You should refer to the section of this Annual Report titled “Item 3.D – Risk Factors” for a discussion of important factors that may cause our actual results
to differ materially from those expressed or implied by our forward-looking statements. As a result of these factors, we cannot assure you that the forward-
looking statements in this Annual Report will prove to be accurate. Furthermore, if our forward-looking statements prove to be inaccurate, the inaccuracy
may be material. In light of the significant uncertainties in these forward-looking statements, you should not regard these statements as a representation or
warranty by us or any other person that we will achieve our objectives and plans in any specified time frame or at all. We undertake no obligation to publicly
update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. The Private Securities
Litigation Reform Act of 1995 and Section 27A of the Securities Act do not protect any forward-looking statements that we make in connection with this
Annual Report.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon
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, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of,
all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

You should read this Annual Report and the documents that we reference in this Annual Report and have filed as exhibits to this Annual Report completely
and with the understanding that our actual future results, levels of activity, performance and events and circumstances may be materially different from what
we expect. We qualify all of our forward-looking statements by these cautionary 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.”

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.

Risks Related to the Development and Commercialization of Lumoxiti and Our Product Candidates

Biopharmaceutical  development  involves  a  high  degree  of  uncertainty  and  most  of  our  product  candidates  are  in  early  stages  of  development,  which
makes it difficult to evaluate our current business and future prospects and may increase the risk of your investment.

We are a biopharmaceutical company with one commercial product, Lumoxiti, which we acquired in October 2018 from AstraZeneca and which we have not
yet begun to commercialize on our own. The rest of our portfolio consists of product candidates, some of which we are co-developing, in the early stages of
clinical  development  and  preclinical  programs.  Although  we  have  generated  limited  revenue  from  product  sales  from  our  only  product  approved  by
regulatory authorities, Lumoxiti, we do not expect to have any other significant product sales or related revenue unless our additional product candidates or
any  future  product  candidates  are  approved  for  sale  and  successfully  commercialized.  Accordingly,  our  ability  to  predict  our  future  operating  results  or
business prospects is more limited than if we had a longer history of approved products on the market or later-stage clinical product candidates. Although
Lumoxiti  has  been  approved  by  the  U.S.  Food  and  Drug  Administration,  or  the  FDA,  it  has  only  been  marketed  for  a  short  period  of  time  and,  to  date,
AstraZeneca has been responsible for its commercialization.

A  key  element  of  our  strategy  is  to  mature  and  expand  our  portfolio  of  proprietary  and  partnered  product  candidates  to  address  unmet  medical  needs  in
immuno-oncology. Although our research and development efforts to date have resulted in a pipeline of product candidates, all of our product candidates
require  additional  development,  regulatory  review  and  approvals,  substantial  investment,  access  to  sufficient  commercial  manufacturing  capacity  and
significant  marketing  efforts  before  they  can  be  commercialized  and  before  we  can  generate  any  revenue  from  product  sales  or  royalties.  If  we  or  our
collaboration  partners  are  unable  to  successfully  develop  and  market  these  product  candidates,  our  business,  prospects,  financial  condition  and  results  of
operations may be adversely affected.

Aside from our acquisition of Lumoxiti, our operations to date have been limited to developing our product candidates and undertaking preclinical studies
and  clinical  trials  of  our  product  candidates,  including  monalizumab,  through  our  partnership  with  AstraZeneca,  lacutamab  and  avdoralimab,  our  most
advanced  product  candidates.  The  success  in  development  of  our  current  and  future  product  candidates  by  us  or  our  collaborators  will  depend  on  many
factors, including:

11

 
 
 
 
 
 
 
 
 
 
·

·

·

·

·

·

·

·

obtaining positive results in clinical trials including by demonstrating efficacy, safety and durability of effect of such product candidates;

completing preclinical studies and receiving regulatory approvals or clearance for conducting clinical trials for our preclinical programs;

receiving and maintaining approvals for commercialization of such product candidates from regulatory authorities;

manufacturing or overseeing the manufacturing of our product candidates in acceptable quantities and at an acceptable cost;

negotiating favorable terms in any collaboration, licensing or other arrangements into which we may enter, and performing our obligations pursuant to
such arrangements;

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

avoiding and defending against third-party interference, infringement or other intellectual property claims; and

maintaining  and  growing  an  organization  of  scientists,  medical  professionals,  marketing,  distribution  and  sales  personnel  and  executives  who  can
develop our product candidates and commercialize any approved products.

In  addition,  if  we  are  unable  to  reduce  our  dependence  on  Lumoxiti  and  our  current  clinical  and  preclinical  product  candidates,  either  by  in-licensing  or
acquiring new product candidates, developing our other product candidates or discovering new product candidates, we may be similarly adversely affected.

We will become fully responsible for the commercialization of Lumoxiti by end of 2020 but we are in the process of building our sales, marketing or
commercial product distribution organization and have no experience in marketing or managing the manufacturing of products.

We are a biopharmaceutical company with one commercial product, Lumoxiti, which we recently acquired and have not yet begun to commercialize on our
own.  Even  though  we  began  to  transition  certain  activities  relating  to  the  commercialization  and  manufacturing  of  Lumoxiti  in  the  United  States  in  the
second half of 2019, AstraZeneca is still responsible for most of those aspects. We plan on being fully responsible for its commercialization by end of 2020
and for its manufacturing at a later date. We are in the process of building our sales, marketing or commercial product distribution capabilities and have no
experience in managing the manufacturing of or marketing products. Developing our in-house marketing and sales capabilities and infrastructure requires
significant  expenses,  management  resources  and  time.  If  we  are  able  to  achieve  this  goal,  we  will  compete  with  other  pharmaceutical  and  biotechnology
companies to recruit, hire, train and retain marketing, sales and distribution personnel.

If we are unable or decide not to establish or expand internal sales, marketing and commercial distribution capabilities for Lumoxiti or any of the products we
may develop, we will likely pursue contractual arrangements for the sale, marketing and distribution of such products. However, there can be no assurance
that we will be able to establish or maintain such arrangements, and if we do, we may have little or no control over the sales, marketing and commercial
distribution efforts of such third parties. Any revenue we receive will depend upon the efforts of these third parties, and their efforts may not be successful.
Our  revenue  from  product  sales  may  be  lower  than  if  we  had  commercialized  Lumoxiti  or  any  future  product  candidates  we  may  develop,  if  approved,
ourselves. We will also face competition in our search for third parties to assist us with the sales, marketing and distribution efforts of Lumoxiti or any of our
product candidates that receive regulatory approval.

There can be no assurance that we will be able to develop in-house sales and commercial distribution capabilities or establish or maintain relationships with
third-party partners to successfully commercialize any product in the United States, Europe or elsewhere and, as a result, we may not be able to generate
product revenue.

If  we  are  unable  to  establish  sales,  marketing  and  distribution  capabilities  for  Lumoxiti  on  a  timely  basis,  we  may  not  be  successful  in  commercializing
Lumoxiti.

We have a limited sales, marketing or distribution infrastructure and have no experience in the sale, marketing or distribution of pharmaceutical products. To
achieve commercial success for any approved product, including our approved product, Lumoxiti, we must either develop a sales and marketing organization
or outsource these functions to third parties. Lumoxiti has only been commercially available for a short period of time and, to date, the responsibilities of
commercialization have been handled by AstraZeneca. We plan to use a combination of focused in-house sales and marketing capabilities and third-party
collaboration, licensing and distribution arrangements to sell any of our products that receive marketing approval.

The  development  of  sales,  marketing  and  distribution  capabilities  will  require  substantial  resources,  will  be  time-consuming,  could  delay  the  continued
commercialization of Lumoxiti and could delay any other potential product launch. If the commercial launch of a product for which we recruit a sales force
and establish marketing and distribution capabilities is delayed or does not occur for any reason, we could have prematurely or unnecessarily incurred these
commercialization  costs.  This  may  be  costly,  and  our  investment  could  be  lost  if  we  cannot  retain  or  reposition  our  sales  and  marketing  personnel.  In
addition, we may not be able to hire or retain a sales force that is sufficient in size or has adequate expertise in the medical markets that we plan to target. If
we are unable to establish or retain a sales force and marketing and distribution capabilities, our operating results may be adversely affected. If a potential
partner has development or commercialization expertise that we believe is particularly relevant to one of our product candidates, we may seek to collaborate
with that potential partner even if we believe we could otherwise develop and commercialize the product independently.

The scientific evidence to support the feasibility of developing product candidates is both preliminary and limited.

Our innovative approach to immuno-oncology aims to activate both the innate and adaptive immune systems against abnormal or cancerous cells and restore
the  body’s  ability  to  disrupt  their  proliferation,  potentially  leading  to  durable  responses  in  patients.  This  approach  is  focused  on  developing  checkpoint
inhibitors,  tumor-targeting  antibodies  and  antibodies  that  affect  the  tumor  microenvironment,  and  several  of  our  product  candidates  rely  on  novel
mechanisms of action for which we have limited scientific evidence and preclinical and clinical data.

13

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We may not ultimately be able to provide the FDA, European Medicines Agency, or EMA, or other regulatory authorities with substantial clinical evidence
to support a claim of efficacy and durability of response to enable the applicable regulators to approve our product candidates for any indication. This may
occur because later clinical trials fail to reproduce favorable data obtained in earlier clinical trials, because the applicable regulator disagrees with how we
interpret the data from these clinical trials or because the applicable regulator does not accept these therapeutic effects as valid endpoints in pivotal clinical
trials that are sufficient to grant marketing approval. Additionally, because product candidates in later stages of clinical trials may fail to show the desired
safety and efficacy traits despite having progressed through preclinical studies and earlier clinical trials our collaborators in earlier stages of clinical trials
may  eventually  choose  to  discontinue  later  stage  trials.  For  example,  following  initial  promising  results  assessing  the  safety  and  efficacy  of  our  product
candidate lirilumab for the treatment of various cancer indications, our collaborator decided not to continue development after receiving Phase II clinical trial
data.

In  addition  to  the  safety  and  efficacy  traits  of  any  product  candidate,  clinical  trial  failures  may  result  from  a  multitude  of  factors  including  flaws  in  trial
design,  dose  selection,  placebo  effect  and  patient  enrollment  criteria.  A  number  of  companies  in  the  pharmaceutical  industry  have  suffered  significant
setbacks in advanced clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier trials, and it is possible that
we will as well. Based upon negative or inconclusive results, we or our collaborators may decide, or regulators may require us, to conduct additional clinical
trials or preclinical studies. In addition, data obtained from trials and studies are susceptible to varying interpretations, and regulators may not interpret our
data as favorably as we do, which may delay, limit or prevent regulatory approval.

We  will  also  need  to  demonstrate  that  our  product  candidates  are  safe  and  well  tolerated.  We  do  not  have  significant  data  on  possible  harmful  long-term
effects of our product candidates and do not expect to have this data in the near future. As a result, our ability to generate clinical safety and efficacy data
sufficient to support submission of a marketing application or commercialization of our product candidates is uncertain and is subject to significant risk.

We  intend  to  develop  monalizumab,  avdoralimab  (IPH5401)  and  other  product  candidates  in  combination  with  other  therapies,  which  exposes  us  to
additional risks.

We are currently developing monalizumab and avdoralimab, and may develop other product candidates, in combination with one or more currently approved
cancer therapies. Specifically, with AstraZeneca, we are currently evaluating monalizumab in an ongoing open-label Phase Ib/II trial in combination with
cetuximab, an epidermal growth factor receptor, or EGFR, inhibitor, and also in a triplet setting with cetuximab and durvalumab, an anti-PD-L1 immune
checkpoint inhibitor. AstraZeneca is also currently evaluating monalizumab in ongoing Phase I and II trials in combination with durvalumab Additionally, we
are currently conducting a Phase I/II clinical trial of avdoralimab in combination with durvalumab, initially in patients with select advanced solid tumors.
Patients may not be able to tolerate our product candidates in combination with other therapies, and preliminary clinical results indicate that monalizumab,
for  example,  has  no  meaningful  clinical  activity  as  a  monotherapy.  Even  if  any  product  candidate  we  develop  were  to  receive  marketing  approval  or  be
commercialized for use in combination with other existing therapies, we would continue to be subject to the risks that the FDA, EMA or other comparable
foreign regulatory authorities could revoke approval of the therapy used in combination with our product candidate or that safety, efficacy, manufacturing or
supply issues could arise with these existing therapies. Combination therapies are commonly used for the treatment of cancer, and we would be subject to
similar risks if we develop any of our product candidates for use in combination with other therapies or for indications other than cancer. This could result in
our own products, if approved, being removed from the market or being less successful commercially.

14

 
 
 
 
 
 
 
 
We may also evaluate monalizumab, avdoralimab or any other future product candidates in combination with one or more other cancer therapies that have
not yet been approved for marketing by the FDA, EMA or comparable foreign regulatory authorities. We will not be able to market and sell monalizumab,
avdoralimab or any other product candidate we develop in combination with any such unapproved cancer therapies that do not ultimately obtain marketing
approval.

If the FDA, EMA or other comparable foreign regulatory authorities do not approve, revoke their approval of, or if safety, efficacy, manufacturing or supply
issues arise with, the products or product candidates we choose to evaluate in combination with monalizumab, avdoralimab or any other product candidate
we develop, we may be unable to obtain approval of or market monalizumab, avdoralimab or any other such product candidate we develop.

We and our collaborators rely on third parties to conduct some of our preclinical studies and clinical trials and perform other clinical development tasks.
If these third parties do not successfully carry out their contractual duties, meet expected deadlines or comply with regulatory requirements, it may not be
possible to obtain regulatory approval for, or commercialize, our product candidates and our business could be substantially harmed.

We have relied upon and plan to continue to rely upon third parties to conduct clinical trials of our product candidates or product candidates that we have
licensed to them. For example, under our license and collaboration agreements with AstraZeneca, AstraZeneca is responsible for a number of clinical trials
relating to monalizumab and IPH5201, which are subject to such agreements. In addition, we and our collaborators are responsible for and are supporting
several clinical trials that are sponsored by academic or research institutions, known as investigator-sponsored trials. By definition, the financing, design and
conduct of an investigator-sponsored trial are the sole responsibility of the sponsor, and we or our collaborators, as applicable, have limited control over these
aspects  of  these  clinical  trials,  or  the  timing  and  reporting  of  the  data  from  these  trials.  We  and  our  collaborators  also  depend  on  independent  clinical
investigators and Contract Research Organizations, or CROs, to conduct clinical trials. CROs may also assist in the collection and analysis of data. There are
a limited number of CROs that have the expertise to run clinical trials of our product candidates. Identifying, qualifying and managing performance of third-
party service providers can be difficult and time consuming and can cause delays in our development programs. These investigators and CROs are not our
employees and we are not able to control, other than by contract, the amount of resources, including the amount of time, that they devote to our product
candidates and clinical trials. If the investigators sponsoring trials of our product candidates, independent investigators participating in clinical trials that we
or our collaborators are sponsoring or CROs fail to devote sufficient resources to our clinical trials and development of our product candidates or product
candidates we have licensed to others, or if their performance is substandard, it may delay or compromise the prospects for approval and commercialization
of any product candidates that we or our collaborators develop. In addition, the use of third-party service providers requires us to disclose our proprietary
information to these parties, which could increase the risk that this information will be misappropriated, and we may not be able to obtain adequate remedies
for such disclosure or misappropriation. Further, the FDA, EMA and other regulatory authorities require that we comply with standards, commonly referred
to as Good Clinical Practice, or GCP, and other local legal requirements, including data privacy regulations, for conducting, recording and reporting clinical
trials to assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of clinical trial subjects are protected. If
clinical investigators or CROs fail to meet their obligations to us or comply with GCP procedures or other applicable legal requirements, the data generated
in these trials may be deemed unreliable and the FDA, EMA or comparable foreign regulatory authorities may require us to perform additional trials before
approving our marketing applications. We cannot assure that upon inspection by a given regulatory authority, such regulatory authority will determine that all
of our clinical trials comply with GCP regulations.

15

 
 
 
 
 
 
 
In addition, our clinical trials must be conducted with product produced under current Good Manufacturing Practice, or cGMP, regulations. Our failure to
comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process. If clinical investigators or CROs do
not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the
data they obtain is compromised due to the failure to adhere to our protocol or regulatory requirements, or for other reasons, our clinical trials or those of our
collaborators  may  be  extended,  delayed  or  terminated,  and  we  or  our  collaborators  may  not  be  able  to  obtain  regulatory  approval  for  or  successfully
commercialize our product candidates. As a result, our results of operations and the commercial prospects for our product candidates would be harmed, our
costs could increase and our ability to generate revenue could be delayed.

We are heavily dependent on the success of our current clinical-stage product candidates and we cannot be certain that we or our collaborators will be
able to obtain regulatory approval for, or successfully commercialize, these product candidates.

Our  business  and  future  success  depend  on  receiving  regulatory  approval  for,  and  the  commercial  success  of,  our  proprietary  and  partnered  product
candidates. We have agreements with AstraZeneca with respect to the advanced development, clinical trial collaboration and potential future registration and
marketing of several of our product candidates, including monalizumab and IPH5201, and with Sanofi for the research and development of IPH61. Our near-
term prospects depend heavily on AstraZeneca’s successful clinical development and commercialization of monalizumab as well as the successful clinical
development of our other product candidates. The clinical success of these product candidates will depend on a number of factors, including the ability and
willingness  of  AstraZeneca  and  our  other  collaborators  to  complete  ongoing  clinical  trials  for  monalizumab,  our  ability  to  complete  the  clinical  trials  for
which we are responsible, and the safety, tolerability and efficacy of our product candidates.

16

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We may not be successful in our efforts to develop additional products that receive regulatory approval and are successfully commercialized.

Other than our commercial product, Lumoxiti, our pipeline consists of various product candidates at different phases of preclinical and clinical development.
The development of a product candidate is a long, costly and uncertain process, aimed at demonstrating the therapeutic benefit of a product candidate that
competes with existing products or those being developed. There is no guarantee that we or our collaborators will be able to demonstrate a sufficient degree
of clinical efficacy or safety of one or more of our proprietary or licensed product candidates in order to gain regulatory approval or to become commercially
viable. The degree of uncertainty associated with clinical development and the risks associated with developing new product candidates may make it difficult
to evaluate our current business and our future prospects.

We intend to continue to develop our product candidates that are currently in clinical trials, including monalizumab, lacutamab, avdoralimab and IPH5201.
Monalizumab is currently being investigated in multiple Phase I and Phase II clinical trials under a co-development agreement with AstraZeneca. Lacutamab
is currently being investigated in an open-label, multi-cohort Phase II clinical trial. Avdoralimab is currently being evaluated in Phase I and Phase II clinical
trials. IPH5201 is currently being investigated in an open-label Phase I clinical trial sponsored by AstraZeneca. While we believe that we will eventually
have the in-house capabilities to complete the development of monalizumab, lacutamab, avdoralimab and IPH5201, we have not yet completed the clinical
trials for these or other product candidates, and there can be no assurance that these or other product candidates will gain regulatory approval or become
commercially viable.

Delays  in  the  preclinical  development  of  a  product  candidate  could  lead  to  delays  in  initiating  its  clinical  development.  A  failure  in  the  preclinical
development of a product candidate could lead to abandoning its development. Further delays or failures at the various clinical stages for a given indication
could result in delay or halt the development of the product candidate in such indication or in other indications. Moreover, disappointing results during the
initial  phases  of  development  are  often  not  a  sufficient  basis  for  deciding  whether  or  not  to  continue  a  project.  At  these  early  stages,  sample  sizes,  the
duration of studies and the parameters examined may not be sufficient to enable a definitive conclusion to be drawn, in which case further investigations are
required. Conversely, promising results during the initial phases, and even after advanced clinical trials have been conducted, do not guarantee that a product
candidate or an approved drug, such as Lumoxiti, will be successfully commercialized and marketed.

The risks related to the failure of a product candidate’s development are highly related to the stage of maturity of the product candidate. Given the relatively
early stage of the product candidates in our pipeline, there is a substantial risk that some or all of our product candidates will not obtain regulatory approval
or be commercialized, which would have an adverse impact on our business, prospects, financial condition and results of operations.

We may not be successful in our efforts to identify, discover or develop additional product candidates.

We are seeking to develop a broad and innovative pipeline of product candidates in addition to monalizumab, lacutamab, avdoralimab and IPH5201. We may
not be successful in identifying additional product candidates for clinical development for a number of reasons. For example, our research methodology may
be unsuccessful in identifying potential product candidates or the potential product candidates we identify may have harmful side effects, lack of efficacy or
other characteristics that make them unmarketable or unlikely to receive regulatory approval.

17

 
 
 
 
 
 
 
 
 
 
Research programs to pursue the development of our product candidates for additional indications and to identify new product candidates and disease targets
require  substantial  technical,  financial  and  human  resources.  Our  research  programs  may  initially  show  promise  in  identifying  potential  indications  or
product candidates, yet fail to yield results for clinical development for a number of reasons, including:

·

·

·

the research methodology used may not be successful in identifying potential indications or product candidates;

potential product candidates may, after further study, be shown to have harmful adverse effects or other characteristics that indicate they are unlikely
to be effective drugs; or

it may take greater human and financial resources to identify additional therapeutic opportunities for our product candidates or to develop suitable
potential product candidates through internal research programs than we will possess, thereby limiting our ability to diversify and expand our product
portfolio.

Accordingly, there can be no assurance that we will ever be able to identify additional indications for our product candidates or to identify and develop new
product candidates through internal research programs. We may focus our efforts and resources on potential product candidates or other potential programs
that ultimately prove to be unsuccessful.

We may encounter substantial delays in our clinical trials, or may be unable to conduct our clinical trials on the timelines we expect.

Clinical  testing  is  expensive,  time  consuming,  and  subject  to  uncertainty.  We  cannot  guarantee  that  any  clinical  trials  will  be  conducted  as  planned  or
completed on schedule, if at all. A failure of one or more clinical trials can occur at any stage of testing, and our future clinical studies may not be successful.
Events that may prevent successful or timely completion of clinical development include:

·

·

·

·

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

delays or failure in reaching a consensus with regulatory agencies on clinical trial design;

delays in reaching agreement on acceptable terms with prospective CROs and investigational sites, the terms of which can be subject to extensive
negotiation and may vary significantly among different CROs and investigational sites;

imposition of a temporary or permanent clinical hold by regulatory agencies, including as a result of a new safety finding that presents unreasonable
risk to clinical trial participants, a negative finding from an inspection of our clinical trial operations or investigational sites, developments in trials
conducted by competitors for related technology that raise regulators’ concerns about risk to patients of the technology broadly or if a regulatory body
finds that the investigational protocol or plan is clearly deficient to meet its stated objectives. For example, in November 2019, our TELLOMAK trial
was  put  on  full  or  partial  holds  in  a  number  of  countries.  See  “Item  4.B–Business  Overview—Lacutamab,  A  Tumor  Targeting  Anti-KIR3DL2
Antibody—Clinical Development of Lacutamab—Phase II Clinical Trial (TELLOMAK);”

delays in recruiting suitable patients to participate in our clinical trials;

difficulty collaborating with patient groups and investigators;

failure by us, our CROs or other third parties, including our collaborators, to adhere to clinical trial requirements;

delays in having patients complete participation in a clinical trial or return for post-treatment follow-up;

patients withdrawing from a clinical trial;

occurrence of adverse events associated with a product candidate that are viewed to outweigh its potential benefits;

changes in regulatory requirements and guidance that require amending or submitting new clinical trial protocols;

regulatory feedback requiring us to amend the protocols of ongoing clinical trials in response to safety considerations, as we have previously been
required to;

changes in the standard of care on which a clinical development plan was based, which may require new or additional clinical trials;

the cost of clinical trials of our product candidates being greater than we anticipate;

clinical trials of our product candidates producing negative or inconclusive results, which may result in our deciding, or regulators requiring us, to
conduct additional clinical trials or abandon product development programs;

transfer of manufacturing processes to larger-scale facilities operated by either a contract manufacturing organization, or CMO, or by us, and delays or
failure by our CMOs or us to make any necessary changes to such manufacturing process; and

batch recalls, recalls of manufactured product candidates or delays in manufacturing, testing, releasing, validating, or importing or exporting sufficient
stable quantities of our product candidates for use in clinical trials or the inability to do any of the foregoing.

Any inability to successfully complete preclinical and clinical development could result in additional costs to us or impair our ability to generate revenue. In
addition, if we make manufacturing or formulation changes to our product candidates, we may be required to or we may elect to conduct additional studies to
bridge  our  modified  product  candidates  to  earlier  versions.  Clinical  study  delays  could  also  shorten  any  periods  during  which  our  products  have  patent
protection  and  may  allow  our  competitors  to  bring  products  to  market  before  we  do,  which  could  impair  our  ability  to  successfully  commercialize  our
product candidates and may harm our business and results of operations.

Lumoxiti or our product candidates in development may cause undesirable side effects or have other properties that could halt or delay their clinical
development, prevent their regulatory approval, limit their commercialization or result in other negative consequences.

Use of our approved product, Lumoxiti, or our product candidates in development could be associated with side effects or adverse events which can vary in
severity  and  in  frequency.  Undesirable  side  effects  or  unacceptable  toxicities  caused  by  our  products  or  product  candidates  could  cause  us  or  regulatory
authorities to interrupt, delay, or halt clinical trials. The FDA or European regulatory authorities could delay or deny approval of our product candidates for
any or all targeted indications and negative side effects could result in a more restrictive label for any drug that is approved. Side effects such as toxicity or
other  safety  issues  associated  with  the  use  of  our  product  candidates  could  also  require  us  or  our  collaborators  to  perform  additional  studies  or  halt
development of product candidates or sale of approved products.

Treatment-related side effects could also affect patient recruitment or the ability of enrolled subjects to complete the trial, or could result in potential product
liability claims. In addition, these side effects may not be appropriately or timely recognized or managed by the treating medical staff, as toxicities resulting
from  immunotherapy  are  not  normally  encountered  in  the  general  patient  population  and  by  medical  personnel.  Inadequate  training  in  recognizing  or
managing the potential side effects of our product candidates or our approved product, Lumoxiti, could result in adverse effects to patients, including death.
Any of these occurrences may have an adverse impact on our business, prospects, financial condition and results of operations.

We face substantial competition from companies with significantly greater resources and experience.

The  biotechnology  and  pharmaceutical  market,  and  notably  the  immuno-oncology  field,  is  characterized  by  rapidly  advancing  technologies,  products
protected by intellectual property rights and intense competition and is subject to significant and rapid change as researchers learn more about diseases and
develop new technologies and treatments. We face potential competition from many different sources, including major pharmaceutical companies, specialty
pharmaceutical  and  biotechnology  companies,  academic  institutions  and  governmental  agencies  and  public  and  private  research  institutions.  Any  product
candidates that we or our collaborators successfully develop will compete with existing therapies and new therapies that may become available in the future.
If competing products are marketed before ours, or at lower prices, or cover a wider therapeutic spectrum, or if they prove to be more effective or better
tolerated, our business, prospects, financial condition and results of operations could be affected.

Many of our competitors who are developing immuno-oncology and anti-cancer therapies have considerably greater resources and experience in research,
access  to  patients  for  clinical  trials,  drug  development,  finance,  manufacturing,  marketing,  technology  and  personnel  than  we  do.  In  particular,  large
pharmaceutical companies have substantially more experience than we do in conducting clinical trials and obtaining regulatory authorizations. Mergers and
acquisitions in the pharmaceutical, biotechnology and diagnostic 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 are also likely to compete with us to recruit and retain scientific and management personnel, acquire rights for
promising  product  candidates  and  other  complementary  technologies,  establish  clinical  trial  sites  and  patient  registration  for  clinical  trials  and  acquire
technologies  complementary  to,  or  necessary  for,  our  programs,  as  well  as  to  enter  into  collaborations  with  partners  who  have  access  to  innovative
technologies. If we cannot successfully compete with new or existing products, our marketing and sales will suffer and we may never be profitable. Should
any of these risks materialize, our business, prospects, financial condition and results of operations may be adversely affected.

20

 
 
 
 
 
 
 
 
 
We cannot guarantee that our product candidates or our approved product, Lumoxiti, will:

·

·

·

·

obtain regulatory authorizations or become commercially available before those of our competitors;

remain competitive in the face of other products developed by our competitors, which may prove to be safer, are more effective, have fewer or less
severe side effects, are more convenient, have a broader label, have more robust intellectual property protection or are less expensive;

remain competitive in the face of products of competitors that are more efficient in their manufacturing or more effective in their marketing; and

not become obsolete or unprofitable due to technological progress or other therapies developed by our competitors.

In addition, while our approved product and any future product candidates that are approved may compete with many existing drugs or other therapies, to the
extent they are solely used in combination with these therapies, our product candidates will not be competitive with such therapies but any sales of such
products  could  be  limited  to  sales  of  the  combination  therapy.  In  this  case,  we  would  be  exposed  to  the  same  competitive  risks  as  the  product  used  in
combination with our product, such as a product that is marketed before the combination therapy, has lower prices, covers a wider therapeutic spectrum or
proves to be more effective or better tolerated. For additional information regarding competition to our business see “Business—Competition.”

We depend on enrollment of patients in our clinical trials for our product candidates.

Successful and timely completion of clinical trials will require that we or our subcontractors enroll a sufficient number of suitable patients. Clinical trials may
be  subject  to  delays  as  a  result  of  patient  enrollment  taking  longer  than  anticipated  or  patient  withdrawal.  Patient  enrollment  depends  on  many  factors,
including the size and nature of the patient population, which is typically limited for rare or orphan diseases making the enrollment more difficult, eligibility
criteria for the trial, the proximity of patients to clinical sites, the design of the clinical protocol, the availability of competing clinical trials, the availability of
new drugs approved for the indication the clinical trial is investigating, and clinicians’ and patients’ perceptions as to the potential advantages of the drug
being studied in relation to other available therapies. For example, we are developing lacutamab for the treatment of cutaneous T-cell lymphoma, or CTCL.
CTCL is an orphan disease, which means that the potential patient population is limited. In addition, there are several other product candidates potentially in
development for the indications for which we are developing product candidates, and we may compete for patients with the sponsors of trials for those drugs.
These  factors  may  make  it  difficult  for  us  to  enroll  enough  patients  to  complete  our  clinical  trials  in  a  timely  and  cost-effective  manner.  Delays  in  the
completion of any clinical trial of any of our product candidates will increase our costs, slow down our product candidate development and approval process
and delay or potentially jeopardize our ability to commence product sales and generate revenue. In addition, some of the factors that cause, or lead to, a delay
in the commencement or completion of clinical trials may also ultimately lead to the inability to obtain regulatory approval of our product candidates.

21

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

Successful sales of Lumoxiti and our product candidates, if approved, will depend, in part, on the availability of adequate coverage and reimbursement from
government  authorities  and  third-party  payors,  such  as  private  health  insurers  and  health  maintenance  organizations.  Patients  who  are  provided  medical
treatment for their conditions generally rely on third-party payors to reimburse all or part of the costs associated with their treatment. Adequate coverage and
reimbursement  from  governmental  healthcare  programs,  such  as  Medicare  and  Medicaid  in  the  United  States  or  the  Social  Security  in  France,  and
commercial payors are critical to new product acceptance.

Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which drugs and treatments they
will cover and the amount of reimbursement. Coverage and reimbursement by a third-party payor may depend upon a number of factors, including the third-
party payor’s determination that use of a product is:

·

·

·

·

·

a covered benefit under its health plan;

safe, effective and medically necessary;

appropriate for the specific patient;

cost-effective; and

neither experimental nor investigational.

Policies for coverage and reimbursement for products vary among third-party payors. No uniform policy of coverage and reimbursement for products exists
among  third-party  payors,  and  third-party  payors  are  increasingly  challenging  the  price,  examining  the  medical  necessity,  and  reviewing  the  cost-
effectiveness of approved drugs and medical services, in addition to questioning their safety and efficacy. As a result, obtaining coverage and reimbursement
approval of a product from a government or other third-party payor is a time-consuming and costly process that could require us or our partners to provide to
each payor supporting scientific, clinical and cost-effectiveness data for the use of our products on a payor-by-payor basis, with no assurance that coverage
and adequate reimbursement will be obtained. 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.  Even  if  we  obtain  coverage  for  a  given
product, the resulting reimbursement payment rates might not be adequate for us to achieve or sustain profitability or may require co-payments that patients
find  unacceptably  high.  Additionally,  third-party  payors  may  not  cover,  or  provide  adequate  reimbursement  for,  long-term  follow-up  evaluations  required
following the use of our product candidates or approved products.

Because  our  product  candidates  and  our  approved  product,  Lumoxiti,  represent  new  approaches  to  the  treatment  of  cancer  and  accordingly,  may  have  a
higher cost than conventional therapies and may require long-term follow-up evaluations, the risk that coverage and reimbursement rates may be inadequate
for  us  to  achieve  profitability  may  be  elevated.  There  are  currently  a  limited  number  of  immunotherapy  products  that  are  designed  to  treat  cancer  on  the
market and, accordingly, there is less experience or precedent for the reimbursement of such treatments by governmental entities or third-party payors.

Government restrictions on pricing and reimbursement and other healthcare cost-containment initiatives may negatively affect our ability to generate
revenues for Lumoxiti and other product candidates for which we obtain regulatory approval.

Government authorities and other third-party payors are developing increasingly sophisticated methods of controlling healthcare costs, including by limiting
coverage and the amount of reimbursement for particular medications. Increasingly, third-party payors are requiring that pharmaceutical and biotechnology
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 the United States, the European Union and other foreign jurisdictions, there have been a number of legislative and regulatory changes to the healthcare
system  that  could  affect  our  or  our  partners’  ability  to  sell  our  products  profitably.  By  way  of  example,  in  the  United  States,  the  Patient  Protection  and
Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, which we collectively refer to as the ACA, was enacted in March
2010 and is having a significant impact on the provision of, and payment for, healthcare in the United States. The ACA was intended to broaden access to
health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new transparency requirements for
the healthcare and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms.

Among the provisions of the ACA of importance to our product candidates are:

·

·

·

an annual, nondeductible fee on any entity that manufactures or imports specified branded prescription drugs and biologic agents, apportioned among
these entities according to their market share in certain government healthcare programs;

an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23.1% and 13.0% of the average
manufacturer price for branded and generic drugs, respectively;

a new Medicare Part D coverage gap discount program, in which manufacturers must now agree to offer 70% point-of-sale discounts off negotiated
prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for a manufacturer’s outpatient drugs to be
covered under Medicare Part D;

23

 
 
 
 
 
 
 
 
 
 
 
·

·

·

·

extension  of  a  manufacturer’s  Medicaid  rebate  liability  to  covered  drugs  dispensed  to  individuals  who  are  enrolled  in  Medicaid  managed  care
organizations;

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

expansion of the entities eligible for discounts under the Public Health Service pharmaceutical pricing program; and

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

There have been judicial and Congressional challenges to certain aspects of the ACA, as well as recent efforts by the Trump administration to repeal and
replace  certain  aspects  of  the  ACA,  and  we  expect  such  challenges  to  continue.  Since  January  2017,  President  Trump  has  signed  two  executive  orders
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 has considered legislation that would repeal or repeal and replace all or part of the ACA. While Congress has not passed
comprehensive repeal legislation, two bills affecting the implementation of certain taxes under the ACA have been signed into law. The Tax Cuts and Jobs
Act  of  2017  includes  a  provision  that  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.” In addition, 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.  In  July  and  December  2018,  Centers  for
Medicare & Medicaid Services, or CMS, within the United States Department of Health and Human Services, published final rules with respect to permitting
further collections and payments to and from certain ACA qualified health plans and health insurance issuers under its risk adjustment program in response
to the outcome of federal district court litigation regarding the method CMS uses to determine this risk adjustment. On December 14, 2018, a Texas U.S.
District Court Judge ruled that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by the U.S. Congress as part of the
Tax Cuts and Jobs Act of 2017 Act. Additionally, on December 18, 2019, the U.S. Court of Appeals for the 5th Circuit upheld the Texas U.S. District Court
ruling and remanded the case back to the District Court to determine whether the remaining provisions of the ACA are invalid as well. It is unclear how this
decision, subsequent appeals, and other efforts to repeal and replace the ACA will impact the ACA.

24

 
 
 
 
 
 
 
 
Other legislative changes have been proposed and adopted since the ACA was enacted. These changes include aggregate reductions to Medicare payments to
providers of 2% per fiscal year, which went into effect in April 2013 and will remain in effect through 2027 unless additional Congressional action is taken.
Both the Budget Control Act of 2011 and the American Taxpayer Relief Act of 2012, or ATRA, further reduced Medicare payments to several providers and
the ATRA 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 demand and prices for our product candidates, if approved. This could harm our or our partners’ ability to market any
drugs and generate revenues. Cost containment measures that healthcare payors and providers are instituting and the effect of further healthcare reform could
significantly reduce potential revenues from the sale of any of our product candidates approved in the future, and could cause an increase in our compliance,
manufacturing, or other operating expenses.

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  U.S.  Bureau  of  Labor  Statistics  consumer  price  index,  and  these  rebates  or  discounts,  which  can  be
substantial, may affect our ability to raise commercial prices.

Further, there has been increasing legislative and enforcement interest in the United States with respect to drug pricing practices. Specifically, there have
been  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 drugs. At the federal level, the Trump administration’s budget proposal for fiscal years 2020
contains further drug price control measures that could be enacted during the budget process or in other future legislation. The Trump administration also
released  a  “Blueprint”,  or  plan,  to  lower  drug  prices  and  reduce  out  of  pocket  costs  of  drugs  that  contains  additional  proposals  to  increase  manufacturer
competition, increase the negotiating power of certain federal healthcare programs, incentivize manufacturers to lower the list price of their products and
reduce the out of pocket costs of drug products paid by consumers. For example, in May 2019, CMS issued a final rule to allow Medicare Advantage Plans
the option of using step therapy for Part B drugs beginning January 1, 2020. This final rule codified CMS’s policy change that was effective January 1, 2019.
While some measures may require additional authorization to become effective, the U.S. Congress and the Trump administration have each indicated that it
will continue to seek new legislative and/or administrative measures to control drug costs. At the state level, legislatures are increasingly passing legislation
and  implementing  regulations  designed  to  control  pharmaceutical  and  biological  product  pricing,  including  price  or  patient  reimbursement  constraints,
discounts,  restrictions  on  certain  product  access  and  marketing  cost  disclosure  and  transparency  measures,  and,  in  some  cases,  designed  to  encourage
importation from other countries and bulk purchasing.

25

 
 
 
 
 
 
In some countries, the proposed pricing for a biopharmaceutical product must be approved before it may be lawfully marketed. In addition, in certain foreign
markets, the pricing of biopharmaceutical product 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.
An EU member state may approve a specific price for the medicinal product, it may refuse to reimburse a product at the price set by the manufacturer 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. 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 any of our products. 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.

We believe that pricing pressures will continue and may increase, which may make it difficult for us to sell Lumoxiti or any of our product candidates that
may be approved in the future at a price acceptable to us or any of our existing or future collaborators.

Lumoxiti and any of our other product candidates, if approved and commercialized, may fail to achieve market acceptance by physicians, patients, third-
party payors or the medical community to a degree that is 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  drug  is  preferable  to  any  existing  drugs  or
treatments.  We  cannot  predict  the  degree  of  market  acceptance  of  Lumoxiti  or  any  product  candidate  that  receives  marketing  authorization,  which  will
depend on a number of factors, including, but not limited to:

·

·

·

·

·

·

·

·

·

·

·

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

the approved labeling for the drug and any required warnings;

prevalence and severity of adverse side effects;

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

ease of the drug’s use;

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

the scope of any approval provided by the FDA or foreign regulatory authorities;

publicity about our product or about competitive products;

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

the market price of our drugs relative to competing treatments; and

due to the rarity of orphan diseases, it could be difficult finding patients seeking treatment for Lumoxiti.

26

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Poor market penetration could have an adverse effect on our business, prospects, financial condition and results of operations.

Even  if  some  of  our  other  product  candidates  receive  marketing  authorization,  the  terms  of  such  approval,  ongoing  regulation  and  potential  post-
marketing restrictions or withdrawal from the market may limit how the drug may be marketed and may subject us to penalties for failure to comply with
regulatory requirements, which could impair our ability to generate revenues.

Even if any of our other product candidates receives marketing authorization, such approval may carry conditions that limit the market for the drug or put the
drug  at  a  competitive  disadvantage  relative  to  alternative  therapies.  Regulators  may  limit  the  marketing  of  products  to  particular  indications  or  patient
populations. Regulators may require warning labels and drugs with warnings are subject to more restrictive marketing regulations than drugs without such
warnings. These restrictions could make it more difficult to market any drug effectively. Marketing restrictions may reduce the revenue that we are able to
obtain.

Any of our product candidates for which we obtain marketing authorization, and 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 FDA, EMA 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 authorization 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 risk evaluation and mitigation strategy to ensure that the benefits of a drug or biological product outweigh its risks.

The FDA, EMA and other national authorities 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 U.S. 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.  Later  discovery  of  previously  unknown
problems with our product candidates or with manufacturing processes, including adverse events of unanticipated severity or frequency, or failure to comply
with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical
studies to assess new safety risks, or the imposition of distribution or other restrictions including suspension of production and/or distribution and withdrawal
of regulatory approvals. Failure to comply with these requirements may lead to financial penalties, compliance expenditures, total or partial suspension of
production  and/or  distribution,  product  seizure  or  detention,  refusal  to  permit  the  import  or  export  of  products,  suspension  of  the  applicable  regulator’s
review  of  a  company’s  submissions,  enforcement  actions,  product  recalls,  injunctions  and  even  criminal  prosecution,  any  of  which  could  materially  and
adversely affect our business, financial condition and results of operations.

27

 
 
 
 
 
 
The recent global COVID-19 pandemic could adversely affect our business, financial condition and results of operations.

An outbreak of a novel strain of coronavirus (i.e. COVID-19), which first emerged in the PRC in late December 2019, has since spread to other parts of the
world, including the United States and Europe. We may experience or continue to experience disruptions relating to this pandemic that could severely impact
our business, financial condition and results of operations.

In France, on March 12, 2020, the French government announced the closure of all schools and the closure of all non-essential businesses until further notice.
On  March  16,  2020,  President  Macron  announced  the  confinement  of  the  French  population  for  a  minimum  of  15  days.  Such  confinement  has  been
subsequently extended and, on April 13, 2020, President Macron announced that such confinement will not be lifted until at least May 11, 2020. On March
13,  2020,  President  Trump  declared  a  national  emergency  under  the  Robert  T.  Stafford  Disaster  Relief  and  Emergency  Assistance  Act  of  1988,  and
subsequently, many U.S. states closed their schools and public gathering places.

Because of these containment measures, we have temporarily closed all of our corporate sites in France and the United States, and in particular our Luminy
site,  where  we  carry  out  our  laboratory  experiments.  However,  our  Luminy  site  has  been  partially  reopened  for  our  exploratory  study  on  COVID-19
therapies. We may take further actions required by authorities or that we determine are in the best interests of our employees, customers, partners, suppliers
and  counterparts.  We  cannot  be  certain  that  such  measures  will  be  sufficient  to  mitigate  the  risks  posed  by  COVID-19,  and  the  implementation  of  such
measures (or their insufficiency) could harm our ability to perform critical functions. The unavailability of our staff could adversely impact the quality and
continuity  of  our  operations.  Furthermore,  we  expect  these  containment  measures  to  delay  our  planned  recruitment  of  additional  employees,  which  is
necessary to support our growth.

The closure of our sites could also cause a delay in obtaining certain data from our research and development programs, and thereby delay our mid-term
development timelines. Restarting the Luminy site and its activities could be a potentially long, costly and complex process.

Because of the spread of COVID-19, we may experience or continue to experience the following adverse impacts on our clinical trials:

·

·

·

·

·

diversion  of  investigational  sites  and  physicians  adhering  to  government  recommended  protocols  that  interfere  with  our  clinical  trials,  including  the
clinical trials carried out by our hospital or industrial partners, whose crisis management decisions are not under our control;

delays or difficulties in enrolling new patients in our clinical trials;

delays or difficulties in continuing treatment of patients already enrolled in our clinical trials, which delays obtaining results from such trials;

delays  or  interruptions  of  key  clinical  trial  activities  due  to  shortages  or  interruptions  in  the  supply  chain  of  third-party  marketed  drugs  used  in
connection with our products in our clinical trials as well as active pharmaceutical ingredients or components used to manufacture our marketed drugs;

deterioration of the quality and completeness of data obtained during our clinical trials due to limitations in patient monitoring as a result of containment
measures  and  the  possibility  of  participating  patients  to  be  infected  with  COVID-19,  which  could  result  in  refusals  of  local  regulatory  authorities  to
accept data from such clinical trials;

28

 
 
 
 
 
 
 
 
 
 
 
·

·

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

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, or the need of these institutions to prioritize COVID-19 matters.

It is not only true for trials we sponsor but also for trials sponsored by academic or industrial partners, which might take decision in this context that we
cannot control.  We expect those factors to have a higher impact on our product candidates at early clinical trial stages. For example, AstraZeneca has made
the decision to temporarily pause enrollment of the Phase I clinical trial evaluating IPH5201, an anti-CD39 blocking monoclonal antibody, in adult patients
with advanced solid tumors, due to the COVID-19 pandemic.

The  COVID-19  pandemic  could  also  delay  or  impair  our  sales  of  Lumoxiti.  Since  the  end  of  the  fourth  quarter  of  2019,  we  have  become  the  primary
commercial  entity  promoting  Lumoxiti,  having  transitioned  all  sales  and  medical  affairs  activities,  including  medical  science  liaisons  and  sales
representatives,  from  AstraZeneca  to  us.  The  COVID-19  pandemic  could  impair  our  ability  to  achieve  our  product  development  or  commercialization
objectives in the timeframes we had expected due to the factors listed above and, also due to limited opportunities for in-person marketing of Lumoxiti to
oncology  healthcare  professionals  due  to  social  distancing  measures  and  interruptions  of  treatments  for  Lumoxiti  patients  as  a  result  of  limited  access  to
physicians.

As  a  consequence,  we  may  not  receive  milestone  or  royalty  payments  from  our  partners.  See  “—If  we  do  not  achieve  our  product  development  or
commercialization objectives in the timeframes we expect, we may not receive product revenue or milestone or royalty payments and we may not be able to
conduct our operations as planned.”

The global COVID-19 pandemic continues to evolve. The extent to which the COVID-19 pandemic may affect 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. Further, the
adverse effect on the financial markets, on the market price of our ADSs and/or ordinary shares in the long term, is unknown. To date, the global economy
remains catastrophically affected by the outbreak of the COVID-19 pandemic.

29

 
 
 
 
 
 
 
 
 
 
We are exposed to a number of regulatory and commercial risks relating to the United Kingdom’s exit from the European Union.

The United Kingdom formally withdrew from the EU (“Brexit”) on January 31, 2020 on the basis of the Third Reading of the Withdrawal Agreement Bill.
There will be a short transitional/implementation period which is currently due to end on December 31, 2020 during which the United Kingdom and the EU
are negotiating transitional arrangements. The United Kingdom has stated that it wants the transition period to expire, and the transitional arrangements to be
agreed, by December 31, 2020. During the transition period the existing rules on trade, travel, and business for the United Kingdom and the EU continue to
apply.  Any  changes  that  may  occur  after  the  transitional  period  are  currently  uncertain.  There  is  still  concern  that  the  United  Kingdom  does  not  find  an
agreement with the EU regarding such transitional arrangements and the U.K. Government has commenced preparations for a “hard” or “no-deal” Brexit to
minimize the risks for firms and businesses associated with an exit with no transitional agreement.

Our clinical trials in the U.K. are subject to the UK Medicines and Healthcare Products Regulatory Agency, or MHRA and EMA regulations. If the U.K.
proceeds  to  leave  the  EU  without  any  formal  withdrawal  arrangements,  there  could  be  considerable  uncertainty  as  to  the  continued  applicability  of  such
regulations in the U.K. We are currently conducting clinical trials of lacutamab in the U.K. and we cannot be certain such trials will not be affected if the
U.K. leaves the EU without any formal withdrawal arrangements. Lacutamab received an orphan drug designation in the EU, which provides for an exclusive
10-year  marketing  period  during  which  no  similar  product  may  apply  for  a  marketing  authorization  in  the  EU  for  the  same  indication,  as  well  as  an
exemption from regulatory fees and other advantages. We may lose this designation and benefits for lacutamab in the U.K. in the event that the U.K. exits the
EU without any formal withdrawal arrangements. Furthermore, if we obtain an MA in the EU, such authorization may not permit us to engage in commercial
sales of our product candidates in the U.K. and we may not be able to obtain the required authorization from the U.K. regulator. If we are required to obtain
additional authorizations in the U.K., we will incur additional costs to obtain such authorizations, which may be significant.

Risks Related to our Financial Position and Capital Needs

We have incurred and may in the future incur significant operational losses related to our research and development activities.

We have incurred net losses in each year since our inception except for the years ended December 31, 2016 and 2018. Our net income (loss) was €(48.4)
million, €3.0 million and €(20.8) million for the years ended December 31, 2017, 2018 and 2019, respectively. Substantially all of our net losses resulted
from  costs  incurred  in  connection  with  our  development  programs  and  from  selling,  general  and  administrative  expenses  associated  with  our  ongoing
operations. We expect to incur significant expenses and operating losses for the foreseeable future.

We currently only have one product, Lumoxiti, that has received regulatory approval for sale or has generated revenues from commercial sales, and none of
our other product candidates have received regulatory approval. Unless this happens, the likelihood and amount of our future operational losses will depend
on several factors, including the commercialization of our approved product, Lumoxiti, the pace and amount of our future expenditures in connection with
our  product  candidates  and  development  programs  and  our  ability  to  obtain  funding  through  milestone  or  royalty  payments  under  our  license  and
collaboration  agreements,  equity  or  debt  financings,  strategic  collaborations  and  government  grants  and  tax  credits.  We  expect  that  our  main  source  of
income for the near- and medium-term will be:

30

 
 
 
 
 
 
 
 
 
 
·

·

·

revenue from the commercialization of Lumoxiti;

payments received under our license and collaboration agreements with third parties, including AstraZeneca and Sanofi; and

government grants and research tax credits.

The interruption of one of those sources of income, including as a result of the COVID-19 pandemic, could have a material adverse effect on our business,
prospects,  financial  condition  and  results  of  operations.  See  “—The  recent  global  COVID-19  pandemic  could  adversely  affect  our  business,  financial
condition and results of operations.”

Our ability to be profitable in the future will depend on our ability to generate revenue from sales relating to our sole commercial product, Lumoxiti, and
other product candidates, if approved, and our ability to obtain regulatory approval for marketing our product candidates. If our product candidates receive
regulatory  approval,  our  future  revenues  will  depend  upon  the  size  of  any  markets  in  which  our  product  candidates  have  received  approval,  and  market
acceptance, reimbursement from third-party payors and market share. Any of these factors could have a material adverse effect on our business, prospects,
financial condition and results of operations.

We may need to raise additional funding to complete the development and any commercialization of our product candidates, 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 or other operations.

We are currently advancing our product candidates through preclinical and clinical development, and anticipate relying on partners less as we develop into a
commercial  stage  biopharmaceutical  company  with  research,  development  and  commercial  capabilities.  We  currently  retain  the  full  development  and
marketing  rights  to  lacutamab  and  avdoralimab  and  may  retain  rights  to  additional  proprietary  product  candidates  in  the  future.  The  development  of
immunotherapy product candidates is expensive, and we expect our research and development expenses to increase as we advance our product candidates
through clinical trials and regulatory approvals. If clinical trials are successful and if we obtain regulatory approval for product candidates that we develop,
we expect to incur commercialization expenses before these product candidates are marketed and sold.

We anticipate that our expenses will increase substantially if and as we:

·

·

·

·

·

·

·

continue our research, preclinical and clinical development of our product candidates if our current collaboration partners cease their collaborations
with us;

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

initiate additional preclinical, clinical or other studies for our product candidates;

further develop manufacturing processes for our product candidates;

change or add additional manufacturers or suppliers;

seek regulatory and marketing authorizations for our product candidates that successfully complete clinical studies;

establish  a  sales,  marketing  and  distribution  infrastructure  to  commercialize  Lumoxiti  and  any  other  products  for  which  we  may  obtain  marketing
authorization;

31

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
·

·

·

·

·

·

·

seek to identify and validate additional product candidates that may result in additional preclinical, clinical or other product studies;

acquire or in-license other product candidates and technologies;

make milestone or other payments under any in-license agreements;

maintain, protect, defend and expand our intellectual property portfolio;

attract and retain new and existing skilled personnel;

create  additional  infrastructure  to  support  our  operations  as  a  public  company  in  the  United  States  following  the  completion  of  the  October  2019
global offering; and

experience any delays or encounter issues with any of the above.

As of December 31, 2019, we had cash, cash equivalents, short-term investments and non-current financial assets of €255.9 million. We believe our cash,
cash  equivalents,  short-term  investments  and  non-current  financial  assets  together  with  our  cash  flow  from  operations,  will  be  sufficient  to  fund  our
operations for the next twelve months. However, in order to complete the development process, obtain regulatory approval and, if approved, commercialize
our product candidates that we are developing in-house, including lacutamab and avdoralimab, develop our proprietary technology and develop a pipeline of
additional product candidates, we will require additional funding. Our existing resources may not be sufficient to cover any additional financing needs, in
which case new funding would be required. See “—We have incurred and may in the future incur significant operational losses related to our research and
development activities.” The conditions and arrangements for such new financing would depend, among other factors, on economic and market conditions
that are beyond our control, including the current volatility in the capital markets as a result of the COVID-19 pandemic. See “—The recent global COVID-
19 pandemic could adversely affect our business, financial condition and results of operations.”

Any  additional  fundraising  efforts  may  divert  our  management  from  their  day-to-day  activities,  which  may  adversely  affect  our  ability  to  develop  and
commercialize our product candidates. In addition, we cannot guarantee that future financing will be available in sufficient amounts or on terms acceptable to
us, if at all. Under French law, our share capital may be increased only with shareholders’ approval at an extraordinary general shareholders’ meeting on the
basis of a report from the Executive Board. In addition, the French Commercial Code imposes certain limitations on our ability to price certain offerings of
our share capital without preferential subscription rights (droit préférentiel de souscription), which limitation may prevent us from successfully completing
any such offering. See “Description of Share Capital—Key Provisions of Our Bylaws and French Law Affecting Our Ordinary Shares.”

Moreover, the terms of any financing may adversely affect the holdings or the rights of our shareholders and the issuance of additional securities, whether
equity or debt, by us, or the possibility of such issuance, may cause the market price of our ordinary shares or the ADSs to decline. The sale of additional
equity or convertible securities would dilute our shareholders. We may seek funds through arrangements with collaborative partners or otherwise at an earlier
stage  of  product  development  than  otherwise  would  be  desirable  and  we  may  be  required  to  relinquish  rights  to  some  of  our  technologies  or  product
candidates or otherwise agree to terms unfavorable to us, any of which may have a material adverse effect on our business, prospects, financial condition and
results of operations.

32

 
 
 
 
 
 
 
 
 
 
 
 
 
If we need and are unable to obtain funding on a timely basis, we may be required to significantly curtail, delay or discontinue one or more of our research or
development programs or the commercialization of any product or product candidate or we may be unable to expand our operations or otherwise capitalize
on our business opportunities as desired, which could impair our growth prospects. Should any of these risks materialize, this could have a material adverse
effect on our business, prospects, financial condition and results of operations.

The terms of our loan agreement with Société Générale and certain other loan obligations place restrictions on our operating and financial flexibility.

In July 2017, we entered into a loan and security agreement with Société Générale (the “Loan Agreement”) in order to finance the construction of our future
headquarters.  The  Loan  Agreement  is  secured  by  collateral  in  the  form  of  financial  instruments  valued  at  €15.2  million  held  at  Société  Générale.  As  of
December 31, 2019, we had drawn down €15.2 million under the Loan Agreement. The Loan Agreement subjects us to a covenant to maintain a minimum
balance of our total cash, cash equivalents and current and non-current financial assets as of each fiscal year end at least equal to the amount of outstanding
principal under the Loan Agreement. Compliance with this covenant may limit our flexibility in operating our business and our ability to take actions that
might be advantageous to us and our shareholders. For example, if we fail to meet our minimum cash covenant and we are unable to raise additional funds or
obtain  a  waiver  or  other  amendment  to  the  Loan  Agreement,  we  may  be  required  to  delay,  limit,  reduce  or  terminate  certain  of  our  clinical  development
efforts.

Additionally, we may be required to repay the entire amount of outstanding indebtedness under the Loan Agreement in cash if we fail to stay in compliance
with our covenant or suffer some other event of default under the Loan Agreement. Under the Loan Agreement, an event of default will occur if, among
other things, we fail to make payments under the Loan Agreement or we breach our covenant under the Loan Agreement. We may not have enough available
cash or be able to raise additional funds through equity or debt financings to repay such indebtedness at the time any such event of default occurs. In that
case,  we  may  be  required  to  delay,  limit,  reduce  or  terminate  our  clinical  development  efforts  or  grant  rights  to  others  to  develop  and  market  product
candidates  that  we  would  otherwise  prefer  to  develop  and  market  ourselves.  Société  Générale  could  also  exercise  its  rights  as  collateral  agent  to  take
possession and dispose of the collateral securing the loan for its benefit. Our business, financial condition and results of operations could be substantially
harmed as a result of any of these events.

We are also subject to a €1.5 million PTZI loan (Prêt à Taux Zéro Innovation—interest-free loan for innovation) from Banque Publique d’Investissement, or
BPI France, entered into in 2013. In addition, in 2008 we entered into a finance lease agreement with Sogebail, a subsidiary of Société Générale. The present
value  of  all  minimum  lease  payments  under  this  agreement  is  €0.3  million  as  of  December  31,  2019.  Our  business,  financial  condition  and  results  of
operations  could  likewise  be  substantially  harmed  if,  among  other  things,  we  fail  to  make  payments  under  these  agreements,  or  we  breach  any  of  our
covenants under these agreements.

33

 
 
 
 
 
 
 
 
If  we  do  not  achieve  our  product  development  or  commercialization  objectives  in  the  timeframes  we  expect,  we  may  not  receive  product  revenue  or
milestone or royalty payments and we may not be able to conduct our operations as planned.

We have received and expect to continue to receive payments from our collaborators when we satisfy certain pre-specified milestones in our licensing or
collaboration agreements. We currently depend to a large degree on these milestone payments from our existing collaborators in order to fund our operations
and we may enter into new collaboration agreements that also provide for milestone payments. For example, we have granted options to license or acquire
intellectual property rights in certain of our programs to our collaborators which, if exercised, will result in up-front option exercise fees and, assuming we
meet  all  specified  development,  clinical,  regulatory  and  sales  milestones,  could  result  in  substantial  milestone  payments.  These  milestone  payments  are
generally dependent on the accomplishment of various scientific, clinical, regulatory, sales and other product development objectives, and the successful or
timely  achievement  of  many  of  these  milestones  is  outside  of  our  control,  in  part  because  some  of  these  activities  are  being  or  will  be  conducted  by  our
collaborators. If we or our collaborators fail to achieve the applicable milestones, we may not receive such milestone payments. A failure to receive any such
milestone payment may cause us to:

·

·

·

·

·

·

delay, reduce or terminate certain research and development programs;

reduce headcount;

raise funds through additional equity or convertible debt financings that could be dilutive to our shareholders and holders of our ADSs;

obtain funds through collaboration agreements that may require us to assign rights to technologies or products that we would have otherwise retained;

sign new collaboration or license agreements that may be less favorable than those we would have obtained under different circumstances; and

consider strategic transactions or engaging in a joint venture with a third-party.

In addition, although we may be eligible to receive an aggregate of approximately $5.5 billion in future contingent payments from existing collaboration
agreements and any license agreements that become effective upon the exercise by our collaborators of options to license future product candidates, there is
no  guarantee  that  we  will  receive  any  contingent  payments  or  that  our  collaborators  will  exercise  any  options  to  license  or  acquire  additional  intellectual
property rights in any of our programs. If our collaborators decide not to exercise such options with respect to a program, we will not receive the up-front
option  exercise  fee  and  will  not  be  eligible  to  receive  any  of  the  related  commercial,  development,  royalty  or  other  milestone  payments.  Even  if  our
collaborators exercise such options with respect to a particular program, we may never achieve the related milestones for any number of reasons. The failure
to  receive  milestone  or  royalty  payments  and  the  occurrence  of  any  of  the  events  above  may  have  a  material  adverse  impact  on  our  business,  prospects,
financial condition and results of operations.

The revenues generated from our collaboration and license agreements have contributed and are expected to contribute a large portion of our revenue
for the foreseeable future.

34

 
 
 
 
 
 
 
 
 
 
 
 
 
We have entered into collaboration and license agreements with pharmaceutical companies, including AstraZeneca. The cash payments received from our
partners were €14.0 million, €40.3 million and €108.6 million for the years ended December 31, 2017, 2018 and 2019, respectively.

We also enhance our research efforts by establishing collaborations with academic or non-profit research institutions and other biopharmaceutical companies.
The  participation  in  these  collaborations  may  generate  revenue  and  funding  in  the  form  of  operating  grants  or  the  reimbursement  of  research  and
development expenses.

We may not be able to renew or maintain our license agreements or collaborative research contracts or may be unable to sign new agreements with new
collaborators on reasonable terms or at all. The early termination of a contract, the non-renewal of a contract or our inability to find new collaborators would
adversely  affect  our  business.  Should  any  of  these  risks  materialize,  this  could  have  an  adverse  effect  on  our  business,  prospects,  financial  condition  and
results of operations.

We benefit from tax credits in France that could be reduced or eliminated.

As a French biopharmaceutical company, we benefit from certain tax advantages, including the Research Tax Credit (Crédit Impôt Recherche), which is a
French tax credit aimed at stimulating research and development. The Research Tax Credit is calculated based on our claimed amount of eligible research
and development expenditures in France and represented €11.0 million, €13.5 million and €16.7 million for the years ended December 31, 2017, 2018 and
2019, respectively. The Research Tax Credit is a source of financing to us that could be reduced or eliminated by the French tax authorities or by changes in
French tax law or regulations.

The Research Tax Credit can be offset against French corporate income tax due by the company with respect to the year during which the eligible research
and development expenditures have been made. The portion of tax credit in excess which is not being offset, if any, represents a receivable against the French
Treasury  which  can  in  principle  be  offset  against  the  French  corporate  income  tax  due  by  the  company  with  respect  to  the  three  following  years.  The
remaining portion of tax credit not being offset upon expiry of such a period may then be refunded to the company.

Until the end of the year ended December 31, 2018, we qualified as a small- and medium-size business and the French Treasury refunded each of our 2016,
2017 and 2018 Research Tax Credit claims immediately (meaning that, in practice, we received the refund during the year following the year in which the
eligible research and development expenditures are made). We no longer qualify as a small and medium-size business for the year ended December 31, 2019,
and therefore, we will no longer be entitled to the immediate reimbursement of the Research Tax Credit but instead will be reimbursed within the expiry of
the period of three years mentioned above.

The French tax authorities, with the assistance of the Higher Education and Research Ministry, may audit each research and development program in respect
of which a Research Tax Credit benefit has been claimed and assess whether such program qualifies in their view for the Research Tax Credit 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 (and therefore the amount of Research Tax Credit claimed), or the accelerated reimbursement allowed for small- and medium-size businesses and
our credits may be reduced, which would have a negative impact on our revenue and future cash flows. Furthermore, the French Parliament may decide to
eliminate, or to reduce the scope or the rate of, the Research Tax Credit benefit, either of which it could decide to do at any time. If we fail to receive future
Research Tax Credit amounts or if our calculations are challenged, even if we comply with the current requirements in terms of documentation and eligibility
of its expenditure, our business, prospects, financial condition and results of operations could be adversely affected.

35

 
 
 
 
 
 
 
 
 
 
 
We may be unable to carry forward existing tax losses.

We have accumulated tax loss carry forwards of €230.6 million as of December 31, 2019. Applicable French law provides that, for fiscal years ending after
December 31, 2012, the use of these tax losses is limited to €1.0 million, plus 50% of the portion of net earnings exceeding this amount. The unused balance
of the tax losses in application of such rule can be carried forward to future fiscal years, under the same conditions and without time restriction. There can be
no  assurance  that  future  changes  to  applicable  tax  law  and  regulation  will  not  eliminate  or  alter  these  or  other  provisions  in  a  manner  unfavorable  to  us,
which could have an adverse effect on our business, prospects, financial condition, cash flows or results of operations.

Changes to U.S. and non-U.S. tax laws could materially adversely affect our company.

On December 22, 2017, the Tax Cuts and Jobs Act was signed into law and significantly revised the Internal Revenue Code of 1986, as amended, or the
Code. The Tax Cuts and Jobs Act, among other things, contains significant changes to corporate taxation, including reduction of the corporate tax rate from a
top marginal rate of 35% to a flat rate of 21%, limitation of the tax deduction for interest expense to 30% of adjusted taxable income (except for certain small
businesses),  implementation  of  a  “base  erosion  anti-abuse  tax,”  which  requires  U.S.  corporations  to  make  an  alternative  determination  of  taxable  income
without regard to tax deductions for certain payments to affiliates, taxation of certain non-U.S. corporations’ earnings considered to be “global intangible low
taxed income,” which is also referred to as GILTI, repeal of the alternative minimum tax, or AMT, for corporations and changes to a taxpayer’s ability to
either utilize or refund the AMT credits previously generated, changes to the limitation on deductions for certain executive compensation particularly with
respect  to  the  removal  of  the  previously  allowed  performance  based  compensation  exception,  changes  in  the  attribution  rules  relating  to  shareholders  of
certain “controlled foreign corporations,” limitation of the deduction for net operating losses to 80% of current year taxable income and elimination of net
operating  loss  carrybacks,  one-time  taxation  of  offshore  earnings  at  reduced  rates  regardless  of  whether  they  are  repatriated,  elimination  of  U.S.  tax  on
foreign earnings (subject to certain important exceptions), immediate deductions for certain new investments instead of deductions for depreciation expense
over time, and modifying or repealing many business deductions and credits. Notwithstanding the reduction in the U.S. corporate income tax rate, the overall
impact of the Tax Cuts and Jobs Act is uncertain and our business and financial condition could be adversely affected. The impact of the Tax Cuts and Jobs
Act on holders of our ordinary shares or ADSs is also uncertain and could be adverse. For example, recent changes in U.S. federal income tax law resulting
in additional taxes owed by U.S. holders (as described under “Material United States Federal Income Tax and French Tax Considerations—Material U.S.
Federal  Income  Tax  Considerations”)  under  the  new  GILTI  tax  rules  or  related  to  “controlled  foreign  corporations”  may  discourage  U.S.  investors  from
owning or acquiring 10% or greater of our outstanding ordinary shares or ADSs, which other shareholders may have viewed as beneficial or may otherwise
negatively impact the trading price of our ordinary shares or ADSs. We are unable to predict what federal tax law 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 legislation, regulations, policies or practices,
could affect our effective tax rates in the future in countries where we have operations and have an adverse effect on our overall tax rate in the future, along
with increasing the complexity, burden and cost of tax compliance. In addition, several of the measures implemented by the Tax Cuts and Jobs Act, including
several of those discussed above, have been temporarily modified pursuant to the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”),
which was signed into law on March 27, 2020. We urge our shareholders and holders of our ADSs to consult with their legal and tax advisors with respect to
the Tax Cuts and Jobs Act, including the modifications made pursuant to the CARES Act and the potential tax consequences of investing in or holding our
ordinary shares or ADSs.

36

 
 
 
 
 
 
 
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 French tax authorities, 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 result could increase our anticipated effective tax rate.

Risks Related to Regulatory Approval and Marketing of Our Product Candidates and Legal Compliance Matters

Even if we complete the necessary preclinical studies and clinical trials, the marketing approval process is expensive, time-consuming and uncertain and
may prevent us from obtaining approvals for the commercialization of some or all of our product candidates. If we are not able to obtain, or if there are
delays in obtaining, required regulatory approvals, in particular in the United States or the European Union, we will not be able to commercialize our
product candidates, and our ability to generate revenue will be materially impaired.

The  research  and  development  of  pharmaceutical  products  is  governed  by  complex  regulatory  requirements.  The  regulatory  agencies  that  oversee  these
requirements  have  the  authority  to  permit  the  commencement  of  clinical  trials  or  to  temporarily  or  permanently  halt  a  study.  They  are  entitled  to  request
additional clinical data before authorizing the commencement or resumption of a study, which could result in delays or changes to our product development
plan. As we advance our product candidates, we will be required to consult with these regulatory agencies and comply with all applicable guidelines, rules
and  regulations.  If  we  fail  to  do  so,  we  may  be  required  to  delay  or  discontinue  development  of  our  product  candidates.  Delay  or  failure  to  obtain,  or
unexpected  costs  in  obtaining,  the  regulatory  approval  necessary  to  bring  a  potential  product  to  market  could  decrease  our  ability  to  generate  sufficient
product revenue to maintain our business.

37

 
 
 
 
 
 
 
 
The  clinical  trials  of  our  product  candidates  are,  and  the  manufacturing  and  marketing  of  our  one  approved  product,  Lumoxiti,  and  our  other  product
candidates will be, subject to regulation by numerous government authorities in the United States, in the European Union and in other countries where we
intend to test and, if approved, market any product candidate. Before obtaining regulatory approvals for the commercial sale of any product candidate, we
must demonstrate, with substantial evidence gathered in well-controlled clinical trials, and, with respect to approval in the United States, to the satisfaction of
the FDA, with respect to approval in the European Union, to the satisfaction of the EMA or, with respect to approval in other countries, similar regulatory
authorities in those countries, that the product candidate is safe and effective for use in each target indication.

When  we  acquired  Lumoxiti,  AstraZeneca  had  already  obtained  marketing  approval  from  the  FDA.  We  have  never  submitted  a  product  candidate  for
marketing approval in the United States or elsewhere.

In the United States, we expect that the requisite regulatory submission to seek marketing authorization for our product candidates will be a Biologic License
Application, or BLA, and the competent regulatory authority is the FDA. In the European Union, the requisite approval is a Marketing Authorization, or MA,
which for products developed by the means of antibody-based therapeutics, gene or cell therapy products as well as tissue engineered products, is issued
through a centralized procedure involving the EMA (see “Business—Regulation”). We submitted an MA application for Lumoxiti to the EMA, but have not
received  the  MA  yet  and  may  not  receive  it.  Satisfaction  of  these  and  other  regulatory  requirements  is  costly,  time  consuming,  uncertain  and  subject  to
unanticipated  delays.  Failure  to  comply  with  the  applicable  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, for example, 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, or civil or criminal penalties.

Data from preclinical and clinical studies are likely to give rise to different interpretations, which could delay regulatory authorization, restrict the scope of
any such authorization or force us to repeat trials in order to meet the requirements of the various regulators. Regulatory requirements and processes vary
widely among countries, and we may be unable to obtain authorization within each relevant country in a timely manner. Regulatory authorities may prevent
us from starting clinical trials or continuing clinical development if the data were not produced according to applicable regulations or if they consider that the
balance between the expected benefits of the product and its possible risks is not sufficient to justify the trial.

Despite our efforts, our product candidates may not:

·

·

offer improvement over existing, comparable products;

be proven safe and effective in clinical trials; or

38

 
 
 
 
 
 
 
 
 
 
·

meet applicable regulatory standards.

This  process  can  take  many  years  and  may  include  post-marketing  studies  and  surveillance,  which  will  require  the  expenditure  of  substantial  resources
beyond  our  existing  cash  on  hand.  Of  the  large  number  of  drugs  in  development  globally,  only  a  small  percentage  successfully  complete  the  regulatory
approval process and not all approved drugs are successfully commercialized. Delay or failure to obtain, or unexpected costs in obtaining, the regulatory
approval necessary for us or our partners to bring a potential product candidate to market could have a material adverse effect on our business, prospects,
financial condition and results of operations.

The regulatory processes that will govern the approval of our product candidates are complex and changes in regulatory requirements could result in
delays or discontinuation of development or unexpected costs in obtaining regulatory approval.

Our  product  candidates  are  based  on  new  technologies  that  are  constantly  evolving  and  have  not  been  extensively  tested  on  humans.  The  applicable
regulatory requirements vary between jurisdictions and are also complex, potentially difficult to apply and subject to significant modifications. Modifications
to regulations during the course of clinical development and regulatory review may lead to delays or the refusal of authorization.

In Europe, the United States and other countries, regulations can potentially:

·

·

·

significantly delay or increase the cost of development, testing, manufacturing and marketing of our products;

limit the indications for which we will be authorized to market our products; and

impose  new,  more  stringent,  requirements,  suspend  marketing  authorizations,  or  request  the  suspension  of  clinical  trials  or  the  marketing  of  our
products if unexpected results are obtained during trials performed by other researchers on products similar to our products.

Marketing authorization in one jurisdiction does not ensure marketing authorization in another, but a failure or delay in obtaining marketing authorization in
one jurisdiction may have a negative effect on the regulatory process in others. Failure to obtain marketing authorization in other countries or any delay or
setback in obtaining such approval would impair our ability to develop additional markets for our product, Lumoxiti, or any additional product candidates
that are approved. This would reduce our target market and limit the full commercial potential of our product or product candidates. Should any of these risks
materialize, this could harm our business.

Our  failure  to  obtain  marketing  approval  in  jurisdictions  other  than  the  United  States  and  Europe  would  prevent  our  product  candidates  from  being
marketed in these other jurisdictions, and any approval we are granted for our product candidates in the United States and Europe would not assure
approval of product candidates in other jurisdictions.

In  order  to  market  and  sell  our  other  product  candidates  in  jurisdictions  other  than  the  United  States  and  Europe,  we  must  obtain  separate  marketing
approvals and comply with numerous and varying regulatory requirements. The approval process varies among countries and can involve additional testing.
The time required to obtain approval may differ from that required to obtain FDA approval or approvals from regulatory authorities in the European Union.
The regulatory approval process outside the United States and Europe generally includes all of the risks associated with obtaining FDA approval or approvals
from regulatory authorities in the European Union. In addition, some countries outside the United States and Europe require approval of the sales price of a
product before it can be marketed. In many countries, separate procedures must be followed to obtain reimbursement and a product may not be approved for
sale in the country until it is also approved for reimbursement. We may not obtain marketing, pricing or reimbursement approvals outside the United States
and  Europe  on  a  timely  basis,  if  at  all.  Approval  by  the  FDA  or  regulatory  authorities  in  the  European  Union  does  not  ensure  approval  by  regulatory
authorities in other countries or jurisdictions, and approval by one regulatory authority outside the United States and Europe does not ensure approval by
regulatory  authorities  in  other  countries  or  jurisdictions  or  by  the  FDA  or  regulatory  authorities  in  the  European  Union.  We  may  not  be  able  to  file  for
marketing approvals and may not receive necessary approvals to commercialize our products in any market. Marketing approvals in countries outside the
United States and Europe do not ensure pricing approvals in those countries or in any other countries, and marketing approvals and pricing approvals do not
ensure that reimbursement will be obtained.

39

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Side effects that appear following the launch of a drug on the market may result in the product being taken off the market or additional warnings being
added to the label despite having obtained all regulatory approvals.

A drug’s launch in the market may expose a large number of patients to potential risks associated with the treatment with a new pharmaceutical product.
Certain  side  effects,  which  may  not  have  been  identified  during  clinical  trials,  can  subsequently  appear.  For  these  reasons,  regulatory  agencies  require
companies  to  implement  post-approval  monitoring.  Depending  on  the  occurrence  of  serious  undesirable  effects,  the  agencies  may  require  that  we  or  a
collaboration  partner  of  ours  take  a  drug  off  the  market  temporarily  or  permanently,  even  if  it  is  effective  and  has  obtained  all  the  necessary  marketing
authorizations. Such an action would negatively impair our ability to generate revenue from such product and could more generally negatively affect our
ability to develop, obtain regulatory approval for, and commercialize our other product candidates and our reputation generally, each of which could have a
material adverse effect on our business and results of operations. In addition, if the product candidates we develop receive marketing authorization and we or
others  identify  undesirable  side  effects  caused  by  Lumoxiti  or  any  other  products  after  the  approval,  a  number  of  potentially  significant  negative
consequences  could  result,  including  that  regulatory  authorities  may  require  the  addition  of  labeling  statements,  such  as  a  “boxed”  warning  or  a
contraindication, we may be required to create a medication guide outlining the risks of such side effects for distribution to patients and our reputation may
suffer.

Lumoxiti and any other product candidate for which we obtain marketing approval will be subject to strict enforcement of post-marketing requirements
and  we  could  be  subject  to  substantial  penalties,  including  withdrawal  of  our  product  from  the  market,  if  we  fail  to  comply  with  all  regulatory
requirements or if we experience unanticipated problems with our product and product candidates, when and if any of them are approved.

Lumoxiti and any product candidate for which we obtain marketing approval, will be subject to continual requirements of and review by the FDA, EMA and
other regulatory authorities, including requirements relating to manufacturing processes, post-approval clinical data, labeling, advertising and promotional
activities  for  such  product.  These  requirements  include,  but  are  not  limited  to,  restrictions  governing  promotion  of  an  approved  product,  submissions  of
safety and other post-marketing information and reports, registration and listing requirements, cGMP requirements relating to manufacturing, quality control,
quality  assurance  and  corresponding  maintenance  of  records  and  documents,  and  requirements  regarding  the  distribution  of  samples  to  physicians  and
recordkeeping. In addition, 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, restrictions for specified age groups, warnings, precautions or contraindications or to the conditions of approval.

