PART I 

Item 1.        Business. 

General Overview

(Dollar amounts in thousands, except per-share amounts and as otherwise noted)

Avadel  Pharmaceuticals  plc  (Nasdaq:  AVDL)  (“Avadel,”  the  “Company,”  “we,”  “our,”  or  “us”)  is  an  emerging  biopharmaceutical  company.  Our  lead
product candidate, FT218, is an investigational once-nightly formulation of sodium oxybate for the treatment of excessive daytime sleepiness (“EDS”), and
cataplexy in narcolepsy patients. FT218, which uses our Micropump drug-delivery technology, is in a Phase 3 clinical trial for the treatment of narcolepsy
patients suffering from EDS and cataplexy. In addition, we have three approved commercial products developed under our “unapproved marketed drug,” or
UMD, program, Akovaz, Bloxiverz and Vazculep, and a fourth approved product, Nouress, which are sterile injectable drugs used in the hospital setting.

We are primarily focused on the development and potential U.S. Food and Drug Administration (“FDA”) approval of FT218. In addition, we continue to
market  and  distribute  our  current  approved  hospital  products  portfolio  and,  pending  resolution  of  the  existing  patent  infringement  claim  (as  described
below), we plan to commercialize Nouress. Outside of our product candidate and our existing commercial products, we continue to evaluate opportunities
to expand our product portfolio.

FT218 (Micropump sodium oxybate)

FT218 is a once-nightly formulation of sodium oxybate that uses our Micropump controlled release drug-delivery technology for the treatment of EDS and
cataplexy in patients suffering from narcolepsy. Sodium oxybate is the sodium salt of gamma hydroxybutyrate, an endogenous compound and metabolite of
the  neurotransmitter  gamma-aminobutyric  acid.  Sodium  oxybate  is  approved  in  Europe  and  the  United  States  (“U.S.”)  as  a  twice-nightly  formulation
indicated for the treatment of EDS and cataplexy in patients with narcolepsy.

In December 2019, we completed patient enrollment of our Phase 3 REST-ON clinical trial of FT218 to assess the safety and efficacy of a once-nightly
formulation of FT218 for the treatment of EDS and cataplexy in patients suffering from narcolepsy. The REST-ON trial is a randomized, double-blind,
placebo-controlled study that has enrolled 212 patients and is being conducted in clinical sites in the U.S., Canada, Western Europe and Australia. Top line
data from the REST-ON trial is currently expected in the second quarter of 2020.

In January 2018, the FDA granted FT218 Orphan Drug Designation, which makes the drug eligible for certain development and commercial incentives,
including a potential U.S. market exclusivity for up to seven years. Additionally, in April 2019, our first FT218 patent was issued, providing intellectual
property protection into 2037. There are additional patent applications currently in development and/or pending at the U.S. Patent and Trademark Office
(“USPTO”), as well as foreign patent offices.

We believe FT218 has the potential to demonstrate improved dosing compliance, safety and patient satisfaction over the current standard of care for EDS
and cataplexy in patients with narcolepsy, which is a twice-nightly sodium oxybate formulation. If approved, we believe FT218 has the potential to take a
significant  share  of  the  sodium  oxybate  market.  The  current  market  size  for  the  twice-nightly  administration  of  sodium  oxybate  is  estimated  at  an
annualized revenue run rate of $1.7 billion.

Micropump Drug-Delivery Technology

Our Micropump drug-delivery technology allows for the delayed delivery of small molecule drugs taken orally, which has the potential to improve dosing
compliance, reduce toxicity and improve patient compliance. Beyond FT218, we believe there could be other product development opportunities for our
Micropump  drug  delivery  technology,  representing  either  “life  cycle”  opportunities,  whereby  additional  intellectual  property  can  be  added  to  a
pharmaceutical  product  to  extend  the  commercial  viability  of  a  currently  marketed  product,  or  innovative  formulation  opportunities  for  new  chemical
entities.

Unapproved Marketed Drugs Program

The  FDA  allows  certain  unapproved  prescription  drugs  to  be  marketed  if  (i)  they  are  relied  on  by  health  care  professionals  to  treat  serious  medical
conditions, and (ii) there is no FDA-approved drug to treat such condition or insufficient supply of FDA-approved drugs. In most cases, these prescription
drugs pre-date the establishment of the FDA. Although these products are typically not protected by patents or similar intellectual property, FDA guidance
states that, if it approves an NDA for any such products via a 505(b)(2) process, the FDA is more likely to seek enforcement action, such as seizure or
injunction, against remaining unapproved drugs of the same type, potentially after a grace period provided by the FDA.

Existing Commercial Products

To date, we have received FDA approvals for three previously unapproved prescription drugs:

Bloxiverz (neostigmine methylsulfate injection) - Bloxiverz was approved by the FDA in May 2013 and was launched in July 2013. Bloxiverz
is  a  drug  used  intravenously  in  the  operating  room  to  reverse  the  effects  of  non-depolarizing  neuromuscular  blocking  agents  after  surgery.
Bloxiverz was the first FDA-approved version of neostigmine methylsulfate. Today, neostigmine is one of the two most frequently used products
for the reversal of the effects of other agents used for neuromuscular blocks. There are approximately 2,500 vials of neostigmine sold annually in
the U.S.

Vazculep  (phenylephrine  hydrochloride  injection)  -  Vazculep  was  approved  by  the  FDA  in  June  2014  and  was  launched  in  October  2014.
Vazculep is indicated for the treatment of clinically important hypotension occurring in the setting of anesthesia. There are approximately 7,100
vials of Vazculep sold annually in the U.S.

Akovaz (ephedrine sulfate injection). Akovaz, was approved by the FDA in April 2016 and was launched in August 2016. Akovaz was the first
FDA approved formulation of ephedrine sulfate, an alpha- and beta- adrenergic agonist and a norepinephrine-releasing agent that is indicated for
the  treatment  of  clinically  important  hypotension  occurring  in  the  setting  of  anesthesia.  There  are  approximately  7,500  vials  of  Akovaz  sold
annually in the U.S.

•

•

Nouress

In December 2019, we received FDA approval for Nouress (cysteine hydrochloride injection), a sterile injectable product for use in the hospital setting, and
currently have two patents covering that product. Several additional patent applications for Nouress are pending with the USPTO. In light of the recently
filed patent suit by Exela Pharma Sciences, LLC, (“Exela”) we are currently evaluating the timing and process for a commercial launch of Nouress in the
U.S. See Note 16: Contingent Liabilities and Commitments in Part II of this Form 10-K for a discussion on the filed patent suit by Exela.

We  use  the  revenue  from  our  UMD  products  to  fund  the  research  and  development  of  FT218.  In  addition,  we  believe  evaluating  opportunities  to
commercialize other unapproved drugs in markets with a limited number of competitors may provide us with near-term revenue growth and potentially
provide cash flows that can also be used to fund research and development initiatives for the development of FT218 and other potential product candidates.

Recent Developments

Shelf Registration Statement on Form S-3

In February 2020, we filed with the SEC a new shelf registration statement on Form S-3 (the 2020 Shelf Registration Statement) (File No. 333-236258)
that allows issuance and sale by us, from time to time, of:

(a) up to $250,000 in aggregate of ordinary shares, nominal value US$0.01 per share (the “Ordinary Shares”), each of which may be represented by
ADSs, preferred shares, nominal value US$0.01 per share (the “Preferred Shares”), debt securities (the “Debt Securities”), warrants to purchase
Ordinary Shares, ADSs, Preferred Shares and/or Debt Securities (the “Warrants”), and/or units consisting of Ordinary Shares, ADSs, Preferred
Shares, one or more Debt Securities or Warrants in one or more series, in any combination, pursuant to the terms of the 2020 Shelf Registration
Statement, the base prospectus contained in the 2020 Shelf Registration Statement (the “Base Prospectus”), and any amendments or supplements
thereto (together, the “Securities”); including

(b) up to $50,000 of ADSs that may be issued and sold from time to time pursuant to the terms of an Open Market Sale AgreementSM (“the Sales
Agreement”),  entered  into  with  Jefferies  LLC  on  February  4,  2020  (the  “Sales  Agreement”),  the  2020  Shelf  Registration  Statement,  the  Base
Prospectus and the terms of the sales agreement prospectus contained in the 2020 Shelf Registration Statement.

Securities Purchase Agreement

On  February  21,  2020,  we  announced  that  we  have  entered  into  a  definitive  agreement  for  the  sale  of  our  ADSs  and  Series  A  Non-Voting  Convertible
Preferred Shares (“Series A Preferred”) in a private placement to a group of institutional accredited investors. The private placement has resulted in gross
proceeds of approximately $65,000 before deducting placement agent and other offering expenses, and resulting in net proceeds of approximately $61,000.

Pursuant to the terms of the private placement, we issued 8,680 ADSs and 488 shares of Series A Preferred at a price of $7.09 per share, priced at-the-
market under Nasdaq rules. Each share of non-voting Series A Preferred is convertible into one ADS, provided that conversion will be prohibited if, as a
result,  the  holder  and  its  affiliates  would  own  more  than  9.99%  of  the  total  number  of  Avadel  ADSs  outstanding.  The  closing  of  the  private  placement
occurred on February 25, 2020. Proceeds from the private placement will be used to fund continued clinical and program development of FT218, including
an open-label extension study for REST-ON, a switch study to evaluate patients switching from twice-nightly sodium oxybate to once-nightly FT218, as
well as for general corporate purposes.

Competition and Market Opportunities 

Competition 

Competition  in  the  pharmaceutical  and  biotechnology  industry  is  intense  and  is  expected  to  increase.  We  compete  with  academic  laboratories,  research
institutions, universities, joint ventures, and other pharmaceutical and biotechnology companies, including other companies developing brand or generic
specialty pharmaceutical products or drug delivery platforms. Some of these competitors may also be our business partners. There can be no assurance that
our competitors will not obtain patent protection or other intellectual property rights that would make it difficult or impossible for us to compete with their
products.  Furthermore,  major  technological  changes  can  happen  quickly  in  the  pharmaceutical  and  biotechnology  industries.  Such  rapid  technological
change,  or  the  development  by  our  competitors  of  technologically  improved  or  differentiated  products,  could  render  our  products,  including  our  drug
delivery technologies, obsolete or noncompetitive.

The pharmaceutical industry has dramatically changed in recent years, largely as a function of the growing importance of generic drugs. The growth of
generics (typically small molecules) and of large molecules (biosimilars) has been accelerated by the demand for less expensive pharmaceutical products.
As a result, the pricing power of pharmaceutical companies will be more tightly controlled in the future.

In addition, the overall landscape of the Pharma/Biotech industry has changed, and consolidation has reduced our pool of potential partners and acquisition
opportunities within the biopharmaceutical space.

We complete with a number of companies based upon our current marketed products and those in development. Examples of companies with whom Avadel
or any of our future partners would compete, given our current products and pipeline, include Jazz Pharmaceuticals, Fresenius Kabi, Par Pharmaceuticals,
Hikma Pharmaceuticals and Ferring.

 Potential competition for FT218

If FT218 receives FDA approval, it will compete with the current approved twice-nightly sodium oxybate formulation, as well as a number of daytime
stimulants including lisdexamfetamine, modafinil, armodafinil, solriamfetol and pitolisant, which are widely prescribed, or prescribed concomitantly with
sodium oxybate. Sodium oxybate is currently the only product approved for both EDS and cataplexy. In addition, we anticipate that our FT218 product may
face  competition  from  manufacturers  of  generic  twice-nightly  sodium  oxybate  formulations,  who  have  reached  settlement  agreements  with  the  current
marketer  for  entry  by  2023.  In  addition,  there  are  other  products  in  development  that  may  be  approved  in  the  future  that  could  have  an  impact  on  the
sodium oxybate market prior to FT218’s potential FDA approval, including low or no sodium versions of sodium oxybate and reboxetine.

Market Opportunities 

Because  the  pharmaceutical  industry  is  highly  competitive,  participants  seek  ways  to  increase  profitability  by  reducing  competition  through  patent
protection. Avadel, combining its existing proprietary drug delivery technologies with the established commercial capability of our unapproved to approved
product strategy has evolved into a biopharmaceutical company focusing on re-formulations and requiring shorter product development cycles by using an
abbreviated NDA mechanism (505(b)(2)).

In particular, in today’s environment, a drug has to demonstrate significant therapeutic improvements over the current standard of care in order to obtain
third party payer coverage. Alternatively, changes in the delivery of a drug must create a demonstrable reduction in costs. Dosing convenience, by itself, is
no  longer  sufficient  to  gain  reimbursement  acceptance.  Biopharmaceutical  companies  must  now  demonstrate,  through  costly  Phase  3  trials,  therapeutic
efficacy of their new formulations. The FDA has encouraged drug companies developing enhanced formulations to use an abbreviated regulatory pathway:
the 505(b)(2) NDA. Many biopharmaceutical companies today are using this approach or the supplemental NDA pathway (“sNDA”). An NDA or sNDA is
necessary to market an already approved drug for a new indication, or in a different dosage form or formulation. However, the sNDA approach requires
cross-referencing the originator’s drug dossier, and eventually an alliance with the originator for commercialization.

Avadel’s Drug Delivery Technologies 

We  own  drug  delivery  technologies  that  address  key  formulation  challenges,  potentially  allowing  the  development  of  differentiated  drug  products  for
administration in various forms (e.g., capsules, tablets, sachets or liquid suspensions for oral use; or injectables for subcutaneous administration) that could
be applied to a broad range of drugs (novel, already-marketed, or off-patent).

A brief discussion of each of our drug delivery technologies is set forth below.

• Micropump® Technology. Our Micropump allows for the development of modified and/or controlled release solid, oral dosage formulations of
drugs.  Micropump-carvedilol  and  Micropump-aspirin  formulations  have  been  approved  in  the  U.S.  Further,  Micropump  technology  is  being
employed in our investigational FT218 product.

•

LiquiTime®. Our LiquiTime technology allows for development of modified/controlled release oral products in a liquid suspension formulation,
which may make such formulations particularly well suited for children and/or patients having issues swallowing tablets or capsules. Although we
own this technology, we are currently not pursuing any commercial pharmaceutical drug development opportunities using it.

• Medusa™.  Our  Medusa  technology  allows  for  the  development  of  extended-/modified-release  injectable  dosage  formulations  of  drugs  (e.g.,
peptides,  polypeptides,  proteins,  and  small  molecules).  Although  we  own  this  technology,  we  are  currently  not  pursuing  any  commercial
pharmaceutical drug development opportunities using it.

Proprietary Intellectual Property 

Parts of our product pipeline and strategic alliances utilize our drug delivery platforms and related products of which certain features are the subject of
patents or patent applications. As a matter of policy, we seek patent protection of our inventions and also rely upon trade secrets, know-how, continuing
technological innovations and licensing opportunities to maintain and develop competitive positions.

FT218  Patents.  We  were  awarded  our  first  FT218-related  U.S.  patent  on  April  30,  2019,  which  is  directed  to  modified  release  formulations  of
gamma-hydroxybutyrate (“GHB”), and which expires in 2037. We have a number of additional, FT218-related patent applications pending at the
USPTO as well as at non-U.S. patent offices.

Nouress Patents. We have two issued U.S. patents directed to cysteine solutions and methods of using cysteine solutions, both of which are listed
in FDA’s Orange Book for Nouress, and both of which expire in 2039. Further, we have several Nouress-related patent applications pending at the
USPTO.

Drug Delivery Technology Patents. Our drug delivery technologies are the subject of certain patents, including: (i) for Micropump, patents relating
to coating technologies that provide for delayed and sustained release of an active ingredient and that tend to allow for absorption in the upper part
of  the  intestinal  tract  (expiring  in  2025  in  the  U.S.  and  2022  in  non-U.S.  jurisdictions);  (ii)  for  LiquiTime,  patents  relating  to  film-coated
microcapsules  and  a  method  comprising  orally  administering  such  microcapsules  to  a  patient  (expiring  in  2023);  and  (iii)  for  Medusa,  patents
relating  to  an  aqueous  colloidal  suspension  of  low  viscosity  based  on  submicronic  particles  of  water-soluble  biodegradable  polymer  PO
(polyolefin) carrying hydrophobic groups (expiring in 2023).

The  patent  positions  of  biopharmaceutical  companies  like  us  are  generally  uncertain  and  involve  complex  legal,  scientific  and  factual  questions.  In
addition, the coverage claimed in a patent application can be significantly reduced before the patent is issued, and patent scope can be reinterpreted by the
courts  after  issuance.  Moreover,  many  jurisdictions  permit  third  parties  to  challenge  issued  patents  in  administrative  proceedings,  which  may  result  in
further narrowing or even cancellation of patent claims. We cannot predict whether the patent applications we are currently pursuing will issue as patents in
any particular jurisdiction or whether the claims of any of our licensed or owned patents will provide sufficient protection from competitors. Any of our
licensed  or  owned  patents  may  be  challenged,  circumvented,  or  invalidated  by  third  parties.  For  more  information,  please  see  the  information  set  forth
under the caption “– Risks Related to Our Intellectual Property – If we cannot adequately protect our intellectual property and proprietary information, we
may be unable to sustain a competitive advantage” in the “Risk Factors” included in Part I, Item 1A of this Annual Report on Form 10-K.

Supplies and Manufacturing 

We attempt to maintain multiple suppliers in order to mitigate the risk of shortfall and inability to supply market demand. Nevertheless, for most of our
products, we rely on a limited number of suppliers, and in certain cases only one supplier, for sourcing active pharmaceutical ingredients (“APIs”).

The  manufacture  of  our  sterile  hospital  injectable  products  marketed  by  Avadel  in  the  U.S.  is  outsourced  to  current  good  manufacturing  practices
(“cGMP”) -compliant and FDA-audited contract manufacturing organizations (“CMOs”) pursuant to supply agreements. We will continue to outsource to
third-party CMOs, and have no present plans to acquire manufacturing facilities. We believe this outsourcing policy is beneficial to us for products to be
marketed in the U.S.

Government Regulation 

The design, testing, manufacturing and marketing of certain new or substantially modified drugs, biological products or medical devices must be approved,
cleared or certified by regulatory agencies, regulatory authorities and notified bodies under applicable laws and regulations, the requirements of which may
vary  from  country  to  country.  This  regulatory  process  is  lengthy,  expensive  and  uncertain.  In  the  U.S.,  the  FDA  regulates  such  products  under  various
federal statutes, including the Federal Food, Drug, and Cosmetic Act (“FDCA”) and the Public Health Service Act.

New Drug Product Development and Approval Process

Regulation by governmental authorities in the U.S. and other countries has a significant impact on the development, manufacture, and marketing of drug
products and on ongoing research and product development activities. The products of Avadel’s pharmaceutical partners as well as its own products require
regulatory  approval  by  governmental  agencies  and  regulatory  authorities  prior  to  commercialization.  In  particular,  these  products  are  subject  to
manufacturing  according  to  stringent  requirements  known  as  cGMP  which  are  promulgated  by  the  FDA  in  the  U.S.  and  by  other  authorities  in  other
jurisdictions,  and  rigorous,  pre-clinical  and  clinical  testing  and  other  pre-market  approval  requirements  by  the  FDA,  the  European  Commission  and
regulatory authorities in other countries. In the U.S. and the European Union, various statutes and regulations also govern or influence the manufacturing,
safety, labeling, storage, record keeping and marketing of pharmaceutical products. The lengthy process of seeking these approvals, and the subsequent
compliance with applicable statutes and regulations, require the expenditure of substantial resources.

Regulatory approval, when and if obtained, may be limited in scope. In particular, regulatory approvals may restrict the marketing of a product to specific
uses. Approved drugs, as well as their manufacturers, are subject to ongoing review (including requirements and restrictions related to record keeping and
reporting, FDA, European Commission and EU Member States competent authorities’ approval of certain changes in manufacturing processes or product
labeling, product promotion and advertising, and

-9-

 
 
 
 
 
pharmacovigilance, which includes monitoring and reporting adverse reactions, maintaining safety measures, and conducting dossier reviews for marketing
authorization renewal). Discovery of previously unknown problems with these products may result in restrictions on their manufacture, sale or use, or in
their withdrawal from the market. Failure to comply with regulatory requirements may result in criminal prosecution, civil penalties, recall or seizure of
products, total or partial suspension of production or injunction, as well as other actions affecting Avadel’s potential products and commercial prospects or
the potential products and commercial prospects of Avadel’s pharmaceutical partners who may utilize Avadel’s technologies. Any failure by Avadel or our
pharmaceutical  partners  to  comply  with  current  or  new  and  changing  regulatory  obligations,  and  any  failure  to  obtain  and  maintain,  or  any  delay  in
obtaining, regulatory approvals, could materially adversely affect our business.

The process for new drug product development and approval has many steps, including:

Chemical  and  Formulation  Development.  Pharmaceutical  formulation  taking  into  account  the  chemistry  and  physical  characteristics  of  the  drug  or
biological substance, is the beginning of a new product. If initial laboratory experiments reveal that the concept for a new drug product looks promising,
then a variety of further development steps and tests complying with internationally recognized guidance documents will have to be continued, in order to
provide for a product ready for testing in animals and, after sufficient animal test results, also in humans.

Concurrent  with  pre-clinical  studies  and  clinical  trials,  companies  must  continue  to  develop  information  about  the  properties  of  the  drug  product  and
finalize a process for manufacturing the product in accordance with cGMP. The manufacturing process must be capable of consistently producing quality
batches  of  the  product,  and  the  manufacturer  must  develop  and  validate  methods  for  testing  the  quality,  purity  and  potency  of  the  final  products.
Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the product does not undergo
unacceptable deterioration over its shelf-life.

Pre-Clinical  Testing.  Once  a  drug  candidate  is  identified  for  development,  the  candidate  enters  the  pre-clinical  testing  stage.  This  includes  laboratory
evaluation  of  product  chemistry  and  formulation,  as  well  as  animal  studies  of  pharmacology  (mechanism  of  action,  pharmacokinetics)  and  toxicology
which may have to be conducted over lengthy periods of time, to assess the potential safety and efficacy of the product as formulated. Pre-clinical tests
must be conducted in compliance with good laboratory practice regulations, the Animal Welfare Act and its regulations in the U.S. and the Clinical Trials
Directive  and  related  national  laws  and  guidelines  in  the  EU  Member  States.  Violations  of  these  laws  and  regulations  can,  in  some  cases,  lead  to
invalidation of the studies, then requiring such studies to be replicated. In some cases, long-term pre-clinical studies are conducted while clinical studies are
ongoing.

Investigational New Drug Application.

U.S.  The  entire  body  of  chemical  or  biochemical,  pharmaceutical  and  pre-clinical  development  work  necessary  to  administer  investigational  drugs  to
human volunteers or patients is summarized in an Investigational New Drug (“IND”) application to the FDA. The IND becomes effective, if not rejected by
the FDA within thirty (30) days after filing. There is no assurance that the submission of an IND will eventually allow a company to commence clinical
trials. All clinical trials must be conducted under the supervision of a qualified investigator in accordance with good clinical practice regulations to ensure
the  quality  and  integrity  of  clinical  trial  results  and  data.  These  regulations  include  the  requirement  that,  with  limited  exceptions,  all  subjects  provide
informed consent. In addition, an institutional review board (“IRB”), composed primarily of physicians and other qualified experts at the hospital or clinic
where the proposed studies will be conducted, must review and approve each human study. The IRB also continues to monitor the study and must be kept
aware of the study’s progress, particularly as to adverse events and changes in the research. Progress reports detailing the results of the clinical trials must
be submitted at least annually to the FDA and more frequently if adverse events occur. Failure to adhere to good clinical practices and the protocols, and
failure to obtain IRB approval and informed consent, may result in FDA rejection of clinical trial results and data, and may delay or prevent the FDA from
approving the drug for commercial use.

European  Union.  The  European  equivalent  to  the  IND  is  the  Investigational  Medicinal  Product  Dossier  (“IMPD”)  which  likewise  must  contain
pharmaceutical, pre-clinical and, if existing, previous clinical information on the drug substance and product. An overall risk-benefit assessment critically
analyzing the non-clinical and clinical data in relation to the potential risks and benefits of the proposed trial must also be included. The intended clinical
trial must be submitted for authorization by the regulatory authority(ies) of each EU Member States in which the trial is intended to be conducted prior to
its commencement. The trial must be conducted in accordance with the protocol as approved by an Ethics Committee(s) in each EU Member State (EU
equivalent to IRBs). Before submitting an application to the competent authority, the sponsor must register the trial in the EudraCT database where in the
U.S. it will be provided with a unique EudraCT number.

Clinical  Trials.  Typically,  clinical  testing  involves  the  administration  of  the  drug  product  first  to  healthy  human  volunteers  and  then  to  patients  with
conditions needing treatment under the supervision of a qualified principal investigator, usually a physician,

-10-

 
 
 
 
 
pursuant  to  a  ‘protocol’  or  clinical  plan  reviewed  by  the  FDA  and  the  competent  authorities  of  the  EU  Member  States  along  with  the  IRB  or  Ethics
Committee (via the IND or IMPD submission). The protocol details matter such as a description of the condition to be treated, the objectives of the study, a
description of the patient population eligible for the study, and the parameters to be used to monitor safety and efficacy.

Clinical trials are time-consuming and costly, and typically are conducted in three sequential phases, which sometimes may overlap. Phase I trials consist of
testing the product in a small number of patients or normal volunteers, primarily for safety, in one or more dosages, as well as characterization of a drug’s
pharmacokinetic and/or pharmacodynamic profile. In Phase 2, in addition to safety, the product is studied in a patient population to evaluate the product’s
efficacy for the specific, targeted indications and to determine dosage tolerance and optimal dosage. Phase 3 trials typically involve additional testing for
safety and clinical efficacy in an expanded patient population at geographically dispersed sites. With limited exceptions, all patients involved in a clinical
trial must provide informed consent prior to their participation. Meeting clinical endpoints in early stage clinical trials does not assure success in later stage
clinical trials. Phase 1, 2, and 3 testing may not be completed successfully within any specified time period, if at all.

The FDA and the competent authorities of EU Member States monitor the progress of each clinical trial phase conducted under an IND or IMPD and may,
at their discretion, reevaluate, alter, suspend or terminate clinical trials at any point in this process for various reasons, including a finding that patients are
being exposed to an unacceptable health risk or a determination that it is unethical to continue the study. The FDA, the European Commission and the
competent authorities of EU Member States can also request that additional clinical trials be conducted as a condition to product approval. The IRB, the
Ethics Committee, and sponsor also may order the temporary or permanent discontinuance of a clinical trial at any time for a variety of reasons, particularly
if  safety  concerns  arise.  Such  holds  can  cause  substantial  delay  and,  in  some  cases,  may  require  abandonment  of  product  development.  These  clinical
studies  must  be  conducted  in  conformance  with  the  FDA’s  bioresearch  monitoring  regulations,  the  EU  Clinical  Trials  Directive  and/or  internationally
recognized guidance such as the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (“ICH”).

New Drug Application. After the completion of the clinical trial phases of development, if the sponsor concludes substantial evidence exists that the drug
candidate is effective and that the drug is safe for its intended use, a new Drug Application (“NDA”) may be submitted to the FDA. The application must
contain all of the information on the drug candidate gathered to that date, including data from the pre-clinical and clinical trials, information pertaining to
the preparation of the drug, analytical methods, product formulation, details on the manufacture of finished products, proposed product packaging, labeling
and stability (shelf-life). NDAs are often over 100,000 pages in length. If FDA determines that a Risk Evaluation and Mitigation Strategy (“REMS”) is
necessary to ensure that the benefits of the drug outweigh the risks, a sponsor may be required to include as part of the application a proposed REMS,
including a package insert directed to patients, a plan for communication with healthcare providers, restrictions on a drug’s distribution, or a medication
guide to provide better information to consumers about the drug’s risks and benefits. Submission of an NDA does not assure FDA approval for marketing.

The  FDA  reviews  all  submitted  NDAs  before  it  accepts  them  for  filing  (the  U.S.  prerequisite  for  dossier  review).  The  FDA  may  refuse  to  file  the
application and request additional information rather than accepting an 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 review of the NDA to determine, among other things, whether a product is safe and effective for its intended use. As
part of this review, the FDA may refer the application to an appropriate advisory committee, typically a panel of clinicians, for review, evaluation and a
recommendation. There is a strong presumption for advisory committee review for any drug containing an active ingredient not previously approved. The
FDA is not bound by the recommendation of an advisory committee. Under the Prescription Drug User Fee Act (“PDUFA”), submission of an NDA with
clinical  data  requires  payment  of  a  fee.  In  return,  the  FDA  assigns  an  action  date  of  10  months  from  acceptance  of  the  application  to  return  of  a  first
‘complete  response,’  in  which  the  FDA  may  approve  the  product  or  request  additional  information  (PDUFA  also  provides  for  an  expedited,  six-month,
“priority review” process. There can be no assurance an application will be approved within the performance goal timeframe established under PDUFA, if
at all. If the FDA’s evaluation of the NDA is not favorable, the FDA usually will outline the deficiencies in the submission and request additional testing or
information. Notwithstanding the submission of any requested additional information, or even in lieu of asking for additional information, the FDA may
decide the marketing application does not satisfy the regulatory criteria for approval and issue a complete response letter, communicating the Agency’s
decision not to approve the application.

FDA approval of an NDA will be based, among other factors, on the Agency’s review of the pre-clinical and clinical data submitted, a risk/benefit analysis
of the product, and an evaluation of the manufacturing processes and facilities. Data obtained from clinical activities are not always conclusive and may be
susceptible to varying interpretations, which could delay, limit or prevent regulatory approval. The FDA has substantial discretion in the approval process
and  may  disagree  with  an  applicant’s  interpretation  of  the  data  submitted  in  its  NDA.  For  instance,  FDA  may  require  Avadel  to  provide  data  from
additional preclinical studies or clinical trials to support approval of certain development steps or the NDA itself. Among the conditions for NDA approval
is the requirement

-11-

 
 
 
 
that  each  prospective  manufacturer’s  quality  control  and  manufacturing  procedures  conform  to  cGMP  standards  and  requirements.  Manufacturing
establishments often are subject to Pre-Approval Inspections prior to NDA approval to assure compliance with cGMP manufacturing commitments made in
the relevant marketing application.

Patent Restoration and Exclusivity.  The  Drug  Price  Competition  and  Patent  Term  Restoration  Act  of  1984,  or  the  Hatch-Waxman  Act,  establishes  two
abbreviated approval pathways for drug products that are in some way follow-on versions of already approved products.

Generic Drugs. A generic version of an approved drug is approved by means of an Abbreviated New Drug Application (“ANDA”), by which the sponsor
demonstrates the proposed product is the same as the approved, brand-name drug, which is referred to as the “Reference Listed Drug” (“RLD”). Generally,
an ANDA must contain data and information showing the proposed generic product and RLD (1) have the same active ingredient, in the same strength and
dosage  form,  to  be  delivered  via  the  same  route  of  administration,  (2)  are  intended  for  the  same  uses,  and  (3)  are  bioequivalent.  This  is  instead  of
independently demonstrating the proposed product’s safety and effectiveness, which are inferred from the product being the same as the RLD, which the
FDA previously found to be safe and effective.

505(b)(2) NDAs. If a product is similar, but not identical, to an already approved product, it may be submitted for approval via an NDA under Section
505(b)(2) of the Act. Unlike an ANDA, this does not excuse the sponsor from demonstrating the proposed product’s safety and effectiveness. Rather, the
sponsor is permitted to rely to some degree on published scientific literature and the FDA’s finding that the RLD is safe and effective, and must submit its
own data of safety and effectiveness to an extent necessary because of the differences between the products.

RLD Patents. An NDA sponsor must advise the FDA about patents that claim the drug substance or drug product or a method of using the drug. When the
drug  is  approved,  those  patents  are  among  the  information  about  the  product  that  is  listed  in  the  FDA  publication,  Approved  Drug  Products  with
Therapeutic Equivalence Evaluations, which is referred to as the “Orange Book”. The sponsor of an ANDA or 505(b)(2) application seeking to rely on an
approved product as the RLD must make one of several certifications regarding each listed patent. A “Paragraph III” certification is the sponsor’s statement
that  it  will  wait  for  the  patent  to  expire  before  obtaining  approval  for  its  product.  A  “Paragraph  IV”  certification  is  a  challenge  to  the  patent;  it  is  an
assertion that the patent does not block approval of the later product, because the patent is invalid, unenforceable, and/or not infringed by the new product.

Once the FDA accepts for filing an ANDA or 505(b)(2) application containing a Paragraph IV certification, the applicant must within 20 days provide
notice to the RLD NDA holder and patent owner that the application with patent challenge has been submitted, and provide the factual and legal basis for
the applicant’s assertion that the patent is invalid, unenforceable, or not infringed. If the NDA holder or patent owner file suit against the ANDA or 505(b)
(2) applicant for patent infringement within 45 days of receiving the Paragraph IV notice, the FDA is prohibited from approving the ANDA or 505(b)(2)
application for a period of 30 months from the date of receipt of the notice. If the RLD has new chemical entity (“NCE”) exclusivity and the notice is given
and suit filed during the fifth year of exclusivity, the 30-month stay does not begin until five years after the RLD approval. The FDA may approve the
proposed product before the expiration of the 30-month stay i) if a court finds the patent invalid, unenforceable, or not infringed, ii) if the court shortens the
period because the parties have failed to cooperate in expediting the litigation, or iii) if the parties reach a settlement agreement and notify the FDA of
same.

As  an  alternative  to  Paragraph  IV  certification,  and  only  with  respect  to  method  of  use  patents,  an  applicant  can  ‘carve  around’  a  “Patent  Use  Code”
associated with a particular patent in the FDA’s Orange Book. A Patent Use Code is supposed to describe an indication/use of the RLD that is i) set forth in
the RLD label and ii) covered by the corresponding method of use patent. As such, in lieu of a Paragraph IV certification, an applicant can demonstrate to
the FDA that its proposed label does not include the method of use described by the RLD’s Patent Use Code for the corresponding method of use patent
and,  thus,  ‘carve  around’  that  Patent  Use  Code.  If  a  ‘carve  around’  is  successful,  the  notice  requirement  and  30-month  stay  on  FDA  approval  of  the
application described above with respect to a Paragraph IV certification for that particular method of use patent does not apply.

Regulatory Exclusivities. The Hatch-Waxman Act may provide periods of regulatory exclusivity for products that would serve as RLDs. If a product is a
“new chemical entity,” or NCE, - generally meaning that the active moiety has never before been approved in any drug - there may be a period of five years
from the product’s approval during which the FDA may not accept for filing any ANDA or 505(b)(2) application for a drug with the same active moiety.
An  ANDA  or  505(b)(2)  application  may  be  submitted  after  four  years,  however,  if  the  sponsor  makes  a  Paragraph  IV  certification  challenging  a  listed
patent.

An RLD that is not an NCE may qualify for a three-year period of exclusivity, if the NDA contains clinical data necessary for approval. In that instance, the
exclusivity period does not preclude filing or review of the ANDA or 505(b)(2) application; rather, the FDA is precluded from granting final approval to
the ANDA or 505(b)(2) application until three years after approval of the

-12-

 
 
 
 
 
 
RLD.  Additionally,  the  exclusivity  applies  only  to  the  conditions  of  approval  that  required  submission  of  the  clinical  data.  For  example,  if  an  NDA  is
submitted  for  an  RLD  that  is  not  an  NCE,  but  that  seeks  approval  for  a  new  indication,  and  clinical  data  were  required  to  demonstrate  the  safety  or
effectiveness of the RLD for that use, the FDA could not approve an ANDA or 505(b)(2) application for another product with that active moiety for that
use. For example, Coreg CRTM received three-year exclusivity for the clinical trials that demonstrated the safety and efficacy of the new, controlled-release
dosage form; that exclusivity, which has expired, blocked other controlled-release products.

For a brief discussion of potential marketing exclusivity that could be available under certain conditions with respect to Avadel’s product candidate FT218,
please see the information set forth under the caption “Risks Related to Regulatory and Legal Matters – If FT218 is approved by the FDA, we may not
obtain orphan drug marketing exclusivity” in the “Risk Factors” included in Part I, Item 1A of this Annual Report on Form 10-K.

Patent  Term  Restoration.  Under  the  Hatch-Waxman  Act,  a  portion  of  the  patent  term  lost  during  product  development  and  FDA  review  of  an  NDA  or
505(b)(2) application is restored if approval of the application is the first permitted commercial marketing of a drug containing the active ingredient. The
patent term restoration period is generally one-half the time between the effective date of the IND and the date of submission of the NDA, plus the time
between the date of submission of the NDA and the date of FDA approval of the product. The maximum period of restoration is five years, and the patent
cannot be extended to more than 14 years from the date of FDA approval of the product. Only one patent claiming each approved product is eligible for
restoration and the patent holder must apply for restoration within 60 days of approval. The USPTO, in consultation with the FDA, reviews and approves
the application for patent term restoration. In the event that Avadel applies for patent term extensions on patents covering Avadel’s products, the FDA and
the USPTO may not agree with Avadel’s assessment of whether such extensions are available, and may refuse to grant extensions to Avadel’s patents, or
may grant more limited extensions than Avadel requests. Moreover, Avadel may not receive an extension because of, for example, failing to apply within
applicable deadlines, failing to apply prior to expiration of relevant patents or otherwise failing to satisfy applicable requirements.

Regulation of Combination Drugs.  Medical  products  containing  a  combination  of  drugs,  biologic,  or  device  products  may  be  regulated  as  ‘combination
products’  in  the  U.S.  A  combination  product  generally  is  defined  as  a  product  comprising  components  from  two  or  more  regulatory  categories  (e.g.,
drug/device, device/biologic, drug/biologic). Each component of a combination product is subject to the requirements established by the FDA for that type
of component, whether a drug, biologic or device.

To determine which FDA center or centers will review a combination product submission, companies may submit a request for assignment to the FDA.
Those requests may be handled formally or informally. In some cases, jurisdiction may be determined informally based on FDA experience with similar
products. However, informal jurisdictional determinations are not binding on the FDA. Companies also may submit a formal Request for Designation to the
FDA Office of Combination Products. The Office of Combination Products will review the request and make its jurisdictional determination within 60 days
of receiving a Request for Designation.

In  order  to  facilitate  pre-market  review  of  combination  products,  the  FDA  designates  one  of  its  centers  to  have  primary  jurisdiction  for  the  pre-market
review and regulation of both components. The determination whether a product is a combination product or two separate products is made by the FDA on
a  case-by-case  basis.  It  is  possible  that  Avadel’s  delivery  platforms,  when  coupled  with  a  drug  or  medical  device  component,  could  be  considered  and
regulated by the FDA as a combination product.

If the primary mode of action is determined to be a drug, the product will be reviewed by the Center for Drug Evaluation and Research (“CDER”) either in
consultation with another center or independently. If the primary mode of action is determined to be a medical device, the product would be reviewed by
Center for Devices and Radiological Health (“CDRH”) either in consultation with another center, such as CDER, or independently. In addition, FDA could
determine that the product is a biologic and subject to the jurisdiction of the Center for Biologic Evaluation and Research (“CBER”), although it is also
possible that a biological product will be regulated by CDER.

Marketing Approval and Reporting Requirements. If the FDA approves an NDA, the product becomes available for physicians to prescribe. The FDA may
require  post-marketing  studies,  also  known  as  Phase  IV  studies,  as  a  condition  of  approval  to  develop  additional  information  regarding  the  safety  of  a
product. These studies may involve continued testing of a product and development of data, including clinical data, about the product’s effects in various
populations and any side effects associated with long-term use. After approval, the FDA may require post-marketing studies or clinical trials, as well as
periodic status reports, if new safety information develops. These post-marketing studies may include clinical trials to investigate known serious risks or
signals of serious risks or identify unexpected serious risks. Failure to conduct these studies in a timely manner may result in substantial civil fines and can
result in withdrawal of approval. Avadel has several Phase IV obligations with its current approvals.

-13-

 
 
 
 
 
 
 
In  addition,  the  FDA  may  require  distribution  to  patients  of  a  medication  guide  such  as  a  Risk  Evaluation  and  Mitigation  Strategies  (“REMS”)  for
prescription products that the agency determines pose a serious and significant health concern in order to provide information necessary to patients’ safe
and effective use of such products. We expect our FT218 product, if approved by the FDA will be subject to a REMS program.

In the European Union, the marketing authorization of a medicinal product may be made conditional on the conduct of Phase IV post-marketing studies.
Failure to conduct these studies in relation to centrally authorized products can lead to the imposition of substantial fines. Moreover, Phase IV studies are
often conducted by companies in order to obtain further information on product efficacy and positioning on the market in view of competitors and to assist
in application for pricing and reimbursement.

Other Post-Marketing Obligations. Any products manufactured and/or distributed pursuant to FDA approvals are subject to continuing regulation by the
FDA,  including  recordkeeping  requirements,  reporting  of  adverse  experiences  with  the  product,  submitting  other  periodic  reports,  drug  sampling  and
distribution  requirements,  notifying  the  FDA  and  gaining  its  approval  of  certain  manufacturing  or  labeling  changes,  complying  with  certain  electronic
records and signature requirements, submitting periodic reports to the FDA, maintaining and providing updated safety and efficacy information to the FDA,
and complying with FDA promotion and advertising requirements. For example, the FDA has required Avadel to conduct post-marketing clinical and non-
clinical studies for several of its products to be completed between 2016 and 2019.

Drug manufacturers and their subcontractors are required to register their establishments with the FDA and certain state agencies, and to list their products
with the FDA. The FDA periodically inspects manufacturing facilities in the U.S. and elsewhere in order to assure compliance with the applicable cGMP
regulations and other requirements. Facilities also are subject to inspections by other U.S. federal, foreign, state or local agencies. In complying with the
cGMP regulations, manufacturers must continue to expend time, money and effort in recordkeeping and quality control to assure that the product meets
applicable  specifications  and  other  post-marketing  requirements.  Failure  of  Avadel  or  its  licensees  to  comply  with  FDA’s  cGMP  regulations  or  other
requirements could have a significant adverse effect on Avadel’s business, financial condition and results of operations.

Also, newly discovered or developed safety or efficacy data may require changes to a product’s approved labeling, including the addition of new warnings
and  contraindications,  additional  pre-clinical  or  clinical  studies,  or  even  in  some  instances,  revocation  or  withdrawal  of  the  approval.  Violations  of
regulatory  requirements  at  any  stage,  including  after  approval,  may  result  in  various  adverse  consequences,  including  the  FDA’s  delay  in  approving  or
refusal  to  approve  a  product,  withdrawal  or  recall  of  an  approved  product  from  the  market,  other  voluntary  or  FDA-initiated  action  that  could  delay  or
restrict further marketing, and the imposition of civil fines and criminal penalties against the manufacturer and NDA holder. In addition, later discovery of
previously unknown problems may result in restrictions on the product, manufacturer or NDA holder, including withdrawal of the product from the market.
Furthermore, new government requirements may be established that could delay or prevent regulatory approval of Avadel’s products under development, or
affect the conditions under which approved products are marketed.

The Food and Drug Administration Amendments Act of 2007 (“FDAAA”) provides the FDA with expanded authority over drug products after approval.
This legislation enhances the FDA’s authority with respect to post-marketing safety surveillance, including, among other things, the authority to require
additional post-marketing studies or clinical trials, labeling changes as a result of safety findings, registering clinical trials, and making clinical trial results
publicly available.

In the European Union, stringent pharmacovigilance regulations oblige companies to appoint a suitably qualified and experienced Qualified Person resident
in the European Economic Area, to prepare and submit to the competent authorities adverse event reports within specific time lines, prepare Periodic Safety
Update Reports (“PSURs”) and provide other supplementary information, report to authorities at regular intervals and take adequate safety measures agreed
with regulatory agencies as necessary. Failure to undertake these obligations can lead to the imposition of substantial fines.

Other Regulation

Controlled  Substances  Act.  Narcotics  and  other  APIs,  such  as  sodium  oxybate  and  ephedrine  sulfate  are  “controlled  substances”  under  the  Controlled
Substances Act. The U.S. federal “Controlled Substances Act” (“CSA”), Title II of the Comprehensive Drug Abuse Prevention and Control Act of 1970,
regulates the manufacture and distribution of narcotics and other controlled substances, including stimulants, depressants and hallucinogens in the U.S. The
CSA  is  administered  by  the  “Drug  Enforcement  Administration”  (“DEA”),  a  division  of  the  U.S.  Department  of  Justice,  and  is  intended  to  prevent  the
abuse or diversion of controlled substances into illicit channels of commerce. Avadel has several products marketed under this Act and has at least one
product under development.

Any person or firm that manufactures, distributes, dispenses, imports, or exports any controlled substance (or proposes to do so) must register with the
DEA. The applicant must register for a specific business activity related to controlled substances, including

-14-

 
 
 
 
 
 
 
manufacturing  or  distributing,  and  may  engage  in  only  the  activity  or  activities  for  which  it  is  registered.  The  DEA  conducts  periodic  inspections  of
registered establishments that handle controlled substances and allots quotas of controlled drugs to manufacturers and marketers’ failure to comply with
relevant  DEA  regulations,  particularly  as  manifested  in  the  loss  or  diversion  of  controlled  substances,  can  result  in  regulatory  action  including  civil
penalties, refusal to renew necessary registrations, or proceedings to revoke those registrations. In certain circumstances, violations can lead to criminal
prosecution. In addition to these federal statutory and regulatory obligations, there may be state and local laws and regulations relevant to the handling of
controlled substances or listed chemicals.

cGMP. Current Good Manufacturing Practices rules apply to the manufacturing of drugs and medical devices. In addition to regulations enforced by the
FDA, Avadel is also subject to French, U.S. and other countries’ rules and regulations governing permissible laboratory activities, waste disposal, handling
of toxic, dangerous or radioactive materials and other matters. Avadel’s R&D involves the controlled use of hazardous materials, chemicals, viruses and
various radioactive compounds. Although Avadel believes that its safety procedures for handling and disposing of such materials comply with the standards
prescribed  by  French,  EU,  U.S.  and  other  foreign  rules  and  regulations,  the  risk  of  accidental  contamination  or  injury  from  these  materials  cannot  be
completely eliminated.

Health Care Fraud and Abuse. Avadel is subject to a number of federal and state laws pertaining to health care “fraud and abuse,” such as anti-kickback and
false claims laws. Under anti-kickback laws, it is illegal for a prescription drug manufacturer to solicit, offer, receive, or pay any remuneration in exchange
for, or to induce, the referral of business, including the purchase or prescription of a particular drug. Due to the breadth of the statutory provisions and the
absence  of  guidance  via  regulations  and  that  there  are  few  court  decisions  addressing  industry  practices,  it  is  possible  that  Avadel’s  practices  might  be
challenged under anti-kickback or similar laws. False claims laws prohibit anyone from knowingly and willingly presenting, or causing to be presented for
payment to third-party payors (such as the Medicare and Medicaid programs) claims for reimbursed drugs or services that are false or fraudulent, claims for
items  or  services  not  provided  as  claimed,  or  claims  for  medically  unnecessary  items  or  services.  Avadel’s  sales  and  marketing  activities  relating  to  its
products could be subject to scrutiny under these laws. Violations of fraud and abuse laws may be punishable by criminal and/or civil sanctions, including
fines  and  civil  monetary  penalties,  the  possibility  of  exclusion  from  federal  health  care  programs  (including  Medicare  and  Medicaid)  and  corporate
integrity agreements, which impose, among other things, rigorous operational and monitoring requirements on companies. In addition, similar sanctions
and penalties can be imposed upon executive officers and employees, including criminal sanctions against executive officers. As a result of the potential
penalties that can be imposed on companies and individuals if convicted, allegations of such violations often result in settlements even if the company or
individual being investigated admits no wrongdoing. Settlements often include significant civil sanctions, including fines and civil monetary penalties, and
corporate integrity agreements. If the U.S. government were to allege or convict Avadel or its executive officers of violating these laws, Avadel’s business
could be harmed. In addition, private individuals have the ability to bring similar actions. In addition to the reasons noted above, Avadel’s activities could
be subject to challenge due to the broad scope of these laws and the increasing attention being given to them by law enforcement authorities. There also are
an increasing number of U.S. federal and state laws that require manufacturers to make reports to states on pricing, marketing information, and payments
and other transfers of value to healthcare providers. Many of these laws contain ambiguities as to what is required to comply with the laws. Given the lack
of clarity in laws and their implementation, Avadel’s reporting actions could be subject to the penalty provisions of the pertinent authorities.

