    	 	- 7 -	 

     

    

 

		2.2	Form and Terms of Warrants

 

(1)           The
Warrants may be issued in either certificated or uncertificated form. Notwithstanding the foregoing, all Warrants issued in the
United States or to, or for the account or benefit of, a person in the United States or U.S. Persons that are Accredited Investors
shall be in certificated form only. The Warrant Certificates shall be substantially in the form attached as Schedule A hereto and
dated as of the date of issue, subject to the provisions of this Indenture, with such additions, variations and changes as may
be required or permitted by the terms of this Indenture, and to give effect to any Warrants not being issued as Uncertificated
Warrants, and which may from time to time be agreed upon by the Warrant Agent and the Company, and shall have such distinguishing
letters and numbers as the Company may, with the approval of the Warrant Agent, prescribe. Except as hereinafter provided in this
Article 2, all Warrants shall, save as to denominations, be of like tenor and effect. The Warrant Certificates may be engraved,
printed, lithographed, photocopied or be partially in one form or another, as the Company may determine. No change in the form
of the Warrant Certificate shall be required by reason of any adjustment made pursuant to this Article 2 in the number and/or
class of securities or type of securities that may be acquired pursuant to the exercise of Warrants.

 

(2)           Each
Warrant authorized to be issued hereunder shall entitle the registered holder thereof to acquire (subject to sections 2.13,
2.14 and 2.15) upon due exercise and upon the transaction instruction or due execution of the exercise form endorsed on the
Warrant Certificate, as applicable, or other instrument of exercise in such form as the Warrant Agent and/or the Company may from

(3)           Fractional
Warrants shall not be issued or otherwise provided for and shall be disregarded for all purposes and no cash amount will be payable
in lieu thereof. If the exercise of any Warrant would result in a fraction of a Common Share being issued to any person, any such
fraction shall be rounded down to the next whole number of Common Shares and no cash amount will be payable in lieu thereof.

 

    	 	- 8 -	 

     

    

 

(4)           Notwithstanding
any other provision herein, if at any time on or after the date that is 18 months after September 20, 2017, the closing trading
price of the Common Shares on the TSXV (or if the Common Shares are not listed on the TSXV, then on such other recognized Canadian
stock exchange on which the Common Shares are then listed and primarily traded) equals or exceeds $2.50 for a period of at least
10 consecutive trading days, the Company shall be entitled, within 15 days of the occurrence of such event, to accelerate the Time
of Expiry of the Warrants to a period ending on the date that is 20 days from the date that notice of such acceleration (the “Acceleration
Notice”) is given to the Warrant Agent and to the Warrantholders pursuant to a press release issued by the Company, with
the new Time of Expiry specified in such Acceleration Notice. From and after the new Time of Expiry specified in such Acceleration
Notice, no Warrants may be issued or exercised, and all unexercised Warrants shall be void and of no effect following the new Time
of Expiry. For greater certainty, the new Time of Expiry specified in an Acceleration Notice shall not be later than 5:00 p.m.
(Toronto Time) on September 20, 2020.

 

		2.3	Signing of Warrant Certificates

 

Warrant Certificates
shall be signed by any one of the directors or executive officers of the Company and may, but need not be under the corporate seal
of the Company or a reproduction thereof. The signature of any such director or officer may be mechanically reproduced in facsimile
or other electronic format and Warrant Certificates bearing such facsimile or other electronic format signatures shall be binding
upon the Company as if they had been manually signed by such director or officer. Notwithstanding that the person whose manual
or electronic signature appears on any Warrant Certificate as a director or executive officer may no longer hold office at the
date of issue of the Warrant Certificate or at the date of certification or delivery thereof, any Warrant Certificate signed as
aforesaid shall, subject to section 2.4, be valid and binding upon the Company and the registered holder thereof will be entitled
to the benefits of this Indenture.

 

		2.4	Authentication or Certification by the Warrant Agent

 

(1)           No
Warrant Certificate shall be issued or, if issued, shall be valid for any purpose or entitle the registered holder to the benefit
hereof or thereof until it has been certified by manual signature by or on behalf of the Warrant Agent and such certification by
the Warrant Agent shall be conclusive evidence as against the Company that the Warrant so certified has been duly issued hereunder
and the holder is entitled to the benefits hereof.

 

(2)           No
NCI deposit in the Book-Based System shall be made or, if made, shall be valid for any purposes or entitle the holder to the benefits
hereof and thereof until it has been Authenticated by the Warrant Agent and such Authentication shall be conclusive evidence as
against the Company that the NCI deposit so made has been duly issued hereunder and that the holder is entitled to the benefits
hereof and thereof.

 

(3)           The
certification of the Warrant Agent on the Warrant Certificates issued hereunder, or the Authentication of the Warrant Agent of
the NCI deposit in the Book-Based System made hereunder, as applicable, shall not be construed as a representation or warranty
by the Warrant Agent as to the validity of this Indenture or the Warrant Certificates (except the due certification thereof) or
the NCI deposit (except the due Authentication thereof) as applicable, and the Warrant Agent shall in no respect be liable or answerable
for the use made of the Warrant Certificate or NCI deposit, as applicable, or any of them or of the consideration therefor except
as otherwise specified herein.

or interest whatsoever as a shareholder, including but not limited to the right to vote at, to receive notice of, or to attend
meetings of shareholders or any other proceedings of the Company, nor entitle the holder to any right or interest in respect thereof
except as herein and in the Warrants expressly provided.

 

		2.6	Issue in Substitution for Lost Warrant Certificates

 

(1)           If
any Warrant Certificates issued and certified under this Indenture shall become mutilated or be lost, destroyed or stolen, the
Company, subject to applicable law, and subsection 2.6(2), shall issue and thereupon the Warrant Agent shall certify and deliver
a new Warrant Certificate of like denomination, date and tenor as the one mutilated, lost, destroyed or stolen in exchange for,
in place of and upon cancellation of such mutilated Warrant Certificate, or in lieu of and in substitution for such lost, destroyed
or stolen Warrant Certificate, and the substituted Warrant Certificate shall be substantially in the form set out in Schedule A
hereto and Warrants evidenced by it will entitle the holder thereof to the benefits hereof and shall rank equally in accordance
with its terms with all other Warrant Certificates issued or to be issued hereunder.

 

(2)           The
applicant for the issue of a new Warrant Certificate pursuant to this section 2.6 shall bear the reasonable cost of the issue
thereof and in the case of mutilation shall, as a condition precedent to the issue thereof, deliver to the Warrant Agent the mutilated
Warrant Certificate, and in the case of loss, destruction or theft shall, as a condition precedent to the issue thereof, furnish
to the Company and to the Warrant Agent such evidence of ownership and of the loss, destruction or theft of the Warrant Certificate
so lost, destroyed or stolen as shall be satisfactory to the Company and to the Warrant Agent in their sole discretion and such
applicant may be required to furnish an indemnity and surety bond in amount and form satisfactory to the Company and the Warrant
Agent in their sole discretion and shall pay the reasonable charges of the Company and the Warrant Agent in connection therewith.

 

		2.7	Warrants to Rank Pari Passu

 

All Warrants shall rank
pari passu with all other Warrants, whatever may be the actual date of issue of the Warrants.

 

		2.8	Registration and Transfer of Warrants

 

(1)           The
Warrant Agent will create and keep at the principal stock transfer offices of the Warrant Agent in the City of Toronto, Ontario:

 

		(a)	a register of holders in which shall be entered in alphabetical order the names and addresses of
the holders of Warrants and particulars of the Warrants held by them and the Warrant Agent shall be entitled to rely on such register
in connection with the exchange, transfer or exercise of any Warrant(s) pursuant to the terms of this Indenture or the terms thereof;
and

 

    	 	- 10 -	 

     

    

 

 

		(b)	a register of transfers in which all transfers of Warrants and the date and other particulars of
each such transfer shall be entered.

 

(2)          No
transfer of any Warrant will be valid unless entered on the register of transfers referred to in subsection 2.8(1), and, in
the case of a Warrant Certificate, upon surrender to the Warrant Agent of the Warrant Certificate evidencing such Warrant, and
a duly completed and executed transfer form endorsed on the Warrant Certificate executed by the registered holder or his executors,
administrators or other legal representatives or his attorney duly appointed by an instrument in writing in form and execution
satisfactory to the Warrant Agent, if applicable, and, upon compliance with such requirements and such other reasonable requirements
as the Warrant Agent may prescribe, such transfer will be recorded on the register of transfers by the Warrant Agent.

 

(3)           In
the case of a Warrant Certificate, the transferee of any Warrant will, after surrender to the Warrant Agent of the Warrant Certificate
evidencing such Warrant as required by subsection 2.8(2) and upon compliance with all other conditions in respect thereof
required by this Indenture or by law, be entitled to be entered on the register of holders referred to in subsection 2.8(1)
as the owner of such Warrant free from all equities or rights of set-off or counterclaim between the Company and the transferor
or any previous holder of such Warrant, except in respect of equities or rights of which the Company is required to take notice
by statute or by order of a court of competent jurisdiction.

 

(4)           The
Company will be entitled, and may direct the Warrant Agent, to refuse to recognize any transfer, or enter the name of any transferee,
of any Warrant on the registers referred to in subsection 2.8(1), if such transfer would constitute a violation of (a) the
Securities Laws of any applicable jurisdiction or the rules, regulations or policies of any regulatory authority having jurisdiction,
(b) any restrictive legend on such Warrant or (c) any applicable representations and warranties made by the Warrantholder in a
QIB Letter executed by such Warrantholder in connection with the Offering. The Warrant Agent is entitled to assume compliance with
all applicable Securities Laws unless otherwise notified in writing by the Company. No duty shall rest with the Warrant Agent to
determine compliance of the transferee or transferor of any Warrant with applicable Securities Laws.

 

(5)           Any
Warrant issued to a transferee upon transfers contemplated by this section 2.8 shall bear the appropriate legend(s) as set
forth in subsection 2.20(2), if applicable.

 

(6)           If
a Warrant tendered for transfer bears the legend set forth in subsection 2.20(2), the Warrant Agent shall not register such
transfer unless the transferor has provided the Warrant Agent with the Warrant Certificate and complies with the requirements of
the said subsection 2.20(2).

 

(7)           Warrants,
in certificated form, bearing the legend set forth in subsection 2.20(2) shall not be offered, sold or otherwise transferred
except (A) to the Company, (B) outside the United States in accordance with Rule 904 of Regulation S and in
compliance with applicable local securities laws and regulations, (C) in compliance with the exemption from the registration
requirements under the U.S. Securities Act provided by (i) Rule 144A, if available, or (ii) Rule 144 under
the U.S. Securities Act, if available, (D) in another transaction that does not require registration under the U.S. Securities Act,
and in each case, in accordance with any applicable state securities laws in the United States, provided that in the case of transfers
pursuant to (C)(ii) or (D) above, the Company has received, prior to such transfer, an opinion of counsel or other
evidence of exemption reasonably satisfactory to the Company. Warrants, in uncertificated form, held by a Warrantholder in the
United States or a U.S. Person that is a Qualified Institutional Buyer may be offered, sold or otherwise transferred only
in accordance with this section 2.8(7)(A) or (B), as provided for in the QIB Letter for such Warrantholder.

 

    	 	- 11 -	 

     

    

 

		2.9	Registers Open for Inspection

 

The registers referred
to in subsection 2.8(1) shall be open at all reasonable times during business hours on a Business Day for inspection by the
Company or any Warrantholder. The Warrant Agent shall, from time to time when requested to do so in writing by the Company and
upon payment of its reasonable fees, furnish the Company with a list of the names and addresses of holders of Warrants entered
in the register of holders kept by the Warrant Agent and showing the number of Warrants held by each such holder.

 

		2.10	Exchange of Warrant Certificates

 

(1)           Warrant
Certificates may, upon compliance with the reasonable requirements of the Warrant Agent, be exchanged for Warrant Certificates
in any other authorized denomination representing in the aggregate an equal number of Warrants as the number of Warrants represented
by the Warrant Certificates being exchanged. The Company shall sign and the Warrant Agent shall certify, in accordance with sections 2.3
and 2.4, all Warrant Certificates necessary to carry out the exchanges contemplated herein.

 

(2)           Warrant
Certificates may be exchanged only at the principal stock transfer offices of the Warrant Agent in the City of Toronto, Ontario
or at any other place that is designated by the Company with the approval of the Warrant Agent. Any Warrant Certificates tendered
for exchange shall be surrendered to the Warrant Agent and cancelled.

 

(3)           Except
as otherwise herein provided, the Warrant Agent may charge Warrantholders requesting an exchange a reasonable sum for each Warrant
Certificate issued; and payment of such charges and reimbursement of the Warrant Agent or the Company for any and all taxes or
governmental or other charges required to be paid shall be made by the party requesting such exchange as a condition precedent
to such exchange.

 

		2.11	Ownership of Warrants

 

The Company and the Warrant
Agent and their respective agents may deem and treat the registered holder of any Warrant as the absolute owner of the Warrant
represented thereby for all purposes and the Company and the Warrant Agent and their respective agents shall not be affected by
any notice or knowledge to the contrary except as required by statute or order of a court of competent jurisdiction. The holder
of any Warrant shall be entitled to the rights evidenced by that Warrant free from all equities or rights of set-off or counterclaim
between the Company and the original or any intermediate holder thereof and all persons may act accordingly and the receipt by
any holder of the Warrant Shares or monies obtainable pursuant to the exercise of the Warrant shall be a good discharge to the
Company and the Warrant Agent for the same and neither the Company nor the Warrant Agent shall be bound to inquire into the title
of any holder.

 

    	 	- 12 -	 

     

    

 

		2.12	Book-Based System Warrants

 

(1)           Except
as described above, and except for Warrants issued in the United States or to, or for the account or benefit of, a person in the
United States or U.S. Persons that are Accredited Investors, or as may be directed by the Company, registration of interests in
and transfers of Warrants shall be made only through the Book-Based System. Other than for those Warrants issued in the United
States or to, or for the account or benefit of, a person in the United States or U.S. Persons that are Accredited Investors, or
as may be directed by the Company, the Warrants will be evidenced by a non-certificated inventory (“NCI”) deposit
though the Book-Based System for an amount representing the aggregate number of such Warrants outstanding from time to time.

 

(2)           Transfers
of beneficial ownership in any Warrant represented by an NCI deposit will be effected only (i) with respect to the interest of
a CDS Participant, through records maintained by CDS or its nominee for such Warrants, and (ii) with respect to the interest of
any person other than a CDS Participant, through records maintained by CDS Participants.

 

(3)          The
rights of Beneficial Owners who hold security entitlements in respect of Warrants through the Book-Based System shall be limited
to those established by applicable law and agreements between CDS and CDS Participants and between such CDS Participants and Beneficial
Owners who hold security entitlements in respect of Warrants through the Book-Based System and must be exercised through a CDS
Participant in accordance with the rules and procedures of CDS.

 

(4)           If
any of the following events occurs:

 

		(a)	CDS or the Company has notified the Warrant Agent that (A) CDS is unwilling or unable to continue
as depository or (B) CDS ceases to be a clearing agency in good standing under applicable laws and, in either case, the Company
is unable to locate a qualified successor depository within 90 days of delivery of such notice;

 

		(b)	the Company has determined, in its sole discretion, to terminate the Book-Based System in respect
of such Uncertificated Warrants and has communicated such determination to the Warrant Agent in writing;

 

		(c)	the Company or CDS is required by applicable law to take the action contemplated in this subsection;
or

 

		(d)	the Book-Based System administered by CDS ceases to exist,

 

then one or more definitive fully registered
Warrant Certificates shall be executed by the Company and certified and delivered by the Warrant Agent to CDS in exchange for the
Uncertificated Warrants form held by CDS.

 

    	 	- 13 -	 

     

    

 

Fully registered Warrant
Certificates issued and exchanged pursuant to this subsection shall be registered in such names and in such denominations as CDS
shall instruct the Warrant Agent, provided that the aggregate number of Warrants represented by such Warrant Certificates shall
be equal to the aggregate number of Uncertificated Warrants so exchanged. Upon exchange of Uncertificated Warrants for one or more
Warrant Certificates in definitive form, such Uncertificated Warrants shall be cancelled by the Warrant Agent.

 

(5)          Notwithstanding
anything in this Indenture in terms of an NCI deposit, neither the Company nor the Warrant Agent nor any agent thereof shall have
any responsibility or liability for:

 

		(a)	the records maintained by CDS relating to any ownership interests or any other interests in the
Warrants or the depository system maintained by CDS, or payments made on account of any ownership interest or any other interest
of any person in any Warrant represented by any NCI deposit (other than CDS or its nominee);

 

		(b)	maintaining, supervising or reviewing any records of CDS or any CDS Participant relating to any
such interest; or

 

		(c)	any advice or representation made or given by CDS or those contained in this Indenture that relate
to the rules and regulations of CDS or any action to be taken by CDS on its own direction or at the direction of any CDS Participant.

