A
maximum of [●] Warrants (subject to adjustment as herein provided) are hereby created and authorized to be issued in accordance
with the terms and conditions hereof. The Corporation hereby agrees that up to [●] Warrants (excluding the application of any Penalty
Provision) shall be issued in accordance with the terms and conditions hereof, upon exercise of the Special Warrants for Units consisting

Corporation, the Warrant Agent shall deliver Warrants in certificate or uncertificated form pursuant to Section 2.5 hereof to Registered
Warrantholders and record the name of the Registered Warrantholders on the Warrant register. Registration of interests in Warrants held
by the Depository may be evidenced by a position appearing on the register for Warrants of the Warrant Agent for an amount representing
the aggregate number of such Warrants outstanding from time to time.

 

Section
2.2 Terms of Warrants.

 

	(1)	Subject
    to the applicable conditions for exercise set out in Article 3 having been satisfied and subject to adjustment in accordance with
    Section 4.1, each whole Warrant shall entitle each Warrantholder thereof, upon exercise at any time after the Issue Date and prior
    to the Expiry Time, to acquire one (1) Warrant Share upon payment of the Exercise Price.
	 	 
	(2)	No
    fractional Warrants shall be issued or otherwise provided for hereunder and Warrants may only be exercised in a sufficient number
    to acquire whole numbers of Warrant Shares. Any fractional Warrants shall be rounded up to the next greater whole number if the fractional
    entitlement is equal to or greater than 0.5 and shall, without any additional compensation, be rounded down to the next lesser whole
    number if the entitlement is less than 0.5 and, in calculating such fractional interest, all Warrants subscribed by such Warrantholder
    shall be aggregated.
	 	 
	(3)	Each
    whole Warrant shall entitle the holder thereof to such other rights and privileges as are set forth in this Indenture.
	 	 
	(4)	The
    number of Warrant Shares which may be purchased pursuant to the Warrants and the Exercise Price therefor shall be adjusted upon the
    events and in the manner specified in Section 4.1.

    may not lawfully be issued pursuant to applicable securities legislation. The Corporation or the Warrant Agent may require any person
    to provide proof of an applicable exemption from such securities legislation to the Corporation and Warrant Agent before Warrant
    Shares are delivered pursuant to the exercise of any Warrant.

Section
2.3 Warrantholder not a Shareholder.

 

Except
as may be specifically provided herein, nothing in this Indenture or in the holding of a Warrant Certificate, entitlement to a Warrant
or otherwise, shall, in itself, confer or be construed as conferring upon a Warrantholder any right or interest whatsoever as a Shareholder,

of the Corporation, or the right to Dividends and other allocations.

    as of the Issue Date, shall bear such distinguishing letters and numbers as the Corporation may, with the approval of the Warrant

	(2)	Each
    Warrantholder by purchasing such Warrant acknowledges and agrees that the terms and conditions set forth in the form of the Warrant
    Certificate set out in Schedule “A” hereto shall apply to all Warrants and Warrantholders regardless of whether such
    Warrants are issued in certificated or uncertificated form or whether such Warrantholders are Registered Warrantholders or owners
    of Warrant who beneficially hold security entitlements in respect of the Warrants through a Depository.

    of beneficial interests in and transfers of Warrants held by the Depository shall be made only through the book-entry registration
    system and no Warrant Certificates shall be issued in respect of such Warrants except where physical certificates evidencing ownership
    in such securities are required or as set out herein or as may be requested by the Depository, as determined by the Corporation,

	 	(c)	the
    Depository ceases to be a clearing agency or otherwise ceases to be eligible to be a depository and the Corporation is unable to
    locate a qualified successor;
	 	 	 
	 	(d)	the
    Corporation determines that the Warrants shall no longer be held as Book-Entry Warrants through the Depository;
	 	 	 
	 	(e)	such
    right is required by Applicable Legislation, as determined by the Corporation and the Corporation’s Counsel;
	 	 	 
	 	(f)	the
    Warrant is to be Authenticated to or for the account or benefit of a U.S. Purchaser; or
	 	 	 
	 	(g)	such

	(3)	Subject
    to the provisions of this Section 2.6, any exchange of CDS Global Warrants for Warrants which are not CDS Global Warrants may be
    made in whole or in part in accordance with the provisions of Section 2.11, mutatis mutandis. All such Warrants issued in exchange
    for a CDS Global Warrant or any portion thereof shall be registered in such names as the Depository for such CDS Global Warrants
    shall direct and shall be entitled to the same benefits and be subject to the same terms and conditions (except insofar as they relate
    specifically to CDS Global Warrants) as the CDS Global Warrants or portion thereof surrendered upon such exchange.
	 	 
	(4)	Every
    Warrant that is Authenticated upon registration or transfer of a CDS Global Warrant, or in exchange for or in lieu of a CDS Global
    Warrant or any portion thereof, whether pursuant to this Section 2.6, or otherwise, shall be Authenticated in the form of, and shall
    be, a CDS Global Warrant, unless such Warrant is registered in the name of a person other than the Depository for such CDS Global
    Warrant or a nominee thereof.
	 	 
	(5)	Notwithstanding
    anything to the contrary in this Indenture, subject to Applicable Legislation, the CDS Global Warrant will be issued as an Uncertificated
    Warrant, unless otherwise requested in writing by the Depository or the Corporation.
	 	 
	(6)	The
    rights of beneficial owners of Warrants who hold securities entitlements in respect of the Warrants through the book-entry registration
    system shall be limited to those established by Applicable Legislation and agreements between the Depository and the Book-Entry Participants
    and between such Book-Entry Participants and the beneficial owners of Warrants who hold securities entitlements in respect of the
    Warrants through the book-entry registration system, and such rights must be exercised through a Book-Entry Participant in accordance
    with the rules and procedures of the Depository.
	 	 
	(7)	Notwithstanding
    anything herein to the contrary, neither the Corporation nor the Warrant Agent nor any agent thereof shall have any responsibility
    or liability for:

 

    	 

    	-10-

    

 

	 	(a)	the
    electronic records maintained by the Depository relating to any ownership interests or any other interests in the Warrants or the
    depository system maintained by the Depository, or payments made on account of any ownership interest or any other interest of any
    person in any Warrant represented by an electronic position in the book-entry registration system (other than the Depository or its

	 	(b)	maintaining,
    supervising or reviewing any records of the Depository or any Book-Entry Participant relating to any such interest; or

	(8)	The
    Corporation may terminate the application of this Section 2.6 in its sole discretion in which case all Warrants shall be evidenced
    by Warrant Certificates registered in the name of a Person other than the Depository.

 

Section
2.7 Warrant Certificate.

 

	(1)	For
    Warrants issued in certificated form, the form of certificate representing such Warrants shall be substantially as set out in Schedule
    “A” hereto or such other form as is authorized from time to time by the Warrant Agent. Each Warrant Certificate shall
    be Authenticated on behalf of the Warrant Agent. Each Warrant Certificate shall be signed by any duly authorized signatories of the
    Corporation; whose signature shall appear on the Warrant Certificate and may be printed, lithographed or otherwise mechanically reproduced
    thereon and, in such event, certificates so signed are as valid and binding upon the Corporation as if it had been signed manually.
    The Warrant Certificates may be engraved, printed or lithographed, or partly in one form and partly in another, as the Warrant Agent
    may determine.
	 	 
	(2)	The
    Warrant Agent shall Authenticate Uncertificated Warrants (whether upon original issuance, exchange, registration of transfer, partial
    payment, or otherwise) by completing its Internal Procedures and the Corporation shall, and hereby acknowledges that it shall, thereupon
    be deemed to have duly and validly issued such Uncertificated Warrants under this Indenture. Such Authentication shall be conclusive
    evidence that such Uncertificated Warrant has been duly issued hereunder and that the holder or holders are entitled to the benefits
    of this Indenture. The register shall be final and conclusive evidence as to all matters relating to Uncertificated Warrants with
    respect to which this Indenture requires the Warrant Agent to maintain records or accounts. In case of differences between the register
    at any time and any other time the register at the later time shall be controlling, absent manifest error and such Uncertificated
    Warrants are binding on the Corporation.
	 	 
	(3)	Any
    Warrant Certificate validly issued in accordance with the terms of this Indenture in effect at the time of issue of such Warrant
    Certificate shall, subject to the terms of this Indenture and Applicable Legislation, validly entitle the holder to acquire Warrant
    Shares, notwithstanding that the form of such Warrant Certificate may not be in the form currently required by this Indenture.
	 	 
	(4)	No
    Warrant shall be considered issued and shall be valid or obligatory or shall entitle the holder thereof to the benefits of this Indenture,
    until it has been Authenticated by the Warrant Agent. Authentication by the Warrant Agent, including by way of entry on the register,
    shall not be construed as a representation or warranty by the Warrant Agent as to the validity of this Indenture or of such Warrant
    Certificates or Uncertificated Warrants (except the due Authentication thereof) or as to the performance by the Corporation of its
    obligations under this Indenture and the Warrant Agent shall in no respect be liable or answerable for the use made of the Warrants
    or any of them or of the consideration thereof. Authentication by the Warrant Agent shall be conclusive evidence as against the Corporation
    that the Warrants so Authenticated have been duly issued hereunder and that the holder thereof is entitled to the benefits of this
    Indenture.

 

    	 

    	-11-

    Warrant Certificate shall be considered issued and Authenticated or, if Authenticated, shall be obligatory or shall entitle the holder
    thereof to the benefits of this Indenture, until it has been Authenticated by signature by or on behalf of the Warrant Agent substantially
    in the form of the Warrant set out in Schedule “A” hereto. Such Authentication on any such Warrant Certificate shall
    be conclusive evidence that such Warrant Certificate is duly Authenticated and is valid and a binding obligation of the Corporation
    and that the holder is entitled to the benefits of this Indenture.
	 	 
	(6)	No
    Uncertificated Warrant shall be considered issued and shall be obligatory or shall entitle the holder thereof to the benefits of
    this Indenture, until it has been Authenticated by entry on the register of the particulars of the Uncertificated Warrant. Such entry
    on the register of the particulars of an Uncertificated Warrant shall be conclusive evidence that such Uncertificated Warrant is
    a valid and binding obligation of the Corporation and that the holder is entitled to the benefits of this Indenture.

 

Section
2.8 Legends.

