THIS CERTIFIES that, for value received:

 

«Registration»

 

(hereinafter referred to as the “Holder”)

 

is the registered holder of that number of warrants
(the “Warrants”) of ProMis Neurosciences Inc. (the “Issuer”) set forth above.

 

Underlying Securities and Exercise Terms

 

Each Warrant entitles the Holder to purchase one
common share (each a “Common Share”) of the Issuer, as constituted on April 30, 2018, at a price of CAD$0.48 per Common
Share until 5:00 pm (EST) on April 30, 2023 (the “Expiry Date”). The Expiry Date may be accelerated by the Issuer at
any time following the four-month anniversary of the issue date of the Warrants and prior to the Expiry Date if the volume-weighted average
trading price of the Common Shares on the TSX is greater than CAD$1.00 for any twenty (20) consecutive trading days, at which time the
Issuer may accelerate the Expiry Date by issuing a press release announcing the reduced term of the Warrants, whereupon the Warrants will
expire on the thirtieth (30th) calendar day after the date of such press release.

 

The Warrants and Common Shares are collectively
referred to herein as the “Securities”.

 

Warrant Exercise Procedure

 

The Warrants may be exercised at any time prior
to the expiry of the Warrants by surrendering to the Issuer at its head office, at Suite 200, 1920 Yonge Street, Toronto, Ontario,
M4S 3E2:

 

		(a)	this Warrant Certificate;

 

		(b)	the Subscription Form attached as Schedule “A” hereto, duly completed and executed; and

 

		(c)	a cheque, bank draft or money order made payable to the Issuer in the aggregate amount of the exercise
price,

 

or such other office or agency of the Issuer as
it may designate by notice in writing delivered to the Holder at the Holder’s address stated above. Upon the due exercise of the
Warrants, the Issuer shall issue or cause to be issued the requisite number of Common Shares to be issued to the Holder pursuant to said
exercise, registered in the name of the Holder or such other person as may be specified in the Subscription Form, and each such person
shall be deemed the holder of such Common Shares with effect from the date of such exercise. If Common Shares are to be issued to a person
other than the Holder, the Holder’s signature on the Subscription Form must be guaranteed by a Canadian chartered bank, a Canadian
trust company or a member firm of the TSX. The Issuer will cause the certificates representing such Common Shares to be mailed to the
Holder at the Holder’s address stated above or such other address(es) as may be specified in the Subscription Form, within five
business days of the exercise of the Warrants.

 

    

     

    

 

Upon the due exercise of a Warrant, the Warrant
shall be deemed tendered for purposes thereof by the Holder without further notice or action by the Holder, and all rights under such
Warrant, other than the right to receive certificates representing the Common Shares to which the Holder is entitled on such exercise,
shall wholly cease and terminate and such Warrants shall be void and of no further effect or value.

 

Partial Exercise, Exchange and Replacement
of Certificates

 

The Warrants represented by this Warrant Certificate
may be exercised in whole or in part from time to time. If the Warrants are exercised in part, the Issuer shall deliver, with the Common
Shares issued pursuant to such exercise, a new Warrant Certificate representing the balance of the Warrants remaining unexercised.

 

This Warrant Certificate may be exchanged, upon
its surrender to the Issuer and payment of such administration fee, not exceeding $10.00, as the Issuer may require, for new Warrant Certificates
of like tenor in denominations which in the aggregate represent the number of Warrants represented hereby.

 

If this Warrant Certificate is lost, stolen, mutilated
or destroyed, the Issuer may on such reasonable terms as it may in its discretion impose, including but not limited to the payment of
any administration fee, not exceeding $10.00, and the provision of any indemnity by the Holder, issue and countersign a new Warrant Certificate
of like tenor, denomination and date as the Warrant Certificate so lost, stolen, mutilated or destroyed.

 

All Warrants shall rank pari passu, notwithstanding
the actual date of issue thereof.

 

Covenants

 

The Issuer covenants and agrees that so long as
any Warrants evidenced hereby remain outstanding, it shall reserve and there shall remain unissued out of its authorized capital a sufficient
number of Common Shares to satisfy the right of purchase herein provided for and such Common Shares shall be issued as fully paid and
non-assessable Common Shares and the holders thereof shall not be liable to the Issuer or to its creditors in respect thereof.