 

		2.13	Adjustment of Exchange Basis

 

Subject to section 2.14,
the Exchange Basis shall be subject to adjustment from time to time in the events and in the manner provided as follows:

 

(1)           If
and whenever, at any time after the date hereof and prior to the Time of Expiry, the Company shall:

 

		(i)	issue Common Shares or securities exchangeable for or convertible into Common Shares to all or
substantially all the holders of the Common Shares as a stock dividend or other distribution (other than a distribution of Warrant
Shares upon exercise of the Warrants or pursuant to the exercise, conversion or exchange of securities of the Company outstanding
as of the date hereof), or

 

		(ii)	subdivide, redivide or change its then outstanding Common Shares into a greater number of Common
Shares, or

 

		(iii)	reduce, combine or consolidate its then outstanding Common Shares into a lesser number of Common
Shares,

 

(any of such events in these paragraphs (i),
(ii) or (iii) being called a “Common Share Reorganization”), then the Exchange Basis in effect on the effective
date of such subdivision, redivision or change, or reduction, combination or consolidation, or on the record date of such stock
dividend or other distribution, as the case may be, shall be adjusted by multiplying the Exchange Basis in effect immediately prior
to such effective or record date by a fraction:

 

    	 	- 14 -	 

     

    

 

		(a)	the numerator of which shall be the total number of Common Shares outstanding on such date immediately
after giving effect to such Common Share Reorganization (including, in the case where securities exercisable, exchangeable for
or convertible into Common Shares are distributed, the number of Common Shares that would have been outstanding had such securities
been exercised, or exchanged for or converted into Common Shares on such record date, assuming in any case where such securities
are not then convertible, exercisable or exchangeable but subsequently become so, that they were convertible, exercisable or exchangeable
on the record date on the basis upon which they first become convertible, exercisable or exchangeable), and

 

		(b)	the denominator of which shall be the total number of Common Shares outstanding on such date before
giving effect to such Common Share Reorganization.

 

The resulting
product, adjusted to the nearest 1/100th, shall thereafter be the Exchange Basis until further adjusted as provided in this Article 2.

 

Any Common Shares owned by or
held for the account of the Company or any of its Subsidiaries or a partnership in which the Company is directly or indirectly
a party to will be deemed not to be outstanding for the purpose of any computation. To the extent that any adjustment in the Exchange
Basis occurs pursuant to this subsection 2.13(1) as a result of the fixing by the Company of a record date for the distribution
of securities exchangeable or exercisable for or convertible into Common Shares and the Common Share Reorganization does not occur
or any conversion, exercise or exchange rights are not fully converted, exercised or exchanged, the Exchange Basis shall be readjusted
immediately after the expiry of any relevant exchange or conversion right or the termination of the Common Share Reorganization,
as the case may be, to the Exchange Basis that would then be in effect, based upon the number of Common Shares actually issued
and remaining issuable after such expiry and shall be further readjusted in such manner upon the expiry of any further such right.

 

(2)           If
and whenever, at any time after the date hereof and prior to the Time of Expiry, the Company shall fix a record date for the distribution
to all or substantially all of the holders of its outstanding Common Shares of rights, options or warrants entitling them, for
a period expiring not more than 45 days after such record date, to subscribe for or purchase Common Shares, or securities
exchangeable or exercisable for or convertible into Common Shares, at a price per share to the holder (or at an exchange, exercise
or conversion price per share) of less than 95% of the Current Market Price on such record date (any of such events being called
a “Rights Offering”), then the Exchange Basis shall be adjusted effective immediately after such record date
for the Rights Offering by multiplying the Exchange Basis in effect immediately prior to such record date by a fraction:

 

    	 	- 15 -	 

     

    

 

		(a)	the numerator of which shall be the number of Common Shares which would be outstanding after giving
effect to the Rights Offering (assuming the exercise of all of the rights, options or warrants under the Rights Offering and assuming
the exchange, exercise or conversion into Common Shares of all exchangeable, exercisable or convertible securities issued upon
exercise of such rights, options or warrants, if any), and

 

		(b)	the denominator of which shall be the aggregate of:

 

		(i)	the total number of Common Shares outstanding as of the record date for the Rights Offering, and

 

		(ii)	a number of Common Shares determined by dividing

 

		(A)	the amount equal to the aggregate consideration payable on the exercise of all of the rights, options
and warrants under the Rights Offering plus the aggregate consideration, if any, payable on the exchange, exercise or conversion
of the exchangeable or convertible securities issued upon exercise of such rights, options or warrants (assuming the exercise of
all rights, options and warrants under the Rights Offering and assuming the exchange or conversion of all exchangeable or convertible
securities issued upon exercise of such rights, options and warrants);

 

by

 

		(B)	the Current Market Price as of the record date for the Rights Offering.

 

The resulting product, adjusted to the
nearest 1/100th, shall thereafter be the Exchange Basis until further adjusted as provided in this Article 2. Any Common Shares
owned by or held for the account of the Company or any of its Subsidiaries or a partnership in which the Company is directly or
indirectly a party to will be deemed not to be outstanding for the purpose of any computation. If, at the date of expiry of the
rights, options or warrants subject to the Rights Offering, less than all the rights, options or warrants have been exercised,
then the Exchange Basis shall be readjusted effective immediately after the date of expiry to the Exchange Basis which would have
been in effect on the date of expiry if only the rights, options or warrants issued had been those exercised. If at the date of
expiry of the rights of exchange, exercise or conversion of any securities issued pursuant to the Rights Offering less than all
of such securities have been exchanged or exercised for, or converted into, Common Shares, then the Exchange Basis shall be readjusted
effective immediately after the date of expiry to the Exchange Basis which would have been in effect on the date of expiry if only
the exchangeable, exercisable or convertible securities issued had been those securities actually exchanged or exercised for or
converted into Common Shares.

 

    	 	- 16 -	 

     

    

 

(3)           If
and whenever, at any time after the date hereof and prior to the Time of Expiry, the Company shall fix a record date for the issuance
or distribution to all or substantially all the holders of its outstanding Common Shares of:

 

		(i)	shares of the Company of any class other than Common Shares; or

 

		(ii)	rights, options or warrants to acquire Common Shares or securities exchangeable or exercisable
for or convertible into Common Shares; or

 

		(iii)	evidences of indebtedness; or

 

		(iv)	cash, securities or any property or other assets,

 

and if such issuance or distribution does
not constitute a Common Share Reorganization or a Rights Offering (any of such non-excluded events being herein called a “Special
Distribution”), the Exchange Basis shall be adjusted effective immediately after the record date for the Special Distribution
by multiplying the Exchange Basis in effect on such record date by a fraction:

 

		(a)	the numerator of which shall be the number of Common Shares outstanding on such record date multiplied
by the Current Market Price on such record date, and

 

		(b)	the denominator of which shall be:

 

		(A)	the product of the number of Common Shares outstanding on such record date and the Current Market
Price on such record date,

 

less

 

		(B)	the fair market value, as determined by action by the board of directors acting reasonably and
in good faith (whose determination shall, absent manifest error, be conclusive), to the holders of the Common Shares of the shares,
rights, options, warrants, evidences of indebtedness or property or other assets issued or distributed in the Special Distribution,

 

provided that no such adjustment shall
be made if the result of such adjustment would be to decrease the Exchange Basis in effect immediately before such record date.
The resulting product, adjusted to the nearest 1/100th, shall thereafter be the Exchange Basis until further adjusted as provided
in this Article 2. Any shares owned by or held for the account of the Company or its Subsidiaries or a partnership of which
the Company is directly or indirectly a party to shall be deemed not to be outstanding for the purpose of any such computation.

 

    	 	- 17 -	 

     

    

 

(4)           If
and whenever, at any time after the date hereof and prior to the Time of Expiry, there shall be a reclassification of the Common
Shares at any time outstanding or change or exchange of the Common Shares into other shares or into other securities (other than
a Common Share Reorganization), or a consolidation, amalgamation, plan of arrangement or merger of the Company with or into any
other corporation or other entity (other than a consolidation, amalgamation, plan of arrangement 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 a transfer (other
than to a Subsidiary) of the undertaking or assets of the Company as an entirety or substantially as an entirety to another corporation
or other entity (any of such events being herein called a “Capital Reorganization”), any Warrantholder who thereafter
shall exercise his right to receive Warrant Shares pursuant to Warrant(s) shall be entitled to receive, and shall accept in lieu
of the number of Warrant Shares to which such holder was theretofore entitled upon such exercise, the aggregate number of shares,
other securities or other property resulting from the Capital Reorganization which such holder would 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 Warrantholder
had been the registered holder of the number of Warrant Shares to which such holder was theretofore entitled upon exercise. If
appropriate, adjustments shall be made as a result of any such Capital Reorganization in the application of the provisions set
forth in this Article 2 with respect to the rights and interests thereafter of Warrantholders to the end that the provisions
set forth in this Article 2 shall thereafter correspondingly be made applicable as nearly as may reasonably be in relation
to any shares, other securities or other property thereafter deliverable upon the exercise of any Warrant. Any such adjustment
shall be made by and set forth in an indenture supplemental hereto approved by the directors and by the Warrant Agent and entered
into pursuant to the provisions of this Indenture and shall for all purposes be conclusively deemed to be an appropriate adjustment.

 

(5)          Any
adjustment to the Exchange Basis as set forth herein (except resulting from a Capital Reorganization) shall also include a corresponding
adjustment to the Exercise Price which shall be calculated by multiplying the Exercise Price by a fraction: (a) the numerator of
which shall be the Exchange Basis prior to the adjustment, and (b) the denominator of which shall be the Exchange Basis after the
adjustment.

 

		2.14	Rules Regarding Calculation of Adjustment of Exchange Basis

 

For the purposes of section 2.13:

 

(1)          The
adjustments provided for in section 2.13 shall be cumulative and such adjustments shall be made successively whenever an event
referred to in section 2.13 shall occur, subject to the following subsections of this section 2.14.

 

(2)           No
adjustment in the: (a) Exchange Basis shall be required unless such adjustment would result in a change of at least 0.01 of
a Warrant Share based on the prevailing Exchange Basis; or (b) Exercise Price shall be required unless such adjustment would
result in a change of at least 1%, provided that any adjustments which, except for the provisions of this subsection, would otherwise
have been required to be made, shall be carried forward and taken into account in any subsequent adjustment.

 

(3)           No
adjustment in the Exchange Basis shall be made in respect of any event described in section 2.13, other than the events referred
to in paragraphs (ii) and (iii) of subsection (1) thereof, if Warrantholders are entitled to participate in such
event on the same terms, mutatis mutandis, as if Warrantholders had exercised their Warrants prior to or on the effective date
or record date of such event, any such participation being subject to regulatory approval.

 

    	 	- 18 -	 

     

    

 

(4)           No
adjustment in the Exchange Basis shall be made pursuant to section 2.13 in respect of the issue from time to time of Warrant
Shares purchasable on exercise of the Warrants or pursuant to the exercise, conversion or exchange of securities of the Company
outstanding as of the date hereof.

 

(5)           If
a dispute shall at any time arise with respect to adjustments provided for in section 2.13, such dispute shall, absent manifest
error, be conclusively determined by the Company’s Auditors, or if they are unable or unwilling to act, by such other firm
of independent chartered accountants as may be selected by the directors and any further determination, absent manifest error,
shall be binding upon the Company, the Warrant Agent and the Warrantholders.

 

(6)           If
the Company shall set a record date to determine the holders of the Common Shares for the purpose of entitling them to receive
any dividend or distribution or any subscription or purchase rights and shall, thereafter and before the distribution to such shareholders
of any such dividend, distribution, or subscription or purchase rights, legally abandon its plan to pay or deliver such dividend,
distribution, or subscription or purchase rights, then no adjustment in the Exchange Basis shall be required by reason of the setting
of such record date.

 

(7)           In
the absence of a resolution of the directors fixing a record date for a Rights Offering or Special Distribution, the Company shall
be deemed to have fixed as the record date therefor the date on which the Rights Offering or Special Distribution is effected.

 

(8)           If
the purchase price provided for in any Rights Offering (the “Rights Offering Price”) is decreased, the Exchange
Basis shall forthwith be changed so as to increase the Exchange Basis to such Exchange Basis as would have been obtained had the
adjustment to the Exchange Basis made pursuant to subsection 2.13(2) upon the issuance of such Rights Offering been made upon
the basis of the Rights Offering Price as so decreased, provided that the provisions of this subsection shall not apply to any
decrease in the Rights Offering Price resulting from provisions in any such Rights Offering designed to prevent dilution if the
event giving rise to such decrease in the Rights Offering Price itself requires an adjustment to the Exchange Basis pursuant to
the provisions of section 2.13.

 

(9)           As
a condition precedent to the taking of any action that would require any adjustment in any of the subscription rights pursuant
to any of the Warrants, including the Exchange Basis, the Company shall take any corporate action which may, in the opinion of
counsel, be necessary in order that the Company have unissued and reserved in its authorized capital and may validly and legally
issue as fully paid and non-assessable all the shares or other securities that all the holders of such Warrants are entitled to
receive on the exercise of all the subscription rights attaching thereto in accordance with the provisions thereof.

 

(10)         The
Warrant Agent shall be entitled to act and rely on any adjustment calculations by the Company or the Company’s Auditors.

 

    	 	- 19 -	 

     

    

 

		2.15	Postponement of Subscription

 

In any case where the
application of section 2.13 results in an increase in the number of Common Shares that are issuable upon exercise of the Warrants
taking effect immediately after the record date for a specific event, if any Warrant is exercised after that record date and prior
to completion of such specific event, the Company may postpone the issuance to the Warrantholder of the Warrant Shares to which
he is entitled by reason of such adjustment, but such Warrant Shares shall be so issued and delivered to that holder upon completion
of that event, with the number of such Warrant Shares calculated on the basis of the number of Warrant Shares on the date that
the Warrant was exercised, adjusted for completion of that event and the Company shall deliver to the person or persons in whose
name or names the Warrant Shares are to be issued an appropriate instrument evidencing the right of such person or persons to receive
such Warrant Shares and the right to receive any dividends or other distributions which, but for the provisions of this section 2.15,
such person or persons would have been entitled to receive in respect of such Warrant Shares from and after the date that the Warrant
was exercised in respect thereof.

 

		2.16	Notice of Adjustment

 

(1)          At
least 14 days prior to the effective date or record date, as the case may be, of any event which requires or might require
adjustment pursuant to section 2.13, the Company shall:

 

		(a)	file with the Warrant Agent a certificate of the Company specifying the particulars of such event
(including the record date or the effective date for such event) and, if determinable, the required adjustment and the computation
of such adjustment; and

 

		(b)	give notice to the Warrantholders of the particulars of such event (including the record date or
the effective date for such event) and, if determinable, the required adjustment.

 

(2)           In
case any adjustment for which a notice in subsection 2.16(1) has been given is not then determinable, the Company shall promptly
after such adjustment is determinable:

 

		(a)	file with the Warrant Agent a computation of such adjustment; and

 

		(b)	give notice to the Warrantholders of the adjustment.

 

(3)           The
Warrant Agent may, absent manifest error, act and rely upon certificates and other documents filed by the Company pursuant to this
section 2.16 for all purposes of the adjustment.

 

		2.17	No Action after Notice

 

The Company covenants
with the Warrant Agent that it will not take any other corporate action which might deprive a Warrantholder of the opportunity

Article 3

EXERCISE OF WARRANTS

 

		3.1	Method of Exercise of Warrants

 

(1)          The
registered holder of any Warrant may exercise the rights thereby conferred on him to acquire all or any part of the Warrant Shares
to which such Warrant entitles the holder, by surrendering the Warrant Certificate representing such Warrants to the Warrant Agent
at any time prior to the Time of Expiry at its principal stock transfer offices in the City of Toronto, Ontario (or at such additional
place or places as may be decided by the Company from time to time with the approval of the Warrant Agent), with a duly completed
and executed exercise form of the registered holder or his executors, administrators or other legal representative or his attorney
duly appointed by an instrument in writing in the form and manner satisfactory to the Warrant Agent, substantially in the form
endorsed on the Warrant Certificate specifying the number of Warrant Shares subscribed for together with a certified cheque, bank
draft or money order in lawful money of Canada, payable to or to the order of the Company in an amount equal to the Exercise Price
multiplied by the number of Warrant Shares subscribed for. A Warrant Certificate with the duly completed and executed exercise
form and payment of the Exercise Price shall be deemed to be surrendered only upon personal delivery thereof to or, if sent by
mail or other means of transmission, upon actual receipt thereof by the Warrant Agent.

 

(2)           Any
exercise form referred to in subsection 3.1(1) shall be signed by the Warrantholder, or his executors, or administrators or
other legal representative or his attorney duly appointed by an instrument in writing in the form and manner satisfactory to the
Warrant Agent, shall specify the person(s) in whose name such Warrant Shares are to be issued, the address(es) of such person(s)
and the number of Warrant Shares to be issued to each person, if more than one is so specified. If any of the Warrant Shares subscribed
for are to be issued to (a) person(s) other than the Warrantholder, the signatures set out in the exercise form referred to
in subsection 3.1(1) shall be guaranteed by a Canadian Schedule I chartered bank or a medallion signature guarantee from
a member of a recognized Signature Medallion Guarantee Program and (b) the Warrantholder shall pay to the Company or the Warrant
Agent all applicable transfer or similar taxes and the Company shall not be required to issue or deliver certificates evidencing
Warrant Shares unless or until such Warrantholder shall have paid to the Company or the Warrant Agent on behalf of the Company
the amount of such tax or shall have established to the reasonable satisfaction of the Company that such tax has been paid or that
no tax is due.

 

    	 	- 23 -	 

     

    

 

(3)           If,
at the time of exercise of the Warrants, in accordance with the provisions of subsection 3.1(1), there are any trading restrictions
on the Warrant Shares pursuant to Securities Laws or stock exchange requirements, the Company shall, on the advice of counsel,
endorse any certificates representing the Warrant Shares to such effect. The Warrant Agent is entitled to assume compliance with
all Securities Laws unless otherwise notified in writing by the Company.

