GENERAL

On July 10, 2007 (the ”Arrangement Date”), the Company completed a plan of arrangement and corporate reorganization with, among others, 4325231 Canada Inc.
(now Global Summit Real Estate Inc.), formerly Lorus Therapeutics Inc. (“Old Lorus”), 6707157 Canada Inc. and Pinnacle International Lands, Inc. (the “Arrangement”). As
a result of the plan of arrangement and reorganization, among other things, each common share of Old Lorus was exchanged for one common share (“Common Share”) of the
Company and the assets (excluding certain deferred tax assets) and liabilities of Old Lorus (including all of the shares of its subsidiaries) were transferred, directly or indirectly,
to  the  Company  and/or  our  subsidiaries.  We  continued  the  business  of  Old  Lorus  after  the Arrangement  Date  with  the  same  officers  and  employees  and  continued  to  be
governed by the same directors as Old Lorus prior to the Arrangement Date.

On August 28, 2014 (the “Name Change Date”), we changed our name from Lorus Therapeutics Inc. to Aptose Biosciences Inc. In this Annual Report on Form 20-F,
all references to “Aptose”, the “Company”, “we”, “our”, “us” and similar expressions, unless otherwise stated, are references to Old Lorus prior to the Arrangement Date,
Lorus Therapeutics Inc. after the Arrangement Date and Aptose Biosciences Inc. after the Name Change Date. References to this “Form 20-F” and this “Annual Report” mean
references to this Annual Report on Form 20-F dated as of March 28, 2017 for the twelve months ended December 31, 2016.

We use the Canadian dollar as our reporting and functional currency. All references in this Annual Report to “dollars” or “$” are expressed in Canadian dollars, unless
otherwise  indicated.  See  also  “Item  3.  Key  Information  -  Exchange  Rate  Information”  for  more  detailed  currency  and  conversion  information.  Our  consolidated  financial
statements, which form part of this Annual Report, are presented in Canadian dollars and are prepared in accordance with International Financial Reporting Standards as issued
by the International Accounting Standards Board (“IFRS”), which differ in certain respects from accounting principles generally accepted in the United States (“U.S. GAAP”).

On  October  1,  2014,  we  consolidated  our  outstanding  Common  Shares  on  the  basis  of  one  post-consolidation  Common  Share  for  each  twelve  pre-consolidation

Common Shares. Historical trading prices and volumes disclosed are on a post-consolidated basis and reflect the one for twelve.

This Annual  Report  contains  forward-looking  statements  within  the  meaning  of  the  United  States  Private  Securities  Litigation  Reform Act  of  1995  or  “forward-

looking information” (within the meaning of applicable Canadian securities legislation). Such statements include, but are not limited to, statements relating to:

The forward-looking statements reflect our current views with respect to future events, are subject to significant risks and uncertainties, and are based upon a number of
estimates and assumptions that, while considered reasonable by us, are inherently subject to significant business, economic, competitive, political and social uncertainties and
contingencies. Many factors could cause our actual results, performance or achievements to be materially different from any future results, performance, or achievements that

our ability to obtain the substantial capital we require to fund research and operations;

our lack of product revenues and history of operating losses;

our  early  stage  of  development,  particularly  the  inherent  risks  and  uncertainties  associated  with  (i)  developing  new  drug  candidates  generally,  (ii)  demonstrating  the
safety and efficacy of these drug candidates in clinical studies in humans, and (iii) obtaining regulatory approval to commercialize these drug candidates;

our drug candidates require time-consuming and costly preclinical and clinical testing and regulatory approvals before commercialization;

clinical studies and regulatory approvals of our drug candidates are subject to delays, and may not be completed or granted on expected timetables, if at all, and such
delays may increase our costs and could delay our ability to generate revenue;

our ability to attract and retain key personnel;

our ability to obtain and maintain patent protection;

our ability to protect our intellectual property rights and not infringe on the intellectual property rights of others;

development or commercialization of similar products by our competitors, many of which are more established and have or have access to greater financial resources
than us;

commercialization limitations imposed by intellectual property rights owned or controlled by third parties;

our business is subject to potential product liability and other claims;

potential exposure to legal actions and potential need to take action against other entities;

our ability to maintain adequate insurance at acceptable costs;

further equity financing may substantially dilute the interests of our shareholders;

changing market conditions; and

other risks detailed from time-to-time in our on-going quarterly filings, annual information forms, annual reports and annual filings with Canadian securities regulators
and the United States Securities and Exchange Commission (“SEC”), and those which are discussed under the heading “Item 3. Key Information—D. Risk Factors” in
this document.

Should one or more of these risks or uncertainties materialize, or should the assumptions set out in the section entitled “Item 3. Key Information—D. Risk Factors”
underlying those forward-looking statements prove incorrect, actual results may vary materially from those described herein. These forward-looking statements are made as of
the date of this Annual Report or, in the case of documents incorporated by reference herein, as of the date of such documents, and we do not intend, and do not assume any
obligation, to update these forward-looking statements, except as required by law. Such statements may not prove to be accurate as actual results and future events could differ
materially  from  those  anticipated  in  such  statements.  Investors  are  cautioned  that  forward-looking  statements  are  not  guarantees  of  future  performance  and  accordingly
investors are cautioned not to put undue reliance on forward-looking statements due to the inherent uncertainty therein. New factors emerge from time to time, and it is not
possible for management of the Company to predict all of these factors or to assess in advance the impact of each such factor on the Company’s business or the extent to which
any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statement.

Risk factors.

Investing in our securities involves a high degree of risk. Before making an investment decision with respect to our Common Shares, you should carefully consider the
following risk factors, in addition to the other information included or incorporated by reference in this Annual Report. Additional risks not currently known by us or that we
consider immaterial at the present time may also impair our business, financial condition, prospects or results of operations. If any of the following risks occur, our business,
financial condition, prospects or results of operations would likely be materially adversely affected. In that case, the trading price of our Common Shares could decline and you
may lose all or part of the money you paid to buy our Common Shares. The risks set out below are not the only risks and uncertainties we currently face; other risks may arise in
the future.

We have a history of operating losses. We expect to incur net losses and we may never achieve or maintain profitability.

RISKS RELATED TO OUR BUSINESS

We have not been profitable since our inception in 1986. We reported net losses of $18.7 million in the fiscal year ended December 31, 2016, $14.6 million in the
fiscal year ended December 31, 2015, $7.8 million in the 7 months ended December 31, 2014 and $10.6 million in the fiscal year ended May 31, 2014, and as of December 31,
2016, we had an accumulated deficit of $252 million.

We have not generated any significant revenue to date and it is possible that we will never have sufficient product sales revenue (if any) to achieve profitability. We
expect to continue to incur losses for at least the next several years as we or our collaborators and licensees pursue clinical trials and research and development efforts. To
become profitable, we, either alone or with our collaborators and licensees, must successfully develop, manufacture and market our current product candidates APTO-253 or
CG’806 as well as continue to identify, develop, manufacture and market new product candidates. It is possible that we will never have significant product sales revenue or
receive royalties on our licensed product candidates. If funding is insufficient at any time in the future, we may not be able to develop or commercialize our products, take
advantage of business opportunities or respond to competitive pressures.

We currently do not earn any revenues from our drug candidates and are therefore considered to be in the development stage. The continuation of our research and
development activities and the commercialization of the targeted therapeutic products are dependent upon  our  ability  to  successfully  finance  and  complete  our  research  and
development  programs  through  a  combination  of  equity  financing  and  payments  from  strategic  partners.  We  have  no  current  sources  of  significant  payments  from  strategic
partners.

We are an early stage development company.

We are at an early stage of development. In the past five years, none of our potential products has obtained regulatory approval for commercial use and sale in any
country and as such, no significant revenues have resulted from product sales. Significant additional investment will be necessary to complete the development of any of our
product candidates. Preclinical and clinical trial work must be completed before our potential products could be ready for use within the markets that we have identified. We
may  fail  to  develop  any  products,  obtain  regulatory  approvals,  enter  clinical  trials  or  commercialize  any  products.  We  do  not  know  whether  any  of  our  potential  product
development efforts will prove to be effective, meet applicable regulatory standards, obtain the requisite regulatory approvals, be capable of being manufactured at a reasonable
cost  or  be  accepted  in  the  marketplace.  We  also  do  not  know  whether  sales,  license  fees  or  related  royalties  will  allow  us  to  recoup  any  investment  we  make  in  the
commercialization of our products.

The product candidates we are currently developing are not expected to be commercially viable for at least the next several years and we may encounter unforeseen

difficulties or delays in commercializing our product candidates. In addition, our potential products may not be effective or may cause undesirable side effects.

Our  product  candidates  require  significant  funding  to  reach  regulatory  approval  assuming  positive  clinical  results.  For  example,  our  clinical  candidate APTO-253
began enrolment in a Phase I clinical trial in patients with relapsed or refractory hematologic malignancies and was placed on clinical hold by the United States Food and Drug
Administration (“FDA”) following a voluntary suspension of dosing by us. We are currently working with the FDA to have such hold lifted but significant additional funding or
a partnership will be necessary to complete, if required, Phase II or Phase III clinical trials. Such funding for our product candidates may be difficult, or impossible to raise in
the  public  or  private  markets  or  through  partnerships.  If  funding  or  partnerships  are  not  readily  attainable,  the  development  of  our  product  candidates  may  be  significantly
delayed or stopped altogether. The announcement of a delay or discontinuation of development would likely have a negative impact on our share price.

We need to raise additional capital.

We  have  an  ongoing  need  to  raise  additional  capital.  To  obtain  the  necessary  capital,  we  must  rely  on  some  or  all  of  the  following:  additional  share  issues,  debt
issuances  (including  promissory  notes),  collaboration  agreements  or  corporate  partnerships  and  grants  and  tax  credits  to  provide  full  or  partial  funding  for  our  activities.
Additional funding may not be available on terms that are acceptable to us or in amounts that will enable us to carry out our business plan.

Our need for capital may require us to:

·
·
·

·
·
·
·
·

engage in equity financings that could result in significant dilution to existing investors;
delay or reduce the scope of or eliminate one or more of our development programs;
obtain funds through arrangements with collaborators or others that may require us to relinquish rights to technologies, product candidates or products that we
would otherwise seek to develop or commercialize ourselves;
license rights to technologies, product candidates or products on terms that are less favourable to us than might otherwise be available;
utilize investigator-sponsored or government-sponsored clinical trials that are not under our control;
collaborate with academic groups that have the ability to publish findings with our product candidates without our ability to prevent such publications;
considerably reduce operations; or
cease our operations.

Delays in clinical testing could result in delays in commercializing our product candidates and our business may be substantially harmed.

We cannot predict whether any clinical trials will begin as planned, will need to be restructured or will be completed on schedule, or at all. Our product development
costs  will  increase  if  we  experience  delays  in  clinical  testing.  Significant  clinical  trial  delays  could  shorten  any  periods  during  which  we  may  have  the  exclusive  right  to
commercialize our product candidates or allow our competitors to bring products to market before us, which would impair our ability to successfully commercialize our product
candidates and may harm our financial condition, results of operations and prospects. The recommencement and completion of clinical trials for our products, including the
APTO-253 phase I clinical trial and the IND submission for CG’806, may be delayed for a number of reasons, including delays related, but not limited, to:

•
•
•

•
•
•
•
•
•
•
•

•

  failure by regulatory authorities to grant permission to proceed or placing the clinical trial on hold;
  patients failing to enroll or remain in our trials at the rate we expect;
  suspension or termination of clinical trials by regulators for many reasons, including concerns about patient safety or failure of our contract manufacturers to comply

with cGMP requirements;

  any changes to our manufacturing process that may be necessary or desired;
  delays or failure to obtain GMP-grade clinical supply from contract manufacturers of our products necessary to conduct clinical trials;
  product candidates demonstrating a lack of safety or efficacy during clinical trials;
  patients choosing an alternative treatment for the indications for which we are developing any of our product candidates or participating in competing clinical trials;
  patients failing to complete clinical trials due to dissatisfaction with the treatment, side effects or other reasons;
  reports of clinical testing on similar technologies and products raising safety and/or efficacy concerns;
  competing clinical trials and scheduling conflicts with participating clinicians;
  clinical investigators not performing our clinical trials on their anticipated schedule, dropping out of a trial, or employing methods not consistent with the clinical

trial protocol, regulatory requirements or other third parties not performing data collection and analysis in a timely or accurate manner;

  failure of our contract research organizations, or CROs, to satisfy their contractual duties or meet expected deadlines;

4

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

•

•

  inspections of clinical trial sites by regulatory authorities or Institutional Review Boards, or IRBs, or ethics committees finding regulatory violations that require us

to undertake corrective action, resulting in suspension or termination of one or more sites or the imposition of a clinical hold on the entire study;

  one or more IRBs or ethics committees rejecting, suspending or terminating the study at an investigational site, precluding enrollment of additional subjects, or

withdrawing its approval of the trial; or

  failure to reach agreement on acceptable terms with prospective clinical trial sites.

Our product development costs will increase if we experience delays in testing or approval or if we need to perform more or larger clinical trials than planned.

Additionally, changes in regulatory requirements and policies may occur, and we may need to amend study protocols to reflect these changes. Amendments may require us to
resubmit our study protocols to regulatory authorities or IRBs or ethics committees for re-examination, which may impact the cost, timing or successful completion of that trial.
Delays or increased product development costs may have a material adverse effect on our business, financial condition and prospects.

We rely on contract manufacturers over whom we have limited control. If we are subject to quality, cost or delivery issues with the preclinical and clinical grade

materials supplied by contract manufacturers, our business operations could suffer significant harm.

We rely on contract manufacturing organizations, or CMOs, to manufacture our product candidates for some preclinical studies and clinical trials. We rely on CMOs
for manufacturing, filling, packaging, storing and shipping of drug product in compliance with cGMP regulations applicable to our products. The FDA ensures the quality of
drug  products  by  carefully  monitoring  drug  manufacturers’  compliance  with  cGMP  regulations.  The  cGMP  regulations  for  drugs  contain  minimum  requirements  for  the
methods, facilities and controls used in manufacturing, processing and packing of a drug product.

We contracted with multiple CMOs for the manufacture of APTO-253 and CG’806 to supply drug supply and then drug product for our clinical trials. The synthesis of
CG’806 drug supply is challenging from a scale-up synthetic chemistry perspective. The formulation and manufacture of APTO-253 is a complex process with many variables
involved.  We  pre-qualified  CMOs  to  have  the  capacity,  the  systems  and  the  experience  to  supply  CG’806  and  APTO-253  for  our  clinical  trials.  We  have  qualified  the
manufacturing facilities and the FDA has also performed site audits for our selected CMOs. In spite of the efforts to prequalify CMOs, delays and errors may occur, and any
such manufacturing failures, delays or compliance issues could cause delays in the completion of our clinical trial programs.

There can be no assurances that CMOs will be able to meet our timetable and requirements. We have contracted with alternate suppliers in the event our current CMOs
are unable to scale up production, or if our current CMOs otherwise experience any other significant problems in the manufacture of CG’806 and APTO-253. However, it is
possible that all third-party manufacturing sources may experience failure or delays and may demand commercially unreasonable terms, which may lead to further delays in the
development of our product candidates. Further, contract manufacturers must operate in compliance with cGMP and failure to do so could result in, among other things, the
disruption of product supplies. Our dependence upon third parties for the manufacture of our products may adversely affect our profit margins and our ability to develop and
deliver products on a timely and competitive basis.

Clinical trials are long, expensive and uncertain processes and the FDA or Health Canada may ultimately not approve any of our product candidates. We may

never develop any commercial drugs or other products that generate revenues.

In  the  past  five  years,  none  of  our  product  candidates  has  received  regulatory  approval  for  commercial  use  and  sale  in  North  America.  We  cannot  market  a
pharmaceutical product in any jurisdiction until it has completed thorough preclinical testing and clinical trials in addition to that jurisdiction’s extensive regulatory approval
process. Approval in one country does not assure approval in another country. In general, significant research and development and clinical studies are required to demonstrate
the safety and effectiveness of our product candidates before we can submit any regulatory applications.

Clinical trials are long, expensive and uncertain processes. Clinical trials may not be commenced or completed on schedule and the FDA or Health Canada or any other
regulatory body may not ultimately approve our product candidates for commercial sale. The clinical trials of any of our drug candidates could be unsuccessful, which would
prevent us from advancing, commercializing or partnering the drug.

Even  if  the  results  of  our  preclinical  studies  or  clinical  trials  are  initially  positive,  it  is  possible  that  we  will  obtain  different  results  in  the  later  stages  of  drug
development or that results seen in clinical trials will not continue with longer term treatment. Positive results in Phase I clinical trials may not be repeated in larger Phase II or
Phase III clinical trials.

Our preclinical studies and clinical trials may not generate positive results that will allow us to move towards the commercial use and sale of our product candidates.
Furthermore, negative preclinical or clinical trial results may cause our business, financial condition, or results of operations to be materially adversely affected. For example,
our Phase Ib clinical trial of APTO-253 in patients with AML was placed on clinical hold by the FDA in November 2015 and since that time the Company has encountered
manufacturing setbacks which have further delayed the return of APTO-253 to the clinic. There can be no assurance that the clinical hold will be lifted by the FDA, that the
Company  will  have  the  resources,  or  that  we  will  decide,  to  continue  the  development  of  APTO-253.  Even  if  the  Phase  Ib  of  APTO-253  is  continued,  there  is  a  long
development  path  ahead  that  will  take  many  years  to  complete  and  is  prone  to  the  risks  of  failure  or  delays  inherent  in  drug  development.  Likewise,  our  CG’806  product
candidate has not yet entered clinical trials and it is expected to undergo many years of testing and regulatory examinations prior to any potential regulatory approvals.

Preparing, submitting and advancing applications for regulatory approval is complex, expensive and time intensive and entails significant uncertainty. A commitment

of substantial resources to conduct time-consuming research, preclinical studies and clinical trials is required if we are to complete development of our products.

Clinical  trials  of  our  products  require  that  we  identify  and  enroll  a  large  number  of  patients  with  the  illness  under  investigation.  We  may  not  be  able  to  enroll  a
sufficient  number  of  appropriate  patients  to  complete  our  clinical  trials  in  a  timely  manner,  particularly  in  smaller  indications  and  indications  where  there  is  significant
competition for patients. If we experience difficulty in enrolling a sufficient number of patients to conduct our clinical trials, we may need to delay or terminate ongoing clinical
trials and will not accomplish objectives material to our success. Delays in planned patient enrolment or lower than anticipated event rates in our current clinical trials or future
clinical trials also may result in increased costs, program delays, or both.

In  addition,  unacceptable  toxicities  or  adverse  side  effects  may  occur  at  any  time  in  the  course  of  preclinical  studies  or  human  clinical  trials  or,  if  any  product
candidates are successfully developed and approved for marketing, during commercial use of any approved products. The appearance of any unacceptable toxicities or adverse
side effects could interrupt, limit, delay or abort the development of any of our product candidates or, if previously approved, necessitate their withdrawal from the market.
Furthermore, disease resistance or other unforeseen factors may limit the effectiveness of our potential products.

Our failure to develop safe, commercially viable drugs would substantially impair our ability to generate revenues and sustain our operations and would materially

harm our business and adversely affect our share price.

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

We set goals for, and make public statements regarding, the expected timing of the accomplishment of objectives material to our success, such as the commencement
and completion of clinical trials and our ability to secure the financing necessary to continue the development of our product candidates. The actual timing of these events can
vary dramatically due to factors within and beyond our control, such as delays or failures in our clinical trials, issues related to the manufacturing of drug supply, uncertainties
inherent in the regulatory approval process, market conditions and interest by partners in our product candidates among other things. Our clinical trials may not be completed;
we  may  not  make  regulatory  submissions  or  receive  regulatory  approvals  as  planned;  or  we  may  not  secure  partnerships  for  any  of  our  product  candidates. Any  failure  to
achieve one or more of these milestones as planned would have a material adverse effect on our business, financial condition and results of operations.

6

 
 
 
 
 
 
 
 
 
If we have difficulty enrolling patients in clinical trials, the completion of the trials may be delayed or cancelled.

As our product candidates advance from preclinical testing to clinical testing, and then through progressively larger and more complex clinical trials, we will need to
enroll an increasing number of patients that meet our eligibility criteria. There is significant competition for recruiting cancer patients in clinical trials, and we may be unable to
enroll the patients we need to complete clinical trials on a timely basis or at all. Certain factors that affect enrollment of patients onto our clinical trials are impacted by external
forces that may be beyond our control. Such factors include, but are not limited to, the following:

•
•
•
•
•
•
•

  size and nature of the patient population;
  eligibility and exclusion criteria for the trial;
  design of the study protocol;
  competition with other companies for clinical sites or patients;
  the perceived risks and benefits of the product candidate under study;
  the patient referral practices of physicians; and
  the number, availability, location and accessibility of clinical trial sites.

We rely and will continue to rely on third parties to conduct and monitor many of our preclinical studies and our clinical trials, and their failure to perform as

required could cause substantial harm to our business.

We rely and will continue to rely on third parties to conduct a significant portion of our preclinical and clinical development activities. Preclinical activities include in
vivo  studies  providing  access  to  specific  disease  models,  pharmacology  and  toxicology  studies,  and  assay  development.  Clinical  development  activities  include  trial  design,
regulatory  submissions,  clinical  patient  recruitment,  clinical  trial  monitoring,  clinical  data  management  and  analysis,  safety  monitoring  and  project  management,  contract
manufacturing  and  quality  assurance.  If  there  is  any  dispute  or  disruption  in  our  relationship  with  third  parties,  or  if  they  are  unable  to  provide  quality  services  in  a  timely
manner and at a feasible cost, our active development programs will face delays. Further, if any of these third parties fails to perform as we expect or if their work fails to meet
regulatory requirements, our testing could be delayed, cancelled or rendered ineffective.

We heavily rely on the capabilities and experience of our key executives and scientists and the loss of any of them could affect our ability to develop our products.

The loss of Dr. William G. Rice, our Chairman, President and Chief Executive Officer, or other key members of our staff, including Gregory Chow, our Senior Vice
President and Chief Financial Officer, could harm us. We have employment agreements with Dr. Rice and Mr. Chow, although such employment agreements do not guarantee
their  retention.  We  also  depend  on  our  scientific  and  clinical  collaborators  and  advisors,  all  of  whom  have  outside  commitments  that  may  limit  their  availability  to  us.  In
addition, we believe that our future success will depend in large part upon our ability to attract and retain highly skilled scientific, managerial, medical, clinical and regulatory
personnel, particularly as we expand our activities and seek regulatory approvals for clinical trials. We routinely enter into consulting agreements with our scientific and clinical
collaborators and advisors, key opinion leaders and academic partners in the ordinary course of our business. We also enter into contractual agreements with physicians and
institutions  who  will  recruit  patients  into  our  clinical  trials  on  our  behalf  in  the  ordinary  course  of  our  business.  Notwithstanding  these  arrangements,  we  face  significant
competition for these types of personnel from other companies, research and academic institutions, government entities and other organizations. We cannot predict our success
in hiring or retaining the personnel we require for continued growth. The loss of the services of any of our executive officers or other key personnel could potentially harm our
business, operating results or financial condition.

Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, which could have a

material adverse effect on our business.

We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees could include failures to comply with FDA regulations, provide accurate
information  to  the  FDA,  comply  with  manufacturing  standards  we  have  established,  comply  with  federal  and  state  health-care  fraud  and  abuse  laws  and  regulations,  report
financial information or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry are subject
to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range
of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Employee misconduct could also involve
the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. If any such actions are
instituted  against  us,  and  we  are  not  successful  in  defending  ourselves  or  asserting  our  rights,  those  actions  could  have  a  substantial  impact  on  our  business  and  results  of
operations, including the imposition of substantial fines or other sanctions.

Exchange rate risk

We are exposed to fluctuations of the Canadian dollar against certain other currencies because we publish our consolidated financial statements and hold most of our
investments in Canadian dollars, while we incur many of our expenses in foreign currencies, primarily the United States dollar. Fluctuations in the value of currencies such as
the recent depreciation of the Canadian dollar against the United States dollar 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 Canadian
dollar, the United States dollar and other currencies.

We may expand our business through the acquisition of companies or businesses or by entering into collaborations or by in-licensing product candidates, each of

which could disrupt our business and harm our financial condition.

We may in the future seek to expand our pipeline and capabilities by acquiring one or more companies or businesses, entering into collaborations or in-licensing one or
more  product  candidates.  For  example,  in  June  2016,  we  entered  into  a  definitive  agreement  with  South  Korean  company,  CrystalGenomics,  Inc.  (CG),  granting Aptose  an
exclusive option to research, develop and commercialize CG026806 (CG’806) in all countries of the world except Korea and China, for all fields of use.

Acquisitions, collaborations and in-licenses involve numerous risks, including, but not limited to:

•
•
•
•
•
•
•
•
•
•

  substantial cash expenditures;
  technology development risks;
  potentially dilutive issuances of equity securities;
  incurrence of debt and contingent liabilities, some of which may be difficult or impossible to identify at the time of acquisition;
  difficulties in assimilating the operations of the acquired companies;
  potential disputes regarding contingent consideration;
  diverting our management’s attention away from other business concerns;
  entering markets in which we have limited or no direct experience;
  potential loss of our key employees or key employees of the acquired companies or businesses; and
  failure of the in-licenses agents or technologies to deliver the desired activities or functions.

We have experience in entering collaborations and in-licensing product candidates, however, we cannot provide assurance that any acquisition, collaboration or in-
license will result in short-term or long-term benefits to us. We may incorrectly judge the value or worth of an acquired company or business or in-licensed product candidate.
In addition, our future success would depend in part on our ability to manage the rapid growth associated with some of these acquisitions, collaborations and in-licenses. We
cannot  assure  you  that  we  would  be  able  to  successfully  combine  our  business  with  that  of  acquired  businesses,  manage  a  collaboration  or  integrate  in-licensed  product
candidates. Furthermore, the development or expansion of our business may require a substantial capital investment by us.

Negative results from clinical trials or studies of others and adverse safety events involving the targets of our products may have an adverse impact on our future

commercialization efforts.

From time to time, studies or clinical trials on various aspects of biopharmaceutical products are conducted by academic researchers, competitors or others. The results
of these studies or trials, when published, may have a significant effect on the market for the biopharmaceutical product that is the subject of the study. The publication of
negative results of studies or clinical trials or adverse safety events related to our product candidates, or the therapeutic areas in which our product candidates compete, could
adversely affect our share price and our ability to finance future development of our product candidates, and our business and financial results could be materially and adversely
affected.

As a result of intense competition and technological change in the biotechnical and pharmaceutical industries, the marketplace may not accept our products or

product candidates, and we may not be able to compete successfully against other companies in our industry and achieve profitability.

Many of our competitors have:

·

·

·

drug products that have already been approved or are in development, and operate large, well-funded research and development programs in the biotechnical and
pharmaceutical fields;
substantially  greater  financial,  technical  and  management  resources,  stronger  intellectual  property  positions  and  greater  manufacturing,  marketing  and  sales
capabilities, areas in which we have limited or no experience; and
significantly greater experience than we do in undertaking preclinical testing and clinical trials of new or improved pharmaceutical products and obtaining required
regulatory approvals.

Consequently,  our  competitors  may  obtain  FDA,  Health  Canada  and  other  regulatory  approvals  for  product  candidates  sooner  and  may  be  more  successful  in

manufacturing and marketing their products than we or our collaborators are.

Our  competitors’  existing  and  future  products,  therapies  and  technological  approaches  will  compete  directly  with  the  products  we  seek  to  develop.  Current  and
prospective competing products may be more effective than our existing and future products insofar as they may provide greater therapeutic benefits for a specific problem or
may offer easier delivery or comparable performance at a lower cost.

Any product candidate that we develop and that obtains regulatory approval must then compete for market acceptance and market share. Our products may not gain
market  acceptance  among  physicians,  patients,  healthcare  payers,  insurers,  the  medical  community  and  other  stakeholders.  Further,  any  products  we  develop  may  become
obsolete before we recover any expenses we incurred in connection with the development of these products. As a result, we may never achieve profitability.

We may be unable to obtain patents to protect our technologies from other companies with competitive products, and patents of other companies could prevent us

from manufacturing, developing or marketing our products.

Patent protection

The  patent  positions  of  pharmaceutical  and  biotechnology  companies  are  uncertain  and  involve  complex  legal  and  factual  questions.  The  United  States  Patent  and
Trademark Office and many other patent offices in the world have not established a consistent policy regarding the breadth of claims  that  they  will  allow  in  biotechnology
patents.

9

 
 
 
 
 
 
 
 
 
 
 
 
Our pending patent applications may not result in issued patents and our issued patents may not be held valid and enforceable if challenged. Competitors may be able
to circumvent any such issued patents by adoption of a competitive, though non-infringing product or process. Interpretation and evaluation of pharmaceutical or biotechnology
patent  claims  present  complex  and  often  novel  legal  and  factual  questions.  Our  business  could  be  adversely  affected  by  increased  competition  in  the  event  that  any  patent
granted to it is held to be invalid or unenforceable or is inadequate in scope to protect our operations.

Allowable patentable subject matter and the scope of patent protection obtainable may differ between jurisdictions. If a patent office allows broad claims, the number
and cost of patent interference proceedings in the United States, or analogous proceedings in other jurisdictions and the risk of infringement litigation may increase. If it allows
narrow claims, the risk of infringement may decrease, but the value of our rights under our patents, licenses and patent applications may also decrease.

The scope of the claims in a patent application can be significantly modified during prosecution before the patent is issued. Consequently, we cannot know whether our
pending  applications  will  result  in  the  issuance  of  patents  or,  if  any  patents  are  issued,  whether  they  will  provide  us  with  significant  proprietary  protection  or  will  be
circumvented, invalidated or found to be unenforceable.

Publication of discoveries in scientific or patent literature often lags behind actual discoveries. Patent applications filed in the United States generally will be published
18 months after the filing date unless the applicant certifies that the invention will not be the subject of a foreign patent application. In many other jurisdictions, such as Canada,
patent applications are published 18 months from the priority date. We may not be aware of such literature. Accordingly, we cannot be certain that the named inventors of our
products and processes were the first to invent that product or process or that we were the first to pursue patent coverage for our inventions.

In addition, U.S. patent laws may change which could prevent or limit us from filing patent applications or patent claims in the United States to protect our products
and technologies or limit the exclusivity periods that are available to patent holders for U.S. patents. For example, the Leahy-Smith America Invents Act, (the “ Leahy-Smith
Act”) was signed into law in 2011 and includes a number of significant changes to U.S. patent law. These include changes to transition from a “first-to-invent” system to a “first-
to-file” system and to the way issued patents are challenged. These changes may favour larger and more established companies that have more resources to devote to patent
application filing and prosecution. It is not clear what, if any, impact the Leahy-Smith Act will ultimately have on the cost of prosecuting our patent applications in the United
States, our ability to obtain patents in the United States based on our discoveries and our ability to enforce or defend our U.S. issued patents.

Until such time, if ever, that further patents are issued to us, we will rely upon the law of trade secrets to the extent possible given the publication requirements under
international patent treaty laws and/or requirements under foreign patent laws to protect our technology and our products incorporating the technology. In this regard, we have
adopted certain confidentiality procedures. These include: limiting access to confidential information to certain key personnel; requiring all directors, officers, employees and
consultants  and  others  who  may  have  access  to  our  intellectual  property  to  enter  into  confidentiality  agreements  which  prohibit  the  use  of  or  disclosure  of  confidential
information to third parties; and implementing physical security measures designed to restrict access to such confidential information and products. Our ability to maintain the
confidentiality of our technology is crucial to our ultimate possible commercial success. The procedures adopted by us to protect the confidentiality of our technology may not
be effective, third parties may gain access to our trade secrets or our trade secrets or those of our collaborators may be independently discovered by others. Our collaborators,
employees and consultants and other parties may not comply with the terms of their agreements with us, and we might be unable to adequately enforce our rights or obtain
adequate compensation for the damages caused by unauthorized disclosure or use of our trade secrets or know how. Further, by seeking patent protection in various countries, it
is inevitable that a substantial portion of our technology will become available to our competitors, through publication of such patent applications.

Enforcement of intellectual property rights

Protection  of  the  rights  revealed  in  published  patent  applications  can  be  complex,  costly  and  uncertain.  Our  commercial  success  depends  in  part  on  our  ability  to
maintain and enforce our proprietary rights. If third parties engage in activities that infringe our proprietary rights, our management’s focus will be diverted and we may incur
significant costs in asserting our rights. We may not be successful in asserting our proprietary rights, which could result in our patents being held invalid or a court holding that
the third party is not infringing, either of which would harm our competitive position.

10

 
 
 
 
 
 
 
 
 
Others  may  design  around  our  patented  technology.  We  may  have  to  participate  in  interference  proceedings  declared  by  the  United  States  Patent  and  Trademark
Office, European opposition proceedings, or other analogous proceedings in other parts of the world to determine priority of invention and the validity of patent rights granted or
applied for, which could result in substantial cost and delay, even if the eventual outcome is favourable to us. Our pending patent applications, even if issued, may not be held
valid or enforceable.

We may incur substantial cost in defending our intellectual property.

While we believe  that  our  products  and  technology  do  not  infringe  proprietary  rights  of  others,  third  parties  may  assert  infringement  claims  in  the  future  and  such
claims could be successful. Even if challenges are unsuccessful, we could incur substantial costs in defending ourselves against patent infringement claims brought by others or
in prosecuting suits against others. In addition, others may obtain patents that we would need to license, which may not be available to us on reasonable terms. Whether we are
able to obtain a necessary license would depend on the terms offered, the degree of risk of infringement and the need for the patent.