 

The
Issuer shall use all reasonable commercial efforts to preserve and maintain its corporate existence and to ensure that the Common Shares
outstanding or issuable from time to time upon the exercise of the Warrants are listed and posted for trading on the TSX (or such
other exchange on which the Common Shares may be listed), provided that this clause shall not be construed as limiting or restricting
the Issuer from completing a consolidation, amalgamation, arrangement, takeover bid or merger that would result in the Common Shares ceasing
to be listed and posted for trading on the TSX (or such other exchange on which the Common Shares may be listed), so long as the holders
of Common Shares receive securities of an entity which is listed on a stock exchange in Canada, or cash, or the holders of the Common
Shares have approved the transaction in accordance with the requirements of applicable corporate and securities laws and the policies
of the TSX (or such other exchange on which the Common Shares may be listed). In addition, the Issuer shall make all requisite filings
under applicable securities legislation necessary to remain a reporting issuer not in default.

 

If the issuance of the Common Shares upon the
exercise of the Warrants requires any filing or registration with or approval of any securities regulatory authority or other governmental
authority or compliance with any other requirement under any law before such Common Shares may be validly issued (other than the filing
of a prospectus or similar disclosure document), the Issuer agrees to take such actions as may be necessary to secure such filing, registration,
approval or compliance, as the case may be.

 

Transfer of Warrants

 

The Warrants are non-transferable.

 

    

     

    

 

Holding of Warrants

 

The Issuer may treat the Holder as the absolute
owner of the Warrants represented hereby for all purposes, and the Issuer shall not be affected by any notice or knowledge to the contrary
except where the Issuer is required to take notice by statute or by order of a court of competent jurisdiction.

 

Nothing in this Warrant Certificate or in the
holding of a Warrant evidenced hereby shall be construed as conferring upon the Holder any right or interest whatsoever as a shareholder
of the Issuer or entitle the Holder to any right or interest in respect of any Common Shares except as herein expressly provided.

 

Resale Restrictions and Legending Of Certificates

 

The Warrants have been, and the Common Shares
will be, issued pursuant to an exemption (an “Exemption”) from the registration and prospectus requirements of applicable
securities law. To the extent that the Issuer relies on such Exemption, the Common Shares may be subject to restrictions on resale and
transferability contained in applicable securities laws.

 

If any of the Securities are subject to a hold
period, or any other restrictions on resale and transferability, the Issuer may place a legend on the certificates representing the Securities
as may be required under applicable securities laws, or as it may otherwise deem necessary or advisable.

 

Any certificate representing Common Shares issued
upon the exercise of this Warrant prior to the date which is four months and one day after the Issue Date will bear the following legends:

 

UNLESS PERMITTED UNDER SECURITIES LEGISLATION,
THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY BEFORE AUGUST 31, 2018.

 

and

 

THE SECURITIES REPRESENTED BY THIS CERTIFICATE
ARE LISTED ON THE TORONTO STOCK EXCHANGE (“TSX”); HOWEVER, THE SECURITIES CANNOT BE TRADED THROUGH 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.

 

provided that at any time subsequent to the date
which is four months and one day after the date hereof any certificate representing such Common Shares may be exchanged for a certificate
bearing no such legends.

 

Capital Adjustments

 

Subject
to approval of the TSX (or such other exchange on which the Common Shares may be listed), if at any time after the date hereof
and prior to the expiry of the Warrants, and provided that any Warrants remain unexercised, there shall be:

 

		(a)	a reclassification of the Common Shares, a change in the Common Shares into other shares or securities,
a subdivision or consolidation of the Common Shares into a greater or lesser number of Common Shares, or any other capital reorganization,
or

 

		(b)	a consolidation, amalgamation or merger of the Issuer with or into any other corporation other than a
consolidation, amalgamation or merger which does not result in any reclassification of the outstanding Common Shares or a change of the
Common Shares into other shares or securities,

 