40

 
 
 
 
 
 
 
The  FDA  and  other  federal  and  state  agencies,  including  the  U.S.  Department  of  Justice,  or  DOJ,  closely  regulate  compliance  with  all  requirements
governing  prescription  products,  including  requirements  pertaining  to  marketing  and  promotion  of  products  in  accordance  with  the  provisions  of  the
approved labeling and manufacturing of products in accordance with cGMP requirements. The FDA and DOJ impose stringent restrictions on manufacturers’
communications regarding off-label use and if we do not market our products for their approved indications, we may be subject to enforcement action for off-
label  marketing.  Prescription  products  may  be  promoted  only  for  the  approved  indications  and  in  accordance  with  the  provisions  of  the  approved  label.
However, companies may also share truthful and not misleading information that is otherwise consistent with the labeling. Violations of such requirements
may lead to investigations alleging violations of the Food, Drug and Cosmetic Act and other statutes, including the False Claims Act and other federal and
state health care fraud and abuse laws as well as state consumer protection laws. Our failure to comply with all regulatory requirements, and later discovery
of previously unknown adverse events or other problems with our products, manufacturers or manufacturing processes, may yield various results, including:

·

·

·

·

·

·

·

·

·

·

·

·

litigation involving patients taking our products;

restrictions on such products, manufacturers or manufacturing processes;

restrictions on the labeling or marketing of a product;

restrictions on product distribution or use;

requirements to conduct post-marketing studies or clinical trials;

warning letters or untitled letters;

withdrawal of the products from the market;

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

recall of products;

fines, restitution or disgorgement of profits or revenues;

suspension or withdrawal of marketing approvals;

damage to relationships with any potential collaborators;

41

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
·

·

·

·

unfavorable press coverage and damage to our reputation;

refusal to permit the import or export of our products;

product seizure; or

injunctions or the imposition of civil or criminal penalties.

Non-compliance by us or any future collaborator with the FDA, EMA or other regulatory requirements regarding safety monitoring or pharmacovigilance,
and with requirements related to the development of products for the pediatric population, can also result in significant financial penalties. Similarly, failure
to comply with regulatory requirements regarding the protection of personal information can also lead to significant penalties and sanctions.

Our future growth depends, in part, on our ability to penetrate multiple markets, in which 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 Lumoxiti and our product candidates, if approved, in markets in Europe, the
United  States  and  other  countries  where  we  maintain  commercialization  rights.  If  we  commercialize  Lumoxiti  and  any  of  our  product  candidates,  if
approved, in multiple markets, we would be subject to additional risks and uncertainties, including:

·

·

·

·

·

·

·

·

·

·

foreign currency exchange rate fluctuations and currency controls;

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

potentially adverse and/or unexpected tax consequences, including penalties due to the failure of tax planning or due to the challenge by tax authorities
on the basis of transfer pricing and liabilities imposed from inconsistent enforcement;

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

different medical practices and customs in multiple countries affecting acceptance of drugs in the marketplace;

differing payor reimbursement regimes, governmental payors or patient self-pay systems and price controls;

tariffs, trade barriers, import or export licensing requirements or other restrictive actions;

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

workforce uncertainty in countries where labor unrest is common;

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

42

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
·

becoming subject to the different, complex and changing laws, regulations and court systems of multiple jurisdictions and compliance with a wide
variety of foreign laws, treaties and regulations.

These  and  other  risks  associated  with  international  operations  may  adversely  affect  our  ability  to  attain  or  maintain  profitable  operations.  Future  sales  of
Lumoxiti  or  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 affect milestone payments or royalties for Lumoxiti, monalizumab or any of our product candidates that are approved for
commercialization  in  the  future.  Should  any  of  these  risks  materialize,  this  could  have  a  material  adverse  effect  on  our  business,  prospects,  financial
condition and results of operations.

Even if our product candidates obtain regulatory approval, they will be subject to continuous regulatory review.

If marketing authorization is obtained for any of our product candidates, the candidate will remain subject to continuous review and therefore authorization
could be subsequently withdrawn or restricted. We will be subject to ongoing obligations and oversight by regulatory authorities, including adverse event
reporting requirements, marketing restrictions and, potentially, other post-marketing obligations, all of which may result in significant expense and limit our
ability to commercialize such products. For example, we will be responsible for the completion of an FDA required post-marketing trial of Lumoxiti.

If there are changes in the application of legislation or regulatory policies, or if problems are discovered with a product or our manufacture of a product, or if
we or one of our distributors, licensees or co-marketers fails to comply with regulatory requirements, the regulators could take various actions. These include
imposing fines on us, imposing restrictions on the product or its manufacture and requiring us to recall or remove the product from the market. The regulators
could  also  suspend  or  withdraw  our  marketing  authorizations,  requiring  us  to  conduct  additional  clinical  trials,  change  our  product  labeling  or  submit
additional  applications  for  marketing  authorization.  If  any  of  these  events  occurs,  our  ability  to  sell  such  product  may  be  impaired,  and  we  may  incur
substantial additional expense to comply with regulatory requirements, which could materially adversely affect our business, financial condition and results
of operations.

Even if one of our product candidates has orphan drug designation, we may not be able to obtain any benefit from such designation. Furthermore, if a
product is granted orphan drug exclusivity in the same indication for which we are developing lacutamab or our other product candidates that is granted
orphan drug designation, we may not be able to have our product candidate approved by the applicable regulatory authority for a significant period of
time.

Regulatory authorities in some jurisdictions, including the United States and Europe, may designate drugs for relatively small patient populations as orphan
drugs. Under the Orphan Drug Act, the FDA may designate a product candidate as an orphan drug if it is a drug intended to treat a rare disease or condition,
which is generally defined as a patient population of fewer than 200,000 individuals in the United States. In the European Union, the European Commission
may designate a product candidate as an orphan medicinal product if it is a medicine for the diagnosis, prevention or treatment of life-threatening or very
serious conditions that affects not more than five in 10,000 persons in the European Union, or it is unlikely that marketing of the medicine would generate
sufficient returns to justify the investment needed for its development. Generally, if a product candidate with an orphan drug designation receives the first
marketing approval for the indication for which it has such designation, the product is entitled to a period of marketing exclusivity, which, subject to certain
exceptions, precludes the FDA from approving the marketing application of another drug for the same indication for that time period or precludes the EMA,
and other national drug regulators in the European Union, from accepting the marketing application for another medicinal product for the same indication.
The applicable period is seven years in the United States and ten years in the European Union. The European Union period can be reduced to six years if a
product no longer meets the criteria for orphan drug designation or if the product is sufficiently profitable so that market exclusivity is no longer justified.
Orphan  drug  exclusivity  may  be  lost  in  the  United  States  if  the  FDA  determines  that  the  request  for  designation  was  materially  defective  or  if  the
manufacturer is unable to assure sufficient quantity of the product to meet the needs of patients with the rare disease or condition. The granting of a request
for orphan drug designation does not alter the standard regulatory requirements and process for obtaining marketing approval.

43

 
 
 
 
 
 
 
 
 
 
Lacutamab has been granted orphan drug designation for CTCL in Europe and in the United States and we may pursue orphan drug designation for another
product candidate that we may develop in the future in the United States and/or Europe. However, there is no assurance we will be able to receive orphan
drug designation for other product candidates that we may develop in the United States and/or Europe or for any other product candidate in any jurisdiction.
Even if we are successful in obtaining orphan drug designation, orphan drug status may not ensure that we have market exclusivity in a particular market.
Even  if  we  obtain  orphan  drug  exclusivity  for  any  of  our  product  candidates,  that  exclusivity  may  not  effectively  protect  the  product  from  competition
because exclusivity can be suspended under certain circumstances. In the United States, even after an orphan drug is approved, the FDA can subsequently
approve another drug for the same condition if the FDA concludes that the later drug is clinically superior in that it is shown to be safer, more effective or
makes a major contribution to patient care. In the European Union, orphan exclusivity will not prevent a marketing authorization being granted for a similar
medicinal product in the same indication if the new product is safer, more effective or otherwise clinically superior to the first product or if the marketing
authorization holder of the first product is unable to supply sufficient quantities of the product. In addition, if another product is granted marketing approval
and orphan drug exclusivity in the same indication for which we are developing a product candidate with orphan drug designation, we may not be able to
have our product candidate approved by the applicable regulatory authority for a significant period of time.

A fast track, breakthrough therapy or other designation by the FDA may not actually lead to a faster development.

We may seek fast track, breakthrough therapy or similar designation for our product candidates. If a product is intended for the treatment of a serious or life-
threatening condition and the product demonstrates the potential to address unmet medical need for this condition, the sponsor may apply for FDA fast track
designation. We have received fast track designation for lacutamab for the treatment of adult patients with relapsed or refractory Sézary syndrome who have
received at least two prior systemic therapies.

44

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Additionally, we may in the future seek a breakthrough therapy designation for some of our product candidates that reach the regulatory review process. A
breakthrough therapy is a drug candidate that is intended, alone or in combination with one or more other drugs, to treat a serious or life-threatening disease
or  condition,  and  that,  as  indicated  by  preliminary  clinical  evidence,  may  demonstrate  substantial  improvement  over  existing  therapies  on  one  or  more
clinically significant endpoints, such as substantial treatment effects observed early in clinical development. Drugs designated as breakthrough therapies by
the FDA are eligible for accelerated approval and increased interaction and communication with the FDA designed to expedite the development and review
process.

However,  these  designations  do  not  ensure  that  we  will  experience  a  faster  development  process,  review  or  approval  compared  to  conventional  FDA
procedures. In addition, the FDA may withdraw a designation if it believes that the designation is no longer supported by data from our clinical development
program. A designation alone does not guarantee qualification for the FDA’s priority review procedures.

Priority review designation by the FDA may not lead to a faster regulatory review or approval process and, in any event, does not assure FDA approval
of our product candidates.

If the FDA determines that a product candidate offers major advances in treatment or provides a treatment where no adequate therapy exists, the FDA may
designate the product candidate for priority review. A priority review designation means that the goal for the FDA to review an application is six months,
rather than the standard review period of ten months. We may request priority review for our product candidates. The FDA has broad discretion with respect
to whether or not to grant priority review status to a product candidate, so even if we believe a particular product candidate is eligible for such designation or
status,  the  FDA  may  decide  not  to  grant  it.  Moreover,  a  priority  review  designation  does  not  necessarily  mean  a  faster  regulatory  review  process  or
necessarily  confer  any  advantage  with  respect  to  approval  compared  to  conventional  FDA  procedures.  Receiving  priority  review  from  the  FDA  does  not
guarantee approval within the six-month review cycle or thereafter.

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

We are subject to other laws and regulations governing our international operations, including regulations administered by the governments of the United
States,  and  authorities  in  the  European  Union,  including  applicable  export  control  regulations,  economic  sanctions  on  countries  and  persons,  customs
requirements and currency exchange regulations, collectively referred to as the trade control laws.

45

 
 
 
 
 
 
 
 
 
The Foreign Corrupt Practices Act, or FCPA, prohibits any U.S. individual or business from paying, offering, authorizing payment or offering of anything of
value, directly or indirectly, to any foreign official, political party or candidate for the purpose of influencing any act or decision of the foreign entity in order
to assist the individual or business in obtaining or retaining business. The FCPA also obligates companies whose securities are listed in the United States to
comply  with  certain  accounting  provisions  requiring  the  company  to  maintain  books  and  records  that  accurately  and  fairly  reflect  all  transactions  of  the
corporation, including international subsidiaries, and to devise and maintain an adequate system of internal accounting controls for international operations.

Compliance with the FCPA is expensive and difficult, particularly in countries in which corruption is a recognized problem. In addition, the FCPA presents
particular challenges in the pharmaceutical industry, because, in many countries, hospitals are operated by the government, and doctors and other hospital
employees are considered foreign officials. Certain payments to hospitals in connection with clinical trials and other work have been deemed to be improper
payments to government officials and have led to FCPA enforcement actions.

French anti-corruption laws also prohibit acts of bribery and influence peddling:

·

·

·

·

·

·

·

·

·

·

Articles 433-1 1° and 432-11 1° of the French Criminal Code (bribery of domestic public officials);

Articles 433-1 2° and 432-11 2° of the French Criminal Code (influence peddling involving domestic public officials);

Article 434-9 of the French Criminal Code (bribery of domestic judicial staff);

Article 434-9-1 of the French Criminal Code (influence peddling involving domestic judicial staff);

Articles 445-1 and 445-2 of the French Criminal Code (bribery of private individuals);

Article 433-2 of the French Criminal Code (influence peddling involving private individuals);

Articles 435-1 and 435-3 of the French Criminal Code (bribery of foreign or international public officials);

Articles 435-7 and 435-9 of the French Criminal Code (bribery of foreign or international judicial staff);

Articles 435-2, 435-4, 435-8 and 435-10 of the French Criminal Code (active and passive influence peddling involving foreign or international public
officials and foreign or international judicial staff); and

French Law of December 9, 2017 on Transparency, the Fight Against Corruption and the Modernization of the Economy (Sapin 2 Law).

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

We  are  subject  to  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 arrangements
with such persons and third-party payors and our operations will expose us to broadly applicable fraud and abuse and other healthcare laws and regulations
that may constrain the business or financial arrangements and relationships through which we research, market, sell and distribute our products, if we obtain
marketing  authorization.  Restrictions  under  applicable  U.S.  federal,  state  and  foreign  healthcare  laws  and  regulations  include,  but  are  not  limited  to,  the
following:

·

·

·

·

·

the U.S. 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;

U.S. federal civil and criminal false claims laws and civil monetary penalties laws, including the civil False Claims Act, which impose criminal and
civil  penalties,  including  those  from  civil  whistle-blower  or  qui  tam  actions,  against  individuals  or  entities  for,  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.  Health  Insurance  Portability  and  Accountability  Act  of  1996,  or  HIPAA,  which  created  additional  federal  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 and its implementing regulations, which impose
certain requirements on covered entities and their business associates, including mandatory contractual terms, 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 CMS payments and other transfers of value provided to physicians and
teaching hospitals, and certain ownership and investment interests held by physicians or their immediate family members; and

47

 
 
 
 
 
 
 
 
 
 
·

analogous  state  or  foreign  laws  and  regulations,  such  as  state  anti-kickback  and  false  claims  laws,  including  the  French  “Bertrand  Law”,  French
Ordinance n°2017-49 of January 19, 2017, and the UK’s Bribery Act 2010, 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 the reporting of information relating to drug and
biologic  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.

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 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
criminal,  civil  or  administrative  sanctions,  including  exclusions  from  government  funded  healthcare  programs.  Should  any  of  these  risks  materialize,  this
could have a material adverse effect on our business, prospects, financial condition and results of operations.

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

We may collect, process, use or transfer personal information from individuals located in the European Union in connection with our business, including in
connection with conducting clinical trials in the European Union. Additionally, we intend to commercialize Lumoxiti, and any of our product candidates that
receive marketing approval, in the European Union. The collection and use of personal health data in the European Union are governed by the provisions of
the General Data Protection Regulation ((EU) 2016/679), or the GDPR. This legislation imposes requirements relating to having legal bases for processing
personal information relating to identifiable individuals and transferring such information outside of the European Economic Area, or EEA, including to the
United States, providing details to those individuals regarding the processing of their personal information, keeping personal information secure, having data
processing  agreements  with  third  parties  who  process  personal  information,  responding  to  individuals’  requests  to  exercise  their  rights  in  respect  of  their
personal  information,  reporting  security  breaches  involving  personal  data  to  the  competent  national  data  protection  authority  and  affected  individuals,
appointing data protection officers, conducting data protection impact assessments and record-keeping. 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. Failure to comply with the requirements of the GDPR and related national data protection laws of the member states of the European Union
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, prospects, financial condition and results of operations.

48

 
 
 
 
 
 
 
 
Risks Related to our Reliance on Third Parties

We depend upon our existing collaboration partners, AstraZeneca, Sanofi and other third parties, and may depend upon future collaboration partners to
commit to the research, development, manufacturing and marketing of our drugs.

We  have  significant  collaborations  with  AstraZeneca  for  the  commercialization  of  Lumoxiti  and  the  development  of  monalizumab,  IPH5201  and  other
product candidates. We also collaborate with Sanofi for the development of IPH61, and we may enter into additional collaborations for other of our product
candidates or technologies in development. We cannot control the timing or quantity of resources that our existing or future collaborators will dedicate to
research, preclinical and clinical development, manufacturing or marketing of our products. Our collaborators may not perform their obligations according to
our expectations or standards of quality. Our collaborators could terminate our existing agreements for a number of reasons, including that they may have
other,  higher  priority  products  in  development  or  because  our  partnered  programs  may  no  longer  be  a  priority  for  them.  If  any  of  our  collaboration
agreements were to be terminated, we could encounter significant delays in developing our product candidates, lose the opportunity to earn any revenues we
expected to generate under such agreements, incur unforeseen costs, and suffer damage to the reputation of our product, product candidates and as a company
generally.

In order to optimize the launch and market penetration of certain of our future product candidates, we may enter into distribution and marketing agreements
with  pharmaceutical  industry  leaders.  For  these  product  candidates,  we  would  not  market  our  products  alone  once  they  have  obtained  marketing
authorization. The risks inherent in entry into these contracts are as follows:

·

·

the negotiation and execution of these agreements is a long process that may not result in an agreement being signed or that can delay the development
or commercialization of the product candidate concerned;

these agreements are subject to cancellation or non-renewal by our collaborators, or may not be fully complied with by our collaborators;

49

 
 
 
 
 
 
 
 
 
·

·

in the case of a license granted by us, we lose control of the development of the product candidate licensed; in such cases we would have only limited
control over the means and resources allocated by our partner for the commercialization of our product; and

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

Should any of these risks materialize, or should we fail to find suitable collaborators, this could have a material adverse effect on our business, prospects,
financial condition and results of operations.

The  late-stage  development  and  marketing  of  our  product  candidates  may  partially  depend  on  our  ability  to  establish  collaborations  with  major
biopharmaceutical companies.

In order to develop and market some of our product candidates, we rely on collaboration, research and license agreements with pharmaceutical companies to
assist us in the development of product candidates and the financing of their development. For our most advanced clinical product candidate, monalizumab,
we  entered  into  an  agreement  with  AstraZeneca,  in  part  because  of  their  late-stage  development  and  marketing  capabilities.  As  we  identify  new  product
candidates, we will determine the appropriate strategy for development and marketing, which may result in the need to establish collaborations with major
biopharmaceutical companies. We may also enter into agreements with institutions and universities to participate in our other research programs and to share
intellectual property rights.

We may fail to find collaboration partners and to sign new agreements for our other product candidates and programs. The competition for partners is intense,
and the negotiation process is time-consuming and complex. Any new collaboration may be on terms that are not optimal for us, and we may not be able to
maintain any new collaboration if, for example, development or approval of a product candidate is delayed, sales of an approved product candidate do not
meet  expectations  or  the  collaborator  terminates  the  collaboration.  Any  such  collaboration,  or  other  strategic  transaction,  may  require  us  to  incur  non-
recurring  or  other  charges,  increase  our  near-  and  long-term  expenditures  and  pose  significant  integration  or  implementation  challenges  or  disrupt  our
management or business. These transactions would entail numerous operational and financial risks, including exposure to unknown liabilities, disruption of
our business and diversion of our management’s time and attention in order to manage a collaboration or develop acquired products, product candidates or
technologies,  incurrence  of  substantial  debt  or  dilutive  issuances  of  equity  securities  to  pay  transaction  consideration  or  costs,  higher  than  expected
collaboration, acquisition or integration costs, write-downs of assets or goodwill or impairment charges, increased amortization expenses, difficulty and cost
in  facilitating  the  collaboration  or  combining  the  operations  and  personnel  of  any  acquired  business,  impairment  of  relationships  with  key  suppliers,
manufacturers or customers of any acquired business due to changes in management and ownership and the inability to retain key employees of any acquired
business. Accordingly, although there can be no assurance that we will undertake or successfully complete any transactions of the nature described above,
any  transactions  that  we  do  complete  may  be  subject  to  the  foregoing  or  other  risks  and  have  a  material  and  adverse  effect  on  our  business,  financial
condition,  results  of  operations  and  prospects.  Conversely,  any  failure  to  enter  any  additional  collaboration  or  other  strategic  transaction  that  would  be
beneficial to us could delay the development and potential commercialization of our product candidates and have a negative impact on the competitiveness of
any product candidate that reaches market.

50

 
 
 
 
 
 
 
 
 
We rely on third parties to supply key materials used in our research and development, to provide services to us and to assist with clinical trials.

We make considerable use of third-party suppliers for the key materials used in our business. The failure of third-party suppliers to comply with regulatory
standards  could  result  in  the  imposition  of  sanctions  on  us.  These  sanctions  could  include  fines,  injunctions,  civil  penalties,  refusal  by  regulatory
organizations to grant approval to conduct clinical trials or marketing authorization for our products, delays, suspension or withdrawal of approvals, license
revocation,  seizure  or  recalls  of  our  products,  operating  restrictions  and  legal  proceedings.  Furthermore,  the  presence  of  non-conformities,  as  detected  in
regulatory  toxicology  studies,  could  result  in  delays  in  the  development  of  one  or  more  of  our  product  candidates  and  would  require  further  tests  to  be
financed. Although we are involved in establishing the protocols for the production of these materials, we do not control all the stages of production and
cannot guarantee that the third parties will fulfil their contractual and regulatory obligations. In particular, a partner’s failure to comply with protocols or
regulatory constraints, or repeated delays by a partner, could compromise the development of our products or limit its liability. Such events could also inflate
the product development costs incurred by us.

We  also  use  third  parties  to  provide  certain  services  such  as  scientific,  medical  or  strategic  consultancy  services.  These  service  providers  are  generally
selected  for  their  specific  expertise,  as  is  the  case  with  the  academic  partners  with  whom  we  collaborate.  To  build  and  maintain  such  a  network  under
acceptable terms, we face intense competition. Such external collaborators may terminate, at any time, their involvement. We can exert only limited control
over their activities. We may not be able to obtain the intellectual property rights to the product candidates or technologies developed under collaboration,
research and license agreements under acceptable terms or at all. Moreover, our scientific collaborators may assert intellectual property rights or other rights
beyond the terms of their engagement.

Finally,  we  use  third-party  investigators  to  assist  with  conducting  clinical  trials.  All  clinical  trials  are  subject  to  strict  regulations  and  quality  standards.
Should any of these risks materialize, this could have a material adverse effect on our business, prospects, financial condition and results of operations.

We  do  not  and  will  not  have  access  to  all  information  regarding  our  product  candidates  that  are  subject  to  collaboration  and  license  agreements.
Consequently, our ability to inform our shareholders about the status of product candidates that are subject to these agreements, and our ability to make
business and operational decisions, may be limited.

We do not and will not have access to all information regarding our product candidates that are subject to our license and collaboration agreements with
AstraZeneca, Sanofi and other third parties, including potentially material information about clinical trial design, execution and timing, safety and efficacy,
clinical trial results, regulatory affairs, manufacturing, marketing and other areas known by our collaborators. In addition, we have confidentiality obligations
under our collaboration and license agreements. Therefore, our ability to keep our shareholders informed about the status of product candidates subject to
such agreements will be limited by the degree to which our collaborators keep us informed and allow us to disclose information to the public or provide such
information to the public themselves. If our collaborators do not inform us about our product candidates subject to agreements with them, we may make
operational  and  investment  decisions  that  we  would  not  have  made  had  we  been  fully  informed,  which  may  have  an  adverse  impact  on  our  business,
prospects, financial condition and results of operations.

51

 
 
 
 
 
 
 
 
 
Risks Related to the Manufacture of Lumoxiti and Our Product Candidates

We have no manufacturing capabilities and rely on third-party manufacturers for Lumoxiti and our product candidates.

Our product candidates that are tested during our preclinical and clinical trials are manufactured by third parties. We have no production capabilities and rely
on third parties to manufacture our products.

This strategy means that we do not directly control certain key aspects of our product development, such as:

·

·

·

·

the quality of the product manufactured;

the delivery times for drugs for a given clinical trial;

the clinical and commercial quantities that can be supplied; and

compliance with applicable laws and regulations.

Our reliance on third-party manufacturers creates risks that may not exist if we had our own manufacturing capabilities. These risks include:

·

·

·

·

·

failure of third-party manufacturers to comply with regulatory and quality-control standards;

production of insufficient quantities;

damage during transport and/or storage of our product candidates;

breach of agreements by third-party manufacturers; and

termination or non-renewal of the agreements for reasons beyond our control.

Should our third-party manufacturers breach their obligations or should we fail to renew our contracts with them, we cannot guarantee that we will be able to
find  new  suppliers  within  a  timeframe  and  under  conditions  that  would  not  be  detrimental.  We  could  also  be  faced  with  delays  or  interruptions  in  our
supplies, which could result in a delay in the clinical trials and, ultimately, a delay in the commercialization of the product candidates that we are developing
or  a  loss  of  product  sales.  For  example,  manufacturing  issues,  leading  to  out-of-specification  product,  can  occur  during  a  manufacturing  campaign  at  the
CMO in charge of the production of our product candidates.

Reproducing a batch of product is a lengthy and costly process and sometimes can lead to drug shortage that can in turn lead to a delay in the development of
the  candidate,  or  even  an  early  stop  of  a  clinical  trial.  This  happened  in  the  early  clinical  development  of  lacutamab  and  led  to  the  decision  to  limit  the
number of patients in order to ensure drug supply for treated patients in the Phase I clinical trial.

In November 2019, Impletio Wirkstoffabfüllung GmbH (formerly known as Rentschler Fill Solutions GmbH), the subcontractor in charge of the fill-and-
finish  manufacturing  operations  of  lacutamab,  unilaterally  decided  to  withdraw  the  certificates  of  conformance  of  all  clinical  batches  produced  at  their
facilities,  including  the  lacutamab  batch  used  for  the  TELLOMAK  Phase  II  clinical  trial  assessing  lacutamab  in  multiple  indications.  Impletio
Wirkstoffabfüllung  GmbH  decided  to  withdraw  the  certificates  of  conformance  even  though  the  compliance  of  its  manufacturing  site  with  Good
Manufacturing Practices has been confirmed by two on-site inspections performed by the Austrian Health Agency before and after we began to work with
them.

The transfer of the manufacturing process to another contract manufacturing organization will be lengthy and we will not be able to receive new clinical
batches before the second half of 2020. As a consequence and after discussions with the regulatory agencies of the countries in which the TELLOMAK trial
is being conducted in a number of countries, the TELLOMAK trial has been placed on partial or full hold in the U.S., Spain, Germany and Italy. See “Item
4.B–Business  Overview—Lacutamab,  A  Tumor  Targeting  Anti-KIR3DL2  Antibody—Clinical  Development  of  Lacutamab—Phase  II  Clinical  Trial
(TELLOMAK).”

Should any of these risks materialize, this could have a material adverse effect on our business, prospects, financial condition and results of operations.

We  are  reliant  upon  third  parties  to  manufacture  and  supply  components  of  certain  substances  necessary  to  manufacture  Lumoxiti  and  our  product
candidates.

We do not currently independently conduct manufacturing activities for Lumoxiti or our product candidates in development, and we are reliant on several
third-party CMOs for the manufacture and supply of components and substances for all of the product candidates we are developing. In addition, certain
component materials are currently available from a single supplier, or a small number of suppliers. We cannot be sure that these suppliers will remain in
business, or that they will not be purchased by one of our competitors or another company that is not interested in continuing to manufacture these materials
for us. We cannot assure you that, if required, we will be able to identify alternate sources with the desired scale and capability and establish relationships
with such sources. A loss of any CMO or component supplier and delay in establishing a replacement could delay our clinical development and regulatory
approval process.

Manufacturing facilities and clinical trial sites are subject to significant government regulations and approvals and if our or our partners’ third-party
manufacturers fail to comply with these regulations or maintain these approvals, our business could be materially harmed.

Our  third-party  manufacturers  are  subject  to  ongoing  regulation  and  periodic  inspection  by  national  authorities,  including  the  EMA,  FDA  and  other
regulatory bodies to ensure compliance with cGMP, when producing batches of Lumoxiti and our product candidates for clinical trials. CROs and other third-
party research organizations must also comply with Good Laboratory Practices (GLP) when carrying out regulatory toxicology studies. Any failure to follow
and document our or their adherence to such GMP and GLP 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.

53

 
 
 
 
 
 
 
 
 
 
 
Failure  to  comply  with  applicable  regulations  could  also  result  in  national  authorities,  the  EMA,  FDA  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 authorization in Europe, the United States or
elsewhere, our suppliers will have to pass an inspection by the applicable regulatory agencies. We are dependent on our suppliers’ cooperation and ability to
pass such inspections, and the inspections and any necessary remediation may be costly. Failure to pass such inspections by us or any of our suppliers would
affect our ability to commercialize Lumoxiti or our product candidates in Europe, the United States or elsewhere. Should any of these risks materialize, this
could  have  a  material  adverse  effect  on  our  business,  prospects,  financial  condition  and  results  of  operations.  For  example,  in  November  2019,  Impletio
Wirkstoffabfüllung GmbH (formerly known as Rentschler Fill Solutions GmbH), the subcontractor in charge of the fill-and-finish manufacturing operations
of lacutamab unilaterally decided to withdraw the certificates of conformance of all clinical batches produced at their facilities, including the lacutamab batch
used for the TELLOMAK Phase II clinical trial assessing lacutamab in multiple indications, which resulted in partial or full holds in a number of countries.
See  “Item  4.B–Business  Overview—Lacutamab,  A  Tumor  Targeting  Anti-KIR3DL2  Antibody—Clinical  Development  of  Lacutamab—Phase  II  Clinical
Trial (TELLOMAK).”

54

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Our production costs may be higher than we currently estimate.

Lumoxiti and our product candidates are manufactured 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 were 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;

unavailable qualified personnel;

power failure of extended duration; and

logistical error.

Should any of these risks materialize, this could have a material adverse effect our business, prospects, financial condition and results of operations.

We may use hazardous chemicals and biological materials in our business and 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, biological and radioactive materials. We
cannot  eliminate  the  risk  of  accidental  contamination  or  discharge  and  any  resultant  injury  from  these  materials.  We  also  handle  genetically  recombined
material, genetically modified species and pathological biological samples. Consequently, in France and in the jurisdictions where we conduct clinical trials,
we are subject to environment and safety laws and regulations governing the use, storage, handling, discharge and disposal of hazardous materials, including
chemical and biological products and radioactive materials. We impose preventive and protective measures for the protection of our workforce and waste
control management in accordance with applicable laws, including part four of the French Labor Code, relating to occupational health and safety.

In France, we are required to comply with a number of national, regional and local legislative or regulatory provisions regarding radiation and hazardous
materials,  including  specific  regulations  regarding  the  use,  handling  and  storage  of  radioactive  materials  and  the  potential  exposure  of  employees  to
hazardous  materials  and  radiation.  We  must  also  comply  with  French  regulations  concerning  the  use  and  handling  of  genetically  modified  organisms,  or
GMOs, in confined spaces.

If  we  fail  to  comply  with  applicable  regulations,  we  could  be  subject  to  fines  and  may  have  to  suspend  all  or  part  of  our  operations.  Compliance  with
environmental, health and safety regulations involves additional costs, and we may have to incur significant costs to comply with future laws and regulations
in  relevant  jurisdictions.  Compliance  with  environmental  laws  and  regulations  could  require  us  to  purchase  equipment,  modify  facilities  and  undertake
considerable expenses. We could be liable for any inadvertent contamination, injury or damage, which could negatively affect its business, although we have
subscribed to an insurance policy covering certain risks inherent to its business.

Risks Related to Our Organization and Operations

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

Our strategy involves continuing to grow our business internally. However, we may also grow externally through selective acquisitions of complementary
products and technologies, or of companies with such assets, although no such plan is currently contemplated. As our development progresses, we expect to
experience  significant  growth  in  the  number  of  our  employees  and  the  scope  of  our  operations,  particularly  in  the  areas  of  research,  drug  development,
regulatory affairs and sales, marketing and distribution for our approved product, Lumoxiti. To manage our anticipated future growth, we must continue to
implement  and  improve  our  managerial,  operational  and  financial  systems,  expand  our  facilities  and  continue  to  recruit  and  train  additional  qualified
personnel. Due to our limited financial resources and the limited experience of our management team in managing a company with such anticipated growth,
we may not be able to effectively manage the expansion of our operations or recruit and train additional qualified personnel. This risk is compounded by the
fact that we are located in Marseille, France and compete with other locations that potential recruits may find more attractive.

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 internal or external growth. We may not be able to effectively manage the expansion of our operations which may result in weaknesses in our
infrastructure, give rise to operational errors, loss of business opportunities, loss of employees and reduced productivity among remaining employees. Our
expected growth could require significant capital expenditures and may divert financial resources from other projects, such as the development of existing
and additional product candidates. If our management is unable to effectively manage our expected growth, our expenses may increase more than expected,
our ability to generate and/or grow revenue could be reduced and we may not be able to implement our business strategy.

If we were to acquire assets or companies, the success of such an acquisition would depend on our capacity to carry out such acquisitions and to integrate
such assets or companies into our existing operations. The implementation of such a strategy could impose significant constraints, including:

·

·

·

human resources: recruiting, integrating, training, managing, motivating and retaining a growing number of employees;

financial  and  management  system  resources:  identification  and  management  of  appropriate  financing  and  management  of  our  financial  reporting
systems; and

infrastructure: expansion or transfer of our laboratories or the development of our information technology system.

In 2019, we initiated a significant upgrade of our information system to support our development, starting with the implementation of an Enterprise Resource
Planning system to equip our company with robust and standard tools and reinforce the reliability of our financial operations and information. Such a project
is transformative and involves a significant amount of human resources and presents risks, such as (i) the risk of delays in the operations during the first
months of implementation, (ii) the risk of loss of data and/or quality of data during the migration process and (iii) the risk that our employees do not fully
adhere to such new organizations and information systems (the so-called “change management risk”).

56

 
 
 
 
 
 
 
 
 
 
 
 
If we are unable to manage internal growth or have difficulty integrating any acquisitions, it could have a material adverse effect on our business, prospects,
financial condition and results of operations.

We will need to hire new employees and expand our use of service providers.

As  of  December  31,  2019,  we  had  235  employees.  As  our  development  and  commercialization  plans  and  strategies  develop,  we  must  add  a  significant
number of additional managerial, operational, sales, marketing, financial and other personnel.

We currently rely, and for the foreseeable future will continue to rely, in part on certain independent organizations, advisors and consultants to provide certain
services. There can be no assurance that the services of these independent organizations, advisors and consultants will continue to be available to us on a
timely basis when needed, or that we can find qualified replacements. In addition, if we are unable to effectively manage our outsourced activities or if the
quality or accuracy of the services provided by consultants is compromised for any reason, our clinical trials may be extended, delayed, or terminated, and
we may not be able to obtain regulatory approval of our product candidates or otherwise advance our business. There can be no assurance that we will be
able to manage our existing consultants or find other competent outside contractors and consultants on economically reasonable terms, if at all.

If we are not able to effectively expand our organization by hiring new employees and expanding our groups of consultants and contractors, we may not be
able  to  successfully  implement  the  tasks  necessary  to  further  develop  and  commercialize  Lumoxiti  and  our  product  candidates  and,  accordingly,  may  not
achieve our research, development and commercialization goals.

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

Our ability to retain key persons in our organization and to recruit qualified personnel is crucial for our success. In particular, our success depends heavily on
its ability to retain key people in our organization, including key scientific and medical personnel.

Should we be unable to retain the individuals who form our team of key managers and key scientific advisors, it could have a material adverse effect on our
business and development and could consequently affect our business, prospects, financial condition and results of operations.

We will need to recruit qualified scientific and medical personnel to carry out our clinical trials and expand into new areas that require specialized skills, such
as regulatory matters, marketing and manufacturing. We compete with other companies, research organizations and academic institutions in recruiting and
retaining highly qualified scientific, technical and management personnel. Competition for such personnel is very intense in the biopharmaceutical field and
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. Should any of these risks materialize, this could have a material adverse effect on our business, prospects, financial condition and results of
operations.

57

 
 
 
 
 
 
 
 
 
 
 
 
Our business may be exposed to foreign exchange risks.

We incur some of our expenses, and derive certain of our revenues, in currencies other than the euro. In particular, as we expand our operations and conduct
additional clinical trials in the United States, we will incur additional expenses in U.S. dollars. As a result, we are exposed to foreign currency exchange risk
as our results of operations and cash flows are subject to fluctuations in foreign currency exchange rates.

We currently do not engage in hedging transactions to protect against uncertainty in future exchange rates between particular foreign currencies and the euro.
Therefore,  an  unfavorable  change  in  the  value  of  the  euro  against  the  U.S.  dollar  could  have  a  negative  impact  on  our  revenue  and  earnings  growth.  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. The ADSs being offered in the U.S. offering are quoted in U.S. dollars on Nasdaq, while our ordinary shares trade in euro on
Euronext Paris. Our financial statements are prepared in euro. 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.

Under our license and collaboration agreements with AstraZeneca, the payments we receive are in U.S. dollars. In the future, we could generate part of our
sales in the United States and part in Europe and could therefore be subject to an unfavorable euro/dollar exchange rate. Therefore, for example, an increase
in the value of the euro against the U.S. dollar could be expected to have a negative impact on our revenue and earnings growth as U.S. dollar revenue and
earnings, if any, would be translated into euro at a reduced value. We could also sign contracts denominated in other currencies, which would increase our
exposure to currency risk. In accordance with our business decisions, our exposure to this type of risk could change depending on:

·

·

·

·

the currencies in which we receive our revenues;

the currencies chosen when agreements are signed, such as licensing agreements, or co-marketing or co- development agreements;

the location of clinical trials on product candidates; and

our policy for insurance cover.

At  present,  we  have  not  put  any  specific  hedging  arrangements  in  place  to  address  these  risks.  Should  any  of  these  risks  materialize,  this  could  have  a
material adverse effect on our business, prospects, financial condition and results of operations.

58

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

Given  that  we  develop  therapeutic  products  intended  to  be  tested  on  humans  and  used  to  treat  humans,  the  risk  that  we  may  be  sued  on  product  liability
claims  is  inherent  in  our  business.  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.  For  example,  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. 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, may be
forced to limit or forgo further commercialization of the affected products and may suffer damage to our reputation.

Although the clinical trial process is designed to identify and assess potential side effects, it is always possible that a drug, even after regulatory approval,
may exhibit unforeseen side effects. If any of our product candidates were to cause adverse side effects during clinical trials or after approval of the product
candidate, we may be exposed to substantial liabilities. Physicians and patients may not comply with any warnings that identify known potential adverse
effects and patients who should not use Lumoxiti or our product candidates.

We have obtained liability insurance coverage for each of our clinical trials in compliance with local legislation and rules. In the United States, our aggregate
insurance coverage for our ongoing clinical trials is €10.0 million in the aggregate. Our insurance coverage may not be sufficient to cover any expenses or
losses  we  may  suffer.  Moreover,  insurance  coverage  is  becoming  increasingly  expensive,  and,  in  the  future,  we  may  not  be  able  to  maintain  insurance
coverage at a reasonable cost or in sufficient amounts to protect us against losses due to liability. On occasion, large judgments have been awarded in class
action lawsuits based on drugs that had unanticipated side effects. The cost of any product liability litigation or other proceedings, even if resolved in our
favor,  could  be  substantial.  A  successful  product  liability  claim,  or  series  of  claims,  brought  against  us  could  cause  our  share  price  to  decline  and,  if
judgments exceed our insurance coverage, could decrease our cash and adversely affect our business.

To date, we have obtained product liability insurance with a coverage amount of €10 million per year. Our product liability insurance will need to be adjusted
in connection with the commercial sales of Lumoxiti and our product candidates, and may be unavailable in meaningful amounts or at a reasonable cost. If
we are the subject of a successful product liability claim that exceeds the limits of any insurance coverage we obtain, we would incur substantial charges that
would adversely affect our earnings and require the commitment of capital resources that might otherwise be available for the development and commercial
launch  of  our  product  programs.  Should  any  of  these  risks  materialize,  this  could  have  a  material  adverse  effect  on  our  business,  prospects,  financial
condition and results of operations.

59

 
 
  
 
 
 
 
 
There are material weaknesses and significant deficiencies in our internal controls over financial reporting and if we are unable to maintain effective
internal  controls  over  financial  reporting,  the  accuracy  and  timeliness  of  our  financial  reporting  may  be  adversely  affected,  which  could  hurt  our
business, lessen investor confidence and depress the market price of our securities.

We must maintain effective internal control over financial reporting in order to accurately and timely report our results of operations and financial condition.
In addition, as a public company listed in the United States, the Sarbanes-Oxley Act will require, among other things, that we assess the effectiveness of our
internal control over financial reporting at the end of each fiscal year starting year ended December 31, 2020. However, our independent registered public
accounting firm will not be required to attest to the effectiveness of our internal controls over financial reporting for so long as we are an “emerging growth
company,”  which  may  be  up  to  five  fiscal  years  following  the  date  of  the  October  2019  public  global  offering.  An  independent  assessment  of  the
effectiveness of our internal controls over financial reporting could detect problems that our management’s assessment might not.

During the audit of our consolidated financial statements as of and for the years ended December 31, 2019, we identified material weaknesses in our internal
control over financial reporting. A company’s internal control over financial reporting is a process designed by, or under the supervision of, a company’s
principal executive and principal financial officers, or persons performing similar functions, and effected by a company’s executive board, management and
other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with
generally  accepted  accounting  principles.  Under  standards  established  by  the  Public  Company  Accounting  Oversight  Board,  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 in
our annual or interim financial statements will not be prevented or detected and corrected on a timely basis.

In the course of auditing the consolidated financial statements as of and for the year ended December 3 1, 2019, several material weaknesses in our internal
control over financial reporting were identified. The material weaknesses related to (i) the accounting for subcontracting clinical costs for which there was
insufficient control on the input data coming from clinical studies and used in assessing their advancement (input data mainly includes expected termination
date of the study, overall budget and/or number of patient visits),  and (ii) the recognition of the revenue from our collaboration and licensing agreement with
AstraZeneca  on  monalizumab  for  which  there  was  insufficient  review  of  the  calculation  of  the  transaction  price  and  percentage  of  completion  of  costs
incurred.  Errors  not  detected  in  relation  to  topic  (i)  have  led  to  incorrect  amounts  of  R&D  expenses  for  the  year  ended  December  31,  2019,  which  were
subsequently  corrected  prior  to  the  issuance  of  our  audited  financial  statements.  The  material  weakness  in  relation  to  topic  (ii)  has  led  to  a  material
misstatement of revenue for the year ended December 31, 2019, which was subsequently corrected prior to the issuance of our audited financial statements.
In  addition  our  information  system,  supporting  the  production  of  our  financial  information,  also  showed  material  weaknesses  in  terms  of  "general  IT
controls" (GITC) related to the management of access rights, including segregation of duties and change management.

60

 
 
 
 
 
 
 
We  are  in  the  process  of  implementing  measures  aimed  at  remedying  such  weaknesses.  In  particular,  in  2019,  we  initiated  a  significant  upgrade  of  our
information  system  to  support  our  development,  starting  with  the  implementation  of  an  Enterprise  Resource  Planning  system  to  equip  our  company  with
robust and standard tools and reinforce the reliability of our financial operations and information. In addition, we intend to allocate further human resources
to our information systems and internal control departments in 2020.

We have taken and are taking steps to remediate the foregoing weaknesses and deficiencies. However, if we do not successfully remediate these issues or if
we fail to design and operate effective internal controls in the future, it could result in material misstatements in our financial statements, result in the loss of
investor confidence in the reliability of our financial statements and subject us to regulatory scrutiny and sanctions, which in turn could harm the market
value of our ordinary shares and ADSs.

The rules governing the standards must be met for our management to assess our internal control over financial reporting pursuant to Section 404 of the
Sarbanes-Oxley Act are complex and require significant documentation, testing and possible remediation. These stringent standards require that our audit
committee be advised and regularly updated on management’s review of internal control over financial reporting. We have begun the process of designing,
implementing, and testing the internal control over financial reporting required to comply with this obligation. This process is time-consuming, costly, and
complicated.  Our  management  may  not  be  able  to  effectively  and  timely  implement  controls  and  procedures  that  adequately  respond  to  the  increased
regulatory compliance and reporting requirements that are or will be applicable to us as a public company listed in the United States. If we fail to staff our
accounting and finance function adequately or maintain internal control over financial reporting adequate to meet the demands that are or will be placed upon
us as a public company listed in the United States, our business and reputation may be harmed and the price of our ordinary shares and ADSs may decline. In
addition, undetected material weaknesses in our internal control over financial reporting could lead to restatements of financial statements and require us to
incur the expense of remediation. Any of these developments could result in investor perceptions of us being adversely affected, which could cause a decline
in the market price of our securities.

61

 
 
 
 
 
 
 
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.

We have implemented a security policy that are both intended to secure our data against impermissible access and to preserve the integrity and confidentiality
of the data. Despite the implementation of such security measures, including a cybersecurity program under development since 2019, 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, telecommunication and electrical failures, and other sources. Moreover, part of our information system is “cloud”-based and thus is not fully
under our control.

In addition, our research and development facility and headquarters in Luminy, France is located in an area that may be more susceptible to wildfires. If our
facility or computer systems are damaged by fire despite the fire prevention and data archiving measures we have put in place, we could suffer financial
losses and delays in our operations.

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,
including penalties under data privacy laws such as the GDPR and other regulations, and the further development of our product candidates could be delayed.
Should any of these risks materialize, this could have a material adverse effect on our business, prospects, financial condition and results of operations.

Our employees may engage in misconduct or other improper activities, including violating applicable regulatory standards and requirements, engaging
in insider trading or violate the terms of their confidentiality agreements, 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  national  authorities,  the  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, Europe and elsewhere, 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 a Code of Ethics that applies to all employees and consultants,
and other policies and charters, 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.

62

 
 
 
 
 
 
 
 
 
In order to protect our proprietary technology and processes, we rely in part on confidentiality agreements with our partners, employees, consultants, outside
scientific collaborators and sponsored researchers, and other advisors. These agreements may not effectively prevent disclosure of confidential information
and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. Costly and time-consuming litigation could be
necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could adversely affect our
competitive business position. Should any of these risks materialize, this could have a material adverse effect on our business, prospects, financial condition
and results of operations.

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

Although our current strategy involves continuing to grow our business internally, we may grow externally through selective acquisitions of complementary
products and technologies, or of companies with such assets. If such acquisitions were to become necessary or attractive 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 under favorable conditions, and could be led to finance these acquisitions using cash that could be allocated to
other purposes in the context of existing operations. We may encounter numerous difficulties in developing, manufacturing and marketing any new products
resulting from an 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, which could have a material adverse effect on our business, financial
conditions, earnings and prospects.

Risks Related to Intellectual Property Rights

Our ability to compete may be adversely affected if we do not adequately obtain, maintain, protect and enforce our intellectual property or proprietary
rights, or if the scope of intellectual property protection we obtain is not sufficiently broad.

Our  success  depends,  in  large  part,  on  our  ability  to  obtain  and  maintain  patent  and  other  intellectual  property  protection  in  the  United  States  and  other
countries with respect to Lumoxiti and our product candidates. However, we may not be able to obtain, maintain or enforce our patents and other intellectual
property rights which could affect our ability to compete effectively. For example, we cannot guarantee:

·

·

that we will file all necessary or desirable patent applications or that we will obtain the patents that we have applied for and that are under review;

that  we  will  be  able  to  develop  new  patentable  product  candidates  or  technologies  or  obtain  patents  to  protect  such  new  product  candidates  or
technologies;

63

 
 
 
 
 
 
 
 
 
 
 
·

·

·

·

that  we  or  our  licensing  or  collaboration  partners  were  the  first  to  make  the  product  candidates  or  technologies  covered  by  the  issued  patents  or
pending patent applications that we license or own;

that we will be able to obtain sufficient rights to all necessary or desirable patents or other intellectual property rights, whether at all or on reasonable
terms;

that the scope of any issued patents that we own or license will be broad enough to protect Lumoxiti or our product candidates or effectively prevent
others from commercializing competitive technologies and product candidates; and

that there is no risk of our owned and licensed patents being challenged, invalidated or circumvented by a third-party.

The  patent  prosecution  process  is  expensive,  time-consuming,  and  complex,  and  we  may  not  be  able  to  file,  prosecute,  maintain,  enforce,  or  license  all
necessary or desirable patent applications at a reasonable cost or in a timely manner. For example, we do not intend to systematically file, maintain, prosecute
and  defend  patents  on  Lumoxiti  and  our  product  candidates  in  all  countries.  Consequently,  we  may  not  be  able  to  prevent  third  parties  from  exploiting
products that are the same as or similar to our products and product candidates in countries in which we do not obtain patent protection, or from selling or
importing such products in and into the countries in which we do have patent protection. It is also possible that we will fail to identify patentable aspects of
our research and development output in time to obtain patent protection. Although we enter into confidentiality agreements with parties who have access to
confidential  or  patentable  aspects  of  our  research  and  development  output,  such  as  our  employees,  consultants,  CROs,  outside  scientific  collaborators,
sponsored  researchers,  and  other  advisors,  any  of  these  parties  may  breach  the  agreements  and  disclose  such  output  before  a  patent  application  is  filed,
thereby  jeopardizing  our  ability  to  seek  patent  protection.  Given  the  amount  of  time  required  for  the  development,  testing  and  regulatory  review  of  new
product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our intellectual
property  may  not  provide  us  with  sufficient  rights  to  exclude  others  from  commercializing  product  candidates  similar  or  identical  to  ours.  In  addition,  in
some circumstances, we may not have the right to control the preparation, filing, prosecution, maintenance, enforcement and defense of patents and patent
applications covering technology that we license to or from third parties. For example, pursuant to our license agreement with AstraZeneca for monalizumab,
AstraZeneca retains control of such activities for certain patents that we license to it under the agreement and patents that arise under the collaboration. We
cannot be certain that these patents and patent applications will be prepared, filed, prosecuted, maintained, enforced, and defended in a manner consistent
with the best interest of our business. If any third-party that controls our patents and patent applications fails to maintain our patents or such third-party loses
rights to our patents or patent applications, our rights to those patents and underlying technology may be reduced or eliminated and our right to develop and
commercialize our product candidates that are subject to such rights could be adversely affected.

Moreover, some of our patents and patent applications are, and may in the future be, co-owned with third parties. If we are unable to obtain an exclusive
license to any such third-party co-owners’ interest in such patents or patent applications, such co-owners may be able to license their rights to other third
parties, including our competitors, and our competitors could market competing products and technology. We may also need the cooperation of any such co-
owners of our patents in order to enforce such patents against third parties, and such cooperation may not be provided to us.

64

 
 
 
 
 
 
 
 
 
The coverage claimed in a patent application can be significantly reduced before the patent is issued, and its scope can be reinterpreted after issuance. The
issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability. Even if patent applications we license or own currently or in the
future issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors or other third parties from
circumventing  our  patents  by  developing  similar  or  alternative  technologies  or  products  in  a  non-infringing  manner,  or  otherwise  provide  us  with  any
competitive advantage. Challenges from competitors or other third parties could reduce the scope of our patents or render them invalid or unenforceable,
which could limit our ability to stop others from using or commercializing similar or identical technology and product candidates, or limit the duration of the
patent protection for Lumoxiti and our product candidates. The legal proceedings that we may then have to enter into in order to enforce and defend our
intellectual property could be very costly and could distract our management and other personnel from their normal responsibilities, notably in the case of
lawsuits in the United States. The probability of disputes arising over our intellectual property will increase progressively as patents are granted and as the
value  and  appeal  of  the  inventions  protected  by  these  patents  are  confirmed.  The  occurrence  of  any  of  these  events  concerning  any  of  our  patents  or
intellectual property rights could have a material adverse effect our business, prospects, financial condition and results of operations. These risks are even
higher for us, because of our limited financial and human resources.

The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions, and has been
the subject of much litigation in recent years. As a result, the issuance, scope, validity, enforceability, and commercial value of our patent rights are highly
uncertain. Our pending and future patent applications may not result in patents being issued which protect our technology or product candidates or which
effectively prevent others from commercializing competitive technologies and product candidates. Furthermore, our owned and in-licensed patents may be
subject to a reservation of rights by one or more third parties. For example, the research resulting in certain of our owned and licensed patent rights and
technology was funded in part by the U.S. government. As a result, the government may have certain rights, or march-in rights, to such patent rights and
technology.  When  new  technologies  are  developed  with  government  funding,  the  government  generally  obtains  certain  rights  in  any  resulting  patents,
including a non-exclusive license authorizing the government to use the invention for non-commercial purposes. These rights may permit the government to
disclose  our  confidential  information  to  third  parties  and  to  exercise  march-in  rights  to  use  or  allow  third  parties  to  use  our  licensed  technology.  The
government can exercise its march-in rights if it determines that action is necessary because we fail to achieve practical application of the government-funded
technology, because action is necessary to alleviate health or safety needs, to meet requirements of federal regulations, or to give preference to U.S. industry.
In addition, our rights in such inventions may be subject to certain requirements to manufacture products embodying such inventions in the United States.
Any exercise by the government of such rights could harm our competitive position, business, financial condition, results of operations, and prospects.

65

 
 
 
 
 
Third parties may allege that we or our partners infringe, misappropriate or otherwise violate such third parties’ intellectual property rights, which could
prevent or delay our development efforts, stop us from commercializing Lumoxiti or our product candidates, or increase the costs of commercializing
Lumoxiti or our product candidates.

Our commercial success depends on our ability and the ability of our partners to develop, manufacture, market and sell Lumoxiti and our product candidates,
and  use  our  proprietary  technologies,  without  infringing,  misappropriating  or  otherwise  violating  any  intellectual  property  or  proprietary  rights  of  third
parties.  The  field  of  biopharmaceuticals  involves  significant  patent  and  other  intellectual  property  litigation,  which  can  be  highly  uncertain  and  involve
complex legal and factual questions. The interpretation and breadth of claims allowed in some patents covering biopharmaceutical compositions also may be
uncertain and difficult to determine.

We  may  not  be  aware  of  all  third-party  intellectual  property  rights  potentially  relating  to  our  product  candidates.  In  general,  in  the  United  States  patent
applications  are  not  published  until  18  months  after  filing  or,  in  some  cases,  not  at  all.  Therefore,  we  cannot  be  sure  that  we  were  the  first  to  make  the
inventions claimed in any owned or licensed patents or pending patent applications, or that we were the first to file for patent protection for such inventions.
If we were not the first to invent such inventions or first to file any patent or patent application for such inventions, we may be unable to make use of such
inventions in connection with our products. We may need to obtain licenses from third parties (which may not be available under commercially reasonable
terms, or at all), delay the launch of product candidates, or cease the production and sale of certain product candidates or develop alternative technologies
that are the subject of such patents or patent applications, any of which could have a material adverse effect on our business, prospects, financial condition
and results of operations. For example, third parties may claim that lacutamab and other product candidates may use technology protected by their patents.
Although we believe that our current activities and our planned development of lacutamab does not and will not infringe on such patents, which expire in the
near term, third parties may disagree.

Third  parties  may  allege  that  we  or  our  partners  infringe,  misappropriate  or  otherwise  violate  any  such  third-party’s  patents  or  other  intellectual  property
rights and assert infringement claims against us, regardless of their merit. A court of competent jurisdiction could hold that these third-party patents are valid,
enforceable and infringed, which could materially and adversely affect our ability to commercialize Lumoxiti and any product candidates we may develop
and any other product candidates or technologies covered by the asserted third-party patents. In order to successfully challenge the validity of any such U.S.
patent  in  federal  court,  we  would  need  to  overcome  a  presumption  of  validity.  As  this  burden  is  a  high  one  requiring  us  to  present  clear  and  convincing
evidence as to the invalidity of any such U.S. patent claim, there is no assurance that a court of competent jurisdiction would invalidate the claims of any
such U.S. patent. If we are found to infringe a third-party’s intellectual property rights, and we are unsuccessful in demonstrating that such rights are invalid
or unenforceable, we could be required to:

·

bear the potentially significant costs of proceedings brought against us;

66

 
 
 
 
 
 
 
 
·

·

·

pay damages, which may include treble damages and attorney’s fees if we are found to have willfully infringed a third-party’s patent rights;

cease developing, manufacturing and commercializing the infringing technology or product candidates; and

acquire a license to such third-party intellectual property rights, which may not be available on commercially reasonable terms, or at all, and may be
non-exclusive thereby giving our competitors and other third parties access to the same technologies licensed to us.

Even  if  resolved  in  our  favor,  litigation  or  other  intellectual  property  proceedings  may  cause  us  to  incur  significant  expenses  and  could  distract  our
management and other personnel from their normal responsibilities. In addition, there could be public announcements of the results of hearings, motions or
other interim proceedings or developments and if securities analysts or investors perceive these results to be negative, it could have a material adverse effect
on the price of our ordinary shares or ADSs. We may not have sufficient financial or other resources to adequately conduct such litigation or proceedings.
Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial
resources and more mature and developed intellectual property portfolios. Should one or more of the foregoing risks materialize, this could have a material
adverse effect on our reputation, business, prospects, financial condition and results of operations.

Our patents could be found invalid or unenforceable if challenged and we may not be able to protect our intellectual property.

Our and our licensors’ patents and patent applications, if issued, may be challenged, invalidated or circumvented by third parties. U.S. patents and patent
applications may also be subject to interference proceedings, re-examination proceedings, derivation proceedings, post-grant review or inter partes review in
the United States Patent and Trademark Office, or USPTO, challenging our or our licensors’ patent rights. Foreign patents may be subject also to opposition
or  comparable  proceedings  in  the  corresponding  foreign  patent  office.  For  example,  two  of  our  European  patents  with  claims  directed  to  a  class  of  anti-
NKG2A  antibodies  defined  by  characteristics  shared  with  monalizumab  have  been  challenged  in  oppositions  at  the  European  Patent  Office,  or  the  EPO.
Although the Opposition Division of the EPO issued a decision that some claims directed to such class of anti-NKG2A antibodies are valid, the Opposition
Division’s decisions for both patents are currently under appeal. We have also received notices that third parties filed oppositions challenging our in-licensed
European patents directed to certain of our CD39 technology, and these oppositions are currently pending.

In  addition,  we  may  allege  that  third  parties  infringe  our  or  our  licensors’  patents  and  the  defendant  could  counterclaim  that  such  patents  are  invalid  or
unenforceable.  In  patent  litigation  in  the  United  States,  defendant  counterclaims  alleging  invalidity  or  unenforceability  are  commonplace.  Grounds  for  a
validity  challenge  could  be  an  alleged  failure  to  meet  any  of  several  statutory  requirements,  including  lack  of  novelty,  obviousness,  or  non-enablement.
Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information from
the USPTO, or made a misleading statement, during prosecution. The outcome following legal assertions of invalidity and unenforceability is unpredictable.
With respect to the validity question, for example, we cannot be certain that there is no invalidating prior art, of which we or our licensing partners and the
patent examiner were unaware during prosecution.

67

 
 
 
 
 
 
 
 
 
 
Any such patent litigation or proceeding could result in the loss of our or our licensors’ patents, denial of our or our licensors’ patent applications or loss or
reduction in the scope of one or more of the claims of such patents or patent applications. Accordingly, our or our licensors’ rights under any issued patents
may not provide us with sufficient protection against competitive product candidates or processes, we could become unable to manufacture or commercialize
Lumoxiti  or  our  product  candidates  without  infringing  third-party  patent  rights,  and  the  duration  of  the  patent  protection  of  Lumoxiti  or  our  product
candidates could be limited. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is
a risk that some of our confidential information could be compromised by disclosure during this type of litigation. Even if we are successful, such litigation
or proceedings may be costly and may distract our management and other personnel from their normal responsibilities. Any of the foregoing could have a
material adverse effect on our business, prospects, financial condition and results of operations.

Obtaining  and  maintaining  our  patent  protection  depends  on  compliance  with  various  procedural,  document  submission,  fee  payment  and  other
requirements  imposed  by  government  patent  agencies,  and  our  patent  protection  could  be  reduced  or  eliminated  for  non-compliance  with  these
requirements.

Periodic maintenance fees, renewal fees, annuity fees and various other government fees on patents and/or applications will be due to be paid to the USPTO,
and various government patent agencies outside of the United States over the lifetime of our owned and licensed patents and/or patent applications and any
patent rights we may own in the future. In certain circumstances, we may rely on our licensing partners to pay these fees. The USPTO and various foreign
patent agencies require compliance with several procedural, documentary, fee payment and other similar provisions during the patent application process. In
many  cases,  an  inadvertent  lapse  can  be  cured  by  payment  of  a  late  fee  or  by  other  means  in  accordance  with  the  applicable  rules.  There  are  situations,
however, in which non-compliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights
in the relevant jurisdiction. In such an event, potential competitors might be able to enter the market with similar or identical products or technology, which
could have a material adverse effect on our business, prospects, financial condition and results of operations.

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

Changes  in  either  the  patent  laws  or  interpretation  of  the  patent  laws  could  increase  the  uncertainties  and  costs  surrounding  the  prosecution  of  patent
applications and the enforcement or defense of issued patents. For example, from time to time, 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 September 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 such as allowing third-party submission of prior art to the USPTO during patent prosecution. These
changes may favor larger and more established companies that have greater resources to devote to patent application filing and prosecution. Under a first-to-
file system, assuming that other requirements for patentability are met, the first inventor to file a patent application generally will be entitled to the patent on
an invention regardless of whether another inventor made the invention earlier. 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 in March 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.

68

 
 
 
 
 
 
 
 
In  addition,  changes  to  or  different  interpretations  of  patent  laws  in  the  United  States  and  other  countries  may  permit  others  to  use  our  or  our  partners’
discoveries or to develop and commercialize our technology and product candidates without providing any compensation to us, or may limit the number of
patents or claims we can obtain. The patent positions of companies in the biotechnology and pharmaceutical market are particularly uncertain. Recent U.S.
Supreme Court rulings have narrowed the scope of U.S. patent protection available in certain circumstances and weakened the rights of patent owners in
certain situations. This combination of events has created uncertainty with respect to the validity and enforceability of patents, once obtained. Depending on
future  actions  by  the  U.S.  Congress,  the  federal  courts,  and  the  USPTO,  as  well  as  similar  bodies  in  other  countries,  the  laws  and  regulations  governing
patents could change in unpredictable ways that could have a material adverse effect on our existing patent portfolio and our ability to protect and enforce
our intellectual property in the future, which could have a material adverse effect on our business, prospects, financial condition and results of operations.

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

Depending  upon  the  timing,  duration  and  conditions  of  FDA  marketing  authorization  of  Lumoxiti  and  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, or 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. A patent
term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval, only one patent may be extended
and only those claims covering the approved product, a method for using it or a method for manufacturing it may be extended. However, we may not receive
an  extension  if  we  fail  to  apply  within  applicable  deadlines,  fail  to  apply  prior  to  expiration  of  relevant  patents,  fail  to  exercise  due  diligence  during  the
testing phase or regulatory review process 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  Lumoxiti  or  an  applicable  product  could  be  reduced,  possibly  materially,  which  could  have  a  material  adverse  effect  on  our  business,  prospects,
financial condition and results of operations.

69

 
 
 
 
 
 
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 in all jurisdictions where we seek intellectual property protection.

Filing, maintaining, prosecuting and defending patents on Lumoxiti and 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. Consequently, we may not be able to prevent third parties from using our product candidates or technologies in all countries outside the United States,
or from selling or importing products made using our product candidates or technologies in and into the United States or other jurisdictions. 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, and 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  or  other  violation  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 other countries may affect our ability to
obtain adequate protection for our technology and the enforcement of our 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. Should any
of these risks materialize, this could have a material adverse effect on our business, prospects, financial condition and results of operations.

70

 
 
 
 
 
 
 
Third parties may assert ownership or commercial rights to products, product candidates or technologies that we develop.

Third parties have made, and may in the future make, claims challenging the inventorship or ownership of our intellectual property, which may result in the
imposition of additional obligations on us, such as development, royalty and milestone payments. We have written agreements with partners or other third
parties that provide for the ownership of intellectual property arising from our collaborations and our other work with such third parties. These agreements
provide  that  we  must  negotiate  certain  commercial  rights  with  partners  and  other  third  parties  with  respect  to  joint  inventions  or  inventions  made  by  our
partners  or  such  third  parties  that  arise  from  the  results  of  the  collaboration  or  other  work  with  such  third  parties.  In  some  instances,  there  may  not  be
adequate written provisions to address clearly the resolution of intellectual property rights that may arise under our agreements. For example, Orega Biotech
SAS, or Orega Biotech, has made claims of joint ownership of certain patents relating to IPH5201, and we and Orega Biotech have agreed to resolve those
claims in an arbitration proceeding. If we cannot successfully negotiate sufficient ownership and commercial rights to the inventions that result from our use
of a third-party’s materials where required, or if disputes otherwise arise with respect to the intellectual property developed with the use of a third-party’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. We also may be unsuccessful in executing assignment agreements with
each party who, in fact, conceives or develops intellectual property that we regard as our own, or such agreements might not be self-executing or might be
breached.

Litigation may be necessary to resolve an ownership dispute, and if we are not successful, we may be precluded from using certain intellectual property, may
lose our exclusive rights in such intellectual property or may be required to acquire a license to such intellectual property, which may not be available on
commercially reasonable terms or at all. Any of the foregoing could have a material 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, and we may not be successful in obtaining necessary intellectual property rights.

71

 
 
 
 
 
 
 
We license intellectual property from third parties that is critical to our business through license agreements, including but not limited to licenses related to
the manufacture, composition, use and sale of our product candidates, and in the future we may enter into additional agreements that provide us with licenses
to valuable intellectual property or technology. For example, we depend on our license agreement with AstraZeneca for the commercialization of Lumoxiti
and  our  license  agreement  with  Novo  Nordisk  A/S  for  the  development  and  commercialization  of  monalizumab.  Our  license  agreements  impose  various
obligations on us, which may include development, royalty and milestone payments. If we fail to comply with any of these obligations, our licensors may
have  the  right  to  terminate  the  agreements.  If  our  license  agreements  with  AstraZeneca  or  Novo  Nordisk  A/S  or  any  other  current  or  future  licensors
terminate,  we  would  lose  valuable  rights  and  may  be  required  to  cease  our  development,  manufacture  or  commercialization  of  Lumoxiti  or  our  product
candidates, including monalizumab. In addition, our business would suffer if our licensors fail to abide by the terms of the agreements, if our licensors fail to
prevent infringement by third parties, or if the licensed patents or other rights are found to be invalid or unenforceable. Should any of these risks materialize,
this could have a material adverse effect on our business, prospects, financial condition and results of operations.

In addition, disputes may arise regarding intellectual property subject to a license agreement, including:

·

·

·

·

·

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

the extent to which our technology and processes infringe on intellectual property of the counterparty that is not subject to the license agreement;

our diligence obligations under the license agreement and what activities satisfy those diligence obligations;

the inventorship or ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our counterparties and
us; and

the priority of invention of patented technology.

The agreements under which we currently license intellectual property from third parties are complex, and certain provisions in such agreements may be
susceptible to multiple interpretations. The resolution of any contract dispute that may arise could narrow what we believe to be the scope of our rights to the
relevant intellectual property, or modify in a manner adverse to us what we believe to be our or our counterpart’s financial or other obligations under the
relevant agreement, any of which could have material adverse effect on our business, financial condition, results of operations and prospects. If disputes over
intellectual property that we have licensed prevent or impair our ability to maintain our current license agreement on acceptable terms, we may be unable to
unsuccessfully develop and commercialize the affected product candidates.

Additionally, the growth of our business may depend, in part, on our ability to acquire, in-license or use proprietary rights held by third parties. We may be
unable to acquire or in-license intellectual property rights from third parties that we identify as necessary for our product candidates on reasonable terms or at
all. The licensing or acquisition of third-party intellectual property rights is a competitive area, and several more established companies may pursue strategies
to license or acquire third-party intellectual property rights that we may consider attractive. These established companies may have a competitive advantage
over us due to their size, capital resources, and greater clinical development and commercialization capabilities. In addition, companies that perceive us to be
a competitor may be unwilling to assign or license rights to us. We also may be unable to license or acquire third-party intellectual property rights on terms
that would allow us to make an appropriate return on our investment.

72

 
 
 
 
 
 
 
 
 
 
 
 
As part of our business, we collaborate with non-profit and academic institutions to accelerate our preclinical research or development under agreements with
these institutions. Typically, these institutions provide us with an option to negotiate a license to any of the institution’s or its employees’ rights in technology
resulting from the collaboration. Regardless of such option, we may be unable to negotiate a license within the specified timeframe or under terms that are
acceptable to us. If we are unable to do so, the institution may offer the intellectual property rights to other parties, potentially blocking our ability to pursue
our applicable development or commercialization program. If we are unable to successfully obtain rights to required third-party intellectual property rights or
maintain the existing intellectual property rights we have, we may have to abandon the development and commercialization of the relevant program and our
business, financial conditions, results of operations and prospects could be adversely affected.

Third  parties  may  assert  that  our  employees,  consultants  or  independent  contractors  have  wrongfully  used  or  disclosed  confidential  information  or
misappropriated trade secrets of their current or former employers.

We employ individuals who are currently, or 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,  consultants  and  independent  contractors  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
any such individual’s current or 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 our management and other employees. Should any of these
risks materialize, this could have a material adverse effect on our business, prospects, financial condition and results of operations.

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

In  addition  to  patent  protection,  because  we  operate  in  the  highly  technical  field  of  biopharmaceutical  drug  development,  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 seek to protect our trade secrets, in
part, by entering into confidentiality agreements with our employees, consultants, CROs, 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
such party or made known to such party by us during the course of such party’s relationship with us. However, we cannot guarantee that we have entered into
such agreements with each party that may have or have had access to our trade secrets and confidential information and these agreements may be breached,
and we may not have adequate remedies for any breach.

73

 
 
 
 
 
 
 
 
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.  Moreover,  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 to or misappropriated by a third-party, or if any such information was independently developed by a third-party, our competitive position
could be materially harmed.

Our trade and technical secrets include:

·

·

·

·

certain unpatented technical expertise that we believe provides us with an advantage in conducting research and development work in our field;

certain scientific knowledge generated by the work we carry out;

certain information relating to the product candidates we are currently developing; and

certain information relating to the agreements signed between us and third parties.

The unauthorized disclosure or misappropriation of certain of these secrets could allow third parties to offer products or services to compete with ours or
generally have a material adverse effect on our business.

The structures put in place to protect our trade and technical secrets do not constitute a guarantee that one or more of our trade and technical secrets will not
be disclosed or misappropriated. The agreements or other arrangements to protect our trade secrets may fail to provide the protection sought, or are breached,
or that our trade secrets are disclosed to, or developed independently by, our competitors. Should any of these risks materialize, this could have a material
adverse effect on our business, prospects, financial condition and results of operations.

Unauthorized use of our trademarks may generate confusion and result in costs and delays to the detriment of our marketing efforts.

Our  trademarks  are  a  key  component  of  our  identity  and  our  products.  Although  the  key  components  of  our  trademarks  have  been  registered,  notably  in
France and the United States, other companies in the pharmaceutical sector might use or attempt to use similar trademarks or components of our trademarks,
and  thereby  create  confusion  in  the  minds  of  third  parties.  Our  registered  trademarks  may  be  challenged,  infringed,  circumvented  or  declared  generic  or
determined to be infringing on other marks. In addition, there could be potential trademark infringement claims brought by owners of other trademarks that
incorporate variations of our registered or unregistered trademarks.

74

 
 
 
 
 
 
 
 
 
 
 
 
 
In the event we develop trademarks for products that conflict with intellectual property rights of third parties, we would then have to redesign or rename our
products in order to avoid encroaching on the intellectual property rights of third parties. This could prove to be impossible or costly in terms of time and
financial resources and could be detrimental to our marketing efforts. Should any of these risks materialize, this could have a material adverse effect on our
business, prospects, financial condition and results of operations.

Intellectual property rights do not necessarily address all potential threats.

The  degree  of  future  protection  afforded  by  our  intellectual  property  rights  is  uncertain  because  intellectual  property  rights  have  limitations  and  may  not
adequately protect our business or permit us to maintain our competitive advantage. For example:

·

·

·

·

·

·

·

·

·

·

others may be able to make products that are the same as or similar to Lumoxiti and our product candidates or utilize similar technology but that are
not covered by the claims of the patents that we license or may own in the future;

we, or our license partners or current or future collaborators, might not have been the first to make the inventions covered by the issued patent or
pending patent application that we license or may own in the future;

we, or our license partners or current or future collaborators, might not have been the first to file patent applications covering certain of our or their
inventions;

others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our owned or licensed
intellectual property rights;

it is possible that our owned or licensed pending patent applications will not lead to issued patents;

issued patents that we hold rights to may be held invalid or unenforceable, including as a result of legal challenges by our competitors;

our  competitors  might  conduct  research  and  development  activities  in  countries  where  we  do  not  have  patent  rights  and  then  use  the  information
learned from such activities to develop competitive products for sale in our major commercial markets;

we may not develop additional proprietary technologies that are patentable;

the patents of others may harm our business; and

we may choose not to file a patent in order to maintain certain trade secrets or know-how, and a third-party may subsequently file a patent covering
such intellectual property.

75

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Should any of these events occur, they could have a material adverse effect on our business, financial condition, results of operations, and prospects.

Risks Related to Ownership of Our Ordinary Shares and the ADSs

The trading price of our equity securities may be volatile, and purchasers of our ordinary shares or ADSs could incur substantial losses.

It is likely that the price of our ordinary shares and ADSs will be significantly affected by events such as announcements regarding scientific and clinical
results  concerning  product  candidates  currently  being  developed  by  us,  our  collaboration  partners  or  our  main  competitors,  changes  in  market  conditions
related to our sector of activity, announcements of new contracts, technological innovations and collaborations by us or our main competitors, developments
concerning  intellectual  property  rights,  as  well  as  the  development,  regulatory  approval  and  commercialization  of  new  products  by  us  or  our  main
competitors and changes in our financial results.

Equity  markets  are  subject  to  considerable  price  fluctuations,  and  often,  these  movements  do  not  reflect  the  operational  and  financial  performance  of  the
listed  companies  concerned.  In  particular,  biotechnology  companies’  share  prices  have  been  highly  volatile  and  may  continue  to  be  highly  volatile  in  the
future. As we operate in a single industry, we are especially vulnerable to these factors to the extent that they affect our industry. Fluctuations in the stock
market as well as the macro-economic environment could significantly affect the price of our ordinary shares. As a result of this volatility, investors may not
be able to sell their ordinary shares or ADSs at or above the price originally paid for the security. The market price for our ordinary shares and ADSs may be
influenced by many factors, 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;

adverse results of delays in our or any of our competitors’ preclinical studies or clinical trials;

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;

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;

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

76

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
·

·

·

·

·

·

·

price and volume fluctuations in trading of our ordinary shares on Euronext Paris;

additions or departures of key management or scientific personnel;

disputes or other developments related to proprietary rights, including patents, litigation matters and our ability to obtain patent and other intellectual
property 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;

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 investors 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.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, the price of the ordinary
shares or 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. As a public company in France since 2006, our equity securities are currently subject to coverage by a number of analysts. If fewer securities or
industry analysts cover our company, the trading price for the 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.

We  do  not  currently  intend  to  pay  dividends  on  our  securities  and,  consequently,  your  ability  to  achieve  a  return  on  your  investment  will  depend  on
appreciation in the price of the ordinary shares and ADSs. In addition, French law (including any temporary measures taken in response to COVID-19
pandemic) may limit the amount of dividends we are able to distribute.

We have never declared or paid any cash dividends on our ordinary shares 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, the holders of our ordinary shares and ADSs are not likely to receive any dividends for
the  foreseeable  future  and  the  success  of  an  investment  in  our  ordinary  shares  and  ADSs  depends  upon  any  future  appreciation  in  value.  Consequently,
investors may need to sell all or part of their holdings of the ordinary shares or ADSs after price appreciation, which may never occur, as the only way to
realize any future gains on their investment. There is no guarantee that the ordinary shares or ADSs will appreciate in value or even maintain the price at
which our shareholders have purchased them.

77

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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. Moreover, pursuant to French law, we must allocate 5% of
our unconsolidated net profit for each year to our legal reserve fund before dividends, should we propose to declare any, may be paid for that year, until the
amount in the legal reserve is equal to 10% of the aggregate nominal value of our issued and outstanding share capital. In addition, payment of dividends
may subject us to additional taxes under French law. Therefore, we may be more restricted in our ability to declare dividends than companies that are not
incorporated  in  France.  See  “Description  of  Share  Capital—Key  Provisions  of  Our  Bylaws  and  French  Law  Affecting  Our  Ordinary  Shares”  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.

In addition, exchange rate fluctuations may affect the amount of euro 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 euro, if any. These factors could harm the value of the ADSs, and, in
turn, the U.S. dollar proceeds that holders receive from the sale of the 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.

Future sales of a substantial number of our ADSs or ordinary shares, or the perception that such sales will occur, could cause a decline in the market price of
our ADSs and/or ordinary shares. Sales in the United States of our ADSs and ordinary shares held by our directors, officers and affiliated shareholders or
ADS holders are subject to restrictions. If these shareholders or ADS holders sell substantial amounts of ordinary shares or ADSs in the public market, or the
market  perceives  that  such  sales  may  occur,  the  market  price  of  our  ADSs  or  ordinary  shares  and  our  ability  to  raise  capital  through  an  issue  of  equity
securities in the future could be adversely affected.

