August 25, 2026 (the “Time of Expiry”) at a purchase price of US$0.16 per Warrant Share for each Warrant represented
hereby after which time the Warrants represented hereby shall expire (the price at which one Warrant Share of the Corporation may be purchased
hereunder from time to time being hereinafter referred to as the “Exercise Price”), all subject to adjustment as hereinafter
provided in this Warrant certificate. The Warrants may he exercised by surrendering this Warrant certificate, together with a subscription
form in the form attached as Schedule “A” hereto duly completed and executed and a wire transfer, certified cheque, bank draft

notify the Holder, acting reasonably. The Corporation will then issue that number of Warrant Shares specified in the subscription form
as fully paid and non-assessable Warrant Shares.


 


2.                            Partial Exercise. The Holder may subscribe for and purchase less than the full number of Warrant Shares entitled to
be subscribed for and purchased hereunder. In the event that the Holder subscribes for and purchases less than the full number of Warrant
Shares entitled to be subscribed for and purchased under this Warrant certificate prior to the Time of Expiry. the Corporation shall issue
a new Warrant certificate to the Holder in substantially the same form as this Warrant certificate representing such unexercised Warrants,
with appropriate changes.


 


3.                            Delivery of Warrant Shares. Within three business days of receipt of this Warrant certificate together with a subscription

or money order in lawful money of Canada payable to or to the order of the Corporation, the Corporation shall deliver or cause to be delivered
to the Holder certificates or direct registration system statements representing the Warrant Shares subscribed for and purchased by the
Holder hereunder, and a replacement Warrant certificate, if any.


 


4.                            No Rights of Shareholders. Nothing contained in this Warrant certificate (or in the Warrants evidenced hereby) shall
be construed as conferring upon the Holder any right or interest whatsoever as a holder of common shares of the Corporation (the “Common
Shares”) or any other right or interest except as herein expressly provided.


 


5.                            Adjustment of Subscription and Purchase Rights. From and after the date hereof, the Exercise Price and the number of
Warrant Shares deliverable upon the exercise of the Warrants will be subject to adjustment in the events and in the following manner:


 


		(a)	In case of any reclassification of the Common Shares or change of the Common Shares into other shares,
or in case of the consolidation, arrangement, merger, reorganization or amalgamation of the Corporation with or into any other corporation
or entity which results in any reclassification of the Common Shares or a change of the Common Shares into other shares, or in case of
any transfer of the undertaking or assets of the Corporation as an entirety or substantially as an entirety to another person (any such
event being hereinafter referred to as a “Reclassification of Shares”), at any time prior to the Time of Expiry, the
Holder shall, after the effective date of such Reclassification of Shares and upon exercise of the right to purchase Warrant Shares hereunder,
be entitled to receive, and shall accept, in lieu of the number of Warrant Shares to which the Holder was theretofore entitled upon such
exercise, the kind and amount of shares and other securities or property which the Holder would have been entitled to receive as a result
of such Reclassification of Shares if, on the effective date of such Reclassification of Shares, the Holder had been the registered holder
of the number of Warrant Shares to which the Holder was theretofore entitled upon such exercise. If necessary, appropriate adjustments
shall be made in the application of the provisions set forth in this Section 5 with respect to the rights and interests thereafter of
the Holder of this Warrant certificate to the end that the provisions set forth in this Section 5 shall thereafter correspondingly be
made applicable as nearly as may be reasonable in relation to any shares or other securities or property thereafter deliverable upon the
exercise of the Warrants evidenced hereby.

(b)           If
and whenever at any time prior to the Time of Expiry the Corporation shall:


 


(i)            subdivide, re-divide or change the Common Shares into a greater number of shares;


 


(ii)           reduce, combine or consolidate the Common Shares into a lesser number of shares; or


 


(iii)          fix a record date for the issue o£ or distribution to, or issue Common Shares, Participating Shares or Convertible Securities
(as such terms are defined in Section 13) to all or substantially all of the holders of Common Shares by way of a stock dividend or other
distribution on the Common Shares payable in Common Shares, Participating Shares or Convertible Securities,


 


(any such event being hereinafter
referred to as “Capital Reorganization”) and any such event results in an adjustment in the Exercise Price pursuant
to paragraph (c), the number of Warrant Shares purchasable pursuant to the Warrants evidenced hereby shall be adjusted contemporaneously
with the adjustment of the Exercise Price by multiplying the number of Warrant Shares theretofore purchasable on the exercise thereof
by a fraction the numerator of which shall he the Exercise Price in effect immediately prior to such adjustment and the denominator of
which shall be the Exercise Price resulting from such adjustment.