Healthcare  Privacy  and  Security  Laws.  Avadel  may  be  subject  to,  or  its  marketing  activities  may  be  limited  by  the  Health  Insurance  Portability  and
Accountability  Act  of  1996  (“HIPAA”),  as  amended  by  the  Health  Information  Technology  and  Clinical  Health  Act  and  their  respective  implementing
regulations, which established uniform standards for certain “covered entities” (healthcare providers, health plans and healthcare clearinghouses) governing
the  conduct  of  certain  electronic  healthcare  transactions  and  protecting  the  security  and  privacy  of  protected  health  information.  Among  other  things,
HIPAA’s privacy and security standards are directly applicable to “business associates” – independent contractors or agents of covered entities that create,
receive, maintain or transmit protected health information in connection with providing a service for or on behalf of a covered entity. In addition to possible
civil and criminal penalties for violations, state attorney generals are authorized to file civil actions for damages or injunctions in U.S. federal courts to
enforce HIPAA and seek attorney’s fees and costs associated with pursuing federal civil actions. In addition, state laws govern the privacy and security of
health information in certain circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating
compliance  efforts.  In  the  EU/EEA,  Directive  95/46/EEC  (as  amended)  or  its  successor  applies  to  identified  or  identifiable  personal  data  processed  by
automated means (e.g., a computer database of customers) and data contained in, or intended to be part of, non-automated filing systems (traditional paper
files) as well as transfer of such data to a country outside of the EU/EEA.

“Sunshine”  and  Marketing  Disclosure  Laws.  There  are  an  increasing  number  of  U.S.  federal  and  state  “sunshine”  laws  that  require  pharmaceutical
manufacturers  to  make  reports  to  states  on  pricing  and  marketing  information.  Several  U.S.  states  have  enacted  legislation  requiring  pharmaceutical
companies to, among other things, establish marketing compliance programs, file periodic reports with the state, and make periodic public disclosures on
sales and marketing activities, and prohibiting certain other sales

-15-

 
 
 
and marketing practices. In addition, a similar recently implemented federal requirement requires manufacturers, including pharmaceutical manufacturers,
to  track  and  report  to  the  federal  government  certain  payments  and  other  transfers  of  value  made  to  physicians  and  other  healthcare  professionals  and
teaching  hospitals  and  ownership  or  investment  interests  held  by  physicians  and  their  immediate  family  members.  The  U.S.  federal  government  began
disclosing the reported information on a publicly available website in 2014. These laws may adversely affect Avadel’s sales, marketing, and other activities
with respect to its medicines in the U.S. by imposing administrative and compliance burdens on us. If Avadel fails to track and report as required by these
laws or otherwise comply with these laws, it could be subject to the penalty provisions of the pertinent U.S. state and federal authorities.

Government  Price  Reporting.  For  those  marketed  medicines  which  are  covered  in  the  U.S.  by  the  Medicaid  programs,  Avadel  has  various  obligations,
including government price reporting and rebate requirements, which generally require medicines be offered at substantial rebates/discounts to Medicaid
and  certain  purchasers  (including  “covered  entities”  purchasing  under  the  340B  Drug  Discount  Program).  Avadel  is  also  required  to  discount  such
medicines to authorized users of the Federal Supply Schedule of the General Services Administration, under which additional laws and requirements apply.
These programs require submission of pricing data and calculation of discounts and rebates pursuant to complex statutory formulas, as well as the entry
into government procurement contracts governed by the Federal Acquisition Regulations, and the guidance governing such calculations is not always clear.
Compliance  with  such  requirements  can  require  significant  investment  in  personnel,  systems  and  resources,  but  failure  to  properly  calculate  Avadel’s
prices,  or  offer  required  discounts  or  rebates  could  subject  it  to  substantial  penalties.  One  component  of  the  rebate  and  discount  calculations  under  the
Medicaid and 340B programs, respectively, is the “additional rebate”, a complex calculation which is based, in part, on the rate at which a branded drug
price increases over time more than the rate of inflation (based on the CPI-U). This comparison is based on the baseline pricing data for the first full quarter
of sales associated with a branded drug’s NDA, and baseline data cannot generally be reset, even on transfer of the NDA to another manufacturer. This
“additional rebate” calculation can, in some cases where price increases have been relatively high versus the first quarter of sales of the NDA, result in
Medicaid rebates up to 100 percent of a drug’s “average manufacturer price” and 340B prices of one penny.

Healthcare Reimbursement

In  both  U.S.  and  non-U.S.  markets,  sales  of  Avadel’s  potential  products  as  well  as  products  of  pharmaceutical  and  biotechnology  companies  that
incorporate  Avadel’s  technology  into  their  products,  if  any,  will  depend  in  part  on  the  availability  of  reimbursement  by  third-party  payers,  such  as
government health administration authorities, private health insurers and other organizations. The U.S. market for pharmaceutical products is increasingly
being shaped by managed care organizations, pharmacy benefit managers, cooperative buying organizations and large drugstore chains. Third-party payers
are challenging the price and cost effectiveness of medical products and services. Uncertainty particularly exists as to the reimbursement status of newly
approved healthcare products. There can be no assurance reimbursement will be available to enable Avadel to maintain price levels sufficient to realize an
appropriate  return  on  our  product  development  investment.  Legislation  and  regulations  affecting  the  pricing  of  pharmaceuticals  may  change  before
Avadel’s proposed products are approved for marketing and any such changes could further limit reimbursement for medical products and services.

Employees

As of December 31, 2019, we had approximately 50 employees, all of which were full-time.  Except for employees at our French subsidiaries, none of our
other  employees  is  subject  to  a  union  or  other  collective  bargaining  agreement.    Additionally,  employees  at  our  French  subsidiaries  (approximately  19
employees) are represented by a works’ council in which employee representatives have the right to be consulted as to certain matters affecting our French
subsidiaries.  We believe that our relations with our employees are satisfactory.

Item 1A.    Risk Factors.

An investment in Avadel involves a high degree of risk. You should carefully consider the risks described below, as well as the other information included or
incorporated by reference in this Annual Report on Form 10-K, before making an investment decision. Avadel’s business, financial condition, results of
operations and cash flows could be materially adversely affected by any of these risks. The market or trading price of Avadel’s securities could decline due
to  any  of  these  risks.  In  addition,  please  read  “Cautionary  Disclosure  Regarding  Forward-Looking  Statements”  in  this  Annual  Report  on  Form  10-K,
where  we  describe  additional  uncertainties  associated  with  Avadel’s  business  and  with  the  forward-looking  statements  included  or  incorporated  by
reference in this Annual Report on Form 10-K. Please note that additional risks not presently known to us or that we currently deem immaterial may also
impair Avadel’s business and operations.

Risks Relating to Our 2019 Net Loss and 2019 Restructuring Plan

Our net loss and use of cash from operating activities may limit our ability to fully pursue our business strategy.

We reported a net loss of $33.2 million in 2019 and a loss from operating activities of $38.3 million. As a result, our cash and marketable securities as of
December 31, 2019 totaled $64.2 million. Our business strategy is to primarily focus on the development and potential FDA approval for FT218 which is
in a Phase 3 clinical trial for the treatment of narcolepsy patients suffering from EDS and cataplexy. In addition, we will continue to maximize the value of
our  current  approved  hospital  products  portfolio,  including  the  potential  commercialization  of  our  fourth  product,  Nouress  (cysteine  hydrochloride
injection).  The  successful  pursuit  of  all  components  of  our  strategy  will  require  substantial  financial  resources,  and  there  can  be  no  assurance  that  our
existing  cash  and  marketable  securities  assets  and  the  cash  generated  by  our  operations  will  be  adequate  for  these  purposes.  Failure  to  implement  any
component  of  our  strategy  may  prevent  us  from  achieving  profitability  in  the  future  or  may  otherwise  have  a  material  adverse  effect  on  our  financial
condition and results of operation.

Our restructuring plan announced in February 2019 may not be as effective as anticipated, and we may fail to fully realize the expected cost savings or
may experience unintended negative impacts from the restructuring.

In  February  2019,  we  announced  a  restructuring  plan  intended  to  achieve  future  cost  savings  through,  among  other  actions,  a  reduction  of  our  overall
workforce by approximately 50 percent. In conjunction with the restructuring plan, we also announced the voluntary Chapter 11 bankruptcy filing by our
subsidiary,  Avadel  Specialty  Pharmaceuticals,  LLC  (“Specialty  Pharma”),  which  was  responsible  solely  for  the  sales,  marketing  and  distribution  of  our
Noctiva product. We refer to the restructuring plan and the Chapter 11 bankruptcy of Specialty Pharma as the 2019 Restructuring. We implemented the
restructuring  plan  in  light  of  disappointing  results  from  the  commercial  launch  of  Noctiva,  and  in  order  to  focus  our  resources  on  other  product
development activities, in particular the ongoing Phase 3 clinical trial of FT218 for the treatment of excessive daytime sleepiness (“EDS”), and cataplexy in
narcolepsy patients. The 2019 Restructuring requires the devotion of management attention as well as significant resources, including pre-tax cash charges
which were approximately $12.0 million in 2019, and may pose significant risks. The 2019 Restructuring may not be as effective as we anticipated and
may not fully produce the expected cost savings or the effective re-focusing of our efforts toward completing the development of FT218. In addition, the
restructuring  plan  may  result  in  greater  implementation  costs  than  we  have  estimated  or  may  result  in  unintended  negative  consequences.  For  example,
because of the speed and magnitude of the workforce reduction that occurred during the 2019 restructuring, it may be difficult in the future to retain certain
remaining employees who are critical to our ability to successfully pursue our business plan.

If we need to take further restructuring actions, necessary third-party consents may not be granted.

Our management may determine we need to take further restructuring actions to achieve additional cost savings, to generate additional capital needed for
our business strategy, or for other purposes. Certain restructuring scenarios that management consider could require obtaining the consent of third parties,
such  as  holders  of  our  Exchangeable  Senior  Notes,  or  the  2023  Notes.  For  example,  the  voluntary  bankruptcy  filing  by  Specialty  Pharma  required  the
consent of holders of a majority in principal amount of our 2023 Notes in order to avoid a default under the Indenture governing such 2023 Notes. While
we  were  successful  in  obtaining  that  consent,  there  can  be  no  assurance  we  will  be  successful  in  obtaining  additional  consents  in  the  future  from  such
holders or from other third parties whose consents may be required. Failure to obtain these third-party consents would prevent us from taking additional
restructuring  actions,  which  could  have  a  material  adverse  effect  on  our  cash  flow,  financial  resources  and  ability  to  successfully  pursue  our  business
strategy.

The Chapter 11 bankruptcy filing by Specialty Pharma may have unexpected adverse results.

As part of the 2019 Restructuring, Avadel US Holdings Inc., Specialty Pharma’s immediate parent and our wholly-owned subsidiary, agreed to provide
debtor-in-possession financing to Specialty Pharma of up to $2.7 million. We could face challenges in having

-17-

the  liquidation  plan  for  Specialty  Pharma  approved  and  costs  from  the  restructuring  may  exceed  the  amount  of  financing  Avadel  US  Holdings  Inc.  has
committed to provide. Adverse or unexpected results from the bankruptcy proceeding could impair the success of the 2019 Restructuring.

A management-directed third-party evaluation of our FT218 development program could result in changes that increase the cost of the program and
further delay its completion.

We  recently  announced  completion  of  enrollment  in  the  clinical  trial  for  our  FT218  product  and  an  estimated  completion  date  for  that  clinical  trial.
Management, in conjunction with pharmaceutical industry consulting firms, continues its evaluation of the FT218 program. The results of this on-going
evaluation, in addition to the results of our FT218 development program, including our pivotal phase III REST ON study and all other components of an
NDA submission, could cause us to modify our development plan with respect to FT218 in ways that could materially increase the ultimate cost of such
development or further delay its completion, or could identify unknown risks or problems with the product. Any such cost increases, added delays, risks or
problems could have a material adverse effect on our financial condition and results of operation.

Risks Relating to Our Business and Industry

We derive a substantial majority of our revenues from a small number of products facing competitive pressures, and from a small number of customers,
and the loss of any one of these products or customers could reduce Avadel’s revenues significantly.

In 2019, we derived our $59.2 million in revenues from sales of our three hospital products, Bloxiverz, Vazculep and Akovaz. Product sales of these three
products  declined  in  the  aggregate  from  2018  to  2019  by  $38.3 million,  or  39.2%,  from  $97.5 million  to  $59.2  million.  Our  Noctiva  product  failed  to
achieve  anticipated  revenue  levels  despite  a  substantial  investment  of  resources  toward  its  commercialization,  and  these  disappointing  results  led  to  the
voluntary Chapter 11 bankruptcy filing by Specialty Pharma in February 2019. In addition, we depend on a small number of customers for the majority of
our revenues from our three hospital products. Three customers accounted for approximately 71% of total revenues from sales of these products in 2019.
These three customers comprise a significant portion of the distribution network for pharmaceutical products in the U.S.

Competition for our hospital products in 2019 caused significant downward pricing pressure and loss of market share by us resulting in lower aggregate
revenues  for  these  products.  Further  competition  in  the  future  could  cause  further  reductions  in  prices  and  market  share.  The  distribution  network  for
pharmaceutical  products  is  continuing  to  undergo  consolidation  marked  by  mergers  and  acquisitions  among  wholesale  distributors  and  retail  drug  store
chains. As a result, a small number of large wholesale distributors and large chain drug stores control a significant share of the market. We expect that
continuing consolidation in the industry may cause competitive pressures on pharmaceutical companies. The loss of any one of our three hospital products,
the termination of our relationship with any of our customers or our failure to broaden our customer base could cause our revenues to further decrease
significantly and result in further losses from our operations. Further, we may be unable to negotiate favorable business terms with customers that represent
a significant portion of our revenues, and any such inability could have a material adverse effect on our business, results of operations, financial condition
and prospects.

Further,  as  part  of  our  2013  debt  financing  transaction  with  Deerfield,  we  granted  Deerfield  a  security  interest  in  the  intellectual  property  and  product
registration rights of certain legacy products. If we default on the terms of the loan agreement with Deerfield, Deerfield could enforce its security interest,
which could further impact our revenues.

We must invest substantial sums in research and development (“R&D”) in order to remain competitive, and we may not fully recover these investments.

To  be  successful  in  the  highly-competitive  pharmaceutical  industry,  we  must  commit  substantial  resources  each  year  to  R&D  in  order  to  develop  new
products and enhance our technologies. In 2019, we spent $32.9 million on R&D, including on our FT218 product candidate and on Nouress, which was
approved  by  the  FDA  in  December  2019.  Our  ongoing  investments  in  R&D  for  FT218  as  well  as  possible  future  products  could  result  in  higher  costs
without a proportionate increase, or any increase, in revenues. The R&D process is lengthy and carries a substantial risk of failure. If our R&D does not
yield sufficient products that achieve commercial success, our future operating results will be adversely affected.

Our products may not reach the commercial market for a number of reasons.

Drug development is an inherently uncertain process with a high risk of failure at every stage of development. Successful R&D of pharmaceutical products
is  difficult,  expensive  and  time  consuming.  Many  product  candidates  fail  to  reach  the  market.  Our  success  will  depend  on  the  development  and  the
successful commercialization of new drugs, including additional previously unapproved marketed drugs (“UMD”) products, and products that utilize our
drug delivery technologies. If any of our additional

-18-

UMD  products  or  products  incorporating  our  drug  delivery  technologies  fails  to  reach  the  commercial  market,  our  future  revenues  would  be  adversely
affected.

Even if our products and current drug delivery technologies appear promising during development, there may not be successful commercial applications
developed for them for a number of reasons, including:

•

•

•

•

•

•

the FDA, the European Medicines Agency (“EMA”), the competent authority of an EU Member State or an Institutional Review Board (“IRB”),
or an Ethics Committee (EU equivalent to IRB), or our partners may delay or halt applicable clinical trials;
we or our partners may face slower than expected rate of patient recruitment and enrollment in clinical trials, or may devote insufficient funding to
the clinical trials;
our drug delivery technologies and drug products may be found to be ineffective or to cause harmful side effects, or may fail during any stage of
pre-clinical testing or clinical trials;
we or our partners may find that certain products cannot be manufactured on a commercial scale and, therefore, may not be economical or feasible
to produce;
we or our partners may face delays in completing our clinical trials due to circumstances outside of our control, including natural disasters, labor
or civil unrest, global health concerns or pandemics or acts of war or terrorism; or
our products could fail to obtain regulatory approval or, if approved, could fail to achieve market acceptance, could fail to be included within the
pricing and reimbursement schemes of the U.S. or EU Member States, or could be precluded from commercialization by proprietary rights of third
parties.

We may rely on collaborations with third parties to commercialize certain of our products in development, particularly products using our drug delivery
technologies, and such strategy involves risks that could impair our prospects for realizing profits from such products.

We expect that the commercialization of some of our products in development, which utilize our drug delivery technologies, may require collaboration with
third-party  partners  involving  strategic  alliances,  licenses,  product  divestitures  or  other  arrangements.  We  may  not  be  successful  in  entering  into  such
collaborations on favorable terms, if at all, or our collaboration partners may not adequately perform under such arrangements, and as a result our ability to
commercialize these products will be negatively affected and our prospects will be impaired.

Our products may not gain market acceptance.

Our  products  and  technologies  may  not  gain  market  acceptance  among  physicians,  patients,  healthcare  payor  and  medical  communities.  The  degree  of
market acceptance of any product or technology will depend on a number of factors, including, but not limited to:

•

•

•
•
•
•
•
•
•
•

the scope of regulatory approvals, including limitations or warnings in a product’s regulatory-approved labeling; or other restrictions under a FDA
Risk Evaluations and Mitigations Strategies (“REMS”), program;
in the case of any new UMD product we may successfully pursue, whether and the extent to which the FDA removes competing products from the
market;
in the case of our product candidates that are controlled substances the U.S. Drug Enforcement Administration (“DEA”), scheduling classification;
demonstration of the clinical safety and efficacy of the product or technology;
the absence of evidence of undesirable side effects of the product or technology that delay or extend trials;
the lack of regulatory delays or other regulatory actions;
its cost-effectiveness and related access to payor coverage;
its potential advantage over alternative treatment methods;
the availability of third-party reimbursement; and
the marketing and distribution support it receives.

If any of our products or technologies fails to achieve market acceptance, our ability to generate additional revenue will be limited, which would have a
material adverse effect on our business.

The  development  of  several  of  our  drug  delivery  technologies  and  products  depends  on  the  services  of  a  single  provider  and  any  interruption  of
operations of such provider could significantly delay or have a material adverse effect on our product pipeline.

Currently, we use a single source provider for the development, supply of clinical materials and potentially the supply of commercial

-19-

batches for several of our products incorporating our drug delivery technologies. Any disruption in the operations of this provider or if this provider fails to
supply acceptable quantity and quality materials or services to us for any reason, such disruption or failure could delay our product development and could
have a material adverse effect on our business, financial condition and results of operations. In case of a disruption, we may need to establish alternative
manufacturing  sources  for  our  drug  delivery  products,  and  this  would  likely  lead  to  substantial  production  delays  as  we  build  or  locate  replacement
facilities and seek to satisfy necessary regulatory requirements.

We depend on a limited number of suppliers for the manufacturing of our products and certain raw materials used in our products and any failure of
such suppliers to manufacture or supply sufficient quantities of product or these raw materials could have a material adverse effect on our business.

Currently, we depend on a limited number of contract manufacturing organizations (“CMOs”), for three products, Bloxiverz, Vazculep and Akovaz, from
which we derive our revenues. Additionally, we purchase certain raw materials used in our products from a limited number of suppliers, including a single
supplier  for  certain  key  ingredients.  If  the  supplies  of  these  products  or  materials  were  interrupted  for  any  reason,  including  but  not  limited  to,  natural
disasters, labor or civil unrest, global health concerns or pandemics or acts of war or terrorism, the manufacturing and supply of certain products could be
delayed. If  the  supplies  of  these  products  or  materials  were  interrupted  for  any  reason,  our  manufacturing  and  marketing  of  certain  products  could  be
delayed. These delays could be extensive and expensive, especially in situations where a substitution was not readily available or required variations of
existing  regulatory  approvals  and  certifications  or  additional  regulatory  approval.  For  example,  an  alternative  supplier  may  be  required  to  pass  an
inspection by the FDA, EMA or the competent authorities of EU Member States for compliance with current cGMP, requirements before supplying us with
product or before we may incorporate that supplier’s ingredients into the manufacturing of our products by our contract, development, and manufacturing
organizations (“CDMOs”). Failure to obtain adequate supplies in a timely manner could have a material adverse effect on our business, financial condition
and results of operations.

If our competitors develop and market technologies or products that are safer or more effective than ours, or obtain regulatory approval and market
such technologies or products before we do, our commercial opportunity will be diminished or eliminated.

Competition  in  the  pharmaceutical  and  biotechnology  industry  is  intense  and  is  expected  to  increase.  We  compete  with  academic  laboratories,  research
institutions,  universities,  joint  ventures  and  other  pharmaceutical  and  biotechnology  companies,  including  other  companies  developing  drug  delivery
technologies or niche brand or generic specialty pharmaceutical products. Some of these competitors may also be our business partners.

Our drug delivery technologies compete with technologies provided by several other companies. In particular, delivery technologies and products, could be
developed that, if successful, could compete against our drug delivery technologies or products. Among the many experimental therapies being tested in the
U.S. and in the EU, there may be some that we do not now know of that may compete with our drug delivery technologies or products in the future. These
new biological or chemical products may be safer or may work better than our products.

With respect to our UMD products, the FDA has approved generic versions or previously filed NDAs of our marketed products and may approve additional
generic versions in the future.

Many of our competitors have substantially greater financial, technological, manufacturing, marketing, managerial and R&D resources and experience than
we  do.  Furthermore,  acquisitions  of  competing  drug  delivery  companies  by  large  pharmaceutical  companies  could  enhance  our  competitors’  resources.
Accordingly, our competitors may succeed in developing competing technologies and products, obtaining regulatory approval and gaining market share for
their products more rapidly than we do.

Our revenues may be negatively affected by healthcare reforms and increasing pricing pressures.

Future prices for our pharmaceutical products and medical devices will be substantially affected by reimbursement policies of third-party payors such as
government healthcare programs, private insurance plans and managed care organizations; by our contracts with the drug wholesalers who distribute our
products;  and  by  competitive  market  forces  generally.  In  recent  years,  third-party  payors  have  been  exerting  downward  pressure  on  prices  at  which
products will be reimbursed, and the drug wholesale industry has been undergoing consolidation which gives greater market power to the remaining, larger
drug  wholesalers.  In  the  U.S.,  the  Trump  administration  has  made  public  and  social  media  statements  causing  uncertainty  as  to  future  federal  U.S.
government policies regulating drug prices. Further, the trend toward increased availability of generic products has contributed to overall pricing pressures
in the pharmaceutical industry. Additionally, on December 18, 2019, President Trump, the U.S. Department of Health and Human Services, and the FDA
issued a notice of proposed rulemaking that, if finalized, would allow for the importation of certain prescription drugs from Canada. FDA also issued a
Draft Guidance document outlining a potential

-20-

pathway for manufacturers to obtain an additional National Drug Code (“NDC”), for an FDA-approved drug that was originally intended to be marketed in
a foreign country and that was authorized for sale in that foreign country. The regulatory and market implications of the notice of proposed rulemaking and
Draft Guidance are unknown at this time, but legislation, regulations or policies allowing the reimportation of drugs, if enacted and implemented, could
decrease the price we receive for our products and adversely affect our future revenues and prospects for profitability. Similarly, any future changes in laws,
regulations, practices or policies, in the drug wholesale industry, or in the prevalence of generic products, may adversely affect our financial condition and
results of operations.

If we cannot keep pace with the rapid technological change in our industry, we may lose business, and our products and technologies could become
obsolete or noncompetitive.

Our success also depends, in part, on maintaining a competitive position in the development of products and technologies in a rapidly evolving field. Major
technological  changes  can  happen  quickly  in  the  biotechnology  and  pharmaceutical  industries.  If  we  cannot  maintain  competitive  products  and
technologies, our competitors may succeed in developing competing technologies or obtaining regulatory approval for products before us, and the products
of our competitors may gain market acceptance more rapidly than our products. Such rapid technological change, or the development by our competitors of
technologically improved or different products, could render our products or technologies obsolete or noncompetitive.

We may fail to effectively execute our business strategy.

Our business strategy is to continue our UMD program by commercializing our fourth UMD product, Nouress, as well as potentially seek FDA approval
for and commercialize additional future UMD product candidates, and to continue to seek FDA approval for FT218, which completed enrollment for its
Phase 3 clinical trial and for which we expect topline data in the second quarter of 2020. There can be no assurance that we will be successful in any of
these objectives; and a failure in any of these objectives could negatively impact our business and operating results.

Failure to comply with domestic and international privacy and security laws could result in the imposition of significant civil and criminal penalties.

The costs of compliance with privacy and security laws, including protecting electronically stored information from cyber-attacks, and potential liability
associated  with  any  compliance  failures  could  adversely  affect  our  business,  financial  condition  and  results  of  operations.  We  are  subject  to  various
domestic and international privacy and security regulations, including but not limited to HIPAA and the General Data Protection Regulation (“GDPR”),
(Regulation EU 2016/679). HIPAA mandates, among other things, the adoption of uniform standards for the electronic exchange of information in common
healthcare transactions, as well as standards relating to the privacy and security of individually identifiable health information, which require the adoption
of administrative, physical and technical safeguards to protect such information. In addition, many U.S. states have enacted comparable laws addressing the
privacy and security of health information, some of which are more stringent than HIPAA. GDPR requires Avadel to ensure personal data collected by
Avadel is gathered legally and under strict conditions and to protect such personal data from misuse and exploitation. If Avadel fails to comply with GDPR,
we will face significant fines and penalties that could adversely affect our business, financial condition and results of operations.

Our effective tax rate could be highly volatile and could adversely affect our operating results.

Our future effective tax rate may be adversely affected by a number of factors, many of which are outside of our control, including:

•
•
•
•
•
•
•

•
•

the jurisdictions in which profits are determined to be earned and taxed;
changes in the valuation of our deferred tax assets and liabilities;
the resolution of issues arising from tax audits with various tax authorities;
changes in share-based compensation expense;
changes in domestic or international tax laws or the interpretation of such tax laws;
changes in available tax credits;
increases  in  expenses  not  deductible  for  tax  purposes,  including  increases  in  the  fair  value  of  related  party  payables,  write-offs  of  acquired  in-
process R&D and impairment of goodwill in connection with acquisitions;
adjustments to estimated taxes upon finalization of various tax returns;
the tax effects of purchase accounting for acquisitions that may cause fluctuations between reporting periods.

Any significant increase in our future effective tax rates could impact our results of operations for future periods adversely.

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

As of December 31, 2019, we had U.S. federal net operating loss carryforwards of approximately $75.5 million due to prior period losses, some of which,
if not utilized, will expire in 2034 and 2035 for federal tax purposes. Approximately $10.4 million of these net operating loss carryforwards could expire
unused  and  be  unavailable  to  offset  future  income  tax  liabilities,  which  could  adversely  affect  our  profitability.  The  $10.4  million  of  U.S.  federal  net
operating loss carryforwards are subject to an annual limitation as a result of the FSC acquisition under Internal Revenue Code Section 382 and may not be
fully utilized before they expire.

Under U.S. federal tax legislation enacted in 2017, informally titled the Tax Cuts and Jobs Act (“Tax Act”), U.S. federal net operating losses incurred in
2018 and in future years may be carried forward indefinitely, but the deductibility of such U.S. federal net operating losses is limited. Under Sections 382
and 383 of the U.S. Internal Revenue Code of 1986 (the “Code”) if a corporation undergoes an “ownership change” (generally defined as a greater than 50
percentage-point cumulative change (by value) in the equity ownership of certain shareholders over a rolling three-year period), the corporation’s ability to
use its pre-change net operating losses and other pre-change tax attributes to offset its post-change taxable income or taxes may be limited. We may also
experience ownership changes as a result of this offering or future issuances of our stock or as a result of subsequent shifts in our stock ownership, some of
which are outside our control. We have completed an analysis to determine that no events have been triggered in the past. If any ownership changes are
determined to be triggered in the future, our ability to use our current net operating losses to offset post-change taxable income or taxes would be subject to
limitation. We will be unable to use our net operating losses if we do not attain profitability sufficient to offset our available net operating losses prior to
their expiration.

As of December 31, 2019, we had approximately $95.8 million of net operating losses in Ireland that do not have an expiration date. While these losses do
not have an expiration date, substantial changes in the activities performed in these jurisdictions could have an impact on our ability to utilize these tax
attributes in the future.

We outsource important activities to consultants, advisors and outside contractors.

We outsource many key functions of our business and therefore rely on a substantial number of consultants, advisors and outside contractors. If we are
unable to effectively manage our outsourced activities or if the quality or accuracy of the services provided by such third parties is compromised for any
reason,  our  development  activities  may  be  extended,  delayed  or  terminated  which  would  have  an  adverse  effect  on  our  development  program  and  our
business.

We depend on key personnel to execute our business plan. If we cannot attract and retain key personnel, we may not be able to successfully implement
our business plan.

Our success depends in large part upon our ability to attract and retain highly qualified personnel. During our operating history, we have assigned many key
responsibilities  within  our  Company  to  a  relatively  small  number  of  individuals,  each  of  whom  has  played  key  roles  in  executing  various  important
components of our business. We do not maintain material key person life insurance for any of our key personnel. If we lose the services of Greg Divis, our
Chief Executive Officer, or other members of our senior executive team, we may have difficulty executing our business plan in the manner we currently
anticipate. Further, because each of our key personnel is involved in numerous roles in various components of our business, the loss of any one or more of
such individuals could have an adverse effect on our business.

Risks Related to Our Intellectual Property

If we cannot adequately protect our intellectual property and proprietary information, we may be unable to effectively compete.

Our success depends, in part, on our ability to obtain and enforce patents and other intellectual property rights for our products and technology, including
our drug delivery technologies, and to preserve our trade secrets and other proprietary information. If we cannot do so, our competitors may exploit our
technologies and deprive us of the ability to realize revenues and profits from our products and technologies.

To the extent any of our products may benefit from protections afforded by patents, we face the risk that patent law relating to the scope of claims in the
pharmaceutical and biotechnology fields is continually evolving and can be the subject of uncertainty and may change in a way that would limit protection.
Our  patents  may  not  be  exclusive,  valid  or  enforceable.  For  example,  our  patents  may  not  protect  us  against  challenges  by  companies  that  submit  drug
marketing  applications  to  the  FDA,  or  the  competent  authorities  of  EU  Member  States  or  other  jurisdictions  in  which  we  may  attempt  to  compete,  in
particular  where  such  applications  rely,  at  least  in  part,  on  safety  and  efficacy  data  from  our  products  or  our  business  partners’  products.  In  addition,
competitors may obtain patents that may have an adverse effect on our ability to conduct business, or they may discover ways to circumvent our patents.
The scope of any patent protection may not be sufficiently broad to cover our products or to exclude competing products. Any

-22-

patent  applications  we  have  made  or  may  make  relating  to  our  potential  products  or  technologies  may  not  result  in  patents  being  issued.  Even  after
issuance, our patents may be challenged in the courts or patent offices in the U.S. and abroad. Such challenges may result in loss of exclusivity or in patent
claims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to stop others from using or commercializing
similar or identical product candidates, or limit the duration of the patent protection of our product candidates. Further, patent protection once obtained is
limited in time, after which competitors may use the covered product or technology without obtaining a license from us. Because of the time required to
obtain regulatory marketing approval, the remaining period of effective patent protection for a marketed product is frequently substantially shorter than the
full duration of the patent. While a patent term extension can be requested under certain circumstances, the grant of such a request is not guaranteed.

Our  partnerships  with  third  parties  expose  us  to  risks  that  they  will  claim  intellectual  property  rights  on  our  inventions  or  fail  to  keep  our  unpatented
products or technology confidential.

If we are unable to protect the confidentiality of our trade secrets, the value of our technology could be materially adversely affected and our business
would be harmed.

We also rely on trademarks, copyrights, trade secrets and know-how to develop, maintain and strengthen our competitive position.

To  protect  our  products,  trade  secrets  and  proprietary  technologies,  we  rely,  in  part,  on  confidentiality  agreements  with  our  employees,  suppliers,
consultants, advisors and partners. These agreements may not provide adequate protection for our trade secrets and other proprietary information in the
event of any unauthorized use or disclosure, or if others lawfully develop the information. If these agreements are breached, we cannot be certain we will
have  adequate  remedies.  Further,  we  cannot  guarantee  that  third  parties  will  not  know,  discover  or  independently  develop  equivalent  proprietary
information or technologies, or that they will not gain access to our trade secrets or disclose our trade secrets to the public. Therefore, we cannot guarantee
we  can  maintain  and  protect  unpatented  proprietary  information  and  trade  secrets.  Misappropriation  or  other  loss  of  our  intellectual  property  would
adversely affect our competitive position and may cause us to incur substantial litigation or other costs.

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

Changes  in  either  the  patent  laws  or  interpretation  thereof  in  the  U.S.  or  in  ex-U.S.  jurisdictions  could  increase  uncertainties  and  costs  surrounding  the
prosecution of patent applications and the enforcement or defense of issued patents. For example, the Leahy-Smith America Invents Act of 2011 (“AIA”),
changed  the  previous  U.S.  “first-to-invent”  system  to  the  current  system  that  awards  a  patent  to  the  “first-inventor-to-file”  for  an  application  for  a
patentable invention. This change alters the pool of available materials that can be used to challenge patents in the U.S. and limits the ability to rely on prior
research  to  lay  claim  to  patent  rights.  Under  the  current  system,  disputes  are  resolved  through  new  derivation  proceedings,  and  the  AIA  includes
mechanisms  to  allow  challenges  to  issued  patents  in  reexamination,  inter partes  review  and  post  grant  proceedings.  The  AIA  also  includes  bases  and
procedures that may make it easier for competitors to challenge our patents, which could result in increased competition and have a material adverse effect
on our business and results of operations. The AIA may also make it harder to challenge third-party patents and place greater importance on being the first
inventor to file a patent application on an invention. The AIA amendments to patent filing and litigation procedures in the U.S. may result in litigation
being more complex and expensive and divert the efforts of our technical and management personnel.

In addition, the patent positions of companies in the development and commercialization of pharmaceuticals may be particularly uncertain. Depending on
future  actions  by  the  U.S.  Congress,  the  U.S.  federal  courts,  and  the  USPTO,  or  by  similarly  legislative,  judicial,  and  regulatory  authorities  in  other
jurisdictions,  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.

Third parties may claim that our products infringe their rights, and we may incur significant costs resolving these claims.

Third parties may claim infringement of their patents and other intellectual property rights by the manufacture, use, import, offer for sale or sale of our drug
delivery  technologies  or  our  other  products.  For  example,  an  Orange  Book  patent  exists  related  to  Exela’s  currently  marketed  cysteine  hydrochloride
injection product. In this regard, Exela filed a complaint against us and our subsidiary, Avadel Legacy Pharmaceuticals, LLC (“Avadel Legacy”), in the
United States District for the District of Delaware in January of 2020 alleging infringement of that Orange Book patent by our recently-approved Nouress
product. As another example, approximately 14 Orange Book patents exist related to Jazz Pharmaceuticals’ currently marketed sodium oxybate product,
and, in connection with us seeking regulatory approval for FT218, Jazz may allege that FT218 infringes its patents or other intellectual property rights and
file suit to prevent us from commercializing FT218. In response to any claim of infringement, we may choose

-23-

or  be  forced  to  seek  licenses,  defend  infringement  actions  or  challenge  the  validity  or  enforceability  of  those  patent  rights  in  court  or  administrative
proceedings. If we cannot obtain required licenses on commercially reasonably terms, or at all, are found liable for infringement or are not able to have
such  patent  rights  declared  invalid  or  unenforceable,  our  business  could  be  materially  harmed.  We  may  be  subject  to  claims  (and  even  held  liable)  for
significant  monetary  damages  (including  enhanced  damages  and/or  attorneys’  fees),  encounter  significant  delays  in  bringing  products  to  market  or  be
precluded  from  the  manufacture,  use,  import,  offer  for  sale  or  sale  of  products  or  methods  of  drug  delivery  covered  by  the  patents  of  others.  Even  if  a
license  is  available,  it  may  not  be  available  on  commercially  reasonable  terms  or  may  be  non-exclusive,  which  could  result  in  our  competitors  gaining
access to the same intellectual property. We may not have identified, or be able to identify in the future, U.S. or foreign patents that pose a risk of potential
infringement claims.

Parties making claims against us may be able to sustain the costs of patent litigation more effectively than we can because they have substantially greater
resources. In addition, any claims, with or without merit, that our products or drug delivery technologies infringe proprietary rights of third parties could be
time-consuming, result in costly litigation or divert the efforts of our technical and management personnel, any of which could disrupt our relationships
with our partners and could significantly harm our financial positions and operating results.

If we or our partners are required to obtain licenses from third parties, our revenues and royalties on any commercialized products could be reduced.

The  development  of  certain  products  based  on  our  drug  delivery  technologies  may  require  the  use  of  raw  materials  (e.g.,  proprietary  excipient),  active
ingredients, drugs (e.g., proprietary proteins) or technologies developed by third parties. The extent to which efforts by other researchers have resulted or
will result in patents and the extent to which we or our partners are forced to obtain licenses from others, if available, on commercially reasonable terms is
currently  unknown.  If  we  or  our  partners  must  obtain  licenses  from  third  parties,  fees  may  be  required  for  such  licenses,  which  could  reduce  the  net
revenues and royalties we receive on commercialized products that incorporate our drug delivery technologies.

Security breaches and other disruptions could compromise confidential information and expose us to liability and cause our business and reputation to
suffer.

In the ordinary course of our business, we collect and store on our networks various intellectual property including our proprietary business information
and that of our customers, suppliers and business partners. The secure maintenance and transmission of this information is critical to our operations and
business strategy. Despite our security measures, our information systems and infrastructure may be vulnerable to disruptions such as computer hacking,
phishing attacks, ransomware, dissemination of computer viruses, worms and other destructive or disruptive software, attacks by hackers or breached due
to employee error, malfeasance or other disruptions. Any such breach could compromise our networks and the information stored there could be accessed,
publicly disclosed, lost or stolen. Any such access, disclosure or other loss of information could result in legal claims or proceedings, investigations by
regulatory authorities in the U.S. and EU Member States, disruption to our operations and damage to our reputation, any of which could adversely affect
our business.

We could suffer financial loss or the loss of valuable confidential information. Although we develop and maintain systems and controls designed to prevent
these  events  from  occurring  and  we  have  a  process  to  identify  and  mitigate  threats,  the  development  and  maintenance  of  these  systems,  controls  and
processes is costly and requires ongoing monitoring and updating as technologies change and efforts to overcome security measures become increasingly
sophisticated. Moreover, despite our efforts, the possibility of these events occurring cannot be eliminated entirely and there can be no assurance that any
measures we take will prevent cyber-attacks or security breaches that could adversely affect our business.

Patent terms may be inadequate to protect our competitive position on our product candidates for an adequate amount of time.

Patents have a limited lifespan. In the U.S., if all maintenance fees are timely paid, the natural expiration of a patent is generally 20 years from its earliest
U.S.  non-provisional  filing  date.  Various  extensions  may  be  available,  but  the  life  of  a  patent,  and  the  protection  it  affords,  is  limited.  Even  if  patents
covering  our  product  candidates  are  obtained,  once  the  patent  life  has  expired,  we  may  be  open  to  competition  from  competitive  products,  including
generics or biosimilars. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting
such  candidates  might  expire  before  or  shortly  after  such  candidates  are  commercialized.  As  a  result,  our  owned  and  licensed  patent  portfolio  may  not
provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

-24-

We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time consuming and
unsuccessful.

Competitors may infringe our patents or other intellectual property. If we were to initiate legal proceedings against a third party to enforce a patent covering
our product(s) or product candidate(s), the defendant could counterclaim that the patent is invalid and/or unenforceable. In patent litigation in the U.S.,
defendant counterclaims alleging invalidity and/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,  written  description  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.  There  is  risk  that  a  court  could  rule  in  favor  of  the  defendant  with  respect  to  such  a  counterclaim  of  patent
invalidity and/or unenforceability.

Interference or derivation proceedings provoked by third parties or brought by us or declared by the USPTO may be necessary to determine the priority of
inventions with respect to our patents or patent applications. An unfavorable outcome could require us to cease using the related technology or to attempt to
license rights to it from the prevailing party. Our business could be harmed if the prevailing party does not offer us a license on commercially reasonable
terms or at all, or if a non-exclusive license is offered and our competitors gain access to the same technology. Our defense of litigation or interference or
derivation proceedings may fail and, even if successful, may result in substantial costs and distract our management and other employees. In addition, the
uncertainties  associated  with  litigation  could  have  a  material  adverse  effect  on  our  ability  to  raise  the  funds  necessary  to  continue  our  clinical  trials,
continue  our  research  programs,  license  necessary  technology  from  third  parties,  or  enter  into  development  partnerships  that  would  help  us  bring  our
product candidates to market.

Because of the substantial amount of discovery that can occur in connection with intellectual property-related litigation and/or administrative proceedings,
there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation/proceeding. There could also be
public announcements of the results of hearings, motions, or other interim proceedings or developments. If securities analysts or investors perceive these
results to be negative, it could have a material adverse effect on the price of our common stock.

We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed confidential information of
third parties or that our employees have wrongfully used or disclosed alleged trade secrets of their former employers.

We employ or may employ individuals who were previously employed at universities or other biotechnology or pharmaceutical companies, including our
competitors  or  potential  competitors.  Although  we  endeavor  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, we may be subject to claims that we or our employees, consultants or independent
contractors have inadvertently or otherwise used or disclosed intellectual property, including trade secrets or other proprietary information, of any of our
employee’s 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  any  awarded  monetary  damages,  we  may  lose  valuable  intellectual  property  rights  or  personnel,  which  could  adversely  impact  our
business. Even if we are successful in defending against such claims, litigation could result in substantial costs and/or be a distraction to management and
other employees.

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

Periodic  maintenance  fees,  renewal  fees,  annuity  fees  and  various  other  governmental  fees  on  patents  and/or  applications  will  be  due  to  be  paid  to  the
USPTO and various governmental patent agencies outside of the U.S. in several stages over the lifetime of the patents and/or applications. We rely on our
outside  counsel  to  coordinate  payment  of  these  fees  due  to  patent  agencies.  The  USPTO  and  various  non-U.S.  governmental  patent  agencies  require
compliance  with  a  number  of  procedural,  documentary,  fee  payment  and  other  similar  provisions  during  the  patent  application  process.  We  employ
reputable law firms and other professionals to help us comply, and 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. However, there are situations 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, our competitors might be able to enter
the market and this circumstance would have a material adverse effect on our business.

We may not be able to protect our intellectual property rights throughout the world.

Filing, prosecuting and defending patents on our product candidates in all countries throughout the world would be prohibitively

-25-

expensive, and intellectual property rights in some countries outside the U.S. can be less extensive than those in the U.S. Consequently, we may not be able
to prevent third parties from practicing our inventions in all countries outside the U.S., or from selling or importing products made using our inventions in
and into the U.S. or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop
their own products and may also export infringing products to territories where we have patent protection, but enforcement is not as strong as that in the
U.S. These products may compete with our products and our patents or other intellectual property rights may not be effective or sufficient to prevent them
from competing.

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

Risks Related to Regulatory and Legal Matters

Our products will generally be subject to regulatory approval. If we or our pharmaceutical and biotechnology company partners do not obtain such
approvals, or if such approvals are delayed, our revenues may be adversely affected.

Our FT218 product, as well as products we may wish to market in the future, may not gain regulatory approval and reach the commercial market for a
variety of reasons.

In the U.S., federal, state and local government agencies, primarily the FDA, regulate all pharmaceutical products, including existing products and those
under  development.  Neither  we  nor  our  pharmaceutical  and  biotechnology  partners  can  control  whether  we  obtain  regulatory  approval  for  any  of  these
products or, if obtained, the timing thereof. There may be significant delays in expected product releases while attempting to obtain regulatory approval for
products incorporating our technologies. If we or our partners are not successful in timely obtaining such approvals, our revenues and profitability may
decline.

Applicants for FDA approval often must submit to the FDA extensive clinical and pre-clinical data, as well as information about product manufacturing
processes  and  facilities  and  other  supporting  information.  Varying  interpretations  of  the  data  obtained  from  pre-clinical  and  clinical  testing  could  delay,
limit or prevent regulatory approval of a drug product. The FDA also may require us, or our partners to conduct additional pre-clinical studies or clinical
trials.

Similarly, although we anticipate submitting applications for approval for our development products that rely on existing data to demonstrate safety and
effectiveness, the FDA may determine that additional studies particular to our products are necessary. If the FDA requires such additional studies, it would
impact development plans for those products.

Changes in FDA approval policy during the development period, or changes in regulatory review for each submitted new product application, also may
delay an approval or result in rejection of an application. For instance, under the FDAAA, we or our partners may be required to develop REMS to ensure
the safe use of product candidates. If the FDA disagrees with such REMS proposals, it may be more difficult and costly to obtain regulatory approval for
our product candidates. Similarly, FDAAA provisions may make it more likely that the FDA will refer a marketing application for a new product to an
advisory committee for review, evaluation and recommendation as to whether the application should be approved. This review may add to the time for
approval,  and,  although  the  FDA  is  not  bound  by  the  recommendation  of  an  advisory  committee,  objections  or  concerns  expressed  by  an  advisory
committee may cause the FDA to delay or deny approval.

The FDA has substantial discretion in the approval process and may disagree with our or our partners’ interpretations of data and information submitted in
an application, which also could cause delays of an approval or rejection of an application. Even if the FDA approves a product, the approval may limit the
uses or indications for which the product may be marketed, restrict distribution of the product or require further studies.

The FDA may also withdraw product approvals for failure to comply with regulatory requirements or if problems follow initial marketing. In the same way,
medicinal products for supply on the EU market are subject to marketing authorization by either the European Commission, following an opinion by the
EMA, or by the competent authorities of EU Member States. Applicants for

-26-

marketing authorization must submit extensive technical and clinical data essentially in the form of the ICH Common Technical Document. The data is
subject to extensive review by the competent authorities, and after such review the data may be considered inappropriate or insufficient. If applications for
marketing authorization by pharmaceutical and biotechnology company partners are delayed or rejected, if the therapeutic indications for which the product
is approved are limited, or if conditional marketing authorization imposing post-marketing clinical trials or surveillance is imposed, our revenues, operating
results and liquidity may decline and earnings may be negatively impacted.

Our products are subject to continuing regulation, and we on our own, and in conjunction with our pharmaceutical partners, may be subject to adverse
consequences if we or they fail to comply with applicable regulations.

We, on our own, and in conjunction with our pharmaceutical partners will be subject to extensive regulatory requirements for our and the co-developed
products and product candidates, even if the products receive regulatory approval. These regulations are wide-ranging and govern, among other things:

•
•
•
•
•
•
•
•
•
•
•
•
•

adverse drug experiences and other reporting requirements;
product promotion and marketing;
APIs and/or product manufacturing, including cGMP compliance;
record keeping;
distribution of drug samples;
required clinical trials and/or post-marketing studies;
authorization renewal procedures;
authorization variation procedures;
compliance with any required REMS;
updating safety and efficacy information;
processing of personal data;
use of electronic records and signatures; and
changes to product manufacturing or labeling.

Clinical development of drugs is costly and time-consuming, and the outcomes are uncertain. A failure to prove that our product candidates are safe
and effective in clinical trials could materially and adversely affect our business, financial condition, results of operations and growth prospects.