 

(4)           A
Beneficial Owner who desires to exercise his Uncertificated Warrants, must do so by causing a CDS Participant to deliver to CDS
(at its office in the City of Toronto), on behalf of the Beneficial Owner at any time prior to the Time of Expiry, a written notice
of the Beneficial Owner’s intention to exercise Warrants (the “Exercise Notice”). Forthwith upon receipt
by CDS of such notice, as well as payment for the Exercise Price, CDS shall deliver to the Warrant Agent confirmation of its intention
to exercise Warrants (the “Confirmation”) in a manner acceptable to the Warrant Agent, including by electronic
means through the Book-Based System. CDS will initiate the exercise by way of the Confirmation and forward the aggregate Exercise
Price electronically to the Warrant Agent and the Warrant Agent will execute the exercise by issuing to CDS through the Book-Based
System the Warrant Shares to which the exercising Beneficial Owner is entitled pursuant to the exercise. Any expense associated
with the preparation and delivery of Exercise Notices will be for the account of the Beneficial Owner exercising the Warrants.

 

By causing a CDS Participant
to deliver notice to CDS, a Beneficial Owner shall be deemed to have irrevocably surrendered his Warrants so exercised and appointed
such CDS Participant to act as his or her exclusive settlement agent with respect to the exercise and the receipt of Warrant Shares
in connection with the obligations arising from such exercise.

 

Any notice which CDS
determines to be incomplete, not in proper form or not duly executed shall for all purposes be void and of no effect and the exercise
to which it relates shall be considered for all purposes not to have been exercised thereby. A failure by a CDS Participant to
exercise or to give effect to the settlement thereof in accordance with the Beneficial Owner’s instructions will not give
rise to any obligations or liability on the part of the Company or Warrant Agent to the CDS Participant or the Beneficial Owner.

 

		3.2	No Fractional Warrant Shares

 

Under no circumstances
shall the Company be obliged to issue any fractional Warrant Shares or any cash or other consideration in lieu thereof upon the
exercise of one or more Warrants. To the extent that the holder of one or more Warrants would otherwise have been entitled to receive
on the exercise or partial exercise thereof a fraction of a Warrant Share, that holder may exercise that right in respect of the
fraction only in combination with another Warrant or Warrants that in the aggregate entitle the holder to purchase a whole number
of Warrant Shares; otherwise fractional Warrant Shares shall be rounded down to the nearest whole number of Warrant Shares without
compensation therefor.

 

    	 	- 24 -	 

     

    

 

		3.3	Effect of Exercise of Warrants

 

(1)           Upon
compliance by the Warrantholder with the provisions of section 3.1, the Warrant Shares subscribed for shall be deemed to have
been issued and the person to whom such Warrant Shares are to be issued shall be deemed to have become the holder of record of
such Warrant Shares on the Exercise Date unless the transfer registers of the Company for the Common Shares shall be closed on
such date, in which case the Warrant Shares subscribed for shall be deemed to have been issued and such person shall be deemed
to have become the holder of record of such Warrant Shares on the date on which such transfer registers are reopened.

 

(2)           Within
three Business Days following the due exercise of a Warrant pursuant to section 3.1 and forthwith after the Time of Expiry,
the Warrant Agent shall deliver to the Company a notice setting forth the particulars of all Warrants exercised, if any, and the
persons in whose names the Warrant Shares are to be issued (as applicable) and the addresses of such holders of the Warrant Shares.

 

(3)           Within
three Business Days of the due exercise of a Warrant pursuant to section 3.1, the Company shall cause the Transfer Agent to
issue, within such three Business Day period, to CDS through the Book-Based System the Warrant Shares (which shall include Warrant
Shares issued to a Purchaser that is a Qualified Institutional Buyer) to which the exercising Warrantholder is entitled pursuant
to the exercise or mail to the person in whose name the Warrant Shares so subscribed for are to be issued, as specified in the
exercise form completed on the Warrant Certificate, at the address specified in such exercise form, a certificate or certificates
for the Warrant Shares to which the Warrantholder is entitled and, if applicable, shall cause the Warrant Agent to mail a Warrant
Certificate representing any Warrants not then exercised.

 

		3.4	Cancellation of Warrants

 

All Warrants surrendered
to the Warrant Agent pursuant to sections 2.6, 2.8(2), 2.10, 2.18 or 3.1 shall be cancelled by the Warrant Agent and
the Warrant Agent shall record the cancellation of such Warrants on the register of holders maintained by the Warrant Agent pursuant
to subsection 2.8(1). The Warrant Agent shall, if required by the Company, furnish the Company with a certificate identifying
the Warrants so cancelled. All Warrants that have been duly cancelled shall be without further force or effect whatsoever.

 

		3.5	Subscription for less than Entitlement

 

The holder of any Warrant
may subscribe for and purchase a whole number of Warrant Shares that is less than the number that the holder is entitled to purchase
pursuant to a surrendered Warrant. In such event, the holder thereof shall be entitled to receive a new Warrant Certificate, if
applicable, in respect of the balance of Warrants that were not then exercised, such new Warrant Certificate to contain the same
legend as provided for in subsection 2.20(2) if applicable.

 

    	 	- 25 -	 

     

    

 

		3.6	Expiration of Warrant

 

After the Time of Expiry,
all rights under any Warrant in respect of which the right of subscription and purchase herein and therein provided for shall not
theretofore have been exercised shall wholly cease and terminate and such Warrant shall be void and of no effect.

 

		3.7	Prohibition on Exercise by U.S. Persons; Exception

 

(1)           Warrants
may not be exercised within the United States or by or on behalf of, or for the account or benefit of, any U.S. Person or
any person in the United States except in compliance with this section 3.7. The Warrant Agent shall be entitled to rely upon the
registered address of the Warrantholder as set forth in such Warrantholder’s register for the purchase of Units in determining
whether the address is in the United States or the Warrantholder is a U.S. Person.

 

(2)           Any
holder which exercises any Warrants represented by a Warrant Certificate shall provide to the Company either:

 

		(a)	a written certification that such holder (i) at the time of exercise of the Warrants is not
in the United States; (ii) is not a U.S. Person and is not exercising the Warrants on behalf of a U.S. Person or
person in the United States; (iii) did not execute or deliver the exercise form for the Warrants in the United States; and

by checking Box 1 in the Exercise Form attached to the Warrant, as provided for in Schedule A hereof);

 

		(b)	a written certification that the holder (i) purchased the Warrants as a part of the Units
in the Offering; (ii) is exercising the Warrants solely for its own account or for the benefit of a U.S. Person or a
person in the United States for whose account such holder acquired the Warrants as a part of the Units in the Offering and for
whose account such holders exercises sole investment discretion; (iii) was and is, and any beneficial purchaser for whose
account such holder acquired the Warrant and is exercising the Warrants was and is an Accredited Investor and/or Qualified Institutional
Buyer both on the date the Units were purchased in the Offering and on the Exercise Date; and (iv) the representations and
warranties made by the holder or any beneficial purchaser, as the case may be, to the Company in such holder’s U.S. Subscription
Agreement remain true and correct on the Exercise Date (which written certification shall be deemed delivered by checking Box 2
in the Exercise Form attached to the Warrant, as provided for in Schedule A hereof); or

 

		(c)	a written opinion of counsel of recognized standing in form and substance satisfactory to the Company
to the effect that an exemption from the registration requirements of the U.S. Securities Act and applicable state securities
laws is available for the issuance of the Warrant Shares issuable on exercise of the Warrants.

 

    	 	- 26 -

or if the individual so nominated is not present within 15 minutes after the time fixed for the holding of the meeting, the
Warrantholders present in person or by proxy shall appoint an individual present to be chairman of the meeting. The chairman of
the meeting need not be a Warrantholder.

question submitted to a meeting and after a vote by show of hands, a poll shall be taken in such manner as the chairman shall direct.
Questions other than those required to be determined by extraordinary resolution shall be decided by a majority of the votes cast
on the poll. On a show of hands, every person who is present and entitled to vote, whether as a Warrantholder or as proxy for one
or more absent Warrantholders, or both, shall have one vote. On a poll, each Warrantholder present in person or represented by
a proxy duly appointed by instrument in writing shall be entitled to one vote in respect of each whole Warrant then held by him.

		6.11	Meaning of “Extraordinary Resolution”

 

(1)          The
expression “extraordinary resolution” when used in this Indenture means, subject as hereinafter in this section 6.11
and in section 6.14 provided, a resolution proposed at a meeting of Warrantholders duly convened for that purpose and held
in accordance with the provisions of this Article 6 at which there are present in person or by proxy at least two Warrantholders
representing at least 20% of the aggregate number of all the then outstanding Warrants and passed by the affirmative votes of Warrantholders
representing not less than 662⁄3% of the aggregate number of all the then outstanding Warrants represented at the meeting and
voted on the poll for such resolution.

at any meeting called for the purpose of passing an extraordinary resolution, Warrantholders representing at least 20% of the aggregate
number of all the then outstanding Warrants are not present in person or by proxy within one-half hour after the time appointed
for the meeting, then the meeting, if convened by Warrantholders or on a Warrantholders’ Request, shall be dissolved; but
in any other case it shall stand adjourned to such day, being not less than 10 Business Days later, and to such place and time
as may be appointed by the chairman. Not less than three Business Days prior notice shall be given of the time and place of such

in person or represented by proxy shall form a quorum and may transact the business for which the meeting was originally convened
and a resolution proposed at such adjourned meeting and passed by the requisite vote as provided in subsection 6.11(1) shall
be an extraordinary resolution within the meaning of this Indenture notwithstanding that Warrantholders representing at least 20%
of all the then outstanding Warrants are not present in person or represented by proxy at such adjourned meeting.

on an extraordinary resolution shall always be given on a poll and no demand for a poll on an extraordinary resolution shall be
necessary.

and to the extent that any provision of this Indenture limits, qualifies or conflicts with a mandatory requirement of Applicable
Legislation, such mandatory requirement shall prevail.

 

(2)          The
Company and the Warrant Agent agree that each will at all times in relation to this Indenture and any action to be taken hereunder
observe and comply with and be entitled to the benefit of Applicable Legislation.

(2)           In
the exercise of the rights and duties prescribed or conferred by the terms of this Indenture, the Warrant Agent shall act honestly
and in good faith and shall exercise the degree of care, diligence and skill that a reasonably prudent warrant agent would exercise
in comparable circumstances. No provision of this Indenture shall be construed to relieve the Warrant Agent from, or require any
other person to indemnify the Warrant Agent against liability for its own gross negligence, wilful misconduct, bad faith or fraud.

 

(3)          The
Warrant Agent shall not be bound to do or take any act, action or proceeding for the enforcement of any of the obligations of the
Company under this Indenture unless and until it shall have received a Warrantholders’ Request specifying the act, action
or proceeding that the Warrant Agent is requested to take. The obligation of the Warrant Agent to commence or continue any act,
action or proceeding for the purpose of enforcing any rights of the Warrant Agent or the Warrantholders hereunder shall be conditional
upon the Warrantholders furnishing, when required by notice in writing by the Warrant Agent, sufficient funds to commence or continue
such act, action or proceeding and an indemnity reasonably satisfactory to the Warrant Agent and its counsel to protect and hold
harmless the Warrant Agent, its officers, directors, employees, agents, successors and assigns against the costs, charges and expenses
and liabilities to be incurred thereby and any loss and damage it may suffer by reason thereof. None of the provisions contained
in this Indenture shall require the Warrant Agent to expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties or in the exercise of any of its rights or powers unless indemnified and funded as aforesaid.

 

    	 	- 36 -	 

     

    

 

(4)          The
Warrant Agent may, before commencing any act, action or proceeding, or at any time during the continuance thereof require the Warrantholders
at whose instance it is acting to deposit with the Warrant Agent the Warrants held by them, for which Warrants the Warrant Agent
shall issue receipts.

 

(5)           Every
provision of this Indenture that, by its terms, relieves the Warrant Agent of liability or entitles it to rely upon any evidence
submitted to it is subject to the provisions of Applicable Legislation, this section 8.2 and section 8.3.

 

(6)          The
Warrant Agent shall not be bound to give any notice or do or take any act, action or proceeding by virtue of the powers conferred
on it hereunder unless and until it shall have been required to do so under the terms hereof; nor shall the Warrant Agent be required
to take notice of any default hereunder, unless and until notified in writing of such default, which notice shall specifically
set out the default desired to be brought to the attention of the Warrant Agent and in the absence of such notice the Warrant Agent
may for all purposes of this Indenture conclusively assume that no default has occurred or been made in the performance or observance
of the representations, warranties and covenants, agreements or conditions herein contained. Any such notice shall in no way limit
any discretion herein given to the Warrant Agent to determine whether or not the Warrant Agent shall take action with respect to
any default.

 

(7)           In
this Indenture, whenever confirmations or instructions are required to be given to the Warrant Agent, in order to be valid, such

Legislation or as the Warrant Agent may reasonably require by written notice to the Company.

 

(2)           In
the exercise of its rights and duties hereunder, the Warrant Agent may, if it is acting in good faith, act and rely absolutely
as to the truth of the statements and the accuracy of the opinions expressed therein, upon statutory declarations, opinions, reports,
written requests, consents, or orders of the Company, certificates of the Company or other evidence furnished to the Warrant Agent
pursuant to any provision hereof or of Applicable Legislation or pursuant to a request of the Warrant Agent. The Warrant Agent
shall be under no responsibility in respect of the validity of this Indenture or the execution and delivery hereof by or on behalf
of the Company or in respect of the validity or the execution of any Warrant Certificate by the Company and issued hereunder, nor
shall it be responsible for any breach by the Company of any covenant or condition contained in this Indenture or in any such Warrant
Certificate; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation
of any securities to be issued upon the right to acquire provided for in this Indenture and/or in any Warrant or as to whether
any securities will when issued be duly authorized or be validly issued and fully paid and non-assessable.

opinion, report, notice, request, consent, order, letter, or other paper document believed by it to be genuine and to have been
signed, sent or presented by or on behalf of the proper party or parties. The Warrant Agent has sole discretion and shall be protected
in acting and relying upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order,
letter or other paper document received in facsimile or e-mail form.

 

(6)           The
Warrant Agent may employ or retain such counsel, accountants, engineers, appraisers or other experts or advisers as it may reasonably
require for the purpose of determining and discharging its duties hereunder and may pay reasonable remuneration for all services
so performed by any of them, without taxation of costs of any counsel and shall not be responsible for any misconduct on the part
of any of them who has been selected with due care by the Warrant Agent. Any reasonable remuneration paid by the Warrant Agent
shall be paid by the Company in accordance with section 4.3.

 

(7)           The
Warrant Agent may act and rely and shall be protected in acting and relying in good faith on the opinion or advice of or information
obtained from any counsel, accountant, appraiser, engineer or other expert or advisor, whether retained or employed by the Company
or the Warrant Agent, in relation to any matter arising in fulfilling its duties and obligations hereof.

 

(8)           The
Warrant Agent may, as a condition precedent to any action to be taken by it under this Indenture, require such opinions, statutory

of title, monies or other instruments that may at any time be held by the Warrant Agent subject to the duties and obligations hereof,
for the benefit of the Company, may be placed in the deposit vaults of the Warrant Agent or of any Schedule I Canadian chartered
bank for safekeeping with any such bank. All interest or other income received by the Warrant Agent in respect of such deposits

Indenture.

The Warrant Agent shall
not be required to give any bond or security in respect of the execution of the duties and obligations of this Indenture or otherwise.

 

		8.7	Protection of Warrant Agent

 

By way of supplement
to the provisions of any law for the time being relating to warrant agents, it is expressly declared and agreed as follows:

 

(1)           The
Warrant Agent shall not be liable for or by reason of any representations, statements of fact or recitals in this Indenture or
in the Warrants (except the representation contained in section 8.9 or in the certificate of the Warrant Agent on the Warrants)
or be required to verify the same and all such statements of fact or recitals are and shall be deemed to be made by the Company
(except the representation contained in section 8.9 or in the certificate of the Warrant Agent on the Warrants).

 

(2)           Nothing
herein contained shall impose any obligation on the Warrant Agent to see to or to require evidence of the registration or filing
(or renewal thereof) of this Indenture or any instrument ancillary or supplemental hereto.

 

(3)           The
Warrant Agent shall not be bound to give notice to any person or persons of the execution hereof.

    	 	- 39 -	 

     

    

 

(5)           Without
limiting any protection or indemnity of the Warrant Agent under any other provision hereof, or otherwise at law, the Company hereby
agrees to indemnify and hold harmless the Warrant Agent and its directors, officers, agents and employees from and against any
and all liabilities, losses, damages, penalties, claims, actions, suits, costs, expenses and disbursements, including reasonable
legal or advisor fees and disbursements, of whatever kind and nature which may at any time be imposed on, incurred by or asserted
against the Warrant Agent in connection with the performance of its duties and obligations hereunder, other than such liabilities,
losses, damages, penalties, claims, actions, suits, costs, expenses and disbursements arising by reason of the gross negligence,
wilful misconduct, bad faith or fraud of the Warrant Agent. This provision shall survive the resignation or removal of the Warrant
Agent, or the termination of this Indenture. The Warrant Agent shall not be under any obligation to prosecute or defend any action
or suit in respect of this Indenture which, in the opinion of its counsel, may involve it in expense or liability, unless the Company
shall, so often as required, furnish the Warrant Agent with satisfactory indemnity and funding against such expense or liability.

 

(6)           If
any of the funds provided to the Warrant Agent hereunder are received by it in the form of an uncertified cheque or bank draft,
the Warrant Agent shall delay the release of such funds and the related Warrant Shares until such uncertified cheque has cleared
the financial institution upon which the same is drawn.

 

(7)           The
forwarding of a cheque or the sending of funds by wire transfer by the Warrant Agent will satisfy and discharge the liability of
any amounts due to the extent of the sum represented thereby unless such cheque is not honoured on presentation, provided that
in the event of the non-receipt of such cheque by the payee, or the loss or destruction thereof, the Warrant Agent, upon being
furnished with reasonable evidence of such non-receipt, loss or destruction and indemnity reasonably satisfactory to it, will issue
to such payee a replacement cheque for the amount of such cheque.