 

	(1)	Neither
    the Warrants nor the Warrant Shares have been registered under the U.S. Securities Act or under any United States state securities
    laws. If required under United States securities laws, Warrant Certificates originally issued for the benefit or account of a U.S.
    Purchaser and each Warrant Certificate issued in exchange therefor or in substitution thereof shall bear the following legends or
    such variations thereof as the Corporation may prescribe from time to time:

 

“THE
SECURITIES REPRESENTED HEREBY AND THE SECURITIES ISSUABLE UPON EXERCISE HEREOF HAVE NOT BEEN AND WILL NOT BE REGISTERED UNDER THE U.S.
SECURITIES ACT OF 1933, AS AMENDED (THE “U.S. SECURITIES ACT”). THE HOLDER HEREOF, BY PURCHASING SUCH SECURITIES, AGREES
FOR THE BENEFIT OF THE CORPORATION THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY (A) TO THE CORPORATION,
(B) OUTSIDE THE UNITED STATES IN COMPLIANCE WITH RULE 904 OF REGULATION S UNDER THE U.S. SECURITIES ACT AND IN COMPLIANCE WITH ALL LOCAL
LAWS AND REGULATIONS, (C) PURSUANT TO THE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE U.S. SECURITIES ACT PROVIDED BY RULE 144
THEREUNDER, IF AVAILABLE, AND IN COMPLIANCE WITH APPLICABLE STATE SECURITIES LAWS, OR (D) IN ANOTHER TRANSACTION THAT DOES NOT REQUIRE
REGISTRATION UNDER THE U.S. SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAWS, AND IN THE CASE OF (B), (C) OR (D), THE HOLDER HAS
PRIOR TO SUCH SALE FURNISHED TO THE CORPORATION AN OPINION OF COUNSEL OR OTHER EVIDENCE OF EXEMPTION IN FORM AND SUBSTANCE REASONABLY
SATISFACTORY TO THE CORPORATION. DELIVERY OF THIS CERTIFICATE MAY NOT CONSTITUTE “GOOD DELIVERY” IN SETTLEMENT OF TRANSACTIONS
ON STOCK EXCHANGES IN CANADA.”

 

provided
that the legend may be removed by delivery to the Corporation and the Warrant Agent of an opinion of counsel of recognized standing or
other evidence of exemption in form and substance reasonably satisfactory to the Corporation that such legend is no longer required under
applicable requirements of the U.S. Securities Act or state securities laws.

 

The
Warrant Agent shall be entitled to request any other documents that it may reasonably require in accordance with its internal policies
for the removal of the legend set forth above.

 

	(2)	Each
                                            CDS Global Warrant, if issued on a certificated basis, originally issued in Canada and held
                                            by the Depository, and each CDS Global Warrant issued in exchange therefor or in substitution
                                            thereof shall bear or be deemed to bear the following legend or such variations thereof as
                                            the Corporation may prescribe from time to time:

 

    	 

    	-12-

    

 

“UNLESS
THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF CDS CLEARING AND DEPOSITORY SERVICES INC. (“CDS”) TO THE
CORPORATION OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IN RESPECT THEREOF IS REGISTERED
IN THE NAME OF CDS & CO, OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF CDS (AND ANY PAYMENT IS MADE TO
CDS & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF CDS), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF
FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED HOLDER HEREOF, CDS & CO., HAS A PROPERTY INTEREST IN
THE SECURITIES REPRESENTED BY THIS CERTIFICATE HEREIN AND IT IS A VIOLATION OF ITS RIGHTS FOR ANOTHER PERSON TO HOLD, TRANSFER OR DEAL
WITH THIS CERTIFICATE.”

 

	(3)
    	Each
    Warrant Certificate originally issued in Canada or to a Canadian holder and each CDS Global Warrant originally issued in Canada and
    held by the Depository prior to the date a Receipt is issued by the Principal Regulator, (and each such Warrant Certificate or CDS
    Global Warrant, as the case may be, issued in exchange therefor or in substitution thereof prior to the date a Receipt is issued
    by the Principal Regulator) shall bear or be deemed to bear the following legend or such variations thereof as the Corporation my
    prescribe from time to time:

 

“UNLESS
PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THIS SECURITY BEFORE [THE DATE THAT IS 4 MONTHS AND
A DAY AFTER THE CLOSING DATE].”

 

Each
Warrant Certificate originally issued in Canada or to a Canadian holder and each CDS Global Warrant originally issued in Canada and held
by the Depository after the Principal Regulator has issued a Receipt will not bear the legend in this Section 2.8(3).

 

	(4)	Notwithstanding
    any other provisions of this Indenture, in processing and registering transfers of Warrants, no duty or responsibility whatsoever
    shall rest upon the Warrant Agent to determine the compliance by any transferor or transferee with the terms of the legend contained
    in Section 2.8(1) or Section 2.8(2), or with the relevant securities laws or regulations, including, without limitation, Regulation
    S, and the Warrant Agent shall be entitled to assume that all transfers are legal and proper.

 

Section
2.9 Register of Warrants

 

	(1)	The
    Warrant Agent shall maintain records and accounts concerning the Warrants, whether certificated or uncertificated, which shall contain
    the information called for below with respect to each Warrant, together with such other information as may be required by law or
    as the Warrant Agent may elect to record. All such information shall be kept in one set of accounts and records which the Warrant
    Agent shall designate (in such manner as shall permit it to be so identified as such by an unaffiliated party) as the register of
    the holders of Warrants. The information to be entered for each account in the register of Warrants at any time shall include (without
    limitation):

 

	 	(a)	the
    name and address of the Registered Warrantholder, the date of Authentication thereof and the number of Warrants;
	 	 	 
	 	(b)	whether
    such Warrant is a Warrant Certificate or an Uncertificated Warrant and, if a Warrant Certificate, the unique number or code assigned
    to and imprinted thereupon and, if an Uncertificated Warrant, the unique number or code assigned thereto if any;
	 	 	 
	 	(c)	whether
    such Warrant has been cancelled; and
	 	 	 
	 	(d)	a
    register of transfers in which all transfers of Warrants and the date and other particulars of each transfer shall be entered.

 

    	 

    	-13-

    

 

The
register shall be available for inspection by the Corporation and or any Warrantholder during the Warrant Agent’s regular business
hours on a Business Day and upon payment to the Warrant Agent of its reasonable fees. Any Warrantholder exercising such right of inspection
shall first provide an affidavit in form satisfactory to the Corporation and the Warrant Agent stating the name and address of the Warrantholder
and agreeing not to use the information therein except in connection with an effort to call a meeting of Warrantholders or to influence
the voting of Warrantholders at any meeting of Warrantholders.

 

	(2)	Once
    an Uncertificated Warrant has been Authenticated, the information set forth in the register with respect thereto at the time of Authentication
    may be altered, modified, amended, supplemented or otherwise changed only to reflect exercise or proper instructions to the Warrant
    Agent from the holder as provided herein, except that the Warrant Agent may act unilaterally to make purely administrative changes
    internal to the Warrant Agent and changes to correct errors. Each person who becomes a holder of an Uncertificated Warrant, by his,
    her or its acquisition thereof shall be deemed to have irrevocably (i) consented to the foregoing authority of the Warrant Agent
    to make such minor error corrections and (ii) agreed to pay to the Warrant Agent, promptly upon written demand, the full amount of
    all loss and expense (including without limitation reasonable legal fees of the Corporation and the Warrant Agent plus interest,
    at an appropriate then prevailing rate of interest to the Warrant Agent), sustained by the Corporation or the Warrant Agent as a
    proximate result of such error if but only if and only to the extent that such present or former holder realized any benefit as a
    result of such error and could reasonably have prevented, forestalled or minimized such loss and expense by prompt reporting of the
    error or avoidance of accepting benefits thereof whether or not such error is or should have been timely detected and corrected by
    the Warrant Agent; provided, that no person who is a bona fide purchaser shall have any such obligation to the Corporation or to
    the Warrant Agent.

 

Section
2.10 Issue in Substitution for Warrant Certificates Lost, etc.

 

	(1)	If
    any Warrant Certificate becomes mutilated or is lost, destroyed or stolen, the Corporation, subject to applicable law, shall issue
    and thereupon the Warrant Agent shall certify and deliver, a new Warrant Certificate of like tenor, and bearing the same legend,
    if applicable, as the one mutilated, lost, destroyed or stolen in exchange for and 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 in a form approved by the Warrant Agent and the Warrants evidenced thereby shall be entitled to the
    benefits hereof and shall rank equally in accordance with its terms with all other Warrants issued or to be issued hereunder.
	 	 
	(2)	The
    applicant for the issue of a new Warrant Certificate pursuant to this Section 2.10 shall bear the cost of the issue thereof and in
    case of loss, destruction or theft shall, as a condition precedent to the issuance thereof, furnish to the Corporation 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 Corporation and to the Warrant Agent, in their sole discretion, and such applicant shall also be
    required to furnish an indemnity and surety bond in amount and form satisfactory to the Corporation and the Warrant Agent, in their
    sole discretion, and shall pay the reasonable charges of the Corporation and the Warrant Agent in connection therewith.

 

Section
2.11 Exchange of Warrant Certificates.

 

	(1)	Any
    one or more Warrant Certificates representing any number of Warrants may, upon compliance with the reasonable requirements of the
    Warrant Agent (including compliance with applicable securities legislation), be exchanged for one or more other Warrant Certificates
    representing the same aggregate number of Warrants, and bearing the same legend, if applicable, as represented by the Warrant Certificate
    or Warrant Certificates so exchanged.

 

    	 

    	-14-

    

 

	(2)	Warrant
    Certificates may be exchanged only at the Warrant Agency or at any other place that is designated by the Corporation with the approval
    of the Warrant Agent. Any Warrant Certificate from the holder (or such other instructions, in form satisfactory to the Warrant Agent),
    tendered for exchange shall be surrendered to the Warrant Agency and cancelled by the Warrant Agent.
	 	 
	(3)
    	Warrant
    Certificates exchanged for Warrant Certificates that bear the legend or legends set forth in Section 2.8(1) shall bear the same legend
    or legends.

 

Section
2.12 Transfer and Ownership of Warrants.

 

	(1)	The
    Warrants may only be transferred on the register kept by the Warrant Agent at the Warrant Agency by the holder or its legal representatives
    or its attorney duly appointed by an instrument in writing in form and execution satisfactory to the Warrant Agent only upon (a)
    in the case of a Warrant Certificate, surrendering to the Warrant Agent at the Warrant Agency the Warrant Certificates representing
    the Warrants to be transferred together with a duly executed transfer form as set forth in Schedule “A” attached hereto,
    (b) in the case of Book-Entry Warrants, in accordance with procedures prescribed by the Depository under the book-entry registration
    system, and (c) upon compliance with:

 

	 	(i)	the
    conditions herein;
	 	 	 
	 	(ii)	such
    reasonable requirements as the Warrant Agent may prescribe; and
	 	 	 
	 	(iii)	all
    applicable securities legislation and requirements of regulatory authorities;

 

	 	and
    such transfer shall be duly noted in such register by the Warrant Agent. Upon compliance with such requirements, the Warrant Agent
    shall issue to the transferee of a Warrant Certificate, a Warrant Certificate and to the transferee of an Uncertificated Warrant,
    an Uncertificated Warrant, or the Warrant Agent shall Authenticate and deliver a Warrant Certificate upon request that part of the
    CDS Global Warrant be certificated. Transfers within the systems of the Depository are not the responsibility of the Warrant Agent
    and will not be noted on the register maintained by the Warrant Agent.

 

	(2)	If
    a Warrant Certificate tendered for transfer bears any of the legends set forth in Section 2.8(1), the Warrant Agent shall not register
    such transfer unless the transferor has provided the Warrant Agent with the Warrant Certificate and (A) the transfer is made to the
    Corporation or (B) an opinion of counsel of recognized standing, reasonably satisfactory to the Corporation that the proposed transfer
    is exempt from registration with applicable state laws and the U.S. Securities Act and that such legends may be removed.
	 	 
