information available to us as of the date of this Annual Report, and while we believe such information forms a reasonable basis for such statements, such
information may be limited or incomplete. Our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of,

statements.

Unless  otherwise  indicated,  information  contained  in  this  Annual  Report  concerning  our  industry  and  the  markets  in  which  we  operate,  including  our
general expectations and market position, market opportunity and market size estimates, is based on information from independent industry analysts, third-
party sources and management estimates. Management estimates are derived from publicly available information released by independent industry analysts
and third-party sources, as well as data from our internal research, and are based on assumptions made by us based on such data and our knowledge of such
industry and market, which we believe to be reasonable. In addition, while we believe the market opportunity information included in this Annual Report is
generally reliable and is based on reasonable assumptions, such data involve risks and uncertainties and are subject to change based on various factors,
including those discussed under the section of this Annual Report titled “Item 3.D—Risk Factors.”

SUMMARY RISK FACTORS

Investing in our shares involves numerous risks, including the risks described in “Item 3.D—Risk Factors” of this Annual Report on Form 20-F. Below are
some of our principal risks, any one of which could materially adversely affect our business, financial condition, results of operations, and prospects:

• We will need to raise substantial additional funding to pursue our business objectives, which may not be available on acceptable terms, or at all,
and  failure  to  obtain  this  necessary  capital  when  needed  may  force  us  to  delay,  limit  or  terminate  our  product  development  efforts,  potential
commercialization efforts or other operations.

• We have incurred significant losses since our inception and expect that we will continue to incur significant losses for the foreseeable future and

we may never achieve profitability.

•

Changes in European Union regulations may limit our ability to attract and obtain additional financing sources outside France.

• We have no approved products, which makes it difficult to assess our future prospects.

• We are heavily dependent on the success of our most advanced product candidate, eryaspase.

• We  face  substantial  competition  from  companies  with  considerably  more  resources  and  experience  than  we  have,  which  may  result  in  others

discovering, developing, receiving approval for, or commercializing products before or more successfully than us.

•

If our product candidates are not approved for marketing by applicable government authorities, we will be unable to commercialize them.

• Our product candidates will need to undergo clinical trials that are time-consuming and expensive, the outcomes of which are unpredictable, and
for which there is a high risk of failure. If clinical trials of our product candidates fail to satisfactorily demonstrate safety and efficacy to the EMA,
FDA and other regulators, we may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development
and commercialization of these product candidates.

•

•

The United States and European Union formulations of eryaspase differ, and regulatory authorities in each jurisdiction may not accept data from
alternative  eryaspase  formulations  in  other  jurisdiction(s),  which  may  result  in  delays  and  additional  costs  in  order  to  conduct  additional
comparability studies or the need to repeat nonclinical and clinical studies in order to obtain approval in each jurisdiction in which we intend to
commercialize eryaspase.

In the United States, our product candidates will be regulated as biological products, or biologics, which may subject them to competition sooner
than we currently anticipate.

• We rely on third parties to assist in our discovery and development activities, and the loss of any of our relationships with research institutions

could hinder our product development prospects.

• We rely on third parties to conduct our clinical trials and perform data collection and analysis, which may result in costs and delays that prevent us

from successfully commercializing our product candidates.

• Due to our limited resources and access to capital, our decisions to prioritize development of certain product candidates may adversely affect our

business prospects.

•

Even if we obtain marketing approvals for our product candidates, the terms of approvals and ongoing regulation of our products may limit how
we market our products, which could materially impair our ability to generate revenues.

• Our production capacity could prove insufficient for our needs.

• Our production costs may be higher than we currently estimate.

• Our failure to maintain certain tax benefits applicable to French biopharmaceutical companies may adversely affect our results of operations, our

cash flows and our financial condition.

•

The COVID-19 coronavirus could adversely impact our business, including our clinical trials.

• Our ability to compete may decline if we do not adequately protect our proprietary rights.

•

•

•

The market price of our equity securities may be volatile or may decline regardless of our operating performance.

The dual listing of our ordinary shares and our ADSs may adversely affect the liquidity and value of our ordinary shares and ADSs.

The rights of shareholders in companies subject to French corporate law differ in material respects from the rights of shareholders of corporations
incorporated in the United States.

3.D.Risk Factors

Our business faces significant risks. You should carefully consider all of the information set forth in this Annual Report and in our other filings with the
United States Securities and Exchange Commission, or the SEC, including the following risk factors which we face and which are faced by our industry.
Our business, financial condition or results of operations could be materially adversely affected by any of these risks. This report also contains forward-
looking statements that involve risks and uncertainties. Our results could materially differ from those anticipated in these forward-looking statements, as a
result of certain factors including the risks described below and elsewhere in this Annual Report and our other SEC filings. See “Special Note Regarding
Forward-Looking Statements” above.

3.D.1. Risks Related to our Financial Position and Capital Needs

We will need to raise substantial additional funding to pursue our business objectives, which may not be available on acceptable terms, or at all, and
failure  to  obtain  this  necessary  capital  when  needed  may  force  us  to  delay,  limit  or  terminate  our  product  development  efforts,  potential
commercialization efforts or other operations.

Our  Group  has  structurally  recorded  net  losses  since  its  creation.  Our  net  cash  flows  used  in  operating  activities  were  €43.3  million,  €51.7  million  and
€56.8  million  for  the  years  ended  December  31,  2019,  2020  and  2021,  respectively.  As  of  December  31,  2021,  our  cash  and  cash  equivalents  were
€33.7 million ($38.1 million) compared to €44.4 million as of December 31, 2020 which represents an annual cash and cash equivalents net use of €10.7
million.

The Company has conducted a specific review of its liquidity risk and has put in place cash preservation measures following the negative results of the
TRYbeCA-1  study.  ERYTECH  will  now  focus  its  efforts  on  its  late-stage  program  with  eryaspase  in  patients  with  hypersensitive  acute  lymphoblastic
leukemia  (ALL)  and  confirms  its  intention  to  file  a  Biologics  License  Application  (BLA)  in  the  United  States.  We  believe,  based  on  our  current
development plan, that our cash and cash equivalents as of December 31, 2021 and the sale of ERYTECH’s U.S. cell therapy manufacturing facility for a
gross amount of USD 44.5 million to Catalent closed in April 2022 and the associated cost reductions will enable us to cover our cash requirements until
mid-2024.

However,  we  will  need  to  obtain  substantial  additional  funding  to  support  our  continuing  operations  beyond  mid-2024.They  are  part  of  the  Company's
ongoing evaluation of its strategic alternatives and partnership opportunities.

Refer to Chapter "Item B.2 Our Strategy" for further information on the strategic alternatives and development and commercialization opportunities.

Identifying  potential  product  candidates  and  conducting  preclinical  testing  and  clinical  trials  is  a  time  consuming,  expensive  and  uncertain  process  that
takes years to complete, and we or any current or future collaborators may never generate the necessary data or

5

results  required  to  obtain  regulatory  approval  and  achieve  product  sales.  In  addition,  eryaspase  or  any  of  our  product  candidates,  if  approved,  may  not
achieve commercial success. Our commercial revenue, if any, will be derived from the sale of drugs that we do not expect to be commercially available for
several years, if at all. Accordingly, we will need to continue to rely on additional financing to achieve our business objectives. While we are pursuing
various financing strategies, adequate additional financing may not be available to us on acceptable terms, or at all. 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.

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

To date, we have financed our operations primarily through a combination of sale of equity securities, debt financings, including, but not limited to, the
ATM offering program and the registered direct offerings in the United States, the convertible bond financing pursuant to the OCABSA Agreement, state-
guaranteed loans in France, or PGE loans, and public assistance programs in support of innovation, such as the conditional advances and subsidies from the
Banque Publique d’Investissement, or Bpifrance, and research tax credits. Until such time, if ever, as we can generate substantial revenue from the sale of
our product candidates, we expect to continue to finance our cash needs through a combination of equity offerings, debt financings, collaborations, strategic
alliances and licensing arrangements. To the extent that we raise additional capital through the sale of equity securities or convertible debt securities, your
ownership  interest  will  be  diluted,  and  the  terms  of  these  securities  may  include  liquidation  or  other  preferences  that  adversely  affect  your  rights  as  a
shareholder. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to
take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.

We  also  implemented  a  convertible  bond  financing  with  European  High  Growth  Opportunities  Fund  in  June  2020  and  an  ATM  program  in  the  United
States, it being specified that the total number of new shares that may be issued in connection with these two instruments is capped at 20% of the number of
shares admitted to trading on Euronext Paris, including shares admitted without a prospectus during the twelve months prior to their issuance. Please refer
to “Item 10.B. Liquidity and capital resources” and “Item 10.C Material Contracts” for further information on the convertible bond financing and the ATM
program.

If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may be
required to relinquish valuable rights to our research programs 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 or other arrangements with third parties when needed, we may be required to delay, limit,
reduce or terminate our drug development or future commercialization efforts or grant rights to third parties to develop and market product candidates that
we would otherwise prefer to develop and market ourselves.

We have incurred significant losses since our inception and expect that we will continue to incur significant losses for the foreseeable future and we
may never achieve profitability.

We have not yet generated significant revenues and have incurred significant operating losses since our inception. We incurred net losses of €62.7 million,
€73.3  million  and  €53.8  million  for  the  years  ended  December  31,  2019,  2020  and  2021,  respectively;  these  losses  have  adversely  impacted,  and  will
continue to adversely impact, our equity attributable to shareholders and net assets. These losses are principally the result of our research expenditures and
development costs for conducting preclinical studies and clinical trials, as well as general and administrative expenses associated with our operations. We
anticipate that our operating losses will continue for at least the next several years as we continue our research and development activities and until we
generate substantial revenues from any approved product candidates. As of December 31, 2021, we had a total shareholders' equity of €22.8 million.

We have devoted most of our financial resources to research and development, including our clinical and preclinical development activities. The amount of
our  future  net  losses  will  depend,  in  part,  on  the  pace  and  amount  of  our  future  expenditures  and  our  ability  to  obtain  funding  through  equity  or  debt
financings,  strategic  collaborations  or  tax  credits  until  such  time,  if  ever,  as  we  can  generate  substantial  product  revenue.  We  have  not  yet  received
marketing approval for any of our product candidates. Even if we obtain regulatory approval to market a product candidate, our future revenues will depend
upon  the  size  of  any  markets  in  which  our  product  candidates  have  received  approval,  and  our  ability  to  achieve  sufficient  market  acceptance,
reimbursement from third-party payors and adequate market share for our product candidates in those markets.

We anticipate that our expenses will increase substantially as we:

•

•

continue the preclinical and clinical development of our product candidates;

expand the scope of our current clinical trials for our product candidates;

6

•

•

•

•

seek regulatory and marketing approvals for our product candidates that successfully complete clinical trials;

establish a sales, marketing and distribution infrastructure to commercialize any products for which we may obtain marketing approval and for
which we have not entered into a third-party collaboration;

seek to identify and validate additional product candidates;

acquire or in-license other product candidates and technologies;

• make milestone, royalty or other payments under in-license or collaboration agreements;

• maintain, protect and expand our intellectual property portfolio;

attract new and retain existing skilled personnel; and

create additional infrastructure or improve existing ones to support our operations.

Our operating results may fluctuate significantly from year to year, such that a period-to-period comparison of our results of operations may not be a good
indication of our future performance. In any particular period or periods, our operating results could be below the expectations of securities analysts or
investors, which could cause the price of the ordinary shares and ADSs to decline.

We  may  be  forced  to  repay  conditional  advances  prematurely  if  we  fail  to  comply  with  our  contractual  obligations  under  certain  innovation  grant
agreements.

Through December 31, 2021, we have received €2.7 million in non-refundable grants and €5.8 million in conditional advances from Bpifrance. To date,
TEDAC  is  the  only  ongoing  program  funded  by  non-refundable  grants  and  conditional  advances.  If  we  fail  to  comply  with  our  contractual  obligations
under the applicable innovation grant agreements, including if we lose our exclusive right to commercially develop our product candidates, we could be
forced to repay the conditional advances (amounting to €4.9 million at the date of this Annual Report) ahead of schedule. Such premature repayment could
adversely affect our ability to finance our research and development projects, in which case we would need to locate alternative sources of capital, which
may not be available on commercially reasonable terms or at all.

We have entered into a note and warrant transaction consisting of tranches of convertible bonds with warrants attached (OCABSA) and may encounter
adverse effects as a result thereof.

On  June  24,  2020,  we  entered  into  the  OCABSA  Agreement,  pursuant  to  which  we  may  raise  up  to  €60  million  in  the  aggregate  from  the  exercise  of
convertible notes, subject to the regulatory limit of 20% dilution, unless further authorized. The share warrants attached to the notes represent 10% of the
nominal amount of the issued notes and have an exercise price of €8.91 per share. This exercise price represents a 20% premium over the lowest volume-
weighted average daily price of the share over the reference period preceding the issue of the first tranche.

As of December 31, 2021, we issued nine tranches of €3.0 million (on July 6, 2020, August 24, 2020, November 17, 2020, December 7, 2020, December
22, 2020, March 2, 2021, May 19, 2021, July 22, 2021 and August 24, 2021), for a total amount of €27.0 million, all of which convertible notes have been
converted into ordinary shares and no warrants have been exercised. We could decide to issue additional tranches up to a maximum of €6 million until June
2022, subject to the regulatory limit of 20% dilution. There is no guarantee that we will be able to raise this maximum amount, and our ability to issue
additional tranches depends on a number of factors and conditions beyond our control.

By using this financing program, we may encounter the following adverse effects:

•

•

•

•

the rapid and frequent sale of the new shares resulting from the conversion of the convertible notes and the exercise of the share warrants by the
investor may adversely impact our share price;

the total amount of issuances of convertible notes and share warrants may depend on certain regulatory approvals making the financing amount
uncertain;

as  our  share  price  has  an  impact  on  the  number  of  shares  issued  upon  the  conversion  of  the  convertible  notes  and  the  exercise  of  the  share
warrants, the number of shares issued upon the conversion of the convertible notes and the exercise of the share warrants is uncertain and may
significantly fluctuate during the lifetime of the financing program; and

conversion into ordinary shares of all or part of the convertible notes and the exercise of all or part of the share warrants could have a potentially
significant dilutive effect for our shareholders.

As an example, a shareholder holding 1% of our share capital as of the date of this Annual Report would hold 0.51% of the share capital in the event of the
conversion of outstanding notes, the exercise of outstanding warrants and the use of all the amounts

7

remaining in the OCABSA Agreement (€33.0 million) and a share price of €1.28 (closing share price on the day before the date of this Annual Report),
subject to obtaining additional authorizations relating thereto if applicable.

3.D.2. Risks Related to Development of our Product Candidates

We have no approved products, which makes it difficult to assess our future prospects.

®

A  key  element  of  our  strategy  is  to  use  and  expand  our  proprietary  ERYCAPS   platform  to  build  a  pipeline  of  innovative  product  candidates  and  to
progress these drug candidates through clinical development for the treatment of severe forms of cancer and orphan diseases. The discovery of therapeutic
drugs  based  on  encapsulating  molecules  inside  red  blood  cells  is  an  emerging  field,  and  the  scientific  discoveries  that  form  the  basis  for  our  efforts  to
discover and develop drug candidates are relatively new. The scientific evidence to support the feasibility of developing drug candidates based on these
discoveries is both preliminary and limited. Although our research and development efforts to date have resulted in a pipeline of product candidates, we
have not yet obtained approval for any products, we have not yet generated any revenues from the sale of approved products and we may not be able to
develop product candidates that are considered to be safe and effective. Our operations to date have been limited to developing our ERYCAPS  platform
technology and undertaking preclinical studies and clinical trials of our product candidates, including our lead product candidate, eryaspase, also known as
GRASPA ,  the  approved  trade  name  for  eryaspase  in  Europe.  However,  we  have  not  yet  demonstrated  an  ability  to  overcome  many  of  the  risks  and
uncertainties frequently encountered by companies in new and rapidly evolving fields, particularly in the pharmaceutical industry. Consequently, the ability
to predict our future operating results or business prospects is more limited than if we had a longer operating history or approved products on the market.

®

®

We are heavily dependent on the success of our most advanced product candidate, eryaspase.

Our  business  and  future  success  depends  on  our  ability  to  obtain  regulatory  approval  for  and,  together  with  third-party  collaborators,  to  successfully
commercialize  our  lead  product  candidate,  eryaspase,  which  is  under  clinical  development  for  oncology  indications.  Eryaspase  is  our  only  product
candidate  in  late-stage  clinical  development,  and  our  business  currently  depends  heavily  on  its  successful  development.  As  previously  announced,  on
October 25, 2021, we reported top-line final results of our Phase 3 clinical trial of eryaspase for the treatment of second-line advanced pancreatic cancer
patients, which we refer to as the TRYbeCA-1 trial. This trial did not meet the primary efficacy endpoint of overall survival. Following the failure of our
main development project, we announced in November 2021 that we were now refocusing our operational efforts on the potential approval of eryaspase in
acute lymphoblastic leukemia, or ALL, for patients hypersensitive to pegylated asparaginase, and that our strategy is now to search for one or more partners
to support the continuation of our activity and developments

We  have  also  launched  a  Phase  2  proof-of-concept  study  in  TNBC  in  Europe  (TRYbeCA-2  study).  Following  the  announcement  of  the  failure  of  the
TRYbeCA-1  study,  we  announced  that  we  had  stopped  enrolling  new  patients  in  the  TRYbeCA-2  study.  We  expect  to  announce  the  results  of  the
TRYbeCA-2 study with respect to the few patients enrolled around mid 2022, but cannot guarantee that the results of this study will be positive or that they
will allow further development in this therapeutic indication.

Eryaspase will require additional clinical and non-clinical development, regulatory review and approval in multiple jurisdictions, substantial investment,
access  to  sufficient  commercial  manufacturing  capacity  and  significant  marketing  efforts  before  we  can  generate  any  revenue  from  product  sales.  We
cannot be certain eryaspase will receive regulatory approval or be successfully commercialized even if we receive regulatory approval. In addition, because
eryaspase is our most advanced product candidate, and because our other product candidates are based on the same ERYCAPS  platform technology, if
eryaspase encounters safety or efficacy problems, developmental delays or regulatory issues or other problems, our development plans and business would
be significantly harmed.

®

Due to our limited resources and access to financing, we are focused on prioritizing the development of our product candidates and properly allocating
resources to each of them. At the end of 2021, we decided to focus our efforts on the development of eryaspase in ALL and TNBC, which shift in focus has
required and will continue to require us to mobilize multiple resources. This choice of allocation of our human and financial resources may not lead to the
development  of  viable  drugs  and  may  divert  resources  that  could  have  been  allocated  to  more  promising  programs,  and  may  result  in  material  adverse
effects on us, our business, prospects, financial condition, financial results or development.

We may not be successful in our efforts to use and expand our ERYCAPS  platform to develop marketable products.

®

®

We believe that our ERYCAPS   platform  has  broad  potential  application  and  can  be  used  to  encapsulate  a  wide  range  of  therapeutic  agents  within  red
blood cells for which long-circulating therapeutic activity and rapid and specific targeting is desired. However, we are at an early stage of development and
our platform has not yet, and may never, lead to approved or marketable products. Even if we are successful in continuing to build our product pipeline, the
potential product candidates that we identify may not be suitable for clinical development, including for reasons related to their harmful side effects, limited
efficacy or other characteristics that indicate that they are unlikely to be products that will receive marketing approval and achieve market acceptance. Use
of red blood cells as the basis for our ERYCAPS  platform may result in similar risks that affect the ability of our products to receive marketing approval
and

®

8

achieve market acceptance. If we do not successfully develop and commercialize product candidates based upon our technological approach, we may not
be able to obtain product or collaboration revenues in future periods, which would harm our business and our prospects.

We  face  substantial  competition  from  companies  with  considerably  more  resources  and  experience  than  we  have,  which  may  result  in  others
discovering, developing, receiving approval for, or commercializing products before or more successfully than us.

The biopharmaceuticals industry is highly competitive. Numerous biopharmaceutical laboratories, biotechnology companies, institutions, universities and
other  research  entities  are  actively  involved  in  the  discovery,  research,  development  and  marketing  of  therapeutics  to  treat  severe  forms  of  cancer  and
orphan diseases, making it a highly competitive field. We have competitors in a number of jurisdictions, many of which have substantially greater name
recognition, commercial infrastructures and financial, technical and personnel resources than we have.

L-asparaginase is currently available in several forms including native, recombinant and pegylated L-asparaginase derived from Escherichia coli (E. coli)
and preparations derived from Erwinia chrysanthemi, including a recombinant Erwinia L-asparaginase approved by the FDA in 2021. The current market
primarily includes several products marketed by larger pharmaceutical companies, including Jazz Pharmaceuticals PLC, Servier and Clinigen Group PLC.
To our knowledge, there is no potential treatment being developed using non encapsulated L-asparaginase for the treatment of pancreatic cancer or other
solid tumor indications, but this may change and current marketed asparaginase products may attempt to broaden their indications. In ALL patients who
develop  hypersensitivity  to  E.  coli-derived  asparaginase,  eryaspase  could  potentially  face  competition  from  other  existing  asparaginase  products,  most
notably  Erwinia  derived  asparaginases  including  Jazz  Pharmaceuticals’  Rylaze®  and  Clinigen’s  Erwinase®/erwinaze®.  Additionally,  eryaspase  could
potentially  face  competition  from  biosimilar  and  asparaginase  product  candidates  in  earlier  stages  of  development,  including,  but  not  limited  to,  Jazz
Pharmaceuticals’ JZP341 and XoncaneTM from Xbrane. Our products and product candidates may also have to compete with other products and product
candidates in development by established pharmaceutical companies and biotechnology companies. See “Item 4.B.10 Competition” for more information.

Established  competitors  may  invest  heavily  to  quickly  discover  and  develop  novel  compounds  that  could  make  our  product  candidates  obsolete  or
uneconomical.  Any  new  product  that  competes  with  an  approved  product  may  need  to  demonstrate  compelling  advantages  in  efficacy,  convenience,
tolerability and safety to be commercially successful. Any of our product candidates that are approved in the future will also face other competitive factors,
including generic competition, which could force us to lower prices or could result in reduced sales. In addition, new products developed by others could
emerge as competitors to our product candidates. If we are not able to compete effectively against our current and future competitors, our business will not
grow and our financial condition and operations will suffer.

Intravenous administration of our product candidates could present risks that exist in relation to blood transfusions.

Our product candidates must be intravenously injected and are therefore subject to risks associated with blood transfusions and the blood type compatibility
of the donor. We currently acquire red blood cells from blood donations prepared and tested by blood banks, notably the Établissement Français du Sang,
the  New  York  Blood  Center,  the  American  Red  Cross  and  the  German  Red  Cross  Blood  Donor  Service.  However,  using  donor-derived  red  blood  cells
presents risks associated with the potential transmission of infectious agents, such as viruses, bacteria, prions and parasites, as well as risks associated with
the  development  of  allergies  or  other  complications,  such  as  allo-immunization,  post-transfusion  graft-versus-host  disease,  anaphylactic  shock  or  death.
Risks  associated  with  the  encapsulation  of  molecules  inside  red  blood  cells  may  vary  and  will  depend  on  their  toxicity.  Although  the  blood  banks  that
supply  our  red  blood  cells  follow  a  strict  preparation  process,  approved  by  health  authorities,  to  detect  and  reduce  possible  risks  for  contamination  by
infectious agents, we cannot guarantee that our product candidates will not be contaminated, which could be detrimental to our product development and
commercialization efforts.

3.D.3. Risks Related to the Discovery and Development of and Obtaining Regulatory Approval for our Product Candidates

If our product candidates are not approved for marketing by applicable government authorities, we will be unable to commercialize them.

The European Commission (following review and an opinion by the European Medicines Agency, or EMA) in the European Union, the U.S. Food and
Drug  Administration,  or  FDA,  in  the  United  States  and  comparable  regulatory  authorities  in  other  jurisdictions  must  approve  new  drug  or  biologic
candidates before they can be commercialized, marketed, promoted or sold in those territories. We must provide these regulatory authorities with data from
preclinical studies and clinical trials that demonstrate that our product candidates are safe and effective for a defined indication before they can be approved
for commercial distribution. Clinical testing is expensive, difficult to design and implement, can take many years to complete and is inherently uncertain as
to the outcome. We must provide data to ensure the identity, strength, quality and purity of the drug substance and drug product. Also, we must assure the
regulatory authorities that the characteristics and performance of the clinical batches will be replicated consistently in the commercial batches. We have
focused our development and planned commercialization efforts in the European Union and the United States.

9

®

The processes by which regulatory approvals are obtained from the European Commission and FDA to market and sell a new product are complex, require
a number of years and involve the expenditure of substantial resources. We cannot assure you that eryaspase or any of our future product candidates will
receive European Commission or FDA approval. For example, in September 2015, we submitted a Marketing Authorization Application, or MAA, to the
EMA for the approval of GRASPA  as a treatment for ALL. However, in November 2016, we announced our withdrawal of the MAA for GRASPA . In
October 2017, we resubmitted to the EMA our MAA for GRASPA  for relapsed or refractory ALL and subsequently announced our withdrawal of the
MAA for GRASPA  in June 2018. In addition, despite the advanced status of our Phase 3 TRYbeCA-1 clinical study and taking into consideration that the
primary endpoint of overall survival has not been reached, we will not submit a BLA application for this indication and have instead decided to focus our
efforts on our advanced program in ALL with a view to submitting a BLA application for this indication in the third quarter of 2022. Even if we obtain
marketing approval of any of our product candidates in a major pharmaceutical market such as the United States or the European Union, we may never
obtain approval or commercialize our products in other major markets, due to varying approval procedures or otherwise, which would limit our ability to
realize their full market potential.

®

®

®

Our product candidates will need to undergo clinical trials that are time-consuming and expensive, the outcomes of which are unpredictable, and for
which there is a high risk of failure. If clinical trials of our product candidates fail to satisfactorily demonstrate safety and efficacy to the EMA, FDA
and  other  regulators,  we  may  incur  additional  costs  or  experience  delays  in  completing,  or  ultimately  be  unable  to  complete,  the  development  and
commercialization of these product candidates.

Preclinical testing and clinical trials are long, expensive and unpredictable processes that can be subject to extensive delays. We cannot guarantee that any
clinical trials will be conducted as planned or completed on schedule, if at all. It may take several years to complete the preclinical testing and clinical
development  necessary  to  commercialize  a  product  candidate,  and  delays  or  failure  can  occur  at  any  stage.  Interim  results  of  clinical  trials  do  not
necessarily  predict  final  results,  and  success  in  preclinical  testing  and  early  clinical  trials  does  not  ensure  that  later  clinical  trials  will  be  successful.  A
number of companies in the pharmaceutical, biopharmaceutical and biotechnology industries have suffered significant setbacks in advanced clinical trials
even after promising results in earlier trials, and we cannot be certain that we will not face similar setbacks. The design of a clinical trial can determine
whether its results will support approval of a product, and flaws in the design of a clinical trial may not become apparent until the clinical trial is well
advanced.  An  unfavorable  outcome  in  one  or  more  trials  would  be  a  major  setback  for  our  product  candidates  and  for  us.  Due  to  our  limited  financial
resources,  an  unfavorable  outcome  in  one  or  more  trials  may  require  us  to  delay,  reduce  the  scope  of,  or  eliminate  one  or  more  product  development
programs, which could have a material adverse effect on our business and financial condition and on the value of our securities.

In connection with clinical testing and trials, we face a number of risks, including risks that:

•

•

•

•

•

a product candidate is ineffective, inferior to existing approved medicines, unacceptably toxic, or has unacceptable side effects;

patients may die or suffer other adverse effects for reasons that may or may not be related to the product candidate being tested;

extension studies on long-term tolerance could invalidate the use of our product;

the results may not confirm the positive results of earlier testing or trials; and

the results may not meet the level of statistical significance required by the EMA, FDA or other regulatory agencies to establish the safety and
efficacy of our product candidates.

The results of preclinical studies do not necessarily predict clinical success, and larger and later-stage clinical trials may fail to show the desired safety and
efficacy  results  despite  having  progressed  through  preclinical  studies  and  initial  clinical  trials.  Furthermore,  there  can  be  no  assurance  that  any  of  our
clinical  trials  will  ultimately  be  successful  or  support  further  clinical  development  of  any  of  our  product  candidates.  Our  clinical  trials  of  eryaspase
conducted to date have generated favorable safety and efficacy data, other than our Phase 2b clinical trial in acute myeloid leukemia for which we did not
achieve the primary endpoint. However, we may have different results in other indications. Differences in enrollment criteria and different combinations
with other treatment modalities may also lead to different outcomes in our future clinical trials. As a result, we may not observe a similarly favorable safety
or  efficacy  profile  as  in  our  prior  clinical  trials.  There  is  a  high  failure  rate  for  drugs  proceeding  through  clinical  trials.  Many  companies  in  the
pharmaceutical,  biopharmaceutical  and  biotechnology  industries  have  suffered  significant  setbacks  in  late-stage  clinical  trials  after  achieving  positive
results in early-stage development and we cannot be certain that we will not face similar setbacks. These setbacks have been caused by, among other things,
preclinical findings made while clinical trials were underway, or safety or efficacy observations made in preclinical studies and clinical trials, including
previously  unreported  adverse  events.  Moreover,  preclinical  and  clinical  data  are  often  susceptible  to  varying  interpretations  and  analyses  and  many
companies  that  believed  their  product  candidates  performed  satisfactorily  in  preclinical  studies  and  clinical  trials  nonetheless  failed  to  obtain  FDA  or
European Commission approval. In addition, we cannot assure you that in the course of potential widespread use in the future, we will not suffer setbacks
in maintaining production quality or stability.

10

If we do not successfully complete preclinical and clinical development, we will be unable to market and sell our product candidates and generate revenues.
Even  if  we  do  successfully  complete  clinical  trials,  those  results  are  not  necessarily  predictive  of  results  of  additional  trials  that  may  be  needed  before
marketing applications may be submitted to the EMA or FDA, as applicable. For instance, despite having observed favorable results and safety profile in
multiple  clinical  trials  of  eryaspase  in  patients  with  ALL,  based  on  feedback  from  the  regulatory  agencies  requiring  additional  investment,  increasingly
competitive landscape and the limited market opportunity for eryaspase with ALL, we decided in June 2018 to cease further clinical developments efforts
in ALL. In addition, our research and development costs amounted to €52.2 million, €57.6 million and €45.1 million during the years ended December 31,
2019,  2020  and  2021,  respectively.  Although  there  are  a  large  number  of  drugs  and  biologics  in  development  in  Europe,  the  United  States  and  other
countries, only a small percentage result in the submission of a marketing application, even fewer are approved for commercialization, and only a small
number  achieve  widespread  physician  and  consumer  acceptance  following  regulatory  approval.  If  our  clinical  trials  are  substantially  delayed  or  fail  to
prove the safety and effectiveness of our product candidates in development, we may not receive regulatory approval of any of these product candidates
and our business and financial condition will be materially harmed.

Delays, suspensions and terminations in our clinical trials could result in increased costs to us and delay or prevent our ability to generate revenues.

Human clinical trials are very expensive, time-consuming, and difficult to design, implement and complete. The completion of trials for eryaspase or our
other product candidates may be delayed for a variety of reasons, including delays in:

•

•

•

•

demonstrating sufficient safety and efficacy to obtain regulatory approval to commence a clinical trial;

reaching agreement on acceptable terms with prospective contract research organizations, or CROs, and clinical trial sites;

validating test methods to support quality testing of the drug substance and drug product;

obtaining sufficient quantities of the drug substance or other materials necessary to conduct clinical trials;

• manufacturing sufficient quantities of a product candidate;

•

•

•

•

obtaining approval of applications from regulatory authorities for the commencement of a clinical trial;

obtaining institutional review board, or IRB, and Ethics Committee, or EC, approval to conduct a clinical trial at a prospective clinical trial site;

determining dosing and clinical trial design; and

patient enrollment, which is a function of many factors, including the size of the patient population, the nature of the protocol, the proximity of
patients to clinical trial sites, the availability of effective treatments for the relevant disease and the eligibility criteria for the clinical trial.

For example, in our Phase 1 clinical trial in the United States in adult ALL patients, patient enrollment took longer than expected.

The  commencement  and  completion  of  clinical  trials  for  our  product  candidates  may  be  delayed,  suspended  or  terminated  due  to  a  number  of  factors,
including:

•

•

•

•

•

•

•

•

•

•

•

•

lack of effectiveness of product candidates during clinical trials;

adverse events, safety issues or side effects relating to the product candidates or their formulation;

inability to raise additional capital in sufficient amounts to continue clinical trials or development programs, which are very expensive;

the need to sequence clinical trials as opposed to conducting them concomitantly in order to conserve resources;

our inability to maintain or enter into collaborations relating to the development and commercialization of our product candidates;

our failure to conduct clinical trials in accordance with regulatory requirements;

our inability to manufacture or obtain from third parties materials sufficient for use in preclinical studies and clinical trials;

governmental or regulatory delays and changes in regulatory requirements, policy and guidelines, including mandated changes in the scope or
design of clinical trials or requests for supplemental information with respect to clinical trial results;

delays in patient enrollment, variability in the number and types of patients available for clinical trials, and lower-than anticipated retention rates
for patients in clinical trials;

difficulty in patient monitoring and data collection due to failure of patients to maintain contact after treatment;

varying interpretations of our data, and regulatory commitments and requirements by the EMA, FDA and similar regulatory agencies; and

impact of COVID-19 pandemic or unforeseen events such as the armed conflict between Russia and Ukraine.

11

For example, our Investigational New Drug application, or IND, submitted to the FDA for eryaspase was on clinical hold from its original submission in
July 2011 until March 21, 2013. Although we received acceptance from the FDA of our IND to extend our pivotal Phase 3 clinical trial of eryaspase for the
treatment  of  second-line  pancreatic  cancer  patients  to  the  United  States  in  May  2019,  we  cannot  assure  you  that  any  future  IND  will  not  be  subject  to
clinical holds.

Many of these factors may also ultimately lead to denial of our marketing application for eryaspase or our other product candidates. If we experience delay,
suspensions or terminations in a clinical trial, the commercial prospects for the related product candidate will be harmed, and our ability to generate product
revenues will be delayed or such revenues could be reduced or fail to materialize.

We  may  find  it  difficult  to  enroll  patients  in  our  clinical  trials,  which  could  delay  or  prevent  us  from  proceeding  with  clinical  trials  of  our  product
candidates.

Identifying  and  qualifying  patients  to  participate  in  clinical  trials  of  our  product  candidates  is  critical  to  our  success.  The  timing  of  our  clinical  trials
depends on our ability to recruit patients to participate, as well as completion of required follow-up periods. If patients are unwilling to enroll in our clinical
trials because of competitive clinical trials for similar patient populations or for other reasons, the timeline for recruiting patients, conducting studies and
obtaining  regulatory  approval  of  our  product  candidates  may  be  delayed.  These  delays  could  result  in  increased  costs,  delays  in  advancing  our  product
candidates, delays in testing the effectiveness of our product candidates or termination of clinical trials altogether.

Some  of  our  current  product  candidates  are  being  developed  to  treat  severe  forms  of  cancer  and  other  orphan  diseases,  which  are  generally  defined  as
having a patient population of fewer than 200,000 individuals in the United States. We may not be able to initiate or continue clinical trials if we cannot
enroll a sufficient number of eligible patients to participate in the clinical trials required by the FDA, EMA or other regulatory authorities. Also, we may
not be able to identify, recruit and enroll a sufficient number of patients, or those with required or desired characteristics, to complete our clinical trials in a
timely manner. Patient enrollment can be affected by many factors, including:

•

•

•

•

•

•

•

•

•

•

size of the patient population and process for identifying patients;

eligibility and exclusion criteria for our clinical trials;

perceived risks and benefits of our product candidates;

severity of the disease under investigation;

proximity and availability of clinical trial sites for prospective patients;

ability to obtain and maintain patient consent;

patient drop-outs prior to completion of clinical trials;

patient referral practices of physicians;

ability to monitor patients adequately during and after treatment ; and

COVID-19 pandemic or unforeseen events such as the armed conflict between Russia and Ukraine.

Our ability to successfully initiate, enroll and complete clinical trials in any foreign country is subject to numerous risks unique to conducting business in
foreign countries, including:

•

•

•

•

difficulty in establishing or managing relationships with CROs and physicians;

different standards for the conduct of clinical trials;

inability to locate qualified local consultants, physicians and partners; and

the potential burden of complying with a variety of foreign laws, medical standards and regulatory requirements, including the regulation of
pharmaceutical and biotechnology products and treatment.

If we have difficulty enrolling a sufficient number of patients or finding additional clinical trial sites to conduct our clinical trials as planned, we may need
to delay, limit or terminate ongoing or planned clinical trials, any of which could have an adverse effect on our business, financial condition, results of
operations and prospects.

Changes in regulatory requirements, guidance from regulatory authorities or unanticipated events during the clinical trials of our product candidates
could necessitate changes to clinical trial protocols or additional clinical trial requirements, which would result in increased costs to us and could delay
our development timeline.

Changes in regulatory requirements, FDA guidance or guidance from the EMA or other European Union regulatory authorities, or unanticipated events
during our clinical trials, may force us to amend clinical trial protocols. The regulatory authorities could also

12

impose additional clinical trial requirements. Amendments to our clinical trial protocols would require resubmission to the FDA, EMA, national clinical
trial  regulators,  IRBs  and  ECs  for  review  and  approval,  which  may  adversely  impact  the  cost,  timing  or  successful  completion  of  a  clinical  trial.  If  we
experience  delays  completing,  or  if  we  terminate,  any  of  our  clinical  trials,  or  if  we  are  required  to  conduct  additional  clinical  trials,  the  commercial
prospects for our product candidates may be harmed and our ability to generate product revenue will be delayed.

The  United  States  and  European  Union  formulations  of  eryaspase  differ,  and  regulatory  authorities  in  each  jurisdiction  may  not  accept  data  from
alternative eryaspase formulations in other jurisdiction(s), which may result in delays and additional costs in order to conduct additional comparability
studies  or  the  need  to  repeat  nonclinical  and  clinical  studies  in  order  to  obtain  approval  in  each  jurisdiction  in  which  we  intend  to  commercialize
eryaspase.

The formulations of eryaspase used to conduct clinical trials in the United States and the European Union have differed in composition, manufacturing
process and release specifications. After seeking feedback from regulatory agencies, we have conducted studies to harmonize the formulation of eryaspase,
including in vitro comparability studies and stability studies. Even with this additional data, regulatory authorities may not find it acceptable to support the
approval of eryaspase. If regulatory authorities require us to generate additional nonclinical or clinical data, the generation of additional data could result in
submission delays and additional costs in order to obtain marketing approval of eryaspase.

In the United States, our product candidates will be regulated as biological products, or biologics, which may subject them to competition sooner than
we currently anticipate.

The  Biologics  Price  Competition  and  Innovation  Act  of  2009,  or  BPCIA,  was  enacted  as  part  of  the  2010  enactments  of  the  Patient  Protection  and
Affordable  Care  Act,  as  amended  by  the  Health  Care  and  Education  Reconciliation  Act  of  2010,  or  collectively,  the  Affordable  Care  Act  (ACA),  to
establish an abbreviated licensure pathway for biological products shown to be biosimilar to, or interchangeable with, an FDA-licensed biological reference
product. “Biosimilarity” means that the biological product is highly similar to the reference product notwithstanding minor differences in clinically inactive
components  and  there  are  no  clinically  meaningful  differences  between  the  biological  product  and  the  reference  product  in  terms  of  safety,  purity,  and
potency  of  the  product.  To  meet  the  higher  standard  of  “interchangeability,”  an  applicant  must  provide  sufficient  information  to  show  biosimilarity  and
demonstrate  that  the  biological  product  can  be  expected  to  produce  the  same  clinical  result  as  the  reference  product  in  any  given  patient  and,  if  the
biological product is administrated more than once to an individual, the risk in terms of safety or diminished efficacy of alternating or switching between
the use of the biological product and the reference product is not greater than the risk of using the reference product without such alternation or switch.

Under the BPCIA, an application for a biosimilar or interchangeable product cannot be approved by the FDA until 12 years after the reference product was
first licensed, and the FDA will not even accept an application for review until four years after the date of first licensure. The law is evolving, complex and
is still being interpreted and implemented by the FDA. As a result, its ultimate impact, implementation, and meaning are subject to uncertainty. While it is
uncertain when such processes intended to implement BPCIA may be fully adopted by the FDA, any such processes could have a material adverse effect
on the future commercial prospects for our biological products.

We believe that any of our product candidates approved as a biological product under a Biologics License Application, or BLA, should qualify for the 12-
year period of exclusivity. However, there is a risk that this exclusivity could be shortened due to congressional action or otherwise, potentially creating the
opportunity for biosimilar or interchangeable competition sooner than we currently anticipate. Moreover, the process by which an interchangeable product,
once  approved,  will  be  substituted  for  any  one  of  our  reference  products  in  a  way  that  is  similar  to  traditional  generic  substitution  for  non-biological
products,  such  as  drugs,  is  not  yet  clear,  and  will  depend  on  a  number  of  marketplace  and  regulatory  factors  that  are  still  developing  and  subject  to
interpretation.

Even though we have obtained orphan drug designation from the FDA and the European Commission for eryaspase for the treatment of pancreatic
cancer, ALL and AML, we may not be able to obtain orphan drug marketing exclusivity for any of our other product candidates for other indications.

Regulatory  authorities  in  some  jurisdictions,  including  the  United  States  and  the  European  Union,  may  designate  drugs  for  relatively  small  patient
populations as orphan drugs. Under the Orphan Drug Act (1983), the FDA may designate a drug as an orphan drug if it is intended to treat a rare disease or
condition, which is generally defined as a patient population of fewer than 200,000 individuals annually in the United States. Similarly, in the European
Union, a medicinal product may receive orphan designation under Article 3 of Regulation (EC) 141/2000, as amended. This applies to products that are
intended for a life-threatening or chronically debilitating condition and either the condition affects no more than five in 10,000 (5/10,000) persons in the
European Union when the application is made or the product, without the benefits derived from orphan status, would unlikely generate sufficient return in
the  European  Union  to  justify  the  necessary  investment.  Moreover,  in  order  to  obtain  orphan  designation  in  the  European  Union,  it  is  necessary  to
demonstrate that there exists no satisfactory method of diagnosis, prevention or treatment of the condition authorized for marketing in the European Union,
or if such a method exists, that the product will be of significant benefit to those affected by the condition. The EMA will reassess whether GRASPA®
continues to meet the criteria for orphan drug designation in the European Union at the time it

13

reviews a marketing authorization application for the product. If the EMA considers that GRASPA® no longer meets these criteria, for example, because it
does not offer a significant benefit over existing therapies, it may propose that the European Commission revoke GRASPA®’s orphan drug designation
prior to approval.

®

The European Commission has granted orphan drug designation for GRASPA  for the treatment of pancreatic cancer, ALL and AML, and the FDA has
granted orphan drug designation for eryaspase for the same indications. We may seek orphan drug designation for our other product candidates, and with
respect to other indications. Generally, if a drug with an orphan drug designation subsequently receives the first marketing approval for the indication for
which  it  has  such  designation,  the  drug  is  entitled  to  a  period  of  marketing  exclusivity,  which  precludes  the  FDA  from  approving  another  marketing
application for the same drug for that time period or the European Commission or any other medicines regulator in the European Union from approving a
similar medicinal product. The applicable period is seven (7) years in the United States and usually 10 years in the European Union. The European Union
exclusivity period can be reduced to six (6) years if a drug no longer meets the criteria for orphan drug designation or if the drug is sufficiently profitable so
that  market  exclusivity  is  no  longer  justified.  This  exclusivity  period  may  increase  to  12  years  if,  among  other  things,  the  MAA  includes  the  results  of
studies from an agreed pediatric investigation plan. Orphan drug exclusivity may be lost if the FDA or 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.

Even  if  we  obtain  orphan  drug  exclusivity  for  a  product  candidate,  that  exclusivity  may  not  effectively  protect  the  candidate  from  competition  because
different  drugs  can  be  approved  for  the  same  condition.  Even  after  an  orphan  drug  is  approved,  the  applicable  regulatory  authority  can  subsequently
approve another drug for the same condition if it concludes that the later drug is clinically superior in that it is shown to be safer, more effective or makes a
major contribution to patient care. Similarly, if our competitors are able to obtain orphan product exclusivity for their products in the same indications for
which we are developing our product candidates, we may not be able to have our products approved by the applicable regulatory authority for a significant
period of time.

In the European Union, GRASPA  contains a known active substance, which would undermine its data and marketing exclusivities; however, this will
not affect GRASPA ’s orphan product exclusivity.

®

®

In the European Union, data exclusivity refers to the period of time during which another company cannot refer to our data held in the authority’s files in
support of its marketing authorization. The subsequent market exclusivity refers to the period of time during which another company may use our data in
support of its marketing authorization for a generic, hybrid or biosimilar product, but the product in question may not be placed on the market. For products
containing  new  active  substances,  this  effectively  prevents  certain  products,  such  as  generics  and  similar  biological  products,  from  being  placed  on  the
market during the combined data and marketing exclusivity period. This combined period usually lasts for 10 years from the date of approval of the product
containing the new active substance.

Because the active ingredient in GRASPA  is not a new active substance, the 10-year period of protection against generics and similar biological products
is undermined. Competitors developing such products could receive European Union marketing authorizations and place their products on the European
®
Union market within 10 years of GRASPA ’s own marketing authorization, if obtained.

®

®

However, if we still have orphan drug designation for GRASPA  in the treatments of pancreatic cancer, ALL and AML in the European Union at the time
we  receive  marketing  approval  from  the  European  Commission  in  these  indications,  we  would  still  benefit  from  the  independent  period  of  market
exclusivity afforded to orphan products. In the European Union, this is usually a period of 10 years from the date of marketing approval. The exclusivity
period can be reduced to six years if a drug no longer meets the criteria for orphan drug designation or if the drug is sufficiently profitable so that market
exclusivity is no longer justified. The exclusivity period may increase to 12 years if, among other things, the MAA includes the results of studies from an
agreed pediatric investigation plan. During the orphan exclusivity period, regulators should not accept or approve applications for the approval of a similar
medicine for the same therapeutic indication, unless the second product is demonstrably safer, more effective or otherwise clinically superior. Regulators
®
may approve different products for the same condition as GRASPA .

We rely on third parties to assist in our discovery and development activities, and the loss of any of our relationships with research institutions could
hinder our product development prospects.

We currently have and expect to continue to depend on collaborations with public and private research institutions to conduct some of our early-stage drug
discovery activities. If we are unable to enter into research collaborations with these institutions, or if any one of these institutions fails to work efficiently
with us, the research, development or marketing of our product candidates planned as part of the research collaboration could be delayed or canceled. In the
event a research agreement is terminated or we become no longer in a position to renew the arrangement under acceptable conditions, our drug discovery
and development activities may also be delayed.

14

We rely on third parties to conduct our clinical trials and perform data collection and analysis, which may result in costs and delays that prevent us
from successfully commercializing our product candidates.

We rely, and will rely in the future, on medical institutions, clinical investigators, CROs, contract laboratories and collaborators to perform data collection
and analysis and to carry out our clinical trials.

For  example,  in  June  2019,  we  entered  in  an  exclusive  worldwide  license  agreement  with  SQZ  Biotechnologies  pursuant  to  which  we  and  SQZ
Biotechnologies will focus on the development of novel red blood cell-based therapeutics for the treatment of immuno-oncology and tolerance induction.
Our other main subcontractors and key partners include Établissement Français du Sang, the American Red Cross, the New York Blood Center, Medac
GmbH, the German Red Cross Blood Donor Service and Catalent.

Our development activities or clinical trials conducted in reliance on third parties may be delayed, suspended, or terminated if:

•

the third parties do not devote a sufficient amount of time or effort to our activities or otherwise fail to successfully carry out their contractual
duties or to meet regulatory obligations or expected deadlines;

• we replace a third party; or

•

the  quality  or  accuracy  of  the  data  obtained  by  third  parties  is  compromised  due  to  their  failure  to  adhere  to  clinical  protocols,  regulatory
requirements, or for other reasons.

We generally would not have the ability to control the performance of third parties in their conduct of development activities. In the event of a default,
bankruptcy or shutdown of, or a dispute with, a third party, we may be unable to enter into a new agreement with another third party on commercially
acceptable terms. Further, third-party performance failures may increase our development costs, delay our ability to obtain regulatory approval, and delay
or  prevent  the  commercialization  of  our  product  candidates.  In  addition,  our  third-party  agreements  usually  contain  a  clause  limiting  such  third  party’s
liability, such that we may not be able to obtain full compensation for any losses we may incur in connection with the third party’s performance failures.
While we believe that there are numerous alternative sources to provide these services, in the event that we seek such alternative sources, we may not be
able to enter into replacement arrangements without incurring delays or additional costs.

We may enter into collaboration agreements with third parties for the development and commercialization of our product candidates, which may affect
our ability to generate revenues.

We  have  limited  capabilities  for  product  development  and  may  seek  to  enter  into  collaborations  with  third  parties  for  the  development  and  potential
commercialization  of  our  product  candidates.  For  example,  in  June  2019,  we  entered  into  a  collaboration  with  SQZ  Biotechnologies  to  focus  on  the
development of novel red blood-cell based therapeutics for the treatment of immuno-oncology and tolerance induction. Should we seek to collaborate with
any additional third parties with respect to a prospective development program, we may not be able to locate a suitable collaborator and may not be able to
enter  into  an  agreement  on  commercially  reasonable  terms  or  at  all.  Even  if  we  succeed  in  securing  collaborators  for  the  development  and
commercialization  of  our  product  candidates,  we  will  have  limited  control  over  the  amount  and  timing  that  our  collaborators  may  dedicate  to  the
development or commercialization of our product candidates. These collaborations pose a number of risks, including the following:

•

•

•

•

•

•

collaborators  may  not  have  sufficient  resources  or  decide  not  to  devote  the  necessary  resources  due  to  internal  constraints  such  as  budget
limitations, lack of human resources, or a change in strategic focus;

collaborators may believe our intellectual property is not valid or is unenforceable or the product candidate infringes on the intellectual property
rights of others;

collaborators may dispute their responsibility to conduct development and commercialization activities pursuant to the applicable collaboration,
including the payment of related costs or the division of any revenues;

collaborators may decide to pursue a competitive product developed outside of the collaboration arrangement;

collaborators may not be able to obtain, or believe they cannot obtain, the necessary regulatory approvals; or

collaborators  may  delay  the  development  or  commercialization  of  our  product  candidates  in  favor  of  developing  or  commercializing  another
party’s product candidate.

Thus, collaboration agreements may not lead to development or commercialization of product candidates in the most efficient manner or at all.

Some  collaboration  agreements  are  terminable  without  cause  on  short  notice.  Once  a  collaboration  agreement  is  signed,  it  may  not  lead  to
commercialization of a product candidate. We also face competition in seeking out collaborators. If we are unable to secure new collaborations that achieve
the collaborator’s objectives and meet our expectations, we may be unable to advance our product candidates and may not generate meaningful revenues.

15

Due  to  our  limited  resources  and  access  to  capital,  our  decisions  to  prioritize  development  of  certain  product  candidates  may  adversely  affect  our
business prospects.

Because we have limited resources and access to capital to fund our operations, we must decide which product candidates to pursue and the amount of
resources to allocate to each. As such, we are currently primarily focused on the development of eryaspase for the treatment of pancreatic cancer and other
solid tumors. Our decisions concerning the allocation of research, collaboration, management and financial resources toward particular compounds, product
candidates  or  therapeutic  areas  may  not  lead  to  the  development  of  viable  commercial  products  and  may  divert  resources  away  from  more  promising
opportunities.  Similarly,  our  potential  decisions  to  delay,  terminate  or  collaborate  with  third  parties  with  respect  to  some  of  our  product  development
programs may also prove not to be optimal and could cause us to miss valuable opportunities. If we do not accurately evaluate the commercial potential or
target  market  for  a  particular  product  candidate,  we  may  relinquish  valuable  rights  to  that  product  candidate  through  collaboration,  licensing  or  other
arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights. If we make incorrect
determinations regarding the market potential of our product candidates or misread trends in the pharmaceutical industry, our business prospects could be
harmed.

3.D.4. Risks Related to the Commercialization of Our Product Candidates

Even if we successfully complete clinical trials of our product candidates, those candidates may not be commercialized successfully for other reasons.

Even if we successfully complete clinical trials for one or more of our product candidates and obtain relevant regulatory approvals, those candidates may
not be commercialized for other reasons, including:

•

•

•

•

•

•

•

failing to receive regulatory clearances required to market them as drugs;

being subject to proprietary rights held by others;

failing to obtain clearance from regulatory authorities on the manufacturing of our products;

being difficult or expensive to manufacture on a commercial scale;

having adverse side effects that make their use less desirable;

failing to compete effectively with products or treatments commercialized by competitors; or

failing to show that the long-term benefits of our products exceed their risks.

Even if any of our product candidates are commercialized, they may fail to achieve the degree of market acceptance by physicians, patients, third-party
payors or the medical community in general necessary for commercial success.

Even if the medical community accepts a product as safe and efficacious for its indicated use, physicians may choose to restrict the use of the product if we
are unable to demonstrate that, based on experience, clinical data, side-effect profiles and other factors, our product is preferable to any existing drugs or
treatments. We cannot predict the degree of market acceptance of any product candidate that receives marketing approval, which will depend on a number
of factors, including, but not limited to:

•

•

•

•

•

•

•

the demonstration of the clinical efficacy and safety of the product;

the approved labeling for the product and any required warnings;

the advantages and disadvantages of the product compared to alternative treatments;

our ability to educate the medical community about the safety and effectiveness of the product;

the experience of clinicians with other potential treatments that use red blood cells to deliver therapeutics;

the coverage and reimbursement policies of government and commercial third-party payors pertaining to the product; and

the market price of our product relative to competing treatments.

If we are unable to establish sales, marketing and distribution capabilities for our product candidates, through partnership with a third party, we may
not be successful in commercializing those product candidates if and when they are approved.

We  do  not  have  a  sales  or  marketing  infrastructure  and  have  no  experience  in  the  sale,  marketing  or  distribution  of  pharmaceutical  drugs.  To  achieve
commercial success for eryaspase in TNBC and ALL, and to advance the BLA application that we currently expect to submit in the third quarter of 2022,
we  will  need  to  establish  a  sales  and  marketing  partnership  to  co-promote  those  products.  We  currently  do  not  have  sufficient  marketing  and  sales
capacities, and we have shifted our focus to finding one or more marketing partnerships, particularly in ALL. Our development and our ability to generate
revenues may therefore depend on our capacity to enter into partnerships and commercialize our products on suitable terms.

16

The conclusion of a collaboration agreement include the following risks :

•

•

the  partnership:  we  may  not  be  able  to  enter  into  an  agreement  on  commercially  reasonable  terms  (for  example,  we  could  be  required  to
continue the development of a product candidate, even if the counterpart received under the partnership agreement is not sufficient to cover our
costs);

the partner: risks relating to our intellectual property rights being challenged, risk related to the partner in obtaining regulatory authorizations,
risk related to the partner in the partner encountering difficulties or not putting in place all the resources necessary for the commercial success of
our products, or conflicts arising between us and some partners. In particular, we cannot guarantee that none of our partners will design or seek
to  implement  a  commercial  activity  using  products  that  compete  with  our  products.  Any  failure,  delay  or  default  by  the  partner  in  the
commercialization of eryaspase, particularly in ALL, would have an adverse effect on the revenues we could receive from the partnership.

If we are unable to find industrial partners in order to obtain financing and to benefit from their expertise and commercial structures already in place, the
commercialization  of  eryaspase  in  ALL  could  be  difficult  or  compromised,  despite  the  potential  approval.  We  will  therefore  need  to  incur  additional
expenses,  mobilize  management  resources,  recruit  specific  personnel,  call  upon  new  skills  and  take  the  time  necessary  to  put  in  place  the  appropriate
organization  and  structure  to  support  the  development  of  the  product  in  accordance  with  applicable  legislation  and,  more  generally,  to  optimize  its
marketing efforts. There can be no assurance that we will be able to establish or maintain relationships with third parties to market its products. Such events
could have a material adverse effect on the Company's business, prospects, results, financial condition and development.

Even if we obtain marketing approvals for our product candidates, the terms of approvals and ongoing regulation of our products may limit how we
market our products, which could materially impair our ability to generate revenues.

Even if we receive regulatory approval for a product candidate, this approval may carry conditions that limit the market for the product or put the product at
a competitive disadvantage relative to alternative therapies. For instance, a regulatory approval may limit the indicated uses for which we can market a
product or the patient population that may utilize the product or may be required to carry a warning in its labeling and on its packaging. Products with
boxed warnings are subject to more restrictive advertising regulations than products without such warnings. These restrictions could make it more difficult
to  market  any  product  candidate  effectively.  Accordingly,  assuming  we  receive  marketing  approval  for  one  or  more  of  our  product  candidates,  we  will
continue to expend time, money and effort in all areas of regulatory compliance.

Government  restrictions  on  pricing  and  reimbursement,  as  well  as  other  healthcare  payor  cost-containment  initiatives,  may  negatively  impact  our
ability to generate revenues even if we obtain regulatory approval to market a product.

Our  ability  to  commercialize  any  products  successfully  also  will  depend  in  part  on  the  extent  to  which  coverage  and  adequate  reimbursement  for  these
products  and  related  treatments  will  be  available  from  government  health  administration  authorities,  private  health  insurers  and  other  organizations.
Government authorities and other third-party payors, such as private health insurers and health maintenance organizations, determine which medications
they will cover and establish reimbursement levels. Assuming we obtain coverage for a given product by a third-party payor, the resulting reimbursement
payment  rates  may  not  be  adequate  or  may  require  co-payments  that  patients  find  unacceptably  high.  Patients  who  are  prescribed  medications  for  the
treatment of their conditions, and their prescribing physicians, generally rely on third-party payors to reimburse all or part of the costs associated with their
prescription drugs. Patients are unlikely to use our products unless coverage is provided and reimbursement is adequate to cover all or a significant portion
of the cost of our products. Therefore, coverage and adequate reimbursement is critical to new product acceptance. Coverage decisions may depend upon
clinical  and  economic  standards  that  disfavor  new  drug  products  when  more  established  or  lower  cost  therapeutic  alternatives  are  already  available  or
subsequently become available.

Government authorities and other third-party payors are developing increasingly sophisticated methods of controlling healthcare costs, such as by limiting
coverage and the amount of reimbursement for particular medications. Increasingly, third-party payors are requiring that drug companies provide them with
predetermined discounts from list prices as a condition of coverage, are using restrictive formularies and preferred drug lists to leverage greater discounts in
competitive classes and are challenging the prices charged for medical products. In addition, in the United States, federal programs impose penalties on
drug manufacturers in the form of mandatory additional rebates and/or discounts if commercial prices increase at a rate greater than the Consumer Price
Index-Urban, and these rebates and/or discounts, which can be substantial, may impact our ability to raise commercial prices. Further, no uniform policy
requirement  for  coverage  and  reimbursement  for  drug  products  exists  among  third-party  payors  in  the  United  States.  Therefore,  coverage  and
reimbursement for drug products can differ significantly from payor to payor. As a result, the coverage determination process is often a time-consuming
and costly process that will require us to provide scientific and clinical support for the use of our products to each payor separately, with no assurance that
coverage and adequate reimbursement will be applied consistently or obtained in the first instance.

17

The continuing efforts of governments, insurance companies, managed care organizations and other payors of healthcare costs to contain or reduce costs of
healthcare may negatively affect our commercialization prospects, including:

•

•

•

•

our ability to set a price we believe is fair for our products, if approved;

our ability to obtain and maintain market acceptance by the medical community and patients;

our ability to generate revenues and achieve profitability; and

the availability of capital.

We cannot be sure that coverage and reimbursement will be available for any potential product candidate that we may commercialize and, if reimbursement
is available, what the level of reimbursement will be. Coverage and reimbursement may impact the demand for, or the price of, any product candidate for
which we obtain marketing approval. If coverage and reimbursement are not available or reimbursement is available only to limited levels, we may not
successfully commercialize any product candidate for which we obtain marketing approval. Even if favorable coverage and reimbursement status is
attained for one or more products for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented
in the future.