 

(8)           The
Warrant Agent shall retain the right not to act and shall not be liable for refusing to act if, due to a lack of information or
for any other reason whatsoever, the Warrant Agent, in its sole judgement, determines that such act might cause it to be in non-compliance
with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline. Further, should the Warrant Agent,
in its sole judgement, determine at any time that its acting under this Warrant Indenture has resulted in its being in non-compliance
with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline, then it shall have the right
to resign on 10 days’ written notice to the Company provided: (i) that the Warrant Agent’s written notice shall
describe the circumstances of such non-compliance; and (ii) that if such circumstances are rectified to the Warrant Agent’s
satisfaction within such 10-day period, then such resignation shall not be effective.

 

(9)           The
Warrant Agent shall not be liable for any error in judgment or for any act done or step taken or omitted by it in good faith or
for any mistake, in fact or law, or for anything which it may do or refrain from doing in connection herewith except arising out

(1)           The
Warrant Agent may resign its appointment and be discharged from all further duties and liabilities hereunder by giving to the Company
not less than 60 days prior notice in writing or such shorter prior notice as the Company may accept as sufficient. The Warrantholders
by extraordinary resolution shall have the power at any time to remove the existing Warrant Agent and to appoint a new Warrant
Agent. In the event of the Warrant Agent resigning or being removed as aforesaid or being dissolved, becoming bankrupt, going into
liquidation or otherwise becoming incapable of acting hereunder, the Company shall forthwith appoint a new Warrant Agent unless
a new Warrant Agent has already been appointed by the Warrantholders; failing such appointment by the Company, the retiring Warrant
Agent or any Warrantholder may apply to a judge of the Province of Ontario at the Company’s expense, on such notice as such
judge may direct, for the appointment of a new Warrant Agent; but any new Warrant Agent so appointed by the Company or by the Court
shall be subject to removal as aforesaid by the Warrantholders. Any new Warrant Agent appointed under any provision of this section 8.8
shall be a corporation authorized to carry on the business of a transfer agent or a trust company in the Province of Ontario and,
if required by Applicable Legislation of any other province, in such other province. On any such appointment the new Warrant Agent
shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as Warrant
Agent without any further assurance, conveyance, act or deed; but there shall be immediately executed, at the expense of the Company,
all such conveyances or other instruments as may, in the opinion of counsel, be necessary or advisable for the purpose of assuring
the same to the new Warrant Agent, provided that any resignation or removal of the Warrant Agent and appointment of a successor
Warrant Agent shall not become effective until the successor Warrant Agent shall have executed an appropriate instrument accepting
such appointment and, at the request of the Company, the predecessor Warrant Agent, upon payment of its outstanding remuneration
and expenses, shall execute and deliver to the successor Warrant Agent an appropriate instrument transferring to such successor
Warrant Agent all rights and powers of the Warrant Agent hereunder and all securities, documents of title and other instruments
and all monies and properties held by the Warrant Agent hereunder.

 

(2)          Upon
the appointment of a successor Warrant Agent, the Company shall promptly notify the Warrantholders thereof in the manner provided
for in section 9.1.

 

(3)           Any
corporation into or with which the Warrant Agent may be merged or consolidated or amalgamated, or to which all or substantially
all of the corporate trust business is sold or any corporation succeeding to the stock transfer business of the Warrant Agent,
shall be the successor to the Warrant Agent hereunder without any further act on its part or of any of the parties hereto, provided
that such corporation would be eligible for appointment as a new Warrant Agent under subsection 8.8(1).

 

(4)           Any
Warrants Authenticated or certified but not delivered by a predecessor Warrant Agent may be Authenticated or certified by the new
or successor Warrant Agent in the name of the predecessor or the new or successor Warrant Agent.

		8.9	Conflict of Interest

 

(1)           The
Warrant Agent represents to the Company that at the time of execution and delivery hereof no material conflict of interest exists
which it is aware of in the Warrant Agent’s role hereunder and agrees that in the event of a material conflict of interest
arising which it becomes aware of hereafter it will, within 90 days after ascertaining that it has such a material conflict
of interest, either eliminate the same or resign its appointment hereunder. If any such material conflict of interest exists or
hereafter shall exist, the validity and enforceability of this Indenture and the Warrants shall not be affected in any manner whatsoever
by reason thereof.

 

(2)           Subject
to subsection 8.9(1), the Warrant Agent, in its personal or any other capacity, may buy, lend upon and deal in securities
of the Company and generally may contract and enter into financial transactions with the Company or any Subsidiary without being
liable to account for any profit made thereby.

 

		8.10	Acceptance of Duties and Obligations

 

The Warrant Agent hereby

CUSIP No. 74319B304

ISIN No. CA 74319B3048

 

	Warrant Certificate Number: •	Representing • Warrants to
	 	purchase Common Shares

 

THIS CERTIFIES
that, for value received, the registered holder hereof, • (the “holder”) is entitled, subject to Profound
Medical Corp.’s (the “Company”) right to accelerate the expiry time in certain circumstances, at any time
at or before 5:00 p.m. (Toronto time) on September 20, 2020 (the “Expiry Time”) to acquire, subject to
adjustment in certain events, the number of common shares (“Common Shares”) of the Company specified above,
as presently constituted, by surrendering to TSX Trust Company (the “Warrant Agent”) at its principal office
in Toronto, Ontario, this Warrant Certificate with the duly completed and executed Exercise Form endorsed on the back of this Warrant
Certificate, and accompanied by payment of $1.40 per Common Share (subject to adjustment in certain events) (the “Warrant
Exercise Price”) by certified cheque, bank draft or money order in lawful money of Canada payable to, or to the order
of, the Company at par at the above-mentioned office of the Warrant Agent. The holder of this Warrant Certificate may purchase
less than the number of Common Shares which he is entitled to purchase on the exercise of the Warrants represented by this Warrant
Certificate, in which event a new Warrant Certificate representing the Warrants not then exercised will be issued to the holder.

 

    	 	A-1	 

     

    

 

If at any time on or
after the date that is 18 months from September 20, 2017, the closing trading price of the Common Shares on the TSX Venture Exchange
(“TSXV”) (or if the Common Shares are not listed on the TSXV, then on such other recognized Canadian stock exchange
on which the Common Shares are then listed) equals or exceeds $2.50 for a period of at least 10 consecutive trading days, the Company
shall be entitled, within 15 days of the occurrence of such event, to accelerate the Expiry Time of the Warrants to a period ending
on the date that is 20 days from the date that notice of such acceleration (the “Acceleration Notice”) is provided
to the Warrant Agent and to the Warrantholders pursuant to a press release issued by the Company, with the new Expiry Time specified
in such Acceleration Notice. From and after the new Expiry Time specified in such Acceleration Notice, no Warrants may be issued
or exercised, and all unexercised Warrants shall be void and of no effect following the new Expiry Time. For greater certainty,
the new Expiry Time specified in an Acceleration Notice shall not be later than 5:00 p.m. (Toronto Time) on September 20, 2020.

 

The Warrants evidenced
hereby are exercisable on or before the Expiry Time, after which time the Warrants evidenced hereby shall be deemed to be void
and of no further force or effect.

 

This Warrant Certificate
represents Warrants of the Company issued or issuable under the provisions of a warrant indenture (which indenture together with
all other instruments supplemental or ancillary thereto is herein referred to as the “Warrant Indenture”) dated
as of September 20, 2017, between the Company and the Warrant Agent, as may be amended from time to time, which contains particulars
of the rights of the holders of the Warrants and the Company and of the Warrant Agent in respect thereof and the terms and conditions
upon which the Warrants are issued and held, all to the same effect as if the provisions of the Warrant Indenture were herein set
forth, to all of which the holder of this Warrant Certificate by acceptance hereof assents. Unless otherwise defined herein, all
capitalized terms shall have the meanings ascribed to them in the Warrant Indenture. A copy of the Warrant Indenture will be available
for inspection at the principal office of the Company in the City of Mississauga, Ontario. In the event of any conflict between
the provisions contained in this Warrant Certificate and the provisions of the Warrant Indenture, the provisions of the Warrant
Indenture shall prevail.

 

Upon acceptance hereof,
the holder hereof hereby expressly waives the right to receive any fractional Common Shares upon the exercise hereof in full or
in part and further waives the right to receive any cash or other consideration in lieu thereof. The Warrants represented by this
Warrant Certificate shall be deemed to have been surrendered, and payment by certified cheque, bank draft or money order shall
be deemed to have been made only upon personal delivery thereof or, if sent by post or other means of transmission, upon actual
receipt thereof by the Warrant Agent at its office in the City of Toronto, Ontario.

 

Upon due exercise of
the Warrants represented by this Warrant Certificate and payment of the Warrant Exercise Price, the Company shall cause to be issued
to the person(s) in whose name(s) the Common Shares so subscribed for (provided that if the Common Shares are to be issued to a
person other than the registered holder of this Warrant Certificate, the holder’s signature on the Exercise Form herein shall
be guaranteed by a Schedule I Canadian chartered bank, or by a medallion signature guarantee from a member of a recognized
Signature Medallion Guarantee Program and the holder shall pay to the Company or the Warrant Agent all applicable transfer or similar
taxes and the Company shall not be required to issue or deliver certificates evidencing the Common Shares unless or until the holder
shall have paid the Company or the Warrant Agent the amount of such tax (or shall have satisfied the Company that such tax has
been paid or that no tax is due)) are to be issued, the number of Common Shares to be issued to such person(s) and such person(s)
shall become a holder in respect of such Common Shares with effect from the date of such exercise, and upon due surrender of this
Warrant Certificate and all other documentation required, the Warrant Agent shall cause the issuance of a certificate(s) representing
such Common Shares to be issued within three Business Days after the exercise of the Warrants (or portion thereof) represented
hereby.

 

    	 	A-2	 

     

    

 

Neither the Warrants
represented by this Warrant Certificate nor the Common Shares issuable upon exercise hereof have been or will be registered under
the U.S. Securities Act or any state securities laws. The Warrants represented by this Warrant Certificate may not be
exercised within the United States or by, or for the account or benefit of, a U.S. Person (as defined by Regulation S
under the U.S. Securities Act) or a person within the United States unless registered under the U.S. Securities Act
and any applicable state securities laws or unless an exemption from such registration is available.

 

The holder acknowledges
that the Warrants represented by this Warrant Certificate and the Common Shares issuable upon exercise hereof may be offered, sold
or otherwise transferred only in compliance with all applicable securities laws.

 

No transfer of any
Warrant will be valid unless entered on the register of transfers, upon surrender to the Warrant Agent of the Warrant Certificate
evidencing such Warrant, duly endorsed by, or accompanied by a transfer form or other written instrument of transfer in form satisfactory
to the Warrant Agent executed by the registered holder or his executors, administrators or other legal representatives or his or
their attorney duly appointed by an instrument in writing in form and execution satisfactory to the Warrant Agent. Subject to the
provisions of the Warrant Indenture and upon compliance with the reasonable requirements of the Warrant Agent, Warrant Certificates
may be exchanged for Warrant Certificates representing in the aggregate an equal number of Warrants. The Company and the Warrant
Agent may treat the registered holder of this Warrant Certificate for all purposes as the absolute owner hereof. The holding of
the Warrants represented by this Warrant Certificate shall not constitute the holder hereof a holder of Common Shares nor entitle
him to any right or interest in respect thereof except as herein and in the Warrant Indenture expressly provided.

 

The Warrant Indenture
provides for adjustment in the number of Common Shares to be delivered upon exercise of the right of purchase hereby granted and
to the Warrant Exercise Price in certain events therein set forth.

 

The Warrant Indenture
contains provisions making binding upon all holders of Warrants outstanding thereunder resolutions passed at meetings of such holders
held in accordance with such provisions and instruments in writing signed by the Warrantholders holding a specified percentage
of the then outstanding Warrants.

 

The Warrants and the
Warrant Indenture shall be governed by and performed, construed and enforced in accordance with the laws of the Province of Ontario
and the federal laws of Canada applicable therein and shall be treated in all respects as Ontario contracts. Time shall be of the
essence hereof and of the Warrant Indenture.

 

    	 	A-3	 

     

    

 

The Company may from
time to time at any time prior to the Expiry Time purchase any of the Warrants by private agreement or otherwise.

 

This Warrant Certificate
shall not be valid for any purpose until it has been certified by or on behalf of the Warrant Agent for the time being under the
Warrant Indenture.

 

All dollar amounts
herein are expressed in the lawful money of Canada.

by the Warrant Agent to the Company, as applicable, in accordance with a written direction of the Company, all in accordance with

issued hereunder shall entitle the holder thereof to receive from the Company, at the Exercise Price, the number of Warrant Shares
equal to the Exchange Basis in effect on the Exercise Date.

 

		2.2	Form and Terms of Warrants

 

(1)           The
Warrants may be issued in either certificated or uncertificated form. The Warrant Certificates shall be substantially in the form
attached as Schedule A hereto and dated as of the date of issue, subject to the provisions of this Indenture, with such additions,
variations and changes as may be required or permitted by the terms of this Indenture, and to give effect to any Warrants not being
issued as Uncertificated Warrants, and which may from time to time be agreed upon by the Warrant Agent and the Company, and shall
have such distinguishing letters and numbers as the Company may, with the approval of the Warrant Agent, prescribe. Except as hereinafter
provided in this Article 2, all Warrants shall, save as to denominations, be of like tenor and effect. The Warrant Certificates
may be engraved, printed, lithographed, photocopied or be partially in one form or another, as the Company may determine. No change
in the form of the Warrant Certificate shall be required by reason of any adjustment made pursuant to this Article 2 in the
number and/or class of securities or type of securities that may be acquired pursuant to the exercise of Warrants.

 

(2)           Each
Warrant authorized to be issued hereunder shall entitle the registered holder thereof to acquire (subject to sections 2.13,
2.14 and 2.15) upon due exercise and upon the transaction instruction or due execution of the exercise form endorsed on the
Warrant Certificate, as applicable, or other instrument of exercise in such form as the Warrant Agent and/or the Company may from

or property, calculated pursuant to the provisions of sections 2.13 and 2.14, as the case may be, at any time after the
date of issuance of such Warrants and prior to the Time of Expiry, in accordance with the provisions of this Indenture.

 

(3)           Fractional
Warrants shall not be issued or otherwise provided for and shall be disregarded for all purposes and no cash amount will be payable
in lieu thereof. If the exercise of any Warrant would result in a fraction of a Common Share being issued to any person, any such
fraction shall be rounded down to the next whole number of Common Shares and no cash amount will be payable in lieu thereof.

 

    	 	- 8 -	 

     

    

 

(4)           Notwithstanding
any other provision herein, if at any time on or after the date that is 18 months after March 20, 2018, the closing trading price
of the Common Shares on the TSXV (or if the Common Shares are not listed on the TSXV, then on such other recognized Canadian stock
exchange on which the Common Shares are then listed and primarily traded) exceeds $2.80 for a period of 90 consecutive calendar
days, the Company shall be entitled, within 30 days of the occurrence of such event, to accelerate the Time of Expiry of the Warrants
to a period ending on the date that is 20 days from the date that notice of such acceleration (the “Acceleration Notice”)
is given to the Warrantholders pursuant to a press release issued by the Company, with the new Time of Expiry specified in such
Acceleration Notice. For purposes of this section, the closing trading price of the Common Shares for a day that is not a Business
Day shall be deemed to be last published closing trading price of the Common Shares. From and after the new Time of Expiry specified
in such Acceleration Notice, no Warrants may be issued or exercised, and all unexercised Warrants shall be void and of no effect
following the new Time of Expiry. The Company shall give prompt written notice of such acceleration to the Warrant Agent pursuant
to section 9.1. For greater certainty, the new Time of Expiry specified in an Acceleration Notice shall not be later than 5:00
p.m. (Toronto Time) on March 20, 2023.

of the Company or a reproduction thereof. The signature of any such director or officer may be mechanically reproduced in facsimile
or other electronic format and Warrant Certificates bearing such facsimile or other electronic format signatures shall be binding
upon the Company as if they had been manually signed by such director or officer. Notwithstanding that the person whose manual
or electronic signature appears on any Warrant Certificate as a director or executive officer may no longer hold office at the
date of issue of the Warrant Certificate or at the date of certification or delivery thereof, any Warrant Certificate signed as
aforesaid shall, subject to section 2.4, be valid and binding upon the Company and the registered holder thereof will be entitled
to the benefits of this Indenture.

 

		2.4	Authentication or Certification by the Warrant Agent

 

(1)           No
Warrant Certificate shall be issued or, if issued, shall be valid for any purpose or entitle the registered holder to the benefit
hereof or thereof until it has been certified by manual signature by or on behalf of the Warrant Agent and such certification by
the Warrant Agent shall be conclusive evidence as against the Company that the Warrant so certified has been duly issued hereunder
and the holder is entitled to the benefits hereof.

Uncertificated Warrant shall be issued or, if issued, shall be valid for any purposes or entitle the holder to the benefits hereof
and thereof until it has been Authenticated by the Warrant Agent and such Authentication shall be conclusive evidence as against
the Company that the Uncertificated Warrant has been duly issued hereunder and that the holder is entitled to the benefits hereof
and thereof.

 

    	 	- 9 -	 

     

    

 

(3)           The
certification of the Warrant Agent on the Warrant Certificates issued hereunder, or the Authentication of the Warrant Agent of
the Uncertificated Warrants made hereunder, as applicable, shall not be construed as a representation or warranty by the Warrant
Agent as to the validity of this Indenture or the Warrant Certificates (except the due certification thereof) or the Uncertificated
Warrants (except the due Authentication thereof) as applicable, and the Warrant Agent shall in no respect be liable or answerable
for the use made of the Warrant Certificates or Uncertificated Warrants, as applicable, or any of them or of the consideration
therefor except as otherwise specified herein.