We have made significant investments in our REST-ON Phase 3 clinical trial of FT218. Clinical trials are expensive and can take many years to complete,
and the outcome is uncertain. Failure can occur at any time during the clinical trial process. The results of preclinical studies and early clinical trials of
potential medicine candidates may not be predictive of the results of later-stage clinical trials. Drug candidates in later stages of clinical trials may fail to
show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical testing. Any failure of our REST-ON
Phase 3 clinical trial would prevent or delay the potential approval and commercialization of our sodium oxybate product, which would materially and
adversely affect our business, financial condition, results of operations and growth prospects.

In addition to issues relating to the results generated in clinical trials, clinical trials can be delayed or halted for a variety of reasons, including:

•
•

•
•
•
•
•
•

failure in obtaining regulatory approval to commence a trial;
failure in reaching agreement on acceptable terms with prospective contract research organizations (“CROs”) and clinical trial sites, the terms of
which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;
failure in obtaining institutional review board or ethics committee approval at each site;
failure in recruiting suitable patients to participate in a trial;
failure in having patients complete a trial or return for post-treatment follow-up;
failure in clinical sites dropping out of a trial;
failure in adding new sites; or
failure in manufacturing sufficient quantities of medicine candidates for use in clinical trials.

We rely and expect to rely on CROs and clinical trial sites to ensure the proper and timely conduct of our future clinical trials and while we have and intend
to have agreements governing their committed activities, we will have limited influence over their actual performance.

-27-

We  rely  on  third  parties  to  conduct  our  clinical  trials,  and  if  they  do  not  properly  and  successfully  perform  their  contractual,  legal  and  regulatory
duties, we may not be able to obtain regulatory approvals for or commercialize our drug product candidates.

We  rely  on  CROs  and  other  third  parties  to  assist  us  in  designing,  managing,  monitoring  and  otherwise  carrying  out  our  clinical  trials,  including  with
respect to site selection, contract negotiation and data management. We do not control these third parties and, as a result, they may not treat our clinical
studies as a high priority, which could result in delays. We are responsible for confirming that each of our clinical trials is conducted in accordance with its
general  investigational  plan  and  protocol,  as  well  as  the  FDA’s  and  non-U.S.  regulatory  agencies’  requirements,  commonly  referred  to  as  good  clinical
practices, for conducting, recording and reporting the results of clinical trials to ensure that the data and results are credible and accurate and that the trial
participants  are  adequately  protected.  The  FDA  and  non-U.S.  regulatory  agencies  enforce  good  clinical  practices  through  periodic  inspections  of  trial
sponsors, principal investigators and trial sites. If we, CROs or other third parties assisting us or our study sites fail to comply with applicable good clinical
practices, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or its non-U.S. counterparts may require us to perform
additional clinical trials before approving our marketing applications. We cannot assure you that, upon inspection, the FDA or non-U.S. regulatory agencies
will determine that any of our clinical trials comply with good clinical practices. In addition, our clinical trials must be conducted with product produced
under the FDA’s cGMP regulations and similar regulations outside of the U.S. Our failure, or the failure of our product suppliers, to comply with these
regulations may require us to repeat or redesign clinical trials, which would delay the regulatory approval process.

If third parties do not successfully carry out their duties under their agreements with us, if the quality or accuracy of the data they obtain is compromised
due to failure to adhere to our clinical protocols, including dosing requirements, or regulatory requirements, or if they otherwise fail to comply with clinical
trial  protocols  or  meet  expected  deadlines,  our  clinical  trials  may  not  meet  regulatory  requirements.  If  our  clinical  trials  do  not  meet  regulatory
requirements  or  if  these  third  parties  need  to  be  replaced,  our  clinical  trials  may  be  extended,  delayed,  suspended  or  terminated.  If  any  of  these  events
occur, we may not be able to obtain regulatory approval of our product candidates or succeed in our efforts to create approved line extensions for certain of
our existing products or generate additional useful clinical data in support of these products.

If we or our partners, including any CDMOs that we use, fail to comply with these laws and regulations, the FDA, the European Commission, competent
authorities of EU Member States, or other regulatory organizations, may take actions that could significantly restrict or prohibit commercial distribution of
our  products  and  products  that  incorporate  our  technologies.  If  the  FDA,  the  European  Commission  or  competent  authorities  of  EU  Member  States
determine that we are not in compliance with these laws and regulations, they could, among other things:

•
•
•
•
•
•
•
•
•

issue warning letters;
impose fines;
seize products or request or order recalls;
issue injunctions to stop future sales of products;
refuse to permit products to be imported into, or exported out of, the U.S. or the E.U.;
suspend or limit our production;
withdraw or vary approval of marketing applications;
order the competent authorities of EU Member States to withdraw or vary national authorization; and
initiate criminal prosecutions.

If FT218 is approved by the FDA, we may not obtain orphan drug marketing exclusivity.

Orphan drug status may be granted by the FDA to certain products intended to treat diseases and conditions that affect fewer than 200,000 individuals in
the U.S. or, if they affect more than 200,000 individuals in the U.S., there is no reasonable expectation of recovering the cost of developing and making the
product available in the U.S. for the applicable disease or condition.

Our proposed product FT218 obtained orphan drug designation for the treatment of narcolepsy from the FDA in January 2018. Generally, a product with
orphan drug designation that subsequently receives the first FDA approval for the disease or condition for which it has such designation will be entitled to
certain U.S. marketing exclusivity for a period of seven years. FT218 would not be the first sodium oxybate product with such FDA approval. However, if
the FDA concludes that FT218 is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care, the FDA
could award FT218 with such marketing exclusivity. A designated orphan drug may not receive orphan drug exclusivity. Among other factors, the FDA
will consider the results of our FT218 Phase 3 clinical trial with respect to the efficacy and safety of the previously approved sodium oxybate product.
Thus,  there  can  be  no  assurance  that  FT218  will  receive  orphan  drug  status  exclusivity,  if  approved.  In  addition,  even  if  such  orphan  drug  marketing
exclusivity  rights  were  granted  by  the  FDA,  such  exclusivity  rights  may  be  lost  if  the  FDA  later  determines  that  our  request  for  such  designation  was
materially defective or if the manufacturer is unable to assure sufficient

-28-

quantity  of  the  drug  to  meet  the  needs  of  patients  with  the  rare  disease  or  condition  to  be  treated  with  the  product.  Further,  even  with  respect  to  the
indications for which we have received orphan designation, we may not be the first to obtain marketing approval for any particular orphan indication due to
the uncertainties associated with developing pharmaceutical products, and thus, for example, approval of our product candidates could be blocked for seven
years if another company previously obtained approval and orphan drug exclusivity in the U.S. for the same drug and same condition.

We are subject to U.S. federal and state and international laws and regulations prohibiting “kickbacks” and false claims that, if violated, could subject
us to substantial penalties, and any challenges to or investigation into our practices under these laws could cause adverse publicity and be costly to
respond to, and thus could harm our business.

We are subject to extensive and complex U.S. federal and state and international laws and regulations, including but not limited to, health-care “fraud and
abuse”  laws,  such  as  anti-kickback  and  false  claims  laws  and  regulations  pertaining  to  government  benefit  program  reimbursement,  price  reporting  and
regulations, and sales and marketing practices. These laws and regulations are broad in scope and subject to evolving interpretations, which could require
us to incur substantial costs associated with compliance or to alter one or more of our sales or marketing practices. In addition, violations of these laws, or
allegations of such violations, could disrupt our business and result in a material adverse effect on our revenues, profitability, and financial condition. In the
current environment, there appears to be a greater risk of investigations of possible violations of these laws and regulations. This increased risk is reflected
by recent enforcement activity and pronouncements by the US Office of Inspector General of the Department of Health and Human Services that it intends
to continue to vigorously pursue fraud and abuse violations by pharmaceutical companies, including through the potential to impose criminal penalties on
pharmaceutical company executives. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights,
those actions could have a significant impact on our business, including the imposition of significant fines or other sanctions.

Healthcare reform and restrictions on reimbursements may limit our financial returns.

Our  ability  to  successfully  commercialize  our  products  and  technologies  may  depend  on  the  extent  to  which  the  government  health  administration
authorities, the health insurance funds in the EU Member States, private health insurers and other third-party payor in the U.S. will reimburse consumers
for the cost of these products, which would affect the volume of drug products sold by pharmaceutical and biotechnology companies that incorporate our
technology into their products. Third party payor are increasingly challenging both the need for, and the price of, novel therapeutic drugs and uncertainty
exists  as  to  the  reimbursement  status  of  newly  approved  therapeutics.  The  commercial  success  of  our  products  depends  in  part  on  the  conditions  under
which products incorporating our technology are reimbursed. Adequate third-party reimbursement may not be available for such drug products to enable us
to  maintain  price  levels  sufficient  to  realize  an  appropriate  return  on  our  investments  in  research  and  product  development,  which  could  materially  and
adversely  affect  our  business.  We  cannot  predict  the  effect  that  changes  in  the  healthcare  system,  especially  cost  containment  efforts,  may  have  on  our
business. In particular, it is difficult to predict the effect of health care reform legislation enacted in the U.S. in 2010, certain provisions of which are still
subject  to  regulatory  implementation,  further  legislative  change  and  ongoing  judicial  review.  Any  such  changes  or  changes  due  to  future  legislation
governing the pricing and reimbursement of healthcare products in the EU Member States may adversely affect our business.

Regulatory reforms may adversely affect our ability to sell our products profitably.

From time to time, the U.S. Congress, the Council of the European Union and the European Parliament, as well as the legislators of the EU Member States,
adopt changes to the statutes that the FDA, the European Commission and the competent authorities of the EU Member States enforce in ways that could
significantly affect our business. In addition, the FDA, the European Commission and the competent authorities of the EU Member States often issue new
regulations or guidance, or revise or reinterpret their current regulations and guidance in ways that may significantly affect our business and our products. It
is impossible to predict whether legislative changes will be enacted or FDA, EU or EU Member State’s regulations, guidance or interpretations changed,
and what the impact of any such changes may be. Any such changes could have a significant impact on the path to approval of our proposed products or of
competing products, and on our obligations and those of our pharmaceutical industry partners.

We and companies to which we have licensed, or will license our products or drug delivery technologies and subcontractors we engage for services
related to the development and manufacturing of our products are subject to extensive regulation by the FDA and other regulatory authorities. Our and
their failure to meet strict regulatory requirements could adversely affect our business.

We,  and  companies  to  which  we  license  our  products  or  drug  delivery  technologies,  as  well  as  companies  acting  as  subcontractors  for  our  product
developments, including but not limited to non-clinical, pre-clinical and clinical studies, and manufacturing, are subject to extensive regulation by the FDA,
other domestic regulatory authorities and equivalent foreign regulatory authorities,

-29-

particularly the European Commission and the competent authorities of EU Member States. Those regulatory authorities may conduct periodic audits or
inspections  of  the  applicable  facilities  to  monitor  compliance  with  regulatory  standards  and  we  remain  responsible  for  the  compliance  of  our
subcontractors. If the FDA or another regulatory authority finds failure to comply with applicable regulations, the authority may institute a wide variety of
enforcement actions, including:

•
•
•
•
•
•
•
•
•
•

warning letters or untitled letters;
fines and civil penalties;
delays in clearing or approving, or refusal to clear or approve, products;
withdrawal, suspension or variation of approval of products; product recall or seizure;
orders to the competent authorities of EU Member States to withdraw or vary national authorization;
orders for physician notification or device repair, replacement or refund;
interruption of production;
operating restrictions;
injunctions; and
criminal prosecution.

Any adverse action by a competent regulatory agency could lead to unanticipated expenditures to address or defend such action and may impair our ability
to produce and market applicable products, which could significantly impact our revenues and royalties that we receive from our customers.

We may face product liability claims related to clinical trials for our products or their misuse.

The testing, including through clinical trials, manufacturing and marketing, and the use of our products may expose us to potential product liability and
other claims. If any such claims against us are successful, we may be required to make significant compensation payments. Any indemnification that we
have obtained, or may obtain, from CROs or pharmaceutical and biotechnology companies or hospitals conducting human clinical trials on our behalf may
not protect us from product liability claims or from the costs of related litigation. Insurance coverage is expensive and difficult to obtain, and we may be
unable  to  obtain  coverage  in  the  future  on  acceptable  terms,  if  at  all.  We  currently  maintain  general  liability  insurance  and  product  liability  and  recall
insurance. We cannot be certain that the coverage limits of our insurance policies or those of our strategic partners will be adequate. If we are unable to
obtain sufficient insurance at an acceptable cost, a product liability claim or recall could adversely affect our financial condition.

Similarly, any indemnification we have obtained, or may obtain, from pharmaceutical and biotechnology companies with whom we are developing, or will
develop, our products may not protect us from product liability claims from the consumers of those products or from the costs of related litigation.

If we use hazardous biological and/or chemical materials in a manner that causes injury, we may be liable for significant damages.

Our R&D activities involve the controlled use of potentially harmful biological and/or chemical materials, and are subject to U.S., state, EU, national and
local  laws  and  regulations  governing  the  use,  storage,  handling  and  disposal  of  those  materials  and  specified  waste  products.  We  cannot  completely
eliminate the risk of accidental contamination or injury from the use, storage, handling or disposal of these materials, including fires and/or explosions,
storage  tank  leaks  and  ruptures  and  discharges  or  releases  of  toxic  or  hazardous  substances.  These  operating  risks  can  cause  personal  injury,  property
damage  and  environmental  contamination,  and  may  result  in  the  shutdown  of  affected  facilities  and  the  imposition  of  civil  or  criminal  penalties.  The
occurrence of any of these events may significantly reduce the productivity and profitability of a particular manufacturing facility and adversely affect our
operating results.

We  currently  maintain  property,  business  interruption  and  casualty  insurance  with  limits  that  we  believe  to  be  commercially  reasonable,  but  may  be
inadequate to cover any actual liability or damages.

Risks Related to Ownership of Our Securities

The price of ADSs representing our ordinary shares has been volatile and may continue to be volatile.

The trading price of American Depositary Shares representing our ordinary shares, or ADSs, has been, and is likely to continue to be, highly volatile. The
market value of an investment in ADSs may fall sharply at any time due to this volatility. During the year ended December 31, 2019, the closing sale price
of ADSs as reported on the Nasdaq Global Market ranged from $1.09 to $7.70. During the year ended December 31, 2018, the closing sale price of ADSs
as reported on the Nasdaq Global Market ranged

-30-

from $1.74 to $11.70. The market prices for securities of drug delivery, specialty pharma, biotechnology and pharmaceutical companies historically have
been highly volatile. Factors that could adversely affect our share price include, among others:

•
•
•
•
•
•
•
•

•
•
•
•
•
•

fluctuations in our operating results;
announcements of technological partnerships, innovations or new products by us or our competitors;
actions with respect to the acquisition of new or complementary businesses;
governmental regulations;
developments in patent or other proprietary rights owned by us or others;
public concern as to the safety of drug delivery technologies developed by us or drugs developed by others using our platform;
the results of pre-clinical testing and clinical studies or trials by us or our competitors;
adverse events related to our products or products developed by pharmaceutical and biotechnology company partners that use our drug delivery
technologies;
lack of efficacy of our products;
litigation;
decisions by our pharmaceutical and biotechnology company partners relating to the products incorporating our technologies;
the perception by the market of specialty pharma, biotechnology, and high technology companies generally;
general market conditions, including the impact of the current financial environment; and
the dilutive impact of any new equity or convertible debt securities we may issue or have issued.

We incurred a net loss in 2019 and we will likely incur a net loss in 2020, and if we are not able to regain profitability in the future, the value of our
shares may fall.

We reported a net loss of $33.2 million and $95.3 million for the years ended December 31, 2019 and 2018, respectively. In addition, in part because we
expect sales of our hospital products to suffer further substantial declines during 2020 and we will incur substantial expenses to develop our products, we
will likely incur a net loss in 2020 as well, the amount of which is not known to us at this time. We cannot predict if we will be able to regain profitability.
If we are unable to earn a profit in future periods, the market price of our shares may fall. Our ability to operate profitably depends upon a number of
factors, many of which are beyond our direct control. These factors include:

•
•
•
•
•
•
•
•
•

the demand for our drug delivery technologies and products;
the level of product and price competition;
our ability to develop new partnerships and additional commercial applications for our products;
our ability to control our costs;
our ability to broaden our customer base;
the effectiveness of our marketing strategy;
our effective tax rate;
the effectiveness of our partners’ marketing strategy for products that use our technology; and
general economic conditions.

We may require additional financing, which may not be available on favorable terms or at all, and which may result in dilution of the equity interest of
the holders of ADSs.

We  may  require  additional  financing  to  fund  the  development  and  possible  acquisition  of  new  products  and  businesses.  We  may  consume  available
resources more rapidly than currently anticipated, resulting in the need for additional funding. If we cannot obtain financing when needed, or obtain it on
favorable terms, we may be required to curtail our plans to continue to develop drug delivery technologies, develop new products, or acquire additional
products and businesses. Other factors that will affect future capital requirements and may require us to seek additional financing include:

•
•
•

the development and acquisition of new products and drug delivery technologies;
the progress of our research and product development programs; and
the timing of, and amounts received from, future product sales, product development fees and licensing revenue and royalties.

If  adequate  funds  are  not  available,  we  may  be  required  to  significantly  reduce  or  refocus  our  product  development  efforts,  resulting  in  loss  of  sales,
increased  costs  and  reduced  revenues.  Alternatively,  to  obtain  needed  funds  for  acquisitions  or  operations,  we  may  choose  to  issue  additional  ADSs
representing our ordinary shares, or issue equity-linked debt, or we may choose to issue preferred shares, in either case through public or private financings.
Additional funds may not be available on terms that are favorable to

-31-

us and, in the case of such equity financings, may result in dilution to the holders of ADSs. See also the discussion elsewhere in these Risk Factors under
the caption “Our net loss and the resulting decrease in our available liquid assets may limit our ability to fully pursue our business strategy.”

We have broad discretion in the use of our cash and may not use it effectively.

Our management has broad discretion in the use of our cash, and may not apply our cash in ways that ultimately increases the value of any investment in
our securities. We currently intend to use our cash to fund marketing activities for our commercialized products, to fund certain clinical trials for product
candidates, to fund R&D activities for potential new product candidates, and for working capital, capital expenditures and general corporate purposes. As
in  the  past  we  expect  to  invest  our  excess  cash  in  available-for-sale  marketable  securities,  including  corporate  bonds,  U.S.  government  securities,  other
fixed income securities and equities; and these investments may not yield a favorable return. If we do not invest or apply our cash effectively, our financial
position and the price of ADSs may decline.

We currently do not intend to pay dividends and cannot assure the holders of our ADSs that we will make dividend payments in the future.

We have never declared or paid a cash dividend on any of our ordinary shares or ADSs and do not anticipate declaring cash dividends in the foreseeable
future. Declaration of dividends will depend upon, among other things, future earnings, if any, the operating and financial condition of our business, our
capital requirements, general business conditions and such other factors as our Board of Directors deems relevant.

Provisions of our articles of association could delay or prevent a third-party’s effort to acquire us.

Our articles of association could delay, defer or prevent a third-party from acquiring us, even where such a transaction would be beneficial to the holders of
ADSs, or could otherwise adversely affect the price of ADSs. For example, certain provisions of our articles of association:

•
•
•

permit our board of directors to issue preferred shares with such rights and preferences as they may designate, subject to applicable law;
impose advance notice requirements for shareholder proposals and director nominations to be considered at annual shareholder meetings; and
require the approval of a supermajority of the voting power of our shares entitled to vote at a general meeting of shareholders to amend or repeal
any provisions of our articles of association.

We  believe  these  provisions,  if  implemented  in  compliance  with  applicable  law,  may  provide  some  protection  to  holders  of  ADSs  from  coercive  or
otherwise unfair takeover tactics. These provisions are not intended to make us immune from takeovers. They will, however, apply even if some holders of
ADSs  consider  an  offer  to  be  beneficial  and  could  delay  or  prevent  an  acquisition  that  our  Board  of  Directors  determines  is  in  the  best  interest  of  the
holders of ADSs. Certain of these provisions may also prevent or discourage attempts to remove and replace incumbent directors.

In  addition,  mandatory  provisions  of  Irish  law  could  prevent  or  delay  an  acquisition  of  the  Company  by  a  third  party.  For  example,  Irish  law  does  not
permit shareholders of an Irish public limited company to take action by written consent with less than unanimous consent. In addition, an effort to acquire
us  may  be  subject  to  various  provisions  of  Irish  law  relating  to  mandatory  bids,  voluntary  bids,  requirements  to  make  a  cash  offer  and  minimum  price
requirements, as well as substantial acquisition rules and rules requiring the disclosure of interests in ADSs in certain circumstances.

These provisions may discourage potential takeover attempts or bids for our ordinary shares at a premium over the market price or they may adversely
affect the market price of, and the voting and other rights of the holders of, ADSs. These provisions could also discourage proxy contests and make it more
difficult for holders of ADSs to elect directors other than the candidates nominated by our board of directors, and could depress affect the market price of
ADSs.

Irish law differs from the laws in effect in the U.S. and might afford less protection to the holders of ADSs.

Holders  of  ADSs  could  have  more  difficulty  protecting  their  interests  than  would  the  shareholders  of  a  U.S.  corporation.  As  an  Irish  company,  we  are
governed  by  Irish  law,  including  the  Irish  Companies  Act  2014  and  the  Irish  Takeover  Rules,  which  differs  in  some  significant,  and  possibly  material,
respects  from  provisions  set  forth  in  various  U.S.  state  laws  applicable  to  U.S.  corporations  and  their  shareholders,  including  provisions  relating  to
interested directors, mergers and acquisitions, takeovers, shareholder lawsuits and indemnification of directors.

-32-

The  duties  of  directors  and  officers  of  an  Irish  company  are  generally  owed  to  the  company  only.  Therefore,  under  Irish  law  shareholders  of  Irish
companies do not generally have a right to commence a legal action against directors or officers, and may only do so in limited circumstances. Directors of
an  Irish  company  must  act  with  due  care  and  skill,  honestly  and  in  good  faith  with  a  view  to  the  best  interests  of  the  company.  Directors  must  not  put
themselves in a position in which their duties to the company and their personal interests conflict and must disclose any personal interest in any contract or
arrangement with the company or any of our subsidiaries. A director or officer can be held personally liable to the company in respect of a breach of duty
to the company.

Judgments of U.S. courts, including those predicated on the civil liability provisions of the federal securities laws of the U.S., may not be enforceable in
Irish courts.

An investor in the U.S. may find it difficult to:

•
•

•

effect service of process within the U.S. against us and our non-U.S. resident directors and officers;
enforce  U.S.  court  judgments  based  upon  the  civil  liability  provisions  of  the  U.S.  federal  securities  laws  against  us  and  our  non-U.S.  resident
directors and officers in Ireland; or
bring  an  original  action  in  an  Irish  court  to  enforce  liabilities  based  upon  the  U.S.  federal  securities  laws  against  us  and  our  non-U.S.  resident
directors and officers.

Judgments  of  U.S.  courts,  including  those  predicated  on  the  civil  liability  provisions  of  the  federal  securities  laws  of  the  United  States,  may  not  be
enforceable in Cayman Islands courts.

We  have  been  advised  by  our  Cayman  Islands  legal  counsel,  Maples  and  Calder,  that  the  courts  of  the  Cayman  Islands  are  unlikely  (i)  to  recognize  or
enforce against us or Avadel judgments of courts of the U.S. predicated upon the civil liability provisions of the securities laws of the U.S. or any State; and
(ii)  in  original  actions  brought  in  the  Cayman  Islands,  to  impose  liabilities  against  us  or  Avadel  predicated  upon  the  civil  liability  provisions  of  the
securities laws of the U.S. or any State, so far as the liabilities imposed by those provisions are penal in nature. In those circumstances, although there is no
statutory  enforcement  in  the  Cayman  Islands  of  judgments  obtained  in  the  U.S.,  the  courts  of  the  Cayman  Islands  will  recognize  and  enforce  a  foreign
money judgment of a foreign court of competent jurisdiction without retrial on the merits based on the principle that a judgment of a competent foreign
court imposes upon the judgment debtor an obligation to pay the sum for which judgment has been given provided certain conditions are met. For a foreign
judgment to be enforced in the Cayman Islands, such judgment must be final and conclusive and for a liquidated sum, and must not be in respect of taxes or
a fine or penalty, inconsistent with a Cayman Islands judgment in respect of the same matter, impeachable on the grounds of fraud or obtained in a manner,
and  or  be  of  a  kind  the  enforcement  of  which  is,  contrary  to  natural  justice  or  the  public  policy  of  the  Cayman  Islands  (awards  of  punitive  or  multiple
damages may well be held to be contrary to public policy). A Cayman Islands Court may stay enforcement proceedings if concurrent proceedings are being
brought elsewhere.

Holders of ADSs have fewer rights than shareholders and have to act through the Depositary to exercise those rights.

Holders of ADSs do not have the same rights as shareholders and, accordingly, cannot exercise rights of shareholders against us. The Bank of New York
Mellon,  as  depositary,  or  the  “Depositary”,  is  the  registered  shareholder  of  the  deposited  shares  underlying  the  ADSs.  Therefore,  holders  of  ADSs  will
generally have to exercise the rights attached to those shares through the Depositary. We will use reasonable efforts to request that the Depositary notify the
holders of ADSs of upcoming votes and ask for voting instructions from them. If a holder fails to return a voting instruction card to the Depositary by the
date established by the Depositary for receipt of such voting instructions, or if the Depositary receives an improperly completed or blank voting instruction
card, or if the voting instructions included in the voting instruction card are illegible or unclear, then such holder will be deemed to have instructed the
Depositary to vote its shares, and the Depositary shall vote such shares in favor of any resolution proposed or approved by our Board of Directors and
against any resolution not so proposed or approved.

Our largest shareholders own a significant percentage of the share capital and voting rights of the Company.

As of February 25, 2020, RTW Investments LP. owned approximately 10.0% of Avadel’s outstanding shares (in the form of ADSs), Avoro Capital Advisors
LLC  owned  approximately  8.4%  of  our  outstanding  shares  (in  the  form  of  ADSs)  and  Vivo  Opportunity,  LLC  and  certain  of  its  affiliates  owned
approximately 7.6% of our outstanding shares (in the form of ADSs). To the extent these shareholders continue to hold a large percentage of our share
capital and voting rights, they will remain in a position to exert heightened influence in the election of the directors of the Company and in other corporate
actions that require shareholder approval, including change of control transactions.

-33-

U.S. Holders of ordinary shares or ADSs may suffer adverse U.S. tax consequences if we are classified as a passive foreign investment company.

Generally, if, for any taxable year, at least 75% of our gross income is passive income, or at least 50% of the value of our assets is attributable to assets that
produce  passive  income  or  are  held  for  the  production  of  passive  income,  including  cash,  we  would  be  characterized  as  a  passive  foreign  investment
company, or PFIC, for U.S. federal income tax purposes. For purposes of these tests, passive income includes dividends, interest, and gains from the sale or
exchange of investment property and rents and royalties other than rents and royalties that are received from unrelated parties in connection with the active
conduct of a trade or business. Our status as a PFIC depends on the composition of our income and the composition and value of our assets (for which
purpose the total value of our assets may be determined in part by the market value of the ordinary shares or ADSs, which are subject to change) from time
to time. If we are characterized as a PFIC, U.S. Holders (as defined below under “Material U.S. Federal Income Tax Considerations for U.S. Holders”) of
ordinary shares or ADSs may suffer materially adverse tax consequences, including having gains realized on the sale of ordinary shares or ADSs treated as
ordinary income, rather than capital gain, the loss of the preferential rate applicable to dividends received on ordinary shares or ADSs by individuals who
are U.S. Holders, and having interest charges apply to distributions by us and the proceeds of sales of ordinary shares or ADSs. See “Material U.S. Federal
Income Tax Considerations for U.S. Holders—PFIC rules.”

We believe that we were not a PFIC for the taxable year ending December 31, 2019 and, based on the expected value of our assets, including any goodwill,
and the expected nature and composition of our income and assets, we do not anticipate that we will be a PFIC for our current taxable year. However, our
status as a PFIC is a fact-intensive determination subject to various uncertainties, and we cannot provide any assurances regarding our PFIC status for the
current, prior or future taxable years.

Certain U.S. Holders that own 10 percent or more of the vote or value of ordinary shares or ADSs may suffer adverse U.S. tax consequences because
our non-U.S. subsidiaries are expected to be classified as controlled foreign corporations.

Each ‘‘Ten Percent Shareholder’’ (as defined below) in a non-U.S. corporation that is classified as a ‘‘controlled foreign corporation,’’ or a CFC, for U.S.
federal income tax purposes generally is required to include in income for U.S. federal tax purposes such Ten Percent Shareholder’s pro rata share of the
CFC’s ‘‘Subpart F income’’ and investment of earnings in U.S. property, even if the CFC has made no distributions to its shareholders. Subpart F income
generally  includes  dividends,  interest,  rents,  royalties,  ‘‘global  intangible  low-taxed  income,’’  gains  from  the  sale  of  securities  and  income  from  certain
transactions with related parties. In addition, a Ten Percent Shareholder that realizes gain from the sale or exchange of shares in a CFC may be required to
classify a portion of such gain as dividend income rather than capital gain. A non-U.S. corporation generally will be classified as a CFC for U.S. federal
income tax purposes if Ten Percent Shareholders own, directly or indirectly, more than 50% of either the total combined voting power of all classes of
stock of such corporation entitled to vote or of the total value of the stock of such corporation. A ‘‘Ten Percent Shareholder’’ is a U.S. person (as defined by
the Code) who owns or is considered to own 10% or more of the total combined voting power of all classes of stock entitled to vote or 10% or more of the
total value of all classes of stock of such corporation.

We believe that we were not a CFC in the 2019 taxable year, but that our non-U.S. subsidiaries were CFCs in the 2019 taxable year. We anticipate that our
non-U.S. subsidiaries will remain CFCs in the 2020 taxable year, and it is possible that we may become a CFC in the 2020 taxable year or in a subsequent
taxable  year.  The  determination  of  CFC  status  is  complex  and  includes  attribution  rules,  the  application  of  which  is  not  entirely  certain.  U.S.  Holders
should  consult  their  own  tax  advisors  with  respect  to  the  potential  adverse  U.S.  tax  consequences  of  becoming  a  Ten  Percent  Shareholder  in  a  CFC,
including the possibility and consequences of becoming a Ten Percent Shareholder in one or more of our non-U.S. subsidiaries that are anticipated to be
treated as CFCs. If we are classified as both a CFC and a PFIC, we generally will not be treated as a PFIC with respect to those U.S. Holders that meet the
definition of a Ten Percent Shareholder during the period in which we are a CFC, subject to certain exceptions.

A transfer of ordinary shares may be subject to Irish stamp duty.

Transfers of ordinary shares (as opposed to ADSs) could be subject to Irish stamp duty (currently at the rate of 1% of the higher of the price paid or the
market  value  of  the  shares  acquired).  Payment  of  Irish  stamp  duty  is  generally  a  legal  obligation  of  the  transferee.  Although  transfers  of  ADSs  are  not
subject to Irish stamp duty, the potential for stamp duty to arise on transfers of ordinary shares could adversely affect the price of our ordinary shares or
ADSs.

Risks Related to the 2023 Notes

Servicing our 2023 Notes may require a significant amount of cash, and we may not have sufficient cash or the ability to raise the funds necessary to
settle exchanges of the 2023 Notes in cash, repay the Notes at maturity, or repurchase the 2023 Notes as required following a fundamental change.

In February 2018 we issued $143.75 million aggregate principal amount of our Senior Exchangeable Notes. Prior to February 2023, the 2023 Notes are
convertible  at  the  option  of  the  holders  only  under  certain  conditions  or  upon  the  occurrence  of  certain  events.  If  holders  of  the  2023  Notes  elect  to
exchange their 2023 Notes, unless we elect to deliver solely our ADSs to settle such exchanges, we will be required to make cash payments in respect of
the 2023 Notes being exchanged. Holders of the 2023 Notes also have the right to require us to repurchase all or a portion of their 2023 Notes upon the
occurrence of a fundamental change (as defined in the applicable indenture governing the 2023 Notes) at a repurchase price equal to 100% of the principal
amount of the 2023 Notes to be repurchased, plus accrued and unpaid interest. If the 2023 Notes have not previously been exchanged or repurchased, we
will  be  required  to  repay  the  2023  Notes  in  cash  at  maturity.  Our  ability  to  make  cash  payments  in  connection  with  exchanges  of  the  2023  Notes,
repurchase the 2023 Notes in the event of a fundamental change, or to repay or refinance the 2023 Notes at maturity will depend on market conditions and
our  future  performance,  which  is  subject  to  economic,  financial,  competitive,  and  other  factors  many  of  which  are  beyond  our  control.  We  incurred
significant net losses in 2019 and we may continue to incur significant losses. As a result, we may not have enough available cash or be able to obtain
financing  at  the  time  we  are  required  to  repurchase  or  repay  the  2023  Notes  or  in  the  event  we  elect  to  pay  cash  with  respect  to  2023  Notes  being
exchanged.

The conditional exchange feature of the 2023 Notes, if triggered, may adversely affect our financial condition and operating results.

In the event the conditional exchange feature of the 2023 Notes is triggered, holders of 2023 Notes will be entitled to exchange the 2023 Notes at any time
during specified periods at their option (see the discussion under the caption “Recent Developments -- Issuance of Exchangeable Notes” in Item 1 of this
Annual Report on Form 10-K). If one or more holders elect to exchange their 2023 Notes, unless we elect to satisfy our exchange obligation by causing to
be delivered solely ADSs (other than paying cash in lieu of any fractional ADSs), we would be required to settle a portion or all of our exchange obligation
through the payment of cash, which could adversely affect our liquidity. In addition, even if holders do not elect to exchange their 2023 Notes, we could be
required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the 2023 Notes as a current rather than long-term
liability, which would result in a material reduction of our net working capital.

The accounting method for convertible and exchangeable debt securities that may be settled in cash, such as the 2023 Notes, could have a material
effect on our reported financial results.

Under Accounting Standards Codification 470-20, Debt with Conversion and Other Options, which we refer to as ASC 470-20, an entity must separately
account for the liability and equity components of the convertible or exchangeable debt instruments (such as the 2023 Notes) that may be settled entirely or
partially  in  cash  upon  conversion  or  exchange  in  a  manner  that  reflects  the  issuer’s  economic  interest  cost.  However,  entities  must  first  consider  the
guidance in ASC 815-15, Embedded Derivatives (“ASC 815-15”), to determine if an instrument contains an embedded feature that should be separately
accounted for as a derivative. ASC 815 provides for an exception to this rule when convertible notes, as host instruments, are deemed to be conventional, as
defined by ASC 815-40. Should this exception apply, the effect of ASC 470-20 on the accounting for the 2023 Notes is that the equity component would be
required to be included in the additional paid-in capital section of shareholders’ equity on Avadel’s consolidated balance sheet, and the value of the equity
component would be treated as original issue discount for purposes of accounting for the debt component of the 2023 Notes. As a result, Avadel would be
required to record a greater amount of non-cash interest expense in current periods presented as a result of the amortization of the discounted carrying value
of the 2023 Notes to their face amount over the term of the 2023 Notes. Avadel would report lower net income in its financial results because ASC 470-20
would require interest to include both the current period’s amortization of the debt discount and the instrument’s coupon interest, which could adversely
affect Avadel’s reported or future financial results, the trading price of the ADSs and the trading price of the 2023 Notes.

In addition, under certain circumstances, convertible or exchangeable debt instruments (such as the 2023 Notes) that may be settled entirely or partly in
cash are currently accounted for utilizing the treasury stock method, the effect of which is that the ADSs deliverable upon exchange of the 2023 Notes are
not included in the calculation of diluted earnings per share except to the extent that the exchange value of the 2023 Notes exceeds their principal amount.
Under the treasury stock method, for diluted earnings per share purposes, the transaction is accounted for as if the number of ADSs that would be necessary
to settle such excess, if we elected to settle such excess in ADSs, are issued. We cannot be sure that the accounting standards in the future will continue to

-35-

permit the use of the treasury stock method. If Avadel is unable to use the treasury stock method in accounting for the ADSs deliverable upon exchange of
the 2023 Notes, then Avadel’s diluted earnings per share would be adversely affected.

Exchanges of the 2023 Notes will dilute the ownership interest of Avadel’s existing shareholders and holders of the ADSs, including holders who had
previously exchanged their 2023 Notes and received ADSs upon exchange, to the extent our exchange obligation includes ADSs.

The exchange of some or all of the 2023 Notes will dilute the ownership interests of Avadel’s existing shareholders and holders of the ADSs to the extent
our exchange obligation includes ADSs. Any sales in the public market of the ADSs issuable upon such exchange of the 2023 Notes could adversely affect
prevailing market prices of the ADSs and, in turn, the price of the 2023 Notes. In addition, the existence of the 2023 Notes may encourage short selling by
market participants because the exchange of the 2023 Notes could depress the price of the ADSs.

The fundamental change repurchase feature of the 2023 Notes may delay or prevent an otherwise beneficial takeover attempt of Avadel.

The indenture governing the 2023 Notes will require us to repurchase the 2023 Notes for cash upon the occurrence of a fundamental change and, in certain
circumstances, to increase the exchange rate for a holder that exchanges its 2023 Notes in connection with a make-whole fundamental change. A takeover
of Avadel may trigger the requirement that we repurchase the 2023 Notes and/or increase the exchange rate, which could make it more costly for a potential
acquirer to engage in a combinatory transaction with us or Avadel. Such additional costs may have the effect of delaying or preventing a takeover of Avadel
that would otherwise be beneficial to investors.

Dividends paid by the Parent may be subject to Irish dividend withholding tax

In certain circumstances, as an Irish tax resident company, Avadel will be required to deduct Irish dividend withholding tax (currently at the rate of 20%)
from dividends paid to its shareholders. Shareholders that are resident in the U.S., EU countries (other than Ireland) or other countries with which Ireland
has signed a tax treaty (whether the treaty has been ratified or not) generally should not be subject to Irish withholding tax so long as the shareholder has
provided  its  broker,  for  onward  transmission  to  Avadel’s  qualifying  intermediary  or  other  designated  agent  (in  the  case  of  shares  held  beneficially),  or
Avadel or its transfer agent (in the case of shares held directly), with all the necessary documentation by the appropriate due date prior to payment of the
dividend. However, some shareholders may be subject to withholding tax, which could adversely affect the price of ordinary shares and the value of their
2023 Notes.

Item 2.        Properties.

(Amounts in thousands, except square foot amounts)

We have commercial and administrative activities located in Chesterfield, Missouri. Our current office space consists of 24,236 square feet, and the lease
expires in 2025. Additionally, we still maintain the lease on the former headquarters of FSC Laboratories, Inc. located in Charlotte, North Carolina. This
office space consists of 6,300 square feet, and the lease expires in 2020.

Avadel  Research  SAS,  our  prior  research  center,  was  located  in  Venissieux,  France  (a  suburb  of  Lyon)  in  two  adjacent  leased  facilities  totaling
approximately  25,600  square  feet.    One  building  of  approximately  12,800  square  feet  housed  the  administrative  offices  and  analytical  research
laboratories.  A second facility comprising approximately 12,800 square feet housed equipment dedicated to our Micropump and LiquiTime platforms. 
Both leases were terminated during the three months ended December 31, 2019 as part of the 2019 French Restructuring plan. See Note 18: Restructuring
Costs in Part II, item 8 of this Annual Report on Form 10-K for more information.

We had intellectual property, clinical, quality, regulatory, and supply chain activities located in Dublin, Ireland. The office space consisted of 5,059 square
feet  and  the  lease  expired  in  2025.  This  lease  was  surrendered  during  the  three  months  ended  December  31,  2019  as  part  of  the  2019  Corporate
Restructuring plan. See Note 18: Restructuring Costs in Part II, item 8 of this Annual Report on Form 10-K for more information.

Item 3.        Legal Proceedings.

Voluntary Chapter 11 Bankruptcy Filing by Specialty Pharma update

Note 3: Subsidiary Bankruptcy and Deconsolidation on Part II, item 8 of this annual report on From 10-K briefly describes the Chapter 11 bankruptcy case
which our subsidiary Specialty Pharma commenced on February 6, 2019, and which on April 26, 2019 resulted in the bankruptcy court-approved sale of all
of Specialty Pharma’s intangible assets and inventory to an unaffiliated third party. As a result of such sale, Specialty Pharma has completed its divestment
of the assets of the Noctiva business. During the pendency of the bankruptcy case, all pending litigation against Specialty Pharma is automatically stayed
and any new litigation against Specialty Pharma is precluded unless the bankruptcy court orders otherwise. Below are descriptions of a litigation to which
Specialty  Pharma  is  a  party  and  a  contract  dispute  involving  Specialty  Pharma,  both  of  which  matters  are  subject  to  the  automatic  stay  during  the
bankruptcy case.

Ferring  Litigation.  Some  of  the  patents  covering  the  Noctiva  product  (the  “Noctiva  Patents”)  are  the  subject  of  litigation  initiated  by  Ferring
Pharmaceuticals Inc. and two of its foreign affiliates, who manufacture a competing product known as Nocdurna.  Nocdurna was approved by the FDA in
June 2018 and commercially launched in the U.S. in November 2018.  In this litigation, filed in the United States District Court for the Southern District of
New York, Ferring seeks to invalidate and disputes the inventorship of the Noctiva Patents, seeks damages for various alleged breaches of contractual and
common  law  duties,  and  seeks  damages  for  alleged  infringement  by  Noctiva  of  Ferring’s  “Nocdurna”  trademark.    Specialty  Pharma  and  certain  other
parties  including  Serenity  Pharmaceuticals,  LLC  (“Serenity”)  (the  licensor  of  the  Noctiva  Patents)  have  defended  this  litigation,  and  have  made
counterclaims against Ferring, including for infringement of the Noctiva Patents and a declaratory judgment of noninfringement with respect to Ferring’s
“Nocdurna”  trademark.  The  court  dismissed  Ferring’s  inventorship  claim  and  its  claims  for  alleged  breaches  of  contractual  and  common  law  duties,
although these dismissals may be appealed by Ferring.  On February 15, 2019, Specialty Pharma and its co-defendants moved to stay the litigation pending
completion of the bankruptcy proceeding of Specialty Pharma. On May 15, 2019, that motion was denied due to a pending settlement of the litigation with
respect  to  just  Ferring  and  Specialty  Pharma.  On  February  25,  2020,  Ferring  and  Specialty  Pharma  jointly  moved  for  bankruptcy  court  approval  of  a
settlement agreement with respect to the claims alleged in the litigation.  In accordance with the terms of the settlement agreement, promptly following
bankruptcy court approval of the settlement agreement, the parties would dismiss with prejudice their respective claims against each other in the litigation. 
On March 13th, 2020, the bankruptcy court entered an order approving the settlement with Ferring.  Pursuant to the terms of the settlement, the parties are
to  dismiss  their  respective  claims  against  each  other  in  the  District  Court  litigation  in  the  Southern  District  of  New  York,  with  such  dismissals  to  be
effective concurrently.  That joint dismissal has not yet been filed with District Court for the Southern District of New York.

Contract Dispute. On January 21, 2019, Serenity gave notice to Specialty Pharma of an alleged breach of the parties’ Noctiva license agreement. Serenity
alleges that Specialty Pharma breached its contractual obligation to devote commercially reasonable efforts to the commercialization of Noctiva and seeks
unspecified damages. On January 27, 2019, Specialty Pharma notified Serenity of a claim for $1.7 million in damages as a result of Serenity’s breach of its
contractual  obligation  to  pay  the  costs  of  the  Ferring  Litigation.  Serenity’s  notice  to  Specialty  Pharma  invoked  the  dispute  resolution  provisions  of  the
Noctiva license agreement, which culminate in arbitration, but neither party has yet initiated an arbitration proceeding or filed suit.

Exela Litigation.  On January 7, 2020, Exela filed a complaint against us and our subsidiary, Avadel Legacy in the United States District for the District of
Delaware. The complaint alleges infringement of a certain Exela patent related to its cysteine hydrochloride product. Exela is most notably seeking i) a
declaratory judgment that the Nouress product infringes its patent, ii) an injunction (both preliminary and permanent) precluding the launch of Nouress, and
iii) monetary damages (including enhanced damages, prejudgment interest and attorneys’ fees) in the event Nouress is commercially launched and found to
infringe Exela’s patent.  We have not yet been served with the complaint.

Item 5.

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

Common Stock Data (per share):

The principal trading market for our securities in ADSs is the Nasdaq Global Market under the symbol “AVDL”. There is no foreign trading market for our
ordinary shares, ADSs or any other equity security issued by us. Each ADS represents one ordinary share, nominal value $0.01. Each ADS is evidenced by
an ADR. The Bank of New York Mellon is the Depositary for the ADRs.

As of March 10, 2020, there were 46,404,432 ordinary shares outstanding, and our closing stock price was $8.57 per share.

The following table reports the high and low trading prices of the ADSs on the Nasdaq Global Market for the periods indicated:

As  of  March  10,  2020,  there  were  79  holders  of  record  of  our  ordinary  shares  and  42  accounts  registered  with  The  Bank  of  New  York  Mellon,  the
depositary of our ADS program, as holders of ADSs, one of which ADS accounts is registered to the Depositary Trust Corporation (DTC). Because our
ADSs are generally held of record by brokers, nominees and other institutions as participants in DTC on behalf of the beneficial owners of such ADSs, we
are unable to estimate the total number of beneficial owners of the ADSs held by these record holders.

Dividends

We have never declared or paid a cash dividend on any of our shares and do not anticipate declaring cash dividends in the foreseeable future.

Equity Compensation Plan

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

Share Performance Graph

The  following  graph  compares  the  cumulative  5-year  return  provided  to  shareholders  of  Avadel’s  ADSs  relative  to  the  cumulative  total  returns  of  the
Nasdaq  Composite  Index  and  the  Nasdaq  Biotechnology  Index.  We  believe  these  indices  are  the  most  appropriate  indices  against  which  the  total
shareholder return of Avadel should be measured. The Nasdaq Biotechnology Index has been selected because it is an index of U.S. quoted biotechnology
and pharmaceutical companies. An investment of $100 (with reinvestment of all dividends) is assumed to have been made in our ADSs and in each of the
indexes  on  January  1,  2013  and  our  relative  performance  is  tracked  through  December  31,  2019.  The  comparisons  shown  in  the  graph  are  based  upon
historical  data  and  we  caution  that  the  stock  price  performance  shown  in  the  graph  is  not  indicative  of,  or  intended  to  forecast,  the  potential  future
performance of our stock.

This performance graph shall not be deemed “filed” for purposes of Section 18 of the Exchange Act. Notwithstanding any statement to the contrary set
forth in any of our filings under the Securities Act of 1933 or the Exchange Act that might incorporate future filings, including this Annual Report on Form

Information pertaining to fiscal year 2017 was included in the Company’s Annual Report on Form 10-K for the year-ended December 31, 2018, on pages
42 through 58, under Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” which was filed with the
SEC on March 15, 2019.

Overview 

Nature of Operations

Avadel  Pharmaceuticals  plc  (Nasdaq:  AVDL)  (“Avadel,”  the  “Company,”  “we,”  “our,”  or  “us”)  is  an  emerging  biopharmaceutical  company.  Our  lead
product candidate, FT218, is an investigational once-nightly formulation of sodium oxybate for the treatment of excessive daytime sleepiness (“EDS”), and
cataplexy in narcolepsy patients. FT218, which uses our Micropump drug-delivery technology, is in a Phase 3 clinical trial for the treatment of narcolepsy
patients suffering from EDS and cataplexy. In addition, we have three approved commercial products developed under our “unapproved marketed drug,” or
UMD, program, Akovaz, Bloxiverz and Vazculep, and a fourth approved product, Nouress, which are sterile injectable drugs used in the hospital setting.

We are primarily focused on the development and potential U.S. Food and Drug Administration (“FDA”) approval of FT218. In addition, we continue to
market  and  distribute  our  current  approved  hospital  products  portfolio  and,  pending  resolution  of  the  existing  patent  infringement  claim  (as  described
below), we plan to commercialize Nouress. Outside of our product candidate and our existing commercial products, we continue to evaluate opportunities
to expand our product portfolio.