 


		(c)	If and whenever at any time prior to the Time of Expiry, the Corporation shall
engage in a Capital Reorganization, the Exercise Price shall, on the effective date, in the case of a subdivision or consolidation, or
on the record date, in the case of a stock dividend, be adjusted by multiplying the Exercise Price in effect on such effective date or
record date by a fraction: (A) the numerator of which shall be the number of Common Shares and Participating Shares outstanding before
giving effect to such Capital Reorganization; and (B) the denominator of which is the number of Common Shares and Participating Shares
outstanding after giving effect to such Capital Reorganization. The number of Common Shares and Participating Shares outstanding shall
include the deemed conversion into or exchange for Common Shares or Participating Shares of any Convertible Securities distributed by
way of stock dividend or other such distribution. Such adjustment shall be made successively whenever any event referred to in this paragraph
shall occur.



 


		(d)	Any issue of Common Shares, Participating Shares or Convertible Securities by way of a stock dividend
or other such distribution shall be deemed to have been made on the record date thereof for the purpose of calculating the number of outstanding
Common Shares under paragraphs (e) and (f).



 


		(e)	If and whenever at any time prior to the Time of Expiry, the Corporation shall fix a record date for the
issuance or distribution of rights, options or warrants to all or substantially all the holders of Common Shares entitling them, for a
period expiring not more than 45 days after such record date, to subscribe for or purchase Common Shares, Participating Shares or Convertible
Securities at a price per share (or having a conversion or exchange price per share) of less than 95% of the Current Market Price of the
Common Shares on such record date (any such event being hereinafter referred to as a “Rights Offering”), the Exercise Price
shall be adjusted immediately after such record date so that it shall equal the price determined by multiplying the Exercise Price in
effect on such record date by a fraction:



 






     


    - 3 - 


    

 


(i)          the numerator of which shall be the aggregate of (A) the number of Common Shares outstanding on such record date; and (B) a number
determined by dividing whichever of the following is applicable by the Current Market Price of the Common Shares on the record date: (1)
the amount obtained by multiplying the number of Common Shares or Participating Shares which the holders of Common Shares are entitled
to subscribe for or purchase by the subscription or purchase price; or (2) the amount obtained by multiplying the maximum number of Common
Shares or Participating Shares which the holders of Common Shares are entitled to receive on the conversion or exchange of the Convertible
Securities by the conversion or exchange price per share; and


 


(ii)         the denominator of which shall be the aggregate of: (A) the number of Common Shares outstanding on such record date; and (B) whichever
of the following is applicable: (1) the number of Common. Shares or Participating Shares which the holders of Common Shares are entitled
to subscribe for or purchase; or (2) the maximum number of Common Shares or Participating Shares which the holders of Common Shares are
entitled to receive on the conversion or exchange of the Convertible Securities,


 


and if any such event results in
an adjustment in the Exercise Price, the number of Warrant Shares purchasable pursuant to the Warrants evidenced hereby shall be adjusted
contemporaneously with the adjustment of the Exercise Price by multiplying the number of Warrant Shares theretofore purchasable on the
exercise thereof by a fraction the numerator of which shall be the Exercise Price in effect immediately prior to such adjustment and the
denominator of which shall be the Exercise Price resulting from such adjustment.


 


Any Warrant Shares owned by or held
for the account of the Corporation shall be deemed not to be outstanding for the purpose of any such computation. Such adjustment shall
be made successively whenever such a record date is fixed.


 


To the extent that such Rights Offering
is not so made or any such rights, options or warrants are not exercised prior to the expiration thereof, the Exercise Price and the number
of Warrant Shares purchasable pursuant to the Warrants evidenced hereby shall then be readjusted to the Exercise Price and number of Warrant
Shares which would then be in effect if such record date had not been fixed or if such expired rights, options or warrants had not been
issued.