	(3)	Subject
    to the provisions of this Indenture, Applicable Legislation and applicable law, the Warrantholder shall be entitled to the rights
    and privileges attaching to the Warrants, and the issue of Warrant Shares by the Corporation upon the exercise of Warrants in accordance
    with the terms and conditions herein contained shall discharge all responsibilities of the Corporation and the Warrant Agent with
    respect to such Warrants and neither the Corporation nor the Warrant Agent shall be bound to inquire into the title of any such holder.

 

Section
2.13 Cancellation of Surrendered Warrants.

 

All
Warrant Certificates surrendered pursuant to Article 3 shall be cancelled by the Warrant Agent and upon such circumstances all such Uncertificated
Warrants shall be deemed cancelled and so noted on the register by the Warrant Agent. Upon request by the Corporation, the Warrant Agent
shall furnish to the Corporation a cancellation certificate identifying the Warrant Certificates so cancelled, the number of Warrants
evidenced thereby, the number of Warrant Shares, if any, issued pursuant to such Warrants and the details of any Warrant Certificates
issued in substitution or exchange for such Warrant Certificates cancelled.

EXERCISE
OF WARRANTS

 

Section
3.1 Right of Exercise.

 

Subject
to the provisions hereof, each Registered Warrantholder may exercise the right conferred on such holder to subscribe for and purchase
one (1) Warrant Share for each Warrant after the Issue Date and prior to the Expiry Time and in accordance with the conditions herein.

 

If
no Registration Statement is effective under the U.S. Securities Act, or if the Prospectus contained therein is not available
for the offer and sale of the Common Shares issuable upon exercise of the Warrants, at any time prior to the Expiry Time, such Warrantholder
shall be notified forthwith by the Warrant Agent that such Warrantholder is entitled to a cashless exercise, in accordance with Section
3.3.

 

Section
3.2 Warrant Exercise.

 

	(1)	Other
    than Warrants held by the Depository, Registered Warrantholders of Warrant Certificates who wish to exercise the Warrants held by
    them in order to acquire Warrant Shares must complete the exercise form (the “Exercise Notice”) attached to the
    Warrant Certificate(s) which form is attached hereto as Schedule “B”, which may be amended by the Corporation with the
    consent of the Warrant Agent, if such amendment does not, in the reasonable opinion of the Corporation and the Warrant Agent, which
    may be based on the advice of Counsel, materially and adversely affect the rights, entitlements and interests of the Warrantholders,
    and deliver such certificate(s), the executed Exercise Notice and a certified cheque, bank draft or money order payable to or to
    the order of the Corporation for the aggregate Exercise Price to the Warrant Agent at the Warrant Agency. The Warrants represented
    by a Warrant Certificate shall be deemed to be surrendered upon personal delivery of such certificate, Exercise Notice and aggregate
    Exercise Price or, if such documents are sent by mail or other means of transmission, upon actual receipt thereof by the Warrant
    Agent at the office referred to above.
	 	 
	(2)	In
    addition to completing the Exercise Notice attached to the Warrant Certificate(s), a U.S. Purchaser must provide an opinion of counsel
    of recognised standing in form and substance reasonably satisfactory to the Corporation that the exercise is exempt from the registration
    requirements of applicable securities laws of any state of the United States and the U.S. Securities Act; provided however
    that in the case of a U.S. Purchaser that is the original U.S. Purchaser, such U.S. Purchaser will not be required to deliver an
    opinion of counsel in connection with the due exercise of the Warrants at a time when the representations, warranties and covenants
    made by the U.S. Purchaser in the U.S. Accredited Investor Certificate remain true and correct and the U.S. Purchaser represents
    to the Corporation as such.
	 	 
	(3)	A
    Registered Warrantholder of Uncertificated Warrants evidenced by a security entitlement in respect of Warrants must complete the
    Exercise Notice and deliver the executed Exercise Notice and a certified cheque, bank draft or money order payable to or to the order
    of the Corporation for the aggregate Exercise Price to the Warrant Agent at the Warrant Agency. The Uncertificated Warrants shall
    be deemed to be surrendered upon receipt of the Exercise Notice and aggregate Exercise Price or, if such documents are sent by mail
    or other means of transmission, upon actual receipt thereof by the Warrant Agent at the office referred to above.
	 	 
	(4)	A
    beneficial owner of Uncertificated Warrants evidenced by a security entitlement in respect of Warrants in the book-entry registration
    system who desires to exercise his or her Warrants must do so by causing a Book-Entry Participant to withdraw the Warrant from the
    book-entry registration system. Upon withdrawal of the Warrant, an individually registered Warrant Certificate shall be issued by
    the Warrant Agent to such beneficial owner or Book-Entry Participant and the exercise procedures set forth in forth in Section 3.2(1)
    shall be followed.

 

    	 

    	-16-

    

 

	(5)	Payment
    representing the aggregate Exercise Price must be provided to the appropriate office of the Book-Entry Participant in a manner acceptable
    to it. A notice in form acceptable to the Book-Entry Participant and payment from such beneficial holder should be provided to the
    Book-Entry Participant sufficiently in advance so as to permit the Book-Entry Participant to deliver notice and payment to
    the Warrant Agent prior to the Expiry Time. The beneficial owner or Book-Entry Participant will initiate the exercise by way of the
    instructions received from the beneficial owner and forward the aggregate Exercise Price electronically to the Warrant Agent and
    the Warrant Agent will execute the exercise by issuing to the beneficial owner or Book-Entry Participant the Warrant Shares to which
    the exercising Warrantholder is entitled pursuant to the exercise. Any expense associated with the exercise process will be for the
    account of the entitlement holder exercising the Warrants and/or the Book-Entry Participant exercising the Warrants on its behalf.
	 	 
	(6)	By
    causing a Book-Entry Participant to deliver notice to the Warrant Agent, a Warrantholder shall be deemed to have irrevocably surrendered
    his or her Warrants so exercised and appointed such Book-Entry 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.
	 	 
	(7)	Any
    notice which the Warrant Agent determines to be incomplete, not in proper form or not duly executed shall for all purposes be void
    and of no force and effect and the exercise to which it relates shall be considered for all purposes not to have been exercised thereby.
    A failure by a Book-Entry Participant to exercise or to give effect to the settlement thereof in accordance with the Warrantholder’s
    instructions will not give rise to any obligations or liability on the part of the Corporation or Warrant Agent to the Book-Entry
    Participant or the Warrantholder.
	 	 
	(8)	The
    Exercise Notice referred to in this Section 3.2 shall be signed by the Registered Warrantholder, or its executors or administrators
    or other legal representativess or an attorney of the Registered Warrantholder, duly appointed by an instrument in writing satisfactory
    to the Warrant Agent.
	 	 
	(9)	Any
    exercise referred to in this Section 3.2 shall require that the entire Exercise Price for Warrant Shares subscribed must be paid
    at the time of subscription and such Exercise Price and original Exercise Notice executed by the Registered Warrantholder must be
    received by the Warrant Agent prior to the Expiry Time.
	 	 
	(10)	Warrants
    may only be exercised pursuant to this Section 3.2 by or on behalf of a Registered Warrantholder, as applicable, who makes the certifications
    set forth on the Exercise Notice set out in Schedule “B” or as provided herein.
	 	 
	(11)	If
    the form of Exercise Notice set forth in the Warrant Certificate shall have been amended, the Corporation shall cause the amended
    Exercise Notice to be forwarded to all Registered Warrantholders.
	 	 
	(12)	Exercise
    Notices must be delivered to the Warrant Agent at any time during the Warrant Agent’s actual business hours on any Business
    Day prior to the Expiry Time. Any Exercise Notice received by the Warrant Agent after business hours on any Business Day other than
    the Expiry Date will be deemed to have been received by the Warrant Agent on the next following Business Day.
	 	 
	(13)	Any
    Warrant with respect to which a Exercise Notice is not received by the Warrant Agent before the Expiry Time shall be deemed to have
    expired and become void and all rights with respect to such Warrants shall terminate and be cancelled.

 

Section
3.3 Cashless Exercise of Warrants

 

	(1)	If,
    at the time of exercise of any Warrant in accordance with this Indenture, there is no effective Registration Statement under the
    U.S. Securities Act, or the Prospectus contained therein is not available for the offer and sale of the Common Shares to the
    Warrantholder under the U.S. Securities Act, then the Warrants may only be exercised, in whole or in part, at such time by means
    of a “cashless exercise” in which the Warrantholder shall be entitled to receive a number of Common Shares equal to the
    quotient obtained by dividing [(A-B) (X)] by (A), where:

 

    	 

    	-17-

    

 

	 	A
    =	the
    last Current Market Price immediately preceding the time of delivery of the Exercise Form giving rise to the applicable “cashless
    exercise” (to clarify, the “last Current Market Price” will be the last Current Market Price as calculated over
    an entire Trading Day such that, in the event that a Warrant is exercised at a time when the CSE is open, the prior Trading Day’s
    Current Market Price shall be used in this calculation);
	 	 	 
	 	B
    =	the
    Exercise Price of the Warrant, as adjusted hereunder (if any); and
	 	 	 
	 	X
    =	the
    number of Common Shares that would be issuable upon exercise of the Warrant in accordance with the terms of such Warrant if such
    exercise were by means of a cash exercise rather than a cashless exercise.

 

	(2)	If
    Common Shares are issued pursuant to such a cashless exercise, the parties acknowledge and agree that in accordance with Section
    3(a)(9) of the U.S. Securities Act, such Common Shares shall take on the registered characteristics of the Warrants being exercised.
    The Corporation agrees not to take any position contrary to this Section 3.3(2).
	 	 
	(3)	Upon
    receipt of a duly completed Subscription Form that specifies a cashless exercise, the Warrant Agent will notify the Corporation,
    which will calculate and provide in writing to the Warrant Agent the number of Common Shares to be allotted to the Warrantholder.
	 	 
	(4)	Any
    Warrantholder that holds Warrants registered in the name of CDS and that wishes to exercise such Warrants under this section by means
    of a cashless exercise must first withdraw their position from CDS, arrange to have the applicable Warrant certificated and surrender
    such warrant certificate to the Warrant Agent for exercise by means of a “cashless exercise”.

 

For
the avoidance of doubt, a Warrantholder may only exercise his or her warrants by means of “cashless exercise” if there is
no effective registration statement under the U.S. Securities Act registering, or the Prospectus contained therein is not available
for, the offer and issuance of the Common Shares to the Warrantholder upon the exercise of his or her Warrants. If there is an effective
registration statement under the U.S. Securities Act registering, or the Prospectus contained therein is available for, the offer
and issuance of the Common Shares to the Warrantholder upon the exercise of his or her Warrants, such Warrantholder may only exercise
his or her Warrants in accordance with Section 3.2. Furthermore, the Warrant Agent shall not be held liable for any exercise carried
out by a Warrantholder that should have been carried out by means of a “cashless exercise” as described herein.

 

Section
3.4 Restrictions on Exercise by U.S. Persons; Legended Certificates

 

	(1)	Subject
    to Section 3.4(2) below, (i) Warrants may not be exercised within the United States or by or on behalf of any U.S. Person; and (ii)
    no Warrant Shares issued upon exercise of Warrants may be delivered to any address in the United States.
	 	 
