  liability  related  to  these  Mandatorily
Redeemable Shares for an amount of EUR 0.7 million ($0.9 million) as of the Acquisition Date. We financed the Corlieve
Transaction from cash on hand.

77

Table of Contents

In addition to the payments to acquire 100% of the outstanding ordinary shares Corlieve’s former and remaining
shareholders  are  eligible  to  receive  up  to  EUR  35.8  million  (or  $40.6  million  as  of  December  31,  2021)  upon  the
achievement of development milestones through Phase I/II and EUR 143.1 million (or $162.3 million as of December 31,
2021) upon the achievement of milestones associated with Phase III development and obtaining approval to commercialize
AMT-260  in  the  United  States  of  America  and  the  European  Union.  We  may  elect  to  pay  up  to  25%  of  such  milestone
payments through the issuance of our ordinary shares. We recorded a EUR 20.2 million ($24.0 million) liability related to
these contingent consideration payments as of the Acquisition Date.

Total consideration of EUR 65.8 million ($78.1 million), which consisted of the cash paid upon the Acquisition
Date,  the  payment  for  the  Mandatorily  Redeemable  Shares  and  the  contingent  consideration  payments,  was  allocated  to
identifiable  intangible  assets  related  to  the  IPR&D  Intangible  Asset.  The  IPR&D  Intangible  Asset’s  fair  value  has  been
determined at EUR 53.6 million ($63.6 million) as of the Acquisition Date. We also recognized a EUR 13.4 million ($15.9
million as of the Acquisition Date) deferred tax liability in relation to this IPR&D Intangible Asset. The total consideration
in excess of the net assets acquired was EUR 23.9 million ($28.4 million as of the Acquisition Date) and was allocated to
goodwill.

CSL Behring commercialization and license agreement

On  June  24,  2020,  uniQure  biopharma  B.V.,  a  wholly  owned  subsidiary  of  uniQure  N.V.,  entered  into  the  CSL
Behring Agreement with CSL Behring pursuant to which CSL Behring will receive exclusive global rights to etranacogene
dezaparvovec, the Product.

The  transaction  became  fully  effective  on  May  6,  2021,  one  day  after  the  waiting  period  under  the  HSR  Act

expired on May 5, 2021.

CSL Behring is responsible for the development and commercialization of the Product. We agreed to complete the
validation  of  the  current  manufacturing  process  as  well  as  to  the  development  and  validation  of  a  next  generation
manufacturing process. We will be entitled to receive a development milestone payment if we complete these activities in
accordance with an agreed development plan and timeline. CSL Behring is responsible for global regulatory submissions
and commercialization requirements for the Product.  Certain clinical development and regulatory activities performed by
us are reimbursed by CSL Behring.

On the Signing Date, we and CSL Behring also entered into a development and commercial supply agreement,
pursuant to which, among other things, we will supply the Product to CSL Behring at an agreed-upon price commensurate
with the SSP. We will be responsible to supply the Product until such time that these capabilities may be transferred to CSL
Behring or its designated contract manufacturing organization.

Following  the  closing  of  the  CSL  Behring  Agreement,  we  recorded  $462.4  million,  including  a  $450.0  million
upfront  cash  payment,  as  license  revenue.  Upon  closing,  we  contractually  owed  to  our  licensors  $15.5  million  of  the
upfront payment received from CSL Behring.  

We are eligible to receive more than $0.3 billion in regulatory, development, and first commercial sale milestones,
$1.3 billion in additional commercial milestones, and tiered double-digit royalties of up to a low-twenties percentage of net
product  sales  arising  from  the  collaboration.  As  of  December  31,  2021,  we  accrued  revenue  of  $55.0  million  related  to
milestone payments we expect to receive under the CSL Behring Agreement following the submissions of a BLA to the
FDA and a MAA to the EMA, which are expected to be submitted during the first half of 2022.

Hemophilia B program – Etranacogene dezaparvovec (AMT-061)

In  June  2018,  we  initiated  our  Phase  III  HOPE-B  pivotal  trial  of  etranacogene  dezaparvovec.  The  trial  is  a
multinational, multi-center, open-label, single-arm study to evaluate the safety and efficacy of etranacogene dezaparvovec.

In March 2020, we completed dosing of the 54 patients in the HOPE-B trial. Following a pre-BLA submission
meeting with the FDA on June 4, 2021, the primary endpoint has been determined as a non-inferiority analysis of ABR at
18-months after the administration (approximately 52 weeks after steady-state is achieved).

78

Table of Contents

On December 9, 2021, we announced the achievement of the pre-specified primary endpoint of non-inferiority in
annualized  bleeding  rate  (“ABR”)  18-months  following  administration  compared  to  baseline  Factor  IX  (“FIX”)
prophylactic  therapy  in  the  HOPE-B  Study.  The  study  also  successfully  achieved  a  secondary  endpoint  demonstrating
statistical superiority in reduction of ABR compared to baseline FIX prophylactic therapy. ABR for all bleeds after stable
FIX  expression,  assessed  at  18  months,  was  1.51  compared  with  the  ABR  of  4.19  for  the  lead-in  period  of  at  least  six
months, achieving the primary non-inferiority endpoint and a secondary superiority endpoint (p=0.0002) in the HOPE-B
Study. ABR for investigator-adjudicated FIX-treated bleeds was 0.83 compared with lead-in ABR of 3.65 (p<0.0001).  All
participants continued to demonstrate durable, sustained increases in FIX activity at 18-months post-infusion with a mean
FIX  activity  of  36.9  percent  of  normal,  as  measured  by  a  one-stage  activated  partial  thromboplastin  time-based  (“aPTT-
based”) clotting assay, compared to a mean FIX activity of  39.0 percent of normal at 26-weeks of follow-up. Etranacogene
dezaparvovec was generally well-tolerated with over 80% of adverse events considered mild.

Huntington’s disease program (AMT-130)

AMT-130  is  our  novel  gene  therapy  candidate  for  the  treatment  of  Huntington’s  disease.  AMT-130  utilizes  our
proprietary, gene-silencing miQURE platform and incorporates an AAV vector carrying a miRNA specifically designed to
silence the huntingtin gene and the potentially highly toxic exon 1 protein fragment. We are currently conducting a Phase
I/II  clinical  trial  for  AMT-130  in  the  U.S.  and  a  Phase  Ib/II  study  in  the  EU.  Together,  these  studies  are  intended  to
establish safety, proof of concept, and the optimal dose of AMT-130 to take forward into Phase III development or into a
confirmatory study should an accelerated registration pathway be feasible. AMT-130 has received Orphan Drug and Fast
Track designations from the FDA and Orphan Medicinal Product Designation from the EMA.

On April 5, 2021, we announced the completion of enrollment of the low-dose cohort of the U.S. Phase I/II study
of AMT-130.  The low-dose cohort includes 10 patients, of which six patients received treatment with AMT-130 and four
patients  received  Sham  surgery.  The  U.S.  Phase  I/II  clinical  trial  is  a  randomized,  controlled,  double-blinded,  dose-
escalation study of AMT-130.

On June 13, 2021, we announced the enrollment of the first two patients in the high-dose cohort of a U.S. Phase
I/II study. The high- dose cohort is planned to include 16 patients, of which 10 patients will receive treatment with AMT-
130  and  six  patients  will  receive  Sham  surgery.  The  initiation  of  patient  enrollment  in  the  high-dose  cohort  followed  a
meeting of the trial’s independent DSMB that reviewed safety data for the fully enrolled first cohort of 10 patients.

On December 16, 2021, we announced initial 12-month observations on the first four patients enrolled in the low-
dose cohort of the U.S. Phase I/II study. Two of the four enrolled patients received AMT-130, and two patients received
Sham surgery as a control. AMT-130 was generally well tolerated in the treated patients, with no serious adverse events
related  to  AMT-130.  NfL,  a  biomarker  of  injury  in  the  brain,  increased  as  expected  immediately  following  the  surgical
procedure  and  returned  to  baseline  in  the  treated  patients.  NfL  remained  relatively  constant  in  the  two  untreated  control
patients. Structural magnetic resonance imaging did not reveal any clinically meaningful safety findings in either treated or
control patients at one year of follow-up. Measurements of total and mutant HTT protein in the cerebral spinal fluid of the
four  patients  were  highly  variable  and  inconclusive.  As  of  December  31,  2021,  19  patients  have  been  enrolled  in  the
clinical trial to date, including nine of 16 in the high-dose cohort.

Also on December 16, 2021, we announced the initiation of patient screening in our 15 patient, open-label, Phase
Ib/II study of AMT-130 in the EU, as well our plans to initiate a third cohort in the ongoing U.S. Phase I/II clinical trial.
The third cohort, which will include up to 18 additional randomized patients receiving the higher dose, will explore the use
of alternative stereotactic navigation systems to simplify placement of catheters for infusions of AMT-130.

BMS collaboration

We and Bristol-Myers Squibb (“BMS”) entered into a collaboration and license agreement in May 2015 (“BMS
CLA”).  BMS  had  initially  designated  four  Collaboration  Targets  in  2015  and  in  accordance  with  the  terms  of  the  BMS
CLA could have designated a fifth to tenth Collaboration Target.

In February 2019, BMS requested a one-year extension of the initial research term. In April 2019, following an
assessment of the progress of this collaboration and our expanding proprietary programs, we notified BMS that we did not
intend  to  agree  to  an  extension  of  the  initial  research  term.  Accordingly,  the  initial  four-year  research  term  under  the
collaboration terminated on May 21, 2019.

Table of Contents

On December 1, 2020, we and BMS amended the BMS CLA (“amended BMS CLA”). For a period of one-year
from the effective date of the amended BMS CLA, BMS was able to replace up to two of the four active Collaboration
Targets with two new targets in the field of cardiovascular disease. We are entitled to receive up to $217.0 million for each
of the four Collaboration Targets if defined milestones are achieved, as well as royalties on net sales associated with any
Collaboration  Target.  On  December  17,  2020,  BMS  designated  one  of  the  four  Collaboration  Targets  as  a  candidate  to
advance into IND-enabling studies entitling us to receive a $4.4 million research milestone payment. We recorded the $4.4
million as License Revenue in the twelve-month period ended December 31, 2020.

The  amended  BMS  CLA  did  not  extend  the  initial  research  term.  BMS  may  place  purchase  orders  to  provide
limited services primarily related to analytical and development efforts in respect of the four Collaboration Targets. BMS
may request such services for a period not to exceed the earlier of (i) the completion of all activities under a Research Plan
and  (ii)  either  (A)  three  years  after  the  last  replacement  target  has  been  designated  by  BMS  during  the  one-year
replacement  period  following  the  amended  BMS  CLA  effective  date  or  (B)  three  years  if  no  replacement  targets  are
designated during this one-year period and BMS continues to reimburse us for these services.

 For as long as any of the four Collaboration Targets are being advanced, BMS may place a purchase order to be
supplied with research, clinical and commercial supplies. Subject to the terms of the amended BMS CLA, BMS has the
right  to  terminate  the  research,  clinical  and  commercial  supply  relationships,  and  has  certain  remedies  for  failures  of
supply, up to and including technology transfer for any such failure that otherwise cannot be reasonably resolved. Both we
and  BMS  may  agree  to  a  technology  transfer  of  manufacturing  capabilities  pursuant  to  the  terms  of  the  amended  BMS
CLA.

We have agreed to certain restrictions on our ability to work independently of the collaboration, either directly or
indirectly through any affiliate or third party, on certain programs that would be competitive with a Collaboration Target.
We have agreed to indication exclusivity for the current four Collaboration Targets. BMS may add or change the exclusive
indications  in  the  process  of  replacing  Collaboration  Targets  as  described  above.  We  can  opt  out  of  the  indication
exclusivity by giving up certain economic rights under the amended BMS CLA for each such indication that is affected by
us  opting  out.  If  we  opt  out  of  an  exclusive  indication,  we  could  pursue  other  targets  for  such  indication  other  than  a
Collaboration Target.

The amended BMS CLA also terminated two warrants to increase BMS ownership in the Company up to 19.9%
through  purchasing  a  specific  number  of  our  ordinary  shares  following  the  designation  of  a  seventh,  and  a  tenth
Collaboration Target, respectively. We and BMS agreed that upon the consummation of a change of control transaction of
uniQure that occurs prior to the earlier of (i) December 1, 2026 and (ii) BMS’ delivery of a target cessation notice for all
four  Collaboration  Targets,  uniQure  (or  its  third  party  acquirer)  shall  pay  to  BMS  a  one-time,  non-refundable,  non-
creditable cash payment of $70.0 million, provided that (x) if $70.0 million is greater than five percent of the net proceeds
(as contractually defined) from such change of control transaction, the payment shall be an amount equal to five percent of
such net proceeds, and (y) if $70.0 million is less than one percent of such net proceeds, the change of control payment
shall be an amount equal to one percent of such net proceeds. We have not consummated any change of control transaction
as of December 31, 2021 that would obligate us to make a payment to BMS.

The  amended  BMS  CLA  did  not  change  any  of  the  provisions  of  the  Investor  Agreement  with  BMS  that  we
entered  into  in  2015.  We  have  granted  BMS  certain  registration  rights  that  allow  BMS  to  require  us  to  register  our
securities beneficially held by BMS under the U.S. Securities Exchange Act of 1934, as amended (“Exchange Act”). BMS
may make up to two such demands for us to register the shares, provided that we may deny such demand if (i) the market
value  of  the  shares  to  be  registered  is  less  than  $10.0  million  (provided  however,  if  BMS  holds  less  than  $10.0  million
worth of our shares, we must comply with their demand for registration), (ii) we certify to BMS that we plan to effect a
registration within 120 days of their demand or we are engaged in a transaction that would be required to be disclosed in a
registration statement and that is not reasonably practicable to be disclosed at that time, or (iii) we have already effected
one registration statement within the twelve months preceding BMS’s demand for registration. In addition, independent of
their  demand  registration  rights,  upon  the  occurrence  of  certain  events,  we  must  also  provide  BMS  the  opportunity  to
include their ordinary shares in any registration statement that we effect.

We  also  continue  to  grant  BMS  certain  information  rights  under  the  Investor  Agreement,  although  these

requirements may be satisfied by our public filings required by U.S. securities laws.

Table of Contents

BMS also continues to be subject to a lock up pursuant to the Investor Agreement for as long as BMS holds more
than 4.9% of our ordinary shares (as of December 31, 2021 BMS holds 5.2%). Without our prior consent, BMS may not
sell or dispose any of its current ordinary shares.

The Investor Agreement also continues to require BMS to vote all of our ordinary shares it beneficially holds in
favor of all items on the agenda for the relevant general meeting of shareholders of our company as proposed on behalf of
our  company,  unless,  in  the  context  of  a  change  of  control  or  similar  transaction,  BMS  has  itself  made  an  offer  to  our
company or our board in connection with the transaction that is the subject of the vote, in which case it is free to vote its
shares at its discretion. This voting provision will terminate upon the later of the date on which BMS no longer beneficially
owns  at  least  4.9%  of  our  outstanding  ordinary  shares,  the  closing  of  a  transaction  that  provides  BMS  exclusive  and
absolute discretion to vote our shares it beneficially holds, or the termination of the amended BMS CLA for breach by us.

We have recognized license revenues associated with the amortization of the non-refundable upfront payment and
target  designation  fees  we  received  from  BMS  in  accordance  with  the  BMS  CLA.  We  evaluated  our  outstanding
performance  obligation  following  the  amendment  of  the  BMS  CLA  on  December  1,  2020  and  determined  that  our
remaining  performance  obligation  related  to  license  revenues  is  immaterial.  We  updated  our  measure  of  progress
accordingly and amortized the remaining balance of unrecognized revenue as of November 30, 2020. We recorded no such
license  revenue  for  the  year  ended  December  31,  2021.  In  accordance  with  the  amended  BMS  CLA,  we  continue  to  be
eligible  to  receive  research,  development,  and  regulatory  milestone  payments  as  well  as  sales  milestone  payments  and
royalties for each of the four active Collaboration Targets if defined milestones are achieved in relation to the license to our
technology and know-how. We will recognize revenue from these payments when earned or as sales occur.

We  recognize  collaboration  revenues  associated  with  Collaboration  Target-specific  pre-clinical  analytical
development  and  process  development  activities  that  are  reimbursable  by  BMS  under  the  BMS  CLA  and  the  amended
BMS  CLA  as  well  as  other  related  agreements.  Collaboration  revenue  related  to  these  contracted  services  is  recognized
when performance obligations are satisfied.

Financing

As of December 31, 2020, a $35.0 million term loan was outstanding in accordance with the Second Amended

and Restated Loan and Security Agreement (the “2018 Amended Facility”) between us and Hercules.

On January 29, 2021, we and Hercules entered into the 2021 Amended Facility. Pursuant to the 2021 Amended
Facility,  Hercules  agreed  to  an  additional  Facility  of  $100.0  million  (“Tranche  B”)  increasing  the  aggregate  principal
amount of the term loan facilities from $35.0 million to up to $135.0 million. On January 29, 2021, we drew down $35.0
million of the Tranche B. Advances under Tranche B bore interest at a rate equal to the greater of (i) 8.25% or (ii) 8.25%
plus the prime rate, less 3.25% per annum. The principal balance of $70.0 million and all accrued but unpaid interest on
advances under Tranche B was due on June 1, 2023. The back-end fee in respect of advances under the 2021 Amended
Facility  ranged  from  1.65%  to  6.85%,  depending  on  the  repayment  date.  In  addition  to  Tranche  B,  the  2021  Amended
Facility  also  extended  the  interest  only  payment  period  of  the  previously  funded  $35.0  million  term  loan  (“Tranche  A”)
from January 1, 2022 to June l, 2023.

On  December  15,  2021,  we  and  Hercules  amended  and  restated  the  2021  Amended  Facility  (“2021  Restated
Facility”).  Pursuant  to  the  2021  Restated  Facility,  Tranche  A  and  Tranche  B  of  the  2021  Amended  Facility  with  a  total
outstanding balance of $70.0 million were consolidated into one tranche with a total commitment of $100.0 million. We
drew down an additional $30.0 million, resulting in total principal outstanding as of December 31, 2021 of $100.0 million.
The 2021 Restated Facility extended the loan’s maturity date from June 1, 2023 until December 1, 2025. The interest-only
period is extended from January 1, 2023 to December 1, 2024, or December 1, 2025 if, prior to June 30, 2024, either (a) the
BLA for AMT-061 is approved by the FDA or (b) AMT-130 is advanced into a pivotal trial. The interest rate is adjustable
and is the greater of (i) 7.95% and (ii) 7.95% plus the prime rate less 3.25% per annum. Under the 2021 Restated Facility,
we  owe  a  back-end  fee  of  4.85%  of  the  outstanding  debt.  We  are  required  to  repay  the  facility  in  equal  monthly
installments of principal and interest between the end of the interest-only period and the maturity date. We continue to owe
a $2.5 million back-end fee related to the 2021 Amended Facility which is due on June 1, 2023.

On March 1, 2021, we entered into a Sales Agreement with SVB Leerink LLC (“SVB Leerink”) with respect to an
at-the-market  (“ATM”)  offering  program,  under  which  we  may,  from  time  to  time  in  our  sole  discretion,  offer  and  sell
through SVB Leerink, acting as agent, our ordinary shares, up to an aggregate offering price of $200.0 million. We pay
SVB Leerink a commission equal to 3% of the gross proceeds of the sales price of all ordinary shares sold through it as a
sales agent under the Sales Agreement.

In March and April of 2021, we issued 921,730 ordinary shares at a weighted average price of $33.52 per ordinary

share, with net proceeds of $29.6 million, after deducting underwriting discounts and net of offering expenses.

Covid pandemic

The coronavirus disease (“Covid”) caused by the severe acute respiratory syndrome coronavirus 2 (“Sars-CoV 2
virus”)  was  characterized  as  a  pandemic  by  the  World  Health  Organization  (“WHO”)  on  March  11,  2020.  Since  then,
various, potentially more infectious, variants of the Sars-CoV 2 virus causing Covid have been identified.

Throughout the pandemic, we have been implementing measures to address the impact of Covid on our business.
We  have  implemented  a  series  of  protocols  governing  the  operations  of  our  Lexington  facility  to  comply  with  the
requirements  of  the  various  orders  and  guidance  from  the  Commonwealth  of  Massachusetts  and  other  related  orders,
guidance, laws, and regulations. We continue to monitor local government rules and recommendations and office protocols
will  be  aligned  with  these  rules  and  recommendations.  Accordingly,  we  had  mandated  a  work-from-home  policy  since
March  2020  for  all  non-essential  employees  at  our  Amsterdam  and  Lexington  facilities  and  had  implemented  additional
protocols for our essential employees.

Effective  May  29,  2021,  Massachusetts  lifted  all  industry  restrictions,  with  the  exceptions  of  remaining  face-
covering requirements for all public and private transportation systems and facilities housing vulnerable populations, and
capacity has been increased to 100% for all industries. Furthermore, the state of emergency was lifted on June 15, 2021.
Implementation of adequate cleaning and hygiene protocols are still encouraged. We have implemented a mandatory Covid
PCR testing protocol in our Lexington facility effective February 2021 that requires employees to have tested negative for
Covid prior to entering the facility. Effective April 2021, we implemented a policy whereby no employee or contractor may
enter the Lexington facility unless they are either: (i) fully vaccinated; or (ii) have taken an approved test for Covid and
obtained a negative result. All employees that are not essential employees, however, will continue to work remotely until at
least June 30, 2022 to reduce the spread of Covid within the facility. As a result, we have been operating our Lexington
facility with attendance significantly below 100% capacity.

From  November  1,  2021,  employees  were  expected  to  be  required  to  work  on-site  at  our  Amsterdam  office  at
least  one  day  a  week  under  our  new  remote  working  policy.  However,  the  Company  adjusted  the  policy  for  Dutch
government  updates.  Between  November  12,  2021  and  the  filing  date  of  this  Form  10-K  the  Dutch  government
continuously updated the Covid-related measures to mitigate the impact of the latest Covid variant. We continue to comply
with  these  measures,  which  amongst  others  is  recommended  to  work  from  the  office  no  more  than  half  the  time  for
nonessential employees.

The broader implications of Covid, including the implications from the various variants, on our results of
operations and overall financial performance remain uncertain. We have experienced increased lead times in the delivery of
equipment and disposables that we use to manufacture materials for our various programs. Currently, these have not
materially impacted our development timelines and we continue to adapt to the current environment to minimize the effect
to our business. However, we may experience more pronounced disruptions in our operations in the future.

Related party transaction

On  December  1,  2020,  we  and  BMS  entered  into  the  amended  BMS  CLA.  All  transactions  subsequent  to  the

effective date of the amended BMS CLA are considered to no longer be with a related party.

As  of  December  31,  2021,  we  had  cash  and  cash  equivalents  of  $556.3  million  (December  31,  2020:
$244.9 million). We had a net income of $329.6 million in 2021, and a net loss of $125.0 million in 2020 and a net loss of
$124.2 million in 2019. As of December 31, 2021, we had an accumulated deficit of $455.1 million (December 31, 2020:
$784.7  million).  We  recorded  net  income  in  the  year  ended  December  31,  2021  as  a  result  of  closing  the  CSL  Behring
transaction on May 6, 2021.

We anticipate that our expenses will increase substantially as we:
● advance the clinical development of AMT-130 for our Huntington’s disease gene therapy program;
● advance  multiple  research  programs  related  to  gene  therapy  candidates  targeting  liver-directed  and  CNS

diseases;

● continue  to  expand  our  employee  base  to  support  research  and  development,  as  well  as  general  and

administrative functions;

● acquire or in-license rights to new therapeutic targets or product candidates;
● continue to expand, enhance and optimize our technology platform, including our manufacturing capabilities,

next-generation viral vectors and promoters, and other enabling technologies;

● maintain, expand, and protect our intellectual property portfolio, including in-licensing additional intellectual

property rights from third parties; and

● make potential future milestone payments related to the acquisition of Corlieve, if any.

See “Results of Operations” below for a discussion of the detailed components and analysis of the amounts above.

Critical Accounting Policies and Estimates

In preparing our consolidated financial statements in accordance with U.S. GAAP and pursuant to the rules and
regulations promulgated by the SEC we make assumptions, judgments and estimates that can have a significant impact on
our  net  income/loss  and  affect  the  reported  amounts  of  certain  assets,  liabilities,  revenue  and  expenses,  and  related
disclosures. On an ongoing basis, we evaluate our assumptions, estimates and judgments, including those related to what
we believe to be our critical accounting policies.

We  base  our  assumptions,  judgments  and  estimates  on  historical  experience  and  various  other  factors  that  we
believe  to  be  reasonable  under  the  circumstances,  the  results  of  which  form  the  basis  for  making  judgments  about  the
carrying values of assets and liabilities that are not clear from other sources. Actual results may differ from these estimates
under  different  assumptions,  judgments  or  estimates.  We  also  discuss  our  critical  accounting  estimates  with  the  Audit
Committee of our Board of Directors.

We consider the following to be our critical accounting policies and estimates:

● ASC  805  Business  Combinations  in  relation  to  the  IPR&D  Intangible  Asset  and  Contingent

Consideration recorded in relation to the Corlieve business combination;

● ASC 606 Revenue from Contracts with Customers as it relates to the recognition of revenue including

the CSL Behring milestones in relation to the CSL Behring Agreements;

● ASC 740 Income Taxes as it relates to the Dutch valuation allowance and the U.S. valuation allowance;

 and

● ASC  606  Revenue  from  Contracts  with  Customers  as  it  relates  to  recognition  of  License  Revenue  in

relation to amended BMS CLA.

Table of Contents

Business combination

The  preparation  of  our  consolidated  financial  statements  for  the  year  ended  December  31,  2021,  required  us  to

analyze the accounting treatment for the Corlieve Transaction.

In connection with this analysis, we first applied a screen test to determine if substantially all of the fair value of
the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. We analyzed
whether the acquired inputs and processes that have the ability to create outputs would meet the definition of a business
and determined that the screen test was not met. In the event the screen test had been met, we would have been required to
account for the Corlieve Transaction as an asset acquisition. In this case, among others, we would not have recorded any
goodwill  and  expensed  all  identifiable  intangible  assets  without  alternative  future  use  in  accordance  with  ASC  805,
Business Combinations.

We identified various licenses that combined with the results of the research and development activities conducted
in relation to AMT-260 since formation of Corlieve in 2019 constitute an IPR&D Intangible Asset. The IPR&D Intangible
Asset was measured at its fair value as of the Acquisition Date. The fair value of EUR 53.6 million ($63.6 million) of the
IPR&D Intangible Asset accounted for 83.4% of the identifiable assets included within the screen test as of the Acquisition
Date.

We calculated the fair value of the IPR&D Intangible Asset using a present value model based on expected cash
flows. Estimating the amounts and timing of cash flows required to complete the development of AMT-260 as well as net
sales, cost of goods sold, and sales and marketing costs involved considerable judgment and uncertainty. The expected cash
flows are materially impacted by the probability of successfully completing the various stages of development (i.e., dosing
of first patient in clinical trial, advancing into late-stage clinical development and obtaining approval to commercialize the
product candidate) as well as the weighted average cost of capital of 10.4% used to discount the expected cash flows.

We developed the estimated probabilities of successfully completing the various stages of development using data

from external studies regarding average likelihoods of completing these stages of development. We increased the
probability for the TLE-program to advance into clinical development derived from such external studies from 33% to
40%. Following the completion of certain studies management in late October 2021 designated a lead candidate for the
program and based on data from external studies subsequently increased the likelihood to advance into clinical
development to 55%. Application of this probability as of the Acquisition Date would have changed the outcome of the
screen test and we would have been required to treat the Corlieve Transaction as an asset acquisition. If all other
assumptions and estimates remained unchanged this would have required us to expense any identifiable intangible assets
without alternative future use. However, the outcome of the screen test would not have been altered for as long as the
probability of advancing into clinical development remained below 43%.

We derived the weighted average cost of capital of 10.4% from external market data for a selected peer group of
companies.  We  included  a  0.2%  country  risk  premium  related  to  the  European  markets  in  our  weighted  average  cost  of
capital. Not including this risk premium would not have changed the outcome of the screen test. Changing the outcome of
the screen test would have required a reduction of the weighted average cost of capital by 0.5%. This would have required
us to expense all identifiable intangible assets without an alternative future use.

The determination of the fair values of assets acquired and liabilities assumed has been completed as of December
31, 2021. The IPR&D Intangible Asset is accounted for as indefinite-lived intangible asset and is measured at the fair value
of the incomplete research project acquired as of the Acquisition Date. The IPR&D Intangible Asset is considered to be
indefinite-lived  until  the  completion  or  abandonment  of  the  associated  research  and  development  efforts  and  is  not
amortized. If and when development is complete, which generally occurs when regulatory approval to market a product is
obtained,  the  associated  assets  would  be  deemed  finite-lived  and  would  then  be  amortized  based  on  an  estimate  of  its
remaining useful life. In case of abandonment, the IPR&D Intangible Asset would be written-off.

As  of  the  Acquisition  Date  we  recorded  contingent  consideration  related  to  amounts  potentially  payable  to
Corlieve’s former shareholders. The amounts payable in accordance with the SPA are contingent upon realization of certain
milestones  associated  with  the  TLE  research  program.  Contingent  consideration  was  measured  at  fair  value  at  the
Acquisition  Date  with  changes  in  fair  value  recognized  in  the  consolidated  statements  of  operations  in  research  and
development expenses.

Table of Contents

Changes in contingent consideration can result from changes in the assumed achievement and timing of estimated

milestones and the discount rate used to estimate the fair value of the liability:

● We believe that as of December 31, 2021 it is not reasonably possible that changes in market interest rate
or our credit profile would change the discount rate in a manner that would result in a material change of
the fair value of the contingent liability. Any increase in the discount rate would reduce the fair value of
the contingent consideration liability whereas any decrease in the discount rate would increase the fair
market value of the contingent consideration liability.

● Similarly,  we  do  not  believe  that  as  of  December  31,  2021  it  is  reasonably  possible  that  a  change  in
development  timelines  and  accordingly  the  timing  of  milestone  payments  would  result  in  a  material
change  of  the  fair  value  of  the  contingent  liability.  An  achievement  of  a  milestone  at  a  later  than
currently expected date would reduce the fair value of the contingent consideration liability whereas an
achievement  at  an  earlier  than  currently  expected  date  would  increase  the  fair  value  of  the  contingent
consideration liability.

● We  initially  recorded  the  contingent  consideration  liability  on  the  Acquisition  Date  assuming  a  40%
probability  of  advancing  the  TLE  research  program  into  clinical  development.  We  developed  this
estimate  using  data  from  an  external  study  regarding  the  average  likelihood  of  advancing  into  clinical
development at a certain stage or preclinical development. Following the designation of a lead candidate
by us in late October 2021 we subsequently increased the probability to 55% and consequently recorded
a $5.8 million loss within research and development expenses in the year ended December 31, 2021, to
increase  the  fair  value  of  the  contingent  consideration  liability  accordingly.  The  fair  value  of  the
contingent consideration liability as of December 31, 2021 amounts to $29.5 million.  If as of December
31, 2021 we had assumed TLE was certain (i.e. 100% probability) to advance into clinical development,
then the fair value of the contingent consideration liability would have increased to $47.0 million. If as
of  December  31,  2021  we  had  assumed  that  we  would  discontinue  development  of  the  TLE  program,
then we could have released the contingent consideration liability to income.

Revenue recognition related to CSL Behring milestones

On June 24, 2020 (the “Signing Date”) we entered into the CSL Behring Agreement. The transaction became

effective on May 6, 2021 (“Closing”).

As of Closing, we identified two material performance obligations related to the CSL Behring Agreement:

(i)

(ii)

Sale of the exclusive global rights to the Product (“License Sale”); and

Generate  information  to  support  the  regulatory  approval  of  the  current  and  next  generation  manufacturing
process  of  Product  and  to  provide  any  such  information  generated  to  CSL  Behring  (“Manufacturing
Development”).

We determined that the fixed upfront payment of $450.0 million and the $12.4 million that we received in relation
to  the  Additional  Covenants  should  be  allocated  to  the  License  Sale.  In  addition,  we  concluded  that  variable  milestone
payments, sales milestone payments and royalties should be allocated to the License Sale performance obligation as well.
We determined that the License Sale was completed on May 6, 2021, when we transferred the license and CSL Behring
assumed full responsibility for the development and commercialization of the Product. Upon the Closing, we evaluated the
amounts of potential payments and the likelihood that the payments will be received. We utilized the most likely amount
method  to  estimate  the  variable  consideration  to  be  included  in  the  transaction  price.  Since  we  cannot  control  the
achievement  of  regulatory  and  first  commercial  sales  milestones,  we  concluded  that  all  potential  payments  were
constrained as of Closing. We determined that we would recognize revenue related to these payments, only to the extent
that  it  becomes  probable  that  no  significant  reversal  of  recognized  cumulative  revenue  will  occur  thereafter.  We  will
include  payments  related  to  sales  milestones  in  the  transaction  price  when  their  achievement  becomes  probable,  and  we
will include royalties on the sale of Product once these have been earned.

We determined that achievement of a total of $55.0 million of milestone payments related to the submissions of a
BLA and MAA is probable as of the time of filing this Annual Report on Form 10-K and hence recorded these as license
revenue in the year ended December 31, 2021. In making this determination we considered that after Closing we believe to
successfully have completed the validation of our manufacturing process for the Product in December 2021 and that CLS
Behring announced the accomplishment of the primary clinical endpoint for the Product in December 2021.

We continue to believe that the achievement of first-sales milestones of $175.0 million are not probable as of the
date of the filing of this Annual Report on Form 10-K as these milestones require regulatory approvals, as well as a sale of
Product by CSL Behring. Additionally, the first sale milestone in a major European country needs to be achieved prior to a
contractually agreed date.

Valuation allowance related to Dutch and U.S. deferred tax assets

We are subject to corporate taxes in the Netherlands. We have been incurring net operating losses in accordance
with the corporate tax laws in almost all years since we founded our business. As of December 31, 2020, the total amount
of net operating losses carried forward under the Dutch tax regime was $588.2 million.

As of December 31, 2020 we reassessed the need for a full valuation allowance in conjunction with entering into
the  CSL  Behring  Agreement.  The  effectiveness  of  the  transactions  contemplated  by  the  CSL  Behring  Agreement  was
contingent  on  completion  of  review  under  antitrust  laws  in  the  United  States,  Australia,  and  the  United  Kingdom.
Regulatory approval in the United States had not occurred at the time of filing our Annual Report on Form 10-K for the
year  ended  December  31,  2020.  At  that  time  we  weighed  all  available  positive  and  negative  evidence,  including  future
income projections from the CSL Behring Agreement, and concluded that it was not more likely than not that the deferred
tax assets will not be realized. Accordingly, we continued to record a full valuation allowance as of December 31, 2020 in
the Netherlands. As of December 31, 2020, our valuation allowance amounted to $150.1 million (2019: $109.9 million). If
we had determined that it had been more likely than not that the deferred tax asset would be realized, then we could have
recorded up to $61.9 million of deferred tax income in the year ended December 31, 2020 from releasing our valuation
allowance and would have recorded deferred tax income for the same amount in the year ended December 31, 2021 from
utilizing the deferred tax asset on closing of the CSL Behring transaction in May 2021.

We are also subject to corporate taxes in the United States. While our operations in the United States had initially
been  incurring  net  operating  tax  losses,  our  subsidiary  in  the  United  States  generated  taxable  income  in  the  fiscal  years
2018, 2019 and 2020. Based on the design of our worldwide operations, we determined as of December 31, 2020 that we
expect to continue to generate taxable income in the United States. during the foreseeable future and therefore determined
that  it  had  become  more  likely  than  not  that  our  United  States  deferred  tax  assets  will  be  realized.  Accordingly,  we
recorded  $16.4  million  of  deferred  tax  income  in  the  year  ended  December  31,  2020  from  releasing  the  full  valuation
allowance against our net deferred tax assets in the United States. We generated taxable income in the United States during
the year ended December 31, 2021 and therefore continue to expect that it is more likely than not that our United States
deferred  tax  assets  will  be  realized.  We  would  be  required  to  record  deferred  tax  expense  to  recognize  a  valuation
allowance on a portion of or possibly even our full U.S. deferred tax asset of $19.9 million as of December 31, 2021 if we
would expect not to meet the above threshold.

Revenue recognition in accordance with the amended BMS CLA

In May 2015, we entered into a collaboration and license agreement and various related agreements with BMS,
which  we  collectively  refer  to  as  the  BMS  CLA,  which  provided  BMS  with  exclusive  access  to  our  gene  therapy
technology  platform  for  the  research,  development  and  commercialization  of  therapeutics  aimed  at  up  to  ten  targets  in
cardiovascular and other diseases.

On December 1, 2020, we and BMS amended the BMS CLA. For a period of one-year from the effective date of
the amended BMS CLA, BMS was able to replace up to two of the four then active Collaboration Targets with two new
targets  in  the  field  of  cardiovascular  disease.  However,  BMS  was  no  longer  entitled  to  add  up  to  six  additional
Collaboration Targets.

86

Table of Contents

During  the  year  ended  December  31,  2020  we  evaluated  the  impact  the  amendment  of  the  BMS  CLA  had  in

relation to our performance obligation related to:

-

providing  access  to  our  technology  and  know-how  in  the  field  of  gene  therapy  as  well  as  actively
contributing to the target selection, the collaboration as a whole, the development during the target selection,
the  pre-clinical  and  clinical  phase  through  participating  in  joint  steering  committee  and  other  governing
bodies (“License Revenue”)

We  did  not  identify  any  new  distinct  performance  obligations  and  determined  the  amended  BMS  CLA  did  not
represent a separate contract in accordance with ASC 606. We evaluated the effect the modification had on our measure of
progress  towards  the  completion  of  our  performance  obligation  in  relation  to  License  Revenue  and  recognized  the
remaining unrecognized License Revenue as of November 30, 2020.

The amount of services we expected to provide was significantly impacted by the number of Collaboration Targets
that  we  estimated  BMS  would  pursue.  Based  on  this  we  concluded  that  our  remaining  performance  obligation  was
immaterial  as  of  December  1,  2020  and  adjusted  our  measure  of  progress  accordingly.  As  such  we  recognized  the
remaining balance of unrecognized License Revenue as of November 30, 2020 of $27.8 million in profit and loss during
the year ended December 31, 2020 as License Revenue from a related party.

Recent Accounting Pronouncement Not Yet Effective

ASU 2021-10: Government Assistance

In  November  2018,  the  FASB  issued  ASU  2021-10,  Government  Assistance  (Topic  832)  which  discusses  the
requirements for disclosures related to transactions with a government. ASU 2021-10 is effective for fiscal years beginning
after December 15, 2021. The new disclosure requirements will require disclosures around 1) information about the nature
of the transactions and the related accounting policy used to account for the transactions, 2) the line items on the balance
sheet and income statement that are affected by the transactions, and the amounts applicable to each financial statement
line item, and 3) significant terms and conditions of the transactions, including commitments and contingencies. An entity
should apply the updates prospectively or retrospectively. We currently include information on government grants and do
not expect this amendment to have a material impact on our consolidated financial statements.

Revenue

BMS

We  recognize  collaboration  revenues  associated  with  Collaboration  Target-specific  pre-clinical  analytical
development  and  process  development  activities  that  are  reimbursable  by  BMS  under  the  BMS  CLA  and  the  amended
BMS CLA as well as other related agreements. Collaboration Revenue related to these contracted services is recognized
when performance obligations are satisfied.

We  recognized  license  revenues  associated  with  the  amortization  of  the  non-refundable  upfront  payment  and
target designation fees we received from BMS in 2015 until December 1, 2020. We evaluated our outstanding performance
obligation  following  the  amendment  of  the  BMS  CLA  on  December  1,  2020  and  determined  that  our  remaining
performance  obligation  is  immaterial.  We  updated  our  measure  of  progress  accordingly  and  amortized  the  remaining
balance of unrecognized revenue as of December 1, 2020. In accordance with the amended BMS CLA, we continue to be
eligible  to  receive  research,  development,  and  regulatory  milestone  payments  as  well  as  sales  milestone  payments  and
royalties for each of the four active Collaboration Targets if defined milestones are achieved in relation to the license to our
technology and know-how. We will recognize revenue from these payments when earned or as sales occur.

CSL Behring

Following the Closing of the CSL Behring agreement, we recognize license revenue related to the License Sale of
the global rights to the Product. We determined that our performance obligation related to the License Sale was satisfied on
Closing  and  recognized  $462.4  million  license  revenue.  We  will  recognize  additional  license  revenue  in  relation  to  the
License  Sale  when  it  becomes  probable  that  regulatory  and  sales  milestone  events  will  be  achieved  as  well  as  when
royalties on sales of Product have been earned. We determined that as of the filing date of this Form 10-K, achievement of
a  total  of  $55.0  million  of  payments  related  to  the  submission  of  a  BLA  and  MAA  for  the  Product  was  probable  and
accordingly recorded license revenue in relation to these milestone payments.

We recognize collaboration revenues associated with Manufacturing Development. We will recognize collaboration

revenue related to a contractual development milestone when it becomes probable the milestone will be achieved.

We recognize collaboration revenues associated with development services that will be reimbursed by CSL Behring
relating to clinical development activities. These services are provided by our employees. Collaboration revenue related to
these contracted services is recognized when the performance obligations are satisfied.

Our revenue for the years ended December 31, 2021, 2020 and 2019 was as follows:

We recognized $517.4 million, $37.3 million, and $5.0 million of license revenue for the years ended December
31, 2021, 2020 and 2019, respectively. The license revenue recognized in 2021 of $517.4 million resulted from the fixed
upfront  payment  of  $450.0  million,  the  $12.4  million  we  received  in  relation  to  the  Additional  Covenants  allocated  to
License sale that we recognized after the Closing of the CSL Behring Agreement on May 6, 2021 as well as a total of $55.0
million  of  payments  related  to  the  CSL  Behring  Agreement  BLA  and  MAA  submission  milestones  that  we  consider
probable as of the filing of these financial statements. We did not recognize any license revenue related to the CSL Behring
Agreement during the years ended December 31, 2020 and 2019.

88

    
    
Table of Contents

The increase in license revenue in 2020 of $32.2 million compared to 2019 primarily resulted from $27.8 million
of  license  revenue  that  we  recognized  as  of  December  1,  2020  from  the  amended  BMS  CLA  as  well  as  $4.4  million
research  milestone  payment  that  we  recorded  in  December  2020  following  the  designation  by  BMS  of  one  of  the  four
Collaboration Targets as a candidate to advance into IND-enabling studies.

We recognized $6.6 million, $0.2 million, and $2.3 million of collaboration revenue for the years ended December
31, 2021, 2020 and 2019, respectively. The increase in collaboration revenue in 2021 of $6.4 million compared to 2020
was  primarily  related  to  the  revenues  related  to  FTE  recharges  of  $2.4  million  recognized  from  the  CSL  Behring
Agreement and $4.2 million recognized from the amended BMS CLA. The decrease in collaboration revenue in 2020 of
$2.1 million compared to 2019 was primarily related to the reduction of activities between the termination of the initial
research term under the BMS CLA in May 2019 and the amendment in December 2020.

Cost of Contract revenues

We  expense  contract  fulfillment  costs  associated  with  license  revenue  recognized  under  the  CSL  Behring
Agreement as costs of contract revenues. These expenses primarily consist of payments we owe to our licensors in relation
to license payments we received from CSL Behring. We incurred $25.0 million of such cost in the year ended December
31, 2021. We did not incur such costs in the years ended December 31, 2020 and 2019.

Research and development expenses

We expense R&D as incurred. Our R&D expenses generally consist of costs incurred for the development of our

target candidates, which include:

● employee-related expenses, including salaries, benefits, travel, and share-based compensation expense;
● costs incurred for laboratory research, preclinical and nonclinical studies, clinical trials, statistical analysis and
report  writing,  and  regulatory  compliance  costs  incurred  with  clinical  research  organizations  and  other  third-
party vendors;

● costs incurred to conduct consistency and comparability studies;
● costs incurred for the development and improvement of our manufacturing processes and methods;
● costs  associated  with  research  activities  for  enabling  technology  platforms,  such  as  next-generation  vectors,

promoters and re-administration of gene therapies;

● costs associated with the rendering of collaboration services as well as the continued development of Product

between the Signing Date and Closing;

● payments related to identifiable intangible assets without an alternative future use;
● facilities,  depreciation,  and  other  expenses,  which  include  direct  and  allocated  expenses  for  rent  and

maintenance of facilities, insurance, and other supplies; and

● changes in the fair value of liabilities recorded in relation to our acquisition of Corlieve.

Our research and development expenses primarily consist of costs incurred for the research and development of our

product candidates, which include:

● Etranacogene dezaparvovec (hemophilia B). We have incurred costs related to the research, development, and
production of etranacogene dezaparvovec for the treatment of hemophilia B. In June 2018, we initiated a pivotal
study. We completed enrollment of the lead-in phase of the pivotal study in September 2019 and dosed a total of
54 patients between January 2019 and March 2020. Following the completion of dosing we initiated activities
related to the preparation of marketing authorization applications in the U.S. and EU, as well as other related
undertakings. During 2020 and up to the Closing of the CSL Behring Agreement we also incurred costs related
to  the  preparation  of  a  BLA  and  MAA  and  for  commercialization  of  the  Product.  We  also  incurred  costs  for
manufacturing  development.  After  the  Closing,  CSL  Behring  is  responsible  for  the  clinical  and  regulatory
development and commercialization of the Product;

● AMT-130 (Huntington’s disease). We have incurred costs related to preclinical and nonclinical studies of AMT-
130 and have been incurring costs related to our Phase I/II trial since February 2019. Since 2021, we have also
incurred costs related to our Phase Ib/II clinical trial in Europe;

● Preclinical  research  programs.  We  incurred  costs  related  to  the  research  of  multiple  preclinical  gene  therapy

product candidates with the potential to treat certain rare and other serious medical conditions; and

89

Table of Contents

● Technology platform development and other related research. We incurred significant research and development

costs related to manufacturing and other enabling technologies that are applicable across all our programs.

Our research and development expenses may vary substantially from period to period based on the timing of our
research  and  development  activities,  including  manufacturing  campaigns,  regulatory  submissions,  and  enrollment  of
patients in clinical trials. The successful development of our product candidates is highly uncertain. Estimating the nature,
timing, or cost of the development of any of our product candidates involves considerable judgment due to numerous risks
and uncertainties associated with developing gene therapies, including the uncertainty of:

● the scope, rate of progress and expense of our research and development activities;
● our ability to successfully manufacture and scale-up production;
● clinical trial protocols, speed of enrollment and resulting data;
● the effectiveness and safety of our product candidates;
● the timing of regulatory approvals; and
● our  ability  to  agree  to  ongoing  development  budgets  with  collaborators  who  share  the  costs  of  our

development programs.

A change in the outcome of any of these variables with respect to our product candidates that we may develop,
including as a result of the COVID-19 pandemic, could mean a significant change in the expenses and timing associated
with the development of such product candidate.

Research  and  development  expenses  for  the  year  ended  December  31,  2021  were  $143.5  million,  compared  to
$122.4  million  and  $94.7  million  for  the  years  ended  December  31,  2020  and  2019,  respectively.  Other  research  and
development  expenses  are  separately  classified  in  the  table  below.  These  are  not  allocated  as  they  are  deployed  across
multiple projects under development.

Direct research and development expenses

Hemophilia B (AMT-060/061)

In  the  years  ended  December  31,  2021,  2020  and  2019,  the  external  costs  for  our  hemophilia  B  program  were
primarily related to the execution of our Phase III clinical trial. During 2020 and up to the Closing of the CSL Behring
Agreement we also incurred costs related to the preparation of a BLA and MAA and for commercialization of the Product.
We also incurred costs for Manufacturing Development. After the Closing, CSL Behring is responsible for the clinical and
regulatory  development  and  commercialization  of  the  Product.  Direct  research  and  development  expenses  related  to
clinical development incurred in the year ended December 31, 2021 are presented net of reimbursements due from CSL
Behring.

In the same period, we also incurred costs related to the long-term follow-up of patients in our Phase I/II clinical
trial of AMT-060 and our Phase IIb clinical trial of etranacogene dezaparvovec. Our Phase IIb dose-confirmation study was
initiated  in  January  2018  and  dosing  occurred  in  July  and  August  2018.  Patients  were  dosed  as  part  of  our  Phase  I/II
clinical trial of AMT-060 in 2015 and 2016.

Huntington disease (AMT-130)

In the years ended December 31, 2021 and 2020, our external costs for the development of Huntington’s disease
were primarily related to the execution of our Phase I/II clinical trial in the United States as well as the preparation of a
Phase  I/IIb  clinical  trial  in  Europe.  In  the  year  ended  December  31,  2019,  our  external  costs  for  the  development  of
Huntington’s disease were primarily related to the preparation of our Phase I/II clinical trial in the United States.

Preclinical programs & platform development

In  the  year  ended  December  31,  2021,  we  incurred  $9.8  million  of  costs  primarily  related  to  our  preclinical
activities  associated  with  product  candidates  for  the  treatment  of  SCA3  (AMT-150),  Fabry  disease  (AMT-191)  and
temporal lobe epilepsy (AMT-260), as well as various other research programs and technology innovation projects.

In  the  year  ended  December  31,  2020,  we  incurred  $6.5  million  of  costs  related  to  related  to  our  preclinical
activities for product candidates including Hemophilia A (AMT-180), SCA3 (AMT-150) and Fabry disease (AMT-190), as
well  as  various  other  research  programs  and  technology  innovation  projects  compared  to  $5.7  million  in  2019.  These
expenses for the year ended December 31, 2020 and 2019 include costs related to our product candidate for Hemophilia A
(AMT-180), which was deprioritized in June 2020.

Other research & development expenses

● We  incurred  $55.7  million  in  employee  and  contractor  expenses  in  the  year  ended  December  31,  2021
compared to $41.7 million in 2020 and $34.0 million in 2019. Our cost increased in 2021 by $14.0 million
compared  to  2020  as  a  result  of  the  recruitment  of  personnel  to  support  the  preclinical  and  clinical
development  of  our  product  candidates.  For  the  same  reason  our  costs  increased  by  $7.7  million  in  2020
compared to 2019;

● We incurred $18.8 million in operating expenses and depreciation expenses related to our rented facilities in
the  year  ended  December  31,  2021  compared  to  $17.4  million  in  2020  and  $15.2  million  in  2019.  The
increase in 2021 compared to 2020 of $1.4 million primarily related to the expansion of Amsterdam facility.
The increase in 2020 compared to 2019 of $2.2 million primarily relates to extending and expanding (as of
June 2019) the lease of our Lexington facility;

● We  incurred  $14.7  million  in  disposables  costs  in  the  year  ended  December  31,  2021  compared  to  $10.2
million in the year ended December 31, 2020 and $8.8 million in the year ended December 31, 2019 related
to miscellaneous other costs we incurred as a result of expanding our organization;

● We  incurred  $12.8  million  in  share-based  compensation  expenses  in  the  year  ended  December  31,  2021
compared to $12.0 million in 2020 and $8.1 million in 2019. The increase in 2021 compared to 2020 of $0.8
million  was  primarily  driven  by  grants  to  newly  recruited  personnel  offset  by  share-based  compensation
expenses  recorded  in  relation  to  the  termination  of  one  of  our  executives  in  2020.  The  increase  in  2020
compared  to  2019  of  $3.9  million  was  driven  primarily  by  grants  to  newly  recruited  personnel  as  well  as
share-based compensation expenses recorded in relation to the termination of one of our executives;

● We incurred $6.7 million of expenses for the year ended December 31, 2021 related to an increase in the fair
value  of  contingent  consideration  associated  with  the  Corlieve  Transaction,  compared  to  nil  for  the  same
periods in 2020 and 2019; and

● We incurred $5.8 million in other expenses in the year ended December 31, 2021 compared to $6.2 million in
2020 and $2.0 million in 2019. The decrease in 2021 compared to 2020 of $0.4 million is a combination of
not incurring any expenses related to license payments without an alternative future use like in 2020 ($3.4
million)  offset  by  various  increases,  including  increases  in  professional  fees  as  a  result  of  expanding  the
organization and to support the cGMP validation of our Lexington facility. The increase in 2020 compared to
2019 of $4.2 million primarily relates to a $3.4 million expense recorded in 2020 related to license payments
that have no alternative future use.

Selling, general and administrative expenses

Our  general  and  administrative  expenses  consist  principally  of  employee,  office,  consulting,  legal  and  other
professional and administrative expenses. We incurred expenses associated with operating as a public company, including
expenses for personnel, legal, accounting and audit fees, board of directors’ costs, directors' and officers' liability insurance
premiums,  Nasdaq  listing  fees,  expenses  related  to  investor  relations  and  fees  related  to  business  development  and
maintaining  our  patent  and  license  portfolio.  Our  selling  costs  include  employee  expenses  as  well  as  professional  fees
related to the preparation of a commercial launch of etranacogene dezaparvovec and advisory fees related to obtaining the
CSL Behring Agreement.

Selling, general and administrative expenses for the year ended December 31, 2021 were $56.3 million, compared

to $42.6 million and $33.5 million for the years ended December 31, 2020 and 2019, respectively.

● We incurred $16.0 million in personnel and contractor expenses in 2021 compared to $13.6 million in 2020
and $10.5 million in 2019. The increase of $2.4 million in 2021 compared to 2020 was primarily related to
the recruitment of personnel; and the increase of $3.1 million in 2020 compared to 2019 was primarily driven
by an increase in personnel and contractor related expenses to support our growth;

● We incurred $12.8 million of share-based compensation expenses in 2021 compared to $9.8 million in 2020
and $9.4 million in 2019. The increase in 2021 compared to 2020 of $3.0 million was primarily related to the
increase in awards granted, including those to newly recruited personnel and the increase in 2020 compared
to 2019 of $0.4 million was also primarily driven by the increase in awards granted including those to newly
recruited personnel;

● We incurred $9.4 million in professional fees in 2021 compared to $8.0 million in 2020 and $6.0 million in
2019.  We  regularly  incur  accounting,  audit  and  legal  fees  associated  with  operating  as  a  public  company.
Additionally, in the years ended December 31, 2021 and December 31, 2020, we incurred professional fees
in relation to our licensing transaction with CSL Behring and our acquisition of Corlieve; and

● We incurred $5.1 million in financial advisory fees in relation to our licensing transaction with CSL Behring

in the year ended December 31, 2021, compared to nil in the same period in 2020 and 2019.

Other items, net

We recognized $3.0 million in other income in relation to the equity stake received in VectorY B.V. in conjunction
with a settlement agreement that the Company and VectorY B.V. entered into in April 2021 in the year ended December 31,
2021, compared to no such income for the same periods in 2020 and 2019.

We recognized $2.6 million in other income of employee retention credit under the U.S. CARES Act in the year

ended December 31, 2021, compared to no such income for the same periods in 2020 and 2019.

In  2021,  we  recognized  $5.3  million  in  income  related  to  payments  received  from  European  authorities  to
subsidize our research and development efforts in the Netherlands compared to $1.9 million in 2020 and $0.7 million in
2019.

Other income for the years ended December 31, 2021, 2020 and 2019 also includes income from the subleasing of

a portion of our Amsterdam facility. We present expenses related to such income as other expense.

Other non-operating items, net

We recognize interest income associated with our cash and cash equivalents.

We hold monetary items and enter into transactions in foreign currencies, predominantly in euros and U.S. dollars.

We recognize foreign exchange results related to changes in these foreign currencies.

We  issued  warrants  to  Hercules  in  2013  and  to  BMS  in  2015.  We  recognize  changes  in  the  fair  value  of  these
warrants within other non-operating (losses) / gains. Following the termination of the BMS warrants on December 1, 2020,
we no longer recognize changes in the fair value of these warrants within other non-operating (losses) / gains. As of the
same  date,  we  recognized  a  derivative  financial  liability  related  to  the  CoC-payment.  Following  the  exercise  of  the
warrants  by  Hercules  in  February  2019  we  no  longer  recognize  changes  in  the  fair  value  of  these  warrants  within  other
non-operating (losses) / gains.

Our non-operating items, net, for the years ended December 31, 2020, 2019 and 2018 were as follows:

We recognized $0.2 million interest income in 2021, $0.9 million in 2020 and $3.5 million in 2019. Our interest
income decreased in 2021 by $0.7 million compared to 2020 and in 2020 decreased by $2.6 million compared to 2019 due
to a reduction in market interest rates during 2020.

We recognized $7.5 million interest expense in 2021, $3.8 million in 2020 and $3.8 million in 2019. Our interest
expense in 2021 primarily increased by $3.6 million compared to 2020 due to the additional $35.0 million we drew down
on our loan facility from Hercules in January of 2021. Our interest expense in 2020 was unchanged compared to 2019 as
our outstanding debt remained unchanged.

Table of Contents

In 2021, we recognized a net foreign currency gain of $29.7 million related to our borrowings from Hercules and
our  cash  and  cash  equivalents  as  well  as  loans  between  entities  within  the  uniQure  group,  compared  to  a  net  loss  of
$13.6 million in 2020 and a net loss of $0.3 million in 2019.

In 2021, we recognized a $0.2 million net loss within Other non-operating (losses) / gains related to an increase in
the  fair  value  market  value  of  derivative  financial  liability  related  to  the  CoC-payment,  compared  to  a  net  gain  of
$0.5 million in 2020 and a net loss of $2.5 million in 2019. The increase in the fair market value of the derivative financial
liability  in  2021  primarily  related  to  unwinding  the  discounting  of  the  potential  CoC-payment.  The  changes  in  2020
compared to 2019 result from a $3.1 million gain that we recognized related to fair value changes of the BMS warrants
(compared to $2.5 million loss in 2019), which includes an $0.8 million gain that we recognized related to the termination
of the BMS warrants in December 2020, and a loss of $2.6 million to recognize the derivative financial liability for the
CoC-payment on December 1, 2020.

Income tax

We recognized $3.2 million of deferred tax expenses in 2021, compared to $16.4 million of deferred tax income in
2020 and $0.0 million in 2019. Deferred tax expense recorded in 2021 results from the consumption of net operating tax
losses  by  our  U.S.  entity  as  well  as  deferred  tax  expense  resulting  from  the  release  of  valuation  allowance  for  the  tax
benefit of share issuance costs within the Netherlands. Deferred tax income recorded in 2020 results from the release of the
valuation  allowance  recorded  for  our  net  deferred  tax  assets  by  our  U.S.  entity.  We  did  not  record  changes  in  valuation
allowances in 2019.

Financial Position, Liquidity and Capital Resources

As  of  December  31,  2021,  we  had  cash,  cash  equivalents  and  restricted  cash  of  $559.4  million,  which  include
payments received from CSL Behring following the Closing. Until such time, if ever, as we can generate substantial cash
flows from successfully commercializing our proprietary product candidates, we expect to finance our cash needs through
a  combination  of  equity  offerings,  debt  financings,  collaborations,  strategic  alliances  and  marketing,  distribution,  and
licensing arrangements. We believe that our cash and cash equivalents will fund our operations into the first half of 2025
assuming  achievement  of  $230.0  million  related  to  BLA  and  MAA  submissions  as  well  as  first  commercial  sales
milestones under the CSL Behring Agreement. Our material cash requirements include the following contractual and other
obligations:

Debt

As  of  December  31,  2021,  we  had  an  outstanding  loan  amount  owed  to  Hercules  for  an  aggregate  principal
amount  of  $100.0  million,  with  $8.0  million  payable  within  12  months.  Future  interest  payments  and  financing  fees
associated with the loan total $35.6 million, with $8.0 million payable within 12 months. We are contractually required to
repay the $100.0 million in equal installments between December 2024 and December 2025 or in full in December 2025 if,
prior to June 30, 2024, either (a) the BLA for AMT-061 is approved by the FDA or (b) AMT-130 is advanced into a pivotal
trial.

Leases

We  entered  into  lease  arrangements  for  facilities,  including  corporate,  manufacturing  and  office  space.  As  of
December 31, 2021, we had fixed lease payment obligations of $65.2 million, with $6.7 million payable within 12 months.
The  fixed  lease  payment  obligations  include  payments  owed  under  signed  lease  arrangements  that  are  expected  to
commence in 2022.

Commitments related to Corlieve acquisition (nominal amounts)

In  relation  to  the  Corlieve  Transaction,  we  entered  into  commitments  to  make  payments  to  the  former
shareholders upon the achievement of certain contractual milestones. The commitments include payments related to post-
acquisition services that we agreed to as part of the SPA. As of December 31, 2021, our commitment amount is $229.1
million.  The  timing  of  achieving  these  milestones  and  consequently  the  timing  of  payments,  as  well  as  whether  the
milestone  will  be  achieved  at  all,  is  generally  uncertain  with  the  exception  of  a  payment  we  made  in  February  2022  to
acquire the remaining outstanding shares as well as certain payments for post-acquisition services in 2022. These payments
are owed in Euro and have been translated at the foreign exchange rate as of December 31, 2021, of $1.13/€1.00. As of
December 31, 2021, we expect these obligations will become payable between 2022 and 2031. If and when due, up to 25%
of the milestone payments can be settled with our ordinary shares.

Commitments related to licensors and financial advisors

We have obligations to make future payments to third parties that become due and payable on the achievement of
certain development, regulatory and commercial milestones (such as the start of a clinical trial, filing of a BLA, approval
by the FDA or product launch) or as a result of collecting payments related to our License Sale to CSL Behring. We also
owe payments to a financial advisor related to any payments we will collect under the CSL Behring Agreement.

We  had  previously  incurred  losses  and  cumulative  negative  cash  flows  from  operations  since  our  business  was
founded by our predecessor entity AMT Holding N.V. in 1998. As a result of receiving the upfront payment upon Closing
of the CSL Behring Agreement, we generated $288.0 million cash flows from operating activities during the year ended
December  31,  2021.  We  recorded  net  income  of  $329.6  for  the  year  ended  December  31,  2021,  and  a  net  loss  of
$125.0 million in 2020, and a net loss of $124.2 million in 2019. As of December 31, 2021, we had an accumulated deficit
of $455.1 million.

Sources of liquidity

From  our  first  institutional  venture  capital  financing  in  2006  through  May  2021,  we  funded  our  operations
primarily  through  private  and  public  placements  of  equity  securities  and  convertible  and  other  debt  securities  as  well  as
payments  from  our  collaboration  partners.  In  May  2021,  we  received  a  $462.4  million  cash  payment  due  from  CSL
Behring  upon  Closing.  We  expect  to  collect  $55.0  million  from  CSL  Behring  following  the  submissions  of  a  BLA  and
MAA for AMT-061. In addition, we could potentially receive regulatory, first commercial sales and development milestone
payments as well as royalties and sales milestone payments from CSL Behring.

On  March  1,  2021,  we  entered  into  a  Sales  Agreement  with  SVB  Leerink  with  respect  to  an  ATM  offering
program,  under  which  we  may,  from  time  to  time  in  our  sole  discretion,  offer  and  sell  through  SVB  Leerink,  acting  as
agent, our ordinary shares, up to an aggregate offering price of $200.0 million. We will pay SVB Leerink a commission
equal to 3% of the gross proceeds of the sales price of all ordinary shares sold through it as a sales agent under the Sales
Agreement. In the year ended December 30, 2021, we received net proceeds of $29.6 million from the issuance of 921,730
ordinary shares that took place during March and April of this year.

On  September  10,  2019,  we  completed  a  follow-on  public  offering  of  4,891,305  ordinary  shares  at  a  public
offering price of $46.00 per ordinary share, and on September 13, 2019, we completed the sale of an additional 733,695
ordinary shares at a public offering price of $46.00 per ordinary share pursuant to the exercise by the underwriters of the
option to purchase additional ordinary shares, resulting in total gross proceeds to us of $258.8 million. The net proceeds
from  this  offering  were  $242.7  million,  after  deducting  underwriting  discounts  and  commissions  and  other  offering
expenses  payable  by  us.  We  deducted  $0.6  million  of  expenses  incurred  related  to  this  offering  from  additional  paid-in
capital  in  the  accompanying  consolidated  balance  sheets  and  reflected  this  within  the  proceeds  from  public  offering  of
shares, net of issuance costs within the cash flows from financing activities.

On January 29, 2021, we drew down $35 million under our 2021 Amended Facility with Hercules. We drew down

a further $30 million under our 2021 Restated Facility with Hercules.

We are subject to certain covenants under our 2021 Restated Facility and may become subject to covenants under
any  future  indebtedness  that  could  limit  our  ability  to  take  specific  actions,  such  as  incurring  additional  debt,  making
capital expenditures, or declaring dividends, which could adversely impact our ability to conduct our business. In addition,
our pledge of assets as collateral to secure our obligations under the 2021 Restated Facility may limit our ability to obtain
debt financing. The 2021 Restated Facility permits us to issue up to $500.0 million of convertible debt as well as to enter
into a transaction to sell the royalties under the CSL Behring agreement subject to certain conditions.

To the extent we need to finance our cash needs through equity offerings or debt financings, such financing may
be subject to unfavorable terms including without limitation, the negotiation and execution of definitive documentation, as
well as credit and debt market conditions, and we may not be able to obtain such financing on terms acceptable to us or at
all.  If  financing  is  not  available  when  needed,  including  through  debt  or  equity  financings,  or  is  available  only  on
unfavorable terms, we may be unable to meet our cash needs. If we raise additional funds through collaborations, strategic
alliances or marketing, distribution, or licensing arrangements with third parties, we may have to relinquish valuable rights
to our technologies, future revenue streams or product candidates or grant licenses on terms that may not be favorable to
us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay,
limit,  reduce  or  terminate  our  product  development  or  future  commercialization  efforts  or  grant  rights  to  develop  and
market product candidates that we would otherwise prefer to develop and market ourselves, which could have a material
adverse effect on our business, financial conditions, results of operations and cash flows.

Net  cash  generated  from  operating  activities  was  $288.0  million  for  the  year  ended  December  31,  2021,  and
consisted of net income of $329.6 million adjusted for non-cash items, including depreciation and amortization expense of
$7.3 million, share-based compensation expense of $25.6 million, a change in fair value of contingent consideration of $6.8
million, unrealized foreign exchange gains of $31.3 million, a change in deferred taxes of $3.2 million and other non-cash

assets and liabilities of $50.3 million, which includes $55.0 million recognized as a contract asset related to probable CSL
Behring  milestone  payments.  Additionally,  these  changes  also  related  to  a  net  increase  in  accounts  receivable,  prepaid
expenses,  and  other  current  assets  and  receivables  of  $4.0  million  primarily  related  to  an  increase  in  various  prepaids,
including  those  related  to  clinical  trials,  partially  offset  by  decrease  in  receivables  as  a  result  of  collection  of  the  BMS
milestone  that  was  recorded  as  of  December  31,  2020  and  collection  of  the  CSL  Behring  receivables  recorded  as  of
December  31,  2020  for  expenses  for  which  we  had  a  right  of  reimbursement  and  a  net  increase  in  accounts  payable,
accrued expenses, other liabilities, and operating leases of $8.5 million primarily related to an increase in various accruals
for  goods  received  from  and  services  provided  by  vendors  and  an  increase  in  personnel  accruals. Net income primarily
consisted  of  $462.4  million  license  revenue  recognized  on  Closing  and  $55.0  million  license  revenue  related  to  the
submissions of a BLA and MAA that is considered probable as of the time of filing these financial statements.

Net  cash  used  in  operating  activities  was  $134.8  million  for  the  annual  period  ended  December  31,  2020,  and
consisted of a net loss of $125.0 million adjusted for non-cash items, including depreciation and amortization expense of
$10.6 million, share-based compensation expense of $21.8 million, fair value gain of derivative financial instruments of
$0.5 million, unrealized foreign exchange loss of $14.7 million, a change in deferred tax income of $16.4 million and a
decrease in unamortized deferred revenue of $33.6 million. Net cash used in operating activities also included unfavorable
changes  in  operating  assets  and  liabilities  of  $6.5  million.  These  changes  primarily  related  to  a  net  increase  in  accounts
receivable and accrued income, prepaid expenses, and other current assets of $7.0 million and a net increase in accounts
payable, accrued expenses, other liabilities, and operating leases of $0.5 million.

