| | A. | Disclosure Controls and Procedures
| | -- | ----------------------------------



Disclosure controls and procedures are defined in Rule 13a-15(e)
and Rule 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), by the Securities and
Exchange Commission (the “Commission”) as those controls and other procedures that are designed to ensure that information
required to be disclosed by the Registrant in reports filed or submitted by it under the Exchange Act is recorded, processed, summarized
and reported within the time periods specified in the Commission’s rules and forms. Disclosure controls and procedures include,
without limitation, controls and procedures designed to ensure that information required to be disclosed in the Registrant’s
reports and filings is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer,
as appropriate, to allow timely decisions regarding required disclosure.



The Registrant’s Chief Executive Officer and Chief Financial
Officer have evaluated the effectiveness of the Registrant’s disclosure controls and procedures and have concluded that such
disclosure controls and procedures were effective as at December 31, 2016. See “Disclosure Controls and Procedures (DCP)
and Internal Controls over Financial Reporting (ICFR)” in Management’s Discussion and Analysis of Financial Condition
and Results of Operations for the fiscal year ended December 31, 2016, filed as Exhibit No. 1.3 to this Annual Report on Form 40-F.



| | B. | Management’s Annual Report on Internal Control over Financial Reporting
| | -- | -----------------------------------------------------------------------



The Registrant’s management, including its Chief Executive
Officer and Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting
(as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) and has designed such internal control over financial reporting
to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for
external purposes in accordance with International Financial Reporting Standards, as prepared by the International Accounting Standards
Board. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.
Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because
of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.



The Registrant’s management has evaluated the design and
operation of its internal control over financial reporting as of December 31, 2016 and has concluded that such internal control
over financial reporting was effective as of December 31, 2016. This assessment was based on the framework in Internal Control—Integrated
Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. See “Disclosure Controls
and Procedures (DCP) and Internal Controls over Financial Reporting (ICFR)” in Management’s Discussion and Analysis
of Financial Condition and Results of Operations for the fiscal year ended December 31, 2016, filed as Exhibit No. 1.3 to this
Annual Report on Form 40-F.

attestation requirements of the U.S. Sarbanes-Oxley Act of 2002 for so long as the Registrant remains an “emerging growth
company” under the Jumpstart Our Business & Startups Act.



There were no changes in the Registrant’s internal control
over financial reporting that occurred during the period covered by this Annual Report on Form 40-F that have materially affected,
or are reasonably likely to materially affect, the Registrant’s internal control over financial reporting.



| | D. | Notice of Pension Fund Blackout Period

The Board has determined that Todd Patrick is an audit committee
financial expert within the meaning of General Instruction B(8)(b) of Form 40-F under the Exchange Act.Todd Patrick is
“independent” within the meaning of Rule 10A-3 under the Exchange Act and the listing standards of the NYSE MKT. The
Commission has indicated that the designation or identification of a person as an audit committee financial expert does not make
such person an “expert” for any purpose, impose any duties, obligations or liability on such person that are greater
than those imposed on members of the Audit Committee and the Board who do not carry this designation or identification, or affect
the duties, obligations or liability of any other member of the Audit Committee or the Board.