	(2)	Notwithstanding
    Section 3.4(1), Warrants which bear the legend set forth in Section 2.8(1) may be exercised in the United States or by or on behalf
    of a U.S. Person, and Warrant Shares issued upon exercise of any such Warrants may be delivered to an address in the United States,
    provided that (a) the Person exercising the Warrants is an Accredited Investor and (b) delivers a completed and executed Exercise
    Notice and (if the Warrantholder is not a U.S. Purchaser) provides in form and substance reasonably satisfactory to the Corporation
    a legal opinion which confirms that issuance of shares is in compliance with the applicable state securities laws and the U.S. Securities
    Act; provided however that in the case of a U.S. Purchaser that is the original purchaser of the Special Warrants and who
    delivered the U.S. Accredited Investor Certificate attached to the subscription agreement of the Corporation in connection with its
    purchase of Special Warrants in the private placement pursuant to which the Warrants were issued, such U.S. Purchaser will not be
    required to deliver an opinion of counsel in connection with the due exercise of the Warrants at a time when the representations,
    warranties and covenants made by the U.S. Purchaser in the U.S. Accredited Investor Certificate remain true and correct and the U.S.
    Purchaser represents to the Corporation as such.

 

    	 

    	-18-

    

 

	(3)	Certificates
    representing Warrant Shares issued upon the exercise of Warrants which bear the legend set forth in Section 2.8(1) or which are issued
    and delivered pursuant to Section 3.4(2) shall bear the following legend:

 

“THE
SECURITIES REPRESENTED HEREBY HAVE NOT BEEN AND WILL NOT BE REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “U.S.
SECURITIES ACT”). THE HOLDER HEREOF, BY PURCHASING SUCH SECURITIES, AGREES FOR THE BENEFIT OF THE CORPORATION THAT SUCH SECURITIES
MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY (A) TO THE CORPORATION, (B) OUTSIDE THE UNITED STATES IN COMPLIANCE WITH
RULE 904 OF REGULATION S UNDER THE U.S. SECURITIES ACT AND IN COMPLIANCE WITH ALL LOCAL LAWS AND REGULATIONS, (C) PURSUANT TO THE EXEMPTION
FROM THE REGISTRATION REQUIREMENTS OF THE U.S. SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER, IF AVAILABLE, AND IN COMPLIANCE WITH APPLICABLE
STATE SECURITIES LAWS, OR (D) IN ANOTHER TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE U.S. SECURITIES ACT OR ANY APPLICABLE
STATE SECURITIES LAWS, AND IN THE CASE OF (B), (C) OR (D), THE HOLDER HAS PRIOR TO SUCH SALE FURNISHED TO THE CORPORATION AN OPINION
OF COUNSEL OR OTHER EVIDENCE OF EXEMPTION IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE CORPORATION. DELIVERY OF THIS CERTIFICATE
MAY NOT CONSTITUTE “GOOD DELIVERY” IN SETTLEMENT OF TRANSACTIONS ON STOCK EXCHANGES IN CANADA.”;

 

Provided
that the above legend may be removed by delivery to the Corporation and the registrar and transfer agent of an opinion of counsel of
recognized standing, or other evidence, in form and substance reasonably satisfactory to the Corporation, to the effect that such legend
is no longer required under applicable requirements of the U.S. Securities Act or state securities laws.

 

	(4)	Certificates
    representing Warrant Shares issued upon the exercise of Warrant Certificates (and issued in substitution or exchange therefor) prior
    to the date that is four months and one day after the date hereof and if issued prior to the date a Receipt is issued by the Principal
    Regulator shall bear the following legend:

 

“UNLESS
PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THIS SECURITY BEFORE [THE DATE THAT IS 4 MONTHS AND
A DAY AFTER THE CLOSING DATE].”

 

Section
3.5 Transfer Fees and Taxes.

 

If
any of the Warrant Shares subscribed for are to be issued to a person or persons other than the Registered Warrantholder, the Registered
Warrantholder shall execute the form of transfer and will comply with such reasonable requirements as the Warrant Agent may stipulate
and will pay to the Corporation or the Warrant Agent on behalf of the Corporation, all applicable transfer or similar taxes and the Corporation
will not be required to issue or deliver certificates evidencing Warrant Shares unless or until such Warrantholder shall have paid to
the Corporation or the Warrant Agent on behalf of the Corporation, the amount of such tax or shall have established to the satisfaction
of the Corporation and the Warrant Agent that such tax has been paid or that no tax is due.

 

    	 

    	-19-

    

 

Section
3.6 Warrant Agency.

 

To
facilitate the exchange, transfer or exercise of Warrants and compliance with such other terms and conditions hereof as may be required,
the Corporation has appointed the Warrant Agency, as the agency at which Warrants may be surrendered for exchange or transfer or at which
Warrants may be exercised and the Warrant Agent has accepted such appointment. The Corporation may from time to time designate alternate
or additional places as the Warrant Agency (subject to the Warrant Agent’s prior approval) and will give notice to the Warrant
Agent of any proposed change of the Warrant Agency. Branch registers shall also be kept at such other place or places, if any, as the
Corporation, with the approval of the Warrant Agent, may designate. The Warrant Agent will from time to time when requested to do so
by the Corporation or any Registered Warrantholder, upon payment of the Warrant Agent’s reasonable charges, furnish a list of the
names and addresses of Registered Warrantholders showing the number of Warrants held by each such Registered Warrantholder.

 

Section
3.7 Effect of Exercise of Warrant Certificates.

 

	(1)	Upon
    the exercise of Warrants Certificates pursuant to and in compliance with Section 3.2 and subject to Section 3.3 and Section 3.5,
    the Warrant Shares to be issued pursuant to the Warrants exercised shall be deemed to have been issued and the person or persons
    to whom such Warrant Shares are to be issued shall be deemed to have become the holder or holders of such Warrant Shares within three
    (3) Business Days of the Exercise Date unless the register shall be closed on such date, in which case the Warrant Shares subscribed
    for shall be deemed to have been issued and such person or persons deemed to have become the holder or holders of record of such
    Warrant Shares, on the date on which such register is reopened. It is hereby understood that in order for persons to whom Warrant
    Shares are to be issued, to become holders of Warrant Shares on record on the Exercise Date, beneficial holders must commence the
    exercise process sufficiently in advance so that the Warrant Agent is in receipt of all items of exercise at least one Business Day
    prior to such Exercise Date.
	 	 
	(2)	Within
    three (3) Business Days after the Exercise Date with respect to a Warrant, the Warrant Agent shall use commercially reasonable efforts
    to cause to be delivered or mailed to the person or persons in whose name or names the Warrant is registered or, if so specified
    in writing by the holder, cause to be delivered to such person or persons at the Warrant Agency where the Warrant Certificate was
    surrendered, a certificate or certificates for the appropriate number of Warrant Shares subscribed for, or any other appropriate
    evidence of the issuance of Warrant Shares to such person or persons in respect of Warrant Shares issued under the book-entry registration
    system.

 

Section
3.8 Partial Exercise of Warrants; Fractions.

 

	(1)	The
    holder of any Warrants may exercise his right to acquire a number of whole Warrant Shares less than the aggregate number which the
    holder is entitled to acquire. In the event of any exercise of a number of Warrants less than the number which the holder is entitled
    to exercise, the holder of Warrants upon such exercise shall, in addition, be entitled to receive, without charge therefor, a new
    Warrant Certificate(s), bearing the same legend, if applicable, or other appropriate evidence of Warrants, in respect of the balance
    of the Warrants held by such holder and which were not then exercised.
	 	 
	(2)	Notwithstanding
    anything herein contained including any adjustment provided for in Section 4.1, the Corporation shall not be required, upon the exercise
    of any Warrants, to issue fractions of Warrant Shares. Warrants may only be exercised in a sufficient number to acquire whole numbers
    of Warrant Shares. Any fractional Warrant Shares shall be rounded up to the next greater whole number if the fractional entitlement
    is equal to or greater than 0.5 and shall, without any additional compensation, be rounded down to the next lesser whole number if
    the fractional entitlement is less than 0.5 and, in calculating such fractional interests, all Warrant Shares held by such Warrantholder
    shall be aggregated;

 

    	 

    	-20-

    

 

Section
3.9 Expiration of Warrants.

 

Immediately
after the Expiry Time, all rights under any Warrant in respect of which the right of acquisition provided for herein shall not have been
exercised shall cease and terminate and each Warrant shall be void and of no further force or effect.

 

Section
3.10 Accounting and Recording.

 

	(1)	The
    Warrant Agent shall promptly account to the Corporation with respect to Warrants exercised, and shall promptly forward to the Corporation
    (or into an account or accounts of the Corporation with the bank or trust company designated by the Corporation for that purpose),
    all monies received by the Warrant Agent on the subscription of Warrant Shares through the exercise of Warrants. All such monies
    and any securities or other instruments, from time to time received by the Warrant Agent, shall be received in trust for, and shall
    be segregated and kept apart by the Warrant Agent, the Warrantholders and the Corporation as their interests may appear
	 	 
	(2)	The
    Warrant Agent shall record the particulars of Warrants exercised, which particulars shall include the names and addresses of the
    persons who become holders of Warrant Shares on exercise and the Exercise Date, in respect thereof. The Warrant Agent shall provide
    such particulars in writing to the Corporation within three (3) Business Days of any request by the Corporation therefor.

 

Section
3.11 Securities Restrictions

 

Notwithstanding
anything herein contained, Warrant Shares will be issued upon exercise of a Warrant only in compliance with the securities laws of any
applicable jurisdiction.

 

Article

ADJUSTMENT
OF NUMBER OF Warrant SHARES

AND
EXERCISE PRICE

 

Section
4.1 Adjustment of Number of Warrant Shares and Exercise Price.