Net  cash  used  in  operating  activities  was  $98.7  million  for  the  annual  period  ended  December  31,  2019,  and
consisted of a net loss of $124.2 million adjusted for non-cash items, including depreciation and amortization expense of
$6.7 million, share-based compensation expense of $17.5 million, fair value loss of derivative financial instruments of $2.5
million, unrealized foreign exchange loss of $0.9 million, and a decrease in unamortized deferred revenue of $5.0 million.
Net cash used in operating activities also included changes in operating assets and liabilities of $2.9 million. These changes
primarily related to a net increase in accounts receivable and accrued income, prepaid expenses, and other current assets of
$4.8 million and a net increase in accounts payable, accrued expenses, other liabilities, and operating leases of $7.7 million
primarily related to our clinical trials and facilities.

expansion of our research and development activities as well as the construction of a cleanroom designed to be capable of
manufacturing cGMP materials at a 500-liter scale.

In 2021, we invested $5.0 million in our facility in Lexington compared to $2.7 million in 2020 and $4.2 million
in 2019. Our investments in 2019 primarily relate to improvements we made to the additional space rented from June 1,
2019.

In January 2021, we received $34.6 million net proceeds from the 2021 Amended Facility and in December 2021

we received $29.5 million net proceeds from the 2021 Restated Facility for combined net proceeds of $64.1 million.

We received net proceeds of $29.6 million associated with our ATM offering in March and April 2021 and $242.7

million associated with our public follow-on offering in September 2019.

In 2021, we received $2.8 million from the exercise of options to purchase ordinary shares issued in accordance

with our share incentive plans, compared to $7.4 million in 2020 and $5.6 million in 2019.

Upon the acquisition of Corlieve, Corlieve held loans with an outstanding amount equal to EUR 1.4 million ($1.6

million). During the year ended December 31, 2021, the loans were repaid in their entirety.

We  received  net  proceeds  of  $0.5  million  associated  with  the  exercise  of  the  Hercules  warrants  by  Hercules  in

February 2019.

Funding requirements

We believe our cash and cash equivalents as of December 31, 2021 will fund our operations into the first half of
2025  assuming  achievement  of  $230.0  million  related  to  BLA  and  MAA  submissions  as  well  as  first  commercial  sales
milestones under the CSL Behring Agreement. Our future capital requirements will depend on many factors, including but
not limited to:

● achieving the milestones and royalties as defined within the CSL Behring Agreement;
● the payment of milestone payments that we might owe to former shareholders of Corlieve;
● the scope, timing, results, and costs of our current and planned clinical trials, including those for AMT-130 in

Huntington’s disease;

● the extent to which we acquire or in-license other businesses, products, product candidates or technologies;
● the amount and timing of revenue, if any, we receive from commercial sales of any product candidates for which

we, or our collaboration partner, receives marketing approval in the future;

● the amount and timing of revenue, if any, we receive from manufacturing products for CSL Behring;
● the scope, timing, results and costs of preclinical development and laboratory testing of our additional product

candidates;

● the need for additional resources and related recruitment costs to support the preclinical and clinical development

of our product candidates;

● the  need  for  any  additional  tests,  studies,  or  trials  beyond  those  originally  anticipated  to  confirm  the  safety  or

efficacy of our product candidates and technologies;

● the cost, timing and outcome of regulatory reviews associated with our product candidates;
● our ability to enter into collaboration arrangements in the future;
● the costs and timing of preparing, filing, expanding, acquiring, licensing, maintaining, enforcing, and prosecuting

patents and patent applications, as well as defending any intellectual property-related claims;

● the repayments of the principal amount of our venture debt loan with Hercules, which following the December
15, 2021 amendment will be due in equal installments between December 2024 and December 2025 or in full in
December 2025 if, prior to June 30, 2024, either (a) the BLA for AMT-061 is approved by the FDA or (b) AMT-
130 is advanced into a pivotal trial;

● the costs associated with maintaining quality compliance and optimizing our manufacturing processes, including

the operating costs associated with our Lexington, Massachusetts manufacturing facility; and
● the costs associated with increasing the scale and capacity of our manufacturing capabilities.

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk

We  are  exposed  to  a  variety  of  financial  risks  in  the  normal  course  of  our  business,  including  market  risk
(including  currency,  price,  and  interest  rate  risk),  credit  risk  and  liquidity  risk.  Our  overall  risk  management  program
focuses  on  preservation  of  capital  and  the  unpredictability  of  financial  markets  and  has  sought  to  minimize  potential
adverse effects on our financial performance and position.

Market Risk

Currency risk

We are exposed to foreign exchange risk arising from various currencies, primarily with respect to the U.S. dollar
and euro and to a lesser extent to the British pound and the Swiss Franc. As our U.S. operating entity primarily conducts its
operations in U.S. dollars, its exposure to changes in foreign currency is insignificant. Similarly the exposure to changes in
foreign currencies of our Swiss and French entities are insignificant as well.

Our Dutch entities hold significant amounts of U.S. dollars in cash and cash equivalents, have debt and interest
obligations to Hercules denominated in U.S. dollars, generate collaboration revenue denominated in U.S. dollars, receive
services  from  vendors  denominated  in  U.S.  dollars  and  occasionally  British  Pounds  and  fund  the  operations  of  our  U.S.
operating entity in U.S. dollars. Foreign currency denominated account receivables and account payables are short-term in
nature (generally 30 to 45 days).

99

Table of Contents

Variations  in  exchange  rates  will  impact  earnings  and  other  comprehensive  income  or  loss.  On  December  31,
2021, if the euro had weakened 10% against the U.S. dollar with all other variables held constant, pre-tax earnings for the
year would have been $42.2 million higher (December 31, 2020: $13.0 million higher), and other comprehensive income
or  loss  would  have  been  $23.5  million  higher  (December  31,  2020:  $5.2  million  higher).  Conversely,  if  the  euro  had
strengthened 10% against the U.S. dollar with all other variables held constant, pre-tax earnings for the year would have
been $42.2 million lower (December 31, 2020: $13.0 million lower), and other comprehensive income or loss would have
been $31.6 million lower (December 31, 2020: $8.3 million lower).

We  strive  to  mitigate  foreign  exchange  risk  through  holding  sufficient  funds  in  euro  and  dollars  to  finance

budgeted cash flows for the next year.

The sensitivity in other comprehensive income to fluctuations in exchange rates primarily relates to the translation

of the net assets of our Dutch entities from their functional currency euro into our reporting currency U.S. dollar.

Price risk

The  market  prices  for  the  provision  of  preclinical  and  clinical  materials  and  services,  as  well  as  external

contracted research, may vary over time.

The commercial prices of any of our products or product candidates are currently uncertain.

We are not exposed to commodity price risk.

We do not hold investments classified as available-for-sale or at fair value through profit or loss; therefore, we are

not exposed to equity securities price risk.

Interest rate risk

Our  interest  rate  risk  arises  from  short-  and  long-term  debt.  In  June  2013,  we  entered  into  the  Hercules
Agreement,  which  was  last  amended  and  restated  in  December  2021,  under  which  our  borrowings  bear  interest  at  a
variable  rate  with  a  fixed  floor.  Long-term  debt  issued  at  fixed  rates  expose  us  to  fair  value  interest  rate  risk.  As  of
December 31, 2021, the loan bore an interest rate of 7.95%.

As  of  December  31,  2021,  if  interest  rates  on  borrowings  had  been  1.0%  higher  with  all  other  variables  held

constant, pre-tax earnings for the year would have been $0.7 million (2020: $0.3 million; 2019: $0.3 million) lower.

Credit Risk

Credit risk is managed on a consolidated basis. Credit risk arises from cash and cash equivalents and deposits with
banks  and  financial  institutions,  outstanding  receivables  and  committed  transactions  with  collaboration  partners  and
security deposits paid to landlords. We currently have no wholesale debtors other than BMS and CSL Behring.

We deposited funds as security to our landlords related to our facility in Lexington, Massachusetts, and our facility
in  Amsterdam.  We  also  deposited  funds  to  the  provider  of  our  U.S.  corporate  credit  cards.  The  deposits  are  neither
impaired nor past due.

100

Table of Contents

Our  cash  and  cash  equivalents  include  bank  balances,  demand  deposits  and  other  short-term  highly  liquid
investments (with maturities of less than three months at the time of purchase) that are readily convertible into a known
amount of cash and are subject to an insignificant risk of fluctuation in value. Restricted cash includes deposits made in
relation to facility leases. Cash, cash equivalents and restricted cash were placed at the following banks:

We previously had BMS warrants under the BMS CLA which we derecognized on December 1, 2020 when these
were terminated by the amended BMS CLA. On December 1, 2020 we recognized a derivative financial liability related to
the  CoC-payment.  Generally,  the  CoC-payment  would  be  due  to  BMS  upon  the  consummation  of  a  change  in  control
transaction prior to November 30, 2026 or BMS’s delivery of cessation notices for all four active Collaboration Targets.
The derivative financial liability therefore has no contractual maturity date.

In  relation  to  the  Corlieve  Transaction,  we  entered  into  commitments  to  make  payments  to  the  former
shareholders upon the achievement of certain contractual milestones. The commitments include payments related to post-
acquisition services that we agreed to as part of the SPA. The timing of achieving these milestones, as well as whether the
milestone will be achieved at all, and consequently the timing of payments is generally uncertain with the exception of a
payment we owe upon acquiring the remaining outstanding shares as well as certain payments for post-acquisition services
in  2022.  We  expect  these  obligations  will  become  payable  between  2022  and  2031.  If  and  when  due,  up  to  25%  of  the
milestone payments can be settled with our ordinary shares.

Evaluation of Disclosure Controls and Procedures

Our  management,  with  the  participation  of  our  chief  executive  officer  (“CEO”,  our  principal  executive  officer)
and chief financial officer (“CFO”, our principal financial officer), evaluated the effectiveness of our disclosure controls
and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the
“Exchange  Act”))  as  of  December  31,  2021.  Based  on  such  evaluation,  our  CEO  and  CFO  have  concluded  that  as  of
December 31, 2021, our disclosure controls and procedures were effective.

Management’s Annual Report on Internal Control Over Financial Reporting

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

We  assessed  the  effectiveness  of  our  internal  control  over  financial  reporting  as  of  December  31,  2021.  This
assessment was performed under the direction and supervision of our CEO and CFO and based on criteria established in
Internal  Control  -  Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway
Commission (“COSO”). Our management’s assessment of the effectiveness of our internal control over financial reporting
included  testing  and  evaluating  the  design  and  operating  effectiveness  of  our  internal  controls.  In  our  management’s
opinion, we have maintained effective internal control over financial reporting as of December 31, 2021, based on criteria
established in the COSO 2013 framework.

Table of Contents

Our  independent  registered  public  accounting  firm,  which  has  audited  the  consolidated  financial  statements
included in this Annual Report on Form 10-K, has also issued an audit report on the effectiveness of our internal control
over financial reporting as of December 31, 2021. Their report is filed within this Annual Report on Form 10-K.

Inherent Limitations of Internal Controls

Our management, including our CEO and CFO, does not expect that our disclosure controls and procedures or our
internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can
provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent
limitations  in  all  control  systems,  no  evaluation  of  controls  can  provide  absolute  assurance  that  all  control  issues  and
instances  of  fraud,  if  any,  within  the  Company  have  been  detected.  These  inherent  limitations  include  the  realities  that
judgments  in  decision-making  can  be  faulty,  and  that  breakdowns  can  occur  because  of  a  simple  error  or  mistake.
Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or
by management override of the control. The design of any system of controls also is based in part upon certain assumptions
about  the  likelihood  of  future  events,  and  there  can  be  no  assurance  that  any  design  will  succeed  in  achieving  its  stated
goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions,
or the degree of compliance with the policies or procedures may deteriorate. 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. Because of its inherent limitations, internal control
over financial reporting may not prevent or detect misstatements due to error or fraud.

Changes in internal control over financial reporting

During the fourth quarter of 2021, there were no changes in our internal control over financial reporting (as defined
in  Rule  13a-15(f)  under  the  Exchange  Act)  that  materially  affected,  or  are  reasonably  likely  to  materially  affect,  our
internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors
uniQure N.V.:

Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting

We have audited the accompanying consolidated balance sheets of uniQure N.V. and subsidiaries (‘the Company’)
as of December 31, 2021 and 2020, the related consolidated statement of operations and comprehensive loss, shareholders’
equity, and cash flows for each of the years in the three-year period ended December 31, 2021, and the related notes
(collectively, the consolidated financial statements). We also have audited the Company’s internal control over financial
reporting as of December 31, 2021, 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 consolidated financial statements referred to above present fairly, in all material respects, the
financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows
for  each  of  the  years  in  the  three  year-period  ended  December  31,  2021,  in  conformity  with  U.S.  generally  accepted
accounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal control over
financial  reporting  as  of  December  31,  2021  based  on  criteria  established  in  Internal  Control  –  Integrated  Framework
(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, 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  consolidated  financial  statements  and  an  opinion  on  the
Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with
the  Public  Company  Accounting  Oversight  Board  (United  States)  (PCAOB)  and  are  required  to  be  independent  with
respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the
Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan
and  perform  the  audits  to  obtain  reasonable  assurance  about  whether  the  consolidated  financial  statements  are  free  of
material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was
maintained in all material respects.

Our audits of the consolidated financial statements 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. 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  audits  also  included  performing  such  other
procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our
opinions.

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.

Critical Audit Matter

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

Evaluation of the acquisition of Corlieve as a business combination

As discussed in Notes 2.3.5 and 3 to the consolidated financial statements, the Company acquired 97.7% of the

outstanding ordinary shares of Corlieve for a total purchase price of EUR 65.8 million. The Company applied the
applicable accounting guidance which requires the acquirer to assess whether the acquisition should be accounted for as an
asset acquisition or a business combination.

We identified the evaluation of the acquisition as a business combination to be a critical audit matter. This

evaluation required significant auditor judgement to assess whether or not substantially all of the fair value of the gross
assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets based on the similarities
of risks associated with managing and creating outputs from the assets, including the acquired workforce and identification
of intangible assets.

The following are the primary procedures we performed to address this critical audit matter:

‒ We evaluated the design and tested the operating effectiveness of certain internal controls related to the business
combination process, including controls related to technical accounting review and over the completeness of
assets and liabilities acquired.

‒ We read the sale and purchase agreement and performed inquires with management and business development

personnel to understand the business rationale for acquiring Corlieve.

‒ We read the employment terms and inquired of management and business development personnel to  challenge

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.

General business information

uniQure  (the  “Company”)  was  incorporated  on  January  9,  2012  as  a  private  company  with  limited  liability
(besloten vennootschap met beperkte aansprakelijkheid) under the laws of the Netherlands. The Company is a leader in the
field of gene therapy and seeks to deliver to patients suffering from rare and other devastating diseases single treatments
with  potentially  curative  results.  The  Company’s  business  was  founded  in  1998  and  was  initially  operated  through  its
predecessor company, Amsterdam Molecular Therapeutics Holding N.V (“AMT”). In 2012, AMT undertook a corporate
reorganization, pursuant to which uniQure B.V. acquired the entire business and assets of AMT and completed a share-for-
share exchange with the shareholders of AMT. Effective February 10, 2014, in connection with its initial public offering,
the Company converted into a public company with limited liability (naamloze vennootschap) and changed its legal name
from uniQure B.V. to uniQure N.V.

The Company is registered in the trade register of the Dutch Chamber of Commerce (Kamer van Koophandel) in
Amsterdam, the Netherlands under number 54385229. The Company’s headquarters are in Amsterdam, the Netherlands,
and its registered office is located at Paasheuvelweg 25, Amsterdam 1105 BP, the Netherlands and its telephone number is
+31 20 240 6000. The Company’s website address is www.uniqure.com.

The  Company’s  ordinary  shares  are  listed  on  the  Nasdaq  Global  Select  Market  and  trade  under  the  symbol

“QURE”.

2.

Summary of significant accounting policies

2.1         Basis of preparation

The  Company  prepared  its  consolidated  financial  statements  in  compliance  with  generally  accepted  accounting
principles  in  the  United  States  (“U.S.  GAAP”).  Any  reference  in  these  notes  to  applicable  guidance  is  meant  to  refer  to
authoritative U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update
(“ASU”) of the Financial Accounting Standards Board (“FASB”).

The  consolidated  financial  statements  have  been  prepared  under  the  historical  cost  convention,  except  for

derivative financial instruments and contingent consideration, which are recorded at fair value through profit or loss.

The  consolidated  financial  statements  are  presented  in  U.S.  dollars,  except  where  otherwise  indicated.
Transactions  denominated  in  currencies  other  than  U.S.  dollars  are  presented  in  the  transaction  currency  with  the  U.S.
dollar amount included in parenthesis, converted at the foreign exchange rate as of the transaction date.

The  consolidated  financial  statements  presented  have  been  prepared  on  a  going  concern  basis  based  on  the
Company’s  cash  and  cash  equivalents  as  of  December  31,  2021  and  the  Company’s  budgeted  cash  flows  for  the  twelve
months following the issuance date.

114

Table of Contents

2.2         Use of estimates

The preparation of consolidated financial statements, in conformity with U.S. GAAP and Securities and Exchange
Commission  (“SEC”)  rules  and  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 treatment of the share and purchase agreement (“SPA”) entered into on
June 21, 2021 to acquire all of the outstanding ordinary shares of Corlieve Therapeutics SAS (“Corlieve”), a privately held
French  gene  therapy  company  (“Corlieve  Transaction”),  the  treatment  of  the  commercialization  and  license  agreement
entered into (“CSL Behring Agreement”) between the Company and CSL Behring LLC (“CSL Behring”), the assessment
of a valuation allowance on the Company’s deferred tax assets in the Netherlands and the U.S., and the December 1, 2020,
amendment  (“amended  BMS  CLA”)  of  the  2015  collaboration  and  license  agreement  (“BMS  CLA”)  between  the
Company and Bristol-Myers Squibb (“BMS”). 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.

2.3         Accounting policies

The principal accounting policies applied in the preparation of these consolidated financial statements are set out

below. These policies have been consistently applied to all the years presented, unless otherwise stated.

2.3.1      Consolidation

The  consolidated  financial  statements  comprise  the  financial  statements  of  the  Company  and  its  subsidiaries.
Subsidiaries are all entities over which the Company has a controlling financial interest either through variable interest or
through voting interest. Currently, the Company has no involvement with variable interest entities.

Inter-company  transactions,  balances,  income,  and  expenses  on  transactions  between  uniQure  entities  are
eliminated in consolidation. Profits and losses resulting from inter-company transactions that are recognized in assets are
also  eliminated.  Accounting  policies  of  subsidiaries  have  been  changed  where  necessary  to  ensure  consistency  with  the
policies adopted by the Company.

2.3.2      Current versus non-current classification

The Company presents assets and liabilities in the consolidated balance sheets based on current and non-current

classification.

The term current assets is used to designate cash and other assets, or resources commonly identified as those that
are reasonably expected to be realized in cash or sold or consumed during the normal operating cycle of the business. The
Company’s normal operating cycle is twelve months. All other assets are classified as non-current.

The term current liabilities is used principally to designate obligations whose liquidation is reasonably expected to
require  the  use  of  existing  resources  properly  classifiable  as  current  assets,  or  the  creation  of  other  current  liabilities.
Current liabilities are expected to be settled in the normal operating cycle. The Company classifies all other liabilities as
non-current.

Deferred tax assets and liabilities are classified as non-current assets and liabilities, if any.

2.3.3      Foreign currency translation

The functional currency of the Company and each of its entities (except for uniQure Inc. and Corlieve AG) is the
euro (€). This represents the currency of the primary economic environment in which the entities operate. The functional
currency  of  uniQure  Inc.  is  the  U.S.  dollar  ($)  and  the  functional  currency  of  Corlieve  AG  is  the  Swiss  Franc.  The
consolidated financial statements are presented in U.S. dollars.

115

Table of Contents

Foreign  currency  transactions  are  measured  and  recorded  in  the  functional  currency  using  the  exchange  rates
prevailing  at  the  dates  of  the  transactions.  Foreign  exchange  gains  and  losses  resulting  from  the  settlement  of  such
transactions and from the re-measurement of monetary assets and liabilities denominated in foreign currencies at exchange
rates prevailing at balance sheet date are recognized in profit and loss.

Upon consolidation, the assets and liabilities of foreign operations are translated into the functional currency of
the  shareholding  entity  at  the  exchange  rates  prevailing  at  the  balance  sheet  date;  items  of  income  and  expense  are
translated  at  monthly  average  exchange  rates.  The  consolidated  assets  and  liabilities  are  translated  from  uniQure  N.V.’s
functional currency, euro, into the reporting currency U.S. dollar at the exchange rates prevailing at the balance sheet date;
items of income and expense are translated at monthly average exchange rates. Issued capital and additional paid-in capital
are translated at historical rates with differences to the balance sheet date rate recorded as translation adjustments in other
comprehensive  income  /  loss.  The  exchange  differences  arising  on  translation  for  consolidation  are  recognized  in
“accumulated  other  comprehensive  income  /  loss”.  On  disposal  of  a  foreign  operation,  the  component  of  other
comprehensive income / loss relating to that foreign operation is recognized in profit or loss.

2.3.4      Fair value measurement

The Company measures certain assets and liabilities at fair value, either upon initial recognition or for subsequent
accounting or reporting. ASC 820, Fair Value Measurements and Disclosures requires disclosure of methodologies used in
determining the reported fair values and establishes a hierarchy of inputs used when available. The three levels of the fair
value hierarchy are described below:

● Level 1 - Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that

the Company can access at the measurement date.

● Level 2 - Valuations based on quoted prices for similar assets or liabilities in markets that are not active or

models for which the inputs are observable, either directly or indirectly.

● Level 3 - Valuations that require inputs that reflect the Company’s own assumptions that are both significant

to the fair value measurement and are unobservable.

To the extent that valuation is based on models or inputs that are less observable or unobservable in the market,
the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in
determining fair value is greatest for instruments categorized as Level 3. A financial instrument’s level within the fair value
hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

Items measured at fair value on a recurring basis include financial instruments and contingent consideration (Note
5, “Fair value measurement”). The carrying amount of cash and cash equivalents, accounts receivable from collaborators,
prepaid expenses, other assets, accounts payable, accrued expenses and other current liabilities reflected in the consolidated
balance sheets approximate their fair values due to their short-term maturities.

2.3.5      Corlieve transaction

On  July  30,  2021  (“Acquisition  Date”),  the  Company  acquired  Corlieve.  The  Company  evaluated  the  Corlieve
transaction  as  to  whether  or  not  the  transaction  should  be  accounted  for  as  a  business  combination  or  asset  acquisition.
Refer to Note 3 “Corlieve transaction” for further detail.

a. Goodwill

Goodwill  represents  the  excess  of  the  fair  value  of  the  consideration  transferred  over  the  fair  value  of  the  net
assets assumed in a business combination. Goodwill is not amortized but is evaluated for impairment on an annual basis
and between annual tests if we become aware of any events occurring or changes in circumstances that would more likely
than not reduce the fair value of the reporting unit below its carrying amount. As of December 31, 2021, the Company has
not recognized any impairment charges related to goodwill.

Refer to Note 3 “Corlieve transaction” for further detail.

b. Acquired research and development

The Company identified various licenses that combined with the results of the research and development activities
conducted  in  relation  to  AMT-260  since  incorporation  of  Corlieve  in  2019  constitute  an  In-process  research  and
development  intangible  asset  (“IPR&D  Intangible  Asset”).  The  IPR&D  Intangible  Asset  is  considered  to  be  indefinite-
lived until the completion or abandonment of the associated research and development efforts and is not amortized. If and
when  development  is  completed,  which  generally  occurs  when  regulatory  approval  to  market  a  product  is  obtained,  the
associated asset would be deemed finite-lived and would then be amortized based on its respective useful life at that point
in  time.  As  of  December  31,  2021,  the  Company  has  not  recognized  any  impairment  charges  related  to  the  IPR&D
Intangible Asset.

In case of abandonment, the IPR&D Intangible Asset will be written-off. In accordance with ASC 350, Intangibles
– Goodwill and Other, the Company tests indefinite-lived intangible assets for impairment on an annual basis and between
annual tests if the Company becomes aware of any events occurring or changes in circumstances that would indicate the
fair value of the IPR&D Intangible Asset is below its carrying amount.

Refer to Note 3 “Corlieve transaction” for further detail.

c. Contingent consideration

Each  reporting  period,  the  Company  revalues  the  contingent  consideration  obligations  associated  with  the
Corlieve  transaction  to  their  fair  value  and  records  changes  in  the  fair  value  within  research  and  development  expenses.
Changes  in  contingent  consideration  result  from  changes  in  assumptions  regarding  the  probabilities  of  achieving  the
relevant milestones, or probability of success (“POS”), the estimated timing of achieving such  milestones, and the interest
rate to discount the payments. Payments made soon after the acquisition date are recorded as cash flows from financing
activities, and payments, or the portion of the payments, not made soon after the acquisition date are recorded as cash flows
from operating activities.

Refer to Note 3 “Corlieve transaction” for further detail.

2.3.6      Notes to the consolidated statements of cash flows

The consolidated statements of cash flows have been prepared using the indirect method. The cash disclosed in
the  consolidated  statements  of  cash  flows  is  comprised  of  cash  and  cash  equivalents.  Cash  and  cash  equivalents  include
bank balances, demand deposits and other short-term highly liquid investments (with maturities of less than three months at
the time of purchase) that are readily convertible into a known amount of cash and are subject to an insignificant risk of
fluctuation in value.

Cash  flows  denominated  in  foreign  currencies  have  been  translated  at  the  average  exchange  rates.  Exchange
differences, if any, affecting cash and cash equivalents are shown separately in the consolidated statements of cash flows.
Interest paid and received, and income taxes are included in net cash (used in) provided by operating activities.

2.3.7      Segment information

Operating  segments  are  identified  as  a  component  of  an  enterprise  for  which  separate  discrete  financial
information  is  available  for  evaluation  by  the  chief  operating  decision  maker,  or  decision-making  group,  in  making
decisions  on  how  to  allocate  resources  and  assess  performance.  The  Company  views  its  operations  and  manages  its
business  as  one  operating  segment,  which  comprises  the  discovery,  development,  and  commercialization  of  innovative
gene therapies.

2.3.8      Net income / (loss) per share

The Company follows the provisions of ASC 260, Earnings Per Share. In accordance with these provisions, net
income / (loss) per share is calculated by dividing net income / (loss) by the weighted average number of ordinary shares
outstanding during the period.

Diluted net income / (loss) per share reflects the dilution that would occur if share options or warrants to issue
ordinary shares were exercised, performance or restricted share units were distributed, or shares under the employee share
purchase plan were issued. However, potential ordinary shares are excluded if their effect is anti-dilutive.

Refer to Note 16 “Basic and diluted earnings per share” for further information.

2.3.9      Impairment of long-lived assets

Long-lived  assets,  which  include  property,  plant,  and  equipment  and  finite-lived  intangible  assets,  are  reviewed
for impairment whenever events or changes in circumstances indicate that the carrying value of an asset or asset group may
not be recoverable. Right-of-use assets are also reviewed for impairment in accordance with ASC 360, Property, Plant, and
Equipment. The recoverability of the carrying value of an asset or asset group depends on the successful execution of the
Company’s business initiatives and its ability to earn sufficient returns on approved products and product candidates. When
such events or changes in circumstances occur, the Company assesses recoverability by determining whether the carrying
value of such assets will be recovered through the undiscounted expected future cash flows. If the future undiscounted cash
flows are less than the carrying amount of these assets, the Company recognizes an impairment loss based on the excess of
the carrying value over the fair value of the assets. Fair value is determined through various valuation techniques, including
discounted cash flow models, quoted market values, and third-party independent appraisals, as considered necessary. The
Company performs the same quantitative analysis discussed above for long-lived assets and finite-lived intangible assets

Refer to Note 2.3.5 “Corlieve transaction” for information on impairment testing related to goodwill and acquired

research and development intangible assets.

2.3.10    Property, plant, and equipment

Property,  plant,  and  equipment  is  comprised  mainly  of  laboratory  equipment,  leasehold  improvements,
construction-in-progress (“CIP”) and office equipment. All property, plant and equipment is stated at cost less accumulated
depreciation.  CIP  consists  of  capitalized  expenses  associated  with  construction  of  assets  not  yet  placed  into  service.
Depreciation commences on CIP once the asset is placed into service based on its useful life determined at that time.

Maintenance and repairs that do not improve or extend the lives of the respective assets are expensed as incurred.
Upon disposal, the related cost and accumulated depreciation is removed from the accounts and any resulting gain or loss
on the transaction is recognized in the consolidated statements of operations and comprehensive loss.

Depreciation  is  calculated  using  the  straight-line  method  over  the  estimated  useful  lives  of  the  assets  (or  in  the

case of leasehold improvements a shorter lease term), which are as follows:

·    Leasehold improvements
·    Laboratory equipment
·    Office equipment

    Between 10 – 15 years

5 years
Between 3 – 5 years

2.3.11    Leases

The Company adopted ASC 842, Leases using the modified retrospective approach with an effective date as of the

beginning of the Company’s fiscal year, January 1, 2019, to operating leases that existed on that date.

The Company measured lease liabilities at the present value of the future lease payments as of January 1, 2019.
The Company used an incremental borrowing rate to discount the lease payments. The Company derived the discount rate,
adjusted  for  differences  such  as  in  the  term  and  payment  patterns,  from  the  Company’s  loan  from  Hercules  Technology
Growth Capital, Inc (“Hercules Capital”), which was refinanced immediately prior to the January 1, 2019 adoption date in
December 2018. The right-of-use asset is valued at the amount of the lease liability reduced by the remaining December
31, 2018 balance of lease incentives received. The lease liability is subsequently measured at the present value of the future
lease  payments  as  of  the  reporting  date  with  a  corresponding  adjustment  to  the  right-to-use  asset.  Absent  a  lease
modification, the Company will continue to utilize the January 1, 2019, incremental borrowing rate.

For leases recognized after the adoption date, the Company determines if an arrangement is a lease at inception.
Operating  lease  right-of-use  assets  and  lease  liabilities  are  initially  recognized  based  on  the  present  value  of  future
minimum  lease  payments  over  the  lease  term  at  commencement  date  calculated  using  an  incremental  borrowing  rate
applicable  to  the  lease  asset,  unless  the  implicit  rate  is  readily  available.  Lease  terms  may  include  options  to  extend  or
terminate the lease when it is reasonably certain that the Company will exercise that option. Leases with a term of twelve
months or less are not recognized on the consolidated balance sheets.

The Company recognizes lease cost on a straight-line basis and presents these costs as operating expenses within
the  Consolidated  statements  of  operations  and  comprehensive  loss.  The  Company  presents  lease  payments  within  cash
flows from operations within the Consolidated statements of cash flows.

2.3.12    Other (non) current assets

Deposits paid are either presented as other current assets or as other non-current assets based on duration of the

underlying contractual arrangement. Deposits are classified as restricted cash and primarily relate to facility leases.

Contract assets are presented in other current assets or as other non-current assets based on the timing of the right

to consideration.

2.3.13    Prepaid expenses

Prepaid  expenses  are  amounts  paid  in  the  period,  for  which  the  benefit  has  not  been  realized,  and  include
payments made for insurance and research and clinical contracts. The related expense will be recognized in the subsequent
period as incurred.

2.3.14 Accounts receivable

Accounts receivables include amounts due from services provided to the Company’s licensing and collaboration

partners as well as unconditional rights to consideration from its licensing and collaboration partners.

2.3.15    Accounts payable and accrued expenses

Accounts  payables  are  invoiced  amounts  related  to  obligations  to  pay  for  goods  or  services  that  have  been
acquired in the ordinary course of business from suppliers. Accounts payables are recognized at the amounts invoiced by
suppliers.

Accrued expenses are recognized for goods or services that have been acquired in the ordinary course of business.

Contract liabilities are presented in accounts payable and accrued expenses.

119

Table of Contents

2.3.16    Long-term debt

Long-term debt is initially recognized at cost and presented net of original issue discount or premium and debt
issuance costs on the consolidated balance sheets. Amortization of debt discount and debt issuance costs is recognized as
interest expense in profit and loss over the period of the debt, using the effective interest rate method.

2.3.17    Pensions and other post-retirement benefit plans

The  Company  has  a  defined  contribution  pension  plan  for  all  employees  at  its  Amsterdam  facility  in  the
Netherlands, which is funded by the Company through payments to an insurance company, with individual accounts for
each participants’ assets. The Company has no legal or constructive obligation to pay further contributions if the plan does
not hold sufficient assets to pay all employees the benefits relating to services rendered in the current and prior periods.
The contributions are expensed as incurred. Prepaid contributions are recognized as an asset to the extent that a cash refund
or a reduction in the future payments is available.

In 2016, the Company adopted a qualified 401(k) Plan for all employees located in the United States. The 401(k)
Plan  offers  both  a  pre-tax  and  post-tax  (Roth)  component.  Employees  may  contribute  up  to  the  IRS  statutory  limit  each
calendar  year.  The  Company  matches  $0.50  for  every  $1.00  contributed  to  the  plan  by  participants  up  to  6%  of  base
compensation. Employer contributions are recognized as they are contributed, as long as the employee is rendering services
in that period. If employer contributions are made in periods after an individual retires or terminates, the estimated cost is
accrued during the employee’s service period.

2.3.18    Share-based compensation

The  Company  accounts  for  its  share-based  compensation  awards  in  accordance  with  ASC  718,  Compensation-

Stock Compensation.

All  the  Company’s  share-based  compensation  plans  for  employees  are  equity-classified.  ASC  718  requires  all
share-based  compensation  to  employees,  including  grants  of  employee  options,  restricted  share  units,  performance  share
units  and  modifications  to  existing  instruments,  to  be  recognized  in  the  consolidated  statements  of  operations  and
comprehensive  loss  based  on  their  grant-date  fair  values,  net  of  an  estimated  forfeiture  rate,  over  the  requisite  service
period. Forfeitures of employee options are recognized as they occur. Compensation expense related to Performance Share
Units is recognized when the Company considers achievement of the milestones to be probable. The requirements of ASC
718 are also applied to nonemployee share-based payment transactions except for specific guidance on certain inputs to an
option-pricing model and the attribution of cost.

The Company uses a Hull & White option model to determine the fair value of option awards. The model captures
early exercises by assuming that the likelihood of exercises will increase when the share-price reaches defined multiples of
the strike price. This analysis is performed over the full contractual term.

2.3.19    Revenue recognition

The Company primarily generates revenue from its commercialization and license agreement with CSL Behring
and its collaboration, research, and license agreements with BMS for the development and commercialization of product
candidates.

CSL Behring collaboration

On  June  24,  2021  (“Signing  Date”),  the  Company  entered  into  a  commercialization  and  license  agreement
pursuant to which CSL Behring received exclusive global rights to etranacogene dezaparvovec (“Product”). The Company
concluded  that  CSL  Behring  is  a  customer  in  accordance  with  ASC  606,  Revenue  from  Contracts  with  Customers  and
identified two material performance obligations related to the CSL Behring Agreement:

(i) Sale of the exclusive global rights to the Product (“License Sale”); and

(ii) Generate  information  to  support  the  regulatory  approval  of  the  current  and  next  generation  manufacturing
process  of  Product  and  to  provide  any  such  information  generated  to  CSL  Behring  (“Manufacturing
Development”).

120

Table of Contents

These  performance  obligations  are  considered  distinct  from  one  another,  as  CSL  Behring  can  benefit  from  the
identified service either on its own or together with other resources that are readily available to CSL Behring, and as the
performance obligations are separately identifiable from other performance obligations in the CSL Behring Agreement.

Refer to Note 4 “Collaboration arrangements and concentration of credit risk” for further detail.

Bristol-Myers Squib collaboration

The  Company  initially  entered  into  collaboration,  research,  and  license  agreements  with  BMS  in  2015  and

amended them in 2020.

The Company evaluated the initial BMS CLA and determined that its performance obligations were as follows:

● Providing pre-clinical research activities (“Collaboration Revenue”);

● Providing clinical and commercial manufacturing services for products (“Manufacturing Revenue”); and

● Providing access to its technology and know-how in the field of gene therapy as well as actively contributing
to  the  target  selection,  the  collaboration  as  a  whole,  the  development  during  the  target  selection,  the  pre-
clinical and the clinical phase through participating in joint steering committee and other governing bodies
(“License Revenue”).

As further discussed in Note 4, “Collaboration arrangements and concentration of credit risk”, as a result of the
December 2020 amended BMS CLA, the Company’s performance obligation related to License Revenues was materially
completed  as  of  the  date  of  the  amendment  effective  date  of  December  1,  2020.  The  Company  may  still  be  required  to
provide pre-clinical research activities or clinical and commercial manufacturing services when BMS exercises its options
for those services.

License Revenue

Until  the  December  2020  amendment  of  the  BMS  CLA  the  Company  recognized  License  Revenue  over  the
expected  performance  period  based  on  its  measure  of  progress  towards  the  completion  of  certain  activities  related  to  its
services.  Following  the  December  2020  amendment  of  the  BMS  CLA  the  Company’s  performance  was  materially
completed and it had satisfied its performance obligation (see Note 4, “Collaboration arrangements and concentration of
credit risk”, for a detailed discussion).

Collaboration and Manufacturing Revenue

The Company recognizes Collaboration Revenues associated with optional work orders it receives from BMS to
provide analytical development and process development activities that are reimbursable by BMS in accordance with the
BMS CLA as well as the amended BMS CLA.

BMS  and  the  Company  entered  into  a  Master  Clinical  Supply  Agreement  in  April  2017  for  the  Company  to
supply gene therapy products during the clinical phase as well as into a binding term sheet to supply gene therapy products
during  the  commercial  phase  to  BMS.  In  December  2020,  BMS  and  the  Company  also  entered  into  a  Research  Supply
Agreement. Revenues from product sales will be recognized when earned. The Company will provide these services as it
receives optional work orders from BMS in relation to such services.

2.3.20    Other income, other expense

The  Company  receives  certain  government  and  regional  grants,  which  support  its  research  efforts  in  defined
projects,  and  include  contributions  towards  the  cost  of  research  and  development.  These  grants  generally  provide  for
reimbursement  of  approved  costs  incurred  as  defined  in  the  respective  grants  and  are  deferred  and  recognized  in  the
statements of operations and comprehensive loss over the period necessary to match them with the costs they are intended
to  compensate,  when  it  is  probable  that  the  Company  has  complied  with  any  conditions  attached  to  the  grant  and  will
receive the reimbursement.

121

Table of Contents

The  Company’s  other  income  also  consists  of  employee  retention  credits  received  under  the  U.S.  Coronavirus
Aid,  Relief,  and  Economic  Security  Act,  income  related  to  a  settlement  agreement  that  the  Company  and  VectorY  B.V.
entered into in April 2021, as well as income from subleasing part of the Company’s Amsterdam facility. Other expense
consists of expenses incurred in relation to the subleasing income.

2.3.21    Research and development expenses

Research and development costs are expensed as incurred. Research and development expenses generally consist
of  laboratory  research,  clinical  trials,  statistical  analysis,  and  report  writing,  regulatory  compliance  costs  incurred  with
clinical research organizations and other third-party vendors (including post-approval commitments to conduct consistency
and comparability studies). In addition, research and development expenses consist of start-up and validation costs related
to  the  Company’s  Lexington  facility  and  the  development  and  improvement  of  the  Company’s  manufacturing  processes
and  methods.  Furthermore,  research  and  development  costs  include  costs  of  materials  and  costs  of  intangible  assets
purchased  from  others  for  use  in  research  and  development  activities.  The  costs  of  intangibles  that  are  purchased  from
others  for  a  particular  research  and  development  project  and  that  have  no  alternative  future  uses  (in  other  research  and
development projects or otherwise) are expensed as research and development costs at the time the costs are incurred or at
the time when no alternative future use is identified.

2.3.22    Income taxes

Income taxes are recorded in accordance with ASC 740, Income Taxes, which provides for deferred taxes using an
asset  and  liability  approach.  The  Company  recognizes  deferred  tax  assets  and  liabilities  for  the  expected  future  tax
consequences of events that have been included in the financial statements or tax returns. Deferred tax assets and liabilities
are determined based on the difference between the financial statement carrying amount and the tax bases of assets and
liabilities  using  enacted  tax  rates  in  effect  for  the  year  in  which  the  differences  are  expected  to  reverse.  Valuation
allowances  are  provided,  if  based  upon  the  weight  of  available  evidence,  it  is  more-likely-than-not  that  some  or  all  the
deferred tax assets will not be realized.

The benefits of tax positions are recognized only if those positions are more likely than not, based on the technical
merits, to be sustained upon examination. Recognized tax positions are measured at the largest amount of tax benefit that is
greater than 50 percent likely of being realized upon settlement. The determination as to whether the tax benefit will more-
likely-than-not be realized is based upon the technical merits of the tax position as well as consideration of the available
facts and circumstances. As of December 31, 2021, and 2020, the Company did not have any significant unrecognized tax
benefits.

2.3.23 Recently Adopted Accounting Pronouncements

Recent Accounting Pronouncements Not Yet Effective

ASU 2021-10: Government Assistance

In  November  2018,  the  FASB  issued  ASU  2021-10,  Government  Assistance  (Topic  832)  which  discusses  the
requirements for disclosures related to transactions with a government. ASU 2021-10 is effective for fiscal years beginning
after December 15, 2021. The new disclosure requirements will require disclosures around 1) information about the nature
of the transactions and the related accounting policy used to account for the transactions, 2) the line items on the balance
sheet and income statement that are affected by the transactions, and the amounts applicable to each financial statement
line item, and 3) significant terms and conditions of the transactions, including commitments and contingencies. An entity
should  apply  the  updates  prospectively  or  retrospectively.  The  Company  currently  includes  information  on  government
grants  and  does  not  expect  these  amendments  to  have  a  material  impact  on  the  Company’s  consolidated  financial
statements.

Corlieve transaction

At  the  Acquisition  Date,  the  Company  acquired  Corlieve.  Following  Corlieve’s  formation  in  November  2019,
Corlieve obtained exclusive licenses to certain patents from two French research institutions that continue to collaborate
with the Company. Corlieve also obtained an exclusive license from Regenxbio Inc. (“Regenxbio”) to use AAV9 to deliver
any  sequence  that  affects  the  expression  of  the  Glutamate  inotropic  receptor  kainate  type  subunit  2  (“GRIK  2”)  gene
sequence  in  humans.  Corlieve  and  Regenxbio  simultaneously  entered  into  a  collaboration  plan  related  to  agreed  joint
preclinical  research  and  development  activities.  At  the  Acquisition  Date,  Corlieve  and  its  Swiss  subsidiary,  Corlieve
Therapeutics AG, employed seven employees. Corlieve’s result for the full year 2021 was a $7.3 million loss. The result
included in the Company’s consolidated results for the year ended December 31, 2021 is a $4.1 million loss.

The Company evaluated the Corlieve transaction as to whether or not the transaction should be accounted for as a
business combination or asset acquisition by first applying a screen test to determine if substantially all of the fair value of
the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. Based on the
fair  values  of  the  gross  assets  acquired,  the  Company  determined  the  screen  test  was  not  met.  The  Company  further
analyzed whether or not the acquired inputs and processes that have the ability to create outputs would meet the definition
of a business. Significant judgment is required in the application of the screen test to determine whether an acquisition is a
business combination or an acquisition of assets.

Identifiable  assets  and  liabilities  of  Corlieve,  including  identifiable  intangible  assets,  were  recorded  at  their  fair
values as of the Acquisition Date, when the Company obtained control. The excess of the fair value of the consideration
transferred over the fair value of the net assets acquired was recorded as goodwill.

The  following  table  summarizes  the  fair  values  assigned  to  assets  acquired  and  the  liabilities  assumed  by  the

Company, along with the resulting goodwill, as of the Acquisition Date:

Consideration

On the Acquisition Date, the Company acquired 97.7% of the outstanding ordinary shares of Corlieve in return for
EUR  44.9  million  ($53.3  million  as  of  the  Acquisition  Date).  As  is  contractually  required  the  Company  acquired  the
remaining  outstanding  ordinary  shares  on  February  9,  2022  following  the  expiration  of  a  minimum  holding  period.  The
Company  recorded  a  liability  related  to  these  Mandatorily  Redeemable  Shares  for  an  amount  of  EUR  0.7  million  ($0.9
million) as of the Acquisition Date. The Company financed the Corlieve Transaction from its cash on hand.

123

Table of Contents

In addition to the payments to acquire 100% of the outstanding ordinary shares, Corlieve’s former shareholders
are  eligible  to  receive  up  to  EUR  35.8  million  ($40.6  million  as  of  December  31,  2021)  upon  achievement  of  certain
development  milestones  through  Phase  I/II  and  EUR  143.1  million  ($162.3  million  as  of  December  31,  2021)  upon
achievement  of  certain  milestones  associated  with  Phase  III  development  and  obtaining  approval  to  commercialize
Corlieve’s  target  candidate  for  the  treatment  of  temporal  lobe  epilepsy  (“AMT-260”  or  “TLE”)  in  the  United  States  of
America  and  the  European  Union.  The  Company  may  elect  to  pay  up  to  25%  of  such  milestone  payments  through  the
issuance of the Company’s ordinary shares.

As  of  the  Acquisition  Date,  the  Company  recorded  EUR  20.2  million  ($24.0  million)  as  a  contingent  liability
(presented  as  “Non-current  liability”)  for  the  fair  value  of  these  milestone  payments.  The  fair  value  of  the  contingent
liability as of December 31, 2021 amounted to EUR 26.0 million ($29.5 million). Changes in fair value of the contingent
liability are recognized within research and development expenses in the consolidated statements of operations.

Identified intangible assets

The Company identified various licenses that combined with the results of the research and development activities
conducted  in  relation  to  AMT-260  since  incorporation  of  Corlieve  in  2019  constitute  an  In-process  research  and
development intangible asset (“IPR&D Intangible Asset”).

The  Company  determined  the  fair  value  of  the  IPR&D  Intangible  Asset  using  a  present  value  model  based  on
expected cash flows. Estimating the amounts and timing of cash flows required to complete the development of AMT-260
as well as net sales, cost of goods sold, and sales and marketing costs involved considerable judgment and uncertainty. The
expected  cash  flows  are  materially  impacted  by  the  probability  of  successfully  completing  the  various  stages  of
development  (i.e.,  dosing  of  first  patient  in  clinical  trial,  advancing  into  late-stage  clinical  development  and  obtaining
approval to commercialize a product candidate) as well as the weighted average cost of capital of 10.4% used to discount
the  expected  cash  flows.  Based  on  all  such  information  and  its  judgment  the  Company  estimated  the  fair  value  of  the
IPR&D Intangible Asset at EUR 53.6 million ($63.6 million) as of the Acquisition Date.

Deferred tax liability, net

Corlieve’s deferred tax assets at the time of acquisition amounted to EUR 1.5 million ($1.7 million). Recognition
of  the  IPR&D  Intangible  Asset  gave  rise  to  a  deferred  tax  liability  of  EUR  13.4  million  ($15.9  million)  at  the  enacted
French corporate income tax rate of 25.0%. The Company consequently recorded a net deferred tax liability of EUR 11.9
million ($14.2 million as of the Acquisition Date). Changes in the net deferred tax liability after the Acquisition Date will
be recorded in income tax expense in the consolidated statements of operations.

Goodwill

Goodwill  represents  the  excess  of  total  consideration  over  the  estimated  fair  value  of  net  assets  acquired.  The
Company recorded EUR 23.9 million ($28.4 million) of goodwill in the consolidated balance sheet as of the Acquisition
Date. The goodwill primarily relates to the recognition of a deferred tax liability recognized in association with the IPR&D
Intangible  asset  of  EUR  13.4  million  ($15.9  million  as  of  Acquisition  Date)  as  well  as  the  fair  market  value  of  the
experienced workforce and potential synergies from the acquisition. The Company allocated the goodwill to its reporting
unit. The Company does not expect any portion of this goodwill to be deductible for income tax purposes.

Debt

As of the Acquisition Date, Corlieve held a loan with outstanding amount equal to EUR 1.0 million ($1.2 million),
which  loan  was  repaid  in  its  entirety  in  September  2021.  As  of  the  Acquisition  Date,  Corlieve  also  held  a  loan  with
outstanding amount equal to EUR 0.4 million ($0.4 million), which was repaid in its entirety in December 2021.

Other

As of the Acquisition Date, the Company also acquired other assets and assumed other liabilities, which included
among others, EUR 2.9 million ($3.4 million) of current assets, which consisted of EUR 2.8 million ($3.3 million) of cash,
and EUR 1.1 million ($1.3 million) of current liabilities.

4.            Collaboration arrangements and concentration of credit risk

CSL Behring collaboration

On the Signing Date, uniQure biopharma B.V., a wholly-owned subsidiary of uniQure N.V., entered into the CSL
Behring Agreement with CSL Behring, pursuant to which CSL Behring received exclusive global rights to the Product. On
May 6, 2021, a day after the expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of
1976, the CSL Behring Agreement became fully effective (“Closing”).

Pursuant to the CSL Behring Agreement, the Company received a $450.0 million upfront cash payment and $12.4
million in other payments related to the Closing and the transfer of the license. The Company is eligible to receive up to
$1.6 billion in additional payments based on the achievement of regulatory and commercial milestones. The CSL Behring
Agreement also provides that the Company will be eligible to receive tiered double-digit royalties in a range of up to a low-
twenties percent of net sales of the Product based on sales thresholds.

On  the  Signing  Date,  the  Company  and  CSL  Behring  entered  into  a  development  and  commercial  supply
agreement, pursuant to which, among other things, the Company will supply the Product to CSL Behring at an agreed-upon
price commensurate with the SSP. The Company will be responsible for supplying development and commercial Product
until  such  time  that  these  capabilities  may  be  transferred  to  CSL  Behring  or  a  designated  contract  manufacturing
organization. The Company will be completing the HOPE-B clinical trial and the validation of the manufacturing process
on behalf of CSL Behring, as well as provide further development services if requested by CSL Behring. Activities related
to  on-demand  development  services  as  well  as  activities  related  to  the  completing  the  HOPE-B  clinical  trial  will  be
reimbursed  by  CSL  Behring  at  an  agreed  full-time-employee  rate  (“FTE-rate”)  and  CSL  Behring  will  also  reimburse
agreed third-party expenses incurred in relation to performing these activities. The validation of the manufacturing process
as well as Manufacturing Development will be reimbursed through a future milestone payment. If completed after certain
contractually agreed upon dates, the milestone payment will be reduced in accordance with a pre-specified mechanism.

The Company concluded that CSL Behring is a customer in accordance with Topic 606.

The Company identified two material performance obligations related to the CSL Behring Agreement:

(i)

(ii)

License Sale; and

Manufacturing Development.

These  performance  obligations  are  considered  distinct  from  one  another,  as  CSL  Behring  can  benefit  from  the
identified service either on its own or together with other resources that are readily available to CSL Behring, and as the
performance  obligations  are  separately  identifiable  from  other  performance  obligations  in  the  CSL  Behring  Agreement.
The Company continued to develop the Product between the Signing Date and Closing and performed certain reimbursable
activities  to  fulfill  the  transfer  of  the  global  rights  (“Additional  Covenants”  and  together  with  the  License  the  “License
Sale”). The Additional Covenants are not considered distinct from the performance obligation to sell the license to CSL
Behring  as  CSL  Behring  could  not  benefit  from  the  Additional  Covenants  on  their  own,  or  have  these  activities  be
performed with readily available resources.

The  Company  determined  that  the  fixed  upfront  payment  of  $450.0  million  and  the  $12.4  million  that  the
Company  received  in  relation  to  the  Additional  Covenants  should  be  allocated  to  the  License  Sale.  In  addition,  the
Company concluded that variable milestone payments, sales milestone payments and royalties should be allocated to the
License Sale performance obligation as well. The Company determined that the License Sale was completed on May 6,
2021,  when  it  transferred  the  license  and  CSL  Behring  assumed  full  responsibility  for  the  development  and
commercialization  of  the  Product.  At  Closing,  the  Company  evaluated  the  amounts  of  potential  payments  and  the
likelihood  that  the  payments  will  be  received.  The  Company  utilized  the  most  likely  amount  method  to  estimate  the
variable  consideration  to  be  included  in  the  transaction  price.  Since  the  Company  cannot  control  the  achievement  of
regulatory and first commercial sales milestones, the Company concluded that the potential payments are constrained as of
Closing.  The  Company  determined  that  it  would  recognize  revenue  related  to  these  payments  only  to  the  extent  that  it
becomes probable that no significant reversal of recognized cumulative revenue will occur thereafter.

Similarly,  the  Company  will  record  expenses  related  to  its  existing  license  and  other  agreements  as  well  as  its
financial advisor for a high single digit percentage of any such revenue recognized associated to meeting a milestone. The
Company  will  include  payments  related  to  sales  milestones  in  the  transaction  price  when  their  achievement  becomes
probable, and it will include royalties on the sale of Product once these have been earned. The Company determined that
achievement of a total of $55.0 million of milestone payments related to the submissions of a biologics license application
(“BLA”) and market authorization application (“MAA”) is probable as of the time of filing these financial statements and
hence recorded these as license revenue in the year ended December 31, 2021. In making the determination, the Company
considered that after Closing, it believes to successfully have completed the validation of its manufacturing process for the
Product in December 2021 and that CSL Behring announced the accomplishment of the primary clinical endpoint for the
Product in December 2021. The Company recognized $517.4 million of revenues related to the License Sale in the year
ended December 31, 2021.

The Company determined that the variable milestone payment related to Manufacturing Development should be
allocated to the Manufacturing Development performance obligation. The Company concluded that this milestone payment
represents the SSP of the services based on the estimated cost of providing the services including a reasonable margin. The
services  related  to  Manufacturing  Development  will  be  provided  between  Closing  and  the  completion  of  an  agreed
manufacturing  development  plan.  The  variable  consideration  will  be  reduced  if  the  Company  does  not  complete  the
development  by  pre-agreed  dates.  The  Company  utilized  the  most  likely  amount  method  to  estimate  the  variable
consideration to be included in the transaction price. Completion of Manufacturing Development is partially dependent on
the  timing  of  regulatory  submissions  by  CSL  Behring  as  well  as  regulatory  approvals  of  the  developed  manufacturing
processes. Since the Company cannot control the timing or outcome of any regulatory decisions, the Company concluded
that it would recognize revenue related to this payment when it becomes probable that the milestone has been achieved.
The Company has not recognized any revenue related to Manufacturing Development.

The  Company  recognized  $2.4  million  of  collaboration  revenue  in  the  year  ended  December  31,  2021,
respectively, compared to nil in the same periods in 2020 and 2019. The Company generates such collaboration revenue
from services rendered in relation to completing the HOPE-B clinical trial on behalf of CSL Behring. CSL Behring may
request  additional  development  services  or  request  the  Company  to  support  the  transfer  of  manufacturing  to  a  party
designated  by  CSL  Behring.  These  collaboration  services  will  be  reimbursed  at  the  pre-agreed  FTE-rate.  The  Company
concluded that these rights at Closing do not represent material rights.

The Company incurred $2.1 million of expenses for obligations related to the CSL Behring Agreement that had
not  been  satisfied  as  of  December  31,  2020.  The  Company  capitalized  these  expenses  as  contract  fulfillment  costs
(presented within Other current assets). As of December 31, 2020, the Company also recognized a $2.1 million receivable
(presented within Accounts receivable) from CSL Behring for expenses for which it has a right of reimbursement as well
as a contract liability (presented within Accrued expenses and other current liabilities) for the same amount. In accordance
with ASC 606 the Company could not recognize any license revenue related to the CSL Behring Agreement in the period
ended December 31, 2020. Following the Closing, the Company collected the $2.1 million of accounts receivable related to
reimbursable  contract  fulfillment  costs  that  was  outstanding  as  of  December  31,  2020.  As  of  December  31,  2021,  the
Company has recorded accounts receivable of $2.9 million from CSL Behring related to clinical development services as
well as a contract asset of $55.0 million related to BLA and MAA submission milestone payments considered probable.

Bristol-Myers Squibb collaboration

2015 Agreement

In  May  2015,  the  Company  entered  into  the  BMS  CLA  and  various  related  agreements  with  BMS,  which  the
Company  collectively  refers  to  as  the  BMS  CLA,  which  provided  BMS  with  exclusive  access  to  the  Company’s  gene
therapy  technology  platform  for  the  research,  development  and  commercialization  of  therapeutics  aimed  at  multiple
Collaboration Targets. The initial four-year research term under the collaboration terminated on May 21, 2019. During the
initial  research  term  of  the  BMS  CLA,  the  Company  supported  BMS  in  discovery,  non-clinical,  analytical  and  process
development  efforts  in  respect  of  the  Collaboration  Targets.  For  any  Collaboration  Targets  that  may  be  advanced,  the
Company will be responsible for manufacturing of clinical and commercial supplies. BMS reimbursed the Company for all
its research and development costs in support of the collaboration, and will lead development, regulatory and commercial
activities  for  any  Collaboration  Targets  that  may  be  advanced.  The  BMS  CLA  initially  provided  that  the  Company  and
BMS could potentially have collaborated on up to ten Collaboration Targets in total.

2020 Amendment

On December 1, 2020, the Company and BMS entered into the amended BMS CLA. Under the amended BMS
CLA, BMS is limited to four Collaboration Targets. For a period of one-year from the effective date of the amended BMS
CLA,  BMS  was  able  to  replace  up  to  two of the four  active  Collaboration  Targets  with  two  new  targets  in  the  field  of
cardiovascular disease. The Company continues to be eligible to receive research, development, and regulatory milestone
payments of up to $217.0 million for each Collaboration Target, if defined milestones are achieved.

Since  the  December  2020  amendment,  BMS  is  no  longer  entitled  to  designate  the  fifth  to  tenth  Collaboration
Targets  and  as  such  the  Company’s  remaining  obligations  under  the  amended  BMS  CLA  are  substantially  reduced.  The
Company  is  also  no  longer  entitled  to  receive  up  to  an  aggregate  $16.5  million  in  target  designation  payments  for  the
research, development and regulatory milestone payments associated with the fifth to tenth Collaboration Targets.

For as long as any of the four Collaboration Targets are being advanced, BMS may place a purchase order to be
supplied with research, clinical and commercial supplies. Subject to the terms of the amended BMS CLA, BMS has the
right  to  terminate  the  research,  clinical  and  commercial  supply  relationships,  and  has  certain  remedies  for  failures  of
supply,  up  to  and  including  technology  transfer  for  any  such  failure  that  otherwise  cannot  be  reasonably  resolved.  Both
BMS  and  the  Company  may  agree  to  a  technology  transfer  of  manufacturing  capabilities  pursuant  to  the  terms  of  the
amended BMS CLA.

The amended BMS CLA does not extend the initial four-year research term that expired in May 2019. BMS may
place purchase orders to provide limited services primarily related to analytical and development efforts in respect of the
four Collaboration Targets. BMS may request such services for a period not to exceed the earlier of (i) the completion of all
activities under a Research Plan and (ii) November 30, 2023, if no replacement targets are designated. BMS continues to
reimburse the Company for these services.

During  the  year  ended  December  31,  2020,  the  Company  evaluated  the  impact  of  the  amendment  of  the  BMS
CLA  had  in  relation  to  its  performance  obligation  related  to  License  Revenue.  The  Company  did  not  identify  any  new
distinct  performance  obligations  and  determined  the  amended  BMS  CLA  did  not  represent  a  separate  contract  in
accordance with ASC 606. The Company evaluated the effect the modification had on its measure of progress towards the
completion  of  its  performance  obligation  related  to  License  Revenue  and  determined  that  its  remaining  performance
obligation under the amended BMS CLA was immaterial and recognized the remaining balance of unrecognized License
Revenue as of November 30, 2020.

The  Company  recognizes  collaboration  revenues  associated  with  Collaboration  Target-specific  pre-clinical
analytical  development  and  process  development  activities  that  are  reimbursable  by  BMS  under  the  BMS  CLA  and  the
amended  BMS  CLA  as  well  as  other  related  agreements.  Collaboration  Revenue  related  to  these  contracted  services  is
recognized when performance obligations are satisfied.

The Company generated $4.2 million collaboration revenue for the year ended December 31, 2021 (December 31,

2020: $0.2 million; December 31, 2019: $2.3 million).

License Revenue

The Company recognized no License Revenue for the year ended December 31, 2021 (December 31, 2020: $33.0

million, December 31, 2019: $5.0 million).

On May 21, 2015, the Company recorded a $60.1 million upfront payment and in August 2015 it recorded a $15.0
million payment it received from BMS in relation to the designation of the second, third and fourth Collaboration Targets.
The  Company  recognized  License  Revenue  over  the  expected  performance  period  based  on  its  measure  of  progress
towards the completion of certain activities related to its services. The Company determined such progress by comparing
activities  performed  at  the  end  of  each  reporting  period  with  total  activities  expected  to  be  performed.  The  Company
estimated total expected activities using several unobservable inputs, such as the probability of BMS designating additional
targets, the probability of successfully completing each phase and estimated time required to provide services during the
various  development  stages.  The  estimation  of  total  services  at  the  end  of  each  reporting  period  involves  considerable
judgment.

The amount of services the Company expects to provide is significantly impacted by the number of Collaboration
Targets  that  it  estimates  BMS  would  pursue.  As  a  result  of  the  December  1,  2020  amendment  of  the  BMS  CLA  the
Company no longer is required to potentially provide any services in relation to six additional targets that BMS might have
designated.  The  Company  determined  its  remaining  performance  obligation  is  immaterial.  The  Company  adjusted  its
measure of progress towards the completion of its activities related to its services as of the December 1, 2020 modification
date accordingly. The Company recognized the remaining balance of unrecognized License Revenue as of November 30,
2020 of $27.8 million in profit and loss during the year ended December 31, 2020 as License Revenue from a related party.

The  Company  includes  variable  consideration  related  to  any  research,  development,  and  regulatory  milestone
payments,  in  the  transaction  price  once  it  is  considered  probable  that  including  these  payments  in  the  transaction  price
would  not  result  in  the  reversal  of  cumulative  revenue  recognized.  Due  to  the  significant  uncertainty  surrounding  the
development of gene-therapy product candidates and the dependence on BMS’s performance and decisions, the Company
does not currently consider this probable. However, there was a milestone that was recorded as license revenue in the year
ended December 31, 2020 (see below).

128

                                                                
    
    
Table of Contents

On  December  17,  2020  BMS  designated  one  of  the  four  Collaboration  Targets  as  a  candidate  to  advance  into
Investigational  New  Drug-enabling  studies  (“IND-enabling  studies”)  entitling  the  Company  to  receive  a  $4.4  million
research milestone payment. The Company recorded the $4.4 million as License Revenue in the year ended December 31,
2020.

The Company recognizes License Revenue related to product sales by BMS from any of the Collaboration Targets
when the sales occur. The Company is eligible to receive net sales-based milestone payments and tiered mid-single to low
double-digit  royalties  on  product  sales.  The  royalty  term  is  determined  on  a  licensed-product-by-licensed-product  and
country-by-country  basis  and  begins  on  the  first  commercial  sale  of  a  licensed  product  in  a  country  and  ends  on  the
expiration of the last to expire of specified patents or regulatory exclusivity covering such licensed product in such country
or, with a customary royalty reduction, ten years after the first commercial sale if there is no such exclusivity.

5.            Fair value measurement and Other non-operating (losses) / gains

The Company measures certain financial assets and liabilities at fair value, either upon initial recognition or for

subsequent accounting or reporting.

The  carrying  amount  of  cash  and  cash  equivalents,  accounts  receivable  from  collaborators,  prepaid  expenses,
other assets, accounts payable, accrued expenses and other current liabilities reflected in the consolidated balance sheets
approximate their fair values due to their short-term maturities.

The  Company’s  only  material  financial  assets  measured  at  fair  value  using  Level  1  inputs  is  cash  and  cash
equivalents  and  restricted  cash.  Restricted  cash  is  included  within  “Other  non-current  assets”  within  the  consolidated
balance sheets.

The following table sets forth the balances and changes in fair values of liabilities that are measured at fair value

using Level 3 inputs:

Pursuant to the BMS CLA, the Company in 2015 granted BMS two warrants that were subsequently terminated in

connection with the amendment to the BMS CLA on December 1, 2020. The Company granted to BMS:

● A warrant that allowed BMS to purchase a specific number of the Company’s ordinary shares such that its
ownership would have equaled 14.9% immediately after such purchase (“1st warrant”). The 1st warrant could
have  been  exercised  on  the  later  of  (i)  the  date  on  which  the  Company  received  from  BMS  the  Target
Designation  Fees  (as  defined  in  the  BMS  CLA)  associated  with  the  first  six  new  targets  (a  total  of  seven
Collaboration  Targets);  and  (ii)  the  date  on  which  BMS  designated  the  sixth  new  target  (the  seventh
Collaboration Target); and

● A warrant that allowed BMS to purchase a specific number of the Company’s ordinary shares such that its
ownership would have equaled 19.9% immediately after such purchase (“2nd warrant” and together with 1st
warrant,  the  “warrants”).  The  warrant  could  have  been  exercised  on  the  later  of  (i)  the  date  on  which  the
Company received from BMS the Target Designation Fees associated with the first nine new targets (a total
of ten  Collaboration  Targets);  and  (ii)  the  date  on  which  BMS  designated  the  ninth  new  target  (the  tenth
Collaboration Target).

On December 1, 2020, the Company derecognized the warrants when these were terminated in accordance with

the amended BMS CLA.

Pursuant to the terms of the BMS CLA the exercise price in respect of each warrant was equal to the greater of (i)
the  product  of  (A)  $33.84,  multiplied  by  (B)  a  compounded  annual  growth  rate  of  10% (or approximately $57.32  as  of
November 30, 2020) and (ii) the product of (A) 1.10 multiplied by (B) the weighted average volume price (“VWAP”) for
the 20 trading days ending on the date that is five trading days prior to the date of a notice of exercise delivered by BMS.

The fair value of the warrants as of December 31, 2019 was $3.1 million. During the year ended December 31,
2020, the Company recognized a $3.1 million gain in non-operating (losses) / gains (December 31, 2019: $2.3 million loss)
related to fair value changes of the BMS warrants. The gain recognized in the year ended December 31, 2020 includes $0.8
million from the derecognition of the BMS warrants on December 1, 2020.

130

Table of Contents

The  Company  used  Monte-Carlo  simulations  to  determine  the  fair  market  value  of  the  BMS  warrants.  The
valuation model incorporated several inputs, the risk-free rate adjusted for the period affected, an expected volatility based
on historical Company volatility, the expected yield on any dividends and management’s expectations on the timelines of
reaching certain defined trigger events for the exercising of the warrants, as well as management’s expectations regarding
the number of ordinary shares that would be issued upon exercise of the warrants. All of these represent Level 3 inputs.
Additionally, the model assumed BMS would exercise the warrants only if it was financially rational to do so.

The  warrants  could  only  have  been  exercised  following  the  occurrence  of  events  contractually  defined  in  the
warrant agreements. The probability of the occurrence of these events represented another significant unobservable input
used in the calculation of the fair value of the warrants.

On  December  1,  2020,  the  Company  and  BMS  agreed  that  upon  the  consummation  of  a  change  of  control
transaction  of  uniQure  that  occurs  prior  to  December  1,  2026  or  BMS’  delivery  of  a  target  cessation  notice  for  all  four
Collaboration  Targets,  the  Company  (or  its  third  party  acquirer)  shall  pay  to  BMS  a  one-time,  non-refundable,  non-
creditable cash payment of $70.0 million, provided that (x) if $70.0 million is greater than five percent (5.0%) of the net
proceeds (as contractually defined) from such change of control transaction, the payment shall be an amount equal to five
percent of such net proceeds, and (y) if $70.0 million is less than one percent of such net proceeds, the change of control
payment  shall  be  an  amount  equal  to  one  percent  of  such  net  proceeds  (“CoC-payment”).  The  Company  has  not
consummated any change of control transaction as of December 31, 2021 that would obligate it to make a CoC-payment.