FT218 (Micropump sodium oxybate)

FT218 is a once-nightly formulation of sodium oxybate that uses our Micropump controlled release drug-delivery technology for the treatment of EDS and
cataplexy in patients suffering from narcolepsy. Sodium oxybate is the sodium salt of gamma hydroxybutyrate, an endogenous compound and metabolite of
the  neurotransmitter  gamma-aminobutyric  acid.  Sodium  oxybate  is  approved  in  Europe  and  the  United  States  (“U.S.”)  as  a  twice-nightly  formulation
indicated for the treatment of EDS and cataplexy in patients with narcolepsy.

In December 2019, we completed patient enrollment of our Phase 3 REST-ON clinical trial of FT218 to assess the safety and efficacy of a once-nightly
formulation of FT218 for the treatment of EDS and cataplexy in patients suffering from narcolepsy. The REST-ON trial is a randomized, double-blind,
placebo-controlled study that has enrolled 212 patients and is being conducted in clinical sites in the U.S., Canada, Western Europe and Australia. Top line
data from the REST-ON trial is currently expected in the second quarter of 2020.

In January 2018, the FDA granted FT218 Orphan Drug Designation, which makes the drug eligible for certain development and commercial incentives,
including a potential U.S. market exclusivity for up to seven years. Additionally, in April 2019, our first FT218 patent was issued, providing intellectual
property protection into 2037. There are additional patent applications currently in development and/or pending at the USPTO, as well as foreign patent
offices.

We believe FT218 has the potential to demonstrate improved dosing compliance, safety and patient satisfaction over the current standard of care for EDS
and cataplexy in patients with narcolepsy, which is a twice-nightly sodium oxybate formulation. If

-42-

approved,  we  believe  FT218  has  the  potential  to  take  a  significant  share  of  the  sodium  oxybate  market.  The  current  market  size  for  the  twice-nightly
administration of sodium oxybate is estimated at an annualized revenue run rate of $1.7 billion.

Micropump Drug-Delivery Technology

Our Micropump drug-delivery technology allows for the delayed delivery of small molecule drugs taken orally, which has the potential to improve dosing
compliance, reduce toxicity and improve patient compliance. Beyond FT218, we believe there could be other product development opportunities for our
Micropump  drug  delivery  technology,  representing  either  “life  cycle”  opportunities,  whereby  additional  intellectual  property  can  be  added  to  a
pharmaceutical  product  to  extend  the  commercial  viability  of  a  currently  marketed  product,  or  innovative  formulation  opportunities  for  new  chemical
entities.

Unapproved Marketed Drugs Program

The  FDA  allows  certain  unapproved  prescription  drugs  to  be  marketed  if  (i)  they  are  relied  on  by  health  care  professionals  to  treat  serious  medical
conditions, and (ii) there is no FDA-approved drug to treat such condition or insufficient supply of FDA-approved drugs. In most cases, these prescription
drugs pre-date the establishment of the FDA. Although these products are typically not protected by patents or similar intellectual property, FDA guidance
states that, if it approves an NDA for any such products via a 505(b)(2) process, the FDA is more likely to seek enforcement action, such as seizure or
injunction, against remaining unapproved drugs of the same type, potentially after a grace period provided by the FDA.

Existing Commercial Products

To date, we have received FDA approvals for three previously unapproved prescription drugs:

Bloxiverz (neostigmine methylsulfate injection) - Bloxiverz was approved by the FDA in May 2013 and was launched in July 2013. Bloxiverz
is a drug used intravenously in the operating room to reverse the effects of non-depolarizing neuromuscular blocking agents after surgery.
Bloxiverz was the first FDA-approved version of neostigmine methylsulfate. Today, neostigmine is one of the two most frequently used
products for the reversal of the effects of other agents used for neuromuscular blocks.

Vazculep  (phenylephrine  hydrochloride  injection)  -  Vazculep  was  approved  by  the  FDA  in  June  2014  and  was  launched  in  October  2014.
Vazculep is indicated for the treatment of clinically important hypotension occurring in the setting of anesthesia.

Akovaz (ephedrine sulfate injection). Akovaz, was approved by the FDA in April 2016 and was launched in August 2016. Akovaz was the first
FDA  approved  formulation  of  ephedrine  sulfate,  an  alpha-  and  beta-  adrenergic  agonist  and  a  norepinephrine-releasing  agent  that  is
indicated for the treatment of clinically important hypotension occurring in the setting of anesthesia.

Nouress

In December 2019, we received FDA approval for Nouress (cysteine hydrochloride injection), a sterile injectable product for use in the hospital setting, and
currently have two patents covering that product. Several additional patent applications for Nouress are pending with the USPTO. In light of the recently
filed patent suit by Exela Pharma Sciences, LLC, (“Exela”) we are currently evaluating the timing and process for a commercial launch of Nouress in the
U.S. See Note 16: Contingent Liabilities and Commitments for a discussion on the filed patent suit by Exela Pharma Sciences, LLC.

We  use  the  revenue  from  our  UMD  products  to  fund  the  research  and  development  of  FT218.  In  addition,  we  believe  evaluating  opportunities  to
commercialize other unapproved drugs in markets with a limited number of competitors may provide us with near-term revenue growth and potentially
provide cash flows that can also be used to fund research and development initiatives for the development of FT218 and other potential product candidates.

Corporate Information

We were incorporated on December 1, 2015 as an Irish private limited company, and re-registered as an Irish public limited company (“plc”), on November
21, 2016. Our principal place of business is located at 10 Earlsfort Terrace, Dublin 2, Ireland and our phone number is 00 353 1 920 1000. We file annual,

References  in  these  consolidated  financial  statements  and  the  notes  thereto  to  “Avadel,”  the  “Company,”  “we,”  “our,”  “us,”  and  similar  terms  shall  be
deemed to be references to Flamel prior to the completion of the Merger, unless the context otherwise requires.

Key Business Trends and Highlights 

In operating our business and monitoring our performance, we consider a number of performance measures, as well as trends affecting our industry as a
whole, which include the following: 

• Healthcare  and  Regulatory  Reform:  Various  health  care  reform  laws  in  the  U.S.  may  impact  our  ability  to  successfully  commercialize  our
products and technologies. The success of our commercialization efforts may depend on the extent to which the government health administration
authorities, the health insurance funds in the E.U. Member States, private health insurers and other third-party payers in the U.S. will reimburse
consumers for the cost of healthcare products and services.

•

•

Competition and Technological Change: Competition in the pharmaceutical and biotechnology industry continues to be intense and is expected
to increase. We compete with academic laboratories, research institutions, universities, joint ventures, and other pharmaceutical and biotechnology
companies,  including  other  companies  developing  niche  branded  or  generic  specialty  pharmaceutical  products  or  drug  delivery  platforms.
Furthermore,  major  technological  changes  can  happen  quickly  in  the  pharmaceutical  and  biotechnology  industries.  Such  rapid  technological
change, or the development by our competitors of technologically improved or differentiated products, could render our drug delivery platforms
obsolete or noncompetitive.

Pricing Environment for Pharmaceuticals: The pricing environment continues to be in the political spotlight in the U.S. As a result, the need to
obtain and maintain appropriate pricing for our products may become more challenging due to, among other things, the attention being paid to
healthcare cost containment and other austerity measures in the U.S. and worldwide.

• Generics Playing a Larger Role in Healthcare: Generic pharmaceutical products will continue to play a large role in the U.S. healthcare system.
Specifically, we have seen, or likely will see, additional generic competition to our current and future products and we continue to expect generic
competition in the future.

•

•

Access to and Cost of Capital: The process of raising capital and associated cost of such capital for a company of our financial profile can be
difficult and potentially expensive. If the need were to arise to raise additional capital, access to that capital may be difficult and/or expensive and,
as a result, could create liquidity challenges for us.

Possible Net Loss from Operations in 2020: In part because we expect sales of our hospital products to significantly decline from 2019 and we
will incur substantial expenses to further the clinical development of FT218, we likely will incur a net loss in 2020.

Recent Developments

Shelf Registration Statement on Form S-3

-44-

In February 2020, we filed with the SEC a new shelf registration statement on Form S-3 (the 2020 Shelf Registration Statement) (File No. 333-236258)
that allows issuance and sale by us, from time to time, of:

(a) up to $250,000 in aggregate of ordinary shares, nominal value US$0.01 per share (the “Ordinary Shares”), each of which may be represented by
ADSs, preferred shares, nominal value US$0.01 per share (the “Preferred Shares”), debt securities (the “Debt Securities”), warrants to purchase
Ordinary Shares, ADSs, Preferred Shares and/or Debt Securities (the “Warrants”), and/or units consisting of Ordinary Shares, ADSs, Preferred
Shares, one or more Debt Securities or Warrants in one or more series, in any combination, pursuant to the terms of the 2020 Shelf Registration
Statement, the base prospectus contained in the 2020 Shelf Registration Statement (the “Base Prospectus”), and any amendments or supplements
thereto (together, the “Securities”); including

(b) up to $50,000 of ADSs that may be issued and sold from time to time pursuant to the terms of an Open Market Sale AgreementSM (“the Sales
Agreement”),  entered  into  with  Jefferies  LLC  on  February  4,  2020  (the  “Sales  Agreement”),  the  2020  Shelf  Registration  Statement,  the  Base
Prospectus and the terms of the sales agreement prospectus contained in the 2020 Shelf Registration Statement.

Securities Purchase Agreement

On  February  21,  2020,  we  announced  that  we  have  entered  into  a  definitive  agreement  for  the  sale  of  our  ADSs  and  Series  A  Non-Voting  Convertible
Preferred Shares (“Series A Preferred”) in a private placement to a group of institutional accredited investors. The private placement has resulted in gross
proceeds of approximately $65,000 before deducting placement agent and other offering expenses, and resulting in net proceeds of approximately $61,000.

Pursuant to the terms of the private placement, we issued 8,680 ADSs and 488 shares of Series A Preferred at a price of $7.09 per share, priced at-the-
market under Nasdaq rules. Each share of non-voting Series A Preferred is convertible into one ADS, provided that conversion will be prohibited if, as a
result,  the  holder  and  its  affiliates  would  own  more  than  9.99%  of  the  total  number  of  Avadel  ADSs  outstanding.  The  closing  of  the  private  placement
occurred on February 25, 2020. Proceeds from the private placement will be used to fund continued clinical and program development of FT218, including
an open-label extension study for REST-ON, a switch study to evaluate patients switching from twice-nightly sodium oxybate to once-nightly FT218, as
well as for general corporate purposes.

Financial Highlights

Highlights of our consolidated results for the year ended December 31, 2019 are as follows: 

•

•

•

•

•

Revenue was $59,215 for the year ended December 31, 2019 compared to $103,269 in the same period last year. This year over year decrease was
primarily the result of increased competition driving lower prices as noted above in our discussion of Key  Business  Trends  and  Highlights. We
experienced price and unit volume declines across all our hospital products due to additional competition.

Operating loss was $24,112 for the year ended December 31, 2019 compared to an operating loss of $104,926 for the year ended December 31,
2018. The primary reasons for the decrease in operating loss was due to the 2018 impairment of the Noctiva intangible asset of $66,087 and lower
SG&A and R&D expenses in the current period of $70,176 and $6,412, respectively, primarily driven by the exit of Noctiva. These decreases were
partially offset by lower total revenues of $44,054 as discussed above and a decrease of $23,576 in the gain in fair value of related party contingent
consideration recognized during the year ended December 31, 2018 of $22,731 compared to expense of $845 recognized during the current year.

Net loss was $33,226 for the year ended December 31, 2019 compared to net loss of $95,304 in the same period last year.

Diluted net loss per share was $0.89 for the year ended December 31, 2019 compared to diluted net loss per share of $2.55 in the same period last
year.

Cash  and  marketable  securities  decreased  $35,757  to  $64,158  at  December  31,  2019  from  $99,915  at  December  31,  2018.  This  decrease  was
largely driven from $38,325 use of cash in operations.

Critical Accounting Estimates

The  preparation  of  consolidated  financial  statements  in  conformity  with  U.S.  GAAP  requires  management  to  use  judgment  in  making  estimates  and
assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the consolidated financial
statements and the reported amounts of revenues and expenses during the periods presented. Actual results could differ from those estimates under different
assumptions or conditions. 

The  following  accounting  policies  are  based  on,  among  other  things,  judgments  and  assumptions  made  by  management  that  include  inherent  risks  and
uncertainties. Management’s estimates are based on the relevant information available at the end of each period.

Revenue.  Revenue  includes  sales  of  pharmaceutical  products,  licensing  fees,  and,  if  any,  milestone  payments  for  research  and  development  (“R&D”)
achievements.

Product Sales  

We  sell  products  primarily  through  wholesalers  and  considers  these  wholesalers  to  be  its  customers.  Under  ASC  606,  revenue  from  product  sales  is
recognized when the customer obtains control of our product, which occurs typically upon receipt by the customer. Our gross product sales are subject to a
variety  of  price  adjustments  in  arriving  at  reported  net  product  sales.  These  adjustments  include  estimates  of  product  returns,  chargebacks,  payment
discounts,  rebates,  and  other  sales  allowances  and  are  estimated  based  on  analysis  of  historical  data  for  the  product  or  comparable  products,  future
expectations for such products and other judgments and analysis.  

License Revenue  

From time to time we may enter into out-licensing agreements which are within the scope of ASC 606 under which it licenses to third parties certain rights
to its products or intellectual property. The terms of these arrangements typically include payment to us of one or more of the following: non-refundable,
upfront license fees; development, regulatory, and commercial milestone payments; and sales-based royalty payments. Each of these payments results in
license revenue. During the years ended December 31, 2019 and 2018, we recognized $0 and $1,846 of revenue from license agreements, respectively.

Research and Development (“R&D”). R&D expenses consist primarily of costs related to clinical studies and outside services, personnel expenses, and
other  R&D  expenses.  Clinical  studies  and  outside  services  costs  relate  primarily  to  services  performed  by  clinical  research  organizations  and  related
clinical or development manufacturing costs, materials and supplies, filing fees, regulatory support, and other third-party fees. Personnel expenses relate
primarily to salaries, benefits and share-based compensation. Other R&D expenses primarily include overhead allocations consisting of various support and
facilities-related costs. R&D expenditures are charged to operations as incurred.

We recognize R&D tax credits received from the French and Irish government for spending on innovative R&D as an offset of R&D expenses.  

Share-based Compensation. We account for share-based compensation based on the estimated grant-date fair value. The fair value of stock options and
warrants is estimated using Black-Scholes option-pricing valuation models (“Black-Scholes model”). As required by the Black-Sholes model, estimates are
made of the underlying volatility of AVDL stock, a risk-free rate and an expected term of the option or warrant. We estimated the expected term using a
simplified method, as we do not have enough historical exercise data for a majority of such options and warrants upon which to estimate an expected term.
We recognize compensation cost, net of an estimated forfeiture rate, using the accelerated method over the requisite service period of the award.

Income Taxes. Our income tax (benefit) provision, deferred tax assets and liabilities, and liabilities for unrecognized tax benefits reflect management’s best
estimate of current and future taxes to be paid. We are subject to income taxes in Ireland, France and the U.S. Significant judgments and estimates are
required in the determination of the consolidated income tax (benefit) provision.

Deferred  income  taxes  arise  from  temporary  differences  between  the  tax  basis  of  assets  and  liabilities  and  their  reported  amounts  in  the  financial
statements, which will result in taxable or deductible amounts in the future. In evaluating our ability to recover our deferred tax assets in the jurisdiction
from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future
taxable income or loss, tax-planning strategies, and results of recent operations. The assumptions about future taxable income or loss require the use of
significant judgment and are consistent with the plans and estimates we are using to manage the underlying businesses.

-46-

   
The  calculation  of  our  tax  liabilities  involves  dealing  with  uncertainties  in  the  application  of  complex  tax  laws  and  regulations  in  a  multitude  of
jurisdictions across our global operations. A tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position
will be sustained upon examination, including resolutions of any related appeals or litigation processes, on the basis of the technical merits.

We record unrecognized tax benefits as liabilities and adjust these liabilities when our judgment changes as a result of the evaluation of new information
not  previously  available.  Because  of  the  complexity  of  some  of  these  uncertainties,  the  ultimate  resolution  may  result  in  a  payment  that  is  materially
different from our current estimate of the unrecognized tax benefit liabilities. These differences will be reflected as increases or decreases to income tax
expense in the period in which new information is available.

We have not recorded a deferred tax liability for any income or withholding taxes that may arise as the result of the distribution of unremitted earnings
within our Company. At December 31, 2019, we had unremitted earnings of $3,961 outside of Ireland as measured on a U.S. GAAP basis. Based on our
estimates that future domestic cash generation will be sufficient to meet future domestic cash needs along with our specific plans for reinvestment, we have
not  recorded  a  deferred  tax  liability  for  any  income  or  withholding  taxes  that  may  arise  from  a  distribution  that  would  qualify  as  a  dividend  for  tax
purposes. It is not practicable to estimate the amount of deferred tax liability on such remittances, if any.

Goodwill.  Goodwill  represents  the  excess  of  the  acquisition  consideration  over  the  fair  value  of  assets  acquired  and  liabilities  assumed.  We  have
determined that we operate in a single segment and has a single reporting unit associated with the development and commercialization of pharmaceutical
products. Prior  to  November  2019,  we  tested  for  goodwill  impairment  using  a  two-step  process.  The  first  step  is  a  comparison  of  the  fair  value  of  the
reporting unit with its carrying amount, including goodwill. If this step indicates impairment, then, in the second step, the loss is measured as the excess of
recorded goodwill over the implied fair value of the goodwill. Implied fair value of goodwill is the excess of the fair value of the reporting unit as a whole
over the fair value of all separately identified assets and liabilities within the reporting unit. As discussed in Note 2: Effect of New Accounting Standards,
we elected to early adopt Accounting Standards Update (“ASU”) 2017-04 in November 2019, which eliminated step 2 from the goodwill impairment test.
We  test  goodwill  for  impairment  annually  and  when  events  or  changes  in  circumstances  indicate  that  the  carrying  value  may  not  be  recoverable.  We
performed our required impairment test of goodwill and have determined that no impairment of goodwill existed at December 31, 2019 and 2018.  

Long-Lived Assets. Long-lived  assets  include  fixed  assets  and  intangible  assets.  Intangible  assets  consist  primarily  of  purchased  licenses  and  intangible
assets  recognized  as  part  of  the  Éclat  Pharmaceuticals  acquisition.  Acquired  IPR&D  has  an  indefinite  life  and  is  not  amortized  until  completion  and
development of the project, at which time the IPR&D becomes an amortizable asset, for which amortization of such intangible assets is computed using the
straight-line method over the estimated useful life of the assets.  

Long-lived  assets  are  reviewed  for  impairment  whenever  conditions  indicate  that  the  carrying  value  of  the  assets  may  not  be  fully  recoverable.  Such
impairment tests are based on a comparison of the pretax undiscounted cash flows expected to be generated by the asset to the recorded value of the asset
or  other  market  based  value  approaches.  If  impairment  is  indicated,  the  asset  value  is  written  down  to  its  market  value  if  readily  determinable  or  its
estimated fair value based on discounted cash flows. Any significant changes in business or market conditions that vary from current expectations could
have  an  impact  on  the  fair  value  of  these  assets  and  any  potential  associated  impairment.  During  the  fourth  quarter  of  2018,  we  recorded  a  $66,087
impairment charge to the entire acquired developed technology related to Noctiva (see Note 9: Goodwill and Intangible Assets). We determined that no
impairment existed at December 31, 2019.

Acquisition-related  Contingent  Consideration.  The  acquisition-related  contingent  consideration  payables  arising  from  the  acquisition  of  Éclat
Pharmaceuticals (i.e., our hospital products) and FSC (our pediatrics products), which was assumed by the buyer as part of the disposition of the pediatrics
products on February 16, 2018, are accounted for at fair-value (see Note 12: Long-Term Related Party Payable and Note 17: Divestiture of the Pediatric
Assets).  The  fair  value  of  the  warrants  issued  in  connection  with  the  Éclat  acquisition  were  estimated  using  a  Black-Scholes  model.  A  portion  of  these
warrants were exercised on February 23, 2018 and the remaining warrants expired on March 12, 2018. See Note 12: Long-Term Related Party Payable.
The  fair  value  of  acquisition-related  contingent  consideration  payable  is  estimated  using  a  discounted  cash  flow  model  based  on  the  long-term  sales  or
gross  profit  forecasts  of  the  specified  hospital  or  pediatric  products  using  an  appropriate  discount  rate.  There  are  a  number  of  estimates  used  when
determining  the  fair  value  of  these  earn-out  payments.  These  estimates  include,  but  are  not  limited  to,  the  long-term  pricing  environment,  market  size,
market share the related products are forecast to achieve, the cost of goods related to such products and an appropriate discount rate to use when present
valuing  the  related  cash  flows.  These  estimates  can  and  often  do  change  based  on  changes  in  current  market  conditions,  competition,  management
judgment  and  other  factors.  Changes  to  these  estimates  can  have  and  have  had  a  material  impact  on  our  consolidated  statements  of  (loss)  income  and
balance sheets. Changes in fair value of these liabilities are recorded in the consolidated statements of (loss) income within operating expenses as changes
in fair value of related party contingent consideration.

Financing-related  Royalty  Agreements.  We  also  entered  into  two  royalty  agreements  with  related  parties  in  connection  with  certain  financing
arrangements. We elected the fair value option for the measurement of the financing-related contingent consideration payable associated with the royalty
agreements with certain Deerfield and Broadfin entities, both of whom are related parties (see Note 12: Long-Term Related Party Payable). The fair value
of  financing-related  royalty  agreements  is  estimated  using  the  same  components  used  to  determine  the  fair  value  of  the  acquisition-related  contingent
consideration noted above, with the exception of cost of products sold. Changes to these components can also have a material impact on our consolidated
statements of (loss) income and balance sheets. Changes in the fair value of this liability are recorded in the consolidated statements of (loss) income as
other (expense) income - changes in fair value of related party payable.

Total  product  sales  were  $59,215  for  the  year  ended  December  31,  2019,  compared  to  $101,423  for  the  same  prior  year  period.  Bloxiverz’s  revenue
declined $13,371 when compared to the same period last year, primarily due to lower net selling prices driven largely by new competitors that entered the
market in 2018 and 2019 and continued market penetration from an alternative molecule to neostigmine. Vazculep’s revenue decreased by $9,764 primarily
due to a decrease in unit volumes and lower realized net selling prices when compared to the prior year. Akovaz’s revenue decreased $15,117 driven by
lower  unit  volumes  and  net  selling  prices  due  largely  to  new  competitors  that  entered  the  market  in  2018  and  2019.  Other  revenues,  which  includes
Noctiva, which was deconsolidated in February 2019, and the pediatric products, which were divested in February 2018, declined when compared to the
prior year due to the divestiture of those products as well as an increased returns reserve related to these products during the year ended December 31,
2019.

License  and  research  revenue  was  $0  for  the  year  ended  December  31,  2019  compared  to  $1,846  in  the  same  period  last  year.  In  December  2018,  we
reached an agreement to exit a contract and our remaining performance obligations and recognized the remaining $1,600 of deferred revenue during the
year ended December 31, 2018, which represented the unsatisfied performance obligations associated with a license agreement.

R&D expenses decreased $6,412 or 16.3% during the year ended December 31, 2019 as compared to the same period in 2018. This decline was a result of
$2,800 of lower spending associated with the exit of Noctiva, lower payroll, benefits and share-based compensation of $2,900 related to the 2019 Corporate
and French restructuring plans and approximately $900 of cost reductions at our Lyon, France R&D center. We continue to invest a substantial portion of
R&D in our FT218 development program.

Selling, general and administrative (“SG&A”) expenses decreased $70,176 or 69.9% during the year ended December 31, 2019 as compared to the prior
year. This decrease was primarily due to a decrease of $60,100 of sales and marketing costs related to the exit of Noctiva during the first quarter 2019 as
well as $2,700 of decreased costs due to the 2018 divestiture of the pediatric products. Also contributing to the decrease is lower overall payroll and share-
based compensation of $7,200 due to reduced headcount as a result of the 2019 Corporate and French restructuring plans.

We compute the fair value of the related party contingent consideration using several significant assumptions and when these assumptions change, due to
underlying market conditions, the fair value of these liabilities change as well. Each of the underlying assumptions used to determine the fair values of
these contingent liabilities can, and often do, change based on adjustments in current market conditions, competition and other factors. These changes can
have a material impact on our consolidated statements of loss (income) and balance sheets.  

As a result of changes in the underlying assumptions used to determine the estimated fair values of our acquisition-related contingent consideration earn-
out  payments  -  Éclat,  we  recorded  expense  of  $845  and  a  gain  of  $22,731  and  increased/lowered  the  fair  value  of  the  acquisition-related  contingent
consideration earn-out payments - Éclat for the years ended December 31, 2019 and 2018, respectively. In Item 7 Critical Accounting Estimates, there are
numerous  assumptions  and  estimates  we  use  when  determining  the  fair  value  of  the  acquisition-related  earn-out  payments  -  Éclat.  These  assumptions
include estimates of pricing, market size, the market share the related products are forecast to achieve, the cost of goods related to such products and an
appropriate discount rate to use when determining the present value of the related cash flows.

For the year ended December 31, 2019, as a result of changes to these estimates when compared to the same estimates at December 31, 2018, we recorded
an  increase  in  the  fair  value  of  our  contingent  consideration  liabilities.  The  increase  was  due  to  the  timing  of  anticipated  market  competition  when
compared to the original estimates.

During  the  fourth  quarter  of  2018,  an  impairment  charge  of  $66,087  was  recorded  to  write-off  the  remaining  carrying  value  of  the  acquired  developed
technology intangible asset related to Noctiva. During the fourth quarter 2018, certain conditions came to light, largely the lack of a meaningful increase in
Noctiva prescriptions despite the substantial investment of resources, which indicated that the carrying value of the asset, may not be fully recoverable. As
such, we performed an impairment test based on

a comparison of the pretax discounted cash flows expected to be generated by the asset, which is a Level 3 fair value estimate, to the recorded value of the
asset  and  concluded  that  the  associated  cash  flows  did  not  support  any  of  the  carrying  value  of  the  intangible  asset  and  we  recorded  a  full  impairment
charge. The Chapter 11 bankruptcy filing of Avadel Specialty Pharmaceuticals, LLC (“Specialty Pharma”) commenced on February 6, 2019, the subsidiary
which marketed, sold and distributed Noctiva, confirmed management’s conclusion on the impairment. There were no such impairment charges during the
year ended December 31, 2019.

In 2019, the income tax benefit decreased by $12,537 when compared to the same period in 2018. The decrease in the income tax benefit in 2019 was
primarily driven by the impairment of the Noctiva intangible asset in 2018, which did not recur in 2019. In addition to the non-recurring impairment, an
increase in the valuation allowance in 2019, when compared to the same period in 2018 also contributed to the decrease in tax benefit recorded in 2019. As
a part of a corporate reorganization, the Company entered into an internal sale transaction in December 2019. The internal sale transaction included transfer
of  intangible  assets  from  an  Irish  entity  to  a  U.S.  entity.  The  internal  sale  transaction  resulted  in  a  decrease  of  $5,536  to  Irish  deferred  tax  asset  with
corresponding decrease of $5,536 to valuation allowance, an increase of $8,190 to U.S. deferred tax asset associated with amortization of intangible assets,
and a $8,190 deferred tax benefit.

Net cash used in operating activities of $38,325 for the year ended December 31, 2019 decreased from net cash used in operating activities of $82,716 in
the prior year. This decrease in cash used in operating activities is driven by lower cash loss (net loss adjusted for non-cash credits and charges) of $20,858
when  compared  to  the  same  period  last  year.  This  decrease  is  driven  by  less  cash  used  in  SG&A  and  R&D  expenses  in  the  current  year  driven  by  the
Specialty Pharma bankruptcy and deconsolidation, partially offset by lower revenue in the current year when compared to the prior year. The decrease in
cash  used  in  operating  activities  was  also  due  to  the  increase  in  accounts  payable  and  accrued  expenses  of  $17,670  and  a  decrease  in  the  earn-out  and
royalty payments for related party contingent payable of $9,570 during the year ended December 31, 2019 compared to the prior year.

Investing Activities 

Cash provided by investing activities was $38,723 for the year ended December 31, 2019 compared to cash used in investing activities of $36,981 in the
same prior year period. In 2019, we had net proceeds of $38,598 for the sale of marketable securities compared to our use of $16,803 cash for the purchase
of marketable securities during the year ended December 31, 2018. Additionally, we also had a $20,000 Noctiva related milestone payment as part of the
Exclusive License and Assignment Agreement with Serenity Pharmaceuticals, LLC (“Serenity”) during the year ended December 31, 2018.

Financing Activities 

Cash used in financing activities of $27 for the year ended December 31, 2019 decreased $112,686 compared to cash provided by financing activities of
$112,659 for the same prior year period. During the year ended December 31, 2018, $143,750 of cash was provided by financing activities through the
issuance of the 2023 Notes. A portion of the proceeds from the offering of the 2023 Notes was used for share repurchases totaling $27,637 and to pay direct
expenses associated with the issuance of the 2023 Notes of $6,190 during the first half of 2018.

Liquidity and Risk Management 

The adequacy of our cash resources depends on the outcome of certain business conditions including the cost of our FT218 clinical development plan, our
cost structure, our hospital products revenue stream and other factors set forth in “Risk Factors” within Part I, Item 1A of this Annual Report on Form 10-
K. To complete the FT218 clinical development plan and to ensure an adequate and robust NDA for filing with the FDA we will need to commit substantial
resources, which could result in future losses or otherwise limit our opportunities or affect our ability to operate our business. Our assumptions concerning
the outcome of certain business conditions may prove to be wrong or other factors may adversely affect our business, and as a result we could exhaust or
significantly decrease our available cash and marketable securities balances which could, among other things, force us to raise additional funds and/or force
us  to  reduce  our  expenses,  either  of  which  could  have  a  material  adverse  effect  on  our  business.  If  available  to  us  raising  additional  capital  may  be
accomplished through one or more public or private debt or equity financings, collaborations or partnering arrangements. Any equity financing would be
dilutive to our shareholders.

On  February  21,  2020,  we  announced  that  we  have  entered  into  a  definitive  agreement  for  the  sale  of  our  ADSs  and  Series  A  Non-Voting  Convertible
Preferred Shares (“Series A Preferred”) in a private placement to a group of institutional accredited investors. The private placement has resulted in gross
proceeds of approximately $65,000 before deducting placement agent and other offering expenses, and resulting in net proceeds of approximately $61,000.

Borrowings

In February 2018, we issued the 2023 Notes. We received net proceeds of approximately $137,560 from the sale of the 2023 Notes, after deducting fees
and expenses of $6,190.

Share Repurchase Programs

We fully completed our authorized share buyback program during the year ended December 31, 2018. No share purchases were made during the year ended
December 31, 2019.

Other Matters 

Litigation  

We are subject to potential liabilities generally incidental to our business arising out of present and future lawsuits and claims related to product liability,
personal injury, contract, commercial, intellectual property, tax, employment, compliance and other matters that arise in the ordinary course of business. We
accrue for potential liabilities when it is probable that future costs (including legal fees and expenses) will be incurred and such costs can be reasonably
estimated. At December 31, 2019 and December 31, 2018, there were no contingent liabilities with respect to any litigation, arbitration or administrative or
other  proceeding  that  are  reasonably  likely  to  have  a  material  adverse  effect  on  our  consolidated  financial  position,  results  of  operations,  cash  flows  or
liquidity.

Note 3: Subsidiary Bankruptcy and Deconsolidation briefly describes the Chapter 11 bankruptcy case which our subsidiary Specialty Pharma commenced
on  February  6,  2019,  and  which  on  April  26,  2019  resulted  in  the  bankruptcy  court-approved  sale  of  all  of  Specialty  Pharma’s  intangible  assets  and
inventory  to  an  unaffiliated  third  party.  As  a  result  of  such  sale,  Specialty  Pharma  has  completed  its  divestment  of  the  assets  of  the  Noctiva  business.
During  the  pendency  of  the  bankruptcy  case,  all  pending  litigation  against  Specialty  Pharma  is  automatically  stayed  and  any  new  litigation  against
Specialty Pharma is precluded unless the bankruptcy court orders otherwise. Below are descriptions of a litigation to which Specialty Pharma is a party and
a contract dispute involving Specialty Pharma, both of which matters are subject to the automatic stay during the bankruptcy case.

Ferring  Litigation.  Some  of  the  patents  covering  the  Noctiva  product  (the  “Noctiva  Patents”)  are  the  subject  of  litigation  initiated  by  Ferring
Pharmaceuticals Inc. and two of its foreign affiliates, who manufacture a competing product known as Nocdurna.  Nocdurna was approved by the FDA in
June 2018 and commercially launched in the U.S. in November 2018.  In this litigation, filed in the United States District Court for the Southern District of
New York, Ferring seeks to invalidate and disputes the inventorship of the Noctiva Patents, seeks damages for various alleged breaches of contractual and
common  law  duties,  and  seeks  damages  for  alleged  infringement  by  Noctiva  of  Ferring’s  “Nocdurna”  trademark.    Specialty  Pharma  and  certain  other
parties  including  Serenity  Pharmaceuticals,  LLC  (“Serenity”)  (the  licensor  of  the  Noctiva  Patents)  have  defended  this  litigation,  and  have  made
counterclaims against Ferring, including for infringement of the Noctiva Patents and a declaratory judgment of noninfringement with respect to Ferring’s
“Nocdurna”  trademark.  The  court  dismissed  Ferring’s  inventorship  claim  and  its  claims  for  alleged  breaches  of  contractual  and  common  law  duties,
although these dismissals may be appealed by Ferring.  On February 15, 2019, Specialty Pharma and its co-defendants moved to stay the litigation pending
completion of the bankruptcy proceeding of Specialty Pharma. On May 15, 2019, that motion was denied due to a pending settlement of the litigation with
respect  to  just  Ferring  and  Specialty  Pharma.  On  February  25,  2020,  Ferring  and  Specialty  Pharma  jointly  moved  for  bankruptcy  court  approval  of  a
settlement agreement with respect to the claims alleged in the litigation.  In accordance with the terms of the settlement agreement, promptly following
bankruptcy court approval of the settlement agreement, the parties would dismiss with prejudice their respective claims against each other in the litigation. 
On March 13th, 2020, the bankruptcy court entered an order approving the settlement with Ferring.  Pursuant to the terms of the settlement, the parties are
to  dismiss  their  respective  claims  against  each  other  in  the  District  Court  litigation  in  the  Southern  District  of  New  York,  with  such  dismissals  to  be
effective concurrently.  That joint dismissal has not yet been filed with District Court for the Southern District of New York.

Contract Dispute. On January 21, 2019, Serenity gave notice to Specialty Pharma of an alleged breach of the parties’ Noctiva license agreement. Serenity
alleges that Specialty Pharma breached its contractual obligation to devote commercially reasonable efforts to the commercialization of Noctiva and seeks
unspecified damages. On January 27, 2019, Specialty Pharma notified Serenity of a claim for $1.7 million in damages as a result of Serenity’s breach of its
contractual  obligation  to  pay  the  costs  of  the  Ferring  Litigation.  Serenity’s  notice  to  Specialty  Pharma  invoked  the  dispute  resolution  provisions  of  the
Noctiva license agreement, which culminate in arbitration, but neither party has yet initiated an arbitration proceeding or filed suit.

Exela Litigation.  On January 7, 2020, Exela filed a complaint against us and our subsidiary, Avadel Legacy in the United States District for the District of
Delaware. The complaint alleges infringement of a certain Exela patent related to its cysteine hydrochloride product. Exela is most notably seeking i) a
declaratory judgment that the Nouress product infringes its patent, ii)

-54-

an injunction (both preliminary and permanent) precluding the launch of Nouress, and iii) monetary damages (including enhanced damages, prejudgment
interest and attorneys’ fees) in the event Nouress is commercially launched and found to infringe Exela’s patent.  We have not yet been served with the
complaint.

Former employee dispute. On January 10, 2020, we settled a dispute with a former employee for $1,750.

Material Commitments  

At  December  31,  2019,we  had  various  commitments  to  purchase  finished  product  from  customers.  Commitments  for  these  arrangements,  at  maximum
quantities  and  at  contractual  prices  over  the  remaining  life  of  the  contract,  and  excluding  any  waived  commitments,  are  as  follows  for  the  years  ended
December 31:

We also had a commitment with a contract manufacturer related to the construction and preparation of a production suite at the contract manufacturer’s
facility, which is substantially complete at December 31, 2019. Subsequent to the initial build and preparation of the production suite, this commitment also
includes annual fees which would commence at the time of FDA approval of the product and continue thereafter for five years. These amounts are not
included in the table above, as the start date has not been determined.

We and our subsidiaries lease office facilities under non-cancellable operating leases expiring at various dates. See Note 10: Leases for disclosure of these.

Other  than  the  above  commitments,  there  were  no  other  material  commitments  outside  of  the  normal  course  of  business.  Material  commitments  in  the
normal  course  of  business  include  long-term  debt  and  long-term  related  party  payable,  which  are  disclosed  in  Item  8.  Financial  Statements  and
Supplementary Data, Note 11: Long-Term Debt and Note 12: Long-Term Related Party Payable, respectively.

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

Interest Rate Risk

We are subject to interest rate risk as a result of our portfolio of marketable securities. The primary objectives of our investment policy are as follows:
safety and preservation of principal and diversification of risk; liquidity of investments sufficient to meet cash flow requirements; and competitive yield.
Although our investments are subject to market risk, our investment policy specifies credit quality standards for our investments and limits the amount of
credit exposure from any single issue, issuer or certain types of investment. Our investment policy allows us to maintain a portfolio of cash equivalents and
marketable securities in a variety of instruments, including U.S. federal government and federal agency securities, European Government bonds, corporate
bonds or commercial paper issued by U.S. or European corporations, money market instruments, certain qualifying money market mutual funds, certain
repurchase agreements, tax-exempt obligations of states, agencies, and municipalities in the U.S and Europe, and equities. 

Foreign Exchange Risk

We are exposed to foreign currency exchange risk as the functional currency financial statements of a non-U.S. subsidiary is translated to U.S. dollars. The
assets and liabilities of this non-U.S. subsidiary having a functional currency other than the U.S. dollar is translated into U.S. dollars at the exchange rate
prevailing at the balance sheet date, and at the average exchange rate for the reporting period for revenue and expense accounts. The cumulative foreign
currency translation adjustment is recorded as a component of accumulated other comprehensive loss in shareholders’ equity. The reported results of this
non-U.S.  subsidiary  will  be  influenced  by  their  translation  into  U.S.  dollars  by  currency  movements  against  the  U.S.  dollar.  Our  primary  currency
translation exposure is related to one subsidiary that has functional currencies denominated in euro. A 10% strengthening/weakening in the rates used to
translate  the  results  of  our  non-U.S.  subsidiaries  that  have  functional  currencies  denominated  in  euro  as  of  December  31,  2019  would  have  had  an
immaterial impact on net loss for the year ended December 31, 2019.

Transactional exposure arises where transactions occur in currencies other than the functional currency. Transactions in foreign currencies are recorded at
the  exchange  rate  prevailing  at  the  date  of  the  transaction.  The  resulting  monetary  assets  and  liabilities  are  translated  into  the  appropriate  functional
currency  at  exchange  rates  prevailing  at  the  balance  sheet  date  and  the  resulting  gains  and  losses  are  reported  in  foreign  exchange  gain  (loss)  in  the
consolidated statements of (loss) income.  As of December 31, 2019, our primary exposure is to transaction risk related to Euro net monetary assets and
liabilities held by subsidiaries with a U.S. dollar functional currency. Realized and unrealized foreign exchange gains resulting from transactional exposure
were immaterial for the year ended December 31, 2019.

AVADEL PHARMACEUTICALS PLC
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(In thousands, except per share data)

NOTE 1: Summary of Significant Accounting Policies

Nature of Operations. Avadel Pharmaceuticals plc (Nasdaq: AVDL) (“Avadel,” the “Company,” “we,” “our,” or “us”) is an emerging biopharmaceutical
company.  Our  lead  product  candidate,  FT218,  is  an  investigational  once-nightly  formulation  of  sodium  oxybate  for  the  treatment  of  excessive  daytime
sleepiness (“EDS”), and cataplexy in narcolepsy patients. FT218, which uses our Micropump drug-delivery technology, is in a Phase 3 clinical trial for the
treatment  of  narcolepsy  patients  suffering  from  EDS  and  cataplexy.  In  addition,  we  have  three  approved  commercial  products  developed  under  our
“unapproved marketed drug,” or UMD, program, Akovaz, Bloxiverz and Vazculep, and a fourth approved product, Nouress, which are sterile injectable
drugs used in the hospital setting.

We are primarily focused on the development and potential U.S. Food and Drug Administration (“FDA”) approval of FT218. In addition, we continue to
market  and  distribute  our  current  approved  hospital  products  portfolio  and,  pending  resolution  of  the  existing  patent  infringement  claim  (as  described
below), we plan to commercialize Nouress. Outside of our product candidate and our existing commercial products, we continue to evaluate opportunities
to expand our product portfolio.

Current marketed products

Bloxiverz (neostigmine methylsulfate injection) - Bloxiverz was approved by the FDA in May 2013 and was launched in July 2013. Bloxiverz
is a drug used intravenously in the operating room to reverse the effects of non-depolarizing neuromuscular blocking agents after surgery.
Bloxiverz was the first FDA-approved version of neostigmine methylsulfate. Today, neostigmine is one of the two most frequently used
products for the reversal of the effects of other agents used for neuromuscular blocks.

Vazculep  (phenylephrine  hydrochloride  injection)  -  Vazculep  was  approved  by  the  FDA  in  June  2014  and  was  launched  in  October  2014.

Vazculep is indicated for the treatment of clinically important hypotension occurring in the setting of anesthesia.

Akovaz (ephedrine sulfate injection). Akovaz, was approved by the FDA in April 2016 and was launched in August 2016. Akovaz was the first
FDA  approved  formulation  of  ephedrine  sulfate,  an  alpha-  and  beta-  adrenergic  agonist  and  a  norepinephrine-releasing  agent  that  is
indicated for the treatment of clinically important hypotension occurring in the setting of anesthesia.

Nouress

In December 2019, we received FDA approval for Nouress (cysteine hydrochloride injection), a sterile injectable product for use in the hospital setting, and
currently have two patents covering that product. Several additional patent applications for Nouress are pending with the USPTO. In light of the recently
filed patent suit by Exela Pharma Sciences, LLC, we are currently evaluating the timing and process for a commercial launch of Nouress in the U.S.  See
Note 16: Contingent Liabilities and Commitments.

The Company was incorporated in Ireland on December 1, 2015 as a private limited company, and re-registered as an Irish public limited company on
November 21, 2016. Our headquarters are in Dublin, Ireland and we have operations in St. Louis, Missouri, U.S., and Lyon, France.

Basis of Presentation. These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the U.S.
(U.S. GAAP). The consolidated financial statements include the accounts of the Company and all subsidiaries. All intercompany accounts and transactions
have been eliminated. 

On February 6, 2019, the Company’s indirect wholly-owned subsidiary, Avadel Specialty Pharmaceuticals, LLC (“Specialty Pharma”), filed a voluntary
petition for reorganization under Chapter 11 of the U.S. Code (the “Bankruptcy Code”). in the U.S. District Bankruptcy Court for the District of Delaware
(the “Bankruptcy Court”), Case No. 19-10248. Specialty Pharma is operating and managing its business as “debtors-in-possession” under the jurisdiction
of  the  Bankruptcy  Court  and  in  accordance  with  the  applicable  provisions  of  the  Bankruptcy  Code  and  order  of  the  Bankruptcy  Court.  As  a  result  of
Specialty  Pharma’s  voluntary  bankruptcy  filing  on  February  6,  2019,  we  no  longer  controlled  the  operations  of  Specialty  Pharma;  therefore,  we
deconsolidated Specialty Pharma effective with the bankruptcy filing and the Company recorded its investment in Specialty Pharma under the cost method.
See Note 3: Subsidiary Bankruptcy and Deconsolidation. Our results of operations for the period January 1, 2019

-62-

through February 6, 2019 include the results of Specialty Pharma prior to its February 6, 2019 voluntary petition for reorganization under Chapter 11 of the
U.S. Bankruptcy Code.

Our results of operations for the period January 1, 2018 through February 16, 2018 and for the year ended December 31, 2017 include the results of FSC
Therapeutics and FSC Laboratories, Inc., (collectively “FSC”), prior to its February 16, 2018 disposition date. See Note 17: Divestiture of the Pediatric
Assets, for additional information.

Revenue.  Revenue  includes  sales  of  pharmaceutical  products,  licensing  fees,  and,  if  any,  milestone  payments  for  research  and  development  (“R&D”)
achievements.

Effective  January  1,  2018,  the  Company  adopted  Accounting  Standards  Codification  (“ASC”)  Topic  606,  “Revenue  from  Contracts  with
Customers” (“ASC 606”) using the modified retrospective transition method applied to all open contracts as at December 31, 2017. The adoption of the
new  standard  did  not  have  a  material  effect  on  the  overall  timing  or  amount  of  revenue  recognized  when  compared  to  prior  accounting  standards.
See Note 4: Revenue Recognition.

ASC 606 applies to all contracts with customers, except for contracts that are within the scope of other standards, such as leases, insurance, collaboration
arrangements  and  financial  instruments.  Under  ASC  606,  an  entity  recognizes  revenue  when  the  performance  obligations  to  the  customer  have  been
satisfied  through  the  transfer  of  control  of  the  goods  or  services.  To  determine  the  appropriate  revenue  recognition  for  arrangements  that  the  Company
believes are within the scope of ASC 606, we perform the following five steps: (i) Identify the contract(s) with a customer; (ii) Identify the performance
obligations in the contract; (iii) Determine the transaction price; (iv) Allocate the transaction price to the performance obligations in the contract; and (v)
Recognize  revenue  when  (or  as)  the  entity  satisfies  a  performance  obligation.  The  Company  applies  the  five-step  model  to  contracts  only  when  the
Company and its customer’s rights and obligations under the contract can be determined, the contract has commercial substance, and it is probable that the
Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. For contracts that are determined
to be within the scope of ASC 606, the Company identifies the promised goods or services in the contract to determine if they are separate performance
obligations or if they should be bundled with other goods and services into a single performance obligation. The Company then recognizes as revenue the
amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

Product Sales  

We  sell  products  primarily  through  wholesalers  and  considers  these  wholesalers  to  be  its  customers.  Under  ASC  606,  revenue  from  product  sales  is
recognized when the customer obtains control of our product, which occurs typically upon receipt by the customer. Our gross product sales are subject to a
variety  of  price  adjustments  in  arriving  at  reported  net  product  sales.  These  adjustments  include  estimates  of  product  returns,  chargebacks,  payment
discounts,  rebates,  and  other  sales  allowances  and  are  estimated  based  on  analysis  of  historical  data  for  the  product  or  comparable  products,  future
expectations for such products and other judgments and analysis.  

License Revenue  

From time to time we may enter into out-licensing agreements which are within the scope of ASC 606 under which it licenses to third parties certain rights
to its products or intellectual property. The terms of these arrangements typically include payment to us of one or more of the following: non-refundable,
upfront license fees; development, regulatory, and commercial milestone payments; and sales-based royalty payments. Each of these payments results in
license revenue.

For a complete discussion of the accounting for net product revenue and license revenues, see Note 4: Revenue Recognition.

Research and Development (“R&D”). R&D expenses consist primarily of costs related to clinical studies and outside services, personnel expenses, and
other  R&D  expenses.  Clinical  studies  and  outside  services  costs  relate  primarily  to  services  performed  by  clinical  research  organizations  and  related
clinical or development manufacturing costs, materials and supplies, filing fees, regulatory support, and other third-party fees. Personnel expenses relate
primarily to salaries, benefits and share-based compensation. Other R&D expenses primarily include overhead allocations consisting of various support and
facilities-related costs. R&D expenditures are charged to operations as incurred.  

We recognize R&D tax credits received from the French and Irish government for spending on innovative R&D as an offset of R&D expenses.  