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

Our ADSs are listed on Nasdaq, and our ordinary shares are admitted to trading on Euronext Paris. Trading of the ADSs or ordinary shares in these markets
take place in different currencies (U.S. dollars on Nasdaq and euro on Euronext Paris), and at different times (resulting from different time zones, different
trading days and different public holidays in the United States and France). The trading prices of our ordinary shares on these two markets may differ due to
these  and  other  factors.  Any  decrease  in  the  price  of  our  ordinary  shares  on  Euronext  Paris  could  cause  a  decrease  in  the  trading  price  of  the  ADSs  on
Nasdaq. Investors could seek to sell or buy our ordinary shares to take advantage of any price differences between the markets through a practice referred to
as arbitrage. Any arbitrage activity could create unexpected volatility in both our share prices on one exchange, and the ordinary shares available for trading
on  the  other  exchange.  In  addition,  holders  of  ADSs  are  not  immediately  able  to  surrender  their  ADSs  and  withdraw  the  underlying  ordinary  shares  for
trading on the other market without effecting necessary procedures with the depositary. This could result in time delays and additional cost for holders of
ADSs. We cannot predict the effect of this dual listing on the value of our ordinary shares and the ADSs. However, the dual listing of our ordinary shares and
the ADSs may reduce the liquidity of these securities in one or both markets and may adversely affect the development of an active trading market for the
ADSs in the United States.

78

 
 
 
 
 
 
 
 
 
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 Executive Board and of our Supervisory Board 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
Executive Board 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  have  interests  that  are  different  from,  or  in  addition  to,  your  interests  as  a
shareholder or holder of ADSs. See “Item 16G.—Corporate Governance.”

U.S. investors may have difficulty enforcing civil liabilities against our company and members of the Executive Board and the Supervisory Board.

Most  of  the  members  of  our  Executive  Board  and  Supervisory  Board  and  the  experts  named  therein  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 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.

79

 
 
 
 
 
 
 
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  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 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;

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 EU are subject to prior authorization of the Ministry of Economy;

a merger (i.e., in a French law context, a share for share exchange following which our company would be dissolved 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 Executive Board, 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 100% of our shareholders to approve it;

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

our shareholders may in the future grant our Executive Board broad authorizations to increase our share capital or to issue additional ordinary shares
or  other  securities  (for  example,  warrants)  to  our  shareholders,  the  public  or  qualified  investors,  including  as  a  possible  defense  following  the
launching of a tender offer for our ordinary shares;

our shareholders have preferential subscription rights on a pro rata basis on the 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 meeting (by a two-thirds majority vote) of our shareholders or on an individual
basis by each shareholder;

our Supervisory Board appoints the members of the Executive Board and shall fill any vacancy within two months;

our Supervisory Board has the right to appoint members of the Supervisory Board to fill a vacancy created by the resignation or death of a member of
the  Supervisory  Board  for  the  remaining  duration  of  such  member’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 Supervisory Board;

our Executive Board can be convened by the chairman of the Executive Board or other members of the Executive Board delegated for this purpose;

our Supervisory Board can be convened by the chairman or the vice-chairman of the Supervisory Board. A member of the Executive Board or one-
third of the members of the Supervisory Board may send a written request to the chairman to convene the Supervisory Board. If the chairman does not
convene  the  Supervisory  Board  15  days  following  the  receipt  of  such  request,  the  authors  of  the  request  may  themselves  convene  the  Supervisory
Board;

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

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  members  of  the  Executive  Board  and/or  members  of  the  Supervisory  Board  with  or  without
cause;

the crossing of certain ownership thresholds has to be disclosed and can impose certain obligations;

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

transfers of shares shall comply with applicable insider trading rules and regulations, and in particular with the Market Abuse Regulation 596/2014 of
April 16, 2014; and

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

Purchasers of ADSs in the U.S. offering are not directly holding our ordinary shares.

81

 
 
 
 
 
 
 
 
 
 
 
 
 
 
A  holder  of  ADSs  is  not  treated  as  one  of  our  shareholders  and  does  not  have  direct  shareholder  rights.  French  law  governs  our  shareholder  rights.  The
depositary, through the custodian or the custodian’s nominee, is the holder of the ordinary shares underlying ADSs held by purchasers of ADSs in the U.S.
offering. Purchasers of ADSs in the U.S. offering have ADS holder rights. The deposit agreement among us, the depositary and purchasers of ADSs in the
U.S. offering, as an ADS holder, and all other persons directly and indirectly holding ADSs, sets out ADS holder rights, as well as the rights and obligations
of us and the depositary.

Your  right  as  a  holder  of  ADSs  to  participate  in  any  future  preferential  subscription  rights  offering  or  to  elect  to  receive  dividends  in  shares  may  be
limited, which may cause dilution to your holdings.

According to 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 deposit agreement provides that the
depositary will not make rights available to you 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 deposit agreement the depositary may require satisfactory assurances from us that extending the offer to holders of ADSs
does not require registration of any securities under the Securities Act before making the option available to holders of 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 you will
receive no value for these rights.

You may not be able to exercise your right to vote the ordinary shares underlying your ADSs.

Holders  of  ADSs  may  exercise  voting  rights  with  respect  to  the  ordinary  shares  represented  by  the  ADSs  only  in  accordance  with  the  provisions  of  the
deposit agreement. The 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 (i) the notice of the meeting or solicitation of consent or proxy
sent by us and (ii) a statement as to the manner in which instructions may be given by the holders.

82

 
 
 
 
 
 
 
 
You may instruct the depositary of your ADSs to vote the ordinary shares underlying your ADSs. Otherwise, you will not be able to exercise your right to
vote,  unless  you  withdraw  the  ordinary  shares  underlying  the  ADSs  you  hold.  However,  you  may  not  know  about  the  meeting  far  enough  in  advance  to
withdraw those ordinary shares. If we ask for your instructions, the depositary, upon timely notice from us, will notify you of the upcoming vote and arrange
to  deliver  our  voting  materials  to  you.  We  cannot  guarantee  you  that  you  will  receive  the  voting  materials  in  time  to  ensure  that  you  can  instruct  the
depositary to vote your ordinary shares or to withdraw your ordinary shares so that you can vote them yourself. If the depositary does not receive timely
voting instructions from you, it may give a proxy to a person designated by us to vote the ordinary shares underlying your ADSs. 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 you may
not be able to exercise your right to vote, and there may be nothing you can do if the ordinary shares underlying your ADSs are not voted as you requested.

You may be subject to limitations on the transfer of your ADSs and the withdrawal of the underlying ordinary shares.

Your ADSs 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 your 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 deposit agreement, or for any other reason subject to your right to cancel your ADSs and
withdraw the underlying ordinary shares. Temporary delays in the cancellation of your 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,  you  may  not  be  able  to  cancel  your  ADSs  and  withdraw  the
underlying ordinary shares when you owe 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.

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  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 Executive Board and Supervisory Board members
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 file
financial reports on an annual and semi-annual basis, 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 are not required to file quarterly reports on Form 10-Q or current reports on Form 8-K under the Exchange Act. In
addition, foreign private issuers are not required to file their annual report on Form 20-F until four months after the end of each fiscal year. Accordingly,
there is and will be less publicly available information concerning our company than there would be if we were not a foreign private issuer.

83

 
 
 
 
 
 
 
 
As a foreign private issuer, we are permitted to adopt certain home country practices in relation to corporate governance matters that differ significantly
from Nasdaq corporate governance listing standards and these practices may afford less protection to shareholders than they would enjoy if we complied
fully with Nasdaq corporate governance listing standards.

As a foreign private issuer listed on Nasdaq, we are subject to their corporate governance listing standards. However, Nasdaq rules permit foreign private
issuers  to  follow  the  corporate  governance  practices  of  their  home  country.  Some  corporate  governance  practices  in  France  may  differ  significantly  from
Nasdaq  corporate  governance  listing  standards.  For  example,  neither  the  corporate  laws  of  France  nor  our  bylaws  require  a  majority  of  our  Supervisory
Board members to be independent and although the corporate governance code to which we currently refer (the AFEP/MEDEF code) recommends that, in a
widely-held company like ours, a majority of the Supervisory Board members be independent (as construed under such code), this code only applies on a
“comply-or-explain”  basis  and  we  may  in  the  future  either  decide  not  to  apply  this  recommendation  or  change  the  corporate  code  to  which  we
refer. Furthermore, we include non-independent members of the Supervisory Board as members of our compensation and nomination committee, and our
independent Supervisory Board members do not necessarily hold regularly scheduled meetings at which only independent members of the Supervisory Board
are  present.  Currently,  we  intend  to  follow  home  country  practice  to  the  maximum  extent  possible.  Therefore,  our  shareholders  may  be  afforded  less
protection  than  they  otherwise  would  have  under  corporate  governance  listing  standards  applicable  to  U.S.  domestic  issuers.  For  an  overview  of  our
corporate governance practices, see “Item 16G.—Corporate Governance.”

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

We  are  an  “emerging  growth  company,”  as  defined  in  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, 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 will not 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.

84

 
 
 
 
 
 
 
We cannot predict if investors will find the ordinary shares or ADSs less attractive because we may rely on these exemptions. If some investors find the
ordinary shares or ADSs less attractive as a result, there may be a less active trading market for the ordinary shares or ADSs and the price of the ordinary
shares or ADSs may be more volatile. We may take advantage of these exemptions until such time that we are no longer an emerging growth company. We
would cease to be an emerging growth company upon the earliest to occur of (1) the last day of the fiscal year in which we have more than $1.07 billion in
annual revenue; (2) the date we qualify as a “large accelerated filer” with at least $700 million of equity securities held by non-affiliates; (3) the issuance, in
any three year period, by our company of more than $1.0 billion in non-convertible debt securities held by non-affiliates; and (4) the last day of the fiscal
year ending after the fifth anniversary of our initial public offering of the ADSs.

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  an
issuer’s most recently completed second fiscal quarter and, accordingly, our next determination will be made on June 30, 2020. In the future, we would lose
our foreign private issuer status if we to fail to meet the requirements necessary to maintain our foreign private issuer status as of the relevant determination
date. For example, if more than 50% of our securities are held by U.S. residents and more than 50% of the members of our Executive Board or Supervisory
Board are residents or citizens of the United States, we could lose our foreign private issuer status.

The regulatory and compliance costs to us under U.S. securities laws as a U.S. domestic issuer may be significantly more than costs we incur as a foreign
private issuer. If we are not a foreign private issuer, we will 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. generally accepted accounting principles, or U.S. GAAP, rather than IFRS, and modify
certain of our policies to comply with corporate governance practices required of U.S. domestic issuers. Such conversion of our financial statements to U.S.
GAAP would involve significant time and cost. In addition, we may 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 above and exemptions from procedural requirements related
to the solicitation of proxies.

If we are a passive foreign investment company, there could be adverse U.S. federal income tax consequences to U.S. holders.

Based on our analysis of our income, assets, activities and market capitalization for our taxable year ended December 31, 2018, we believe that we were not a
passive foreign investment company, or PFIC, for the taxable year ended December 31, 2019. However, there can be no assurance that we will not be a PFIC
in the current year or for any future taxable year. Under the Code, a non-U.S. company will be a PFIC for any taxable year in which (1) 75% or more of its
gross income consists of passive income or (2) 50% or more of the average quarterly value of its assets consists of assets that produce, or are held for the
production  of,  passive  income.  For  purposes  of  these  tests,  passive  income  includes  dividends,  interest,  gains  from  the  sale  or  exchange  of  investment
property and certain rents and royalties. In addition, for purposes of the above calculations, a non-U.S. corporation that directly or indirectly owns at least
25% by value of the shares of another corporation is treated as if it held its proportionate share of the assets and received directly its proportionate share of
the income of such other corporation. If we are a PFIC for any taxable year during which a U.S. holder (as defined below under “Item 10E.—Taxation –
Material  U.S.  Federal  Income  Tax”)  holds  our  ordinary  shares  or  ADSs,  we  will  continue  to  be  treated  as  a  PFIC  with  respect  to  such  U.S.  holder  in  all
succeeding years during which the U.S. holder owns the ordinary shares or ADSs, regardless of whether we continue to meet the PFIC test described above,
unless the U.S. holder makes a specified election once we cease to be a PFIC. If we are a PFIC for any taxable year during which a U.S. holder holds our
ordinary shares or ADSs, the U.S. holder may be subject to adverse tax consequences regardless of whether we continue to qualify as a PFIC, including
ineligibility for any preferred tax rates on capital gains or on actual or deemed dividends, interest charges on certain taxes treated as deferred, and additional
reporting requirements. For further discussion of the PFIC rules and the adverse U.S. income tax consequences in the event we are classified as a PFIC, see
the section of this Annual Report titled “Item 10E.—Taxation– Material U.S. Federal Income Tax Considerations.”

85

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

If a U.S. holder is treated as owning, directly, indirectly or constructively, at least 10% of the value or voting power of our ordinary shares or ADSs, such
U.S. holder may be treated as a “United States shareholder” with respect to each “controlled foreign corporation” in our group, if any. Our group currently
includes one U.S. subsidiary and, therefore, under current law our current non-U.S. subsidiary and any future newly formed or acquired non-U.S. subsidiaries
will be treated as controlled foreign corporations, regardless of whether we are treated as a controlled foreign corporation. A United States shareholder of a
controlled foreign corporation may 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  controlled  foreign  corporations,  regardless  of  whether  we  make  any  distributions.  An
individual  that  is  a  United  States  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  United  States  shareholder  that  is  a  U.S.  corporation.  Failure  to  comply  with  controlled  foreign  corporation
reporting obligations may subject a United States shareholder to significant monetary penalties. We cannot provide any assurances that we will furnish to any
United States shareholder information that may be necessary to comply with the reporting and tax paying obligations applicable under the controlled foreign
corporation  rules  of  the  Code.  U.S.  holders  should  consult  their  tax  advisors  regarding  the  potential  application  of  these  rules  to  their  investment  in  our
ordinary shares or ADSs.

A.       History and Development of the Company.

Our legal name and commercial name is Innate Pharma S.A. We were incorporated under the laws of France on September 23, 1999 as a société par actions
simplifiée and converted into a société anonyme, or S.A., on June 13, 2005. Our headquarters are located at 117, Avenue de Luminy, 13009 Marseille, France.
In  2008,  we  incorporated  our  wholly-owned  U.S.  subsidiary,  Innate  Pharma  Inc.  In  2019,  we  incorporated  our  wholly-owned  French  subsidiary,  Innate
Pharma France S.A.S (registered under number SIREN 844 853 119).

We  are  registered  at  the  Marseille  Business  and  Company  Registry  (Registre  du  commerce  et  des  sociétés)  under  the  number  SIREN  424  365  336  RCS
Marseille. Our telephone number at our principal executive offices is +33 4 30 30 30 30. Our agent for service of process in the United States is Corporation
Service Company located at 251 Little Falls Drive,

Commission maintains a website (www.sec.gov) that contains reports, proxy and information statements and other information regarding registrants, such as
Innate, that file electronically with the SEC.

B.       Business Overview.

We  are  a  biotechnology  company  focused  on  discovering,  developing  and  commercializing  first-in-class  therapeutic  antibodies  designed  to  harness  the
immune system for the treatment of oncology indications with significant unmet medical need. We have extensive experience in research and development in
immuno-oncology,  having  been  pioneers  in  the  understanding  of  natural  killer  cell,  or  NK  cell,  biology,  and  later  expanding  our  expertise  in  the  tumor
microenvironment, tumor antigens and antibody engineering fields. We have built, internally and through our business development strategy, a broad and
diversified portfolio including an approved product, four clinical product candidates and a robust preclinical pipeline. We have entered into collaborations
with  leaders  in  the  biopharmaceutical  industry,  such  as  AstraZeneca  and  Sanofi,  to  leverage  their  development  capabilities  and  expertise  for  some  of  our
candidates, and we have received upfront and milestone payments and equity investments from our collaborations of an aggregate of approximately $565
million  over  the  last  ten  years.  We  believe  our  product  candidates  and  clinical  development  approach  are  differentiated  from  current  immuno-oncology
therapies and have the potential to significantly improve the clinical outcome for patients with cancer.

The immune system is the body’s natural defense against invading organisms and pathogens and is comprised of two arms: the innate immune system and
adaptive  immune  system.  Recent  immunotherapy  developments  have  focused  on  generating  a  tumor  antigen-specific  T  cell  response  and  have  led  to  an
unprecedented  change  in  the  treatment  paradigm  of  many  solid  tumor  cancers.  Despite  these  successes,  the  breadth  and  durability  of  the  clinical  benefit
achieved has been limited to a subset of patients and tumor types. Our innovative approach to immuno-oncology aims to broaden and amplify anti-tumoral
immune responses by leveraging both the adaptive and the innate immune systems.

87

 
 
 
 
 
 
 
 
 
 
 
 
The innate immune system is comprised of a variety of cells, including NK cells, which are involved in anti-cancer immunosurveillance through a variety of
modalities. Activation of the innate immune system also helps trigger the adaptive immune system to elicit a response directed against specific antigens and
can provide durable immune memory. Our scientific expertise, strategic collaborations and discovery engine are focused on harnessing the potential of the
innate immune system across three pillars.

We are developing a pipeline of innovative immunotherapies that we believe have the potential to provide a significant clinical benefit to cancer patients. The
following table summarizes our commercial, clinical and preclinical pipeline.

“SCCHN” denotes Squamous Cell Carcinoma of the Head and Neck; “CRC” denotes Colorectal Cancer; “MF” denotes Mycosis Fungoides; “PTCL” denotes
Peripheral T-cell Lymphomas; “NSCLC” denotes Non-Small Cell Lung Cancer; and “HCC” denotes Hepatocellular Carcinoma.

In addition to these product candidates, we have an active development pipeline with programs in the discovery and preclinical stages.

·

Broad spectrum immune checkpoint inhibitors. We are targeting checkpoints expressed on NK cells and myeloid cells, rather than focusing solely
on T cells, in order to increase the pool of anti-tumor effector cells and potentially mount a larger anti-tumor response. Our most advanced checkpoint
inhibitor  product  candidate,  monalizumab,  is  a  dual  checkpoint  inhibitor  designed  to  activate  both  tumor-infiltrating  NK  cells  and  CD8+  T  cells,
potentially resulting in increased effector functions and greater killing of tumor cells by the immune system. By activating NK cells, which are potent
producers of cytokines, monalizumab may also favor dendritic cell maturation, which may in turn increase the generation of a T cell response against
the tumor. We believe monalizumab has the potential to be a first-in-class treatment for various cancer indications, which we define as the ability to
target  a  receptor  that  has  not  previously  been  targeted  to  treat  cancer  indications,  given  that  no  approved  products  or,  to  our  knowledge,  product
candidates in clinical development by third parties target the NKG2A receptor.

88

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We and AstraZeneca AB, or AstraZeneca, are currently evaluating monalizumab in an open-label Phase Ib/II clinical trial in combination with cetuximab, an
epidermal growth factor receptor, or EGFR, inhibitor in patients with relapsed or metastatic squamous cell carcinoma of the head and neck, or R/M SCCHN.
In  addition  to  unleashing  tumor-infiltrating  NK  and  CD8+  T  cells,  the  combination  of  cetuximab  and  monalizumab  may  activate  NK  cells  through  the
recognition  of  cetuximab-coated  tumor  cells  via  the  CD16  activating  receptor.  In  2018,  we  presented  data  from  a  first  expansion  cohort  from  this  trial,
including efficacy data and have since then expanded to two additional expansion cohorts. The second expansion cohort is evaluating the combination of
monalizumab and cetuximab in patients previously treated with both chemotherapy and checkpoint inhibitors and the third expansion cohort is evaluating the
combination of monalizumab, cetuximab and an anti-PD-L1 checkpoint inhibitor in IO-naïve patients.

Additional  one-year  survival  data  from  the  first  expansion  cohort  was  presented  at  the  European  Society  for  Medical  Oncology,  or  ESMO,  2019  annual
meeting, and we expect to present preliminary efficacy data from the second expansion cohort in the first half of 2020 and from the third expansion cohort in
the second half of 2020. In September 2019, we announced that AstraZeneca will advance monalizumab into a Phase III randomized clinical trial evaluating
monalizumab in combination with cetuximab in patients suffering from recurrent or metastatic SCCHN, and that we and AstraZeneca will co-fund the trial.

AstraZeneca is also evaluating monalizumab in a Phase I/II clinical trial in combination with durvalumab, an anti-PD-L1 immune checkpoint inhibitor, in
patients with advanced solid tumors, including colorectal cancer, or CRC.

We are also exploring the possibility of developing an antibody designed to reduce the effects of Siglec-9 receptors, expressed on NK cells and myeloid cells,
for the treatment of cancer.

·

·

Tumor  antigen  targeting.  We  are  developing  antibodies  that  target  tumor  antigens  in  the  form  of  (i)  antibody-drug  conjugates,  or  ADCs,  (ii)
antibody-dependent cellular cytotoxicity, or ADCCs, inducing antibodies and (iii) antibody-based multi-specific NK cell engagers, or NKCEs.

ADCs.  One  approach  is  to  directly  kill  tumor  cells  using  either  an  ADC,  such  as  with  our  IPH43  program,  or  an  immunotoxin,  such  as  with  our
commercial-stage  product  Lumoxiti.  Lumoxiti  is  a  marketed,  first-in-class  CD22-directed  immunotoxin,  which  was  approved  by  the  FDA  under
priority  review  in  September  2018  for  the  treatment  of  adult  patients  with  relapsed  or  refractory,  or  R/R,  hairy  cell  leukemia,  or  HCL,  who  have
received  at  least  two  prior  systemic  therapies,  including  treatment  with  a  purine  nucleoside  analog,  or  PNA.  Lumoxiti  is  the  first  FDA-approved
treatment for HCL in over 20 years. IPH43 is as an ADC targeting MICA/B that we are developing for the treatment of oncology indications.

89

 
 
 
 
 
 
 
 
 
·

·

·

ADCCs. Another approach is to develop antibodies that activate cells of the innate immune system, such as NK cells, in order to induce ADCC. Our
most advanced product candidate utilizing this approach is lacutamab (IPH4102), an antibody targeting KIR3DL2, a receptor not expressed on healthy
tissues  except  on  a  subset  of  NK  cells  and  T  cells.  We  believe  that  lacutamab  has  the  potential  to  be  a  first-in-class  treatment  for  various  cancer
indications, given that no approved products or, to our knowledge, product candidates in clinical development by third parties target KIR3DL2. We are
developing  lacutamab  for  the  treatment  of  various  forms  of  T  cell  lymphomas,  or  TCL,  including  cutaneous  T  cell  lymphoma,  or  CTCL,  and
peripheral T cell lymphoma, or PTCL. Mycosis fungoides, or MF, is the most common form of CTCL, and Sézary syndrome is an aggressive form of
CTCL. In January 2019, the FDA granted lacutamab Fast Track designation for the treatment of adults with R/R, Sézary syndrome who have received
at least two prior systemic therapies. Lacutamab has also been granted orphan drug designation in the European Union and in the United States for the
treatment of CTCL. In May 2019, we initiated a Phase II clinical trial evaluating lacutamab in different subtypes of TCL. We expect first preliminary
efficacy data for Sézary and MF cohorts starting in 2021.

Antibody-based multi-specific NKCEs. We are also developing a pipeline of multi-specific NKCEs that engage an activating checkpoint, NKp46, on
NK  cells,  in  order  to  direct  NK  cells  to  the  tumor.  We  believe  this  innovative  approach  may  allow  for  immuno-oncology  treatments  with  a  more
favorable safety profile than T cell engagers.

Suppressive  factors  of  the  TME.  We  are  developing  product  candidates  that  target  suppressive  pathways  of  the  TME  in  order  to  relieve  the
immunosuppression  of  the  innate  and  adaptive  immune  responses.  We  are  developing  avdoralimab,  an  anti-C5aR  antibody  that  disrupts  the
complement pathway. In January 2018, we entered into a non-exclusive clinical trial collaboration with AstraZeneca for avdoralimab. As part of this
collaboration, we are conducting a Phase I/II clinical trial to evaluate the safety and efficacy of avdoralimab in combination with durvalumab as a
treatment  for  patients  with  solid  tumors,  including  NSCLC  and  HCC.  We  reported  preliminary  data  from  this  dose-escalation  clinical  trial  in  the
second  half  of  2019.  In  addition,  we  are  developing  product  candidates  that  disrupt  the  adenosine  pathway,  including  IPH5201,  an  anti-CD39
antibody,  and  IPH5301,  an  anti-CD73  antibody.  In  October  2018,  we  entered  into  a  collaboration  and  option  agreement  for  IPH5201  with
AstraZeneca.  In  March  2020,  the  first  patient  was  dosed  in  the  Phase  I  clinical  trial  evaluating  IPH5201  in  monotherapy  and  in  combination  with
durvalumab (anti-PD-L1) and with or without oleclumab (anti-CD-73 monoclonal antibody). We expect to file an IND for IPH5301 in the first half of
2020.

90

 
 
 
 
 
 
 
 
 
 
 
 
 
Our collaborations allow us to leverage the expertise and resources of large pharmaceutical companies and research institutions with the goal of accelerating
the development of several of our product candidates while providing financing to expand the development of our proprietary product candidates. Over the
last  ten  years  we  have  received  an  aggregate  of  approximately  $565  million  in  upfront  and  milestone  payments  and  equity  investments  from  our
collaborations.  Under  our  existing  collaboration  agreements  and  any  license  agreements  that  become  effective  upon  the  exercise  by  our  collaborators  of
options to license future product candidates, we may be eligible to receive an aggregate of approximately $5.5 billion in future contingent payments, which
includes $100 million we expect to receive upon dosing of the first patient in the first Phase III clinical trial for monalizumab. AstraZeneca is expected to
commence a Phase III clinical trial of monalizumab in combination with cetuximab in 2020. With respect to the programs for which we have an existing
collaboration or similar agreement, future contingent payments are dependent upon our achievement of specified development and sales milestones. With
respect to the programs for which our collaborators have been granted an option, future contingent payments are dependent upon our collaborators exercising
such  options,  which  would  result  in  up-front  option  exercise  fees,  and  upon  our  achievement  of  specified  development  and  sales  milestones  in  those
particular programs. The aggregate $5.5 billion in future contingent payments assumes that our collaborators exercise all of the options we have granted to
them and that we achieve all related development, clinical, regulatory and sales milestones. In April 2015, we entered into a collaboration with AstraZeneca
relating to monalizumab, and in October 2018, AstraZeneca expanded this collaboration to gain full oncology rights for monalizumab and options to acquire
development  rights  to  IPH5201  and  four  of  our  other  preclinical  programs.  Concurrently,  we  acquired  U.S.  and  EU  commercial  rights  to  Lumoxiti,  and
AstraZeneca  acquired  a  9.8%  equity  stake  in  our  company.  We  have  also  entered  into  a  collaboration  agreement  with  Sanofi  Aventis  Recherche  &
Développement, or Sanofi, which includes two programs based on our multi-specific, NKCE technology.

Our Strategy

Our  goal  is  to  harness  the  immune  system  for  the  treatment  of  conditions  with  serious  unmet  medical  needs  in  oncology.  By  leveraging  our  extensive
experience  in  immuno-oncology  research  and  development,  we  strive  to  continue  to  internally  discover,  externally  identify  and  develop  a  broad  and

Activating Innate Immunity: Harnessing the Power of Immunotherapy to Treat Cancer

The Innate Immune System: Gatekeeper of the Adaptive Immune System

The immune system is the body’s defense against invading organisms and pathogens and is comprised of two arms: the innate immune system and adaptive
immune system.

The  innate  immune  system  represents  the  first  barrier  of  immune  defense  because  it  reacts  almost  immediately  against  threats  and  serves  as  a  catalyst  to
mobilize  other  components  of  the  immune  system.  The  innate  immune  system  functions  to  identify,  attack  and  kill  pathogens  or  cancer  cells,  produce
cytokines and activate the complement cascade and the adaptive immune system through antigen presentation. These functions involve a variety of cells,
including NK cells, dendritic cells, monocytes, macrophages and neutrophils. These cells then launch adaptive immune responses while also mounting their
own effector responses. Throughout the body, cells of the innate immune system play a critical role in the immunosurveillance and detection of the formation
of cancer cells.

Once activated, the adaptive immune system responds with large numbers of effector cells directed against specific antigens and can provide durable immune
memory. An adaptive immune response is highly specific to particular antigens expressed by pathogens or cancer cells, but it requires time to develop in a
process known as priming. Key components of the adaptive immune system include antibodies, which are produced by B cells and that bind to antigens and
mark them for destruction by other immune cells, and T cells, which recognize antigens on diseased cells and then attack and eliminate them. The adaptive
immune response is targeted and potent and has the potential to provide a long-lasting immune memory.

92

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The graphic above shows the interaction of the cells in the innate immune system and adaptive immune system in the presence of microbial infections and
tumors. The various cells in the innate immune system rapidly launch their own effector response to fight the infection or tumor while also activating the B
cells and T cells in the adaptive immune system. Once activated, the adaptive immune system launches a slower but more targeted effector response against
the infection or tumor.

Key Elements to Modulating the Activity of Immune Cells to Treat Cancer

Cells implicated in innate and adaptive immunity can have different impacts on the treatment of cancer. While cytotoxic CD8+ T cells and NK cells help
eliminate  tumors,  subsets  of  T  cells,  such  as  regulatory  T  cells,  and  subsets  of  myeloid  cells,  such  as  myeloid-derived  suppressor  cells  (MDSCs),  can  be
harmful to the host by contributing to an immunosuppressive environment and promoting tumor growth.

Immune  cell  activity  is  controlled  by  many  activating  and  inhibitory  factors,  including  activating  receptors  and  inhibitory  receptors,  called  checkpoints,
which are expressed at the surface of these cells. PD-1, LAG-3, TIGIT and NKG2A are examples of inhibitory checkpoints while OX-40, CD137, NKG2D
and  NKp46  are  examples  of  activating  checkpoints.  When  engaged,  the  inhibitory  checkpoints  can  impair  anti-tumor  immunity  of  adaptive  and  innate
immune cells such as CD8+ T cells or NK cells, thereby contributing to tumor escape from immune control. Inhibitory checkpoints are potential therapeutic
targets for restoring anti-cancer immunosurveillance.

93

 
 
 
 
 
 
 
 
The Role of the Innate Immune System as a Modality for Cancer Therapies with Significant Potential

Cancer has historically been treated with surgery, radiation therapy, chemotherapy, targeted therapy, hormone therapy or a combination of these treatments
that  are  directed  at  the  tumor  itself.  More  recently,  advances  in  the  understanding  of  the  immune  system’s  role  in  cancer  have  led  to  immunotherapy
becoming an important therapeutic modality, shifting the therapeutic target from the tumor to the host and focusing on the immune system and the TME in
order to reactivate its immunosurveillance against cancer.

Cancer  immunotherapy  began  with  treatments  that  nonspecifically  activated  the  immune  system,  such  as  IL-2  and  IFNa  cytokines  therapies,  which  had
limited efficacy, significant toxicity or both. More recent immunotherapy developments have instead focused on the generation of a tumor antigen-specific T
cell response, in particular by modulating the activity of inhibitory receptors expressed by T cells. This modulation can limit T cells expansion, such as with
anti-CTLA-4  therapy,  or  limit  their  effector  properties,  such  as  with  anti-PD-1  or  anti-PD-L1  therapies.  The  therapeutic  targeting  of  inhibitory  receptors
controlling T cell function has led to an unprecedented change in the treatment paradigm of many cancers in solid tumors, such as melanoma, non-small cell
lung cancer and renal cell carcinoma, and in hematopoietic malignancies, such as Hodgkin lymphoma. Despite these successes, the breadth and durability of
clinical benefit achieved has been limited to a subset of patients and tumor types.

The onset, maintenance and development of long-lasting, protective T cell responses are dependent on innate immune cells and NK cells in particular.

Harnessing Innate Immunity in Cancer: NK Cells as a Key Player in the Anti-Tumor Immune Response

NK cells are part of the innate immune system and represent a significant fraction of the total number of cytotoxic cells in the body. They are active in many
hematological and solid tumors and play a key role in the initiation of the T cell response.

Checkpoints expressed on NK cells include inhibitory cell surface receptors, such as NKG2A, and activating NK cell receptors, such as NKp46. NKp46 is
the most specific NK cell marker identified to date across organs and species. Other receptors, such as NKG2A, are more prevalent in certain subsets of NK
cells, including NK cells infiltrating the tumor, and are also present on tumor infiltrating CD8+ T cells.

NK cells are involved in the anti-cancer immunosurveillance through a variety of direct and indirect effects. The figure below provides an illustration of anti-
cancer functions of NK cells.

94

 
 
 
 
 
 
 
 
 
 
 
NK cells are able to directly and selectively kill cells undergoing stress
caused by a cancerous transformation or pathogen infection, a process
called natural cytotoxicity.

NK cells can also kill target cells when they are coated by antibodies in a
process called antibody-dependent cellular cytotoxicity (ADCC).

NK cells are also potent producers of cytokines, which are soluble
molecules that recruit and activate an adaptive immune response by T cells
through dendritic or other antigen-presenting cells, which in turn may
enable the generation of immune memory against tumor cells.

By providing the initial catalyst for the multilayered immune response, the activation of the innate immune system through the targeting of NK cells could
potentially result in an enhanced anti-tumoral T cell response.

The Tumor and its Host: The Immune System and the Tumor Microenvironment

In  recent  years,  the  pursuit  of  understanding  the  resistance  to  immune  checkpoint  inhibitors  has  led  to  an  increased  focus  on  the  TME,  which  plays  an
important role in the inhibition of both the innate and adaptive immune system. The TME contains a complex interplay of immunosuppressive biological
pathways, cells and other components surrounding the tumor that often act together to profoundly suppress the body’s anticancer immune response, thereby
allowing tumors to evade the immune system. More specifically, the TME can inhibit immune responses through the following means:

·

·

·

·

controlling oxygen availability to cells, resulting in hypoxia;

producing or degrading key metabolites regulating cell survival or activation, such as PGE2, adenosine, tryptophan and L-Arginine;

producing immunosuppressive cytokines, such as TGF-ß; and

recruiting suppressive cells such as MDSCs and regulatory T cells.

Our preclinical data has shown that targeting the TME and neutralizing its immunosuppressive, cancer-promoting effects could play a key role in the fight
against cancer in combination with other immunotherapies.

Our Differentiated Approach: Three Pillars to Harness the Potential of the Innate Immune System

Anti-tumor  immune  response  results  from  complex  interactions  between  many  different  cells,  including  innate  immune  cells,  adaptive  immune  cells  and
cancer cells. While T cells, particularly CD8+ T cells, are critical to many protective anti-tumor immune responses, they do not act autonomously and require
the activation of innate immune cells to achieve full potential. More specifically, T cells expand upon the presentation of antigens by activated dendritic cells,
a process that can be enhanced by the activation of NK cells through the production of development factors, chemokines or cytokines. In addition, innate
immune cells can also have anti-tumor activity independent of their impact on T cells and other adaptive immune cells, including for example, the cytotoxic
activity of NK cells.

Our scientific expertise, strategic collaborations and discovery engine allow us to harness the potential of the innate immune system across three pillars:

·

·

·

Broad spectrum immune checkpoint inhibitors. We are targeting checkpoints expressed on several immune system cell types including NK cells
and myeloid cells, rather than focusing solely on T cells, in order to increase the pool of anti-tumor effector cells and potentially mount a larger anti-
tumor response.

Tumor antigen targeting. We are developing antibodies designed to target tumor antigens, in either ADCC-inducing or ADC formats, and unique
antibody-based multi-specific NKCEs, with the goal of combining the direct effect of tumor cell killing with the indirect priming and amplification of
the T cell response by releasing tumor antigens and mobilizing innate immune cells such as NK cells.

Suppressive  factors  of  the  TME.  We  are  developing  product  candidates  that  relieve  the  immunosuppression  of  the  innate  and  adaptive  immune
responses.

Our pipeline is balanced between these three pillars and each pillar is designed to harness the potential of the innate immune system. More specifically, for
each of these pillars, we are advancing the following innovative approaches:

The targeting of inhibitory checkpoints includes the generation of broad-spectrum immune checkpoint inhibitors, such as monalizumab, that have been
designed to unleash several immune cell types such as NK cells and CD8+ T cells. By unleashing both types of cells, broad spectrum immune checkpoint
inhibitors may provide a more effective anti-tumor response when combined with other therapies.

One of the greatest advances in immuno-oncology has been the development of antibodies that target T cell checkpoints, most notably the CTLA-4 and PD-
1/PD-L1 pathways. These treatments have shown an ability to activate T cells, shrink tumors and improve patient survival in a broad range of tumors. In
2011, Yervoy (ipilimumab, anti-CTLA4) became the first checkpoint inhibitor approved by the FDA, followed by Opdivo (nivolumab, anti-PD-1) in 2014
and Keytruda (pembrolizumab, anti-PD-1) in 2015. Other recently approved checkpoint inhibitors include Tecentriq (atezolizumab, anti-PD-L1), Bavencio
(avelumab,  anti-PD-L1),  Imfinzi  (durvalumab,  anti-PD-L1)  and  Libtayo  (cemiplimab,  anti-PD-1).  However,  the  breadth  and  durability  of  clinical  benefit
achieved has been limited to a subset of patients and tumor types.

We are developing broad spectrum checkpoint inhibitors targeting inhibitory checkpoints expressed on several cell types in order to potentially increase the
breadth  and  quality  of  anti-tumor  response.  Our  most  advanced  checkpoint  inhibitor  product  candidate,  monalizumab,  is  a  potentially  first-in-class,  dual
checkpoint inhibitor designed to activate both tumor-infiltrating NK cells and CD8+ T cells, potentially resulting in increased effector functions and greater
killing of the tumor by the immune system. Our preclinical data provide evidence for this dual mechanism of action, the potential of this approach to induce
long-lasting  anti-tumoral  immunity  when  combined  with  PD-(L)1  blockers  and  the  ability  to  increase  the  activity  of  ADCC  inducing  tumor-targeting
antibodies such as cetuximab. Our preclinical checkpoint inhibitor programs include a program targeting Siglec-9 receptors, which is expressed on tumor-
infiltrating  T  cells,  NK  cells  and  innate  myeloid  cells.  We  also  plan  to  continue  to  discover  and  explore  the  potential  of  developing  other  novel  broad
spectrum checkpoint inhibitors.

Targeting tumor antigens, including innovative first-in-class antibody-derived drug candidates such as NKCEs, to harness the anti-tumor activity of NK
cells.

Antigen-targeting  antibody  development  is  highly  dependent  upon  several  factors,  including  the  pattern  of  expression  of  the  target  and  the  intended
mechanism of action. For example, to be effective through ADCC, antibodies should be used in an immunocompetent setting, whereas to be effective by
disrupting a signal, antibodies should target a driver of the oncogenic process. We are targeting tumor antigens that are generally highly-expressed in tumor
tissues but poorly-expressed in healthy tissues in order to develop product candidates through three approaches:

·

The first approach is to directly kill tumor cells using either an ADC, such as with our IPH43 program or an immunotoxin, such as our commercial-
stage product Lumoxiti. This approach is particularly well suited when the tumor bed is not sufficiently infiltrated by immune cells.

97

 
 
 
 
 
 
 
 
 
 
·

·

The  second  approach  is  to  develop  antibodies  that  activate  cells  of  the  innate  immune  system,  such  as  NK  cells,  that  favor  an  immune-mediated
mechanism  of  action.  Our  most  advanced  product  candidate  that  utilizes  this  approach  is  lacutamab,  a  potentially  first-in-class  antibody  targeting
KIR3DL2. Lacutamab seeks to induce tumor killing through ADCC, and we are developing lacutamab for the treatment of various forms of TCL,
such as CTCL, including its aggressive subtype, Sézary syndrome, and PTCL.

The  third  approach  is  to  develop  multi-specific  antibodies  that  leverage  an  activating  checkpoint,  NKp46.  Our  multi-specific  antibodies  co-engage
both  NKp46,  with  or  without  CD16,  and  the  tumor  antigen.  This  approach  has  the  potential  to  more  effectively  mobilize  NK  cells  because,  in  the
TME  of  many  solid  tumors,  CD16,  the  receptor  mediating  the  ADCC  of  antibodies,  can  be  downregulated  on  NK  cells  and  whereas  NKp46
expression is conserved on tumor-infiltrating NK cells. We are currently pursuing this innovative approach for two undisclosed targets with Sanofi and
for one undisclosed target with AstraZeneca. We believe that bridging innate effector cells with the tumor antigen through a multi-specific molecule
has  the  potential  to  overcome  limitations  of  current  strategies  focused  on  artificially  redirecting  T  cells  towards  the  tumors,  either  with  chimeric
antigen receptor (CAR) T cells or T cell engagers. Although these current strategies have had significant success in certain hematologic malignancy
indications, they are often associated with serious adverse events including cytokine release syndrome and neurologic complications. Data from our
preclinical studies suggest that NKCEs are not associated with inflammatory cytokine release and exhibit anti-tumoral activity in solid tumor mouse
models, providing a rationale to investigate the impact of NKCE in patients beyond hematologic malignancies.

Targeting the immunosuppressive TME to render it more immuno-competent through the disruption of the adenosine pathway, such as with IPH5201,
an anti-CD39, and with IPH5301, an anti-CD73, and the complement pathway, such as with avdoralimab, an anti-C5aR.

We are also focusing our development on the role of the TME in suppressing anti-tumoral immunity. The TME can inhibit both innate and adaptive immune
responses by producing or degrading key metabolites or by recruiting suppressive cells, or both. Adenosine is one of the components of the TME that most
broadly affects immune response. It is produced by the sequential degradation of extracellular adenosine triphosphate, or ATP, by two enzymes: first CD39,
which degrades the ATP into adenosine monophosphate, or AMP, and then CD73, which impairs the AMP into adenosine. For this reason, this pathway has
attracted  significant  development  efforts  that  have  been  focused  primarily  on  the  downstream  part  of  the  adenosine  degradation  cascade,  CD73  and  the
adenosine receptors. We are developing a potentially best-in-class anti-CD73 antibody, and have also focused on the upstream part of the cascade, CD39, in
order to block the production of immunosuppressive adenosine and increase the pool of immuno-stimulatory extracellular ATP. We believe this approach is
also  potentially  mechanistically  synergistic  with  many  therapies,  particularly  with  our  checkpoint  inhibitor  and  tumor-targeting  product  candidates  and
programs.

One of the most abundant cell populations within the TME is the myeloid cell subset. Increasing evidence shows that MDSCs accumulate in most individuals
with cancer, where they promote tumor progression, inhibit anti-tumor immunity and are an obstacle to many cancer immunotherapies. Additionally, data
from  mouse  models  suggests  that  chronic  inflammation  and  complement  pathway  activation  eventually  promotes  an  immuno-suppressive  TME  through
MDSCs that impair anti-tumor T cell response and chemotherapy efficacy. In particular, one of the complement proteins, referred to as C5a, can be produced
at the tumor bed where it attracts and activates MDSCs. Our anti-C5aR program, designed to block the migration and activation of MDSCs, is an opportunity
to test a differentiated approach targeting this cell population in cancer. In inflammation, the role of the C5a/C5aR pathway is well established and other
companies are currently exploring the efficacy of blockers in several rare, inflammatory diseases. Other neutrophil-driven more frequent diseases such as
sepsis, acute lung injury, ischemia-reperfusion injury and asthma, offer the possibility of exploring a scientifically validated pathway in these conditions.

Our Product Pipeline

Monalizumab, a Dual Checkpoint Inhibitor Targeting T Cells and NK Cells

Overview and Mechanism of Action

We  are  developing  monalizumab,  a  humanized  IgG4  monoclonal  antibody  targeting  NKG2A,  in  collaboration  with  AstraZeneca.  Monalizumab  is  being
investigated  for  the  treatment  of  SCCHN,  CRC  and  other  tumor  types.  NKG2A  is  an  inhibitory  receptor  that  is  expressed  on  a  subset  of  peripheral  and
tumor-infiltrating NK cells and tumor-infiltrating cytotoxic CD8+ T cells. Monalizumab acts to block the binding of NKG2A to its ligand, HLA-E, which is
overexpressed in many tumors and is often associated with a poor prognosis. Monalizumab enables NK cells and CD8+ T cells to kill cancer cells despite
expression of HLA-E, thereby promoting effector T cell responses in combination with an anti-PD-(L)1 antibody and enhancing NK cell effector functions
and ADCC. The following illustration provides an overview of monalizumab’s mechanism of action:

As  depicted  above,  in  the  absence  of  a  blockade  by  monalizumab,  the  inhibitory  receptor  NKG2A  recognizes  its  ligand,  HLA-E,  on  the  tumor  cell.  This
recognition inhibits or diminishes the activity of the NK cell and CD8+ T cell against the tumor cell because the inhibitory signal from the NKG2A receptor
counterbalances  the  signal  of  the  activating  receptors,  shown  in  green  in  the  illustration  above.  When  NKG2A  is  blocked  from  recognizing  its  ligand  by
monalizumab,  the  signal  from  the  activating  receptors  can  prevail  and  thereby  trigger  the  NK  cell  and  CD8+  T  cell  to  eliminate  the  cancerous  cells.
Activation of NK cells at the tumor site appears to initiate the sequence of immune events that allows tumors to be detected and killed by CD8+ T cells
through a combination of direct cytotoxicity and the promotion of adaptive responses by inducing recruitment of dendritic cells that present tumor antigens
via MHC-I on the surface of those cells.

99

 
 
 
 
 
 
 
 
 
Development Strategy and Opportunity

The expression of HLA-E in several cancer types suggests that it plays a key role in suppressing or inhibiting an immune response to the tumor, thereby
allowing tumor progression. HLA-E is expressed in 70-90% of patients with SCCHN, CRC, cancers of the ovary, endometrium, cervix and lung, and various
types of leukemia and lymphoma, as well as in up to 50% of all cases of melanoma and esophageal cancers. We are evaluating monalizumab in clinical trials
in collaboration with AstraZeneca in multiple advanced solid tumors. Currently, the most advanced clinical programs are for the treatment of SCCHN and
CRC.

SCCHN accounts for approximately 4% of all cancers in the United States. The American Cancer Society estimates that in 2020, over 65,500 Americans will
develop head and neck cancer and over 14,500 will die from the disease. The survival rate in patients with SCCHN varies greatly depending on the stage of
the cancer at diagnosis. Among patients with more advanced disease (stages III and IV), up to 50% develop locoregional relapses and/or distant metastases.
Once this occurs, the five-year survival rate drops significantly. Cetuximab (marketed as Erbitux), an EGFR inhibitor, and anti-PD-1 checkpoint inhibitors,
including nivolumab (marketed as Opdivo) and pembrolizumab (marketed as Keytruda), have been approved by the FDA for the treatment of SCCHN in the
second  line  setting.  However,  many  patients  continue  to  fail  to  respond  to  these  treatments  and  patients  with  SCCHN  who  have  received  prior  immuno-
oncology treatments have few treatment options and represent a group with a significant unmet medical need.

CRC is the third most common cancer in men and the second most common cancer in women globally. The American Cancer Society estimates that in 2020,
over 148,000 Americans will develop CRC and over 53,000 will die from the disease. The five-year survival rate varies greatly depending on the stage of the
cancer: for localized colorectal cancer, the five-year survival rate is as high as 90%, but if the cancer has metastasized, the five-year survival rate drops to less
than 15%. Patients with metastatic CRC typically receive multi-agent chemotherapy with or without antiangiogenic therapy. Approximately 50% of CRC
patients have a mutation of the KRAS oncogene. Patients without this mutation typically receive an EGFR inhibitor. With these regimens, median overall
survival reaches 30 months, but the five-year survival rate is less than 15%. If these treatments fail, patients may receive third and later lines of treatment,
such as regorafenib (marketed as Stivarga) and the trifluridine/tipiracil combination (marketed as Lonsurf). While both of these drugs have been approved by
the FDA, their response rate is less than 5% and overall survival was observed to be longer than placebo by less than two months. More substantial activity
has been reported for checkpoint inhibitors in patients with the microsatellite instable, or MSI, subtype of CRC, referred to as MSI-CRC. However, the MSI
subtype comprises only 5-15% of all CRC cases. Among the 85-95% of CRC patients with the microsatellite stable, or MSS, subtype of CRC, referred to as
MSS-CRC, patients in the third and later lines of treatment represent a significant unmet medical need.

100

 
 
 
 
 
 
 
We are primarily focused on investigating monalizumab in combination with other approved anti-cancer agents, including:

·

·

Cetuximab, an antibody directed against EGFR, is used for the treatment of metastatic CRC and SCCHN. In preclinical models, cetuximab has been
observed  to  bind  to  EGFR  on  tumor  cells  and  thereby  trigger  ADCC  by  NK  cells.  However,  the  efficacy  of  ADCC  is  inhibited  by  NKG2A
engagement  with  HLA-E.  Our  preclinical  data  support  our  hypothesis  that  monalizumab,  by  blocking  the  binding  of  NKG2A  to  HLA-E,  could
enhance the therapeutic activity of cetuximab.

Durvalumab  is  an  antibody  directed  against  PD-L1.  PD-L1  and  HLA-E  are  both  up-regulated  on  many  cancer  cells,  and  they  have  both  been
observed to suppress tumor immune response and contribute to tumor progression. Our preclinical data support our hypothesis that a monalizumab
and durvalumab combination therapy may result in a greater anti-tumor immune response than durvalumab alone by blocking both the PD-1/PD-L1
and the NKG2A/HLA-E inhibitory pathways.

The specificity of the combination of cetuximab and monalizumab is produced by the dual targeting of both activating receptors and inhibitory receptors.
Immune  checkpoint  inhibitors  unleash  lymphocytes  by  blocking  inhibitory  receptors  and  rely  on  endogenous  activating  receptors  expressed  on  these
lymphocytes to mediate the attack of the tumor cells. In contrast, we believe the combination of cetuximab and monalizumab will not only unleash NK cells
by blocking the inhibitory function of NKG2A, but also trigger NK cell cytotoxicity via the recognition of cetuximab-coated tumor cells through the CD16
receptor. The following illustration depicts the way in which monalizumab, in combination with cetuximab or durvalumab, is designed to result in greater
anti-tumor activity.

101

 
 
 
 
 
 
 
 
The rationale for these combinations is further supported by the favorable tolerability profile of monalizumab that we observed in preclinical studies and
earlier clinical trials, suggesting that monalizumab is generally not expected to negatively impact the safety profile of the combination partner drugs.

The  safety  of  monalizumab  was  investigated  by  Novo  Nordisk  in  two  Phase  I  trials  in  patients  with  rheumatoid  arthritis  and  one  Phase  I/II  dose-ranging
monotherapy trial in advanced, heavily pretreated ovarian cancer patients. Although short in duration and in a different patient population, the rheumatoid
arthritis  trial  provided  valuable  dose  escalation  data  that  we  were  able  to  leverage  in  order  to  accelerate  development  of  monalizumab  in  oncology
indications.  In  a  dose-ranging  trial  performed  by  NCIC  in  patients  with  ovarian  cancer,  18  patients  were  randomized  to  three  monalizumab  treatments
groups:  1  mg/kg,  4  mg/kg  and  10  mg/kg.  Monalizumab  was  well  tolerated  in  each  of  the  three  groups  with  no  dose  limiting  toxicities,  or  DLTs,  and  no
serious adverse events, or SAEs, reported. The most frequent adverse events, or AEs, were headache, fatigue, dry mouth, nausea/vomiting, hot flashes and
arthromyalgia. In this trial, the only AEs equal or above grade 3 were two cases of fatigue, three cases of nausea/vomiting and one case of dehydration. There
was no observed dose relationship between AEs and dosage of monalizumab.

Under our collaboration agreement with AstraZeneca, we are eligible to receive a $100 million milestone payment upon dosing of the first patient in the first
Phase III clinical trial for monalizumab. AstraZeneca has advised us that it expects to commence the Phase III clinical trial of monalizumab in combination
with cetuximab in 2020.

Phase Ib/II Clinical Trial in Relapsed/Metastatic SCCHN (in combination with cetuximab)

We and AstraZeneca are currently evaluating monalizumab in an open-label, Phase Ib/II clinical trial in combination with cetuximab in patients with R/M
SCCHN.  The  trial  is  currently  being  conducted  at  five  sites  in  the  United  States  pursuant  to  an  investigational  new  drug  application,  or  IND,  that  was
accepted  by  the  FDA  in  August  2015,  and  in  nine  sites  in  France,  where  it  was  approved  by  the  Agence  Nationale  de  la  Sécurité  du  Médicament  et  des
Produits de Santé, or ANSM, in September 2015. The trial is expected to enroll up to 140 patients. The following graphic shows the trial design:

In the Phase Ib dose-escalation portion of the clinical trial, 17 patients with R/M SCCHN were evaluated across five dose levels of monalizumab (0.4, 1.0,
2.0, 4.0 and 10.0 mg/kg), administered every two weeks, in combination with cetuximab, administered intravenously with an initial dose of 400 mg/m2 and
subsequent doses of 250 mg/m2. For the Phase Ib dose-escalation portion of the trial, the primary endpoint was to assess the occurrence of DLTs in order to
determine the recommended dose level of monalizumab for the Phase II portion of the trial. The secondary endpoint was objective response rate, which is
measured as the rate of patients who had a complete or partial response according to RECIST 1.1, a widely used guideline to measure anti-tumor response in
oncology. The response categories defined under RECIST 1.1 are summarized in the table below.

Seventeen patients were enrolled in the dose escalation portion of the Phase Ib trial. Two patients were not evaluable for DLTs as they withdrew from the trial
within  three  weeks  of  first  treatment  for  reasons  other  than  DLTs.  In  the  15  evaluable  patients,  no  DLTs,  infusion-related  reactions  or  immune-related
disorders were observed, and no discontinuations from the trial attributable to treatment-related AEs or treatment-related deaths occurred. The combination
was reported to be well tolerated with no AEs beyond those observed with monalizumab or cetuximab administered as monotherapies. The most common
treatment-related AEs were asthenia/fatigue (24%) and headache (18%). All AEs related to treatment with monalizumab were grade 1 or 2 except for one
case of grade 3 fatigue experienced by a patient in the 0.4 mg/kg treatment group. Based on the results observed in the Phase Ib dose- escalation portion of
the trial, the recommended Phase II dose of monalizumab, in combination with cetuximab, was established as 10 mg/kg, administered intravenously every
two weeks.

The primary endpoint for the Phase II portion of the trial is objective response rate, which is measured as the rate of patients who had a complete or partial
response  according  to  RECIST  1.1.  Secondary  endpoints  for  the  Phase  II  portion  of  the  trial  include  duration  of  response,  progression-free  survival  and
overall survival. The Phase II portion of the trial is comprised of three expansion cohorts:

·

·

·

Expansion Cohort 1, which enrolled 40 patients, evaluated the combination of monalizumab and cetuximab in patients with R/M SCCHN who had
been previously treated with chemotherapy alone or chemotherapy followed by checkpoint inhibitors;

Expansion Cohort 2, which enrolled 40 patients and is evaluating the combination of monalizumab and cetuximab in patients with R/M SCCHN who
have received a maximum of two prior systemic regimens in the R/M setting and with prior exposure to a PD-(L)1 inhibitor (who we refer to as IO-
pretreated patients); and

Expansion Cohort 3, which is expected to enroll up to 40 patients, began recruiting in April 2019 and is evaluating the combination of monalizumab,
cetuximab and durvalumab in IO-naïve patients with R/M SCCHN.

Preliminary clinical efficacy data from the first expansion cohort was presented at the American Association for Cancer Research, or AACR, 2018 annual
meeting and at the ESMO 2018 annual meeting. Further subset analyses were presented at the 2018 annual meeting of the Society for Immunotherapy of
Cancer and updated one-year survival data was presented at the ESMO 2019 annual meeting. As of April 30, 2019 a total of 40 patients with R/M SCCHN
were  evaluable  for  safety.  Thirty-nine  patients  were  evaluable  for  efficacy,  while  one  patient  was  not  evaluable  for  efficacy  because  of  fatal  tumor
progression.

The following tables summarize the efficacy results as of April 30, 2019.

Although preliminary, the activity of the monalizumab and cetuximab combination appears to occur across Human Papillomavirus, or HPV, status, tumor
burden and PD-(L)1 expression. We believe our preliminary results of the monalizumab and cetuximab combination are encouraging when viewed in light of
the clinical results of currently approved treatment options for R/M SCCHN:

Cetuximab was approved by the FDA for patients previously treated with platinum-based chemotherapy on the basis of a single-arm Phase II clinical
trial  in  which  patients  treated  with  cetuximab  achieved  an  overall  response  rate  of  12.6%,  median  time  to  progression  of  2.3  months  and  overall
survival of 5.8 months.

Pembrolizumab was approved by the FDA for the treatment of patients previously treated with platinum-based chemotherapy on the basis of a single-
arm Phase II clinical trial (KEYNOTE-012) in which patients treated with pembrolizumab achieved an overall response rate of 16.0% and median
overall survival of 8.4 months. The median follow-up time was 8.9 months. Among the 28 responding patients, the median duration of response had
not been reached (range: 2.4+ to 27.7+ months), with 23 patients having responses of six months or longer.

Nivolumab was approved by the FDA for the treatment of patients previously treated with platinum-based chemotherapy on the basis of a randomized,
active-controlled,  open-label  clinical  trial  (CHECKMATE-141).  Patients  were  randomized  to  receive  nivolumab  or  the  investigator’s  choice  of
cetuximab, methotrexate or docetaxel. Patients treated with nivolumab achieved an overall response rate of 13.3%. Median overall survival was 7.5
and 5.1 months in the nivolumab and investigator’s choice arms, respectively.

Although  we  believe  the  preliminary  results  of  this  trial  are  promising,  no  definitive  conclusions  regarding  safety  or  effectiveness  can  be  drawn  from
historical comparisons between this trial and those of the approved drugs discussed above due to the development stage of monalizumab, differences in trial
designs and other factors.

Of the 40 patients evaluable for safety in the first expansion cohort of our Phase II trial as of April 30, 2019, all experienced one or more treatment-emergent
adverse events, or TEAEs; half of the patients experienced grade 3 or 4 TEAEs. Thirty (75%) patients experienced TEAEs deemed to be related to treatment
with monalizumab, and of these, eight (20%) patients experienced grade 3 or 4 related TEAEs. Of the 40 evaluable patients, 16 (40%) patients experienced
SAEs and 12 (30%) experienced grade 3 or 4 SAEs. Of these patients, three (8%) experienced SAEs deemed to be related to treatment with monalizumab (all
grade  3  or  4).  These  SAEs  consisted  of  colitis,  interstitial  lung  disease  and  hypophosphatemia.  Only  one  patient  discontinued  treatment  due  to  an  AE.
Cetuximab  monotherapy  is  associated  with  significant  toxicity.  In  the  pivotal  clinical  trial  of  cetuximab  in  SCCHN,  AEs  were  reported  for  99%  of  the
patients and SAEs, mostly grade 3 or 4, were reported in 46% of the 47 patients. The most common cetuximab-related AEs were rash, acne and asthenia. In
our trial investigating the monalizumab and cetuximab combination, there has been no indication to date that the addition of monalizumab has a negative
impact on the tolerability of cetuximab or vice-versa, consistent with the favorable tolerability profile of monotherapy observed in prior preclinical studies
and clinical trials to date.

We  expect  to  report  preliminary  data  from  the  second  cohort  expansion  in  the  first  half  of  2020.  We  believe  that  data  from  the  second  cohort  expansion
testing  monalizumab  in  combination  with  cetuximab  in  patients  having  been  treated  by  a  previous  line  of  PD-(L)1  will  inform  the  next  steps  of  the
development  of  the  combination.  We  estimate  that  there  are  approximately  15,000  patients  that  have  received  at  least  two  prior  lines  of  treatment  in  the
United States, Europe, Japan and China. We also believe that there will be a paradigm shift in the frequency and stage of use for anti-PD-(L)1 treatments,
which we believe will be utilized more frequently in earlier lines of treatment.

107

 
 
 
 
 
 
 
 
 
The third expansion cohort was initiated in April 2019 and will provide initial data in IO-naïve patients. We expect to have preliminary data for the third
expansion cohort in the second half of 2020. We believe these data will inform the design of potential future clinical trials in early settings, such as the first
line or locally advanced setting. We estimate that in the United States, Europe, Japan and China, there are approximately 65,000 and 40,000 patients in the
first line and locally advanced settings, respectively.

On September 26, 2019, we announced that AstraZeneca will advance monalizumab into a Phase III randomized clinical trial evaluating monalizumab in
combination with cetuximab in patients suffering from R/M SCCHN, and that we and AstraZeneca will co-fund the clinical trial. The initiation of the clinical
trial is expected in 2020, subject to regulatory and compliance approvals.

Phase I/II Clinical Trial in Solid Tumors, including Colorectal Cancer (in combination with durvalumab)

AstraZeneca is evaluating monalizumab in a Phase I/II, multi-center, single-arm, 3+3 dose-escalation and cohort expansion clinical trial in combination with
durvalumab in up to 381 adults with advanced solid tumor malignancies, including CRC. This trial, which commenced in February 2016, is being conducted
at 28 sites in the United States pursuant to an IND that was accepted by the FDA in January 2016, as well as over 40 sites in Australia, Belgium, Brazil,
Canada,  France,  Hungary,  Italy,  South  Korea,  New  Zealand,  Spain  and  the  United  Kingdom.  The  primary  endpoint  of  the  trial  is  safety,  with  anti-tumor
efficacy being a key secondary endpoint. Other secondary endpoints include response duration, progression-free survival, overall survival, pharmacokinetics,
pharmacodynamics, and immunogenicity of a monalizumab and durvalumab combination.

In  June  2018,  at  the  annual  meeting  of  the  American  Society  of  Clinical  Oncology,  or  ASCO,  the  trial  investigators  presented  clinical  data  showing
preliminary  anti-tumor  activity  in  patients  with  R/M  MSS-CRC,  a  population  historically  unresponsive  to  PD-(L)1  blockade.  At  the  most  recent
measurement date in April of 2018, 40 patients were evaluable for safety and 39 were evaluable for efficacy. Thirty-five (88%) patients had two or more prior
lines of therapy. The key efficacy data from this Phase I/II clinical trial are summarized in the table below.

Clinical results of the currently approved treatment options for R/M MSS-CRC, regorafenib and trifluridine, are as follows:

·

·

Regorafenib (marketed as Stivarga) was approved by the FDA for the treatment of patients who have been previously treated with chemotherapy, an
anti-vascular endothelial growth factor, or VEGF, therapy and, if KRAS wild type, an anti-EGFR therapy, based on a randomized, placebo-controlled
Phase III clinical trial. In this trial, patients with metastatic CRC who were treated with regorafenib achieved an overall response rate of 1%. Median
overall survival was 6.4 months in the regorafenib group versus 5.0 months in the placebo group. Progression-free survival was 2.0 months in the
regorafenib group versus 1.7 months in the placebo group, and 41% of patients in the regorafenib group achieved disease control compared to 15% in
the placebo group.

Trifluridine/tipiracil combination (marketed as Lonsurf) was approved by the FDA for the treatment of patients who have been previously treated with
the same prior treatments as regorafenib, based on a randomized, placebo-controlled Phase III clinical trial. Patients treated with trifluridine/tipiracil
combination achieved an overall response rate of 1.6%. Median overall survival was 7.2 months in the trifluridine/tipiracil combination group versus
5.2 months in the placebo group. Progression-free survival was 2.0 months in the trifluridine/tipiracil combination group compared to 1.7 months in
the placebo group.

These  data  indicate  that  there  remains  a  significant  medical  need  for  metastatic  CRC  in  the  third  or  later  line  setting  with  response  rates  to  available
treatments of less than 5% and median overall survival only minimally exceeding that seen with placebo.

The safety results of the monalizumab and durvalumab combination from this trial have been consistent with the monotherapy profiles of each agent. Dose-
escalation was completed with no DLTs and the maximum tolerated dose was not reached. No fatal AEs or AEs leading to treatment discontinuation were
reported. In the MSS-CRC expansion cohort, the most common treatment-related AEs included arthralgia (7.5%), increased levels of alkaline phosphatase, or
AST (7.5%), hypothyroidism (7.5%), pruritus (7.5%) and rash (7.5%). Grade 3 or 4 AEs that occurred in three patients were limited to one case each of
sepsis (grade 4) and increased lipase (grade 3), that both were resolved, and increased AST (grade 3).

Based in part on the clinical trial results observed to date, AstraZeneca has decided to pursue additional expansion cohorts to assess the safety and efficacy of
monalizumab in combination with durvalumab in first and third line settings in treating metastatic CRC. These additional expansion cohorts are ongoing.

At the ESMO 2019 annual meeting, data were presented from a dose-exploration cohort assessing the safety and efficacy of durvalumab and monalizumab in
combination with standard of care chemotherapy (bevacizumab and modified folinic acid, fluorouracil and oxaliplatin, or mFOLFOX6) as a first-line therapy
for advanced and metastatic MSS-CRC. Eligible patients with MSS-CRC had at least one lesion measurable by RECIST 1.1, adequate coagulation and organ
function and no prior systemic therapy. Patients received 1500 mg of durvalumab intravenously every four weeks, 750 mg of monalizumab every two weeks,
mFOLFOX6  every  two  weeks,  and  5  mg/kg  of  bevacizumab  every  two  weeks.  Treatment  continued  until  unacceptable  toxicity  or  confirmed  progressive
disease was observed, or due to patient withdrawal for other reasons. Chemotherapy dose modifications were allowed according to standard of care practices,
except  during  the  dose-limiting  toxicity  evaluation  period.  The  primary  objective  was  to  assess  the  safety  and  tolerability  of  the  combination  therapy;
secondary endpoints included anti-tumor activity.

As of July 29, 2019, 18 patients were enrolled in the dose-exploration expansion cohort. The combination of monalizumab, durvalumab, standard of care
chemotherapy and bevacizumab had no DLTs and a safety profile as a first-line therapy for advanced and metastatic MSS-CRC that was similar to that of the
standard of care alone. Of the 18 patients in the clinical trial, 17 patients were evaluable for response.

TEAEs  relating  to  monalizumab  occurred  in  14  patients  (77.8%),  with  the  most  common  TEAEs  being  fatigue  (27.8%)  and  increased  aspartate
aminotransferase  (16.7%).  One  patient  had  a  grade  3  AE  (embolism),  a  TEAE  that  was  also  considered  to  be  related  to  chemotherapy  and  bevacizumab
treatment.

Durvalumab-related TEAEs occurred in 15 patients (83.3%), most commonly fatigue (27.8%), increased amylase (22.2%) and increased lipase (22.2%). No
patients had SAEs that were determined to be durvalumab-related.

All patients had chemotherapy-related TEAEs, most commonly fatigue (55.6%), nausea (55.6%) and peripheral neuropathy (50.0%). Two patients (11.1%)
had chemotherapy-related, grade 3 SAEs, which were comprised of embolism and febrile neutropenia.

Bevacizumab-related AEs occurred in 10 patients (55.6%), and were most commonly epistaxis (16.7%), fatigue (16.7%), increased lipase (11.1%) and rash
(11.1%). Two patients (11.1%) had bevacizumab-related, grade 3 SAEs, which were comprised of embolism and febrile neutropenia.

In January 2020, AstraZeneca presented updated data as of August 26, 2019 at the Gastrointestinal Cancer Symposium (ASCO GI). Such data was identical
as the data presented above.

We expect AstraZeneca will use clinical trial data observed to date to inform the design of potential future clinical trials in CRC.

Additional Exploratory Clinical Trials

Monalizumab is also being evaluated by us, AstraZeneca and investigator sponsors in several exploratory trials:

·

·

AstraZeneca’s  two  clinical  trials  in  NSCLC.  AstraZeneca  is  conducting  two  separate  Phase  II  clinical  trials  assessing  the  efficacy  and  safety  of
durvalumab monotherapy as compared to durvalumab in combination with various novel agents, including monalizumab, in NSCLC. The first trial is
expected to enroll up 60 patients with unresectable, stage III NSCLC and the second trial is expected to enroll 20 patients with resectable NSCLC. The
primary endpoint of the first trial is objective response rate at 16 weeks according to RECIST 1.1, and secondary endpoints include incidence of AEs,
duration of response, disease control and progression-free survival. The primary endpoint of the second trial is major pathological response rate and
key secondary endpoints include safety and pathological complete response rate. These trials began in January 2019 and are being conducted in the
United States, Canada, France, Hong Kong, Italy, Poland, Portugal, Spain, Switzerland and Taiwan.

AstraZeneca’s  clinical  trial  in  MSS-CRC  (Columbia  2).  AstraZeneca  is  conducting  a  Phase  II  clinical  trial  assessing  the  efficacy  and  safety  of
standard-of-care adjuvant mFOLFOX6 chemotherapy alone or in combination with novel oncology therapies, including monalizumab. The study will
be conducted in subjects who have undergone radical surgical resection for Stage II or III MSS-CRC, are eligible for mFOLFOX6 adjuvant therapy,
and are confirmed as circulating tumor DNA (ctDNA) positive post-surgery. The primary endpoint of the trial is ctDNA clearance, which is defined as
the change from ctDNA positive status at baseline to ctDNA negative post baseline (6 months). Key secondary endpoints include incidence of AEs,
disease free survival, disease free survival at 12 months, overall survival and pharmacokinetics and immunogenicity. We expect the trial to start at the
end of April 2020 and to be conducted in the United States, Australia, Canada, France, the Republic of Korea, Spain and Taiwan.

The PIONeeR clinical trial, a Phase II clinical trial sponsored by Marseille Public University Hospital System. The purpose of this trial is to assess
how to overcome resistance to immune checkpoint inhibitor monotherapies with experimental precision immunotherapies combined with durvalumab
in third or fourth line treatment, in patients with advanced NSCLC. The PIONeeR trial includes multiple trial arms, each testing a different therapy in
combination with durvalumab. In the monalizumab arm, up to 30 patients will receive durvalumab in combination with 750 mg of monalizumab every
four weeks. The 12-week disease control rate is the primary endpoint, and there are multiple key secondary endpoints including overall response rate,
progression-free survival, overall survival and duration of response. The trial is being conducted in France.

Phase I clinical trial evaluating monalizumab as a single agent in patients with hematological malignancies in a post-transplantation setting sponsored
by Institut Paoli-Calmettes. The objective of this trial is to identify the maximum tolerated dose, if any, and to select a recommended Phase II dose in
this  particular  population.  The  trial  will  enroll  up  to  18  patients  and  will  include  patients  who  have  received  allogenic  hematopoietic  stem  cell
transplantation. Four sequential cohorts of patients will receive a single escalating dose of monalizumab 75 to 100 days after stem cell transplantation.
The primary endpoint is the occurrence ratio of DLTs within four weeks of treatment. Secondary endpoints include incidence of acute and chronic
graft-versus-host disease, probabilities of non-relapse mortality, cumulative incidence of relapse, probability of disease-free survival and probability of
overall survival, each measured at one year after administration of monalizumab. This trial began in December 2016 and is being conducted in France.

Phase II clinical trial evaluating monalizumab in patients with R/M SCCHN sponsored by the European Organisation for Research and Treatment for
Cancer.  The  objective  of  this  trial  is  to  evaluate  biomarker-based  treatment  of  patients  with  R/M  SCCHN.  The  trial  groups  patients  into  different
biomarker-driven cohorts, each receiving a different study drug. Monalizumab will be evaluated in a single arm Phase II cohort of approximately 40
patients who are anti-PD-(L)1 naïve or resistant. The primary endpoints of the trial are progression-free survival at 16 weeks and objective response
rate  at  six  months.  Secondary  endpoints  include  progression-free  survival,  response  duration,  overall  survival  and  toxicity,  each  measured  at  54
months after first patient in, as well as objective response rate measured at 48 months after first patient in. The trial began in March 2017 and is being
conducted  in  Belgium,  France,  Italy  and  the  United  Kingdom.  Preliminary  clinical  trial  results  were  presented  at  the  2019  ESMO  annual  meeting,
which  showed  that  monalizumab  had  limited  activity  as  a  monotherapy  for  the  26  evaluable  patients  with  R/M  SCCHN,  and  it  did  not  meet  its
primary  endpoint  as  a  monotherapy,  with  an  overall  response  rate  of  0%,  stable  disease  in  23%  of  patients  and  a  median  overall  survival  of  6.7
months. The expansion cohort evaluating monalizumab in combination therapy is ongoing.

Phase  II  clinical  trial  evaluating  monalizumab  and  trastuzumab  in  patients  with  metastatic  or  locally  incurable  HER2-positive  breast  cancer
(MIMOSA)  sponsored  by  The  Netherlands  Cancer  Institute.  The  objective  of  this  explorative  trial  is  to  assess  the  efficacy  of  the  combination  in
patients with high stromal tumor-infiltrating lymphocytes (sTILs) or low sTILs in two separate cohorts (higher or equal to 5% versus lower than 5%).
The  primary  endpoint  is  response  rate  according  to  RECIST  1.1.  Secondary  endpoints  include  clinical  benefits  (patients  with  complete  response,
partial  response  or  stable  disease  for  more  than  24  weeks  according  to  RECIST1.1),  PFS,  OS  and  toxicity  (DLT  will  be  monitored  since  the
combination has never been used in trials before).

Lumoxiti, a First-in-Class, Marketed Product In-Licensed from AstraZeneca for the Treatment of Hairy Cell Leukemia

Lumoxiti (moxetumomab pasudotox-tdfk) is a marketed, first-in-class CD22-directed cytotoxin for the treatment of HCL which was approved by the FDA
under priority review in September 2018 as a treatment for adult patients with R/R HCL who have received at least two prior systemic therapies, including
treatment with a purine nucleoside analog, or PNA. Lumoxiti has been granted orphan drug designation by the FDA for the treatment of HCL.

HCL is a rare, chronic and slow-growing leukemia in which the bone marrow over-produces abnormal B cell lymphocytes. Untreated, HCL can result in
serious  conditions,  including  infections,  bleeding,  anemia  and  potentially  may  lead  to  death.  Approximately  1,000  people  are  diagnosed  with  HCL  in  the
United States each year. HCL accounts for up to 3% of all adult leukemias. While many patients initially respond to treatment, approximately 30-40% will
relapse within five to ten years after their first treatment.

PNAs, such as cladribine and pentostatin, are the established first line treatments for patients with HCL. Up to 90% of the patients treated with PNAs achieve
a complete remission. However, PNAs are associated with AEs linked to myelosuppression, which is a condition in which bone marrow activity is decreased,
resulting  in  fewer  red  blood  cells,  and  immunosuppression.  Most  patients  who  relapse  more  than  two  years  after  their  initial  treatments  receive  a  second
course of PNAs with a similar overall response rate to initial therapy but with a shorter duration. Patients who relapse earlier often receive PNAs combined
with rituximab. When a patient relapses a second time, reaching the third line setting, PNAs are less effective, with a significantly lower response rate and
shortened duration of response. The third and later line setting, which we estimate comprises approximately 380 patients in the United States on an annual
basis, represents a significant medical challenge, with no established standard of care and very few treatment options available. The National Comprehensive
Cancer Network, or NCCN, guidelines for HCL, updated in January 2019, recommend that patients who are third line or later in treatment be considered for
Lumoxiti or participate in clinical trials of vemurafenib, with or without rituxan, or ibrutinib. Vemurafenib and ibrutinib have shown limited activity. The
third and later line setting represents a significant medical challenge, with no established standard of care and very few treatment options available. To date,
Lumoxiti is the only approved drug in the United States for those patients in third line or later treatment.

The  approval  of  Lumoxiti  was  based  on  data  from  the  open-label  ‘1053’  trial,  which  was  a  single-arm,  multi-center  Phase  III  clinical  trial  assessing  the
efficacy, safety, immunogenicity and pharmacokinetics of Lumoxiti monotherapy in patients with R/R HCL who had received at least two prior therapies,
including  one  PNA.  The  trial  enrolled  80  patients  and  was  conducted  at  34  sites  in  14  countries.  The  primary  endpoint  was  durable  complete  response,
defined  as  complete  response  with  hematologic  remission  (blood  count  normalization)  for  more  than  180  days.  Secondary  endpoints  included  overall
response  rate,  relapse-free  survival,  progression-free  survival,  time  to  response,  safety,  pharmacokinetics  and  immunogenic  potential.  In  this  trial,  of  the
patients treated with Lumoxiti, 75% achieved an overall response, 30% had a durable complete response and 34% achieved a complete response with no
minimal residual disease. The following table summarizes initial efficacy results of the trial at the primary readout:

Minimal residual disease (MRD) is a term used to describe the small number of cancer cells in the body after cancer treatment. An MRD
positive test result means that disease was still detected after treatment. An MRD negative result means that no disease was detected after
treatment. The MRD status was independently assessed in bone marrow biopsy specimens using immunohistochemistry.

Partial response is defined as ³ 50% decrease or normalization (< 500/mm3) in peripheral blood lymphocyte count, reduction of pre-existing
lymphadenopathy and/or organomegaly, and haematologic remission

The final analysis confirms the acceptable tolerability of Lumoxiti, with low rates of treatment-related AEs leading to discontinuation. The final analysis did
not  identify  any  new  serious AEs  or  change  in  hemolytic  uremic  syndrome  or  capillary  leak  syndrome.  Consistent  with  the  primary  analysis,  the  most
frequent AEs were peripheral edema (39%), nausea (35%), fatigue (34%), headache (33%), and pyrexia (31%). Grade 3 and 4 capillary leak syndrome and
hemolytic uremic syndrome were seen in 2.5% and 7.5% of the patients, respectively. These AEs were reported to be manageable and reversible with close
monitoring and best supportive care.

We  in-licensed  commercial  rights  to  Lumoxiti  in  the  United  States  and  European  Union  from  AstraZeneca  in  2018.  As  part  of  our  agreement  with
AstraZeneca,  we  have  a  collaborative  and  staged  transition  for  the  Lumoxiti  program.  Since  the  end  of  the  fourth  quarter  of  2019,  we  have  become  the
primary  commercial  entity  promoting  Lumoxiti,  having  transitioned  all  sales  and  medical  affairs  activities,  including  medical  science  liaisons  and  sales
representatives, from AstraZeneca to us. We plan to leverage the commercial infrastructure that we are developing for Lumoxiti to commercialize our other
product candidates targeting rare cancers, including lacutamab in Sézary syndrome, MF and PTCL, if approved.