 

		2.5	Warrantholder not a Shareholder, etc.

 

Nothing in this Indenture
or the holding of a Warrant evidenced by a Warrant Certificate shall be construed as conferring upon a Warrantholder any right
or interest whatsoever as a shareholder, including but not limited to the right to vote at, to receive notice of, or to attend
meetings of shareholders or any other proceedings of the Company, nor entitle the holder to any right or interest in respect thereof
except as herein and in the Warrants expressly provided.

 

		2.6	Issue in Substitution for Lost Warrant Certificates

 

(1)            If
any Warrant Certificates issued and certified under this Indenture shall become mutilated or be lost, destroyed or stolen, the
Company, subject to applicable law, and subsection 2.6(2), shall issue and thereupon the Warrant Agent shall certify and deliver
a new Warrant Certificate of like denomination, date and tenor as the one mutilated, lost, destroyed or stolen in exchange for,
in place of and upon cancellation of such mutilated Warrant Certificate, or in lieu of and in substitution for such lost, destroyed
or stolen Warrant Certificate, and the substituted Warrant Certificate shall be substantially in the form set out in Schedule A
hereto and Warrants evidenced by it will entitle the holder thereof to the benefits hereof and shall rank equally in accordance
with its terms with all other Warrant Certificates issued or to be issued hereunder.

 

(2)          The
applicant for the issue of a new Warrant Certificate pursuant to this section 2.6 shall bear the reasonable cost of the issue
thereof and in the case of mutilation shall, as a condition precedent to the issue thereof, deliver to the Warrant Agent the mutilated
Warrant Certificate, and in the case of loss, destruction or theft shall, as a condition precedent to the issue thereof, furnish
to the Company and to the Warrant Agent such evidence of ownership and of the loss, destruction or theft of the Warrant Certificate
so lost, destroyed or stolen as shall be satisfactory to the Company and to the Warrant Agent in their sole discretion and such
applicant may be required to furnish an indemnity and surety bond in amount and form satisfactory to the Company and the Warrant
Agent in their sole discretion and shall pay the reasonable charges of the Company and the Warrant Agent in connection therewith.

 

		2.7	Warrants to Rank Pari Passu

 

All Warrants shall rank
pari passu with all other Warrants, whatever may be the actual date of issue of the Warrants.

 

    	 	- 10 -	 

     

    

 

		2.8	Registration and Transfer of Warrants

 

(1)           The
Warrant Agent will create and keep at the principal stock transfer offices of the Warrant Agent in the City of Toronto, Ontario:

 

		(a)	a register of holders in which shall be entered in alphabetical order the names and addresses of
the holders of Warrants and particulars of the Warrants held by them and the Warrant Agent shall be entitled to rely on such register
in connection with the exchange, transfer or exercise of any Warrant(s) pursuant to the terms of this Indenture or the terms thereof;
and

 

		(b)	a register of transfers in which all transfers of Warrants and the date and other particulars of
each such transfer shall be entered.

 

(2)           No
transfer of any Warrant will be valid unless entered on the register of transfers referred to in subsection 2.8(1), and, in
the case of a Warrant Certificate, upon surrender to the Warrant Agent of the Warrant Certificate evidencing such Warrant, and
a duly completed and executed transfer form endorsed on the Warrant Certificate executed by the registered holder or his executors,
administrators or other legal representatives or his attorney duly appointed by an instrument in writing in form and execution
satisfactory to the Warrant Agent, if applicable, and, upon compliance with such requirements and such other reasonable requirements
as the Warrant Agent may prescribe, such transfer will be recorded on the register of transfers by the Warrant Agent.

 

(3)          In
the case of a Warrant Certificate, the transferee of any Warrant will, after surrender to the Warrant Agent of the Warrant Certificate
evidencing such Warrant as required by subsection 2.8(2) and upon compliance with all other conditions in respect thereof
required by this Indenture or by law, be entitled to be entered on the register of holders referred to in subsection 2.8(1)
as the owner of such Warrant free from all equities or rights of set-off or counterclaim between the Company and the transferor
or any previous holder of such Warrant, except in respect of equities or rights of which the Company is required to take notice
by statute or by order of a court of competent jurisdiction.

 

(4)          The
Company will be entitled, and may direct the Warrant Agent, to refuse to recognize any transfer, or enter the name of any transferee,
of any Warrant on the registers referred to in subsection 2.8(1), if such transfer would constitute a violation of (a) the
Securities Laws of any applicable jurisdiction or the rules, regulations or policies of any regulatory authority having jurisdiction,
(b) any restrictive legend on such Warrant or (c) any applicable representations and warranties made by the Warrantholder in a
QIB Letter executed by such Warrantholder in connection with the Offering. The Warrant Agent is entitled to assume compliance with
all applicable Securities Laws unless otherwise notified in writing by the Company. No duty shall rest with the Warrant Agent to
determine compliance of the transferee or transferor of any Warrant with applicable Securities Laws.

 

(5)            Warrants
held by a Warrantholder in the United States or a U.S. Person that is a Qualified Institutional Buyer shall not be offered,
sold or otherwise transferred except (A) to the Company or (B) outside the United States in accordance with Rule 904
of Regulation S and in compliance with applicable local securities laws and regulations, as provided for in the QIB Letter
for such Warrantholder.

 

    	 	- 11 -	 

     

    

 

		2.9	Registers Open for Inspection

 

The registers referred
to in subsection 2.8(1) shall be open at all reasonable times during business hours on a Business Day for inspection by the
Company or any Warrantholder. The Warrant Agent shall, from time to time when requested to do so in writing by the Company and
upon payment of its reasonable fees, furnish the Company with a list of the names and addresses of holders of Warrants entered
in the register of holders kept by the Warrant Agent and showing the number of Warrants held by each such holder.

 

		2.10	Exchange of Warrant Certificates

 

(1)           Warrant
Certificates may, upon compliance with the reasonable requirements of the Warrant Agent, be exchanged for Warrant Certificates
in any other authorized denomination representing in the aggregate an equal number of Warrants as the number of Warrants represented
by the Warrant Certificates being exchanged. The Company shall sign and the Warrant Agent shall certify, in accordance with sections 2.3
and 2.4, all Warrant Certificates necessary to carry out the exchanges contemplated herein.

 

(2)           Warrant
Certificates may be exchanged only at the principal stock transfer offices of the Warrant Agent in the City of Toronto, Ontario
or at any other place that is designated by the Company with the approval of the Warrant Agent. Any Warrant Certificates tendered
for exchange shall be surrendered to the Warrant Agent and cancelled.

 

(3)           Except
as otherwise herein provided, the Warrant Agent may charge Warrantholders requesting an exchange a reasonable sum for each Warrant
Certificate issued; and payment of such charges and reimbursement of the Warrant Agent or the Company for any and all taxes or
governmental or other charges required to be paid shall be made by the party requesting such exchange as a condition precedent
to such exchange.

 

		2.11	Ownership of Warrants

 

The Company and the Warrant
Agent and their respective agents may deem and treat the registered holder of any Warrant as the absolute owner of the Warrant
represented thereby for all purposes and the Company and the Warrant Agent and their respective agents shall not be affected by
any notice or knowledge to the contrary except as required by statute or order of a court of competent jurisdiction. The holder
of any Warrant shall be entitled to the rights evidenced by that Warrant free from all equities or rights of set-off or counterclaim
between the Company and the original or any intermediate holder thereof and all persons may act accordingly and the receipt by
any holder of the Warrant Shares or monies obtainable pursuant to the exercise of the Warrant shall be a good discharge to the
Company and the Warrant Agent for the same and neither the Company nor the Warrant Agent shall be bound to inquire into the title
of any holder.

 

    	 	- 12 -	 

     

    

 

		2.12	Book-Based System Warrants

 

(1)          Except
as described above, and except as may be directed by the Company, registration of interests in and transfers of Warrants shall
be made only through the Book-Based System. Other than as may be directed by the Company, the Warrants will be evidenced by a non-certificated
inventory (“NCI”) deposit though the Book-Based System for an amount representing the aggregate number of such
Warrants outstanding from time to time.

 

(2)           Transfers
of beneficial ownership in any Warrant represented by an NCI deposit will be effected only (i) with respect to the interest of
a CDS Participant, through records maintained by CDS or its nominee for such Warrants, and (ii) with respect to the interest of
any person other than a CDS Participant, through records maintained by CDS Participants.

 

(3)           The
rights of Beneficial Owners who hold security entitlements in respect of Warrants through the Book-Based System shall be limited
to those established by applicable law and agreements between CDS and CDS Participants and between such CDS Participants and Beneficial
Owners who hold security entitlements in respect of Warrants through the Book-Based System and must be exercised through a CDS
Participant in accordance with the rules and procedures of CDS.

 

(4)           If
any of the following events occurs:

 

		(a)	CDS or the Company has notified the Warrant Agent that (A) CDS is unwilling or unable to continue
as depository or (B) CDS ceases to be a clearing agency in good standing under applicable laws and, in either case, the Company
is unable to locate a qualified successor depository within 90 days of delivery of such notice;

 

		(b)	the Company has determined, in its sole discretion, to terminate the Book-Based System in respect
of such Uncertificated Warrants and has communicated such determination to the Warrant Agent in writing;

 

		(c)	the Company or CDS is required by applicable law to take the action contemplated in this subsection;
or

 

		(d)	the Book-Based System administered by CDS ceases to exist,

 

then one or more definitive fully registered
Warrant Certificates shall be executed by the Company and certified and delivered by the Warrant Agent to CDS in exchange for the
Uncertificated Warrants form held by CDS.

 

Fully registered Warrant
Certificates issued and exchanged pursuant to this subsection shall be registered in such names and in such denominations as CDS
shall instruct the Warrant Agent, provided that the aggregate number of Warrants represented by such Warrant Certificates shall
be equal to the aggregate number of Uncertificated Warrants so exchanged. Upon exchange of Uncertificated Warrants for one or more
Warrant Certificates in definitive form, such Uncertificated Warrants shall be cancelled by the Warrant Agent.

 

    	 	- 13 -	 

     

    

 

(5)           Notwithstanding
anything in this Indenture in terms of an NCI deposit, neither the Company nor the Warrant Agent nor any agent thereof shall have
any responsibility or liability for:

 

		(a)	the records maintained by CDS relating to any ownership interests or any other interests in the
Warrants or the depository system maintained by CDS, or payments made on account of any ownership interest or any other interest
of any person in any Warrant represented by any NCI deposit (other than CDS or its nominee);

 

		(b)	maintaining, supervising or reviewing any records of CDS or any CDS Participant relating to any
such interest; or

 

		(c)	any advice or representation made or given by CDS or those contained in this Indenture that relate
to the rules and regulations of CDS or any action to be taken by CDS on its own direction or at the direction of any CDS Participant.

 

		2.13	Adjustment of Exchange Basis

 

Subject to section 2.14,
the Exchange Basis shall be subject to adjustment from time to time in the events and in the manner provided as follows:

 

(1)           If
and whenever, at any time after the date hereof and prior to the Time of Expiry, the Company shall:

 

		(i)	issue Common Shares or securities exchangeable for or convertible into Common Shares to all or
substantially all the holders of the Common Shares as a stock dividend or other distribution (other than a distribution of Warrant
Shares upon exercise of the Warrants or pursuant to the exercise, conversion or exchange of securities of the Company outstanding
as of the date hereof), or

 

		(ii)	subdivide, redivide or change its then outstanding Common Shares into a greater number of Common
Shares, or

 

		(iii)	reduce, combine or consolidate its then outstanding Common Shares into a lesser number of Common
Shares,

 

(any of such events in these paragraphs (i),
(ii) or (iii) being called a “Common Share Reorganization”), then the Exchange Basis in effect on the effective
date of such subdivision, redivision or change, or reduction, combination or consolidation, or on the record date of such stock
dividend or other distribution, as the case may be, shall be adjusted by multiplying the Exchange Basis in effect immediately prior
to such effective or record date by a fraction:

 

		(a)	the numerator of which shall be the total number of Common Shares outstanding on such date immediately
after giving effect to such Common Share Reorganization (including, in the case where securities exercisable, exchangeable for
or convertible into Common Shares are distributed, the number of Common Shares that would have been outstanding had such securities
been exercised, or exchanged for or converted into Common Shares on such record date, assuming in any case where such securities
are not then convertible, exercisable or exchangeable but subsequently become so, that they were convertible, exercisable or exchangeable
on the record date on the basis upon which they first become convertible, exercisable or exchangeable), and

 

    	 	- 14 -	 

     

    

 

		(b)	the denominator of which shall be the total number of Common Shares outstanding on such date before
giving effect to such Common Share Reorganization.

 

The resulting
product, adjusted to the nearest 1/100th, shall thereafter be the Exchange Basis until further adjusted as provided in this Article 2.

 

Any Common Shares owned by or
held for the account of the Company or any of its Subsidiaries or a partnership in which the Company is directly or indirectly
a party to will be deemed not to be outstanding for the purpose of any computation. To the extent that any adjustment in the Exchange
Basis occurs pursuant to this subsection 2.13(1) as a result of the fixing by the Company of a record date for the distribution
of securities exchangeable or exercisable for or convertible into Common Shares and the Common Share Reorganization does not occur
or any conversion, exercise or exchange rights are not fully converted, exercised or exchanged, the Exchange Basis shall be readjusted
immediately after the expiry of any relevant exchange or conversion right or the termination of the Common Share Reorganization,
as the case may be, to the Exchange Basis that would then be in effect, based upon the number of Common Shares actually issued
and remaining issuable after such expiry and shall be further readjusted in such manner upon the expiry of any further such right.

 

(2)           If
and whenever, at any time after the date hereof and prior to the Time of Expiry, the Company shall fix a record date for the distribution
to all or substantially all of the holders of its outstanding Common Shares of rights, options or warrants entitling them, for
a period expiring not less than 21 days and not more than 90 days after such record date, to subscribe for or purchase Common
Shares, or securities exchangeable or exercisable for or convertible into Common Shares, at a price per share to the holder (or
at an exchange, exercise or conversion price per share) of less than 95% of the Current Market Price on such record date (any of
such events being called a “Rights Offering”), then the Exchange Basis shall be adjusted effective immediately
after such record date for the Rights Offering by multiplying the Exchange Basis in effect immediately prior to such record date
by a fraction:

 

		(a)	the numerator of which shall be the number of Common Shares which would be outstanding after giving
effect to the Rights Offering (assuming the exercise of all of the rights, options or warrants under the Rights Offering and assuming
the exchange, exercise or conversion into Common Shares of all exchangeable, exercisable or convertible securities issued upon
exercise of such rights, options or warrants, if any), and

 

    	 	- 15 -	 

     

    

 

		(b)	the denominator of which shall be the aggregate of:

 

		(i)	the total number of Common Shares outstanding as of the record date for the Rights Offering, and

 

		(ii)	a number of Common Shares determined by dividing

 

		(A)	the amount equal to the aggregate consideration payable on the exercise of all of the rights, options
and warrants under the Rights Offering plus the aggregate consideration, if any, payable on the exchange, exercise or conversion
of the exchangeable or convertible securities issued upon exercise of such rights, options or warrants (assuming the exercise of
all rights, options and warrants under the Rights Offering and assuming the exchange or conversion of all exchangeable or convertible
securities issued upon exercise of such rights, options and warrants);

 

by

 

		(B)	the Current Market Price as of the record date for the Rights Offering.

 

The resulting product, adjusted to the
nearest 1/100th, shall thereafter be the Exchange Basis until further adjusted as provided in this Article 2. Any Common Shares
owned by or held for the account of the Company or any of its Subsidiaries or a partnership in which the Company is directly or
indirectly a party to will be deemed not to be outstanding for the purpose of any computation. If, at the date of expiry of the
rights, options or warrants subject to the Rights Offering, less than all the rights, options or warrants have been exercised,
then the Exchange Basis shall be readjusted effective immediately after the date of expiry to the Exchange Basis which would have
been in effect on the date of expiry if only the rights, options or warrants issued had been those exercised. If at the date of
expiry of the rights of exchange, exercise or conversion of any securities issued pursuant to the Rights Offering less than all
of such securities have been exchanged or exercised for, or converted into, Common Shares, then the Exchange Basis shall be readjusted
effective immediately after the date of expiry to the Exchange Basis which would have been in effect on the date of expiry if only
the exchangeable, exercisable or convertible securities issued had been those securities actually exchanged or exercised for or
converted into Common Shares.

 

(3)           If
and whenever, at any time after the date hereof and prior to the Time of Expiry, the Company shall fix a record date for the issuance
or distribution to all or substantially all the holders of its outstanding Common Shares of:

 

		(i)	shares of the Company of any class other than Common Shares; or

 

		(ii)	rights, options or warrants to acquire Common Shares or securities exchangeable or exercisable
for or convertible into Common Shares; or

 

		(iii)	evidences of indebtedness; or

 

    	 	- 16 -	 

     

    

 

		(iv)	cash, securities or any property or other assets,

 

and if such issuance or distribution does
not constitute a Common Share Reorganization or a Rights Offering (any of such non-excluded events being herein called a “Special
Distribution”), the Exchange Basis shall be adjusted effective immediately after the record date for the Special Distribution
by multiplying the Exchange Basis in effect on such record date by a fraction:

 

		(a)	the numerator of which shall be the number of Common Shares outstanding on such record date multiplied
by the Current Market Price on such record date, and

 

		(b)	the denominator of which shall be:

 

		(A)	the product of the number of Common Shares outstanding on such record date and the Current Market
Price on such record date,

 

less

 

		(B)	the fair market value, as determined by action by the board of directors acting reasonably and
in good faith (whose determination shall, absent manifest error, be conclusive), to the holders of the Common Shares of the shares,
rights, options, warrants, evidences of indebtedness or property or other assets issued or distributed in the Special Distribution,

 

provided that no such adjustment shall
be made if the result of such adjustment would be to decrease the Exchange Basis in effect immediately before such record date.
The resulting product, adjusted to the nearest 1/100th, shall thereafter be the Exchange Basis until further adjusted as provided
in this Article 2. Any shares owned by or held for the account of the Company or its Subsidiaries or a partnership of which
the Company is directly or indirectly a party to shall be deemed not to be outstanding for the purpose of any such computation.