 


		(f)	If and whenever at any time prior to the Time of Expiry, the
Corporation shall fix a record date for



 


the issue or distribution to all or substantially
all the holders of Warrant Shares of:


 


		(i)	shares of any class, whether of the Corporation or any other corporation;



 


		(ii)	rights, options or warrants;



 


		(iii)	evidences of indebtedness; or



 


		(iv)	other assets or property;



 


and if such issue or distribution
does not constitute a Capital Reorganization or a Rights Offering or does not consist of rights, options or warrants entitling the holders
of Common Shares to subscribe for or purchase Common Shares, Participating Shares or Convertible Securities for a period expiring not
more than 45 days after such record date and at a price per share (or having a conversion or exchange price per share) of at least 95%
of the Current Market Price of the Common Shares on such record date (any such non-excluded event being hereinafter referred to as a “Special
Distribution”) the Exercise Price shall be adjusted immediately after such record date so that it shall equal the price determined
by multiplying the Exercise Price in effect on such record date by a fraction: (I) the numerator of which shall be the amount by which
(A) the amount obtained by multiplying the number of Common Shares outstanding on such record date by the Current Market Price of the
Common Shares on such record date, exceeds (B) the fair market value (as determined. by the directors of the Corporation, which determination
shall be conclusive, but subject to Toronto Stock Exchange (“TSX”) approval) to the holders of such Common Shares of
such Special Distribution; and (H) the denominator of which shall be the total number of Common Shares outstanding on such record date
multiplied by such Current Market Price, and if any such event results in an adjustment in the Exercise Price, the number of Warrant Shares
purchasable pursuant to the Warrants evidenced hereby shall be adjusted contemporaneously with the adjustment of the Exercise Price by
multiplying the number of Warrant Shares theretofore purchasable on the exercise thereof by a fraction the numerator of which shall be
the Exercise Price in effect immediately prior to such adjustment and the denominator of which shall be the Exercise Price resulting from
such adjustment.


 






     


    - 4 - 


    

 


Any Common Shares owned by or held
for the account of the Corporation shall be deemed not to be outstanding for the purpose of any such computation. Such adjustment shall
be made successively whenever such a record date is fixed.


 


To the extent that such Special Distribution
is not so made or any such rights, options or warrants are not exercised prior to the expiration thereof, the Exercise Price and the number
of Warrant Shares purchasable pursuant to the Warrants evidenced hereby shall then be readjusted to the Exercise Price and number of Warrant
Shares which would then be in effect if such record date had not been fixed or if such expired rights, options or warrants had not been
issued.


 


		(g)	No adjustment in the Exercise Price will be made pursuant to
this Section 5 in respect of the issue from time to time of Common Shares issuable from time to time as dividends paid in the ordinary
course to holders of Common Shares who exercise an option or election to receive substantially equivalent dividends in Common Shares
in lieu of receiving a cash dividend, and any such issue will be deemed not to be a Common Share reorganization.



 


		(h)	In any case in which this Section 5 shall require that an adjustment
shall become effective immediately after a record date for an event referred to herein, the Corporation may defer, until the occurrence
of such event, issuing to the Holder, upon the exercise of the Warrants evidenced hereby after such record date and before the occurrence
of such event, the additional Warrant Shares issuable upon such exercise by reason of the adjustment required by such event; provided,
however, that the Corporation shall deliver to the Holder an appropriate instrument evidencing the Holder's right to receive such additional
Warrant Shares upon the occurrence of the event requiring such adjustment and the right to receive any distributions made on such additional
Warrant Shares on and after such exercise.



 


		(i)	The adjustments provided for in this Section 5 are cumulative,
and shall, in the case of adjustments to the Exercise Price, be computed to the nearest one tenth of one cent and shall apply (without
duplication) to successive Reclassifications of Shares, Capital Reorganizations, Rights Offerings and Special Distributions; provided
that, notwithstanding any other provision of this Section 5, no adjustment of the Exercise Price shall be required unless such adjustment
would require an increase or decrease of at least 1% of the Exercise Price then in effect (except upon a consolidation of the outstanding
Common Shares) (provided, however, that any adjustments which by reason of this paragraph are not required to be made shall be carried
forward and taken into account in any subsequent adjustment).