In January 2020, we announced that the European Medicines Agency (EMA) has accepted the Marketing Authorization Application (MAA) submission for
Lumoxiti,  for  the  treatment  of  patients  R/R  HCL  who  have  received  at  least  two  prior  systemic  therapies,  including  treatment  with  a  purine  nucleoside
analog.

Lacutamab (IPH4102), a Tumor Targeting Anti-KIR3DL2 Antibody

Overview and Mechanism of Action

We are developing our wholly owned product candidate lacutamab for the treatment of certain subtypes of TCLs, including CTCL and PTCL. Lacutamab is
designed to bind to the KIR3DL2 receptor and to kill cancer cells by ADCC, as illustrated in the following figure.

116

 
 
 
 
 
 
 
 
 
 
KIR3DL2 is a receptor of the KIR family. In our preclinical studies, we have observed that KIR3DL2 is not expressed on healthy tissues, except on a subset
of NK cells and T cells. In addition, KIR3DL2 is expressed in T-cell lymphoma. In particular, 65% of CTCL patients express KIR3DL2 and KIR3DL2 is
also expressed in approximately 50% of patients with MF, the most common type of CTCL. This frequency increases to 85% for the most aggressive CTCL
subtypes, including Sézary syndrome. KIR3DL2 is also expressed by approximately 50% of patients with PTCL.

In January 2019, the FDA granted lacutamab Fast Track Designation for the treatment of adults with R/R Sézary syndrome who have received at least two
prior  systemic  therapies.  Lacutamab  has  also  been  granted  orphan  drug  designation  in  the  European  Union  and  in  the  United  States  for  the  treatment  of
CTCL. In May 2019, we initiated a Phase II clinical trial evaluating lacutamab in different subtypes of TCL.

Cutaneous T Cell Lymphoma

CTCL is a heterogeneous group of non-Hodgkin’s lymphomas that are characterized by the abnormal accumulation of malignant T cells, primarily in the
skin. CTCL accounts for approximately 4% of all non-Hodgkin’s lymphomas and has a median age at diagnosis of 55 to 65 years. There are approximately
6,000  new  CTCL  cases  diagnosed  per  year  in  Europe  and  the  United  States  combined.  The  most  common  type  of  CTCL  is  mycosis  fungoides,  or  MF,
accounting for approximately half of all CTCLs. Sézary syndrome, characterized by the presence of lymphoma cells in the blood, is a CTCL subtype with a
particularly poor prognosis. The following table outlines the most common CTCL types, their frequency as a percentage of all cases of CTCL, and prognosis.

Patients  with  advanced  CTCL  have  a  poor  prognosis  with  few  therapeutic  options  and  no  standard  of  care.  Treatment  generally  includes  skin-directed
therapies, such as topical corticosteroids, and systemic treatments, such as steroid drugs and interferon, for patients with more advanced disease or for whom
skin-directed therapies failed.

Two new drugs have recently been approved for the treatment of CTCL:

·

·

Brentuximab vedotin (marketed as Adcetris), has been approved by the FDA for treatment of patients with primary cutaneous anaplastic large cell
lymphoma,  or  pcALCL,  or  CD30-expressing  MF  who  have  received  prior  systemic  therapy.  In  Europe,  brentuximab  vedotin  is  indicated  for  the
treatment of adult patients with R/R CD30+ CTCL who require systemic therapy. The response rate to brentuximab vedotin was 67% compared to
20%  in  the  control  group  (physician’s  choice  of  either  methotrexate  or  bexarotene)  and  the  median  progression-free  survival  was  16.7  months
compared to 3.5 months for the control group. Brentuximab vedotin was associated with a 45% risk of peripheral neuropathy, which led to treatment
discontinuation in 12% of the patients and inclusion of a boxed warning on the label. Brentuximab vedotin is not approved in Sézary syndrome.

Mogamulizumab,  marketed  as  Poteligeo,  has  been  approved  by  the  FDA  and  the  EMA  for  the  treatment  of  adult  patients  with  R/R  MF  or  Sézary
syndrome after at least one prior systemic therapy. The response rate to mogamulizumab was 28%, compared to 5% in the control group (vorinostat),
and the median progression-free survival was 7.6 months compared to 3.1 months for the control group. The most common AEs were rash, infusion-
related reactions, fatigue, diarrhea, upper respiratory tract infection and musculoskeletal pain.

Although these new treatments represent progress in the treatment of CTCL, they are still associated with the safety and efficacy limitations observed in their
respective clinical trials. Further, even with these options, the vast majority of these treated patients eventually relapse and overall survival remains poor.

Peripheral T-Cell Lymphoma

PTCL  is  a  diverse  group  of  aggressive  non-Hodgkin’s  lymphomas  that  develop  from  mature  T  cells  and  NK  cells.  PTCL  arises  in  the  lymphoid  tissues
outside of the bone marrow, such as in the lymph nodes, spleen, gastrointestinal tract and skin. The various PTCL types, their frequency as a percentage of all
TCL cases, and prognosis are shown in the following table.

Irrespective of the specific regimen used (single agent chemotherapy or combination chemotherapy including GemOx), patients with R/R PTCL typically
experience a poor outcome, with a median progression-free survival and overall survival of 3.1 months and 5.5 months, respectively.

Multi-agent chemotherapy is the recommended first line treatment for the majority of patients with PTCL. Brentuximab vedotin is approved in combination
with  first  line  chemotherapy  for  patients  with  CD30-positive  PTCL.  For  patients  who  are  eligible,  subsequent  stem  cell  transplantation  is  a  potentially
curative  option  but  it  is  limited  to  a  minority  of  patients.  Despite  these  treatments,  a  high  proportion  of  patients  need  second  line  therapy.  Belinostat
(marketed as Beleodaq), pralatrexate (marketed as Folotyn) and romidepsin (marketed as Istodax) have each been approved by the FDA in this setting, but
efficacy is generally limited. In the respective non-randomized clinical registration trials, the response rate to belinostat, pralatrexate and romidepsin were
each less than 30%, and the median duration of response was approximately 10 months for belinostat and pralatrexate. None of these treatments have been
approved by the EMA.

In fact, despite these approvals, current treatment guidelines recommend participation in a clinical trial as a preferred option for patients with relapsed PTCL
after first line. If clinical trials are not available, a chemotherapy combination of gemcitabine and oxaliplatin, or GemOx, is listed as one of the preferred
treatment combinations. Several studies have been published on the role of GemOx in patients with relapsed lymphoma and it is one of the most widely used
regimens for this patient population in the United States, Europe and Asia.

Phase II Clinical Trial (TELLOMAK)

In May 2019, we initiated a global, open-label, multi-cohort Phase II clinical trial, known as TELLOMAK. This clinical trial is being conducted at more than
10 sites in the United States, pursuant to an IND accepted by the FDA in January 2019, and at 11 sites in France, pursuant to approval by ANSM in February
2019,  and  in  Germany,  Italy  and  the  United  Kingdom.  In  this  trial,  we  are  evaluating  lacutamab  alone  and  in  combination  with  GemOx  in  patients  with
advanced TCL. We expect to recruit up to 250 patients, with lacutamab evaluated as a single agent in approximately 60 patients with Sézary syndrome who
have received at least two prior treatments, including mogamulizumab, as a single agent in approximately 90 patients with MF who have received at least
two prior systemic therapies, and as combination with standard chemotherapy (GemOx) in approximately 100 patients with PTCL who have received at least
one prior treatment. The MF and PTCL arms will be comprised of two cohorts each, testing lacutamab in KIR3DL2 expressing and non-expressing patients.
These cohorts will follow a Simon 2-stage design that will terminate if treatment is considered futile. The following graphic depicts the trial design:

119

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
The primary endpoint of the trial is objective response rate, measured using the 2011 Olsen criteria for CTCL or the Lugano criteria for PTCL, respectively.
Key  secondary  measures  include  incidence  of  treatment-emergent  AEs,  the  effect  of  skin  disease  on  quality  of  life  as  measured  by  the  Skindex29
questionnaire, pruritus as measured by the Visual Analog Scale, progression-free survival and overall survival. The results of the dedicated Sézary syndrome
cohort may support a future BLA submission to the FDA.

In November 2019, Impletio Wirkstoffabfüllung GmbH (formerly known as Rentschler Fill Solutions GmbH), the subcontractor in charge of the fill-and-
finish  manufacturing  operations  of  lacutamab  unilaterally  decided  to  withdraw  the  certificates  of  conformance  of  all  clinical  batches  produced  at  their
facilities,  including  the  lacutamab  batch  used  for  the  TELLOMAK  Phase  II  clinical  trial  assessing  lacutamab  in  multiple  indications.  Impletio
Wirkstoffabfüllung GmbH decided to withdraw the certificates of conformance even though the compliance of its manufacturing site with GMP has been
confirmed by two on-site inspections performed by a local regulator before and after we began to work with them. Impletio Wirkstoffabfüllung GmbH also
filed for bankruptcy.

Since  November  2019,  we  have  been  in  ongoing  discussions  with  US  and  European  national  regulatory  authorities  regarding  GMP  deficiencies  at  our
manufacturing subcontractor site that managed the fill and finish operations of the lacutamab clinical vials for TELLOMAK. As of today:

·

France and the U.K.: We have reactivated the TELLOMAK trial in Sézary syndrome and MF in France and in the U.K., following authorization by the
respective national authorities. Since standard of care options are available to patients with PTCL, we have decided not to enroll further patients in the
trial until a new batch conforming with GMP is available. However, currently enrolled patients from all cohorts can continue treatment in the trial.

120

 
 
 
 
 
 
 
 
·

US, Spain, Germany, and Italy: TELLOMAK remains on partial clinical hold in the U.S., in addition to Spain and Germany, based on feedback from
the  respective  regulatory  authorities.  This  means  that  currently  enrolled  patients  can  continue  treatment  in  the  trial.  However,  no  new  patients  can
enroll in the trial until a new batch conforming with GMP is available. The clinical trial has been suspended in Italy.

There  was  no  safety  issues  related  to  the  trial  medication.  This  is  consistent  with  the  review  conducted  by  the  Independent  Data  Monitoring  Committee
(IDMC), which concluded there were no safety issues related to lacutamab, and the product appeared to be well-tolerated among current patients enrolled in
the trial. We are working on the transfer of the lacutamab fill and finish manufacturing operations to new CMOs. We anticipate that a new clinical batch
conforming  with  GMP  should  be  available  in  the  second  half  of  2020.  We  will  continue  to  work  with  the  U.S.  Food  and  Drug Administration  and  other
European national regulatory agencies to get the trial fully reactivated as. In addition, we are evaluating other options for PTCL and will provide a further
update in due time. We expect first preliminary efficacy data for Sézary and MF cohorts starting in 2021.

Phase I Clinical Trial

In November 2015, we began a Phase I dose-escalating and cohort expansion clinical trial to evaluate lacutamab for the treatment of advanced CTCL. The
trial enrolled 44 patients, including 35 patients with Sézary syndrome. The primary objective of the trial was to evaluate lacutamab safety, and to identify
DLTs and the maximum tolerated dose. Data from this trial were presented at the 2018 meeting of the American Society of Hematology. We reported clinical
activity in the subgroup of 35 Sézary syndrome patients, including an observed overall response rate of 42.9%, median duration of response of 13.8 months,
median  progression-free  survival  of  11.7  months  and  that  approximately  90%  of  patients  experienced  improved  quality  of  life.  The  overall  response  rate
appeared to be higher (53.6%) in the 28 patients with no histologic evidence of large cell transformation. Clinical activity was associated with a substantial
improvement in quality of life as assessed by the Skindex29 and Pruritus Visual Analog Scale scores. Lacutamab was generally well tolerated. The most
common AEs were peripheral edema (29%), asthenia (26%) and fatigue (23%), all of which were grade 1 or 2. Possibly treatment-related, grade 3 or above
adverse  events  were  observed  in  four  patients  (11%)  and  only  three  patients  (9%)  stopped  treatment  as  a  result  of  an  adverse  event.  One  patient  stopped
treatment because of peripheral neuropathy, one patient stopped treatment because of general malaise and one patient stopped treatment because of several
adverse events, including renal injury, respiratory failure, dysphagia and sepsis.

Recent preclinical data presented in June 2019 further support the rationale of evaluating the potential of lacutamab in larger subsets of patients with TCL.
The  findings  demonstrate  that  KIR3DL2  is  expressed  in  multiple  subtypes  of  PTCL  and  that  the  incubation  of  TCL  cell  lines  with  a  combination
chemotherapy regimen consisting of gemcitabine and oxaliplatin, or GemOx, enhanced KIR3DL2 expression. Moreover, we observed that the combination
of lacutamab and GemOx improved anti-tumor activity against a KIR3DL2-positive T-cell line in vitro.

121

 
 
 
 
 
 
 
 
Additionally, we believe this preclinical data supports the potential expansion of the lacutamab development program into Adult T-cell leukemia/lymphoma,
or ATLL, which is mostly prevalent in Asia, particularly in Japan. The data demonstrates that KIR3DL2 expression is mainly associated with the ATLL acute
subtype, a subtype that is the most frequent and associated with the poorest prognosis.

Avdoralimab (IPH5401), an Anti-C5aR Antibody Acting on Immunosuppressive Cells in the Tumor Microenvironment

Overview and Mechanism of Action

Our  most  advanced  antibody  targeting  the  tumor  microenvironment  is  avdoralimab,  which  is  designed  to  bind  to  and  block  the  C5a  receptor,  or  C5aR,  a
receptor  that  is  expressed  on  MDSCs  and  neutrophils.  Part  of  the  innate  immune  system,  these  types  of  cells  promote  tumor  growth  by  secreting
inflammatory and angiogenic factors that promote blood vessel growth, potently suppress T cells and NK cells and hamper the activities of PD-1 checkpoint
inhibitors. C5a, a factor in the complement cascade, is often overexpressed in tumors, where it attracts and activates MDSCs and neutrophils in the tumor
microenvironment, promoting an immunosuppressive environment at the tumor bed. The table below shows the percentage of IO-resistant NSCLC patients
with more than four times higher expression of C5 and C5aR1 than NSCLC patients that have not received prior IO treatment.

The image below depicts the mechanism of action of avdoralimab. Avdoralimab (IPH5401) is designed to bind to C5aR, thereby blocking its ability to bind
to C5a. This blocking allows the CD8+ or CD4 T cells and NK cells, which would otherwise be suppressed by MDSC and neutrophils, to target and kill the
tumor.

122

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Our preclinical studies support development of avdoralimab in combination with PD-1 checkpoint inhibitors or other immunotherapies in cancer.

  Solid Tumors, NSCLC, HCC

In January 2018, we entered into a non-exclusive clinical trial collaboration with AstraZeneca with respect to avdoralimab. As part of this collaboration, we
are conducting a multi-center, open label, dose-escalation and dose-expansion Phase I/II clinical trial (STELLAR-001) to evaluate the safety and efficacy of
avdoralimab  in  combination  with  durvalumab,  an  anti-PD-L1  immune  checkpoint  inhibitor,  as  a  treatment  for  patients  with  solid  tumors,  including  non-
small-cell lung carcinoma, or NSCLC, with secondary resistance to prior immuno-oncology treatment and IO-naïve hepatocellular carcinoma, or HCC. The
trial  is  being  conducted  at  two  sites  in  the  United  States  pursuant  to  an  IND  accepted  by  the  FDA  in  May  2018  and  at  two  sites  in  France  pursuant  to
approval by ANSM. The first patient in this clinical trial was enrolled in September 2018. During the third quarter of 2019, the Company has decided to add
an additional cohort testing avdoralimab in combination with durvalumab in IO-pretreated HCC patients, subject to regulatory approval. We expect to enroll
up to 140 patients in total.

This trial consists of a dose-escalation part and three expansion cohorts. In the dose-escalation part, patients receive avdoralimab) in combination with 1,500
mg of durvalumab every 4 weeks. The first expansion cohort will evaluate the avdoralimab) and durvalumab combination in patients with NSCLC who are
IO-pretreated; the second expansion cohort will evaluate the avdoralimab and durvalumab combination in patients with HCC who are IO-naïve; and the third
expansion  cohort  will  evaluate  avdoralimab  in  combination  with  durvalumab  in  IO-pretreated  HCC  patients.  The  primary  endpoints  of  this  trial  are
assessment  of  DLTs  for  up  to  six  weeks  after  treatment  and  AEs  from  screening  through  up  to  30  days  after  the  last  dose  of  trial  medication.  Secondary
endpoints include objective response rate according to RECIST 1.1, duration of response and progression-free survival. The graphic below depicts the trial
design:

123

 
 
 
 
 
 
 
 
 
 
 
 
 
We reported preliminary safety data from this clinical trial at the 2019 ESMO annual meeting in the second half of 2019. This data evaluated 14 patients
across four dose levels. Of these patients, six had NSCLC, five had HCC, two had urothelial carcinoma, or UCC, and one had renal cell carcinoma, or RCC.

In our STELLAR-001 clinical trial we observed that the combination of avdoralimab and durvalumab was well tolerated, and no DLTs were observed in the
trial. Additionally, no dose relationship was observed regarding safety during the clinical trial. Finally, pharmacodynamic analyses confirmed full saturation
of the C5a receptors at all dose levels and provided the basis for dose selection for the expansion cohorts. Early activity signals were also observed in HCC
and NSCLC patients, including one confirmed partial response in an HCC patient with prior progression after nivolumab and one prolonged stable disease
(40 weeks) in a NSCLC patient with prior progression after nivolumab.

As of August 26, 2019, one patient death due to tumor progression was reported but no treatment-related deaths were observed in this clinical trial. Treatment
was discontinued due to tumor progression in 11 patients and due to a TEAE (pneumonitis) in one patient. Additionally, 84 AEs were reported among the 14
patients treated, of which 11 were grade 3 or 4 AEs and 20 were non-severe, grade 1 or 2 AEs. One SAE, exacerbation of chronic obstructive pulmonary
disease, considered not to be related to avdoralimab) and durvalumab, was reported. Finally, five grade 1 or 2 AEs were reported as relating to avdoralimab
treatment, which included fatigue, white blood cell count decrease, headache and dry mouth. There were no severe TEAEs relating to avdoralimab and no
dose relationship was observed.

We  are  initiating  an  expansion  cohort  to  evaluate  avdoralimab  in  combination  with  durvalumab  in  IO-pretreated  NSCLC  patients  and  another  expansion
cohort to evaluate in combination with durvalumab in IO-naïve HCC patients. Based in part on our preliminary data, we have initiated a third expansion
cohort in IO-pretreated HCC patients in the first half of 2020. Pursuant to our agreement, we and AstraZeneca are sharing the costs of this clinical trial on a
50/50 basis.

Avdoralimab for the Treatment of Inflammation

The complement system consists of a network of more than 50 different plasma and membrane associated proteins. It is a part of the innate immune system
and plays a key role in host defense against pathogens as well as in tissue homeostasis. The anaphylatoxin C5a is formed upon cleavage of C5 during the
process  of  complement  activation.  C5a  is  the  most  potent  chemoattractant  and  induces  recruitment  and  activation  of  different  immune  cells  to  inflamed
tissue,  among  which  are  neutrophils,  eosinophils,  monocytes,  basophils,  and  mast  cells.  In  addition,  release  of  C5a  increases  blood  vessel  permeability,
chemokine  release  from  neutrophils,  and  expression  of  adhesion  molecules  on  endothelial  cells.  All  of  these  processes  facilitate  further  immune  cell
recruitment  into  inflamed  tissue  and  local  inflammation.  Unsuitable  activation  of  the  complement  cascade  and  production  of  C5a  are  associated  with
inflammatory conditions including several types of vasculitis, systemic lupus erythematous, rheumatoid arthritis, ischemia/reperfusion injury, hydradenitis
suppurativa, psoriasis, acne, and urticaria.

IPH5201, an Anti-CD39 Antibody Targeting the Immunosuppressive Adenosine Pathway

We  are  developing  a  CD39-blocking  monoclonal  antibody  known  as  IPH5201.  In  preclinical  models  using  both  primary  human  cells  and  tumor  mouse
models,  we  observed  that  the  blockade  of  CD39  could  stimulate  anti-tumor  immunity  across  a  wide  range  of  tumors  by  preventing  the  production  of
adenosine and by promoting the accumulation of extracellular adenosine triphosphate, or ATP, in the tumor microenvironment. CD39 is a membrane-bound
extracellular enzyme that is expressed on the surface of regulatory T cells, B cells, myeloid cells and endothelial cells, and is upregulated on immune cells in
tumor tissue. CD39 inhibits the immune system by degrading ATP into adenosine monophosphate, or AMP, that is then further degraded into adenosine by
CD73.  Within  the  tumor  microenvironment,  ATP  promotes  immune-cell  mediated  killing  of  cancer  cells,  and  accumulation  of  ATP  is  beneficial  for
enhancing anti-tumor immune responses. However, ATP degradation and adenosine accumulation causes immune suppression and dysregulation of immune
cells,  which  results  in  the  spreading  of  tumors.  By  promoting  the  accumulation  of  immune-stimulating  ATP,  and  preventing  the  production  of  immune-
suppressive adenosine, we believe that the blockade of CD39 may stimulate anti-tumor activity across a wide range of tumors.

This  rationale  is  supported  by  our  preclinical  data  for  IPH5201  in  mouse  tumor  models  and  by  the  analysis  of  anti-tumor  immune  responses  in  tumor-
challenged  CD39  knock-out  mice.  In  this  model,  significant  tumor  responses  were  observed  in  response  to  treatment  with  PD-1  inhibitors  and  ADCC-
inducing antibodies, as well as with immunogenic chemotherapy, compared to responses to these agents in wild-type mice. The following images show the
results  of  human  CD39  knock-in  mouse  tumor  model.  The  four  graphs  on  the  left  show  changes  in  tumor  volume  over  time  depending  on  the  type  of
treatment  group,  which  included  a  control  group  (gray),  an  IPH5201  (mouse  version)  group  (blue),  an  oxaliplatin  group  (orange)  and  an  oxaliplatin  and
IPH5201 combination group (purple). The diagram below outlines survival among these four treatment groups.

125

 
 
 
 
 
 
 
 
 
Other preclinical data showed that, in human tumors, CD39 is strongly upregulated on the tumor infiltrating lymphocytes, or TILS, which could contribute to
immunosuppression.  In  in  vitro  preclinical  models  with  human  immune  cells,  IPH5201  restored  T  cell  proliferation  by  blocking  ATP-degradation  into
adenosine. Additionally, IPH5201 enhanced ATP-mediated dendritic cell activation in preclinical models, resulting in T-cell proliferation.

These data were presented at the AACR 2018 annual meeting and were published in May 2019. In 2019, an IND was successfully submitted for IPH5201. A
Phase I first-in-human, multicenter, open-label, dose-escalation study evaluating IPH5201 in monotherapy and in combination with durvalumab (anti-PD-L1)
with or without oleclumab (anti-CD73) in advanced solid tumors commenced in the first half of 2020 and is being conducted by AstraZeneca. Following the
dosing of the first patient on March 9, 2020 in the IPH5201 Phase I clinical trial, AstraZeneca made a $5 million milestone payment to Innate under the
companies’  October  2018  multi-product  oncology  development  collaboration.  Innate  will  make  a  €2.7  million  milestone  payment  to  Orega  Biotech  SAS
pursuant to Innate’s exclusive licensing agreement. AstraZeneca decided to temporarily pause enrollment of the Phase I clinical trial evaluating IPH5201, an
anti-CD39 blocking monoclonal antibody, in adult patients with advanced solid tumors, due to the COVID-19 pandemic.

IPH5301, an Anti-CD73 Antibody Targeting the Immunosuppressive Adenosine Pathway

We are developing a CD73 blocking antibody for immuno-oncology known as IPH5301. CD73 plays a significant role in promoting immunosuppression
through the pathway degrading ADP into adenosine. CD73 blockade promotes anti-tumor immunity by reducing adenosine accumulation. We have generated
a panel of novel anti-CD73 antibodies and, in the first half of 2018, selected a lead product candidate from this program, IPH5301, due to a combination of
parameters including affinity for CD73, inhibition of CD73 enzymatic activity and its chemistry, manufacturing and control profile. We presented preclinical
data further supporting the rationale of developing IPH5301, including in combination with IPH5201, at the AACR 2018 annual meeting. These data were
also published in May 2019. IPH5301 has been observed to have a differentiated and superior activity compared to benchmark antibodies that are currently in
clinical development.

126

 
 
 
 
 
 
 
 
 
 
IPH5301 is more potent in restoring CD4+ and CD8+ T cell proliferation in an ATP-suppression assay, than the most advanced clinical candidates.

We plan to file an IND for IPH5301 in the first half of 2020.

Additional Preclinical Programs

We have a robust pipeline of additional preclinical product candidates across our three development pillars. Within our preclinical pipeline, four programs are
being developed under an option agreement with AstraZeneca including IPH43, an anti-MICA/B anti-body conjugate, the anti-Siglec-9 anti-body program,
and  two  other  programs  with  undisclosed  targets:  a  multi-specific  NKp46  NKCE  program  and  IPH25,  a  checkpoint  inhibitor.  Another  NKCE  program,
IPH61, is being developed in collaboration with Sanofi.

IPH43: Anti-MICA/B Antibody and Tumor Targeting Antibody Program

We  are  developing  IPH43  as  an  antibody-drug  conjugate  targeting  MICA/B  for  the  treatment  of  oncology  indications.  MICA/B  molecules  bind  to  the
NKG2D activating receptor and are specifically expressed on several highly prevalent solid tumors types including in the breast, colon and lung. We believe
an antibody that kills MICA/B-expressing tumor cells could potentially treat these cancers by eliminating tumor cells. Because MICA/B molecules are highly
polymorphic and therefore frequently subject to genetic variation, we have generated a series of high affinity antibodies recognizing equivalently the most
frequent genetic variants of MICA/B. We chose to target MICA/B using an ADC format because it allows the elimination of tumor cells in the condition in
which the tumor is not infiltrated by immune cells, known as an immune desert. This program is in preclinical development.

Anti-Siglec-9 – Checkpoint Inhibitor Program

We are exploring the possibility of developing an antibody designed to reduce the effects of the Siglec-9 receptor for the treatment of cancer. Siglec-9 is an
inhibitory  checkpoint  that  is  expressed  on  a  broad  range  of  immune  cells,  including  NK  cells  and  myeloid  cells  such  as  dendritic  cells,  monocytes  and
neutrophils. Siglec-9 can interact with sialic acids expressed by tumors, leading to a reduced immune cell function that allows tumors to proliferate. In our
preclinical  studies,  we  observed  that  antibodies  designed  to  block  Siglec-9’s  interaction  with  its  ligands  enhanced  NK  cell  cytotoxicity.  We  have  also
observed  in  our  preclinical  studies  that  Siglec-9  is  highly  expressed  on  monocytes  and  dendritic  cells  and  upregulated  on  T  cells  in  cancer  patients,
suggesting a potential additional role as an inhibitory checkpoint agent. This program is in preclinical development.

NKp46 NK Cell Engagers

Multispecific  monoclonal  antibodies,  or  multispecifics,  are  antibody-derived  formats  that  can  simultaneously  bind  to  two  or  more  different  types  of
molecules. A number of studies of bispecific antibodies are currently underway, such as those assessing the safety and efficacy of bispecific T cell engagers,
such as BiTEs, which engage T cells via the antigen receptor on one-side of the bispecific T cell engager, and a tumor antigen on the other side of the BiTE.
These  molecules  have  demonstrated  the  ability  to  reduce  or  slow  the  growth  of  tumors  in  cancer  patients,  but  also  carry  a  significant  toxicity  risk.  This
toxicity risk occurs by engaging all T cells, irrespective of their specificity and development status, potentially leading to an overt production of cytokines by
these  T  cells,  referred  to  as  a  cytokine  storm.  In  parallel,  bispecific  killer  cell  engagers,  or  BiKEs,  that  engage  CD16  receptors  found  on  NK  cells,  and
trispecific killer cell engagers, or TriKEs, that engage CD16 receptors and contain IL-15, a cytokine that promotes NK cell activation and survival, have also
been  developed  to  target  antigens  expressed  on  solid  tumors.  BiKEs  and  TriKEs  can  be  effective  both  in  vitro  and  in  vivo  preclinical  models.  These
multifunctional molecules that engage NK cells could reduce the risks associated with toxicity, as NK cell counts only represent approximately 10% of T cell
counts, thereby potentially limiting the likelihood of inducing a cytokine storm. However, it remains unclear whether these multifunctional CD16 engager
antibodies can activate NK cells in solid tumors since they often express low levels of CD16.

We have developed trifunctional NKCEs to co-engage NKp46 and CD16 on NK cells together with a tumor antigen. In our preclinical studies, we observed
that  NKp46  NKCEs  have  stronger  anti-tumor  activity  as  compared  to  preclinical  findings  from  other  approved  anti-tumor  therapeutic  antibodies,  such  as
rituximab,  Fc-enhanced  obinutuzumab  and  cetuximab.  Additionally,  preclinical  results  indicate  that  trifunctional  NKCEs  promoting  NKp46  and  CD16
receptors  simultaneously  with  the  same  molecule  are  more  potent  than  a  mixture  of  bispecific  reagents  activating  NKP46  and  CD16  separately,  and  can
efficiently  promote  NK  cell  mediated  tumor  cell  lysis  without  inducing  potentially  toxic  off-target  effects.  We  believe  these  results  support  the  clinical
development of NKCEs for cancer immunotherapy, as a complement to existing immuno-oncology approaches. The following images depict the mechanism
of action of these multifunctional NK cell engagers and our preclinical results.

128

 
 
 
 
 
 
 
IPH61 is an NKp46 NKCE developed as part of our research collaboration and licensing agreement with Sanofi for the generation and evaluation of up to
two  NKp46  NKCEs,  using  Sanofi’s  technology  and  tumor  targets  and  our  NK  cell  engager  technology.  Under  the  terms  of  the  agreement,  Sanofi  is
responsible  for  the  development,  manufacturing  and  commercialization  of  products  resulting  from  the  research  collaboration.  We  are  eligible  to  receive
payments of up to €400.0 million primarily upon the achievement of development and commercial milestone as well as royalties ranging from a mid to high
single-digit percentage on net sales.

IPH25 - Checkpoint Inhibitor Program

We  are  conducting  preclinical  studies  to  explore  the  possibility  of  developing  an  antibody  designed  to  block  an  undisclosed  receptor  for  the  treatment  of
cancer. The target for IPH25 is an inhibitory checkpoint that is expressed on a broad range of immune cells, including NK cells, CD8+ T cells, B cells and
mononuclear myeloid cells such as dendritic cells and monocytes. The target’s receptor has been observed on various tumor types and on tumor-infiltrating
immune cells such as tumor-promoting M2 macrophages and it is mostly associated with poor disease outcome. In preclinical models, blocking antibodies
directed  against  the  IPH25  target  reversed  immune  suppression,  promoted  an  antitumor  immune  response  and  enhanced  the  potency  of  other  cancer
therapies.

Competition

The  biotechnology  and  pharmaceutical  industry,  and  notably  the  cancer  field,  is  characterized  by  rapidly  advancing  technologies,  products  protected  by
intellectual property rights and intense competition and is subject to significant and rapid changes as researchers learn more about diseases and develop new
technologies  and  treatments.  While  we  believe  that  our  technology,  knowledge,  experience,  collaborations  and  scientific  resources  provide  us  with
competitive  advantages,  we  face  potential  competition  from  many  different  sources,  including  major  pharmaceutical,  specialty  pharmaceutical  and
biotechnology  companies,  academic  institutions  and  governmental  agencies  and  public  and  private  research  institutions.  Any  approved  product  that  we
commercialize will compete with existing therapies and new therapies that may become available in the future.

There are a large number of companies developing or marketing treatments for cancer, including many major pharmaceutical and biotechnology companies.
Many  of  our  competitors  have  significantly  greater  experience,  personnel  and  resources  as  it  relates  to  research,  drug  development,  manufacturing  and
marketing.  In  particular,  large  pharmaceutical  laboratories  have  substantially  more  experience  than  we  do  in  conducting  clinical  trials  and  obtaining
regulatory authorizations. Mergers and acquisitions in the pharmaceutical, biotechnology and diagnostic 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  are  also  likely  to  compete  with  us  to  recruit  and  retain  top
qualified  scientific  and  management  personnel,  acquire  rights  for  promising  product  candidates  and  technologies,  establish  clinical  trial  sites  and  patient
registration for clinical trials, acquire technologies complementary to, or necessary for, our programs and enter into collaborations with potential partners
who have access to innovative technologies.

129

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are more effective, have a better
safety profile, are more convenient, have a broader label, have more robust intellectual property protection or are less expensive than any products that we
may develop. Our competitors also may obtain regulatory approval for their products more rapidly than we may obtain approval for ours, which could result
in  our  competitors  establishing  a  strong  market  position  before  we  are  able  to  enter  the  market.  In  addition,  our  competitors  could  be  more  efficient  in
manufacturing or more effective in marketing their own products than we or our partners may be in the future.

With respect to our lead product candidate, monalizumab, a novel dual-targeting checkpoint inhibitor, there are several pharmaceutical companies marketing
and  developing  treatments  for  either  SCCHN  or  MSS-CRC.  For  SCCHN,  Erbitux  (cetuximab),  marketed  by  Eli  Lilly,  and  checkpoint  inhibitors  Opdivo
(nivolumab) and Keytruda (pembrolizumab), marketed by Bristol-Myers Squibb and Merck, respectively, have all been approved in the second line setting.
For CRC, Stivarga (regorafenib), marketed by Bayer, and Lonsurf (trifluridine/tipiracil), marketed by Taiho Oncology, are both approved in the third line or
later setting.

With respect to Lumoxiti, our marketed product for the treatment of HCL, there is currently no established standard of care and very few treatment options
available  in  the  third  line  and  later  setting.  The  National  Comprehensive  Cancer  Network,  or  NCCN,  guidelines  for  HCL,  updated  in  January  2019,
recommend that patients who are third line or later in treatment be considered for Lumoxiti as well as participation in clinical trials of vemurafenib, with or
without rituximab, or ibrutinib. Vemurafenib, rituximab and ibrutinib have not been approved by the FDA for the treatment of HCL.

With respect to lacutamab, our monoclonal antibody product candidate targeting KIR3DL2, we are aware of several pharmaceutical companies marketing
and  developing  products  for  the  treatment  of  patients  with  CTCL,  including  MF  and  Sézary  syndrome,  and  PTCL.  Two  new  drugs  have  been  recently
approved  by  the  FDA  for  CTCL:  Adcetris  (brentuximab  vedotin),  marketed  by  Seattle  Genetics  and  approved  in  combination  with  chemotherapy  for
treatment of patients with primary cutaneous anaplastic large cell lymphoma (pcALCL) or CD30-expressing MF who have received prior systemic therapy,
and Poteligeo (mogamulizumab), marketed by Kyowa Kirin and approved for the treatment of adult patients with R/R MF or Sézary syndrome after at least
one prior systemic therapy. Zolinza (vorinostat) is the only drug approved by the FDA for CTCL patients after two prior failures. In the second line setting of
PTCL, Beleodaq (belinostat), Folotyn (pralatrexate) and Istodax (romidepsin) have all been approved by the FDA; however, none of these treatments have
been approved by the EMA.

130

 
 
 
 
 
 
 
 
There  are  also  several  pharmaceutical  and  biotechnology  companies  that  are  focused  on  the  tumor  microenvironment,  including  the  complement  and  the
adenosine pathways. The C5a and C5aR pathways have attracted efforts mainly in inflammation, but we are aware of some companies targeting C5a or C5aR
in the oncology settings as well, such as MorphoSys AG and InflaRx N.V. Many companies are active in the adenosine pathway, targeting CD73, CD39 or
the adenosine receptors. For example, Bristol-Myers Squibb and AstraZeneca each have anti-CD73 product candidates in clinical development, and several
other biotechnology companies are active in the adenosine pathway area, including Tizona Therapeutics, Inc., AbbVie Inc., Corvus Pharmaceuticals, Inc.,
Arcus Biosciences, Inc. and Surface Oncology, Inc.

NK cells have been increasingly researched and we are aware of many companies addressing NK cells through different approaches such as cell therapies
(Fate Therapeutics, Inc., NantKwest, Inc.) and multispecifics (Affimed N.V., Dragonfly Therapeutics, Inc.)

The term of individual patents depends upon the legal term of patents in the countries in which they are obtained. In most countries, including the United
States,  the  patent  term  is  20  years  from  the  earliest  claimed  filing  date  of  a  non-provisional  patent  application  or  its  foreign  equivalent  in  the  applicable
country. In the United States, a patent’s term may, in certain cases, be lengthened by patent term adjustment, which compensates a patentee for administrative
delays by the USPTO in examining and granting a patent, or may be shortened if a patent is terminally disclaimed over a commonly owned patent or a patent
naming a common inventor and having an earlier expiration date. In the United States, a patent may also be eligible for limited patent term extension under
the Drug Price Competition and Patent Term Restoration Act of 1984, or Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent
extension term of up to five years as compensation for patent term lost during the FDA regulatory review process. A patent term extension cannot extend the
remaining term of a patent beyond a total of 14 years from the date of product approval, only one patent applicable to each regulatory review period may be
extended and only those claims covering the approved drug, a method for using it, or a method for manufacturing it may be extended.

Trademarks

We  own  the  mark  INNATE  PHARMA  in  the  United  States, Australia  and  Europe  (EU  community  trademark),  and  INNATE  in  Europe  (EU  community
trademark)  as  well  as  the  mark  LUMOXITI  and  a  figurative  mark  associated  with  the  Lumoxiti  product  in  the  United  States,  Europe  (EU  community
trademark) and other countries throughout the world.

Regulation

Research and development work, preclinical tests, clinical studies, facilities, and the manufacture and sale of our products are and will continue to be subject
to  the  complex  legislative  and  regulatory  provisions  implemented  by  the  various  public  authorities  in  Europe,  the  United  States  and  other  countries.  The
EMA, FDA and the various national regulatory authorities impose considerable constraints on the development, manufacture and sale of products that we
develop  and  clinical  trials  we  conduct.  In  case  of  non-compliance  with  these  regulations,  the  regulatory  authorities  may  impose  fines,  seize  or  remove
products  from  the  market  or  even  partially  or  totally  suspend  their  production.  They  may  also  revoke  previously  granted  marketing  authorizations,  reject
authorization applications. These regulatory constraints are important in considering whether an active ingredient can ultimately become a drug, as well as
for recognizing the time and investments necessary for such development.

Although there are differences from one country to another, the development of therapeutic products for human use is subject to similar procedures and must
comply with the same types of regulations in all ICH countries (countries part of the International Council for Harmonisation of Technical Requirements for
Registration of Pharmaceuticals for Human Use). In order to obtain marketing authorization for a product, proof of its efficacy and safety should be provided
by  the  applicant,  along  with  detailed  information  on  its  composition  and  manufacturing  process.  This  entails  significant  pharmaceutical  and  preclinical
developments, clinical trials and laboratory tests. The development of a new drug from fundamental research to marketing comprises five steps: (i) research,
(ii) preclinical trials, (iii) clinical trials in humans, (iv) marketing authorization and (v) marketing.

133

 
 
 
 
 
 
 
 
 
 
Preclinical studies

Preclinical  studies  include  laboratory  evaluation  of  the  purity  and  stability  of  the  manufactured  substance  or  active  pharmaceutical  ingredient  and  the
formulated  product,  as  well  as  in  vitro  and  animal  studies  to  assess  the  safety  and  activity  of  the  product  candidate  for  initial  testing  in  humans  and  to
establish  a  rationale  for  therapeutic  use.  The  conduct  of  preclinical  studies  is  subject  to  federal  regulations  and  requirements,  including  Good  Laboratory
Practices  (GLP)  regulations.  The  results  of  the  preclinical  tests,  together  with  manufacturing  information,  analytical  data,  any  available  clinical  data  or
literature and plans for clinical studies, among other things, are submitted to the applicable regulatory agency in connection with the application to begin
human testing. Some long-term preclinical testing, such as animal tests of reproductive adverse events and carcinogenicity, and long-term toxicity studies,
may continue after submission of the application.

Regulation of clinical trials

In humans, clinical trials are usually carried out in three phases that are generally sequential, but under unique circumstances phases of trials can overlap or
even be skipped, following a specific review and determination by regulatory agencies. Clinical trials are sometimes necessary after marketing authorization
to  explain  certain  side-effects,  investigate  a  specific  pharmacological  effect,  obtain  more  accurate  or  additional  data.  Additional  trials  are  also  commonly
conducted to explore new indications. Regulatory authorization is needed to carry out clinical trials. The regulatory authorities may block, suspend or require
significant modifications to the clinical study protocols submitted by companies seeking to test products.

Clinical trial authorization in the European Union

The current regulation relating to clinical trials is governed by European Directive 2001/20/EC of April 4, 2001 on clinical trials, which has been transposed
into national legislation by all European Union Member States.

The  2001  Directive  cited  above  has  been  revised  and  replaced  by  the  Clinical  Trials  Regulation  EU  No.  536/2014  of  April  16,  2014,  which  aims  at
harmonizing and streamlining the clinical trials authorization process. The Clinical Trial Regulation EU No. 536/2014 of April 16, 2014 entered into force on
June 16, 2014. However, the regulation will not become applicable until the publicly available EU database and EU portal are fully functional and have been
confirmed  through  an  independent  audit.  The  new  regulation  will  become  applicable  six  months  after  the  European  Commission  publishes  notice  of  this
confirmation. Due to technical difficulties with the development of the IT systems, the portal’s go-live date had to be postponed and therefore the Clinical
Trials  Regulation  are  expected  to  come  into  application  in  the  course  of  2022.  It  will  apply  to  interventional  clinical  trials  on  medicinal  products  and  to
clinical trials authorized under the current 2001 Directive still ongoing three years after the Clinical Trial Regulation has come into operation.

134

 
 
 
 
 
 
 
 
 
 
 
The Clinical Trial Regulation will allow better consistency throughout EU Member States:

·

·

Single  submission  of  the  clinical  trial  application  dossier  through  the  EU  Portal  (Article  5)  including  a  common  part  assessed  jointly  by  all
participating  EU  Member  States,  and  a  national  part  covering  the  ethical  and  operational  aspects  of  the  trial  assessed  by  each  EU  Member  State
independently.

A clinical trial authorization will be issued in the form of a single decision by each EU Member State concerned (Article 4).

The Clinical Trials Regulation will apply in the Member States without the requirement for separate implementing legislation by each Member State, but
some of the existing laws of the Member States applicable at a national level will continue to apply.

This new regulation will also increase transparency of authorized clinical trials in the European Union: the European Union database will serve as the source
of  public  information,  without  prejudice  of  personal  data  protection,  commercially  confidential  information  protection,  and  protection  of  confidential
communication between Member State and trial supervision between Member States. Public information will include clinical trial authorization information,
protocol data, and a summary of the results 12 months after the end of the trial (or six months in case of pediatric clinical trials).

Clinical trial authorization in the United States

In the United States, an Investigational New Drug application, or IND, must be submitted to the FDA and accepted before clinical trials can start on humans.
An IND is an exemption from the Federal Food, Drug, and Cosmetic Act, or FDCA, that allows an unapproved product candidate to be shipped in interstate
commerce for use in an investigational clinical trial and a request for FDA authorization to administer an investigational product to humans. This application
contains  early  research  data  as  well  as  the  pharmaceutical  dossier,  preclinical  and  clinical  data  (if  any)  and  includes  the  clinical  protocol.  If  there  is  no
objection from the FDA, the IND application becomes valid 30 days after it is received by the FDA. This waiting period is designed to allow the FDA to
review the IND to determine whether human research subjects will be exposed to unreasonable health risks. At any time during or subsequent to this 30-day
period,  the  FDA  may  request  the  suspension  of  clinical  trials,  whether  such  trials  are  planned  or  in  progress,  and  request  additional  information.  This
temporary suspension continues until the FDA receives the information it has requested.

In addition to the foregoing IND requirements, an independent institutional review board, or IRB, representing each institution participating in the clinical
trial  must  review  and  approve  the  plan  for  any  clinical  trial  before  it  commences  at  that  institution,  and  the  IRB  must  conduct  continuing  review  and
reapprove the study at least annually. The IRB must review and approve, among other things, the study protocol and informed consent information to be
provided to study subjects. An IRB must operate in compliance with FDA regulations. An IRB can suspend or terminate approval of a clinical trial at its
institution, or an institution it represents, if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the product candidate has
been associated with unexpected serious harm to patients.

135

 
 
 
 
 
 
 
 
 
 
 
 
The FDA’s primary objectives in reviewing an IND are to assure the safety and rights of patients and to help assure that the quality of the investigation will
be  adequate  to  permit  an  evaluation  of  the  biological  product’s  safety,  purity  and  potency.  The  decision  to  terminate  development  of  an  investigational
biological product may be made by either a health authority body such as the FDA, an IRB or ethics committee, or by us for various reasons. Additionally,
some trials are overseen by an independent group of qualified experts organized by the 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 check points based on access that only the group maintains to
available data from the study. Suspension or termination of development during any phase of clinical trials can occur if it is determined that the participants
or patients are being exposed to an unacceptable health risk. Other reasons for suspension or termination may be made by us based on evolving business
objectives and/or competitive climate.

Good clinical practices (GCP)

In most countries, clinical trials must comply with the cGCP standards as defined by the International Council for Harmonization of Technical Requirements
for  Registration  of  Pharmaceuticals  for  Human  Use,  or  ICH.  Directive  2005/28/EC  dated  April  8,  2005  adopted  the  cGCP  principles  in  the  context  of
strengthening the regulatory structure specified by Directive 2001/20/EC. The competent authority designated in each Member Country to authorize clinical
trials must take into consideration, among other factors, the scientific value of the study, the safety of the participants and the possible responsibility of the
clinical site.

Conducting clinical trials

Clinical trials must be carried out in compliance with complex regulations throughout the various phases of the process, based on the principle of informed
consent by the patient to whom the products will be administered.

Clinical trial phases

Clinical trials may be conducted in the United States, in Europe or in other parts of the world as long as such trials have been approved by health authorities
and ethics committees in each country where the trial is conducted. There are three well-established and internationally-recognized clinical phases: Phase I, II
and III. This classification is used by the FDA and the EMA, as well as other regulatory agencies. Each of these clinical phases is described below.

·

Phase  I:  The  product  candidate  is  initially  introduced  into  healthy  human  subjects  and  tested  for  safety,  dosage  tolerance,  absorption,  metabolism,
distribution and excretion. In the case of some products for severe or life-threatening diseases, such as cancer, especially when the product may be too
inherently toxic to ethically administer to healthy volunteers, the initial human testing is often conducted in patients. Sponsors sometimes designate
their Phase I trials as Phase Ia or Phase Ib. Phase Ib trials are typically aimed at confirming dosing, pharmacokinetics and safety in larger number of
patients.  Some  Phase  Ib  studies  evaluate  biomarkers  or  surrogate  markers  that  may  be  associated  with  efficacy  in  patients  with  specific  types  of
diseases.

136

 
 
 
 
 
 
 
 
 
 
 
 
·

·

Phase II: This phase involves clinical trials in a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate
the efficacy of the product for specific targeted diseases and to determine dosage tolerance and appropriate dosage.

Phase III: Clinical trials are undertaken to further evaluate dosage, clinical efficacy and safety in an expanded patient population at geographically
dispersed  clinical  study  sites.  These  clinical  trials,  generally  comparative,  are  intended  to  establish  the  overall  risk-benefit  ratio  of  the  product
candidate and provide, if appropriate, an adequate basis for product labeling.

Post-approval trials, sometimes referred to as Phase IV studies, 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 certain instances, the applicable regulator may mandate the performance
of Phase IV clinical trials as a condition of approval.

In specific situations, certain phases of development can be merged or even skipped when clear signs of efficacy emerge in the early phases of development
and  the  product  candidate  is  designed  for  patients  with  major  unmet  medical  needs.  However,  these  deviations  from  the  standard  pattern  of  development
must be discussed and approved by health authorities. Given the high unmet medical need for certain cancer patients, deviations from the typical phases of
development are frequent in oncology and in particular, in the field of immunotherapy.

Disclosure of clinical trial information

Sponsors  of  clinical  trials  of  FDA-regulated  drugs  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  disclose  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. Competitors may use this
publicly available information to gain knowledge regarding the progress of development programs.

Regulations concerning marketing authorizations

In order to be marketed, a drug product must have regulatory authorization (known as approval of a New Drug Application, or NDA, or a Biologics License
Application, or BLA, in the United States and a Marketing Authorization, or MA, in the European Union). The competent authorities are the FDA in the
United States and the EMA in Europe. Companies apply for an NDA/BLA or an MA based on quality, safety and efficacy. In Europe, the United States and
Japan, the dossier is a standard dossier referred to as a CTD, or Common Technical Document. The file relating to the NDA/MA describes the manufacturing
of the active substance, the manufacturing of the final product and the clinical and non-clinical studies.

United States review and approval process for biological products

In the United States, the FDA approves complex biological products under the Public Health Service Act, or PHSA. In order to obtain approval to market a
biological product in the United States, a marketing application must be submitted to the FDA that provides data establishing the safety, purity and potency
of the proposed biological product for its intended indication. The application includes all relevant data available from pertinent preclinical and clinical trials,
including negative or ambiguous results as well as positive findings, together with detailed information relating to the product’s chemistry, manufacturing,
controls and proposed labeling, among other things. Data can come from company-sponsored clinical trials intended to test the safety and effectiveness 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, purity and potency of the biological product to the satisfaction of the FDA.

137

 
 
 
 
 
 
 
 
 
 
 
 
 
 
The BLA is thus a vehicle through which applicants formally propose that the FDA approve a new product for marketing and sale in the United States for
one or more indications. Every new product candidate must be the subject of an approved BLA before it may be commercialized in the United States. Under
federal law, the submission of most BLAs is subject to an application user fee and the sponsor of an approved BLA is also subject to annual program user
fees.  These  fees  are  typically  increased  annually.  Certain  exceptions  and  waivers  are  available  for  some  of  these  fees,  such  as  an  exception  from  the
application  fee  for  products  with  orphan  designation  and  a  waiver  for  certain  small  businesses,  an  exception  from  the  establishment  fee  when  the
establishment does not engage in manufacturing the product during a particular fiscal year, and an exception from the product fee for a product that is the
same as another product approved under an abbreviated pathway.

Following submission of a BLA, the FDA conducts a preliminary review of the application generally within 60 calendar days of its receipt and strives to
inform  the  sponsor  by  the  74th  day  after  the  FDA’s  receipt  of  the  submission  to  determine  whether  the  application  is  sufficiently  complete  to  permit
substantive  review.  The  FDA  may  request  additional  information  rather  than  accept  the  application  for  filing.  In  this  event,  the  application  must  be
resubmitted with the additional information. The resubmitted application is also subject to review before the FDA accepts it for filing. Once the submission is
accepted  for  filing,  the  FDA  begins  an  in-depth  substantive  review.  The  FDA  has  agreed  to  specified  performance  goals  in  the  review  process  of  BLAs.
Under that agreement, 90% of applications seeking approval of New Molecular Entities, or NMEs, are meant to be reviewed within ten months from the date
on  which  FDA  accepts  the  application  for  filing.,  and  90%  of  applications  for  NMEs  that  have  been  designated  for  “priority  review”  are  meant  to  be
reviewed within six months of the filing date. For applications seeking approval of products that are not NMEs, the ten-month and six-month review periods
run from the date that FDA receives the application. The review process and the Prescription Drug User Fee Act goal date may be extended by the FDA for
three additional months to consider new information or clarification provided by the applicant to address an outstanding deficiency identified by the FDA
following the original submission.

Before approving an application, the FDA typically will inspect the facility or facilities where the product is or will be manufactured. These pre-approval
inspections  may  cover  all  facilities  associated  with  a  BLA  submission,  including  component  manufacturing,  finished  product  manufacturing,  and  control
testing  laboratories. The  FDA  will  not  approve  an  application  unless  it  determines  that  the  manufacturing  processes  and  facilities  are  in  compliance  with
cGMP requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving a BLA, the
FDA  will  typically  inspect  one  or  more  clinical  sites  to  assure  compliance  with  GCP.  In  addition,  as  a  condition  of  approval,  the  FDA  may  require  an
applicant to develop a Risk Evaluation and Mitigation Strategy, or REMS. REMS use risk minimization strategies beyond the professional labeling to ensure
that the benefits of the product outweigh the potential risks. To determine whether a REMS is needed, the FDA will consider the size of the population likely
to  use  the  product,  seriousness  of  the  disease,  expected  benefit  of  the  product,  expected  duration  of  treatment,  seriousness  of  known  or  potential  adverse
events, and whether the product is a new molecular entity.

138

 
 
 
 
 
 
 
The FDA may refer an application for a novel product to an advisory committee or explain why such referral was not made. Typically, an advisory committee
is a panel of independent experts, including clinicians and other scientific experts, that reviews, evaluates and provides 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.

On the basis of the FDA’s evaluation of the application and accompanying information, including the results of the inspection of the manufacturing facilities,
the  FDA  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 generally outlines the deficiencies in the submission and may require substantial
additional  testing  or  information  in  order  for  the  FDA  to  reconsider  the  application.  If  and  when  those  deficiencies  have  been  addressed  to  the  FDA’s
satisfaction in a resubmission of the BLA, the FDA will issue an approval letter. The FDA has committed to reviewing such resubmissions in two or six
months  depending  on  the  type  of  information  included.  Even  with  submission  of  this  additional  information,  the  FDA  ultimately  may  decide  that  the
application does not satisfy the regulatory criteria for approval.

If  the  FDA  approves  a  product,  it  may  limit  the  approved  indications  for  use  for  the  product,  require  that  contraindications,  warnings  or  precautions  be
included in the product labeling, require that post-approval studies, including Phase 4 clinical trials, be conducted to further assess the product’s safety after
approval,  require  testing  and  surveillance  programs  to  monitor  the  product  after  commercialization,  or  impose  other  conditions,  including  distribution
restrictions  or  other  risk  management  mechanisms,  including  Risk  Evaluation  and  Mitigation  Strategy  (REMS),  which  can  materially  affect  the  potential
market  and  profitability  of  the  product.  The  FDA  may  prevent  or  limit  further  marketing  of  a  product  based  on  the  results  of  post-marketing  studies  or
surveillance programs.

Registration procedures in Europe

To  access  the  European  markets  through  community  procedures,  drug  products  must  be  submitted  through  the  Centralized  Procedure,  the  Mutual
Recognition  Procedure  or  the  Decentralized  Procedure.  The  process  for  doing  this  depends,  among  other  things,  on  the  nature  of  the  medicinal  product.
Regulation (EC) No 726/2004 of the European Parliament and of the Council of March 31, 2004 provides for the Centralized Procedure. The Centralized
Procedure results in a single marketing authorization (MA), granted by the European Commission that is valid across the European Economic Area or EEA
(i.e., the European Union as well as Iceland, Liechtenstein and Norway). The Centralized Procedure is compulsory for human drugs that are: (i) derived from
biotechnology  processes,  (ii)  contain  a  new  active  substance  indicated  for  the  treatment  of  certain  diseases,  such  as  cancer,  HIV/AIDS,  diabetes,
neurodegenerative diseases, autoimmune and other immune dysfunctions and viral diseases, (iii) officially designated orphan medicines and (iv) advanced-
therapy medicines, such as gene therapy, somatic cell therapy or tissue-engineered medicines.

139

 
 
 
 
 
 
 
 
 
Under Article 3 of the Regulation (EC) No 726/2004, the Centralized Procedure is optional for any medicinal product not appearing in the Annex if: (1) the
medicinal product contains a new active substance which, on the date of entry into force of this Regulation, was not authorized in the EU; or (2) the applicant
shows that the medicinal product constitutes a significant therapeutic, scientific or technical innovation or that the granting of authorization in accordance
with this Regulation is in the interests of patients or animal health at EU level.

Under  the  Centralized  Procedure  in  the  European  Union,  the  European  Medicines  Agency,  or  EMA,  shall  ensure  that  the  opinion  of  the  Committee  for
Medicinal Products for Human Use, or CHMP, is given within 210 days (Article 6.3). This excludes so-called clock stops, during which additional written or
oral  information  is  to  be  provided  by  the  applicant  in  response  to  questions  asked  by  the  Committee  for  Medicinal  Products  for  Human  Use,  or  CHMP
(Article  7).  At  the  end  of  the  review  period,  the  Committee  for  Medicinal  Products  for  Human  Use  (CHMP)  of  the  EMA  provides  its  opinion  through  a
scientific assessment report to the European Commission. The Commission may then adopt a final decision to grant an MA. Once granted, the MA is valid
across all EEA countries for an initial period of five years. Since 2008, as a consequence of a European directive, a marketing authorization is now renewed
only once, five years after the initial registration. The marketing authorization shall be then valid for an unlimited period, unless the Commission decides, on
justified grounds, relating to pharmacovigilance, to proceed with one additional five-year renewal.

When an application is submitted for a MA in respect of medicinal products for human use which are of major interest from the point of view of public
health and in particular from the viewpoint of therapeutic innovation, the applicant may request an accelerated assessment procedure. The request shall be
duly substantiated. If the CHMP accepts the request, the time-limit laid down in Article 6(3), first subparagraph, shall be reduced to 150 days (Article 14(9)).

National MAs, issued by the competent authorities of the member states of the EEA, are also available; however these only cover their respective territory.
National  MAs  may  be  applied  for  through  the  Mutual  Recognition  Procedure  or  Decentralized  Procedure  in  order  that  multiple  competent  authorities  in
different member states of the EEA may each issue a national MA in their territory for the same product on the back of the same application. National MAs
are only available for products not falling within the mandatory scope of the Centralized Procedure.

It is possible for a drug to be withdrawn from the market, upon the request of the health authorities, if a serious problem arises, in particular a safety-related
problem. The marketing authorization is then cancelled. There can be various reasons for the withdrawal of drugs from the market, with the main reasons
being public health, major undesirable side effects and non-compliance with manufacturing rules.

140

 
 
 
 
 
 
 
 
 
Non-standard registration procedures

Aside from the standard procedures of granting a BLA or a European MA, as described above, there are non-standard registration procedures that allow a
shorter time-to-market for new medicines.

The following expedited approval programs are in place in the United States:

·

·

·

·

The Accelerated Approval is a program that is intended to make promising products for life threatening diseases available on the market on the basis
of  preliminary  evidence  prior  to  formal  demonstration  of  patient  benefit.  The  FDA  evaluation  is  performed  on  the  basis  of  a  surrogate  marker  (a
measurement intended to substitute for the clinical measurement of interest) that is considered likely to predict patient benefit. A result of substitution
or marker (“surrogate endpoint”) is a result of laboratory or physical sign that is not in itself a direct measure of the patient’s feelings, its functions or
survival, but which allows to anticipate a therapeutic benefit. The approval that is granted may be considered as a provisional approval with a written
commitment  to  complete  clinical  studies  that  formally  demonstrate  patient  benefit.  This  procedure  is  equivalent  to  the  “conditional  approval”  in
Europe.

The  Priority  Review  is  given  to  drugs  that  offer  major  advances  in  treatment,  or  provide  a  treatment  where  no  adequate  therapy  exists.  A  Priority
Review  means  that  the  time  it  takes  FDA  to  review  a  new  drug  application  is  reduced  to  six  months  rather  than  10  months.  This  procedure  is
equivalent to the “accelerated approval” in Europe.

The  Fast  Track  Program  refers  to  a  process  for  interacting  with  FDA  to  facilitate  the  development  and  expedite  the  review  of  new  drugs  that  are
intended  to  treat  serious  or  life-threatening  conditions  and  that  demonstrate  the  potential  to  address  unmet  medical  needs.  The  advantages  of  this
process include scheduled meetings to seek FDA input into clinical development plans and to collect appropriate data that will be needed to support
approval. Fast Track designation does not necessarily lead to a Priority Review or Accelerated Approval.

The  Breakthrough  Therapy  Designation  is  aimed  at  accelerating  the  development  and  examination  of  drugs  which  are  intended  to  treat  serious
illnesses and where the preliminary clinical evidence indicates that the drug may exhibit a substantial improvement over the available therapies with
regard to clinically significant criterion (criteria).

A drug which is given the designation “Breakthrough Therapy” can benefit from the following:

·

·

·

All of the features of the designation “Fast Track”;

Intensive support on a program for the development of effective drugs, from Phase I onwards; and

Organizational commitment involving “FDA senior managers.”

141

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If research or additional studies show that a product presents a risk when it is marketed, the FDA may require its immediate withdrawal. In addition, FDA
may withdraw approval for placing on the market for other reasons, especially if the studies after approval are not made with due care.

In Europe, non-standard registration procedures under the Centralized Procedures are as follows:

·

·

·

Conditional approval: valid only one year instead of five. It is granted only if the benefit / risk ratio is positive, that is if the product responds to unmet
medical needs, and if the benefits to public health outweigh the risks associated with uncertainty because of an incomplete evaluation of the drug (for
instance, because of clinical trials still ongoing at the time of the evaluation, or when additional clinical trials are needed). This temporary character
may be renewed if an appropriate report to support this is provided by the sponsor. Once the pending studies are provided, it can become a “regular”
marketing authorization.

Approval under exceptional circumstances: a marketing authorization may be granted in exceptional cases, reviewed each year to reassess the risk-
benefit balance when the initial dossier for assessment of the drug cannot contain all required data, when for instance the condition to be treated is
rarely encountered.

Accelerated approval: the evaluation process is accelerated (150 days instead of 210 days) when a drug is of major interest from the standpoint of
public health.

Orphan drugs

Orphan drugs are drugs used for the prevention or treatment of deadly or serious rare conditions. In the United States, the 1983 Orphan Drug Act is intended
to encourage the development of treatments for orphan diseases. The FDA grants the status of orphan drug to any drug aimed at treating diseases affecting
fewer than 200,000 people a year in the United States, or more in cases in which there is no reasonable expectation that the cost of developing and making a
product  available  in  the  United  States  for  treatment  of  the  disease  or  condition  will  be  recovered  from  sales  of  the  product.  The  Orphan  Drug  Act  also
provides the possibility of obtaining grants from the American government to cover clinical trials, tax credits to cover research costs, a possible exemption
from application fees when filing for registration with the FDA, and a seven-year exclusivity if a marketing authorization is granted. If a product with orphan
designation receives the first FDA approval for the disease or condition for which it has such designation or for a select indication or use within the rare
disease or condition for which it was designated, the product generally will receive orphan drug exclusivity. Orphan drug exclusivity means that the FDA
may not approve another sponsor’s marketing application for the same drug for the same indication for seven years, except in certain limited circumstances.
Orphan  exclusivity  does  not  block  the  approval  of  a  different  product  for  the  same  rare  disease  or  condition,  nor  does  it  block  the  approval  of  the  same
product for different indications. If a biologic designated as an orphan drug ultimately receives marketing approval for an indication broader than what was
designated  in  its  orphan  drug  application,  it  may  not  be  entitled  to  exclusivity.  Orphan  exclusivity  will  not  bar  approval  of  another  product  under  certain
circumstances, including if a subsequent product with the same biologic for the same indication is shown to be clinically superior to the approved product on
the basis of greater efficacy or safety, or providing a major contribution to patient care, or if the company with orphan drug exclusivity is not able to meet
market demand.

142

 
 
 
 
 
 
 
 
 
 
 
In Europe, equivalent legislation has been adopted to promote treatments for rare diseases (Regulation 141/2000/EC of December 16, 1999, as amended by
Regulation 847/2000/EC of April 27, 2000). A medicinal product may be designated as orphan if: (a) it is intended for the diagnosis, prevention or treatment
of a life-threatening or chronically debilitating condition affecting not more than five in 10,000 persons in the European Union when the application is made,
or (b) that is intended for the diagnosis, prevention or treatment of a life-threatening, seriously debilitating or serious and chronic condition in the European
Union and that without incentives it is unlikely that the marketing of the medicinal product in the European Union would generate sufficient return to justify
the necessary investment.

For either of these conditions, the applicant must demonstrate that 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  medicinal  product  will  be  of  significant  benefit  to  those  affected  by  that
condition.

Medicinal products receiving orphan designation in the European Union can receive ten years of market exclusivity, during which time no similar medicinal
product may be placed on the market for the same therapeutic indication. An orphan product can also obtain an additional two years of market exclusivity in
the European Union for pediatric studies (in this case for orphan drugs no extension to any supplementary protection certificate can be granted, see further
detail below). Orphan medicinal products are also eligible for financial incentives such as reduction of fees or fee waivers and scientific assistance for study
proposals. (Articles 6 and 9 of the above-mentioned regulation). The application for orphan drug designation must be submitted before the application for
marketing authorization (Article 5). The applicant will receive a fee reduction for the marketing authorization application if the orphan drug designation has
been granted, but not if the designation is still pending at the time the marketing authorization is submitted. Orphan drug designation does not convey any
advantage in, or shorten the duration of, the regulatory review and approval process.

If the product obtains orphan drug status, it is granted an exclusive 10-year marketing period during which no similar product may apply for a marketing
authorization  in  the  European  Union  for  the  same  indication,  as  well  as  an  exemption  from  regulatory  fees  and  other  advantages.  The  10-year  market
exclusivity may be reduced to six years if, at the end of the fifth year, it is established that the product no longer meets the criteria for orphan designation, for
example,  if  the  product  is  sufficiently  profitable  not  to  justify  maintenance  of  market  exclusivity  (Article  8).  However,  marketing  authorization  may  be
granted to a similar medicinal product for the same indication at any time if:

·

·

the holder of the MA for the original orphan medicinal product has given its consent to the second applicant;

the holder of the MA for the original orphan medicinal product cannot supply sufficient quantities of the orphan medicinal product; or

143

 
 
 
 
 
 
 
 
 
 
·

the second applicant can establish in the application that its product, although similar to the orphan medicinal product already authorized, is safer,
more effective or otherwise clinically superior.

Marketing  authorization  may  also  be  granted  to  a  similar  medicinal  product  with  the  same  orphan  indication  if  the  product  is  safer,  more  effective  or
otherwise clinically superior to the original orphan medicinal product. The period of market exclusivity may, in addition, be reduced to six years if 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.

Registration procedures outside of Europe and the United States

In addition to regulation in the United States and Europe, a variety of foreign regulations govern clinical trials, commercial sales and distribution of drugs.
Pharmaceutical  firms  who  wish  to  market  their  medicinal  drugs  outside  the  European  Union  and  the  United  States  must  submit  marketing  authorization
application to the national authorities of the concerned countries, such as the Pharmaceutical and Medical Device Agency, or PMDA in Japan. The approval
process varies from jurisdiction to jurisdiction and the time to approval may be longer or shorter than that required by the FDA or European Commission.

Post-approval regulations

Post-approval regulation in the United States

Biologics manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among other
things,  requirements  relating  to  recordkeeping,  periodic  reporting,  product  sampling  and  distribution,  advertising  and  promotion  and  reporting  of  adverse
experiences with the product. After approval, most changes to the approved product, such as adding new indications or other labeling claims, are subject to
prior FDA review and approval. There also are continuing, annual user fee requirements for any marketed products and the establishments at which such
products are manufactured, as well as new application fees for supplemental applications with clinical data.

In addition, manufacturers and other entities involved in the manufacture and distribution of approved products are required to register their establishments
with  the  FDA  and  state  agencies,  and  are  subject  to  periodic  unannounced  inspections  by  the  FDA  and  these  state  agencies  for  compliance  with  cGMP
requirements. Changes to the manufacturing process are strictly regulated and often require prior FDA approval before being implemented. FDA regulations
also  require  investigation  and  correction  of  any  deviations  from  cGMP  and  impose  reporting  and  documentation  requirements  upon  the  sponsor  and  any
third-party manufacturers that the sponsor may decide to use.

Once an approval is granted, the FDA may withdraw the approval if compliance with regulatory requirements and standards is not maintained or if problems
occur  after  the  product  reaches  the  market.  Later  discovery  of  previously  unknown  problems  with  a  product,  including  adverse  events  of  unanticipated
severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to
add new safety information; imposition of post-market studies or clinical trials to assess new safety risks; or imposition of distribution or other restrictions
under a REMS program. Other potential consequences include, among other things:

·

restrictions on the marketing or manufacturing of the product, suspension of the approval, or complete withdrawal of the product from the market or
product recalls;

144

 
 
 
 
 
 
 
 
 
 
 
 
 
 
·

·

·

·

fines, warning letters or holds on post-approval clinical trials;

refusal of the FDA to approve pending applications or supplements to approved BLAs, or suspension or revocation of product license approvals;

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

injunctions or the imposition of civil or criminal penalties.

In  addition,  the  distribution  of  prescription  pharmaceutical  products  is  subject  to  the  Prescription  Drug  Marketing  Act,  or  PDMA,  and  its  implementing
regulations, as well as the Drug Supply Chain Security Act, or DSCA, which regulate the distribution and tracing of prescription drug samples at the federal
level,  and  set  minimum  standards  for  the  regulation  of  distributors  by  the  states.  The  PDMA,  its  implementing  regulations  and  state  laws  limit  the
distribution of prescription pharmaceutical product samples, and the DSCA imposes requirements to ensure accountability in distribution and to identify and
remove counterfeit and other illegitimate products from the market.

The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Products may be promoted only for the
approved indications and in accordance with the provisions of the approved label. The FDA and other agencies actively enforce the laws and regulations
prohibiting the promotion of off-label uses. Prescription products may be promoted only for the approved indications and in accordance with the provisions
of the approved label. However, companies may also share truthful and not misleading information that is otherwise consistent with the labeling. A company
that is found to have improperly promoted off-label uses may be subject to significant liability.

Patent term restoration and extension in the United States

A  patent  claiming  a  new  biologic  product  may  be  eligible  for  a  limited  patent  term  extension  under  the  Hatch-Waxman  Act,  which  permits  a  patent
restoration of up to five years for patent term lost during product development and the FDA regulatory review. The restoration period granted on a patent
covering a product is typically one-half the time between the effective date a clinical investigation involving human beings is begun and the submission date
of an application, plus the time between the submission date of an application and the ultimate approval date. Patent term extension cannot be used to extend
the remaining term of a patent past a total of 14 years from the product’s approval date. Only one patent applicable to an approved product is eligible for the
extension, the application for the extension must be submitted prior to the expiration of the patent in question, and only those claims covering the approved
drug, a method for using it, or a method for manufacturing it may be extended. A patent that covers multiple products for which approval is sought can only
be  extended  in  connection  with  one  of  the  approvals.  The  USPTO  reviews  and  approves  the  application  for  any  patent  term  extension  or  restoration  in
consultation  with  the  FDA.  For  more  information  regarding  the  risks  related  to  patent  term  restoration  and  extension,  please  see  “Risk  Factors—Risks
Related to Intellectual Property Rights—If we do not obtain protection under the Hatch-Waxman Amendments and similar non-U.S. legislation for extending
the term of patents covering Lumoxiti and each of our product candidates, our business may be materially harmed.”

Healthcare law and regulation in the United States

Healthcare  providers  and  third-party  payors  play  a  primary  role  in  the  recommendation  and  prescription  of  biologic  products  that  are  granted  marketing
approval. Arrangements with providers, consultants, third-party payors and customers are subject to broadly applicable fraud and abuse, anti-kickback, false
claims laws, transparency laws and patient data privacy laws and regulations and other healthcare laws and regulations that may constrain business and/or
financial arrangements. Restrictions under applicable federal and state healthcare laws and regulations, include the following:

·

·

·

·

·

·

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

the U.S. civil and criminal false claims laws, including the civil False Claims Act, and civil monetary penalties laws, which prohibit individuals or
entities  from,  among  other  things,  knowingly  presenting,  or  causing  to  be  presented,  to  the  federal  government,  claims  for  payment  that  are  false,
fictitious or fraudulent or knowingly making, using or causing to made or used a false record or statement to avoid, decrease or conceal an obligation
to pay money to the federal government;

the U.S. Health Insurance Portability and Accountability Act of 1996, or HIPAA, which created additional federal criminal laws that prohibit, among
other  things,  knowingly  and  willfully  executing,  or  attempting  to  execute,  a  scheme  to  defraud  any  healthcare  benefit  program  or  making  false
statements relating to healthcare matters;

HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act,  and  their  respective  implementing  regulations,
including the Final Omnibus Rule published in January 2013, which impose obligations on covered entities and their business associates, including
mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiable health information;

the federal transparency requirements known as the federal Physician Payments Sunshine Act, under the Patient Protection and Affordable Care Act,
as  amended  by  the  Health  Care  Education  Reconciliation  Act,  or  the  ACA,  which  requires  certain  manufacturers  of  drugs,  devices,  biologics  and
medical supplies to report annually to the Centers for Medicare & Medicaid Services, or CMS, within the United States Department of Health and
Human  Services,  information  related  to  payments  and  other  transfers  of  value  made  by  that  entity  to  physicians  and  teaching  hospitals,  as  well  as
ownership and investment interests held by physicians and their immediate family members; and

analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, which may apply to healthcare items or services
that are reimbursed by non-governmental third-party payors, including private insurers.

146

 
 
 
 
 
 
 
 
 
 
 
 
Some  state  laws  require  pharmaceutical  companies  to  comply  with  the  pharmaceutical  industry’s  voluntary  compliance  guidelines  and  the  relevant
compliance guidance promulgated by the federal government in addition to requiring manufacturers to report information related to payments to physicians
and other health care providers or marketing expenditures. Certain state laws require the reporting of information relating to drug and biologic pricing; and
some  state  and  local  laws  require  the  registration  of  pharmaceutical  sales  representatives.  State  and  foreign  laws  also  govern  the  privacy  and  security  of
health  information  in  some  circumstances,  many  of  which  differ  from  each  other  in  significant  ways  and  often  are  not  preempted  by  HIPAA,  thus
complicating compliance efforts.

Failure  to  comply  with  these  laws  or  any  other  governmental  regulations  as  applicable,  could  result  in  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  integrity  reporting  requirements  and  oversight,  as  well  as  contractual  damages,  reputational  harm,  diminished  profits  and  future
earnings, and curtailment of operations.

Healthcare reform in the United States

A primary trend in the United States healthcare industry and elsewhere is cost containment. There have been a number of federal and state proposals during
the  last  few  years  regarding  the  pricing  of  pharmaceutical  and  biopharmaceutical  products,  limiting  coverage  and  reimbursement  for  biologics  and  other
medical products, government control and other changes to the healthcare system in the United States.

By way of example, the United States and state governments continue to propose and pass legislation designed to reduce the cost of healthcare. In March
2010,  the  United  States  Congress  enacted  the  ACA,  which,  among  other  things,  includes  changes  to  the  coverage  and  payment  for  products  under
government health care programs. Among the provisions of the ACA of importance to potential product candidates are:

·

·

an  annual,  nondeductible  fee  on  any  entity  that  manufactures  or  imports  specified  branded  prescription  biologic  agents,  apportioned  among  these
entities  according  to  their  market  share  in  certain  government  healthcare  programs,  although  this  fee  would  not  apply  to  sales  of  certain  products
approved exclusively for orphan indications;

expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to certain individuals with
income at or below 133% of the federal poverty level, thereby potentially increasing a manufacturer’s Medicaid rebate liability;

147

 
 
 
 
 
 
 
 
 
 
 
·

·

·

·

·

·

expanded manufacturers’ rebate liability under the Medicaid Drug Rebate Program by increasing the minimum rebate for both branded and generic
products  and  revising  the  definition  of  “average  manufacturer  price,”  or  AMP,  for  calculating  and  reporting  Medicaid  rebates  on  outpatient
prescription product prices and extending rebate liability to prescriptions for individuals enrolled in Medicare Advantage plans;

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

expanded the types of entities eligible for the 340B drug discount program;

established  the  Medicare  Part  D  coverage  gap  discount  program  by  requiring  manufacturers  to  now  provide  a  70%  point-of-sale-discount  off  the
negotiated price of applicable brand products to eligible beneficiaries during their coverage gap period as a condition for the manufacturers’ outpatient
products to be covered under Medicare Part D;

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

established the Center for Medicare and Medicaid Innovation within CMS to test innovative payment and service delivery models to lower Medicare
and Medicaid spending, potentially including prescription product spending.

There have been judicial and Congressional challenges to certain aspects of the ACA, as well as recent efforts by the Trump administration to repeal and
replace  certain  aspects  of  the  ACA,  and  we  expect  such  challenges  to  continue.  Since  January  2017,  President  Trump  has  signed  two  executive  orders
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 has considered legislation that would repeal or repeal and replace all or part of the ACA. While Congress has not passed
comprehensive repeal legislation, two bills affecting the implementation of certain taxes under the ACA have been signed into law. The Tax Cuts and Jobs
Act  of  2017  includes  a  provision  that  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.” In addition, 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. In July and December 2018, CMS published
final rules with respect to permitting further collections and payments to and from certain ACA qualified health plans and health insurance issuers under its
risk adjustment program in response to the outcome of federal district court litigation regarding the method CMS uses to determine this risk adjustment. On
December 14, 2018, a Texas U.S. District Court Judge ruled that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed
by the U.S. Congress as part of the Tax Cuts and Jobs Act of 2017 Additionally, on December 18, 2019, the U.S. Court of Appeals for the 5th Circuit upheld
the  District  Court  ruling  that  the  individual  mandate  was  unconstitutional  and  remanded  the  case  back  to  the  District  Court  to  determine  whether  the
remaining provisions of the ACA are invalid as well. It is unclear how this decision, subsequent appeals, and other efforts to repeal and replace the ACA will
impact the ACA. We continue to evaluate how the ACA and recent efforts to limit the implementation of the ACA will impact our business.