Our products and product candidates may infringe the intellectual property rights of others, or others may infringe on our intellectual property rights which could

increase our costs.

Our success also depends on avoiding infringement of the proprietary technologies of others. In particular, there may be certain issued patents and patent applications
claiming subject matter which we or our collaborators may be required to license in order to research, develop or commercialize APTO-253 or CG’806. In addition, third parties
may  assert  infringement  or  other  intellectual  property  claims  against  us. An  adverse  outcome  in  these  proceedings  could  subject  us  to  significant  liabilities  to  third-parties,
require disputed rights to be licensed from third-parties or require us to cease or modify our use of the technology. If we are required to license third-party technology, a license
under such patents and patent applications may not be available on acceptable terms or at all. Further, we may incur substantial costs defending ourselves in lawsuits against
charges of patent infringement or other unlawful use of another’s proprietary technology. We may also need to bring claims against others who we believe are infringing our
rights in order to become or remain competitive and successful. Any such claims can be time consuming and expensive to pursue.

If product liability, clinical trial liability or environmental liability claims are brought against us or we are unable to obtain or maintain product liability, clinical

trial or environmental liability insurance, we may incur substantial liabilities that could reduce our financial resources.

The clinical testing and commercial use of pharmaceutical products involves significant exposure to product liability, clinical trial liability, environmental liability and
other risks that are inherent in the testing, manufacturing and marketing of our products. These liabilities, if realized, could have a material adverse effect on the Company’s
business, results of operations and financial condition.

We have obtained limited product liability insurance coverage for our clinical trials on humans; however, our insurance coverage may be insufficient to protect us
against  all  product  liability  damages.  Regardless  of  merit  or  eventual  outcome,  liability  claims  may  result  in  decreased  demand  for  a  future  product,  injury  to  reputation,
withdrawal  of  clinical  trial  volunteers,  loss  of  revenue,  costs  of  litigation,  distraction  of  management  and  substantial  monetary  awards  to  plaintiffs. Additionally,  if  we  are
required to pay a product liability claim, we may not have sufficient financial resources to complete development or commercialization of any of our product candidates and our
business and results of operations will be adversely affected. In general, insurance will not protect us against some of our own actions, such as negligence.

As the Company’s development activities progress towards the commercialization of product candidates, our liability coverage may not be adequate, and the Company
may  not  be  able  to  obtain  adequate  product  liability  insurance  coverage  at  a  reasonable  cost,  if  at  all.  Even  if  the  Company  obtains  product  liability  insurance,  its  financial
position may be materially adversely affected by a product liability claim. A product liability claim could also significantly harm the Company’s reputation and delay market
acceptance of its product candidates. Additionally, product recalls may be issued at the direction of the FDA, other government agencies or other companies having regulatory
control for pharmaceutical sales. If a product recall occurs in the future, such a recall could adversely affect our business, financial condition or reputation.

11

 
 
 
 
 
 
 
 
 
 
We may be unable to obtain partnerships for our product candidates, which could curtail future development and negatively affect our share price. In addition,

our partners might not satisfy their contractual responsibilities or devote sufficient resources to our partnership.

Our strategy for the research, development and commercialization of our products requires entering into various arrangements with corporate collaborators, licensors,
licensees and others, and our commercial success is dependent upon these outside parties performing their respective contractual responsibilities. The amount and timing of
resources  that  such  third  parties  will  devote  to  these  activities  may  not  be  within  our  control.  These  third  parties  may  not  perform  their  obligations  as  expected  and  our
collaborators may not devote adequate resources to our programs. In addition, we could become involved in disputes with our collaborators, which could result in a delay or
termination  of  the  related  development  programs  or  result  in  litigation.  We  intend  to  seek  additional  collaborative  arrangements  to  develop  and  commercialize  some  of  our
products. We may not be able to negotiate collaborative arrangements on favourable terms, or at all, in the future, and our current or future collaborative arrangements may not
be successful.

If we cannot negotiate collaboration, license or partnering agreements, we may never achieve profitability and we may not be able to continue to develop our product
candidates. Continuing Phase Ib, and commencing Phase II and Phase III clinical trials for APTO-253 would require significant amounts of funding and such funding may not

Extensive Government Regulation

Government  regulation  is  a  significant  factor  in  the  development,  production  and  marketing  of  the  Company’s  products.  Research  and  development,  testing,
manufacture, marketing and sales of pharmaceutical products or related products are subject to extensive regulatory oversight, often in multiple jurisdictions, which may cause
significant additional costs and/or delays in bringing products to market, and in turn, may cause significant losses to investors. The regulations applicable to the Company's
product  candidates  may  change.  Even  if  granted,  regulatory  approvals  may  include  significant  limitations  on  the  uses  for  which  products  can  be  marketed  or  may  be
conditioned on the conduct of post-marketing surveillance studies. Failure to comply with applicable regulatory requirements can, among other things, result in warning letters,
the imposition of civil penalties or other monetary payments, delay in approving or refusal to approve a product candidate, suspension or withdrawal of regulatory approval,
product recall or seizure, operating restrictions, interruptions of clinical trials or manufacturing, injunctions or criminal prosecution. In addition, regulatory agencies many not
approve the labeling claims that are necessary or desirable for the successful commercialization of the Company’s product candidates.

Requirements for regulatory approval vary widely from country to country. Whether or not approved in Canada or the United States, regulatory authorities in other
countries must approve a product prior to the commencement of marketing the product in those countries. The time required to obtain any such approval may be longer or
shorter than in Canada or the United States. Approved drugs, as well as their manufacturers, are subject to continuing and ongoing review, and discovery of problems with these
products or the failure to adhere to manufacturing or quality control requirements may result in regulatory restrictions being imposed.

Data security incidents and privacy breaches could result in important remediation costs, increased cyber security costs, litigation and reputational harm.

Cyber security incidents can result from deliberate attacks or unintentional events. Cyber-attacks and security breaches could include unauthorized attempts to access, disable,
improperly modify or degrade the Company’s information, systems and networks, the introduction of computer viruses and other malicious codes and fraudulent “phishing”
emails  that  seek  to  misappropriate  data  and  information  or  install  malware  onto  users’  computers.  Cyber-attacks  in  particular  vary  in  technique  and  sources,  are  persistent,
frequently change and are increasingly more targeted and difficult to detect and prevent against. Our network security and data recovery measures and those of third parties with
which we contract, many not be adequate to protect again cyber-attacks.

Disruptions due to cyber security incidents could adversely affect Aptose’s business. In particular, a cyber security incident could result in the loss or corruption of data from
Aptose’s  research  and  development  activities,  including  clinical  trials,  which  may  cause  significant  delays  to  some  or  all  of  the  Company’s  clinical  programs. Also,  the
Company’s trade secrets, including unpatented know-how, technology and other proprietary information could be disclosed to competitors further to a breach, which would
harm the Company’s business and competitive position. We expect that risks and exposures related to cyber security attacks will remain high for the foreseeable future due to the
rapidly evolving nature and sophistication of these threats. While we have invested in the protection of data and information technology, there can be no assurance that our
efforts to implement adequate security measures would be sufficient to protect the Company against cyber-attacks.

Risks Related to Our Common Shares

Our share price has been and is likely to continue to be volatile and an investment in our Common Shares could suffer a decline in value.

You should consider an investment in our Common Shares as risky and invest only if you can withstand a significant loss and wide fluctuations in the market value of
your investment. The market price of our Common Shares has been highly volatile and is likely to continue to be volatile. This leads to a heightened risk of securities litigation
pertaining to such volatility. Factors affecting our Common Share price include but are not limited to:

·
·
·
·
·
·
·
·
·
·
·
·

our ability to continue as a going concern;
our ability to raise additional capital;
the progress of our pre-clinical and clinical trials;
our ability to obtain partners and collaborators to assist with the future development of our products;
general market conditions;
announcements of technological innovations or new product candidates by us, our collaborators or our competitors;
published reports by securities analysts;
developments in patent or other intellectual property rights;
the cash and investments held by us and our ability to secure future financing;
public concern as to the safety and efficacy of drugs that we and our competitors develop;
shareholder interest in our Common Shares; and
low liquidity in the daily trading volume of our Common Shares.

Future sales of our Common Shares by us or by our existing shareholders could cause our share price to fall.

The issuance of Common Shares by us could result in significant dilution in the equity interest of existing shareholders and adversely affect the market price of our
Common Shares. Sales by existing shareholders of a large number of our Common Shares in the public market and the issuance of Common Shares in connection with strategic
alliances, or the perception that such additional sales could occur, could cause the market price of our Common Shares to decline and have an undesirable impact on our ability
to raise capital.

13

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We are susceptible to stress in the global economy and therefore, our business may be affected by the current and future global financial condition.

If the increased level of volatility and market turmoil that have marked recent years continue, our operations, business, financial condition and the trading price of our
Common Shares could be materially adversely affected. Furthermore, general economic conditions may have a great impact on us, including our ability to raise capital, our
commercialization opportunities and our ability to establish and maintain arrangements with others for research, manufacturing, product development and sales.

An active trading market in our Common Shares may not be sustained.

Our  Common  Shares  are  listed  for  trading  on  the  NASDAQ  Capital  Market  (“NASDAQ”)  and  the  Toronto  Stock  Exchange  (“TSX”).  However,  an  active  trading

market in our Common Shares on the stock exchanges may not be sustained and we may not be able to maintain our listings.

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

We are a corporation existing under the laws of Canada. Some of our directors and officers, and many of the experts named in this Annual Report and the documents
incorporated by reference into this Annual Report, are residents of Canada, and all or a substantial portion of their assets, and a substantial portion of our assets, are located
outside the United States. Consequently, although we have appointed an agent for service of process in the United States, it may be difficult for holders of our Common Shares
who reside in the United States to effect service within the United States upon our directors and officers and experts who are not residents of the United States. It may also be
difficult for holders of our Common Shares who reside in the United States to realize in the United States upon judgments of courts of the United States predicated upon our
civil liability and the civil liability of our directors, officers and experts under the United States federal securities laws. Investors should not assume that Canadian courts (i)
would enforce judgments of United States courts obtained in actions against us or our directors, officers or experts predicated upon the civil liability provisions of the United
States federal securities laws or the securities or “blue sky” laws  of  any  state  within  the  United  States  or  (ii)  would  enforce,  in  original  actions,  liabilities  against  us  or  our
directors, officers or experts predicated upon the United States federal securities laws or any such state securities or “blue sky” laws.

We are likely a “passive foreign investment company” which may have adverse U.S. federal income tax consequences for U.S. shareholders.

U.S. investors in our Common Shares should be aware that the Company believes it was classified as a passive foreign investment company (“PFIC”) during the tax
year ended December 31, 2016 and based on the nature of our business, the projected composition of our gross income and the projected composition and estimated fair market
value of our assets, the Company expects to be a PFIC for the current tax year ending December 31, 2017 and may be a PFIC in subsequent tax years. If the Company is a PFIC
for any year during a U.S. shareholder’s holding period, then such U.S. shareholder generally will be required to treat any gain realized upon a disposition of Common Shares,
or any so-called “excess distribution” received on its Common Shares, as ordinary income, and to pay an interest charge on a portion of such gain or distributions, unless the
shareholder  makes  a  timely  and  effective  “qualified  electing  fund”  election  (“QEF election”)  or  a  “mark-to-market”  election  with  respect  to  the  Common  Shares. A  U.S.
shareholder who makes a QEF election generally must report on a current basis its share of the Company’s net capital gain and ordinary earnings for any year in which the
Company is a PFIC, whether or not the Company distributes any amounts to its shareholders. However, U.S. shareholders should be aware that we do not intend to satisfy
record keeping requirements that apply to a qualified electing fund, and we do not intend to supply U.S. shareholders with information that such U.S. shareholders require to
report under the QEF election rules, in the event that we are a PFIC and a U.S. shareholder wishes to make a QEF election. Thus, U.S. shareholders should assume that they will
not  be  able  to  make  a  QEF  election  with  respect  to  their  Common  Shares. A  U.S.  shareholder  who  makes  the  mark-to-market  election  generally  must  include  as  ordinary
income each year the excess of the fair market value of the Common Shares over the taxpayer’s basis therein. This paragraph is qualified in its entirety by the discussion below
under the heading “Certain United States Federal Income Tax Considerations.” Each U.S. shareholder should consult its own tax advisor regarding the U.S. federal, U.S. local,
and foreign tax consequences of the PFIC rules and the acquisition, ownership, and disposition of our Common Shares.

We are an “emerging growth company,” and we cannot be certain if the reduced reporting requirements applicable to emerging growth companies will make our

common shares less attractive to investors

We are an “emerging growth company,” as defined in the U.S. Jumpstart Our Business Startups Act of 2012, or the JOBS Act. For as long as we continue to be an
emerging  growth  company,  we  may  take  advantage  of  exemptions  from  various  reporting  requirements  that  are  applicable  to  other  public  companies  that  are  not  emerging
growth companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations
regarding  executive  compensation  in  our  periodic  reports  and  exemptions  from  the  requirements  of  holding  a  nonbinding  advisory  vote  on  executive  compensation  and
shareholder approval of any golden parachute payments not previously approved.

We will cease to be an emerging growth company upon the earliest of:

·

·

·

·

the last day of the fiscal year during which we have total annual gross revenues of $1,000,000,000 (as such amount is indexed for inflation every five years by
the SEC or more;

the last day of our fiscal year following the fifth anniversary of the completion of our first sale of common equity securities pursuant to an effective registration
statement under the Securities Act;

the date on which we have, during the previous three-year period, issued more than $1,000,000,000 in non- convertible debt; or

the date on which we are deemed to be a “large accelerated filer”, as defined in Rule 12b–2 of the Exchange Act, which would occur if the market value of our
ordinary shares and ADSs that are held by non-affiliates exceeds $700,000,000 as of the last day of our most recently-completed second fiscal quarter.

We cannot predict if investors will find our common shares less attractive because we may rely on these exemptions. If some investors find our Common Shares less

attractive as a result, there may be a less active trading market for our Common Shares and our share price may be more volatile.

Any failure to maintain an effective system of internal controls may result in material misstatements of our consolidated financial statements or cause us to fail to
meet our reporting obligations or fail to prevent fraud; and in that case, our shareholders could lose confidence in our financial reporting, which would harm our business
and could negatively impact the price of our common shares.

Section 404(a) of the Sarbanes-Oxley Act of 2002, as amended, or SOX, requires that our management assess and report annually on the effectiveness of our internal
controls  over  financial  reporting  and  identify  any  material  weaknesses  in  our  internal  controls  over  financial  reporting. Although  Section  404(b)  of  the  SOX  requires  our
independent registered public accounting firm to issue an annual report that addresses the effectiveness of our internal controls over financial reporting, we have opted to rely on
the exemptions provided to us by virtue of being a foreign private issuer and an emerging growth company, and consequently will not be required to comply with SEC rules that
implement Section 404(b) of SOX until we lose our emerging growth company status.

Effective internal controls are necessary for us to provide reliable financial reports and prevent fraud. If we fail to maintain an effective system of internal controls, we
might not be able to report our financial results accurately or prevent fraud; and in that case, our shareholders could lose confidence in our financial reporting, which would
harm  our  business  and  could  negatively  impact  the  price  of  our  common  shares.  While  we  believe  that  we  have  sufficient  personnel  and  review  procedures  to  allow  us  to
maintain an effective system of internal controls, we cannot assure you that we will not experience potential material weaknesses in our internal control. Even if we conclude
that  our  internal  control  over  financial  reporting  provides  reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  consolidated  financial
statements for external purposes in accordance with IFRS, as issued by the International Accounting Standards Board, because of its inherent limitations, internal control over
financial  reporting  may  not  prevent  or  detect  fraud  or  misstatements.  Failure  to  implement  required  new  or  improved  controls,  or  difficulties  encountered  in  their
implementation, could harm our results of operations or cause us to fail to meet our future reporting obligations.

15

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If we fail to timely achieve and maintain the adequacy of our internal control over financial reporting, we may not be able to produce reliable financial reports or help
prevent fraud. Our failure to achieve and maintain effective internal control over financial reporting could prevent us from complying with our reporting obligations on a timely
basis, which could result in the loss of investor confidence in the reliability of our consolidated financial statements, harm our business and negatively impact the trading price
of our common shares.

As a foreign private issuer, we are not subject to certain United States securities law disclosure requirements that apply to a domestic United States issuer, which

may limit the information which would be publicly available to our shareholders.

As a foreign private issuer, we are exempt from certain rules under the Exchange Act that impose disclosure requirements as well as procedural requirements for proxy
solicitations  under  Section  14  of  the  Exchange Act.  In  addition,  our  officers,  directors  and  principal  shareholders  are  exempt  from  the  reporting  and  “short-swing”  profit
recovery provisions of Section 16 of the Exchange Act. Moreover, we are not required to file periodic reports and financial statements with the SEC as frequently or as promptly
as a company that files as a domestic issuer whose securities are registered under the Exchange Act, nor are we generally required to comply with the SEC’s Regulation FD,
which restricts the selective disclosure of material non-public information. For as long as we are a “foreign private issuer” we intend to file our annual financial statements on
Form 20-F and furnish our quarterly updates on Form 6-K to the SEC for so long as we are subject to the reporting requirements of Section 13(g) or 15(d) of the Exchange Act.
However, the information we file or furnish is not the same as the information that is required in annual and quarterly reports on Form 10-K or Form 10-Q for U.S. domestic
issuers. Accordingly, there may be less information publicly available concerning us than there is for a company that files as a domestic issuer.

History and Development of the Company.

Old  Lorus  was  incorporated  under  the Business  Corporations  Act (Ontario)  on  September  5,  1986  under  the  name  RML  Medical  Laboratories  Inc.  On  October  28,
1991, RML Medical Laboratories Inc. amalgamated with Mint Gold Resources Ltd., resulting in Old Lorus becoming a reporting issuer (as defined under applicable securities
law)  in  Ontario,  on  such  date.  On August  25,  1992,  Old  Lorus  changed  its  name  to  IMUTEC  Corporation.  On  November  27,  1996,  Old  Lorus  changed  its  name  to  Imutec
Pharma  Inc.,  and  on  November  19,  1998,  Old  Lorus  changed  its  name  to  Lorus  Therapeutics  Inc.  On  October  1,  2005,  Old  Lorus  continued  under  the Canada  Business
Corporations Act.

On  the Arrangement  Date,  Old  Lorus  completed  a  plan  of  arrangement  and  corporate  reorganization  with,  among  others,  6650309  Canada  Inc.  (“New  Lorus”),
6707157 Canada Inc. and Pinnacle International Lands, Inc. As a result of the plan of arrangement and reorganization, each Common Share of Old Lorus was exchanged for
one Common Share of New Lorus. New Lorus continued the business of Old Lorus after the Arrangement Date with the same officers and employees and continued to be
governed by the same board of directors as Old Lorus prior to the Arrangement Date.

On August 28, 2014, New Lorus changed its name from Lorus Therapeutics Inc. to Aptose Biosciences Inc. and on October 1, 2014 we consolidated our outstanding

Common Shares on the basis of one post-consolidation Common Share for each twelve pre-consolidation Common Shares.

The address of the Company’s head and registered office is 5955 Airport Road Suite #228, Mississauga, Ontario, Canada, L4V 1R9 and our phone number is (647)

Aptose  has  three  subsidiaries: Aptose  Biosciences  U.S.  Inc.  (“Aptose  USA”),  a  company  incorporated  under  the  laws  of  Delaware,  USA, Aptose  Suisse  GmbH
(“Aptose Suisse”)  a  company  incorporated  under  the  laws  of  Zug,  Switzerland  and  NuChem  Pharmaceuticals  Inc.  (“NuChem”),  a  company  incorporated  under  the  laws  of
Ontario, Canada. Aptose owns 100% of the issued and outstanding voting share capital of Aptose USA and Aptose Suisse and 80% of the issued and outstanding voting share
capital of NuChem.

Our Common Shares are listed on the NASDAQ under the symbol “APTO” and on the TSX under the symbol “APS”.

Aptose Biosciences is a science-driven biotechnology company advancing highly differentiated agents to treat unmet medical needs in life-threatening cancers, such as
acute myeloid leukemia (AML), high-risk myelodysplastic syndromes (MDS) and other hematologic malignancies. Based on insights into the genetic and epigenetic profiles of
certain cancers and patient populations, Aptose is building a pipeline of novel and targeted oncology therapies directed at dysregulated processes and signaling pathways in
cancer cells, and this strategy is intended to optimize efficacy and quality of life by minimizing the cytotoxic side effects associated with conventional therapies. Our product
pipeline includes cancer drug candidates that exert potent activity as stand-alone agents and that enhance the activities of other anticancer agents without causing overlapping
toxicities. Indeed, we believe our targeted products can emerge as first-in-class or best-in-class agents that deliver single agent benefit and may serve as part of a combination
therapeutic strategy for specific populations of cancer patients.

We  believe  the  future  of  cancer  treatment  and  management  lies  in  the  prospective  selection  and  treatment  of  patients  having  malignancies  that  are  genetically  or
epigenetically predisposed to response based on a drug’s unique mechanism of action. We are of the view that many drugs currently approved for the treatment and management
of cancer are not selective for the specific genetic alterations (targets) that cause the patient’s tumor and hence lead to significant toxicities due to off-target effects. Aptose’s
strategy is to develop agents that target underlying disease-promoting mutations or altered pathways within a patient population, and we intend to apply this strategy across
several therapeutic indications in oncology, including hematologic malignancies and solid tumor indications.

Aptose Biosciences has two preclinical/clinical-stage programs, and a third program that is discovery-stage and positioned for partnering. Aptose’s pan-FLT3 / BTK
program, CG’806, is currently in preclinical development and moving toward IND submission, with anticipation of commencing a Phase 1 trial the first half of 2018. APTO-253
is Aptose’s second program and at the Phase 1b clinical stage for the treatment of patients with relapsed / refractory blood cancers, including AML and high-risk MDS under an
IND allowed by the U.S. FDA to evaluate APTO-253 as a therapeutic agent dosed on a weekly administration schedule for the treatment of certain hematologic malignancies.
The APTO-253 program is currently on clinical hold while attempts are made to manufacture a newly formulated and stable clinical supply.

17

 
 
 
 
 
 
The following table sets forth various product conditions in our pipeline and their respective stages of development.

CG026806 (CG’806) is a highly potent first-in-class pan-FLT3/BTK inhibitor. This small molecule therapeutic agent, exhibits a picomolar IC50 toward the FMS-like
tyrosine kinase 3 with the Internal Tandem Duplication (FLT3-ITD) and significant potency against other mutant forms of FLT3. Because of the potency of CG’806 against the
FLT3 enzyme, it may become an effective therapy for AML patients, including the subset of patients having the FLT3-ITD, which occurs in approximately 30% of patients
with AML and is associated with poor prognosis. Importantly, CG’806 targets other oncogenic kinases which may also be operative in AML, thereby potentially allowing the
agent to become an important therapeutic option for a difficult-to-treat patient population.

In addition to potent inhibition of wild type and mutant forms of the FLT3 enzyme, CG’806 is a highly potent, reversible, non-covalent inhibitor of the wild type and
mutant forms of the BTK enzymes. Overexpression of BTK drives certain B cell malignancies, including chronic lymphocytic leukemia (CLL), mantle cell lymphoma (MCL),
diffuse large B cell lymphoma (DLBCL) and others. Treatment of such B cell malignancies with covalent BTK inhibitors that target the cysteine residue in the active site of
BTK can lead to drug resistance via mutation of the cysteine amino acid residue to a serine residue (BTK-C481S mutant). CG’806 targets the ATP-binding pocket of BTK
through a reversible, non-covalent mechanism, thereby allowing CG’806 to retain low nM potency against the BTK-C481S mutant enzyme. Thus, CG’806 may serve as a novel
therapeutic agent to treat B cell malignancy patients that are refractory, resistant or intolerant to covalent BTK inhibitors.

In  June  2016,  we  announced  an  exclusive  global  option  and  license  agreement  focused  on  the  development  of  CG’806  of  up  to  US$303  million,  inclusive  of

development, regulatory and commercial-based milestones.

APTO-253,  the  Company’s  second  program,  is  a  small  molecule  therapeutic  agent  that  inhibits  expression  of  the  c-Myc  oncogene  without  causing  general
myelosuppression of the healthy bone marrow. The c-Myc oncogene is overexpressed in hematologic cancers, including AML. C-Myc is a transcription factor that regulates cell
growth, proliferation, differentiation and apoptosis, and overexpression amplifies new sets of genes to promote oncogenesis. APTO-253 dramatically down-regulates expression
of the c-Myc oncogene in AML cells and depletes those cells of the c-Myc oncoprotein, leading to apoptotic cell death in AML cells. Thus APTO-253 may serve as safe and
effective c-Myc inhibitor for AML that combines well with other agents and does not impact the normal bone marrow.

18

 
 
 
 
 
 
In  November  2015, Aptose’s  phase  1b  trial  of APTO-253  in  patients  with AML  was  placed  on  clinical  hold.  Since  that  time,  the  Company  has  actively  evaluated
multiple  formulation  and  production  methodologies  with  the  goal  of  developing  a  superior  IV  formulation.  In  January  2017,  we  have  announced  that  after  successfully
manufacturing  multiple  non-cGMP  batches  of  a  new  drug  product  formulation  for APTO-253,  including  a  batch  that  has  been  stable  and  soluble  for  over  six  months,  the
Company  encountered  an  additional  manufacturing  setback  which  further  delayed  the  return  of APTO-253  to  the  clinic.  While Aptose  has  made  significant  advances  in
understanding the novel c-Myc inhibitory mechanism of APTO-253, additional time will be required to define the cause of the cGMP manufacturing delay and to potentially
restore APTO-253 to a state it can be developed clinically and partnered. Further, we announced that we would prioritize our resources toward the development of CG’806 and
temporarily delay clinical activities with APTO-253.

Aptose’s  leadership  team  comprises  accomplished  industry,  financial  and  clinical  research  professionals  who  are  dedicated  to  building  a  comprehensive  anticancer
drug  pipeline  and  clinical  development  programs  focused  on  targeted  therapeutics  directed  against  dysregulated  oncogenic  processes  in  patients  with  life-threatening
hematologic malignancies.

B.

Business overview.

As  noted  above,  Aptose  is  committed  to  the  development  of  anticancer  drugs  that  target  aberrant  oncologic  signaling  that  underlie  a  particular  life-threatening
malignancy. This targeted approach is intended to impact the disease-causing events in cancer cells without affecting normal processes within cells. Such an approach requires
that we first identify critical underlying oncogenic mechanisms in cancer cells and then develop a therapeutic that selectively impacts such oncogenic mechanisms. As a multi-
kinase  pan-FLT3  /  BTK  inhibitor,  CG’806  targets  multiple  critical  pathways  that  overlap  to  lead  to  the  proliferation  of  cancer  cells,  including  the  B-cell  receptor  signaling
pathway and FLT3 receptor pathways that converge at various points in the signaling cascade. Further, Aptose created the APTO-253 small molecule targeted drug that inhibits
expression of the c-Myc oncogene and is under development as a novel therapy for AML and the related MDS.

CG’806

In June 2016, Aptose entered into a definitive agreement with South Korean company, CrystalGenomics, Inc. (CG), granting Aptose an exclusive option to research, develop
and commercialize CG026806 (CG’806) in all countries of the world except Korea and China, for all fields of use. CG’806 is a highly potent, non-covalent small molecule
therapeutic  agent,  exhibiting  a  picomolar  IC50  toward  the  FMS-like  tyrosine  kinase  3  with  the  Internal  Tandem  Duplication  (FLT3-ITD  and  single-digit  nanomolar  IC50’s
against  Bruton’s  tyrosine  kinase  (BTK)  and  its  C481S  mutant  (BTK-C481S)).  Further,  CG’806  is  a  multi-targeted  BTK  /  FLT3-ITD  inhibitor  as  it  impacts  other  relevant
oncogenic targets, including the Aurora kinases (AURK), RET, MET, DDR2, and SRC kinases.

As a potent inhibitor of FLT3-ITD and other mutant forms of FLT3, CG’806 may become an effective therapy in this subset of acute myeloid leukemia (AML) patients. FLT3-
ITD  occurs  in  approximately  30%  of  patients  with AML.  Importantly,  CG’806  targets  other  oncogenic  kinases  which  may  also  be  operative  in  FLT3-ITD AML,  thereby
potentially allowing the agent to become an important therapeutic option for a difficult-to-treat patient population.

The C481S mutation of BTK arises from therapy with covalent, irreversible BTK inhibitors that target the active site cysteine residue of BTK, thereby conferring resistance to
other  covalent  BTK  inhibitors. As  a  non-covalent,  reversible  inhibitor,  CG’806  does  not  rely  on  the  cysteine  481  residue  (Cys481)  for  binding  in  the  active  site  of  BTK.
Consequently, patients relapsed or refractory to other commercially approved or development stage BTK inhibitors with chronic lymphocytic leukemia (CLL) or mantle cell
lymphoma (MCL) may continue to be sensitive to CG’806 therapy.

19

 
 
 
 
 
 
 
 
 
 
 
Role of BTK in B-cell signaling

BTK, a member of the TEC family kinase, is an essential element of B-cell receptor (BCR) signaling, which is required for B-cell maturation, survival and proliferation. It is an
upstream activator of multiple pro-survival / anti-apoptotic pathways, including the NF-KB, mTOR-AKT and ERK pathways. BTK is overexpressed in malignant cells from
patients with various B-cell malignancies, such as CLL, MCL, AML, and diffuse large b-cell lymphoma (DLBCL). Disruption of BCR signaling via inhibition of BTK, has
been shown to lead to clinical remissions in these patients.

CG’806 as a Non-covalent, Reversible Kinase Inhibitor

Binding  studies  of  CG’806  have  confirmed  non-covalent,  reversible  inhibition  of  BTK,  FLT3-ITD  and Aurora  Kinase A.  Commercially-approved,  covalent  BTK  inhibitors
possess a Michael acceptor to react with Cys481 in BTK and irreversibly inactivate the BTK enzyme. In contrast, CG’806 does not require reactivity with the Cys481 residue
for inhibition of the BTK enzyme, thereby allowing CG’806 to inhibit the wild type and Cys481 mutant form of the BTK enzyme.

Preclinical In Vitro Evaluation of CG’806

CG’806 is a potent inhibitor of BTK and FLT3 wild types, as well as the BTK C481S and FLT3-ITD mutants, which represent major sources of therapy relapse or are negative
prognostic signals in patients. In enzymatic assays, CG’806 has demonstrated best-in class potency against the BTK C481S mutant with an IC50 of 2.5 nM. CG’806 also has
potent  activity  against  the  FLT-ITD  mutation,  occurring  in  30-35%  of AML  patients,  with  an  IC50  against  the  purified  enzyme  of  0.8  nM  (800pM).  Similarly,  CG’806
demonstrated picomolar potency against Aurora A (IC50 0.4 nM). Notably, CG’806 is a potent inhibitor of interleukin-2-inducible T-cell kinase (ITK), at approximately 4 nM.
ITK is speculated to play a role in suppressing activated T-cell function, hence inhibition of ITK alleviates this suppression, and provide for a potential immunomodulatory
anti-tumor  mechanism.  Finally,  CG’806  does  not  exhibit  any  inhibition  of  EGFR.  EGFR  inhibition  has  been  speculated  to  contribute  to  the  toxicity  observed  from  the
commercially approved BTK inhibitor.

BTK is overexpressed in the blast cells of approximately 80% of AML patients as compared to normal PBMCs in healthy subjects. Researchers have shown that BTK inhibition
attenuates the proliferation and survival of FLT3-ITD primary AML blasts and AML cell lines, as well as inhibits the downstream activation FLT3-ITD-dependent Myc and
STAT5 kinases. CG’806 is the only drug in development that inhibits both FLT3-ITD and BTK pathways reported to synergize to drive the proliferation and survival of AML.

CG’806 Xenograft Studies

In vivo subcutaneous AML tumor models of anti-cancer efficacy revealed CG’806 induced rapid and sustained tumor eradication (Figure 1). CG’806 was administered orally
once  daily,  for  14  days.  Moreover,  CG’806  exhibited  the  sustained  tumor  elimination  post  therapy,  while  demonstrating  no  impact  to  murine  body  weight,  no  impacts  to
hematology cell counts or visible organ toxicities – necropsy and clinical pathology findings did not reveal any abnormal observations. A maximum tolerated dose has not yet
been identified with murine xenograft studies, having been performed up to 450 mg/kg orally for 14 days (CrystalGenomics preliminary toxicity data).

Figure 1. Efficacy of CG’806 in MV4-11 xenograft model.

MV4-11 tumor bearing mice were administered an oral suspension once daily for 14 days of CG’806 at 2 mg/kg (blue line), 10 mg/kg (green line) or 100 mg/kg (red line),
Ibrutinib, 12 mg/kg (turquoise line), or vehicle (Control; black line) with 7-day post-treatment follow-up. Tumor volumes and body weights were measured 3 times weekly.

CG’806 Intellectual Property

A PCT application providing composition of matter and use protection for CG’806 was filed in late-2013, with a potential expiry in 2033 before extension opportunities, across
all major geographies.

CG’806 Status

CG’806 is currently in IND-enabling studies and Aptose expects to file an IND for a first-in-human clinical trial by late-2017. CG’806 is being developed as a once-daily, oral
therapeutic.

