Basis of Presentation

General

Except where the context otherwise requires, all references in this Annual Report on Form 20-F to the "Company", "Aeterna Zentaris", "we", "us", "our" or
similar words or phrases are to Aeterna Zentaris Inc. and its subsidiaries, taken together. In this Annual Report on Form 20-F, references to "$" and "U.S.$"
are to United States ("U.S.") dollars, references to "CAN$" are to Canadian dollars and references to "EUR" are to euros. Unless otherwise indicated, the
statistical and financial data contained in this Annual Report on Form 20-F are presented as at December 31, 2017.

All share, option and share purchase warrant as well as per share, option and share purchase warrant information presented in this Annual Report on Form 20-
F have been adjusted, including proportionate adjustments being made to each option and share purchase warrant exercise price, to reflect and to give effect
to  a  share  consolidation  (or  reverse  stock  split),  on  November  17,  2015,  of  our  issued  and  outstanding  common  shares  on  a  100-to-1  basis  (the  "Share
Consolidation").  The  Share  Consolidation  affected  all  shareholders,  optionholders  and  warrantholders  uniformly  and  thus  did  not  materially  affect  any
securityholder's percentage of ownership interest.

This Annual Report on Form 20-F also contains certain information regarding products or product candidates that may potentially compete with our products
and  product  candidates,  and  such  information  has  been  primarily  derived  from  information  made  publicly  available  by  the  companies  developing  such
potentially competing products and product candidates and has not been independently verified by Aeterna Zentaris Inc.

Forward-Looking Statements

This Annual Report on Form 20-F contains forward-looking statements made pursuant to the safe-harbor provision of the U.S. Securities Litigation Reform
Act  of  1995,  which  reflect  our  current  expectations  regarding  future  events.  Forward-looking  statements  may  include,  but  are  not  limited  to  statements
preceded  by,  followed  by,  or  that  include  the  words  "will,"  "expects,"  "believes,"  "intends,"  "would,"  "could,"  "may,"  "anticipates,"  and  similar  terms  that
relate  to  future  events,  performance,  or  our  results.  Forward-looking  statements  involve  known  risks  and  uncertainties,  including  those  discussed  in  this
Annual Report on Form 20-F, under the caption "Key Information - Risk Factors" filed with the relevant Canadian securities regulatory authorities in lieu of
an annual information form and with the U.S. Securities and Exchange Commission ("SEC"). Known and unknown risks and uncertainties could cause our
actual results to differ materially from those in forward-looking statements. Such risks and uncertainties include, among others, our now heavy dependence on
the success of Macrilen™ (macimorelin) and related out-licensing arrangements and the continued availability of funds and resources to successfully launch
the  product,  the  ability  of  Aeterna  Zentaris  to  enter  into  out-licensing,  development,  manufacturing  and  marketing  and  distribution  agreements  with  other
pharmaceutical  companies  and  keep  such  agreements  in  effect,  reliance  on  third  parties  for  the  manufacturing  and  commercialization  of  our  product
candidates, potential disputes with third parties, leading to delays in or termination of the manufacturing, development, out-licensing or commercialization of
our product candidates, or resulting in significant litigation or arbitration, and, more generally, uncertainties related to the regulatory process, the ability of the
Company to efficiently commercialize or out-license Macrilen™ (macimorelin), the degree of market acceptance of Macrilen™ (macimorelin), our ability to
obtain necessary approvals from the relevant regulatory authorities to enable us to use the desired brand names for our products, the impact of securities class
action  litigation,  the  litigation  involving  two  of  our  former  officers,  or  other  litigation,  on  our  cash  flow,  results  of  operations  and  financial  position;  any
evaluation of potential strategic alternatives to maximize potential future growth and stakeholder value may not result in any such alternative being pursued,
and  even  if  pursued,  may  not  result  in  the  anticipated  benefits,  our  ability  to  take  advantage  of  business  opportunities  in  the  pharmaceutical  industry,  our
ability to protect our intellectual property, the potential of liability arising from shareholder lawsuits and general changes in economic conditions. Investors
should  consult  the  Company's  quarterly  and  annual  filings  with  the  Canadian  and  U.S.  securities  commissions  for  additional  information  on  risks  and
uncertainties. Given these uncertainties and risk factors, readers are cautioned not to place undue reliance on these forward-looking statements. We disclaim
any obligation to update any such factors or to publicly announce any revisions to any of the forward-looking statements contained herein to reflect future
results, events or developments, unless required to do so by a governmental authority or applicable law.

Risk factors

An  investment  in  our  securities  involves  a  high  degree  of  risk.  You  should  carefully  consider  the  risks  described  below,  together  with  all  of  the  other
information  included  in  this  Annual  Report,  before  making  an  investment  decision.  If  any  of  the  following  risks  actually  occurs,  our  business,  prospects,
financial condition or results of operations could suffer. In that case, the trading price, if any, of our securities could decline, and you may lose all or part of
your investment.

Risks Relating to Us and Our Business

Investments in biopharmaceutical companies are generally considered to be speculative.

The prospects for companies operating in the biopharmaceutical industry are uncertain, given the very nature of the industry, and, accordingly, investments in
biopharmaceutical companies should be considered to be speculative assets.

We have a history of operating losses and we may never achieve or maintain operating profitability. In addition, if we are unsuccessful in generating new
revenue, increasing our revenue and/or raising additional funding, we may not be able to continue as a going concern.

We  have  incurred,  and  expect  to  continue  to  incur,  substantial  expenses  in  our  efforts  to  develop  and  market  products.  Consequently,  we  have  incurred
operating losses historically and in each of the last several years. As at December 31, 2017, we had an accumulated deficit of approximately $314 million.
Our operating losses have adversely impacted, and will continue to adversely impact, our working capital, total assets, operating cash flow and shareholders'
equity. We do not expect to reach operating profitability in the immediate future, and our operating expenses are likely to continue to represent a significant
component  of  our  overall  cost  profile  as  we  focus  on  the  development  and  commercialization  of  Macrilen™  (macimorelin),  including  out-licensing
arrangements,  pursuing  in-licensing  opportunities  or  acquiring  marketed  products.  In  developing,  acquiring,  out-licensing  or  in-licensing  Macrilen™
(macimorelin) or other commercial products, we could incur additional operating losses for at least the next several years. If we do not ultimately generate
sufficient revenue from a commercialized product and achieve or maintain operating profitability, an investment in our Common Shares or other securities
could result in a significant or total loss.

Our ability to continue as a going concern is dependent on the successful execution of our business plan, which will require an increase in revenue and/or
additional funding to be provided by potential investors and/or non-traditional sources of financing. Although  we  did  not  have,  as  at  December 31, 2017,
sufficient liquidity and financial resources to fund planned expenditures and

3

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
other working capital needs, because of the $24 million upfront payment received on January 17, 2018 for the licensing of Macrilen™ (macimorelin) in the
United States and Canada, as of the issuance of this Annual Report on Form 20-F we expect to have sufficient resources for the next 12 months.

Additional funding may be in the form of debt or equity or a hybrid instrument depending on our needs, the demands of investors and market conditions.
Depending on the prevailing global economic and credit market conditions, we may not be able to raise additional cash through these traditional sources of
financing. Although we may also pursue non-traditional sources of financing with third parties, the global equity and credit markets may adversely affect the
ability of potential third parties to pursue such transactions with us. Accordingly, as a result of the foregoing, we continue to review traditional sources of
financing, such as private and public debt or various equity financing alternatives, as well as other alternatives to enhance shareholder value, including, but
not limited to, non-traditional sources of financing, such as strategic alliances with third parties, the sale of assets or licensing of our technology or intellectual
property, a combination of operating and related initiatives or a substantial reorganization of our business.

There can be no assurance that we will achieve profitability or positive cash flows or be able to obtain additional funding or that, if obtained, the additional
funding will be sufficient, or whether any other initiatives will be successful such that we may continue as a going concern. There could also be material
uncertainties related to certain adverse conditions and events that could impact our ability to remain a going concern. If the going concern assumptions were
deemed  no  longer  appropriate  for  our  consolidated  financial  statements,  adjustments  to  the  carrying  value  of  assets  and  liabilities,  reported  expenses  and
consolidated statement of financial position classifications would be necessary. Such adjustments could be material.

Our revenues and expenses may fluctuate significantly, and any failure to meet financial expectations may disappoint securities analysts or investors and
result in a decline in the price or the value of our Common Shares or other securities.

We have a history of operating losses. Our revenues and expenses have fluctuated in the past and may continue to do so in the future. These fluctuations could
cause our share price or the value of our other securities to decline. Some of the factors that could cause our revenues and expenses to fluctuate include but
are not limited to:

•

•

•

•

•

•

•

•

•

the  inability  to  complete  product  development  in  a  timely  manner  that  results  in  a  failure  or  delay  in  receiving  the  required  regulatory  approvals  to
commercialize a product;

not obtaining necessary regulatory approvals from the U.S. Food and Drug Administration ("FDA"), European Medicines Agency ("EMA") and other
agencies that may delay or prevent us from bringing a product to market, which may affect the price of our securities;

the timing of regulatory submissions and approvals;

the timing and willingness of any current or future collaborators to invest the resources necessary to commercialize Macrilen™ (macimorelin) or other
products;

the nature and timing of licensing fee revenues;

the outcome of litigation, including the securities class action litigation pending against us that is described elsewhere in this Annual Report on Form 20-
F;

foreign currency fluctuations;

the timing of the achievement and the receipt of milestone payments from current or future collaborators; and

failure to enter into new or the expiration or termination of current agreements with collaborators.

Due to fluctuations in our revenues and expenses, we believe that period-to-period comparisons of our results of operations are not necessarily indicative of
our future performance. It is possible that in some future periods, our revenues and expenses will be above or below the expectations of securities analysts or
investors. In this case, the price of our Common Shares and/or the value of our other securities could fluctuate significantly or decline.

If we decide to pursue new clinical trial programs for new products in the future and are unable to successfully complete those clinical trial programs, or
if such clinical trials take longer to complete than we project, our ability to execute any related business strategy will be adversely affected.

We are currently not conducting any clinical trials but we may decide to do so in the future. If we experience delays in identifying and contracting with sites
and/or in-patient enrollment in our future clinical trial programs, we may incur additional costs and delays in our development programs, and may not be able
to complete our clinical trials on a cost-effective or timely basis. In

4

addition, conducting multi-national studies adds another level of complexity and risk as we are subject to events affecting countries other than the United
States and Canada. Moreover, negative or inconclusive results from the clinical trials we conduct or adverse medical events could cause us to have to repeat
or terminate the clinical trials. Accordingly, we may not be able to complete the clinical trials within an acceptable time-frame, if at all. If we or our contract
resource organization (a "CRO") have difficulty enrolling a sufficient number of patients to conduct our clinical trials as planned, we may need to delay or
terminate ongoing clinical trials.

Clinical trials are subject to continuing oversight by governmental regulatory authorities and institutional review boards and must, among other requirements:

• meet the requirements of these authorities from multiple countries and jurisdictions and their related statutes, regulations, and guidances;

• meet the requirements for informed consent;

• meet the requirements for institutional review boards; and

• meet the requirements for good clinical practices

If we are unable to commercialize or out-license Macrilen™ (macimorelin), or if we experience significant delays in doing so, our business would be
materially harmed and the future and viability of our Company could be imperiled.

Our principal focus is on the licensing and development of Macrilen™ (macimorelin). The commercial success of Macrilen™ (macimorelin) will depend on
several factors, including the following:

•

•

•

•

•

•

receipt of approvals from the EMA, and similar foreign regulatory authorities;

successfully contracting with qualified third party manufacturers to manufacture Macrilen™ (macimorelin);

developing appropriate distribution and marketing infrastructure and arrangements for our product;

launching and growing commercial sales of the product;

out-licensing Macrilen™ (macimorelin) to third parties; and

acceptance of the product in the medical community, among patients and with third party payers.

If we are unable to successfully achieve any of these factors, our business, financial condition and results of operations may be materially adversely affected.

We  are  currently  dependent  on  certain  strategic  relationships  with  third  parties  for  the  development,  manufacturing  and  licensing  of  Macrilen™
(macimorelin)  and  we  may  enter  into  future  collaborations  for  the  development,  manufacturing  and  licensing  of  Macrilen™  (macimorelin)  or  future
products.

We are currently dependent on certain strategic relationships with third parties for the development, manufacturing and licensing of Macrilen™ (macimorelin)
and may enter into future collaborations for the development and licensing of Macrilen™ (macimorelin) or future products. Our arrangements with these third
parties may not provide us with the benefits we expect and may expose us to a number of risks.

We  are  dependent  on,  and  rely  upon,  third  parties  to  perform  various  functions  related  to  our  business,  including,  but  not  limited  to,  development,
manufacturing and licensing of Macrilen™ (macimorelin). Our reliance on these relationships poses a number of risks. We may not realize the contemplated
benefits of such agreements nor can we be certain that any of these parties will fulfill their obligations in a manner which maximizes our revenue. These
arrangements may also require us to transfer certain material rights to third parties. These agreements create certain additional risks. The occurrence of any of
the following or other events may delay or impair commercialization of our products:

•

not all of the third parties are contractually prohibited from developing or commercializing, either alone or with others, products that are similar to or
competitive with our product candidates and, with respect to our contracts that do contain such contractual prohibitions or restrictions, prohibitions
or  restrictions  do  not  always  apply  to  the  affiliates  of  the  third  parties  and  they  may  elect  to  pursue  the  development  of  any  additional  product
candidates  and  pursue  technologies  or  products  either  on  their  own  or  in  collaboration  with  other  parties,  including  our  competitors,  whose
technologies  or  products  may  be  competitive  with  ours;  the  third  parties  may  under-fund  or  fail  to  commit  sufficient  resources  to  marketing,
distribution or other development of our products;

5

•

•

•

•

•

•

the third parties may cease to conduct business for financial or other reasons;

we may not be able to renew such agreements;

the  third  parties  may  not  properly  maintain  or  defend  certain  intellectual  property  rights  that  may  be  important  to  the  commercialization  of  our
products;

the third parties may encounter conflicts of interest, changes in business strategy or other issues which could adversely affect their willingness or
ability to fulfill their obligations to us (for example, pharmaceutical companies historically have re-evaluated their priorities following mergers and
consolidations, which have been common in recent years in this industry);

delays in, or failures to achieve, scale-up to commercial quantities, or changes to current raw material suppliers or product manufacturers (whether
the change is attributable to us or the supplier or manufacturer) could delay clinical studies, regulatory submissions and commercialization of our
products; and

disputes  may  arise  between  us  and  the  third  parties  that  could  result  in  the  delay  or  termination  of  the  development,  manufacturing  or
commercialization of our product candidates, resulting in litigation or arbitration that could be time-consuming and expensive, or causing the third
parties to act in their own self-interest and not in our interest or those of our shareholders or other stakeholders.

In addition, the third parties can terminate our agreements with them for a number of reasons based on the terms of the individual agreements that we have
entered  into  with  them.  If  one  or  more  of  these  agreements  were  to  be  terminated,  we  would  be  required  to  devote  additional  resources  to  developing,
manufacturing and commercializing our products, seek a new third party with which to contract or abandon the product candidate, which would likely cause a
drop in the price of our Common Shares and/or a decline in the value of our other securities.

We  have  incurred,  and  expect  to  continue  to  incur,  substantial  expenses,  and  we  have  made,  and  expect  to  continue  to  make,  substantial  financial
commitments to establish a commercial operation. There can be no assurance how quickly, if ever, we will realize a profit from our commercial operation.

Our  business  strategy  is  to  become  a  specialty  biopharmaceutical  company  with  commercial  operations  to  market  and  sell  products  that  we  may  either
develop  internally,  acquire  or  in‑license.  Currently,  we  are  focused  on  the  commercialization  of  Macrilen™  (macimorelin),  including  out-licensing
arrangements and pursuing in-licensing opportunities. We have to date incurred, and expect to continue to incur, substantial expenses (including restructuring
costs  associated  with  the  2017  German  Restructuring  described  in  Item  5),  and  we  have  made,  and  expect  to  continue  to  make,  substantial  financial
commitments  to  build  and  maintain  commercial  operations.  Establishing  a  commercial  operation  is  expensive  and  time-consuming,  and  there  can  be  no
assurance  how  quickly,  if  ever,  we  will  realize  a  profit  from  our  commercial  operations.  Factors  that  may  inhibit  our  efforts  to  realize  a  profit  from  our
commercial operations include:

•

•

•

•

•

our ability to develop appropriate distribution and marketing infrastructure and arrangements for our product;

the lack of complementary products, which may put us at a competitive disadvantage relative to companies with more extensive product lines; 

enforcement  action  by  the  FDA,  EMA  or  other  regulatory  authorities,  or  lawsuit  by  a  competitor,  resulting  from  the  Company  or  any  of  its  vendors,
licenses, agents, or sales representatives marketing a product off-label;

compliance issues with healthcare fraud and abuse laws and regulations from multiple countries and jurisdictions; and

unforeseen costs and expenses associated with creating an independent sales and marketing organization.

Our financial viability depends, in part, on our ability to acquire, in-license or otherwise obtain the right to sell other products. If we are unable to do so,
our business, financial condition and results of operations may be materially adversely affected.

In  connection  with  our  strategy  to  further  transform  the  Company  into  a  commercially  operating  specialty  biopharmaceutical  organization,  we  through
Aeterna  Zentaris  GmbH  ("AEZS  Germany"),  entered  into  a  license  and  assignment  agreement  on  January  16,  2018,  with  Strongbridge  Ireland  Limited
("Strongbridge") to carry out development, manufacturing, registration and commercialization of Macrilen™ (macimorelin) in the United States and Canada
(the "Strongbridge License Agreement").

We  may  enter  into  additional  commercial  agreements  with  third  parties,  in  efforts  to  establish  and  expand  our  commercial  revenue  base.  These  business
activities entail numerous operational and financial risks, including:

6

•

•

•

•

•

•

the difficulty or inability to secure financing to acquire or in-license products;

the incurrence of substantial debt or dilutive issuances of securities to pay for the acquisition or in-licensing of new products;

the disruption of our business and diversion of our management's time and attention;

higher than expected development, acquisition or in-license and integration costs;

exposure to unknown liabilities; and

the difficulty in locating products that are in our targeted therapeutic areas and that are compatible with other products in our portfolio.

We can provide no assurance that we will be able to identify potential product candidates or strategic commercial partners or, if we identify such product
candidates or partners, that any related commercial arrangements will be consummated on terms that are favorable to us. We cannot provide any assurance
that the Strongbridge License Agreement will be successful, nor can we provide assurance that any future strategic commercial arrangements, or initiatives or
activities  resulting  therefrom,  will  be  successful.  To  the  extent  that  any  related  investments  in  such  arrangements,  including  the  Strongbridge  License
Agreement, do not yield the expected benefits, our business, financial condition and results of operations may be materially adversely affected.

We have limited resources to identify and execute the procurement of additional products and to integrate them into our commercial operations. The failure to
successfully integrate the personnel and operations of businesses that we may acquire or of products that we may in-license in the future with our existing
operations, business and products could have a material adverse effect on our operations and results. We compete with larger pharmaceutical companies and
other competitors in our efforts to acquire, in-license, and/or obtain the right to market and/or detail new products. Our competitors likely will have access to
greater financial resources than us and may have greater expertise in identifying and evaluating new opportunities. Moreover, we may devote resources to
potential, in-licensing opportunities that are never completed, or we may fail to realize the anticipated benefits of such efforts.

We may require significant additional financing, and we may not have access to sufficient capital.

We  may  require  significant  additional  capital  to  fund  our  commercial  operations  and  may  require  additional  capital  to  pursue  planned  clinical  trials  and
regulatory approvals, as well as further R&D and marketing efforts for our product candidates and potential products. Although we have capital from the
Strongbridge License Agreement, we do not anticipate generating significant revenues from operations in the near future other than from the Strongbridge
License Agreement, and we currently have no committed sources of capital.

We may attempt to raise additional funds through public or private financings, collaborations with other pharmaceutical companies or from other sources,
including, without limitation, through at-the-market offerings and issuances of Common Shares. Additional funding may not be available on terms that are
acceptable  to  us.  If  adequate  funding  is  not  available  to  us  on  reasonable  terms,  we  may  need  to  delay,  reduce  or  eliminate  one  or  more  of  our  product
development programs or obtain funds on terms less favorable than we would otherwise accept. To the extent that additional capital is raised through the sale
of equity securities or securities convertible into or exchangeable or exercisable for equity securities, the issuance of those securities would result in dilution
to our shareholders. Moreover, the incurrence of debt financing or the issuance of dividend-paying preferred shares, could result in a substantial portion of our
future  operating  cash  flow,  if  any,  being  dedicated  to  the  payment  of  principal  and  interest  on  such  indebtedness  or  the  payment  of  dividends  on  such
preferred  shares  and  could  impose  restrictions  on  our  operations  and  on  our  ability  to  make  certain  expenditures  and/or  to  incur  additional  indebtedness,
which could render us more vulnerable to competitive pressures and economic downturns.

Our future capital requirements are substantial and may increase beyond our current expectations depending on many factors, including:

•

•

•

•

•

the duration of changes to and results of our clinical trials for any future products going forward;

unexpected delays or developments in seeking regulatory approvals;

the time and cost involved in preparing, filing, prosecuting, maintaining and enforcing patent claims;

unexpected developments encountered in implementing our business development and commercialization strategies;

the potential addition of commercialized products to our portfolio;

7

•

•

the outcome of litigation, including the securities class action litigation pending against us that is described elsewhere in this Annual Report on Form 20-
F; and

further arrangements, if any, with collaborators.

In addition, global economic and market conditions as well as future developments in the credit and capital markets may make it even more difficult for us to
raise additional financing in the future.

We  are  and  will  be  subject  to  stringent  ongoing  government  regulation  for  our  products  and  our  product  candidates,  even  if  we  obtain  regulatory
approvals for the latter.

The manufacture, marketing and sale of Macrilen™ (macimorelin) and future products are and will be subject to strict and ongoing regulation, even with
marketing  approval  by  the  FDA  for  Macrilen™  (macimorelin),  and  even  if  the  EMA  and  other  regulatory  authorities  approve  our  future  products.
Compliance with such regulation will be expensive and consume substantial financial and management resources. For example, an approval for a product
may be conditioned on our agreement to conduct costly post-marketing follow-up studies to monitor the safety or efficacy of the products. In addition, as
clinical experience with a drug expands after approval because the drug is used by a greater number and more diverse group of patients than during clinical
trials, side effects or other problems may be observed after approval that were not observed or anticipated during pre-approval clinical trials. In such a case, a
regulatory authority could restrict the indications for which the product may be sold or revoke the product's regulatory approval. Even though the New Drug
Application ("NDA") regarding Macrilen™ (macimorelin) is approved by the FDA, the FDA may still require post-market clinical studies and there is a risk
that the results of the studies may not meet FDA's requirements.

We and our contract manufacturers will be required to comply with applicable Current Good Manufacturing Practice regulations for the manufacture of our
current  or  future  products  and  other  regulations.  These  regulations  include  requirements  relating  to  quality  assurance,  as  well  as  the  corresponding
maintenance of rigorous records and documentation. Manufacturing facilities must be approved before we can use them in the commercial manufacturing of a
product and are subject to subsequent periodic inspection by regulatory authorities. In addition, material changes in the methods of manufacturing or changes
in the suppliers of raw materials are subject to further regulatory review and approval.

If  we,  or  if  any  future  marketing  collaborators  or  contract  manufacturers,  fail  to  comply  with  applicable  regulatory  requirements,  we  may  be  subject  to
sanctions including fines, product recalls or seizures and related publicity requirements, injunctions, total or partial suspension of production, civil penalties,
suspension  or  withdrawals  of  previously  granted  regulatory  approvals,  warning  or  untitled  letters,  refusal  to  approve  pending  applications  for  marketing
approval of new products or of supplements to approved applications, complete withdrawal of a marketing application, exclusion from government healthcare
programs,  import  or  export  bans  or  restrictions,  and/or  criminal  prosecution  and  penalties.  Any  of  these  penalties  could  delay  or  prevent  the  promotion,
marketing or sale of a product.

During the drug development process, regulatory agencies will typically ask questions of drug sponsors. While we endeavor to answer all such questions in a
timely fashion, some questions may not be answered in time to prevent the delay of acceptance of an NDA or the rejection of an NDA. Additionally, if the
Company plans to market products in other countries, the Company may fail to obtain necessary regulatory approvals in those countries. We are not opining
on the success of the Company's products in the United States or in any other countries.

Even  with  marketing  approval  for  Macrilen™  (macimorelin),  such  product  approval  could  be  subject  to  restrictions  or  withdrawals.  Regulatory
requirements are subject to change.

On December 20, 2017, the FDA granted marketing approval for Macrilen™ (macimorelin) to be used in the diagnosis of patients with adult growth hormone
deficiency ("AGHD"). Regulatory authorities generally approve products for specified indications. If an approval is for a limited indication, this limitation
reduces  the  size  of  the  potential  market  for  that  product.  Product  approvals,  once  granted,  are  subject  to  continual  review  and  periodic  inspections  by
regulatory  authorities.  Our  operations  and  practices  are  subject  to  regulation  and  scrutiny  by  the  U.S.  government,  as  well  as  governments  of  any  other
countries  in  which  we  do  business  or  conduct  activities.  Later  discovery  of  previously  unknown  problems  or  safety  issues  and/or  failure  to  comply  with
domestic  or  foreign  laws,  knowingly  or  unknowingly,  can  result  in  various  adverse  consequences,  including,  among  other  things,  a  possible  delay  in  the
approval or refusal to approve a product, warning or untitled letters, fines, injunctions, civil penalties, recalls or seizures of products and related publicity
requirements,  total  or  partial  suspension  of  production,  import  or  export  bans  or  restrictions,  refusal  of  the  government  to  renew  marketing  applications,
complete withdrawal of a marketing application, criminal prosecution and penalties, suspension or withdrawals of previously granted regulatory approvals,
withdrawal of an approved product from the market and/or exclusion from government healthcare programs. Such regulatory enforcement could have a direct
and negative impact on the product for which approval is granted, but also could have a negative impact on the approval of any pending applications for
marketing approval of new drugs or supplements to approved applications.

8

Because we operate in a highly regulated industry, regulatory authorities could take enforcement action against us in connection with our or our licensees' or
collaborators', business and marketing activities for various reasons.

From  time  to  time,  new  legislation  is  passed  into  law  that  could  significantly  change  the  statutory  provisions  governing  the  approval,  manufacturing,  and
marketing of products regulated by the FDA, EMA and other health authorities. Additionally, regulations and guidance are often revised or reinterpreted by
health  agencies  in  ways  that  may  significantly  affect  our  business  Macrilen™  (macimorelin)  and  our  future  products.  It  is  impossible  to  predict  whether
further  legislative  changes  will  be  enacted,  or  whether  regulations,  guidance,  or  interpretations  will  change,  and  what  the  impact  of  such  changes,  if  any,
may be.

Healthcare reform measures could hinder or prevent the commercial success of a product and adversely affect our business.

The business prospects and financial condition of pharmaceutical and biotechnology companies are affected by the efforts of governmental and third-party
payers to contain or reduce the costs of healthcare. The U.S. government and other governments have shown significant interest in pursuing healthcare reform
and reducing healthcare costs. Any government-adopted reform measures could cause significant pressure on the pricing of healthcare products and services,
including Macrilen™ (macimorelin) and future products, both in the United States and internationally, as well as the amount of reimbursement available from
governmental agencies and other third-party payers. If reimbursement for Macrilen™ (macimorelin) or future products is substantially less than we expect,
our revenue prospects could be materially and adversely impacted.

In the United States and in other jurisdictions there have been, and we expect that there will continue to be, a number of legislative and regulatory proposals
aimed at changing the healthcare system, such as proposals relating to the pricing of healthcare products and services in the United States or internationally,
the reimportation of drugs into the U.S. from other countries (where they are then sold at a lower price), and the amount of reimbursement available from
governmental agencies or other third party payers. Furthermore, the pricing of pharmaceutical products, in general, and specialty drugs, in particular, has been
a topic of concern in the U.S. Congress, where hearings on the topic have been held, and has been a topic of speeches given by political figures, including
President Donald Trump. Additionally, in the United States, states have also passed legislation and proposed bills that are aimed at drug pricing transparency,
which will likely impact drug pricing. There can be no assurance as to how this scrutiny on pricing of pharmaceutical products will impact future pricing of
Macrilen™ (macimorelin), our future products, or orphan drugs or pharmaceutical products generally.

The Patient Protection and Affordable Care Act and the Healthcare and Education Affordability Reconciliation Act of 2010 (collectively, the "ACA") has had
far-reaching  consequences  for  most  healthcare  companies,  including  specialty  biopharmaceutical  companies  like  us.  The  future  of  the  ACA  is,  however,
uncertain. Since January 2017, the U.S. Congress has proposed various bills to revise the ACA. Additionally, President Donald Trump has suggested similar
action and enacted Executive Orders to curtail the ACA and its impacts on healthcare in the United States. We cannot predict the ultimate content, timing or
effect of any healthcare reform legislation or the impact of potential legislation, regulation, and orders or their impact on us.

In addition, the Food and Drug Administration Amendments Act of 2007 gives the FDA enhanced post-market authority, including the authority to require
post-marketing studies and clinical trials, labeling changes based on new safety information, and compliance with risk evaluations and mitigation strategies
approved by the FDA. The FDA's exercise of this authority may result in delays or increased costs during the period of product development, clinical trials
and  regulatory  review  and  approval,  which  may  also  increase  costs  related  to  complying  with  new  post-approval  regulatory  requirements,  and  increase
potential FDA restrictions on the sale or distribution of approved products.

If we market products or interact with health care practitioners in a manner that violates healthcare fraud and abuse laws, we may be subject to civil or
criminal penalties, including exclusion from participation in government healthcare programs.

As a pharmaceutical company, even though we do not provide healthcare services or receive payments directly from or bill directly to Medicare, Medicaid or
other third-party payers for our current or future products, certain federal and state healthcare laws and regulations pertaining to fraud and abuse are and will
be applicable to our business. We are subject to healthcare fraud and abuse regulation by both the federal government and the states in which we conduct
our business.

The laws that may affect our ability to operate include the federal healthcare program anti-kickback statute, which prohibits, among other things, knowingly
and willfully offering, paying, soliciting, or receiving remuneration to induce, or in return for, the purchase, lease, order, or arrangement for the purchase,
lease or order of any healthcare item or service reimbursable under Medicare, Medicaid or other federally financed healthcare programs. This statute applies
to  arrangements  between  pharmaceutical  manufacturers  and  prescribers,  purchasers  and  formulary  managers.  Although  there  are  a  number  of  statutory
exceptions and regulatory safe harbors protecting certain common activities, the exceptions and safe harbors are drawn narrowly, and practices that involve
remuneration intended to induce prescribing, purchases or recommendations may be subject to scrutiny if they do not qualify for an exception or safe harbor.

9

Federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government, or
knowingly making, or causing to be made, a false statement to get a false claim paid. Pharmaceutical companies have been prosecuted under these laws for a
variety of alleged promotional and marketing activities, such as providing free product to customers with the expectation that the customers would bill federal
programs for the product; reporting to pricing services inflated average wholesale prices that were then used by federal programs to set reimbursement rates;
engaging in off-label promotion that caused claims to be submitted to Medicaid for non-covered off-label uses; and submitting inflated best price information
to the Medicaid Drug Rebate Program.

The Health Insurance Portability and Accountability Act of 1996 also created prohibitions against healthcare fraud and false statements relating to healthcare
matters.  The  healthcare  fraud  statute  prohibits  knowingly  and  willfully  executing  a  scheme  to  defraud  any  healthcare  benefit  program,  including  private
payers. The false statements statute prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false,
fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services.

In addition, there has been a recent trend of increased federal and state regulation of payments made to physicians. The ACA, through the Physician Payment
Sunshine Act, imposed new requirements on manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare,
Medicaid or the Children's Health Insurance Program (with certain exceptions) to report annually to the Centers for Medicare and Medicaid Services ("CMS")
information  related  to  payments  or  other  "transfers  of  value"  made  to  physicians  (defined  to  include  doctors,  dentists,  optometrists,  podiatrists  and
chiropractors) and teaching hospitals, and applicable manufacturers and group purchasing organizations to report annually to CMS ownership and investment
interests held by physicians (as defined above) and their immediate family members and payments or other "transfers of value" to such physician owners and
their immediate family members. Manufacturers are required to report such data to the government by the 90th calendar day of each year.

The majority of states also have statutes or regulations similar to these federal laws, which apply to items and services reimbursed under Medicaid and other
state  programs,  or,  in  several  states,  apply  regardless  of  the  payer.  In  addition,  some  states  have  laws  that  require  pharmaceutical  companies  to  adopt
comprehensive  compliance  programs.  For  example,  under  California  law,  pharmaceutical  companies  must  comply  with  both  the  April  2003  Office  of
Inspector General Compliance Program Guidance for Pharmaceutical Manufacturers and the PhRMA Code on Interactions with Healthcare Professionals, as
amended. Certain states also mandate the tracking and reporting of gifts, compensation, and other remuneration paid by us to physicians and other healthcare
providers.

Although compliance programs can mitigate the risk of investigation and prosecution for violations of these laws, the risks cannot be entirely eliminated. Any
action  against  us  for  violation  of  these  laws,  even  if  we  successfully  defend  against  it,  could  cause  us  to  incur  significant  legal  expenses  and  divert  our
management's  attention  from  the  operation  of  our  business.  Moreover,  achieving  and  sustaining  compliance  with  applicable  federal  and  state  laws  may
prove costly.

Because of the breadth of these laws and the narrowness of the safe harbors, it is possible that some of our business activities could be subject to challenge
under one or more of such laws. The ACA also made several important changes to the federal anti-kickback statute, false claims laws, and healthcare fraud
statute  by  weakening  the  intent  requirement  under  the  anti-kickback  and  healthcare  fraud  statutes  that  may  make  it  easier  for  the  government  or
whistleblowers to charge such fraud and abuse violations. A person or entity no longer needs to have actual knowledge of this statute or specific intent to
violate it. In addition, the ACA provides that the government may assert that a claim including items or services resulting from a violation of the federal anti-
kickback statute constitutes a false or fraudulent claim for purposes of the false claims statutes. In addition, the ACA increases penalties for fraud and abuse
violations. If our past, present or future operations are found to be in violation of any of the laws described above or other similar governmental regulations to
which we are subject, we may be subject to significant civil, criminal and administrative penalties, damages, fines, imprisonment, exclusion from government
funded healthcare programs, such as Medicare and Medicaid, and the curtailment or restructuring of our operations, any of which could adversely affect our
ability to operate our business and negatively impact our financial results.

If our products do not gain market acceptance, we may be unable to generate significant revenues.

Even though Macrilen™ (macimorelin) is approved for commercialization in the U.S., it may not be successful in the marketplace. Market acceptance of
Macrilen™ (macimorelin) or any of our products will depend on a number of factors, including, but not limited to:

•

•

•

demonstration of clinical efficacy and safety;

the prevalence and severity of any adverse side effects;

limitations or warnings contained in the product's approved labeling;

10

•

•

•

•

availability of alternative treatments for the indications we target;

the advantages and disadvantages of Macrilen™ (macimorelin) or future products relative to current or alternative treatments;

the availability of acceptable pricing and adequate third-party reimbursement; and

the effectiveness of marketing and distribution methods for the products.

If Macrilen™ (macimorelin) or our future products do not gain market acceptance among physicians, patients, healthcare payers and others in the medical
community, who may not accept or utilize our products, our ability to generate significant revenues from these products would be limited, and our financial
condition  could  be  materially  adversely  affected.  In  addition,  if  we  fail  to  further  penetrate  our  core  markets  and  existing  geographic  markets  or  to
successfully expand our business into new markets, the growth in sales of our current or future products, along with our operating results, could be negatively
impacted.

Our ability to further penetrate our core markets and existing geographic markets in which we compete or to successfully expand our business into additional
countries  in  Europe,  Asia  or  elsewhere  is  subject  to  numerous  factors,  many  of  which  are  beyond  our  control.  Macrilen™  (macimorelin)  or  our  future
products,  if  successfully  developed,  may  compete  with  a  number  of  drugs,  therapies,  products  and  tests  currently  manufactured  and  marketed  by  major
pharmaceutical and other biotechnology companies. Macrilen™ (macimorelin) or our future products may also compete with new products currently under
development  by  others  or  with  products  which  may  be  less  expensive  than  our  current  or  future  products.  There  can  be  no  assurance  that  our  efforts  to
increase market penetration in our core markets and existing geographic markets will be successful. Our failure to do so could have an adverse effect on our
operating results and would likely cause a drop in the price of our Common Shares and/or a decline in the value of our other securities.

We may expend our limited resources to pursue a particular product or indication and fail to capitalize on other products or indications for which there
may be a greater likelihood of success.

Because we have limited financial and managerial resources, we are currently focusing our efforts on Macrilen™ (macimorelin), and we are doing so for
specific  indications.  As  a  result,  we  may  forego  or  delay  pursuit  of  opportunities  with  products  or  for  other  indications  for  which  there  may  be  a  greater
likelihood  of  success  or  may  prove  to  have  greater  commercial  potential.  Research  programs  to  identify  new  product  candidates  or  pursue  alternative
indications  for  Macrilen™  (macimorelin)  require  substantial  technical,  financial  and  human  resources.  These  activities  may  initially  show  promise  in
identifying potential product candidates or indications, yet fail to yield product candidates or indications for further clinical development.

We may not achieve our projected development goals in the time-frames we announce and expect.

We may set goals and make public statements regarding the timing of the accomplishment of objectives material to our success, such as the commencement,
enrollment and anticipated completion of clinical trials, anticipated regulatory submission and approval dates and time of product launch. The actual timing of
these events can vary dramatically due to factors such as delays or failures in any clinical trials, the uncertainties inherent in the regulatory approval process
and delays in achieving manufacturing or marketing arrangements sufficient to commercialize Macrilen™ (macimorelin) or future products. There can be no
assurance  that  we  will  make  regulatory  submissions  or  receive  regulatory  approvals  as  planned  or  that  Strongbridge  will  be  able  to  adhere  to  its  current
schedule  for  the  launch  of  Macrilen™  (macimorelin)  or  for  any  future  products  we  might  acquire  or  license.  If  we  fail  to  achieve  one  or  more  of  these
milestones as planned, the price of our Common Shares and/or the value of our other securities would likely decline.

If we fail to obtain acceptable prices or adequate reimbursement for Macrilen™ (macimorelin) or future products, our ability to generate revenues will
be diminished.

Our  ability  or  that  of  our  licensee(s)  to  successfully  commercialize  Macrilen™  (macimorelin)  or  future  products  will  depend  significantly  on  our  or  their
ability to obtain acceptable prices and the availability of reimbursement to the patient from third-party payers, such as governmental and private insurance
plans. These third-party payers frequently require companies to provide predetermined discounts from list prices, and they are increasingly challenging the
prices charged for pharmaceuticals and other medical products. Macrilen™ (macimorelin) or our future products may not be considered cost-effective, and
reimbursement to the patient may not be available or sufficient to allow us or our licensee(s) to sell our products on a competitive basis. It may not be possible
to negotiate favorable reimbursement rates for Macrilen™ (macimorelin) or future products. Adverse pricing and reimbursement conditions would also likely
diminish our ability to induce third parties to in-license Macrilen™ (macimorelin) or our future products.

In  addition,  the  continuing  efforts  of  third-party  payers  to  contain  or  reduce  the  costs  of  healthcare  through  various  means  may  limit  our  commercial
opportunity and reduce any associated revenue and profits. We expect that proposals to implement similar government controls will continue. The pricing of
pharmaceutical products, in general, and specialty drugs, in particular, has been

11

a topic of concern in the U.S. Congress, where hearings on the topic have been held, and has been a topic of speeches given by political figures, including
President Donald Trump. Specifically, there have been several recent U.S. Congressional inquiries and proposed bills designed to, among other things, bring
more  transparency  to  drug  pricing,  review  the  relationship  between  pricing  and  manufacturer  patient  programs,  and  reform  government  program
reimbursement methodologies for drugs. Additionally, there is drug pricing reform taking place at the state level in the United States, in the form of laws and
bills,  that  will  impact  how  pharmaceutical  companies  can  market  and  sell  drug  products  and  at  what  price.  Further,  third-party  payers  are  increasingly
challenging the price, examining the medical necessity and reviewing the cost-effectiveness of medical drug products and medical services, in addition to
questioning their safety and efficacy. There can be no assurance as to how this scrutiny on pricing of pharmaceutical products will impact future pricing of a
product or orphan drugs or pharmaceutical products generally. In addition, increasing emphasis on managed care will continue to put pressure on the pricing
of pharmaceutical and biopharmaceutical products. Cost control initiatives could decrease the price that we or any current or potential collaborators could
receive a product and could adversely affect our profitability. In addition, in the United States, Canada and many other countries, pricing and/or profitability
of some or all prescription pharmaceuticals and biopharmaceuticals are subject to government control.

If we or our licensee(s) fail to obtain acceptable prices or an adequate level of reimbursement for Macrilen™ (macimorelin) or future products, the sales of
these products would be adversely affected or there may be no commercially viable market for these products.

Competition  in  our  targeted  markets  is  intense,  and  development  by  other  companies  could  render  Macrilen™  (macimorelin)  or  future  products  or
technologies non-competitive.

The biopharmaceutical field is highly competitive. New products developed by other companies in the industry could render Macrilen™ (macimorelin) or
future  products  uncompetitive.  Competitors  are  developing  and  testing  products  and  technologies  that  would  compete  with  Macrilen™  (macimorelin)  or
products  that  we  could  develop,  acquire  or  license.  Some  of  these  products  may  be  more  effective  or  have  an  entirely  different  approach  or  means  of
accomplishing  the  desired  effect  than  Macrilen™  (macimorelin)  or  future  products.  We  expect  competition  from  pharmaceutical  and  biopharmaceutical
companies and academic research institutions to continue to increase over time. Many of our competitors and potential competitors have substantially greater
product development capabilities and financial, scientific, marketing and human resources than we do. Our competitors may succeed in developing products
earlier and in obtaining regulatory approvals and patent protection for such products more rapidly than we can or at a lower price.

We may not obtain adequate protection for our products through our intellectual property.

We rely heavily on our proprietary information in developing and manufacturing our product candidates. Our success depends, in large part, on our ability to
protect our competitive position through patents, trade secrets, trademarks and other intellectual property rights. The patent positions of pharmaceutical and
biopharmaceutical firms, including us, are uncertain and involve complex questions of law and fact for which important legal issues remain unresolved. We
have filed and are pursuing applications for patents and trademarks in many countries. Pending patent applications may not result in the issuance of patents
and we may not be able to obtain additional issued patents relating to our technology or products.

The laws of some countries do not protect intellectual property rights to the same extent as the laws of the United States and Canada. Many companies have
encountered significant problems in protecting and defending such rights in foreign jurisdictions. Many countries, including certain countries in Europe, have
compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many countries limit the enforceability
of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially
diminish  the  value  of  the  patent.  Compulsory  licensing  of  life-saving  drugs  is  also  becoming  increasingly  popular  in  developing  countries  either  through
direct legislation or international initiatives. Such compulsory licenses could be extended to include some of our product candidates, which could limit our
potential  revenue  opportunities.  Moreover,  the  legal  systems  of  certain  countries,  particularly  certain  developing  countries,  do  not  favor  the  aggressive
enforcement of patent and other intellectual property protection, which makes it difficult to stop and prevent infringement.

Our patents and/or the patents that we license from others may be challenged, narrowed, invalidated, held to be unenforceable or circumvented, which could
limit our ability to stop competitors from marketing similar products or limit the length of term of patent protection we may have for our products. Changes in
either patent laws or in interpretations of patent laws in the U.S. and other countries may diminish the value of our intellectual property or narrow the scope of
our  patent  protection.  The  patents  issued  or  to  be  issued  to  us  may  not  provide  us  with  any  competitive  advantage  or  protect  us  against  competitors  with
similar technology. In addition, it is possible that third parties with products that are very similar to ours will circumvent our patents by means of alternate
designs or processes. We may have to rely on method-of-use, methods of manufacture and/or new-formulation protection for our compounds in development,
and any resulting products, which may not confer the same protection as claims to compounds per se.

12

In addition, our patents may be challenged by third parties in patent litigation, which is becoming widespread in the biopharmaceutical industry. There may be
prior art of which we are not aware that may affect the validity or enforceability of a patent claim. There may also be prior art of which we are aware, but
which we do not believe affects the validity or enforceability of a claim, which may, nonetheless, ultimately be found to affect the validity or enforceability of
a claim. No assurance can be given that our patents would, if challenged, be held by a court to be valid or enforceable or that a competitor's technology or
product would be found by a court to infringe our patents. Our granted patents could also be challenged and revoked in U.S.  post-grant proceedings as well
as in opposition or nullity proceedings in certain countries outside the U.S.  In addition, we may be required to disclaim part of the term of certain patents.

Patent  applications  relating  to  or  affecting  our  business  have  been  filed  by  a  number  of  pharmaceutical  and  biopharmaceutical  companies  and  academic
institutions. A number of the technologies in these applications or patents may conflict with our technologies, patents or patent applications, and any such
conflict could reduce the scope of patent protection that we could otherwise obtain. Because patent applications in the U.S. and many other jurisdictions are
typically not published until eighteen months after their first effective filing date, or in some cases not at all, and because publications of discoveries in the
scientific literature often lag behind actual discoveries, we cannot be certain that we were the first to make the inventions claimed in issued patents or pending
patent applications, or that we were the first to file for protection of the inventions set forth in the patent applications. If a third party has also filed a patent
application in the U.S.  covering our product candidates or a similar invention, we may have to participate in adversarial proceedings, such as interferences
and deviation proceedings, before the United States Patent and Trademark Office and/or applicable adjudicators to determine which party is entitled to a U.S.
patent claiming the disputed invention. The costs of these proceedings could be substantial and it is possible that our efforts could be unsuccessful, resulting
in a loss of our U.S. patent position.

We also rely on trade secrets and proprietary know-how to protect our intellectual property. If we are unable to protect the confidentiality of our proprietary
information and know-how, the value of our technology and products could be adversely affected. We seek to protect our unpatented proprietary information
in  part  by  requiring  our  employees,  consultants,  outside  scientific  collaborators  and  sponsored  researchers  and  other  advisors  to  enter  into  confidentiality
agreements.  These  agreements  provide  that  all  confidential  information  developed  or  made  known  to  the  individual  during  the  course  of  the  individual's
relationship with us is to be kept confidential and not disclosed to third parties except in specific circumstances. In the case of our employees, the agreements
provide that all of the technology that is conceived by the individual during the course of employment is our exclusive property. These agreements may not
provide meaningful protection or adequate remedies in the event of unauthorized use or disclosure of our proprietary information. In addition, it is possible
that  third  parties  could  independently  develop  proprietary  information  and  techniques  substantially  similar  to  ours  or  otherwise  gain  access  to  our  trade
secrets.  If  we  are  unable  to  protect  the  confidentiality  of  our  proprietary  information  and  know-how,  competitors  may  be  able  to  use  this  information  to
develop products that compete with our products and technologies, which could adversely impact our business.

We currently have the right to use certain patents and technologies under license agreements with third parties. Our failure to comply with the requirements of
one or more of our license agreements could result in the termination of such agreements, which could cause us to terminate the related development program
and cause a complete loss of our investment in that program. Inventions claimed in certain in-licensed patents may have been made with funding from the
U.S.    government  and  may  be  subject  to  the  rights  of  the  U.S.    government  and  we  may  be  subject  to  additional  requirements  in  the  event  we  seek  to
commercialize or manufacture product candidates incorporating such in-licensed technology.

As a result of the foregoing factors, we may not be able to rely on our intellectual property to protect our products in the marketplace.

We may infringe the intellectual property rights of others.

Our commercial success depends significantly on our ability to operate without infringing the patents and other intellectual property rights of third parties.
There could be issued patents of which we are not aware that our products or methods may be found to infringe, or patents of which we are aware and believe
we  do  not  infringe  but  which  we  may  ultimately  be  found  to  infringe.  Moreover,  patent  applications  and  their  underlying  discoveries  are  in  some  cases
maintained in secrecy until patents are issued. Because patents can take many years to issue, there may be currently pending applications of which we are
unaware that may later result in issued patents that our products or technologies are found to infringe. Moreover, there may be published pending applications
that do not currently include a claim covering our products or technologies but which nonetheless provide support for a later drafted claim that, if issued, our
products or technologies could be found to infringe.

If we infringe or are alleged to infringe intellectual property rights of third parties, it will adversely affect our business. Third parties may own or control these
patents  or  patent  applications  in  the  U.S.  and  abroad.  These  third  parties  could  bring  claims  against  us  or  our  collaborators  that  would  cause  us  to  incur
substantial expenses and, if successful against us, could cause us to pay substantial damages. Further, if a patent infringement suit were brought against us or
our collaborators, we or they could be

13

forced to stop or delay research, development, manufacturing or sales of the product or product candidate that is the subject of the suit.

The biopharmaceutical industry has produced a proliferation of patents, and it is not always clear to industry participants, including us, which patents cover
various  types  of  products.  The  coverage  of  patents  is  subject  to  interpretation  by  the  courts,  and  the  interpretation  is  not  always  uniform.  In  the  event  of
infringement or violation of another party's patent or other intellectual property rights, we may not be able to enter into licensing arrangements or make other
arrangements at a reasonable cost. Any inability to secure licenses or alternative technology could result in delays in the introduction of our products or lead
to prohibition of the manufacture or sale of products by us or our partners and collaborators.

Patent litigation is costly and time consuming and may subject us to liabilities.

If we become involved in any patent litigation, interference, opposition, re-examination or other administrative proceedings we will likely incur substantial
expenses  in  connection  therewith,  and  the  efforts  of  our  technical  and  management  personnel  will  be  significantly  diverted.  In  addition,  an  adverse
determination in litigation could subject us to significant liabilities.

We may not obtain trademark registrations for our current or future products.

We  have  filed  applications  for  trademark  registrations,  including  Macrilen™  (macimorelin),  in  various  jurisdictions,  including  the  U.S.  We  may  file
applications for other possible trademarks for current or future products in the future. No assurance can be given that any of our trademarks will be registered
in the U.S. or elsewhere, or that the use of any registered or unregistered trademarks will confer a competitive advantage in the marketplace.

We rely on third parties to conduct, supervise and monitor our clinical trials, and those third parties may not perform satisfactorily.

We are not currently conducting any clinical trials but we may decide to do so in the future. We rely on third parties such as contract resource organizations,
medical institutions and clinical investigators to enroll qualified patients and to conduct, supervise and monitor our clinical trials. Our reliance on these third
parties for clinical development activities reduces our control over these activities. Our reliance on these third parties, however, does not relieve us of our
regulatory  responsibilities,  including  ensuring  that  our  clinical  trials  are  conducted  in  accordance  with  Good  Clinical  Practice  guidelines  and  the
investigational  plan  and  protocols  contained  in  an  Investigational  New  Drug  application  to  the  FDA,  or  a  comparable  foreign  regulatory  submission.
Furthermore, these third parties may also have relationships with other entities, some of which may be our competitors. In addition, they may not complete
activities on schedule, or may not conduct our preclinical studies or clinical trials in accordance with regulatory requirements or our trial design. If these third
parties do not successfully carry out their contractual duties or meet expected deadlines, our efforts to obtain regulatory approvals for, and to commercialize,
our products may be delayed or prevented.

In carrying out our operations, we are dependent on a stable and consistent supply of ingredients and raw materials.

There can be no assurance that we, our contract manufacturers or our licensees, will be able, in the future, to continue to purchase products from our current
suppliers or any other supplier on terms that are favorable or similar to current terms or at all. An interruption in the availability of certain raw materials or
ingredients,  or  significant  increases  in  the  prices  we  pay  for  them,  could  have  a  material  adverse  effect  on  our  business,  financial  condition,  liquidity  and
operating results.

The failure to perform satisfactorily by third parties upon which we expect to rely to manufacture and supply products may lead to supply shortfalls.

We expect to rely on third parties to manufacture and supply marketed products. We also have or may have certain supply obligations vis-à-vis our existing
and  potential  licensees,  who  are  or  will  be  responsible  for  the  marketing  of  the  products.  To  be  successful,  our  current  or  future  products  have  to  be
manufactured in commercial quantities in compliance with quality controls and regulatory requirements. Even though it is our objective to minimize such risk
by introducing alternative suppliers to ensure a constant supply at all times, there are a limited number of contract manufacturers or suppliers that are capable
of manufacturing our current or future products or the materials used in their manufacture. If we are unable to do so ourselves or to arrange for third-party
manufacturing or supply of these products or materials, or to do so on commercially reasonable terms, we may not be able to complete development of these
products or to commercialize them ourselves or through our licensees. Reliance on third-party manufacturers entails risks to which we would not be subject if
we manufactured products ourselves, including reliance on the third party for regulatory compliance, the possibility of breach of the manufacturing agreement
by the third party because of factors beyond our control, and the possibility of termination or non-renewal of the agreement by the third party, based on its
own business priorities, at a time that is costly or inconvenient for us.

We are subject to intense competition for our skilled personnel, and the loss of key personnel or the inability to attract additional personnel could impair
our ability to conduct our operations.

14

We are highly dependent on our management and our clinical, regulatory and scientific staff, the loss of whose services might adversely impact our ability to
achieve our objectives. Recruiting and retaining qualified management and clinical, scientific and regulatory personnel is critical to our success. Reductions in
our staffing levels have eliminated redundancies in key capabilities and skill sets among our full-time staff and required us to rely more heavily on outside
consultants and third parties. We have been unable to increase the compensation of our associates to the extent required to remain fully competitive for their
services, which increased our employee retention risk. The competition for qualified personnel in the biopharmaceutical field is intense, and if we are not able
to continue to attract and retain qualified personnel and/or maintain positive relationships with our outside consultants, we may not be able to achieve our
strategic and operational objectives.

We are currently subject to the following litigation matters and we may be subject to similar or other litigation in the future.