148

 
 
 
 
 
 
 
 
 
 
 
Other legislative changes have been proposed and adopted in the United States since the ACA was enacted. For example, in August 2011, the Budget Control
Act  of  2011,  among  other  things,  created  measures  for  spending  reductions  by  Congress.  A  Joint  Select  Committee  on  Deficit  Reduction,  tasked  with
recommending a targeted deficit reduction of at least $1.2 trillion for the years 2012 through 2021, was unable to reach required goals, thereby triggering the
legislation’s automatic reduction to several government programs. This includes aggregate reductions of Medicare payments to providers of up to 2% per
fiscal year, which went into effect in April 2013 and will remain in effect through 2027 unless additional Congressional action is taken. In January 2013,
President  Obama  signed  into  law  the  American  Taxpayer  Relief Act  of  2012,  which,  among  other  things,  further  reduced  Medicare  payments  to  several
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.

Further, there has been increasing legislative and enforcement interest in the United States with respect to drug pricing practices. Specifically, there have
been  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 drugs. At the federal level, the Trump administration’s budget proposal for fiscal year 2020
contains further drug price control measures that could be enacted during the budget process or in other future legislation. The Trump administration also
released  a  “Blueprint”,  or  plan,  to  lower  drug  prices  and  reduce  out  of  pocket  costs  of  drugs  that  contains  additional  proposals  to  increase  manufacturer
competition, increase the negotiating power of certain federal healthcare programs, incentivize manufacturers to lower the list price of their products and
reduce the out of pocket costs of drug products paid by consumers. For example, in May 2019, CMS issued a final rule to allow Medicare Advantage Plans
the option of using step therapy for Part B drugs beginning January 1, 2020. This final rule codified CMS’s policy change that was effective January 1, 2019.
While some measures may require additional authorization to become effective, the U.S. Congress and the Trump administration have each indicated that it
will continue to seek new legislative and/or administrative measures to control drug costs. At the state level, legislatures are increasingly passing legislation
and  implementing  regulations  designed  to  control  pharmaceutical  and  biological  product  pricing,  including  price  or  patient  reimbursement  constraints,
discounts,  restrictions  on  certain  product  access  and  marketing  cost  disclosure  and  transparency  measures,  and,  in  some  cases,  designed  to  encourage
importation from other countries and bulk purchasing.

149

 
 
 
 
 
 
Pharmacovigilance system in Europe

The holder of a European MA must establish and maintain a pharmacovigilance system and appoint an individual qualified person for pharmacovigilance, or
QPPV, 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 European MA applications 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. RMPs and PSURs are routinely available to third parties requesting
access, subject to limited redactions.

Advertising regulation in Europe

All advertising and promotional activities for the product must be consistent with the approved summary of product characteristics, and therefore all off-label
promotion is prohibited. Direct-to-consumer advertising of prescription medicines is also prohibited in the European Union. Although general requirements
for  advertising  and  promotion  of  medicinal  products  are  established  under  European  Union  directives,  the  details  are  governed  by  regulations  in  each
European Union Member State and can differ from one country to another.

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.

Pharmaceutical coverage, pricing and reimbursement

European Union

In the European Union, pricing and reimbursement schemes vary widely from country to country. Some countries provide that products may be marketed
only after a reimbursement price has been agreed. Some countries may require the completion of additional studies that compare the cost-effectiveness of a
particular product candidate to currently available therapies or so called health technology assessments, in order to obtain reimbursement or pricing approval.
For example, the European Union provides options for its member states to restrict the range of products for which their national health insurance systems
provide reimbursement and to control the prices of medicinal products for human use. European Union member states may approve a specific price for a
product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the product on the market. Other member
states  allow  companies  to  fix  their  own  prices  for  products,  but  monitor  and  control  prescription  volumes  and  issue  guidance  to  physicians  to  limit
prescriptions. Recently, many countries in the European Union have increased the amount of discounts required on pharmaceuticals and these efforts could
continue as countries attempt to manage healthcare expenditures, especially in light of the severe fiscal and debt crises experienced by many countries in the
European Union. The downward pressure on health care costs in general, particularly prescription products, has become intense. As a result, increasingly
high barriers are being erected to the entry of new products. Political, economic and regulatory developments may further complicate pricing negotiations,
and  pricing  negotiations  may  continue  after  reimbursement  has  been  obtained.  Reference  pricing  used  by  various  European  Union  member  states,  and
parallel trade, i.e., arbitrage between low-priced and high-priced member states, can further reduce prices. 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 products,
if approved in those countries.

150

 
 
 
 
 
 
 
 
 
 
 
 
 
United States

In the United States, patients who are prescribed treatments for their conditions and providers performing the prescribed services generally rely on third-party
payors  to  reimburse  all  or  part  of  the  associated  healthcare  costs.  Significant  uncertainty  exists  as  to  the  coverage  and  reimbursement  status  of  products
approved by the FDA and other government authorities. Thus, even if a product candidate is approved, sales of the product will depend, in part, on the extent
to  which  third-party  payors,  including  government  health  programs  in  the  United  States  such  as  Medicare  and  Medicaid,  commercial  health  insurers  and
managed care organizations, provide coverage, and establish adequate reimbursement levels for, the product. The process for determining whether a payor
will provide coverage for a product may be separate from the process for setting the price or reimbursement rate that the payor will pay for the product once
coverage  is  approved.  Third-party  payors  are  increasingly  challenging  the  prices  charged,  examining  the  medical  necessity,  and  reviewing  the  cost-
effectiveness  of  medical  products  and  services  and  imposing  controls  to  manage  costs.  Third-party  payors  may  limit  coverage  to  specific  products  on  an
approved list, also known as a formulary, which might not include all of the approved products for a particular indication.

In  order  to  secure  coverage  and  reimbursement  for  any  product  that  might  be  approved  for  sale,  a  company  may  need  to  conduct  expensive
pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of the product, in addition to the costs required to obtain
FDA or other comparable marketing approvals. Nonetheless, product candidates may not be considered medically necessary or cost effective. A decision by
a third-party payor not to cover a product candidate could reduce physician utilization once the product is approved and have a material adverse effect on
sales,  results  of  operations  and  financial  condition.  Additionally,  a  payor’s  decision  to  provide  coverage  for  a  product  does  not  imply  that  an  adequate
reimbursement rate will be approved. Further, one payor’s determination to provide coverage for a product does not assure that other payors will also provide
coverage and reimbursement for the product, and the level of coverage and reimbursement can differ significantly from payor to payor.

The containment of healthcare costs also has become a priority of federal, state and foreign governments and the prices of products have been a focus in this
effort. Governments have shown significant interest in implementing cost-containment programs, including price controls, restrictions on reimbursement 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  a  company’s  revenue  generated  from  the  sale  of  any  approved  products.  Coverage
policies  and  third-party  reimbursement  rates  may  change  at  any  time.  Even  if  favorable  coverage  and  reimbursement  status  is  attained  for  one  or  more
products for which a company or its collaborators receive marketing approval, less favorable coverage policies and reimbursement rates may be implemented
in the future.

151

 
 
 
 
 
 
 
 
Anti-corruption, anti-kickback and transparency regulations

Arrangements with healthcare providers, physicians, third-party payors and customers can expose pharmaceutical manufactures to broadly applicable anti-
bribery, fraud and abuse and other healthcare laws and regulations, which may constrain the business or financial arrangements and relationships through
which such companies sell, market and distribute pharmaceutical products.

More specifically, each of the above-mentioned steps of the development of therapeutic products for human use is heavily regulated and therefore involves
significant interaction with public officials which is likely to cause a risk of corruption or bribery. For instance, in many countries, hospitals are operated by
the government, and doctors and other hospital employees are considered foreign officials. Certain payments to hospitals in connection with clinical trials
and other work have been deemed to be improper payments to government officials and have led to enforcement actions. That is why business activity may
be  subject  to  anti-bribery  or  anti-corruption  laws,  regulations  or  rules  of  other  countries  in  which  we  operate,  including  without  limitation  the  Foreign
Corrupt Practices Act, the U.K. Bribery Act or the French Sapin 2 Law.

All these statutes generally prohibit offering, promising, giving, or authorizing others to give anything of value, either directly or indirectly, to a government
or a foreign government official or employees of public international organizations in order to influence official action, or otherwise obtain or retain business.
The  implementation  of  these  statutes  may  also  impose  to  develop  internal  compliance  programs,  procedures  and  guidelines  to  detect  and  report  any
suspicious activities and to mitigate any risks of noncompliance which may occur.

In addition, we may be subject to specific healthcare regulations, including, without limitation:

·

·

the  French  “transparency”  provisions,  or  “French  Sunshine  Act”  (Articles  L.  1453-1  and  D.  1453-1  and  seq.  of  the  French  Public  Health  Code  or
PHC),  which  contains  provisions  regarding  transparency  of  fees  received  by  some  healthcare  professionals  from  industries,  i.e.  companies
manufacturing or marketing healthcare products (medicinal products, medical devices, etc.) 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 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, 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 healthcare professionals, with limited exceptions and strictly defines the conditions under
which such payments or awards are lawful.

Data protection rules

The Regulation 2016/679, known as the General Data Protection Regulation, or GDPR, that came into force on May 25, 2018, as well as EU Member State
implementing legislations, apply to the collection and processing of personal data, including health-related information, by companies located in the EU, or
in certain circumstances, by companies located outside of the EU and processing personal information of individuals located in the EU.

152

 
 
 
 
 
 
 
 
 
 
 
 
 
These laws impose strict obligations on the ability to process personal data, including health-related information, in particular in relation to their collection,
use, disclosure and transfer.

Also, in certain countries, in particular France, the conduct of clinical trials is subject to compliance with specific provisions of the Act No.78-17 of January
6, 1978 on Information Technology, Data Files and Civil Liberties, as amended, and in particular Chapter IX relating to the processing of personal data in the
health  sector.  These  provisions  require,  among  others,  the  filing  of  compliance  undertakings  with  “standard  methodologies”  adopted  by  the  French  Data
Protection Authority (the CNIL), or, if not complying, obtaining a specific authorization from the CNIL.

The most common standard methodologies are the following:

·

·

D.       Property, Plants and Equipment.

Our corporate offices and laboratories are located in Luminy, near Marseille, France. In 2008, we signed a lease-financing agreement with SOGEBAIL, a
subsidiary  of  Société  Générale,  for  €6.6  million  to  finance  the  acquisition  of  our  offices.  The  lease-financing  agreement  has  a  12-year  term.  We  have  a
purchase  option  for  all  of  the  buildings  and  land  for  the  lump  sum  of  €1  at  the  end  of  the  term  of  the  lease-financing  agreement  on  June  9,  2020.  In
accordance with the terms of the lease-financing agreement, we exercised this buy-back option and will sign the deed of sale before notary. We believe that
our existing facilities are adequate to meet our current needs and that suitable additional alternative facilities will be available in the future on commercially
reasonable terms to meet our future needs.

Item 5. Operating and Financial Review and Prospects.

You should read the following discussion of our financial condition and results of operations in conjunction with the “Selected Consolidated Financial Data”
and our 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 “Item 3.D – Risk Factors” and “Special Note Regarding Forward-
Looking Statements.” Our audited consolidated financial statements as of and for the years ended December 31, 2017, 2018 and 2019 have been prepared in
accordance  with  IFRS  as  issued  by  the  IASB,  which  may  differ  in  material  respects  from  generally  accepted  accounting  principles  in  other  jurisdictions,
including the United States.

Overview

We  are  a  biotechnology  company  focused  on  discovering,  developing  and  commercializing  first-in-class  therapeutic  antibodies  designed  to  harness  the
immune system for the treatment of oncology indications with significant unmet medical need. We have extensive experience in research and development in
immuno-oncology,  having  been  pioneers  in  the  understanding  of  natural  killer  cell,  or  NK  cell,  biology,  and  later  expanding  our  expertise  in  the  tumor
microenvironment, tumor antigens and antibody engineering fields. We have built, internally and through our business development strategy, a broad and
diversified portfolio including an approved product, four clinical product candidates and a robust preclinical pipeline. We have entered into collaborations
with  leaders  in  the  biopharmaceutical  industry,  such  as  AstraZeneca  and  Sanofi,  to  leverage  their  development  capabilities  and  expertise  for  some  of  our
candidates. We believe our product candidates and clinical development approach are differentiated from current immuno-oncology therapies and have the
potential to significantly improve the clinical outcome for patients with cancer.

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. Our
marketed  product,  Lumoxiti,  was  approved  by  the  U.S.  Food  and  Drug  Administration,  or  FDA,  under  priority  review  in  September  2018  and  was
commercially launched by AstraZeneca AB, or AstraZeneca, in November 2018. We have not yet generated any material revenue from product sales. We
have  funded  our  operations  to  date  primarily  through  private  and  public  offerings  of  ordinary  shares,  payments  from  our  collaborators  and  research  tax
credits.

154

 
 
 
 
 
 
 
 
 
 
 
As of December 31, 2019, we had €255.9 million in cash, cash equivalents, short-term investments and non-current financial assets. Since our inception, we
have  raised  a  total  of  €306.4  million  through  the  sale  of  equity  securities,  including  €33.7  million  in  the  initial  public  offering  of  our  ordinary  shares  on
Euronext Paris in 2006 and €66.0 million in the initial public offering of our ordinary shares on Euronext and ADS on Nasdaq New-York in 2019. We have
also  received  $475.0  million  (€415.9  million)  in  payments  from  our  collaborators,  including  AstraZeneca,  since  2011,  excluding  payments  received  for
purchases of our equity securities by our collaborators.

We  have  significant  agreements  with  AstraZeneca  pursuant  to  which  we  have  the  right  to  earn  milestone  and  royalty  payments.  We  have  other  license
agreements pursuant to which we have acquired intellectual property and under which we will be required to make payments to the counterparty upon the
achievement of certain milestone events and commercial sales related to our product candidates.

We have incurred net losses in each year since our inception except for the years ended December 31, 2016 and 2018. Our net income (loss) was €(48.4)
million,  €3.0  million  and  €(20.8)  million  for  the  years  ended  December  31,  2017,  2018  and  2019,  respectively.  Substantially  all  of  our  net  losses  have
resulted from costs incurred in connection with our research and development programs and from selling, general and administrative expenses associated
with our operations. As we continue advancing our product candidates through research and development programs and investing in the commercialization
of Lumoxiti, we expect to continue to incur significant expenses and may again incur operating losses in future periods. We anticipate that such expenses will
increase substantially if and as we:

·

·

·

·

·

·

·

·

·

·

·

continue the research and development of our product candidates;

initiate clinical trials for, or additional preclinical development of, our product candidates;

further develop and refine the manufacturing processes for our product candidates;

change or add manufacturers or suppliers of biological materials;

seek regulatory and marketing authorizations for any of our product candidates that successfully complete development;

establish  a  sales,  marketing  and  distribution  infrastructure  to  commercialize  Lumoxiti  and  any  other  products  for  which  we  may  obtain  marketing
authorization;

seek to identify and validate additional product candidates;

acquire or license other product candidates, technologies or biological materials;

make milestone, royalty or other payments under any current or future license agreements;

obtain, maintain, protect and enforce our intellectual property portfolio;

secure manufacturing arrangements for commercial production;

155

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
·

·

·

seek to attract and retain new and existing skilled personnel;

create additional infrastructure to support our operations as a U.S. public company and incur increased legal, accounting, investor relations and other
expenses; and

experience delays or encounter issues with any of the above.

We anticipate that we will need to raise additional funding, prior to completing clinical development of any of our product candidates. Until such time that
we can generate significant revenues from sales of Lumoxiti and our product candidates, if approved, we expect to finance our operating activities through a
combination of milestone payments received pursuant to our strategic alliances, equity offerings, debt financings, government or other third-party funding
and collaborations, and licensing arrangements. However, we may not receive milestone payments when expected, or at all, and we may be unable to raise
additional funds or enter into such 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 to others rights to develop or market
product candidates that we would otherwise prefer to develop and market ourselves. Failure to receive additional funding could cause us to cease operations,
in part or in full.

Presentation of Financial Information

Our  audited  consolidated  financial  statements  included  herein  as  of  and  for  the  years  ended  December  31,  2017,  2018  and  2019  have  been  prepared  in
accordance with IFRS as issued by the IASB.

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, we also
prepare and publish our consolidated financial statements in accordance with IFRS as adopted by the European Union, or EU.

All the standards published by the IASB that are mandatorily applicable in the years ended December 31, 2017, 2018 and 2019 are endorsed by the EU and
are mandatorily applicable in the EU. Therefore, our audited consolidated financial statements for the years ended December 31, 2017, 2018 and 2019 are
compliant with both IFRS as issued by the IASB and IFRS as adopted by the EU.

The preparation of financial statements in accordance with IFRS requires us to make significant judgments and estimates which are presented below. See “—
Critical Accounting Policies and Significant Judgments and Estimates.”

Our Principal Collaboration and Licensing Agreements

Our results of operations are impacted by the terms and conditions of our principal collaboration and licensing agreements. For a description of our principal
collaboration and licensing agreements, see “Item 10C.—Material Contracts.”

Our Principal Components of Our Results of Operations

Revenue and other income

Our revenue and other income mainly consists of revenues from collaboration and licensing agreements and government financing for research expenditure
in the form of the research tax credits, as well as other grants.

156

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Revenue from collaboration and licensing agreements

We  currently  derive  substantially  all  our  revenues  from  payments  pursuant  to  our  licensing  and  collaboration  agreements  with  AstraZeneca  relating  to
monalizumab  and  IPH5201,  consisting  of  (i)  upfront  payments,  (ii)  milestone  payments  based  upon  the  achievement  of  pre-determined  development,
regulatory  and  commercial  events  and  (iii)  research  and  development  fees  related  to  charges  for  full  time  equivalents,  or  FTEs,  at  contracted  rates  and
reimbursement of research and development expenses.

We have not generated any revenue from product sales since our inception, with the exception in 2019 and 2018 of Lumoxiti sales, which were classified in
the net income (loss) from distribution agreements during the transition period with AstraZeneca. Our ability to generate significant product revenue and to
become profitable will depend upon our ability to successfully commercialize Lumoxiti and our ability to successfully develop, obtain regulatory approval
for and commercialize any other product candidates. Because of the numerous risks and uncertainties associated with product development and regulatory
approval, we are unable to predict the amount, timing or whether we will be able to obtain product revenue.

On January 1, 2018, IFRS 15 Revenue from contracts with customers, or IFRS 15, became mandatorily applicable.

IFRS 15 supersedes IAS 11 Construction contracts, IAS 18 Revenue, or IAS 18, and related interpretations, and changes the accounting treatment of the
revenue  relating  to  our  agreement  with  AstraZeneca  with  respect  to  monalizumab.  Under  IFRS  15,  our  co-funding  share  of  research  and  development
expenses incurred by AstraZeneca is no longer recorded as research and development expense, but rather is deducted from the recognition of the upfront
payment received by us upon execution of the agreement. The amount of our co-funding obligation is now recognized as a collaboration liability and is no
longer recorded as deferred revenue in the consolidated statement of financial position. When the collaboration liability is in a foreign currency, which is the
case in the context of this agreement, it is translated at each reporting date using the closing exchange rate, which generates foreign exchange gains or losses
in our consolidated statement of income (loss).

We  have  opted  for  the  modified  retrospective  approach  without  any  of  the  practical  expedients  allowed  by  IFRS  15.  Accordingly,  the  comparative
information  is  not  restated  and  the  cumulative  impact  of  the  first  application  is  presented  as  an  adjustment  of  the  opening  equity  as  of  January  1,  2018.
Consequently,  the  first  application  of  IFRS  15  may  affect  the  comparability  of  our  revenue  and  research  and  development  expenses  for  the  years  ended
December 31, 2017, 2018 and 2019.

Since January 1, 2018, agreements are analyzed according to IFRS 15. For our agreements relating to monalizumab and IPH5201, we have concluded that
the license is not distinct from the research and development services because those services increase the utility of the license. As a result, the estimated
transaction price is spread over the period when we are engaged to deliver services to AstraZeneca based on the percentage of completion of the costs to be
incurred, and non-refundable initial payments received are deferred and recognized as revenue over time.

Variable  consideration  can  be  included  in  the  estimated  transaction  price  only  if  it  is  highly  probable  that  the  related  revenue  will  not  be  reversed  in  the
future. According to the level of uncertainty relating to the results of preclinical studies and clinical trials and the decisions relating to regulatory approvals,
related  payments  are  excluded  from  the  transaction  price  as  long  as  the  triggering  event  is  not  certain.  If  and  when  the  triggering  event  occurs,  the
corresponding milestone is added to the transaction price and revenue is recognized relative to the percentage of completion related to the transaction.

157

 
 
 
 
 
 
 
 
 
 
 
When a collaboration contract grants to the collaborator an option to acquire a license, we exercise judgment to determine the beginning date of transfer of
the control of the license. Depending on the situation, the recognition of the revenue begins from the date of the contract, with the payment relating to the
exercise of the option being therefore considered as variable consideration, or the recognition is deferred until the exercise or expiration of the option.

In addition, under the agreements with AstraZeneca relating to IPH5201 and avdoralimab, we are reimbursed for some of our internal and external costs. We
recognize these reimbursements as revenue in our consolidated statement of income (loss) when the related costs are incurred.

Revenue  recognition  involves  significant  judgments  and  estimates  by  management.  See  “—Critical  Accounting  Policies  and  Significant  Judgments  and
Estimates.”

Prior to 2018, revenue was recognized in accordance with IAS 18, which resulted in a difference in revenue recognition accounting policies used for the
audited consolidated financial statements for the years ended December 31, 2017, 2018 and 2019.

Government financing for research expenditures

Our government financing for research expenditures consists of research tax credits (crédit d’impôt recherche) and grants.

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 demonstrating that they have expenses that meet the required criteria, including research expenses located in France or, since January 1, 2005,
within the EU 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 for 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 expenditures taken into account for the
calculation of the research tax credit involve only research expenses.

The main characteristics of the research tax credit are:

·

·

·

the research tax credit results in a cash inflow to us from the tax authorities, i.e., it is used to offset the payment of corporate tax or is paid directly to
us for the portion that remains unused the year after the date of its record as a tax credit in the income statement;

our corporate income tax liability does not limit the amount of the research tax credit—if we do not pay any corporate income tax, we can request
direct cash payment of the research tax credit the year following its record in the income statement; and

the research tax credit is not included in the determination of the corporate income tax.

When the research tax credit is not deductible from taxes payable by us, it is generally reimbursed by the French government three years after the fiscal year
for  which  it  is  determined.  However,  since  2011,  companies  that  meet  the  definition  of  small  and  medium  sized  enterprises  (“SMEs”)  according  to  the
European Union criteria are eligible for early reimbursement of their research tax credit receivable. The status of SME is lost when the criteria for eligibility
are exceeded during two consecutive years. We lost our status as an SME at the end of the fiscal year 2019.

158

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We  have  concluded  that  the  research  tax  credit  meets  the  definition  of  a  government  grant  as  defined  in  IAS  20  Accounting  for  government  grants  and
disclosure of government assistance, or IAS 20, and that the classification as “Revenue and other income” in our consolidated statement of income (loss) is
appropriate.

We  also  from  time  to  time  receive  government  grants,  which  are  recognized  in  our  consolidated  statement  of  income  (loss)  when  we  comply  with  the
conditions attached to the grants and they are non-repayable grants.

Operating expenses

Since inception, our operating expenses have consisted primarily of research and development expenses and selling, general and administration expenses.

Research and development expenses

We engage in substantial research and development efforts to develop innovative product candidates. Research and development expenses consist primarily
of:

·

·

·

·

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

cost of third-party contractors and academic institutions involved in preclinical studies or clinical trials that we may conduct, or third-party contractors
involved in field trials;

purchases of biological raw materials, real estate leasing costs as well as conferences and travel costs; and

certain other expenses, such as expenses for use of laboratories and facilities for our research and development activities as well as depreciation and
amortization.

Our  research  and  development  efforts  are  focused  on  our  existing  product  candidates  and  preclinical  programs,  including  the  advancement  of  our  lead
product candidates, monalizumab, lacutamab and avdoralimab. Our direct research and development expenses consist principally of external costs associated
with subcontracting of preclinical and clinical operations to third parties, which we track on a program-by-program basis. We also use our employee and
infrastructure resources across multiple research and development programs, and do not track these indirect expenses on a program-by-program basis.

Research and development costs are expensed as incurred. Costs for certain activities are recognized based on an evaluation of the progress to completion of
specific tasks using data such as information provided to us by our vendors and analyzing the progress of our preclinical studies or other services performed.
Significant  judgment  and  estimates  are  made  in  determining  the  accrued  expense  balances  at  the  end  of  any  reporting  period.  Non-refundable  advance
payments for research and development goods or services to be received in the future from third parties are deferred and capitalized. The capitalized amounts
are expensed as the related goods are delivered or the services are performed.

159

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Research  and  development  activities  are  central  to  our  business.  As  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 costs will increase in the foreseeable future. Such cost increases are expected to occur as we conduct existing clinical trials
and initiate future clinical trials, manufacture pre-commercial clinical trial and preclinical study materials, expand our research and development efforts, seek
regulatory  approvals  for  our  product  candidates  that  successfully  complete  clinical  trials,  access  and  develop  additional  technologies  and  hire  additional
personnel to support our research and development efforts.

We cannot determine with certainty the duration and total costs of our future clinical trials of our product candidates or if, when, or to what extent we will
generate revenues from the commercialization and sale of any of our product candidates, or those of our collaborators, that might 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  clinical  trials  as  well  as  any  additional  preclinical  studies,  clinical  trials  conducted  by  our
collaborators and other research and development activities;

clinical trial and preclinical study results;

the terms and timing of regulatory approvals;

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

the ability to market, commercialize and achieve market acceptance for any products that receive regulatory approval.

A  change  in  the  outcome  of  any  of  these  variables  with  respect  to  the  development  of  monalizumab,  lacutamab  and  avdoralimab  or  any  other  product
candidate or preclinical program that we are developing or could develop in the future could mean a significant change in the costs and timing associated
with the development of such product candidates or preclinical programs. For example, if the FDA, the European Medicines Agency, or EMA, or another
regulatory  authority  were  to  require  us  to  conduct  preclinical  studies  and  clinical  trials  beyond  those  that  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. For a discussion of the risks associated with completing the development
projects on schedule, see “Risk Factors—Risks Related to the Development and Commercialization of Lumoxiti and Our Product Candidates.”

160

 
 
 
 
 
 
 
 
 
 
 
 
Selling, general and administrative expenses

Selling,  general  and  administrative  expenses  consist  primarily  of  personnel  costs  and  share-based  compensation  for  personnel  other  than  research  and
development  staff.  Selling,  general  and  administrative  expenses  also  consist  of  fees  for  professional  services,  mainly  related  to  audit,  IT,  accounting,
recruitment and legal services, communication and travel costs, real-estate leasing costs, office furniture and equipment costs, allowance for amortization and
depreciation, director’s attendance fees and insurance costs and overhead costs, such as postal and telecommunications expenses.

We anticipate that our selling, general and administrative expense will increase in the future as we grow our support functions for the expected increase in
our  research  and  development  activities  and  the  commercialization  of  Lumoxiti.  Our  share  of  Lumoxiti  operational  expenses  are  included  in  net  income
(loss) from distribution agreements because AstraZeneca has been responsible for commercialization activities to date. However, we have directly incurred
operational  expenses  related  to  Lumoxiti  in  the  year  ended  December  31,  2019  and  we  will  expect  to  incur  additional  operational  expenses  related  to
Lumoxiti  in  the  future.  These  operational  expenses  consist  mainly  of  selling,  general  and  administrative  expenses.  We  also  anticipate  increased  expenses
associated with being a public company in the United States, including costs related to strengthening our support functions and hiring additional staff as well
as  our  audit,  legal,  regulatory  and  tax-related  services  associated  with  maintaining  compliance  with  Nasdaq  listing  and  SEC  requirements,  director  and
officer insurance premiums and investor relations costs.

Net income (loss) from distribution agreements

When commercialization activities related to a product that we own or license are performed by a third-party under a collaboration or transition agreement,
we must determine if the collaborator acts as an agent or a principal. With respect to our agreement with AstraZeneca related to Lumoxiti, we concluded that
AstraZeneca acted as principal during the periods presented because AstraZeneca controls the commercialization activities and is the holder of the applicable
regulatory marketing authorization.

As  a  result,  we  recognize  on  a  single  line  the  net  income  (loss)  from  our  Lumoxiti  distribution  agreement  in  an  amount  equal  to  the  sales  for  the  period
(which were modest for the fiscal years ended December 31, 2018 and 2019), net of the administrative and selling expenses associated with the sales revenue
allocated to us.

Net financial income (loss)

Our financial loss primarily consists of realized and unrealized foreign exchange gains and losses primarily related to the purchase of services as well as
deposit accounts denominated in U.S. dollars and gains and losses and interest received in relation to cash and cash equivalents that have been deposited in
cash  accounts,  short-term  fixed  deposits  and  short-term  highly  liquid  investments  with  original  maturities  of  three  months  or  less.  Our  cash  and  cash
equivalents generate a modest amount of interest income. We expect to continue this investment philosophy in the future.

Proceeds related to monalizumab. Revenue related to monalizumab decreased by €19.0 million, or 30.9%, to €42.5 million for the year ended December 31,
2019, as compared to €61.5 million for the year ended December 31, 2018. This change is primarily due to the one-off impact of the exercise of the option by
AstraZeneca ($100.0 million) in October 2018, which generated a catch-up impact in revenue of €32.0 million and €6.4 million in the years ended December
31,  2018  and  2019,  respectively.  As  of  December  31,  2019,  the  deferred  revenue  related  to  monalizumab  is  €62.7  million  (€39.7  million  as  “Deferred
revenue—Current portion” and €22.9 million as “Deferred revenue—Non-current portion”).

Proceeds related to IPH5201. Revenue related to IPH5201 increased by €3.2 million, or 20.4%, to €18.8 million for the year ended December 31, 2019, as
compared to €15.6 million for the year ended December 31, 2018. This change is primarily due to revenue related to the partial recognition in 2019 of the
$50.0  million  non-refundable  upfront  payment  received  from  AstraZeneca  in  2018,  which  has  been  recognized  as  revenue  based  on  the  percentage  of
completion of the development work. As of December 31, 2019, the amount not yet recognized in revenue amounted to €9.1 million, classified as “Deferred
revenue—Current portion.”

Invoicing of research and development costs. Revenue from invoicing of research and development costs for the year ended December 31, 2019 was €6.9
million compared to €2.2 million for the year ended December 31, 2018. Pursuant to our agreements with AstraZeneca, clinical costs for the ongoing Phase I
trial of avdoralimab in combination with durvalumab are equally shared between us and AstraZeneca and research and development costs related to IPH5201
are fully borne by AstraZeneca, resulting in periodic settlement invoices.

Government financing for research expenditures

Government financing for research expenditures increased by €2.8 million, or 19.8%, to €16.8 million for the year ended December 31, 2019, as compared to
€14.1 million for the year ended December 31, 2018. This change is primarily a result of an increase in the research tax credit of €3.2 million, which is
mainly due to an increase in the amortization expense relating to the intangible assets related to the licenses acquired from AstraZeneca in October 2018. The
table below details government funding for research expenditures for the years ended December 31, 2018 and 2019.

  Lumoxiti research and development expenses mainly relate to the generation of additional clinical data and the preparation of the submission of the marketing authorization application

to the EMA.

Research  and  development  increased  by  €9.3  million,  or  13.4%,  to  €78.9  million  for  the  year  ended  December  31,  2019,  as  compared  to  research  and
development  of  €69.6  million  for  the  year  ended  December  31,  2018.  This  increase  change  is  primarily  a  result  of  an  increase  of  €11.0  million  euros  in
personnel and other expenses, partly offset by a decrease of €1.7 million euros in direct research and development expenses (clinical and non-clinical).

Research  and  development  expenses  represented  a  total  of  79.4%  and  75.3%  of  the  total  operation  expenses  for  the  years  ended  December  31,  2018  and
2019, respectively. As of December 31, 2018, we had 154 employees in research and development functions, compared to 162 as of December 31, 2019.

Direct research and development expenses decreased by €1.7 million, or 3.9%, to €44.4 million for the year ended December 31, 2019, as compared to direct
research and development expenses of €46.1 million for the year ended December 31, 2018. This change is primarily a result of: (i) a €5.1 million decrease in
expenses  related  to  the  lacutamab  program,  (ii)  a  €4.0  million  decrease  in  expenses  related  to  the  avdoralimab  program,  (iii)  a  €2.6  million  decrease  in
expenses  related  to  the  monalizumab  program,  partially  offset  by  (iv)  a  €10.6  million  increase  in  expenses  related  to  the  acquisition  of  Lumoxiti.  The
decrease  in  expenses  related  to  the  lacutamab  and  avdoralimab  programs  mainly  results  from  €7.5  million  decrease  in  chemical,  manufacturing  and
production control costs due to the phasing of the production on batches.

Personnel and other expenses increased by €11.0 million, or 47.1%, to €34.3 million for the year ended December 31, 2019, as compared to personnel and
other expenses of €23.4 million for the year ended December 31, 2018. This change is primarily a result of (i) a €8.8 million increase in depreciation and
amortization expenses due to the full year impact of the amortization of Lumoxiti (€2.3 million) and IPH5201 (€6.5 million) and (ii) a €1.7 million increase
in  personnel  expenses  (including  share-based  compensation)  due  to  the  increase  in  employee  headcount  and  bonuses  (€1.4  million)  and  share-based
payments (€0.3 million).

Selling, general and administrative expenses

Selling, general and administrative expenses increased by €7.7 million, or 42.2%, to €25.8 million for the year ended December 31, 2019, as compared to
€18.1  million  for  the  year  ended  December  31,  2018.  Selling,  general  and  administrative  expenses  represented  a  total  of  20.7%  and  24.7%  of  our  total
operating expenses for the years ended December 31, 2018 and 2019, respectively.

Personnel expenses, which includes the compensation paid to our employees and consultants, increased by €3.0 million, or 39.1%, to €10.6 million for the
year ended December 31, 2019, as compared to personnel expenses of €7.6 million for the year ended December 31, 2018. This increase mainly results from
an increase in wages and salaries of €2.1 million, resulting from the recruitment of employees for our US subsidiary (€1.7 million), including employees
affected to the commercialization of Lumoxiti. As of December 31, 2019, we had 65 employees in general and administrative functions, as compared to 41
as of December 31, 2018. This change is primarily a result of the recruitment of 20 employees for our US subsidiary.

Non-scientific  advisory  and  consulting  expenses  mostly  consist  of  auditing,  accounting,  taxation  and  legal  fees  as  well  as  consulting  fees  in  relation  to
business strategy and operations and hiring services. Non-scientific advisory and consulting expenses increased by €3.1 million, or 58.1%, to €8.4 million for
the year ended December 31, 2019 as compared to €5.3 million for the year ended December 31, 2018. This increase mainly results from fees incurred for
the commercialization of Lumoxiti and the development of the activities of our US affiliate.

Net income (loss) from distribution agreements

We recognized a net loss of €8.2 million from the Lumoxiti distribution agreement in the year ended December 31, 2019, as compared to a net loss of €1.1
million  for  the  year  ended  December  31,  2018,  which  reflected  revenue  from  sales  of  Lumoxiti  in  the  period,  less  administrative  and  selling  expenses
associated with the sales revenue allocated to us. The commercial launch of Lumoxiti in the U.S. occurred in November 2018 (although revenue derived
from such sales was recognized over a 12 month period in 2019) and is in its ramp-up phase.

Financial income (loss), net

Net financial result increased by €8.7 million, to a €6.3 million gain for the year ended December 31, 2019, as compared to €2.4 million loss for the year
ended  December  31,  2018. This  increase  is  mainly  due  to  a  €4.1  million  gain  relating  to  the  change  in  valuation  allowance  on  financial  instruments  (as
compared to a €3.9 million loss for the year ended December 31, 2018).

For the years ended December 31, 2018 and 2019, the foreign exchange gains and losses mainly result from the variance of the exchange rate between the
Euro and the U.S. dollar on U.S. dollar-denominated cash and cash equivalents and financial assets.

Unrealized gains and losses on financial assets relate to unquoted instruments.

Proceeds related to monalizumab. Revenue related to monalizumab increased by €29.2 million, or 90.3%, to €61.5 million for the year ended December 31,
2018, as compared to €32.3 million for the year ended December 31, 2017. This change is primarily due to (i) the exercise of the option by AstraZeneca in
October 2018, which resulted in revenue of €32.0 million in the year ended December 31, 2018 and (ii) an increase of €18.3 million in revenue recognized in
the period based on the percentage of completion of development work, partially offset by (iii) the impact of the adoption of IFRS 15, which had a negative
impact of €21.0 million on revenue for the year ended December 31, 2018. As of December 31, 2018, the deferred revenue related to monalizumab is €104.9
million (€54.2 million as “Deferred revenue—Current portion” and €50.7 million as “Deferred revenue—Non-current portion”).

Proceeds related to IPH5201.  Revenue  related  to  IPH5201  for  the  year  ended  December  31,  2018  was  €15.6  million  compared  to  nil  for  the  year  ended
December  31,  2017.  Revenue  related  to  the  partial  recognition  of  the  $50.0  million  non-refundable  upfront  payment  received  from  AstraZeneca  in  2018,
which  has  been  recognized  as  revenue  based  on  the  percentage  of  completion  of  the  development  work.  As  of  December  31,  2018,  the  amount  not  yet
recognized in revenue amounted to €27.9 million, classified as “Deferred revenue—Current portion.”

Invoicing of research and development costs. Revenue from invoicing of research and development costs for the year ended December 31, 2018 was €2.2
million compared to nil for the year ended December 31, 2017. Pursuant to our agreements with AstraZeneca, research and development costs related to
avdoralimab  are  equally  shared  between  us  and  AstraZeneca  and  research  and  development  costs  related  to  IPH5201  are  fully  borne  by  AstraZeneca,
resulting in periodic settlement invoices.

Government financing for research expenditures

Government financing for research expenditures increased by €2.7 million, or 23.3%, to €14.1 million for the year ended December 31, 2018, as compared to
€11.4  million  for  the  year  ended  December  31,  2017.  This  change  is  primarily  a  result  of  an  increase  in  the  research  tax  credit  of  €2.5  million,  which  is
mainly  due  to  an  increase  in  eligible  research  and  development  personnel  expenses  and  an  increase  in  amortization  of  the  monalizumab  intangible  asset
following the additional consideration due to Novo Nordisk A/S in 2018. The table below details government funding for research expenditures for the years
ended December 31, 2017 and 2018.

  As a result of the adoption of IFRS 15 as of January 1, 2018, monalizumab expenses do not include our co-funding share of research and development work performed by AstraZeneca,
which  amounted  to  €15.5  million  and  is  recorded  as  a  reduction  to  the  transaction  price,  which  is  to  be  recorded  as  a  revenue  based  on  the  percentage  of  completion.  See  the  table
appearing on Section 2.d of this Annual Report for reconciliation to IFRS 15.

  Lumoxiti research and development expenses mainly relate to the generation of additional data for regulatory purposes.

Research  and  development  increased  by  €2.6  million,  or  3.8%,  to  €69.6  million  for  the  year  ended  December  31,  2018,  as  compared  to  research  and
development of €67.0 million for the year ended December 31, 2017. The increase is mainly explained by: (i) an increase of €9.6 million in expenses related
to avdoralimab following our acquisition of the related rights from Novo Nordisk in June 2017, (ii) an increase of €8.3 million in expenses related to the
progress of our monalizumab program (excluding the IFRS 15 impact), partially offset by (iii) a decrease of €15.5 million related to the impact of IFRS 15.

Personnel expenses including share-based compensation to our employees and consultants decreased by €0.5 million, or 3.2%, to €14.2 million for the year
ended December 31, 2018, as compared to €14.7 million for the year ended December 31, 2017. This decrease is the cumulative impact of (i) the decrease of
€3.0 million in share-based payments partially offset by (ii) the increase in wages and salaries of €2.5 million due to increases in employee headcount and
bonuses paid. As of December 31, 2017 and 2018, we had 147 and 154 employees engaged in research and development activities, respectively.

Selling, general and administrative expenses

Selling, general and administrative expenses increased by €1.1 million, or 6.6%, to €18.1 million for the year ended December 31, 2018, as compared to
€17.0  million  for  the  year  ended  December  31,  2017.  Selling,  general  and  administrative  expenses  represented  a  total  of  20.3%  and  20.7%  of  the  total
operating expenses for the years ended December 31, 2017 and 2018, respectively.

  Other expenses are related to intellectual property, maintenance costs for laboratory equipment and our headquarters, depreciation and amortization and other selling, general and

administrative expenses.

Personnel expenses includes the compensation paid to our employees and consultants, and decreased by €2.9 million, or 27.3%, to €7.6 million for the year
ended December 31, 2018, as compared to personnel expenses of €10.5 million for the year ended December 31, 2017. This decrease results from a decrease
in  share-based  payments  of  €4.3  million,  partially  offset  by  the  increase  in  wages  and  salaries  of  €1.4  million.  As  of  December  31,  2017,  we  had  41
employees in general and administrative functions, which was stable compared to December 31, 2018.

Non-scientific  advisory  and  consulting  expenses  mostly  consist  of  auditing,  accounting,  taxation  and  legal  fees  as  well  as  consulting  fees  in  relation  to
business strategy and operations and hiring services. Non-scientific advisory and consulting expenses increased by €1.5 million, or 39.7%, to €5.3 million for
the  year  ended  December  31,  2018  as  compared  to  €3.8  million  for  the  year  ended  December  31,  2017,  primarily  as  a  result  of  our  agreement  with
AstraZeneca entered into in October 2018.

Net income (loss) from distribution agreements

We recognized a net loss of €1.1 million from the Lumoxiti distribution agreement in the year ended December 31, 2018, which reflected immaterial revenue
from sales of Lumoxiti in the period, less administrative and selling expenses associated with the sales revenue allocated to us.

Financial income (loss), net

Net financial loss decreased by €5.6 million, or 69.8%, to €2.4 million for the year ended December 31, 2018, as compared to €8.0 million for the year ended
December 31, 2017.

For the years ended December 31, 2017 and 2018, the foreign exchange gains and losses mainly result from the variance of the exchange rate between the
Euro and the U.S. dollar on U.S. dollar-denominated cash and cash equivalents and financial assets.

Unrealized losses on financial assets relate to unquoted instruments.

Critical Accounting Policies and Significant Judgments and Estimates

Our consolidated financial statements are prepared in accordance with IFRS. Some of the accounting methods and policies used in preparing the financial
statements  under  IFRS  are  based  on  complex  and  subjective  assessments  by  our  management  or  on  estimates  based  on  past  experience  and  assumptions
deemed  realistic  and  reasonable  based  on  the  facts  and  circumstances.  The  actual  value  of  our  assets,  liabilities  and  shareholders’  equity  as  well  as  our
income and expenses could differ from the value derived from these estimates if conditions changed and these changes had an impact on the assumptions
adopted. See Note 2 to our consolidated financial statements appearing elsewhere in this Annual Report.

We believe that the most significant management judgments and assumptions in the preparation of our consolidated financial statements are described below.

Accounting for collaboration and licensing arrangements

To  date,  our  revenue  has  been  generated  primarily  from  payments  received  in  relation  to  research,  collaboration  and  licensing  agreements  signed  with
pharmaceutical  companies.  These  contracts  generally  provide  for  components  such  as  upfront  payments,  milestone  payments  upon  reaching  certain
predetermined development objectives, research and development funding, as well as payment of royalties on future sales of products.

Non-refundable upfront payments are deferred and recognized as revenue over the period we are engaged to deliver services to the third-party. Revenue is
recognized based on completion of the underlying work.

Milestone  payments  represent  amounts  received  from  our  collaborators,  the  receipt  of  which  is  dependent  upon  the  achievement  of  certain  scientific,
regulatory,  or  commercial  milestones.  We  recognize  milestone  payments  when  the  triggering  event  has  occurred,  there  are  no  further  contingencies  or
services to be provided with respect to that event, and the counterparty has no right to refund of the payment. The triggering event may be scientific results
achieved by us or another party to the arrangement, regulatory approvals, or the marketing of products developed under the arrangement.

Measurement of the subcontracting costs relating to clinical trial costs

Our expense accruals for clinical trials are based on estimates of the fees associated with services provided by clinical trial investigational sites and clinical
research organizations. Payments under some of the contracts we have with such parties depend on factors such as successful enrollment of patients, site
initiation and the completion of clinical trial milestones. In accruing service fees, we estimate the time period over which services will be performed and the
level of effort to be expended in each period. If possible, we obtain information regarding unbilled services directly from these service providers. However,
we may be required to estimate these services based on other information available to us. If we underestimate or overestimate the activity or fees associated
with  a  study  or  service  at  a  given  point  in  time,  adjustments  to  research  and  development  expenses  may  be  necessary  in  future  periods.  Historically,  our
estimated accrued expenses have approximated actual expense incurred. However, due to the nature of such estimates, we cannot assure you that we will not
make changes to our estimates in the future as we become aware of additional information about the status or conduct of our clinical trials and other research
activities.

178

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Measurement of AstraZeneca invoices under the monalizumab and Lumoxiti agreements

The quarterly invoices submitted under these agreements are based on estimates made by AstraZeneca on the basis of its accounting work, which requires
AstraZeneca  to  make  estimates  regarding  the  advancement  of  clinical  programs  and  associated  costs.  AstraZeneca  provides  us  with  an  update  on  their
budgets,  which  provides  us  with  visibility  into  variations  and  allows  us  to  identify  potential  deviations.  These  invoices  have  a  significant  impact  on  our
operating expenses and trade payables.

Measurement of the fair value of free shares

Since January 1, 2018, we have granted share-based compensation under several plans to certain employees and members of our executive and supervisory
boards in the form of free shares (Attributions gratuites d’actions,  or  AGA),  free  preferred  shares  convertible  into  ordinary  shares  (Attributions  gratuites
d’actions de préférence convertibles en actions ordinaires, or AGAP) and free performance shares (Attributions gratuites d’actions de performance, or AGA
Perf) as follows:

We  account  for  share-based  compensation  in  accordance  with  the  authoritative  guidance  on  share-based  compensation,  IFRS  2  Share-based payment,  or
IFRS 2. Pursuant to IFRS 2, the awards are measured at their fair value on the date of grant. The fair value is calculated with the most relevant formula
regarding the conditions and the settlement of each plan.

Determining the fair value of share-based awards at the grant date requires judgment. We use the Black-Scholes option and Monte Carlo approach pricing
models to determine the fair value of share-based compensation. Free preference shares plans includes performance conditions that are based on the market
price of our ordinary shares. Holders of free preference shares may also benefit from accelerated vesting triggered by the achievement of internal goals.

The determination of the grant date fair value of warrants and free shares is affected by assumptions regarding a number of complex and subjective variables.
These variables include the fair value of our ordinary shares on the date of grant, the expected term of the awards, our share price volatility, the employee
turnover weighted average probability, risk-free interest rates, expected dividends, and performance conditions when applicable. We estimate these items as
follows:

Fair value of our ordinary shares. As our ordinary shares are publicly traded on Euronext Paris, for purposes of determining the fair value of our ordinary
shares  we  have  established  a  policy  of  using  the  closing  sales  price  per  ordinary  share  as  quoted  on  Euronext  Paris  on  the  date  of  the  grant  by  the
management board.

Expected Volatility. We use the historical volatility of our ordinary shares on Euronext Paris, made on the basis of a Capital Asset Pricing model of the share
price using a Monte Carlo approach.

Employee turnover weighted average probability. This rate is based on the historical data from our company.

Risk-Free Interest Rate. The risk-free interest rate is based on the Euribor swap.

Dividend Yield. We have never declared or paid any cash dividends and do not presently plan to pay cash dividends in the foreseeable future. Consequently,
we have used an expected dividend yield of zero.

If any of the assumptions used in the Black-Scholes and Monte-Carlo models change significantly, share-based compensation for future awards may differ
materially compared to the awards granted previously.

Measurement of employee-benefit obligations

The amount of defined benefit obligation is measured according to actuarial valuations. Inherent in these valuations are key actuarial assumptions such as the
discount  rate,  mortality  tables  and  rates  of  turnover  in  employee  personnel.  These  assumptions  are  provided  in  Note  10  to  our  consolidated  financial
statements  appearing  elsewhere  in  this  Annual  Report.  Any  change  in  these  actuarial  assumptions  could  have  a  significant  impact  on  our  consolidated
financial statements.

Measurement of contingencies and loss provision

As part of our activities, we may be exposed to contractual commitment risk. Management exercises its judgment to estimate the probability and amount of
cash outflows, as well as the information to disclose regarding contingent liabilities.

180

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Estimate of the recoverable amount of the acquired and under progress licenses

Impairment tests are performed on a yearly basis for the intangible assets which are not amortized (such as intangible assets in progress). We test amortizable
intangible assets for impairment when there is an indicator of impairment. Impairment tests involve comparing the recoverable amount of the licenses to their
net book value. The recoverable amount of an asset is the higher of its fair value less costs to sell and its value in use. If the carrying amount of any asset is
above its recoverable amount, we recognize an impairment loss to reduce the carrying amount to the recoverable amount. The main assumptions used for the
impairment  test  include  (a)  the  amount  of  cash  flows  that  are  set  on  the  basis  of  the  development  and  commercialization  plans  and  budgets  approved  by
Management, (b) assumptions related to the achievement of the clinical trials and the launch of the commercialization, (c) the discount rate, (d) assumptions
on  risk  related  to  the  development  and  (e)  for  the  commercialization,  selling  price  and  volume  of  sales,  and  are  provided  in  Note  6  to  our  consolidated
financial statements which are included elsewhere in this Annual Report. Any change in these assumptions could lead to the recognition of an impairment
charge that could have a significant impact on our consolidated financial statements.

In case of failure of the clinical trials in progress, we may have to fully depreciate the intangible asset.

Estimate of the useful life of the acquired licenses

Intangible assets are amortized on a straight line basis over their anticipated useful life. The estimated useful life is the period over which the asset provides
future  economic  benefits.  It  is  estimated  by  management  and  is  regularly  revised  by  taking  into  consideration  the  period  of  development  over  which  it
expects to receive economic benefits such as collaboration revenues, royalties and product of sales. However, given the uncertainty surrounding the duration
of the research and development activities for the programs in development and their likelihood to generate future economic benefits to the company, the
estimated useful life of the rights related to these programs is rarely longer than the actual development phase of the product candidate. When a program is in
commercialization phases, the useful life takes into account the protection of the exclusivity rights and the anticipated period of commercialization without
taking into account any extension or additional patents.

B.       Liquidity and Capital Resources.

The liquidity and capital resources discussion that follows contains certain estimates as of the date of this Annual Report of our estimated future sources and
uses  of  liquidity  (including  estimated  future  capital  resources  and  capital  expenditures)  and  future  financial  and  operating  results.  These  estimates  reflect
numerous assumptions made by us with respect to industry performance, general business, economic, regulatory, market and financial conditions and other
future events, and matters specific to our businesses, all of which are difficult or impossible to predict and many of which are beyond our control.

Sources and uses of liquidity

We  have  primarily  financed  our  operations  through  our  receipt  of  $475.0  million  (€415.9  million)  in  payments  from  our  collaborators,  including
AstraZeneca, since 2011, excluding payments received for purchases of our equity securities by our collaborators.

181

 
 
 
 
 
 
 
 
 
 
 
 
 
We have also financed our operations since our inception through several rounds of public and private financings. Since our inception, we have raised a total
of €306.4 million through the sale of equity securities, including €33.7 million in the initial public offering of our ordinary shares on Euronext Paris in 2006
and €66.0 million in the initial public offering of our initial public offering of our ordinary shares on Nasdaq New-York in 2019.

In addition, we have received an aggregate of €80.6 million in research tax credits through December 31, 3019. As a French biopharmaceutical company, we
have benefited from certain tax advantages, including, for example, the research tax credit. The research tax credit can be offset against French corporate
income tax due and the portion in excess, if any, may be refunded. The research tax credit is calculated based on our claimed amount of eligible research and
development expenditures in France. The research tax credit increased by €3.2 million, or 23,7 %, to €16.7 million for the year ended December 31, 2019, as
compared to a research tax credit of €13.5 million for the year ended December 31, 2018.

Until December 31, 2018, we qualified as a small or medium size business. Therefore, the French Treasury refunded our 2017 and 2018 research tax credit
claims during 2018 and 2019, respectively, and we received reimbursement of the 2018 research tax credit in compliance with the applicable regulatory rules
in July 2019. We lost our status as a small or medium size business at the end of the year ended December 31, 2019 and, therefore, we will no longer be
entitled to the immediate reimbursement of the Research Tax Credit but instead will be reimbursed within the expiry of a three-year period.

We are potentially eligible to earn a significant amount of milestone payments and royalties under our agreements with AstraZeneca in the event that we
satisfy certain pre-specified milestones. We may enter into new collaboration agreements that also provide milestone payments. These milestone payments
are  dependent  on  the  accomplishment  of  various  development,  regulatory  and  commercialization  objectives,  and  the  achievement  of  many  of  these
milestones  is  outside  of  our  control.  However,  our  ability  to  earn  these  payments  and  their  timing  will,  in  part,  be  dependent  upon  the  outcome  of  our
research activities which is uncertain at this time.

On July 3, 2017, we borrowed from the bank Société Générale in order to finance the construction of our future headquarters. This loan, amounting to a
maximum of €15.2 million, can be drawn down during the period of the construction in order to pay supplier payments as they become due, but in any event
no later than August 30, 2019. We have decided to postpone this construction. Until this construction begins, the proceeds of the loan will be used to finance
several  projects,  such  as  extension  of  our  current  building,  improvement  of  our  information  systems  and  development  of  our  commercial  infrastructure.
Repayment of any amounts drawn down are payable over a 12-year term beginning on August 30, 2019 and ending on August 30, 2031. As security for the
loan, we pledged collateral in the form of financial instruments held at Société Générale amounting to €15.2 million. The security interest on the pledged
financial instruments will be released in accordance with the following schedule: €4.2 million in July 2024, €5.0 million in July 2027 and €6.0 million in July
2031. We had drawn down €15.2 million under the loan as of December 31, 2019. The loan bears a fixed interest rate of 2.01%. Under the loan, we are
subject to a covenant that our total cash, cash equivalents and current and non-current financial assets as of each fiscal year end will be at least equal to the
amount of outstanding principal under the loan. The repayment period started on August 30, 2019.

182

 
 
 
 
 
 
 
 
 
We lease our headquarters in Luminy, Marseille, France under a finance lease agreement. The present value of the minimum lease payments until June 2020,
which is the term of the lease, is recognized as a financial liability of €0.2 million as of December 31, 2019. In addition, we obtained a €1.5 million PTZI
loan (Prêt à Taux Zéro Innovation—interest-free loan for innovation) from Banque Publique d’Investissement, or BPI France, in 2013. The loan is repayable
beginning in September 2016 over five years and amounted to €0.5 million as of December 31, 2019. Lastly, during the years ended December 31, 2016 and
2017, we also used lease-financing and bank loans to finance the acquisition of laboratory equipment and to set up new laboratories. The debt related to these
loans amounts to €1.1 million at December 31, 2019.

Cash, cash equivalents and short-term investments increased by €51.3 million, or 30,6 %, to €218.9 million as of December 31, 2019, as compared to cash,
cash equivalents and short-term investments of €167.5 million at December 31, 2018. The cash assets that we hold consist of current accounts and fixed term
accounts. Short-term investments primarily consist of shares of money market funds and mutual funds. Their purpose is to finance our activities, including
our research and development costs.

We have received a total of €306.4 million from capital increases, before deducting the costs associated with capital increases, and after excluding proceeds
from  share  compensation  instruments,  between  1999  and  December  31,  2019.  The  table  below  summarizes  the  main  capital  increases  between  1999  and
December 31, 2019.

Our net cash flow from operating activities increased by €67.5 million to €34.9 million for the year ended December 31, 2019 as compared to net cash flows
used in operating activities of €32.5 million for the year ended December 31, 2018. This improvement of our operating cash flows mainly results from the
collection of €108.7 million of proceeds relating to the agreements signed with AstraZeneca in October 2018, partially offset by an increase of outflows in
relation to our research and development activities.

Cash flows from / (used in) investing activities

Our  net  cash  flows  used  in  investing  activities  for  the  year  ended  December  31,  2019  were  €62.1  million  and  mainly  consisted  of  the  upfront  payment
relating  to  the  acquisition  of  Lumoxiti  (€43.8  million)  and  the  additional  considerations  relating  to  monalizumab  (€13.1  million)  and  anti-CD39  (€7.0
million).

Our net cash flows from investing activities for the year ended December 31, 2018 were €24.3 million and mainly consisted of (i) disposal of net financial
assets for €24.2 million, (ii) interest received on financial assets for €1.4 million, less (iii) acquisitions of property and equipment for €0.9 million and (iv)
acquisition of intangible assets for €0.6 million.

Cash flows from / (used in) financing activities

Our net cash flows from financing activities for the year ended December 31, 2019 increased by €16.6 million to €77.8 million as compared to net cash flows
from financing activities of €61.2 million for the year ended December 31, 2018 This increase mainly results from (i) the net proceeds of our initial public
offering on the Nasdaq in October 2019 (€66.0 million), and (ii) the net proceeds from the drawdown of our borrowings, less repayments during the period
(€11.9 million).

Our net cash flow used in operations decreased by €15.5 million to €32.5 million for the year ended December 31, 2018 as compared net cash flows used in
operations of €48.1 million for the year ended December 31, 2017. This improvement of our operating cash flows results from the collection of €40.3 million
of proceeds relating to the agreements signed with AstraZeneca in October 2018, partially offset by an increase of outflows in relation to our research and
development activities.

Cash flows from / (used in) investing activities

Our net cash flows from investing activities for the year ended December 31, 2018 were €24.3 million and mainly consisted of (i) disposal of net financial
assets for €24.2 million, (ii) interest received on financial assets for €1.4 million, less (iii) acquisitions of property and equipment for €0.9 million and (iv)
acquisition of intangible assets for €0.6 million.

Our  net  cash  flows  used  in  investing  activities  for  the  year  ended  December  31,  2017  were  €29.5  million  and  mainly  consisted  of  (i)  acquisitions  of  net
financial assets for €25.7 million, (ii) the avdoralimab acquired rights from Novo Nordisk A/S resulting in a cash out flows of €2.8 million, as the remaining
part of the upfront payment of €40.0 million was contributed in kind through a capital increase of €37.2 million, (iii) acquisitions of property and equipment
for  €3.0  million  (mainly  related  to  the  acquisition  of  the  land  attached  to  our  headquarters  and  certain  pieces  of  laboratory  equipment),  less  (iv)  interest
received on financial assets for €1.4 million.

The acquisitions of current financial assets consist of purchases of current marketable securities that do not meet the conditions under IAS 7 Statement of
cash  flows  to  be  considered  as  cash  equivalents.  See  Note  4  to  our  consolidated  financial  statements  for  the  year  ended  December  31,  2018  appearing

Cash flows from / (used in) financing activities

Our net cash flows from financing activities for the year ended December 31, 2018 increased by €60.3 million to €61.2 million as compared to net cash flows
from financing activities of €0.9 million for the year ended December 31, 2017. On October 22, 2018, AstraZeneca acquired 9.8% of our capital through the
issuance of 6,260,500 new shares at €10 per share, generating a €62.6 million cash inflow.

Funding requirements

We believe that our existing cash, cash equivalents, short-term investments and non-current financial assets, will enable us to fund our operations for the next
twelve months. We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently
expect.

Until  we  can  generate  a  sufficient  amount  of  revenue  from  sale  of  approved  products,  if  ever,  we  expect  to  finance  our  operating  activities  through  our
existing liquidity and expected milestone payments from collaborators.

Our present and future funding requirements will depend on many factors, including, among other things:

·

·

·

·

·

·

·

·

the size, progress, timing and completion of our clinical trials and preclinical studies for any current or future product candidates, including our lead
product candidates, monalizumab, lacutamab and avdoralimab;

the number of potential new product candidates we identify and decide to develop;

costs associated with our payment obligations to third parties in connection with our development and potential commercialization of certain of our
product candidates;

costs associated with expanding our organization;

the  costs  involved  in  filing  patent  applications  and  maintaining  and  enforcing  patents  or  defending  against  claims  of  infringement  raised  by  third
parties;

the  time  and  costs  involved  in  obtaining  regulatory  approval  for  our  product  candidates  and  any  delays  we  may  encounter  as  a  result  of  evolving
regulatory requirements or adverse results with respect to any of these product candidates;

selling and marketing activities undertaken in connection with the commercialization of Lumoxiti and any other current or future product candidates,
including monalizumab, lacutamab, avdoralimab and IPH5201 and other product candidates, together with the costs involved in the creation of a sales
and marketing organization; and

the amount of revenues, if any, we may derive either directly, or in the form of milestone or royalty payments from any future potential partnership
agreements, from monalizumab, IPH5201, or relating to our other product candidates.

186

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
For more information as to the risks associated with our future funding needs, see “Risk Factors—We may need to raise additional funding to complete the
development  and  any  commercialization  of  our  product  candidates,  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 or other operations.”

Capital expenditures

Our operations mainly require investment in intangible assets. We acquired the rights of avdoralimab from Novo Nordisk A/S in 2017. We paid an upfront of
€40.0 million, of which €37.2 million was contributed in new ordinary shares and €2.8 million in cash.

In January 2019, we paid to AstraZeneca an initial payment for the license related to Lumoxiti ($50.0 million, or €43.8 million, using the foreign exchange
rate of 1.1422 at the date of payment), and in February 2019, we paid to Novo Nordisk A/S additional consideration relating to monalizumab ($15.0 million,
or €13.1 million using the exchange of 1.1394 at the date of payment). In June 2019, we paid €7.0 million to Orega Biotech in relation to the anti-CD39
program as consideration following the collaboration and option agreement signed on October 22, 2018 with AstraZeneca regarding IPH5201.

Our operations generally require little investment in tangible assets because we outsource most of the manufacturing and research activities to third parties.
We  lease  some  of  our  computer  equipment  under  operating  lease  agreements.  We  account  for  our  payments  for  these  items  as  operating  expenses  in  the
consolidated statement of income.

Our capital expenditures in the years ended December 31, 2017, 2018 and 2019 primarily related to laboratory equipment. Clinical research and development
costs are not capitalized until marketing authorizations are obtained.

Our corporate office in Luminy, Marseille, France is leased under a finance lease agreement signed in 2008 with Sogebail, a subsidiary of Société Générale,
for an aggregate of €6.6 million. The lease-financing agreement has a 12-year term. We have a purchase option for all of the buildings and land for the lump
sum of €1 at the end of the term of the contract on June 9, 2020, which we have exercised.

Since July 2017, we also rent office space in Marseille, France under a commercial lease.

C.       Research and Development.

For a discussion of our research and development activities, see “Item 4.B—Business Overview” and “Item 5.A—Operating Results.”

D.       Trend Information.

An outbreak of a novel strain of coronavirus (i.e. COVID-19), which first emerged in the PRC in late December 2019, has since spread to other parts of the
world, including the U.S. and Europe, where we have planned or ongoing clinical trials. We could experience or continue to experience disruptions relating
to this pandemic that could severely impact our business. The full extent, consequences, and duration of the COVID-19 pandemic and the resulting impact on
our business, financial condition and results of operations cannot be predicted on the date of this Annual Report. We will continue to evaluate the impact that
the COVID-19 pandemic could have on our business, financial condition and results of operations during the year ending December 31, 2020.

187

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
See  “Item  4D.—Risk  Factors—Risks  Related  to  the  Development  and  Commercialization  of  Lumoxiti  and  Our  Product  Candidates—The  recent  global
COVID-19 pandemic could adversely affect our business, financial condition and results of operations.”

E.       Off-Balance Sheet Arrangements.

During the periods presented, we did not, and we do not currently, engage in off-balance sheet financing arrangements as defined under SEC rules, such as
relationships  with  other  entities  or  financial  partnerships,  which  are  often  referred  to  as  structured  finance  or  special  purpose  entities,  established  for  the
purpose of facilitating financing transactions that are not required to be reflected on our consolidated statement of financial position. In addition, we do not
engage  in  trading  activities  involving  non-exchange  traded  contracts.  We  therefore  believe  that  we  are  not  materially  exposed  to  any  financing,  liquidity,
market or credit risk that could arise if we did engage in these relationships.

  Lease finance obligations—real estate relate primarily to real estate property in relation to our acquisition of our headquarters and main laboratories.
  We paid a guarantee to Sogebail for our real estate lease in the form of a down payment. This down payment amounted to €0.1 million as of December 31, 2019.
  On January 10, 2020, the Company signed an amendment to its lease in order to expand its premises (“Le Virage”). This amendment also extends the duration of the contractual

commitment. The effective date of this amendment is January 15, 2020. The figures presented do not include the payments relating to this amendment.

The  commitment  amounts  in  the  table  above  are  associated  with  contracts  that  are  enforceable  and  legally  binding  and  that  specify  all  significant  terms,
including fixed or minimum services to be used, fixed, minimum or variable price provisions, and the approximate timing of the actions under the contracts.
The table does not include obligations under agreements that we can cancel without a significant penalty as well as obligations under our employment benefit
plans, which amounted to €3.8 million as of December 31, 2019.

As of December 31, 2019, we have non-cancellable purchase commitments for a total of €0.2 million with various CMOs.

As part of a supply of scientific equipment, we were committed towards a supplier to minimum annual purchases of consumables. As of December 31, 2019,
the overall commitment amounted to €0.1 million for the period from January to June 2020.

In addition, we have certain obligations under the terms of research, collaboration and licensing agreements which usually require us to bear all expenses
relating  to  the  procurement,  examination  and  extension  procedures  of  patents,  as  well  as  to  uphold  and  defend  the  patents  and  will  require,  according  to
certain milestones, the payment of lump sums and royalties on sales to the licensor. The timing of the obligations depends on when related milestones are
reached, which cannot be anticipated.

189

 
 
 
 
 
 
 
   
   
   
   
   
   
   
   
   
   
 
 
 
 
 
 
 
 
We also signed option agreements which require us to (i) bear all expenses relating to the procurement, examination and extension procedures of patents, as
well as to uphold and defend the patents, (ii) pay a lump sum of money as option payment and (iii) if we decide to later opt-in, to pay to the licensor of lump
sums (milestone payments) and royalties on sales.

Lastly, we signed certain agreements with collaborators, which defined the rules of joint-ownership and the granting of rights regarding certain aspects of
intellectual property. Under these contracts, we usually bear all expenses relating to the procurement, examination and extension procedures of the patents
and to any procedure required to uphold and defend the patents. These agreements also usually require, in exchange for a license over the share of rights
owned by the co-owner, and according to certain milestones, the payment of lump sums and royalties on sales to the co-owner. For example, we may be
obligated  to  pay  Novo  Nordisk  A/S  up  to  €20.0  million  in  potential  regulatory  milestones  relating  to  monalizumab  and  tiered  mid-to-high  single-digit
percentage royalties on net sales of monalizumab products, and up to an aggregate of €370.0 million upon the achievement of development, regulatory and
sales milestones relating to avdoralimab and tiered royalties ranging from a low double-digit to low-teen percentage of net sales of avdoralimab. We may
also be obligated to pay Orega Biotech up to an additional €51.5 million in the aggregate upon the achievement of development and regulatory milestones,
and  mid-single  digit  to  low-teen  percentage  payments,  depending  on  determinations  relating  to  Orega  Biotech’s  intellectual  property  rights  for  certain
patents, on sublicensing revenues we receive pursuant to our agreement with AstraZeneca relating to IPH5201. Finally, in January 2020, we made a $15.0
million  milestone  payment  as  a  result  of  the  achievement  of  a  regulatory  milestone  relating  Lumoxiti.  We  are  also  obligated  to  pay  a  low  single  digit
percentage royalties on our net sales of Lumoxiti, and are obligated to pay Selexis SA, for each of lacutamab, IPH5201 and IPH5301, up to 1.6 million Swiss
francs in development and regulatory milestones and either up to 50.0 million Swiss francs in commercial milestones or low single digit percentage royalties
on net sales.

Limitations on Liability and Indemnification Matters

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

We have liability insurance for our Executive and Supervisory Board members, and insurance coverage for liability under the Securities Act. We also entered
into  agreements  with  our  Executive  and  Supervisory  Board  members  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, fines and settlement amounts incurred by any of these individuals in any action or proceeding arising out of his or her actions in
that capacity. We believe that this insurance and these agreements are necessary to attract qualified Executive and Supervisory Board members.

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

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  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 Executive Board and Supervisory Board members,
employees and consultants, including (i) BSAs, which have historically only been granted to independent members of the Supervisory Board and consultants,
(ii) BSAARs and (iii) free shares.

Our Executive Board’s authority to grant these warrants and free shares and the aggregate amount authorized to be granted must be approved by two-thirds of
the shareholders present at the relevant extraordinary shareholders’ meeting. Once approved by our shareholders, our Executive Board can continue to grant
such awards for a specified period upon prior authorization of the Supervisory Board.

We have various compensation plans for our Executive Board members, Supervisory Board members, employees and consultants that have been approved by
our shareholders. The last allocation in 2015 of BSAARs no longer continue to vest following termination of the employment, office or service of the holder
within the first two years and all vested warrants 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 ordinary shares issuable and/or the exercise price of the outstanding warrants.

Equity Warrants and Redeemable Share Subscription Warrants

Share Warrants (BSA)

Share warrants, or BSA, are granted at a de minimis price and entitle the holder of one BSA to exercise the warrant for one underlying share, at an exercise
price per share determined by our Executive Board at the time of grant by reference to the then prevailing share price. We have granted BSA to Supervisory
Board  members  and  certain  consultants  of  the  Company.  Our  share  warrants  plans  include  provisions  that  allow  for  the  adjustment  of  the  one-for-one
exercise ratio to compensate for certain modifications of our share capital, such as rights issues, stock splits, mergers and other events affecting all existing
shareholders.  None  of  those  events  have  occurred  yet.  Our  BSA  have  an  exercise  period  of  10  years  –  BSA  not  exercised  after  that  time  lapse  and  are
automatically cancelled. Our share warrants cannot be sold.

Redeemable Share Warrants (BSAAR)

Redeemable  share  warrants,  or  BSAAR,  are  identical  to  our  share  warrants  of  BSA  (including  the  one-for-one  exercise  ratio,  its  potential  adjustment  for
certain modifications of our share capital and the exercise period of 10 years), except for the following features:

·

·

the BSAAR are initially purchased by the beneficiary at their fair value, as determined by an expert, and

the BSAAR plans include a “forcing” clause making it possible to encourage holders to exercise their BSAAR when the market price exceeds the
exercise price and reaches a threshold defined in the BSAAR plan. We can then, subject to a time period for notifying the holders that will permit
them to exercise their BSAAR, decide to purchase the unexercised BSAAR at a unit price equal to the BSAAR acquisition price initially paid by its
holder.

Our redeemable share warrants cannot be sold. Our BSAAR have been granted to certain of our executive officers and employees.

Free Shares (AGA)

Free  shares,  or  AGA,  are  employee  equity  incentive  instruments  pursuant  to  which  the  beneficiaries  are  granted,  for  free,  the  possibility  to  receive  our
ordinary shares under certain conditions. Upon grant by our Executive Board, the AGA are subject to an acquisition, or vesting, period of at least one year.
At the end of this period, the free shares vest and the beneficiary becomes a full shareholder. However, if the vesting period is less than a certain period set by
law of currently two years (but three years under previous law), it must be followed by a lock-up period, so that the sum of the two periods is equal to a
minimum total period also set by law of currently two years (but three years under previous law). Vesting can be conditional or not. The vesting of all or our
AGA is subject to a presence condition at the end of the vesting period. Some of our AGA are also subject to performance conditions. Over the years, we
have established several AGA plans, for our employees or for management only, sometimes as a “welcome package” (with no performance conditions). Our
free share plans include provisions that allow for the adjustment of the number of ordinary shares to which a beneficiary is entitled at the end of the vesting
period  to  compensate  for  certain  modifications  of  our  share  capital,  such  as  rights  issues,  stock  splits,  mergers  and  other  events  affecting  all  existing
shareholders, during the vesting period. Certain of our plans also provide for an accelerated vesting in case of a tender offer on the Company during the
vesting period.

One particular AGA plan, the “AGA Bonus,” entitles our management to opt for the payment of up to 50% of their annual variable compensation in free
shares. Those who take this option benefit from a matching compensation equal to 30% of the corresponding portion of the annual variable compensation,
also  payable  in  free  shares.  The  AGA  Bonus  are  subject  to  the  same  performance  conditions,  after  a  one-year  vesting  period,  as  the  annual  variable
compensation. The number of AGA Bonus is determined by dividing the euro amount of the annual variable compensation for which the election is made
and of the matching contribution, by an average of the trading price of our shares. Once vested, the AGA Bonus are subject to the minimum one-year lock-up
period.

  The annual variable compensation performance conditions are determined on or about the beginning of the fiscal year and executives make their election at about that time. However,
because we need the shareholders’ vote on the total number of free shares available for granting AGA Bonus (like all other free shares), we wait until our annual shareholders meeting
(generally during the second half of the second quarter of the year) to grant the AGA Bonus – hence a granting, vesting and lock-up calendar different from that of the payment of the
annual variable compensation, which takes place towards the end of the fiscal year or at the beginning of the next fiscal year.

  Usually after the end of the vesting period, the Executive Board will convene and acknowledge the number of free shares that have vested and the number of those that have not because
the presence condition and, as applicable, the performance conditions, have not been met. For the purpose of computing the amount of share-based compensation in our consolidated
financial statements, AGA that have lapsed because the presence condition has not been met, are excluded from the computation, even though the Executive Board has not met yet and
formally acknowledged this fact. As a result, certain of the numbers above are different from those in our consolidated financial statements.

The following authorization will be submitted for approval to the general meeting of the shareholders to be held on May 19, 2020: (i) up to 200,000 free
shares  to  the  benefit  of  employed  members  of  the  Executive  Committee,  employed  senior  executives  and/or  corporate  officers  (AGA  Bonus),  (ii)  up  to
770,000  free  shares  with  performance  conditions  to  the  benefit  of  executive  officers,  employed  members  of  the  Executive  Committee,  employed  senior
executives and/or corporate officers and (iii) up to 910,000 free shares with performance conditions to the benefit of employees.

Free Preferred Shares (AGAP)

Free preferred shares, or AGAP, are another employee equity incentive instrument similar to the free shares or AGA, except that, after a one-year vesting
period,  the  beneficiaries  receive  a  preferred  shares  (shares  B)  which  will  become  convertible  into  ordinary  shares  following  a  lock-up  period  of  two
additional years, if the performance conditions (and a presence condition) are met at the end of this lock-up period. Each free preferred share is convertible
into a number of our ordinary shares – which number depends upon the degree of fulfilment of the performance conditions. The free preferred shares remain
convertible into ordinary shares for a period of six years and six months. Free preferred shares not converted at the end of this conversion period can be
repurchased by us and cancelled. Our AGAP cannot be sold.

We have established several AGAP plans in 2016 and 2017 for all of our employees or for management only.

During  the  acquisition  and  lock-up  periods,  beneficiaries  of  the  2016  AGAP  are  not  entitled  to  vote  at  our  shareholders’  meetings,  to  dividends  or  to
preferential subscription rights. On the contrary, during the lock-up period, beneficiaries of the 2017 AGAP are entitled to vote at our shareholders’ meetings,
to dividends and to preferential subscription rights, as if they held the same number of ordinary shares as their number of vested AGAP. After the end of the
lock-up period, holders of all of our AGAP that have not yet converted them into our ordinary shares, are entitled to vote at our shareholders’ meetings, to
dividends and to preferential subscription rights, on the basis of the number of ordinary shares to which they are entitled if they convert their AGAP.

208

 
 
 
 
 
 
 
 
 
Our  free  preferred  share  plans  include  provisions  that  allow  for  the  adjustment  of  the  number  of  ordinary  shares  to  which  a  beneficiary  is  entitled  upon
conversion of his or her AGAP at the end of the lock-up period, to compensate for certain modifications of our share capital, such as rights issues, stock
splits,  mergers  and  other  events  affecting  all  existing  shareholders.  The  2017  AGAP  plan  provides  for  an  accelerated  vesting  with  a  waiver  of  the
performance conditions in case of a tender offer on the Company during the vesting period.

On October 21, 2019, the performance criteria of the 2016-1 AGAP were assessed and the conversion ratio was determined as follows: one 2016-1 AGAP
gives the right to 130 ordinary shares.

On December 30, 2019, the performance criteria of the 2016-2 AGAP were assessed and the conversion ratio was determined as follows: one 2016-2 AGAP
gives the right to 111 ordinary shares.

The following table shows the AGAPs outstanding as of December 31, 2019:

The Supervisory Board is made up of a minimum of three members and a maximum of eighteen. The members of the Supervisory Board are appointed for a
renewable term of two years at the general meeting of shareholders. The general meeting of shareholders may revoke the appointments of the members of the
Supervisory Board at any time during the meeting by a simple majority vote. The appointees are selected by the shareholders and may be individuals or
companies. Each member must own at least one of our ordinary shares for the entire term of the appointment.

The age limit for being a member of the Supervisory Board and the limitations on holding such an appointment concurrently with an appointment in another
company are subject to the applicable legal and regulatory provisions.