APTO-253

APTO-253 is a novel small molecule that inhibits expression of the c-Myc oncogene, leading to cell cycle arrest and programmed cell death (apoptosis) in human-
derived solid tumor and hematologic cancer cells. Likewise, in nonclinical pharmacology studies APTO-253 demonstrates in vivo anti-tumor activity against xenograft models
of  solid  tumors  and  hematologic  cancers,  with  acute  myeloid  leukemia  (AML)  cells  exhibiting  a  particular  sensitivity  to APTO-253. A  Phase  1  study  with APTO-253  was
completed and demonstrated modest clinical activity in patients with advanced solid tumors, and APTO-253 is currently under evaluation in a Phase 1b trial in patients with
acute  leukemias  (including AML)  and  high-risk  MDS.  The  original  formulation  of APTO-253  led  to  filter-clogging  in  the  Phase  1b  trial,  and  since  that  time Aptose  has
developed an improved formulation speculated to avoid such events moving forward. Further, manufacturing delays of a clinical supply with the new drug product formulation
led to delays in the Phase 1b clinical trial, and Aptose is now performing studies to determine the root cause and corrective action of the manufacturing delay. It is possible that
these issues can be resolved during the second half of 2017 such that the clinical supply of APTO-253 can be manufactured with confidence and the program can be positioned
for a return to the clinical trial and/or partnering.

Acute Myeloid Leukemia

AML is a rapidly progressing cancer of the blood and bone marrow characterized by the uncontrolled proliferation of dysfunctional myeloblasts that do not mature into
healthy blood cells. It is the most common form of acute leukemia in adults. The American Cancer Society estimates there will be approximately 19,950 new cases of AML and
approximately  10,430  deaths  from AML  in  the  U.S.  in  2016.  Standard  induction  therapy  with  chemotherapy  is  successful  in  many AML  patients,  but  the  majority  of  these
patients will relapse with treatment refractory disease. The average age of a patient with AML is 67 years.  Approximately 48% patients less than age 60, and 34% of patients
greater than or equal to age 60, with residual disease after induction therapy will achieve a remission, as reported by Datamonitor.

Myelodysplastic Syndromes

MDS  are  a  group  of  blood  and  bone  marrow  disorders.  In  MDS,  stem  cells  do  not  mature  normally,  and  the  number  of  blasts  (immature  cells)  and  dysplastic
(abnormally developed) cells increases. Also, the number of healthy mature cells decreases, meaning there are fewer normal red blood cells, white blood cells, and platelets. The
numbers of blood cells are often called blood cell counts. Because of the decrease in healthy cells, people with MDS often have anemia (a lowered blood cell count), and may
have neutropenia (a low white blood cell count) and thrombocytopenia (a low platelet count). Also, the chromosomes (long strands of genes) in the bone marrow cells may be
abnormal. According to the American Cancer Society, there are approximately 13,000 new cases of MDS annually in the US. Additionally, Datamonitor Healthcare reports
median survival in higher risk MDS patients may range between five months and two years. There are several subtypes of MDS, and some subtypes of MDS may eventually
turn into AML.

Solid Tumors

Phase  I  data  with APTO-253  in  patients  with  solid  tumors  and  preclinical  data  in  solid  tumor  cells,  including  non-small  cell  lung  cancer  (“NSCLC”),  identified  an
opportunity for APTO-253 in patients possessing cancers with reduced Klf4 Gene expression. Our prior Phase 1 study with APTO-253 also revealed a favorable safety profile
for APTO-253. Various solid tumors have exhibited suppressed levels of Klf4 Gene in scientific publications, including colorectal, gastric, pancreatic, prostate and cervical
cancers, as well as NSCLC. NSCLC is an indication that we consider to have a large market potential and important unmet need worldwide, in which the Klf4 Gene is a tumor
suppressor that is present in case-matched normal cells but depressed in NSCLC tumor cells. Aptose may in the future evaluate the clinical utility of APTO-253 in additional
studies in a subset of NSCLC patients that may be predisposed to a response with a therapeutically activating the Klf4 Gene.

In January 2011, Aptose announced the first patient enrolment in a Phase I dose-escalation study for APTO-253 in patients with advanced or metastatic solid tumors
who are unresponsive to conventional therapy or for which no effective therapy is available. The study was initially being conducted at Memorial Sloan-Kettering Cancer Center
in New York and later added MD Anderson Cancer Center in Houston as a second site. Objectives of the study included determination or characterization of the safety profile,
maximum tolerated dose, and antitumor activity of APTO-253, as well as pharmacokinetics and a recommended Phase II dose for subsequent clinical trials.

In June 2012, Aptose announced the addition of MD Anderson Cancer Center as a second site in the then ongoing APTO-253 Phase I clinical trial, under the direction
of Dr. Jennifer Wheler as the principal investigator. In addition, Aptose announced that the study had successfully completed the accelerated drug dose escalation stage (Stage
1), with further escalation under way in the non-accelerated dose escalation stage (Stage 2) for the purpose of determining the maximal tolerated dose level and recommended
Phase II dose. The addition of a second site expanded patient availability for enrollment.

22

 
 
 
 
 
 
 
 
 
In  January  2013, Aptose  announced  that  Phase  I  clinical  study  of APTO-253  has  successfully  escalated  to  the  target  dose  level  based  on  predicted  and  observed
clinical effects without limitation by toxicity. The success of this study allowed Aptose to initiate a biomarker clinical investigation to further explore the effects of the drug at
relevant doses determined in the clinical trial.

In April 2013, Aptose announced the presentation of preclinical data at the 2013 Annual Meeting of the American Association for Cancer Research (“AACR”), held
in Washington, DC from April 6, 2013 through April 10, 2013. The poster presentation titled “Utilization of KLF4 as a pharmacodynamic biomarker for in vivo anticancer
activity of a novel small molecule drug APTO-253” covered data from preclinical studies on anticancer activity and tumor biomarker analysis for APTO-253 in animal models
of human NSCLC. The studies demonstrate that APTO-253 has antitumor activity with a dose-response effect in NSCLC that is associated with a dose dependent increase of
the KLF4 gene.

In July 2013, Aptose announced the results of the Phase 1 clinical trial of APTO-253. In this first-in-man, dose-escalation clinical study, APTO-253 demonstrated a
favorable safety profile, as well as encouraging signs of antitumor activity. The design of this trial consisted of APTO-253 as a single agent in patients with advanced solid
tumors resistant to multiple standard therapies. The study enrolled 27 patients, all of which had failed a median of four prior chemotherapies. Although this was primarily a
dose-escalation safety study, efficacy and pharmacokinetics were also explored.

The clinical trial enrolled patients at seven dose levels ranging from 20 to 229 mg/m2. Of the 27 patients enrolled, 17 were evaluable for efficacy. Of these 17 patients,
seven (41%) achieved stable disease by Response Evaluation Criteria In Solid Tumors (“RECIST”). This included patients with colorectal, lung, appendiceal, liver and uterine
cancers. Dose related activity was demonstrated at the higher dose levels (176 and 229 mg/m2). At these two highest dose levels, four of five evaluable patients (80%) achieved
sustained stable disease by RECIST ranging from 5.6 months to 8 months, representative of disease control. Of these, a patient with non-small cell lung cancer at the highest
dose level additionally demonstrated non-index tumor shrinkage.

The  safety  assessment  indicated  that APTO-253  was  well  tolerated  at  all  dose  levels  tested  in  this  trial.  The  dose  escalation  was  not  limited  by  toxicity.  The  most
common  adverse  event  was  Grade  1  or  2  fatigue  seen  in  three  patients.  There  was  one  Grade  3  toxicity,  asymptomatic  low  blood  phosphate  level  that  was  reversible  by
supplementation with phosphates. The pharmacokinetic profile was consistent with the predictive profile seen preclinically, and the elimination profile and half-life in patients
were suggestive of a very rapid distribution phase and prolonged retention.

Multi-Targeting Bromodomain Program

In November 2015, Aptose entered into a definitive agreement with Moffitt Cancer Center for exclusive global rights to potent, multi-targeting, single-agent inhibitors
for  the  treatment  of  hematologic  and  solid  tumor  cancers.  These  small  molecule  agents  are  inhibitors  of  the  Bromodomain  and  Extra-Terminal  motif  (BET)  protein  family
members,  which  simultaneously  target  specific  kinase  enzymes.  The  molecules  developed  by  Moffitt  exhibited  potency  against  the  BET  family  members  and  specific
oncogenic kinases which, when inhibited, are synergistic with BET inhibition. Under the agreement, Aptose would gain access to the drug candidates developed by Moffitt and
the underlying intellectual property covering the chemical modifications enabling potent bromodomain (BRD) inhibition on the chemical backbone of a kinase inhibitor.

In January 2017, Aptose terminated the collaboration with Moffitt Cancer Center for the development of the dual BRD4 / JAK2 inhibitor program.

23

 
 
 
 
 
 
 
 
 
Multi-Targeting Epigenetic Program

In November 2015, Aptose also announced an exclusive drug discovery partnership with Laxai Avanti Life Sciences (LALS) for their expertise in next generation
epigenetic-based therapies. Under the agreement, LALS will be responsible for developing multiple clinical candidates, including optimizing candidates that exert dual BRD4 /
kinase inhibitory activity. Based on available resources, Aptose halted further investment in the collaboration with LALS in late 2016. However, the program delivered novel IP
and hit molecules for further optimization. As a consequence, Aptose may choose to out-license the program.

Discontinued Programs

In January 2016, Aptose provided notification of termination to Genentech for the intellectual property for IL-17E, and will cease further development activities for

APTO-500 (MELK inhibitor), as the programs fall outside of the scope of Aptose’s pipeline and vision.

BUSINESS OF THE COMPANY

NASDAQ listing

On October 21, 2014, Aptose announced that its Common Shares were approved for listing on NASDAQ under the symbol “APTO” and began trading on NASDAQ

on October 23, 2014. Aptose has retained its listing on the TSX under the symbol “APS”.

24

 
 
 
 
 
 
 
 
 
 
 
 
 
Reverse Stock Split

On  October  1,  2014, Aptose  filed  articles  of  amendment  to  give  effect  to  the  reverse  stock  split  (consolidation)  of  its  Common  Shares  on  the  basis  of  one  post-
consolidation Common Share for each 12 pre-consolidation Common Shares (the “Reverse Stock Split”). The number of Common Shares outstanding as of the time of the
announcement was 139,324,451. The number of Common Shares outstanding immediately following the Reverse Stock Split was 11,610,402.

Name and year end change

On September 2, 2014, we announced that we had changed our name to Aptose Biosciences Inc. from the previous name of Lorus Therapeutics Inc. The new name
reflects our new focus and clinical-stage pipeline strategy, as an oncology research and development organization advancing new therapeutics and molecular diagnostics based
on insights into the genetic profiles of certain cancers and patient populations.  Our lead product candidate APTO-253 exerts its antitumor effects by activating a key apoptotic
pathway in tumor cells. The term "apoptosis" represents the innate self-killing capacity of cells triggered upon the onset of cellular damage, and cancer cells employ various
mechanisms to avoid apoptosis. For these reasons, "apoptosis" is the intuitive root of the name of "Aptose Biosciences." In addition, our stated goal with respect to the name
change is to align the product portfolio and product development with the strategic course set by its new management team.

Effective July 17, 2014, we changed our fiscal year end from May 31 to December 31. As a result of that change the reference period for 2014 is for the seven months
ended December 31, 2014 while the following periods are for the twelve months ended December 31, 2016 and 2015, respectively, and therefore not directly comparable to the
seven month period.

Changes in Management

On October 28, 2013, William G. Rice, Ph.D., was appointed as Chief Executive Officer and Chairman of the Board while Dr. Aiping Young continued as President
and  Chief  Operating  Officer  of  the  Company  until  she  departed  the  Company  on  March  18,  2014. Aptose  also  appointed  Daniel  D.  Von  Hoff,  M.D.,  to  serve  as  a  special
advisor to fulfill the functions of the Company’s Senior Vice President of Medical Affairs. Dr. Von Hoff is an independent contractor and advisor but is not an employee of
Aptose. The Board, after receiving the recommendation of a special committee composed of independent directors formed in September 2013 to review strategic alternatives
available to the Company, designed to secure the long-term financial and operational sustainability of the Company with a view to enhance shareholder value, unanimously
approved the appointments. In doing so, the Board determined that such appointments were in the best interest of Aptose, as they were considered to enhance the management
team and advisory team with the addition of two seasoned and experienced biotechnology executives bringing extensive clinical development and capital raising experience and
improving the awareness and presence of the Company in the United States. On April 10, 2014, Dr. Rice was additionally appointed as President of the Company.

On October 29, 2013, Brian Druker, M.D., was appointed as the Chair of the Company’s Scientific Advisory Board. Like Dr. Von Hoff, Dr. Druker is an independent

contractor and advisor but not an employee of Aptose.

On December 2, 2013, Avanish Vellanki was appointed as Chief Business Officer of the Company, to manage global business development, licensing and corporate
strategy, and Gregory K. Chow was appointed as Chief Financial Officer, with responsibility for corporate finance and accounting functions for the Company. On April 10,
2014, Messrs. Vellanki and Chow were additionally appointed as Senior Vice Presidents of the Company.

On September 8, 2014, Stephen B. Howell was appointed Chief Medical Officer of the Company.

Mr. Vellanki resigned from Aptose Biosciences Inc. effective March 24, 2017.

Financial Strategy

To  meet  our  future  financing  requirements,  we  intend  to  finance  our  operations  through  some  or  all  of  the  following  methods:  public  or  private  equity  financings,

collaborative and licensing agreements. We intend to pursue financing opportunities as they arise. See “Item 3. Key Information—D. Risk Factors” above.

At-The-Market (“ATM”) Facility

On April 2, 2015, we entered into an ATM equity facility with Cowen and Company, LLC, acting as sole agent. Under the terms of this facility, we may, from time to
time,  sell  shares  of  our  common  stock  having  an  aggregate  offering  value  of  up  to  US$20  million  through  Cowen  and  Company,  LLC  on  the  Nasdaq  Capital  Market.  We
determine, at our sole discretion, the timing and number of shares to be sold under this ATM facility. During the twelve months ended December 31, 2016, the Company issued
3,673,933Common Shares under the ATM at a price of US$1.65 per share for gross proceeds of approximately Cdn $7.97 million.

April 2014 Public Offering

In April  2014,  we  completed  a  public  offering  in  Canada  and  a  simultaneous  private  placement  in  the  United  States  of  Common  Shares. Aptose  issued  4,708,334
(56,500,000  pre-consolidation)  Common  Shares  at  a  purchase  price  of  $6.00  ($0.50  pre-consolidation)  per  Common  Share  including  541,667  (6,500,000  pre-consolidation)
Common Shares pursuant to the partial exercise of an over-allotment option, for aggregate gross proceeds of $28,250,000. The total costs associated with the transaction were
approximately $2,665,914 which includes a cash commission of $1,977,500 based on 7% of the gross proceeds received as part of the offering.

December 2013 Public Offering

In  December  2013, Aptose  completed  a  public  offering  of  Common  Shares. Aptose  issued  1,060,833  (pre-consolidation  12,730,000)  common  shares  at  a  price  of
$6.60 (pre-consolidation $0.55) per common share and an additional 159,125 (pre-consolidation 1,909,500) common shares upon the exercise of the overallotment option for
aggregate gross proceeds of $8.1 million.

The total costs associated with the transaction were approximately $1.1 million which include a cash commission of $483 thousand based on 6% of the gross proceeds
received as part of the offering, and the issuance of 73,198 (pre-consolidation 878,370) broker warrants with an estimated fair value of $350 thousand. The fair value of these
warrants was determined using the Black Scholes model with a 24 month time to maturity, an assumed volatility of 130% and a risk free interest rate of 1.5%. Each broker
warrant  was  exercisable  into  one  common  share  of  the  Company  at  a  price  of  $6.60  (pre-consolidation  $0.55)  for  a  period  of  twenty  four  months  following  closing  of  the
offering.

June 2013 Promissory Notes and Warrants

In June 2013, we completed a private placement of units at a price of $1,000 per unit, for aggregate gross proceeds of $918,000. Each unit consisted of (i) a $1,000
principal  amount  of  unsecured  promissory  note  and  (ii)  1,000  Common  Share  purchase  warrants.  The  promissory  notes  bore  interest  at  a  rate  of  10%  per  annum,  payable
monthly and were due June 19, 2014. Each warrant entitled the  holder  to  purchase  one  Common  Share  of Aptose  at  a  price  per  Common  Share  equal  to  $3.00  ($0.25  pre-
consolidation) at any time until June 19, 2015. These notes and any interest accrued thereon were repaid in full in April 2014.

Agreements

Manufacturing Agreements

We  currently  rely  upon  subcontractors  for  the  manufacture  of  our  drug  candidates.  The  subcontractors  manufacture  clinical  material  according  to  current  Good
Manufacturing Practices, or GMPs, at contract manufacturing organizations that have been approved by our quality assurance department staff, after having conducted audits to
ensure such manufacturers meet the requirements of the relative regulatory authorities.

Manufactured product for clinical purposes is tested for conformance with product specifications prior to release by our quality assurance staff. GMP batches of our

drug candidates are subjected to prospectively designed stability test protocols.

License Agreements

CrystalGenomics

In June 2016, Aptose entered into a definitive agreement with South Korean company, CrystalGenomics, Inc. (CG), granting Aptose an exclusive option to research,
develop  and  commercialize  CG026806  (CG’806)  in  all  countries  of  the  world  except  Korea  and  China,  for  all  fields  of  use.  CG’806  is  a  highly  potent,  non-covalent  small
molecule therapeutic agent, exhibiting single-digit nanomolar IC50’s against Bruton’s tyrosine kinase (BTK) and its C481S mutant (BTK-C481S) and a picomolar IC50 toward
the FMS-like tyrosine kinase 3 with the Internal Tandem Duplication (FLT3-ITD).

Moffitt Cancer Center

In November 2015, Aptose entered into a definitive agreement with Moffitt Cancer Center for exclusive global rights to potent, multi-targeting, single-agent inhibitors
for  the  treatment  of  hematologic  and  solid  tumor  cancers.  Under  the  agreement, Aptose  will  gain  access  to  the  drug  candidates  developed  by  Moffitt  and  the  underlying
intellectual  property  covering  the  chemical  modifications  enabling  potent  bromodomain  (BRD)  inhibition  on  the  chemical  backbone  of  a  kinase  inhibitor.  In  January  2017,
Aptose terminated the collaboration with Moffitt Cancer Center and halted further investment into the program.

Laxai Avanti Life Sciences (LALS)

In November 2015, Aptose also announced an exclusive drug discovery partnership with Laxai Avanti Life Sciences (LALS) for their expertise in next generation
epigenetic-based  therapies.  Under  the  agreement,  LALS  would  be  responsible  for  developing  multiple  clinical  candidates,  including  optimizing  candidates  derived  from
Aptose's relationship with the Moffitt Cancer Center. Aptose will own global rights to all newly discovered candidates characterized and optimized under the collaboration,
including all generated intellectual property. Aptose halted further efforts with LALS in late 2016.

Other

From  time  to  time,  we  enter  into  other  research  and  technology  agreements  with  third  parties  under  which  research  is  conducted  and  monies  expended.  These

agreements outline the responsibilities of each participant and the appropriate arrangements in the event the research produces a product candidate.

Intellectual Property and Protection of Confidential Information and Technology

We  believe  that  our  issued  patents  and  pending  applications  are  important  in  establishing  and  maintaining  a  competitive  position  with  respect  to  our  products  and

technology.

APTO-253

We have been issued 21 patents and have 16 pending patents worldwide for our in-house small molecules.  These patents cover APTO-253 composition of matter and
methods of treating different cancers with APTO-253, including solid tumors and leukemia.   Composition of matter patents expire in 2028 in the United States and 2026 in
other countries.  Our patents also include several compounds that are similar to APTO-253, which provide protection from competitors seeking to develop anticancer products
that are related in chemical structure to APTO-253.

Regulatory Strategy

Our overall regulatory strategy is to work with the appropriate government departments which regulate the use and sale of therapeutic drug products. This includes
Health  Canada  in  Canada,  the  Food  and  Drug Administration  in  the  United  States,  the  European  Medicines Agency  in  Europe,  and  other  local  regulatory  agencies  with
oversight of preclinical studies, clinical trials and marketing of therapeutic products. Where possible, we intend to take advantage of opportunities for accelerated development
of drugs designed to treat rare and serious or life-threatening diseases. We also intend to pursue priority evaluation of any application for marketing approval filed in Canada, the
United  States  or  the  European  Union  and  to  file  additional  drug  applications  in  other  markets  where  commercial  opportunities  exist.  We  may  not  be  able  to  pursue  these
opportunities successfully.

Revenues

The Company has not earned substantial revenues from its drug candidates and is therefore considered to be in the development stage.

Employees

The  business  of  the  Company  requires  personnel  with  specialized  skills  and  knowledge  in  oncology.  Researchers  must  be  able  to  design  and  implement  studies  to
assess the efficacy of anticancer drugs. Specialized knowledge and skills relating to chemistry and formulation process development are also needed. Such knowledge and skills
are needed to develop product specific analytical methods and formulation processes. The Company’s business also requires clinical and regulatory expertise and knowledge.
The Company has trained scientists and personnel with broad experience in these fields.

As at December 31, 2016, we employed 21 full-time persons and 2 part-time persons in research and drug development and administration activities. Subsequent to
December 31, 2016, and as a result of the Company’s reprioritization of its pipeline, we executed a reduction in workforce bringing the total to 14 full-time persons and 3 part-
time research persons in research and drug development and administrative activities. Four of our employees hold Ph.D.’s and numerous others hold degrees and designations
such as MSc, BSc, CPA (CA), CPA (California) and MBA.

To encourage a focus on achieving long-term performance, employees and members of the Board have the ability to acquire an ownership interest in the Company

through Aptose’s share option and alternate compensation plans. See Item 6.B – Compensation.

None of our employees are unionized, and we consider our relations with our employees to be good.

Office Facilities

Our head office, which occupies 5,300 square feet, is located 5955 Airport Road Suite #228, Mississauga, Ontario. The leased premise is office space. Our current

lease expires in April, 2020.

We have executive offices in San Diego and have entered into a lease agreement for office space, located at 12770 High Bluffs Drive, San Diego, California which
occupies approximately 2,204 square feet. This leased premise is used for administrative purposes only. This lease expires January, 2020. In December 2016, we terminated the
lease  early,  at  no  cost,  on  our  administrative  offices  in  San  Francisco  located  at  3  Lagoon  Drive,  Redwood  City,  California.  The  original  lease  was  to  expire  in  June  2018.
Finally, we have leased laboratory space in San Diego at 3550 General Atomics Court. The lease is for 1,386 square feet and the lease expires in February 2018.

Components and Raw Materials

Standard  raw  materials,  component  parts,  and  products  required  by  the  Company  in  pursuing  its  activities  are  supplied  from  reputable  companies  active  in  the

biotechnology industry. Pricing is predictable as there are many alternatives of such supplies that are readily available.

Competition

The biotechnology and pharmaceutical industries are characterized by rapidly evolving technology and intense competition. There are numerous companies in these
industries  that  are  focusing  their  efforts  on  activities  similar  to  ours.  Some  of  these  are  companies  with  established  positions  in  the  pharmaceutical  industry  and  may  have
substantially more financial and technical resources, more extensive research and development capabilities, and greater marketing, distribution, production and human resources
than Aptose. In addition, we face competition from other companies for opportunities to enter into partnerships with biotechnology and pharmaceutical companies and academic
institutions.

Competition  with  our  potential  products  may  include  chemotherapeutic  agents,  monoclonal  antibodies,  antisense  therapies,  small  molecules,  immunotherapies,
vaccines and other biologics with novel mechanisms of action. These drugs may kill cancer cells indiscriminately, or through a targeted approach, and some have the potential
to be used in non-cancer indications. We also expect that we will experience competition from established and emerging pharmaceutical and biotechnology companies that have
other forms of treatment for the cancers that we target, including drugs currently in development for the treatment of cancer that employ a number of novel approaches for
attacking these cancer targets. Cancer is a complex disease with more than 100 indications requiring drugs for treatment. The drugs in competition with our potential drugs have
specific  targets  for  attacking  the  disease,  targets  which  are  not  necessarily  the  same  as  ours.  These  competitive  drugs,  however,  could  potentially  also  be  used  together  in
combination  therapies  with  our  drugs  to  manage  the  disease.  Other  factors  that  could  render  our  potential  products  less  competitive  may  include  the  stage  of  development,
where competitors’ products may achieve earlier commercialization, as well as superior patent protection, better safety profiles, or a preferred cost-benefit profile.

Environmental Compliance

The Company’s research and development activities involve the controlled use of hazardous and radioactive materials and, accordingly, the Company is subject to
federal,  provincial  and  local  laws  and  regulations  governing  the  use,  manufacture,  storage,  handling  and  disposal  of  such  materials  and  certain  waste  products.  To  the
knowledge  of  the  Company,  compliance  with  such  environmental  laws  and  regulations  does  not  and  will  not  have  any  significant  impact  on  its  capital  spending,  profits  or
competitive position within the normal course of its operating activities. There can be no assurance, however, that the Company will not be required to incur significant costs to
comply  with  environmental  laws  and  regulations  in  the  future  or  that  its  operations,  business  or  assets  will  not  be  materially  adversely  affected  by  current  or  future
environmental laws or regulations.

Government Regulation

Overview

Regulation(s)  by  government  authorities  in  Canada,  the  United  States,  and  the  European  Union  are  significant  factors  in  guiding  our  current  research  and  drug
development activities. To clinically test, manufacture and market drug products for therapeutic use, we must be in compliance with guidance and regulations established by the
regulatory agencies in the countries in which we currently operate or intend to operate.

The laws of most of these countries require the licensing of manufacturing facilities, carefully controlled research and the extensive testing of products. Biotechnology
companies  must  establish  the  safety  and  efficacy  of  their  new  products  in  clinical  trials;  they  must  establish  and  comply  with  current  GMP(s)  for  the  manufacturing  of  the
product and control over marketing activities before being allowed to market a product. The safety and efficacy of a new drug must be shown through human clinical trials of
the drug carried out in accordance with the guidance and regulations established by local and federal regulatory agencies.

The  process  of  completing  clinical  trials  and  obtaining  regulatory  approval  for  a  new  drug  takes  a  number  of  years  and  requires  the  expenditure  of  substantial
resources. Once a new drug or product license application is submitted, regulatory agencies may not review the application in a timely manner and may not approve the product.
Even after an NDA submission has occurred and or approval has been obtained, further studies, including post-marketing studies, may be required to provide additional data on
efficacy and safety necessary to confirm the approved indication or to gain approval for the use of the new drug as a treatment for clinical indications other than those for which
the new drug was initially tested. Also, regulatory agencies require post-marketing surveillance programs to monitor a new drug’s side effects, safety and long term effects of
the product. A serious safety or effectiveness problem involving an approved new drug, may result in a regulatory agency mandating a withdrawal of the new drug from the
market and possible civil action. It is possible that we could encounter such difficulties or excessive costs in our efforts to secure necessary approvals, which could delay or
prevent us from manufacturing or marketing our products.

In  addition  to  the  regulatory  product  approval  framework,  biotechnology  companies,  including Aptose,  are  subject  to  regulation  under  local,  provincial,  state  and
federal law, including requirements regarding occupational safety, laboratory practices, environmental protection and hazardous substance control, and may be subject to other
present and future local, provincial, state, federal and foreign regulation, including possible future regulation of the biotechnology industry.

Regulation in Canada

In Canada, the manufacture and sale of new drugs are controlled by Health Canada. New drugs must pass through a number of testing stages, including pre-clinical
testing and human clinical trials. Pre-clinical testing involves testing the new drug’s chemistry, pharmacology and toxicology  in vitro  and in vivo. Successful results (that is,
potentially valuable pharmacological activity combined with an acceptable low level of toxicity) enable the developer of the new drug to file a clinical trial application to begin
clinical trials involving humans.

To study a drug in Canadian patients, a clinical trial application submission must be filed with Health Canada. The clinical trial application submission must contain
specified information, including the results of the pre-clinical tests completed at the time of the submission and any available information regarding use of the drug in humans.
In addition, since the method of manufacture may affect the efficacy and safety of a new drug, information on manufacturing methods and standards and the stability of the drug
substance and dosage form must be presented. Production methods and quality control procedures must be in place to ensure an acceptably pure product, essentially free of
contamination, and to ensure uniformity with respect to all quality aspects.

In addition, all federally regulated trials must be approved and monitored by an independent committee of doctors, scientists, advocates and others to ensure safety and
ethical standards. These committees are called Institutional Review Boards (“IRBs”) or Ethics Review Boards (“ERBs”). The review boards study and approve all study-related
documents before a clinical trial begins and also carefully monitor data to detect benefit or harm, and validity of results.

31

 
 
 
 
 
  
 
 
 
 
 
Provided Health Canada does not reject a clinical trial application submission and IRB or ERB approval has been obtained, clinical trials can begin. Clinical trials for
product candidates in Canada, as in the U.S. generally are carried out in three phases. Phase I involves studies to evaluate toxicity and ideal dose levels in healthy humans. The
new drug is administered to human patients who have met the clinical trial entry criteria to determine pharmacokinetics, human tolerance and prevalence of any adverse side
effects. Phases II and III involve therapeutic studies. In Phase II, efficacy, dosage, side effects and safety are established in a small number of patients who have the disease or
disorder that the new drug is intended to treat. In Phase III, there are controlled clinical trials in which the new drug is administered to a large number of patients who are likely
to receive benefit from the new drug. In Phase III, the effectiveness of the new drug in patients is compared to that of standard accepted methods of treatment in order to provide
sufficient data for the statistical proof of safety and efficacy for the new drug.

If clinical studies establish that a new drug has value, the manufacturer submits a new drug submission application to Health Canada for marketing approval. The new
drug submission contains all information known about the new drug, including the results of pre-clinical testing and clinical trials. Information about a substance contained in
new  drug  submission  includes  its  proper  name,  its  chemical  name,  and  details  on  its  method  of  manufacturing  and  purification,  and  its  biological,  pharmacological  and
toxicological properties. The new drug submission also provides information about the dosage form of the new drug, including a quantitative listing of all ingredients used in its
formulation, its method of manufacture, manufacturing facility information, packaging and labelling, the results of stability tests, and its diagnostic or therapeutic claims and
side effects, as well as details of the clinical trials to support the safety and efficacy of the new drug. Furthermore, for biological products, an on-site evaluation is completed to
assess the production process and manufacturing facility. It is required prior to the issuance of a notice of compliance. All aspects of the new drug submission are critically
reviewed by Health Canada. If a new drug submission is found satisfactory, a notice of compliance is issued permitting the new drug to be sold for the approved use. In Canada,
an establishment license must be obtained prior to marketing the product.

Health Canada has a policy of priority evaluation of new drug submissions for all drugs intended for serious or life-threatening diseases for which no drug product has
received regulatory approval in Canada and for which there is reasonable scientific evidence to indicate that the proposed new drug is safe and may provide effective treatment.

The  monitoring  of  a  new  drug  does  not  cease  once  it  is  on  the  market.  For  example,  a  manufacturer  of  a  new  drug  must  report  any  new  information  received
concerning serious side effects, as well as the failure of the new drug to produce desired effects. If Health Canada determines it to be in the interest of public health, a notice of
compliance for a new drug may be suspended and the new drug may be removed from the market.

A post surveillance program involves clinical trials conducted after a drug is marketed (referred to as Phase IV studies in the United States) and is an important source
of information on as yet undetected adverse outcomes, especially in populations that may not have been involved in the premarketing trials (e.g., children, the elderly, pregnant
women) and the drug’s long-term morbidity and mortality profile. Regulatory authorities may require companies to conduct Phase IV studies as a condition of market approval.
Companies often conduct post-marketing studies in the absence of a regulatory mandate.

An exception to the foregoing requirements relating to the manufacture and sale of a new drug is the limited authorization that may be available in respect of the sale of
new  drugs  for  emergency  treatment.  Under  the  special  access  program,  Health  Canada  may  authorize  the  sale  of  a  quantity  of  a  new  drug  for  human  use  to  a  specific
practitioner  for  the  emergency  treatment  of  a  patient  under  the  practitioner’s  care.  Prior  to  authorization,  the  practitioner  must  supply  Health  Canada  with  information
concerning the medical emergency for which the new drug is required, such data as is in the possession of the practitioner with respect to the use, safety and efficacy of the new
drug, the names of the institutions at which the new drug is to be used and such other information as may be requested by Health Canada. In addition, the practitioner must
agree  to  report  to  both  the  drug  manufacturer  and  Health  Canada  the  results  of  the  new  drug’s  use  in  the  medical  emergency,  including  information  concerning  adverse
reactions, and must account to Health Canada for all quantities of the new drug made available.

The Canadian regulatory approval requirements for new drugs outlined above are similar to those of other major pharmaceutical markets. While the testing carried out
in Canada is often acceptable for the purposes of regulatory submissions in other countries, individual regulatory authorities may request supplementary testing during their
assessment of any submission. Therefore, the clinical testing conducted under Health Canada authorization or the approval of regulatory authorities of other countries may not
be accepted by regulatory authorities outside Canada or other countries.

32

 
 
 
 
 
 
 
 
Regulation in the United States

In the United States, the FDA controls and investigates the investigation, manufacturing, and sale of new drugs. New drugs require FDA approval of a New Drug
Application prior to commercial sale. In the case of certain biological products, a Biological License Application must be obtained prior to marketing and batch releasing. As in
Canada,  to  obtain  marketing  approval,  data  from  adequate  and  well-controlled  human  clinical  trials,  demonstrating  to  the  FDA’s  satisfaction  a  new  drug’s  safety  and
effectiveness for its intended use, are required. Data are generated in studies conducted pursuant to an IND submission, similar to that required for a clinical trial application in
Canada. Clinical trials with human subjects are characterized as Phase I, Phase II and Phase III trials or a combination thereof. In a marketing application, the manufacturer
must  also  demonstrate  the  identity,  potency,  quality  and  purity  of  the  active  ingredients  of  the  new  drug  involved,  and  the  stability  of  those  ingredients.  Further,  the
manufacturing facilities, equipment, processes and quality controls for the new drug must comply with the FDA’s current Good Manufacturing Practice regulations for drugs or
biological  products  both  in  a  pre-licensing  inspection  before  product  licensing  and  in  subsequent  periodic  inspections  after  licensing. An  establishment  license  grants  the
sponsor permission to fabricate, package, label, distribute, import, wholesale or test of the newly approved drug.