In  the  United  States,  the  ACA  is  significantly  impacting  the  provision  of,  and  payment  for,  healthcare.  Various  provisions  of  the  ACA  are  designed  to
expand Medicaid eligibility, subsidize insurance premiums, provide incentives for businesses to provide healthcare benefits, prohibit denials of coverage
due to pre-existing conditions, establish health insurance exchanges, and provide additional support for medical research. With regard to pharmaceutical
products  specifically,  the  ACA,  among  other  things,  expanded  and  increased  industry  rebates  for  drugs  covered  under  Medicaid  programs  and  made
changes to the coverage requirements under the Medicare prescription drug benefit.

There have been executive, judicial and Congressional challenges to certain aspects of the ACA. For example, since January 2017, President Trump signed
several Executive Orders and other directives designed to delay the implementation of certain provisions of the ACA or otherwise circumvent some of the
requirements  for  health  insurance  mandated  by  the  ACA.  Concurrently,  the  U.S.  Congress  has  considered  legislation  that  would  repeal  or  repeal  and
replace all or part of the ACA. While Congress has not passed comprehensive repeal legislation, several bills affecting the implementation of certain taxes
under the ACA have been signed into law. Legislation enacted in 2017, informally titled the Tax Cuts and Jobs Act, or the Tax Act, included a provision
which repealed, effective January 1, 2019, the tax-based shared responsibility payment imposed by the ACA 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.”  The  2020  federal  spending  package
permanently  eliminated,  effective  January  1,  2020,  the  ACA-mandated  “Cadillac”  tax  on  high-cost  employer-sponsored  health  coverage  and  medical
device  tax  and,  effective  January  1,  2021,  also  eliminates  the  health  insurer  tax.  The  Bipartisan  Budget  Act  of  2018,  or  the  BBA,  among  other  things,
amended  the  ACA,  effective  January  1,  2019,  to  increase  from  50  percent  to  70  percent  the  point-of-sale  discount  that  is  owed  by  pharmaceutical
manufacturers who participate in Medicare Part D and to close the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole.”
For example, on June 17, 2021 the U.S. Supreme Court dismissed a challenge on procedural grounds that argued the ACA is unconstitutional in its entirety
because the “individual mandate” was repealed by Congress. Thus, the ACA will remain in effect in its current form. Further, prior to the U.S. Supreme
Court  ruling,  on  January  28,  2021,  President  Biden  issued  an  executive  order  to  initiate  a  special  enrollment  period  for  purposes  of  obtaining  health
insurance coverage through the ACA marketplace. The executive order also instructs certain governmental agencies to review and reconsider their existing
policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include
work  requirements,  and  policies  that  create  unnecessary  barriers  to  obtaining  access  to  health  insurance  coverage  through  Medicaid  or  the  ACA.  It  is
unclear how any such challenges and healthcare reform measures of the Biden administration will impact ACA and our business.

In addition, both the Budget Control Act of 2011 and the American Taxpayer Relief Act of 2012 have instituted, among other things, mandatory reductions
in Medicare payments to certain providers. The Budget Control Act of 2011, among other things, includes reductions to Medicare payments to providers of
2% per fiscal year, which went into effect on April 1, 2013 and, due to subsequent legislative amendments to the statute will remain in effect through 2031,
except for a temporary suspension from May 1, 2020 through March 31, 2022 due to the COVID-19 pandemic, unless additional Congressional action is
taken. Under current legislation, the actual reduction in Medicare payments will vary from 1% in 2022 to up to 3% in the final fiscal year of this sequester.
On  March  11,  2021,  President  Biden  signed  the  American  Rescue  Plan  Act  of  2021  into  law,  which  eliminates  the  statutory  Medicaid  drug  rebate  cap,
currently set at 100% of a drug’s average manufacturer price, for single source and innovator multiple source drugs, beginning January 1, 2024. On January
2,  2013,  the  American  Taxpayer  Relief  Act  of  2012  was  signed  into  law,  which,  among  other  things,  reduced  Medicare  payments  to  several  providers,
including  hospitals,  and  increased  the  statute  of  limitations  period  for  the  government  to  recover  overpayments  to  providers  from  three  to  five  years.
Additional legislative proposals to reform healthcare and government insurance programs, along with the trend toward managed healthcare in the United
States, could influence the purchase of medicines and reduce reimbursement and/or coverage of our product candidates, if approved.

Recently, there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products. Such scrutiny
has resulted in several recent U.S. Congressional inquiries and proposed and enacted federal and state

18

legislation  designed  to,  among  other  things,  bring  more  transparency  to  drug  pricing,  review  the  relationship  between  pricing  and  manufacturer  patient
programs, reduce the costs of drugs under Medicare and reform government program reimbursement methodologies for drug products. At the federal level,
the Trump administration used several means to propose implementing drug pricing reform, including through federal budget proposals, executive orders
and  policy  initiatives.  For  example,  on  July  24,  2020  and  September  13,  2020,  the  Trump  administration  announced  several  executive  orders  related  to
prescription  drug  pricing  that  seek  to  implement  several  of  the  administration’s  proposals.  As  a  result,  the  FDA  released  a  final  rule  and  guidance  on
September 24, 2020, providing guidance for states to build and submit importation plans for drugs from Canada. Further, on November 20, 2020, the U.S.
Department of Health and Human Services finalized a regulation removing safe harbor protection for price reductions from pharmaceutical manufacturers
to plan sponsors under Part D, either directly or through pharmacy benefit managers, unless the price reduction is required by law. The implementation of
the rule has been delayed by the Biden administration from January 1, 2022 to January 1, 2023 in response to ongoing litigation. The rule also creates a
new safe harbor for price reductions reflected at the point-of-sale, as well as a safe harbor for certain fixed fee arrangements between pharmacy benefit
managers and manufacturers, the implementation of which have also been delayed pending review by the Biden administration until January 1, 2023. On
November 20, 2020, the Centers for Medicare & Medicaid Services, or CMS, issued an interim final rule implementing President Trump’s Most Favored
Nation executive order, which would tie Medicare Part B payments for certain physician-administered drugs to the lowest price paid in other economically
advanced countries. As a result of litigation challenging the Most Favored Nation model, on December 27, 2021, CMS published a final rule that rescinded
the  Most  Favored  Nation  model  interim  final  rule.  In  July  2021,  the  Biden  administration  released  an  executive  order,  “Promoting  Competition  in  the
American Economy,” with multiple provisions aimed at prescription drugs. In response to Biden’s executive order, on September 9, 2021, HHS released a
Comprehensive Plan for Addressing High Drug Prices that outlines principles for drug pricing reform and sets out a variety of potential legislative policies
that  Congress  could  pursue  to  advance  these  principles.  No  legislation  or  administrative  actions  have  been  finalized  to  implement  these  principles.  In
addition, Congress is considering drug pricing as part of other reform initiatives. At the state level, legislatures have increasingly passed legislation and
implemented  regulations  designed  to  control  pharmaceutical  and  biological  product  pricing,  including  price  or  patient  reimbursement  constraints,
discounts,  restrictions  on  certain  product  access  and  marketing  cost  disclosure  and  transparency  measures,  and,  in  some  cases,  designed  to  encourage
importation from other countries and bulk purchasing.

We expect that the ACA, as well as other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and
lower  reimbursement,  and  in  additional  downward  pressure  on  the  price  that  we  receive  for  any  approved  product  candidate.  Any  reduction  in
reimbursement  from  Medicare  or  other  government-funded  programs  may  result  in  a  similar  reduction  in  payments  from  private  payors.  The
implementation  of  cost  containment  measures  or  other  healthcare  reforms  may  prevent  us  from  being  able  to  generate  revenue,  attain  profitability  or
commercialize our drugs. Moreover, we cannot predict what healthcare reform initiatives may be adopted in the future.

In some foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. In addition, in some foreign markets, the
pricing  of  prescription  drugs  is  subject  to  government  control  and  reimbursement  may  in  some  cases  be  unavailable.  The  requirements  governing  drug
pricing vary widely from country to country. For example, the European Union provides options for its member states to restrict the range of medicinal
products  for  which  their  national  health  insurance  systems  provide  reimbursement  and  to  control  the  prices  of  medicinal  products  for  human  use.  A
member state may approve a specific price for the medicinal product, may refuse to reimburse a product at the price set by the manufacturer or may instead
adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. There can be no assurance that
any  country  that  has  price  controls  or  reimbursement  limitations  for  biopharmaceutical  products  will  allow  favorable  reimbursement  and  pricing
arrangements  for  eryaspase  or  any  of  our  other  product  candidates  that  may  be  approved.  Historically,  biopharmaceutical  products  launched  in  the
European Union do not follow price structures of the United States and generally tend to have significantly lower prices.

Moreover, in the EU some countries may require the completion of additional studies that compare the cost-effectiveness of a particular medicinal product
candidate to currently available therapies. This Health Technology Assessment, or HTA process, which is currently governed by the national laws of the
individual EU Member States, is the procedure according to which the assessment of the public health impact, therapeutic impact and the economic and
societal  impact  of  use  of  a  given  medicinal  product  in  the  national  healthcare  systems  of  the  individual  country  is  conducted.  The  outcome  of  HTA
regarding  specific  medicinal  products  will  often  influence  the  pricing  and  reimbursement  status  granted  to  these  medicinal  products  by  the  competent
authorities of individual EU Member States. On January 31, 2018, the European Commission adopted a proposal for a regulation on health technologies
assessment. The proposed regulation is intended to boost cooperation among EU Member States in assessing health technologies, including new medicinal
products,  and  providing  the  basis  for  cooperation  at  EU  level  for  joint  clinical  assessments  in  these  areas.  In  December  2021  the  HTA  Regulation  was
adopted and entered into force on 11 January 2022. It will apply from 2025.
We believe that pricing pressures at the federal and state levels in the United States, at national level in the European Union, as well as internationally, will
continue and may increase, which may make it difficult for us to sell our potential product candidates that may be approved in the future at a price
acceptable to us or any third parties with whom we may choose to collaborate. Further, it is possible that additional governmental action is taken in
response to the COVID-19 pandemic.

19

Any of our product candidates for which we obtain marketing approval could be subject to post-marketing restrictions or withdrawal from the market,
and  we  may  be  subject  to  substantial  penalties  if  we  fail  to  comply  with  regulatory  requirements  or  experience  unanticipated  problems  with  our
products following approval.

Any  of  our  product  candidates  for  which  we  obtain  marketing  approval,  as  well  as  the  manufacturing  processes,  post-approval  studies  and  measures,
labeling, advertising and promotional activities for such products, among other things, will be subject to continual requirements of and review by the EMA,
FDA and other regulatory authorities. These requirements include submissions of safety and other post-marketing information and reports, registration and
listing requirements, requirements relating to manufacturing, quality control, quality assurance and corresponding maintenance of records and documents,
requirements  regarding  the  distribution  of  samples  to  physicians  and  recordkeeping.  Even  if  marketing  approval  of  a  product  candidate  is  granted,  the
approval may be subject to limitations on the indicated uses for which the product may be marketed or to the conditions of approval, including the FDA
requirement to implement a REMS to ensure that the benefits of a drug or biological product outweigh its risks.

The  European  Commission  and  FDA  may  also  impose  requirements  for  costly  post-marketing  studies  or  clinical  trials  and  surveillance  to  monitor  the
safety or efficacy of a product, such as long-term observational studies on natural exposure. The FDA and other agencies, including the Department of
Justice, closely regulate and monitor the post-approval marketing and promotion of products to ensure that they are manufactured, marketed and distributed
only for the approved indications and in accordance with the provisions of the approved labeling. The European Commission and FDA impose stringent
restrictions  on  manufacturers’  communications  regarding  off-label  use  and  if  we  do  not  market  any  of  our  product  candidates  for  which  we  receive
marketing  approval  for  only  their  approved  indications,  we  may  be  subject  to  warnings  or  enforcement  action  for  off-label  marketing.  Violation  of  the
Federal  Food,  Drug  and  Cosmetic  Act,  or  FDCA,  and  other  statutes,  including  the  civil  False  Claims  Act,  relating  to  the  promotion  and  advertising  of
prescription drugs may lead to investigations or allegations of violations of federal and state health care fraud and abuse laws and state consumer protection
laws. Post marketing regulations in the EU and in EU Member States also require specifications regarding promotion and advertising of prescription drugs.

The  FDA,  and  national  authorities  in  the  individual  EU  Member  States  and  other  regulatory  agencies  actively  enforce  the  laws  and  regulations
prohibiting the promotion of drugs for off-label uses. If we are found to have improperly promoted off-label use, we may become subject to significant
liability.

The FDA, the national authorities in the individual EU Member States, and other regulatory agencies strictly regulate the promotional claims that may be
made  about  prescription  drug  products,  such  as  our  product  candidates,  if  approved.  In  particular,  a  product  may  not  be  promoted  for  uses  that  are  not
approved by the European Commission, FDA or such other regulatory agencies as reflected in the product’s approved labeling. However, we may share
truthful and not misleading information that is otherwise consistent with the product’s approved labeling. For example, if we receive marketing approval
for eryaspase, physicians, in their professional medical judgment, may nevertheless prescribe eryaspase to their patients in a manner that is inconsistent
with the approved label. If we are found to have promoted such off-label use, we may become subject to significant liability under the FDCA and other
statutory  authorities,  such  as  laws  prohibiting  false  claims  for  reimbursement.  The  federal  government  has  levied  large  civil  and  criminal  fines  against
companies for alleged improper promotion and has enjoined several companies from engaging in off-label promotion. The FDA has also requested that
companies  enter  into  consent  decrees  or  permanent  injunctions  under  which  specified  promotional  conduct  is  changed  or  curtailed.  If  we  cannot
successfully manage the promotion of our products, if approved, we could become subject to significant liability, which would harm our reputation and
negatively  impact  our  financial  condition.  In  addition  to  European  legislation,  each  EU  Member  State  also  enforce  specific  national  laws  regarding  the
regulation of promotional claims which may change depending of the country marketing.

Our future growth depends, in part, on our ability to penetrate foreign markets, where we would be subject to additional regulatory burdens and other
risks and uncertainties.

Our future profitability will depend, in part, on our ability to commercialize our product candidates in markets within and without the United States and the
European Union. If we commercialize our product candidates in foreign markets, we would be subject to additional risks and uncertainties, including:

•

•

•

•

•

•

•

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

the burden of complying with complex and changing foreign regulatory, tax, accounting and legal requirements, many of which vary between
countries;

different medical practices and customs in foreign countries affecting acceptance in the marketplace;

tariffs and trade barriers;

other trade protection measures, import or export licensing requirements or other restrictive actions by U.S. or foreign governments;

longer accounts receivable collection times;

longer lead times for shipping;

20

•

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

• workforce uncertainty in countries where labor unrest is common;

•

•

•

•

•

•

language barriers for technical training;

reduced protection of intellectual property rights in some foreign countries, and related prevalence of generic alternatives to therapeutics;

foreign currency exchange rate fluctuations and currency controls;

differing foreign reimbursement landscapes;

uncertain and potentially inadequate reimbursement of our products; and

the interpretation of contractual provisions governed by foreign laws in the event of a contract dispute.

Foreign  sales  of  our  products  could  also  be  adversely  affected  by  the  imposition  of  governmental  controls,  political  and  economic  instability,  trade
restrictions and changes in tariffs.

Adverse market and economic conditions may exacerbate certain risks associated with commercializing our product candidates.

Future  sales  of  our  product  candidates,  if  they  are  approved,  will  be  dependent  on  purchasing  decisions  of  and  reimbursement  from  government  health
administration  authorities,  distributors  and  other  organizations.  As  a  result  of  adverse  conditions  affecting  the  global  economy  and  credit  and  financial
markets, including disruptions due to political instability or otherwise, these organizations may defer purchases, may be unable to satisfy their purchasing
or reimbursement obligations, or may delay payment for eryaspase or any of our product candidates that are approved for commercialization in the future.
In addition, there have been concerns for the overall stability and suitability of the euro as a single currency given the economic and political challenges
facing  individual  Eurozone  countries.  Continuing  deterioration  in  the  creditworthiness  of  Eurozone  countries,  the  withdrawal  of  one  or  more  member
countries from the European Union, or the failure of the euro as a common European Union currency or an otherwise diminished value of the euro could
materially and adversely affect our future product revenue from European Union sales of our products.

3.D.5. Risks Related to the Production and Manufacturing of our Product Candidates and Future Products, if Any

Our production capacity could prove insufficient for our needs.

Our  production  capacity  may  prove  insufficient  in  the  future  to  meet  the  growth  of  our  business,  including  producing  sufficient  quantities  of  product
candidates for preclinical studies, clinical trials and, ultimately, our customers and distributors. Although we have extended our production capacity for our
current  clinical  trials  and  a  potential  commercial  launch,  if  approved,  with  the  extension  of  our  manufacturing  facility  in  Lyon,  France  and  we  have
concluded a commercial supply arrangement with Catalent (as defined below) for the supply of eryaspase in the United States, there is no guarantee that we
will or have properly estimated our required manufacturing capacities or that the third parties we rely on to provide required machinery and materials for
the  manufacturing  process  will  be  able  to  perform  on  our  proposed  timelines  or  meet  our  manufacturing  demands,  if  at  all.  Also,  if  we  must  increase
production capacity for any reason, we may need to make considerable investments that could lead to significant financing needs or require us to enter into
subcontracting agreements in order to outsource part of the production.

We may not have access to the raw materials and other components, including asparaginase and red blood cells, necessary for the manufacturing of
our product candidates.

We are dependent on third parties for the supply of various materials that are necessary to produce our product candidates for clinical trials.

With respect to eryaspase, we rely on Medac GmbH, or Medac, for the supply of asparaginase. Since we rely on a single-source supplier for asparaginase,
if our agreement with Medac GmbH were to be terminated or if this supplier is unable to meet our demands for asparaginase, we could experience delays in
our  research  or  planned  clinical  trials  or  commercialization.  We  could  be  unable  to  find  alternative  suppliers  of  acceptable  quality,  in  the  appropriate
volumes and at an acceptable cost.

With regard to the supply of red blood cells, we rely on the New York Blood Center and the American Red Cross in the United States and the French Blood
Agency  (Établissement  Français  du  Sang)  and  the  German  Red  Cross  Blood  Donor  Service  in  the  European  Union.  The  French  Blood  Agency
(Établissement Français du Sang) is the sole operator in its territory for blood transfusions and is in charge of satisfying national needs for blood products.
Although we have entered into agreements with the New York Blood Center, the American Red Cross, the French Blood Agency (Établissement Français
du Sang) and the German Red Cross Blood Donor Service related to the supply of those materials, the supply could be reduced or interrupted at any time.
In such case, we may not be able to find other suppliers of acceptable materials in appropriate quantities at an acceptable cost. If we lose key suppliers or
the supply of materials is diminished or discontinued, or in the event of a major or international crisis impacting blood banks and the practice of blood
donation, we may not be able to continue to develop, manufacture and market our product candidates or products in a timely and competitive manner.

21

In addition, these materials are subject to stringent manufacturing processes and rigorous testing. Delays in the completion and validation of facilities and
manufacturing  processes  of  these  materials  could  adversely  affect  our  ability  to  complete  trials  and  commercialize  our  products  in  a  cost-effective  and
timely manner. If we encounter difficulties in the supply of these materials, chemicals or biological products, or if we were not able to maintain our supply
agreements including the commercial supply arrangement with Catalent (as defined below), or establish new supply agreements in the future, our product
development and our business prospects could be significantly compromised.

Our manufacturing facilities are subject to significant government regulations and approvals. If we or our third-party manufacturers fail to comply
with these regulations or maintain these approvals, our business will be materially harmed.

We  currently  manufacture  our  product  candidates  for  use  in  the  European  Union  in  our  facility  in  Lyon,  France.  In  addition,  we  have  entered  into
agreements with the American Red Cross, the French Blood Agency (Établissement Français du Sang), the German Red Cross Blood Donor Service and
the  New  York  Blood  Center  to  produce  eryaspase  for  use  in  our  clinical  trials  in  the  European  Union  and  in  the  United  States  and  we  built  a  U.S.
manufacturing facility in Princeton, New Jersey (the “Princeton Facility”), which began producing eryaspase for use in our U.S clinical trials in the fourth
quarter  of  2019.  In  April  2022,  we  sold  the  lease  for  the  Princeton  Facility  and  certain  assets  and  inventory  of  materials  located  thereat  to  Catalent
Princeton, LLC (“Catalent”) pursuant to an asset purchase agreement. In connection therewith, we entered into an interim supply agreement with Catalent
under which Catalent agreed to manufacture and supply us with eryaspase for our clinical and commercial uses of eryaspase in the United States. We also
have an agreement with Medac to provide us with L-asparaginase for use in our production of eryaspase. We and our third-party manufacturers are subject
to  ongoing  regulation  and  periodic  inspection  by  the  EMA,  FDA  and  other  regulatory  bodies  to  ensure  compliance  with  current  Good  Manufacturing
Practices, or cGMP, as part of our clinical trials. Any failure to follow and document our or their adherence to such cGMP regulations or other regulatory
requirements may lead to significant delays in the availability of products for commercial sale or clinical trials, may result in the termination of or a hold on
a clinical trial, 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 European Commission, FDA, the national authorities in the individual EU Member
States, or other applicable regulatory 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 product recalls or seizing products;

•

•

imposing operating restrictions; and

seeking criminal prosecutions.

Any of the foregoing actions could be detrimental to our reputation, business, financial condition or operating results. Furthermore, our key suppliers may
not continue to be in compliance with all applicable regulatory requirements, which could result in our failure to produce our products on a timely basis and
in  the  required  quantities,  if  at  all.  In  addition,  before  any  additional  products  would  be  considered  for  marketing  approval  in  the  United  States,  the
European  Union  or  elsewhere,  our  suppliers  will  have  to  pass  an  audit  by  the  applicable  regulatory  agencies.  We  are  dependent  on  our  suppliers’
cooperation and ability to pass such audits, and the audits and any audit remediation may be costly. Failure to pass such audits by us or any of our suppliers
would affect our ability to commercialize our product candidates in the United States, the European Union or elsewhere.

Our production costs may be higher than we currently estimate.

We manufacture our product candidates according to manufacturing best practices applicable to drugs for clinical trials and to specifications approved by
the applicable regulatory authorities. If any of our products are found to be non-compliant, we would be required to manufacture the product again, which
would entail additional costs and may prevent delivery of the product to patients on time.

Other risks inherent in the production process may have the same effect, such as:

•

•

•

contamination of the controlled atmosphere area;

unusable premises and equipment;

new regulatory requirements requiring a partial and/or extended stop to the production unit to meet the requirements;

22

•

•

•

•

unavailable qualified personnel;

power failure of extended duration;

logistical error; and

rupture  in  the  cold  chain,  which  is  a  system  for  storing  and  transporting  blood  and  blood  products  within  the  correct  temperature  range  and
conditions.

In addition, a rise in direct or indirect energy rates may increase product manufacturing and logistical costs. Any of these risks, should they occur, could
disrupt our activities and compromise our financial position, results, reputation or growth.

3.D.6. Risks Related to Our Employees and Business

We may encounter difficulties in managing our growth, which could disrupt our operations.

As of December 31, 2021, we had 181 employees, and we expect to increase our number of employees and the scope of our operations. To manage our
development  and  expansion,  including  the  potential  commercialization  of  our  product  candidates  in  the  European  Union  and  the  United  States,  we  will
need  to  implement  and  improve  our  managerial,  operational  and  financial  systems,  expand  our  facilities  and  continue  to  recruit  and  train  additional
qualified personnel. Also, our management may need to divert a disproportionate amount of its attention away from its day-to-day activities and devote a
substantial amount of time to managing these development activities. Due to our limited resources, we may not be able to effectively manage the expansion
of our operations or recruit and train additional qualified personnel. This may result in weaknesses in our infrastructure, give rise to operational mistakes,
loss of business opportunities, loss of employees and reduced productivity among remaining employees. The physical expansion of our operations may
lead to significant costs and may divert financial resources from other projects, such as the development of our product candidates. If our management is
unable to effectively manage our expected development and expansion, our expenses may increase more than expected, our ability to generate or increase
our  revenue  could  be  reduced  and  we  may  not  be  able  to  implement  our  business  strategy.  Our  future  financial  performance  and  our  ability  to
commercialize  our  product  candidates,  if  approved,  and  compete  effectively  will  depend,  in  part,  on  our  ability  to  effectively  manage  the  future
development and expansion of our company.

We depend on qualified management personnel and our business could be harmed if we lose key personnel and cannot attract new personnel.

Our success depends to a significant degree upon the technical and management skills of our senior management team. The loss of the services of any of
these  individuals  could  have  a  material  adverse  effect  on  our  ability  to  achieve  our  corporate  objectives  and  successfully  execute  our  business  plan.
Although  we  have  implemented  an  executive  compensation  policy  that  includes  variable  compensation  based  on  performance  as  well  as  share-based
compensation plans for the benefit of our key employees, we cannot guarantee that this policy will be sufficient to retain these key employees. Our success
also  will  depend  upon  our  ability  to  attract  and  retain  additional  qualified  management,  marketing,  technical,  and  sales  executives  and  personnel.  We
compete for key personnel against numerous companies, including larger, more established companies with significantly greater financial resources than
we  possess.  There  can  be  no  assurance  that  we  will  be  successful  in  attracting  or  retaining  such  personnel,  and  the  failure  to  do  so,  could  harm  our
operations and our growth prospects.

Our failure to maintain certain tax benefits applicable to French biopharmaceutical companies may adversely affect our results of operations, our cash
flows and our financial condition.

As a French biopharmaceutical company, we have benefited from certain tax advantages, including, for example, the CIR, which is a French tax credit
aimed at stimulating research and development. The CIR can be offset against French corporate income tax due and the portion in excess, if any, may be
refunded. The CIR is calculated based on our claimed amount of eligible research and development expenditures in France and amounted to €3.9 million,
€3.4 million and €3.7 million for the years ended December 31, 2019, 2020 and 2021, respectively. The French tax authorities, with the assistance of the
Research and Higher Education Ministry, may audit each research and development program in respect of which a CIR benefit has been claimed and assess
whether such program qualifies in its view for the CIR benefit. The French tax authorities may challenge our eligibility for, or our calculation of, certain tax
reductions or deductions in respect of our research and development activities. Should the French tax authorities be successful, the CIR representing the
majority of the our operating revenues (92% of revenues for the year ended December 31, 2020 and more than 90% for the years ended December 31, 2019
and December 31, 2021), our credits may be reduced, which would have a negative impact on our results of operations and future cash flows. We believe,
due to the nature of our business operations, that we will continue to be eligible to receive the CIR tax credit. However, if the French Parliament decides to
eliminate,  or  to  reduce  the  scope  or  the  rate  of,  the  CIR  benefit,  either  of  which  it  could  decide  to  do  at  any  time,  our  results  of  operations  could  be
adversely affected.

23

The COVID-19 coronavirus could adversely impact our business, including our clinical trials.

In December 2019, a novel strain of coronavirus, COVID-19, was reported to have surfaced in Wuhan, China. Since then, the COVID-19 coronavirus has
spread globally, including to France, the United States and many of the countries in which we have planned or ongoing clinical trials. If the COVID-19
coronavirus continues to spread in France and the United States, we may experience disruptions that could severely impact our business and clinical trials,
including:

•

•

•

•

•

delays or difficulties in enrolling patients in our clinical trials;

delays or difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical site staff;

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

interruption of key clinical trial activities, such as clinical trial site monitoring, due to limitations on travel imposed or recommended by federal
or state governments, employers and others; and

limitations  in  employee  resources  that  would  otherwise  be  focused  on  the  conduct  of  our  clinical  trials,  including  because  of  sickness  of
employees or their families or the desire of employees to avoid contact with large groups of people.

We did not suffer any delay in other studies that would be related to the economic and health effects of the COVID-19 pandemic.

For our clinical trials that are being conducted in countries which are experiencing heightened impact from the COVID-19 coronavirus, in addition to the
risks listed above, we may also experience the following adverse impacts:

•

•

•

•

•

•

delays in receiving approval from local regulatory authorities to initiate our planned clinical trials;

delays in clinical sites receiving the supplies and materials needed to conduct our clinical trials;

interruption in global shipping that may affect the transport of clinical trial materials, such as investigational drug product and comparator drugs
used in our clinical trials;

changes in local regulations as part of a response to the COVID-19 coronavirus outbreak which may require us to change the ways in which our
clinical trials are conducted, which may result in unexpected costs, or to discontinue the clinical trials altogether;

delays  in  necessary  interactions  with  local  regulators,  ethics  committees  and  other  important  agencies  and  contractors  due  to  limitations  in
employee resources or forced furlough of government employees; and

refusal of the EMA or the FDA to accept data from clinical trials in these affected geographies.

The global outbreak of the COVID-19 coronavirus and the apparition of new variants such as Omicron continues to rapidly evolve. The extent to which the
COVID-19 coronavirus may impact our business and clinical trials will depend on future developments, which are highly uncertain and cannot be predicted
with confidence, such as the ultimate geographic spread of the disease, the duration of the outbreak, travel restrictions and social distancing in the European
Union, the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the European Union, the
United States and other countries to contain and treat the disease such as the lockdown measures put in place in most countries. Further, the adverse effect
on the financial markets, on the market price of our ADSs and/or ordinary shares, is unknown. To date, the global economy remains heavily impacted by
the outbreak of the COVID-19 coronavirus. We believe that the recently emerged variants of the Covid-19 coronavirus are not likely to modify the risks as
described above.

Our business may become subject to economic, political, regulatory and other risks associated with international operations.

We are a company based in France with international operations, including in the United States. A significant portion of our suppliers and collaborative and
clinical trial relationships are located outside the United States. Accordingly, our future results could be harmed by a variety of factors, including:

•

•

•

•

•

•

•

•

economic weakness, including inflation, or political instability in particular non-U.S. economies and markets;

differing regulatory requirements for drug approvals in non-U.S. countries;

differing jurisdictions could present different issues for securing, maintaining or obtaining freedom to operate in such jurisdictions;

potentially reduced protection for intellectual property rights;

difficulties in compliance with non-U.S. laws and regulations;

changes in non-U.S. regulations and customs, tariffs and trade barriers;

changes in non-U.S. currency exchange rates of the euro and currency controls;

changes in a specific country's or region's political or economic environment, including the withdrawal of the United Kingdom from the EU;

24

•

•

•

•

trade protection measures, import or export licensing requirements or other restrictive actions by U.S. or non-U.S. governments;

differing reimbursement regimes and price controls in certain non-U.S. markets;

negative consequences from changes in tax laws;

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

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

•

•

•

difficulties associated with staffing and managing international operations, including differing labor relations;

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

business  interruptions  resulting  from  geo-political  actions,  including  war  and  terrorism,  or  natural  disasters  including  earthquakes,  typhoons,
floods and fires, or public health emergencies, such as the novel COVID-19 coronavirus.

In late February 2022, Russian military forces launched a significant military action against Ukraine (the “Russia-Ukraine crisis”), and sustained conflict
and disruption in the region is likely. The impact to Ukraine, as well as actions taken by other countries, including new and stricter sanctions by Canada, the
United  Kingdom,  the  European  Union,  the  United  States  and  other  countries  and  organizations  against  officials,  individuals,  regions,  and  industries  in
Russia, Ukraine and Belarus, and each country’s potential response to such sanctions, tensions, and military actions could damage or disrupt international
commerce and the global economy, and could have a material adverse effect on our business and results of operations.

While our business and operations are currently not impacted, it is not possible to predict the broader or longer-term consequences of the Russia-Ukraine
crisis. Consequences of the Russia-Ukraine crisis could include further sanctions, embargoes, regional instability, geopolitical shifts and adverse effects on
macroeconomic conditions, security conditions, currency exchange rates and financial markets. There can be no assurance that the Russia-Ukraine crisis,
including any resulting sanctions, export controls or other restrictive actions, will not have a material adverse impact on our future operations and results.

Our business may be exposed to foreign exchange risks.

Owing to the international scope of our operations, fluctuations in exchange rates, particularly between the euro and the U.S. dollar, may adversely affect
us. Although we are based in the France, we source research and development, manufacturing, consulting and other services from the United States as well
as other countries outside the European Union. We incur some of our expenses, and may in the future derive revenues, in currencies other than the euro.

We use the euro as our functional currency for our financial communications. However, a significant portion of our expenses, financial assets and liabilities
are  denominated  in  U.S  dollars  and  are  exposed  to  changes  in  foreign  currency  exchange  rates.  We  also  entered  into  a  license  agreement  with  SQZ
Biotechnologies  in  2019  and  any  potential  revenues  pursuant  to  this  agreement  will  be  made  in  U.S.  dollars.  We  do  not  currently  engage  in  hedging
transactions or the use of forward contracts but may in the future in order to minimize the impact of uncertainty in future exchange rates on cash flows. A
deterioration of the U.S dollar of the Euro could reduce our cash and cash equivalents. Refer to "Item 11. Quantitative and Qualitative Disclosures About
Market Risk" for more information.

As we advance our clinical development in the United States and potentially commercialize our product candidates in that market, we expect to face greater
exposure to exchange rate risk. We cannot predict the impact of foreign currency fluctuations, and foreign currency fluctuations in the future may adversely
affect our financial condition, results of operations and cash flows. Therefore, fluctuations in the exchange rate between the euro and the U.S. dollar will
also affect, among other matters, the value of our ordinary shares and ADSs.

We  may  use  hazardous  chemicals  and  biological  materials  in  our  business.  Any  claims  relating  to  improper  handling,  storage  or  disposal  of  these
materials could be time-consuming and costly.

Our  research  and  development  processes  involve  the  controlled  use  of  hazardous  materials,  including  chemicals  and  biological  materials.  We  cannot
eliminate the risk of accidental contamination or discharge and any resultant injury from these materials. We may be sued for any injury or contamination
that results from our use or the use by third parties of these materials, and our liability may exceed any insurance coverage and our total assets. French and
U.S.  federal,  state,  local  or  foreign  laws  and  regulations  govern  the  use,  manufacture,  storage,  handling  and  disposal  of  these  hazardous  materials  and
specified waste products, as well as the discharge of pollutants into the environment and human health and safety matters. Compliance with environmental
laws and regulations may be expensive and may impair our research and development efforts. If we fail to comply with these requirements, we could incur
substantial  costs,  including  civil  or  criminal  fines  and  penalties,  clean-up  costs  or  capital  expenditures  for  control  equipment  or  operational  changes
necessary  to  achieve  and  maintain  compliance.  In  addition,  we  cannot  predict  the  impact  on  our  business  of  new  or  amended  environmental  laws  or
regulations or any changes in the way existing and future laws and regulations are interpreted and enforced.

25

Product  liability  and  other  lawsuits  could  divert  our  resources,  result  in  substantial  liabilities  and  reduce  the  commercial  potential  of  our  product
candidates.

Although  we  comply  with  cGMP,  and  Good  Clinical  Practices,  or  GCPs,  the  risk  that  we  may  be  sued  on  product  liability  claims  is  inherent  in  the
development and commercialization of biopharmaceutical products. Side effects of, or manufacturing defects in, products that we develop could result in
the deterioration of a patient’s condition, injury or even death. Our liability could be sought after by patients participating in the clinical trials in the context
of  the  development  of  the  therapeutic  products  tested  and  unexpected  side  effects  resulting  from  the  administration  of  these  products.  For  example,  we
reported  adverse  events  in  our  Phase  2b  clinical  trial  of  second-line  treatment  of  patients  with  metastatic  pancreatic  cancer  compared  to  treatment  with
chemotherapy alone. The percentage of patients with at least one adverse event reported as grade 3 or 4 (i.e., most commonly, increased gamma glutamyl
transferase, neutropenia, deterioration of general health and anemia) amounted to 79% in the eryaspase treatment arm, versus 86% in the control arm, and
the  percentage  of  patients  with  at  least  one  reported  severe  adverse  event  (i.e.,  most  commonly,  deterioration  in  general  health  and  gastrointestinal
hemorrhage) amounted to 45% in the eryaspase treatment arm versus 50% in the control arm. Once a product is approved for sale and commercialized, the
likelihood  of  product  liability  lawsuits  increases.  Criminal  or  civil  proceedings  might  be  filed  against  us  by  patients,  regulatory  authorities,
biopharmaceutical  companies  and  any  other  third  party  using  or  marketing  our  products.  These  actions  could  include  claims  resulting  from  acts  by  our
partners,  licensees  and  subcontractors,  over  which  we  have  little  or  no  control.  These  lawsuits  may  divert  our  management  from  pursuing  our  business
strategy and may be costly to defend. In addition, if we are held liable in any of these lawsuits, we may incur substantial liabilities and may be forced to
limit or forgo further commercialization of the affected products.

We maintain product liability insurance coverage for our clinical trials at levels which we believe are appropriate for our clinical trials. Nevertheless, our
insurance coverage may be insufficient to reimburse us for any expenses or losses we may suffer. In addition, in the future, we may not be able to obtain or
maintain sufficient insurance coverage at an acceptable cost or to otherwise protect against potential product or other legal or administrative liability claims
by us or our collaborators, licensees or subcontractors, which could prevent or inhibit the commercial production and sale of any of our product candidates
that  receive  regulatory  approval.  Product  liability  claims  could  also  harm  our  reputation,  which  may  adversely  affect  our  ability  to  commercialize  our
products successfully.

Our  internal  computer  systems,  or  those  of  our  third-party  contractors  or  consultants,  may  fail  or  suffer  security  breaches,  which  could  result  in  a
material disruption of our product development programs.

Despite the implementation of security measures, our internal computer systems and those of our third-party contractors and consultants are vulnerable to
damage  from  computer  viruses,  unauthorized  access,  natural  disasters,  terrorism,  war  and  telecommunication  and  electrical  failures.  While  we  do  not
believe that we have experienced any such system failure, accident or security breach to date, including cybersecurity incidents, if such an event were to
occur and cause interruptions in our operations, it could result in a material disruption of our programs. For example, the loss of clinical trial data for our
product candidates could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the lost data. To the
extent that any disruption or security breach results in a loss of or damage to our data or applications or other data or applications relating to our technology
or product candidates, or inappropriate disclosure of confidential or proprietary information, we could incur liabilities and the further development of our
product  candidates  could  be  delayed.  As  these  threats  continue  to  evolve,  particularly  around  cybersecurity,  we  may  be  required  to  expend  significant
resources  to  enhance  our  control  environment,  processes,  practices  and  other  protective  measures.  Despite  these  efforts,  such  events  could  materially
adversely affect our business, financial condition or results of operations.

We may acquire businesses or products, or form strategic alliances, in the future, and we may not realize the benefits of such acquisitions.

Our current growth strategy could involve plans to acquire companies or technologies facilitating or enabling us to access to new medicines, new research
projects, or new geographical areas, or enabling us to express synergies with our existing operations. If such acquisitions were to become necessary in the
future, we may not be able to identify appropriate targets or make acquisitions under satisfactory conditions, in particular, satisfactory price conditions. In
addition, we may be unable to obtain the financing for these acquisitions on favorable terms, which could require us to finance these acquisitions using our
existing cash resources that could have been allocated to other purposes. If we acquire businesses with promising markets or technologies, we may not be
able to realize the benefit of acquiring such businesses if we are unable to successfully integrate them with our existing operations and company culture.
We may encounter numerous difficulties in developing, manufacturing and marketing any new products resulting from a strategic alliance or acquisition
that delay or prevent us from realizing their expected benefits or enhancing our business. We cannot assure you that, following any such acquisition, we
will achieve the expected synergies to justify the transaction.

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

The collection and use of personal data in the European Union is governed by the provisions of the General Data Protection Regulation ((EU) 2016/679), or
GDPR. This legislation imposes requirements relating to having legal bases for processing personal data relating to identifiable individuals and securing
transfers  of  such  data  outside  the  European  Economic  Area  including  to  the  United  States,  providing  information  to  those  individuals  regarding  the
processing of their personal data, keeping personal data secure, having data processing agreements with third parties who process personal data, responding
to  individuals’  requests  to  exercise  their  rights  in  respect  of  their  personal  data,  reporting  security  breaches  involving  personal  data  to  the  competent
national data protection authority and affected individuals, conducting record-keeping and,where applicable, appointing data protection officers, conducting
data protection impact assessments. The GDPR imposes additional responsibilities and liabilities in relation to personal data that we process and we may be
required to put in place additional mechanisms ensuring compliance with the new data protection rules. The GDPR applies across the EEA and, by virtue
of the UK GDPR in the United Kingdom, in a broadly uniform manner. However, the GDPR provides that EEA member states can make their own further
laws and regulations to introduce specific requirements related to the processing of ‘special categories of personal data,’ including personal data related to
health, biometric data used for unique identification purposes and genetic information; as well as personal data related to criminal offences or convictions.
In the United Kingdom, the United Kingdom Data Protection Act 2018 complements the UK GDPR in this regard. This fact may lead to greater divergence
on the law that applies to the processing of such data types across the EEA and/or United Kingdom, compliance with which, as and where applicable, may
increase our costs and could increase our overall compliance risk. Such country-specific regulations could also limit our ability to collect, use and share
data in the context of our EEA and/or United Kingdom establishments (regardless of where any processing in question occurs), and/or could cause our
compliance costs to increase, ultimately having an adverse impact on our business, and harming our business and financial condition. Failure to comply
with the requirements of the GDPR and related national data protection laws of the EEA member states may result in substantial fines, other administrative
penalties  and  civil  claims  being  brought  against  us,  which  could  have  a  material  adverse  effect  on  our  business,  results  of  operations  and  financial
condition. Moreover, in some EEA member countries, including France, the hosting of personal health data must be carried out by specifically certified
hosting service providers. The absence or suspension of the appropriate certification of such hosting service provider may adversely affect our business, or
even lead to penalties related to breach of security of personal data.

We are subject to U.S. and certain foreign export and import controls, sanctions, embargoes, anti-corruption laws, and anti-money laundering laws and
regulations. Compliance with these legal standards could impair our ability to compete in domestic and international markets. We can face criminal
liability and other serious consequences for violations, which can harm our business.

We are subject to export control and import laws and regulations, including the U.S. Export Administration Regulations, U.S. Customs regulations, various
economic  and  trade  sanctions  regulations  administered  by  the  U.S.  Treasury  Department’s  Office  of  Foreign  Assets  Controls,  the  U.S.  Foreign  Corrupt
Practices Act of 1977, as amended, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act, and other
state and national anti-bribery and anti-money laundering laws in the countries in which we conduct activities. Anti-corruption laws are interpreted broadly
and prohibit companies and their employees, agents, contractors, and other collaborators from authorizing, promising, offering, or providing, directly or
indirectly, improper payments or anything else of value to recipients in the public or private sector. We may engage third parties to sell our products sell our
products  outside  the  United  States,  to  conduct  clinical  trials,  and/or  to  obtain  necessary  permits,  licenses,  patent  registrations,  and  other  regulatory
approvals. We have direct or indirect interactions with officials and employees of government agencies or government-affiliated hospitals, universities, and
other organizations. We can be held liable for the corrupt or other illegal activities of our employees, agents, contractors, and other collaborators, even if we
do not explicitly authorize or have actual knowledge of such activities. Any violations of the laws and regulations described above may result in substantial
civil and criminal fines and penalties, imprisonment, the loss of export or import privileges, debarment, tax reassessments, breach of contract and fraud
litigation, reputational harm, and other consequences.

3.D.7. Risks Related to Other Legal Compliance Matters

We are subject to anti-bribery, anti-kickback, fraud and abuse and other healthcare laws and regulations which may require substantial compliance
efforts and could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings,
among other penalties.

Healthcare providers, physicians and others will play a primary role in the recommendation and prescription of our products, if approved. Our business
operations  in  the  United  States  and  our  arrangements  with  clinical  investigators,  healthcare  providers,  consultants,  third  party  payors  and  patients  may
expose us to broadly applicable federal and state anti-bribery fraud and abuse and other healthcare laws. These laws may impact, among other things, our
research, proposed sales, marketing and education programs of

27

our product candidates that obtain marketing approval. Restrictions under applicable U.S. federal, state and foreign healthcare laws and regulations include,
but are not limited to, the following:

•

•

•

the U.S. federal Anti-Kickback Statute, which prohibits, among other things, persons or entities from knowingly and willfully soliciting, offering,
receiving or providing remuneration, including any kickback, bribe or rebate, directly or indirectly, in cash or in kind, to induce or reward, or in
return for, either the referral of an individual for, or the purchase or lease, order or recommendation of, any item, good, facility or service, for
which payment may be made under federal healthcare programs such as Medicare and Medicaid;

the U.S. federal civil and criminal false claims laws, including the civil False Claims Act, which can be enforced by individuals, on behalf of the
government, through civil whistleblower or qui tam actions, and civil monetary penalties laws prohibits individuals or entities from, among other
things, knowingly presenting, or causing to be presented, claims for payment that are false or fraudulent or making a false statement to avoid,
decrease, or conceal an obligation to pay money to the federal government;

the  U.S.  federal  Health  Insurance  Portability  and  Accountability  Act  of  1996,  or  HIPAA,  which  created  additional  federal,  civil  and  criminal
statutes that impose criminal and civil liability for, among other things, executing or attempting to execute a scheme to defraud any healthcare
benefit program or knowingly and willingly falsifying, concealing or covering up a material fact or making false statements relating to healthcare
matters;

• HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act,  or  HITECH,  and  their  implementing
regulations, which impose requirements on certain healthcare providers, health plans and healthcare clearinghouses, known as “covered entities,”
and persons or entities that perform functions or activities that involve individually identifiable health information on behalf of a covered entity,
known as “business associates,” including mandatory contractual terms as well as their covered subcontractors, with respect to safeguarding the
privacy, security and transmission of individually identifiable health information;

• U.S.  federal  transparency  requirements  under  the  Physician  Payments  Sunshine  Act,  enacted  as  part  of  the  ACA,  that  require  applicable
manufacturers  of  covered  drugs,  devices,  biologics  and  medical  supplies  for  which  payment  is  available  under  Medicare,  Medicaid,  or  the
Children’s  Health  Insurance  Program,  with  specific  exceptions,  to  track  and  annually  report  to  the  CMS  payments  and  other  transfers  of  value
provided to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors), other healthcare professionals (such as
physicians assistances and nurse practitioners) and teaching hospitals, as well as certain ownership and investment interests held by physicians or
their immediate family members;

•

analogous  state  or  foreign  laws  and  regulations,  such  as  state  anti-kickback  and  false  claims  laws,  which  may  apply  to  items  or  services
reimbursed  by  any  third-party  payor,  including  commercial  insurers,  state  marketing  and/or  transparency  laws  applicable  to  manufacturers  that
may be broader in scope than the federal requirements, state laws that require biopharmaceutical companies to comply with the biopharmaceutical
industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government, state laws that require
drug manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers, marketing
expenditures, or drug pricing, state and local laws that require the registration of pharmaceutical sales representatives, and state laws governing the
privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and may not have
the same effect as HIPAA, thus complicating compliance efforts;

• GDPR, the local EU data protection laws, and other ex-U.S. protections;

•

•

the  French  “transparency”  provisions,  or  “French  Sunshine  Act”  (Articles  L.  1453-1  and  D.  1453-1  and  seq.  PHC),  which  contains  provisions
regarding  transparency  of  fees  received  by  some  healthcare  professionals  or  social  media  influencers  from  industries,  such  as  companies
manufacturing  or  marketing  healthcare  products  (medicinal  products,  medical  devices,  etc.)  or  services  related  to  these  products  in  France.
According  to  the  provisions,  these  companies  shall  publicly  disclose  (on  a  specific  public  website  available  at  www.entreprises-
transparence.sante.gouv.fr) the advantages and fees paid to healthcare professionals or social media influencers amounting to €10 or above, as well
as the agreements concluded with the latter, along with detailed information about each agreement (the precise subject matter of the agreement, the
date of signature of the agreement, its end date, the total amount paid to the healthcare professional or social media influencers, etc.); and

the  French  “anti-gift”  provisions  (Articles  L.1453-3  to  L.1453-12  PHC),  setting  out  a  general  prohibition  of  payments  and  rewards  from
industries,  i.e.  companies  manufacturing  or  marketing  health  products,  to,  but  not  only,  healthcare  professionals,  with  limited  exceptions  and
strictly defines the conditions under which such payments or awards are lawful, notably the authorization of the Conseil National de l'Ordre des
Médecins  (CNOM)  if  the  financial  counterpart  is  higher  than  a  certain  amount,  this  limit  being  different  according  to  the  nature  of  the  benefit
concerned.

Ensuring that our business arrangements with third parties comply with applicable healthcare laws and regulations will likely be costly. It is possible that
governmental  authorities  will  conclude  that  our  business  practices  do  not  comply  with  current  or  future  statutes,  regulations  or  case  law  involving
applicable  fraud  and  abuse  or  other  healthcare  laws  and  regulations.  If  our  operations  were  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

28

significant  civil,  criminal  and  administrative  penalties,  damages,  fines,  disgorgement,  imprisonment,  possible  exclusion  from  government  funded
healthcare  programs,  such  as  Medicare  and  Medicaid,  additional  reporting  requirements  and  oversight  if  we  become  subject  to  a  corporate  integrity
agreement or similar agreement to resolve allegations of non-compliance with these laws, contractual damages, reputational harm, diminished profits and
future earnings, and curtailment of our operations, any of which could substantially disrupt our operations. If the physicians or other providers or entities
with  whom  we  expect  to  do  business  are  found  not  to  be  in  compliance  with  applicable  laws,  they  may  be  subject  to  significant  criminal,  civil  or
administrative sanctions, including exclusions from government funded healthcare programs.

If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could
have a material adverse effect on the success of our business.

We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use,
storage, treatment and disposal of hazardous materials and wastes. Our research and development activities involve the use of biological and hazardous
materials  and  produce  hazardous  waste  products.  We  generally  contract  with  third  parties  for  the  disposal  of  these  materials  and  wastes.  We  cannot
eliminate  the  risk  of  contamination  or  injury  from  these  materials,  which  could  cause  an  interruption  of  our  commercialization  efforts,  research  and
development  efforts  and  business  operations,  environmental  damage  resulting  in  costly  clean-up  and  liabilities  under  applicable  laws  and  regulations
governing the use, storage, handling and disposal of these materials and specified waste products. Although we believe that the safety procedures utilized
by  our  third-party  manufacturers  for  handling  and  disposing  of  these  materials  generally  comply  with  the  standards  prescribed  by  these  laws  and
regulations, we cannot guarantee that this is the case or eliminate the risk of accidental contamination or injury from these materials. In such an event, we
may be held liable for any resulting damages and such liability could exceed our resources and state or federal or other applicable authorities may curtail
our use of certain materials and/or interrupt our business operations. Furthermore, environmental laws and regulations are complex, change frequently and
have tended to become more stringent. We cannot predict the impact of such changes and cannot be certain of our future compliance. In addition, we may
incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. These current or future laws and
regulations may impair our research, development or production efforts. Failure to comply with these laws and regulations also may result in substantial
fines, penalties or other sanctions.

Although we maintain professional liability insurance which cover for costs and expenses we may incur due to environmental liability that may be asserted
against us or due to injuries to our employees resulting from the use of hazardous materials, may not provide adequate coverage against potential liabilities.

Our  employees  may  engage  in  misconduct  or  other  improper  activities,  including  violating  applicable  regulatory  standards  and  requirements  or
engaging in insider trading, which could significantly harm our business.

We  are  exposed  to  the  risk  of  employee  fraud  or  other  misconduct.  Misconduct  by  employees  could  include  intentional  failures  to  comply  with  legal
requirements or the requirements of CMS, European Commission, EMA, FDA and other government regulators, provide accurate information to applicable
government  authorities,  comply  with  fraud  and  abuse  and  other  healthcare  laws  and  regulations  in  the  United  States  and  abroad,  report  financial
information or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry
are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and
regulations restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other
business arrangements. Employee misconduct could also involve the improper use of, including trading on, information obtained in the course of clinical
trials, which could result in regulatory sanctions and serious harm to our reputation. We have adopted a Code of Business Conduct and Ethics, but it is not
always possible to identify and deter employee misconduct, and the precautions we take to detect and prevent this activity may be ineffective in controlling
unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply
with these laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those
actions could have a significant impact on our business, including the imposition of significant civil, criminal and administrative penalties, damages, fines,
disgorgement,  imprisonment,  possible  exclusion  from  government  funded  healthcare  programs,  such  as  Medicare  and  Medicaid,  additional  reporting
requirements  and  oversight  if  we  become  subject  to  a  corporate  integrity  agreement  or  similar  agreement  to  resolve  allegations  of  non-compliance,
contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations.

Changes in European Union regulations may limit our ability to attract and obtain additional financing sources outside France.

As a result of the implementation of Regulation (EU) 2019/452 of the European Parliament and of the Council of March 19, 2019 establishing a framework
for  the  screening  of  foreign  direct  investments  into  the  European  Union,  the  list  of  sectors  of  activity  which  are  subject  to  a  control  by  the  French
authorities has been extended to cover foreign investments in additional economic sectors. Prior authorization of the Minister of Economy is required for
investments  in:  (i)  businesses  participating,  even  occasionally,  under  the  exercise  of  French  public  authority,  (ii)  businesses  that  would  be  liable  to
negatively impact public order, public security or the

29

national defense interest, as well as (iii) business focused on research, production or trade of arms, ammunition, gunpowder and explosive substances.

A foreign direct investment will be subject to authorization where there is an (i) acquisition of control, under article L.233-3 of the French Commercial
Code, of an entity subject to French law, (ii) where a party acquires all or part of a branch of activity of an entity subject to French law, (iii) or where a
party crosses directly or indirectly, and acting alone or in concert, the 25% voting rights threshold of an entity subject to French law.

The French government has adapted the foreign investment control procedure in France within the context of the ongoing COVID-19 pandemic in two
ways: (i) the inclusion, by a Ministerial order (arrêté) of April 27, 2020, of biotechnologies in the list of critical technologies and (ii) the addition, by a
Decree (décret) of July 22, 2020 as amended by Decree n°2020-1729 of December 28, 2020, of the threshold of 10% of voting rights of a company subject
to French law whose securities are listed on a stock exchange as triggering the control procedure.

The  Decree  of  July  22,  2020,  as  extended  by  the  decree  n°  2021-1758  of  December  22,  2021,  currently  provides  that  this  new  10%  threshold  will  be
effective until December 31, 2022 and a fast-track review procedure for foreign investments exceeding this threshold.

If an investment in the company subject to prior authorization is realized without this authorization having been granted, the Minister will be able to order
the investor, subject to a fine for non-performance, to: (i) file an authorization application, (ii) restore the previous situation, or (iii) amend the investment
and, if he considers that the conditions for the authorization have not been met, the Minister may also revoke the authorization or order the investor, subject
to a fine for non-performance, to comply with the authorization. In both cases, he may also take provisional measures.

Furthermore, an investor who has carried out a transaction without prior authorization or has not complied with the orders or measures set by the French
Minister of Economy will be liable to a fine of up to the greater of the following amounts: (i) double the amount of the irregular investment, (ii) 10% of the
turnover (excluding taxes) of the company, (iii) five million euros for legal entities, and (iv) one million euros for individuals.

Inclusion of biotechnologies in the list of critical technologies subject to foreign investment control procedure could discourage foreign investment in the
Company's  securities,  thereby  limiting  access  to  foreign  sources  of  financing.  If  interested  investors  do  not  or  cannot  obtain  such  authorization,  their
investment could be cancelled and be subject to additional fees and/or monetary penalties.

Future changes to tax laws could materially adversely affect our company and reduce net returns to our shareholders.

Our tax treatment is subject to the enactment of, or changes in, tax laws, regulations and treaties, or the interpretation thereof, tax policy initiatives and
reforms under consideration and the practices of tax authorities in jurisdictions in which we operate, including those related to proposals made by the Biden
administration,  the  Organization  for  Economic  Co-Operation  and  Development’s  Base  Erosion  and  Profit  Shifting  Project,  the  European  Commission’s
state aid investigations and other initiatives. Such changes may include (but are not limited to) changes in corporate tax rates, the taxation of operating
income, investment income, dividends received or (in the specific context of withholding tax) dividends paid, including foreign earnings, the realization of
net deferred tax assets relating to our operations, and the deductibility of expenses. We are unable to predict what tax reform may be proposed or enacted in
the future or what effect such changes would have on our business, but such changes, to the extent they are brought into tax laws, regulations, policies or
practices, could affect our financial position, including the value of our deferred tax assets, and overall or effective tax rates in the future in countries where
we have operations, result in significant one-time charges, reduce post-tax returns to our shareholders, and increase the complexity, burden and cost of tax
compliance.

Tax  authorities  may  disagree  with  our  positions  and  conclusions  regarding  certain  tax  positions,  resulting  in  unanticipated  costs,  taxes  or  non-
realization of expected benefits.

A tax authority may disagree with tax positions that we have taken, which could result in increased tax liabilities. For example, the U.S. Internal Revenue
Service  or  another  tax  authority  could  challenge  our  allocation  of  income  by  tax  jurisdiction  and  the  amounts  paid  between  our  affiliated  companies
pursuant  to  our  intercompany  arrangements  and  transfer  pricing  policies,  including  amounts  paid  with  respect  to  our  intellectual  property  development.
Similarly,  a  tax  authority  could  assert  that  we  are  subject  to  tax  in  a  jurisdiction  where  we  believe  we  have  not  established  a  taxable  connection,  often
referred to as a “permanent establishment” under international tax treaties, and such an assertion, if successful, could increase our expected tax liability in
one or more jurisdictions. A tax authority may take the position that material income tax liabilities, interest and penalties are payable by us, in which case,
we expect that we might contest such assessment. Contesting such an assessment may be lengthy and costly and if we were unsuccessful in disputing the
assessment, the implications could increase our anticipated effective tax rate, where applicable.

3.D.8. Risks Related to Intellectual Property

Our ability to compete may decline if we do not adequately protect our proprietary rights.

Our commercial success depends on obtaining and maintaining proprietary rights to our product candidates and defending these rights against third-party
challenges.  We  will  only  be  able  to  protect  our  product  candidates  and  their  uses  from  unauthorized  use  by  third  parties  to  the  extent  that  valid  and
enforceable patents, or effectively protected trade secrets, cover them. Our ability to obtain patent protection for our product candidates is uncertain due to
a number of factors, including:

• we or our licensors may not have been the first to make the inventions covered by pending patent applications or issued patents;

• we or our licensors may not have been the first to file patent applications for our product candidates or the compositions we developed or for

their uses;

•

•

•

others may independently develop identical, similar or alternative products or compositions and uses thereof;

our or our licensors’ disclosures in patent applications may not be sufficient to meet the statutory requirements for patentability;

any or all of our or our licensors’ pending patent applications may not result in issued patents;

• we or our licensors may not seek or obtain patent protection in countries that may eventually provide us a significant business opportunity;

•

•

•

•

any patents issued to us or our licensors may not provide a basis for commercially viable products, may not provide any competitive advantages,
or may be successfully challenged by third parties;

our or our licensors’ compositions and methods may not be patentable;

others may design around our patent claims to produce competitive products which fall outside of the scope of our patents;

or others may identify prior art or other bases which could invalidate our or our licensors’ patents.

Even if we have or obtain patents covering our product candidates or compositions, we may still be barred from making, using and selling our product
candidates  or  technologies  because  of  the  patent  rights  of  others.  Others  may  have  filed,  and  in  the  future,  may  file,  patent  applications  covering
compositions  or  products  that  are  similar  or  identical  to  ours.  There  are  many  issued  U.S.  and  foreign  patents  relating  to  chemical  compounds  and
therapeutic products, and some of these relate to compounds we intend to commercialize. Numerous U.S. and foreign issued patents and pending patent
applications owned by others exist in the cancer treatment field in which we are developing products. These could materially affect our ability to develop
our  product  candidates  or  sell  our  products  if  approved.  Because  patent  applications  can  take  many  years  to  issue,  there  may  be  currently  pending
applications unknown to us that may later result in issued patents that our product candidates or compositions may infringe. These patent applications may
have priority over patent applications filed by us.