(any of such events being called a “Capital
Reorganization”) any Holders who shall thereafter acquire Common Shares pursuant to the Warrant shall be entitled to receive, at
no additional cost, and shall accept in lieu of the number of Common Shares to which such Holder was theretofore entitled to acquire upon
such exercise, the aggregate number of shares, other securities or other property which such Holder should have been entitled to receive
as a result of such Capital Reorganization if, on the effective date or record date thereof as the case may be, the Holder had been the
registered holder of the number of Common Shares to which such Holder was theretofore entitled to acquire upon exercise of the Warrants.
If determined appropriate by the Issuer acting reasonably, appropriate adjustments shall be made in the application of the provisions
set forth herein with respect to the rights and interests of the Holder relative to a Capital Reorganization, to the end that the provisions
set forth herein shall correspond as nearly as may be reasonably possible to the effect of the Capital Reorganization in relation to any
shares, other securities or other property thereafter deliverable upon the exercise of any Warrants.

 

    

     

    

 

In case at any time:

 

		(a)	the Issuer shall pay any dividend payable in stock upon its Common Shares or make any distribution to
the holders of its Common Shares;

 

		(b)	the Issuer shall offer for subscription pro rata to the holders of its Common Shares any additional shares
or stock of any class or other rights;

 

		(c)	there shall be any subdivision, consolidation, capital reorganization, or reclassification of the capital
stock of the Issuer, or merger, amalgamation or arrangement of the Issuer with, or sale of all or substantially all of its assets to,
another corporation; or

 

		(d)	there shall be a voluntary or involuntary dissolution, liquidation or winding-up of the Issuer,

 

the Issuer shall give to the Holder at least twenty
days’ prior written notice of the date on which the books of the Issuer shall close or a record shall be established for such dividend,
distribution or subscription rights, or for determining rights to vote with respect to such subdivision, consolidation, capital reorganization,
reclassification, merger, amalgamation, arrangement, sale, dissolution, liquidation or winding-up, and in the case of any such subdivision,
consolidation, capital reorganization, reclassification, merger, amalgamation, arrangement, sale, dissolution, liquidation or winding-up,
at least twenty days’ prior written notice of the date when the same shall take place. Such notice in accordance with the foregoing
clause shall also specify, in the case of any such dividend, distribution or subscription rights, the date on which the holders of Common
Shares shall be entitled thereto, and such notice in accordance with the foregoing shall also specify, in the case of any such subdivision,
consolidation, capital reorganization, reclassification, merger, amalgamation, arrangement, sale, dissolution, liquidation or winding-up,
the date on which the holders of Common Shares shall be entitled to exchange their Common Shares for securities or other property deliverable
upon such subdivision, consolidation, capital reorganization, reclassification, merger, amalgamation, arrangement, sale, dissolution,
liquidation or winding-up as the case may be. Each such written notice shall be given by first class mail, postage prepaid, addressed
to the Holder at its address as shown on the books of the Issuer.

 

In case the Issuer, after the date hereof, shall
take any action affecting any securities of the Issuer, other than as previously set out herein, which in the opinion of the directors
would materially affect the rights and interests of the Holder hereunder, the number of Common Shares or other securities which shall
be issuable on the exercise of the Warrants shall be adjusted in such manner, if any, and at such time as the directors, in their sole
discretion, may determine to be equitable in the circumstances, provided that no such adjustment will be made unless all necessary regulatory
approvals, if any, have been obtained. In the event of any question arising with respect to any adjustment provided for herein, such question
shall be conclusively determined by a firm of chartered accountants appointed by the Issuer at its sole discretion (who may be the Issuer’s
auditors) and any such determination shall be binding upon the Issuer and the Holder.

 

No
adjustment shall be made in respect of any event described herein if the Holder is entitled to participate in such event on the same terms,
without amendment, as if the Holder had exercised the Warrants prior to or on the effective date or record date of such event, subject
to the written consent of the TSX (or such other exchange on which the Common Shares may be listed). The adjustments provided for
herein are cumulative and such adjustments shall be made successively whenever an event referred to herein shall occur, subject to the
limitations provided for herein. No adjustment shall be made in the number or kind of Shares or other securities which may be acquired
on the exercise of a Warrant unless it would result in a change of at least one-tenth of a Share or other security. Any adjustment which
may by reason of this paragraph not be required to be made shall be carried forward and then taken into consideration in any subsequent
adjustment.