The  Company  determined  that  the  CoC-payment  should  be  recorded  as  a  derivative  financial  liability  as  of
December  1,  2020  and  that  subsequent  changes  in  the  fair  market  value  of  this  derivative  financial  liability  should  be
recorded in profit and loss. The fair market value of the derivative financial liability is materially impacted by probability
that market participants assign to the likelihood of the occurrence of a change of control transaction that would give rise to
a CoC-payment. This probability represents an unobservable input. The Company determined the fair market value of the
derivative  financial  liability  by  using  a  present  value  model  based  on  expected  cash  flow.  The  expected  cash  flows  are
materially impacted by the probability that market participants assign to the likelihood of the occurrence of a change of
control  transaction  within  the  biotechnology  industry.  The  Company  estimated  this  unobservable  input  using  the  best
information  available  as  of  December  1,  2020,  and  December  31,  2020  and  2021,  respectively.  The  Company  obtained
reasonably available market information that it believed market participants would use in determining the likelihood of the
occurrence  of  a  change-of  control  transaction  within  the  biotechnology  industry.  Selecting  and  evaluating  market
information involves considerable judgment and uncertainty. Based on all such information and its judgment, the Company
estimated that the fair market value of the derivative financial liability (presented within “Other non-current liabilities”) as
of December 31, 2021 was $2.8 million (December 1, 2020 and December 31, 2020: $2.6 million). The Company recorded
a $2.6 million loss within “Other non-operating (losses) / gains” in the year ended December 31, 2020 related to the initial
recognition of this derivative financial liability. The increase of the fair market value of the derivative financial liability of
$0.2 million in the year ended December 31, 2021 was recorded in Other non-operating (losses) / gains.

Hercules loan facility

In  2013  the  Company  entered  into  a  venture  debt  loan  facility  with  Hercules  (see  Note  10,  “Long-term  debt”)
which included a warrant maturing on February 5, 2019. The warrant was not closely related to the host contract and was
accounted  for  separately  as  a  derivative  financial  liability  measured  at  fair  value  though  profit  or  loss.  The  Hercules
warrants  were  exercised  as  of  February  1,  2019.  The  Company  issued  37,175  ordinary  shares  at  $34.25  following  the
exercise of all Hercules warrants and receipt of $0.5 million from Hercules. During the years ended December 31, 2021
and 2020, respectively, the Company recognized no more gains or losses in Other non-operating (losses) / gains related to
fair value changes of the Hercules warrants (December 31, 2019: $0.2 million loss).

Contingent consideration

Corlieve transaction

The  Company  is  required  to  pay  up  to  EUR  178.8  million  ($202.8  million  at  the  December  31,  2021  foreign
exchange  rate)  to  the  former  shareholders  of  Corlieve  upon  the  achievement  of  contractually  defined  milestones  in
connection with the Company’s acquisition of Corlieve (refer to Note 3 “Corlieve transaction”). The Company recorded a
liability for the fair market value of the contingent consideration of EUR 20.2 million ($24.0 million) at the Acquisition
Date.  The  fair  market  value  was  determined  using  unobservable  initial  inputs  with  respect  to  (i)  the  probability  of
achieving the relevant milestones, or POS, (ii) the estimated timing of achieving such milestones, and (iii) the interest rate
used  to  discount  the  payments.  The  Company  determined  the  fair  market  value  of  the  contingent  consideration  by
calculating  the  probability-adjusted  payments  based  on  each  milestone’s  probability  of  achievement.  The  probability-
adjusted payments were then discounted to present value using a discount rate representing the Company’s credit risk. This
discount rate was determined using the effective interest rate of the Company’s existing debt facility adjusted for difference
in maturity dates based on CCC yield curve.

The fair value of the contingent consideration as of December 31, 2021 was $29.5 million using discount rates
ranging from 10.9% to 11.9% as well as a 55% likelihood of AMT-260 advancing into clinical development by no later
than  early  2024.  The  Company  increased  the  likelihood  of  advancing  into  clinical  development  from  40%  to  55%
following  the  designation  of  a  lead  candidate  in  late  October  2021,  which  resulted  in  EUR  5.0  million  ($5.8  million)
increase of the contingent liability. If as of December 31, 2021 the Company had assumed a 100% likelihood of AMT-260
advancing  into  clinical  development,  then  the  fair  value  of  the  contingent  consideration  would  have  increased  to  $47.0
million.  If  as  of  December  31,  2021  the  Company  assumed  that  it  would  discontinue  development  of  the  AMT-260
program, then the contingent consideration would be released to income. Changes in fair value of the contingent liability
are recognized within research and development expenses in the consolidated statements of operations.

The Company’s most significant leases relate to office and laboratory space under the following operating lease

agreements:

Lexington, Massachusetts / United States

In July 2013, the Company entered into a lease for a facility in Lexington, Massachusetts, United States. The term
of the lease commenced in November 2013, was set for 10 years starting from the 2014 rent commencement date and is
non-cancellable.  Originally,  the  lease  for  this  facility  had  a  termination  date  of  2024.  In  November  2018,  the  term  was
expanded  by  five  years  to  June  2029.  The  lease  continues  to  be  renewable  for  two  subsequent  five-year  terms.
Additionally, the lease was expanded to include an additional 30,655 square feet within the same facility and for the same
term. The lease of the expansion space commenced on June 1, 2019.

The  contractually  fixed  annual  increase  of  lease  payments  through  2029  for  both  the  extension  and  expansion

lease have been included in the lease payments.

In December 2021, the Company entered into a new lease for an additional facility in Lexington, Massachusetts,
United States of approximately 13,501 square feet of space. The lease is expected to commence in the second half of 2022,
is  set  for  seven  years  starting  from  the  rent  commencement  date  and  is  non-cancellable.  The  lease  is  renewable  for  one
five-year term.

Amsterdam / The Netherlands

In  March  2016,  the  Company  entered  into  a  16-year  lease  for  a  facility  in  Amsterdam,  the  Netherlands  and
amended this agreement in June 2016. The lease for the facility terminates in 2032, with an option to extend in increments
of five-year periods. The lease contract includes variable lease payments related to annual increases in payments based on a
consumer price index.

On  December  1,  2017,  the  Company  entered  into  an  agreement  to  sub-lease  three  of  the  seven  floors  of  its
Amsterdam  facility  for  a  ten-year  term  ending  on  December  31,  2027,  with  an  option  for  the  sub-lessee  to  extend  until
December  31,  2031.  In  February  2020,  the  Company  amended  the  agreement  to  sub-lease  to  take  back  one  of  the  three
floors effective March 1, 2020. The fixed lease payments to be received during the remaining term under the agreement to
sub-lease amount to $5.4 million (EUR 4.7 million) as of December 31, 2021.

In  May  2021,  the  Company  entered  into  a  sublease  agreement  to  let  an  additional  approximately  1,080  square
meters of office space to accommodate the hiring of additional full-time employees. The lease expires in October 2028 and
includes an option to break the lease on October 31, 2023.

10.           Long-term debt

On  June  14,  2013,  the  Company  entered  into  a  venture  debt  loan  facility  with  Hercules  Capital,  Inc.  (formerly
known as Hercules Technology Growth Capital, Inc.) (“Hercules”), which was amended and restated on June 26, 2014, and
again on May 6, 2016 (“2016 Amended Facility”). On December 6, 2018, the Company signed an amendment that both
refinanced the then-existing $20.0 million 2016 Amended Facility and allowed the Company to draw down an additional
$15.0 million (“2018 Amended Facility”). The 2018 Amended Facility extended the loan’s maturity date from May 1, 2020
until  June  1,  2023. The  interest  rate  is  adjustable  and  is  the  greater  of  (i)  8.85%  and  (ii)  8.85%  plus  the  prime  rate  less
5.50% per annum. Under the 2018 Amended Facility, the Company owes a back-end fee of 4.95% of the outstanding debt.
In addition, in May 2020 the Company paid a back-end fee of $1.0 million in relation to the 2016 Amended Facility.

Table of Contents

On  January  29,  2021,  the  Company  and  Hercules  amended  the  2018  Amended  Facility  (“2021  Amended
Facility”). Pursuant to the 2021 Amended Facility, Hercules agreed to an additional Facility of $100.0 million (“Tranche
B”) increasing the aggregate principal amount of the term loan facilities from $35.0 million to up to $135.0 million. On
January 29, 2021, the Company drew down $35.0 million of the Tranche B. Advances under Tranche B bore interest at a
rate  equal  to  the  greater  of  (i)  8.25%  or  (ii)  8.25%  plus  the  prime  rate,  less  3.25%  per  annum.  The  principal  balance  of
$70.0 million and all accrued but unpaid interest on advances under Tranche B was due on June 1, 2023, which date could
had been extended by the Company by up to two twelve-month periods. Advances under the 2021 Amended Facility could
have been prepaid without charge after July 29, 2021. The back-end fee in respect of advances under the 2021 Amended
Facility  ranged  from  1.65%  to  6.85%,  depending  on  the  repayment  date.  In  addition  to  Tranche  B,  the  2021  Amended
Facility had also extended the interest only payment period of the previously funded $35.0 million term loan (“Tranche A”)
from January 1, 2022 to June l, 2023.

On  December  15,  2021,  the  Company  and  Hercules  amended  and  restated  the  2021  Amended  Facility  (“2021
Restated Facility”). Pursuant to the 2021 Restated Facility, Tranche A and Tranche B of the 2021 Amended Facility  with a
total outstanding balance of $70.0 million were consolidated into one tranche with a total commitment of $100.0 million.
The Company drew down an additional $30.0 million, resulting in total principal outstanding as of December 31, 2021 of
$100.0 million. The 2021 Restated Facility extended the loan’s maturity date from June 1, 2023 until December 1, 2025.
The interest-only period is extended from January 1, 2023 to December 1, 2024, or December 1, 2025 if, prior to June 30,
2024,  either  (a)  the  BLA  for  AMT-061  is  approved  by  the  FDA  or  (b)  AMT-130  is  advanced  into  a  pivotal  trial.  The
interest rate is adjustable and is the greater of (i) 7.95% and (ii) 7.95% plus the prime rate less 3.25% per annum. Under the
2021 Restated Facility, the Company owes a back-end fee of 4.85% of the outstanding debt. The Company is required to
repay the facility in equal monthly installments of principal and interest between the end of the interest-only period and the
maturity date. The Company continues to owe a $2.5 million back-end fee related to the 2021 Amended Facility which is
due on June 1, 2023.

The amortized cost (including interest due presented as part of accrued expenses and other current liabilities) of
the 2021 Amended Facility was $101.6 million as of December 31, 2021, compared to an amortized cost of $35.9 million
for  the  2018  Amended  Facility  as  of  December  31,  2020,  and  is  recorded  net  of  discount  and  debt  issuance  costs.  The
foreign currency loss on the loan was $5.3 million in 2021 (2020: gain of $3.1 million; 2019: loss of $0.7 million). The fair
value of the loan approximates its carrying amount. Inputs to the fair value of the loan are considered Level 3 inputs.

As a covenant in the 2021 Restated Facility the Company has periodic reporting requirements and is required to
keep a minimum cash balance deposited in bank accounts in the United States, equivalent to the lesser of (i) 65% of the
outstanding balance of principal due or (ii) 100% of worldwide cash and cash equivalents. This restriction on cash and cash
equivalents only relates to the location of the cash and cash equivalents, and such cash and cash equivalents can be used at
the  discretion  of  the  Company.  The  Company,  beginning  on  April  1,  2023,  is  also  required  to  keep  a  minimum  of
unrestricted cash of at least 50% of the loan amount outstanding. If, prior to June 30, 2024, either (a) the BLA for AMT-
061 is approved by the FDA or (b) AMT-130 is advanced into a pivotal trial, the minimum cash covenant will be lowered
to at least 30% of the loan amount outstanding and its effectiveness will be deferred to April 1, 2024. In combination with
other  covenants,  the  2021  Restated  Facility  restricts  the  Company’s  ability  to,  among  other  things,  incur  future
indebtedness  and  obtain  additional  debt  financing,  to  make  investments  in  securities  or  in  other  companies,  to  transfer
assets,  to  perform  certain  corporate  changes,  to  make  loans  to  employees,  officers,  and  directors,  and  to  make  dividend
payments and other distributions to its shareholders. The Company secured the facilities by directly or indirectly pledging
its total assets of $809.2 million with the exception of $103.2 million of cash and cash equivalents and other current assets
held by uniQure N.V.

The 2021 Restated Facility contain provisions that include the occurrence of a material adverse effect, as defined
therein,  which  would  entitle  Hercules  to  declare  all  principal,  interest  and  other  amounts  owed  by  the  Company
immediately due and payable. As of December 31, 2021, the Company was in material compliance with all covenants and
provisions.

11.          Shareholders’ equity

As of December 31, 2021, the Company’s authorized share capital is €4.0 million (or $4.5 million when translated
at  an  exchange  rate  as  of  December  31,  2021,  of  $1.13  /  €1.00),  divided  into  80,000,000  ordinary  shares,  each  with  a
nominal value of €0.05. The Company’s shareholders, at the 2021 Annual General Meeting of Stockholders held on June
16, 2021, approved an increase in the number of authorized ordinary shares by 20,000,000 to 80,000,000 million.

All ordinary shares issued by the Company were fully paid. Besides the minimum amount of share capital to be

held under Dutch law, there are no distribution restrictions applicable to the equity of the Company.

As  of  December  31,  2021,  and  2020  and  2019  the  Company’s  other  comprehensive  result  was  restricted  for
payment  of  dividends  for  an  accumulated  other  comprehensive  loss  of  $28.9  million  in  2021,  an  accumulated  other
comprehensive gain of $9.9 million in 2020, and an accumulated other comprehensive loss of $6.7 million in 2019.

On March 1, 2021, the Company entered into a Sales Agreement with SVB Leerink LLC (“SVB Leerink”) with
respect  to  an  at-the-market  (“ATM”)  offering  program,  under  which  the  Company  may,  from  time  to  time  in  its  sole
discretion,  offer  and  sell  through  SVB  Leerink,  acting  as  agent,  its  ordinary  shares,  up  to  an  aggregate  offering  price  of
$200.0 million. The Company will pay SVB Leerink a commission equal to 3% of the gross proceeds of the sales price of
all ordinary shares sold through it as sales agent under the Sales Agreement. In March and April 2021, the Company issued
an  aggregate  of  921,730  ordinary  shares  at  a  weighted  average  price  of  $33.52  per  ordinary  share,  with  net  proceeds  of
$29.6  million,  after  deducting  underwriting  discounts  and  net  of  offering  expenses.  The  Company  defers  direct,
incremental  costs  associated  to  this  offering,  except  for  the  commission  costs  to  SVB  Leerink,  which  are  a  reduction  to
additional  paid-in  capital,  and  will  deduct  these  costs  from  additional  paid-in  capital  in  the  consolidated  balance  sheets
proportionately  to  the  amount  of  proceeds  raised.  During  the  year  ended  December  31,  2021,  $1.3  million  of  direct,
incremental costs were deducted from additional paid-in capital.

Following  the  Closing  of  the  CSL  Behring  transaction,  the  Company  consumed  its  tax  net  operating  loss
carryforwards  from  the  years  2011  to  2018.  The  Company  allocated  the  tax  benefit  from  the  release  of  the  valuation
allowance related to net operating loss carryforwards generated by share issuance costs incurred in 2014, 2015, 2017 and
2018 to additional paid-in capital. This resulted in an increase of additional paid-in capital of $3.0 million in the year ended
December 31, 2021.

On  September  10,  2019,  the  Company  completed  a  follow-on  public  offering  of  4,891,305  ordinary  shares  at  a
public  offering  price  of  $46.00  per  ordinary  share,  and  on  September  13,  2019,  the  Company  completed  the  sale  of  an
additional 733,695 ordinary shares at a public offering price of $46.00 per ordinary share pursuant to the exercise by the
underwriters  of  the  option  to  purchase  additional  ordinary  shares,  resulting  in  total  gross  proceeds  to  the  Company  of
$258.8  million.  The  net  proceeds  to  the  Company  from  this  offering  were  $242.7  million,  after  deducting  underwriting
discounts and commissions and other offering expenses payable by the Company. The Company deducted $0.6 million of
expenses incurred related to this offering from additional paid-in capital in the accompanying consolidated balance sheets
and  reflected  this  within  the  proceeds  from  public  offering  of  shares,  net  of  issuance  costs  within  the  cash  flows  from
financing activities.

In February 2019, the Company issued 37,175 ordinary shares to Hercules pursuant to exercised warrants for $0.5
million  in  aggregate  cash  consideration.  The  Company  deemed  the  sale  and  issuance  of  these  shares  to  be  exempt  from
registration under the Securities Act in reliance on Regulation S of the Securities Act, as an offshore offering of securities
and  such  shares  were  issued  as  restricted  shares.  Hercules  represented  to  us  that  they  were  in  compliance  with  the
requirements of Regulation S.

The  Company  satisfies  the  exercise  of  share  options  and  vesting  of  Restricted  Share  Units  (“RSUs”)  and

Performance Share Units (“PSUs”) through newly issued shares.

The Company’s share-based compensation plans include the 2014 Amended and Restated Share Option Plan (the
“2014 Plan”) and inducement grants under Rule 5653(c)(4) of The Nasdaq Global Select Market with terms similar to the
2014 Plan (together the “2014 Plans”). The Company previously had a 2012 Equity Incentive Plan (the “2012 Plan”). As of

The  Company  granted  shares  to  certain  employees  in  September  and  December  2021  that  will  be  earned  upon
achievement of defined milestones. Earned shares will vest upon the later of a minimum service period of one year or three
years, or the achievement of defined milestones, subject to the grantee’s continued employment. In addition, portions of the
December 2021 granted to executives and other members of senior management are subject to achieving a minimum total
shareholder return relative to the Nasdaq biotechnology index. The Company recognizes the compensation cost related to
these grants to the extent it considers achievement of the milestones to be probable.

In January 2018 and January and February 2019, the Company awarded PSUs to its executives and other members
of senior management. These PSUs were earned in January 2019 and January 2020, based on the Board’s assessment of the
level  of  achievement  of  agreed  upon  performance  targets  through  December  31,  2018,  and  December  31,  2019,
respectively. The PSUs awarded for the year ended December 31, 2018 vested in February 2021 and the PSUs awarded for

identifiable intangible assets and a deferred tax asset for net operating tax loss carryforwards for a net of EUR 11.9 million
($14.2 million) as of the Acquisition Date.

There are no significant unrecognized tax benefits as of December 31, 2021 and 2020.

The Company released the full valuation allowance against the Company’s net deferred assets in the United States
as of December 31, 2020. Included within changes recorded in the statement of operations for the year ended December 31,
2020 and December 31, 2019 are benefits of $1.2 million and $0.8 million, respectively, from the utilization of U.S. net
operating loss carryforwards.

The valuation allowance as of December 31, 2021 is primarily related to net operating loss carryforwards in the
Netherlands  that,  in  the  judgment  of  management,  are  not  more-likely  than-not  to  be  realized.  Management  considered
reversing  taxable  temporary  differences,  projected  future  taxable  income  and  tax-planning  strategies  in  making  this
assessment. A valuation allowance was recorded against deferred tax assets if it is more likely than not that some or all the
deferred tax assets will not be realized.

Netherlands

As of December 31, 2020, the Company had recorded a full valuation allowance against its Dutch net deferred tax
assets. On May 6, 2021, the CSL Behring Agreement became effective (refer to Note 4 “Collaboration arrangements and
concentration of credit risk”). The Company recorded $462.4 million of license revenue related to closing the transaction.
The  Company  recorded  such  revenue  in  its  Dutch  tax  return  related  to  the  12-month  period  ended  December  31,  2020,
which it filed on February 10, 2022. As such, the Company filed a return showing a taxable profit in the Netherlands in
2020, which resulted in the consumption of substantially all of its Dutch net operating losses for the years 2011 to 2018.
The Company’s remaining Dutch net operating tax losses carried forward relate to 2019 and 2021. The Dutch government
on  June  4,  2021  enacted  legislation,  whereby  such  net  operating  tax  losses  can  be  carried  forward  indefinitely.  The
Company expects to continue incurring tax losses for the foreseeable future. As such, the Company retains its valuation
allowance related to the deferred assets as of December 31, 2021. The Company allocated the tax benefit from the release
of the valuation allowance related to net operating loss carryforwards generated by share issuance cost incurred in 2014,
2015,  2017  and  2018  to  additional  paid-in  capital.  This  resulted  in  an  increase  of  additional  paid-in  capital  as  well  as
deferred tax expenses of $3.0 million.

A portion of the valuation allowance for deferred tax assets relates to follow-on offering costs incurred in 2019
and costs related to the at-the-market offering in 2021. Any subsequently recognized tax benefits will be credited directly
to contributed capital. As of December 31, 2021, that amount was $4.5 million ($7.7 million as of December 31, 2020).

The Dutch corporate tax rate for fiscal years 2019, 2020 and 2021 was 25%. During 2019, the Dutch government
enacted  various  changes  to  the  corporate  income  tax  rate  applicable  to  future  fiscal  years.  In  September  2020,  further
changes were enacted that retain the corporate income tax rate at 25% from 2021 onwards. In December 2021, even further
changes were enacted that raised the corporate income tax rate from 25% to 25.8% from 2022 onwards.

A tax reform in December 2018 limited the carryforward of tax losses arising from January 1, 2019, to six years
after the end of the respective period. Tax losses incurred prior to this date continue to expire nine years after the end of the
respective period.

In  June  2021  legislation  was  enacted  allowing  for  an  indefinite  carryforward  from  fiscal  year  2022  onwards  of
existing  and  future  net  operating  loss  carryforwards  subject  to  a  limit  of  offsetting  taxable  profit  in  excess  of  EUR  1.0
million to 50% of the taxable profit.

The  Dutch  fiscal  unity  as  of  December  31,  2021  has  an  estimated  $228.5  million  (2020:  $588.2  million;  2019:
$414.0 million) of taxable losses that are available for carry forward indefinitely. In the year ended December 31, 2019,
unused tax losses of $20.7 million expired.

The fiscal periods from 2019 onwards are still open for inspection by the Dutch tax authorities.

United States of America

The  federal  corporate  tax  rate  in  the  U.S.  is  21%.  In  addition,  the  Company  is  subject  to  state  income  taxes
resulting in a combined tax rate of 27.32% for its U.S. operation. As of December 31, 2021, an estimated $39.1 million of
net operating losses remain to be carried forward. These losses will expire between 2035 and 2037.

The Company’s U.S. operations generated taxable income in the fiscal years 2018 to 2021. Based on the current
design of the Company’s worldwide operations, the Company expects to continue to generate taxable income in the U.S.
during the foreseeable future.

Under the provision of the Internal Revenue Code, the U.S. net operating losses may become subject to an annual
limitation in the event of certain cumulative exchange in the ownership interest of significant shareholders over a three-
year period in excess of 50 percent, as defined under Section 382 and 383 of the Internal Revenue Code. This could limit
the amount of tax attributes that can be utilized annually to offset future taxable income or tax liabilities. The amount of the
annual limitation is determined based on the value of the Company immediately prior to the ownership change. Subsequent
ownership changes may further affect the limitation.

The fiscal periods from 2018 are still open for inspection by the Internal Revenue Service (“IRS”). To the extent
the Company has tax attribute carryforwards, the tax years in which the attribute was generated may still be adjusted upon
examination by the IRS or Massachusetts Department of Revenue to the extent utilized in a future period. The Company is
currently not under examination by the IRS for any tax years.

France

The French corporate tax rate for fiscal years 2021 was 26.5%, as of January 1, 2022 the tax rate is decreased to

25%. 

The Company’s French operation has incurred losses since incorporation and is expected to continue incurring tax

losses for the foreseeable future.

The French operation as of December 31, 2021 has an estimated $9.1 million of taxable losses that are available

for carry forward indefinitely.

16.          Basic and diluted earnings per share

Basic  net  income  /  (loss)  per  ordinary  share  is  computed  by  dividing  net  income  /  (loss)  for  the  period  by  the
weighted  average  number  of  ordinary  shares  outstanding  during  the  period.  Diluted  earnings  per  ordinary  share  are
calculated by adjusting the weighted average number of ordinary shares outstanding, assuming conversion of all potentially
dilutive ordinary shares. For the year ended December 31, 2021, dilutive net income / (loss) per ordinary share is computed
using the treasury method. As the Company has incurred a loss in the years ended December 31, 2020 and December 31,
2019, all potentially dilutive ordinary shares for these years would have an antidilutive effect, if converted, and thus have
been excluded from the computation of loss per share for the years ended December 31, 2020 and December 31, 2019.

The  following  table  presents  ordinary  share  equivalents  that  were  excluded  from  the  calculation  of  diluted  net
income / (loss) per ordinary share for the years ended December 31, 2021, 2020 and 2019 as the effect of their inclusion
would have been anti-dilutive:

The anti-dilutive ordinary shares are presented without giving effect to the application of the treasury method or
exercise prices that exceeded the price of the Company’s ordinary shares as of December 31, 2020 and December 31, 2019.
In  addition,  the  BMS  warrants  were  not  exercisable  as  of  December  31,  2019,  since  this  would  have  required  the  prior
designation of Collaboration Targets by BMS. This would have resulted in a lower number of potentially dilutive ordinary
shares as some stock option grants as well as the BMS warrants would have been excluded.

17.          Commitments and contingencies

In  the  course  of  its  business,  the  Company  enters  as  a  licensee  into  contracts  with  other  parties  regarding  the
development and marketing of its pipeline products. Among other payment obligations, the Company is obligated to pay
royalties to the licensors based on future sales levels and milestone payments whenever specified development, regulatory
and  commercial  milestones  are  met.  As  both  future  sales  levels  and  the  timing  and  achievement  of  milestones  are
uncertain, the financial effect of these agreements cannot be estimated reliably. The Company also has obligations to make
future  payments  that  become  due  and  payable  upon  the  collection  of  milestone  payments  from  CSL  Behring.  The
achievement and timing of these milestones is not fixed and determinable. Relevant commitments and contingencies are
further discussed in other sections of this form 10-K, such as, Note 3 “Corlieve transaction” and Note 4 “Collaboration
arrangements and concentration of credit risk”, amongst others.

18.        Related party transaction

Between June 2015 and December 2020, BMS was considered a related party due to the combination of its equity
investment in the Company, the warrants as well as the potential obligations arising from the expansion of collaboration
targets.  On  December  1,  2020,  the  Company  entered  into  the  amended  BMS  CLA.  All  transactions  subsequent  to  the
effective date of the amended BMS CLA are considered to no longer be with a related party due to the elimination of the
potential  obligations  related  to  additional  Collaboration  Targets  (see  Note  4  “Collaboration  arrangements  and
concentration of credit risk”) as well as the elimination of the BMS warrants (see Note 5, “Fair value measurement”).

DESCRIPTION OF THE REGISTRANT’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF THE
SECURITIES EXCHANGE ACT OF 1934

The following description sets forth certain material terms and provisions of uniQure N.V.’s (“uniQure N.V.”,
“we,”  “us,”  and  “our”)  securities  that  are  registered  under  Section  12  of  the  Securities  Exchange  Act  of  1934,  as
amended. The description below of our ordinary shares and provisions of our articles of association are summaries and
are qualified by reference to our articles of association and the applicable provisions of Dutch law.

DESCRIPTION OF CAPITAL STOCK

The following description of the general terms and provisions of our ordinary shares is a summary only and
therefore is not complete and is subject to, and qualified in its entirety by reference to, the terms and provisions of our
articles of association. Our articles of association have been filed with the SEC as an exhibit to the Annual Report on
Form 10-K of which this Exhibit 4.1 is a part and you should read the articles for provisions that may be important to
you.

Authorized Ordinary Shares

        Our articles of association provide an authorized share capital of 80,000,000 ordinary shares, each with a nominal
value per share of €0.05.

Form of Ordinary Shares

        We issue our ordinary shares in registered book-entry form and such shares are not certificated.

NASDAQ Global Market Listing

        Our ordinary shares are listed on The NASDAQ Global Market under the symbol "QURE."

Comparison of Dutch corporate law and our Articles of Association and Delaware corporate law

        The following comparison between Dutch corporate law, which applies to us, and Delaware corporate law, the
law under which many publicly listed companies in the United States are incorporated, discusses additional matters not
otherwise described in this exhibit. This summary is subject to Dutch law, including Book 2 of the Dutch Civil Code
and Delaware corporation law, including the Delaware General Corporation Law.

Corporate governance

Duties of directors

        The Netherlands.    We have a one tier board structure consisting of our executive directors and non-executive
directors.  Under  the  one-tier  board  structure,  both  the  executive  and  non-executive  directors  will  be  collectively
responsible for the management performed by the one-tier board and for the general policy and strategy of a company.
The executive directors are responsible for the day-to-day management of a company. The non-executive directors are
responsible  for  supervising  the  conduct  of,  and  providing  advice  to,  the  executive  directors  and  for  providing
supervision with respect to the company's general state of affairs. Each executive director and non-executive director
has  a  duty  to  act  in  the  corporate  interest  of  the  company.  Under  Dutch  law,  the  corporate  interest  extends  to  the
interests of all corporate stakeholders, such as shareholders, creditors, employees, customers and suppliers. The duty to
act  in  the  corporate  interest  of  the  company  also  applies  in  the  event  of  a  proposed  sale  or  split-up  of  a  company,
whereby the circumstances generally dictate how such duty is to be applied. Any resolution of the board regarding a
significant change in the identity or character of a company requires shareholders' approval.

 
        Delaware.    The board of directors bears the ultimate responsibility for managing the business and affairs of a
corporation. In discharging this function, directors of a Delaware corporation owe fiduciary duties of care and loyalty
to the corporation and to its stockholders. Delaware courts have decided that the directors of a Delaware corporation
are required to exercise informed business judgment in the performance of their duties. Informed business judgment
means that the directors have informed themselves of all material information reasonably available to them. Delaware
courts  have  also  imposed  a  heightened  standard  of  conduct  upon  directors  of  a  Delaware  corporation  who  take  any
action designed to defeat a threatened change in control of the corporation. In addition, under Delaware law, when the
board of directors of a Delaware corporation approves the sale or break-up of a corporation, the board of directors may,
in certain circumstances, have a duty to obtain the highest value reasonably available to the stockholders.

Director terms

        The Netherlands.    Under Dutch law, executive directors of a listed company are generally appointed for a term
of a maximum of four years and reappointed for a term of a maximum of four years at a time. Non-executive directors
of a listed company are generally appointed for a term of a maximum of four years and reappointed once for another
term of a maximum of four years. Non-executive directors of a listed company subsequently are typically reappointed
for a term of a maximum of two years, which reappointment may be extended by two years. Our executive and non-
executive directors are, in principle, appointed by the general meeting of shareholders upon the binding nomination of
the non-executive directors.

        The general meeting of shareholders is entitled at all times to suspend or dismiss a director. The general meeting
of shareholders may only adopt a resolution to suspend or dismiss such director by at least a two-thirds majority of the
votes cast, if such majority represents more than half of the issued share capital of the company.

        Delaware.    The Delaware General Corporation Law generally provides for a one-year term for directors, but
permits directorships to be divided into up to three classes with up to three-year terms, with the years for each class
expiring in different years, if permitted by a company's certificate of incorporation, an initial bylaw or a bylaw adopted
by the stockholders. A director elected to serve a term on such a classified board may not be removed by stockholders
without cause. There is no limit in the number of terms a director may serve.

Director vacancies

        The Netherlands.    Under Dutch law, directors are appointed by the general meeting of shareholders. Under our
articles of association, directors are, in principle, appointed by the general meeting of shareholders upon the binding
nomination  by  the  non-executive  directors.  However,  the  general  meeting  of  shareholders  may  at  all  times  overrule
such  binding  nomination  by  a  resolution  adopted  by  at  least  a  two-thirds  majority  of  the  votes  cast,  provided  such
majority represents more than half of the issued share capital of our company. If the general meeting of shareholders
overrules the binding nomination, the non-executive directors must make a new nomination.

        Delaware.    The Delaware General Corporation Law provides that vacancies and newly created directorships
may  be  filled  by  a  majority  of  the  directors  then  in  office  (even  though  less  than  a  quorum)  unless  (1)  otherwise
provided in the certificate of incorporation or bylaws of the corporation or (2) the certificate of incorporation directs
that a particular class of stock is to elect such director, in which case any other directors elected by such class, or a sole
remaining director elected by such class, will fill such vacancy.

Conflict-of-interest transactions

        The Netherlands.    Pursuant to Dutch law and our articles of association, directors may not take part in any
discussion or decision-making that involves a subject or transaction in relation to which they have a personal direct or
indirect conflict of interest with us. Our articles of association provide that if as a result thereof, the board is unable to
act the resolution will be adopted by the general meeting of shareholders.

                Delaware.        The  Delaware  General  Corporation  Law  generally  permits  transactions  involving  a  Delaware
corporation and an interested director of that corporation if:

● the  material  facts  as  to  the  director's  relationship  or  interest  are  disclosed  and  a  majority  of  disinterested

directors consent;

● the material facts are disclosed as to the director's relationship or interest and a majority of shares entitled to

vote thereon consent; or

● the transaction is fair to the corporation at the time it is authorized by the board of directors, a committee of

the board of directors or the stockholders.

Shareholder rights

Voting rights

        The Netherlands.        In  accordance  with  Dutch  law  and  our  articles  of  association,  each  issued  ordinary  share
confers the right to cast one vote at the general meeting of shareholders. Each holder of ordinary shares may cast as
many votes as it holds shares. Shares that are held by us or our direct or indirect subsidiaries do not confer the right to
vote. Dutch law does not permit cumulative voting for the election of executive directors and non-executive directors.

        For each general meeting of shareholders, a record date will be applied with respect to ordinary shares in order to
establish which shareholders are entitled to attend and vote at a specific general meeting of shareholders. Such record
date is set by the board. The record date and the manner in which shareholders can register and exercise their rights
will be set out in the convocation notice of the meeting.

        Delaware.    Under the Delaware General Corporation Law, each stockholder is entitled to one vote per share of
stock,  unless  the  certificate  of  incorporation  provides  otherwise.  In  addition,  the  certificate  of  incorporation  may
provide  for  cumulative  voting  at  all  elections  of  directors  of  the  corporation,  or  at  elections  held  under  specified
circumstances.  Either  the  certificate  of  incorporation  or  the  bylaws  may  specify  the  number  of  shares  and/or  the
amount of other securities that must be represented at a meeting in order to constitute a quorum, but in no event will a
quorum consist of less than one third of the shares entitled to vote at a meeting.

        Stockholders as of the record date for the meeting are entitled to vote at the meeting, and the board of directors
may fix a record date that is no more than 60 nor less than ten days before the date of the meeting, and if no record
date is set then the record date is the close of business on the day next preceding the day on which notice is given, or if
notice is waived then the record date is the close of business on the day next preceding the day on which the meeting is
held. The determination of the stockholders of record entitled to notice or to vote at a meeting of stockholders shall
apply  to  any  adjournment  of  the  meeting,  but  the  board  of  directors  may  fix  a  new  record  date  for  the  adjourned
meeting.

Shareholder proposals

        The Netherlands.    Pursuant to our articles of association, extraordinary general meetings of shareholders will be
convened  by  the  board  or  by  those  who  are  authorized  by  law  or  pursuant  to  our  articles  of  association  to  do  so.
Pursuant  to  Dutch  law,  one  or  more  shareholders  representing  at  least  one-tenth  of  the  issued  share  capital  of  the
company may request the Dutch courts to order that they be authorized by the court to convene a general meeting of
shareholders. The court shall disallow the request if it does not appear that the applicants have previously requested the
board  to  convene  a  general  meeting  of  shareholders  and  the  board  has  taken  the  necessary  steps  so  that  the  general
meeting of shareholders could be held within six weeks after the request.

        The agenda for a general meeting of shareholders must include such items requested by one or more shareholders
representing at least 3% of the issued share capital of a company or such lower percentage as the articles of association
may provide. Our articles of association do not state such lower percentage.

        Delaware.    Delaware law does not specifically grant stockholders the right to bring business before an annual or
special meeting. However, if a Delaware corporation is subject to the SEC's proxy rules, a stockholder who owns

at least $2,000 in market value, or 1% of the corporation's securities entitled to vote, may propose a matter for a vote at
an annual or special meeting in accordance with those rules.

Action by written consent

        The Netherlands.    Under Dutch law, the articles of association of a company may provide that shareholders'
resolutions may be adopted in writing without holding a general meeting of shareholders, provided that the resolution
is  adopted  unanimously  by  all  shareholders  that  are  entitled  to  vote.  For  a  listed  company,  this  method  of  adopting
resolutions is not feasible.

        Delaware.    Although permitted by Delaware law, publicly listed companies do not typically permit stockholders
of a corporation to take action by written consent.

Appraisal rights

        The Netherlands.    The concept of appraisal rights does not exist under Dutch law. However, pursuant to Dutch
law a shareholder who for its own account contributes at least 95% of our issued share capital may initiate proceedings
against  our  minority  shareholders  jointly  for  the  transfer  of  their  shares  to  it.  The  proceedings  are  held  before  the
Enterprise Chamber (Ondernemingskamer). The Enterprise Chamber may grant the claim for squeeze-out in relation to
all minority shareholders and will determine the price to be paid for the shares, if necessary after appointment of one or
three experts who will offer an opinion to the Enterprise Chamber on the value to be paid for the shares of the minority
shareholders.

                Furthermore,  in  accordance  with  Directive  2005/56/EC  of  the  European  Parliament  and  the  Council  of
October  26,  2005  on  cross-border  mergers  of  limited  liability  companies,  Dutch  law  provides  that,  to  the  extent  the
acquiring company in a cross-border merger is organized under the laws of another EU member state, a shareholder of
a  Dutch  disappearing  company  who  has  voted  against  the  cross-border  merger  may  file  a  claim  with  the  Dutch
company for compensation. The compensation is to be determined by one or more independent experts.

        Delaware.    The Delaware General Corporation Law provides for stockholder appraisal rights, or the right to
demand payment in cash of the judicially determined fair value of the stockholder's shares, in connection with certain
mergers and consolidations.

Shareholder suits

        The Netherlands.    In the event a third party is liable to a Dutch company, only a company itself can bring a civil
action  against  that  third  party.  An  individual  shareholder  does  not  have  the  right  to  bring  an  action  on  behalf  of  a
company. This individual shareholder may, in its own name, have an individual right to take action against such third
party in the event that the cause for the liability of that third party also constitutes a tortious act directly against that
individual  shareholder.  The  Dutch  Civil  Code  provides  for  the  possibility  to  initiate  such  action  collectively.  A
collective action can be instituted by a foundation or an association whose objective is to protect the rights of a group
of  persons  having  similar  interests.  The  collective  action  itself  cannot  result  in  an  order  for  payment  of  monetary
damages but may only result in a declaratory judgment (verklaring voor recht). In order to obtain compensation for
damages, the foundation or association and the defendant may reach—often on the basis of such declaratory judgment
—a settlement. A Dutch court may declare the settlement agreement binding upon all the injured parties with an opt-
out choice for an individual injured party. An individual injured party may also itself—outside the collective action—
institute a civil claim for damages.

        Delaware.    Under the Delaware General Corporation Law, a stockholder may bring a derivative action on behalf
of the corporation to enforce the rights of the corporation. An individual also may commence a class action suit on
behalf of himself and other similarly situated stockholders where the requirements for maintaining a class action under
Delaware law have been met. A person may institute and maintain such a suit only if that person was a stockholder at
the time of the transaction which is the subject of the suit. In addition, under Delaware case law, the plaintiff normally
must be a stockholder at the time of the transaction that is the subject of the suit and throughout the duration of the
derivative  suit.  Delaware  law  also  requires  that  the  derivative  plaintiff  make  a  demand  on  the  directors  of  the
corporation to assert the corporate claim before the suit may be prosecuted by the derivative plaintiff in court, unless
such a demand would be futile.

Repurchase of shares

        The Netherlands.    Under Dutch law, a company such as ours may not subscribe for newly issued shares in its
own  share  capital.  Such  company  may,  however,  subject  to  certain  restrictions  under  Dutch  law  and  its  articles  of
association, acquire shares in its own share capital. We may acquire fully paid-up shares in our own share capital at
any  time  for  no  valuable  consideration.  Furthermore,  subject  to  certain  provisions  of  Dutch  law  and  our  articles  of
association, we may repurchase fully paid-up shares in our own share capital if (1) such repurchase would not cause
our shareholders' equity to fall below an amount equal to the sum of the paid-up and called-up part of the issued share
capital and the reserves we are required to maintain pursuant to applicable law and (2) we would not as a result of such
repurchase hold more than 50% of our own issued share capital.

                Other  than  shares  acquired  for  no  valuable  consideration,  ordinary  shares  may  only  be  acquired  following  a
resolution of our board, acting pursuant to an authorization for the repurchase of shares granted by the general meeting
of shareholders. An authorization by the general meeting of shareholders for the repurchase of shares can be granted
for a maximum period of 18 months. Such authorization must specify the number of shares that may be acquired, the
manner in which these shares may be acquired and the price range within which the shares may be acquired. Our board
has  been  authorized,  for  a  period  of  18  months  to  be  calculated  from  the  date  of  the  annual  general  meeting  of
shareholders held on June 16, 2021, to cause the repurchase of ordinary shares by us of up to 10% of our issued share
capital, for a price per share between the nominal value of the ordinary shares and an amount of 110% of the highest
price of the ordinary shares officially quoted on any of the official stock markets we are listed on during any of 30
banking days preceding the date the repurchase is effected or proposed.

        No authorization of the general meeting of shareholders is required if fully paid-up ordinary shares are acquired
by  us  with  the  intention  of  transferring  such  ordinary  shares  to  our  employees  under  an  applicable  employee  stock
purchase plan, provided such ordinary shares are officially quoted on any of the official stock markets.

        Delaware.    Under the Delaware General Corporation Law, a corporation may purchase or redeem its own shares
unless  the  capital  of  the  corporation  is  impaired  or  the  purchase  or  redemption  would  cause  an  impairment  of  the
capital  of  the  corporation.  A  Delaware  corporation  may,  however,  purchase  or  redeem  out  of  capital  any  of  its
preferred  shares  or,  if  no  preferred  shares  are  outstanding,  any  of  its  own  shares  if  such  shares  will  be  retired  upon
acquisition and the capital of the corporation will be reduced in accordance with specified limitations.

Anti-takeover provisions

                The  Netherlands.        Under  Dutch  law,  various  protective  measures  are  possible  and  permissible  within  the
boundaries  set  by  Dutch  statutory  law  and  Dutch  case  law.  We  have  adopted  several  provisions  that  may  have  the
effect of making a takeover of our company more difficult or less attractive, including:

● the staggered four-year terms of our directors, as a result of which only approximately one-fourth of our non-

executive directors will be subject to election in any one year;

● a  provision  that  our  directors  may  only  be  removed  at  the  general  meeting  of  shareholders  by  a  two-thirds

majority of votes cast representing more than half of our issued share capital; and

● requirements that certain matters, including an amendment of our articles of association, may only be brought

to our shareholders for a vote upon a proposal by our board.

                Delaware.        In  addition  to  other  aspects  of  Delaware  law  governing  fiduciary  duties  of  directors  during  a
potential takeover, the Delaware General Corporation Law also contains a business combination statute that protects
Delaware companies from hostile takeovers and from actions following the takeover by prohibiting some transactions
once an acquirer has gained a significant holding in the corporation.

● Section 203 of the Delaware General Corporation Law prohibits "business combinations," including mergers,
sales and leases of assets, issuances of securities and similar transactions by a corporation or a subsidiary with
an  interested  stockholder  that  beneficially  owns  15%  or  more  of  a  corporation's  voting  stock,  within  three
years after the person becomes an interested stockholder, unless: the transaction that will cause the person to
become an interested stockholder is approved by the board of directors of the target prior to the transactions;

● after the completion of the transaction in which the person becomes an interested stockholder, the interested
stockholder holds at least 85% of the voting stock of the corporation not including shares owned by persons
who  are  directors  and  representatives  of  interested  stockholders  and  shares  owned  by  specified  employee
benefit plans; or

● after  the  person  becomes  an  interested  stockholder,  the  business  combination  is  approved  by  the  board  of
directors of the corporation and holders of at least 66.67% of the outstanding voting stock, excluding shares
held by the interested stockholder.

        A Delaware corporation may elect not to be governed by Section 203 by a provision contained in the original
certificate  of  incorporation  of  the  corporation  or  an  amendment  to  the  original  certificate  of  incorporation  or  to  the
bylaws of the company, which amendment must be approved by a majority of the shares entitled to vote and may not
be  further  amended  by  the  board  of  directors  of  the  corporation.  Such  an  amendment  is  not  effective  until  twelve
months following its adoption.

Inspection of books and records

                The  Netherlands.        Our  board  provides  the  shareholders,  at  the  general  meeting  of  shareholders,  with  all
information  that  the  shareholders  require  for  the  exercise  of  their  powers,  unless  doing  so  would  be  contrary  to  an
overriding interest of ours. Our board must give reason for electing not to provide such information on the basis of an
overriding interest.

                Delaware.        Under  the  Delaware  General  Corporation  Law,  any  stockholder  may  inspect  certain  of  the
corporation's books and records, for any proper purpose, during the corporation's usual hours of business.

Removal of directors

        The Netherlands.    Under our articles of association, the general meeting of shareholders is at all times entitled to
suspend or dismiss a director. The general meeting of shareholders may only adopt a resolution to suspend or dismiss
such a member by at least a two-thirds majority of the votes cast, provided such majority represents more than half of
the issued share capital of our company.

        Delaware.    Under the Delaware General Corporation Law, any director or the entire board of directors may be
removed,  with  or  without  cause,  by  the  holders  of  a  majority  of  the  shares  then  entitled  to  vote  at  an  election  of
directors, except (1) unless the certificate of incorporation provides otherwise, in the case of a corporation whose board
is  classified,  stockholders  may  effect  such  removal  only  for  cause,  or  (2)  in  the  case  of  a  corporation  having
cumulative voting, if less than the entire board is to be removed, no director may be removed without cause if the votes
cast against his removal would be sufficient to elect him if then cumulatively voted at an election of the entire board of
directors, or, if there are classes of directors, at an election of the class of directors of which he is a part.

Preemptive rights

        The Netherlands.    Under Dutch law, in the event of an issuance of ordinary shares, each shareholder will have a
pro rata preemptive right in proportion to the aggregate nominal value of the ordinary shares held by such holder (with
the exception of ordinary shares to be issued to employees or ordinary shares issued against a contribution other than
in  cash).  Under  our  articles  of  association,  the  preemptive  rights  in  respect  of  newly  issued  ordinary  shares  may  be
restricted or excluded by a resolution of the general meeting of shareholders upon proposal of our board. The general
meeting of shareholders may designate our board to restrict or exclude the preemptive rights in respect of newly issued
ordinary  shares.  Such  designation  can  be  granted  for  a  period  not  exceeding  five  years.  A  resolution  of  the  general
meeting of shareholders to restrict or exclude the preemptive rights or to designate the board as the authorized body to
do so requires a two-thirds majority of the votes cast, if less than one half of our issued share capital is represented at
the meeting.

               At  our  annual  general  meeting  of  shareholders  held  on  June  16,  2021,  the  general  meeting  of  shareholders
resolved to authorize our board for a period of 18 months with effect from the date of the meeting to restrict or exclude
preemptive  rights  accruing  to  shareholders  in  connection  with  the  issue  of  ordinary  shares  or  rights  to  subscribe  for
ordinary shares.

        Delaware.    Under the Delaware General Corporation Law, stockholders have no preemptive rights to subscribe
for additional issues of stock or to any security convertible into such stock unless, and to the extent that, such rights are
expressly provided for in the certificate of incorporation.

Dividends

        The Netherlands.    Dutch law provides that dividends may be distributed after adoption of the annual accounts by
the  general  meeting  of  shareholders  from  which  it  appears  that  such  dividend  distribution  is  allowed.  Moreover,
dividends may be distributed only to the extent that the shareholders' equity exceeds the amount of the paid-up and
called-up part of the issued share capital of the company and the reserves that must be maintained under the law or the
articles  of  association.  Interim  dividends  may  be  declared  as  provided  in  the  articles  of  association  and  may  be
distributed to the extent that the shareholders' equity exceeds the amount of the paid-up and called-up part of the issued
share capital of the company and the reserves that must be maintained under the law or the articles of association, as
apparent from an interim statement of assets and liabilities.

        Under our articles of association, any amount of profit may be carried to a reserve as our board determines. After
reservation by our board of any profit, the remaining profit will be at the disposal of the shareholders. Our corporate
policy  is  to  only  make  a  distribution  of  dividends  to  our  shareholders  after  the  adoption  of  our  annual  accounts
demonstrating that such distribution is legally permitted. However, our board is permitted to declare interim dividends
without the approval of the general meeting of shareholders.

                Dividends  will  be  made  payable  not  later  than  thirty  days  after  the  date  they  were  declared  unless  the  body
declaring the dividend determines a different date. Claims to dividends not made within five years and one day from
the date that such dividends became payable will lapse and any such amounts will be considered to have been forfeited
to us (verjaring).

        Delaware.    Under the Delaware General Corporation Law, a Delaware corporation may pay dividends out of its
surplus (the excess of net assets over capital), or in case there is no surplus, out of its net profits for the fiscal year in
which  the  dividend  is  declared  and/or  the  preceding  fiscal  year  (provided  that  the  amount  of  the  capital  of  the
corporation is not less than the aggregate amount of the capital represented by the issued and outstanding stock of all
classes  having  a  preference  upon  the  distribution  of  assets).  In  determining  the  amount  of  surplus  of  a  Delaware
corporation, the assets of the corporation, including stock of subsidiaries owned by the corporation, must be valued at
their fair market value as determined by the board of directors, without regard to their historical book value. Dividends
may be paid in the form of shares, property or cash.

Shareholder vote on certain reorganizations

        The Netherlands.    Under Dutch law, the general meeting of shareholders must approve resolutions of the board
relating to a significant change in the identity or the character of the company or the business of the company, which
includes:

● a transfer of the business or virtually the entire business to a third party;
● the  entry  into  or  termination  of  a  long-term  cooperation  of  the  company  or  a  subsidiary  with  another  legal
entity  or  company  or  as  a  fully  liable  partner  in  a  limited  partnership  or  general  partnership,  if  such
cooperation or termination is of a far-reaching significance for the company; and

● the  acquisition  or  divestment  by  the  company  or  a  subsidiary  of  a  participating  interest  in  the  capital  of  a
company having a value of at least one third of the amount of its assets according to its balance sheet and
explanatory  notes  or,  if  the  company  prepares  a  consolidated  balance  sheet,  according  to  its  consolidated
balance sheet and explanatory notes, according to the last adopted annual accounts of the company.

        Delaware.    Under the Delaware General Corporation Law, the vote of a majority of the outstanding shares of
capital stock entitled to vote thereon generally is necessary to approve a merger or consolidation or the sale of all or
substantially  all  of  the  assets  of  a  corporation.  The  Delaware  General  Corporation  Law  permits  a  corporation  to
include in its certificate of incorporation a provision requiring for any corporate action the vote of a larger portion of
the stock or of any class or series of stock than would otherwise be required.

        Under the Delaware General Corporation Law, no vote of the stockholders of a surviving corporation to a merger
is needed, however, unless required by the certificate of incorporation, if (1) the agreement of merger does not amend
in  any  respect  the  certificate  of  incorporation  of  the  surviving  corporation,  (2)  the  shares  of  stock  of  the  surviving
corporation are not changed in the merger and (3) the number of shares of common stock of the surviving corporation
into which any other shares, securities or obligations to be issued in the merger may be converted does not exceed 20%
of  the  surviving  corporation's  common  stock  outstanding  immediately  prior  to  the  effective  date  of  the  merger.  In
addition, stockholders may not be entitled to vote in certain mergers with other corporations that own 90% or more of
the  outstanding  shares  of  each  class  of  stock  of  such  corporation,  but  the  stockholders  will  be  entitled  to  appraisal
rights.

Remuneration of directors

        The Netherlands.    Under Dutch law and our articles of association, we must adopt a remuneration policy for our
directors. Such remuneration policy shall be adopted by the general meeting of shareholders upon the proposal of our
non-executive  directors.  The  remuneration  of  our  executive  directors  will  be  determined  by  our  non-executive
directors  with  due  observance  of  our  remuneration  policy;  the  remuneration  of  our  non-executive  directors  will  be
determined by the board with due observance of our remuneration policy.

        Delaware.    Under the Delaware General Corporation Law, the stockholders do not generally have the right to
approve the compensation policy for directors or the senior management of the corporation, although certain aspects of
executive compensation may be subject to binding or advisory stockholder votes due to the provisions of U.S. federal
securities and tax law, as well as stock exchange requirements.

Transfer Agent and Registrar

        Computershare Trust Company, N.A. serves as transfer agent and registrar for our ordinary shares.

uniQure N.V.

Share Option Agreement
Granted Under 2014 Share Incentive Plan,
Amended and Restated effective as of June 16, 2021 (the “Amendment Date”)

Exhibit 10.65

1.

Grant of Option.

This agreement together with the Notice of Grant evidences the grant by uniQure N.V., a public limited

company incorporated under the laws of the Netherlands (the “Company”), on the “Award Date” to the
“Participant”, of an option to purchase, in whole or in part, on the terms provided herein and in the Company’s
2014 Share Incentive Plan, as amended and restated as of the Amendment Date (the “Plan”), that number of
ordinary shares, €0.05 par value per share, of the Company (“Ordinary Shares”) at the price per share, each as
set forth in the applicable Notice of Grant. Unless earlier terminated, this option shall expire at 17:00, Central
European time, on the “Award Expiration Date” as set forth in the applicable Notice of Grant (the “Final Exercise
Date”).

2.

Vesting Schedule.

(a)

This option will become exercisable (“vest”) in the amount set forth next to the respective Vesting

Date set forth in the applicable Notice of Grant, in each case, subject to continued employment as an Eligible
Participant (as defined below in Section 3(b)).

(b)

The right of exercise shall be cumulative (but shall not exceed 100% of the Ordinary Shares
subject to the Option) so that to the extent the option is not exercised in any period to the maximum extent
permissible it shall continue to be exercisable, in whole or in part, with respect to all Ordinary Shares for which it
is vested until the earlier of the Final Exercise Date or the termination of this option under Section 3 hereof or the
Plan. If the foregoing schedule would produce fractional Ordinary Shares, the number of Ordinary Shares for
which the option vests shall be rounded down to the nearest whole Ordinary Share.

(c)

Notwithstanding the provisions of paragraph (a) above, the option shall automatically accelerate

and become fully vested if a Reorganization Event (as defined in the Plan) occurs before the option is fully vested
and while the Participant is an Eligible Participant, the option shall automatically accelerate and become fully
vested immediately prior to the date of the Reorganization Event.

3.

Exercise of Option.

(a)

Form of Exercise.  Each election to exercise this option shall be in writing, signed by the 

Participant, and received by the Company at its principal office, accompanied by this agreement, or by such other 
method as shall be approved by the Company, in each case together with payment in full in the manner provided 
in the Plan.  The Participant may purchase less than the number of shares covered hereby, provided that no 
partial exercise of this option may be for any fractional share or for fewer than ten whole shares.

(b)

Continuous Relationship with the Company Required.  Except as otherwise provided in this 

Section 3, this option may not be exercised unless the Participant, at the time he or she exercises this option, is, 
and has been at all times since the Award Date, an employee, officer or a director of, or consultant or advisor (as 
such terms are defined for purposes of Form S-8 under the Securities Act of

1933, as amended) to, the Company or any parent or subsidiary of the Company (an “Eligible Participant”).

(c)

Termination of Relationship with the Company.  If the Participant ceases to be an Eligible 

Participant for any reason, then, except as provided in paragraphs (d) and (e) below, the right to exercise this 
option shall terminate six months after such cessation (but in no event after the Final Exercise Date), provided
that this option shall be exercisable only to the extent that the Participant was entitled to exercise this option on 
the date of such cessation.  Notwithstanding the foregoing, if the Participant, prior to the Final Exercise Date, 
violates the non-competition or confidentiality provisions of any employment contract, confidentiality and 
nondisclosure agreement or other agreement between the Participant and the Employer, the right to exercise this 
option shall terminate immediately upon written notice to the Participant from the Employer describing such 
violation.

(d)

Exercise Period Upon Death or Disability.  If the Participant dies or becomes disabled (within the 

meaning of Section 22(e)(3) of the Code) prior to the Final Exercise Date while he or she is an Eligible Participant 
and the Employer has not terminated such relationship for Cause as specified in paragraph (e) below, this option 
shall be exercisable, within the period of one year following the date of death or disability of the Participant, by 
the Participant (or in the case of death by an authorized transferee), provided that this option shall be exercisable
only to the extent that this option was exercisable by the Participant on the date of his or her death or disability
(including as provided in Section 2(c)), and further provided that this option shall not be exercisable after the
Final Exercise Date.

(e)

Termination for Cause.  If, prior to the Final Exercise Date, the Participant’s employment is 
terminated by the Employer for Cause (as defined below), the right to exercise this option shall terminate 
immediately upon the effective date of such termination of employment.  If, prior to the Final Exercise Date, the 
Participant is given notice by the Employer of the termination of his or her employment by the Employer for 
Cause, and the effective date of such employment or other termination is subsequent to the date of delivery of 
such notice, the right to exercise this option shall be suspended from the time of the delivery of such notice until 
the earlier of (i) such time as it is determined or otherwise agreed that the Participant’s employment shall not be 
terminated for Cause as provided in such notice or (ii) the effective date of such termination of employment (or 
other relationship) (in which case the right to exercise this option shall, pursuant to the preceding sentence, 
terminate upon the effective date of such termination of employment).  If the Participant is party to an 
employment, consulting or severance agreement with the Employer that contains a definition of “cause” for 
termination of employment, “Cause” shall have the meaning ascribed to such term in such agreement.  
Otherwise, “Cause” shall mean willful misconduct by the Participant or willful failure by the Participant to perform 
his or her responsibilities to the Employer (including, without limitation, breach by the Participant of any provision 
of any employment, consulting, advisory, nondisclosure, non-competition or other similar agreement between the 
Participant and the Employer), as determined by the Employer, which determination shall be conclusive.  The 
Participant’s employment (or other relationship) shall be considered to have been terminated for Cause if the 
Employer determines, within 30 days after the Participant’s resignation, that termination for Cause was 
warranted.

4.

Tax Matters.

(a)

Withholding.  No Ordinary Shares will be issued pursuant to the exercise of this option unless and 

until the Participant pays to the Employer, or makes provision satisfactory to the Employer

for payment of, any national, federal, state and local or other income, national insurance, social and employment
taxes required by law to be withheld in respect of this option.

5.

Transfer Restrictions.

This option may not be sold, assigned, transferred, pledged or otherwise encumbered by the Participant,

either voluntarily or by operation of law, except by will or the laws of descent and distribution, and, during the
lifetime of the Participant, this option shall be exercisable only by the Participant.

6.

Provisions of the Plan.

This option is subject to the provisions of the Plan (including the provisions relating to amendments to the

Plan), a copy of which is furnished to the Participant with this option.

7.

Nature of the Grant.

In accepting the option, the Participant acknowledges that:

(a)

the  Plan  is  established  voluntarily  by  the  Company,  it  provides  for  certain  criteria  in  order  to  be
eligible to receive an award, it is restricted in time, it is discretionary in nature and it may be modified, amended,
suspended or terminated by the Company at any time, unless otherwise provided in the Plan and this agreement;

(b)

the grant of the option is voluntary and occasional and does not create any contractual or other
right  to  receive  future  grants  of  options,  or  benefits  in  lieu  of  options,  even  if  options  have  been  granted
repeatedly in the past;

(c)

all  decisions  with  respect  to  future  option  grants,  if  any,  will  be  at  the  sole  discretion  of  the

Management Board;

(d)

the Participant is voluntarily participating in the Plan;

(e)

the  options  are  an  extraordinary  item  that  does  not  constitute  compensation  of  any  kind  for
services  of  any  kind  rendered  to  the  Company  or  the  Employer  and  which  is  outside  the  scope  of  the
Participant’s employment or consultancy agreement of his or her corporate mandate, if any;

(f)

the options are not part of normal or expected compensation or salary for any purposes, including,
but not limited to, calculation of any severance, resignation, termination, redundancy, end of service payments,
bonuses, long-service awards, pension, retirement or welfare benefits or similar payments and in no event should
be considered as compensation for, or relating in any way, to past services for the Company or the Employer;

(g)

in  the  event  that  the  Participant  is  not  an  employee  of  uniQure  N.V.,  the  options  and  the
Participant’s  participation  in  the  Plan  will  not  be  interpreted  to  form  an  employment  or  service  contract  or
relationship with the Company;

(h)

the  future  value  of  the  underlying  Ordinary  Shares  is  unknown  and  cannot  be  predicted  with

certainty; if the Participant’s options never vest, the Participant will not be able to exercise the options; and

(i)

in  consideration  of  the  options,  no  claim  or  entitlement  to  compensation  or  damages  shall  arise
from termination of the options or from any decrease in value of the options or Ordinary Shares acquired upon
exercise  of  the  options  resulting  from  termination  of  the  Participant’s  employment,  consultancy  or  corporate
mandate by or with the Company or the Employer (for any reason whatsoever and whether or not in breach of
contract  or  local  laws)  and  the  Participant  irrevocably  releases  the  Company  and  the  Employer  from  any  such
claim that may arise.

8.

Data Privacy.

The  Participant  hereby  explicitly  and  unambiguously  consents  to  the  collection,  use  and  transfer,  in
electronic or other form, of his or her personal data as described in this agreement by and among, as applicable,
his  or  her  Employer  or  contracting  party  and  the  Company  for  the  exclusive  purpose  of  implementing,
administering and managing his or her participation in the Plan.

The  Participant  understands  that  the  Company  holds  certain  personal  information  about  him  or  her,

cancelled, exercised, vested, unvested or outstanding in the Participant’s favor, for the purpose of implementing,
administering and managing the Plan (“Personal Data”).  The Participant understands that Personal Data may be
transferred to any third parties assisting in the implementation, administration and management of the Plan, that
these  recipients  may  be  located  in  the  Participant’s  country  or  elsewhere,  and  that  the  recipient’s  country  may
have different data privacy laws and protections than the Participant’s country.  The Participant understands that
he or she may request a list with the names and addresses of any potential recipients of the Personal Data by
contacting his or her local human resources representative. The Participant authorizes the recipients to receive,
possess, use, retain and transfer the Personal Data, in electronic or other form, for the purposes of implementing,
administering and managing his or her participation in the Plan, including any requisite transfer of such Personal
Data  as  may  be  required  to  a  broker  or  other  third  party  with  whom  the  Participant  may  elect  to  deposit  any
Ordinary Shares acquired upon exercise of the options. The Participant understands that Personal Data will be
held only as long as is necessary to implement, administer and manage his or her participation in the Plan.  The
Participant understands that he or she may, at any time, view Personal Data, request additional information about
the storage and processing of Personal Data, require any necessary amendments to Personal Data or refuse or
withdraw the consents herein, in any case without cost, by contacting in writing his or her local human resources
representative. The Participant understands, however, that refusing or withdrawing his or her consent may affect
his or her ability to participate in the Plan.  For more information on the consequences of Participant’s refusal to
consent or withdrawal of consent, the Participant understands that he or she may contact his or her local human
resources representative.

Exhibit B.

(b)

written employment agreement, the Participant’s resignation for Good Reason (as defined in such employment
agreement), as of the Vesting Date, the Participant shall be entitled to the number of Performance-Based
Restricted Share Units earned pursuant to the Performance Goals as of the date of termination.

between the Participant and the Employer), as determined by the Employer, which determination shall be
conclusive. The Participant’s employment shall be considered to have been terminated for Cause if the Employer

warranted.

Company on the first business day following the date that the Performance-Based Restricted Share Units vest (the

notice at least 30 business days prior to the Settlement Date authorizing the Company to cause to be sold a certain 
percentage of the Ordinary Shares so vesting, provided that the Participant does not possess any material non-
public information that would preclude such a change under the Company’s insider trading policy in effect at the 
time of such notice.

8.
by or in the employ or service of the Employer and shall not interfere in any way with the right of the Employer to 
terminate the Participant’s employment or service at any time.  The right of the Employer to terminate the

The vested share outcome will be modified based on uniQure’s relative total shareholder return (“TSR”)
performance for the following goals:

·
·
·

[***].
[***].
[***].

The relative TSR modifier is a comparison of the TSR of uniQure’s ordinary shares from the Award Date through
and including the third anniversary of the Award Date (the “TSR Performance Period”). The Peer Group
companies will be defined as constituent companies of the NASDAQ Biotechnology Index on December 8, 2021,
which includes uniQure. uniQure’s

-7-

percentile rank within the list will determine the modifier that is applied to the payout achieved in respect of the
Performance Goals.

TSR means the total return to the holders of ordinary shares or units of common stock in the capital of uniQure or
any other Peer Group company during the Performance Period based on:

·
·

share price appreciation; and
the assumed reinvestment of dividends on the ex-dividend date.

TSR will be calculated in a common currency of US Dollars and expressed as a percentage.  The Performance 
Period will start on December 9, 2021 and conclude on the later of the third anniversary of the Award Date.

TSR shall be calculated for each member of the Peer Group using the closing share prices as listed on the
Nasdaq, or, if not available, using an independent source of such data as approved by the Compensation
Committee of the Company’s Board of Directors, where:

TSR =

(Closing Share Price Average- Starting Price) + Dividends
Starting Share Price Average

Closing Share Price Average: For each company in the peer group (including Company), the average of the daily
Adjusted  Close  Price  during  the  Averaging  Period,  where  the  Averaging  Period  ends  on  the  last  day  of  the
Performance Period;

Starting Share Price Average: the average of the daily Adjusted Close Price during the Averaging Period, where
the Averaging Period ends on the Award Date, inclusive;

Averaging Period: 30 consecutive trading days; and

Adjusted Close Price: the closing share price of a stock of a company in the Peer Group adjusted for the impact
of dividends reinvested following the ex-dividend date.

Peer Group companies may be removed from the group or dropped to the bottom of the group for the purpose of
determining relative ranks in the event of unusual trading activity. In particular:

· Companies who are suspended or delisted for reasons such as financial insolvency, bankruptcy or no

longer meeting the minimum requirements to be a constituent of the index will remain in Peer Group and
be ranked at the bottom of the Peer Group

· Companies who are acquired by or merge with another company in the Peer Group shall be retained with
the TSR measurement calculation based on the performance of the surviving stock exchange ticker, and
the Company associated with the discontinued stock exchange ticker will be removed from the Peer
Group; and

· Companies who are acquired by another company outside of the Peer Group or who cease to be listed for
reasons other than poor performance will be removed from the Peer Group due to the lack of available
data for the point after the acquisition.

-8-

The Compensation Committee will approve all Peer Group adjustments, have the ability to approve any other
adjustments to the Peer Group as a result of unusual trading activity not contemplated above, and have the
discretion to approve alternative approaches to those described above if appropriate and in the spirit of the intent
of the program.

The total number of vested shares awarded for specific goal will be adjusted on a goal-by-goal basis by
multiplying the total number of shares that would vest in conjunction with that goal by the Modifier as provided in
the table below, based on Company’s percentile ranking within the Peer Group per the following:

uniQure’s ranking within the Peer Group

75th Percentile or higher

25th Percentile or higher, up to but not including the 75th Percentile

Below the 25th Percentile

Modifier

1.50

1.00

0.50

For the avoidance of doubt, the 75th percentile and above is the top quartile in the group, reflecting the highest
performing companies; the 25th percentile and below is the lowest quartile in the group, reflecting the poorest
performing companies.