Obtaining  and  maintaining  a  patent  portfolio  entails  significant  expense  and  resources.  Part  of  the  expense  includes  periodic  maintenance  fees,  renewal
fees, annuity fees, various other governmental fees on patents and/or applications due in several stages over the lifetime of patents and/or applications, as
well as the cost associated with complying with numerous procedural provisions during the patent application process. We may not choose to pursue or
maintain  protection  for  particular  inventions.  In  addition,  there  are  situations  in  which  failure  to  make  certain  payments  or  noncompliance  with  certain
requirements in the patent process can result in abandonment or lapse of a patent or patent application, resulting in partial or complete loss of patent rights
in  the  relevant  jurisdiction.  If  we  choose  to  forgo  patent  protection  or  allow  a  patent  application  or  patent  to  lapse  purposefully  or  inadvertently,  our
competitive position could suffer.

Legal actions to enforce our patent rights can be expensive and may involve the diversion of significant management time. In addition, these legal actions
could be unsuccessful and could also result in the invalidation of our patents or a finding that they are unenforceable. We may or may not choose to pursue
litigation  or  other  actions  against  those  that  have  infringed  on  our  patents,  or  used  them  without  authorization,  due  to  the  associated  expense  and  time
commitment of monitoring these activities. If we fail to protect or to enforce our intellectual property rights successfully, our competitive position could
suffer, which could harm our results of operations.

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

If we initiate legal proceedings against a third party to enforce a patent covering our product candidate or technology, the defendant could counterclaim that
the  patent  covering  our  product  candidate  or  technology  is  invalid  or  unenforceable.  In  patent  litigation  in  the  United  States,  defendant  counterclaims
alleging  invalidity  and  unenforceability  are  commonplace.  Grounds  for  a  validity  challenge  include  alleged  failures  to  meet  any  of  several  statutory
requirements,  including  lack  of  novelty,  obviousness  or  non-enablement.  Grounds  for  unenforceability  assertions  include  allegations  that  someone
connected with prosecution of the patent withheld relevant information from the USPTO, or made a misleading statement, during prosecution. Third parties
may also raise similar claims before administrative bodies in the United States or abroad, even outside the context of litigation. Such mechanisms include
re-examination,

31

post-grant review and/or inter partes review and equivalent proceedings in foreign jurisdictions, and opposition proceedings. Such proceedings could result
in revocation or amendment of our patents in such a way that they no longer cover our product candidates or competitive products. The outcome following
legal assertions of invalidity and unenforceability is unpredictable. With respect to validity, for example, we cannot be certain that there is no invalidating
prior  art,  of  which  we  and  the  patent  examiner  were  unaware  during  prosecution.  If  a  defendant  were  to  prevail  on  a  legal  assertion  of  invalidity  or
unenforceability, we would lose at least part, and perhaps all, of the patent protection on our product candidates.

Biopharmaceutical  patents  and  patent  applications  involve  highly  complex  legal  and  factual  questions,  which,  if  determined  adversely  to  us,  could
negatively impact our patent position.

The  patent  positions  of  biopharmaceutical  companies  can  be  highly  uncertain  and  involve  complex  legal  and  factual  questions.  The  interpretation  and
breadth  of  claims  allowed  in  some  patents  covering  biopharmaceutical  compositions  may  be  uncertain  and  difficult  to  determine  and  are  often  affected
materially  by  the  facts  and  circumstances  that  pertain  to  the  patented  compositions  and  the  related  patent  claims.  The  standards  of  the  U.S.  Patent  and
Trademark  Office,  or  USPTO,  are  evolving  and  could  change  in  the  future.  Consequently,  we  cannot  predict  the  issuance  and  scope  of  patents  with
certainty.  Patents,  if  issued,  may  be  challenged,  invalidated  or  circumvented.  U.S.  patents  and  patent  applications  may  also  be  subject  to  interference
proceedings, and U.S. patents may be subject to reexamination proceedings, post-grant review and/or inter partes review in the USPTO. Foreign patents
may be subject also to opposition or comparable proceedings in the corresponding foreign patent office, which could result in either loss of the patent or
denial  of  the  patent  application  or  loss  or  reduction  in  the  scope  of  one  or  more  of  the  claims  of  the  patent  or  patent  application.  In  addition,  such
interference, reexamination, post-grant review, inter partes review and opposition proceedings may be costly. Accordingly, rights under any issued patents
may not provide us with sufficient protection against competitive products or processes.

In addition, changes in or different interpretations of patent laws in the United States and foreign countries may permit others to use our or our licensors’
discoveries or to develop and commercialize our technology and products without providing any compensation to us, or may limit the number of patents or
claims we can obtain. The laws of some countries do not protect intellectual property rights to the same extent as U.S. laws and those countries may lack
adequate rules and procedures for defending our intellectual property rights.

If  we  fail  to  obtain  and  maintain  patent  protection  and  trade  secret  protection  for  our  product  candidates,  we  could  lose  our  competitive  advantage  and
competition we face would increase, reducing any potential revenues and adversely affecting our ability to attain or maintain profitability.

Developments in patent law could have a negative impact on our business.

From time to time, the U.S. Supreme Court, other federal courts, the U.S. Congress, the USPTO or similar foreign authorities may change the standards of
patentability  and  any  such  changes  could  have  a  negative  impact  on  our  business.  In  addition,  the  Leahy-Smith  America  Invents  Act,  or  the  America
Invents Act, which was signed into law in 2011, includes a number of significant changes to U.S. patent law. These changes include a transition from a
“first-to-invent”  system  to  a  “first-to-file”  system,  changes  to  the  way  issued  patents  are  challenged,  and  changes  to  the  way  patent  applications  are
disputed during the examination process. These changes may favor larger and more established companies that have greater resources to devote to patent
application filing and prosecution. The USPTO has developed new regulations and procedures to govern the full implementation of the America Invents
Act,  and  many  of  the  substantive  changes  to  patent  law  associated  with  the  America  Invents  Act,  and,  in  particular,  the  first-to-file  provisions,  became
effective  on  March  16,  2013.  Substantive  changes  to  patent  law  associated  with  the  America  Invents  Act,  or  any  subsequent  U.S.  legislation  regarding
patents, may affect our ability to obtain patents, and if obtained, to enforce or defend them. Accordingly, it is not clear what, if any, impact the America
Invents Act will have on the cost of prosecuting our U.S. patent applications, our ability to obtain U.S. patents based on our discoveries and our ability to
enforce or defend any patents that may issue from our patent applications, all of which could have a material adverse effect on our business.

If we do not obtain protection under the Hatch-Waxman Amendments and similar non-U.S. legislation for extending the term of patents covering each
of our product candidates, our business may be materially harmed.

Depending upon the timing, duration and conditions of FDA marketing approval of our product candidates, one or more of our U.S. patents may be eligible
for  limited  patent  term  extension  under  the  Drug  Price  Competition  and  Patent  Term  Restoration  Act  of  1984,  referred  to  as  the  Hatch-Waxman
Amendments, and similar legislation in the European Union. The Hatch-Waxman Amendments permit a patent term extension of up to five years for a
patent covering an approved product as compensation for effective patent term lost during product development and the FDA regulatory review process.
However, we may not receive an extension if we fail to apply within applicable deadlines, fail to apply prior to expiration of relevant patents or otherwise
fail to satisfy applicable requirements. Moreover, the length of the extension could be less than we request. If we are unable to obtain patent term extension
or the term of any such extension is less than we request, the period during which we can enforce our patent rights for that product will be shortened and
our competitors may obtain approval to market competing products sooner. As a result, our revenue from applicable products could be reduced, possibly
materially.

32

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

In addition to patent protection, because we operate in the highly technical field of development of therapies, we rely in part on trade secret protection in
order  to  protect  our  proprietary  technology  and  processes.  However,  trade  secrets  are  difficult  to  protect.  We  have  entered  into  confidentiality  and
intellectual property assignment agreements with our employees, consultants, outside scientific collaborators, sponsored researchers, and other advisors.
These agreements generally require that the other party keep confidential and not disclose to third parties all confidential information developed by the
party  or  made  known  to  the  party  by  us  during  the  course  of  the  party’s  relationship  with  us.  These  agreements  also  generally  provide  that  inventions
conceived by the party in the course of rendering services to us will be our exclusive property. However, these agreements may not be honored and may not
effectively assign intellectual property rights to us.

In  addition  to  contractual  measures,  we  try  to  protect  the  confidential  nature  of  our  proprietary  information  using  physical  and  technological  security
measures. Such measures may not, for example, in the case of misappropriation of a trade secret by an employee or third party with authorized access,
provide adequate protection for our proprietary information. Our security measures may not prevent an employee or consultant from misappropriating our
trade  secrets  and  providing  them  to  a  competitor,  and  recourse  we  take  against  such  misconduct  may  not  provide  an  adequate  remedy  to  protect  our
interests fully. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret can be difficult, expensive, and time-consuming, and the
outcome is unpredictable. In addition, courts outside the United States may be less willing to protect trade secrets. Trade secrets may be independently
developed by others in a manner that could prevent legal recourse by us. If any of our confidential or proprietary information, such as our trade secrets,
were  to  be  disclosed  or  misappropriated,  or  if  any  such  information  was  independently  developed  by  a  competitor,  our  competitive  position  could  be
harmed.

We will not seek to protect our intellectual property rights in all jurisdictions throughout the world and we may not be able to adequately enforce our
intellectual property rights even in the jurisdictions where we seek protection.

Filing,  prosecuting  and  defending  patents  on  our  product  candidates  in  all  countries  and  jurisdictions  throughout  the  world  would  be  prohibitively
expensive, and our intellectual property rights in some countries outside the United States could be less extensive than those in the United States, assuming
that rights are obtained in the United States. Competitors may use our technologies in jurisdictions where we do not pursue and obtain patent protection to
develop their own products and further, may export otherwise infringing products to territories where we have patent protection, but enforcement is not as
strong as that in the United States. These products may compete with our products and our patents or other intellectual property rights may not be effective
or sufficient to prevent them from competing. Even if we pursue and obtain issued patents in particular jurisdictions, our patent claims or other intellectual
property rights may not be effective or sufficient to prevent third parties from so competing.

In  addition,  the  laws  of  some  foreign  countries  do  not  protect  intellectual  property  rights  to  the  same  extent  as  the  federal  and  state  laws  in  the  United
States. Many companies have encountered significant problems in protecting and defending intellectual property rights in certain foreign jurisdictions. The
legal  systems  of  some  countries,  particularly  developing  countries,  do  not  favor  the  enforcement  of  patents  and  other  intellectual  property  protection,
especially those relating to biopharmaceuticals or biotechnologies. This could make it difficult for us to stop the infringement of our patents, if obtained, or
the misappropriation of our other intellectual property rights. For example, many foreign countries have compulsory licensing laws under which a patent
owner  must  grant  licenses  to  third  parties.  In  addition,  many  countries  limit  the  enforceability  of  patents  against  third  parties,  including  government
agencies or government contractors. In these countries, patents may provide limited or no benefit. Patent protection must ultimately be sought on a country-
by-country basis, which is an expensive and time-consuming process with uncertain outcomes. Accordingly, we may choose not to seek patent protection in
certain countries, and we will not have the benefit of patent protection in such countries.

Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of
our business, could put our patents at risk of being invalidated or interpreted narrowly, could put our patent applications at risk of not issuing and could
provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if any,
may not be commercially meaningful. In addition, changes in the law and legal decisions by courts in the United States and foreign countries may affect
our ability to obtain adequate protection for our technology and the enforcement of intellectual property. Accordingly, our efforts to enforce our intellectual
property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license.

33

Third parties may assert ownership to inventions we develop.

Collaborators or third party partners may in the future make claims challenging the inventorship or ownership of our intellectual property developed in the
context of their collaboration with us. We have written agreements with collaborators and third party partners that provide us the ownership of intellectual
property or provide that we must negotiate certain intellectual property rights with collaborators and third party partners with respect to joint inventions or
inventions made by them that arise from the results of the collaboration. In some instances, written provisions or conditions may be challenged or may not
be  adequate  to  address  clearly  the  resolution  of  intellectual  property  rights  that  may  arise  from  a  collaboration.  If  we  cannot  successfully  negotiate
ownership of intellectual property to the inventions that result from our use of a third-party partner or collaborator’s materials where required, or if disputes
otherwise arise with respect to the intellectual property developed with the use of a third-party partner or collaborator’s samples, we may be limited in our
ability  to  capitalize  on  the  market  potential  of  these  inventions.  In  addition,  we  may  face  claims  by  third  parties  that  our  agreements  with  employees,
contractors, or consultants obligating them to assign intellectual property to us are ineffective, or in conflict with prior or competing contractual obligations
of assignment, which could result in ownership disputes regarding intellectual property we have developed or will develop and interfere with our ability to
capture the commercial value of such inventions. Litigation may be necessary to resolve an ownership dispute, and if we are not successful, we may be
precluded  from  using  certain  intellectual  property,  or  may  lose  our  exclusive  rights  in  that  intellectual  property.  Either  outcome  could  have  an  adverse
impact on our business.

If we fail to comply with our obligations under license or technology agreements with third parties, we could lose license rights that are critical to our
business.

We license intellectual property that is critical to our business, including licenses underlying the technology in our diagnostic tests, and in the future, we
may enter into additional agreements that provide us with licenses to valuable intellectual property or technology. These licenses impose various royalty
payments,  milestones,  and  other  obligations  on  us.  If  we  fail  to  comply  with  any  of  these  obligations,  the  licensor  may  have  the  right  to  terminate  the
license. Termination by the licensor would cause us to lose valuable rights, and could prevent us from distributing our current tests, or inhibit our ability to
commercialize future test candidates. Our business would suffer if any current or future licenses terminate, if the licensors fail to abide by the terms of the
license, if the licensors fail to prevent infringement by third parties, if the licensed patents or other rights are found to be invalid or unenforceable, or if we
are unable to enter into necessary licenses on acceptable terms.

Third  parties  may  assert  that  our  employees  or  consultants  have  wrongfully  used  or  disclosed  confidential  information  or  misappropriated  trade
secrets.

We employ individuals who were previously employed at universities or other biotechnology or pharmaceutical companies, including our competitors or
potential competitors. Although we try to ensure that our employees and consultants do not use the proprietary information or know-how of others in their
work  for  us,  and  no  such  claims  against  us  are  currently  pending,  we  may  be  subject  to  claims  that  we  or  our  employees,  consultants  or  independent
contractors have used or disclosed intellectual property, including trade secrets or other proprietary information, of a former employer or other third parties.
Litigation may be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose
valuable intellectual property rights or personnel. Even if we are successful in defending against such claims, litigation could result in substantial costs and
be a distraction to management and other employees.

A dispute concerning the infringement or misappropriation of our proprietary rights or the proprietary rights of others could be time-consuming and
costly, and an unfavorable outcome could harm our business.

There is significant litigation in the biopharmaceutical industry regarding patent and other intellectual property rights. While we are not currently subject to
any  pending  intellectual  property  litigation,  and  are  not  aware  of  any  such  threatened  litigation,  we  may  be  exposed  to  future  litigation  by  third  parties
based on claims that our product candidates, technologies or activities infringe the intellectual property rights of others. If our development activities are
found to infringe any such patents, we may have to pay significant damages or seek licenses to such patents. A patentee could prevent us from using the
patented drugs or compositions. We may need to resort to litigation to enforce a patent issued to us, to protect our trade secrets, or to determine the scope
and validity of third-party proprietary rights. From time to time, we may hire scientific personnel or consultants formerly employed by other companies
involved  in  one  or  more  areas  similar  to  the  activities  conducted  by  us.  Either  we  or  these  individuals  may  be  subject  to  allegations  of  trade  secret
misappropriation or other similar claims as a result of prior affiliations. If we become involved in litigation, it could consume a substantial portion of our
managerial  and  financial  resources,  regardless  of  whether  we  win  or  lose.  We  may  not  be  able  to  afford  the  costs  of  litigation.  Any  adverse  ruling  or
perception of an adverse ruling in defending ourselves against these claims could have a negative impact on our cash position. Any legal action against us
or our collaborators could lead to:

•

•

payment of damages, potentially treble damages, if we are found to have willfully infringed a party’s patent rights;

injunctive or other equitable relief that may effectively block our ability to further develop, commercialize, and sell products; or

34

•

us or our collaborators having to enter into license arrangements that may not be available on commercially acceptable terms, if at all.

Any of these outcomes could hurt our cash position and financial condition and our ability to develop and commercialize our product candidates.

If our trademarks and trade names are not adequately protected, we may not be able to build name recognition in our markets of interest.

Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to be infringing on
other marks. We may not be able to protect our rights to these trademarks and trade names, which we will need to build name recognition by potential
partners or customers in our markets of interest. Over the long term, if we are unable to establish name recognition based on our trademarks and trade
names, we may not be able to compete effectively.

3.D.9. Risks Related to Ownership of our Securities and our Status as a Non-U.S. Company with Foreign Private Issuer Status

The market price of our equity securities may be volatile or may decline regardless of our operating performance.

The market price for our ADSs and ordinary shares has fluctuated and is likely to continue to fluctuate, substantially. The stock market in general and the
market for biopharmaceutical companies in particular have experienced extreme volatility that in some instances is unrelated to the operating performance
of particular companies. For example, on the day we announced our positive Phase 2b clinical trial results evaluating eryaspase in metastatic pancreatic
cancer in March 2017, the closing price per ordinary share on Euronext Paris increased by 71% compared to the average of the closing price per ordinary
share for the previous 20 trading days. Conversely, on the day we announced the negative results of our TRYbeCA-1 Phase 3 clinical trial in October 2021,
the share price decreased by 39% compared to the average of the closing price per ordinary share for the previous 20 trading days. A significant decrease in
our share price could have a significant adverse effect on our financial condition, reputation and prospects.

As a result of this volatility in our market and industry, holders of our equity securities may not be able to sell their ADSs or ordinary shares at or above the
price  originally  paid  for  the  security.  The  market  price  for  our  ADSs  and  ordinary  shares  may  be  influenced  by  numerous  factors,  some  of  which  are
beyond our control, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

actual or anticipated fluctuations in our financial condition and operating results;

actual or anticipated changes in our growth rate relative to our competitors;

competition from existing products or new products that may emerge;

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

failure to meet or exceed financial estimates and projections of the investment community or that we provide to the public;

issuance of new or updated research or reports by securities analysts;

fluctuations in the valuation of companies perceived by investors to be comparable to us;

share and ADS price and volume fluctuations attributable to inconsistent trading volume levels of our shares and ADSs;

additions or departures of key management or scientific personnel;

lawsuits threatened or filed against us, disputes or other developments related to proprietary rights, including patents, litigation matters, and our
ability to obtain patent protection for our technologies;

changes to coverage policies or reimbursement levels by commercial third-party payors and government payors and any announcements relating
to coverage policies or reimbursement levels;

announcement or expectation of additional debt or equity financing efforts;

adverse regulatory decisions, including failure to receive regulatory approval for any of our product candidates;

the termination of a strategic alliance or the inability to establish additional strategic alliances;

sales of our ordinary shares or ADSs by us, our insiders or our other shareholders; and

general economic and market conditions.

These and other market and industry factors may cause the market price and demand for our ordinary shares and ADSs to fluctuate substantially, regardless
of our actual operating performance, which may limit or prevent holders of our equity securities from readily selling their ordinary shares or ADSs and may
otherwise negatively affect the liquidity of the trading market for the ordinary shares and ADSs.

35

In  addition,  in  the  past,  stockholders  have  initiated  class  action  lawsuits  against  pharmaceutical  and  biotechnology  companies  following  periods  of
volatility  in  the  market  prices  of  these  companies’  stock.  Such  litigation,  if  instituted  against  us,  could  cause  us  to  incur  substantial  costs  and  divert
management’s attention and resources from our business.

The dual listing of our ordinary shares and our ADSs may adversely affect the liquidity and value of our ordinary shares and ADSs.

Our ADSs are listed on Nasdaq, and our ordinary shares are listed on Euronext Paris. We cannot predict the effect our dual listing will have on the value of
our ADSs and ordinary shares. However, the dual listing of our ADSs and ordinary shares may dilute the liquidity of these securities in one or both markets
and may adversely affect the trading market or price for our ADSs or ordinary shares.

If we do not achieve our projected development and commercialization goals in the timeframes we announce and expect, our business will be harmed
and the price of our securities could decline as a result.

We sometimes estimate for planning purposes the timing of the accomplishment of various scientific, clinical, regulatory and other product development
objectives. These milestones may include our expectations regarding the commencement or completion of scientific studies, clinical trials, the submission
of regulatory filings, or commercialization objectives. From time to time, we may publicly announce the expected timing of some of these milestones, such
as the completion of an ongoing clinical trial, the initiation of other clinical programs, receipt of marketing approval, or a commercial launch of a product.
The achievement of many of these milestones may be outside of our control. All of these milestones are based on a variety of assumptions which may
cause the timing of achievement of the milestones to vary considerably from our estimates, including:

•

•

•

•

•

•

•

our available capital resources or capital constraints we experience;

the rate of progress, costs and results of our clinical trials and research and development activities, including the extent of scheduling conflicts
with participating clinicians and collaborators, and our ability to identify and enroll patients who meet clinical trial eligibility criteria;

our receipt of approvals by the EMA, FDA and other regulatory agencies and the timing thereof;

other actions, decisions or rules issued by regulators;

our  ability  to  access  sufficient,  reliable  and  affordable  supplies  of  compounds  and  raw  materials  used  in  the  manufacture  of  our  product
candidates;

the efforts of our collaborators with respect to the commercialization of our products; and

the securing of, costs related to, and timing issues associated with, product manufacturing as well as sales and marketing activities.

If we fail to achieve announced milestones in the timeframes we expect, the commercialization of our product candidates may be delayed, our business and
results of operations may be harmed, and the trading price of the ordinary shares and ADSs may decline as a result.

Our ownership is concentrated in the hands of our principal shareholders and ADS holders and management, who continue to be able to exercise a
direct or indirect controlling influence on us.

As  of  December  31,  2021,  our  executive  officers,  directors,  current  5%  or  greater  shareholders  and  their  respective  affiliated  entities,  including  BVF
Partners L.P and Armistice Capital LLC, together beneficially owned approximately 25% of our ordinary shares (including ordinary shares in the form of
ADSs). As a result, these shareholders, acting together, will have significant influence over all matters that require approval by our shareholders, including
the election of directors and approval of significant corporate transactions. Corporate action might be taken even if other shareholders oppose them. This
concentration of ownership might also have the effect of delaying or preventing a change of control of our company that other shareholders may view as
beneficial.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, the price of the ordinary
shares and ADSs and their trading volume could decline.

The trading market for the ADSs and ordinary shares depends in part on the research and reports that securities or industry analysts publish about us or our
business. If no or few securities or industry analysts cover our company, the trading price for our ADSs and ordinary shares would be negatively impacted.
If one or more of the analysts who covers us downgrades our equity securities or publishes incorrect or unfavorable research about our business, the price
of the ordinary shares and ADSs would likely decline. If one or more of these analysts ceases coverage of our company or fails to publish reports on us
regularly, or downgrades our securities, demand for the ordinary shares and ADSs could decrease, which could cause the price of the ordinary shares and
ADSs or their trading volume to decline.

36

We do not currently intend to pay dividends on our securities and, consequently, the ability of our shareholders and ADS holders to achieve a return on
investment will depend on appreciation in the price of the ordinary shares and ADSs. In addition, French law may limit the amount of dividends we are
able to distribute.

We have never declared or paid any cash dividends on our share capital and do not currently intend to do so for the foreseeable future. We currently intend
to  invest  our  future  earnings,  if  any,  to  fund  our  growth.  Therefore,  our  shareholders  and  ADS  holders  are  not  likely  to  receive  any  dividends  for  the
foreseeable future and any increase in value will depend solely upon future appreciation. Consequently, holders of our equity securities may need to sell all
or part of their holdings of ordinary shares or ADSs after price appreciation, which may never occur, as the only way to realize any future gains.

Further, under French law, the determination of whether we have been sufficiently profitable to pay dividends is made on the basis of our statutory financial
statements prepared and presented in accordance with accounting standards applicable in France. Please see the section of this Annual Report titled “Item
10.B—Memorandum and Articles of Association” for further details on the limitations on our ability to declare and pay dividends and the taxes that may
become payable by us if we elect to pay a dividend. Therefore, we may be more restricted in our ability to declare dividends than companies not based in
France.

In addition, exchange rate fluctuations may affect the amount of euros that we are able to distribute, and the amount in U.S. dollars that our shareholders
receive upon the payment of cash dividends or other distributions we declare and pay in euros, if any. These factors could harm the value of our equity
securities, and, in turn, the U.S. dollar proceeds that holders receive from the sale of ADSs.

Future sales, or the possibility of future sales, of a substantial number of our ADSs or ordinary shares could adversely affect the market price of our
ADSs and ordinary shares.

As of December 31, 2021, 31,018,553 ordinary shares were issued and outstanding. Sales of a substantial number of shares of our ordinary shares or ADSs
in the public market, or the perception that these sales might occur, could depress the market price of our securities and could impair our ability to raise
capital through the sale of additional equity securities. A substantial number of our shares are now generally freely tradable, subject, in the case of sales by
our  affiliates,  to  the  volume  limitations  and  other  provisions  of  Rule  144  under  the  U.S.  Securities  Act  of  1933,  as  amended,  or  the  Securities  Act.  If
holders of these shares sell, or indicate an intent to sell, substantial amounts of our securities in the public market, the trading price of our securities could
decline significantly.

We have also filed a registration statement with the SEC to register the ordinary shares that may be issued under our equity incentive plans. The ordinary
shares subject to outstanding options under our equity incentive plans, ordinary shares reserved for future issuance under our equity incentive plans and
ordinary  shares  subject  to  outstanding  warrants  will  become  eligible  for  sale  in  the  public  market  in  the  future,  subject  to  certain  legal  and  contractual
limitations. Sales of a large number of the shares issued under these plans in the public market could have an adverse effect on the market price of our
securities. In addition, pursuant to the OCABSA Agreement, we may issue ordinary shares upon conversion of convertible notes and/or exercise of share
warrants. In the event that such ordinary shares are sold in the public market, such sales of ordinary shares pursuant to the OCABSA Agreement could also
have an adverse effect on the market price of our securities.

The rights of shareholders in companies subject to French corporate law differ in material respects from the rights of shareholders of corporations
incorporated in the United States.

We are a French company with limited liability. Our corporate affairs are governed by our bylaws and by the laws governing companies incorporated in
France. The rights of shareholders and the responsibilities of members of our board of directors are in many ways different from the rights and obligations
of shareholders in companies governed by the laws of U.S. jurisdictions. For example, in the performance of its duties, our board of directors is required by
French  law  to  consider  the  interests  of  our  company,  its  shareholders,  its  employees  and  other  stakeholders,  rather  than  solely  our  shareholders  and/or
creditors. It is possible that some of these parties will have interests that are different from, or in addition to, the interests of our shareholders or holders of
our  ADSs.  See  the  sections  of  this  Annual  Report  titled  “Item  10.  B—Memorandum  and  Articles  of  Association”  and  “Item  16.G—Corporate
Governance.”

U.S.  holders  of  our  equity  securities  may  have  difficulty  enforcing  civil  liabilities  against  our  company  and  directors  and  senior  management  and
experts named herein.

Certain members of our board of directors and senior management and certain experts named herein are non-residents of the United States, and all or a
substantial portion of our assets and the assets of such persons are located outside the United States. As a result, it may not be possible to serve process on
such persons or us in the United States or to enforce judgments obtained in U.S. courts against them or us based on civil liability provisions of the securities
laws of the United States. Additionally, it may be difficult to assert U.S. securities law claims in actions originally instituted outside of the United States.
Foreign  courts  may  refuse  to  hear  a  U.S.  securities  law  claim  because  foreign  courts  may  not  be  the  most  appropriate  forums  in  which  to  bring  such  a
claim. Even if a foreign court agrees to hear a claim, it may determine that the law of the jurisdiction in which the foreign court resides, and not U.S. law, is
applicable to the claim. Further, if U.S. law is found to be applicable, the content of applicable U.S. law must be proved as a fact, which can be a time-
consuming and costly process, and certain matters of procedure would still be governed by the law of the

37

jurisdiction  in  which  the  foreign  court  resides.  In  particular,  there  is  some  doubt  as  to  whether  French  courts  would  recognize  and  enforce  certain  civil
liabilities  under  U.S.  securities  laws  in  original  actions  or  judgments  of  U.S.  courts  based  upon  these  civil  liability  provisions.  In  addition,  awards  of
punitive damages in actions brought in the United States or elsewhere may be unenforceable in France. An award for monetary damages under the U.S.
securities  laws  would  be  considered  punitive  if  it  does  not  seek  to  compensate  the  claimant  for  loss  or  damage  suffered  but  is  intended  to  punish  the
defendant. French law provides that a shareholder, or a group of shareholders, may initiate a legal action to seek indemnification from the directors of a
corporation in the corporation’s interest if it fails to bring such legal action itself. If so, any damages awarded by the court are paid to the corporation and
any legal fees relating to such action may be borne by the relevant shareholder or the group of shareholders.

The enforceability of any judgment in France will depend on the particular facts of the case as well as the laws and treaties in effect at the time. The United
States  and  France  do  not  currently  have  a  treaty  providing  for  recognition  and  enforcement  of  judgments  (other  than  arbitration  awards)  in  civil  and
commercial matters.

Our bylaws and French corporate law contain provisions that may delay or discourage a takeover attempt.

Provisions  contained  in  our  bylaws  and  French  corporate  law  could  make  it  more  difficult  for  a  third-party  to  acquire  us,  even  if  doing  so  might  be
beneficial to our shareholders. In addition, provisions of our bylaws impose various procedural and other requirements, which could make it more difficult
for shareholders to effect certain corporate actions. These provisions include the following:

•

under French law, the owner of 90% of the share capital or voting rights of a public company listed on a regulated market in a Member State of
the  European  Union  or  in  a  state  party  to  the  European  Economic  Area,  or  EEA,  Agreement,  including  France,  has  the  right  to  force  out
minority shareholders following a tender offer made to all shareholders;

under French law, a non-resident of France as well as any French entity controlled by non-residents of France may have to file a declaration for
statistical purposes with the Bank of France (Banque de France) within 20 working days following the date of certain direct foreign investments
in us, including any purchase of our ADSs. In particular, such filings are required in connection with investments exceeding €15,000,000 that
lead to the acquisition of at least 10% of our share capital or voting rights or cross such 10% threshold. See “Item 10.B - Limitations Affecting
Shareholders of a French Company;”

under French law, certain investments in a French company relating to certain strategic industries by individuals or entities not residents in a
Member State of the European Union or controlled by individuals of entities not resident in a Member State of the European Union are subject
to prior authorization of the Ministry of Economy pursuant to Law n°2019-486 (and as from April 1, 2020 pursuant to the decree n°2019-1590).
See  “Item  10.B  -  Limitations  Affecting  Shareholders  of  a  French  Company;”.  Within  the  context  of  the  ongoing  COVID-19  pandemic,  the
French government has included biotechnologies in the list of strategic industries by a Ministerial order (arrêté) of April 27, 2020. See section
D "Risk Factors - Risks Related to our Financial Position and Capital Needs ";

a merger (i.e., in a French law context, a stock for stock exchange following which our company would be dissolved without being liquidated
into the acquiring entity and our shareholders would become shareholders of the acquiring entity) of our company into a company incorporated
in the European Union would require the approval of our board of directors as well as a two-thirds majority of the votes held by the shareholders
present, represented by proxy or voting by mail at the relevant meeting;

a  merger  of  our  company  into  a  company  incorporated  outside  of  the  European  Union  would  require  the  unanimous  approval  of  our
shareholders;

under French law, a cash merger is treated as a share purchase and would require the consent of each participating shareholder;

our shareholders have granted and may grant in the future our board of directors broad authorizations to increase our share capital or to issue
additional  ordinary  shares  or  other  securities,  such  as  warrants,  to  our  shareholders,  the  public  or  qualified  investors,  including  as  a  possible
defense following the launching of a tender offer for our shares;

our shareholders have preferential subscription rights on a pro rata basis on the future issuance by us of any additional securities for cash or a
set-off of cash debts, which rights may only be waived by the extraordinary general shareholders’ meeting (by a two-thirds majority vote) of our
shareholders or on an individual basis by each shareholder;

our  board  of  directors  has  the  right  to  appoint  directors  to  fill  a  vacancy  created  by  the  resignation  or  death  of  a  director,  for  the  remaining
duration of such director’s term of office and subject to the approval by the shareholders of such appointment at the next shareholders’ meeting,
which prevents shareholders from having the sole right to fill vacancies on our board of directors;

our board of directors can be convened by our chairman or our managing director, if any, or, when no board meeting has been held for more than
two consecutive months, by directors representing at least one third of the total number of directors;

our board of directors meetings can only be regularly held if at least half of the directors attend either physically or by way of videoconference
or teleconference enabling the directors’ identification and ensuring their effective participation in the board’s decisions;

our shares are nominative or bearer, if the legislation so permits, according to the shareholder’s choice;

approval  of  at  least  a  majority  of  the  votes  held  by  shareholders  present,  represented  by  a  proxy,  or  voting  by  mail  at  the  relevant  ordinary
shareholders’ general meeting is required to remove directors with or without cause;

advance notice is required for nominations to the board of directors or for proposing matters to be acted upon at a shareholders’ meeting, except
that a vote to remove and replace a director can be proposed at any shareholders’ meeting without notice;

our bylaws can be changed in accordance with applicable laws;

the crossing of certain thresholds has to be disclosed and can impose certain obligations; see the section of this Annual Report titled “Item 10.B
—Memorandum and Articles of Association”;

transfers of shares shall comply with applicable insider trading rules and regulations and, in particular, with the Market Abuse Directive and
Regulation dated April 16, 2014; and

pursuant to French law, the sections of our bylaws relating to the number of directors and election and removal of a director from office, may
only be modified by a resolution adopted by two-thirds of the votes held by our shareholders present, represented by a proxy or voting by mail
at the meeting.

Holders of our ADSs may not be able to exercise their right to vote the ordinary shares underlying such ADSs.

Holders of our ADSs may exercise voting rights with respect to the ordinary shares represented by the ADSs only in accordance with the provisions of the
amended and restated deposit agreement. The amended and restated deposit agreement provides that, upon receipt of notice of any meeting of holders of
our ordinary shares, the depositary will fix a record date for the determination of ADS holders who shall be entitled to give instructions for the exercise of
voting rights. Upon timely receipt of notice from us, if we so request, the depositary shall distribute to the holders as of the record date (1) the notice of the
meeting or solicitation of consent or proxy sent by us and (2) a statement as to the manner in which instructions may be given by the holders.

Holders of our ADSs may instruct the depositary of their ADSs to vote the ordinary shares underlying such ADSs. Otherwise, holders of our ADSs will not
be able to exercise voting rights unless they withdraw the ordinary shares underlying the ADSs they hold. However, a holder of our ADSs may not know
about the meeting far enough in advance to withdraw those ordinary shares. If we ask for a holder of our ADSs’ instructions, the depositary, upon timely
notice from us, will notify him or her of the upcoming vote and arrange to deliver our voting materials to him or her. We cannot guarantee to any holder of
ADSs that he or she will receive the voting materials in time to ensure that he or she can instruct the depositary to vote his or her ordinary shares or to
withdraw his or her ordinary shares so that he or she can vote them directly. Pursuant to the terms of our amended deposit agreement, in certain situations
if, in the opinion of our management, the matter is not materially adverse to the interests of our shareholders, we may request that if the depositary does not
receive  timely  voting  instructions  from  a  holder  of  ADSs,  the  depositary  may  give  a  proxy  to  a  person  designated  by  us  to  vote,  in  its  discretion,  the
ordinary shares underlying the unvoted ADSs, as long as the matter is endorsed by our board. In addition, the depositary and its agents are not responsible
for  failing  to  carry  out  voting  instructions  or  for  the  manner  of  carrying  out  voting  instructions.  This  means  that  a  holder  of  ADSs  may  not  be  able  to
exercise his or her right to vote, and there may be nothing he or she can do if the ordinary shares underlying his or her ADSs are not voted as he or she
requested.

The  right  as  a  holder  of  ADSs  to  participate  in  any  future  preferential  subscription  rights  or  to  elect  to  receive  dividends  in  shares  may  be  limited,
which may cause dilution to the holders of our ADSs.

Under French law, if we issue additional securities for cash, current shareholders will have preferential subscription rights for these securities on a pro rata
basis unless they waive those rights at an extraordinary meeting of our shareholders (by a two-thirds majority vote) or individually by each shareholder.
However, our ADS holders in the United States will not be entitled to exercise or sell such rights unless we register the rights and the securities to which
the rights relate under the Securities Act or an exemption from the registration requirements is available. In addition, the amended and restated deposit
agreement provides that the depositary will not make rights available to holders of our ADSs unless the distribution to ADS holders of both the rights and
any related securities are either registered under the Securities Act or exempted from registration under the Securities Act. Further, if we offer holders of
our ordinary shares the option to receive dividends in either cash or shares, under the amended and restated deposit agreement the depositary may require
satisfactory  assurances  from  us  that  extending  the  offer  to  holders  of  our  ADSs  does  not  require  registration  of  any  securities  under  the  Securities  Act
before making the option available to holders of our ADSs. We are under no obligation to file a registration statement with respect to any such rights or
securities  or  to  endeavor  to  cause  such  a  registration  statement  to  be  declared  effective.  Moreover,  we  may  not  be  able  to  establish  an  exemption  from
registration  under  the  Securities  Act.  Accordingly,  ADS  holders  may  be  unable  to  participate  in  our  rights  offerings  or  to  elect  to  receive  dividends  in
shares and may experience dilution in their holdings. In addition, if the depositary is unable to sell rights that are not exercised or not distributed or if the
sale is not lawful or reasonably practicable, it will allow the rights to lapse, in which case holders of our ADSs will receive no value for these rights.

39

Holders of our ADSs may be subject to limitations on the transfer of such ADSs and the withdrawal of the underlying ordinary shares.

ADSs, which may be evidenced by ADRs, are transferable on the books of the depositary. However, the depositary may close its books at any time or from
time to time when it deems expedient in connection with the performance of its duties. The depositary may refuse to deliver, transfer or register transfers of
ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary think it is advisable to do so because of any
requirement  of  law,  government  or  governmental  body,  or  under  any  provision  of  the  amended  and  restated  deposit  agreement,  or  for  any  other  reason
subject to an ADS holder’s right to cancel such ADSs and withdraw the underlying ordinary shares. Temporary delays in the cancellation of such ADSs and
withdrawal  of  the  underlying  ordinary  shares  may  arise  because  the  depositary  has  closed  its  transfer  books  or  we  have  closed  our  transfer  books,  the
transfer of ordinary shares is blocked to permit voting at a shareholders’ meeting or we are paying a dividend on our ordinary shares. In addition, a holder
of ADSs may not be able to cancel his or her ADSs and withdraw the underlying ordinary shares when he or she owes money for fees, taxes and similar
charges  and  when  it  is  necessary  to  prohibit  withdrawals  in  order  to  comply  with  any  laws  or  governmental  regulations  that  apply  to  ADSs  or  to  the
withdrawal of ordinary shares or other deposited securities.

As a foreign private issuer, we are exempt from a number of rules under the U.S. securities laws and are permitted to file less information with the SEC
than a U.S. company. This may limit the information available to holders of our ADSs or ordinary shares.

We are a foreign private issuer, as defined in the SEC’s rules and regulations and, consequently, we are not subject to all of the disclosure requirements
applicable to public companies organized within the United States. For example, we are exempt from certain rules under the U.S. Securities Exchange Act
of 1934, as amended, or the Exchange Act, that regulate disclosure obligations and procedural requirements related to the solicitation of proxies, consents
or  authorizations  applicable  to  a  security  registered  under  the  Exchange  Act,  including  the  U.S.  proxy  rules  under  Section  14  of  the  Exchange  Act.  In
addition,  our  officers  and  directors  are  exempt  from  the  reporting  and  “short-swing”  profit  recovery  provisions  of  Section  16  of  the  Exchange  Act  and
related rules with respect to their purchases and sales of our securities. Moreover, while we currently make annual and semi-annual filings with respect to
our listing on Euronext Paris and expect to continue to file such reports, we are not required to file periodic reports and financial statements with the SEC
as frequently or as promptly as U.S. public companies and we are not required to file quarterly reports on Form 10-Q or current reports on Form 8-K under
the Exchange Act. Accordingly, there is less publicly available information concerning our company than there would be if we were a U.S. domestic issuer.

As  a  foreign  private  issuer,  we  are  permitted  and  we  follow  certain  home  country  practices  in  relation  to  corporate  governance  matters  that  differ
significantly from Nasdaq’s corporate governance standards. These practices may afford less protection to shareholders than they would enjoy if we
complied fully with the corporate governance standards of the Nasdaq Global Select Market.

As a foreign private issuer listed on the Nasdaq Global Select Market, we are subject to Nasdaq’s corporate governance standards. However, Nasdaq rules
provide  that  foreign  private  issuers  are  permitted  to  follow  home  country  corporate  governance  practices  in  lieu  of  Nasdaq’s  corporate  governance
standards as long as notification is provided to Nasdaq of the intention to take advantage of such exemptions. We currently rely on exemptions for foreign
private  issuers  and  follow  French  corporate  governance  practices  in  lieu  of  Nasdaq’s  corporate  governance  standards,  to  the  extent  possible.  Certain
corporate governance practices in France, which is our home country, may differ significantly from Nasdaq corporate governance standards. For example,
as a French company, neither the corporate laws of France nor our bylaws require a majority of our directors to be independent and we can include non-
independent directors as members of our remuneration committee, and our independent directors are not required to hold regularly scheduled meetings at
which only independent directors are present.

We are also exempt from provisions set forth in Nasdaq rules which require an issuer to provide in its bylaws for a generally applicable quorum, and that
such quorum may not be less than one-third of the outstanding voting stock. Consistent with French law, our bylaws provide that a quorum requires the
presence  of  shareholders  having  at  least  (1)  20%  of  the  shares  entitled  to  vote  in  the  case  of  an  ordinary  shareholders’  general  meeting  or  at  an
extraordinary shareholders’ general meeting where shareholders are voting on a capital increase by capitalization of reserves, profits or share premium, or
(2) 25% of the shares entitled to vote in the case of any other extraordinary shareholders’ general meeting. In addition, Nasdaq Marketplace Rule 5635
requires a U.S. domestic listed company to obtain shareholder approval: (1) prior to the issuance of securities when the issuance or potential issuance will
result in a change of control of the issuer; (2) prior to the issuance of securities in connection with a transaction other than a public offering involving the
sale, issuance or potential issuance by the issuer alone, or together with sales by its officers, directors or substantial shareholders, of common stock (or
securities convertible into or exercisable for common stock) equal to 20% or more of the common stock or 20% or more of the voting power outstanding
before the issuance for less than the greater of book or market value; and (3) prior to the issuance of securities when an equity compensation arrangement is
made or materially amended, including prior to the issuance of common stock to the issuer’s officers, director, employees or consultants for less than the
greater of book or market value. While French law requires a French company to obtain prior shareholder approval to issue shares, its shareholders may
pre-authorize the company’s board of directors to issue shares such that shareholder approval is not required at the time of issuance.

40

As a foreign private issuer, we are required to comply with Rule 10A-3 of the Exchange Act, relating to audit committee composition and responsibilities.
Under French law, the audit committee may only have an advisory role and appointment of our statutory auditors, in particular, must be decided by the
shareholders at our annual meeting.

Therefore, our shareholders may be afforded less protection than they otherwise would have under Nasdaq’s corporate governance standards applicable to
U.S. domestic issuers.

We are an “emerging growth company” under the JOBS Act and are able to avail ourselves of reduced disclosure requirements applicable to emerging
growth companies, which could make our ADSs less attractive to investors.

We  are  an  “emerging  growth  company,”  as  defined  in  the  U.S.  Jumpstart  Our  Business  Startups  Act  of  2012,  or  the  JOBS  Act,  and  we  intend  to  take
advantage  of  certain  exemptions  from  various  reporting  requirements  that  are  applicable  to  other  public  companies  that  are  not  “emerging  growth
companies,” including not being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act of 2002, or the
Sarbanes-Oxley Act, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of
any golden parachute payments not previously approved. In addition, Section 107 of the JOBS Act also provides that an emerging growth company can
take  advantage  of  the  extended  transition  period  provided  in  Section  7(a)(2)(B)  of  the  Securities  Act  for  complying  with  new  or  revised  accounting
standards. We have elected not to take advantage of the extended transition period provided under Section 7(a)(2)(B) of the Securities Act for complying
with new or revised accounting standards. Since IFRS makes no distinction between public and private companies for purposes of compliance with new or
revised accounting standards, the requirements for our compliance as a private company and as a public company are the same.

We cannot predict if holders of our ADSs will find the ADSs less attractive because we may rely on these exemptions. If some holders find the ADSs less
attractive as a result, there may be a less active trading market for the ADSs and the price of the ADSs may be more volatile. We may take advantage of
these reporting exemptions until we are no longer an emerging growth company. We will remain an emerging growth company until the earliest of (i) the
last day of the fiscal year in which we have total annual gross revenue of $1.07 billion or more; (ii) December 31, 2022, which is the last day of our fiscal
year following the fifth anniversary of the date of the completion of our November 2017 global offering; (iii) the date on which we have issued more than
$1.0 billion in nonconvertible debt during the previous three years; and (iv) the date on which we are deemed to be a large accelerated filer under the rules
of the SEC.

We may lose our foreign private issuer status in the future, which could result in significant additional cost and expense.

While we currently qualify as a foreign private issuer, the determination of foreign private issuer status is made annually on the last business day of our
most recently completed second fiscal quarter and, accordingly, the next determination will be made with respect to us on June 30, 2022. In the future, we
would lose our foreign private issuer status if we fail to meet the requirements necessary to maintain our foreign private issuer status as of the relevant
determination  date.  We  will  remain  a  foreign  private  issuer  until  such  time  that  more  than  50%  of  our  outstanding  voting  securities  are  held  by  U.S.
residents and any of the following three circumstances applies: (i) the majority of our executive officers or directors are U.S. citizens or residents; (ii) more
than 50% of our assets are located in the United States; or (iii) our business is administered principally in the United States.

The regulatory and compliance costs to us under U.S. securities laws as a U.S. domestic issuer would likely be significantly more than costs we incur as a
foreign private issuer. If we lost our foreign private issuer status, we would be required to file periodic reports and registration statements on U.S. domestic
issuer  forms  with  the  SEC,  which  are  more  detailed  and  extensive  in  certain  respects  than  the  forms  available  to  a  foreign  private  issuer.  We  would  be
required under current SEC rules to prepare our financial statements in accordance with U.S. GAAP, rather than IFRS, and modify certain of our policies to
comply  with  corporate  governance  practices  associated  with  U.S.  domestic  issuers.  Such  conversion  of  our  financial  statements  to  U.S.  GAAP  would
involve significant time and cost. In addition, we would lose our ability to rely upon exemptions from certain corporate governance requirements on U.S.
stock exchanges that are available to foreign private issuers such as the ones described herein and exemptions from procedural requirements related to the
solicitation of proxies.

U.S. holders of our ADSs may suffer adverse tax consequences if we are characterized as a passive foreign investment company.

Generally, if, for any taxable year, at least 75% of our gross income is passive income, or at least 50% of the value of our assets is attributable to assets that
produce  passive  income  or  are  held  for  the  production  of  passive  income,  including  cash,  we  will  be  characterized  as  a  passive  foreign  investment
company, or PFIC, for U.S. federal income tax purposes. For purposes of these tests, passive income includes dividends, allocations of income with respect
to any partnership, interest, and gains from the sale or exchange of investment property and rents and royalties other than rents and royalties which are
received from unrelated parties in connection with the active conduct of a trade or business. If we are characterized as a PFIC, U.S. holders (as defined
below  under  “Item  10.  E.  Taxation—Material  U.S.  Federal  Income  Tax  Considerations”)  of  our  ADSs  may  suffer  adverse  tax  consequences,  including
having gains realized on the sale of the ADSs treated as ordinary income, rather than capital gain, the loss of the preferential rate applicable to dividends
received on the ADSs by individuals who are U.S. holders and having interest charges apply to distributions by us and the

41

proceeds  of  sales  of  the  ADSs.  See  “Item  10.  E.  Taxation—Material  U.S.  Federal  Income  Tax  Considerations—Passive  Foreign  Investment  Company
Considerations.”

The annual determination of whether we are a PFIC for a taxable year is fact-intensive and made after the close of such taxable year applying principles
and methodologies that in some circumstances are unclear and subject to varying interpretations. For instance, whether we are a PFIC will depend on the
composition of our income (including whether we will receive certain non-refundable grants or subsidies and whether such amounts and reimbursements of
certain  refundable  research  tax  credits  will  constitute  gross  income  for  purposes  of  the  PFIC  rules).  Whether  we  are  a  PFIC  also  will  depend  on  the
composition and value of our assets, including goodwill, which may be determined in large part by reference to the market value of our ADSs from time to
time, which may fluctuate considerably. If our market capitalization declines while we hold a substantial amount of cash and cash-equivalents, which may
depend on how quickly we utilize our cash proceeds from our global offerings in our business, we may be more likely to be characterized as a PFIC. Based
on the composition of our gross income, assets, activities and market capitalization and the nature of our business and due to fluctuations in our stock price,
we believe that we may have been characterized as a PFIC for our taxable year ending December 31, 2021. However, because our PFIC status is subject to
a number of uncertainties and it is very early in the year, we cannot provide any assurances, and our U.S. counsel expresses no opinion, with respect to our
PFIC status for any taxable year.

If a U.S. holder is treated as owning at least 10% of our ADSs, such holder may be subject to adverse U.S. federal income tax consequences.

If  a  U.S.  holder  (as  defined  below  under  “Item  10.  E.  Taxation—Material  U.S.  Federal  Income  Tax  Considerations”)  is  treated  as  owning  (directly,
indirectly or constructively) at least 10% of the value or voting power of our ADSs, such U.S. holder will be treated as a “United States shareholder” with
respect to each “controlled foreign corporation” in our group (if any). Because our group includes at least one U.S. subsidiary (ERYTECH Pharma, Inc.), if
we  were  to  form  or  acquire  any  non-U.S.  subsidiaries  in  the  future,  they  may  be  treated  as  controlled  foreign  corporations.  A  U.S.  shareholder  of  a
controlled foreign corporation will be required to annually report and include in its U.S. taxable income its pro rata share of “Subpart F income,” “global
intangible low-taxed income” and investments in U.S. property by the controlled foreign corporations, regardless of whether we make any distributions. An
individual that is a U.S. shareholder with respect to a controlled foreign corporation generally would not be allowed certain tax deductions or foreign tax
credits  that  would  be  allowed  to  a  U.S.  shareholder  that  is  a  U.S.  corporation.  We  cannot  provide  any  assurances  that  we  will  assist  U.S.  holders  in
determining whether any non-U.S. subsidiaries that we may form or acquire in the future would be treated as a controlled foreign corporation or whether
such  U.S.  holder  would  be  treated  as  a  U.S.  shareholder  with  respect  to  any  of  such  controlled  foreign  corporations.  Further,  we  cannot  provide  any
assurances that we will furnish to any U.S. holder that is a U.S. shareholder the information that may be necessary to comply with the reporting and tax
paying obligations discussed above. Failure to comply with these reporting and tax paying obligations may subject a U.S. holder that is a U.S. shareholder
to significant monetary penalties and may prevent from starting the statute of limitations with respect to such U.S. holder's U.S. federal income tax return
for the taxable year in which such obligations was required. U.S. holders should consult their tax advisors regarding the potential application of these rules
to their investment in our ADSs.

We have identified a material weakness in our internal control over financial reporting. If we are unable to remediate these material weakness, or if we
experience additional material weaknesses in the future or otherwise fail to maintain an effective system of internal controls, we may not be able to
accurately or timely report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a result, the
trading price of our ADSs or ordinary shares.

We have identified one material weakness in our internal control over financial reporting as of December 31, 2018, which has not been remediated as of
December 31, 2021. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a
reasonable possibility that a material misstatement of our financial statements will not be prevented or detected on a timely basis.

If  we  are  unable  to  remediate  this  material  weakness,  or  if  we  experience  additional  material  weaknesses  in  the  future  or  otherwise  fail  to  maintain  an
effective system of internal controls, we may not be able to accurately or timely report our financial condition or results of operations, which may adversely
affect investor confidence in us and, as a result, the value of our securities.

As  of  December  31,  2019  and  December  31,  2020,  we  concluded  that  our  internal  control  over  financial  reporting  was  not  effective  as  a  result  of  two
material weaknesses in our internal control over financial reporting related to: (i) the monitoring of research and development projects, as controls designed
to track actual costs incurred against invoices received were not operating at a sufficient level of precision due to insufficient personnel with an appropriate
level of knowledge and training in internal control over complex processes; and (ii) the lack of sufficiently developed and documented internal controls for
our U.S. subsidiary.

In  connection  with  our  assessment  as  of  December  31,  2021,  our  management  concluded  that  the  material  weakness  related  to  the  lack  of  sufficiently
developed and documented internal controls for our U.S. subsidiary had been remediated. However, we concluded that that the material weakness related to
the monitoring of research and development projects was not fully remediated.

42

During  2021,  we  continued  to  strengthen  our  internal  controls  over  research  and  development  financial  information,  in  particular  we  finalized  the
implementation of controls designed to track actual costs incurred against invoices received, in order to better detect and correct errors. During 2021, we
also trained personnel on internal controls over complex processes.

We believe the remediation measures described above improved the reliability of financial information related to research and development. Nevertheless,
our management identified that the control over the reconciliation of estimated hospital costs incurred related to clinical trials sponsored by the Company
with  invoices  received  did  not  operate  at  a  sufficient  level  of  precision.  Management  considers  this  control  has  to  be  redesigned  to  fully  remediate  the
material weakness.

To further improve our internal control over financial reporting and to specifically address the control deficiency that led to our material weakness, we plan
to deploy remediation efforts focused on reinforcing:

•

controls  over  our  research  and  development  financial  information,  including  redesigning  our  key  control  over  the  reconciliation  of  invoices
received with estimated hospital costs incurred related to clinical trials sponsored by the Company so that it can operate at an appropriate level of
precision to detect and correct errors.

We believe that these activities will further support the remediation of this material weakness. However, we cannot assure you that the measures we have
taken to date, and actions we may take in the future, will be sufficient to remediate the control deficiency that led to our material weakness in our internal
control  over  financial  reporting  or  that  they  will  prevent  or  avoid  potential  future  material  weaknesses.  In  addition,  our  independent  registered  public
accounting firm has not performed an evaluation of our internal control over financial reporting in accordance with the provisions of the Sarbanes-Oxley
Act because no such evaluation has been required. Had our independent registered public accounting firm performed an evaluation of our internal control
over financial reporting in accordance with the provisions of the Sarbanes-Oxley Act, additional material weaknesses may have been identified. If we are
unable to successfully remediate our existing or any future material weaknesses in our internal control over financial reporting, or identify any additional
material  weaknesses,  the  accuracy  and  timing  of  our  financial  reporting  may  be  adversely  affected,  we  may  be  unable  to  maintain  compliance  with
securities law requirements regarding timely filing of reports in addition to applicable stock exchange listing requirements, investors may lose confidence
in our financial reporting, and the trading price of our ADSs or ordinary shares may decline as a result.

If we fail to establish and maintain proper internal controls, our ability to produce accurate financial statements or comply with applicable regulations
could be impaired.

We are required, pursuant to Section 404(a) of the Sarbanes-Oxley Act, or Section 404(a), to furnish a report by management on, among other things the
effectiveness of our internal control over financial reporting on an annual basis. This assessment includes disclosure of any material weaknesses identified
by our management in our internal control over financial reporting. In connection with the preparation of our financial results for the year ended December
31, 2021, we identified one material weakness in our internal control over financial reporting. Our Management’s Report on Internal Control over Financial
Reporting included in this Annual Report describes this material weakness and includes our conclusion that our internal controls were not effective as of
the  end  of  the  period  covered  by  this  Annual  Report.  While  we  have  established  certain  procedures  and  control  over  our  financial  reporting  processes,
including  initiating  remediation  efforts  with  respect  to  the  material  weakness,  we  cannot  assure  you  that  these  efforts  will  prevent  restatements  of  our
financial  statements  in  the  future.  Although  Section  404(b)  of  the  Sarbanes-Oxley  Act,  or  Section  404(b),  requires  our  independent  registered  public
accounting  firm  to  issue  an  annual  report  that  addresses  the  effectiveness  of  our  internal  control  over  financial  reporting,  we  have  opted  to  rely  on  the
exemptions provided in the JOBS Act, and consequently will not be required to comply with SEC rules that implement Section 404(b) until such time as
we are no longer an EGC.

The presence of material weaknesses could result in financial statement errors which, in turn, could lead to errors in our financial reports, delays in our
financial reporting, which could require us to restate our operating results or our auditors may be required to issue a qualified audit report. We might not
identify one or more material weaknesses in our internal controls in connection with evaluating our compliance with Section 404(a). In order to maintain
and improve the effectiveness of our disclosure controls and procedures and internal control over financial reporting, we will need to expend significant
resources and provide significant management oversight. Implementing any appropriate changes to our internal control may require specific compliance
training of our directors and employees, entail substantial costs in order to modify our existing accounting systems, take a significant period of time to
complete and divert management’s attention from other business concerns. These changes may not, however, be effective in achieving and maintaining the
adequacy of our internal control.

If either we are unable to conclude that we have effective internal control over financial reporting, as is the case currently, or, at the appropriate time, our
independent auditors are unwilling or unable to provide us with an unqualified report on the effectiveness of our internal control over financial reporting as
required  by  Section  404(b),  investors  may  lose  confidence  in  the  accuracy  or  completeness  of  our  financial  reports,  the  price  of  our  ADSs  or  ordinary
shares could decline and we may be subject to litigation, sanctions or investigations by regulatory authorities, including the SEC and Nasdaq. Failure to
remediate  any  material  weakness  in  our  internal  control  over  financial  reporting,  or  to  maintain  other  effective  control  systems  required  of  public
companies, could also restrict our

43

future access to the capital markets. In addition, if we are unable to meet the requirements of Section 404, we may not be able to remain listed on Nasdaq.

respectively. These capital expenditures were related primarily to the buildup of our fixed assets for our pharmaceutical facility and laboratory and to a
lesser extent to the purchase of office and computer equipment. We do not capitalize clinical research and development costs until we obtain marketing
authorization for a product candidate.

4.B.Business Overview

4.B.1. Overview

®

We  are  a  clinical-stage  biopharmaceutical  company  developing  innovative  therapies  for  severe  forms  of  cancer  and  orphan  diseases.  Leveraging  our
proprietary ERYCAPS   platform,  which  uses  a  novel  technology  to  encapsulate  therapeutic  drug  substances  inside  erythrocytes,  or  red  blood  cells,  or
RBCs, we are developing a pipeline of product candidates for patients with high unmet medical needs. Our lead product candidate eryaspase, which we
also refer to as GRASPA , targets the metabolism of cancer cells by depriving them of asparagine, an amino acid necessary for their survival and critical in
maintaining the cells’ rapid growth rate. We are currently developing eryaspase for the treatment of patients with severe forms of cancer, including acute
lymphoblastic leukemia, or ALL, pancreatic cancer and triple negative breast cancer, or TNBC.

®

Since 2017, we supported a Phase 2 clinical trial initiated and sponsored by investigators of the Nordic Society of Pediatric Hematology and Oncology, or
NOPHO.  This  trial  evaluated  the  safety  and  pharmacological  profile  of  eryaspase  in  ALL  patients,  who  developed  hypersensitivity  reactions  to  prior
asparaginase treatment or silent inactivation to pegylated L-asparaginase. In December 2020, positive results from the trial were presented at the American
Society of Hematology 2020 Annual Meeting. The trial was conducted at 21 clinical sites in the Nordic and Baltic countries of Europe and enrolled 55
patients.  The  main  objectives  of  the  trial  were  the  activity  and  safety  of  eryaspase.  Both  objectives  were  met.  In  July  2021,  we  announced  a  pre-BLA
meeting with the U.S. Food and Drug Administration, or FDA to evaluate the possibility of pursuing regulatory approval for eryaspase in the United States
in  this  indication  based  on  this  IST  Phase  2  clinical  trial.  Based  on  the  discussions  and  the  totality  of  the  information  available  to  date,  we  believe  our
regulatory  package  can  potentially  support  an  approval  of  eryaspase  in  hypersensitive  ALL  patients.  In  July  2021,  eryaspase  was  granted  Fast  Track
Designation  by  the  FDA  for  the  treatment  of  ALL  patients  who  have  developed  hypersensitivity  reactions  to  E.coli-derived  asparaginase.  Pending
successful completion of remaining steps, we anticipate filing a BLA in the third quarter of 2022.