-63-

Advertising  Expenses.  We  expense  the  costs  of  advertising  as  incurred.  Advertising  expenses  were  $372,  $17,562  and  $2,214  for  the  years  ended
December  31,  2019,  2018  and  2017,  respectively.  The  decrease  in  advertising  for  the  year  ended  December  31,  2019  is  due  to  Specialty  Pharma’s
bankruptcy and deconsolidation. See Note 3: Subsidiary Bankruptcy and Deconsolidation.

Share-based Compensation. We account for share-based compensation based on the estimated grant-date fair value. The fair value of stock options and
warrants is estimated using Black-Scholes option-pricing valuation models (“Black-Scholes model”). As required by the Black-Sholes model, estimates are
made of the underlying volatility of AVDL stock, a risk-free rate and an expected term of the option or warrant. We estimated the expected term using a
simplified method, as we do not have enough historical exercise data for a majority of such options and warrants upon which to estimate an expected term.
We recognize compensation cost, net of an estimated forfeiture rate, using the accelerated method over the requisite service period of the award.

Income Taxes. We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the
expected future tax consequences of events that have been included in the financial statements. Under this method, we determine deferred tax assets and
liabilities on the basis of the differences between the financial statement and tax bases of assets and liabilities by using enacted tax rates in effect for the
year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the
period that includes the enactment date.

We recognize deferred tax assets to the extent that we believe that these assets are more likely than not to be realized. In making such a determination, we
consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income,
tax-planning strategies, and results of recent operations. If we determine that we would be able to realize our deferred tax assets in the future in excess of
their net recorded amount, we would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.

We record uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) we determine whether it is more likely than
not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-
not recognition threshold, we recognize the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the
related tax authority.

We recognize interest and penalties related to unrecognized tax benefits in the income tax expense line in the accompanying consolidated statements of
(loss) income. Accrued interest and penalties are included on the related tax liability line in the consolidated balance sheets.

Cash  and  Cash  Equivalents.  Cash  and  cash  equivalents  consist  of  cash  on  hand,  cash  on  deposit  and  fixed  term  deposits  which  are  highly  liquid
investments with original maturities of less than three months.  

Marketable Securities. The Company’s marketable securities are considered to be available for sale and are carried at fair value, with unrealized gains and
losses, net of taxes, reported as a component of accumulated other comprehensive (loss) income (“AOCI”) in shareholders’ equity, with the exception of
unrealized gains and losses on equity instruments and unrealized losses believed to be other-than-temporary, if any, which are reported in earnings in the
current period. The cost of securities sold is based upon the specific identification method.  

Accounts Receivable. Accounts receivable are stated at amounts invoiced net of allowances for doubtful accounts and certain other gross to net variable
consideration deductions. The Company makes judgments as to our ability to collect outstanding receivables and provides allowances for the portion of
receivables deemed uncollectible. Provision is made based upon a specific review of all significant outstanding invoices. A majority of accounts receivable
is due from four significant customers.  

Inventories. Inventories consist of raw materials and finished products, which are stated at lower of cost or net realizable value, using the first-in, first-out
(“FIFO”) method. Raw materials used in the production of pre-clinical and clinical products are expensed as R&D costs when consumed. The Company
establishes reserves for inventory estimated to be obsolete, unmarketable or slow-moving on a case by case basis.  

Property and Equipment. Property and equipment is stated at historical cost less accumulated depreciation. Depreciation and amortization are computed
using the straight-line method over the following estimated useful lives:

Laboratory equipment

Software, office and computer equipment

Leasehold improvements, furniture, fixtures and fittings

4-8 years

3 years

5-10 years

-64-

 
Goodwill.  Goodwill  represents  the  excess  of  the  acquisition  consideration  over  the  fair  value  of  assets  acquired  and  liabilities  assumed.  We  have
determined that we operate in a single segment and has a single reporting unit associated with the development and commercialization of pharmaceutical
products. Prior  to  November  2019,  we  tested  for  goodwill  impairment  using  a  two-step  process.  The  first  step  is  a  comparison  of  the  fair  value  of  the
reporting unit with its carrying amount, including goodwill. If this step indicates impairment, then, in the second step, the loss is measured as the excess of
recorded goodwill over the implied fair value of the goodwill. Implied fair value of goodwill is the excess of the fair value of the reporting unit as a whole
over the fair value of all separately identified assets and liabilities within the reporting unit. As discussed in Note 2: Effect of New Accounting Standards,
we elected to early adopt Accounting Standards Update (“ASU”) 2017-04 in November 2019, which eliminated step 2 from the goodwill impairment test.
We  test  goodwill  for  impairment  annually  and  when  events  or  changes  in  circumstances  indicate  that  the  carrying  value  may  not  be  recoverable.  We
performed our required impairment test of goodwill and have determined that no impairment of goodwill existed at December 31, 2019 and 2018.

Long-Lived Assets. Long-lived  assets  include  fixed  assets  and  intangible  assets.  Intangible  assets  consist  primarily  of  purchased  licenses  and  intangible
assets  recognized  as  part  of  the  Éclat  Pharmaceuticals  acquisition.  Acquired  IPR&D  has  an  indefinite  life  and  is  not  amortized  until  completion  and
development of the project, at which time the IPR&D becomes an amortizable asset, for which amortization of such intangible assets is computed using the
straight-line method over the estimated useful life of the assets.  

Long-lived  assets  are  reviewed  for  impairment  whenever  conditions  indicate  that  the  carrying  value  of  the  assets  may  not  be  fully  recoverable.  Such
impairment tests are based on a comparison of the pretax undiscounted cash flows expected to be generated by the asset to the recorded value of the asset
or  other  market  based  value  approaches.  If  impairment  is  indicated,  the  asset  value  is  written  down  to  its  market  value  if  readily  determinable  or  its
estimated fair value based on discounted cash flows. Any significant changes in business or market conditions that vary from current expectations could
have  an  impact  on  the  fair  value  of  these  assets  and  any  potential  associated  impairment.  During  the  fourth  quarter  of  2018,  we  recorded  a  $66,087
impairment charge to the entire acquired developed technology related to Noctiva (see Note 9: Goodwill and Intangible Assets). We determined that no
impairment existed at December 31, 2019.

Lease Obligations. On January 1, 2019, the Company adopted ASU 2016-02, “Leases” which supersedes ASC 840 “Leases” and creates a new topic, ASC
842 “Leases”. The Company adopted ASU 2016-02 using the modified retrospective transition approach and elected the transition option to recognize the
adjustment in the period of adoption rather than in the earliest period presented. Results and disclosure requirements for reporting periods beginning after
January 1, 2019 are presented under Topic 842, while prior period amounts have not been adjusted and continue to be reported in accordance with our
historical accounting under Topic 840. Upon  adoption,  we  recognized  total  ROU  assets  of  $5,046,  with  corresponding  lease  liabilities  of  $5,131  on  the
consolidated  balance  sheets.  The  adoption  did  not  impact  our  beginning  retained  earnings,  or  our  prior  year  consolidated  statements  of  income  and
statements of cash flows.

The Company elected the package of practical expedients permitted under the transition guidance, which allowed us to carryforward our historical lease
classification, our assessment on whether a contract was or contains a lease, and our initial direct costs for any leases that existed prior to January 1, 2019.
The Company also elected to combine our lease and non-lease components and to keep leases with an initial term of 12 months or less off the balance sheet
and recognize the associated lease payments in the consolidated statements of (loss) income on a straight-line basis over the lease term.

Under ASU 2016-02, the Company determines if a contract is a lease at the inception of the arrangement. Right-of-use assets and operating lease liabilities
are  recognized  at  commencement  date  based  on  the  present  value  of  remaining  lease  payments  over  the  lease  term.  For  this  purpose,  the  Company
considers only payments that are fixed and determinable at the time of commencement. The Company reviews all options to extend, terminate, or purchase
its right-of-use assets at the inception of the lease and will include these options in the lease term when they are reasonably certain of being exercised.
Nearly all of the Company’s lease contracts do not provide a readily determinable implicit rate. For these contracts, the Company’s estimated incremental
borrowing  rate  is  based  on  information  available  at  the  inception  of  the  lease.  Our  lease  agreements  may  contain  variable  costs  such  as  common  area
maintenance, insurance, real estate taxes or other costs. Variable lease costs are expensed as incurred on the consolidated statements of income.

Acquisition-related  Contingent  Consideration.  The  acquisition-related  contingent  consideration  payables  arising  from  the  acquisition  of  Éclat
Pharmaceuticals (i.e., our hospital products) and FSC (our pediatrics products), which was assumed by the buyer as part of the disposition of the pediatrics
products on February 16, 2018, are accounted for at fair-value (see Note 12: Long-Term Related Party Payable and Note 17: Divestiture of the Pediatric
Assets).  The  fair  value  of  the  warrants  issued  in  connection  with  the  Éclat  acquisition  were  estimated  using  a  Black-Scholes  model.  A  portion  of  these
warrants were exercised on February 23, 2018 and the remaining warrants expired on March 12, 2018. See Note 12: Long-Term Related Party Payable.
The fair value

-65-

of  acquisition-related  contingent  consideration  payable  is  estimated  using  a  discounted  cash  flow  model  based  on  the  long-term  sales  or  gross  profit
forecasts of the specified hospital or pediatric products using an appropriate discount rate. There are a number of estimates used when determining the fair
value of these earn-out payments. These estimates include, but are not limited to, the long-term pricing environment, market size, market share the related
products are forecast to achieve, the cost of goods related to such products and an appropriate discount rate to use when present valuing the related cash
flows. These  estimates  can  and  often  do  change  based  on  changes  in  current  market  conditions,  competition,  management  judgment  and  other  factors.
Changes to these estimates can have and have had a material impact on our consolidated statements of (loss) income and balance sheets. Changes in fair
value of these liabilities are recorded in the consolidated statements of (loss) income within operating expenses as changes in fair value of related party
contingent consideration.

Financing-related  Royalty  Agreements.  We  also  entered  into  two  royalty  agreements  with  related  parties  in  connection  with  certain  financing
arrangements. We elected the fair value option for the measurement of the financing-related contingent consideration payable associated with the royalty
agreements with certain Deerfield and Broadfin entities, both of whom are related parties (see Note 12: Long-Term Related Party Payable). The fair value
of  financing-related  royalty  agreements  is  estimated  using  the  same  components  used  to  determine  the  fair  value  of  the  acquisition-related  contingent
consideration noted above, with the exception of cost of products sold. Changes to these components can also have a material impact on our consolidated
statements of (loss) income and balance sheets. Changes in the fair value of this liability are recorded in the consolidated statements of (loss) income as
other (expense) income - changes in fair value of related party payable.

Use  of  Estimates.  The  preparation  of  consolidated  financial  statements  in  conformity  with  U.S.  GAAP  requires  management  to  make  estimates  and
assumptions  that  affect  the  reported  amounts  of  assets  and  liabilities,  including  marketable  securities  and  contingent  liabilities  at  the  date  of  the
consolidated financial statements and the reported amounts of sales and expenses during the periods presented. These estimates and assumptions are based
on the best information available to management at the balance sheet dates and depending on the nature of the estimate can require significant judgments.
Changes to these estimates and judgments can have and have had a material impact on our consolidated statements of (loss) income and balance sheets.
Actual results could differ from those estimates under different assumptions or conditions.  

NOTE 2: Newly Issued Accounting Standards 

Recently Adopted Accounting Guidance

In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, “Leases” which supersedes ASC 840 “Leases” and creates a
new topic, ASC 842 “Leases.” This update requires lessees to recognize on their balance sheet a lease liability and a lease asset for all leases, including
operating leases, with a term greater than 12 months. The update also expands the required quantitative and qualitative disclosures surrounding leases. This
update is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years, with earlier application permitted. In
July  2018,  the  FASB  issued ASU  2018-11  “Targeted  Improvements”,  amending  certain  aspects  of  the  new  leasing  standard.  The  amendment  allows  an
additional optional transition method whereby an entity records a cumulative effect adjustment to opening retained earnings in the year of adoption without
restating prior periods, which the Company has elected. The Company adopted this ASU during the first quarter of 2019. See Note 10: Leases for more
information.

In  January  2017,  the  FASB  issued  ASU  2017-04,  “Intangibles  -  Goodwill  and  Other:  Simplifying  the  Test  for  Goodwill  Impairment.”  This  update
eliminates step 2 from the goodwill impairment test, and requires the goodwill impairment test to be performed by comparing the fair value of a reporting
unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair
value;  however,  the  loss  recognized  should  not  exceed  the  total  amount  of  goodwill  allocated  to  that  reporting  unit.  This  guidance  is  effective  for  the
Company in the first quarter of 2020. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January
1, 2017. In November 2019, the Company elected to early adopt ASU 2017-04, and the adoption had no impact on our consolidated financial statements.

Recent Accounting Guidance Not Yet Adopted

In  December  2019,  the  FASB  issued  ASU  2019-12,  Income  Taxes  (Topic  740):  Simplifying  the  Accounting  for  Income  Taxes,  as  part  of  its  overall
simplification initiative to reduce costs and complexity of applying accounting standards while maintaining or improving the usefulness of the information
provided to users of financial statements. The FASB’s amendments primarily impact ASC 740, Income Taxes,  and  may  impact  both  interim  and  annual
reporting periods. ASU 2019-12 will be effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years and
early adoption is permitted. We are currently evaluating the impact of adopting ASU 2019-12.

-66-

In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework— Changes to the Disclosure Requirement
for Fair Value Measurement” which amends certain disclosure requirements over Level 1, Level 2 and Level 3 fair value measurements. The amendments
in ASU 2018-13 are effective for fiscal years beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating the
impact of adopting ASU 2018-13 and does not believe the standard will have a material impact on the consolidated financial statements.

In  June  2016,  the  FASB  issued  ASU  No.  2016-13,  “Financial  Instruments  -  Credit  Losses  (Topic  326):  Measurement  of  Credit  Losses  on  Financial
Instruments (“ASU 2016-13”).” This standard requires entities to measure all expected credit losses for financial assets held at the reporting date based on
historical  experience,  current  conditions  and  reasonable  and  supportable  forecasts.  ASU  2016-13  will  be  effective  for  the  Company  for  fiscal  years
beginning on or after January 1, 2020, including interim periods within those annual reporting periods and early adoption is permitted. We are currently
evaluating the impact of our adoption of ASU 2016-13 on our condensed consolidated financial statements and currently does not believe the standard will
have a material impact on the consolidated financial statements.

NOTE 3: Subsidiary Bankruptcy and Deconsolidation

Bankruptcy Filing and Deconsolidation

As a result of Specialty Pharma’s bankruptcy filing on February 6, 2019, Avadel has ceded authority for managing the business to the Bankruptcy Court,
and  Avadel  management  cannot  carry  on  Specialty  Pharma’s  activities  in  the  ordinary  course  of  business  without  Bankruptcy  Court  approval.  Avadel
manages  the  day-to-day  operations  of  Specialty  Pharma,  but  does  not  have  discretion  to  make  significant  capital  or  operating  budgetary  changes  or
decisions and purchase or sell significant assets, as Specialty Pharma’s material decisions are subject to review by the Bankruptcy Court. For these reasons,
we have concluded that Avadel has lost control of Specialty Pharma, and no longer has significant influence over Specialty Pharma during the pendency of
the bankruptcy. Therefore, we deconsolidated Specialty Pharma effective with the filing of the Chapter 11 bankruptcy in February 2019.

In  order  to  deconsolidate  Specialty  Pharma,  the  carrying  values  of  the  assets  and  certain  liabilities  of  Specialty  Pharma  were  removed  from  our
consolidated balance sheet as of February 5, 2019, and we recorded our investment in Specialty Pharma at its estimated fair value of $0. As the estimated
fair  value  of  our  investment  in  Specialty  Pharma  was  lower  than  its  net  book  value  immediately  prior  to  the  deconsolidation,  we  recorded  a  non-cash
charge  of  approximately  $2,678  for  the  year  ended  December  31,  2019  associated  with  the  deconsolidation  of  Specialty  Pharma.  Subsequent  to  the
deconsolidation of Specialty Pharma, we are accounting for our investment in Specialty Pharma using the cost method of accounting because Avadel does
not exercise significant influence over the operations of Specialty Pharma due to the Chapter 11 filing.

On  April  26,  2019,  Specialty  Pharma  sold  its  intangible  assets  and  remaining  inventory  to  an  unaffiliated  third  party  in  exchange  for  aggregate  cash
proceeds of approximately $250, pursuant to an order approving such sale which was issued by the Bankruptcy Court on April 15, 2019. As a result of such
sale, Specialty Pharma has completed its divestment of the assets of the Noctiva business.

On  July  2,  2019,  Specialty  Pharma  was  made  aware  of  a  $50,695  claim  made  by  the  Internal  Revenue  Service  (IRS)  as  part  of  the  bankruptcy  claims
process against Specialty Pharma. On October 2, 2019 the IRS amended the original claim filed in July, reducing the claim to $9,302. Specialty Pharma
files its U.S. federal tax return as a member of the Company’s consolidated U.S. tax group. As such, the IRS claim was filed against Specialty Pharma in
the bankruptcy proceedings due to IRS tax law requirements for joint and several liability of all members in a consolidated U.S. tax group. Both Specialty
Pharma and the Company disagree with the merits of the amended IRS claim and intend to defend their positions vigorously.

Debtor in Possession (“DIP”) Financing – Related Party Relationship

In  connection  with  the  bankruptcy  filing,  Specialty  Pharma  entered  into  a  DIP  Credit  and  Security  Agreement  with  Avadel  US  Holdings  (“DIP  Credit
Agreement”) dated as of February 8, 2019, in an aggregate amount of up to $2,700, of which the funds are to be used by Specialty Pharma solely to fund
operations through February 6, 2020. As of December 31, 2019, the Company had funded $407 under the DIP Credit Agreement. As we have assessed that
it is unlikely that Specialty Pharma will pay back the loan to Avadel, the $407 has been recorded as part of the loss on deconsolidation of subsidiary within
the consolidated statements of (loss) income. At December 31, 2019, the fair value of the remaining commitment under the DIP Credit Agreement is not
material.

NOTE 4: Revenue Recognition

The Company generates revenue primarily from the sale of pharmaceutical products to customers. From time to time the Company also generates revenue
from licensing arrangements whereby the Company provides access to certain of its intellectual property.

-67-

Periods prior to January 1, 2018

Product Sales and Services

Revenue was generally realized or realizable and earned when persuasive evidence of an arrangement existed, delivery had occurred or services had been
rendered, the seller’s price to the buyer was fixed or determinable, and collectability was reasonably assured. The Company recorded revenue from product
sales  when  title  and  risk  of  ownership  transferred  to  the  customer,  which  was  typically  upon  delivery  to  the  customer  and  when  the  selling  price  was
determinable.

Licensing Revenues

From time to time, the Company enters into licensing agreements for the license of technology used for developing modified controlled release of oral
pharmaceutical products. Non-refundable fees where the Company had continuing performance obligations were deferred and recognized ratably over the
projected performance period. Milestone payments, which were typically related to regulatory, commercial or other achievements by the Company or their
licensees and distributors, were recognized as revenues when the milestone was accomplished and collection was reasonably assured.

Periods commencing January 1, 2018

Product Sales and Services

Effective January 1, 2018, the Company implemented ASC 606, Revenue From Contracts With Customers. The Company sells products primarily through
wholesalers  and  considers  these  wholesalers  to  be  its  customers.  Under  ASC  606,  revenue  from  product  sales  is  recognized  when  the  customer  obtains
control of the Company’s product and the Company’s performance obligations are met, which occurs typically upon receipt of delivery to the customer. As
is  customary  in  the  pharmaceutical  industry,  the  Company’s  gross  product  sales  are  subject  to  a  variety  of  price  deductions  in  arriving  at  reported  net
product  sales.  These  adjustments  include  estimates  for  product  returns,  chargebacks,  payment  discounts,  rebates,  and  other  sales  allowances  and  are
estimated when the product is delivered based on analysis of historical data for the product or comparable products, as well as future expectations for such
products.

Reserves to reduce Gross Revenues to Net Revenues

Revenues  from  product  sales  are  recorded  at  the  net  selling  price,  which  includes  estimated  reserves  to  reduce  gross  product  sales  to  net  product  sales
resulting from product returns, chargebacks, payment discounts, rebates, and other sales allowances that are offered within contracts between the Company
and its customers and end users. These reserves are based on the amounts earned or to be claimed on the related sales and are classified as reductions of
accounts  receivable  if  the  amount  is  payable  to  the  customer,  except  in  the  case  of  the  estimated  reserve  for  future  expired  product  returns,  which  are
classified as a liability. The reserves are classified as a liability if the amount is payable to a party other than a customer. Where appropriate, these estimated
reserves  take  into  consideration  relevant  factors  such  as  the  Company’s  historical  experience,  current  contractual  and  statutory  requirements,  specific
known market events and trends, industry data and forecasted customer buying and payment patterns. Overall, these reserves reflect the Company’s best
estimates to reduce gross selling price to net selling price to which it expects to be entitled based on the terms of its contracts. The actual net selling price
ultimately received may differ from the Company’s estimates. If actual results in the future vary from the Company’s estimates, the Company adjusts these
estimates, which would affect net product revenue and earnings in the period such variances become known.

Product Returns

Consistent  with  industry  practice  the  Company  maintains  a  returns  policy  that  generally  offers  customers  a  right  of  return  for  product  that  has  been
purchased from the Company. The Company estimates the amount of product returns and records this estimate as a reduction of revenue in the period the
related product revenue is recognized. The Company currently estimates product return liabilities based on analysis of historical data for the product or
comparable products, as well as future expectations for such products and other judgments and analysis.

Chargebacks, Discounts and Rebates

Chargebacks,  discounts  and  rebates  represent  the  estimated  obligations  resulting  from  contractual  commitments  to  sell  products  to  its  customers  or  end
users at prices lower than the list prices charged to our wholesale customers. Customers charge the Company for the difference between the gross selling
price they pay for the product and the ultimate contractual price agreed to between

-68-

the  Company  and  these  end  users.  These  reserves  are  established  in  the  same  period  that  the  related  revenue  is  recognized,  resulting  in  a  reduction  of
product revenue and accounts receivable. Chargebacks, discounts and rebates are estimated at the time of sale to the customer.

Revenue from licensing arrangements

The  terms  of  the  Company’s  licensing  agreements  may  contain  multiple  performance  obligations,  including  certain  R&D  activities.  The  terms  of  these
arrangements typically include payment to the Company of one or more of the following: non-refundable, up-front license fees; development, regulatory
and commercial milestone payments. Each of these payments are recorded as license revenues. The Company did not have any license revenue during the
year ended December 31, 2019.

License of Intellectual Property

If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, we
recognize revenues from non-refundable, up-front fees allocated to the license when the license is transferred to the customer and the customer is able to
use and benefit from the license. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined
performance  obligation  to  determine  whether  the  combined  performance  obligation  is  satisfied  over  time  or  at  a  point  in  time  and,  if  over  time,  the
appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, up-front fees. The Company evaluates the measure of
progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

Disaggregation of revenue

The  Company’s  primary  source  of  revenue  is  from  the  sale  of  pharmaceutical  products,  which  are  equally  affected  by  the  same  economic  factors  as  it
relates to the nature, amount, timing, and uncertainty of revenue and cash flows. For further detail about the Company’s revenues by product, see Note 22:
Company Operations by Product, Customer and Geography.

Contract Balances

The Company does not recognize revenue in advance of invoicing its customers and therefore has no related contract assets.

A receivable is recognized in the period the Company sells its products and when the Company’s right to consideration is unconditional.

There were no material deferred contract costs at December 31, 2019 and 2018.

Transaction Price Allocated to the Remaining Performance Obligation

For product sales, the Company generally satisfies its performance obligations within the same period the product is delivered. Product sales recognized in
2019 from performance obligations satisfied (or partially satisfied) in previous periods were immaterial.

For  certain  licenses  of  intellectual  property,  specifically  those  with  performance  obligations  satisfied  over  time,  the  Company  allocates  a  portion  of  the
transaction price to that performance obligation and recognizes revenue using an appropriate measure of progress towards development of the product. In
December 2018, we reached an agreement to exit a contract and our remaining performance obligations and recognized the remaining $1,600 of deferred
revenue,  which  represented  the  unsatisfied  performance  obligations  associated  with  a  license  agreement.  At  December  31,  2019,  the  deferred  revenue
balance related to this obligation is $0.

We have elected certain of the practical expedients from the disclosure requirement for remaining performance obligations for specific situations in which
an entity need not estimate variable consideration to recognize revenue. Accordingly, the Company applies the practical expedient in ASC 606 to its stand-
alone contracts and does not disclose information about variable consideration from remaining performance obligations for which we recognize revenue.

NOTE 5: Fair Value Measurements

The Company is required to measure certain assets and liabilities at fair value, either upon initial recognition or for subsequent accounting or reporting. For
example, we use fair value extensively when accounting for and reporting certain financial instruments, when measuring certain contingent consideration
liabilities and in the initial recognition of net assets acquired in a business combination. Fair value is estimated by applying the hierarchy described below,
which prioritizes the inputs used to measure fair

-69-

value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value
measurement.

ASC  820,  “Fair  Value  Measurements  and  Disclosures,”  defines  fair  value  as  a  market-based  measurement  that  should  be  determined  based  on  the
assumptions that marketplace participants would use in pricing an asset or liability. When estimating fair value, depending on the nature and complexity of
the asset or liability, we may generally use one or each of the following techniques: 

•

Income approach, which is based on the present value of a future stream of net cash flows.

• Market  approach,  which  is  based  on  market  prices  and  other  information  from  market  transactions  involving  identical  or  comparable  assets  or

liabilities.

As a basis for considering the assumptions used in these techniques, the standard establishes a three-tier fair value hierarchy which prioritizes the inputs
used in measuring fair value as follows:  

•

•

•

Level 1 - Quoted prices for identical assets or liabilities in active markets.

Level 2 - Quoted prices for similar assets or liabilities in active markets, or quoted prices for identical or similar assets or liabilities in markets that
are  not  active,  or  inputs  other  than  quoted  prices  that  are  directly  or  indirectly  observable,  or  inputs  that  are  derived  principally  from,  or
corroborated by, observable market data by correlation or other means.

Level 3 - Unobservable inputs that reflect estimates and assumptions.

The following table summarizes the financial instruments measured at fair value on a recurring basis classified in the fair value hierarchy (Level 1, 2 or 3)
based on the inputs used for valuation in the accompanying consolidated balance sheets:

A  review  of  fair  value  hierarchy  classifications  is  conducted  on  a  quarterly  basis.    Changes  in  the  observability  of  valuation  inputs  may  result  in  a
reclassification for certain financial assets or liabilities. During the fiscal year ended December 31, 2019, there were no transfers in and out of Level 1, 2, or
3. During the twelve months ended December 31, 2019, 2018 and 2017, we did not recognize any other-than-temporary impairment loss.

Some of the Company’s financial instruments, such as cash and cash equivalents, accounts receivable and accounts payable, are reflected in the balance
sheet at carrying value, which approximates fair value due to their short-term nature.

Debt

We estimate the fair value of our $143,750 aggregate principal amount of 4.50% exchangeable senior notes due 2023 (the “2023 Notes”), a Level 2 input,
based on interest rates that would be currently available to the Company for issuance of similar types of debt instruments with similar terms and remaining
maturities or recent trading prices obtained from brokers. The estimated fair value of the 2023 Notes at December 31, 2019 is $107,692 compared to a book
value of $121,686.

See Note 11: Long-Term Debt for additional information regarding our debt obligations.

NOTE 6: Marketable Securities 

We have investments in available-for-sale marketable securities which are recorded at fair market value. Prior to January 1, 2018, unrealized gains and
losses on all securities are recorded as other comprehensive income (loss) in shareholders’ equity, net of income tax effects.

On  January  1,  2018,  the  Company  adopted  ASU  2016-01,  which  requires  the  change  in  the  fair  value  of  available-for-sale  equity  investments  to  be
recognized in our consolidated statements of (loss) income rather than as a component of our consolidated statement of comprehensive (loss) income. For
the years ended December 31, 2019 and 2018, the net unrealized loss on our available-for-sale equity investments, recorded as a component of investment
income in the accompanying consolidated statements of (loss) income, was income of $170 and a loss of $956, respectively. The net unrealized gain on our
available-for-sale  equity  investments  was  immaterial  for  the  year  ended  December  31,  2017  and  was  recorded  as  other  comprehensive  income  in
shareholders’ equity, net of income tax effects.

The  following  tables  show  the  Company’s  available-for-sale  securities’  adjusted  cost,  gross  unrealized  gains,  gross  unrealized  losses  and  fair  value  by

$317, and $1,677 for the twelve months ended December 31, 2019, 2018, and 2017, respectively. These realized gains were offset by realized losses of
$151, $565, and $1,390 for the twelve-months ended December 31, 2019, 2018, and 2017, respectively. We reflect these gains and losses as a component of

The Company recorded amortization expense related to amortizable intangible assets of $816, $6,619 and $3,659 for the years ended December 31, 2019,
2018 and 2017, respectively.  

No impairment loss related to goodwill or intangible assets was recognized during the year ended December 31, 2019.

During the fourth quarter 2018, certain conditions came to light, largely the lack of a meaningful increase in Noctiva prescriptions despite the substantial
investment of resources, which indicated that the carrying value of the asset, may not be fully recoverable. As such, we performed an impairment test based
on a comparison of the pretax discounted cash flows expected to be generated by the asset, which is a Level 3 fair value estimate, to the recorded value of
the asset and concluded that the associated cash flows did not support any of the carrying value of the intangible asset and we recorded a full impairment
charge  of  $66,087  at  December  31,  2018  related  to  the  acquired  developed  technology  associated  with  Noctiva.  The  Chapter  11  bankruptcy  filing  of
Specialty Pharma commenced on February 6, 2019, the subsidiary which marketed, sold and distributed Noctiva, confirmed management’s conclusion on
the impairment. This impairment charge is included in the line “Impairment of intangible asset” in the consolidated statements of (loss) income.

Amortizable intangible assets are amortized over their estimated useful lives, which range from three to fifteen years, using the straight-line method. At
December 31, 2019, total amortization of intangible assets for the year ended December 31, 2020 is $813. There is no estimated amortization during the
years ended December 31, 2021-2024 as the acquired developed technology - Vazculep will be fully amortized at December 31, 2020.

NOTE 10: Leases

On January 1, 2019, the Company adopted the ASU 842 using the modified retrospective transition approach and elected the transition option to recognize
the adjustment in the period of adoption rather than in the earliest period presented. The adoption resulted in the initial recognition of operating lease right-
of-use assets of $5,046 and operating lease liabilities of $5,131.  At  December  31,  2019,  the  balances  of  the  operating  lease  right-of-use  asset  and  total
operating lease liability were $3,612 and $2,964, respectively, of which $645 of the operating lease liability is classified as a current liability.

The Company leases certain office facilities, comprising approximately 81% of the total lease population at December 31, 2019. All leased facilities are
classified as operating leases with remaining lease terms between one and five years. The Company determines if a contract is a lease at the inception of the
arrangement. The Company reviews all options to extend, terminate, or purchase its right-of-use assets at the inception of the lease and will include these
options  in  the  lease  term  when  they  are  reasonably  certain  of  being  exercised.  For  all  of  the  Company’s  leases,  lease  and  non-lease  components  are
accounted for as a single lease component, as all non-lease components are immaterial to break out separately.

The components of lease costs, which are included in selling, general and administrative expenses in the consolidated statements of (loss) income of year
ended December 31, 2019 were as follows:

Lease cost:

Operating lease costs (1)

Sublease income (2)

(1) Variable lease costs were immaterial for the year ended December 31, 2019.
(2)  Represents  sublease  income  received  for  the  vacated  office  facility  in  Charlotte,  North  Carolina,  which  was  acquired  with  the  FSC  acquisition  in
February  2016.  The  lease  and  sublease  agreements  terminate  in  December  2020.  The  Company  also  vacated  portions  of  its  office  facility  in  St.  Louis,
Missouri during May 2019 and August 2019 and started receiving sublease income starting in May 2019 and August 2019 from two different tenants. The
lease  agreement  ends  in  April  2025  and  the  sublease  agreement  that  started  in  May  2019  ends  in  May  2021  and  the  sublease  agreement  that  started  in
August 2019 ends in July 2020 and can continue thereafter on a month-to-month basis.

During the year ended December 31, 2019, the Company reduced its operating lease liabilities by $1,480 for cash paid. The remainder of the decrease is
related to the exit of certain leases discussed below. In addition, during the year ended December 31, 2019, one new operating lease commenced resulting
in the recognition of an operating lease right-of-use asset and liability of $1,000 and $0, respectively, as the entire lease payment was paid on March 31,
2019. As of December 31, 2019, the Company is aware of one additional potential embedded lease that has not yet commenced and will not commence
until certain conditions are

-73-

 
 
met. If these conditions are met and the start date is determined, annual fees would commence and at that time an operating lease right-of-use asset and
corresponding operating lease liability will be recorded.

In  connection  with  the  2019  Corporate  Restructuring  plan  discussed  in  Note  18:  Restructuring  Costs,  during  the  year  ended  December  31,  2019,  the
Company  came  to  an  agreement  with  the  landlord  of  the  leased  office  space  in  Ireland,  to  surrender  the  lease  by  December  31,  2019  with  an  early
termination payment of approximately $288. This amount was recorded as a restructuring cost in the consolidated statements of (loss) income.

In connection with the 2019 French Restructuring plan discussed in Note 18: Restructuring Costs, during the year ended December 31, 2019, the Company
came  to  an  agreement  with  the  landlord  of  the  leased  office  space  in  France,  to  surrender  the  lease  by  December  31,  2019  with  an  early  termination
payment  of  approximately  $820. The  Company  accounted  for  this  change  in  the  lease  term  as  a  modification  of  the  original  lease.  As  a  result  of  this
modification, the right-of-use asset and liability related to the French office lease was remeasured, and the asset was subsequently tested for impairment as
the fair value was less than the book value. Since the fair value was determined to be less than the book value, the Company recorded an impairment to the
right of use asset of $826, which is recorded as a restructuring cost in the consolidated statements of loss.

As of December 31, 2019, our operating leases have a weighted-average remaining lease term of 5.0 years and a weighted-average discount rate of 5.3%.
Nearly all of Avadel’s lease contracts do not provide a readily determinable implicit rate. For these contracts, Avadel’s estimated incremental borrowing
rate is based on information available at the inception of the lease.

On February 16, 2018, Avadel Finance Cayman Limited, a Cayman Islands exempted company (the “Issuer”) and an indirect wholly-owned subsidiary of
the Company, issued $125,000 aggregate principal amount of 4.50% exchangeable senior notes due 2023 (the “2023 Notes”) in a private placement (the
“Offering”) to qualified institutional buyers pursuant to Rule 144A under the Securities Act. In connection with the Offering, the Issuer granted the initial
purchasers  of  the  2023  Notes  a  30-day  option  to  purchase  up  to  an  additional  $18,750  aggregate  principal  amount  of  the  2023  Notes,  which  was  fully
exercised on February 16, 2018. Net proceeds received by the Company, after issuance costs and discounts, were approximately $137,560.

The Company pays 4.50% cash interest per year on the principal amount of the 2023 Notes, payable semi-annually in arrears on February 1 and August 1
of  each  year,  beginning  on  August  1,  2018,  to  holders  of  record  at  the  close  of  business  on  the  preceding  January  15  or  July  15,  respectively.  Interest
accrues on the principal amount of the 2023 Notes from and including the date the 2023 Notes were issued or from, and including, the last date in respect
of  which  interest  has  been  paid  or  provided  for,  as  the  case  may  be,  to,  but  excluding,  the  next  interest  payment  date.  The  2023  Notes  are  general,
unsecured  obligations  of  the  Issuer,  and  are  fully  and  unconditionally  guaranteed  by  the  Company  on  a  senior  unsecured  basis.  There  are  no  financial
debt covenants associated with the 2023 Notes. 

The 2023 Notes are the Company’s senior unsecured obligations and rank equally in right of payment with all of the Company’s existing and future senior
unsecured indebtedness and effectively junior to any of the Company’s existing and future secured indebtedness, to the extent of the value of the assets
securing such indebtedness.

The 2023 Notes will be exchangeable at the option of the holders at an initial exchange rate of 92.6956 ADSs per $1 principal amount of 2023 Notes,
which is equivalent to an initial exchange price of approximately $10.79 per ADS. Such initial exchange price represents a premium of approximately 20%
to the $8.99 per ADS closing price on The Nasdaq Global Market on February 13, 2018.  Upon the exchange of any 2023 Notes, the Issuer will pay or
cause to be delivered, as the case may be, cash, ADSs or a combination of cash and ADSs, at the Issuer’s election. Holders of the 2023 Notes may convert
their 2023 Notes, at their option, only under the following circumstances prior to the close of business on the business day immediately preceding August
1, 2022, under the circumstances and during the periods set forth below and regardless of the conditions described below, on or after August 1, 2022 and
prior to the close of business on the business day immediately preceding the maturity date:

•

•

Prior to the close of business on the business day immediately preceding August 1, 2022, a holder of the 2023 Notes may surrender all or any
portion of its 2023 Notes for exchange at any time during the five business day period immediately after any five consecutive trading day period
(the “Measurement Period”) in which the trading price per $1 principal amount of 2023 Notes, as determined following a request by a holder of
the 2023 Notes, for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the ADSs and
the exchange rate on each such trading day.

If a transaction or event that constitutes a fundamental change or a make-whole fundamental change occurs prior to the close of business on the
business day immediately preceding August 1, 2022, regardless of whether a holder of the 2023 Notes has the right to require the Company to
repurchase the 2023 Notes, or if Avadel is a party to a merger event that

-75-

 
 
 
 
 
 
 
 
 
   
   
   
   
occurs prior to the close of business on the business day immediately preceding August 1, 2022, all or any portion of a the holder’s 2023 Notes
may be surrendered for exchange at any time from or after the date that is 95 scheduled trading days prior to the anticipated effective date of the
transaction (or, if later, the earlier of (x) the business day after the Company gives notice of such transaction and (y) the actual effective date of
such  transaction)  until  35  trading  days  after  the  actual  effective  date  of  such  transaction  or,  if  such  transaction  also  constitutes  a  fundamental
change, until the related fundamental change repurchase date. 

•

•

Prior to the close of business on the business day immediately preceding August 1, 2022, a holder of the 2023 Notes may surrender all or any
portion of its 2023 Notes for exchange at any time during any calendar quarter commencing after the calendar quarter ending on June 30, 2018
(and only during such calendar quarter), if the last reported sale price of the ADSs for at least 20 trading days (whether or not consecutive) during
the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater
than or equal to 130% of the exchange price on each applicable trading day. 

If  the  Company  calls  the  2023  Notes  for  redemption  pursuant  to  Article  16  to  the  Indenture  prior  to  the  close  of  business  on  the  business  day
immediately preceding August 1, 2022, then a holder of the 2023 Notes may surrender all or any portion of its 2023 Notes for exchange at any
time prior to the close of business on the second business day prior to the redemption date, even if the 2023 Notes are not otherwise exchangeable
at such time. After that time, the right to exchange shall expire, unless the Company defaults in the payment of the redemption price, in which case
a holder of the 2023 Notes may exchange its 2023 Notes until the redemption price has been paid or duly provided for.

We considered the guidance in ASC 815-15, Embedded Derivatives, to determine if this instrument contains an embedded feature that should be separately
accounted for as a derivative. ASC 815 provides for an exception to this rule when convertible notes, as host instruments, are deemed to be conventional, as
defined by ASC 815-40. We determined that this exception applies due, in part, to our ability to settle the 2023 Notes in cash, ADSs or a combination of
cash and ADSs, at our option. We have therefore applied the guidance provided by ASC 470-20, Debt with Conversion and Other Options which requires
that  the  2023  Notes  be  separated  into  debt  and  equity  components  at  issuance  and  a  value  be  assigned  to  each.  The  carrying  amount  of  the  liability
component  was  calculated  by  measuring  the  fair  value  of  a  similar  liability  that  does  not  have  an  associated  convertible  feature.  The  allocation  was
performed in a manner that reflected our non-convertible debt borrowing rate for similar debt. The equity component of the 2023 Notes was recognized as
a debt discount and represents the difference between the proceeds from the issuance of the 2023 Notes and the fair value of the liability of the 2023 Notes
on its issuance date. The excess of the principal amount of the liability component over its carrying amount (the “Debt Discount”) is amortized to interest
expense using the effective interest method over the term of the 2023 Notes. The equity component is not remeasured as long as it continues to meet the
conditions for equity classification.

In connection with the issuance of the 2023 Notes, we incurred approximately $6,190 of debt issuance costs, which primarily consisted of underwriting,
legal  and  other  professional  fees,  and  allocated  these  costs  to  the  liability  and  equity  components  based  on  the  allocation  of  the  proceeds.  Of  the  total
$6,190 of debt issuance costs, $1,201 were allocated to the equity component and recorded as a reduction to additional paid-in capital and $4,989 were
allocated to the liability component and recorded as a reduction to debt on our consolidated balance sheets. The portion allocated to the liability component
is amortized to interest expense using the effective interest method over the same five-year term as the related 2023 Notes.

Each of the above items is associated with related parties as further described in Note 23: Related Party Transactions. 

(a)

In  March  2012,  the  Company  acquired  all  of  the  membership  interests  of  Éclat  from  Breaking  Stick  Holdings,  L.L.C.  (“Breaking  Stick”,  formerly
Éclat Holdings), an affiliate of Deerfield. Breaking Stick is majority owned by Deerfield, with a minority interest owned by certain current and former
employees. As part of the consideration, the Company committed to provide quarterly earn-out payments equal to 20% of any gross profit generated
by certain Éclat products. These payments will continue in perpetuity, to the extent gross profit of the related products also continue in perpetuity.

(b) As part of a February 2013 debt financing transaction conducted with Deerfield, the Company received cash of $2,600 in exchange for entering into a
royalty agreement whereby the Company shall pay quarterly a 1.75% royalty on the net sales of certain Éclat products until December 31, 2024. In
connection  with  such  debt  financing  transaction,  the  Company  granted  Deerfield  a  security  interest  in  the  product  registration  rights  of  the  Éclat
Pharmaceuticals products.

(c) As part of a December 2013 debt financing transaction conducted with Broadfin Healthcare Master Fund, a related party and current shareholder, the
Company received cash of $2,200 in exchange for entering into a royalty agreement whereby the Company shall pay quarterly a 0.834% royalty on the
net sales of certain Éclat products until December 31, 2024.

At December 31, 2019, the fair value of each related party payable listed in (a), (b) and (c) above was estimated using a discounted cash flow model based
on estimated and projected annual net revenues or gross profit, as appropriate, of each of the specified Éclat products using an appropriate risk-adjusted
discount rate of 14%. These fair value measurements are based on significant inputs not observable in the market and thus represent a level 3 measurement
as  defined  in  ASC  820.  Subsequent  changes  in  the  fair  value  of  the  acquisition-related  related  party  payables,  resulting  primarily  from  management’s
revision of key assumptions, will be recorded in the consolidated statements of (loss) income in the line items entitled “Changes in fair value of related
party contingent consideration” for items noted in (b) above and in “Other (expense) income - changes in fair value of related party payable” for items (b)
and (c) above. See Note 1:  Summary  of  Significant  Accounting  Policies  under  the  caption  Acquisition-related  Contingent  Consideration  and  Financing-
related Royalty Agreements for more information on key assumptions used to determine the fair value of these liabilities. 

We have chosen to make a fair value election pursuant to ASC 825, “Financial Instruments” for its royalty agreements detailed in items (b) and (c) above.
These  financing-related  liabilities  are  recorded  at  fair  market  value  on  the  consolidated  balance  sheets  and  the  periodic  change  in  fair  market  value  is
recorded as a component of “Other (expense) income – changes in fair value of related party payable” on the consolidated statements of (loss) income.

In 2019, the income tax benefit decreased by $12,537 when compared to the same period in 2018. The decrease in the income tax benefit in 2019 was
primarily driven by the impairment of the Noctiva intangible asset in 2018, which did not recur in 2019. In addition to the non-recurring impairment, an
increase in the valuation allowance in 2019, when compared to the same period in 2018 also contributed to the decrease in tax benefit recorded in 2019. As
a part of a corporate reorganization, the Company entered into an internal sale transaction in December 2019. The internal sale transaction included transfer
of  intangible  assets  from  an  Irish  entity  to  a  U.S.  entity.  The  internal  sale  transaction  resulted  in  a  decrease  of  $5,536  to  Irish  deferred  tax  asset  with
corresponding decrease of $5,536 to valuation allowance, an increase of $8,190 to U.S. deferred tax asset associated with amortization of intangible assets,
and a $8,190 deferred tax benefit.

In 2018, the income tax provision decreased by $42,282 when compared to the same period in 2017, resulting in an income tax benefit. The decrease in the
income  tax  provision  was  primarily  driven  by  a  significant  reduction  in  the  amount  of  taxable  income  recorded  in  the  U.S.  and  Ireland  in  2018,  when
compared to 2017. There was also a significant increase in valuation allowance in 2018, when compared to the same period in 2017 as a result of this. In
2018, there was a significant decrease in amounts related to change in U.S. tax law due to the 2017 U.S. Tax Cuts and Jobs Act.

Unrecognized Tax Benefits

The Company or one of its subsidiaries files income tax returns in Ireland, France, U.S. and various states. The Company is no longer subject to Irish,
French,  U.S.  Federal,  and  state  and  local  examinations  for  years  before  2015.  The  Internal  Revenue  Service  (IRS)  commenced  an  examination  of  the
Company's U.S. income tax return for 2015 in the 4th quarter of 2016. In the second

quarter of 2019, the IRS added the 2016 and 2017 U.S. income tax return to the ongoing 2015 audit. The French tax authority commenced an examination
of the Company's French tax return for 2017 in the first quarter of 2019.

We expect that within the next twelve months the unrecognized tax benefits could decrease by $2,000 - $3,000. Additionally, interest could increase by up
to $400.

At December  31,  2019,  2018,  and  2017,  there  are  $3,806, $4,597,  and  $3,349  of  unrecognized  tax  benefits  that  if  recognized  would  affect  the  annual
effective tax rate.

We recognize interest and penalties accrued related to unrecognized tax benefits in income tax expense. During the years ended December 31, 2019, 2018,
and  2017,  we  recognized  approximately  $555, $725,  and  $304  in  interest  and  penalties.  We  had  approximately  $1,612,  and  $1,057  for  the  payment  of
interest and penalties accrued at December 31, 2019, and 2018, respectively.

Deferred Tax Assets (Liabilities) 

Deferred  income  tax  provisions  reflect  the  effect  of  temporary  differences  between  consolidated  financial  statement  and  tax  reporting  of  income  and
expense items. The net deferred tax assets/liabilities at December 31, 2019 and 2018 resulted from the following temporary differences:

At December 31, 2019, we had $95,771 of net operating losses in Ireland that do not have an expiration date and $75,537 of net operating loss in the U.S.
Of the $75,537 of net operating loss in the U.S., $10,365 were acquired due to the acquisition of FSC and $65,172 is due to the losses at US Holdings.  The
portion due to the acquisition of FSC will expire in 2034 through 2035.  A valuation allowance is recorded if, based on the weight of available evidence, it
is more likely than not that a deferred tax asset

will not be realized. This assessment is based on an evaluation of the level of historical taxable income and projections for future taxable income. For the
year ended December 31, 2019 we recorded $13,320 of valuation allowances related to Irish net operating losses and $309 of valuation allowances related
to the U.S. net operating losses. The U.S. net operating losses are subject to an annual limitation as a result of the FSC acquisition under Internal Revenue
Code Section 382 and will not be fully utilized before they expire.

We recorded a valuation allowance against all of our net operating losses in Ireland as of December 31, 2019, and all of our net operating losses in Ireland
and France as of December 31, 2018. We intend to continue maintaining a full valuation allowance on the Irish net operating losses until there is sufficient
evidence  to  support  the  reversal  of  all  or  some  portion  of  these  allowances.  In  2019,  we  removed  $3,259  of  French  net  operating  losses  and  the
corresponding valuation allowance as a result of the 2019 restructuring activities in France. See Note 18: Restructuring Costs.