Federally  regulated  trials  must  be  approved  and  monitored  by  an  independent  committee  of  doctors,  scientists,  advocates  and  others  to  ensure  safety  and  ethical
standards.  These  committees  are  called  Institutional  Review  Boards  (“IRBs”)  or  Ethics  Review  Boards  (“ERBs”).  The  review  boards  study  and  approve  all  study-related
documents before a clinical trial begins and also carefully monitor data to detect benefit or harm, and validity of results.

The  above  describes  briefly  what  is  necessary  for  a  new  drug  to  be  approved  for  marketing  in  North America.  The  European  Medicines Agency  and  Japanese
Pharmaceuticals  and  Medical  Devices  Agency  are  also  important  regulatory  authorities  in  drug  development.  Together  with  the  FDA,  they  are  the  three  International
Conference on Harmonization parties which oversee the three largest markets for drug sales.

In determining the fair value of these option-based awards, the Black-Scholes valuation methodology was used with the following assumptions: (i) expected life of five
years; (ii) volatility 110%; (iii) risk free interest rate of 0.68%; and (iv) no dividend yield. The Company has decided to use the Black-Scholes valuation methodology
because it is equivalent to the option value reported in the Company’s consolidated financial statements.

Share Option Plan

The Share Option Plan was established to advance the interests of Aptose by:

·

·

·

·

·

providing Eligible Persons (as defined below) with additional incentives;

encouraging stock ownership by Eligible Persons;

increasing the interest of Eligible Persons in the success of Aptose;

encouraging Eligible Persons to remain loyal to Aptose; and

attracting new Eligible Persons to Aptose.

The Compensation Committee, as authorized by the Board, administers the Share Option Plan. The maximum total number of Common Shares available for issuance
from treasury under the Share Option Plan, together with the Stock Incentive Plan (“SIP”) and any other security based compensation arrangement is 17.5% of the Company’s
issued and outstanding Common Shares at any given time. Any exercise of options pursuant to the Share Option Plan will make new option grants available under the Share
Option Plan, provided that the maximum number of Common Shares reserved for issuance collectively under the Share Option Plan and the SIP may not exceed 17.5% of the
Company’s issued and outstanding Common Shares at any given time.

Under the Share Option Plan, options may be granted to any executive officer, employee, subsidiary of an executive officer or employee, or consultant or consultant
entity (“Eligible Persons”). The exercise price of options granted under the Share Option Plan is established by the Board and will be equal to the closing market price of the
Common Shares on the TSX on the last trading day preceding the date of grant. If there is no trading on that date, the exercise price will be the average of the bid and ask on the
TSX on the last trading date preceding the date of grant. If not otherwise determined by the Board, an option granted under the Share Option Plan will vest as to 50% on the first
anniversary of the date of grant of the option and 16.66% on the second, third and fourth anniversaries after the date of grant. The Board fixes the term of each option when
granted, but such term may not be greater than 10 years from the date of grant. If the date on which an option expires pursuant to an option agreement occurs during, or within
10 days after the last day of, a black out period or other restriction period imposed on the trading of Common Shares by the Company, the expiry date for the option will be the
last day of the 10-day period. Options are personal to the participant and a participant may not transfer an option except in accordance with the Share Option Plan.

The Board may, in its sole discretion, amend, suspend or terminate the Share Option Plan or any portion of it at any time in accordance with applicable legislation,
without obtaining the approval of Shareholders. Any amendment to any provision of the Share Option Plan is subject to any required regulatory or Shareholder approval. The
Company is, however, required to obtain the approval of the Shareholders for any amendment related to (i) the maximum number of Common Shares reserved for issuance
under the Share Option Plan, and under any other security based compensation arrangements of the Company; (ii) a reduction in the exercise price for options held by insiders
of the Company; and (iii) an extension to the term of options held by insiders of the Company.

If  an  option  holder  is  terminated  without  cause,  resigns  or  retires,  each  option  that  has  vested  will  cease  to  be  exercisable  three  months  after  the  option  holder’s
termination date. Any portion of an option that has not vested on or prior to the termination date will expire immediately. If an option holder is terminated for cause, each option
that has vested will cease to be exercisable immediately upon the Company’s notice of termination. Any portion of an option that has not vested on or prior to the termination
date will expire immediately.

Stock Incentive Plan

The Company adopted the SIP following shareholder approval on June 10, 2015 pursuant to which the Board may grant stock-based awards comprised of restricted
stock units (the “Restricted Stock Units”) or dividend equivalents (the “Dividend Equivalents” and collectively with the Restricted Stock Units, the “Awards”) to employees,
officers, consultants, independent contractors, advisors and non-employee directors of the Company or any affiliate (the “SIP Participants”).

The maximum total number of shares available for issuance under the SIP and any other security based compensation arrangement of the Company (including the
Share Option Plan) is 17.5% of the number of issued and outstanding shares. Any issuance of shares covered by an award or to which an award relates will make new grants
available under the SIP. Since the adoption of the SIP, no awards have been granted.

Under the SIP, the Board may also grant Dividend Equivalents to SIP Participants under which the Participant shall be entitled to receive payments (in cash, Shares,
other securities, other Awards or other property as determined in the discretion of the Committee) equivalent to the amount of cash dividends paid by the company to holders of
Shares with respect to a number of shares determined by the Board.

The SIP does not limit insider participation and does not provide a maximum number of Shares which may be issued to an individual under the SIP. However, no
director of the company who is not also an employee of the company or an affiliate may be granted any awards that exceed in the aggregate $150,000 (such value computed as
of the date of grant in accordance with applicable financial accounting principles) in any calendar year.

Subject to the express provisions of the SIP and to applicable law, the Board shall have full power and authority to: (i) designate SIP Participants; (ii) determine the
type of Awards to be granted to each SIP Participant under the SIP and the number of Shares to be covered by each Award; (iii) determine the terms and conditions of any
Award or Award Agreement, including any terms relating to the forfeiture of any Award and the forfeiture, recapture or disgorgement of any cash, Shares or other amounts
payable with respect to any Award; (iv) amend the terms and  conditions  of  any Award  or Award Agreement,  subject  to  the  limitations  under  Section  7  of  the  SIP;  and  (v)
accelerate the exercisability of any Award or the lapse of any restrictions relating to any Award, subject to the limitations in Section 7 of the SIP.

41

 
 
 
 
 
 
 
 
 
 
The  Board  may  from  time  to  time  amend,  suspend  or  terminate  the  SIP,  and  the  Board  may  amend  or  alter  any  previously  granted Award,  as  applicable,  without
obtaining the approval of Shareholders in order to: (i) correct any defect, supply any omission or reconcile any inconsistency in the SIP or in any Award or award agreement in
the manner and to the extent it shall deem desirable to implement or maintain the effectiveness of the SIP; (ii) amend the eligibility for, and limitations or conditions imposed
upon, participation in the SIP; (iii) make changes that are necessary or desirable to comply with applicable laws, rules, regulations and policies of any applicable governmental
entity or stock exchange; (iv) amend any terms relating to the administration of the SIP, including the terms of any administrative guidelines or other rules related to the SIP; or
(v) make any other amendment, whether fundamental or otherwise, not requiring Shareholders’ approval under TSX Company Manual, the rules or regulations of the United
States SEC or any other securities exchange that are applicable to the Company.

Prior approval of the shareholders shall be required for any amendment to the Plan or an Award that would: (i) require shareholder approval under the TSX Company
Manual, the rules or regulations of the SEC or any other securities exchange that are applicable to the Company; (ii) increase the maximum number of shares authorized under
the SIP; (iii) increase the annual limit on Awards granted to non-employee directors; or (iv) amend the amendment provision of the SIP.

Deferred Share Units Plan

The Company had a Deferred Share Unit Plan (“DSU Plan”) which was terminated on June 10, 2015.

During the period from January 1, 2015 to June 10, 2015, nil deferred share units were outstanding under the DSU Plan. No units have been outstanding under the

DSU Plan since April 2014.

Employee Share Purchase Plan

We have an Employee Share Purchase Plan (“ESPP”), the purpose of which is to assist the Company in retaining the services of its employees, securing and retaining
the services of new employees and providing incentives for such persons to exert maximum efforts for the success of the Company. The ESPP provides a means by which
employees  of  the  Company  and  its  affiliates  may  purchase  Common  Shares  on  the  stock  market  at  a  15%  discount  through  accumulated  payroll  deductions.  Eligible
participants in the ESPP include all employees, including executive officers, who work at least 20 hours per week and are customarily employed by the Company or an affiliate
of  the  Company  for  at  least  six  months  per  calendar  year.  Generally,  each  offering  is  of  three  months’  duration  with  purchases  occurring  every  quarter.  Participants  may
authorize payroll deductions of up to 15% of their base compensation for the purchase of Common Shares under the ESPP.

During the year ended December 31, 2016, under the ESPP, Named Executive Officers, as a group, and employees did not purchase any Common Shares pursuant to

the ESPP. Since December 31, 2016, there have been no Common Shares purchased pursuant to the ESPP.

Compensation Committee

Composition of the Compensation Committee

The  Board,  upon  the  advice  of  the  Compensation  Committee,  determines  executive  compensation.  The  Compensation  Committee  is  currently  comprised  of
independent Board members Dr. Burger, Dr. Platzer and Dr. Thompson. Dr. Burger is chair of the Compensation Committee. The Compensation Committee met 4 times during
the period from January 1, 2016, until December 31, 2016.

Members of the Compensation Committee each have direct experience relevant to compensation matters resulting from their respective current and past activities. The
members of the Compensation Committee have experience dealing with compensation matters in comparable organizations, including public companies, as well as companies
with a strong emphasis on governance in their current and former roles as principal executives.

Compensation Objectives and Philosophy

The Compensation Committee’s mandate is to review and advise the Board on the recruitment, appointment, performance, compensation, benefits and termination of
executive  officers.  The  Compensation  Committee  also  administers  and  reviews  procedures  and  policies  with  respect  to  the  Share  Option  Plan,  the  SIP,  employee  benefit
programs, pay equity and employment equity and reviews executive compensation disclosure where it is publicly disclosed.

Aptose’s executive compensation program is designed to:

·

·

·

attract and retain qualified, motivated and achievement-oriented individuals by offering compensation that is competitive in the industry and marketplace;

align executive interests with the interests of shareholders; and

ensure that individuals continue to be compensated in accordance with their personal performance and responsibilities and their contribution to the overall objectives
of the Company.

These objectives are achieved by offering executives and employees a compensation package that is competitive and rewards the achievement of both short-term and

long-term objectives of the Company. As such, our compensation package consists of three key elements:

·

·

·

base salary and initial share options;

short-term compensation incentives to reward corporate and personal performance through potential annual cash bonuses; and

long-term compensation incentives related to long-term increase in share value through participation in the Share Option and SIPs.

The Compensation Committee reviews each of these items on a stand-alone basis and also reviews compensation as a total package. Adjustments to compensation are

made as appropriate following a review of the compensation package as a whole.

Base Salary — Initial Share Options

In establishing base salaries, the objective of the Compensation Committee is to establish levels that will enable Aptose to attract and retain executive officers that can
effectively  contribute  to  the  long-term  success  of  the  Company.  Base  salary  for  each  executive  officer  is  determined  by  the  individual’s  skills,  abilities,  experience,  past
performance and anticipated future contribution to the success of Aptose. The members of the Compensation Committee use their knowledge of the industry and of industry
trends as well as independent third party consultants to assist with the determination of an appropriate compensation package for each executive officer. In certain cases, the
Compensation Committee may recommend inclusion of automobile allowances, fitness allowances and the payment of certain professional dues as a component of an overall
remuneration package for executives.

45

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In certain cases, executive officers may be granted share options on the commencement of employment with Aptose in accordance with the responsibility delegated to

each executive officer for achieving corporate objectives and enhancing shareholder value in accordance with those objectives.

Short-Term Compensation Incentives

The role of short-term compensation incentives at Aptose is to motivate our executive officers to achieve specified performance objectives for 2016 and to reward them
for their achievement in the event that those objectives are met. Each year, the Compensation Committee approves the annual corporate objectives encompassing scientific,
clinical,  regulatory,  business  and  corporate  development  and  financial  criteria.  The  annual  cash  bonus  for  the  executive  officers  is  based,  at  least  in  part,  on  the  level  of
achievement of these annual objectives, assuming these objectives are still relevant at the time of evaluation.

All corporate and executive officer objectives are reviewed by the Compensation Committee and approved by the Board. The Compensation Committee recommends

to the Board the awarding of bonuses, payable in cash, stock or share options, to reward extraordinary individual performance.

For each executive officer, during the year ended December 31, 2016, the annual cash bonuses ranged from 20% to 25% of base salary.

Cash bonuses are determined as soon as practicable after the end of the fiscal year and, for the Named Executive Officers (as defined hereinafter), are included in the

Summary Compensation Table in the year in respect of which they are earned.

Long-Term Incentive Plan

The  role  of  long-term  compensation  incentives  at  Aptose  is  to  reward  an  executive’s  contribution  to  the  attainment  of  Aptose’s  long-term  objectives,  align  an
executive’s performance with the long-term performance of Aptose and to provide an additional incentive for an executive to enhance shareholder value. Long-term incentive
compensation for directors, officers, employees and consultants is reviewed annually and is accomplished through the grant of share options under our Share Option Plan or
SIP.

The number of options granted for certain executives of Aptose for the year ended December 31, 2016, was based on achievement of both corporate and executive
officer objectives. The Compensation Committee approves the allocation of options and options are priced using the closing market price of the Common Shares on the TSX on
the last trading day prior to the date of grant. Options to purchase Common Shares expire ten years from the date of grant and vest over a term determined by the Compensation
Committee. The Compensation Committee takes into account previous grants of options when considering new grant of options.

The granting of options to Named Executive Officers is included in the Summary Compensation Table in the year in which they are earned.

Performance Metrics

The performance of the Named Executive Officers for the period ended December 31, 2016 was measured with respect to the following objectives:

1)

Identification of new drug product formulation for APTO-25, submission of the Root Cause analysis for APTO-253 to the FDA, and return of APTO-253 to the
clinic.

2) Expand pipeline with highly differentiated small molecule agent for hematologic malignancies

3) Analyze corporate structure, implement financing alternatives and consider Board composition

46

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
4) Other R&D goals related to pipeline assets

Each  of  the  above  objectives  is  weighted  at  40%,  30%,  20%  and  10%  respectively  in  relation  to  assessment  of  satisfaction  of  overall  corporate  objectives  and

determination of any general corporate bonuses.

Hedge or Offset Instruments

Named Executive Officers or directors are not permitted to purchase financial instruments that are designed to hedge or offset a decrease in market value of equity
securities granted as compensation or held, directly or indirectly, by Named Executive Officers or directors, including, for greater certainty, prepaid variable forward contracts,
equity swaps, collars, or units of exchange funds.

Risk Assessment of Compensation

The implications of the risks associated with the Company’s compensation practices were not considered by the Board or a committee of the Board.

Audit Committee

The  charter  of  our Audit  Committee  is  attached  as  Exhibit  11.2.  The  current  members  of  the Audit  Committee  are  Bradley  Thompson,  Denis  Burger  and  Warren
Whitehead. Mr. Warren Whitehead is the Chairman of the Audit Committee and has been considered to be the Financial Expert. Pursuant to Canadian securities laws, the Board
has determined that Messrs. Thompson, Burger and Whitehead are financially literate as all have experience in reviewing and analyzing the financial reports and ascertaining
the financial position of a corporation. Mr. Burger, in his previous position as Chairman and Chief Executive Officer of AVI Biopharma, is educated and experienced in reading
and analyzing financial statements. Mr. Burger has also served on the audit committee of three other publicly listed biotechnology companies. Dr. Thompson has experience
reading  and  interpreting  financial  statements  through  his  former  role  as  Chairman  and  CEO  of  a  publicly  listed  biotechnology  company  as  well  as  through  his  extensive
experience serving on various company boards.  Mr. Whitehead is a CPA (CMA) and has served as the Chief Financial Officer of Arius Research Inc. and Labopharm Inc.
Additionally,  we  believe  Mr.  Thompson,  Mr.  Whitehead  and  Mr.  Burger  qualify  as  “independent”  as  that  term  is  defined  in  the  relevant  securities  laws  relating  to  the
composition of the audit committee.

Audit Committee Mandate

The Audit Committee’s mandate is to assist the Board in fulfilling its oversight responsibilities. In particular, the Audit Committee:

(a)

(b)

(c)

(d)

(e)

serves  as  an  independent  and  objective  party  to  monitor  the  integrity  of  our  financial  reporting  process  and  systems  of  internal  controls  regarding  finance,
accounting, and legal compliance, including the review of our consolidated financial statements, MD&A and annual and interim results;

identifies and monitors the management of the principal risks that could impact our financial reporting;

monitors the independence and performance of our independent auditors, including the pre-approval of all audit fees and all permitted non-audit services;

provides an avenue of communication among the independent auditors, management, and the Board and

encourages continuous improvement of, and foster adherence to, our policies, procedures and practices at all levels.

47

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The Audit Committee is also responsible for implementing and overseeing our whistle-blowing procedures.

D.

Employees.

As at December 31, 2016, we employed 21 full-time persons and 2 part-time persons in research and drug development and administration activities. Subsequent to
December 31, 2016, and as a result of the Company’s reprioritization of its pipeline, we executed a reduction in workforce bringing the total to 14 full-time persons and 3 part-
time research persons in research and drug development and administrative activities. Of our employees four hold Ph.D.’s and numerous others hold degrees and designations
such as MSc, BSc, CPA (CA), CPA (California) and MBA. To encourage a focus on achieving long-term performance, employees and members of the Board have the ability to
acquire an ownership interest in the Company through Aptose’s share option and alternate compensation plans. See Item 6.B – Compensation.

Our ability to develop commercial products and to establish and maintain our competitive position in light of technological developments will depend, in part, on our
ability to attract and retain qualified personnel. There is a significant level of competition in the marketplace for such personnel. We believe that to date we have been successful
in  attracting  and  retaining  the  highly  skilled  personnel  critical  to  our  business.  We  have  also  chosen  to  outsource  activities  where  skills  are  in  short  supply  or  where  it  is
economically prudent to do so.

None of our employees are unionized, and we consider our relations with our employees to be good.

E.

Share ownership.

The  following  table  sets  forth  information  regarding  beneficial  ownership  of  our  Common  Shares  as  of  December  31,  2016  with  respect  to  our  Named  Executive

On November 29, 2013, the Company entered into an executive employment agreement with each of Gregory K. Chow and Avanish Vellanki in connection with their

appointments as Chief Financial Officer and Chief Business Officer, respectively, of the Company. 

The employment agreements for each of Dr. Rice, Mr. Chow and Mr. Vellanki provide that if they are terminated by the Company other than for cause, each of Dr.
Rice, Mr. Chow and Mr. Vellanki would be entitled under their respective agreements to a payment equivalent to 12 months of their respective annual base salaries at the time
of termination.  Dr. Rice’s current annual base salary represents U.S. $524,064, Mr. Chow’s current annual base salary represents U.S. $334,200, and Mr. Vellanki’s current
annual base salary represents U.S. $334,200.  They are each additionally entitled to an amount equal to the average bonus remuneration received from the Company during the
last  three  years  of  employment  completed  prior  to  the  termination  date,  prorated  based  on  the  number  of  days  the  executive  worked  during  the  year  of  the  termination.    In
addition, the employment agreements for each of Dr. Rice, Mr. Chow and Mr. Vellanki provide that certain payments related to health benefits continue to be made for a period
of 12 months following termination of their employment.

The employment agreements of each of Dr. Rice, Mr. Chow and Mr. Vellanki also provide for the grant of options to purchase Common Shares of the Company, at an
exercise price equal to the fair market value of the shares on the dates of grant.  In connection with the execution of his executive employment agreement, Dr. Rice received an
initial grant of a fully vested option to purchase 35,417 (425,000 pre-consolidation) Common Shares at an exercise price equal to the fair market value of the Common Shares on
the date of grant.  Pursuant to the terms of his executive employment agreement, upon satisfaction of the conditions in his agreement, Dr. Rice received additional grants of
options to purchase 5,281 (63,367 pre-consolidation), 65,136 (781,633 pre-consolidation) and 140,000 (1,680,000 pre-consolidation) Common Shares on December 10, 2013,
January 29, 2014 and April 10, 2014, respectively, at exercise prices equal to the fair market value of the Common Shares on the dates of grant.  The options vest in accordance
with the Company’s standard three year vesting term, at a rate of 50% of the shares subject to the option vest on the one-year anniversary of the date of grant and 25% vest on
each one-year anniversary thereafter.

In addition to the option grants to Mr. Chow and Mr. Vellanki described below, Mr. Chow and Mr. Vellanki each received two additional grants of options to purchase
35,417 (425,000 pre-consolidation) Common Shares pursuant to the terms of their respective executive employment agreements, on December 10, 2013 and April 10, 2014.  Of
the 35,417 (425,000 pre-consolidation) options granted on December 10, 2013 to Mr. Chow and Mr. Vellanki, 16,667 (200,000 pre-consolidation) vested immediately and the
remaining 18,750 (225,000 pre-consolidation) options vest 50% after one year, 25% after two years and 25% after three years from the date of grant. The options granted in
April 10, 2014 vest in equal monthly installments over 36 months from the date of grant.

The employment agreements of Dr. Rice, Mr. Chow and Mr. Vellanki also provide that, in the event of a change of control (as defined in the agreements), each of Mr.
Chow and Mr. Vellanki would be eligible to receive a payment equivalent to 18 months of their respective annual base salaries at the time of termination, plus an amount equal
to 150% of the average bonus remuneration received from the Company during the last three years of employment completed prior to the termination date, prorated based on
the number of days the executive worked during the year of the termination, as well as continuation of the payments related to health benefits for a period of 12 months
following the termination following a change of control.

Prior to the Company entering into the executive employment agreements with Mr. Chow and Mr. Vellanki, Aptose entered into a consulting agreement with each of

Mr. Chow and Mr. Vellanki, on November 4, 2013.  Pursuant to the consulting agreements, Mr. Chow provided services to the Company as acting Chief Financial Officer prior
to the date of his executive employment agreement and Mr. Vellanki provided services as acting Chief Business Officer prior to the date of his executive employment
agreement.  Mr. Chow and Mr. Vellanki each were compensated at the monthly rate of $20,833 for their services and each were granted a fully vested option to purchase 35,417
(425,000 pre-consolidation) Common Shares at an exercise price equal to the fair market value of the shares on the date of grant.

  B.

Memorandum and articles of association.

We are incorporated pursuant to the laws of Canada (Corporation Number: 6650309). Our articles of incorporation (“Articles”) and by-laws provide no restrictions as
to the nature of our business operations. Under Canadian law, a director must inform us, at a meeting of the Board, of any interest in a material contract or proposed material
contract with us. Directors may not vote in respect of any such contracts made with us or in any such contract in which a director is interested, and such directors shall not be
counted for purposes of determining a quorum. However, these provisions do not apply to (i) a contract relating primarily to their remuneration as a director, officer, employee
or  agent  of  the  Company  or  affiliate,  (ii)  a  contract  for  their  indemnity  or  insurance  as  permitted  under  the Canada  Business  Corporations  Act,  or  (iii)  a  contract  with  an
affiliate.

We are authorized to issue an unlimited number of Common Shares. Our shareholders have no rights to share in our profits, are subject to no redemption or sinking
fund provisions, have no liability for further capital calls and are not subject to any discrimination due to number of Common Shares owned. By not more than 50 days nor less
than seven days in advance of a dividend, the Board may establish a record date for the determination of the persons entitled to such dividend.

The rights of holders of our Common Shares can be changed at any time in a shareholder meeting where the modifications are approved by 66 2/3% of the Common

Shares represented by proxy or in person at a meeting at which a quorum exists.

All holders of our Common Shares are entitled to vote at annual or special meetings of shareholders, provided that they were shareholders as of the record date. The
record date for shareholder meetings may precede the meeting date by no more than 50 days and not less than 21 days, provided that notice by way of advertisement is given to
shareholders at least seven days before such record date. Notice of the time and place of meetings of shareholders may not be less than 21 nor greater than 50 days prior to the
date of the meeting. There are no:

·

·

·

·

limitations on share ownership;

provisions of the Articles or by-laws that would have the effect of delaying, deferring or preventing a change of control of our company;

by-law provisions that govern the ownership threshold above which shareholder ownership must be disclosed; and

conditions imposed by the Articles or by-laws governing changes in capital, but Canadian corporate law requires any changes to the terms of share capital be
approved by 66.66% of the Common Shares represented by proxy or in person at a shareholders’ meeting convened for that purpose at which a quorum exists.

Common Shares

Each holder of record of Common Shares, without par value, is entitled to one vote for each share held on all matters properly submitted to the shareholders for their

vote, except matters which are required to be voted on as a particular class or series of stock. Cumulative voting for directors is not permitted.

Holders of outstanding Common Shares are entitled to those dividends declared by the board of directors out of legally available funds. In the event of liquidation,
dissolution or winding up our affairs, holders of Common Shares are entitled to receive, pro rata, our net assets available after provision has been made for the preferential
rights of the holders of preferred stock, including any surplus available after such event of liquidation, dissolution or winding up of the affairs of the Company. Holders of
outstanding Common Shares have no pre-emptive, conversion or redemption rights. All of the issued and outstanding Common Shares are, and all unissued Common Shares,
when offered and sold will be, duly authorized, validly issued, fully paid and non-assessable. To the extent that additional Common Shares may be issued in the future, the
relative interests of the then existing shareholders may be diluted. There were 15,721,388 Common Shares issued and outstanding at December 31, 2016.

Common Shares Eligible for Future Sale

Future sales of substantial amounts of our Common Shares in the public market or even the perception that such sales may occur, could adversely affect the market

price for our Common Shares and could impair our future ability to raise capital through an offering of our equity securities.

As  at  March  28,  2017,  the  Company  had  18,849,224  Common  Shares  issued  and  outstanding.  In  addition,  as  of  March  28,  2017,  there  were  1,970,587  Common

Shares issuable upon the exercise of outstanding options to purchase an equal number of Common Shares at a weighted average price per share of $5.79.

Indemnification of Executive Officers and Directors

We  have  agreed  to  indemnify  our  executive  officers  and  directors  for  all  costs,  charges  and  expenses,  including  an  amount  paid  to  settle  an  action  or  satisfy  a
judgment, reasonably incurred by them in respect of any civil, criminal or administrative action or proceeding to which they are made a party by reason of being or having been
a director or officer, if (a) they acted honestly and in good faith with a view to our best interests, and (b) in the case of a criminal or administrative action or proceeding that is
enforced by a monetary penalty, they had reasonable grounds for believing that their conduct was lawful.

Exchange controls.

There is no law or governmental decree or regulation in Canada that restricts the export or import of capital, or affects the remittance of dividends, interest or other

payments to non-resident holders of our voting Common Shares, other than withholding tax requirements.

There is no limitation imposed by Canadian law or by our Articles or our other charter documents on the right of a non-resident to hold or vote voting Common Shares,
other than as provided by the Investment Canada Act, the North American Free Trade Agreement Implementation Act (Canada) and the World Trade Organization Agreement
Implementation Act.

The Investment Canada Act requires notification and, in certain cases, advance review and approval by the government of Canada of the acquisition by a non-Canadian
of control of a Canadian business, all as defined in the Investment Canada Act. Generally, the threshold for review will be higher in monetary terms for a member of the World
Trade Organization or North American Free Trade Agreement.

E.

Taxation.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The  following  discussion  is  limited  to  certain  material  U.S.  federal  income  tax  considerations  relating  to  the  purchase,  ownership  and  disposition  of  the  Common
Shares  by  U.S.  Holders  (as  defined  below).  This  discussion  applies  to  U.S.  Holders  that  hold  Common  Shares  as  capital  assets.  This  summary  is  for  general  information
purposes only and does not purport to be a complete analysis or listing of all potential U.S. federal income tax considerations that may apply to a U.S. Holder arising from and
relating to the acquisition, ownership, and disposition of Common Shares. Accordingly, this summary is not intended to be, and should not be construed as, legal or U.S. federal
income tax advice with respect to any U.S. Holder.

No legal opinion from U.S. legal counsel or ruling from the Internal Revenue Service (the “IRS”) has been requested, or will be obtained, regarding the U.S. federal
income tax consequences of the acquisition, ownership, and disposition of Common Shares. 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. In addition, because the authorities on which this summary is based are subject to various
interpretations, the IRS and the U.S. courts could disagree with one or more of the conclusions described in this summary.

This discussion is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), U.S. Treasury regulations promulgated thereunder and administrative
and judicial interpretations thereof, all as in effect on the date hereof and all of which are subject to change, possibly with retroactive effect. This summary does not discuss the
potential effects, whether adverse or beneficial, of any proposed legislation.

This discussion does not address all of the U.S. federal income tax considerations that may be relevant to specific U.S. Holders in light of their particular circumstances
or  to  U.S.  Holders  subject  to  special  treatment  under  U.S.  federal  income  tax  law  (such  as  certain  financial  institutions,  insurance  companies,  broker-dealers  and  traders  in
securities  or  other  persons  that  generally  mark  their  securities  to  market  for  U.S.  federal  income  tax  purposes,  tax-exempt  entities,  retirement  plans,  regulated  investment
companies,  real  estate  investment  trusts,  certain  former  citizens  or  residents  of  the  United  States,  persons  who  hold  Common  Shares  as  part  of  a  “straddle,”  “hedge,”
“conversion transaction,” “synthetic security” or integrated investment, persons that have a “functional currency” other than the U.S. dollar, persons that own (or are deemed to
own) 10% or more (by voting power or value) of our Common Shares, corporations that accumulate earnings to avoid U.S. federal income tax, partnerships and other pass-
through entities, and investors in such pass-through entities). This discussion does not address any U.S. state or local or non-U.S. tax considerations or any U.S. federal estate,
gift or alternative minimum tax considerations. In addition, except as specifically set forth below, this summary does not discuss applicable tax reporting requirements.

As used in this discussion, the term “U.S. Holder” means a beneficial owner of the Common Shares that is, for U.S. federal income tax purposes, (1) an individual
who is a citizen or resident of the United States, (2) a corporation (or entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the
laws of the United States, any state thereof, or the District of Columbia, (3) an estate the income of which is subject to U.S. federal income tax regardless of its source or (4) a
trust (x) with respect to which a court within the United States is able to exercise primary supervision over its administration and one or more United States persons have the
authority to control all of its substantial decisions or (y) that has elected under applicable U.S. Treasury regulations to be treated as a domestic trust for U.S. federal income tax
purposes.

55

 
 
 
 
 
 
 
 
 
 
 
 
  
 
If  an  entity  treated  as  a  partnership  for  U.S.  federal  income  tax  purposes  holds  the  Common  Shares,  the  U.S.  federal  income  tax  considerations  relating  to  an
investment in the Common Shares will depend in part upon the status and activities of such entity and the particular partner. Any such entity should consult its own tax advisor
regarding the U.S. federal income tax considerations applicable to it and its partners of the purchase, ownership and disposition of the Common Shares.

Persons holding Common Shares should consult their own tax advisors as to the particular tax considerations applicable to them relating to the purchase, ownership
and disposition of Common Shares, including the applicability of U.S. federal, state and local tax laws and non-U.S. tax laws.

Distributions

Subject to the discussion below under “Passive Foreign Investment Company Considerations,” a U.S. Holder that receives a distribution with respect to the Common
Shares generally will be required to include the gross amount of such distribution (before reduction for any Canadian withholding taxes) in gross income as a dividend when
actually or constructively received to the extent of the U.S. Holder’s pro rata share of our current and/or accumulated earnings and profits (as determined under U.S. federal
income  tax  principles).  To  the  extent  a  distribution  received  by  a  U.S.  Holder  is  not  a  dividend  because  it  exceeds  the  U.S.  Holder’s  pro  rata  share  of  our  current  and
accumulated earnings and profits, it will be treated first as a tax-free return of capital and reduce (but not below zero) the adjusted tax basis of the U.S. Holder’s Common
Shares. To the extent the distribution exceeds the adjusted tax basis of the U.S. Holder’s Common Shares, the remainder will be taxed as capital gain. Because we may not
calculate our earnings and profits under U.S. federal income tax principles, U.S. Holders should expect all distributions to be reported to them as dividends.

The U.S. dollar value of any distribution on the Common Shares made in Canadian dollars generally should be calculated by reference to the exchange rate between
the U.S. dollar and the Canadian dollar in effect on the date of receipt (or deemed receipt) of such distribution by the U.S. Holder regardless of whether the Canadian dollars so
received are in fact converted into U.S. dollars at that time. If the Canadian dollars received are converted into U.S. dollars on the date of receipt (or deemed receipt), a U.S.
Holder generally should not recognize currency gain or loss on such conversion. If the Canadian dollars received are not converted into U.S. dollars on the date of receipt (or
deemed receipt), a U.S. Holder generally will have a basis in such Canadian dollars equal to the U.S. dollar value of such Canadian dollars on the date of receipt (or deemed
receipt). Any gain or loss on a subsequent conversion or other disposition of such Canadian dollars by such U.S. Holder generally will be treated as ordinary income or loss and
generally will be income or loss from sources within the United States for U.S. foreign tax credit purposes. Different rules apply to U.S. Holders who use the accrual method of
tax accounting. Each U.S. Holder should consult its own U.S. tax advisors regarding the U.S. federal income tax consequences of receiving, owning, and disposing of foreign
currency.