44

In 2018, we initiated a pivotal Phase 3 clinical trial of eryaspase for the treatment of second-line advanced pancreatic cancer patients. Patient enrollment in
this trial, which we refer to as the TRYbeCA-1 trial, began in September 2018 in Europe. We have obtained clinical trial authorizations in the United States
and from 11 European Union countries and have conducted the clinical trial at close to 90 clinical sites. In April 2020, the FDA, granted eryaspase Fast
Track Designation as a potential second-line treatment for patients with metastatic pancreatic cancer. Eryaspase has also received orphan drug designation
for pancreatic cancer in both the United States and Europe. We completed the patient enrollment in the TRYbeCA-1 trial in December 2020. A total of 512
patients participated in the trial, slightly above the target enrollment of 482 patients. We reported top-line final results on October 25, 2021. The Phase 3
TRYbeCA-1 trial did not meet the primary efficacy endpoint of overall survival (OS). Nevertheless, a preliminary analysis of the results of a subgroup of
patients  indicated  a  potential  efficacy  signal  for  patients  treated  with  eryaspase  in  combination  with  FOLFIRI  chemotherapy  cocktail.  Potential
continuation of development in pancreatic cancer was discussed with Key Opinion Leaders, who confirmed that further exploration of the combination of
eryaspase with irinotecan- and fluoropyrimidine-based chemotherapy is of interest, and who recommended to consider further development in later lines of
treatment.

We are also supporting a Phase 1 investigator-sponsored clinical trial, or IST, which we refer to as the rESPECT trial, evaluating the safety of eryaspase in
combination with modified FOLFIRINOX for the treatment of first-line advanced pancreatic cancer patients. The Georgetown Lombardi Comprehensive
Cancer Center is the sponsor of this trial. We announced the enrollment of the first patient in this trial in January 2021, and in October 2021, after review of
the  safety  data  of  six  additional  patients  comprising  the  second  treatment  cohort,  we  announced  the  determination  of  the  maximum  tolerated  dose.  In
January  2022,  encouraging  data  from  the  study  were  presented  at  the  American  Society  of  Clinical  Oncology  (ASCO  GI)  Gastrointestinal  Cancers
Symposium,  A  total  of  approximately  18  patients  is  expected  to  be  enrolled  in  the  trial  at  the  maximum  tolerated  dose  level.  Reporting  of  final  data  is
expected in the third quarter of 2022.

We launched a proof-of-concept Phase 2 clinical trial in TNBC in the European Union, which we refer to as the TRYbeCA-2 trial, in the fourth quarter of
2018. Following the publication of the negative results of the TRYbeCA-1 study, and with a goal of reducing costs and preserving cash flow, it has been
announced  in  November  2021  that  recruitment  of  new  patients  in  this  study  will  be  stopped.  The  results  from  the  patients  enrolled  prior  to  the  end  of
recruitment in the TRYbeCA-2 trial to date are expected to be reported around mid-2022.

In addition to the encapsulation of L-asparaginase, we believe that our ERYCAPS  platform has broad potential application and can be used to encapsulate
a  wide  range  of  therapeutic  agents  for  which  long-circulating  therapeutic  activity  or  rapid  and  specific  targeting  is  desired.  For  example,  we  developed
erymethionase,  a  preclinical  product  candidate  which  encapsulates  methionine-γ-lyase  in  RBCs  and  is  designed  to  target  the  amino  acid  metabolism  of
cancer  cells  and  induce  tumor  starvation.  We  intend  to  continue  to  work  on  the  development  of  erymethionase  as  well  as  potential  other  therapeutic
strategies  based  on  methionine  depletion.  We  have  also  developed  two  preclinical  programs  aimed  at  maximizing  the  value  creation  potential  of  our
ERYCAPS   program,  which  we  believe  may  result  in  attractive  partnering  opportunities:  enzyme  replacement  and  immune  modulation.  As  part  of  our
value creation strategy, in June 2019, we entered into a collaboration with SQZ Biotechnologies, a cell therapy company developing novel treatments in
multiple  therapeutic  areas,  to  focus  on  the  development  of  novel  red  blood  cell-based  therapeutics  for  the  treatment  of  immuno-oncology  and  tolerance
induction.

®

®

Another  use  of  the  ERYCAPS   platform  we  are  evaluating  consists  of  deriving  extracellular  vesicules  from  red  blood  cells  that  were  loaded  with
therapeutic  compounds  (ERYCEV ).  We  successfully  produced  extracellular  vesicules  loaded  with  STING  agonists  that  exerted  measurable  in  vitro
biological effects, the results of which were presented at the annual conference of the European Red Cell Society (ERCS) in April 2022. Exosomes and
extra-cellular  vesicules  have  recently  attracted  much  attention  as  they  have  been  shown  to  transport  a  variety  of  active  cargoes  (such  as  nucleic  acids,
proteins, lipids, metabolites) from donor to recipient cells.

Corporate Information

We were incorporated in 2004. In May 2013, we completed the initial public offering of our ordinary shares on Euronext Paris. In November 2017, we
completed a global public offering, consisting of a U.S. initial public offering of American Depositary Shares, or ADSs, each representing one ordinary
share,  and  a  concurrent  private  placement  in  Europe  and  other  countries  outside  of  the  United  States  and  Canada  of  our  ordinary  shares.  Our  ordinary
shares  are  listed  on  Euronext  Paris  under  the  ticker  symbol  “ERYP”  and  our  ADSs  are  listed  on  the  Nasdaq  Global  Select  Market  under  the  symbol
“ERYP.”

4.B.2. Our Strategy

Our mission is to help patients live better, longer. Our vision is to be the leader in red blood-cell based therapeutics to treat severe forms of cancer and
orphan diseases. The key elements of our strategy to achieve this goal include the following:

45

Develop eryaspase for the treatment of oncology indications

Based  on  the  results  of  scientific  publications  and  preclinical  studies,  as  well  as  our  clinical  trials  to  date,  we  believe  that  targeting  the  asparagine
metabolism of cancer cells could potentially slow down or halt the growth of different tumor types. Based on these results, we are conducting clinical trials
and are planning to seek regulatory authorizations for eryaspase for the treatment of certain selected oncology indications. Current development tracks are
in:

• ALL: Following positive results in December 2020 of the Phase 2 clinical trial initiated and sponsored by NOPHO, we are currently evaluating the
possibility of pursuing regulatory approval in the United States based on the results of this Phase 2 trial and previous trials conducted in ALL. In
June 2021, we met with the FDA to discuss a potential BLA submission. Based on the discussions and the totality of the information available to
date,  we  believe  our  regulatory  package  can  potentially  support  an  approval  of  eryaspase  in  hypersensitive  ALL  patients.  Pending  successful
completion of remaining steps, we anticipate filing a BLA in the third quarter of 2022.

•

•

In  pancreatic  cancer:  following  the  results  of  the  TRYbeCA-1  and  rESPECT  clinical  trials  presented  at  ASCO  GI  in  January  2022,  we  are
evaluating a potential development pathway for eryaspase in pancreatic cancer. In addition, patient enrollment in the rESPECT study is continuing
at the maximum tolerated dose of 100 U/kg with a goal of enrolling a total of 18 patients.

TNBC: We launched our Phase 2 proof-of-concept clinical trial initiated in the European Union during the fourth quarter of 2018. The results from
the patients enrolled in the TRYbeCA-2 trial to date are expected to be reported around mid-2022.

Leverage our ERYCAPS  platform to develop additional innovative and novel red blood-cell based therapeutics targeting cancer and orphan diseases

®

In addition to encapsulating L-asparaginase, the active ingredient in eryaspase, we plan to leverage the broad applicability of our ERYCAPS  platform to
develop additional product candidates that use other therapeutic drug substances. We intend to continue to work on the development of our methionine
depletion program in the future, subject to future financial resources and business strategy, but are not currently devoting significant financial resources due
to other strategic priorities. We are also evaluating other cancer metabolism targeting enzymes such as arginine-deiminase. In addition to our developments
in  cancer  metabolism,  we  are  also  evaluating  other  therapeutic  approaches  such  as  cancer  immunotherapy,  enzyme  replacement  therapies  for  metabolic
diseases as well as the use of vesicles derived from red blood cells as a new approach to drug administration in view of potentially establishing partnering
options.  To  support  this  strategy,  we  intend  to  continue  to  seek  robust  worldwide  intellectual  property  protection  for  our  ERYCAPS  platform and our
resulting product candidates.

®

®

Execute on research and development and commercialization opportunities that maximize the value of our proprietary ERYCAPS  platform

®

®

We seek to maximize shareholder value from our proprietary ERYCAPS  platform technology through a combination of in-house development and well-
selected partnering opportunities in development and commercialization. In some instances, we may elect to continue development and commercialization
activities  through  the  expansion  of  our  in-house  capabilities,  but  we  will  also  evaluate  and  pursue  collaborative  arrangements  with  third  parties  for  the
development and distribution of our product candidates for specified indications and in specified territories where appropriate. The licensing agreement
signed in June 2019 with SQZ Biotechnologies for the immunomodulation therapeutic approach, as well as the conclusion of an interim supply agreement
for the clinical and commercial supply of eryaspase with Catalent, are an illustration of this strategy of creating value through partnerships. We may also
explore  co-development  or  out-licenses  of  our  platform  technology  to  third  parties  and  the  creation  of  spin-out  companies.  As  we  move  our  product
candidates  through  development  toward  regulatory  approval  in  the  United  States  and  Europe,  we  will  evaluate  several  strategic  options  to  leverage  our
ERYCAPS® platform, our development and manufacturing capabilities and our commercialization strategy through complementary assets and/or larger
transactions.  These  options  include  building  our  own  internal  sales  force  and  distribution  units  or  entering  into  collaborations  with  third  parties  for  the
distribution and marketing of approved products.

®
4.B.3. Our ERYCAPS  Platform Technology

®

Our ERYCAPS  platform uses our proprietary technology to entrap active drug substances inside red blood cells using reversible hypotonic and hypertonic
osmotic stress. Our platform technology uses transfusion-grade, standard packed red blood cells of all four blood groups (O, A, B and AB) from blood
donors which we obtain from blood banks. We match the red blood cells used to the blood type of the patient receiving treatment. To allow the therapeutic
compounds to enter into the red blood cells, we subject the red blood cells to a hypotonic solution. This causes swelling of cells and opening of pores in the
cellular membrane. At this time, therapeutic molecules can enter the red blood cells. Once the desired concentration of molecules is reached inside the red
blood cells, we subject the red blood cells to a hypertonic solution to restore the osmotic pressure to normal. This step causes water to flow out of the cell
and the pores to close, rendering the cellular membrane impermeable to molecules above a specific size, including the molecules that have been trapped
inside the cell.

46

The extent to which a red blood cell can swell, known as osmotic fragility, is not uniform and varies between packages of red blood cells. When we obtain
a package of red blood cells from a blood bank, we measure a number of key hematological parameters, including the osmotic fragility of the particular
sample. Based on the level of osmotic fragility measured, we are able to calculate the specific amount of osmotic pressure to apply in order to achieve the
desired  concentration  of  drug  substance  in  each  production  batch.  This  patent-protected  process  allows  us  to  reduce  variations  in  the  amount  of  drug
substance to be encapsulated, which ensures that quantifiable amounts of drug substance can be captured in each batch. Our expertise in understanding
osmotic fragility and optimizing the red blood cell encapsulation parameters is the cornerstone of our proprietary ERYCAPS  platform.

®

We believe that our ERYCAPS  platform technology is an innovative approach that offers several key potential benefits:

®

•

Prolonged duration of activity. Red blood cells are biocompatible carriers that have a half-life of approximately one month in the body, and this
duration  of  activity  appears  not  to  be  significantly  affected  by  our  proprietary  encapsulation  process.  This  long  half-life,  coupled  with  the
protection from the cellular membrane, allows encapsulated therapeutic drug substances to remain in the body longer, thereby increasing the
duration of their therapeutic activity and their potential efficacy with lower administration doses and fewer injections. It has been shown that the
encapsulation of L-asparaginase allows to extend its half-life from one day for free-form L-asparaginase to approximately two to three weeks
for the encapsulated form.

• Decreased risk of side effects. The red blood cell membrane protects the body from toxicities associated with the trapped drug substance, which

reduces the potential for adverse side effects from the drug.

• High reproducibility with rapid turnaround on commercial scale. Our encapsulation process is automated and is designed to produce batches
of  loaded  red  blood  cells  in  a  highly  reproducible,  reliable  and  rapid  manner.  At  our  cGMP-certified  production  facilities,  the  process  for
delivering eryaspase to patients typically takes approximately 24 hours from the start of production to delivery of the product candidate to the
hospital. We have produced over 5,500 bags of eryaspase to date for use in clinical trials, and we estimate our current expanded Lyon production
facility  and  our  interim  supply  agreement  with  Catalent  will  be  sufficient  to  establish  supply  for  our  ongoing  clinical  trials,  as  well  as
commercial needs of eryaspase, if we receive the appropriate marketing authorizations.

•

•

Stability  and  ease  of  administration.  After  manufacturing  and  release  of  the  product,  eryaspase  has  shown  to  remain  stable  for  five  days  in
refrigeration including up to six hours at room temperature. This allows hospital staff to proceed with the administration at the best time and to
maintain control of the treatment administration process

Broad applicability. Our initial efforts have focused on encapsulating enzymes, such as L-asparaginase, that deplete nutrients necessary for the
growth and proliferation of tumor cells, resulting in their starvation and death. Based on our preclinical studies and clinical experience to date,
we believe that a variety of additional therapeutic molecules can be encapsulated within red blood cells to induce tumor starvation, both for
blood cancers and solid tumors. We focus on the use of our platform in oncology, immuno-oncology and enzyme disorders.

Our intellectual property portfolio contains issued patents and patent applications in the United States and foreign countries, including 16 patent families
directed to our production process, our ERYCAPS  platform, our product candidates, methods of use and/or treatment, and related diagnostic tests. Our
core  patent  covers  eryaspase  in  the  United  States  until  the  end  of  2029,  with  potential  extension  to  the  end  of  2034,  and  in  Europe  until  2025,  with  a
potential  extension  to  2030.  We  have  exclusively  in-licensed  one  patent  family  from  Radboud  University  in  the  Netherlands  relating  to  synergistic
combinations of amino acid depletion agents.

4.B.4. Our Pipeline

4.B.5. Our Lead Product Candidate Eryaspase—A Unique Approach to Cancer Treatment

®

Eryaspase, our first product candidate developed using our proprietary ERYCAPS   platform  consists  of  the  enzyme  L-asparaginase  encapsulated  inside
erythrocytes, or red blood cells. L-asparaginase breaks down asparagine, a naturally occurring amino acid, into L-aspartic acid and ammonia. Asparagine is
naturally produced by healthy cells in the body for their own use in protein synthesis. Cancer cells also need asparagine to grow and proliferate, even more
than normal cells, but most cancer cells cannot produce enough asparagine and must rely on circulating asparagine to survive. Injection of L-asparaginase,
either by intravenous or intramuscular modes of administration, can lower asparagine levels throughout the body, thereby depriving cancer cells of a key
nutrient and causing them to starve and ultimately die. The use of L-asparaginase to deplete asparagine is a well-established treatment for ALL patients,
and in particular, pediatric ALL patients. However, important side effects including allergies, coagulation disorders, pancreatic and hepatic toxicities can
limit  treatment  compliance,  particularly  in  adults,  limiting  the  potential  use  of  current,  non-encapsulated  L-asparaginases  beyond  ALL.  We  believe  that
encapsulating L-asparaginase in red blood cells, utilizing our proprietary ERYCAPS  platform, reduce the side effects of L-asparaginase, which we believe
broadens the potential use of L-asparaginase outside the pediatric ALL setting, including for the treatment of aggressive solid and liquid tumors. Eryaspase
has been administered to more than 640 patients in clinical trials and compassionate use programs to date.

®

Eryaspase  is  administered  by  intravenous  infusion.  Once  administered,  the  red  blood  cells  containing  L-asparaginase  circulate  in  the  bloodstream  and
remove  asparagine  mainly  through  a  mechanism  of  active  transportation  of  asparagine  into  the  red  blood  cells.  Active  transporters  for  asparagine  are
present in the membrane of red blood cells. They cause normal red blood cells to contain two to three times more asparagine within the cell than in the
surrounding  plasma.  When  L-asparaginase  is  encapsulated  in  the  red  blood  cells,  it  causes  the  inner  concentration  of  asparagine  to  decrease,  which
activates the natural mechanism of the red blood cell to draw asparagine circulating in the blood plasma into the red blood cell. This asparagine is rapidly
degraded  inside  the  red  blood  cells  as  well.  When  maintained  long  enough,  this  pumping  and  degradation  activity  leads  to  a  systemic  depletion  of
asparagine levels in the bloodstream without releasing L-asparaginase into the bloodstream. The red blood cell membrane also protects the encapsulated L-
asparaginase from antibodies present in the patient’s blood that would substantially lessen or neutralize the enzyme’s activity or cause allergic reactions. As
a  result,  the  enzyme  can  remain  active  and  potentially  effective  in  the  red  blood  cell  for  a  longer  period  of  time,  while  at  the  same  time  reducing  the
potential for toxicity and related side effects. Our research indicates that the encapsulation process does not significantly alter the life span of the red blood
cell.

Eryaspase for the Treatment of Acute Lymphoblastic Leukemia (ALL)

We were previously developing eryaspase, or GRASPA , for the treatment of children and adults with ALL in combination with chemotherapy. We started
the development of eryaspase in ALL in 2005 with a Phase 1 clinical trial in patients with relapsed and refractory ALL. The clinical trial was completed in
2009. We also completed a Phase 2 study in elderly patients with ALL in 2010. We have completed five clinical trials in ALL in Europe and in the United
States in which a total of 166 patients with ALL were enrolled, of which 132 patients were treated with eryaspase.

®

Different hard-to-treat sub-indications of ALL were targeted in these trials, relapsed and refractory patients, adults and elderly patients and patients who
were allergic to other asparaginases. We believe the results of our trials support our hypothesis that encapsulation could prolong asparaginase activity and
reduce its side-effects. We also observed eryaspase to have an improved clinical benefit as compared to native L-asparaginase in our completed clinical
trials, as described below.

®
In 2014, we completed a phase 2/3 clinical trial in 80 children and adults with relapsed ALL in which we evaluated the safety and efficacy of GRASPA
compared to free-form L-asparaginase derived from the bacteria E. coli, also known as native L-asparaginase. In this European trial, patients without a
history of allergies to native L-asparaginase treatments were randomized to receive standard chemotherapy plus either GRASPA  or native L-asparaginase.
Patients with a known allergy to native L-asparaginase treatments were treated with standard chemotherapy plus GRASPA . The trial achieved both of its
primary endpoints:

®

®

•

•

Lower Incidence of Allergic Reactions. Among the non-allergic patients, none of the 26 patients treated with GRASPA experienced an allergic
reaction during the induction phase, compared to 13 patients out of 28, or 46%, of those treated with native L-asparaginase in the control group.

® 

Superior Duration of L-Asparaginase Activity. Among the non-allergic patients, the patients treated with GRASPA  maintained a mean duration
of  L-asparaginase  activity  above  100  U  per  liter  for  18.9  days,  with  at  most  two  injections  during  the  first  month  of  treatment.  This  result
compared to a mean duration of activity of 8.5 days in the control group, who received up to eight injections of native L-asparaginase.

®

51

Eryaspase or GRASPA   was  also  observed  to  have  an  improved  clinical  benefit  as  compared  to  native  L-asparaginase  based  on  its  achievement  of  the
secondary efficacy endpoints:

®

• Higher Complete Remission Rate.  At  the  end  of  the  induction  phase,  the  non-allergic  patients  in  the  GRASPA   treatment  arm,  or  76%,  had
achieved complete remission, or the disappearance of all signs of cancer in response to treatment, as compared to 46.4%, in the control arm.
®
Among the allergic patients, 60% achieved complete remission after treatment with GRASPA .

®

•

•

Improved Minimal Residual Disease Rate. Among the non-allergic patients, nine out of 26, or 35%, achieved low levels of residual leukemic
cells classified as minimal residual disease, or MRD, at the end of the induction phase, as compared to seven out of 28, or 25%, of those in the
®
control group. Among the allergic patients, six out of 26, or 23%, achieved MRD after treatment with GRASPA .

Improved  Overall  Survival  Rates.  12-month  overall  survival  rates  among  the  non-allergic  patients  treated  with  GRASPA   were  76.9%,
compared to 67.9%, for those in the control group. 12-month overall survival in the allergic group of patients was 50%. Based on three years of
follow-up, a nominal improvement of overall survival was observed (HR = 0.73).

®

®

Treatment  with  GRASPA   was  generally  well  tolerated.  Drug-related  adverse  events  generally  consisted  of  allergic  reactions,  clotting  problems,  liver
®
toxicities and pancreas disorders. None of the 52 patients receiving GRASPA  during the Phase 2/3 trial had an adverse event leading to discontinuation of
the trial, as compared to 13 out of the 28 patients, or 46%, in the control arm. A total of three patients out of the 52 patients treated with GRASPA  during
the trial experienced serious adverse events determined to be drug-related.

®

®

Based on the positive efficacy and safety results from our Phase 2/3 pivotal trial, we submitted a Marketing Authorization Application, or MAA, to the
EMA for GRASPA  for the treatment of relapsed or refractory ALL in September 2015. Following discussions with the EMA, we withdrew the MAA in
November  2016.  We  conducted  activities  designed  to  provide  data  regarding  immunogenicity  and  pharmacodynamics  of  eryaspase,  as  well  as
comparability of eryaspase produced with native versus recombinant L-asparaginase, and resubmitted an MAA in October 2017. In June 2018, based on
feedback from the EMA and FDA, it appeared that significant additional investment would be required in order to seek regulatory approval of eryaspase for
the treatment of ALL. In the context of the rapidly changing and increasingly competitive landscape with newly-approved treatment options for ALL, the
regulatory feedback and what we observed to be a limited market opportunity for eryaspase in ALL, we elected to withdraw our MAA in Relapse and
Refactory  ALL  in  the  second  half  of  2018  to  focus  our  development  efforts  on  solid  tumors.  Despite  this  shift  in  focus,  we  continue  to  support  the
investigator-sponsored trial initiated in 2017 by the Nordic Society of Pediatric Haematology and Oncology, or NOPHO to evaluate eryaspase (GRASPA®)
in ALL patients who have developed hypersensitivities to E-coli derived asparaginase. The trial protocol was amended in 2019 to increase the number of
patients to be recruited up to 50 patients. The main objectives of this trial were to evaluate the pharmacokinetic and pharmacodynamic activity, safety and
immunogenicity  profile  of  eryaspase  in  combination  with  NOPHO’s  multi-agent  chemotherapy  protocol  for  ALL,  administered  as  second-intention
treatment  for  children  or  adult  ALL  patients,  one  year  to  45  years  of  age,  who  experience  hypersensitivity  reactions  to  PEG-asparaginase  or  silent
inactivation. The study, conducted by NOPHO through 21 clinical sites in the Scandinavian and Baltic countries, included 55 patients. The enrollment has
been  completed  in  August  2020.  Preliminary  results  were  presented  in  March  2020  at  the  NOPHO  Annual  Meeting  and  final  positive  resultats  were
presented  in  December  2020  at  the  American  Society  of  Hematology  2020  Annual  Meeting.  The  primary  objectives  of  the  study  were  the  activity  and
safety  of  eryaspase.  Both  objectives  were  met.  Eryaspase  demonstrated  sustained  asparaginase  enzyme  activity  above  the  100  U/L  threshold  at  trough
levels 14 days after the first administration by 54 of 55 treated patients. Eryaspase was generally well tolerated when combined with chemotherapy, and
nearly all patients were able to receive the scheduled doses of asparaginase (median of 5 doses per patient). Of the 55 patients, only two patients had a
severe allergic reaction and discontinued eryaspase.

We are in discussions with the FDA to evaluate the possibility of pursuing regulatory approval for eryaspase in the United States in this indication based on
this IST Phase 2 clinical trial. In April 2021, we announced that we requested a pre-BLA meeting to discuss a potential BLA submission. The pre-BLA
meeting  took  place  in  June  2021.  Based  on  the  discussions  and  the  totality  of  the  information  available  to  date,  we  believe  our  regulatory  package  can
potentially support an approval of eryaspase in hypersensitive ALL patients. Pending successful completion of remaining steps, we anticipate filing a BLA
in the third quarter of 2022. In July 2021, eryaspase was granted Fast Track Designation by the FDA for the treatment of ALL patients who have developed
hypersensitivity reactions to E.coli-derived asparaginase.

Eryaspase for the Treatment of Pancreatic Cancer and Other Solid Tumors

Researchers  have  investigated  the  potential  to  target  asparagine  metabolism  in  solid  tumor  indications,  and  based  on  the  observation  that  many  solid
tumors, like lymphoblasts, lack the asparagine synthetase, or ASNS, enzyme, a rationale for the use of asparaginase in solid tumors exists. L-asparaginase
has been shown to have growth inhibitory effects in different solid tumor cell lines and in xenograft models. The toxicity profile of existing asparaginase
products has, however, been prohibitive for their use in patients. Historically, Phase 1 clinical trials conducted by researchers have been modified or halted
because of excess toxicity.

52

Completed Phase 1 Clinical Trial of Eryaspase for the Treatment of Pancreatic Cancer

In 2011, we completed an open-label Phase 1 clinical trial in 12 patients with pancreatic cancer at four sites in France. The enrolled patients were separated
into  four  cohorts  of  three  subjects  each.  Eryaspase  was  administered  as  one  injection  of  four  different  doses,  25  Units,  or  U,  per  kilogram,  50  U  per
kilogram, 100 U per kilogram or 150 U per kilogram. The primary endpoint of the trial was the determination of the maximum tolerated dose. Secondary
endpoints  included  assessments  of  safety  and  exploratory  measures  of  efficacy.  No  dose-limiting  toxicities  were  reported,  even  at  the  highest  dose
administered in the trial.

Phase 2b Clinical Trial for Eryaspase for the Treatment of Second-Line Metastatic Pancreatic Cancer

In 2014, we commenced a multi-center, open-label, randomized Phase 2b clinical trial to evaluate the efficacy of eryaspase as a second-line treatment for
patients  with  metastatic  pancreatic  cancer.  The  trial  was  conducted  at  16  sites  in  France  and  performed  in  collaboration  with  the  Groupe  Coopérateur
Multidisciplinaire en Oncologie. Professor Pascal Hammel, a gastroenterologist-oncologist at Beaujon Hospital in Paris, was the principal investigator of
the trial. The original recruitment objective was 90 patients. In February 2016, we elected to continue to enroll patients to increase the statistical power of
the trial. In September 2016, we completed enrollment of 141 patients in this trial. In March 2017, we reported positive top-line results from this trial,
which  also  included  three  data  safety  monitoring  board,  or  DSMB,  safety  reviews.  In  September  2017,  we  presented  the  full  results  of  this  trial  at  the
ESMO Congress in Madrid, Spain and the results of the trial were published in the European Journal of Cancer in November 2019.

Trial Design

In this trial, patients in the active arm were treated with eryaspase in addition to the current standard of chemotherapy, consisting of either gemcitabine or
FOLFOX, depending on which treatment the patient had received as first-line therapy. Patients in the control arm were patients treated with chemotherapy
alone. Patients were randomized at a 2:1 ratio. Prior to enrolling each patient in this trial, we used a diagnostic test to assess the level of ASNS expression
in such patient’s cancer cells. We included both patients with no or low ASNS expression levels and patients with normal or high ASNS expression levels
in the trial.

Endpoints

The co-primary endpoints of the Phase 2b clinical trial were progression-free survival, or PFS, and overall survival, or OS, rates, as measured by the hazard
ratio, or HR, for the patients that were enrolled with no or low ASNS expression levels. The HR represents the chance of events occurring in the treatment
arm relative to the chance of events occurring in the control arm. An HR of one means that there is no difference in survival between the two groups, while
an HR of greater than one or less than one means that survival was better in one of the groups. The outcome of the trial would be considered positive if the
HR was below 0.85 for the low or no ASNS expression group, irrespective of statistical significance. The secondary endpoints of the clinical trial included
overall progression-free survival and overall survival rates, as measured by HR, in the entire patient population and for the patients enrolled with normal or
high ASNS expression levels, as well as objective response rates and safety outcomes.

Efficacy Results

The primary objectives of the trial were met, with an overall survival HR of 0.65 and a progression-free survival HR of 0.72 in the patient population with
no  or  low  ASNS  expression  levels.  This  sub-group  of  the  patient  population  constituted  approximately  70%  of  the  trial  population.  There  was  also  an
overall survival benefit in the entire patient population, with a statistically significant overall survival HR of 0.60 (nominal p-value = 0.008), meaning that a
reduction in risk of death rate of 40% was observed. The PFS hazard ratio was 0.56 (nominal p-value = 0.011). The graph below shows the Kaplan-Meier
overall survival curve of the trial in the entire patient population. A Kaplan-Meier plot is a graphical statistical method commonly used to describe survival
characteristics. Similar results were observed for progression-free survival.

53

The baseline characteristics and demographics in the patient population were balanced, and overall survival and progression-free survival results appeared
to be consistent across different sub-groups, including age, gender and prior treatment.

An unexpected finding from these results was that the ASNS expression level in the patients did not appear to be predictive of treatment efficacy. However,
the ASNS expression level does appear to be a prognostic factor. Patients with high ASNS expression levels appear to have a worse prognosis, and their
relative response to eryaspase seems to be relatively higher in this group than the patients with no, low or normal ASNS expression levels. Based on this
finding, we believe future clinical trials may be conducted in the entire patient population, independent of ASNS expression levels.

Ongoing – TRYbeCA-1 Trial

Following  our  positive  Phase  2b  clinical  trial  results,  we  launched  TRYbeCA-1,  a  pivotal  Phase  3  clinical  trial  of  eryaspase  for  second-line  metastatic
pancreatic  cancer.  The  TRYbeCA-1  trial  is  evaluating  eryaspase  in  combination  with  standard  chemotherapy,  compared  to  standard  chemotherapy
(gemcitabine/nab-paclitaxel or an irinotecan-based regimen) alone, in 512 patients. Patients who met the eligibility criteria have been randomized 1-to-1 to
receive  eryaspase  in  combination  with  standard  chemotherapy  (gemcitabine/abraxane  or  irinotecan-based  regimen)  or  chemotherapy  alone  until  disease
progression.  The  primary  endpoint  is  overall  survival.  The  main  secondary  endpoints  include  progression-free  survival,  objective  response  rate,  disease
control  rate,  quality  of  life  and  safety.  Patient  enrollment  for  the  TRYbeCA-1  trial  commenced  in  September  2018  in  Europe  and  after  receipt  of  IND
approval from the FDA, we have opened clinical sites in the United States. We have obtained clinical trial authorizations in the United States and from 11
European  countries,  and  as  of  the  date  of  this  Annual  Report,  where  the  trial  has  been  conducted  in  90  clinical  trial  sites.  We  completed  enrollment  in
December 2020 with 512 randomized patients.

The interim analysis was triggered when two-thirds of the total number of events had occurred (i.e. two-thirds of the number of deaths required to make the
final analysis of the overall survival in the trial) have occurred. Those events have been reached in October 2020. We published the results from the interim
superiority analysis on February 8, 2021. This is the third review by the IDMC of the safety data of the patients enrolled and treated in the trial. The prior
reviews took place at 150, 199 and 320 patients, respectively. No safety issues were identified and the IDMC recommended that we continue the trial as
planned. Trybeca-1 has reached the 390  event required for our Final Analysis in May 2021. We have announced final results in October 2021. The trial
did not meet its primary endpoint of overall survival. The prespecified subgroup of patients treated with eryaspase and an irinotecan-based chemotherapy
demonstrated an interesting trend of survival benefit. Patients treated with eryaspase demonstrated superior disease control compared to patients treated
with  chemotherapy  only.  Other  secondary  endpoints  showed  nominal  improvement.  The  safety  profile  of  eryaspase  was  consistent  with  earlier  clinical
trials results and safety reviews. The clinical study report is currently being prepared and is expected in the first half of 2022.

th

Ongoing – rESPECT trial

rESPECT  (STUDY00002008)  is  a  proof-of-concept  investigator  initiated  Phase  1  clinical  trial  initiated  by  the  Georgetown  Lombardi  Comprehensive
Cancer Center evaluating the safety of eryaspase in combination with modified FOLFIRINOX for the treatment of first-line metastatic or locally advanced
pancreatic cancer patients. The US Food and Drug Administration (FDA) reviewed IND/Investigational New Drug application and cleared the study to
proceed  enrolling  patients  in  December  2019.  The  first  patient  was  enrolled  in  January  2021.  In  October  2021,  after  review  of  the  safety  data  of  six
additional patients comprising the second treatment cohort, we announced the determination of the maximum tolerated dose at 100 U/kg. The study has
enrolled 11 patients thus far, and is still open for enrollment with a goal of enrolling a total of 18 patients.

In  January  2022,  encouraging  data  from  the  study  were  presented  at  the  American  Society  of  Clinical  Oncology  (ASCO  GI)  Gastrointestinal  Cancers
Symposium.

Next steps in pancreatic cancer:

•

rESPECT trial: continue enrollment on rESPECT to further evaluate efficacy.

• We  will  continue  to  evaluate  the  path  forward  for  potential  further  clinical  development  focused  on  evaluating  eryaspase  in  combination  with

fluoropyrimidine-and irinotecan-based chemotherapy.

Both  the  FDA  and  the  European  Commission  have  granted  orphan  drug  designation  for  eryaspase  or  GRASPA  for the treatment of pancreatic cancer.
Orphan  drug  designation  provides  manufacturers  with  research  grants,  tax  credits  and  eligibility  for  marketing  exclusivity  of  up  to  seven  years  in  the
United States and 10 years in the European Union.

Ongoing and Planned Clinical Development in Triple Negative Breast Cancer and Other Solid Tumors

Following the results with eryaspase in the proposed treatment of second-line metastatic pancreatic cancer, we conducted a comprehensive evaluation to
determine other potential solid tumor indications and selected metastatic TNBC as the next indication to evaluate in order to expand the potential use of
eryaspase in solid tumors. TNBC is an aggressive and metabolically active form of

54

breast cancer with high rates of symptomatic metastases. TNBC cells lack expression of estrogen and progesterone receptors and do not overexpress HER2.
Scientific literature estimates that approximately 10% to 20% of the 600,000 breast cancers that are diagnosed each year in the United States and Europe in
aggregate are classified as TNBC. As commonly-utilized hormone therapy and HER2 targeting agents are not treatment options for women with TNBC,
there  is  significant  unmet  need  for  novel  therapeutic  approaches  in  this  subtype  of  breast  cancer.  At  the  end  of  2018,  we  launched  a  Phase  2  proof-of-
concept  clinical  trial  in  this  indication  in  the  European  Union,  which  we  refer  to  as  the  TRYbeCA-2  trial.  The  trial  was  open  for  enrollment  in  three
European  Union  countries  and  we  announced  enrollment  of  the  first  patient  in  June  2019.  The TRYbeCA-2 trial was designed to evaluate eryaspase in
combination with gemcitabine and carboplatine chemotherapy, compared to chemotherapy alone in approximately 64 patients, with previously untreated
metastatic TNBC. Following the negative results of the TRYbeCA-1 study announced in October 2021, we have made a strategic decision to cease further
enrollment in the TRYbeCA-2 trial. The trial had enrolled 27 patients, 26 of which had been treated. These existing patients will continue to be treated
according to the protocol of the trial. The results from these patients enrolled in the TRYbeCA-2 trial to date are expected to be reported around mid-2022.

Planned Clinical Development in Other Solid Tumors

Preclinical work is ongoing to identify other relevant solid tumor indications, including a review of the use of the product candidate in combination with
chemotherapy and immunotherapy compounds.

®
4.B.6. Other ERYCAPS  Development Programs

In addition to eryaspase, our product candidate based on L-asparaginase treatment, we believe that our ERYCAPS  platform has broad potential application
and can be used to encapsulate within red blood cells a wide range of therapeutic agents for which long-circulating therapeutic activity or rapid and specific
targeting is desired.

®

Cancer Metabolism

In addition to our product pipeline centered on L-asparaginase treatment, we are using our proprietary patent-protected ERYCAPS  platform to identify
additional  enzymes  that  could  induce  tumor  starvation.  The  TEDAC  program  intended  to  identify  additional  tumor  starvation  agents  and  to  identify
companion  diagnostic  tests.  In  preclinical  studies  performed  under  the  TEDAC  program,  we  have  identified  two  other  amino  acids,  methionine  and
arginine, and their respective enzymes, methionine-γ-lyase, or MGL, and arginine deiminase, or ADI, that we believe may be promising treatments when
encapsulated inside red blood cells.

®

Enzyme Replacement

Outside of the oncology field, we also are studying the use of our ERYCAPS  platform to promote long-acting enzyme activity.

®

Enzyme  replacement  is  a  preclinical  development  program  designed  to  use  our  proprietary  ERYCAPS   platform  for  enzyme-based  therapies  beyond
oncology. We encapsulate therapeutic enzymes inside donor-derived red blood cells using our proprietary ERYCAPS  platform in order to create product
candidates to target certain metabolic diseases. We believe that the encapsulation of the therapeutic enzymes in the red blood cells may be able to reduce
the potential for allergic reactions and to allow the therapeutic substance to remain in the body longer as compared to non-encapsulated enzymes.

®

®

Immune modulation

We  demonstrated  the  proof  of  concept  to  encapsulate  tumor  antigens  or  adjuvants  within  red  blood  cells  as  an  innovative  approach  to  cancer
immunotherapy.

Based on our preclinical research on immune modulation, we believe that encapsulated tumor antigens can be targeted to key organs, such as the spleen, in
order to induce an immune response, resulting in sustained activation of the body’s immune system to fight cancers or to tolerance induction. In preclinical
studies with three different antigens loaded in red blood cells, we have observed promising proof-of-concept data in three different tumor models. In these
studies, we observed significantly increased antigen-specific CD8+ and CD4+ T-cell responses and delays in tumor growth when the encapsulated antigens
were injected in mice with tumors, as compared to the injection of the unloaded antigens alone. As part of our value creation strategy, in 2019, we have
granted  to  SQZ  Biotechnologies  an  exclusive  worldwide  license  to  develop  antigen-specific  immune  modulating  therapies  employing  RBC-based
approaches.  Combining  SQZ’s  proprietary  and  versatile  cell  engineering  platform,  Cell  Squeeze®,  with  our  intellectual  property  related  to  RBC-based
therapeutics, rapid development of a broad pipeline of novel immunomodulatory products addressing multiple indications is envisaged.

Red blood cells derived vesicles

We  are  evaluating  deriving  extracellular  vesicules  from  red  blood  cells  loaded  with  therapeutic  compounds  (ERYCEV).  We  successfully  produced
extracellular  vesicules  loaded  with  STING  agonists  that  exerted  measurable  in  vitro  biological  effects,  the  results  of  which  have  been  presented  at  the
annual conference of the European Red Cell Society (ERCS) in April 2022. Exosomes and

55

extra-cellular  vesicules  have  recently  attracted  much  attention  as  they  have  been  shown  to  transport  a  variety  of  active  cargoes  (such  as  nucleic  acids,
proteins, lipids, metabolites) from donor to recipient cells.

4.B.7. Manufacturing and Supply

We currently operate one manufacturing facility to manufacture our product candidates for Europe which is based in Lyon, France. This production facility
complies with European cGMP. We have extended the capacity of our Lyon facility in July 2019 to ensure supply in our ongoing and future clinical trials,
as well as anticipated early commercial needs, if eryaspase is approved for marketing. We believe our current leased space is sufficient to meet our current
needs in the European Union.

For our clinical trials in the United States, we started manufacturing GMP-compliant batches out of our former manufacturing facility in Princeton, New
Jersey in the fourth quarter of 2019. This Princeton Facility was designed with the ability to scale production to supply eryaspase to meet our anticipated
clinical trial needs, including our supply requirements for U.S. patients in the ALL trial, and for our commercial needs in the United States if eryaspase is
approved. In connection with the transition to our Princeton facility, we closed our small production facility in Philadelphia, Pennsylvania in January 2020.
In April 2022, we entered into the Catalent Purchase Agreement, pursuant to which we sold to Catalent, among other things, certain assets and inventory of
materials located at the Princeton Facility for Catalent’s use in the manufacture of our lead product candidate, eryaspase. In connection therewith, we also
entered  into  an  interim  supply  agreement  with  Catalent  under  which  Catalent  agreed  to  manufacture  and  supply  us  with  eryaspase  for  our  clinical  and
commercial uses of eryaspase in the United States.

We  believe  our  production  facility  in  Lyon,  France  and  our  commercial  supply  agreement  with  Catalent  will  be  sufficient  to  supply  eryaspase  for  our
ongoing  clinical  trials  and  for  our  commercial  needs  of  eryaspase  in  the  European  Union  and  the  United  States,  in  the  event  we  receive  appropriate
marketing authorizations.

In Europe, we purchase packed red blood cells from the French Blood Agency (Ėtablissement Français du Sang). In the United States, we have supply
agreements with the American Red Cross and the New York Blood Center.

In  the  case  of  eryaspase,  we  have  the  manufacturing  and  logistics  in  place  to  deliver  eryaspase  to  patients  in  approximately  24  hours  from  the  start  of
production to delivery of the product candidate to the hospital. Once a prescription is written, we receive an order for eryaspase from the hospital. We then
source a pack of red blood cells, compatible with the patient’s blood type, from one of our partner blood banks. After identification of the key parameters of
the red blood cell unit, we encapsulate the L-asparaginase into the red blood cells using an automated process that takes three to eight hours. Before release,
the product must meet a number of quality control specifications, including the number of red blood cells in the packed product, the level of L-asparaginase
activity, the amount of extracellular L-asparaginase in the blood and the integrity of the container holding the red blood cells. We then deliver the product to
the hospital using a third-party commercial overnight delivery service. We ship the product at a refrigerated temperature of between two and eight degrees
Celsius, or approximately 36 to 46 degrees Fahrenheit. At this temperature, the product has been shown to remain stable for five days. Once removed and
ready for administration, the product remains stable for six hours at room temperature.

In May 2011, we entered into a worldwide supply agreement, as subsequently amended on April 4, 2014 and July 25, 2016, which we refer to as the 2011
Medac Agreement, under which Medac has agreed to supply us with their new, recombinant free-form L-asparaginase, called Spectrila, for which Medac
obtained a European Union marketing approval in 2016. The 2011 Medac Agreement includes an exclusivity period, starting from the date of commercial
authorization of eryaspase/GRASPA  for a duration of five years. The term of the 2011 Medac Agreement is until December 2028, provided, that Medac is
entitled, upon expiration of the five-year exclusivity period, to terminate the agreement, upon five years’ notice, in the event its supplier of the recombinant
formulation of L-asparaginase discontinues supplying to Medac. The July 2016 amendment nullified the clauses providing that we could have been forced
to  refrain  from  any  form  of  promotion  of  eryaspase/GRASPA   if  such  product  was  produced  from  a  new  formulation  of  asparaginase  registered  and
marketed prior to eryaspase/GRASPA  as a first-line treatment. We are exclusively using this new recombinant formulation of L-asparaginase in eryaspase
for new indications, including our ongoing clinical trials for pancreatic cancer, and no longer intend to use the native form of asparaginase for eryaspase.

4.B.8. Commercialization

As  we  move  our  product  candidates  through  development  toward  regulatory  approval  in  the  United  States  and  the  European  Union,  we  will  evaluate
several options for each product candidate’s commercialization strategy. These options include building our own internal sales force and distribution units
or entering into collaborations with third parties for the distribution and marketing of the approved products. We generally expect to retain commercial
rights to our product candidates, but we will also evaluate collaborative arrangements with third parties for the commercialization and distribution of our
product  candidates  for  specified  indications  and  in  specified  territories  where  appropriate.  We  previously  entered  into  collaborations  with  Teva  for  the
distribution of GRASPA  as a treatment of ALL in Israel, and with Orphan Europe, part of the Recordati Group, for the distribution of GRASPA   as  a
treatment of ALL and AML in the European Union. As a consequence of our withdrawal of the MAA for ALL and our decision to focus on solid tumors,
our agreement with Orphan Europe was terminated in the first half of 2019 without financial consequences to us. The agreement with Teva is still in effect,
but, at this time, there are no current ongoing obligations under the agreement. With the

®

®

56

exception of Israel, we have retained worldwide rights to commercialize eryaspase for the treatment of all indications, including ALL, pancreatic cancer
and TNBC. We have retained worldwide commercial rights for all of our other product candidates.

This expiration year does not take into account supplementary patent protection that could be obtained for some of our patents in the United States,
Europe, Japan and other countries. Expiration dates for U.S. patents not yet granted may be subject to patent term adjustment (PTA) and/or patent
term extension (PTE).

Of our 16 patent families, 14 patent families currently include at least one issued patent.

The term of a U.S. patent may be eligible for patent term restoration under the Hatch-Waxman Act to account for at least some of the time the drug or
method of manufacture is under development and regulatory review after the patent is granted. With regard to a drug or method of manufacture for which
FDA approval is the first permitted marketing of the active ingredient, the Hatch-Waxman Act allows for extension of the term of one U.S. patent. The
extended  patent  term  cannot  exceed  the  shorter  of  five  years  beyond  the  non-extended  expiration  of  the  patent  or  14  years  from  the  date  of  the  FDA
approval of the drug or method of manufacture. Some foreign jurisdictions have analogous patent term extension provisions that allow for extension of the
term of a patent that covers a device approved by the applicable foreign regulatory agency. In the future, if and when our product candidates receive FDA
approval, we expect to apply for patent term extensions on the patents that we believe will provide the best exclusivity position if extended.

In  addition  to  patent  protection,  we  have  trademark  protection  in  many  countries  for  our  name,  logo  and  several  product  candidates.  None  of  our
trademarks are subject to a third-party license.

Patent License from Radboud University

In 2018, we entered into an exclusive license agreement with Radboud University (the Netherlands), or Radboud, under which Radboud has granted us an
exclusive  license  to  a  patent  family,  including  a  PCT  application  filed  December  6,  2018,  directed  to  synergistic  combinations  of  amino  acid  depletion
agents, or AADA, and amino acid depletion agent sensitizers. We intend to use the patent rights licensed from Radboud to develop product candidates,
either alone or in collaboration with external partners, including product candidates that contain eryaspase as the AADA. Under the terms of the exclusive
license agreement, we may also sublicense the patent rights to external partners to generate sublicense revenue.

4.B.10. Competition

The biotechnology and pharmaceutical industries are highly competitive and subject to significant and rapid technological change as researchers learn more
about diseases and develop new technologies and treatments. Significant competitive factors in our industry include product efficacy and safety; quality
and breadth of an organization’s technology; skill of an organization’s employees and its ability to recruit and retain key employees; timing and scope of
regulatory  approvals;  government  reimbursement  rates  for,  and  the  average  selling  price  of,  products;  the  availability  of  raw  materials  and  qualified
manufacturing capacity; manufacturing costs; intellectual property and patent rights and their protection; and sales and marketing capabilities. We cannot
ensure you that any of our products that we successfully develop will be clinically superior or scientifically preferable to products developed or introduced
by our competitors.

Our competitors may also succeed in obtaining European Commission, FDA or other regulatory approvals for their product candidates more rapidly than
we are able to do, which could place us at a significant competitive disadvantage or deny us marketing exclusivity rights.

Market acceptance of our product candidates will depend on a number of factors, including:

•

•

•

•

potential advantages over existing or alternative therapies or tests;

the actual or perceived safety of similar classes of products;

the effectiveness of our sales, marketing, and distribution capabilities; and

the scope of any approval provided by the FDA, the European Commission, or foreign regulatory authorities.

Although we believe our product candidates possess attractive attributes, we cannot ensure that our product candidates will achieve regulatory or market
acceptance, or that we will be able to compete effectively in the biopharmaceutical drug markets. If our product candidates fail to gain regulatory approvals
and acceptance in their intended markets, we may not generate meaningful revenues or achieve profitability.

In  ALL  patients  who  develop  hypersensitivity  to  PEG-asparaginase,  other  forms  of  asparaginase  are  major  competitors  for  eryaspase.  These  products
include  mainly  the  free  forms  of  asparaginase  derived  from  Erwinia  Chrysanthemi  such  as  Rylaze®  and  Erwinase®/erwinaze®  marketed  by  Jazz
Pharmaceuticals  and  Clinigen  respectively.  Other  product  candidates  based  on  the  use  of  asparaginase  have  also  been  identified,  namely  products  in
preclinical  phase,  JZP341  from  Jazz  Pharmaceuticals  and  XoncaneTM,  a  biosimilar  from  the  company  Xbrane.  It  is  therefore  not  excluded  that  other
products competing with eryaspase may emerge for the treatment of ALL patients, and more specifically for the sub-population of patients hypersensitive
to PEG-asparaginase.

In  pancreatic  cancer,  eryaspase  will  be  positioned  as  an  adjunct  to  a  standard  chemotherapy  regimen.  In  pancreatic  adenocarcinoma,  chemotherapy
protocols  based  on  gemcitabine  (e.g.  gemcitabine  and  nab-paclitaxel,  Abraxane®  from  BMS)  and  fluoropyrimidine  (e.g.  FOLFIRINOX,  composed  of
fluorouracil, leucovorin, irinotecan and oxaliplatin) are standard treatments for the treatment of first-line patients with metastatic disease.

As  reported  in  October  2021,  our  Phase  3  TRYbeCA1  trial  evaluating  eryaspase  in  second-line  metastatic  pancreatic  adenocarcinoma  did  not  meet  its
primary endpoint of overall survival. A trend towards improved survival was observed in the prespecified subgroup of patients in which eryaspase was
combined with a fluoropyrimidine- and irinotecan-based regimen (including the approved liposomal formulation of irinotecan, Ipsen/Servier’s Onivyde, in
combination with flurouracil and leucovorin). The ongoing investigator sponsored Phase 1 rESPECT trial is evaluating the combination of eryaspase with
modified  FOLFIRINOX,  a  fluoropyrimidine-  and  irinotecan-based  chemotherapy  regimen  as  a  first-line  treatment  for  pancreatic  cancer  patients  with
locally advanced and metastatic disease.

If approved, we anticipate that eryaspase will be used in combination with fluoropyrimidine- and irinotecan-based regimens. We believe eryaspase has the
potential to be seen as competitive to or as a combination partner for chemotherapy agents utilized for the treatment of pancreatic cancer. Eryaspase could
potentially face competition from several investigational agents currently being evaluated in metastatic patients who have progressed on previous first-line
chemotherapy. These therapeutics include glufosfamide (Eleison Pharmaceuticals), EndoTAG-1 (SynCore Biotechnology), SM-88 (Tyme Technologies),
BL-8040  (BioLineRx),  Nan  Cancer  Vaccine  (ImmunityBio)  and  XB2001  (Xbiotech).  Drugs  currently  under  clinical  evaluation  in  combination  with
standard chemotherapies in the first-line treatment of metastatic cancer are also competitors to eryaspase. These include NIS793 (Novartis), quemliclustat
(Arcus Biosciences), zolbetuximab (Astella), pamrevlumab (FibroGen) and an electric field therapy (Novocure).

In  TNBC,  we  expect  eryaspase  to  be  used  in  combination  with  various  chemotherapy  agents  that  are  used  to  treat  metastatic  triple  negative  disease.
Eryaspase  could  potentially  face  competition  from  small  molecule  poly-ADP  ribose  polymerase  (PARP)  inhibitors,  including,  but  not  limited  to,
AstraZeneca/Merck’s  Lynparza   and  Pfizer’s  Talzenna ,  which  received  FDA  approval  for  the  treatment  of  germline  BRCA  mutant  metastatic  breast
cancer in 2018; PD-1/PD-L1 antibodies, including, but not limited to, Merck’s Keytruda  which was approved by the FDA and European Commission for
metastatic  TNBC  in  2020  and  2021  respectively  and  Roche’s  Tecentriq   which  was  approved  by  EMA  for  metastatic  TNBC  in  2019;  Trop-2  directed
antibody-drug conjugates (ADCs), including,

®

®

58

but not limited to, Gilead Science’s Trodelvy  which was approved by the FDA and European Commission for previously treated metastatic TNBC in 2020
and  2021  respectively;  and  other  compounds  in  development  such  as  ipatasertib  (Roche),  capivasertib  (AstraZeneca),  ladiaratuzumab  vedotin  (Seattle
Genetics) and trilaciclib (G1 Therapeutics).

Many of the companies against which we are competing, or against which we may compete in the future, have significantly greater financial resources and
expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved
drugs  than  we  do.  Mergers  and  acquisitions  in  the  pharmaceutical  and  biotechnology  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.

4.B.11. Government Regulation

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

U.S. Biological Product Development

In the United States, the FDA regulates biologics under the Federal Food, Drug, and Cosmetic Act, or FDCA, and the Public Health Service Act, or PHSA,
and their implementing regulations. Biologics are also subject to other federal, state and local statutes and regulations. The process of obtaining regulatory
approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial
time  and  financial  resources.  Failure  to  comply  with  the  applicable  U.S.  requirements  at  any  time  during  the  product  development  process,  approval
process or after approval, may subject an applicant to administrative or judicial sanctions. These sanctions could include, among other actions, the FDA’s
refusal  to  approve  pending  applications,  withdrawal  of  an  approval,  a  clinical  hold,  untitled  or  warning  letters,  product  recalls  or  withdrawals  from  the
market,  product  seizures,  total  or  partial  suspension  of  production  or  distribution  injunctions,  fines,  refusals  of  government  contracts,  restitution,
disgorgement, reputational harm, and/or civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us.

Our product candidates must be approved by the FDA through the Biologics License Application, or BLA, process before they may be legally marketed in
the United States. The process required by the FDA before a biologic may be marketed in the United States generally involves the following:

•

•

•

•

•

•

•

completion of extensive nonclinical, sometimes referred to as preclinical laboratory tests, preclinical animal studies and formulation studies in
accordance with applicable regulations, including the FDA’s Good Laboratory Practice, or GLP, regulations;

submission to the FDA of an IND, which must become effective before human clinical trials may begin;

performance of adequate and well-controlled human clinical trials in accordance with applicable IND and other clinical trial-related regulations,
sometimes  referred  to  as  Good  Clinical  Practices,  or  GCPs,  to  establish  the  safety  and  efficacy  of  the  proposed  product  candidate  for  its
proposed indication;

submission to the FDA of a BLA;

satisfactory completion of an FDA pre-approval inspection of the manufacturing facility or facilities where the product is produced to assess
compliance with the FDA’s cGMP requirements to assure that the facilities, methods and controls are adequate to preserve the product’s identity,
strength, quality, purity and potency;

potential FDA audit of the preclinical and clinical trial sites that generated the data in support of the BLA; and

FDA review and approval of the BLA prior to any commercial marketing or sale of the product in the United States.

The data required to support a BLA is generated in two distinct development stages: preclinical and clinical. The preclinical development stage generally
involves laboratory evaluations of drug chemistry, formulation and stability, as well as studies to evaluate toxicity in animals, which support subsequent
clinical testing. The conduct of the preclinical studies must comply with federal regulations, including GLPs. The sponsor must submit the results of the
preclinical studies, together with manufacturing information, analytical data, any available clinical data or literature and a proposed clinical protocol, to the
FDA as part of the IND. An IND is a

59

request for authorization from the FDA to administer an investigational drug product to humans. The central focus of an IND submission is on the general
investigational plan and the protocol(s) for human trials. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA raises
concerns or questions regarding the proposed clinical trials and places the IND on clinical hold within that 30-day time period. In such a case, the IND
sponsor  and  the  FDA  must  resolve  any  outstanding  concerns  before  the  clinical  trial  can  begin.  The  FDA  may  also  impose  clinical  holds  on  a  product
candidate at any time before or during clinical trials due to safety concerns or non-compliance. Accordingly, we cannot be sure that submission of an IND
will result in the FDA allowing clinical trials to begin, or that, once begun, issues will not arise that could cause the trial to be suspended or terminated.

The clinical stage of development involves the administration of the product candidate to healthy volunteers or patients under the supervision of qualified
investigators, generally physicians not employed by or under the trial sponsor’s control, in accordance with GCPs, which include the requirement that all
research subjects provide their informed consent for their participation in any clinical trial. Clinical trials are conducted under protocols detailing, among
other things, the objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria, and the parameters to be used to monitor subject
safety and assess efficacy. Each protocol, and any subsequent amendments to the protocol, must be submitted to the FDA as part of the IND. Further, each
clinical trial must be reviewed and approved by an independent institutional review board, or IRB, at or servicing each institution at which the clinical trial
will be conducted. An IRB is charged with protecting the welfare and rights of trial participants and considers such items as whether the risks to individuals
participating in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the informed consent form that
must be provided to each clinical trial subject or his or her legal representative and must monitor the clinical trial until completed.

There are also requirements governing the reporting of ongoing clinical trials and completed clinical trial results to public registries. Sponsors of clinical
trials of FDA-regulated products, including biologics, are required to register and disclose certain clinical trial information, which is publicly available at
www.clinicaltrials.gov. Information related to the product, patient population, phase of investigation, study sites and investigators, and other aspects of the
clinical  trial  is  then  made  public  as  part  of  the  registration.  Sponsors  are  also  obligated  to  discuss  the  results  of  their  clinical  trials  after  completion.
Disclosure of the results of these trials can be delayed until the new product or new indication being studied has been approved.

Clinical trials are generally conducted in three sequential phases that may overlap, known as Phase 1, Phase 2 and Phase 3 clinical trials. Phase 1 clinical
trials generally involve a small number of healthy volunteers who are initially exposed to a single dose and then multiple doses of the product candidate.
The primary purpose of these clinical trials is to assess the metabolism, pharmacologic action, side effect tolerability and safety of the product candidate
and, if possible, to gain early evidence on effectiveness. Phase 2 clinical trials typically involve studies in disease-affected patients to determine the dose
required to produce the desired benefits. At the same time, safety and further pharmacokinetic and pharmacodynamic information is collected, as well as
identification of possible adverse effects and safety risks and preliminary evaluation of efficacy. Phase 3 clinical trials generally involve large numbers of
patients  at  multiple  sites,  in  multiple  countries,  from  several  hundred  to  several  thousand  subjects,  and  are  designed  to  provide  the  data  necessary  to
demonstrate the efficacy of the product for its intended use and its safety in use, and to establish the overall benefit/risk relationship of the product and
provide  an  adequate  basis  for  product  approval.  Phase  3  clinical  trials  may  include  comparisons  with  placebo  and/or  other  comparator  treatments.  The
duration of treatment is often extended to mimic the actual use of a product during marketing. Generally, two adequate and well-controlled Phase 3 clinical
trials are required by the FDA for approval of a BLA.

Post-approval  trials,  sometimes  referred  to  as  Phase  4  clinical  trials,  may  be  conducted  after  initial  marketing  approval.  These  trials  are  used  to  gain
additional experience from the treatment of patients in the intended therapeutic indication. In some instances, FDA may provide a condition approval of a
BLA on the sponsor’s agreement to conduct additional clinical trials to further assess the biologic’s safety and effectiveness after BLA approval.

Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and written IND safety reports must be submitted
to  the  FDA  and  the  investigators  for  serious  and  unexpected  suspected  adverse  events  or  any  finding  from  tests  in  laboratory  animals  that  suggests  a
significant risk for human subjects. Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, if at all. The
FDA, the IRB, or the sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that the research subjects or
patients  are  being  exposed  to  an  unacceptable  health  risk.  Similarly,  an  IRB  can  suspend  or  terminate  approval  of  a  clinical  trial  at  its  institution  if  the
clinical trial is not being conducted in accordance with the IRB’s requirements or if the drug has been associated with unexpected serious harm to patients.
Additionally, some clinical trials are overseen by an independent group of qualified experts organized by the clinical trial sponsor, known as a data safety
monitoring board or committee. This group provides authorization for whether or not a trial may move forward at designated intervals based on access to
certain data from the trial. We may also suspend or terminate a clinical trial based on evolving business objectives and/or competitive climate. 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, must
develop methods for testing the identity, strength, quality and purity of the final product. Additionally, appropriate packaging

60

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.

BLA and FDA Review Process

Following trial completion, trial data is analyzed to assess safety and efficacy. The results of preclinical studies and clinical trials are then submitted to the
FDA as part of a BLA, along with proposed labeling for the product and information about the manufacturing process and facilities that will be used to
ensure  product  quality,  results  of  analytical  testing  conducted  on  the  chemistry  of  the  product  candidate,  and  other  relevant  information.  The  BLA  is  a
request for approval to market the biologic for one or more specified indications and must contain proof of safety, purity, potency and efficacy, which is
demonstrated by extensive preclinical and clinical testing. The application includes both negative or ambiguous results of preclinical and clinical trials, as
well as positive findings. Data may come from company-sponsored clinical trials intended to test the safety and efficacy of a use of a product, or from a
number of alternative sources, including studies initiated by investigators. To support marketing approval, the data submitted must be sufficient in quality
and quantity to establish the safety and efficacy of the investigational product to the satisfaction of the FDA. FDA approval of a BLA must be obtained
before a biologic may be offered for sale in the United States.

Under the Prescription Drug User Fee Act, or PDUFA, as amended, each BLA must be accompanied by a significant user fee, which is adjusted on an
annual basis. PDUFA also imposes an annual product fee for human drugs and an annual establishment fee on facilities used to manufacture prescription
drugs. Fee waivers or reductions are available in certain circumstances, including a waiver of the application fee for the first application filed by a small
business.

Once a BLA has been accepted for filing, which occurs, if at all, 60 days after the BLA’s submission, the FDA’s goal is to review BLAs within 10 months
of the filing date for standard review or six months of the filing date for priority review, if the application is for a product intended for a serious or life-
threatening disease or condition and the product, if approved, would provide a significant improvement in safety or effectiveness. The review process is
often significantly extended by the FDA requests for additional information or clarification.

After the BLA submission is accepted for filing, the FDA reviews the BLA to determine, among other things, whether the proposed product candidate is
safe and effective for its intended use, and whether the product candidate is being manufactured in accordance with Good Manufacturing Practice or cGMP
to  assure  and  preserve  the  product  candidate’s  identity,  strength,  quality,  purity  and  potency.  The  FDA  may  refer  applications  for  novel  drug  product
candidates  or  drug  product  candidates  which  present  difficult  questions  of  safety  or  efficacy  to  an  advisory  committee,  typically  a  panel  that  includes
clinicians and other experts, for review, evaluation and a recommendation as to whether the application should be approved and under what conditions. The
FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions. The FDA
will likely re-analyze the clinical trial data, which could result in extensive discussions between the FDA and us during the review process.

The review and evaluation of a BLA by the FDA is extensive, time consuming and may take longer than originally planned to complete, and we may not
receive a timely approval, if at all.

Before approving a BLA, the FDA will conduct a pre-approval inspection of the manufacturing facilities for the new product to determine whether they
comply  with  cGMP.  The  FDA  will  not  approve  the  product  unless  it  determines  that  the  manufacturing  processes  and  facilities  are  in  compliance  with
cGMP requirements and adequate to assure consistent production of the product within required specifications. In addition, before approving a BLA, the
FDA may also audit data from clinical trials to ensure compliance with GCP requirements. After the FDA evaluates the application, manufacturing process
and manufacturing facilities, it may issue an approval letter or a Complete Response Letter. An approval letter authorizes commercial marketing of the
product  with  specific  prescribing  information  for  specific  indications.  A  Complete  Response  Letter  indicates  that  the  review  cycle  of  the  application  is
complete and the application is not ready for approval. A Complete Response Letter usually describes all of the specific deficiencies in the BLA identified
by  the  FDA.  The  Complete  Response  Letter  may  require  additional  clinical  data  and/or  an  additional  pivotal  Phase  3  clinical  trial(s),  and/or  other
significant and time-consuming requirements related to clinical trials, preclinical studies or manufacturing. If a Complete Response Letter is issued, the
applicant  may  either  resubmit  the  BLA,  addressing  all  of  the  deficiencies  identified  in  the  letter,  or  withdraw  the  application.  Even  if  such  data  and
information is submitted, the FDA may ultimately decide that the BLA does not satisfy the criteria for approval. Data obtained from clinical trials are not
always conclusive and the FDA may interpret data differently than we interpret the same data.

There is no assurance that the FDA will ultimately approve a product for marketing in the United States, and we may encounter significant difficulties or
costs during the review process. If a product receives marketing approval, the approval may be significantly limited to specific populations, severities of
allergies, and dosages or the indications for use may otherwise be limited, which could restrict the commercial value of the product. Further, the FDA may
require  that  certain  contraindications,  warnings  or  precautions  be  included  in  the  product  labeling  or  may  condition  the  approval  of  the  BLA  on  other
changes to the proposed labeling, development of adequate controls and specifications, or a commitment to conduct post-market testing or clinical trials
and surveillance to monitor the

61

effects  of  approved  products.  For  example,  the  FDA  may  require  Phase  4  testing,  which  involves  clinical  trials  designed  to  further  assess  the  product’s
safety and effectiveness and may require testing and surveillance programs to monitor the safety of approved products that have been commercialized. The
FDA may also place other conditions on approvals including the requirement for a Risk Evaluation and Mitigation Strategy, or REMS, to assure the safe
use of the product. If the FDA concludes a REMS is needed, the sponsor of the BLA must submit a proposed REMS. The FDA will not approve the NDA
without an approved REMS, if required. A REMS could include medication guides, physician communication plans, or elements to assure safe use, such as
restricted  distribution  methods,  patient  registries  and  other  risk  minimization  tools.  Any  of  these  limitations  on  approval  or  marketing  could  restrict  the
commercial  promotion,  distribution,  prescription  or  dispensing  of  products.  Product  approvals  may  be  withdrawn  for  non-compliance  with  regulatory
standards or if problems occur following initial marketing.

Other U.S. Regulatory Matters

Manufacturing,  sales,  promotion  and  other  activities  following  product  approval  are  also  subject  to  regulation  by  numerous  regulatory  authorities  in
addition to the FDA, including, in the United States, the Centers for Medicare & Medicaid Services, or CMS, other divisions of the Department of Health
and  Human  Services,  or  HHS,  the  Drug  Enforcement  Administration,  the  Consumer  Product  Safety  Commission,  the  Federal  Trade  Commission,  the
Occupational  Safety  &  Health  Administration,  the  Environmental  Protection  Agency  and  state  and  local  governments.  In  the  United  States,  sales,
marketing and scientific or educational programs must comply with state and federal fraud and abuse laws, data privacy and security laws, transparency
laws,  and  pricing  and  reimbursement  requirements  in  connection  with  governmental  payor  programs,  among  others.  The  handling  of  any  controlled
substances must comply with the U.S. Controlled Substances Act and Controlled Substances Import and Export Act. Products must meet applicable child-
resistant packaging requirements under the U.S. Poison Prevention Packaging Act. Manufacturing, sales, promotion and other activities are also potentially
subject  to  federal  and  state  consumer  protection  and  unfair  competition  laws.  The  distribution  of  pharmaceutical  products  is  subject  to  additional
requirements and regulations, including extensive record-keeping, licensing, storage and security requirements intended to prevent the unauthorized sale of
pharmaceutical products.

The failure to comply with regulatory requirements subjects’ entities to possible legal or regulatory action. Depending on the circumstances, failure to meet
applicable  regulatory  requirements  can  result  in  criminal  prosecution,  fines  or  other  penalties,  injunctions,  recall  or  seizure  of  products,  total  or  partial
suspension  of  production,  denial  or  withdrawal  of  product  approvals,  or  refusal  to  allow  an  entity  to  enter  into  supply  contracts,  including  government
contracts. In addition, even if an entity complies with FDA and other regulatory requirements, new information regarding the safety or efficacy of a product
could lead the FDA to modify or withdraw product approval. Prohibitions or restrictions on sales or withdrawal of future products marketed by us could
materially affect our business in an adverse way.

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

U.S. Patent Term Restoration and Marketing Exclusivity

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

An abbreviated approval pathway for biological products shown to be similar to, or interchangeable with, an FDA-licensed reference biological product
was created by the BPCIA 2009. Biosimilarity, which requires that the biological product is highly similar to the reference product notwithstanding minor
differences in clinically inactive components and that there be no clinically meaningful differences between the product and the reference product in terms
of  safety,  purity,  and  potency,  can  be  shown  through  analytical  studies,  animal  studies,  and  a  clinical  trial  or  trials.  Interchangeability  requires  that  a
biological product is biosimilar to the reference product and the product can be expected to produce the same clinical results as the reference product and,
for  products  administered  multiple  times,  the  product  and  the  reference  product  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 biological product. However, complexities

62

associated with the larger, and often more complex, structure of biological products, as well as the process by which such products are manufactured, pose
significant hurdles to implementation that are still being worked out by the FDA.

A  reference  biological  product  is  granted  12  years  of  exclusivity  from  the  time  of  first  licensure  of  the  reference  product.  The  first  biological  product
submitted  under  the  abbreviated  approval  pathway  that  is  determined  to  be  interchangeable  with  the  reference  product  has  exclusivity  against  other
biologics submitting applications under the abbreviated approval pathway for the lesser of one year after the first commercial marketing, 18 months after
approval if there is no legal challenge, 18 months after the resolution in the applicant’s favor of a lawsuit challenging the biologic’s patents if an application
has been submitted, or 42 months after the application has been approved if a lawsuit is ongoing within the 42-month period.

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

European Union Drug Development

In the European Union, our product candidates may also be subject to extensive regulatory requirements. Medicinal products can only be marketed if a
marketing authorization from the competent regulatory agencies has been obtained.

The  various  phases  of  preclinical  and  clinical  research  in  the  European  Union  are  subject  to  significant  regulatory  controls.  Clinical  trials  of  medicinal
products  in  the  European  Union  must  be  conducted  in  accordance  with  European  Union  and  national  regulations  and  the  International  Conference  on
Harmonization,  or  ICH,  guidelines  on  Good  Clinical  Practices,  or  GCP.  The  Clinical  Trials  Regulation  (EU)  No  536/2014  entered  into  application  on
January  31,  2022.  The  Regulation  is  intended  to  harmonize  and  streamline  clinical  trial  authorizations,  simplify  adverse-event  reporting  procedures,
improve the supervision of clinical trials and increasing their transparency. Specifically, the new Regulation, which is directly applicable in all EU Member
States, introduces a streamlined application procedure via a single entry point, the "EU portal", the Clinical Trials Information System (CTIS); a single set
of  documents  to  be  prepared  and  submitted  for  the  application  as  well  as  simplified  reporting  procedures  for  clinical  trial  sponsors.  A  harmonized
procedure  for  the  assessment  of  applications  for  clinical  trials  has  been  introduced  and  is  divided  into  two  parts.  Part  I  is  assessed  by  the  competent
authorities of a reference member state selected by the trial sponsor largely of the type of clinical trial, risk-benefit analysis, and compliance with technical
requirements. This assessment is then submitted to the competent authorities of all the concerned member states in which the trial is to be conducted for
their review. Part II is assessed separately by the competent authorities and ECs in each EU member state concerned. Individual EU Member States shall
retain the power to authorize the conduct of clinical trials on their territory. The extent to which on-going clinical trials will be governed by the Clinical
Trials Regulation will depend on the duration of the individual clinical trial. If a clinical trial continues for more than three years from January 31, 2022 the
Clinical Trials Regulation will at that time begin to apply to the clinical trial.

European Union Marketing Authorizations

To obtain an MA for a product in the EU, an applicant must submit an MAA either under a centralized procedure administered by the EMA or one of the
procedures administered by competent authorities in the EU member states (decentralized procedure, national procedure or mutual recognition procedure).
An MA may be granted only to an applicant established in the EU.

The  centralized  procedure  provides  for  the  grant  of  a  single  MA  by  the  European  Commission  that  is  valid  for  all  EU  member  states.  Pursuant  to
Regulation  (EC)  No  726/2004,  the  centralized  procedure  is  compulsory  for  specific  products,  including  for  (i)  medicinal  products  derived  from
biotechnological processes, (ii) products designated as orphan medicinal products, (iii) advanced therapy medicinal products (ATMPs), and (iv) products
with  a  new  active  substance  indicated  for  the  treatment  of  HIV/AIDS,  cancer,  neurodegenerative  diseases,  diabetes,  auto-immune  and  other  immune
dysfunctions  and  viral  diseases.  For  products  with  a  new  active  substance  indicated  for  the  treatment  of  other  diseases  and  products  that  are  highly
innovative or for which a centralized process is in the interest of patients, the centralized procedure may be optional.

Under  the  centralized  procedure,  the  EMA’s  Committee  for  Medicinal  Products  for  Human  Use  (CHMP)  is  responsible  for  conducting  the  initial
assessment of a product. The CHMP is also responsible for several post-authorization and maintenance activities, such as the assessment of modifications
or extensions to an existing MA.

Under  the  centralized  procedure  in  the  EU,  the  maximum  timeframe  for  the  evaluation  of  an  MAA  is  210  days,  excluding  clock  stops  when  additional
information or written or oral explanation is to be provided by the applicant in response to questions of the CHMP. Accelerated assessment may be granted
by the CHMP in exceptional cases, when a medicinal product targeting an unmet medical need is expected to be of major interest from the point of view of
public health and in particular from the viewpoint of therapeutic innovation. If the CHMP accepts a request for accelerated assessment, the time limit of
210 days will be reduced to 150 days (not including clock stops). The CHMP can, however, revert to the standard time limit for the centralized procedure if
it considers that it is no longer appropriate to conduct an accelerated assessment.

63

Unlike the centralized authorization procedure, the decentralized MA procedure requires a separate application to, and leads to separate approval by, the
competent  authorities  of  each  EU  member  state  in  which  the  product  is  to  be  marketed.  This  application  is  identical  to  the  application  that  would  be
submitted to the EMA for authorization through the centralized procedure. The reference EU member state prepares a draft assessment and drafts of the
related materials within 120 days after receipt of a valid application. The resulting assessment report is submitted to the concerned EU member states who,
within 90 days of receipt, must decide whether to approve the assessment report and related materials. If a concerned EU member state cannot approve the
assessment report and related materials due to concerns relating to a potential serious risk to public health, disputed elements may be referred to the Heads
of Medicines Agencies’ Coordination Group for Mutual Recognition and Decentralised Procedures – Human (CMDh) for review. The subsequent decision
of the European Commission is binding on all EU member states.

The  mutual  recognition  procedure  allows  companies  that  have  a  medicinal  product  already  authorized  in  one  EU  member  state  to  apply  for  this
authorization to be recognized by the competent authorities in other EU member states. Like the decentralized procedure, the mutual recognition procedure
is based on the acceptance by the competent authorities of the EU member states of the MA of a medicinal product by the competent authorities of other
EU member states. The holder of a national MA may submit an application to the competent authority of an EU member state requesting that this authority
recognize the MA delivered by the competent authority of another EU member state.

In principle, an MA has an initial validity of five years in principle. The MA may be renewed after five years on the basis of a re-evaluation of the risk-
benefit balance by the EMA or by the competent authority of the EU member state in which the original MA was granted. To support the application, the
MA holder must provide the EMA or the competent authority with a consolidated version of the eCTD (Common Technical Document) providing up-to-
date  data  concerning  the  quality,  safety  and  efficacy  of  the  product,  including  all  variations  introduced  since  the  MA  was  granted,  at  least  nine  months
before  the  MA  ceases  to  be  valid.  The  European  Commission  or  the  competent  authorities  of  the  EU  member  states  may  decide,  on  justified  grounds
relating to pharmacovigilance, to proceed with one further five year renewal period for the MA. Once subsequently definitively renewed, the MA shall be
valid  for  an  unlimited  period.  Any  authorization  which  is  not  followed  by  the  actual  placing  of  the  medicinal  product  on  the  EU  market  (in  case  of
centralized procedure) or on the market of the authorizing EU member state within three years after authorization ceases to be valid (the so-called sunset
clause).

Innovative products that target an unmet medical need and are expected to be of major public health interest may be eligible for a number of expedited
development  and  review  programs,  such  as  the  Priority  Medicines,  or  PRIME,  scheme,  which  provides  incentives  similar  to  the  breakthrough  therapy
designation in the U.S. PRIME is a voluntary scheme aimed at enhancing the EMA’s support for the development of medicinal products that target unmet
medical  needs.  It  permits  increased  interaction  and  early  dialogue  with  companies  developing  promising  medicinal  products,  to  optimize  their  product
development  plans  and  speed  up  their  evaluation  to  help  the  product  reach  patients  earlier  than  normal.  Product  developers  that  benefit  from  PRIME
designation  are  potentially  eligible  for  accelerated  assessment  of  their  MAA  although  this  is  not  guaranteed.  Benefits  accrue  to  sponsors  of  product
candidates with PRIME designation, including but not limited to, early and proactive regulatory dialogue with the EMA, frequent discussions on clinical
trial designs and other development program elements, and potentially accelerated MAA assessment once a dossier has been submitted.

In the EU, a “conditional” MA may be granted in cases where all the required safety and efficacy data are not yet available. The conditional MA is subject
to conditions to be fulfilled for generating the missing data or ensuring increased safety measures. It is valid for one year and must be renewed annually
until  all  related  conditions  have  been  fulfilled.  Once  any  pending  studies  are  provided,  the  conditional  MA  can  be  converted  into  a  traditional  MA.
However, if the conditions are not fulfilled within the timeframe set by the EMA, the MA will cease to be renewed.

An  MA  may  also  be  granted  “under  exceptional  circumstances”  where  the  applicant  can  show  that  it  is  unable  to  provide  comprehensive  data  on  the
efficacy and safety under normal conditions of use even after the product has been authorized and subject to specific procedures being introduced. These
circumstances may arise in particular when the intended indications are very rare and, in the state of scientific knowledge at that time, it is not possible to
provide  comprehensive  information,  or  when  generating  data  may  be  contrary  to  generally  accepted  ethical  principles.  Like  a  conditional  MA,  an  MA
granted in exceptional circumstances is reserved to medicinal products intended to be authorized for treatment of rare diseases or unmet medical needs for
which the applicant does not hold a complete data set that is required for the grant of a standard MA. However, unlike the conditional MA, an applicant for
authorization in exceptional circumstances is not subsequently required to provide the missing data. Although the MA “under exceptional circumstances” is
granted definitively, the risk-benefit balance of the medicinal product is reviewed annually and the MA is withdrawn in case the risk-benefit ratio is no
longer favorable.

In  addition  to  an  MA,  various  other  requirements  apply  to  the  manufacturing  and  placing  on  the  EU  market  of  medicinal  products.  Manufacture  of
medicinal products in the EU requires a manufacturing authorization, and import of medicinal products into the EU requires a manufacturing authorization
allowing for import. The manufacturing authorization holder must comply with various requirements set out in the applicable EU laws, regulations and
guidance. These requirements include compliance with EU GMP standards when manufacturing medicinal products and APIs, including the manufacture
of APIs outside of the EU with the intention to import the APIs into the Union. Similarly, the distribution of medicinal products within the EU is subject to
compliance with the applicable EU laws, regulations and guidelines, including the requirement to hold appropriate authorizations for distribution granted

64

by  the  competent  authorities  of  the  EU  member  states.  MA  holders  and/or  manufacturing  and  import  authorization  (MIA)  holders  and/or  distribution
authorization holders may be subject to civil, criminal or administrative sanctions, including suspension of manufacturing authorization, in case of non-
compliance with the EU or EU member states’ requirements applicable to the manufacturing of medicinal products.

Data and Market Exclusivity

The EU provides opportunities for data and market exclusivity related to MAs. Upon receiving an MA, innovative medicinal products are generally entitled
to receive eight years of data exclusivity and 10 years of market exclusivity. Data exclusivity, if granted, prevents regulatory authorities in the EU from
referencing the innovator’s data to assess a generic application or biosimilar application for eight years from the date of authorization of the innovative
product, after which a generic or biosimilar MAA can be submitted, and the innovator’s data may be referenced. The market exclusivity period prevents a
successful  generic  or  biosimilar  applicant  from  commercializing  its  product  in  the  EU  until  10  years  have  elapsed  from  the  initial  MA  of  the  reference
product in the EU. The overall ten-year period may, occasionally, be extended for a further year to a maximum of 11 years if, during the first eight years of
those ten years, the MA 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. However, there is no guarantee that a product will be
considered by the EU’s regulatory authorities to be a new chemical/biological entity, and products may not qualify for data exclusivity.

In the EU, there is a special regime for biosimilars, or biological medicinal products that are similar to a reference medicinal product but that do not meet
the definition of a generic medicinal product. For such products, the results of appropriate preclinical or clinical trials must be provided in support of an
application for MA. Guidelines from the EMA detail the type of quantity of supplementary data to be provided for different types of biological product.

Pediatric Development

In  the  EU,  Regulation  (EC)  No  1901/2006  provides  that  all  MAAs  for  new  medicinal  products  have  to  include  the  results  of  trials  conducted  in  the
pediatric population, in compliance with a pediatric investigation plan, or PIP, agreed with the EMA’s Pediatric Committee (PDCO). The PIP sets out the
timing and measures proposed to generate data to support a pediatric indication of the medicinal product for which MA is being sought. The PDCO can
grant a deferral of the obligation to implement some or all of the measures provided in the PIP until there are sufficient data to demonstrate the efficacy and
safety of the product in adults. Further, the obligation to provide pediatric clinical trial data can be waived by the PDCO when these data are not needed or
appropriate because the product is likely to be ineffective or unsafe in children, the disease or condition for which the product is intended occurs only in
adult populations, or when the product does not represent a significant therapeutic benefit over existing treatments for pediatric patients. Once the MA is
obtained in all EU member states and study results are included in the product information, even when negative, the product is eligible for a six-month
extension to the Supplementary Protection Certificate (SPC) if any is in effect at the time of authorization or, in the case of orphan medicinal products, a
two-year extension of orphan market exclusivity.

We do not currently know whether our product candidates will need to be covered by a PIP.

Orphan Medicinal Products

Regulation  (EC)  No.  141/2000,  as  implemented  by  Regulation  (EC)  No.  847/2000  provides  that  a  medicinal  product  can  be  designated  as  an  orphan
medicinal product by the European Commission if its sponsor can establish that (1) the product is intended for the diagnosis, prevention or treatment of a
life-threatening or chronically debilitating condition; (2) either (a) such condition affects no more than five in ten thousand persons in the EU when the
application is made, or (b) the product, without the benefits derived from orphan status, would not generate sufficient return in the EU; and (3) there exists
no satisfactory method of diagnosis, prevention or treatment of the condition in question that has been authorized in the EU or, if such method exists, the
product will be of significant benefit to those affected by that condition.

In the EU, an application for designation as an orphan product can be made any time prior to the filing of the MAA. Orphan medicinal product designation
entitles an applicant to incentives such fee reductions or fee waivers, protocol assistance, and access to the centralized MA procedure. Upon grant of an
MA, orphan medicinal products are entitled to a ten-year period of market exclusivity for the approved therapeutic indication, which means that the EMA
cannot accept another MAA, or grant an MA, or accept an application to extend an MA for a similar product for the same indication for a period of ten
years. The period of market exclusivity is extended by two years for orphan medicinal products that have also complied with an agreed PIP. No extension
to any supplementary protection certificate can be granted on the basis of pediatric studies for orphan indications. Orphan medicinal product designation
does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.

The period of market exclusivity may, however, be reduced to six years if, at the end of the fifth year, it is established that the product no longer meets the
criteria on the basis of which it received orphan medicinal product destination, including where it can be demonstrated on the basis of available evidence
that  the  original  orphan  medicinal  product  is  sufficiently  profitable  not  to  justify  maintenance  of  market  exclusivity  or  where  the  prevalence  of  the
condition has increased above the threshold. Additionally, an MA may be granted to a similar medicinal product with the same orphan indication during the
10 year period if: (i) if the applicant

65

consents to a second original orphan medicinal product application, (ii) if the manufacturer of the original orphan medicinal product is unable to supply
sufficient quantities; or (iii) if the second applicant can establish that its product, although similar, is safer, more effective or otherwise clinically superior to
the original orphan medicinal product. A company may voluntarily remove a product from the register of orphan products.

Post-Approval Requirements

Where an MA is granted in relation to a medicinal product in the EU, the holder of the MA is required to comply with a range of regulatory requirements
applicable to the manufacturing, marketing, promotion and sale of medicinal products.

Similar to the United States, both MA holders and manufacturers of medicinal products are subject to comprehensive regulatory oversight by the EMA, the
European Commission and/or the competent regulatory authorities of the individual EU member states. The holder of an MA must establish and maintain a
pharmacovigilance  system  and  appoint  an  individual  qualified  person  for  pharmacovigilance  who  is  responsible  for  oversight  of  that  system.  Key
obligations include expedited reporting of suspected serious adverse reactions and submission of periodic safety update reports, or PSURs.

All new MAAs must include a risk management plan, or RMP, describing the risk management system that the company will put in place and documenting
measures to prevent or minimize the risks associated with the product. The regulatory authorities may also impose specific obligations as a condition of the
MA. Such risk-minimization measures or post-authorization obligations may include additional safety monitoring, more frequent submission of PSURs, or
the conduct of additional clinical trials or post-authorization safety studies.

In the EU, the advertising and promotion of medicinal products are subject to both EU and EU member states’ laws governing promotion of medicinal
products,  interactions  with  physicians  and  other  healthcare  professionals,  misleading  and  comparative  advertising  and  unfair  commercial  practices.
Although  general  requirements  for  advertising  and  promotion  of  medicinal  products  are  established  under  EU  directives,  the  details  are  governed  by
regulations  in  each  member  state  and  can  differ  from  one  country  to  another.  For  example,  applicable  laws  require  that  promotional  materials  and
advertising  in  relation  to  medicinal  products  comply  with  the  product’s  Summary  of  Product  Characteristics,  or  SmPC,  as  approved  by  the  competent
authorities  in  connection  with  an  MA.  The  SmPC  is  the  document  that  provides  information  to  physicians  concerning  the  safe  and  effective  use  of  the
product. Promotional activity that does not comply with the SmPC is considered off-label and is prohibited in the EU. Direct-to-consumer advertising of
prescription medicinal products is also prohibited in the EU.

If  we  fail  to  comply  with  applicable  foreign  regulatory  requirements,  we  may  be  subject  to,  among  other  things,  fines,  suspension  or  withdrawal  of
regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

Other European Regulatory Matters

French Regulatory Framework

France: Clinical trials

General framework:  In  the  European  Union,  the  Clinical  Trials  Regulation  (EU)  No  536/2014,  which  entered  into  application  on  January  31,  2022,
harmonizes  and  streamlines  clinical  trial  authorizations,  simplify  adverse-event  reporting  procedures,  improve  the  supervision  of  clinical  trials  and
increasing their transparency in all EU Member States, including France.

In  France,  for  example,  Directive  No.  2001/20/EC  has  been  implemented  by  Law  2004-806  of  August  9,  2004  regarding  the  public  health  policy  and
Decree 2006-477 of April 26, 2006, modifying the section of the Public Health Code, or PHC, on biomedical research. The Act of August 9, 2004 was
notably amended by Law No. 2012-300 of March 5, 2012, or the “Loi Jardé,” related to biomedical research involving human subjects, and French Order
No.  2016-800  of  June  16,  2016  related  to  clinical  trials  of  medicinal  products  for  human  use,  which  adapted  French  law  to  the  new  provisions  of
Regulation No. 536/2014 of the European Parliament and of the Council of April 16, 2014 related to clinical trials of medicinal products for human use,
which repealed Directive 2001/20/EC. The Jardé Act was inapplicable for a long time, and applicable since November 18, 2016, date of its enforcement
decree.

This Act specifies the modalities for carrying out research involving the human person. In particular, it specifies the definitions applicable to the various
categories of research falling within its scope, the operation of the committees for the protection of persons (CPP), the procedures for requesting an opinion
from the CPP and authorization from the ANSM, as well as the rules applicable to vigilance.

Applicable provisions: French Act No. 2012-300 of March 5, 2012, or the “Loi Jardé” related to research involving the human person, and French Order
No. 2016-800 of 16 June 2016 related to research involving the human person have adapted French law to the new provisions of Regulation No. 536/2014.
Article  L.  1121-4  and  L.  1123-8  PHC  currently  in  force  (as  amended  by  Law  2004-806,  Law  2012-300  Order  2016-800),  establishes  a  system  of  prior
authorization for interventional clinical trials only. This

66

authorization  is  granted  by  the  French  Medicines  Agency,  or  ANSM.  The  conduct  of  all  clinical  trials  (interventional  or  not)  also  requires  a  favorable
opinion of the competent Ethics Committee (Comité de protection des personnes – CPP).

Ethics Committee assessment: Under Article L. 1123-7 of the PHC, the competent Ethics Committee—selected randomly by drawing lots under Article
L.  1123-6  of  the  PHC—shall  notably  assess  whether  the  conditions  in  which  the  trial  will  be  conducted  are  valid.  This  assessment  should  be  based  on
whether:  adequate  protection  is  offered  to  individuals,  in  particular  to  participants;  adequate  information  is  provided  to  the  participants  and  appropriate
procedure is in place to obtain their informed consent; the project is relevant; the benefits/risks assessment is satisfactory; the objectives of the trial are
adequate  to  the  means  implemented;  the  qualification  of  the  investigator(s)  is  satisfactory;  the  conditions  and  amount  of  patients’  remuneration  is
compliant; and the method for recruiting participants is adequate.

ANSM authorization: The ANSM, after submission of the complete file containing not only information on the clinical protocol, but also specific product
data  and  its  quality  control,  as  well  as  results  of  preclinical  studies,  may  inform  the  sponsor  that  it  objects  to  the  implementation  of  the  research.  The
sponsor can then modify the contents of its research project and submit this amended or supplemented request to the ANSM. If the sponsor does not alter
the  content  of  its  request,  the  request  is  considered  rejected.  Under  Article  R.  1123-38  of  the  PHC,  the  time  limit  for  the  examination  of  a  request  for
authorization cannot exceed 60 days from the receipt of the complete file. Under Article L. 1123-11 of the PHC, in the event of risk to public health or if
the  ANSM  considers  that  the  conditions  in  which  the  research  is  implemented  no  longer  correspond  to  the  conditions  indicated  in  the  request  for
authorization or does not comply with the provisions of the Public Health Code, it may at any time request changes to procedures for the realization of
research, and suspend or ban this research.

The decision of the ANSM of November 24, 2006 sets the rules for Good Clinical Practice, or GCPs, for clinical trials on medicines for human use as
referred to in Article L. 1121-3 of the PHC. GCPs aim to ensure both the reliability of data arising from clinical trials and the protection of the persons
participating  in  these  clinical  trials.  GCPs  apply  to  all  clinical  trials,  including  pharmacokinetics,  bioavailability  and  bioequivalence  studies  in  healthy
volunteers as well as Phase 2 to Phase 4 clinical trials.

Depending  of  the  type  of  personal  data  processing  carried  out  during  clinical  trials  and  the  nature  of  such  trials,  it  might  be  necessary  to  carry  out
formalities by the French Data Protection Authority, or the CNIL. The sponsor of the trial might have to file with the CNIL a compliance undertaking with
one of CNIL's reference methodologies through a simplified notification procedure or file for a request of authorization. Patients then always shall have a
right  to  access  and  correct  their  personal  data,  and  to  object  to  their  processing/withdraw  their  consent,  require  their  deletion  or  a  limitation  of  the
processing pursuant to the GDPR.

The  main  French  legislative  and  regulatory  texts  relating  to  the  conduct  of  clinical  trials  have  been  largely  codified  in  the  French  Public  Health  Code
(Articles L. 1121-1 to L. 1126-12 and Articles R. 1121-1 to R. 1125-26 in particular, govern clinical trials involving human beings) and include:

•

Law No. 2018-493 of June 20, 2018 on the protection of personal data.

Protection of Clinical Trial Subjects

Under  French  law  (Article  L.  1121-2  PHC),  a  clinical  trial  may  be  undertaken  only  if  (i)  it  is  based  on  the  latest  stage  of  scientific  knowledge  and  on
sufficient preclinical testing, (ii) the foreseeable risk incurred by the subjects is outweighed by the benefit expected for these persons or the interest of the
research,  (iii)  it  aims  at  expanding  scientific  knowledge  and  the  means  possible  to  improve  the  human  condition  and  (iv)  the  research  was  designed  to
reduce the pain, inconveniences, fear and other predictable inconvenience connected to the disease or to the research, by taking into account in particular
the degree of maturity of minors and the capacity of understanding of adults unable to express an informed consent. All these conditions must be fulfilled
in order to start a clinical trial.

67

A  clinical  trial  (Article  L.  1121-3  PHC)  may  be  undertaken  under  the  following  technical  conditions:  (a)  under  the  direction  and  the  supervision  of  a
qualified  physician  and  (b)  under  adapted  material  and  technical  conditions,  compatible  with  the  rigorous  imperatives  of  science  and  the  safety  of  the
clinical trial subjects.

Two documents must be provided to clinical trial subjects before the conduct of the trial. First, the patient must receive a patient information sheet which
must contain in particular a description of the objective, the methodology and the time period of the research, as well as a description of the alternative
treatments, the number of subjects expected to take part in the study, the anticipated benefits, the constraints and the foreseeable risks resulting from the
administration of the products that are the object of the clinical trials but also the favorable opinion of the ethics committee and the authorization of the
ANSM, and information on processing of personal data. The information communicated must be summarized in a written document delivered to the patient
prior to any administration of products by the investigator or a physician (Article L. 1122-1 PHC).

Second, the patient must confirm his or her agreement to participate in the clinical study by signing an informed consent form (Article L. 1122-1-1 PHC).
For each study, patient information must include a right to refuse to participate and to withdraw consent at any time and by any means without further
consequences or prejudice. A clinical trial on a minor may be undertaken only if, in particular, the informed consent of the parents or legal representative
has been obtained. Furthermore, a clinical trial on adults under guardianship requires the informed consent of the adult’s legal representative.

Responsibility of the sponsor and insurance obligation of the sponsor

The sponsor shall indemnify the subject of the trial in case of damage arising as a consequence of the research, unless he proves that the damage does not
result from his fault or the fault of any other person intervening in the trial (Article L.1121-10 PHC). The sponsor must have an insurance covering its civil
liability and the liability of any person intervening in the research, for any damage arising from the trial for a minimum of 10 years as of the end of the trial
(Article L.1121-10 PHC).

Under French law, the State is responsible for compensating the damage resulting from a medical accident occurring during a clinical trial in the event of
no fault, i.e. in the event of a medical accident for which no fault is found. In this respect, a mechanism provides for compensation by the National Office
for Medical Accidents (Office national des accidents médicaux), as part of national solidarity.

France: Post-marketing requirements

Any  pharmaceutical  product  distributed  in  France  will  be  subject  to  pervasive  and  continuing  regulation  by  the  ANSM,  including,  among  other  things,
record-keeping  requirements,  reporting  of  adverse  experiences  with  the  product,  providing  updated  safety  and  efficacy  information,  distribution
requirements,  complying  with  promotion  and  advertising  requirements.  French  law  strictly  regulates  labeling,  advertising,  promotion  and  other  types  of
information on products that are placed on the market and imposes requirements and restrictions on drug manufacturers, such as those related to direct-to-
consumer advertising, the prohibition on promoting products for uses or in patient populations that are not described in the product’s approved labeling
(known as “off-label use”), industry-sponsored scientific and educational activities.

Failure to comply with the applicable regulatory requirements may result in restrictions on the marketing of a product or withdrawal of the product from the
market as well as possible administrative or criminal sanctions.

France: Declaration of Financial Interests

“Transparency”  or  “French  Sunshine  Act”:  The  French  Public  Health  Code  (PHC)  contains  certain  provisions  regarding  transparency  of  fees  and
rewards received by some healthcare professionals from industries, i.e. companies manufacturing or marketing health products, resulting from an Act No.
2011-2012 of December 29, 2011, amended by an Act No. 2016-41 of 26 January 2016, and corresponding implementing decrees. It results from these
provisions (Article L.1453-1 and D. 1453-1 and seq. PHC) that companies manufacturing or marketing healthcare products (medicinal products, medical
devices, etc.) in France shall publicly disclose (on a specific public website available at: https://www.entreprises-transparence.sante.gouv.fr) the advantages
and  fees  paid  to  healthcare  professionals  amounting  to  10  euros  or  above,  as  well  as  the  agreements  concluded  with  the  latter,  along  with  detailed
information about each agreement (the precise subject matter of the agreement, the date of signature of the agreement, its end date, the total amount paid to
the healthcare professional, etc.).

“Anti-gift”: The French Public Health Code also contains “anti-gift” provisions setting out a general prohibition of payments and rewards from industries,
i.e. companies manufacturing or marketing health products, to healthcare professionals, with limited exceptions and strictly defines the conditions under
which such payments or rewards are lawful. The provisions resulting from an Act No. 2011-2012 were amended by an Order No. 2017-49 of January 19,
2017 ratified by the Law 2019-774 of July 24, 2019 which notably extended their application to a broader range of legal and physical persons - including
social media influencers, specified the scope of the operations excluded from the prohibition and those authorized under some conditions, and provided for
a new authorization process. The changes of the “anti-gift” rules were aimed to enter into force on a date provided by decree or, at the latest, on July 1,
2018. In the absence of implementing texts to date, the new provisions (Articles L. 1453-3 to L. 1453-14 PHC) entered into

68

force on July 1, 2018. A decree of August 7, 2020 sets out the amounts for which the benefit, depending on the benefit provided, is considered negligible
and  does  not  require  any  declaratory  action.  A  second  decree  of  August  7,  2020  defines  the  amounts  above  which  the  agreement  is  subject  to  an
authorization  regime,  with  amounts  less  than  or  equal  to  these  amounts  requiring  a  simple  declaration.  The  decree  also  provide  with  the  declaration
schedule to the competent authority.

French Pharmaceutical Company Status

We  have  the  regulated  status  of  pharmaceutical  manufacturing  establishment,  which  allows  us  to  manufacture  our  product  candidates.  Obtaining  a
pharmaceutical manufacturing establishment license, either as a distributor or as a manufacturer requires the submission of an application dossier to the
ANSM. The application package will vary depending on the type of application (distribution license or manufacturing license). The ANSM grants such
license after verifying that the company has adequate premises, the necessary personnel and adequate procedures to carry out the proposed pharmaceutical
activities.

Reimbursement and Health Reform

®

Significant uncertainty exists as to the coverage and reimbursement status of any product candidates for which we obtain regulatory approval. In the case of
GRASPA , we have entered into distribution arrangements with Orphan Europe and Teva for marketing in Europe and Israel, respectively, and those third
parties  will  be  responsible  for  obtaining  coverage  and  reimbursement  for  GRASPA   in  those  territories  if  it  is  approved.  Our  agreement  with  Orphan
Europe was terminated in the first half of 2019 without financial consequences to us. The agreement with Teva is still in effect, but, at this time, there are
no current ongoing obligations under the agreement. Sales of our products will depend, in part, on the extent to which our products, once approved, will be
covered and reimbursed by third-party payors, such as government health programs, commercial insurance and managed healthcare organizations. These
third-party payors are increasingly reducing reimbursement levels for medical products and services. The process for determining whether a third-party
payor  will  provide  coverage  for  a  drug  product  typically  is  separate  from  the  process  for  setting  the  price  of  a  drug  product  or  for  establishing  the
reimbursement rate that a payor will pay for the drug product once coverage is approved. Third-party payors may limit coverage to specific drug products
on an approved list, also known as a formulary, which might not include all of the approved drugs for a particular indication.

®

To secure coverage and reimbursement for any product candidate that might be approved for sale, we may need to conduct expensive pharmacoeconomic
studies  in  order  to  demonstrate  the  medical  necessity  and  cost-effectiveness  of  the  product  candidate,  in  addition  to  the  costs  required  to  obtain  FDA,
European Commission, or other comparable regulatory approvals. Whether or not we conduct such studies, our product candidates may not be considered
medically necessary or cost-effective. A third-party payor’s decision to provide coverage for a drug product does not imply that an adequate reimbursement
rate will be approved. Further, one payor’s determination to provide coverage for a product does not assure that other payors will also provide coverage,
and adequate reimbursement, for the product. Third-party reimbursement may not be sufficient to enable us to maintain price levels high enough to realize
an appropriate return on our investment in product development.

The containment of healthcare costs has become a priority of federal and state governments, and the prices of drugs have been a focus in this effort. The
U.S. government, state legislatures and foreign governments have shown significant interest in implementing cost-containment programs, including price
controls, restrictions on reimbursement, utilization management and requirements for substitution of generic products. Adoption of price controls and cost-
containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit our net revenue and
results. Decreases in third-party reimbursement for our product candidates or a decision by a third-party payor to not cover our product candidates could
reduce physician usage of the product candidates and could have a material adverse effect on our sales, results of operations and financial condition.

For  example,  the  ACA  has  already  had,  and  is  expected  to  continue  to  have,  a  significant  impact  on  the  health  care  industry.  The  ACA  has  expanded
coverage for the uninsured while at the same time containing overall healthcare costs. With regard to pharmaceutical products, among other things, the
ACA  expanded  and  increased  industry  rebates  for  drugs  covered  under  Medicaid  programs  and  made  changes  to  the  coverage  requirements  under  the
Medicare Part D program, there have been judicial and Congressional challenges to certain aspects of the ACA. For example, since January 2017, former
President Trump signed several Executive Orders and other directives designed to delay the implementation of certain provisions of the ACA or otherwise
circumvent some of the requirements for health insurance mandated by the ACA. Concurrently, Congress considered legislation that would repeal or repeal
and replace all or part of the ACA. While Congress has not passed comprehensive repeal legislation, several bills affecting the implementation of certain
taxes  under  the  ACA  have  been  signed  into  law.  The  Tax  Act  included  a  provision  which  repealed,  effective  January  1,  2019,  the  tax-based  shared
responsibility  payment  imposed  by  the  ACA  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.”  The  2020  federal  spending  package  permanently  eliminated,  effective  January  1,  2020,  the  ACA-
mandated “Cadillac” tax on high-cost employer-sponsored health coverage and medical device tax and, effective January 1, 2021, also eliminates the health
insurer tax. Further, the BBA, among other things, amended the ACA, effective January 1, 2019, to increase from 50 percent to 70 percent the point-of-sale
discount that is owed by pharmaceutical manufacturers who participate in Medicare Part D and to close the coverage gap in most Medicare drug plans,
commonly referred to as the “donut hole.” For example, on June 17, 2021 the U.S. Supreme Court dismissed a

69

challenge on procedural grounds that argued the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. Thus,
the ACA will remain in effect in its current form. Further, prior to the U.S. Supreme Court ruling, on January 28, 2021, President Biden issued an executive
order to initiate a special enrollment period for purposes of obtaining health insurance coverage through the ACA marketplace. The executive order also
instructs certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others,
reexamining  Medicaid  demonstration  projects  and  waiver  programs  that  include  work  requirements,  and  policies  that  create  unnecessary  barriers  to
obtaining access to health insurance coverage through Medicaid or the ACA. It is unclear how any such challenges and the healthcare reform measures of
the Biden administration will impact ACA.

In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted. For example, on August 2, 2011,
the Budget Control Act of 2011 among other things, created measures for spending reductions by Congress. Specifically, the Joint Select Committee on
Deficit  Reduction  was  created  to  recommend  to  Congress  proposals  in  spending  reductions.  The  Joint  Select  Committee  on  Deficit  Reduction  did  not
achieve  a  targeted  deficit  reduction  of  at  least  $1.2  trillion  for  the  years  2012  through  2021,  thereby  triggering  the  legislation’s  automatic  reduction  to
several government programs. This includes aggregate reductions to Medicare payments to providers of up to 2% per fiscal year, started in April 2013 and
which, due to subsequent legislative amendments, will stay in effect through 2031 unless additional Congressional action is taken. However, COVID-19
relief support legislation suspended the 2% Medicare sequester from May 1, 2020 through March 31, 2022. Under current legislation, the actual reduction
in Medicare payments will vary from 1% in 2022 to up to 3% in the final fiscal year of this sequester. On March 11, 2021, President Biden signed the
American  Rescue  Plan  Act  of  2021  into  law,  which  eliminates  the  statutory  Medicaid  drug  rebate  cap,  currently  set  at  100%  of  a  drug’s  average
manufacturer price, for single source and innovator multiple source drugs, beginning January 1, 2024. Additionally, on January 2, 2013, President Obama
signed  into  law  the  American  Taxpayer  Relief  Act  of  2012,  which,  among  other  things,  reduced  Medicare  payments  to  several  providers,  including
hospitals,  imaging  centers  and  cancer  treatment  centers,  and  increased  the  statute  of  limitations  period  for  the  government  to  recover  overpayments  to
providers from three to five years.

Recently, there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products. Such scrutiny
has resulted in several recent U.S. Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring
more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, reduce the cost of drugs under Medicare
and reform government program reimbursement methodologies for drug products. At the federal level, the Trump administration used several means to
propose implementing drug pricing reform, including through federal budget proposals, executive orders and policy initiatives. For example, on July 24,
2020 and September 13, 2020, the Trump administration announced several executive orders related to prescription drug pricing that seek to implement
several of the administration’s proposals. As a result, the FDA released a final rule and guidance on September 24, 2020, providing pathways for states to
build and submit importation plans for drugs from Canada. Further, on November 20, 2020, HHS finalized a regulation removing safe harbor protection for
price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit managers, unless the price
reduction is required by law. The implementation of the rule has been delayed by the Biden administration from January 1, 2022 to January 1, 2023 in
response to ongoing litigation. The rule also creates a new safe harbor for price reductions reflected at the point-of-sale, as well as a safe harbor for certain
fixed fee arrangements between pharmacy benefit managers and manufacturers , the implementation of which have also been delayed pending review by
the Biden administration until January 1, 2023. On November 20, 2020, CMS issued an interim final rule implementing President Trump’s Most Favored
Nation executive order, which would tie Medicare Part B payments for certain physician-administered drugs to the lowest price paid in other economically
advanced countries. As a result of litigation challenging the Most Favored Nation model, on December 27 2021, CMS published a final rule that rescinded
the  Most  Favored  Nation  model  interim  final  rule.  In  July  2021,  the  Biden  administration  released  an  executive  order,  “Promoting  Competition  in  the
American Economy,” with multiple provisions aimed at prescription drugs. In response to Biden’s executive order, on September 9, 2021, HHS released a
Comprehensive Plan for Addressing High Drug Prices that outlines principles for drug pricing reform and sets out a variety of potential legislative policies
that  Congress  could  pursue  to  advance  these  principles.  No  legislation  or  administrative  actions  have  been  finalized  to  implement  these  principles.  In
addition, Congress is considering drug pricing as part of other reform initiatives. At the state level, legislatures have increasingly passed legislation and
implemented  regulations  designed  to  control  pharmaceutical  and  biological  product  pricing,  including  price  or  patient  reimbursement  constraints,
discounts,  restrictions  on  certain  product  access  and  marketing  cost  disclosure  and  transparency  measures,  and,  in  some  cases,  designed  to  encourage
importation from other countries and bulk purchasing.

We expect that additional federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state
governments will pay for healthcare products and services, and in turn could significantly reduce the projected value of certain development projects and
reduce our profitability. Further, it is possible that additional action is taken in response to the COVID-19 pandemic.

In addition, in some foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing
drug  pricing  vary  widely  from  country  to  country.  For  example,  the  European  Union  provides  options  for  its  Member  States  to  restrict  the  range  of
medicinal products for which their national health insurance systems provide reimbursement

70

and to control the prices of medicinal products for human use. A Member State may approve a specific price for the medicinal product or it may instead
adopt  a  system  of  direct  or  indirect  controls  on  the  profitability  of  the  company  placing  the  medicinal  product  on  the  market.  For  example,  in  France,
effective  market  access  will  be  supported  by  agreements  with  hospitals  and  products  may  be  reimbursed  by  the  Social  Security  Fund.  The  price  of
medicines is negotiated with the Economic Committee for Health Products, or CEPS. There can be no assurance that any country that has price controls or
reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements for any of our product candidates.

Historically,  products  launched  in  the  European  Union  do  not  follow  price  structures  of  the  United  States  and  generally  prices  tend  to  be  significantly
lower.  In  the  EU  some  countries  may  require  the  completion  of  additional  studies  that  compare  the  cost-effectiveness  of  a  particular  medicinal  product
candidate to currently available therapies. This Health Technology Assessment, or HTA process, which is currently governed by the national laws of the
individual EU Member States, is the procedure according to which the assessment of the public health impact, therapeutic impact and the economic and
societal  impact  of  use  of  a  given  medicinal  product  in  the  national  healthcare  systems  of  the  individual  country  is  conducted.  The  outcome  of  HTA
regarding  specific  medicinal  products  will  often  influence  the  pricing  and  reimbursement  status  granted  to  these  medicinal  products  by  the  competent
authorities of individual EU Member States. On January 31, 2018, the European Commission adopted a proposal for a regulation on health technologies
assessment. The proposed regulation is intended to boost cooperation among EU Member States in assessing health technologies, including new medicinal
products,  and  providing  the  basis  for  cooperation  at  EU  level  for  joint  clinical  assessments  in  these  areas.  In  December  2021  the  HTA  Regulation  was
adopted and entered into force on 11 January 2022. It will apply from 2025.

Other Healthcare Laws and Compliance Requirements

Our  business  operations  in  the  United  States  and  our  arrangements  with  clinical  investigators,  healthcare  providers,  consultants,  third  party  payors  and
patients may expose us to broadly applicable federal and state fraud and abuse and other healthcare laws. These laws may impact, among other things, our
research, proposed sales, marketing and education programs of our product candidates that obtain marketing approval. The laws that may affect our ability
to operate include, among others:

•

•

the  U.S.  federal  Anti-Kickback  Statute,  which  prohibits,  among  other  things,  persons  and  entities  from  knowingly  and  willfully  soliciting,
receiving,  offering  or  paying  remuneration  (including  any  kickback,  bribe  or  rebate),  directly  or  indirectly,  in  cash  or  in  kind,  to  induce  or
reward, or in return for, either the referral of an individual for, or the purchase, lease, order, or recommendation of, an item, good, facility or
service reimbursable under a federal healthcare program, such as the Medicare and Medicaid programs;

the U.S. federal civil and criminal false claims laws, including the civil False Claims Act, which can be enforced by individuals, on behalf of the
government through civil whistleblower or qui tam actions, and civil monetary penalty laws prohibits individuals and entities from, among other
things, knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other third-party payors that are false
or fraudulent, or making a false statement or record material to payment of a false claim or avoiding, decreasing, or concealing an obligation to
pay money to the federal government, including for example, providing inaccurate billing or coding information to customers or promoting a
product off-label;

• HIPAA, which created additional federal, civil and criminal statutes that prohibit knowingly and willfully executing or attempting to execute a
scheme to defraud any healthcare benefit program, knowingly and willfully embezzling or stealing from a healthcare benefit program, willfully
obstructing a criminal investigation of a healthcare offense, and knowingly and willingly falsifying, concealing or covering up a material fact or
making materially false statements, fictitious, or fraudulent statements in connection with the delivery of or payment for healthcare benefits,
items, or services;

•

the federal Physician Payments Sunshine Act, enacted as part of the ACA, which requires applicable manufacturers of drugs, devices, biologics
and  medical  supplies  for  which  payment  is  available  under  Medicare,  Medicaid,  or  the  Children’s  Health  Insurance  Program,  with  specific
exceptions,  to  track  and  annually  report  to  CMS  payments  and  other  transfers  of  value  provided  to  physicians  (defined  to  include  doctors,
dentists,  optometrists,  podiatrists  and  chiropractors),  other  healthcare  professionals  (such  as  physician  assistants  and  nurse  practitioners)  and
teaching hospitals, as well as certain ownership and investment interests held by physicians or their immediate family members;

• HIPAA,  as  amended  by  HITECH,  and  their  implementing  regulations,  which  imposes  certain  requirements  on  covered  entities,  and  their
business associates that perform functions or activities that involve individually identifiable health information on their behalf as well as their
covered subcontractors, relating to the privacy, security and transmission of individually identifiable health information; and

•

State and/or foreign equivalents of each of the above federal laws and regulations, such as: state anti-kickback and false claims laws which may
apply  to  items  or  services  reimbursed  by  any  third-party  payor,  including  commercial  insurers;  state  marketing  and/or  transparency  laws
applicable to manufacturers that may be broader in scope than the federal requirements; state laws that require biopharmaceutical companies to
comply  with  the  biopharmaceutical  industry’s  voluntary  compliance  guidelines  and  the  relevant  compliance  guidance  promulgated  by  the
federal government; state laws

71

that  require  drug  manufacturers  to  report  information  related  to  payments  and  other  transfers  of  value  to  physicians  and  other  healthcare
providers, marketing expenditures, or drug pricing; state and local laws that require the registration of pharmaceutical sales representatives; and
state  and/or  foreign  laws  governing  the  privacy  and  security  of  health  information  in  certain  circumstances,  many  of  which  differ  from  each
other in significant ways and may not have the same effect as HIPAA, thus complicating compliance efforts.

The  ACA  broadened  the  reach  of  the  federal  fraud  and  abuse  laws  by,  among  other  things,  amending  the  intent  requirement  of  the  U.S.  federal  Anti-
Kickback Statute and certain federal criminal healthcare fraud statutes. Pursuant to the statutory amendment, a person or entity no longer needs to have
actual  knowledge  of  those  statutes  or  specific  intent  to  violate  them  in  order  to  have  committed  a  violation.  In  addition,  the  ACA  provides  that  the
government may assert that a claim including items or services resulting from a violation of the U.S. federal Anti-Kickback Statute constitutes a false or
fraudulent claim for purposes of the civil False Claims Act or the civil monetary penalties statute.

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws will involve substantial costs. It is possible
that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving
applicable  fraud  and  abuse  or  other  healthcare  laws.  If  our  operations  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, for example, significant administrative, civil, and criminal penalties, damages, fines, disgorgement,
contractual  damages,  reputational  harm,  diminished  profits  and  future  earnings,  imprisonment,  exclusion  from  government  funded  healthcare  programs,
such  as  Medicare  and  Medicaid,  additional  reporting  requirements  and  oversight  if  we  become  subject  to  a  corporate  integrity  agreement  or  similar
agreement  to  resolve  allegations  of  non-compliance  with  these  laws  and  the  curtailment  or  restructuring  of  our  operations.  If  the  physicians  or  other
healthcare  providers  or  entities  with  whom  we  expect  to  do  business  are  found  to  be  not  in  compliance  with  applicable  laws,  they  may  be  subject  to
significant administrative, civil, and criminal sanctions, including exclusions from government funded healthcare programs.

4.C.Organizational Structure.

The following diagram illustrates our corporate structure:

4.D.Property, Plants and Equipment.

Our principal executive offices are located at 60 Avenue Rockefeller, 69008 Lyon, France. We lease office and laboratory space, which together consist of
approximately 1,400 square meters, in Lyon, France. The lease for this facility expires in June 2024. In July 2019, we entered into another lease in Lyon,
France for additional offices and laboratory space, which together will consist of approximately 3,000 square meters. The lease for this facility expires in
June 2029, and we will have the ability to terminate the lease either in June 2025 or June 2028. We believe our current leased space is sufficient to meet our
current needs in Europe.

In February 2016, we opened our U.S. office in Cambridge, Massachusetts. In 2018, we entered into a lease for 3,000 square meters of manufacturing and
office space in Princeton, New Jersey, under a lease that expires in June 2029. The Princeton Facility became

72

operational in the fourth quarter of 2019 and had been used to produce GMP-compliant batches since then. Following the opening of the Princeton Facility,
we terminated our agreement with the American Red Cross for the use of a manufacturing facility in Philadelphia, Pennsylvania in January 2020. In April
2022,  we  entered  into  the  Catalent  Purchase  Agreement,  pursuant  to  which  we  sold  to  Catalent,  among  other  things,  certain  assets  and  inventory  of
materials located at the Princeton Facility for Catalent’s use in the manufacture of our lead product candidate, eryaspase. In connection therewith, we also
entered  into  an  interim  supply  agreement  with  Catalent  under  which  Catalent  agreed  to  manufacture  and  supply  eryaspase  to  us  for  our  clinical  and
commercial uses of eryaspase in the United States.

We  believe  our  production  facility  in  Lyon,  France  and  our  commercial  supply  agreement  with  Catalent  will  be  sufficient  to  supply  eryaspase  for  our
ongoing clinical trials and to meet our commercial needs for eryaspase in Europe and United States, if approved.

Item 5. Operating and Financial Review and Prospects.

You  should  read  the  following  discussion  of  our  operating  and  financial  review  and  prospects  in  conjunction  with  our  audited  consolidated  financial
statements  and  the  related  notes  thereto  included  elsewhere  in  this  Annual  Report.  In  addition  to  historical  information,  the  following  discussion  and
analysis contains forward-looking statements that reflect our plans, estimates and beliefs. Our actual results and the timing of events could differ materially
from those anticipated in the forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and
elsewhere in this Annual Report, particularly in sections titled “Risk Factors” and “Special Note Regarding Forward-Looking Statements.”

Overview

®

We  are  a  clinical-stage  biopharmaceutical  company  developing  innovative  therapies  for  severe  forms  of  cancer  and  orphan  diseases.  Leveraging  our
proprietary ERYCAPS   platform,  which  uses  a  novel  technology  to  encapsulate  therapeutic  drug  substances  inside  erythrocytes,  or  red  blood  cells,  or
RBC. We are developing a pipeline of product candidates for patients with high unmet medical needs. Our lead product candidate eryaspase, which we also
refer to as GRASPA , targets the metabolism of cancer cells by depriving the cells of asparagine, an amino acid necessary for their survival and critical in
maintaining  the  cells’  rapid  growth  rate.  We  are  currently  developing  eryaspase  for  the  treatment  of  severe  tumors,  including  pancreatic  cancer,  acute
lymphoblastic leukemia, or ALL, and triple negative breast cancer, or TNBC. We are also exploring the use of our ERYCAPS  platform for developing
cancer immunotherapies and enzyme therapies.

®

®

Since  our  inception,  we  have  devoted  substantially  all  of  our  financial  resources  to  research  and  development  efforts,  including  conducting  preclinical
studies and clinical trials of our product candidates, providing general and administrative support for our operations and protecting our intellectual property.

As of December 31, 2021, we had cash and cash equivalents amounted of €33.7 million ($38.1 million). Historically, we have financed our operations and
growth through private and public offerings of our equity securities, convertible notes, loans, public assistance programs in support of innovation, such as
the conditional advances and subsidies from Bpifrance, a French public investment bank and from research tax credits. In May 2013, we completed the
initial public offering of our ordinary shares on Euronext Paris, from which we raised €17.7 million in gross proceeds. In November 2017, we completed a
global offering for gross proceeds of $143.7 million, or €123.6 million. The global offering consisted of a U.S. initial public offering of 5,389,021 ADS,
each representing one ordinary share, and a concurrent private placement in Europe and other countries outside of the United States and Canada of 791,116
ordinary shares. Our net proceeds from the global offering were approximately €112.1 million ($130.4 million).

Since our inception in 2004, we have incurred significant operating losses. Our net loss was €62.7 million, €73.3 million and €53.8 million for the years
ended December 31, 2019, 2020 and 2021, respectively. We had a consolidated shareholders' equity of €22.8 million as of December 31, 2021, and we
expect to incur significant expenses and substantial operating losses over the next several years as we continue our research and development efforts and
advance our clinical development programs in Europe and the United States.