Role of the Supervisory Board in Risk Oversight

Our  Supervisory  Board  is  primarily  responsible  for  the  oversight  of  our  risk  management  activities  and  has  delegated  to  the  audit  committee  the
responsibility  to  assist  our  Supervisory  Board  in  this  task.  While  our  Supervisory  Board  oversees  our  risk  management,  our  management,  through  the
Executive  Board  is  responsible  for  day-to-day  risk  management  processes.  Our  Supervisory  Board  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  Supervisory  Board.  We  believe  this  division  of  responsibilities  is  the  most  effective
approach for addressing the risks we face.

Supervisory Board Committees

The Supervisory Board has established an audit committee, a compensation and nomination committee and a transactions committee, which operate pursuant
to rules of procedure adopted by our Supervisory Board.

Subject  to  available  exemptions,  the  composition  and  functioning  of  all  of  our  committees  will  comply  with  all  applicable  requirements  of  the  French
Commercial Code, the Exchange Act, the Nasdaq listing rules and SEC rules and regulations.

In accordance with French law, committees of our Supervisory Board only have an advisory role and can only make recommendations to our Supervisory
Board.  As  a  result,  decisions  are  made  by  our  Supervisory  Board  taking  into  account  non-binding  recommendations  of  the  relevant  Supervisory  Board
committee.

Audit Committee

Our  audit  committee  assists  our  Supervisory  Board  in  its  oversight  of  our  corporate  accounting  and  financial  reporting  and  oversees  the  selection  of  our
auditors, their remuneration and independence and keeps the Supervisory Board informed on control systems, key processes and procedures, security and
risks. From the Supervisory Board of May 22, 2019, the members of the audit committee as of the date of this Annual Report are Patrick Langlois, Irina
Staatz-Granzer and Mailys Ferrere as representative of Bpifrance Participations. Dr. Langlois is the Chairman of the audit committee.

Our Supervisory Board has determined that Dr. Langlois and Dr. Staatz-Granzer are independent within the meaning of the applicable listing rules and the
independence  requirements  contemplated  by  Rule  10A-3  under  the  Exchange  Act.  Our  Supervisory  Board  has  further  determined  that  Dr.  Langlois  is  an
“audit committee financial expert” as defined by the Nasdaq listing rules and that each of the members qualifies as financially sophisticated under the Nasdaq
listing rules.

The principal responsibility of our audit committee is to monitor the existence and efficacy of our financial audit and risk control procedures on an ongoing
basis.

210

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Our Supervisory Board has specifically assigned the following duties to the audit committee:

·

·

·

·

·

legal control of the half-year and annual accounts;

evaluating internal control practices, risk analysis;

supervising the creation of the financial statements published by us;

assessing accounting methods; and

selecting statutory auditors, negotiating their fees, reviewing of their conclusions and reviewing their independence.

The audit committee reviews and approves the report from the Chairman of the Supervisory Board on internal control.

Compensation and Nomination Committee

Our  compensation  and  nomination  committee  assists  our  Supervisory  Board  in  reviewing  and  making  recommendations  to  our  Supervisory  Board  with
respect  to  the  appointment  and  the  compensation  of  the  members  of  our  Executive  Board,  Supervisory  Board  and  Executive  Committee  and  other  key
employees. In accordance with operating rules adopted by the Supervisory Board, the nomination and compensation committee is composed of at least two
members  appointed  by  the  Supervisory  Board.  Following  the  Supervisory  Board  on  May  22,  2019,  the  members  of  the  committee  are  Patrick  Langlois,
Hervé  Brailly  and  Véronique  Chabernaud.  Currently,  Dr.  Langlois  and  Dr.  Chabernaud  are  independent  members  of  the  compensation  and  nomination
committee. Dr. Chabernaud is the Chairman of the committee.

Our Supervisory Board has specifically assigned the following duties to the compensation and nomination committee: reviewing our remuneration policy, in
particular  the  description  of  our  collective  objectives  (applicable  company-wide)  and  individual  objectives  (for  members  of  the  Executive  Board  and  the
Executive  Committee),  reviewing  the  compensation  of  the  members  of  our  Executive  Board  and  the  Executive  Committee,  the  policy  concerning  the
distribution  of  equity  such  as  warrants,  stock  options,  grants  and  capital  increases  reserved  for  members  of  our  savings  plan,  examining  the  amount  of
attendance fees among the Supervisory Board and the committees members, assisting the Supervisory Board in the selection of the members of the Executive
Board and committees, making recommendations with respect to the independence of the members of the Supervisory Board and committees and preventing
conflicts of interest within the Supervisory Board.

Transactions Committee

Our transactions committee assists our Supervisory Board in examining the business and corporate development opportunities available to us, which may
include the acquisition of rights to products or the acquisition of other companies as well as out-licensing opportunities. The members of this committee are
Irina  Staatz-Granzer,  Hervé  Brailly,  Gilles  Brisson  and  Marcus  Schindler.  Currently,  Dr.  Staatz-Granzer  is  an  independent  member  and  Chairman  of  the
transactions committee. Our Supervisory Board has specifically assigned the following duties to the transactions committee: to analyze the fundamentals of
the  products  and/or  companies  targeted  by  us,  the  feasibility  of  targeted  acquisitions  and  to  participate  in  the  selection  of  investment  bankers  and/or
consultants.

Other Committees

The Strategic Advisory Board

We  also  have  a  Strategic  Advisory  Board  composed  of  six  external  consultants,  consisting  of  three  individuals  from  the  medical  community  and  three
individuals from the scientific community. The Strategic Advisory Board is not a committee of the Supervisory Board within the meaning of Article R.225-
29 of the French Commercial Code; its members are chosen by the Executive Board. This kind of advisory committee is common in French companies in the
biotechnology sector.

The Strategic Advisory Board’s role is to assist us in our strategic choices in scientific and technical fields. Its main missions are to evaluate the relevance of
our choices in terms of product development and to propose, if necessary, changes to strategic or technical approaches; to advise management and guide our
scientific  direction  in  identifying  strategies  and  selecting  product  candidates,  based,  in  particular,  on  the  scientific  results  obtained  by  us,  including  new
targets and new compounds and to promote and advise us in our alliance strategies, such as external growth supporting synergies, including acquisition of
new competences, purchase of operating rights, product candidates and innovative technologies. The Strategic Advisory Board is comprised of Sebastian
Amigorena, Aurélien Marabelle, Ruslan Medzhitov, Miriam Merad, Tanguy Seiwert and Mario Sznol. Dr. Merad is the Chairman of the Strategic Advisory
Board.

Sebastian Amigorena, Ph.D., is the “Directeur de Recherche de Classe Exceptionnelle” at the Centre National de la Recherche Scientifique. He also leads the
Immunology  Department  and  the  newly  created  Cancer  Immunotherapy  Center  at  Institut  Curie  in  Paris  (France).  Dr.  Amigorena  has  made  significant
contributions to immunology and cell biology at every stage of his career. His findings have helped advance the understanding of antigen presentation and T
cell priming by dendritic cells, with applications in the fields of cancer immunotherapy and vaccination. Dr. Amigorena has received numerous national and
international prizes and awards, including the prestigious senior European Research Council award in 2008 and in 2014.

Aurélien Marabelle, MD, Ph.D., is the Clinical Director of the Cancer Immunotherapy Program at Gustave Roussy Cancer Center in Villejuif, France. Dr.
Marabelle’s clinical practice is dedicated to early phase clinical trials in cancer immunotherapy and his translational research is focused on mechanisms of
action of immune checkpoint monoclonal antibodies. He works as a senior medical oncologist and an investigator in the Drug Development Department. He
is coordinating a team focused on cancer immunotherapy translational research projects at INSERM.

Ruslan  Medzhitov,  Ph.D.,  is  a  Sterling  Professor  at  Yale  University  School  of  Medicine  in  New  Haven,  Connecticut  and  an  Investigator  of  the  Howard
Hughes Medical Institute. His research interests include biology of inflammation, biological bases of diseases and evolutionary design of biological systems.
Dr. Medzhitov is a member of the National Academy of Sciences, National Academy of Medicine and European Molecular Biology Organization. He is a
fellow of the American Academy of Microbiology and a foreign member of the Russian Academy of Sciences.

Miriam Merad, M.D., Ph.D., is the Mount Sinai Chair professor in Cancer Immunology and the Director of the Precision Immunology Institute at Mount
Sinai  School  of  Medicine  in  New  York.  Dr.  Merad’s  laboratory  studies  the  contribution  of  macrophages  and  dendritic  cells  to  Cancer  and  Inflammatory
diseases in mice and humans. She has shown that tissue macrophages have unique functional attributes that contribute to tumor outcome and response to
treatment. Dr. Merad pioneered mapping the regulatory network of dendritic cells resulting in the identification of a lineage of dendritic cells, the CD103+
DC, that is now considered to be a key target to improve antiviral and antitumor immunity. Dr. Merad receives generous funding from the National Institutes
of Health, or NIH, for her research on innate immunity and their contribution to human disease and belongs to several NIH consortia.

Tanguy Seiwert, M.D., is Assistant Professor of Medicine, Section of Hematology and Oncology in the Department of Medicine at the University of Chicago.
Dr. Seiwert’s research focuses on the biology of head and neck cancer and lung cancer. In the laboratory, he studies targeted therapies that disrupt specific
pathways vital to cancer growth and metastasis. More specifically, he focuses on which novel drugs appear most promising, which individual tumors are
more likely to respond to these treatments and how to successfully combine therapies. Dr. Seiwert uses this preclinical knowledge to develop new treatments
for use in clinical trials, and to ultimately improve patient care.

Mario Sznol, M.D., is a Professor of Medicine, Leader, Melanoma/RCC Disease-Associated Research Team, and co-leader, Cancer Immunology Program at
the Yale Cancer Center in New Haven, Connecticut. Recently, he was appointed the incoming President of the Society for Immunotherapy of Cancer. Dr.
Sznol’s  interests  include  cancer  immunotherapy,  drug  development  for  cancer  and  treatment  of  patients  with  melanoma  and  renal  cell  carcinoma. After
completing a fellowship in medical oncology at Mount Sinai College of Medicine in New York in 1987, he joined the National Cancer Institute, or NCI, as a
Senior Investigator in the Investigational Drug Branch, or IDB, Cancer Therapy Evaluation Program, or CTEP. He was Head of the Biologics Evaluation
Program,  IDB,  CTEP,  from  1994  to  1999,  and  in  1999,  was  appointed  Vice  President  of  Clinical  Development  for  Vion  Pharmaceuticals  in  New  Haven,
Connecticut. He joined the Yale faculty in medical oncology in 2004.

Executive Committee

We also have an Executive Committee composed of members with significant experience in strategy, financial management, medical research, research and
development project management, the negotiation of industrial and commercial agreements in the field of innovative companies, including biotechnology
companies,  compliance  and  regulations  and  in  business  development.  The  Executive  Committee  meets  at  least  once  a  month  and  deals  with  all  subject
regarding the activities and the management of the company.

The  current  members  of  the  Executive  Committee  are  Mondher  Majoubi,  Yannis  Morel,  Laure-Hélène  Mercier,  Pierre  Dodion,  Odile  Belzunce,  Jennifer
Butler,  Frédérique  Brune,  Tracy  Rossin  and  Odile  Laurent.  Eric  Vivier,  our  Senior  Vice  President,  Chief  Scientific  Officer,  is  a  permanent  guest  to  the
meetings of the Executive Committee.

Corporate Governance Practices

As a French société anonyme, we are subject to various corporate governance requirements under French law. We are a “foreign private issuer” under the
U.S.  federal  securities  laws  and  the  Nasdaq  listing  rules.  The  foreign  private  issuer  exemption  permits  us  to  follow  home  country  corporate  governance
practices  instead  of  certain  Nasdaq  listing  requirements.  A  foreign  private  issuer  that  elects  to  follow  a  home  country  practice  instead  of  Nasdaq  listing
requirements must submit to Nasdaq a written statement from an independent counsel in such issuer’s home country certifying that the issuer’s practices are
not prohibited by the home country’s laws.

We apply the AFEP/MEDEF code, which recommends that a majority of the members of the Supervisory Board be independent (as such term is defined
under the code). Neither the corporate laws of France nor our bylaws requires that (i) our compensation committee include only independent members of the
Supervisory Board, (ii) each committee of the Supervisory Board have a formal written charter or (iii) our independent members of the Supervisory Board
hold  regularly  scheduled  meetings  at  which  only  independent  members  of  the  Supervisory  Board  are  present.  We  intend  to  follow  French  corporate
governance practices in lieu of Nasdaq listing requirements for each of the foregoing.

These exemptions do not modify the independence requirements for the audit committee, and we intend to comply with the requirements of the Sarbanes-
Oxley Act and the Nasdaq listing rules, which require that our audit committee be composed of at least three independent members. Rule 10A-3 under the
Exchange  Act  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.  Under  Rule  10A-3,  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 of the Company, 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 our 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 share capital be at least 33 1/3% of the
outstanding shares of the company’s ordinary voting shares. We intend to follow our French home country practice, rather than complying with this Nasdaq
rule.  Consistent  with  French  Law,  our  bylaws  provide  that  when  first  convened,  general  meetings  of  shareholders  may  validly  convene  only  if  the
shareholders  present  or  represented  hold  at  least  (1)  20%  of  the  voting  shares  in  the  case  of  an  ordinary  general  meeting  or  of  an  extraordinary  general
meeting where shareholders are voting on a capital increase by capitalization of reserves, profits or share premium, or (2) 25% of the voting shares in the
case  of  any  other  extraordinary  general  meeting.  If  such  quorum  required  by  French  law  is  not  met,  the  meeting  is  adjourned.  There  is  no  quorum
requirement  under  French  law  when  an  ordinary  general  meeting  or  an  extraordinary  general  meeting  is  reconvened  where  shareholders  are  voting  on  a
capital increase by capitalization of reserves, profits or share premium, but the reconvened meeting may consider only questions that were on the agenda of
the adjourned meeting. When any other extraordinary general meeting is reconvened, the required quorum under French law is 20% of the shares entitled to
vote. If a quorum is not met at a reconvened meeting requiring a quorum, then the meeting may be adjourned for a maximum of two months.

Code of Ethics

We have adopted a Code of Ethics applicable to all of our employees and members of our Executive Board and Supervisory Board. The Code of Ethics is
available on our website. We expect that any amendments to the Code of Ethics, or any waivers of its requirements, will be disclosed on our website.

Executive Compensation Arrangements

Except the arrangements described in “Item 7.B—Related Party Transactions—Arrangements with the Members of our Executive and Supervisory Boards,”
there are no arrangements or understanding between us and any of our other members of our Executive and Supervisory Boards providing for benefits upon
termination of their employment, other than as required by applicable law.

D. Employees.

As of December 31, 2019, we had 235 full-time employees. None of our employees are represented by collective bargaining agreements. We believe that we
maintain good relations with our employees. As of December 31, 2019, of our 235 full-time employees, 214 were based in France and 21 were based in the
United States. The following tables show the number of employees as of December 31, 2019 broken out by department and entity:

Item 7. Major Shareholders and Related Party Transactions.

A.       Major Shareholders.

The following table and accompanying footnotes sets forth, as of December 31, 2019, 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 Board and Supervisory Board members individually; and

all of our Executive Board and Supervisory Board members as a group.

Assuming  that  all  of  our  ordinary  shares  represented  by  ADSs  are  held  by  residents  of  the  United  States,  as  of  December  31,  2019,  we  estimate  that
approximately 14.9 million shares, or 19% of our ordinary shares were held of record by 13 residents of the United States.

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  March  31,  2019  and  options  and
warrants that are currently exercisable or exercisable within 60 days of March 31, 2019. Ordinary shares subject to free shares, options and warrants currently
exercisable or exercisable within 60 days of March 31, 2019 are deemed to be outstanding for computing the percentage ownership of the person holding
these  free  shares,  options  or  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  ordinary  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 Securities
Act.

Unless otherwise indicated, the address of each beneficial owner listed in the table below is c/o Innate Pharma S.A., 117, Avenue de Luminy – BP 30191,
13009 Marseille, France.

2020. 

The significant changes in the percentage ownership held by our principal shareholders since January 1, 2017 are a result of the transactions described in our
prospectus dated October 16, 2019, filed with the SEC pursuant to Rule 424(b), under the heading “Certain Relationships and Related Party Transactions—
Transactions with Our Principal Shareholders” and the dilution resulting from our public offering.

None of our principal shareholders has voting rights different than our other shareholders.

B.       Related Party Transactions.

Since January 1, 2019, we have engaged in the following transactions with members of our Executive and Supervisory Boards and holders of more than 5%
of our outstanding voting securities, and their respective affiliates, which we refer to as our related parties.

Transactions With Our Principal Shareholders

AstraZeneca

In October 2019, we entered into a supply agreement with AstraZeneca relating to the exclusive manufacturing and supply by AstraZeneca of Lumoxiti in
connection with its commercialization in the U.S., the European Union., the United Kingdom and Switzerland.

Arrangements with the Members of our Executive and Supervisory Boards

Director and Executive Officer Compensation

See  “Item  6.B—Compensation—Limitations  on  Liability  and  Indemnification  Matters”  for  information  regarding  compensation  of  the  members  of  our
Supervisory and Executive Boards.

Agreement with Jean-Yves Blay

On September 14, 2018, we entrusted Jean-Yves Blay, a member of our Supervisory Board, with a specific mission pursuant to article L.225-84 of the French
Commercial Code. Based on Mr. Blay’s scientific and medical qualifications, we have agreed that he will attend meetings of our Strategic Advisory Board
consisting  of  at  least  one  meeting  that  he  attends  in-person  and  approximately  two  conference  calls  per  year.  Mr.  Blay  will  participate  in  these  Strategic
Advisory  Board  meetings  and  then  present  a  report  to  the  Supervisory  Board,  at  least  once  a  year,  on  his  opinions  of  the  Strategic  Advisory  Board’s
proceedings. This agreement will remain in place for the duration of Mr. Blay’s term of office as a member of the Supervisory Board, including any renewal
terms. We have agreed to pay Mr. Blay €10,000 in compensation for his performance of these additional duties. During the year ended December 31, 2019,
Mr. Blay did not participate to the meeting of the Strategic Advisory Board meeting and therefore was not paid for these additional duties.

Agreement with Patrick Langlois

On March 19, 2019, we entrusted Mr. Langlois with a specific mission pursuant to article L.225-84 of the French Commercial Code. This mission ended
December 31, 2019 and consisted in, during the 2019 financial year (i) ensuring that the Company has an efficient economic and legal structure to respond to
the evolution towards a commercial activity, (ii) share his experience in the deployment of and our Enterprise Resource Planning system and (iii) accompany
the evolution of the organization of the Company for its introduction on the Nasdaq. As compensation for this mission, Mr. Langlois received a compensation
amounting to € 25,000 (on top of his compensation as member of the Supervisory board and Chairman of the Audit Committee).

Indemnification Agreements

We entered into indemnification agreements with each of our Executive Board and Supervisory Board members. See the section of this Annual Report titled
“Item 6B—Compensation.”

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.

Transaction with Related Companies

From  time  to  time,  in  the  ordinary  course  of  our  business,  we  may  contract  for  services  from  companies  or  institutions  in  which  certain  members  of  our
Executive Board or Supervisory Board may serve as a director or advisor. The cost and provision of these services are negotiated on an arms-length basis and
none of these

Related Person Transaction Policy

We comply with French law regarding approval of transactions with related parties. On September 12, 2019, the Supervisory Board 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  immediately  upon  the  execution  of  the  underwriting  agreement  for  the  October  2019  global  offering.  For  purposes  of  our  policy
only,  a  related  person  transaction  is  a  transaction,  arrangement  or  similar  contractual  relationship,  or  any  series  of  similar  transactions,  arrangements  or
relationships, in which we and any related person are, were or will be participants and the amount involved in the transaction exceeds $120,000, with the
exception  of  usual  transactions  concluded  under  normal  conditions.  A  related  person  is  any  member  of  the  Executive  Board  or  Supervisory  Board  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.

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 the Supervisory Board 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 member of our Executive Board and
Supervisory  Board  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.

In addition, under our Code of Business Conduct and Ethics, which we adopted on September 12, 2019, our employees and Executive and Supervisory Board
members 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, the Supervisory Board, 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 the independence of a member of the Executive Board or Supervisory Board in the event that the related person is a member of the
Executive Board or Supervisory Board, immediate family member of a member of the Executive Board or Supervisory Board or an entity with which
a member of Executive Board or Supervisory Board 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, the Supervisory Board 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 the Supervisory Board
determines in the good faith exercise of its discretion.

220

 
 
 
 
 
 
 
 
 
 
 
 
 
 
All of the transactions described above were entered into prior to the adoption of the written policy, but our Supervisory Board evaluated and approved all
transactions that were considered to be related party transactions under French law at the time at which they were consummated.

C.       Interests of Experts and Counsel.

Not applicable.

Item 8. Financial Information.

A.       Consolidated Statements and Other Financial Information.

Consolidated Financial Statements

Our consolidated financial statements are included as part of this Annual Report, starting at page F-1.

Legal Proceedings

From time to time, we may be involved in various claims and legal proceedings relating to claims arising out of our operations. We are not currently a party
to  any  legal  proceedings  that,  in  the  opinion  of  our  management,  are  likely  to  have  a  material  adverse  effect  on  our  business.  Regardless  of  outcome,
litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Dividend Policy

We have never declared or paid any 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.

Strategic Collaborations and License Agreements

AstraZeneca

2015 Agreements

In April 2015, we entered into two agreements with MedImmune, a wholly owned subsidiary of AstraZeneca, which we refer to as AstraZeneca. The first
agreement was a co-development and license agreement relating to certain combination products containing monalizumab, or the Original Co-Development
Agreement,  and  the  second  agreement  was  a  development  and  option  agreement  for  products  containing  monalizumab,  including  products  using
monalizumab as a monotherapy, or the 2015 Option Agreement. We received an initial payment of $250 million under these agreements on June 30, 2015, of
which $100 million was paid to us as an initial payment for the Original Co-Development Agreement and $150 million was paid to us as consideration for
the 2015 Option Agreement described below. In October 2018, AstraZeneca exercised its option under the 2015 Option Agreement, which resulted in the
automatic termination of both the Original Co-Development Agreement and the 2015 Option Agreement, and a new co-development and license agreement
relating to all products containing monalizumab, or the 2015 Co-Development Agreement, automatically came into effect. In connection with AstraZeneca’s
exercise of its option under the 2015 Option Agreement, an upfront payment of $100 million was due under the 2015 Co-Development Agreement, which it
paid in January 2019.

2015 Co-Development Agreement

Under  the  2015  Co-Development  Agreement,  we  granted  to AstraZeneca  a  worldwide,  exclusive  license,  subject  to  certain  exclusions,  to  certain  of  our
patents  and  know-how  to  develop,  manufacture  and  commercialize  licensed  products,  including  monalizumab,  in  the  field  of  diagnosis,  prevention  and
treatment  of  oncology  diseases  and  conditions.  We  further  granted  to  AstraZeneca  a  worldwide,  non-exclusive  license  to  certain  of  our  other  patents  to
develop, manufacture and commercialize licensed products, including monalizumab, in the field of diagnosis, prevention and treatment of oncology diseases
and  conditions.  We  retain  the  rights  under  the  licensed  patents  and  know-how  to,  among  other  things,  co-promote  licensed  products  in  certain  European
countries, pursuant to our option to co-promote, and exploit the licensed patents and know-how to research, develop and commercialize the licensed products
outside of the field of diagnosis, prevention and treatment of oncology diseases and conditions.

Under the 2015 Co-Development Agreement, we are required to collaborate with AstraZeneca to develop and commercialize licensed products. AstraZeneca
will be the lead party in developing the licensed products and licensed product in certain major markets. Each party will have to use commercially reasonable
efforts to complete certain development activities in accordance with a specified development plan.

We  are  required  for  a  defined  period  of  time  to  co-fund  30%  of  the  Phase  III  clinical  trials  of  licensed  products,  subject  to  an  aggregate  cap,  in  order  to
receive 50% of the profits in Europe.

223

 
 
 
 
 
 
 
 
 
 
 
 
On  July  31,  2019,  we  notified  AstraZeneca  of  our  decision  to  co-fund  a  future  monalizumab  Phase  III  clinical  development  program.  Additionally,  in
September  2019,  we  announced  that  AstraZeneca  will  advance  monalizumab  into  a  Phase  III  randomized  clinical  trial  evaluating  monalizumab  in
combination  with  cetuximab,  and  that  we  and  AstraZeneca  will  co-fund  the  clinical  trial.  AstraZeneca  will  be  responsible  for  the  promotion  of  licensed
products worldwide, subject to our option to co-promote the licensed products in certain European countries. Should we elect not to co-promote, our share of
profits in Europe will be reduced by a specified amount of percentage points not to exceed the mid-single digits.

The development by AstraZeneca of a licensed product under the 2015 Co-Development Agreement is subject to certain reciprocal non-compete obligations.

AstraZeneca  is  obligated  to  pay  us  up  to  $925  million  in  the  aggregate  upon  the  achievement  of  certain  development  and  regulatory  milestones  ($500
million),  which  includes  $100  million  we  expect  to  receive  upon  dosing  of  the  first  patient  in  the  first  Phase  III  clinical  trial  for  monalizumab,  and
commercialization milestones ($425 million). As described above, the arrangement also provides for a 50% profit share and, subject to certain deferrals of
reimbursement,  loss  share  of  licensed  products  in  Europe  if  we  do  not  opt  out  of  our  co-funding  and  co-promoting  obligations.  In  addition,  we  will  be
eligible to receive tiered royalties ranging from a low double-digit to mid-teen percentage on net sales of licensed products outside of Europe. The royalties
payable  to  us  under  the  2015  Co-Development  Agreement  may  be  reduced  under  certain  circumstances,  including  loss  of  exclusivity  or  lack  of  patent
protection.

Our right to receive royalties under the 2015 Co-Development Agreement expires, on a licensed product-by-licensed product and country-by-country basis,
on the latest of: (i) the tenth anniversary of the first commercial sale of such licensed product in such country, or in the case of European countries, in any
European country, (ii) the expiration of regulatory exclusivity for such licensed product in such country and (iii) the expiration of the last-to-expire valid
licensed patent claim subject to the agreement that covers such licensed product in such country.

Unless earlier terminated, the term of the 2015 Co-Development Agreement will expire on the date on which all of AstraZeneca’s payment obligations have
expired. We may terminate the 2015 Co-Development Agreement if AstraZeneca challenges any patent licensed to it under the agreement. AstraZeneca may
terminate the 2015 Co-Development Agreement in its entirety for convenience at any time effective upon 120 days’ prior written notice to us. Either party
may terminate the 2015 Co-Development Agreement in the event of an uncured material breach by the other party or for certain bankruptcy or insolvency
events involving the other party.

If the 2015 Co-Development Agreement is terminated by AstraZeneca for convenience or by us for AstraZeneca’s material breach, insolvency or a patent
challenge by AstraZeneca, all licenses and rights granted under the agreement terminate, however, upon any such termination, AstraZeneca would grant us
an exclusive, worldwide, royalty-bearing right and license, with the right to grant sublicenses, under technology developed by AstraZeneca and incorporated
into or necessary for the exploitation of licensed products, except for certain manufacturing technology that would require a separate agreement. If the 2015
Co-Development Agreement is terminated by AstraZeneca for our material breach or insolvency, AstraZeneca has the right to continue the agreement by
providing written notice to us. If AstraZeneca provides us with such written notice, among other things, our rights under the co-promote option will terminate
and we must cease any development, manufacture or commercialization activities under the agreement.

224

 
 
 
 
 
 
 
 
 
 
2018 Agreements

In October 2018, we entered into three agreements with AstraZeneca. The first agreement is a collaboration and option agreement relating to IPH5201, or the
2018 CD39 Option Agreement. We received an initial payment of $50 million under this agreement, $26 million of which was received in October 2018 and
$24 million of which was received in January 2019. The second agreement is an option agreement relating to four pre-clinical programs, which we refer to as
the 2018 Future Programs Option Agreement. We received an initial payment of $20 million under this agreement in October 2018. The third agreement is a
license agreement with AstraZeneca relating to Lumoxiti, or the Lumoxiti Agreement. We made an initial payment to AstraZeneca of $50 million under this
agreement in January 2019.

2018 CD39 Option Agreement

Pursuant to the 2018 CD39 Option Agreement, we granted to AstraZeneca an exclusive option to obtain an exclusive license to certain of our patents and
know-how to develop and commercialize licensed products, including IPH5201 in the field of the diagnosis, prevention and treatment of all diseases and
conditions in humans or animals, subject to certain limitations.

Under  the  2018  CD39  Option  Agreement,  we  must  collaborate  with  AstraZeneca  to  develop  CD39  option  products.  Prior  to  the  expiration  of  the  option
period, we and AstraZeneca are subject to certain non-compete obligations.

AstraZeneca  is  responsible  for  funding  the  research  and  development  costs  of  CD39  option  products  contemplated  in  the  joint  development  plan.
Additionally, we may conduct certain exploratory clinical studies at our own cost, subject to reimbursement by AstraZeneca with a premium under certain
circumstances related to subsequent development by AstraZeneca.

Following the dosing of the first patient on March 9, 2020 in the IPH5201 Phase I clinical trial, AstraZeneca made a $5 million milestone payment to Innate
under  the  companies’  October  2018  multi-product  oncology  development  collaboration.  Pursuant  to  the  2018  CD39  Option  Agreement,  AstraZeneca  is
obligated to pay us up to $5 million in the aggregate upon the achievement of certain development milestones.

Unless earlier terminated, the term of the 2018 CD39 Option Agreement will expire on the earlier of exercise of the option or expiration of the option period
in the event that AstraZeneca does not exercise the option. We may terminate the 2018 CD39 Option Agreement if AstraZeneca challenges any option patent.
AstraZeneca may terminate the 2018 CD39 Option Agreement in its entirety for convenience at any time effective upon three months’ prior written notice to
us. Either party may terminate the 2018 CD39 Option Agreement in the event of an uncured material breach by the other party or for certain bankruptcy or
insolvency events involving the other party.

225

 
 
 
 
 
 
 
 
 
 
 
 
CD39 Co-Development and License Agreement Upon Option Exercise by AstraZeneca

Upon exercise of the option under the 2018 CD39 Option Agreement, we would enter into a co-development and license agreement with AstraZeneca, or the
CD39 Potential License Agreement. Under the CD39 Potential License Agreement, we would grant to AstraZeneca a worldwide, exclusive license, subject to
certain  exclusions,  to  certain  of  our  patents  and  know-how  regarding,  among  other  things,  our  IPH5201  candidate,  to  develop,  manufacture  and
commercialize licensed products in the field of diagnosis, prevention and treatment of diseases and conditions in humans and in animals, subject to certain
limitations.  We  would  retain  certain  rights  under  the  licensed  patents  and  know-how  to,  among  other  things,  co-promote  licensed  products  in  certain
European countries, pursuant to our option to co-promote.

The CD39 Potential License Agreement provides for a payment of $25 million upon exercise. Additionally, AstraZeneca would be obligated to pay us up to
$795  million  in  the  aggregate  upon  the  achievement  of  certain  development  and  regulatory  milestones  ($295  million)  and  commercialization  milestones
($500 million). The arrangement also provides for a 50% profit share in Europe if we opt into certain co-promoting and late stage co-funding obligations. In
addition, we would be eligible to receive tiered royalties ranging from a high-single digit to mid-teen percentage on net sales of IPH5201, or from a mid-
single digit to low-double digit percentage on net sales of other types of licensed products, outside of Europe. The royalties payable to us under the CD39
Potential License Agreement may be reduced under certain circumstances, including loss of exclusivity or lack of patent protection.

Under the CD39 Potential License Agreement, unless we have elected not to co-fund, we would be required to collaborate with AstraZeneca to develop and
commercialize licensed products. AstraZeneca would be the lead party in developing and commercializing the licensed products and each party must use
commercially reasonable efforts to develop, obtain regulatory approval and commercialize at least one licensed product in certain major markets. Each party
would have to use commercially reasonable efforts to complete its development activities in accordance with a specified development plan.

We would have the option to co-fund 30% of the Phase III clinical trials of licensed products in order to share in 50% of the profits and losses of licensed
products in Europe. If we do not exercise this co-funding option, among other things, our right to share in 50% of the profits and losses in Europe and right to
co-promote in certain European countries will terminate and will be replaced by rights to receive royalties on net sales at the rates applicable to outside of
Europe.  Additionally,  certain  milestone  payments  that  may  be  payable  to  us  would  be  reduced. AstraZeneca  would  be  responsible  for  the  promotion  of
licensed products worldwide, subject to our option to co-promote the licensed products in certain European countries if we elect to co-fund. Additionally, we
would have a right of first negotiation in the event that AstraZeneca wishes to grant a third-party the right to commercialize licensed products in Europe or
the United States.

The development by AstraZeneca of a licensed product under the Potential License Agreement is subject to certain reciprocal non-compete obligations.

Our right to receive royalties under the CD39 Potential License Agreement expires, on a licensed product-by-licensed product and country-by-country basis,
on the latest of: (i) the tenth anniversary of the first commercial sale of such licensed product in such country, or, in the case of European countries, in any
European country, (ii) the expiration of regulatory exclusivity for such licensed product in such country and (iii) the expiration of the last-to-expire valid
licensed patent claim subject to the agreement that covers such licensed product in such country.

226

 
 
 
 
 
 
 
 
 
 
 
Unless earlier terminated, the term of the CD39 Potential License Agreement would expire on the date on which all of AstraZeneca’s payment obligations
have  expired.  We  may  terminate  the  CD39  Potential  License  Agreement  if  AstraZeneca  challenges  any  patent  licensed  to  it  under  the  agreement.
AstraZeneca may terminate the CD39 Potential License Agreement in its entirety for convenience at any time effective upon 120 days’ prior written notice to
us. Either party may terminate the CD39 Potential License Agreement in the event of an uncured material breach by the other party or for certain bankruptcy
or insolvency events involving the other party.

2018 Future Programs Option Agreement

Pursuant to the 2018 Future Programs Option Agreement, we granted to AstraZeneca four exclusive options that are exercisable until IND approval to obtain
a  worldwide,  royalty-bearing,  exclusive  license  to  certain  of  our  patents  and  know-how  relating  to  certain  specified  pipeline  candidates  to  develop  and
commercialize  optioned  products  in  all  fields  of  use.  The  relevant  programs  are  IPH43,  IPH25,  the  anti-Siglec-9  antibody  program  and  a  multi-specific
NKp46  NKCE  program.  Upon  exercise  of  an  option,  we  would  be  entitled  to  an  option  exercise  payment  of  $35  million,  as  well  as  development  and
regulatory milestone payments ($320 million) and commercialization milestone payments ($500 million) and tiered, mid-single digit to mid-teen percentage
royalties on net sales of the applicable product. The royalties payable to us may be reduced under certain circumstances, including loss of exclusivity, lack of
patent  protection  or  the  specific  nature  of  the  compound  included  within  the  applicable  product.  Additionally,  we  would  have  rights  to  co-fund  certain
development costs in order to obtain profit and loss sharing in Europe. So long as we elect to co-fund such development costs, we also will have a right to co-
promote optioned products in Europe.

License Agreement for Lumoxiti

Pursuant to the Lumoxiti Agreement, we obtained an exclusive license under certain patents and know-how of AstraZeneca to develop, manufacture and
commercialize Lumoxiti for all uses in humans and animals in the United States, the European Union and Switzerland. We are obligated to pay AstraZeneca
up to $25 million in the aggregate upon the achievement of certain regulatory and commercial milestones. In connection with the Lumoxiti Agreement, we
also  obtained  an  exclusive  sublicense  from  AstraZeneca  under  certain  third-party  intellectual  property  rights.  In  consideration  for  such  sublicense  we  are
obligated to pay a low single digit royalty on our net sales of Lumoxiti, as well as milestone payments up to approximately $1 million in the aggregate.

Under  the  Lumoxiti  Agreement,  AstraZeneca  is  obligated  to  provide  support  for  the  continued  development  and  commercialization  of  Lumoxiti  in  the
European  Union  and  Switzerland  prior  to  regulatory  submission  and  approval  as  well  as  support  for  the  continued  commercialization  of  Lumoxiti  in  the
United States for a specified period. We will reimburse AstraZeneca for the development, production and commercialization costs it will incur during the
transition period, subject to certain limitations for the year ended December 31, 2019. In addition, pursuant to the Lumoxiti Agreement we entered into a
supply  agreement  with  AstraZeneca  relating  to  the  exclusive  manufacturing  and  supply  by  AstraZeneca  of  Lumoxiti  in  connection  with  its
commercialization in the U.S., the European Union., the United Kingdom and Switzerland.

227

 
 
 
 
 
 
 
 
 
 
Under the Lumoxiti Agreement, we have a right of first negotiation in the event that AstraZeneca intends to grant rights to commercialize Lumoxiti outside
of the United States, the European Union and Switzerland.

The Lumoxiti Agreement will expire on a country-by-country basis upon the latest of (i) the expiry of the last exclusively licensed patent in such country, (ii)
expiration of any regulatory exclusivity in such country, and (iii) the fifteenth anniversary of the first commercial sale of Lumoxiti in such country. Either
party may terminate the Lumoxiti Agreement upon any uncured material breach of such party’s obligations under the agreement or upon a bankruptcy or
insolvency of the other party. Additionally, AstraZeneca may terminate the agreement in the event we challenge any patent exclusively licensed under the
agreement or cease to perform all commercial activities with respect to Lumoxiti in the United States or the European Union for a specified period of time.
We may terminate the Lumoxiti Agreement upon certain prior notice to AstraZeneca.

Additional agreements related to Monalizumab

Novo Nordisk A/S

On February 5, 2014, we in-licensed the full development and commercialization rights to monalizumab relating to the modulation of the activity of isolated
NK cells from Novo Nordisk A/S. In consideration for these rights, we paid Novo Nordisk A/S €2 million in cash and 600,000 of our ordinary shares at a
price of €8.33 per share. Novo Nordisk A/S is eligible to receive a total of €20 million in potential regulatory milestones and tiered mid-to-high single-digit
percentage royalties on future net sales.

The agreement with Novo Nordisk A/S included a right to additional consideration in the event of an out-licensing agreement. Consequently, following the
agreement signed with AstraZeneca in April 2015, we paid Novo Nordisk A/S an additional consideration amount of €6.5 million.

In October 2018 AstraZeneca exercised its option under the 2015 Option Agreement to acquire an exclusive license to monalizumab. Pursuant to this option
exercise, AstraZeneca paid $100 million to us and, as a result, Novo Nordisk A/S became entitled to a second and final payment amounting to $15.0 million
(€13.1  million).  If  the  AstraZeneca  agreement  is  terminated  for  any  reason,  we  will  pay  to  Novo  Nordisk  A/S  a  portion  of  any  amounts  that  have  been
budgeted but have not been spent or will not be spent under the initial research and development budget. In light of current development plans and research
and development costs incurred to date, we do not currently expect any amounts to be paid pursuant to this provision.

License Agreement with Novo Nordisk for avdoralimab

In July of 2017 we entered into an exclusive license agreement with Novo Nordisk A/S relating to avdoralimab, or the 2017 Novo Agreement, pursuant to
which we obtained a worldwide, exclusive license under certain patents and know-how of Novo Nordisk A/S to develop, manufacture and commercialize
pharmaceutical products that contain or comprise an Anti-C5aR antibody. We made an initial payment to Novo Nordisk A/S of €40.0 million under the 2017
Novo Agreement which was offset against Novo Nordisk A/S’s subscription in new shares. We are obligated to pay Novo Nordisk A/S in the aggregate up to
€370.0 million upon achievement of certain development, regulatory and sales milestones and tiered royalties ranging from a low double-digit to low teen
percentage on net sales. Our royalty payment obligations are subject to certain reductions and expire on a product-by-product and country-by-country basis
upon the later of the date the exploitation of a licensed product is no longer covered by a claim of a licensed patent in such country, loss of data or regulatory
exclusivity  in  such  country,  and  the  twelfth  anniversary  of  the  first  commercial  sale  of  such  product  in  such  country.  In  connection  with  the  2017  Novo
Agreement,  we  obtained  an  exclusive  sublicense  from  Novo  Nordisk  A/S  under  certain  third-party  intellectual  property  rights.  In  consideration  for  such
sublicense we may be obligated to pay a mid-single digit royalty on our net sales of a licensed product, however, we will be entitled to offset such payments
against royalties payable to Novo Nordisk A/S.

228

 
 
 
 
 
 
 
 
 
 
 
 
 
Under the 2017 Novo Agreement, we are obligated to use commercially reasonable efforts to develop and seek regulatory approval for a licensed product.

The 2017 Novo Agreement shall expire upon expiration of the last royalty payment obligation under the agreement. Either party may terminate the 2017
Novo Agreement upon any uncured material breach of the agreement by the other party or upon a bankruptcy or insolvency of the other party. Additionally,
Novo  Nordisk  A/S  may  terminate  the  agreement  in  the  event  we  challenge  any  patent  licensed  under  the  agreement.  We  may  terminate  the  2017  Novo
Agreement upon prior notice to Novo Nordisk A/S.

Collaboration and licensing agreement with Sanofi

We entered into a research collaboration and licensing agreement with Sanofi in January 2016 to apply our proprietary technology to the development of
bispecific  antibody  formats  engaging  NK  cells  to  kill  tumor  cells  through  the  activating  receptor  NKp46.  We  granted  to  Sanofi  under  certain  of  our
intellectual  property  a  non-exclusive,  worldwide,  royalty-free  research  license,  as  well  as  an  exclusive,  worldwide  license  to  research,  develop  and
commercialize products directed against two specified targets, for all therapeutic, prophylactic and diagnostic indications and uses.

We  will  work  together  with  Sanofi  on  the  generation  and  evaluation  of  up  to  two  bispecific  NK  cell  engagers,  using  our  technology  and  Sanofi’s  tumor
targets. Under the terms of the license agreement, Sanofi will be responsible for the development, manufacturing and commercialization of products resulting
from the research collaboration. We will be eligible for up to €400.0 million in payments, primarily upon the achievement of development and commercial
milestones, as well as royalties ranging from a mid to high single-digit percentage on net sales.

Orega License Agreement

Pursuant to our licensing agreement with Orega Biotech, we acquired an exclusive license to Orega Biotech’s intellectual property rights relating to its anti-
CD39 checkpoint inhibitor program. As of December 31, 2018, we had paid a total amount of €1.8 million to Orega Biotech for the acquisition of these
intellectual property rights, and in June of 2019 we paid Orega Biotech €7.0 million in relation to the anti-CD39 program as consideration relating to the
collaboration and option agreement signed on October 22, 2018 with AstraZeneca for IPH5201. Following the dosing of the first patient on March 9, 2020 in
the IPH5201 Phase I clinical trial, AstraZeneca made a $5 million milestone pursuant to our collaboration agreement with AstraZeneca and are obligated to
make a €2.7 million milestone payment to Orega Biotech SAS pursuant to our licensing agreement with Orega Biotech SAS. We may also be obligated to
pay Orega Biotech up to an additional €48.8 million in the aggregate upon the achievement of development and regulatory milestones, and mid-single digit
to low-teen percentage payments, depending on determinations relating to Orega Biotech’s intellectual property rights for certain patents, on sublicensing
revenues we receive pursuant to our agreement with AstraZeneca relating to IPH5201.

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.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds our ordinary shares or ADSs, the tax consequences relating to
an  investment  in  our  ordinary  shares  or ADSs  will  depend  in  part  upon  the  status  of  the  partner  and  the  activities  of  the  partnership.  Such  a  partner  or
partnership should consult its tax advisor regarding the specific tax considerations of acquiring, owning and disposing of our ordinary shares or ADSs in its
particular circumstances.

Persons  considering  an  investment  in  our  ordinary  shares  or  ADSs  should  consult  their  own  tax  advisors  as  to  the  particular  tax  consequences
applicable to them relating to the acquisition, ownership and disposition of our ordinary shares or ADSs, including the applicability of U.S. federal,
state and local tax laws, French tax laws and other non-U.S. tax laws.

This description does not address the U.S. federal estate, gift, or alternative minimum tax considerations, the Medicare tax on net investment income or any
U.S. state, local, or non-U.S. tax considerations of the acquisition, ownership and disposition of our ordinary shares or ADSs.

231

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
This description 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  of  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 below. There can be no
assurances that the U.S. Internal Revenue Service, or the IRS, will not take a position concerning the tax consequences of the acquisition, ownership and
disposition of our ordinary shares or ADSs or that such a position would not be sustained by a court. We have not obtained, nor do we intend to obtain, a
ruling with respect to the U.S. federal income tax considerations of the purchase, ownership or disposition of our ordinary shares or ADSs. Accordingly,
holders should consult their own tax advisors concerning the U.S. federal, state, local and non-U.S. tax consequences of acquiring, owning and disposing of
our ordinary shares or ADSs in their particular circumstances.

As  indicated  below,  this  summary  is  subject  to  the  discussion  below  of  the  U.S.  federal  income  tax  rules  applicable  to  a  “passive  foreign  investment
company,” or a PFIC.

In general, and taking into account the earlier assumptions, for U.S. federal income tax purposes, a U.S. holder holding ADSs will be treated as the owner of
the ordinary shares represented by the ADSs. Exchanges of ordinary shares for ADSs, and ADSs for ordinary shares, generally will not be subject to U.S.
federal income tax.

Distributions.  Subject  to  the  discussion  under  “—Passive  Foreign  Investment  Company  Considerations,”  below,  the  gross  amount  of  any  distribution
(including any amounts withheld in respect of foreign tax) actually or constructively received by a U.S. holder with respect to our ordinary shares or ADSs
will generally 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 generally 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 our ordinary shares or 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 has held our ordinary shares or ADSs for more than 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 our ordinary shares or ADSs applicable to long-term capital gains (i.e., gains from the sale of
capital assets held for more than one year), or qualified dividend income if we are a “qualified foreign corporation” and certain other requirements are met. A
non-U.S. corporation (other than a corporation that is 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 provision 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 listed on the
Nasdaq Global Select Market, which is an established securities market in the United States, and we believe the ADSs are readily tradable on the Nasdaq
Global Select Market. There can be no assurance that the ADSs will continue to be considered readily tradable on an established securities market in the
United States in later 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  rules  and  that  it  includes  an  exchange-of-information  program.  Therefore,
subject  to  the  discussion  under  “—Passive  Foreign  Investment  Company  Considerations,”  below,  such  dividends  will  generally  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. The dividends will not be
eligible for the dividends-received deduction generally allowed to corporate U.S. holders.

232

 
 
 
 
 
 
 
 
A U.S. holder generally may claim the amount of any French withholding tax on a distribution as either a deduction from gross income or a credit against its
U.S. federal income tax liability. The foreign tax credit is subject to numerous complex limitations that must be determined and applied on an individual
basis. Generally, the credit 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
bears to such U.S. holder’s worldwide taxable income. In applying this limitation, a U.S. holder’s various items of income and deduction must be classified,
under  complex  rules,  as  either  “foreign  source”  or  “U.S.  source.”  In  addition,  the  creditability  of  foreign  taxes  could  be  affected  by  actions  taken  by
intermediaries in the chain of ownership between the holders of our ordinary shares or ADSs and our company if, as a result of such actions, the holders of
our ordinary shares or ADSs are not properly treated as beneficial owners of the underlying ordinary shares. Each U.S. holder should consult its own 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, in the case of the ADSs, or on the day the distribution is received by
the U.S. holder, in the case of ordinary shares, 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.

Sale,  Exchange  or  Other  Taxable  Disposition. A  U.S.  holder  will  generally  recognize  gain  or  loss  for  U.S.  federal  income  tax  purposes  upon  the  sale,
exchange or other taxable disposition of our ordinary shares or ADSs in an amount equal to the difference between the amount realized from such sale or
exchange and the U.S. holder’s adjusted tax basis in those ordinary shares or ADSs, each as determined in U.S. dollars. Subject to the discussion under “—
Passive Foreign Investment Company Considerations” below, this gain or loss will generally be a capital gain or loss. The adjusted tax basis in our ordinary
shares  or  ADSs  generally  will  be  equal  to  the  U.S  dollar  cost  of  such  ordinary  shares  or  ADSs.  Capital  gain  from  the  sale,  exchange  or  other  taxable
disposition of our ordinary shares or ADSs by 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 ordinary shares or 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.

233

 
 
 
 
 
 
 
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 our ordinary shares
or ADSs that are traded on an established securities market, provided 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.

Passive Foreign Investment Company Considerations. If we are a PFIC in any taxable year, a U.S. holder will be subject to special rules generally intended
to reduce or eliminate any benefits from the deferral of U.S. federal income tax that a U.S. holder could derive from investing in a non-U.S. company that
does not distribute all of its earnings on a current basis.

We will be a PFIC for U.S. federal income tax purposes in any taxable year in which, after applying certain look-through rules with respect to the income and
assets of our subsidiaries, either: (1) at least 75% of the gross income is “passive income” or (2) at least 50% of the average quarterly value of our total gross
assets (which would generally be measured by fair market value of our assets, and for which purpose the total value of our assets may be determined in part
by the market value of the ADSs and our ordinary shares, which are subject to change) is attributable to assets that produce “passive income” or are held for
the production of “passive income.”

234

 
 
 
 
 
 
 
 
Passive  income  for  this  purpose  generally  includes  dividends,  interest,  royalties,  rents,  gains  from  commodities  and  securities  transactions,  the  excess  of
gains over losses from the disposition of assets which produce passive income, and includes amounts derived by reason of the temporary investment of funds
raised  in  offerings  of  our  ordinary  shares  or  ADSs.  If  a  non-U.S.  corporation  owns  directly  or  indirectly  at  least  25%  by  value  of  the  stock  of  another
corporation, the non-U.S. corporation is treated for purposes of the PFIC tests as owning its proportionate share of the assets of the other corporation and as
receiving directly its proportionate share of the other corporation’s income. The determination of whether we are a PFIC is a fact-intensive determination
made on an annual basis and the applicable law is subject to varying interpretation. If we are a PFIC in any taxable year during which a U.S. holder owns our
ordinary shares or ADSs, such U.S. holder will be subject to special tax rules discussed below and could suffer adverse tax consequences.

The market value of our assets may be determined in large part by reference to the market price of the ADSs and our ordinary shares. Therefore, fluctuations
in the market price of our ordinary shares or ADSs may result in our being a PFIC for any taxable year. Whether we are a PFIC for any taxable year will
depend on income, assets, activities and market capitalization in each year, and because this is a factual determination made annually after the end of each
taxable year, there can be no assurance that we will not be a PFIC in any taxable year. We do not believe we were characterized as a PFIC in our taxable year
ended December 31, 2019. However, there can be no assurance that we will not be a PFIC in the current year or for any future taxable year. Our U.S. counsel
expresses no opinion regarding our conclusions or our expectations regarding our PFIC status.

If we are a PFIC in any year with respect to which a U.S. holder owns our ordinary shares or ADSs, we will continue to be treated as a PFIC with respect to
such U.S. holder in all succeeding years during which the U.S. holder owns the ordinary shares or ADSs, regardless of whether we continue to meet the tests
described above unless we cease to be a PFIC and the U.S. holder has made a “deemed sale” election under the PFIC rules or is eligible to make and makes a
mark-to-market  election  (as  described  below),  with  respect  to  all  taxable  years  during  such  U.S.  holder’s  holding  period  in  which  we  are  a  PFIC.  If  the
“deemed sale” election is made, a U.S. holder will be deemed to have sold the ordinary shares or ADSs the U.S. holder holds at their fair market value as of
the date of such deemed sale and any gain from such deemed sale would be subject to the rules described below. After the deemed sale election, so long as
we do not become a PFIC in a subsequent taxable year, the U.S. holder’s ordinary shares or ADSs with respect to which such election was made will not be
treated as shares in a PFIC and the U.S. holder will not be subject to the rules described below with respect to any “excess distribution” the U.S. holder
receives from us or any gain from an actual sale or other disposition of the ordinary shares or ADSs. U.S. holders should consult their tax advisors as to the
possibility and consequences of making a deemed sale election if such election becomes available.

235

 
 
 
 
 
 
 
If we are a PFIC, and you are a U.S. holder that does not make one of the elections described above (and below in further detail), a special tax regime will
apply  to  both  (a)  any  “excess  distribution”  by  us  to  you  (generally,  your  ratable  portion  of  distributions  in  any  year  which  are  greater  than  125%  of  the
average annual distribution received by you in the shorter of the three preceding years or your holding period for our ordinary shares or ADSs) and (b) any
gain realized on the sale or other disposition of our ordinary shares or ADSs. Under this regime, any excess distribution and realized gain will be treated as
ordinary income and will be subject to tax as if (a) the excess distribution or gain had been realized ratably over your holding period for our ordinary shares
or ADSs, (b) the amount deemed realized in each year had been subject to tax in each 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 year and would not be subject to the interest charge discussed below), and (c) the interest charge generally applicable to
underpayments of tax had been imposed on the taxes deemed to have been payable in those years. In addition, dividend distributions made to you will not
qualify for the lower rates of taxation applicable to qualified dividends discussed above under “Distributions.”

Certain elections may alleviate some of the adverse consequences of PFIC status and would result in an alternative treatment of our ordinary shares or ADSs.
If a 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 our
ordinary shares or 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 our ordinary shares or 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). If a U.S. holder makes the election, the U.S. holder’s tax basis in our ordinary shares
or ADSs will be adjusted to reflect these income or loss amounts. Any gain recognized on the sale or other disposition of our ordinary shares or ADSs in a
year in which we are a PFIC will be treated as ordinary income and any loss will be treated as an ordinary loss (but only to the extent of the net amount of
income  previously  included  as  a  result  of  the  mark-to-market  election).  The  mark-to-market  election  is  available  only  if  we  are  a  PFIC  and  our  ordinary
shares or ADSs are “regularly traded” on a “qualified exchange.” Our ordinary shares or ADSs will be treated as “regularly traded” in any calendar year in
which more than a de minimis quantity of our ordinary shares or 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 a U.S.
holder. It should be noted that only the ADSs and not our ordinary shares are listed on the Nasdaq Global Select Market. Consequently, our ordinary shares
may not be marketable if Euronext Paris (where our ordinary shares are listed) does not meet the applicable requirements. U.S. holders should consult their
tax advisors regarding the availability of the mark-to-market election for ordinary shares that are not represented by ADSs.

However, a mark-to-market election generally cannot be made for equity interests in any lower-tier PFICs that we own, unless shares of such lower-tier PFIC
are themselves “marketable.” As a result, even if a U.S. holder validly makes a mark-to-market election with respect to our ordinary shares or ADSs, the U.S.
holder may continue to be subject to the PFIC rules (described above) with respect to its indirect interest in any of our investments that are treated as an
equity interest in a PFIC for U.S. federal income tax purposes. U.S. holders should consult their tax advisors as to the availability and desirability of a mark-
to-market election, as well as the impact of such election on interests in any lower-tier PFICs.

236

 
 
 
 
 
 
 
We do not currently intend to provide the information necessary for U.S. holders to make a “qualified electing fund elections” if we were treated as a PFIC
for any taxable year. U.S. holders should consult their tax advisors to determine whether this election would be available and if so, what the consequences of
the alternative treatments would be in their particular circumstances.

If we were a PFIC, the general tax treatment for U.S. holders described in this section would apply to indirect distributions and gains deemed to be realized
by U.S. holders in respect of any of our subsidiaries that also may be PFICs. U.S. holders should consult their tax advisors regarding the application of the
PFIC rules to our subsidiaries.

If a U.S. holder owns our ordinary shares or 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  the  company,
generally with the U.S. holder’s federal income tax return for that year. If our company were a PFIC for a given taxable year, then you should consult your
tax advisor concerning your annual filing requirements.

The U.S. federal income tax rules relating to PFICs are complex. Prospective U.S. investors are urged to consult their own tax advisors with respect
to the acquisition, ownership and disposition of our ordinary shares or ADSs, the consequences to them of an investment in a PFIC, any elections
available with respect to our ordinary shares or ADSs and the IRS information reporting obligations with respect to the acquisition, ownership and
disposition of our ordinary shares or ADSs.

Backup Withholding and Information Reporting. U.S. holders generally will be subject to information reporting requirements with respect to dividends on
our ordinary shares or ADSs and on the proceeds from the sale, exchange or disposition of our ordinary shares or 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.

237

 
 
 
 
 
 
 
 
 
Foreign Asset Reporting. Certain individual U.S. holders are required to report information relating to an interest in our ordinary shares or 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  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 ownership and disposition of our ordinary shares or ADSs.

THE  DISCUSSION  ABOVE  IS  A  SUMMARY  OF  THE  U.S.  FEDERAL  INCOME  TAX  CONSEQUENCES  OF  AN  INVESTMENT  IN  OUR
ORDINARY SHARES OR ADSs AND IS BASED UPON LAWS AND RELEVANT INTERPRETATIONS THEREOF IN EFFECT AS OF THE
DATE  OF  THIS  ANNUAL  REPORT,  ALL  OF  WHICH  ARE  SUBJECT  TO  CHANGE,  POSSIBLY  WITH  RETROACTIVE  EFFECT.  EACH
PROSPECTIVE  INVESTOR  IS  URGED  TO  CONSULT  ITS  OWN  TAX  ADVISOR  ABOUT  THE  TAX  CONSEQUENCES  TO  IT  OF  AN
INVESTMENT IN OUR ORDINARY SHARES OR ADSs IN LIGHT OF THE INVESTOR’S OWN CIRCUMSTANCES.

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.

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.

In 2011, France introduced a comprehensive set of 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 former French wealth tax (replaced by the French real estate wealth tax
as from January 1, 2018), 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 former French wealth tax (replaced by the French real estate wealth tax as from January 1, 2018) 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 advised to consult their own tax advisor regarding the specific tax
consequences of acquiring, owning and disposing of such securities.

The description of the French income tax and real estate wealth tax consequences set forth below is based on the double tax treaty entered into 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 (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, or the Treaty.

This discussion applies only to investors that are entitled to Treaty benefits under the “Limitation on Benefits” provisions contained in the Treaty.

If a partnership holds ADSs, the tax treatment of the partnership and a partner in such partnership generally will depend on the status of the partner and the
activities of the partnership. Such partner or partnership is urged to consult its own tax advisor regarding the specific tax consequences of acquiring, owning
and disposing of ADSs.

238

 
 
 
 
 
 
 
 
 
 
 
 
 
This discussion applies only to investors that hold ADSs as capital assets that are entitled to Treaty benefits under the “Limitation on Benefits” provision
contained in the Treaty, and whose ownership of the ADSs is not effectively connected to a permanent establishment or a fixed base in France. Certain U.S.
holders may be subject to special rules not discussed below, and are advised to consult their usual tax advisor regarding the specific tax consequences which
may apply to their particular situation.

U.S. holders are advised to consult their own tax advisor regarding the tax consequences of the purchase, ownership and disposition of ADSs in light of their
particular circumstances, especially with regard to the “Limitations on Benefits” provision contained in the Treaty.

Tax on Sale or other Disposals

As a matter of principles, 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 certain non-cooperative States or territories as
defined in Article 238-0 A of the French tax code (Code général des impôts, 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).

Under application of the Treaty, a U.S. holder who is a U.S. resident for purposes of the Treaty and entitled to Treaty benefits will not be subject to French
tax on 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 advisor 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 benefits (and in both cases is not resident, established or incorporated in
certain non-cooperative States or territories as defined in Article 238-0 A of the FTC) and has held more than 25% of our dividend rights, known as “droits
aux bénéfices 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 (i) at the rate of 12.8% for individuals, and (ii) a rate corresponding to the standard corporate income tax rate set forth in Article
219-I of the FTC for legal persons. Special rules apply to U.S. holders who are residents of more than one country.

239

 
 
 
 
 
 
 
 
 
Financial Transactions Tax and Registration Duties

Pursuant to Article 235 ter ZD of the 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 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. A list of companies whose market capitalization exceeds 1
billion euros as of December 1 of the year preceding the taxation year, within the meaning of Article 235 ter ZD of the FTC, is published annually by the
French tax authorities in their official guidelines. As at 1 December 2019, our market capitalization did not exceed 1 billion euros, pursuant to BOI-ANNX-
000467-20191218.

Moreover, Nasdaq Global Select Market, on which ADSs are listed, is not currently acknowledged by the AMF but this may change in the future.

As a consequence, neither the ADSs nor the ordinary shares are currently within the scope of the French tax on financial transactions.

Purchases of our ADSs may be subject to such tax in the future provided that our market capitalization exceeds 1 billion euros in the year preceding the
taxation year 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  are  listed  on  a  regulated  or
organized market within the meaning of the French monetary code (Code monétaire et financier) 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. As ordinary shares of our company are listed on
Euronext  Paris,  which  is  an  organized  market  within  the  meaning  of  the  French  monetary  code,  their  transfer  should  be  subject  to  uncapped  registration
duties at the rate of 0.1% subject to the existence of a written statement (“acte”), and provided that Article 235 ter ZD of the FTC is not applicable. Although
there is no case law or official guidelines published by the French tax authorities on this point, transfer of ADSs should remain outside of the scope of the
aforementioned 0.1% registration duties.

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  (i)  28%  for  fiscal  years
beginning  on  or  after  January  1st,  2020,  26.5%  for  fiscal  years  beginning  on  or  after  January  1st,  2021  and  25%  for  fiscal  years  beginning  on  or  after
January 1st, 2022, for payment benefiting legal persons which are not French tax residents, and (ii) 12.8% for payment benefiting individuals who are not
French tax residents. Dividends paid by a French corporation in certain non-cooperative States or territories, 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 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 28% (to be decreased
respectively to 26.5% and 25% in 2021 and 2022) or 75% withholding tax rate, but may be subject to the withholding tax at a reduced rate (as described
below).

240

 
 
 
 
 
 
 
 
 
 
 
 
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, is generally 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 advisor 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 French guidelines (BOI-INT-DG-20-20-20-20-20120912 dated September 12, 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, if such U.S. holder is a legal person, will be subject to French withholding tax at the rate of 28% (to be decreased
respectively to 26.5% and 25% in 2021 and 2022), or 75% if paid in certain non-cooperative States or territories (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 28% (to be decreased respectively to 26.5% and 25% in 2021 and
2022) 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.

241

 
 
 
 
 
 
 
 
 
 
 
In any case, individual taxpayers who are not fiscally domiciled in France should not have to comply with these procedures if the French withholding tax
applying to them is lower than 15%.

Estate and Gift 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  double  tax  treaty  entered  into  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, 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 ADSs were used in, or held for use in, the conduct of a business through a permanent establishment or a fixed base in France.

Wealth Tax

As from January 1, 2018, the French wealth tax (impôt de solidarité sur la fortune) is repealed and replaced by the French real estate wealth tax (impôt sur la
fortune immobilière). The scope of such new tax is narrowed to French real estate assets (and certain assets deemed to be real estate assets) or rights, held
directly or indirectly through one or more legal entities and whose net taxable assets amount at least to €1,300,000.

Broadly,  subject  to  provisions  of  double  tax  treaties  and  to  certain  exceptions,  individuals  who  are  not  residents  of  France  for  tax  purposes  within  the
meaning of Article 4 B of the FTC, are subject to real estate wealth tax (impôt sur la fortune immobilière) in France in respect of the portion of the value of
their  shares  of  our  company  representing  real  estate  assets  (Article  965,  2°  of  the  FTC).  Some  exceptions  are  provided  by  the  FTC.  For  instance,  any
participations representing less than 10% of the share capital of an operational company and shares representing real estate for the professional use of the
company considered shall not fall within the scope of the French real estate wealth tax (impôt sur la fortune immobilière).

Under the Treaty (the provisions of which should be applicable to this new real estate wealth tax (impôt sur la fortune immobilière) in France), the French
real estate wealth tax (impôt sur la fortune immobilière) will however generally not apply to securities held by an eligible U.S. holder who is a U.S. resident,
as  defined  pursuant  to  the  provisions  of  the  Treaty,  provided  that  such  U.S.  holder  (i)  does  not  own  directly  or  indirectly  more  than  25%  of  the  issuer’s
financial rights and (ii) that the ADSs do not form part of the business property of a permanent establishment or fixed base in France.

U.S. holders are advised to consult their own tax advisor regarding the specific tax consequences which may apply to their particular situation with respect to
such French real estate wealth tax (impôt sur la fortune immobilière).

H.       Documents on Display.

We are subject to the information reporting requirements of the Exchange Act applicable to foreign private issuers and under those requirements will file
reports with the SEC. Those reports may be inspected without charge at the locations described below. As a foreign private issuer, we are exempt from the
rules under the Exchange Act related to the furnishing and content of proxy statements, and our officers, directors and principal shareholders are exempt
from  the  reporting  and  short-swing  profit  recovery  provisions  contained  in  Section  16  of  the  Exchange  Act.  In  addition,  we  are  not  required  under  the
Exchange Act to file periodic reports and financial statements with the SEC as frequently or as promptly as United States companies whose securities are
registered under the Exchange Act. Nevertheless, we will file with the SEC an Annual Report on Form 20-F containing financial statements that have been
examined and reported on, with an opinion expressed by an independent registered public accounting firm.

We maintain a corporate website at www.innate-pharma.com. We intend to post our Annual Report on Form 20-F on our website promptly following it being
filed with the SEC. Information contained on, or that can be accessed through, our website does not constitute a part of this Annual Report. We have included
our website address in this Annual Report solely as an inactive textual reference.

The Securities and Exchange Commission maintains a website (www.sec.gov) that contains reports, proxy and information statements and other information
regarding registrants, such as us, that file electronically with the SEC.

Item 11. Quantitative and Qualitative Disclosures About Market Risk.

Our activities are exposed to liquidity risk, foreign currency exchange risk, interest rate risk and credit risk.

Liquidity risk

We do not believe that we are exposed to short-term liquidity risk, considering our cash and cash equivalents of €202.9 million as of December 31, 2019,
which consist primarily of cash and money market funds and term deposits that are convertible into cash immediately without penalty.

Foreign currency exchange rate risk

We are exposed to foreign exchange risk inherent in certain subcontracting activities related to our operations in the United States, which are invoiced in U.S.
dollars. We do not currently have material recurring revenues in euro, dollars or in any other currency. As we further increase our business, particularly in the
United States, we expect to face greater exposure to exchange rate risk.

243

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Our  revenue  denominated  in  U.S.  dollars  has  represented  approximately  100%  of  revenue  in  the  years  ended  December  31,  2017,  2018  and  2019.  Our
payments  in  U.S.  dollars  represented  approximately  15.1%  31.9%  and  64.1%,  of  our  payments  in  the  years  ended  December  31,  2017,  2018  and  2019,
respectively. In order to cover this foreign currency exchange rate risk, we kept in U.S. dollars a part of the consideration received from AstraZeneca in June
2015 and January 2019. . We kept the entire U.S dollars portion of the proceeds received from our October 2019 global offering in U.S dollars. We do not use
hedging instruments.

Interest rate risk

We have limited exposure to interest rate risk. Our exposure primarily relates to 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. We do not have any credit facilities bearing variable interest
rates. The repayment of the advances from BPI France is not subject to interest rate risk. The effect of an increase or decrease in interest rates would have an
immaterial effect on profit or loss.

Credit risk

The credit risk related to our cash equivalents, short-term investments and non-current financial assets is not significant in light of the quality of the issuers.
We deemed that no instrument of its portfolio is exposed to credit risk.

D.       American Depositary Shares.

Citibank, N.A. acts as the depositary bank for the ADSs. Citibank’s depositary offices are located at 388 Greenwich Street, New York, New York 10013.
ADSs represent ownership interests in securities that are on deposit with the depositary bank. ADSs may be represented by certificates that are commonly
known as American Depositary Receipts, or ADRs. The depositary bank typically appoints a custodian to safekeep the securities on deposit. In this case, the
custodian is Citibank Europe plc, 1 North Wall Quay, Dublin 1, Ireland.

We have appointed Citibank, N.A. as depositary bank pursuant to a deposit agreement. A copy of the deposit agreement has been filed with the SEC under
cover of a Registration Statement on Form F-6 (Registration No. 333-234063). You may obtain a copy of the deposit agreement from the SEC’s website at
www.sec.gov.

244

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Each ADS represents the right to receive, and to exercise the beneficial ownership interests in, one ordinary share that is on deposit with the depositary bank
and/or custodian. An ADS also represents the right to receive, and to exercise the beneficial interests in, any other property received by the depositary bank
or  the  custodian  on  behalf  of  the  owner  of  the  ADS  but  that  has  not  been  distributed  to  the  owners  of  ADSs  because  of  legal  restrictions  or  practical
considerations. We and the depositary bank may agree to change the ADS-to-Share ratio by amending the deposit agreement. This amendment may give rise
to, or change, the depositary fees payable by ADS owners. The custodian, the depositary bank and their respective nominees will hold all deposited property
for the benefit of the holders and beneficial owners of ADSs. The deposited property does not constitute the proprietary assets of the depositary bank, the
custodian or their nominees. Beneficial ownership in the deposited property will under the terms of the deposit agreement be vested in the beneficial owners
of the ADSs. The depositary bank, the custodian and their respective nominees are the record holders of the deposited property represented by the ADSs for
the benefit of the holders and beneficial owners of the corresponding ADSs. A beneficial owner of ADSs may or may not be the holder of ADSs. Beneficial
owners of ADSs are able to receive, and to exercise beneficial ownership interests in, the deposited property only through the registered holders of the ADSs,
the registered holders of the ADSs (on behalf of the applicable ADS owners) only through the depositary bank, and the depositary bank (on behalf of the
owners of the corresponding ADSs) directly, or indirectly, through the custodian or their respective nominees, in each case upon the terms of the deposit
agreement.

If you are or become an owner of ADSs, you are or will become a party to the deposit agreement and therefore are or will be bound to its terms and to the
terms of any ADR that represents your ADSs. The deposit agreement and the ADR specify our rights and obligations as well as your rights and obligations as
owner of ADSs and those of the depositary bank. As an ADS holder you appoint the depositary bank to act on your behalf in certain circumstances. The
deposit agreement and the ADRs are governed by New York law. However, our obligations to the holders of ordinary shares will continue to be governed by
the laws of France, which may be different from the laws in the United States.

In addition, applicable laws and regulations may require you to satisfy reporting requirements and obtain regulatory approvals in certain circumstances. You
are solely responsible for complying with such reporting requirements and obtaining such approvals. Neither the depositary bank, the custodian, us or any of
their or our respective agents or affiliates shall be required to take any actions whatsoever on your behalf to satisfy such reporting requirements or obtain
such regulatory approvals under applicable laws and regulations.

245

 
 
 
 
 
 
 
Fees and Expenses

Pursuant to the terms of the amended and restated deposit agreement, the holders of our ADSs are required to pay the following fees to the depositary bank:

Service
Issuance of ADSs (e.g., an issuance of ADS upon a deposit of ordinary shares, upon a
change in the ADSs-to-ordinary shares ratio, or for any other reason), excluding ADS
issuances as a result of distributions of ordinary shares)

  Fees

Up to U.S. 5¢ per ADS issued

Cancellation of ADSs (e.g., a cancellation of ADSs for delivery of deposited property,
upon a change in the ADSs-to ordinary shares ratio, or for any other reason)

Up to U.S. 5¢ per ADS cancelled

Distribution of cash dividends or other cash distributions (e.g., upon a sale of rights
and other entitlements)

Up to U.S. 5¢ per ADS held

Distribution of ADSs pursuant to (i) stock dividends or other free stock distributions,
or (ii) exercise of rights to purchase additional ADSs

Up to U.S. 5¢ per ADS held

Distribution of securities other than ADSs or rights to purchase additional ADSs (e.g.,
upon a spin-off)

Up to U.S. 5¢ per ADS held

ADS Services

Registration of ADS transfers (e.g., upon a registration of the transfer of registered
ownership of ADSs, upon a transfer of ADSs into DTC and vice versa, or for any
other reason)

Conversion of ADSs of one series for ADSs of another series (e.g., upon conversion
of Partial Entitlement ADSs for Full Entitlement ADSs, or upon conversion of
Restricted ADSs (each as defined in the Deposit Agreement) into freely transferable
ADSs, and vice versa).

246

Up to U.S. 5¢ per ADS held on the applicable record date(s)
established by the depositary bank

Up to U.S. 5¢ per ADS (or fraction thereof) transferred

Up to U.S. 5¢ per ADS (or fraction thereof) converted

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
ADS holders are responsible to pay certain charges such as:

·

·

·

·

·

·

taxes (including applicable interest and penalties) and other governmental charges;

the registration fees as may from time to time be in effect for the registration of ordinary shares on the share register and applicable to transfers of
ordinary shares to or from the name of the custodian, the depositary bank or any nominees upon the making of deposits and withdrawals, respectively;

certain cable, telex and facsimile transmission and delivery expenses;

the fees, expenses, spreads, taxes and other charges of the depositary bank and/or service providers (which may be a division, branch or affiliate of the
depositary bank) in the conversion of foreign currency;

the  reasonable  and  customary  out-of-pocket  expenses  incurred  by  the  depositary  bank  in  connection  with  compliance  with  exchange  control
regulations and other regulatory requirements applicable to ordinary shares, ADSs and ADRs; and

the fees, charges, costs and expenses incurred by the depositary bank, the custodian, or any nominee in connection with the ADR program.

ADS fees and charges for (i) the issuance of ADSs, and (ii) the cancellation of ADSs are charged to the person for whom the ADSs are issued (in the case of
ADS issuances) and to the person for whom ADSs are cancelled (in the case of ADS cancellations). In the case of ADSs issued by the depositary bank into
DTC,  the  ADS  issuance  and  cancellation  fees  and  charges  may  be  deducted  from  distributions  made  through  DTC,  and  may  be  charged  to  the  DTC
participant(s) receiving the ADSs being issued or the DTC participant(s) holding the ADSs being cancelled, as the case may be, on behalf of the beneficial
owner(s) and will be charged by the DTC participant(s) to the account of the applicable beneficial owner(s) in accordance with the procedures and practices
of the DTC participants as in effect at the time. ADS fees and charges in respect of distributions and the ADS service fee are charged to the holders as of the
applicable  ADS  record  date.  In  the  case  of  distributions  of  cash,  the  amount  of  the  applicable  ADS  fees  and  charges  is  deducted  from  the  funds  being
distributed. In the case of (i) distributions other than cash and (ii) the ADS service fee, holders as of the ADS record date will be invoiced for the amount of
the ADS fees and charges and such ADS fees and charges may be deducted from distributions made to holders of ADSs. For ADSs held through DTC, the
ADS fees and charges for distributions other than cash and the ADS service fee may be deducted from distributions made through DTC, and may be charged
to the DTC participants in accordance with the procedures and practices prescribed by DTC and the DTC participants in turn charge the amount of such ADS
fees and charges to the beneficial owners for whom they hold ADSs. In the case of (i) registration of ADS transfers, the ADS transfer fee will be payable by
the ADS Holder whose ADSs are being transferred or by the person to whom the ADSs are transferred, and (ii) conversion of ADSs of one series for ADSs
of  another  series,  the  ADS  conversion  fee  will  be  payable  by  the  Holder  whose  ADSs  are  converted  or  by  the  person  to  whom  the  converted  ADSs  are
delivered.

In the event of refusal to pay the depositary bank fees, the depositary bank may, under the terms of the deposit agreement, refuse the requested service until
payment is received or may set off the amount of the depositary bank fees from any distribution to be made to the ADS holder. Note that the fees and charges
you may be required to pay may vary over time and may be changed by us and by the depositary bank. You will receive prior notice of such changes. The
depositary bank may reimburse us for certain expenses incurred by us in respect of the ADR program, by making available a portion of the ADS fees charged
in respect of the ADR program or otherwise, upon such terms and conditions as we and the depositary bank agree from time to time.

247

 
 
 
 
 
 
 
 
 
 
 
 
 
Payment of Taxes

ADS  holders  are  responsible  for  the  taxes  and  other  governmental  charges  payable  on  the  ADSs  and  the  securities  represented  by  the  ADSs.  We,  the
depositary bank and the custodian may deduct from any distribution the taxes and governmental charges payable by holders and may sell any and all property
on deposit to pay the taxes and governmental charges payable by holders. You are be liable for any deficiency if the sale proceeds do not cover the taxes that
are due.

The depositary bank may refuse to issue ADSs, to deliver, transfer, split and combine ADRs or to release securities on deposit until all taxes and charges are
paid  by  the  applicable  holder.  The  depositary  bank  and  the  custodian  may  take  reasonable  administrative  actions  to  obtain  tax  refunds  and  reduced  tax
withholding for any distributions on your behalf. However, you may be required to provide to the depositary bank and to the custodian proof of taxpayer
status  and  residence  and  such  other  information  as  the  depositary  bank  and  the  custodian  may  require  to  fulfill  legal  obligations.  You  are  required  to
indemnify us, the depositary bank and the custodian for any claims with respect to taxes based on any tax benefit obtained for you.

Depositary Payments for 2019

From time to time, the depositary bank may make payments to us to reimburse and/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 deposit agreement, the depositary bank may use brokers, dealers or other service providers that are affiliates of the depositary
bank and that may earn or share fees or commissions. For the year ended December 31, 2019, Citibank, N.A., as depositary bank, had made reimbursements
to us of €700.7 million ($772.8 million).

October 2019 Global Offering

In October 2019, we completed a global offering of an aggregate of 14,375,000 ordinary shares, including the full exercise of the underwriters’ option to
purchase 1,875,000 additional ordinary shares. The October 2019 global offering consisted of a U.S. initial public offering of 8,047,227 ordinary shares in
the form of American Depositary Shares, each representing one ordinary share, at an offering price of $5.50 per ADS and a concurrent private placement in
Europe  and  other  countries  outside  of  the  United  States  and  Canada  of  4,452,773  ordinary  shares  at  an  offering  price  of  €4.97  per  ordinary  share  for
aggregate  gross  proceeds  to  us  of  approximately  €79.1  million  ($71.4  million).  The  net  proceeds  to  us,  after  deducting  underwriting  discounts  and
commissions and offering expenses, were approximately €66.0 million. The offering commenced on October 17, 2019 and did not terminate before all of the
securities  registered  in  the  registration  statement  were  sold.  The  effective  date  of  the  registration  statement,  File  No.  333-233865,  for  our  October  2019
global offering was October 16, 2019.