 

(4)           If
and whenever, at any time after the date hereof and prior to the Time of Expiry, there shall be a reclassification of the Common
Shares at any time outstanding or change or exchange of the Common Shares into other shares or into other securities (other than
a Common Share Reorganization), or a consolidation, amalgamation, plan of arrangement or merger of the Company with or into any
other corporation or other entity (other than a consolidation, amalgamation, plan of arrangement 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 a transfer (other
than to a Subsidiary) of the undertaking or assets of the Company as an entirety or substantially as an entirety to another corporation
or other entity (any of such events being herein called a “Capital Reorganization”), any Warrantholder who thereafter
shall exercise his right to receive Warrant Shares pursuant to Warrant(s) shall be entitled to receive, and shall accept in lieu
of the number of Warrant Shares to which such holder was theretofore entitled upon such exercise, the aggregate number of shares,
other securities or other property resulting from the Capital Reorganization which such holder would 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 Warrantholder
had been the registered holder of the number of Warrant Shares to which such holder was theretofore entitled upon exercise. If
appropriate, adjustments shall be made as a result of any such Capital Reorganization in the application of the provisions set
forth in this Article 2 with respect to the rights and interests thereafter of Warrantholders to the end that the provisions
set forth in this Article 2 shall thereafter correspondingly be made applicable as nearly as may reasonably be in relation
to any shares, other securities or other property thereafter deliverable upon the exercise of any Warrant. Any such adjustment
shall be made by and set forth in an indenture supplemental hereto approved by the directors and by the Warrant Agent and entered
into pursuant to the provisions of this Indenture and shall for all purposes be conclusively deemed to be an appropriate adjustment.

 

    	 	- 17 -	 

     

    

  

(5)           Any
adjustment to the Exchange Basis as set forth herein (except resulting from a Capital Reorganization) shall also include a corresponding
adjustment to the Exercise Price which shall be calculated by multiplying the Exercise Price by a fraction: (a) the numerator of
which shall be the Exchange Basis prior to the adjustment, and (b) the denominator of which shall be the Exchange Basis after the
adjustment.

 

		2.14	Rules Regarding Calculation of Adjustment of Exchange Basis

 

For the purposes of section 2.13:

 

(1)           The
adjustments provided for in section 2.13 shall be cumulative and such adjustments shall be made successively whenever an event
referred to in section 2.13 shall occur, subject to the following subsections of this section 2.14.

 

(2)           No
adjustment in the: (a) Exchange Basis shall be required unless such adjustment would result in a change of at least 0.01 of
a Warrant Share based on the prevailing Exchange Basis; or (b) Exercise Price shall be required unless such adjustment would
result in a change of at least 1%, provided that any adjustments which, except for the provisions of this subsection, would otherwise
have been required to be made, shall be carried forward and taken into account in any subsequent adjustment.

 

(3)           No
adjustment in the Exchange Basis shall be made in respect of any event described in section 2.13, other than the events referred
to in paragraphs (ii) and (iii) of subsection (1) thereof, if Warrantholders are entitled to participate in such
event on the same terms, mutatis mutandis, as if Warrantholders had exercised their Warrants prior to or on the effective date
or record date of such event, any such participation being subject to regulatory approval.

 

(4)           No
adjustment in the Exchange Basis shall be made pursuant to section 2.13 in respect of the issue from time to time of Warrant
Shares purchasable on exercise of the Warrants or pursuant to the exercise, conversion or exchange of securities of the Company
outstanding as of the date hereof.

 

(5)           If
a dispute shall at any time arise with respect to adjustments provided for in section 2.13, such dispute shall, absent manifest
error, be conclusively determined by the Company’s Auditors, or if they are unable or unwilling to act, by such other firm
of independent chartered accountants as may be selected by the directors and any further determination, absent manifest error,
shall be binding upon the Company, the Warrant Agent and the Warrantholders.

 

    	 	- 18 -	 

     

    

 

(6)            If
the Company shall set a record date to determine the holders of the Common Shares for the purpose of entitling them to receive
any dividend or distribution or any subscription or purchase rights and shall, thereafter and before the distribution to such shareholders
of any such dividend, distribution, or subscription or purchase rights, legally abandon its plan to pay or deliver such dividend,
distribution, or subscription or purchase rights, then no adjustment in the Exchange Basis shall be required by reason of the setting
of such record date.

 

(7)            In
the absence of a resolution of the directors fixing a record date for a Rights Offering or Special Distribution, the Company shall
be deemed to have fixed as the record date therefor the date on which the Rights Offering or Special Distribution is effected.

 

(8)           If
the purchase price provided for in any Rights Offering (the “Rights Offering Price”) is decreased, the Exchange
Basis shall forthwith be changed so as to increase the Exchange Basis to such Exchange Basis as would have been obtained had the
adjustment to the Exchange Basis made pursuant to subsection 2.13(2) upon the issuance of such Rights Offering been made upon
the basis of the Rights Offering Price as so decreased, provided that the provisions of this subsection shall not apply to any
decrease in the Rights Offering Price resulting from provisions in any such Rights Offering designed to prevent dilution if the
event giving rise to such decrease in the Rights Offering Price itself requires an adjustment to the Exchange Basis pursuant to
the provisions of section 2.13.

 

(9)           As
a condition precedent to the taking of any action that would require any adjustment in any of the subscription rights pursuant
to any of the Warrants, including the Exchange Basis, the Company shall take any corporate action which may, in the opinion of
counsel, be necessary in order that the Company have unissued and reserved in its authorized capital and may validly and legally
issue as fully paid and non-assessable all the shares or other securities that all the holders of such Warrants are entitled to
receive on the exercise of all the subscription rights attaching thereto in accordance with the provisions thereof.

 

(10)         The
Warrant Agent shall be entitled to act and rely on any adjustment calculations by the Company or the Company’s Auditors.

 

		2.15	Postponement of Subscription

 

In any case where the
application of section 2.13 results in an increase in the number of Common Shares that are issuable upon exercise of the Warrants
taking effect immediately after the record date for a specific event, if any Warrant is exercised after that record date and prior
to completion of such specific event, the Company may postpone the issuance to the Warrantholder of the Warrant Shares to which
he is entitled by reason of such adjustment, but such Warrant Shares shall be so issued and delivered to that holder upon completion
of that event, with the number of such Warrant Shares calculated on the basis of the number of Warrant Shares on the date that
the Warrant was exercised, adjusted for completion of that event and the Company shall deliver to the person or persons in whose
name or names the Warrant Shares are to be issued an appropriate instrument evidencing the right of such person or persons to receive
such Warrant Shares and the right to receive any dividends or other distributions which, but for the provisions of this section 2.15,
such person or persons would have been entitled to receive in respect of such Warrant Shares from and after the date that the Warrant
was exercised in respect thereof.

		2.16	Notice of Adjustment

 

(1)           At
least 14 days prior to the effective date or record date, as the case may be, of any event which requires or might require
adjustment pursuant to section 2.13, the Company shall:

 

		(a)	file with the Warrant Agent a certificate of the Company specifying the particulars of such event
(including the record date or the effective date for such event) and, if determinable, the required adjustment and the computation
of such adjustment; and

 

		(b)	give notice to the Warrant Agent and the Warrantholders of the particulars of such event (including
the record date or the effective date for such event) and, if determinable, the required adjustment.

 

(2)           In
case any adjustment for which a notice in subsection 2.16(1) has been given is not then determinable, the Company shall promptly
after such adjustment is determinable:

 

		(a)	file with the Warrant Agent a computation of such adjustment; and

 

		(b)	give notice to the Warrantholders of the adjustment.

 

(3)           The
Warrant Agent may, absent manifest error, act and rely upon certificates and other documents filed by the Company pursuant to this
section 2.16 for all purposes of the adjustment.

 

		2.17	No Action after Notice

 

The Company covenants
with the Warrant Agent that it will not take any other corporate action which might deprive a Warrantholder of the opportunity
of exercising the rights of acquisition pursuant thereto during the period of 10 days after the giving of the notice set forth
in subsection 2.16(1) and paragraph (b) of subsection 2.16(2).

 

		2.18	Optional Purchases by the Company

 

Subject to applicable
law and prior approval of the TSXV, if required, the Company may from time to time purchase on any stock exchange (if then listed),
in the open market, by private agreement or otherwise any of the Warrants. Any such purchase shall be made at the lowest price
or prices at which, in the opinion of the board of directors of the Company, such Warrants are then obtainable, plus reasonable
costs of purchase, and may be made in such manner, from such persons, and on such other terms as the Company in its sole discretion
may determine. The Warrant Certificates representing the Warrants purchased pursuant to this section 2.18 shall forthwith
be delivered to and cancelled by the Warrant Agent.

		2.19	Protection of Warrant Agent

 

Subject to Article 8,
the Warrant Agent shall not:

 

		(a)	at any time be under any duty or responsibility to any registered holder of Warrants to determine
whether any facts exist that may require any adjustment contemplated by this Article 2, nor to verify the nature and extent
of any such adjustment when made or the method employed in making the same;

 

		(b)	be accountable with respect to the validity or value or the kind or amount of any Warrant Shares
that may at any time be issued or delivered upon the exercise of the Warrants;

 

		(c)	be responsible for any failure of the Company to make any cash payment upon the surrender of any
Warrants for the purpose of the exercise of such rights or to comply with any of the covenants contained in this Article 2;
or

of any breach on the part of the Company of any of the representations, warranties or covenants of the Company or any acts or deeds
of the agents or servants of the Company.

 

		2.20	U.S. Securities Law Matters

 

The Warrant Agent understands
and acknowledges that the Warrants and the Warrant Shares issuable upon exercise of the Warrants have not been, and will not be,
registered under the U.S. Securities Act or the securities laws of any state of the United States. The Warrant Agent
further understands and acknowledges that Warrants originally issued in the United States or, to, or for the account or benefit
of, a person in the United States or U.S. Persons, will be issued only to Qualified Institutional Buyers, each of whom will be
required to sign a QIB Letter prior to such issuance. In accordance with the terms of each such QIB Letter, such Warrants issued
to Qualified Institutional Buyers shall be issued in uncertificated form and deposited in CDS in accordance with this Section 2,
and shall not bear a legend relating to transfer restrictions under the U.S. Securities Act.

 

Article 3

EXERCISE OF WARRANTS

 

		3.1	Method of Exercise of Warrants

 

(1)          The
registered holder of any Warrant may exercise the rights thereby conferred on him to acquire all or any part of the Warrant Shares
to which such Warrant entitles the holder, by surrendering the Warrant Certificate representing such Warrants to the Warrant Agent
at any time prior to the Time of Expiry at its principal stock transfer offices in the City of Toronto, Ontario (or at such additional
place or places as may be decided by the Company from time to time with the approval of the Warrant Agent), with a duly completed
and executed exercise form of the registered holder or his executors, administrators or other legal representative or his attorney
duly appointed by an instrument in writing in the form and manner satisfactory to the Warrant Agent, substantially in the form
endorsed on the Warrant Certificate specifying the number of Warrant Shares subscribed for together with a certified cheque, bank
draft or money order in lawful money of Canada, payable to or to the order of the Company in an amount equal to the Exercise Price
multiplied by the number of Warrant Shares subscribed for. A Warrant Certificate with the duly completed and executed exercise
form and payment of the Exercise Price shall be deemed to be surrendered only upon personal delivery thereof to or, if sent by
mail or other means of transmission, upon actual receipt thereof by the Warrant Agent.

 

    	 	- 21 -	 

     

    

 

(2)           Any
exercise form referred to in subsection 3.1(1) shall be signed by the Warrantholder, or his executors, or administrators or
other legal representative or his attorney duly appointed by an instrument in writing in the form and manner satisfactory to the
Warrant Agent, shall specify the person(s) in whose name such Warrant Shares are to be issued, the address(es) of such person(s)
and the number of Warrant Shares to be issued to each person, if more than one is so specified. If any of the Warrant Shares subscribed
for are to be issued to (a) person(s) other than the Warrantholder, the signatures set out in the exercise form referred to
in subsection 3.1(1) shall be guaranteed by a Canadian Schedule I chartered bank or a medallion signature guarantee from
a member of a recognized Signature Medallion Guarantee Program and (b) the Warrantholder shall pay to the Company or the Warrant
Agent all applicable transfer or similar taxes and the Company shall not be required to issue or deliver certificates evidencing
Warrant Shares unless or until such Warrantholder shall have paid to the Company or the Warrant Agent on behalf of the Company
the amount of such tax or shall have established to the reasonable satisfaction of the Company that such tax has been paid or that
no tax is due.

 

(3)           If,
at the time of exercise of the Warrants, in accordance with the provisions of subsection 3.1(1), there are any trading restrictions
on the Warrant Shares pursuant to Securities Laws or stock exchange requirements, the Company shall, on the advice of counsel,
endorse any certificates representing the Warrant Shares to such effect. The Warrant Agent is entitled to assume compliance with
all Securities Laws unless otherwise notified in writing by the Company.

 

(4)           A
Beneficial Owner who desires to exercise his Uncertificated Warrants, must do so by causing a CDS Participant to deliver to CDS
(at its office in the City of Toronto), on behalf of the Beneficial Owner at any time prior to the Time of Expiry, a written notice
of the Beneficial Owner’s intention to exercise Warrants (the “Exercise Notice”). Forthwith upon receipt
by CDS of such notice, as well as payment for the Exercise Price, CDS shall deliver to the Warrant Agent confirmation of its intention
to exercise Warrants (the “Confirmation”) in a manner acceptable to the Warrant Agent, including by electronic
means through the Book-Based System. CDS will initiate the exercise by way of the Confirmation and forward the aggregate Exercise
Price electronically to the Warrant Agent and the Warrant Agent will execute the exercise by causing the issuance to CDS through
the Book-Based System of the Warrant Shares to which the exercising Beneficial Owner is entitled pursuant to the exercise. Any
expense associated with the preparation and delivery of Exercise Notices will be for the account of the Beneficial Owner exercising
the Warrants.

 

By causing a CDS Participant
to deliver notice to CDS, a Beneficial Owner shall be deemed to have irrevocably surrendered his Warrants so exercised and appointed
such CDS Participant to act as his or her exclusive settlement agent with respect to the exercise and the receipt of Warrant Shares
in connection with the obligations arising from such exercise.

 

    	 	- 22 -	 

     

    

 

Any notice which CDS
determines to be incomplete, not in proper form or not duly executed shall for all purposes be void and of no effect and the exercise
to which it relates shall be considered for all purposes not to have been exercised thereby. A failure by a CDS Participant to
exercise or to give effect to the settlement thereof in accordance with the Beneficial Owner’s instructions will not give
rise to any obligations or liability on the part of the Company or Warrant Agent to the CDS Participant or the Beneficial Owner.

 

		3.2	No Fractional Warrant Shares

 

Under no circumstances
shall the Company be obliged to issue any fractional Warrant Shares or any cash or other consideration in lieu thereof upon the
exercise of one or more Warrants. To the extent that the holder of one or more Warrants would otherwise have been entitled to receive
on the exercise or partial exercise thereof a fraction of a Warrant Share, that holder may exercise that right in respect of the
fraction only in combination with another Warrant or Warrants that in the aggregate entitle the holder to purchase a whole number
of Warrant Shares; otherwise fractional Warrant Shares shall be rounded down to the nearest whole number of Warrant Shares without
compensation therefor.

 

		3.3	Effect of Exercise of Warrants

 

(1)           Upon
compliance by the Warrantholder with the provisions of section 3.1, the Warrant Shares subscribed for shall be deemed to have
been issued and the person to whom such Warrant Shares are to be issued shall be deemed to have become the holder of record of
such Warrant Shares on the Exercise Date unless the transfer registers of the Company for the Common Shares shall be closed on
such date, in which case the Warrant Shares subscribed for shall be deemed to have been issued and such person shall be deemed
to have become the holder of record of such Warrant Shares on the date on which such transfer registers are reopened.

 

(2)            Within
three Business Days following the due exercise of a Warrant pursuant to section 3.1, and if requested by the Company forthwith
after the Time of Expiry, the Warrant Agent shall deliver to the Company a notice setting forth the particulars of all Warrants
exercised, if any, and the persons in whose names the Warrant Shares are to be issued (as applicable) and the addresses of such
holders of the Warrant Shares.

 

(3)           Within
three Business Days of the due exercise of a Warrant pursuant to section 3.1, the Company shall cause the Transfer Agent to
issue, within such three Business Day period, to CDS through the Book-Based System the Warrant Shares (which shall include Warrant
Shares issued to a Purchaser that is a Qualified Institutional Buyer) to which the exercising Warrantholder is entitled pursuant
to the exercise or mail to the person in whose name the Warrant Shares so subscribed for are to be issued, as specified in the
exercise form completed on the Warrant Certificate, at the address specified in such exercise form, a certificate or certificates
for the Warrant Shares to which the Warrantholder is entitled and, if applicable, shall cause the Warrant Agent to mail a Warrant
Certificate representing any Warrants not then exercised.

