its Subsidiaries on a consolidated basis. Other than the Company changing its accounting principles from IFRS to GAAP commencing

any Subsidiary received written notice of a claim that it is in default under or that it is in violation of, any indenture, loan
or credit agreement or any other agreement (including any Material Contract) or instrument to which it is a party or by which it
or any of its properties is bound (whether or not such default or violation has been waived), (ii) neither the Company nor any

which might give rise to any of the foregoing. The Company and its Subsidiaries have taken reasonable security measures to protect
the secrecy, confidentiality and value of all of their intellectual properties, except where failure to do so would not, individually
or in the aggregate, reasonably be expected to have a Material Adverse Effect.

THE FACILITIES OF THE TSX SINCE THEY ARE NOT FREELY TRANSFERABLE, AND CONSEQUENTLY ANY CERTIFICATE REPRESENTING SUCH SECURITIES
IS NOT ‘GOOD DELIVERY’ IN SETTLEMENT OF TRANSACTIONS ON THE TSX.

the Purchased Shares are entered into a direct registration or other electronic book entry system, or if the Investor did not directly
receive a certificate representing the Purchased Shares, the Company has hereby provided the Investor with written notice pursuant

Article
VI

INDEMNIFICATION



6.1 Indemnification
of Investors The Company will indemnify and hold each Investor and its directors, officers, shareholders, members, partners,
employees and agents (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding
a lack of such title or any other title), each Person who controls such Investor (within the meaning of Section 15 of the Securities
Act and Section 20 of the Exchange Act), and the directors, officers, shareholders, agents, members, partners or employees (and
any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any
other title) of such controlling person (each, an “Investor Party”) harmless from any and all losses, liabilities,
obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs
and reasonable attorneys’ fees and reasonable costs of investigation that any such Investor Party may suffer or incur, as
a result of or relating to third party claims against such Investor relating to any breach of any of the representations, warranties,
covenants or agreements made by the Company in this Agreement or in the other Transaction Documents, provided that that such a
claim for indemnification relating to any breach of any of the representations or warranties made by the Company in this Agreement
is made within six months from the Closing. The Company will not be liable to any Investor Party under this Agreement to the extent,
but only to the extent that a loss, claim, damage or liability is attributable to any Investor Party’s breach of any of the
representations, warranties, covenants or agreements made by such Investor Party in this Agreement or in the other Transaction
Documents.



20









6.2 Conduct
of Indemnification Proceedings Promptly after receipt by any Person (the “Indemnified Person”) of notice of any
demand, claim or circumstances which would or might give rise to a claim or the commencement of any action, proceeding or investigation
in respect of which indemnity may be sought pursuant to Section 6.1, such Indemnified Person shall promptly notify the Company
in writing, and the Company shall assume the defense thereof, and shall assume the payment of all fees and expenses; provided,
however , that the failure of any Indemnified Person so to notify the Company shall not relieve the Company of its obligations
hereunder except to the extent that the Company is actually prejudiced by such failure to notify. In any such proceeding, any Indemnified
Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such
Indemnified Person unless: (i) the Company and the Indemnified Person shall have mutually agreed to the retention of such counsel;
(ii) the Company shall have failed promptly to assume the defense of such proceeding and to employ counsel reasonably satisfactory
to such Indemnified Person in such proceeding; or (iii) in the reasonable judgment of counsel to such Indemnified Person, representation
of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them in such
proceeding; provided, that, in the case of the foregoing clauses (i) through (iii), the Company shall not pay for more than one
counsel for all Indemnified Persons. The Company shall not be liable for any settlement of any proceeding effected without its
written consent, which consent shall not be unreasonably withheld, delayed or conditioned. Without the prior written consent of
the Indemnified Person, which consent shall not be unreasonably withheld, delayed or conditioned, the Company shall not effect
any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party
and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release
of such Indemnified Person from all liability arising out of such proceeding.

7.13 Independent Nature
of Investors’ Obligations and Rights The obligations of each Investor under any Transaction Document are several and
not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance of the

to this Agreement has been made by such Investor independently of any other Investor and independently of any information, materials,
statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition
(financial or otherwise) or prospects of the Company which may have been made or given by any other Investor or by any agent or
employee of any other Investor, and no Investor or any of its agents or employees shall have any liability to any other Investor
(or any other person) relating to or arising from any such information, materials, statements or opinions. Nothing contained herein
or in any Transaction Document, and no action taken by any Investor pursuant thereto, shall be deemed to constitute the Investors
as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in
any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Document.
Each Investor acknowledges that no other Investor has acted as agent for such Investor in connection with making its investment
hereunder and that no other Investor will be acting as agent of such Investor in connection with monitoring its investment hereunder.
Each Investor shall be entitled to independently protect and enforce its rights, including without limitation the rights arising
out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Investor to be joined
as an additional party in any Proceeding for such purpose.