Distributions  on  the  Common  Shares  that  are  treated  as  dividends  generally  will  constitute  income  from  sources  outside  the  United  States  for  foreign  tax  credit
purposes  and  generally  will  constitute  passive  category  income.  Such  dividends  will  not  be  eligible  for  the  “dividends  received”  deduction  generally  allowed  to  corporate
shareholders with respect to dividends received from U.S. corporations. Dividends paid by a “qualified foreign corporation” are eligible for taxation at a reduced capital gains
rate rather than the marginal tax rates generally applicable to ordinary income provided that a holding period requirement (more than 60 days of ownership, without protection
from the risk of loss, during the 121-day period beginning 60  days  before  the  ex-dividend  date)  and  certain  other  requirements  are  met.  However,  if  we  are  a  PFIC  for  the
taxable year in which the dividend is paid or the preceding taxable year (see discussion below under “—Passive Foreign Investment Company Considerations”), we will not be
treated as a qualified foreign corporation, and therefore the reduced capital gains tax rate described above will not apply. Each U.S. Holder is advised to consult its tax advisors
regarding the availability of the reduced tax rate on dividends.

56

 
 
 
 
 
 
  
If a U.S. Holder is subject to Canadian withholding tax on dividends paid on the holder’s Common Shares, the U.S. Holder may be eligible, subject to a number of
complex limitations, to claim a credit against its U.S. federal income tax for the Canadian withholding tax imposed on the dividends. A U.S. Holder may claim a deduction for
the Canadian withholding tax in lieu of a credit, but only for a year in which the U.S. Holder elects to do so for all creditable foreign income taxes. The rules governing the
foreign tax credit are complex. Each U.S. Holder is advised to consult its own tax advisor regarding the availability of the foreign tax credit under its particular circumstances.

Sale, Exchange or Other Disposition of Common Shares

Subject to the discussion below under “Passive Foreign Investment Company Considerations,” a U.S.  Holder  generally  will  recognize  capital  gain  or  loss  for  U.S.
federal  income  tax  purposes  upon  the  sale,  exchange  or  other  disposition  of  Common  Shares.  The  amount  of  gain  recognized  will  equal  the  excess  of  the  amount  realized
(i.e., the amount of cash plus the fair market value of any property received) over the U.S. Holder’s adjusted tax basis in the Common Shares sold or exchanged. The amount of
loss  recognized  will  equal  the  excess  of  the  U.S.  Holder’s  adjusted  tax  basis  in  the  Common  Shares  sold  or  exchanged  over  the  amount  realized.  Such  capital  gain  or  loss
generally will be long-term capital gain or loss if, on the date of sale, exchange or other disposition, the Common Shares were held by the U.S. Holder for more than one year.
Net long-term capital gain derived by a non-corporate U.S. Holder currently is subject to tax at reduced rates. The deductibility of a capital loss is subject to limitations. Any
gain or loss recognized from the sale, exchange or other disposition of Common Shares will generally be gain or loss from sources within the United States for U.S. foreign tax
credit purposes, except as otherwise provided in an applicable income tax treaty and if an election is properly made under the Code.

Passive Foreign Investment Company Considerations

In  general,  a  corporation  organized  outside  the  United  States  will  be  treated  as  a  PFIC  in  any  taxable  year  in  which  either  (1)  at  least  75%  of  its  gross  income  is
“passive income” or (2) at least 50% of the average quarterly value of its assets is attributable to assets that produce passive income or are held for the production of passive
income. Passive income for this purpose generally includes, among other things, dividends, interest, royalties, rents, and gains from commodities transactions and from the sale
or exchange of property that gives rise to passive income. In determining whether a foreign corporation is a PFIC, a proportionate share of the items of gross income and assets
of each corporation in which it owns, directly or indirectly, at least a 25% interest (by value) are taken into account.

We believe we were a PFIC for our taxable year ended December 31, 2016 based on the nature of our business, the projected composition of our gross income and the
projected composition and estimated fair market values of our assets, we expect to be a PFIC for our taxable year ending December 31, 2017 and may be a PFIC in subsequent
tax  years.  No  opinion  of  legal  counsel  or  ruling  from  the  IRS  concerning  our  status  as  a  PFIC  has  been  obtained  or  is  currently  planned  to  be  requested.  However,  the
determination of our PFIC status is made annually after the close of each taxable year and it is difficult to predict before such determination whether we will be a PFIC for any
given taxable year. Even if we determine that we are not a PFIC after the close of a taxable year, there can be no assurance that the Internal Revenue Service (the “ IRS”) will
agree with our conclusion. No assurance can be provided regarded our PFIC status, and neither we nor our United States counsel expresses any opinion with respect to our
PFIC status for the taxable year ended December 31, 2016 or for any other taxable year.

If we are a PFIC at any time when a U.S. Holder owns Common Shares, such U.S. Holder will generally be subject to federal tax under the excess distribution regime
on (1) distributions paid during a taxable year that are greater than 125% of the average annual distributions paid in the three preceding taxable years, or, if shorter, the U.S.
Holder’s holding period for the Common Shares, and (2) any gain recognized on a sale, exchange or other disposition (which would include a pledge) of Common Shares.
Under the excess distribution regime, the U.S. Holder’s tax liability will be determined by allocating such distribution or gain ratably to each day in the U.S. Holder’s holding
period for the Common Shares. The amount allocated to the current taxable year (i.e., the year in which the distribution occurs or the gain is recognized) and any year prior to
the first taxable year in which we were a PFIC in the holding period will be taxed as ordinary income earned in the current taxable year. The amount allocated to other taxable
years will be taxed at the highest marginal rate in effect (for individuals or corporations as applicable) for ordinary income in each such taxable year, and an interest charge,
generally that applicable to the underpayment of tax, will be added to the tax. Once we are a PFIC with respect to a particular U.S. Holder, we generally will remain a PFIC with
respect to the U.S. Holder, unless we cease to meet the gross income and asset tests described above and the U.S. Holder makes a “deemed sale” election with respect to all of
the U.S. Holder’s Common Shares. If such election is made, the U.S. Holder will be deemed to have sold the Common Shares held at their fair market value on the last day of
the last taxable year in which we qualified as a PFIC, and any gain from such deemed sale would be taxed under the excess distribution regime described above. After the
deemed sale election, the U.S. Holder’s Common Shares would not be treated as Common Shares of a PFIC unless we subsequently became a PFIC.

57

 
 
 
 
 
 
 
  
If we are a PFIC for any taxable year during which a U.S. Holder holds the Common Shares and one of our non-United States subsidiaries is also a PFIC (i.e., a lower-
tier PFIC), the U.S. Holder will be treated as owning a proportionate amount (by value) of the Common Shares of the lower-tier PFIC and will be subject to the rules described
above on certain distributions by the lower-tier PFIC and a disposition (or deemed disposition) of Common Shares of the lower-tier PFIC, even though the U.S. Holder would
not receive the distributions or the proceeds from the disposition of the Common Shares of the lower-tier PFIC. Each U.S. Holder is advised to consult its tax advisors regarding
the application of the PFIC rules to any of our subsidiaries.

The tax considerations that would apply if we were a PFIC would be different from those described above if a U.S. Holder were able to make a valid “qualified electing
fund,”  or  “QEF  election.”  We  do  not  intend  to  provide  U.S.  Holders  with  the  information  required  to  permit  them  to  make  a  QEF  election  and,  accordingly,  prospective
investors should assume that a QEF election will not be available.

A U.S. Holder may avoid taxation under the excess distribution regime if the holder makes a valid “mark-to-market” election. An electing U.S. Holder generally would
take into account as ordinary income each year, the excess of the fair market value of the Common Shares held at the end of the taxable year over the adjusted tax basis of such
Common Shares. The U.S. Holder would also take into account, as an ordinary loss each year, the excess of the adjusted tax basis of such Common Shares over their fair market
value at the end of the taxable year, but only to the extent of the excess of amounts previously included in income over ordinary losses deducted as a result of the mark-to-market
election. The U.S. Holder’s tax basis in the Common Shares would be adjusted to reflect any income or loss recognized as a result of the mark-to-market election. Any gain
from a sale, exchange or other disposition of the Common Shares in any taxable year in which we are a PFIC, (i.e., when we meet the gross income test or asset test described
above) would be treated as ordinary income and any loss from a sale, exchange or other disposition would be treated first as an ordinary loss (to the extent of any net mark-to-
market gains previously included in income) and thereafter as a capital loss. If we cease to be a PFIC, any gain or loss recognized by a U.S. Holder on the sale or exchange of
the Common Shares would be classified as a capital gain or loss.

A mark-to-market election is available to a U.S. Holder only for “marketable stock.” Generally, stock will be considered marketable stock if it is “regularly traded” on
a “qualified exchange” within the meaning of applicable U.S. Treasury regulations. A class of stock is regularly traded during any calendar year during which such class of
stock is traded, other than in de minimis quantities, on at least 15 days during each calendar quarter. The Common Shares should be marketable stock as long as they are listed
on the TSX and are regularly traded. A mark-to-market election will not apply to the Common Shares for any taxable year during which we are not a PFIC, but will remain in
effect with respect to any subsequent taxable year in which we again become a PFIC. Such election will not apply to any subsidiary that we own. Accordingly, a U.S. Holder
may continue to be subject to the PFIC rules with respect to any lower-tier PFICs notwithstanding the U.S. Holder’s mark-to-market election.

Each U.S. person who is a shareholder of a PFIC generally must file an annual report with the IRS containing certain information, and the failure to file such report
could result in the imposition of penalties on such U.S. person and in the extension of the statute of limitations with respect to federal income tax returns filed by such U.S.
person.

The  U.S.  federal  income  tax  rules  relating  to  PFICs  are  very  complex.  U.S.  Holders  are  urged  to  consult  their  own  tax  advisers  with  respect  to  the  purchase,
ownership and disposition of Common Shares, the consequences to them of an investment in a PFIC, any elections available with respect to the Common Shares and
the IRS information reporting obligations with respect to the purchase, ownership and disposition of Common Shares in the event we are considered a PFIC.

Additional Tax on Passive Income

Certain U.S. Holders that are individuals, estates or trusts (other than trusts that are exempt from tax) will be subject to a 3.8% tax on all or a portion of their “net
investment  income,”  which  includes  dividends  on  the  Common  Shares,  and  net  gains  from  the  disposition  of  the  Common  Shares.  Further,  excess  distributions  treated  as
dividends, gains treated as excess distributions, and mark-to-market inclusions and deductions are all included in the calculation of net investment income.

Treasury regulations provide, subject to the election described in the following paragraph, that solely for purposes of this additional tax, that distributions of previously
taxed income will be treated as dividends and included in net investment income subject to the additional 3.8% tax. Additionally, to determine the amount of any capital gain
from the sale or other taxable disposition of Common Shares that will be subject to the additional tax on net investment income, a U.S. Holder who has made a QEF election
will be required to recalculate its basis in the Common Shares excluding QEF election basis adjustments.

Alternatively, a U.S. Holder may make an election which will be effective with respect to all interests in controlled foreign corporations and QEF election held in that
year or acquired in future years. Under this election, a U.S. Holder pays the additional 3.8% tax on QEF election income inclusions and on gains calculated after giving effect to
related  tax  basis  adjustments.  U.S.  Holders  that  are  individuals,  estates  or  trusts  should  consult  their  own  tax  advisors  regarding  the  applicability  of  this  tax  to  any  of  their
income or gains in respect of the Common Shares.

Information Reporting with Respect to Foreign Financial Assets

U.S. individuals that own “specified foreign financial assets” with an aggregate fair market value exceeding certain threshold amounts generally are required to file an
information report on IRS Form 8938 with respect to such assets with their tax returns. Significant penalties may apply to persons who fail to comply with these rules. Specified
foreign financial assets include not only financial accounts maintained in foreign financial institutions, but also, unless held in accounts maintained by a financial institution,
any stock or security issued by a non-U.S. person. Upon the issuance of future U.S. Treasury regulations, these information reporting requirements may apply to certain U.S.
entities  that  own  specified  foreign  financial  assets.  The  failure  to  report  information  required  under  the  current  regulations  could  result  in  substantial  penalties  and  in  the
extension of the statute of limitations with respect to federal income tax returns filed by a U.S. Holder. U.S. Holders should consult their own tax advisors regarding the possible
implications of these U.S. Treasury regulations for an investment in our Common Shares.

Special Reporting Requirements for Transfers to Foreign Corporations

A U.S. Holder that acquires Common Shares generally will be required to file Form 926 with the IRS if (1) immediately after the acquisition such U.S. Holder, directly
or indirectly, owns at least 10% of the Common Shares, or (2) the amount of cash transferred in exchange for Common Shares during the 12-month period ending on the date of
the  acquisition  exceeds  US$100,000.  Significant  penalties  may  apply  for  failing  to  satisfy  these  filing  requirements.  U.S.  Holders  are  urged  to  contact  their  tax  advisors
regarding these filing requirements.

Information Reporting and Backup Withholding

Dividends on and proceeds from the sale or other disposition of Common Shares may be reported to the IRS unless the U.S. Holder establishes a basis for exemption.
Backup withholding may apply to amounts subject to reporting if (1) the holder fails to provide an accurate taxpayer identification number or otherwise establish a basis for
exemption, or (2) is described in certain other categories of persons.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules generally will be allowed as a refund or a credit against a U.S.

Holder’s U.S. federal income tax liability if the required information is furnished by the U.S. Holder on a timely basis to the IRS.

THE  DISCUSSION  ABOVE  IS  A  GENERAL  SUMMARY.  IT  DOES  NOT  COVER  ALL  TAX  MATTERS  THAT  MAY  BE  OF  IMPORTANCE  TO  A  US
HOLDER. EACH US HOLDER IS URGED TO CONSULT ITS OWN TAX ADVISOR ABOUT THE TAX CONSEQUENCES TO IT OF AN INVESTMENT IN
COMMON SHARES IN LIGHT OF THE INVESTOR’S OWN CIRCUMSTANCES.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

The following is, as of the date hereof, a summary of the principal Canadian federal income tax considerations under the Income Tax Act (Canada) (the “Tax Act ”)
generally applicable to a holder of Common Shares of the Company who, for purposes of the Tax Act and at all relevant times, is neither resident in Canada nor deemed to be
resident in Canada for purposes of the Tax Act and any applicable income tax treaty or convention, and who does not use or hold (and is not deemed to use or hold) Common
Shares  in  carrying  on  a  business  in  Canada,  deals  at  arm’s  length  with  and  is  not  affiliated  with  the  Company  and  holds  Common  Shares  as  capital  property  (a  “Holder”).
Generally, Common Shares will be considered to be capital property to a Holder thereof provided that the Holder does not hold Common Shares in the course of carrying on a
business of buying and selling securities and such Holder has not acquired them in one or more transactions considered to be an adventure or concern in the nature of trade.

This summary does not apply to a Holder (i) that is a “financial institution” for purposes of the mark-to-market rules contained in the Tax Act; (ii) that is a “specified
financial institution” as defined in the Tax Act; (iii) an interest in which is a “tax shelter investment” as defined in the Tax Act; or (iv) that has elected to report its tax results in
a functional currency other than Canadian currency. Special rules, which are not discussed in this summary, may apply to a Holder that is an “authorized foreign bank” within
the meaning of the Tax Act or an insurer carrying on business in Canada and elsewhere. Such Holders should consult their own tax advisors.

This summary is based upon the provisions of the Tax Act (including the regulations (“Regulations”) thereunder) in force as of the date hereof and our understanding
of  the  current  administrative  policies  and  assessing  practices  of  the  Canada  Revenue Agency  (the  “CRA”)  published  in  writing  by  the  CRA  prior  to  the  date  hereof.  This
summary takes into account all specific proposals to amend the Tax Act (and the Regulations) publicly announced by or on behalf of the Minister of Finance (Canada) prior to
the date hereof (the “Tax Proposals”) and assumes that the Tax Proposals will be enacted in the form proposed, although no assurance can be given that the Tax Proposals will
be enacted in their current form or at all. This summary does not otherwise take into account any changes in law or in the administrative policies or assessing practices of the
CRA, whether by legislative, governmental or judicial decision or action. This summary is not exhaustive of all possible Canadian federal income tax considerations, and does
not take into account other federal or any provincial, territorial or foreign income tax legislation or considerations, which may differ materially from those described in this
summary.

This summary is of a general nature only and is not, and is not intended to be, and should not be construed to be, legal or tax advice to any particular Holder, and no
representations concerning the tax consequences to any particular Holder are made. Holders should consult their own tax advisors regarding the income tax considerations
applicable to them having regard to their particular circumstances.

Dividends

Dividends paid or credited (or deemed to be paid or credited) to a 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. For example, under the Canada-United States Income Tax Convention (1980) (the “ US Treaty”), as amended, the dividend withholding
tax rate is generally reduced to 15% in respect of a dividend paid or credited to a Holder beneficially entitled to the dividend who is resident in the U.S. for purposes of the US
Treaty and whose entitlement to the benefits of the US Treaty is not limited by the limitation of benefits provisions of the US Treaty. Holders are urged to consult their own tax
advisors to determine their entitlement to relief under the US Treaty or any other applicable tax treaty as well as their ability to claim foreign tax credits with respect to any
Canadian withholding tax, based on their particular circumstances.

60

 
 
 
 
 
 
 
 
Disposition of Common Shares

A Holder generally will not be subject to tax under the Tax Act in respect of a capital gain realized on the disposition or deemed disposition of a Common Share,
unless the Common Share constitutes or is deemed to constitute “taxable Canadian property” to the Holder thereof for purposes of the Tax Act, and the gain is not exempt from
tax pursuant to the terms of an applicable tax treaty or convention.

In general, provided the Common Shares are listed on a “designated stock exchange” (which currently includes the TSX) at the date of the disposition, the Common
Shares will only constitute “taxable Canadian property” of a Holder if, at any time within the 60-month period preceding the disposition: (i) such Holder, persons with whom the
Holder did not deal at arm's length, partnerships in which the Holder or a person with whom the Holder did not deal at arm’s length holds a membership interest directly or
indirectly through one or more partnerships, or any combination thereof, owned 25% or more of the issued shares of any class or series of the Company’s capital stock, and (ii)
more than 50% of the fair market value of the Common Shares was derived directly or indirectly from one or any combination of (A) real or immovable property situated in
Canada, (B) Canadian resource properties, (C) timber resource properties, and (D) options in respect of, or interests in, or for civil law rights in, property described in any of
subparagraphs  (ii)(A)  to  (C),  whether  or  not  the  property  exists.  However,  and  despite  the  foregoing,  in  certain  circumstances  the  Common  Shares  may  be  deemed  to  be
“taxable Canadian property” under the Tax Act.

Holders whose Common Shares may be “taxable Canadian property” should consult their own tax advisers.

  Item 11.

Qualitative and Quantitative Disclosures About Market Risk

Refer to notes 4 and 8 to the consolidated financial statements contained in Item 18.

We are exposed to significant market risks as outlined below.

We do not utilize derivative financial instruments to hedge our interest rate or foreign currency rate risks.

Interest Rate Risk

The Company invests its cash resources in liquid government and corporate debt instruments. We do not believe that the results of operations or cash flows would be
affected  to  any  significant  degree  by  a  sudden  change  in  market  interest  rates  relative  to  interest  rates  on  our  investments,  owing  to  the  relative  short-term  nature  of  the
investments.

Credit Risk

Financial instruments potentially exposing the Company to a concentration of credit risk consist principally of cash and cash equivalents and marketable securities. The
Company manages this credit risk by maintaining bank accounts with Schedule I banks and investing only in highly rated Canadian securities that are traded on active markets
and are capable of prompt liquidation.

Exchange Rate Sensitivity

The functional currency of the Company is the Canadian dollar. We are exposed to currency risk from employee costs as well as the purchase of goods and services
primarily  in  the  United  States  and  on  cash  balances  held  in  foreign  currencies.  Fluctuations  in  the  US  dollar  exchange  rate  could  have  a  significant  impact  on  our  results.
Assuming all other variables remain constant, a 10% depreciation or appreciation of the Canadian dollar against the US dollar would result in an increase or decrease in loss for
the year and comprehensive loss of $638 thousand (December 31, 2015 - $576 thousand, December 31, 2014- $50 thousand). Balances in foreign currencies are as follows:

(in thousands)

Cash and cash equivalents
Accounts payable and accrued liabilities
Balance, end of period

We do not have any forward exchange contracts to hedge this risk.

Limitations

The above discussion includes only those exposures that exist as of December 31, 2016, and as a result, does not consider exposures or positions that could arise after

that date. The Company’s ultimate realized gain or loss with respect to interest rate and exchange rate fluctuations would depend on the exposures that arise during the period.

Controls and Procedures

(a)

Disclosure controls and procedures.

As of the end of the year ended December 31, 2016, an evaluation of the effectiveness of our “disclosure controls and procedures” (as such term is defined in Rules
13a-15(e) and 15d-15(e) under the Exchange Act), was carried out by our management under the supervision of and with the participation of the principal executive officer and
principal financial officer. Based upon on that evaluation, our principal executive officer and principal financial officer have concluded that as of the end of that period, our
disclosure  controls  and  procedures  were  effective  to  ensure  that  information  required  to  be  disclosed  by  us  in  reports  that  we  file  or  submit  under  the  Exchange Act  is  (i)
recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and (ii) accumulated and communicated to our management, including
our principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure.

It should be noted that while our principal executive officer and principal financial officer believe that our disclosure controls and procedures are effective and provide
a reasonable level of assurance, they do not expect that the disclosure controls and procedures or internal control over financial reporting will prevent all errors and fraud. A
control system, no matter how well conceived or operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.

  (b)

Management’s annual report on internal control over financial reporting.

Management is responsible for establishing and maintaining adequate internal control over our financial reporting (as such term is defined in Rules 13a-15(f) and 15d-
15(f)  under  the  Exchange Act).  Our  internal  control  system  was  designed  to  provide  reasonable  assurance  that  all  transactions  are  accurately  recorded,  that  transactions  are
recorded as necessary to permit preparation of consolidated financial statements in accordance with IFRS as issued by the IASB, and that our assets are safeguarded.

Management has assessed the effectiveness of our internal control over financial reporting as at December 31, 2016. In management’s opinion, our internal control
over  financial  reporting  is  effective  as  at  December  31,  2016.  In  making  its  assessment,  management  used  the  Committee  of  Sponsoring  Organizations  of  the  Treadway
Commission framework in Internal Control – Integrated Framework of 2003 to evaluate the effectiveness of 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 future events. There can be no assurance that any

design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.

  (c)

Attestation report of the independent registered public accounting firm.

Because we are a non-accelerated filer and an “emerging growth company” under the rules of the SEC, this Annual Report is not required to include, and does not

include, an attestation report of our independent registered public accounting firm with respect to our internal control over financial reporting.

There has been no change in our internal control over financial reporting during the period covered by this Annual Report that has materially affected, or is reasonably

likely to materially affect, our internal control over financial reporting.

Chartered Professional Accountants of Ontario.

Our charter requires Audit Committee pre-approval of all permitted audit, audit-related and tax services.

Subject to the charter, the Audit Committee may establish fee thresholds for a group of pre-approved services. The Audit Committee then recommends to the board of

directors approval of the fees and other significant compensation to be paid to the independent auditors.

Corporate Governance

On October 23, 2014, we listed our Common Shares for trading on NASDAQ.  Section 5615(a)(3) of the NASDAQ Marketplace Rules permits NASDAQ to grant exemptions
to a foreign private issuer for the provisions of the Rule 5600 series and Rule 5250 (d).  We are organized under the laws of Canada and our Common Shares are listed for
trading on the TSX.  We comply with the laws of Canada and rules and regulations of the TSX, including rules related to corporate governance practices.  A description of the
significant ways in which our governance practices differ from those followed by domestic companies pursuant to the NASDAQ Marketplace Rules is as follows:

Shareholder Meeting Quorum Requirement: The NASDAQ minimum quorum requirement for a shareholder meeting under Section 5620(c) of the NASDAQ Marketplace
Rules is one-third of the outstanding shares of common stock.  In addition, a company listed on NASDAQ is required to state a quorum requirement in its bylaws.  Our quorum
requirement is set forth in our corporate bylaws.  A quorum for our shareholder meeting is not less than 25% of the outstanding shares of the Company entitled to be voted at
such meeting present or by means of a telephonic, electronic or other communication facility that permits all participants to communicate adequately with each other during the
meeting and each entitled to vote at the meeting.

Compensation  Committee  Mandate:  NASDAQ  will  require  compliance  with  the  revised  Rule  5605(d)  for  all  companies  following  the  company's  first  annual  meeting
occurring  after  January  15,  2014,  or  October  31,  2014,  whichever  is  earlier.  In  our  case  this  was  following  our August  19,  2014  annual  general  and  special  meeting.  The
changes to the rule include requiring the mandate of the Compensation Committee to include accountability to external advisors. The Compensation Committee Mandate does
not currently include such requirements.

The foregoing is consistent with the laws, customs and practices in Canada and the rules of the TSX.

 Management’s Responsibility for Financial Reporting

The  accompanying  consolidated  financial  statements  of  Aptose  Biosciences  Inc.  and  other  financial  information  contained  in  this  annual  report  are  the  responsibility  of
Management and have been approved by the Board of the Company.

The consolidated financial statements have been prepared in conformity with International Financial Reporting Standards as issued by the International Accounting Standards
Board, using Management’s best estimates and judgments where appropriate. In the opinion of Management, these consolidated financial statements reflect fairly the financial
position and the results of operations and cash flows of the Company within reasonable limits of materiality. The financial information contained elsewhere in this annual report
has been reviewed to ensure consistency with that in the consolidated financial statements. The integrity and objectivity of data in the financial statements and elsewhere in this
annual report are the responsibility of Management.

In discharging its responsibility for the integrity and fairness of the financial statements, management maintains a system of internal controls designed to provide reasonable
assurance, at appropriate cost, that transactions are authorized, assets are safeguarded and proper records are maintained. Management believes that the internal controls provide
reasonable  assurance  that  financial  records  are  reliable  and  form  a  proper  basis  for  the  preparation  of  the  consolidated  financial  statements,  and  that  assets  are  properly
accounted for and safeguarded. The internal control process includes management’s communication to employees of policies that govern ethical business conduct.

The Board, through an Audit Committee, oversees management’s responsibilities for financial reporting. This committee, which consists of three independent directors, reviews
the audited consolidated financial statements and recommends the financial statements to the Board for approval. Other key responsibilities of the Audit Committee include
reviewing the adequacy of the Company’s existing internal controls, audit process and financial reporting with management and the external auditors.

The consolidated financial statements have been audited by KPMG LLP, Chartered Professional Accountants, who are independent auditors appointed by the shareholders of
the Company upon the recommendation of the Audit Committee. Their report follows. The independent auditors have free and full access to the Audit Committee.

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors of Aptose Biosciences Inc.

We have audited the accompanying consolidated statements of financial position of Aptose Biosciences Inc. as of December 31, 2016 and December 31, 2015 and the related
consolidated statements of loss and comprehensive loss, changes in shareholders’ equity and cash flows for each of the years in the two-year period ended December 31, 2016
and  the  seven-month  period  ended  December  31,  2014.  These  consolidated  financial  statements  are  the  responsibility  of  Aptose  Biosciences  Inc.'s  management.  Our
responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United
States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for
our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Aptose Biosciences Inc. as of
December  31,  2016  and  December  31,  2015,  and  its  consolidated  financial  performance  and  its  consolidated  cash  flows  for  each  of  the  years  in  the  two-year  period  ended
December  31,  2016  and  the  seven-month  period  ended  December  31,  2014  in  conformity  with  International  Financial  Reporting  Standards as  issued  by  the  International
Accounting Standards Board.

1.

Reporting entity:

Aptose  Biosciences  Inc.  ("Aptose"  or  the  "Company")  is  a  clinical-stage  biotechnology  company  committed  to  discovering  and  developing  personalized  therapies
addressing unmet medical needs in oncology. Aptose is a publicly listed company incorporated under the laws of Canada. The Company's shares are listed on the Nasdaq
Capital Markets and the Toronto Stock Exchange. The head office, principal address and records of the Company are located at 5955 Airport Road, Mississauga, Ontario,
Canada, L4V 1R9.

Aptose changed its name from Lorus Therapeutics Inc. effective August 28, 2014.

The current reporting fiscal period is for the year ended December 31, 2016, while the prior comparative periods are for the year ended December 31, 2015 and for the
seven months ended December 31, 2014. On July 17, 2014, the Company changed its fiscal year end from May 31 to December 31. As a result of that change, the prior
period of the seven months ended December 31, 2014 is not directly comparable to the twelve months periods ended December 31, 2016 and 2015.

Basis of presentation:

(a) Statement of compliance:

These consolidated financial statements of the Company and its subsidiaries are prepared in accordance with International Financial Reporting Standards ("IFRS") as
issued by the International Accounting Standards Board ("IASB"). The consolidated financial statements of the Company were approved and authorized for issue by
the Board of Directors on March 28, 2017.

(b) Functional and presentation currency:

The functional and presentation currency of the Company is the Canadian dollar.

(c) Significant accounting judgments, estimates and assumptions:

The preparation of these consolidated financial statements in accordance with IFRS requires management to make judgments, estimates and assumptions that affect
the  application  of  accounting  policies  and  reported  amounts  of  assets  and  liabilities  at  the  date  of  the  consolidated  financial  statements  and  reported  amounts  of
revenue and expenses during the reporting period. Actual outcomes could differ from those estimates. The consolidated financial statements include estimates, which,
by their nature, are uncertain.

Years ended December 31, 2016 and 2015, Seven Months ended December 31, 2014

2.       Basis of presentation (continued):

Management’s  assessment  of  the  Company’s  ability  to  continue  as  a  going  concern  involves  making  a  judgment,  at  a  particular  point  in  time,  about  inherently
uncertain future outcomes and events or conditions. Please see note 8 (b) (ii) for a discussion of the factors considered by management in arriving at its assessment.

The impacts of such estimates are pervasive throughout the consolidated financial statements and may require accounting adjustments based on future occurrences.

The estimates and underlying assumptions are reviewed on a regular basis. Revisions to accounting estimates are recognized in the period in which the estimate is
revised and in any future periods affected.

The key assumptions concerning the future and other key sources of estimation uncertainty as of the date of the statement of financial position that have a significant
risk of causing material adjustment to the carrying amounts of assets and liabilities within the next fiscal year include:

(i) Valuation of contingent liabilities:

The Company utilizes considerable judgment in the measurement and recognition of provisions and the Company's exposure to contingent liabilities. Judgment is
required to assess and determine the likelihood that any potential or pending litigation or any and all potential claims against the Company may be successful. The
Company  must  estimate  if  an  obligation  is  probable  as  well  as  quantify  the  possible  economic  cost  of  any  claim  or  contingent  liability.  Such  judgments  and
assumptions are inherently uncertain. The increase or decrease of one of these assumptions could materially increase or decrease the fair value of the liability and
the associated expense.

(ii) Valuation of tax accounts:

The Company has deductible temporary differences which create a deferred tax asset. Deferred tax assets are recognized for all deductible temporary differences
to  the  extent  that  it  is  probable  that  future  taxable  profit  will  be  available  against  which  the  deductible  temporary  differences  can  be  utilized.  Management
judgment is required to determine the amount of deferred tax assets that can be recognized, based upon the likely timing and the level of future taxable profits..
To date, the Company has determined that none of its deferred tax assets should be recognized. The Company's deferred tax assets are mainly comprised of its
net  operating  losses  from  prior  years  and  prior  years’  research  and  development  expenses  not  yet  deducted  for  income  tax  purposes.  The  generation  of  future
taxable income could result in the recognition of some portion or all of the remaining benefits, which could result in an improvement in the Company's results of
operations through the recovery of future income taxes.

2.       Basis of presentation (continued):

(iii) Valuation of share-based compensation and share purchase warrants:

Management measures the costs for share-based payments and share purchase warrants using market-based option valuation techniques. Assumptions are made
and  judgment  is  used  in  applying  valuation  techniques.  These  assumptions  and  judgments  include  estimating  the  future  volatility  of  the  share  price,  expected
dividend  yield,  and  employee  turnover  rates.  Such  judgments  and  assumptions  are  inherently  uncertain.  The  increase  or  decrease  of  one  of  these  assumptions
could materially increase or decrease the fair value of share-based payments and share purchase warrants issued and the associated expense.

3.       Significant accounting policies:

(a) Basis of consolidation:

The consolidated financial statements include the accounts of the Company its 80% owned subsidiary, NuChem Pharmaceuticals Inc. (“NuChem”), its 100% owned
subsidiaries Aptose Biosciences Inc. USA (“Aptose USA”) and Aptose Suisse GmbH (“Aptose Suisse”). A subsidiary is
an entity over which the Company has control, being the power to govern the financial and operating policies of the investee entity so as to obtain benefits from its
activities. Accounting policies of the subsidiaries are consistent with the Company's accounting policies. All intra-group transactions, balances, revenue and expenses
are eliminated on consolidation.

(b) Foreign currency translation:

Foreign currency transactions are translated into Canadian dollars at rates prevailing on the transaction dates. At the end of each reporting period, monetary assets and
liabilities  denominated  in  foreign  currencies  are  translated  into  Canadian  dollars  at  the  rates  in  effect  at  that  date.  Gains  or  losses  resulting  from  the  translation  to
Canadian dollars are presented in the statement of loss and comprehensive loss for the period within finance income or expense.