Based on the TSR modifier outlined above, the “Maximum Award” available pursuant to this award is 132.5% of
the Target Award.

Vesting Schedule:  Any fractional Performance-Based Restricted Share Units resulting from the achievement of
the Performance Goals in accordance with the terms herein shall be rounded down to the nearest whole number.

If Performance-Based Restricted Share Units are not earned on or before the last day of the Performance Period,
they will be forfeited as of such date.

Notwithstanding the foregoing, if a Reorganization Event occurs before the last day of the Performance Period,
the number of Performance-Based Restricted Share Units equal to the Target Award shall become fully earned at
target and vested immediately prior to a Reorganization Event, if the Participant is employed by the Employer on
the date of the Reorganization Event. If a Reorganization Event occurs after the end of the Performance Period but
before the Vesting Date, the earned Performance-Based Restricted Share Units will become fully vested
immediately prior to a Reorganization Event, if the Participant is employed by the Employer on date of the
Reorganization Event.

Issuance Schedule:  The Participant will receive a distribution with respect to the Performance- Based Restricted
Share Units earned and vested pursuant to this Agreement, if any, on the earlier to occur of the first business day
following the Vesting Date or the date of the consummation of a Reorganization Event that meets the requirements
of a “change in control event” under Section 409A of the Code (“Payment Date”).  Distribution will be made 
with respect to the Performance-Based Restricted Share Units on the Payment Date in Ordinary Shares, with each 
Performance-Based Restricted Share Units earned and vested equivalent to one Ordinary Share. In no event shall 
any fractional shares be issued.  Unless otherwise indicated in the Agreement or

-9-

as otherwise determined by the Board, the Participant must be employed by the Employer on the Vesting Date in
order to earn and vest in any of the Performance-Based Restricted Share Units.

Participant must sign this agreement within 90 days of the Award Date as set forth on the applicable Notice of
Grant by clicking on the button “I Accept”. The plan agreement will then be stored under the “Grants & Awards”

SECTION 2. THE LOANS

2.1       Term Loan.

(a)          Term Loan Advance.  Subject  to  the  terms  and  conditions  of  this  Agreement,  the  Lenders
agree severally (and not jointly) to make, in an amount not to exceed their respective Term Loan Commitment,
and Borrower agrees to draw, a Term Loan Advance in an aggregate principal amount of One Hundred Million
Dollars  ($100,000,000)  on  the  Restatement  Date.  Concurrently  with  the  drawing  of  the  Term  Loan  Advance,
Borrower shall prepay the aggregate outstanding principal amount of the 2018 Term Loan Advance and the 2021
Term  Loan  Advance  (which  prepayment  shall  be  netted  from  the  Term  Loan  Advance  disbursed  by  Lender  to
Borrower on the Restatement Date).

(b)          Outstanding  Principal  Amount;  Termination  of  Commitments.  The  parties  hereto
acknowledge and agree that: (i) immediately prior to the Restatement Date, the aggregate outstanding principal
amount of the 2018 Term Loan Advances is Thirty-Five Million Dollars ($35,000,000), (ii) immediately prior to
the Restatement Date, the aggregate outstanding principal amount of the 2021 Term Loan Advances is Thirty-Five
Million  Dollars  ($35,000,000),  (iii)  Borrower  shall  not  be  permitted  to  draw,  and  Lender  shall  not  make,  any
further  2018  Term  Loan  Advances  or  2021  Term  Loan  Advances  and  (iii)  contemporaneously  with  the
disbursement of the Term Loan Advance on the Restatement Date, each of the 2018 Term Loan Commitment and
2021 Term Loan Commitment shall automatically be terminated without further action from any Person.

(c)          Advance  Request.  To  obtain  a  Term  Loan  Advance,  Borrower  shall  complete,  sign  and
deliver  an  Advance  Request  (at  least  one  (1)  Business  Day  before  the  Restatement  Date  and  at  least  five  (5)
Business Days before each Advance Date other than the Restatement Date) to Agent. Lender shall fund its ratable
portion of each Term Loan Advance in the manner requested by the Advance Request provided that each of the
conditions precedent to such Term Loan Advance is satisfied as of the requested Advance Date.

(d)     Interest. The principal balance of each Term Loan Advance shall bear interest thereon from
such Advance Date at the Term Loan Interest Rate based on a year consisting of 360 days, with interest computed
daily based on the actual number of days elapsed. The Term Loan Interest Rate will float and change on the day
the Prime Rate changes from time to time.

(e)     Payment. Borrower will pay interest on each Term Loan Advance on the first (1st) Business
Day of each month, beginning the month after the Advance Date. If (i) the Performance Milestone has not been
met,  Borrower  shall  repay  the  aggregate  Term  Loan  Advance  that  is  outstanding  on  the  day  immediately
preceding  the  Amortization  Date,  in  equal  monthly  installments  of  principal  and  interest  (mortgage  style)
beginning on the Amortization Date and continuing on the first Business Day of each month thereafter until the
Secured  Obligations  (other  than  inchoate  indemnity  obligations)  are  repaid;  provided  that  any  remaining
outstanding Term

14

Loan Advance and all accrued but unpaid interest hereunder, shall be due and payable on the Term Loan Maturity
Date; and (ii) the Performance Milestone has been met, the entire principal balance of the Term Loan Advance
and any accrued but unpaid interest thereon hereunder, shall be due and payable on the Term Loan Maturity Date.
Borrower shall make all payments under this Agreement without setoff, recoupment or deduction and regardless
of any counterclaim or defense. Lender will initiate debit entries to the Borrower’s account as authorized on the
ACH  Authorization  on  each  payment  date  of  all  periodic  obligations  payable  to  Lender  under  each  Term  Loan
Advance. Once repaid, the Term Loan Advances or any portion thereof may not be reborrowed.

2.2       Maximum Interest. Notwithstanding any provision in this Agreement or any other Loan Document,
it is the parties’ intent not to contract for, charge or receive interest at a rate that is greater than the maximum rate
permissible by law that a court of competent jurisdiction shall deem applicable hereto (which under the laws of
the State of California shall be deemed to be the laws relating to permissible rates of interest on commercial loans)
(the “Maximum Rate”).  If  a  court  of  competent  jurisdiction  shall  finally  determine  that  Borrower  has  actually
paid to Lender an amount of interest in excess of the amount that would have been payable if all of the Secured
Obligations  had  at  all  times  borne  interest  at  the  Maximum  Rate,  then  such  excess  interest  actually  paid  by
Borrower  shall  be  applied  as  follows:  first,  to  the  payment  of  the  Secured  Obligations  consisting  of  the
outstanding principal of the Term Loan Advances; second, after all principal is repaid, to the payment of Lender's
accrued interest, costs, expenses, professional fees and any other Secured Obligations; and third, after all Secured
Obligations are repaid, the excess (if any) shall be refunded to Borrower.

2.3       Default Interest. In the event any payment is not paid on the scheduled payment date, an amount
equal to five percent (5%) of the past due amount shall be payable on demand. In addition, upon the occurrence
and  during  the  continuation  of  an  Event  of  Default  hereunder,  all  Secured  Obligations,  including  principal,
interest, compounded interest, and professional fees, shall bear interest at a rate per annum equal to the rate set
forth  in  Section  2.1(d),  plus  five  percent  (5%)  per  annum.  In  the  event  any  interest  is  not  paid  when  due
hereunder,  delinquent  interest  shall  be  added  to  principal  and  shall  bear  interest  on  interest,  compounded  at  the
rate set forth in Section 2.1(d).

2.4              Prepayment.  At  its  option,  upon  at  least  five  (5)  Business  Days  prior  written  notice  to  Agent,
Borrower  may  prepay  the  whole  or  part  (but  in  an  amount  not  less  than  $50,000,000  or  less  if  the  applicable
amount of outstanding Term Loan Advances are less than $50,000,000 at such time) the outstanding Term Loan
Advances including all accrued and unpaid interest thereon, all unpaid Lender's fees and expenses accrued to the
date of the repayment (including, without limitation, the End of Term Charge) together with a prepayment charge
equal to the following percentage of the amount of the Term Loan Advances being prepaid: if such Term Loan
Advance amounts are prepaid in any of the first twenty-four (24) months following the Restatement Date, one and
one half percent (1.50%); and thereafter, zero percent (0.00%) (each, a “Prepayment Charge”). Borrower agrees
that  the  Prepayment  Charge  is  a  reasonable  calculation  of  Lender's  lost  profits  in  view  of  the  difficulties  and
impracticality  of  determining  actual  damages  resulting  from  an  early  repayment  of  the  Term  Loan  Advances.
Upon  the  occurrence  of  a  Change  in  Control,  Borrower  shall  immediately  prepay  the  aggregate  outstanding
amount of all principal of all Term Loan Advances and accrued interest thereon through the prepayment date and
all unpaid

15

Lender's fees and expenses accrued to the date of the prepayment (including, without limitation, the End of Term
Charge) together with the Prepayment Charge. Notwithstanding the foregoing, Agent and Lender agree to waive
the Prepayment Charge if Agent and Lender (in their sole and absolute discretion) agree in writing to refinance the
Term Loan Advances prior to the Term Loan Maturity Date. For the avoidance of doubt, Lender and Agent agree
that  the  Term  Loan  Advance  made  hereunder  does  not  constitute  a  prepayment  of  the  Existing  Term  Loan
Advances and no Prepayment Charge shall be payable on the Restatement Date.

2.5       Original End of Term Charges.

(a)          On  the  earliest  to  occur  of  (i)  June  1,  2023,  (ii)  the  date  that  Borrower  prepays  the
outstanding Secured Obligations, or (iii) the date that the Secured Obligations become due and payable, Borrower
shall pay Lender a charge equal to $1,732,500 (the “2018 End of Term Charge”). Notwithstanding the required
payment  date  of  such  charge,  the  2018  End  of  Term  Charge  shall  be  deemed  earned  by  Lender  as  of  the  2018
Closing Date.

(b)          On  the  earliest  to  occur  of  (i)  June  1,  2023,  (ii)  the  date  that  Borrower  prepays  the
outstanding Secured Obligations, or (iii) the date that the Secured Obligations become due and payable, Borrower
shall pay Lender a charge equal to $787,500 (the “2021 End of Term Charge”).  Notwithstanding  the  required
payment  date  of  such  charge,  the  2021  End  of  Term  Charge  shall  be  deemed  earned  by  Lender  as  of  the  2021
Closing Date.

2.6       Additional End of Term Charge. On the earliest to occur of (i) Term Loan Maturity Date, (ii) the
date  that  Borrower  prepays  the  outstanding  Secured  Obligations,  or  (iii)  the  date  that  the  Secured  Obligations
become  due  and  payable,  Borrower  shall  immediately  pay  Lender  an  additional  charge  equal  to  4.85%  of  the
aggregate  outstanding  principal  amount  of  the  Term  Loan  Advances  as  of  such  date  (the  “Term  Loan  End  of
Term Charge” and, together with the 2018 End of Term Charge and the 2021 End of Term Charge, the “End of
Term Charge”). Notwithstanding the required payment date of such Term Loan End of Term Charge, it shall be
deemed earned by Lender as of the Restatement Date.

2.7       Notes. If so requested by Lender by written notice to Borrower, then Borrower shall execute and
deliver  to  Lender  (and/or,  if  applicable  and  if  so  specified  in  such  notice,  to  any  person  who  is  an  assignee  of
Lender  pursuant  to  Section  10.12)  (promptly  after  the  Borrower’s  receipt  of  such  notice)  a  Note  or  Notes  to
evidence a Term Loan Advance made by Lender.

2.8              Pro  Rata  Treatment.  Each  payment  (including  prepayment)  on  account  of  any  fee  and  any
reduction  of  the  Term  Loan  Advances  shall  be  made  pro  rata  according  to  such  Term  Loan  Advance  of  the
relevant Lender.

SECTION 3. SECURITY INTEREST

3.1       As security for the prompt, complete and indefeasible payment when due (whether on the payment

dates or otherwise) of all the Secured Obligations:

(a)     uniQure Holdings grants to Lender a first ranking right of pledge on its shares in Corlieve

Therapeutics, uniQure Bio and uniQure IP;

16

(b)          uniQure  Bio  grants  to  Lender  a  first  ranking  right  of  pledge  on  its  shares  in  its  Dutch
subsidiaries  identified  on  the  Schedule  1  hereto  and  a  security  interest  in  100%  of  the  capital  stock  of  US
Borrower;

(c)     Obligor (excluding US Borrower) grants to Lender a first ranking right of pledge on its (a)

trade, intercompany and insurance receivables; (b) movable assets and (c) Deposit Accounts; and

(d)          US  Borrower  grants  to  Lender  a  security  interest  in  all  of  US  Borrower’s  right,  title,  and
interest in and to the following personal property whether now owned or hereafter acquired: (a) receivables; (b)
equipment;  (c)  fixtures;  (d)  general  intangibles  (except  as  described  below);  (e)  inventory;  (f)  Investment
Property; (g) Deposit Accounts; (h) Cash; (i) Goods; and all other tangible and intangible personal property of US
Borrower whether now or hereafter owned or existing, leased, consigned by or to, or acquired by, US Borrower
and wherever located, and any of US Borrower’s property in the possession or under the control of Lender; and, to
the  extent  not  otherwise  included,  all  proceeds  of  each  of  the  foregoing  and  all  accessions  to,  substitutions  and
replacements  for,  and  rents,  profits  and  products  of  each  of  the  foregoing,  (a),  (b),  (c)  and  (d)  collectively,  the
“Collateral”.

3.2       Notwithstanding anything in this Agreement or any other Loan Document to the contrary, in no
event shall the Collateral include, and the Obligor shall not be deemed to have granted a security interest in: (i)
Intellectual Property; provided, however, that the Collateral shall include all accounts and general intangibles that
consist of rights to payment and proceeds from the sale, licensing or disposition of all or any part, or rights in, the
Intellectual Property (the “Rights to Payment”); or (ii) any of the Borrower’s rights or interests in or under, any
license, contract, permit, instrument, security or franchise to which the Borrower is a party or any of its rights or
interests thereunder to the extent, but only to the extent, that such a grant would, under the terms of such license,
contract, permit, instrument, security or franchise, result in a breach of the terms of, or constitute a default under,
such license, contract, permit, instrument, security or franchise (other than to the extent that any such term would
be  rendered  ineffective  pursuant  to  the  UCC  or  any  other  applicable  law  (including  the  Dutch  and  the  United
States  Bankruptcy  Code)  or  principles  of  equity);  provided,  that  immediately  upon  the  ineffectiveness,  lapse  or
termination of any such provision the Collateral shall include, and the Borrower shall be deemed to have granted a
security interest in, all the rights and interests described in the foregoing clause (ii) as if such provision had never
been in effect. Notwithstanding the foregoing, if a judicial authority (including a U.S. Bankruptcy Court) holds
that a security interest in the underlying Intellectual Property is necessary to have a security interest in the Rights
to  Payment,  then  the  Collateral  shall  automatically,  and  effective  as  of  the  date  of  this  Agreement,  include  the
Intellectual  Property  to  the  extent  necessary  to  permit  perfection  of  Lender’s  security  interest  in  the  Rights  to
Payment.

with the passage of time, the giving of notice, or both) constitute an Event of Default and (ii) no event that has had
or could reasonably be expected to have a Material Adverse Effect has occurred and is continuing.

could reasonably be expected to have a Material Adverse Effect. uniQure Bio’s present name, former names (if
any),  locations,  place  of  formation,  tax  identification  number,  organizational  identification  number  and  other
information are correctly set forth in Exhibit C, as may be updated by uniQure Bio in a written notice (including

organized, legally existing and in good standing under the laws of the State of Delaware, and is duly qualified as a
foreign corporation in all jurisdictions in which the nature of its business or location of its properties require such

Effect.

5.2       Collateral. The relevant Obligor owns the Collateral and the Intellectual Property, free of all Liens,
except for Permitted Liens. Each Obligor has the power and authority to grant to Lender a Lien in the Collateral as
security for the Secured Obligations.

5.3       Consents. Borrower’s execution, delivery and performance of the Notes (if any), this Agreement
and all other Loan Documents, (i) have been duly authorized by all necessary corporate action of Borrower, (ii)
will not result in the creation or imposition of any Lien upon the Collateral, other than Permitted Liens and the

executing the Loan Documents are duly authorized to do so.

5.4       Material Adverse Effect. No event that has had or could reasonably be expected to have a Material
Adverse  Effect  has  occurred  and  is  continuing.  Borrower  is  not  aware  of  any  event  likely  to  occur  that  is
reasonably expected to result in a Material Adverse Effect.

prevent, enjoin, hinder or delay the transactions contemplated by the Loan Documents or (ii) as to which there is a
reasonable  possibility  of  an  adverse  determination  and  which,  if  adversely  determined,  would  reasonably  be

nor any of its Subsidiaries is engaged as one of its important activities in extending credit for margin stock (under
Regulations  X,  T  and  U  of  the  Federal  Reserve  Board  of  Governors,  as  applicable).  Borrower  and  each  of  its
Subsidiaries  has  complied  in  all  material  respects  with  the  Federal  Fair  Labor  Standards  Act,  as  applicable.
Neither Borrower nor any of its Subsidiaries is a “holding company” or an “affiliate” of a “holding company” or a
“subsidiary  company”  of  a  “holding  company”  as  each  term  is  defined  and  used  in  the  Public  Utility  Holding

used by Borrower or such Subsidiary or, to Borrower’s knowledge, by previous Persons, in disposing, producing,
storing, treating, or transporting any hazardous substance other than in material compliance with applicable laws.

prohibitions  set  forth  in  any  Anti-Terrorism  Law,  or  (iii)  is  a  Blocked  Person.  None  of  Borrower,  any  of  its
Subsidiaries,  or  to  the  knowledge  of  Borrower  and  any  of  their  Affiliates  or  agents,  acting  or  benefiting  in  any

Corrupt Practices Act of 1977, as amended.

5.7       Information Correct and Current. No information, report, Advance Request, financial statement,
exhibit or schedule furnished, by or on behalf of Borrower to Lender in connection with any Loan Document or
included therein or delivered pursuant thereto contained, contains or will contain any material misstatement of fact
or omitted, omits or will omit to state any material fact necessary to make the statements therein, in the light of the
circumstances under which they were, are or will be made, not misleading at the time such statement was made or
deemed made. Additionally, any and all financial or business projections provided by Borrower to Lender shall be
(i) provided in good faith and based on the most current data and information available to Borrower, (ii) the most
current  of  such  projections  provided  to  the  Board,  and  (iii)  are  based  on  reasonable  assumptions  not  viewed  as
facts and that actual results during the period or periods covered by such projections and forecast may differ from
the projected or forecasted results.

5.8       Tax Matters. Except as described on Schedule 5.8, (a) Borrower has filed all federal, state and local
tax  returns  that  it  is  required  to  file,  (b)  Borrower  has  duly  paid  or  fully  reserved  for  all  taxes  or  installments
thereof (including any interest or penalties) as and when due, which have or may become due pursuant to such
returns, and (c) Borrower has paid or fully reserved for any tax assessment received by Borrower for the three (3)
years preceding the Restatement Date, if any (including any taxes being contested in good faith and by appropriate
proceedings).

5.9       Intellectual Property Claims. Borrower is the sole owner of, or otherwise has the right to use, the
Intellectual Property. Except as described on Schedule 5.9, (i) each of the material Copyrights, Trademarks and
Patents  is  valid  and  enforceable,  (ii)  no  material  part  of  the  Intellectual  Property  has  been  judged  invalid  or
unenforceable, in whole or in part, and (iii) no claim has been made in writing to Borrower that any material part
of the Intellectual Property violates the rights of any third party. Exhibit D is a true, correct and complete list of
each of Borrower’s Patents, registered Trademarks, registered Copyrights, and material agreements under which
Borrower  licenses  Intellectual  Property  from  third  parties  (other  than  shrink-wrap  software  licenses  and  other
licenses for over-the-counter software), together with application or registration numbers, as applicable, owned by
Borrower or any Subsidiary, in each case as of the Restatement Date. Borrower is not in material breach of, nor
has  Borrower  failed  to  perform  any  material  obligations  under,  any  of  the  foregoing  contracts,  licenses  or
agreements and, to uniQure Holdings’ knowledge, no third party to any such contract, license or agreement is in
material breach thereof or has failed to perform any material obligations thereunder.

5.10     Intellectual Property. Except as described on Schedule 5.10, Borrower has, or in the case of any
proposed business, will have, all material rights with respect to Intellectual Property necessary in the operation or
conduct  of  Borrower’s  business  as  currently  conducted  and  proposed  to  be  conducted  by  Borrower,  Without
limiting the generality of the foregoing, and in the case of Licenses, except for restrictions that are unenforceable
under  Division  9  of  the  UCC,  Borrower  has  the  right,  to  the  extent  required  to  operate  Borrower’s  business,  to
freely transfer, license or assign Intellectual Property without condition, restriction or payment of any kind (other
than

21

license payments in the ordinary course of business) to any third party, and Borrower owns or has the right to use,
pursuant  to  valid  licenses,  all  software  development  tools,  library  functions,  compilers  and  all  other  third-party
software  and  other  items  that  are  necessary  in  the  design,  development,  promotion,  sale,  license,  manufacture,
import, export, use or distribution of Borrower Products.

5.11          Borrower  Products.  Except  as  described  on  Schedule  5.11,  no  Intellectual  Property  owned  by
Borrower or Borrower Product has been or is subject to any actual or, to the knowledge of Borrower, threatened
litigation, proceeding or outstanding decree, order, judgment, settlement agreement or stipulation that restricts in
any material manner Borrower’s use, transfer or licensing thereof or that may materially affect the validity, use or
enforceability  thereof.  There  is  no  decree,  order,  judgment,  agreement,  stipulation,  arbitral  award  or  other
provision entered into in connection with any litigation or proceeding that obligates Borrower to grant licenses or
ownership  interest  in  any  future  Intellectual  Property  related  to  the  operation  or  conduct  of  the  business  of
Borrower or Borrower Products. Borrower has not received any written notice or claim, or, to the knowledge of
Borrower, oral notice or claim, challenging or questioning Borrower’s ownership in any Intellectual Property (or
written notice of any claim challenging or questioning the ownership in any licensed Intellectual Property of the
owner  thereof)  or  suggesting  that  any  third  party  has  any  claim  of  legal  or  beneficial  ownership  with  respect
thereto nor, to Borrower’s knowledge, is there a reasonable basis for any such claim. To Borrower’s knowledge,
neither Borrower’s use of its Intellectual Property nor the production and sale of Borrower Products infringes the
Intellectual Property or other rights of others.

5.12     Financial Accounts. Exhibit E, as may be updated by the Borrower in a written notice provided to
Lender  after  the  Restatement  Date,  is  a  true,  correct  and  complete  list  of  (a)  all  banks  and  other  financial
institutions  at  which  Borrower  or  any  Subsidiary  maintains  Deposit  Accounts  and  (b)  all  institutions  at  which
Borrower  or  any  Subsidiary  maintains  an  account  holding  Investment  Property,  and  such  exhibit  correctly
identifies  the  name,  address  and  telephone  number  of  each  bank  or  other  institution,  the  name  in  which  the
account is held, a description of the purpose of the account, and the complete account number therefor.

5.13     Employee Loans. Borrower has no outstanding loans to any employee, officer or director of the
Borrower nor has Borrower guaranteed the payment of any loan made to an employee, officer or director of the
Borrower by a third party.

5.14     Capitalization and Subsidiaries. uniQure Holdings’ capitalization as of the Restatement Date is set
forth on Schedule 5.14 annexed hereto. uniQure Holdings does not own any stock, partnership interest or other
securities  of  any  Person,  except  for  Permitted  Investments.  Attached  as  Schedule  5.14,  as  may  be  updated  by
uniQure Holdings in a written notice provided after the Restatement Date, is a true, correct and complete list of
each Subsidiary.

5.15     Centre of main interests and establishments. uniQure Bio has its “centre of main interests” (as that
term  is  used  in  article  3(1)  of  The  Council  of  the  European  Union  Regulation  No.  1346/2000  on  Insolvency
Proceedings) in the Netherlands.

22

SECTION 6. INSURANCE; INDEMNIFICATION

6.1       Coverage. uniQure Holdings shall cause to be carried and maintained (by itself or its Subsidiaries)
commercial  general  liability  insurance,  on  an  occurrence  form,  against  risks  customarily  insured  against  in
uniQure Holdings’ line of business. Such risks shall include the risks of bodily injury, including death, property
damage,  personal  injury,  advertising  injury,  and  contractual  liability  per  the  terms  of  the  indemnification
agreement found in Section 6.3. uniQure Holdings or its Subsidiaries must maintain a minimum of $1,000,000 of
commercial general liability insurance for each occurrence and $2,000,000 in the aggregate. uniQure Holdings or
its Subsidiaries has and agrees to maintain a minimum of $2,000,000 of directors’ and officers’ insurance for each
occurrence and $5,000,000 in the aggregate. So long as there are any Secured Obligations outstanding, uniQure
Holdings shall also cause or procure that its Subsidiaries cause to be carried and maintained insurance upon the
Collateral, insuring against all risks of physical loss or damage howsoever caused, in an amount not less than the
full  replacement  cost  of  the  Collateral,  provided  that  such  insurance  may  be  subject  to  standard  exceptions  and
deductibles. uniQure Holdings or its Subsidiaries shall also carry and maintain a fidelity insurance policy in an
amount not less than $100,000.

6.2              Certificates.  uniQure  Holdings  shall  deliver  to  Lender  certificates  of  insurance  that  evidence
uniQure Holdings or its Subsidiaries compliance with its insurance obligations in Section 6.1 and the obligations
contained in this Section 6.2. uniQure Holding’s (or its Subsidiaries) insurance certificate shall state Lender is an
additional insured for commercial general liability, a loss payee for all risk property damage insurance, subject to
the insurer’s approval, a loss payee for fidelity insurance, and a loss payee for property insurance and additional
insured for liability insurance for any future insurance that uniQure Holdings or its Subsidiaries may acquire from
such insurer, unless any right under the liability insurance is restricted from being pledged under Section 7:954(4)
of  the  Dutch  Civil  Code.  Attached  to  the  certificates  of  insurance  will  be  additional  insured  endorsements  for
liability  and  lender’s  loss  payable  endorsements  for  all  risk  property  damage  insurance  and  fidelity.  Unless  an
Event  of  Default  shall  have  occurred  and  be  continuing,  all  insurance  proceeds  shall  be  paid  or  turned  over  to
uniQure Holdings or its Subsidiaries, as applicable. All certificates of insurance will provide for a minimum of
thirty (30) days advance written notice to Lender of cancellation or any other change adverse to Lender’s interests.
Any failure of Lender to scrutinize such insurance certificates for compliance is not a waiver of any of Lender’s
rights,  all  of  which  are  reserved.  Borrower  shall  provide  Agent  with  copies  of  each  insurance  policy,  and  upon
entering or amending any insurance policy required hereunder, Borrower shall provide Agent with copies of such
policies and shall promptly deliver to Agent updated insurance certificates with respect to such policies.

6.3       Indemnity. Borrower agrees to indemnify and hold Lender and its officers, directors, employees,
agents, in-house attorneys, representatives and shareholders harmless from and against any and all claims, costs,
expenses,  damages  and  liabilities  (including  such  claims,  costs,  expenses,  damages  and  liabilities  based  on
liability  in  tort:,  including  strict  liability  in  tort),  including  reasonable  documented  attorneys’  fees  and
disbursements and other costs of investigation or defense (including those incurred upon any appeal), that may be

23

hereunder and thereunder, or any actions or failures to act in connection therewith, or arising out of the disposition
or  utilization  of  the  Collateral,  excluding  in  all  cases  claims  resulting  solely  from  Lender’s  gross  negligence  or
willful misconduct Borrower agrees to pay, and to save Lender harmless from, any and all liabilities with respect
to, or resulting from any delay in paying, any and all excise, sales or other similar taxes (excluding taxes imposed
on or measured by the net income of Lender) that may be payable or determined to be payable with respect to any
of  the  Collateral  or  this  Agreement.  This  Section  6.3  shall  survive  the  repayment  of  indebtedness  under,  and
otherwise shall survive the expiration or other termination of, the Agreement.

time to time procure any instruments or documents as may reasonably be requested by Lender, and take all further
action that may be necessary or desirable, or that Lender may reasonably request, to perfect and protect the Liens
granted  hereby  and  thereby.  In  addition,  and  for  such  purposes  only,  Borrower  hereby  authorizes  Lender  to

control  agreements,  security  agreements  and  other  documents  necessary  to  grant,  perfect  and  give  the  highest

respect to any Indebtedness, or permit any Subsidiary so to do, other than Permitted Indebtedness, or prepay any
Indebtedness or take any actions which impose on Borrower an obligation to prepay any Indebtedness, except for
the  conversion  of  Indebtedness  into  equity  securities  and  the  payment  of  cash  in  lieu  of  fractional  shares  in
connection  with  such  conversion.  Borrower  shall  not  make  any  payments  under  the  Leasehold  Financing  if  an
Event of Default has occurred and is continuing.

property and assets used in Borrower’s business or in which Borrower now or hereafter holds any interest free and
clear  from  any  legal  process  or  Liens  whatsoever  (except  for  Permitted  Liens),  and  shall  give  Lender  prompt
written  notice  of  any  legal  process  affecting  the  Collateral,  the  Intellectual  Property,  such  other  property  and
assets, or any Liens thereon. Borrower shall cause its Subsidiaries to protect and defend such Subsidiary’s title to
its assets from and against all Persons claiming any interest adverse to such Subsidiary, and Borrower shall cause
its Subsidiaries at all times to keep such Subsidiary’s property and assets free and clear from any legal process or
Liens whatsoever (except for Permitted Liens), and shall give Lender prompt written notice of any legal process
affecting such Subsidiary’s assets. Borrower shall not agree with any Person other than Lender not to encumber its
property.

(b)  declare  or  pay  any  cash  dividend  or  make  a  cash  distribution  on  any  class  of  stock  or  other  equity  interest,

with all applicable laws, rules or regulations (including any law, rule or regulation with respect to the making or
brokering of loans or financial accommodations), and shall, or cause its Subsidiaries to, obtain and maintain all
required  governmental  authorizations,  approvals,  licenses,  franchises,  permits  or  registrations  reasonably
necessary in connection with the conduct of Borrower’s business.

Neither Borrower nor any of its Subsidiaries shall, nor shall Borrower or any of its Subsidiaries permit any
Affiliate to, directly or indirectly, knowingly enter into any documents, instruments, agreements or contracts with
any Person listed on the OFAC Lists. Neither Borrower nor any of its Subsidiaries shall, nor shall Borrower or any
of  its  Subsidiaries,  permit  any  Affiliate  to,  directly  or  indirectly,  (i)  conduct  any  business  or  engage  in  any
transaction  or  dealing  with  any  Blocked  Person,  including,  without  limitation,  the  making  or  receiving  of  any
contribution  of  funds,  goods  or  services  to  or  for  the  benefit  of  any  Blocked  Person,  (ii)  deal  in,  or  otherwise
engage in any transaction relating to, any property or interests in property blocked pursuant to Executive Order

by  the  Borrower,  its  Subsidiaries  and  their  respective  directors,  officers,  employees  and  agents  with  applicable
Anti-Corruption Laws and applicable Sanctions, and

28

Borrower,  its  Subsidiaries  and  their  respective  officers  and  employees  and  to  the  knowledge  of  Borrower  its
directors  and  agents,  are  in  compliance  with  applicable  Anti-Corruption  Laws  and  applicable  Sanctions  in  all
material respects.

None of Borrower, any of its Subsidiaries or any of their respective directors, officers or employees, or to
the knowledge of Borrower, any agent for Borrower or its Subsidiaries that will act in any capacity in connection
with or benefit from the credit facility established hereby, is a Sanctioned Person. No Loan, use of proceeds or
other  transaction  contemplated  by  this  Agreement  will  violate  applicable  Anti-Corruption  Laws  or  applicable
Sanctions.

7.18     Transactions with Affiliates. Borrower shall not and shall not permit any Subsidiary to, directly or
indirectly,  enter  into  or  permit  to  exist  any  transaction  of  any  kind  with  any  Affiliate  of  Borrower  or  such
Subsidiary on terms that are less favorable to Borrower or such Subsidiary, as the case may be, than those that
might  be  obtained  in  an  arm’s  length  transaction  from  a  Person  who  is  not  an  Affiliate  of  Borrower  or  such
Subsidiary; provided that no such restriction shall apply where the value of any transaction with any Affiliate of
Borrower is less than Five Hundred Thousand Dollars ($500,000).

7.19     Right to Invest. Borrower agrees that, prior to the repayment in full of all Term Loan Advances,
Lender,  any  of  its  affiliates  and/or  (subject  to  Borrower's  consent,  which  consent  shall  not  be  unreasonably
withheld,  conditioned  or  delayed)  any  other  assignees  or  nominees,  shall  have  the  right,  in  their  discretion,  to
invest up to an aggregate amount of $5,000,000 in any Subsequent Financing on the same terms, conditions and
pricing afforded to others participating in any such Subsequent Financing, provided, however, that such aggregate
amount  for  any  such  Subsequent  Financing  may  be  reduced  to  an  amount  determined  in  good  faith  by  the
managing  underwriter  of  any  such  Subsequent  Financing  if  such  managing  underwriter  determines,  in  its
reasonable  discretion,  that  such  reduction  is  required  as  a  result  of  bona  fide  marketing  factors.  Borrower  shall
notify Lender within twenty-four (24) hours of the public announcement of any such Subsequent Financing and
Lender  shall  notify  Borrower  of  its  intention  to  participate  in  such  Subsequent  Financing  as  soon  as  possible
thereafter, but in any event, not later than eight (8) hours prior to the pricing of such Subsequent Financing.

applicable  laws  and  regulations,  including  (for  the  avoidance  of  doubt)  payment  of  taxes;  provided  that  such
Investments under this clause (ii) may not be made if the aggregate amount on deposit in the Corlieve Operating

entire agreement and understanding of the parties hereto in respect of the subject matter hereof and thereof, and
supersede  and  replace  in  their  entirety  any  prior  proposals,  term  sheets,  non-  disclosure  or  confidentiality
agreements,  letters,  negotiations  or  other  documents  or  agreements,  whether  written  or  oral,  with  respect  to  the
subject matter hereof or thereof (including Lender’s proposal letter dated November 8, 2018). None of the terms
of  this  Agreement  or  any  of  the  other  Loan  Documents  may  be  amended  except  by  an  instrument  executed  by

33

10.4     No Strict Construction. The parties hereto have participated jointly in the negotiation and drafting
of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be
construed as if drafted jointly by the parties hereto and no presumption or burden of proof shall arise favoring or
disfavoring any party by virtue of the authorship of any provisions of this Agreement.

10.5     No Waiver. The powers conferred upon Lender by this Agreement are solely to protect its rights
hereunder and under the other Loan Documents and its interest in the Collateral and shall not impose any duty
upon Lender to exercise  any  such  powers.  No  omission  or  delay  by  Lender  at any time to enforce any right or
remedy reserved to it, or to require performance of any of the terms, covenants or provisions hereof by Borrower
at any time designated, shall be a waiver of any such right or remedy to which Lender is entitled, nor shall it in
any way affect the right of Lender to enforce such provisions thereafter.

10.6     Survival. All agreements, representations and warranties contained in this Agreement and the other
Loan Documents or in any document delivered pursuant hereto or thereto shall be for the benefit of Lender and
shall  survive  the  execution  and  delivery  of  this  Agreement  and  the  expiration  or  other  termination  of  this
Agreement.

consent, and any such attempted assignment shall be void and of no effect. Lender may assign, transfer, or endorse
its rights hereunder and under the other Loan Documents without prior notice to Borrower, and all of such rights
shall inure to the benefit of Lender’s successors and assigns.

any  disputes  arising  out  of  or  in  connection  with  this  Agreement  and  the  other  Loan  Documents  (including  a
dispute regarding the existence, validity or termination of this Agreement or the consequences of its nullity) and,
for such purposes, each of the parties hereto irrevocably submits to the exclusive jurisdiction of such courts. This
Section is for the benefit of the Lender only. As a result, the Lender may take proceedings relating to a dispute in
any other courts with jurisdiction. To the extent allowed by law, the Lender may take concurrent proceedings in
any number of jurisdictions.

10.10      Professional  Fees.  Borrower  promises  to  pay  Lender’s  documented  out-of-pocket  fees  and

foreclosure,  or  other  action  related  to  Borrower,  the  Collateral,  the  Loan  Documents,  including  representing
Lender in any adversary proceeding or contested matter commenced or continued by or on behalf of Borrower’s
estate, and any appeal or review thereof.

10.11   Confidentiality. Lender acknowledges that all financial statements provided to Lender by Borrower
and certain items of Collateral and information provided to Lender by Borrower are confidential and proprietary
information of Borrower, if and to the extent such information either (x) is marked as confidential by Borrower at
the  time  of  disclosure,  or  (y)  should  reasonably  be  understood  to  be  confidential  (the  “Confidential
Information”).  Accordingly,  Lender  agrees  that  any  Confidential  Information  it  may  obtain  in  the  course  of
acquiring,  administering,  or  perfecting  Lender’s  security  interest  in  the  Collateral  shall  not  be  disclosed  to  any
other  person  or  entity  in  any  manner  whatsoever,  in  whole  or  in  part,  without  the  prior  written  consent  of
Borrower,  except  that  Lender  may  disclose  any  such  information:  (a)  to  its  own  directors,  officers,  employees,
accountants, counsel and other professional advisors and to its affiliates if Lender in its sole discretion determines
that  any  such  party  should  have  access  to  such  information  in  connection  with  such  party’s  responsibilities  in
connection with the Loan or this Agreement and, provided that such recipient of such Confidential Information
either  (i)  agrees  to  be  bound  by  the  confidentiality  provisions  of  this  paragraph  or  (ii)  is  otherwise  subject  to
confidentiality restrictions that reasonably protect against the disclosure of Confidential Information; (b) if such
information is generally available to the public; (c) if required or appropriate in any report, statement or testimony
submitted to any governmental authority having or claiming to have jurisdiction over Lender; (d) if required or
appropriate in response to any summons or subpoena or in connection with any litigation, to the extent permitted
or deemed advisable by Lender’s counsel; (e) to comply with any legal requirement or law applicable to Lender;
(f)  to  the  extent  reasonably  necessary  in  connection  with  the  exercise  of  any  right  or  remedy  under  any  Loan
Document,  including  Lender’s  sale,  lease,  or  other  disposition  of  Collateral  after  the  occurrence  and  during  the
continuance of an Event of Default; (g) to any participant or assignee of Lender or any prospective participant or
assignee; provided, that such participant or assignee or prospective participant or assignee agrees in writing to be
bound by this Section prior to disclosure; or (h) otherwise with the prior consent of Borrower; provided, that any
disclosure made in violation of this Agreement shall not affect the obligations of Borrower or any of its affiliates
or any guarantor under this Agreement or the other Loan Documents.

10.12   Assignment of Rights. Borrower acknowledges and understands that Lender may sell and assign all
or part of its interest hereunder and under the Loan Documents to any person or entity (an “Assignee”). After such
assignment the term “Lender” as used in the Loan Documents shall mean and include such Assignee, and such
Assignee shall be vested with all rights, powers and remedies of Lender hereunder with respect to the interest so
assigned;  but  with  respect  to  any  such  interest  not  so  transferred,  Lender  shall  retain  all  rights,  powers  and
remedies hereby given. No such assignment by Lender shall relieve Borrower of any of its obligations hereunder.
Lender

35

agrees that in the event of any transfer by it of the Note(s) (if any), it will endorse thereon a notation as to the
portion of the principal of the Note(s), which shall have been paid at the time of such transfer and as to the date to
which interest shall have been last paid thereon.

10.13      Revival  of  Secured  Obligations.  This  Agreement  and  the  Loan  Documents  shall  remain  in  full
force  and  effect  and  continue  to  be  effective  if  any  petition  is  filed  by  or  against  Borrower  for  liquidation  or
reorganization, if Borrower becomes insolvent or makes an assignment for the benefit of creditors, if a receiver or
trustee is appointed for all or any significant part of Borrower’s assets, or if any payment or transfer of Collateral
is  recovered  from  Lender.  The  Loan  Documents  and  the  Secured  Obligations  and  Collateral  security  shall
continue  to  be  effective,  or  shall  be  revived  or  reinstated,  as  the  case  may  be,  if  at  any  time  payment  and
performance of the Secured Obligations or any transfer of Collateral to Lender, or any part thereof is rescinded,
avoided  or  avoidable,  reduced  in  amount,  or  must  otherwise  be  restored  or  returned  by,  or  is  recovered  from,
Lender  or  by  any  obligee  of  the  Secured  Obligations,  whether  as  a  “voidable  preference,”  “fraudulent
conveyance,” or otherwise, all as though such payment, performance, or transfer of Collateral had not been made.
In the event that any payment, or any part thereof, is rescinded, reduced, avoided, avoidable, restored, returned, or
recovered,  the  Loan  Documents  and  the  Secured  Obligations  shall  be  deemed,  without  any  further  action  or
documentation, to have been revived and reinstated except to the extent of the full, final, and indefeasible payment
to Lender in Cash.

10.14   Counterparts. This Agreement and any amendments, waivers, consents or supplements hereto may
be executed in any number of counterparts, and by different parties hereto in separate counterparts, each of which
when so delivered shall be deemed an original, but all of which counterparts shall constitute but one and the same
instrument.

10.15   Publicity.

(a)    Borrower consents to the publication and use by Lender and any of its member businesses and
affiliates of (i) Borrower’s name (including a brief description of the relationship between Borrower and Lender)
and logo for use on Lender’s website and as required for the purposes of filings with or reports to governmental
authorities required by law, and (ii) after review and approval by Borrower (a) Borrower’s name and a hyperlink

Materials”); (b) the names of officers of Borrower in the Lender Publicity Materials; and (c) Borrower’s name,
trademarks or servicemarks in any news release concerning Lender.

(b)          Neither  Borrower  nor  any  of  its  member  businesses  and  affiliates  shall,  without  Lender’s
consent, publicize or use, for any purpose other than filings with or reports to governmental authorities required
by law and the rules of any applicable securities commission or securities exchange, (i) Lender’s name (including
a  brief  description  of  the  relationship  between  Borrower  and  Lender),  logo  or  hyperlink  to  Lender’s  web  site,
separately or together, in written and oral presentations, advertising, promotional and marketing materials, client
lists, public relations materials or on its web site (together, the “Borrower Publicity Materials”); (ii) the names
of officers of Lender in the Borrower Publicity Materials; and (iii) Lender’s name, trademarks, servicemarks in

10.16    Existing Loan and Security Agreement Amended and Restated. Upon satisfaction of the conditions
precedent to the effectiveness of this Agreement, (a) this Agreement shall amend and restate the Existing Loan
and Security Agreement in its entirety (except to the extent that definitions from the Existing Loan and Security
Agreement  are  incorporated  herein  by  reference)  and  (b)  the  rights  and  obligations  of  the  parties  under  the
Existing Loan and Security Agreement shall be subsumed within, and be governed by, this Agreement; provided,
however, that the Borrower hereby agrees that all Secured Obligations of the Borrower under, and as defined in,
the  Existing  Loan  and  Security  Agreement  and  the  other  Loan  Documents  shall  remain  outstanding,  shall
constitute continuing Secured Obligations secured by the Collateral, and this Agreement shall not be deemed to
evidence or result in a novation or repayment and re-borrowing of such obligations and other liabilities. Borrower
hereby acknowledges and reaffirms each and every Loan Document entered into in connection with the Existing
Loan and Security Agreement and acknowledges that each such Loan Document remains in full force and effect
and enforceable against Borrower in accordance with its respective terms after giving effect to the execution and
delivery of this Agreement without further action by Lender, Borrower or any other Person. All reference to the
“Loan  and  Security  Agreement”  in  each  such  Loan  Document  shall  be  deemed  to  be  a  reference  to  this
Agreement.

10.17    Agency. Lender hereby irrevocably appoints HERCULES CAPITAL, INC. to act on its behalf as
agent hereunder and under the other Loan Documents and authorizes the agent to take such actions on its behalf
and  to  exercise  such  powers  as  are  delegated  to  the  agent  by  the  terms  hereof  or  thereof,  together  with  such
actions and powers as are reasonably incidental thereto.

RECITALS

A.                Subsidiary’s  Affiliates,  (i)  UNIQURE  BIOPHARMA  B.V.,  and  UNIQURE,  INC.,  (hereinafter
collectively referred to as “Borrower”) have, among others, entered into that certain Third Amended and Restated
Loan and Security Agreement dated December 15, 2021, with the lenders party thereto, as such agreement may be

therewith;

B.                  Subsidiary  acknowledges  and  agrees  that  it  will  benefit  both  directly  and  indirectly  from
Borrower’s  execution  of  the  Loan  Agreement  and  the  other  agreements  executed  and  delivered  in  connection

PREMISES AND APPURTENANT RIGHTS

2.1

Lease of Premises. Landlord hereby leases to Tenant and Tenant hereby leases from Landlord the Premises

for the Term and upon the terms and conditions hereinafter set forth.

2.2

Appurtenant Rights and Reservations

(a)

Tenant shall have, as appurtenant to the Premises, the non-exclusive right to use, and permit its

invitees to use in common with Landlord and others, (i) public or common lobbies, hallways, stairways, elevators and
common walkways necessary for access to the Building and the Premises, and if the portion of the Premises on any floor
includes less than the entire floor, the common toilets, corridors and elevator lobby of such floor; and (ii) the access roads,
driveways, parking areas, loading areas, pedestrian sidewalks, landscaped areas, trash enclosures and other areas or facilities,
if any, which are located in or on the Property and designated by Landlord from time to time for the non-exclusive use of
tenants and other occupants of the Property (the “Common Facilities”); but such rights shall always be subject to
reasonable rules and regulations from time to time established by Landlord pursuant to Section 15.6 (the “Rules and
Regulations”) and to the right of Landlord to designate and change from time to time such areas and facilities so to be used 
in accordance with Section 15.18 of this Lease. Notwithstanding anything to the contrary herein or in the Lease contained, 
Landlord has no obligation to allow any particular telecommunication service provider to have access to the Building or to 
the Premises. If Landlord permits such access, Landlord may condition such access upon the payment to Landlord by the 
service provider of reasonable fees assessed by Landlord in its sole discretion. Subject to the execution and delivery of a 
commercially reasonable access agreement between Landlord and Lumen that is acceptable to  Landlord, Landlord hereby 
approves Lumen as Tenant’s telecommunication service provider.

6

(b)

Excepted and excluded from the Premises and the Common Facilities are the floor slab, demising
walls and perimeter walls and exterior windows (except the inner surfaces of each thereof), and any space in the Premises
used for common shafts, stacks, pipes, conduits, fan rooms, ducts, electric or other utilities, sinks or other Building facilities,
but the entry doors (and related glass and finish work) to the Premises are a part thereof. Landlord shall have the right to
place in the Premises (but in such manner as to reduce to a minimum interference with Tenant’s use of the Premises) interior
storm windows, sun control devices, utility lines, equipment, stacks, pipes, conduits, ducts and the like, provided that any
such utility lines, equipment, stacks, pipes, conduits, ducts or the like, are located within the walls, below floors, and to the
exterior of interior walls. In the event that Tenant shall install any hung ceilings or walls in the Premises, Tenant shall install
and maintain, as Landlord may reasonably require, proper access panels therein to afford access to any facilities above the
ceiling or within or behind the walls. Tenant shall be entitled to install any such ceilings or walls only in compliance with the
other terms and conditions of this Lease. Except in connection with the installation of Alterations approved by Landlord
hereunder, Tenant shall have no right to access and use the fan rooms, janitorial, electrical, telephone and
telecommunications closets, conduits, risers, plenum spaces and other service areas of the Building without the prior written
consent of Landlord, which consent shall not be unreasonably withheld, conditioned, or delayed.

(c)

Tenant shall have the right, on an unreserved, non-exclusive basis, to park in the areas on the

Property (the “Parking Areas”), in common with other tenants of the Building upon such terms and conditions as may be
established by Landlord from time to time during the Term of this Lease. Tenant agrees not to overburden the Parking Areas
and agrees to cooperate with Landlord and other tenants in use of the Parking Areas. For purposes of determining whether
Tenant is overburdening the Parking Areas, Tenant shall be deemed to have a parking allocation of 46 parking spaces (which
is based on a ratio of 3.4 parking spaces for each one thousand square feet of Premises Rentable Area) and shall have the
right to park in such allocated parking spaces regardless of how the remaining parking spaces are allocated to other tenants
of the Building. Subject to such allocation, Landlord reserves the right in its sole, but reasonable, discretion to determine
whether the Parking Areas are becoming overburdened. Landlord shall have the absolute right (i) to allocate and assign
parking spaces among some or all of the tenants of the Building (and Tenant shall comply with any such parking
assignments), (ii) to reconfigure, maintain, repair and replace the paving in the Parking Areas, and/or (iii) to modify the
existing ingress to and egress from the Parking Areas as Landlord shall deem appropriate, as long as (x) access to such
Parking Areas is maintained after any such modification is completed and (y) Tenant at all times after any such modification,
reconfiguring, maintenance, repairs or paving replacement, has reasonable access to the parking to which it is entitled
hereunder, it being acknowledged by Tenant that Tenant’s parking spaces may be temporarily reduced during the period in
which Landlord is performing any work in connection with the foregoing. Landlord may delegate its responsibilities
hereunder to a parking operator in which case such parking operator shall have all the rights attributed hereby to Landlord.
The parking rights allocated to Tenant pursuant to this Lease are provided to Tenant solely for use by Tenant’s own
personnel and invitees and such rights may not be transferred, assigned, subleased or otherwise alienated by Tenant without
Landlord’s prior approval, other than to a Transferee in connection with a Transfer permitted without Landlord’s consent
under Section 6.1(b) or to a Transferee to whom Landlord consents pursuant to Section 6.1(a). The parking spaces initially
will not be separately identified; however Landlord reserves the right to separately identify by

7

signs or other markings the area or parking spaces to which Tenant’s parking rights relate . Landlord shall have no obligation
to monitor the use of the Parking Areas, nor shall Landlord be responsible for any loss or damage to any vehicle or other
property or for any injury to any person. Tenant shall comply with all reasonable rules and regulations which may be
adopted by Landlord from time to time with respect to parking and/or the Parking Areas. In the event Landlord elects, or is
required by any Law, to limit or control parking, whether by validation of parking tickets or any other method of assessment,
Tenant agrees to participate in such validation or assessment program under such reasonable rules and regulations as are
from time to time established by Landlord.

(d)

The designation or use from time-to-time of portions of the Property exterior to the Premises as
Common Facilities shall not restrict Landlord’s use of such areas for buildings, structures and/or for retail or such other
purposes in connection with and consistent with the operations of the Property as Landlord shall determine, Landlord hereby
reserving the unrestricted right to build, add to, subtract from, lease, license, relocate and/or otherwise use (temporarily
and/or permanently), any buildings, kiosks, other structures, parking areas, roadways or other areas or facilities anywhere
upon the Property for such other purposes as Landlord shall determine, provided that such actions do not materially
adversely affect Tenant’s quite use and enjoyment of the Premises or increase its obligations hereunder.

(e)

Landlord shall install, at Landlord’s expense, building-standard suite entry signage; provided, that

Tenant may install, at Tenant’s expense, non-building-standard signs or lettering on the entry doors to the Premises provided
such signs are approved by Landlord in writing in advance and otherwise conform to sign standards for the Building adopted
by Landlord in its sole discretion and Tenant has submitted to Landlord a plan or sketch in reasonable detail (showing,
without limitation, size, color, location, materials and method of affixation) of the sign to be placed on such entry doors.
Except for the foregoing signage, Tenant will not place on the exterior of the Premises (including both interior and exterior
surfaces of doors and interior surfaces of windows) or on any part of the Building outside the Premises, any sign, symbol,
advertisement or the like visible to public view outside of the Premises. If and only so long as Landlord maintains a tenant
directory in the main lobby of the Building, Landlord shall cause Tenant’s name to be listed on such tenant directory;
provided, however, that any changes or replacements of such lobby listing after the initial installation shall be at Tenant’s
expense.

(f)

Landlord hereby covenants to provide to Tenant, and Tenant will have the non-exclusive right of

access to and use of (such right of access and use being at no cost to Tenant), the portion of the surface area of the roof of the
Building shown on Exhibit B attached hereto (the “Rooftop Area”) to install and service (at Tenant’s sole cost and expense)
a reasonable amount of telecommunication equipment, dedicated HVAC, stand-by generator (a “Generator”), and other
equipment (such use, the “Roof Use;” such equipment, the “Rooftop Equipment”); provided that Landlord shall have the
right to grant similar access and use rights to other tenants. In exercising Tenant’s right to use the Rooftop Area: (i) Tenant
must first notify Landlord and obtain Landlord’s consent to the specific Rooftop Equipment and manner of installation
(which consent shall not be unreasonably withheld, conditioned or delayed (provided, that Landlord may condition its
approval on Tenant using Landlord’s preferred contractors)); (ii) Tenant shall (x) be responsible for obtaining all permits,
approvals, licenses

8

and the like, necessary to install any such Rooftop Equipment and for the Roof Use (Landlord agreeing to cooperate in
connection with the same, at no cost or liability to Landlord, and without being required to attend any public hearings in
connection with the same) and (y) comply with all Laws, with any covenants, conditions and restrictions of record
applicable to the Building (including, without limitation, any applicable MassPort requirements, including the MassPort
avigation easement), and with all requirements of any board of fire insurance underwriters or similar body and shall obtain
any additional insurance coverage reasonably required by Landlord or otherwise required by governmental authorities in
connection with Tenant’s Roof Use; (iii) the Roof Use and installation of the Rooftop Equipment shall not void any roof or
other warranty applicable to the Building, and Landlord may require that Tenant obtain written confirmation from the roof or
other warrantor that the Roof Use and installation of the Rooftop Equipment does not void any such warranty; (iv) such
Rooftop Equipment shall be located and screened in a manner mutually acceptable to Landlord and Tenant in their
reasonable discretion; (v) such Rooftop Equipment (other than any Rooftop Equipment installed as part of Landlord’s Work,
if any) shall be removed by Tenant upon surrender of the Premises (including repair of any damage caused by such removal)
(vi) Tenant shall pay, annually in advance, to Landlord, any increases in Landlord’s insurance directly attributable to
Tenant’s particular Roof Use as evidenced by Landlord in writing; (vii) Landlord makes no representations, warranties or
promises regarding the suitability of the Building’s roof for the Roof Use, and Tenant accepts the roof in its “as is” condition
(subject to Landlord’s maintenance and repair obligations set forth elsewhere in this Lease); (viii) the Roof Use and the
Rooftop Equipment shall not create any hazardous condition or interfere with or impair the operation of the Building
Systems or utilities or other systems or facilities for the Building (including communications equipment installed by
Landlord or any other Building tenants) installed prior to such Rooftop Equipment, and shall not directly or indirectly
interfere with, delay, restrict or impose any expense, work or obligation upon Landlord in the use or operation of the
Building; (ix) the installation, repair, replacement, servicing and maintenance of the Rooftop Equipment shall be at Tenant’s
sole cost and expense, including the cost of repairing all damage to the Buildings and any personal injury and/or property
damage to the Building to the extent attributable to the installation, inspection, adjustment, maintenance, removal or
replacement of any of Tenant’s Rooftop Equipment; (x) the Tenant’s installation of any Rooftop Equipment in the Rooftop
Area, or its operation following the installation thereof, shall not interfere with the permitted uses by other tenants or
occupants of their premises or of any antennae, communication dishes, or other improvements installed by such tenants or
occupants in compliance with applicable Laws, and (xi) the Roof Use shall be solely in the ordinary course of Tenant’s
business operations (and Tenant may not sublease, license or otherwise permit third parties to establish communications
transmission facilities as part of Tenant’s Roof Use except as a right appurtenant to their subletting of the Premises or
assumption of this Lease). Notwithstanding the foregoing, if Landlord reasonably determines that the Tenant’s Rooftop
Equipment is interfering with the equipment of other tenants of the Building placed on the roof in compliance with the terms
of such tenant’s lease and Tenant’s rights hereunder, Landlord shall notify Tenant and shall afford Tenant not less than five
(5) Business Days to cure such interference (or such shorter period as is reasonable under the circumstances relating to the
impact of such interference on the equipment of such other tenants). Tenant shall not install any equipment or other property
on the roof pursuant to this Section 2.2(f) without Landlord’s prior reasonable approval of the manner of such installation
and detailed plans and specifications for such installation and all such installations shall be subject to

9

the terms of this Lease applicable to Alterations. Any electric current necessary to operate the Tenant’s Rooftop Equipment
shall be obtained by Tenant from the public utility furnishing electricity to the Premises (or derived from the same separately
metered or separately check-metered service in the Premises) and Landlord shall have no obligation to furnish any electric
current (or any other utilities) in connection therewith. Notwithstanding anything in this Section 2.2(f) to the contrary,
Landlord shall have the right, at any time upon thirty (30) days’ prior written notice to Tenant indicating the relocation
location and requirement, to require Tenant to relocate any of its Rooftop Equipment to such alternative rooftop location as
is reasonably designated by Landlord in such notice; provided that no such relocation shall unreasonably interrupt Tenant’s
operations in the Premises and any such relocation shall be scheduled in a manner reasonably necessary to minimize any
interference with Tenant’s occupancy of the Premises or business therein. Such relocation shall be at Landlord’s sole cost
and expense and shall be to functionally equivalent areas of the roof. If Tenant fails to comply with the terms of this Section
2.2(f) regarding such Roof Use within applicable notice and cure periods, Landlord shall have the right to require Tenant to
remove the Tenant’s Rooftop Equipment that is not in compliance with Tenant’s Roof Use rights set forth in this Section
2.2(f), in which event such removal shall be at Tenant’s sole cost and expense.

(g)

Tenant shall be allowed to utilize up to Tenant’s Proportionate Share of space in the chemical

storage room on the first floor of the Building (the “Chemical Storage Room”). If the use of Hazardous Materials by Tenant
requires fire control areas or chemical storage areas in excess of Tenant’s Proportionate Share, then Tenant shall, at its sole
cost and expense and upon Landlord’s written request, establish and maintain a separate area of the Premises in compliance
with applicable Laws and the Rules and Regulations. Notwithstanding anything in this Lease to the contrary, Landlord shall
not have and expressly disclaims any liability (unless arising from Landlord's negligence or willful misconduct) related to
Tenant’s or other tenants’ use or disposal of Hazardous Materials within the Chemical Storage Room, it being acknowledged
by Tenant that Tenant and other tenants are best suited to evaluate the safety and efficacy of its Hazardous Materials usage
and procedures in the Premises and in the Chemical Storage Room.

(h)

Tenant may operate an animal holding facility within a specific portion of the Premises that is

approved in advance in writing by Landlord, such approval not to be unreasonably withheld, conditioned or delayed. The
animal holding facility shall be constructed in accordance with all applicable Laws and in accordance with plans and
specifications approved in writing by Landlord and shall include a vacuum-enabled disposal facility for bedding waste and
any other noxious wastes; provided, that to the extent applicable, if Landlord constructs the animal holding facility as part of
a Change (as defined in the Work Letter), Landlord shall construct the same in accordance with all applicable Laws. The
animal holding facility shall be used for biopharmaceutical research and development and the handling and testing of small
rodents (collectively, the “Permitted Animals”). If Tenant proposes to use any animals other than the Permitted Animals in
its operations, it shall first obtain the prior written consent of Landlord. Animal testing, solely of Permitted Animals, shall be
permitted subject to the following: (i) all testing shall be conducted in strict compliance with all applicable Laws (including
without limitation, Environmental Laws), best scientific and medical practices and in a manner consistent with the highest
standards of the industry; (ii) all animal carcasses, any part thereof or any waste product related thereto (including, without
limitation, any cages or other

10

containers of the Permitted Animals), shall be disposed of, at Tenant’s sole cost and expense, by a qualified and licensed
waste disposal company engaged by Tenant, and not in any common disposal receptacles at the Property, and in strict
compliance with all applicable Laws (including without limitation, Environmental Laws), best scientific and medical
practices and in a manner consistent with the highest standards of the industry; (iii) no odors, noises or any similar nuisance
shall be permitted to emanate from or permeate outside the animal holding facility; and (iv) Tenant’s use of the animal
holding facility shall not interfere with the quiet use and enjoyment by other tenants or occupants of the Building or their
respective premises in the Building. Tenant shall procure and deliver to Landlord copies of all necessary permits and
approvals necessary for the use and operation of the animal holding facility before allowing any actual Permitted Animals
into the Premises and shall maintain such permits and approvals during the Term and deliver to Landlord copies thereof from
time-to-time upon Landlord’s written request. All deliveries of the Permitted Animals to the Premises shall be made through
a pathway to the Premises that avoids the lobby of the Building (unless the deliveries are made between the hours of 7:00
p.m. and 7:00 a.m.) and shall not interfere with, damage or adversely affect any items being delivered or any deliveries being
made to Landlord or any other tenants or occupants. Prior to the expiration or earlier termination of the Lease, Tenant shall
remove the animal holding facility and all contents of the animal holding facility, including without limitation all animals,
from the Premises and shall repair any damage caused by such removal at its sole cost and expense.

2.3

Option to Extend.

(a)

Provided that, at the time of such exercise, (i) this Lease is in full force and effect, and (ii) Tenant

shall not be in default of any of its obligations hereunder (either at the time of exercise or at the commencement of the
Extended Term) (provided that Tenant may retain any right hereunder by curing such default within the applicable cure
period), and (iii) Tenant shall be in occupancy of the entire Premises for the conduct of its business (other than to the extent
occupancy is not possible because of Force Majeure or on-going Alterations) and shall not have assigned this Lease or sublet
the Premises, other than any assignment or sublease permitted under Section 6.1(b) without Landlord’s written consent (any
of which conditions described in clauses (i), (ii), and (iii) may be waived by Landlord at any time in Landlord’s sole
discretion), Tenant shall have the right and option to extend the Term of this Lease with respect to the entire Premises for one
(1) extended term (the “Extended Term”) of five (5) years, by giving written notice to Landlord not later than twelve (12)
months prior to the expiration date of the initial Term. The effective giving of such notice of extension by Tenant shall
automatically extend the Term of this Lease for the Extended Term, and no instrument of renewal or extension need be
executed. In the event that Tenant fails timely to give such notice to Landlord, this Lease shall automatically terminate at the
end of the initial Term, and Tenant shall have no further option to extend the Term of this Lease. The Extended Term shall
commence on the day immediately succeeding the expiration date of the initial Term, and shall end on the day immediately
preceding the fifth (5th) anniversary of the first day of the Extended Term. The Extended Term shall be on all the terms and
conditions of this Lease, except: (x) during the Extended Term, Tenant shall have no further option to extend the Term, (y)
the Basic Rent for the Extended Term shall be the Fair Market Rental Value of the Premises as of the commencement of the
Extended Term, taking into account all relevant factors, determined pursuant to Section 2.3(b) below, and (z) Landlord shall
not be required to furnish any materials

11

or perform any work to prepare the Premises for Tenant’s occupancy during the Extended Term and Landlord shall not be
required to provide any work allowance or reimburse Tenant for any alterations made or to be made by Tenant, or to grant
Tenant any rent concession.

(b)

Promptly after receiving Tenant’s notice extending the Term of this Lease pursuant to Section 2.3(a)

above, Landlord shall provide Tenant with Landlord’s good faith estimate of the Fair Market Rental Value (as defined in
Section 2.3(c) below) of the Premises for the upcoming Extended Term provided that in no event shall Landlord be required 
to deliver such estimate sooner than eleven (11) months prior to the expiration of the Term then in effect. If Tenant is 
unwilling to accept Landlord’s estimate of the Fair Market Rental Value as set forth in Landlord’s notice referred to above, 
and the parties are unable to reach agreement thereon within thirty (30) days after the delivery of such notice by Landlord, 
then either party may submit the determination of the Fair Market Rental Value of the Premises to arbitration by giving 
notice to the other party naming the initiating party’s arbitrator within ten (10) days after the expiration of such thirty (30)-
day period; provided, that if either party fails to deliver such notice electing to submit the determination of the Fair Market 
Rental Value to arbitration within such ten (10) day period, then Landlord’s initial determination of Fair Market Rental Value 
shall be binding on the parties. Within fifteen (15) days after receiving a notice of initiation of arbitration, the responding 
party shall appoint its own arbitrator by notifying the initiating party of the responding party’s arbitrator. If the second 
arbitrator shall not have been so appointed within such fifteen (15) day period, the Fair Market Rental Value of the Premises 
shall be determined by the initiating party’s arbitrator. If the second arbitrator shall have been so appointed, the two 
arbitrators thus appointed shall, within fifteen (15) days after the responding party’s notice of appointment of the second 
arbitrator, appoint a third arbitrator. If the two initial arbitrators are unable timely to agree on the third arbitrator, then either 
may, on behalf of both, request such appointment by the Boston office of JAMS, Inc., or its successor, or, on its failure, 
refusal or inability to act, by a court of competent jurisdiction. The Fair Market Rental Value of the Premises for the 
Extended Term shall be determined by the method commonly known as  Baseball Arbitration, whereby Landlord’s selected 
arbitrator and Tenant’s selected arbitrator shall each set forth its respective determination of the Fair Market Rental Value of 
the Premises, and the third arbitrator must select one or the other (it being understood that the third arbitrator shall be 
expressly prohibited from selecting a compromise figure). Landlord’s selected arbitrator and Tenant’s selected arbitrator 
shall deliver their determinations of the Fair Market Rental Value of the Premises to the third arbitrator within five (5) 
Business Days of the appointment of the third arbitrator and the third arbitrator shall render his or her decision within ten 
(10) days after receipt of both of the other two determinations of the Fair Market Rental Value of the Premises. The third 
arbitrator’s decision shall be binding on both Landlord and Tenant. All arbitrators shall be commercial real estate brokers 
who are independent from the parties and who have had at least ten (10) years’ experience in leases of comparable premises 
in comparable laboratory buildings in the central 128 area of suburban Boston. Each party shall pay the fees of its own 
arbitrator, and the fees of the third arbitrator shall be shared equally by the parties. In the event Tenant initiates the aforesaid 
arbitration process and as of the commencement of the Extended Term the amount of the Basic Rent for the Extended Term 
has not been determined, Tenant shall pay the amount of Basic Rent in effect during the last month of the initial Term plus 
Additional Rent and when the determination has actually been made, an appropriate retroactive adjustment shall be made as 
of the commencement of the Extended Term if necessary. In the event that such determination shall result in an overpayment 
by Tenant of any Basic Rent, such

12

overpayment  shall  be  paid  by  Landlord  to  Tenant  promptly  after  such  determination  has  been  made,  and  if  such
determination shall result in an underpayment by Tenant of any Basic Rent, Tenant shall pay any such amounts to Landlord
promptly following such determination.

(c)

As used in this Lease, the term “Fair Market Rental Value” shall mean the fixed rents being that

landlords of comparable first class laboratory buildings in the central 128 area of suburban Boston have agreed to accept,
and sophisticated nonaffiliated tenants of comparable buildings have agreed to pay, in current arms-length, nonequity (i.e.,
not being offered equity in the building), transactions for comparable space (in terms of condition, improvements, floor
location and floor height) of a comparable size, for a term equal to the applicable Extended Term and taking into account all
other relevant factors, including, to the extent applicable, any tenant improvement allowances, brokerage fees and free rent
periods; provided, however, that in no event will the Fair Market Rental Value be less than the Basic Rent in effect during
the last month of the initial Term.

3.1

Payment.