Securities class action litigation

We and certain of our current and former officers are defendants in a class-action lawsuit pending in the U.S. District Court for the District of New Jersey
(the "Court"), brought on behalf of shareholders of the Company. The lawsuit alleges violations of the Securities Exchange Act of 1934 (the "Exchange Act")
in  connection  with  allegedly  false  and  misleading  statements  made  by  the  defendants  between  April  2,  2012  and  November  6,  2014  (the  "Class  Period"),
regarding the safety and efficacy of Macrilen™ (macimorelin), and the prospects for the approval of the Company's NDA for the product by the FDA. The
plaintiffs represent a class comprised of purchasers of our Common Shares during the Class Period and seek damages, costs and expenses and such other
relief as determined by the Court. On September 14, 2015, the Court dismissed the lawsuit stating that the plaintiffs failed to state a claim, but granted the
plaintiffs leave to amend. On October 14, 2015, the plaintiffs filed a second amended complaint against us. We subsequently filed a motion to dismiss because
we believed that the second amended complaint also failed to state a claim.

On March 2, 2016, the Court issued an order granting our motion to dismiss the complaint in part and denying it in part.  The Court dismissed certain of our
current and former officers from the lawsuit.  The Court allowed the claim that we omitted material facts from our public statements during the Class Period
to proceed against us and our former Chief Executive Officer, who departed in 2013, while dismissing such claims against other current and former officers. 
The Court also allowed a claim for "controlling person" liability to proceed against certain current and former officers.  On March 16, 2016, we filed a motion
for reconsideration of the Court's March 2, 2016 order and on April 6, 2016 we filed an answer to the second amended complaint. On June 30, 2016, the
Court issued an order denying our motion for reconsideration. On February 28, 2018, the Court granted a motion for class certification which we appealed.
We  filed  an  interlocutory  petition  for  review  on  March  14,  2018.    Lead  Plaintiff’s  opposition  to  the  petition  was  due  on  Monday,  March  26,  2018.  The
discovery process has commenced and is on-going. While we believe we have meritorious defenses and intend to continue to defend this lawsuit vigorously,
we cannot predict the outcome.

Litigation pertaining to former officers of the Company

In late July 2017, we terminated for cause the employment of Mr. David A. Dodd, the former President and Chief Executive Officer of the Company and we
also terminated the employment of Mr. Philip A. Theodore, the former Senior Vice President, Chief Administrative Officer, General Counsel and Corporate
Secretary  of  the  Company.  All  outstanding  stock  options  held  by  both  former  officers  were  cancelled  effective  as  of  their  respective  termination  dates,  in
accordance with the provisions of our Stock Option Plan (as defined below).

On August 3, 2017, we announced that we had filed a lawsuit against both Messrs. Dodd and Theodore for damages suffered by us for breach of confidence
and/or breach of fiduciary duty in an amount to be determined prior to trial. We are also seeking, among other things, an injunction to prevent both Messrs.
Dodd and Theodore from: (i) continuing to use our confidential and proprietary information without authorization; and (ii) mounting a proxy contest that will
be premised upon the breaches of fiduciary and statutory duties and breaches of confidence alleged in the lawsuit. We engaged external counsel to conduct an
internal investigation related to this lawsuit, which is still ongoing. Messrs. Dodd and Theodore have requested indemnification advances from the Company
to cover their expenses in defending this lawsuit. On December 21, 2017, Messrs. Dodd and Theodore brought a counterclaim against the Company and its
Chair, Carolyn Egbert, in the amount of CAN$6.0 million alleging, among other things, that defamatory statements were made against Messrs. Dodd and
Theodore.  The  Company  and  its  Chair  consider  the  counterclaim  against  them  to  be  entirely  without  merit,  and  intend  to  vigorously  defend  against  the
counterclaim.

On August 4, 2017, Mr. Dodd filed a lawsuit in the Court of Common Pleas of South Carolina against us for damages of approximately U.S.$1.7 million,
alleging  breach  of  his  employment  contract.  He  is  also  requesting  that  all  of  his  outstanding  stock  options  vest  effective  upon  his  termination  date.  On
September  5,  2017,  the  lawsuit  in  the  Court  of  Common  Pleas  of  South  Carolina  was  moved  to  the  Federal  Court  in  South  Carolina.  The  court  has  set  a
scheduling order, with discovery set to end on June 29, 2018. While we believe we have meritorious defenses and intend to continue to defend this lawsuit
vigorously, we cannot predict the outcome.

15

Cogas litigation

Cogas Consulting, LLC ('Cogas') filed a lawsuit against the Company in state court in Fulton County, Georgia on February 2, 2018. Cogas alleges that its
employee (and sole shareholder) John Sharkey is entitled to a "success fee" commission on the Strongbridge License Agreement. Cogas is claiming damages
in the form of a lost commission on the transaction. Cogas claims its commission is 5% on payments the Company receives within the first three years after
January 14, 2018. Cogas alleges it is entitled to 5% of the $24 million that Strongbridge already paid the Company, plus 5% of any royalty Strongbridge pays
the Company through January 17, 2021. The Company plans to vigorously defend this matter.

Furthermore,  we  may,  from  time  to  time,  be  a  party  to  other  litigation  in  the  normal  course  of  business.  Monitoring  and  defending  against  legal  actions,
whether  or  not  meritorious,  is  time-consuming  for  our  management  and  detracts  from  our  ability  to  fully  focus  our  internal  resources  on  our  business
activities. In addition, legal fees and costs incurred in connection with such activities may be significant and we could, in the future, be subject to judgments
or enter into settlements of claims for significant monetary damages. A decision adverse to our interests could result in the payment of substantial damages
and could have a material adverse effect on our cash flow, results of operations and financial position.

With  respect  to  any  litigation,  our  insurance  may  not  reimburse  us  or  may  not  be  sufficient  to  reimburse  us  for  the  expenses  or  losses  we  may  suffer  in
contesting and concluding such lawsuit. Substantial litigation costs, including the substantial self-insured retention that we are required to satisfy before any
insurance applies to a claim, unreimbursed legal fees or an adverse result in any litigation may adversely impact our business, operating results or financial
condition. We believe that our directors' and officers' liability insurance will cover our potential liability with respect to the securities class-action lawsuit and
the litigation pertaining to former officers of the Company described above; however, the insurer has reserved its rights to contest the applicability of the
insurance to such claims and the limits of the insurance may be insufficient to cover our eventual liability.

We are subject to the risk of product liability claims, for which we may not have or may not be able to obtain adequate insurance coverage.

The  use  of  Macrilen™  (macimorelin)  on  human  participants  in  our  clinical  trials  subjects  us  to  the  risk  of  liability  to  such  participants,  who  may  suffer
unintended consequences. The sale and use of Macrilen™ (macimorelin) will involve the risk of product liability claims and associated adverse publicity.
Product liability claims might be made against us directly by patients, healthcare providers or pharmaceutical companies or others selling, buying or using our
products. We attempt to manage our liability risks by means of insurance. We maintain insurance covering our liability for our preclinical and clinical studies
as well as products liability insurance. However, we may not have or be able to obtain or maintain sufficient and affordable insurance coverage, including
coverage for potentially very significant legal expenses, and without sufficient coverage any claim brought against us could have a materially adverse effect
on our business, financial condition or results of operations.

Our business involves the use of hazardous materials. We are required to comply with environmental and occupational safety laws regulating the use of
such materials. If we violate these laws, we could be subject to significant fines, liabilities or other adverse consequences.

Our  discovery  and  development  processes  involve  the  controlled  use  of  hazardous  materials.  We  are  subject  to  federal,  provincial  and  local  laws  and
regulations governing the use, manufacture, storage, handling and disposal of such materials and certain waste products. The risk of accidental contamination
or injury from these materials cannot be eliminated. In the event of an accident or a failure to comply with environmental or occupational safety laws, we
could be held liable for any damages that result, and any such liability could exceed our resources. We may not be adequately insured against this type of
liability. We may be required to incur significant costs to comply with environmental laws and regulations in the future, and our operations, business or assets
may be materially adversely affected by current or future environmental laws or regulations.

We are a holding company, and claims of creditors of our subsidiaries will generally have priority as to the assets of such subsidiaries over our claims and
those of our creditors and shareholders. In addition, we may be required to fund obligations of AEZS Germany.

Aeterna  Zentaris  Inc.  is  a  holding  company  and  a  substantial  portion  of  our  non-cash  assets  is  the  share  capital  of  our  subsidiaries.  AEZS  Germany,  our
principal  operating  subsidiary,  based  in  Frankfurt,  Germany,  holds  most  of  our  intellectual  property  rights.  Because  Aeterna  Zentaris  Inc.  is  a  holding
company, our obligations to our creditors are structurally subordinated to all existing and future liabilities of our subsidiaries, which may incur additional or
other liabilities and/or obligations. Therefore, our rights and the rights of our creditors to participate in any distribution of the assets of any subsidiary in the
event  that  such  subsidiary  were  to  be  liquidated  or  reorganized  or  in  the  event  of  any  bankruptcy  or  insolvency  proceeding  relating  to  or  involving  such
subsidiary, and therefore the rights of the holders of our Common Shares to participate in those assets, are subject to the prior claims of such subsidiary's
creditors. To the extent that we may be a creditor with recognized claims against any such subsidiary,

16

our claims would still be subject to the prior claims of our subsidiary's creditors to the extent that they are secured or senior to those held by us.

Holders of our Common Shares are not creditors of our subsidiaries. Claims to the assets of our subsidiaries will derive from our own ownership interest in
those operating subsidiaries. Claims of our subsidiaries' creditors will generally have priority as to the assets of such subsidiaries over our own ownership
interest claims and will therefore have priority over the holders of our Common Shares. Our subsidiaries' creditors may from time to time include general
creditors,  trade  creditors,  employees,  secured  creditors,  taxing  authorities,  and  creditors  holding  guarantees.  Accordingly,  in  the  event  of  any  foreclosure,
dissolution,  winding-up,  liquidation  or  reorganization,  or  a  bankruptcy,  insolvency  or  creditor  protection  proceeding  relating  to  us  or  our  property,  or  any
subsidiary, there can be no assurance as to the value, if any, that would be available to holders of our Common Shares. In addition, any distributions to us by
our subsidiaries could be subject to monetary transfer restrictions in the jurisdictions in which our subsidiaries operate.

We provided the Letter of Comfort to AEZS Germany in 2017 and prior years because German law imposes an obligation on the managing director of AEZS
Germany  to  institute  insolvency  proceedings  if  the  managing  director  concludes  that  AEZS  Germany  is  insolvent  because  it  is  either  illiquid  or  "over-
indebted". The purpose of the Letter of Comfort is to preclude the managing director from determining that AEZS Germany is illiquid or over-indebted. The
Letter of Comfort will be sufficient for that purpose only as long as the managing director reasonably believes that we will be able to honor our obligations
under the Letter of Comfort. If we fail to renew the Letter of Comfort or if the managing director concludes that we will be unable to honor our obligations
under  the  Letter  of  Comfort,  the  managing  director  of  AEZS  Germany  may  determine  that  he  or  she  is  obligated  to  institute  insolvency  proceedings  in
Germany for AEZS Germany.

Because we are a holding company and because we may have an obligation to advance funds to AEZS Germany to prevent it from becoming either illiquid or
over-indebted, we may be required to use our cash to fund payments by AEZS Germany to its creditors. Therefore, in the event of any winding-up, liquidation
or reorganization, or a bankruptcy or insolvency proceeding relating to us or our property, there can be no assurance as to the value or assets, if any, that
would be available to holders of our Common Shares because we may be required to advance cash to AEZS Germany.

It may be difficult for U.S. investors to obtain and enforce judgments against us because of our Canadian incorporation and German presence.

We are a company existing under the laws of Canada. A number of our directors and officers, and certain of the experts named herein, are residents of Canada
or  otherwise  reside  outside  the  U.S.,  and  all  or  a  substantial  portion  of  their  assets,  and  a  substantial  portion  of  our  assets,  are  located  outside  the  U.S.
Consequently, although we have appointed an agent for service of process in the U.S., it may be difficult for investors in the U.S. to bring an action against
such directors, officers or experts or to enforce against those persons or us a judgment obtained in a U.S. court predicated upon the civil liability provisions of
federal  securities  laws  or  other  laws  of  the  U.S.    Investors  should  not  assume  that  foreign  courts  (i)  would  enforce  judgments  of  U.S.  courts  obtained  in
actions against us or such directors, officers or experts predicated upon the civil liability provisions of the U.S.  federal securities laws or the securities or
"blue sky" laws of any state within the U.S. or (ii) would enforce, in original actions, liabilities against us or such directors, officers or experts predicated
upon the U.S. federal securities laws or any such state securities or "blue sky" laws.

We are subject to various internal control reporting requirements under applicable Canadian securities laws and the Sarbanes-Oxley Act in the U.S. We
can provide no assurance that we will at all times in the future be able to report that our internal controls over financial reporting are effective.

As  a  public  company,  we  are  required  to  comply  with  Section  404  of  the  U.S.  Sarbanes-Oxley  Act  ("Section  404")  and  National  Instrument  52-109  -
Certification of Disclosure in Issuers' Annual and Interim Filings of the Canadian securities administrators. In any given year, we cannot be certain as to the
time of completion of our internal control evaluation, testing and remediation actions or of their impact on our operations. Upon completion of this process,
we may identify control deficiencies of varying degrees of severity under applicable SEC and Public Company Accounting Oversight Board (U.S.) rules and
regulations.  As  a  public  company,  we  are  required  to  report,  among  other  things,  control  deficiencies  that  constitute  material  weaknesses  or  changes  in
internal controls that, or that are reasonably likely to, materially affect internal controls over financial reporting. A "material weakness" is a deficiency, or a
combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual
consolidated financial statements will not be prevented or detected on a timely basis. If we fail to comply with the requirements of Section 404 or similar
Canadian requirements or if we report a material weakness, we might be subject to regulatory sanction and investors may lose confidence in our consolidated
financial statements, which may be inaccurate if we fail to remedy such material weakness.

It is possible that we may be a passive foreign investment company, which could result in adverse tax consequences to U.S. investors.

17

Adverse  U.S.  federal  income  tax  rules  apply  to  "U.S.  Holders"  (as  defined  in  "Item  10.E  -  Taxation  -  Certain  Material  U.S.  Federal  Income  Tax
Considerations" in this Annual Report on Form 20-F) who directly or indirectly hold Common Shares of a passive foreign investment company ("PFIC"). We
will be classified as a PFIC for U.S. federal income tax purposes for a taxable year if (i) at least 75% of our gross income is "passive income" or (ii) at least
50% of the average value of our assets, including goodwill (based on annual quarterly average), is attributable to assets which produce passive income or are
held for the production of passive income.

We  believe  that  we  were  a  PFIC  for  the  2015  taxable  year,  but  were  not  a  PFIC  for  the  2016  and  2017  taxable  years.  However,  the  PFIC  determination
depends on the application of complex U.S. federal income tax rules concerning the classification of our assets and income for this purpose, and these rules
are uncertain in some respects. In addition, the fair market value of our assets may be determined in large part by the market price of our Common Shares,
which is likely to fluctuate, and the composition of our income and assets will be affected by how, and how quickly, we spend any cash that is raised in any
financing transaction. No assurance can be provided that we will not be classified as a PFIC for the 2018 taxable year and for any future taxable year.

If we are a PFIC for any taxable year during which a U.S. Holder holds Common Shares, we generally would continue to be treated as a PFIC with respect to
that U.S. Holder for all succeeding years during which the U.S. Holder holds such Common Shares, even if we ceased to meet the threshold requirements for
PFIC status. PFIC characterization could result in adverse U.S. federal income tax consequences to U.S. Holders. In particular, absent certain elections, a U.S.
Holder would generally be subject to U.S. federal income tax at ordinary income tax rates, plus a possible interest charge, in respect of a gain derived from a
disposition of our Common Shares, as well as certain distributions by us. If we are treated as a PFIC for any taxable year, a U.S. Holder may be able to make
an election to "mark to market" Common Shares each taxable year and recognize ordinary income pursuant to such election based upon increases in the value
of the Common Shares. In addition, U.S. Holders may mitigate the adverse tax consequences of the PFIC rules by making a "qualified electing fund" ("QEF")
election; however, there can be no assurance that the Company will satisfy the record keeping requirements applicable to a QEF or that it will provide the
information regarding its income that would be necessary for a U.S. Holder to make a QEF election.

If the Company is a PFIC, U.S. Holders will generally be required to file an annual information return with the Internal Revenue Service (the "IRS") (on IRS
Form 8621, which PFIC shareholders will be required to file with their U.S. federal income tax or information returns) relating to their ownership of Common
Shares. This filing requirement is in addition to any preexisting reporting requirements that apply to a U.S. Holder's interest in a PFIC (which this requirement
does not affect).

For a more detailed discussion of the potential tax impact of us being a PFIC, see "Item 10.E - Taxation - Material U.S. Federal Income Tax Considerations"
in this Annual Report on Form 20-F. The PFIC rules are complex. U.S. Holders should consult their tax advisors regarding the potential application of the
PFIC regime and any reporting obligations to which they may be subject under that regime.

Our net operating losses may be limited for U.S. federal income tax purposes under Section 382 of the Internal Revenue Code.

If  a  corporation  with  net  operating  losses  ("NOLs")  undergoes  an  "ownership  change"  within  the  meaning  of  Section  382  of  the  United  States  Internal
Revenue Code of 1986, as amended, then such corporation's use of such "pre-change" NOLs to offset income incurred following such ownership change may
be limited. Such limitation also may apply to certain losses or deductions that are "built-in" (i.e., attributable to periods prior to the ownership change but not
yet taken into account for tax purposes) as of the date of the ownership change that are subsequently recognized. An ownership change generally occurs when
there is either (i) a shift in ownership involving one or more "5% shareholders"; or (ii) an "equity structure shift" and, as a result, the percentage of stock of
the corporation owned by one or more 5% shareholders (based on value) has increased by more than 50 percentage points over the lowest percentage of stock
of the corporation owned by such shareholders during the "testing period" (generally the 3 years preceding the testing date). In general, if such change occurs,
the corporation's ability to utilize its net operating loss carry-forwards and certain other tax attributes would be subject to an annual limitation, as described
below. The unused portion of any such net operating loss carry-forwards or tax attributes each year is carried forward, subject to the same limitation in future
years. The impact of an ownership change on state NOL carryforwards may vary from state to state. Recent legislation added several limitations to the ability
to claim deductions for NOLs, including a deduction limit equal to 80% of taxable income and a restriction on NOL carryback deductions.

We may incur losses associated with foreign currency fluctuations.

Our operations are in many instances conducted in currencies other than our functional currency or the functional currencies of our subsidiaries. Fluctuations
in the value of currencies could cause us to incur currency exchange losses. We do not currently employ a hedging strategy against exchange rate risk. We
cannot assert with any assurance that we will not suffer losses as a result of unfavorable fluctuations in the exchange rates between the U.S. dollar, the euro,
the Canadian dollar and other currencies.

18

Legislative  actions,  new  accounting  pronouncements  and  higher  insurance  costs  may  adversely  impact  our  future  financial  position  or  results
of operations.

Changes in financial accounting standards or implementation of accounting standards may cause adverse, unexpected revenue or expense fluctuations and
affect  our  financial  position  or  results  of  operations.  New  pronouncements  and  varying  interpretations  of  pronouncements  have  occurred  with  greater
frequency and are expected to occur in the future, and we may make or be required to make changes in our accounting policies in the future. Compliance with
changing regulations of corporate governance and public disclosure, notably with respect to internal controls over financial reporting, may result in additional
expenses. Changing laws, regulations and standards relating to corporate governance and public disclosure are creating uncertainty for companies such as
ours, and insurance costs are increasing as a result of this uncertainty.

Data security breaches may disrupt our operations and adversely affect our operating results.

Our network security and data recovery measures and those of third parties with which we contract, may not be adequate to protect against computer viruses,
cyber-attacks, breaches, and similar disruptions from unauthorized tampering with our computer systems. The misappropriation, theft, sabotage or any other
type of security breach with respect to any of our proprietary and confidential information that is electronically stored, including research or clinical data,
could cause interruptions in our operations, could result in a material disruption of our clinical activities and business operations and could expose us to third-
party legal claims. Furthermore, we could be required to make substantial expenditures of resources to remedy the cause of cyber-attacks or break-ins. This
disruption  could  have  a  material  adverse  impact  on  our  business,  operating  results  and  financial  condition.  Additionally,  any  break-in  or  trespass  of  our
facilities that results in the misappropriation, theft, sabotage or any other type of security breach with respect to our proprietary and confidential information,
including  research  or  clinical  data,  or  that  results  in  damage  to  our  R&D  equipment  and  assets  could  have  a  material  adverse  impact  on  our  business,
operating results, and financial condition.

Our  business  processes  personal  information,  both  in  connection  with  clinical  activities  and  our  employees.  The  use  of  this  information  is  critical  to  our
operations and innovation, including the development of our products, as well as management of our employees. New and evolving regulations, such as the
European Union General Data Protection Regulation, could bring increased scrutiny of our data management in the future. Any cyber-attacks or other failure
to protect critical and sensitive systems and information could damage our reputation, prompt litigation or lead to regulatory sanctions, all of which could
materially affect our financial condition and results of operation.

19

Risks Relating to our Common Shares

Our Common Shares may be delisted from the NASDAQ Capital Market ("NASDAQ") or the Toronto Stock Exchange ("TSX"), which could affect their
market price and liquidity. If our Common Shares were to be delisted, investors may have difficulty in disposing of their shares.

Our Common Shares are currently listed on both NASDAQ and TSX under the symbol "AEZS". We must meet continuing listing requirements to maintain
the  listing  of  our  Common  Shares  on  NASDAQ  and  TSX.  For  continued  listing,  NASDAQ  requires,  among  other  things,  that  listed  securities  maintain  a
minimum closing bid price of not less than $1.00 per share. There can be no assurance that the market price of our Common Shares will not fall below $1.00
in the future or that, if it does, we will regain compliance with the minimum bid price requirement.

In addition to the minimum bid price requirement, the continued listing rules of NASDAQ require us to meet at least one of the following listing standards:
(i) stockholders' equity of at least $2.5 million, (ii) market value of listed securities (calculated by multiplying the daily closing bid price of our Common
Shares by our total outstanding Common Shares) of at least $35 million or (iii) net income from continuing operations (in the latest fiscal year or in two of the
last  three  fiscal  years)  of  at  least  $500,000  (collectively,  the  "Additional  Listing  Standards").  If  we  fail  to  meet  at  least  one  of  the  Additional  Listing
Standards, our Common Shares may be subject to delisting after the expiration of the period of time, if any, that we are allowed for regaining compliance.

As at December 31, 2017, we were not in compliance with the continued listing standards of NASDAQ. However, in January 2018, we received an upfront
milestone payment of $24 million pursuant to the Strongbridge License Agreement and we believe that the impact of this payment will cure any default of the
continuing  listing  standards  of  NASDAQ  that  might  have  been  present  as  at  December  31,  2017,  however  there  is  no  assurance  that  we  will  obtain  and
maintain compliance or that NASDAQ will determine that we have achieved compliance.

There can be no assurance that our Common Shares will remain listed on NASDAQ or TSX. If we fail to meet any of NASDAQ's or TSX's continued listing
requirements, our Common Shares may be delisted. Any delisting of our Common Shares may adversely affect a shareholder's ability to dispose, or obtain
quotations as to the market value, of such shares.

Our share price is volatile, which may result from factors outside of our control.

Our valuation and share price since the beginning of trading after our initial listings, first in Canada and then in the U.S., have had no meaningful relationship
to current or historical financial results, asset values, book value or many other criteria based on conventional measures of the value of shares.

Between January 1, 2017 and December 31, 2017, the closing price of our Common Shares ranged from $0.84 to $3.65 per share on NASDAQ and from
C$1.13 to C$4.81 per share on TSX. Our share price may be affected by developments directly affecting our business and by developments out of our control
or unrelated to us. The stock market generally, and the biopharmaceutical sector in particular, are vulnerable to abrupt changes in investor sentiment. Prices of
shares  and  trading  volume  of  companies  in  the  biopharmaceutical  industry  can  swing  dramatically  in  ways  unrelated  to,  or  that  bear  a  disproportionate
relationship to, operating performance. Our share price and trading volume may fluctuate based on a number of factors including, but not limited to:

•

•

•

•

•

•

•

•

•

•

clinical and regulatory developments regarding our product candidates;

delays in our anticipated development or commercialization timelines;

developments regarding current or future third-party collaborators and licensee(s);

announcements by us regarding technological, product development or other matters;

arrivals or departures of key personnel;

governmental or regulatory action affecting our product candidates and our competitors' products in the U.S., Canada and other countries;

developments or disputes concerning patent or proprietary rights;

actual or anticipated fluctuations in our revenues or expenses;

general market conditions and fluctuations for the emerging growth and biopharmaceutical market sectors; and

economic conditions in the U.S., Canada or abroad.

20

Our listing on both NASDAQ and TSX may increase price volatility due to various factors, including different ability to buy or sell our Common Shares,
different market conditions in different capital markets and different trading volumes. In addition, low trading volume may increase the price volatility of our
Common Shares. A thin trading market could cause the price of our Common Shares to fluctuate significantly more than the stock market as a whole.

We do not intend to pay dividends in the near future.

To  date,  we  have  not  declared  or  paid  any  dividends  on  our  Common  Shares.  We  currently  intend  to  retain  our  future  earnings,  if  any,  to  finance  further
research and the overall commercial expansion of our business. As a result, the return on an investment in our Common Shares will depend upon any future
appreciation in value. There is no guarantee that our Common Shares or any of our other securities will appreciate in value or even maintain the price at
which shareholders have purchased them.

Future issuances of securities and hedging activities may depress the trading price of our Common Shares.

Any additional or future issuance of Common Shares or Convertible Securities, including the issuance of Common Shares upon the exercise of stock options
and upon the exercise of warrants, could dilute the interests of our existing shareholders, and could substantially decrease the trading price of our Common
Shares.

We may issue equity securities in the future for a number of reasons, including to finance our operations and business strategy, to satisfy our obligations upon
the exercise of options or warrants or for other reasons. Our Stock Option Plan generally permits us to have outstanding, at any given time, stock options that
are  exercisable  for  a  maximum  number  of  Common  Shares  equal  to  11.4%  of  all  then  issued  and  outstanding  Common  Shares.  As  at  March  27,  2018,
there were:

16,440,760   Common Shares issued and outstanding

—   Preferred Shares issued and outstanding

3,417,840   Common Shares issuable upon exercise of outstanding warrants

711,252   Stock Options outstanding

1,162,995   Additional Common Shares available for future grants under our stock option plan

In addition, the price of our Common Shares could also be affected by possible sales of Common Shares by investors who view other investment vehicles as
more attractive means of equity participation in us and by hedging or arbitrage trading activity that may develop involving our Common Shares. This hedging
or arbitrage could, in turn, affect the trading price of our Common Shares.

In the event we were to lose our foreign private issuer status as of June 30 of a given financial year, we would be required to comply with the Exchange
Act's domestic reporting regime, which could cause us to incur additional legal, accounting and other expenses.

In order to maintain our current status as a foreign private issuer, either (1) a majority of our Common Shares must not be either directly or indirectly owned
of record by residents of the U.S. or (2) (a) a majority of our executive officers and of our directors must not be U.S. citizens or residents, (b) more than 50
percent of our assets cannot be located in the U.S. and (c) our business must be administered principally outside the U.S.

In  2017,  our  management  conducted  its  annual  assessment  of  the  various  facts  and  circumstances  underlying  the  determination  of  our  status  as  a  foreign
private issuer and, based on the foregoing, our management has determined that, as of the date of such determination and as of June 30, 2017, we continued to
be a foreign private issuer.

There can be no assurance, however, that we will remain a foreign private issuer either in 2018 or in future financial years.

If we were to lose our foreign private issuer status as of June 30 of any given financial year, we would be required to comply with the Exchange Act reporting
and other requirements applicable to U.S. domestic issuers, which are more detailed and extensive than the requirements for foreign private issuers. We may
also be required to make changes in our corporate governance practices in accordance with various SEC rules and NASDAQ listing standards. The regulatory
and compliance costs to us of complying with the reporting requirements applicable to a U.S. domestic issuer under U.S. securities laws may be higher than
the cost we have historically incurred as a foreign private issuer. In addition, if we were to lose our foreign private issuer status, we would no longer qualify
under the Canada-U.S. multijurisdictional disclosure system to benefit from being able to file registration statements on Form F-10 (even if we satisfy the
other conditions to eligibility), which could make it longer and more difficult to register our securities and raise funds by way of public, registered offerings in
the U.S., and we would become subject to "baby shelf" rules that place limitations on our ability to issue an amount of securities above a certain threshold
depending on our market capitalization and public float at a given point in time. As a result, we would expect that a potential loss of foreign private issuer
status at some

21

future point in time could increase our legal, financial reporting and accounting compliance costs, and it is difficult at this time to estimate by how much our
legal, financial reporting and accounting compliance costs may increase in such eventuality.

Our articles of incorporation contain "blank check" preferred share provisions, which could delay or impede an acquisition of our Company.

Our articles of incorporation, as amended, authorize the issuance of an unlimited number of "blank check" preferred shares, which could be issued by our
Board of Directors without shareholder approval and which may contain liquidation, dividend and other rights equivalent or superior to our Common Shares.
In addition, we have implemented in our constating documents an advance notice procedure for shareholder approvals to be brought before an annual meeting
of  our  shareholders,  including  proposed  nominations  of  persons  for  election  to  our  Board  of  Directors.  These  provisions,  among  others,  whether  alone  or
together, could delay or impede hostile takeovers and changes in control or changes in our management. Any provision of our constating documents that has
the effect of delaying or deterring a change in control could limit the opportunity for our shareholders to receive a premium for their Common Shares and
could also affect the price that some investors are willing to pay for our Common Shares.

Our business could be negatively affected as a result of the actions of activist shareholders.

Proxy contests have been waged against many companies in the biopharmaceutical industry over the last few years. If faced with a proxy contest, we may not
be able to successfully respond to the contest, which would be disruptive to our business. Even if we are successful, our business could be adversely affected
by a proxy contest because:

•

•

•

responding to proxy contests and other actions by activist shareholders may be costly and time‑consuming, and may disrupt our operations and divert the
attention of management and our employees;

perceived uncertainties as to the potential outcome of any proxy contest may result in our inability to consummate potential acquisitions, collaborations
or in‑licensing opportunities and may make it more difficult to attract and retain qualified personnel and business partners; and

if individuals that have a specific agenda different from that of our management or other members of our Board of Directors are elected to our board as a
result of any proxy contest, such an election may adversely affect our ability to effectively and timely implement our strategic plan and to create value for
our shareholders.

Business overview

On December 20, 2017, the FDA granted marketing approval for Macrilen™ (macimorelin) to be used in the diagnosis of patients with adult growth hormone
deficiency ("AGHD").

Macrilen™ (macimorelin), a ghrelin receptor agonist, is a novel orally-active small molecule that stimulates the secretion of growth hormone. Macrilen™
(macimorelin) has been granted orphan drug designation by the FDA for the evaluation of growth hormone deficiency. We own the worldwide rights to this
novel patented compound. Macrilen™ (macimorelin) is our proposed trade name for macimorelin. The proposed trade name was conditionally approved by
the FDA. On December 16, 2016, we were advised by the EMA that Macrilen™ was rejected as the proposed invented name for macimorelin because of its
similarity to the names of other medicines. On March 8, 2018, we applied for two new invented names for macimorelin: Macrilen ST and Macrilen GHST;
however, we are also evaluating alternative names given recent feedback received from the EMA.

On January 16, 2018, through AEZS Germany, we entered into the Strongbridge License Agreement. We received an upfront cash payment of $24,000,000
from  Strongbridge,  and,  for  as  long  as  Macrilen™  (macimorelin)  is  patent-protected,  the  Company  will  be  entitled  to  a  15%  royalty  on  net  sales  up  to
$75,000,000  and  an  18%  royalty  on  net  sales  above  $75,000,000.  Following  the  end  of  patent  protection  in  United  States  or  Canada  for  Macrilen™
(macimorelin), the Company will be entitled to a 5% royalty

23

on net sales in that country. In addition, the Company will also receive one-time payments from Strongbridge following the first achievement of the following
commercial milestone events:

•

•

•

•

•

$4,000,000 on achieving $25,000,000 annual net sales,

$10,000,000 on achieving $50,000,000 annual net sales,

$20,000,000 on achieving $100,000,000 annual net sales,

$40,000,000 on achieving $200,000,000 annual net sales, and

$100,000,000 on achieving $500,000,000 annual net sales.

Upon approval by the FDA of a pediatric indication for Macrilen™ (macimorelin), the Company will receive a one-time milestone payment of $5,000,000
from Strongbridge.

Strongbridge will fund 70% of the costs of a worldwide pediatric development program to be run by the Company with customary oversight from a joint
steering  committee.  The  joint  steering  committee  will  be  comprised  of  four  persons,  two  of  whom  will  be  appointed  by  each  of  Strongbridge  and  the
Company.

In 2017, we completed a Phase 3 study of the internally developed compound Zoptrex™ (zoptarelin doxorubicin), in the indication for advanced, recurrent
endometrial cancer, the results of which study are not supportive to pursue regulatory approval by the FDA. In light of the results of the Zoptrex™ study, our
focus has shifted entirely to the commercialization, either directly or through third parties, of Macrilen™ (macimorelin).

The commercial success of Macrilen™ (macimorelin) will depend on several factors, including, but not limited to, the receipt of approvals from the EMA and
similar  foreign  regulatory  authorities;  developing  appropriate  distribution  and  marketing  infrastructure  and  arrangements  for  our  product;  launching  and
growing commercial sales of the product; and acceptance of the product in the medical community, among patients and with third party payers. We are not
currently conducting any clinical studies.

We continue to explore various alternatives to monetize our rights to macimorelin in other countries around the globe.

We also continue to seek opportunities to in-license and acquire products. Our goal is to become a growth-oriented specialty biopharmaceutical company by
pursuing  successful  development,  commercialization  and  licensing  of  a  product  portfolio  achieving  successful  commercial  presence  and  growth,  while
consistently delivering value to our shareholders, employees and the medical providers and patients who will benefit from our products.

Our Business Strategy

Our  primary  business  strategy  is  to  finalize  the  development,  manufacturing,  registration  and  commercialization  of  Macrilen™  (macimorelin)  through  the
Strongbridge  License  Agreement  in  the  United  States  and  Canada.  We  continue  to  explore  various  alternatives  to  monetize  our  rights  to  Macrilen™
(macimorelin) in other countries around the globe, including whether to find other license partners in these jurisdictions or to use our internal resources to
commercialize Macrilen™ (macimorelin) in one or more of these countries. Our vision is to become a growth-oriented specialty biopharmaceutical company.

Macrilen™ (macimorelin)

Macrilen™ (macimorelin) is a novel orally available peptidomimetic ghrelin receptor agonist that stimulates the secretion of growth hormone by binding to
the ghrelin receptor (GHSR-1a) and that has potential uses in both endocrinology and oncology indications. Macrilen™ (macimorelin) was granted orphan-
drug designation by the FDA for use in evaluating growth hormone deficiency ("GHD").

Competitors  for  Macrilen™  (macimorelin)  as  a  product  for  the  evaluation  of  AGHD  are  principally  the  diagnostic  tests  currently  performed  by
endocrinologists, although none of these tests are approved by the FDA for this purpose. The most commonly used diagnostic tests for GHD are:

• Measurement of blood levels of Insulin Growth Factor ("IGF")-1, which is typically used as the first test when GHD is suspected. However, this test is

not used to definitively diagnose GHD because many growth hormone deficient patients show normal IGF-1 levels.

•

The Insulin Tolerance Test ("ITT"), which has historically been considered the gold standard for the evaluation of AGHD because of its high sensitivity
and specificity. However, the ITT is inconvenient to both patients and physicians, administered

24

intravenously (IV), and contra-indicated in certain patients, such as patients with coronary heart disease or seizure disorder, because it requires the patient
to  experience  hypoglycemia  to  obtain  a  result.  Some  physicians  will  not  induce  full  hypoglycemia,  intentionally  compromising  accuracy  to  increase
safety and comfort for the patient. Furthermore, administration of the ITT includes additional costs associated with the patient being closely monitored by
a physician for the two- to four-hour duration of the test and the test must be administered in a setting where emergency equipment is available and where
the patient may be quickly hospitalized. The ITT is not used for patients with co-morbidities, such as cardiovascular disease, seizure disorder or a history
of brain cancer or for patients who are elderly and frail, due to safety concerns.

•

•

The Glucagon Stimulation Test ("GST") is considered relatively safe by endocrinologists. The mechanism of action for this test is unclear. Also, this test
takes up to three to four hours. It produces side effects in up to one-third of the patients with the most common being nausea during and after the test.
This test is administered intramuscularly (IM).

The GHRH + ARG test (growth hormone releasing hormone-arginine stimulation) which is an easier test to perform in an office setting and has a good
safety profile but is considered to be costly to administer compared to the ITT and the GST. GHRH + ARG is approved in the EU and has been proposed
to be the best alternative to ITT, but GHRH is no longer available in the United States. This test is administered intravenously (IV).

Oral administration of Macrilen™ (macimorelin) offers convenience and simplicity over the current GHD tests used, all of which require either intravenous
or intramuscular administration. Additionally, Macrilen™ (macimorelin) may demonstrate a more favorable safety profile than existing diagnostic tests, some
of which may be inappropriate for certain patient populations, e.g. diabetes mellitus or coronary heart disease, and have demonstrated a variety of side effects,
which Macrilen™ (macimorelin) has not thus far. These factors may be limiting the use of GHD testing and may potentially enable Macrilen™ (macimorelin)
to become the product of choice in evaluating AGHD. We believe that Macrilen™ (macimorelin) is likely to rapidly displace the ITT as the preferred means
of evaluating AGHD for the following reasons:

•

it is safer and more convenient than the ITT because it does not require the patient to become hypoglycemic;

• Macrilen™ (macimorelin) is administered orally, while the ITT requires an intravenous injection of insulin;

• Macrilen™ (macimorelin) is a more robust test than the ITT leading to evaluable test results;

• Macrilen™ (macimorelin) results are highly reproducible;

•

•

the evaluation of AGHD using Macrilen™ (macimorelin) is less time-consuming and labor-intensive than the ITT; and

the evaluation can be conducted in the physician's office rather than in a hospital-like setting.

We believe that approximately 60,000 AGHD tests will be conducted annually, in the U.S, after the introduction of Macrilen™ (macimorelin). In addition,
based  on  published  information  from  the  U.S.  Centers  for  Disease  Control  and  Prevention,  different  scientific  publications  and  Navigant  Research,  we
estimate  that  the  total  potential  U.S.  market  for  AGHD  evaluation  is  approximately  150,000  tests  per  year,  including  the  evaluation  of  patients  who  have
suffered traumatic brain injury ("TBI"). In patients with TBI, GHD is frequent and may contribute to cognitive sequelae and reduction in quality of life. GHD
may develop in approximately 19% of both severe and moderate hospitalized TBI victims.

Development History

The following is a summary of the history of our development of Macrilen™ (macimorelin):

• We out-licensed the development compound macimorelin acetate to Ardana Bioscience in 2004. Ardana Bioscience subsequently initiated the clinical
development program of macimorelin acetate as an orally active compound intended to be used in the diagnosis of AGHD. Following agreement with the
FDA  on  the  study  design,  Ardana  Bioscience  initiated  a  pivotal  Phase  3  study  in  2007,  which  tested  the  compound  compared  to  a  test  of  growth
hormone-  releasing  hormone  ("GHRH")  +  L-Arginine  ("ARG"),  using  a  competitor's  compound.  The  study  was  discontinued  in  2008  due  to  Ardana
Bioscience's bankruptcy. We terminated Ardana Bioscience's license to the compound due to its bankruptcy.

•

On October 19, 2009, we announced that we had initiated activities intended to complete the clinical development of Macrilen™ (macimorelin) for use in
evaluating  AGHD.  We  had  already  assumed  the  sponsorship  of  the  Investigational  New  Drug  Application  ("IND")  from  Ardana  Bioscience  and
discussed  with  the  FDA  the  best  way  to  complete  the  ongoing  Phase  3  clinical  trial  and  subsequently  to  file  an  NDA  for  approval  of  Macrilen™
(macimorelin) for use in evaluating AGHD. The pivotal Phase 3 trial was designed to investigate the safety and efficacy of the oral administration of
Macrilen™ (macimorelin) as a growth hormone stimulator for use in evaluating AGHD. It was accepted by the FDA that for the ongoing part of the

25

study,  Macrilen™  (macimorelin)  would  not  be  compared  to  the  GHRH  +  ARG  test  because  the  competitor's  compound  had  been  removed  from  the
market.

On  December  20,  2010,  we  announced  we  had  reached  agreement  with  the  FDA  on  a  Special  Protocol  Assessment  ("SPA")  for  Macrilen™
(macimorelin), enabling us to complete the ongoing registration study required to gain approval for use in evaluating AGHD. The first part of the study,
conducted  by  our  former  licensee,  Ardana,  was  a  two-way  cross-over  study  and  included  43  patients  with  confirmed  AGHD  or  multiple  pituitary
hormone deficiencies and a low IGF-1. A control group of ten subjects without AGHD was matched to patients for age, gender, body mass index and (for
females) estrogen status.

On July 26, 2011, we announced the completion of the Phase 3 study of Macrilen™ (macimorelin) as a first oral product for use in evaluating AGHD and
the decision to meet with the FDA for the future filing of an NDA for the registration of Macrilen™ (macimorelin) in the United States.

On June 26, 2012, we announced that the final results from a Phase 3 trial for Macrilen™ (macimorelin) showed that the drug is safe and effective in
evaluating AGHD. Jose M. Garcia, MD, PhD, then of the Baylor College of Medicine and the Michael E. DeBakey VA Medical Center, disclosed these
data during an oral presentation at the 94th ENDO Annual Meeting and Expo in Houston, Texas. The study had originally been designed as a cross-over
trial of Macrilen™ (macimorelin) compared to the GHRH + ARG test in AGHD patients and in controls matched for body mass index ("BMI"), estrogen
status, gender and age. After 43 AGHD patients and ten controls had been tested, the GHRH + ARG test became unavailable because the competitor's
compound  was  withdrawn  from  the  market.  The  study  was  completed  by  testing  ten  more  AGHD  patients  and  38  controls  with  Macrilen™
(macimorelin) alone. Of the 53 AGHD subjects enrolled, 52 received Macrilen™ (macimorelin), and 50 who had confirmed AGHD prior to study entry
were included in this analysis, along with 48 controls. Two AGHD subjects could not be matched due to the combination of young age, high BMI and
estrogen use. The objective of this clinical trial was to determine the efficacy and safety of Macrilen™ (macimorelin) in the evaluation of AGHD. Mean
peak growth hormone ("GH") levels in AGHD patients and controls following Macrilen™ (macimorelin) administration were 2.36ng/mL (range 0.03-33)
and  17.71ng/mL  (range  10.5-94),  respectively.  The  ROC  plot  analysis  yielded  an  optimal  GH  cut-point  of  2.7ng/mL,  with  82%  sensitivity,  92%
specificity and a 13% misclassification rate. Obesity (BMI>30) was present in 58% of cases and controls, and peak GH levels were inversely associated
with  BMI  in  controls.  Adverse  events  ("AE")  were  seen  in  37%  of  AGHD  patients  and  in  21%  of  controls  following  Macrilen™  (macimorelin).  In
contrast, 61% of AGHD subjects and 30% of controls experienced AEs with L ARG+GHRH. The most common AEs after Macrilen™ (macimorelin)
were unpleasant taste (19.2%) and diarrhea (3.8%) for the AGHD patients and unpleasant taste (4.2%) and diarrhea (4.2%) for the matched controls. No
clinically meaningful changes from baseline in ECG results during the study for AGHD patients were observed; however, one control subject had an
ECG change (T wave abnormality and QTc interval prolongation) one hour after treatment with Macrilen™ (macimorelin) that was considered a serious
treatment-related  adverse  event  and  resolved  spontaneously  within  24  hours.  The  subject  had  been  pre-treated  with  citalopram,  a  drug  that  was  later
reported by the FDA to be associated with QT prolongation, although the patient had stopped this medication seven days prior to dosing. In an expert
statement  of  January  9,  2015,  Prof.  Dr.  W.  Haverkamp,  Centrum  Herz-,  Kreislauf-  und  Gefäßmedizin,  Charité,  Berlin,  considered  the  observed  QT
prolongation to be not related to Macrilen™ (macimorelin). Overall, this study demonstrated that Macrilen™ (macimorelin) is safe and effective for use
in evaluating AGHD.

In November 2013, we filed an NDA for Macrilen™ (macimorelin) for the evaluation of AGHD by evaluating the pituitary gland secretion of growth
hormone in response to an oral dose of the product. The FDA accepted the NDA for substantive review in January 2014. On November 6, 2014, the FDA
informed us, by issuing a Complete Response Letter ("CRL"), that it had determined that our NDA could not be approved in its then present form. The
CRL  stated  that  the  planned  analysis  of  our  pivotal  trial  did  not  meet  its  stated  primary  efficacy  objective  as  agreed  to  in  the  SPA.  The  CRL  further
mentioned issues related to the lack of complete and verifiable source data for determining whether patients were accurately diagnosed with AGHD. The
FDA concluded that, "in light of the failed primary analysis and data deficiencies noted, the clinical trial does not by itself support the indication." To
address the deficiencies identified above, the CRL stated that we needed to demonstrate the efficacy of Macrilen™ (macimorelin) as a diagnostic test for
GHD in a new, confirmatory clinical study. The CRL also stated that a serious event of electrocardiogram QT interval prolongation occurred for which
attribution to drug could not be excluded. Therefore, a dedicated thorough QT study to evaluate the effect of macimorelin on the QT interval would be
necessary.

Following receipt of the CRL, we assembled a panel of experts in the field of growth-hormone deficiency, including experts in the field from both the
United States and the EU. The panel met on January 8, 2015, during which we discussed our conclusions from the CRL, as well as the potential design of
a  new  pivotal  study.  The  panel  advised  us  to  continue  to  seek  approval  for  Macrilen™  (macimorelin)  because  of  their  confidence  in  its  efficacy  and
because there currently is no FDA-approved diagnostic test for AGHD. In parallel, we collected information on timelines and costs for such a study.

During an end-of-review meeting with the FDA on March 6, 2015, we agreed with the FDA on the general design of the confirmatory Phase 3 study of
Macrilen™  (macimorelin)  for  the  evaluation  of  AGHD,  as  well  as  evaluation  criteria.  We  agreed  with  the  FDA  that  the  confirmatory  study  will  be
conducted as a two-way crossover with the ITT as the benchmark comparator.

On April 13, 2015, we announced plans to conduct a new, confirmatory Phase 3 clinical study to demonstrate the efficacy of Macrilen™ (macimorelin)
for the evaluation of AGHD, as well as a dedicated thorough QT study to evaluate the effect of Macrilen™ (macimorelin) on myocardial repolarization.
The confirmatory Phase 3 clinical study of Macrilen™ (macimorelin), entitled "Confirmatory validation of oral macimorelin as a growth hormone (GH)
stimulation test (ST) for the diagnosis of AGHD in comparison with the insulin tolerance test (ITT)", was designed as a two-way crossover study with the
ITT  as  the  benchmark  comparator  and  involved  31  sites  in  the  United  States  and  Europe.  The  study  population  was  planned  to  include  at  least  110
subjects  (at  least  55  ITT-positive  and  55  ITT-negative)  with  a  medical  history  documenting  risk  factors  for  AGHD,  and  was  planned  to  include  a
spectrum of subjects from those with a low risk of having AGHD to those with a high risk of having the condition.

On May 26, 2015, we announced that we had received written scientific advice from the EMA regarding the further development plan, including the
study design, for the new confirmatory Phase 3 clinical study of Macrilen™ (macimorelin) for use in evaluating AGHD. As a result of the advice, we
believe that the confirmatory Phase 3 study that was agreed with the FDA meets the EMA's study-design expectations as well, allowing for U.S. and
European approval, if the study is successful.

On November 19, 2015, we announced the enrollment of the first patient in the confirmatory Phase 3 clinical study of Macrilen™ (macimorelin).

On  October  26,  2016,  we  announced  completion  of  patient  recruitment  for  the  confirmatory  Phase  3  clinical  trial  of  Macrilen™  (macimorelin)  as  a
growth hormone stimulation test for the evaluation of AGHD.

The dedicated thorough QT study to evaluate the effect of macimorelin on the QT interval, as requested by the FDA in the CRL, was conducted and
completed in 2016.

On January 4, 2017, we announced that, based on an analysis of top-line data, the confirmatory Phase 3 clinical trial of Macrilen™ (macimorelin) failed
to  achieve  one  of  its  co-primary  endpoints.  Under  the  study  protocol,  the  evaluation  of  AGHD  with  Macrilen™  (macimorelin)  would  be  considered
successful,  if  the  lower  bound  of  the  two-sided  95%  confidence  interval  for  the  primary  efficacy  variables  was  75%  or  higher  for  "percent  negative
agreement" with the ITT, and 70% or higher for the "percent positive agreement" with the ITT. While the estimated percent negative agreement met the
success criteria, the estimated percent positive agreement did not reach the criteria for a successful outcome. Therefore, the results did not meet the pre-
defined equivalence criteria which required success for both the percent negative agreement and the percent positive agreement.

On  February  13, 2017,  we  announced  that,  after  reviewing  the  raw  data  on  which  the  top-line  data  were  based,  we  had  concluded  that  Macrilen™
(macimorelin) had demonstrated performance supportive of achieving FDA registration and that we intended to pursue registration. The announcement
set forth the facts on which our conclusion was based. The Company met with the FDA at the end of March 2017 to discuss this position.

On  March  7,  2017,  we  announced  that  the  Pediatric  Committee  ("PDCO")  EMA  agreed  to  the  Company's  Pediatric  Investigation  Plan  ("PIP")  for
Macrilen™ (macimorelin) and agreed that the Company may defer conducting the PIP until after it files a Marketing Authorization Application ("MAA")
seeking marketing authorization for the use of Macrilen™ (macimorelin) for the evaluation of AGHD.

On July 18, 2017, we were provided a PDUFA date of December 30, 2017 by the FDA.

On November 27, 2017, the EMA accepted our MMA submission for Macrilen™ (macimorelin).

On  December  20,  2017,  the  FDA  approved  the  market  authorization  for  Macrilen™  (macimorelin),  to  be  used  in  the  diagnosis  of  patients  with  adult
growth hormone deficiency (AGHD).

On March 23, 2018, we received from the EMA a Day 120 List of Questions, which was issued in connection with our MMA submission for Macrilen™
(macimorelin). We are in the process of reviewing.

Zoptrex™

ZoptrexTM is a complex molecule that combines a synthetic peptide carrier with doxorubicin, a well-known chemotherapy agent. The synthetic peptide carrier
is a luteinizing hormone-releasing hormone ("LHRH") agonist, a modified natural hormone with

27

affinity  for  the  LHRH  receptor.  The  design  of  the  compound  allows  for  the  specific  binding  and  selective  uptake  of  the  cytotoxic  conjugate  by  LHRH
receptor-positive tumors.

On  January  30,  2017,  we  announced  the  completion  of  the  clinical  phase  of  the  pivotal  Phase  3  ZoptEC  (Zoptarelin  Doxorubicin  in  Endometrial  Cancer)
study with the occurrence of the 384th death.

On  May  1,  2017,  we  announced  that  the  ZoptEC  pivotal  Phase  3  clinical  study  of  Zoptrex™  (zoptarelin  doxorubicin)  in  women  with  locally  advanced,
recurrent or metastatic endometrial cancer did not achieve its primary endpoint of demonstrating a statistically significant increase in the median period of
overall survival of patients treated with Zoptrex™ (zoptarelin doxorubicin) as compared to patients treated with doxorubicin. The results of the study are not
supportive  to  pursue  regulatory  approval  by  the  FDA.  Based  on  this  outcome,  we  do  not  anticipate  conducting  clinical  trials  of  Zoptrex™  (zoptarelin
doxorubicin) with respect to any other indications. We also discontinued the development of AEZS-138/Disorazol Z, as it was based on the same concept as
Zoptrex™ (zoptarelin doxorubicin).

We have licensed the development, commercialization and certain other rights to Zoptrex™ to Sinopharm A-Think for China, Hong Kong and Macau; to an
affiliate of Orient EuroPharma Co., Ltd. for Taiwan and southeast Asia; to Rafa Laboratories, Ltd for Israel and the Palestinian territories and to Specialised
Therapeutics Asia Pte Ltd for Australia and New Zealand.

Overview of our Commercial Operations

Our commercial operations were significantly reduced in the fourth quarter of 2017. We eliminated our contract sales team in its entirety, as well as remaining
sales  management  in  November  2017,  in  accordance  with  the  terms  of  our  agreement  with  inVentiv  Commercial  Services,  LLC,  an  affiliate  of  inVentiv
Health, Inc. ("inVentiv"), a contract-sales organization. Our agreement with inVentiv commenced in November 2014.

Pursuant  to  termination  of  the  inVentiv  agreement,  we  ended  our  co-promotion  with  EMD  Serono,  Inc.  ("EMD  Serono")  and  Armune  BioScience,  Inc.
("Armune").

Until September 1, 2016, we co-promoted a product, EstroGel®, and until termination of our sales team in November 2017, the inVentiv sales force promoted
two products:

Saizen® [somatropin (rDNA origin) for injection] is a prescription medicine indicated for the treatment of growth hormone deficiency in children and adults.
We promoted Saizen® pursuant to our promotional services agreement (the “EMD Serono Agreement”) with EMD Serono Inc. (“EMD Serono”), which we
entered into in May 2015 and amended as of December 31, 2016. The EMD Serono Agreement, as amended, provided that we were to promote Saizen® in
specific agreed-upon U.S. territories to adult and pediatric endocrinologists in exchange for a sales commission that was based upon new patient starts of the
product. The agreement was terminated in accordance with its terms in December 2017.