While we believe it is more likely than not that it will be able to realize the deferred tax assets in the U.S., we continue to monitor changes in the U.S.
hospital  products  market  as  unfavorable  changes  could  ultimately  impact  our  assessment  of  the  realizability  of  our  U.S.  deferred  tax  assets.  If  we
experience an ownership change under Internal Revenue Code Section 382, the U.S. net operating losses could also be limited in their utilization.

At December 31, 2019, we have unremitted earnings of $3,961 outside of Ireland as measured on a U.S. GAAP basis. Whereas the measure of earnings for
purposes of taxation of a distribution may be different for tax purposes, these earnings, which are considered to be invested indefinitely, would become
subject to income tax if they were remitted as dividends or if we were to sell our stock in the subsidiaries, net of any prior income taxes paid. It is not
practicable to estimate the amount of deferred tax liability on such earnings, if any.

Research and Development Tax Credits Receivable 

The  French  and  Irish  governments  provide  tax  credits  to  companies  for  spending  on  innovative  R&D.  These  credits  are  recorded  as  an  offset  of  R&D
expenses and are credited against income taxes payable in years after being incurred or, if not so utilized, are recoverable in cash after a specified period of
time,  which  may  differ  depending  on  the  tax  credit  regime.  As  of  December  31,  2019,  our  net  research  tax  credit  receivable  amounts  to  $8,429  and
represents a French gross research tax credit of $7,608 and an Irish gross research tax credit of $821. As of December 31, 2018, our net Research tax credit
receivable amounts to $7,555 and represents a French gross research tax credit of $6,922 and an Irish gross research tax credit of $633.

Income Tax Deferred Charge 

On December 16, 2014, we transferred all of our intangible intellectual property from our French entity to our Irish entity as part of a global reorganization.
The  intellectual  property  includes  patents  on  drug  delivery  platforms,  clinical  data  sets  and  other  intangible  assets  related  to  the  pipeline  of  proprietary
products in development. This intra-entity transaction resulted in a charge of $14,088 of related taxes to the French government in December 2014. As this
represents an intra-entity transaction, no deferred tax asset was originally recognized, but rather was recorded as $986 of prepaid expenses and $13,102 of a
long-term income tax deferred charge asset in accordance with ASC 740-10-25-3 (e). This income tax deferred charge asset is amortized over the tax life of
the  asset  at  a  rate  of  7%  per  year  and  will  result  in  tax  relief  in  Ireland  of  $8,500  from  2016  to  2029,  subject  to  the  ability  to  realize  tax  benefits  for
additional deductions. At December 31, 2016, the balance of these respective accounts was classified as prepaid expenses of $814 and income tax deferred
charge asset of $10,342. In 2017, we adopted the provisions of ASU 2016-16, related to Intra-Entity Transfers of Assets Other Than Inventory. Adoption of
ASU 2016-16 eliminated the $11,156 income tax deferred charge recorded within the consolidated balance sheet as of December 31, 2016. In addition to
the  elimination  of  the  income  tax  deferred  charge,  we  recorded  a  deferred  tax  asset  of  $7,954  related  to  the  remaining  unamortized  tax  basis  of  the
intangible intellectual property. A full valuation allowance was recorded against the deferred tax asset as sufficient evidence does not exist at this time that
we will be able to utilize these benefits.

2017 Tax Cuts and Jobs Act

On December 22, 2017, the U.S. government enacted the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act includes significant changes to the U.S.
corporate  income  tax  system  including:  a  federal  corporate  rate  reduction  from  35%  to  21%;  limitations  on  the  deductibility  of  interest  expense  and
executive compensation; creation of the base erosion anti-abuse tax (“BEAT”) and a new minimum tax.  As a result of the Act being signed into law, we
recognized a provisional charge of $274 and $3,513 in 2018 and 2017, respectively, related to the re-measurement of its U.S. net deferred tax assets and
certain unrecognized tax benefits at the lower enacted corporate tax rates. A majority of the provisions in the Tax Act were effective January 1, 2018.

NOTE 14: Post-Retirement Benefit Plans 

Post-Retirement Benefit Contributions to French Government Agencies 

The Company is required by French law for our French employees to deduct specific monthly payroll amounts to support post-retirement benefit programs
sponsored  by  the  relevant  government  agencies  in  France.  As  the  ultimate  obligation  is  maintained  by  the  French  government  agencies,  there  is  no
additional liability recorded by the Company in connection with this plan. Expenses recognized for this plan were $288 in 2019, $356 in 2018, and $606 in
2017. 

Retirement Indemnity Obligation – France 

French law requires the Company to provide for the payment of a lump sum retirement indemnity to French employees based upon years of service and
compensation at retirement. The retirement indemnity has been actuarially calculated on the assumption of voluntary retirement at a government-defined
retirement age. Benefits do not vest prior to retirement. Any actuarial gains or losses are recognized in the Company’s consolidated statements of (loss)
income in the periods in which they occur. 

During the second quarter of 2019, the Company initiated a plan to substantially reduce all of its workforce at its Vénissieux, France site (“2019 French
Restructuring”). As a result of this decision, the Company reversed the French retirement indemnity obligation during the year ended December 31, 2019.
See Note 18: Restructuring Costs.

The  benefit  obligation  is  calculated  as  the  present  value  of  estimated  future  benefits  to  be  paid,  using  the  following  assumptions  for  the  years  ended
December 31: 

Retirement Benefit Obligation Assumptions:

2018

2017

Compensation rate increase

Discount rate

Employee turn-over

Average age of retirement

2.75%  

1.50%  

3.00%

1.25%

Actuarial standard and average of the last 5 years

60 to 65 years actuarial standard based on age and professional status

Certain actuarial assumptions, such as discount rate, have a significant effect on the amounts reported for net periodic benefit cost and accrued retirement
indemnity  benefit  obligation  amounts.  The  discount  rate  is  determined  annually  by  benchmarking  a  published  long-term  bond  index  using  the  iBoxx  €
Corporates AA 10+ index.

The lump sum retirement indemnity was accrued at December 31, 2018 on the Company’s consolidated balance sheets within non-current other liabilities,
excluding the current portion. As these are not funded benefit plans, there are no respective assets recorded. 

Due  to  the  2019  French  Restructuring  plan,  at  December  31,  2019  there  are  no  future  expected  retirement  indemnity  benefits  to  be  paid.  See Note  18:

The Company is subject to potential liabilities generally incidental to our business arising out of present and future lawsuits and claims related to product
liability,  personal  injury,  contract,  commercial,  intellectual  property,  tax,  employment,  compliance  and  other  matters  that  arise  in  the  ordinary  course  of
business. The Company accrues for potential liabilities when it is probable that future costs (including legal fees and expenses) will be incurred and such
costs  can  be  reasonably  estimated.  At  December  31,  2019  and  December  31,  2018,  there  were  no  contingent  liabilities  with  respect  to  any  litigation,
arbitration or administrative or

other proceeding that are reasonably likely to have a material adverse effect on the Company’s consolidated financial position, results of operations, cash
flows or liquidity.  

Note 3: Subsidiary Bankruptcy and Deconsolidation briefly describes the Chapter 11 bankruptcy case which our subsidiary Specialty Pharma commenced
on  February  6,  2019,  and  which  on  April  26,  2019  resulted  in  the  bankruptcy  court-approved  sale  of  all  of  Specialty  Pharma’s  intangible  assets  and
inventory  to  an  unaffiliated  third  party.  As  a  result  of  such  sale,  Specialty  Pharma  has  completed  its  divestment  of  the  assets  of  the  Noctiva  business.
During  the  pendency  of  the  bankruptcy  case,  all  pending  litigation  against  Specialty  Pharma  is  automatically  stayed  and  any  new  litigation  against
Specialty Pharma is precluded unless the bankruptcy court orders otherwise. Below are descriptions of a litigation to which Specialty Pharma is a party and
a contract dispute involving Specialty Pharma, both of which matters are subject to the automatic stay during the bankruptcy case.

Ferring  Litigation.  Some  of  the  patents  covering  the  Noctiva  product  (the  “Noctiva  Patents”)  are  the  subject  of  litigation  initiated  by  Ferring
Pharmaceuticals Inc. and two of its foreign affiliates, who manufacture a competing product known as Nocdurna.  Nocdurna was approved by the FDA in
June 2018 and commercially launched in the U.S. in November 2018.  In this litigation, filed in the United States District Court for the Southern District of
New York, Ferring seeks to invalidate and disputes the inventorship of the Noctiva Patents, seeks damages for various alleged breaches of contractual and
common  law  duties,  and  seeks  damages  for  alleged  infringement  by  Noctiva  of  Ferring’s  “Nocdurna”  trademark.    Specialty  Pharma  and  certain  other
parties  including  Serenity  Pharmaceuticals,  LLC  (“Serenity”)  (the  licensor  of  the  Noctiva  Patents)  have  defended  this  litigation,  and  have  made
counterclaims against Ferring, including for infringement of the Noctiva Patents and a declaratory judgment of noninfringement with respect to Ferring’s
“Nocdurna”  trademark.  The  court  dismissed  Ferring’s  inventorship  claim  and  its  claims  for  alleged  breaches  of  contractual  and  common  law  duties,
although these dismissals may be appealed by Ferring.  On February 15, 2019, Specialty Pharma and its co-defendants moved to stay the litigation pending
completion of the bankruptcy proceeding of Specialty Pharma. On May 15, 2019, that motion was denied due to a pending settlement of the litigation with
respect  to  just  Ferring  and  Specialty  Pharma.  On  February  25,  2020,  Ferring  and  Specialty  Pharma  jointly  moved  for  bankruptcy  court  approval  of  a
settlement agreement with respect to the claims alleged in the litigation.  In accordance with the terms of the settlement agreement, promptly following
bankruptcy court approval of the settlement agreement, the parties would dismiss with prejudice their respective claims against each other in the litigation. 
On March 13th, 2020, the bankruptcy court entered an order approving the settlement with Ferring.  Pursuant to the terms of the settlement, the parties are
to  dismiss  their  respective  claims  against  each  other  in  the  District  Court  litigation  in  the  Southern  District  of  New  York,  with  such  dismissals  to  be
effective concurrently.  That joint dismissal has not yet been filed with District Court for the Southern District of New York.

Contract Dispute. On January 21, 2019, Serenity gave notice to Specialty Pharma of an alleged breach of the parties’ Noctiva license agreement. Serenity
alleges that Specialty Pharma breached its contractual obligation to devote commercially reasonable efforts to the commercialization of Noctiva and seeks
unspecified damages. On January 27, 2019, Specialty Pharma notified Serenity of a claim for $1.7 million in damages as a result of Serenity’s breach of its
contractual  obligation  to  pay  the  costs  of  the  Ferring  Litigation.  Serenity’s  notice  to  Specialty  Pharma  invoked  the  dispute  resolution  provisions  of  the
Noctiva license agreement, which culminate in arbitration, but neither party has yet initiated an arbitration proceeding or filed suit.

Exela Litigation.  On January 7, 2020, Exela filed a complaint against us and our subsidiary, Avadel Legacy in the United States District for the District of
Delaware. The complaint alleges infringement of a certain Exela patent related to its cysteine hydrochloride product. Exela is most notably seeking i) a
declaratory judgment that the Nouress product infringes its patent, ii) an injunction (both preliminary and permanent) precluding the launch of Nouress, and
iii) monetary damages (including enhanced damages, prejudgment interest and attorneys’ fees) in the event Nouress is commercially launched and found to
infringe Exela’s patent.  We have not yet been served with the complaint.

Former employee dispute. On January 10, 2020, we settled a dispute with a former employee for $1,750.

Material Commitments  

At December 31, 2019, we have various commitments to purchase finished product from customers. For the year ended December 31, 2019, the Company
paid $7,400 related to the below purchase commitments. Commitments for these arrangements, at maximum quantities and at contractual prices over the
remaining life of the contract, and excluding any waived commitments, are as follows for the years ended December 31:

The  Company  also  has  a  commitment  with  a  contract  manufacturer  related  to  the  construction  and  preparation  of  a  production  suite  at  the  contract
manufacturer’s facility, which is substantially complete at December 31, 2019. Subsequent to the initial build and preparation of the production suite, this
commitment also includes annual fees which would commence at the time of FDA approval of the product and continue thereafter for five years. These
amounts are not included in the table above, as the start date has not been determined.

Leases    

The  Company  and  our  subsidiaries  lease  office  facilities  under  non-cancellable  operating  leases  expiring  at  various  dates.  See  Note  10:  Leases  for
disclosure of these.

Other  than  the  above  commitments,  there  were  no  other  material  commitments  outside  of  the  normal  course  of  business.  Material  commitments  in  the
normal course of business include long-term debt and long-term related party payable, which are disclosed in Note 11: Long-Term Debt and Note 12: Long-
Term Related Party Payable, respectively.

NOTE 17: Divestiture of the Pediatric Assets

On February 12, 2018, the Company, together with its subsidiaries Avadel Pharmaceuticals (USA), Inc., Avadel Pediatrics, Inc., FSC Therapeutics, LLC
(“FSC Therapeutics”), and Avadel US Holdings, Inc. (“Holdings”), as the “Sellers,” entered into an asset purchase agreement (the “Purchase Agreement”)
with Cerecor, Inc. (“Cerecor”). The transaction closed on February 16, 2018 wherein Cerecor purchased from the Sellers four pediatric commercial stage
assets – Karbinal™ ER, Cefaclor, Flexichamber™ and AcipHex® Sprinkle™, together with certain associated business assets – which were held by FSC. 
The  Company  acquired  FSC  in  February  2016  from  Deerfield  and  certain  of  its  affiliates.  Pursuant  to  the  Purchase  Agreement,  Cerecor  assumed  the
Company’s    remaining  payment  obligations  to  Deerfield  under  the  Membership  Interest  Purchase  Agreement,  dated  as  of  February  5,  2016,  between
Holdings, Flamel Technologies SA (the predecessor of the Company) and Deerfield and certain of its affiliates, which payment obligations consisted of the
following (collectively, the “Assumed Obligations”): (i) a quarterly payment

-85-

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
of $263  beginning  in  July  2018  and  ending  in  October  2020,  amounting  to  an  aggregate  payment  obligation  of  $2,625;  (ii)  a  payment  in  January  2021
of $15,263;  and  (iii)  a  quarterly  royalty  payment  of  15%  on  net  sales  of  the  FSC  products  through  February  5,  2026  (“FSC  Product  Royalties”),  in  an
aggregate amount of up to approximately $10,300.  Cerecor also assumed certain contracts and other obligations related to the acquired assets, and in that
connection  Holdings  agreed  to  pay  Cerecor  certain  make-whole  payments  associated  with  obligations  Cerecor  is  assuming  related  to  a  certain  supply
contract related to Karbinal™ ER.

In conjunction with the divestiture, the Company also entered into the following arrangements:

License and Development Agreement

Also, in connection with the closing under the Purchase Agreement, Flamel Ireland Limited, an Irish private limited company operating under the
trade  name  of  Avadel  Ireland  (“Avadel  Ireland”)  and  a  wholly-owned  subsidiary  of  the  Company,  and  Cerecor  entered  into  a  license  and
development agreement (the “License and Development Agreement”) pursuant to which, among other things:

•

•

•

•

Avadel Ireland will provide Cerecor with four product formulations utilizing Avadel Ireland’s LiquiTime™ technology, and will complete
pilot bioequivalence studies for such product formulations within 18 months;

Cerecor will reimburse Avadel Ireland for development costs of the four LiquiTime™ products in excess of $1,000 in the aggregate;

Upon transfer of the four product formulations, Cerecor will assume all remaining development costs and responsibilities for the product
development, clinical studies, NDA applications and associated filing fees; and

Upon  regulatory  approval  and  commercial  launch  of  any  LiquiTime™  products,  Cerecor  will  pay  Avadel  Ireland  quarterly  royalties
based on a percentage of net sales of any such products in the mid-single digit range.

Effective October 25, 2019, Cerecor and Avadel Ireland agreed to terminate the License and Development Agreement.

Deerfield Guarantee

In connection with the closing under the Purchase Agreement, the Company and Holdings provided their guarantee (the “Deerfield Guarantee”) in
favor of Deerfield. Under the Deerfield Guarantee, the Company and Holdings guaranteed to Deerfield the payment by Cerecor of the Assumed
Obligations  under  the  Membership  Interest  Purchase  Agreement  between  the  Company  and  Deerfield  dated  February  5,  2016.  The  Assumed
Obligations  include  (i)  a  quarterly  payment  of  $263  beginning  in  July  2018  and  ending  in  October  2020,  amounting  to  an  aggregate  payment
obligation of $2,625; (ii) a payment in January 2021 of $15,263; and (iii) a quarterly royalty payment of 15% on net sales of the FSC products
through February 6, 2026 (“FSC Product Royalties”), in an aggregate amount of up to approximately $10,300. In addition, under the Deerfield
Guarantee, the Company and Holdings guaranteed that Deerfield would receive certain minimum annual FSC Product Royalties through February
6, 2026 (the “Minimum Royalties”). Given the Company’s explicit guarantee to Deerfield, the Company recorded the guarantee in accordance
with ASC 460. A valuation was performed, which was based largely on an analysis of the potential timing of each possible cash outflow described
above and the likelihood of Cerecor’s default on such payments assuming an S&P credit rating of CCC+. The result of this valuation identified a
guarantee liability of $6,643. This liability is being amortized proportionately based on undiscounted cash outflows through the remainder of the
contract with Deerfield.

On October 10, 2019, Cerecor entered into a purchase and sale agreement with Aytu BioScience, Inc (“Buyer”) pursuant to which the Buyer will
purchase  certain  assets  from  Cerecor  and  assume  certain  of  Cerecor’s  liabilities,  including  all  of  Cerecor’s  liabilities  assumed  as  part  of  the
Purchase Agreement noted above. As part of this transaction, on November 1, 2019, Armistice has agreed to deposit $15,000 in an escrow account
governed  by  an  escrow  agreement  between  Armistice  and  Deerfield  having  the  purpose  of  securing  the $15,000 balloon  payment  due  January
2021  as  part  of  the  Membership  Interest  Purchase  Agreement.  As  part  of  the  Cerecor  transaction  with  the  buyer,  Deerfield  contractually
acknowledges and agrees that it will seek payment from the escrow funds before requesting payment from the Company pursuant to the Deerfield
Guarantee discussed above. Due to the change in circumstances, a new valuation was performed based on an analysis of the possible timing of the
updated possible cash flow which excludes the $15,000 that Armistice has deposited in an escrow account. The updated valuation identified an
updated  guarantee  liability  of  $1,827  at  December  31,  2019,  which  will  be  amortized  proportionately  based  on  undiscounted  cash  outflows
through the remainder of the contract with Deerfield.

Armistice Guarantee

In  connection  with  the  closing  under  the  Purchase  Agreement,  Armistice  Capital  Master  Fund,  Ltd.,  the  majority  shareholder  of  Cerecor,
guaranteed to Holdings the payment by Cerecor of the Assumed Obligations, including the Minimum Royalties. A valuation of the guarantee asset
was  performed  in  accordance  with  ASC  460  “Guarantees”  and  a  guarantee  asset  of  $6,620  was  recorded.  This  asset  is  being  amortized
proportionately based on undiscounted cash outflows through the remainder of the contract with Deerfield noted above.

As discussed above, based on the purchase and asset sale between Cerecor and the Buyer, an updated valuation was performed and identified an
updated guarantee asset of $1,821 at December 31, 2019.

The fair values of the Avadel guarantee to Deerfield and the guarantee received by Avadel from Armistice largely offset and when combined are
not material.

Based  on  management’s  review  of  ASU  2014-08,  “Reporting  Discontinued  Operations  and  Disclosures  of  Disposals  of  Components  of  an  Entity”, the
disposition  of  our  pediatric  assets  and  related  liabilities  did  not  qualify  for  discontinued  operations  reporting.  Our  results  of  operations  for  the  period
January 1, 2018 through February 16, 2018 and for the years ended December 31, 2018 and 2017 include the results of FSC, prior to its February 16, 2018
disposition date.

The net impact of this transaction was not material to the consolidated statements of (loss) income.

NOTE 18: Restructuring Costs 

2019 French Restructuring

During the second quarter of 2019, the Company initiated a plan to substantially reduce all of its workforce at its Vénissieux, France site (“2019 French
Restructuring”). This reduction is an effort to align the Company’s cost structure with our ongoing and future planned projects. The reduction in workforce
is  substantially  complete  at  December  31,  2019.  Restructuring  charges  associated  with  this  plan  of  $4,855  were  recognized  during  the  year
ended December 31, 2019. Included in the 2019 French Restructuring charges of $4,855 were charges for employee severance, benefits and other costs
of  $4,339,  charges  related  to  fixed  asset  impairment  of  $629,  charges  related  to  the  early  termination  penalty  related  to  the  office  and  copier  lease
terminations of $887 (see Note 10: Leases), partially offset by a benefit of $1,000 related to the reversal of the French retirement indemnity obligation. The
following table sets forth activities for the Company’s cost reduction plan obligations for the year ended December 31, 2019:

2019 Corporate Restructuring

During  the  first  quarter  of  2019,  the  Company  announced  a  plan  to  reduce  its  Corporate  workforce  by  more  than  50%  (the  “2019  Corporate
Restructuring”). The reduction in workforce is primarily a result of the exit of Noctiva during the first quarter of 2019 (see Note 3: Subsidiary Bankruptcy
and Deconsolidation), as well as an effort to better align the Company’s remaining cost structure at our U.S. and Ireland locations with our ongoing and
future planned projects. The reduction in workforce is substantially complete at December 31, 2019. The restructuring charges associated with this plan
of $1,755 were recognized during the year ended December 31, 2019, respectively. Included in the 2019 Corporate Restructuring charges of $1,755 for the
year ended December 31, 2019, were charges for employee severance, benefit and other costs of $3,406, charges related to the early termination penalty
related to the office lease termination of $288, the write-off of $125 of property, plant and equipment, net,

2017 French Restructuring

During the first quarter of 2017, the Company announced a plan to reduce its workforce at our Venissieux, France site by approximately 50% (the “2017
French Restructuring”).  This reduction was an effort to align the Company’s cost structure with our ongoing and future planned projects. In July 2017, the
Company  completed  negotiations  with  the  works  council  for  our  French  operations  and  received  approval  from  the  French  Labor  Commission
(DIRECCTE) to implement the plan. The reduction was substantially complete at December 31, 2019. The 2017 French Restructuring benefit for the year
ended December 31, 2019 was $169 and the 2017 French Restructuring expense for the year ended December 31, 2018 was $1,164.

NOTE 19: Equity Instruments and Share-Based Compensation 

Capital Shares

We have 500,000 shares of authorized ordinary shares with a nominal value of $0.01 per ordinary share. As of December 31, 2019, we had 42,927 and
37,520 ordinary shares issued and outstanding, respectively. The Board of Directors is authorized to issue preferred shares in series, and with respect to
each  series,  to  fix  its  designation,  relative  rights  (including  voting,  dividend,  conversion,  sinking  fund,  and  redemption  rights),  preferences  (including
dividends and liquidation) and limitations. We have 50,000 shares of authorized preferred shares, $0.01 nominal value, none of which is currently issued
and outstanding.

Share Repurchases

In March 2017, the Board of Directors approved an authorization to repurchase up to $25,000 of Avadel ordinary shares represented by ADSs. Under this
authorization,  which  has  an  indefinite  duration,  share  repurchases  may  be  made  in  the  open  market,  in  block  transactions  on  or  off  the  exchange,  in
privately negotiated transactions, or through other means as determined by the Board of Directors and in accordance with the regulations of the Securities
and  Exchange  Commission.  The  timing  and  amount  of  repurchases,  if  any,  will  depend  on  a  variety  of  factors,  including  the  price  of  our  shares,  cash
resources,  alternative  investment  opportunities,  corporate  and  regulatory  requirements  and  market  conditions.  This  share  repurchase  program  may  be
modified, suspended or discontinued at any time without prior notice. We may also from time to time establish a trading plan under Rule 10b5-1 of the
Securities and Exchange Act of 1934 to facilitate purchases of our shares under this program. Additionally, on

February  12,  2018,  the  Board  of  Directors  approved  an  authorization  to  repurchase  up  to  $18,000  of  Avadel  ordinary  shares  represented  by  American
Depository Shares in connection with our Convertible Notes Offering completed on February 16, 2018. See Note 11: Long-Term Debt. In March 2018, the
Board of Directors approved an authorization to repurchase up to $7,000 of Avadel ordinary shares represented by American Depository Shares, bring the
total authorization to $50,000.   There were no share repurchases during the year ended December 31, 2019. As of December 31, 2019, the Company had
repurchased 5,407 ordinary shares for $49,998.

Share-Based Compensation

Compensation expense included in the Company’s consolidated statements of (loss) income for all share-based compensation arrangements was as follows
for the periods ended December 31, 2019, 2018 and 2017, respectively:

As  of  December  31,  2019,  the  Company  expects  $2,695  of  unrecognized  expense  related  to  granted,  but  non-vested  share-based  compensation
arrangements to be incurred in future periods. This expense is expected to be recognized over a weighted average period of 2.4 years. 

The excess tax benefit related to share-based compensation recorded by the Company was not material for the years ended December 31, 2019, 2018 and
2017.

Upon exercise of stock options or warrants, or upon the issuance of restricted share awards, the Company issues new shares. 

At  December  31,  2019,  there  were  565,716  shares  authorized  for  stock  option  grants,  warrant  grants  and  restricted  share  award  grants  in  subsequent
periods. 

Determining the Fair Value of Stock Options

The Company measures the total fair value of stock options on the grant date using the Black-Scholes option-pricing model and recognizes each grant’s fair
value as compensation expense over the period that the option vests. Options are granted to employees of the Company and become exercisable ratably
over four years following the grant date and expire ten years after the grant date. Prior to 2017, warrants were typically issued to the Company’s Board of
Directors as compensation for services rendered and generally become exercisable within one year following the grant date, and expire four years after the
grant date. Beginning in 2017, the Company issues stock options to our Board of Directors as compensation for services rendered and generally become
exercisable within one year following the grant date, and expire four years after the grant date.

The weighted-average assumptions under the Black-Scholes option-pricing model for stock option grants as of December 31, 2019, 2018 and 2017, are as
follows:

Expected term:  The  expected  term  of  the  options  represents  the  period  of  time  between  the  grant  date  and  the  time  the  options  are  either  exercised  or
forfeited, including an estimate of future forfeitures for outstanding options. Given the limited historical data and the grant of stock options to a limited
population, the simplified method has been used to calculate the expected life. 

Expected  volatility:  The  expected  volatility  is  calculated  based  on  an  average  of  the  historical  volatility  of  the  Company’s  stock  price  for  a  period
approximating the expected term.

Risk-free interest rate: The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant and a maturity that approximates the
expected term. 

Expected dividend yield: We have not distributed any dividends since our inception, and has no plan to distribute dividends in the foreseeable future.

Each of the above warrants is convertible into one ordinary share. There was no  aggregate  intrinsic  value  of  warrants  exercised  during  the  years  ended
December 31, 2019, 2018 and 2017. 

There were no warrants granted during the years ended December 31, 2019, 2018 and 2017.

At January 1, 2018, an additional 3,300 warrants were outstanding and exercisable relative to consideration paid for the Company’s acquisition of Éclat
Pharmaceuticals on March 13, 2012. These warrants are not considered share-based compensation and are therefore excluded from the above tables, and
instead are addressed within Note 12: Long-Term Related Party Payable. On February 23, 2018, the related party exercised in full the warrant to purchase
2,200 ordinary shares. On March 12, 2018 the remaining warrants to purchase 1,100 ordinary shares expired.

Restricted Share Awards 

Restricted  share  awards  represent  Company  shares  issued  free  of  charge  to  employees  of  the  Company  as  compensation  for  services  rendered.  The
Company measures the total fair value of restricted share awards on the grant date using the Company’s stock price at the time of the grant. Restricted share
awards granted during and after 2017 vest over a three-year period; two-thirds (2/3)

the  Company  issues  restricted  share  awards  to  our  Board  of  Directors  vesting  over  a  three-year  period;  one-third  (1/3)  vesting  on  each  of  the  three
anniversaries of the grant date. Compensation expense for such awards granted during and after 2017 is recognized over the applicable vesting period.

Employee Share Purchase Plan

In 2017, the Board of Directors approved of the Avadel Pharmaceuticals plc 2017 Avadel Employee Share Purchase Plan (“ESPP”). The total number of
Company ordinary shares, nominal value $0.01 per share, or ADSs representing such ordinary shares (collectively, “Shares”) which may be issued under
the  ESPP  is  1,000.  The  purchase  price  at  which  a  Share  will  be  issued  or  sold  for  a  given  offering  period  will  be  established  by  the  Compensation
Committee of the Board (“Committee”) (and may differ among participants, as determined by the Committee in its sole discretion) but will in no event be
less than 85% of the lesser of: (a) the fair market value of a Share on the offering date; or (b) the fair market value of a Share on the purchase date. During
the years ended December 31, 2019 and 2018, the Company issued 54 and 25 ordinary shares to employees, respectively. Expense related to the ESPP for
the years ended December 31, 2019 and 2018 was immaterial.

NOTE 20: Net (Loss) Income Per Share 

Basic net (loss) income per share is calculated by dividing net (loss) income by the weighted average number of shares outstanding during each period.
Diluted  net  (loss)  income  per  share  is  calculated  by  dividing  net  (loss)  income  by  the  diluted  number  of  shares  outstanding  during  each  period.  Except
where the result would be anti-dilutive to net (loss) income, diluted net (loss) income per share would be calculated assuming the impact of the conversion
of  the  2023  Notes,  the  exercise  of  outstanding  equity  compensation  awards,  ordinary  shares  expected  to  be  issued  under  our  ESPP  and  the  exercise  of
contingent consideration warrants, all of which have been exercised or have expired during the first quarter of 2018.

We  have  a  choice  to  settle  the  conversion  obligation  under  the  2023  Notes  in  cash,  shares  or  any  combination  of  the  two.  We  utilize  the  if-converted
method to reflect the impact of the conversion of the 2023 Notes, unless the result is anti-dilutive. This method assumes the conversion of the 2023 Notes
into shares of our ordinary shares and reflects the elimination of the interest expense related to the 2023 Notes.

The dilutive effect of the warrants, stock options, RSU’s and ordinary shares expected to be issued under our ESPP has been calculated using the treasury
stock method.

We  have  determined  that  we  operate  in  one  segment,  the  development  and  commercialization  of  pharmaceutical  products,  including  controlled-release
therapeutic products based on our proprietary polymer based technology. The Company’s Chief Operating Decision Maker is the CEO. The CEO reviews
profit and loss information on a consolidated basis to assess performance and make overall operating decisions as well as resource allocations. All products
are included in one segment because the Company’s products have similar economic and other characteristics, including the nature of the products and

NOTE 23: Related Party Transactions 

In March 2012, the Company acquired all of the membership interests of Éclat from Breaking Stick Holdings, L.L.C. (“Breaking Stick”, formerly Éclat
Holdings),  an  affiliate  of  Deerfield  Capital  L.P  (“Deerfield”),  a  significant  shareholder  of  the  Company.  During  the  three  months  ended  December  31,
2019, Deerfield sold all of their shares. At December 31, 2019, the remaining consideration obligation for this transaction consisted of commitments to
make  earnout  payments  to  Breaking  Stick  of  20%  of  any  gross  profit  generated  by  certain  Éclat  products  (the  “Products”).  Breaking  Stick  is  majority
owned  by  Deerfield,  with  a  minority  interest  owned  by  certain  current  and  former  employees.  The  Company  entered  into  a  Security  Agreement  dated
March  13,  2012  with  Breaking  Stick,  whereby  Breaking  Stick  was  granted  a  security  interest  in  various  tangible  and  intangible  assets  related  to  the
Products to secure the obligations of Éclat and Avadel US Holdings, Inc., including the full and prompt payment of royalties to Breaking Stick under the
Royalty Agreement.

As part of a February 2013 debt financing transaction conducted with Deerfield Management, Éclat entered into a Royalty Agreement with Horizon Santé
FLML,  Sarl  and  Deerfield  Private  Design  Fund  II,  L.P.,  both  affiliates  of  the  Deerfield  Entities  (together,  “Deerfield  PDF/Horizon”).  The  Royalty
Agreement provides for the Company to pay Deerfield PDF/Horizon 1.75% of the net sales of the Products sold by the Company and any of our affiliates
until December 31, 2024, with royalty payments paid in arrears for each calendar quarter during the term of the Royalty Agreement. The Company has also
entered into a Security Agreement dated February 4, 2013 with Deerfield PDF/Horizon, whereby Deerfield PDF/Horizon was granted a security interest in
the various tangible and intangible assets related to the Products to secure the obligations of Éclat and Avadel US Holdings, Inc., including the full and
prompt payment of royalties to Deerfield PDF/Horizon under the Royalty Agreement.

As part of a December 2013 debt financing transaction conducted with Broadfin Healthcare Master Fund (“Broadfin”), the Company also entered into a
Royalty Agreement with Broadfin, a significant shareholder of the Company, dated as of December 3, 2013 (the “Broadfin Royalty Agreement”). During
the three months ended December 31, 2019, Broadfin sold a majority of their shares and was not a significant shareholder at December 31, 2019. Pursuant
to the Broadfin Royalty Agreement, the Company is required to pay a royalty of 0.834% on the net sales of certain products sold by the Company and any
of our affiliates until December 31, 2024 with royalty payments paid in arrears for each calendar quarter during the term of the Royalty Agreement. We
also entered into a Security Agreement dated December 3, 2013 with Broadfin, whereby Broadfin was granted a security interest in the various tangible and
intangible assets related to the Products to secure the obligations of Éclat and Avadel US Holdings, Inc., including the full and prompt payment of royalties
to Broadfin under the Royalty Agreement.

The Company entered into an agreement dated February 5, 2016 to acquire FSC Holdings, LLC (“FSC”), a specialty pharmaceutical company dedicated to
providing innovative solutions to unmet medical needs for pediatric patients, from Deerfield CSF, LLC, a Deerfield Management company (“Deerfield”), a
related party. Under the terms of the acquisition, which was completed on February 8, 2016, the Company was to pay $1,050 annually for five years with a
final payment in January 2021 of $15,000 for a total of $20,250 to Deerfield for all of the equity interests in FSC. The Company will also pay Deerfield a
15% royalty per annum on net sales of the current FSC products, up to $12,500 for a period not exceeding ten years.  These obligations were assumed by
Cerecor in connection with the divestiture of the Company’s pediatric products on February 16, 2018. In connection with the divestiture, the Company
provided  its  guarantee  in  favor  of  Deerfield  and  in  return,  Armistice  Capital  Master  Fund,  Inc.,  the  majority  shareholder  of  Cerecor,  guaranteed  to  the
Company the payment by Cerecor of the Assumed Obligations mentioned in Note 17: Divestiture of the Pediatric Assets. On October 10, 2019, Cerecor
entered into a purchase and sale agreement with Aytu BioScience, Inc (“Buyer”) pursuant to which the Buyer will purchase certain assets from Cerecor and
assume certain of Cerecor’s liabilities, including all of Cerecor’s liabilities assumed as part of the Purchase Agreement discussed in Note 17. As part of this
transaction, on November 1, 2019, Armistice has agreed to deposit $15,000 in an escrow account governed by an escrow agreement between Armistice and
Deerfield having the purpose of securing the $15,000 balloon payment due January 2021 as part of the Membership Interest Purchase Agreement. As part
of the Cerecor transaction with the buyer, Deerfield contractually acknowledges

-94-

 
 
 
 
 
 
 
 
 
 
 
 
 
and agrees that it will seek payment from the escrow funds before requesting payment from the Company pursuant to the Deerfield Guarantee discussed
above. Due to the change in circumstances, another valuation was performed based on an analysis of the possible timing of the updated possible cash flow
which excludes the $15,000 that Armistice has deposited in an escrow account. See Note 17 for further discussion around the divestiture.

NOTE 24: Subsequent Events 

Exela Litigation 

On  January  7,  2020,  Exela  filed  a  complaint  against  the  Company  and  its  subsidiary,  Avadel  Legacy  in  the  United  States  District  for  the  District  of
Delaware. The complaint alleges infringement of a certain Exela patent by Avadel’s NOURESS™ product, which has not yet been commercially launched
in the U.S. Exela is most notably seeking i) a declaratory judgment that the NOURESS™ product infringes its patent, ii) an injunction (both preliminary
and permanent) precluding the launch of NOURESS™, and iii) monetary damages (including enhanced damages, prejudgment interest and attorneys’ fees)
in the event NOURESS™ is commercially launched and found to infringe Exela’s patent.  The Company and Avadel Legacy have not yet been served with
the complaint.

Shelf Registration Statement on Form S-3

In February 2020, we filed with the SEC a new shelf registration statement on Form S-3 (the 2020 Shelf Registration Statement) (File No. 333-236258)
that allows issuance and sale by us, from time to time, of:

(a) up to $250,000 in aggregate of ordinary shares, nominal value US$0.01 per share (the “Ordinary Shares”), each of which may be represented by
ADSs, preferred shares, nominal value US$0.01 per share (the “Preferred Shares”), debt securities (the “Debt Securities”), warrants to purchase
Ordinary Shares, ADSs, Preferred Shares and/or Debt Securities (the “Warrants”), and/or units consisting of Ordinary Shares, ADSs, Preferred
Shares, one or more Debt Securities or Warrants in one or more series, in any combination, pursuant to the terms of the 2020 Shelf Registration
Statement, the base prospectus contained in the 2020 Shelf Registration Statement (the “Base Prospectus”), and any amendments or supplements
thereto (together, the “Securities”); including

(b) up to $50,000 of ADSs that may be issued and sold from time to time pursuant to the terms of an Open Market Sale AgreementSM (“the Sales
Agreement”),  entered  into  with  Jefferies  LLC  on  February  4,  2020  (the  “Sales  Agreement”),  the  2020  Shelf  Registration  Statement,  the  Base
Prospectus and the terms of the sales agreement prospectus contained in the 2020 Shelf Registration Statement.

Securities Purchase Agreement (dollars and shares in thousands)

On  February  21,  2020,  we  announced  that  we  have  entered  into  a  definitive  agreement  for  the  sale  of  our  ADSs  and  Series  A  Non-Voting  Convertible
Preferred Shares (“Series A Preferred”) in a private placement to a group of institutional accredited investors. The private placement has resulted in gross
proceeds of approximately $65,000 before deducting placement agent and other offering expenses, and resulting in net proceeds of approximately $61,000.

Pursuant to the terms of the private placement, we issued 8,680 ADSs and 488 shares of Series A Preferred at a price of $7.09 per share, priced at-the-
market under Nasdaq rules. Each share of non-voting Series A Preferred is convertible into one ADS, provided that conversion will be prohibited if, as a
result,  the  holder  and  its  affiliates  would  own  more  than  9.99%  of  the  total  number  of  Avadel  ADSs  outstanding.  The  closing  of  the  private  placement
occurred on February 25, 2020. Proceeds from the private placement will be used to fund continued clinical and program development of FT218, including
an open-label extension study for REST-ON, a switch study to evaluate patients switching from twice-nightly sodium oxybate to once-nightly FT218, as
well as for general corporate purposes. If this transaction would have happened prior to December 31, 2019, ordinary shares issued and outstanding would
have been 51,927 and 46,200, respectively.

related consolidated statements of (loss) income, comprehensive (loss) income, shareholders’ (deficit) equity, and cash flows, for each of the three years in
the period ended December 31, 2019, and the related notes and financial statement schedule listed in the Index at Item 15 (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 and 2018, 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 accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's
internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013) issued
by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 16, 2020, expressed an unqualified opinion on the
Company's internal control over financial reporting.

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 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. 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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of Avadel Pharmaceuticals plc

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Avadel Pharmaceuticals plc (the “Company”) as of December 31, 2019, based on criteria
established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission
(COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019,
based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated
financial statements as of and for the year ended December 31, 2019, of the Company and our report dated March 16, 2020, expressed an unqualified
opinion on those financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of
internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our
responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm
registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating
effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We
believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting
and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control
over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial
statements.

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

Item 9A.    Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

As required by Rule 15d -15(b) of the Exchange Act, we have evaluated, under the supervision and with the participation of our management, including
our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as
defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Annual Report. Our disclosure controls and
procedures are designed to provide reasonable assurance that the information required to be disclosed by us in reports that we file under the Exchange Act
is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow
timely  decisions  regarding  required  disclosure  and  is  recorded,  processed,  summarized  and  reported  within  the  time  periods  specified  in  the  rules  and
forms  of  the  U.S.  Securities  and  Exchange  Commission  (the  “SEC”).  Based  on  that  evaluation,  our  principal  executive  officer  and  principal  financial
officer concluded that as of the end of the period covered by this report our disclosure controls and procedures were effective.

Management’s Report on Internal Control over Financial Reporting

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-
15(f)  and  15d-15(f)  under  the  Securities  Exchange  Act  of  1934,  as  amended.  The  Company’s  internal  control  over  financial  reporting  is  designed  to
provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with U.S. generally
accepted accounting principles.

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

The Company’s management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2019. In making
this  assessment,  the  Company’s  management  used  the  criteria  set  forth  in  Internal  Control-Integrated  Framework  (2013)  issued  by  the  Committee  of
Sponsoring Organizations of the Treadway Commission. Based on this assessment, management concluded that, as of December 31, 2019, the Company’s
internal control over financial reporting is effective based on those criteria.

Changes in Internal Control Over Financial Reporting

During the year ended December 31, 2019 as part of our restructuring initiatives described in this Annual Report under Item 8 “Financial Statements and
Supplementary  Data  -  Note  18  (Restructuring  Costs)”  and  Item  7  “Management  Discussion  and  Analysis  of  Results  of  Operations  and  Financial
Condition - Results of Operation,” we moved all of our Irish and a portion of our French accounting operations to St. Louis, Missouri. Further, as part of
these restructuring initiatives, the Company completed the outsourcing of a majority of its Information Technology resources to a third party. These moves
were made in order to consolidate our accounting systems, gain efficiencies of scale, reduce costs and make internal control over financial reporting more
consistent across our various entities. These moves were not made in response to any identified deficiency or weakness in the Company’s internal control
over financial reporting. Other than these changes, there has been no change in our internal control over financial reporting during the quarter or year
ended December 31, 2019 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Description of the Registrant’s Securities Registered Pursuant to
Section 12 of the Securities Exchange Act of 1934, as amended

The following description of the registered securities of Avadel Pharmaceuticals plc (“Avadel,” “we” or “our”) summarizes the material terms and
provisions of our ordinary shares, which may be represented by American Depositary Shares, or ADSs, and preferred shares. The following description of
our share capital does not purport to be complete and is subject to, and qualified in its entirety by, our memorandum and articles of association (the
“Avadel Constitution”), which is incorporated by reference as Exhibit 3.1 to this Form 10-K , and by applicable law.

The following description includes comparisons of certain provisions of the Avadel Constitution and Irish law applicable to us and the Delaware General
Corporation Law, or the DGCL, the law under which many publicly listed companies in the United States are incorporated. Because such statements are
summaries, they do not address all aspects of Irish law that may be relevant to us and our shareholders or all aspects of Delaware law which may differ
from Irish law, and they are not intended to be a complete discussion of the respective rights.

General

Our authorized share capital is $5,500,000 divided into 500,000,000 ordinary shares with a nominal value of $0.01 each and 50,000,000 preferred shares
with a nominal value of $0.01 each, plus €25,000 divided into 25,000 deferred ordinary shares with a nominal value of €1.00 each.

Ordinary Shares

The holders of ordinary shares are entitled to one vote for each share held of record on all matters submitted to a vote of the shareholders.

Our ordinary shares are not for trading and only registered in connection with the listing of American Depositary Shares (“ADSs”) on the Nasdaq Global
Select Market under the trading symbol “AVDL.”

The transfer agent and registrar for our ordinary shares is Computershare Ireland.

Preferred Shares

The Avadel Constitution empowers our Board of Directors, without action by our shareholders, to issue up to 50,000,000 preferred shares from time to time
in one or more classes or series. Our Board of Directors is authorized, without obtaining any vote or consent of the holders of any class or series of shares,
unless expressly provided by the terms of that class or series of shares, to provide from time to time for the issuance of other classes or series of shares and
to establish the characteristics of each class or series, including the number of shares, designations, relative voting rights, dividend rights, liquidation and
other rights, redemption, repurchase or exchange rights and any other preferences and relative, participating, optional or other rights and limitations not
inconsistent with applicable law.

Warrants

We may issue warrants for the purchase of our ordinary shares, preferred shares or debt securities or any combination thereof. Warrants may be issued
independently or together with our ordinary shares, preferred shares or debt securities and may be attached to or separate from any offered securities. To the
extent warrants that we issue are to be publicly-traded, each series of such warrants will be issued under a separate warrant agreement to be entered into
between us and a bank or trust company, as warrant agent. The warrant agent will act solely as our agent in connection with such warrants. The warrant
agent will not have any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. This summary of certain
provisions of the warrants is not complete. For the terms of a particular series of warrants, you should refer to the prospectus supplement for that series of
warrants and the warrant agreement for that particular series.

Registration Rights

On February 20, 2020, we entered into a Securities Purchase Agreement with purchasers named therein (the “Investors”) for the sale of an aggregate of
8,680,225 ordinary shares in the form of ADSs and 487,614 Series A Non-Voting Convertible Preferred Shares. In connection with the Purchase
Agreement, we entered into a Registration Rights Agreement with the Investors on February 25, 2020 (the “Closing Date”). Pursuant to the Registration
Rights Agreement, we agreed to prepare and

file a registration statement with the Securities and Exchange Commission (the “SEC”) within the later of 30 calendar days following the Closing Date or
the fifth trading day following the filing of the our 2020 definitive Proxy Statement with the SEC.

Anti-Takeover Provisions of Irish Law

Business Combinations with Interested Shareholders

The Avadel Constitution includes a provision similar to Section 203 of the Delaware General Corporation Law, which generally prohibits us from engaging
in a business combination with an interested shareholder for a period of three years following the date the person became an interested shareholder, unless,
in general:

·

·

·

our Board of Directors approved the transaction which resulted in the shareholder becoming an interested shareholder;

upon consummation of the transaction which resulted in the shareholder becoming an interested shareholder, the shareholder owned at least
85% of the voting shares outstanding at the time of commencement of such transaction, excluding for purposes of determining the number
of voting shares outstanding (but not the outstanding voting shares owned by the interested shareholder), voting shares owned by persons
who are directors and also officers and by certain employee share plans; or

the business combination is approved by our Board of Directors and authorized at an annual or extraordinary general meeting of
shareholders by the affirmative vote of the holders of at least 75% of the outstanding voting shares that are not owned by the interested
shareholder.

A “business combination” is generally defined as a merger, asset or stock sale or other transaction resulting in a financial benefit to the interested
shareholder. An “interested shareholder” is generally defined as a person who, together with affiliates and associates, owns or, within three years prior to
the date in question, owned 15% or more of our outstanding voting shares.

Irish Takeover Rules and Substantial Acquisition Rules

A transaction in which a third party seeks to acquire 30% or more of our voting rights and any other acquisitions of our securities will be governed by the
Irish Takeover Panel Act 1997 and the Irish Takeover Rules made thereunder, the Irish Takeover Panel Act, 1997, Takeover Rules, 2013 (the “Irish
Takeover Rules”), and will be regulated by the Irish Takeover Panel. The “General Principles” of the Irish Takeover Rules and certain important aspects of
the Irish Takeover Rules are described below.