ARTICLE 3
BASIC RENT

(a)

Tenant agrees to pay the Basic Rent and Additional Rent to Landlord, or as directed by Landlord,

commencing on the Commencement Date, without offset, abatement, deduction or demand, except as expressly set forth in
this Lease. Notwithstanding the foregoing, the first monthly installment of Basic Rent shall be paid to Landlord upon
execution and delivery of this Lease by Tenant. Basic Rent shall be payable in equal monthly installments, in advance, on
the first day of each and every calendar month during the Term of this Lease, to Landlord at Landlord’s Notice Address or at
such other place as Landlord shall from time to time designate by notice, in lawful money of the United States. In the event
that any installment of Basic Rent or any payment of Additional Rent is not paid when due, Tenant shall pay, in addition to
any charges under Section 14.4, at Landlord’s request an administrative fee equal to 5% of the overdue payment.
Notwithstanding the foregoing, Tenant shall not be obligated to pay such late charge for the first such late payment in any
twelve (12) month period, provided that such payment is made within five (5) Business Days after notice from Landlord that
such amount was not paid when due. In addition to the foregoing, if payment of Rent or other charges due under this Lease
are not paid within ten (10) days after the date due, such past due amount shall bear interest from the date due until paid at a
rate equal to the lesser of (i) a rate equal to 3% plus the prime rate published from time to time in The Wall Street Journal or
its successor publication and (ii) the highest rate permitted to be charged by applicable Law (the “Default Interest Rate”). 
Landlord and Tenant agree that all amounts due from Tenant under or in respect of this  Lease, whether labeled Basic Rent, 
Escalation Charges, Additional Rent or otherwise, shall be considered as rental reserved under this Lease for all purposes, 
including without limitation regulations promulgated pursuant to the Bankruptcy Code, and including further without 
limitation Section 502(b) thereof.

(b)

Basic Rent for any partial month shall be pro-rated on a daily basis, and if the first day on which

Tenant must pay Basic Rent shall be other than the first day of a calendar

13

month, the first payment which Tenant shall make to Landlord shall be equal to a proportionate part of the monthly
installment of Basic Rent for the partial month from the first day on which Tenant must pay Basic Rent to the last day of the
month in which such day occurs, plus the installment of Basic Rent for the succeeding calendar month.

ARTICLE 4
CONDITION OF PREMISES

4.1

Condition of Premises; Initial Improvements. Except for Landlord’s Work, if any, to be performed by

Landlord in accordance with the provisions of Exhibit C or as otherwise expressly provided in this Lease, the Premises are 
being leased in their present condition, AS IS,  WITHOUT REPRESENTATION OR WARRANTY by Landlord. Except for 
Landlord’s Work, if any, Landlord shall have no obligation to perform any alterations or to make any improvements to the 
Premises to prepare them for Tenant’s occupancy. Tenant acknowledges that Tenant has inspected the Premises and Common 
Facilities and has found the same satisfactory.

ARTICLE 5
USE OF PREMISES

5.1

Permitted Use. Tenant agrees that the Premises shall be used and occupied by Tenant only for the Permitted

Use and for no other use without Landlord’s express written consent. Tenant shall not perform any act or carry on any
practice which may injure the Premises, or any other part of the Building, or cause any offensive odors or loud noise or
constitute a nuisance or a menace to any other tenant or tenants or other persons in the Building.

5.2

Installations and Alterations by Tenant.

(a)

Tenant shall make no alterations, additions (including, for the purposes hereof, wall-to-wall
carpeting), or improvements (collectively, “Alterations”) in or to the Premises (including any Alterations, other than
Landlord’s Work, necessary for Tenant’s initial occupancy of the Premises) or any Base Building Systems serving the
Premises without Landlord’s prior written consent, which consent shall not be unreasonably withheld or delayed with respect
to non-structural Alterations that do not affect any portion of the Base Building or the Base Building Systems. Any
Alterations shall be in accordance with Landlord’s Rules and Regulations from time to time in effect and with plans and
specifications meeting the requirements set forth in such Rules and Regulations and approved in advance by Landlord, such
approval not to be unreasonably withheld, conditioned, or delayed. All Alterations shall (i) be performed in a good and
workmanlike manner using only new (except as shown in plans approved by Landlord) and only quality materials and in
compliance with all applicable Laws; (ii) be made at Tenant’s sole cost and expense; (iii) become part of the Premises and
the property of Landlord upon the expiration or earlier termination of the Term of this Lease unless Landlord otherwise
notifies Tenant such Alteration must be removed as provided in Section 5.2(e) below; (iv) be made by contractors and
subcontractors approved in advance by Landlord, such approval not to be unreasonably withheld, conditioned, or delayed;
and (v) be coordinated with any work

14

being performed by Landlord in such a manner as not to damage the Building or interfere with the management,
maintenance or operation of the Building. At Landlord’s request, Tenant shall, before its work is started, secure assurances
satisfactory to Landlord in its reasonable discretion protecting Landlord against claims arising out of the furnishing of labor
and materials for the Alterations where such Alterations exceed $250,000, in any one Lease Year, except to the extent
required by any Superior Mortgage. If any Alterations shall involve the removal of fixtures, equipment or other property in
the Premises which are not Tenant’s Removable Property, such fixtures, equipment or property shall be promptly replaced by
Tenant at its expense with new fixtures, equipment or property of like utility and of at least equal quality, except as shown on
plans for Alterations approved by Landlord. Tenant shall promptly reimburse Landlord for all reasonable out of pocket costs,
including attorneys’, architects’, engineers’, and consultants’ fees, incurred by Landlord in connection with any request from
Tenant pursuant to this Section 5.2. Tenant acknowledges and agrees that any review or approval by Landlord of any plans
and/or specifications with respect to any Alterations is solely for Landlord’s benefit, and without any representation or
warranty whatsoever to Tenant with respect to the adequacy, correctness or efficiency thereof or otherwise. Landlord shall
have the right to require that Tenant use Landlord’s designated structural contractor and architect for the Building for the
design and performance of any Alterations affecting the Structural Elements and/or that Tenant use Landlord’s designated
fire and life safety contractor and engineer for the Building to perform Tenant’s connection to the Building’s fire alarm
system or any Alterations that affect the fire alarm or fire/life safety systems in the Building.

(b)

All articles of personal property and all business and trade fixtures, furniture, moveable partitions,

freestanding cabinet work, machinery and equipment owned or installed by Tenant or any party claiming by, through or
under Tenant solely at its expense in the Premises (“Tenant’s Removable Property”) shall remain the property of Tenant
and may be removed by Tenant at any time prior to the expiration or earlier termination of the Term, provided that Tenant, at
its expense, shall repair any damage to the Building caused by such removal. Any provision of this Lease to the contrary
notwithstanding, Tenant shall be solely responsible for the ordering, delivery and installation of any telephone, telephone
switching, telephone and data cabling, and Tenant’s Removable Property to be installed by or on behalf of Tenant in the
Premises and for the removal of all telephone and data cabling and all other lines installed in the Building by or on behalf of
Tenant or anyone claiming by, through or under Tenant at the expiration or earlier termination of the Term of this Lease.

(c)

Notice is hereby given to contractors of Tenant that Landlord shall not be liable for any labor or

materials furnished or to be furnished to Tenant upon credit, and that no mechanic’s or other lien for any such labor or
materials shall attach to or affect the reversion or other estate or interest of Landlord in and to the Premises, the Building or
the Property. To the maximum extent permitted by law, before such time as any contractor commences to perform work on
behalf of Tenant, such contractor (and any subcontractors) shall furnish a written statement in the form of Attachment II to
Exhibit F acknowledging the provisions set forth in the prior clause. Tenant agrees to pay promptly when due the entire cost
of any work done on behalf of Tenant, its agents, employees or independent contractors, and not to cause or permit any liens
for labor or materials performed or furnished in connection therewith to attach to all or any part of the Property and promptly
to discharge or bond over any such liens which may so attach within 20 days following notice of the same (the parties
agreeing that the mere filing of a notice

15

of contract is not a lien for purposes of this Lease, unless a Superior Mortgagee requires the same to be bonded over or the
same is not released of record within thirty (30) days of the completion of the applicable work). If, notwithstanding the
foregoing, any lien is filed against all or any part of the Property for work claimed to have been done for, or materials
claimed to have been furnished to, Tenant or its agents, employees or independent contractors, Tenant, at its sole cost and
expense, shall cause such lien to be dissolved promptly after receipt of notice that such lien has been filed, by the payment
thereof or by the filing of a bond sufficient to accomplish the foregoing. If Tenant shall fail to discharge or bond over any
such lien within 20 days after notice of the same, Landlord may, at its option, discharge or bond over such lien and treat the
cost thereof (including reasonable attorneys’ fees incurred in connection therewith) as Additional Rent payable upon
demand, it being expressly agreed that such discharge or bonding over by Landlord shall not be deemed to waive or release
the Event of Default in not discharging or bonding over such lien. Tenant shall indemnify and hold Landlord harmless from
and against any and all expenses, liens, claims, liabilities and damages based on or arising, directly or indirectly, by reason
of the making of any alterations, additions or improvements by or on behalf of Tenant to the Premises under this Section,
which obligation shall survive the expiration or termination of this Lease.

(d)

In the course of any work being performed by Tenant (including, without limitation, the installation
or removal of any Tenant’s Removable Property), Tenant agrees to maintain labor harmony. As of the date hereof, there is no
requirement applicable to the Property requiring that Tenant use union labor with respect to any Alterations.

(e)

Landlord may, by written notice to Tenant prior to the expiration or earlier termination of the Term

of this Lease, require Tenant, at Tenant’s expense, to remove any Alterations in the Premises at the expiration or earlier
termination of the Term, to repair any damage to the Premises and Building caused by such removal and return the affected
portion of the Premises to a Building standard tenant improved condition as determined by Landlord. Notwithstanding the
foregoing, Tenant shall not be required to remove and/or restore at the expiration or earlier termination of the Term of this
Lease the Landlord’s Work to the extent constructed by Landlord pursuant to the Baseline Plans (as defined in the Work
Letter). If Tenant fails to complete such removal and/or to repair any damage caused by the removal of any Alterations in the
Premises, and return the affected portion of the Premises to a Building standard tenant improved condition as determined by
Landlord, then, without limiting Landlord’s other rights and remedies, at Landlord’s option, either (A) Tenant shall be
deemed to be holding over in the Premises and Rent shall continue to accrue in accordance with the terms of Article 12,
below, until such work shall be completed, or (B) Landlord may do so and may charge the cost thereof to Tenant.

5.3

Extra Hazardous Use. Tenant covenants and agrees that Tenant will not do or permit anything to be done in

or upon the Premises, or bring in anything or keep anything therein, which shall increase the rate of property or liability
insurance on the Premises or the Property above the standard rate applicable to Premises being occupied for the Permitted
Use. If the premium or rates payable with respect to any policy or policies of insurance carried by or on behalf of Landlord
with respect to the Property increases as a result of any act or activity on or use of the Premises during the Term or payment
by the insurer of any claim arising from any act or neglect of Tenant, its employees, agents, contractors or invitees, Tenant
shall pay such

16

increase, from time to time, within fifteen (15) days after demand therefor by Landlord, as Additional Rent.

5.4

Hazardous Materials.

(a)

Tenant shall not cause or permit any Hazardous Materials to be brought upon, kept or used in or
about the Premises, the Building or the Property in violation of applicable Laws (or that would require any type of zoning
relief) by Tenant or any of its employees, agents, contractors or invitees (collectively with Tenant, each a “Tenant Party”).
If (i) Tenant breaches such obligation, (ii) the presence of Hazardous Materials as a result of such a breach results in
contamination of the Property, any portion thereof, or any adjacent property, (iii) contamination of the Premises otherwise
occurs during the Term or any extension or renewal hereof or holding over hereunder other than on account of Hazardous
Materials existing at the Property prior to the Commencement Date (except to the extent exacerbated by any Tenant Party),
Hazardous Materials migrating to the Premises from elsewhere at the Property (except to the extent exacerbated by any
Tenant Party), or to the extent the same is caused by a Landlord Party (as defined below) (collectively, “Excluded
Matters”), or (iv) contamination of the Property occurs as a result of Hazardous Materials that are placed on or under or are
released into the Property by a Tenant Party, then Tenant shall indemnify, save, defend (at Landlord’s option and with
counsel reasonably acceptable to Landlord) and hold the Landlord Indemnitees harmless from and against any and all
demands, claims, liabilities, losses, costs, expenses, actions, causes of action, damages, suits or judgments, and all
reasonable expenses (including reasonable attorneys’ fees, charges and disbursements, regardless of whether the applicable
demand, claim, action, cause of action or suit is voluntarily withdrawn or dismissed) (“Claims”) of any kind or nature,
including (w) diminution in value of the Property or any portion thereof, (x) damages for the loss or restriction on use of
rentable or usable space or of any amenity of the Property, (y) damages arising from any adverse impact on marketing of
space at the Property or any portion thereof and (z) sums paid in settlement of Claims that arise during or after the Term as a
result of such breach or contamination. This indemnification by Tenant includes costs incurred in connection with any
investigation of site conditions or any clean-up, remedial, removal or restoration work required by any Governmental
Authority because of Hazardous Materials present in the air, soil or groundwater above, on, under or about the Property on
account of the foregoing. Without limiting the foregoing, if the presence of any Hazardous Materials in, on, under or about
the Property, any portion thereof or any adjacent property caused or permitted by any Tenant Party results in any
contamination of the Property, any portion thereof or any adjacent property, then Tenant shall promptly take all actions at its
sole cost and expense as are necessary to return the Property, any portion thereof or any adjacent property to its respective
condition existing prior to the time of such contamination; provided that Landlord’s written approval of such action shall
first be obtained (other than in the event of an emergency, in which case Tenant shall give Landlord telephonic notice
immediately upon such emergency event and shall provide Landlord with written notice within one (1) business day
thereafter), which approval Landlord shall not unreasonably withhold, conditioned or delayed; and provided, further, that it
shall be reasonable for Landlord to withhold its consent if such actions could have a material adverse long-term or short-
term effect on the Property, any portion thereof or any adjacent property. Tenant’s obligations under this Section shall not be
affected, reduced or limited by any limitation on the amount or type of damages, compensation or benefits

17

payable by or for Tenant under workers’ compensation acts, disability benefit acts, employee benefit acts or similar
legislation.

(b)

Landlord acknowledges that it is not the intent of this Article to prohibit Tenant from operating its
business for the Permitted Use. Tenant may operate its business according to the custom of Tenant’s industry so long as the
use or presence of Hazardous Materials is strictly and properly conducted in accordance with Applicable Laws. As a
material inducement to Landlord to allow Tenant to use Hazardous Materials in connection with its business, Tenant agrees
to deliver to Landlord, upon Landlord’s request from time to time as set forth below (i) a list identifying each type and
maximum quantity (which shall not exceed the maximum amounts identified in Exhibit H-1 with respect to the materials
described therein) of Hazardous Material to be present at the Premises and Chemical Storage Room that is subject to
regulation under any Environmental Laws, which list as of the date of this Lease is attached hereto as Exhibit H; (ii) a list of
any and all approvals or permits from governmental authorities required in connection with the presence of such Hazardous
Material at the Premises; and (iii) correct and complete copies of (x) notices of violations of applicable Laws related to
Hazardous Materials at the Premises and (y) plans relating to the installation of any storage tanks to be installed in, on, under
or about the Property (provided that installation of storage tanks shall only be permitted after Landlord has given Tenant its
written consent to do so, which consent Landlord may withhold in its sole and absolute discretion with respect to below
ground tanks) and closure plans or any other documents required by any and all Governmental Authorities for any storage
tanks installed in, on, under or about the Property for the closure of any such storage tanks (collectively, “Hazardous
Materials Documents”). Tenant shall not use or store Hazardous Materials that are not listed on Exhibit H or a subsequent
update thereto previously provided to Landlord by written notice; provided, that (x) as of the date hereof, Tenant has not
provided Exhibit H to Landlord, but Tenant shall provide such list to Landlord for Landlord’s review and approval within
thirty (30) days after the date hereof and upon such review and approval by Landlord, such list shall constitute Exhibit H for
all purposes of this Lease (provided, further that Landlord shall not withhold its consent to such list of Hazardous Materials
so long as the same are reasonably necessary for Tenant’s operations, the same are permitted to be used in the Premises
under all applicable Laws, the same do not require any zoning relief to be permitted to be used in the Premises and the same
do not exceed the maximum quantities for such Hazardous Materials or types of Hazardous Materials listed on Exhibit H-1
where applicable), and (y) in any event, Tenant shall not (under any circumstances) exceed the maximum quantities for such
Hazardous Materials or types of Hazardous Materials listed on Exhibit H-1 where applicable and shall not use, store or
dispose of such Hazardous Materials or types of Hazardous Materials listed on Exhibit H-1 where applicable in violation of
the limits set forth therein for closed or open use. Tenant shall deliver to Landlord updated Hazardous Materials Documents,
within fourteen (14) days after receipt of a written request therefor from Landlord, not more often than once per year, unless
there are any changes to the Hazardous Materials Documents or Tenant initiates any Alterations or changes its business, in
each case in a way that involves any material increase in the types or amounts of Hazardous Materials. For each type of
Hazardous Material listed, the Hazardous Materials Documents shall include (t) the chemical name, (u) the material state
(e.g., solid, liquid, gas or cryogen), (v) the concentration, (w) the maximum storage amount and storage condition (e.g., in
cabinets or not in cabinets), (x) the maximum use amount and use condition (e.g., open use or closed use), (y) the location
(e.g., room number or other identification) and (z) if known, the chemical abstract service number.

18

Notwithstanding anything in this Section to the contrary, Tenant shall not be required to provide Landlord with any
Hazardous Materials Documents containing information of a proprietary nature, which Hazardous Materials Documents, in
and of themselves, do not contain a reference to any Hazardous Materials or activities related to Hazardous Materials.
Landlord may, at Tenant’s expense (but not to exceed $1,000 on any one occasion), cause the Hazardous Materials
Documents to be reviewed by a person or firm qualified to analyze Hazardous Materials to confirm compliance with the
provisions of this Lease and with Applicable Laws. In the event that a review of the Hazardous Materials Documents
indicates non-compliance with this Lease or applicable Laws, Tenant shall, at its expense, diligently take steps to bring its
storage and use of Hazardous Materials into compliance and pay Landlord for the expense of any review identifying the
same. Notwithstanding (i) anything in this Lease to the contrary, or (ii) Landlord’s review into Tenant’s Hazardous Materials
Documents or use or disposal of hazardous materials, Landlord shall not have and expressly disclaims any liability related to
Tenant’s or other tenants’ use or disposal of Hazardous Materials; it being acknowledged by Tenant that Tenant is best suited
to evaluate the safety and efficacy of its Hazardous Materials usage and procedures.

(c)

At any time, and from time to time, prior to the expiration of the Term, Landlord shall have the right

to conduct appropriate tests of the Property or any portion thereof to demonstrate that Hazardous Materials are present or
that contamination has occurred due to the acts or omissions of a Tenant Party. Tenant shall pay the reasonable costs of such
tests to the extent such tests reveal that Hazardous Materials exist at the Property in violation of this Lease.

(d)

If underground or other storage tanks storing Hazardous Materials installed or utilized by Tenant are

located on the Premises, or are hereafter placed on the Premises by Tenant (or by any other party, if such storage tanks are
utilized by Tenant), then Tenant shall monitor the storage tanks, maintain appropriate records, implement reporting
procedures, properly close any underground storage tanks, and take or cause to be taken all other steps necessary or required
under the applicable Laws. Tenant shall have no responsibility or liability for underground or other storage tanks installed by
anyone other than Tenant unless Tenant utilizes such tanks, in which case Tenant’s responsibility for such tanks shall be as
set forth in this Section. The provisions of this paragraph shall not be construed to permit Tenant to install any underground
or other storage tank.

(e)

Tenant shall promptly report to Landlord any actual or suspected presence of mold or water

intrusion at the Premises.

(f)

Tenant’s obligations under this Article shall survive the expiration or earlier termination of the

Lease. During any period of time needed by Tenant or Landlord after the termination of this Lease to complete the removal
from the Premises of any such Hazardous Materials, Tenant shall be deemed a holdover tenant and subject to the provisions
of Section 12.1.

Subject to Tenant’s obligations under this Lease and under applicable Law, Landlord shall, at its sole cost and expense,
comply with all Environmental Laws with respect to the existence of Hazardous Materials in, on or at the Property as of the
date of this Lease or arising thereafter as a result of the acts or omissions of Landlord or any Landlord Parties. Nothing in
this Section 5.4 or

19

elsewhere in this Lease shall be deemed to make Tenant responsible or liable for any Excluded Matters.

5.5

Odors and Exhaust. Tenant acknowledges that Landlord would not enter into this Lease with Tenant unless

Tenant assured Landlord that under no circumstances will any other occupants of the Building or the Property (including
persons legally present in any outdoor areas of the Property) be subjected to odors or fumes (whether or not noxious), and
that the Building and the Property will not be damaged by any exhaust, in each case from Tenant’s operations. Landlord and
Tenant therefore agree as follows:

(a)

Tenant shall not cause or knowingly permit (or conduct any activities that would cause) any release

of any odors or fumes of any kind from the Premises other than by exhaust systems properly installed for such purposes in
compliance with this Section 5.5 and in a manner consistent with first class laboratory buildings and applicable Laws.

(b)

If the Building has a ventilation system that, in Landlord’s judgment, is adequate, suitable, and

appropriate to vent the Premises in a manner that does not release odors affecting any indoor or outdoor part of the Property,
Tenant shall vent the Premises through such system. If Landlord at any time determines that any existing ventilation system
is inadequate for Tenant’s particular use of the Premises, as reasonably evidenced by Landlord, Tenant shall in compliance
with applicable Laws, at its sole cost and expense, install such additional ventilation systems as are reasonably required to
vent all such additional fumes and odors from the Premises (and remove odors from Tenant’s exhaust stream) as Landlord
reasonably requires, Landlord agreeing to cooperate as reasonably required in connection with the same (at no cost or
liability to Landlord). The placement and configuration of all ventilation exhaust pipes, louvers and other equipment shall be
subject to Landlord’s approval, such approval not to be unreasonably withheld, conditioned, or delayed (unless the same
interferes with other tenants’ use and enjoyment of their respective premises or Landlord’s operation of the Common
Facilities or would otherwise be visible outside of the Premises, in which case Landlord’s approval may be withheld in its
sole discretion). Tenant acknowledges Landlord’s legitimate desire to maintain the Property (indoor and outdoor areas) in an
odor-free manner, and Landlord may require Tenant to abate and remove all odors in a manner that goes beyond the
requirements of Applicable Laws.

(c)

Tenant shall, at Tenant’s sole cost and expense, provide odor eliminators and other devices (such as
filters, air cleaners, scrubbers and whatever other equipment may in Landlord’s judgment be necessary or appropriate from
time to time) to completely remove, eliminate and abate any odors, fumes or other substances in Tenant’s exhaust stream
that, in Landlord’s reasonable judgment, emanate from Tenant’s Premises. Any work Tenant performs under this Section
shall constitute Alterations.

(d) Tenant’s responsibility to remove, eliminate and abate odors, fumes and exhaust shall continue

throughout the Term. Landlord’s approval of any Alterations shall not preclude Landlord from requiring additional measures
to eliminate odors, fumes and other adverse impacts of Tenant’s exhaust stream (as Landlord may designate in Landlord’s
reasonable discretion). Tenant shall install additional equipment as Landlord requires from time to time

20

under the preceding sentence as further set forth above. Such installations shall constitute Alterations.

(e)

If Tenant fails to install satisfactory odor control equipment where required within ten (10) Business
Days after Landlord’s demand made at any time, then Landlord may, without limiting Landlord’s other rights and remedies,
require Tenant to cease and suspend any operations in the Premises that, in Landlord’s reasonable determination, cause
odors, fumes or exhaust. For example, if Landlord determines that Tenant’s production of a certain type of product causes
odors, fumes or exhaust, and Tenant does not install satisfactory odor control equipment within ten (10) Business Days after
Landlord’s request, then Landlord may require Tenant to stop producing such type of product in the Premises unless and
until Tenant has installed odor control equipment reasonably satisfactory to Landlord and otherwise in compliance with this
Section 5.5.

5.6

Acid Neutralization Tank; Chemical Safety Program.

(a)

Tenant has the non-exclusive appurtenant right to use an acid neutralization tank (the “Acid

Neutralization Tank”) that is located in the Building and connected to the Premises. Tenant shall have the right, through the
Term of the Lease, to use the Acid Neutralization Tank and associated connections to the Premises in accordance with
applicable laws. Tenant shall obtain, and maintain, all governmental permits and approvals necessary for Tenant’s particular
use of the Acid Neutralization Tank, as opposed to the use of the Acid Neutralization Tank, generally (which shall be the
responsibility of the Landlord, including without limitation the MWRA Permit for the same). Tenant shall be responsible for
Tenant’s portion, as reasonably allocated by Landlord among tenants utilizing the Acid Neutralization Tank on a
proportionate basis, of all reasonable out of pocket costs, charges and expenses incurred by Landlord from time to time in
connection with or arising out of the operation, use, maintenance, repair or refurbishment of the Acid Neutralization Tank,
including all clean-up costs relating to the use of the Acid Neutralization Tank (collectively, “Tank Costs”) (provided that
Tank Costs shall not include any costs or expenses that are not includable as an Operating Expense under this Lease). Tenant
shall indemnify, save, defend (at Landlord’s option and with counsel reasonably acceptable to Landlord) and hold the
Landlord Indemnitees harmless from and against any and all Claims, including (a) diminution in value of the Premises or
any portion thereof, (b) damages for the loss or restriction on use of rentable or usable space of the Premises, (c) damages
arising from any adverse impact on marketing of space in the Premises or any portion thereof, and (d) sums paid in
settlement of Claims that arise during or after the Term as a result of Tenant’s improper use of the Acid Neutralization Tank,
except to the extent such Claims result from the negligence or willful misconduct of any of the Landlord Parties or by,
through, or under any other tenant in the Building. This indemnification by Tenant includes costs incurred in connection with
any investigation of site conditions or any clean-up, remediation, removal or restoration required by any governmental
authority caused by Tenant’s improper use of the Acid Neutralization Tank.

(b)

Tenant shall establish and maintain a chemical safety program administered by a qualified

individual in accordance with the requirements of the Massachusetts Water Resources Authority (“MWRA”) and any other
applicable governmental authority. Tenant shall be solely responsible for all costs incurred in connection with such chemical
safety

21

program, and Tenant shall provide Landlord with such document as Landlord may reasonably require evidencing Tenant’s
compliance with the requirements of (a) the MWRA and any other applicable governmental authority with respect to such
chemical safety program and (b) this Section 5.6, in each case with respect to Tenant’s use of the Acid Neutralization Tank.
Tenant shall provide all such information regarding Tenant’s activities in the Premises as may reasonably be necessary in
order for Landlord to obtain and maintain during the Term (i) any permit required by the MWRA (“MWRA Permit”) and
(ii) a wastewater treatment operator license from the Commonwealth of Massachusetts with respect to Tenant’s use of the
Acid Neutralization Tank. Tenant shall not introduce anything into the Acid Neutralization Tank serving the Building (x) in
violation of the terms of the MWRA Permit, (y) in violation of applicable Laws or (z) that would interfere with the proper
functioning of any such acid neutralization tank. Landlord shall cooperate with Tenant as reasonably required to obtain any
modifications to the MWRA Permit to the extent necessary to permit Tenant’s use and operations within the Premises, at no
out of pocket cost to Landlord; provided, that (i) any such modifications shall be reasonably acceptable to Landlord, and (ii)
no such modifications shall impose any additional obligations or liability on Landlord, impact any other tenant’s operations
at the Building or use of the Acid Neutralization Tank or impose any restrictions on the use of the Acid Neutralization Tank
or Building (other than to the extent affecting Tenant only).

(c)

In addition, if Tenant fails to comply with the provisions of this Section 5.6, then upon written

notice from Landlord, Tenant shall immediately cease use of the Acid Neutralization Tank until such time as Tenant
complies with the provisions of this Section 5.6, as determined by Landlord.

ARTICLE 6
ASSIGNMENT AND SUBLETTING

6.1

Prohibition.

(a)

Tenant covenants and agrees that neither this Lease nor the term and estate hereby granted, nor any

interest herein or therein, will be assigned, mortgaged, pledged, encumbered or otherwise transferred, whether voluntarily,
involuntarily, by operation of law or otherwise, and that neither the Premises nor any part thereof will be encumbered in any
manner by reason of any act or omission on the part of Tenant, or used or occupied or permitted to be used or occupied, by
anyone other than Tenant, or for any use or purpose other than a Permitted Use, or be sublet (which term, without limitation,
shall include granting of concessions, licenses and the like) in whole or in part, or be offered or advertised for assignment or
subletting by Tenant or any person acting on behalf of Tenant, without, in each case, the prior written consent of Landlord
(all of the foregoing are hereinafter sometimes referred to collectively as “Transfers” and any person to whom any Transfer
is made or sought to be made is hereinafter sometimes referred to as a “Transferee”). Without limiting the foregoing, any
agreement pursuant to which: (x) Tenant is relieved from the obligation to pay, or a third party agrees to pay on Tenant’s
behalf, all or any portion of the Basic Rent or Additional Rent under this Lease; and/or (y) a third party undertakes or is
granted by or on behalf of Tenant the right to assign or attempt to assign this Lease or sublet or attempt to sublet all or any
portion of the Premises, shall for all purposes hereof be deemed to be a Transfer of this Lease and subject to the provisions
of

22

this Article 6. A Transfer under this Article 6 shall also include a sale or other transfer (by one or more transfers) of any of
the following: the voting stock, partnership interests, membership or other equity interests in Tenant (or any other
mechanism such as the issuance of additional stock or the creation of additional partnership or membership interests) which
results in a change of control of Tenant or a sale or other transfer (in one or more transfers) of fifty percent (50%) or more of
the assets of Tenant, as if such transfer were an assignment of this Lease. Notwithstanding the foregoing, if equity interests
in Tenant at any time offered on, or are or become traded on a national securities exchange (as defined in the Securities
Exchange Act of 1934) or any other nationally recognized stock exchange, the transfer or issuance of equity interests in
Tenant on a national securities exchange shall not be deemed an assignment within the meaning of this Article.

(b)

Notwithstanding the foregoing, Landlord’s consent shall not be required under Section 6.1(a) and
Section 6.5 shall not apply to either (x) transactions with an entity into or with which Tenant is merged or consolidated, or
into which Tenant is reorganized, or to which all or substantially all of Tenant’s assets are transferred (a “Successor
Transaction”), or (y) transactions with any entity (an “Affiliate”) which controls or is controlled by Tenant or is under
common control with Tenant; provided and only on condition that in any such event:

(i)

the successor to Tenant has a Tangible Net Worth, computed in accordance with generally

accepted accounting principles consistently applied, at least equal to the greater of (1) the Tangible Net
Worth of Tenant immediately prior to such merger, consolidation or transfer, or (2) the Tangible Net Worth
of Tenant herein named on the date of this Lease,

(ii)

proof satisfactory to Landlord of the Tangible Net Worth of both the transferee and Tenant

shall have been delivered to Landlord at least ten (10) days prior to the effective date of any such
transaction, or if such transaction is required to remain confidential, promptly (i.e., within five (5) business
days) after such transaction,

(iii)

the transfer is for a valid business purpose of Tenant and is not a subterfuge for the

provisions of this Article 6, and

(iv)

the transferee agrees, at least ten (10) days prior to the effective date of any such transaction

or, if such transaction is required to remain confidential, promptly (i.e., within five (5) business days) after
such transaction, directly with Landlord, by written instrument in form satisfactory to Landlord in its
reasonable discretion, to be bound by all the obligations of Tenant hereunder, including, without limitation,
the covenant against further assignment and subletting (provided that no such agreement is required if such
obligations are assumed by operation of law).

(c)

Notwithstanding any provision to the contrary in this Lease, use of less than ten percent (10%) of

the Premises by companies, firms or other entities (each, a “Working Partnership”) (i) who are members of a group with
whom Tenant has a contractual or other relationship providing for cooperative or collaborative research or development
work, (ii) who

23

are or typically might be located by Tenant in one of its facilities, (iii) whose rights to use the Premises are evidenced by a
written, revocable license with less than a two (2) year term, and (iii) whose use of the Premises is not separately demised,
shall not be a Transfer for the purposes of this Article 6 and shall be permitted without the necessity of obtaining Landlord’s
consent thereto, but Tenant shall provide Landlord with prior written notice thereof (which notice shall include the number
of square feet in occupancy by such entities and such other information reasonably required for financing, insurance
(including without limitation, complying with Landlord’s reasonable insurance requirements applicable to the Working
Partnership, such as, naming Landlord and Landlord Parties as additional insured on the Working Partnership’s commercial
general liability insurance coverage and providing Landlord with a certificate of insurance evidencing the same) and other
risk management purposes).

6.3

Landlord’s Consent.

(a)

If Tenant desires Landlord’s consent to any Transfer, Tenant shall notify Landlord in writing, which
notice (the “Transfer Notice”) shall include (i) the proposed effective date of the Transfer, which shall not be less than thirty
(30) days nor more than one hundred eighty (180) days after the date of delivery of the Transfer Notice, (ii) a description of
the portion of the Premises to be transferred, (iii) all of the material terms of the proposed Transfer and the consideration
therefor, including the name and address of the proposed Transferee, and the proposed documentation effectuating the
proposed Transfer, including all operative documents to evidence such Transfer and all agreements incidental or related to
such Transfer, (iv) current financial statements of the proposed Transferee certified by an officer, partner or owner thereof,
business credit and personal references and history of the proposed Transferee and any other information reasonably
required by Landlord which will enable Landlord to determine the financial responsibility, character, and reputation of the
proposed Transferee, nature of such Transferee’s business and proposed use of the Premises.

(b)

In the event Landlord does not exercise its options pursuant to Section 6.5 below to recapture the

Premises or terminate this Lease, Landlord’s consent to a proposed Transfer shall not be unreasonably withheld, conditioned
or delayed, provided and upon condition that:

(i)

There shall not be an Event of Default that remains uncured or other event or condition that

with the passage of time or the giving of notice, or both, would constitute an Event of Default;

(ii)

In Landlord’s reasonable judgment the proposed Transferee is engaged in a business which

is in keeping with the then standards of the Building and Property and the proposed use is limited to the
Permitted Use;

(iii)

The proposed Transferee is a reputable entity and has sufficient financial worth and stability

in light of the responsibilities to be undertaken, based on evidence provided by Tenant (and others) to
Landlord, as determined by Landlord in its reasonable discretion;

24

(iv)

Neither (A) the proposed Transferee nor (B) any person or entity which, directly or

indirectly, controls, is controlled by, or is under common control with, the proposed Transferee, is then an
occupant of any part of the Property (unless there is no available space for lease in the Building and none
coming available in the following eighteen (18) month period);

(v)

The proposed Transferee is not a person or entity with whom Landlord is then, or during the

preceding nine (9) months has been, actively negotiating to lease space at the Property;

(vi)

The proposed Transfer shall be in form reasonably satisfactory to Landlord and shall

comply with the applicable provisions of this Article 6;

(vii)

Tenant shall not have advertised or publicized the availability of the Premises at rental rate
less than the base rent and additional rent at which Landlord is then offering to lease other space located in
the Building without prior notice to and approval by Landlord, which approval shall not be unreasonably
withheld, conditioned or delayed;

(viii) With respect to a proposed sublease, the proposed sublease involves, in Landlord’s
reasonable judgment, a portion of the Premises which is independently leasable space (taking into account
any modifications proposed by Tenant that are reasonably acceptable to Landlord);

(ix) With respect to and after taking into account a proposed sublease, there will not be more

two subtenants occupying the Premises;

(x)

The character of the business to be conducted or the proposed use of the Premises by the
proposed Transferee or the identity of the proposed Transferee will not create or increase the likelihood of
any labor disputes, disharmony, strikes or any other form of protests occurring at the Property;

(xi)

The proposed Transfer shall not have (or potentially have) any adverse effect on any real

estate investment trust qualification requirements of Landlord or any of its affiliates or otherwise cause
Landlord or any of its affiliates to be in violation of any Laws to which Landlord or such affiliate is subject,
including, without limitation, the Employment Retirement Security Act of 1974, as reasonably evidenced by
Landlord;

(xii)

The holder of any Superior Mortgage and/or Superior Lease, as applicable, consents to such

Transfer, to the extent required under the applicable instrument (as affected by any SNDA); and

(xiii) Neither the identity nor business of the proposed Transferee would cause Landlord to be in

violation of any covenant or restriction contained in another lease at the Property.

25

6.4

Acceptance of Rent. If this Lease is assigned, or if the Premises or any part thereof is sublet or occupied by

anyone other than Tenant, whether or not in violation of the terms and conditions of the Lease, Landlord may, at any time
and from time to time (but only following an Event of Default under the Lease in the event Tenant sublets the Premises),
collect rent and other charges from the Transferee, and apply the net amount collected to the rent and other charges herein
reserved, but no such Transfer, collection or modification of any provisions of this Lease shall be deemed a waiver of this
covenant, or the acceptance of the Transferee as a tenant or a release of Tenant from the further performance of covenants on
the part of Tenant to be performed hereunder. Any consent by Landlord to a particular Transfer or other act for which
Landlord’s consent is required under paragraph (a) of Section 6.1 shall not in any way diminish the prohibition stated in
paragraph (a) of Section 6.1 as to any further such Transfer or other act or the continuing liability of the original named
Tenant. No Transfer hereunder shall relieve Tenant from its obligations hereunder, and Tenant shall remain fully and
primarily liable therefor. Landlord may revoke any consent by Landlord to a particular Transfer if the Transfer does not
provide that the Transferee agrees to be independently bound by and upon all of the covenants, agreements, terms,
provisions and conditions set forth in this Lease on the part of Tenant to be kept and performed (to the extent applicable to
any subleased portion of the Premises, in the event of a sublease).

6.5

Excess Payments. If Tenant assigns this Lease or sublets the Premises or any portion thereof, Tenant shall

pay to Landlord as Additional Rent fifty percent (50%) of the amount, if any, by which (a) any and all compensation
received by Tenant as a result of such Transfer, net only of reasonable expenses actually incurred by Tenant in consideration
such Transfer for brokerage commissions, improvement expenses and allowances (prorated over the term of the Transfer),
exceeds (b) in the case of an assignment, the Basic Rent and Additional Rent under this Lease, and in the case of a
subletting, the portion of the Basic Rent and Additional Rent allocable to the portion of the Premises subject to such
subletting. Such payments shall be made by Tenant, within thirty (30) days following Tenant’s receipt of the same.
Notwithstanding the foregoing, the provisions of this Section shall impose no obligation on Landlord to consent to an
assignment of this Lease or a subletting of all or a portion of the Premises.

6.6

Landlord’s Recapture Right. Notwithstanding anything herein to the contrary, in addition to withholding

or granting consent with respect to any proposed Transfer, Landlord shall have the right, to be exercised in writing within
thirty (30) days after receipt of a Transfer Notice, to terminate this Lease (in the event of (i) a proposed assignment or (ii)
any sublease of at least 50% of the Premises for more than three years). In any such event, this Lease shall terminate as of
the date (the “Recapture Date”) which is the later of (a) sixty (60) days after the date of Landlord’s election, and (b) the 
proposed effective date of such Transfer, as if such date were the last day of the Term of this Lease unless Tenant rescinds its 
Transfer request within ten (10) business days following any such termination notice from Landlord.  .

6.7

Further Requirements. Tenant shall reimburse Landlord within 30 days after invoice, as Additional Rent,
for any out-of-pocket costs (including reasonable attorneys’ fees and expenses) incurred by Landlord in connection with any
actual or proposed assignment or sublease or other act described in paragraph (a) of Section 6.1, whether or not
consummated, including the costs of making investigations as to the acceptability of the proposed assignee or

26

subtenant, but in any event not to exceed $5,000 in the aggregate with respect to any one Transfer. Any sublease to which
Landlord gives its consent shall not be valid unless and until Tenant and the sublessee execute a commercially reasonable
consent agreement in form and substance satisfactory to Landlord in its reasonable discretion and a fully executed
counterpart of such sublease has been delivered to Landlord. Any sublease shall provide that: (i) the term of the sublease
ends no later than one day before the last day of the Term of this Lease; (ii) such sublease is subject and subordinate to this
Lease; (iii) Landlord may enforce the provisions of the sublease, including collection of rents following an Event of Default;
and (iv) in the event of termination of this Lease or reentry or repossession of the Premises by Landlord, Landlord may, at its
sole discretion and option, take over all of the right, title and interest of Tenant, as sublessor, under such sublease, and such
subtenant shall, at Landlord’s option, attorn to Landlord, but nevertheless Landlord shall not (A) be liable for any previous
act or omission of Tenant under such sublease; (B) be subject to any defense or offset previously accrued in favor of the
subtenant against Tenant; or (C) be bound by any previous modification of such sublease made without Landlord’s written
consent or by any previous prepayment of more than one month’s rent.

BE FURNISHED BY LANDLORD

7.1

Landlord Repairs.

(a)

Except as otherwise provided in this Lease, Landlord agrees to keep in good order, condition and

repair and in compliance with applicable Laws, the roof and roof system, the Base Building and Base Building Systems (but
specifically excluding any supplemental heating, ventilation or air conditioning equipment or other supplemental systems
exclusively serving the Premises that are currently installed, installed as part of Landlord’s Work or at Tenant’s request or as
a result of Tenant’s requirements in excess of Building standard design criteria, including, without limitation, all systems and
equipment supporting Tenant’s laboratory, research and development operations (“Tenant’s Laboratory Systems”)), all
insofar as they affect the Premises, except that Landlord shall in no event be responsible to Tenant for the repair of glass in
the interior Premises, the doors (and related glass and finish work) leading to the Premises, or any condition in the Premises
or the Building caused by any act or neglect of Tenant, its invitees or contractors. Landlord shall also keep and maintain all
Common Facilities in a good and clean order, condition and repair, free of snow and accumulation of dirt and rubbish and
with reasonable treatment of ice on driveways and pedestrian walkways, and shall keep and maintain all landscaped areas at
the Building in a neat and orderly condition. Landlord shall not be responsible to make any improvements or repairs to the
Building other than as expressly in this Section 7.1 provided, unless expressly provided otherwise in this Lease.

(b)

Landlord shall never be liable for any failure to make repairs which Landlord has undertaken to

make under the provisions of this Section 7.1 or elsewhere in this Lease, unless Tenant has given notice to Landlord of the
need to make such repairs, and Landlord has failed to commence to make such repairs within a reasonable time after receipt
of such notice, or fails to proceed with reasonable diligence to complete such repairs.

27

7.2

Tenant Repairs; Compliance with Laws.

(a)

Tenant shall keep and maintain the Premises and the Improvements, Landlord’s Work, Tenant’s

trade fixtures and appurtenances therein or thereon installed by or on behalf of Tenant (including, without limitation,
Tenant’s Laboratory Systems, electrical and mechanical systems not considered part of the Base Building Systems or any
portion of such systems that have been installed as Landlord’s Work or Alterations for the exclusive use and benefit of
Tenant such as additional HVAC equipment, hot water heaters, electronic, data, phone, and other telecommunications
cabling and related equipment, and security or telephone systems for the Premises), neat and clean and in good order,
condition and repair, excepting only those repairs for which Landlord is responsible under the terms of this Lease,
reasonable wear and tear of the Premises, and damage by fire or other casualty or as a consequence of the exercise of the
power of eminent domain; and Tenant shall surrender the Premises, at the end of the Term, in such condition. Subject to
Section 10.5 regarding waiver of subrogation, Tenant shall be responsible for the cost of repairs which may be made
necessary by reason of damage to the Building caused by any act or neglect of Tenant, or its employees, contractors or
invitees (including any damage by fire or other casualty arising therefrom).

(b)

Tenant shall comply with all Laws from time to time in effect and all directions, rules and

regulations of governmental agencies having jurisdiction, and the standards recommended by the local Board of Fire
Underwriters applicable to the Premises and Tenant’s use and occupancy thereof and its business and operations therein, and
shall, at Tenant’s expense, obtain all permits, licenses and the like required thereby. Notwithstanding the foregoing, Tenant
shall not be obligated to make structural repairs or alterations to the Premises in order to comply with any Laws unless the
need for such repairs or alterations arises from (i) the specific manner and nature of Tenant’s use or occupancy of the
Premises, as distinguished from the Permitted Use, generally, (ii) the manner of conduct of Tenant’s business or operation of
its installations, equipment or other property therein, (b) any cause or condition created by or at the instance of the Tenant,
including, without limitation, the performance of the Landlord’s Work and/or any other Alterations made by Tenant, or (iii) a
breach by Tenant of any provisions of this Lease. Any of the foregoing conditions caused by any employee, agent,
contractor, or subtenant of Tenant or any other party claiming by, through, or under Tenant shall be attributable to Tenant for
purposes of this Lease. Tenant shall also be responsible for the cost of compliance with all present and future Laws in respect
of the Building to the extent arising from any of the causes set forth in clauses (i) through (iii) above of this Section 7.2(b),
in which event, at Landlord’s election, Tenant shall (x) either be responsible to perform, at Tenant's sole cost and expense,
such repairs or alterations, whether or not such compliance requires work which is structural or non-structural, ordinary or
extraordinary, foreseen or unforeseen, or (y) be responsible for Landlord’s costs to perform such repairs or alterations and
shall reimburse Landlord for such costs, from time to time, within thirty (30) days of Landlord invoicing Tenant therefor

(c)

If repairs are required to be made by Tenant pursuant to the terms hereof, and Tenant fails to make

the repairs within applicable notice and cure periods, upon not less than ten (10) days’ prior written notice (except that no
notice shall be required in the event of an emergency), Landlord may make or cause such repairs to be made (but shall not be
required to do so), and the provisions of Section 14.4 shall be applicable to the costs thereof. Landlord shall

28

not be responsible to Tenant for any loss or damage whatsoever that may accrue to Tenant’s stock or business by reason of
Landlord’s making such repairs, except to the extent arising out of the negligence or willful misconduct of Landlord or any
Landlord Party.

7.3

Floor Load - Heavy Machinery.

(a)

Tenant shall not place a load upon any floor in the Premises exceeding the load it was designed to
carry, or such lower limit as may be proscribed by applicable Law. Landlord reserves the right to proscribe the weight and
position of all business machines and mechanical equipment, including safes, which shall be placed so as to distribute the
weight. Business machines and mechanical equipment shall be placed and maintained by Tenant at Tenant’s expense (except
to the extent included in Landlord’s Work) in settings sufficient, in Landlord’s reasonable judgment, to absorb and prevent
vibration, noise and annoyance. Tenant shall not move any safe, heavy machinery, heavy equipment, oversized freight, bulky
matter or oversized fixtures into or out of the Building without Landlord’s prior written consent, which consent shall not be
unreasonably withheld or delayed and may include a requirement to provide applicable insurance, naming Landlord as an
additional insured, in such amounts as Landlord may reasonably require.

(b)

If any such safe, machinery, equipment, freight, bulky matter or fixtures requires special handling,

Tenant agrees to employ only persons holding a Master Rigger’s license to do such work, and that all work in connection
therewith shall comply with applicable Laws. Any such moving shall be at the sole risk and hazard of Tenant, and Tenant
will exonerate, indemnify and save Landlord harmless against and from any liability, loss, injury, claim or suit resulting
directly or indirectly from such moving, except to the extent resulting from Landlord’s negligence or willful misconduct.

7.4

Utility Services.

(a)

Landlord shall, on Monday through Friday from 7:00 a.m. to 6:00 p.m. in the office portion of the

Premises and 24 hours, seven (7) days a week in the laboratory areas (including the animal holding facility) of the Premises,
furnish heating and cooling as normal seasonal changes may require to provide reasonably comfortable space temperature
and ventilation for occupants of the Premises and for use of the animal holding facility and Tenant’s laboratory operations
under normal business operation at an occupancy level not exceeding the occupancy requirements for the Building and
applicable Laws (but in any event, Landlord will provide make-up air to the animal holding facility and Tenant’s laboratory
portions of the Property at a rate of 2.0 CFM/square foot and conditioning air to the office area portions of the Property at a
rate of 1.2 CFM/square foot (provided, however, that such obligation of Landlord will only be applicable if the breakdown
between the portion of the Premises used for office space and the portion of the Premises used for laboratory (including the
animal holding facility) remains as contemplated by the Baseline Plans (as defined in the Work Letter)) and an electrical
load not exceeding twelve (12) watts per rentable square foot. If Tenant shall require air conditioning, heating or ventilation
to the office areas of the Premises outside the hours and days above specified, Landlord may furnish such service and Tenant
shall pay therefor such charges as may from time to time be in effect for the Building upon demand as Additional Rent. In
the event Tenant introduces into the Premises personnel or equipment which overloads the capacity

29

of the Building system or in any other way interferes with the system’s ability to perform adequately its proper functions and
does not cure the same within applicable notice and cure periods, supplementary systems may, if and as needed, at
Landlord’s option, be provided by Landlord, and the cost of such supplementary systems shall be payable by Tenant to
Landlord upon demand as Additional Rent.

(b)

Landlord shall supply electricity to the Premises for the Permitted Use to meet, but not exceed, a

demand requirement not to exceed twelve (12) watts per rentable square foot of the Premises for standard single-phase 120
volt alternating current, and Tenant agrees in its use of the Premises (i) not to exceed such requirements (including without
limitation, that such usage will not exceed twelve (12) watts per rentable square foot of the Premises for standard single-
phase 120 volt alternating current), and (ii) that its total connected load will not exceed the maximum from time to time
permitted under applicable governmental regulations. If, without in any way derogating from the foregoing limitation,
Tenant shall require electricity in excess of the requirements set forth above, Tenant shall notify Landlord and Landlord may
(without being obligated to do so) supply such additional service or equipment at Tenant’s sole cost and expense. Landlord
shall purchase and install, at Tenant’s expense based on the actual cost of the same, all lamps, tubes, bulbs, starters and
ballasts. Landlord shall install check meters serving the Premises as part of the Landlord’s Work and shall invoice Tenant for
the actual costs of electricity provided to the Premises based on the usage shown on the check meter serving the Premises
and Tenant shall pay Landlord the invoiced amount as Additional Rent hereunder within thirty (30) days after receipt of each
such invoice. In order to assure that the foregoing requirements are not exceeded and to avert possible adverse effect on the
Building’s electric system, Tenant shall not, without Landlord’s prior written consent, connect any fixtures, appliances or
equipment to the Building’s electric distribution system drawing more than 15 amps at 120/208 volts. All charges to Tenant
under this paragraph shall be due and payable as Additional Rent within thirty (30) days after receiving Landlord’s invoice
therefor.

(c)

From time to time during the Term of this Lease, Landlord shall have the right to have an electrical

consultant selected by Landlord make a survey of Tenant’s electric usage, the result of which survey shall be conclusively
binding upon Landlord and Tenant, absent manifest error. In the event that such survey shows that Tenant has exceeded the
requirements set forth in paragraph (b), in addition to any other rights Landlord may have hereunder, Tenant shall, upon
demand, reimburse Landlord for the cost of such survey and the cost, as determined by such consultant, of electricity usage
in excess of such requirements as Additional Rent.

(d)

Landlord shall have the right to discontinue furnishing electricity to the Premises at any time upon

not less than thirty (30) days’ notice to Tenant; provided that Landlord shall, at Tenant’s expense, separately meter the
Premises directly to the applicable public utility company. If Landlord exercises such right, from and after the effective date
of such discontinuance, Landlord shall not be obligated to furnish electricity to the Premises, and Landlord shall permit
Landlord’s existing wires, risers, conduits and other electrical equipment of Landlord to be used to supply electricity to
Tenant, provided that the limits set forth in paragraph (b) shall not be exceeded, and Tenant shall be responsible for
payment of all electricity charges directly to such utility.

30

7.5

Other Services.

Landlord shall also provide, at all times during the Term:

(a)

Passenger elevators service from the existing passenger elevators system and freight elevator service

in common with Landlord and others entitled thereto.

(b)

Warm water for lavatory purposes and cold water (at temperatures supplied by the city in which the
Property is located) for laboratory, drinking, lavatory and toilet purposes. Such water shall be made available from the main
connection point for such service on the floor on which the Premises is located and the distribution of water within the
Premises shall be provided by Tenant. If Tenant uses water for any purpose other than for the purposes set forth above,
Landlord may assess a reasonable charge for the additional water so used, or install a water meter and thereby measure
Tenant’s water consumption for all purposes. In the latter event, unless such meter exists as of the Commencement Date,
Tenant shall pay the cost of the meter and the cost of installation thereof as Additional Rent upon demand and shall keep
such meter and installation equipment in good working order and repair. Tenant agrees to pay for water consumed, as shown
on such meter, together with the sewer charge based on such meter charges, within 30 days after invoice, and in the event
Tenant fails timely to make any such payment, Landlord may pay such charges and collect the same from Tenant upon
demand as Additional Rent.

(c)

Cleaning and janitorial services only to the Common Facilities and Landlord shall provide a
dumpster and/or compactor at the loading dock (or such other location reasonably determined by Landlord) Building
tenants’ use for the disposal of non-hazardous/non-controlled substances. Landlord will not provide cleaning and janitorial
services to the Premises, which shall be the sole obligation of Tenant.

(d)

Access to the Premises and Common Facilities serving the same at all times, subject to reasonable

security and safety precautions from time to time in effect, if any, and subject always to reasonable restrictions based on
emergency conditions.

(e)

Landlord may from time to time, but shall not be obligated to, provide one or more attendants in or

about the lobby of the Building, and the costs of such services shall constitute Operating Expenses in accordance with the
provisions of Article 9 hereof. Tenant expressly acknowledges and agrees that, if provided: (i) such attendants shall not
serve as police officers, and will be unarmed, and will not be trained in situations involving potentially physical
confrontation; and (ii) such attendants will be solely an amenity to tenants of the Building for purposes such as assisting
visitors and invitees of tenants and others in the Building, monitoring fire control and alarm equipment, and summoning
emergency services to the Building as and when needed, and not for the purpose of securing any individual tenant premises
or guaranteeing the physical safety of Tenant’s Premises or of Tenant’s employees, agents, contractors or invitees. The
Building contains a card key access security system controlling access to Building and the elevators. Landlord shall provide
a reasonable initial number of access cards to Tenant. The actual out of pocket costs for Landlord to provide any replacement
cards shall be at Tenant’s expense. If and to the extent that Tenant desires to provide security for the Premises or for such
persons or their property, Tenant shall be responsible for so doing, after having first consulted

31

with Landlord and after obtaining Landlord’s written consent, which shall not be unreasonably withheld, conditioned, or
delayed, Landlord acknowledging that Tenant may install a security system serving the Premises subject to the provisions of
Section 5.2. Landlord expressly disclaims any and all responsibility and/or liability for the physical safety of Tenant’s
property, and for that of Tenant’s employees, agents, contractors and invitees, and, without in any way limiting the operation
of Article 10 hereof, Tenant, for itself and its agents, contractors, invitees and employees, hereby expressly waives any
claim, action, cause of action or other right which may accrue or arise as a result of any damage or injury to the person or
property of Tenant or any such agent, invitee, contractor or employee, except to the extent arising out of the negligence or
willful misconduct of Landlord or the negligence of any Landlord Party. Tenant agrees that, as between Landlord and
Tenant, it is Tenant’s responsibility to advise its employees, agents, contractors and invitees as to necessary and appropriate
safety precautions within the Property.

(f) The loading dock, receiving area and the freight elevator shall be shared by Building tenants. Tenant and
its authorized contractors and cleaning personnel shall have 24-hour access to the loading docks and disposal areas included
within the Common Facilities, subject to Landlord’s reasonable rules and regulations regarding the timing of use for certain
activities.

7.6

Interruption of Service.

(a)

Landlord reserves the right to curtail, suspend, interrupt and/or stop the supply of water, sewage,

electrical current, cleaning, and other services, and to curtail, suspend, interrupt and/or stop use of entrances and/or lobbies
serving access to the Building, or other portions of the Property, for reasonable periods, without thereby incurring any
liability to Tenant, when necessary by reason of accident or emergency, or for repairs, alterations, replacements or
improvements in the judgment of Landlord reasonably exercised desirable or necessary, or when prevented from supplying
such services or use due to any act or neglect of Tenant or Tenant’s agents employees, contractors or invitees or any person
claiming by, through or under Tenant or by Force Majeure, including, but not limited to, strikes, lockouts, difficulty in
obtaining materials, accidents, laws or orders, or inability, by exercise of reasonable diligence, to obtain electricity, water,
gas, steam, coal, oil or other suitable fuel or power. No diminution or abatement of rent or other compensation, nor any
direct, indirect or consequential damages shall or will be claimed by Tenant as a result of, nor shall this Lease or any of the
obligations of Tenant be affected or reduced by reason of, any such interruption, curtailment, suspension or stoppage in the
furnishing of the foregoing services or use, irrespective of the cause thereof. The failure or omission on the part of Landlord
to furnish any of the foregoing services or use as provided in this paragraph shall not be construed as an eviction of Tenant,
actual or constructive, nor entitle Tenant to an abatement of rent, nor to render the Landlord liable in damages, nor release
Tenant from prompt fulfillment of any of its covenants under this Lease.

(b)

Notwithstanding anything to the contrary contained in this Lease, if all or a significant portion of the

Premises are rendered unusable for the normal conduct of Tenant’s business and Tenant, in fact, ceases to use the affected
area of the Premises for the normal conduct of its business as a result of an interruption or failure of utilities caused by an
event within the reasonable control of Landlord to remedy (an “Abatement Event”), then Tenant shall give Landlord notice
of such Abatement Event, and if such Abatement Event continues for five

32

(5) consecutive Business Days after Landlord’s receipt of any such notice (the “Eligibility Period”), then the Basic Rent and
Tenant’s Proportionate Share of Operating Expenses and Taxes, and any other Escalation Charges, shall be abated or
reduced, as the case may be, commencing after the expiration of the Eligibility Period and continuing for such time that
Tenant continues to be so prevented from using, and does not use, the Premises or a portion thereof, in the proportion that
the rentable area of the portion of the Premises that Tenant is prevented from using, and does not use, bears to the total
rentable area of the Premises; provided, however, in the event that Tenant is prevented from using, and does not use, a
portion of the Premises for a period of time in excess of the Eligibility Period and the remaining portion of the Premises is
not sufficient to allow Tenant to effectively conduct its business therein, and if Tenant does not conduct its business from
such remaining portion, then for such time after expiration of the Eligibility Period during which Tenant is so prevented from
effectively conducting its business therein, the Basic Rent and Tenant’s Share of Operating Expenses and Taxes, and any
other Escalation Charges, for the entire Premises shall be abated for such time as Tenant continues to be so prevented from
using, and does not use, the Premises. If, however, Tenant recommences normal business operations in any portion of the
Premises during such period, the Basic Rent and Tenant’s Share of Operating Expenses and Taxes, and any other Escalation
Charges, allocable to such portion, based on the proportion that the rentable area of such portion of the Premises bears to the
total rentable area of the Premises, shall be payable by Tenant from the date Tenant recommences normal business
operations in such portion of the Premises. The foregoing rights to abate Basic Rent and Tenant’s Share of Operating
Expenses and Taxes, and any other Escalation Charges, in this Section 7.6 shall be Tenant’s sole and exclusive remedies at
law or in equity for an Abatement Event. If an Abatement Event continues for a period of more than 270 days, then Tenant
shall have the right to terminate this Lease upon 30 day’s prior written notice to Landlord (provided that such termination
shall be of no force or affect if such Abatement Event ceases within such 30 days period). Except as provided in this Section
7.6, nothing contained herein shall be interpreted to mean that Tenant is excused from paying rent due hereunder.

ARTICLE 8
REAL ESTATE TAXES

8.1

Payments on Account of Real Estate Taxes.

(a)

“Tax Year” shall mean a twelve-month period commencing on July 1 and falling wholly or partially

within the Term, and “Taxes” shall mean (i) all taxes, assessments (special or otherwise), levies, fees and all other
government levies, exactions and charges of every kind and nature, general and special, ordinary and extraordinary, foreseen
and unforeseen, which are, at any time prior to or during the Term, imposed or levied upon or assessed by governmental
authorities against the Property or any portion thereof, or against any Basic Rent, Additional Rent or other rent of any kind
or nature payable to Landlord by anyone on account of the ownership, leasing or operation of the Property, or which arise on
account of or in respect of the ownership, development, leasing, operation or use of the Property or any portion thereof; (ii)
all gross receipts taxes or similar taxes imposed or levied by governmental authorities upon, assessed against or measured by
any Basic Rent, Additional Rent or other rent of any kind or nature or other sum payable to Landlord by anyone on account
of the ownership, development,

33

leasing, operation, or use of the Property or any portion thereof; (iii) all value added, use and similar taxes at any time levied,
assessed or payable by governmental authorities on account of the ownership, development, leasing, operation, or use of the
Property or any portion thereof; and (iv) reasonable expenses of any proceeding for abatement of any of the foregoing items
included in Taxes; but the amount of special taxes or special assessments included in Taxes shall be limited to the amount of
the installment (plus any interest, other than penalty interest, payable thereon) of such special tax or special assessment
required to be paid during the year in respect of which such Taxes are being determined. There shall be excluded from Taxes
all income, estate, succession, inheritance and transfer taxes of Landlord; provided, however, that if at any time during the
Term, the present system of ad valorem taxation of real property shall be changed so that a capital levy, franchise, income,
profits, sales, rental, use and occupancy, or other new or additional tax or charge shall in whole or in part be substituted for,
or added to, such ad valorem tax and levied against, or be payable by, Landlord with respect to the Property or any portion
thereof, such tax or charge shall be included in the term “Taxes” for the purposes of this Article but only to the extent
calculated as if the Building and the Property were the only real estate owned by Landlord. Taxes shall exclude any Taxes
assessed on future development, or any other building located on the Property, or the portions of the Property allocable to
such future development or buildings, any interest or penalties resulting from the late payment of Taxes by Landlord (except
to the extent due to Tenant’s failure to make timely payments), transfer taxes; any environmental assessments, charges or
liens arising in connection with the remediation of Hazardous Materials from the Building or Property (subject to Tenant’s
obligations hereunder); costs or fees payable to public authorities in connection with any future construction of additional
buildings or similar improvements on the Property (including any such fees for transit, housing, schools, open space, child
care, arts programs, traffic mitigation measures, environmental impact reports and traffic studies); and reserves for future
Taxes.

(b)

For each Tax Year during the Term, commencing on the Commencement Date, Tenant shall pay to

Landlord, as an Escalation Charge, an amount equal to Tenant’s Proportionate Share of Taxes for each Tax Year, such
amount to be apportioned for any portion of a Tax Year in which the Commencement Date falls or the Term expires.

(c)

Estimated payments by Tenant on account of Taxes shall be made on the first day of each and every

calendar month during the Term of this Lease, in the fashion herein provided for the payment of Basic Rent. The monthly
amount so to be paid to Landlord shall be sufficient to provide Landlord by the time real estate tax payments are due with a
sum equal to Tenant’s required payment, as reasonably estimated by Landlord from time to time, on account of Taxes for the
then current Tax Year. Promptly after receipt by Landlord of bills for such Taxes, Landlord advise Tenant of the amount
thereof and the computation of Tenant’s payment on account thereof, and at Tenant’s request, Landlord shall provide Tenant
with copies of the same. If estimated payments theretofore made by Tenant for the Tax Year covered by such bills exceed the
required payment on account thereof for such Tax Year, Landlord shall credit the amount of overpayment against subsequent
obligations of Tenant on account of Taxes (or promptly refund such overpayment if the Term of this Lease has ended and
Tenant has no further obligation to Landlord); but if the required payments on account thereof for such Tax Year are greater
than estimated payments theretofore made on account thereof for such Tax Year, Tenant shall pay the difference to Landlord
within thirty (30) days after being so advised by Landlord,

34

and the obligation to make such payment for any period within the Term shall survive expiration of the Term.

8.2

Abatement. If Landlord shall receive any tax refund or reimbursement of Taxes or sum in lieu thereof with

respect to any Tax Year all or any portion of which falls within the Term, then out of any balance remaining thereof after
deducting Landlord’s reasonable, out of pocket expenses in obtaining such refund, Landlord shall, provided there does not
then exist an Event of Default, credit an amount equal to such refund or reimbursement or sum in lieu thereof (exclusive of
any interest, and apportioned if such refund is for a Tax Year a portion of which falls outside the Term,) multiplied by
Tenant’s Proportionate Share against the monthly installments of Escalation Charges next due under this Lease (or refund
such amount to Tenant if the Term has ended and Tenant has no further obligations to Landlord); provided, that in no event
shall Tenant be entitled to a credit in excess of the payments made by Tenant on account of Taxes for such Tax Year pursuant
to paragraph (b) of Section 8.1.

ARTICLE 9
OPERATING EXPENSES

9.1

Definitions. “Operating Year” shall mean each calendar year all or any part of which falls within the Term,
and “Operating Expenses” shall mean the aggregate costs and expenses incurred by Landlord with respect to the operation,
administration, cleaning, insuring, repair, maintenance, replacement and management of the Property, including, without
limitation, the costs and expenses set forth in Exhibit E attached hereto.

9.2

Tenant’s Payment of Operating Expenses.

(a)

For each Operating Year during the Term, commencing on the Commencement Date, Tenant shall

pay to Landlord, as an Escalation Charge, an amount equal to Tenant’s Proportionate Share of Operating Expenses, such
amount to be apportioned for any portion of an Operating Year in which the Commencement Date falls or the Term of this
Lease ends.

(b)

Estimated payments by Tenant on account of Operating Expenses shall be made on the first day of
each and every calendar month during the Term of this Lease, in the fashion herein provided for the payment of Basic Rent.
The monthly amount so to be paid to Landlord shall be sufficient to provide Landlord by the end of each Operating Year a
sum equal to Tenant’s required payment, as reasonably estimated by Landlord from time to time during each Operating Year,
on account of Operating Expenses for such Operating Year. Landlord shall submit to Tenant a reasonably detailed accounting
of Operating Expenses for such Operating Year, and Landlord shall certify to the accuracy thereof. If estimated payments
theretofore made for such Operating Year by Tenant exceed Tenant’s required payment on account thereof for such
Operating Year according to such statement, Landlord shall credit the amount of overpayment against subsequent obligations
of Tenant with respect to Operating Expenses (or promptly refund such overpayment if the Term of this Lease has ended and
Tenant has no further obligation to Landlord); but if the required payments on account thereof for such Operating Year are
greater than the estimated payments (if any) theretofore made on account thereof for such

35

Operating Year, Tenant shall make payment to Landlord within thirty (30) days after being so advised by Landlord, and the
obligation to make such payment for any period within the Term shall survive expiration of the Term. Amounts for
Operating Expenses not charged to Tenant by the date that is one year following the Operating Year in which they are
occurred shall be deemed waived.

(c)

Tenant shall have the right at its own expense to inspect the books and records of Landlord

pertaining to Operating Expenses and Taxes once in any calendar year by any employee of Tenant or by a certified public
accountant mutually acceptable to Landlord and Tenant (provided such certified public accountant charges for its service on
an hourly basis and not based on a percentage of any recovery or similar incentive method) at reasonable times, and upon
reasonable written notice to Landlord as hereinafter provided. Tenant’s right to inspect such books and records is conditioned
upon Tenant first paying Landlord the full amount billed by Landlord. Within ninety (90) days after receipt of Landlord’s
annual reconciliation of Operating Expenses and Taxes, Tenant shall have the right, after at least thirty (30) days prior
written notice to Landlord, to inspect at the offices of Landlord or its property manager, the books and records of Landlord
pertaining solely to the Operating Expenses and Taxes for the immediately preceding calendar year covered in such annual
reconciliation statement. All expenses of the inspection shall be borne by Tenant and must be completed within fifteen (15)
days after commencement of such inspection. If Tenant’s inspection reveals a discrepancy in the comparative annual
reconciliation statement, Tenant shall deliver a copy of the inspection report and supporting calculations to Landlord within
thirty (30) days after completion of the inspection. If Tenant and Landlord are unable to resolve the discrepancy within thirty
(30) days after Landlord’s receipt of the inspection report, either party may upon written notice to the other have the matter
decided by an inspection by an independent certified public accounting firm approved by Tenant and Landlord (the “CPA
Firm”), which approval shall not be unreasonably withheld or delayed. If the inspection by the CPA Firm shows that the
actual aggregate amount of Operating Costs or Taxes payable by Tenant is greater than the amount previously paid by Tenant
for such accounting period, Tenant shall pay Landlord the difference within thirty (30) days. If the inspection by the CPA
Firm shows that the actual applicable amount is less than the amount paid by Tenant, then the difference shall be applied in
payment of the next estimated monthly installments of Operating Costs and/or Taxes owing by Tenant, or in the event such
accounting occurs following the expiration of the Term hereof, such difference shall be refunded to Tenant. Tenant shall pay
for the cost of the inspection by the CPA Firm, unless such inspection shows that Landlord overstated the aggregate amount
Operating Costs or Taxes by more than five percent (5%), in which case Landlord shall pay for the cost of the inspection by
the CPA Firm.