APIFINY® is the only cancer-specific, non-PSA blood test for the evaluation of the risk of prostate cancer. The test was developed by Armune BioScience,
Inc. (“Armune”), a medical diagnostics company that develops and commercializes unique proprietary technology exclusively licensed from the University of
Michigan  for  diagnostic  and  prognostic  tests  for  cancer.  We  entered  into  a  co-marketing  agreement  with  Armune  in  November  2015  (the  “Armune
Agreement”), which was amended effective as of June 1, 2016, which allowed us to exclusively promote APIFINY® throughout the entire United States. We
received a commission for each test performed resulting from our targeted promotion without regard to any established baseline. The Armune Agreement, as
amended, had a three-year term that renewed automatically for successive one-year periods. The parties agreed in January 2018 that the Armune Agreement
was terminated.

On December 20, 2017, we received FDA approval for Macrilen™ (macimorelin) indicated for the diagnosis of AGHD. Following a detailed review process
undertaken  by  a  committee  of  our  independent  directors,  we  entered  into  the  Strongbridge  License  Agreement  to  carry  out  development,  manufacturing,
registration and commercialization of Macrilen™ (macimorelin) in the United States and Canada. We continue to explore various alternatives to monetizing
rights to macimorelin in other countries around the globe, including whether to find other license partners in these jurisdictions or to use its internal resources
to commercialize in certain of these countries.

Under the Strongbridge License Agreement, we received an upfront cash payment of $24,000,000, and, for as long as Macrilen™ (macimorelin) is patent-
protected, we will be entitled to a 15% royalty on net sales up to $75,000,000 and an 18% royalty on net sales above $75,000,000. Following the end of patent
protection in United States or Canada for Macrilen™ (macimorelin), we will be entitled to a 5% royalty on net sales in these countries. In addition, we also
will receive one-time payments from Strongbridge following the first achievement of the following commercial milestone events:

•

$4,000,000 on achieving $25,000,000 annual net sales

28

•

•

•

•

$10,000,000 on achieving $50,000,000 annual net sales

$20,000,000 on achieving $100,000,000 annual net sales

$40,000,000 on achieving $200,000,000 annual net sales

$100,000,000 on achieving $500,000,000 annual net sales

Upon  approval  by  the  FDA  of  a  pediatric  indication  for  Macrilen™  (macimorelin),  we  will  receive  a  one-time  milestone  payment  of  $5,000,000  from
Strongbridge.

Strongbridge will fund 70% of the costs of a worldwide pediatric development program to be run by the Company with customary oversight from a joint
steering  committee.  The  joint  steering  committee  will  be  comprised  of  four  persons,  two  of  whom  will  be  appointed  by  each  of  Strongbridge  and  the
Company.

A description of the principal geographic areas in which we compete, including a geographical and categorical breakdown of our revenues in the past three
years is presented in note 23 (Segment information) to our consolidated financial statements included in this Annual Report on Form 20-F at Item 18.

Seasonality

As a specialty biopharmaceutical company, the Company does not consider any of its products or services to be seasonal.

Raw Materials

Raw  materials  and  supplies  are  generally  available  in  quantities  adequate  to  meet  the  needs  of  our  business.  We  will  be  dependent  on  third-party
manufacturers for the pharmaceutical products that we will market. An interruption in the availability of certain raw materials or ingredients, or significant
increases in the prices paid by us for them, could have a material adverse effect on our business, financial condition, liquidity and operating results.

Regulation of Drug Development

Generally.  Governmental  authorities  in  the  United  States,  Canada,  Europe  and  other  countries  extensively  regulate  the  preclinical  and  clinical  testing,
manufacturing, labeling, storage, record keeping, advertising, promotion, export, marketing and distribution, among other things, of pharmaceuticals. Under
the laws of the United States, the countries of the EU, and other countries, we are subject to obligations to ensure that our clinical trials are conducted in
accordance with Good Clinical Practices ("GCP") guidelines and the investigational plan and protocols contained in an Investigational New Drug ("IND")
application, or comparable foreign regulatory submission. Set forth below is a brief summary of the material governmental regulations affecting us in the
major markets in which we intend to market our products and/or promote products that we acquire or in-license or to which we obtain promotional rights.

The United States. In the United States, the FDA's Center for Drug Evaluation and Research (CDER) under the Federal Food, Drug and Cosmetic Act of
1938,  as  amended  (the  "FDCA"),  the  Public  Health  Service  Act  and  other  federal  statutes  and  regulations,  subjects  pharmaceutical  products  to  rigorous
review. In order to market and sell a new drug product in the United States, we must first test it and send CDER evidence from these tests to prove that the
drug  is  safe  and  effective  for  its  intended  use.  In  most  cases,  these  tests  include  extensive  preclinical,  clinical,  and  laboratory  tests.  A  team  of  CDER
physicians, statisticians, chemists, pharmacologists, and other scientists reviews the company's data and proposed labeling. If this independent and unbiased
review establishes that a drug's health benefits outweigh its known risks, the drug is approved for sale. CDER does not test the drug itself but it does conduct
limited research in the areas of drug quality, safety, and effectiveness standards. Before approving a new drug or marketing application, the FDA may conduct
pre-approval inspections of the developer of the drug (the "sponsor"), its CROs and/or its clinical trial sites to ensure that clinical, safety, quality control, and
other  regulated  activities  are  compliant  with  GCP,  or  Good  Laboratory  Practices  ("GLP"),  for  specific  non-clinical  toxicology  studies.  Manufacturing
facilities used to produce a product are also subject to ongoing inspection by the FDA. The FDA may also require confirmatory trials, post-marketing testing,
and/or extra surveillance to monitor the effects of approved products, or place conditions on any approvals that could restrict the commercial applications of a
product.  Once  approved,  the  labeling,  advertising,  promotion,  marketing,  and  distribution  of  a  drug  or  biologic  product  must  be  in  compliance  with  FDA
regulatory requirements.

The first stage required for ultimate FDA approval of a new biologic or drug involves completion of preclinical studies whereby a sponsor must test new
drugs on animals for toxicity. Multiple  species  are  used  to  gather  basic  information  on  the  safety  and  efficacy  of  the  compound  being  investigated  and/or
researched. The FDA regulates preclinical studies under a series of regulations called the current GLP regulations as well as regulatory requirements found in
Part  21  subchapter  D  of  the  Code  of  Federal  Regulations.  If  the  sponsor  violates  these  regulations,  the  FDA  may  require  that  the  sponsor  replicate  those
studies or can subject

29

the sponsor to enforcement actions or penalties as described further below. The sponsor then submits to the FDA an IND application based on the results from
initial testing that include the drug's composition and manufacturing, along with a plan for testing the drug on humans. The FDA reviews the IND to ensure
that the proposed studies (clinical trials) do not place human subjects at unreasonable risk of harm. FDA also verifies that there are adequate informed consent
and human subject protections in place.

After a sponsor submits an IND application, it must wait 30 days before starting a clinical trial to allow FDA time to review the prospective study. If FDA
finds a problem, it can order a clinical hold to delay an investigation, or interrupt a clinical trial if problems occur during the study. After the IND application
is in effect, a sponsor may commence human clinical trials. The sponsor typically conducts human clinical trials in three sequential phases, but the phases
may overlap. In Phase 1 trials, the sponsor tests the product in a small number of patients or healthy volunteers (typically 20-80 healthy volunteers), primarily
for safety at one or more doses. The goal in this phase is to determine what the drug's most frequent side effects are and, often, how the drug is metabolized
and excreted. Phase 2 studies begin if Phase 1 studies do not reveal unacceptable toxicity. In Phase 2, in addition to safety, the sponsor evaluates the efficacy
of the product in a patient population somewhat larger than Phase 1 trials. The number of subjects in Phase 2 studies typically ranges from a few dozen to
about 300. This phase aims to obtain preliminary data on whether a drug works in people who have a certain disease or condition. At the end of Phase 2, the
FDA and sponsor try to come to an agreement on how large-scale studies in Phase 3 should be done.

Phase 3 studies begin if evidence of effectiveness is shown in Phase 2. Phase 3 trials typically involve additional testing for safety and clinical efficacy in an
expanded population at geographically dispersed test sites. The sponsor must submit to the FDA a clinical plan, or "protocol", accompanied by the approval
of the institutions participating in the trials, prior to commencement of each clinical trial. The FDA may order the temporary or permanent discontinuation of
a  clinical  trial  at  any  time.  In  the  case  of  product  candidates  for  cancer,  the  initial  human  testing  may  be  done  in  patients  with  the  disease  rather  than  in
healthy  volunteers.  Because  these  patients  are  already  afflicted  with  the  target  disease,  such  studies  may  provide  results  traditionally  obtained  in  Phase  2
studies. Accordingly, these studies are often referred to as "Phase 1/2" studies as they combine two phases. Even if patients participate in initial human testing
and a Phase 1/2 study is carried out, the sponsor is still responsible for obtaining all the data usually obtained in both Phase 1 and Phase 2 studies.

The  sponsor  must  submit  to  the  FDA  the  results  of  the  preclinical  and  clinical  testing,  together  with,  among  other  things,  detailed  information  on  the
manufacture and composition of the product, in the form of a New Drug Application ("NDA") or, in the case of a biologic, a Biologics License Applications
("BLA"). In a process that can take a year or more, the FDA reviews this application and, when and if it decides that adequate data are available to show that
the new compound is both safe and effective for a particular indication and that other applicable requirements have been met, approves the drug or biologic
for marketing. The amount of time taken for this approval process is a function of a number of variables, including the quality of the submission and studies
presented and the potential contribution that the compound will make in improving the treatment of the disease in question.

Orphan-drug  designation  is  granted  by  the  FDA  Office  of  Orphan  Drug  Products  to  novel  drugs  or  biologics  that  are  intended  for  the  safe  and  effective
treatment, diagnosis or prevention of rare diseases or disorders that affect fewer than 200,000 people in the U.S., or that affect more than 200,000 people but
are not expected to recover the costs of developing and marketing a treatment drug. The designation provides the sponsor with a seven-year period of U.S.
marketing  exclusivity  if  the  drug  is  the  first  of  its  type  approved  for  the  specified  indication  or  if  it  demonstrates  superior  safety,  efficacy  or  a  major
contribution to patient care versus another drug of its type previously granted the designation for the same indication. We have been granted orphan drug
designations for Macrilen™ (macimorelin) for the evaluation of growth hormone deficiency.

Under the Drug Price Competition and Patent Term Restoration Act of 1984 (the "Hatch-Waxman Act"), newly-approved drugs and indications may benefit
from a statutory period of non-patent data exclusivity. The Hatch-Waxman Act provides five-year data exclusivity to the first applicant to gain approval of an
NDA  for  a  new  chemical  entity,  or  NCE,  meaning  that  the  FDA  has  not  previously  approved  any  other  drug  containing  the  same  active  pharmaceutical
ingredient, or active moiety. Although protection under the Hatch-Waxman Act will not prevent the submission or approval of another full NDA, such an
NDA applicant would be required to conduct its own preclinical and adequate, well-controlled clinical trials to demonstrate safety and effectiveness.

The  Hatch-Waxman  Act  also  provides  three  years  of  data  exclusivity  for  the  approval  of  new  and  supplemental  NDAs,  including  Section  505(b)(2)
applications,  for,  among  other  things,  new  indications,  dosage  forms,  routes  of  administration,  or  strengths  of  an  existing  drug,  or  for  a  new  use,  if  new
clinical investigations that were conducted or sponsored by the sponsor are determined by the FDA to be essential to the approval of the application. This
exclusivity,  which  is  sometimes  referred  to  as  clinical  investigation  exclusivity,  would  not  prevent  the  approval  of  another  application  if  the  sponsor  has
conducted its own adequate, well-controlled clinical trials demonstrating safety and efficacy, nor would it prevent approval of a generic product that did not
incorporate the exclusivity-protected changes of the approved drug product.

30

The labeling, advertising, promotion, marketing, and distribution of a drug or biologic product must be in compliance with FDA regulatory requirements.
Failure to comply with applicable requirements can lead to the FDA demanding that production and shipment cease and, in some cases, that the manufacturer
recall products, or to enforcement actions that can include seizures, injunctions, and criminal prosecution. These failures can also lead to FDA withdrawal of
approval to market a product.

Canada. In Canada, the Therapeutic Products Directorate of Health Canada is the Canadian federal authority that regulates pharmaceutical drugs and medical
devices for human use. Prior to being given market authorization, a sponsor must present substantive scientific evidence of a product's safety, efficacy and
quality as required by the Food and Drugs Act and other legislation and regulations. The requirements for the development and sale of pharmaceutical drugs
in Canada are substantially similar to those in the United States, which are described above.

The European Union. Medicines can be authorized in the EU by using either the centralized authorization procedure or national authorization procedures. The
EU has implemented a centralized procedure coordinated by the EMA for the approval of human medicines, which results in a single marketing authorization
issued by the European Commission that is valid across the EU, as well as Iceland, Liechtenstein and Norway. The centralized procedure is compulsory for
human medicines that are derived from biotechnology processes, such as genetic engineering, that contain a new active substance indicated for the treatment
of certain diseases, such as HIV/AIDS, cancer, diabetes, neurodegenerative disorders or autoimmune diseases and other immune dysfunctions, and designated
orphan medicines. For medicines that do not fall within these categories, an applicant has the option of submitting an application for a centralized marketing
authorization to the EMA, as long as the medicine concerned is a significant therapeutic, scientific or technical innovation, or if its authorization would be in
the interest of public health.

There are also two other possible routes to authorize medicinal products in several EU countries, which are available for investigational drug products that fall
outside the scope of the centralized procedure:

• Decentralized  procedure.  Using  the  decentralized  procedure,  a  sponsor  may  apply  for  simultaneous  authorization  in  more  than  one  EU  country  of
medicinal products that have not yet been authorized in any EU country and that do not fall within the mandatory scope of the centralized procedure. The
application will be reviewed by a selected Reference Member State ("RMS"). The Marketing Authorization granted by the RMS will then be recognized by
the other Member States involved in this procedure.

• Mutual  recognition  procedure.  In  the  mutual  recognition  procedure,  a  medicine  is  first  authorized  in  one  EU  Member  State,  in  accordance  with  the
national  procedures  of  that  country.  Following  this,  further  marketing  authorizations  can  be  sought  from  other  EU  countries  in  a  procedure  whereby  the
countries concerned agree to recognize the validity of the original, national marketing authorization.

Regulation of Commercial Operations

The  marketing,  promotional,  and  pricing  practices  of  human  pharmaceutical  manufacturers,  as  well  as  the  manner  in  which  manufacturers  interact  with
purchasers and prescribers, are subject to various U.S. federal and state laws, including the federal anti-kickback statute and the False Claims Act and state
laws governing kickbacks, false claims, unfair trade practices, and consumer protection, and to similar laws in other countries. In the U.S., these laws are
administered by, among others, the Department of Justice ("DOJ"), the Office of Inspector General of the Department of Health and Human Services, the
Federal Trade Commission, the Office of Personnel Management, and state attorneys general. Over the past several years, the FDA, the DOJ, and many other
agencies have increased their enforcement activities with respect to pharmaceutical companies and increased the inter-agency coordination of enforcement
activities.

In  the  U.  S.,  biopharmaceutical  and  medical  device  manufacturers  are  required  to  record  any  transfers  of  value  made  to  licensed  physicians  and  teaching
hospitals and to disclose such data to the Department of Health and Human Services ("HHS"). In addition to civil penalties for failure to report transfers of
value to physicians or teaching hospitals, there will be criminal penalties if a manufacturer intentionally makes false statements or excludes information in
such reports. The payment data across biopharmaceutical and medical device companies is posted by HHS on a publicly available website. Increased access
to such data by fraud and abuse investigators, industry critics and media will draw attention to our collaborations with reported entities and will importantly
provide  opportunities  to  underscore  the  critical  nature  of  our  collaborations  for  developing  new  medicines  and  exchanging  scientific  information.  This
national payment transparency effort coupled with industry commitment to uphold voluntary codes of conduct (such as the PhRMA Code on Interactions with
Healthcare Professionals and PhRMA Guiding Principles Direct to Consumer Advertisements About Prescription Medicines) and rigorous internal training
and compliance efforts will complement existing laws and regulations to help ensure ethical collaboration and truthful product communications.

The Canadian association of Research-Based Pharmaceutical Companies ("Rx & D") has adopted "Guidelines for Transparency in Stakeholder Funding" that
require member companies to regularly disclose, by means of the web sites and annual reports, a list of all stakeholders to which they provide direct funding.
The term "stakeholder" is defined in Rx & D's Code of Ethical Practices to include "Health Care Professionals". In the EU, the disclosure code of transfers of
value to healthcare professionals

31

and organizations adopted by the European Federation of Pharmaceutical Industries and Associations ("EFPIA") requires all members of EFPIA to disclose
transfers of value to healthcare professionals and healthcare organizations beginning in 2016, covering the relevant transfers in 2015. Each member company
will be required to document and disclose: (i) the names of healthcare professionals and associations that have received payments or other transfers of value
and (ii) the amounts or value transferred, and the type of relationship.

For more information about the regulatory risks associated with our business operations, see "Item 3D. Risk Factors".

Intellectual Property - Patents

We seek to protect our compounds, manufacturing processes, compositions and methods of medical use for our lead drugs and drug candidates through a
combination of patents, trade secrets and know-how. Our patent portfolio consists of approximately 12 owned and in-licensed patent families (issued, granted
or pending in the United States, Europe and other jurisdictions). The patent positions of companies in the biotechnology and pharmaceutical industries are
highly uncertain and involve complex legal and factual questions. Therefore, we cannot predict the breadth of claims, if any, that may be allowed under any of
our  patent  applications,  or  the  enforceability  of  any  of  our  allowed  patents.  See  "Item  3.D.  Risk  Factors  -  We  may  not  obtain  adequate  protection  for  our
products through our intellectual property."

Patents extend for varying periods according to the date of patent filing or grant and the legal term of patents in the various countries where patent protection
is obtained. The actual protection afforded by a patent, which can vary from country to country, depends on the type of patent, the scope of its coverage and
the availability of legal remedies in the country. In the United States, the patent term of a patent that covers an FDA-approved drug may also be eligible for
patent term extension, which permits patent term restoration as compensation for the patent term lost during the FDA regulatory review process. The Hatch-
Waxman Act permits a patent term extension of up to five years beyond the expiration of the patent, in which the patentee may file an application for yearly
interim extensions within five years if the patent will expire and the FDA has not yet approved the NDA. The length of the patent term extension is related to
the length of time the drug is under regulatory review. Patent extension cannot extend the remaining term of a patent beyond a total of 14 years from the date
of product approval and only one patent applicable to an approved drug may be extended.

Similar provisions are available in Europe and other foreign jurisdictions to extend the term of a patent that covers an approved drug. In these jurisdictions,
however, no interim extensions exist and the marketing approval must be granted before the patent expires. In the future, if and when our pharmaceutical
products  receive  FDA  approval,  we  expect  to  apply  for  patent  term  extensions  on  patents  covering  those  products.  While  we  anticipate  that  any  such
applications for patent term extensions will likely be granted, we cannot predict the precise length of time for which such patent terms would be extended in
the United States, Europe or other jurisdictions. If we are not able to secure patent term extensions on patents covering our products for meaningful periods of
additional time, we may not achieve or sustain profitability, which would adversely affect our business.

In addition to patent protection, our products may benefit from the market-exclusivity provisions contained in the orphan-drug regulations or the pediatric-
exclusivity provisions or other provisions of the FDA Act, such as new chemical entity exclusivity or new formulation exclusivity. Orphan drug regulations
provide incentives to pharmaceutical and biotechnology companies to develop and manufacture drugs for the treatment of rare diseases, currently defined as
diseases that exist in fewer than 200,000 individuals in the U.S., or diseases that affect more than 200,000 individuals in the U.S. but that the sponsor does not
realistically anticipate will generate a net profit. Under these provisions, a manufacturer of a designated orphan drug can seek tax benefits, and the holder of
the first FDA approval of a designated orphan product will be granted a seven-year period of marketing exclusivity for such FDA-approved orphan product.
In  the  U.S.,  the  FDA  has  the  authority  to  grant  additional  data  protection  for  approved  drugs  where  the  sponsor  conducts  specified  testing  in  pediatric  or
adolescent populations. If granted, this pediatric exclusivity provides an additional six months which are added to the term of data protection as well as to the
term of any relevant patents, to the extent these protections have not already expired. We may also seek to utilize market exclusivities in other territories, such
as in the EU. There can be no assurance that any of our drug candidates will obtain such orphan drug designation, pediatric exclusivity, new chemical entity
exclusivity or any other market exclusivity in the U.S., the EU or any other territory, or that we will be the first to receive the regulatory approval in a given
country or territory for such drugs so as to be eligible for any market exclusivity protection.

Zoptrex™

We  have  licensed  the  intellectual  property  and  associated  rights  relating  to  LHRH  agonists  and  LH-RH  antagonists  carrying  various  cytotoxic  radicals
(including zoptarelin doxorubicin) from the Administrators of the Tulane Educational Fund ("Tulane") pursuant to a license agreement dated September 17,
2002  between  Tulane,  as  licensor,  and  AEZS  GmbH,  as  licensee  (the  "Tulane  Agreement").  The  Tulane  Agreement  grants  to  us  an  exclusive  worldwide
license for all therapeutic uses of LH-RH agonists and LH-RH antagonists carrying various cytotoxic radicals, to the extent covered by one of the patents
listed below. The term of the Tulane Agreement continues for ten years after the first commercial sale of a product based on the licensed intellectual property

32

(a "Licensed Product") or until the expiration of the last to expire of the patents listed below, whichever is longer, on a country-by- country basis.

Pursuant  to  the  Tulane  Agreement,  we  are  required  to  pay  Tulane  the  following  amounts:  (i)  $400,000  upon  the  first  grant  of  regulatory  approval  for  a
Licensed Product in the U.S., Canada, the EU or Japan; (ii) 10% of all consideration received by us from a sublicensee for authorization to use the licensed
intellectual property to develop, manufacture, market, distribute and sell a Licensed Product; (iii) 2.5% of our net sales of Licensed Products; and (iv) 50% of
any  royalties  that  we  receive  from  a  sublicensee  with  respect  to  its  net  sales  of  Licensed  Products;  provided,  however,  that  the  payment  with  respect  to
royalties received from a sublicensee shall not be less than 1.75% nor more than 2.5% of the sublicensee's net sales of the Licensed Product.

The following patents are covered by the Tulane Agreement:

comprising the compounds as well as their medical use for the treatment of tumors. This patent expired in November 2016.

In early 2015, we filed a European patent application directed to a novel method of manufacturing Zoptrex™. Within the 12 months priority period, we also
filed an international patent application for the manufacturing process, as well as national patent applications in selected countries, including the U.S., China,
and Taiwan, Japan and India. We decided to file patent applications in additional territories after the European Patent Office issued a search report for the
European patent application that we consider to be favorable. The claimed manufacturing process is expected to result in a significant reduction in our cost of
manufacturing Zoptrex™, providing us with what should be a stronger competitive position and discouraging competition from generic manufacturers after
our five-year period of data exclusivity expires.

Operating and Financial Review and Prospects

Key Developments

Macrilen™ (macimorelin), a ghrelin receptor agonist, is a novel orally-active small molecule that stimulates the secretion of growth hormone. Macrilen™
(macimorelin) has been granted orphan drug designation by the FDA for the evaluation of growth hormone deficiency. We own the worldwide rights to this
novel patented compound. Macrilen™ (macimorelin) is our proposed trade name for macimorelin. The proposed trade name was conditionally approved by
the FDA. On December 16, 2016, we were advised by the EMA that Macrilen™ was rejected as the proposed invented name for macimorelin because of its
similarity to the names of other medicines. On March 8, 2018, we applied for two new invented names for macimorelin: Macrilen ST and Macrilen GHST;
however, we are also evaluating alternative names given recent feedback received from the EMA.

In  late  2016,  we  concluded  a  confirmatory  Phase  3  clinical  trial  of  Macrilen™  (macimorelin)  for  the  evaluation  of  growth  hormone  deficiency  in  adults
AGHD.  The  confirmatory  trial  was  an  open-label,  randomized,  two-way  crossover  study  that  compared  the  results  of  the  evaluation  of  AGHD  using
Macrilen™ (macimorelin) to the results of the evaluation of AGHD using a procedure known as the "Insulin Tolerance Test" (the "ITT") on the same patients.
The trial involved patients, each of whom was evaluated for AGHD using both Macrilen™(macimorelin) and the ITT. Thirty of the patients were evaluated
using Macrilen™(macimorelin) a second time to measure the repeatability of the result obtained using Macrilen™ (macimorelin) as the evaluation method.
The study population consisted of more than 110 patients who were suspected of having AGHD as a result of the presence of one or more symptoms. This
segment  of  the  population  included  a  range  of  patients  from  those  considered  at  low  risk  of  having  AGHD  to  those  considered  at  high  risk.  The  study
population also included 25 healthy subjects, who had no risk of having AGHD.

On  January  4,  2017,  we  announced  that  the  confirmatory  Phase  3  clinical  trial  of  Macrilen™(macimorelin)  failed  to  achieve  its  objective  of  validating  a
single oral dose of Macrilen™ (macimorelin) for the evaluation of AGHD, using the ITT as a comparator. Based on an analysis of top-line data, Macrilen™
(macimorelin) did not achieve equivalence to the ITT as a means of diagnosing AGHD. Under the study protocol, the evaluation of AGHD with Macrilen™
(macimorelin) would have been considered successful if the lower bound of the two-sided 95% confidence interval for the primary efficacy variables was
75%  or  higher  for  "percent  negative  agreement"  with  the  ITT,  and  70%  or  higher  for  the  "percent  positive  agreement"  with  the  ITT.  While  the  estimated
percent negative agreement met the success criteria, the estimated percent positive agreement did not reach the criteria for a successful outcome. Therefore,
the  results  did  not  meet  the  pre-defined  equivalence  criteria  which  required  success  for  both  the  percent  negative  agreement  and  the  percent  positive
agreement.

On  February  13,  2017,  we  announced  that,  following  a  comprehensive  review  of  the  data  obtained  from  the  confirmatory  Phase  3  clinical  trial  of
Macrilen™(macimorelin) for the evaluation of AGHD using the ITT as a comparator, we concluded that Macrilen™(macimorelin) demonstrated performance
supportive of FDA registration consideration.

35

 
 
 
 
 
 
 
 
 
On March 7, 2017, we announced that the Pediatric Committee of the EMA agreed to our Pediatric Investigation Plan ("PIP") for Macrilen™ (macimorelin)
and agreed that we may defer conducting the PIP until after we file an MAA seeking marketing authorization for the use of Macrilen™ (macimorelin) for the
evaluation of AGHD.

On  March  30,  2017,  we  announced  that,  following  our  meeting  with  the  FDA  on  March  29,  2017,  we  intended  to  file  an  NDA  seeking  approval  of
MacrilenTM (macimorelin) for the evaluation of AGHD. The announcement also indicated that during our meeting with the FDA, the FDA stated that the
clinical studies performed with respect to MacrilenTM (macimorelin) address the prior deficiencies mentioned in the November 5, 2014 complete response
letter  and  that  this  conclusion  paved  the  way  for  re-submission  by  us  of  an  NDA  for  MacrilenTM  (macimorelin).  While  indicating  that  the  conclusions
regarding the performance of MacrilenTM  (macimorelin)  are  review  issues  subject  to  an  examination  of  the  complete  data  set,  the  FDA  indicated  that  the
summary data submitted by us prior to the meeting appear to support the propositions advanced by us. Most importantly, the FDA specified the additional
statistical analysis of existing data that would be required to further support our conclusions.

On June 30, 2017, we announced that we had resubmitted an NDA to the FDA seeking approval of MacrilenTM (macimorelin).

On July 18, 2017, we announced that we had been notified by the FDA that our NDA seeking approval of MacrilenTM (macimorelin) for the evaluation of
AGHD had been accepted as a complete response to the FDA's November 5, 2014 complete response letter and granted a PDUFA date of December 30, 2017.

On November 27, 2017, we announced that the MAA for the use of MacrilenTM (macimorelin) for the evaluation of AGHD has been accepted by the EMA
for regulatory review. The start of the EMA review procedure for the MAA has been confirmed by EMA as November 23, 2017.

On December 20, 2017, we announced that the FDA granted marketing approval for MacrilenTM (macimorelin) to be used in the diagnosis of patients with
AGHD. On January 17, 2018, we announced that through AEZS Germany, we entered into the Strongbridge License Agreement to carry out development,
manufacturing, registration and commercialization of Macrilen™ (macimorelin) in the United States and Canada. We continue to explore various alternatives
to monetize our rights to Macimorelin in other countries around the globe.

Outsourcing and Out-Licensing Non-Strategic Activities/Assets

Zoptrex™

On  May  1,  2017,  we  announced  that  the  ZoptEC  pivotal  Phase  3  clinical  study  of  Zoptrex™  (zoptarelin  doxorubicin)  in  women  with  locally  advanced,
recurrent or metastatic endometrial cancer did not achieve its primary endpoint of demonstrating a statistically significant increase in the median period of
overall survival of patients treated with Zoptrex™ (zoptarelin doxorubicin) as compared to patients treated with doxorubicin. The results of the study are not
supportive  to  pursue  regulatory  approval  by  the  FDA.  Based  on  this  outcome,  we  do  not  anticipate  conducting  clinical  trials  of  Zoptrex™  (zoptarelin
doxorubicin) with respect to any other indications. We also discontinued the development of AEZS-138/Disorazol Z, as it was based on the same concept as
Zoptrex™ (zoptarelin doxorubicin).

Commercial Operations

Our commercial operations were significantly reduced in the fourth quarter of 2017. We eliminated our contract sales team in its entirety, as well as remaining
sales  management  in  November  2017,  in  accordance  with  the  terms  of  our  agreement  with  inVentiv  Commercial  Services,  LLC,  an  affiliate  of  inVentiv
Health, Inc. ("inVentiv"), a contract-sales organization.

Pursuant to termination of the inVentiv agreement, we ended our co-promotion with EMD Serono, Inc. and Armune BioScience, Inc.

Until termination of our sales team in November 2017, the inVentiv sales force promoted two products during 2017:

Saizen® [somatropin (rDNA origin) for injection] is a prescription medicine indicated for the treatment of growth hormone deficiency in children and adults.
We promoted Saizen® pursuant to our promotional services agreement (the "EMD Serono Agreement") with EMD Serono, which we entered into in May
2015 and amended as of December 31, 2016. The EMD Serono Agreement, as amended, provided that we were to promote Saizen® in specific agreed-upon
U.S.  territories  to  adult  and  pediatric  endocrinologists  in  exchange  for  a  sales  commission  that  was  based  upon  new  patient  starts  of  the  product.  The
agreement was terminated in accordance with its terms on December, 13 2017.

APIFINY® is the only cancer-specific, non-PSA blood test for the evaluation of the risk of prostate cancer. The test was developed by Armune BioScience,
Inc. ("Armune"), a medical diagnostics company that develops and commercializes unique proprietary technology exclusively licensed from the University of
Michigan  for  diagnostic  and  prognostic  tests  for  cancer.  We  entered  into  a  co-marketing  agreement  with  Armune  in  November  2015  (the  "Armune
Agreement"), which was amended effective as of June 1, 2016, which allowed us to exclusively promote APIFINY® throughout the entire United States. We
received a commission for each test performed resulting from our targeted promotion without regard to any established baseline. The Armune Agreement, as
amended, had a three-year term that renewed automatically for successive one-year periods. The parties agreed in January 2018 that the Armune Agreement
was terminated.

Effective on November 3, 2017, we terminated the employment of Jude Dinges, our Senior Vice President and Chief Commercial Officer.

Corporate Activities

In July 2017, our subsidiary located in Germany and its Works Council approved a restructuring program (the "2017 German Restructuring"), which was
rolled out as a consequence of the negative Phase 3 clinical trial results of Zoptrex™ (zoptarelin doxorubicin) announced on May 1, 2017 and the related
impact  on  our  product  pipeline.  This  was  also  part  of  the  continued  strategy  to  transition  the  Company  into  a  commercially  operating  specialty
biopharmaceutical  organization  focused  on  the  development  and  commercialization  of  Macrilen™  (macimorelin),  including  through  out-licensing
arrangements and pursuing in-licensing opportunities. The goal of the 2017 German Restructuring is to reduce to a minimum our research and development
("R&D") activities and is expected to result in the termination of approximately 24 employees of the German subsidiary.

The  Company  started  implementing  the  2017  German  Restructuring  in  the  fourth  quarter  of  2017,  with  staff  departures  expected  to  be  completed  over  a
period  of  approximately  18  months.  Total  initial  restructuring  costs  associated  with  the  2017  German  Restructuring  include  severance  accruals  and  other
directly  related  costs  ($2,002,000)  and  an  onerous  lease  provision  ($1,113,000),  which  has  been  recorded  as  follows  in  the  accompanying  consolidated
statement of comprehensive loss: $2,644,000 in R&D costs, $275,000 in General and administrative ("G&A") expenses and $196,000 in selling expenses.
These estimated costs may vary as a result of changes in the underlying assumptions applied thereto, including but not limited to, the time needed to sublease
the unused premises. Most of the restructuring accruals are expected to be paid in the financial year ending December 31, 2018.

CEO Appointment and CFO Resignation and Appointment

On July 20, 2017, the board of directors of the Company (the "Board") announced the appointment of Michael Ward as the Company's President and Chief
Executive Officer ("CEO"). Further, on September 25, 2017, the Company announced the appointment of Jeffrey Whitnell to the position of Interim Chief
Financial Officer ("CFO"). Mr. Whitnell resigned as CFO effective December 7, 2017.

On March 5, 2018, the Company appointed James Clavijo as the Chief Financial Officer, effective that date.

Strategic Review Committee

On July 20, 2017, the Company announced that the Board had established a special committee of independent directors (the "Strategic Review Committee")
to develop, consider, investigate and exercise oversight relating to potential strategic alternatives to maximize potential future growth and stakeholder value of
the  Company,  including  continuing  to  execute  on  our  existing  business  plan  and/or  considering  and  recommending  changes  to  our  management  and
governance.

On August 8, 2017, we announced that the Strategic Review Committee engaged a consulting firm and a financial advisor to assist in its efforts. The Strategic
Review Committee retained Stifel, Nicolaus & Company as advisor in part to validate the commercial potential of Macrilen™(macimorelin) to assist it in
determining the best means of maximizing value, which included evaluating and recommending modes of distribution including entering into partnerships or
building an internal sales force, raising capital including through an investment from a strategic partner, or selling some or all of the Company and its assets.
On January 16, 2018, through AEZS Germany, the Company entered into the Strongbridge License Agreement.

In January 2018, in accordance with the written mandate of the Strategic Review Committee, the members of the Strategic Review Committee determined
that  the  responsibilities  of  the  Strategic  Review  Committee  had  been  performed  and  were  at  an  end  and  the  Strategic  Review  Committee  was  dissolved
effective as of January 22, 2018.

Contingencies

In late July 2017, we terminated for cause the employment of Mr. David A. Dodd, the former President and Chief Executive Officer of the Company and the
employment  of  Mr.  Philip  A.  Theodore,  the  former  Senior  Vice  President,  Chief  Administrative  Officer,  General  Counsel  and  Corporate  Secretary  of  the
Company. All outstanding stock options held by both former officers were cancelled effective as of their respective termination dates, in accordance with the
provisions of our Stock Option Plan (as defined below).

On August 3, 2017, we announced that we had filed a lawsuit against both Messrs. Dodd and Theodore for damages suffered by us for breach of confidence
and/or breach of fiduciary duty in an amount to be determined prior to trial. We are also seeking, among other things, an injunction to prevent both Messrs.
Dodd and Theodore from (i) continuing to use our confidential and proprietary information without authorization; and (ii) mounting a proxy contest that will
be premised upon the breaches of fiduciary and statutory duties and breaches of confidence alleged in the lawsuit. We engaged external counsel to conduct an
internal investigation related to this lawsuit, which is still ongoing.

On December 21, 2017, Messrs. Dodd and Theodore brought a counterclaim against the Company and its Chair, Carolyn Egbert, in the amount of CAN$6.0
million alleging, among other things, that defamatory statements were made against Messrs. Dodd and

38

Theodore.  The  Company  and  its  Chair  consider  the  counterclaim  against  them  to  be  entirely  without  merit,  and  intend  to  vigorously  defend  against  the
counterclaim.

In August 2017, Mr. Dodd filed a lawsuit in the Court of Common Pleas of South Carolina against us for damages of approximately U.S.$1.7 million. He is
also requesting that all of his outstanding stock options vest effective upon his termination date. We cannot predict at this time the final outcome or potential
losses, if any, with respect to this lawsuit. On September 5, 2017, the lawsuit in the Court of Common Pleas of South Carolina was moved to the Federal
Court in South Carolina.

Cogas Consulting, LLC ("Cogas") filed a lawsuit against the Company in state court in Fulton County, Georgia on February 2, 2018. Cogas alleges that its
employee (and sole shareholder) John Sharkey is entitled to a "success fee" commission on the Strongbridge License Agreement. Cogas is claiming damages
in the form of a lost commission on the transaction. Cogas claims its commission is 5% on payments the Company receives within the first three years after
January 14, 2018. Cogas alleges it is entitled to 5% of the $24 million Strongbridge already paid the Company, plus 5% of any royalty Strongbridge pays the
Company through January 17, 2021. The Company plans to vigorously defend this matter.

2017 compared to 2016

Revenues

Sales commission and other were $0.1 million and $0.5 million for the three and twelve months ended December 31, 2017 and $0.1 million and $0.4 million
for the same periods in 2016, and thus increased in 2017 as compared to 2016. In 2017, those revenues mainly resulted from our sales team exceeding pre-
established  unit  sales  baseline  thresholds  under  our  co-promotion  agreement  to  sell  Saizen®.  We  also  generated  sales  commission  in  connection  with  our
promotion of APIFINY®. In the corresponding periods in 2016, sales commission and other revenues were mainly related to EstroGel®.

License fees were $0.1 million and $0.5 million for the three and twelve months ended December 31, 2017, as compared to $0.2 million and $0.5 million for
the same periods in 2016.

The  Company  currently  has  deferred  revenues  at  December  31,  2017  of  $541,000  relating  to  non-refundable  upfront  payments  it  previously  received  for
licensing  and  technology  transfer  arrangements  that  it  entered  into  with  respect  to  the  development  of  Zoptrex™  in  various  territories.  Due  to  events  that
occurred in 2018, the Company does not anticipate development of Zoptrex™ under the licensing agreements, therefore the Company's remaining carrying
amount of deferred revenues will be recognized in the first quarter of 2018 as income.

Operating Expenses

R&D costs were $0.5 million and $10.7 million for the three and twelve months ended December 31, 2017, compared to $4.6 million and $16.5 million for
the same periods in 2016. R&D costs decreased for the three-month and twelve-month periods ended December 31, 2017 as compared to the same period in
2016. The decrease in R&D costs is mainly attributable to lower comparative third-party costs, as described below, partially offset by the recording, in the
third quarter of 2017, of a provision in connection with the 2017 German Restructuring.

Additionally, the decrease in our R&D costs for the twelve months ended December 31, 2017, as compared to the same period in 2016, is attributable to lower
employee compensation and benefits costs, lower facilities rent and maintenance costs as well as lower other costs. A substantial portion of this decrease is
due to the realization of cost savings in connection with our ongoing efforts to streamline our R&D activities and to increase our commercial operations and
flexibility by reducing our R&D staff, which was started in 2014 (the "Resource Optimization Program"). The R&D costs for the year ended December 31,
2017 were lower than anticipated mainly because we were able to negotiate reductions to a change order received from our principal R&D third-party service
provider.

As shown above, a substantial portion of the R&D costs relates to development initiatives associated with Zoptrex™, and with our pivotal Phase 3 ZoptEC
clinical trial initiated in 2013 with Ergomed. Third-party costs attributable to Zoptrex™ decreased considerably during the twelve months ended December
31, 2017, as compared to the same period in 2016, mainly since we completed the clinical portion of the ZoptEC trial during the first quarter of 2017 which
was partially offset by the additional liability recognized following the negative ZoptrexTM top-line results.

Third-party costs attributable to Zoptrex™ decreased during the three and twelve months ended December 31, 2017, as compared to the same period in 2016,
mainly  since  we  closed  out  the  study  and  related  activities  in  the  second  quarter  following  the  negative  ZoptrexTM  top-line  results  on  May  1,  2017.  The
negative costs for the three-month period ended December 31, 2017 are mainly explained by lower close out costs as compared to the accrual made in the
second quarter.

Third-party costs attributable to Macrilen™ (macimorelin) decreased during the three and twelve months ended December 31, 2017, as compared to the same
period in 2016. This is mainly since we completed the Phase 3 clinical trial at the end of 2016. The costs incurred in 2017 related to the detailed analysis of
the top-line results as well as the preparation of the NDA filing which was submitted on June 30, 2017. The costs reversal in the fourth quarter of 2017 are
explained mainly by the reductions to close out costs.

Excluding the impact of foreign exchange rate fluctuations, we expect that we will incur overall R&D costs of between $1.0 million and $2.0 million for the
year ended December 31, 2018.

G&A expenses were $2.8 million and $8.2 million for both the three and twelve-month periods ended December 31, 2017, as compared to $1.8 million and
$7.1 million for the same periods in 2016. The increase in our G&A costs for the three and twelve months ended December 31, 2017, as compared to the
same period in 2016, is mainly due to outside legal costs. The G&A expenses are in line with expectations.

Excluding the impact of foreign exchange rate fluctuations and the recording of transaction costs related to potential financing activities (not currently known
or estimable), we expect that G&A expenses will range between $9.0 million and $11.0 million in 2018.

Selling expenses were $0.5 million and $5.1 million for the three and twelve months ended December 31, 2017, as compared to $1.5 million and $6.7 million
for the same periods in 2016. Selling expenses for the three and twelve months ended December 31, 2017 and 2016 represent mainly the costs of our sales
force related to the co-promotion activities as well as our sales management team. The decrease in selling expenses is explained by the elimination of sales
representatives. In the fourth quarter, we eliminated all sales representatives as part of the restructuring efforts. Based on currently available information, we
expect selling expenses to range between $0.2 million and $0.5 million in 2018.

Net finance income (costs) was $(0.4) million and $2.8 million for the three and twelve months ended December 31, 2017, as compared to $(0.6) million and
$4.5 million, for the same periods in 2016. The decrease in finance income is mainly attributable to the change in fair value of warrant liability. Such change
in  fair  value  results  from  the  periodic  "mark-to-market"  revaluation,  via  the  application  of  pricing  models,  of  outstanding  share  purchase  warrants.  The
closing price of our common shares, which, on the NASDAQ, fluctuated from $0.84 to $3.65 during the twelve-month period ended December  31,  2017,
compared to $2.67 to $4.94 during the same period in 2016, also had a direct impact on the change in fair value of warrant liability.

Net loss for the three and twelve months ended December 31, 2017 was $0.5 million and $16.8 million (or $0.03 and $1.12 per share), as compared to a net
loss of $8.2 million and $25.0 million (or $0.71 and $2.41 per share) for the same periods in 2016. The decrease in net loss for the three-month period ended
December  31,  2017  is  a  result  of  the  reduction  in  third  party  R&D  costs.  The  reduction  is  attributed  to  closing  out  the  Zoptrex  study  and  successful
completion in the U.S. of the Macrilen™ (macimorelin) filing.

2016 compared to 2015

Revenues

Revenues were $0.9 million for the year ended December 31, 2016 compared to $0.5 million for the same period in 2015. In 2016, the sales commission and
other revenue mainly resulted from our sales team exceeding pre-established unit sales baseline thresholds under our co-promotion agreement to sell Saizen®.
We  also  generated  sales  commission  in  connection  with  our  promotion  of  APIFINY®.  In  the  corresponding  periods  in  2015,  sales  commission  and  other
revenues  were  mainly  related  to  EstroGel®.  The  increase  in  licensing  fees  is  explained  by  the  out-licensing  agreements  that  we  entered  into  in  2016  for
ZoptrexTM.

Operating Expenses

R&D costs were $16.5 million for the year ended December 31, 2016 compared to $17.2 million for the same period in 2015.

The decrease in our R&D costs for the twelve months ended December 31, 2016, as compared to the same period in 2015, is attributable to lower employee
compensation and benefits costs, lower facilities rent and maintenance costs as well as lower other costs. A substantial portion of this decrease is due to the
realization of cost savings in connection with the Resource Optimization Program.

In addition, during 2015, we initiated the new confirmatory Phase 3 clinical trial of Macrilen™ (macimorelin), which explains the increase in costs for this
product candidate. The first patient was enrolled in the fourth quarter of 2015, we announced completion of patient recruitment in the fourth quarter of 2016
and  we  announced  top-line  results  of  the  trial  on  January  4,  2017.  Finally,  in  2015,  we  also  decided  to  suspend  our  efforts  on  internally  developing  Erk
inhibitor, a molecule for potential cancer therapies, to conserve our resources for other projects.

G&A expenses were $7.1 million for the year ended December 31, 2016, as compared to $11.3 million for the same period in 2015. The decrease in our
G&A costs for 2016, as compared to the same periods in 2015, is due to the recording of a provision, in the fourth quarter of 2015, related to a corporate
restructuring that we announced on October 12, 2015 (the "2015 Corporate Restructuring"). The 2015 Corporate Restructuring included the restructuring of
our finance and accounting staff and the closure of our office in Quebec City. As a result of the 2015 Corporate Restructuring, recurring G&A expenses also
decreased in 2016, as compared to 2015. Finally, the comparative decrease is also explained by certain transaction costs allocated to warrants in connection
with the completion of share issuances in March and December 2015.

Selling expenses were $6.7 million for the year ended December 31, 2016, as compared to $6.9 million for the same period in 2015. The selling expenses are
slightly below what we anticipated because we postponed some expenses related to the potential

commercial launch of Zoptrex™ and Macrilen™ (macimorelin) mainly because the related clinical trials took more time than expected.

Net finance income (costs) were $4.5 million for the year ended December 31, 2016, as compared to $(15.3) million for the same period in 2015 and are
comprised predominantly of the change in fair value of warrant liability and of gains and losses recorded due to changes in foreign currency exchange rates.

The change in fair value of our warrant liability results from the periodic "mark-to-market" revaluation, via the application of the pricing models, of share
purchase warrants that were outstanding during the relevant period. The "mark-to-market" warrant valuation was most notably impacted by the issuance of
3.1 million additional share purchase warrants in 2015 and by the closing price of our common shares, which, on the NASDAQ, fluctuated from $2.67 to
$4.94 during the year ended December 31, 2016 and from $4.00 to $84.20 during the year ended December 31, 2015.

In addition, with specific reference to 2015, finance costs were also impacted by the warrant exercise inducement fee paid to certain holders of the Series B
Warrants.

Net loss for the year ended December 31, 2016 was $(25.0) million, or $(2.41) per basic and diluted share compared to $(50.1) million, or $(18.14) per basic
and diluted share for the same period in 2015. The decrease in our net loss for the year ended December 31, 2016, as compared to the same period in 2015, is
due to the lower comparative R&D costs and G&A expenses and the change in fair value of warrant liability as presented above.

*    Net loss per share is based on the weighted average number of shares outstanding during each reporting period, which may differ on a quarter-to-quarter basis. As such, the sum of the quarterly
net loss per share amounts may not equal full-year net loss per share.

Historical  quarterly  results  of  operations  and  net  loss  cannot  be  taken  as  reflective  of  recurring  revenue  or  expenditure  patterns  or  of  predictable  trends,
largely given the non-recurring nature of certain components of our historical revenues, due most notably to unpredictable quarterly variations attributable to
our net finance income, which in turn are comprised mainly of the impact of the periodic "mark-to-market" revaluation of our warrant liability and of foreign
exchange gains and losses. Additionally, our net R&D costs have historically varied on a quarter-over-quarter basis due to the ramping up or winding down of
potential  product  candidate  activities,  which  in  turn  are  dependent  upon  many  factors  that  often  do  not  occur  on  a  linear  or  predictable  basis. Our  selling
expenses have been consistent but can also vary on a quarter-over-quarter basis due to the ramping up of pre-commercialization activities associated with
Macrilen™ (macimorelin).

1. Approximately $0.6 million and $1.5 million were denominated in EUR as at December 31, 2017 and December 31, 2016, respectively, and approximately $1.0 million and $3.7 million were

denominated in Canadian dollars as at December 31, 2017 and December 31, 2016, respectively.

2. Comprised mainly of employee future benefits, provisions for onerous contracts and non-current portion of deferred revenues.

The decrease in cash and cash equivalents as at December 31, 2017, as compared to December 31, 2016, is due to the net cash used in operating activities
including variations in components of our working capital. The decrease was partially offset by the net proceeds generated by various issuances of common
shares under our April 2016, March 2017 and April 2017 "At-the-Market" ("ATM") Programs.

The increase in inventory is the result of capitalizing direct manufacturing costs incurred from Macrilen™ (macimorelin) following its FDA approval.

The decrease in payables and other current liabilities is mainly attributable to the reduction in R&D costs and selling expenses, partially offset by an increase
in G&A expenses, in the fourth quarter of 2017 as compared to the fourth quarter of 2016 which is explained by the completion of our Phase 3 clinical trials.

The decrease in our warrant liability from December 31, 2016 to December 31, 2017 is mainly due to a net fair value revaluation gain of $2.2 million, which
was recorded pursuant to our periodic "mark-to-market" revaluation of the underlying outstanding share purchase warrants. The revaluation gain is mainly
explained  by  the  decrease  of  the  price  of  our  common  shares  during  the  period.  The  remaining  variance  is  explained  by  the  exercise  of  some  Series  A
Warrants in July 2017.

The increase in non-financial non-current liabilities from December 31, 2016 to December 31, 2017 is mainly due to the increase in the EUR/USD foreign
exchange rate offset by a slight increase in the discount rate used to estimate our employee future benefits obligation.

The decrease in shareholders' (deficiency) equity as at December 31, 2017, as compared to December 31, 2016, is attributable primarily to the recording of a
net loss for the twelve-month period, partially offset by the net proceeds generated by various issuances of common shares under our April 2016, March 2017
and April 2017 ATM Programs.

Recent Accounting Pronouncements

The IASB continues to issue new and revised IFRS. A listing of the recent accounting pronouncements promulgated by the IASB and not yet adopted by the
Company is included in note 4 to the Company's December 31, 2017 consolidated financial statements which are included in Item 18 of this Annual Report
on Form 20-F.

B.

Liquidity, Cash Flows and Capital Resources

Our  operations  and  capital  expenditures  have  been  financed  through  certain  transactions  impacting  our  cash  flows  from  operating  activities,  public  equity
offerings and issuances under various ATM programs.

At December 31, 2017, we had $7.8 million of cash and cash equivalents. We expect existing cash balances and operating cash flows (including the upfront
cash payment of $24 million from Strongbridge discussed below) will provide us with adequate funds to support our current operating plan for at least twelve
months after the date of the issuance of this Annual Report Form 20-F and for the foreseeable future.

Strongbridge License Agreement

On January 17, 2018, the Company received an upfront cash payment of $24,000,000 from Strongbridge, and, for as long as Macrilen™ (macimorelin) is
patent-protected,  the  Company  will  be  entitled  to  a  15%  royalty  on  net  sales  up  to  $75,000,000  and  an  18%  royalty  on  net  sales  above  $75,000,000.
Following the end of patent protection in United States or Canada for Macrilen™ (macimorelin), the Company will be entitled to a 5% royalty on net sales in
that country. In addition, the Company will also receive one-time payments from Strongbridge following the first achievement of the following commercial
milestone events:

•

•

•

•

•

$4,000,000 on achieving $25,000,000 annual net sales,

$10,000,000 on achieving $50,000,000 annual net sales,

$20,000,000 on achieving $100,000,000 annual net sales,

$40,000,000 on achieving $200,000,000 annual net sales, and

$100,000,000 on achieving $500,000,000 annual net sales.

Upon approval by the FDA of a pediatric indication for Macrilen™ (macimorelin), the Company will receive a one-time milestone payment of $5,000,000
from Strongbridge.

Strongbridge will fund 70% of the costs of a worldwide pediatric development program to be run by the Company with customary oversight from a joint
steering  committee.  The  joint  steering  committee  will  be  comprised  of  four  persons,  two  of  whom  will  be  appointed  by  each  of  Strongbridge  and  the
Company.

The Strongbridge License Agreement will expire at the end of a defined royalty period in each of the United States and Canada (the "Territory"), at which
time the license that the Company granted to Strongbridge will become irrevocable, fully paid-up, perpetual and royalty-free in such country. Strongbridge
has  the  right  to  terminate  the  Strongbridge  License  Agreement  if  there  is  a  safety  concern  related  to  Macrilen™  (macimorelin),  withdrawal  of  regulatory
approval for Macrilen™ (macimorelin) in the U.S. believed to be permanent, two hundred and seventy (270) days' prior written notice, or if the Company
commits a material breach of any term of the Strongbridge License Agreement that it fails to cure within 90 days after receiving written notice of the breach.
The  Company  has  the  right  to  terminate  the  Strongbridge  License  Agreement  if  Strongbridge  commits  a  material  breach  of  any  term  of  the  Strongbridge
License Agreement that it fails to cure within 90 days after receiving written notice of the breach. If the breach relates to Canada then the Company shall only
have the right to terminate the Strongbridge License Agreement in relation to Canada. If the breach relates to the United States, then the Company shall have
the right to terminate the Strongbridge License Agreement in its entirety.

46

The Strongbridge License Agreement contains customary provisions related to, among other things, confidentiality and non-disclosure, representations and
warranties, indemnity and dispute resolution. The Strongbridge License Agreement is governed by the laws of the State of New York, United States.

Public Offerings

On April 1, 2016, we entered into an ATM sales agreement under which we are able, at our discretion and from time to time, to sell up to 3 million of our
common shares through ATM issuances on the NASDAQ for aggregate gross proceeds of up to approximately $10 million (the "April 2016 ATM Program").
The ATM program provides that common shares are to be sold at market prices prevailing at the time of sale and, as a result, prices may vary. During the year
ended  December  31,  2016,  the  Company  issued  an  additional  555,068  common  shares  under  the  April  2016  ATM  Program  at  an  average  price  of
approximately $3.20 per share for gross proceeds of $1.8 million. The shelf registration statement pursuant to which this program was established expired on
March 28, 2017.