The COVID-19 pandemic has caused delays in the recruitment of patients for the TRYbeCA1 study in 2020 and thus in the interim analysis which took
place in February 2021. On October 25, 2021, ERYTECH communicated the first results of the TRYbeCA-1 study. These results show that the Phase 3
TRYbeCA-1 trial did not meet the primary efficacy endpoint of overall survival (OS). Nevertheless, a preliminary analysis of the results of a subgroup of
patients indicated a potential efficacy signal for patients treated with eryaspase in combination with FOLFIRI chemotherapy cocktail.

73

Although it is difficult to predict future liquidity requirements, we believe that our existing cash and cash equivalents as of the date of this Annual Report
will be sufficient to fund our operations until mid-2024. Refer to "Item 3.D.1 Risks Related to our Financial Position and Capital Needs for further details.

Our net losses may fluctuate significantly from quarter to quarter and year to year, depending on the timing of our clinical trials, the receipt of milestone
payments,  if  any,  and  our  expenditures  on  other  research  and  development  activities.  We  anticipate  that  our  expenses  will  increase  substantially  in
connection with our ongoing activities, as we:

•

•

•

•

conduct our ongoing and planned clinical trials of eryaspase in Europe and in the United States;

seek regulatory approvals for any product candidates that successfully complete clinical trials;

scale-up our manufacturing capabilities to support the launch of additional clinical studies and the commercialization of our product candidates,
if approved;

establish a sales and marketing infrastructure for the commercialization of our product candidates, if approved;

• maintain, expand and protect our intellectual property portfolio;

•

•

•

•

continue the research and development of our other product candidates, including planned and future clinical trials;

seek to discover and develop additional product candidates;

seek to attract and retain new and existing skilled personnel; and

create additional infrastructure to support our operations as a public company listed in the United States.

Until such time that we can generate substantial revenue from product sales, we expect to finance these expenses and our operating activities through a
combination  of  equity  offerings,  debt  financings,  government  or  other  third-party  funding,  marketing  and  distribution  arrangements  and  other
collaborations,  strategic  alliances  and  licensing  arrangements.  However,  we  may  be  unable  to  raise  additional  funds  or  enter  into  other  funding
arrangements when needed on favorable terms, or at all, which would have a negative impact on our financial condition and could force us to delay, limit,
reduce or terminate our development programs or commercialization efforts or grant rights to third parties to develop or market product candidates that we
would otherwise prefer to develop and market ourselves. Moreover, no assurance can be given at this time as to whether we will be able to achieve these
financing objectives. Our ability to successfully transition to profitability will be dependent upon achieving a level of revenues adequate to support our cost
structure. We cannot assure you that we will ever be profitable or generate positive cash flow from operating activities.

The consolidated financial statements as of and for the years ended December 31, 2019, 2020 and 2021 included in this Annual Report have been prepared
in accordance with IFRS as issued by the IASB with no difference with the statutory consolidated financial statements and were approved and authorized
for issuance by our board of directors on April 26, 2022. Due to the listing of our ordinary shares on Euronext Paris and in accordance with the European
Union’s regulation No. 1606/2002 of July 19, 2002 as amended, our consolidated financial statements have also been prepared in accordance with IFRS as
adopted by the European Union, or EU.

Financial Operations Overview

Operating Income

To date, we have not generated any revenue from the sale of products. Our ability to generate product revenue and to become profitable will depend upon
our  ability  to  successfully  develop  and  commercialize  eryaspase  and  our  other  product  candidates.  Because  of  the  numerous  risks  and  uncertainties
associated with product development and regulatory approval, we are unable to predict the amount or timing of product revenue. Our operating income
consists of other income.

Research Tax Credit

The research tax credit (crédit d’impôt recherche), or CIR, is granted to companies by the French tax authorities in order to encourage them to conduct
technical and scientific research. Companies demonstrating that they have expenses that meet the required criteria, including research expenses located in
France or, since January 1, 2005, within the European Union or in another state that is a party to the agreement in the European Economic Area that has
concluded  a  tax  treaty  with  France  that  contains  an  administrative  assistance  clause,  receive  a  tax  credit  which  can  be  used  against  the  payment  of  the
corporate tax due the fiscal year in which the expenses were incurred and during the next three fiscal years, or, as applicable, can be reimbursed for the
excess portion. The expenses taken into account for the calculation of the CIR only involve research and development expenses.

The main characteristics of the CIR are the following:

74

•

•

•

the CIR results in a cash inflow from the tax authorities paid directly to us as we are not subject to corporate income tax;

a company’s corporate income tax liability does not limit the amount of the CIR;

the CIR is not included in the determination of the corporate income tax.

As  a  result,  we  have  concluded  that  the  CIR  meets  the  definition  of  a  government  grant  as  defined  in  IAS  20  Accounting  for  Government  Grants  and
Disclosure  of  Government  Assistance. As  no  research  and  development  expenditure  is  capitalized  before  obtaining  a  marketing  authorization,  the  CIR
related to a research program is entirely recognized in "other income" in our statement of income (loss).

Subsidies

We have received financial assistance from Bpifrance and other governmental organizations in connection with the development of our product candidates.
Bpifrance’s mission is to provide assistance and support to emerging French enterprises to facilitate the development and commercialization of innovative
technologies.

Funds are recognized in "other income" in our statement of income (loss) for the fiscal year in which the financed expenses were recorded.

Revenue from Licenses or Other Contracts

Since January 1, 2018, agreements are analyzed and recorded in accordance with IFRS 15 Revenue from contracts with customers, or IFRS 15.

Partnership with Orphan Europe for NOPHO clinical trial

Pursuant to the terms of our distribution agreement, Orphan Europe agreed to finance the NOPHO trial for a total amount of €600 thousand. We recognized
revenues related to this partnership under “other income” in our statement of income (loss).

License agreement with SQZ Biotechnologies

Pursuant to the terms of our license agreement with SQZ Biotechnologies, we granted to SQZ Biotechnologies an exclusive worldwide license to develop
antigen  specific  immune  modulating  therapies  employing  red  blood  cell-based  approaches.  In  accordance  with  IFRS  15,  this  agreement  grants  to  SQZ
Biotechnologies a right to use the underlying intellectual property. Consequently, the income is recognized when SQZ Biotechnologies can begin to use the
licensed intellectual property.

Operating Expenses

Our operating expenses consist primarily of research and development expenses and general and administrative expenses.

Research and development expenses

We engage in substantial research and development efforts to develop innovative pharmaceutical product candidates.

Research and development expenses consist primarily of:

•

•

•

•

services, subcontracting and consulting fees, that primarily include the cost of third-party contractors such as contract research organizations, or
CROs, who conduct our clinical trials;

personnel  costs,  including  salaries,  related  benefits  and  share-based  compensation,  for  our  employees  engaged  in  scientific  research  and
development functions;

purchases of raw materials, especially asparaginase, and transportation costs associated;

depreciation and amortization expenses.

Since  our  inception,  our  research  and  development  efforts  have  been  related  primarily  to  our  completed  and  ongoing  clinical  trials  of  eryaspase  for  the
treatment of pancreatic cancer, ALL and AML. In June 2018, we ceased the development program for eryaspase in ALL and are focusing our development
efforts on eryaspase for the treatment of selected solid tumors. The resources that became available as a result of this strategic decision were allocated to
what  we  estimate  is  a  significantly  larger  unmet  medical  need  and  market  opportunity  for  the  potential  treatment  of  solid  tumors,  including  pancreatic
cancer and TNBC. This decision did not have a significant impact on our consolidated financial statements.

75

Our direct research and development expenses consist principally of external costs, such as fees paid to consultants, laboratories and CROs in connection
with our clinical trials, and purchases of raw materials which we allocate to our specific research programs.

Research and development activities are central to our business model. Product candidates in later stages of clinical development generally have higher
development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We
expect  that  our  research  and  development  expenses  will  continue  to  increase  in  the  foreseeable  future  as  we  initiate  clinical  trials  for  certain  product
candidates and pursue later stages of clinical development of other product candidates, and will seek regulatory approvals for our product candidates, if
clinical trial are successfully completed.

We cannot determine with certainty the duration or costs of the current or future clinical trials of our product candidates or if, when, or to what extent we
will  generate  revenue  from  the  commercialization  and  sale  of  any  of  our  product  candidates  that  obtain  regulatory  approval.  We  may  never  succeed  in
achieving regulatory approval for any of our product candidates. The duration, costs and timing of clinical trials and development of our product candidates
will depend on a variety of factors, including:

•

•

•

•

•

the  scope,  rate  of  progress  and  expense  of  our  ongoing,  as  well  as  any  additional,  non-clinical  studies,  clinical  trials  and  other  research  and
development activities;

clinical trial and early-stage results;

the terms and timing of regulatory approvals;

the expense of filing, prosecuting, defending and enforcing patent claims and other intellectual property rights; and

the ability to market, commercialize and achieve market acceptance for eryaspase or any other product candidate that we may develop in the
future.

A change in the outcome of any of these variables with respect to the development of product candidates that we are developing could mean a significant
change  in  the  costs  and  timing  associated  with  the  development  of  such  product  candidates.  For  example,  if  the  FDA,  the  EMA  or  other  regulatory
authority were to require us to conduct non-clinical and clinical studies beyond those which we currently anticipate will be required for the completion of
clinical  development,  or  if  we  experience  significant  delays  in  enrollment  in  any  clinical  trials,  we  could  be  required  to  spend  significant  additional
financial resources and time on the completion of clinical development.

General and Administrative

General and administrative expenses consists primarily of :

•

•

services, subcontracting and consulting fees, mainly related to legal services, accounting and audit, IT, insurance costs and overhead costs;

personnel  costs  including  share-based  compensation  for  personnel  other  than  employees  engaged  in  scientific  research  and  development
functions;

We anticipate that our general and administrative expenses will increase in the future as we grow our support functions for the expected increase in our
research and development activities and the potential commercialization of our product candidates.

Financial Income (Loss)

Financial income (loss) relates primarily to:

•

•

•

•

expenses  and  income  on  convertibles  notes  recognized  in  accordance  with  IFRS  9  (amortized  cost  and  change  in  fair  value  of  embedded
derivatives),

interest expenses incurred on financial liabilities and lease liabilities,

income received from cash and cash equivalents and

gains and losses on exchange rate variations on financial and investing operation.

Income tax

We do not recognize current tax expense. Deferred tax assets resulting from temporary differences or tax losses carried forward are limited to the deferred
tax liabilities with the same maturity, except where their allocation on future taxable income is probable.

receive the CIR recognized for the 2021 year in 2022.

Revenues from licenses or other contracts in 2019 are primarily associated with our license agreement with SQZ Biotechnologies.

Research and Development Expenses

Our research and development expenses amounted to €52,193 thousand in 2019, €57,580 thousand in 2020 (an increase of 10% compared to 2019) and
€45,100 thousand in 2021 (a decrease of 22% compared to 2020).

We have always focused our research and development expenses on the development of eryaspase for the treatment of pancreatic cancer, ALL and AML.
In June 2018, the Company decided to focus its development efforts on eryaspase for the treatment of certain solid tumors (including pancreatic cancer).
Final results from the TRYbeCA-1 trial were announced by the Company in October 2021. The trial did not meet its primary endpoint of overall survival.
ERYTECH  will  now  focus  its  efforts  on  its  late-stage  program  with  eryaspase  in  patients  with  hypersensitive  acute  lymphoblastic  leukemia  (ALL)  and
confirms its intention to file a Biologics License Application (BLA) in the United States.

Our research and development expenses are broken down in the table below.

77

The change in research and development expenses for periods presented is mainly due to:

• An  increase  in  costs  related  to  eryaspase  of  €5,729  thousand  in  2020  mostly  to  support  our  TRYbeCA-1  patient  treatment.  A  decrease  of
€10,983 thousand in 2021 because of the completion of our TRYbeCA-1 trial. As a result patient cost decreased by €6,601 thousand in 2021 and
CRO cost decreased €4,452 thousand compared to 2020.

• A decrease in costs related to erymethionase of €1,986 thousand in 2020 and €11 thousand in 2021 due to our decision to focus our financial

resources on other strategic priorities.

•

• An  increase  in  personnel  expenses  of  €662  thousand  in  2020,  mainly  related  to  an  increase  in  headcount  of  our  research  and  development
workforce, especially in technical operations, in connection with our ongoing clinical trials and particularly, the launch of the TRYbeCA-1 trial
in September 2018. A small decrease in personnel expenses of €35 thousand in 2021. The average number of full-time employees allocated to
our research and development workforce was 156 in 2019, 166 in 2020 and 152 in 2021.

• An increase in depreciation and amortization expenses of €724 thousand in 2020 and €651 thousand in 2021, mainly related to:

◦

the recognition of an impairment expense of €1,036 thousand in 2019 and €560 thousand in 2021 on a production process recognized in
intangible asset

General and Administrative Expenses

Our general and administrative expenses amounted to €17,164 thousand in 2019, €14,970 thousand in 2020 (a decrease of (13)% compared to 2019) and
€15,595 thousand in 2021 (an increase by 4% compared to 2020).

The increase in 2021 in G&A cost is related mostly to the increase of D&O insurance premium by €1,344 thousand.

Our general and administrative expenses are mainly composed of:

•

•

Services, subcontracting and consulting fees amounting to €7,964 thousand in 2019, €5,962 thousand in 2020 and €6,684 thousand in 2021. The
significance  of  these  expenses  in  2019  compared  to  2020  was  mainly  due  to  the  establishment  of  our  Princeton,  New  Jersey  manufacturing
facility; and

Personnel expenses amounting to €6,331 thousand in 2019, €6,573 thousand in 2020 and €6,174 thousand in 2021. The average number of full-

In September 2020, we entered into a sales agreement with Cowen with respect to an ATM offering program pursuant to which we may issue and sell, from
time to time at our sole discretion, ordinary shares in the form of ADSs to eligible investors at market prices, with aggregate gross sales proceeds of up to
$30 million, subject to the regulatory limit of 20% dilution (this threshold is calculated based on the total number of shares listed on Euronext during the
twelve months before the issuance).

In February 2021, we sold shares under this ATM offering program resulting in gross proceeds of $8.0 million, or €6.6 million, resulting in net proceeds of
$7.8 million or €6.4 million. As of the date of this Annual Report, $22.0 million remained available for future issuance until September 2023, subject to the
regulatory limit of 20% dilution.

The  TEDAC  research  program,  which  is  funded  by  non-refundable  subsidies  and  conditional  advances  from  Bpifrance,  will  be  funded  according  to  a
specified schedule set forth in the contract, subject to completion of milestones. As the program advances, we will

80

provide  Bpifrance  with  interim  progress  reports  and  a  final  report  when  the  funded  project  ends.  Based  on  these  reports,  we  are  entitled  to  conditional
advances and non-refundable subsidies, each award being made to help fund a specific development milestone.

2020  and  2021.  Reduction  in  working  capital  requirements  in  2019  and  2020  is  related  to  the  launch  of  the  phase  3  clinical  trial  in  pancreatic  cancer
TRYbeCA1 and more specifically to the increase in hospital costs (associated accruals), for which

81

there is a significant time difference between the provision of the services and the actual invoicing from the hospitals. In 2021, the negative impact on
working capital is mainly related to the decrease of accruals for hospital costs as invoices are received and paid.

Executive Compensation Arrangements

For  a  discussion  of  our  employment  arrangements  with  our  executive  officers,  see  “Item  7.B.—Related  Party  Transactions—Arrangements  with  Our
Directors  and  Executive  Officers.”  Except  the  arrangements  described  in  “Item  7.B.—Related  Party  Transactions—Agreements  with  Our  Directors  and
Executive Officers,” there are no arrangements or understanding between us and any of our other executive officers providing for benefits upon termination
of their employment, other than as required by applicable law.

Limitations on Liability and Indemnification Matters

Under French law, provisions of bylaws that limit the liability of directors are prohibited. However, French law allows sociétés anonymes to contract for
and maintain liability insurance against civil liabilities incurred by any of their directors and officers involved in a third-party action, provided that they
acted in good faith and within their capacities as directors or officers of the company. Criminal liability cannot be indemnified under French law, whether
directly by the company or through liability insurance.

We have obtained directors’ and officers’ liability insurance for our directors and officers, which includes coverage against liability under the Securities
Act. We have entered into agreements with our directors and executive officers to provide contractual indemnification. With certain exceptions and subject
to limitations on indemnification under French law, these agreements provide for indemnification for damages and expenses including, among other things,
attorneys’ fees, judgments and settlement amounts incurred by any of these individuals in any action or proceeding arising out of his or her actions in that
capacity.

These agreements may discourage shareholders from bringing a lawsuit against our directors and executive officers for breach of their fiduciary duty. These
provisions also may have the effect of reducing the likelihood of derivative litigation against directors and executive officers, even though such an action, if
successful, might otherwise benefit us and our shareholders. Furthermore, a shareholder’s investment in our equity securities may be adversely affected to
the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these insurance agreements.

89

Equity Incentives

We  believe  our  ability  to  grant  equity  incentives  is  a  valuable  and  necessary  compensation  tool  that  allows  us  to  attract  and  retain  the  best  available
personnel for positions of substantial responsibility, provides additional incentives to employees and promotes the success of our business. Due to French
corporate  law  and  tax  considerations,  we  have  historically  granted  several  different  equity  incentive  instruments  to  our  directors,  executive  officers,
employees and other service providers, including:

•

•

•

•

founder’s  share  warrants  (otherwise  known  as  bons  de  souscription  de  parts  de  créateurs  d’entreprise,  or  BSPCE),  which  are  granted  to  our
officers and employees;

share  warrants  (otherwise  known  as  bons  de  souscription  d’actions,  or  BSA),  which  have  historically  only  been  granted  to  non-employee
directors;

restricted, or free, shares (otherwise known as actions gratuites); and

stock options (otherwise known as options de souscription et/ou d’achat d’actions).

Our board of directors’ authority to grant these equity incentive instruments and the aggregate amount authorized to be granted under these instruments
must  be  approved  by  a  two-thirds  majority  of  the  votes  held  by  our  shareholders  present,  represented  or  voting  by  authorized  means,  at  the  relevant
extraordinary shareholders’ meeting. Once approved by our shareholders, our board of directors can grant share warrants (BSA) for up to 18 months, and
restricted (free) shares and stock options for up to 38 months from the date of the applicable shareholders’ approval. The authority of our board of directors
to  grant  equity  incentives  may  be  extended  or  increased  only  by  extraordinary  shareholders’  meetings.  As  a  result,  we  typically  request  that  our
shareholders authorize new pools of equity incentive instruments at every annual shareholders’ meeting.

We have seven share-based compensation plans for our executive officers, non-employee directors and employees: the 2014 Plan, the 2016 Plan, the 2017
Plan,  the  2018  Plan,  the  2019  Plan,  the  2020  Plan  and  the  2021  Plan  or  the  Plans.  In  general,  founder’s  share  warrants  and  share  warrants  no  longer
continue to vest following termination of the employment, office or service of the holder and all vested shares must be exercised within post-termination
exercise periods set forth in the grant documents. In the event of certain changes in our share capital structure, such as a consolidation or share split or
dividend, French law and applicable grant documentation provides for appropriate adjustments of the numbers of shares issuable and/or the exercise price
of the outstanding warrants.

As of December 31, 2021, employee warrants, non-employee warrants, employee stock options and free shares were outstanding allowing for the purchase
of an aggregate of 3,071,392 ordinary shares at a weighted average exercise price of €11.65 ($13.20) per ordinary share based on the exchange rate in effect
as of such date (this weighted average exercise price does not include 969,081 ordinary shares issuable upon the vesting of outstanding free shares that may
be issued for free with no exercise price being paid).

Founder’s Share Warrants (BSPCE)

Founder’s share warrants have traditionally been granted to certain of our employees who were French tax residents because the warrants carry favorable
tax  and  social  security  treatment  for  French  tax  residents.  Similar  to  options,  founder’s  share  warrants  entitle  a  holder  to  exercise  the  warrant  for  the
underlying vested shares at an exercise price per share determined by our board of directors and at least equal to the fair market value of an ordinary share
on the date of grant. However, unlike options, the exercise price per share is fixed as of the date of implementation of the plans pursuant to which the
warrants may be granted, rather than as of the date of grant of the individual warrants.

shareholder authorization, under applicable law, we are no longer eligible to issue any further founders’ share warrants (BSPCE).

Share Warrants (BSA)

Share warrants have historically only been granted to our non-employee directors. Similar to options, share warrants entitle a holder to exercise the warrant
for the underlying vested shares at an exercise price per share determined by our board of directors and at least equal to the fair market value of an ordinary
share on the date of grant. However, unlike options, the exercise price per share is fixed as of the date of implementation of the plans pursuant to which the
warrants may be granted, rather than as of the date of grant of the individual warrants.

Our  shareholders,  or  pursuant  to  delegations  granted  by  our  shareholders,  our  board  of  directors,  determines  the  recipients  of  the  warrants,  the  dates  of
grant, the number and exercise price of the share warrants to be granted, the number of shares issuable upon exercise and certain other terms and conditions
of the share warrants, including the period of their exercisability and their vesting schedule.

Free Shares (AGA)

Under our Free Share Plans, we have granted free shares to certain of our employees and officers.

Free shares may be granted to any individual employed by us or by any affiliated company. Free shares may also be granted to our Chairman, to our Chief
Executive  Officer  and  to  our  Deputy  General  Managers.  However,  no  free  share  may  be  granted  to  a  beneficiary  holding  more  than  10%  of  our  share
capital  or  to  a  beneficiary  who  would  hold  more  than  10%  of  our  share  capital  as  a  result  of  such  grant.  The  maximum  number  of  shares  that  may  be
granted or issued is 250,000 under the 2016 Free Share Plan, 300,000 under the 2017 Free Share Plan, 150,000 under the 2018 Free Share Plan, 400,000
under the 2019 Free Share Plan, the 2020 Free Share Plan and the 2021 Free Share Plan. In addition, under French law, the maximum number of shares that
may be granted shall not exceed 10% of the share capital as at the date of grant of the free shares (30% if the allocation benefits all employees).

Our board of directors has the authority to administer 2016 Free Share Plan, 2017 Free Share Plan, 2018 Free Share Plan, 2019 Free Share Plan, 2020 Free
Share Plan and 2021 Free Share Plan, or the Free Share Plans. Subject to the terms of the Free Share Plans, our board of directors determines the recipients,
the  dates  of  grant,  the  number  of  free  shares  to  be  granted  and  the  terms  and  conditions  of  the  free  shares,  including  the  length  of  their  vesting  period
(starting on the grant date, during which the beneficiary holds a right to acquire shares for free but has not yet acquired any shares) and holding period
(starting when the shares are issued and definitively acquired but may not be transferred by the recipient) within the limits determined by the shareholders.
Our shareholders have determined that the vesting period should be set by the board of directors and should not be less than one year from the date of grant
and that the optimal holding period should be set by the board of directors. From the beginning of the vesting period, the cumulated vesting and holding
period should not be less than two years.

The  board  of  directors  has  the  authority  to  modify  awards  outstanding  under  our  Free  Share  Plans,  subject  to  the  consent  of  the  beneficiary  for  any
modification adverse to such beneficiary. For example, the board has the authority to release a beneficiary from the continued service condition during the
vesting period after the termination of the employment.

The free shares granted under our Free Share Plans will be definitively acquired at the end of the vesting period as set by our board of directors subject to
continued service during the vesting period, except if the board releases a given beneficiary from this condition upon termination of his or her employment
contract, or pursuant to the achievement of the performance conditions set out in the Free Share Plans.

The vesting of the free shares granted under the 2016 Free Share Plan, 2017 Free Share Plan and 2018 Free Share Plan is divided in three equal shares
(33.33%), respectively following the first, second and third year following the date of grant. The vesting of the free shares granted under the 2019 Free
Share Plan, the 2020 Free Share Plan and the 2021 Free Share Plan is in five tranches: the first (32%) one year following the date of grant, the second
(32%) two years following the date of grant, the third (32%) three years following the date of grant, the fourth (2%) four years following the date of grant
and the fifth (2%) five years following the date of grant.

At the end of the vesting period, the beneficiary will be the owner of the shares. However, the shares may not be sold, transferred or pledged during the
holding period. In the event of disability before the end of the vesting period, the free shares shall be definitively acquired by the beneficiary on the date of
disability. In the event the beneficiary dies during the vesting period, the free shares shall be definitively acquired at the date of the request of allocation
made by his or her beneficiaries in the framework of the inheritance provided that such request is made within six months from the date of death.

Stock Options (SO)

Stock options issued pursuant to our Stock Option Plans provide the holder with the right to purchase a specified number of ordinary shares from us at a
fixed exercise price payable at the time the stock option is exercised, as determined by our board of directors. Our Stock Option Plans generally provide
that the exercise price for any stock option will be no less than 95% of the average of the closing sales prices per ordinary share during the 20 market
trading days prior to the day of the board of directors’ decision to grant the options. The maximum number of ordinary shares subject to stock options
issued is 250,000 ordinary shares under the 2016 Stock Option Plan, 300,000 under the 2017 Stock Option Plan, 300,000 under the 2018 Stock Option
Plan, 700,000 under the 2019 Stock Option Plan, 500,000 under the 2020 Stock Option Plan and 700,000 under the

94

2021 Stock Option Plan. Incentive stock options and non-statutory stock options may be granted under our Stock Option Plan.

Stock options may be granted to any individual employed by us or by any affiliated company. Stock options may also be granted to our Chairman, our
General Manager and to our Deputy General Managers. In addition, incentive stock options may not be granted to owners of shares possessing 10% or
more of the share capital of the company.

Our board of directors has the authority to administer and interpret the 2016 Stock Option Plan, 2017 Stock Option Plan, 2018 Stock Option Plan, 2019
Stock Option Plan, 2020 Stock Option Plan and the 2021 Stock Option Plan, or the Stock Option Plans. Subject to the terms and conditions of our Stock
Option  Plans,  our  board  of  directors  determines  the  recipients,  dates  of  grant,  exercise  price,  number  of  stock  options  to  be  granted  and  the  terms  and
conditions of the stock options, including the length of their vesting schedules. Our board of directors is not required to grant stock options with vesting and
exercise terms that are the same for every participant. The term of each stock option granted under our Stock Option Plan will generally be 10 years from
the date of grant. Further, stock options will generally terminate on the earlier of when the beneficiary ceases to be an employee of our company or upon
certain transactions involving our company.

The board of directors has the authority to modify awards outstanding under our Stock Option Plans, subject to the written consent of the beneficiary for
any modification adverse to such beneficiary. For example, the board of directors has the authority to extend a post-termination exercise period.

Stock options granted under our Stock Option Plans generally may not be sold, transferred or pledged in any manner other than by will or by the laws of
descent or distribution. In the event of disability, unless otherwise resolved by our board of directors, the beneficiary’s right to exercise the vested portion
of his or her stock option generally terminates six months after the last day of such beneficiary’s service, but in any event no later than the expiration of the
maximum term of the applicable stock options. In the event the beneficiary dies during the vesting period, then, unless otherwise resolved by our board of
directors,  the  beneficiary’s  estate  or  any  recipient  by  inheritance  or  bequest  may  exercise  any  portion  of  the  stock  option  vested  at  the  time  of  the
beneficiary’s death within the six months following the date of death, but in any event no later than the expiration of the maximum term of the applicable
stock options.

6.C.Board Practices.

Prior  to  May  2013,  our  company  had  a  two-tier  corporate  governance  system:  an  executive  board  was  responsible  for  managing  the  company  and  a
supervisory board oversaw and advised the executive board. We have now established a board of directors. Our board of directors currently consists of
eight members, less than a majority of whom are citizens or residents of the United States. As permitted by French law, one of our directors, Hilde Windels
BV, is a legal entity. This entity has designated an individual, Hilde Windels, to represent it and to act on its behalf at meetings of our board of directors.
This  representative  has  the  same  responsibilities  to  us  and  to  our  shareholders  as  he  or  she  would  have  if  he  or  she  had  been  elected  to  our  board  of
directors in his or her individual capacity.

Under  French  law  and  our  bylaws,  our  board  of  directors  must  be  comprised  of  between  three  and  18  members,  without  prejudice  to  the  derogation
established by law in the event of merger. Since January 1, 2017, the number of directors of each gender may not be less than 40%. As of the date of this
Annual Report on Form 20-F, our board is composed of five men and three women. Any appointment made in violation of this limit that is not remedied
within six months of this appointment will be null and void. Within these limits, the number of directors is determined by our shareholders. Directors are
appointed,  reappointed  to  their  position,  or  removed  by  the  company’s  ordinary  general  meeting,  and  in  particular,  any  appointment  which  remedies  a
violation of the 40% limit must be ratified by our shareholders at the next ordinary general meeting. Their term of office, in accordance with our bylaws, is
three years. Directors chosen or appointed to fill a vacancy must be elected by our board of directors for the remaining duration of the current term of the
vacant director. The appointment must then be ratified at the next shareholders’ general meeting. In the event the board of directors would be comprised of
less than three directors as a result of a vacancy, the remaining directors shall immediately convene a shareholders’ general meeting to elect one or several
new directors so there are at least three directors serving on the board of directors, in accordance with French law.

The following table sets forth the names of our directors, the years of their initial appointment as directors of the board and the expiration dates of their
current term.

At the end of the ordinary general meeting convened to approve the accounts for the previous financial year during the year in which their term office
expires.
Sven  Andréasson  has  been  appointed  as  director  in  his  individual  capacity  following  the  resignation  of  Galenos  SPRL  of  which  he  was  the  legal
representative.
Hilde Windels BV was appointed as a director by our shareholders at our combined general meeting in June 2017. Hilde Windels BV has designated
an individual, Hilde Windels, to represent it and to act on its behalf at meetings of our board of directors. She served as a member of the board of
directors in her individual capacity from 2014 to 2017. Hilde Windels BV is a company controlled by Ms. Windels.

Director Independence

As a foreign private issuer, under the listing requirements and rules of the Nasdaq Global Select Market, we are not required to have independent directors
on our board of directors, except to the extent that our audit committee is required to consist of independent directors. Nevertheless, our board of directors
has  undertaken  a  review  of  the  independence  of  the  directors  and  considered  whether  any  director  has  a  material  relationship  with  us  that  could
compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. Based upon information requested from, and
provided  by,  each  director  concerning  such  director’s  background,  employment  and  affiliations,  including  family  relationships,  our  board  of  directors
determined that all of our directors, except for Mr. Beyen, qualify as “independent directors” as defined under applicable rules of the Nasdaq Global Select
Market and the independence requirements contemplated by Rule 10A-3 under the Exchange Act. In making these determinations, our board of

97

 
directors considered the current and prior relationships that each non-employee director has with our company and all other facts and circumstances that
our  board  of  directors  deemed  relevant  in  determining  their  independence,  including  the  beneficial  ownership  of  our  securities  by  each  non-employee
director and his or her affiliated entities (if any).

Role of the Board in Risk Oversight

Our  board  of  directors  is  primarily  responsible  for  the  oversight  of  our  risk  management  activities  and  has  delegated  to  the  audit  committee  the
responsibility to assist our board in this task. The audit committee also monitors our system of disclosure controls and procedures and internal control over
financial  reporting  and  reviews  contingent  financial  liabilities.  The  audit  committee,  among  other  things,  examines  our  balance  sheet  commitments  and
risks and the relevance of risk monitoring procedures. While our board oversees our risk management, our management is responsible for day-to-day risk
management  processes.  Our  board  of  directors  expects  our  management  to  consider  risk  and  risk  management  in  each  business  decision,  to  proactively
develop and monitor risk management strategies and processes for day-to-day activities and to effectively implement risk management strategies adopted
by the board of directors. We believe this division of responsibilities is the most effective approach for addressing the risks we face.

Corporate Governance Practices

As a French société anonyme, we are subject to various corporate governance requirements under French law. In addition, as a foreign private issuer listed
on  the  Nasdaq  Global  Select  Market,  we  are  subject  to  Nasdaq  corporate  governance  listing  standards.  However,  the  corporate  governance  standards
provide that foreign private issuers are permitted to follow home country corporate governance practices in lieu of Nasdaq rules, with certain exceptions.
We  currently  rely  on  these  exemptions  for  foreign  private  issuers  and  follow  French  corporate  governance  practices  in  lieu  of  the  Nasdaq  corporate
governance  rules,  which  would  otherwise  require  that  (1)  a  majority  of  our  board  of  directors  consist  of  independent  directors;  (2)  we  establish  a
nominating and corporate governance committee; and (3) our remuneration committee be composed entirely of independent directors.

As a foreign private issuer, we are required to comply with Rule 10A-3 of the Exchange Act, relating to audit committee composition and responsibilities.
Rule  10A-3  provides  that  the  audit  committee  must  have  direct  responsibility  for  the  nomination,  compensation  and  choice  of  our  auditors,  as  well  as
control  over  the  performance  of  their  duties,  management  of  complaints  made,  and  selection  of  consultants.  However,  if  the  laws  of  a  foreign  private
issuer’s  home  country  require  that  any  such  matter  be  approved  by  the  board  of  directors  or  the  shareholders,  the  audit  committee’s  responsibilities  or
powers with respect to such matter may instead be advisory. Under French law, the audit committee may only have an advisory role and appointment of our
statutory auditors, in particular, must be decided by the shareholders at our annual meeting.

In addition, Nasdaq rules require that a listed company specify that the quorum for any meeting of the holders of common stock be at least 33 1/3% of the
outstanding  shares  of  the  company’s  voting  stock.  Consistent  with  French  law,  our  bylaws  provide  that  a  quorum  requires  the  presence  of  shareholders
having at least (1) 20% of the shares entitled to vote in the case of an ordinary shareholders’ general meeting or at an extraordinary shareholders’ general
meeting where shareholders are voting on a capital increase by capitalization of reserves, profits or share premium, or (2) 25% of the shares entitled to vote
in the case of any other extraordinary shareholders’ general meeting. If a quorum is not present, the meeting is adjourned. There is no quorum requirement
when  an  ordinary  general  meeting  is  reconvened,  but  the  reconvened  meeting  may  consider  only  questions  which  were  on  the  agenda  of  the  adjourned
meeting. When an extraordinary general meeting is reconvened, the quorum required is 20% of the shares entitled to vote, except where the reconvened
meeting  is  considering  capital  increases  through  capitalization  of  reserves,  profits  or  share  premium.  For  these  matters,  no  quorum  is  required  at  the
reconvened meeting. If a quorum is not present at a reconvened meeting requiring a quorum, then the meeting may be adjourned for a maximum of two
months.

Furthermore, we follow French corporate governance practices in lieu of the Nasdaq corporate governance rules that require shareholder approval prior to
specified  issuances  of  securities.  More  specifically,  Nasdaq  Marketplace  Rule  5635  requires  a  U.S.  domestic  listed  company  to  obtain  shareholder
approval:  (1)  prior  to  the  issuance  of  securities  when  the  issuance  or  potential  issuance  will  result  in  a  change  of  control  of  the  issuer;  (2)  prior  to  the
issuance of securities in connection with a transaction other than a public offering involving the sale, issuance or potential issuance by the issuer alone, or
together with sales by its officers, directors or substantial shareholders, of common stock (or securities convertible into or exercisable for common stock)
equal to 20% or more of the common stock or 20% or more of the voting power outstanding before the issuance for less than the greater of book or market
value; and (3) prior to the issuance of securities when an equity compensation arrangement is made or materially amended, including prior to the issuance
of common stock to the issuer’s officers, director, employees or consultants for less than the greater of book or market value. While French law requires a
French company to obtain prior shareholder approval to issue shares, its shareholders may pre-authorize the company’s board of directors to issue shares
such that shareholder approval is not required at the time of issuance.

The board of directors has established an audit committee and a remuneration and appointments committee, which operate pursuant to rules of procedure
adopted by our board of directors. The board of directors has also established a clinical strategy committee, which

Item 7. Major Shareholders and Related Party Transactions

7.A. Major Shareholders

The following table and accompanying footnotes set forth, as of December 31, 2021, information regarding beneficial ownership of our ordinary shares by:

•

•

•

•

each person, or group of affiliated persons, known by us to beneficially own more than 5% of our ordinary shares;

each of our executive officers;

each of our directors; and

all of our executive officers and directors as a group.

100

Beneficial ownership is determined according to the rules of the SEC and generally means that a person has beneficial ownership of a security if he, she or
it possesses sole or shared voting or investment power of that security, including free shares that vest within 60 days of December 31, 2021 and options and
warrants  that  are  currently  exercisable  or  exercisable  within  60  days  of  December  31,  2021.  Shares  subject  to  free  shares  that  vest  within  60  days  of
December 31, 2021 and shares subject to warrants currently exercisable or exercisable within 60 days of December 31, 2021 are deemed to be outstanding
for  computing  the  percentage  ownership  of  the  person  holding  these  free  shares  and  warrants  and  the  percentage  ownership  of  any  group  of  which  the
holder is a member, but are not deemed outstanding for computing the percentage of any other person.

Except  as  indicated  by  the  footnotes  below,  we  believe,  based  on  the  information  furnished  to  us,  that  the  persons  named  in  the  table  below  have  sole
voting  and  investment  power  with  respect  to  all  shares  shown  that  they  beneficially  own,  subject  to  community  property  laws  where  applicable.  The
information does not necessarily indicate beneficial ownership for any other purpose, including for purposes of Sections 13(d) and 13(g) of the Exchange
Act.

Our calculation of the percentage of beneficial ownership is based on 31,018,553 of our ordinary shares (including ordinary shares in the form of ADSs)
outstanding as of December 31, 2021. Unless otherwise indicated, the address of each beneficial owner listed in the table below is c/o ERYTECH Pharma
S.A., 60 Avenue Rockefeller, 69008 Lyon, France.

does not include holders whose shares may be held in trust by other entities.

We have engaged in the following transactions with our directors, executive officers and holders of more than five percent (5%) of our outstanding voting

Agreements with Our Directors and Executive Officers

Severance Pay

On May 24, 2013, the board of directors approved terms for severance pay to be awarded under certain conditions to our then-executive officers, which
included Gil Beyen, our Chief Executive Officer. The agreement provides that, in the event of expiration of the executive’s term of office (except where
renewal is rejected by the executive) or in the event of revocation (unless the executive has been revoked for gross negligence or willful misconduct as that
term  is  defined  by  the  labor  chamber  of  the  French  Supreme  Court),  the  executive  is  entitled  to  severance  equal  to  12  times  the  average  of  monthly
remuneration (bonuses included) received during the 12 months preceding the revocation decision or the expiration of the executive’s term of office. The
payment of the compensation shall be subject to the performance of the following conditions: (i) respect of our company’s budget and expenditures and
(ii)  at  least  one  of  the  following  conditions:  (a)  an  agreement  of  collaboration  or  a  current  license,  and  (b)  one  product  in  an  active  phase  of  clinical
development by the company. No related expense has been recorded to date.

Executive Employment Agreement with Gil Beyen

Effective April 1, 2019, we and our U.S. subsidiary, ERYTECH Pharma, Inc., entered into an executive employment agreement with Mr. Beyen, or the
Executive Employment Agreement, that provides for the terms of his employment and compensation as President of ERYTECH Pharma, Inc., including an
annual base salary and variable compensation in an amount up to 50% of his base salary, based upon achievement of specified performance objectives. The
Executive Employment Agreement also provides for severance pay in specified situations. In the event of Mr. Beyen’s termination without “cause,” he will
be  entitled  to  an  amount  equal  to  12  times  the  average  of  monthly  remuneration  (bonuses  included)  received  during  the  12  months  preceding  his
termination, subject to certain specified performance conditions. Mr. Beyen will also be entitled to these severance benefits (with no duplication) if Mr.
Beyen is

102

terminated without “cause” or resigns for “good reason” within 12 months following a change of control of our company. Any severance payments paid to
Mr.  Beyen  under  the  Executive  Employment  Agreement  are  conditioned  on  Mr.  Beyen  executing  a  release.  Pursuant  to  an  Employee  Confidential
Information  and  Invention  Assignment  Agreement  attached  to  his  Executive  Employment  Agreement,  upon  voluntary  termination  or  termination  for
”cause,” for a period of 12 months, Mr. Beyen cannot seek employment in any business in which we are engaged or plans to be engaged, or service that we
provide or have plans to provide.

Employment Agreements with Eric Soyer

In September 2015, we entered into employment agreement with Mr. Soyer. This employment agreement provides for an annual base salary and variable
compensation  in  amounts  up  to  35%  of  the  executive’s  current  base  salaries,  based  upon  achievement  of  specified  performance  objectives.  This
employment agreement also provide for severance pay in specified situations. In the event of the executive’s termination in the absence of gross negligence
or willful misconduct, the executive will be entitled to an amount equal to six months’ base salary, plus an additional three months’ base salary for each full
year such executive has worked for us, up to a maximum of 12 months’ base salary in total, including any additional indemnity as provided for by French
law.  In  connection  with  a  change  of  control  of  our  company,  if  the  executive  is  terminated  in  the  absence  of  gross  negligence  or  willful  misconduct  or
resigns pursuant to suffering a diminution of the executive’s job duties, or in the event of a mutually agreed termination (rupture conventionnelle) under
French law, such executive will be entitled to an amount equal to 12 times the average of monthly remuneration, including bonuses, received during the 12
months preceding the termination. If a change of control of our company occurs within 24 months of the granting of bonus shares, such executive will be
entitled to an amount intended to compensate for the potential loss of compensation in the event of cancellation of bonus shares granted or for the potential
loss of favorable tax treatment in the event of the sale of such shares, in the context of this change of control. This agreement also provide for a 18-month
non-compete clause, whereby the executive is entitled to an amount equal to 33% of his average monthly remuneration over the last twelve months.

Employment Agreements with Françoise Horand, Anne-Cécile Fumey and Brian Schwab

In October 2008, February 2016 and January 2020, respectively, we entered into employment agreements with Mrs. Horand, Mrs. Fumey and Mr. Schwab.

Each  employment  agreement  provides  for  an  annual  base  salary  and  variable  compensation  in  amounts  ranging  from  20%  to  35%  of  the  current  base
salaries, based upon achievement of specified performance objectives. These employment agreements do not provide any additional termination indemnity
other  than  the  one  provided  for  by  French  law.  Mrs.  Horand  and  Mr.  Schwab’s  agreements  provide  for  a  18-month  non-compete  clause,  whereby  Mrs.
Horand and Mr. Schwab are entitled to an amount equal to 33% of their average monthly remuneration over the last three months.

Employment Agreement with Iman El-Hariry

In June 2015, our U.S. subsidiary, ERYTECH Pharma, Inc., entered into an employment agreement with Dr. El-Hariry that provides for an annual base
salary and variable compensation in an amount up to 35% of her base salary, based upon achievement of specified performance objectives. This variable
amount was increased from 35% to 40% of her base salary in January 2019. The agreement also provides for severance pay in specified situations. In the
event of Dr. El-Hariry’s termination without cause (as defined in Dr. El-Hariry’s employment agreement), she will be entitled to an amount equal to six
months’ base salary, plus an additional three months’ base salary for each full year she has worked for us, up to a maximum of 12 months’ base salary in
total. If Dr. El-Hariry resigns as a result of (i) a diminution of her job duties, (ii) a change in reporting or (iii) a relocation, she will be entitled to an amount
up to 12 months’ base salary compensation depending upon the length of her employment with us. In connection with a change of control, if Dr. El-Hariry
is terminated within 12 months (a) by us, (b) by mutual agreement or (c) by her decision to resign after receiving an offer that is not at least equivalent to
her position prior to the change in control, she will be entitled to a lump sum payment equal to one year’s salary plus bonus (under the condition that she
would  not  be  eligible  for  the  other  severance  benefits  described  above).  Upon  termination  for  any  reason,  our  company  may  request  Dr.  El-Hariry  to
execute a non-competition agreement for a period of 12 months, whereby Dr. El-Hariry will be entitled to severance pay.

Employment Agreement with Stewart Craig

In November 2020, our U.S. subsidiary, ERYTECH Pharma, Inc., entered into an employment agreement with Dr. Craig that provides for an annual base
salary and variable compensation in an amount up to 35% of his base salary, based upon achievement of specified performance objectives. The agreement
also  provides  for  severance  pay  in  specified  situations.  In  the  event  of  Dr.  Craig’s  termination  without  cause  (as  defined  in  Dr.Craig’s  employment
agreement), he will be entitled to an amount equal to six months’ base salary during the first 24 months of employment, plus an additional three months’
base salary for each full year he has worked for us, up to a maximum of 12 months’ base salary in total. In connection with a change of control, if Dr. Craig
is terminated within 12 months (a) by us, (b) by mutual agreement or (c) by his decision to resign after receiving an offer that is not at least equivalent to
his position prior to

103

the change in control, he will be entitled to a lump sum payment equal to one year’s salary plus bonus (under the condition that he would not be eligible for
the  other  severance  benefits  described  above).  Upon  termination  for  any  reason,  our  company  may  request  Dr.  Craig  to  execute  a  non-competition
agreement for a period of 12 months, whereby Dr. Craig will be entitled to severance pay.

Employment Agreement with Jérôme Bailly

In January 2007, we entered into an employment agreement with Dr. Bailly, which was amended as of January 2018. He is entitled to an annual base salary
set  at  €170,000,  and  variable  compensation,  in  an  amount  up  to  25%  of  his  base  salary,  upon  achievement  of  specified  performance  objectives.  This
variable amount was increased from 25% to 30% of his base salary in January 2019 and from 30% to 35% of his base salary in January 2021. If a change of
control of our company occurs within 24 months of the granting of bonus shares, Dr. Bailly will be entitled to an amount intended to compensate for the
potential loss of compensation in the event of cancellation of bonus shares granted or for the potential loss of favorable tax treatment in the event of the sale
of such shares.

His employment agreements also provide for severance pay in specified situations. In the event of the termination in the absence of gross negligence or
willful misconduct, Mr. Bailly will be entitled to an amount equal to six months’ base salary, plus an additional three months’ base salary for each full year
such executive has worked for us, up to a maximum of 12 months’ base salary in total, including any additional indemnity as provided for by French law.
In  connection  with  a  change  of  control  of  our  company,  if  Mr.  Bailly  is  terminated  in  the  absence  of  gross  negligence  or  willful  misconduct  or  resigns
pursuant to suffering a diminution of the executive’s job duties, or in the event of a mutually agreed termination (rupture conventionnelle) under French
law, Mr. Bailly will be entitled to an amount equal to 12 times the average of monthly remuneration, including bonuses, received during the 12 months
preceding the termination. The payment of the compensations shall be subject to the performance of the following conditions: (i) respect of our company’s
budget and expenditures and (ii) at least one of the following conditions: (a) an agreement of collaboration or a current license, and (b) one product in an
active phase of clinical development by the company.

If a change of control of our company occurs within 24 months of the granting of bonus shares, such executive will be entitled to an amount intended to
compensate for the potential loss of compensation in the event of cancellation of bonus shares granted or for the potential loss of favorable tax treatment in
the event of the sale of such shares, in the context of this change of control.

His employment agreement also provides for a 18-month non-compete clause, whereby Mr. Bailly is entitled to an amount equal to 33% of his average
monthly remuneration over the last three months.

The training convention with Mr. Jérôme Bailly ended on July 31, 2021.

Director and Executive Officer Compensation

See “Item 6.B—Compensation” for information regarding compensation of directors and executive officers.

Equity Awards

See “Item. 7A—Major Shareholders” for information regarding equity awards to our executive officers.

Bonus Plans

All our executive officers are entitled to a bonus ranging between 25% and 50% based on yearly objectives determined by our board of directors upon
recommendation of our remuneration and appointments committee.

Indemnification Agreements

We have entered into indemnification agreements with each of our directors and some of our executive officers. See “Item. 6B—Limitations on Liability
and Indemnification Matters.”

104

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the
foregoing provisions, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act
and is therefore unenforceable.

Related-Party Transactions Policy

We comply with French law regarding approval of transactions with related parties. We have adopted a related person transaction policy that sets forth our
procedures for the identification, review, consideration and approval or ratification of related person transactions. The policy became effective in November
2017 upon the closing of our global offering and was subsequently amended in March 2020 to meet the new French law requirements arising from Law no.
2019-486 of May 22, 2019 (Pacte law) as described below.

For  purposes  of  our  policy  only,  a  related  person  transaction  is  defined  as  (i)  any  transaction,  arrangement  or  relationship  (or  any  series  of  similar
transactions,  arrangements  or  relationships)  in  which  we  and  any  related  person  are,  were  or  will  be  participants  in  and  the  amount  involved  exceeds
$120,000, or (ii) any agreement or similar transaction under French law which falls within the scope of Article L. 225-38 of the French Commercial Code.
A  related  person  is  any  executive  officer,  director  or  beneficial  owner  of  more  than  5%  of  any  class  of  our  voting  securities,  including  any  of  their
immediate family members and any entity owned or controlled by such persons. Article L. 225-38 of the French Commercial Code covers any agreement
or similar transaction entered into directly or indirectly between (i) the company and a corporate officer, a director, a shareholder holding more than 10% of
the company’s voting rights or, if such shareholder is a corporate entity, its controlling shareholder within the meaning of Article L. 233-3 of the French
Commercial Code or between (ii) the company and another firm if a corporate officer or director of the company is the owner, a fully liable shareholder, a
corporate officer, a director or a member of that other firm’s supervisory board or, more generally, a person in any way involved in its management.

Under the policy, if a transaction has been identified as a related person transaction, including any transaction that was not a related person transaction
when originally consummated or any transaction that was not initially identified as a related person transaction prior to consummation, our management
must  present  information  regarding  the  related  person  transaction  to  our  board  of  directors  for  review,  consideration  and  approval  or  ratification.  The
presentation must include a description of, among other things, the material facts, the interests, direct and indirect, of the related persons, the benefits to us
of the transaction and whether the transaction is on terms that are comparable to the terms available to or from, as the case may be, an unrelated third party
or to or from employees generally. Under the policy, we will collect information that we deem reasonably necessary from each director, executive officer
and, to the extent feasible, significant shareholder to enable us to identify any existing or potential related-person transactions and to effectuate the terms of
the policy. Our General Counsel will conduct an assessment of our related person transactions, notably to determine whether such transactions relate to
current operations and entered into under normal conditions (portant sur des opérations courantes et conclues à des conditions normales), which will be
monitored at least annually by our audit committee.

In addition, under our Code of Business Conduct and Ethics, our employees and directors have an affirmative responsibility to disclose any transaction or
relationship that reasonably could be expected to give rise to a conflict of interest.

In considering related person transactions, our board of directors will take into account the relevant available facts and circumstances including, but not
limited to:

•

•

•

•

the risks, costs and benefits to us;

the impact on a director’s independence in the event that the related person is a director, immediate family member of a director or an entity with
which a director is affiliated;

the availability of other sources for comparable services or products; and

the terms available to or from, as the case may be, unrelated third parties or to or from employees generally.

The policy requires that, in determining whether to approve, ratify or reject a related person transaction, our board of directors must consider, in light of
known circumstances, whether the transaction is in, or is not inconsistent with, our best interests and those of our shareholders, as our board of directors
determines in the good faith exercise of its discretion.

Consolidated Financial Statements

Dividend Distribution Policy

We  have  never  declared  or  paid  any  cash  dividends  on  our  ordinary  shares.  We  do  not  anticipate  paying  cash  dividends  on  our  equity  securities  in  the
foreseeable future and intend to retain all available funds and any future earnings for use in the operation and expansion of our business, given our state of
development.

Subject to the requirements of French law and our bylaws, dividends may only be distributed from our distributable profits, plus any amounts held in our
available reserves which are reserves other than legal and statutory and revaluation surplus. See “Item 10. B—Memorandum and Articles of Association”
for  further  details  on  the  limitations  on  our  ability  to  declare  and  pay  dividends.  Dividend  distributions,  if  any  in  the  future,  will  be  made  in  euros  and
converted into U.S. dollars with respect to the ADSs, as provided in the amended and restated deposit agreement.

Legal Proceedings

From time to time we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. We are not presently
a party to any legal proceedings that, if determined adversely to us, would individually or taken together have a material adverse effect on our business,
results  of  operations,  financial  condition  or  cash  flows.  Regardless  of  the  outcome,  litigation  can  have  an  adverse  impact  on  us  because  of  defense  and
settlement costs, diversion of management resources and other factors.

Corporate Purpose (Article 3 of the Bylaws)

The Company’s corporate purpose in France and abroad includes the research, manufacturing, importation, distribution and marketing of investigational
drugs, devices and medical equipment, and the provision of advisory services associated with these activities. The Company is authorized to engage in all
financial, commercial, industrial, civil, property or security-related transactions that directly or indirectly relate to accomplishing the purposes stated above.

The Company may act directly or indirectly and do all these operations in all countries, for or on behalf of third parties, either alone or with partnership
with third parties, association, group or creation of new companies, contribution, sponsorship, subscription, purchase of shares or rights, mergers, alliances,
undeclared partnership or taking or giving in lease or in management of all property and rights or otherwise.

Directors (Articles 17-22 of the Bylaws)

Duties of the Board. Except for powers given to the Company’s shareholders by law and within the limit of the corporate purpose, the Company’s board of
directors is responsible for all matters relating to the successful operations of the Company, including but not limited to, social and environmental issues
associated with the Company’s activities, and, through its resolutions, governs matters involving the company.

Appointment and Term. The Company’s board of directors must be composed of at least three members, but may not exceed 18 members, subject to the
dispensation established by law in the event of merger. In appointing and electing directors, the Company seeks a balanced representation of women and
men. The term of a director is 3 years, and directors may be re-elected at the Company’s annual ordinary share meetings; however, a director over the age
of 75 may not be appointed if such appointment would result in the number of directors over the age of 75 constituting more than one-third of the board.
The number of directors who are also the Company’s employees cannot exceed one-third of the board. Directors may be natural persons or legal entities
except for the chairman of the board who must be a natural person. Legal entities appointed to the board must designate a permanent representative. If a
director dies or resigns between annual meetings, the board may appoint a temporary director to fill the vacancy, subject to ratification at the next ordinary
general meeting, or, if such vacancy results in a number of directors below three, the board must call an ordinary general meeting to fill the vacancy. If a
director is absent at more than four consecutive meetings or placed with guardians, he or she will be deemed to have automatically resigned.

Organization. The board must elect a chairman from among the board members. The chairman must be a natural person, age 75 or younger, and may be
removed by the board at any time. The board may also elect a natural person as vice president to preside in the chairman’s absence and may designate up to
two non-voting board observers.

Deliberations. At least half of the number of directors in office must be present to constitute a quorum. Decisions are made by a majority of the directors
present  or  represented  and,  if  there  is  a  tie,  the  vote  of  the  chairman  will  carry  the  decision.  Meetings  may  be  held  as  often  as  required;  however,  the
chairman is required to call a meeting with a determined agenda upon the request of at least one-third of the directors if the board has not met for more than
two months. French law and the Company’s charter and bylaws allow directors to attend meetings in person or, to the extent permitted by applicable law
and with specified exceptions in the Company’s bylaws, by videoconference or other telecommunications arrangements. The board of directors can also
make decisions by way of written consultation under the conditions provided by law.

Directors’  Voting  Powers  on  Proposal,  Arrangement  or  Contract  in  which  any  Director  is  Materially  Interested.  Under  French  law,  any  agreement
entered into, directly or through an intermediary, between the Company and any director that is not entered into in the ordinary course of the Company’s
business and upon standard market terms is subject to the prior authorization of the board of directors. The interested director cannot vote on such decision.
The  same  provision  applies  to  agreements  between  the  Company  and  another  company,  except  where  such  company  is  the  Company’s  wholly  owned
subsidiary,  if  one  of  the  Company’s  directors  is  the  owner  or  a  general  partner,  manager,  director,  general  manager  or  member  of  the  executive  or
supervisory board of the other company, as well as to agreements in which one of the Company’s directors has an indirect interest.

Directors’ Compensation. Director compensation for attendance at board meetings is determined at the annual ordinary general meeting. The general
meeting may allocate an annual fixed sum and the board of directors allocates this sum among its members as it sees fit. In addition, the board of directors
may allocate exceptional compensation (rémunération exceptionnelle) for missions or mandates entrusted to its members, for example as member or chair
of one or more board committees, this remuneration is subject to the provisions regarding related-parties agreements. At the Company’s combined general
meetings of shareholders held on June 28, 2018, June 21, 2019, June 26, 2020, shareholders set the total annual attendance fees to be distributed among
non-employee directors at €280 thousand for 2018, €400 thousand for 2019 and €425 thousand for 2020 and 2021.

107

Board  of  Directors’  Borrowing  Powers.  There  are  currently  no  limits  imposed  on  the  amounts  of  loans  or  borrowings  that  the  board  of  directors  may
approve.

Directors’ Share Ownership Requirements. The Company’s directors are not required to own any of the Company’s shares.

Shareholder rights

Rights, Preferences and Restrictions Attaching to Ordinary Shares (Articles 9, 16, 30, 33 and 34 of the Bylaws)

Dividends. The Company may only distribute dividends out of the Company’s distributable profits, plus any amounts held in the Company’s reserves that
the shareholders decide to make available for distribution, other than those reserves that are specifically required by law.

“Distributable Profits” consist of the Company’s statutory net profit in each fiscal year, calculated in accordance with accounting standards applicable in
France, as increased or reduced by any profit or loss carried forward from prior years, less any contributions to the reserve accounts pursuant to French law.

Legal Reserve. Pursuant to French law, the Company must allocate 5% of the Company’s statutory net profit for each year to the Company’s legal reserve
fund before dividends may be paid with respect to that year. Funds must be allocated until the amount in the legal reserve is equal to 10% of the aggregate
par value of the issued and outstanding share capital.

Approval of Dividends. Pursuant to French law, the Company’s board of directors may propose a dividend for approval by the shareholders at the annual
ordinary general meeting.

Upon recommendation of the Company’s board of directors, the Company’s shareholders may decide to allocate all or part of any distributable profits to
special or general reserves, to carry them forward to the next fiscal year as retained earnings or to allocate them to the shareholders as dividends. However,
dividends may not be distributed when the Company’s net assets are or would become as a result of such distribution lower than the amount of the share
capital plus the amount of the legal reserves which, under French law, may not be distributed to shareholders. The amount of the Company’s share capital
plus the amount of the Company’s legal reserves which may not be distributed was equal to €2,641,238.90 at June 25, 2021.

The Company’s board of directors may distribute interim dividends after the end of the fiscal year but before the approval of the financial statements for the
relevant  fiscal  year  when  the  interim  balance  sheet,  established  during  such  year  and  certified  by  an  auditor,  reflects  that  the  Company  has  earned
distributable profits since the close of the last financial year, after recognizing the necessary depreciation and provisions and after deducting prior losses, if
any, and the sums to be allocated to reserves, as required by law or the bylaws, and including any retained earnings. The amount of such interim dividends
may not exceed the amount of the profit so defined.

Distribution  of  Dividends.  Dividends  are  distributed  to  shareholders  pro  rata  according  to  their  respective  holdings  of  shares.  In  the  case  of  interim
dividends,  distributions  are  made  to  shareholders  on  the  date  set  by  the  Company’s  board  of  directors  during  the  meeting  in  which  the  distribution  of
interim dividends is approved. The actual dividend payment date is decided by the shareholders at an ordinary general shareholders’ meeting or by the
Company’s board of directors in the absence of such a decision by the shareholders. Shareholders that own shares on the actual payment date are entitled to
the dividend.

Shareholders  may  be  granted  an  option  to  receive  dividends  in  cash  or  in  shares,  in  accordance  with  legal  conditions.  The  conditions  for  payment  of
dividends in cash shall be set at the shareholders’ meeting or, failing this, by the board of directors.

Timing of Payment. Pursuant to French law, dividends must be paid within a maximum of nine months after the close of the relevant fiscal year, unless
extended by court order. Dividends not claimed within five years after the payment date shall be deemed to expire and revert to the French state.

Voting Rights. Each share shall entitle its holder to vote and be represented in the shareholders’ meetings in accordance with the provisions of French law
and  of  the  Company’s  bylaws.  Ownership  of  one  share  implies,  ipso  jure,  adherence  to  the  Company’s  bylaws  and  the  decisions  of  the  shareholders’
meeting.