 

The
subscription rights in effect under the Warrants for Warrant Shares issuable upon the exercise of the Warrants shall be subject to adjustment
from time to time as follows:

 

	 	(a)	if,
    at any time during the Adjustment Period, the Corporation shall:

 

	 	(i)	subdivide,
    re-divide or change its outstanding Common Shares into a greater number of Common Shares;
	 	 	 
	 	(ii)	reduce,
    combine or consolidate its outstanding Common Shares into a lesser number of Common Shares; or
	 	 	 
	 	(iii)	issue
    Common Shares or securities exchangeable for, or convertible into, Common Shares to all or substantially all of the holders of Common
    Shares by way of stock dividend or other distribution (other than a distribution of Common Shares upon the exercise of Warrants or
    any outstanding options);

 

    	 

    	-21-

    

 

(any
of such events in Section 4.1(a)(i), (ii) or (iii) being called a “Common Share Reorganization”) then the Exercise Price
shall be adjusted as of the effect on the effective date or record date of such subdivision, re-division, change, reduction, combination,
consolidation or distribution, as the case may be, shall in the case of the events referred to in (i) or (iii) above be decreased in
proportion to the number of outstanding Common Shares resulting from such subdivision, re-division, change or distribution, or shall,
in the case of the events referred to in (ii) above, be increased in proportion to the number of outstanding Common Shares resulting
from such reduction, combination or consolidation by multiplying the Exercise Price in effect immediately prior to such effective date
or record date by a fraction, the numerator of which shall be the number of Common Shares outstanding on such effective date or record
date before giving effect to such Common Share Reorganization and the denominator of which shall be the number of Common Shares outstanding
as of the effective date or record date after giving effect to such Common Share Reorganization (including, in the case where securities
exchangeable for or convertible into Common Shares are distributed, the number of Common Shares that would have been outstanding had
such securities been exchanged for or converted into Common Shares on such record date or effective date). Such adjustment shall be made
successively whenever any event referred to in this Section 4.1(a) shall occur. Upon any adjustment of the Exercise Price pursuant to
Section 4.1(a), the Exchange Rate shall be contemporaneously adjusted by multiplying the number of Common Shares theretofore obtainable
on the exercise thereof by a fraction of which the numerator shall be the Exercise Price in effect immediately prior to such adjustment
and the denominator shall be the Exercise Price resulting from such adjustment;

 

	(b)	if
    and whenever at any time during the Adjustment Period, the Corporation shall fix a record date for the issuance of rights, options
    or warrants to all or substantially all the holders of its outstanding Common Shares entitling them, for a period expiring not more
    than 45 days after such record date, to subscribe for or purchase Common Shares (or securities convertible or exchangeable into Common
    Shares) at a price per Common Share (or having a conversion or exchange price per Common Share) less than 95% of the Current Market
    Price on such record date (a “Rights Offering”), the Exercise Price shall be adjusted immediately after such record
    date so that it shall equal the amount determined by multiplying the Exercise Price in effect on such record date by a fraction,
    of which the numerator shall be the total number of Common Shares outstanding on such record date plus a number of Common Shares
    equal to the number arrived at by dividing the aggregate price of the total number of additional Common Shares offered for subscription
    or purchase (or the aggregate conversion or exchange price of the convertible or exchangeable securities so offered) by the Current
    Market Price, and of which the denominator shall be the total number of Common Shares outstanding on such record date plus the total
    number of additional Common Shares offered for subscription or purchase or into which the convertible or exchangeable securities
    so offered are convertible or exchangeable; any Common Shares owned by or held for the account of the Corporation shall be deemed
    not to be outstanding for the purpose of any such computation; such adjustment shall be made successively whenever such a record
    date is fixed; to the extent that no such rights or warrants are exercised prior to the expiration thereof, the Exercise Price shall
    be readjusted to the Exercise Price which would then be in effect if such record date had not been fixed or, if any such rights or
    warrants are exercised, to the Exercise Price which would then be in effect based upon the number of Common Shares (or securities
    convertible or exchangeable into Common Shares) actually issued upon the exercise of such rights or warrants, as the case may be.
    Upon any adjustment of the Exercise Price pursuant to this Section 4.1(b), the Exchange Rate will be adjusted immediately after such
    record date so that it will equal the rate determined by multiplying the Exchange Rate in effect on such record date by a fraction,
    of which the numerator shall be the Exercise Price in effect immediately prior to such adjustment and the denominator shall be the
    Exercise Price resulting from such adjustment. Such adjustment will be made successively whenever such a record date is fixed, provided
    that if two or more such record dates or record dates referred to in this Section 4.1(b) are fixed within a period of 25 Trading
    Days, such adjustment will be made successively as if each of such record dates occurred on the earliest of such record dates;

 

    	 

    	-22-

    

 

	(c)	if
    and whenever at any time during the Adjustment Period the Corporation shall fix a record date for the making of a distribution to
    all or substantially all the holders of its outstanding Common Shares of (i) securities of any class, whether of the Corporation
    or any other entity (other than Common Shares), (ii) rights, options or warrants to subscribe for or purchase Common Shares (or other
    securities convertible into or exchangeable for Common Shares), other than pursuant to a Rights Offering; (iii) evidences of its
    indebtedness or (iv) any property or other assets then, in each such case, the Exercise Price shall be adjusted immediately after
    such record date so that it shall equal the price determined by multiplying the Exercise Price in effect on such record date by a
    fraction, of which the numerator shall be the total number of Common Shares outstanding on such record date multiplied by the Current
    Market Price on such record date, less the excess, if any, of the fair market value on such record date, as determined by the Corporation
    (whose determination shall be conclusive), of such securities or other assets so issued or distributed over the fair market value
    of any consideration received therefor by the Corporation from the holders of the Common Shares, and of which the denominator shall
    be the total number of Common Shares outstanding on such record date multiplied by the Current Market Price; and Common Shares owned
    by or held for the account of the Corporation shall be deemed not to be outstanding for the purpose of any such computation; such
    adjustment shall be made successively whenever such a record date is fixed; to the extent that such distribution is not so made,
    the Exercise Price shall be readjusted to the Exercise Price which would then be in effect if such record date had not been fixed.
    Upon any adjustment of the Exercise Price pursuant to this Section 4.1(c), the Exchange Rate will be adjusted immediately after such
    record date so that it will equal the rate determined by multiplying the Exchange Rate in effect on such record date by a fraction,
    of which the numerator shall be the Exercise Price in effect immediately prior to such adjustment and the denominator shall be the
    Exercise Price resulting from such adjustment;
	 	 
	(d)	if
    and whenever at any time during the Adjustment Period, there is a reclassification of the Common Shares or a capital reorganization
    of the Corporation other than as described in Section 4.1(a) or a consolidation, amalgamation, arrangement or merger of the Corporation
    with or into any other body corporate, trust, partnership or other entity, or a sale or conveyance of the property and assets of
    the Corporation as an entirety or substantially as an entirety to any other body corporate, trust, partnership or other entity, any
    Registered Warrantholder who has not exercised its right of acquisition prior to the effective date of such reclassification, capital
    reorganization, consolidation, amalgamation, arrangement or merger, sale or conveyance, upon the exercise of such right thereafter,
    shall be entitled to receive upon payment of the Exercise Price and shall accept, in lieu of the number of Warrant Shares that prior
    to such effective date the Registered Warrantholder would have been entitled to receive, the number of shares or other securities
    or property of the Corporation or of the body corporate, trust, partnership or other entity resulting from such merger, amalgamation
    or consolidation, or to which such sale or conveyance may be made, as the case may be, that such Registered Warrantholder would have
    been entitled to receive on such reclassification, capital reorganization, consolidation, amalgamation, arrangement or merger, sale
    or conveyance, if, on the effective date thereof, as the case may be, the Registered Warrantholder had been the registered holder
    of the number of Warrant Shares to which prior to such effective date it was entitled to acquire upon the exercise of the Warrants.
    If determined appropriate by the Warrant Agent, relying on advice of Counsel, to give effect to or to evidence the provisions of
    this Section 4.1(d), the Corporation, its successor, or such purchasing body corporate, partnership, trust or other entity, as the
    case may be, shall, prior to or contemporaneously with any such reclassification, capital reorganization, consolidation, amalgamation,
    arrangement, merger, sale or conveyance, enter into an indenture which shall provide, to the extent possible, for the application
    of the provisions set forth in this Indenture with respect to the rights and interests thereafter of the Registered Warrantholders
    to the end that the provisions set forth in this Indenture shall thereafter correspondingly be made applicable, as nearly as may
    reasonably be, with respect to any shares, other securities or property to which a Registered Warrantholder is entitled on the exercise
    of its acquisition rights thereafter. Any indenture entered into between the Corporation and the Warrant Agent pursuant to the provisions
    of this Section 4.1(d) shall be a supplemental indenture entered into pursuant to the provisions of Article 8 hereof. Any indenture
    entered into between the Corporation, any successor to the Corporation or such purchasing body corporate, partnership, trust or other
    entity and the Warrant Agent shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments
    provided in this Section 4.1 and which shall apply to successive reclassifications, capital reorganizations, amalgamations, consolidations,
    mergers, sales or conveyances;

 

    	 

    	-23-

    

 

	(e)	in
    any case in which this Section 4.1 shall require that an adjustment shall become effective immediately after a record date for an
    event referred to herein, the Corporation may defer, until the occurrence of such event, issuing to the Registered Warrantholder
    of any Warrant exercised after the record date and prior to completion of such event the additional Warrant Shares issuable by reason
    of the adjustment required by such event before giving effect to such adjustment; provided, however, that the Corporation shall deliver
    to such Registered Warrantholder an appropriate instrument evidencing such Registered Warrantholder’s right to receive such
    additional Common Shares upon the occurrence of the event requiring such adjustment and the right to receive any distributions made
    on such additional Common Shares declared in favour of holders of record of Common Shares on and after the relevant date of exercise
    or such later date as such Registered Warrantholder would, but for the provisions of this Section 4.1(e), have become the holder
    of record of such additional Common Shares pursuant to Section 4.1;
	 	 
	(f)	in
    any case in which Section 4.1(a)(iii), Section 4.1(b) or Section 4.1(c) require that an adjustment be made to the Exercise Price,
    no such adjustment shall be made if the Registered Warrantholders of the outstanding Warrants receive, subject to any required stock
    exchange or regulatory approval, the rights or warrants referred to in Section 4.1(a)(iii), Section 4.1(b) or the shares, rights,
    options, warrants, evidences of indebtedness or assets referred to in Section 4.1(c), as the case may be, in such kind and number
    as they would have received if they had been holders of Common Shares on the applicable record date or effective date, as the case
    may be, by virtue of their outstanding Warrant having then been exercised into Common Shares at the Exercise Price in effect on the
    applicable record date or effective date, as the case may be;
	 	 
	(g)	the
    adjustments provided for in this Section 4.1 are cumulative, and shall, in the case of adjustments to the Exercise Price be computed
    to the nearest whole cent and shall apply to successive subdivisions, re-divisions, reductions, combinations, consolidations, distributions,
    issues or other events resulting in any adjustment under the provisions of this Section 4.1, provided that, notwithstanding any other
    provision of this Section, no adjustment of the Exercise Price shall be required unless such adjustment would require an increase
    or decrease of at least 1% in the Exercise Price then in effect; provided, however, that any adjustments which by reason of this
    Section 4.1(g) are not required to be made shall be carried forward and taken into account in any subsequent adjustment; and
	 	 
	(h)	after
    any adjustment pursuant to this Section 4.1, the term “Common Shares” where used in this Indenture shall be interpreted
    to mean securities of any class or classes which, as a result of such adjustment and all prior adjustments pursuant to this Section
    4.1, the Registered Warrantholder is entitled to receive upon the exercise of his Warrant, and the number of Warrant Shares indicated
    by any exercise made pursuant to a Warrant shall be interpreted to mean the number of Warrant Shares or other property or securities
    a Registered Warrantholder is entitled to receive, as a result of such adjustment and all prior adjustments pursuant to this Section
    4.1, upon the full exercise of a Warrant.

 

Section
4.2 Entitlement to Warrant Shares on Exercise of Warrant.

 

All
Common Shares or shares of any class or other securities, which a Registered Warrantholder is at the time in question entitled to receive
on the exercise of its Warrant, whether or not as a result of adjustments made pursuant to this Article 4, shall, for the purposes of
the interpretation of this Indenture, be deemed to be Warrant Shares which such Registered Warrantholder is entitled to acquire pursuant
to such Warrant.