 

Notwithstanding any adjustments provided for herein
or otherwise, the Issuer shall not be required, upon the exercise of any Warrants, to issue fractional Common Shares or other securities
in satisfaction of its obligations hereunder and, except as provided for herein, any fractions shall be eliminated. To the extent that
the Holder would otherwise be entitled to acquire a fraction of a Common Share or other security, such right may be exercised in respect
of such fraction only in combination with other rights which in the aggregate entitle the Holder to acquire a whole number of Common Shares
or other securities. The Holder shall be entitled, upon the elimination of any fraction of a Common Share or other security, to be paid
in cash for the fair market value for the securities so eliminated, always provided that the Issuer shall not be required to make any
payment if for less than $10.00.

 

    

     

    

 

Representation and Warranty

 

The Issuer hereby represents and warrants
with and to the Holder that the Issuer is duly authorized and has the corporate and lawful power and authority to create and issue
this Warrant and the Common Shares issuable upon the exercise hereof and perform its obligations hereunder and that this Warrant
represents a valid, legal and binding obligation of the Issuer enforceable in accordance with its terms.

notice in writing delivered in one of the foregoing manners.

 

Except as herein provided, any and all of the
rights conferred upon the Holder herein may be enforced by the Holder through appropriate legal proceedings. No recourse under or upon
any covenant, obligation or agreement herein contained shall be had against any shareholder, officer or director of the Issuer, either
directly or through the Issuer, it being expressly agreed and declared that the obligations under the Warrants are solely corporate obligations
of the Issuer and no personal liability whatsoever shall attach to or be incurred by the shareholders, officers or directors of the Issuer
in respect thereof. This Warrant Certificate shall be binding upon the Issuer and its successors.

 

This Warrant shall be governed in accordance with
the laws of British Columbia and the laws of Canada applicable therein. The parties hereby attorn to the jurisdiction of the courts of
British Columbia in the event of any dispute hereunder. Time shall be of the essence hereof.

Share until 5:00 pm (EST) on April 30, 2023 (the “Expiry Date”). The Expiry Date may be accelerated by the Issuer at
any time following the four-month anniversary of the issue date of the Warrants and prior to the Expiry Date if the volume-weighted average
trading price of the Common Shares on the TSX is greater than CAD$1.00 for any twenty (20) consecutive trading days, at which time the
Issuer may accelerate the Expiry Date by issuing a press release announcing the reduced term of the Warrants, whereupon the Warrants will

The Warrants and Common Shares are collectively

Warrant Exercise Procedure

 

The Warrants may be exercised at any time prior

M4S 3E2:

 

		(a)	this Warrant Certificate;

Warrants, the Issuer shall issue or cause to be issued the requisite number of Common Shares to be issued to the Holder pursuant to said
exercise, registered in the name of the Holder or such other person as may be specified in the Subscription Form, and each such person
shall be deemed the holder of such Common Shares with effect from the date of such exercise. If Common Shares are to be issued to a person
other than the Holder, the Holder’s signature on the Subscription Form must be guaranteed by a Canadian chartered bank, a Canadian
trust company or a member firm of the TSX. The Issuer will cause the certificates representing such Common Shares to be mailed to the
Holder at the Holder’s address stated above or such other address(es) as may be specified in the Subscription Form, within five

shall be deemed tendered for purposes thereof by the Holder without further notice or action by the Holder, and all rights under such
Warrant, other than the right to receive certificates representing the Common Shares to which the Holder is entitled on such exercise,
shall wholly cease and terminate and such Warrants shall be void and of no further effect or value.

 

Partial Exercise, Exchange and Replacement
of Certificates

 

The Warrants represented by this Warrant Certificate
may be exercised in whole or in part from time to time. If the Warrants are exercised in part, the Issuer shall deliver, with the Common
Shares issued pursuant to such exercise, a new Warrant Certificate representing the balance of the Warrants remaining unexercised.