General Principles

The Irish Takeover Rules are built on the following General Principles which will apply to any transaction regulated by the Irish Takeover Panel:

in the event of an offer, all holders of securities of the target company must be afforded equivalent treatment and, if a person acquires
control of a company, the other holders of securities must be protected;

the holders of securities in the target company must have sufficient time and information to enable them to reach a properly informed
decision on the offer; where it advises the holders of securities, the Board of Directors of the target company must give its views on the
effects of the implementation of the offer on employment, employment conditions and the locations of the target company’s place of
business;

a target company’s Board of Directors must act in the interests of that company as a whole and must not deny the holders of securities the
opportunity to decide on the merits of the offer;

false markets must not be created in the securities of the target company, the bidder or any other company concerned by the offer in such a
way that the rise or fall of the prices of the securities becomes artificial and the normal functioning of the markets is distorted;

·

·

·

·

 
 
 
 
 
 
 
 
 
 
 
 
 
 
a bidder can only announce an offer after ensuring that he or she can fulfill in full the consideration offered, if such is offered, and after
taking all reasonable measures to secure the implementation of any other type of consideration;

a target company may not be hindered in the conduct of its affairs longer than is reasonable by an offer for its securities; and

a “substantial acquisition” of securities, whether such acquisition is to be effected by one transaction or a series of transactions, shall take
place only at an acceptable speed and shall be subject to adequate and timely disclosure.

·

·

·

Mandatory Bid

Under certain circumstances, a person who acquires shares, or other voting securities, of a company may be required under the Irish Takeover Rules to
make a mandatory cash offer for the remaining outstanding voting securities in that company at a price not less than the highest price paid for the securities
by the acquiror, or any parties acting in concert with the acquiror, during the previous 12 months. This mandatory bid requirement is triggered if an
acquisition of securities would increase the aggregate holding of an acquiror, including the holdings of any parties acting in concert with the acquiror, to
securities representing 30% or more of the voting rights in a company, unless the Irish Takeover Panel otherwise consents. An acquisition of securities by a
person holding, together with its concert parties, securities representing between 30% and 50% of the voting rights in a company would also trigger the
mandatory bid requirement if, after giving effect to the acquisition, the percentage of the voting rights held by that person, together with its concert parties,
would increase by 0.05% within a 12-month period. Any person, excluding any parties acting in concert with the holder, holding securities representing
more than 50% of the voting rights of a company is not subject to these mandatory offer requirements in purchasing additional securities.

Voluntary Bid; Requirements to Make a Cash Offer and Minimum Price Requirement

If a person makes a voluntary offer to acquire our outstanding ordinary shares, the offer price must not be less than the highest price paid for our ordinary
shares by the bidder or its concert parties during the three-month period prior to the commencement of the offer period. The Irish Takeover Panel has the
power to extend the “look back” period to 12 months if the Irish Takeover Panel, taking into account the General Principles, believes it is appropriate to do
so.

If the bidder or any of its concert parties has acquired our ordinary shares (1) during the 12-month period prior to the commencement of the offer period
that represent more than 10% of our total ordinary shares or (2) at any time after the commencement of the offer period, the offer must be in cash or
accompanied by a full cash alternative and the price per ordinary share must not be less than the highest price paid by the bidder or its concert parties
during, in the case of clause (1), the 12-month period prior to the commencement of the offer period or, in the case of (2), the offer period. The Irish
Takeover Panel may apply this Rule to a bidder who, together with its concert parties, has acquired less than 10% of our total ordinary shares in the 12-
month period prior to the commencement of the offer period if the Irish Takeover Panel, taking into account the General Principles, considers it just and
proper to do so.

An offer period will generally commence from the date of the first announcement of the offer or proposed offer.

Substantial Acquisition Rules

The Irish Takeover Rules also contain rules governing substantial acquisitions of shares and other voting securities which restrict the speed at which a
person may increase his or her holding of shares and rights over shares to an aggregate of between 15% and 30% of the voting rights of the company.
Except in certain circumstances, an acquisition or series of acquisitions of shares or rights over shares representing 10% or more of the voting rights of the
company is prohibited, if such acquisition(s), when aggregated with shares or rights already held, would result in the acquirer holding 15% or more but less
than 30% of the voting rights of the company and such acquisitions are made within a period of seven days. These rules also require accelerated disclosure
of acquisitions of shares or rights over shares relating to such holdings.

Frustrating Action

Under the Irish Takeover Rules, our Board of Directors is not permitted to take any action that might frustrate an offer for our shares once our Board of
Directors has received an approach that may lead to an offer or has reason to believe that such an offer is or may be imminent, subject to certain exceptions.
Potentially frustrating actions such as 1) the issue of shares, options,

 
 
 
 
 
 
 
 
 
 
 
 
 
restricted share units or convertible securities, (2) material acquisitions or disposals, (3) entering into contracts other than in the ordinary course of business
or (4) any action, other than seeking alternative offers, which may result in frustration of an offer, are prohibited during the course of an offer or at any
earlier time during which our Board of Directors has reason to believe an offer is or may be imminent. Exceptions to this prohibition are available where:

(a) the action is approved by our shareholders at a general meeting; or

(b) the Irish Takeover Panel has given its consent, where:

(i) it is satisfied the action would not constitute frustrating action;

(ii) our shareholders holding more than 50% of the voting rights state in writing that they approve the proposed action and would vote in
favor of it at a general meeting;

(iii) the action is taken in accordance with a contract entered into prior to the announcement of the offer, or any earlier time at which our
Board of Directors considered the offer to be imminent; or

(iv) the decision to take such action was made before the announcement of the offer and either has been at least partially implemented or
is in the ordinary course of business.

Shareholders’ Rights Plan

Irish law does not expressly authorize or prohibit companies from issuing share purchase rights or adopting a shareholder rights plan as an anti-takeover
measure. However, there is no directly relevant case law on the validity of such plans under Irish law. In addition, such a plan would be subject to the Irish
Takeover Rules and the General Principles underlying the Irish Takeover Rules. The Avadel Constitution allows our Board of Directors to adopt a
shareholder rights plan upon such terms and conditions as our Board of Directors deems expedient and in the best interests of us, subject to applicable law.

Subject to the Irish Takeover Rules, our Board of Directors also has power to issue any of our authorized and unissued shares on such terms and conditions
as it may determine and any such action should be taken in our best interests. It is possible, however, that the terms and conditions of any issue of
preference shares could discourage a takeover or other transaction that holders of some or a majority of the ordinary shares believe to be in their best
interests or in which holders might receive a premium for their shares over the then-market price of the shares.

Disclosure of Interests in Shares

Under the Irish Companies Act, our shareholders must notify us if, as a result of a transaction, the shareholder will become interested in three percent or
more of our voting shares, or if as a result of a transaction a shareholder who was interested in three percent or more of our voting shares ceases to be so
interested. Where a shareholder is interested in three percent or more of our voting shares, the shareholder must notify us of any alteration of his or her
interest that brings his or her total holding through the nearest whole percentage number, whether an increase or a reduction. The relevant percentage figure
is calculated by reference to the aggregate nominal value of the voting shares in which the shareholder is interested as a proportion of the entire nominal
value of our issued share capital (or any such class of share capital in issue). Where the percentage level of the shareholder’s interest does not amount to a
whole percentage, this figure may be rounded down to the next whole number. We must be notified within five business days of the transaction or alteration
of the shareholder’s interests that gave rise to the notification requirement. If a shareholder fails to comply with these notification requirements, the
shareholder's rights in respect of any of our shares it holds will not be enforceable, either directly or indirectly. However, such person may apply to the
court to have the rights attaching to such shares reinstated.

In addition to these disclosure requirements, we, under the Irish Companies Act, may, by notice in writing, require a person whom we know or have
reasonable cause to believe to be, or at any time during the three years immediately preceding the date on which such notice is issued to have been,
interested in shares comprised in our relevant share capital to (i) indicate whether or not it is the case and (ii) where such person holds or has during that
time held an interest in our shares, to provide additional information, including the person's own past or present interests in our shares. If the recipient of
the notice fails to respond within the reasonable time period specified in the notice, we may apply to the Irish court for an order directing that the affected
shares be subject to certain restrictions, as prescribed by the Irish Companies Act, as follows:

 
 
 
 
 
 
 
 
 
 
 
 
any transfer of those shares or, in the case of unissued shares, any transfer of the right to be issued with shares and any issue of shares, shall
be void;

no voting rights shall be exercisable in respect of those shares;

no further shares shall be issued in right of those shares or in pursuance of any offer made to the holder of those shares; and

no payment shall be made of any sums due from us on those shares, whether in respect of capital or otherwise.

·

·

·

·

The court may also order that shares subject to any of these restrictions be sold with the restrictions terminating upon the completion of the sale.

In the event we are in an offer period pursuant to the Irish Takeover Rules, accelerated disclosure provisions apply for persons holding an interest in our
securities of one percent or more.

Differences in Corporate Law

As a public limited company incorporated under the laws of Ireland, the rights of our shareholders are governed by applicable Irish law, including the Irish
Companies Act, and not by the law of any U.S. state. As a result, our directors and shareholders are subject to different responsibilities, rights and
privileges than are applicable to directors and shareholders of U.S. corporations. The applicable provisions of the Irish Companies Act differ from laws
applicable to U.S. corporations and their shareholders. Set forth below is a summary of certain differences between the provisions of the Irish Companies
Act applicable to us and the General Corporation Law of the State of Delaware relating to shareholders' rights and protections. The applicable provisions in
respect of the Company under the Avadel Constitution is also set out where relevant. This summary is not intended to be a complete discussion of the
respective rights and it is qualified in its entirety by reference to Delaware law and Irish law. You are also urged to carefully read the relevant provisions of
the Delaware General Corporation Law and the Irish Companies Act for a more complete understanding of the differences between Delaware and Irish law.

Number of Directors

Ireland

Delaware

Under Delaware law, a corporation must have at
least one director and the number of directors
shall be fixed by or in the manner provided in
the bylaws.

The Irish Companies Act provides for a
minimum of two directors. The Avadel
Constitution provides for a minimum of two
directors and a maximum of 13. Our
shareholders may from time to time increase or
reduce the maximum number, or increase the
minimum number, of directors by ordinary
resolution. Our Board of Directors determines
the number of directors within the range of two
to 13.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Removal of Directors

Under Delaware law, any director or the entire
board of directors may be removed, with or
without cause, by the holders of a majority of
the shares then entitled to vote at an election of
directors, except (i) unless the certificate of
incorporation provides otherwise, in the case of
a corporation whose board of directors is
classified, stockholders may effect such
removal only for cause, or (ii) in the case of a
corporation having cumulative voting, if less
than the entire board of directors is to be
removed, no director may be removed without
cause if the votes cast against his removal
would be sufficient to elect him if then
cumulatively voted at an election of the entire
board of directors, or, if there are classes of
directors, at an election of the class of directors
of which he is a part.

Under the Irish Companies Act, the
shareholders may, by ordinary
resolution, remove a director from office before
the expiration of his or her term, at a meeting
held no less than 28 days’ notice and at which
the director is entitled to be heard. Because of
this provision of
the Irish Companies Act, a director may be so
removed before the expiration of his or her
period of office.
The power of removal is without prejudice to
any claim for damages for breach of contract
(e.g., employment contract) that the director
may have against the Company in respect of his
or her removal.

The Avadel Constitution also provides that the
office of a director will also be vacated if the
director is restricted or disqualified to act as a
director under the Irish Companies Act; resigns
his or her office by notice in writing to us or in
writing offers to resign and the directors resolve
to accept such offer; or is requested to resign in
writing by not less than 75% of the other
directors.

 
 
Vacancies on the Board of Directors

Under Delaware law, vacancies and newly
created directorships may be filled by a
majority of the directors then in office (even
though less than a quorum) or by a sole
remaining director unless (i) otherwise provided
in the certificate of incorporation or bylaws of
the corporation or (ii) the certificate of
incorporation directs that a particular class of
stock is to elect such director, in which case a
majority of the other directors elected by such
class, or a sole remaining director elected by
such class, will fill such vacancy.

Any vacancy on our Board of Directors,
including a vacancy resulting from an increase
in the number of directors or from the death,
resignation, retirement, disqualification or
removal of a director, shall be deemed a casual
vacancy. Subject to the terms of any one or
more classes or series of preferred shares, any
casual vacancy shall only be filled by the
decision of a majority of our Board of Directors
then in office, provided that a quorum is present
and provided that the appointment does not
cause the number of directors to exceed any
number fixed by or in accordance with the
Avadel Constitution as the maximum number of
directors.

Any director of a class of directors elected to
fill a vacancy resulting from an increase in the
number of directors of such class shall hold
office for the remaining term of that class. Any
director elected to fill a vacancy not resulting
from an increase in the number of directors
shall have the same remaining term as that of
his predecessor. A director retiring at a meeting
shall retain office until the close or adjournment
of the meeting.

 
 
 
Annual General Meeting

General Meeting

Under Delaware law, the annual meeting of
stockholders shall be held at such place, on such
date and at such time as may be designated
from time to time by the board of directors or as
provided in the certificate of incorporation or by
the bylaws.

Under Delaware law, special meetings of the
stockholders may be called by the board of
directors or by such person or persons as may
be authorized by the certificate of incorporation
or by the bylaws.

We are required to hold annual general
meetings at intervals of no more than fifteen
months after the previous annual general
meeting, provided that an annual general
meeting is held in each calendar year following
our first annual general meeting, no more than
nine months after our fiscal year-end.

The only matters which must, as a matter of
Irish company law, be transacted at an annual
general meeting are the consideration of the
Irish statutory financial statements, the report of
the directors, the report of the auditors on those
statements and that report and a review by the
members of our affairs. If no resolution is made
in respect of the reappointment of an auditor at
an annual general meeting, the previous auditor
will be deemed to have continued in office.

Our extraordinary general meetings may be
convened by (i) our Board of Directors, (ii) on
requisition of shareholders holding not less than
10% of our paid up share capital carrying
voting rights or (iii) on requisition of our
auditors. Extraordinary general meetings are
generally held for the purposes of approving
shareholder resolutions as may be required from
time to time.
If our directors become aware that our net
assets are half or less of the amount of our
called-up share capital, our directors must
convene an extraordinary general meeting of
our shareholders not later than 28 days from the
date that they learn of this fact. This meeting
must be convened for the purposes of
considering whether any, and if so what,
measures should be taken to address the
situation.

 
   
 
 
 
Notice of General Meetings

Under Delaware law, unless otherwise provided
in the certificate of incorporation or bylaws,
written notice of any meeting of the
stockholders must be given to each stockholder
entitled to vote at the meeting not less than ten
nor more than 60 days before the date of the
meeting and shall specify the place, date, hour
and purpose or purposes of the meeting.

Notice of a general meeting must be given to all
our shareholders and to our auditors. The
Avadel Constitution provides that the maximum
notice period is 60 days. The minimum notice
periods are 21 days’ notice in writing for an
annual general meeting or an extraordinary
general meeting to approve a special resolution
and 14 days’ notice in writing for any other
extraordinary general meeting. General
meetings may be called by shorter notice, but
only with the consent of our auditors and all of
our shareholders entitled to attend and vote
thereat. Because of the 21-day and 14-day
requirements described in this paragraph, the
Avadel Constitution includes provisions
reflecting these requirements of Irish law.

In the case of an extraordinary general meeting
convened by our shareholders, the proposed
purpose of the meeting must be set out in the
requisition notice. Upon receipt of this
requisition notice, our Board of Directors has
21 days to convene a meeting of our
shareholders to vote on the matters set out in the
requisition notice. This meeting must be held
within two months of the receipt of the
requisition notice. If our Board of Directors
does not convene the meeting within such 21-
day period, the requisitioning shareholders, or
any of them representing more than one half of
the total voting rights of all of them, may
themselves convene a meeting, which meeting
must be held within three months of the receipt
of the requisition notice.

 
 
 
Quorum

Proxy

The presence, in person or by proxy, of five or
more persons holding or representing by proxy
at least a majority in nominal value of the class
or, at any adjourned meeting of such holders,
one holder holding or representing by proxy at
least a majority in nominal value of the issued
shares of the class constitutes a quorum for the
conduct of business. No business may take
place at a general meeting if a quorum is not
present in person or by proxy. Our Board of
Directors has no authority to waive quorum
requirements stipulated in the Avadel
Constitution. Abstentions and broker non-votes
will be counted as present for purposes of
determining whether there is a quorum in
respect of the proposals.

The certificate of incorporation or bylaws may
specify the number of shares, the holders of
which shall be present or represented by proxy
at any meeting in order to constitute a quorum,
but in no event shall a quorum consist of less
than one third of the shares entitled to vote at
the meeting. In the absence of such
specification in the certificate of incorporation
or bylaws, a majority of the shares entitled to
vote, present in person or represented by proxy,
shall constitute a quorum at a meeting of
stockholders.

Under Irish law, a shareholder may designate
another person to attend, speak and vote at a
general meeting of the company on their behalf
by proxy, which proxy need not be a
shareholder.
Where interests in shares are held by a nominee
trust company, this company may exercise the
rights of the beneficial holders on their behalf
as their proxy.

Under Delaware law, at any meeting of
stockholders, a stockholder may designate
another person to act for such stockholder by
proxy, but no such proxy shall be voted or acted
upon after three years from its date, unless the
proxy provides for a longer period. A director
of a Delaware corporation may not issue a
proxy representing the director's voting rights as
a director.

Voting rights may be exercised by shareholders
registered in the share register as of the record
date for the meeting or by a duly appointed
proxy of such a registered shareholder, which
proxy need not be a shareholder. Where
interests in shares are held by a nominee trust
company, this company may exercise the rights
of the beneficial holders on their behalf as their
proxy. All proxies must be appointed in
accordance with the Avadel Constitution. The
Avadel Constitution permits the appointment of
proxies by our shareholders to be notified to us
electronically, when permitted by our directors.

 
 
 
 
Issue of New Shares

Under Delaware law, if the company's
certificate of incorporation so provides, the
directors have the power to authorize the
issuance of additional stock. The directors may
authorize capital stock to be issued for
consideration consisting of cash, any tangible or
intangible property or any benefit to the
company or any combination thereof.

Under the Avadel Constitution, we may issue
shares subject to the maximum authorized share
capital contained in the Avadel Constitution.
The authorized share capital may be increased
or reduced by a resolution approved by a simple
majority of the votes cast at a general meeting
of our shareholders, referred to under Irish law
as an “ordinary resolution.” As a matter of Irish
law, the directors of a company may issue new
ordinary or preferred shares without shareholder
approval once authorized to do so by its
constitution or by an ordinary resolution
adopted by our shareholders at a general
meeting. The authorization may be granted for a
maximum period of five years, at which point it
may be renewed by shareholders by an ordinary
resolution. Accordingly, the Avadel
Constitution authorizes our Board of Directors
to issue new ordinary or preferred shares
without shareholder approval for a period of
five years from the date of the adoption of the
Avadel Constitution. The authority to issue
preferred shares provides us with the flexibility
to consider and respond to future business needs
and opportunities as they arise from time to
time, including in connection with capital
raising, financing and acquisition transactions
or opportunities.

Under the Avadel Constitution, our Board of
Directors will be authorized to issue preferred
shares on a non-pre-emptive basis, with
discretion as to the terms attaching to the
preferred shares, including as to voting,
dividend and conversion rights and priority
relative to other classes of shares with respect to
dividends and upon a liquidation. As described
in the preceding paragraph, this authority
extends until five years from the date of the
adoption of the Avadel Constitution, at which
time it will expire unless renewed by our
shareholders.

Notwithstanding this authority, under the Irish
Takeover Rules our Board of Directors would
not be permitted to issue any of our shares,
including preferred shares, during a period
when an offer has been made for us or is
believed to be imminent unless the issue is
(i) approved by our shareholders at a general
meeting; (ii) consented to by the Irish Takeover
Panel on the basis it would not constitute action
frustrating the offer;

 
 
 
 
(iii) consented to by the Irish Takeover Panel
and approved by the holders of more than 50%
of our shares carrying voting rights;
(iv) consented to by the Irish Takeover Panel in
circumstances where a contract for the issue of
the shares had been entered into prior to that
period; or (v) consented to by the Irish
Takeover Panel in circumstances where the
issue of the shares was decided by our directors
prior to that period and either action has been
taken to implement the issuance (whether in
part or in full) prior to such period or the
issuance was otherwise in the ordinary course
of business.

 
 
 
 
Preemptive Rights

Under Delaware law, shareholders have no
preemptive rights to subscribe to additional
issues of stock or to any security convertible
into such stock unless, and except to the extent
that, such rights are expressly provided for in
the certificate of incorporation.

Under Irish law, unless otherwise authorized,
when an Irish public limited company issues
shares for cash to new shareholders, it is
required first to offer those shares on the same
or more favorable terms to existing
shareholders of the company on a pro rata basis,
commonly referred to as the statutory
preemption right. However, we have opted out
of these preemption rights in the Avadel
Constitution as permitted under Irish law.
Because Irish law permits this opt-out to last for
a maximum of five years, the Avadel
Constitution provides that this opt-out will lapse
five years after the adoption of the Avadel
Constitution. Such opt-out may be renewed by a
special resolution of the shareholders. A special
resolution requires not less than 75% of the
votes cast at a general meeting of our
shareholders. If the opt-out is not renewed,
shares issued for cash must be offered to pre-
existing shareholders of Avadel plc pro rata to
their existing shareholding before the shares can
be issued to any new shareholders. The
statutory preemption rights do not apply where
shares are issued for non-cash consideration and
do not apply to the issue of non-equity shares
(that is, shares that have the right to participate
only up to a specified amount in any income or
capital distribution).

 
 
Authority to Allot

Under Delaware law, if the corporation's charter
or certificate of incorporation so provides, the
board of directors has the power to authorize
the issuance of stock. The board may authorize
capital stock to be issued for consideration
consisting of cash, any tangible or intangible
property or any benefit to the corporation or any
combination thereof. It may determine the
amount of such consideration by approving a
formula. In the absence of actual fraud in the
transaction, the judgment of the directors as to
the value of such consideration is conclusive.

Under the Avadel Constitution, we may issue
shares subject to the maximum authorized share
capital contained in the Avadel Constitution.
The authorized share capital may be increased
or reduced by a resolution approved by a simple
majority of the votes cast at a general meeting
of our shareholders, referred to under Irish law
as an “ordinary resolution.” Our authorized
share capital may be divided into shares of such
nominal value as the resolution shall prescribe.
As a matter of Irish law, the directors of a
company may issue new ordinary or preferred
shares without shareholder approval once
authorized to do so by its constitution or by an
ordinary resolution adopted by our shareholders
at a general meeting. The authorization may be
granted for a maximum period of five years, at
which point it may be renewed by shareholders
by an ordinary resolution. Accordingly, the
Avadel Constitution authorizes our Board of
Directors to issue new ordinary or preferred
shares without shareholder approval for a
period of five years from the date of the
adoption of the Avadel Constitution. The
authority to issue preferred shares provides us
with the flexibility to consider and respond to
future business needs and opportunities as they
arise from time to time, including in connection
with capital raising, financing and acquisition
transactions or opportunities.

 
 
Liability of Directors and Officers

Voting Rights

Under Delaware law, a corporation's certificate
of incorporation may include a provision
eliminating or limiting the personal liability of a
director to the corporation and its stockholders
for damages arising from a breach of fiduciary
duty as a director. However, no provision can
limit the liability of a director for:
 any breach of the director's duty of loyalty to
the corporation or its stockholders;
 acts or omissions not in good faith or that
involve intentional misconduct or a knowing
violation of law;
 intentional or negligent payment of unlawful
dividends or stock purchases or redemptions; or
 any transaction from which the director derives
an improper personal benefit.

Delaware law provides that, unless otherwise
provided in the certificate of incorporation, each
stockholder is entitled to one vote for each
share of capital stock held by such stockholder.

To the fullest extent permitted by Irish law, the
Avadel Constitution contains indemnification
for the benefit of our directors, company
secretary and executive officers. However, as to
our directors and company secretary, this
indemnity is limited by the Irish Companies
Act, which prescribes that an advance
commitment to indemnify only permits a
company to pay the costs or discharge the
liability of a director or company secretary
where judgment is given in favor of the director
or company secretary in any civil or criminal
action in respect of such costs or liability, or
where an Irish court grants relief because the
director or company secretary acted honestly
and reasonably and ought fairly to be excused.
Any provision whereby an Irish company seeks
to commit in advance to indemnify its directors
or company secretary over and above the
limitations imposed by the Irish Companies Act
will be void, whether contained in its articles of
association or any contract between the
company and the director or company secretary.
This restriction does not apply to our executive
officers who are not directors, our company
secretary or other persons who would be
considered “officers” within the meaning of the
Irish Companies Act.

We are permitted under the Avadel Constitution
and the Irish Companies Act to take out
directors' and officers’ liability insurance, as
well as other types of insurance, for our
directors, officers, employees and agents. In
order to attract and retain qualified directors and
officers, we expect to purchase and maintain
customary directors' and officers’ liability
insurance and other types of comparable
insurance.

Under the Avadel Constitution, each holder of
our ordinary shares is entitled to one vote for
each ordinary share that he or she holds as of
the record date for the meeting. The holder of
our deferred ordinary shares is not entitled to a
vote. We may not exercise any voting rights in
respect of any shares held as treasury shares.
Any shares held by our subsidiaries will count
as treasury shares for this purpose, and such
subsidiaries cannot therefore exercise any
voting rights in respect of those shares.

 
 
 
 
 
 
 
 
 
 
Shareholder Vote on Certain Transactions

Generally, under Delaware law, unless the
certificate of incorporation provides for the vote
of a larger portion of the stock, completion of a
merger, consolidation, sale, lease or exchange
of all or substantially all of a corporation's
assets or dissolution requires:

 the approval of the board of directors; and
 the approval by the vote of the holders of a
majority of the outstanding stock or, if the
certificate of incorporation provides for more or
less than one vote per share, a majority of the
votes of the outstanding stock of the corporation
entitled to vote on the matter.

Pursuant to Irish law, shareholder approval in
connection with a transaction involving the
Company would be required under the
following circumstances:

in connection with a scheme of arrangement,
both a court order from the Irish High Court and
the approval of a majority in number
representing 75% in value of the shareholders
present and voting in person or by proxy at a
meeting called to approve such a scheme would
be required;

in connection with an acquisition of the
Company by way of a merger with an EU
company under the EU Cross-Border Mergers
Directive 2005/56/EC, (as replaced by Directive
(EU) 2017/1132 of 14 June 2017), approval by
a special resolution of the shareholders would
be required; and

in connection with a merger with an Irish
company under the Irish Companies Act,
approval by a special resolution of shareholders
would be required.

 
 
Standard of Conduct for Directors

The directors of the Company have certain
statutory and fiduciary duties as a matter of
Irish law. All of the directors have equal and
overall responsibility for the management of the
Company (although directors who also serve as
employees may have additional responsibilities
and duties arising under their employment
agreements (if applicable), and it is likely that
more will be expected of them in compliance
with their duties than non-executive directors).
The Irish Companies Act provides specifically
for certain fiduciary duties of the directors of
Irish companies, including duties:

to act in good faith and in the best interests of
the company;

to act honestly and responsibly in relation to the
company’s affairs;

to act in accordance with the company’s
constitution and to exercise powers only for
lawful purposes;

not to misuse the company’s property,
information and/or opportunity;

not to fetter their independent judgment;

to avoid conflicts of interest;

to exercise care, skill and diligence; and

to have regard for the interests of the company’s
shareholders.

Other statutory duties of directors include
ensuring the maintenance of proper books of
account, having annual accounts prepared,
having an annual audit performed, maintaining
certain registers, making certain filings and
disclosing personal interests. Directors of public
limited companies such as Avadel will have a
specific duty to ensure that the company
secretary is a person with the requisite
knowledge and experience to discharge the role.
Directors may rely on information, opinions,
reports or statements, including financial
statements and other financial data, prepared or
presented by

Delaware law does not contain specific
provisions setting forth the standard of conduct
of a director. The scope of the fiduciary duties
of directors is generally determined by the
courts of the State of Delaware. In general,
directors have a duty to act without self-interest,
on a well-informed basis and in a manner they
reasonably believe to be in the best interest of
the stockholders.

Directors of a Delaware corporation owe
fiduciary duties of care and loyalty to the
corporation and to its shareholders. The duty of
care generally requires that a director act in
good faith, with the care that an ordinarily
prudent person would exercise under similar
circumstances. Under this duty, a director must
inform himself of all material information
reasonably available regarding a significant
transaction. The duty of loyalty requires that a
director act in a manner he reasonably believes
to be in the best interests of the corporation. He
must not use his corporate position for personal
gain or advantage. In general, but subject to
certain exceptions, actions of a director are
presumed to have been made on an informed
basis, in good faith and in the honest belief that
the action taken was in the best interests of the
corporation. However, this presumption may be
rebutted by evidence of a breach of one of the
fiduciary duties. Delaware courts have also
imposed a heightened standard of conduct upon
directors of a Delaware corporation who take
any action designed to defeat a threatened
change in control of the corporation.

In addition, under Delaware law, when the
board of directors of a Delaware corporation
approves the sale or break-up of a corporation,
the board of directors may, in certain
circumstances, have a duty to obtain the highest
value reasonably available to the shareholders.

 
 
(1) other directors, officers or employees of the
company whom the director reasonably believes
to be reliable and competent in the matters
prepared or presented, (2) legal counsel, public
accountants or other persons as to matters the
director reasonably believes to be within their
professional or expert competence, or (3) a
committee of the board of which the director
does not serve as to matters within its
designated authority, which committee the
director reasonably believed to merit
confidence.

Shareholder Suits

Under Delaware law, a stockholder may initiate
a derivative action to enforce a right of a
corporation if the corporation fails to enforce
the right itself. The complaint must:

 state that the plaintiff was a stockholder at the
time of the transaction of which the plaintiff
complains or that the plaintiffs shares thereafter
devolved on the plaintiff by operation of law;
and
 allege with particularity the efforts made by the
plaintiff to obtain the action the plaintiff desires
from the directors and the reasons for the
plaintiff's failure to obtain the action; or
 state the reasons for not making the effort.

Additionally, the plaintiff must remain a
stockholder through the duration of the
derivative suit. The action will not be dismissed
or compromised without the approval of the
Delaware Court of Chancery.

In Ireland, the decision to institute proceedings
is generally taken by a company’s board of
directors,
who will usually be empowered to manage the
company’s business. In certain limited
circumstances, a shareholder may be entitled to
bring a derivative action on behalf of the
company.
The central question at issue in deciding
whether a minority shareholder may be
permitted to bring a derivative action is
whether, unless the action is
brought, a wrong committed against the
company would otherwise go un-redressed.
The principal case law in Ireland indicates that
to bring a derivative action a person must first
establish a prima facie case (i) that the company
is entitled to the relief claimed and (ii) that the
action
falls within one of the five exceptions derived
from case law, as follows:
(1) where an ultra vires or illegal act is
perpetrated;
(2) where more than a bare majority is required
to ratify the “wrong” complained of;
(3) where the shareholders’ personal rights are
infringed;
(4) where a fraud has been perpetrated upon a
minority by those in control; or
(5) where the justice of the case requires a
minority to be permitted to institute
proceedings.
Shareholders may also bring proceedings
against the company where the affairs of the
company are being conducted, or the powers of
the directors are being exercised, in a manner
oppressive to the
shareholders or in disregard of their interests.
Oppression connotes conduct that is
burdensome, harsh or wrong.

Conduct must relate to the internal
management of the company. This is an Irish
statutory remedy and the court can grant any
order it sees fit, usually providing for the
purchase or transfer of the shares of any
shareholder.

 
 
American Depositary Shares

The Bank of New York Mellon, as depositary, registers and delivers our ADSs. Each ADS represents one share (or a right to receive one share) deposited
with The Bank of New York Mellon, acting through an office located in the United Kingdom, as custodian for the depositary. Each ADS also represents
any other securities, cash or other property which may be held by the depositary. The depositary’s office at which the ADSs will be administered and its
principal executive office are located at 240 Greenwich Street, New York, New York 10286.

ADSs may be held either (A) directly (i) by having an American Depositary Receipt (an “ADR”), which is a certificate evidencing a specific number of
ADSs, registered in the name of the holder, or (ii) by having uncertificated ADSs registered in the name of the holder, or (B) indirectly by holding a
security entitlement in ADSs through a broker or other financial institution that is a direct or indirect participant in The Depository Trust Company, also
called DTC. This description assumes you are an ADS holder, which is the case if the ADS is directly held. If the ADSs are indirectly held, holders must
rely on the procedures of their broker or other financial institution to assert the rights of ADS holders described in this section. We encourage all holders to
consult with their broker or financial institution to find out what those procedures are.

ADS holders are not treated as one of our shareholders and do not have shareholder rights. Irish law governs shareholder rights. The depositary will be the
holder of the shares underlying your ADSs. As a registered holder of ADSs, you will have ADS holder rights. A deposit agreement among us, the
depositary, ADS holders and all other persons indirectly or beneficially holding ADSs sets out ADS holder rights as well as the rights and obligations of the
depositary. New York law governs the deposit agreement and the ADSs.

The following is a summary of the material provisions of the deposit agreement. This summary the depositary agreement does not purport to be complete
and is not intended to be a complete discussion of the respective rights.

Dividends and Other Distributions

The depositary has agreed to pay or distribute to ADS holders the cash dividends or other distributions it or the custodian receives on shares or other
deposited securities, upon payment or deduction of its fees and expenses. These distributions are to be made in proportion to the number of shares the
ADSs represent. 

Cash. The depositary will (if necessary) convert any cash dividend or other cash distribution we pay on the shares into U.S. dollars, if it can do so on a

reasonable basis and can transfer the U.S. dollars to the United States. If that is not possible or if any government approval is needed and cannot
be obtained, the deposit agreement allows the depositary to distribute the foreign currency only to those ADS holders to whom it is possible to do
so. It will hold the foreign currency it cannot convert for the account of the ADS holders who have not been paid. It will not invest the foreign
currency and it will not be liable for any interest.

Before making a distribution, any withholding taxes, or other governmental charges that must be paid will be deducted.

The depositary will distribute only whole U.S. dollars and cents and will round fractional cents to the nearest whole cent. If the exchange rates
fluctuate during a time when the depositary cannot convert the foreign currency, some value of the distribution may be lost.

Shares. The depositary may distribute additional ADSs representing any shares we distribute as a dividend or fee distribution. The depositary will only

distribute whole ADSs. It will sell shares which would require it to deliver a fraction of an ADS (or ADSs representing those shares) and distribute
the net proceeds in the same way as it does with cash. If the depositary does not distribute additional ADSs, the outstanding ADSs will also
represent the new shares. The depositary may sell a portion of the distributed shares (or ADSs representing those shares) sufficient to pay its fees
and expenses in connection with that distribution.

Rights to purchase additional shares. If we offer holders of our securities any rights to subscribe for additional shares or any other rights, the depositary

may (i) exercise those rights on behalf of ADS holders, (ii) distribute those rights to ADS holders or (iii) sell those rights and distribute the net
proceeds to ADS holders, in each case after deduction or upon payment of its fees and expenses. To the extent the depositary does not do any of
those things, it will allow the rights to lapse and no value will be distributed. The depositary will exercise or distribute rights only if we ask it to
and provide satisfactory assurances to the depositary that it is legal to do so. If the depositary will exercise rights, it will purchase the securities to
which the rights relate and distribute those securities or, in the case of shares, new ADSs

 
 
  
 
  
 
 
 
 
 
representing the new shares, to subscribing ADS holders, but only if ADS holders have paid the exercise price to the depositary. U.S. securities
laws may restrict the ability of the depositary to distribute rights or ADSs or other securities issued on exercise of rights to all or certain ADS
holders, and the securities distributed may be subject to restrictions on transfer.

Other Distributions. The depositary will send to ADS holders anything else we distribute on deposited securities by any means it thinks is legal, fair and

practical. If it cannot make the distribution in that way, the depositary has a choice. It may decide to sell what we distributed and distribute the net
proceeds, in the same way as it does with cash. Or, it may decide to hold what we distributed, in which case ADSs will also represent the newly
distributed property. However, the depositary is not required to distribute any securities (other than ADSs) to ADS holders unless it receives
satisfactory evidence from us that it is legal to make that distribution. The depositary may sell a portion of the distributed securities or property
sufficient to pay its fees and expenses in connection with that distribution. U.S. securities laws may restrict the ability of the depositary to
distribute securities to all or certain ADS holders, and the securities distributed may be subject to restrictions on transfer.

The depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any ADS holders. We have no obligation
to register ADSs, shares, rights or other securities under the Securities Act. We also have no obligation to take any other action to permit the distribution of
ADSs, shares, rights or anything else to ADS holders.

Deposit, Withdrawal and Cancellation

The depositary will deliver ADSs if the holder or broker deposits shares or evidence of rights to receive shares with the custodian. Upon payment of its fees
and expenses and of any taxes or charges, such as stamp taxes or stock transfer taxes or fees, the depositary will register the appropriate number of ADSs in
the requested names and will deliver the ADSs to or upon the order of the person or persons that made the deposit. 

ADSs may be surrendered for the purpose of withdrawal at the depositary’s office. Upon payment of its fees and expenses and of any taxes or charges, such
as stamp taxes or stock transfer taxes or fees, the depositary will deliver the shares and any other deposited securities underlying the ADSs to the ADS
holder or a person the ADS holder designates at the office of the custodian. The depositary may charge a fee and its expenses for instructing the custodian
regarding delivery of deposited securities.

An ADR may be surrendered to the depositary for the purpose of exchanging an ADR for uncertificated ADSs. The depositary will cancel that ADR and
will send to the ADS holder a statement confirming that the ADS holder is the registered holder of uncertificated ADSs. Upon receipt by the depositary of a
proper instruction from a registered holder of uncertificated ADSs requesting the exchange of uncertificated ADSs for certificated ADSs, the depositary
will executed and deliver to the ADS holder an ADR evidencing those ADSs.

Voting Rights

ADS holders may instruct the depositary how to vote the number of deposited shares their ADSs represent. If we request the depositary to solicit voting
instructions (and we are not required to do so), the depositary will notify ADS holders of a shareholders’ meeting and send or make voting materials
available. Those materials will describe the matters to be voted on and explain how ADS holders may instruct the depositary how to vote. For instructions
to be valid, they much reach the depositary by a date set by the depositary. The depositary will try, as far as practical, subject to the laws of Ireland and the
provisions of our articles of association or similar documents, to vote or to have its agents vote the shares or other deposited securities as instructed by ADS
holders. If we do not request the depositary to solicit voting instructions, ADS holders can still send voting instructions, and, in that case, the depositary
may try to vote as instructed, but it is not required to do so.

Except by instructing the depositary as described above, ADS holders will not be able to exercise voting rights unless they surrender their ADSs and
withdraw the shares. However, there may not be enough advance notice of a meeting to withdraw the shares in time. In any event, the depositary will not
exercise any discretion in voting deposited securities and it will only vote or attempt to vote as instructed or as described in the following sentence. If we
asked the depositary to solicit voting instructions at least 30 days before the meeting date but the depositary does not receive voting instructions from an
ADS holder by the specified date, this will be considered authorization and direction to give a discretionary proxy to a person designated by us to vote that
number of deposited securities. The depositary will give a discretionary proxy in those circumstances to vote on all questions at to be voted upon unless we
notify the depositary that:

 
 
 
  
  
  
 
  
 
 
·

·

·

we do not wish to receive a discretionary proxy;

there is substantial shareholder opposition to the particular question; or

the particular question would have an adverse impact on our shareholders.

We are required to notify the depositary if one of the conditions specified above exists.

We cannot assure that ADS holders will receive the voting materials in time to ensure that they can instruct the depositary to vote their shares. 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.

In order to give you a reasonable opportunity to instruct the depositary as to the exercise of voting rights relating to Deposited Securities, if we request the
Depositary to act, we agree to give the depositary notice of any such meeting and details concerning the matters to be voted upon at least 30 days in
advance of the meeting date.

Fees and Expenses

Persons depositing or withdrawing shares or ADS holders
must pay:

$5.00 (or less) per 100 ADSs (or portion of 100 ADSs)

For:

Issuance of ADSs, including issuances resulting from a distribution of shares
or rights or other property

Cancellation of ADSs for the purpose of withdrawal, including if the deposit
agreement terminates

$.05 (or less) per ADS

Any cash distribution to ADS holders

A fee equivalent to the fee that would be payable if securities
distributed to you had been shares and the shares had been
deposited for issuance of ADSs

Distribution of securities distributed to holders of deposited securities (including rights)
that are distributed by the depositary to ADS holders

$.05 (or less) per ADS per calendar year

Depositary services

Registration or transfer fees

Expenses of the depositary

Transfer and registration of shares on our share register to or from the name of the
depositary or its agent when you deposit or withdraw shares

Cable, telex and facsimile transmissions (when expressly provided in the
deposit agreement)

converting foreign currency to U.S. dollars

As necessary

Taxes and other governmental charges the depositary or the
custodian has to pay on any ADSs or shares underlying ADSs,
such as stock transfer taxes, stamp duty or withholding taxes

Any charges incurred by the depositary or its agents for
servicing the deposited securities

As necessary

The depositary collects its fees for delivery and surrender of ADSs directly from investors depositing shares or surrendering ADSs for the purpose of
withdrawal or from intermediaries acting for them. The depositary collects fees for making distributions to investors by deducting those fees from the
amounts distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its annual fee for depositary services by
deduction from cash distributions or by directly billing investors or by charging the book-entry system accounts of participants acting for them. The
depositary may collect any of its fees by deduction from any cash distribution payable (or by selling a portion of securities or other property distributable)
to ADS holders that are obligated to pay those fees. The depositary may generally refuse to provide fee-attracting services until its fees for those services
are paid.

From time to time, the depositary may make payments to us to reimburse us for costs and expenses generally arising out of

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
establishment and maintenance of the ADS program, waive fees and expenses for services provided to us by the depositary or share revenue from the fees
collected from ADS holders. In performing its duties under the deposit agreement, the depositary may use brokers, dealers, foreign currency dealers or
other service providers that are owned by or affiliated with the depositary and that may earn or share fees, spreads or commissions.

The depositary may convert currency itself or through any of its affiliates and, in those cases, acts as principal for its own account and not as agent, advisor,
broker or fiduciary on behalf of any other person and earns revenue, including, without limitation, transaction spreads, that it will retain for its own
account. The revenue is based on, among other things, the difference between the exchange rate assigned to the currency conversion made under the
deposit agreement and the rate that the depositary or its affiliate receives when buying or selling foreign currency for its own account. The depositary
makes no representation that the exchange rate used or obtained in any currency conversion under the deposit agreement will be the most favorable rate that
could be obtained at the time or that the method by which that rate will be determined will be the most favorable to ADS holders, subject to the depositary’s
obligations under the deposit agreement. The methodology used to determine exchange rates used in currency conversions is available upon request.

Payment of Taxes

ADS holders are responsible for any taxes or other governmental charges payable on their ADSs or on the deposited securities represented by any of their
ADSs. The depositary may refuse to register any transfer of ADSs or withdrawal requests of the deposited securities represented by ADSs until those taxes
or other charges are paid. It may apply payments owed to the ADS holder or sell deposited securities represented by the holder’s ADSs to pay any taxes
owed and the holder will remain liable for any deficiency. If the depositary sells deposited securities, it will, if appropriate, reduce the number of ADSs to
reflect the sale and pay to ADS holders any proceeds, or send to ADS holders any property, remaining after it has paid the taxes. 

Tender and Exchange Offers; Redemption, Replacement or Cancellation of Deposited Securities

The depositary will not tender deposited securities in any voluntary tender or exchange offer unless instructed to do by an ADS holder surrendering ADSs
and subject to any conditions or procedures the depositary may establish.

If deposited securities are redeemed for cash in a transaction that is mandatory for the depositary as a holder of deposited securities, the depositary will call
for surrender of a corresponding number of ADSs and distribute the net redemption money to the holders of called ADSs upon surrender of those ADSs.

If there is any change in the deposited securities such as a sub-division, combination or other reclassification, or any merger, consolidation, recapitalization
or reorganization affecting the issuer of deposited securities in which the depositary receives new securities in exchange for or in lieu of the old deposited
securities, the depositary will hold those replacement securities as deposited securities under the deposit agreement. However, if the depositary decides it
would not be lawful and to hold the replacement securities because those securities could not be distributed to ADS holders or for any other reason, the
depositary may instead sell the replacement securities and distribute the net proceeds upon surrender of the ADSs.

If there is a replacement of the deposited securities and the depositary will continue to hold the replacement securities, the depositary may distribute new
ADSs representing the new deposited securities or request the surrender of outstanding ADRs in exchange for new ADRs identifying the new deposited
securities.

If there are no deposited securities underlying ADSs, including if the deposited securities are cancelled, or if the deposited securities underlying ADSs have
become apparently worthless, the depositary may call for surrender or of those ADSs or cancel those ADSs upon notice to the ADS holders.

Amendment and Termination

We may agree with the depositary to amend the deposit agreement and the ADRs without ADS holders’ consent for any reason. If an amendment adds or
increases fees or charges, except for taxes and other governmental charges or expenses of the depositary for registration fees, facsimile costs, delivery
charges or similar items, or prejudices a substantial right of ADS holders, it will not become effective for outstanding ADSs until 30 days after the
depositary notifies ADS holders of the amendment. At the time an amendment becomes effective, ADS holders, by continuing to hold ADSs, are considered
to agree to the amendment and to be bound by the ADRs and the deposit agreement as amended.

The depositary will initiate termination of the deposit agreement if we instruct it to do so. The depositary may initiate

 
 
 
 
 
 
 
 
 
 
  
  
termination of the deposit agreement if

60 days have passed since the depositary told us it wants to resign but a successor depositary has not been appointed and accepted its
appointment;

we delist the ADSs from an exchange on which they were listed and do not list the ADSs on another exchange;

we appear to be insolvent or enter insolvency proceedings

all or substantially all the value of the deposited securities has been distributed either in cash or in the form of securities;

there are no deposited securities underlying the ADSs or the underlying deposited securities have become apparently worthless; or

there has been a replacement of deposited securities.

·

·

·

·

·

·

If the deposit agreement will terminate, the depositary will notify ADS holders at least 90 days before the termination date. At any time after the
termination date, the depositary may sell the deposited securities. After that, the depositary will hold the money it received on the sale, as well as any other
cash it is holding under the deposit agreement, unsegregated and without liability for interest, for the pro rata benefit of the ADS holders that have not
surrendered their ADSs. Normally, the depositary will sell as soon as practicable after the termination date.

After the termination date and before the depositary sells, ADS holders can still surrender their ADSs and receive delivery of deposited securities, except
that the depositary may refuse to accept a surrender for the purpose of withdrawing deposited securities if it would interfere with the selling process. The
depositary may refuse to accept a surrender for the purpose of withdrawing sale proceeds until all the deposited securities have been sold. The depositary
will continue to collect distributions on deposited securities, but, after the termination date, the depositary is not required to register any transfer of ADSs or
distribute any dividends or other distributions on deposited securities to the ADSs holder (until they surrender their ADSs) or give any notices or perform
any other duties under the deposit agreement except as described in this paragraph.

Limitations on Obligations and Liability

Limits on our Obligations and the Obligations of the Depositary; Limits on Liability to Holders of ADSs

The deposit agreement expressly limits our obligations and the obligations of the depositary. It also limits our liability and the liability of the depositary. We
and the depositary:

·

·

·

·

are only obligated to take the actions specifically set forth in the deposit agreement without negligence or bad faith;

are not liable if we are or it is prevented or delayed by law or circumstances beyond our or its control from performing our or its obligations
under the deposit agreement;

are not liable if we or it exercises discretion permitted under the deposit agreement;

are not liable for the inability of any holder of ADSs to benefit from any distribution on deposited securities that is not made available to
holders of ADSs under the terms of the deposit agreement, or for any special, consequential or punitive damages for any breach of the
terms of the deposit agreement;

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
have no obligation to become involved in a lawsuit or other proceeding related to the ADSs or the deposit agreement on the ADS holder’s
behalf or on behalf of any other person;

the depositary has no duty to make any determination or provide any information as to our tax status, or any liability for any tax
consequences that may be incurred by ADS holders as a result of owning or holding ADSs;

are not liable for the acts or omissions of any securities depository, clearing agency or settlement system; and

may rely upon any documents we believe or it believes in good faith to be genuine and to have been signed or presented by the proper
person.

·

·

·

·

In the deposit agreement, we and the depositary agree to indemnify each other under certain circumstances.