On March 28, 2017, we commenced a new ATM offering pursuant to its existing ATM Sales Agreement, dated April 1, 2016, under which we were able, at
our discretion, from time to time, to sell up to a maximum of 3 million common shares through ATM issuances on the NASDAQ, up to an aggregate amount
of $9.0 million (the "March 2017 ATM Program"). The common shares were to be sold at market prices prevailing at the time of the sale of the common
shares and, as a result, sale prices varied.

Between March 28, 2017 and April 18, 2017, we issued a total of 597,994 common shares under the March 2017 ATM Program at an average issuance price
of $2.97 per share for aggregate gross proceeds of $1.8 million less cash transaction costs of $55,000 and previously deferred financing costs of $65,000.

On April 27, 2017, we entered into a new ATM Sales Agreement (the "New ATM Sales Agreement"), and filed with the SEC a prospectus supplement (the
"Prospectus Supplement") related to sales and distributions of up to a maximum of 2,240,000 common shares through ATM issuances on the NASDAQ, up to
an aggregate amount of $6.9 million under the New ATM Sales Agreement. The common shares will be sold at market prices prevailing at the time of the sale
of the common shares and, as a result, prices may vary. The New ATM Sales Agreement and the Prospectus Supplement superseded and replaced the March
2017 ATM Program, which itself had superseded and replaced the April 2016 ATM Program. The Prospectus Supplement supplements the base prospectus
included in our Shelf Registration Statement on Form F-3, as amended (the "2017 Shelf Registration Statement"), which was declared effective by the SEC
on April 27, 2017. The 2017 Shelf Registration Statement allows us to offer up to $50 million of common shares and is effective for a three-year period.
Between May 30, 2017 and December 31, 2017, we issued 1.8 million common shares at an average issuance price of $1.71 per share under the New ATM
Sales Agreement.

On November 1, 2016, we completed a registered direct offering of 2,100,000 units (the "Units"), with each Unit consisting of one common share or one pre-
funded  warrant  to  purchase  one  common  share  and  0.45  of  a  warrant  to  purchase  one  common  share  (the  "November  2016  Offering").  Total  gross  cash
proceeds raised through the November 2016 Offering amounted to $7.6 million, less cash transaction costs of $1.0 million, including the placement agent's
fee and expenses. The warrants are exercisable six months after their date of issuance and for a period of three years thereafter at an exercise price of $4.70
per share. The warrants contain a call provision which provides that, in the event our common shares trade at or above $10.00 on the principal trading market
of our common shares during a specified measurement period and subject to a minimum volume of trading during such measurement period, then, subject to
certain  conditions,  we  have  the  right  to  call  for  cancellation  all  or  any  portion  of  the  warrants  which  are  not  exercised  by  holders  within  10  trading  days
following receipt of a call notice from us. Upon complete exercise for cash, these warrants would result in the issuance of an aggregate of 945,000 common
shares that would generate additional proceeds of approximately $4.4 million, although these warrants may be exercised on a "net" or "cashless" basis.

Operating Activities

2017 compared to 2016

Cash used in operating activities totaled $4.5 million and $22.9 million for the three and twelve months ended December 31, 2017, as compared to $8.1
million and $29.0 million for the same periods in 2016. The decrease in cash used in operating activities for the twelve months ended December 31, 2017, as
compared to the same periods in 2016, is mainly due to lower operating expenses.

We expect net cash used in operating activities to range from $11.0 million to $12.0 million for the year ending December 31, 2018. We expect most of the
expenses related to G&A to be for employee, insurance, rent, travel, and professional fees, such as legal, accounting and public company related expenses.
The timing of the termination notices, that will be given to employees as part of the 2017 German Restructuring, will have an impact on the net cash used in
operating  activities.  This  guidance  may  vary  significantly  in  future  periods  and  it  can  also  be  significantly  impacted  by  ongoing  business  development
initiatives.

2016 compared to 2015

Cash  used  in  operating  activities  totaled  $29.0  million  and  $33.8  million  for  the  twelve months  ended  December  31,  2016 and  2015,  respectively.  The
decrease in cash used in operating activities for the twelve months ended December 31, 2016, as compared to the same period in 2015, was mainly due to
lower operating expenses.

Financing Activities

2017 compared to 2016

Cash flows from financing activities totaled $0.0 million and $8.0 million for the three and twelve months ended December 31, 2017, as compared to $9.4
million and $9.9 million for the same periods in 2016. The decrease is mainly due to higher net proceeds received from the November 2016 Offering.

Cash flows from financing activities totaled $9.9 million for the twelve months ended December 31, 2016, as compared to $40.8 million for the same period
in 2015. The decrease is mainly due to lower net proceeds received from the issuance of common shares and warrants in 2016 as compared to 2015.

Investing Activities

2017 compared to 2016

Cash  (used  in)  provided  by  investing  activities  totaled  $0.1  million  and  $0.3  million  for  the  three  and  twelve  months  ended  December  31,  2017,  as
compared to $0.0 million and $(0.3) million for the same periods in 2016.

2016 compared to 2015

Cash  (used  in)  provided  by  investing  activities  totaled  $(0.3)  million  and  $0.9  million  for  the  twelve  months  ended  December  31,  2016  and  2015,
respectively. The decrease for the twelve-month period ended December 31, 2016, as compared to the same period in 2015, is due to proceeds received in
connection with the disposal of equipment in connection with our Resource Optimization Program during the first quarter of 2015.

Critical Accounting Policies, Estimates and Judgments

Our consolidated financial statements as at December 31, 2017 and December 31, 2016 and for the years ended December 31, 2017, 2016  and  2015  have
been prepared in accordance with IFRS as issued by the IASB.

The preparation of consolidated financial statements in accordance with IFRS requires management to make judgments, estimates and assumptions that affect
the  reported  amounts  of  our  assets,  liabilities,  revenues,  expenses  and  related  disclosures.  Judgments,  estimates  and  assumptions  are  based  on  historical
experience, expectations, current trends and other factors that management believes to be relevant when our consolidated financial statements are prepared.

Management reviews, on a regular basis, the Company's accounting policies, assumptions, estimates and judgments in order to ensure that the consolidated
financial statements are presented fairly and in accordance with IFRS. Revisions to accounting estimates are recognized in the period in which the estimates
are revised and in any future periods affected.

Critical accounting estimates and assumptions, as well as critical judgments used in applying accounting policies in the preparation of our interim condensed
consolidated financial statements were the same as those that applied to our annual consolidated financial statements as of December 31, 2017 and December
31, 2016 and for the years ended December 31, 2017, 2016 and 2015.

Capital Disclosures

Our  objective  in  managing  capital,  consisting  of  shareholders'  equity,  with  cash  and  cash  equivalents  and  restricted  cash  equivalents  being  its  primary
components, is to ensure sufficient liquidity to fund R&D costs, selling expenses, G&A expenses, working capital and capital expenditures.

Over the past several years, we have increasingly raised capital via public equity offerings and drawdowns and issuances under various ATM sales programs
as our primary source of liquidity.

Our capital management objective remains the same as that in previous periods. The policy on dividends is to retain cash to keep funds available to finance
the activities required to advance our product development portfolio and to pursue appropriate commercial opportunities as they may arise. We are not subject
to any capital requirements imposed by any regulators or by any other external source.

Outlook for 2018

Product Development

Macrilen™ (macimorelin)

Macrilen™ (macimorelin), a ghrelin receptor agonist, is a novel orally-active small molecule that stimulates the secretion of growth hormone. Macrilen™
(macimorelin) has been granted orphan drug designation by the FDA for the evaluation of growth hormone deficiency. We own the worldwide rights to this
novel patented compound. Macrilen™ (macimorelin) is our proposed trade name for macimorelin. The proposed trade name is subject to approval by the
FDA.  On  September  25,  2017,  the  FDA  rejected  the  Company's  proposed  trade  name  Macrilen™  (macimorelin)  due  to  orthographic  similarities  and
overlapping  product  characteristics.  Subsequently,  on  October  11,  2017  the  Company  appealed  the  FDA's  decision  rejecting  the  proposed  trade  name
Macrilen™ (macimorelin). On October 26, 2017, the FDA granted a user fee goal date of January 9, 2018 for the use of the proposed trade name, Macrilen™
(macimorelin).  On  November  15,  2017,  the  FDA  concluded  that  the  use  of  the  proposed  proprietary  name,  Macrilen™  (macimorelin),  is  conditionally
acceptable.  On  December  16,  2016,  we  were  advised  by  the  EMA  that  Macrilen™  (macimorelin)  was  rejected  as  the  proposed  invented  name  for
macimorelin because of its similarity to the names of other medicines. On March 8, 2018, we applied for two invented names for macimorelin: Macrilen ST
and Macrilen GHST.

On January 16, 2018, through AEZS Germany, we entered into the Strongbridge License Agreement. We received an upfront cash payment of $24,000,000
from  Strongbridge,  and,  for  as  long  as  Macrilen™  (macimorelin)  is  patent-protected,  the  Company  will  be  entitled  to  a  15%  royalty  on  net  sales  up  to
$75,000,000  and  an  18%  royalty  on  net  sales  above  $75,000,000.  Following  the  end  of  patent  protection  in  United  States  or  Canada  for  Macrilen™
(macimorelin), the Company will be entitled to a 5% royalty on net sales in that country. In addition, the Company will also receive one-time payments from
Strongbridge following the first achievement of the following commercial milestone events:

•

•

•

•

•

$4,000,000 on achieving $25,000,000 annual net sales,

$10,000,000 on achieving $50,000,000 annual net sales,

$20,000,000 on achieving $100,000,000 annual net sales,

$40,000,000 on achieving $200,000,000 annual net sales, and

$100,000,000 on achieving $500,000,000 annual net sales.

Upon approval by the FDA of a pediatric indication for Macrilen™ (macimorelin), the Company will receive a one-time milestone payment of $5,000,000
from Strongbridge.

Strongbridge will fund 70% of the costs of a worldwide pediatric development program to be run by the Company with customary oversight from a joint
steering  committee.  The  joint  steering  committee  will  be  comprised  of  four  persons,  two  of  whom  will  be  appointed  by  each  of  Strongbridge  and  the
Company.

The commercial success of Macrilen™ (macimorelin) will depend on several factors, including, but not limited to, the receipt of approvals from the EMA and
similar  foreign  regulatory  authorities;  developing  appropriate  distribution  and  marketing  infrastructure  and  arrangements  for  our  product;  launching  and
growing commercial sales of the product; and acceptance of the product in the medical community, among patients and with third party payers. We are not
currently conducting any clinical studies.

We continue to explore various alternatives to monetize our rights to macimorelin in other countries around the globe.

We also continue to seek opportunities to in-license and acquire products. Our goal is to become a growth-oriented specialty biopharmaceutical company by
pursuing  successful  development,  commercialization  and  licensing  of  a  product  portfolio  achieving  successful  commercial  presence  and  growth,  while
consistently delivering value to our shareholders, employees and the medical providers and patients who will benefit from our products.

Commercial Operations

Our commercial operations were significantly reduced in the fourth quarter of 2017. We eliminated our contract sales team in its entirety, as well as remaining
sales  management  in  November  2017,  in  accordance  with  the  terms  of  our  agreement  with  inVentiv  Commercial  Services,  LLC,  an  affiliate  of  inVentiv
Health, Inc. ("inVentiv"), a contract-sales organization. Our agreement with inVentiv commenced in November 2014.

Pursuant to termination of the inVentiv agreement, we ended our co-promotion with EMD Serono and Armune.

Summary of key expectations for revenues, operating expenditures and cash flows

The following represents forward-looking information and users are cautioned that actual results may vary.

Excluding the impact of future foreign exchange rate fluctuations, we expect that we will incur R&D costs of between $1.0 million and $2.0 million for the
year ending December 31, 2018. We expect most of the expenses related to R&D to be for employee, commercial service, patent and consultant costs related
to the Macrilen™ (macimorelin) PIP study (which Strongbridge will fund 70%).

Based on currently available information, we expect selling expenses to range between $0.2 million and $0.5 million during the year ending December 31,
2018. We expect most of the expenses related to selling to be for website, branding and marketing.

Excluding the impact of foreign exchange rate fluctuations, we expect G&A expenses to range between $10.0 million and $11.0 million for the year ending
December  31,  2018.  We  expect  most  of  the  expenses  related  to  G&A  to  be  for  employee,  insurance,  rent,  travel,  and  professional  fees,  such  as  legal,
accounting and public company related expenses.

Excluding any foreign exchange impacts, as well as income from new business development initiatives, we expect that our overall use of cash for operations
in December 31, 2018 will range from $11.0 million to $12.0 million, as we continue to fund ongoing operating activities and working capital requirements
and as outlined in the above paragraphs.

Compensation Discussion & Analysis

Compensation Philosophy and Objectives

Our Board, through the NGCC, establishes our executive compensation program that is market-based and at a competitive percentile grouping for both total
cash and total direct compensation. The NGCC has established a compensation program that is designed

to attract, motivate and retain high-performing senior executives, encourage and reward superior performance and align the executives' interests with those of
our shareholders by:

•

•

•

•

providing the opportunity for an executive to earn compensation that is competitive with the compensation received by executives serving in the same or
measurably similar positions within comparable companies;

providing the opportunity for executives to participate in equity-based incentive compensation plans;

aligning executive compensation with our corporate objectives; and

attracting and retaining highly qualified individuals in key positions.

Compensation Elements

Our executive compensation is targeted at the 50th percentile for small cap biopharmaceutical companies within both the local and national markets and is
comprised of both fixed and variable components. The variable components include equity and non-equity incentive plans. Each compensation component is
intended to serve a different function, but all elements are intended to work in concert to maximize both corporate and individual performance by establishing
specific, competitive operational and corporate goals and by providing financial incentives to employees based on their level of attainment of these goals.

Our  current  executive  compensation  program  is  comprised  of  the  following  four  basic  components:  (i)  base  salary;  (ii)  an  annual  bonus  linked  to  both
individual and corporate performance; (iii) equity incentives, consisting solely of stock options granted under our second amended and restated stock option
plan adopted by the Board on March 29, 2016 and ratified by the shareholders of Aeterna on May 10, 2016 (the "Stock Option Plan") established for the
benefit of our directors, certain executive officers and other participants as may be designated from time to time by either the Board or the NGCC; and (iv)
other elements of compensation, consisting of benefits, perquisites and retirement benefits.

Base Salary. Base salaries are intended to provide a steady income to our executive officers regardless of share price. In determining individual base salaries,
the NGCC takes into consideration individual circumstances that may include the scope of an executive's position, the executive's relevant competencies or
experience and retention risk. The NGCC also takes into consideration the fulfillment of our corporate objectives, as well as the individual performance of the
executive.

Short-Term, Non-Equity Incentive Compensation. Our short-term, non-equity incentive compensation plan sets a target cash bonus for each executive officer,
expressed as a percentage of the executive officer's base salary. The amount of cash bonus paid to an executive officer depends on the extent to which he or
she contributed to the achievement of the annual performance objectives established by the Board for the year. The annual performance objectives are specific
operational, clinical, regulatory, financial, commercial and corporate goals that are intended to advance our product pipeline, to promote the success of our
commercial efforts and to enhance our financial position. The annual performance objectives are set at the end of each financial year as part of the annual
review  of  corporate  strategies.  The  performance  objectives  are  not  established  for  individual  executive  officers  but  rather  by  functional  area(s),  many  of
which are carried out by or fall within the responsibility of our President and Chief Executive Officer, Chief Financial Officer (or principal financial officer)
and our other executive officers, including our Named Executive Officers. The award of a cash bonus requires the approval of both the NGCC and the Board
and is based upon an assessment of each individual's performance, as well as our overall performance at a corporate level. The determination of individual
performance does not involve quantitative measures using a mathematical calculation in which each individual performance objective is given a numerical
weight. Instead, the NGCC's determination of individual performance is a subjective determination as to whether a particular executive officer substantially
achieved the stated objectives or over-performed or under-performed with respect to corporate objectives that were deemed to be important to our success.

Long-Term Equity Compensation Plan of Executive Officers. The long-term component of the compensation of our executive officers is based exclusively on
the Stock Option Plan, which permits the award of a number of options based on the contribution of the officers and their responsibilities. The Board adopted
a policy regarding stock option grants in December 2014 (the "2014 Stock Option Policy"), which provides that each Named Executive Officer is eligible to
receive options to acquire our Common Shares having a value, based on the Black-Scholes option pricing model, equal to a specified multiple of his or her
salary. The specified multiple for the President and Chief Executive Officer is 1.5. The specified multiple for each other Named Executive Officer is 0.75. To
encourage retention and focus management on developing and successfully implementing our continuing growth strategy, stock options vest over a period of
three years, with the first third vesting on the first anniversary of the date of grant. Stock options are usually granted to executive officers in December of each
year.

Other Forms of Compensation. Our executive employee benefits program also includes life, medical, dental and disability insurance to the same extent and in
the same manner as all other employees. Several  of  our  executive  officers  also  receive  a  car  allowance  as  a  perquisite.  These benefits and perquisites are
designed to be competitive overall with equivalent positions in comparable

58

North American organizations in the life sciences industry. We also contribute to our North American employees' retirement plans to the extent of 50% of the
employee's contribution up to an annual maximum amount of $9,000 for employees in the United States, and up to a maximum of $12,000 for employees and
executive officers over 50 years old in the United States. The contribution amounts for our United States employees are subject to limitations imposed by the
United States Internal Revenue Service on contributions to our most highly compensated employees. Employees based in Frankfurt, Germany also benefit
from  certain  employer  contributions  into  the  employees'  pension  funds.  Our  executive  officers,  including  the  Named  Executive  Officers,  are  eligible  to
participate in such employer-contribution plans to the same extent and in the same manner as all other employees.

Positioning

The NGCC is authorized to engage its own independent consultant to advise it with respect to executive compensation matters. While the NGCC may rely on
external information and advice, all of the decisions with respect to executive compensation are made by the Board upon the recommendation of the NGCC
and may reflect factors and considerations other than, or that may differ from, the information and recommendations provided by any external compensation
consultants that may be retained from time to time.

In 2013, the NGCC retained a compensation consultant to benchmark our executive compensation plan in an effort to determine whether we were achieving
our objective of providing market competitive compensation opportunities. The compensation consultant gathered compensation data from companies that it
concluded were of comparable size and/or stage of development as us and from other companies with which we compete for executive talent and advised the
NGCC that our executive compensation should be generally aligned with the 50th percentile, or the mid-point, of the companies surveyed by the consultant.
Furthermore, the consultant advised the NGCC that the total cash target payment (base salary and, if applicable or awarded in cash, annual bonus) for our
executive officers in 2013 generally fell around the 50th percentile of the companies surveyed. The NGCC did not repeat or update the benchmarking process
in  2014,  2015,  2016  or  2017  because  it  concluded  that  doing  so  would  not  provide  additional  meaningful  data,  considering  the  expense  of  the  process.
However, the NGCC, as a matter of good governance, will review and assess the current compensation program and make appropriate adjustments, if any,
during 2018.

Risk Assessment of Executive Compensation Program

The Board, through the NGCC, oversees the implementation of compensation methods that tie a portion of executive compensation to our short-term and
longer-term performance and that of each executive officer and that take into account the advantages and risks associated with such compensation methods. In
addition, the Board oversees the creation of compensation policies that are intended to reward the creation of shareholder value while reflecting a balance
between our short-term and longer-term performance and that of each executive officer. The NGCC has considered in general terms the concept of risk as it
relates to our executive compensation program.

Base salaries are fixed in amount to provide a steady income to the executive officers regardless of share price and thus do not encourage or reward risk-
taking to the detriment of other important business, operational, commercial or clinical metrics or milestones. The variable compensation elements (annual
bonuses  and  stock  options)  are  designed  to  reward  each  of  short-term,  mid-term  and  long-term  performance.  For  short-term  performance,  a  discretionary
annual  bonus  may  be  awarded  based  on  the  timing  and  level  of  attainment  of  specific  operational  and  corporate  goals  that  the  NGCC  believes  to  be
challenging, yet does not encourage unnecessary or excessive risk-taking. While our bonus payments are generally based on annual performance, a maximum
bonus payment is pre-fixed for each senior executive officer and represents only a portion of each individual's overall total compensation opportunities. In
exceptional circumstances, a particular executive officer may be awarded a bonus that exceeds his or her maximum pre-fixed or target bonus amount. Finally,
a significant portion of executive compensation is provided in the form of stock options, which is intended to further align the interests of executives with
those of shareholders. The NGCC believes that these awards do not encourage unnecessary or excessive risk-taking since the ultimate value of the awards is
tied to our share price, and in the case of grants under the long-term incentive compensation plan, are generally subject to mid-term and long-term vesting
schedules to help ensure that executives generally have significant value tied to long-term share price performance.

The  NGCC  believes  that  the  variable  compensation  elements  (annual  bonuses  and  stock  options)  represent  a  percentage  of  overall  compensation  that  is
sufficient to motivate our executive officers to produce superior short-term, mid-term and long-term corporate results, while the fixed compensation element
(base salary) is also sufficient to discourage executive officers from taking unnecessary or excessive risks. The NGCC and the Board also generally have the
discretion to adjust annual bonuses and stock option grants based on individual performance and any other factors they may determine to be appropriate in the
circumstances. Such factors may include, where necessary or appropriate, the level of risk-taking a particular executive officer may have engaged in during
the preceding year.

Based on the foregoing, the NGCC has not identified any specific risks associated with our executive compensation program that are reasonably likely to
have  a  material  adverse  effect  on  us.  The  NGCC  believes  that  our  executive  compensation  program  does  not  encourage  or  reward  any  unnecessary  or
excessive risk-taking behavior.

59

Our directors, executive officers and employees are prohibited from purchasing, selling or otherwise trading in derivative securities relating to our Common
Shares. Derivative securities are securities whose value varies in relation to the price of our securities. Examples of derivative securities include warrants to
purchase  our  Common  Shares,  and  put  or  call  options  written  on  our  Common  Shares,  as  well  as  individually  arranged  derivative  transactions,  such  as
financial  instruments,  including,  for  greater  certainty,  pre-paid  variable  forward  contracts,  equity  swaps,  collars,  or  units  of  exchange  funds,  which  are
designed  to  hedge  or  offset  a  decrease  in  market  value  of  our  equity  securities  granted  as  executive  compensation  or  directors'  remuneration.  Options  to
acquire Common Shares issued pursuant to our Stock Option Plan are not derivative securities for this purpose.

60

2017 Compensation

Base Salary. The primary element of our compensation program is base salary. Our view is that a competitive base salary is a necessary element for retaining
qualified executive officers. In determining individual base salaries, the NGCC takes into consideration individual circumstances that may include the scope
of an executive's position, the executive's relevant competencies or experience and retention risk. The NGCC also takes into consideration the fulfillment of
our corporate objectives, as well as the individual performance of the executive.

Short-Term, Non-Equity Incentive Compensation. The Board, based on the NGCC's recommendation, adopted the following performance objectives for 2017:

The Board approved option awards to Mr. Ward on August 15, 2017 in accordance with the Stock Option Plan. Mr. Ward was awarded 150,000 stock options.
The stock options have an exercise price of $2.05 and vest in three annual installments commencing on August 15, 2018.

Summary of the Stock Option Plan

We established the Stock Option Plan in order to attract and retain directors, officers, employees and suppliers of ongoing services, who will be motivated to
work towards ensuring our success. The Board has full and complete authority to interpret the Stock Option Plan, to establish applicable rules and regulations
and to make all other determinations it deems necessary or useful for the administration of the Stock Option Plan, provided that such interpretations, rules,
regulations and determinations are consistent with the rules of all stock exchanges and quotation systems on which our securities are then traded and with all
relevant securities legislation.

The Stock Option Plan provides that the sole persons eligible to receive grants under the Stock Option Plan (each, a "Participant") shall be: (i) our most senior
executive  officers,  including  the  persons  occupying  the  positions  of  Chief  Executive  Officer,  Chief  Financial  Officer,  Chief  Scientific  Officer,  Chief
Commercial  Officer,  Chief  Administrative  Officer  and  Chief  Compliance  Officer;  (ii)  such  other  of  our  executive  officers  or  executive  officers  of  our
subsidiaries that may, from time to time, report directly to the Chief Executive Officer; (iii) the non-employee, independent members of the Board; and (iv)
such other of our officers or employees or the officers or employees of any of our subsidiaries, as the case may be, or suppliers of ongoing services, as may be
expressly designated by resolution of the Board or the NGCC.

The maximum number of Common Shares issuable under the Stock Option Plan is fixed at 11.4% of the issued and outstanding Common Shares at any given
time, which, as of March 27, 2018, represented approximately 1.9 million Common Shares. There were 711,252 options outstanding under the Stock Option
Plan representing approximately 4.3% of all issued and outstanding Common Shares on March 27, 2018.

Under the Stock Option Plan, (i) the number of securities issuable to insiders, at any time, or issued within any one-year period, under all of our security-
based compensation arrangements, cannot exceed 10% of our issued and outstanding securities and (ii) no single Participant may hold options to purchase,
from time to time, more than 5% of our issued and outstanding Common Shares. In addition: (i) the aggregate fair value of options granted under all of our
security-based compensation arrangements to any one of our Outside Directors entitled to receive a benefit under the Stock Option Plan, within any one-year
period, cannot exceed $100,000 valued on a Black-Scholes basis and as determined by the NGCC; and (ii) the aggregate number of securities issuable to all
of our Outside Directors entitled to receive a benefit under the Stock Option Plan, within any one-year period, under all of our security-based compensation
arrangements, cannot exceed 1% of its issued and outstanding securities.

Options granted under the Stock Option Plan may be exercised at any time within a maximum period of seven or ten years following the date of their grant
(the  "Outside  Expiry  Date"),  depending  on  the  date  of  grant.  The  Board  or  the  NGCC,  as  the  case  may  be,  designates,  at  its  discretion,  the  specific
Participants to whom stock options are granted under the Stock Option Plan and determines the number of Common Shares covered by each of such option
grants, the grant date, the exercise price of each option, the Outside Expiry Date and any other matter relating thereto, in each case in accordance with the
applicable rules and regulations of the regulatory authorities. The price at which the Common Shares may be purchased may not be lower than the greater of
the closing prices of the Common Shares on the NASDAQ on the last trading day preceding the date of grant of the option. Options granted under the Stock
Option  Plan  shall  vest  in  equal  tranches  over  a  three-year  period  (one-third  each  year,  starting  on  the  first  anniversary  of  the  grant  date)  or  as  otherwise
determined  by  the  Board  or  the  NGCC,  as  the  case  may  be.  Participants  may  not  assign  their  options  (nor  any  interest  therein)  other  than  by  will  or  in
accordance with the applicable laws of estates and succession.

Unless the Board or the NGCC decides otherwise, Participants cease to be entitled to exercise their options under the Stock Option Plan: (i) immediately, in
the event a Participant who is an officer or employee resigns or voluntarily leaves his or her employment or his or her employment is terminated with cause
and, in the case of a Participant who is a non-employee director of us or one of our subsidiaries, the date on which such Participant ceases to be a member of
the  relevant  Board  of  Directors;  (ii)  six  months  following  the  date  on  which  employment  is  terminated  as  a  result  of  the  death  of  a  Participant  who  is  an
officer  or  employee  and,  in  the  case  of  a  Participant  who  is  an  Outside  Director,  six  months  following  the  date  on  which  such  Participant  ceases  to  be  a
member of the Board of Directors by reason of death; (iii) 90 days following the date on which a Participant's employment is terminated for a reason other
than those mentioned in (i) or (ii) above including, without limitation, upon the disability, long-term illness, retirement or early retirement of the Participant;
and (iv) where the Participant is a service supplier, 30 days following the date on which such Participant ceases to act as such, for any cause or reason (each,
an "Early Expiry Date").

The Stock Option Plan also provides that, if the expiry date of one or more options (whether an Early Expiry Date or an Outside Expiry Date) occurs during a
"blackout period" or within the seven business days immediately after a blackout period imposed by

62

us, the expiry date will be automatically extended to the date that is seven business days after the last day of the blackout period. For the purposes of the
foregoing, "blackout period" means the period during which trading in our securities is restricted in accordance with our corporate policies.

If (i) we accept an offer to amalgamate, merge or consolidate with any other entity (other than one of our wholly-owned subsidiaries) or to sell or license all
or substantially all of our assets to any other entity (other than one of our wholly-owned subsidiaries); (ii) we sign a support agreement in customary form
pursuant to which the Board agrees to support a takeover bid and recommends that our shareholders tender their Common Shares to such takeover bid; or (iii)
holders of more than 50% of our then outstanding Common Shares tender all of their Common Shares to a takeover bid made to all of the holders of the
Common  Shares  to  purchase  all  of  the  then  issued  and  outstanding  Common  Shares,  then,  in  each  case,  all  of  the  outstanding  options  shall,  without  any
further action required to be taken by us, immediately vest. Each Participant shall thereafter be entitled to exercise all of such options at any time up to and
including, but not after the close of business on that date which is ten days following the Closing Date (as defined below). Upon the expiration of such ten-
day period, all rights of the Participant to such options or to the exercise of same (to the extent not already exercised) shall automatically terminate and have
no  further  force  or  effect  whatsoever.  "Closing  Date"  is  defined  to  mean  (x)  the  closing  date  of  the  amalgamation,  merger,  consolidation,  sale  or  license
transaction in the case of clause (i) above; (y) the first expiry date of the takeover bid on which each of the offeror's conditions are either satisfied or waived
in the case of clause (ii) above; or (z) the date on which it is publicly announced that holders of greater than 50% of our then outstanding Common Shares
have tendered their Common Shares to a takeover bid in the case of clause (iii) above.

The Stock Option Plan provides that the following amendments may be made to the plan only upon approval of each of the Board and our shareholders as
well as receipt of all required regulatory approvals:

•

•

•

•

•

•

•

•

•

•

the  addition  of  a  deferred  or  restricted  share  unit  component  or  any  other  provision  that  results  in  employees  receiving  securities  while  no  cash
consideration is received by us;

with respect to any Participant, whether or not such Participant is an "insider" and except in respect of certain permitted adjustments, such as in the case
of stock splits, consolidations or reclassifications:

any reduction in the exercise price of any option after the option has been granted, or

any cancellation of an option and the re-grant of that option under different terms, or

any extension to the term of an option beyond its Outside Expiry Date to a Participant who is an "insider" (except for extensions made in the context of a
"blackout period");

any amendment to the method of determining the exercise price of an option granted pursuant to the Stock Option Plan;

the addition of any form of financial assistance or any amendment to a financial assistance provision which is more favorable to employees; and

any amendment to the foregoing amending provisions requiring Board, shareholder and regulatory approvals.

The Stock Option Plan further provides that the following amendments may be made to the Stock Option Plan upon approval of the Board and upon receipt of
all required regulatory approvals, but without shareholder approval:

amendments regarding the extension of an option beyond an Early Expiry Date in respect of any Participant, or the extension of an option beyond the
Outside Expiry Date in respect of any Participant who is a "non-insider";

adjustments to the number of issuable Common Shares underlying, or the exercise price of, outstanding options resulting from a split or a consolidation
of the Common Shares, a reclassification, the payment of a stock dividend, the payment of a special cash or non-cash distribution to our shareholders on
a pro rata basis provided such distribution is approved by our shareholders in accordance with applicable law, a recapitalization, a reorganization or any
other event which necessitates an equitable adjustment to the outstanding options in proportion with corresponding adjustments made to all outstanding
Common Shares;

discontinuing or terminating the Stock Option Plan; and

any other amendment which does not require shareholder approval under the terms of the Stock Option Plan.

monthly limit. Dr. Sachse also contributes a percentage of his salary to the plan. We are liable to Dr. Sachse for the pension benefits that have been promised, if the private pension provider

C.

Board practices

Our  Articles  provide  that  our  Board  shall  be  composed  of  a  minimum  of  five  and  a  maximum  of  15  directors.  Directors  are  elected  annually  by  our
shareholders, but the directors may from time to time appoint one or more directors, provided that the total number of directors so appointed does not exceed
one-third of the number of directors elected at the last annual meeting of shareholders. Each elected director will remain in office until termination of the next
annual meeting of the shareholders or until his or her successor is duly elected or appointed, unless his or her post is vacated earlier. We do not have service
agreements with our independent directors.

See Item 6A. for information about the period of service of each of our directors and senior corporate officers.

Standing Committees of the Board of Directors    

67

Our Board has established an Audit Committee and a NGCC.

Audit Committee

The Audit Committee assists the Board in fulfilling its oversight responsibilities. The Audit Committee reviews the financial reporting process, the system of
internal control, the audit process, and our process for monitoring compliance with laws and regulations and with our Code of Ethical Conduct. In performing
its duties, the Audit Committee will maintain effective working relationships with the Board, management, and the external auditors. To effectively perform
his  or  her  role,  each  committee  member  will  obtain  an  understanding  of  the  detailed  responsibilities  of  committee  membership  as  well  as  our  business,
operations and risks.

The function of the Audit Committee is oversight and while it has the responsibilities and powers set forth in its charter (incorporated by reference to Exhibit
11.3 to this Annual Report on Form 20-F), it is neither the duty of the committee to plan or to conduct audits or to determine that our financial statements are
complete, accurate and in accordance with generally accepted accounting principles, nor to maintain internal controls and procedures.

The current members of the Audit Committee are Gérard Limoges (Chair), Michael Cardiff and Juergen Ernst.

NGCC

The NGCC is responsible for, among other matters, (i) assisting the Board in developing our approach to corporate governance issues, (ii) proposing new
Board nominees, (iii) overseeing the assessment of the effectiveness of the Board and its committees, their respective chairs and individual directors and (iv)
making recommendations to the Board with respect to board member nominees and directors' compensation, as well as serving in a leadership role for our
corporate governance practices. It is also responsible for taking all reasonable actions to ensure that appropriate human resources policies, procedures and
systems, e.g., recruitment and retention policies, competency and performance metrics and measurements, training and development programs, and market-
based, competitive compensation and benefits structures, are in place so that we can attract, motivate and retain the quality of personnel required to achieve
our business objectives. The NGCC also assists the Board in discharging its responsibilities relating to the recruitment, retention, development, assessment,
compensation and succession planning for our executive and senior management members.

Thus, the NGCC recommends the appointment of senior officers, including the terms and conditions of their appointment and termination, and reviews the
evaluation  of  the  performance  of  our  senior  officers,  including  recommending  their  compensation  and  overseeing  risk  identification  and  management  in
relation  to  executive  compensation  policies  and  practices.  The  Board,  which  includes  the  members  of  the  NGCC,  reviews  the  Chief  Executive  Officer's
corporate strategy, goals and performance objectives and evaluates and measures his or her performance and compensation against the achievement of such
goals and objectives.

The NGCC recognizes that the industry, regulatory and competitive environment in which we operate requires a balanced level of risk-taking to promote and
achieve the performance expectations of executives of a specialty biopharmaceutical company that is also seeking to acquire or in-license new commercial
products. The NGCC is of the view that our executive compensation program should not encourage senior executives to take inappropriate or unreasonable
risk.  In  this  regard,  the  NGCC  recommends  the  implementation  of  compensation  methods  that  appropriately  connect  a  portion  of  senior  executive
compensation with our short-term and longer-term performance, as well as that of each individual executive officer and that take into account the advantages
and risks associated with such compensation methods. The NGCC is also responsible for establishing compensation policies that are intended to reward the
creation of shareholder value while reflecting a balance between our short-term and longer-term performance and that of each executive officer.

The current members of the Compensation Committee are Carolyn Egbert (Chair), Juergen Ernst and Michael Cardiff.

D.

Employees

As at December 31, 2017, we had a total of 34 active employees, of which 30 are based in Frankfurt, Germany. The remaining four employees are based in
the  United  States.  Our  employees  are  engaged  in  the  following  activities:  (i)  22 are  engaged  in  research  and  development,  regulatory  affairs  and  quality
assurance; (ii) four are involved in commercial operations and business development; and (iii) 8 are involved in various administrative functions, including
finance and accounting. We do not employ any sales representatives. Under the 2017 German Restructuring, we terminated 22 employees of our German
subsidiary  as  of  December  31,  2017.  We  have  agreements  with  our  employees  covering  confidentiality,  loyalty,  non-competition  and  assignment  of  all
intellectual property rights developed during the employment period.

Item 7.

Major Shareholders and Related Party Transactions

A.

Major shareholders

We are not directly or indirectly owned or controlled by another corporation or by any foreign government. Based on filings with the SEC and the Canadian
securities regulatory authorities, as at March 27, 2018, no individual or entity beneficially owned, directly or indirectly, or exercised control or direction over
our Common Shares carrying more than 5% of the voting rights attached to all our Common Shares.

United States Shareholders

As at March 27, 2018, there were 39 holders of record of our Common Shares, of which six were registered with an address in the United States holding in
the  aggregate  approximately  99.8%  of  our  outstanding  Common  Shares.  We  believe  that  the  number  of  beneficial  owners  of  our  Common  Shares  is
substantially greater than the number of record holders, because the overwhelming majority of our Common Shares are held in broker "street names".

B.

Related party transactions

Other than employment agreements and indemnification agreements with our management, there are no related party transactions.

Memorandum and articles of association

We  are  governed  by  our  restated  articles  of  incorporation  (the  "Restated  Articles  of  Incorporation")  under  the  CBCA  and  by  articles  of  amendment  dated
October 2, 2012 and November 17, 2015 (together with the Restated Articles of Incorporation, the "Articles") and by our bylaws, as amended and restated on
March 21, 2013 (the "bylaws"). Our Articles are on file with Corporations Canada under Corporation Number 264271-9. The Articles do not include a stated
purpose and do not place any restrictions on the business that we may carry on.

Inspection Rights of Shareholders

Under  the  CBCA,  shareholders  are  entitled  to  be  provided  with  a  copy  of  the  list  of  our  registered  shareholders.  In  order  to  obtain  the  shareholder  list,  a
shareholder must provide to us an affidavit including, among other things, a statement that the list will only be used for the purposes permitted by the CBCA.
These permitted purposes include an effort to influence the voting of our shareholders, an offer to acquire our securities and any other matter relating to our
affairs. We are entitled to charge a reasonable fee for the provision of the shareholder list and must deliver that list no more than ten days after receipt of the
affidavit described above.

Under the CBCA, shareholders have the right to inspect certain corporate records, including our Articles and bylaws and minutes of meetings and resolutions
of the shareholders. Shareholders have no statutory right to inspect minutes of meetings and resolutions of our directors. Our shareholders have the right to
certain financial information respecting us. In addition to the annual and quarterly financial statements required to be filed under applicable securities laws,
we  are  required  by  the  CBCA  to  place  before  every  annual  meeting  of  shareholders  our  audited  comparative  annual  financial  statements.  In  addition,
shareholders have the right to examine the financial statements of each of our subsidiaries and any other corporate entity whose accounts are consolidated in
our financial statements.

Directors

The minimum number of directors we must have is five and the maximum number is 15. In accordance with the CBCA, at least 25% of our directors must be
residents of Canada. In order to serve as a director, a person must be a natural person at least 18 years of age, of sound mind, not bankrupt, and must not be
prohibited by any court from holding the office of director. None of the Articles, the bylaws and the CBCA imposes any mandatory retirement requirements
for directors.

The directors are elected by a majority of the votes cast at the annual meeting at which an election of directors is required, to hold office until the election of
their  successors,  except  in  the  case  of  resignations  or  if  their  offices  become  vacant  by  death  or  otherwise.  Subject  to  the  provisions  of  our  bylaws,  all
directors may, if still qualified to serve as directors, stand for re-election. The Board is not replaced at staggered intervals but is elected annually.

There is no provision in our bylaws or Articles that requires that a director must be a shareholder.

The directors are entitled to remuneration as shall from time to time be determined by the Board or by a committee to which the Board may delegate the
power  to  do  so.  Under  the  mandate  of  the  NGCC,  such  committee,  comprised  of  at  least  a  majority  of  independent  directors,  is  tasked  with  making
recommendations to the Board concerning director remuneration.

The CBCA provides that a director who is a party to, or who is a director or officer of, or has a material interest in, any person who is a party to a material
contract or transaction or proposed material contract or transaction with us must disclose to us the nature and extent of his or her interest at the time and in the
manner provided by the CBCA, or request that same be entered in the minutes of the meetings of the Board, even if such contract, in connection with our
normal business activity, does not require the approval of either the directors or the shareholders. At the request of the president or any director, the director
placed in a situation of conflict of interest must leave the meeting while the Board discusses the matter. The CBCA prohibits such a director from voting on
any resolution to approve the contract or transaction unless the contract or transaction:

•

•

relates primarily to his or her remuneration as our director, officer, employee or agent or as a director, officer, employee or agent of an affiliate of us;

is for indemnity or insurance for director's liability as permitted by the CBCA; or

72

•

is with our affiliate.

The CBCA provides that the Board may, on our behalf and without authorization of our shareholders:

•

•

•

borrow money upon our credit;

issue, reissue, sell or pledge our debt obligations;

give a guarantee on our behalf to secure performance of an obligation of any person; and

• mortgage, hypothecate, pledge or otherwise create a security interest in all or any of our property, owned or subsequently acquired, to secure any of our

obligations.

The  shareholders  have  the  ability  to  restrict  such  powers  through  our  Articles  or  bylaws  (or  through  a  unanimous  shareholder  agreement),  but  no  such
restrictions are in place.

The CBCA prohibits the giving of a guarantee to any of our shareholders, directors, officers or employees or of an affiliated corporation or to an associate of
any such person for any purpose or to any person for the purpose of or in connection with a purchase of a share issued or to be issued by us or our affiliates,
where there are reasonable grounds for believing that we are or, after giving the guarantee, would be unable to pay our liabilities as they become due, or the
realizable value of our assets in the form of assets pledged or encumbered to secure a guarantee, after giving the guarantee, would be less than the aggregate
of our liabilities and stated capital of all classes. These borrowing powers may be varied by our bylaws or Articles. However, our bylaws and Articles do not
contain any restrictions on or variations of these borrowing powers.

Pursuant  to  the  CBCA,  our  directors  manage  and  administer  our  business  and  affairs  and  exercise  all  such  powers  and  authority  as  we  are  authorized  to
exercise pursuant to the CBCA, the Articles and the bylaws. The general duties of our directors and officers under the CBCA are to act honestly and in good
faith  with  a  view  to  our  best  interests  and  to  exercise  the  care,  diligence  and  skill  that  a  reasonably  prudent  person  would  exercise  in  comparable
circumstances.  Any  breach  of  these  duties  may  lead  to  liability  to  us  and  our  shareholders  for  breach  of  fiduciary  duty.  In  addition,  a  breach  of  certain
provisions  of  the  CBCA,  including  the  improper  payment  of  dividends  or  the  improper  purchase  or  redemption  of  shares,  will  render  the  directors  who
authorized such action liable to account to us for any amounts improperly paid or distributed.

Our bylaws provide that the Board may, from time to time, appoint from amongst their number committees of the Board, and delegate to any such committee
any of the powers of the Board except those which pursuant to the CBCA a committee of the Board has no authority to exercise. As such, the Board has two
standing committees: the Audit Committee and the Nominating, Governance and Compensation Committee, or the NGCC.

Subject to the limitations provided by the CBCA, our bylaws provide that we shall, to the full extent provided by law, indemnify a director or an officer, a
former director or officer or a person who acts or acted at our request as a director or officer of a body corporate of which we are or were a shareholder or
creditor, and his or her heirs and legal representatives, against all costs, losses, charges and expenses, including an amount paid to settle an action or satisfy a
judgment, reasonably incurred by him or her in respect of any civil, criminal or administrative action or proceeding to which he or she is made a party by
reason of having been our director or officer or such body corporate, provided: (a) he or she acted in good faith in our best interests and (b) in the case of a
criminal or an administrative action or proceeding that is enforced by a monetary penalty, he or she had reasonable grounds to believe that his or her conduct
was lawful.

Our directors are authorized to indemnify from time to time any director or other person who has assumed or is about to assume in the normal course of
business any liability for us or for any corporation controlled by us and to secure such director or other person against any loss by the pledge of all or part of
our movable or immovable property through the creation of a hypothec or any other real right in all or part of such property or in any other manner.

We have also agreed to indemnify and save harmless our directors and senior corporate officers as well as the managing directors of our German subsidiary
pursuant to various Director and Officer Indemnification Agreements against certain charges, damages, awards, settlements, liabilities, interest, judgments,
fines, penalties, statutory obligations, professional fees and retainers and other expenses of whatever nature or kind, provided that any such costs, charges,
professional fees and other expenses are reasonable (collectively, "Expenses") and from and against all Expenses sustained or incurred by the indemnified
party as a result of serving as a director, officer or employee of the Company (or its subsidiary) in respect of any act, matter, deed or thing whatsoever made,
done, committed, permitted, omitted or acquiesced in by the indemnified party as a director, officer or employee of the Company (or its subsidiary). The form
of Director and Officer Indemnification Agreement has been furnished to the SEC as Exhibit 99.1 to our Report on Form 6-K dated October 21, 2016.

Share Capitalization

Our  authorized  share  capital  structure  consists  of  an  unlimited  number  of  shares  of  the  following  classes  (all  classes  are  without  nominal  or  par  value):
Common Shares; and first preferred shares (the "First Preferred Shares") and second preferred shares (the "Second Preferred Shares" and, together with the
First  Preferred  Shares,  the  "Preferred  Shares"),  both  issuable  in  series.  As  at  March  27,  2018,  there  were  approximately  16.4  million  Common  Shares
outstanding.  No  Preferred  Shares  have  been  issued  to  date.  We  have  also  issued  warrants  to  acquire  Common  Shares  in  connection  with  certain  equity
financings.

Common Shares

The holders of the Common Shares are entitled to one vote for each Common Share held by them at all meetings of shareholders, except meetings at which
only shareholders of a specified class of shares are entitled to vote. In addition, the holders are entitled to receive dividends if, as and when declared by our
Board of Directors on the Common Shares. Finally, the holders of the Common Shares are entitled to receive our remaining property upon any liquidation,
dissolution  or  winding-up  of  our  affairs,  whether  voluntary  or  involuntary.  Shareholders  have  no  liability  to  further  capital  calls  as  all  shares  issued  and
outstanding are fully paid and non-assessable.

Preferred Shares

The First and Second Preferred Shares are issuable in series with rights and privileges specific to each class. The holders of Preferred Shares are generally not
entitled to receive notice of or to attend or vote at meetings of shareholders. The holders of First Preferred Shares are entitled to preference and priority to any
participation of holders of Second Preferred Shares, Common Shares or shares of any other class of shares of our share capital ranking junior to the First
Preferred Shares with respect to dividends and, in the event of our liquidation, the distribution of our property upon our dissolution or winding-up, or the
distribution of all or part of our assets among the shareholders, to an amount equal to the value of the consideration paid in respect of such shares outstanding,
as credited to our issued and paid-up share capital, on an equal basis, in proportion to the amount of their respective claims in regard to such shares held by
them. The holders of Second Preferred Shares are entitled to preference and priority to any participation of holders of Common Shares or shares of any other
class of shares of our share capital ranking junior to the Second Preferred Shares with respect to dividends and, in the event of our liquidation, the distribution
of our property upon our dissolution or winding-up, or the distribution of all or part of our assets among the shareholders, to an amount equal to the value of
the consideration paid in respect of such shares outstanding, as credited to our issued and paid-up share capital, on an equal basis, in proportion to the amount
of their respective claims in regard to such shares held by them.

Our Board of Directors may, from time to time, provide for additional series of Preferred Shares to be created and issued, but the issuance of any Preferred
Shares is subject to the general duties of the directors under the CBCA to act honestly and in good faith with a view to our best interests and to exercise the
care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances.

Warrants

For a description of our Warrants, see note 14 - warrant liability, to the audited consolidated financial statements included in Item 18 of this Annual Report on
Form 20-F.

Shareholder Actions

The CBCA provides that our shareholders may, with leave of a court, bring an action in our name and on our behalf for the purpose of prosecuting, defending
or discontinuing an action on our behalf. In order to grant leave to permit such an action, the CBCA provides that the court must be satisfied that our directors
were given adequate notice of the application, the shareholder is acting in good faith and that it appears to be in our best interests that the action be brought.

Shareholder Rights Plan

Our  Board  of  Directors  adopted  a  shareholder  rights  plan  on  March  29,  2016  (the  "Rights  Plan").  Our  shareholders  approved,  ratified  and  confirmed  the
Rights Plan at our Annual Meeting of Shareholders on May 10, 2016.

Objectives and Background of the Shareholder Rights Plan

The fundamental objectives of the Rights Plan are to provide adequate time for our Board and shareholders to assess an unsolicited take-over bid for us, to
provide  the  Board  with  sufficient  time  to  explore  and  develop  alternatives  for  maximizing  shareholder  value  if  a  take-over  bid  is  made,  and  to  provide
shareholders with an equal opportunity to participate in a take-over bid.

74

The Rights Plan encourages a potential acquiror who makes a take-over bid to proceed either by way of a "Permitted Bid", as described below, which requires
a take-over bid to satisfy certain minimum standards designed to promote fairness, or with the concurrence of our Board. If a take-over bid fails to meet these
minimum standards and the Rights Plan is not waived by the Board, the Rights Plan provides that holders of Common Shares, other than the acquiror, will be
able to purchase additional Common Shares at a significant discount to market, thus exposing the person acquiring Common Shares to substantial dilution of
its holdings.

Summary of the Rights Plan

The following is a summary of the principal terms of the Rights Plan, which summary is qualified in its entirety by reference to the terms thereof. Capitalized
terms not otherwise defined in this summary shall have the meaning ascribed to such terms in the Shareholder Rights Plan Agreement which sets forth the
Rights Plan. The Rights Plan is incorporated by reference as Exhibit 2.1 to this Annual Report on Form 20-F.

For the purposes of this summary and as set out in the Rights Plan, the term "NI 62-104" refers to National Instrument 62-104-Take-Over Bids and Issuer
Bids adopted by the Canadian securities regulatory authorities, as now in effect or as the same may from time to time be amended, re-enacted or replaced and
including for greater certainty any successor instrument thereto.

Operation of the Rights Plan

Pursuant to the terms of the Rights Plan, one right was issued in respect of each common share outstanding at 5:01 p.m. on March 29, 2016 (the "Record
Time"). In addition, we will issue one right for each additional Common Share issued after the Record Time and prior to the earlier of the Separation Time (as
defined  below)  and  the  Expiration  Time  (as  defined  below).  The  rights  have  an  initial  exercise  price  equal  to  the  Market  Price  (as  defined  below)  of  the
Common Shares as determined at the Separation Time, multiplied by five, subject to certain anti-dilution adjustments (the "Exercise Price"), and they are not
exercisable  until  the  Separation  Time.  Upon  the  occurrence  of  a  Flip-in  Event  (as  defined  below),  each  right  will  entitle  the  holder  thereof,  other  than  an
Acquiring Person or any other person whose rights are or become void pursuant to the provisions of the Rights Plan, to purchase from us, effective at the
close of business on the eighth trading day after the Stock Acquisition Date (as defined below), upon payment to us of the Exercise Price, Common Shares
having an aggregate Market Price equal to twice the Exercise Price on the date of consummation or occurrence of such Flip-in Event, subject to certain anti-
dilution adjustments.

Definition of Market Price

Market Price is generally defined in the Rights Plan, on any given day on which a determination must be made, as the volume weighted average trading price
of the Common Shares for the five consecutive trading days (i.e. days on which the TSX or another stock exchange or national securities quotation system on
which the Common Shares are traded (including for greater certainty, each of the Nasdaq Global Select Market, the Nasdaq Global Market and the Nasdaq
Capital Market) is open for the transaction of business, subject to certain exceptions), through and including the trading day immediately preceding such date
of determination, subject to certain exceptions.

Trading of Rights

Until the Separation Time (or the earlier termination or expiration of the rights), the rights trade together with the Common Shares and are represented by the
same  share  certificates  as  the  Common  Shares  or  an  entry  in  our  securities  register  in  respect  of  any  outstanding  Common  Shares.  From  and  after  the
Separation Time and prior to the Expiration Time, the rights are evidenced by rights certificates and trade separately from the Common Shares. The rights do
not carry any of the rights attaching to the Common Shares such as voting or dividend rights.

Separation Time

The  rights  will  separate  from  the  Common  Shares  to  which  they  are  attached  and  become  exercisable  at  the  time  (the  "Separation  Time")  of  the  close  of
business on the eighth business day after the earliest to occur of:

1.

2.

the first date (the "Stock Acquisition Date") of a public announcement of facts indicating that a person has become an Acquiring Person; and

the date of the commencement of, or first public announcement of the intention of any person (other than us or any of our subsidiaries) to commence
a take-over bid or a share exchange bid for more than 20% of our outstanding Common Shares other than a Permitted Bid or a Competing Permitted
Bid (as defined below), so long as such take-over bid continues to satisfy the requirements of a Permitted Bid or a Competing Permitted Bid, as the
case may be.

75

The Separation Time can also be such later time as may from time to time be determined by the Board, provided that if any such take-over bid expires, or is
canceled, terminated or otherwise withdrawn prior to the Separation Time, without securities deposited thereunder being taken up and paid for, it shall be
deemed never to have been made and if the Board determines to waive the application of the Rights Plan to a particular Flip-in Event, the Separation Time in
respect of such Flip-in Event shall be deemed never to have occurred.

From and after the Separation Time and prior to the Expiration Time, each right entitles the holder thereof to purchase one Common Share upon payment of
the Exercise Price to us.

Flip-in Event

The acquisition by a person (an "Acquiring Person"), including others acting jointly or in concert with such person, of more than 20% of the outstanding
Common Shares, other than by way of a Permitted Bid, a Competing Permitted Bid or in certain other limited circumstances described in the Rights Plan, is
referred to as a "Flip-in Event".