 

This Warrant Certificate may be exchanged, upon
its surrender to the Issuer and payment of such administration fee, not exceeding $10.00, as the Issuer may require, for new Warrant Certificates
of like tenor in denominations which in the aggregate represent the number of Warrants represented hereby.

 

If this Warrant Certificate is lost, stolen, mutilated
or destroyed, the Issuer may on such reasonable terms as it may in its discretion impose, including but not limited to the payment of
any administration fee, not exceeding $10.00, and the provision of any indemnity by the Holder, issue and countersign a new Warrant Certificate
of like tenor, denomination and date as the Warrant Certificate so lost, stolen, mutilated or destroyed.

 

All Warrants shall rank pari passu, notwithstanding
the actual date of issue thereof.

 

Covenants

 

The Issuer covenants and agrees that so long as
any Warrants evidenced hereby remain outstanding, it shall reserve and there shall remain unissued out of its authorized capital a sufficient
number of Common Shares to satisfy the right of purchase herein provided for and such Common Shares shall be issued as fully paid and
non-assessable Common Shares and the holders thereof shall not be liable to the Issuer or to its creditors in respect thereof.

 

The
Issuer shall use all reasonable commercial efforts to preserve and maintain its corporate existence and to ensure that the Common Shares
outstanding or issuable from time to time upon the exercise of the Warrants are listed and posted for trading on the TSX (or such
other exchange on which the Common Shares may be listed), provided that this clause shall not be construed as limiting or restricting
the Issuer from completing a consolidation, amalgamation, arrangement, takeover bid or merger that would result in the Common Shares ceasing
to be listed and posted for trading on the TSX (or such other exchange on which the Common Shares may be listed), so long as the holders
of Common Shares receive securities of an entity which is listed on a stock exchange in Canada, or cash, or the holders of the Common
Shares have approved the transaction in accordance with the requirements of applicable corporate and securities laws and the policies
of the TSX (or such other exchange on which the Common Shares may be listed). In addition, the Issuer shall make all requisite filings
under applicable securities legislation necessary to remain a reporting issuer not in default.

 

If the issuance of the Common Shares upon the
exercise of the Warrants requires any filing or registration with or approval of any securities regulatory authority or other governmental
authority or compliance with any other requirement under any law before such Common Shares may be validly issued (other than the filing
of a prospectus or similar disclosure document), the Issuer agrees to take such actions as may be necessary to secure such filing, registration,
approval or compliance, as the case may be.

 

Transfer of Warrants

 

The Warrants are transferable and the term “Warrantholder”
shall mean and include any successor, transferee or assignee of the current or any future Warrantholder. The term “Warrantholder”
shall mean and include any successor of the Warrantholder. The Warrants may be transferred by the Warrantholder completing and delivering
to the Issuer the transfer form attached hereto as Schedule “B”.

 

Holding of Warrants

 

The Issuer may treat the Holder as the absolute
owner of the Warrants represented hereby for all purposes, and the Issuer shall not be affected by any notice or knowledge to the contrary
except where the Issuer is required to take notice by statute or by order of a court of competent jurisdiction.

 

     

     

    

 

Nothing in this Warrant Certificate or in the
holding of a Warrant evidenced hereby shall be construed as conferring upon the Holder any right or interest whatsoever as a shareholder
of the Issuer or entitle the Holder to any right or interest in respect of any Common Shares except as herein expressly provided.

 

Resale Restrictions and Legending Of Certificates

 

The Warrants have been, and the Common Shares
will be, issued pursuant to an exemption (an “Exemption”) from the registration and prospectus requirements of applicable
securities law. To the extent that the Issuer relies on such Exemption, the Common Shares may be subject to restrictions on resale and
transferability contained in applicable securities laws.

 

If any of the Securities are subject to a hold
period, or any other restrictions on resale and transferability, the Issuer may place a legend on the certificates representing the Securities
as may be required under applicable securities laws, or as it may otherwise deem necessary or advisable.

 

Any certificate representing Common Shares issued
upon the exercise of this Warrant prior to the date which is four months and one day after the Issue Date will bear the following legends:

 

UNLESS PERMITTED UNDER SECURITIES LEGISLATION,
THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY BEFORE AUGUST 31, 2018.