 

    	 	- 23 -	 

     

    

   

		3.4	Cancellation of Warrants

 

All Warrants surrendered
to the Warrant Agent pursuant to sections 2.6, 2.8(2), 2.10, 2.18 or 3.1 shall be cancelled by the Warrant Agent and
the Warrant Agent shall record the cancellation of such Warrants on the register of holders maintained by the Warrant Agent pursuant
to subsection 2.8(1). The Warrant Agent shall, if required by the Company, furnish the Company with a certificate identifying
the Warrants so cancelled. All Warrants that have been duly cancelled shall be without further force or effect whatsoever.

 

		3.5	Subscription for less than Entitlement

 

The holder of any Warrant
may subscribe for and purchase a whole number of Warrant Shares that is less than the number that the holder is entitled to purchase
pursuant to a surrendered Warrant. In such event, the holder thereof shall be entitled to receive a new Warrant Certificate, if
applicable, in respect of the balance of Warrants that were not then exercised.

 

		3.6	Expiration of Warrant

 

After the Time of Expiry,
all rights under any Warrant in respect of which the right of subscription and purchase herein and therein provided for shall not
theretofore have been exercised shall wholly cease and terminate and such Warrant shall be void and of no effect.

 

		3.7	Exercise by U.S. Persons

 

The Warrant Agent understands
and acknowledges that the Warrants may not be exercised within the United States or by or on behalf of, or for the account or benefit
of, any U.S. Person or any person in the United States except pursuant to an available exemption under the Securities Act
and applicable U.S. state securities laws. The Warrant Agent further understands and acknowledges that Warrantholders that have
executed and delivered a QIB Letter are required to be a Qualified Institutional Buyer and/or an Accredited Investor in connection
with the exercise of Warrants by such Warrantholders.

 

    	 	- 24 -	 

     

    

   

		3.8	Limitation on Exercise

 

Neither the Company nor
the Warrant Agent shall effect any exercise of a Warrant, and a Warrantholder shall not have the right to exercise any portion
of a Warrant, pursuant to this Article 3 or otherwise, to the extent that, after giving effect to such issuance after exercise
as set forth on the applicable exercise form, the Warrantholder (together with the Warrantholder’s affiliates, and any other
persons acting as a group together with the Warrantholder or any of the Warrantholder’s affiliates (such persons, “Attribution
Parties”)), would beneficially own, or exercise control or direction over, in excess of the Beneficial Ownership Limitation
(as defined below). For purposes of the foregoing sentence, the number of Common Shares beneficially owned by the Warrantholder
and its affiliates and Attribution Parties shall include the number of Common Shares issuable upon exercise of a Warrant with respect
to which such determination is being made, but shall exclude the number of Common Shares that would be issuable upon (i) exercise
of the remaining, non-exercised portion of a Warrant beneficially owned by the Warrantholder or any of its affiliates or Attribution
Parties, and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company (including,
without limitation, any other Common Share Equivalents), subject to a limitation on conversion or exercise analogous to the limitation
contained herein, beneficially owned by the Warrantholder or any of its affiliates or Attribution Parties. Except as set forth
in the preceding sentence, for purposes of this section 3.8, beneficial ownership shall be calculated in accordance with Section
13(d) of the U.S. Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the Warrantholder
that neither the Warrant Agent nor the Company is representing to the Warrantholder that such calculation is in compliance with
Section 13(d) of the U.S. Exchange Act and the Warrantholder further acknowledges that it is solely responsible for any schedules
required to be filed in accordance therewith. To the extent that the limitation contained in this Section 3.8 applies, the determination
of whether a Warrant is exercisable (in relation to other securities owned by the Warrantholder together with any affiliates and
Attribution Parties) and of which portion of a Warrant is exercisable shall be in the sole discretion and at the sole responsibility
of the Warrantholder, and the submission of an exercise form shall be deemed to be the Warrantholder’s determination of whether
a Warrant is exercisable (in relation to other securities owned by the Warrantholder together with any affiliates and Attribution
Parties) and of which portion of a Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and neither
the Warrant Agent nor the Company shall have any obligation to verify or confirm the accuracy of such determination. In addition,
a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the U. S.
Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 3.8 in determining the number of
outstanding Common Shares, a Warrantholder may rely on the number of outstanding Common Shares as reflected in (A) the Company’s
most recent periodic or annual report filed on SEDAR, (B) a more recent public announcement by the Company, or (C) a more recent
written notice by the Company or the Company’s transfer agent setting forth the number of Common Shares outstanding. Upon
the written or oral request of a Warrantholder, the Company shall, within two trading days, confirm orally and in writing to the
Warrantholder the number of Common Shares then outstanding. In any case, the number of outstanding Common Shares shall be determined
after giving effect to the conversion or exercise of securities of the Company, including the Warrant being exercised, by the Warrantholder
or its affiliates or Attribution Parties since the date as of which such number of outstanding Common Shares was reported. The
 “Beneficial Ownership Limitation” shall be 9.99% of the number of Common Shares outstanding immediately after
giving effect to the issuance of Warrant Shares issuable upon exercise of the Warrant in question. The provisions of this paragraph
shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 3.8 to correct
this paragraph (or any portion hereof) that may be defective or inconsistent with the intended Beneficial Ownership Limitation
herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations
contained in this Section 3.8 shall apply to a successor holder of a Warrant. For greater certainty, the Warrant Agent will have
no responsibility for monitoring the beneficial ownership level of the Common Shares held by Warrantholders or their Attribution
Parties and will have no liability in regards to the determinations made of whether or not a Warrantholder or their Attribution
Parties would become a beneficial holder in excess of the Beneficial Ownership Limitation of the issued and outstanding Common
Shares upon exercise of their Warrants.

of preventing the Warrantholders from receiving any of the Warrant Shares issuable upon exercise of the Warrants.

(1)            If,
in the opinion of counsel, any instrument is required to be filed with, or any permission, order or ruling is required to be obtained
from, any securities regulatory authority or any other step is required under any federal or provincial law of Canada before the
Warrant Shares may be issued or delivered to a Warrantholder, the Company covenants that it will use its best efforts to file such
instrument, obtain such permission, order or ruling or take all such other actions, at its expense, as is required or appropriate

notice from the Warrant Agent of such failure, the Warrant Agent may notify the Warrantholders of such failure on the part of the

such notice or perform said covenants. All reasonable sums expended or disbursed by the Warrant Agent in so doing shall be repayable
as provided in section 4.3. No such performance, expenditure or advance by the Warrant Agent shall be deemed to relieve the
Company of any default hereunder or of its continuing obligations under the covenants herein contained.

Subject to section 6.10,
all or any of the rights conferred upon a Warrantholder by the terms of the Warrants held by him and/or this Indenture may be enforced

MEETINGS OF WARRANTHOLDERS

 

		6.1	Right to Convene Meetings

 

The Warrant Agent may
at any time and from time to time, and shall on receipt of a written request of the Company or of a Warrantholders’ Request,
convene a meeting of the Warrantholders provided that the Warrant Agent has been provided with sufficient funds and is indemnified
to its reasonable satisfaction by the Company or by the Warrantholders signing such Warrantholders’ Request against the costs,
charges, expenses and liabilities that may be incurred in connection with the calling and holding of such meeting. If within 15 Business
Days after the receipt of a written request of the Company or a Warrantholders’ Request, funding and indemnity given as aforesaid
the Warrant Agent fails to give the requisite notice specified in section 6.2 to convene a meeting, the Company or such Warrantholders,

place as may be approved or determined by the Warrant Agent.

 

		6.2	Notice

 

At least 14 days’
prior notice of any meeting of Warrantholders shall be given to the Warrantholders at the expense of the Company in the manner
provided for in section 9.2 and a copy of such notice shall be delivered to the Warrant Agent unless the meeting has been

the meeting, the general nature of the business to be transacted and shall contain such information as is reasonably necessary
to enable the Warrantholders to make a reasoned decision on the matter, but it shall not be necessary for any such notice to set
out the terms of any resolution to be proposed or any of the provisions of this Article 6. The notice convening any such meeting
may be signed by an appropriate officer of the Warrant Agent or of the Company or the person designated by such Warrantholders,
as the case may be.

 

    	 	- 28 -	 

     

    

   

		6.3	Chairman

 

The Warrant Agent may
nominate in writing an individual (who need not be a Warrantholder) to be chairman of the meeting and if no individual is so nominated,
or if the individual so nominated is not present within 15 minutes after the time fixed for the holding of the meeting, the
Warrantholders present in person or by proxy shall appoint an individual present to be chairman of the meeting. The chairman of
the meeting need not be a Warrantholder.

 

		6.4	Quorum

 

Subject to the provisions
of section 6.11, at any meeting of the Warrantholders a quorum shall consist of two Warrantholders present in person or represented
by proxy and representing at least 20% of the aggregate number of Warrants then outstanding. If a quorum of the Warrantholders
shall not be present within one-half hour from the time fixed for holding any meeting, the meeting, if summoned by the Warrantholders
or on a Warrantholders’ Request, shall be dissolved; but in any other case the meeting shall be adjourned to the same day
in the next week (unless such day is not a Business Day in which case it shall be adjourned to the next following Business Day)
at the same time and place to the extent possible and, subject to the provisions of section 6.11, no notice of the adjournment
need be given. Any business may be brought before or dealt with at an adjourned meeting that might have been dealt with at the
original meeting in accordance with the notice calling the same. At the adjourned meeting the Warrantholders present in person
or represented by proxy shall form a quorum and may transact the business for which the meeting was originally convened, notwithstanding
that they may not represent at least 20% of the aggregate number of Warrants then unexercised and outstanding. No business shall
be transacted at any meeting, except an adjourned meeting as described above, unless a quorum is present at the commencement of
business.

 

		6.5	Power to Adjourn

 

The chairman of any meeting
at which a quorum of the Warrantholders is present may, with the consent of the meeting, adjourn any such meeting, and no notice
of such adjournment need be given except such notice, if any, as the meeting may prescribe.

 

		6.6	Show of Hands

 

Every question submitted
to a meeting shall be decided in the first place by a majority of the votes given on a show of hands except that votes on an extraordinary
resolution shall be given in the manner hereinafter provided. At any such meeting, unless a poll is duly demanded as herein provided,
a declaration by the chairman that a resolution has been carried or carried unanimously or by a particular majority or lost or
not carried by a particular majority shall be conclusive evidence of the fact.

 

    	 	- 29 -	 

     

    

   

		6.7	Poll and Voting

 

On every extraordinary
resolution, and when demanded by the chairman or by one or more of the Warrantholders acting in person or by proxy on any other
question submitted to a meeting and after a vote by show of hands, a poll shall be taken in such manner as the chairman shall direct.
Questions other than those required to be determined by extraordinary resolution shall be decided by a majority of the votes cast
on the poll. On a show of hands, every person who is present and entitled to vote, whether as a Warrantholder or as proxy for one
or more absent Warrantholders, or both, shall have one vote. On a poll, each Warrantholder present in person or represented by
a proxy duly appointed by instrument in writing shall be entitled to one vote in respect of each whole Warrant then held by him.
A proxy need not be a Warrantholder. The chairman of any meeting shall be entitled, both on a show of hands and on a poll, to vote
in respect of the Warrants, if any, held or represented by him.

 

		6.8	Regulations

 

Subject to the provisions
of this Indenture, the Warrant Agent or the Company with the approval of the Warrant Agent may from time to time make and from
time to time vary such regulations as it shall consider necessary or appropriate:

 

		(a)	for the deposit of instruments appointing proxies at such place and time as the Warrant Agent,
the Company or the Warrantholders convening the meeting, as the case may be, may in the notice convening the meeting direct;

 

		(b)	for the deposit of instruments appointing proxies at some approved place other than the place at
which the meeting is to be held and enabling particulars of such instruments appointing proxies to be mailed or forwarded via facsimile
before the meeting to the Company or to the Warrant Agent at the place where the same is to be held and for the voting of proxies
so deposited as though the instruments themselves were produced at the meeting;

 

		(c)	for the form of instrument appointing a proxy and the manner in which the form of proxy may be
executed; and

 

		(d)	generally for the calling of meetings of Warrantholders and the conduct of business thereat including
setting a record date for Warrantholders entitled to receive notice of or to vote at such meeting.

 

Any regulations so made
shall be binding and effective and the votes given in accordance therewith shall be valid and shall be counted. Save as such regulations
may provide, the only persons who shall be recognized at any meeting as a Warrantholder, or be entitled to vote or be present at
the meeting in respect thereof (subject to section 6.9), shall be Warrantholders or persons holding proxies of Warrantholders.

 

		6.9	Company, Warrant Agent and Counsel may be Represented

 

The Company, the Warrantholders
and the Warrant Agent, by their respective directors, officers and employees and the counsel for each of the Company, the Warrantholders
and the Warrant Agent may attend any meeting of the Warrantholders and speak thereat but shall not be entitled to vote unless in

		6.10	Powers Exercisable by Extraordinary Resolution

 

In addition to all other
powers conferred upon them by any other provisions of this Indenture or by law, the Warrantholders at a meeting shall have the
power, exercisable from time to time by extraordinary resolution:

 

		(a)	to agree to any modification, alteration, compromise or arrangement of the rights of Warrantholders
and/or the Warrant Agent in its capacity as warrant agent hereunder (subject to the Warrant Agent’s approval) or on behalf
of the Warrantholders against the Company, whether such rights arise under this Indenture or the Warrants or otherwise;

 

		(b)	to amend, modify or repeal any extraordinary resolution previously passed or sanctioned by the
Warrantholders;

 

		(c)	to direct or authorize the Warrant Agent (subject to the Warrant Agent receiving funding and indemnity
to its satisfaction) to enforce any of the covenants on the part of the Company contained in this Indenture or the Warrants or
to enforce any of the rights of the Warrantholders in any manner specified in such extraordinary resolution or to refrain from
enforcing any such covenant or right;

 

		(d)	to waive, authorize and direct the Warrant Agent to waive any default on the part of the Company
in complying with any provisions of this Indenture or the Warrants either unconditionally or upon any conditions specified in such
extraordinary resolution;

Legislation, such mandatory requirement shall prevail.

 

(2)           The
Company and the Warrant Agent agree that each will at all times in relation to this Indenture and any action to be taken hereunder
observe and comply with and be entitled to the benefit of Applicable Legislation.

(2)           In
the exercise of the rights and duties prescribed or conferred by the terms of this Indenture, the Warrant Agent shall act honestly
and in good faith and shall exercise the degree of care, diligence and skill that a reasonably prudent warrant agent would exercise
in comparable circumstances. No provision of this Indenture shall be construed to relieve the Warrant Agent from, or require any
other person to indemnify the Warrant Agent against liability for its own gross negligence, wilful misconduct, bad faith or fraud.

 

(3)           The
Warrant Agent shall not be bound to do or take any act, action or proceeding for the enforcement of any of the obligations of the
Company under this Indenture unless and until it shall have received a Warrantholders’ Request specifying the act, action
or proceeding that the Warrant Agent is requested to take. The obligation of the Warrant Agent to commence or continue any act,
action or proceeding for the purpose of enforcing any rights of the Warrant Agent or the Warrantholders hereunder shall be conditional
upon the Warrantholders furnishing, when required by notice in writing by the Warrant Agent, sufficient funds to commence or continue
such act, action or proceeding and an indemnity reasonably satisfactory to the Warrant Agent and its counsel to protect and hold
harmless the Warrant Agent, its officers, directors, employees, agents, successors and assigns against the costs, charges and expenses
and liabilities to be incurred thereby and any loss and damage it may suffer by reason thereof. None of the provisions contained
in this Indenture shall require the Warrant Agent to expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties or in the exercise of any of its rights or powers unless indemnified and funded as aforesaid.

 

    	 	- 35 -	 

     

    

  

(4)          The
Warrant Agent may, before commencing any act, action or proceeding, or at any time during the continuance thereof require the Warrantholders
at whose instance it is acting to deposit with the Warrant Agent the Warrants held by them, for which Warrants the Warrant Agent
shall issue receipts.

 

(5)           Every
provision of this Indenture that, by its terms, relieves the Warrant Agent of liability or entitles it to rely upon any evidence
submitted to it is subject to the provisions of Applicable Legislation, this section 8.2 and section 8.3.

 

(6)           The
Warrant Agent shall not be bound to give any notice or do or take any act, action or proceeding by virtue of the powers conferred
on it hereunder unless and until it shall have been required to do so under the terms hereof; nor shall the Warrant Agent be required
to take notice of any default hereunder, unless and until notified in writing of such default, which notice shall specifically
set out the default desired to be brought to the attention of the Warrant Agent and in the absence of such notice the Warrant Agent
may for all purposes of this Indenture conclusively assume that no default has occurred or been made in the performance or observance
of the representations, warranties and covenants, agreements or conditions herein contained. Any such notice shall in no way limit
any discretion herein given to the Warrant Agent to determine whether or not the Warrant Agent shall take action with respect to
any default.

 

(7)           In
this Indenture, whenever confirmations or instructions are required to be given to the Warrant Agent, in order to be valid, such
confirmations and instructions shall be in writing.

 

		8.3	Evidence, Experts and Advisers

 

(1)           In
addition to the reports, certificates, opinions and other evidence required by this Indenture, the Company shall furnish to the
Warrant Agent such additional evidence of compliance with any provision hereof and in such form as may be prescribed by Applicable
Legislation or as the Warrant Agent may reasonably require by written notice to the Company.