In general, each shareholder is entitled to one vote per share at any general shareholders’ meeting. Pursuant to the Company’s bylaws, however, a double
voting right is attached to each registered share which is held in the name of the same shareholder for at least two years. Under French law, ordinary bearer
shares are not eligible for double voting rights. Purchasers of ADSs or of ordinary shares deposited with the depositary to receive ADSs, will be unlikely to
meet the requirements to have double voting rights.

108

Under  French  law,  treasury  shares  or  shares  held  by  entities  controlled  by  the  Company  are  not  entitled  to  voting  rights  and  do  not  count  for  quorum
purposes.

Rights to Share in the Company’s Profit. Each share entitles its holder to a portion of the corporate profits and assets proportional to the amount of share
capital represented thereby.

Rights to Share in the Surplus in the Event of Liquidation. If the Company is liquidated, any assets remaining after payment of the debts, liquidation
expenses and all of the remaining obligations will first be used to repay in full the par value of the Company’s shares. Any surplus will be distributed pro
rata among shareholders in proportion to the number of shares respectively held by them, taking into account, where applicable, of the rights attached to
shares of different classes.

Repurchase and Redemption of Shares. Under French law, the Company may acquire its own shares. Such acquisition may be challenged on the ground of
market abuse regulations. However, Regulation (EU) No. 596/2014 of April 16, 2014 provides for safe harbor exemptions when the acquisition is made for
one of the following purposes:

• to decrease the Company’s share capital, provided that such a decision is not driven by losses and that a purchase offer is made to all shareholders
on  a  pro  rata  basis,  with  the  approval  of  the  shareholders  at  an  extraordinary  general  meeting;  in  this  case,  the  shares  repurchased  must  be
cancelled within one month from the expiry of the purchase offer;

• to meet obligations arising from debt securities that are exchangeable into equity instruments;

•  to  provide  shares  for  distribution  to  employees  or  managers  under  a  profit-sharing,  free  share  or  share  option  plan;  in  this  case  the  shares

repurchased must be distributed within 12 months from their repurchase failing which they must be cancelled; or

• the Company benefit from a simple exemption when the acquisition is made under a liquidity contract complying with the general regulations of,

and market practices accepted by the French Financial Markets Authority (AMF).

All other purposes, and especially share buy-backs made for external growth operations in pursuance of Article L. 20-10-62 of the French Commercial
Code, while not forbidden, must be pursued in strict compliance of market manipulation and insider dealing rules.

Under the Market Abuse Regulation 596/2014 of August 16, 2014 (MAR) and in accordance with the General Regulations of the AMF, a corporation shall
report  to  the  competent  authority  of  the  trading  value  on  which  the  shares  have  been  admitted  to  trading  or  are  traded,  no  later  than  by  the  end  of  the
seventh daily market session following the date of the execution of the transaction, all the transactions relating to the buy-back program, in a detailed form
and in an aggregated form.

No  such  repurchase  of  shares  may  result  in  the  Company  holding,  directly  or  through  a  person  acting  on  the  Company’s  behalf,  more  than  10%  of  the
Company’s issued share capital. Shares repurchased by the Company continue to be deemed “issued” under French law but are not entitled to dividends or
voting rights so long as the Company holds them directly or indirectly, and the Company may not exercise the preemptive rights attached to them.

Sinking Fund Provisions. The Company’s bylaws do not provide for any sinking fund provisions.

Liability to Further Capital Calls. Shareholders are liable for corporate liabilities only up to the par value of the shares they hold; they are not liable to
further capital calls.

Requirements  for  Holdings  Exceeding  Certain  Percentages.  None,  except  as  described  below  under  the  sections  of  this  exhibit  titled  “Declaration  of
Crossing of Ownership Thresholds (Article 9 of the Bylaws)” and “Form, Holding and Transfer of Shares (Articles 13 and 15 of the Bylaws)—Ownership
of Shares by Non-French Persons.”

Actions Necessary to Modify Shareholders’ Rights

Shareholders’  rights  may  be  modified  as  allowed  by  French  law.  Only  the  extraordinary  shareholders’  meeting  is  authorized  to  amend  any  and  all
provisions of the Company’s bylaws. It may not, however, increase shareholder commitments without the prior approval of each shareholder.

Special Voting Rights of Warrant Holders

Under French law, the holders of warrants of the same class (i.e., warrants that were issued at the same time and with the same rights), including founder’s
warrants, are entitled to vote as a separate class at a general meeting of that class of warrant holders under certain circumstances, principally in connection
with any proposed modification of the terms and conditions of the class of warrants or any proposed issuance of preferred shares or any modification of the
rights of any outstanding class or series of preferred shares.

109

Rules for Admission to and Calling Annual Shareholders’ Meetings and Extraordinary Shareholders’ Meetings (Section IV of the Bylaws)

Access  to,  Participation  in  and  Voting  Rights  at  Shareholders’  Meetings.  Shareholders’  meetings  are  composed  of  all  shareholders,  regardless  of  the
number of shares they hold. Each shareholder has the right to attend the meetings and participate in the discussions (1) personally; (2) by granting proxy to
any individual or legal entity of his choosing; (3) by sending a proxy to the Company without indication of the mandate; (4) by voting by correspondence;
or  (5)  at  the  option  of  the  board  of  directors  at  the  time  the  meeting  is  called,  by  videoconference  or  another  means  of  telecommunication,  including
internet,  in  accordance  with  applicable  laws  that  allow  identification.  The  board  of  directors  organizes,  in  accordance  with  legal  and  regulatory
requirements, the participation and vote of these shareholders at the meeting, assuring, in particular, the effectiveness of the means of identification.

Participation in shareholders’ general meetings, in any form whatsoever, is subject to registration or registration of shares under the conditions and time
limits provided for applicable laws.

The final date for returning voting ballots by correspondence is set by the board of directors and disclosed in the notice of meeting published in the French
Journal of Mandatory Statutory Notices, or BALO (Bulletin des Annonces Légales Obligatoires). This date cannot be earlier than three days prior to the
meeting unless otherwise provided in the bylaws. The Company’s bylaws provide that the board of directors has the option to accept the voting ballots by
correspondence beyond the limit set by applicable laws.

A shareholder who has voted by correspondence will no longer be able to participate directly in the meeting or to be represented. In the case of returning
the proxy form and the voting by correspondence form, the proxy form is taken into account, subject to the votes cast in the voting by correspondence
form.

A shareholder may be represented at meetings by any individual or legal entity by means of a proxy form which the Company sends to such shareholder
either at the shareholder’s request or at the Company’s initiative. A shareholder’s request for a proxy form must be received at the registered office at least
five days before the date of the meeting. The proxy is only valid for a single meeting or for successive meetings convened with the same agenda. It can also
be granted for two meetings, one ordinary, and the other extraordinary, held on the same day or within a period of fifteen days.

A shareholder may vote by correspondence by means of a voting form, which the Company sends to such shareholder either at the shareholder’s request or
at the Company’s initiative, or which the Company includes in an appendix to a proxy voting form under the conditions provided for by current laws and
requirements. A shareholder’s request for a voting form must be received at the registered office at least six days before the date of the meeting. The voting
form is also available on the Company’s website at least 21 days before the date of the meeting. The voting form must be recorded by the Company three
days prior to the shareholders’ meeting, in order to be taken into consideration. The voting by correspondence form addressed by a shareholder is only valid
for a single meeting or for successive meetings convened with the same agenda.

To better understand the voting rights of the ADSs, ADS holders should carefully read the section in this exhibit titled “II. American Depositary Shares—
Voting Rights.” .

Notice of Annual Shareholders’ Meetings. Shareholders’ meetings are convened by the Company’s board of directors, or, failing that, by the statutory
auditors, or by a court appointed agent or liquidator in certain circumstances. Meetings are held at the Company’s registered offices or at any other location
indicated in the meeting announcement (avis de réunion). A meeting announcement is published in the BALO at least 35 days prior to a meeting, as well as
on the Company’s website at least 21 days prior to the meeting. In addition to the particulars relative to the Company, it indicates, notably, the meeting’s
agenda and the draft resolutions that will be presented. The requests for recording of issues or draft resolutions on the agenda must be addressed to the
Company under the conditions provided for in the current legislation.

Subject to special legal provisions, the convening notice (avis de convocation) is sent out at least 15 days prior to the date of the meeting, by means of a
notice inserted both in a legal announcement bulletin of the registered office department and in the BALO. Further, the holders of registered shares for at
least a month at the time of the latest of the insertions of the convening notice shall be summoned individually, by regular letter (or by registered letter if
they  request  it  and  include  an  advance  of  expenses)  sent  to  their  last  known  address.  This  notice  may  also  be  transmitted  by  electronic  means  of
telecommunication,  in  lieu  of  any  such  mailing,  to  any  shareholder  requesting  it  beforehand  by  registered  letter  with  acknowledgment  of  receipt  in
accordance with legal and regulatory requirements, specifying his e-mail address. The latter may at any time expressly request by registered letter to the
Company with acknowledgment of receipt that the aforementioned means of telecommunication should be replaced in the future by a mailing.

The convening notice must also indicate the conditions under which the shareholders may vote by correspondence and the places and conditions in which
they can obtain voting forms by mail.

110

The convening notice may be addressed, where appropriate, with a proxy form and a voting by correspondence form, under the conditions specified in the
Company’s  bylaws,  or  with  a  voting  by  correspondence  form  alone,  under  the  conditions  specified  in  the  Company’s  bylaws.  When  the  shareholders’
meeting cannot deliberate due to the lack of the required quorum, the second meeting must be called at least ten days in advance in the same manner as
used for the first notice.

Agenda and Conduct of Annual Shareholders’ Meetings. The agenda of the shareholders’ meeting shall appear in the convening notice of the meeting
and is set by the author of the notice. The shareholders’ meeting may only deliberate on the items on the agenda except for the removal of directors and the
appointment of their successors which may be put to vote by any shareholder during any shareholders’ meeting. Pursuant to French law and the Company’s
current share capital, one or more shareholders representing 5% of the Company’s share capital may request the inclusion of items or proposed resolutions
on the agenda. Such request must be received at the latest on the 25  day preceding the date of the shareholders’ meeting, and in any event no later than the
20  day following the date of the shareholders’ meeting announcement.

th

th

Shareholders’ meetings shall be chaired by the Chairman of the board of directors or, in his or her absence, by a Deputy Chairman or by a director elected
for  this  purpose.  Failing  that,  the  meeting  itself  shall  elect  a  Chairman.  Vote  counting  shall  be  performed  by  the  two  members  of  the  meeting  who  are
present and accept such duties, who represent, either on their own behalf or as proxies, the greatest number of votes.

Ordinary  Shareholders’  Meeting.  Ordinary  shareholders’  meetings  are  those  meetings  called  to  make  any  and  all  decisions  that  do  not  amend  the
Company’s bylaws. An ordinary meeting shall be convened at least once a year within six months of the end of each fiscal year in order to approve the
annual and consolidated accounts for the relevant fiscal year or, in case of postponement, within the period established by court order. Upon first notice, the
meeting may validly deliberate only if the shareholders present or represented by proxy or voting by mail represent at least one-fifth of the shares entitled
to  vote.  Upon  second  notice,  no  quorum  is  required.  Decisions  are  made  by  a  majority  of  the  votes  cast  by  the  shareholders  present,  or  represented  by
proxy,  or  voting  by  mail.  Abstentions  will  have  the  same  effect  of  a  “no”  vote.  In  addition,  pursuant  to  a  recent  AMF  recommendation,  French  listed
companies may be required to conduct a consultation of the ordinary shareholders meeting prior to the disposal of the majority of their assets, under certain
circumstances. ,

Extraordinary  Shareholders’  Meeting.  The  Company’s  bylaws  may  only  be  amended  by  approval  at  an  extraordinary  shareholders’  meeting.  The
Company’s  bylaws  may  not,  however,  be  amended  to  increase  shareholder  commitments  without  the  approval  of  each  shareholder.  Subject  to  the  legal
provisions governing share capital increases from reserves, profits or share premiums, the resolutions of the extraordinary meeting shall be valid only if the
shareholders present, represented by proxy or voting by mail represent at least one-fourth of all shares entitled to vote upon first notice, or one-fifth upon
second notice. If the latter quorum is not reached, the second meeting may be postponed to a date no later than two months after the date for which it was
initially  called.  Decisions  are  made  by  a  two-thirds  majority  of  the  votes  cast  by  the  shareholders  present,  represented  by  proxy,  or  voting  by  mail.
Abstentions will have the same effect of a “no” vote.

Limitations

Ownership of ADSs or Shares by Non-French Residents

Neither  the  French  Commercial  Code  nor  the  Company’s  bylaws  presently  impose  any  restrictions  on  the  right  of  non-French  residents  or  non-French
shareholders to own and vote shares. However, non-French residents must file a declaration for statistical purposes with the Bank of France (Banque de
France) within twenty working days following the date of certain direct foreign investments in the Company, including any purchase of the Company’s
ADSs. In particular such filings are required in connection with investments exceeding €15,000,000 that lead to the acquisition of at least 10% of the share
capital or voting rights or cross such 10% threshold. Violation of this filing requirement may be sanctioned by five years’ imprisonment and a fine up to
twice the amount of the relevant investment. This amount may be increased fivefold if the violation is made by a legal entity. Moreover, certain foreign
investments in companies incorporated under French laws are subject to the prior authorization from the French Minister of the Economy, where all or part
of the target’s business and activity relate to a strategic sector, such as energy, transportation, public health and telecommunications. etc., pursuant to Law
n°2019-486 (and as from April 1, 2020 pursuant to the decree n°2019-1590). The French government has adapted this foreign investment control procedure
in  France  within  the  context  of  the  ongoing  COVID-19  pandemic  in  two  ways:  (i)  the  inclusion,  by  a  Ministerial  order  (arrêté)  of  April  27,  2020,  of
biotechnologies  in  the  list  of  critical  technologies  and  (ii)  the  addition,  by  a  Decree  (décret)  of  July  22,  2020  as  amended  by  Decree  n°2020-1729  of
December  28,  2020,  of  the  threshold  of  10%  of  voting  rights  of  a  company  subject  to  French  law  whose  securities  are  listed  on  a  stock  exchange  as
triggering the control procedure. The Decree of July 22, 2020, as extended by the Decree n° 2021-1758 of December 22, 2021, currently provides that this
new 10% threshold will be effective until December 31, 2022 and a fast-track review procedure for foreign investments exceeding this threshold.

Foreign Exchange Controls

111

Under  current  French  foreign  exchange  control  regulations  there  are  no  limitations  on  the  amount  of  cash  payments  that  the  Company  may  remit  to
residents of foreign countries. Laws and regulations concerning foreign exchange controls do, however, require that all payments or transfers of funds made
by a French resident to a non-resident such as dividend payments be handled by an accredited intermediary. All registered banks and substantially all credit
institutions in France are accredited intermediaries.

Availability of Preferential Subscription Rights

The  Company’s  shareholders  will  have  the  preferential  subscription  rights  described  under  “Ordinary  Shares—Changes  in  Share  Capital—Preferential
Subscription Right.” Under French law, shareholders have preferential rights to subscribe for cash issues of new shares or other securities giving rights to
acquire additional shares on a pro rata basis. Holders of the Company’s securities in the United States (which may be represented by ADSs) will not be able
to exercise preferential subscription rights for their securities unless a registration statement under the Securities Act is effective with respect to such rights
or an exemption from the registration requirements imposed by the Securities Act is available. The Company may, from time to time, issue new shares or
other  securities  giving  rights  to  acquire  additional  shares  (such  as  warrants)  at  a  time  when  no  registration  statement  is  in  effect  and  no  Securities  Act
exemption is available. If so, holders of the Company’s securities in the United States will be unable to exercise any preferential subscription rights and
their interests will be diluted. The Company is under no obligation to file any registration statement in connection with any issuance of new shares or other
securities. The Company intends to evaluate at the time of any rights offering the costs and potential liabilities associated with registering the rights, as well
as the indirect benefits to the Company of enabling the exercise by holders of shares in the United States and ADS holders of the subscription rights, and
any other factors the Company considers appropriate at the time, and then to make a decision as to whether to register the rights. The Company cannot
guarantee that it will file a registration statement.

For holders of the Company’s ordinary shares represented by ADSs, the depositary may make these rights or other distributions available to ADS holders.
If the depositary does not make the rights available to ADS holders and determines that it is impractical to sell the rights, it may allow these rights to lapse.
In that case, ADS holders will receive no value for them. The section herein titled “II. American Depositary Shares—Dividends and Other Distributions”
explains in detail the depositary’s responsibility in connection with a rights offering. See also “Risk Factors—The right as a holder of ADSs to participate
in any future preferential subscription rights or to elect to receive dividends in shares may be limited, which may cause dilution to the holders of our ADSs”
in the Company’s Annual Report on Form 20-F to which this description is filed as an exhibit.

Provisions Having the Effect of Delaying, Deferring or Preventing a Change in Control of the Company

Provisions contained in the Company’s bylaws and French corporate law could make it more difficult for a third-party to acquire the Company, even if
doing so might be beneficial to the Company’s shareholders. These provisions include the following:

• under French law, the owner of 90% of the share capital or voting rights of a public company listed on a regulated market in a Member State of the
European Union or in a state party to the EEA Agreement, including from the main French Stock Exchange, has the right to force out minority
shareholders following a tender offer made to all shareholders;

• under  French  law,  a  non-resident  of  France  as  well  as  any  French  entity  controlled  by  non-residents  of  France  may  have  to  file  a  declaration  for
statistical purposes with the Bank of France (Banque de France) within 20 working days following the date of certain direct foreign investments in
the Company, including any purchase of the Company’s ADSs. In particular, such filings are required in connection with investments exceeding
€15,000,000  that  lead  to  the  acquisition  of  at  least  10%  of  the  Company’s  share  capital  or  voting  rights  or  cross  such  10%  threshold.  See
“Limitations Affecting Shareholders of a French Company;”

•

under French law, certain investments in a French company relating to certain strategic industries, including biotechnologies, by individuals or
entities not residents in a Member State of the European Union are subject to prior authorization of the Ministry of Economy pursuant to Law
n°2019-486 (and as from April 1, 2929 pursuant to the decree n°2019-1580 of December 31, 2019, as amended by decree (arrêté) of April 27,
2020). See “Limitations Affecting Shareholders of a French Company;”

• a merger (i.e., in a French law context, a share for share exchange following which the Company’s company would be dissolved into the acquiring
entity  and  the  Company’s  shareholders  would  become  shareholders  of  the  acquiring  entity)  of  the  Company’s  company  into  a  company
incorporated in the European Union would require the approval of the Company’s board of directors as well as a two-thirds majority of the votes
cast by the shareholders present, represented by proxy or voting by mail at the relevant meeting;

•  a  merger  of  the  Company’s  company  into  a  company  incorporated  outside  of  the  European  Union  would  require  100%  of  the  Company’s

shareholders to approve it;

112

•

under French law, a cash merger is treated as a share purchase and would require the consent of each participating shareholder;

•  the  Company’s  shareholders  have  granted  and  may  grant  in  the  future  the  Company’s  board  of  directors  broad  authorizations  to  increase  the
Company’s share capital or to issue additional ordinary shares or other securities, such as warrants, to the Company’s shareholders, the public or
qualified investors, including as a possible defense following the launching of a tender offer for the Company’s shares;

• the Company’s shareholders have preferential subscription rights on a pro rata basis on the issuance by the Company of any additional securities for
cash  or  a  set-off  of  cash  debts,  which  rights  may  only  be  waived  by  the  extraordinary  general  meeting  (by  a  two-thirds  majority  vote)  of  the
Company’s shareholders or on an individual basis by each shareholder;

• the Company’s board of directors has the right to appoint directors to fill a vacancy created by the resignation or death of a director for the remaining
duration of such directors' term of office and subject to the approval by the shareholders of such appointment at the next shareholders’ meeting,
which prevents shareholders from having the sole right to fill vacancies on the Company’s board of directors ;

• the Company’s board of directors can be convened by its chairman or its managing director, if any, or, when no board meeting has been held for more

than two consecutive months, by directors representing at least one third of the total number of directors;

•  the  Company’s  board  of  directors  meetings  can  only  be  regularly  held  if  at  least  half  of  the  directors  attend  either  physically  or  by  way  of

videoconference or teleconference enabling the directors’ identification and ensuring their effective participation in the board’s decisions;

• the Company’s shares are nominative or bearer, if the legislation so permits, according to the shareholder’s choice;

•  approval  of  at  least  a  majority  of  the  votes  cast  by  shareholders  present,  represented  by  a  proxy,  or  voting  by  mail  at  the  relevant  ordinary

shareholders’ general meeting is required to remove directors with or without cause;

• advance notice is required for nominations to the board of directors or for proposing matters to be acted upon at a shareholders’ meeting, except that

a vote to remove and replace a director can be proposed at any shareholders’ meeting without notice;

• the Company’s bylaws can be changed in accordance with applicable laws;

• the crossing of certain thresholds has to be disclosed and can impose certain obligations; see the section of this exhibit titled “Declaration of Crossing

of Ownership Thresholds (Article 9 of the Bylaws);”

•  transfers  of  shares  shall  comply  with  applicable  insider  trading  rules  and  regulations,  and  in  particular  with  the  Market  Abuse  Directive  and

Regulation dated April 16, 2014; and

• pursuant to French law, the sections of the bylaws relating to the number of directors and election and removal of a director from office may only be
modified by a resolution adopted by two-thirds of the votes of the Company’s shareholders present, represented by a proxy or voting by mail at the
meeting.

Disclosure of shareholdings

Declaration of Crossing of Ownership Thresholds (Article 9 of the Bylaws)

Any individual or legal entity referred to in Articles L. 233-7, L. 233-9 and L. 223-10 of the French Commercial Code coming to directly or indirectly own,
or cease to own, alone or in concert, a number of shares representing a fraction of the Company’s capital or voting rights greater or equal to 5%, 10%, 15%,
20%, 25%, 30%, 33.33%, 50%, 66.66%, 90% and 95% shall inform the Company as well as the French Financial Market Authority (AMF) of the total
number of shares and voting rights and of securities giving access to the capital or voting rights that it owns immediately or over time within a period of
four trading days from the crossing of the said holding thresholds.

This obligation applies when crossing each of the above-mentioned thresholds in a downward direction.

In the event of failure to declare shares or voting rights exceeding the fraction that should have been declared, such shares shall be deprived of voting rights
at General Meetings of Shareholders for any meeting that would be held until the expiry of a period of two years from the date of regularization of the
notification in accordance with Article L. 233-14 of the French Commercial Code.

In addition, any shareholder, alone or acting in concert, crossing the 10%, 15%, 20% or 25% threshold shall file a declaration with the AMF pursuant to
which it shall expose its intention over the following 6 months, including notably whether it intends to continue acquiring shares of the Company, it intends
to acquire control over the Company, its intended strategy for the Company.

113

Further, and subject to certain exemptions, any shareholder crossing, alone or acting in concert, the 30% threshold shall file a mandatory public tender offer
with the AMF. Also, any shareholder holding directly or indirectly a number between 30% and 50% of the capital or voting rights and who, in less than 12
consecutive months, increases his/her/its holding of capital or voting rights by at least 1% company’s capital or voting rights, shall file a mandatory public
tender offer.

Differences in Corporate Law
The Company is a société anonyme, or S.A., incorporated under the laws of France. The laws applicable to French sociétés anonymes differ from laws
applicable  to  U.S.  corporations  and  their  shareholders.  Set  forth  below  is  a  summary  of  certain  differences  between  the  provisions  of  the  French
Commercial Code applicable to the Company and the Delaware General Corporation Law relating to shareholders’ rights and protections. This summary
is not intended to be a complete discussion of the respective rights and it is qualified in its entirety by reference to Delaware law and French law. .

Number of Directors

Director Qualifications

Removal of Directors

Under French law, a société anonyme must have at least three
and may have up to 18 directors. The number of directors is
fixed by or in the manner provided in the bylaws. Since
January 1, 2017, the number of directors of each gender may
not be less than 40%. Any appointment made in violation of
this limit that is not remedied will be null and void.

Under French law, a corporation may prescribe qualifications
for directors under its bylaws. In addition, under French law,
members of a board of directors of a corporation may be legal
entities (with the exception of the chairman of the board), and
such legal entities may designate an individual to represent
them and to act on their behalf at meetings of the board of
directors as well as the deliberations taken by the board
member irregularly appointed.

Under French law, directors may be removed from office,
with or without cause, at any shareholders’ meeting without
notice or justification, by a simple majority vote.

Under Delaware law, a corporation must have at
least one director and the number of directors
shall be fixed by or in the manner provided in
the bylaws.

Under Delaware law, a corporation may
prescribe qualifications for directors under its
certificate of incorporation or bylaws.

Under Delaware law, unless otherwise provided
in the certificate of incorporation, directors may
be removed from office, with or without cause,
by a majority stockholder vote, though in the
case of a corporation whose board is classified,
stockholders may effect such removal only for
cause.

Vacancies on the Board of Directors

Annual General Meeting

Under French law, vacancies on the board of directors
resulting from death or a resignation, provided that at least
three directors remain in office, may be filled by a majority of
the remaining directors pending ratification by the
shareholders by the next shareholders’ meeting.

Under Delaware law, vacancies on a
corporation’s board of directors, including those
caused by an increase in the number of
directors, may be filled by a majority of the
remaining directors.

Under French law, the annual general meeting of shareholders
shall be held at such place, on such date and at such time as
decided each year by the board of directors and notified to the
shareholders in the convening notice of the annual meeting,
within six months after the close of the relevant fiscal year
unless such period is extended by court order.

Under Delaware law, the annual meeting of
stockholders shall be held at such place, on such
date and at such time as may be designated from
time to time by the board of directors or as
provided in the certificate of incorporation or by
the bylaws.

stockholders must be given to each stockholder
entitled to vote at the meeting not less than 10
nor more than 60 days before the date of the
meeting and shall specify the place, date, hour,

statutory auditors, or by a court appointed agent (mandataire
ad hoc) or liquidator in certain circumstances, or by the
majority shareholder in capital or voting rights following a
public tender offer or exchange offer or the transfer of a
controlling block on the date decided by the board of directors

of Mandatory Statutory Notices (BALO) at least 35 days prior
to  a  meeting  and  made  available  on  the  website  of  the
company  at  least  21  days  prior  to  the  meeting.  Subject  to
limited  exceptions  provided  by  French 
law,  additional
convening notice is sent out at least 15 days prior to the date
of the meeting, by means of a notice inserted both in a legal
announcement bulletin of the registered office department and
in  the  French  Journal  of  Mandatory  Statutory  Notices
(BALO). Further, shareholders holding registered shares for at
least a month at the time latest insertions of the notices shall
be summoned individually, by regular letter (or by registered
letter  if  they  request  it  and  include  an  advance  of  expenses)

shareholders  may  also  be  transmitted  by  electronic  means  of
telecommunication,  in  lieu  of  any  such  mailing,  to  any
shareholder requesting it beforehand by registered letter with
acknowledgment  of  receipt  in  accordance  with  legal  and
regulatory requirements, specifying his e-mail address. When
the  shareholders’  meeting  cannot  deliberate  due  to  lack  of
required  quorum,  the  second  meeting  must  be  called  at  least
ten calendar days in advance in the same manner as used for
the first notice.

The convening notice shall specify the name of the company,
its  legal  form,  share  capital,  registered  office  address,
registration  number  with  the  French  Registry  of  Commerce
and  Companies,  the  place,  date,  hour  and  agenda  of  the

entered into a civil union or to another shareholder or to any
individual or legal entity of his choosing; or (iii) by sending a

meeting  or  for  successive  meetings  convened  with  the  same
agenda. It can also be granted for two meetings, one ordinary,
and the other extraordinary, held on the same day or within a
period of fifteen days.

Shareholder Action by Written Consent Under French law, shareholders’ action by written consent is

not permitted in a société anonyme.

Preemptive Rights

Under French law, in case of issuance of additional shares or
other  securities  for  cash  or  set-off  against  cash  debts,  the
existing  shareholders  have  preferential  subscription  rights  to
these  securities  on  a  pro  rata  basis  unless  such  rights  are
waived  by  a  two-thirds  majority  of  the  votes  cast  by  the
shareholders  present  at  the  extraordinary  general  meeting
deciding  or  authorizing  the  capital  increase,  voting  in  person
or represented by proxy or voting by mail. In case such rights
have  not  been  waived  by  the  extraordinary  general  meeting,
each  shareholder  may  individually  either  exercise,  assign  or
not  exercise  its  preferential  subscription  rights.  Preferential
subscription  rights  may  only  be  exercised  during 
the
subscription  period.  In  accordance  with  French  law,  the
exercise  period  shall  not  be  less  than  five  trading  days.
Preferential  subscription  rights  are  transferable  during  a
period  equivalent  to  the  subscription  period  but  starting  two
business days prior to the opening of the subscription period
and  ending  two  business  days  prior  to  the  closing  of  the
subscription period.

Sources of Dividends

Repurchase of Shares

FRANCE

DELAWARE

Under  French  law,  dividends  may  only  be  paid  by  a
French  société  anonyme  out  of  “distributable  profits,”  plus
any  distributable  reserves  and  “distributable  premium”  that
the  shareholders  decide  to  make  available  for  distribution,
other than those reserves that are specifically required by law.
  “Distributable  profits”  consist  of  the  unconsolidated  net
profits  of  the  relevant  corporation  for  each  fiscal  year,  as
increased  or  reduced  by  any  profit  or  loss  carried  forward
from prior years.
“Distributable premium” refers to the contribution paid by the
stockholders  in  addition  to  the  par  value  of  their  shares  for
their  subscription  that  the  stockholders  decide  to  make
available for distribution.
Except in case of a share capital reduction, no distribution can
be made to the stockholders when the net equity is, or would
become,  lower  than  the  amount  of  the  share  capital  plus  the
reserves  which  cannot  be  distributed  in  accordance  with  the
law or the bylaws.

Under Delaware law, dividends may be paid by
a Delaware corporation either out of (1) surplus
or (2) 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,
except  when  the  capital  is  diminished  by
depreciation  in  the  value  of  its  property,  or  by
losses, or otherwise, to an amount less than the
aggregate  amount  of  capital  represented  by
stock  having  a
issued  and  outstanding 
preference on the distribution of assets.

stock unless the capital of the corporation is
impaired or such redemption or repurchase
would impair the capital of the corporation.

Under French law, a corporation may acquire its own shares.
Such acquisition may be challenged on the ground of market
abuse  regulations.  However,  the  Market  Abuse  Regulation
596/2014  of  April  16,  2014  (MAR)  provides  for  safe  harbor
exemptions  when  the  acquisition  is  made  for  the  following
purposes:
• 
shareholders at the extraordinary general meeting;
• 
exchangeable into equity instruments; or
• 
 with  a  view  to  distributing  the  relevant  shares  to
employees  or  managers  under  a  profit-sharing,  free  share  or
share option plan.
All other purposes, and especially share buy-backs for
external growth operations by virtue of Article L. 20-10-62 of
the French Commercial Code, while not forbidden, must be
pursued in strict compliance of market manipulation and
insider dealing rules.
Under  the  Market  Abuse  Regulation  596/2014  of  April  16,
2014 (MAR) and in accordance with the General Regulations
of the French Financial Markets Authority, a corporation shall
report  to  the  competent  authority  of  the  trading  venue  on
which the shares have been admitted to trading or are traded,

behalf, more than 10% of its issues share capital.

Liability of Directors and Officers

Under French law, the bylaws may not include any provisions
limiting the liability of directors. Civil liability of the directors
may be sought for (1) an infringement of laws and regulations
applicable to the company, (2) breach of the bylaws and (3)
management failure.

 any breach of the director’s duty of loyalty

Under Delaware law, a corporation’s certificate
of incorporation may include a provision
eliminating or limiting the personal liability of a
director to the corporation and its stockholders
for damages arising from a breach of fiduciary
duty as a director. However, no provision can
limit the liability of a director for:
• 
to the corporation or its stockholders;
 acts or omissions not in good faith or that
• 
involve intentional misconduct or a knowing
violation of law;
• 
 intentional or negligent payment of unlawful
dividends or stock purchases or redemptions; or
redemptions; or any transaction from which the
director derives an improper personal benefit

Voting Rights

Shareholder Vote on Certain
Transactions

French law provides that, unless otherwise provided in the
bylaws, each shareholder is entitled to one vote for each share
of capital stock held by such shareholder. As from April 2016,
double voting rights are automatically granted to the shares
being registered since more than two years, unless the bylaws
are modified in order to provide otherwise.

Generally, under French law, completion of a merger,
dissolution, sale, lease or exchange of all or substantially all
of a corporation’s assets requires:
 the approval of the board of directors; and
• 
• 
 approval by a two-thirds majority of the votes cast by the
shareholders present, represented by proxy or voting by mail
at the relevant meeting or, in the case of a merger with a non-
EU company, approval of all shareholders of the corporation
(by exception, the extraordinary general meeting of the
acquiring company may delegate to the board authority to
decide a merger-absorption or to determine the terms and
conditions of the merger plan).

Delaware law provides that, unless otherwise
provided in the certificate of incorporation, each
stockholder is entitled to one vote for each share
of capital stock held by such stockholder.

Generally, under Delaware law, unless the
certificate of incorporation provides for the vote
of a larger portion of the stock, completion of a
merger, consolidation, sale, lease or exchange of
all or substantially all of a corporation’s assets
or dissolution requires:
 the approval of the board of directors; and
• 
• 
 approval by the vote of the holders of a
majority of the outstanding stock or, if the
certificate of incorporation provides for more or
less than one vote per share, a majority of the
votes of the outstanding stock of a corporation
entitled to vote on the matter.

Dissent or Dissenters’ Appraisal Rights

French law does not provide for any such right but provides
that a merger is subject to shareholders’ approval by a two-
thirds majority vote as stated above.

Under Delaware law, a holder of shares of any
class or series has the right, in specified
circumstances, to dissent from a merger or
consolidation by demanding payment in cash
for the stockholder’s shares equal to the fair
value of those shares, as determined by the
Delaware Chancery Court in an action timely
brought by the corporation or a dissenting
stockholder. Delaware law grants these
appraisal rights only in the case of mergers or
consolidations and not in the case of a sale or
transfer of assets or a purchase of assets for
stock. Further, no appraisal rights are available
for shares of any class or series that is listed on
a national securities exchange or held of record
by more than 2,000 stockholders, unless the
agreement of merger or consolidation requires
the holders to accept for their shares anything
other than:
• 
•

exchange or held of record by more than 2,000
stockholders;
• 
 cash in lieu of fractional shares of the stock
described in the two preceding bullet points; or

holders of shares of the surviving corporation in
specified mergers that do not require the vote of

Standard of Conduct for Directors

French law does not contain specific provisions setting forth
the standard of conduct of a director. However, directors have
a duty to act without self-interest, on a well-informed basis
and they cannot make any decision against a corporation’s
corporate interest (intérêt social). In addition, directors shall
take into account social and environmental issues arising out
of the company’s activity.

Delaware law does not contain specific
provisions setting forth the standard of conduct
of a director. The scope of the fiduciary duties
of directors is generally determined by the
courts of the State of Delaware. In general,
directors have a duty to act without self-interest,
on a well-informed basis and in a manner they
reasonably believe to be in the best interest of
the stockholders.

Shareholder Suits

French law provides that a shareholder, or a group of
shareholders, may initiate a legal action to seek
indemnification from the directors of a corporation in the
corporation’s interest if it fails to bring such legal action itself.
If so, any damages awarded by the court are paid to the
corporation and any legal fees relating to such action may be
borne by the relevant shareholder or the group of
shareholders.
The plaintiff must remain a shareholder through the duration
of the legal action. There is no other case where shareholders
may initiate a derivative action to enforce a right of a
corporation. A shareholder may alternatively or cumulatively
bring individual legal action against the directors, provided he
has suffered distinct damages from those suffered by the
corporation. In this case, any damages awarded by the court
are paid to the relevant shareholder.

Under Delaware law, a stockholder may initiate
a derivative action to enforce a right of a
corporation if the corporation fails to enforce
the right itself. The complaint must:
• 
 state that the plaintiff was a stockholder at
the time of the transaction of which the plaintiff
complains or that the plaintiff’s shares thereafter
devolved on the plaintiff by operation of law;
and
• 
the plaintiff to obtain the action the plaintiff
desires from the directors and the reasons for
the plaintiff’s failure to obtain the action; or
• 
Additionally, the plaintiff must remain a
stockholder through the duration of the
derivative suit. The action will not be dismissed
or compromised without the approval of the
Delaware Court of Chancery.

Amendment of Bylaws

Under French law, only the extraordinary shareholders’
meeting is authorized to adopt or amend the bylaws.
However, the board of directors is authorized to (i) modify the
bylaws as a result of a decision to move the company’s
registered office and (ii) to bring to the bylaws any
modification rendered necessary by an amendment to an
applicable law or regulation if the board of directors has been
prior authorized by the extraordinary shareholders meeting for
this purpose, and subject, in both cases, to ratification by the
next extraordinary shareholders’ meeting.

Under Delaware law, the stockholders entitled
to vote have the power to adopt, amend or
repeal the bylaws of the corporation. A
corporation may also confer, in its certificate of
incorporation, that power upon the board of
directors.

Changes in Share Capital

Increases  in  Share  Capital  (Article  10  of  the  Bylaws).  Pursuant  to  French  law,  the  Company’s  share  capital  may  be  increased  only  with  shareholders’
approval  at  an  extraordinary  general  shareholders’  meeting  following  the  recommendation  of  the  Company’s  board  of  directors.  The  shareholders  may
delegate to the Company’s board of directors either the authority (délégation de compétence) or the power (délégation de pouvoir) to carry out any increase
in share capital.

Increases in the Company’s share capital may be effected by:

• issuing additional shares;

• increasing the par value of existing shares;

• creating a new class of equity securities; and

• exercising the rights attached to securities giving access to the share capital.

Increases in share capital by issuing additional securities may be effected through one or a combination of the following:

• in consideration for cash;

• in consideration for assets contributed in kind;

• through an exchange offer;

• by conversion of previously issued debt instruments;

120

• by capitalization of profits, reserves or share premium; and

• subject to certain conditions, by way of offset against debt incurred by the Company.

Decisions  to  increase  the  share  capital  through  the  capitalization  of  reserves,  profits  and/or  share  premium  require  shareholders’  approval  at  an
extraordinary general shareholders’ meeting, acting under the quorum and majority requirements applicable to ordinary shareholders’ meetings. Increases
effected by an increase in the par value of shares require unanimous approval of the shareholders, unless effected by capitalization of reserves, profits or
share  premium.  All  other  capital  increases  require  shareholders’  approval  at  an  extraordinary  general  shareholders’  meeting  acting  under  the  regular
quorum and majority requirements for such meetings.

Reduction in Share Capital.  Pursuant  to  French  law,  any  reduction  in  the  Company’s  share  capital  requires  shareholders’  approval  at  an  extraordinary
general shareholders’ meeting following the recommendation of the Company’s board of directors. The share capital may be reduced either by decreasing
the  par  value  of  the  outstanding  shares  or  by  reducing  the  number  of  outstanding  shares.  The  number  of  outstanding  shares  may  be  reduced  by  the
repurchase and cancellation of shares. Holders of each class of shares must be treated equally unless each affected shareholder agrees otherwise.

Preferential Subscription Right. According to French law, if the Company issues additional securities for cash, current shareholders will have preferential
subscription rights to these securities on a pro rata basis. Preferential subscription rights entitle the individual or entity that holds them to subscribe pro
rata based on the number of shares held by them to the issuance of any securities increasing, or that may result in an increase of, the Company’s share
capital by means of a cash payment or a set-off of cash debts. The preferential subscription rights are transferable during the subscription period relating to
a particular offering.

Pursuant to recent legislation that went into effect on October 1, 2016, the preferential subscription rights will be transferable during a period starting two
days prior to the opening of the subscription period and ending two days prior to the closing of the subscription period.

The preferential subscription rights with respect to any particular offering may be waived at an extraordinary general meeting by a two-thirds vote of the
Company’s shareholders or individually by each shareholder. The Company’s board of directors and its independent auditors are required by French law to
present reports to the shareholders’ meeting that specifically address any proposal to waive the preferential subscription rights.

In  the  future,  to  the  extent  permitted  under  French  law,  the  Company  may  seek  shareholder  approval  to  waive  preferential  subscription  rights  at  an
extraordinary  general  shareholders’  meeting  in  order  to  authorize  the  board  of  directors  to  issue  additional  shares  and/or  other  securities  convertible  or
exchangeable into shares.

Listing

Our ADSs are listed on the Nasdaq Global Select Market under the symbol “ERYP.” Our ordinary shares are listed on Euronext Paris under the symbol
“ERYP.”

Transfer Agent and Registrar

The  transfer  agent  and  registrar  for  our  ADSs  is  The  Bank  of  New  York  Mellon.  Our  share  register  for  our  ordinary  shares  is  maintained  by  Société
Générale. The share register reflects only record owners of our ordinary shares. Holders of our ADSs are not treated as our shareholders and their names
are therefore not entered in our share register. The depositary, the custodian or their nominees are the holder of the shares underlying our ADSs. Holders of
our  ADSs  have  a  right  to  receive  the  ordinary  shares  underlying  their  ADSs.  For  discussion  on  our  ADSs  and  ADS  holder  rights,  see  “Description  of
American Depositary Shares” in this prospectus.

LIMITATIONS AFFECTING SHAREHOLDERS OF A FRENCH COMPANY

Ownership of ADSs or Shares by Non-French Residents
Neither the French Commercial Code nor our bylaws presently impose any restrictions on the right of non-French residents or non-French shareholders to
own and vote shares. However, non-French residents must file a declaration for statistical purposes with the Bank of France (Banque de France)  within
twenty  working  days  following  the  date  of  certain  direct  foreign  investments  in  us,  including  any  purchase  of  our  ADSs.  In  particular  such  filings  are
required in connection with investments exceeding €15,000,000 that lead to the acquisition of at least 10% of the share capital or voting rights or cross such
10%  threshold.  Violation  of  this  filing  requirement  may  be  sanctioned  by  five  years’  imprisonment  and  a  fine  up  to  twice  the  amount  of  the  relevant
investment.  This  amount  may  be  increased  fivefold  if  the  violation  is  made  by  a  legal  entity.  Moreover,  certain  foreign  investments  in  companies
incorporated under French laws are subject to the prior authorization from the French Minister of the Economy, where all or part of the target’s business
and activity relate to a strategic sector, such as energy, transportation, public health, telecommunications, etc.,

121

Foreign Exchange Controls

Under  current  French  foreign  exchange  control  regulations  there  are  no  limitations  on  the  amount  of  cash  payments  that  we  may  remit  to  residents  of
foreign  countries.  Laws  and  regulations  concerning  foreign  exchange  controls  do,  however,  require  that  all  payments  or  transfers  of  funds  made  by  a
French  resident  to  a  non-resident  such  as  dividend  payments  be  handled  by  an  accredited  intermediary.  All  registered  banks  and  substantially  all  credit
institutions in France are accredited intermediaries.

Availability of Preferential Subscription Rights

Our shareholders will have the preferential subscription rights described under “Description of Share Capital—Key Provisions of Our Bylaws and French
Law Affecting Our Ordinary Shares—Changes in Share Capital—Preferential Subscription Right.” Under French law, shareholders have preferential rights
to subscribe for cash issues of new shares or other securities giving rights to acquire additional shares on a pro rata basis. Holders of our securities in the
United  States  (which  may  be  represented  by  ADSs)  will  not  be  able  to  exercise  preferential  subscription  rights  for  their  securities  unless  a  registration
statement under the Securities Act is effective with respect to such rights or an exemption from the registration requirements imposed by the Securities Act
is available. We may, from time to time, issue new shares or other securities giving rights to acquire additional shares (such as warrants) at a time when no
registration statement is in effect and no Securities Act exemption is available. If so, holders of our securities in the United States will be unable to exercise
any preferential subscription rights and their interests will be diluted. We are under no obligation to file any registration statement in connection with any
issuance  of  new  shares  or  other  securities.  We  intend  to  evaluate  at  the  time  of  any  rights  offering  the  costs  and  potential  liabilities  associated  with
registering  the  rights,  as  well  as  the  indirect  benefits  to  us  of  enabling  the  exercise  by  holders  of  shares  in  the  United  States  and  ADS  holders  of  the
subscription rights, and any other factors we consider appropriate at the time, and then to make a decision as to whether to register the rights. We cannot
assure you that we will file a registration statement.

For  holders  of  our  ordinary  shares  represented  by  ADSs,  the  depositary  may  make  these  rights  or  other  distributions  available  to  ADS  holders.  If  the
depositary does not make the rights available to ADS holders and determines that it is impractical to sell the rights, it may allow these rights to lapse. In
that case, ADS holders will receive no value for them. The section of this prospectus titled “Description of American Depositary Shares—Dividends and
Other Distributions” explains in detail the depositary’s responsibility in connection with a rights offering. See also “Risk Factors—The right as a holder of
ADSs to participate in any future preferential subscription rights or to elect to receive dividends in shares may be limited, which may cause dilution to the
holders of our ADSs”.

OCABSA Agreement with Alpha Blue Ocean

We  entered  into  an  agreement  on  June  24,  2020  (the  "OCABSA  Agreement")  allowing  the  issuance  for  the  benefit  of  the  Luxembourg-based  fund

exercised, as described in the table above.

Accordingly, we may decide to issue additional tranches up to a maximum of €6 million until June 2022, subject to the limit of 20% dilution, representing
€3.0 million as of the date of this Annual Report based on a share price of €1.28 (closing share price on the day before the date of this Annual Report). It is
specified that this maximum amount is not guaranteed and depends on a number of factors and conditions beyond our control.

At-the-Market (ATM) Program

On September 21, 2020, we entered into a sales agreement with Cowen and Company, LLC (“Cowen”) pursuant to which we may issue and sell, from time
to time at our sole discretion, ordinary shares in the form of ADSs to eligible investors at market prices, with aggregate gross sales proceeds of up to $30
million,  subject  to  the  regulatory  limit  of  20%  dilution  (this  threshold  is  calculated  based  on  the  total  number  of  shares  listed  on  Euronext  without
prospectus during the twelve months before the issuance).

We  agreed  to  pay  Cowen  commission  equal  to  3.0%  of  the  gross  proceeds  of  the  sales  price  of  all  ADSs  sold  through  it  as  sales  agent  under  the  sales
agreement. The offering of our ADSs pursuant to the sales agreement will terminate on the earliest of (1) the sale of all of the ordinary shares subject to the
sales agreement, or (2) termination of the sales agreement by us or the agent. We and the agent may terminate the sales agreement at any time in our sole
discretion upon ten (10) days’ prior notice. The agent may terminate the sales agreement at any time in certain circumstances, including the occurrence of a
material adverse change that, in the sales agent’s judgment, may materially impair the ability of the agent to sell the shares thereunder or a suspension or
limitation of trading of our ADSs on Nasdaq.

In February 2021, we sold shares under this ATM program resulting in gross proceeds of $8.0 million, or €6.6 million, and net proceeds of $7.8 million, or
€6.4 million.

Registered Direct Offerings

On April 29, 2021, we entered into subscription agreements with certain institutional and accredited investors providing for the issuance of an aggregate of
1,034,483 units (the “Units”), each Unit consisting of four ADSs, each representing one ordinary share, €0.10 nominal value per share, and three warrants,
each to purchase one ordinary share, in a registered direct offering (the “April 2021 Offering”) at $29.00 per Unit for aggregate gross proceeds to us of
approximately  $30.0  million.  Under  the  subscription  agreements,  the  investors  received  warrants  to  purchase  an  aggregate  of  up  to  3,103,449  ordinary
shares representing 12,95% of the Company's share capital on a fully diluted basis prior to the offer. Such warrants became immediately exercisable and
will expire two years from the date of issuance (i.e. May 4, 2023), subject to any extension of such exercise period as set forth therein. The warrants have
an exercise price of €7.50 per share, subject to adjustment as set forth therein. The issuance of the 4,137,932 new shares underlying the ADSs resulted in an
immediate capital increase of €24,868,971.30, representing approximately 19.12% of the Company's share capital and voting rights prior to the offering.

In connection with the offering, we also entered into a placement agency agreement with H.C. Wainwright & Co., LLC (“HCW”), pursuant to which HCW
agreed to serve as the exclusive placement agent for us in connection with the registered direct offering. We agreed to pay HCW a placement agent fee
equal to 7% of the gross proceeds from the sale of the Units in the offering, a non-accountable expense allowance of $50,000, an accountable expense
allowance of $100,000 and clearing fees of $15,950.

On December 14, 2021, we entered into a subscription agreement with Armistice Capital Master Fund Ltd. (“Armistice”), providing for the issuance of an
aggregate  of  769,608  Units  in  a  registered  direct  offering  (the  “December  2021  Offering”)  at  $10.20  per  Unit  for  aggregate  gross  proceeds  to  us  of
approximately $7.85 million. Under this subscription agreement, Armistice received a warrant to purchase an aggregate of up to 2,308,824 ordinary shares
representing 6,8% of the Company's share capital on a fully diluted basis prior to the offer. Such warrant became immediately exercisable and will expire
two years from the date of issuance (i.e. December 20, 2023), subject to any extension of such exercise period as set forth therein. The warrants have an
exercise  price  of  €2.83  per  share,  subject  to  adjustment  as  set  forth  therein.  The  issuance  of  the  3,078,432  new  ordinary  shares  underlying  the  ADSs
resulted in an immediate capital increase of €6,957,256.32, representing approximately 11.02% of the share capital and voting rights of the Company prior
to the offering. We also entered into a placement agency agreement with HCW on substantially similar terms as the April 2021 agreement.

For  additional  information  on  our  material  contracts,  please  see  “Item  4.  Information  on  the  Company,”  “Item  6.  Directors,  Senior  Management  and
Employees,” and “Item 7.B. Related Party Transactions” of this Annual Report on 20-F.

10.D.

Exchange Controls.

Under  current  French  foreign  exchange  control  regulations  there  are  no  limitations  on  the  amount  of  cash  payments  that  we  may  remit  to  residents  of
foreign  countries.  Laws  and  regulations  concerning  foreign  exchange  controls  do,  however,  require  that  all  payments  or  transfers  of  funds  made  by  a
French  resident  to  a  non-resident  such  as  dividend  payments  be  handled  by  an  accredited  intermediary.  All  registered  banks  and  substantially  all  credit
institutions in France are accredited intermediaries.

10.E.

Taxation.

The following describes certain material U.S. federal income tax and French tax considerations relating to the acquisition, ownership and disposition of our
ADSs by a U.S. holder (as defined below). This summary does not address all U.S. federal income tax and French tax matters that may be relevant to a
particular  U.S.  holder.  This  summary  does  not  address  tax  considerations  applicable  to  a  holder  of  our  ADSs  that  may  be  subject  to  special  tax  rules
including, without limitation, the following:

•

•

•

•

•

•

•

banks, financial institutions or insurance companies;

brokers,  dealers  or  traders  in  securities,  currencies,  commodities  or  notional  principal  contracts,  including  those  that  use  the  mark-to-market
method of tax accounting;

tax-exempt entities or organizations, including an “individual retirement account” or “Roth IRA” as defined in Section 408 or 408A of the Code
(as defined below), respectively, and private foundations;

governmental or international organizations;

real estate investment trusts, regulated investment companies or grantor trusts;

persons that hold their ADSs as part of a “hedging,” “integrated,” “wash sale” or “conversion” transaction or as a position in a “straddle” for U.S.
federal income tax purposes;

S corporations, partnerships or other entities or arrangements treated as partnerships for U.S. federal income tax purposes (and investors therein);

126

•

•

•

•

•

•

•

certain former citizens or long-term residents of the United States;

persons that received their ADSs pursuant to the exercise of any employee stock options or otherwise as compensation for the performance of
services;

persons that acquired their ADSs in connection with a trade or business, permanent establishment or fixed place of business outside of the United
States, including a permanent establishment in France;

pension plans;

cooperatives;

holders that own directly, indirectly or constructively 5% or more of our stock (by vote or value); and

holders that have a “functional currency” other than the U.S. dollar.

If  a  partnership  (or  any  other  entity  treated  as  a  partnership  for  U.S.  federal  income  tax  purposes)  holds  our  ADSs,  the  U.S.  federal  income  tax
consequences relating to an investment in the ADSs will depend in part upon the status of the partner in the partnership and the activities of the partnership.
U.S.  holders  that  are  such  partners  or  partnerships  should  consult  their  tax  advisors  regarding  the  U.S.  federal  income  tax  considerations  of  acquiring,
owning and disposing of our ADSs in their particular circumstances.

For purposes of this discussion, a “U.S. holder” is a beneficial owner of our ADSs that is (or is treated as), for U.S. federal income tax purposes:

•

•

•

•

an individual who is a citizen or resident of the United States;

a corporation, or other entity treated as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United
States, any state therein or the District of Columbia;

an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

a trust, if a court within the United States is able to exercise primary supervision over its administration and one or more U.S. persons have the
authority  to  control  all  of  the  substantial  decisions  of  such  trust,  or  if  such  trust  has  a  valid  election  in  effect  under  applicable  U.S.  Treasury
Regulations to be treated as a U.S. person.

This discussion is based in part upon the representations of the depositary and the assumption that each obligation in the amended and restated deposit
agreement  and  any  related  agreement  will  be  performed  in  accordance  with  its  terms.  Furthermore,  a  holder  of  an  ADS  generally  should  be  treated  as
holding  the  underlying  share  represented  by  the  ADS.  As  such,  no  gain  or  loss  generally  will  be  recognized  upon  an  exchange  of  the  ADS  for  the
underlying share.

Persons considering an investment in our ADSs should consult their tax advisors as to the particular tax consequences applicable to them relating
to the acquisition, ownership and disposition of the ADSs, including the applicability of U.S. federal, state and local tax laws, French tax laws and
other non-U.S. tax laws.

Material French Tax Considerations

The  following  describes  the  material  French  income  tax  consequences  to  U.S.  holders  of  purchasing,  owning  and  disposing  of  our  ADSs  and,  unless
otherwise noted, this discussion is the opinion of Gide Loyrette Nouel A.A.R.P.I, our French tax counsel, insofar as it relates to matters of French tax law
and legal conclusions with respect to those matters.

This discussion does not purport to be a complete analysis or listing of all potential tax effects of the acquisition, ownership or disposition of our ADSs to
any particular investor, and does not discuss tax considerations that arise from rules of general application or that are generally assumed to be known by
investors. All of the following is subject to change. Such changes could apply retroactively and could affect the consequences described below.

The description of the French income tax and wealth tax consequences set forth below is based on the Convention Between the Government of the United
States of America and the Government of the French Republic for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to
Taxes on Income and Capital of August 31, 1994, or the Treaty, which came into force on December 30, 1995 (as amended by any subsequent protocols,
including the protocol of January 13, 2009), and the tax guidelines issued by the French tax authorities in force as of the date of this Annual Report.

This discussion applies only to investors that are entitled to Treaty benefits under the “Limitation on Benefits” provision contained in the Treaty.

France has introduced a comprehensive set of new tax rules applicable to French assets that are held by or in foreign trusts. These rules provide inter alia
for the inclusion of trust assets in the settlor’s net assets for the purpose of applying the French real estate wealth tax, for the application of French gift and
death duties to French assets held in trust, for a specific tax on capital on the French assets of foreign trusts not already subject to the French real estate
wealth tax and for a number of French tax reporting and disclosure obligations. The following discussion does not address the French tax consequences
applicable to securities (including ADSs) held in trusts. If ADSs are held in trust, the grantor, trustee and beneficiary are urged to consult their own tax
advisor regarding the specific tax consequences of acquiring, owning and disposing of securities (including ADSs).

U.S. holders are urged to consult their own tax advisors regarding the tax consequences of the purchase, ownership and disposition of securities in light of
their particular circumstances, especially with regard to the “Limitations on Benefits” provision.

Estate and Gift Taxes and Transfer Taxes

In  general,  a  transfer  of  securities  by  gift  or  by  reason  of  death  of  a  U.S.  holder  that  would  otherwise  be  subject  to  French  gift  or  inheritance  tax,
respectively,  will  not  be  subject  to  such  French  tax  by  reason  of  the  Convention  between  the  Government  of  the  United  States  of  America  and  the
Government  of  the  French  Republic  for  the  Avoidance  of  Double  Taxation  and  the  Prevention  of  Fiscal  Evasion  with  Respect  to  Taxes  on  Estates,
Inheritances and Gifts, dated November 24, 1978 (as amended by the protocol of December 8, 2004), unless (i) the donor or the transferor is domiciled in
France at the time of making the gift or at the time of his or her death, or (ii) the securities were used in, or held for use in, the conduct of a business
through a permanent establishment or a fixed base in France.

Pursuant to Article 235 ter ZD of the Code général des impôts (French Tax Code, or FTC), purchases of shares or ADSs of a French company listed on a
regulated market of the European Union or on a foreign regulated market formally acknowledged by the French Financial Market Authority (AMF) are
subject to a 0.3% French tax on financial transactions provided that the issuer’s market capitalization exceeds 1 billion euros as of December 1 of the year
preceding the taxation year pursuant to Regulations BOI-ANNEX-000467-29/12/2021 issued on December 29, 2021. The Nasdaq Global Select Market is
not currently acknowledged by the French AMF but this may change in the future. A list of French relevant companies whose market capitalization exceeds
1  billion  euros  as  of  December  1  of  the  year  preceding  the  taxation  year  is  published  annually  and  at  least  once  a  year,  by  the  French  State.  As  at
December 1, 2021, our market capitalization did not exceed 1 billion euros.

Following the global offering, purchases of our securities may be subject to such tax provided that its market capitalization exceeds 1 billion euros and that
the Nasdaq Global Select Market is acknowledged by the French AMF.

In  the  case  where  Article  235  ter  ZD  of  the  FTC  is  not  applicable,  transfers  of  shares  issued  by  a  French  company,  which  is  listed  on  a  regulated  or
organized market within the meaning of the French Financial and Monetary Code, are subject to uncapped registration duties at the rate of 0.1% if the
transfer  is  evidenced  by  a  written  statement  (“acte”)  executed  either  in  France  or  outside  France.  Although  there  is  no  case  law  or  official  guidelines
published by the French tax authorities on this point, transfers of ADSs should remain outside of the scope of the aforementioned 0.1% registration duties.

Tax on Sale or Other Disposition

As  a  matter  of  principle,  under  French  tax  law,  a  U.S.  holder  should  not  be  subject  to  any  French  tax  on  any  capital  gain  from  the  sale,  exchange,
repurchase or redemption by us of ordinary shares or ADSs, provided such U.S. holder is not a French tax resident for French tax purposes and has not held
more than 25% of our dividend rights, known as “droits aux benefices sociaux,” at any time during the preceding five years, either directly or indirectly,
and,  as  relates  to  individuals,  alone  or  with  relatives  (as  an  exception,  a  U.S  holder  resident,  established  or  incorporated  in  a  non-cooperative  State  or
territory as defined in Article 238-0 A of the FTC should be subject to a 75% withholding tax in France on any such capital gain, regardless of the fraction
of the dividend rights it holds). The list of non-cooperative State or territories is published by decree and is in principal updated annually. This list was last
updated on 26 February 2021, and currently includes American Samoa, Anguilla, the British Virgin Islands, Dominica, Fiji, Guam, Palaos, Panama, Samoa,
Seychelles, Trinidad and Tobago, the United States Virgin Islands and Vanuatu. States referred to in Article 238-0 A 2 bis 2° of the FTC, and thus outside
of the scope of Article 125 A III of the FTC, are currently American Samoa, Dominica, Fiji, Guam, Palaos, Samoa, Trinidad and Tobago and the United
States Virgin Islands.

Under application of the Treaty, a U.S. holder who is a U.S. resident for purposes of the Treaty and entitled to Treaty benefit will not be subject to French
tax on any such capital gain unless the ordinary shares or the ADSs form part of the business property of a permanent establishment or fixed base that the
U.S. holder has in France. U.S. holders who own ordinary shares or ADSs through U.S. partnerships that are not resident for Treaty purposes are advised to
consult their own tax advisors regarding their French tax treatment and their eligibility for Treaty benefits in light of their own particular circumstances. A
U.S. holder that is not a U.S. resident for Treaty purposes or is not entitled to Treaty benefit (and in both cases is not resident, established or incorporated in
a non-cooperative State or territory as defined in Article 238-0 A of the FTC) and has held more than 25% of our dividend rights, known as “droits aux

128

benefices sociaux,” at any time during the preceding five years, either directly or indirectly, and, as relates to individuals, alone or with relatives will be
subject to a levy in France at the rate of 12.8% if such U.S. holder is an individual or 25% for corporate bodies or other legal entities. Special rules apply to
U.S. holders who are residents of more than one country.