(c) Derecognition of financial assets and liabilities:

A financial asset is derecognized when the right to receive cash flows from the asset have expired or when the Company has transferred its rights to receive cash flows
from the asset.

A financial liability is derecognized when its contractual obligations are discharged, cancelled or expire.

3.       Significant accounting policies (continued):

(d) Financial assets and liabilities:

Financial assets within the scope of IAS 39, Financial Instruments - Recognition and Measurement ("IAS 39"), are classified as either financial assets at fair value
through profit or loss, loans and receivables, held-to-maturity investments or available-for-sale financial assets, as appropriate. When financial assets are recognized
initially,  they  are  measured  at  fair  value,  plus,  in  the  case  of  financial  assets  not  at  fair  value  through  profit  or  loss,  directly  attributable  transaction  costs.  The
Company determines the classification of its financial assets at initial recognition and, where allowed and appropriate, re-evaluates this designation at each financial
year end.

The Company's financial instruments are comprised of the following: 

Financial assets

Classification

Cash and cash equivalents

Loans and receivables

Financial liabilities

Classification

Accounts payable, accrued liabilities

Other liabilities

Measurement

Amortized cost

Measurement

Amortized cost

The Company considers unrestricted cash on hand and guaranteed investment certificates held by Canadian Schedule A banks with original maturities of three months
or less as cash and cash equivalents.

Fair value:

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement
date. The fair value hierarchy establishes three levels to classify the inputs to valuation techniques used to measure fair value.

·

·

Level 1 - inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities;

Level 2 - inputs are quoted prices in markets that are not active, quoted prices for similar assets or liabilities in active markets, inputs other than quoted prices that
are observable for the asset or liability, or inputs that are derived principally from or corroborated by observable market data or other means; and

3.

Significant accounting policies (continued):

·

Level 3 - inputs are unobservable (supported by little or no market activity). The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest
priority to Level 3 inputs.

(e) Equipment:

Equipment  is  measured  at  cost  less  accumulated  depreciation  and  accumulated  impairment  losses.  Cost  includes  expenditures  that  are  directly  attributable  to  the
acquisition of the asset. The Company records depreciation at rates that charge operations with the cost of the assets over their estimated useful lives on a straight-line
basis as follows:

Furniture 
Laboratory Equipment 
Computer hardware
Leasehold improvements

3 years
5 years
3 years
Life of lease

The assets' residual value, useful life and methods of depreciation are reviewed at each reporting period and adjusted prospectively if appropriate.

(f)

Intangible assets:

Intangible  assets  are  recorded  at  cost  less  accumulated  amortization  and  accumulated  impairment  losses.  The  Company's  intangible  assets  consist  of  computer
application software that is not an integral part of the related hardware. Subsequent expenditures that increase application software functionality are recognized in the
carrying amount of intangible assets if they embody future economic benefit to the Company. All other costs including the costs of day-to-day servicing of intangible
assets are expensed as incurred. Amortization is recognized in expense on a straight-line basis over the estimated useful lives of intangible assets from the date that
they are available for use, since this most closely reflects the expected pattern of consumption of the future economic benefits embodied in the assets.

(g) Research and development:

Expenditures on research activities, undertaken with the prospect of gaining new scientific or technical knowledge and understanding, are recognized in profit or loss
as incurred.

Development activities involve a plan or design for the production of new or substantially improved products or processes. Development expenditures are capitalized
only if development costs can be measured reliably, the product or process is technically and commercially feasible, future economic benefits are probable, and the
Company intends to and has sufficient resources to complete development and to use or sell the asset.

3.

Significant accounting policies (continued):

The Company has not capitalized any development costs to date.

(h)

Investment tax credits:

Research  and  development  investment  tax  credits,  which  are  earned  as  a  result  of  incurring  qualifying  research  and  development  expenditures,  are  recorded  as  a
reduction of the related expense or cost of the asset acquired when there is reasonable assurance that they will be realized.

The Company's claim for scientific research and experimental development ("SR&ED") deductions and related investment tax credits for income tax purposes are
based on management's interpretation of the applicable legislation in the Income Tax Act (Canada). These amounts are subject to review and acceptance by the Canada
Revenue Agency prior to collection.

(i) Employee benefits:

(i) Short-term employee benefits:

Short-term employee benefit obligations are measured on an undiscounted basis and are expensed as the related service is provided.

A liability is recognized for the amount expected to be paid in short-term cash bonuses if the Company expects to pay these amounts as approved by the Board of
Directors as a result of past services provided by the employee and the obligation can be estimated reliably.

(ii) Stock-based compensation:

The Company has a stock-based compensation plan (the "Plan") available to officers, directors, employees and consultants with grants under the Plan approved by the
Company's Board of Directors. Under the Plan, the exercise price of each option equals the closing trading price of the Company's stock on the day prior to the grant if
the grant is made during the trading day or the closing trading price on the day of grant if the grant is issued after markets have closed. Vesting is provided for at the
discretion of the Board of Directors and the expiration of options is to be no greater than 10 years from the date of grant.

The Company uses the fair value based method of accounting for employee awards granted under the Plan. The Company calculates the fair value of each stock option
grant using the Black-Scholes option pricing model at the grant date. The stock-based compensation cost of the options is recognized as stock-based compensation
expense over the relevant vesting period of the stock options using an estimate of the number of options that will eventually vest.

3.

Significant accounting policies (continued):

Stock options awarded to non-employees are accounted for at the fair value of the goods received or the services rendered. The fair value is measured at the date the
Company obtains the goods or the date the counterparty renders the service. If the fair value of the goods or services cannot be reliably measured, the fair value of the
options granted will be used.

(j) Loss per share:

Basic loss per share is computed by dividing the net loss available to common shareholders by the weighted average number of shares outstanding during the year.
Diluted loss per share is computed similarly to basic loss per share except that the weighted average shares outstanding is increased to include additional shares for the
assumed exercise of stock options and warrants, if dilutive. The number of additional shares is calculated by assuming that outstanding stock options and warrants
were  exercised  and  that  the  proceeds  from  such  exercises  were  used  to  acquire  common  stock  at  the  average  market  price  during  the  year.  The  inclusion  of  the
Company's  stock  options  and  warrants  in  the  computation  of  diluted  loss  per  share  has  an  anti-dilutive  effect  on  the  loss  per  share  and,  therefore,  they  have  been
excluded from the calculation of diluted loss per share.

(k)

Income taxes:

Deferred tax is recognized in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts
used for taxation purposes.

Deferred  tax  is  measured  at  the  tax  rates  that  are  expected  to  be  applied  to  temporary  differences  when  they  reverse,  based  on  the  laws  that  have  been  enacted  or
substantively enacted by the reporting date. A deferred tax asset is recognized for unused tax losses, tax credits and deductible temporary differences, to the extent that
it is probable that future taxable profits will be available against which they can be utilized.

(l) Provisions:

A provision is recognized if, as a result of a past event, the Company has a present legal or constructive obligation that can be estimated reliably, and it is probable that
an outflow of economic benefits will be required to settle the obligation. Provisions are determined by discounting the expected future cash flows 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 as a finance cost.

Significant accounting policies (continued):

(m) Finance income and finance costs:

Finance income comprises interest income on funds invested. Interest income is recognized as it accrues in profit or loss using the effective interest method.

Finance costs comprise interest expense on borrowings and are recognized in profit or loss using the effective interest method.

(n) Standards and interpretations adopted in the year ended December 31, 2016:

Effective January 1, 2016, the Company adopted the amendments to IAS1 Presentation of Financial Statements issued by the IASB in December 2014. The impact of
adoption of these amendments did not to have a material impact on the financial statements.

(o) Recent accounting pronouncements:

(i) IFRS 9, Financial Instruments ("IFRS 9"):

IFRS  9  (2014)  introduces  new  requirements  for  the  classification  and  measurement  of  financial  assets.  Under  IFRS  9  (2014),  financial  assets  are  classified  and
measured  based  on  the  business  model  in  which  they  are  held  and  the  characteristics  of  their  contractual  cash  flows.  The  standard  introduces  additional  changes
relating to financial liabilities and also amends the impairment model by introducing a new ‘expected credit loss’ model for calculating impairment. IFRS 9 (2014)
also includes a new general hedge accounting standard which aligns hedge accounting more closely with risk management. The Company intends to adopt IFRS 9
(2014) in its consolidated financial statements for the annual period beginning on January 1, 2018. The extent of the impact of adoption of the standard has not yet
been determined.

(ii) IFRS 16, Leases (“IFRS 16”)

On January 13, 2016, the IASB issued IFRS 16 Leases. The new standard is effective for annual periods beginning on or after January 1, 2019. Earlier application is
permitted for entities that apply IFRS 15 Revenue from Contracts with Customers at or before the date of initial adoption of IFRS 16. IFRS 16 will replace IAS 17
Leases. This standard introduces a single lessee accounting model and requires a lessee to recognize assets and liabilities for all leases with a term of more than 12
months, unless the underlying asset is of low value. The extent of the impact of adoption of the standard has not yet been determined.

Significant accounting policies (continued):

On January 19, 2016 the IASB issued Recognition of Deferred Tax Assets for Unrealized Losses (Amendments to IAS 12). The amendments apply retrospectively
for  annual  periods  beginning  on  or  after  January  1,  2017.  Earlier  application  is  permitted.  The  extent  of  the  impact  of  adoption  of  the  standard  has  not  yet  been
determined.

Capital disclosures:

The Company's objectives when managing capital are to:

· Maintain its ability to continue as a going concern;

· Maintain a flexible capital structure which optimizes the cost of capital at acceptable risk; and

·

Ensure  sufficient  cash  resources  to  fund  its  research  and  development  activity,  to  pursue  partnership  and  collaboration  opportunities  and  to  maintain  ongoing
operations.

The  capital  structure  of  the  Company  consists  of  equity  comprised  of  share  capital,  stock  options,  contributed  surplus  and  deficit.  The  Company  manages  its  capital
structure and makes adjustments to it in light of economic conditions. The Company, upon approval from its Board of Directors, will balance its overall capital structure
through new share issuances, acquiring or disposing of assets, adjusting the amount of cash balances or by undertaking other activities as deemed appropriate under the
specific circumstances.

In  December  2014, Aptose  filed  a  short  form  base  shelf  prospectus  (the  “Base  Shelf”)  that  qualifies  for  the  distribution  of  up  to  US$100,000,000  of  common  shares,
warrants, or units comprising any combination of common shares and warrants (“Securities”). The distribution of Securities may be effected from time to time in one or
more transactions at a fixed price or prices, which may be changed, at market prices prevailing at the time of sale, or at prices related to such prevailing market prices to be
negotiated  with  purchasers  and  as  set  forth  in  an  accompanying  prospectus  supplement,  including  transactions  that  are  deemed  to  be  “at-the-market”  distributions.  The
Base Shelf provides the Company with additional flexibility when managing cash resources as, under certain circumstances, it shortens the time period required to close a
financing and is expected to increase the number of potential investors that may be prepared to invest in our Company. Funds received from a Prospectus Supplement will
be used in line with our Board approved budget and multi-year plan. The Base Shelf expires in December, 2017. The Base Shelf allowed the Company to enter into an “At-
The-Market” Facility (“ATM”) equity distribution agreement (see Note 9). Aptose intends to use this equity arrangement as an additional option to assist in achieving the
Company’s capital objectives. The ATM provides the Company with the opportunity to regularly raise capital on the Nasdaq Capital Market, at prevailing market prices, at
its sole discretion providing the ability to better manage cash resources.

Convertible promissory notes payable:

In  September  2013,  the  Company  completed  a  private  placement  of  convertible  promissory  notes  for  aggregate  gross  proceeds  of  $600  thousand.  Each  convertible
promissory note consisted of a $1 thousand principal amount of unsecured promissory note convertible into common shares of the Company at a price per share of $3.60.
The promissory notes bore interest at a rate of 10% per annum, payable quarterly and were due September 26, 2015.

The promissory notes were a compound financial instrument containing a liability component and an equity component represented by the conversion feature. The fair
value of the liability component upon issuance was estimated by discounting the future cash flows associated with the debt at a discounted rate of approximately 19%
which represented the estimated borrowing cost to the Company for similar promissory notes with no conversion feature. The residual value of $88 thousand was allocated
to the conversion feature.

Subsequent  to  initial  recognition,  the  promissory  notes  were  accounted  for  at  amortized  cost  using  the  effective  interest  rate  method.  The  Company  incurred  costs
associated with the financing of $17 thousand. These costs along with the adjustment for the conversion feature were being accreted using the effective interest rate method
over the 24 month life of the notes.

During the year ended December 31, 2015, all of the outstanding promissory notes were converted into common shares of the Company.

Financial instruments (continued):

(b) Financial risk management:

The Company has exposure to credit risk, liquidity risk, foreign currency risk and market risk. The Company's Board of Directors has the overall responsibility for the
oversight of these risks and reviews the Company's policies on an ongoing basis to ensure that these risks are appropriately managed.

(i) Credit risk:

Credit risk is the risk of financial loss to the Company if a customer, partner or counterparty to a financial instrument fails to meet its contractual obligations, and
arises principally from the Company's cash and cash equivalents. The carrying amount of the financial assets represents the maximum credit exposure.

The  Company  manages  credit  risk  associated  with  its  cash  and  cash  equivalents  by  maintaining  minimum  standards  of  R1-low  or A-low  investments  and  the
Company invests only in highly rated Canadian corporations which are capable of prompt liquidation.

(ii) Liquidity risk:

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they come due. To the extent that the Company does not believe it
has  sufficient  liquidity  to  meet  its  current  obligations,  management  and  the  Board  consider  securing  additional  funds  through  equity,  debt  or  partnering
transactions. The Company manages its liquidity risk by continuously monitoring forecasts and actual cash flows. All of the Company's financial liabilities are
due within the current operating period.

In managing its liquidity risk, the Company has considered its available cash and cash equivalents and has reprioritized its resources towards the development of
CG 806. This reprioritization has resulted in reduced expected cash outflows for the year ending December 31, 2017 relative to what was forecast as of September
30, 2016. The Company has also considered additional cash raised through its At-The-Market (“ATM”) facility of $US 3.7M since December 31, 2016 (see note
18) and its ability to continue to raise funds under this facility in 2017 in assessing whether it will have sufficient resources to fund research and development
operations through to at least the year ending December 31, 2017.

After considering the above factors, management have concluded that there are no material uncertainties related to events or conditions that may cast substantial
doubt  upon  the  Company’s  ability  to  continue  as  a  going  concern.  However,  the  estimates  made  by  management  in  reaching  this  conclusion  are  based  on
information available as of the date these financial statements were authorized for issuance. Accordingly, actual experience will differ from those estimates and
the variation may be material.

Financial instruments (continued):

(iii) Market risk:

Market risk is the risk that changes in market prices, such as interest rates, foreign exchange rates and equity prices will affect the Company's income or the value
of its financial instruments.

The Company is subject to interest rate risk on its cash and cash equivalents and investments. The Company does not believe that the results of operations or cash
flows would be affected to any significant degree by a sudden change in market interest rates relative to interest rates on the investments, owing to the relative
short-term nature of the investments. The Company does not have any interest bearing liabilities subject to interest rate fluctuations.

(iv) Currency risk:

Currency risk is the risk that future cash flows of a financial instrument will fluctuate because of changes in foreign exchange rates. We are exposed to currency
risk  from  employee  costs  as  well  as  the  purchase  of  goods  and  services  primarily  in  the  United  States  and  the  cash  balances  held  in  foreign  currencies.
Fluctuations  in  the  US  dollar  exchange  rate  could  have  a  significant  impact  on  the  Company’s  results. Assuming  all  other  variables  remain  constant,  a  10%
depreciation or appreciation of the Canadian dollar against the US dollar would result in an increase or decrease in loss for the year and comprehensive loss of
$638 thousand (December 31, 2015 - $576 thousand, December 31, 2014 - $50 thousand). Balances in foreign currencies are as follows:

(in thousands) 2016

The Company does not have any forward exchange contracts to hedge this risk.

The Company does not invest in equity instruments of other corporations.

Share capital (continued):

Share consolidation:

In accordance with the authority granted by shareholders at the Company's annual and special meeting on August 19, 2014 to permit it to implement a consolidation of the
Company's  outstanding  common  shares  in  a  ratio  of  between  1-for-5  and  1-for-15,  the  Company's  Board  of  Directors  approved  a  1-for-12  share  consolidation  which
became effective October 1, 2014. The share consolidation affected all of the Company's common shares, stock options and warrants outstanding at the effective time.
Fractional shares were not issued. Prior to consolidation the Company had approximately 139 million shares outstanding. Following the share consolidation, the Company
has approximately 11.6 million common shares outstanding. Similarly, prior to consolidation, the Company had approximately 17.1 million stock options and 2.6 million
warrants  to  purchase  common  shares  outstanding.  Following  the  share  consolidation,  the  Company  had  approximately  1.4  million  stock  options  and  218  thousand
warrants to purchase common shares outstanding. In these consolidated financial statements, all references to number of shares, stock options and warrants in the current
and  past  periods  have  been  adjusted  to  reflect  the  impact  of  the  share  consolidation. All  amounts  based  on  the  number  of  shares,  stock  options  or  warrants,  unless
otherwise specified, such as earnings (loss) per share and weighted average issuance price in the case of stock options have been adjusted to reflect the impact of 1-for-12
share consolidation.

(b) Equity issuances:

At-The-Market (“ATM”) Facility

On April 2, 2015, Aptose entered into an ATM equity facility with Cowen and Company, LLC, acting as sole agent. Under the terms of this facility, Aptose may, from
time to time, sell shares of our common stock having an aggregate offering value of up to US$20 million through Cowen and Company, LLC on the Nasdaq Capital
Market. The Company determines, at our sole discretion, the timing and number of shares to be sold under this ATM facility.

During  the  year  ended  December  31,  2016,  the  Company  issued  3,673,933  common  shares  under  the ATM  at  a  price  of  US$1.65  per  share  for  gross  proceeds  of
USD$6.06 million or CDN$7.97 million. Costs associated with the proceeds included a 3% cash commission as well as legal and accounting fees. The net proceeds
raised year to date total USD$5.69 million or CDN$7.55 million.

(c) Warrants:

There were no warrants exercised during the year ended December 31, 2016. During the year ended December 31, 2016, 73 thousand warrants with an original fair
value of $84 thousand expired unexercised. The original fair value amount was transferred from warrants to contributed surplus.

Commitments, contingencies and guarantees (continued):

(b) Other contractual commitments:

The Company has entered into various contracts with service providers with respect to the clinical development of APTO-253 and for its research program for its new
program CG’806. These contracts will result in future payments commitments of up to $430 thousand.

The Company enters into research, development and license agreements in the ordinary course of business where the Company receives research services and rights to
proprietary  technologies.  Milestone  and  royalty  payments  that  may  become  due  under  various  agreements  are  dependent  on,  among  other  factors,  clinical  trials,
regulatory  approvals  and  ultimately  the  successful  development  of  a  new  drug,  the  outcome  and  timing  of  which  is  uncertain.  Under  the  license  agreement  with
CrystalGenomics,  the  Company  has  future  contingent  milestones  obligations  relating  to  filing  of  an  Investigational  New  Drug  (“IND”)  of  US$2.0  million,
development milestones on the initiation of Phase 2 and pivotal clinical trial of US$16 million, and regulatory milestones totalling US$44 million. In addition, the
Company  also  has  an  obligation  to  pay  royalty  payments  on  sales  of  commercialized  product.  The  company  does  not  anticipate  making  any  payments  under  this
license agreement in 2017.

(c) Guarantees:

The Company entered into various contracts, whereby contractors perform certain services for the Company. The Company indemnifies the contractors against costs,
charges and expenses in respect of legal actions or proceedings against the contractors in their capacity of servicing the Company. The maximum amounts payable
from these guarantees cannot be reasonably estimated. Historically, the Company has not made significant payments related to these guarantees.

The Company indemnifies its directors and officers against any and all claims or losses reasonably incurred in the performance of their service to the Company to the
extent  permitted  by  law.  The  Company  has  acquired  and  maintains  liability  insurance  for  its  directors  and  officers.  The  fair  value  of  this  indemnification  is  not
determinable.

CORPORATE UPDATE

The following items highlight our corporate activities during the year ended December 31, 2016 and any subsequent development up until the date hereof.

PROGRAM UPDATES

APTO-253

Phase Ib Trial

APTO-253 is being evaluated by Aptose in a Phase 1b clinical trial in patients with relapsed / refractory hematologic malignancies.  For the study, a modified dose schedule was
selected, such that APTO-253 is being administered on the first two days of each 7-day dosing period of a 28-day cycle (i.e., days 1, 2, 8, 9, 15, 16, 22, 23). This resulted in
lower  per-administration  dose  levels  to  provide  the  same  overall  exposure  per  cycle  achieved  in  the  prior  Phase  1  solid  tumor  study,  and  to  more  consistently  achieve  the
minimum exposure levels at the end of each dosing period that may be important for efficacy.

The Phase 1b study was originally designed for approximately 15 patients to be enrolled in each of two arms of the dose escalation phase of the study: arm (A) was to include
patients  with  acute  leukemias  (including  acute  myeloid  leukemia  (“AML”))  and  high-risk  myelodysplastic  syndromes  (“MDS”);  arm  (B)  was  to  include  patients  with
lymphomas (Hodgkin’s and non-Hodgkin’s Lymphoma) and multiple myeloma, followed by enrollment of an additional fifteen (15) patients in each of two separate disease-
specific expansion cohorts, for a total estimated enrollment of 60 patients.

Aptose modified the clinical trial design for the Phase 1b study, pending submission and review from regulatory authorities (Institutional Review Boards (“IRB”) & the Food
and Drug Administration (“FDA”), in order to focus all resources on the patient population most likely to benefit from APTO-253.  Under the proposed modification, arm B of
the dose-escalation phase of the study, as described above, will be discontinued.  Arm A of the study, focused on patients with acute leukemias (particularly AML) and MDS
remains unchanged.

Upon completion of the dose-escalation stage of the study and determination of the appropriate dose, the study would enroll hematologic cancer indications selected from the
groups that will be studied in the dose-escalation phase, for enrollment in up to two planned disease-specific single-agent expansion cohorts.

For future development, upon selection of a lead hematologic indication from this Phase 1b study, combination of APTO-253 with a standard therapy would be considered.

Clinical Hold and Current Status
We announced in November 2015 that the FDA, following a voluntary suspension of dosing by Aptose and discussions with us, placed our Phase Ib clinical trial of APTO-253
in patients with hematologic cancers on clinical hold. This hold was intended to evaluate the administration methods within the trial and to ensure manufacturing and dosing
procedures are consistent with FDA guidance and the Code of Federal Regulations.

The voluntary suspension of dosing by Aptose, followed by a clinical hold by the FDA, was initiated to evaluate manufacturing processes and procedures upon the report of an
operational difficulty with an IV infusion pump at a clinical site. During dosing of a patient with 100 mg/m2 dose, the clinical site experienced an infusion pump stoppage,
caused by backflow pressure as a result of clogging of the in-line filter used during the infusion. A safety review of the relevant safety data had been completed prior to initial
discovery  of  the  manufacturing  irregularities,  and  there  have  been  no  drug-related  serious  adverse  events  (“SAEs”)  reported.  The  observed  pharmacokinetic  levels  in  the
patients treated were within the expected range. Thus, the clinical hold is based solely on the operation of the administration of the subject infusion at the clinical site which is
related to a product chemistry issue and has not shown to be related to safety, efficacy or pharmacokinetic profile of the molecule.

We have worked with a chemistry-focused Contract Manufacturing Organization (“CMO”) and determined that the root cause of the filter clogging event with the prior drug
product was chemistry-based. Likewise, we guided a qualified CMO to introduce new methodologies to formulate APTO-253 into a drug product that is safe and stable, and
which  should  not  result  in  filter  clogging  events  in  the  future.  Good  Manufacturing  Practice  (“GMP”)  batches  of  the Active  Pharmaceutical  Ingredient  (“API”)  have  been
manufactured to provide material for formulation studies and to supply the clinical drug product into the future. Based on numerous formulation studies conducted by a CMO
with expertise in formulation development, a new soluble and stable formulation for the drug product has been selected. In parallel with these studies, mock infusion studies
using the newly formulated prototype drug product demonstrated no filter clogging, and supplementary mock infusion studies were performed at multiple CROs to ensure the
durability and solubility of the new formulation to be used in the infusion process/filter clogging that caused the clinical hold. In order to respond to the FDA’s inquiry on the
filter clogging issue which could result in the clinical hold being removed, Aptose must articulate the root cause of the filter clogging incident to the FDA and demonstrate to the
FDA that a newly manufactured batch of GMP-grade APTO-253 drug substance and drug product has been formulated and should not cause such incidents in the future. On
September 12, 2016, we submitted a formal response to the FDA regarding the clinical hold of our Phase 1b clinical trial of APTO-253 in patients with hematologic cancers.

3

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
On October 12, 2016, we received a response from the FDA informing us that the clinical hold would remain in place until Aptose provides to the FDA the standard chemistry,
manufacturing and control (“CMC”) information on the final GMP drug substance and drug product that will be manufactured for the clinic. Data provided to the FDA in our
response to the clinical hold questions were collected using prototype batches of API and drug product. As the drug substance was changed from a salt to a free base, and the
proportions of the original excipients were modified in the drug product formulation, the FDA has requested additional information on the GMP-grade drug substance and drug
product that is will be manufactured for use in the clinic prior to making a decision on the hold and approval for the re-initiation of the clinical trial.

We believe we have now developed a drug product that does not cause filter clogging or pump stoppage during simulated infusion studies. The new formulation of APTO-253
offers  the  potential  for  improved  handling  characteristics  for  administration  by  infusion  and  the  potential  for  creating  new  intellectual  property.  However  there  can  be  no
assurance that the FDA will remove the clinical, hold which could cause additional development costs to the Company.

On December 29, 2016, we announced that we had successfully manufactured multiple non-GMP batches of a new drug product formulation for APTO-253, including a batch
that had been stable and soluble for over six months. However, we also announced that we would have to repeat the production of the fourth batch, a 40L batch that was the
intended clinical supply because of a potential engineering design incompatibility that occurred during the filling process. At that time, we believed that the root cause of the
drug product stability failure and a corrective action (“CAPA”) could be determined rapidly and that another manufacturing campaign to produce a GMP grade clinical supply
could be initiated in January 2017.

On January 23, 2017, we announced that the root cause and CAPA studies would take longer than originally expected and that we would temporarily delay clinical activities
with APTO-253 in order to elucidate the cause of recent manufacturing setbacks related to the intravenous formulation of APTO-253 with the intention of restoring the molecule
to a state supporting clinical development and partnering.

CG’806
In June 2016, Aptose announced a definitive agreement with South Korean company CrystalGenomics, Inc. (“CG”), granting Aptose an exclusive option to research, develop
and commercialize CG026806 (“CG’806”) in all countries of the world except Korea and China, for all fields of use. CG’806 is a highly potent, non-covalent small molecule
therapeutic  agent.  This  multi-kinase  inhibitor  exhibits  a  picomolar  IC50  toward  the  FMS-like  tyrosine  kinase  3  with  the  Internal  Tandem  Duplication  (“FLT3-ITD”)  and
potency against a host of mutant forms of FLT3, as well as single-digit nanomolar IC50’s against Bruton’s tyrosine kinase (“BTK”) and its C481S mutant (“BTK-C481S”).
Further, CG’806 is a multi-targeted BTK / FLT3-ITD inhibitor, as it impacts other relevant oncogenic targets, including the Aurora kinases (AURK), RET, MET, DDR2, and
SRC kinases.

Aptose paid US$1.0 million (CA$1.294 million) (the “Option Grant Fee”) to CG to acquire the option. Should we elect to exercise the option prior to the earlier of (i) filing of
an Investigational New Drug (“IND”) application with the FDA, (ii) first dosage of a human in a clinical trial, (iii) payment of the Option Exercise Fee or (iii) twenty-four (24)
months after the payment of the Option Grant Fee, we would pay an additional US$2.0 million (the “Option Exercise Fee”) in cash or combination of cash and common shares,
and would receive full development and commercial rights for the program in all territories outside of the Republic of Korea and China. The agreement can only be terminated
by Aptose without cause or by both parties in the event of a material breach.

As  a  potent  inhibitor  of  FLT3-ITD,  CG’806  may  become  an  effective  therapy  in  this  subset  of AML  patients,  as  the  FLT3-ITD  mutation  occurs  in  approximately  30%  of
patients with AML. Importantly, CG’806 targets other oncogenic kinases which may also be operative in FLT3-ITD AML, including RET and SRC family kinases, thereby
potentially allowing the agent to become an important therapeutic option for this difficult-to-treat patient population.

The  C481S  mutation  of  BTK  arises  from  therapy  with  covalent,  irreversible  BTK  inhibitors  that  target  the  active  site  Cysteine  (“Cys”)  residue  of  BTK,  thereby  conferring
resistance  to  other  covalent  BTK  inhibitors. As  a  non-covalent,  reversible  inhibitor,  CG’806  does  not  rely  on  the  Cysteine  481  residue  for  inhibition  of  the  BTK  enzyme.
Consequently, patients relapsed, refractory or intolerant to other commercially approved or development stage BTK inhibitors with chronic lymphocytic leukemia (“CLL”) or
mantle cell lymphoma (“MCL”) may continue to be sensitive to CG’806 therapy.

CG’806  is  currently  in  route  scouting  studies  to  select  an  appropriate  synthetic  pathway  to  manufacture  the  molecule,  in  formulation  development  studies,  and  in  various
preclinical biological pathway and animal efficacy studies. Provided the studies continue on the anticipated timeline, Aptose expects to file an IND application for a first-in-
human clinical trial in late 2017 or early 2018. CG’806 is being developed with the intent to deliver the agent as a once-daily, oral therapeutic.

Multi-Targeting Bromodomain Program
In November 2015, Aptose entered into a definitive agreement with Moffitt Cancer Center for exclusive global rights to potent, dual-targeting, single-agent inhibitors for the
treatment  of  hematologic  and  solid  tumor  cancers.  These  small  molecule  agents  are  highly  differentiated  inhibitors  of  the  Bromodomain  and  Extra-Terminal  motif  (“BET”)
protein family members, which simultaneously target specific kinase enzymes. The molecules developed by Moffitt were reported to exhibit potency against the BET family
members, including bromodomain 4 (“BRD4”), and specific oncogenic kinases which, when inhibited, are synergistic with BET inhibition. Under the agreement, Aptose has
access to the drug candidates developed by Moffitt and the underlying intellectual property covering certain chemical modifications enabling bromodomain (“BRD”) inhibition
on the chemical backbone of a kinase inhibitor.

In January 2017, Aptose terminated the collaboration with Moffitt Cancer Center for the development of the dual BRD4 / JAK2 inhibitor program.

Multi-Targeting Epigenetic Program
In  November  2015, Aptose  also  announced  an  exclusive  drug  discovery  partnership  with  Laxai  Avanti  Life  Sciences  (“LALS”)  for  the  development  of  next  generation
epigenetic-based therapies. Under the agreement, LALS is responsible for optimizing candidates derived from Aptose's relationship with the Moffitt Cancer Center. Aptose will
own global rights to all newly discovered candidates characterized and optimized under the collaboration, including all generated intellectual property. As of November 2016,
Aptose and LALS have generated novel compounds that inhibit both the bromodomain proteins and oncogenic kinases, while improving pharmaceutical properties that could
serve as a basis for further optimization towards a lead preclinical candidate. However, due to a prioritization of development efforts, Aptose and LALS have suspended work on
the program, and the collaboration with LALS has been terminated. However, the program delivered novel IP and hit molecules for further optimization. As a consequence,
Aptose may choose to out-license the program.

FINANCING ACTIVITIES

At-The-Market (“ATM”) Facility

On April 2, 2015, Aptose entered into an at-the-market equity facility (“ATM Facility”) with Cowen and Company, LLC, acting as sole agent. Under the terms of this facility,
Aptose may, from time to time, sell common shares having an aggregate offering value of up to US$20 million through Cowan and Company, LLC. The Company determines,
at its sole discretion, the timing and number of shares to be sold under the ATM Facility.

During the year ended December 31, 2016, the Company issued 3,673,933 common shares through the ATM raising net proceeds of USD$5.69 million or CDN$7.55 million.
Costs associated with the proceeds included a 3% cash commission as well as legal and accounting fees.

Subsequent to the year end, we issued an additional 3,127,836 common shares under the ATM Facility for gross proceeds of US$3.707 million.

April 2014
In April 2014, we completed a public offering of common shares. Aptose issued 4,708,334 (56,500,000 pre-consolidation) common shares at a purchase price of $6.00 ($0.50
pre-consolidation)  per  common  share,  including  541,667  (6,500,000  pre-consolidation)  common  shares  pursuant  to  the  partial  exercise  of  an  over-allotment  option,  for
aggregate gross proceeds of $28.3 million. The total costs associated with the transaction were approximately $2.7 million which includes a cash commission of $2.0 million
based on 7% of the gross proceeds received as part of the offering.

December 2013
In December 2013, Aptose completed a public offering of common shares. Aptose issued 1,060,833 (pre-consolidation 12,730,000) common shares at a price of $6.60 (pre-
consolidation $0.55) per common share and an additional 159,125 (pre-consolidation 1,909,500) common shares upon the exercise of the overallotment option for aggregate
gross proceeds of $8.1 million.