 


		(j)	No adjustment in the number of Warrant Shares which may be purchased
upon exercise of the Warrants evidenced hereby or in the Exercise Price shall be made pursuant to this Warrant certificate if the Holder
is entitled to participate in such event on the same terms mutatis mutandis as if the Holder had exercised the Warrants evidenced hereby
for Warrant Shares prior to the effective date or record date of such event. Any such participation will be subject to TSX approval.

		(k)	If at any time prior to the Time of Expiry the Corporation will
take any action affecting the Common Shares, other than an action or an event described above in this Section 5, which in the opinion
of the directors of the Corporation acting reasonably, would have a material adverse effect upon the rights of the Holder under this
Warrant certificate, the Exercise Price and/or the number of Warrant Shares purchasable under this Warrant certificate will be adjusted
in such manner and at such time as the directors may determine to be equitable in the circumstances, but subject to TSX approval.



 


		(1)	In the event of any question arising with respect to the adjustments provided in this Section 5, such
question shall conclusively be determined by the Corporation's auditors and such determination, absent manifest error, shall be binding
upon the Corporation and the Holder.



 


		(in)	As a condition precedent to the taking of any action which would require an adjustment in the subscription
rights pursuant to the Warrants, including the Exercise Price and the number of such classes of shares or other securities or property
which are to be received upon the exercise thereof, the Corporation shall take all corporate action which may, in the opinion of counsel,
be necessary in order that the Corporation has reserved and there will remain unissued out of its authorized capital a sufficient number
of Warrant Shares for issuance upon the exercise of the Warrants evidenced hereby, and that the Corporation may validly and legally issue
as fully paid and non-assessable, all the shares of such classes or other securities, or may validly and legally distribute the property
which the Holder is entitled to receive on the full exercise thereof in accordance with the provisions hereof



 


		(n)	At least 21 days prior to the effective date or record date, as the case may be, of any event which requires
an adjustment in the subscription rights pursuant to this Warrant certificate, including the Exercise Price and the number and classes
of shares or other securities or property which are to be received upon the exercise thereof the Corporation shall give notice to the
Holder of the particulars of such event and the required adjustment. If it is not reasonably practicable for the Corporation to give 21
days' notice as aforesaid, the Corporation will give as much notice as is reasonably practicable in the circumstances.



 


		(o)	Subject to requisite TSX approval, the Corporation may, at its option, at any time during the term of
the Warrants, reduce the then current Exercise Price to any amount deemed appropriate by the board of directors of the Corporation.



 


6.                             Representations and Warranties of the Corporation. The Corporation hereby represents and warrants that it is authorized
to create and issue the Warrants and covenants and agrees that it will cause the Warrant Shares from time to time subscribed for and purchased
in the manner provided in this Warrant certificate and the certificate representing such Warrant Shares to be issued and that, at all
times prior to the Time of Expiry, it will reserve and there will remain unissued a sufficient number of Warrant Shares to satisfy the
right of purchase provided for in this Warrant certificate. All Warrant Shares which are issued upon the exercise of the right of purchase
provided in this Warrant certificate, upon payment therefor of the amount at which such Warrant Shares may be purchased pursuant to the
provisions of this Warrant certificate, shall be and be deemed to be fully paid and non-assessable shares and free from all taxes, liens
and charges with respect to the issue thereof The Corporation hereby represents and warrants that this Warrant certificate is a valid
and enforceable obligation of the Corporation, enforceable in accordance with the provisions of this Warrant certificate.


 


7.                             No Fractional Warrant Shares. The Corporation shall not be required to issue fractional Warrant Shares upon the exercise
of the Warrants evidenced hereby. If any fractional interest in a Warrant Share would be deliverable upon the exercise of the Warrants
evidenced hereby, the Corporation shall, in lieu of delivering any certificate for such fractional interest, round such fractional interest
down to the nearest whole Warrant Share.