 

and

 

THE SECURITIES REPRESENTED BY THIS CERTIFICATE
ARE LISTED ON THE TORONTO STOCK EXCHANGE (“TSX”); HOWEVER, THE SECURITIES CANNOT BE TRADED THROUGH 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.

 

provided that at any time subsequent to the date
which is four months and one day after the date hereof any certificate representing such Common Shares may be exchanged for a certificate
bearing no such legends.

 

Capital Adjustments

 

Subject
to approval of the TSX (or such other exchange on which the Common Shares may be listed), if at any time after the date hereof
and prior to the expiry of the Warrants, and provided that any Warrants remain unexercised, there shall be:

 

		(a)	a reclassification of the Common Shares, a change in the Common Shares into other shares or securities,
a subdivision or consolidation of the Common Shares into a greater or lesser number of Common Shares, or any other capital reorganization,
or

 

		(b)	a consolidation, amalgamation or merger of the Issuer with or into any other corporation other than a
consolidation, amalgamation or merger which does not result in any reclassification of the outstanding Common Shares or a change of the
Common Shares into other shares or securities,

 

(any of such events being called a “Capital
Reorganization”) any Holders who shall thereafter acquire Common Shares pursuant to the Warrant shall be entitled to receive, at
no additional cost, and shall accept in lieu of the number of Common Shares to which such Holder was theretofore entitled to acquire upon
such exercise, the aggregate number of shares, other securities or other property which such Holder should have been entitled to receive
as a result of such Capital Reorganization if, on the effective date or record date thereof as the case may be, the Holder had been the
registered holder of the number of Common Shares to which such Holder was theretofore entitled to acquire upon exercise of the Warrants.
If determined appropriate by the Issuer acting reasonably, appropriate adjustments shall be made in the application of the provisions
set forth herein with respect to the rights and interests of the Holder relative to a Capital Reorganization, to the end that the provisions
set forth herein shall correspond as nearly as may be reasonably possible to the effect of the Capital Reorganization in relation to any
shares, other securities or other property thereafter deliverable upon the exercise of any Warrants.

 

     

     

    

 

In case at any time:

 

		(a)	the Issuer shall pay any dividend payable in stock upon its Common Shares or make any distribution to
the holders of its Common Shares;

 

		(b)	the Issuer shall offer for subscription pro rata to the holders of its Common Shares any additional shares
or stock of any class or other rights;

 

		(c)	there shall be any subdivision, consolidation, capital reorganization, or reclassification of the capital
stock of the Issuer, or merger, amalgamation or arrangement of the Issuer with, or sale of all or substantially all of its assets to,
another corporation; or

 

		(d)	there shall be a voluntary or involuntary dissolution, liquidation or winding-up of the Issuer,

 

the Issuer shall give to the Holder at least twenty
days’ prior written notice of the date on which the books of the Issuer shall close or a record shall be established for such dividend,
distribution or subscription rights, or for determining rights to vote with respect to such subdivision, consolidation, capital reorganization,
reclassification, merger, amalgamation, arrangement, sale, dissolution, liquidation or winding-up, and in the case of any such subdivision,
consolidation, capital reorganization, reclassification, merger, amalgamation, arrangement, sale, dissolution, liquidation or winding-up,
at least twenty days’ prior written notice of the date when the same shall take place. Such notice in accordance with the foregoing
clause shall also specify, in the case of any such dividend, distribution or subscription rights, the date on which the holders of Common
Shares shall be entitled thereto, and such notice in accordance with the foregoing shall also specify, in the case of any such subdivision,
consolidation, capital reorganization, reclassification, merger, amalgamation, arrangement, sale, dissolution, liquidation or winding-up,
the date on which the holders of Common Shares shall be entitled to exchange their Common Shares for securities or other property deliverable
upon such subdivision, consolidation, capital reorganization, reclassification, merger, amalgamation, arrangement, sale, dissolution,
liquidation or winding-up as the case may be. Each such written notice shall be given by first class mail, postage prepaid, addressed
to the Holder at its address as shown on the books of the Issuer.