 

(2)           In
the exercise of its rights and duties hereunder, the Warrant Agent may, if it is acting in good faith, act and rely absolutely
as to the truth of the statements and the accuracy of the opinions expressed therein, upon statutory declarations, opinions, reports,
written requests, consents, or orders of the Company, certificates of the Company or other evidence furnished to the Warrant Agent
pursuant to any provision hereof or of Applicable Legislation or pursuant to a request of the Warrant Agent. The Warrant Agent
shall be under no responsibility in respect of the validity of this Indenture or the execution and delivery hereof by or on behalf
of the Company or in respect of the validity or the execution of any Warrant Certificate by the Company and issued hereunder, nor
shall it be responsible for any breach by the Company of any covenant or condition contained in this Indenture or in any such Warrant
Certificate; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation
of any securities to be issued upon the right to acquire provided for in this Indenture and/or in any Warrant or as to whether
any securities will when issued be duly authorized or be validly issued and fully paid and non-assessable.

Applicable Legislation requires that evidence referred to in subsection 8.3(1) be in the form of a statutory declaration,

signed, sent or presented by or on behalf of the proper party or parties. The Warrant Agent shall be protected in acting and relying
upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, letter or other paper
document received in facsimile or e-mail form.

 

(6)           The
Warrant Agent may employ or retain such counsel, accountants, engineers, appraisers or other experts or advisers as it may reasonably
require for the purpose of determining and discharging its duties hereunder and may pay reasonable remuneration for all services
so performed by any of them, without taxation of costs of any counsel and shall not be responsible for any misconduct on the part
of any of them who has been selected with due care by the Warrant Agent. Any reasonable remuneration paid by the Warrant Agent

or the Warrant Agent, in relation to any matter arising in fulfilling its duties and obligations hereof.

 

(8)           The

Warrant Agent shall not be liable for or by reason of any representations, statements of fact or recitals in this Indenture or

(except the representation contained in section 8.9 or in the certificate of the Warrant Agent on the Warrants).

herein contained shall impose any obligation on the Warrant Agent to see to or to require evidence of the registration or filing

(5)           Without
limiting any protection or indemnity of the Warrant Agent under any other provision hereof, or otherwise at law, the Company hereby
agrees to indemnify and hold harmless the Warrant Agent and its directors, officers, agents and employees from and against any
and all liabilities, losses, damages, penalties, claims, actions, suits, costs, expenses and disbursements, including reasonable
legal or advisor fees and disbursements, of whatever kind and nature which may at any time be imposed on, incurred by or asserted
against the Warrant Agent in connection with the performance of its duties and obligations hereunder, other than such liabilities,
losses, damages, penalties, claims, actions, suits, costs, expenses and disbursements arising by reason of the gross negligence,
wilful misconduct, bad faith or fraud of the Warrant Agent. This provision shall survive the resignation or removal of the Warrant
Agent, or the termination of this Indenture. The Warrant Agent shall not be under any obligation to prosecute or defend any action
or suit in respect of this Indenture which, in the opinion of its counsel, may involve it in expense or liability, unless the Company
shall, so often as required, furnish the Warrant Agent with satisfactory indemnity and funding against such expense or liability.

 

(6)           If
any of the funds provided to the Warrant Agent hereunder are received by it in the form of an uncertified cheque or bank draft,
the Warrant Agent shall delay the release of such funds and the related Warrant Shares until such uncertified cheque has cleared
the financial institution upon which the same is drawn.

 

(7)           The
forwarding of a cheque or the sending of funds by wire transfer by the Warrant Agent will satisfy and discharge the liability of
any amounts due to the extent of the sum represented thereby unless such cheque is not honoured on presentation, provided that
in the event of the non-receipt of such cheque by the payee, or the loss or destruction thereof, the Warrant Agent, upon being
furnished with reasonable evidence of such non-receipt, loss or destruction and indemnity reasonably satisfactory to it, will issue
to such payee a replacement cheque for the amount of such cheque.

 

(8)           The
Warrant Agent shall retain the right not to act and shall not be liable for refusing to act if, due to a lack of information or
for any other reason whatsoever, the Warrant Agent, in its sole judgement, determines that such act might cause it to be in non-compliance
with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline. Further, should the Warrant Agent,
in its sole judgement, determine at any time that its acting under this Warrant Indenture has resulted in its being in non-compliance
with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline, then it shall have the right
to resign on 10 days’ written notice to the Company provided: (i) that the Warrant Agent’s written notice shall
describe the circumstances of such non-compliance; and (ii) that if such circumstances are rectified to the Warrant Agent’s
satisfaction within such 10-day period, then such resignation shall not be effective.

Warrant Agent shall not be liable for any error in judgment or for any act done or step taken or omitted by it in good faith or
for any mistake, in fact or law, or for anything which it may do or refrain from doing in connection herewith except arising out

by extraordinary resolution shall have the power at any time to remove the existing Warrant Agent and to appoint a new Warrant
Agent. In the event of the Warrant Agent resigning or being removed as aforesaid or being dissolved, becoming bankrupt, going into
liquidation or otherwise becoming incapable of acting hereunder, the Company shall forthwith appoint a new Warrant Agent unless

Agent or any Warrantholder may apply to a judge of the Province of Ontario at the Company’s expense, on such notice as such
judge may direct, for the appointment of a new Warrant Agent; but any new Warrant Agent so appointed by the Company or by the Court

shall be a corporation authorized to carry on the business of a transfer agent or a trust company in the Province of Ontario and,
if required by Applicable Legislation of any other province, in such other province. On any such appointment the new Warrant Agent
shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as Warrant
Agent without any further assurance, conveyance, act or deed; but there shall be immediately executed, at the expense of the Company,
all such conveyances or other instruments as may, in the opinion of counsel, be necessary or advisable for the purpose of assuring
the same to the new Warrant Agent, provided that any resignation or removal of the Warrant Agent and appointment of a successor
Warrant Agent shall not become effective until the successor Warrant Agent shall have executed an appropriate instrument accepting
such appointment and, at the request of the Company, the predecessor Warrant Agent, upon payment of its outstanding remuneration
and expenses, shall execute and deliver to the successor Warrant Agent an appropriate instrument transferring to such successor
Warrant Agent all rights and powers of the Warrant Agent hereunder and all securities, documents of title and other instruments
and all monies and properties held by the Warrant Agent hereunder.

 

(2)           Upon
the appointment of a successor Warrant Agent, the Company shall promptly notify the Warrantholders thereof in the manner provided
for in section 9.1.

 

(3)           Any
corporation into or with which the Warrant Agent may be merged or consolidated or amalgamated, or to which all or substantially
all of the corporate trust business is sold or any corporation succeeding to the stock transfer business of the Warrant Agent,
shall be the successor to the Warrant Agent hereunder without any further act on its part or of any of the parties hereto, provided
that such corporation would be eligible for appointment as a new Warrant Agent under subsection 8.8(1).

 

(4)           Any
Warrants Authenticated or certified but not delivered by a predecessor Warrant Agent may be Authenticated or certified by the new
or successor Warrant Agent in the name of the predecessor or the new or successor Warrant Agent.

Warrant Agent represents to the Company that at the time of execution and delivery hereof no material conflict of interest exists
which it is aware of in the Warrant Agent’s role hereunder and agrees that in the event of a material conflict of interest
arising which it becomes aware of hereafter it will, within 90 days after ascertaining that it has such a material conflict
of interest, either eliminate the same or resign its appointment hereunder. If any such material conflict of interest exists or
hereafter shall exist, the validity and enforceability of this Indenture and the Warrants shall not be affected in any manner whatsoever
by reason thereof.

of a change of address which, from the effective date of such notice and until changed by like notice, shall be the address of
the Company or the Warrant Agent, as the case may be, for all purposes of this Indenture. A copy of any notice of change of address
given pursuant to this subsection 9.1(2) shall be available for inspection at the principal stock transfer offices of the
Warrant Agent in the City of Toronto, Ontario by Warrantholders during normal business hours.

 

(3)           If,
by reason of a strike, lockout or other work stoppage, actual or threatened, involving postal employees, any notice to be given
to the Warrant Agent or to the Company hereunder could reasonably be considered unlikely to reach its destination, the notice shall
be valid and effective only if it is delivered to an officer of the party to which it is addressed or if it is delivered to that
party at the appropriate address provided in subsection 9.1(1) by facsimile, email or other means of prepaid, transmitted
or recorded communication and any notice delivered in accordance with the foregoing shall be deemed to have been received on the

(1)           Any
notice to the Warrantholders under the provisions of this Indenture shall be deemed to be validly given if the notice is sent by
prepaid mail or, if delivered by hand, to the holders at their addresses appearing in the register of holders. Any notice so delivered
shall be deemed to have been received on the date of delivery if that date is a Business Day or the Business Day following the
date of delivery if such date is not a Business Day or on the third Business Day if delivered by mail. All notices may be given
to whichever one of the Warrantholders (if more than one) is named first in the appropriate register hereinbefore mentioned, and
any notice so given shall be sufficient notice to all Warrantholders and any other persons (if any) interested in such Warrants.
Accidental error or omission in giving notice or accidental failure to mail notice to any Warrantholder will not invalidate any
action or proceeding founded thereon.

 

(2)           If,
by reason of strike, lockout or other work stoppage, actual or threatened, involving postal employees, any notice to be given to
the Warrantholders could reasonably be considered unlikely to reach its destination, the notice may be given in a news release
disseminated through a newswire service, filed on SEDAR and posted on the Company’s website; provided that in the case of
a notice convening a meeting of the holders of Warrants, the Warrant Agent may require such additional publications of that notice,
in Toronto, Ontario or in other cities or both, as it may deem necessary for the reasonable notification of the holders of Warrants
or to comply with any applicable requirement of law or any stock exchange. Any notice so given shall be deemed to have been given
on the day on which it has been published in all of the cities in which publication was required.

FORM OF WARRANT CERTIFICATE

 

WARRANTS TO PURCHASE COMMON SHARES

OF PROFOUND MEDICAL CORP.

(a corporation incorporated pursuant to the laws of Ontario)

 

CUSIP No. n

ISIN No. n

 

	Warrant Certificate Number: •	Representing • Warrants to
	 	purchase Common Shares

 

THIS CERTIFIES
that, for value received, the registered holder hereof, • (the “holder”) is entitled, subject to Profound
Medical Corp.’s (the “Company”) right to accelerate the expiry time in certain circumstances, at any time
at or before 5:00 p.m. (Toronto time) on March 20, 2023 (the “Expiry Time”) to acquire, subject to adjustment
in certain events, the number of common shares (“Common Shares”) of the Company specified above, as presently
constituted, by surrendering to TSX Trust Company (the “Warrant Agent”) at its principal office in Toronto,
Ontario, this Warrant Certificate with the duly completed and executed Exercise Form endorsed on the back of this Warrant Certificate,
and accompanied by payment of $1.40 per Common Share (subject to adjustment in certain events) (the “Warrant Exercise
Price”) by certified cheque, bank draft or money order in lawful money of Canada payable to, or to the order of, the
Company at par at the above-mentioned office of the Warrant Agent. The holder of this Warrant Certificate may purchase less than
the number of Common Shares which he is entitled to purchase on the exercise of the Warrants represented by this Warrant Certificate,
in which event a new Warrant Certificate representing the Warrants not then exercised will be issued to the holder.

 

If at any time on or
after the date that is 18 months from March 20, 2018, the closing trading price of the Common Shares on the TSX Venture Exchange
(“TSXV”) (or if the Common Shares are not listed on the TSXV, then on such other recognized Canadian stock exchange
on which the Common Shares are then listed) exceeds $2.80 for a period of 90 consecutive calendar days, the Company shall be entitled,
within 30 days of the occurrence of such event, to accelerate the Expiry Time of the Warrants to a period ending on the date that
is 20 days from the date that notice of such acceleration (the “Acceleration Notice”) is given to the Warrantholders
pursuant to a press release issued by the Company, with the new Expiry Time specified in such Acceleration Notice. From and after
the new Expiry Time specified in such Acceleration Notice, no Warrants may be issued or exercised, and all unexercised Warrants
shall be void and of no effect following the new Expiry Time. The Company shall give prompt written notice of such acceleration
to the Warrant Agent pursuant to section 9.1. For greater certainty, the new Expiry Time specified in an Acceleration Notice shall
not be later than 5:00 p.m. (Toronto Time) on March 20, 2023.

 

    	 	- A-1 -	 

     

    

 

The Warrants evidenced
hereby are exercisable on or before the Expiry Time, after which time the Warrants evidenced hereby shall be deemed to be void
and of no further force or effect.

 

This Warrant Certificate
represents Warrants of the Company issued or issuable under the provisions of a warrant indenture (which indenture together with
all other instruments supplemental or ancillary thereto is herein referred to as the “Warrant Indenture”) dated
as of March 20, 2018, between the Company and the Warrant Agent, as may be amended from time to time, which contains particulars
of the rights of the holders of the Warrants and the Company and of the Warrant Agent in respect thereof and the terms and conditions
upon which the Warrants are issued and held, all to the same effect as if the provisions of the Warrant Indenture were herein set
forth, to all of which the holder of this Warrant Certificate by acceptance hereof assents. Unless otherwise defined herein, all
capitalized terms shall have the meanings ascribed to them in the Warrant Indenture. A copy of the Warrant Indenture will be available
for inspection at the principal office of the Company in the City of Mississauga, Ontario. In the event of any conflict between
the provisions contained in this Warrant Certificate and the provisions of the Warrant Indenture, the provisions of the Warrant
Indenture shall prevail.

 

Upon acceptance hereof,
the holder hereof hereby expressly waives the right to receive any fractional Common Shares upon the exercise hereof in full or
in part and further waives the right to receive any cash or other consideration in lieu thereof. The Warrants represented by this
Warrant Certificate shall be deemed to have been surrendered, and payment by certified cheque, bank draft or money order shall
be deemed to have been made only upon personal delivery thereof or, if sent by post or other means of transmission, upon actual
receipt thereof by the Warrant Agent at its office in the City of Toronto, Ontario.

 

Upon due exercise of
the Warrants represented by this Warrant Certificate and payment of the Warrant Exercise Price, the Company shall cause to be issued
to the person(s) in whose name(s) the Common Shares so subscribed for (provided that if the Common Shares are to be issued to a
person other than the registered holder of this Warrant Certificate, the holder’s signature on the Exercise Form herein shall
be guaranteed by a Schedule I Canadian chartered bank, or by a medallion signature guarantee from a member of a recognized
Signature Medallion Guarantee Program and the holder shall pay to the Company or the Warrant Agent all applicable transfer or similar
taxes and the Company shall not be required to issue or deliver certificates evidencing the Common Shares unless or until the holder
shall have paid the Company or the Warrant Agent the amount of such tax (or shall have satisfied the Company that such tax has
been paid or that no tax is due)) are to be issued, the number of Common Shares to be issued to such person(s) and such person(s)
shall become a holder in respect of such Common Shares with effect from the date of such exercise, and upon due surrender of this
Warrant Certificate and all other documentation required, the Warrant Agent shall cause the issuance of a certificate(s) representing
such Common Shares to be issued within three Business Days after the exercise of the Warrants (or portion thereof) represented
hereby.

 

    	 	- A-2 -	 

     

    

 

Neither the Warrants
represented by this Warrant Certificate nor the Common Shares issuable upon exercise hereof have been or will be registered under
the U.S. Securities Act or any state securities laws. The Warrants represented by this Warrant Certificate may not be
exercised within the United States or by, or for the account or benefit of, a U.S. Person (as defined by Regulation S
under the U.S. Securities Act) or a person within the United States unless registered under the U.S. Securities Act
and any applicable state securities laws or unless an exemption from such registration is available.

 

The holder acknowledges
that the Warrants represented by this Warrant Certificate and the Common Shares issuable upon exercise hereof may be offered, sold
or otherwise transferred only in compliance with all applicable securities laws.

 

No transfer of any
Warrant will be valid unless entered on the register of transfers, upon surrender to the Warrant Agent of the Warrant Certificate
evidencing such Warrant, duly endorsed by, or accompanied by a transfer form or other written instrument of transfer in form satisfactory
to the Warrant Agent executed by the registered holder or his executors, administrators or other legal representatives or his or
their attorney duly appointed by an instrument in writing in form and execution satisfactory to the Warrant Agent. Subject to the
provisions of the Warrant Indenture and upon compliance with the reasonable requirements of the Warrant Agent, Warrant Certificates
may be exchanged for Warrant Certificates representing in the aggregate an equal number of Warrants. The Company and the Warrant
Agent may treat the registered holder of this Warrant Certificate for all purposes as the absolute owner hereof. The holding of
the Warrants represented by this Warrant Certificate shall not constitute the holder hereof a holder of Common Shares nor entitle
him to any right or interest in respect thereof except as herein and in the Warrant Indenture expressly provided.

 

The Warrant Indenture
provides for adjustment in the number of Common Shares to be delivered upon exercise of the right of purchase hereby granted and
to the Warrant Exercise Price in certain events therein set forth.

 

The Warrant Indenture
contains provisions making binding upon all holders of Warrants outstanding thereunder resolutions passed at meetings of such holders
held in accordance with such provisions and instruments in writing signed by the Warrantholders holding a specified percentage
of the then outstanding Warrants.

 

The Warrants and the
Warrant Indenture shall be governed by and performed, construed and enforced in accordance with the laws of the Province of Ontario
and the federal laws of Canada applicable therein and shall be treated in all respects as Ontario contracts. Time shall be of the
essence hereof and of the Warrant Indenture.

 

The Company may from
time to time at any time prior to the Expiry Time purchase any of the Warrants by private agreement or otherwise.

 

This Warrant Certificate
shall not be valid for any purpose until it has been certified by or on behalf of the Warrant Agent for the time being under the
Warrant Indenture.

 

All dollar amounts
herein are expressed in the lawful money of Canada.