Citigroup Global Markets Inc., SVB Leerink LLC and Evercore Group L.L.C. acted as representatives of the underwriters in the U.S. offering. Citigroup
Global Markets Limited acted as a representative in the European private placement.

The net proceeds from our October 2019 global offering have been used, and are expected to continue to be used, as described in the final prospectus for the
October 2019 global offering filed with the U.S. Securities and Exchange Commission on October 16, 2019.

None  of  the  net  proceeds  of  our  October  2019  global  offering  were  paid  directly  or  indirectly  to  any  director,  officer,  general  partner  of  ours  or  to  their
associates, persons owning ten percent or more of any class of our equity securities, or to any of our affiliates.

Item 15. Controls and Procedures.

Disclosure Controls and Procedures

We maintain “disclosure controls and procedures,” as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, that are designed to
ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported
within the time periods specified in the rules and forms of the Securities and Exchange Commission. Disclosure controls and procedures include, without
limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is
accumulated  and  communicated  to  management,  including  our  chief  executive  officer  (principal  executive  officer)  and  chief  financial  officer  (principal
financial officer), as appropriate, to allow timely decisions regarding required disclosure.

249

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Our principal executive officer and principal financial officer, after evaluating the effectiveness of our disclosure controls and procedures (as defined in Rules
13a-15(e) and 15d-15(e) of the Exchange Act) as of December 31, 2019, have concluded that, as of such date, our disclosure controls and procedures were
not  effective  at  the  reasonable  assurance  level  as  a  result  of  the  material  weaknesses  described  below.  Notwithstanding  these  material  weaknesses,  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 in conformity with IFRS.

Internal Control Over Financial Reporting

As  permitted  by  the  rules  of  the  Securities  and  Exchange  Commission  for  newly  public  companies  in  the  U.S.,  our  management  has  not  completed  an
assessment of the effectiveness of our internal control over financial reporting and our independent registered public accounting firm has not conducted an
audit of our internal control over financial reporting.

During the audit of our consolidated financial statements as of and for the years ended December 31, 2019, we identified material weaknesses in our internal
control over financial reporting. A company’s internal control over financial reporting is a process designed by, or under the supervision of, a company’s
principal executive and principal financial officers, or persons performing similar functions, and effected by a company’s executive board, management and
other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with
generally  accepted  accounting  principles.  Under  standards  established  by  the  Public  Company  Accounting  Oversight  Board,  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 in
our annual or interim financial statements will not be prevented or detected and corrected on a timely basis.

In the course of auditing the consolidated financial statements as of and for the year ended December 31, 2019, several material weaknesses in our internal
control over financial reporting were identified. The material weaknesses related to (i) the accounting for subcontracting clinical costs for which there was
insufficient control on the input data coming from clinical studies and used in assessing their advancement (input data mainly includes expected termination
date of the study, overall budget and/or number of patient visits),  and (ii) the recognition of the revenue from our collaboration and licensing agreement with
AstraZeneca  on  monalizumab  for  which  there  was  insufficient  review  of  the  calculation  of  the  transaction  price  and  percentage  of  completion  of  costs
incurred.  Errors  not  detected  in  relation  to  topic  (i)  have  led  to  incorrect  amounts  of  R&D  expenses  for  the  year  ended  December  31,  2019,  which  were
subsequently  corrected  prior  to  the  issuance  of  our  audited  financial  statements.  The  material  weakness  in  relation  to  topic  (ii)  has  led  to  a  material
misstatement of revenue for the year ended December 31, 2019, which was subsequently corrected prior to the issuance of our audited financial statements.
In addition our information system, supporting the production of our financial information, also raised material weaknesses in terms of "general IT controls"
(GITC) related to the management of access rights, including segregation of duties and change management.

A  number  of  significant  deficiencies  in  our  internal  controls  have  also  been  identified  for  the  years  ended  December  31,  2017,  2018  and  2019.  Over  the
course of 2020, we continue to work to remediate these material weaknesses and strengthen our controls in these areas.

Changes in Internal Control over Financial Reporting

Planning system to equip our company with robust and standard tools and reinforce the reliability of our financial operations and information. See “Item 3D.

provides, such as consents and assistance with and review of documents filed with the SEC.

“Non-audit fees”  are  the  aggregate  fees  billed  for  services  related  to  the  production  of  certification  in  the  context  of  the  declaration  of  expenses  for  the
obtention of grants and the preparation of special reports relating to certain operations on the Company’s capital.

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.

252

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
   
   
   
 
 
 
 
 
 
 
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 Deloitte & Associés as described above and believes that they are compatible with
maintaining Deloitte & Associés’s independence as our independent registered public accounting firm.

Item 16D. Exemptions from the Listing Standards for Audit Committees.

Not applicable.

Item 16E. Purchases of Equity Securities by the Issuer and Affiliated Purchasers.

Not applicable.

Item 16F. Change in Registrant’s Certifying Accountant.

Not applicable.

Item 16G. Corporate Governance.

As a French société anonyme, we are subject to various corporate governance requirements under French law. We are a “foreign private issuer” under the
U.S. federal securities laws and the Nasdaq listing rules. The foreign private issuer exemption will permit us to follow home country corporate governance
practices  instead  of  certain  Nasdaq  listing  requirements.  A  foreign  private  issuer  that  elects  to  follow  a  home  country  practice  instead  of  Nasdaq  listing
requirements must submit to Nasdaq a written statement from an independent counsel in such issuer’s home country certifying that the issuer’s practices are
not prohibited by the home country’s laws.

We apply the AFEP/MEDEF code, which recommends that a majority of the members of the Supervisory Board be independent (as such term is defined
under the code). Neither the corporate laws of France nor our bylaws requires that (i) our compensation committee include only independent members of the
Supervisory Board, (ii) each committee of the Supervisory Board have a formal written charter or (iii) our independent members of the Supervisory Board
hold  regularly  scheduled  meetings  at  which  only  independent  members  of  the  Supervisory  Board  are  present.  We  intend  to  follow  French  corporate
governance practices in lieu of Nasdaq listing requirements for each of the foregoing.

These exemptions do not modify the independence requirements for the audit committee, we intend to comply with the requirements of the Sarbanes-Oxley
Act  and  the  Nasdaq  listing  rules,  which  require  that  our  audit  committee  be  composed  of  at  least  three  independent  members.  Rule  10A-3  under  the
Exchange  Act  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.  Under  Rule  10A-3,  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 of the Company, 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 our shareholders at our annual meeting.

253

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In addition, Nasdaq rules require that a listed company specify that the quorum for any meeting of the holders of share capital be at least 33 1/3% of the
outstanding shares of the company’s ordinary voting shares. We intend to follow our French home country practice, rather than complying with this Nasdaq
rule.  Consistent  with  French  Law,  our  bylaws  provide  that  when  first  convened,  general  meetings  of  shareholders  may  validly  convene  only  if  the
shareholders  present  or  represented  hold  at  least  (1)  20%  of  the  voting  shares  in  the  case  of  an  ordinary  general  meeting  or  of  an  extraordinary  general
meeting where shareholders are voting on a capital increase by capitalization of reserves, profits or share premium, or (2) 25% of the voting shares in the
case  of  any  other  extraordinary  general  meeting.  If  such  quorum  required  by  French  law  is  not  met,  the  meeting  is  adjourned.  There  is  no  quorum
requirement  under  French  law  when  an  ordinary  general  meeting  or  an  extraordinary  general  meeting  is  reconvened  where  shareholders  are  voting  on  a
capital increase by capitalization of reserves, profits or share premium, but the reconvened meeting may consider only questions that were on the agenda of
the adjourned meeting. When any other extraordinary general meeting is reconvened, the required quorum under French law is 20% of the shares entitled to
vote. If a quorum is not met at a reconvened meeting requiring a quorum, then the meeting may be adjourned for a maximum of two months.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Innate Pharma

Opinion on the Financial Statements

We have audited the accompanying consolidated statements of financial position of Innate Pharma S.A. and subsidiaries (the "Company") as of December 31,
2019, 2018 and 2017, the related consolidated statements of income (loss), comprehensive income (loss), cash flows and changes in shareholders' equity, for
each of the three years in the period ended December 31, 2019, and the related notes (collectively referred to as the "financial statements"). In our opinion, the
financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2019, 2018 and 2017, and the results of
its operations and its cash flows for each of the three years in the period ended December 31, 2019, in conformity with International Financial Reporting
Standards as issued by the International Accounting Standards Board (IASB).

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial
statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB)
and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of
the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor
were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of
internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial
reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the
financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating
the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

robust preclinical pipeline. The Company has entered into collaborations with leaders in the biopharmaceutical industry, such as AstraZeneca and Sanofi.

From its inception, the Company has incurred losses due to its research and development (“R&D”) activity. The financial year ended December 31, 2019
generated a €20,759 thousand net loss. As of December 31, 2019, the shareholders’ equity amounted to €217,416 thousand. Subject to potential new milestone
payments  related  to  its  collaboration  agreements,  the  Company  anticipates  incurring  additional  losses  until  such  time,  if  ever,  that  it  can  generate  significant
revenue from its product candidates in development.

The  Company’s  future  operations  are  highly  dependent  on  a  combination  of  factors,  including:  (i)  the  success  of  its  R&D;  (ii)  regulatory  approval  and
market acceptance of the Company’s future product candidates; (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 equity instruments.

The Company’s activity is not subject to seasonal fluctuations.

As of December 31, 2019, the Company had two wholly owned subsidiaries: Innate Pharma, Inc., incorporated under the laws of Delaware in 2009, and

Innate Pharma France SAS, incorporated under the laws of France in 2018.

Innate Inc.'s vocation is to market Innate Pharma's products in the United States, in particular Lumoxiti.

Innate Pharma France SAS aims in particular to:

(i) exploit any commercial license granted by a third-party;

(ii) to carry out, on its behalf or on behalf of third parties, all research, development, studies, development of production and marketing processes for
products of pharmaceutical interest and more generally relevant the health sector;

(iii) the registration or granting of any patent or license relating directly or indirectly to its activity;

F-9

 
 
 
 
 
 
 
 
 
 
 
 
(iv) manufacture, import and distribute drugs intended for human experimentation;

(v) manufacture, use and import medicines and other products whose sale is reserved for pharmacists.

These two subsidiaries are fully consolidated.

1. 1. Significant contracts

The following paragraphs describe the key provisions of significant contracts.

a) Agreements related to monalizumab with Novo Nordisk A/S and with AstraZeneca

2014 Novo Nordisk A/S monalizumab agreement

On February 5, 2014, the Company acquired from Novo Nordisk A/S full development and commercialization rights to monalizumab. Novo Nordisk A/S
received €2.0 million in cash and 600,000 ordinary shares at a price of €8.33 per share (€5.0 million). Novo Nordisk A/S is eligible to receive up to €20.0 million
in potential regulatory milestones and single-digit tiered royalties on sales of monalizumab products. The agreement with Novo Nordisk A/S included a right to
additional consideration in the event of an out-licensing agreement. Consequently, following the agreement signed with AstraZeneca in April 2015 (as described
below),  the  Company  paid  to  Novo  Nordisk  A/S  additional  consideration  of  €6.5  million  (paid  in  April  2016).  Following  the  exercise  of  the  option  by
AstraZeneca  in  October  2018  (as  described  below),  Novo  Nordisk  A/S  became  entitled  to  a  second  and  final  additional  payment  amounting  to  $15.0  million
(€13.1 million) which was recognized as a liability as of December 31, 2018 and was paid in February 2019. There are no other potential additional milestones
payments due to Novo Nordisk A/S. These amounts were added to the net book value of the intangible asset and are amortized according to the same amortization
plan as the initial €7.0 million recognized in 2014. The net book value of the license amounted to €7.9 million as of December 31, 2019.

Refer to Notes 2.k, 2.l and 6 for accounting description.

2015 AstraZeneca monalizumab agreements

Under  co-development  and  option  agreements  signed  with  AstraZeneca  in  2015,  the  Company  granted  to  AstraZeneca  an  exclusive  license,  subject  to
certain exclusions, to certain of its patents and know-how to develop, manufacture and commercialize licensed products, including monalizumab, in the field of
diagnosis,  prevention  and  treatment  of  oncology  diseases  and  conditions.  The  Company  further  granted  to  AstraZeneca  a  worldwide,  non-exclusive  license  to
certain  of  its  other  patents  to  develop,  manufacture  and  commercialize  licensed  products,  including  monalizumab,  in  the  field  of  diagnosis,  prevention  and
treatment of oncology diseases and conditions.

The Company received an initial payment of $250 million under these agreements in June 2015, of which $100 million was paid to the Company as an
initial payment for the co-development agreement and $150 million was paid to the Company as consideration for the option agreement. On October 22, 2018,
AstraZeneca exercised this option, triggering the payment of $100.0 million, which was received by the Company in January 2019.

Following  the  option  exercise,  AstraZeneca  became  the  lead  party  in  developing  the  licensed  products  and  must  use  commercially  reasonable  efforts  to

develop, obtain regulatory approval for and commercialize each licensed product in certain major markets.

In addition to the initial payment and option exercise payment, AstraZeneca is obligated to pay the Company up to $925 million in the aggregate upon the
achievement  of  certain  development  and  regulatory  milestones  ($500  million)  and  commercialization  milestones  ($425  million).  The  Company  is  eligible  to
receive tiered royalties ranging from a low double-digit to mid-teen percentage on net sales of licensed products outside of Europe. The Company is required for a
defined period of time to co-fund 30% of the Phase III clinical trials of licensed products, subject to an aggregate cap, in order to receive 50% of the profits in
Europe.

F-10

 
 
 
 
 
 
 
 
 
 
 
 
 
In July 31, 2019, the Company notified AstraZeneca of its decision to co-fund a future monalizumab Phase III clinical development program.

If the Company had chosen not to exercise its option of co-promoting licensed products in certain European countries, it would have forfeited the option to
co-promote licensed products under the agreement, and its right to share in 50% of such profits would terminate and sales in Europe would have been instead be
factored into net sales used to calculate royalty and milestone payments to it. Additionally, Phase III and regulatory milestone payments that may be payable to the
Company would have been reduced and AstraZeneca would have been responsible for the promotion of licensed products worldwide, subject to the Company’s
option  to  co-promote  the  licensed  products  in  certain  European  countries.  In  addition,  its  share  of  profits  in  Europe  would  have  been  reduced  by  a  specified
amount of percentage points not to exceed the mid-single digits

Refer to Notes 2.a, 2.s and 13.a for accounting description.

b) Agreement related to Lumoxiti with AstraZeneca

In October 2018, the Company obtained an exclusive license from AstraZeneca under certain patents and know-how to develop, manufacture and
commercialize Lumoxiti for all uses in humans and animals in the United States, the European Union and Switzerland. Under this Agreement, AstraZeneca is
obligated to provide support for the continued development and commercialization of Lumoxiti in the European Union and Switzerland prior to regulatory
submission and approval as well as support for the continued commercialization of Lumoxiti in the United States for a specified period. The Company initiated in
2019 to transition to full commercialization responsibilities, which is expected to be completed by the end of 2020. Under the agreement, the Company was
obligated to pay a $50.0 million initial payment (€43.8 million), which it paid in January 2019, and a $15.0 million regulatory milestone (€13.4 million), which
was paid in January 2020. The Company has reimbursed and will reimburse AstraZeneca for the development, production and commercialization costs it incurs
during the transition period.

Refer to Notes 2.t and 15 for accounting description.

c) Agreement related to IPH5201 with AstraZeneca

In October 2018, the Company signed a collaboration and option agreement with AstraZeneca for co-development and co-commercialization of IPH5201.
Under the agreement, AstraZeneca paid the Company a $50.0 million upfront payment ($26.0 million paid in October 2018 and $24.0 million paid in January
2019), and is obligated to pay the Company up to an aggregate of $10.0 million upon the achievement of certain development milestones. Upon exercise of its
option  under  the  agreement,  AstraZeneca  is  committed  to  pay  an  option  exercise  fee  of  $25.0  million  and  up  to  $800.0  million  in  the  aggregate  upon  the
achievement of certain development and regulatory milestones ($300 million) and commercialization milestones ($500 million). The arrangement also provides
for a 50% profit share in Europe if the Company opts into certain co-promoting and late stage co-funding obligations. In addition, we would be eligible to receive
tiered royalties ranging from a high-single digit to mid-teen percentage on net sales of IPH5201, or from a mid-single digit to low-double digit percentage on net
sales  of  other  types  of  licensed  products,  outside  of  Europe.  The  royalties  payable  to  us  under  the  agreement  may  be  reduced  under  certain  circumstances,
including loss of exclusivity or lack of patent protection. The Company recognized €18.8 million as revenue from proceeds related to this agreement for the year
ended December 31, 2019, and was also reimbursed by AstraZeneca for certain research and development expenses related to IPH5201. The Company has the
option to co-fund 30% of the shared development expenses related to the Phase III clinical trials in order to acquire co-promotion rights and to share in 50% of the
profits and losses of licensed products in Europe. If the Company does not opt into the co-funding obligations, among other things, its right to share in 50% of the
profits and losses in Europe and right to co-promote in certain European countries will terminate and will be replaced by rights to receive royalties on net sales at
the rates applicable to outside of Europe. Additionally, certain milestone payments that may be payable to the Company would be materially reduced.

Refer to Notes 2.s and 13.b for accounting description.

d) Agreement related to additional preclinical molecules with AstraZeneca

In  October  2018,  the  Company  granted  to  AstraZeneca  four  exclusive  options  that  are  exercisable  until  IND  approval  to  obtain  a  worldwide,  royalty-
bearing,  exclusive  license  to  certain  of  the  Company’s  patents  and  know-how  relating  to  certain  specified  pipeline  candidates  to  develop  and  commercialize
optioned products in all fields of use. Pursuant to the agreement, AstraZeneca paid the Company a $20.0 million upfront payment (€17.5 million) in October 2018.
The Company recognizes this upfront payment in the consolidated statement of financial position as deferred revenue as of December 31, 2018, until the exercise
or the termination of each option at the earliest. Upon exercise of an option, the Company would be entitled to an option exercise payment of $35 million, as well
as development and regulatory milestone payments ($320 million) and commercialization milestone payments ($500 million) and tiered, mid-single digit to mid-
teen percentage royalties on net sales of the applicable product. The royalties payable to the Company may be reduced under certain circumstances, including loss
of exclusivity, lack of patent protection or the specific nature of the compound included within the applicable product. Additionally, the Company would have
rights to co-fund certain development costs in order to obtain profit and loss sharing in Europe. So long as the Company elects to co-fund such development costs,
it will have a right to co-promote optioned products in Europe.

2) Accounting policies and statement of compliance

a) Basis of preparation

Consolidated financial statements of the Company for the years ended December 31, 2017, 2018 and 2019 (the “Consolidated Financial Statements”) have been
prepared under the responsibility of the management of the Company in accordance with the underlying assumptions of going concern as the Company’s loss-
making situation is explained by the innovative nature of the products developed, therefore involving a multi-year research and development phase.

The general accounting conventions were applied in compliance with the principle of prudence, in accordance with the underlying assumptions namely (i) going
concern, (ii) permanence of accounting methods from one year to the next and (iii) independence of financial years, and in conformity with the general rules for
the preparation and presentation of consolidated financial statements in accordance with IFRS, as defined below.

Except for share data and per share amounts, the Consolidated Financial Statements are presented in thousands of euro. Amounts are rounded up or down to the
nearest whole number for the calculation of certain financial data and other information contained in these accounts. Accordingly, the total amounts presented in
certain tables may not be the exact sum of the preceding figures

b) Statement of compliance

The Consolidated Financial Statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the
International Accounting Standard Board (“IASB”) and were approved and authorized for issuance by the Board of Directors of the Company on March 9, 2020.

Due to the listing of ordinary shares of the Company on Euronext Paris and in accordance with the European Union’s regulation No. 1606/2002 of July 19, 2002,
the Consolidated Financial Statements of the Company for the years ended December 31, 2017, 2018 and 2019 are also prepared in accordance with IFRS, as
adopted by the European Union (EU). For the years ended December 31, 2017, 2018 and 2019, all IFRS that the IASB had published and that are mandatory are
the same as those endorsed by the EU and mandatory in the EU. As a result, the Consolidated Financial Statements comply with International Financial Reporting
Standards as published by the IASB and as adopted by the EU.

IFRS include International Financial Reporting Standards (IFRS), International Accounting Standards (“IAS”), as well as the interpretations issued by the
Standing Interpretations Committee (“SIC”), and the International Financial Reporting Interpretations Committee (“IFRIC”). The main accounting methods used
to prepare the Consolidated Financial Statements are described below. These methods were used for all periods presented.

c) Recently issued accounting standards and interpretations

Application of the following new and amended standards was mandatory for the first time for the financial period beginning on January 1, 2018 and, as

such, they have been adopted by the Company:

•
•

IFRS 9, which supersedes IAS 39; and
IFRS 15, which supersedes IAS 11, IAS 18 and the corresponding interpretations (IFRIC 13, IFRIC 15, IFRIC 18 and SIC 31).

F-14

 
 
 
 
 
 
 
 
 
 
 
 
Application of the following new and amended standards is mandatory for the first time for the financial period beginning on January 1, 2019 and, as such,

they have been adopted by the Company:

•
•

•
•
•
•

IFRS 16 “Leases”, which supersedes IAS 17 and the corresponding interpretations (IFRIC 4, SIC 15 and SIC 27).
Amendments to IAS 19 “Employee benefits—Plan Amendment, Curtailment or Settlement”, mandatory for annual periods beginning on or after
January 1, 2019.
Amendments to IAS 28 regarding “Long-term interests in associates and Joint-Ventures”.
Amendments to IFRS 9 “Financial instruments—Prepayment features with negative compensation”.
IFRIC 23 “Uncertainty over income tax treatments”.
Annual improvements of the cycle 2015-2017 (amendments to IAS 12, IAS 23, IFRS 3 and IFRS 11).

Those standards and interpretations have no impact on the Consolidated Financial statements, except as noted below following IFRS 9, IFRS 15 and IFRS

16 application.

New standards, amendments to existing standards and subsequent interpretations have been published but are not applicable in 2019.

•
•
•

•

IFRS 17 "Insurance Contracts", published on May 18, 2017 and which will come into force on January 1, 2021.
Amendment to IFRS 3 "Definition of a business", published on October 22, 2018 and applicable from January 1, 2020.
Amendments to IAS 1 and IAS 8 relating to the modification of the definition of the term “significant”, published on October 31, 2018 and applicable
on January 1, 2020.
Modification of references to the Conceptual Framework in IFRS standards, applicable from January 1, 2020.

The Company has not early adopted these new accounting standards, amendments and interpretations. These new accounting standards, amendments and

interpretations will not have significant impact on our financial statements.

d) Adoption of IFRS 15

IFRS 15 Revenue from contracts with customers, or IFRS 15, which supersedes IAS 11 Construction contracts, or IAS 11, and IAS 18 Revenue, or IAS 18,

came into effect on January 1, 2018. The amended accounting policy applied to revenue is presented in Note 2.ss.

The Company decided to apply the modified retrospective approach without any of the practical expedients allowed by IFRS 15. According to this
approach, the comparative information is not restated and the cumulative impact of the first application is presented as an adjustment of the opening equity of the
year of first application. The modified retrospective approach does not present comparative information, but requires a comparison for the first application year of
each financial statement line item affected by the application of this standard as compared to IAS 11, IAS 18 and related interpretations that were in effect before
the change. This comparison is presented below.

F-15

 
 
 
 
 
 
 
 
The impact of the adoption of IFRS 15 is limited to the accounting treatment of the contributions paid by the Company pursuant to its co-financing under

the collaboration agreement with AstraZeneca related to monalizumab. Until December 31, 2017, under IAS 18, the Company’s co-financing share of R&D
expenses incurred by AstraZeneca were recognized as R&D expenses.

In the context of the collaboration agreement with AstraZeneca, the Company and AstraZeneca make quarterly-cost sharing payments to one another to

ensure that each party co-finances the R&D performed by AstraZeneca. Consequently, under IFRS 15, amounts due to the partner:

•

•

Are no longer recognized as R&D expenses, but are recorded as a reduction of the transaction price recorded as revenue following the identified
performance obligation under the collaboration agreement; and
Are classified in collaboration liability in the consolidated statement of financial position (instead of a classification in deferred revenue under IAS
18).

When a collaboration liability is denominated in a foreign currency, which is the case in the context of this AstraZeneca agreement, it is translated at each

reporting date with the appropriate exchange rate, resulting in foreign exchange gains or losses recorded in the consolidated statement of income (loss).

Application of IFRS 15 generated a deferred tax liability of €3,098 thousand as of January 1, 2018. The Company recorded a deferred tax asset equaling the

amount of deferred tax liability as of January 1, 2018 as a result of tax losses carryforward.

The impact of the first adoption of IFRS 15 on the statement of financial position and the consolidated statement of income (loss) as of January 1, 2018 are

presented below:

e) Adoption of IFRS 9

IFRS 9 Financial instruments, or IFRS 9, which supersedes IAS 39 Financial instruments: recognition and measurement, or IAS 39, came into effect on

January 1, 2018. IFRS 9 defines new principles covering the classification and measurement of financial instruments, the recognition of impairment provisions for
credit risk on financial assets and hedge accounting. The Company has applied IFRS 9 as of January 1, 2018 by recording the cumulative impact in opening equity
at this transition date.

Regarding financial instruments, IFRS 9 requires, for non-derivative financial assets, a change of name of the sub-categories of financial assets without,

however, modifying the valuation principles of these assets, which remain either at fair value or amortized cost. The valuation models used by the Company
remain unchanged.

The modification of the impairment principles for financial assets measured at amortized cost, which now consists of adopting an approach based on
expected losses, in practice has resulted in the Company not recognizing impairment and mainly impacts trade receivables, which were nil as of January 1, 2018.

The only impact of IFRS 9 on the financial statements of the Company concerns the recognition of the variance in fair value of the mutual funds. Under IAS

39, the variance in fair value of these financial assets was recognized in other comprehensive income. Under IFRS 9, it will be recognized in the statement of
income. Following the application of the standard, the impact on the opening statement of financial position is a reclassification from the cumulated
comprehensive income to retained earnings in an amount of €653 thousand.

The amended accounting policy applied to financial instruments is presented in Note 2.j.

f) Adoption of IFRS 16

IFRS 16 was issued in January 2016 and it replaces IAS 17—Leases, IFRIC 4 “Determining whether an Arrangement contains a Lease”, SIC-15 “Operating

Leases-Incentives” and SIC-27 “Evaluating the Substance of Transactions Involving the Legal Form of a Lease.” IFRS 16 sets out the principles for the
recognition, measurement, presentation and disclosure of leases and requires lessees to account for all leases under a single on-balance sheet model similar to the
accounting for finance leases under IAS 17. The standard includes two recognition exemptions for lessees—leases of “low-value” assets (e.g., personal computers)
and short-term leases (including leases with a lease term of 12 months or less). At the commencement date of a lease, a lessee recognizes a liability to make lease
payments, or the lease liability, and an asset representing the right to use the underlying asset during the lease term, or the right-of-use asset. Lessees are required
to separately recognize the interest expense on the lease liability and the depreciation expense on the right-of-use asset. The change in presentation of operating
lease expenses results in a corresponding increase in cash flows from operating activities and a decrease in cash flows from financing activities.

F-18

 
 
 
 
 
 
 
According to the new standard, the Company determined the lease term including any lessee’s extension or termination option that is deemed reasonably

certain. The assessment of such options was performed at the commencement of a lease and required judgment by the management. Measuring the lease liability
at the present value of the remaining lease payments required using an appropriate discount rate in accordance with IFRS 16. The discount rate is the interest rate
implicit in the lease or if that cannot be determined, the incremental borrowing rate at the date of the lease commencement. The incremental borrowing rate can
have a significant impact on the net present value of the right-of use asset and lease liability recognized and requires judgement.

Lessees remeasure the lease liability upon the occurrence of certain events (e.g., a change in the lease term, a change in future lease payments resulting from

a change in an index or rate used to determine those payments). The lessee generally recognizes the amount of the remeasurement of the lease liability as an
adjustment to the right-of-use asset.

Following analysis carried out by the Company, the contracts impacted by this new standard mainly relate to the rental of premises.

With respect to the transition method, the Company has opted for the modified retrospective approach to contracts previously reported as leases under IAS
17 or IFRIC 4, and, therefore, will only recognize leases on its statement of financial position as of January 1, 2019. Accordingly, comparative information is not
restated and the cumulative effect of initially applying IFRS 16 is presented as an adjustment to retained earnings. As of January 1, 2019, the right of use is
recognized as assets for their net value (as if IFRS 16 had always been applied) and the present value of the remaining payments is recognized as a liability.

The Company applies the following practical expedients as allowed by IFRS 16:

•
•
•

•

Apply a single discount rate to the assets with similar characteristics;
Use of hindsight in determining the lease term where the contract contains options to extend or terminate the lease;
Exclude lease contracts for which the lease term ends within 12 months as of the date of initial application, thus considering them short-term lease
contracts; and
Exclude leases of assets with a replacement value of less than approximately €5 thousand.

The impact of the first adoption of IFRS 16 on the statement of financial position as of January 1, 2019 is presented below:

g) Change in accounting policies

Except for the adoption of IFRS 9 and IFRS 15 as of January 1, 2018 and the adoption of IFRS 16 as of January 2019, there has been no change in

accounting policies for any of the years presented.

h) Translation of transactions denominated in foreign currency

Pursuant to IAS 21 The effects of changes in foreign exchange rates, transactions performed by consolidated entities in currencies other than their functional

currency are translated at the prevailing exchange rate on the transaction date.

F-20

 
 
   
   
   
   
   
   
 
 
 
 
 
Trade receivables and payables and liabilities denominated in a currency other than the functional currency are translated at the period-end exchange rate.

Unrealized gains and losses arising from translation are recognized in net operating income.

Foreign exchange gains and losses arising from the translation of inter-Group transactions or receivables or payables denominated in currencies other than

the functional currency of the entity are recognized in the line “net financial income (loss)” of the consolidated statements of income (loss).

Foreign currency transactions are translated into the presentation currency using the following exchange rates:

The Group applies IFRS 10 Consolidated financial statements. IFRS 10 presents a single consolidation model identifying control as the criteria for
consolidating an entity. An investor controls an investee if it has the power over the entity, is exposed or has rights to variable returns from its involvement with
the entity and has the ability to use its power over the entity to affect the amount of the investor’s returns. Subsidiaries are entities over which the Company
exercises control. They are fully consolidated from the date the Group obtains control and are deconsolidated from the date the Group ceases to exercise control.
Intercompany balances and transactions are eliminated.

j) Financial instruments

Financial assets

Financial assets are initially measured at fair value plus directly attributable transaction costs in the case of instruments not measured at fair value through
profit or loss. Directly attributable transaction costs of financial assets measured at fair value through profit or loss are recorded in the consolidated statement of
income (loss).

Under IFRS 9, financial assets are classified in the following three categories:

•
•
•

Financial assets at amortized cost;
Financial assets at fair value through other comprehensive income (“FVOCI”); and
Financial assets at fair value through profit or loss.

The classification of financial assets depends on:

•
•

The characteristics of the contractual cash flows of the financial assets; and
The business model that the entity follows for the management of the financial asset.

Financial assets at amortized cost

Financial assets are measured at amortized cost when (i) they are not designated as financial assets at fair value through profit or loss, (ii) they are held
within a business model whose objective is to hold assets in order to collect contractual cash flows and (iii) they give rise to cash flows that are solely payments of
principal and interest on the principal amount outstanding (“SPPI” criterion). They are subsequently measured at amortized cost, determined using the effective
interest method (“EIR”), less any expected impairment losses in relation to the credit risk. Interest income, exchange gains and losses, impairment losses and gains
and losses arising on derecognition are all recorded in the consolidated statement of income (loss).

F-21

 
 
 
 
 
   
   
 
 
   
   
   
   
   
 
   
 
 
 
 
 
 
 
 
 
 
 
This category primarily includes trade receivables, as well as other loans and receivables. Long-term loans and receivables that are not interest-bearing or

that bear interest at a below-market rate are discounted when the amounts involved are material.

Financial assets at fair value through other comprehensive income

Financial assets at fair value through other comprehensive income is mainly comprised is composed of debt instruments whose contractual cash flows
represent payments of interest or repayments of principal, and which are managed with a view to collecting cash flows and selling the asset. Gains and losses
arising from changes in fair value are recognized in equity within the statement of comprehensive income in the period in which they occur. When such assets are
derecognized, the cumulative gains and losses previously recognized in equity are reclassified to profit or loss for the period within the line items Financial
income or Financial expenses. The Company did not hold this type of instrument as of January 1, 2019 or as of December 31, 2019.

Financial assets at fair value through profit or loss

Financial assets at fair value through profit or loss is comprised of:

•
•

financial assets that are not part of the above categories; and
instruments that management has designated as “fair value through profit or loss” on initial recognition.

Gains and losses arising from changes in fair value are recognized in profit or loss within the line items financial income or financial expenses.

Impairment of financial assets measured at amortized cost

The main assets involved are trade receivables and others. Trade receivables are recognized when the Company has an unconditional right to payment by the

customer. Impairment losses on trade receivables and others are estimated using the expected loss method, in order to take account of the risk of payment default
throughout the lifetime of the receivables. The expected credit loss is estimated collectively for all accounts receivable at each reporting date using an average
expected loss rate, determined primarily on the basis of historical credit loss rates. However, that average expected loss rate may be adjusted if there are
indications of a likely significant increase in credit risk. If a receivable is subject to a known credit risk, a specific impairment loss is recognized for that
receivable. The amount of expected losses is recognized in the balance sheet as a reduction in the gross amount of accounts receivable. Impairment losses on
accounts receivable are recognized within Operating expenses in the consolidated statement of income (loss).

Financial liabilities

Financial liabilities comprise deferred revenue, collaboration liabilities, loans and trade and other payables.

F-22

 
 
 
 
 
 
 
 
 
 
Financial liabilities are initially recognized on the transaction date, which is the date that the Company becomes a party to the contractual provisions of the

instrument. They are derecognized when the Company’s contractual obligations are discharged, cancelled or expire.

Loans are initially measured at fair value of the consideration received, net of directly attributable transaction costs. Subsequently, they are measured at

amortized cost using the EIR method. All costs related to the issuance of loans, and all differences between the issuance proceeds net of transaction costs and the
value on redemption, are recognized within financial expenses in the consolidated statement of income (loss) over the term of the debt using the EIR method.

Other financial liabilities include trade accounts payable, which are measured at fair value (which in most cases equates to face value) on initial recognition,

and subsequently at amortized cost.

Cash and cash equivalents

Cash equivalents are short-term, highly liquid investments, that are readily convertible to known amounts of cash and which are subject to an insignificant
risk of changes in value. Cash and cash equivalents comprise the cash that is held at the bank and petty cash as well as the short-term fixed deposits for which the
maturity is less than three months.

For the purpose of establishing the statement of cash flows, cash and cash equivalents include cash in hand, demand deposits and short fixed-term deposits

with banks and short-term highly liquid investments with original maturities of three months or less, net of bank overdrafts.

Cash and cash equivalents are initially recognized at their purchase costs on the transaction date, and are subsequently measured at fair value. Changes in

fair value are recognized in profit or loss.

Fair value of financial instruments

Under IFRS 13 Fair value measurement and IFRS 7 Financial instruments: disclosures, or IFRS 7, fair value measurements must be classified using a

hierarchy based on the inputs used to measure the fair value of the instrument. This hierarchy has three levels:

•
•

•

level 1: fair value calculated using quoted prices in an active market for identical assets and liabilities;
level 2: fair value calculated using valuation techniques based on observable market data such as prices of similar assets and liabilities or parameters
quoted in an active market; and
level 3: fair value calculated using valuation techniques based wholly or partly on unobservable inputs such as prices in an inactive market or a
valuation based on multiples for unlisted securities.

k) Intangible assets

Research and development (R&D) expenses

In accordance with IAS 38 Intangible assets, or IAS 38, expenses on research activities are recognized as an expense in the period in which it is incurred.

F-23

 
 
 
 
 
 
 
 
 
 
 
 
 
An internally generated intangible asset arising from the Company’s development activities is recognized only if all of the following conditions are met:

•
•
•
•
•
•

Technically feasible to complete the intangible asset so that it will be available for use or sale;
The Company has the intention to complete the intangible assets and use or sell it;
The Company has the ability to use or sell the intangible assets;
The intangible asset will generate probable future economic benefits, or indicate the existence of a market;
Adequate technical, financial and other resources to complete the development are available; and
The Company is able to measure reliably the expenditure attributable to the intangible asset during its development.

Because of the risks and uncertainties related to regulatory approval, the R&D process and the availability of technical, financial and human resources

necessary to complete the development phases of the product candidates, the six criteria for capitalization are usually considered not to have been met until the
product candidate has obtained marketing approval from the regulatory authorities. Consequently, internally generated development expenses arising before
marketing approval has been obtained, mainly the cost of clinical trials, are generally expensed as incurred within Research and development expenses.

However, some clinical trials, for example those undertaken to obtain a geographical extension for a molecule that has already obtained marketing approval

in a major market, may in certain circumstances meet the six capitalization criteria under IAS 38, in which case the related expenses are recognized as an
intangible asset. These related costs are capitalized when they are incurred and amortized on a straight line basis over their useful lives beginning when marketing
approval is obtained.

Licenses

Payments for separately acquired research and development are capitalized within “Other intangible assets” provided that they meet the definition of an

intangible asset: a resource that is (i) controlled by the Group, (ii) expected to provide future economic benefits for the Group and (iii) identifiable (i.e. it is either
separable or arises from contractual or legal rights).

In accordance with paragraph 25 of IAS 38, the first recognition criterion, relating to the likelihood of future economic benefits generated by the intangible

asset, is presumed to be achieved for research and development activities when they are acquired separately.

In this context, amounts paid to third parties in the form of initial payments or milestone payments relating to product candidates that have not yet obtained

a regulatory approval are recognized as intangible assets. These rights are amortized on a straight-line basis:

(i)
(ii)

after obtaining the regulatory approval, over their useful life; or
after entering in an out-license collaboration agreement with a third-party partner, over their estimated useful life. This estimated useful life takes into
consideration the period of protection of the out-licensed exclusivity rights and the anticipated period over which the Company will receive the
economic benefits of the asset.

Unamortized rights (before marketing authorization) are subject to impairment tests in accordance with the method defined in Note 6.

When intangible assets acquired separately are acquired through variable or conditional payments, these payments are recognized as an increase of the

carrying amount of the intangible asset when they become due. Royalties due by the Company related to acquired licenses are recognized as operating expenses
when the Company recognizes sales subject to royalties.

F-24

 
 
 
 
 
 
 
 
 
 
Other intangible assets

Other intangible assets consist of acquired software. Costs related to the acquisition of software licenses are recognized as assets based on the costs incurred

to acquire and set up the related software. Software is amortized using the straight-line method over a period of one to three years depending on the anticipated
period of use.

l) Property and equipment

Property and equipment are carried at acquisition cost. Major renewals and improvements are capitalized while repairs and maintenance are expensed as

incurred.

Property and equipment are depreciated over their estimated useful lives using the straight-line depreciation method. Leasehold improvements are

depreciated over the life of the improvement or the remaining lease term, whichever is shorter.

The headquarters of the Company was split into several components (e.g., foundations, structure, electricity, heating and ventilation systems) which are

depreciated over different useful lives according to the anticipated useful life of these elements.

Depreciation periods are as follows:

Buildings and improvements on buildings (years)
Installations (years)
Technical installations and equipment (years)
Equipment and office furniture (years)
Computers and IT equipment (years)

m) Impairment of intangible assets, property, and equipment,

to
to

The Group assesses at the end of each reporting period whether there is an indication that intangible assets, property and equipment may be impaired. If any

indication exists, the Group estimates the recoverable amount of the related asset.

Whether or not there is any indication of impairment, intangible assets not yet available for use are tested for impairment annually by comparing their

carrying amount with their recoverable amount.

Pursuant to IAS 36—Impairment of Assets, criteria for assessing indication of loss in value may notably include performance levels lower than forecast, a

significant change in market data or the regulatory environment, or obsolescence or physical damage of the asset not included in the amortization/depreciation
schedule. The recognition of an impairment loss alters the amortizable/depreciable amount and potentially, the amortization/depreciation schedule of the relevant
asset.

Impairment losses on intangible assets, property and equipment shall be reversed subsequently if the impairment loss no longer exists or has decreased. In

such case, the recoverable amount of the asset is to be determined again so that the reversal can be quantified. The asset value after reversal of the impairment loss
may not exceed the carrying amount net of depreciation/amortization that would have been recognized if no impairment loss had been recognized in prior periods.

The Group does not have any intangible assets with an indefinite useful life. However, as explained in Note 2.kk, the Group recognized intangible assets in

progress, which will be amortized once marketing authorization is received.

n) Employee benefits

Long-term pension benefits

Company employees are entitled to pension benefits required by French law:

•
•

Pension benefit, paid by the Company upon retirement (i.e. defined benefit plan); and
Pension payments from social security entities, financed by contributions from businesses and employees (i.e. defined contribution plan”).

In addition, the Company has implemented an additional, non-mandatory, pension plan (“Article 83”), initially for the benefit of executives only. This plan

was extended to the non-executive employees starting on January 1, 2014. This plan meets the definition of defined contribution plan and is financed through a
contribution that corresponds to 2.2% of the employee’s annual wage, with the Company paying 1.4% and the employee paying 0.8%.

For the defined benefit plan, the costs of the pension benefit are estimated using the “projected unit credit” method. According to this method, the pension
cost is accounted for in the consolidated statement of income (loss), so that it is distributed uniformly over the term of the services of the employees. The pension
benefit commitments are valued using the actual present value of estimated future payments, adopting the rate of interest of long-term bonds in the private sector
(i.e. Euro zone AA or higher rated corporate bonds + 10 years). The difference between the amount of the provision at the beginning of a period and at the close of
that period is recognized in the consolidated statement of income (loss) for the portion representing the costs of services rendered and the net interest costs, and
through other comprehensive income for the portion representing the actuarial gains and losses. The Company’s commitments under the defined benefit plan are
not covered by any plan assets.

Payments made by the Company for defined contribution plans are accounted for as expenses in the consolidated statement of income (loss) in the period in

which they are incurred.

Other long-term benefits

The Company pays seniority bonuses to employees reaching 10, 15 and 20 years of seniority. These bonuses represent long-term employee benefits. Under

IAS 19R “Employee benefits”, they are recording as a defined benefit obligation in the consolidated statement of financial position, but their remeasurements is
not recognized in the consolidated statement of other comprehensive income (loss).

Other short-term benefits

An accrued expense is recorded for the amount the Company expects to pay its eligible employees in relation to services rendered during the reporting

period (actual legal or implicit obligation to make to these payments on a short-term basis).

o) Leases

The Company assesses whether a contract is or contains a lease, at inception of the contract. The Company recognizes a right-of-use asset and a

corresponding lease liability with respect to all lease arrangements in which it is the lessee, except for short-term leases (defined as leases with a lease term of 12
months or less) and leases of low value assets (such as tablets and personal computers, small items of office furniture and telephones). For these leases, the
Company recognizes the lease payments as an operating expense on a straight-line basis over the term of the lease unless another systematic basis is more
representative of the time pattern in which economic benefits from the leased assets are consumed.

F-26

 
 
 
 
 
 
 
 
 
 
 
 
The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted by using the rate
implicit in the lease. If this rate cannot be readily determined, the Company uses its incremental borrowing rate. Lease payments included in the measurement of
the lease liability comprise:

•
•
•
•
•

fixed lease payments (including in-substance fixed payments), less any lease incentives receivable;
variable lease payments that depend on an index or rate, initially measured using the index or rate at the commencement date;
the amount expected to be payable by the lessee under residual value guarantees;
the exercise price of purchase options, if the lessee is reasonably certain to exercise the options; and
payment of penalties for terminating the lease, if the lease term reflects the exercise of an option to terminate the lease.

The lease liability is included in the financial liabilities in the consolidated statement of financial position and is subsequently measured by increasing the
carrying amount to reflect interest on the lease liability (using the effective interest method) and by reducing the carrying amount to reflect the lease payments
made.

The right-of-use assets comprise the initial measurement of the corresponding lease liability, lease payments made at or before the commencement day, less

any lease incentives received and any initial direct costs. They are subsequently measured at cost less accumulated depreciation and impairment losses.

Whenever the Company incurs an obligation for costs to dismantle and remove a leased asset, restore the site on which it is located or restore the underlying
asset to the condition required by the terms and conditions of the lease, a provision is recognized and measured under IAS 37. To the extent that the costs relate to
a right-of-use asset, the costs are included in the related right-of-use asset, unless those costs are incurred to produce inventories.

Right-of-use assets are depreciated over the shorter period of lease term and useful life of the underlying asset. If a lease transfers ownership of the
underlying asset or the cost of the right-of-use asset reflects that the Company expects to exercise a purchase option, the related right-of-use asset is depreciated
over the useful life of the underlying asset. The depreciation starts at the commencement date of the lease.

The right-of-use assets are included in the property and equipment line item in the consolidated statement of financial position.

The Company applies IAS 36 to determine whether a right-of-use asset is impaired and accounts for any identified impairment loss.

p) Provisions

In the course of its business, the Company could be exposed to certain risks and litigations, notably in relation to contractual arrangements. Provisions are

recognized when the Company has a present legal or constructive obligation as a result of past events, it is probable that the Company is subject to a release of
outflow representatives of economic benefits to settle the obligation and a reliable estimate of the amount of the obligation can be made. Management of the
Company estimates the probability and the expected amount of a cash outflow associated with risks, together with the other information to be provided on possible
liabilities. Where the Company expects a provision to be reimbursed, for example under an insurance contract, the reimbursement is recognized as a separate asset
but only when the reimbursement is certain.

F-27

 
 
 
 
 
 
 
 
 
q) Capital

Ordinary shares are classified in shareholders’ equity. Costs associated with the issuance of new shares are directly accounted for in shareholders’ equity in

diminution of issuance premium.

The Company’s own shares bought in the context of a brokering/liquidity agreement are presented as a reduction in shareholders’ equity until their

cancellation, their reissuance or their disposal.

r) Share-based compensation

Since its inception, the Company has established several plans for compensation paid in equity instruments in the form of free shares (“Attributions
gratuites d’actions,” or “AGA”), free preferred shares convertible into ordinary shares (“Attributions gratuites d’actions de préférence convertibles en actions
ordinaires,” or “AGAP”), free performance shares (“Attributions gratuites d’actions de performance,” or “AGA Perf”), share subscription warrants (“Bons de
souscription d’actions,” or “BSA”), redeemable share subscription warrants (“Bons de Souscription et/ou d’Acquisition d’Actions Remboursables,” or “BSAAR”),
granted to its employees, executives, members of the Executive Board and scientific consultants.

Pursuant to IFRS 2—Share-based Payment, these awards are measured at their fair value on the date of grant. The fair value is calculated with the most

relevant formula regarding the conditions and the settlement of each plan.

For share-based compensation granted to employees, executives, members of the Executive Board and scientific consultants, the Company uses the Black-

Scholes and Monte Carlo approach pricing models to determine the fair value of the share-based compensation. For scientific consultants providing similar
services, as the Company cannot estimate reliably the fair value of the goods or services received, it measures the value of share-based compensation and the
corresponding increase in equity, indirectly, by reference to the fair value of the equity instruments granted also using the Black-Scholes option pricing model. The
fair value of free shares included in the model is determined using the value of the shares at the time of their distribution.

In calculating the fair value of share-based compensation, the Company also considers the vesting period and the employee turnover weighted average

probability as described in Note 14. Other assumptions used are also detailed in Note 14.

The Company recognizes the fair value of these awards as a share-based compensation expense over the period in which the related services are received

with a corresponding increase in shareholders’ equity. Share-based compensation is recognized using the straight-line method. The share compensation expense is
based on awards ultimately expected to vest and is reduced by expected forfeitures.

F-28

 
 
 
 
 
 
 
 
s) Revenue

Revenue from collaboration and license agreements

To date, the Company’s revenue results primarily from payments received in relation to research, collaboration and licensing agreements signed with

pharmaceutical companies. These contracts generally provide for components such as:

•
•
•

•
•

non-refundable upfront payments upon signature;
payments for the exercise of the option to acquire licenses of drug candidates;
milestones payments triggered following stages of development (scientific results obtained by the Company or by the partner, obtaining regulatory
marketing approvals);
payments related to the Company’s R&D activities;
payments triggered by the start of the commercialization of products resulting from development work or by crossing cumulative thresholds of
product sales, as well as the allocation of royalties on future sales of products or a sharing of profits on sales.

Under collaboration and license agreements, the Company may promise its partners licenses on intellectual property, as well as research and development

services. According to IFRS 15, the Company has to determine if the promises included in the contract are distinct (therefore recognized separately as revenue) or
if they have to be combined as a single performance obligation.

When promises in a collaboration and license agreement are considered as a single performance obligation, the Company has to determine if the combined

performance obligation is satisfied over time or at point in time. If the combined performance obligation is satisfied over time, revenue recognition is based on the
percentage of completion of the costs to be incurred. Non-refundable initial payments are deferred and recognized as revenue during the period the Company is
engaged to deliver services to the customer on the basis of the corresponding costs.

When promises in a collaboration and license agreement are considered as separate performance obligations, revenue is allocated to each obligation
proportionally to its transaction price, which corresponds to a price each performance obligation would have been sold in the context of a separate transaction.

In accordance with IFRS 15, variable considerations cannot be included in the estimated transaction price as long as it not highly probable that the related

revenue will not be reversed in the future. According to the level of uncertainty relating to the results of preclinical and clinical trials and the decisions relating to
the regulatory approvals, variable considerations depending on these events are excluded from the transaction price as long as the trigger event is not highly
probable. When the trigger event occurs, the corresponding milestone is added to the transaction price. Such adjustments are recorded on a cumulative catch-up
basis, which would affect revenues and net income (loss) in the period of adjustment.

Revenues based on royalties, completion of commercialization steps or co-sharing profit from sales are recognized when the corresponding sales of products

are carried out by the partner.

When a collaboration contract grants a partner an option to acquire a licensed intellectual property (“IP”), the Company determines the date of the transfer

of control over the licensed IP. Depending on the Company analysis, revenue related to the option fee will be recognized (i) when control over the licensed IP
transfers (payment related to the exercise of the option being therefore considered as a variable consideration), or, (ii) deferred until the exercise of the option or its
expiration period.

F-29

 
 
 
 
 
 
 
 
 
When an agreement only promises development services, the Company will recognize the related revenue when the costs are incurred.

Up-front and milestones payments and fees are recorded as deferred revenue upon receipt or when due, and may require deferral of revenue recognition to a

future period until the Company performs its obligations under these arrangements. Amounts due by the Company in relation to cost-sharing are recorded as
collaboration liability. Amounts payable to the Company are recorded as accounts receivable when the Company’s right to consideration is unconditional.

See Note 13 for accounting description of significant agreements.

t) Net income (expenses) from distribution agreements

When product sales are made by a partner in the context of collaboration or transition agreements, the Company must determine whether it acts as agent or
principal. A party is recognized as a principal when it has the ability to conduct the use of the products and to obtain all the residual economic benefits previously
to the transfer of the control of the products to the customers. If the Company is a principal, sales are recognized as revenue. If the Company is an agent, it
recognizes as a gain or a loss, the part of the revenue it is entitled to, which is the case under the agreement with AstraZeneca in relation to Lumoxiti (see
Note 15). Therefore, income (loss) under the agreement are recognized in the statement of income (loss) on the line item “Net income (loss) from distribution
agreements”.

u) Government financing for research expenditures

Research tax credit

The research tax credit (Crédit d’Impôt Recherche) (the “Research Tax Credit” or “CIR”) granted by the French tax authorities in order to encourage
Companies to conduct technical and scientific research. Companies that can justify that these expenses meet the required criteria receive such grants in the form of
a refundable tax credit that can be used for the payment of taxes due for the period in which the expense was incurred and for the next three years. These grants are
presented under other income, in “government financing for research expenditures” line item in the consolidated statements of income (loss), as soon as these
eligible expenses were conducted.

The Company has benefited from a Research Tax Credit since its inception.

The Company received the reimbursements of the Research Tax Credits for the year 2017 and 2018, during the year 2018 and 2019 respectively. These

reimbursements were made under the European Community tax rules for small and medium sized enterprises (“SME”) in compliance with the applicable
regulations in effect. Only companies that meet the definition of SME according to European Union criteria are eligible for early reimbursement of their CIR.
Management ensured that the Company was a SME according to European Union criteria as of December 31, 2017 and 2019, and can therefore benefit from this
early reimbursement. As of December 31, 2019, the Company no longer meets the eligibility criteria for this status. Thus, the CIR for the years 2019 and after will
represent a receivable against the French Treasury which will in principle be offset against the French corporate income tax due by the company with respect to
the three following years. The remaining portion of tax credit not being offset upon expiry of such a period may then be refunded to the Company.

The CIR is presented under other income, in “government financing for research expenditures” line item in the consolidated statements of income (loss) as it

meets the definition of government grant as defined in IAS 20 Accounting for government grants and disclosure of government assistance.

F-30

 
 
 
 
 
 
 
 
 
 
Subsidies

Government grants are recognized when there is a reasonable assurance that:

•
•

The Company will comply with the conditions attached to the grants; and that
The grants will be received.

A government grant that becomes receivable as compensation for expenses or losses already incurred, or for the purpose of providing immediate financial

support to the Company with no future related costs, is recognized as other income of the period in which it becomes receivable.

Government grants to subsidize capital expenditures are presented in the statement of financial position as deferred income and are recognized as income on

a straight line basis over the useful life of those assets that have been financed through the grants.

A non-repayable loan from the government is treated as a government grant when there is a reasonable assurance that the Company will meet the terms for

non-repayment of the loan. When there is no such assurance, the loan is recorded as a liability under borrowings.

v) Income tax

Deferred income tax is provided in full, using the liability method, on temporary differences arising between the tax bases of assets and liabilities and their
carrying amounts in the financial statements. Main temporary differences are generally associated with the depreciation of property and equipment, provisions for
pension benefits and tax losses carried forward and also with the deferred tax liabilities / assets generated by the application of IFRS 15 (see Note 2.dd “Adoption
of IFRS 15”). Currently enacted tax rates are used in the determination of deferred income tax.

Deferred tax assets are recognized to the extent that it is probable that future taxable profit will be available against which the temporary differences can be

utilized. Due to Company’s early stage of development, it is not probable that future taxable profit will be available against which the unused tax losses can be
utilized. As a consequence, deferred tax assets are recognized up to deferred tax liabilities.

w) Earnings (loss) per share

In accordance with IAS 33 Earnings per share, basic income (loss) per share is calculated by dividing the income (loss) attributable to equity holders of the

Group by the weighted average number of outstanding shares for the period.

Diluted income (loss) per share is measured by dividing the income (loss) attributable to holders of equity and dilutive instruments by the weighted average

number of outstanding shares and dilutive instruments for the period.

If in the calculation of diluted income (loss) per share, instruments giving deferred rights to capital such as warrants generates an antidilutive effect, then

these instruments are not taken into account.

x) Other comprehensive income

Items of income and expenses for the period that are recognized directly in equity are presented under “other comprehensive income.” The items mainly

include :

• Foreign currency translation gain (loss); and
• Actuarial gains and (losses) related to defined benefit obligations.

F-31

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
y) Segment information

For internal reporting purposes, and in order to comply with IFRS 8 Operating segments, the Company performed an analysis of operating segments.
Following this analysis, the Company considers that it operates within a single operating segment being the R&D of pharmaceutical products in order to market
them in the future. All R&D activities of the Company are located in France. Key decision makers (the executive committee of the Company) monitor the
Company’s performance based on the cash consumption of its activities. For these reasons, the Management of the Group considers it not appropriate to set up
separate business segments in its internal reporting.

In 2017 and 2018 and 2019, revenue was entirely generated by one customer.

z) Critical accounting estimates and assumptions

The preparation of the consolidated financial statements under IFRS requires management to make estimates, assumptions and judgments that affect the

reported amounts of assets, liabilities, income and expenses during the reporting period. The Company bases estimates and assumptions on historical experience
when available and on various factors that it believes to be reasonable under the circumstances. The Company’s actual results may differ from these estimates
under different assumptions or conditions.

These estimates and judgments involve mainly:

•

•

•

the accounting for collaboration and licensing agreements: the revenue results primarily from payments based on several components (e.g.,
upfront payments, milestone payments) received in relation to research, collaboration and licensing agreements signed with pharmaceutical or other
companies. When the Company is committed to perform R&D services, revenue is spread over the period the Company is engaged to deliver these
services, more particularly on the basis of the Company’s inputs to the satisfaction of a performance obligation relative to the total expected inputs to
the satisfaction of that performance obligation.

Milestone payments are dependent upon the achievement of certain scientific, regulatory, or commercial milestones. These variable payments are
recognized when the triggering event has occurred, there are no further contingencies or services to be provided with respect to that event, and the
counterparty has no right to refund of the payment.

The changes in estimate regarding the completion of the works and the variable consideration relating to the contracts signed with customers are
described in Note 13.

the measurement of the subcontracting costs relating to the clinical trial costs: the completion of the subcontracting costs related to clinical trials
is based on two allocation keys: (i) time, for the services defined as permanent and linear: completion is then measured based on total duration of the
clinical trial, and/or (ii) the number of patients visits for services provided to patients: completion is then measured based on the projected number of
patients visits for the clinical trial, and/or (iii) if the Company is not sponsor of the trial, the criteria number of patients visits is replaced by the criteria
number of patients: completion is then measured based on the projected number of patients for the clinical trial. For each clinical trial, these allocation
keys are applied to the budget of the clinical trial.

the estimation of shared development costs and transition costs under the 2015 AstraZeneca monalizumab agreement and the AstraZeneca
Lumoxiti in-licensing agreement: quarterly invoices submitted by AstraZeneca under these agreements are based on estimates made by AstraZeneca
management as a result of its accounting work. This implies estimates from AstraZeneca regarding the advancement of their clinical costs.
AstraZeneca submits to the Company an update of their budgets which is reviewed by the Company in order to identify potential deviations. These
estimates of shared development costs and transition costs have a significant impact on the Company’s operating income (loss), trade payables and
collaboration liabilities.

F-32

 
 
 
 
 
 
 
 
 
 
•

•

•

the measurement of the fair value of warrants: the measurement of the fair value of warrants granted to employees, non-employee members of the
Executive Board, scientific consultants, determined on the basis of Black-Scholes option and Monte Carlo approach pricing models; these models
require the use by the Company of certain calculation assumptions such as the expected volatility of the underlying share or the employee turnover
weighted average rate.

the estimate of the recoverable amount of the acquired and under progress licenses: impairment tests are performed on a yearly basis for the
intangible assets which are not amortized (such as intangible assets in progress). Amortizable intangible assets are tested for impairment when there is
an indicator of impairment. Impairment tests involve comparing the recoverable amount of the licenses to their net book value. The recoverable
amount of an asset is the higher of its fair value less costs to sell and its value in use. If the carrying amount of any asset is below its recoverable
amount, an impairment loss is recognized to reduce the carrying amount to the recoverable amount. The main assumptions used for the impairment
test include (a) the amount of cash flows that are set on the basis of the development and commercialization plans and budgets approved by
Management, (b) assumptions related to the achievement of the clinical trials and the launch of the commercialization, (c) the discount rate,
(d) assumptions on risk related to the development and (e) for the commercialization, selling price and volume of sales, Any change in these
assumptions could lead to the recognition of an impairment charge that could have a significant impact on the Company’s consolidated financial
statements.

the estimate of the useful life of the acquired licenses: intangible assets are amortized on a straight line basis over their anticipated useful life. The
estimated useful life is the period over which the asset provides future economic benefits. It is estimated by management and is regularly revised by
taking into consideration the period of development over which it expects to receive economic benefits such as collaboration revenues, royalties,
product of sales, etc. However, given the uncertainty surrounding the duration of the R&D activities for the programs in development and their
likelihood to generate future economic benefits to the Company, the estimated useful life of the rights related to these programs is rarely longer than
the actual development phase of the product candidate. When a program is in commercialization phases, the useful life takes into account the
protection of the exclusivity rights and the anticipated period of commercialization without taking into account any extension or additional patents.
The prospective amendment of the amortization plan of the monalizumab intangible asset, which is modified according to the estimate ending date of
the Phase II clinical trial is described in Note 6.

3) Management of financial risks and fair value

The principal financial instruments held by the Company are cash, cash equivalents and marketable securities. The purpose of holding these instruments is

to finance the ongoing business activities of the Company. It is not the Company’s policy to invest in financial instruments for speculative purposes. The Company
does not utilize derivatives.

The principal risks to which the Company is exposed are liquidity risk, foreign currency exchange risk, interest rate risk and credit risk.

Liquidity risk

The Company’s cash management is performed by the Finance department, in charge of monitoring the day-to-day financing and the short-term forecast and

enabling the Company to face its financial commitments by maintaining an amount of available cash consistent with the maturities of its liabilities. As of
December 31, 2019, cash, cash equivalents and short-term investments were €218,865 thousand, which represents more than a year of cash consumption.

F-33

 
 
 
 
 
 
 
The main characteristics of the financial instruments owned by the Company (including liquidity) are presented in Note 4.

Foreign currency exchange risk

The Company is exposed to foreign exchange risk inherent in certain subcontracting activities relating to its operations in the United States, which have

been invoiced in U.S. dollars. The Company does not currently have recurring revenues in euros, dollars or in any other currency. As the Company further
increases its business, particularly in the United States, it is expected to face greater exposure to exchange rate risk.

The revenue denominated in U.S. dollars has represented approximately 100% of revenue in the years ended December 31, 2017, 2018 and 2019,
respectively. Payments in U.S. dollars represented approximately 15.1%, 31.9%, 64.1% of the payments in the years ended December 31, 2017, 2018 and 2019,
respectively. In order to cover this risk, the Company kept in U.S. dollars a part of the consideration received from AstraZeneca in June 2015 and January 2019.
We entirely kept the U.S dollars portion of the proceeds received from our Global Offering in October 2019.

The Company’s foreign exchange policy does not include the use of hedging instruments.

Interest rate risk

The Company has very low exposure to interest rate risk. Such exposure primarily involves 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 Company has no credit facilities. The repayment
flows of the advances from Banque Publique d’Investissement (“BPI France”) and the borrowings subscribed in 2017 are not subject to interest rate risk.

Credit risk

The credit risk related to the Company’s cash equivalents, short-term investments and non-current financial assets is not significant in light of the quality of

the issuers. The Company deemed that none of the instruments in its portfolio are exposed to credit risk.

Fair value

The fair value of financial instruments traded on an active market is based on the market rate as of December 31, 2019. The market prices used for the

financial assets owned by the Company are the bid prices in effect on the market as of the valuation date.

Cash and cash equivalents are mainly composed of current bank accounts, interest-bearing accounts and fixed-term accounts.

In the year ended December 31, 2017, shares in mutual funds are defined by the Company as assets available for sale measured at fair value through other
comprehensive income. From January 1, 2018 and the first application of IFRS 9, they are accounted for as financial assets at fair value through profit and loss.
The Company only invests into funds with a very low level of risk. As of December 31, 2019, the Company owns shares of four mutual funds. The risk profiles of
these funds are rated 1 to 7 by the financial institution who manages and commercializes these funds (1 being the lowest risk profile). When the maturity of shares
in mutual funds is longer than one year, they are classified as non-current financial instruments.

Other non-current financial assets generally include a guarantee of capital at the maturity date (which is always longer than one year). These instruments are

defined by the Company as financial assets at fair value through profit or loss and classified as non-current due to their maturity.

As of December 31, 2017, 2018 and 2019 the amount of cash, cash equivalents and financials assets denominated in US dollars amounted respectively to

€59,348 thousand, €74,442 thousand and €97,688 thousand

The variation of short-term investments and non-current financial assets for the periods presented, are the following:

_________________
“Other receivables” as of December 31, 2018, mainly related to AstraZeneca as a result of the exercise of the monalizumab exclusive license option
($100,000 thousand or €87,655 thousand) and option granted on IPH5201 ($24,000 thousand or €20,961 thousand). These amounts were paid in the first
quarter of 2019, see Note 1.1.a and Note 1.1.c for agreements description.

In accordance with the principles described in Note 2.u, the research tax credit (Crédit d’Impôt Recherche or “CIR”) is recognized as other operating income
in the year to which the eligible research expenditure relates. The Company obtained the repayment of the CIR for the tax year 2017 in the amount of
€11,022 thousand in 2018 and the repayment of the CIR for the tax year 2018 in the amount of €13,503 thousand in July 2019. The CIR for the tax year
2019 amounted to 16,737 thousand. Following the fact that the Company no longer meets the eligibility criteria for the SME status as of December 31, 2019,
the CIR for the tax year 2019 will in principle be offset against the French corporate income tax due by the company with respect to the three following
years, or refunded if necessary upon expiry of such a period (see note 2.u).

The rebate refers to a definitive rebate of $7,580 thousand as of December 31, 2019 ($15,000 thousand as of December 31, 2018) granted by AstraZeneca in
connection with the acquisition of Lumoxiti rights and that will be paid in 2020. This decrease of $ 7,420 thousand (€6,455 thousand) is based on the final
cost figures for the 2019 financial year for Lumoxiti and invoiced by AstraZeneca. The carrying amount of the intangible asset has been adjusted
accordingly (see note 6).

Trade receivables and others have payment terms of less than one year. No valuation allowance was recognized on trade receivables and others as the credit

risk of each of debtors was considered as not significant.

This amount is an upfront payment for acquisition of avdoralimab rights under the in-licensing agreement signed in 2017 with Novo Nordisk A/S. The
classification of this amount has been amended compared to the 2017 consolidated financial statements since it is in progress and thus not amortized.

This amount mainly includes (i) an upfront payment of €43,501 thousand, less an estimate rebate of €13,050 thousand relating to the rights acquired from
AstraZeneca in 2018 under the Lumoxiti in-licensing agreement and (ii) a €13,050 thousand additional consideration to be paid to Novo Nordisk A/S
following the exercise of the option by AstraZeneca for the monalizumab rights.

This amount includes (i) an additional consideration of €7,000 thousand paid to Orega Biotech in June 2019 in relation to the anti-CD39 program as
consideration following the collaboration and option agreement signed in October 22, 2018 with AstraZeneca regarding IPH5201 (see Note 1.c), (ii) the
decrease of the rebate granted by AstraZeneca in connection with the acquisition of Lumoxiti rights for an amount of €6,455 thousand (see Note 5 and (2)
above ), and (iii) an additional consideration of €13,565 thousand paid to AstraZeneca in January 2020 following the submission to the European Medicines
Agency (EMA) of the Marketing Authorization Application (MAA) relating to the commercialization of Lumoxiti in Europe (see Note 1.2).

(4)

This amount includes the amortization of rights related to monalizumab (€4,792 thousand), IPH5201 (€6,831 thousand) and Lumoxiti (€2,730 thousand).

Monalizumab rights under the 2014 monalizumab (NKG2A) Novo Nordisk agreement

At the agreement inception, acquired rights were recorded as intangible asset for an amount of €7,000 thousand. The Company recorded an additional

consideration of €6,325 thousand in 2015 and a final consideration of $15,000 thousand (€13,050 thousand) due in 2018 (see Note 1.1.a).

Since their acquisition by the Company, monalizumab rights are amortized on a straight-line basis over the anticipated residual duration of the Phase II
trials. The Company has reassessed the anticipated residual duration of the Phase II trials as of December 31, 2019 and estimated that it would be fully amortized
by the end of 2021, compared to end of 2019 as estimated as of December 31, 2018, as a result of the completion of some trials and initiation of new cohorts. The
impact of this revision for the fiscal year ended December 31, 2019 amounts to €4,452 thousand.

The net book values of the monalizumab rights were €7,941 thousand and €12,733 thousand as of December 31, 2019 and December 31, 2018, respectively.

IPH5201 (Anti-CD39) rights acquired from Orega Biotech

On January 4, 2016, the Company and Orega Biotech entered into an exclusive licensing agreement by which Orega Biotech granted the Company full

worldwide rights to its program of first-in-class anti-CD39 checkpoint inhibitors. The undisclosed upfront payment paid by the Company to Orega Biotech has
been recognized as an intangible asset in the consolidated financial statements for the year ended December 31, 2016. Criteria relating to the first development
milestone were reached in December 2016. Consequently, the amount of this milestone was recognized as an intangible asset in addition to the initial payment, for
a total of €1.8 million as of December 31, 2018. In June of 2019, the Company also paid Orega Biotech €7.0 million in relation to the anti-CD39 program as
consideration following the collaboration and option agreement signed on October 22, 2018 with AstraZeneca regarding IPH5201.

This asset is amortized on a straight-line basis since November 1, 2018 (corresponding to the effective beginning date of the collaboration) until the date the

Company expects to fulfill its commitment (end of fiscal year 2020).

The Company may also be obligated to pay Orega Biotech up to €51,500 thousand upon the achievement of development and regulatory milestones. In

addition, the Company will be obligated to pay mid-single digit to low-teen percentage payments, depending on determinations relating to Orega Biotech’s
intellectual property rights for certain patents, on sublicensing revenues the Company receives pursuant to its agreement with AstraZeneca relating to IPH5201.

Avdoralimab (IPH5401) (anti-C5aR) rights acquired from Novo Nordisk A/S

At the agreement inception, an upfront payment of €40 million for acquired rights were recorded as intangible asset. As avdoralimab is still in clinical trial,
the acquired rights are classified as intangible asset in progress. They were subject to annual impairment test. No impairment were recorded since inception. These
acquired rights will be amortized when the Company obtains economic benefits.

According to the agreement, the Company will pay additional payments according to the reach of specific steps. As of December 31, 2019, according to the

uncertainty of these potential payments, no liability was recognized.

Development costs incurred by the Company are recognized as research and development expenses.

The main assumptions used for the impairment test are the following:

•
•
•

Cash flows are set on the basis of the development and commercialization plans and budgets approved by Management;
A discount rate of 12%;
A risk of development is taken into consideration by applying probabilities of success of reaching future phases of development to cash flows related
to each development phases Those average probabilities of success of R&D projects are based on an article published in Nature Biotechnology
journal;

F-39

 
 
 
 
 
 
 
 
 
 
•

For the commercialization phase, selling price and sales volume are estimated on the basis of the potential market and the observed performances of
comparable drugs currently on the market. Decrease in sales volume applied to the forecasted revenue once the related rights fall off-patent.

In case of failure of the clinical trials in progress, the Company may have to depreciate the intangible asset corresponding to the avdoralimab rights.

The Company did not identify any reasonable potential variance in the key assumptions that may generate an impairment.

Sensitivity testing regarding these following assumptions and other assumptions such as: discount rate (+/- 3%), selling price (+/- 10%) and decrease in sales
volume once the related rights fall off-patent (+/- 5%) were performed. These tests did not reveal any impairment.

Avdoralimab does not generate economic benefits yet for the Company. In accordance with IAS 38, it will be amortized when it generates economic

benefits, which can result from:

•
•

The commercialization the drug candidate; or,
An out-licensed agreement.

If the Company commercialize the drug product on its own, it will have to determine the amortization period of the related capitalized rights. It will have to

estimate their useful life, considering the date when they fall off patent. Those capitalized rights will be amortized on a straight line basis during the estimated
useful life.

If the Company entered in an out-licensed agreement, the Company will have to perform an analysis to determine if the control of the rights are transferred

to a third-party, and thus will have to derecognize the capitalized rights. If the Company conclude that it keeps the control of the rights, it will determine their
useful life and will amortize them on a straight line basis during this useful life.

Lumoxiti rights acquired from AstraZeneca under the 2018 AstraZeneca multi-term agreement

The license by which the Company acquired Lumoxiti rights is amortized on a straight-line basis through July 31, 2031, which corresponds to the expiration

of the current composition of matter patent, not including any additional patent extensions or patents. The net book value of the Lumoxiti rights was
€47,276 thousand and €29,987 thousand as of December 31, 2019 and December 31, 2018, respectively. This increase in the net book value resulting from (i) the
decrease of the rebate granted by AstraZeneca in connection with the acquisition of Lumoxiti rights for an amount of €6,455 thousand (see Note 6), and (ii) an
additional consideration of €13,565 thousand paid to AstraZeneca in January 2020 following the submission to the European Medicines Agency (EMA) of the
Marketing Authorization Application (MAA) relating to the commercialization of Lumoxiti in Europe. These additional considerations are partly offset by the
period amortization (€2,730 thousand).

The Company applied IAS 36- Impairment of assets and assessed whether there was any indication that an asset may be impaired. The Company estimated

the recoverable amount of Lumoxiti intangible assets using a discounting cash flow model which confirmed that these assets were not impaired. The following
assumptions were used to determine the recoverable amount, based on the cash flows determined from the commercialization plan and the budget approved by
Management:

•
•
•

A discount rate of 12%
Assumptions related to selling price increase and sales volume based on the potential market and comparable products; and
Decrease in sales volume applied to the forecasted revenue once the related rights fall off-patent.

Sensitivity testing regarding the following assumptions and other assumptions such as: discount rate (+/- 3%), selling price (+/- 10%) and decrease in sales volume
once the related rights fall off-patent (+/- 5%) were performed. These tests did not reveal any impairment.

In 2013, the Company was granted an interest-free loan for innovation (“PTZI”) by BPI France relating to the program lacutamab IPH4102 for an amount of

€1,500 thousand.

Finance lease obligations relate primarily to real estate property in relation to the acquisition in 2008 of the Company’s headquarters and main laboratories.

They are presented in the above table net of the cash collateral paid to Sogebail, the lessor. In the context of this operation, the Company paid a guarantee in the
form of a down-payment. This down-payment amounts to €74 thousand as of December 31, 92019 (€234 thousand as of December 31, 2018).

On July 3, 2017, the Company borrowed from the Bank “Société Générale” in order to finance the construction of its future headquarters. This loan

amounting to a maximum of €15,200 thousand will be raised during the period of the construction in order to pay the supplier payments as they become due. As of
December 31, 2017 and 2018, the loan was raised at an amount of €1,300 thousand.

The loan release period was limited to August 30, 2019. On August 30, 2019, the Company drew down the remaining portion of the €15,200 thousand loan

granted, for an amount of €13,900 thousand. The reimbursement of the capital has begun in August 30, 2019 and will proceed until August 30, 2031 (12 years). As
of December 31, 2019, the remaining capital of the loan amounted to €14,826 thousand. The Company authorized collateral over financial “Société Générale”
instruments amounting to €15,200 thousand. The security interest on the pledge financial instruments will be released in accordance with the following schedule:
€4,200 thousand in July 2024, €5,000 thousand in July 2027 and €6,000 thousand in July 2031.

This loan bears a fixed interest rate of 2.01%. It is subject to a covenant based on the assumption that the total cash, cash equivalents and current and non-

current financial assets are at least equal to principal as of financial year end.

French law requires payment of a lump sum retirement indemnity to employees based on years of service and annual compensation at retirement. Benefits

do not vest prior to retirement. The Company pays for this defined benefit plan. It is calculated as the present value of estimated future benefits to be paid,
applying the projected unit credit method whereby each period of service is seen as giving rise to an additional unit of benefit entitlement, each unit being
measured separately to build up the final.

On March 24, 2016, the Company entered into an internal labor agreement with the employees representatives whereby the Company is committed to
paying a seniority award after 15 years and 20 years of employment. This award is paid on the anniversary date. A similar award existed for employees having a
seniority of 10 years but was not booked due to its insignificant amount. As such, in 2016 the Company recorded a provision for seniority awards and a
corresponding charge included in “Personnel costs other than share-based payments” (see Note 14) other than payments in shares. These awards meet the
definition of other long-term benefits under IAS 19. This provision is determined by an external actuary firm based on the assumptions disclosed hereafter and
amounts to €479 thousand as of December 31, 2019 (€415 thousand as of December 31, 2018).

An increase/decrease of +/- 50 basis point of the discount rate would result in a decrease/increase of the total benefit obligation of €286 thousand.

In France, pension funds are generally financed by employer and employee contributions and are accounted for as defined contribution plans with the

employer contributions recognized as expensed as incurred. They amounted to €982 thousand, €1,277 thousand and €1,375 thousand in the years ended
December 31, 2017, 2018 and 2019, respectively.

11) Share capital and share base payments

a) Share capital

The  Company  manages  its  capital  to  ensure  that  the  Company  will  be  able  to  continue  as  a  going  concern  while  maximizing  the  return  to  shareholders

through the optimization of the debt and equity balance.

We have never declared or paid any 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.

As of December 31, 2019, the Company’s share capital amounted to €3,941,281.05 divided into (i) 78,811,114 ordinary shares, each with a nominal value of
€0.05, (ii) 6,926 “2016” free preferred shares, each with a nominal value of €0.05 and (iii) 7,581 “2017” free preferred shares, each with a nominal value of €0.05,
respectively fully paid up.

Share capital does not include BSAs, BSAAR,AGAs and AGAPs that have been granted to certain investors or natural persons, both employees and non-

employees of the Company, but not yet exercised.