 

In case the Issuer, after the date hereof, shall
take any action affecting any securities of the Issuer, other than as previously set out herein, which in the opinion of the directors
would materially affect the rights and interests of the Holder hereunder, the number of Common Shares or other securities which shall
be issuable on the exercise of the Warrants shall be adjusted in such manner, if any, and at such time as the directors, in their sole
discretion, may determine to be equitable in the circumstances, provided that no such adjustment will be made unless all necessary regulatory
approvals, if any, have been obtained. In the event of any question arising with respect to any adjustment provided for herein, such question
shall be conclusively determined by a firm of chartered accountants appointed by the Issuer at its sole discretion (who may be the Issuer’s
auditors) and any such determination shall be binding upon the Issuer and the Holder.

 

No
adjustment shall be made in respect of any event described herein if the Holder is entitled to participate in such event on the same terms,
without amendment, as if the Holder had exercised the Warrants prior to or on the effective date or record date of such event, subject
to the written consent of the TSX (or such other exchange on which the Common Shares may be listed). The adjustments provided for
herein are cumulative and such adjustments shall be made successively whenever an event referred to herein shall occur, subject to the
limitations provided for herein. No adjustment shall be made in the number or kind of Shares or other securities which may be acquired
on the exercise of a Warrant unless it would result in a change of at least one-tenth of a Share or other security. Any adjustment which
may by reason of this paragraph not be required to be made shall be carried forward and then taken into consideration in any subsequent
adjustment.

 

Notwithstanding any adjustments provided for herein
or otherwise, the Issuer shall not be required, upon the exercise of any Warrants, to issue fractional Common Shares or other securities
in satisfaction of its obligations hereunder and, except as provided for herein, any fractions shall be eliminated. To the extent that
the Holder would otherwise be entitled to acquire a fraction of a Common Share or other security, such right may be exercised in respect
of such fraction only in combination with other rights which in the aggregate entitle the Holder to acquire a whole number of Common Shares
or other securities. The Holder shall be entitled, upon the elimination of any fraction of a Common Share or other security, to be paid
in cash for the fair market value for the securities so eliminated, always provided that the Issuer shall not be required to make any
payment if for less than $10.00.

 

     

     

    

 

Representation and Warranty

 

The Issuer hereby represents and warrants
with and to the Holder that the Issuer is duly authorized and has the corporate and lawful power and authority to create and issue
this Warrant and the Common Shares issuable upon the exercise hereof and perform its obligations hereunder and that this Warrant
represents a valid, legal and binding obligation of the Issuer enforceable in accordance with its terms.

 

Miscellaneous Provisions

 

Any delivery or surrender of documents shall be
valid and effective if delivered personally or if sent by registered letter postage prepaid, and any notice shall be valid and effective
if made in writing and transmitted as aforementioned or if transmitted by facsimile with confirmed receipt, in each case addressed to:

in postal services, any delivery or surrender of documents or notice sent by mail shall not be deemed to have been effectively made or
received until it is actually delivered. The Issuer and the Holder may from time to time change their address for service hereunder by
notice in writing delivered in one of the foregoing manners.

 

Except as herein provided, any and all of the
rights conferred upon the Holder herein may be enforced by the Holder through appropriate legal proceedings. No recourse under or upon
any covenant, obligation or agreement herein contained shall be had against any shareholder, officer or director of the Issuer, either
directly or through the Issuer, it being expressly agreed and declared that the obligations under the Warrants are solely corporate obligations
of the Issuer and no personal liability whatsoever shall attach to or be incurred by the shareholders, officers or directors of the Issuer
in respect thereof. This Warrant Certificate shall be binding upon the Issuer and its successors.

 

This Warrant shall be governed in accordance with
the laws of British Columbia and the laws of Canada applicable therein. The parties hereby attorn to the jurisdiction of the courts of
British Columbia in the event of any dispute hereunder. Time shall be of the essence hereof.

 

The Issuer shall be entitled to rely on delivery
of an executed Certificate by electronic means, and acceptance by the Holder of such electronic Certificate (including, without limitation
by facsimile or email delivery) shall be legally effective between the Holder and the Issuer in accordance with the terms hereof.