Tenant acknowledges and agrees that any information revealed in the above described inspection may contain proprietary
and sensitive information and that significant damage could result to Landlord if such information were disclosed to any
party other than Tenant’s auditors. Tenant shall not in any manner disclose, provide or make available any information
revealed by the inspection to any person or entity without Landlord’s prior written consent, which consent may be withheld
by Landlord in its sole and absolute discretion.

9.3

Gross-Up Provision. If the Property is not at least ninety-five percent (95%) occupied, in the aggregate,

during any calendar year of the Term of this Lease, or if Landlord is

36

not supplying services to at least ninety-five percent (95%) of the Building Rentable Area, at any time during any calendar
year of the Term, actual Operating Expenses that vary with occupancy for purposes hereof shall be determined as if the
Property had been ninety-five percent (95%) occupied and Landlord had been supplying services to ninety-five percent
(95%) of the Building Rentable Area during such year.

ARTICLE 10
INDEMNITY AND PUBLIC LIABILITY INSURANCE

10.1

Tenant’s Indemnity. Except to the extent arising from the gross negligence or willful misconduct of
Landlord or its agents or employees, Tenant shall defend with counsel first approved by Landlord, save harmless, and
indemnify Landlord and Landlord’s managing agent, beneficiaries, partners, members, shareholders, subsidiaries, officers,
directors, agents, trustees and employees (“Landlord Parties”) from and against all claims, losses, cost, damages, any
liability or expense of whatever nature arising from injury, loss, accident or damage to any person or property, arising from
or claimed to have arisen (a) from any accident, injury or damage whatsoever to any person, or to the property of any person,
occurring in the Premises; (b) from the negligent act or omission, or willful misconduct of Tenant or Tenant’s agents,
employees, contractors, licensees or invitees, or (c) in connection with Tenant’s use of the Premises or any business
conducted therein or any work done or condition created in the Premises by Tenant, its agent, employees or contractors, or
anyone claiming by, through or under Tenant and, in any case, occurring after the Commencement Date (or such earlier date
as of which Tenant takes possession of the Premises) until the expiration of the Term of this Lease and thereafter so long as
Tenant is in occupancy of any part of the Premises. This indemnity and hold harmless agreement shall include indemnity
against all losses, costs, damages, expenses and liabilities incurred in or in connection with any such claim or any
proceeding brought thereon, and the defense thereof, including, without limitation, reasonable attorneys’ fees and costs at
both the trial and appellate levels. The provisions of this Section 10.1 shall survive the expiration or earlier termination of
this Lease.

10.2

Tenant Insurance. Tenant shall, on or before the earlier of the Commencement Date or the date on which

Tenant first enters the Premises, obtain and keep in full force and effect at all times during the Term of this Lease the
following insurance coverages relating to the Premises:

(a)

Commercial General Liability. Insurance against loss or liability in connection with bodily injury,

death, or property damage or destruction, occurring on or about the Premises under one or more policies of commercial
general liability insurance. Each policy shall be written on an occurrence basis and contain coverage reasonably acceptable
to Landlord. Each policy shall specifically include the Premises. The insurance coverage shall be in an amount of at least the
limits set forth in Section 1.1 on a per location basis, with no deductible. Each policy shall also include the broad form
comprehensive general liability endorsement or equivalent and, in addition, shall provide at least the following extensions or
endorsements, if available: (1) [intentionally omitted]; (2) personal injury coverage to include liability assumed under any
contract; (3) a cross liability or severability of interest extension or endorsement or equivalent so that if one insured files a
claim against another insured under the policy, the policy

37

affords coverage for the insured against whom the claim is made as if separate policies had been issued; (4) a knowledge of
occurrence extension or endorsement so that knowledge of an occurrence by the agent, servant, or employee of the insured
shall not in itself constitute knowledge by the insured, unless a managing general partner or an executive officer, as the case
may be, shall have received the notice from the agent, servant, or employee; (5) a notice of occurrence extension or
endorsement so that if the insured reports the occurrence of an accident to its workers’ compensation carrier and the
occurrence later develops into a liability claim, the failure to report the occurrence immediately to each or any other
company when reported to the workers’ compensation carrier shall not be deemed a violation of the other company’s policy
conditions; (6) an unintentional errors and omissions extension or endorsement so that failure of the insured to disclose
hazards existing as of the inception date of the policy shall not prejudice the insured as to the coverage afforded by the
policy, provided the failure or omission is not intentional; and (7) a blanket additional insured extension or endorsement or
equivalent providing coverage for unspecified additional parties as their interest may appear with the insured.

(b)

(c)

Hazardous Materials.  Intentionally Omitted.

cover 100% of the replacement costs, without co-insurance, of Tenant’s personal property and trade fixtures, as well as all
tenant improvements located from time to time in the Premises, whether made by or on behalf of Tenant or otherwise
existing in the Premises as of the Commencement Date (such tenant improvements (collectively the “Improvements”) and
Alterations, whether provided or performed by or through Landlord or Tenant.

(e)

(f)

Business Interruption. Business income and extra expense insurance covering the risks to be insured

by the special coverage/all risk property insurance described above, on an actual loss sustained basis for a period of at least
twelve (12) months, but in all events in an amount sufficient to prevent Tenant from being a coinsurer of any loss covered
under the applicable policy or policies.

38

(g)

Other Insurance. Such other insurance as may be carried on the Premises and Tenant’s operation of

the Premises, as may be reasonably required by Landlord.

(h)

damage); (4) liability assumed under contract (on a broad form property damage basis); (5) liability assumed under contract
(on a broad form blanket basis); (6) explosion, collapse, and underground damage hazards, when applicable; and (7)

INCLUDE AN ENDORSEMENT PROVIDING THAT LANDLORD SHALL RECEIVE THIRTY (30) DAYS’ PRIOR
WRITTEN NOTICE OF ANY CANCELLATION, NONRENEWAL OR REDUCTION OF COVERAGE (EXCEPT THAT

PREMIUM). Regardless of carrier/agent notification to Landlord, Tenant shall provide Landlord with at least ten (10) days
prior notice of any policy cancellation or material reduction in coverage limits or coverage amounts, with respect to any
policy required of Tenant under this Lease. The minimum limits of insurance specified in this Section 13.3 shall in no way

evidence of payment of all premiums and other expenses owed in connection with

39

the policies. Any minimum amount of coverage specified in this Section 10.2 shall be subject to increase at any time after

increased, Tenant shall furnish Landlord with evidence of the increased coverage.

10.3

Tenant’s Risk. Tenant agrees to use and occupy the Premises and to use such other portions of the Property
as Tenant is herein given the right to use at Tenant’s own risk. Landlord shall not be liable to Tenant, its employees, agents,
invitees or contractors for any damage, injury, loss, compensation, or claim (including, but not limited to, claims for the
interruption of or loss to Tenant’s business) based on, arising out of or resulting from any cause whatsoever, including, but
not limited to, repairs to any portion of the Premises or the Property, any fire, robbery, theft, mysterious disappearance
and/or any other crime or casualty, the actions of any other tenants of the Building or of any other person or persons, or any
leakage in any part or portion of the Premises or the Building, or from water, rain or snow that may leak into, or flow from
any part of the Premises or the Building, or from drains, pipes or plumbing fixtures in the Building, unless due to the gross
negligence or willful misconduct of Landlord or Landlord’s agents, contractors or employees. Any goods, property or
personal effects stored or placed in or about the Premises shall be at the sole risk of Tenant, and neither Landlord nor
Landlord’s insurers shall in any manner be held responsible therefor. Landlord shall not be responsible or liable to Tenant, or
to those claiming by, through or under Tenant, for any loss or damage that may be occasioned by or through the acts or
omissions of persons occupying adjoining premises or any part of the premises adjacent to or connecting with the Premises
or any part of the Property or otherwise. Notwithstanding the foregoing, Landlord shall not be released from liability for any
injury, loss, damages or liability to the extent arising from any gross negligence or willful misconduct of Landlord, its
servants, employees or agents acting within the scope of their authority on or about the Premises; provided, however, that in
no event shall Landlord, its servants, employees or agents have any liability to Tenant based on any loss with respect to or
interruption in the operation of Tenant’s business except as expressly set forth below. The provisions of this Section 10.3
shall be applicable from and after the execution of this Lease and until the end of the Term of this Lease, and during any
additional period as Tenant may use or be in occupancy of any part of the Premises or of the Building.

10.4

Landlord’s Insurance. Landlord shall maintain, as a part of Operating Expenses, special form property
insurance on the Building in such amounts and subject to such deductibles as Landlord may reasonably determine. Such
insurance shall be maintained with an insurance company selected by Landlord or a Superior Mortgagee, and payment for
losses thereunder shall be made solely to Landlord subject to the rights of the Superior Mortgagee from time to time.
Additionally Landlord may maintain such additional insurance, including, without limitation, earthquake insurance,
terrorism insurance, flood insurance, liability insurance and/or rent insurance, as Landlord may in its sole discretion elect.
The cost of all such additional insurance shall also be part of the Operating Expenses. Any or all of Landlord’s insurance
may be provided by blanket coverage maintained by Landlord or any affiliate of Landlord under its insurance program for its
portfolio of properties or (except for property insurance) by Landlord’s or any affiliate of Landlord’s program of self
insurance, and in such event Operating Expenses shall include the portion of the reasonable cost of blanket insurance that is
allocated to the Building.

40

10.5 Waiver of Subrogation. Notwithstanding anything herein to the contrary, Landlord and Tenant each hereby

waives any and all rights of recovery, claim, action, or cause of action against the other, its agents, employees, licensees, or
invitees for any loss or damage to or at the Premises or the Property or any personal property of such party therein or thereon
by reason of fire, the elements, or any other cause which is covered, or would have been covered, by the insurance coverages
required to be maintained by Landlord and Tenant, respectively, under this Lease, regardless of cause or origin, including
omission of the other party hereto, its agents, employees, licensees, or invitees. Landlord and Tenant covenant that no insurer
shall hold any right of subrogation against either of such parties with respect thereto. The parties hereto agree that any and
all such insurance policies required to be carried by either shall be endorsed with a subrogation clause, substantially as
follows: “This insurance shall not be invalidated should the insured waive, in writing prior to a loss, any and all right of
recovery against any party for loss occurring to the Property described therein,” and shall provide that such party’s insurer
waives any right of recovery against the other party in connection with any such loss or damage.

ARTICLE 11
FIRE, EMINENT DOMAIN, ETC.

11.1

Landlord’s Right of Termination. If the Premises or the Building are substantially damaged (the term
“substantially damaged” meaning damage of such a character that the same cannot, in the ordinary course, reasonably be
expected to be repaired within one hundred eighty (180) days from the time that repair work would commence) by fire or
other casualty (each, a “Casualty”), then Landlord shall have the right to terminate this Lease by giving written notice of
Landlord’s election so to do within ninety (90) days after the occurrence of such Casualty, whereupon this Lease shall
terminate thirty (30) days after the date of such notice with the same force and effect as if such date were the date originally
established as the expiration date hereof. In no event shall Landlord have any liability for damages to Tenant for
inconvenience, annoyance or interruption of business arising from any Casualty.

11.2

Restoration; Tenant’s Right of Termination

(a)

If the Building or the Premises shall be partially or totally damaged or destroyed by a Casualty and
if this Lease is not terminated as provided in this Article 11, then (i) Landlord shall repair and restore the Building and the
Premises (but excluding Tenant’s Removable Property, Alterations, and the Landlord’s Work (“Landlord’s Restoration
Work”)) with reasonable dispatch (but Landlord shall not be required to perform the same on an overtime or premium pay
basis) after notice to Landlord of the Casualty and the collection of the insurance proceeds attributable to such Casualty, and
(ii) Tenant shall repair and restore in accordance with Section 5.2 all of Tenant’s Removable Property and the Improvements
(“Tenant’s Restoration Work”) with reasonable dispatch after the Casualty, subject to Tenant’s rights to modify the same.
Notwithstanding anything to the contrary contained herein, if in Landlord’s reasonable discretion it would be appropriate for
safety reasons, health reasons or the efficient operation or restoration of the Premises for Landlord to perform all or a portion
of Tenant’s Restoration Work on behalf of Tenant, then, subject to reasonable coordination between Landlord and Tenant and
the approval of Tenant’s insurer as required, (x) Landlord shall give Tenant a written notice specifying the portion of
Tenant’s Restoration Work to be performed by Landlord (the

41

“Specified Restoration Work”), (y) Landlord shall perform the Specified Restoration Work, and (z) Tenant shall make
available to Landlord out of insurance proceeds received by Tenant the cost of such Specified Restoration Work as such
work progresses, plus such additional out of pocket amounts as are reasonably required to complete the Specified
Restoration Work.

(b)

If all or part of the Premises is damaged or destroyed by a Casualty, and neither party elects to

exercise its termination right under this Article 11 (or if no such termination rights are triggered), Landlord may, by written
notice to Tenant given within thirty (30) days after the date of such Casualty, relocate Tenant to available space in the
Building which is comparable to the Premises, including without limitation in fit, finish and level of improvement (the
“Interim Space”) during the restoration of the Premises, provided (i) Landlord shall pay the reasonable and actual costs to
move Tenant’s moveable fixtures, furniture and equipment into the Interim Space, and back into the Premises after
restoration, (ii) the square footage of the Interim Space shall not be less than the Premises Rentable Area, (iii) the Interim
Space shall be suitable for the conduct and operation of Tenant’s business as determined by Tenant in its good faith
discretion, (iv) Tenant’s business is not interrupted or adversely affected on account of any such relocation to Interim Space,
(v) Tenant does not incur any costs on account of such relocation to Interim Space unless Landlord reimburses Tenant for the
same, and (vi) upon occupancy of the Interim Space, Tenant shall pay Landlord Rent for the Interim Space at the same per
square foot rental rate as is then applicable under this Lease, adjusted to reflect the actual square footage of the Interim
Space (but which Rent shall not exceed the Rent for the Premises). If Landlord exercises the foregoing option, Tenant shall
relocate from the Premises to the Interim Space within thirty (30) days after delivery of such Interim Premises in the
condition required by this paragraph; and Tenant shall relocate from the Interim Space to the restored Premises within thirty
(30) days after restoration of the Premises, the Landlord’s Work, and any Alterations have been substantially completed by
Landlord and Tenant in accordance with this Section 11.2.

(c)

Landlord shall not carry any insurance on Tenant’s Removable Property, the Landlord’s Work or on

Alterations that constitute part of Tenant’s Restoration Work and shall not be obligated to repair or replace Tenant’s
Removable Property or such Landlord’s Work and Alterations (whether or not installed by or at the expense of Landlord).
Tenant shall look solely to its insurance for recovery of any damage to or loss of Tenant’s Removable Property and any
Landlord’s Work and Alterations. Tenant shall notify Landlord promptly of any casualty in the Premises. In the event of a
partial or total destruction of the Premises, Tenant shall as soon as practicable (but no later than ten (10) Business Days after
receiving a notice from Landlord) remove any and all of Tenant’s Removable Property from the Premises or the portion
thereof destroyed, as the case may be, and if Tenant does not promptly so remove Tenant’s Removable Property, Landlord, at
Tenant’s expense, may remove Tenant’s Removable Property to a bonded public warehouse for storage with at least three (3)
Business Days’ prior written notice to Tenant. Tenant shall be solely responsible for arranging for any visits to the Premises
by Tenant’s insurance adjuster that may be desired by Tenant prior to the removal of Tenant’s Removable Property by
Tenant, or the performance by Landlord of Landlord’s Restoration Work or the Specified Restoration Work and Landlord
shall be under no obligation to delay the performance of same, nor shall Landlord have any liability to Tenant in the event
that Tenant fails to do so. Tenant shall promptly permit Landlord access to the Premises for the purpose of performing
Landlord’s Restoration Work .

42

(d)

Within ninety (90) days after the occurrence of any Casualty affecting the Premises or the common

areas necessary for the use and enjoyment of the same, Landlord shall deliver to Tenant a written estimate (“Landlord’s
Estimate”) from a reputable contractor designated by Landlord as to the probable length of time that will be necessary to
substantially complete Landlord’s Restoration Work. If such time estimate exceeds 180 days from the date that repair work
would commence, Tenant shall have the right to terminate this Lease by giving written notice to Landlord thereof within
thirty (30) days after receipt of such estimate (time being of the essence with respect to the giving of such notice by Tenant).
If Tenant is entitled pursuant to the terms of this Section 11.2(d) to terminate this Lease and Tenant fails to deliver a
termination notice to Landlord within the thirty (30) day period set forth herein, Tenant will be deemed to have waived
Tenant’s rights under this Section 11.2(d) to terminate the Lease on account of such Casualty. The provisions of this Section
are in lieu of any statutory termination provisions allowable in the event of a Casualty. Furthermore, if Landlord has not
substantially completed the Landlord’s Restoration Work within the time set forth in the Landlord’s Estimate, then Tenant
shall have the right to terminate this Lease by written notice given within 30 days following the expiration of such period.

(e)

If this Lease is terminated under any of the provisions of this Article XI as a result of a Casualty,

Landlord shall be entitled to retain for its benefit the proceeds of insurance maintained by Tenant on the Landlord’s Work in
an amount not to exceed the unamortized cost of the Landlord’s Work, amortized over the initial term of the Lease. This
Section 11.2 shall be deemed an express agreement governing any damage or destruction of the Premises by fire or other
casualty, and any law providing for a contingency in the absence of an express agreement, now or hereafter in force, shall
have no application.

11.3

Abatement of Rent. If the Premises is damaged by a Casualty, Basic Rent and Escalation Charges payable

by Tenant shall abate proportionately for the period from the date of such fire or other casualty until the earlier of (a) the date
that Landlord substantially completes Landlord’s Restoration Work (provided that if Landlord would have completed
Landlord’s Restoration Work at an earlier date but for Tenant having failed to cooperate with Landlord in effecting such
Work or collecting insurance proceeds, following notice from Landlord of such failure and the passage of 10 days without
Tenant curing such failure, then the Premises shall be deemed to have been repaired and restored on such earlier date and the
abatement shall cease) plus a period of four months, or (b) the date Tenant or other occupant reoccupies any portion of the
Premises for the conduct of its business as opposed to the completion of Tenant’s restoration obligations (in which case the
Basic Rent and Escalation Charges allocable to such reoccupied portion shall be payable by Tenant from the date of such
occupancy). Notwithstanding any provision contained in this Lease to the contrary, (i) there shall be no abatement with
respect to any portion of the Premises which has not been rendered untenantable for Tenant’s particular use by reason of fire
or other casualty and which is accessible, whether or not other portions of the Premises are untenantable, and (ii) any
abatement of Basic Rent or Escalation Charges applicable to any portion of the Premises which was rendered untenantable
by reason of a casualty shall cease on the earliest of the dates referred to in clauses (a) or (b) of the preceding sentence
provided such portion is accessible, whether or not other portions of the Premises remain untenantable. Landlord’s
determination of the date Landlord’s Restoration Work to the Premises shall have been substantially completed shall be
controlling unless Tenant disputes same by notice to Landlord given within ten (10) days after such determination by
Landlord, and pending

43

resolution of such dispute, Tenant shall pay Basic Rent and Escalation Charges in accordance with Landlord’s determination.
Notwithstanding the foregoing, if by reason of any act or omission by Tenant, any subtenant or any of their respective
partners, directors, officers, servants, employees, agents or contractors, Landlord or any Mortgagee shall be unable to collect
all of the insurance proceeds (including, without limitation, rent insurance proceeds) applicable to the casualty, following
notice from Landlord and Tenant’s failure to cure the same within 10 days, then, without prejudice to any other remedies
which may be available against Tenant, there shall be no abatement of Basic Rent or of Escalation Charges.

11.4

Eminent Domain

(a)

If the Premises shall be taken by any exercise of the power of eminent domain, Basic Rent and

Escalation Charges payable by Tenant shall be justly and equitably abated and reduced according to the nature and extent of
the loss of use thereof suffered by Tenant. In no event shall Landlord have any liability for damages to Tenant for
inconvenience, annoyance or interruption of business arising from such exercise of the power of eminent domain.

(b)

If any part of the Building is taken by any exercise of the right of eminent domain, then Landlord
shall have the right to terminate this Lease (even if Landlord’s entire interest in the Premises may have been divested) by
giving notice of Landlord’s election so to do within ninety (90) days after the occurrence of the effective date of such taking,
whereupon this Lease shall terminate thirty (30) days after the date of such notice with the same force and effect as if such
date were the date originally established for the expiration of the Term of this Lease. If any material portion of the Premises
is rendered permanently untenantable for Tenant’s particular business on account of any such right of eminent domain, then
Tenant shall have the right to terminate this Lease upon 30 days’ prior notice to Landlord given with ninety (90) days after
the occurrence of the effective date of such taking.

(c)

If this Lease shall not be terminated pursuant to Section 11.4(b), Landlord shall thereafter use due

diligence to restore the affected areas of the Building and Premises (excluding any Tenant’s Removable Property installed by
Tenant pursuant to Section 5.2) to proper condition for Tenant’s use and occupation, provided that Landlord’s obligation
shall be limited to the amount of compensation recoverable by Landlord from the taking authority. If, for any reason, such
restoration shall not be substantially completed within six (6) months after the expiration of the ninety (90) day period
referred to in Section 11.4(b) (which six month period may be extended for such periods of time as Landlord is prevented
from proceeding with or completing such restoration for any cause beyond Landlord’s reasonable control, but in no event for
more than an additional three (3) months), Tenant shall have the right to terminate this Lease by giving notice to Landlord
thereof within thirty (30) days after the expiration of such period (as so extended). Upon the giving of such notice, this Lease
shall cease and come to an end thirty (30) days after the giving of such notice, without further liability or obligation on the
part of either party unless, within such thirty (30) day period, Landlord substantially completes such restoration. Such right
of termination shall be Tenant’s sole and exclusive remedy at law or in equity for Landlord’s failure so to complete such
restoration.

44

(d)

Landlord shall have and hereby reserves and excepts, and Tenant hereby grants and assigns to

Landlord, all rights to recover for damages to the Property and the leasehold interest hereby created (including any
Alterations made by Tenant pursuant to Section 5.2, but excluding any of Tenant’s Removable Property), and to
compensation accrued or hereafter to accrue by reason of such taking, and by way of confirming the foregoing, Tenant
hereby grants and assigns, and covenants with Landlord to grant and assign to Landlord, all rights to such damages or
compensation, and covenants to deliver such further assignments and assurances thereof as Landlord may from time to time
request, and Tenant hereby irrevocably appoints Landlord its attorney in fact to execute and deliver in Tenant’s name all such
assignments and assurances. Nothing contained herein shall be construed to prevent Tenant from prosecuting in any
condemnation proceedings a claim for the value of any of Tenant’s Removable Property installed in the Premises by Tenant
at Tenant’s expense and for relocation expenses, provided that such action shall not affect the amount of compensation
otherwise recoverable by Landlord from the taking authority.

ARTICLE 12
HOLDING OVER; SURRENDER

12.1 Holding Over. If Tenant or anyone claiming by, through or under Tenant shall remain in possession of all or
any part of the Premises (which shall include a failure by Tenant to remove any Tenant’s Removable Property or Alterations
which Landlord notified Tenant were to be removed at the expiration or earlier termination of the Term) after the expiration
or earlier termination of the Term of this Lease, such holding over shall be treated as a daily tenancy at sufferance at a Basic
Rent equal to one hundred fifty percent (150%) for the first 30 days and two hundred percent (200%) thereafter of the Basic
Rent in effect for the last rental period of the Term, plus Escalation Charges and other Additional Rent herein provided
(prorated on a daily basis). In addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend,
indemnify and hold Landlord harmless from all loss, costs and damages, direct and/or indirect, sustained by reason of any
such holding over in excess of 30 days, including, without limitation, claims made by and loss of any succeeding tenant
arising out of such failure to timely surrender possession in the condition required under this Lease. In all other respects,
such holding over shall be on the terms and conditions set forth in this Lease as far as applicable (and excluding any
extension, expansion or rights of first offer of tenant) in the Lease. Nothing contained in this Article 12 shall be construed as
a consent by Landlord to any holding over by Tenant, and Landlord shall have the right to immediately terminate such
holding over pursuant to applicable Law. The provisions of this Article 12 shall not be deemed to limit or constitute a waiver
of any other rights or remedies of Landlord provided herein or at law.

12.2

Surrender of Premises.

(a)

At least thirty (30) days prior to Tenant’s surrender of possession of any part of the Premises, Tenant

shall provide Landlord with a facility decommissioning and Hazardous Materials closure plan for the Premises with respect
to Hazardous Materials used by Tenant or any Tenant Party at the Premises during the term of this Lease (“Exit Survey”)
prepared by an independent third party state-certified professional with appropriate expertise, which Exit Survey must be
reasonably acceptable to Landlord. The Exit Survey shall comply

45

with the American National Standards Institute’s Laboratory Decommissioning guidelines (ANSI/AIHA Z9.11-2008) or any
successor standards published by ANSI or any successor organization (or, if ANSI and its successors no longer exist, a
similar entity publishing similar standards). In addition, at least ten (10) days prior to Tenant’s surrender of possession of any
part of the Premises, Tenant shall (i) provide Landlord with written evidence of all appropriate governmental releases related
to Tenant’s operation at the Premises, to the extent such releases are necessary for the re-occupancy of the same or otherwise
if required by Landlord, obtained by Tenant in accordance with applicable Laws, including laws pertaining to the surrender
of the Premises, (ii) place Laboratory Equipment Decontamination Forms on all decommissioned equipment to assure safe
occupancy by future users and (ii) conduct a site inspection with Landlord. In addition, Tenant agrees to remain responsible
after the surrender of the Premises for the remediation of any recognized environmental conditions set forth in the Exit
Survey for which Tenant is responsible under this Lease and comply with any recommendations set forth in the Exit Survey.
Tenant’s obligations under this Section shall survive the expiration or earlier termination of the Lease.

(b)

In addition to the foregoing requirement, upon the expiration or earlier termination of the Term of

this Lease, Tenant shall promptly and peaceably quit and surrender to Landlord the Premises in neat and clean condition and
in good order, condition and repair, excepting only ordinary wear and use and damage by fire or other casualty or
condemnation for which, under other provisions of this Lease, Tenant has no responsibility to repair or restore together with
all Alterations which may have been made or installed in, on or to the Premises prior to or during the Term of this Lease
(except as otherwise required by Landlord pursuant to Section 5.2(e) above), and all attached equipment, decorations,
fixtures, laboratory casework, non-movable trade fixtures, and Alterations built into the Premises (including Landlord’s
Work) made by either of the parties (including all floor and wall coverings; paneling; sinks and related plumbing fixtures;
immovable laboratory benches; exterior venting fume hoods; walk-in freezers and refrigerators; ductwork; conduits;
electrical panels and circuits; attached, non -movable business and trade fixtures; attached, non-movable machinery and
equipment; and built-in furniture and cabinets, in each case, together with all additions thereto). Tenant shall remove all of
Tenant’s Removable Property, all signs installed by Tenant in or on the Premises and the Building, all lines and other wiring
and cabling installed by Tenant prior to or during the Term. No Landlord’s Work shall be considered Tenant’s Removable
Property (whether or not the same is movable). For the avoidance of doubt, the items listed on Exhibit G attached hereto
(which Exhibit G may be updated by Tenant from and after the Commencement Date, subject to Landlord’s written consent
provided that such consent shall not be unreasonably withheld, conditioned or delayed with respect to items purchased and
brought onto the Premises by Tenant after the Commencement Date) constitute Tenant’s Removable Property and shall be
removed by Tenant upon the expiration or earlier termination of the Lease, and no Landlord’s Work shall be considered
Tenant’s Removable Property (whether or not the same is movable).

(c)

Tenant shall repair any damage to the Premises or the Building caused by such removal and restore

the affected area to its condition prior to the installation thereof. Any Tenant’s Removable Property which shall remain in the
Building or on the Premises after the expiration or termination of the Term of this Lease shall, if not removed within 10 days
after notice by Landlord, be deemed conclusively to have been abandoned, and either may be retained

46

by Landlord as its property or may be disposed of in such manner as Landlord may see fit, at Tenant’s sole cost and expense.

ARTICLE 13
RIGHTS OF MORTGAGEES; TRANSFER OF TITLE

13.1

Rights of Mortgagees or Ground Lessor.

(a)

This Lease, and all rights of Tenant hereunder, are and shall be subject and subordinate to any

ground or underlying leases of the Property and to all renewals, extensions, modifications and replacements thereof, and to
the lien of all mortgages, deeds of trust or similar encumbrances which may now or hereafter affect the Property, whether or
not such mortgages or other encumbrances shall also cover other lands and/or buildings, and to each and every advance
made or hereafter to be made under such mortgages and other encumbrances, and to all renewals, modifications,
replacements, extensions and consolidations of such mortgages and other encumbrances; provided that so long as an Event
of Default does not then exist, as a condition to the foregoing, such future mortgagees or other holders enter into a
commercially reasonable non-disturbance and recognition agreement that recognizes Tenant as a direct tenant on all of the
terms hereunder. This Section shall be self operative and no further instrument of subordination shall be required. In
confirmation of such subordination, Tenant shall promptly execute, acknowledge and deliver any commercially reasonable
instrument that Landlord, the lessor under any such lease or the holder of any such mortgage or other encumbrance or any of
their respective successors in interest may reasonably request to evidence such subordination. Any lease to which this Lease
is, at the time referred to, subject and subordinate is herein called “Superior Lease” and the lessor of a Superior Lease or its
successor in interest at the time referred to, is herein called “Superior Lessor”; and any mortgage or other encumbrance to
which this Lease is, at the time referred to, subject and subordinate, is herein called “Superior Mortgage” and the holder of
a Superior Mortgage, or its successor in interest at the time referred to, is herein called “Superior Mortgagee.” If any
Superior Mortgagee, shall so elect, this Lease and the rights of Tenant hereunder, shall be superior in right to the rights of
such holder, with the same force and effect as if this Lease had been executed, delivered and recorded, or a statutory notice
hereof recorded, prior to the execution, delivery and recording of any such Superior Mortgage. The election of any such
Superior Mortgagee shall become effective upon either notice from such Superior Mortgagee to Tenant in the same fashion
as notices from Landlord to Tenant are to be given hereunder or by the recording in the appropriate registry or recorder’s
office of an instrument in which the Superior Mortgagee subordinates its rights under such Superior Mortgage to this Lease.
At Tenant’s cost and expense, including without limitation, any costs of Superior Mortgagee for which Landlord is obligated
to pay, Landlord shall use commercially reasonable efforts to obtain an SNDA for the benefit of Tenant from any Superior
Mortgagee existing as of the Effective Date, but failure to do so shall not be deemed to be a default of Landlord.

(b)

If any Superior Lessor or Superior Mortgagee or the nominee or designee of any Superior Lessor or

Superior Mortgagee shall succeed to the rights of Landlord under this Lease, whether through possession or foreclosure
action or delivery of a new lease or deed, or otherwise, then at the request of such party so succeeding to Landlord’s rights
(herein called

47

“Successor Landlord”), Tenant shall attorn to and recognize such Successor Landlord as Tenant’s landlord under this Lease
and shall promptly execute and deliver any commercially reasonable instrument that such Successor Landlord may
reasonably request to evidence such attornment. Tenant waives the provisions of any law or regulation, now or hereafter in
effect, which terminates or may give or purport to give Tenant any right to terminate or otherwise affect this Lease or the
obligations of Tenant hereunder in the event that any such foreclosure, termination or other proceeding is filed, prosecuted or
completed. Upon such attornment, this Lease shall continue in full force and effect as a direct lease between the Successor
Landlord and Tenant upon all of the terms, conditions and covenants as are set forth in this Lease, except that (subject to the
terms of any SNDA between Tenant and such successor) the Successor Landlord shall not be (i) liable in any way to Tenant
for any act or omission, neglect or default on the part of Landlord under this Lease, (ii) responsible for any monies owing by
or on deposit with Landlord to the credit of Tenant, (iii) subject to any counterclaim or setoff which theretofore accrued to
Tenant against Landlord (other than setoffs expressly permitted under this Lease), (iv) bound by any modification of this
Lease subsequent to such Superior Lease or Superior Mortgage, or by any previous prepayment of fixed rent for more than
one (1) month in advance of the date due, which was not approved in writing by the Superior Lessor or the Superior
Mortgagee thereto, (v) liable to the Tenant beyond the Successor Landlord’s interest in the Property and the rents, income,
receipts, revenues, issues and profits issuing from such Property, (vi) responsible for the performance of any work to be done
by the Landlord under this Lease to render the Premises ready for occupancy by the Tenant, (vii) liable for the payment of
any improvement allowance or similar amount owing to Tenant on account of the performance of any alterations or
leasehold improvements to the Premises or the Building, or (b) required to remove any person occupying the Premises or
any part thereof, except if such person claims by, through or under the Successor Landlord.

13.2

Assignment of Rents and Transfer of Title.

(a)

With reference to any assignment by Landlord of Landlord’s interest in this Lease, or the rents

payable hereunder, conditional in nature or otherwise, which assignment is made to a Superior Mortgagee on property which
includes the Premises, Tenant agrees that the execution thereof by Landlord, and the acceptance thereof by the Superior
Mortgagee shall never be treated as an assumption by the Superior Mortgagee of any of the obligations of Landlord
hereunder unless the Superior Mortgagee shall, by notice sent to Tenant, specifically otherwise elect and, except as
aforesaid, the Superior Mortgagee shall be treated as having assumed Landlord’s obligations hereunder only upon
foreclosure of the Superior Mortgage and the taking of possession of the Premises.

(b)

In no event shall the acquisition of Landlord’s interest in the Property by a purchaser which,

simultaneously therewith, leases Landlord’s entire interest in the Property back to the seller thereof be treated as an
assumption by operation of law or otherwise, of Landlord’s obligations hereunder, but Tenant shall look solely to such seller-
lessee, and its successors from time to time in title, for performance of Landlord’s obligations hereunder, to the extent such
seller-lessee has assumed the obligations under this Lease. In any such event, this Lease shall be subject and subordinate to
the lease to such purchaser subject to the provisions of this Section 13.2(b). For all purposes, such seller-lessee, and its
successors in title, shall be the Landlord

48

hereunder unless and until Landlord’s position shall have been assumed by such purchaser-lessor.

(c)

Except as provided in paragraph (b) of this Section, in the event of any transfer of title to the

Property by Landlord, Landlord shall thereafter be entirely freed and relieved from the performance and observance of all
covenants and obligations hereunder except with respect to monetary obligations owed by Landlord to Tenant to the extent
the same accrued prior to the date of such transfer.

13.3

Notice to Mortgagee. Tenant shall not seek to enforce any remedy it may have for any default on the part of

Landlord (other than those remedies expressly set forth in Section 7.6(b)) without first giving any Superior Mortgagee and
Superior Lessor, as applicable, of which Tenant has prior notice written notice by certified mail, return receipt requested,
specifying the default in reasonable detail, and affording such Superior Mortgagee and Superior Lessor, as applicable, (i) a
reasonable opportunity to perform Landlord’s obligations hereunder (but not less than thirty (30) days), if such default can
be cured without such Superior Mortgagee or Superior Lessor, as applicable, taking possession of the mortgaged or leased
estate, or (ii) time to obtain possession of the mortgaged or leased estate and then to cure such default of Landlord, if such
default cannot be cured without such Superior Mortgagee or Superior Lessor or taking possession of the mortgaged or leased
estate. The curing of any of Landlord’s defaults by a Superior Mortgagee or Superior Lessor shall be treated as performance
by Landlord.

ARTICLE 14
DEFAULT; REMEDIES

14.1

Tenant’s Default.

(a)

If at any time subsequent to the date of this Lease any one or more of the following events (herein

referred to as an “Event of Default”) shall occur:

(i)

Tenant shall fail to pay the Basic Rent, Escalation Charges or any other Additional Rent

hereunder when due and such failure shall continue for three (3) Business Days after written notice to
Tenant from Landlord (except that such written notice shall only be required once in any twelve (12) month
period with respect to Basic Rent or any Escalation Charges, with any subsequent failure to pay such sums
constituting an Event of Default unless paid within three (3) Business Days after the date due without need
for an additional written notice); or

(ii)

(ii)

Tenant shall neglect or fail to perform or observe any other covenant herein

contained on Tenant’s part to be performed or observed and Tenant shall fail to remedy the same within
thirty (30) days after notice to Tenant (or such shorter period for completing a cure for such default as may
be required by applicable Laws or by virtue of an emergency situation) specifying such neglect or failure, or
if such failure is of such a nature that Tenant cannot reasonably remedy the same within such thirty (30) day
period, Tenant shall fail to commence promptly (and in any event within such thirty (30) day period) to

49

remedy the same and thereafter to diligently prosecute such remedy to completion with diligence and
continuity (and in any event, within ninety (90) days after the notice described in this subparagraph (ii)),
provided that (x) in no event shall Tenant have such additional period of time that would (A) subject
Landlord or any Superior Lessor or any Superior Mortgagee to prosecution for a crime or any other fine or
charge, or (B) subject the Property, or any part thereof, to any lien or encumbrance which is not removed or
bonded within the time period required under this Lease or

(iii)

Tenant’s leasehold interest in the Premises shall be taken on execution or by other process

of law directed against Tenant; or

(iv)

If Tenant or any guarantor of this Lease shall (i) make an assignment for the benefit of

creditors, (ii) acquiesce in a petition in any court in any bankruptcy, reorganization, composition, extension
or insolvency proceedings, (iii) seek, consent to or acquiesce in the appointment of any trustee, receiver or
liquidator of Tenant or of any guarantor of this Lease or of all or any part of Tenant’s or such guarantor’s
property, (iv) file a petition seeking an order for relief under the Title 11 of the United States Code, as now
or hereafter amended or supplemented (the “Bankruptcy Code”), or by filing any petition under any other
present or future federal, state or other statute or law for the same or similar relief, or (v) fail to win the
dismissal, discontinuation or vacating of any involuntary bankruptcy proceeding filed under the Bankruptcy
Code, or under any other present or future federal, state or other statute or law for the same or similar relief,
within ninety (90) days after such proceeding is initiated; or

(v)

Any lien has been filed against the Property, or any portion thereof, as a result of Tenant’s
acts, omissions or breach of this Lease, and Tenant fails, within 30 days after the lien is filed, either (1) to
cause said lien to be removed from the Property, or (2) to furnish a bond sufficient to remove the lien or
cause a title insurance endorsement to be issued with respect to such lien, which endorsement shall be
satisfactory, in form and substance to Landlord, in Landlord’s sole discretion; then in any such case
Landlord may exercise any of Landlord’s rights or remedies available under this Lease, at law or in equity.

14.2

Landlord’s Remedies.

(a)

During the continuance of an Event of Default, Landlord shall have the following remedies, in

addition to any and all other rights and remedies available at Law or in equity or otherwise provided in this Lease, any one
or more of which Landlord may resort to cumulatively, consecutively, or in the alternative:

(i)

Landlord may continue this Lease in full force and effect, and collect Rent and other

charges as and when due, without prejudice to Landlord’s

50

right to subsequently elect to terminate this Lease on account of such Event of Default;

(ii)

Landlord may terminate this Lease upon written notice to Tenant to such effect, in which
event this Lease (and all of Tenant’s rights hereunder) shall immediately terminate, but such termination
shall not affect those obligations of Tenant which are intended by their terms to survive the expiration or
termination of this Lease, and Tenant shall remain liable for damages as hereinafter set forth in this Section
14.2. This Lease may also be terminated by a judgment specifically providing for termination;

(iii)

Landlord may terminate Tenant’s right of possession without terminating this Lease upon

written notice to Tenant to such effect, in which event Tenant’s right of possession of the Premises shall
immediately terminate, but this Lease shall continue subject to the effect of this Section 14.2;

(iv)

Landlord may, but shall not be obligated to, perform any defaulted obligation of Tenant, and

to recover from Tenant, as Additional Rent, the costs incurred by Landlord in performing such obligation.
Notwithstanding the foregoing, or any other notice and cure period set forth herein, Landlord may exercise
its rights under this Section 14.2(a)(iv) without prior notice or upon shorter notice than otherwise required
hereunder (and as may be reasonable under the circumstances) in the event of any one or more of the
following circumstances is present: (i) there exists a reasonable risk of prosecution of Landlord under
applicable Law unless such obligation is performed sooner than the stated cure period; (ii) there exists an
emergency arising out of the defaulted obligation; or (iii) the Tenant has failed to obtain insurance required
by this Lease, or such insurance has been canceled by the insurer without being timely replaced by Tenant,
as required herein; and

(v)

Landlord shall have the right to recover damages from Tenant, as set forth in this Section

14.2.

(b)

Upon any termination of this Lease or of Tenant’s right of possession, Landlord, at its sole election,

in compliance with applicable Law, may (i) re-enter the Premises, either by summary proceedings, ejectment or otherwise,
and remove and dispossess Tenant and all other persons and any and all property from the same, as if this Lease had not been
made, (ii) remove all property from the Premises and store the same in a public warehouse or elsewhere at Tenant’s expense,
and/or (iii) deem such property to be abandoned, and, in such event, Landlord may dispose of such property at Tenant’s
expense, free from any claim by Tenant or anyone claiming by, through or under Tenant. It shall not constitute a constructive
or other termination of this Lease or Tenant’s right to possession if Landlord (a) exercises its right to repair or maintain the
Premises, (b) performs any unperformed obligations of Tenant, (c) stores or removes Tenant’s property from the Premises
after Tenant’s dispossession, (d) attempts to relet, or, in fact, does relet, the Premises or (e) seeks the appointment of a
receiver on Landlord’s initiative to protect Landlord’s interest under this Lease.

51

(c)

If this Lease shall have been terminated as provided in this Article, Tenant shall pay the Basic Rent,

Escalation Charges, Additional Rent and other sums payable hereunder up to the time of such termination, and thereafter
Tenant, until the end of what would have been the Term of this Lease in the absence of such termination, and whether or not
the Premises shall have been relet, shall be liable to Landlord for, and shall pay to Landlord, as liquidated current damages:
the Basic Rent, Escalation Charges, Additional Rent and other sums that would be payable hereunder if such termination had
not occurred, less the net proceeds, if any, of any reletting of the Premises, after deducting all out of pocket expenses
incurred by Landlord in connection with such reletting, including, without limitation, all repossession costs, brokerage
commissions, legal expenses, reasonable attorneys’ fees, advertising, out of pocket expenses of employees, alteration costs
and expenses of preparation for such reletting. Tenant shall pay the portion of such current damages referred to in the
preceding sentence to Landlord monthly on the days which the Basic Rent would have been payable hereunder if this Lease
had not been terminated.

(d)

At any time after termination of this Lease as provided in this Article, whether or not Landlord shall
have collected any such current damages, as liquidated final damages and in lieu of all such current damages beyond the date
of such demand, at Landlord’s election Tenant shall pay to Landlord an amount equal to the excess, if any, of the Basic Rent,
Escalation Charges, Additional Rent and other sums as hereinbefore provided which would be payable hereunder from the
date of such demand assuming that, for the purposes of this paragraph, annual payments by Tenant on account of Taxes and
Operating Expenses would be the same as the payments required for the immediately preceding Operating or Tax Year plus a
three percent (3%) annual increase per year for what would be the then unexpired Term of this Lease if the same remained in
effect, over the then fair net rental value of the Premises for the same period.

(e)

In case of any Event of Default, re-entry, expiration and dispossession by summary proceedings or

otherwise, Landlord may (i) relet the Premises or any part or parts thereof, either in the name of Landlord or otherwise, for a
term or terms which may at Landlord’s option be equal to or less than or exceed the period which would otherwise have
constituted the balance of the Term of this Lease and may grant concessions or free rent to the extent that Landlord considers
advisable and necessary to re let the same and (ii) make such alterations, repairs and decorations in the Premises as Landlord
considers advisable and necessary for the purpose of reletting the Premises; and the making of such alterations, repairs and
decorations shall not operate or be construed to release Tenant from liability hereunder as aforesaid. Tenant, for itself and
any and all persons claiming through or under Tenant, including its creditors, upon the termination of this Lease and of the
term of this Lease in accordance with the terms hereof, or in the event of entry of judgment for the recovery of the
possession of the Premises in any action or proceeding, or if Landlord shall enter the Premises by process of law or
otherwise, hereby waives any right of redemption provided or permitted by any statute, law or decision now or hereafter in
force, and does hereby waive, surrender and give up all rights or privileges which it or they may or might have under and by
reason of any present or future law or decision, to redeem the Premises or for a continuation of this Lease for the term of this
Lease hereby demised after having been dispossessed or ejected therefrom by process of law, or otherwise.

52

(f)

In addition to any other remedies under this Article 14, Tenant shall be liable to Landlord for all
damages proximately caused by Tenant’s breach of its obligations under this Lease, including all costs Landlord incurs in
reletting (or attempting to relet) the Premises or any part thereof, including, without limitation, brokers’ commissions,
expenses of cleaning, altering and preparing the Premises for new tenants, legal fees and all other like expenses properly
chargeable against the Premises and the rental received therefrom and like costs, provided that nothing set forth in this
Section 14.2(f) shall be construed to impose upon Landlord any obligation to relet the Premises or to mitigate its damages
hereunder, except to the extent expressly required under applicable Law. If Landlord does elect to relet the Premises (or any
portion thereof), such reletting may be for a period shorter or longer than the remaining Term, and upon such terms and
conditions as Landlord deems appropriate, in its sole and absolute discretion, and Tenant shall have no interest in any sums
collected by Landlord in connection with such reletting except to the extent expressly set forth herein. If the Premises or any
part thereof shall be relet in combination with any other space, then proper apportionment on a per-square foot basis shall be
made of the rent received from such reletting and of the expenses of such reletting. If Landlord shall succeed in reletting the
Premises during the period in which Tenant is paying monthly rent damages as described in Section 14.2(c), Landlord shall
credit Tenant with the net rents collected by Landlord from such reletting, after first deducting from the gross rents, as and
when collected by Landlord, (A) all out of pocket expenses incurred or paid by Landlord in collecting such rents, and (B)
any theretofore unrecovered costs associated with the termination of this Lease or Landlord’s reentry into the Premises,
including any theretofore unrecovered expenses of reletting or other damages payable hereunder. If the Premises or any
portion thereof be relet by Landlord for the unexpired portion of the Term before presentation of proof of such damages to
any court, commission or tribunal, the amount of rent reserved upon such reletting shall, prima facie, constitute the fair and
reasonable rental value for the Premises, or part thereof, so relet for the term of the reletting. Landlord shall not be liable in
any way whatsoever for its failure or refusal to relet the Premises or, if the Premises or any part are relet, for its failure to
collect the rent under such reletting, and no such refusal or failure to relet or failure to collect rent shall release or affect
Tenant’s liability for damages or otherwise under this Lease.

(g)

If the trustee or the debtor in possession assumes the Lease under applicable bankruptcy law, it may

assume and assign its interest in this Lease only if the proposed assignee first provides Landlord with (1) notice of such
proposed assignment, setting forth (i) the name and address of the proposed assignee, its proposed use of the Premises,
reasonably detailed character and financial references for such person (including its most recent balance sheet and income
statements certified by its chief financial officer or, if available, a certified public accountant) and any other information
reasonably requested by Landlord, and (ii) all of the terms and conditions of such offer, shall be given to Landlord by Tenant
or such trustee no later than twenty (20) days after receipt by Tenant or such trustee of such offer, but in any event no later
than ten (10) days prior to the date that Tenant or such trustee shall make application to a court of competent jurisdiction for
authority and approval to assume this Lease and enter into such assignment; (2) Adequate Assurance of Future Performance
(as hereinafter defined) of all of Tenant’s obligations under this Lease, and (3) Landlord determines, in the exercise of its
reasonable business judgment, that the assignment of this Lease will not breach any other lease, or any mortgage, financing
agreement, or other agreement relating to the Property by which Landlord or the Property is then bound (and Landlord shall
not be required to

53

obtain consents or waivers from any third party required under any lease, mortgage, financing agreement, or other such
agreement by which Landlord is then bound). Landlord shall have the option, to be exercised by notice to Tenant or such
trustee given at any time prior to the date the application is filed for court approval of the assumption and assignment of this
Lease to the proposed assignee, to accept an assignment of this Lease upon the same terms and conditions and for the same
consideration, if any, as the bona fide offer made by such proposed assignee, less any brokerage commissions which may be
payable out of the consideration to be paid by such person for the assignment of this Lease.

(h)

For purposes only of paragraph (g) above, and in addition to any other requirements under the

Bankruptcy Code, any future federal bankruptcy law and applicable case law, “Adequate Assurance of Future Performance”
means at least the satisfaction of the following conditions, which Landlord and Tenant acknowledge to be commercially
reasonable:

(i)

the proposed assignee submitting a current financial statement, audited by a certified public

accountant, that allows a net worth and working capital in amounts determined in the reasonable business
judgment of Landlord to be sufficient to assure the future performance by the assignee of Tenant’s
obligation under this Lease; and

(ii)

if requested by Landlord in the exercise of its reasonable business judgment, the proposed
assignee obtaining a guarantee (in form and substance satisfactory to Landlord) from one or more persons
who satisfy Landlord’s standards of creditworthiness; and

(iii)

the proposed assignee is of a character and financial worth such as is in keeping with the

standards of Landlord in those respects for the Property, the assignee’s tenancy is of the same quality as
other tenants at the Property, and the purposes for which the proposed assignee intends to use the Premises
are uses expressly permitted by and not prohibited by this Lease or prohibited by any other lease at the
Property.

14.3

Additional  Rent.  If  Tenant  shall  fail  to  pay  when  due  any  sums  under  this  Lease  designated  as  an
Escalation Charge or other Additional Rent, Landlord shall have the same rights and remedies as Landlord has hereunder for
failure to pay Basic Rent.

14.4

Remedying Defaults. Following the expiration of applicable notice and cure periods, Landlord shall have
the right, but shall not be required, to pay such sums or do any act which requires the expenditure of monies which may be
necessary or appropriate by reason of the failure or neglect of Tenant to perform any of the provisions of this Lease, and in
the event of the exercise of such right by Landlord, Tenant agrees to pay to Landlord forthwith upon demand all such sums,
together with interest thereon at the Default Interest Rate, as Additional Rent.

14.5

Remedies Cumulative. The specified remedies to which Landlord may resort hereunder are not intended to
be exclusive of any remedies or means of redress to which Landlord may at any time be entitled lawfully, and Landlord may
invoke any remedy (including the remedy of specific performance) allowed at law or in equity as if specific remedies were
not

54

herein provided for. Nothing in this Lease shall prohibit Tenant from pursuing such remedies as may be available to Tenant
in equity, including injunctive relief and specific performance. In no event shall Tenant be liable for any indirect or
consequential damages, except as set forth in Section 12.1.

14.6

Enforcement Costs. Tenant shall pay all costs and expenses (including, without limitation, attorneys’ fees

and expenses at both the trial and appellate levels) incurred by or on behalf of Landlord in connection with the successful
enforcement of any rights of Landlord or obligations of Tenant hereunder, whether or not occasioned by an Event of Default.

14.7 Waiver.

(a)

Failure on the part of Landlord or Tenant to complain of any action or non-action on the part of the
other, no matter how long the same may continue, shall never be a waiver by Tenant or Landlord, respectively, of any of the
other’s rights hereunder. Further, no waiver at any time of any of the provisions hereof by Landlord or Tenant shall be
construed as a waiver of any of the other provisions hereof, and a waiver at any time of any of the provisions hereof shall not
be construed as a waiver at any subsequent time of the same provisions. The consent or approval of Landlord or Tenant to or
of any action by the other requiring such consent or approval shall not be construed to waive or render unnecessary
Landlord’s or Tenant’s consent or approval to or of any subsequent similar act by the other.

(b)

Any waiver by either party of any provisions of this Lease must be in a writing signed by the party
against whom such waiver is claimed. In addition, Landlord’s acceptance of any payment from Tenant after a termination of
this Lease due to an Event of Default by Tenant shall not have the effect of reinstating this Lease, nor estop Landlord from
exercising any of the rights and remedies granted to Landlord hereunder arising out of such Event of Default. No payment
by Tenant or acceptance by Landlord of a lesser amount than the Basic Rent, Escalation Charges, Additional Rent and other
sums due hereunder shall be deemed to be other than on account of the total amount due from Tenant to Landlord, to be
applied in such order as Landlord deems appropriate. In no event shall any endorsement or statement on any check or
accompanying any check or payment be deemed an accord and satisfaction; and Landlord may accept such check or
payment without prejudice to Landlord’s right to recover the balance of such Basic Rent, Escalation Charges, Additional
Rent or other sum and to pursue any other remedy provided in this Lease.

14.8

Security Deposit. If a security deposit is specified in Section 1.1 hereof, Tenant agrees that the same will be

paid upon execution and delivery of this Lease, and that Landlord shall hold the same throughout the Term of this Lease as
security for the performance by Tenant of all obligations on the part of Tenant hereunder. Landlord shall have the right from
time to time, without prejudice to any other remedy Landlord may have on account thereof, to apply such deposit (or if the
security deposit is in the form of a Letter of Credit, to draw on the same and so apply such drawn proceeds), or any part
thereof, to Landlord’s damages arising from, or to cure, any Event of Default. If Landlord shall so apply any or all of such
deposit, Tenant shall immediately upon demand deposit with Landlord the amount so applied to be held as security
hereunder. Landlord shall return the deposit, or so much thereof as shall not have theretofore been applied in accordance
with the terms of this Section, to Tenant on the expiration or earlier

55

termination of the Term of this Lease and surrender of possession of the Premises by Tenant to Landlord at such time,
provided that there is then existing no Event of Default (nor any circumstance which, with the passage of time or the giving
of notice, or both, would constitute an Event of Default). While Landlord holds such deposit, Landlord shall have no
obligation to pay interest on the same and shall have the right to commingle the same with Landlord’s other funds. If
Landlord conveys Landlord’s interest under this Lease, the deposit, if the same is in the form of cash, or any part thereof not
previously applied, shall be turned over or credited by Landlord to Landlord’s grantee, and, thereafter, Tenant agrees to look
solely to such grantee for proper application of the deposit in accordance with the terms of this Section, and the return
thereof in accordance herewith. The holder of a mortgage shall not be responsible to Tenant for the return or application of
any such deposit, whether or not it succeeds to the position of Landlord hereunder, unless such deposit shall have been
received in hand by such holder.

If the security deposit is in the form of a Letter of Credit, the Letter of Credit shall have a stated duration of and shall be
effective for at least one (1) year with provision for automatic successive annual one-year extensions during the Term and for
sixty (60) days thereafter. Tenant shall keep the Letter of Credit in force throughout the Term and for sixty (60) days after the
expiration date or the earlier termination of the Term, except that if such earlier termination is based on a default by Tenant
hereunder, Tenant shall keep the Letter of Credit in force until sixty (60) days after the date when the Term would have
expired had it not been earlier terminated. Tenant shall deliver to Landlord a renewal Letter of Credit no later than thirty (30)
days prior to the expiration date of any Letter of Credit issued under this Section 14.8, and if Tenant fails to do so, Landlord
may draw the entire amount of the expiring Letter of Credit and hold the proceeds in cash as the security deposit, as
hereinafter provided, but in that event, Tenant shall, upon demand, provide Landlord with a new Letter of Credit, meeting
the requirements of this Lease as the security deposit, in lieu of such cash, and upon receipt of such replacement Letter of
Credit, Landlord shall promptly return such cash security deposit to Tenant. The Letter of Credit shall be issued by a
commercial bank satisfactory to and reasonably approved by Landlord and shall be in a form reasonably approved by
Landlord, the parties acknowledging that Bank of America, N.A. is an approved issuer.

If Landlord so uses or applies all or any portion of the Letter of Credit, Tenant shall within twenty (20) days after written
demand therefor, restore the Letter of Credit to the initial face amount thereof. If Tenant performs all of Tenant's obligations
hereunder, the Letter of Credit, or so much thereof as shall not then have been applied by Landlord, shall be returned without
payment of interest or other amount for its use, to Tenant (or, at Landlord's option, to the last assignee, if any, of Tenant's
interest hereunder) within a reasonable time (not to exceed sixty (60) days) after the expiration of the Term hereof, and after
Tenant has vacated and delivered the Premises as required hereunder. No trust relationship is created herein between
Landlord and Tenant with respect to the Letter of Credit. Tenant acknowledges that the Letter of Credit is not an advance
payment of any kind or a measure of or limit on Landlord's damages in the event of Tenant's default. Any application of the
Letter of Credit by Landlord shall be without prejudice to any other right or remedy. If Landlord conveys Landlord's interest
under this Lease, the Letter of Credit, or any part thereof not previously applied, shall be turned over by Landlord to
Landlord's grantee, and, once turned over, Tenant agrees to look solely to such grantee for proper application of the Letter of
Credit in accordance with the terms of this Section 14.8, and the return thereof in accordance herewith (and if required,
Tenant shall cooperate as necessary to

56

transfer the Letter of Credit to such grantee). The holder of a mortgage shall not be responsible to Tenant for the return or
application of any the Letter of Credit, whether or not it succeeds to the position of Landlord hereunder, unless the Letter of
Credit shall have been received in hand by such holder. Tenant hereby waives the provisions of any law which is inconsistent
with this Section 14.8.

14.9

Landlord’s Default. Landlord shall in no event be in default under this Lease unless Landlord shall neglect

or fail to perform any of its obligations hereunder and shall fail to remedy the same within thirty (30) days after notice to
Landlord specifying such neglect or failure, or if such failure is of such a nature that Landlord cannot reasonably remedy the
same within such thirty (30) day period, Landlord shall fail to commence promptly (and in any event within such thirty (30)
day period) to remedy the same and to prosecute such remedy to completion with diligence and continuity.

14.10

Independent Covenants. Tenant hereby acknowledges and agrees that (i) the obligations of Tenant

hereunder shall be separate and independent covenants and agreements, (ii) the obligations of Tenant hereunder, including,
without limitation the obligation to pay Basic Rent, Escalation Charges, Additional Rent and other sums due hereunder, shall
continue unaffected, unless the requirement to pay or perform the same shall have been terminated or abated pursuant to an
express provision of this Lease, and (iii) Tenant shall have no right to withhold or abate any payment of Basic Rent,
Escalation Charges, Additional Rent or any other sums due hereunder, or to set off any amount against any such payment of
Basic Rent, Escalation Charges, Additional Rent or any other sums due hereunder or to terminate this Lease, because of any
default or alleged default by Landlord under this Lease or because of the condition of the Premises, except to the extent
expressly set forth in this Lease. Such waiver and acknowledgements by Tenant are a material inducement to Landlord
entering into this Lease. To the extent of any conflicts or inconsistencies between the terms and provisions of this Section
14.10 and the terms and provisions of the remainder of this Lease, the terms and provisions of this Section 14.10 shall
control.

ARTICLE 15
MISCELLANEOUS PROVISIONS

15.1

Landlord’s Rights of Access. Landlord and its agents, representatives, contractors and employees shall
have the right to enter the Premises upon prior reasonable notice (except in an emergency, in which event Landlord shall
endeavor to give such notice as is reasonably practicable under the circumstances and in all events notice under this Article
15 may be by telephone notwithstanding anything to the contrary in this Lease) for the purpose of doing maintenance,
making such repairs, alterations or improvements as Landlord shall reasonably require or shall have the right to make by the
provisions of this Lease or otherwise in exercising Landlord’s rights or fulfilling Landlord’s obligations under this Lease.
Landlord and its agents, representatives, contractors and employees shall have the right to enter the Premises without notice
to Tenant for the purpose of performing janitorial and other services which Landlord is obligated to provide under this Lease
or for exercising any of Landlord’s rights under Article 14 of this Lease. Landlord and its invitees shall also have the right
on reasonable prior notice to enter the Premises, for the purpose of inspecting them or exhibiting them to prospective

57

purchasers, prospective or actual Superior Lessors or Superior Mortgagees of the Building and, during the final twelve (12)
months of the Term, to prospective tenants. For each of the above purposes, Landlord shall at all times have a key with
which to unlock all the doors in the Premises, excluding Tenant’s vaults, safes and special security areas designated in
advance by Tenant to Landlord. In an emergency, Landlord shall have the right to use any means that Landlord may deem
proper to open the doors in and to the Premises. Any entry into the Premises by Landlord in the manner hereinbefore
described shall not be deemed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an actual or
constructive eviction of Tenant from any portion of the Premises. No provision of this Lease shall be construed as obligating
Landlord to perform any repairs, alterations or decorations except as otherwise expressly agreed to be performed by
Landlord in this Lease.

Except in emergency situations, anyone who has access to any portion of the Premises pursuant to this Lease
after Tenant has first commenced to use the Premises for the Permitted Uses may, at Tenant’s election, be subject to Tenant’s
reasonable security measures and protocols, requiring the wearing of an ID badge, and obligating visitors to comply with
reasonable protocols so as protect confidential information contained within the Premises. Except in the event of an
emergency, and except as otherwise approved by Tenant, any entry in the Premises must be done in the presence of a
representative of Tenant so long as Tenant makes such representative available in a reasonable manner (and in any event
within twenty-four hours of Landlord’s notice provided under the preceding paragraph). Tenant may prohibit access to
certain areas of the Premises (“Secure Areas”) reasonably identified by Tenant in a prior written notice to Landlord from
time to time, which notice shall set forth the reasonable basis on which Tenant has determined that access must be prohibited
to such areas in non-emergency situations (provided that in the event that Landlord requires access to such Secure Areas to
maintain, repair or replace the Building and/or any Common Facilities, Landlord may access such Secure Areas on
reasonable prior notice to Tenant to perform such maintenance, repair or replacement, subject to Tenant’s reasonable safety
protocols). In no event shall Landlord be deemed to be in default hereunder, nor shall Landlord have any liability hereunder,
to the extent that Landlord is prevented from performing any of its obligations as a result of its inability to access the Secure
Areas in non-emergency situations. Notwithstanding the foregoing, in case of emergency, Landlord may enter any part of the
Premises (including without limitation the Secure Areas) without prior notice or a Tenant’s representative; provided that
Landlord provides Tenant with notice of such entry as soon as reasonably possible thereafter and Landlord takes reasonable
precautions to protect the health and safety of its entrants.

15.2

Covenant of Quiet Enjoyment. Subject to the terms and conditions of this Lease, on payment of the Basic

Rent and Escalation Charges and other Additional Rent and observing, keeping and performing all of the other terms and
conditions of this Lease on Tenant’s part to be observed, kept and performed (subject in all events to applicable notice and
cure periods), Tenant shall lawfully, peaceably and quietly enjoy the Premises during the term hereof, without interference,
hindrance or ejection by any persons lawfully claiming under Landlord to have title or other rights to the Premises superior
to Tenant. The foregoing covenant of quiet enjoyment is in lieu of any other covenant, express or implied.

58

15.3

Landlord’s Liability.

(a)

Tenant agrees to look solely to  Landlord’s then equity interest in the Property at the time of 

recovery for recovery of any judgment against Landlord, and agrees that neither Landlord nor any successor of Landlord nor 
any beneficiary, trustee, member, manager, partner, director, officer, employee or shareholder of Landlord or such successor 
shall ever be personally liable for any such judgment, or for the payment of any monetary obligation to Tenant. The 
provision contained in the foregoing sentence is not intended to, and shall not, limit any right that Tenant might otherwise 
have to obtain injunctive relief against Landlord or any successor of Landlord, or to take any action not involving the 
personal liability of Landlord or any successor of Landlord to respond in monetary damages from Landlord’s assets other 
than Landlord’s equity interest in the Property. Nothing in this Section 15.3(a) shall prevent Tenant from naming Landlord as 
a defendant in any lawsuit where necessary to pursue damages or equitable relief in a manner otherwise permitted pursuant 
to this Lease. In the event of a sale or conveyance by Landlord of the Building or the Property, Landlord shall be released 
from any and all liability under this Lease accruing after the date of such transfer and so long as the same are assumed by the 
successor in interest expressly or by operation of law.

(b)

In no event shall Landlord ever be liable to Tenant for any loss of business or any other indirect,

special or consequential damages suffered by Tenant from whatever cause, nor for any punitive damages, and Tenant waives
any rights it may have to such damages under this Lease in the event of a breach or default by Landlord under this Lease.

(c)

Where provision is made in this Lease for Landlord’s consent, and Tenant shall request such

consent, and Landlord shall fail or refuse to give such consent, Tenant shall not be entitled to any damages for any
withholding by Landlord of its consent, it being intended that Tenant’s sole remedy shall be an action for specific
performance or injunction, and that such remedy shall be available only in those cases where Landlord has expressly agreed
in writing not to unreasonably withhold its consent. Furthermore, whenever Tenant requests Landlord’s consent or approval
(whether or not provided for herein), Tenant shall pay to Landlord, on demand, as Additional Rent, any reasonable expenses
incurred by Landlord (including without limitation reasonable attorneys’ fees and costs, if any) in connection therewith.

(d)

Any repairs or restoration required or permitted to be made by Landlord under this Lease may be

made during normal business hours, and Landlord shall have no liability for damages to Tenant for inconvenience,
annoyance or interruption of business arising therefrom.

15.4

Estoppel Certificate. Tenant shall, at any time and from time to time, upon not less than ten (10) Business
Days prior written notice by Landlord, execute, acknowledge and deliver to Landlord an estoppel certificate containing such
statements of fact as Landlord reasonably requests.

15.5

Brokerage. Tenant warrants and represents that Tenant has dealt with no broker in connection with the
consummation of this Lease other than Broker(s), and, in the event of any brokerage claims against Landlord predicated
upon dealings with Tenant, Tenant agrees to defend the same and indemnify Landlord against any such claim, except any
claim by the

59

Broker(s), and all costs, expenses and liabilities incurred in connection with such claims, including reasonable attorneys’
fees and costs. Landlord shall pay any commission or fees due to the Broker(s) in connection with this Lease pursuant to a
separate written instrument between Landlord and Broker(s). Landlord warrants and represents that Landlord has dealt with
no broker in connection with the consummation of this Lease other than Broker(s), and, in the event of any brokerage claims
against Tenant predicated upon dealings with Landlord, Landlord agrees to defend the same and indemnify Tenant against
any such claim, and all costs, expenses and liabilities incurred in connection with such claims, including reasonable
attorneys’ fees and costs.

15.6

Rules and Regulations. Tenant, its employees, representatives, agents, subtenants, licensees, contractors,

and invitees shall abide by the Rules and Regulations from time to time established by Landlord, it being agreed that
Landlord shall have the right from time to time during the Term to make reasonable changes in and additions to the Rules
and Regulations as Landlord deems necessary for the management, safety, care, cleanliness, conservation and sustainability
of the Building and the Property and for the preservation of good order therein, provided that no such changes shall apply to
Tenant until Tenant has written notice of the same or shall materially increase Tenant’s obligations hereunder. The Rules and
Regulations shall be generally applicable to all tenants of the Building of similar nature to the Tenant named herein.
Landlord agrees that any such Rules and Regulations will be uniformly enforced, provided, however, Landlord may waive
any one or more of the Rules and Regulations for the benefit of any particular tenant if Landlord reasonably deems such
waiver appropriate, but no such waiver shall be construed as a waiver of such Rules and Regulations in favor of any other
tenant, nor prevent Landlord from enforcing such Rules and Regulations against any or all tenants of the Building. Landlord
shall not have any obligation to enforce the Rules and Regulations or the terms of any other lease against any other tenant
and Landlord shall not be liable to Tenant for violation thereof by any other tenant, its employees, representatives, agents,
contractors, visitors, subtenants, licensees or invitees. In the event that there shall be a conflict between such Rules and
Regulations and the provisions of this Lease, the provisions of this Lease shall control. The Rules and Regulations currently
in effect are set forth in Exhibit F attached hereto and made a part hereof.