In October 21, 2019 and December 30, 2019, the retention period for the “2016 free preferred shares” has ended. The number of ordinary shares to which
the conversion of one preferred share entitle has been determined according to the fulfilment of the performance criteria. Holders of “2016” preferred shares” are
entitled to vote at our shareholders’ meetings, to dividends and to preferential subscription rights, on the basis of the number of ordinary shares to which they are
entitled if they convert their preferred shares.

The Group issued preferred shares “2017 free preferred shares” which will become convertible into ordinary shares following a vesting period of one year
and a retention period of two years if the performance criteria and presence are met at the end of the retention period. The number of ordinary shares to which the
conversion of one preferred share will entitle will be determined according to the fulfilment of the performance criteria. During the retention period, holders of the
2017 preferred shares are entitled to vote the general shareholders’ meetings, to dividends and to preferential subscription rights, as if they held the same number
of ordinary shares as their number of vested 2017 free preferred shares. The 2017 preferred shares are not transferrable during the retention period except under
certain circumstances. After the end of the retention period, holders of all of preferred shares that have not yet converted them into our ordinary shares, are entitled
to vote at our shareholders’ meetings, to dividends and to preferential subscription rights, on the basis of the number of ordinary shares to which they are entitled
if they convert their preferred shares.

In October 21, 2019 and December 30, 2019, the retention period for the “2016 free preferred shares” has ended. The number of ordinary shares to which the
conversion of one preferred share entitle has been determined according to the fulfilment of the performance criteria. Holders of “2016” preferred shares” are
entitled to vote at our shareholders’ meetings, to dividends and to preferential subscription rights, on the basis of the number of ordinary shares to which they are
entitled if they convert their preferred shares.

BSAAR

BSAAR are securities whose subscription price and exercise price are fixed at their fair value as determined by an expert. The BSAAR subscription
therefore represents an investment on the part of the beneficiary. At the end of the exercise period, if they have not been exercised, the BSAAR becomes void. The
Company benefits from a clause called «forcing» making it possible to encourage holders to exercise their redeemable equity warrants when the market price
exceeds the exercise price and reaches a threshold defined in the BSAAR issuance agreement. The Company may, then, subject to a time period for notifying
holders that will permit them to exercise the BSAAR, decide to reimburse the warrants not exercised at a unit price equal to the BSAAR acquisition price paid by
its holder.

Details of BSAAR

BSAAR. The methodology used to estimate the fair value of the BSAAR is similar to the one used to estimate the fair value of the BSA, except for the

following:

Expected Term. Unlike the BSA, the Company does not have sufficient historical experience for the BSAAR. Consequently, the expected term used for the

valuation of the fair value is the legal maturity of the instrument (10 years).

No share-based payment compensation expense was recognized relating to the BSAAR since the amount paid by the beneficiaries is equal to the fair value.

The fair value of financial assets classified as fair value through profit and loss corresponds to the market value of the assets, which are primarily
determined using level 2 measurements.
The fair value of financial assets classified as fair value through comprehensive income corresponds to the market value of the assets, which are primarily
determined using level 1 measurements.
The book amount of financial assets and liabilities measured at amortized cost was deemed to be a reasonable estimation of fair value.

(2)

(3)

In accordance with the amendments to IFRS 7, financial instruments are presented in three categories based on a hierarchy of methods used to determine

fair value:

Level 1: fair value determined based on quoted prices in active markets for assets or liabilities;

Level 2: fair value determined on the observable database for the asset or liability concerned either directly or indirectly;

Level 3: fair value determined on the basis of evaluation techniques based in whole or in part on unobservable data.

The Company identified the following promises under the monalizumab AstraZeneca agreements and amendments: (1) a non-exclusive license related to
monalizumab  restricted  to  two  applications,  with  an  option  for  an  exclusive  license  related  to  monalizumab  including  all  applications,  (2)  the  performance  of
certain initial studies related to phases I/II trials, and participation in certain studies of phases I/II trials and phase III clinical trials through a co-financing.

The Company considered the license has a standalone functionality and is capable of being distinct. However the Company determined that the license is
not  distinct  from  the  performance  of  initial  studies  and  participation  to  phase  III  clinical  trials  because  they  increased  the  utility  of  the  licensed  IP.  Thus,  the
licensed IP, the performance of initial studies and participation to phase III clinical trials are combined into a single performance obligation.

This performance obligation was considered as satisfied over time as AstraZeneca controls the licensed IP which is being enhanced during the agreement.
The revenue is recognized over time, based on the input method (costs incurred). As a result, the Company recognizes the price of the transaction as a revenue on
the basis of the progress of studies that the Company has undertaken to carry out under the agreement. Progression is assessed following to actual costs incurred
relative to the total budgeted costs to fulfill the obligation.

The transaction price was initially estimated to the initial payment of $250,000 thousand, less the amounts that the Company expected to pay to AstraZeneca
for co-financing Phase I/II clinical studies. The additional payment of $100,000 thousand triggered by AstraZeneca’s exercise of the exclusivity option was treated
as a change in the price estimate of the transaction. In addition, the amendment of the contract, which modified the scope and budget of the studies to be carried
out by the Company as well as the arrangements for sharing the cost of the other studies, led to a revision of the degree of progress and the price of the transaction.
Thus,  the  exercise  of  the  option  and  the  amendment  of  the  contract  resulted  in  the  recognition  of  a  favorable  cumulative  adjustment  of  €38,321  thousand  in
revenue for the year ended December 31, 2019.

The subsequent milestones and potential royalty payments are excluded from the transaction price due to the uncertainties of clinical trials results.

The Company used the most likely amount to determine variable consideration. Variable consideration for cost-sharing payments related to certain studies

of phases I/II trials and phase III clinical trials when applicable are included in the transaction price.

The Company and AstraZeneca make quarterly cost-sharing payments to one another in amounts necessary to ensure that each party bears its contractual
share  of  the  overall  shared  development  costs  incurred.  Costs  incurred  by  the  Company  related  to  agreed-upon  services  under  the  agreement  are  recorded  as
research and development expenses in its consolidated statements of financial income (loss). The Company accounts for cost sharing payments from AstraZeneca
as increase in revenue in its consolidated statements of income (loss), while cost sharing payments to AstraZeneca are recorded as payments to customer which
reduce the transaction price recorded as revenue from the collaboration agreement. As described in Note 2. d, the expected payments to AstraZeneca are classified
as collaboration liability in the consolidated statement of financial position. Quarterly invoices received from AstraZeneca reduce the collaboration liability and
have no impact on the consolidated statement of income.

The Company determined that IPH5201 AstraZeneca collaboration and option agreement is an enforceable contract under IFRS 15 as the upfront payment
is non-refundable and thus AstraZeneca will incur significant loss if it doesn’t exercise its licensed option. The Company considered that the exercise price of the
option granted to AstraZeneca for an exclusive license is a variable consideration.

The Company identified the following promises under the IPH5201 AstraZeneca collaboration and option agreement: (1) an option for an exclusive license

related to IPH5201 and (2) the performance of research and development services in conformity with the defined development plan for preclinical studies. The
Company determined that the option is not distinct from the performance of research and development services because they increased the utility of the licensed
IP. Thus, the option and the performance of research and development services are combined into a single performance obligation.

The transaction price was initially estimated to the initial upfront payment of $50,000 thousand (received in October 2018 for $26,000 thousand and in

January 2019 for $24,000 thousand) and estimated quarterly payment received in relation to costs incurred by the Company for preclinical studies. Development
and commercial milestones and potential royalties payments were excluded from the transaction price due to uncertainties.

The performance obligation was considered as satisfied over time as the IP in development has no alternate use for the Company as it is an exclusive license

and that the Company has an enforceable right to payment for completed research and development services.

The Company applied the input method and recognized the price of the transaction as a revenue percentage of completion of the costs of the preclinical

studies.

c) Revenue related to collaboration and option agreement related to four to-be-agreed upon molecules (preclinical molecules)

The Company determined that the option to acquire an exclusive license provides a material right to AstraZeneca that it would not receive without entering
into that contract. The Company will recognize revenue when those future goods or services are transferred or when the option expires. Thus, the upfront payment
is recorded as a deferred revenue for an amount of €17,400 thousand as of December 31, 2019.

d) Revenue recognition related to avdoralimab AstraZeneca agreement

The Company recognized revenue as research and development expenses are incurred (see Note 1.1.e for agreement description).

15) Net income / (loss) from distribution agreements

During the transition period, which is expected to terminate by the end of 2020, Lumoxiti products are commercialized in the United States by AstraZeneca
who is the owner of the regulatory approval. The Company concluded that it did not meet the criteria for being principal under IFRS 15. Consequently, the net loss
resulting from all Lumoxiti marketing operations are disclosed in the item line “Net income / (loss) from distribution agreements”

The Company recognized a €1,109 thousand net loss and a €8,219 thousand net loss for the fiscal years ended December 31, 2018 and 2019 respectively,

corresponding to production and marketing costs, net of sales proceeds, as invoiced by AstraZeneca in relation to Lumoxiti distribution agreement for the period.

For the financial years ended December 31, 2018 and 2019, the foreign exchange gains and losses mainly result from the variance of the exchange rate

between the Euro and the U.S. dollar on U.S. dollars denominated cash and cash equivalent and financial assets accounts.

Unrealized losses on financial assets relate to unquoted instruments, the fair value of which is determined using level 2 measurements.

17) Income Tax

Due to the Company’s early stage of development, it is not probable that future taxable profit will be available against which the unused tax losses can be

utilized. As a consequence, deferred tax assets are recognized up to deferred tax liabilities.

Temporary differences mainly result from leases, provision for defined benefit obligation and tax losses carryforwards.

As of December 31, 2019, the accumulated tax losses carryforwards of Innate Pharma SA were €231,167 thousand with no expiration date (€218,670 and

€219,563 thousand as of December 31, 2017 and 2018). As of December 31, 2019, the accumulated tax losses carryforwards of Innate Pharma Inc. was
€5,098 thousand, or $5,727 thousand, (€446 thousand, or $535 thousand and €493 thousand, or $564 thousand as of December 31, 2017 and 2018, respectively),
with a 20-year period expiration.

For the financial year 2018, the Company opted for the carry back mechanism which gave rise to a €333 thousand tax credit.

course of its activities. Each pre-litigation, known litigation or procedure in ordinary course the Company is involved in was analyzed at the closing date after
consultation of advisors. There is no acknowledged litigation as of December 31, 2019.

In November 2019, Impletio Wirkstoffabfüllung GmbH (formerly known as Rentschler Fill Solutions GmbH), the subcontractor in charge of the fill-and-
finish manufacturing operations of lacutamab unilaterally decided to withdraw the certificates of conformance of all clinical batches produced at their facilities,
including the lacutamab batch used for the TELLOMAK Phase II clinical trial assessing lacutamab in multiple indications. Impletio Wirkstoffabfüllung GmbH
decided to withdraw the certificates of conformance even though the compliance of its manufacturing site with Good Manufacturing Practices has been confirmed
by two on-site inspections performed by a local regulator before and after we began to work with them.

Impletio Wirkstoffabfüllung GmbH has filed for bankruptcy, bankruptcy proceedings are currently underway in Austria.

plan conditions actions for employees when they join the Company at the end of the plan.

commercialization of Lumoxiti in Europe. According to the agreement related to Lumoxiti with AstraZeneca, AstraZeneca is entitled to a $15,000 thousand
milestone that was paid by the Company in January 2020. On January 2, 2020, the Company announced that the EMA has accepted the MAA submission for

The  share  capital  is  €  3,945,638.55  (three  million  nine  hundred  forty-five  thousand  six  hundred  thirty-eight  euros  and  fifty-five  cents).  It  is  divided  into
78,898,264 (seventy-eight million eight hundred ninety-eight thousand two hundred sixty-four) ordinary shares of zero point zero five (0.05) euro each, 6,926 (six

thousand five hundred eighty-one) preference shares of zero point zero five (0.05) euro each (herein referred to as “2017 Preference Shares”), fully subscribed
and fully paid up in cash.

ARTICLE 7 – Modifications of the Share Capital

I.       The share capital may be increased by either the issue of new shares or an increase of the nominal value of existing shares.

New  shares  are  paid  up  either  in  cash,  by  a  contribution  in  kind,  by  set-off  against  due  and  payable  receivables,  by  incorporation  of  profit,  reserves  or  issue
premiums into the share capital, as a result of a merger or demerger, or further to the exercise of a right attached to securities entitling their holder to capital,
including, as the case may be, the payment of the corresponding amounts.

New shares are issued at either their nominal amount or at such amount increased by an issue premium.

A share capital increase can only be decided by an Extraordinary Meeting of Shareholders, following a report by the Executive Board containing the information
required by law.

An Extraordinary Meeting of Shareholders may, however, delegate such competence to the Executive Board pursuant to the conditions provided by law. Within
the limit of the powers so granted by an Extraordinary Meeting of Shareholders, the Executive Board shall have the powers required to increase the share capital
in  one  or  several  steps,  to  determine  the  terms  and  conditions  thereof,  to  officially  acknowledge  the  completion  thereof  and  to  make  the  corresponding
amendments to the articles of association.

If a share capital increase is decided by a Meeting of Shareholders, it may delegate all the powers required for the completion of the operation to the Executive
Board.

If the Executive Board is acting by virtue of a delegation of power or competence, it shall prepare a supplementary report to the Ordinary Meeting of Shareholders
held following the meeting of the Executive Board at which such action is taken.

If the share capital is increased by the incorporation of profits, reserves or issue premiums, the Extraordinary Meeting of Shareholders shall deliberate pursuant to
the  conditions  of  quorum  and  majority  required  for  Ordinary  Meeting  of  Shareholders.  In  such  case,  the  Meeting  of  Shareholders  may  decide  that  rights
constituting  fractional  shares  shall  be  neither  negotiable  nor  transferable  and  that  the  corresponding  securities  should  be  sold.  The  proceeds  of  sale  shall  be
allocated to the holders in proportion to their rights.

An increase in share capital by increasing the nominal amount of shares may only be decided by a unanimous decision of the shareholders, unless it is the result of
an incorporation of profits, reserves or issue premiums into the share capital.

TRANSLATION FOR INFORMATION PURPOSES

Shareholders have a preferential right of subscription, in proportion to their shareholdings, to shares issued by way of cash contribution in order to increase the
share capital. Shares acquired pursuant to the exercise of this right shall be of the same category as that of the share from which the aforesaid right arises. This also
applies to shares resulting from the acquisition of securities other than shares.

Shareholders  may  dispose  of  all  or  part  of  their  subscription  rights  during  the  subscription  period.  Such  rights  are  negotiable  if  they  are  detached  from  shares
which are themselves negotiable. If this is not the case, then such subscription rights may be disposed of on the same terms as the shares themselves.

Shareholders may waive their preferential right on an individual basis.

The Extraordinary Meeting of Shareholders which decides to increase the share capital may cancel the preferential right to subscription pursuant to the conditions
and within the limits set by law, and shall make such decision following the issuance of reports of the Executive Board and the Statutory Auditors, in accordance
with the conditions determined by the law and regulations in force.

Shares which have not been subscribed for on an irreducible basis may be allocated to shareholders who may have subscribed on a reducible basis for a greater
number of shares than that to which they could have subscribed on a preferential basis, in proportion to their subscription rights, and in any event, within the limit
of their request, if the Extraordinary Meeting of Shareholders, or, in the case of delegation, the Executive Board, expressly so decides.

If  the  subscriptions  have  not,  in  any  respect  whatsoever,  covered  the  entire  share  capital  increase,  the  Executive  Board  may  exercise  any  one  or  more  of  the
options provided below, in the order it sees fit:

limit the share capital increase to the amount of the subscriptions on the dual condition that such subscriptions cover at least three quarters of the amount of
the originally determined increase, and that such  option  has  not  been  expressly  prohibited  by  the  Extraordinary  Meeting  of  Shareholders  at the time of
issue;

(ii)

allocate the remaining shares unless the Extraordinary Meeting of Shareholders has decided otherwise; and

(iii)

opening the subscription to the public if this has been expressly authorised by the Extraordinary Meeting of Shareholders.

If  the  subscriptions  have  not  covered  the  entire  share  capital  increase,  or  three  quarters  of  this  increase  in  the  case  of  (i)  above,  after  such  options  have  been
exercised, the share capital increase shall not be carried out.

However, the Executive Board may in any case automatically limit the share capital increase to the amount covered by subscriptions, if unsubscribed shares
represent less than 3% of the share capital increase.

In the case of a share capital increase with or without a preferential right of subscription, the Extraordinary Meeting of Shareholders may provide that the number
of shares may be increased within thirty days of the closure of subscriptions by up to 15% of, and at the same price as for, the original issue.

If the share capital increase produces fractional shares, shareholders with insufficient subscription or allocation rights shall be required personally to acquire or
dispose of the subscription rights necessary to obtain delivery of a whole number of new shares.

II.       An Extraordinary Meeting of Shareholders (or, in the case of delegation, the Executive Board) may also (subject to the rights of creditors if relevant)
authorise or decide upon a reduction of share capital for any reason and by any procedure whatsoever. A reduction in share capital may not, in any event, derogate
from the principle of equality between shareholders.

TRANSLATION FOR INFORMATION PURPOSES

The reduction of share capital to an amount below the legal minimum can only be decided subject to the condition precedent of a share capital increase to at least
the  statutory  minimum,  unless  the  Company  is  transformed  into  a  company  having  a  different  corporate  form.  In  the  event  that  the  foregoing  principle  is  not
complied with, any interested party may ask the courts to dissolve the Company, provided however that the dissolution of the Company cannot be ordered if, as of
the date on which the court rules on the merits, the situation has been rectified.

Subject to the legal and regulatory provisions in force, the Company may not either subscribe to or purchase its own shares. However, if an Extraordinary Meeting
of Shareholders has decided on a reduction of share capital for reasons other than due to losses, it can authorise the Executive Board to purchase a fixed number of
shares in order to cancel them.

ARTICLE 8 – Paying Up Shares

At least one quarter of the nominal value of shares subscribed for cash must be paid up on subscription together with the full amount of the issue premium, if
relevant.

The  remainder  must  be  paid  up  in  one  or  more  instalments,  upon  calls  made  by  the  Executive  Board,  within  five  years  of  the  day  on  which  the  share  capital
increase was completed.

Subscribers will be informed of calls for funds by registered letter with confirmation of receipt sent at least fifteen days prior to the date set for each payment.

If a shareholder does not pay the amounts due with respect to the shares for which he has subscribed, on the dates determined by the Executive Board, interest will
automatically accrue on such amounts in favour of the Company at the statutory rate defined in Article L. 313-2 of the Monetary and Financial Code, as of the
expiry of the month following the date on which they fall due and without the need for a court petition or formal notice. Moreover, when due payments in respect
of shares have not been made within thirty days of formal notice sent to the defaulting shareholder, such shares will no longer entitle the holder to admission to
shareholders’  meeting  and  the  right  to  vote  in  shareholders’  meetings,  and  shall  be  deducted  for  the  calculation  of  the  quorum.  The  right  to  dividends  and  the
preferential right of subscription to share capital increases attached to these shares shall be suspended. These rights shall be regained on payment of the principal
and interest due in respect of the amounts due. A shareholder can then request the payment of dividends that are not time-barred and exercise his preferential right
of subscription if the exercise period for such right has not expired.

The share capital must be fully paid up prior to any issue of additional shares to be paid up in cash.

ARTICLE 9 – Form of Shares – Administration of the Share Accounts

Ordinary shares are either in registered form or, if allowed by law, in bearer form, at the shareholder’s discretion. Fully paid-up 2016 Preference Shares are in
registered form. Fully paid-up 2017 Preference Shares are in registered form.

Ordinary shares, 2016 Preference Shares and 2017 Preference Shares are registered in individual accounts opened by the Company or any authorised intermediary,
in the name of each shareholder and kept according to the conditions and procedures provided by legal and regulatory provisions.

The Company is authorised to rely on statutory provisions, in particular Article L. 228-2 of the Commercial Code, with respect to the identification of the holders
of bearer shares and for such purpose it may at any time request the central depositary who administers the share account, to provide the information referred to in
Article L. 228-2 of the Commercial Code, in exchange for payment. The Company is therefore, in particular, entitled at any time to request the name and year of
birth, or concerning a legal person, the corporate name and year of incorporation, the nationality and the post address and, if applicable, email address of holders
of securities which give the right to vote in Meeting of Shareholders, either immediately or in the future, as well as the number of shares held by each of them and,
as the case may be, any restrictions which may apply to the shares.

ARTICLE 10 - Transfer of Shares

Registered shares may be transferred by transfer from one account to another.

Ordinary shares paid up in cash are freely transferable as from the completion of the share capital increase. Ordinary shares received in exchange for contribution
in kind are freely transferable as from the completion of the share capital increase, i.e. on the date of the Meeting of Shareholders or meeting of the Executive
Board, acting under delegation, which approved the contribution, in the case of an in-kind contribution during the life of the company.

Title to ordinary shares is transferred by registration in the buyer’s account, on the date and in accordance with the conditions provided by applicable law and, as
the case may be, regulations.

Ordinary shares are freely transferable subject to legislative provisions. 2016 Preference Shares and 2017 Preference Shares are transferable under the conditions
set forth in Article 12 of these by-laws.

ARTICLE 11 – Crossing of Thresholds

Any natural person or legal entity referred to under Articles L. 233-7, L. 233-9 and L. 223-10 of the Commercial Code who gains possession, directly or indirectly,
alone or in concert, of a number of shares which represent a portion of the share capital or voting rights of the Company equal to or greater than 1% or a multiple
of such percentage, must inform the Company of the total number of shares, voting rights and securities granting an interest in capital or voting rights which it
owns immediately or would own in the future, by registered mail with confirmation of receipt sent to the registered office of the Company within five trading days
starting from the date that the aforesaid threshold(s) were crossed.

The obligation of information provided above also applies in the same conditions when the aforesaid thresholds are crossed downwards.

Shares  or  voting  rights  in  excess  of  the  portion  which  should  have  been  declared  but  which  have  not  been  declared  pursuant  to  the  aforesaid  conditions,  are
stripped  of  their  rights  to  vote  at  shareholders’  meetings  for  any  meeting  held  within  two  years  following  the  date  of  the  regularisation  of  the  declaration  in
accordance  with Article  L.  233-14  of  the  Commercial  Code,  if  failure  to  make  the  declaration  has  been  observed  and  if  one  or  more  shareholders  holding  an
interest of at least 5% of the share capital of the Company make such request, recorded in the minutes of the Meeting of Shareholders.

The foregoing obligations to declare apply in addition to the threshold crossing declarations provided by legal or regulatory provisions in force.

ARTICLE 12 - Rights and Obligations attached to Shares

The share capital of the Company is divided between ordinary shares, 2016 Preference Shares and 2017 Preference Shares.

I. Rights attached to ordinary shares, 2016 Preference Shares and 2017 Preference Shares

Without prejudice to the rights attached to 2016 Preference Shares and 2017 Preference Shares, each ordinary share entitles to a portion of the corporate profits
and assets in proportion to the portion of share capital that it represents.

In addition, each ordinary share gives the right to vote and be represented at General Meetings of Shareholders pursuant to the conditions provided by law and in
these articles of association. Ordinary shares, 2016 Preference Shares and 2017 Preference Shares (including shares of the Company that might be allocated for
free in the framework of a capital increase through the incorporation of reserves, issue premiums or profits) do not grant a double voting right pursuant to the last
paragraph of Article L. 225-123 of the French Commercial Code.

6

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
TRANSLATION FOR INFORMATION PURPOSES

Shareholders holding ordinary shares, 2016 Preference Shares and 2017 Preference Shares are only liable up to the nominal amount of the shares which they hold
and any request for funds beyond that amount is prohibited.

Ownership of ordinary shares, 2016 Preference Shares and 2017 Preference Shares automatically implies agreement to be bound by the Company’s by-laws and
the decisions of the General Meeting of Shareholders.

The  heirs,  creditors,  successors  or  other  representatives  of  the  shareholder  holding  ordinary  shares,  2016  Preference  Shares  or  2017  Preference  Shares  cannot
request seals to be placed on the Company’s assets and securities or request their distribution or sale by public auction, or to interfere with its management. In
order to exercise their rights, they should rely on company records and the decisions of the General Meeting of Shareholders.

Whenever it is necessary to hold several ordinary shares, 2016 Preference Shares or 2017 Preference Shares in order to exercise a right of any kind, in the case of
an exchange, regrouping or allocation of securities, or further to a share capital increase or decrease, merger or other corporate transaction, holders of single shares
or of less than the number of shares so required will only be able to exercise such right if they themselves collect and, as the case may be, purchase or sell, the
required number of securities.

However, the Company may, in the case of an exchange of securities further to a merger or demerger, a share capital reduction, the regrouping or division and
mandatory conversion of bearer into registered shares, or the distribution of securities deducted from reserves or in connection with a share capital reduction, or
the distribution or allocation of free shares, pursuant to a decision of the Executive Board, sell any securities in respect of which the persons entitled thereto have
not requested delivery subject to having carried out the publicity formalities provided by regulations at least two years beforehand.

As from the date of such sale, the prior securities or rights to distribution or allocation shall be cancelled as and when required, and their holders shall only be
entitled to the allocation of the net proceeds of sale of unclaimed securities.

II. 2016 Preference Shares

A. Rights attached to 2016 Preference Shares

2016 Preference Shares and the rights of holders thereof are governed by the applicable provisions of the French Commercial Code, in particular Articles 228-11
et seq. thereof.

The maximum number of 2016 Preference Shares that may be allocated is 7,500 shares.

Only the 2016 Preference Shares convertible into ordinary shares pursuant to the terms and conditions specified below benefit from a dividend and are entitled to
the reserves, applicable only from the date at which they become convertible. The 2016 Preference Shares that have become convertible will bear rights as from
the first day of the financial year preceding the financial year during which they become convertible. The amount of the dividend (and, if applicable, of the portion
of the reserves) to which each 2016 Preference Shares entitles is equal to the amount due in respect of an ordinary share, multiplied by the number of ordinary
share that can be received from the conversion of each 2016 Preference Shares.

2016 Preference Shares give no preferential subscription right to any capital increase or any operation granting a right on ordinary shares.

In the event of an operation taking place before the 2016 Preference Shares are converted pursuant to paragraph II.B below, the conversion ratio will be adjusted
pursuant to the provisions of Article L. 228-99, Paragraph 2, 3° and Paragraph 5 of the French Commercial Code.

With regards to the ownership of corporate assets, a 2016 Preference Shares gives right to a portion of the liquidation surplus in proportion to the portion of share
capital that it represents.

7

 
 
 
 
 
 
 
 
 
 
 
 
 
 
TRANSLATION FOR INFORMATION PURPOSES

Only the 2016 Preference Shares convertible into ordinary shares pursuant to the terms and conditions specified below grant the right to vote in the ordinary and
extraordinary general meetings of holders of ordinary shares, applicable only from the date at which they become convertible. The number of voting rights granted
by each 2016 Preference Share is equal to the number of ordinary shares that can be received from the conversion of each 2016 Preference Share.

2016 Preference Shares grant the right to vote in the special meetings of holders of 2016 Preference Shares. Holders of 2016 Preference Shares are grouped into a
special meeting for any proposed modification of the rights attached to 2016 Preference Shares. In addition, pursuant to the provisions of Article L. 228-17 of the
French Commercial Code, any proposed merger or demerger of the Company in which 2016 Preference Shares cannot be exchanged for shares with equivalent
particular rights will be subject to the approval of any relevant special meeting.

Special meetings can only make valid decisions if the holders of 2016 Preference Shares that are present or represented hold at least, when convened for the first
time, one third, and when convened for the second time, one fifth of the 2016 Preference Shares carrying the right to vote. If the capital is modified or adjusted,
the rights of holders of 2016 Preference Shares are adjusted so that their rights may be maintained pursuant to Article L. 228-99 of the French Commercial Code.
The other rights attached to 2016 Preference Shares are specified in the next paragraph.

B. Conversion of 2016 Preference Shares into ordinary shares

The issuance of 2016 Preference Shares may only be decided in the framework of an allocation of free shares in favour of the employees and/or executive officers
of the Company, pursuant to the provisions of Articles L. 225-97-1 of the French Commercial Code.

2016 Preference Shares will be definitively acquired by the beneficiaries after an acquisition period of one year from their allocation by the Executive Board and
subject to the beneficiary’s presence in the Company or its consolidated subsidiaries as an employee, executive officer or member of an executive or supervisory
body or, if applicable, of the equivalent thereof in foreign law. The “Acquisition Date” is defined as the end of the acquisition period of the Preference Shares.

However, in the event of invalidity of the beneficiary corresponding to classification in the second or third categories set forth by Article L. 341-4 of the French
Social Security Code (or the equivalent thereof in an applicable foreign law), the 2016 Preference Shares will be allocated definitively prior to the Acquisition
Date.

The 2016 Preference Shares become convertible in ordinary shares, either new or existing at the Company’s option, after the above-mentioned one-year vesting
period from their allocation by the Executive Board, followed by a two-year retention period from the definitive allocation (the “Retention Period”), under the
conditions set forth in Paragraphs 2 to 10 below. The “Expiry Date of the Retention Period” is defined as the end of the Retention Period.

However, in the event of invalidity of the beneficiary corresponding to classification in the second or third categories set forth by Article L. 341-4 of the French
Social Security Code (or the equivalent thereof in an applicable foreign law), the 2016 Preference Shares will be allocated definitively prior to the Acquisition
Date.

1. As from the first anniversary date of the Acquisition Date, 2016 Preference Shares will be freely transferable to a credit institution  in  the  framework  of  a

pledge agreement.

Pursuant to the provisions set forth in the Article L. 225-197-1 I., Paragraph 6 of the French Commercial Code, the 2016 Preference Shares will be freely
transferable in the event of invalidity of the beneficiary corresponding to classification in the second or third categories set forth by Article L. 341-4 of the
French Social Security Code, regardless of whether such invalidity occurs before or after the Acquisition Date.

2.

2016  Preference  Shares  may  only  be  converted  for  a  conversion  period  of  six  years  and  six  months  from  the  Expiry  Date  of  the  Retention  Period  (the
“Conversion Period”).

8

 
 
 
 
 
 
 
 
 
 
 
 
TRANSLATION FOR INFORMATION PURPOSES

3. During the Conversion Period, each holder of 2016 Preference Shares will have the right to convert each of his 2016 Preference Shares in ordinary shares,
either new or existing (at the Company’s option). The number of ordinary shares to which the conversion of one 2016 Preference Share will entitle will be
equal to the sum of (i) a number of ordinary shares determined according to the fulfilment of an internal condition (the “Internal Condition”) and a market
condition as defined below ((the “Market Condition”) (together the “Performance Criteria”).

The fulfilment of the Performance Criteria will give the right to convert each 2016 Preference Share in a maximum of 200 ordinary shares, i.e. a maximum of
100 ordinary shares under the Internal Condition and a maximum of 100 ordinary shares under the Market Condition.

It is specified that this conversion ratio thus determined will be adjusted in order to take into account the shares to be issued to preserve the rights of holders
of securities or other rights giving access to the share capital and holders of 2016 Preference Shares under legal and statutory requirements and Paragraph II.
above.

4. The Internal Condition in order to calculate the number of 2016 Preference Shares that can be converted will be determined as a function of the highest of the

following two alternative criteria:

a) The first criterion is a function of the consolidated collected turnover of the Company relating to a present or future partnership or licensing agreement,

cumulated over the period from 1 July 2016 to 30 June 2019 (the “Cash Revenues”):

(i)           If the Turnover is strictly inferior to 50 million euros, the conversion ratio under the Internal Condition will be equal to 0;

(ii)

If the Turnover is superior or equal to 50 million euros and inferior to 150 million euros, the conversion ratio under the Price Condition
will be equal to :
[(Turnover-50)/100]×100

(iii)

If the Cash Revenues are equal or superior to 150 million Euros, the conversion ratio under the Internal Condition will be equal to 100;

b) The second criterion is a function of the maturity of the portfolio of drug candidates developed by the Company during the three years before the Expiry
Date of the Retention Period. “Drug candidates developed by the Company” mean Lirilumab, Monalizumab and IPH4102. For each of these products:

(v)

(iv)         In the event of the authorization by the competent regulatory authority the United States or in Europe for the Company or one of its
partners to carry out a Phase III trial or a clinical trial with a view to register a product, the conversion ratio under the Internal Condition
will be equal to 50;
In the event of the authorization by the competent regulatory authority in the United States or in Europe for the Company or one of its
partners to carry out two Phases III trials or clinical trials with a view to register two products and/or two different indications for one
product, the conversion ratio under the Internal Condition will be equal to 75;
In the event of an acceptance from the European Medicines Agency (EMA) in Europe or the Food and Drug Administration (FDA) in the
United States to examine a filing by the Company or one of its partners of a marketing authorization request, the conversion ratio under
the Internal Condition will be equal to 100.

(vi)

5. The Market Condition in order to calculate the conversion ratio of 2016 Preference Shares into ordinary shares will be determined depending on the stock

market price of the Innate Pharma share:

The terms “Initial Price” mean the average closing price of the Innate Pharma share on Euronext Paris for the sixty trading days prior to the Allocation Date
by the Executive Board.

9

 
 
 
 
 
 
 
 
 
 
 
TRANSLATION FOR INFORMATION PURPOSES

The  terms  “Final  Price”  mean  the  highest  average  closing  price  of  the  Innate  Pharma  share  on  Euronext  Paris  over  a  period  of  sixty  consecutive  days
calculated at any time during the three years prior to the Expiry Date of the Retention Period.

The terms “High Price” means the Initial Price multiplied by two.

a)

If the Final Price is strictly inferior to the Initial Price, the conversion ratio under the Market Condition will be equal to 0;

b)

If the Final Price is between (i) a value equal or superior to the Initial Price and (ii) a value inferior to the High Price, the conversion ratio under the
Market Condition will be equal to:
[(Final Price / Initial Price) –1/ ] x 100

c)

If the Final Price is equal or superior to the High Price, the conversion ratio under the Market Condition will be equal to 100.

6. The right to convert 2016 Preference Shares into ordinary shares, as well as the right to vote in the general meetings of ordinary shares holders and the right to
the dividend and to a portion of the reserves attached to 2016 Preference Shares that have become convertible pursuant to Paragraph II. above, are subject to
the condition of the beneficiary’s presence in the Company or its consolidated subsidiaries as an employee, an executive officer or a member of an executive
or supervisory body or, if applicable, of the equivalent thereof in foreign law as at the Expiry Date of the Retention Period. In the event that such condition
ceases to be fulfilled, the Company may proceed at any moment to the redemption of 2016 Preference Shares in the conditions set forth in Paragraph 8. below.
It is specified that the provisions of this paragraph do not apply if the presence of the beneficiary in the Company or its consolidated subsidiaries ceases due to
death, invalidity or retirement.

7. The fulfilment of the Performance Criteria will be recorded in a meeting of the Executive Board as soon as practicable after the Expiry Date of the Retention

Period.

8.

2016 Preference Shares that cannot be converted into ordinary shares depending on the extent to which the Performance Criteria are fulfilled or if the presence
condition as at the Expiry Date of the Retention Period is not fulfilled, and 2016 Preference Shares that can be but will not have been converted at the end of
the Conversion Period, may be bought at any time by the Company (which is under no obligation to do so) at their nominal value.

9. At  the  end  of  the  Conversion  Period,  the  Company  will  have  the  possibility  to  proceed,  pursuant  to  applicable  legal  and  regulatory  provisions,  to  the
cancellation of 2016 Preference Shares that will have not been converted, including  those  that  it  will  have  bought.  The  share  capital  will  then  be  reduced
accordingly, and creditors will have the right to oppose such reduction in the conditions set forth in Article L. 225-205 of the French Commercial Code.

10. New ordinary shares resulting from the conversion of 2016 Preference Shares will be assimilated to existing ordinary shares, will bear rights as from the first
day of the financial year preceding the financial year during which they become convertible, and will grant to their holders, starting from their delivery, all the
rights attached to ordinary shares. They will be subject to a request for listing on the regulated market of Euronext Paris on the same listing line as ordinary
shares.

By way of derogation to the above, the allocation of 2016 Preference Shares can take place after the date of their allocation by the Executive Board and prior to
the Acquisition Date, in the event of invalidity of the beneficiary corresponding to classification in the second or third categories set forth by Article L. 341-4 of
the French Social Security Code, at the beneficiary’s request.

The Executive Board will record the conversion into ordinary shares of the 2016 Preference Shares for which the conversion fulfils the conditions set forth above,
as well as the number of ordinary shares resulting from the conversions of 2016 Preference Shares that have taken place, and will modify the by-laws accordingly,
in particular with regards to the breakdown of shares by category. This competence may be delegated to the Chairman of the Executive Board under the conditions
set forth by law.

10

 
 
 
 
 
 
 
 
 
 
 
 
TRANSLATION FOR INFORMATION PURPOSES

If the conversion of 2016 Preference Shares into ordinary shares results in a capital increase, such increase will be fully paid up at issue through the incorporation
of reserves, profits or issue premiums for the corresponding amount.

Shareholders will be informed of the conversions having taken place by the reports of the Executive Board and Statutory Auditors pursuant to Article R. 228-18 of
the  French  Commercial  Code.  These  supplementary  reports  will  be  made  available  to  the  shareholders  at  the  Company’s  registered  office  as  from  the  date  on
which each meeting is convened.

III. 2017 Preference Shares

A. Rights attached to 2017 Preference Shares

2017 Preference Shares and the rights of holders thereof are governed by the applicable provisions of the French Commercial Code, in particular Articles 228-11
et seq. thereof.

The maximum number of 2017 Preference Shares that may be allocated is 12,500 shares.

From  their  definitive  acquisition  until  the  date  at  which  they  become  convertible,  the  2017  Preference  Shares  grant  the  right  to  vote  in  the  ordinary  and
extraordinary general meetings of holders of ordinary shares on the basis of one voting right per 2017 Preference Share. As from the date on which they become
convertible,  the  number  of  voting  rights  to  which  each  2017  Preferred  Share  entitles  the  holder  becomes  equal  to  the  number  of  ordinary  shares  to  which  the
conversion of each 2017 Preferred Share entitles the holder.

2017 Preference Shares grant the right to vote in the special meetings of holders of 2017 Preference Shares. Holders of 2017 Preference Shares are grouped into a
special meeting for any proposed modification of the rights attached to 2017 Preference Shares. In addition, pursuant to the provisions of Article L. 228-17 of the
French Commercial Code, any proposed merger or demerger of the Company in which 2017 Preference Shares cannot be exchanged for shares with equivalent
particular rights will be subject to the approval of any relevant special meeting.

Special meetings can only make valid decisions if the holders of 2017 Preference Shares that are present or represented hold at least, when convened for the first
time, one third, and when convened for the second time, one fifth of the 2017 Preference Shares carrying the right to vote.

From  their  definitive  acquisition  until  the  date  at  which  they  become  convertible,  the  2017  Preference  Shares  benefit  from  a  dividend  and  are  entitled  to  the
reserves. The amount of the dividend (and, if applicable, of the portion of the reserves) to which each 2017 Preference Shares entitles is equal to the amount due in
respect of an ordinary share. To this end, the 2017 Preference Shares will bear rights as from the first day of the financial year preceding the financial year during
which  they  are  definitively  acquired.  As  from  the  date  at  which  they  become  convertible,  the  amount  of  the  dividend  (and,  if  applicable,  of  the  portion  of  the
reserves) to which each 2017 Preference Shares entitles is equal to the amount due in respect of an ordinary share, multiplied by the number of ordinary share that
can be received from the conversion of each 2017 Preference Shares.

With regards to the ownership of corporate assets, a 2017 Preference Shares gives right to a portion of the liquidation surplus in proportion to the portion of share
capital that it represents.

2017  Preference  Shares  give  preferential  subscription  rights  to  any  capital  increase  or  any  operation  granting  a  right  on  ordinary  shares,  on  the  basis  of  one
preferential subscription right per 2017 Preferred Share.

In  the  event  of  a  capital  depreciation  or  reduction,  a  change  in  the  distribution  of  profits,  an  allocation  of  free  shares,  or  the  incorporation  into  the  capital  of
reserves, profits or share premiums, distribution of reserves or any issue of capital securities or securities giving the right to the allocation of capital securities with
a subscription right reserved for shareholders before the 2017 Preferred Shares are convertible under the conditions provided below, the conversion ratio will be
adjusted to take into account this operation pursuant to the provisions of Article L. 228-99, Paragraph 2, 3° and Paragraph 5 of the French Commercial Code.

B. Conversion of 2017 Preference Shares into ordinary shares

The issuance of 2017 Preference Shares may only be decided in the framework of an allocation of free shares in favour of the employees and/or executive officers
of the Company, pursuant to the provisions of Articles L. 225-97-1 of the French Commercial Code.

2017 Preference Shares will be definitively acquired by the beneficiaries after an acquisition period of one year from their allocation by the Executive Board and
subject to the beneficiary’s presence in the Company or its consolidated subsidiaries as an employee, executive officer or member of an executive or supervisory
body or, if applicable, of the equivalent thereof in foreign law. The “Acquisition Date”  is  defined  as  the  end  of  the  acquisition  period  of  the  2017  Preference
Shares.

However, in the event of invalidity of the beneficiary corresponding to classification in the second or third categories set forth by Article L. 341-4 of the French
Social Security Code (or the equivalent thereof in an applicable foreign law), the 2017 Preference Shares will be allocated definitively prior to the Acquisition
Date.  In  the  event  of  the  death  of  the  beneficiary,  in  accordance  with  the  provisions  of  Article  L.  225-197-3  of  the  French  Commercial  Code,  the  heirs  or
successors of the beneficiary may, if they so wish, request the definitive allocation of the 2017 Preferred Shares to them within six months of the date of death. In
the event of retirement, the beneficiaries will retain their right to the definitive allocation of the 2017 Preferred Shares although they are no longer bound by an
employment contract.

1.             The 2017 Preference Shares become convertible in ordinary shares, either new or existing at the Company’s option, after the above-mentioned one-year
vesting period from their allocation by the Executive Board, followed by a two-year retention period from the definitive allocation (the “Retention Period”), under
the conditions set forth in Paragraphs 2 to 13 below. The “Expiry Date of the Retention Period” is defined as the end of the Retention Period.

As  an  exception  to  the  above,  in  the  event  of  a  public  tender  or  exchange  offer,  the  final  results  of  which  are  announced  no  later  than  the  Expiry  Date  of  the
Retention Period as defined above, the 2017 Preferred Shares will become convertible no later than (i) the first anniversary of the Definitive Allocation (if such an
offer occurs before such anniversary and in such a way that the Retention Period lasts at least one year), or (ii) the date of announcement of the final results of
such an offer (if such an offer occurs after the anniversary) (the "Amended Expiry Date of the Retention Period").

2.             As from the first anniversary date of the Acquisition Date, 2017 Preference Shares will be freely transferable to a credit institution in the framework of a
pledge agreement.

Pursuant  to  the  provisions  set  forth  in  the  Article  L.  225-197-1  I.,  Paragraph  6  of  the  French  Commercial  Code,  the  2017  Preference  Shares  will  be  freely
transferable in the event of invalidity of the beneficiary corresponding to classification in the second or third categories set forth by Article L. 341-4 of the French
Social Security Code, regardless of whether such invalidity occurs before or after the Acquisition Date.

In the event of the beneficiary's death, whether during the vesting period or the Retention Period, his heirs will no longer be required to comply with this non-
transferability commitment, so that the 2017 Preferred Shares for which they have requested the definitive allocation will freely become transferable.

3.             2017 Preference Shares may only be converted for a conversion period of six years and six months from the Expiry Date of the Retention Period (the
“Conversion Period”), provided however that in the event of a public tender or exchange offer whose final results are announced no later than the Expiry Date of
the Retention Period, the Conversion Period shall commence from the Amended Expiry Date of the Retention Period for such a period that, together with the
Retention Period, it represents a total duration of eight years and six months from the Acquisition Date.

4.             During the Conversion Period, each holder of 2017 Preference Shares will have the right to convert each of his 2017 Preference Shares in ordinary
shares, either new or existing (at the Company’s option). The number of ordinary shares to which the conversion of one 2017 Preference Share will entitle will be
equal to a number of ordinary shares determined according to the fulfilment of a market condition as defined below (the “Market Condition”).

TRANSLATION FOR INFORMATION PURPOSES

5.             The Market Condition in order to calculate the conversion ratio of 2017 Preference Shares into ordinary shares will be determined based on the relative
performance of the Innate pharma share.

The term “Initial Price” means the average closing price of the Innate Pharma share on Euronext Paris for the sixty trading days prior to the date of the General
Meeting.

The  term  “Final  Price”  means  (i)  the  highest  average  closing  price  of  the  Innate  Pharma  share  on  Euronext  Paris  over  a  period  of  sixty  consecutive  days,
calculated at any time during the twelve months prior to the Expiry Date of the Retention Period, or (ii) in the event of a public tender or exchange offer whose
final results are announced no later than the Expiry Date of the Retention Period, the price at which this public tender offer is made (or, in the case of a public
exchange offer only, the price by transparency by applying the exchange ratio to the closing price of the bidder's share on the day before the Amended Expiry Date
of the Retention Period).

a) If the Final Price is inferior or equal to the Initial Price, the conversion ratio will be equal to 0;

b) If the Final Price is comprised between the Initial Price and € 30, the conversion ratio will be equal to:
100 x [(Final Price – Initial Price) / (30 – Initial Price)], rounded up to the nearest whole number

c) If the Final Price is equal or superior to € 30, the conversion ratio will be equal to 100.

However,  if  between  the  date  of  the  General  Meeting  and  the  Expiry  Date  of  the  Retention  Period  (or,  as  the  case  may  be,  the  Amended  Expiry  Date  of  the
Retention Period), one of the Reference Indexes (as defined below) were to experience a Significant Variation (as defined below), then the Executive Board will
have the possibility to adjust the Initial Price and/or the Final Price to neutralize the exogenous impact of such a Significant Variation. The Executive Board shall,
in this case, appoint a recognized independent expert to assist the Executive Board in the determination of such adjustments.

The term “Reference Indexes” means the following stock market indexes: SBF 120, CAC 40, Next Biotech and NBI (NASDAQ Biotechnology Index). If one of
these indexes were to be no longer available, the Executive Board can choose a replacement index.

The term “Significant Variation” means one or the other of the following events for the relevant index:

-

-

the average of the closing value for the index over the sixty consecutive trading days prior to the Expiry Date of the Retention Period (or, as the case may be,
the Amended Expiry Date of the Retention Period) is inferior or  equal  to  90%  of  the  average  of  the  closing  value  for  the  index  over  the  sixty  consecutive
trading days prior to the General Meeting ;

the average of the closing value for the index over a sixty consecutive trading days period at any time between the date of the General Meeting and the Expiry
Date of the Retention Period (or, as the case may be, the Amended Expiry Date of the Retention Period), is inferior or equal to 80% of the average of the
closing value for the index over another sixty consecutive trading days period at any time between the date of the General Meeting and the Expiry Date of the
Retention Period (or, as the case may be, the Amended Expiry Date of the Retention Period).

6.             The right to convert 2017 Preference Shares into ordinary shares, as well as the right to vote in the general meetings of ordinary shares holders and the
right to the dividend and to a portion of the reserves attached to 2017 Preference Shares that have become convertible pursuant to Paragraph III A. above, are
subject  to  the  condition  of  the  beneficiary’s  presence  in  the  Company  or  its  consolidated  subsidiaries  as  an  employee,  an  executive  officer  or  a  member  of  an
executive or supervisory body or, if applicable, of the equivalent thereof in foreign law as at the Expiry Date of the Retention Period (or, as the case may be, the
Amended Expiry Date of the Retention Period). In the event that such condition ceases to be fulfilled, the Company may proceed at any moment to the redemption
of 2017 Preference Shares in the conditions set forth in Paragraph 8. below. It is specified that the provisions of this paragraph do not apply if the presence of the
beneficiary in the Company or its consolidated subsidiaries ceases due to death, invalidity or retirement.

13

 
 
 
 
 
 
 
 
 
 
 
 
TRANSLATION FOR INFORMATION PURPOSES

7.             The  fulfilment  of  the  Market  Condition  will  be  recorded  in  a  meeting  of  the  Executive  Board  as  soon  as  practicable  after  the  Expiry  Date  of  the
Retention Period (or, as the case may be, the Amended Expiry Date of the Retention Period).

8.             2017 Preference Shares that cannot be converted into ordinary shares depending on the extent to which the Market Condition is fulfilled or if the
presence condition as at the Expiry Date of the Retention Period (or, as the case may be, the Amended Expiry Date of the Retention Period) is not fulfilled, and
2017 Preference Shares that can be but will not have been converted at the end of the Conversion Period, may be bought at any time by the Company (which is
under no obligation to do so) at their nominal value.

9.             At the end of the Conversion Period, the Company will have the possibility to proceed, pursuant to applicable legal and regulatory provisions, to the
cancellation  of  2017  Preference  Shares  that  will  have  not  been  converted,  including  those  that  it  will  have  bought.  The  share  capital  will  then  be  reduced
accordingly, and creditors will have the right to oppose such reduction in the conditions set forth in Article L. 225-205 of the French Commercial Code.

10.          New ordinary shares resulting from the conversion of 2017 Preference Shares will be assimilated to existing ordinary shares, will bear rights as from the
first day of the financial year preceding the financial year during which they will be converted, and will grant to their holders, starting from their delivery, all the
rights attached to ordinary shares. They will be subject to a request for listing on the regulated market of Euronext Paris on the same listing line as ordinary shares.

By way of derogation to the above, the allocation of 2017 Preference Shares can take place after the date of their allocation by the Executive Board and prior to
the Acquisition Date, in the event of invalidity of the beneficiary corresponding to classification in the second or third categories set forth by Article L. 341-4 of
the French Social Security Code, at the beneficiary’s request.

11.          The Executive Board will record the conversion into ordinary shares of the 2017 Preference Shares for which the conversion fulfils the conditions set
forth above, as well as the number of ordinary shares resulting from the conversions of 2017 Preference Shares that have taken place, and will modify the by-laws
accordingly, in particular with regards to the breakdown of shares by category. This competence may be delegated to the Chairman of the Executive Board under
the conditions set forth by law.

12.          If the conversion of 2017 Preference Shares into ordinary shares results in a capital increase, such increase will be fully paid up at issue through the
incorporation of reserves, profits or issue premiums for the corresponding amount.

13.          Shareholders will be informed of the conversions having taken place by the reports of the Executive Board and Statutory Auditors pursuant to Article R.
228-18 of the French Commercial Code. These supplementary reports will be made available to the shareholders at the Company’s registered office as from the
date on which each general meeting is convened.

ARTICLE 13 – Usufruct / Bare Ownership

The shares are not divisible with respect to the Company.

Co-owners of shares must arrange to be represented vis-a-vis the Company by one of them only, who will be considered as the sole holder, or by a sole agent. In
the case of disagreement, a sole agent may be appointed by the courts at the request of the most diligent co-owner.

Unless the Company has been notified of an agreement to the contrary, usufruct shareholders validly represent bare owners vis-à-vis the Company. The right to
vote is held by the usufruct shareholder in Ordinary Meeting of Shareholders and by the bare owner in Extraordinary Meeting of Shareholders.

Unless otherwise agreed by the parties, where shares are encumbered by a usufruct interest, the preferential right to subscription attached thereto is held by the
bare owner.

COMPANY MANAGEMENT AND SUPERVISION

ARTICLE 14 – Management Structure

The Company is managed by an Executive Board which exercises its duties under the supervision of a Supervisory Board.

ARTICLE 15 – Composition of the Executive Board

I.       The Executive Board consists of at least two members and five members at most.

II.       Members of the Executive Board are appointed by the Supervisory Board.

The members of the Supervisory Board appoint one of the members of the Executive Board as Chairman of the Executive Board for the duration of his term of
office as a member of the Executive Board. The Chairman of the Executive may be dismissed by the Supervisory Board.

Members of the Executive Board must be natural persons, failing which the appointment shall be null and void. They may be chosen from non-shareholders. They
may be French nationals or of foreign nationality.

Members of the Executive Board may be dismissed by the Supervisory Board of the Meeting of Shareholders. They may resign at any time.

If a member of the Executive Board has entered into an employment contract with the Company, his dismissal, resignation or the expiry of his term of office as a
member of the Executive Board will not cause such contract to be terminated.

The  Executive  Board  is  appointed  for  a  term  of  three  years.  If  a  post  is  vacant,  the  Supervisory  Board  must  make  an  appointment  to  fill  the  post  within  two
months.

However, the terms of office of the members of the Executive Board who were duly appointed for six years by the Supervisory Board of 13 June 2005, pursuant to
the provisions of the articles of association which were then applicable, shall continue to the end of their initial term and be renewed at the annual meeting of
shareholders called to decide on the accounts of the financial year closing 31 December 2010.

The replacement is appointed for the remaining term until the renewal of the Executive Board. Members of the Executive Board may be reappointed.

Board member delegated to such effect, at the place decided by the person convening the meeting.

In order for deliberations to be valid, the majority of the members of the Executive Board must be physically present. However, members of the Executive Board
who attend Executive Board meetings by video-conference or any other means of telecommunication in compliance with the statutory and regulatory provisions
applicable to corporations with a Board of Directors management structure, are deemed to be present.

Chairman or by a member of the Executive Board delegated for this purpose. Following dissolution of the Company, they are certified by one of the liquidators or
the sole liquidator.

ARTICLE 16 - Powers of the Executive Board

I.       The Executive Board has the widest of powers to act in all circumstances in the name of the Company. It exercises its powers within the scope of the
corporate purposes, subject to the powers which are expressly granted by law to the Supervisory Board and the Meeting of Shareholders, and, as the case may be,
within the limit of the restrictions on powers decided by the Supervisory Board.

In its relations with third parties, the Company is bound by the actions of the Executive Board even where these are outside of the scope of the corporate purposes,
unless  it  proves  that  the  third  party  was  aware  that  the  actions  exceeded  such  purposes  or  if  it  could  not  have  failed  to  be  aware  of  this  in  view  of  the
circumstances; publication of the articles of association not in itself constituting sufficient evidence thereof.

The  Chairman  of  the  Executive  Board,  or,  as  the  case  may  be,  the  Chief  Executive  Officer,  ,  represents  the  Company  in  its  relations  with  third  parties.  The
Supervisory Board may grant the same authority to represent the Company to one or more other Executive Board members, who in that case will be referred to as
managing directors. The Chairman of the Executive Board and the managing director (s), if any, may designate any agent which they choose to exercise specific
powers.

ARTICLE 17 – Composition of the Supervisory Board

I.       The Executive Board is supervised by a Supervisory Board composed of a minimum of three members and a maximum of eighteen members, subject to the
exceptions provided by law in such respect in the event of a merger.

Members of the Supervisory Board are appointed from among natural persons or legal entities that are shareholders by the Ordinary Meeting of Shareholders,
which may dismiss them at any time. However, in the case of a merger or demerger, an Extraordinary Meeting of Shareholders may appoint the members of the
Supervisory Board.

No member of the Supervisory Board may be a member of the Executive Board.

The  number  of  the  members  of  the  Supervisory  Board  who  have  reached  seventy  (70)  years  of  age  may  not  be  greater  than  one  third  of  the  members  of  the
Supervisory  Board  in  office.  Where  such  limitation  concerning  the  age  of  members  of  the  Supervisory  Board  is  exceeded,  the  most  elderly  member  of  the
Supervisory Board is deemed to have automatically resigned.

II.       The duration of the terms of office of the members of the Supervisory Board is two years. It expires at the close of the Meeting of Shareholders called to
decide on the financial statements for the preceding year and which is held during the year in which their appointment expires.

Members of the Supervisory Board may be reappointed.

They may be dismissed at any time by an Ordinary Meeting of Shareholders.

III.       Members of the Supervisory Board may be natural persons or legal entities. Legal entities must, at the time of their appointment, designate a permanent
representative who will be subject to the same conditions and obligations and who will incur the same liabilities provided by law as if he were a member of the
Council in his own name, without prejudice to the joint and several liability of the legal entity he represents.

If a legal entity dismisses its representative, it must appoint a replacement at the same time. This rule also applies in the case of the death, resignation or long-term
prevention of the permanent representative from exercising his duties.

A natural person who accepts an appointment and exercises as a member of the Supervisory Board thereby has the obligation to confirm at any time on oath, that
he satisfies the limitation required by law with respect to the combining the post of member of the Supervisory Board and member of the Executive Board of
corporations.

IV.              Appointments  which  are  made  by  the  Supervisory  Board  in  accordance  with  the  foregoing  are  subject  to  ratification  by  the  next  following  Ordinary
Meeting of Shareholders. If such appointments are not ratified, the deliberations made and actions previously carried out by the Supervisory Board nevertheless
remain valid.

If the number of the members of the Council becomes less than the statutory minimum, the Executive Board must immediately convene an Ordinary Meeting of
Shareholders to appoint members to complete the Council.

A member of the Supervisory Board appointed to replace another member shall only remain in office for the remaining term of office of his predecessor.

V.       Each member of the Supervisory Board must own one share in the Company.

If a member of the Supervisory Board does not own the required number of shares on the date of his appointment or if, during his term of office he ceases to own
such number, he shall be deemed to have automatically resigned if he has not rectified this situation within six months.

of the voting rights or, in the case of a corporate shareholder, the company controlling it within the meaning of Article L. 233-3 of the Commercial Code with

The same rule applies to agreements in which one of the persons referred to in the previous paragraph has an indirect interest or for which it has dealt with the

TRANSLATION FOR INFORMATION PURPOSES

The prior approval of the Supervisory Board is substantiated by justifying of the interest of entering the agreement for the Company, in particular by specifying the
financial conditions that apply thereto.

The preceding provisions do not apply to agreements entered into in the ordinary course of business and under normal conditions, nor to agreements entered into
between two companies, one of which holds, directly or indirectly, the entire share capital of the other company, excluding if applicable the minimum number of
shares necessary to comply with the requirements of Article 1832 of the French Civil Code or Articles L. 225-1 and L. 226-1 of the French Commercial Code.

TITLE V
STATUTORY AUDITORS

ARTICLE 25 - Statutory Auditors

One or more statutory auditors perform an audit of the Company, in the accordance with statutory requirements.

The Statutory Auditors are appointed by the Ordinary Meeting of Shareholders on proposal by the Supervisory Board, for six financial years. They may always be
re-appointed.  They  may  be  dismissed  by  the  aforesaid  Meeting  of  Shareholders  in  the  event  that  they  commit  a  fault  or  are  prevented  from  carrying  out  their
duties.

If the Meeting of Shareholders does not appoint the Statutory Auditor(s) or if one or more appointed Statutory Auditors are prevented or refuse to carry out their
duties, they, or their replacement(s), are appointed by an order of the Commercial Court with jurisdiction over the area in which the Company is based on petition
of any interested person, with the Executive Board duly convened.

The Statutory Auditor appointed by the Meeting of Shareholders to replace another shall only remain in office for the remaining term of office of his predecessor.
If the Meeting of Shareholders appoints several Statutory Auditors, they may act together or separately but they must draft a joint report.

One or more shareholder(s) with a shareholding of at least 5% may apply to the courts to dismiss one or more of the Statutory Auditors appointed by the Meeting
of  Shareholders  and  request  the  appointment  of  one  or  more  Statutory  Auditors  who  will  exercise  their  duties  instead  of  them.  If  their  request  is  granted,  the
Statutory Auditors so appointed shall exercise their duties until the Statutory Auditors appointed by the Meeting of Shareholders take up their posts.

The Statutory Auditors certify that the annual financial statements are in due form and give a true and fair view of the result of the operations of the preceding

TITLE VI
SHAREHOLDERS’ MEETINGS

A –Provisions Applying
to all Meetings of Shareholders

ARTICLE 26 - Meetings

A duly constituted Meeting of Shareholders represents all the shareholders.

Its deliberations effected in accordance with the law and the articles of association are binding on all the shareholders, even those who were absent, dissenting or
without legal standing.

There are three kinds of meeting, depending on the purpose of the proposed resolutions:

-

-

-

Ordinary Meeting of Shareholders,

Extraordinary Meeting of Shareholders,

Special Meeting of Shareholders of holders of a specific category of share.

ARTICLE 27 – Convening Meetings

Shareholders’ Meetings are convened by the Executive Board, or failing that, the Supervisory Board. They may also be convened by the Statutory Auditor(s) or by
an agent appointed by the court in accordance with the procedures and conditions provided by statute.

During liquidation, Shareholders’ Meetings are convened by the liquidator.

Shareholders’ Meetings are held at the registered office, in any other place of the same department indicated in the convocation notice or in Paris.

Notice of the meeting is published in the Bulletin des Annonces Légales Obligatoires (BALO) (Mandatory Legal Notice Bulletin) at least thirty-five days prior to
which a meeting is held. In addition to the information relating to the Company, it also, in particular, sets out the agenda of the Meeting and the draft text of the
resolutions which will be proposed. Subject to particular legal requirements, requests for the inclusion of draft resolutions on the agenda must be sent at the latest
on  the  publication  date  of  the  notice  of  the  meeting  and  up  to  twenty-five  days  prior  to  the  Shareholders’  Meeting;  this  deadline  is  twenty  days  from  the
publication date of the notice when the notice is published more than forty-five days prior to the Shareholders’ Meeting.

Subject to particular legal requirements, invitations to meetings are made at least fifteen days prior to the date of the meeting by a notice published in both the
legal notice journal of the administrative department in which the registered office is located and in the Bulletin des Annonces Légales Obligatoires (BALO).

However, holders of registered shares having held shares for at least one month as at the date of the last of the published notices must be convened individually by
ordinary  letter  (or  by  registered  letter  if  they  have  requested  this  and  advanced  the  costs)  sent  to  their  last  known  address.  Such  notice  may  also  be  sent  by
electronic  communication  instead  of  such  postal  dispatch,  to  any  shareholder  who  has  so  requested  beforehand  by  registered  mail  return  receipt  requested,  in
accordance  with  statutory  and  regulatory  requirements,  indicating  his  email  address.  Such  shareholder  may  send  a  request  to  the  Company  at  any  time  by
registered letter with acknowledgement of receipt for the aforementioned method of telecommunication to be replaced by postal dispatch in the future.

The invitation should contain the following information:

-

-

the identity of the Company;

the date, time and place of the meeting;

22

 
 
 
 
 
 
 
  
 
 
 
 
 
 
 
 
 
 
TRANSLATION FOR INFORMATION PURPOSES

-

-

the nature of the meeting; and

the agenda of the meeting.

It must also state the conditions in which shareholders may vote by correspondence and the place and conditions pursuant to which they may procure forms for
voting by correspondence.

The invitation may be sent, as the case may be, together with proxy form and a correspondence voting form, pursuant to the conditions set out in Article 30. I of
these Articles of Association, or with a correspondence voting form only, pursuant to the conditions set out in Article 30. II of these Articles of Association.

If a Shareholders’ Meeting has not been able to deliberate due to the required quorum not being reached, a second Shareholders’ Meeting is convened with at least
ten days’ advance notice, in the same manner as the first meeting. The invitation notice or letters for such second Shareholders’ Meeting state the date and agenda
of the first meeting.

ARTICLE 28 - Agenda

The agenda of a Meeting of Shareholders is decided by the person convening the meeting.

One  or  more  shareholders  representing  at  least  the  percentage  of  share  capital  determined  by  statute  and  acting  pursuant  to  statutory  conditions  and  within
statutory time periods, may request items or draft resolutions to be included on the agenda of the Meeting by registered mail with confirmation of receipt.

The Meeting of Shareholders cannot deliberate on an issue which has not been included on the agenda and such agenda cannot be modified on second convocation
of a Meeting of Shareholders. The Meeting of Shareholders may, however, in any circumstances, dismiss one or several members of the Supervisory Board and
effect their replacement.

ARTICLE 29 – Participation of Shareholders in Meeting of Shareholders

All shareholders are entitled to attend Shareholders’ Meetings and take part in deliberations:

(i)

either personally; or

(ii)

by giving a proxy to another shareholder or to his spouse; or

(iii)

by sending a blank proxy to the Company; or

(iv)

by voting by correspondence; or

(v)

by videoconference or by another means of telecommunication in accordance with the applicable statutory and regulatory provisions.

Participation in shareholders’ meetings in any manner is dependent on the registration or inscription of shares under the conditions and within the deadlines set in
the current regulations.

The final date for the return of correspondence voting forms is determined by the Executive Board and indicated in the notice of the meeting published in the
Bulletin des Annonces Légales et Obligatoires (BALO). This date cannot be prior to three days before the Shareholders’ Meetings.

If  a  shareholder  is  present  at  a  Shareholders’  Meeting,  any  prior  vote  by  correspondence  will  have  no  effect  for  the  purposes  of  the  aforesaid  Shareholders’
Meeting.

If  both  a  proxy  form  and  a  correspondence  voting  form  are  returned,  the  proxy  form  will  be  taken  into  account,  subject  to  the  votes  expressed  in  the
correspondence voting form.

ARTICLE 31 – Attendance Register

An attendance register is kept for each Meeting of Shareholders containing the information required by law.

This attendance register, duly signed by the shareholders that are present, the agents and shareholders participating by video-conference or by another means of
telecommunication in compliance with statutory and regulatory requirements, and to which are attached the powers of attorney granted to each agent and, as the
case may be, the correspondence voting forms, is certified by the secretariat of the Meeting of Shareholders.

Meeting of Shareholders are chaired by the Chairman of the Supervisory Board, the Vice-Chairman or a member of the Supervisory Board delegated for such
purpose by the aforesaid Council. Failing that, the Meeting of Shareholders elects its Chairman itself.

The two shareholders present with the greatest number of votes both on in their own right and as agents, and who accept such assignment, shall act as vote tellers.

The secretariat composed as such appoints a Secretary, who may be selected from outside of the shareholders.

ARTICLE 32 – Quorum

In Ordinary and Extraordinary Meeting of Shareholders, the quorum is calculated on the basis of all the shares making up the share capital and, in Special Meeting
of Shareholders, all the shares of the relevant category, less shares stripped of their voting rights pursuant to statutory provisions.

The voting rights attached to shares are proportional to the portion of share capital which they represent. Each share entitling its holder to an interest in the capital
or to beneficial enjoyment carries one vote.

In the case of a vote by correspondence, only completed forms received by the Company at least three days prior the Meeting of Shareholders shall be taken into
account for the calculation of the quorum.

Forms which do not indicate which way to vote, or which indicate an abstention, are considered as negative votes.

ARTICLE 33 - Minutes

The deliberations of the Meeting of Shareholders are recorded in minutes drafted in a special register held at the registered office and signed by the members of
the secretariat.

Copies or extracts of such minutes are certified either by the Chairman of Vice-Chairman of the Supervisory Board or by a member of the Executive Board or by
the Secretary of the Meeting. If the Company is wound up, they may be validly certified by the liquidator(s).

ARTICLE 34 – Communication of Documents

Any shareholder is entitled to receive, and the Executive Board is bound to send or provide him with the documents he requires to come to an informed decision
and have an informed judgement on the management and running of the Company.

The nature of these documents and the conditions in which they are sent or provided to shareholders are determined by regulations in force.

25

 
 
 
 
 
  
 
 
 
 
  
 
 
  
 
 
 
TRANSLATION FOR INFORMATION PURPOSES

In exercising its right to receive documents, each shareholder or his agent may be assisted by a court-registered expert.

The exercise of the right to receive documents includes the right to make copies, except with respect to inventories.

B – Provisions Specific to
Ordinary Meetings of Shareholders

ARTICLE 35 – Ordinary Meeting of Shareholders

An Ordinary Meeting of Shareholders may make any decision other than one which directly or indirectly modifies the Articles of Association.

Ordinary Meetings of Shareholders are held at least once a year, within six months of the end of each financial year, to decide on the financial statements for such
financial year, subject to the extension of such period by an order of the President of the Commercial Court on petition from the Executive Board.

They are called on an extraordinary basis every time it may be in interests of the Company to do so.

When convened for the first time, Ordinary Meetings of Shareholders can only make valid decisions if the shareholders that are present, represented or voting by
correspondence hold at least one fifth of the shares carrying the right to vote.

When convened for the second time, there is no quorum requirement if the original agenda has not been modified.

Ordinary  Meetings  of  Shareholders  make  decisions  on  the  basis  of  the  majority  of  the  votes  of  the  shareholders  that  are  present,  represented  or  voting  by
correspondence.

C - Provisions Specific to
Extraordinary Meetings of Shareholders

ARTICLE 36 – Extraordinary Meetings of Shareholders

An amendment to any provision of the Articles of Association and, in particular, the transformation of the Company into another form of company may only be
decided  by  an  Extraordinary  Meeting  of  Shareholders.  An  Extraordinary  Meeting  of  Shareholders  cannot,  however,  increase  the  undertakings  of  shareholders,
subject to operations as a result of regrouping shares in a due and proper manner.

When convened for the first time, Extraordinary Meeting of Shareholders can only make valid decisions if the shareholders that are present, represented or voting
by correspondence hold at least a quarter of the shares carrying the right to vote, and when convened for the second time, one fifth of the shares carrying the right
to vote. If the latter quorum is not obtained, the second Meeting may be adjourned for a maximum of two months from the date at which it was convened.

An Extraordinary Meeting of Shareholders makes decisions on the basis of a majority of two-thirds of the votes held by shareholders that are present, represented
or  voting  by  correspondence  or  participating  in  the  Meeting  by  video-conference  or  another  method  of  telecommunication  in  accordance  with  statutory  and
regulatory provisions.

By  statutory  derogation  from  the  preceding  provisions,  if  the  share  capital  is  increased  by  the  incorporation  of  profits,  reserves  or  issue  premiums,  the
Extraordinary Meeting of Shareholders may make decisions at the quorum and majority required for Ordinary Meeting of Shareholders.

26

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
TRANSLATION FOR INFORMATION PURPOSES

Moreover, where an Extraordinary Meeting of Shareholders is convened to deliberate on the approval of a contribution in kind or the grant of a specific benefit,
the shares of the contributing party or beneficiary shall not be taken into account in calculating the majority. The contributing party or beneficiary cannot vote
either in his own right or as an agent.

D - Provisions Specific to
Special Meetings of Holders of a Category of Shares

ARTICLE 37 – Special Meeting

If there are several categories of shares, the rights attached to shares of any such category cannot be modified in any way without having been duly voted upon by
an Extraordinary Meeting of Shareholders open to all shareholders and also having been voted upon by a Special Meeting open only to holders of the relevant
category of shares.

When  convened  for  the  first  time,  Special  Meetings  of  Shareholders  can  only  make  valid  decisions  if  the  shareholders  that  are  present,  represented,  voting  by
correspondence or taking part in the Meeting by video-conference or any other means of telecommunication in accordance with statutory or regulatory provisions,
hold at least a third of the shares carrying the right to vote, and when convened for the second time, one fifth of the shares carrying the right to vote and for which
a modification of the attached rights is being proposed. Failing that, the second meeting may be adjourned by a maximum of two months from the date at which it
was convened.

Special Meetings of Shareholders make decisions at a two-thirds majority of the votes of shareholders that are present or represented.

TITLE VII
FINANCIAL YEAR – ANNUAL FINANCIAL STATEMENTS
APPROPRIATION AND DISTRIBUTION OF PROFITS

ARTICLE 38 – Financial Year

The financial year begins on 1st January of each year and ends on 31st December.

ARTICLE 39 - Accounts

Accounts of corporate operations are kept in due form in accordance with the law and usual business practice.

At the end of each financial year, the Executive Board shall draw up an inventory of the various assets and liabilities as at such date. It shall also prepare the
balance sheet describing the assets and liabilities, the income statement summarising the income and charges for the financial year and the notes to the financial
statements which complete and comment on the information provided in the balance sheet and income statement.

The Executive Board shall present such documents to the Supervisory Board within three months of the end of the financial year, for the purposes of verification
and supervision.
It shall prepare the management report on the situation of the Company during the preceding financial year.

All such documents shall be made available to the Statutory Auditors pursuant to the conditions specified by law.

27

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
TRANSLATION FOR INFORMATION PURPOSES

ARTICLE 40 – Appropriation of Profits

The income statement which summarises the income and charges for the financial year, after depreciation and provisions have been deducted, indicates the profit
or loss of the financial year by setting forth the difference between these two amounts.

Five per cent. of the year's profit less previous losses, as the case may be, is allocated to the statutory reserve. Such allocation shall no longer be necessary once
the aforesaid reserve reaches one tenth of the share capital, but will become necessary again if for any reason whatsoever the reserve falls below one tenth.

Distributable earnings consist of the net income of the financial year, less previous losses and amounts added to the reserve in accordance with the law or the
Articles of Association, plus retained earnings.

Moreover, the Meeting of Shareholders may decide to distribute amounts deducted from the reserves which are available to it, expressly indicating the reserves
from which the withdrawals are to be made. However, dividend is paid out in priority from the distributable income of the financial year.

Except in the case of a reduction in share capital, no distribution may be made to shareholders if shareholders’ equity is, or would become as a result of such
distribution, less than the share capital plus the reserves which the law or the Articles of Incorporation do not allow to be distributed.

After the financial statements have been approved and the existence of distributable income has been acknowledged, the Meeting of Shareholders shall determine
the part to be allocated to shareholders as dividends, in proportion to the number of shares held by each.

However, after the allocation of the amounts required by law to the reserve, the Meeting of Shareholders may decide to allocate all or part of the distributable
income to a retained earnings account or to any general or special reserve account.

Any losses are deducted from profits from previous years until such losses are extinguished or they are carried over.

The Executive Board may decide to distribute interim dividends prior to the approval of the financial statements of the financial year, pursuant to the conditions
determined or authorised by law. The amount of such instalments cannot exceed the amount of earnings as defined by law.

ARTICLE 41 - Dividends

I.       The procedure for the payment of dividends is determined by the Meeting of Shareholders or, failing that, by the Executive Board. However, payment must
be made within a maximum of nine months after the end of the financial year, unless such period is extended by court decision.

Shareholders may not be required to reimburse any amount of dividends unless the distribution of dividends was in violation of law.

Claims for dividends made more than five years after they have been made available for payment shall time-barred.

II.       The Meeting of Shareholders convened to approve the financial statements for the financial year may grant shareholders the option of dividends or interim
dividends being paid in cash or in shares issued by Company, in whole or in part, in accordance with the conditions set out or authorised by law.

TITLE VIII
SHAREHOLDERS’ EQUITY FALLING BELOW ONE-HALF OF THE SHARE CAPITAL

ARTICLE 42 – Early Winding Up

If the Company's shareholders' equity falls below one-half of the share capital as a result of losses recorded in the financial statements, the Executive Board must
convene an Extraordinary Meeting of Shareholders within four months of the approval of the financial statements which recorded such loss to decide whether to
wind up the Company.

If it is not decided to wind up the Company, the share capital must be reduced by an amount equal to the recorded losses, within a period determined by law, if
shareholders’ equity has not reached at least one-half the amount of the share capital again within such period.

In either case, the decision of the Meeting of Shareholders shall be published according to regulatory conditions.

The reduction of share capital to an amount below the statutory minimum can only be decided subject to the condition precedent of a share capital increase to at
least the statutory minimum.

If the provisions of one or more of the foregoing paragraphs are not complied with, any interested party may apply to the courts for the Company to be wound up.
This rule also applies if the shareholders are unable to deliberate validly.

However, the court may not wind up the Company if on the day of issue of a judgment on the substance of the matter the situation has been rectified.

TITLE IX
WINDING-UP – LIQUIDATION

ARTICLE 43 – Winding Up

The  Company  shall  be  wound  up  on  expiry  of  the  term  determined  in  the  Articles  of  association,  unless  this  is  extended,  or  pursuant  to  a  decision  of  an
Extraordinary Meeting of Shareholders.

The Company may also be wound up at the request of any interested party, where the number of shareholders has dropped to under seven for more than one year.
In such case, the court may grant the Company a maximum of six months in which to rectify the situation. It cannot wind up the Company if on the day it issued
judgment on the substance of the matter, the situation has been rectified.

The Company shall be in liquidation as from the date on which it is wound up, for any reason whatsoever.

Winding  up  will  cause  the  terms  of  office  of  members  of  the  Executive  Board  to  terminate.  The  Supervisory  Board  and  Statutory  Auditors  shall  continue  to
operate.

Meeting of Shareholders shall retain the same powers as during the life of the company.

The  Meeting  of  Shareholders  which  decides  to  wind  up  the  company  shall  determine  the  procedure  for  liquidation  and  appoint  one  or  more  liquidators  and
determine their powers. The liquidator(s) shall exercise their duties in accordance with the law in force.

The  Company  shall  continue  to  have  legal  personality  for  the  purposes  of  and  until  the  completion  of  its  liquidation.  However,  its  corporate  name  should  be
followed  by  the  words  "Company  in  liquidation"  as  well  as  the  name(s)  of  the  liquidator(s)  on  any  instruments  or  documents  issued  by  the  Company  to  third
parties.

29

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
TRANSLATION FOR INFORMATION PURPOSES

Shares remain negotiable until the completion of liquidation.

After liabilities have been cleared, the net proceeds of liquidation are applied to the full repayment of paid up non-depreciated shares.

Any surplus shall be distributed among the shareholders in proportion to the number of shares held by each of them.

TITLE X
DISPUTES

ARTCLE 44 - Disputes

Any dispute which may arise during the life or liquidation of the Company, either between shareholders and the Company or between the shareholders themselves,
concerning corporate matters, shall be resolved in accordance with the law and submitted to the jurisdiction of the competent courts at the registered office.

To this effect, in the case of a dispute, any shareholder is bound to designate an address for service of process within the area of jurisdiction of the court of the
Company's registered office, any writs or notifications shall be validly issued to that address.

If an address for service of process is not designated, writs or notifications shall be validly issued to the Public Prosecutor of the Court of First Instance in the area
of the registered office.