 

    	 

    	-24-

    

 

Section
4.3 No Adjustment for Certain Transactions.

 

Notwithstanding
anything in this Article 4, no adjustment shall be made in the acquisition rights attached to the Warrants if the issue of Common Shares
is being made pursuant to this Indenture or in connection with (a) any share incentive plan or restricted share plan or share purchase
plan in force from time to time for directors, officers, employees, consultants or other service providers of the Corporation; or (b)
the satisfaction of existing instruments issued at the date hereof.

 

Section
4.4 Determination by Independent Firm.

 

In
the event of any question arising with respect to the adjustments provided for in this Article 4 such question shall be conclusively
determined by an independent firm of chartered public accountants other than the Auditors, who shall have access to all necessary records
of the Corporation, and such determination shall be binding upon the Corporation, the Warrant Agent, all holders and all other persons
interested therein.

 

Section
4.5 Proceedings Prior to any Action Requiring Adjustment.

 

As
a condition precedent to the taking of any action which would require an adjustment in any of the acquisition rights pursuant to any
of the Warrants, including the number of Warrant Shares which are to be received upon the exercise thereof, the Corporation shall take
any action which may, in the opinion of Counsel, be necessary in order that the Corporation has unissued and reserved in its authorized
capital and may validly and legally issue as fully paid and non-assessable all the Warrant Shares which the holders of such Warrants
are entitled to receive on the full exercise thereof in accordance with the provisions hereof.

 

Section
4.6 Certificate of Adjustment.

 

The
Corporation shall from time to time immediately after the occurrence of any event which requires an adjustment or readjustment as provided
in Section 4.1, deliver a certificate of the Corporation to the Warrant Agent specifying the nature of the event requiring the same and
the amount of the adjustment or readjustment necessitated thereby and setting forth in reasonable detail the method of calculation and
the facts upon which such calculation is based, which certificate may be supported by a certificate of the Corporation’s Auditors
verifying such calculation if requested by the Warrant Agent at their discretion. The Warrant Agent shall rely, and shall be protected
in so doing, upon the certificate of the Corporation or of the Corporation’s Auditor and any other document filed by the Corporation
pursuant to this Article 4 for all purposes.

 

Section
4.7 Notice of Special Matters.

 

The
Corporation covenants with the Warrant Agent that, so long as any Warrant remains outstanding, it will give notice to the Warrant Agent
and to the Registered Warrantholders of its intention to fix a record date that is prior to the Expiry Date for any matter for which
an adjustment may be required pursuant to Section 4.1 Such notice shall specify the particulars of such event and the record date for
such event, provided that the Corporation shall only be required to specify in the notice such particulars of the event as shall have
been fixed and determined on the date on which the notice is given. The notice shall be given in each case not less than 14 days prior
to such applicable record date. If notice has been given and the adjustment is not then determinable, the Corporation shall promptly,
after the adjustment is determinable, file with the Warrant Agent a computation of the adjustment and give notice to the Registered Warrantholders
of such adjustment computation.

 

Section
4.8 No Action after Notice.

 

The
Corporation covenants with the Warrant Agent that it will not close its transfer books or take any other corporate action which might
deprive the Registered Warrantholder of the opportunity to exercise its right of acquisition pursuant thereto during the period of 14
days after the giving of the certificate or notices set forth in Section 4.6 and Section 4.7.

 

    	 

    	-25-

    

 

Section
4.9 Other Action.

 

If
the Corporation, after the date hereof, shall take any action affecting the Common Shares other than action described in Section 4.1,
which in the reasonable opinion of the directors of the Corporation would materially affect the rights of Registered Warrantholders,
the Exercise Price and/or Exchange Rate, the number of Warrant Shares which may be acquired upon exercise of the Warrants shall be adjusted
in such manner and at such time, by action of the directors, acting reasonably and in good faith, in their sole discretion as they may
determine to be equitable to the Registered Warrantholders in the circumstances, provided that no such adjustment will be made unless
any requisite prior approval of any stock exchange on which the Common Shares are listed for trading has been obtained.

 

Section
4.10 Protection of Warrant Agent.

 

The
Warrant Agent shall not:

 

	 	(a)	at
    any time be under any duty or responsibility to any Registered Warrantholder to determine whether any facts exist which may require
    any adjustment contemplated by Section 4.1, or with respect to the nature or extent of any such adjustment when made, or with respect
    to 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 or of any other securities or property
    which may at any time be issued or delivered upon the exercise of the rights attaching to any Warrant;
	 	 	 
	 	(c)	be
    responsible for any failure of the Corporation to issue, transfer or deliver Warrant Shares or certificates for the same 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; and
	 	 	 
	 	(d)	incur
    any liability or be in any way responsible for the consequences of any breach on the part of the Corporation of any of the representations,
    warranties or covenants herein contained or of any acts of the directors, officers, employees, agents or servants of the Corporation.

 

Section
4.11 Participation by Warrantholder.

 

No
adjustments shall be made pursuant to this Article 4 if the Registered Warrantholders are entitled to participate in any event described
in this Article 4 on the same terms, mutatis mutandis, as if the Registered Warrantholders had exercised their Warrants prior to, or
on the effective date or record date of, such event.

OF THE CORPORATION AND COVENANTS

 

Section
5.1 Optional Purchases by the Corporation.

 

Subject
to compliance with applicable securities legislation and approval of applicable regulatory authorities, if any, the Corporation may from
time to time purchase by private contract 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 directors of the Corporation, 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 Corporation, in its sole discretion, may determine. In the
case of Warrant Certificates, Warrant Certificates representing the Warrants purchased pursuant to this Section 5.1 shall forthwith be
delivered to and cancelled by the Warrant Agent and reflected accordingly on the register of Warrants. In the case of Uncertificated
Warrants, the Warrants purchased pursuant to this Section 5.1 shall be reflected accordingly on the register of Warrants and in accordance
with procedures prescribed by the Depository under the book-entry registration system. No Warrants shall be issued in replacement thereof.

		(a)	it
                                            will reserve and keep available a sufficient number of Common Shares for the purpose of enabling
                                            it to satisfy its obligations to issue Warrant Shares upon the exercise of the Warrants;
	 	 	 
		(b)	it
                                            will cause the Warrant Shares from time to time acquired pursuant to the exercise of the
                                            Warrants to be duly issued and delivered in accordance with the Warrants and the terms hereof;
	 	 	 
		(c)	upon
                                            payment of the aggregate Exercise Price therefor, all Warrant Shares which shall be issued
                                            upon exercise of the right to acquire provided for herein shall be fully paid and non-assessable,
                                            free and clear of all encumbrances;
	 	 	 
		(d)	it
                                            will use reasonable commercial efforts to maintain its existence and carry on its business
                                            in the ordinary course;
	 	 	 
		(e)	generally,
                                            it will well and truly perform and carry out all of the acts or things to be done by it as
                                            provided in this Indenture;
	 	 	 
		(f)	in
                                            the event that both (A) the Receipt is obtained and (B) the Registration Statement has been
                                            declared effective by the SEC, it will give written notice to the Warrant Agent and the Agents
                                            of the issuance of the Receipt and filing of the Registration Statement and specifying the
                                            Qualification Date Expiry, not later than two Business Day after the issuance of such Receipt
                                            and filing of such Registration Statement; and the Company will provide written confirmation
                                            to the Warrant Agent, the Agents and the Warrantholders of any adjustment that has been made;
                                            and
	 	 	 
		(g)	the
                                            Corporation will promptly notify the Warrant Agent and the Warrantholders in writing of any
                                            default under the terms of this Warrant Indenture which remains unrectified for more than
                                            five days following its occurrence.

 

Section
5.3 Warrant Agent’s Remuneration and Expenses.

 

The
Corporation covenants that it will pay to the Warrant Agent from time to time reasonable remuneration for its services hereunder and
will pay or reimburse the Warrant Agent upon its request for all reasonable expenses, disbursements and advances incurred or made by
the Warrant Agent in the administration or execution of its duties hereby created (including the reasonable compensation and the disbursements
of its Counsel and all other advisers and assistants not regularly in its employ) both before any default hereunder and thereafter until
all duties of the Warrant Agent hereunder shall be finally and fully performed. Any amount owing hereunder and remaining unpaid after
30 days from the invoice date will bear interest at the then current rate charged by the Warrant Agent against unpaid invoices and shall
be payable upon demand. This Section shall survive the resignation or removal of the Warrant Agent and/or the termination of this Indenture.

of such failure on the part of the Corporation and may itself perform any of the covenants capable of being performed by it but, subject
to Section 9.2, shall be under no obligation to perform said covenants or to notify the Registered Warrantholders of such performance
by it. All sums expended or advanced by the Warrant Agent in so doing shall be repayable as provided in Section 5.3. No such performance,
expenditure or advance by the Warrant Agent shall relieve the Corporation of any default hereunder or of its continuing obligations under
the covenants herein contained.

 

Section
5.5 Enforceability of Warrants.

 

The
Corporation covenants and agrees that it is duly authorized to create and issue the Warrants to be issued hereunder and that the Warrants,
when issued and Authenticated as herein provided, will be valid and enforceable against the Corporation in accordance with the provisions
hereof and the terms hereof and that, subject to the provisions of this Indenture, the Corporation will cause the Warrant Shares from

provided
that no delay or omission of the Warrant Agent or of the Registered Warrantholders to exercise any right or power accruing upon any default
shall impair any such right or power or shall be construed to be a waiver of any such default or acquiescence therein and provided further
that no act or omission either of the Warrant Agent or of the Registered Warrantholders in the premises shall extend to or be taken in
any manner whatsoever to affect any subsequent default hereunder of the rights resulting therefrom.

The
Warrant Agent may at any time and from time to time, and shall on receipt of a written request of the Corporation or of a Warrantholders’
Request and upon being indemnified and funded to its reasonable satisfaction by the Corporation or by the Registered Warrantholders signing
such Warrantholders’ Request against the costs which may be incurred in connection with the calling and holding of such meeting,

in the manner provided for in Section 10.2 and a copy of such notice shall be sent by mail to the Warrant Agent (unless the meeting has

the time when and the place where the meeting is to be held, shall state briefly the general nature of the business to be transacted
thereat and shall contain such information as is reasonably necessary to enable the Registered Warrantholders to make a reasoned decision

provisions of this Section 7.2.

7.3 Chairman.

 

An
individual (who need not be a Registered Warrantholder) designated in writing by the Warrant Agent shall be chairman of the meeting and

to all the then outstanding Warrants. If a quorum of the Registered Warrantholders shall not be present within thirty minutes from the
time fixed for holding any meeting, the meeting, if summoned by Registered Warrantholders or on a Warrantholders’ Request, shall

                                            the Warrant Agent shall exercise that degree of care, diligence and skill that a reasonably
                                            prudent warrant agent would exercise in comparable circumstances. No provision of this Indenture

                                            to hold harmless the Warrant Agent and its officers, directors, employees and agents, 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 to risk its own funds or otherwise to 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.
	 	 
	(3)	The
                                            Warrant Agent may, before commencing or at any time during the continuance of any such act,
                                            action or proceeding, require the Registered Warrantholders, at whose instance it is acting
                                            to deposit with the Warrant Agent the Warrants Certificates held by them, for which Warrants
                                            the Warrant Agent shall issue receipts.
	 	 