In the event that, prior to the Expiration Time, a Flip-in Event that has not been waived occurs (see "Waiver and Redemption" below), each right (other than
those held by or deemed to be held by the Acquiring Person) will thereafter entitle the holder thereof, effective as at the close of business on the eighth trading
day after the Stock Acquisition Date, to purchase from us, upon payment of the Exercise Price and otherwise exercising such right in accordance with the
terms of the Rights Plan, that number of Common Shares having an aggregate Market Price on the date of consummation or occurrence of the Flip-in Event
equal to twice the Exercise Price, for an amount in cash equal to the Exercise Price (subject to certain anti-dilution adjustments described in the Rights Plan).

A bidder may enter into Lock-up Agreements with our shareholders ("Locked-up Persons") who are not affiliates or associates of the bidder and who are not,
other than by virtue of entering into such agreement, acting jointly or in concert with the bidder, whereby such shareholders agree to tender their Common
Shares to the take-over bid (the "Lock-up Bid") without the bidder being deemed to beneficially own the Common Shares deposited pursuant to the Lock-up
Bid. Any such agreement must include a provision that permits the Locked-up Person to withdraw the Common Shares to tender to another take-over bid or
to support another transaction that will either provide greater consideration to the shareholder than the Lock-up Bid or provide for a right to sell a greater
number  of  shares  than  the  Lock-up  Bid  contemplates  (provided  that  the  Lock-up  Agreement  may  require  that  such  greater  number  exceed  the  number  of
shares under the Locked-up Bid by a specified percentage not to exceed 7%).

The  Lock-up  Agreement  may  require  that  the  consideration  under  the  other  transaction  exceed  the  consideration  under  the  Lock-up  Bid  by  a  specified
amount. The specified amount may not be greater than 7%. For greater certainty, a Lock-up Agreement may contain a right of first refusal or require a period
of delay (or other similar limitation) to give a bidder an opportunity to match a higher price in another transaction as long as the limitation does not preclude
the exercise by the Locked-up Person of the right to withdraw the Common Shares during the period of the other take-over bid or transaction.

The Rights Plan requires that any Lock-up Agreement be made available to us and the public. The definition of Lock-up Agreement also provides that under a
Lock-up Agreement, no "break up" fees, "topping" fees, penalties, expenses or other amounts that exceed in aggregate the greater of (i) 2.5% of the price or
value of the aggregate consideration payable under the Lock-up Bid, and (ii) 50% of the amount by which the price or value of the consideration received by
a Locked-up Person under another take-over bid or transaction exceeds what such Locked-up Person would have received under the Lock-up Bid, can be
payable  by  such  Locked-up  Person  if  the  Locked-up  Person  fails  to  deposit  or  tender  Common  Shares  to  the  Lock-up  Bid  or  withdraws  Common  Shares
previously tendered thereto in order to deposit such Common Shares to another take-over bid or support another transaction.

Permitted Bid Requirements

The requirements of a Permitted Bid include the following:

1.

2.

3.

the take-over bid must be made by means of a take-over bid circular;

the take-over bid must be made to all holders of Common Shares wherever resident, on identical terms and conditions, other than the bidder;

the take-over bid must not permit Common Shares tendered pursuant to the bid to be taken up or paid for:

a)

prior  to  the  close  of  business  on  a  date  that  is  not  less  than  105  days  following  the  date  of  the  relevant  take-over  bid  or  such  shorter
minimum period that a take-over bid (that is not exempt from any of the requirements of

76

Division 5 (Bid Mechanics of NI 62-104)) must remain open for deposits of securities thereunder, in the applicable circumstances at such
time, pursuant to NI 62-104;

b)

then only if at the close of business on the date Common Shares (and/or "Convertible Securities", as defined in the Rights Plan) are first
taken up or paid for under such take-over bid, outstanding Common Shares and Convertible Securities held by shareholders other than any
other  Acquiring  Person,  the  bidder,  the  bidder’s  affiliates  or  associates,  persons  acting  jointly  or  in  concert  with  the  bidder  and  any
employee benefit plan, deferred profit-sharing plan, stock participation plan or trust for the benefit of our employees or the employees of
any of our subsidiaries, unless the beneficiaries of such plan or trust direct the manner in which the Common Shares are to be voted or
direct whether the Common Shares are to be tendered to a take-over bid (collectively, "Independent Shareholders") that represent more than
50% of the aggregate of (I) then outstanding Common Shares and (II) Common Shares issuable upon the exercise of Convertible Securities,
have been deposited or tendered pursuant to the take-over bid and not withdrawn;

the take-over bid must allow Common Shares and/or Convertible Securities to be deposited or tendered pursuant to such take-over bid, unless such
take-over bid is withdrawn, at any time prior to the close of business on the date Common Shares and/or Convertible Securities are first taken up or
paid for under the take-over bid;

the take-over bid must allow Common Shares and/or Convertible Securities to be withdrawn until taken up and paid for; and

in the event the requirement set forth in clause 3.b) above is satisfied, the bidder must make a public announcement of that fact and the take-over bid
must remain open for deposits and tenders of Common Shares for not less than ten days from the date of such public announcement.

4.

5.

6.

A Permitted Bid need not be a bid for all outstanding Common Shares not held by the bidder, i.e., a Permitted Bid may be a partial bid. The Rights Plan also
allows a competing Permitted Bid (a "Competing Permitted Bid") to be made while a Permitted Bid is in existence. A Competing Permitted Bid must satisfy
all the requirements of a Permitted Bid other than the requirement set out in clause 3.a) above and must not permit Common Shares tendered or deposited
pursuant to the bid to be taken up or paid for prior to the close of business on the last day of the minimum initial deposit period that such take-over bid must
remain  open  for  deposits  of  securities  thereunder  pursuant  to  NI  62-104  after  the  date  of  the  take-over  bid  constituting  the  Competing  Permitted  Bid;
provided, however, that a take-over bid that has qualified as a Competing Permitted Bid shall cease to be a Competing Permitted Bid at any time and as soon
as  such  time  as  when  such  take-over  bid  ceases  to  meet  any  or  all  of  the  foregoing  provisions  of  the  definition  of  "Competing  Permitted  Bid"  and  any
acquisition of Common Shares and/or Convertible Securities made pursuant to such take-over bid that qualified as a Competing Permitted Bid, including any
acquisition  of  Common  Shares  and/or  Convertible  Securities  made  before  such  take-over  bid  ceased  to  be  a  Competing  Permitted  Bid,  will  not  be  a
"Permitted Bid Acquisition" (as defined in the Rights Plan).

Waiver and Redemption

The Board may, prior to the occurrence of a Flip-in Event, waive the dilutive effects of the Rights Plan in respect of, among other things, a particular Flip-in
Event resulting from a take-over bid made by way of a take-over bid circular to all holders of our Common Shares. In such an event, such waiver shall also be
deemed to be a waiver in respect of any other Flip-in Event occurring under a take-over bid made by way of a take-over bid circular to all holders of Common
Shares prior to the expiry of the first mentioned take-over bid.

The Board may, with the approval of a majority of Independent Shareholders (or, after the Separation Time has occurred, holders of rights, other than rights
which are void pursuant to the provisions of the Rights Plan or which, prior to the Separation Time, are held otherwise than by Independent Shareholders), at
any time prior to the occurrence of a Flip-in Event which has not been waived, elect to redeem all, but not less than all, of the then outstanding rights at a
price of CAN$0.00001 each, appropriately adjusted as provided in the Rights Plan (the "Redemption Price").

Where a take-over bid that is not a Permitted Bid or Competing Permitted Bid is withdrawn or otherwise terminated after the Separation Time has occurred
and prior to the occurrence of a Flip-in Event, the Board may elect to redeem all the outstanding rights at the Redemption Price without the consent of the
holders of the Common Shares or the rights and reissue rights under the Rights Plan to holders of record of Common Shares immediately following such
redemption. Upon the rights being so redeemed and reissued, all the provisions of the Rights Plan will continue to apply as if the Separation Time had not
occurred, and the Separation Time will be deemed not to have occurred and we shall be deemed to have issued replacement rights to the holders of its then
outstanding Common Shares.

77

Amendment to the Rights Plan

The Rights Plan may be amended to correct any clerical or typographical error or to make such changes as are required to maintain the validity of the Rights
Plan as a result of any change in any applicable legislation, regulations or rules thereunder, without the approval of the holders of the Common Shares or
rights. Prior to the Separation Time, we may, with the prior consent of the holders of Common Shares, amend, vary or delete any of the provisions of the
Rights  Plan  in  order  to  effect  any  changes  which  the  Board,  acting  in  good  faith,  considers  necessary  or  desirable.  We  may,  with  the  prior  consent  of  the
holders of rights, at any time after the Separation Time and before the Expiration Time, amend, vary or delete any of the provisions of the Rights Plan.

Protection Against Dilution

The Exercise Price, the number and nature of securities which may be purchased upon the exercise of rights and the number of rights outstanding are subject
to  adjustment  from  time  to  time  to  prevent  dilution  in  the  event  of  stock  dividends,  subdivisions,  consolidations,  reclassifications  or  other  changes  in  the
outstanding Common Shares, pro rata distributions to holders of Common Shares and other circumstances where adjustments are required to appropriately
protect the interests of the holders of rights.

Fiduciary Duty of Board

The Rights Plan will not detract from or lessen the duty of the Board to act honestly and in good faith with a view to our best interests and the best interests of
our  shareholders.  The  Board  will  continue  to  have  the  duty  and  power  to  take  such  actions  and  make  such  recommendations  to  our  shareholders  as  are
considered appropriate.

Exemptions for Investment Advisors

Fund managers, investment advisors (for fully-managed accounts), trust companies (acting in their capacities as trustees and administrators), statutory bodies
whose business includes the management of funds, and administrators of registered pension plans are exempt from triggering a Flip-in Event, provided that
they are not making, or are not part of a group making, a take-over bid.

Term

The  Rights  Plan  will  expire  (the  "Expiration  Time")  at  the  close  of  business  on  the  date  on  which  the  first  annual  meeting  of  our  shareholders  following
March  29,  2019  (being  the  third  anniversary  of  the  Record  Time)  is  held;  provided,  however,  that  if  our  Independent  Shareholders  approve  a  resolution
confirming the Rights Plan at or prior to the 2019 annual meeting of our shareholders, Expiration Time shall mean the close of business on the date on which
the first annual meeting of our shareholders following March 29, 2022 (being the sixth anniversary of the Record Time) is held.

Action Necessary to Change Rights of Shareholders

In order to change the rights of our shareholders, we would need to amend our Articles to effect the change. Such an amendment would require the approval
of holders of two-thirds of the issued and outstanding shares cast at a duly called special meeting. For certain amendments, a shareholder is entitled under the
CBCA to dissent in respect of such a resolution amending the Articles and, if the resolution is adopted and we implement such changes, demand payment of
the fair value of its shares.

Disclosure of Share Ownership

In general, under applicable securities regulation in Canada, a person or company who beneficially owns, or who directly or indirectly exercises control or
direction over voting securities of a reporting issuer, voting securities of an issuer or a combination of both, carrying more than ten percent of the voting rights
attached  to  all  the  issuer's  outstanding  voting  securities  is  an  insider  and  must,  within  ten  days  of  becoming  an  insider,  file  a  report  in  the  required  form
effective the date on which the person became an insider, disclosing any direct or indirect beneficial ownership of, or control or direction over, securities of
the reporting issuer.

Additionally, securities regulation in Canada provides for the filing of a report by an insider of a reporting issuer whose holdings change, which report must
be filed within five days from the day on which the change takes place.

Section  13  of  the  Exchange  Act  imposes  reporting  requirements  on  persons  who  acquire  beneficial  ownership  (as  such  term  is  defined  in  the  Rule  13d-3
under the Exchange Act) of more than five percent of a class of an equity security registered under Section 12 of the Exchange Act. Our Common Shares are
so  registered.  In  general,  such  persons  must  file,  within  ten  days  after  such  acquisition,  a  report  of  beneficial  ownership  with  the  SEC  containing  the
information prescribed by the regulations under Section 13 of the Exchange Act. This information is also required to be sent to the issuer of the securities and
to each exchange where the securities are traded.

78

Meeting of Shareholders

An annual meeting of shareholders is held each year for the purpose of considering the financial statements and reports, electing directors, appointing auditors
and fixing or authorizing the Board to fix their remuneration and for the transaction of other business as may properly come before a meeting of shareholders.
Any annual meeting may also constitute a special meeting to take cognizance and dispose of any matter of which a special meeting may take cognizance and
dispose. Under the bylaws, our Chief Executive Officer or our President has the power to call a meeting of shareholders.

The CBCA provides that the holders of not less than 5% of our outstanding voting shares may requisition our directors to call a meeting of shareholders for
the  purpose  stated  in  the  requisition.  Except  in  limited  circumstances,  including  where  a  meeting  of  shareholders  has  already  been  called  and  a  notice  of
meeting already given or where it is clear that the primary purpose of the requisition is to redress a personal grievance against us or our directors, officers or
shareholders, our directors, on receipt of such requisition, must call a meeting of shareholders. If the directors fail to call a meeting of shareholders within
twenty-one days after receiving the requisition, any shareholder who signed the requisition may call the meeting of shareholders and, unless the shareholders
resolve otherwise at the meeting, we shall reimburse the shareholders for the expenses reasonably incurred by them in requisitioning, calling and holding the
meeting of shareholders.

The CBCA also provides that, except in limited circumstances, a resolution in writing signed by all of the shareholders entitled to vote on that resolution at a
meeting of shareholders is as valid as if it had been passed at a meeting of shareholders.

A quorum of shareholders is present at an annual or special meeting of shareholders, regardless of the number of persons present in person at the meeting, if
the holder(s) of shares representing at least 10% of the outstanding voting shares at such meeting are present in person or represented in accordance with our
bylaws. In the case where the CBCA, our Articles or our bylaws require or permit the vote by class of holders of a given class of shares of our share capital,
the quorum at any meeting will be one or more persons representing 10% of the outstanding shares of such class.

Notice of the time and place of each annual or special meeting of shareholders must be given not less than 21 days, nor more than 50 days, before the date of
each meeting to each director, to the auditor and to each shareholder entitled to vote thereat. If the address of any shareholder, director or auditor does not
appear in our books, the notice may be sent to such address as the person sending the notice may consider to be most likely to reach such shareholder, director
or auditor promptly. Every person who, by operation of the CBCA, transfers or by any other means whatsoever, becomes entitled to any share, shall be bound
by every notice given in respect of such share which, prior to the entry of his or her name and address on our register, is given to the person whose name
appears on the register at the time such notice is sent. Notice of meeting of shareholders called for any other purpose other than consideration of the financial
statements and auditor's report, election of directors and reappointment of the incumbent auditor, must state the nature of the business in sufficient detail to
permit the shareholder to form a reasoned judgment on and must state the text of any special resolution or bylaw to be submitted to the meeting.

Our bylaws include an advance notice provision (the "Advance Notice Requirement"). The Advance Notice Requirement applies in certain circumstances
where nominations of persons for election to the Board of Directors are made by our shareholders other than pursuant to: (a) a requisition of a meeting made
pursuant to the provisions of the CBCA; or (b) a shareholder proposal made pursuant to the provisions of the CBCA.

Among other things, the Advance Notice Requirement fixes a deadline by which shareholders must submit a notice of director nominations to us prior to any
annual or special meeting of shareholders where directors are to be elected and sets forth the information that a shareholder must include in the notice for it to
be valid. In the case of an annual meeting of shareholders, we must be given not less than 30 nor more than 65 days' notice prior to the date of the annual
meeting; provided, however, that in the event that the annual meeting is to be held on a date that is less than 50 days after the date on which the first public
announcement of the date of the annual meeting was made, notice may be made not later than the close of business on the 10th day following such public
announcement. In the case of a special meeting of shareholders (which is not also an annual meeting), we must be given notice not later than the close of
business on the 15th day following the day on which the first public announcement of the date of the special meeting was made.

The Board of Directors may, in its sole discretion, waive any requirement of the Advance Notice Requirement.

Limitations on Right to Own Securities

Neither Canadian law nor our Articles or bylaws limit the right of a non-resident to hold or vote our Common Shares, other than as provided in the Investment
Canada Act (the "Investment Act").

The Investment Act requires any person that is a "non-Canadian" (as defined in the Investment Act) who acquires "control" (as defined in the Investment Act)
of an existing Canadian business to file either a pre-closing application for review or a post-closing notification with Industry Canada.

79

On March 25, 2015, the Canadian government announced new Investment Act regulations that changed the thresholds for determining when an acquisition of
control of a Canadian business is a reviewable transaction (from an asset value-based test to an enterprise value-based test, in most cases). As of April 24,
2015, when amendments to the Investment Act and the regulations come into force, the threshold for review of a direct acquisition of control of a non-cultural
Canadian business by a World Trade Organization member country investor is an enterprise value of assets that exceeds CAN$600 million. The enterprise
value review threshold will remain at CAN$600 million for two years, before increasing to CAN$800 million for the following two years, and then to CAN$1
billion. For purposes of a publicly traded company, the "enterprise value" of the assets of the Canadian business is equal to the market capitalization of the
entity, plus its liabilities (excluding its operating liabilities), minus its cash and cash equivalents.

As such, under the Investment Act, the acquisition of control of us (either through the acquisition of our Common Shares or all or substantially all our assets)
by a non-Canadian who is a World Trade Organization member country investor, including a U.S. investor, would be reviewable only if the enterprise value
of our assets exceeds the specified threshold for review.

Where the acquisition of control is a reviewable transaction, the Investment Act generally prohibits the implementation of the reviewable transaction unless,
after review, the relevant Minister is satisfied or deemed to be satisfied that the acquisition is likely to be of net benefit to Canada.

The acquisition of a majority of the voting interests of an entity is deemed to be acquisition of "control" of that entity. The acquisition of less than a majority
but one-third or more of the total number of votes attached to all of the voting shares of a corporation or of an equivalent undivided ownership interest in the
total number of votes attached to all of the voting shares of the corporation is presumed to be an acquisition of control of that corporation unless it can be
established that, on the acquisition, the corporation is not controlled in fact by the acquiror through the ownership of voting shares. The acquisition of less
than one-third of the total number of votes attached to all of the voting shares of a corporation is deemed not to be acquisition of control of that corporation
subject to certain discretionary rights relative to investments involving state owned enterprises. Other than in connection with a "national security" review,
discussed below, certain transactions in relation to our Common Shares would be exempt from the Investment Act including:

•

•

•

 the acquisition of our Common Shares by a person in the ordinary course of that person's business as a trader or dealer in securities;

the  acquisition  or  control  of  us  in  connection  with  the  realization  of  security  granted  for  a  loan  or  other  financial  assistance  and  not  for  any  purpose
related to the provisions of the Investment Act; and

the acquisition or control of us by reason of an amalgamation, merger, consolidation or corporate reorganization following which the ultimate direct or
indirect control in fact of us, through the ownership of our voting interests, remains unchanged.

Under the national security regime in the Investment Act, review on a discretionary basis may also be undertaken by the federal government in respect of a
much broader range of investments by a non-Canadian to "acquire, in whole or in part, or to establish an entity carrying on all or any part of its operations in
Canada". The relevant test is whether such an investment by a non-Canadian could be "injurious to national security". The Minister of Innovation, Science
and  Economic  Development  has  broad  discretion  to  determine  whether  an  investor  is  a  non-Canadian  and  therefore  may  be  subject  to  national  security
review. Review on national security grounds is at the discretion of the federal government and may occur on a pre or post-closing basis.

There is no law, governmental decree or regulation in Canada that restricts the export or import of capital, or which would affect the remittance of dividends
or other payments by us to non-resident holders of our Common Shares, other than withholding tax requirements.

Material contracts

Other than as disclosed herein under "Shareholder Rights Plan" and below, and except for contracts entered into in the ordinary course of business, there are
no material contracts to which we or any of our subsidiaries is a party.

Strongbridge License Agreement

On  January  16,  2018,  the  Company,  through  AEZS  Germany,  entered  into  a  license  and  assignment  agreement  Strongbridge  License  Agreement  with
Strongbridge, to carry out development, manufacturing, registration and commercialization of Macrilen™ (macimorelin) in the United States and Canada.

The Company received an upfront cash payment of $24,000,000 from Strongbridge, and, for as long as Macrilen™ (macimorelin) is patent-protected, the
Company will be entitled to a 15% royalty on net sales up to $75,000,000 and an 18% royalty on net sales above $75,000,000. Following the end of patent
protection in United States or Canada for Macrilen™ (macimorelin), the Company

80

will be entitled to a 5% royalty on net sales in that country. In addition, the Company will also receive one-time payments from Strongbridge following the
first achievement of the following commercial milestone events:

•

•

•

•

•

$4,000,000 on achieving $25,000,000 annual net sales,

$10,000,000 on achieving $50,000,000 annual net sales,

$20,000,000 on achieving $100,000,000 annual net sales,

$40,000,000 on achieving $200,000,000 annual net sales, and

$100,000,000 on achieving $500,000,000 annual net sales.

Upon approval by the FDA of a pediatric indication for Macrilen™ (macimorelin), the Company will receive a one-time milestone payment of $5,000,000
from Strongbridge.

Strongbridge will fund 70% of the costs of a worldwide pediatric development program to be run by the Company with customary oversight from a joint
steering  committee.  The  joint  steering  committee  will  be  comprised  of  four  persons,  two  of  whom  will  be  appointed  by  each  of  Strongbridge  and  the
Company.

The Strongbridge License Agreement will expire at the end of a defined royalty period in each country of the United States and Canada, at which time the
license that the Company granted to Strongbridge will become irrevocable, fully paid-up, perpetual and royalty-free in such country. Strongbridge has the
right to terminate the Strongbridge License Agreement if there is a safety concern related to Macrilen™ (macimorelin), withdrawal of regulatory approval for
Macrilen™  (macimorelin)  in  the  U.S.  believed  to  be  permanent,  two  hundred  and  seventy  (270)  days'  prior  written  notice,  or  if  the  Company  commits  a
material  breach  of  any  term  of  the  Strongbridge  License  Agreement  that  it  fails  to  cure  within  90  days  after  receiving  written  notice  of  the  breach.  The
Company has the right to terminate the Strongbridge License Agreement if Strongbridge commits a material breach of any term of the Strongbridge License
Agreement that it fails to cure within 90 days after receiving written notice of the breach. If the breach relates to Canada then the Company shall only have
the right to terminate the Strongbridge License Agreement in relation to Canada. If the breach relates to the United States, then the Company shall have the
right to terminate the Strongbridge License Agreement in its entirety.

The Strongbridge License Agreement contains customary provisions related to, among other things, confidentiality and non-disclosure, representations and
warranties, indemnity and dispute resolution. The Strongbridge License Agreement is governed by the laws of the State of New York, United States.

The Strongbridge License Agreement is incorporated by reference as Exhibit 4.2 to this Annual Report on Form 20-F.

Sinopharm Agreements

On December 1, 2014, we entered into an exclusive master collaboration agreement ("Master Collaboration Agreement"), a technology transfer and technical
assistance  agreement  ("Tech  Transfer  Agreement")  and  a  license  agreement  ("Sinopharm  License  Agreement")  with  Sinopharm  A-Think  Pharmaceuticals
Co.,  Ltd.  ("Sinopharm")  for  the  development,  manufacture  and  commercialization  of  Zoptrex™  in  all  human  uses,  in  the  People's  Republic  of  China,
including Hong Kong and Macau (collectively, the "Sinopharm Territory"). Under the terms of the Tech Transfer Agreement, Sinopharm made a one-time,
non-refundable payment of $1,101,000 ("Transfer Fee") to us for the transfer of technical documentation and materials, know-how and technical assistance
services.  We  will  be  entitled  to  receive  additional  consideration  upon  achieving  certain  milestones,  including  the  occurrence  of  certain  regulatory  and
commercial  events  in  the  Sinopharm  Territory.  Furthermore,  we  will  be  entitled  to  royalties  on  future  net  sales  of  Zoptrex™  in  the  Sinopharm  Territory.
Sinopharm will be responsible for the development, production, registration and commercialization of Zoptrex™ in the Sinopharm Territory.

Sinopharm is required to use commercially reasonable efforts to develop, manufacture and commercialize Zoptrex™ in the Sinopharm Territory, in order to
maximize  the  net  sales  derived  from  Zoptrex™  during  the  royalty  term  of  the  Sinopharm  License  Agreement.  In  particular,  Sinopharm  is  required  to  use
commercially reasonable efforts to: (i) develop Zoptrex™ for the indication of endometrial cancer in the Sinopharm Territory in accordance with an agreed
development plan and not to terminate, suspend, halt or delay development, unless there are substantial safety, efficacy, commercial or regulatory reasons for
doing so; (ii) apply for and obtain all required regulatory approvals in the Sinopharm Territory following successful completion of all appropriate clinical
studies; (iii) make the first commercial sale of Zoptrex™ in the Sinopharm Territory within a specified period of time following the approval of Zoptrex™ for
endometrial  cancer;  (iv)  maintain  an  adequate  sales  force  and  provide  for  relevant  staff  to  manage  the  pre-  and  post-launch  activities  required  to
commercialize Zoptrex™ in the Sinopharm Territory; and (v) seek to maximize sales of Zoptrex™ in the Sinopharm Territory. Sinopharm’s failure to use
commercially reasonable efforts to develop, manufacture and commercialize Zoptrex™ would be a material breach of the Sinopharm License Agreement.

81

The Sinopharm License Agreement imposes on Sinopharm the responsibility for marketing, promoting and selling Zoptrex™ in the Sinopharm Territory after
all regulatory approvals for commercial sale have been obtained, including pre-launch and post-launch marketing, promoting, conducting market research,
distributing,  offering  to  commercially  sell  and  commercially  selling  Zoptrex™,  importing,  exporting  or  transporting  Zoptrex™  for  commercial  sale,
conducting  medical  education  activities,  conducting  clinical  studies  that  are  not  required  to  obtain  or  maintain  regulatory  approval  of  Zoptrex™  for  an
indication, which may include epidemiological studies, modeling and pharmacoeconomic studies, conducting post-marketing surveillance studies, conducting
investigator sponsored studies and health economics studies and regulatory affairs.

The Sinopharm License Agreement will expire at the end of a defined royalty period, at which time the license that we granted to Sinopharm will become a
fully paid-up, perpetual license. Sinopharm has the right to terminate the Sinopharm License Agreement if there are material safety, efficacy, commercial or
regulatory reasons for doing so; if we commit a material breach of any term of the Sinopharm License Agreement that we fail to cure within 90 days after
receiving written notice of the breach; if we file or institute bankruptcy, reorganization, liquidation or receivership proceedings; or if we assign a substantial
portion  of  our  assets  for  the  benefit  of  our  creditors.  If  Sinopharm  has  the  right  to  terminate  because  a  third  party  institutes  involuntary  bankruptcy
proceedings against us, we will have 90 days to obtain the dismissal of the proceedings, during which time, Sinopharm may not terminate the Agreement.

We have the right to terminate the Sinopharm License Agreement if Sinopharm commits a material breach of any term of the Sinopharm License Agreement
that it fails to cure within 90 days after receiving written notice of the breach; if it files or institutes bankruptcy, reorganization, liquidation or receivership
proceedings, or if it assigns a substantial portion of its assets for the benefit of its creditors. If we have the right to terminate because a third-party institutes
involuntary  bankruptcy  proceedings  against  Sinopharm,  it  will  have  90  days  to  obtain  the  dismissal  of  the  proceedings,  during  which  time,  we  may  not
terminate the Agreement.

The Sinopharm License Agreement contains customary provisions related to, among other things, our oversight of Sinopharm's commercialization efforts,
intellectual property, pharmacovigilance, confidentiality and non-disclosure, representations and warranties, indemnity and dispute resolution. The Sinopharm
License Agreement is governed by the laws of Hong Kong.

We do not anticipate significant revenues from the Sinopharm License Agreement in the future other than the amoritzation of the remaining deferred revenue.

The Master Collaboration Agreement, the Sinopharm License Agreement and the Tech Transfer Agreement are incorporated by reference as Exhibits 4.7, 4.8
and 4.9 to this Annual Report on Form 20-F.

Employment and Service Agreements

We had, or one of our subsidiaries had, entered into an employment agreement and, in some cases, a change of control agreement with each of our Named
Executive Officers, except for Ms. Genevieve Lemaire, who provides services to us as a contractor and not as an employee. We terminated the employment of
Mr. Dodd for cause on July 20, 2017, we terminated the employment of Mr. Theodore on July 28, 2017 and we terminated the employment of Mr. Dinges on
November 3, 2017. Mr. Whitnell resigned effective December 7, 2017. We terminated Dr. Sachse’s employment on January 17, 2018.

We entered into an employment agreement and a change of control agreement with Michael V. Ward, Chief Executive Officer, effective as of October 1, 2017
(the "Employment Agreement"). The Employment Agreement provides that we will pay Mr. Ward (the "Executive") an initial base salary of $250,000 and an
annual cash bonus, if our financial results and position justify payment of a bonus and subject to the determination and approval of the NGCC and our Board.
Additionally, the Executive will be eligible to receive long-term incentive grants in the form of stock options, which will be reviewed annually in accordance
with our policies. Under the terms of the Employment Agreement, Mr. Ward's base salary increased to $325,000, upon approval of Macrilen™ (macimorelin)
by the FDA, effective as of December 11, 2017.

The Employment Agreement provides that if there is a "separation form service" within the meaning of Section 409A of the U.S. Internal Revenue Code of
1986, as amended, as a result of (i) termination of the Executive's employment by us without "Cause" or (ii) the Executive resigns for "Good Reason," then
the  Executive  will  be  entitled  to  receive  severance  payments  in  the  amount  equal  to  at  least  eighteen  (18)  months  of  his  then  base  salary  paid  in  equal
installments  over  one  (1)  year,  and  conditional  upon  the  Executive  executing  a  full  and  general  Release  and  complying  with  certain  non-compete  and
confidentiality agreements. The Executive has no right to receive a cash bonus or any other form of remuneration.

The Executive shall not, for a period equal to one year following his termination of employment with us, directly or indirectly, compete with us in a business
in  the  development  and  commercialization  of  substantially  similar  endocrine  therapies  and  oncology  treatments;  solicit  any  of  our  clients  or  do  anything
whatsoever to induce or to lead any person to end, in whole or in part, its business relations with us; induce, attempt to induce or otherwise interfere in the
relations that we have with our distributors, suppliers, representatives, agents and other parties with whom we deal; or induce, attempt to induce or otherwise
solicit our

82

personnel to leave their employment with us or hire our personnel for any enterprise in which the Executive has an interest. The foregoing applies in those
geographic  areas  in  the  United  States,  Canada  and  Europe  in  which  the  same  or  substantially  similar  endocrine  therapies  and  oncology  treatment  are
developed and commercialized by us.

Pursuant to the Employment Agreement, the Executive is also entitled to receive certain payments in lieu of and not in addition to any severance payments
provided under the Employment Agreement (the "Change of Control Payments") in the event (i) a "Change of Control" occurs, and (ii) during the twelve-
month period following the Change of Control, either we terminate his employment without "Cause" or he terminates his employment for "Good Reason"
during  such  period.  The  Change  of  Control  Payment  will  equal  the  sum  of  the  following  amounts:  (i)  the  equivalent  of  eighteen  (18)  months  of  the
Executive’s then annual base salary, (ii) an amount equivalent to eighteen (18) months of the Executive’s annual bonus, if any, which he would have received
in the year immediately prior to the year the Change of Control occurred, and (iii) an amount equivalent to eighteen (18) months of the then monthly premium
to  provide  the  group  medical  benefits  to  the  any  earned  retention  bonus,  and  (iv)  an  amount  equivalent  to  eighteen  (18)  months  of  the  then  annual  cost
monthly  premium  to  provide  the  other  benefits  to  which  he  is  entitled,  or  our  cost  to  purchase  coverage  under  COBRA  for  such  benefits,  whichever  is
applicable.  group  medical  benefits  Executive,  his  spouse  and  dependents  determined  by  utilizing  the  applicable  COBRA  premium  rates  for  the  month  the
Executive’s employment terminates. The Change of Control Payment is subject to applicable statutory withholdings. Any outstanding stock options to acquire
our stock shall, in such circumstances, become fully exercisable, vested and non-forfeitable on the date the Executive’s employment terminates following a
Change of Contract during the term of the agreement. The payments are conditional on the Executive executing a full and general Release.

For the purposes of the Employment Agreement:

•

a "Change of Control" shall be deemed to have occurred in any of the following circumstances: (i) subject to certain exceptions, upon the acquisition by a
person (or one or more persons who are affiliates of one another or who are acting jointly or in concert) of a beneficial interest in our securities
representing in any circumstance 50% or more of the voting rights attaching to our then outstanding securities; (ii) upon a sale or other disposition of
all or substantially all of our assets; (iii) upon a plan of liquidation or dissolution of us; or (iv) if, for any reason, including our amalgamation, merger
or consolidation with or into another company, the individuals who, during the term of the change of control agreement, constituted the Board (and
any new directors whose appointment by the Board or whose nomination for election by our shareholders was approved by a vote of at least two-
thirds  of  the  directors  then  still  in  office  who  either  were  directors  during  the  term  of  the  change  of  control  agreement  or  whose  appointment  or
nomination for election was previously so approved) cease to constitute a majority of the members of the Board;

•

termination of employment for "Cause" includes (but is not limited to) (i) if the Executive commits any fraud, theft, embezzlement or other criminal act
of a similar nature, or (ii) if the Executive commits an act of serious misconduct or willful or gross negligence in the performance of his duties.

Termination  of  employment  by  the  Executive  for  "Good  Reason"  means  the  occurrence,  without  the  Executive’s  express  written  consent,  of  any  of  the
following acts: (i) a material reduction of the Executive’s base salary as in effect on the date of his Employment Agreement or as same may be increased from
time to time, and (ii) any material and sustained reduction in the Executive’s duties and responsibilities as Chief Executive Officer and the Board has been
provided with notice and fails to cure the situation within thirty (30) days following receipt of notice.

We entered into an Amended and Restated Consulting Agreement with Ms. Genevieve Lemaire effective as of February 18, 2016. The Company agreed to
pay the Consultant for her services performed under this Agreement at an hourly rate of CAN$170. At the conclusion of the Agreement, in December 2017,
the consultant was paid a bonus in the amount of CAN$20,000. There were no change of control provisions in or change of control benefits provided under
Ms. Lemaire’s Consulting Agreement. Ms. Lemaire continues to provide occasional services as agreed to and requested by the Company.

Exchange controls

Canada  has  no  system  of  exchange  controls.  There  are  no  exchange  restrictions  on  borrowing  from  foreign  countries  or  on  the  remittance  of  dividends,
interest, royalties and similar payments, management fees, loan repayments, settlement of trade debts or the repatriation of capital.

E.     Taxation

THE FOLLOWING SUMMARY IS OF A GENERAL NATURE ONLY AND IS NOT INTENDED TO BE, NOR SHOULD IT BE CONSTRUED TO BE,
LEGAL  OR  TAX  ADVICE  TO  ANY  PARTICULAR  HOLDER.  CONSEQUENTLY,  HOLDERS  ARE  URGED  TO  CONSULT  THEIR  OWN  TAX
ADVISORS FOR ADVICE AS TO THE TAX CONSEQUENCES OF AN INVESTMENT IN THE COMMON SHARES HAVING REGARD TO THEIR
PARTICULAR CIRCUMSTANCES.

Material Canadian Income Tax Considerations

The  following  summary  describes  the  principal  Canadian  federal  income  tax  considerations  applicable  to  a  holder  of  Common  Shares  and  who,  for  the
purposes of the Canadian federal Income Tax Act, R.S.C. 1985, as amended (the "Tax Act"), and at all relevant times, deals at arm's length with, and is not
affiliated  with,  the  Company  and  holds  their  Common  Shares  as  capital  property  (a  "holder").  Common  Shares  will  generally  be  considered  to  be  capital
property to a holder for purposes of the Tax Act unless either the holder holds such Common Shares in the course of carrying on a business of trading or
dealing in securities, or the holder has held or acquired such Common Shares in a transaction or transactions considered to be an adventure in the nature of
trade.

This summary is not applicable to a holder (i) that is a "financial institution", as defined in the Tax Act for purposes of the mark-to- market rules, (ii) that is a
"specified financial institution", as defined in the Tax Act, (iii) an interest in which would be a "tax shelter investment" as defined in the Tax Act, (iv) that has
made a functional currency reporting election for purposes of the Tax Act, (v) that has entered or will enter into a "derivative forward agreement", as defined
in the Tax Act, in respect of Common Shares, or (vi) that receives dividends on Common Shares under or as part of a dividend rental arrangement as defined
in the Tax Act. Such holders should consult their own tax advisors.

Additional considerations, not discussed herein, may be applicable to a holder that is a corporation resident in Canada, and is, or becomes, or does not deal at
arm's length for purposes of the Tax Act with a corporation resident in Canada that is or becomes, as part of a transaction or series of transactions or events
that  includes  the  acquisition  of  the  Common  Shares,  controlled  by  a  non-resident  corporation  for  the  purposes  of  the  "foreign  affiliate  dumping"  rules  in
section 212.3 of the Tax Act. Such holders should consult their tax advisors with respect to the consequences of acquiring Common Shares.

This  summary  is  based  upon  the  current  provisions  of  the  Tax  Act  and  the  regulations  promulgated  thereunder  (the  "Regulations")  and  the  Company's
understanding of the current published administrative policies and assessing practices of the Canada Revenue Agency ("CRA"). It also takes into account all
proposed amendments to the Tax Act and the Regulations publicly released by the Minister of Finance (Canada) prior to the date hereof ("Tax Proposals"),
and assumes that all such Tax Proposals will be enacted as currently proposed. No assurance can be given that the Tax Proposals will be enacted in the form
proposed or at all. This summary does not otherwise take into account or anticipate any changes in law or administrative or assessing practice or policy of the
CRA, whether by legislative, regulatory, judicial or administrative action or interpretation, nor does it address any provincial, local, territorial or foreign tax
considerations.

For  purposes  of  the  Tax  Act,  all  amounts,  including  dividends,  adjusted  cost  base  and  proceeds  of  disposition,  must  generally  be  determined  in  Canadian
dollars. Amounts denominated in a foreign currency must be converted to Canadian currency using exchange rates determined in accordance with the Tax
Act. The amount of any capital gain or any capital loss to a holder with respect to the Common Shares may be affected by fluctuations in Canadian dollar
exchange rates.

Holders Not Resident in Canada

The following discussion applies to a holder who, at all relevant times, for purposes of the Tax Act, is neither resident nor deemed to be resident in Canada
and does not, and is not deemed to, use or hold Common Shares in carrying on a business or part of a business in Canada (a "Non-Resident holder"). In
addition, this discussion does not apply to an insurer who carries or is deemed to carry on, an insurance business in Canada and elsewhere or to an "authorized
foreign bank" (as defined in the Tax Act).

Disposition of Common Shares

84

A  Non-Resident  holder  generally  will  not  be  subject  to  tax  under  the  Tax  Act  in  respect  of  any  capital  gain  realized  by  such  Non-  Resident  holder  on  a
disposition  or  deemed  disposition  of  Common  Shares  unless  such  shares  constitute  "taxable  Canadian  property"  (as  defined  in  the  Tax  Act)  of  the  Non-
Resident holder at the time of disposition and the gain is not exempt from tax pursuant to the terms of an applicable income tax treaty or convention. As long
as  the  Common  Shares  are  listed  on  a  designated  stock  exchange  (which  currently  includes  NASDAQ  and  the  TSX)  at  the  time  of  their  disposition,  the
Common  Shares  generally  will  not  constitute  taxable  Canadian  property  of  a  Non-Resident  holder,  unless  (a)  at  any  time  during  the  60-month  period
immediately preceding the disposition (i) one or any combination of (A) the Non-Resident holder, (B) persons with whom the Non-Resident holder did not
deal at arm's length, and (C) partnerships in which the Non-Resident holder or a person described in (B) holds a membership interest directly or indirectly
through one or more partnerships, owned 25% or more of the issued shares of any class or series of shares of the Company; and (ii) more than 50% of the fair
market value of the shares of the Company was derived directly or indirectly from one or any combination of real or immovable property situated in Canada,
"Canadian resource properties" (as defined in the Tax Act), "timber resource properties" (as defined in the Tax Act) or options in respect of, or interests in, or
for civil law rights in, any such property whether or not such property exists or (b) the Common Shares are otherwise deemed to be taxable Canadian property
to the Non-Resident holder.

A Non-Resident holder's capital gain (or capital loss) in respect of Common Shares that constitute or are deemed to constitute taxable Canadian property (and
are not "treaty-protected property" as defined in the Tax Act) will generally be computed in the manner described below under the heading "Holders Resident
in  Canada  -  Disposition  of  Common  Shares".  If  the  Common  Shares  were  to  cease  being  listed  on  NASDAQ,  the  TSX  or  another  "recognized  stock
exchange" (as defined in the Tax Act), a Non-Resident holder who disposes of Common Shares that are taxable Canadian property may be required to fulfill
the requirements of section 116 of the Tax Act, unless the Common Shares are "treaty-protected property" (as defined in the Tax Act) of the disposing Non-
Resident holder.

Non-Resident holders whose Common Shares are taxable Canadian property should consult their own tax advisors.

Taxation of Dividends on Common Shares

Dividends paid or credited or deemed to be paid or credited to a Non-Resident holder by the Company are subject to Canadian withholding tax at the rate of
25% unless reduced by the terms of an applicable tax treaty or convention. Under the Canada - United States Tax Convention (1980) (the "Convention") as
amended, the rate of withholding tax on dividends paid or credited to a Non-Resident holder who is the beneficial owner of the dividends, is resident in the
U.S. for purposes of the Convention and entitled to the benefits of the Convention (a "U.S. holder") is generally limited to 15% of the gross amount of the
dividend  (or  5%  in  the  case  of  a  U.S.  holder  that  is  a  company  beneficially  owning  at  least  10%  of  the  Company's  voting  shares).  Non-Resident  holders
should consult their own tax advisors.

Holders Resident in Canada

The following discussion applies to a holder of Common Shares who, at all relevant times, for purposes of the Tax Act, is or is deemed to be resident in
Canada  (a  "Canadian  holder").  Certain  Canadian  holders  whose  Common  Shares  might  not  otherwise  qualify  as  capital  property  may,  in  certain
circumstances, treat the Common Shares and every other "Canadian security" (as defined in the Tax Act) owned by the Canadian holder as capital property by
making an irrevocable election provided by subsection 39(4) of the Tax Act. Canadian holders should consult their own tax advisors for advice as to whether
an election under subsection 39(4) of the Tax Act is available and/or advisable in their particular circumstances.

Taxation of Dividends on Common Shares

Dividends received or deemed to have been received on the Common Shares will be included in a Canadian holder's income for purposes of the Tax Act.
Such dividends received or deemed to have been received by a Canadian holder that is an individual (other than certain trusts) will be subject to the gross-up
and dividend tax credit rules generally applicable under the Tax Act in respect of dividends received on shares of taxable Canadian corporations. Generally, a
dividend  will  be  eligible  for  the  enhanced  gross-up  and  dividend  tax  credit  if  the  Company  designates  the  dividend  as  an  "eligible  dividend"  (within  the
meaning of the Tax Act) in accordance with the provisions of the Tax Act. There may be limitations on the ability of the Company to designate dividends as
eligible dividends. A Canadian holder that is a corporation will be required to include such dividends in computing its income and will generally be entitled to
deduct the amount of such dividends in computing its taxable income. In certain circumstances, subsection 55(2) of the Tax Act may treat a taxable dividend
received by a Canadian holder that is a corporation as proceeds of disposition or a capital gain. A Canadian holder that is a "private corporation" or a "subject
corporation" (as such terms are defined in the Tax Act), may be liable under Part IV of the Tax Act to pay a refundable tax on dividends received or deemed
to have been received on the Common Shares to the extent such dividends are deductible in computing the holder's taxable income.

Disposition of Common Shares

85

A disposition, or a deemed disposition, of a Common Share by a Canadian holder will generally give rise to a capital gain (or a capital loss) equal to the
amount by which the proceeds of disposition of the share, net of any reasonable costs of disposition, exceed (or are less than) the adjusted cost base of the
share to the holder. Such capital gain (or capital loss) will be subject to the treatment described below under "Taxation of Capital Gains and Capital Losses".

Additional Refundable Tax

A Canadian holder that is a "Canadian-controlled private corporation" (as such term is defined in the Tax Act) may be liable to pay an additional refundable
tax on certain investment income including amounts in respect of "Taxable Capital Gains", as defined below.

Taxation of Capital Gains and Capital Losses

In general, one half of any capital gain (a "Taxable Capital Gain") realized by a Canadian holder in a taxation year will be included in the holder's income in
the year. Subject to and in accordance with the provisions of the Tax Act, one half of any capital loss (an "Allowable Capital Loss") realized by a Canadian
holder in a taxation year must be deducted from Taxable Capital Gains realized by the holder in the year and Allowable Capital Losses in excess of Taxable
Capital Gains may be carried back and deducted in any of the three preceding taxation years or carried forward and deducted in any subsequent taxation year
against net Taxable Capital Gains realized in such years. The amount of any capital loss realized by a Canadian holder that is a corporation on the disposition
or deemed disposition of a Common Share may be reduced by the amount of dividends received or deemed to have been received by it on such Common
Share (or on a share for which the Common Share has been substituted) to the extent and under the circumstances prescribed by the Tax Act. Similar rules
may apply where a corporation is a member of a partnership or a beneficiary of a trust that owns Common Shares, directly or indirectly, through a partnership
or a trust.

Alternative Minimum Tax

A Taxable Capital Gain realized and taxable dividends received or deemed to have been received by a Canadian holder who is an individual (including a trust,
other than certain specified trusts) may give rise to liability for alternative minimum tax.

Material U.S. Federal Income Tax Considerations

The following discussion is a summary of the material U.S. federal income tax consequences applicable to the ownership and disposition of Common Shares
by a U.S. Holder (as defined below), but does not purport to be a complete analysis of all potential U.S. federal income tax effects. This summary is based on
the Internal Revenue Code of 1986, as amended (the "Code"), U.S. Treasury regulations promulgated thereunder, IRS rulings and judicial decisions in effect
on the date hereof. All of these are subject to change, possibly with retroactive effect, or different interpretations. This summary does not discuss the potential
effects, whether adverse or beneficial, of any proposed legislation that, if enacted, could be applied on a retroactive basis. This summary is not binding on the
IRS, and the IRS is not precluded from taking a position that is different from, and contrary to, the positions taken in this summary.

This  summary  does  not  address  all  aspects  of  U.S.  federal  income  taxation  that  may  be  relevant  to  particular  U.S.  Holders  in  light  of  their  specific
circumstances (for example, U.S. Holders subject to the alternative minimum tax or the Medicare contribution tax on net investment income under the Code)
or to holders that may be subject to special rules under U.S. federal income tax law, including:

•

•

•

•

•

•

•

•

•

•

dealers in stocks, securities or currencies;

securities traders that use a mark-to-market accounting method;

banks and financial institutions;

insurance companies;

regulated investment companies;

real estate investment trusts;

tax-exempt organizations;

retirement plans, individual plans, individual retirement accounts and tax-deferred accounts;

partnerships or other pass-through entities for U.S. federal income tax purposes and their partners or members;

persons holding Common Shares as part of a hedging or conversion transaction straddle or other integrated or risk reduction transaction;

86

•

•

•

persons who or that are, or may become, subject to the expatriation provisions of the Code;

persons whose functional currency is not the U.S. dollar; and

direct, indirect or constructive owners of 10% or more of the total combined voting power of all classes of our voting stock or 10% or more of the
total value of shares of all classes of our stock.

This  summary  also  does  not  address  the  tax  consequences  of  holding,  exercising  or  disposing  of  warrants  in  the  Company.  If  the  Company  is  a  PFIC,  as
described  below,  U.S.  Holders  of  its  warrants  will  be  subject  to  adverse  tax  rules  and  will  not  be  able  to  make  the  mark-to-market  or  the  QEF  election
described  below  with  respect  to  such  warrants.  U.S.  Holders  of  warrants  should  consult  their  tax  advisors  with  regard  to  the  U.S.  federal  income  tax
consequences of holding, exercising or disposing of warrants in the Company, including in the situation in which the Company is classified as a PFIC.

This summary also does not discuss any aspect of state, local or foreign law, or estate or gift tax law as applicable to U.S. Holders. In addition, this discussion
is  limited  to  U.S.  Holders  holding  Common  Shares  as  capital  assets.  For  purposes  of  this  summary,  "U.S.  Holder"  means  a  beneficial  holder  of  Common
Shares who or that for U.S. federal income tax purposes is:

•

•

•

•

an individual citizen or resident of the United States;

a corporation or other entity classified as a corporation for U.S. federal income tax purposes created or organized in or under the laws of the United
States, any state thereof or the District of Columbia;

an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

a trust, if (a) a court within the United States is able to exercise primary supervision over the administration of such trust and one or more "U.S.
persons" (within the meaning of the Code) have the authority to control all substantial decisions of the trust, or (b) a valid election is in effect to be
treated as a U.S. person for U.S. federal income tax purposes.

If a partnership or other entity or arrangement classified as a partnership for U.S. federal income tax purposes holds Common Shares, the U.S. federal income
tax  treatment  of  a  partner  generally  will  depend  on  the  status  of  the  partner  and  the  activities  of  the  partnership.  This  summary  does  not  address  the  tax
consequences to any such partner. Such a partner should consult its own tax advisor as to the tax consequences of the partnership owning and disposing of
Common Shares.

U.S.  HOLDERS  SHOULD  CONSULT  THEIR  OWN  TAX  ADVISORS  WITH  REGARD  TO  THE  APPLICATION  OF  THE  TAX  CONSEQUENCES
DESCRIBED BELOW TO THEIR PARTICULAR SITUATIONS AS WELL AS THE APPLICATION OF ANY STATE, LOCAL, FOREIGN OR OTHER
TAX LAWS, INCLUDING GIFT AND ESTATE TAX LAWS.

Tax Consequences if we are a Passive Foreign Investment Company ("PFIC")

A foreign corporation will be classified as a PFIC for any taxable year in which, after taking into account the income and assets of the corporation and certain
subsidiaries pursuant to applicable "look-through rules", either (i) at least 75% of its gross income is "passive income" or (ii) at least 50% of the average
quarterly value of its assets is attributable to assets which produce passive income or are held for the production of passive income. Passive income generally
includes dividends, interest, rents and royalties (other than certain rents and royalties derived in the active conduct of a trade or business), annuities and gains
from assets that produce passive income. If a non-U.S. corporation owns at least 25% by value of the stock of another corporation, the non-U.S. corporation is
treated for purposes of the PFIC tests as owning its proportionate share of the assets of the other corporation and as receiving directly its proportionate share
of the other corporation's income.

The Company believes it was a PFIC for the 2015 taxable year but not for the 2016 and 2017 taxable years. However, the fair market value of the Company's
assets may be determined in large part by the market price of the Common Shares, which is likely to fluctuate, and the composition of the Company's income
and assets will be affected by how, and how quickly, the Company spends any cash that is raised in any financing transaction. Thus, no assurance can be
provided that the Company will not be classified as a PFIC for 2018 or any future taxable year. U.S. Holders should consult their tax advisors regarding the
Company's PFIC status.

If  the  Company  is  classified  as  a  PFIC  for  any  taxable  year  during  which  a  U.S.  Holder  owns  Common  Shares,  the  U.S.  Holder,  absent  certain  elections
(including the mark-to-market and QEF elections described below), will generally be subject to adverse rules (regardless of whether the Company continues
to be classified as a PFIC) with respect to (i) any "excess distributions" (generally, any distributions received by the U.S. Holder on the Common Shares in a
taxable year that are greater than 125% of the average annual distributions received by the U.S. Holder in the three preceding taxable years or, if shorter, the

87

U.S. Holder's holding period for the Common Shares) and (ii) any gain realized on the sale or other disposition of the Common Shares.

Under these adverse rules (a) the excess distribution or gain will be allocated ratably over the U.S. Holder's holding period, (b) the amount allocated to the
current taxable year and any taxable year prior to the first taxable year in which the Company is classified as a PFIC will be taxed as ordinary income, and (c)
the amount allocated to each of the other taxable years during which the Company was classified as a PFIC will be subject to tax at the highest rate of tax in
effect for the applicable category of taxpayer for that year and an interest charge will be imposed with respect to the resulting tax attributable to each such
other taxable year. A U.S. Holder that is not a corporation will be required to treat any such interest paid as "personal interest", which is not deductible.

U.S. Holders can avoid the adverse rules described above in part by making a mark-to-market election with respect to the Common Shares, provided that the
Common Shares are "marketable". The Common Shares will be marketable if they are "regularly traded" on a "qualified exchange" or other market within the
meaning  of  applicable  U.S.  Treasury  regulations.  For  this  purpose,  the  Common  Shares  generally  will  be  considered  to  be  regularly  traded  during  any
calendar year during which they are traded, other than in de minimis quantities, on at least 15 days during each calendar quarter. The Common Shares are
currently listed on NASDAQ, which constitutes a qualified exchange; however, there can be no assurance that the Common Shares will be treated as regularly
traded for purposes of the mark-to-market election on a qualified exchange. If the Common Shares were not regularly traded on NASDAQ or were delisted
from NASDAQ and were not traded on another qualified exchange for the requisite time period described above, the mark-to-market election would not be
available.

A U.S. Holder that makes a mark-to-market election must include in gross income, as ordinary income, for each taxable year an amount equal to the excess, if
any, of the fair market value of the U.S. Holder's Common Shares at the close of the taxable year over the U.S. Holder's adjusted tax basis in the Common
Shares.  An  electing  U.S.  Holder  may  also  claim  an  ordinary  loss  deduction  for  the  excess,  if  any,  of  the  U.S.  Holder's  adjusted  tax  basis  in  the  Common
Shares over the fair market value of the Common Shares at the close of the taxable year, but this deduction is allowable only to the extent of any net mark-to-
market gains previously included in income. A U.S. Holder that makes a mark-to-market election generally will adjust such U.S. Holder's tax basis in the
Common Shares to reflect the amount included in gross income or allowed as a deduction because of such mark-to-market election. Gains from an actual sale
or other disposition of the Common Shares will be treated as ordinary income, and any losses incurred on a sale or other disposition of the Common Shares
will be treated as ordinary losses to the extent of any net mark-to-market gains previously included in income.