Taxation of Dividends

Dividends paid by a French corporation to non-residents of France are generally subject to French withholding tax at a rate of 12.8% when the recipient is
an individual and 25% otherwise. Dividends paid by a French corporation in a non-cooperative State or territory, as defined in Article 238-0 A of the FTC,
will  generally  be  subject  to  French  withholding  tax  at  a  rate  of  75%.  However,  eligible  U.S.  holders,  other  than  individuals  subject  to  the  French
withholding tax at a rate of 12.8%, entitled to Treaty benefits under the ‘‘Limitation on Benefits’’ provision contained in the Treaty who are U.S. residents,
as defined pursuant to the provisions of the Treaty, will not be subject to this 25% or 75% withholding tax rate, but may be subject to the withholding tax at
a reduced rate (as described below).

Under  the  Treaty,  the  rate  of  French  withholding  tax  on  dividends  paid  to  an  eligible  U.S.  holder  who  is  a  U.S.  resident  as  defined  pursuant  to  the
provisions of the Treaty and whose ownership of the ordinary shares or ADSs is not effectively connected with a permanent establishment or fixed base
that such U.S. holder has in France, may be reduced to 15%, or to 5% if such U.S. holder is a corporation and owns directly or indirectly at least 10% of the
share capital of the issuer; such U.S. holder may claim a refund from the French tax authorities of the amount withheld in excess of the Treaty rates of 15%
or 5%, if any.

For U.S. holders that are not individuals but are U.S. residents, as defined pursuant to the provisions of the Treaty, the requirements for eligibility for Treaty
benefits,  including  the  reduced  5%  or  15%  withholding  tax  rates  contained  in  the  ‘‘Limitation  on  Benefits’’  provision  of  the  Treaty,  are  complex,  and
certain technical changes were made to these requirements by the protocol of January 13, 2009. U.S. holders are advised to consult their own tax advisors
regarding their eligibility for Treaty benefits in light of their own particular circumstances. Dividends paid to an eligible U.S. holder may immediately be
subject to the reduced rates of 5% or 15% provided that:

◦

◦

such holder establishes before the date of payment that it is a U.S. resident under the Treaty by completing and providing the depositary with a
treaty form (Form 5000) in accordance with the French guidelines (BOI-INT-DG-20-20-20-20-12/09/2012); or

the depositary or other financial institution managing the securities account in the U.S. of such holder provides the French paying agent with a
document  listing  certain  information  about  the  U.S.  holder  and  its  ordinary  shares  or  ADSs  and  a  certificate  whereby  the  financial  institution
managing  the  U.S.  holder’s  securities  account  in  the  United  States  takes  full  responsibility  for  the  accuracy  of  the  information  provided  in  the
document.

Otherwise,  dividends  paid  to  a  U.S.  holder,  other  than  individuals  subject  to  the  French  withholding  tax  at  a  rate  of  12.8%,  will  be  subject  to  French
withholding tax at the rate of 25%, or 75% if paid in a non-cooperative State or territory (as defined in Article 238-0 A of the FTC), and then reduced at a
later date to 5% or 15%, provided that such holder duly completes and provides the French tax authorities with the treaty forms Form 5000 and Form 5001
before December 31 of the second calendar year following the year during which the dividend is paid.

Certain qualifying pension funds and certain other tax-exempt entities are subject to the same general filing requirements as other U.S. holders except that
they may have to supply additional documentation evidencing their entitlement to these benefits.

Form 5000 and Form 5001, together with instructions, will be provided by the depositary to all U.S. holders registered with the depositary. The depositary
will arrange for the filing with the French tax authorities of all such forms properly completed and executed by U.S. holders of ordinary shares or ADSs
and returned to the depositary in sufficient time so that they may be filed with the French tax authorities before the distribution in order to immediately
obtain  a  reduced  withholding  tax  rate.  Otherwise,  the  depositary  must  withhold  tax  at  the  full  rate  of  25%  or  75%  as  applicable.  In  that  case,  the  U.S.
holders may claim a refund from the French tax authorities of the excess withholding tax.

Since the withholding tax rate applicable under French domestic law to U.S. holders who are individuals does not exceed the cap provided in the Treaty
(i.e. 15%), the 12.8% rate shall apply, without any reduction provided under the Treaty.

Besides,  please  note  that  pursuant  to  Article  235  quater  of  the  FTC  and  under  certain  conditions  (in  particular  reporting  obligations),  a  corporate  U.S.
Holder  which  is  in  a  tax  loss  position  for  the  fiscal  year  during  which  the  dividend  is  received  may  be  entitled  to  a  deferral  regime,  and  obtain  a
withholding tax refund. The tax deferral ends in respect of the first financial year during which this U.S. Holder is in a profit making position, as well as in
the cases set out in Article 235 quater of the FTC. Also, pursuant to newly introduced Article 235 quinquies of the FTC and under certain conditions, a
corporate U.S. Holder may be entitled to a refund of a fraction of the withholding tax, up to the difference between the withholding tax paid (on a gross
basis) and the withholding tax based

129

on the dividend net of the expenses incurred for the acquisition and conservation directly related to the income, provided (i) that these expenses would have
been tax deductible had the U.S. Holder been established in France, and (ii) that the tax rules in the United States do not allow the U.S. Holder to offset the
withholding tax.

Real Estate Wealth Tax

On January 1, 2018, the French wealth tax was replaced with a real estate wealth tax (impôt sur la fortune immobilière, or IFI). Individuals holding directly
or indirectly through one or more legal entities real estate assets or rights with a value exceeding €1,300,000 may fall within the scope of the IFI. A general
exclusion applies to real estate assets owned by companies carrying out a commercial or industrial activity when the taxpayer (together with the members
of his/her household) holds directly or indirectly less than 10% of the share capital or voting rights of the company. ADSs owned by a U.S. holder should
not fall within the scope of the IFI provided that such U.S. holder does not own (together with the members of his/her household) directly or indirectly a
shareholding  exceeding  10%  of  the  financial  rights  and  voting  rights  of  our  share  capital.  U.S.  holders  holding  directly  or  indirectly  a  shareholding
exceeding 10% of the financial rights and voting rights of our share capital should seek additional advice.

Material U.S. Federal Income Tax Considerations

This section discusses certain material U.S. federal income tax considerations relating to the acquisition, ownership and disposition of our ADSs by a U.S.
holder that holds the ADSs as a "capital asset" for U.S. federal income tax purposes (generally, property held for investment). This discussion does not
address estate, gift, or alternative minimum tax considerations, the Medicare net investment tax, the special tax accounting rules under Section 451(b) of
the Code or any state, local or non-U.S. tax considerations of the acquisition, ownership and disposition of our ADSs.

This discussion is based on the U.S. Internal Revenue Code of 1986, as amended, or the Code, existing, proposed and temporary U.S. Treasury Regulations
promulgated thereunder and administrative and judicial interpretations thereof, in each case as in effect and available on the date hereof. All the foregoing
is  subject  to  change,  which  change  could  apply  retroactively,  and  to  differing  interpretations,  all  of  which  could  affect  the  tax  considerations  described
herein.  There  can  be  no  assurances  that  the  U.S.  Internal  Revenue  Service,  or  the  IRS,  will  not  take  a  position  different  from  what  is  described  herein
concerning the tax consequences of the acquisition, ownership and disposition of our ADSs or that such a position would not be sustained by a court. U.S.
holders should consult their tax advisers concerning the U.S. federal, state, local and non-U.S. tax consequences of acquiring, owning and disposing of our
ADSs in their particular circumstances.

Passive Foreign Investment Company Considerations. Generally, if, for any taxable year, at least 75% of our gross income is passive income, or at least
50% of the value of our assets is attributable to assets that produce passive income or are held for the production of passive income, including cash, we will
be  characterized  as  a  passive  foreign  investment  company,  or  PFIC,  for  U.S.  federal  income  tax  purposes.  For  purposes  of  these  tests,  passive  income
includes dividends, allocations of income with respect to any partnership, interest, and gains from the sale or exchange of investment property and rents and
royalties other than rents and royalties which are received from unrelated parties in connection with the active conduct of a trade or business. Furthermore,
a non-U.S. corporation that directly or indirectly owns at least 25% by value of the stock of another corporation is treated as directly holding and receiving
its proportionate share of assets and income, respectively, of such other corporation.

The annual determination of whether we are a PFIC for a taxable year is fact-intensive and made after the close of such taxable year applying principles
and methodologies that in some circumstances are unclear and subject to varying interpretations. For instance, whether we are a PFIC will depend on the
composition of our income (including whether we will receive certain non-refundable grants or subsidies and whether such amounts and reimbursements of
certain  refundable  research  tax  credits  will  constitute  gross  income  for  purposes  of  the  PFIC  rules).  Whether  we  are  a  PFIC  also  will  depend  on  the
composition and value of our assets, including goodwill, which may be determined in large part by reference to the market value of our ADSs from time to
time, which may fluctuate considerably. If our market capitalization declines while we hold a substantial amount of cash and cash-equivalents, which may
depend on how quickly we utilize our cash proceeds from our global offerings in our business, we may be more likely to be characterized as a PFIC. Based
on the composition of our gross income, assets, activities and market capitalization and the nature of our business, and due to fluctuations in our stock
price, we believe that we may have been characterized as a PFIC for our taxable year ending December 31, 2021. However, because our PFIC status is
subject to a number of uncertainties and it is very early in the year, we cannot provide any assurances, and our U.S. counsel expresses no opinion, with
respect to our PFIC status for any taxable year.

If we are classified as a PFIC in any taxable year during which a U.S. holder owns our ADSs, we will continue to be treated as a PFIC with respect to such
U.S. holder in all succeeding taxable years during which such U.S. holder owns the ADSs, regardless of whether we continue to qualify as a PFIC, unless
we cease to be a PFIC and such U.S. holder has made a “deemed sale” election. If a deemed sale election is made, such U.S. holder will be deemed to have
sold the ADSs at their fair market value and any gain from such deemed sale would be subject to the special tax regime described below. After the deemed
sale election, as long as we do not become a PFIC in a subsequent taxable year, such U.S. holder’s ADSs with respect to which such election was made will
not be treated as

130

ADSs in a PFIC and such U.S. holder will not be subject to the special tax regime described below. U.S. holders should consult their tax advisors as to the
possibility and tax consequences of making a deemed sale election if we are a PFIC and cease to be a PFIC and such election becomes available.

If we are a PFIC in any taxable year during which a U.S. holder owns our ADSs, such U.S. holder generally will be subject to the following special tax
regime, which applies to both (a) any “excess distribution” by us to such U.S. holder (generally, such U.S. holder's ratable portion of distributions in any
taxable year which are greater than 125% of the average annual distribution received by such U.S. holder in the shorter of the three preceding taxable years
or such U.S. holder's holding period for the ADSs) and (b) any gain realized on the sale or other disposition of the ADSs. Under this regime, any excess
distribution or gain will be treated as ordinary income and will be subject to tax as if (i) the excess distribution or gain had been realized ratably over such
U.S. holder's holding period, (ii) the amount deemed realized in each taxable year had been subject to tax in each taxable year of that holding period at the
highest marginal rate for such year (other than income allocated to the current period or any taxable period before we became a PFIC, which would be
subject to tax at the U.S. holder’s regular ordinary income rate for the current taxable year and would not be subject to the interest charge described in the
next clause) and (iii) the interest charge generally applicable to underpayments of tax had been imposed on the taxes deemed to have been payable in those
taxable  years.  In  addition,  dividend  distributions  made  to  such  U.S.  holder  will  not  qualify  for  the  preferential  rates  of  taxation  currently  applicable  to
"qualified dividend income" discussed below under “Distributions.”

Certain elections, if available, may be made to alleviate some of the adverse tax consequences of PFIC status and, if made, would result in an alternative
tax treatment of the acquisition, ownership and disposition of ADSs in a PFIC. If we are a PFIC for any taxable year during which a U.S. holder owns our
ADSs and the U.S. holder makes a mark-to-market election, the U.S. holder generally will recognize as ordinary income any excess of the fair market value
of the ADSs at the end of each taxable year over their adjusted tax basis, and will recognize an ordinary loss in respect of any excess of the adjusted tax
basis of the ADSs over their fair market value at the end of the taxable year (but only to the extent of the net amount of income previously included as a
result of the mark-to-market election). In addition, the U.S. holder’s tax basis in the ADSs will be adjusted to reflect these income or loss amounts. Any
gain or loss recognized on the sale or other disposition of the ADSs in a taxable year when we are a PFIC will be treated as ordinary income or loss (but, in
the case of loss, only to the extent of the net amount of income previously included as a result of the mark-to-market election), respectively. The mark-to-
market election is available only if we are a PFIC and the ADSs are “regularly traded” on a “qualified exchange.” The ADSs will be treated as “regularly
traded” in any calendar year in which more than a de minimis quantity of the ADSs are traded on a qualified exchange on at least 15 days during each
calendar quarter (subject to the rule that trades that have as one of their principal purposes the meeting of the trading requirement are disregarded). The
Nasdaq Global Select Market is a qualified exchange for this purpose and, consequently, if the ADSs are regularly traded, the mark-to-market election will
be available to the U.S. holder.

If we are a PFIC for any taxable year during which a U.S. holder owns our ADSs, we expect to provide such U.S. holder, upon request, a “PFIC Annual
Information Statement” with the information required to allow such U.S. holder to make a “qualified electing fund election” or “QEF Election.”

If a U.S. holder makes a QEF Election, the U.S. holder will be subject to current taxation on its pro rata share of our ordinary earnings and net capital gain
for  each  taxable  year  that  we  are  classified  as  a  PFIC.  Furthermore,  any  distributions  paid  by  us  out  of  our  earnings  and  profits  that  were  previously
included in the U.S. holder’s income under the QEF Election will not be taxable to the U.S. holder. The U.S. holder will increase its tax basis in its ADSs
by  an  amount  equal  to  any  income  included  under  the  QEF  Election  and  will  decrease  its  tax  basis  by  any  amount  distributed  on  the  ADSs  that  is  not
included in the U.S. holder’s income. In addition, the U.S. holder will recognize capital gain or loss on the disposition of its ADSs in an amount equal to
the difference between the amount realized and the U.S. holder’s adjusted tax basis in the ADSs. If the U.S. holder does not make and maintain a QEF
election for the U.S. holder’s entire holding period for our ADSs by making the election for the first taxable year in which the U.S. holder acquired our
ADSs, the U.S. holder will be subject to the special tax regime discussed above, unless the U.S. holder can properly make a “purging election” with respect
to our ADSs in connection with the U.S. Shareholder’s QEF Election. A purging election may require the U.S. holder to recognize taxable gain on the U.S.
holder’s ADSs. No purging election is necessary for a U.S. holder that timely makes a QEF Election for the first taxable year in which the U.S. holder
acquired our ADSs.

U.S.  holders  should  consult  their  tax  advisors  to  determine  whether  any  of  the  elections  discussed  above  would  be  available  and,  if  so,  what  the  tax
consequences of the alternative tax treatments would be in their particular circumstances.

If we are a PFIC for any taxable year during which a U.S. holder owns our ADSs, such U.S. holder generally will be subject to similar rules with respect to
distributions  we  receive  from  and  gains  we  recognize  on  the  sale  or  other  disposition  of  the  stock  any  of  our  subsidiaries  that  are  PFICs,  or  lower-tier
PFICs, as if such distributions were indirectly received by or such sale or other disposition was indirectly carried out by such U.S. holder. U.S. holders
should consult their tax advisors as to the application of the lower-tier PFIC rules in their particular circumstances.

131

If  a  U.S.  holder  owns  ADSs  during  any  taxable  year  in  which  we  are  a  PFIC,  the  U.S.  holder  generally  will  be  required  to  file  an  IRS  Form  8621
(Information Return by a Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund) with respect to us, generally with the U.S.
holder’s U.S. federal income tax return for that taxable year. U.S. holders should consult their tax advisors concerning PFIC reporting requirements in their
particular circumstances.

The  U.S.  federal  income  tax  rules  relating  to  PFICs  are  complex.  U.S.  holders  are  urged  to  consult  their  tax  advisers  with  respect  to  the
acquisition, ownership and disposition of our ADSs, the tax consequences to them of an investment in a PFIC, any elections available with respect
to the ADSs and the IRS information reporting obligations with respect to the acquisition, ownership and disposition of the ADSs.

Distributions. We do not expect to make any distribution in respect of our ADSs. Subject to the discussion above under “—Passive  Foreign  Investment
Company Considerations,” if we make any distribution in respect of our ADSs, the gross amount of the distribution (including any amounts of foreign tax
withheld in respect of such distribution) actually or constructively received by a U.S. holder with respect to the ADSs will be taxable to the U.S. holder as a
dividend to the extent of the U.S. holder’s pro rata share of our current or accumulated earnings and profits, as determined under U.S. federal income tax
principles. Distributions in excess of earnings and profits will be non-taxable to the U.S. holder to the extent of, and will be applied against and reduce, the
U.S. holder’s adjusted tax basis in the ADSs. Distributions in excess of earnings and profits and such adjusted tax basis will generally be taxable to the U.S.
holder  as  either  long-term  or  short-term  capital  gain  depending  upon  whether  the  U.S.  holder's  holding  period  exceeds  one  year  as  of  the  time  such
distribution  is  received.  However,  since  we  do  not  calculate  our  earnings  and  profits  under  U.S.  federal  income  tax  principles,  it  is  expected  that  any
distribution will be reported as a dividend, even if that distribution would otherwise be treated as a non-taxable return of capital or as capital gain under the
rules described above. Non-corporate U.S. holders may qualify for the preferential rates of taxation with respect to dividends on ADSs applicable to long-
term capital gains (i.e., gains from the sale of capital assets held for more than one year) applicable to "qualified dividend income" (as discussed below) if
we are a “qualified foreign corporation” and certain other requirements (discussed below) are met. A non-U.S. corporation (other than a corporation that is
classified as a PFIC for the taxable year in which the dividend is paid or the preceding taxable year) generally will be considered to be a qualified foreign
corporation (a) if it is eligible for the benefits of a comprehensive tax treaty with the United States which the Secretary of Treasury of the United States
determines is satisfactory for purposes of this purpose and which includes an exchange-of-information provision or (b) with respect to any dividend it pays
on ADSs which are readily tradable on an established securities market in the United States. Our ADSs are currently listed on the Nasdaq Global Select
Market, which is an established securities market in the United States, and we currently expect the ADSs to be readily tradable on the Nasdaq Global Select
Market. However, there can be no assurance that the ADSs will be considered readily tradable on an established securities market in the United States in
later taxable years. The Company, which is incorporated under the laws of France, believes that it qualifies as a resident of France for purposes of, and is
eligible for the benefits of, the Convention between the Government of the United States of America and the Government of the French Republic for the
Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Income and Capital, signed on August 31, 1994, as amended
and  currently  in  force,  or  the  U.S.-France  Tax  Treaty,  although  there  can  be  no  assurance  in  this  regard.  Further,  the  IRS  has  determined  that  the  U.S.-
France Tax Treaty is satisfactory for purposes of the qualified dividend income rules and that it includes an exchange-of-information program. Therefore,
subject to the discussion above under “—Passive Foreign Investment Company Considerations,” dividend distributions with respect to our ADSs generally
will be “qualified dividend income” in the hands of individual U.S. holders, provided that a holding period requirement (more than 60 days of ownership,
without protection from the risk of loss, during the 121-day period beginning 60 days before the ex-dividend date) and certain other requirements are met.
Such dividends will not be eligible for the dividends-received deduction generally allowed to corporate U.S. holders.

A U.S. holder generally may claim the amount of any French withholding tax as either a deduction from gross income or a credit against its U.S. federal
income tax liability, subject to generally applicable limitations. Generally, the credit is determined separately for different categories of income and cannot
exceed the proportionate share of a U.S. holder’s U.S. federal income tax liability that such U.S. holder’s taxable income from foreign sources bears to such
U.S.  holder’s  worldwide  taxable  income.  For  foreign  tax  credit  limitation  purposes,  dividend  distributions  with  respect  to  our  ADSs  generally  will  be
treated as passive category income from foreign sources. The amount of a distribution with respect to the ADSs that is treated as a “dividend” may be lower
for U.S. federal income tax purposes than it is for French income tax purposes, potentially resulting in a reduced foreign tax credit for the U.S. holder. U.S.
holders should consult their tax advisors regarding the foreign tax credit rules.

In  general,  the  amount  of  a  distribution  paid  to  a  U.S.  holder  in  a  foreign  currency  will  be  the  U.S.  dollar  value  of  the  foreign  currency  calculated  by
reference to the spot exchange rate on the day the Depositary receives the distribution, regardless of whether the foreign currency is converted into U.S.
dollars at that time. Any foreign currency gain or loss a U.S. holder realizes on a subsequent conversion of foreign currency into U.S. dollars will be U.S.
source  ordinary  income  or  loss.  If  dividends  received  in  a  foreign  currency  are  converted  into  U.S.  dollars  on  the  day  they  are  received,  a  U.S.  holder
should not be required to recognize foreign currency gain or loss in respect of the dividend.

132

Sale, Exchange or Other Taxable Disposition of the ADSs. A U.S. holder generally will recognize gain or loss for U.S. federal income tax purposes upon
the sale, exchange or other taxable disposition of ADSs in an amount equal to the difference between the U.S. dollar value of the amount realized from
such sale or exchange and the U.S. holder’s adjusted tax basis in those ADSs, determined in U.S. dollars. Subject to the discussion above under “—Passive
Foreign Investment Company Considerations,” this gain or loss generally will be capital gain or loss. The adjusted tax basis in the ADSs generally will be
equal  to  the  cost  of  such  ADSs.  Capital  gain  from  the  sale,  exchange  or  other  taxable  disposition  of  ADSs  of  a  non-corporate  U.S.  holder  is  generally
eligible for a preferential rate of taxation applicable to capital gains, if the non-corporate U.S. holder’s holding period determined at the time of such sale,
exchange or other taxable disposition for such ADSs exceeds one year (i.e., such gain is long-term taxable gain). The deductibility of capital losses for U.S.
federal income tax purposes is subject to limitations. Any such gain or loss that a U.S. holder recognizes generally will be treated as U.S. source gain or
loss for foreign tax credit limitation purposes.

For a cash basis taxpayer, units of foreign currency paid or received are translated into U.S. dollars at the spot rate on the settlement date of the purchase or
sale. In that case, no foreign currency exchange gain or loss will result from currency fluctuations between the trade date and the settlement date of such a
purchase or sale. An accrual basis taxpayer, however, may elect the same treatment required of cash basis taxpayers with respect to purchases and sales of
the ADSs that are traded on an established securities market, provided that the election is applied consistently from year to year. Such election may not be
changed without the consent of the IRS. For an accrual basis taxpayer who does not make such election, units of foreign currency paid or received are
translated into U.S. dollars at the spot rate on the trade date of the purchase or sale. Such an accrual basis taxpayer may recognize exchange gain or loss
based on currency fluctuations between the trade date and the settlement date. Any foreign currency gain or loss a U.S. Holder realizes will be U.S. source
ordinary income or loss.

Backup Withholding and Information Reporting. U.S. holders generally will be subject to information reporting requirements with respect to dividends
on  ADSs  and  on  the  proceeds  from  the  sale,  exchange  or  disposition  of  ADSs  that  are  paid  within  the  United  States  or  through  U.S.-related  financial
intermediaries, unless the U.S. holder is an “exempt recipient.” In addition, U.S. holders may be subject to backup withholding on such payments, unless
the U.S. holder provides a taxpayer identification number and a duly executed IRS Form W-9 or otherwise establishes an exemption. Backup withholding
is not an additional tax, and the amount of any backup withholding will be allowed as a credit against a U.S. holder’s U.S. federal income tax liability and
may entitle such holder to a refund, provided that the required information is timely furnished to the IRS.

Furthermore, certain individual U.S. holders are required to report information relating to an interest in ADSs, subject to certain exceptions (including an
exception for shares held in accounts maintained by U.S. financial institutions) by filing IRS Form 8938 (Statement of Specified Foreign Financial Assets)
with their U.S. federal income tax return.

U.S. holders are urged to consult their tax advisors regarding their information reporting obligations, if any, with respect to their acquisition, ownership and
disposition of our ADSs.

THE DISCUSSION ABOVE IS A SUMMARY OF CERTAIN MATERIAL U.S. FEDERAL INCOME AND FRENCH TAX CONSEQUENCES
OF AN INVESTMENT IN OUR ADSs AND IS NOT TAX ADVICE. U.S. HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS
REGARDING  THE  TAX  CONSEQUENCES  TO  THEM  OF  AN  INVESTMENT  IN  OUR  ADSs  IN  LIGHT  OF  THEIR  PARTICULAR
CIRCUMSTANCES.

Item 11.Quantitative and Qualitative Disclosures About Market Risk.

Liquidity Risk

As of December 31, 2021, our cash and cash equivalents were €33.7 million ($38.1 million) and were primarily cash and term deposits that are convertible
into  cash  in  approximately  30  days  notice  without  penalty.  We  believe  that  our  cash  and  cash  equivalents  as  of  December  31,  2021  together  with  the
proceed of the sale of the Group's US production unit located in Princeton, a sale completed in April 2022, for a gross amount of 44.5 million dollars (41.1
million euros) enable us to cover our cash requirements until mid-2024.

In  the  longer  term  the  Group  will  need  to  seek  additional  funds,  through  public  or  private  equity  or  debt  financings,  government  or  other  third-party
funding,  marketing  and  distribution  arrangements  and  other  collaborations,  strategic  alliances  and  licensing  arrangements  or  a  combination  of  these
approaches.

However, no assurance can be given at this time as to whether we will be able to achieve these financing objectives.

Foreign Currency Exchange Risk

We use the euro as our functional currency for our financial communications. However, a significant portion of our expenses, financial assets and liabilities
are  denominated  in  U.S  dollars  and  are  exposed  to  changes  in  foreign  currency  exchange  rates.  We  also  entered  into  a  license  agreement  with  SQZ
Biotechnologies in 2019 and any potential revenues pursuant to this agreement will be made in U.S. dollars.

We do not currently engage in hedging transactions or the use of forward contracts but may in the future in order to minimize the impact of uncertainty in
future exchange rates on cash flows. A deterioration of the U.S dollar to the Euro exchange rate of 1.1326 used for 2021 closing could impact our financial
statements as follows:

As we advance our clinical development in the United States and potentially commercialize our product candidates in that market, we expect to face greater
exposure to exchange rate risk and would then consider using exchange rate derivative or hedging techniques at that time. We expect to continue to enter
into transactions based in foreign currencies that could be impacted by changes in exchange rates.

Equity risk

134

The Company's exposure to equity risk is limited to its own shares and linked to the OCABSA agreement. The total amount that could be issued under this
agreement is subject to the regulatory limit of 20% dilution. As the share price of the Company has an impact on the number of shares issued upon the
conversion of the convertible notes, the contractual possibility to raise up to €33.0 million will depend on the share price of the company. Based on the
closing  market  price  the  day  before  the  approval  date  of  the  Consolidated  Financial  Statements  (€1.28),  the  Company  could  raise  approximately  €3.0
million. A change in the share price used could change the amount that could be raised as follows:

We believe we have very low exposure to interest rate risk. Such exposure primarily involves our money market funds and time deposit accounts. Changes
in interest rates have a direct impact on the rate of return on these investments and the cash flows generated.

The outstanding bank loans bear interest at a fixed rate, and therefore we are not subject to interest rate risk with respect to this loan.

Credit Risk

We believe that the credit risk related to our cash and cash equivalents is not significant in light of the quality of the financial institutions at which such
funds are held.

12.D. American Depositary Shares.

The Bank of New York Mellon acts as the depositary for the American Depositary Shares. The Bank of New York Mellon’s depositary offices are located
at 240 Greenwich Street, New York, New York 10286. American Depositary Shares are frequently referred to as ADSs and represent ownership interests in
securities that are on deposit with the depositary. ADSs may be evidenced by certificates that are commonly known as American Depositary Receipts, or
ADRs. The depositary typically appoints a custodian to safekeep the securities on deposit. In this case, the custodian is Société Générale. The Company has
appointed  The  Bank  of  New  York  Mellon  as  depositary  pursuant  to  an  amended  and  restated  deposit  agreement.  A  copy  of  the  amended  and  restated
deposit  agreement  is  on  file  with  the  SEC  under  cover  of  a  Registration  Statement  on  Form  F-3.  ADS  holders  may  obtain  a  copy  of  the  amended  and
restated deposit agreement from the SEC’s website (www.sec.gov) and should refer to Registration Number 333-259690 when retrieving such copy.

An owner of ADSs may hold its ADSs either (1) directly (a) by having an ADR, which is a certificate evidencing a specific number of ADSs, registered in
such owner’s name, or (b) by having uncertificated ADSs registered in the owner’s name in the Direct Registration System, or DRS, or (2) indirectly by
holding a security entitlement in ADSs through the owner’s broker or other financial institution that is a direct or indirect participant in the Depository
Trust Company, or DTC. If an owner of ADSs decides to hold its ADSs directly, such owner is a registered ADS holder, also referred to as an ADS holder.
This description assumes all owners are an ADS holder. If an owner of ADSs decides to hold the ADSs indirectly, such owner must rely on the procedures
of its broker or other financial institution to assert the rights of ADS holders described in this section. Such indirect holder should consult with its broker or
financial institution to find out what those procedures are. DRS is a system administered by DTC pursuant to which the depositary

135

may register the ownership of uncertificated ADSs, which ownership is confirmed by periodic statements sent by the depositary to the registered holders of
uncertificated ADSs.

An  ADS  holder  will  not  be  treated  as  one  of  the  Company’s  shareholders  and  such  ADS  holder  will  not  have  shareholder  rights.  French  law  governs
shareholder rights. The depositary will be the holder of the ordinary shares underlying each owner’s ADSs. A holder of ADSs will have ADS holder rights.
An amended and restated deposit agreement among the Company, the depositary and all persons directly and indirectly holding ADSs sets out ADS holder
rights as well as the rights and obligations of the depositary. New York law governs the amended and restated deposit agreement and the ADRs. In the
event of any discrepancy between the ADRs and the amended and restated deposit agreement, the amended and restated deposit agreement governs. The
following is a summary of the material provisions of the amended and restated deposit agreement. More complete information is contained in the amended
and  restated  deposit  agreement  and  the  form  of  ADR.  Members  of  the  public  may  obtain  copies  of  those  documents  from  the  SEC’s  website  at
www.sec.gov. A copy of the amended and restated deposit agreement is also filed as an exhibit to the Company’s Annual Report on Form 20-F to which
this description is also an exhibit.

Fees and Expenses

Pursuant  to  the  terms  of  the  amended  and  restated  deposit  agreement,  the  holders  of  our  ADSs  will  be  required  to  pay  the  following  fees
Persons depositing or withdrawing ordinary shares or ADSs
must pay:

taxes, stamp duty or withholding taxes

• 

 As necessary

Any charges payable by the depositary, custodian or their agents in
connection with the servicing of deposited securities

• 

 As necessary

The depositary collects its fees for delivery and surrender of ADSs directly from investors depositing ordinary shares or surrendering ADSs for the purpose
of withdrawal or from intermediaries acting for them. The depositary collects fees for making distributions to investors by deducting those fees from the
amounts distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its annual fee for depositary services by
deduction  from  cash  distributions  or  by  directly  billing  investors  or  by  charging  the  book-entry  system  accounts  of  participants  acting  for  them.  The
depositary may collect any of its fees by deduction from any cash distribution payable to ADS holders that are obligated to pay those fees. The depositary
may generally refuse to provide for-fee services until its fees for those services are paid.

From time to time, the depositary may make payments to the Company to reimburse or share revenue from the fees collected from ADS holders, or waive
fees and expenses for services provided, generally relating to costs and expenses arising out of establishment and maintenance of the ADS program. In
performing  its  duties  under  the  amended  and  restated  deposit  agreement,  the  depositary  may  use  brokers,  dealers,  foreign  currency  or  other  service
providers that are affiliates of the depositary and that may earn or share fees, spreads or commissions.

The depositary may convert foreign currency itself or through any of its affiliates and, in those cases, acts as principal for its own account and not as agent,
advisor, broker or fiduciary on behalf of any other person and earns revenue, including, without limitation, transaction spreads, that it will retain for its own
account.  The  revenue  is  based  on,  among  other  things,  the  difference  between  the  exchange  rate  assigned  to  the  currency  conversion  made  under  the
amended  and  restated  deposit  agreement  and  the  rate  that  the  depositary  or  its  affiliate  receives  when  buying  or  selling  foreign  currency  for  its  own
account.  The  depositary  makes  no  representation  that  the  exchange  rate  used  or  obtained  in  any  currency  conversion  under  the  amended  and  restated
deposit agreement will be the most

137

 
 
 
 
 
 
 
 
favorable rate that could be obtained at the time or that the method by which that rate will be determined will be the most favorable to holders of ADSs,
subject  to  the  depositary’s  obligations  under  the  amended  and  restated  deposit  agreement.  The  methodology  used  to  determine  exchange  rates  used  in
currency conversions is available upon request.

Payment of Taxes

ADS holders will be responsible for any taxes or other governmental charges payable on their ADSs or on the deposited securities represented by any of
such holder’s ADSs. The depositary may refuse to register any transfer of a holder’s ADSs or allow them to withdraw the deposited securities represented
by such holder’s ADSs until such taxes or other charges are paid. It may apply payments owed to ADS holders or sell deposited securities represented by
such  holder’s  ADSs  to  pay  any  taxes  owed  and  such  holder  will  remain  liable  for  any  deficiency.  If  the  depositary  sells  deposited  securities,  it  will,  if
appropriate, reduce the number of ADSs registered in the ADS holder’s name to reflect the sale and pay to such holder any net proceeds, or send such
holder any property, remaining after it has paid the taxes. An ADS holder’s obligation to pay taxes and indemnify the Company and the depository against
any tax claims will survive the transfer or surrender of such holder’s ADSs, the withdrawal of the deposited ordinary shares as well as the termination of
the amended and restated deposit agreement.

Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer (principal executive officer) and our chief financial officer and chief operating officer
(principal financial officer), has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13(a) - 15(e) and
15(d) - 15(e) under the Securities Exchange Act of 1934, as amended), as of December 31, 2021. Based on such evaluation, our principal executive officer
and  principal  financial  officer  have  concluded  that  our  disclosure  controls  and  procedures  were  not  effective  at  the  reasonable  assurance  level  as  of
December 31, 2021 as a result of the material weakness described below. We are undertaking the remedial steps to address the material weakness in our
disclosure controls and procedures as set forth below under “Management’s Plan for Remediation of the Current Material Weakness.”

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal controls over financial reporting (as defined in Rules 13a-15(f) and 15d-
15(f)  under  the  Exchange  Act)  and  for  the  assessment  of  the  effectiveness  of  our  internal  control  over  financial  reporting.  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.

Under the supervision and with the participation of our chief executive officer (principal executive officer) and chief financial officer and chief operating
officer  (principal  financial  officer),  management  conducted  an  assessment  of  our  internal  control  over  financial  reporting  based  upon  the  framework  in
Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). A material
weakness  is  a  deficiency,  or  a  combination  of  deficiencies,  in  internal  control  over  financial  reporting,  such  that  there  is  a  reasonable  possibility  that  a
material misstatement of our financial statements will not be prevented or detected on a timely basis.

As of December 31, 2019 and December 31, 2020, our management concluded that our internal control over financial reporting was not effective as a result
of two material weaknesses in our internal control over financial reporting related to: (i) the monitoring of research and development projects, as controls
designed to track actual costs incurred against invoices received were not operating at a sufficient level of precision due to insufficient personnel with an
appropriate level of knowledge and training in internal control over complex processes; and (ii) the lack of sufficiently developed and documented internal
controls for our U.S. subsidiary. These material

138

weaknesses had been initially identified in connection with the preparation of our financial results for the year ended December 31, 2018.

In  connection  with  our  assessment  as  of  December  31,  2021,  our  management  concluded  that  the  material  weakness  related  to  the  lack  of  sufficiently
developed and documented internal controls for our U.S. subsidiary had been remediated. However, we concluded that that the material weakness related to
the monitoring of research and development projects was not fully remediated.

During  2021,  we  continued  to  strengthen  our  internal  controls  over  research  and  development  financial  information,  in  particular  we  finalized  the
implementation of controls designed to track actual costs incurred against invoices received, in order to better detect and correct errors. During 2021, we
also trained personnel on internal controls over complex processes.

We believe the remediation measures described above improved the reliability of financial information related to research and development. Nevertheless,
our management identified that the control over the reconciliation of estimated hospital costs incurred related to clinical trials sponsored by the Company
with invoices received did not operate at a sufficient level of precision. Management considers this control have to be redesigned to fully remediate the
material  weakness.  As  a  result  of  this  material  weakness,  management  concluded  our  internal  control  over  financial  reporting  was  not  effective  as  of
December 31, 2021 at the reasonable assurance level.

Notwithstanding  the  material  weakness,  our  management  has  concluded  that  the  financial  statements  included  elsewhere  in  this  Annual  Report  present
fairly, in all material respects, our financial position, results of operations and cash flows for the periods presented in conformity with IFRS.

Our independent registered public accounting firm has not assessed the effectiveness of our internal control over financial reporting, which may increase
the risk that weaknesses or deficiencies in our internal control over financial reporting go undetected.

Management’s Plan for Remediation of the Current Material Weakness

To further improve our internal control over financial reporting and to specifically address the control deficiency that led to our material weakness, we plan
to deploy remediation efforts focused on reinforcing:

•

controls  over  our  research  and  development  financial  information,  including  redesigning  our  key  control  over  the  reconciliation  of  invoices
received with estimated hospital costs incurred related to clinical trials sponsored by the Company so that it can operate at an appropriate level of
precision to detect and correct errors.

Remediation of Previously Identified Material Weakness in Internal Control over Financial Reporting

Management previously identified a material weakness in our internal control over financial reporting that was identified in connection with the preparation
of  the  financial  results  for  the  year  ended  December  31,2018  which  had  not  been  remediated  as  of  December  31,  2020.  As  a  result  of  the  remediation
activities  described  below,  as  of  December  31,  2021,  management  has  concluded  that  the  previously  disclosed  material  weakness  has  been  fully
remediated.

This material weakness previously identified in our internal control over financial reporting related to the lack of sufficiently developed and documented
internal controls for our U.S. subsidiary.

In response to the identified material weakness, we took a number of actions to improve our internal control over the financial reporting during the year
ended December 31, 2021, including the following:

•

•

the reinforcement and structuration of the US finance team, including the hiring of a new staff accountant in March 2021. This new hire allowed
us  to  maintain  a  better  segregation  of  duties  within  our  US  subsidiary  and  to  implement  new  effective  controls  to  mitigate  the  residual  risk  of
material misstatements in our financial reporting.

the implementation of new effective controls over certain relevant information technology (“IT”) systems supporting our U.S. operations that are
relevant to the preparation of the consolidated financial statements with a specific focus on user access controls.

Attestation Report of the Registered Public Accounting Firm

This Annual Report does not include an attestation report of our registered public accounting firm due to a transition period established by rules of the
Securities and Exchange Commission for emerging growth companies.

Changes in Internal Control over Financial Reporting

Other  than  the  remediation  activities  described  above,  there  were  no  changes  in  our  internal  control  over  financial  reporting  during  the  year  ended
December 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

“All Other Fees” are additional amounts billed for products and services provided by KPMG.

There were no “Tax Fees” billed or paid during 2020 or 2021.

Audit and Non-Audit Services Pre-Approval Policy

The audit committee has responsibility for appointing, setting compensation of and overseeing the work of the independent registered public accounting
firm. In recognition of this responsibility, the audit committee has adopted a policy governing the pre-approval of all audit and permitted non-audit services
performed by our independent registered public accounting firm to ensure that the provision of such services does not impair the independent registered
public  accounting  firm’s  independence  from  us  and  our  management.  Unless  a  type  of  service  to  be  provided  by  our  independent  registered  public
accounting firm has received general pre-approval from the audit committee, it requires specific pre-approval by the audit committee. The payment for any
proposed services in excess of pre-approved cost levels requires specific pre-approval by the audit committee.

140

Pursuant to its pre-approval policy, the audit committee may delegate its authority to pre-approve services to the chairperson of the audit committee. The
decisions of the chairperson to grant pre-approvals must be presented to the full audit committee at its next scheduled meeting. The audit committee may
not delegate its responsibilities to pre-approve services to the management.

The audit committee has considered the non-audit services provided by KPMG as described above and believes that they are compatible with maintaining
KPMG’s independence as our independent registered public accounting firm.

Corporate Governance.

As a French société anonyme, we are subject to various corporate governance requirements under French law. In addition, as a foreign private issuer listed
on  the  Nasdaq  Global  Select  Market,  we  are  subject  to  Nasdaq  corporate  governance  listing  standards.  However,  the  corporate  governance  standards
provide that foreign private issuers are permitted to follow home country corporate governance practices in lieu of Nasdaq rules, with certain exceptions.
We  currently  rely  on  these  exemptions  for  foreign  private  issuers  and  follow  French  corporate  governance  practices  in  lieu  of  the  Nasdaq  corporate
governance  rules,  which  would  otherwise  require  that  (1)  a  majority  of  our  board  of  directors  consist  of  independent  directors;  (2)  we  establish  a
nominating and corporate governance committee; and (3) our remuneration committee be composed entirely of independent directors.

The following are the significant ways in which our corporate governance practices differ from those required for U.S. companies listed on Nasdaq:

As a foreign private issuer, we are required to comply with Rule 10A-3 of the Exchange Act, relating to audit committee composition and responsibilities.
Rule  10A-3  provides  that  the  audit  committee  must  have  direct  responsibility  for  the  nomination,  compensation  and  choice  of  our  auditors,  as  well  as
control  over  the  performance  of  their  duties,  management  of  complaints  made,  and  selection  of  consultants.  However,  if  the  laws  of  a  foreign  private
issuer’s  home  country  require  that  any  such  matter  be  approved  by  the  board  of  directors  or  the  shareholders,  the  audit  committee’s  responsibilities  or
powers with respect to such matter may instead be advisory. Under French law, the audit committee may only have an advisory role and appointment of our
statutory auditors, in particular, must be decided by the shareholders at our annual meeting.

In addition, Nasdaq rules require that a listed company specify that the quorum for any meeting of the holders of common stock be at least 33 / % of the
outstanding  shares  of  the  company’s  voting  stock.  Consistent  with  French  law,  our  bylaws  provide  that  a  quorum  requires  the  presence  of  shareholders
having at least (1) 20% of the shares entitled to vote in the case of an ordinary shareholders’ general meeting or at an extraordinary shareholders’ general
meeting where shareholders are voting on a capital increase by capitalization of reserves, profits or share premium, or (2) 25% of the shares entitled to vote
in the case of any other extraordinary shareholders’ general meeting. If a quorum is not present, the meeting is adjourned. There is no quorum requirement
when  an  ordinary  general  meeting  is  reconvened,  but  the  reconvened  meeting  may  consider  only  questions  which  were  on  the  agenda  of  the  adjourned
meeting. When an extraordinary general meeting is reconvened, the quorum required is 20% of the shares entitled to vote, except where the reconvened
meeting  is  considering  capital  increases  through  capitalization  of  reserves,  profits  or  share  premium.  For  these  matters,  no  quorum  is  required  at  the
reconvened meeting. If a quorum is not present at a reconvened meeting requiring a quorum, then the meeting may be adjourned for a maximum of two
months.

Furthermore, we follow French corporate governance practices in lieu of the Nasdaq corporate governance rules that require shareholder approval prior to
specified  issuances  of  securities.  More  specifically,  Nasdaq  Marketplace  Rule  5635  requires  a  U.S.  domestic  listed  company  to  obtain  shareholder
approval:  (1)  prior  to  the  issuance  of  securities  when  the  issuance  or  potential  issuance  will  result  in  a  change  of  control  of  the  issuer;  (2)  prior  to  the
issuance of securities in connection with a transaction other than a public offering involving the sale, issuance or potential issuance by the issuer alone, or
together with sales by its officers, directors or substantial shareholders, of common stock (or securities convertible into or exercisable for common stock)
equal to 20% or more of the common stock or 20% or more of the voting power outstanding before the issuance for less than the greater of book or market
value; and (3) prior to the issuance of securities when an equity compensation arrangement is made or materially amended, including

141

prior to the issuance of common stock to the issuer’s officers, director, employees or consultants for less than the greater of book or market value. While
French  law  requires  a  French  company  to  obtain  prior  shareholder  approval  to  issue  shares,  its  shareholders  may  pre-authorize  the  company’s  board  of
directors to issue shares such that shareholder approval is not required at the time of issuance.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors,

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated statements of financial position of Erytech Pharma S.A. and subsidiary (the Company) as of December 31,
2021, 2020 and 2019, the related consolidated statements of income (loss), comprehensive income (loss), changes in 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). In our
opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021, 2020
and 2019, 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
International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”).

Basis for Opinion

These  consolidated  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to  express  an  opinion  on  these
consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board
(United  States)  (PCAOB)  and  are  required  to  be  independent  with  respect  to  the  Company  in  accordance  with  the  U.S.  federal  securities  laws  and  the
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance  about  whether  the  consolidated  financial  statements  are  free  of  material  misstatement,  whether  due  to  error  or  fraud.  The  Company  is  not
required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain
an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal
control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or
fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and
disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by
management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis
for our opinion.

We have served as the Company’s auditor since 2004.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

The  notes  are  an  integral  part  of  the  accompanying  Consolidated  Financial  Statements.  The  Consolidated  Financial  Statements  were  approved  and
authorized for issuance by the Board of Directors on April 26, 2022.

1. DESCRIPTION OF THE BUSINESS

ERYTECH Pharma S.A. (“ERYTECH,” and together with its subsidiary the “Company”) is incorporated in Lyon, France, and was founded in 2004 to
develop and market innovative red blood cell-based therapeutics for cancer and orphan diseases.

The  Company  completed  its  initial  public  offering  on  Euronext  Paris  in  May  2013,  raising  €17.7  million,  and  on  the  Nasdaq  Global  Select  Market  in
November 2017, raising €124.0 million ($144.0 million on a gross basis before deducting offering expenses).

The Company has incurred losses and negative cash flows from operating activities since its inception and had shareholders’ equity of €22,845 thousand as
of December 31, 2021 as a result of several financing rounds, including an initial public offering. The Company anticipates incurring additional losses until
such time, if ever, that it can generate significant revenue from its product candidates in development.

The COVID-19 pandemic have resulted in a delay in patient enrollment in the TRYbeCA-1 trial in 2020 and thus in the interim analysis that occured in
February 2021.We reported top-line final results on October 25, 2021. The Phase 3 TRYbeCA-1 trial did not meet the primary efficacy endpoint of overall
survival (OS). Nevertheless, a preliminary analysis of the results of a subgroup of patients indicated a potential efficacy signal for patients treated with
eryaspase in combination with FOLFIRI chemotherapy cocktail.

The  Company’s  future  operations  are  highly  dependent  on  a  combination  of  factors,  including:  (i)  the  success  of  its  research  and  development;
(ii)  regulatory  approval  and  market  acceptance  of  the  Company’s  proposed  future  products;  (iii)  the  timely  and  successful  completion  of  additional
financing;  and  (iv)  the  development  of  competitive  therapies  by  other  biotechnology  and  pharmaceutical  companies.  As  a  result,  the  Company  is  and
should continue, in the short to mid-term, to be financed through partnership agreements for the development and commercialization of its drug candidates
and through the issuance of new debt or equity instruments.

The situation on the financial markets and TRYBeCA-1 study result may impair the ability of the Company to raise capital when needed or on attractive
terms.

The accompanying consolidated financial statements and related notes (the “Consolidated Financial Statements”) present the operations of ERYTECH
Pharma S.A. and its subsidiary, ERYTECH Pharma, Inc.

Registered office of ERYTECH Pharma S.A.: 60 avenue Rockefeller, 69008, Lyon, France.

Major events of 2020

Business

February 2020:

•

•

The Company received from Bpifrance a reimbursable advance of €2,979 thousand and a subsidy of €294 thousand (recorded in 2019) under the
milestone n°6 of the TEDAC project.

The Company entered into a strategic partnership with the German Red Cross Blood Donor Service Baden-W✔rttemberg-Hessen (GRCBDS) for
the supply of donor red blood cells to manufacture its product candidates, including eryaspase, in Europe and to complement the existing alliance
with the French Blood Bank (EFS).

March 2020:

•

•

The  TRYbeCA-1  trial  has  continued  to  progress  despite  the  challenges  caused  by  the  impact  of  the  COVID-19  global  pandemic,  and  patient
enrollment has continued notwithstanding the increasing difficulties experienced by hospitals to organize the proper treatment and follow-up.

The  independent  data  monitoring  committee  (IDMC)  of  the  TRYbeCA-1  trial  reviewed  the  safety  data  of  the  first  320  patients  enrolled  and
treated.  In  line  with  the  two  earlier  safety  reviews  of  the  trial,  no  safety  issues  were  identified,  and  the  IDMC  recommended  the  Company  to
continue the trial as planned.

F-8

April 2020:

•

The U.S. Food and Drug Administration (FDA) has granted the Company Fast Track Designation for the development of eryaspase as a second-
line treatment of patients with metastatic pancreatic cancer.

May 2020:

•

The Company announced it will be part of EVIDENCE, a public-private consortium supported by the European Union in the framework of the EU
Horizon 2020 program. The EVIDENCE consortium, consisting of leading experts in the field of red blood cell research, will explore how red
blood cells are influenced by their extra-cellular environment.

June 2020:

•

•

The  Company  announced  that  the  ongoing  Phase  2  clinical  trial,  sponsored  by  the  Nordic  Society  of  Paediatric  Haematology  and  Oncology
(NOPHO) of eryaspase in second-line acute lymphoblastic leukemia (ALL) patients has reached its target enrollment of 50 patients. Preliminary
findings of the trial suggest that eryaspase achieved the target level and duration of asparaginase activity in these patients. Moreover, the addition
of  eryaspase  to  the  combination  chemotherapy  was  associated  with  an  acceptable  tolerability  profile,  enabling  the  majority  of  these  patients  to
receive their fully intended courses of asparaginase. Recent data have confirmed that discontinuation of asparaginase therapy in ALL patients has
been associated with inferior disease free survival.

The Company signed a financing agreement with Luxembourg-based European High Growth Opportunities Securitization Fund, represented by its
asset manager European High Growth Opportunities Manco SA (entities related to Alpha Blue Ocean), in the form of convertible notes with share
subscription  warrants  attached  (“OCABSA”),  allowing  a  potential  financing  arrangement  of  up  to  a  maximum  of  €60  million,  subject  to  the
regulatory limit of 20% dilution.

November/December 2020:

• As  part  of  the  convertible  notes’  agreement  signed  in  June  2020,  the  Company  issued  three  tranches  of  €3.0  million  each  (60  OCABSA)  on

November 17, 2020, December 7, 2020 and December 22 , respectively.

December 2020:

•

The  Company  announced  positive  results  from  eryaspase  Phase  2  Trial  in  Acute  Lymphoblastic  Leukemia  ("ALL").  The  study  confirms  the
potential  of  eryaspase  as  an  attractive  treatment  option  for  ALL  patients  with  hypersensitivity  to  PEG-asparaginase.  The  Phase  2  NOR-
GRASPALL-2016  trial  evaluated  the  safety  and  pharmacological  profile  of  eryaspase  in  ALL  patients  who  had  previously  experienced
hypersensitivity  reactions  to  pegylated  asparaginase  therapy.  The  trial  was  conducted  by  the  Nordic  Society  of  Pediatric  Hematology  and
Oncology (NOPHO). Primary objectives of the trial were asparaginase enzyme activity and safety. Both endpoints were met.

euros  at  the  closing  exchange  rate  (spot  exchange  rate  at  the  statement  of  financial  position  date)  and  the  statement  of  income  (loss),  statement  of
comprehensive income (loss) and statement of cash flow of such consolidated entity are translated at the average exchange rate for the period, except if
exchanges rates fluctuate significantly. The resulting translation adjustment is included in other comprehensive income (loss) as a cumulative translation
adjustment.

Foreign  currency  transactions  are  converted  to  functional  currency  at  the  exchange  rate  applicable  on  the  transaction  date.  At  the  closing  date,  foreign
currency monetary assets and liabilities are converted at the exchange rate prevailing on that date. The resulting exchange gains or losses are recorded in
the consolidated statement of income (loss) in “Financial income (loss)”.

The loan in U.S. dollars from the Parent Company to ERYTECH Pharma, Inc. was considered as part of the net investment in a foreign operation until the
end of the third quarter of 2019, when the loan was partly converted into capital and partly restructured as a medium term loan. As a result of this financial
restructuring, the loan is no longer qualified as an investment in a foreign operation. Exchange rate differences are recognized in the consolidated statement
of income (loss) since October 1, 2019.

2.5 Use of estimates and judgments

Preparation of the consolidated financial statements in accordance with the rules prescribed by the IFRS requires the use of estimates and the formulation
of assumptions having an impact on the financial statements. These estimates can be revised where the

F-12

circumstances  on  which  they  are  based  change.  The  actual  results  may  therefore  differ  from  the  estimates  initially  formulated.  The  Company  has  not
identified  any  environmental  risks  or  risks  related  to  the  COVID-19  pandemic  that  would  require  significant  new  estimates  or  judgments.  The  use  of
estimates and judgment relate primarily to the measurement of:

•

•

•

•

the share-based payments in accordance with IFRS 2 (see note 3.3.3);

the fair value of the convertible notes' agreement and its classification in accordance with IFRS 9 and IAS 32 (see note 4.9.1);

the hospital costs accrual (see note 4.11).

the recognition of right of use assets and liabilities for leases with a term of more than 12 months according to IFRS 16 (see note 4.2).

2.6 Presentation of the statement of income (loss) & statement of financial position

The  Company  presents  its  statement  of  income  (loss)  by  function.  As  of  today,  the  main  activity  of  the  Company  is  the  research  and  development.
Consequently, only “research and development expenses” and “general administrative expenses” functions are considered to be representative. The detail
of the expenses by nature is disclosed in note 3.2.

In  the  statement  of  financial  position  certain  immaterial  amounts  in  prior  year  have  been  reclassified  to  conform  to  the  current  year  presentation  (other
current financial assets merged with other current assets).

2.7 Presentation of the statement of cash flows

The  consolidated  statements  of  cash  flows  are  prepared  using  the  indirect  method  and  separately  present  the  cash  flows  associated  with  operating,
investing, and financing activities.

2.8 Segment reporting

In accordance with IFRS 8 Operating Segments ("IFRS 8") , reporting by operating segment is derived from the internal organization of the Company’s
activities; it reflects management’s viewpoint and is established based on internal reporting used by the chief operating decision maker (the Chief Executive
Officer) to allocate resources and to assess performance.

Information per business segment

The  Company  operates  in  a  single  operating  segment:  the  conducting  of  research  and  development  of  innovative  red  blood  cell-based  therapeutics  for
cancer and orphan diseases in order to market them in the future.

February 2022: Impact of the Conflict in Ukraine on Our Business

F-13

Beginning on February 24, 2022, Russia significantly intensified its military operations in Ukraine.

In  response,  the  United  States  and  certain  other  countries  have  imposed  significant  sanctions  and  export  controls  against  Russia,  Belarus  and  certain
individuals and entities connected to Russian or Belarusian political, business, and financial organizations, and the U.S. and certain other countries could
impose further sanctions, trade restrictions, and other retaliatory actions should the conflict continue or worsen.

To  date,  we  have  not  experienced  any  material  impact  on  our  business,  operations  and  clinical  development  timelines  and  plans.  However,  we  cannot
predict the specific extent, duration, or impact that the conflict in Ukraine and the related sanctions and export controls will have on our financial condition
and operations.

We are closely monitoring developments in the current context and will take appropriate measures as necessary. The war in Ukraine did not impact our
financial results for the year ended on December 31, 2021. Our business does not conduct any trial in Ukraine or Russia and does not have any vendors
located in these regions.

3. NOTES RELATED TO THE CONSOLIDATED STATEMENT OF INCOME (LOSS)

3.1 Operating income

Accounting policies

Research tax credit

The research tax credit (Crédit d’Impôt Recherche or “CIR”) (the “Research Tax Credit”) is granted to companies by the French tax authorities in order to
encourage them to conduct technical and scientific research. Companies that prove that they have expenditures that meet the required criteria (research
expenditures located in France or, since January 1, 2005, within the European Union or in another State that is a party to the Agreement on the European
Economic Area that has concluded a tax treaty with France that contains an administrative assistance clause) receive a tax credit that (a) can be used for the
payment  of  the  corporate  tax  due  for  the  fiscal  year  in  which  the  expenditures  were  made  and  the  next  three  fiscal  years,  or,  (b)  as  applicable,  can  be
reimbursed in cash. The expenses taken into account for the calculation of the Research Tax Credit involve only research expenses.

The Company benefits from the Research Tax Credit since its inception.

The CIR is presented under operating income as it meets the definition of government grant as defined in IAS 20 Accounting for Government Grants and
Disclosure of Government Assistance (“IAS 20”).

Subsidies

Subsidies received that are not repayable by the Company are recognized as operating income where there exists reasonable assurance that the Company
will comply with the conditions attached to the subsidies and the subsidies will be received.

Subsidies that are upfront payments are presented as deferred revenue and recognized ratably through income over the duration of the research program to
which the subsidy relates.

A  public  subsidy  that  is  to  be  received  either  as  compensation  for  expenses  or  for  losses  already  incurred,  or  for  immediate  financial  support  of  the
Company without associated future costs, is recognized as operating income when there exists reasonable assurance that the subsidies will be received.

Revenues from licenses or other contracts

For each of its partnership agreements, the Company determines if it acts as a principal or as an agent in accordance with IFRS 15 Revenue from contracts
with customers (“IFRS 15").

Partnership with Orphan Europe NOPHO clinical trial

Within the context of this agreement, Orphan Europe agreed to finance the NOPHO study for a total amount of €600 thousand. This revenue is recognized
in “other income” in the statement of income (loss).

License agreement with SQZ Biotechnologies (“SQZ”)

Under the terms of the agreement, the Company has granted to SQZ Biotechnologies an exclusive worldwide license to develop antigen specific immune
modulating therapies employing red blood cell-based approaches. In accordance with IFRS 15, this agreement grants to SQZ Biotechnologies a right to use
the underlying intellectual property ("static license"). Consequently, the income linked to the upfront payment ($1.0 million) was recognized in June 2019
when SQZ Biotechnologies could begin to use the licensed intellectual property.

The Company does not generate any revenue from the sale of its products considering its stage of development.

3.3.3.

Share-based payments (IFRS 2)

Accounting policies

The Company has applied IFRS 2 Share-based payment (“IFRS 2”)  to  all  equity  instruments  e.g.  free  shares  (“AGA”), stock options (“SO”),  share
subscription  warrants  (“BSA”)  and  founder  subscription  warrants  (“BSPCE”)  granted  since  inception  to  its  employees,  members  of  the  Board  of
Directors or other individuals. Pursuant to IFRS 2, the cost of the remuneration granted with equity instruments is recognized as an expense in exchange
for an increase in the shareholders’ equity for the vesting period during which the rights to be enjoyed from the equity instruments are acquired. As such,
changes in value subsequent to the grant date have no effect on this initial measurement.

Fair value is estimated using the Black & Scholes valuation model (for BSA, SO and BSPCE valuation) and Monte-Carlo valuation model (for AGA
valuation). These models allow the Company to take into account the characteristics of the plan (exercise price, vesting period), the market data at the
grant date (volatility, expected dividends, repo margin), possible performance conditions attached to warrants and recipient behavior assumptions.

The Company has no legal or constructive obligation to repurchase or settle any of these equity instruments in cash.