	(4)	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

                                            good faith, rely as to the truth of the statements and the accuracy of the opinions expressed
                                            in statutory declarations, opinions, reports, written requests, consents, or orders of the

                                            requirements of this Indenture.

Section

If,
in any jurisdiction, any provision of this Indenture or its application to any party or circumstance is restricted, prohibited or unenforceable,

in any other jurisdiction or without affecting its application to other parties or circumstances.

 

Section

No
party shall be liable to the other, or held in breach of this Indenture, if prevented, hindered, or delayed in the performance or observance
of any provision contained herein by reason of act of God, riots, terrorism, acts of war, epidemics, governmental action or judicial

Section
10.11 Rights of Rescission and Withdrawal for Holders

 

Should
a holder of Warrants exercise any legal, statutory, contractual or other right of withdrawal or rescission that may be available to it,
and the holder’s funds which were paid on exercise have already been released to the Corporation by the Warrant Agent, the Warrant
Agent shall not be responsible for ensuring the exercise is cancelled and a refund is paid back to the holder. In such cases, the holder
shall seek a refund directly from the Corporation and subsequently, the Corporation, upon surrender to the Corporation or the Warrant
Agent of any underlying Warrant Shares or other securities that may have been issued, or such other procedure as agreed to by the parties
hereto, shall instruct the Warrant Agent in writing, to cancel the exercise transaction and any such underlying Warrant Shares or other
securities on the register, which may have already been issued upon the Warrant exercise. In the event that any payment is received from
the Corporation by virtue of the holder being a shareholder for such Warrants that were subsequently rescinded, such payment must be
returned to the Corporation by such holder. The Warrant Agent shall not be under any duty or obligation to take any steps to ensure or
enforce the return of the funds pursuant to this section, nor shall the Warrant Agent be in any other way responsible in the event that

(the
“Warrantholder”) is the registered holder of the number of common share purchase warrants (the “Warrants”)
of Bunker Hill Mining Corp. (the “Corporation”) specified above, and is entitled, on exercise of these Warrants
upon and subject to the terms and conditions set forth herein and in the Warrant Indenture, to purchase at any time before 5:00 p.m.
(Toronto time) (the “Expiry Time”) on March 31, 2025 (the “Expiry Date”), one fully paid and non-assessable
common stock without par value in the capital of the Corporation as constituted on the date hereof (a “Common Share”)
for each Warrant subject to adjustment in accordance with the terms of the Warrant Indenture.

 

The
right to purchase Common Shares may only be exercised by the Warrantholder within the time set forth above by:

 

(a)
duly completing and executing the exercise form (the “Exercise Form”) attached hereto; and

 

(b)
surrendering this warrant certificate (the “Warrant Certificate”), with the Exercise Form to the Warrant Agent at
the principal office of the Warrant Agent, in the city of Toronto, together with a certified cheque, bank draft or money order in the
lawful money of Canada payable to or to the order of the Corporation in an amount equal to the aggregate Exercise Price of the Common
Shares so subscribed for.

 

The
surrender of this Warrant Certificate, the duly completed Exercise Form and payment as provided above will be deemed to have been effected
only on personal delivery thereof to, or if sent by mail or other means of transmission on actual receipt thereof by, the Warrant Agent
at its principal office as set out above.

 

Pursuant
to Section 3.3 of the Warrant Indenture (as defined below), subject to adjustment thereof in the events and in the manner set forth in
the Warrant Indenture hereinafter referred to, the exercise price payable for each Common Share upon the exercise of Warrants shall be
$0.37 per Common Share (the “Exercise Price”) provided that the Warrants shall be exercisable on a cashless basis
in the event the Registration Statement has not been made effective by the SEC prior to the Exercise Date.

 

Certificates
for the Common Shares subscribed for will be mailed, within three (3) Business Days of such exercise, to the persons specified in the
Exercise Form at their respective addresses specified therein or, if so specified in the Exercise Form, delivered to such persons at
the office where this Warrant Certificate is surrendered. If fewer Common Shares are purchased than the number that can be purchased
pursuant to this Warrant Certificate, the holder hereof will be entitled to receive without charge a new Warrant Certificate in respect
of the balance of the Common Shares not so purchased. No fractional Common Shares will be issued upon exercise of any Warrant.

 

    	 

    	 	A-3	 

    

 

This
Warrant Certificate evidences Warrants of the Corporation 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 [●], 2022 between the Corporation and Capital Transfer Agency ULC, as Warrant Agent, to which Warrant Indenture
reference is hereby made for particulars of the rights of the holders of Warrants, the Corporation and the Warrant Agent in respect thereof
and the terms and conditions on 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, by acceptance hereof, assents. The Corporation will furnish to the holder, on request
and without charge, a copy of the Warrant Indenture.

 

On
presentation at the principal office of the Warrant Agent as set out above, subject to the provisions of the Warrant Indenture and on
compliance with the reasonable requirements of the Warrant Agent, one or more Warrant Certificates may be exchanged for one or more Warrant
Certificates entitling the holder thereof to purchase in the aggregate an equal number of Common Shares as are purchasable under the
Warrant Certificate(s) so exchanged.

 

Neither
the Warrants nor the Common Shares issuable upon exercise hereof have been registered under the United States Securities Act of 1933,
as amended (the “U.S. Securities Act”), or U.S. state securities laws. These Warrants may not be exercised in the United
States or by or on behalf of, or for the account or benefit of, a U.S. Person or a person in the United States unless the Warrants and
the Common Shares issuable upon exercise of the Warrants have been registered under the U.S. Securities Act and the applicable state
securities legislation or an exemption from such registration requirements is available. “United States” and “U.S.
Person” have the meanings ascribed thereto in Regulation S under the U.S. Securities Act.

 

The
Warrant Indenture contains provisions for the adjustment of the Exercise Price payable for each Common Share upon the exercise of Warrants
and the number of Common Shares issuable upon the exercise of Warrants in the events and in the manner set forth therein.

 

The
Warrant Indenture also contains provisions making binding on all holders of Warrants outstanding thereunder resolutions passed at meetings
of holders of Warrants held in accordance with the provisions of the Warrant Indenture and instruments in writing signed by Warrantholders
of Warrants entitled to purchase a specific majority of the Common Shares that can be purchased pursuant to such Warrants.

 

Nothing
contained in this Warrant Certificate, the Warrant Indenture or elsewhere shall be construed as conferring upon the holder hereof any
right or interest whatsoever as a holder of Common Shares or any other right or interest except as herein and in the Warrant Indenture
expressly provided. In the event of any discrepancy between anything contained in this Warrant Certificate and the terms and conditions
of the Warrant Indenture, the terms and conditions of the Warrant Indenture shall govern.

 

Warrants
may only be transferred in compliance with the conditions of the Warrant Indenture on the register to be kept by the Warrant Agent in
Toronto or such other registrar as the Corporation, with the approval of the Warrant Agent, may appoint at such other place or places,
if any, as may be designated, upon surrender of this Warrant Certificate to the Warrant Agent or other registrar accompanied by a written
instrument of transfer in form and execution satisfactory to the Warrant Agent or other registrar and upon compliance with the conditions
prescribed in the Warrant Indenture and with such reasonable requirements as the Warrant Agent or other registrar may prescribe and upon
the transfer being duly noted thereon by the Warrant Agent or other registrar. Time is of the essence hereof.

 

This
Warrant Certificate will not be valid for any purpose until it has been countersigned by or on behalf of the Warrant Agent from time
to time under the Warrant Indenture.

 

The
parties hereto have declared that they have required that these presents and all other documents related hereto be in the English language.
Les parties aux présentes déclarent qu’elles ont exigé que la présente convention, de même que
tous les documents s’y rapportant, soient rédigés en anglais.

FOR TRANSFER – FOR US RESIDENTS ONLY

 

Consistent
with US IRS regulations, Capital Transfer Agency is required to request cost basis information from US securityholders. Please indicate
the reason for requesting the transfer as well as the date of event relating to the reason. The event date is not the day in which the
transfer is finalized, but rather the date of the event which led to the transfer request (i.e. date of gift, date of death of the securityholder,
or the date the private sale took place).

 Exhibit 10.27 

CONFIDENTIAL RETIREMENT AGREEMENT AND RELEASE 

This Confidential Retirement Agreement and Release (the “Agreement”) is entered into between Kenneth Winemaster
(“Winemaster”) and Power Solutions International, Inc. (the “Company”). This Agreement will be effective upon expiration of the revocation period provided in Section 11 of this Agreement (the “Effective Date”).

 BACKGROUND 
 1.
Winemaster currently serves as the Executive Vice President of the Company and is a co-founder of the Company. 

2. Winemaster desires to retire from his position as Executive Vice President and desires to retire from full time employment. 

3. Winemaster and PSI enter into the following Agreement to (a) provide Winemaster with the benefits described below in recognition of
his 36 years of contribution and service to the Company, (b) provide an orderly transition of Winemaster’s responsibilities and keep access to Winemaster’s cooperation regarding Company operations and strategy, (c) avoid any
disputes between them relating to or arising from Winemaster’s employment by the Company or his resignation of employment; and (d) facilitate the Company’s desire to have control over the timing of Winemaster’s resignation of
employment and the Company’s announcement of his retirement. 
 AGREEMENT 

1. Retirement of Employment. Winemaster will voluntarily resign his employment effective January 1, 2022 (the “Retirement Date”).
Winemaster’s retirement will be announced at a mutually agreed time, and in a mutually agreed manner, by a statement prepared by the Company and approved by Winemaster. The Company will continue to employ Winemaster through the Retirement Date
and will continue to provide Winemaster with all compensation and benefits set forth in Paragraph 4 of his Employment Agreement dated September 21, 2017 (“Employment Agreement”) and shall not terminate his employment for any reason
prior to the Retirement Date. 
 2. Retirement Benefits. In consideration for this Agreement, the Company will provide the following
benefits to Winemaster: 
 A. The Company will pay Winemaster severance payments in the total amount of $348,070.08, less applicable
withholdings. Payments of the amount of $348,070.08 shall be payable in twelve monthly installments of $29,005.84 payable by the first day of each month in the months of January 2022 through December 2022. At such time as Company executives are
reimbursed for the 10% reduction in salary instituted July 1 of 2021, but no later than July 1, 2022, the company shall pay Winemaster $16,737, less applicable withholdings, representing the payback of the 10% reduction in salary for
Winemaster from July through December 2021. 
 B. On January 1, 2023 the Company will pay Winemaster $32,500 under the 2019 Long
Term Incentive (LTI) plan, as long as paid to other executive LTI participants for the 2021 LTI plan year as full and complete payment under the LTI plan. 

 C. The Company will maintain Winemaster’s United Airlines Mileage Plus Global
Service status throughout the current term and for one additional term, to the extent the Company continues to participate in the United Airlines miles program. 

D. If Winemaster timely elects COBRA health insurance continuation coverage, the Company will pay a proportional share of the premiums
owed by Winemaster as if Winemaster were still employed by the Company for a period of thirteen months. Winemaster will be responsible for submitting all notices and forms required to elect COBRA. 