If the Company is classified as a PFIC for any taxable year in which a U.S. Holder owns Common Shares but before a mark-to-market election is made, the
adverse PFIC rules described above will apply to any mark-to-market gain recognized in the year the election is made. Otherwise, a mark-to-market election
will be effective for the taxable year for which the election is made and all subsequent taxable years. The election cannot be revoked without the consent of
the IRS unless the Common Shares cease to be marketable, in which case the election is automatically terminated.

If the Company is classified as a PFIC, a U.S. Holder of Common Shares will generally be treated as owning stock owned by the Company in any direct or
indirect subsidiaries that are also PFICs and will be subject to similar adverse rules with respect to distributions to the Company by, and dispositions by the
Company of, the stock of such subsidiaries. A mark-to-market election is not permitted for the shares of any subsidiary of the Company that is also classified
as a PFIC. U.S. Holders should consult their tax advisors regarding the availability of, and procedure for making, a mark-to-market election.

In some cases, a shareholder of a PFIC can avoid the interest charge and the other adverse PFIC consequences described above by making a QEF election to
be taxed currently on its share of the PFIC's undistributed income. We will endeavor to satisfy the record keeping requirements that apply to a QEF and to
supply requesting U.S. Holders with the information that such U.S. Holders are required to report under the QEF rules. However, there can be no assurance
that the Company will satisfy the record keeping requirements or provide the information required to be reported by U.S. Holders.

A U.S. Holder that makes a timely and effective QEF election for the first tax year in which its holding period of its Common Shares begins generally will not
be subject to the adverse PFIC consequences described above with respect to its Common Shares. Rather, a U.S. Holder that makes a timely and effective
QEF election will be subject to U.S. federal income tax on such U.S. Holder's pro rata share of (a) the Company's net capital gain, which will be taxed as
long-term capital gain to such U.S. Holder, and (b) the Company's ordinary earnings, which will be taxed as ordinary income to such U.S. Holder, in each
case regardless of which such amounts are actually distributed to the U.S. Holder by the Company. Generally, "net capital gain" is the excess of (a) net long-
term capital gain over (b) net short-term capital loss, and "ordinary earnings" are the excess of (a) "earnings and profits" over (b) net capital gain.

88

A U.S. Holder that makes a timely and effective QEF election with respect to the Company generally (a) may receive a tax-free distribution from us to the
extent that such distribution represents "earnings and profits" that were previously included in income by the U.S. Holder because of such QEF election and
(b) will adjust such U.S. Holder's tax basis in the Common Shares to reflect the amount included in income or allowed as a tax-free distribution because of
such QEF election. In addition, a U.S. Holder that makes a QEF election generally will recognize capital gain or loss on the sale or other taxable disposition
of Common Shares.

The QEF election is made on a shareholder-by-shareholder basis. Once made, a QEF election will apply to the tax year for which the QEF election is made
and to all subsequent tax years, unless the QEF election is invalidated or terminated or the IRS consents to revocation of the QEF election. In addition, if a
U.S. Holder makes a QEF election, the QEF election will remain in effect (although it will not be applicable) during those tax years in which the Company is
not a PFIC.

If the Company is classified as a PFIC and then ceases to be so classified, a U.S. Holder may make an election (a "deemed sale election") to be treated for
U.S. federal income tax purposes as having sold such U.S. Holder's Common Shares on the last day of the taxable year of the Company during which it was a
PFIC. A U.S. Holder that made a deemed sale election would then cease to be treated as owning stock in a PFIC by reason of ownership of Common Shares
in the Company. However, gain recognized as a result of making the deemed sale election would be subject to the adverse rules described above and loss
would not be recognized.

If the Company is a PFIC in any year with respect to a U.S. Holder, the U.S. Holder will be required to file an annual information return on IRS Form 8621
regarding distributions received on Common Shares and any gain realized on the disposition of Common Shares.

In addition, if the Company is a PFIC, U.S. Holders will generally be required to file an annual information return with the IRS (also on IRS Form 8621,
which PFIC shareholders are required to file with their U.S. federal income tax or information returns) relating to their ownership of Common Shares.

U.S. Holders should consult their tax advisors regarding the potential application of the PFIC regime and any reporting obligations to which they may be
subject under that regime.

Dividends

Subject to the PFIC rules discussed above, any distributions paid by the Company out of current or accumulated earnings and profits (as determined for U.S.
federal  income  tax  purposes),  before  reduction  for  any  Canadian  withholding  tax  paid  with  respect  thereto,  will  generally  be  taxable  to  a  U.S.  Holder  as
foreign source dividend income, and will not be eligible for the dividends received deduction generally allowed to corporations. Distributions in excess of
current  and  accumulated  earnings  and  profits  will  be  treated  as  a  non-taxable  return  of  capital  to  the  extent  of  the  U.S.  Holder's  adjusted  tax  basis  in  the
Common Shares and thereafter as capital gain. The Company does not, however, intend to calculate its earnings and profits under U.S. federal income tax
principles. Therefore, U.S. Holders should expect that any distribution from the Company generally will be treated for U.S. federal income tax purposes as a
dividend. U.S. Holders should consult their own tax advisors with respect to the appropriate U.S. federal income tax treatment of any distribution received
from the Company.

Dividends paid to non-corporate U.S. Holders by the Company in a taxable year in which it is treated as a PFIC, or in the immediately following taxable year,
will not be eligible for the special reduced rates normally applicable to long-term capital gains. In all other taxable years, dividends paid by the Company
should be taxable to a non-corporate U.S. Holder at the special reduced rates normally applicable to long-term capital gains, provided that certain conditions
are satisfied. (including a minimum holding period requirement). The Company believes it was not a PFIC for the 2017 taxable year. However, no assurance
can be provided that the Company will not be classified as a PFIC for 2018 and, therefore, no assurance can be provided that a U.S. Holder will be able to
claim a reduced rate for dividends paid in 2018 or 2019 (if any). See "Passive Foreign Investment Company Considerations" above.

Under current law, payments of dividends by the Company to non-Canadian investors are generally subject to a 25% Canadian withholding tax. The rate of
withholding tax applicable to U.S. Holders that are eligible for benefits under the Canada-United States Tax Convention (the "Convention") is reduced to a
maximum of 15%. This reduced rate of withholding will not apply if the dividends received by a U.S. Holder are effectively connected with a permanent
establishment of the U.S. Holder in Canada. For U.S. federal income tax purposes, U.S. Holders will be treated as having received the amount of Canadian
taxes withheld by the Company, and as then having paid over the withheld taxes to the Canadian taxing authorities. As a result of this rule, the amount of
dividend income included in gross income for U.S. federal income tax purposes by a U.S. Holder with respect to a payment of dividends may be greater than
the amount of cash actually received (or receivable) by the U.S. Holder from the Company with respect to the payment.

89

Subject  to  certain  limitations,  a  U.S.  Holder  will  generally  be  entitled,  at  the  election  of  the  U.S.  Holder,  to  a  credit  against  its  U.S.  federal  income  tax
liability, or a deduction in computing its U.S. federal taxable income, for Canadian income taxes withheld by the Company. This election is made on a year-
by-year basis and applies to all foreign taxes paid (whether directly or through withholding) by a U.S. Holder during a year. For purposes of the foreign tax
credit limitation, dividends paid by the Company generally will constitute foreign source income in the "passive category income" basket. The foreign tax
credit  rules  are  complex  and  U.S.  Holders  should  consult  their  tax  advisors  concerning  the  availability  of  the  foreign  tax  credit  in  their  particular
circumstances.

Dividends paid in Canadian dollars will be included in the gross income of a U.S. Holder in a U.S. dollar amount calculated by reference to the exchange rate
in effect on the date the U.S. Holder (actually or constructively) receives the dividend, regardless of whether such Canadian dollars are actually converted into
U.S. dollars at that time. If the Canadian dollars received are not converted into U.S. dollars on the date of receipt, a U.S. Holder will have a tax basis in the
Canadian dollars equal to their U.S. dollar value on the date of receipt. Gain or loss, if any, realized on a sale or other disposition of the Canadian dollars will
generally be U.S. source ordinary income or loss to a U.S. Holder.

The Company generally does not pay any dividends and does not anticipate paying any dividends in the foreseeable future.

Sale, Exchange or Other Taxable Disposition of Common Shares

Subject to the PFIC rules discussed above, upon a sale, exchange or other taxable disposition of Common Shares, a U.S. Holder generally will recognize
capital gain or loss for U.S. federal income tax purposes equal to the difference, if any, between the amount realized on the sale, exchange or other taxable
disposition and the U.S. Holder's adjusted tax basis in the Common Shares.

This capital gain or loss will be long-term capital gain or loss if the U.S. Holder's holding period in the Common Shares exceeds one year. The deductibility
of capital losses is subject to limitations. Any gain or loss will generally be U.S. source for U.S. foreign tax credit purposes.

Information Reporting and Backup Withholding

Payments made within the U.S., or by a U.S. payor or U.S. middleman, of dividends on, and proceeds arising from sales or other dispositions of Common
Shares, generally will be reported to the IRS and to the U.S. Holder as required under applicable regulations. Backup withholding tax may apply to these
payments if the U.S. Holder fails to timely provide in the appropriate manner an accurate taxpayer identification number or otherwise fails to comply with, or
establish  an  exemption  from,  such  backup  withholding  tax  requirements.  Certain  U.S.  Holders  are  not  subject  to  the  information  reporting  or  backup
withholding tax requirements described herein. U.S. Holders should consult their tax advisors as to their qualification for exemption from backup withholding
tax and the procedure for establishing an exemption.

Backup withholding tax is not an additional tax. U.S. Holders generally will be allowed a refund or credit against their U.S. federal income tax liability for
amounts withheld, provided the required information is timely furnished to the IRS.

Subject to certain exceptions and future guidance, U.S. tax legislation generally requires a U.S. Holder that is a specified individual or a domestic entity, to
report annually to the IRS on IRS Form 8938 such U.S. Holder's interests in stock or securities issued by a non-U.S. person (such as the Company). U.S.
Holders should consult their tax advisors regarding the information reporting obligations that may arise from their acquisition, ownership or disposition of
Common Shares.

Item 11.

Quantitative and Qualitative Disclosures About Market Risk

Fair value

The Company classifies its financial instruments in the following categories: "Financial assets at fair value through profit or loss ("FVTPL")"; "Loans and
receivables"; "Financial liabilities at FVTPL"; and "Other financial liabilities".

•

•

•

The Company's loans and receivables are comprised of cash and cash equivalents, trade and other receivables and restricted cash equivalents.

Financial liabilities at FVTPL are currently comprised of the Company's warrant liability.

Other financial liabilities include payables, accrued liabilities, and provision for restructuring costs.

The carrying values of all of the aforementioned financial instruments, excluding warrant liability which is stated at fair value, approximate their fair values
due to their short-term maturity or to the prevailing interest rates of these instruments, which are comparable to those of the market.

Financial risk factors

The following provides disclosures relating to the nature and extent of the Company's exposure to risks arising from financial instruments, including credit
risk, liquidity risk and market risk (share price risk) and how the Company manages those risks.

(a) Credit risk

Credit risk is the risk of an unexpected loss if a customer or counterparty to a financial instrument fails to meet its contractual obligations. The Company
regularly monitors credit risk exposure and takes steps to mitigate the likelihood of this exposure resulting in losses. The Company's exposure to credit risk
currently  relates  to  the  loans  and  receivables  in  the  table  above.  The  Company  holds  its  available  cash  in  amounts  that  are  readily  convertible  to  known
amounts  of  cash  and  deposits  its  cash  balances  with  financial  institutions  that  have  an  investment  grade  rating  of  at  least  "P-2"  or  the  equivalent.  This
information is supplied by independent rating agencies where available and, if not available, the Company uses publicly available financial information to
ensure that it invests its cash in creditworthy and reputable financial institutions.

As at December 31, 2017 trade accounts receivable for an amount of approximately $20,000 were with three counterparties, and no trade accounts receivable
were past due and none were impaired.

Generally, the Company does not require collateral or other security from customers for trade accounts receivable; however, credit is extended following an
evaluation of creditworthiness. In addition, the Company performs ongoing credit reviews of all of its customers and establishes an allowance for doubtful
accounts when accounts are determined to be uncollectible.

The maximum exposure to credit risk approximates the amount recognized in the Company's consolidated statement of financial position.

91

(b) Liquidity risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they become due. As indicated in note 21 - Capital disclosures,
the  Company  manages  this  risk  through  the  management  of  its  capital  structure.  It  also  manages  liquidity  risk  by  continuously  monitoring  actual  and
projected  cash  flows.  The  Board  of  Directors  reviews  and  approves  the  Company's  operating  and  capital  budgets,  as  well  as  any  material  transactions
occurring outside of the ordinary course of business. The Company has adopted an investment policy in respect of the safety and preservation of its capital to
ensure the Company's liquidity needs are met. The instruments are selected with regard to the expected timing of expenditures and prevailing interest rates.

On December 20, 2017, the FDA granted marketing approval for Macrilen™ (macimorelin) to be used in the diagnosis of patients with AGHD. On January
16, 2018, the Company, through AEZS Germany entered into the Strongbridge License Agreement. The Strongbridge License Agreement will contribute to
fulfilling the Company's future obligations (see note 26 - Subsequent events).

(c) Market risk

Share price risk

The change in fair value of the Company's warrant liability, which is measured at FVTPL, results from the periodic "mark-to-market" revaluation, via the
application  of  option  pricing  models,  of  currently  outstanding  share  purchase  warrants.  These  valuation  models  are  impacted,  among  other  inputs,  by  the
market price of the Company's common shares. As a result, the change in fair value of the warrant liability, which is reported in the consolidated statements of
comprehensive loss, has been and may continue in future periods to be materially affected most notably by changes in the Company's common share closing
price, which on the NASDAQ ranged from $0.84 to $3.65 during the year ended December 31, 2017.

If variations in the market price of our common shares of -30% and +30% were to occur, the impact on the Company's net loss related to the warrant liability
held at December 31, 2017 would be as follows:

currency transaction and translation gains and losses.

Controls and Procedures

Under  the  supervision  and  with  the  participation  of  our  management,  including  the  Chief  Executive  Officer  and  the  Chief  Financial  Officer,  we  have
evaluated the effectiveness of our disclosure controls and procedures as at December 31, 2017. Based on that evaluation, the Chief Executive Officer and
Chief Financial Officer have concluded that these disclosure controls and procedures were effective as at December 31, 2017.

Management's Annual Report on Internal Control over Financial Reporting

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting.  Our  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 IFRS as issued by the IASB.

Our internal control over financial reporting includes those policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of the assets of Aeterna Zentaris; (ii) provide reasonable assurance that transactions are recorded
as necessary to permit preparation of financial statements in accordance with IFRS, and that receipts and expenditures of the Company are being made only in
accordance  with  authorizations  of  Company  management;  and  (iii)  provide  reasonable  assurance  regarding  prevention  or  timely  detection  of  unauthorized
acquisition, use or disposition of Company 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.

Management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the criteria established in Internal Control
– Integrated Framework: 2013 issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management
has concluded that our internal control over financial reporting was effective as at December 31, 2017.

93

Changes in Internal Controls over Financial Reporting

There were no changes in our internal control over financial reporting during the year ended December 31, 2017 that materially affected, or are reasonably
likely to materially affect, our internal control over financial reporting.

The  design  of  any  system  of  controls  and  procedures  is  based  in  part  upon  certain  assumptions  about  the  likelihood  of  certain  events.  There  can  be  no
assurance that any design will succeed in achieving its stated goals under all potential future conditions, including conditions that are remote.

In  accordance  with  Securities  and  Exchange  Commission’s  rules  regarding  non-accelerated  filers,  this  Annual  Report  on  Form  20-F  does  not  include  an
attestation report of the Company's independent registered public accounting firm regarding the Company's internal control over financial reporting.

Item 16A. Audit Committee Financial Expert

Our Board has determined that we have at least one audit committee financial expert (as defined in paragraph (b) of Item 16A to Form 20-F). The name of the
audit committee financial expert is Mr. Gérard Limoges, FCPA, FCA, the Audit Committee's Chairman. In accordance with Item 16A, paragraph (d) of Form
20-F, the designation of Mr. Limoges as our audit committee financial expert does not: (i) make Mr. Limoges an "expert" for any purpose, including without
limitation for purposes of Section 11 of the Securities Act of 1933, as amended, as a result of this designation; (ii) impose any duties, obligations or liability
on Mr. Limoges that are greater than those imposed on him as a member of the Audit Committee and the Board in the absence of such designation; or (iii)
affect the duties, obligations or liability of any other member of the Audit Committee or the Board. The other members of the Audit Committee are Messrs.
Michael Cardiff and Juergen Ernst, each of whom, along with Mr. Limoges, is independent, as that term is defined in the NASDAQ listing standards. For a
description of their respective education and experience, please refer to "Item 6. – Directors, Senior Management and Employees".

Item 16B. Code of Ethics

On December 16, 2017, the Board adopted a "Code of Conduct and Business Ethics", which replaced the then existing Code of Ethical Conduct as of January
1, 2018. The Code of Conduct and Business Ethics expanded on the previous Code of Ethical Conduct to provide additional details of expected conduct of all
employees  and  directors  of  the  Company,  including  specific  obligations  the  Company  and  its  employees  has  as  a  member  of  the  healthcare  industry.  We
selected an independent third party supplier to provide a confidential and anonymous communication channel for reporting concerns about possible violations
to  our  Code  of  Ethical  Conduct  as  well  as  financial  and/or  accounting  irregularities  or  fraud.  A  copy  of  the  Code  of  Ethical  Conduct,  as  amended,  is
incorporated by reference as Exhibit 11.1 to this Annual Report on Form 20-F and is also available on our Web site at www.aezsinc.com under the Investors -
Corporate Governance tab. The Code of Ethical Conduct is a "code of ethics" as defined in paragraph (b) of Item 16B to Form 20- F. The Code of Ethical
Conduct applies to all of our employees, directors and officers, including our principal executive officer, principal financial officer, and principal accounting
officer  or  controller,  or  persons  performing  similar  functions,  and  includes  specific  provisions  dealing  with  integrity  in  accounting  matters,  conflicts  of
interest and compliance with applicable laws and regulations. On December 4, 2014, our Board of Directors adopted a "Code of Business Conduct and Ethics
for  Members  of  the  Board  of  Directors",  which  is  incorporated  by  reference  as  Exhibit  11.2  to  this  Annual  Report  on  Form  20-F.  We  will  provide  these
documents without charge to any person or company upon request to our Corporate Secretary, at our head office at 315 Sigma Drive, Summerville, South
Carolina 29486.

Item 16C. Principal Accountant Fees and Services

(All amounts are in U.S. dollars)

(a)

Audit Fees

During the  financial  years  ended  December  31,  2017  and  2016,  the  Company's  principal  accountant,  PricewaterhouseCoopers  LLP,  billed  $506,309  and
$363,962, respectively, for the audit of the Company's annual consolidated financial statements and for services rendered in connection with statutory and
regulatory filings.

94

(b)

Audit-related Fees

During  the  financial  years  ended  December  31,  2017  and  2016,  the  Company's  principal  accountant,  PricewaterhouseCoopers  LLP,  billed  $113,430  and
$164,477, respectively, for audit or attest services not required by statute or regulation, for accounting consultations on proposed transactions, for the review
of prospectuses and prospectus supplements, including the delivery of customary consent and comfort letters in connection therewith.

(c)

Tax Fees

During  the  financial  years  ended  December  31,  2017  and  2016,  the  Company's  principal  accountants,  PricewaterhouseCoopers  LLP  billed  $5,426  and

(d)

All Other Fees

During the financial years ended December 31, 2017 and 2016, the Company's principal accountant, PricewaterhouseCoopers LLP, did not bill us for services
not included in audit fees, audit-related fees and tax fees.

(e)

Audit Committee Pre-Approval Policies and Procedures

Under applicable Canadian securities regulations, we are required to disclose whether our Audit Committee has adopted specific policies and procedures for
the engagement of non-audit services and to prepare a summary of these policies and procedures. The Audit Committee Charter (incorporated by reference as
Exhibit 11.3 to this Annual Report on Form 20-F) provides that it is such committee's responsibility to approve all audit engagement fees and terms as well as
reviewing policies for the provision of non-audit services by the external auditors and, when required, the framework for pre-approval of such services. The
Audit  Committee  delegates  to  its  Chairman  the  pre-approval  of  such  non-audit  fees.  The  pre-approval  by  the  Chairman  is  then  presented  to  the  Audit
Committee at its first scheduled meeting following such pre-approval.

For each of the years ended December 31, 2017 and 2016, there were no non-audit services provided by our external auditor that required the approval from
the Audit Committee pursuant to the "de minimis exception" to the pre-approval requirement for non-audit services.

(f)

Work performed by Full-time, Permanent Employees of Principal Accountant

During  the  financial  year  ended  December  31,  2017,  no  person  other  than  the  full-time,  permanent  employees  of  our  principal  accountant,
PricewaterhouseCoopers LLP, performed more than 50% of the audit work on our financial statements.

Item 16D. Exemptions from the Listing Standards for Audit Committees

None.

Item 16E.

Purchases of Equity Securities by the Issuer and Affiliated Purchasers

None.

Item 16F. Change in Registrant's Certifying Accountant

None.

Item 16G. Corporate Governance

We  are  generally  in  compliance  with  the  corporate  governance  requirements  of  NASDAQ  except  as  described  below.  We  are  not  in  compliance  with  the
NASDAQ requirement that a quorum for a meeting of the holders of our Common Shares be no less than 33 1/3% of such outstanding shares. Our bylaws
provide  that  a  quorum  for  purposes  of  any  meeting  of  our  shareholders  consists  of  at  least  10%  of  the  outstanding  voting  shares.  We  benefit  from  an
exemption from NASDAQ from this quorum requirement because the quorum provided for in our bylaws complies with the requirements of the CBCA, our
governing corporate statute, and with the rules of TSX, the home country exchange on which our voting shares are traded. In accordance with applicable
current

95

NASDAQ  requirements,  we  have  in  the  past,  and  upon  request,  provided  to  NASDAQ  letters  from  outside  counsel  certifying  that  these  practices  are  not
prohibited by our home country law.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of

Aeterna Zentaris Inc.

Opinion on the Financial Statements

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Aeterna  Zentaris  Inc.  and  its  subsidiaries  as  of  December  31,  2017  and  December  31,
2016, and the related consolidated statements of changes in shareholder’s (deficiency) equity, comprehensive loss and cash flow for each of the three years in
the  period  ended  December  31,  2017,  including  the  related  notes  (collectively  referred  to  as  the  "consolidated  financial  statements").  In  our  opinion,  the
consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and December 31,
2016, and their financial performance and their cash flows for each of the three years in the period ended December 31, 2017 in conformity with International
Financial Reporting Standards as issued by the International Accounting Standards Board.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s
consolidated  financial  statements  based  on  our  audits.  We  are  a  public  accounting  firm  registered  with  the  Public  Company  Accounting  Oversight  Board
(United  States)  ("PCAOB")  and  are  required  to  be  independent  with  respect  to  the  Company  in  accordance  with  the  U.S.  federal  securities  laws  and  the
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error
or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits
we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of
the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud,
and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures
in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as
well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

novel pharmaceutical therapies. On December 20, 2017, the FDA granted marketing approval for Macrilen™ (macimorelin) to be used in the diagnosis
of  patients  with  AGHD.  On  January  16,  2018,  the  Company  through  AEZS  Germany  entered  into  a  license  and  assignment  agreement  with
Strongbridge  Ireland  Limited  ("Strongbridge")  to  carry  out  development,  manufacturing,  registration  and  commercialization  of  Macrilen™
(macimorelin) in the United States and Canada (the "Strongbridge License Agreement").

Reporting entity

The accompanying consolidated financial statements include the accounts of Aeterna Zentaris Inc., an entity incorporated under the Canada Business
Corporations Act, and its wholly-owned subsidiaries (collectively referred to as the "Group"). Aeterna Zentaris Inc. is the ultimate parent company of
the Group.

The  Company  currently  has  three  wholly-owned  direct  and  indirect  subsidiaries,  Aeterna  Zentaris  GmbH  ("AEZS  Germany"),  based  in  Frankfurt,
Germany,  Zentaris  IVF  GmbH,  a  wholly-owned  subsidiary  of  AEZS  Germany,  based  in  Frankfurt,  Germany,  and  Aeterna  Zentaris,  Inc.,  an  entity

(tabular amounts in thousands of US dollars, except share/option/warrant and per share/option/warrant data and as otherwise noted)

Basis of presentation

(a) Statement of compliance

These consolidated financial statements as at December 31, 2017 and December 31, 2016 and for the years ended December 31, 2017, 2016 and 2015
have  been  prepared  in  accordance  with  International  Financial  Reporting  Standards  ("IFRS")  as  issued  by  the  International  Accounting  Standards
Board ("IASB").

The accounting policies in these consolidated financial statements are consistent with those of the previous financial year and previous quarter.

These consolidated financial statements were approved by the Company's Board of Directors on March 27, 2018.

The  preparation  of  financial  statements  in  accordance  with  IFRS  requires  the  use  of  certain  critical  accounting  estimates  and  the  exercise  of
management's judgment in applying the Company's accounting policies. Areas involving a high degree of judgment or complexity and areas where
assumptions and estimates are significant to the Company's consolidated financial statements are discussed in note 3 - Critical accounting estimates
and judgments.

(b) Principles of consolidation

These consolidated financial statements include any entity in which the Company directly or indirectly holds more than 50% of the voting rights or
over which the Company exercises control. The Company controls an entity when the Company is exposed to, or has rights to, variable returns from its
involvement with the entity and has the ability to affect those returns through its power over the entity. An entity is included in the consolidation from
the  date  that  control  is  transferred  to  the  Company,  while  any  entities  that  are  sold  are  excluded  from  the  consolidation  from  the  date  that  control
ceases. All inter-company balances and transactions are eliminated on consolidation.

(c) Foreign currency

Items included in the financial statements of the Group's entities are measured using the currency of the primary economic environment in which the
entities operate (the "functional currency"). On January 1, 2015, the Company and its U.S. subsidiary, Aeterna Zentaris, Inc., changed their functional
currency from the Euro ("EUR") to the U.S. dollar, given that changes to underlying transactions, events and conditions indicated that the U.S. dollar
more appropriately reflects the primary economic environment in which these entities operate. This change in functional currency was accounted for
prospectively. The functional currency of the German subsidiaries remains the EUR.

Assets and liabilities of the German subsidiaries are translated from EUR balances at the period-end exchange rates, and the results of operations are
translated  from  EUR  amounts  at  average  rates  of  exchange  for  the  period.  The  resulting  translation  adjustments  are  included  in  accumulated  other
comprehensive income within shareholders' (deficiency) equity.

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the underlying transaction.
Foreign  exchange  gains  and  losses  resulting  from  the  settlement  of  such  transactions  and  from  the  translation  of  monetary  assets  and  liabilities  not
denominated in the functional currency are recognized in the consolidated statement of comprehensive loss.

Foreign exchange gains and losses that relate to cash and cash equivalents are presented within finance income or finance costs in the consolidated
statement of comprehensive loss. All other foreign exchange gains and losses are presented in the consolidated statement of comprehensive loss within
operating expenses.

(d) Share consolidation (reverse stock split)

On  November  17,  2015,  the  Company  effected  a  consolidation  of  its  issued  and  outstanding  common  shares  on  a  100  to  1  basis  (the  "Share
Consolidation"). The Share Consolidation affected all shareholders, option holders and warrant holders uniformly and thus did not materially affect any
security  holder's  percentage  of  ownership  interest.  All  references  in  these  consolidated  financial  statements  to  common  shares,  options  and  share
purchase warrants have been retroactively adjusted to reflect the Share Consolidation.

2 Summary of significant accounting policies

The accounting policies set out below have been applied consistently to all years presented in these consolidated financial statements and have been
applied consistently by all Group entities.

Cash and cash equivalents

Cash and cash equivalents consist of unrestricted cash on hand and balances with banks, as well as short-term interest-bearing deposits, such as money
market accounts, that are readily convertible to known amounts of cash and are subject to an insignificant risk of changes in value, with a maturity of
three months or less from the date of acquisition.

Inventories

Inventories  are  valued  at  the  lower  of  cost  or  net  realizable  value.  Cost  is  determined  using  the  first-in,  first-out  method  for  all  inventories.  The
Company's policy is to write down inventory that has become obsolete and inventory that has a cost basis in excess of its expected net realizable value.
Increases in the reserve are recorded as charges in cost of product sales. For product candidates that have not been approved by the FDA, inventory
used in clinical trials is wrote down at the time of production and recorded as research and development ("R&D") costs. For products that have been
approved by the FDA, inventory used in clinical trials is expensed at the time the inventory is packaged for the clinical trial. All direct manufacturing
costs incurred after approval are capitalized into inventory.

Restricted cash equivalents

Restricted cash equivalents are comprised of bank deposits, related to a guarantee for a long-term operating lease obligation and for a corporate credit
card program that cannot be used for current purposes.

Property, plant and equipment and depreciation

Items of property, plant and equipment are recorded at cost, net of related government grants and accumulated depreciation and impairment charges.
Depreciation is calculated using the following methods, annual rates and period:

Equipment

Furniture and fixtures

Computer equipment

Leasehold improvements

Declining balance and straight-line

Remaining lease term

Depreciation  expense,  which  is  recorded  in  the  consolidated  statement  of  comprehensive  loss,  is  allocated  to  the  appropriate  functional  expense
categories to which the underlying items of property, plant and equipment relate.

Identifiable intangible assets and amortization

Identifiable intangible assets with finite useful lives consist of in-process R&D acquired in business combinations, patents and trademarks. In-process
R&D acquired in business combinations is recognized at fair value at the acquisition date. Patents and trademarks are comprised of costs, including
professional fees incurred in connection with the filing of patents and the registration of trademarks for product marketing and manufacturing purposes,
net of related government grants, impairment losses, where applicable, and accumulated amortization. Identifiable intangible assets with finite useful
lives are amortized, from the time at which the assets are available for use, on a straight-line basis over their estimated useful lives of eight to fifteen
years  for  in-process  R&D  and  patents  and  ten  years  for  trademarks.  Amortization  expense,  which  is  recorded  in  the  consolidated  statement  of
comprehensive loss, is allocated to the appropriate functional expense categories to which the underlying identifiable intangible assets relate.

(tabular amounts in thousands of US dollars, except share/option/warrant and per share/option/warrant data and as otherwise noted)

Goodwill

Goodwill represents the excess of the purchase price over the fair values of the net assets of entities acquired at their respective dates of acquisition.
Goodwill is carried at cost less accumulated impairment losses. Goodwill is allocated to each cash-generating unit ("CGU") or group of CGUs that are
expected to benefit from the related business combination.

Impairment of assets

Items  of  property,  plant  and  equipment  and  identifiable  intangible  assets  with  finite  lives  subject  to  depreciation  or  amortization,  respectively,  are
reviewed  for  impairment  whenever  events  or  changes  in  circumstances  indicate  that  the  carrying  amounts  of  the  assets  may  not  be  recoverable.
Management is required to assess at each reporting date whether there is any indication that an asset may be impaired. Where such an indication exists,
the asset's recoverable amount is compared to its carrying value, and an impairment loss is recognized for the amount by which the asset's carrying
amount exceeds its recoverable amount. The recoverable amount is the higher of an asset's fair value less costs to sell and value in use. For the purpose
of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows, or CGU. In determining value in
use of a given asset or CGU, estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market
assessments  of  the  time  value  of  money  and  the  risks  specific  to  the  asset.  Impairment  losses  are  allocated  to  the  appropriate  functional  expense
categories to which the underlying identifiable intangible assets relate, and are recorded in the consolidated statement of comprehensive loss.

Items  of  property,  plant  and  equipment  and  amortizable  identifiable  intangible  assets  with  finite  lives  that  suffered  impairment  are  reviewed  for
possible reversal of the impairment if there has been a change, since the date of the most recent impairment test, in the estimates used to determine the
impaired asset's recoverable amount. However, an asset's carrying amount, increased due to the reversal of a prior impairment loss, must not exceed the
carrying amount that would have been determined, net of depreciation or amortization, had the original impairment not occurred.

Goodwill is not subject to amortization and instead is tested for impairment annually or more often if there is an indication that the CGU to which the
goodwill has been allocated may be impaired. Impairment is determined for goodwill by assessing whether the carrying value of a CGU, including the
allocated goodwill, exceeds its recoverable amount, which is the higher of fair value less costs to sell and value in use. In the event that the carrying
amount of goodwill exceeds its recoverable amount, an impairment loss is recognized in an amount equal to the excess. Impairment losses related to
goodwill are not subsequently reversed.

Share purchase warrants

Share purchase warrants are classified as liabilities when the Company does not have the unconditional right to avoid delivering cash to the holders in
the future. Each of the Company's share purchase warrants contains a written put option, arising upon the occurrence of a fundamental transaction, as
that term is defined in the share purchase warrants, including a change of control. As a result of the existence of these put options, and despite the fact
that the repurchase feature is conditional on a defined contingency, the share purchase warrants are required to be classified as a financial liability,
since such contingency could ultimately result in the transfer of assets by the Company.

The warrant liability is initially measured at fair value, and any subsequent changes in fair value are recognized as gains or losses through profit or
loss. Any transaction costs related to the share purchase warrants are expensed as incurred.

The warrant liability is classified as non-current, unless the underlying share purchase warrants will expire or be settled within 12 months from the end
of a given reporting period.

Employee benefits

Salaries and other short-term benefits

Salaries  and  other  short-term  benefit  obligations  are  measured  on  an  undiscounted  basis  and  are  recognized  in  the  consolidated  statement  of
comprehensive loss over the related service period or when the Company has a present legal or constructive obligation to make payments as a result of
past events and when the amount payable can be estimated reliably.

Post-employment benefits

108

Aeterna Zentaris Inc.
Notes to Consolidated Financial Statements
As at December 31, 2017 and December 31, 2016 and for the years ended December 31, 2017, 2016 and 2015

(tabular amounts in thousands of US dollars, except share/option/warrant and per share/option/warrant data and as otherwise noted)

The  Company's  subsidiary  in  Germany  maintains  defined  contribution  and  unfunded  defined  benefit  plans,  as  well  as  other  benefit  plans  for  its
employees.  For  defined  benefit  pension  plans  and  other  post-employment  benefits,  net  periodic  pension  expense  is  actuarially  determined  on  a
quarterly basis using the projected unit credit method. The cost of pension and other benefits earned by employees is determined by applying certain
assumptions,  including  discount  rates,  the  projected  age  of  employees  upon  retirement,  the  expected  rate  of  future  compensation  and  employee
turnover.

The employee future benefits liability is recognized at its present value, which is determined by discounting the estimated future cash outflows using
interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid and that have terms to maturity
approximating the terms of the related future benefit liability. Actuarial gains and losses that arise in calculating the present value of the defined benefit
obligation  are  recognized  in  other  comprehensive  loss,  net  of  tax,  and  simultaneously  reclassified  in  the  deficit  in  the  consolidated  statement  of
financial position in the year in which the actuarial gains and losses arise and without recycling to the consolidated statement of comprehensive loss in
subsequent periods.

For defined contribution plans, expenses are recorded in the consolidated statement of comprehensive loss as incurred–namely, over the period that the
related employee service is rendered.

Termination benefits

Termination benefits are recognized in the consolidated statement of comprehensive loss when the Company is demonstrably committed, without the
realistic possibility of withdrawal, to a formal detailed plan to terminate employment earlier than originally expected. Termination benefit liabilities
expected to be settled after 12 months from the end of a given reporting period are discounted to their present value, where material.

Financial instruments

The Company classifies its financial instruments in the following categories: "Financial assets at fair value through profit or loss ("FVTPL"); "Loans
and receivables"; "Financial liabilities at "FVTPL"; and "Other financial liabilities".

Financial  assets  and  liabilities  are  offset,  and  the  net  amount  is  reported  in  the  consolidated  statement  of  financial  position,  when  there  is  a  legally
enforceable  right  to  offset  the  recognized  amounts  and  there  is  an  intention  to  settle  on  a  net  basis  or  realize  the  asset  and  settle  the  liability
simultaneously.

(a) Classification

Financial assets at fair value through profit or loss

Financial  assets  at  FVTPL  are  financial  assets  held  for  trading.  Fair  value  is  defined  as  the  amount  at  which  the  financial  assets  could  be
exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. A financial asset is classified as at FVTPL if
the  instrument  is  acquired  or  received  as  consideration  principally  for  the  purpose  of  selling  in  the  short-term.  Financial  assets  at  FVTPL  are
classified as current assets if expected to be settled within 12 months from the end of a given reporting period; otherwise, the assets are classified
as non-current.

As at December 31, 2017 and 2016, the Company held no assets classified as financial assets at FVTPL.

Loans and receivables

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. Loans and
receivables are included in current assets, except for instruments with maturities greater than 12 months after the end of a given reporting period or
where restrictions apply that limit the Company from using the instrument for current purposes, which are classified as non-current assets.

The Company's loans and receivables are comprised of cash and cash equivalents, trade and other receivables and restricted cash equivalents.

(tabular amounts in thousands of US dollars, except share/option/warrant and per share/option/warrant data and as otherwise noted)

Financial liabilities at fair value through profit or loss

Financial liabilities at FVTPL are financial liabilities held for trading. A financial liability is classified as at FVTPL if the instrument is acquired or
incurred principally for the purpose of selling or repurchasing in the short-term or where the Company does not have the unconditional right to
avoid  delivering  cash  or  another  financial  asset  to  the  holders  in  certain  circumstances.  Financial  liabilities  at  FVTPL  are  classified  as  current
liabilities if required to be settled within 12 months from the end of a given reporting period; otherwise, the liabilities are classified as non-current.

Financial liabilities at FVTPL are currently comprised of the Company's warrant liability.

Other financial liabilities

Other financial liabilities include trade accounts payable and accrued liabilities, provision for restructuring and other non-current liabilities.

(b) Recognition and measurement

Financial assets at fair value through profit or loss

Financial assets at FVTPL are recognized on the settlement date, which is the date on which the asset is delivered to the Company. Financial assets
at FVTPL are initially recognized at fair value, and transaction costs are expensed immediately in the consolidated statement of comprehensive
loss. Financial assets at FVTPL are derecognized when the right to receive cash flows from the underlying investment have expired or have been
transferred and when the Group has transferred substantially all risks and rewards of ownership. Gains and losses arising from changes in the fair
value of financial assets at FVTPL are presented in the consolidated statement of comprehensive loss within finance income or finance costs in the
period in which they arise.

Loans and receivables

Loans and receivables are recognized on the settlement date and are measured initially at fair value and subsequently at amortized cost using the
effective interest rate method.

Financial liabilities at fair value through profit or loss

Financial  liabilities  at  FVTPL  are  recognized  on  the  settlement  date.  Financial  liabilities  at  FVTPL  are  initially  recognized  at  fair  value,  and
transaction costs are expensed immediately in the consolidated statement of comprehensive loss. Gains and losses arising from changes in the fair
value of financial liabilities at FVTPL are presented in the consolidated statement of comprehensive loss in the period in which they arise.

Other financial liabilities

Financial  instruments  classified  as  "Other  financial  liabilities"  are  measured  initially  at  fair  value  and  subsequently  at  amortized  cost  using  the
effective interest rate method.

(c) Impairment

Financial assets measured at amortized cost are reviewed for impairment at each reporting date. Where there is objective evidence that impairment
exists for a financial asset measured at amortized cost, an impairment charge equivalent to the difference between the asset's carrying amount and
the present value of estimated future cash flows is recorded in the consolidated statement of comprehensive loss. The expected cash flows exclude
future credit losses that have not been incurred and are discounted at the financial asset's original effective interest rate.

Impairment charges related to financial assets carried at amortized cost are reversed if, in a subsequent period, the amount of the impairment loss
decreases and the decrease can be related objectively to an event occurring after the impairment was recognized. However, the reversal cannot
result in a carrying amount of the financial asset that exceeds what the amortized cost would have been had the impairment not been recognized at
the date the impairment is reversed.

Common  shares  are  classified  as  equity.  Incremental  costs  that  are  directly  attributable  to  the  issuance  of  common  shares  and  stock  options  are
recognized as a deduction from equity, net of any tax effects.

Where  offerings  result  in  the  issuance  of  units  (where  each  unit  is  comprised  of  a  common  share  of  the  Company  and  a  share  purchase  warrant,
exercisable in order to purchase a common share or fraction thereof), proceeds received in connection with those offerings are allocated between Share
capital  and  Share  purchase  warrants  based  on  the  residual  method.  Proceeds  are  allocated  to  warrant  liability  based  on  the  fair  value  of  the  share
purchase warrants, and the residual amount of proceeds is allocated to Share capital. Transaction costs in connection with such offerings are allocated
to the liability and equity unit components in proportion to the allocation of proceeds.

Provisions

Provisions represent liabilities to the Company for which the amount or timing is uncertain. Provisions are recognized when the Company has a present
legal or constructive obligation as a result of past events, such as organizational restructuring, when it is probable that an outflow of resources will be
required to settle the obligation and where the amount can be reliably estimated. Provisions are not recognized for future operating losses.

Provisions are made for any contracts which are deemed onerous. A contract is onerous if the unavoidable costs of meeting the obligations under the
contract exceed the economic benefits expected to be received under it. Provisions for onerous contracts are measured at the present value of the lower
of  the  expected  cost  of  terminating  the  contract  and  the  expected  net  cost  of  continuing  with  the  contract.  Present  value  is  determined  based  on
expected  future  cash  flows  that  are  discounted  at  a  pre-tax  rate  that  reflects  current  market  assessments  of  the  time  value  of  money  and  the  risks
specific to the liability. The unwinding of the discount is recognized in finance costs.

Revenue recognition

Licensing revenues and multiple element arrangements

The Company is currently in a phase in which certain potential products are being further developed or marketed jointly with partners and licensees.
Existing licensing agreements usually involve one-time payments (upfront payments), payments for R&D services in the form of cost reimbursements,
milestone  payments  and  royalty  receipts  for  licensing  and  marketing  product  candidates.  Revenues  associated  with  those  multiple-element
arrangements are allocated to the various elements based on their relative fair value.

Agreements  containing  multiple  elements  are  divided  into  separate  units  of  accounting  if  certain  criteria  are  met,  including  whether  the  delivered
element has stand-alone value to the customer and whether there is objective and reliable evidence of the fair value of the undelivered obligation(s).
The consideration received is allocated among the separate units based on each unit's fair value, and the applicable revenue recognition criteria are
applied to each of the separate units.

License fees representing non-refundable payments received at the time of executing the license agreements are recognized as revenue upon signature
of the license agreements when the Company has no significant future performance obligations under a multiple element arrangement and collectibility
of  the  fees  is  probable.  When  there  are  future  performance  obligations  under  a  multiple  element  arrangement,  upfront  payments  received  at  the
beginning of licensing agreements are deferred and recognized as revenue on a systematic basis over the period during which the related services are
rendered and all obligations are performed.

Milestone payments

Milestone payments, which are generally based on developmental or regulatory events, are recognized as revenue when the milestones are achieved,
collectibility is assured, and when the Company has no significant future performance obligations in connection with the milestones.

Sales Commission

Revenues from sales commission are recognized when all the following conditions are satisfied:

the service provided;
the amount of revenue can be measured reliably; and
it is probable that the economic benefits associated with the transaction will flow to the Company.

The Company is responsible for promoting some products. Therefore, there is no continuing involvement following the patient starting the treatment
and buying the products.

Share-based compensation costs

The Company operates an equity-settled share-based compensation plan under which the Company receives services from directors, senior executives,
employees and other collaborators as consideration for equity instruments of the Company.

The Company accounts for all forms of share-based compensation using the fair value-based method. Fair value of stock options is determined at the
date of grant using the Black-Scholes option pricing model, which includes estimates of the number of awards that are expected to vest over the vesting
period. Where granted share options vest in installments over the vesting period (defined as graded vesting), the Company treats each installment as a
separate share option grant. Share-based compensation expense is recognized over the vesting period, or as specified vesting conditions are satisfied,
and credited to Other Capital.

Any  consideration  received  by  the  Company  in  connection  with  the  exercise  of  stock  options  is  credited  to  Share  Capital.  Any  Other  Capital
component of the share-based compensation is transferred to Share Capital upon the issuance of shares.

Current and deferred income tax

Income  tax  on  profit  or  loss  comprises  current  and  deferred  tax.  Tax  is  recognized  in  profit  or  loss,  except  that  a  change  attributable  to  an  item  of
income or expense recognized as other comprehensive loss or directly in equity is also recognized directly in other comprehensive loss or directly in
equity.  Management  periodically  evaluates  positions  taken  in  tax  returns  with  respect  to  situations  in  which  applicable  tax  regulation  is  subject  to
interpretation and establishes provisions where appropriate on the basis of amounts expected to be paid to the tax authorities.

The current income tax charge is calculated in accordance with tax rates and laws that have been enacted or substantively enacted by the reporting date
in the countries where the Company's subsidiaries operate and generate taxable income.

Deferred income tax is recognized on temporary differences (other than, where applicable, temporary differences associated with unremitted earnings
from foreign subsidiaries and associates to the extent that the investment is essentially permanent in duration, and temporary differences associated
with the initial recognition of goodwill) arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated financial
statements and on unused tax losses or R&D non-refundable tax credits in the Group. Deferred income tax is determined using tax rates and laws that
have been enacted or substantively enacted by the reporting date.

Deferred income tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the temporary
differences can be utilized.

Deferred income tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against current tax liabilities
and when the deferred income taxes assets and liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity
or different taxable entities where there is an intention to settle the balances on a net basis.

Research and development costs

Research  costs  are  expensed  as  incurred.  Development  costs  are  expensed  as  incurred,  except  for  those  that  meet  generally  accepted  criteria  for
deferral,  in  which  case  the  costs  are  capitalized  and  amortized  to  operations  over  the  estimated  period  of  benefit.  No  development  costs  have  been
capitalized during any of the periods presented.

Discontinued operations

(tabular amounts in thousands of US dollars, except share/option/warrant and per share/option/warrant data and as otherwise noted)

A discontinued operation is a component of the Company that has been disposed of, or is classified as held for sale, and represents a separate major
line  of  business  or  geographical  area  of  operations  and/or  is  part  of  a  single  co-ordinated  plan  to  dispose  of  a  separate  major  line  of  business  or
geographical area of operations. Classification as a discontinued operation occurs upon the earlier of the disposal of the operation (or disposal group)
or the date at which the operation meets the criteria for classification as held for sale. When an operation is classified as discontinued, comparative
statements of comprehensive loss and cash flows are presented as if the operations had been discontinued at the beginning of the earliest comparative
period presented.

Net (loss) income per share

Basic net (loss) income per share is calculated using the weighted average number of common shares outstanding during the year.

Diluted net (loss) income per share is calculated based on the weighted average number of common shares outstanding during the year, plus the effects
of dilutive common share equivalents, such as stock options and share purchase warrants. This method requires that diluted net (loss) income per share
be calculated using the treasury stock method, as if all common share equivalents had been exercised at the beginning of the reporting period, or period
of issuance, as the case may be, and that the funds obtained thereby were used to purchase common shares of the Company at the average trading price
of the common shares during the period.

3 Critical accounting estimates and judgments

The preparation of consolidated financial statements in accordance with IFRS requires management to make judgments, estimates and assumptions that
affect the reported amounts of the Company's assets, liabilities, revenues, expenses and related disclosures. Judgments, estimates and assumptions are
based  on  historical  experience,  expectations,  current  trends  and  other  factors  that  management  believes  to  be  relevant  at  the  time  at  which  the
Company's consolidated financial statements are prepared.

Management  reviews,  on  a  regular  basis,  the  Company's  accounting  policies,  assumptions,  estimates  and  judgments  in  order  to  ensure  that  the
consolidated financial statements are presented fairly and in accordance with IFRS. Revisions to accounting estimates are recognized in the period in
which the estimates are revised and in any future periods affected.

(a) Critical accounting estimates and assumptions

Critical accounting estimates and assumptions are those that have a significant risk of causing material adjustment and are often applied to matters
or outcomes that are inherently uncertain and subject to change. As such, management cautions that future events often vary from forecasts and
expectations and that estimates routinely require adjustment.

The  following  discusses  the  most  significant  accounting  estimates  and  assumptions  that  the  Company  has  made  in  the  preparation  of  the
consolidated financial statements.

Fair value of the warrant liability and stock options

Determining  the  fair  value  of  the  warrant  liability  and  stock  options  requires  judgment  related  to  the  selection  of  the  most  appropriate  pricing
model, the estimation of stock price volatility and the expected term of the underlying instruments. Any changes in the estimates or inputs utilized
to  determine  fair  value  could  result  in  a  significant  impact  on  the  Company's  future  operating  results,  liabilities  or  other  components  of
shareholders' equity. Fair value assumptions used are described in note 14 - Warrant liability and 16 - Share capital.

Goodwill impairment

The annual impairment assessment related to goodwill requires to estimate the recoverable amount, which has been determined using fair value
less  costs  of  disposal.  This  evaluation  is  based  on  estimates  that  are  derived  from  current  market  capitalization  and  on  other  factors,  including
assumptions related to relevant industry-specific market analyses and potential costs to dispose. The Company also concluded that there was only
one CGU as management monitors goodwill on an overall entity basis. Future events, including a significant reduction in the Company's share
price, could cause the assumptions utilized in the impairment tests to change, resulting in a potentially adverse effect on the Company's future
results due to increased impairment charges.

(tabular amounts in thousands of US dollars, except share/option/warrant and per share/option/warrant data and as otherwise noted)

Employee future benefits

The determination of expenses and obligations associated with employee future benefits requires the use of assumptions, such as the discount rate
to  measure  obligations,  the  projected  age  of  employees  upon  retirement,  the  expected  rate  of  future  compensation  and  estimated  employee
turnover. Because the determination of the cost and obligations associated with employee future benefits requires the use of various assumptions,
there is measurement uncertainty inherent in the actuarial valuation process. Actual results will differ from results that are estimated based on the
aforementioned assumptions. Additional information is included in note 18 - Employee future benefits.

Income taxes

The estimation of income taxes includes evaluating the recoverability of deferred tax assets based on an assessment of Group entities' ability to
utilize the underlying future tax deductions against future taxable income prior to expiry of those deductions. Management assesses whether it is
probable that some or all of the deferred income tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon
the  generation  of  future  taxable  income,  which  in  turn  is  dependent  upon  the  successful  commercialization  of  the  Company's  products.  To  the
extent  that  management's  assessment  of  any  Group  entity's  ability  to  utilize  future  tax  deductions  changes,  the  Company  would  be  required  to
recognize more or fewer deferred tax assets, and future income tax provisions or recoveries could be affected. Additional information is included
in note 20 - Income taxes.

(b) Critical judgments in applying the Company's accounting policies

Revenue recognition

Management's  assessments  related  to  the  recognition  of  revenues  related  to  arrangements  containing  multiple  elements  are  based  on  judgment.
Judgment  is  necessary  to  identify  separate  units  of  accounting  and  to  allocate  related  consideration  to  each  separate  unit  of  accounting.  Where
deferral of upfront payments or license fees is deemed appropriate, subsequent revenue recognition is often determined based upon the assessment
of the Company's continuing involvement in the arrangement, the benefits expected to be derived by the customer and, where applicable, expected
patent lives. Additional information is included in note 5 - Deferred revenues related to licensing arrangements and co-development agreement.

4 Recent accounting pronouncements

Accounting standards adopted without impact

In January 2016, the IASB issued amendments to IAS 12, Income taxes to clarify the requirements for recognizing deferred tax assets on unrealized
losses. The amendments clarify the accounting for deferred tax where an asset is measured at fair value and that fair value is below the asset's tax base.
They  also  clarify  certain  other  aspects  of  accounting  for  deferred  tax  assets.  The  amendments  are  effective  from  January  1,  2017.  The  Company
concluded that these amendments have no impact on the Company's consolidated financial statements.

In  January  2016,  the  IASB  issued  an  amendment  to  IAS  7,  Statement  of  cash  flows,  introducing  an  additional  disclosure  that  will  enable  users  of
financial  statements  to  evaluate  changes  in  liabilities  arising  from  financing  activities.  The  amendment  is  part  of  the  IASB's  Disclosure  Initiative,
which  continues  to  explore  how  financial  statement  disclosure  can  be  improved.  The  amendment  is  effective  from  January  1,  2017.  The  Company
believes that the information provided in note 14 is sufficient to meet this new requirement.

Accounting standards not yet adopted

The final version of IFRS 9, Financial Instruments ("IFRS 9"), was issued by the IASB in July 2014 and will replace IAS 39, Financial Instruments:
Recognition and Measurement ("IAS  39").  IFRS  9  introduces  a  model  for  classification  and  measurement,  a  single,  forward-looking  expected  loss
impairment  model  and  a  substantially  reformed  approach  to  hedge  accounting.  The  new  single,  principle-based  approach  for  determining  the
classification of financial assets is driven by cash flow characteristics and the business model in which an asset is held. The new model also results in a
single impairment

model  being  applied  to  all  financial  instruments,  which  will  require  more  timely  recognition  of  expected  credit  losses.  It  also  includes  changes  in
respect of an entity's own credit risk in measuring liabilities elected to be measured at fair value, so that gains caused by the deterioration of an entity's
own  credit  risk  on  such  liabilities  are  no  longer  recognized  in  profit  or  loss.  IFRS  9,  which  is  to  be  applied  retrospectively,  is  effective  for  annual
periods beginning on or after January 1, 2018. There are amendments to IFRS 7 which require additional disclosures on transition from IAS 39 to IFRS
9. These amendments are effective upon adoption of IFRS 9. The Company is currently assessing the impact, if any, that these new standards may have
on the Company's consolidated financial statements.

In May 2014, the IASB issued IFRS 15, Revenue from Contracts with Customers ("IFRS 15"). The objective of this new standard is to provide a single,
comprehensive  revenue  recognition  framework  for  all  contracts  with  customers  to  improve  comparability  of  financial  statements  of  companies
globally. This new standard contains principles that an entity will apply to determine the measurement of revenue and timing of when it is recognized.
The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity
expects to be entitled to receive in exchange for those goods or services. This new standard is effective for annual periods beginning on or after January
1, 2018. The Company is currently assessing the impact, if any, that these amendments may have on the Company's consolidated financial statements.