15.7

Financial Statements. So long as Tenant remains an entity whose stock is publicly traded on a national

exchange (or publicly listed in an equivalent manner, such as on NASDAQ) that requires its financial statements to be
publicly disclosed (a “Publicly Traded Tenant”), Tenant shall have no obligation to deliver any financial statements to
Landlord and the remainder of this Section 15.7 shall not be applicable to Tenant. At any time that Tenant is not a Publicly
Traded Tenant, Tenant shall deliver to Landlord, within ten (10) days after Landlord’s reasonable request for the same,
Tenant’s most recently completed financial statements (audited if available) prepared and certified by an independent
certified public accountant and, if not so certified, certified by an officer of Tenant as being true and correct in all material
respects. Landlord and its affiliates and investors shall keep such financial statements confidential, provided that Landlord
shall be permitted to deliver such financial statements to a lender, purchaser or lessor or a prospective lender, purchaser or
lessor in connection with (i) a sale or financing of the Building or the Property or any interest in any deed of trust
encumbering the Building or the Property, or (ii) a sale of all or substantially all of the interests in Landlord or (iii) any other
recapitalization of the equity interests in Landlord, so long

60

as Landlord first advises the recipient of the confidential nature of such statements, or to the extent required by Law. Any
such financial statements may be relied upon by any actual or potential lessor, purchaser, or mortgagee of the Property.

15.8

Confidentiality. Tenant agrees that this Lease and the terms contained herein will be treated as strictly

confidential and except as required by Law (or except with the written consent of Landlord) Tenant shall not disclose the
same to any third party except for Tenant and Tenant’s Transferee’s respective partners, existing and prospective lenders,
existing and prospective investors, accountants, officers, directors, employees, consultants and attorneys who have been
advised of the confidentiality provisions contained herein. In the event Tenant is required by Law to provide this Lease or
disclose any of its terms, Tenant shall, to the extent practicable, give Landlord prompt notice of such requirement prior to
making disclosure so that Landlord may seek an appropriate protective order. If failing the entry of a protective order Tenant
is compelled to make disclosure, Tenant shall only disclose portions of the Lease which Tenant is required to disclose and
will exercise reasonable efforts to obtain assurance that confidential treatment will be accorded to the information so
disclosed.

15.9

Invalidity of Particular Provisions; Saving Clause. If any term or provision of this Lease, or the

application thereof to any person or circumstance shall, to any extent, be invalid or unenforceable, the remainder of this
Lease, or the application of such term or provision to persons or circumstances other than those as to which it is held invalid
or unenforceable, shall not be affected thereby, and each term and provision of this Lease shall be valid and be enforced to
the fullest extent permitted by law. If (but solely to the extent) the limitations on Landlord’s liability set forth in this Lease
would be held to be unenforceable or void in the absence of a modification holding the Landlord liable to Tenant or to
another person for injury, loss, damage or liability arising from Landlord’s omission, fault, negligence or other misconduct
on or about the Premises, or other areas of the Property appurtenant thereto or used in connection therewith and not under
Tenant’s exclusive control, then such provision shall be deemed modified as and to the extent (but solely to the extent)
necessary to render such provision enforceable under applicable Law. The foregoing shall not affect the application of
Section 15.3 to limit the assets available for execution of any claim against Landlord.

15.10 Provisions Binding, Etc. Except as herein otherwise provided, the terms hereof shall be binding upon and
shall inure to the benefit of the successors and assigns, respectively, of Landlord and Tenant (except in the case of Tenant,
only such successors and assigns as may be permitted hereunder) and, if Tenant shall be an individual, upon and to his heirs,
executors, administrators, successors and permitted assigns. Any reference in this Lease to successors and assigns of Tenant
shall not be construed to constitute a consent to assignment by Tenant.

15.11 Recording. Tenant agrees not to record this Lease, but, if the Term of this Lease (including any extended

term) is seven (7) years or longer, each party hereto agrees, on the request of the other, to execute a notice of lease/short
form memorandum of lease in recordable form and complying with applicable Law and shall contain no information other
than what is statutorily required to record a notice of lease/short form memorandum of lease. In no event shall such
document set forth the rent or other charges payable by Tenant under this Lease; and any such document shall expressly state
that it is executed pursuant to the provisions contained in this Lease, and is not intended to vary the terms and conditions of
this Lease. At any time

61

following Landlord’s request following the expiration of the Term or earlier termination of this Lease, Tenant shall execute
and deliver to Landlord within ten (10) days after such request a release of any document recorded in the real property
records for the location of the Property evidencing this Lease or notice of termination of this Lease in recordable form. The
obligations of Tenant under this Section shall survive the expiration or any earlier termination of the Term.

15.12 Notice. Whenever, by the terms of this Lease, notice shall or may be given either to Landlord or to Tenant

(excluding notices pursuant to Section 15.1), such notice shall be in writing and shall be sent by hand, registered or certified
mail, or overnight, e-mail of a notice sent as a PDF attachment or other commercial courier, postage or delivery charges, as
the case may be, prepaid as follows:

If intended for Landlord, addressed to Landlord at the address set forth in Article 1 of this Lease (or to such

other address or addresses as may from time to time hereafter be designated by Landlord by like notice).

If intended for Tenant, addressed to Tenant at the address set forth in Article 1 of this Lease except that from
and after the Commencement Date the address of Tenant shall be the Premises (or to such other address or addresses
as may from time to time hereafter be designated by Tenant by like notice).

Except as otherwise provided herein, all such notices shall be effective when received; provided, that (i) if receipt is
refused, notice shall be effective upon the first occasion that such receipt is refused, (ii) if the notice is unable to be delivered
due to a change of address of which no notice was given, notice shall be effective upon the date such delivery was attempted,
or (iii) if the notice is sent by e-mail, such notice shall be effective when received (or, if after 5 p.m. on a business day, the
next business day following receipt).

Any notice given by an attorney on behalf of Landlord or by Landlord’s managing agent shall be considered as

given by Landlord and shall be fully effective.

15.13 Authority. Each of Landlord and Tenant hereby represents and warrants to the other party that (i) it is duly
organized and validly existing in good standing under the laws of the state of its organization or incorporation as set forth in
Section 1.1, and possesses all licenses and authorizations necessary to carry on its business, (ii) it has full power and
authority to carry on its business, enter into this Lease and consummate the transaction contemplated by this Lease, (iii) the
individual executing and delivering this Lease on its behalf has been duly authorized to do so, (iv) this Lease has been duly
executed and delivered by it, (v) this Lease constitutes its valid, legal, binding and enforceable obligation (subject to
bankruptcy, insolvency or creditor rights laws generally, and principles of equity generally), (vi) the execution, delivery and
performance of this Lease by it will not cause or constitute a default under, or conflict with, its organizational documents or
any agreement to which it is a party, (vii) the execution, delivery and performance of this Lease by it will not violate any
applicable Law, and (viii) all consents, approvals, authorizations, orders or filings of or with any court or governmental
agency or body, if any, required on its part for the execution, delivery and performance of this Lease have been obtained or
made.

62

15.14 When Lease Becomes Binding; Entire Agreement; Modification. The submission of this document for

examination and negotiation does not constitute an offer to lease, or a reservation of, or option for, the Premises, and this
document shall become effective and binding only upon the execution and delivery hereof by both Landlord and Tenant.
This Lease is the entire agreement between Landlord and Tenant, and this Lease expressly supersedes any negotiations,
considerations, representations and understandings and proposals or other written documents relating hereto. This Lease may
be modified or altered only by written agreement between Landlord and Tenant, and no act or omission of any employee or
agent of Landlord shall alter, change or modify any of the provisions hereof.

15.15 Paragraph Headings and Interpretation of Sections. The paragraph headings throughout this instrument
are for convenience and reference only, and the words contained therein shall in no way be held to explain, modify, amplify
or aid in the interpretation, construction or meaning of the provisions of this Lease. The provisions of this Lease shall be
construed as a whole, according to their common meaning (except where a precise legal interpretation is clearly evidenced),
and not for or against either party. Use in this Lease of the words “including,” “such as” or words of similar import, when
followed by any general term, statement or matter, shall not be construed to limit such term, statement or matter to the
specified item(s), whether or not language of non-limitation, such as “without limitation” or “including, but not limited to,”
or words of similar import, are used with reference thereto, but rather shall be deemed to refer to all other terms or matters
that could fall within a reasonably broad scope of such term, statement or matter.

15.16

Joint and Several Liability; Successors and Assigns. If there shall be more than person or entity which

constitute the “Tenant” hereunder, the obligations of Tenant hereunder shall be joint and several for all such persons and
entities. The covenants and conditions herein contained, subject to the provisions as to assignment, shall inure to and bind
the heirs, successors, executors, administrators and assigns of the parties hereto.

15.17 Waiver of Jury Trial. In any action or proceeding arising herefrom, Landlord and Tenant hereby consent to
(i) the jurisdiction of any competent court within the state where the Building is located, (ii) service of process by any means
authorized by the law of the state where the Building is located, and (iii) in the interest of saving time and expense, trial
without a jury in any action, proceeding or counterclaim brought by either of the parties hereto against the other or their
successors in respect of any matter arising out of or in connection with this Lease, the relationship of Landlord and Tenant,
Tenant’s use or occupancy of the premises, and/or any claim for injury or damage, or any emergency or statutory remedy. In
the event Landlord commences any summary proceedings or action for nonpayment of Basic Rent or Additional Rent,
Tenant shall not interpose any counterclaim of any nature or description (unless such counterclaim shall be mandatory) in
any such proceeding or action, but shall be relegated to an independent action at law.

15.18 Reservation. Nothing set forth in this Lease shall be deemed or construed to restrict Landlord from making

any repairs, renovations, replacements, improvements and modifications to, or to reconfigure, any of the parking or
Common Facilities serving the Property, and Landlord expressly reserves the right to make any such repairs, renovations,
replacements, improvements and modifications or reconfigurations to such areas and other

63

facilities of the Building and Common Facilities as Landlord may deem appropriate, including the addition or deletion of
temporary or permanent improvements therein, or the conversion of areas now dedicated for the non- exclusive common use
of tenants (including Tenant) to the exclusive use of one or more tenants or licensees within the Building, provided that none
of the foregoing unreasonably interfere with Tenant’s use of the Premises or materially increase Tenant’s obligations
hereunder. In connection with the foregoing, Landlord may temporarily close or cover entrances, doors, windows, corridors,
or other facilities without liability to Tenant; however, in doing so, Landlord shall use commercially reasonable efforts to not
unreasonably interfere with or disturb Tenant’s use and occupancy of the Premises.

15.19 Prohibited Persons and Transactions. Tenant represents and warrants that neither Tenant nor any of its
affiliates, nor any of their respective partners, members, shareholders or other equity owners (provided, that to the extent
Tenant or any of such affiliates or their respective partners, members, shareholders, or other equity owners is an entity whose
stock is publicly traded on a national exchange (or publicly listed in an equivalent manner, such as on NASDAQ) then this
representation and warranty with respect to such shareholders who have acquired shares on such national exchange shall be
limited to Tenant’s knowledge), and none of their respective employees, officers, directors, representatives or agents is, nor
will they become, a person or entity with whom U.S. persons or entities are restricted from doing business under regulations
of the Office of Foreign Asset Control (“OFAC“) of the Department of the Treasury (including those named on OFAC’s
Specially Designated and Blocked Persons List) or under any statute, executive order (including the September 24, 2001,
Executive Order Blocking Property and Prohibiting Transactions with Persons Who Commit, Threaten to Commit, or
Support Terrorism), or other governmental action and is not and will not Transfer this Lease to, contract with or otherwise
engage in any dealings or transactions or be otherwise associated with such persons or entities.

15.20 Time Is of the Essence.  Time is of the essence of each provision of this Lease.

15.21 Matters of Record. Except as otherwise provided herein, this Lease and Tenant’s rights hereunder are

subject and subordinate to all matters affecting Landlord’s title to the Property recorded in the real property records of the
County in which the Property is located, prior to and subsequent to (to the extent not adversely affecting Tenant’s rights, or
increasing Tenant’s obligations, hereunder) the date hereof, including, without limitation, all covenants, conditions and
restrictions. Tenant agrees for itself and all persons in possession or holding under it that it will comply with and not violate
any such covenants, conditions and restrictions or other matters of record affecting Landlord’s title to the Property, if any.
Landlord reserves the right, from time to time, to grant such easements, rights and dedications as Landlord deems necessary
or desirable, and to cause the recordation of parcel maps and covenants, conditions and restrictions affecting the Premises,
the Building or the Property, as long as such easements, rights, dedications, maps, and covenants, conditions and restrictions
do not materially and adversely interfere with the use of the Premises by Tenant. At Landlord’s request, Tenant shall join in
the execution of any of the aforementioned documents (but without cost or liability to Tenant).

15.22 Air and Light/Roof/Exterior. This Lease does not grant or guarantee Tenant continuance of or any right of

a view or an easement for light or air over any property adjoining

64

the Premises or the Building. Except as set forth in Section 2.2(f), Tenant shall have no right of access to the roof of the
Premises or the Building and shall not install, repair or replace any aerial, fan, air conditioner or other device on the roof of
the Premises or the Building without the prior written consent of the Landlord. Landlord shall have the right at any time to
install, affix and maintain any and all signs on the exterior and on the interior of the Building as Landlord may, in Landlord’s
sole discretion, desire, and to prescribe the location and style of all signs visible from the Common Areas or from the
exterior of the Building

15.23 ERISA. Tenant is not an “employee benefit plan” as defined in Section 3(3) of the Employee Retirement

Income Security Act of 1974 (“ERISA”), which is subject to Title I of ERISA, or a “plan” as defined in Section 4975(e)(1)
of the Internal Revenue Code of 1986, which is subject to Section 4975 of the Internal Revenue Code of 1986; and (b) the
assets of Tenant do not constitute “plan assets” of one or more such plans for purposes of Title I of ERISA or Section 4975
of the Internal Revenue Code of 1986; and (c) Tenant is not a “governmental plan” within the meaning of Section 3(32) of
ERISA, and assets of Tenant do not constitute plan assets of one or more such plans; or (d) transactions by or with Tenant
are not in violation of state statutes applicable to Tenant regulating investments of and fiduciary obligations with respect to
governmental plans.

15.24 Multiple Counterparts; Entire Agreement. This Lease may be executed in multiple counterparts, and in

electronic format, such as PDF or DocuSign, each of which shall be deemed an original and all of which together shall
constitute one and the same document. This Lease constitutes the entire agreement between the parties hereto, Landlord’s
managing agent and their respective affiliates with respect to the subject matter hereof and thereof and supersedes all prior
dealings between them with respect to such subject matter, and there are no verbal or collateral understandings, agreements,
representations or warranties not expressly set forth in this Lease. No subsequent alteration, amendment, change or addition
to this Lease shall be binding upon Landlord or Tenant, unless reduced to writing and signed by the party or parties to be
charged therewith.

15.25 Governing Law.  This  Lease  shall  be  governed  by  the  laws  of  the  state  in  which  the  Property  is  located,

without regard to application of any conflict of law principles.

EXHIBIT C
Work Letter

1.        Preparation of Plans. Landlord has prepared, and Tenant hereby approves, the plans and specifications listed
on Schedule C-1 attached hereto for the interior finish and other tenant improvements to the Premises (as the same exist on
the date of this Lease in the form attached hereto as Schedule C-1, the “Baseline Plans;” the Baseline Plans as the same may
be modified, from time to time, by Changes in accordance with this Work Letter, the “Approved Plans”). The parties intend
that (x) Landlord shall be responsible at its sole cost and expense for the hard and soft costs of completing the work to the
Premises shown in the Baseline Plans, which work Landlord has commenced prior to the date of this Lease, and (y) Tenant
shall be responsible at its sole cost and expense for the hard and soft costs necessary to effect any Changes (as defined
below).

2.         Performance of Landlord’s Work. Promptly after the mutual execution of this Lease, using Building standard
materials, finishes, equipment and installations (except where indicated on the Baseline Plans (if applicable) (such standard,
the “Building Standard”), Landlord shall commence and exercise all reasonable efforts to complete the improvements to
the Premises as shown on the Approved Plans (collectively, “Landlord’s Work”) at Landlord’s sole cost and expense except
as expressly provided herein (including without limitation, with respect to any Changes, which will be at Tenant’s sole cost
and expense); provided, however, that Tenant shall be responsible for all work identified in the “Tenant Install” column in
the Responsibility Matrix attached hereto as Schedule C-2 to the extent that Tenant desires the same. In the event that
Tenant requests that the Landlord’s Work be performed in variation of the Baseline Plans (and/or in variation of any
Approved Plans) or that Landlord use materials, finishes, equipment or installations that vary from the Baseline Plans
(and/or in variation of any Approved Plans), and Landlord agrees to so modify Landlord’s Work in accordance with this
Work Letter (such agreement not to be unreasonably withheld, conditioned, or delayed) (any such request approved by
Landlord, a “Change”), Tenant will be responsible for any increase to the actual, out of pocket hard and soft costs for
Landlord to evaluate any requested Change (whether or not the same is approved by Landlord) and for Landlord to complete
the Landlord’s Work on account of such Change (including without limitation, any work necessary to undo or reverse any
previously-completed Landlord’s Work to make the Premises ready for the Change to be performed), which Tenant shall pay
to Landlord within fifteen (15) days after receipt of an invoice therefor as such work progresses and Landlord provides
Tenant with reasonable evidence of the same. Prior to proceeding with any requested Change, Landlord shall provide Tenant
with an order of magnitude estimate of any such additional costs and an estimate of the additional time needed for Landlord
to Substantially Complete the Landlord’s Work on account of effecting such Change (including without limitation, additional
design, engineering and construction time and an estimate of any delays described in subsections (b) and (c) of the definition
of Tenant Delays set forth in Section 5 below) (the “Cost/Time Estimate”), which additional time shall constitute a Tenant
Delay, subject to the provisions below. Tenant shall have two (2) business days to provide Landlord with written notice that
Tenant has elected to proceed with the Change,

C-1

in which case, the Tenant shall be responsible for the additional costs set forth in the Cost/Time Estimate and such additional
time to achieve Substantial Completion set forth in the Cost/Time Estimate shall be deemed to constitute a Tenant Delay;
and if Tenant fails to respond within such two (2) business day period, Tenant shall be deemed to have elected to not proceed
with the Change. Within 90 days following the final completion of the Landlord’s Work, Landlord shall provide Tenant with
a final accounting of the Landlord’s Work payable by Tenant, together with all applicable back up from the contractor and
subcontractors, showing the actual cost of Landlord’s Work payable by Tenant and the amounts previously contributed by
Tenant, such that Tenant shall pay the proper amount due hereunder. Landlord shall reimburse Tenant for any overpayment,
and Tenant shall reimburse Landlord for any underpayment, of the cost of Landlord’s Work payable by Tenant within 30
days following such final reconciliation.

The Baseline Plans and Approved Plans may not be modified other than in accordance with an approved Change,
and Landlord shall construct the Landlord’s Work in accordance with the Approved Plans (as modified by such Changes).
Landlord and Tenant shall hold weekly design meetings and construction meetings during the progress of the Landlord’s
Work, and Tenant shall be entitled to have a representative present at each of Landlord’s regularly scheduled weekly
construction meetings with the contractor. With respect to any Change, Landlord, in good faith, shall provide Tenant with
“open book” full access to all aspects of the pricing and construction of the work covered by such Change.

If the Substantial Completion Date (subject to acceleration as set forth below on account of Tenant Delay) does not

occur by the date that is 30 days following the Estimated Commencement Date, subject to extension for Force Majeure, then
Tenant shall be entitled to a day for day abatement of Base Rent for each day until the Substantial Completion Date. If the
Substantial Completion Date (subject to acceleration as set forth below on account of Tenant Delay) does not occur by the
date that is 180 days following the Estimated Commencement Date, subject to extension for Force Majeure, then Tenant may
elect to terminate this Lease upon 30 days prior written notice to Landlord (provided that if Substantial Completion occurs
within such 30 day period, then such termination notice shall be null and void).

3.

Substantial Completion. The Landlord’s Work shall be deemed substantially complete on the first day as of

which Landlord’s Work has been completed except for customary, minor items of work (and, if applicable, adjustment of
equipment and fixtures) which can be completed after occupancy has been taken without unreasonably interfering with
Tenant’s operation of its business in the Premises (i.e. so-called “punch list” items) (“Substantially Complete”); provided,
however, that if substantial completion of Landlord’s Work is delayed as a result of any Tenant Delays described in Section 5
below, then Substantial Completion shall be the date that Landlord’s Work would have been substantially completed but for
such Tenant Delays (nothing in this sentence, however, being deemed to relieve Landlord of its obligation to complete the
Landlord’s Work). Landlord and Tenant shall inspect the Premises within five days following the occurrence of Substantial
Completion and Landlord’s architect shall prepare the punchlist for review and comment by Landlord and Tenant based on
such inspection. The date upon which Substantial Completion occurs is hereinafter called the “Substantial Completion
Date.” Subject to Tenant Delays and Force Majeure, Landlord will exercise commercially

C-2

reasonable efforts to complete the “punch list” items as soon as conditions reasonably permit, and in any event within 60
days following the Substantial Completion Date, and Tenant shall afford Landlord reasonable access to the Premises for such
purposes. Except to the extent the same is accelerated on account of a Tenant Delay, the Substantial Completion Date shall
not be deemed to have occurred unless and until Landlord has obtained the necessary municipal sign-offs permitting Tenant
to lawfully occupy the Premises (except to the extent that the same are unavailable due to (x) any uncompleted work
identified in the “Tenant Install” column in the Responsibility Matrix attached hereto as Schedule C-2, or (y) any Tenant
fixturization required to be completed as a condition of the issuance of the same), the Premises are broom clean, Landlord’s
architect has certified that Substantial Completion has occurred, the Premises are in compliance with all applicable Laws,
free from Hazardous Materials (except those introduced by any Tenant Party) and the Premises are free of occupants and any
personal property of Landlord or any third party (except to the extent contemplated by the Approved Plans), with all
Building systems serving the Premises in good working order and condition.

4.

 Condition; Landlord’s Performance. Tenant shall give Landlord notice, not later than 350 days after the

Commencement Date, of any respects in which Landlord has not performed Landlord’s Work fully, properly and in
accordance with the terms of this Lease. Except as identified in any such notice from Tenant to Landlord, Tenant shall have
no right to make any claim that Landlord has failed to perform any of Landlord’s Work fully, properly and in accordance
with the terms of this Lease or to require Landlord to perform any further Landlord’s Work. Landlord shall obtain a one-year
construction warranty from the contractor for the Landlord’s Work. In addition, after expiration of such one (1) year period,
Landlord shall use commercially reasonable efforts (at Tenant’s written request and Tenant’s cost and expense) to enforce
any rights under Landlord’s construction contract for the Landlord’s Work with respect to any defects first discovered after
expiration of such one (1) year period; provided further that Tenant shall reimburse Landlord for such costs within thirty (30)
days of Landlord invoicing Tenant therefor.

If and as long as Tenant does not interfere in any way with the construction process (by causing disharmony of labor
relations at the Property, scheduling or coordination difficulties, etc.), Tenant may, at Tenant’s sole risk and expense, enter
the Premises within the sixty (60) day period prior to the Commencement Date for the purpose of installing Tenant’s
furniture, fixtures, equipment and telecommunications wiring and cabling (collectively, the “FF&E”). The provisions of this
paragraph shall apply only during the period prior to the Commencement Date. Prior to the Commencement Date, Tenant
shall comply with and perform, and shall cause its employees, agents, contractors, subcontractors, material suppliers and
laborers to comply with and perform, all of Tenant’s obligations under this Lease except the obligations to pay Base Rent,
Additional Rent and additional charges and other charges and other obligations the performance of which would be clearly
incompatible with the installation of the FF&E. Any independent contractor of Tenant (or any employee or agent of Tenant)
performing any work in the Premises prior to the Commencement Date shall be subject to all of the terms, conditions and
requirements contained herein. Neither Tenant nor any Tenant contractor shall interfere in any way with construction of, nor
damage, the Landlord’s Work or the common areas or other parts of the Building, and each shall do all things reasonably
requested by Landlord to expedite

C-3

construction of the Landlord’s Work. Without limitation, Tenant shall require each Tenant contractor to adjust and coordinate
any work or installation in or to the Premises to meet the schedule or requirements of other work being performed by or for
Landlord throughout the Building. In all events, Tenant shall indemnify Landlord in the manner provided in the Lease
against any claim, loss or cost arising out of any interference with, or damage to, the Landlord’s Work or any other work in
the Building, or any delay thereto, or any increase in the cost thereof on account in whole or in part of any act, omission,
neglect or default by Tenant or any Tenant contractor. Without limiting the generality of the foregoing, to the extent that the
commencement or performance of Landlord’s Work is actually delayed in whole or in part on account of any act, omission,
neglect, or default by Tenant or any Tenant contractor, then such delay shall constitute a Tenant Delay. Any requirements of
any such Tenant contractor for services from Landlord or Landlord’s contractor, such as electrical or mechanical needs, shall
be paid for by Tenant and arranged between such Tenant contractor and Landlord or Landlord’s contractor. Should the work
of any Tenant contractor depend on the installed field conditions of any item of Landlord’s Work, such Tenant contractor
shall ascertain such field conditions after installation of such item of Landlord’s Work. Neither Landlord nor Landlord’s
contractor shall ever be required or obliged to alter the method, time or manner for performing Landlord’s or work elsewhere
in the Building, on account of the work of any such Tenant contractor. Tenant shall cause each Tenant contractor performing
work on the Premises to clean up regularly and remove its debris from the Premises and Building.

5.

Tenant Delays. For purposes of this Exhibit C, "Tenant Delays" shall mean any delay in the completion of

Landlord’s Work resulting from any or all of the following: (a) any work by Tenant performed under Section 4 above
(provided that Landlord notifies Tenant reasonably promptly after such act that results in a Tenant Delay); (b) Tenant's
request for materials, finishes, work, equipment or installations (i) which are not readily available, or (ii) which vary from
the Building Standard, Baseline Plans, Approved Plans or are otherwise incompatible with the Building and any Building
Systems or which are inconsistent with the Approved Plans (provided that Landlord notifies Tenant that such request may
result in a Tenant Delay); (c) any Change and/or any Tenant’s request for any Changes (in all events, including without
limitation, (i) the time necessary for Landlord to review and evaluate any requested Change (regardless if the same is
approved by Landlord), (ii) the time necessary for Landlord to modify, undo, demolish or reverse, as applicable, any work
previously performed by Landlord (including any such work performed prior to the date hereof with respect to any Change
requested prior to the date hereof) as necessary to effect a Change, (iii) any necessary design and engineering time to effect
the Change, and (iv) any stoppage of Landlord’s Work while the parties determine whether to proceed with a Change); (d)
any delay of Tenant in making payment to Landlord for any amounts required to be paid by Tenant under this Exhibit C; (e)
the delays set forth in any Cost/Time Estimate, which Cost/Time Estimate shall include an estimate of any delays described
in subsections (b) and (c), above) (provided, that upon final completion of the Landlord’s Work required by a Change, the
actual delays on account thereof (whether more or less than the estimate in the Cost/Time Estimate) shall be deemed to be
the Tenant Delays for all purposes of the Lease); or (f) any other act or, where Tenant has a duty to act, failure to act by
Tenant, Tenant's employees, agents, architects, independent contractors, consultants and/or any other person performing or
required to perform services on behalf of

C-4

Tenant, including without limitation, any delay in Landlord’s Work caused by Tenant’s fit-out of the Premises prior to the
Commencement Date, provided that Landlord notifies Tenant reasonably promptly after such act or failure that a Tenant
Delay may result and provides Tenant with a reasonable estimate of such Tenant Delay.

If Landlord is delayed in achieving Substantial Completion of the Landlord’s Work as a result of any Tenant Delay
(including without limitation, on account of any Changes), the Substantial Completion Date and the Commencement Date
(in each case solely for purposes of determining the commencement of payments of Base Rent, Additional Rent (including
without limitation, Escalation Charges), determining the applicability of the penalties set forth in Section 2 above and the
expiration of the Term) shall be deemed advanced by the number of days of Tenant Delay experienced by Landlord to
Substantially Complete the Landlord’s Work. Tenant hereby acknowledges that but for any Tenant Delay (including without

Period”). The Base Rent due for any partial calendar month immediately following the Base Rent Abatement
Period shall be prorated based on the number of days in that month. In no event shall the Base Rent Abatement
Period be deemed to reduce or eliminate Tenant’s obligation to pay Additional Rent or any other amounts due
hereunder other than Base Rent. If Tenant defaults under this Lease prior to the expiration of the four month
period, then Tenant’s right to abate the Base Rent shall immediately terminate and be of no further force and
effect and any and all Base Rent which had been abated prior to Tenant’s default shall immediately become due
and payable.

2.
THE PREMISES. Landlord leases to Tenant, and Tenant leases from Landlord, upon and subject to the
terms and conditions of this Lease, the Premises. The Premises are leased with the right of Tenant to use for its
customers,  employees  and  visitors,  in  common  with  other  parties  entitled  thereto,  such  common  areas  and
facilities as Landlord may from time to time designate and provide, including without limitation the Amenities
(as  defined  below)  parking  and  loading  areas  and  elevators  serving  the  Premises  (collectively,  the  “Common
Areas”). Tenant shall have the right to use the conference facilities, fitness room, and grab-and-go café located
in the Common Areas as of the date of this Lease, or reasonable replacement for the same in the Building or on
the  Property  (the  “Amenities”)  and  Landlord  shall  make  such  Amenities,  or  reasonably  equivalent  amenities,
available for the duration of the term, subject to the terms of this Lease regarding casualty and Force Majeure,
and for temporary shutdowns in connection with renovations or modifications to the same.

TERM. The Premises are leased for the Term, unless such Term is sooner terminated. If for any reason

3.
Landlord is unable to deliver possession of the Premises to Tenant on or prior to

4

the  Estimated  Commencement  Date,  which  date  shall  be  extended  in  the  event  of  Tenant  Delay  and/or  Force
Majeure, then Landlord shall not be liable to Tenant for any resultant loss or damage and this Lease shall not be
affected except that the Base Rent Abatement Period shall be extended by one (1) day for each day of such delay
in  excess  of  30  days  until  the  Commencement  Date  actually  occurs  and,  if  the  Premises  are  not  delivered  to
Tenant by twelve (12) months after Landlord’s written approval of the Site Plan (as defined in the Work Letter) in
accordance  with  the  Work  Letter,  subject  to  extension  for  Tenant  Delay  and  Force  Majeure  or  eighteen  (18)
months after Landlord’s written approval of the Site Plan (as defined in the Work Letter) in accordance with the
Work Letter regardless of Force Majeure, then Tenant shall have the right to terminate the Lease upon 30 days’
prior  written  notice  to  Landlord  (but  if  the  Commencement  Date  occurs  within  such  30  day  period,  then  such
termination notice shall be null and void). The Base Rent Abatement Period shall not be extended for any delay
caused  by  a  Tenant  Delay  (as  defined  in  the  Work  Letter)  or  that  arises  as  a  result  of  any  Force  Majeure  (as
defined  below)  event.  Tenant  shall  have  the  option  to  extend  the  Term  subject  to  the  terms  and  conditions  of
Exhibit B attached hereto.

4.
CONDITION  OF  THE  PREMISES.  The  Premises  are  leased  in  an  “as  is”  and  “where  is”  condition
without any warranty of fitness for use or occupation express or implied, it being agreed that Tenant has had an
opportunity to examine the condition of the Premises, that Landlord has made no representations or warranties of
any kind with respect to such condition, and that Landlord has no obligation to do or approve any work or make or
approve any improvements to or with respect to the Premises in order to prepare the same for Tenant’s occupancy
except as specifically provided in this Section.

Landlord shall make improvements to the Premises as described in the Work Letter attached as Exhibit E.

MONTHLY RENT. Commencing on the Commencement Date (but subject to the Base Rent Abatement
5.
Period),  Base  Rent  shall  be  paid  monthly  in  advance  on  or  before  the  first  day  of  each  calendar  month  in
accordance with the schedule set forth in Section 1. The Base Rent shall not be adjusted or modified if the actual
rentable square footage of the Premises varies from the rentable square footage set forth in Section 1. If the Base
Rent Abatement Period shall expire on any day other than the first day of a calendar month, Base Rent for the
partial  month  shall  be  prorated  based  on  the  number  of  days  in  that  month.  Unless  otherwise  provided  herein,
commencing on the Commencement Date, Additional Rent shall be paid monthly in advance on or before the first
day of each calendar month. Additional Rent for any partial month shall be prorated based on the number of days
in that month. Rent shall be paid to Landlord, without notice or demand, and without deduction or offset, in lawful
money  of  the  United  States  of  America,  at  Landlord’s  Remittance  Address  as  set  forth  in  Section  1  or  to  such
other address as Landlord may from time to time designate in writing by at least 30 days’ prior notice to Tenant.
Tenant  acknowledges  that  the  late  payment  of  Rent  or  other  sums  due  hereunder  shall  cause  Landlord  to  incur
costs not contemplated by this Lease, the exact amount of which shall be extremely difficult to ascertain. Such
costs include, but are not limited to, processing and accounting charges, and late charges which may be imposed
on Landlord by the terms of any mortgage or trust deed covering the Property. Accordingly, if any installment of
Rent or any other sums due from Tenant shall not be received by Landlord within five (5) days after the same is
due (provided that on the

5

first occasion in any 12 month period Tenant shall be entitled to notice of such late payment and 10 days to cure
the same before such late charge shall apply) , Tenant shall pay to Landlord a late charge equal to five percent
(5%) of such overdue amount. In addition, any amount due to Landlord, if not paid within five (5) days after the
same  is  due,  shall  bear  interest  from  the  date  due  until  paid  at  the  lesser  of:  (i)  the  Prime  Rate  (as  hereinafter
defined) plus five percent (5%) per annum, or (ii) the highest rate permitted by law (the “Default Rate”). The term
“Prime Rate” shall mean the Prime Rate as published in The Wall Street Journal from time to time. The parties
agree that such late charges represent a fair and reasonable estimate of the costs Landlord shall incur by reason of
late payment by Tenant. The acceptance of such late charges by Landlord shall in no event constitute a waiver of
Tenant’s default with respect to the overdue amount, be deemed an accord and satisfaction, or prevent Landlord
from exercising any of the other rights and remedies granted hereunder. Notwithstanding anything to the contrary
in this Lease, Tenant shall pay the first full monthly installment of Base Rent due hereunder (i.e. Base Rent for the
first complete month of the Term, or, if applicable, for the first complete month following any initial abatement
period) simultaneously with Tenant’s execution and delivery of this Lease to Landlord.

6.
TAXES.  Tenant  shall  pay  monthly,  as  Additional  Rent,  one-twelfth  (1/12)  of  the  Tax  Excess  based  on
reasonable estimates provided by Landlord from time to time and subject to reconciliation as provided in Section
8 below. No credit or payment shall be due to Tenant in the event Taxes for any year are less than Base Taxes.
“Taxes” means all taxes, assessments and fees levied upon the Property by any governmental entity based upon
the ownership, leasing, renting or operation of the Property. Landlord shall equitably allocate Taxes incurred with
respect to multiple buildings on the Property, if any, among such buildings based on the relative assessed values of
such  Buildings  as  evidenced  by  the  assessors’  records  for  the  Town  of  Lexington.  Taxes  shall  not  include  any
federal, state or local net income, capital stock, succession, transfer, replacement, gift, estate or inheritance taxes;
provided,  however,  if  at  any  time  during  the  Term,  a  tax  or  excise  on  income  is  levied  or  assessed  by  any
governmental entity in lieu of or as a substitute for, in whole or in part, real estate taxes or other ad valorem taxes,
such tax shall constitute and be included in Taxes but only to the extent calculated as if the Property were the only
real estate owned by Landlord. In addition to the foregoing, Tenant shall pay Landlord, as Additional Rent, for
any use, rent or sales tax, service tax, value added tax, franchise tax or any other tax on Rent however designated
as well as for any taxes which are reasonably attributable to the cost or value of Tenant’s equipment, furniture,
fixtures and other personal property located in the Premises or the cost or value of any leasehold improvements
made  in  or  to  the  Premises  by  or  for  Tenant  if  the  same  are  separately  assessed  on  the  tax  bills  received  by
Landlord  and  all  tenants  in  the  Building  are  similarly  separately  charged  for  the  taxes  on  their  leasehold
improvements.  All  expenses,  including  reasonable  attorneys’  fees  and  disbursements,  experts’  and  other
witnesses’ fees, incurred in contesting the validity or amount of any Taxes or in obtaining a refund of Taxes shall
be considered as part of the Taxes for the year in which the expenses are incurred. Taxes shall exclude any interest
or penalties resulting from the late payment of Taxes by Landlord (except to the extent due to Tenant’s failure to
make timely payments), transfer taxes; any environmental assessments, charges or liens arising in connection with
the remediation of Hazardous Materials from the Building or Property; costs or fees payable to public authorities
in  connection  with  any  future  construction  of  additional  buildings  or  similar  improvements  on  the  Property
(including any such fees for transit, housing, schools, open space, child care, arts programs, traffic mitigation

6

measures,  environmental  impact  reports  and  traffic  studies);  reserves  for  future  Taxes;  Taxes  on  other  tenant’s
leasehold improvements; and any personal property taxes attributable to sculptures, paintings or other objects of
art. Taxes for any other structures or improvements on the Property (besides the Building) shall be allocated to
those structures or improvements on a proportionate basis based on square footage or such other method as is used
by the Town of Lexington tax assessor as evidenced by the tax bill for the Property.

7.
OPERATING  EXPENSES.  Tenant  shall  pay  monthly,  as  Additional  Rent,  one-twelfth  (1/12)  of  the
Operating Expenses Excess based on reasonable estimates provided by Landlord from time to time and subject to
reconciliation as provided in Section 8 below. No credit or payment shall be due to Tenant in the event Operating
Expenses  for  any  year  are  less  than  Base  Operating  Expenses.  “Operating  Expenses”  means  and  includes  all
expenses,  costs,  fees  and  disbursements  paid  or  incurred  by  or  on  behalf  of  Landlord  for  owning,  managing,
operating,  maintaining,  improving,  servicing  or  repairing  the  Building  or  Property  and  all  associated  plumbing,
heating,  ventilation,  air  conditioning,  lighting,  electrical,  mechanical  and  other  systems,  including,  without
limitation,  costs  of:  performing  the  Landlord’s  obligations  described  in  Section  13;  the  repair,  maintenance,
repaving and re-striping of any parking; providing any services or amenities such as conference rooms, parking
garage, cafeteria, or gymnasium; security costs for the Building and the Property; exterior maintenance, repair and
repainting; landscaping; snow removal; electricity charges; all other utilities; janitorial services for the common
areas  of  the  Property;  capital  repairs,  replacements  and  improvements,  management  fees  not  to  exceed  3%  of
gross  revenues  from  the  Building;  supplies  and  sundries;  sales  or  use  taxes  on  supplies  or  services;  charges  or
assessments under any easement, license, declaration, restrictive covenant or association of record as of the date
hereof;  accounting  expenses;  Insurance  Premiums;  and  compensation  and  all  fringe  benefits,  worker’s
compensation  insurance  premiums  and  payroll  taxes  paid  to,  for  or  with  respect  to  all  persons  engaged  in  the
operation, administration, maintenance and repair of the Property. The costs of capital repairs, replacements and
improvements, together with any actual out of pocket interest incurred to finance the same with third party debt,
where applicable, shall  be  amortized  over  their  useful  life  as  reasonably  determined by Landlord in accordance
with generally accepted accounting principles. Landlord shall equitably allocate any item of Operating Expenses
that benefits multiple buildings on the Property among such buildings. Landlord shall equitably allocate any item
of Operating Expenses among different portions or occupants of the Building or Property based on use where such
use  is  not  general  office  use,  or  other  considerations  as  reasonably  determined  by  Landlord  in  Landlord’s
reasonable discretion.

Notwithstanding the foregoing, Operating Expenses shall not include costs of alterations to the premises of other
tenants  of  the  Property,  depreciation  charges,  interest  and  principal  payments  on  mortgages,  ground  rental
payments and real estate brokerage and leasing commissions; costs incurred for Landlord’s general overhead and
any  other  expenses  not  directly  attributable  to  the  operation  and  management  of  the  Building  or  the  Property;
janitorial services for the Premises (which is a cost included in the Base Rent) or the premises of any other tenant
of the Property; costs of selling or financing any of Landlord’s interest in the Property; management fees incurred
by Landlord that are in excess of three percent (3%) of the gross revenues realized by Landlord from the Property;
costs incurred by Landlord for the repair of damage to the Property to the extent that Landlord is reimbursed by
insurance proceeds; and the costs of services and utilities separately

7

chargeable to individual tenants of the Building; salaries of executives and owners not directly employed in the
management/operation  of  the  Property  or  above  the  level  of  property  manager;  the  cost  of  services  for  any
particular tenant that are not available to Tenant or that are consumed or supplied to such tenant in excess of those
provided to Tenant; the cost of items that, by generally accepted accounting principles, would be capitalized on
the books of Landlord or are otherwise not properly chargeable against income, except to the extent such capital
item is (A) required by any applicable laws enacted after the Commencement Date, or (B) reasonably projected
and  determined  by  Landlord  and  its  engineers,  design  professionals  and/or  other  professionals  in  good  faith  to
reduce Operating Expenses, in each case amortized as provided above; the costs of Landlord’s Work (including
any  costs  to  correct  defects  in  the  Landlord’s  Work);  Taxes  or  items  expressly  excluded  from  Taxes;  Insurance
Premiums  for  insurance  coverages  not  typically  carried  by  first  class  office  buildings  in  the  vicinity  of  the
Property; costs allocable to any other building or Property; costs relating to maintaining Landlord’s existence as a
corporation, partnership or other entity; advertising and other fees and costs incurred in procuring tenants; the cost
of any items for which Landlord is entitled to be reimbursed by any third party (other than as Operating Expenses
by other tenants), including via insurance, condemnation awards, refund, rebate or otherwise, and any expenses

connection with any disputes between Landlord and its employees, between Landlord and Building management,
or between Landlord and other tenants or occupants; accounting fees; fines and penalties; costs and expenses of
investigating,  monitoring  or  remediating  existing  Hazardous  Materials  on,  under  or  about  the  Building  or  the
Property;  charitable  or  political  contributions;  all  items  and  services  for  which  Tenant  is  separately  charged  or
reimburses Landlord; reserves of any kind; the costs of goods and services provided by affiliates of Landlord, to
the extent only that the costs of such goods and/or services exceed competitive costs of such goods or services
provided by unrelated third parties; costs incurred, and increases in costs resulting from, the redevelopment of the
Building  or  the  development  and  construction  of  additional  structures  on  the  Property  (including  without
limitation any future development); the cost of acquiring and maintaining sculptures, paintings and other objects
of art; and the cost of advertising or promotion of (a) the Property or any part thereof or (b) any operations at the
Property; and costs to operate any concessions or amenities at the Property that are not available to Tenant (and in
any event after deducting any revenues received for use of the same).

8.
RECONCILIATION.  Any  failure  by  Landlord  to  deliver  any  estimate  or  statement  of  Additional  Rent
required  under  this  Lease  shall  not  operate  as  a  waiver  of  Landlord’s  right  to  collect  all  or  any  portion  of
Additional Rent due hereunder, except that failure to bill Tenant for any Operating Expenses or Taxes more than
two (2) years following the year in which they were incurred shall be deemed a waiver of the same. On an annual
basis,  within  180  days  following  the  expiration  of  each  calendar  year  during  the  Term,  Landlord  shall  provide
Tenant with a statement of all actual Operating Expenses and Taxes for the preceding year. If Tenant has made
estimated  payments  of  Operating  Expenses  or  Taxes  in  excess  of  the  actual  amount  due,  Landlord  shall  credit
Tenant with any overpayment against the next Rent otherwise due, provided, however, if such overpayment occurs
within  or  after  the  final  year  of  the  Term,  then  Landlord  shall  reimburse  Tenant  in  the  amount  of  such
overpayment  in  cash  as  part  of  Landlord’s  reconciliation  procedure  at  the  end  of  the  Term  and  such  obligation
shall survive the expiration or earlier termination of this Lease. If the actual amount due exceeds the estimated
payments made by Tenant during the

8

preceding  year,  Tenant  shall  pay  the  difference  to  Landlord  within  thirty  (30)  days  and  such  obligation  shall
survive the expiration or earlier termination of this Lease.

Tenant shall have the right during the Term, by providing written notice to Landlord (the “Review Notice”) within
sixty (60) days after receiving Landlord’s statement of actual Operating Expenses and Taxes, to review Landlord’s
records relating to Operating Expenses and Taxes for such year. Within a reasonable period of time after receipt of
a timely Review Notice, Landlord shall make such records available for Tenant’s review by electronic means or at
either  Landlord’s  home  office  or  at  the  office  of  the  property  manager  for  the  Building.  If  Tenant  fails  to  give
Landlord  written  notice  stating  in  reasonable  detail  any  objection  to  Landlord’s  statement  of  actual  Operating
Expenses within forty-five (45) days after such records are made available to Tenant for review then Tenant shall
be  deemed  to  have  approved  Landlord’s  statement  of  Operating  Expenses  for  such  year  (absent  manifest  error)
and  Tenant  shall  have  no  further  right  to  object  or  contest  such  statement.  Upon  Landlord’s  receipt  of  a  timely
objection notice from Tenant, Landlord and Tenant shall work together in good faith to resolve the discrepancy
between Landlord’s statement and Tenant’s review. If Landlord and Tenant determine that Operating Expenses for
the year in question are less than reported in Landlord’s statement, Landlord shall provide Tenant with a credit
against future Rent in the amount of any overpayment by Tenant, provided, however, if after the final year of the
Term, then Landlord shall reimburse Tenant in the amount of such overpayment in cash and such obligation shall
survive  the  expiration  or  earlier  termination  of  this  Lease.  Likewise,  if  Landlord  and  Tenant  determine  that
Operating  Expenses  for  the  year  in  question  are  greater  than  reported  in  Landlord’s  statement,  Tenant  shall
forthwith pay to Landlord the amount of underpayment by Tenant. Any information obtained by Tenant pursuant
to the provisions of this section shall be treated as confidential and Landlord may require that Tenant execute a
reasonable confidentiality agreement as a condition of Tenant’s review (provided that Tenant shall be entitled to
share  any  such  information  with  its  agents,  attorneys  and  consultants  provided  that  it  instructs  them  of  the
confidential information and is responsible for any unpermitted disclosure of the same). If Tenant retains an agent
to review Landlord’s books and records for any year, such agent must (i) be a CPA firm or professional real estate
services firm with experience in conduction of such audits (ii) not be compensated on a contingency basis, and
(iii) execute a reasonable confidentiality agreement with respect to such review. Tenant shall be solely responsible
for all costs incurred by Tenant in connection with such review unless such review reveals an overcharge of more
than  5%,  in  which  case  Landlord  shall  reimburse  Tenant  for  the  reasonable  out  of  pocket  costs  of  such  review.
Notwithstanding anything herein to the contrary, Tenant shall not be permitted to review Landlord’s records or to
dispute any statement of Operating Expenses if Tenant is in default or if Tenant has not first paid to Landlord the
amount due as shown on Landlord’s statement of actual Operating Expenses.

(A)
Tenant  shall  maintain  the  following  insurance  in  force  from  the  date  upon  which  Tenant  first  enters  the

Premises:

(i)

Commercial General Liability insurance with limits of at least $1,000,000 per occurrence,

liability;

(ii) Worker’s Compensation insurance as required by the state in which the Premises is located

$500,000 disease;

(iii)

Business Automobile Liability insurance for all owned (Symbol 1), non-owned (Symbol 9)

policy shall include a combined single limit of liability of at least $1,000,000 per claim for bodily injury
and property damage and shall provide that employees are insureds;

(iv)

Excess or Umbrella Liability insurance with a limit of at least $5,000,000 providing

additional limits of insurance over the primary per occurrence and aggregate limits of the Commercial
General Liability (including bodily injury, property damage, products/completed operations,

Liability insurance required in (i), (ii), and (iii) above;

(v)

Property insurance covering “all risk” of physical damage to Tenant’s personal property and

indirect physical damage to all Alterations made by Tenant to the Premises. Such coverage shall be for the
full replacement value of the covered property; and

(vi)

Business interruption insurance with a limit of liability representing loss of at least

approximately twelve (12) months of rent.

(B)
Tenant’s  Commercial  General  Liability,  Property,  and  Excess  Liability/Umbrella  Liability  policies  shall
name  Landlord,  Landlord’s  managing  agent,  and  Landlord’s  mortgagee  as  Additional  Insureds  and  shall  be
primary  insurance  as  to  any  insurance  carried  by  the  parties  designated  as  Additional  Insureds.  All  policies
purchased  and  maintained  by  Tenant  to  satisfy  the  requirements  in  this  Lease  must  be  purchased  from  an
insurance company with a minimum rating of “A- VII” or its equivalent from one of the major rating agencies
(AM  Best,  Moodys,  Standard  &  Poors,  Fitch)  that  is  admitted  or  eligible  to  do  business  in  the  state  where  the
Premises is located.

(C)
Tenant shall provide Landlord with a certificate of insurance for each policy prior to entering the Premises
and at least thirty (30) days prior to each renewal of such insurance. Such certificates of insurance shall be on an
ACORD Form 27 or ISO Form 2026 or their equivalent, shall certify that such policy has been or shall be issued
and  that  it  provides  the  coverage  and  limits  required  above,  and  Tenant  shall  endeavor  to  provide  that  the
insurance shall not be canceled or materially changed unless thirty (30) days prior written notice shall have been
given to Landlord and, if such insurer will not provide such notice, Tenant shall provide Landlord with 30 days’

10

notice of cancellation or any material change that would cause non-compliance with the provisions of this Section
9.  In  addition  to  providing  the  certificates  of  insurance  required  herein,  Tenant  shall  also  promptly  furnish  any
reasonable additional information which may include policies in the event of an actual claim for personal injury or
property  damage  (and  Landlord  shall  provide  Tenant  with  copies  of  its  insurance  policies  in  such  event),  as
Landlord may request from time to time pertaining to Tenant’s insurance coverage. Tenant shall notify Landlord in
writing  as  soon  as  practicable  if  Tenant  receives  a  notice  that  its  insurance  company  intends  to  cancel  or  non-
renew  such  insurance  for  any  reason,  or  if  the  required  coverage  or  limits  are  to  be  materially  and  adversely
changed from the initial requirements in this Lease. In the event that the applicable statutory time period is less
than  sixty  (60)  days,  then  Tenant  shall  notify  Landlord  within  three  (3)  business  days  of  receipt  of  any
cancellation or non-renew notice. In the event that Tenant fails to obtain or maintain the insurance required above
or  fails  to  provide  the  Certificates  of  Insurance  required,  Landlord  may,  at  its  option,  upon  five  days’  notice  to
Tenant,  obtain  such  insurance  on  behalf  of  Tenant.  Tenant  shall  pay,  as  Additional  Rent  upon  demand,  the
reasonable cost of such insurance plus a 10 %) surcharge. Landlord’s failure to obtain such coverage on behalf of
Tenant shall not limit Tenant’s liability in the event of an uncovered loss.

(D)
 Landlord shall carry or cause to be carried such insurance in amounts and with deductibles as a reasonably
prudent  landlord  would  purchase  and  maintain  with  respect  to  the  Property,  including  without  limitation
replacement  cost  insurance  on  the  Building  and  any  tenant  improvements  in  the  Premises.  Tenant  shall  pay
Tenant’s Percentage of Landlord’s insurance premiums (“Insurance Premiums”) during the Term of the Lease as a
part of Operating Expenses. Tenant shall not do or permit to be done anything which shall contravene, invalidate,
or increase the cost of the Landlord’s insurance and shall comply with all rules, orders, regulations, requirements
and  recommendations  of  Landlord  or  its  insurance  companies  relating  to  or  affecting  the  condition,  use,  or
occupancy  of  the  Premises.  If  Tenant  does  conduct  any  activity  within  or  about  the  Premises  that  results  in  an
increase  to  the  cost  of  Landlord’s  insurance  Tenant  shall  reimburse  Landlord  for  the  entire  amount  of  such
additional premiums or surcharges within 30 days following demand.

10. WAIVER  OF  SUBROGATION.  Notwithstanding  any  other  language  of  this  Lease  to  the  contrary,
Landlord and Tenant each waive their respective rights to recover from the other for any and all loss of or damage
to  their  respective  property  if  such  loss  or  damage  is  covered,  or  required  by  this  Lease  to  be  covered,  by
insurance.  Each  party  shall  obtain  an  endorsement  acknowledging  such  waiver  from  its  insurance  company(s)
evidencing compliance with this Section .

11.
SECURITY DEPOSIT. In lieu of a cash Security Deposit, Tenant shall deliver with executed copies of
this  Lease  a  letter  of  credit  (the  “Letter  of  Credit”)  substantially  in  the  form  of  Exhibit  G  attached  hereto  and
otherwise  acceptable  to  Landlord.  The  initial  Letter  of  Credit  must  be  issued  by  Bank  of  America  and  any
subsequent or replacement Letter of Credit shall be issued by a domestic bank reasonably acceptable to Landlord
whose deposits are insured by the FDIC. The Letter of Credit shall (i) be unconditional, irrevocable, transferable,
and payable to Landlord or Landlord’s agent solely upon presentment by Landlord or Landlord’s agent of a sight
draft in person, by courier, overnight mail, or by facsimile transmission in partial or full draws, and (ii)

11

contain  an  “evergreen”  provision  which  provides  that  it  is  automatically  renewed  on  an  annual  basis  unless  the
issuer  delivers  sixty  (60)  days’  prior  written  notice  of  cancellation  to  Landlord.  If  the  Letter  of  Credit  is  lost,
mutilated, stolen, or destroyed, Tenant shall cooperate with Landlord to have the Letter of Credit replaced at no
cost to Tenant. If the financial status of the Letter of Credit or its issuer is called into material question for any
reason,  including,  without  limitation,  if  the  issuer  fails  or  becomes  insolvent  or  is  placed  in  receivership,  or  its
financial rating is downgraded or any other event occurs which makes Landlord, in its sole discretion exercised in
good faith, insecure in its ability to rely on the Letter of Credit as security, then Tenant shall, within ten (10) days
following  Landlord’s  demand,  provide  to  Landlord  a  substitute  letter  of  credit  from  a  financial  institution
reasonably  acceptable  to  Landlord.  Tenant’s  failure  to  timely  provide  such  substitute  Letter  of  Credit  shall  be
deemed  an  immediate  Event  of  Default  for  which  no  additional  notice  or  grace  period  shall  apply.  Without
limiting any of Landlord’s rights or remedies hereunder, if the bank issuing the Letter of Credit provides Landlord
with a cancellation notice, Landlord may immediately draw upon all or any part of the Letter of Credit and Tenant
shall provide Landlord with a replacement letter of credit in similar form (at which time Landlord shall return any
such funds drawn to Tenant, to the extent not applied in accordance with this Lease). Any and all fees or costs
charged by the issuer in connection with the issuance, maintenance or transfer of the Letter of Credit shall be paid
by  Tenant.  The  Letter  of  Credit  shall  remain  effective  through  the  date  that  is  ninety  (90)  days  following  the
expiration  of  this  Lease  and  the  delivery  of  possession  of  the  Premises  to  Landlord  in  accordance  with  the
provisions of this Lease. If Tenant defaults with respect to any provision of this Lease beyond applicable notice
and cure periods, including without limitation the provisions relating to the payment of Rent, Landlord may, but
shall not be required to, draw upon all or any part of Tenant’s Letter of Credit to the extent necessary to cure such
default and to reimburse Landlord for any damages to which Landlord is entitled hereunder. If any of the proceeds
of the Letter of Credit are not applied to cure any default of Tenant or damages payable to Landlord, Landlord
promptly return the same to Tenant. If any portion of the Letter of Credit is drawn upon, Tenant shall cause the
Letter of Credit to be increased to the amount required as the Security Deposit under this Lease within ten (10)
days  after  written  demand  from  Landlord,  and  in  such  event,  provided  there  is  then  no  outstanding  default  by
Tenant, any proceeds of the Letter of Credit retained by Landlord as a cash Security Deposit and not applied to
cure any default shall be returned to Tenant. The Letter of Credit shall not operate as a limitation on any recovery
to which Landlord may be entitled. Provide that no default is then continuing beyond applicable notice and cure
periods,  and  Tenant  has  surrendered  the  Premises  in  accordance  with  this  Lease  upon  the  expiration  or  earlier
termination of this Lease, Landlord shall return the Letter of Credit and any cash proceeds then held by Landlord
therefrom to Tenant within 30 days following the expiration or earlier termination of this Lease.

12.
USE. The Premises shall be used for the Permitted Use and for no other purposes whatsoever. Tenant shall
not do or permit to be done in or about the Premises anything which is prohibited by any ordinance, order, rule,
regulation, certificate of occupancy, or other governmental requirement, now in force or which may hereafter be
enacted,  including,  without  limitation,  the  Americans  with  Disabilities  Act  of  1990,  as  amended  (collectively,
“Applicable Law”). Tenant shall comply with all Applicable Law in its use of the Premises and common areas of
the Property. Tenant shall use and cause all contractors, agents, employees, invitees and visitors of Tenant to use
the Premises and any common area of the Property in such a manner as to prevent

12

waste,  nuisance  and  any  disruption  of  other  occupants.  Tenant  shall  not  place  a  load  upon  any  floor  in  the
Premises  exceeding  the  floor  load  per  square  foot  of  area  which  such  floor  was  designed  to  carry  or  which  is
allowed by Applicable Law . Tenant shall, at Tenant’s sole cost and expense, make any changes necessary to bring
the Premises into compliance with any Applicable Law as a result of Tenant’s particular use, as opposed to office
use generally. The judgment of any court of competent jurisdiction or the admission by Tenant in any action or
proceeding  against  Tenant,  whether  Landlord  is  a  party  thereto  or  not,  that  Tenant  has  violated  any  Applicable
Law  in  the  use  or  occupancy  of  the  Premises,  Building  or  Property  shall  be  conclusive  of  that  fact  as  between
Landlord and Tenant. Notwithstanding anything to the contrary in this Lease, Landlord shall be responsible for the
compliance  of  the  Building  (other  than  to  the  extent  of  Tenant’s  repair  and  maintenance  obligations  within  the
Premises) with Applicable Laws, except to the extent resulting from Tenant’s particular use of the Premises (as
opposed to office use generally).

13. MAINTENANCE;  SERVICES.  Excepting  only  those  obligations  for  which  Landlord  is  expressly
responsible pursuant to this section, Tenant will, throughout the Term and at its sole cost, keep and maintain the
Premises and all Tenant-installed fixtures and equipment located therein, including, without limitation, carpeting,
wall-covering, doors, plumbing and other fixtures, and any Alterations performed for the benefit of the Premises,
clean  safe  and  in  good  working  order,  condition  and  repair  and  make  all  necessary  repairs  and  replacements
thereto, including, without limitation, replacing all interior broken glass with glass of the same size and quality as
that  broken  and  repairing  or  replacing  all  systems  or  portions  of  systems  installed  by  Tenant  and  exclusively
serving the Premises including, without limitation, supplemental heating, ventilating and air conditioning systems.
All  repairs  and  replacements  required  of  Tenant  in  connection  herewith  shall  be  of  a  quality  and  class  at  least
equal to the minimum building standards established by Landlord and shall be done in a good and workmanlike
manner  in  compliance  with  all  applicable  laws  and  the  terms  and  conditions  of  this  Lease.  If  Tenant  fails  to
maintain the Premises in compliance with the terms hereof beyond applicable notice and cure periods, Landlord
shall have the right to do such acts and expend such funds at the expense of Tenant as are reasonably required and
Tenant shall reimburse Landlord for the out of pocket cost thereof as Additional Rent upon demand. If Tenant uses
heat  generating  machines  or  equipment  in  the  Premises  that  materially  affect  the  temperature  otherwise
maintained by the heating, ventilating and air conditioning system, Landlord reserves the right to direct Tenant to
cease  such  use,  and  if  Tenant  does  not  cease  such  use,  to  install  supplementary  units  for  the  Premises  and  the
reasonable out of pocket cost thereof, including the out of pocket cost of installation, operation and maintenance,
shall  be  paid  by  Tenant  to  Landlord  as  Additional  Rent  upon  demand.  Should  Tenant  require  any  additional
service not provided by Landlord pursuant to this Lease, including any services furnished outside the Building’s
normal  business  hours,  Landlord  may,  but  shall  not  be  obligated  to,  furnish  such  additional  service  and  Tenant
agrees to pay Landlord’s charges therefor, including a reasonable administrative fee, any taxes imposed thereon,
and,  where  appropriate,  a  reasonable  allowance  for  depreciation  of  any  systems  being  used  to  provide  such
service, as Additional Rent upon demand.

Landlord shall maintain the roof and roof system, foundation, exterior walls and glass, structural portions,
elevators, if any, any common areas and electrical, plumbing, mechanical, life safety, and fire protection systems
(excepting only systems installed by or on behalf of Tenant

13

exclusive to the Premises) and Common Areas of the Building, the cost of which shall be included as a part of
Operating Expenses subject to the terms of this Lease, provided that Landlord shall have no obligation to make
any repairs unless Landlord has first received written notice of the need for such repairs from Tenant or Landlord
otherwise has notice of the same. Notwithstanding the foregoing, subject to Section 10 of this Lease, any damage
to  the  Property  occasioned  by  the  negligence  or  willful  misconduct  of  Tenant  or  any  person  claiming  under
Tenant, or contractors, agents, employees, invitees or visitors of Tenant or any such person, shall be repaired by
and at the sole expense of Tenant, except that Landlord shall have the right, at its sole option, to make such repairs
and  to  charge  Tenant  for  all  costs  and  expenses  incurred  in  connection  therewith  and  Tenant  shall  pay  the  cost
therefor as Additional Rent within 30 days following invoice. In addition to the foregoing, during normal hours of
operation of the Building throughout the Term, Landlord shall provide: (i) reasonable quantities of electricity for
the common areas and Premises; (ii) customary heating, ventilation and air conditioning for the comfortable use
and  occupancy  of  the  Premises  during  the  normal  hours  of  operation  of  the  Building;  (iv)  building  standard
window washing and janitorial services; (v) hot and cold water for drinking, cleaning, kitchenette and restroom
purposes only; (v) passenger elevator service to the floors on which the Premises is located (with accommodations
for customary office freight use in accordance with Building rules and regulations), (vi) removal of unreasonable
accumulations of snow and ice from walks and drives, (vii) access to the Premises and Common Areas serving the
same  24  hours  a  day,  7  days  a  week,  365  days  a  year,  and  (viii)  such  other  services  as  Landlord  reasonably
determines  are  necessary  or  appropriate,  all  in  a  manner  consistent  with  comparable  office  buildings  in  the
Lexington, Massachusetts area.

14.
SUBLEASE; ASSIGNMENT. Tenant shall not mortgage, pledge, hypothecate or otherwise encumber its
interest in this Lease. Tenant shall not allow the Premises to be occupied, in whole or in part, by any other party
and  shall  neither  sublet  the  Premises,  in  whole  or  in  part,  nor  assign  this  Lease,  nor  amend  any  sublease  or
assignment  to  which  Landlord  has  consented,  without  in  each  case  obtaining  the  prior  written  consent  of
Landlord.  Any  sublease  or  assignment,  or  amendment  to  any  sublease  or  assignment,  without  Landlord’s  prior
written consent where required hereunder shall, at Landlord’s option, be null, void and of no effect, and shall, at
Landlord’s option, constitute an Event of Default. The provisions of this section shall apply to a transfer, by one or
more transfers, of all, or substantially all, of the business or assets of Tenant, of a direct or indirect majority of the
stock, partnership or membership interests, or other evidences of ownership, of Tenant, and of any shares, voting
rights  or  ownership  interests  of  Tenant  which  results  in  a  change  in  the  identity  of  the  entity  or  entities  which
exercise, or may exercise, effective control of Tenant as if such transfers were an assignment of this Lease, but
shall  not  apply  to  any  other  transfers  of  interests  in  Tenant.  Tenant  must  request  Landlord’s  consent  to  any
assignment or sublease at least sixty (60) days prior to the proposed effective date of the assignment or sublease.
At  the  time  of  its  request,  Tenant  shall  provide  Landlord  in  writing:  (a)  the  name  and  address  of  the  proposed
assignee  or  subtenant,  (b)  a  complete  copy  of  the  proposed  form  of  assignment  or  sublease,  if  available,  (c)
reasonably satisfactory information about the nature, business, and business history of the proposed assignee or
subtenant and its proposed use of the Premises, and (d) banking, financial or other credit information about the
proposed  assignee  or  subtenant  sufficient  to  enable  Landlord  to  determine  its  financial  condition  and  operating
performance (provided that Landlord shall keep such information confidential to the extent that

14

Tenant is required to do the same). Landlord shall not unreasonably withhold, condition, or delay its consent to
Tenant’s written request to sublease the Premises or assign this Lease which is made in compliance with the terms
and conditions of this section. Without limiting the other instances in which it may be reasonable for Landlord to
withhold its consent to an assignment or sublease, Landlord’s refusal to consent to any proposed assignment or
sublease  shall  not  be  unreasonable  if:  (a)  the  financial  condition  or  operating  performance  of  the  proposed
subtenant (if the sublease is for all or substantially all of the Premises for all or substantially all of the remaining
term)  or  assignee,  determined  in  Landlord’s  reasonable  discretion,  is  less  than  the  greater  of  the  financial
condition or operating performance of the Tenant on (i) the date of Tenant’s request for Landlord’s consent to the
proposed assignment or sublease, (b) Tenant is in default under any of the terms, covenants or conditions of this
Lease, (c) the proposed use of the Premises may result in: (i) increased wear and tear on the Premises, Building or
Property or (ii) any adverse effect on other tenants in the Building or adjacent buildings owned by Landlord, (d)
the proposed subtenant or assignee is a governmental agency, (e) the proposed subtenant or assignee is a prospect
to  whom  Landlord  has  made  a  proposal  for  the  lease  of  space  within  the  market  area  within  the  prior  six  (6)
months, (f) the proposed assignee or subtenant is a tenant in any building owned by Landlord or any affiliate of
Landlord at the Property including, without limitation, the Building and Landlord or such affiliate has available
space for lease that meets the requirement of such subtenant or assignee, (g) the proposed subtenant or assignee
would  cause  Landlord  to  be  in  violation  of  any  covenant  or  restriction  contained  in  another  lease  or  other
agreement, and/or (h) Landlord’s lender, if any, does not consent to the proposed sublease or assignment, to the
extent that such consent is required under the applicable loan documents.