The total costs associated with the transaction were approximately $1.1 million which include a cash commission of $483 thousand based on 6% of the gross proceeds received
as part of the offering, and the issuance of 73,198 (pre-consolidation 878,370) broker warrants with an estimated fair value of $350 thousand. The fair value of these warrants
was determined using the Black Scholes model with a 24 month time to maturity, an assumed volatility of 130% and a risk free interest rate of 1.5%. Each broker warrant was
exercisable into one common share of the Company at a price of $6.60 (pre-consolidation $0.55) for a period of twenty four months following closing of the offering.

WARRANT EXERCISES

During the year ended December 31, 2015, 81,000 Common Share purchase warrants were exercised for proceeds of $348,000. During the seven months ended December 31,
2014, 1,231,000 Common Share purchase warrants were exercised for proceeds of $6,648,000. During the year ended December 31, 2016 the remaining warrants from a 2011
financing expired. As at December 31, 2016 there are no outstanding warrants.

LIQUIDITY AND CAPITAL RESOURCES

Since its inception, Aptose has financed its operations and technology acquisitions primarily from equity and debt financing, proceeds from the exercise of warrants and stock
options, and interest income on funds held for future investment.

We currently do not earn any revenues from our drug candidates and are therefore considered to be in the development stage. The continuation of our research and development
activities and the commercialization of the targeted therapeutic products are dependent upon our  ability  to  successfully  finance  and  complete  our  research  and  development
programs through a combination of equity financing and payments from strategic partners. We have no current sources of significant payments from strategic partners.

In managing its liquidity risk, the Company has considered its available cash and cash equivalents and has reprioritized its resources towards the development of CG 806. This
reprioritization has resulted in reduced expected cash outflows for the year ending December 31, 2017 relative to what was forecast as of September 30, 2016. The Company
has also considered additional cash raised through its At-The-Market (“ATM”) facility of $US 3.7M since December 31, 2016 and its ability to continue to raise funds under
this facility in 2017 in assessing whether it will have sufficient resources to fund research and development operations through to at least the year ending December 31, 2017.

After considering the above factors, management have concluded that there are no material uncertainties related to events or conditions that may cast substantial doubt upon the
Company’s ability to continue as a going concern. However, the estimates made by management in reaching this conclusion are based on information available as of the date
this report was authorized for issuance. Accordingly, actual experience will differ from those estimates and the variation may be material.

CASH POSITION

At December 31, 2016, we had cash and cash equivalents of $10.7 million compared to cash and cash equivalents and investments of $19.7 million at December 31, 2015. We
generally invest our cash in excess of current operational requirements in highly rated and liquid instruments. Investment decisions are made in accordance with an established
investment policy administered by senior management and overseen by our Audit Committee and Board of Directors. As at December 31, 2016, our cash and cash equivalents
consisted of cash of $3.9 million (December 31, 2015 - $761 thousand) and in funds deposited into high interest savings accounts in both Canadian and US funds totaling $6.7
million  (December  31,  2015  -  $10.7  million).  Working  capital  (representing  primarily  cash,  cash  equivalents,  investments  and  other  current  assets  less  current  liabilities)  at
December 31, 2016 was $9.6 million (December 31, 2015 –$18.5 million). Total assets as of December 31, 2016 total $11.6 million (December 31, 2015 - $21.2 million).

We do not expect to generate positive cash flow from operations for the foreseeable future due to additional research and development costs, including costs related to drug
discovery, preclinical testing, clinical trials, manufacturing costs and operating expenses associated with supporting these activities. It is expected that negative cash flow will
continue until such time, if ever, that we receive regulatory approval to commercialize any of our products under development and/or royalty or milestone revenue from any
such products exceeds expenses.

RESULTS OF OPERATIONS

Our net loss for the year ended December 31, 2016 was $18.6 million ($1.46 per share) compared with $14.6 million ($1.23 per share) during the year ended December 31,
2015 and with a loss of $7.8 million ($0.67 per share) in the seven months ended December 31, 2014.

The  increase  in  net  loss  during  the  year  ended  December  31,  2016  compared  with  the  year  ended  December  31,  2015  is  primarily  due  to  higher  research  and  development
activities  related  to  the  $1.294  million  option  fee  for  CG’806,  costs  associated  with APTO-253  and  the  new  Moffitt/LALS  program  as  well  as  additional  headcount  in  the
research and clinical departments to support these activities. In addition, the lower Canadian dollar resulted in an increase in our US dollar denominated costs in comparison
with the prior year. Additionally, we recognized net finance income of $1.5 million in the prior year period mostly due to gains on our US dollar denominated cash and cash
equivalents compared with a net finance income of $39 thousand in the current year period due to interest income net of foreign exchange losses on our US dollar denominated
cash and cash equivalents.

The increase in net loss and comprehensive loss in the year ended December 31, 2015 compared with the seven months ended December 31, 2014 is due to a twelve month
period compared with a seven month period as well as increased research and development costs associated with the APTO-253 Phase Ib clinical trial described above for which
the first patient was enrolled in January 2015. The increased research and development costs were offset by a higher finance income related to foreign currency gains on our
USD cash and cash equivalents balances due to the devaluation of the Canadian dollar.

We utilized cash of $16.4 million in our operating activities in the year ended December 31, 2016 compared with $12.7 million in the year ended December 31, 2015 and $6.7
million in the seven months ended December 31, 2014. The increase in cash utilized in the current year is predominantly due to increased research and development activities

At December 31, 2016, we had cash and cash equivalents of $10.7 million compared to cash and cash equivalents and investments of $19.7 million at December 31, 2015.

Research and Development
Research and development expenses totaled $10.3 million in the year ended December 31, 2016 compared with $6.3 million in the year ended December 31, 2015 and totaled
$2.4 million for the seven months ended December 31, 2014. Research and development costs consist of the following:

Expenditures for the year ended December 31, 2016 increased significantly over the year ended December 31, 2015 due to the following reasons:

·
·

·
·
·

Research and development activities related to the option fee for CG’806;
Costs associated with the LALS/Moffitt collaboration developing epigenetic single molecule inhibitors of multiple targets, including the BET proteins, and other kinases
for which no comparable expenses existed in the prior year periods;
Increased research and clinical operations headcount and related costs;
Formulation and manufacturing costs associated with APTO-253 and the root cause analysis of the filter clogging identified in November 2015; and
Increased Contract Research Organization costs related to consultants and advisors as we work towards returning APTO-253 to the clinic.

During the year ended December 31, 2016, we paid US$1.0 million (CA$1.294 million) to CG for an option fee related to the CG’806 technology. Should we elect to exercise
the  option  prior  to  filing  of  an  IND  application  with  the  FDA,  we  would  pay  an  additional  US$2.0  million  in  cash  or  combination  of  cash  and  common  shares,  and  would
receive full development and commercial rights for the program in all territories outside of Korea and China. No comparable expense existed in the same period in the prior
year.

Expenditures for the year ended December 31, 2015 increased significantly over the seven months ended December 31, 2014 (on an annualized basis) due to the following:

·

·
·
·
·

Costs associated with the Phase 1b clinical trial of APTO-253 in patients with relapsed or refractory hematologic malignancies including clinical site costs, patient costs,
contract research organization and consulting charges. The first patient in the trial was enrolled in January 2015;
Development costs related to the Moffitt/LALS programs which were initiated in the fourth quarter of 2015;
Formulation, manufacturing and compliance costs related to the development of APTO-253 including costs related to the clinical hold described above;
Additional payroll related costs in the clinical department due to restructuring to support ongoing activities; and
The increased cost of US dollar denominated expenditures due to the devaluation of the CDN dollar in 2015.

Stock-based compensation costs allocated to research and development increased in the year ended December 31, 2016 compared with the year ended December 31, 2015 to
reflect option grants to new employees hired in the second half of 2015 as the expense related to those grants was amortized 50% in the first 12 months.

Stock-based compensation expense increased in the year ended December 31, 2015 compared with the seven months ended December 31, 2014 primarily due to option grants to
new employees and advisors during the year.

General and Administrative
General and administrative expenses totaled $8.3 million in the year ended December 31, 2016 compared to $9.8 million in the year ended December 31, 2015 and $5.5 million
in the seven months ended December 31, 2014.

General and administrative expenses excluding salaries, decreased in the year ended December 31, 2016 compared with the year ended December 31, 2015. The decrease is the
result of lower travel, consulting and legal costs in the current year related to transactions completed in the prior year as well as lower press release and filing costs associated
with a lower cost service provider in the current year periods.

Salary charges in the year ended December 31, 2016 increased in comparison with the year ended December 31, 2015 due to additional headcount in the first half of 2016
compared with the first half of 2015 as well as a higher average CA/US exchange rate which increased the cost of our US denominated salaries in the first six months of 2016 in
comparison with the prior year, and higher bonus expense recognized in the current period.

Stock-based compensation decreased in the year ended December 31, 2016 compared with the year ended December 31, 2015 due to large option grants in April, June and July
2014 which vested 50% during the first year and therefore contribute to higher stock-based compensation expense during the first twelve month period captured in the prior year
period.

Stock-based compensation expense increased in the year ended December 31, 2015 compared with the seven months ended December 31, 2014 primarily due to option grants to
new employees and advisors during the year.

Finance Expense
For the year ended December 31, 2016, finance expense totaled $66 thousand compared with $43 thousand for the same period in the prior year. Finance expense includes the
following items:

Interest expense
Accretion expense
Foreign exchange loss on cash and cash equivalents

described above. There were no interest-bearing liabilities outstanding at December 31, 2015. Foreign exchange loss is the result of the fluctuation of exchange rates between
US and Canadian dollars and the impact on our US dollar denominated cash balances.

For the reasons discussed above, our net loss for the year ended December 31, 2016 increased to $18.6 million ($1.46 per share) compared to $14.6 million ($1.23 per share) in
the year ended December 31, 2015.

Research and development expenditures increased in the three months ended June 30, 2016 due to the $1.294 million option fee paid to CG as previously described herein.
Research and development expenses increased in the quarters ended December 31, 2016, September 30, 2016, March 31, 2016 and December 31, 2015 in comparison to the
prior year quarters due to the Phase 1b clinical trial of APTO-253 for which the first patient was enrolled in January 2015 and was subsequently placed on hold in November
2015,  and  the  costs  associated  with  the  quality,  manufacturing  and  formulation  work  including  the  clinical  hold  previously  described  herein  as  well  as  costs  related  to  the
collaboration agreement with Moffitt and LALS.

General  and  administrative  costs  increased  in  the  three  months  ended  March  31,  2016  due  to  our  US  dollar  expenses  and  payroll  costs  which  were  more  costly  due  to  the
devaluation of the Canadian dollar over that time period. The decrease in general and administrative costs in the three months ended September 30, 2016 and December 31,
2016 is primarily due to lower stock based compensation expense and the completion of certain projects.

Cash  used  in  operating  activities  fluctuates  significantly  due  primarily  to  timing  of  payments  and  increases  and  decreases  in  the  accounts  payables  and  accrued  liabilities
balances.

Our net loss for the three months ended December 31, 2016 was $3.9 million ($0.26 per share) compared with $4.4 million ($0.38 per share) in the same period in the prior year.

Research  and  development  costs  increased  to  $2.6  million  in  the  three  months  ended  December  31,  2016  compared  with  $2.3  million  incurred  in  the  three  months  ended
December 2015. The Company incurred higher costs for formulation studies and manufacturing costs for the APTO-253 product in the three months ended December 31, 2016
than in the comparable period, and these were offset by lower expenses for the contract research organization costs to manage the study. In addition, in the current period the
Company was conducting studies related to its CG’806 program following the licensing of the technology in June 2016.

General and administrative expenses decreased to $1.5 million in the three months ended December 31, 2016 compared with $2.4 million in the three months ended December
31, 2015. The decrease despite the increased cost of our US dollar expenditures due to the devaluation of the Canadian dollar is related to lower stock option compensation and
lower consulting fees related to projects that were active and completed in the prior quarter.

USE OF PROCEEDS

CRITICAL ACCOUNTING POLICIES

Critical Accounting Policies and Estimates
We periodically review our financial reporting and disclosure practices and accounting policies to ensure that they provide accurate and transparent information relative to the
current  economic  and  business  environment. As  part  of  this  process, Aptose  has  reviewed  its  selection,  application  and  communication  of  critical  accounting  policies  and
financial disclosures. Management has discussed the development and selection of the critical accounting policies with the Audit Committee of the Board of Directors and the
Audit Committee has reviewed the disclosure relating to critical accounting policies in this MD&A. Other important accounting policies are described in note 3 of the audited
financial statements.

Management’s assessment of the Company’s ability to continue as a going concern involves making a judgment, at a particular point in time, about inherently uncertain future
outcomes and events or conditions. Please see the “Liquidity  and  Capital  Resources”  section  in  this  document  for  a  discussion  of  the  factors  considered  by  management  in
arriving at its assessment.

(a) Valuation of stock-based compensation and share purchase warrants:
Management measures the costs for stock-based payments and share purchase warrants using market-based option valuation techniques. Assumptions are made and judgment is
used in applying valuation techniques. These assumptions and judgments include estimating the future volatility of the share price, expected dividend yield, future employee
turnover rates and future share option and share purchase warrant behaviors and corporate performance. Such judgments and assumptions are inherently uncertain. The increase
or decrease of one of these assumptions could materially increase or decrease the fair value of share-based compensation and share purchase warrants issued and the associated
expense.

(b) Valuation of tax accounts:
Uncertainties exist with respect to the interpretation of complex tax regulations and the amount and timing of future taxable income. Currently, we have deductible temporary
differences which would create a deferred tax asset. Deferred tax assets are recognized for all deductible temporary differences to the extent that it is probable that future taxable
profit will be available against which the deductible temporary differences can be utilized. Management judgment is required to determine the amount of deferred tax assets that
can be recognized, based upon the likely timing and the level of future taxable profits together with future tax planning strategies. To date, we have determined that none of our
deferred tax assets should be recognized. Our deferred tax assets are mainly comprised of our net operating losses from prior years and prior year research and development
expenses. These tax pools relate to entities that have a history of losses, have varying expiry dates, and may not be used to offset taxable income. As well, there are no taxable
temporary differences or any tax planning opportunities available that could partly support the recognition of these losses as deferred tax assets. The generation of future taxable
income could result in the recognition of some portion or all of the remaining benefits, which could result in an improvement in our results of operations through the recovery of
future income taxes.

(c) Valuation of contingent liabilities:
We  utilize  considerable  judgment  in  the  measurement  and  recognition  of  provisions  and  Aptose’s  exposure  to  contingent  liabilities.  Judgment  is  required  to  assess  and
determine the likelihood that any potential or pending litigation or any and all potential claims against us may be successful. We must estimate if an obligation is probable as
well as quantify the possible economic cost of any claim or contingent liability. Such judgments and assumptions are inherently uncertain. The increase or decrease of one of
these assumptions could materially increase or decrease the fair value of the liability and the associated expense.

ACCOUNTING PRONOUNCEMENTS ADOPTED DURING THE YEAR

Amendments to IAS 1
Effective January 1, 2016, the Company adopted the amendments to IAS1 Presentation of Financial Statements issued by the IASB in December 2014. The impact of adoption
of these amendments did not to have a material impact on the financial statements.

RECENT ACCOUNTING PRONOUNCEMENTS NOT YET ADOPTED

IFRS 9, Financial Instruments ("IFRS 9"):
IFRS 9 (2014) introduces new requirements for the classification and measurement of financial assets. Under IFRS 9 (2014), financial assets are classified and measured based
on the business model in which they are held and the characteristics of their contractual cash flows. The standard introduces additional changes relating to financial liabilities
and  also  amends  the  impairment  model  by  introducing  a  new  ‘expected  credit  loss’  model  for  calculating  impairment.  IFRS  9  (2014)  also  includes  a  new  general  hedge
accounting standard which aligns hedge accounting more closely with risk management. The Company intends to adopt IFRS 9 (2014) in its consolidated financial statements
for the annual period beginning on January 1, 2018. The extent of the impact of adoption of the standard has not yet been determined.

12

 
 
 
 
 
 
 
 
 
 
 
 
 
IFRS 16, Leases (“IFRS 16”)
On January 13, 2016, the IASB issued IFRS 16 Leases. The new standard is effective for annual periods beginning on or after January 1, 2019. Earlier application is permitted
for entities that apply IFRS 15 Revenue from Contracts with Customers at or before the date of initial adoption of IFRS 16. IFRS 16 will replace IAS 17 Leases. This standard
introduces a single lessee accounting model and requires a lessee to recognize assets and liabilities for all leases with a term of more than 12 months, unless the underlying asset
is of low value. The extent of the impact of adoption of the standard has not yet been determined.

Recognition of Deferred Tax Assets for Unrealized Losses (Amendments to IAS 12)
On January 19, 2016 the IASB issued Recognition of Deferred Tax Assets for Unrealized Losse (Amendments to IAS 12). The amendments apply retrospectively for annual
periods beginning on or after January 1, 2017. Earlier application is permitted. The extent of the impact of adoption of the standard has not yet been determined.

RELATED PARTY TRANSACTIONS

In  March  2015,  the  Company  entered  into  an  agreement  with  the  Moores  Cancer  Center  at  the  University  of  California  San  Diego  (UCSD)  to  provide  pharmacology  lab
services to the Company. Dr. Stephen Howell is the Acting Chief Medical Officer of Aptose and is also a Professor of Medicine at UCSD and will be overseeing the laboratory
work. The research services will be provided from April 1, 2015 to March 31, 2016 for an annual fee of US$154,456 to be paid to UCSD in monthly installments. This research
services agreement was approved by the Aptose Board of Directors on February 23, 2016 for an additional 12 month period beginning April 1, 2016 and for an annual fee of up
to US$200,000. This transaction is in the normal course of business and will be measured at the amount of consideration established and agreed to by the related parties.

See note 14 to the audited financial statements for disclosures of key management personnel compensation and directors’ compensation.

At December 31, 2016, there are no significant differences between the carrying values of these amounts and their estimated market values due to their short-term nature.

(b) Financial risk management

We have exposure to credit risk, liquidity risk and market risk. Our Board of Directors has the overall responsibility for the oversight of these risks and reviews our
policies on an ongoing basis to ensure that these risks are appropriately managed.

(i) Credit risk

Credit risk is the risk of financial loss to us if a customer, partner or counterparty to a financial instrument fails to meet its contractual obligations, and arises principally
from our cash and cash equivalents and investments. The carrying amount of the financial assets represents the maximum credit exposure.

We manage credit risk for our cash and cash equivalents and investments by maintaining minimum standards of R1-low or A-low investments and we invest only in
highly rated Canadian corporations with debt securities that are traded on active markets and are capable of prompt liquidation.

(ii) Liquidity risk

Liquidity risk is the risk that we will not be able to meet our financial obligations as they come due. To the extent that we do not believe we have sufficient liquidity to
meet  our  current  obligations,  the  Board  considers  securing  additional  funds  through  equity  or  debt  transactions.  We  manage  our  liquidity  risk  by  continuously
monitoring forecasts and actual cash flows. All of our financial liabilities are due within the current operating period.

(iii) Market risk

Market risk is the risk that changes in market prices, such as interest rates, foreign exchange rates and equity prices will affect our income or the value of our financial
instruments.

We are subject to interest rate risk on our cash and cash equivalents however we do not believe that the results of operations or cash flows would be affected to any
significant degree by a sudden change in market interest rates relative to interest rates on the investments, owing to the relative short-term nature of the investments. We
do not have any material interest bearing liabilities subject to interest rate fluctuations.

Currency risk is the risk that future cash flows of a financial instrument will fluctuate because of changes in foreign exchange rates. We are exposed to currency risk
from employee costs as well as the purchase of goods and services primarily in the United States and the cash balances held in foreign currencies. Fluctuations in the US
dollar  exchange  rate  could  potentially  have  a  significant  impact  on  the  Company’s  results.  Assuming  all  other  variables  remain  constant,  a  10%  depreciation  or
appreciation of the Canadian dollar against the US dollar would result in an increase or decrease in loss for the year and comprehensive loss of $638 thousand (December
31, 2015- $576 thousand, December 31, 2014 - $50 thousand). Balances in foreign currencies at December 30, 2016 are as follows:

(in thousands)

Cash and cash equivalents
Accounts payable and accrued liabilities
Balance, end of period

The Company does not have any forward exchange contracts to hedge this risk.

The Company does not invest in equity instruments of other corporations.

Our  primary  objective  when  managing  capital  is  to  ensure  that  we  have  sufficient  cash  resources  to  fund  our  development  activities  and  to  maintain  our  ongoing
operations.  To  secure  the  additional  capital  necessary  to  pursue  these  plans,  we  may  attempt  to  raise  additional  funds  through  the  issuance  of  equity  or  by  securing
strategic partners.

We include cash and cash equivalents and investments in the definition of capital.

We are not subject to externally imposed capital requirements and there has been no change with respect to the overall capital risk management strategy during the year
ended December 31, 2016.

OUTLOOK

Until  one  of  our  drug  candidates  receives  regulatory  approval  and  is  successfully  commercialized, Aptose  will  continue  to  incur  operating  losses.  The  magnitude  of  these
operating losses will be largely affected by the timing and scope of future research and development, clinical trials and the Company’s ability to raise additional and ongoing
working capital and/or establish effective partnerships to share the costs of development and clinical trials.

RISK FACTORS

Investing in our securities involves a high degree of risk. Before making an investment decision with respect to our common shares, you should carefully consider the following
risk  factors,  in  addition  to  the  other  information  included  or  incorporated  by  reference  into  the  most  recently  filed  annual  information  form,  as  well  as  our  historical
consolidated financial statements and related notes. Management has reviewed the operations of the Company in conjunction with the Board of Directors and identified the
following risk factors which are monitored on a bi-annual basis and reviewed with the Board of Directors. The risks set out below are not the only risks we face. If any of the
following risks occur, our business, financial condition, prospects or results of operations and cash flows would likely suffer. In that case, the trading price of our common
shares could decline and you may lose all or part of the money you paid to buy our common shares

We have a history of operating losses. We expect to incur net losses and we may never achieve or maintain profitability.

We have not been profitable since our inception in 1986. We reported net losses of $18.6 million in the fiscal year ended December 31, 2016, $14.6 million in the
fiscal year ended December 31, 2015, and $7.8 million in the 7 months ended December 31, 2014, and as of December 31, 2016, we had an accumulated deficit of $251.5
million.

We have not generated any significant revenue to date and it is possible that we will never have sufficient product sales revenue (if any) to achieve profitability. We
expect to continue to incur losses for at least the next several years as we or our collaborators and licensees pursue clinical trials and research and development efforts. To
become  profitable,  we,  either  alone  or  with  our  collaborators  and  licensees,  must  successfully  develop,  manufacture  and  market  our  current  product  candidates  CG’806  or
APTO-253 as well as continue to identify, develop, manufacture and market new product candidates. It is possible that we will never have significant product sales revenue or
receive royalties on our licensed product candidates. If funding is insufficient at any time in the future, we may not be able to develop or commercialize our products, take
advantage of business opportunities or respond to competitive pressures.

We are an early stage development company.

We are at an early stage of development. In the past five years, none of our potential products has obtained regulatory approval for commercial use and sale in any
country and as such, no significant revenues have resulted from product sales. Significant additional investment will be necessary to complete the development of any of our
product candidates. Preclinical and clinical trial work must be completed before our potential products could be ready for use within the markets that we have identified. We
may  fail  to  develop  any  products,  obtain  regulatory  approvals,  enter  clinical  trials  or  commercialize  any  products.  We  do  not  know  whether  any  of  our  potential  product
development efforts will prove to be effective, meet applicable regulatory standards, obtain the requisite regulatory approvals, be capable of being manufactured at a reasonable
cost  or  be  accepted  in  the  marketplace.  We  also  do  not  know  whether  sales,  license  fees  or  related  royalties  will  allow  us  to  recoup  any  investment  we  make  in  the
commercialization of our products.

The product candidates we are currently developing are not expected to be commercially viable for at least the next several years and we may encounter unforeseen

difficulties or delays in commercializing our product candidates. In addition, our potential products may not be effective or may cause undesirable side effects.

Our  product  candidates  require  significant  funding  to  reach  regulatory  approval  assuming  positive  clinical  results.  For  example,  our  product  candidate APTO-253
began enrolment in a Phase I clinical trial in patients with relapsed or refractory hematologic malignancies and was placed on clinical hold by the United States Food and Drug
Administration (“FDA”) following a voluntary suspension of dosing by us. We are currently delaying the development of APTO-253 but significant additional funding or a
partnership will be necessary to complete, if required, Phase II or Phase III clinical trials. Such funding may be very difficult, or impossible to raise in the public or private
markets or through partnerships. If funding or partnerships are not attainable, the development of these product candidates may be significantly delayed or stopped altogether.
The announcement of a delay or discontinuation of development would likely have a negative impact on our share price.

We need to raise additional capital.

We  have  an  ongoing  need  to  raise  additional  capital.  To  obtain  the  necessary  capital,  we  must  rely  on  some  or  all  of  the  following:  additional  share  issues,  debt
issuances  (including  promissory  notes),  collaboration  agreements  or  corporate  partnerships  and  grants  and  tax  credits  to  provide  full  or  partial  funding  for  our  activities.
Additional funding may not be available on terms that are acceptable to us or in amounts that will enable us to carry out our business plan.

Our need for capital may require us to:

·
·
·

·
·
·

engage in equity financings that could result in significant dilution to existing investors;
delay or reduce the scope of or eliminate one or more of our development programs;
obtain funds through arrangements with collaborators or others that may require us to relinquish rights to technologies, product candidates or products that we
would otherwise seek to develop or commercialize ourselves; or
license rights to technologies, product candidates or products on terms that are less favourable to us than might otherwise be available;
considerably reduce operations; or
cease our operations.

Delays in clinical testing could result in delays in commercializing our product candidates, and our business may be substantially harmed.

We cannot predict whether any clinical trials will begin as planned, will need to be restructured or will be completed on schedule, or at all. Our product development
costs  will  increase  if  we  experience  delays  in  clinical  testing.  Significant  clinical  trial  delays  could  shorten  any  periods  during  which  we  may  have  the  exclusive  right  to
commercialize our product candidates or allow our competitors to bring products to market before us, which would impair our ability to successfully commercialize our product
candidates  and  may  harm  our  financial  condition,  results  of  operations  and  prospects.  The  commencement  and  completion  of  clinical  trials  for  our  products,  including  the
APTO-253 phase I clinical trial, may be delayed for a number of reasons, including delays related, but not limited, to:

•

•

•

•

•

•

•

•
•

•

•

•

•

•

•

  failure by regulatory authorities to grant permission to proceed or placing the clinical trial on hold;

  patients failing to enroll or remain in our trials at the rate we expect;

  suspension or termination of clinical trials by regulators for many reasons, including concerns about patient safety or failure of our contract manufacturers to comply

with cGMP requirements;

  any changes to our manufacturing process that may be necessary or desired;

  delays or failure to obtain clinical supply from contract manufacturers of our products necessary to conduct clinical trials;

  product candidates demonstrating a lack of safety or efficacy during clinical trials;

  patients choosing an alternative treatment for the indications for which we are developing any of our product candidates or participating in competing clinical trials;

  patients failing to complete clinical trials due to dissatisfaction with the treatment, side effects or other reasons;
  reports of clinical testing on similar technologies and products raising safety and/or efficacy concerns;

  competing clinical trials and scheduling conflicts with participating clinicians;

  clinical investigators not performing our clinical trials on their anticipated schedule, dropping out of a trial, or employing methods not consistent with the clinical

trial protocol, regulatory requirements or other third parties not performing data collection and analysis in a timely or accurate manner;

  failure of our contract research organizations, or CROs, to satisfy their contractual duties or meet expected deadlines;

  inspections of clinical trial sites by regulatory authorities or Institutional Review Boards, or IRBs, or ethics committees finding regulatory violations that require us

to undertake corrective action, resulting in suspension or termination of one or more sites or the imposition of a clinical hold on the entire study;

  one or more IRBs or ethics committees rejecting, suspending or terminating the study at an investigational site, precluding enrollment of additional subjects, or

withdrawing its approval of the trial; or

  failure to reach agreement on acceptable terms with prospective clinical trial sites.

Our  product  development  costs  will  increase  if  we  experience  delays  in  testing  or  approval  or  if  we  need  to  perform  more  or  larger  clinical  trials  than  planned.
Additionally, changes in regulatory requirements and policies may occur, and we may need to amend study protocols to reflect these changes. Amendments may require us to
resubmit our study protocols to regulatory authorities or IRBs or ethics committees for re-examination, which may impact the cost, timing or successful completion of that trial.
Delays or increased product development costs may have a material adverse effect on our business, financial condition and prospects.

We rely on contract manufacturers over whom we have limited control. If we are subject to quality, cost or delivery issues with the preclinical and clinical grade materials
supplied by contract manufacturers, our business operations could suffer significant harm.

We rely on contract manufacturing organizations, or CMOs, to manufacture our product candidates for some preclinical studies and clinical trials. We rely on CMOs
for manufacturing, filling, packaging, storing and shipping of drug product in compliance with cGMP regulations applicable to our products. The FDA ensures the quality of
drug  products  by  carefully  monitoring  drug  manufacturers’  compliance  with  cGMP  regulations.  The  cGMP  regulations  for  drugs  contain  minimum  requirements  for  the
methods, facilities and controls used in manufacturing, processing and packing of a drug product.

We have contracted with multiple CMOs for the manufacture of APTO-253 to supply both the API as well as to perform formulation and optimization studies with the
intent of supplying drug product acceptable to the FDA for our phase I clinical trial. The formulation and manufacture of APTO-253 is a complex process with many variables
involved. We believe these pre-qualified CMOs have the capacity, the systems and the experience to supply APTO-253 for our phase I clinical trial and future clinical trials. We
have qualified the manufacturing facilities and the FDA has also performed site audits for our selected CMOs. Any manufacturing failures, delays or compliance issues could
cause further delays in the re-initiation of the phase I clinical trial. If we are able to re-initiate the phase I clinical trial any manufacturing failures, delays or compliance issues
could impact our ability to complete the phase I clinical trial.

There can be no assurances that CMOs will be able to meet our timetable and requirements. We have not contracted with alternate suppliers in the event our current
CMOs are unable to scale up production, or if our current CMOs otherwise experience any other significant problems. If we are unable to arrange for alternative third-party
manufacturing sources on commercially reasonable terms or in a timely manner, we may be further delayed in the development of our product candidates. Further, contract
manufacturers must operate in compliance with cGMP and failure to do so could result in, among other things, the disruption of product supplies. Our dependence upon third
parties for the manufacture of our products may adversely affect our profit margins and our ability to develop and deliver products on a timely and competitive basis.

Clinical trials are long, expensive and uncertain processes and the United States FDA or Health Canada may ultimately not approve any of our product candidates. We
may never develop any commercial drugs or other products that generate revenues.

In  the  past  five  years,  none  of  our  product  candidates  has  received  regulatory  approval  for  commercial  use  and  sale  in  North  America.  We  cannot  market  a
pharmaceutical product in any jurisdiction until it has completed thorough preclinical testing and clinical trials in addition to that jurisdiction’s extensive regulatory approval
process. Approval in one country does not assure approval in another country. In general, significant research and development and clinical studies are required to demonstrate
the safety and effectiveness of our product candidates before we can submit any regulatory applications.

Clinical trials are long, expensive and uncertain processes. Clinical trials may not be commenced or completed on schedule and the FDA or Health Canada or any other
regulatory body may not ultimately approve our product candidates for commercial sale. The clinical trials of any of our drug candidates could be unsuccessful, which would
prevent us from advancing, commercializing or partnering the drug.

Even  if  the  results  of  our  preclinical  studies  or  clinical  trials  are  initially  positive,  it  is  possible  that  we  will  obtain  different  results  in  the  later  stages  of  drug
development or that results seen in clinical trials will not continue with longer term treatment. Positive results in Phase I clinical trials may not be repeated in larger Phase II or
Phase III clinical trials.

Our preclinical studies and clinical trials may not generate positive results that will allow us to move towards the commercial use and sale of our product candidates.
Furthermore, negative preclinical or clinical trial results may cause our business, financial condition, or results of operations to be materially adversely affected. For example,
our product candidate APTO-253 has entered a Phase Ib testing in patients with relapsed or refractory hematologic malignancies for which there is a long development path
ahead  that  will  take  many  years  to  complete  and  is  prone  to  the  risks  of  failure  or  delays  inherent  in  drug  development  and  we  delayed  its  development  due  to  a  lack  of
resources.

Preparing, submitting and advancing applications for regulatory approval is complex, expensive and time intensive and entails significant uncertainty. A commitment

of substantial resources to conduct time-consuming research, preclinical studies and clinical trials is required if we are to complete development of our products.

Clinical  trials  of  our  products  require  that  we  identify  and  enroll  a  large  number  of  patients  with  the  illness  under  investigation.  We  may  not  be  able  to  enroll  a
sufficient  number  of  appropriate  patients  to  complete  our  clinical  trials  in  a  timely  manner,  particularly  in  smaller  indications  and  indications  where  there  is  significant
competition for patients. If we experience difficulty in enrolling a sufficient number of patients to conduct our clinical trials, we may need to delay or terminate ongoing clinical
trials and will not accomplish objectives material to our success. Delays in planned patient enrolment or lower than anticipated event rates in our current clinical trials or future
clinical trials also may result in increased costs, program delays, or both.

17

 
 
 
 
 
 
 
 
 
 
 
 
In  addition,  unacceptable  toxicities  or  adverse  side  effects  may  occur  at  any  time  in  the  course  of  preclinical  studies  or  human  clinical  trials  or,  if  any  product
candidates are successfully developed and approved for marketing, during commercial use of any approved products. The appearance of any unacceptable toxicities or adverse
side effects could interrupt, limit, delay or abort the development of any of our product candidates or, if previously approved, necessitate their withdrawal from the market.
Furthermore, disease resistance or other unforeseen factors may limit the effectiveness of our potential products.