In November 2016, the IFRS Interpretations Committee issued an Interpretation on how to determine the date of the transaction when applying IAS 21,
The  Effects  of  Changes  in  Foreign  Exchange  Rates.  The  Interpretation  applies  where  an  entity  either  pays  or  receives  consideration  in  advance  for
foreign  currency-denominated  contracts.  The  Interpretation  provides  guidance  for  when  a  single  payment/receipt  is  made,  as  well  as  for  situations
where multiple payments/receipts are made. The Interpretation is effective for annual periods beginning on or after January 1, 2018. The Company is
currently assessing the impact, if any, that these amendments may have on the Company's consolidated financial statements.

In December 2016, IFRIC 22, "Foreign Currency Transactions and Advance Consideration", was issued. IFRIC 22 addresses how to determine the date
of the transaction for the purpose of determining the exchange rate to use on initial recognition of the related asset, expense or income (or part of it)
and on the derecognition of a non-monetary asset or non-monetary liability arising from the payment or receipt of advance consideration in a foreign
currency.  IFRIC  22  is  effective  for  annual  periods  beginning  on  or  after  January  1,  2018.  Early  adoption  is  permitted.  The  company  is  currently
assessing the impact, if any, that this new standard may have on the Company's consolidated financial statements.

In January 2016, the IASB issued IFRS 16, Leases ("IFRS 16"), which supersedes IAS 17, Leases, and the related interpretations on leases: IFRIC 4,
Determining Whether an Arrangement Contains a Lease; Standard Interpretations Committee ("SIC") 15, Operating Leases - Incentives; and SIC 27,
Evaluating the Substance of Transactions in the Legal Form of a Lease. IFRS 16 is effective for annual periods beginning on or after January 1, 2019,
with earlier adoption permitted for companies that also apply IFRS 15. The Company is currently assessing the impact, if any, that this new standard
may have on the Company's consolidated financial statements.

In June 2017, FRIC 23, "Uncertainty over Income Tax Treatment", was issued. IFRIC 23 provides guidance on how to value uncertain income tax
positions  based  on  the  probability  of  whether  the  relevant  tax  authorities  will  accept  the  company's  tax  treatments.  A  company  is  to  assume  that  a
taxation  authority  with  the  right  to  examine  any  amounts  reported  to  it  will  examine  those  amounts  and  will  have  full  knowledge  of  all  relevant
information when doing so. IFRIC 23 is effective for annual periods beginning on or after January 1, 2019.  The company is currently assessing the
impact, if any, that this new standard may have on the Company's consolidated financial statements.

5 Deferred revenues related to licensing arrangements and co-development agreement

Zoptrex™ License Agreements

On July 1, 2016, the Company entered into a license agreement (the "Cyntec License Agreement") with Cyntec Co., Ltd. ("Cyntec"), an affiliate of
Orient EuroPharma Co., Ltd. ("OEP") for Zoptrex™ (zoptarelin doxorubicin) for the initial indication of endometrial cancer. Under the terms of the
Cyntec License Agreement, the Company was paid a non-refundable upfront cash payment (the "License Fee") of 500,000 Euros in consideration for
the license to Cyntec of the Company's intellectual property related to Zoptrex™ and the grant to Cyntec of the right to commercialize Zoptrex™ in a
territory consisting of Taiwan and nine countries in southeast Asia (the "OEP Territory"). Cyntec has also agreed to make additional payments to the
Company  upon  achieving  certain  pre-established  regulatory  and  commercial  milestones.  Furthermore,  the  Company  will  receive  royalties  based  on
future net sales of Zoptrex™ in the OEP Territory. Cyntec will be responsible for the development, registration, reimbursement and commercialization
of the product in the OEP Territory. The Company also entered into related Technology Transfer and Supply Agreements with another affiliate of OEP,
pursuant to which the Company will transfer to such affiliate the technology necessary to permit the affiliate to manufacture finished Zoptrex™ using
quantities of the active pharmaceutical agreement purchased from the Company pursuant to the Supply Agreement.

On December  1,  2014,  the  Company  entered  into  an  exclusive  master  collaboration  agreement  ("Master  Collaboration  Agreement"),  a  technology
transfer and technical assistance agreement ("Tech Transfer Agreement") and a license agreement ("Sinopharm License Agreement") with Sinopharm
A-Think  Pharmaceuticals  Co.,  Ltd.  ("Sinopharm")  for  the  development,  manufacture  and  commercialization  of  Zoptrex™  in  all  human  uses,  in  the
People's Republic of China, including Hong Kong and Macau (collectively, the "Sinopharm Territory"). Under the terms of the TTA, Sinopharm made
a one-time, non-refundable payment (the "Transfer Fee") of $1,000,000 to the Company in consideration for the transfer of technical documentation
and materials, know-how and technical assistance services. Additionally, pursuant to the Sinopharm License Agreement, the Company is entitled to
receive  additional  consideration  upon  achieving  certain  milestones,  including  the  occurrence  of  certain  regulatory  and  commercial  events  in  the
Sinopharm Territory. Furthermore, the Company is entitled to royalties on future net sales of Zoptrex™ in the Sinopharm Territory.

The Company has continuing involvement in the aforementioned arrangements, including the transfer of documentation, know-how and materials, as
well as the provision of technical assistance, such as quality systems implementation, analytical and stability testing, territory-specific development
initiatives, and other services.

The  Company  has  applied  the  provisions  of  IAS  18,  Revenue  ("IAS  18"),  and  has  determined  that  all  deliverables  and  performance  obligations
contemplated by the agreements with Cyntec/OEP and Sinopharm should be accounted for as a single unit of accounting, limited to amounts that are
not  contingent  upon  the  delivery  of  additional  items  or  the  meeting  of  other  specified  performance  conditions  which  are  not  known,  probable  or
estimable at the time at which the agreements with OEP and Sinopharm were entered into.

The Company has deferred the non-refundable License and Transfer Fees and is amortizing the related payment as revenue on a straight-line basis over
the period during which the aforementioned services are rendered and obligations are performed.

In  determining  the  period  over  which  the  License  and  Transfer  Fee  revenues  are  to  be  recognized,  the  Company  concluded  that  its  significant
continuing  involvement  in  the  aforementioned  agreements  will  span  approximately  until  the  end  of  December 2018.  However,  the  Company  may
adjust  the  amortization  period  based  on  appropriate  facts  and  circumstances  not  yet  known,  that  would  significantly  change  the  duration  of  the
Company's continuing involvement and performance obligations or benefits expected to be derived by OEP and Sinopharm.

Future  milestone  payments  will  be  recognized  as  revenue  individually  and  in  full  upon  the  actual  achievement  of  the  related  milestone,  given  the
substantive nature of each milestone. Lastly, upon initial commercialization and sale of the developed product, the Company will recognize royalty
revenues as earned, based on the contractual percentage applied to the actual net sales achieved by OEP or Sinopharm, as per the license agreement.

On May 1, 2017, the Company announced that the ZoptEC pivotal Phase 3 clinical study of Zoptrex™ in women with locally advanced, recurrent or
metastatic endometrial cancer did not achieve its primary endpoint of demonstrating a statistically significant increase in the median period of overall
survival of patients treated with Zoptrex™ as compared to

patients treated with doxorubicin. The results of the study are not supportive to pursue regulatory approval. Based on this outcome, the Company does
not anticipate conducting clinical trials of Zoptrex™ with respect to any other indications.

The Company currently has deferred revenues at December 31, 2017 of $541,000 relating to non-refundable upfront payments it previously received
for  licensing  and  technology  transfer  arrangements  that  it  entered  into  with  respect  to  the  development  of  Zoptrex™  in  various  territories.  Due  to
events that occurred in 2018, the Company does not anticipate development of Zoptrex™ under the licensing agreements, therefore the Company's
remaining carrying amount of deferred revenues will be recognized in the first quarter of 2018 as income.

Ergomed Agreement

On April 10, 2013, the Company entered into a co-development and revenue-sharing agreement ("CDRSA") with Ergomed Clinical Research Limited
("Ergomed"),  pursuant  to  which  Ergomed  agreed  to  assist  the  Company  in  the  clinical  development  program  for  Zoptrex™  for  the  purpose  of
maximizing the commercialization potential of Zoptrex™ with the ultimate aim of selling or licensing Zoptrex™. Concurrently with the execution of
the CDRSA, the Company entered into a master services agreement ("MSA") with Ergomed for a Phase 3 clinical trial of Zoptrex™ in endometrial
cancer, pursuant to which Ergomed provided clinical development services with respect to the co-development initiative referred to above.

While  Ergomed  will  not  directly  contribute  any  cash  proceeds  towards  the  completion  of  the  activities  contemplated  by  the  CDRSA,  Ergomed,  as
primary supplier of a substantial portion of Zoptrex™ related clinical and regulatory activities, will contribute to the overall funding of the initiative
via  the  application  of  a  30%  discount  from  the  costs  set  forth  in  the  MSA  until  the  cumulative  total  of  such  reductions  reaches  a  maximum  of
$10,000,000. As of December 31, 2017 the amount not charged by Ergomed totaled approximately 9,900,000. Ergomed will be entitled to receive an
agreed upon single-digit percentage of any future net income (as defined in the CDRSA) or other proceeds related to the licensing of Zoptrex™ in
endometrial cancer indication, up to a specified maximum amount.

The  Company  recognizes  R&D  costs  associated  with  the  CDRSA  and  MSA  net  of  the  30%  discount,  as  services  are  rendered  by  Ergomed  in  the
consolidated  statement  of  comprehensive  loss.  During  the  years  ended  December  31,  2017,  2016  and  2015,  the  Company  expensed  a  total  of
$1,117,000, $4,436,000, $7,140,000, respectively, pursuant to the CDRSA and MSA.

As mentioned previously, the results of the Zoptec pivotal Phase 3 clinical study of Zoptrex™ are not supportive to pursue regulatory approval and
consequently the Company does not anticipate incurring additional R&D costs associated with the CDRSA and MSA.

On October 9, 2015, the Company's Board of Directors approved a plan to restructure the Company's finance and accounting operations and to close
the Company's Quebec City office (the "2015 Corporate Restructuring"). The Company transferred all functions performed by the five employees in its
Quebec City office to other personnel. As of December 31, 2016, the Corporate Restructuring was completed.

In July 2017, the Company's subsidiary located in Germany and its Works Council approved the Company's restructuring program (the "2017 German
Restructuring"), creating a constructive obligation from that date. The 2017 German Restructuring is a consequence of the negative Phase 3 clinical
trial results of ZoptrexTM announced  on  May  1,  2017  and  the  related  impact  on  the  Company's  product  pipeline.  This  is  also  part  of  the  continued
strategy  to  transition  Aeterna  Zentaris  into  a  commercially  operating  specialty  biopharmaceutical  organization.  The  goal  of  the  2017  German
Restructuring is to reduce to a minimum the Company R&D activities and is expected to result in the termination of approximately 24 employees of
the German subsidiary.

The Company started implementing the 2017 German Restructuring in the fourth quarter of 2017, with staff departures expected to be completed over
a period of approximately 18 months. Total initial restructuring costs associated with the 2017 German Restructuring include severance accruals and
other  directly  related  costs  ($2,002,000)  and  an  onerous  lease  provision  ($1,113,000),  which  has  been  recorded  as  follows  in  the  accompanying
consolidated statement of comprehensive loss: $2,644,000 in R&D costs, $275,000 in General and administrative ("G&A") expenses and $196,000 in
selling expenses. These estimated costs may vary as a result of changes in the underlying assumptions applied thereto, including but not limited to, the
time needed to sublease the unused premises. Most of the restructuring accruals are expected to be paid in the financial year ending December 31,
2018.

The changes in the Company's provision for restructuring costs can be summarized as follows:

Based on United States Treasury Government Bond interest rates with a term that is consistent with the expected life of the warrants.

Based on the historical volatility of the Company's stock price over the most recent period consistent with the expected life of the warrants, as well as on future expectations.

Based upon time to expiry from the reporting period date.

The Company has not paid dividends and it does not intend to pay dividends in the foreseeable future.

For the March 2015 Series A Warrants, the inputs and assumptions applied to the Black-Scholes option pricing model have been further adjusted to take into consideration the value
attributed to certain anti-dilution provisions. Specifically, the weighted average exercise price is subject to adjustment (see note 16 - Share capital).

For the November 2016 Warrants, the Company reduced the fair value of these warrants to take into consideration the fair value of the $10 call option, which was also calculated
using the Black-Scholes pricing model. (see note 16 - Share capital).

Series B Warrants

In addition to the availability of standard cashless exercise provisions, the Series B Warrants (defined and discussed in note 16 - Share capital) were
entitled  to  be  exercised  on  an  alternate  cashless  basis  in  accordance  with  their  terms.  Such  an  exercise  permits  the  holder  to  obtain  a  number  of
common  shares  equal  to:  200%  of  (i)  the  total  number  of  common  shares  with  respect  to  which  the  Series  B  Warrant  was  then  being  exercised
multiplied by (ii) 81.00 divided by (iii) 85% of the quotient of (A) the sum of the per share volume weighted average price ("VWAP") of the common
share for each of the five lowest trading days during the fifteen trading day period ending on and including the trading day immediately prior to the
applicable Exercise Date, divided by (B) five, less (iv) the total number of common shares with respect to which the Series B Warrant is then being
exercised.

Exercises of Series B Warrants on an alternate cashless basis resulted in the issuance of a substantially larger number of the Company's common shares
than would have been otherwise issued following a standard cash or cashless exercise of the Series B Warrants.

Management has determined that, in light of the alternate cashless exercise feature and of actual Series B Warrant exercises since original issuance,
application  of  the  Black-Scholes  option  pricing  model  did  not  appropriately  reflect  the  fair  value  of  the  Series  B  Warrants  outstanding  at  a  given
statement of financial position date. Instead, management has determined that the application of an intrinsic valuation method is more representative of
the market value of the Series B Warrants.

The 8,064 Series B Warrants remaining on December 31, 2015 expired on September 12, 2016 without having been exercised.

(tabular amounts in thousands of US dollars, except share/option/warrant and per share/option/warrant data and as otherwise noted)

16 Share capital

The Company has an unlimited number of authorized common shares (being voting and participating shares) with no par value, as well as an unlimited
number of preferred, first and second ranking shares, issuable in series, with rights and privileges specific to each class, with no par value.

Share consolidation

The 655,984,512 common shares issued and outstanding immediately prior to the Share Consolidation, which became legally effective on November
17, 2015, were consolidated into 6,559,846 common shares (the "Post-Consolidation Shares"). The Post-Consolidation Shares began trading on each of
the TSX and NASDAQ at the opening of markets on November 20, 2015. The number of outstanding stock options and share purchase warrants were
adjusted on the same basis with proportionate adjustments being made to each stock option and share purchase warrant exercise price.

All  share,  option  and  share  purchase  warrant  and  per  share,  option  and  share  purchase  warrant  data  have  been  retroactively  adjusted  in  these
consolidated financial statements to reflect and give effect to the Share Consolidation as if it occurred at the beginning of the earliest period presented.

Common shares issued in connection with "At-the-Market" ("ATM") drawdowns

April 2016 ATM Program

On April 1, 2016, the Company entered into an ATM sales agreement (the "April 2016 ATM Program"), under which the Company was able, at its
discretion and from time to time, to sell up to 3 million common shares through ATM issuances on the NASDAQ for aggregate gross proceeds of up to
approximately $10 million. The April 2016 ATM Program provides that common shares were to be sold at market prices prevailing at the time of sale
and, as a result, prices varied.

Between April  1,  2016  and  March  24,  2017,  the  Company  issued  a  total  of  1,706,968  common  shares  under  the  April  2016  ATM  Program  at  an
average issuance price of $3.52 per share for aggregate gross proceeds of $6.0 million less cash transaction costs of $190,000 and previously deferred
financing costs of $225,000.

March 2017 ATM Program

On March 28, 2017, the Company commenced a new ATM offering pursuant to its existing ATM Sales Agreement, dated April 1, 2016, under which
the  Company  was  able,  at  its  discretion,  from  time  to  time,  to  sell  up  to  a  maximum  of  3  million  common  shares  through  ATM  issuances  on  the
NASDAQ,  up  to  an  aggregate  amount  of  $9.0  million  (the  "March  2017  ATM  Program").  The  common  shares  were  to  be  sold  at  market  prices
prevailing at the time of the sale of the common shares and, as a result, sale prices varied.

Between March  28,  2017  and  April  18,  2017,  the  Company  issued  a  total  of  597,994  common  shares  under  the  March 2017  ATM  Program  at  an
average issuance price of $2.97 per share for aggregate gross proceeds of $1,780,000 less cash transaction costs of $55,000 and previously deferred
financing costs of $65,000.

April 2017 ATM Program

On April 27, 2017, the Company entered into a New ATM Sales Agreement and filed with the Securities and Exchange Commission (the "SEC") a
prospectus supplement (the "April 2017  ATM  Prospectus  Supplement"  or  "April  2017  ATM  Program")  related  to  sales  and  distributions  of  up  to  a
maximum of 2,240,000 common shares through ATM issuances on the NASDAQ, up to an aggregate amount of $6.9 million under the New ATM
Sales Agreement. The common shares will be sold at market prices prevailing at the time of the sale of the common shares and, as a result, prices may
vary.  The  New  ATM  Sales  Agreement  and  the  April  2017  ATM  Program  superseded  and  replaced  the  March  2017  ATM  Program,  which  itself
superseded and replaced the April 2016 ATM Program. The April 2017 ATM Prospectus Supplement supplements the base prospectus included in the
Company's Shelf Registration Statement on Form F-3, as amended (the "2017 Shelf Registration Statement"), which was declared effective by the SEC
on April  27,  2017.  The  2017  Shelf  Registration  Statement  allows  us  to  offer  up  to  $50 million  of  common  shares  and  is  effective  for  a  three-year
period.

(tabular amounts in thousands of US dollars, except share/option/warrant and per share/option/warrant data and as otherwise noted)

Between May 30, 2017 and December 31, 2017, the Company issued a total of 1,805,758 common shares under the April 2017 ATM Program at an
average issuance price of $1.71 per share for aggregate gross proceeds of $3,761,000 less cash transaction costs of $115,000 and previously deferred
financing  costs  of  $285,000.  Because  of  these  issuances,  the  exercise  price  of  the  Series  A  warrants  issued  in  March 2015  was  adjusted  to  $1.07
pursuant to the anti-dilution provisions contained in such warrants.

Public offerings

March 2015 Offering

On March 11, 2015, the Company completed a public offering of 596,775 units (the "Units"), with each Unit consisting of either one common share or
one pre-funded warrant to purchase one common share ("Series C Warrant"), 0.75 of a warrant to purchase one common share ("Series A Warrant")
and 0.50 of a warrant to purchase one common share ("Series B Warrant"), at a purchase price of $62.00 per Unit (the "March 2015 Offering").

Total gross cash proceeds raised through the March 2015 Offering amounted to $37,000,000, less cash transaction costs of $2,560,000 and previously
deferred transaction costs of $7,000.

The  Series  A  Warrants  were  exercisable  during  a  five-year  term  at  an  initial  exercise  price  of  $81.00  per  share,  and  the  Series  B  Warrants  were
exercisable during an 18-month term at an initial exercise price of $81.00 per share. The Series A Warrants are and the Series B Warrants were subject
to certain anti-dilution provision and may at any time be exercised on a standard cashless basis and, in addition, the Series B Warrants were exercisable
on  an  alternate  net  cashless  basis.  The  exercise  of  Series  B  Warrants  performed  on  an  alternate  net  cashless  basis  resulted  in  the  issuance  of  a
substantially larger number of the Company's common shares than otherwise would be issued following a standard cash or cashless exercise. See also
note 14 - Warrant liability. The remaining 8,064 Series B Warrants expired September 12, 2016.

Between May  26,  2015  and  December  31,  2015,  290,318  of  the  Series  B  Warrants  were  exercised  on  an  alternate  cashless  basis,  resulting  in  the
issuance of 5,670,118 common shares.

The Company estimated the fair value attributable to the Series A and Series B warrants as of the date of grant by applying the Black-Scholes pricing
model, to which the following assumptions were applied: Series A warrants: a risk-free annual interest rate of 1.59%, an expected volatility of 95.11%,
an expected life of 5 years and a dividend yield of 0.0%; Series B warrants: a risk-free annual interest rate of 0.47%, an expected volatility of 97.34%,
an expected life of 18 months and a dividend yield of 0.0%. As a result, on March 11, 2015, the total fair value of the share purchase warrants was
estimated at $20,980,000.

The Series C Warrants were offered in the March 2015 Offering to investors whose purchase of Units would have resulted in their beneficially owning
more than an "initial beneficial ownership limitation" of either 4.9% or 9.9% of our common shares following the offering. The Series C Warrants,
which were exercisable immediately upon issuance and for a period of five years at an exercise price of $62.00 per share, were fully exercised between
March 23, 2015 and June 5, 2015. Total gross proceeds payable to the Company in connection with the exercise of the Series C Warrants were pre-
funded by investors and therefore were included in the proceeds of the offering. No additional consideration was required to be paid to the Company
upon exercise of the Series C Warrants.

Total  gross  proceeds  of  the  March  2015  Offering  were  allocated  as  follows:  $20,980,000  was  allocated  to  the  warrant  liability,  $9,296,000  was
allocated to pre-funded warrants, and the balance of $6,724,000 was allocated to Share capital. Transaction costs were allocated to the liability and
equity components in proportion to the allocation of proceeds. As such, an amount of $1,451,000 was allocated to the warrant liability and immediately
recognized in general and administrative expenses in the consolidated statement of comprehensive loss, an amount of $473,000 was allocated to Share
capital and an amount of $643,000 was allocated to pre-funded warrants. Upon exercise of the Series C Warrants, the net proceeds initially allocated to
the pre-funded warrants were re-allocated to Share capital.

In connection with the March 2015 Offering, the holders of 211,230 of the 219,000 then outstanding warrants issued by the Company in connection
with  public  offerings  completed  in  November  2013  and  January  2014  entered  into  an  amendment  agreement  that  caused  such  previously  issued
warrants to expire and terminate. The Company made a cash payment in the aggregate amount of $5,703,000 out of the proceeds of the March 2015
Offering as consideration to the relevant

warrantholders  in  exchange  for  the  latter  agreeing  to  the  aforementioned  amendment.  Upon  expiry  of  the  warrants  in  question,  the  Company
recognized  a  gain  of  $5,865,000  and  derecognized  the  expired  warrants.  The  gain  on  derecognition  was  recorded,  net  of  the  aforementioned
amendment  fee,  within  finance  income  in  the  accompanying  consolidated  statement  of  comprehensive  loss.  For  holders  of  the  remaining  7,770
outstanding warrants issued by the Company in connection with the November 2013 and the January 2014 offerings who did not enter into a warrant
amendment agreement, the exercise price of the corresponding warrants was reduced to $14.00 per share in accordance with the terms thereof.

December 2015 Offering

On December 14, 2015, the Company completed a public offering of 3,000,000 common shares at a purchase price of $5.54 per share and 2,100,000
warrants to purchase one common share at a purchase price of $0.01 per warrant (the "December 2015 Offering").

In connection with the December 2015 Offering, the Company granted the underwriter a 45-day over-allotment option to separately acquire up to an
additional 330,000 common shares at the same purchase price of $5.54 per share and/or up to an additional 231,000 warrants at the same purchase
price of $0.01 per warrants. The underwriter exercised its option in full with respect to the 231,000 warrants for market stabilization purposes but did
not exercise any of its option in respect of common shares.

Total gross cash proceeds raised through the December 2015 Offering amounted to $16,650,000, less cash transaction costs of $1,638,000.

The warrants are exercisable for a period of five years at an exercise price of $7.10 per share. Upon complete exercise for cash, these warrants would
result in the issuance of an aggregate of 2,331,000 common shares that would generate additional proceeds for an amount of $16,550,100. However,
those warrants may at any time be exercised on a "net" or "cashless" basis.

The Company estimated the fair value attributable to the warrants as of the date of grant by applying the Black-Scholes pricing model, to which the
following  assumptions  were  applied:  a  risk-free  annual  interest  rate  of  1.68%,  an  expected  volatility  of  107.57%,  an  expected  life  of  5 years and a
dividend yield of 0.00%. As a result, on December 14, 2015, the total fair value of the share purchase warrants was estimated at $7,698,000.

Total gross proceeds of the December 2015 Offering were allocated as follows: $7,698,000 was allocated to the warrant liability and $8,952,000 was
allocated to Share capital. Transaction costs were allocated to the liability and equity components in proportion to the allocation of proceeds. As such,
an amount of $757,000 was allocated to the warrant liability and immediately recognized in general and administrative expenses in the consolidated
statement of comprehensive loss, an amount of $881,000 was allocated to Share capital.

In connection with the December 2015 Offering and in accordance with the anti-dilution provisions, the exercise prices of the January 2014 and March
2015  Series  A  and  Series  B  warrants  were  adjusted  to  $0.00  and  $4.95,  respectively.  The  remaining  January  2014  Warrants  were  exercised  on
December 30, 2015 and no longer remain outstanding.

November 2016 Offering

On November 1, 2016, the Company completed a registered direct offering of 2,100,000 units (the "Units"), with each Unit consisting of one common
share or one pre-funded warrant to purchase one common share and 0.45 of a warrant to purchase one common share (the "November 2016 Offering").

Total  gross  cash  proceeds  raised  through  the  November  2016  Offering  amounted  to  $7.6  million,  less  cash  transaction  costs  of  $1.0  million,  and
previously deferred transactions costs of $27,000. The warrants are exercisable six months after their date of issuance and for a period of three years
thereafter at an exercise price of $4.70 per share.

The warrants contain a call provision which provides that, in the event the Company's common shares trade at or above $10 on the market during a
specified measurement period and subject to a minimum volume of trading during such measurement period, then, subject to certain conditions, the
Company has the right to call for cancellation all or any portion of the warrants which are not exercised by holders within 10 trading days following
receipt of a call notice from the Company.

(tabular amounts in thousands of US dollars, except share/option/warrant and per share/option/warrant data and as otherwise noted)

Upon complete exercise for cash, these warrants would result in the issuance of an aggregate of 945,000 common shares that would generate additional
proceeds of approximately $4.4 million, although these warrants may be exercised on a "net" or "cashless" basis. See also note 14 - Warrant liability.

The Company estimated the fair value attributable to the warrants as of the date of grant by applying probability to multiple Black-Scholes pricing
models, to which the following weighed average assumptions were applied: a risk-free annual interest rate of 0.63%, an expected volatility of 112.48%,
an  expected  life  of  1.63  years  and  a  dividend  yield  of  0.0%.  In  addition,  the  Company  reduced  the  fair  value  of  these  warrants  to  take  into
consideration the fair value of the $10.00 call option, which was also calculated using the Black-Scholes pricing model with similar assumptions as
described above. As a result, on November 1, 2016, being the date of issuance, the total fair value of the share purchase warrants was estimated at
$400,000.

The pre-funded warrants were offered in the November 2016 Offering to the investor because the purchase of Units would have resulted in the investor
beneficially  owning  more  than  an  "initial  beneficial  ownership  limitation"  of  4.9%  of  our  common  shares  following  the  offering.  The  pre-funded
warrants, which were exercisable immediately upon issuance and for a period of five years at an exercise price of $3.60 per share, were fully exercised
between November 10, 2016 and December 19, 2016. Total gross proceeds payable to the Company in connection with the exercise of the pre-funded
warrants were pre-funded by the investor and therefore were included in the proceeds of the offering. No additional consideration was required to be
paid to the Company upon exercise of the pre-funded warrants.

Total  gross  proceeds  of  the  November  2016  Offering  were  allocated  as  follows:  $400,000  was  allocated  to  the  warrant  liability,  $3,239,000  was
allocated to the pre-funded warrants, and the balance of $3,921,000 was allocated to Share capital. Transaction costs were allocated to the liability and
equity components in proportion to the allocation of proceeds. As such, an amount of $56,000 was allocated to the warrant liability and immediately
recognized in general and administrative expenses in the consolidated statement of comprehensive loss, an amount of $544,000 was allocated to Share
capital and an amount of $450,000 was allocated to pre-funded warrants. Upon exercise of the pre-funded warrants, the net proceeds initially allocated
to the pre-funded warrants were re-allocated to Share capital.

Shareholder rights plan

The Company has a shareholder rights plan (the "Rights Plan") that provides the Board of Directors and the Company's shareholders with additional
time to assess any unsolicited take-over bid for the Company and, where appropriate, to pursue other alternatives for maximizing shareholder value.
Under the Rights Plan, one right has been issued for each currently issued common share, and one right will be issued with each additional common
share that may be issued from time to time. The Rights Plan was approved, ratified and confirmed by the Company's shareholders at its annual meeting
of shareholders held on May 10, 2016.

Stock options

The Company has in place a stock option plan (the "Stock Option Plan") for its directors, senior executives, employees and other collaborators who
provide services to the Company. The total number of common shares that may be issued under the Stock Option Plan cannot exceed 11.4% of the total
number of issued and outstanding common shares at any given time. The Company's Board of Directors amended the Stock Option Plan on March 20,
2014 and the Company's Shareholders approved, ratified and confirmed the Stock Option Plan on May 10, 2016.

Options granted under the Stock Option Plan prior to the 2014 amendment expire after a maximum period of 10 years following the date of grant.
Options granted after the 2014 amendment expire after a maximum period of seven years following the date of grant.

The following tables summarize the activity under the Stock Option Plan.

18 Employee future benefits

The  Company's  subsidiary  in  Germany  provides  unfunded  defined  benefit  pension  plans  and  unfunded  post-employment  benefit  plans  for  certain
groups  of  employees.  Provisions  for  pension  obligations  are  established  for  benefits  payable  in  the  form  of  retirement,  disability  and  surviving
dependent pensions.

The unfunded defined benefit pension plans are final salary pension plans, which provide benefits to members (or to their surviving dependents) in the
form of a guaranteed level of pension payable for life. The level of benefits provided depends on the member's length of service and on his or her base
salary  in  the  final  years  leading  up  to  retirement.  Current  pensions  vary  in  accordance  with  applicable  statutory  requirements,  which  foresee  an
adjustment  every  three  years  on  an  individual  basis  that  is  based  on  inflationary  increases  or  in  relation  to  salaries  of  comparable  groups  of  active
employees  in  the  Company. An  adjustment  may  be  denied  by  the  Company  if  the  Company's  financial  situation  does  not  allow  for  an  increase  in
pensions. These plans are unfunded, and the Company meets benefit payment obligations as they fall due.

The change in the Company's accrued benefit obligations is summarized as follows:

The calculation of the pension benefit obligation is sensitive to the discount rate assumption. Since January 1, 2017, management determined that the
discount rate assumption should be adjusted from 1.6% to 1.7% as a result of changes in the European economic environment.

Assumptions  regarding  future  mortality  are  set  based  on  actuarial  advice  in  accordance  with  published  statistics  and  experience  in  Germany.  These
assumptions translate into an average remaining life expectancy in years for a pensioner retiring at age 65:

Retiring at the end of the reporting period:

Male

Female

Retiring 20 years after the end of the reporting period:

Male

The most recent actuarial reports give effect to the pension and post-employment benefit obligations as at December 31, 2017. The next actuarial
reports are planned for December 31, 2018.

In accordance with the assumptions used as at December 31, 2017, undiscounted defined pension benefits expected to be paid are as follows:

Total  expenses  for  the  Company's  defined  contribution  plan  in  its  German  subsidiary  amounted  to  approximately  $119,000  for  the  year  ended
December 31, 2017 ($129,000 for 2016 and $159,000 for 2015).

21 Capital disclosures

The Company's objective in managing capital, consisting of shareholders' equity, with cash and cash equivalents and restricted cash equivalents being
its primary components, is to ensure sufficient liquidity to fund R&D costs, selling expenses, G&A expenses and working capital requirements.

Over the past several years, the Company has raised capital via public equity offerings and issuances under various ATM sales programs as its primary
source of liquidity, as discussed in note 16 - Share capital.

funds  available  to  finance  the  activities  required  to  advance  the  Company's  product  development  portfolio  and  to  pursue  appropriate  commercial
opportunities as they may arise.

The Company is not subject to any capital requirements imposed by any regulators or by any other external source.

The Black-Scholes valuation methodology uses "Level 2" inputs in calculating fair value, as defined in IFRS 13, which establishes a hierarchy that
prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical
assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The input levels discussed in IFRS 13
are:

Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 – Inputs other than quoted prices included within Level 1 that are observable for an asset or liability, either directly (i.e. prices) or indirectly

(i.e. derived from prices).

Level 3 – Inputs for an asset or liability that are not based on observable market data (unobservable inputs).

The  carrying  values  of  the  Company's  cash  and  cash  equivalents,  trade  and  other  receivables,  restricted  cash  equivalents,  payables  and  accrued
liabilities, provision for restructuring costs and other non-current liabilities approximate their fair values due to their short-term maturities or to the

Financial risk factors

The following provides disclosures relating to the nature and extent of the Company's exposure to risks arising from financial instruments, including
credit risk, liquidity risk and market risk (share price risk) and how the Company manages those risks.

(a) Credit risk

Credit risk is the risk of an unexpected loss if a customer or counterparty to a financial instrument fails to meet its contractual obligations. The
Company regularly monitors credit risk exposure and takes steps to mitigate the likelihood of this exposure resulting in losses. The Company's
exposure to credit risk currently relates to the loans and receivables in the table above. The Company holds its available cash in amounts that are
readily convertible to known amounts of cash and deposits its cash balances with financial institutions that have an investment grade rating of at
least "P-2" or the equivalent. This information is supplied by independent rating agencies where available and, if not available, the Company
uses publicly available financial information to ensure that it invests its cash in creditworthy and reputable financial institutions.

As  at  December  31,  2017,  trade  accounts  receivable  for  an  amount  of  approximately  $20,000  were  with  three  counterparties,  and  no  trade
accounts receivable were past due and none were impaired.

Generally, the Company does not require collateral or other security from customers for trade accounts receivable; however, credit is extended
following an evaluation of creditworthiness. In addition, the Company performs ongoing credit reviews of all of its customers and establishes an
allowance for doubtful accounts when accounts are determined to be uncollectible.

The maximum exposure to credit risk approximates the amount recognized in the Company's consolidated statement of financial position.

(b) Liquidity risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they become due. As indicated in note 21 - Capital
disclosures,  the  Company  manages  this  risk  through  the  management  of  its  capital  structure.  It  also  manages  liquidity  risk  by  continuously
monitoring actual and projected cash flows. The Board of Directors reviews and approves the Company's operating and capital budgets, as well
as any material transactions occurring outside of the ordinary course of business. The Company has adopted an investment policy in respect of
the  safety  and  preservation  of  its  capital  to  ensure  the  Company's  liquidity  needs  are  met.  The  instruments  are  selected  with  regard  to  the
expected timing of expenditures and prevailing interest rates.

On December 20, 2017, the FDA granted marketing approval for Macrilen™ (macimorelin) to be used in the diagnosis of patients with AGHD.
On  January  16,  2018,  the  Company,  through  AEZS  Germany  entered  into  the  Strongbridge  License  Agreement.  The  Strongbridge  License
Agreement will contribute to fulfilling the Company's future obligations (see note 26 - Subsequent events).

(c) Market risk

Share price risk

The  change  in  fair  value  of  the  Company's  warrant  liability,  which  is  measured  at  FVTPL,  results  from  the  periodic  "mark-to-market"
revaluation,  via  the  application  of  option  pricing  models,  of  currently  outstanding  share  purchase  warrants.  These  valuation  models  are
impacted, among other inputs, by the market price of the Company's common shares. As a result, the change in fair value of the warrant liability,
which is reported in the consolidated statements

of  comprehensive  loss,  has  been  and  may  continue  in  future  periods  to  be  materially  affected  most  notably  by  changes  in  the  Company's

Net loss per share is calculated by dividing net loss by the weighted average number of shares outstanding during the relevant period. Diluted weighted
average number of shares reflects the dilutive effect of equity instruments, such as any "in the money" stock options and share purchase warrants. In
periods with reported net losses, all stock options and share purchase warrants are deemed anti-dilutive such that basic net loss per share and diluted net
loss per share are equal, and thus "in the money" stock options and share purchase warrants have not been included in the computation of net loss per
share because to do so would be anti-dilutive.

25 Commitments and contingencies

The Company is committed to various operating leases for its premises. Expected future minimum lease payments, which also include future payments

In  the  normal  course  of  operations,  the  Company  may  become  involved  in  various  claims  and  legal  proceedings  related  to,  for  example,  contract

Class Action Lawsuit

The Company and certain of its former officers are defendants in a putative class action lawsuit brought on behalf of shareholders of the Company. The
pending  lawsuit  is  the  result  of  the  consolidation  of  several  lawsuits,  the  first  of  which  was  filed  on  November  11,  2014.  The  plaintiffs  filed  their
amended consolidated complaint on April 10, 2015. The amended complaint alleged violations of the Securities Exchange Act of 1934 in connection
with  allegedly  false  and  misleading  statements  made  by  the  defendants  between  August  30,  2011  and  November  6,  2014  (the  "Class  Period"),
regarding the safety and efficacy of Macrilen™ and the prospects for the approval of the Company's new drug application for the product by the FDA.
The  plaintiffs  seek  to  represent  a  class  comprised  of  purchasers  of  the  Company's  common  shares  during  the  Class  Period  and  seek  unspecified
damages, costs and expenses and such other relief as determined by the Court.

On March 2, 2015, the lawsuits were consolidated into one class action, and a Lead Plaintiff and Lead Counsel were appointed. On April 10, 2015,
Lead Plaintiff filed an Amended Complaint. On May 26, 2015, the Company filed a motion to dismiss the class action.

On September 14, 2015, the Court dismissed the lawsuit, but granted the plaintiffs leave to amend. In dismissing the lawsuit, the Court affirmed that
the plaintiffs had failed to state a claim. On October 14, 2015,  the  plaintiffs  filed  a  second  amended  complaint.  The  Company  subsequently  filed  a
motion  to  dismiss  the  second  amended  complaint.  On  March  2,  2016,  the  Court  issued  an  order  granting  the  Company's  motion  to  dismiss  the
complaint in part and denying it in part. The Court dismissed certain of the Company's former officers from the lawsuit. The Court allowed the claim
that the Company misrepresented and omitted material facts from its public statements during the Class Period to proceed against the Company and its
former  CEO,  who  departed  in  2013,  while  dismissing  such  claims  against  other  former  officers.  The  Court  also  allowed  a  claim  for  "controlling
person" liability to proceed against certain former officers.

The Company filed a motion for reconsideration of the Court's March 2, 2016 order on March 16, 2016 and filed an answer to the second amended
complaint on April 6, 2016. On June 30, 2016, the Court issued an order denying the Company's motion for reconsideration. Lead Plaintiffs filed a
motion for class certification on May 8, 2017, on which a hearing was held on July 20, 2017. The court granted the motion for class certification on
February 28, 2018, which we appealed. We filed an interlocutory petition for review on March 14, 2018.  Lead Plaintiff’s opposition to the petition was
due on Monday, March 26, 2018.

(tabular amounts in thousands of US dollars, except share/option/warrant and per share/option/warrant data and as otherwise noted)

The  Company's  directors'  and  officers'  insurance  policies  ("D&O  Insurance")  provide  for  reimbursement  of  certain  costs  and  expenses  incurred  in
connection with the defense of this lawsuit, including legal and professional fees, as well as other loss (damages, settlements, and judgments), if any,
subject  to  certain  policy  exclusions,  restrictions,  limits,  deductibles  and  other  terms.  The  Company  believes  that  the  D&O  Insurance  applies  to  the
purported class-action lawsuit; however, the insurers have issued standard reservations of rights letters reserving all rights under the D&O Insurance.
Legal  and  professional  fees  are  expensed  as  incurred,  and  no  reserve  is  established  for  them.  During  the  second  quarter  of  2016,  the  Company
exceeded  the  deductible  amount  applicable  to  this  claim.  Therefore,  the  Company  believes  that  the  insurers  will  bear  most  of  the  costs  for  the
Company's defense in future periods, subject to the Company's policy limits.

While the Company believes that it has meritorious defenses and intends to defend this lawsuit vigorously, management cannot currently predict the
outcome of this suit or reasonably estimate any potential loss that may result from this suit. Accordingly, the Company has not recorded any liability
related to the lawsuit. No assurance can be given with respect to the ultimate outcome of such proceedings, and the Company could incur substantial
unreimbursed legal fees, damages, settlements, judgments, and other expenses in connection with these proceedings that may not qualify for coverage
under,  or  may  exceed  the  limits  of,  its  applicable  D&O  Insurance  and  could  have  a  material  adverse  impact  on  the  Company's  financial  condition,
results of operations, liquidity and cash flows.

Other lawsuits

In  late  July  2017,  the  Company  terminated  for  cause  the  employment  agreement  of  Mr.  David  A.  Dodd,  the  former  President  and  Chief  Executive
Officer  and  it  also  terminated  the  employment  of  Mr.  Philip  A.  Theodore,  the  former  Senior  Vice  President,  Chief  Administrative  Officer,  General
Counsel and Corporate Secretary. All outstanding stock options held by both former officers were cancelled effective as of their respective termination
dates, in accordance with the provisions of the Company's Stock Option Plan.

On August 3, 2017, the Company announced that it had filed a lawsuit against both Messrs. Dodd and Theodore for damages suffered by the Company
for  breach  of  confidence  and/or  breach  of  fiduciary  duty  in  an  amount  to  be  determined  prior  to  trial.  The  Company  is  also  seeking,  among  other
things, an injunction to prevent both Messrs. Dodd and Theodore (i) from continuing to use the Company's confidential and proprietary information
without authorization and (ii) from mounting a proxy contest that will be premised upon the breaches of fiduciary and statutory duties and breaches of
confidence  alleged  in  the  lawsuit.  The  Company  engaged  external  counsel  to  conduct  an  internal  investigation  related  to  this  lawsuit,  which  is  still
ongoing. 

On  December  21,  2017,  Messrs.  Dodd  and  Theodore  brought  a  counterclaim  against  the  Company  and  its  Chair,  Carolyn  Egbert,  in  the  amount  of
CAN$6.0  million  alleging,  among  other  things,  that  defamatory  statements  were  made  against  Messrs.  Dodd  and  Theodore.  The  Company  and  its
Chair consider the counterclaim against them to be entirely without merit, and intend to vigorously defend against the counterclaim.

In August 2017, Mr. Dodd filed a lawsuit in the Court of Common Pleas of South Carolina against the Company for damages of approximately $1.7
million. He is also requesting that all of his outstanding stock options vest effective upon his termination date. The Company cannot predict at this time
the final outcome or potential losses, if any, with respect to this lawsuit.

Cogas Consulting, LLC ("Cogas") filed a lawsuit against the Company in state court in Fulton County, Georgia on February 2, 2018. Cogas alleges that
its employee (and sole shareholder) John Sharkey is entitled to a "success fee" commission on the Strongbridge License Agreement. Cogas is claiming
damages in the form of a lost commission on the transaction. Cogas claims its commission is 5% on payments the Company receives within the first
three years after January 14, 2018. Cogas alleges it is entitled to 5% of the $24 million Strongbridge already paid the Company, plus 5% of any royalty
Strongbridge pays the Company through January 17, 2021. The Company plans to vigorously defend this matter.

26 Subsequent events

On January 16, 2018, the Company through AEZS Germany entered into the Strongbridge License Agreement. The Company received an upfront cash
payment of $24,000,000 from Strongbridge, and, for as long as Macrilen™ (macimorelin) is patent-protected, the Company will be entitled to a 15%
royalty on net sales up to $75,000,000 and an 18% royalty on net sales above $75,000,000. Following the end of patent protection in United States or
Canada for Macrilen™ (macimorelin), the Company will be entitled to a 5% royalty on net sales in that country. In addition, the Company will also
receive one-time payments from Strongbridge following the first achievement of the following commercial milestone events:

• $4,000,000 on achieving $25,000,000 annual net sales,

• $10,000,000 on achieving $50,000,000 annual net sales,

• $20,000,000 on achieving $100,000,000 annual net sales,

• $40,000,000 on achieving $200,000,000 annual net sales, and

• $100,000,000 on achieving $500,000,000 annual net sales.

Upon  approval  by  the  FDA  of  a  pediatric  indication  for  Macrilen™  (macimorelin),  the  Company  will  receive  a  one-time  milestone  payment  of
$5,000,000 from Strongbridge.

Strongbridge will fund 70% of the costs of a worldwide pediatric development program to be run by the Company with customary oversight from a
joint steering committee. The joint steering committee will be comprised of four persons, two of whom will be appointed by each of Strongbridge and
the Company.

reviewed annually by the Board or a committee of the Board and may be increased in accordance with the Corporation’s
compensation  policy.  The  Corporation  shall  increase  the  Base  Salary  to  Three  Hundred  and  Twenty  Five  Thousand  US
(US$325,000.00)  upon  approval  of  Macrilen  by  the  U.S.  Food  and  Drug  Administration.  Finally,  all  or  part  of  the
Executive’s Base Salary may be paid through an Affiliate of the Corporation.

Annual Cash Bonus. The Executive shall be eligible to earn an annual cash bonus (the Annual Bonus). The granting of an
Annual  Bonus,  if  any,  shall  be  based  on  both  the  performance  of  the  business  and  the  Executive  and  it  is  subject  to  the
approval by the Board in its sole discretion. The amount of the Annual Bonus shall be calculated based upon the formula of
the Annual Bonus plan for executives, which currently ranges in target from 0 to 65%. The Annual Bonus, if any, payable
for  any  calendar  year  shall  be  paid  no  later  than  March  15  of  the  following  calendar  year.  To  be  eligible  to  receive  any
Annual Bonus, the Executive must be a current employee in good standing of the Corporation at the time that Annual Bonus
payments are made.

Stock Options. Subject  to  any  required  shareholder  or  regulatory  approval,  the  Executive  shall  be  eligible  to  receive  an
annual  grant  of  stock  options  to  purchase  shares  of  the  Corporation’s  publically-traded  common  stock  (the  “Common
Stock”),  subject  to  vesting,  exercise,  pricing  and  all  other  applicable,  terms  of  the  Corporation’s  Stock  Option  Plan.
Granting of such annual stock options shall also be subject to the prior approval and the sole discretion of the Board. If any
shareholder  or  regulatory  approval  is  required,  the  Corporation  shall  promptly  undertake  all  reasonable  efforts  to  secure
such approval.

3.4

Subject to eligibility requirements and participation rules, the Executive may participate in all of the employee benefit plans

SECTION 6 -TERMINATION:

6.1

6.2

At-Will Employment. Nothing in this Agreement shall be construed to alter the at-will employment relationship between
the Corporation and the Executive. Subject to the terms set forth in this Agreement, either the Corporation or the Executive
may terminate Executive’s employment at any time for any reason, with or without Cause, as defined in Section 6.3 below.

Termination for Cause. The Executive’s employment may be terminated by the Corporation upon simple notice in writing
transmitted  to  the  Executive,  without  the  Corporation  (or  any  of  its  Affiliates)  being  bound  to  pay  any  compensation
whatsoever if termination is for any of the following reasons, each of which constitutes Cause:

(a)

(b)

(c)

(d)

The  Executive  is  declared  bankrupt  or  insolvent  or  makes  an  assignment  of  substantially  all  of  his  property  or  is
placed under protective supervision.

The Executive becomes physically or mentally disabled to such an extent as to render him unable to perform the
essential functions of his job duties normally and adequately for an aggregate of twelve (12) weeks during a period
of twelve (12) consecutive months. In such a case, the Executive may continue to benefit under short-term and long-
term disability insurance plans, subject to the terms of such plans, if any. The Corporation’s ability to terminate the
Executive as a result of any disability shall be to the extent permitted by applicable state or federal law.

The  Executive  materially  fails  or  refuses  to  adequately  perform  the  duties  or  responsibilities  assigned  by  the
Corporation or its Board.

The Executive engages in fraud, theft, embezzlement or other criminal act of a similar nature, or commits an act of
serious misconduct or willful or gross negligence in the performance of his duties.

(e)The Executive fails or refuses to follow reasonable directives of the Board.

(f)

The  Executive  conducts  himself,  by  speech  or  behavior,  in  such  a  manner  as  to  cause  embarrassment,  scandal  or
ridicule  to  the  Corporation,  any  of  its  affiliates  or  any  of  their  employees  or  to  create,  foment  or  engender  a
disrespectful, divisive or hostile workplace environment.

(g)The Executive misuses or abuses alcohol, drugs or controlled substances.

(h)The Executive materially breaches Sections 7, 8 or 9 of this Agreement.

(i)

Provided, however, that the reason set forth in subsection 6.2(c) shall not constitute Cause unless the Executive is
given a reasonable period (at least 10 days) to effect a cure or a correction and fails to do so (and provided that the
reason  is  curable  or  correctible  as  determined  in  the  reasonable  discretion  of  the  Board).  Furthermore,  whether  a
Cause event has occurred shall be determined in the reasonable discretion of the Board.

6.1

Good Reason. The Executive shall have the right to resign at any time for any of the following reasons, each of which shall
constitute Good Reason:

6.2

6.3

6.4

(a)A  material  reduction  of  the  Executive’s  Base  Salary  as  in  effect  on  the  Effective  Date  or  as  thereafter  increased  from
time to time, provided such reduction is not applicable in a similar manner to the other senior executives of the Corporation.

(b)A material and sustained reduction (absent the Executive’s express, written consent) in the Executive’s overall duties and
responsibilities as the President and Chief Executive Officer.

(c)Provided,  however,  no  reason  set  forth  in  this  Section  6.3  shall  constitute  Good  Reason  unless  1)  the  Executive  first
gives written notice to the Board of the facts that constitute Good Reason; 2) the Corporation fails to cure or correct the
situation within 10 days following receipt of such notice (the “cure period”); and 3) the Executive resigns his employment
within 30 days following the end of the cure period.

Termination by Death. In the event of the Executive’s death during his period of employment, the Corporation’s obligation
to  make  payments  under  this  Agreement  shall  terminate  on  the  date  of  death,  except  the  Corporation  shall  pay  the
Executive’s  estate  or  surviving  designated  beneficiary  or  beneficiaries,  as  appropriate,  any  earned  but  unpaid  salary  and
bonus and reimburse business expenses incurred but not reimbursed as of his date of death. Vesting of any stock options
outstanding on the date of death shall be exercisable only to the extent the Executive’s right to exercise was vested on his
date of death.

Voluntary Termination. If the event Executive wishes to resign for any reason other than Good Reason or the Corporation
wishes to terminate his employment without Cause, the Executive shall give, or receive, as applicable at least thirty (30)
days prior written notice of such resignation or termination, whichever is applicable. Any such notice shall not relieve either
the Executive or the Corporation of their mutual obligations to perform under this Agreement or to relieve the Corporation
to compensate the Executive during such notice period for any earned but unpaid salary and bonus and reimburse business
expenses incurred but not reimbursed as of his date of termination.

Termination Without Cause Or Resignation For Good Reason. In the event that the Executive has a “separation from
service”  within  the  meaning  of  a  §409A  of  the  US  Internal  Revenue  Code  of  1986,  as  amended  (a  “Separation  from
Service”) as a result of the Corporation terminating the Executive’s employment without Cause or the Executive resigning
for Good Reason, except for a termination under Section 6.2, the Corporation shall pay to Executive an amount equal to at
least 18 months of his then Base Salary (the “Severance Pay”). [The Severance Pay shall not be prorated for partial years of
service]. The Severance Pay shall be paid out in equal installments in accordance with the Corporation’s standard payroll
cycle (less applicable tax withholdings) over a period of one year, commencing with the first regular payroll date that is at
least seven days after the Corporation receives the Release referenced below from Executive, and assuming Executive does
not  revoke  the  release.  The  right  to  payment  of  the  Severance  Pay  is  conditioned  upon  Executive’s  executing,  and  not
revoking,  a  full  and  general  Release  of  all  claims  in  a  form  satisfactory  to  the  Corporation  and  full  compliance  with  the
terms  of  this  Agreement.  If  necessary,  all  payments  due  under  this  Section  6.7  by  the  Corporation  may  be  delayed  as
required  by  §409A  of  the  US  Internal  Revenue  Code  of  1986  (the  “Code”);  the  payments  shall  be  so  delayed  by  six  (6)
months  and  one  day,  and  the  first  six  (6)  months’  Severance  Pay  shall  be  paid  in  a  lump  sum  on  the  first  payroll  date
thereafter. The Corporation has the right to cease making payments under this paragraph at any time it determines Executive
is in breach of Sections 7,8, or 9 of this Agreement.

6.5

Clawback of any Erroneously Paid Compensation. If, after a payment is made to the Executive pursuant to Section 3, 4,
5 or 6, the Corporation finds, after full consideration of the facts, that the Executive engaged in fraud, theft, embezzlement
or  any  other  criminal  act  of  a  similar  nature  in  the  performance  of  his  duties  to  the  Corporation,  the  Executive  must
immediately repay to the Corporation all amounts that were paid to him pursuant to Section 3, 4, 5 or 6 of the Agreement.

SECTION 7 -NO-COMPETITION, NO SOLICITATION AND LOYALTY:

7.1

During the duration of the Executive’s employment and for a period of one (1) year following the date of termination of his
employment,  Executive  shall  not  compete  with  the  Corporation,  directly  or  indirectly,  in  the  development  and
commercialization of the same or substantially similar endocrine therapies and oncology treatments that the Corporation is
developing,  including,  without  limitation,  as  an  executive,  director,  officer,  employer,  principal,  agent,  fiduciary,
administrator of another’s property, associate, independent contractor, franchisor, franchisee, distributor or consultant of or
for a competing entity, unless such participation is fully disclosed to the Board and approved in writing in advance by the
Chairman of the Board. In addition, the Executive shall not have any interest whatsoever in such an enterprise, including,
without limitation, as owner, shareholder, partner, limited partner, lender or silent partner. This non-competition covenant is
limited  in  geographic  scope  to  those  geographic  areas  in  the  United  States,  Canada  and  Europe  in  which  the  same  or
substantially similar endocrine therapies and oncology treatments are developed and commercialized by the Corporation or

its Affiliates. The term of the non-competition covenant shall be tolled during any period in which Executive has violated
the covenant for any reason.