Requirements for Depositary Actions

Before the depositary will deliver or register a transfer of ADSs, make a distribution on ADSs, or permit withdrawal of shares, the depositary may require:

payment  of  stock  transfer  or  other  taxes  or  other  governmental  charges  and  transfer  or  registration  fees  charged  by  third  parties  for  the
transfer of any shares or other deposited securities;

satisfactory proof of the identity and genuineness of any signature or other information it deems necessary; and

compliance  with  regulations  it  may  establish,  from  time  to  time,  consistent  with  the  deposit  agreement,  including  presentation  of  transfer
documents.

·

·

·

The depositary may refuse to deliver ADSs or register transfers of ADSs when the transfer books of the depositary or our transfer books are closed or at
any time if the depositary or we think it advisable to do so.

Right to Receive the Shares Underlying ADSs

ADS holders have the right to cancel their ADSs and withdraw the underlying shares at any time except:

when temporary delays arise because: (i) the depositary has closed its transfer books or we have closed our transfer books; (ii) the transfer of
shares is blocked to permit voting at a shareholders' meeting; or (iii) we are paying a dividend on our shares;

when the ADS holder owes money to pay fees, taxes and similar charges; or

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 shares or other deposited securities.

·

·

·

This right of withdrawal may not be limited by any other provision of the deposit agreement.

Direct Registration System

In the deposit agreement, all parties to the deposit agreement acknowledge that the Direct Registration System, also referred to as DRS, and Profile
Modification System, also referred to as Profile, will apply to the ADSs. DRS is a system administered by DTC that facilitates interchange between
registered holding of uncertificated ADSs and holding of security entitlements in ADSs through DTC and a DTC participant. Profile is a feature of DRS
that allows a DTC participant, claiming to act on behalf

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
of a registered holder of uncertificated ADSs, to direct the depositary to register a transfer of those ADSs to DTC or its nominee and to deliver those ADSs
to the DTC account of that DTC participant without receipt by the depositary of prior authorization from the ADS holder to register that transfer.

In connection with and in accordance with the arrangements and procedures relating to DRS/Profile, the parties to the deposit agreement understand that
the depositary will not determine whether the DTC participant that is claiming to be acting on behalf of an ADS holder in requesting registration of transfer
and delivery as described in the paragraph above has the actual authority to act on behalf of the ADS holder (notwithstanding any requirements under the
Uniform Commercial Code). In the deposit agreement, the parties agree that the depositary’s reliance on and compliance with instructions received by the
depositary through the DRS/Profile system and in accordance with the deposit agreement will not constitute negligence or bad faith on the part of the
depositary.

Shareholder communications; inspection of register of holders of ADSs

The depositary will make available for inspection at its office all communications that it receives from us as a holder of deposited securities that we make
generally available to holders of deposited securities. The depositary will send copies of those communications or otherwise make those communications
available to ADS holders if we ask it to. ADS holders have a right to inspect the register of holders of ADSs, but not for the purpose of contacting those
holders about a matter unrelated to our business or the ADSs.

Jury Trial Waiver

The deposit agreement provides that, to the extent permitted by law, ADS holders waive the right to a jury trial of any claim they may have against us or
the depositary arising out of or relating to our shares, the ADSs or the deposit agreement, including any claim under the U.S. federal securities laws. If we
or the depositary opposed a jury trial demand based on the waiver, the court would determine whether the waiver was enforceable in the facts and
circumstances of that case in accordance with applicable case law.

ADS holders will not, by agreeing to the terms of the deposit agreement, be deemed to have waived our or the depositary’s compliance with U.S. Securities
Act of 1933 or the rules and regulations promulgated thereunder.

2.
(a)

Registration.
On  or  prior  to  the  Filing  Deadline,  the  Company  shall  prepare  and  file  with  the  Commission  a
Registration  Statement  covering  the  resale  of  all  of  the  Registrable  Securities  not  then  registered  on  an  existing  and  effective
Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415 or, if Rule 415 is not available for
offers and sales of the Registrable Securities, by such other means of distribution of Registrable Securities as the Holders may
reasonably specify (the “Initial Registration

Statement”).  The  Initial  Registration  Statement  shall  be  on  Form  S-3  (except  if  the  Company  is  then  ineligible  to  register  for
resale the Registrable Securities on Form S-3, in which case such registration shall be on such other form available to register for
resale  the  Registrable  Securities  as  a  secondary  offering)  subject  to  the  provisions  of  Section 2(d)  and  shall  contain  (except  if
otherwise required pursuant to written comments received from the Commission upon a review of such Registration Statement)
the “Plan of Distribution” section substantially in the form attached hereto as Annex A (which may be modified to respond to
comments, if any, provided by the Commission). Notwithstanding the registration obligations set forth in this Section 2,  in  the
event the Commission informs the Company that all of the Registrable Securities cannot, as a result of the application of Rule
415, be registered for resale as a secondary offering on a single registration statement, the Company agrees to promptly (i) inform
each of the Holders thereof and use its reasonable best efforts to file amendments to the Initial Registration Statement as required
by  the  Commission  and/or  (ii)  withdraw  the  Initial  Registration  Statement  and  file  a  new  registration  statement  (a  “New
Registration Statement”), in either case covering the maximum number of Registrable Securities permitted to be registered by the
Commission, on Form S-3 or, if the Company is ineligible to register the Registrable Securities on Form S-3, such other form
available  to  register  for  resale  the  Registrable  Securities  as  a  secondary  offering;  provided,  however,  that  prior  to  filing  such
amendment or New Registration Statement, the Company shall be obligated to use its reasonable best efforts to advocate with the
Commission  for  the  registration  of  all  of  the  Registrable  Securities  in  accordance  with  the  SEC  Guidance,  including  without
limitation, the Securities Act Rules Compliance and Disclosure Interpretations Question 612.09. Each Purchaser shall have the right
to  comment  or  have  their  counsel  comment  on  any  written  submission  made  to  the  staff  of  Commission  (the  “Staff”)  with  respect  to  any
disclosure specifically relating to such Purchaser. No such written submission shall be made to the Staff containing disclosure specifically
relating  to  such  Purchaser  to  which  such  Purchaser's  counsel  reasonably  objects.  Notwithstanding  any  other  provision  of  this
Agreement, if any SEC Guidance sets forth a limitation of the number of Registrable Securities permitted to be registered on a
particular Registration Statement as a secondary offering (and notwithstanding that the Company used reasonable best efforts to
advocate with the Commission for the registration of all or a greater number of Registrable Securities), unless otherwise directed
in writing by a Holder as to its Registrable Securities, the number of Registrable Securities to be registered on such Registration
Statement will first be reduced by Registrable Securities not acquired pursuant to the Purchase Agreement (whether pursuant to
registration  rights  or  otherwise),  and  second  by  Registrable  Securities  represented  by  Shares  (applied,  in  the  case  that  some
Shares  may  be  registered,  to  the  Holders  on  a  pro  rata  basis  based  on  the  total  number  of  unregistered  Shares  held  by  such
Holders, subject to a determination by the Commission that certain Holders must be reduced first based on the number of Shares
held by such Holders). In the event the Company amends the Initial Registration Statement or files a New Registration Statement,
as the case may be, under clauses (i) or (ii) above, the Company will use its reasonable best efforts to file with the Commission,
as promptly as allowed by Commission or SEC Guidance provided to the Company or to registrants of securities in general, one
or more registration statements on Form S-3 or such other form available to register for resale those Registrable Securities that
were  not  registered  for  resale  on  the  Initial  Registration  Statement,  as  amended,  or  the  New  Registration  Statement  (the
“Remainder Registration Statements”).

(b)

The Company shall use its reasonable best efforts to cause each Registration Statement to be declared effective by
the  Commission  as  soon  as  practicable  and,  with  respect  to  the  Initial  Registration  Statement  or  the  New  Registration  Statement,  as
applicable,  no  later  than  the  Effectiveness  Deadline  (including  filing  with  the  Commission  a  request  for  acceleration  of  effectiveness  in
accordance with Rule 461 promulgated under the Securities Act), and shall use its reasonable best efforts to keep each Registration Statement
continuously  effective  under  the  Securities  Act  for  so  long  as  the  securities  registered  for  resale  thereunder  retain  their  character  as
Registrable Securities (the “Effectiveness Period”). The Company shall request effectiveness of a Registration Statement as of 4:00 P.M. New
York City time on a Trading Day. The Company shall promptly notify the Holders via e-mail of the effectiveness of a Registration Statement
or  any  post-effective  amendment  thereto  on  the  same  Trading  Day  that  the  Company  telephonically  confirms  effectiveness  with  the
Commission, which date of confirmation shall initially be the date

requested for effectiveness of such Registration Statement. The Company shall, by 9:30 A.M. New York City time on the first Trading Day
after the Effective Date, file a final Prospectus with the Commission, as required by Rule 424(b).

(c)

Each Holder agrees to furnish to the Company a completed Selling Shareholder Questionnaire not more than five
(5)  Trading  Days  following  the  date  of  this  Agreement.  At  least  ten  (10)  Trading  Days  prior  to  the  first  anticipated  filing  date  of  a
Registration  Statement  for  any  registration  under  this  Agreement,  the  Company  will  notify  each  Holder  of  the  information  the  Company
requires from that Holder other than the information contained in the Selling Shareholder Questionnaire, if any, which shall be completed and
delivered to the Company promptly upon request and, in any event, within three (3) Trading Days prior to the applicable anticipated filing
date. Each Holder further agrees that it shall not be entitled to be named as a selling securityholder in the Registration Statement or use the
Prospectus  for  offers  and  resales  of  Registrable  Securities  at  any  time,  unless  such  Holder  has  returned  to  the  Company  a  completed  and
signed  Selling  Shareholder  Questionnaire  and  a  response  to  any  reasonable  requests  for  further  information  as  described  in  the  previous
sentence. If a Holder of Registrable Securities returns a Selling Shareholder Questionnaire or a request for further information, in either case,
after its respective deadline, the Company shall use its reasonable best efforts to take such actions as are required to name such Holder as a
selling security holder in the Registration Statement or any pre-effective or post-effective amendment thereto and to include (to the extent not
theretofore  included)  in  the  Registration  Statement  the  Registrable  Securities  identified  in  such  late  Selling  Shareholder  Questionnaire  or
request  for  further  information.  Each  Holder  acknowledges  and  agrees  that  the  information  in  the  Selling  Shareholder  Questionnaire  or
request for further information as described in this Section 2(d) will be used by the Company in the preparation of the Registration Statement
and hereby consents to the inclusion of such information in the Registration Statement.

(d)

In the event that Form S-3 is not available for the registration of the resale of Registrable Securities hereunder, the
Company shall (i) register the resale of the Registrable Securities on another appropriate form reasonably acceptable to the Holders and (ii)
undertake to register the Registrable Securities on Form S-3 promptly after such form is available, provided that the Company shall maintain
the  effectiveness  of  the  Registration  Statement  then  in  effect  until  such  time  as  a  Registration  Statement  on  Form  S-3  covering  the
Registrable Securities has been declared effective by the Commission.

3.

Registration Procedures

In connection with the Company's registration obligations hereunder, the Company shall:

(a)

Not less than five (5) Trading Days prior to the filing of each Registration Statement and not less than one
(1) Trading Day prior to the filing of any related Prospectus or any amendment or supplement thereto (except for Annual Reports on
Form 10-K, and Quarterly Reports on Form 10-Q and Current Reports on Form 8-K and any similar or successor reports), (i) furnish
to  each  Holder  copies  of  such  Registration  Statement,  Prospectus  or  amendment  or  supplement  thereto,  as  proposed  to  be  filed,
which documents will be subject to the review of such Holder (it being acknowledged and agreed that if a Holder does not object to
or comment on the aforementioned documents within such five (5) Trading Day or one (1) Trading Day period, as the case may be,
then the Holder shall be deemed to have consented to and approved the use of such documents) and (ii) use reasonable best efforts to
cause  its  officers  and  directors,  counsel  and  independent  registered  public  accountants  to  respond  to  such  inquiries  as  shall  be
necessary, in the reasonable opinion of respective counsel to each Holder, to conduct a reasonable investigation within the meaning
of the Securities Act. The Company shall not file any Registration Statement or amendment or supplement thereto in a form to which
a  Holder  reasonably  objects  in  good  faith,  provided  that,  the  Company  is  notified  of  such  objection  in  writing  within  the  five  (5)
Trading Day or one (1) Trading Day period described above, as applicable.

(b)

(i)  Prepare  and  file  with  the  Commission  such  amendments  (including  post‑effective  amendments)  and
supplements, to each Registration Statement and the Prospectus used in connection therewith as may be necessary to keep such Registration
Statement continuously effective as to the applicable Registrable Securities for its Effectiveness Period; (ii) cause the related Prospectus to be
amended  or  supplemented  by  any  required  Prospectus  supplement  (subject  to  the  terms  of  this  Agreement),  and,  as  so  supplemented  or
amended, to be filed pursuant to Rule 424; (iii) respond as promptly as reasonably possible to any comments received from the Commission
with respect to each Registration Statement or any amendment thereto and, as promptly as reasonably possible, notify the Holders of such
comments and provide the Holders true and complete copies of all correspondence from and to the Commission relating to such Registration
Statement that pertains to the Holders as “Selling Stockholders” but not any comments

that would result in the disclosure to the Holders of material and non-public information concerning the Company; and (iv) comply with the
provisions of the Securities Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by a Registration
Statement  until  such  time  as  all  of  such  Registrable  Securities  shall  have  been  disposed  of  (subject  to  the  terms  of  this  Agreement)  in
accordance with the intended methods of disposition by the Holders thereof as set forth in such Registration Statement as so amended or in
such Prospectus as so supplemented; provided, however, that each Purchaser shall be responsible for the delivery of the Prospectus to the
Persons  to  whom  such  Purchaser  sells  any  of  the  Shares  (including  in  accordance  with  Rule  172  under  the  Securities  Act),  and  each
Purchaser agrees to dispose of Registrable Securities in compliance with the “Plan of Distribution” described in the Registration Statement
and otherwise in compliance with applicable federal and state securities laws. In the case of amendments and supplements to a Registration
Statement which are required to be filed pursuant to this Agreement (including pursuant to this Section 3(b)) by reason of the Company filing
a report on Form 10-K, Form 10-Q or Form 8-K or any analogous report under the Exchange Act, the Company shall have incorporated such
report by reference into such Registration Statement, if applicable, or shall file such amendments or supplements with the Commission on the
same  day  on  which  the  Exchange  Act  report  which  created  the  requirement  for  the  Company  to  amend  or  supplement  such  Registration
Statement was filed.

(c)

Notify  the  Holders  (which  notice  shall,  pursuant  to  clauses  (iii)  through  (vi)  hereof,  be  accompanied  by  an
instruction to suspend the use of the Prospectus until the requisite changes have been made) as promptly as reasonably possible (and, in the
case of (i)(A) below, not less than one (1) Trading Day prior to such filing) and confirm such notice in writing no later than one (1) Trading
Day following the day: (i)(A) when a Prospectus or any Prospectus supplement or post‑effective amendment to a Registration Statement is
proposed to be filed; (B) when the Commission notifies the Company whether there will be a “review” of such Registration Statement and
whenever  the  Commission  comments  in  writing  on  any  Registration  Statement  (in  which  case  the  Company  shall  provide  to  each  of  the
Holders true and complete copies of all comments that pertain to the Holders as a “Selling Stockholder” or to the “Plan of Distribution” and
all written responses thereto, but not information that the Company believes would constitute material and non-public information); and (C)
with respect to each Registration Statement or any post‑effective amendment, when the same has become effective; (ii) of any request by the
Commission or any other Federal or state governmental authority for amendments or supplements to a Registration Statement or Prospectus
or for additional information that pertains to the Holders as “Selling Stockholders” or the “Plan of Distribution”; (iii) of the issuance by the
Commission or any other federal or state governmental authority of any stop order suspending the effectiveness of a Registration Statement
covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose; (iv) of the receipt by the Company of
any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for
sale in any jurisdiction, or the initiation or threatening of any Proceeding for such purpose; (v) of the occurrence of any event or passage of
time  that  makes  the  financial  statements  included  or  incorporated  by  reference  in  a  Registration  Statement  ineligible  for  inclusion  or
incorporation  by  reference  therein  or  any  statement  made  in  such  Registration  Statement  or  Prospectus  or  any  document  incorporated  or
deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to such Registration Statement,
Prospectus or other documents so that, in the case of such Registration Statement or the Prospectus, as the case may be, it will not contain
any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements
therein (in the case of any Prospectus, form of prospectus or supplement thereto, in light of the circumstances under which they were made),
not misleading and (vi) of the occurrence or existence of any pending corporate development with respect to the Company that the Company
reasonably believes may be material and that, in the good faith determination of the Board of Directors, would be materially detrimental to
the  Company  to  allow  continued  availability  of  a  Registration  Statement  or  Prospectus,  provided  that,  any  and  all  such  information  shall
remain confidential to each Holder until such information otherwise becomes public, unless disclosure by a Holder is required by law; and
provided,  further,  that  notwithstanding  each  Holder’s  agreement  to  keep  such  information  confidential,  each  such  Holder  makes  no
acknowledgement that any such information is material, non-public information.

(d)

Use  reasonable  best  efforts  to  avoid  the  issuance  of,  or,  if  issued,  obtain  the  withdrawal  of  (i)  any  order
suspending the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any
of the Registrable Securities for sale in any jurisdiction, as soon as possible.

(e)

Furnish  to  such  Holder,  without  charge,  at  least  one  conformed  copy  of  each  Registration  Statement  and  each
amendment  thereto  and  all  exhibits  to  the  extent  requested  by  such  Person  (including  those  previously  furnished  or  incorporated  by
reference) promptly after the filing of such documents with the Commission;

provided, that the Company shall have no obligation to provide any document pursuant to this clause that is available on the Commission’s
EDGAR system.

(f)

Promptly  deliver  to  the  Holders,  without  charge,  as  many  copies  of  each  Prospectus  or  Prospectuses  (including
each form of prospectus) and each amendment or supplement thereto as such Person may reasonably request. The Company hereby consents
to the use of such Prospectus and each amendment or supplement thereto by each of the selling Holders in connection with the offering and
sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto.

(g)

Prior to any resale of Registrable Securities by a Holder, use its reasonable best efforts to register or qualify or
cooperate with the selling Holders in connection with the registration or qualification (or exemption from the registration or qualification) of
such Registrable Securities for the resale by the Holder under the securities or Blue Sky laws of such jurisdictions within the United States as
any  Holder  reasonably  requests  in  writing,  to  keep  each  registration  or  qualification  (or  exemption  therefrom)  effective  during  the
Effectiveness  Period  and  to  do  any  and  all  other  acts  or  things  reasonably  necessary  or  advisable  to  enable  the  disposition  in  such
jurisdictions  of  the  Registrable  Securities  covered  by  each  Registration  Statement;  provided,  that  the  Company  shall  not  be  required  to
qualify generally to do business in any jurisdiction where it is not then so qualified, subject the Company to any material tax in any such
jurisdiction where it is not then so subject or file a general consent to service of process in any such jurisdiction.

(h)

Cooperate  with  such  Holder  to  facilitate  the  timely  preparation  and  delivery  of  certificates  or  book  entry
statements,  as  applicable,  representing  Registrable  Securities  to  be  delivered  to  a  transferee  pursuant  to  the  Registration  Statement,  which
certificates or statements shall be free, to the extent permitted by the Purchase Agreement and under law, of all restrictive legends, and to
enable such Registrable Securities to be in such denominations and registered in such names as any such Holders may request.

(i)

Following the occurrence of any event contemplated by Section 3(c), as promptly as reasonably possible (taking
into  account  the  Company’s  good  faith  assessment  of  any  adverse  consequences  to  the  Company  and  its  shareholders  of  the  premature
disclosure of such event), prepare a supplement or amendment, including a post‑effective amendment, to the affected Registration Statements
or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other
required  document  so  that,  as  thereafter  delivered,  no  Registration  Statement  nor  any  Prospectus  will  contain  an  untrue  statement  of  a
material  fact  or  omit  to  state  a  material  fact  required  to  be  stated  therein  or  necessary  to  make  the  statements  therein  (in  the  case  of  any
Prospectus,  form  of  prospectus  or  supplement  thereto,  in  light  of  the  circumstances  under  which  they  were  made),  not  misleading.  If  the
Company notifies the Holders in accordance with clauses (iii) through (vi) of Section 3(c) above to suspend the use of any Prospectus until
the requisite changes to such Prospectus have been made, then the Holders shall suspend use of such Prospectus. The Company will use its
reasonable best efforts to ensure that the use of the Prospectus may be resumed as promptly as is practicable. The Company shall be entitled
to exercise its right under this Section 3(i) to suspend the availability of a Registration Statement and Prospectus. For the avoidance of doubt,
any  period  of  time  for  which  the  availability  of  a  Registration  Statement  and  Prospectus  are  suspended  pursuant  to  Section  2(d)  shall  be
disregarded when determining the time period allotted under this Section 3(i).

(j)

The Company may require each selling Holder to furnish to the Company a certified statement as to (i) the number
of Ordinary Shares or ADSs beneficially owned by such Holder and any Affiliate thereof, (ii) any Financial Industry Regulatory Authority
(“FINRA”) affiliations, (iii) any natural persons who have the power to vote or dispose of the Ordinary Shares or ADSs and (iv) any other
information as may be requested by the Commission, FINRA or any state securities commission.

(k)

The Company shall cooperate with any registered broker through which a Holder proposes to resell its Registrable
Securities in effecting a filing with FINRA pursuant to FINRA Rule 5110 as requested by any such Holder and the Company shall pay the
filing fee required for the first such filing within two (2) Business Days of the request therefor.

4.

Registration Expenses. All fees and expenses incident to the Company’s performance of or compliance with its obligations
under this Agreement (excluding any underwriting discounts and selling commissions and all legal fees and expenses of legal counsel for any
Holder) shall be borne by the Company whether or not any Registrable Securities are sold pursuant to a Registration Statement. The fees and
expenses  referred  to  in  the  foregoing  sentence  shall  include,  without  limitation,  (i)  all  registration  and  filing  fees  (including,  without

disbursements of counsel for the Company in connection with Blue Sky qualifications or exemptions of the

Registrable Securities and determination of the eligibility of the Registrable Securities for investment under the laws of such jurisdictions as
requested by the Holders) and (C) if not previously paid by the Company in connection with Section 3(j) above, with respect to any filing
that may be required to be made by any broker through which a Holder intends to make sales of Registrable Securities with FINRA pursuant
to the FINRA Rule 5110, so long as the broker is receiving no more than a customary brokerage commission in connection with such sale,
(ii) printing expenses (including, without limitation, expenses of printing certificates for Registrable Securities and of printing prospectuses if
the printing of prospectuses is reasonably requested by the Holders of a majority of the Registrable Securities included in the Registration
Statement),  (iii)  messenger,  telephone  and  delivery  expenses,  (iv)  fees  and  disbursements  of  counsel  for  the  Company,  (v)  Securities  Act
liability insurance, if the Company so desires such insurance, and (vi) fees and expenses of all other Persons retained by the Company in

of  its  internal  expenses  incurred  in  connection  with  the  consummation  of  the  transactions  contemplated  by  this  Agreement  (including,

indemnify, defend and hold harmless each Holder, the officers, directors, agents, partners, members, managers, stockholders, Affiliates and

of the Exchange Act) and the officers, directors, partners, members, managers, stockholders, agents and employees of each such controlling

Prospectus  or  any  form  of  prospectus  or  in  any  amendment  or  supplement  thereto  or  in  any  preliminary  prospectus,  or  arising  out  of  or
relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein
(in the case of any Prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not
misleading, or (ii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act or any state securities law or
any rule or regulation thereunder, in connection with the performance of its obligations under this Agreement, except to the extent, but only
to the extent, that (A) such untrue statements, alleged untrue statements, omissions or alleged omissions are based solely upon information
regarding such Holder furnished in writing to the Company by such Holder expressly for use therein, or to the extent that such information
relates to such Holder or such Holder's proposed method of distribution of Registrable Securities and was reviewed and approved in writing
by  such  Holder  expressly  for  use  in  the  Registration  Statement,  such  Prospectus  or  such  form  of  Prospectus  or  in  any  amendment  or
supplement thereto (it being understood that each Holder has approved Annex A hereto for this purpose) or (B) in the case of an occurrence
of  an  event  of  the  type  specified  in  Section 3(c)(iii)-(vi),  related  to  the  use  by  a  Holder  of  an  outdated  or  defective  Prospectus  after  the
Company  has  notified  such  Holder  in  writing  that  the  Prospectus  is  outdated  or  defective  and  prior  to  the  receipt  by  such  Holder  of  the
Advice contemplated and defined in Section 6(d) below, to the extent that following the receipt of the Advice the misstatement or omission
giving  rise  to  such  Loss  would  have  been  corrected  or  (C)  to  the  extent  that  any  such  Losses  arise  out  of  the  Purchaser’s  (or  any  other
indemnified  Person’s)  failure  to  send  or  give  a  copy  of  the  Prospectus  or  supplement  (as  then  amended  or  supplemented),  if  required,
pursuant to Rule 172 under the Securities Act (or any successor rule) to the Persons asserting an untrue statement or alleged untrue statement
or alleged untrue statement or omission or alleged omission at or prior to the written confirmation of the sale of Registrable Securities to such
Person if such statement or omission was corrected in such Prospectus or supplement. The Company shall notify the Holders promptly of the
institution, threat or assertion of any Proceeding arising from or in connection with the transactions contemplated by this Agreement of which
the  Company  is  aware.  Such  indemnity  shall  remain  in  full  force  and  effect  regardless  of  any  investigation  made  by  or  on  behalf  of  an
Indemnified Party (as defined in Section 5(c)) and shall survive the transfer of the Registrable Securities by the Holders.

(b)

Indemnification  by  Holders.  Each  Holder  shall,  severally  and  not  jointly,  indemnify  and  hold  harmless  the

Company, its directors, officers, agents and employees, each Person who controls the Company (within

the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such
controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses, as incurred, arising out of or are based
solely upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus, or any form of
prospectus,  or  in  any  amendment  or  supplement  thereto  or  in  any  preliminary  prospectus,  or  arising  out  of  or  relating  to  any  omission  or
alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus, or
any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading (i) to the extent that
such untrue statements or omissions are based solely upon information regarding such Holder furnished in writing to the Company by such
Holder  expressly  for  use  therein  or  (ii)  to  the  extent  that  such  information  relates  to  such  Holder  or  such  Holder’s  proposed  method  of
distribution of Registrable Securities and was reviewed and approved in writing by such Holder expressly for use in a Registration Statement
(it being understood that the Holder has approved Annex A hereto for this purpose), such Prospectus or such form of Prospectus or in any
amendment or supplement thereto or (iii) in the case of an occurrence of an event of the type specified in Section 3(c)(iii)-(vi), to the extent
related  to  the  use  by  such  Holder  of  an  outdated  or  defective  Prospectus  after  the  Company  has  notified  such  Holder  in  writing  that  the
Prospectus is outdated or defective and prior to the receipt by such Holder of the Advice contemplated in Section 6(d). In no event shall the
liability of any selling Holder hereunder be greater in amount than the dollar amount of the net proceeds received by such Holder upon the
sale of the Registrable Securities giving rise to such indemnification obligation.

(c)

Conduct  of  Indemnification  Proceedings.  If  any  Proceeding  shall  be  brought  or  asserted  against  any  Person
entitled to indemnity hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is
sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall have the right to assume the defense thereof, including the
employment  of  counsel  reasonably  satisfactory  to  the  Indemnified  Party  and  the  payment  of  all  reasonable  fees  and  expenses  incurred  in
connection with defense thereof; provided, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying
Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally determined by a court of
competent jurisdiction (which determination is not subject to appeal or further review) that such failure shall have materially and adversely
prejudiced the Indemnifying Party.

An  Indemnified  Party  shall  have  the  right  to  employ  separate  counsel  in  any  such  Proceeding  and  to  participate  in  the
defense  thereof,  but  the  fees  and  expenses  of  such  counsel  shall  be  at  the  expense  of  such  Indemnified  Party  or  Parties  unless:  (1)  the
Indemnifying Party has agreed in writing to pay such fees and expenses; (2) the Indemnifying Party shall have failed promptly to assume the
defense  of  such  Proceeding  and  to  employ  counsel  reasonably  satisfactory  to  such  Indemnified  Party  in  any  such  Proceeding;  or  (3)  the
named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and
such  Indemnified  Party  shall  have  been  advised  by  counsel  that  a  conflict  of  interest  exists  if  the  same  counsel  were  to  represent  such
Indemnified  Party  and  the  Indemnifying  Party  (in  which  case,  if  such  Indemnified  Party  notifies  the  Indemnifying  Party  in  writing  that  it
elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the
defense thereof and such counsel shall be at the expense of the Indemnifying Party); provided, that the Indemnifying Party shall not be liable
for the fees and expenses of more than one separate firm of attorneys at any time for all Indemnified Parties. The Indemnifying Party shall
not  be  liable  for  any  settlement  of  any  such  Proceeding  effected  without  its  written  consent,  which  consent  shall  not  be  unreasonably
withheld,  delayed  or  conditioned.  No  Indemnifying  Party  shall,  without  the  prior  written  consent  of  the  Indemnified  Party,  effect  any
settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an unconditional
release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding.

Subject  to  the  terms  of  this  Agreement,  all  fees  and  expenses  of  the  Indemnified  Party  (including  reasonable  fees  and
expenses to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this
Section 5) shall be paid to the Indemnified Party, as incurred, within twenty (20) Trading Days of written notice thereof to the Indemnifying
Party;  provided,  that  the  Indemnified  Party  shall  promptly  reimburse  the  Indemnifying  Party  for  that  portion  of  such  fees  and  expenses
applicable to such actions for which such Indemnified Party is finally judicially determined to not be entitled to indemnification hereunder).
The failure to deliver written notice to the Indemnifying Party within a reasonable time of the commencement of any such

action shall not relieve such Indemnifying Party of any liability to the Indemnified Party under this Section 5, except to the extent that the
Indemnifying Party is materially and adversely prejudiced in its ability to defend such action.

(d)

Contribution. If a claim for indemnification under Section 5(a)  or  5(b) is unavailable to an Indemnified
Party or insufficient to hold an Indemnified Party harmless for any Losses, then each Indemnifying Party, in lieu of indemnifying
such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses, in such
proportion  as  is  appropriate  to  reflect  the  relative  fault  of  the  Indemnifying  Party  and  Indemnified  Party  in  connection  with  the
actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault
of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in
question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has
been taken or made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid
or payable by a party as a result of any Losses shall be deemed to include, subject to the limitations set forth in this Agreement, any
reasonable attorneys' or other reasonable fees or expenses incurred by such party in connection with any Proceeding to the extent
such party would have been indemnified for such fees or expenses if the indemnification provided for in this Section 5 was available
to such party in accordance with its terms.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined
by  pro  rata  allocation  or  by  any  other  method  of  allocation  that  does  not  take  into  account  the  equitable  considerations  referred  to  in  the
immediately preceding paragraph. Notwithstanding the provisions of this Section 5(d), (A) no Holder shall be required to contribute, in the
aggregate, any amount in excess of the amount by which the net proceeds actually received by such Holder from the sale of the Registrable
Securities subject to the Proceeding exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission and (B) no contribution will be made under circumstances where
the maker of such contribution would not have been required to indemnify the Indemnified Party under the fault standards set forth
in  this  Section  5.  No  person  guilty  of  fraudulent  misrepresentation  (within  the  meaning  of  Section  11(f)  of  the  Securities  Act)  shall  be
entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

The indemnity and contribution agreements contained in this Section 5 are in addition to any liability that the Indemnifying Parties may have
to the Indemnified Parties and are not in diminution or limitation of the indemnification provisions under the Purchase Agreement.

6.
(a)

Miscellaneous.
Remedies.  In  the  event  of  a  breach  by  the  Company  or  by  a  Holder  of  any  of  their  obligations  under  this
Agreement, each Holder or the Company, as the case may be, in addition to being entitled to exercise all rights granted by law and under this
Agreement, including recovery of damages, will be entitled to specific performance of its rights under this Agreement. The Company and
each Holder agree that monetary damages would not provide adequate compensation for any losses incurred by reason of a breach by it of
any of the provisions of this Agreement and hereby further agrees that, in the event of any action for specific performance in respect of such
breach, it shall waive the defense that a remedy at law would be adequate.

(b)

No  Piggyback  on  Registrations;  Prohibition  on  Filing  Other  Registration  Statements.  Except  and  to  the  extent
specified in the Purchase Agreement, neither the Company nor any of its security holders (other than the Holders in such capacity pursuant
hereto) may include securities of the Company in a Registration Statement other than the Registrable Securities and the Company shall not
prior to the Effective Date enter into any agreement providing any such right to any of its security holders.

(c)

Compliance. Each Holder covenants and agrees that it will comply with the prospectus delivery requirements of
the Securities Act as applicable to it (unless an exemption therefrom is available) in connection with sales of Registrable Securities pursuant
to  the  Registration  Statement  and  shall  sell  the  Registrable  Securities  only  in  accordance  with  a  method  of  distribution  described  in  the
Registration Statement

(d)

Discontinued Disposition. By its acquisition of Registrable Securities, each Holder agrees that, upon receipt of a
notice from the Company of the occurrence of any event of the kind described in Section 3(c)(iii)-(vi), such Holder will forthwith discontinue
disposition of such Registrable Securities under a Registration

Statement  until  it  is  advised  in  writing  (the  “Advice”)  by  the  Company  that  the  use  of  the  applicable  Prospectus  (as  it  may  have  been
supplemented or amended) may be resumed. The Company will use its reasonable best efforts to ensure that the use of the Prospectus may be
resumed as promptly as is possible.
(e)

No Inconsistent Agreements. Neither the Company nor any of its Subsidiaries has entered, as of the date hereof,
nor shall the Company or any of its Subsidiaries, on or after the date hereof, enter into any agreement with respect to its securities, that would
have the effect of impairing the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof.

(f)

Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not
be amended, modified or supplemented, or waived unless the same shall be in writing and signed by the Company and Holders holding no
less than a majority of the then outstanding Registrable Securities, provided that any party may give a waiver as to itself. Notwithstanding the
foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders
and that does not directly or indirectly affect the rights of other Holders may be given by Holders of all of the Registrable Securities to which
such  waiver  or  consent  relates;  provided,  however,  that  the  provisions  of  this  sentence  may  not  be  amended,  modified,  or  supplemented
except in accordance with the provisions of the immediately preceding sentence.

(g)

Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder

shall be delivered as set forth in the Purchase Agreement.

(h)

Successors  and  Assigns.  This  Agreement  shall  inure  to  the  benefit  of  and  be  binding  upon  the  successors  and
permitted  assigns  of  each  of  the  parties  and  shall  inure  to  the  benefit  of  each  Holder.  Nothing  in  this  Agreement,  express  or  implied,  is
intended to confer upon any party other than the parties hereto or their respective successors and assigns any rights, remedies, obligations, or
liabilities  under  or  by  reason  of  this  Agreement,  except  as  expressly  provided  in  this  Agreement.  The  Company  may  not  assign  its  rights
(except by merger or in connection with another entity acquiring all or substantially all of the Company’s assets) or obligations hereunder
without  the  prior  written  consent  of  all  the  Holders  of  the  then  outstanding  Registrable  Securities.  Each  Holder  may  assign  its  respective
rights  hereunder  in  the  manner  and  to  the  Persons  as  permitted  under  the  Purchase  Agreement;  provided  in  each  case  that  (i)  the  Holder
agrees in writing with the transferee or assignee to assign such rights and related obligations under this Agreement, and for the transferee or
assignee  to  assume  such  obligations,  and  a  copy  of  such  agreement  is  furnished  to  the  Company  within  a  reasonable  time  after  such
assignment, (ii) the Company is, within a reasonable time after such transfer or assignment, furnished with written notice of the name and
address  of  such  transferee  or  assignee  and  the  securities  with  respect  to  which  such  registration  rights  are  being  transferred  or  assigned,
(iii) at or before the time the Company received the written notice contemplated by clause (ii) of this sentence, the transferee or assignee
agrees in writing with the Company to be bound by all of the provisions contained herein and (iv) the transferee is an “accredited investor,”
as that term is defined in Rule 501 of Regulation D.

(i)

Execution and Counterparts. This Agreement may be executed in two or more counterparts, each of which when
so executed shall be deemed to be an original and, all of which taken together shall constitute one and the same Agreement and shall become
effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not
sign the same counterpart. In the event that any signature is delivered by e-mail delivery of a “.pdf” format data file, such signature shall
create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as
if such “.pdf” signature were the original thereof.

(j)

Governing  Law.  All  questions  concerning  the  construction,  validity,  enforcement  and  interpretation  of  this

Agreement shall be determined in accordance with the provisions of the Purchase Agreement.

(k)

Cumulative  Remedies.  The  remedies  provided  herein  are  cumulative  and  not  exclusive  of  any  other  remedies

provided by law.

(l)

Severability.  If  any  term,  provision,  covenant  or  restriction  of  this  Agreement  is  held  by  a  court  of  competent
jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein
shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their good faith
reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such
term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed
the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void
or unenforceable.

(m)

Headings.  The  headings  in  this  Agreement  are  for  convenience  only  and  shall  not  limit  or  otherwise  affect  the

meaning hereof.

(n)

Independent  Nature  of  Purchasers’  Obligations  and  Rights.  The  obligations  of  each  Purchaser  under  this
Agreement are several and not joint with the obligations of any other Purchaser hereunder, and no Purchaser shall be responsible in any way
for the performance of the obligations of any other Purchaser hereunder. The decision of each Purchaser to purchase the Securities pursuant
to the Transaction Documents has been made independently of any other Purchaser. Nothing contained herein or in any other agreement or
document  delivered  at  any  closing,  and  no  action  taken  by  any  Purchaser  pursuant  hereto  or  thereto,  shall  be  deemed  to  constitute  the
Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any
way acting in concert with respect to such obligations or the transactions contemplated by this Agreement. Each Purchaser acknowledges that
no other Purchaser has acted as agent for such Purchaser in connection with making its investment hereunder and that no Purchaser will be
acting as agent of such Purchaser in connection with monitoring its investment in the Securities or enforcing its rights under the Transaction
Documents.  Each  Purchaser  shall  be  entitled  to  protect  and  enforce  its  rights,  including,  without  limitation,  the  rights  arising  out  of  this
Agreement, and it shall not be necessary for any other Purchaser to be joined as an additional party in any Proceeding for such purpose. The
Company  acknowledges  that  each  of  the  Purchasers  has  been  provided  with  the  same  Registration  Rights  Agreement  for  the  purpose  of
closing a transaction with multiple Purchasers and not because it was required or requested to do so by any Purchaser.

PLAN OF DISTRIBUTION

Annex A

We are registering the American Depositary Shares, or ADSs, which we refer to herein as Shares, issued to the selling stockholders
to permit the resale of these Shares by the holders of the Shares from time to time after the date of this prospectus. We will not receive any of
the proceeds from the sale by the selling stockholders of the Shares. We will, or will procure to, bear all fees and expenses incident to our
obligation to register the Shares.

The selling stockholders may sell all or a portion of the Shares beneficially owned by them and offered hereby from time to time
directly  or  through  one  or  more  underwriters,  broker-dealers  or  agents.  If  the  Shares  are  sold  through  underwriters  or  broker-dealers,  the
selling stockholders will be responsible for underwriting discounts or commissions or agent's commissions. The Shares may be sold on any
national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale, in the over-the-counter
market or in transactions otherwise than on these exchanges or systems or in the over-the-counter market and in one or more transactions at
fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. These
sales may be effected in transactions, which may involve crosses or block transactions. The selling stockholders may use any one or more of
the following methods when selling shares:

•
•

•
•
•
•

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block
as principal to facilitate the transaction;
purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
an exchange distribution in accordance with the rules of the applicable exchange;
privately negotiated transactions;
settlement of short sales entered into after the effective date of the registration statement of which this prospectus is a part;

    
•
•

broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;
through  the  writing  or  settlement  of  options  or  other  hedging  transactions,  whether  such  options  are  listed  on  an  options
exchange or otherwise;
a combination of any such methods of sale; and
any other method permitted pursuant to applicable law.

•
•
The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the
Securities Act, as amended, or the Securities Act, as permitted by that rule, or Section 4(a)(1) under the Securities Act, if available, rather
than under this prospectus, provided that they meet the criteria and conform to the requirements of those provisions.

Broker‑dealers  engaged  by  the  selling  stockholders  may  arrange  for  other  broker‑dealers  to  participate  in  sales.  If  the  selling
stockholders effect such transactions by selling Shares to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers
or agents may receive commissions in the form of discounts, concessions or commissions from the selling stockholders or commissions from
purchasers of the Shares for whom they may act as agent or to whom they may sell as principal. Such commissions will be in amounts to be
negotiated,  but,  except  as  set  forth  in  a  supplement  to  this  Prospectus,  in  the  case  of  an  agency  transaction  will  not  be  in  excess  of  a
customary brokerage commission in compliance with FINRA Rule 2121; and in the case of a principal transaction a markup or markdown in
compliance with FINRA IM-2121.01.

In connection with sales of the Shares or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers
or other financial institutions, which may in turn engage in short sales of the Shares in the course of hedging in positions they assume. The
selling stockholders may also sell Shares short and if such short sale shall take place after the date that this Registration Statement is declared
effective by the Commission, the selling stockholders may deliver Shares covered by this prospectus to close out short positions and to return
borrowed shares in connection with such short sales. The selling stockholders may also loan or pledge Shares to broker-dealers that in turn
may sell such shares, to the extent permitted by applicable law. The selling stockholders may also enter into option or other transactions with
broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-
dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may
resell  pursuant  to  this  prospectus  (as  supplemented  or  amended  to  reflect  such  transaction).  Notwithstanding  the  foregoing,  the  selling
stockholders have been advised that they may not use shares registered on this registration statement to cover short sales of our ADSs made
prior to the date the registration statement, of which this prospectus forms a part, has been declared effective by the SEC.

The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the Shares owned by them and, if
they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the Shares from time to time
pursuant to this prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of
1933,  amending,  if  necessary,  the  list  of  selling  stockholders  to  include  the  pledgee,  transferee  or  other  successors  in  interest  as  selling
stockholders under this prospectus. The selling stockholders also may transfer and donate the Shares in other circumstances in which case the
transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

The  selling  stockholders  and  any  broker-dealer  or  agents  participating  in  the  distribution  of  the  Shares  may  be  deemed  to  be
“underwriters” within the meaning of Section 2(11) of the Securities Act in connection with such sales. In such event, any commissions paid,
or any discounts or concessions allowed to, any such broker-dealer or agent and any profit on the resale of the shares purchased by them may
be deemed to be underwriting commissions or discounts under the Securities Act. Selling Stockholders who are "underwriters" within the
meaning  of  Section  2(11)  of  the  Securities  Act  will  be  subject  to  the  applicable  prospectus  delivery  requirements  of  the  Securities  Act
including Rule 172 thereunder and may be subject to certain statutory liabilities of, including but not limited to, Sections 11, 12 and 17 of the
Securities Act and Rule 10b-5 under the Securities Exchange Act of 1934, as amended, or the Exchange Act.

Each selling stockholder has informed the Company that it is not a registered broker-dealer and does not have any written or oral
agreement or understanding, directly or indirectly, with any person to distribute the Shares. Upon the Company being notified in writing by a
selling  stockholder  that  any  material  arrangement  has  been  entered  into  with  a  broker-dealer  for  the  sale  of  ADSs  through  a  block  trade,
special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer, a supplement to this prospectus will be
filed,  if  required,  pursuant  to  Rule  424(b)  under  the  Securities  Act,  disclosing  (i)  the  name  of  each  such  selling  stockholder  and  of  the
participating broker-dealer(s), (ii) the number of shares involved, (iii) the price at which such the Shares were sold, (iv) the commissions paid
or  discounts  or  concessions  allowed  to  such  broker-dealer(s),  where  applicable,  (v)  that  such  broker-dealer(s)  did  not  conduct  any
investigation to verify the information set out or incorporated by reference in this prospectus, and (vi) other facts material to the transaction.
In no event shall any broker-dealer receive fees, commissions and markups, which, in the aggregate, would exceed eight percent (8.0%).

Under the securities laws of some U.S. states, the Shares may be sold in such states only through registered or licensed brokers or
dealers. In addition, in some U.S. states the Shares may not be sold unless such shares have been registered or qualified for sale in such state
or an exemption from registration or qualification is available and is complied with.

There can be no assurance that any selling stockholder will sell any or all of the Shares registered pursuant to the shelf registration

statement, of which this prospectus forms a part.

Each  selling  stockholder  and  any  other  person  participating  in  such  distribution  will  be  subject  to  applicable  provisions  of  the
Exchange Act and the rules and regulations thereunder, including, without limitation, to the extent applicable, Regulation M of the Exchange
Act, which may limit the timing of purchases and sales of any of the Shares by the selling stockholder and any other participating person. To
the extent applicable, Regulation M may also restrict the ability of any person engaged in the distribution of the Shares to engage in market-
making activities with respect to the Shares. All of the foregoing may affect the marketability of the Shares and the ability of any person or
entity to engage in market-making activities with respect to the Shares.

We will pay all expenses of the registration of the Shares pursuant to the registration rights agreement, including, without limitation,
Securities and Exchange Commission filing fees and expenses of compliance with state securities or “blue sky” laws; provided, however, that
each selling stockholder will pay all underwriting discounts and selling commissions, if any and any related legal expenses incurred by it. We
will indemnify the selling stockholders against certain liabilities, including some liabilities under the Securities Act, in accordance with the
registration rights agreement, or the selling stockholders will be entitled to contribution. We may be indemnified by the selling stockholders
against  civil  liabilities,  including  liabilities  under  the  Securities  Act,  that  may  arise  from  any  written  information  furnished  to  us  by  the
selling  stockholders  specifically  for  use  in  this  prospectus,  in  accordance  with  the  related  registration  rights  agreements,  or  we  may  be
entitled to contribution.

The undersigned agrees to promptly notify the Company of any inaccuracies or changes in the information provided herein that may occur
subsequent  to  the  date  hereof  and  prior  to  the  effective  date  of  any  applicable  Resale  Registration  Statement.  All  notices  hereunder  and
pursuant  to  the  Agreement  shall  be  made  in  writing,  by  hand  delivery,  confirmed  or  facsimile  transmission,  first-class  mail  or  air  courier
guaranteeing  overnight  delivery  at  the  address  set  forth  below.  In  the  absence  of  any  such  notification,  the  Company  shall  be  entitled  to
continue to rely on the accuracy of the information in this Notice and Questionnaire.

By  signing  below,  the  undersigned  consents  to  the  disclosure  of  the  information  contained  herein  in  its  answers  to  Items  (1)  through  (7)
above and the inclusion of such information in the Resale Registration Statement and the Prospectus. The undersigned understands that such
information will be relied upon by the Company in connection with the preparation or amendment of any such Registration Statement and the

By  signing  below,  the  undersigned  acknowledges  that  it  understands  its  obligation  to  comply,  and  agrees  that  it  will  comply,  with  the
provisions  of  the  Exchange  Act  and  the  rules  and  regulations  thereunder,  particularly  Regulation  M  in  connection  with  any  offering  of

The  undersigned  hereby  acknowledges  and  is  advised  of  the  following  Question  239.10  of  the  Securities  Act  Rules  Compliance  and
Disclosure Interpretations regarding short selling:

“An Issuer filed a Form S-3 registration statement for a secondary offering of common stock which is not yet effective. One of the selling
stockholders wanted to do a short sale of common stock “against the box” and cover the short sale with registered shares after the effective
date. The issuer was advised that the short sale could not be made before the registration statement become effective, because the shares
underlying the short sale are deemed to be sold at the time such sale is made. There would, therefore, be a violation of Section 5 if the shares
were effectively sold prior to the effective date.”

By returning this Questionnaire, the undersigned will be deemed to be aware of the foregoing interpretation.

I confirm that, to the best of my knowledge and belief, the foregoing statements (including without limitation the answers to this
Questionnaire) are correct.

 
 
 
IN WITNESS WHEREOF the undersigned, by authority duly given, has caused this Questionnaire to be executed and delivered either in
person or by its duly authorized agent.