No  subletting  or  assignment  shall  release  Tenant  from  Tenant’s  obligations  under  this  Lease  or  alter  the
primary  liability  of  Tenant  to  pay  the  Rent  and  to  perform  all  other  obligations  to  be  performed  by  Tenant
hereunder. Any subtenant shall, at Landlord’s election, attorn to Landlord following any early termination of this
Lease and any assignee shall be jointly and severally liable for the full performance of all of Tenant’s obligations
hereunder. Landlord may require, as a condition to granting Landlord’s consent with respect to the provisions of
this  section,  that  the  proposed  subtenant  or  assignee  enter  into  a  reasonable  written  agreement  with  Landlord
confirming the obligations of such subtenant or assignee under this Lease. Tenant shall pay, as Additional Rent on
demand,  all  reasonable  out  of  pocket  legal  fees  incurred  by  Landlord  in  connection  with  each  proposed
assignment  or  sublease  whether  or  not  Landlord’s  consent  is  obtained  in  an  amount  not  to  exceed  $7,500  per
sublease or assignment. If Tenant receives rent or other payments under any assignment (to the extent reasonably
allocated  to  the  Lease)  or  sublease  (in  each  case  other  than  pursuant  to  a  Permitted  Transfer)  in  excess  of  the
payments made by Tenant to Landlord under this Lease (as such amounts are adjusted on a per square foot basis if
less than all of the Premises is transferred), after deducting the reasonable out of pocket costs incurred by Tenant
in connection with such sublet or assignment, then Tenant shall pay Landlord one-half of such excess when paid
by such assignee or subtenant. Landlord’s consent to one assignment or sublease shall not be deemed a waiver of
the  requirement  of  Landlord’s  consent  to  any  subsequent  assignment  or  sublease.  In  the  event  Tenant  seeks  to
assign its interest in this Lease (other than with respect to a Permitted Transfer), and Landlord does not consent to
such proposed assignment, Landlord may, within ten (10) days following delivery to Landlord of Tenant’s request
to assign the Lease, elect to terminate this Lease in its entirety, and the last day

15

of the Term of this Lease shall be the thirtieth (30th) day after Landlord notifies Tenant of Landlord’s election to
terminate this Lease unless Tenant rescinds its request to consent to such assignment within such 30 day period. In
the event Tenant seeks to sublet all or any portion of the Premises (other than with respect to a Permitted Transfer)
and  Landlord  does  not  consent  to  such  proposed  sublease,  within  10  days  followings  delivery  to  Landlord  of
Tenant’s request to sublet this Lease, Landlord may elect to terminate this Lease with respect to the portion of the
Premises  that  would  be  subject  to  such  sublease  (provided  that  such  portion  consists  of  at  least  33%  of  the
Premises) and the last day of the Term of this Lease for such space shall be the thirtieth (30th) day after Landlord
notifies  Tenant  of  Landlord’s  election  to  terminate  this  Lease  (and,  if  less  than  the  entire  Premises  is  affected,
Landlord shall perform any alterations to make such space a self-contained rental unit) unless Tenant rescinds its
request to consent to such sublease within such 30 day period.

Notwithstanding anything to the contrary in this Lease, Tenant may, from time to time and at any time with
at  least  30  days’  prior  written  notice  to  Landlord  (unless  such  notice  is  prohibited  pursuant  to  a  confidentiality
agreement negotiated at arms-length and not in avoidance of the provisions of this paragraph in which case such
notice shall be provided  within  10  business  days  following  such  transfer),  make the following assignments and
sublets  without  the  need  for  the  prior  consent  of  Landlord  (any  of  the  following,  a  “Permitted  Transfer”):  (1)
Tenant may assign the Lease, sublet, or otherwise permit the occupancy of any portion of the Premises by person
or entity that controls Tenant, is controlled by Tenant or is under common control with Tenant; (2) Tenant may
assign  the  Lease  to  a  successor  entity  in  connection  with  the  merger  or  consolidation  of  Tenant  and  such  other
entity or to the purchaser or transferee of all or substantially all of the business and assets of Tenant, provided that
the  tangible  net  worth  (computed  in  accordance  with  generally  accepted  accounting  principles,  consistently
applied) (the “Net Worth”) of Tenant is not materially reduced as a result of such transfer below the Net Worth of
the Tenant as of the date of such transfer; and/or (2) Tenant may permit occupancy of a portion of the Premises
(not to exceed 5% in the aggregate at any one time) under a revocable license to any individual or entity providing
professional  services  to  Tenant  or  any  entity  under  common  control  with  Tenant  in  connection  with  the
performance of such services. Any such Permitted Transfer shall not relieve Tenant of its obligations under this
Lease.

15.
INDEMNITY;  NON-LIABILITY  OF  LANDLORD.  Except  to  the  extent  prohibited  by  law,  as  a
material part of the consideration for Landlord’s execution of this Lease or otherwise resulting from Landlord’s or
its  agents,  contractor’s  or  employees  negligence  or  willful  misconduct,  Tenant  shall  neither  hold  nor  attempt  to
hold  Landlord  or  its  employees  or  Landlord’s  agents  or  contractors  or  their  employees  liable  for,  and  Tenant
covenants and agrees that it shall indemnify and defend Landlord for and against any and all penalties, damages,
fines, causes of action, liabilities, judgments, expenses (including, without limitation, attorneys’ fees) or charges
incurred  in  connection  with  or  arising  from:  (i)  the  use  or  occupancy  of  the  Premises  by  Tenant  or  any  person
claiming  under  Tenant;  (ii)  any  negligent  acts  or  omissions  of  Tenant  or  any  person  claiming  under  Tenant,  or
contractors,  agents,  employees,  invitees  or  visitors  of  Tenant  or  any  such  person;  (iii)  any  breach,  violation  or
nonperformance by Tenant or any person claiming under Tenant or the employees, agents, contractors, invitees or
visitors of Tenant or any such person of

16

any  law,  ordinance  or  governmental  requirement  of  any  kind  in  connection  with  this  Lease;  or  (v)  any  matter
occurring in the Premises during the Term.

Except  to  the  extent  resulting  from  Landlord’s  or  its  agents,  contractor’s  or  employees  negligence  or
willful  misconduct,  Landlord,  to  the  fullest  extent  not  prohibited  by  law,  shall  not  be  liable  for  any  damage
occasioned by failure to keep the Premises, Building or Property in repair, nor for any damage done or occasioned
by  or  from  plumbing,  gas,  electricity,  water,  sprinkler,  or  other  pipes  or  sewerage  or  the  bursting,  leaking  or
running of any pipes, tank or plumbing fixtures, in, above, upon or about the Premises or the Building nor from
any  damage  occasioned  by  water,  snow  or  ice  being  upon  or  coming  through  the  roof,  skylights,  trap  door  or
otherwise, nor for any damages arising from acts, or neglect of co-tenants or other occupants of the Building or of
any owners or occupants of adjacent or contiguous property, nor for any loss of or injury to property or business
occurring, through, in connection with or incidental to the failure to furnish any such services or the interruption
of  any  services  to  the  Premises.  Further,  Landlord  shall  not  be  liable  or  responsible  to  Tenant  for  any  loss  or
damage to any property or person occasioned by theft or any other criminal act, fire, act of God, public enemy,
injunction, riot, strike, insurrection, war, court order, law of requisition or order of any governmental authority.

Except as otherwise expressly set forth in this Lease, neither party under this Lease shall be liable to the
other  in  any  event  for  incidental  or  consequential  damages  to  the  other  by  reason  of  any  default  hereunder,
whether or not such party is notified that such damages may occur. The term “Landlord”, as used in this Lease, so
far as covenants or obligations to be performed by Landlord are concerned, means only the owner or owners at the
time in question of the Landlord’s interest in the Building, and in the event of any transfer or transfers of title to
the Landlord’s interest in the Building and notice to Tenant of the same, the Landlord herein named (and in case of
any subsequent transfers or conveyances, the then grantor) shall be automatically released and relieved from and
after  the  date  of  such  transfer  or  conveyance  of  all  liability  as  respects  the  performance  of  any  covenants  or
obligations on the part of the Landlord contained in this Lease thereafter to be performed. Tenant’s sole recourse
against Landlord, and any successor to the interest of Landlord in the Premises, is to the interest of Landlord, and
any successor, in the Premises and the Building of which the Premises are a part and the proceeds therefrom. In no
event  whatsoever  shall  Landlord  or  any  beneficiary  of  any  trust  of  which  Landlord  is  a  trustee  or  any  of
Landlord’s officers, directors, partners, managers, members, shareholders, agents, attorneys and employees ever
be personally liable hereunder.

16.
UTILITIES. If any utility serving the Premises is not separately metered to the Premises, the cost of such
utility  consumed  on  the  Premises,  as  reasonably  determined  by  Landlord  based  on  the  reading  of  check  or
submeters, shall be paid by Tenant as Additional Rent to the extent not included in Operating Expenses. Landlord
and Tenant acknowledge that electricity is not separately metered as of the date hereof. As part of the Landlord’s
Work, but at Landlord’s sole cost and expense, the Premises shall be separately or check-metered for electricity
serving Tenant’s lights and plugs . Tenant’s obligation to pay for utilities provided to the Premises during the Term
shall survive the expiration or earlier termination of the Lease. Tenant shall not utilize an alternative provider for a
utility  service  other  than  the  public  utility  providers  servicing  the  Property  unless  Tenant  shall  first  obtain  the
written consent of Landlord. Landlord shall in no way

17

be  liable  or  responsible  for  any  loss,  damage,  or  expense  that  Tenant  may  sustain  or  incur  by  reason  of  any
change, failure, interruption, or defect in the supply or character of the electric energy furnished to the Premises or
Building.(collectively,  “Interruption”)  nor  shall  such  Interruption  constitute  or  be  construed  as  a  constructive  or
other eviction of Tenant. To ensure the proper functioning and protection of all utilities, Tenant agrees to abide by
all reasonable regulations and requirements which Landlord may prescribe and to allow Landlord and its utility
providers access to all electric lines, feeders, risers, wiring, and any other machinery within the Premises (subject
to Section 26)

Notwithstanding anything to the contrary in this Lease, if: (i) Landlord ceases to furnish any service in the
Building  due  to  a  condition  reasonably  within  the  control  of  Landlord  for  a  period  in  excess  of  ten  (10)
consecutive business days after Tenant notifies Landlord of such cessation (the “Interruption Notice”); (ii) such
cessation does not arise as a result of an act or omission of Tenant; (iii) such cessation is not caused by a fire or
other casualty (in which case Section 19 shall control); and (iv) the restoration of such service is reasonably within
the control of Landlord; and (v) as a result of such cessation, a material (25% or more) portion of the Premises is
rendered  untenantable,  then  Tenant  shall  be  entitled  to  receive  an  equitable  abatement  of  Base  Rent  payable
hereunder during the period beginning on the eleventh (11th) consecutive business day, based on the proportion of
the  Premises  rendered  untenantable,  after  Landlord's  receipt  of  the  Interruption  Notice  and  ending  on  the  day
when the service in question has been restored. If any such interruption renders a substantial part of the Premises
untenantable  and  restoration  is  within  the  reasonable  control  of  Landlord  but  is  not  complete  within  180  days
following the Interruption Notice, then Tenant may terminate this Lease upon 30 days’ prior written notice

HOLDING  OVER.  If  Tenant  or  any  party  claiming  by  or  under  Tenant  remains  in  occupancy  of  the
17.
Premises or any part thereof beyond the expiration or earlier termination of this Lease, such holding over shall be
without right and a tenancy at sufferance, and following the 30th day of any such holdover Tenant shall be liable
to Landlord for any loss or damage incurred by Landlord as a result thereof, including consequential damages. In
addition,  for  each  month  or  any  part  thereof  that  such  holding  over  continues,  Tenant  shall  pay  to  Landlord  a
monthly fee for the use and occupancy of the Premises equal to the greater of (a) the monthly fair market rental
for the Premises and (b) one hundred fifty percent (150%) of the Base Rent payable for the month immediately
preceding such hold over for the first 30 days and two hundred percent (200%) thereafter, and there shall be no
adjustment  or  abatement  for  any  partial  month  (together  with  all  otherwise  applicable  payments  of  Additional
Rent). The provisions of this Section shall not be deemed to limit or exclude any of Landlord’s rights of re-entry
or any other right granted to Landlord hereunder, at law or in equity.

18.
NO RENT DEDUCTION OR SET OFF. Tenant’s covenant to pay Rent is and shall be independent of
each and every other covenant of this Lease. Tenant agrees that any claim by Tenant against Landlord shall not be
deducted  from  Rent  nor  set  off  against  any  claim  for  Rent  in  any  action.  No  payment  by  Tenant  or  receipt  by
Landlord of a lesser amount than the Rent herein stipulated shall be deemed to be other than on account of the
earliest  stipulated  Rent,  nor  shall  any  endorsement  or  statement  on  any  check  or  any  letter  accompanying  any
check or payment as Rent be deemed an accord and satisfaction, and Landlord may accept such check or payment
without

18

prejudice to Landlord’s right to recover the balance of such Rent or pursue any remedy provided in this Lease or
at law. In connection with the foregoing, Landlord shall have the absolute right in its sole discretion to apply any
payment received from Tenant to any account or other payment of Tenant then not current and due or delinquent.

19.
CASUALTY. If the Premises or any part thereof are damaged by fire or other casualty, Tenant shall give
prompt notice thereof to Landlord. If the Premises or the Building are totally or partially damaged or destroyed by
fire or other casualty, thereby rendering the Premises totally or partially inaccessible or unusable, Landlord shall
diligently restore and repair the Premises and the Building to substantially the same condition they were in prior to
such damage. Provided that such damage was not caused by the negligence, act or omission of Tenant or any of its
employees,  agents,  licensees,  invitees  or  subtenants  (but  subject  to  the  provisions  of  Section  10  of  this  Lease),
until the repair and restoration of the Premises is completed Base Rent shall be abated for that part of the Premises
that Tenant is unable to access or use without substantial interference and is not occupied while repairs are being
made, based on the ratio that the amount of unusable rentable area bears to the total rentable area of the Premises.
Landlord  shall  bear  the  costs  and  expenses  of  repairing  and  restoring  the  Premises  and  the  Building,  provided,
however, that Landlord shall not be obligated to spend more than the net proceeds of insurance proceeds made
available  for  such  repair  and  restoration  nor  shall  Landlord  be  obligated  to  repair  or  restore,  or  to  pay  for  the
repair or restoration of, any furnishings, equipment or personal property belonging to Tenant or any alterations,
additions,  or  improvements  (including  carpeting,  floor  coverings,  paneling,  decorations,  fixtures)  made  to  the
Premises or Building by Tenant or by Landlord at Tenant’s request or for Tenant’s benefit (but expressly excluding
Landlord’s  Work,  which  shall  be  restored  by  Landlord).  It  shall  be  Tenant’s  sole  responsibility  to  repair  and
restore all such items.

Notwithstanding the foregoing, (a) if there is a destruction of the Building that exceeds twenty-five percent
(25%)  of  the  replacement  value  of  the  Building  from  any  risk,  whether  or  not  the  Premises  are  damaged  or
destroyed,  or  (b)  if  Landlord  reasonably  believes  that  the  repairs  and  restoration  cannot  be  completed  despite
reasonable  efforts  within  one  hundred  fifty  (150)  days  after  the  occurrence  of  such  damage,  or  (c)  if  Landlord
reasonably believes that there shall be less than two (2) years remaining in the Term (exclusive of any extension
options) upon the substantial completion of such repairs and restoration, or (d) if any mortgagee or lender fails or
refuses  to  make  sufficient  insurance  proceeds  available  for  repairs  and  restoration,  or  (e)  if  zoning  or  other
Applicable Law or regulations do not permit such repairs and restoration, Landlord shall have the right, at its sole
option, to terminate this Lease by giving written notice of termination to Tenant within one hundred eighty (180)
days  after  the  occurrence  of  such  damage,  provided  that  Landlord  is  also  terminating  leases  of  other  tenants
similarly affected. If this Lease is terminated pursuant to the preceding sentence, all Rent payable hereunder shall
be apportioned and paid through the date of termination.

In the event that (a) Landlord fails to give written notice within sixty (60) days after receipt of the Estimate
(as defined below) of its intention to restore the Premises as provided herein, or (b) the Estimate indicates that the
Landlord’s repair work will not be completed within one hundred eighty (180) days after the date of such damage,
or (c) if any mortgagee or lender fails or refuses to make sufficient insurance proceeds available for repairs and
restoration (unless Landlord agrees

19

to  fund  the  same)  or  (d)  Landlord  fails  to  restore  the  Premises  to  the  condition  described  above  within  one
hundred twenty (120) days after the estimated completion date in the Estimate, then Tenant may elect to terminate
this Lease by written notice to Landlord to be given no later than thirty (30) days of the date last mentioned. For
purposes of this Lease, “Estimate” shall mean a written and stamped opinion from a qualified general contractor
giving a good faith estimate as to the duration of the repairs that will be needed to repair the damage as herein
contemplated.

All  time  periods  provided  in  this  Section  for  Landlord’s  performance  shall  be  subject  to  extension  on
account of reasonable delays in effectuating a satisfactory settlement with any insurance company involved and
events beyond Landlord’s reasonable control, including, without limitation, Tenant Delay (as defined in the Work
Letter) and/or (for a period not to exceed 180 days) Force Majeure. In the event of any damage or destruction to
the  Building  or  Premises,  it  shall  be  Tenant’s  responsibility  to  secure  the  Premises  and,  upon  notice  from
Landlord,  to  remove  forthwith,  at  its  sole  cost  and  expense,  property  belonging  to  Tenant  or  its  licensees  from
such portion of the Premises as Landlord shall request to the extent practicable.

20.
SUBORDINATION;  ESTOPPEL  LETTERS.  This  Lease  is  expressly  subordinate  to  any  current  or
future mortgage or mortgages placed on the Property and to all other documents executed in connection with any
such mortgage, so long as Tenant enters into a subordination, non-disturbance and attornment agreement with a
mortgagee of the Property on a commercially reasonable form. Landlord represents and warrants that, as of the
date  of  this  Lease,  Needham  Bank  (“Landlord’s  Lender”)  is  the  holder  of  a  mortgage  secured  by,  among  other
things, the Property. Tenant agrees not to pay rent more than thirty (30) days in advance of the due date and to
attorn to any party acquiring rightful possession of the Premises by or through any such mortgage. Tenant agrees
that from time to time it shall deliver to Landlord or Landlord’s mortgagee or designee within ten (10) business
days of the date of Landlord’s or Landlord’s mortgagees or such other designee’s request, a statement, in writing,
certifying  (i)  that  this  Lease  is  unmodified  and  in  full  force  and  effect,  if  this  is  so,  or  if  there  have  been
modifications, that the Lease, as modified, is in full force and effect; (ii) the dates to which Rent and other charges
have been paid; (iii) that, to Tenant’s knowledge, Landlord is not in default under any provisions of this Lease or,
if  in  default,  the  nature  thereof  in  detail;  (iv)  [intentionally  omitted]  and  (v)  such  other  factual  statements  as
Landlord or Landlord’s mortgagee or designee may require. On or prior to the execution of this Lease, Landlord
and  Tenant  shall  execute  and  deliver  to  the  other  party  the  subordination,  non-disturbance  and  attornment
agreement on a form reasonably required by Landlord’s Lender; and, thereafter, within 20 days after Landlord’s
written request, Tenant will enter into a subordination, non-disturbance and attornment agreement with any future
mortgagee  of  the  Property  on  a  commercially  reasonable  form.  Tenant’s  failure  to  execute  and  deliver  such
statements within the time required, plus an additional five business day period following a reminder notice from
Landlord, shall, at Landlord’s election, be an Event of Default and shall also be conclusive upon Tenant that (a)
this  Lease  is  in  full  force  and  effect  and  has  not  been  modified  except  as  represented  by  Landlord;  (b)  that
Landlord is not in default under any provisions of this Lease and that Tenant has no right of offset, counterclaim
or deduction against Rent other than as expressly provided in this Lease; and (c) not more than one month’s Rent
has been paid in advance.

21.

ALTERATIONS; RESTORATION.

20

(A)
Tenant  shall  not  make  or  permit  to  be  made  any  alterations,  additions,  or  improvements  in  or  to  the
Premises  (“Alterations”)  without  first  obtaining  the  prior  written  consent  of  Landlord  which  consent  may  be
withheld  in  Landlord’s  sole  discretion.  All  Alterations  (i)  must  comply  with  all  Applicable  Law,  (ii)  must  be
compatible with the Building and its mechanical, electrical, heating, ventilating, air-conditioning and life safety
systems;  (iii)  must  not  interfere  with  the  use  and  occupancy  of  any  other  portion  of  the  Building  by  any  other
tenant or their invitees; and (iv) must not affect the integrity of the structural portions of the Building. In addition,
Landlord may impose as a condition to such consent such additional, reasonable requirements as Landlord in its
reasonable  discretion  deems  necessary  or  desirable,  including,  without  limitation:  (a)  Tenant’s  submission  to
Landlord, for Landlord’s prior written approval, of all plans and specifications relating to the Alterations (to the
extent plans and specifications are typically created for such Alterations); (b) Landlord’s prior written approval of
the time or times when the Alterations are to be performed (provided that reasonable times are permitted for such
work); (c) Landlord’s prior written approval of the contractors and subcontractors performing work in connection
with  the  Alterations,  which  approval  shall  not  be  unreasonably  withheld,  conditioned  or  delayed;  (d)  Tenant’s
receipt  of  all  necessary  permits  and  approvals  from  all  governmental  authorities  having  jurisdiction  over  the
Premises prior to the construction of the Alterations; (e) Tenant’s delivery to Landlord of evidence of such bonds
or other customary assurances of performance such as subguard default insurance (with respect to work costing in
excess of $500,000) and insurance as Landlord customarily requires from such contractors or subcontractors; (f)
Tenant’s payment to Landlord of a commercially reasonable fee for Landlord’s supervision of any Alterations, not
to exceed 1% of the hard costs of constructing such Alterations or, if such Alterations costs in excess of $500,000,
a  commercially  reasonable  amount  not  to  exceed  3%  of  the  hard  costs  of  constructing  such  Alterations;  (g)
Tenant’s  and  Tenant’s  contractor’s  compliance  with  such  reasonable  construction  rules  and  regulations  and
building  standards  as  Landlord  promulgates  from  time  to  time  of  which  Tenant  has  prior  written  notice  (which
rules shall not be enforced in a discriminatory manner against Tenant), with any conflict between such rules and
regulations and this Lease being resolved in favor of this Lease; and (h) Tenant’s delivery to Landlord of “as built”
drawings of the Alterations in such form or medium as Landlord may reasonably require (provided that no such
“as  built”  plans  shall  be  required  if  the  Alterations  were  not  subject  to  plans  and  specifications).  All  direct  and
indirect costs relating to any modifications, alterations or improvements of the Building, whether outside or inside
of the Premises, required by any governmental agency or by Applicable Law as a condition or as the result of any
Alteration requested or effected by Tenant shall be borne by Tenant. Tenant shall not permit any mechanic’s lien
or other liens to be placed upon the Premises or the Building as a result of any materials, services or labor ordered
by  or  provided  to  Tenant  or  any  of  Tenant’s  agents,  officers,  or  employees  (other  than  inchoate  liens).  Without
waiving any other rights or remedies under this Lease, Landlord may bond or insure or otherwise discharge any
such  lien  not  discharged  or  bonded  over  within  15  days  after  the  same  has  been  placed  on  the  Premises  or
Property (the parties acknowledging that a notice of contract is not a lien for the purposes of this sentence) and
Tenant  shall  reimburse  Landlord  for  any  amount  paid  by  Landlord  in  connection  therewith  as  Additional  Rent
upon demand. Subject to Landlord’s reasonable approval of the plans therefor, Tenant may utilize glass treatments
on  the  interior  windows  and  doors  of  the  Premises  if  reasonably  necessary  to  protect  the  privacy  of  activities
within  the  Premises  (to  the  extent  the  same  would  otherwise  be  visible  from  the  street  level  adjacent  to  the
Building) and install its own security system within the Premises. Landlord

21

acknowledges that frosted glass on the interior windows and doors within the Premises is a reasonable window
treatment for purpose so the immediately preceding sentence.

(B)
Upon  the  expiration  or  earlier  termination  of  the  Lease,  Tenant  shall  surrender  the  Premises  in  the
condition in which it was delivered to Tenant, reasonable wear and tear and damage by casualty or condemnation
excepted. Tenant shall remove any and all Alterations, trade fixtures, equipment, data/telecommunications cabling
and  wiring  installed  by  or  on  behalf  of  Tenant  (to  the  extent  not  connected  at  both  ends  or  cut  and  capped  at
interior walls in compliance with applicable codes) and furniture from the Premises and Tenant shall fully restore
and repair any damage, including any structural damage, occasioned by the removal of the same. Notwithstanding
the foregoing, Landlord may require, by notice given at least 90 days prior to Lease expiration, that Tenant not
remove any or all Alterations and any such Alteration or Alterations shall become a part of the Building and shall
belong to Landlord without compensation, and title thereto shall pass to Landlord under this Lease as by a bill of
sale.  At  Landlord’s  election,  all  Alterations,  trade  fixtures,  equipment,  wire  and  cable,  furniture,  fixtures,  other
personal  property  not  removed  shall  conclusively  be  deemed  to  have  been  abandoned  by  Tenant  and  may  be
appropriated, sold, stored, destroyed or otherwise disposed of by Landlord without notice to Tenant or to any other
person and without obligation to account for them. Tenant shall pay Landlord all reasonable expenses incurred in
connection  with  Landlord’s  disposition  of  such  property,  including  without  limitation  the  cost  of  repairing  any
damage  to  the  Building  or  the  Premises  caused  by  removal  of  such  property,  and  shall  hold  Landlord  harmless
from loss, liability, or expense arising from the claims of third parties such as Tenant’s lenders whose loans are
secured by such property. Tenant’s obligations under this Section shall survive the end of this Lease.

Notwithstanding the foregoing or anything to the contrary contained herein, Landlord’s consent shall not
be  required  for  interior  non-structural  alterations  or  improvements  to  the  Premises,  including  without  limitation
the installation, repair, replacement and relocation from time to time of Tenant’s personal property, trade fixtures,
equipment  and  furnishings  (to  the  extent  the  foregoing  constitute  alterations);  provided  such  interior  non-
structural alterations or improvements cost less than $10.00 per square foot of the Premises per alteration.

22.

DEFAULT; REMEDIES.

(A)
In  addition  to  any  other  acts  or  omissions  designated  in  this  Lease  as  Events  of  Default,  each  of  the
following shall constitute an Event of Default by Tenant hereunder: (i) the failure to make any payment of Rent or
any installment thereof or to pay any other sum required to be paid by Tenant under this Lease or under the terms
of any other agreement between Landlord and Tenant within five (5) days after notice that such amount is past due
(provided that no such notice shall be required more than one time in any 12 month period for any payments of
Base  Rent  or  Additional  Rent  on  account  of  Operating  Expenses  or  Taxes);  (ii)  the  use  or  occupancy  of  the
Premises for any purpose other than the Permitted Use without Landlord’s prior written consent or the conduct of
any activity in the Premises which constitutes a violation of Applicable Law; (iii) if the interest of Tenant or any
part thereof under this Lease shall be levied on under execution or other legal process and said interest shall not
have been cleared by said levy or execution within thirty (30) days from the date thereof; (iv) if any voluntary
petition in bankruptcy or for corporate

22

reorganization or any similar relief shall be filed by Tenant or any guarantor of the Lease, or if any involuntary
petition  in  bankruptcy  or  for  corporate  reorganization  or  any  similar  relief  shall  be  filed  against  Tenant  or  any
guarantor of the Lease or if a receiver shall be appointed for Tenant or any guarantor or any of the property of
Tenant or guarantor and in any event is not discharged or dismissed within sixty (60) days thereafter; (v) if Tenant
or  any  guarantor  of  the  Lease  shall  make  an  assignment  for  the  benefit  of  creditors  or  if  Tenant  shall  admit  in
writing  its  inability  to  meet  Tenant’s  debts  as  they  mature;  (vi)  if  any  insurance  required  to  be  maintained  by
Tenant pursuant to this Lease shall be cancelled or terminated or shall expire or shall be reduced or materially and
adversely changed, except, in each case, as permitted in this Lease, or mutually agreed to in writing by the parties;
(vii)  if  Tenant  shall  fail  to  discharge  or  bond  over  any  lien  placed  upon  the  Premises  in  violation  of  this  Lease
within  20  days  after  the  same  has  been  placed  upon  the  Premises;  (viii)  if  any  Security  Deposit  required  to  be
maintained by Tenant pursuant to this Lease shall be cancelled or terminated or shall expire or shall be reduced or
materially  changed,  except,  in  each  case,  as  permitted  in  this  Lease,  or  mutually  agreed  to  in  writing  by  the
parties; (ix) if Tenant shall abandon or vacate the Premises during the Term; (x) if Tenant shall fail to execute and
deliver an estoppel certificate or subordination agreement as and when required hereunder; or (xi) the failure to
observe or perform any of the other covenants or conditions in this Lease which Tenant is required to observe and
perform and which Tenant has not corrected within thirty (30) days after written notice thereof to Tenant; or if said
failure reasonably requires a longer period to cure, then provided Tenant promptly commences and diligently and
continuously  pursues  such  cure  Tenant  shall  have  such  additional  time  as  is  necessary  for  the  purposes  of
consummating such curative action not to exceed ninety (90) consecutive days in the aggregate.

(B)
Upon the occurrence of an Event of Default by Tenant, Landlord may, at its option, with or without notice
or demand of any kind to Tenant or any other person (except as expressly required herein or by applicable law),
exercise  any  one  or  more  of  the  following  described  remedies,  in  addition  to  all  other  rights  and  remedies
provided at law, in equity or elsewhere herein, and such rights and remedies shall be cumulative and none shall
exclude any other right allowed by Applicable Law:

(i)
Landlord may terminate this Lease, repossess and re-let the Premises, in which case Landlord shall
be  entitled  to  recover  as  damages  (in  addition  to  any  other  sums  or  damages  for  which  Tenant  may  be
liable to Landlord for the period prior to such election) a lump sum equal to the greater of (A) an amount
equal to the total Rent that would have been payable during the twelve (12) month period (or lesser period
then remaining in the term) immediately following the termination of this Lease if this Lease had not been
terminated  as  a  result  of  an  Event  of  Default,  or  (B)  the  amount  (if  any)  by  which  the  aggregate  of  the
unpaid Rent and all other sums payable under this Lease for the balance of the Term (as if the Lease had
not been terminated and assuming Operating Expenses and Taxes increased three (3%) percent per year)
exceeds the amount of such rental loss, if any, as Tenant affirmatively proves could be reasonably avoided,
with such difference being discounted to present value at the federal funds rate (but in no event less than
zero  percent)  Should  the  fair  market  rental  value  of  the  Premises  for  the  balance  of  the  Term  (after
deduction of all anticipated expenses of reletting) exceed the value of the Rent to be paid by Tenant for the
balance of the Term, Landlord shall have no obligation to pay to or otherwise credit Tenant

23

for any such excess amount. Landlord and Tenant specifically acknowledge and agree that accelerating the
Rent  as  liquidated  damages  is  fair  and  reasonable  because,  among  other  reasons,  each  of  the  foregoing
defaults is significant and material and the parties cannot foresee when in the Term any such default may
occur, what the commercial rental market for the Premises may be at the time of such default, what the
cost  of  finding  a  substitute  tenant  may  be  at  such  time,  or  how  long  the  premises  may  remain  vacant
following any such default

(ii)
Landlord may, without terminating the Lease, terminate Tenant’s right of possession, repossess the
Premises  including,  without  limitation,  removing  all  or  any  part  of  Tenant’s  personal  property  in  the
Premises (after notice to Tenant) and to place such personal property in storage or a public warehouse at
the expense and risk of Tenant, and relet the same for the account of Tenant for such rent and upon such
terms  as  shall  be  satisfactory  to  Landlord.  For  the  purpose  of  such  reletting,  Landlord  is  authorized  to
decorate, repair, remodel or alter the Premises. Tenant shall pay to Landlord as damages a sum equal to all
Rent under this Lease for the balance of the Term unless and until the Premises are relet. If the Premises
are relet, Tenant shall be responsible for payment upon demand to Landlord of any deficiency between the
Rent  as  relet  and  the  Rent  for  the  balance  of  this  Lease,  all  costs  and  expenses  of  reletting,  and  all
reasonable  decoration,  repairs,  remodeling,  alterations,  additions  and  collection  of  the  Rent  accruing
therefrom  to  the  extent  allocable  to  the  remainder  of  the  Term.  Tenant  shall  not  be  entitled  to  any  rents
received by Landlord in excess of the Rent provided for in this Lease. No re-entry or taking possession of
the Premises by Landlord shall be construed as an election to terminate this Lease unless a written notice
of such intention is given to Tenant or unless the termination thereof is decreed by a court of competent
jurisdiction.  Notwithstanding  any  reletting  without  termination,  as  set  forth  in  Section  22(b)(ii)  above,
Landlord  may  at  any  time  thereafter  elect  to  terminate  this  Lease  for  any  breach,  and  in  addition  to  the
other  remedies  it  may  have,  recover  as  damages  (in  addition  to  any  other  sums  or  damages  for  which
Tenant  may  be  liable  to  Landlord)  a  lump  sum  equal  to  the  amount  by  which  the  present  value  of  the
excess  Rent  remaining  to  be  paid  by  Tenant  for  the  balance  of  the  Term  of  the  Lease  exceeds  the  fair
market rental value of the Premises, after deduction of all anticipated expenses of reletting. In the event
Landlord repossesses the Premises as provided above, Landlord may (with prior notice to Tenant) remove
all  persons  and  property  from  the  Premises  and  store  any  such  property  at  the  cost  of  Tenant,  without
liability for damage; and

(iii)
Landlord  may,  but  shall  not  be  obligated  to,  and  without  waiving  or  releasing  Tenant  from  any
obligations of Tenant hereunder, make any payment or perform such other act on Tenant’s part to be made

from time to time and that no suit or recovery of any portion due Landlord hereunder shall be any defense to any
subsequent action brought for any amount not theretofore reduced to judgment in favor of Landlord (except to the
extent the same would result in double recovery of any such amounts by Landlord).

Tenant shall promptly pay upon notice, as Additional Rent, all reasonable out of pocket costs, charges and
(E)

remedy  on  account  of  the  violation  of  such  provision,  even  if  such  violation  be  continued  or  repeated
subsequently,  and  no  express  waiver  by  either  party  shall  be  valid  unless  in  writing  and  shall  not  affect  any
provision  other  than  the  one  specified  in  such  written  waiver  and  that  provision  only  for  the  time  and  in  the
manner specifically stated in the waiver. No receipt of monies by Landlord from Tenant after the termination of
this  Lease  shall  in  any  way  alter  the  length  of  the  Term  or  Tenant’s  right  of  possession  hereunder  or  after  the

receipt of such monies, it being agreed that after the service of notice or the commencement of a suit or after final
judgment for possession of the Premises, Landlord may receive and collect any Rent due, and the payment of Rent
shall  not  waive  or  affect  said  notice,  suit  or  judgment.  Landlord  shall  not  be  required  to  serve  Tenant  with  any
notices or demands as a prerequisite to its exercise of any of its rights or remedies under this Lease, other than
those notices and demands specifically required under this Lease or applicable law.

been  rendered  impractical,  in  Landlord’s  sole  judgment,  for  the  operation  of  Landlord’s  rental  activities  on  the
Property, this Lease shall terminate on the date of the taking or conveyance, and rent shall be apportioned to the
date thereof, provided that Landlord is also terminating the leases of any other tenants similarly affected. Tenant
shall  have  no  right  to  any  apportionment  of  or  any  share  in  any  condemnation  award  or  judgment  for  damages
made for the taking or conveyance of any part of the Premises or the Building (nothing herein prohibiting Tenant
from making a separate claim for its loss of personal property and moving or relocation expenses, if any). If any
portion of the Premises, all reasonable access thereto, or such portions of the Building or Property are taken such

RIGHT OF FIRST OFFER TO LEASE ADDITIONAL SPACE.

(A)
Provided that (i) no Event of Default then exists and no condition exists which, with the giving of notice or
passage of time or both, would constitute an Event of Default hereunder, (ii) this Lease is then in full force and
effect, (iii) the Tenant named herein has not (x) assigned this Lease other than pursuant to a Permitted Transfer, or
(y) sublet of more than 25% of the Premises under then-effective sublease(s), if, at any time during the Term, all
or any portion of that certain space that is located on the first (1st) floor of the Building and then contiguous to the
Premises (“ROFO Space”) is or will be “available for lease” and Landlord desires to lease such space, Landlord
shall notify Tenant. Landlord’s notice shall identify the space available (the “Offered Space”), set forth the terms
and conditions on which it is willing to lease the Offered Space including the rental rate (the “Proposed Rent”),
the term (which may not be coterminous with the Term applicable to the Premises), and the date on which such
Offered Space is expected to be available (collectively, the “Terms”). Tenant shall thereupon have the right and
option to lease the

29

Offered  Space  on  the  Terms  by  delivering  notice  to  Landlord  within  ten  (10)  business  days  after  receipt  of
Landlord’s notice, time being of the essence. If Tenant elects to lease the Offered Space, it shall, within twenty
(20) days after such election, enter into an amendment to this Lease on a form prepared by Landlord incorporating
the Offered Space as part of the Premises subject to the Terms and the other terms and conditions of this Lease.

If Tenant shall not elect to lease the Offered Space within such 10-business day period, or fails to enter
(B)
into such an amendment to this Lease within such 20-day period (provided that such amendment is consistent with
the terms of this Section), then Tenant shall have no further rights under this Section with respect to the Offered
Space  until  and  unless  (1)  Landlord  enters  into  a  lease  for  such  space  and  thereafter  such  space  once  again
becomes available for lease, or (2) Landlord has failed to enter into a lease for the Offered Space within nine (9)
months following the date of the ROFO Notice, then in either case, Landlord shall once again offer such space to
Tenant pursuant to the terms of this Section 30.

Space  shall  not  be  deemed  to  be  “available  for  lease”  if  such  space  is  the  subject  of  any  option  or
(C)
commitment  now  held  by  another  tenant  as  further  set  forth  on  Exhibit  F  or  the  renewal  or  extension  of  an
expiring lease with a then existing tenant. Landlord shall not be liable for any damages for any holdover tenant or
other  occupant  of  any  Offered  Space.  If  for  any  reason  Landlord  is  unable  to  deliver  possession  of  the  Offered
Space due to a holdover tenant or other occupant in the Offered Space, Landlord shall not be liable to Tenant for
any  resultant  loss  or  damage  and  this  Lease  shall  not  be  affected  in  any  way,  except  that  Tenant  shall  have  the
right to rescind its exercise of its right to lease such Offered Space.

Notwithstanding anything to the contrary contained herein, Tenant’s right of first offer to lease the ROFO

(D)
Space shall be subject to the rights of any other tenant(s) of the Property held by another tenant as of the date
hereof, as further set forth on Exhibit F; and, nothing provided herein shall be deemed to grant Tenant a superior
right to lease the ROFO Space over any existing tenant(s) of the Property as of the date of this Lease that is
identified on Exhibit F.

Landlord shall not be obligated to enforce parking limits. Tenant shall not use any parking space designated by
Landlord as visitor parking (other than by Tenant’s visitors) or as exclusive to other parties. If Tenant uses parking
in excess of that provided for herein, and if such excess use occurs

32

on a regular basis, and if Tenant fails, after written notice from Landlord of any one violation, to reduce its excess
use of the parking areas, then such excess use shall constitute an Event of Default if not cured within applicable
notice and cure periods.

Notwithstanding  the  foregoing  or  anything  to  the  contrary  in  this  Lease,  Landlord  may  temporarily  relocate
parking  for  tenants  in  the  Building,  including  Tenant,  to  another  location  off  the  Property  (within  a  reasonable
distance  from  the  Premises,  unless  a  shuttle  or  valet  service  is  provided  by  Landlord  at  Landlord’s  cost)  in
connection  with  the  development  of  an  additional  building  or  parking  structure  on  the  Property,  provided  that
Landlord provides Tenant with other parking at Landlord’s sole cost and expense, and, in connection with such
temporary  relocation,  Tenant  hereby  acknowledges  and  agrees  that  the  minimum  parking  space  required  to  be
furnished to Tenant on the Property that are set forth above shall not be required to be maintained by Landlord on
the Property during the construction of such structure on the Property. Any such temporary relocation shall not
exceed five hundred and fifteen (515) days in duration.

33.
SIGNAGE. Subject to Landlord’s review and approval, Tenant, at Landlord’s expense, shall be entitled to
Building  standard  suite  entry  and  directory  signage.  Landlord  may  specify  that  the  design  of  such  signage  be
similar  to,  or  consistent  with,  the  design  and  location  of  other  signs  identifying  tenants  in  the  Building.  Tenant
may use its corporate logo on any signage. Such signage shall be subject to all Applicable Law and ordinances.

34.
SUBSTITUTION OF PREMISES. At any time after the date of execution of this Lease, Landlord may,
but  on  no  more  than  one  occasion  during  the  Term,  substitute  other  premises  in  the  Building  for  the  Premises
(“Substitute  Premises”),  in  which  event  the  Substitute  Premises  shall  be  deemed  to  be  the  Premises  for  all
purposes under this Lease upon delivery of the same to Tenant in the condition required by this Lease; provided,
however, that: (i) the Substitute Premises shall be located in the Building, in contiguous space on a single floor,
shall be no less than the Premises in square footage, and at least equivalent in appropriateness for the Permitted
Use,  with  tenant  improvements  that  are  constructed  at  Landlord’s  sole  cost  and  expense  to  replicate  the  tenant
improvements  existing  (or  required  to  be  existing  pursuant  to  this  Lease)  in  the  Premises  in  accordance  with  a
mutually agreeable plan; (ii) Landlord shall pay the reasonable expense of, and arrange for, the moving Tenant, its
property and equipment to the Substitute Premises in a manner reasonably acceptable to Tenant; (iii) there is no
material interruption in Tenant’s business as a result of such relocation (e.g., any move occurs outside of Tenant’s
normal business hours in the Premises, such as over a weekend), and (iv) Landlord shall give to Tenant not less
than 180 days’ prior written notice of such substitution. In no event shall tenant have any obligation to pay more
in Base Rent or Additional Rent on account of any Substitute Premises. Following any such notice of Landlord’s
intent to relocate the Premises in accordance with this Section 34, Landlord and Tenant shall enter into a mutually
agreeable  amendment  to  this  Lease  memorializing  the  same.  If  the  substitution  occurs  in  accordance  with  the
terms  and  conditions  of  this  Section  34  prior  to  the  occurrence  of  the  Commencement  Date,  Tenant  shall  be
entitled  to  an  increase  in  the  Landlord’s  Work  Cost  Cap  in  an  amount  equal  to  $60  per  square  foot  of  any
additional rentable square feet within the substituted Premises, and in no event shall any Tenant Delay be deemed
to occur on account of such substitution or the need to revise Tenant’s Site Plan to reflect the substituted Premises.

35.
CERTAIN  RIGHTS  RESERVED  TO  LANDLORD.  Landlord  reserves  the  following  rights,  each  of
which  Landlord  may  exercise  without  notice  or  liability  to  Tenant,  and  the  exercise  of  any  such  rights  in
compliance  with  this  Lease  shall  not  be  deemed  to  constitute  an  eviction  or  disturbance  of  Tenant’s  use  or
possession of the Premises and shall not give rise to any claim for set-off or abatement of Rent or any other claim:
(a)  to  enter  the  Premises  upon  reasonable  prior  notice  to  Tenant  subject  to  this  Section  35  for  the  purposes  of
examining  the  same  or  to  make  repairs  or  alterations  or  to  provide  any  service;  (b)  to  change  the  arrangement
and/or  locations  of  entrances,  or  passageways,  doors  and  doorways,  and  corridors,  windows,  elevators,  stairs,
parking  areas  and  any  other  common  areas,  other  than  with  respect  to  the  Premises,  (c)  to  change  the  name  or
street address of the Building or the suite number of the Premises on at least 30 days’ prior notice to Tenant; (d) to
install,  affix  and  maintain  any  and  all  signs  on  the  exterior  or  interior  of  the  Building;  (e)  to  make  repairs,
decorations, alterations, additions or improvements, whether structural or otherwise, in, about and to the Building
or common areas and for such purposes temporarily close doors, corridors and other areas of the Building and to
temporarily interrupt or temporarily suspend services or use of common areas in connection with the same; (f) to
retain at all times, and to use in appropriate instances, keys to all doors within and into the Premises; subject to
this Section 35; (g) to grant to any person or to reserve unto itself the exclusive right to conduct any business or
render  any  service  in  the  Building  (other  than  in  a  manner  that  materially  adversely  affects  Tenant’s  right  to
occupy the Premises); (h) to show the Premises at reasonable times within the final 12 months of the Term; (i) to
install,  use  and  maintain  in  and  through  the  Premises  pipes,  conduits,  wires  and  ducts  serving  the  Building
provided the same are installed behind walls, above ceilings, and below floors (or, to the extent that ceilings of the
Premises are exposed on the Commencement Date, within the customary space beneath an exposed ceiling that is
used for Building mechanical equipment in similar first class office space); (j) to reasonably approve the weight,
size and location of safes or other heavy equipment or other articles which may be located in the Premises and to
reasonably determine the time and manner in which such articles may be moved in, about or out of the Building or
Premises;  and  (k)  to  take  any  other  action  which  Landlord  deems  reasonable  in  connection  with  the  operation,
maintenance, repair, replacement, marketing or preservation of the Premises or Building. Landlord shall conduct
any of its activities under this Section 35 in a manner consistent with similar office buildings in the Lexington,
Massachusetts area and in a manner that does not unreasonably interfere with Tenant’s use and occupancy of the
Premises, access thereto, or otherwise result in a breach of this Lease. Tenant shall have a right to accompany any
such  access  other  than  in  the  event  of  an  emergency  threatening  life  or  property.  Landlord  acknowledges  that
Tenant may designate limited areas of the Premises as “secure areas” where confidential information may be kept
by  Tenant,  and  Landlord’s  access  to  such  areas  shall  require  Tenant  to  accompany  Landlord  at  all  times  in
connection with such entry (other than in the event of an emergency threatening life or property). The reduction or
elimination  of  Tenant’s  light,  air  or  view  by  (i)  the  construction  of  additional  buildings  at  a  distance  from  the
Building that is greater than the setback requirement established by the Town of Lexington and other applicable
laws  (without  the  application  of  any  zoning  or  other  relief),  (ii)  the  construction  of  electrical  transformers,
generator equipment, or other similar equipment and fixtures in a manner consistent with similar office complexes
in suburban office parks located in the Greater Boston area, or (iii) the temporary repair and maintenance of the
exterior  windows  or  façade  of  the  Building  for  reasonable  periods,  shall  not  affect  Tenant’s  liability  under  this
Lease, nor shall it create any liability of Landlord to Tenant.

Tenant  shall  enter  into  a  commencement  letter  agreement  (the  “Commencement  Letter”)  in  form  substantially
similar  to  that  attached  hereto  as  Exhibit  D  within  15  days  after  Landlord’s  delivery  of  the  same  to  Tenant,
provided  that  failure  to  enter  into  any  such  agreement  shall  not  be  deemed  to  modify  or  amend  the
Commencement Date under this Lease or Tenant’s obligation to pay rent when due.

37. WAIVER OF RIGHT TO JURY TRIAL. LANDLORD AND TENANT WAIVE THEIR RESPECTIVE
RIGHTS  TO  A  TRIAL  BY  JURY  OF  ANY  CLAIM,  ACTION,  PROCEEDING  OR  COUNTERCLAIM  BY
EITHER  PARTY  AGAINST  THE  OTHER  ON  ANY  MATTERS  ARISING  OUT  OF  OR  IN  ANY  WAY

ADDITIONAL STIPULATIONS

These  additional  stipulations  are  a  part  of  the  Lease  dated  January  14,  2022  by  and  between  NRL  91
HARTWELL LLC, a Delaware limited liability company and UNIQURE, INC., a Delaware corporation for the
Premises located as 91 Hartwell Avenue, Lexington, MA 02421.

EXTENSION OPTION. So long as there exists no default either at the time of exercise or on the first day of the
Extension Term (as hereinafter defined) and Tenant has not assigned this Lease in whole or in part other than to a
Permitted Transferee nor are sublets of more than 25% of the Premises in effect as of the commencement of the
Extension Term, Tenant shall have the option to extend the Term for one (1) additional five (5) year period (the
“Extension Term”) upon written notice to Landlord given not less than nine (9) months and not more than twelve
(12) months prior to the expiration of the Term. If Tenant fails to exercise its option to extend the Term strictly
within the time period set forth in this section, then Tenant’s option to extend the Term shall automatically lapse
and be of no further force or effect. In the event that Tenant exercises the option granted hereunder, the Extension
Term  shall  be  upon  the  same  terms  and  conditions  as  are  in  effect  under  this  Lease  immediately  preceding  the
commencement  of  such  Extension  Term  except  that  the  Base  Rent  due  from  the  Tenant  shall  be  modified  as
provided  herein,  and  Tenant  shall  have  no  further  right  or  option  to  extend  the  Term  or  to  any  additional
abatements,  improvement  allowance  or  other  inducements  on  account  of  the  Extension  Term.  If  Tenant  timely
exercises  its  option  to  extend  the  Term,  then  no  later  than  thirty  (30)  days  following  receipt  of  Tenant’s  notice,
Landlord shall notify Tenant in writing of Landlord’s determination of the Fair Market Rent (as defined below) for
the  Extension  Term  (“Landlord’s  Rental  Notice”).  If  Tenant  does  not  object  to  Landlord’s  determination  of  the
Fair Market Rent by written notice to Landlord within fifteen (15) days after the date of Landlord’s Rental Notice,
then  Tenant  shall  be  deemed  to  have  accepted  the  Fair  Market  Rent  set  forth  in  Landlord’s  Rental  Notice.  If
Tenant  does  timely  object  to  Landlord’s  determination  of  Fair  Market  Rent  for  the  Extension  Term,  the  parties
shall use commercially reasonable efforts to agree upon the Fair Market Rent for the Extension Term, provided,
however,  if  the  parties  cannot  agree  upon  the  Fair  Market  Rent  within  thirty  (30)  days  after  Landlord  receives
Tenant’s notice of objection, then the determination of Fair Market Rent shall be submitted to arbitration as further
provided below.

If Tenant timely objects to Landlord’s Rental Notice, and the parties cannot agree on Base Rent for the Extension
Term  within  thirty  (30)  days  after  Landlord  receives  Tenant’s  notice  of  objection,  then  the  Term  shall
automatically be extended and Base Rent for the Extension Term shall be submitted to arbitration as follows: Base
Rent  shall  be  determined  by  impartial  arbitrators  (who  shall  be  qualified  brokers  with  at  least  ten  (10)  years  of
experience dealing with like types of properties in the market area), one to be chosen by the Landlord, one to be
chosen by Tenant, and a third to be selected, if necessary, as below provided, and shall reflect the greater of (i) the
rate that would be agreed upon in an arms’ length negotiation between a landlord and a tenant on or about the date
on which the Extension Term is to begin for a comparable term and for space comparable to the Premises in the
Building and buildings comparable to the Building in the market

Exhibit B - 1

area,  taking  into  account  all  reasonable  factors  considered  in  the  determination  of  such  fixed  monthly  rent,
including,  without  limitation,  any  material  economic  differences  between  the  terms  of  this  Lease  and  any
comparison  lease,  such  as  the  manner,  if  any,  in  which  the  landlord  under  any  such  lease  is  reimbursed  for
operating  expenses  and  taxes  and  (ii)  the  Base  Rent  payable  during  the  last  month  of  the  current  Term  (as
applicable, the “Fair Market Rent”). The unanimous written decision of the two first chosen (without selection and
participation of a third arbitrator), or otherwise the written decision of a majority of three arbitrators chosen and
selected as aforesaid, shall be conclusive and binding upon Landlord and Tenant. Landlord and Tenant shall each
notify the other of its chosen arbitrator within ten (10) days following the call for arbitration and, unless such two
arbitrators shall have reached a unanimous decision within thirty (30) days after their designation, they shall select
an impartial third arbitrator to determine the market value as herein defined. Such third arbitrator and the first two
chosen shall render their decision within thirty (30) days following the date of appointment of the third arbitrator
and shall notify Landlord and Tenant thereof, which decision shall be final and binding on the parties. Landlord
and Tenant shall each pay the expenses of its own arbitrator and shall share the payment of expenses of the third
arbitrator equally, regardless of the outcome of arbitration. If the dispute between the parties as to the Base Rent
for the Extension Term has not been resolved before the commencement of the Extension Term, Tenant shall pay
Base Rent for the Extension Term at the last Base Rent applicable under the Lease until either (i) agreement of the
parties as to the Fair Market Rent, or (ii) decision of the arbitrators, as the case may be, at which time Tenant shall
promptly pay any underpayment of Base Rent to Landlord, or Landlord shall credit the overpayment of Base Rent
against the next installment of rental or other charges due to Landlord.

WORK LETTER

1.

Landlord’s  Work.  Landlord  will  make  certain  improvements  to  the  Premises  (the  “Landlord’s
Work”) as set forth on that certain design and space plan and scope of work (collectively, the “Site Plan”), which
Site Plan shall be prepared by or for Tenant no later than February 15, 2022, and shall provide for a scope of
work that can be completed by the Estimated Commencement Date as reasonably estimated by Landlord upon the
advice of the General Contractor (as defined below) unless Tenant agrees in writing that any time estimated by the
General Contractor beyond the Estimated Commencement Date shall be treated as Tenant Delay. Such Site Plan
shall be subject to the prior written approval of Landlord and Tenant after the date hereof. Following the date of
this  Lease,  and  Tenant’s  initially  approved  Site  Plan,  Landlord  shall  further  develop  the  Site  Plan  in  a  manner
consistent with the initial Site Plan to permit the Landlord to obtain a building permit and construct the Landlord’s
Work  in  accordance  with  the  project  design  and  construction  milestones  referenced  on  Schedule  1,  attached.
Landlord has retained H&H Builders as the general contractor for the Landlord’s Work (the “General Contractor”)
and  Dimella  Shaffer  as  the  architect  for  the  Landlord’s  Work  (the  “Architect”).  With  respect  to  the  Site  Plan
design  phases  set  forth  on  Schedule  2,  attached,  Tenant  shall  have  five  (5)  business  days  from  Landlord’s
submission of such design phases to Tenant to approve or disapprove the same. Tenant’s failure to so approve or
disapprove  within  such  five  (5)  business  day  period  shall  constitute  a  Tenant  Delay  (as  defined  herein)  and,  at
Landlord’s election, be deemed Tenant’s approval thereof. Tenant’s disapproval of such plans and specifications
shall specifically identify the nature of such disapproval. Landlord shall then have such plans and specifications
amended to incorporate those items specified in Tenant’s disapproval to which Landlord agrees. Landlord’s and
Tenant’s  approval  of  such  plans  and  specifications  shall  not  be  unreasonably  withheld,  conditioned  or  delayed.
Landlord and Tenant shall diligently work together in good faith to agree upon such plans and specifications, it
being agreed that Tenant shall have no right to request that such plans and specifications be revised to reflect any
work which is not contemplated on Schedule 1 attached hereto or reasonably inferable therefrom except pursuant
to Section 4 below. Upon approval, or deemed approval, of such additional plans and specifications the same shall
be deemed the “Site Plan” for the purposes of this Work Letter. Except as may be otherwise shown on the Site
Plans, Landlord shall perform Landlord’s Work using building standard materials, quantities and procedures then
in use by Landlord, all in a manner consistent with similar office buildings in the Lexington, Massachusetts area.

Notwithstanding  the  foregoing  or  anything  to  the  contrary  contained  herein,  Landlord  shall  only  be
required  to  pay  for,  and  be  responsible  for  the  cost  of,  Landlord’s  Work  up  to  an  amount  not  to  exceed  Seven
Hundred Sixty-Two Thousand Nine Hundred Sixty Dollars ($762,960.00) (the “Landlord Work Cost Cap”), which
Landlord  Work  Cost  Cap  shall  include,  without  limitation,  architectural  and  engineering  costs.  In  the  event  the
Cost  (as  defined  below)  of  Landlord’s  Work  exceeds  the  Landlord  Work  Cost  Cap,  then  Tenant  shall  pay  such
excess (the “Excess Costs”) to Landlord as Additional Rent within thirty (30) days of each invoice from Landlord
therefor (such

Exhibit E - 1

invoices to be issued no more than once each month as such work progresses, together with reasonable back-up
evidencing such Costs).

Until Landlord has incurred Costs in an amount equal to the Landlord Work Cost Cap, in connection with
any  payments  to  Landlord’s  contractors  in  connection  with  the  Landlord’s  Work,  each  of  Landlord  and  Tenant
shall fund its respective pro rata share of such payment based on the ratio of the Excess Cost to the Estimate (as
defined  below).  By  way  of  example  and  for  illustration  purposes  only,  if  the  total  Costs  in  the  Estimate  were
$10.50 psf, the Landlord Work Cost Cap $7 psf, and the Excess Costs were $3.50 psf, Tenant and Landlord would
be required to fund one-third and two-thirds, respectively, of each interim and final payment.

“Costs”  means  the  actual  out  of  pocket  costs  incurred  by  Landlord  in  the  permitting,  design  and
construction of the Landlord’s Work, with the categories of Costs to be as shown on the preliminary non-binding
budget  (which  budget  is  based  on  Landlord’s  consultation  with  the  General  Contractor  and  Architect;  Tenant
acknowledging  that  the  Landlord  is  not  guarantying  any  amounts  set  forth  in  the  budget)  (the  “Estimate”).  The
form  of  Estimate  is  attached  as  Schedule  3.  In  no  event  shall  Costs  include  any  payments  to  Landlord  or  its
affiliates (other than the construction management fee referenced below), amounts incurred to repair defective or
non-conforming work, Costs incurred for, or allocable to, work that is not Landlord’s Work, and finance charges
or interest, or costs not permitted under the construction contract (which shall be subject to Tenant’s reasonable
review and approval).

Tenant  shall  also  pay  Landlord  a  construction  management  fee  on  account  of  its  supervision  and
coordination of Landlord’s Work in an amount equal to five percent (5%) of the total Costs of such Landlord’s
Work  that  has  been  incurred  by  Landlord,  which  construction  management  fee  shall  be  paid  by  Tenant,  as
Additional Rent, on a monthly basis as such costs and expenses related to Landlord’s Work are actually incurred
by Landlord, prorated over the duration of the Landlord’s Work.

2.

Substantial  Completion.  “Substantial  Completion”  or  “Substantially  Complete”  means  that
Landlord’s  Work  has  been  sufficiently  completed  such  that  the  Premises  is  suitable  for  its  intended  purpose
without  unreasonable  interference  on  account  of  the  completion  of  the  remainder  of  the  Landlord’s  Work,
notwithstanding  any  minor  or  insubstantial  details  of  construction,  decoration  or  mechanical  adjustment  that
remain to be performed (“Punch List Items”); provided that Landlord has delivered the Premises to Tenant free of
occupants and personal property, and broom clean in compliance with Legal Requirements, and with all Building
systems serving the same in good working order in all material respects. The Landlord shall give Tenant at least
two (2) Business Days’ prior written notice of the date of Substantial Completion, following which date Landlord
and Tenant shall walk through the Premises with the Architect to identify the Punch List Items, if any. Landlord
shall promptly thereafter request the Architect to promptly deliver a list of the Punch List Items to Landlord and
Tenant for their confirmation. Landlord shall complete all Punch List Items within 30 days following the date of
Substantial Completion (or such longer period as is reasonably required, but in any event not more than 60 days);
and, to the extent Tenant shall have given Landlord notice of any subsequently discovered

Exhibit E - 2

latent defects in the Landlord’s Work not reasonably identifiable during the aforementioned walk-through not later
than 350 days after the Commencement Date, Landlord shall cause the General Contractor to repair the same at no
cost  or  expense  to  Tenant.  To  the  extent  that  Tenant  fails  to  timely  notify  Landlord  of  any  such  latent  defects,
Tenant shall be deemed conclusively to have approved the completion of Landlord’s Work and Tenant shall have
no claim that Landlord has failed to perform any of Landlord’s Work required under this Work Letter. Landlord
will  use  commercially  reasonable  efforts  to  Substantially  Complete  Landlord’s  Work  on  or  before  one  (1)  year
after Landlord’s written approval of the initial Site Plan (as defined in the Work Letter) in accordance with this
Work  Letter.  If  there  is  a  delay  in  the  Substantial  Completion  of  the  Landlord’s  Work  for  any  reason  neither
Landlord,  nor  the  managing  or  leasing  agent  of  the  Building,  nor  any  of  their  respective  agents,  partners  or
employees, shall have any liability to Tenant in connection with such delay, nor shall the Lease be affected in any
way except as expressly provided in the Lease. Notwithstanding the foregoing or any language of the Lease to the
contrary, if the completion of Landlord’s Work is delayed by a Tenant Delay (as defined below) then Tenant shall
begin paying Rent as required under the Lease as of the date the Commencement Date would have occurred but
for  such  Tenant  Delay,  as  reasonably  evidenced  by  Landlord  to  Tenant  in  writing  prior  to  the  date  upon  which
Landlord claims that such amounts are due.

3.

Performance of Landlord’s Work. Landlord shall cause the Landlord’s Work to be performed in a
good  and  workmanlike  manner,  in  compliance  with  Legal  Requirements,  and,  except  as  set  forth  herein,  at
Landlord’s sole cost and expense. Tenant shall have the opportunity to request changes in compliance with this
Work Letter for value engineering purposes and Tenant acknowledges that any such changes may result in Tenant
Delay as further provided herein.

4.

Tenant Delay. In addition to any other occurrence expressly defined in the Lease or in this Work
Letter as Tenant Delay, “Tenant Delay” means the occurrence of any one or more of the following which cause a
delay  in  the  completion  of  Landlord’s  Work:  (i)  Tenant  is  Delinquent  (as  hereafter  defined)  in  submitting  to
Landlord any information, authorization or approvals requested by Landlord in connection with the performance
of Landlord’s Work; (ii) the performance or completion of any work or activity by a party employed by Tenant,
including any of Tenant’s employees, agents, contractors, subcontractors and materialmen, provided that Landlord
first notifies Tenant of the occurrence of such Tenant Delay upon its receipt of actual notice of such Tenant Delay;
(iii) any postponements or delays requested by Tenant and agreed to by Landlord regarding the completion of the
Landlord’s Work; (iv) any error in Landlord’s Work caused by any act or omission by Tenant or its employees or
agents where Tenant has a duty act under this Lease, provided that Landlord first notifies Tenant of the occurrence
of  such  Tenant  Delay  upon  its  receipt  of  actual  notice  of  such  Tenant  Delay;  (v)  the  performance  of  any  TI
Changes (as defined below) provided that in connection with the approval of such TI Changes Landlord provides
Tenant with a non-binding estimated amount of the Tenant Delay that may result from such TI Change; or (vi) any
other act or omission of the Tenant, where Tenant has a duty to act under the Lease or where Tenant has interfered
with Landlord’s Work, which causes a delay in the completion of Landlord’s Work, provided that Landlord first
notifies Tenant of the occurrence of such Tenant Delay upon its receipt of actual notice of such Tenant Delay. For
the purposes of this Section, the term “Delinquent” shall mean that the action or communication

Exhibit E - 3

required  of  Tenant  is  not  taken  within  five  (5)  business  days  following  written  request  (which  may  be  sent  via
electronic mail to Tenant’s Authorized Representative by Landlord’s Authorized Representative, so long as such
e-mail contains a clear statement that a failure to respond within such five (5) business day period may gave rise
to Tenant Delay hereunder) by Landlord unless a longer period of time is expressly specified in this Work Letter.
For purposes hereof, Andy Dulac and Chris Flagg (e-mail: [***]) shall be Landlord’s Authorized Representatives;
and Scott Hemphill (e-mail: [***]) shall be Tenant’s Authorized Representatives.

5.

Changes to Landlord’s Work. Tenant will have no right to make any changes (“TI Changes”) to the
Site  Plan  or  Landlord’s  Work  without  the  prior  written  consent  of  Landlord,  which  consent  shall  not  be
unreasonably  withheld,  conditioned,  or  delayed,  and  the  execution  by  Landlord  and  Tenant  of  a  written  change
order which specifies (i) the nature of the TI Changes and (ii) an estimate of the cost to Tenant as a result of such
TI  Changes.  Tenant  shall  be  solely  responsible  for  the  Costs  of  all  TI  Changes  to  the  extent  in  excess  of  the
Landlord’s Work Cost Cap including a construction management fee of five percent (5%) of the total costs of all
TI  Changes  in  excess  of  the  Landlord’s  Work  Cost  Cap  (when  aggregated  with  all  other  Costs  of  Landlord’s
Work), and, until Landlord has incurred Costs equal to the Landlord’s Work Cost Cap (in which event such Costs
shall be borne by Landlord and Tenant pro rata in accordance with the terms and conditions of Section 1 of this
Work  Letter),  Tenant  shall  pay  such  Costs  as  Additional  Rent  within  30  days  following  invoice  as  such  work
progresses,  such  invoices  to  be  issued  no  more  than  once  each  month  as  such  work  progresses,  together  with
reasonable back-up evidencing such Costs).

Within  90  days  following  the  completion  of  the  Landlord’s  Work,  Landlord  shall  provide  Tenant  with  a
final  reconciliation  of  all  Costs,  with  reasonable  back-up  evidencing  the  same,  and  Tenant  and  Landlord  shall
make  any  final  adjustments  necessary  to  ensure  that  Tenant  has  paid  the  final  amount  of  Costs  actually  due
hereunder.

6.

Prior Access. Not later than thirty (30) days prior to Substantial Completion of Landlord’s Work,
Landlord  shall  provide  Tenant  access  to  the  Premises  to  install  furniture  systems,  fixtures,  equipment  and
telephone/data equipment (collectively, “Tenant’s Work”) in preparation for Tenant’s occupancy of the Premises.
Such  access  shall  be  subject  to  scheduling  by  Landlord  in  a  reasonable  manner  intended  to  permit  Landlord  to
timely Substantially Complete the Landlord’s Work and for Tenant to timely complete the Tenant’s Work prior to
the  Commencement  Date,  without  use  of  overtime  labor.  In  connection  with  such  access,  Tenant  agrees  (a)  to
cease promptly upon notice from Landlord any Tenant’s Work which has not been approved by Landlord, where
such approval is required, or is not in compliance with the provisions of this Lease or which shall interfere with or
delay  the  performance  of  Landlord’s  Work  (the  mere  performance  of  such  work  in  accordance  with  Landlord’s
schedule  not  being  deemed  to  result  in  any  such  delay),  and  (b)  to  comply  promptly  with  all  reasonable
procedures and regulations prescribed by Landlord from time to time for coordinating the Landlord’s Work and
the Tenant’s Work, each with the other and with any other activity or work in the Building. Such access by Tenant
shall be deemed to be subject to all of the applicable provisions of the Lease, except that

Exhibit E - 4

there shall be no obligation on the part of Tenant solely because of such access to pay Base Rent or Additional
Rent  with  respect  to  the  Premises  until  otherwise  required  by  the  terms  of  the  Lease.  Without  limiting  the
foregoing,  prior  to  accessing  the  Premises,  Tenant  shall  provide  to  Landlord,  in  form  and  substance  reasonably
acceptable to Landlord: (i) a detailed description of and schedule for Tenant’s Work; (ii) the names and addresses
of all contractors, subcontractors and material suppliers and all other representatives of Tenant who or which will
be entering the Premises on behalf of Tenant to perform Tenant’s Work or will be supplying materials for such
work,  and  the  approximate  number  of  individuals,  itemized  by  trade,  who  will  be  present  in  the  Premises;  (iii)
[Intentionally Omitted]; and (iv) certificates of insurance (in amounts required by the Lease and with the parties
identified in, or required by, the Lease named as additional insureds).

If Tenant fails or refuses to comply or cause its contractors to comply with any of the obligations described
or referred to above, then immediately upon notice to Tenant, Landlord may revoke Tenant’s right to access the
Premises prior to the date of Substantial Completion of Landlord’s Work. Landlord shall assume no responsibility
for the quality or completion of the Tenant’s Work under this Section, and shall not be responsible for equipment
or supplies left or stored in the Premises by Tenant or Tenant’s contractors except to the extent of Landlord’s or its
agents  or  their  respective  employees’  gross  negligence  or  willful  misconduct.  Tenant’s  access  to  the  Premises
pursuant to this Section shall be at the sole risk of Tenant except as expressly set forth herein.