The  foregoing  stipulation  shall  nevertheless  not  prevent  the  Executive  from  purely  passive  investments  in  the  shares  or
other securities of a corporation or entity other than the Corporation whose securities are publicly traded on a recognized
stock exchange where the securities so held by the Executive do not represent more than five percent (5%) of the voting
shares of such other corporation or entity and do not allow for its control.

The Executive also undertakes, for the same period and in respect of the same territory referred to hereinabove in Section
7.1  not  to  solicit  clients  of  the  Corporation  or  its  Affiliates  with  which  he  had  any  contact  during  the  period  of  his
employment with the Corporation, or do anything whatsoever to induce or to lead any person to end, in whole or in part,
business relations with the Corporation or any of its affiliates.

The Executive also undertakes, for the same period and in respect of the same territory referred to hereinabove in Section
7.1 not to interfere in the relations which the Corporation or which any of its affiliates has with their distributors, suppliers,
representatives,  agents  and  other  parties  with  whom  the  Corporation  or  any  of  its  affiliates  deals,  including  inducing  or
attempting to induce such entities to cease doing business with the Corporation or its affiliates.

The  Executive  also  undertakes,  for  the  same  period  and  in  respect  of  the  same  territory  referred  to  in  Section  7.1  not  to
induce,  attempt  to  induce  or  otherwise  solicit  the  personnel  of  the  Corporation  to  leave  their  employment  with  the
Corporation or any of its affiliates nor to hire the personnel of the Corporation or any of its affiliates for any enterprise in
which the Executive has an interest.

The  Executive  acknowledges  that  the  provisions  of  this  Section  7  are  reasonably  limited  as  to  the  time  period,  the
geographic area and the nature of the activities to what the parties deem necessary to protect the legitimate interests of the
Corporation and its affiliates, while allowing the Executive to earn his living.

Nothing in this Section 7 shall operate to reduce or extinguish the obligations of the Executive arising at law or under this
contract which survive at the termination of this Agreement in reason of their nature and, in particular, without limiting the
foregoing, the Executive’s duty of loyalty and obligation to act faithfully, honestly and ethically.

during  his  employment  with  the  Corporation,  confidential  information  pertaining  to  the  activities,  the  technologies,  the
operations and the business, past, present and future, of the Corporation, which information is not in the public domain. The
Executive  acknowledges  that  such  confidential  information  belongs  to  the  Corporation  and  that  its  disclosure  or
unauthorized use could be damaging or prejudicial to the Corporation and contrary to their best interests.

Accordingly, the Executive agrees to respect the confidentiality of such information and not to make use of or disclose it to,
or to discuss it with, any person, other than in the ordinary course of his duties with the Corporation, or as required under
applicable law, without the explicit prior written authorization of the Corporation.

This undertaking to respect the confidentiality of such information and not to make use of or disclose or discuss it to or with
any  person  shall  survive  and  continue  to  have  full  effect  notwithstanding  the  termination  of  the  Executive’s  employment
with  the  Corporation,  so  long  as  such  confidential  information  does  not  become  public  as  a  result  of  an  act  by  the
Corporation or a third party, which act does not involve the fault of one of its Executives.

8.2

The term confidential information includes, among other things:

8.2.1 products,  formulae,  processes  and  composition  of  products,  as  well  as  raw  materials  and  ingredients,  of  whatever

The  Executive  agrees  to  keep  confidential  and  not  disclose  to  any  third  party  both  the  existence  and  the  terms  of  this
Agreement, except if disclosure is required by regulation or law. In the event Executive is required to disclose the existence
or terms of this Agreement pursuant to subpoena or other duly issued court order, Executive shall give prompt notice to the
Corporation  of  such  subpoena  or  court  order  to  allow  the  Corporation  sufficient  opportunity  to  contest  such  subpoena  or
court order.

Nothing  in  this  Section  8  shall  be  read  to  prevent  Executive  from  discussing  or  disclosing  confidential  information  in
connection with an investigation by the SEC, the EEOC, the NLRB or another state or federal agency, or from filing and/or
pursuing a charge or complaint with any such agency.

modify or reproduce any such document or work realized by the Executive, at its entire discretion, without the Executive’s
authorization and without his name being mentioned.

At  any  time  during  the  period  of  his  employment  or  after  the  termination  of  his  employment,  the  Executive  shall  sign,
acknowledge and deliver, at the Corporation’s expense, but without compensation other than a reasonable sum for his time
devoted thereto if his employment has then terminated, any document required by the Corporation to give effect to Section
9.1, including patent applications and documents evidencing the assignment of ownership. The Executive shall also provide
such  other  assistance  as  the  Corporation  or  one  of  its  affiliates  may  require  with  respect  to  any  proceeding  or  litigation
relating to the protection or defense of intellectual property rights belonging to the Corporation or any of its affiliates.

conveyance,  transfer,  assignment,  mortgage,  pledge,  or  encumbrance  of  the  benefits  hereunder  prior  to  payment  thereof  shall  be

agreement of the parties. The Corporation shall bear all fees and expenses of the mediator. The parties shall bear the expense of
their  own  attorneys’  fees.  If  the  mediation  fails  to  result  in  a  prompt  settlement,  the  arbitration  shall  be  conducted  in  Dover,
Delaware  by  one  arbitrator  who  is  designated  in  accordance  with  the  then  current  employment  rules  and  procedures  of  the

Term of this Agreement, the Executive is not required to seek other employment or to attempt in any way to reduce any amounts
payable to the Executive by the Corporation pursuant to this Agreement. Further, except as expressly provided otherwise herein, the
amount  of  any  payment  or  benefit  provided  for  in  this  Agreement  shall  not  be  reduced  by  any  compensation  earned  by  the
Executive  as  the  result  of  employment  by  another  employer,  by  retirement  benefits,  by  offset  against  any  amount  claimed  to  be
owed by the Executive to the Corporation, or otherwise.

Employment shall be payable or otherwise provided in accordance with such plan, program, contract or policy, except as expressly
modified herein.

to  make  payments  under  this  Agreement  shall  terminate  on  the  date  of  death,  except  the  Corporation  shall  pay  the
Executive’s  estate  or  surviving  designated  beneficiary  or  beneficiaries,  as  appropriate,  any  earned  but  unpaid  salary  and

6.6

6.7

bonus and reimburse business expenses incurred but not reimbursed as of his date of death. Vesting of any stock options
outstanding on the date of death shall be exercisable only to the extent the Executive’s right to exercise was vested on his
date of death.

Voluntary Termination. If the event Executive wishes to resign for any reason other than Good Reason or the Corporation
wishes to terminate his employment without Cause, the Executive shall give, or receive, as applicable at least thirty (30)
days prior written notice of such resignation or termination, whichever is applicable. Any such notice shall not relieve either
the Executive or the Corporation of their mutual obligations to perform under this Agreement or to relieve the Corporation
to compensate the Executive during such notice period for any earned but unpaid salary and bonus and reimburse business
expenses incurred but not reimbursed as of his date of termination.

Termination Without Cause Or Resignation For Good Reason. In the event that the Executive has a “separation from
service”  within  the  meaning  of  a  §409A  of  the  US  Internal  Revenue  Code  of  1986,  as  amended  (a  “Separation  from
Service”) as a result of the Corporation terminating the Executive’s employment without Cause or the Executive resigning
for Good Reason, except for a termination under Section 6.2, the Corporation shall pay to Executive an amount equal to at
least 6 months of his then Base Salary (the “Severance Pay”). This amount shall be increased by one month of base salary
for each full year of service, starting with Executive’s completion of two full years of service and stopping at a maximum of
12  months  of  Base  Salary  after  seven  full  years  of  service.  The  Severance  Pay  shall  not  be  prorated  for  partial  years  of
service. The  Severance  Pay  shall  be  paid  out  in  equal  installments  in  accordance  with  the  Corporation’s  standard  payroll
cycle (less applicable tax withholdings) over a period of one year, commencing with the first regular payroll date that is at
least seven days after the Corporation receives the Release referenced below from Executive, and assuming Executive does
not  revoke  the  release.  The  right  to  payment  of  the  Severance  Pay  is  conditioned  upon  Executive’s  executing,  and  not
revoking,  a  full  and  general  Release  of  all  claims  in  a  form  satisfactory  to  the  Corporation  and  full  compliance  with  the
terms  of  this  Agreement.  If  necessary,  all  payments  due  under  this  Section  6.7  by  the  Corporation  may  be  delayed  as
required  by  §409A  of  the  US  Internal  Revenue  Code  of  1986  (the  “Code”);  the  payments  shall  be  so  delayed  by  six  (6)
months  and  one  day,  and  the  first  six  (6)  months’  Severance  Pay  shall  be  paid  in  a  lump  sum  on  the  first  payroll  date
thereafter. The Corporation has the right to cease making payments under this paragraph at any time it determines Executive
is in breach of Sections 7, 8, or 9 of this Agreement.

6.8

Clawback of any Erroneously Paid Compensation. If, after a payment is made to the Executive pursuant to Section 3, 4,
5 or 6, the Corporation finds, after full consideration of the facts, that the Executive engaged in fraud, theft, embezzlement
or  any  other  criminal  act  of  a  similar  nature  in  the  performance  of  his  duties  to  the  Corporation,  the  Executive  must
immediately repay to the Corporation all amounts that were paid to him pursuant to Section 3, 4, 5 or 6 of the Agreement.

SECTION 7 -    NO-COMPETITION, NO SOLICITATION AND LOYALTY:

7.1

7.2

7.3

7.4

During the duration of the Executive’s employment and for a period of one (1) year following the date of termination of his
employment,  Executive  shall  not  compete  with  the  Corporation,  directly  or  indirectly,  in  the  development  and
commercialization of the same or substantially similar endocrine therapies and oncology treatments that the Corporation is
developing,  including,  without  limitation,  as  an  executive,  director,  officer,  employer,  principal,  agent,  fiduciary,
administrator of another’s property, associate, independent contractor, franchisor, franchisee, distributor or consultant of or
for a competing entity, unless such participation is fully disclosed to the Board and approved in writing in advance by the
Chairman of the Board. In addition, the Executive shall not have any interest whatsoever in such an enterprise, including,
without limitation, as owner, shareholder, partner, limited partner, lender or silent partner. This non‑competition covenant is
limited  in  geographic  scope  to  those  geographic  areas  in  the  United  States,  Canada  and  Europe  in  which  the  same  or
substantially similar endocrine therapies and oncology treatments are developed and commercialized by the Corporation or
its Affiliates. The term of the non-competition covenant shall be tolled during any period in which Executive has violated
the covenant for any reason.

The  foregoing  stipulation  shall  nevertheless  not  prevent  the  Executive  from  purely  passive  investments  in  the  shares  or
other securities of a corporation or entity other than the Corporation whose securities are publicly traded on a recognized
stock exchange where the securities so held by the Executive do not represent more than five percent (5%) of the voting
shares of such other corporation or entity and do not allow for its control.

The Executive also undertakes, for the same period and in respect of the same territory referred to hereinabove in Section
7.1  not  to  solicit  clients  of  the  Corporation  or  its  Affiliates  with  which  he  had  any  contact  during  the  period  of  his
employment with the Corporation, or do anything whatsoever to induce or to lead any person to end, in whole or in part,
business relations with the Corporation or any of its affiliates.

The Executive also undertakes, for the same period and in respect of the same territory referred to hereinabove in Section
7.1 not to interfere in the relations which the Corporation or which any of its affiliates has with their distributors, suppliers,
representatives,  agents  and  other  parties  with  whom  the  Corporation  or  any  of  its  affiliates  deals,  including  inducing  or
attempting to induce such entities to cease doing business with the Corporation or its affiliates.

7.5

The  Executive  also  undertakes,  for  the  same  period  and  in  respect  of  the  same  territory  referred  to  in  Section  7.1  not  to

induce,  attempt  to  induce  or  otherwise  solicit  the  personnel  of  the  Corporation  to  leave  their  employment  with  the
Corporation or any of its affiliates nor to hire the personnel of the Corporation or any of its affiliates for any enterprise in
which the Executive has an interest.

The  Executive  acknowledges  that  the  provisions  of  this  Section  7  are  reasonably  limited  as  to  the  time  period,  the
geographic area and the nature of the activities to what the parties deem necessary to protect the legitimate interests of the
Corporation and its affiliates, while allowing the Executive to earn his living.

Nothing in this Section 7 shall operate to reduce or extinguish the obligations of the Executive arising at law or under this
contract which survive at the termination of this Agreement in reason of their nature and, in particular, without limiting the
foregoing, the Executive’s duty of loyalty and obligation to act faithfully, honestly and ethically.

7.6

7.7

Executive  acknowledges  that  such  confidential  information  belongs  to  the  Corporation  and  that  its  disclosure  or
unauthorized use could be damaging or prejudicial to the Corporation and contrary to their best interests.

Accordingly, the Executive agrees to respect the confidentiality of such information and not to make use of or disclose it to,
or to discuss it with, any person, other than in the ordinary course of his duties with the Corporation, or as required under
applicable law, without the explicit prior written authorization of the Corporation.

This undertaking to respect the confidentiality of such information and not to make use of or disclose or discuss it to or with
any  person  shall  survive  and  continue  to  have  full  effect  notwithstanding  the  termination  of  the  Executive’s  employment
with  the  Corporation,  so  long  as  such  confidential  information  does  not  become  public  as  a  result  of  an  act  by  the
Corporation or a third party, which act does not involve the fault of one of its Executives.

8.2

The term confidential information includes, among other things:

The  Executive  agrees  to  keep  confidential  and  not  disclose  to  any  third  party  both  the  existence  and  the  terms  of  this
Agreement, except if disclosure is required by regulation or law. In the event Executive is required to disclose the existence
or terms of this Agreement pursuant to subpoena or other duly issued court order, Executive shall give prompt notice to the
Corporation  of  such  subpoena  or  court  order  to  allow  the  Corporation  sufficient  opportunity  to  contest  such  subpoena  or
court order.

8.4        Nothing  in  this  Section  8  shall  be  read  to  prevent  Executive  from  discussing  or  disclosing  confidential  information  in
connection  with  an  investigation  by  the  SEC,  the  EEOC,  the  NLRB  or  another  state  or  federal  agency,  or  from  filing  and/or
pursuing a charge or complaint with any such agency.

related  to  his  employment  by  the  Corporation.  The  Executive  acknowledges  that  the  Corporation  has  the  right  to  use,
modify or reproduce any such document or work realized by the Executive, at its entire discretion, without the Executive’s
authorization and without his name being mentioned.

At  any  time  during  the  period  of  his  employment  or  after  the  termination  of  his  employment,  the  Executive  shall  sign,
acknowledge and deliver, at the Corporation’s expense, but without compensation other than a reasonable sum for his time
devoted thereto if his employment has then terminated, any document required by the Corporation to give effect to Section
9.1, including patent applications and documents evidencing the assignment of ownership. The Executive shall also provide
such  other  assistance  as  the  Corporation  or  one  of  its  affiliates  may  require  with  respect  to  any  proceeding  or  litigation
relating to the protection or defense of intellectual property rights belonging to the Corporation or any of its affiliates.

conditioned  upon  Executive’s  executing,  and  not  revoking,  a  full  and  general  Release  of  all  claims  in  a  form  satisfactory  to  the
Corporation  and  full  compliance  with  the  terms  of  Executive’s  Employment  Agreement.  If  necessary,  all  payments  due  under
Section 3(a) of this Agreement by the Corporation may be delayed as required by § 409A of the US Internal Revenue Code of 1986
(the “Code”); the payments shall be so delayed by six (6) months and one day, and the first six (6) months’ payments shall be paid
in a lump sum on the first payroll date thereafter.

4

The Corporation has the right to cease making payments under this paragraph at any time it determines Executive is in breach of
Sections 7, 8, or 9 of Executive’s Employment Agreement.

5.    Termination Procedures.

5.1    Notice of Termination. After a Change of Control and during the Term of this Agreement, any purported termination
of  the  Executive’s  employment  shall  be  communicated  by  a  written  Notice  of  Termination  to  the  Executive  or  Corporation  in
accordance with Section 10.8. For purposes of this Agreement, a “Notice of Termination” shall mean a notice which shall indicate
the specific termination provision in this Agreement relied upon and shall set forth in reasonable detail the facts and circumstances
claimed to provide a basis for termination of the Executive’s employment under the provision so indicated.

5.2        Employment Termination Date. “Employment  Termination  Date,”  with  respect  to  any  purported  termination  of  the
Executive’s employment  after  a  Change  of  Control  and  during  the  Term  of  this Agreement, shall mean the date specified in the
Notice of Termination.

6.    Withholding. The Corporation may withhold from any benefits paid under this Agreement all income, employment, and

other taxes required to be withheld under applicable law.

7.    Death of the Executive. If the Executive dies after his Employment Termination Date but before the Executive receives
full payment of the benefits to which he is entitled, any unpaid benefits will be paid to the Executive’s surviving spouse, or if the
Executive does not have a surviving spouse, to the Executive’s estate.

8.       Amendment. This Agreement may not be amended except pursuant to a written instrument that is authorized by the

Corporation and agreed to in writing and signed by the Executive.

9.    Funding. The Executive shall have no right, title, or interest whatsoever in or to any assets of the Corporation or any
investments which the Corporation may make to aid it in meeting its obligations under this Agreement. The Executive’s right to
receive payments under this Agreement shall be no greater than the right of an unsecured general creditor of the Corporation.

10.    Miscellaneous.

10.1    Agreement Not an Employment Contract. This Agreement is not an employment contract between the Corporation
and Executive and gives Executive no right to retain his employment. This Agreement is not intended to interfere with the rights of
the  Corporation  to  terminate  the  Executive’s  employment  at  any  time  with  or  without  notice  and  with  or  without  cause  or  to
interfere with the Executive’s right to terminate his employment at any time.

10.2        Alienation  Prohibited.  No  benefits  hereunder  shall  be  subject  to  anticipation  or  assignment  by  the  Executive,  to
attachment by, interference with, or control of any creditor of the Executive, or to being taken or reached by any legal or equitable
process  in  satisfaction  of  any  debt  or  liability  of  the  Executive  prior  to  its  actual  receipt  by  the  Executive.  Any  attempted
conveyance,

5

transfer, assignment, mortgage, pledge, or encumbrance of the benefits hereunder prior to payment thereof shall be void.

10.3        Severability.  Each  provision  of  this  Agreement  may  be  severed.  If  any  provision  is  determined  to  be  invalid  or

unenforceable, that determination shall not affect the validity or enforceability of any other provision.

10.4    Binding Effect. This Agreement shall be binding upon any successor of the Corporation.

10.5        Mediation  and  Arbitration.    The  Corporation  and  the  Executive  hereby  expressly  agree  that  with  respect  to  any
dispute arising under this Agreement, such dispute shall be addressed first through confidential mediation, and if that fails, through
confidential and binding arbitration. Any such mediation shall take place in Charleston, South Carolina before a single mediator
selected by the agreement of the parties. The Corporation shall bear all fees and expenses of the mediator. The parties shall bear the
expense of their own attorneys’ fees. If the mediation fails to result in a prompt settlement, the arbitration shall be conducted in
Charleston,  South  Carolina  by  one  arbitrator  who  is  designated  in  accordance  with  the  then  current  employment  rules  and
procedures of the American Arbitration Association. The arbitrator shall prepare and publish a reasoned award. Each of the parties
hereto shall bear their own, respective, costs of such arbitration.

10.6    No Mitigation. The Corporation agrees that if the Executive’s employment with the Corporation terminates during the
Term of this Agreement, the Executive is not required to seek other employment or to attempt in any way to reduce any amounts
payable to the Executive by the Corporation pursuant to this Agreement. Further, except as expressly provided otherwise herein, the
amount  of  any  payment  or  benefit  provided  for  in  this  Agreement  shall  not  be  reduced  by  any  compensation  earned  by  the
Executive  as  the  result  of  employment  by  another  employer,  by  retirement  benefits,  by  offset  against  any  amount  claimed  to  be
owed by the Executive to the Corporation, or otherwise.

10.7    Other Amounts Due. Except as expressly provided otherwise herein, the payments and benefits provided for in this
Agreement are in addition to and not in lieu of amounts and benefits that are earned by the Executive prior to his Termination of
Employment. The Executive shall be entitled to any other amounts or benefits due the Executive in accordance with any contract,
plan, program or policy of the Corporation or any of its Affiliates. Amounts that the Executive is entitled to receive under any plan,
program,  contract  or  policy  of  the  Corporation  or  any  of  its  Affiliates  at  or  subsequent  to  the  Executive’s  Termination  of
Employment shall be payable or otherwise provided in accordance with such plan, program, contract or policy, except as expressly
modified herein.

10.8        Notices.  Any  notice  given  hereunder  shall  be  given  in  writing  and  sent  by  registered  or  certified  mail  or  hand-
delivered.  If  such  notice  is  sent  by  registered  or  certified  mail,  it  shall  be  deemed  to  have  been  received  five  (5)  business  days
following  the  date  of  its  mailing  if  the  postal  services  are  working  normally.  If  such  is  not  the  case,  the  notice  must  be  hand-
delivered or served by bailiff, at the discretion of the sender. In the case of hand-delivery or service, the notice shall be deemed to
have been received the same day. It is agreed that if the delivery date is a non-business day, the notice shall be deemed to have been
received on the following business day.

6

For purposes of mailed or hand-delivered notices to be effectively delivered under this provision, the notices must be addressed as
follows:

For the Corporation, the address is: 315 Sigma Drive, Suite 302-D, Summerville. South Carolina 29483.

For the Executive, the address is: 50 Biscayne Blvd., Apt. 4210, Miami, Florida 33132.

10.9        Governing  Law.  This  Agreement  shall  be  governed  by  and  interpreted  in  accordance  with  the  laws,  including
conflicts of laws, by the State of Delaware in the United States of America. Subject to Section 10.5, any lawsuit that arises from or
relates to this Agreement shall be brought exclusively in Dover, Delaware.

10.10    Compliance With Section 409A. It is intended that this Agreement shall comply with Section 409A. The provisions

however, that if a Person shall become the Beneficial Owner of fifty percent (50%) or more of the outstanding Voting Shares by
reason of one or any combination of a Voting Share Reduction, an Exempt Acquisition or a Pro Rata Acquisition, and thereafter
becomes the Beneficial Owner of an additional one percent (1%) of any Voting Share then outstanding (otherwise than pursuant to

(iii)    an underwriter or member of a banking or selling group acting in such capacity that becomes the Beneficial Owner of fifty
percent (50%) or more of the Voting Shares in connection with a distribution of securities pursuant to an underwriting agreement

Corporation’s Board of Directors, such acquisition shall be deemed not to have occurred for the purposes hereof. Any such waiver
may only be given on the condition that such Person, within ten (10) days after the foregoing determination by the Corporation’s
Board of Directors or such later date as the Corporation’s Board of Directors may determine (the “Disposition Date”), has reduced
its  Beneficial  Ownership  of  Voting  Shares  such  that  the  Person  is  no  longer  an  Acquiring  Person  and  such  waiver  shall  only  be
effective if the reduction has occurred within such ten (10) day or longer period.

(c)        Person  means  any  individual,  firm,  partnership,  association,  trust,  trustee,  executor,  administrator,  legal  personal

hereof, are the common shares of the capital of the Corporation.

(f)        Voting  Share  Reduction  means  an  acquisition  or  redemption  by  the  Corporation  or  any  corporation  controlled  by  the
Corporation  of  Voting  Shares  which,  by  reducing  the  number  of  Voting  Shares  of  the  Corporation  outstanding,  increases  the

Colleagues,

Aeterna Zentaris Inc. (the “Company”) is committed to conducting business with the highest degree of ethics, integrity, and compliance with laws
worldwide. In fact, we shall all strive to reasonably exceed the letter of the law to create the culture of a values-based company. I am proud to
present an updated version of the AEterna Zentaris Inc. Code of Conduct and Business Ethics (“Code”), which reflects the Company’s commitment
to integrity and a values-based culture.

It is essential that we remain committed to the highest standards of legal compliance and ethical business conduct. As such, the Code is designed to
require that we act with unwavering integrity and the highest ethical standards.

The Company is committed to complying with all applicable laws and regulations governing our business and our pharmaceutical products. Aeterna
Zentaris also follows the PhRMA Code on Interactions with Healthcare Professionals. Employees are expected to read, understand, and abide by all
of these policies, the Code, and other relevant policies and procedures.

All of us has a critical role to play in the lawful and ethical conduct of our business. We want all colleagues to take the time to understand the
principles behind the laws and regulations that underlie these important Company policies. These policies are so important to the Company that
adherence to them will be considered in connection with all employee performance evaluations.

If you ever have questions about the operation of these policies, or have concerns about known or suspected violations of these policies, we expect
you to raise them with your supervisor, Human Resources, or even anonymously via the Company’s Ethics and Compliance Hotline, as more fully-
detailed in the Code.

We are all individually responsible for protecting the business and reputation of Aeterna Zentaris and following this Code in our daily conduct will
serve as the cornerstone of a values-based culture.

Thank you for your continued contributions to the growing success of Aeterna Zentaris.

Sincerely,

Michael V. Ward

How to Use this Code of Conduct

This Code applies to every employee, contractor, officer and director of Aeterna Zentaris Inc. and its subsidiaries (“Company”). Third
parties acting on behalf of the Company are also expected to act within the framework and tenor of this Code. Every employee, contractor,
officer and director should become familiar with the contents of this Code of Conduct and act in accordance with its terms. This Code will
also be applied in accordance with applicable local laws and regulations.

This Code only provides general guidance and is not an exhaustive document anticipating every situation encountered in our daily
commercial activities. Rather, this Code highlights the guiding principles that form the basis of the Company’s conduct and its other
policies.

The Company will provide appropriate training to ensure that all participants are familiar with the terms of this Code.

Employees are encouraged to ask questions when they need clarity and to speak up when they have ethical or compliance concerns.

This Code is intended to exceed requirements for a code of ethics under the Sarbanes-Oxley Act of 2002 (and the related regulations
adopted by the Securities and Exchange Commission) and applicable Marketplace Rules of The Nasdaq Stock Market, Inc.

This replaces and supersedes the Code of Ethical Conduct that was previously approved on March 10, 2009.

Ethics and Integrity in the Workplace

Health and Safety in the Workplace

High safety standards and the constant improvement thereof are an integral part of the Company’s ethics and commitment. The Company
provides safe and healthy working conditions on its sites for both its employees and contractors. Each employee is expected to contribute to
the safety of the workplace by being aware of the rules, policies and procedures and by reporting any unsafe condition.

Equal Opportunity and Non-Discrimination

All employees should respect one another and treat each other with respect, without regard to race, color, national or ethnic origin, ancestry,
age, religion or religious creed, disability or handicap, sex or gender, sexual orientation, military or veteran status, genetic information, or
any other characteristic protected under applicable federal, state or local law. Unlawful discrimination will not be tolerated.

Harassment-Free Environment

The Company strives to maintain a work environment in which people are treated with dignity, decency and respect. That environment
should be characterized by mutual trust and the absence of intimidation, oppression and exploitation. Employees should be able to work and
to learn in a safe and stimulating atmosphere. The accomplishment of this goal is essential to the Company’s mission.

An Open Dialogue with Employees

The Company is committed to maintaining trusting and constructive relations with its employees. This exchange is particularly important as
the employees are the key players in the Company’s responsible performance. The Company encourages dialogue between employees and
management to assist employees to identify actual or potential situations that might lead to a violation of this Code and to find solutions to
prevent such situations.

Data Privacy

Personal data can only be collected to serve legitimate purposes and subject to applicable directives, rules and regulations.

Conflict of Interest

Employees shall exercise fair, objective and impartial judgment in all business dealings, placing the interest of the Company over any
personal interest in matters relating to the Company’s business.

Employees must not use their positions to obtain direct or indirect personal benefits. To protect the Company and themselves against even
the appearance of a conflict of interest, employees are encouraged to disclose to their managers any relationship they have with any other
entity with which the Company does business or may potentially do business or with any actual or potential competitor of the Company.
More generally, employees must avoid being involved in any transactions or activities that could be or give rise to a conflict.

Use of Company Resources

Employees are expected to dedicate their working time to the pursuit of the Company’s interests, protecting its assets and making
reasonable use of its resources. The Company understands that its employees may make use of the Company’s resources from time-to-time
to address minor personal matters that cannot be handled outside of normal work hours. Should personal use of the Company’s resources be
authorized, that use must not be excessive, engaged in for personal gain or illegal purposes or otherwise abused.

Communication with the Public

Although the Company respects the private lives and social relations of its employees, any public reference to the Company or its
employees, personally or through any social media, must be consistent with the terms of this Code of Conduct and our Disclosure Policy.
This Code is not intended to preclude or dissuade discussions among employees about topics protected by law. For example, such public
comments may not amount to harassment of another employee.

Ethics and Integrity as a Member of the Healthcare Industry

Overview

The Company is committed to complying with all applicable laws and regulations governing our business and our products. The Company also
supports and subscribes to the PhRMA Code on Interactions with Healthcare Professionals. With these commitments in mind, Company employees
are responsible for conducting business in conformance with these Healthcare Law Compliance Policies and the Company’s Code.

Interacting with Healthcare Community

Interactions with the healthcare community are subject to many laws that restrict the economic benefits given to members of the healthcare
community. The term “healthcare community” generally means any person or entity in a role to purchase, prescribe, administer, recommend or
arrange for the purchase sale or formulary placement of one of the Company’s products. This includes but is not limited to physicians, nurses, office
practice managers, pharmacists, wholesalers and professional organizations. The Company complies with these requirements by ensuring that it does
not improperly influence members of the healthcare community when they make decisions about the use of our products.

It is never permissible to promise or to provide anything of value for the purpose of encouraging or inducing any member of the healthcare
community to purchase, prescribe, use or recommend our products. If it is necessary to compensate any member of the healthcare community for
their services, the amount of compensation must be commensurate with the services provided and reflect fair market value. For example, the
Company is required to report direct and indirect transfers of value, including payments, to any members of the healthcare community. To learn more
about this reporting obligation, please review the Company’s U.S. Sales and Marketing Code of Conduct (Sunshine Act Policy).

Key Healthcare Laws

There are many government enforcement agencies and numerous healthcare laws that regulate the pharmaceutical industry. The Company expects all
employees to have a basic understanding of the regulatory environment in which we operate. Brief descriptions of some of the key agencies and the
laws they enforce are below.

Food and Drug Administration (FDA)

The FDA has wide-ranging authority to regulate drug approval, safety, clinical studies, and product labeling, as well as advertising and promotion for
prescription drugs. It also has at its disposal a host of enforcement tools, including regulatory “Warning Letters,” product seizure, import and export
restriction, and monetary fines.

Centers for Medicare and Medicaid Services (CMS)

The CMS administers the Medicare and Medicaid programs. Medicare is a federal program that provides healthcare coverage for the elderly,
disabled, and persons with end-stage renal disease. Medicaid, which is jointly funded by the federal government and the states and is administered by
the states, is a healthcare program for people with limited income and resources. Both Medicare and Medicaid reimburse for certain pharmaceutical
products.

Other Government Agencies

There are other agencies of the federal government that investigate health- care fraud, such as the Department of Justice (DOJ), Department of
Health and Human Services’ Office of Inspector General (OIG), Drug Enforcement Administration, Federal Bureau of Investigation (FBI),
Department of Defense (DOD), and Department of Veterans Affairs (VA). In addition, almost every state has a Medicaid Fraud Control Unit and/or a
state Medicaid Inspector General to investigate Medicaid issues, and the office of a state attorney general also to investigate any suspected violation
of state law.

The key health regulatory laws that form the basis for the policies set forth in this Code are listed here and summarized below:

•    The Federal Healthcare Anti-Kickback Statute

•    The Federal Civil False Claims Act

•    The Federal Food, Drug, and Cosmetic Act

•    The Civil Monetary Penalties Law

•

Federal Price Reporting Laws (including Medicaid Drug Rebate Statute, Public Health Services Act, and Veterans Health Care Act)

•    The Health Insurance Portability and Accountability Act of 1996

•    The Medicare Drug, Improvement, and Modernization Act of 2003

•    The Physician Payments Sunshine Act (part of the healthcare reform legislation in the Patient Protection and Affordable Care Act of 2010)

Summary of Key Healthcare Laws

FEDERAL HEALTHCARE ANTI-KICKBACK STATUTE

Relevant Purpose

The Federal Anti-Kickback Statute generally prevents companies such as the Company from encouraging customers, directly or indirectly, to

recommend, prescribe, or purchase the Company products based on a financial incentive or “kickback” rather than sound medical judgment.

Summary of the Law

As it applies to the Company, the Anti-Kickback Statute generally makes it illegal to directly or indirectly offer or pay any “remuneration” to any

entity (including vendors, customers, and potential customers) to induce that entity to recommend, prescribe, or purchase Company products when those
products are being paid for by the federal government. “Remuneration” can be anything of value, such as discounts, rebates, grants, vouchers, cash, gifts,
services, coupons, lottery tickets, trips, or free products. The government may view remuneration as a kickback even if one among many other appropriate
reasons you provided it was to encourage your customer to prescribe or order Company products.

Similarly, the Anti-Kickback Statute generally makes it illegal for the Company’s customers and vendors to accept any improper remuneration in

exchange for prescribing or influencing prescribing of the Company products. Thus, there is a common interest between the Company and those individuals
and entities with whom we do business to avoid an arrangement that might appear to be a “kickback.”

“Safe Harbors”

Not all discounts, grants, and gifts are illegal. The government has established “safe harbors” to protect certain conduct. If a manufacturer fully complies with
a safe harbor, it will not be liable under the Anti-Kickback Statute. Four safe harbors are particularly significant to pharmaceutical manufacturers:

•    The Discount Safe Harbor protects certain price reductions, provided they are set in advance and properly disclosed and reported to the government

•    The Personal Services Safe Harbor allows a manufacturer to enter into contracts with healthcare professionals for services such as speaking engagements,
consultancies, and advisory boards. It is important to note that this safe harbor requires that the services be “bona fide” and that any fees paid for such
services represent the “fair market value” for such services

•    The Group Purchasing Organization (GPO) Safe Harbor protects certain administrative fees paid to GPOs

•    The Managed Care Safe Harbor protects certain discount arrangements with managed care organizations

The specifics of these safe harbors are extremely complex. For this reason, all arrangements and contracts for the sale of Company products, including any
discounts or rebate arrangements, as well as all arrangements for paid services, must be approved by the CEO.

Penalties

It is a felony to violate the Anti-Kickback Statute. Violators may be fined substantial penalties for violations, and may also face probation (for organizations)
or prison (for individuals). Additionally, violation of the Anti-Kickback Statute may result in exclusion from the federal healthcare programs such as
Medicare and Medicaid. For the Company, exclusion could mean that our products would no longer be reimbursed by these important federal payors.
Likewise, there are state-based anti-kickback statues under which the Company could face penalties for activities deemed to be kickbacks.

FEDERAL CIVIL FALSE CLAIMS ACT

 
 
Purpose

The government relies on certain information provided by pharmaceutical manufacturers in determining whether and what to pay for certain products and
services under programs such as Medicare and Medicaid. The purpose of the Federal False Claims Act is to prevent the government from paying more than it
should for a product or service because of false or inaccurate information.

Summary

It is illegal to make – or assist others in making – false statements or claims to the government. A claim is “false” if the person or company making the claim
actually knows that it is false or acts in “deliberate ignorance” of, or with “reckless disregard” for, whether the statement or claim is actually true. Under the
False Claims Act, individuals with knowledge of false claims, sometimes called “whistle-blowers,” may bring suit on behalf of the government in so-called
qui tam actions.

Unintentional or honest mistakes are not generally illegal. However, too many “honest mistakes” may suggest that a person or company is not taking care
with the information it provides to the government and which could be viewed as “reckless disregard” of the truth.

If government reimbursement (including but not limited to Medicare or Medicaid reimbursement) for Company products depends on information that the
Company generates or reports, and the Company “knowingly” fails to generate or report such information completely and accurately, or even is negligent in
doing so, the Company may be liable under the False Claims Act.

The following are some other examples of activities that the government may view as false claims:

•
•
•
•
•
•
•

Failing to include the value of discounts and rebates (including “off invoice” discounts) in certain prices reported to the government
Providing “false invoices” to customers to assist them in obtaining a larger government reimbursement than they deserve
Failing to correct the fact that a price provided to the government is clearly inaccurate
Making inadequate efforts to check the accuracy of the prices submitted to the government
Allowing employees with insufficient training and supervision to calculate prices reported to the government
Encouraging a customer to bill inappropriately for a Company product, or
Providing false product information or kickbacks (as described in more detail in other sections of these policies) to formulary committee
members or prescribers in order to get Company products reimbursed by a federal healthcare program

Penalties

Financial penalties for violations of the False Claims Act can be substantial. Moreover, there are other similar state and federal laws that would criminalize
certain false claims. Additionally, violation of the False Claims Act may result in exclusion from federal healthcare programs such as Medicare and Medicaid.
For the Company, exclusion could mean that our products would no longer be reimbursed by these important federal payors.

FEDERAL FOOD, DRUG, AND COSMETIC ACT

Purpose

The ultimate purpose of the Federal Food, Drug, and Cosmetic Act (FDCA) is to protect consumer health. Under the FDCA, the Food and Drug
Administration (FDA) regulates several areas of prescription drug development and marketing, including clinical studies, manufacturing, market approval,
safety and efficacy, and advertising and promotion.

Summary

In order to ensure that any drugs placed on the market are safe and effective, the FDCA requires clinical investigation of a new drug for a particular use.
Clinical studies must be designed and conducted in compliance with applicable industry standards and in such a way as to produce scientifically accurate
data. The FDA may only approve a drug that has been shown to be safe and effective for the use investigated during its clinical trial(s). As such, the Company
may not promote a drug that is currently under clinical investigation. There are limited exceptions to disseminate information concerning a drug before it has
received marketing approval from the FDA. These exceptions must be approved in advance by an outside legal expert approved by the CEO.
Even after a company drug receives approval, the company must control how its drug is promoted. A manufacturer may only promote a drug for its approved
use, even though prescribers may use their professional judgment in determining how to prescribe the drug. Promoting a drug for an unapproved use is known
as “off-label promotion,” meaning that the manufacturer is promoting the drug for a use not indicated in the drug’s approved labeling.

A drug’s “labeling” includes all information contained on its label, packaging, and its full prescribing information (FPI) or package insert (PI), as well as any
other materials distributed by the manufacturer about the drug, and oral statements about the drug’s intended use. Thus, all such materials and statements must
contain only information related to the drug’s approved use(s) as set forth in the FPI. As previously mentioned, there are some narrow exceptions to the off-
label promotion rule, which can be used only when approved by an outside legal expert approved by the CEO.

In addition to promoting a drug only for its approved use(s), a company must promote its drugs in a way that is truthful and not misleading and that gives a
“fair and balanced” description of the drugs’ risks and benefits. This means that risk information must be presented with prominence and readability
comparable to any safety or efficacy information. Fair balance must exist in our printed materials as well as any oral communications of a promotional nature.

The Prescription Drug Marketing Act (PDMA), part of the FDCA, regulates the distribution of prescription drugs. Under the PDMA, manufacturers must
closely track the distribution of prescription drugs, including drug samples. Manufacturers are also prohibited from engaging in any sale of drug samples.

Penalties

Violations of the FDCA, including violations of the PDMA, may result in civil penalties, such as monetary fines or criminal sanctions, including
imprisonment. In order to monitor a manufacturer’s development and marketing of its drugs, FDA uses a variety of enforcement mechanisms. Such
mechanisms may include conducting on-site facility inspections to ensure compliance with Good Manufacturing Practice and Quality Systems regulations,
issuing “Warning Letters” or “Untitled Letters” if any deficiencies or regulatory violations are found with respect to product manufacturing or promotion,

 
seizing products or withdrawing products from the market, and debarring individuals or companies from drug manufacturing or other FDA-regulated
activities.

FEDERAL PRICE REPORTING LAWS

Purpose

State and federal laws (including the Medicaid Drug Rebate Statute, Public Health Services Act, Veterans Health Care Act, and Medicare Modernization Act
(MMA) require the Company to report drug prices on a regular basis as a condition of its drugs being covered by various government reimbursement
programs (such as Medicaid).

Summary

There are complex rules governing the calculation of the pricing metrics that need to be reported to the government. Among other things, the following
arrangements must, at a minimum, be considered by the Finance and the Commercial Organization of the Company when reporting prices to the government:
discounts (regardless of how they are noted or characterized), rebates, any price concessions, fees, credits, settlements of accounts receivables, provision of
free goods contingent upon a sale of Company products, reduced price services, or grants intended to lower the price of a drug.

Penalties

Reporting inaccurate pricing information can lead to various civil and criminal penalties under the relevant laws. For example, penalties may be available
under the Federal Civil False Claims Act, discussed in greater detail above. Additionally, penalties may be imposed under the government price reporting
statutes themselves, and such penalties may include monetary fines, as well as potential criminal liability. Finally, The Company’s products may be excluded
from coverage under most federal and state healthcare programs for violation of these price reporting laws.

Discounts, rebates, and other requests to lower the ultimate price of a The Company product to a customer must be approved by the [Vice President and Chief
Commercial Officer] with the concurrence of an outside legal expert approved by the CEO].

CIVIL MONETARY PENALTIES LAW

Purpose

The Civil Monetary Penalties Law provides the OIG with the authority to impose civil monetary penalties (CMPs) for various activities involving the federal
healthcare programs. These penalties are in addition to those penalties that might be available under other federal statutes, such as those discussed previously.

Summary

The Civil Monetary Penalties Law provides for the imposition of CMPs against any person (including an organization or other entity) for various activities,
including:

•
•
•

•

knowingly presenting, or causing to be presented, false or improper claims to a state or federal government employee or agent
violating the Federal Healthcare Anti-Kickback Statute
engaging in certain arrangements or contracts with entities or individuals who have been excluded from participation in federal healthcare
programs, and
providing certain financial incentives or inducements to individual beneficiaries of federal healthcare programs

Penalties

CMPs are civil fines that can be imposed in addition to any civil or criminal liability under the other laws discussed in these policies.

HIPAA—PRIVACY OF MEDICAL INFORMATION

Purpose
The purpose of the Health Insurance Portability and Accountability Act of 1996 (HIPAA) is to protect personal health information from disclosure to
unauthorized persons.

Summary

HIPAA requires certain companies (known as Covered Entities) to take precautions when using or disclosing confidential health information under certain
circumstances. “Covered Entities” may include physicians, pharmacies, health plans and others with whom we do business. With the possible exception of
certain employee benefit plans, The Company is not a “Covered Entity.” However, it is important that all The Company employees recognize that our
customers may be restricted from sharing certain health information with us, particularly if such information might identify any individual patients.

In many circumstances, Covered Entities must obtain permission before they can use or disclose protected health information. Even in situations where
permission is unnecessary, companies must still follow certain rules in using or disclosing this confidential data. HIPAA also allows individuals to learn what
information has been collected about them by Covered Entities and what will happen to that information.

In the context of adverse event reporting, HIPAA specifically permits disclosure of personally identifiable information that is relevant to the report.

HIPAA’s requirements are extremely complex. Any questions about The Company’s privacy policies and procedures should be directed to an outside legal
expert approved by the CEO.

Penalties

 
 
 
HIPAA violations are criminal and are punishable by substantial monetary fines, as well as possible jail time (for an individual) and probation (for an
organization).

Note: Laws relating to personal health and privacy may be more restrictive in other countries of the European Union

THE MEDICARE DRUG, IMPROVEMENT, AND MODERNIZATION ACT OF 2003

Purpose

The Medicare Drug, Improvement, and Modernization Act of 2003 (MMA) established a Medicare outpatient prescription drug benefit program, among other
things.

Summary

The MMA created Medicare Part D as an outpatient prescription drug benefit administered by private entities. Part D drug benefits may be made available
through entities offering stand-alone prescription drug benefit plans (known as “prescription drug plans” or PDPs), through managed care plans that offer a
more comprehensive healthcare benefit (known as “Medicare Advantage Plans” or MA-PDs), and a variety of other arrangements. Discounts and rebates to
PDPs and MA-PDs are not included in Medicaid Best Price calculations.

Penalties

Although most penalties that may be assessed under Part D do not apply to The Company, the federal money used for Part D drugs brings the program within
the purview of the other laws discussed above.

Some activities that may generate scrutiny by the Centers for Medicare and Medicaid Services (CMS) include:

•    Failure to generate, report, or document Part D rebate or discount information completely and accurately
•    Kickbacks, inducements, and other illegal remuneration
•

Inappropriate relationships with formulary committee members, payments to pharmacy benefits managers (PBMs), and formulary placement
payments in order to have manufacturer’s products included on a plan’s formulary
Inappropriate relationships with physicians, including “switching” arrangements, certain services payments, gratuities, and improper entertainment,
and
Illegal off-label promotion

•

•

Additionally, it is important to keep as much separation as possible between discussions of Part D rebates and discounts and discussions of commercial
rebates and discounts, as it would be inappropriate to “swap” between programs (e.g., offer higher discounts to Part D in order to win a company’s
commercial business or vice versa).

THE PHYSICIAN PAYMENTS SUNSHINE ACT

Purpose

The Sunshine Act provisions of the Patient Protection and Affordable Care Act seek to provide increased transparency on interactions between physicians and
teaching hospitals and the pharmaceutical, biologics, and medical device industries.

Summary

Manufacturers must report payments or other transfers of value to physicians and teaching hospitals annually. Reports must be filed by March 31st each year,
reflecting all payments and transfers of value to physicians and teaching hospitals for the previous calendar year. The Secretary of Health and Human
Services will make reported information publicly available in a searchable format by June 30th of each year. It is extremely important that Company
employees (and certain contractors) responsible for making such payments or transfers of value accurately report such transfers.

The Finance Department will service as data stewards, aggregating data and reporting it, but the completeness and accuracy of data are the responsibility of
the employees/contractors involved in the payments or transfers of value.

Penalties

Manufacturers that fail to report in a timely and accurate manner may be subject to significant civil monetary penalties.

Promoting Products

The way the Company promotes and markets its products is subject to regulation in every country in which it operates. To comply with the
regulations, the Company carefully controls the form and content of all promotional materials. It is never permissible to use promotional materials
other than those that have been approved by the Company. You may never create your own promotional materials or modify materials that have been
approved. Be sure that your promotional discussions are complete, accurate and not misleading when you promote the Company’s products. Never
promote an off-label use of the Company’s products. All products claims must be consistent with approved labeling and prescribing information.
When discussing the Company’s products, always describe all safety information fully and accurately and never misrepresent or minimize it.

Pricing and Price Reporting

Accurate and timely pricing information assists not only the Company but government agencies, private payors, healthcare professionals, patients
and other stakeholders. This type of information is also important to our commercial success and to meeting our legal and regulatory requirements.

 
Therefore, all employees are expected to ensure that the government price calculations and reports that they produce are timely and accurate. All
employees are expected to follow the Company’s procedures for obtaining approval for, documenting, and communicating lawful discounts, rebates
and administrative fees.

Good Operating Practices

The Company adheres to sound scientific and quality principles and ensures that these principles are reflected in its operations. To uphold the
principles, the Company complies with all applicable laws dealing with current Good Laboratory Practices (cGLP), Good Clinical Practices (cGCP),
Good Manufacturing Practices (cGMP) and Good Distribution Practices (cGDP). The Company refers to these practices collectively as current Good
Operating Practices (cGxP). The Company has adopted systems and internal controls for all cGxP areas or it has contracted with other entities to
provide services that are compliant with cGxP.

All employees are expected to know the relevant compliance policies and procedures that apply to their respective cGxP responsibilities and to
participate in training regarding the policies. It is never appropriate to take shortcuts in complying with any cGxP policy or procedure. Doing so
could invalidate a batch of product and subject the Company to regulatory enforcement actions. All employees are expected to cooperate with all
assessments and tests designed to ensure GxP compliance and to report to their respective managers any deviations from cGxP policies and
procedures.

Drug Safety – Reporting Adverse Events, Product Complaints and other Safety Findings

The Company is committed to compliance with all laws and regulations that require it to collect and review information regarding adverse events,
product complaints and other safety findings. If you become aware of any adverse event, product complaint or other safety finding experienced by a
patient or a trial subject taking an approved or investigational product, you are required to notify the Company’s Chief Medical Officer within one
business day.

Government Inspections and Requests

The Company’s facilities and activities are likely to be inspected by representatives of government agencies from time-to-time. The Company is
committed to being cooperative with government representatives conducting such inspections. All employees are expected to provide a positive and
cooperative environment for inspectors throughout the inspection and to respond to inquiries truthfully to the best of their abilities. It is never
permissible to make false or misleading statements to any government representative. Doing so will result in severe disciplinary action. If an
employee does not know the answer to a question posed by a government representative, the appropriate course of action is to say so and to tell the
representative that the answer will be obtained promptly.

Scientific Exchange

“Scientific Exchange” refers to the bona fide exchange of medical and scientific information in a non-promotional manner or context. It also refers to
a response to an unsolicited question or request for information from a healthcare professional or institution. As such, scientific exchange is an
important part of the Company’s business. Employees involved in scientific exchange are required to use information that is truthful and not
misleading and that is non-promotional in its nature and intent.

Ethics and Integrity in Doing Business

Financial Records and Accounting

The Company accurately informs its shareholders of all actions, events or decisions reasonably likely to have a significant effect on their
investment decisions. The Company’s books and records must always reflect actual financial information consistent with International
Financial Reporting Standards. Employees must ensure that the records are accurate and properly retained in accordance with applicable
laws and regulations.

Insider Trading

The Company has a policy governing insider trading. The policy is called the “Insider Trading Compliance Policy.” All employees have
been provided a copy of this policy and all employees are expected to comply with it. In general, the Insider Trading Compliance Policy
provides, among other things, that employees who have access to inside information shall not buy or sell any securities based on that
information or communicate it to someone else who then trades in those securities. This concerns securities of the Company and of third
parties. Inside information means information that has not yet been made public and that if it were made public would likely have a
significant impact on the trading price of the securities.

Proprietary and Confidential Information

Each employee and contractor of the Company shall execute a “Confidentiality and Proprietary Rights Agreement.” In general, this
agreement imposes restrictions on the disclosure of the Company’s and other third parties confidential and proprietary information both
within and outside the Company. Employees must take precautions to safeguard the Company’s proprietary information from disclosure to
competitors and other unauthorized third parties. In addition to safeguarding the Company’s confidential information, employees must also
take care to protect the confidential information of third parties (for example customers and suppliers) that comes into their possession.

Fair Competition

The Company wants to succeed ethically and with the highest integrity. The Company values fair and open competition and must comply
with all competition and antitrust laws. The Company does not enter business arrangements that distort, eliminate or discourage competition

or that provide improper competitive advantages. The Company strives to succeed fairly and honorably.

Supply Chain

The Company expects its vendors, suppliers and customers to obey all laws and regulations governing their activities, both within their own
worksites and the Company’s. They are also contractually encouraged to adhere to the spirit of this Code of Conduct in their operations.

The Company applies a structured, fair and ethical process to select and to evaluate its suppliers to build a mutually beneficial relationship
with them. Our suppliers are selected based on objective criteria such as quality, reliability, competitive pricing and commitments to ethical
behavior.

Gifts, Bribes and Kickbacks

Other than gifts of nominal value given or received in the normal course of business (e.g., business lunches), neither you, nor your relatives,
may give gifts to, or receive gifts from, patients, customers or suppliers. Other gifts may be given or accepted with prior approval of the
CEO.

A kickback or bribe is the offering of an item to a person with the intent to obtain favorable treatment. Any employee who pays or receives
a bribe or kickback will be immediately terminated and reported, as warranted, to the appropriate authorities.

Ethics and Integrity as a Corporate Citizen

Political Contributions

The Company does not take part in political activities nor does it make corporate donations to political parties or to candidates. The Company
respects the freedom of its employees to make their own political decisions. Any personal participation or involvement by an employee in the
political process must be on an individual basis, on the employee’s own time and at the employee’s personal expense.

Supporting the Code of Conduct – Speak Up

How to Speak Up

The first and best place for employees to Speak Up is with their individual manager. In fact, part of the manager’s job is to listen to employees,

The Company prefers that human resources issues be handled at the local level. Employees are encouraged to speak with someone in their local
management or Human Resources staff, if possible, to try to resolve their issues before filing a report. If the issue has not been addressed after a
reasonable amount of time, employees are encouraged to make a report. No matter how concerns are reported – whether anonymously or by name, in
person or through EthicsPoint – employees can be assured confidentiality will be maintained to every extent possible. Limited disclosures will be
made only to facilitate investigation or where required by law. All reports will be investigated and all investigations will be conducted in a manner
that reflects the Company’s values, its respect for the rights of all parties involved and applicable law.

No Retaliation

In no event shall an employee who makes a report be subject to retaliation. Any person, regardless of position, who engages in retaliatory behavior
will be subject to disciplinary action. If reports are made in good faith, no action will be taken against an employee raising a concern that eventually
proves to be inaccurate. However, abusive accusations will not be tolerated.

The Company expects every employee to support this Code and encourages every employee to Speak Up for what is right when there is something
wrong.

Annual Certification of the Code of Conduct

Training and Awareness

To ensure understanding and compliance, all employees will receive a copy of this Code on an annual basis to certify their acceptance and
understanding of the Code and its requirements. The Company will provide updates and training for new laws and regulations as well.
Employees should review their behavior considering this Code and determine whether changes are required. At the same time, all managers
and supervisors should actively communicate about this Code, monitor compliance and act as positive role models.

Enforcement

Violations of the Code will not be tolerated. Employees are encouraged to speak up when behavior inconsistent with the Code is observed
and managers are expected to deal with such reports and, if necessary, to refer them to the appropriate member of management and/or
compliance officer. Violations can lead to disciplinary action, up to and including termination of employment, consistent with applicable
laws and regulations.