Our failure to develop safe, commercially viable drugs would substantially impair our ability to generate revenues and sustain our operations and would materially

harm our business and adversely affect our share price.

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

We set goals for, and make public statements regarding, the expected timing of the accomplishment of objectives material to our success, such as the commencement
and completion of clinical trials and our ability to secure the financing necessary to continue the development of our product candidates. The actual timing of these events can
vary dramatically due to factors within and beyond our control, such as delays or failures in our clinical trials, issues related to the manufacturing of drug supply, uncertainties
inherent in the regulatory approval process, market conditions and interest by partners in our product candidates among other things. Our clinical trials may not be completed;
we  may  not  make  regulatory  submissions  or  receive  regulatory  approvals  as  planned;  or  we  may  not  secure  partnerships  for  any  of  our  product  candidates. Any  failure  to
achieve one or more of these milestones as planned would have a material adverse effect on our business, financial condition and results of operations.

If we have difficulty enrolling patients in clinical trials, the completion of the trials may be delayed or cancelled.

As our product candidates advance from preclinical testing to clinical testing, and then through progressively larger and more complex clinical trials, we will need to
enroll an increasing number of patients that meet our eligibility criteria. There is significant competition for recruiting cancer patients in clinical trials, and we may be unable to
enroll the patients we need to complete clinical trials on a timely basis or at all. Certain factors that affect enrollment of patients onto our clinical trials are impacted by external
forces that may be beyond our control. Such factors include, but are not limited to, the following:

•

•

•

•

•

•

•

  size and nature of the patient population;

  eligibility and exclusion criteria for the trial;

  design of the study protocol;

  competition with other companies for clinical sites or patients;

  the perceived risks and benefits of the product candidate under study;

  the patient referral practices of physicians; and

  the number, availability, location and accessibility of clinical trial sites.

If we are unable to successfully develop companion diagnostics for our therapeutic product candidates, or experience significant delays in doing so, we may not achieve
marketing approval or realize the full commercial potential of our therapeutic product candidates.

We  plan  to  develop  companion  diagnostics  for  our  therapeutic  product  candidates.  We  expect  that,  at  least  in  some  cases,  regulatory  authorities  may  require  the
development and regulatory approval of a companion diagnostic as a condition to approving our therapeutic product candidates. We have limited experience and capabilities in
developing or commercializing diagnostics and plan to rely in large part on third parties to perform these functions. We do not currently have any agreement in place with any
third party to develop or commercialize companion diagnostics for any of our therapeutic product candidates.

Companion  diagnostics  are  subject  to  regulation  by  the  FDA,  Health  Canada  and  comparable  foreign  regulatory  authorities  as  medical  devices  and  may  require
separate  regulatory  approval  or  clearance  prior  to  commercialization.  If  we,  or  any  third  parties  that  we  engage  to  assist  us,  are  unable  to  successfully  develop  companion
diagnostics for our therapeutic product candidates, or experience delays in doing so, our business may be substantially harmed.

We rely and will continue to rely on third parties to conduct and monitor many of our preclinical studies and our clinical trials, and their failure to perform as required
could cause substantial harm to our business.

We rely and will continue to rely on third parties to conduct a significant portion of our preclinical and clinical development activities. Preclinical activities include in
vivo  studies  providing  access  to  specific  disease  models,  pharmacology  and  toxicology  studies,  and  assay  development.  Clinical  development  activities  include  trial  design,
regulatory  submissions,  clinical  patient  recruitment,  clinical  trial  monitoring,  clinical  data  management  and  analysis,  safety  monitoring  and  project  management,  contract
manufacturing  and  quality  assurance.  If  there  is  any  dispute  or  disruption  in  our  relationship  with  third  parties,  or  if  they  are  unable  to  provide  quality  services  in  a  timely
manner and at a feasible cost, our active development programs will face delays. Further, if any of these third parties fails to perform as we expect or if their work fails to meet
regulatory requirements, our testing could be delayed, cancelled or rendered ineffective.

18

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We heavily rely on the capabilities and experience of our key executives and scientists and the loss of any of them could affect our ability to develop our products.

The loss of Dr. William G. Rice, our Chairman, President and Chief Executive Officer, or other key members of our staff, including Gregory Chow, our Senior Vice
President and Chief Financial Officer, could harm us. We have employment agreements with Dr. Rice and Mr. Chow although such employment agreements do not guarantee
their  retention.  We  also  depend  on  our  scientific  and  clinical  collaborators  and  advisors,  all  of  whom  have  outside  commitments  that  may  limit  their  availability  to  us.  In
addition, we believe that our future success will depend in large part upon our ability to attract and retain highly skilled scientific, managerial, medical, clinical and regulatory
personnel, particularly as we expand our activities and seek regulatory approvals for clinical trials. We routinely enter into consulting agreements with our scientific and clinical
collaborators and advisors, key opinion leaders and academic partners in the ordinary course of our business. We also enter into contractual agreements with physicians and
institutions  who  will  recruit  patients  into  our  clinical  trials  on  our  behalf  in  the  ordinary  course  of  our  business.  Notwithstanding  these  arrangements,  we  face  significant
competition for these types of personnel from other companies, research and academic institutions, government entities and other organizations. We cannot predict our success
in hiring or retaining the personnel we require for continued growth. The loss of the services of any of our executive officers or other key personnel could potentially harm our
business, operating results or financial condition.

Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, which could have a material
adverse effect on our business.

We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees could include failures to comply with FDA regulations, provide accurate
information  to  the  FDA,  comply  with  manufacturing  standards  we  have  established,  comply  with  federal  and  state  health-care  fraud  and  abuse  laws  and  regulations,  report
financial information or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry are subject
to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range
of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Employee misconduct could also involve
the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. If any such actions are
instituted  against  us,  and  we  are  not  successful  in  defending  ourselves  or  asserting  our  rights,  those  actions  could  have  a  substantial  impact  on  our  business  and  results  of
operations, including the imposition of substantial fines or other sanctions.

We may expand our business through the acquisition of companies or businesses or by entering into collaborations or by in-licensing product candidates, each of which
could disrupt our business and harm our financial condition.

We may in the future seek to expand our pipeline and capabilities by acquiring one or more companies or businesses, entering into collaborations or in-licensing one or
more product candidates. For example in November 2015 we licensed intellectual property from the Moffittt Cancer Center for exclusive global rights to potent, multi-targeting,
single-agent inhibitors for the treatment of hematologic and solid tumor cancers.

Acquisitions, collaborations and in-licenses involve numerous risks, including, but not limited to:

•

•

•

•

•

•

•

•

•

•

  substantial cash expenditures;

  technology development risks;

  potentially dilutive issuances of equity securities;

  incurrence of debt and contingent liabilities, some of which may be difficult or impossible to identify at the time of acquisition;

  difficulties in assimilating the operations of the acquired companies;

  potential disputes regarding contingent consideration;

  diverting our management’s attention away from other business concerns;

  entering markets in which we have limited or no direct experience;

  potential loss of our key employees or key employees of the acquired companies or businesses; and

  failure of the in-licensed agents or technologies to deliver the desired activities or functions.

We have experience in entering collaborations and in-licensing product candidates, however, we cannot provide assurance that any acquisition, collaboration or in-
license will result in short-term or long-term benefits to us. We may incorrectly judge the value or worth of an acquired company or business or in-licensed product candidate.
In addition, our future success would depend in part on our ability to manage the rapid growth associated with some of these acquisitions, collaborations and in-licenses. We
cannot  assure  you  that  we  would  be  able  to  successfully  combine  our  business  with  that  of  acquired  businesses,  manage  a  collaboration  or  integrate  in-licensed  product
candidates. Furthermore, the development or expansion of our business may require a substantial capital investment by us.

Negative results from clinical trials or studies of others and adverse safety events involving the targets of our products may have an adverse impact on our future
commercialization efforts.

From time to time, studies or clinical trials on various aspects of biopharmaceutical products are conducted by academic researchers, competitors or others. The results
of these studies or trials, when published, may have a significant effect on the market for the biopharmaceutical product that is the subject of the study. The publication of
negative results of studies or clinical trials or adverse safety events related to our product candidates, or the therapeutic areas in which our product candidates compete, could
adversely affect our share price and our ability to finance future development of our product candidates, and our business and financial results could be materially and adversely
affected.

As a result of intense competition and technological change in the biotechnical and pharmaceutical industries, the marketplace may not accept our products or product
candidates, and we may not be able to compete successfully against other companies in our industry and achieve profitability.

Many of our competitors have:

·

·

·

drug products that have already been approved or are in development, and operate large, well-funded research and development programs in the biotechnical and
pharmaceutical fields;

substantially  greater  financial,  technical  and  management  resources,  stronger  intellectual  property  positions  and  greater  manufacturing,  marketing  and  sales
capabilities, areas in which we have limited or no experience; and

significantly greater experience than we do in undertaking preclinical testing and clinical trials of new or improved pharmaceutical products and obtaining required
regulatory approvals.

Consequently,  our  competitors  may  obtain  FDA,  Health  Canada  and  other  regulatory  approvals  for  product  candidates  sooner  and  may  be  more  successful  in

manufacturing and marketing their products than we or our collaborators are.

Our  competitor’s  existing  and  future  products,  therapies  and  technological  approaches  will  compete  directly  with  the  products  we  seek  to  develop.  Current  and
prospective competing products may be more effective than our existing and future products insofar as they may provide greater therapeutic benefits for a specific problem or
may offer easier delivery or comparable performance at a lower cost.

Any product candidate that we develop and that obtains regulatory approval must then compete for market acceptance and market share. Our products may not gain
market  acceptance  among  physicians,  patients,  healthcare  payers,  insurers,  the  medical  community  and  other  stakeholders.  Further,  any  products  we  develop  may  become
obsolete before we recover any expenses we incurred in connection with the development of these products. As a result, we may never achieve profitability.

We may be unable to obtain patents to protect our technologies from other companies with competitive products, and patents of other companies could prevent us from
manufacturing, developing or marketing our products.

Patent protection

The  patent  positions  of  pharmaceutical  and  biotechnology  companies  are  uncertain  and  involve  complex  legal  and  factual  questions.  The  United  States  Patent  and
Trademark Office and many other patent offices in the world have not established a consistent policy regarding the breadth of claims  that  they  will  allow  in  biotechnology
patents.

Our pending patent applications may not result in issued patents and our issued patents may not be held valid and enforceable if challenged. Competitors may be able
to circumvent any such issued patents by adoption of a competitive, though non-infringing product or process. Interpretation and evaluation of pharmaceutical or biotechnology
patent  claims  present  complex  and  often  novel  legal  and  factual  questions.  Our  business  could  be  adversely  affected  by  increased  competition  in  the  event  that  any  patent
granted to it is held to be invalid or unenforceable or is inadequate in scope to protect our operations.

Allowable patentable subject matter and the scope of patent protection obtainable may differ between jurisdictions. If a patent office allows broad claims, the number
and cost of patent interference proceedings in the United States, or analogous proceedings in other jurisdictions and the risk of infringement litigation may increase. If it allows
narrow claims, the risk of infringement may decrease, but the value of our rights under our patents, licenses and patent applications may also decrease.

The scope of the claims in a patent application can be significantly modified during prosecution before the patent is issued. Consequently, we cannot know whether our
pending  applications  will  result  in  the  issuance  of  patents  or,  if  any  patents  are  issued,  whether  they  will  provide  us  with  significant  proprietary  protection  or  will  be
circumvented, invalidated or found to be unenforceable.

Publication of discoveries in scientific or patent literature often lags behind actual discoveries. Patent applications filed in the United States generally will be published
18 months after the filing date unless the applicant certifies that the invention will not be the subject of a foreign patent application. In many other jurisdictions, such as Canada,
patent applications are published 18 months from the priority date. We may not be aware of such literature. Accordingly, we cannot be certain that the named inventors of our
products and processes were the first to invent that product or process or that we were the first to pursue patent coverage for our inventions.

In addition, U.S. patent laws may change which could prevent or limit us from filing patent applications or patent claims in the United States to protect our products
and technologies or limit the exclusivity periods that are available to patent holders for U.S. patents. For example, the Leahy-Smith America Invents Act, (the “ Leahy-Smith
Act”) was signed into law in 2011 and includes a number of significant changes to U.S. patent law. These include changes to transition from a “first-to-invent” system to a “first-
to-file” system and to the way issued patents are challenged. These changes may favour larger and more established companies that have more resources to devote to patent
application filing and prosecution. It is not clear what, if any, impact the Leahy-Smith Act will ultimately have on the cost of prosecuting our patent applications in the United
States, our ability to obtain patents in the United States based on our discoveries and our ability to enforce or defend our U.S. issued patents.

Until such time, if ever, that further patents are issued to us, we will rely upon the law of trade secrets to the extent possible given the publication requirements under
international patent treaty laws and/or requirements under foreign patent laws to protect our technology and our products incorporating the technology. In this regard, we have
adopted certain confidentiality procedures. These include: limiting access to confidential information to certain key personnel; requiring all directors, officers, employees and
consultants  and  others  who  may  have  access  to  our  intellectual  property  to  enter  into  confidentiality  agreements  which  prohibit  the  use  of  or  disclosure  of  confidential
information to third parties; and implementing physical security measures designed to restrict access to such confidential information and products. Our ability to maintain the
confidentiality of our technology is crucial to our ultimate possible commercial success. The procedures adopted by us to protect the confidentiality of our technology may not
be effective, third parties may gain access to our trade secrets or disclose our confidential technology. Further, by seeking patent protection in various countries, it is inevitable
that a substantial portion of our technology will become available to our competitors, through publication of such patent applications.

Enforcement of intellectual property rights

Protection  of  the  rights  revealed  in  published  patent  applications  can  be  complex,  costly  and  uncertain.  Our  commercial  success  depends  in  part  on  our  ability  to
maintain and enforce our proprietary rights. If third parties engage in activities that infringe our proprietary rights, our management’s focus will be diverted and we may incur
significant costs in asserting our rights. We may not be successful in asserting our proprietary rights, which could result in our patents being held invalid or a court holding that
the third party is not infringing, either of which would harm our competitive position.

Others  may  design  around  our  patented  technology.  We  may  have  to  participate  in  interference  proceedings  declared  by  the  United  States  Patent  and  Trademark
Office, European opposition proceedings, or other analogous proceedings in other parts of the world to determine priority of invention and the validity of patent rights granted or
applied for, which could result in substantial cost and delay, even if the eventual outcome is favourable to us. Our pending patent applications, even if issued, may not be held
valid or enforceable.

Trade secrets

We also rely on trade secrets, know-how and confidentiality provisions in our agreements with our collaborators, employees and consultants to protect our intellectual
property.  However,  these  and  other  parties  may  not  comply  with  the  terms  of  their  agreements  with  us,  and  we  might  be  unable  to  adequately  enforce  our  rights  or  obtain
adequate compensation for the damages caused by unauthorized disclosure or use of our trade secrets or know how. Our trade secrets or those of our collaborators also may be
independently discovered by others.

Our products and product candidates may infringe the intellectual property rights of others, or others may infringe on our intellectual property rights which could increase
our costs.

Our success also depends on avoiding infringement of the proprietary technologies of others. In particular, there may be certain issued patents and patent applications
claiming subject matter which we or our collaborators may be required to license in order to research, develop or commercialize APTO-253, our lead product candidate. In
addition, third parties may assert infringement or other intellectual property claims against us. An adverse outcome in these proceedings could subject us to significant liabilities
to third-parties, require disputed rights to be licensed from third-parties or require us to cease or modify our use of the technology. If we are required to license third-party
technology, a license under such patents and patent applications may not be available on acceptable terms or at all. Further, we may incur substantial costs defending ourselves
in lawsuits against charges of patent infringement or other unlawful use of another’s proprietary technology. We may also need to bring claims against others who we believe
are infringing our rights in order to become or remain competitive and successful. Any such claims can be time consuming and expensive to pursue.

We may incur substantial cost in defending our intellectual property.

While we believe  that  our  products  and  technology  do  not  infringe  proprietary  rights  of  others,  third  parties  may  assert  infringement  claims  in  the  future  and  such
claims could be successful. Even if challenges are unsuccessful, we could incur substantial costs in defending ourselves against patent infringement claims brought by others or
in prosecuting suits against others. In addition, others may obtain patents that we would need to license, which may not be available to us on reasonable terms. Whether we are
able to obtain a necessary license would depend on the terms offered, the degree of risk of infringement and the need for the patent.

If product liability, clinical trial liability or environmental liability claims are brought against us or we are unable to obtain or maintain product liability, clinical trial or
environmental liability insurance, we may incur substantial liabilities that could reduce our financial resources.

The clinical testing and commercial use of pharmaceutical products involves significant exposure to product liability, clinical trial liability, environmental liability and
other risks that are inherent in the testing, manufacturing and marketing of our products. These liabilities, if realized, could have a material adverse effect on the Company’s
business, results of operations and financial condition.

We have obtained limited product liability insurance coverage for our clinical trials on humans; however, our insurance coverage may be insufficient to protect us
against  all  product  liability  damages.  Regardless  of  merit  or  eventual  outcome,  liability  claims  may  result  in  decreased  demand  for  a  future  product,  injury  to  reputation,
withdrawal  of  clinical  trial  volunteers,  loss  of  revenue,  costs  of  litigation,  distraction  of  management  and  substantial  monetary  awards  to  plaintiffs. Additionally,  if  we  are
required to pay a product liability claim, we may not have sufficient financial resources to complete development or commercialization of any of our product candidates and our
business and results of operations will be adversely affected. In general, insurance will not protect us against some of our own actions, such as negligence.

As the Company’s development activities progress towards the commercialization of product candidates, our liability coverage may not be adequate, and the Company
may  not  be  able  to  obtain  adequate  product  liability  insurance  coverage  at  a  reasonable  cost,  if  at  all.  Even  if  the  Company  obtains  product  liability  insurance,  its  financial
position may be materially adversely affected by a product liability claim. A product liability claim could also significantly harm the Company’s reputation and delay market
acceptance of its product candidates. Additionally, product recalls may be issued at the direction of the FDA, other government agencies or other companies having regulatory
control for pharmaceutical sales. If a product recall occurs in the future, such a recall could adversely affect our business, financial condition or reputation.

We  may  be  unable  to  obtain  partnerships  for  our  product  candidates,  which  could  curtail  future  development  and  negatively  affect  our  share  price.  In  addition,  our
partners might not satisfy their contractual responsibilities or devote sufficient resources to our partnership.

Our strategy for the research, development and commercialization of our products requires entering into various arrangements with corporate collaborators, licensors,
licensees and others, and our commercial success is dependent upon these outside parties performing their respective contractual responsibilities. The amount and timing of
resources  that  such  third  parties  will  devote  to  these  activities  may  not  be  within  our  control.  These  third  parties  may  not  perform  their  obligations  as  expected  and  our
collaborators may not devote adequate resources to our programs. In addition, we could become involved in disputes with our collaborators, which could result in a delay or
termination  of  the  related  development  programs  or  result  in  litigation.  We  intend  to  seek  additional  collaborative  arrangements  to  develop  and  commercialize  some  of  our
products. We may not be able to negotiate collaborative arrangements on favourable terms, or at all, in the future, and our current or future collaborative arrangements may not
be successful.

If we cannot negotiate collaboration, license or partnering agreements, we may never achieve profitability and we may not be able to continue to develop our product

candidates. Phase II and Phase III clinical trials for APTO-253 would require significant amounts of funding and such funding may not be available to us.

Exchange rate risk

We are exposed to fluctuations of the Canadian dollar against certain other currencies because we publish our financial statements and hold most of our investments in
Canadian  dollars,  while  we  incur  many  of  our  expenses  in  foreign  currencies,  primarily  the  United  States  dollar.  Fluctuations  in  the  value  of  currencies  such  as  the  recent
depreciation of the Canadian dollar against the United States dollar 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 Canadian dollar,
the United States dollar and other currencies.

Extensive Government Regulation

Government  regulation  is  a  significant  factor  in  the  development,  production  and  marketing  of  the  Company’s  products.  Research  and  development,  testing,
manufacture, marketing and sales of pharmaceutical products or related products are subject to extensive regulatory oversight, often in multiple jurisdictions, which may cause
significant additional costs and/or delays in bringing products to market, and in turn, may cause significant losses to investors. The regulations applicable to the Company's
product  candidates  may  change.  Even  if  granted,  regulatory  approvals  may  include  significant  limitations  on  the  uses  for  which  products  can  be  marketed  or  may  be
conditioned on the conduct of post-marketing surveillance studies. Failure to comply with applicable regulatory requirements can, among other things, result in warning letters,
the imposition of civil penalties or other monetary payments, delay in approving or refusal to approve a product candidate, suspension or withdrawal of regulatory approval,
product recall or seizure, operating restrictions, interruptions of clinical trials or manufacturing, injunctions or criminal prosecution. In addition, regulatory agencies many not
approve the labeling claims that are necessary or desirable for the successful commercialization of the Company’s product candidates.

Requirements for regulatory approval vary widely from country to country. Whether or not approved in Canada or the United States, regulatory authorities in other
countries must approve a product prior to the commencement of marketing the product in those countries. The time required to obtain any such approval may be longer or
shorter than in Canada or the United States. Approved drugs, as well as their manufacturers, are subject to continuing and ongoing review, and discovery of problems with these
products or the failure to adhere to manufacturing or quality control requirements may result in regulatory restrictions being imposed.

Risks Related to Our Common Shares

Our share price has been and is likely to continue to be volatile and an investment in our Common Shares could suffer a decline in value.

You should consider an investment in our Common Shares as risky and invest only if you can withstand a significant loss and wide fluctuations in the market value of
your investment. The market price of our Common Shares has been highly volatile and is likely to continue to be volatile. This leads to a heightened risk of securities litigation
pertaining to such volatility. Factors affecting our Common Share price include but are not limited to:

· our ability to raise additional capital;

· the progress of our clinical trials:

· our ability to obtain partners and collaborators to assist with the future development of our products;

· general market conditions;

· announcements of technological innovations or new product candidates by us, our collaborators or our competitors;

· published reports by securities analysts;

· developments in patent or other intellectual property rights;

· the cash and investments held by us and our ability to secure future financing;

· public concern as to the safety and efficacy of drugs that we and our competitors develop;

· shareholder interest in our Common Shares; and

· low liquidity in the daily trading volume of our Common Shares.

Future sales of our Common Shares by us or by our existing shareholders could cause our share price to fall.

The issuance of Common Shares by us could result in significant dilution in the equity interest of existing shareholders and adversely affect the market price of our
Common Shares. Sales by existing shareholders of a large number of our Common Shares in the public market and the issuance of shares issued in connection with strategic
alliances, or the perception that such additional sales could occur, could cause the market price of our Common Shares to decline and have an undesirable impact on our ability
to raise capital.

We are susceptible to stress in the global economy and therefore, our business may be affected by the current and future global financial condition.

If the increased level of volatility and market turmoil that have marked recent years continue, our operations, business, financial condition and the trading price of our
Common Shares could be materially adversely affected. Furthermore, general economic conditions may have a great impact on us, including our ability to raise capital, our
commercialization opportunities and our ability to establish and maintain arrangements with others for research, manufacturing, product development and sales.

23

 
 
 
 
 
 
 
 
 
 
 
 
 
An active trading market in our Common Shares may not be sustained.

Our  Common  Shares  are  listed  for  trading  on  the  NASDAQ  Capital  Market  (“NASDAQ”)  and  the  Toronto  Stock  Exchange  (“TSX”).  However,  an  active  trading

market in our Common Shares on the stock exchanges may not be sustained and we may not be able to maintain our listings.

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

We are a corporation existing under the laws of Canada. Some of our directors and officers, and many of the experts named in this Annual Report and the documents
incorporated by reference into this Annual Report, are residents of Canada, and all or a substantial portion of their assets, and a substantial portion of our assets, are located
outside  the  United  States.  Consequently,  although  we  have  appointed  an  agent  for  service  of  process  in  the  United  States,  it  may  be  difficult  for  holders  of  our  shares  who
reside  in  the  United  States  to  effect  service  within  the  United  States  upon  our  directors  and  officers  and  experts  who  are  not  residents  of  the  United  States.  It  may  also  be
difficult for holders of our shares who reside in the United States to realize in the United States upon judgments of courts of the United States predicated upon our civil liability
and the civil liability of our directors, officers and experts under the United States federal securities laws. Investors should not assume that Canadian courts (i) would enforce
judgments of United States courts obtained in actions against us or our directors, officers or experts predicated upon the civil liability provisions of the United States federal
securities laws or the securities or “blue sky” laws of any state within the United States or (ii) would enforce, in original actions, liabilities against us or our directors, officers or
experts predicated upon the United States federal securities laws or any such state securities or “blue sky” laws. In addition, we have been advised by our Canadian counsel that
in normal circumstances, only civil judgments and not other rights arising from United States securities legislation are enforceable in Canada and that the protections afforded
by Canadian securities laws may not be available to investors in the United States.

We are likely a “passive foreign investment company” which may have adverse U.S. federal income tax consequences for U.S. shareholders.

U.S. investors in our Common Shares should be aware that the Company believes it was classified as a passive foreign investment company (“PFIC”) during the tax
year  ended  December  31,  2015,  and  based  on  the  nature  of  our  business,  the  projected  composition  of  our  gross  income  and  the  projected  composition  and  estimated  fair
market value of our assets, the Company expects to be a PFIC for the current tax year ending December 31, 2016 and may be a PFIC in subsequent tax years. If the Company is
a PFIC for any year during a U.S. shareholder’s holding period, then such U.S. shareholder generally will be required to treat any gain realized upon a disposition of Common
Shares,  or  any  so-called  “excess  distribution”  received  on  its  Common  Shares,  as  ordinary  income,  and  to  pay  an  interest  charge  on  a  portion  of  such  gain  or  distributions,
unless the shareholder makes a timely and effective “qualified electing fund” election (“QEF election”) or a “mark-to-market” election with respect to the Common Shares. A
U.S. shareholder who makes a QEF election generally must report on a current basis its share of the Company’s net capital gain and ordinary earnings for any year in which the
Company is a PFIC, whether or not the Company distributes any amounts to its shareholders. However, U.S. shareholders should be aware that we do not intend to satisfy
record keeping requirements that apply to a qualified electing fund, and we do not intend to supply U.S. shareholders with information that such U.S. shareholders require to
report under the QEF election rules, in the event that we are a PFIC and a U.S. shareholder wishes to make a QEF election. Thus, U.S. shareholders should assume that they will
not  be  able  to  make  a  QEF  election  with  respect  to  their  Common  Shares. A  U.S.  shareholder  who  makes  the  mark-to-market  election  generally  must  include  as  ordinary
income each year the excess of the fair market value of the Common Shares over the taxpayer’s basis therein. This paragraph is qualified in its entirety by the discussion below
under the heading “Certain United States Federal Income Tax Considerations.” Each U.S. shareholder should consult its own tax advisor regarding the U.S. federal, U.S. local,
and foreign tax consequences of the PFIC rules and the acquisition, ownership, and disposition of our Common Shares.

We are an “emerging growth company,” and we cannot be certain if the reduced reporting requirements applicable to emerging growth companies will make our

common shares less attractive to investors.

We are an “emerging growth company,” as defined in the U.S. Jumpstart Our Business Startups Act of 2012, or the JOBS Act. For as long as we continue to be an
emerging  growth  company,  we  may  take  advantage  of  exemptions  from  various  reporting  requirements  that  are  applicable  to  other  public  companies  that  are  not  emerging
growth companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations
regarding  executive  compensation  in  our  periodic  reports  and  exemptions  from  the  requirements  of  holding  a  nonbinding  advisory  vote  on  executive  compensation  and
shareholder approval of any golden parachute payments not previously approved.

We will cease to be an emerging growth company upon the earliest of:

•

the last day of the fiscal year during which we have total annual gross revenues of $1,000,000,000 (as such amount is indexed for inflation every five years by the SEC or
more;

24

 
 
 
 
 
 
 
 
 
 
 
 
•

•

•

the last day of our fiscal year following the fifth anniversary of the completion of our first sale of common equity securities pursuant to an effective registration statement
under the Securities Act;

the date on which we have, during the previous three-year period, issued more than $1,000,000,000 in non- convertible debt; or

the date on which we are deemed to be a “large accelerated filer”, as defined in Rule 12b–2 of the Exchange Act, which would occur if the market value of our ordinary
shares and ADSs that are held by non-affiliates exceeds $700,000,000 as of the last day of our most recently-completed second fiscal quarter.

We cannot predict if investors will find our common shares less attractive because we may rely on these exemptions. If some investors find our Common Shares less

attractive as a result, there may be a less active trading market for our Common Shares and our share price may be more volatile.

Any failure to maintain an effective system of internal controls may result in material misstatements of our consolidated financial statements or cause us to fail to
meet our reporting obligations or fail to prevent fraud; and in that case, our shareholders could lose confidence in our financial reporting, which would harm our business
and could negatively impact the price of our common shares.

Section 404(a) of the Sarbanes-Oxley Act of 2002, as amended, or SOX, requires that our management assess and report annually on the effectiveness of our internal
controls  over  financial  reporting  and  identify  any  material  weaknesses  in  our  internal  controls  over  financial  reporting. Although  Section  404(b)  of  the  SOX  requires  our
independent registered public accounting firm to issue an annual report that addresses the effectiveness of our internal controls over financial reporting, we have opted to rely on
the exemptions provided to us by virtue of being a foreign private issuer and an emerging growth company, and consequently will not be required to comply with SEC rules that
implement Section 404(b) of SOX until we lose our emerging growth company status.

Effective internal controls are necessary for us to provide reliable financial reports and prevent fraud. If we fail to maintain an effective system of internal controls, we
might not be able to report our financial results accurately or prevent fraud; and in that case, our shareholders could lose confidence in our financial reporting, which would
harm  our  business  and  could  negatively  impact  the  price  of  our  common  shares.  While  we  believe  that  we  have  sufficient  personnel  and  review  procedures  to  allow  us  to
maintain an effective system of internal controls, we cannot assure you that we will not experience potential material weaknesses in our internal control. Even if we conclude
that  our  internal  control  over  financial  reporting  provides  reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  consolidated  financial
statements for external purposes in accordance with IFRS, as issued by the International Accounting Standards Board, because of its inherent limitations, internal control over
financial  reporting  may  not  prevent  or  detect  fraud  or  misstatements.  Failure  to  implement  required  new  or  improved  controls,  or  difficulties  encountered  in  their
implementation, could harm our results of operations or cause us to fail to meet our future reporting obligations.

If we fail to timely achieve and maintain the adequacy of our internal control over financial reporting, we may not be able to produce reliable financial reports or help
prevent fraud. Our failure to achieve and maintain effective internal control over financial reporting could prevent us from complying with our reporting obligations on a timely
basis, which could result in the loss of investor confidence in the reliability of our consolidated financial statements, harm our business and negatively impact the trading price
of our common shares.

As a foreign private issuer, we are not subject to certain United States securities law disclosure requirements that apply to a domestic United States issuer, which

may limit the information which would be publicly available to our shareholders.

As a foreign private issuer, we are exempt from certain rules under the Exchange Act that impose disclosure requirements as well as procedural requirements for proxy
solicitations  under  Section  14  of  the  Exchange Act.  In  addition,  our  officers,  directors  and  principal  shareholders  are  exempt  from  the  reporting  and  “short-swing”  profit
recovery provisions of Section 16 of the Exchange Act. Moreover, we are not required to file periodic reports and financial statements with the SEC as frequently or as promptly
as a company that files as a domestic issuer whose securities are registered under the Exchange Act, nor are we generally required to comply with the SEC’s Regulation FD,
which restricts the selective disclosure of material non-public information. For as long as we are a “foreign private issuer” we intend to file our annual financial statements on
Form 20-F and furnish our quarterly updates on Form 6-K to the SEC for so long as we are subject to the reporting requirements of Section 13(g) or 15(d) of the Exchange Act.
However, the information we file or furnish is not the same as the information that is required in annual and quarterly reports on Form 10-K or Form 10-Q for U.S. domestic
issuers. Accordingly, there may be less information publicly available concerning us than there is for a company that files as a domestic issuer.

DISCLOSURE CONTROLS AND INTERNAL CONTROL OVER FINANCIAL REPORTING
The Company has implemented a system of internal controls that it believes adequately protects the assets of the Company and is appropriate for the nature of its business and
the size of its operations. Our internal control system was designed to provide reasonable assurance that all transactions are accurately recorded, that transactions are recorded as
necessary to permit preparation of financial statements in accordance with IFRS, and that our assets are safeguarded. These internal controls include disclosure controls and
procedures designed to ensure that information required to be disclosed by the Company is accumulated and communicated as appropriate to allow timely decisions regarding
required disclosure.

Internal  control  over  financial  reporting  means  a  process  designed  by  or  under  the  supervision  of  the  Chief  Executive  Officer  and  the  Chief  Financial  Officer,  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. The internal controls are not expected to prevent and detect all misstatements due to error or fraud.

There were no changes in our internal control over financial reporting that occurred during the year ended December 31, 2016 that have materially affected, or are reasonably
likely to materially affect, our internal control over financial reporting

As of December 31, 2016, the Company’s management has assessed the effectiveness of our internal control over financial reporting and disclosure controls and procedures
using  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission’s  2013  framework.  Based  on  their  evaluation,  the  Chief  Executive  Officer  and  the  Chief
Financial Officer have concluded that these controls and procedures are effective.

UPDATED SHARE INFORMATION

As at March 28, 2017, we had 18,849,224 common shares issued and outstanding. In addition there were 1,970,587 common shares issuable upon the exercise of outstanding
stock options.