Winemaster acknowledges and agrees that he is responsible for the employee’s share of any and all tax liability, if any, arising from the Retirement
Benefits provided in Paragraph 2. 
 3. Indemnification. The Company agrees that the Indemnification Agreement between Winemaster and
the Company dated January 20, 2014 and any duly executed amendments thereto (“Indemnification Agreement”) remains in full force and effect. A true and accurate copy of the Indemnification Agreement is attached hereto as Exhibit A and
is fully incorporated by reference. 
 4. Release. In exchange for the consideration specified in this Agreement, except for claims
specifically exempted from the terms of this Release under the Agreement, Winemaster, on behalf of himself and his heirs, legatees, personal representatives and assigns, releases and discharges the Company, the Company affilliates, and each of their
respective officers, directors, members, managers, partners and shareholders, (collectively, the “Released Parties”) from any and all claims and causes of action, whether known or unknown, that Winemaster has, had or may have against them,
related in any way to his employment with the Company or separation of employment, including any and all claims under the Employment Agreement. This release specifically includes, but is in no way limited to, (i) all claims arising from or
relating in any way to Winemaster’s employment with the Company or his separation from employment with the Company; (ii) all claims under Title VII of the Civil Rights Act of 1964, as amended by the Civil Rights Act of 1991, 42 U.S.C.
§§ 2000e et seq.; the Civil Rights Acts of 1866 and 1871 as amended, 42 U.S.C. § 1981; the Age Discrimination in Employment Act of 1967 as amended, 29 U.S.C. §§ 621 et. seq.; the Americans With Disabilities Act
of 1990, 42 U.S.C. §§ 12101 et seq., as amended; the Equal Pay Act, 29 U.S.C. § 29 U.S.C. § 206(d); the Family and Medical Leave Act of 1993, 29 U.S.C. §§ 2601 et seq., as amended; the Employee Retirement
Income Security Act of 1973 as amended, 29 U.S.C. §§ 1001 et seq.; the Occupational Safety and Health Act of 1970 as amended, 29 U.S.C. §§ 651 et seq.; the Illinois Human Rights Act, 765 ILCS 5/1-101 et seq., the Illinois Whistleblower Act, 740 ILCS 174/1 et seq., or any provision of Chapter 820 of the Illinois Compiled Statutes; and (iv) any other claims or causes of action that
Winemaster has, had, or may have had under any federal, state, or local statute, regulation, ordinance, or the common law. Winemaster waives any right to receive any monetary or other benefit because of any charge, claim, lawsuit, or administrative
proceeding based upon any claim released in this Agreement. This release does not apply to claims for workers’ compensation benefits or other claims that cannot be released under applicable law. For avoidance of doubt, this Release shall not
act to preclude Winemaster from asserting any rights or claims as a Shareholder of the Company and shall not release any claims or modify any rights available to Winemaster under the Indemnification Agreement. Nothing in this Agreement limits
Winemaster’s ability to file a charge or complaint with the Equal Employment Opportunity Commission, the National Labor 

  
 2 

 
Relations Board, the Occupational Safety and Health Administration, the Securities and Exchange Commission or any other federal, state, or local government agency or commission (“Government
Agencies”), but Winemaster waives his right to recover damages from PSI should any agency pursue a claim on his behalf. Winemaster further understands that this Agreement does not limit his ability to communicate with any Government Agencies or
otherwise participate in any investigation or proceeding that may be conducted by any Government Agency. Nothing in this Agreement is intended to prevent, impede or interfere with Winemaster providing truthful testimony and information in the course
of an investigation authorized by law and conducted by any Government Agencies. 
 5. Cooperation. Winemaster agrees to make himself
reasonably available to assist in any transition related duties as requested by the Company. Winemaster also agrees to provide reasonable assistance to the Company and the Company’s attorneys upon request in connection with any, strategy or
industry issues that Winemaster has been working on and as to which Winemaster has special knowledge, relating to matters within the scope of his employment by the Company, and the Company agrees to reimburse him for time incurred on such assistance
at the rate of $250/hour, consistent with the per diem provision in his Employment Agreement. Winemaster agrees to cooperate with the Company on all reasonable requests. Winemaster agrees that he will be responsible for any and all tax liability, if
any, arising from the payments received under this Paragraph 5. The scope and timing of such projects and assistance shall be mutually agreed upon in advance by Winemaster and the Company to the extent practicable. This provision is intended to
modify Section 8(b) of the Employment Agreement to remove the 18-month time limitation and to specify the per diem rate to be paid Winemaster. The remainder of Section 8(b) is incorporated herein by
reference and is considered part of this Agreement. Winemaster understands that nothing in this Agreement prevents or is intended to discourage him from speaking to or cooperating with the government in the ongoing investigations. 

The Company will cooperate and reasonably assist Winemaster to remove legend restrictions on Winemaster’s Company stock (PSIX) in a timely manner and as
reasonably requested by Winemaster. 
 6. Expenses. Winemaster agrees to disclose and reimburse PSI for any amounts PSI paid for airline
tickets or credits that remain unused no later than April 30, 2022. Winemaster shall submit documentation for any outstanding Business Expenses under Section 4(e) of the Employment Agreement no later than April 30, 2022. For the
avoidance of doubt, nothing in this Paragraph 6 is intended to interfere with or affect the parties’ respective rights and obligations under the Indemnification Agreement. 

7. Post-Employment Covenants Winemaster agrees that the provisions of Sections 6, 7 and 8 of his Employment Agreement remain enforceable and are
not superseded by this Agreement. For the avoidance of doubt, Section 6 (a) of Winemaster’s employment agreement (Confidential Information) does not prohibit Winemaster from providing non-privileged
information to a government agency, regulatory body or self-regulatory organization investigating a matter related to his employment with the Company, and Winemaster is not required to provide notice to the Company, or obtain approval from the
Company, prior to providing such information to the government agency, regulatory body or self-regulatory organization. Nothing in this Agreement is intended to limit or interfere with Winemaster’s ability to effectively defend himself in
connection with any investigation by a government agency, regulatory body or self-regulatory organization. 

  
 3 

 8. Confidentiality. The Company and Winemaster will keep the fact and terms of this Agreement
confidential and will not discuss or disclose these matters with or to any third person other than Winemaster’s attorneys and tax or financial advisors, except as required by law. Winemaster and the Company will advise any such person to whom
such information is disclosed that the information is confidential and may not be disclosed except as provided herein. This Section does not preclude the Company or Winemaster from disclosing this Agreement or information about this Agreement to a
court or government agency as part of a legal proceeding or investigation, provided that any such disclosure, submission, or filing is made under seal and on a confidential basis to the maximum extent allowed by law. 

9. Non-Disparagement. Except as provided in the next sentence, Winemaster and the Company hereby agree
not to make any statement at any time, in the present or future, to any person or entity which if publicized, would cause the other party humiliation or embarrassment, or would cause the public to question his integrity, competence or good
character. For the avoidance of doubt, nothing in this Agreement in any way precludes or interferes with, or is intended to preclude or interfere with Winemaster or the Company or their agents from providing testimony or information as part of a
legal proceeding or investigation or making any statements to any government enforcement or regulatory agency. 
 10. Knowing and Voluntary Waiver
of Age Claims. Winemaster acknowledges that: 
 A. He has been given a period of at least 21 days after being presented with this
Agreement in which to consider whether to sign it, and has an adequate opportunity to review this Agreement and obtain any legal advice necessary to fully understand its terms; 

B. He has read and understands this Agreement; 

C. He is waiving any and all claims against the Company under the Age Discrimination in Employment Act arising up to the date on which
he signs this Agreement; and 
 D. He has been advised that he may consult with an attorney of his choice before executing this
Agreement. 
 11. Revocation. Winemaster may revoke this Agreement within seven calendar days after signing it. The revocation will be
effective only if written notice is received by the Company before the eighth calendar day after Winemaster signs this Agreement. The Company’s obligations under this Agreement will not take effect unless the time for Winemaster to revoke this
Agreement has expired and Winemaster has not revoked the Agreement. 
 12. Notice. Any notice provided for in this Agreement must be in
writing and sent to the recipients at the address indicated below:

 or such other address or to the attention of such other person as the recipient party shall have specified by prior written
notice to the sending party. Any notice under this Agreement shall be deemed to have been duly given or made as follows: (a) if sent by registered or certified mail in the United States, return receipt requested, upon actual receipt;
(b) if sent by reputable overnight air courier (such as DHL or Federal Express), two business days after being so sent; or (c) if by electronic mail or otherwise actually personally delivered, when so delivered. 

13. Taxes and Deductions. All payments provided for in this Agreement will be subject to payroll tax withholding and deductions to the extent
required by law. Each party will report, as may be required by law for income tax purposes, its respective payment and receipt of the payments provided for in this Agreement and will bear its respective tax liabilities, if any, arising from this
Agreement. 
 14. No Admission of Wrongdoing. Nothing in this Agreement constitutes an implication or admission of wrongdoing by Winemaster or
the Company. 
 15. Section 409A. 

A. The intent of the parties is that payments and benefits under this Agreement comply with Internal Revenue Code
Section 409A and the regulations and guidance promulgated thereunder (collectively “Section 409A”) including the exceptions thereto and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in
compliance therewith, and any payments hereunder shall be made upon an event and in a manner that complies with Section 409A or an applicable exemption. Any payments under this Agreement that may be excluded from Section 409A either as
separation pay due to an involuntary separation from service or as a short-term deferral shall be excluded from Section 409A to the maximum extent possible. For purposes of Section 409A, each installment payment provided under this
Agreement shall be treated as a separate payment. Any payments to be made under this Agreement in connection with a termination of employment shall only be made if such termination of employment constitutes a “separation from service”
under Section 409A. The company shall be entitled to amend this Agreement to comply and/or clarify a payment’s compliance with Section 409A (or an exemption therefrom), provided, however, to the extent that any provision hereof is
modified, such modification shall be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and economic benefit to the Executive and the Company of the applicable provision without violating the
provisions of Section 409A. Notwithstanding anything in the Agreement to the contrary, in no event whatsoever shall the Company be liable for any tax, interest or penalty that may be imposed on Winemaster under Section 409A or any damages
for failing to comply with Section 409A. 

  
 5 

 B. Notwithstanding anything in this Agreement to the contrary, if any
payment or benefit provided to Winemaster in connection with his retirement and separation of employment is determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A and Winemaster is determined
to be a “specified employee” as defined in Section 409A(a)(2)(b)(i), then such payment or benefit shall not be paid until the first payroll date to occur following the six-month anniversary of
the Termination Date or, if earlier, on Winemaster’s death (the “Specified Employee Payment Date”). The aggregate of any payments that would otherwise have been paid before the Specified Employee Payment Date shall be paid (without
interest) to Winemaster in a lump sum on the Specified Employee Payment Date and thereafter, any remaining payments shall be paid without delay in accordance with their original schedule. 

C. To the extent required by Section 409A, each reimbursement or in-kind
benefit provided under this Agreement shall be provided in accordance with the following: (a) the amount of expenses eligible for reimbursement, or in-kind benefits provided, during each calendar year
cannot affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other calendar year; (b) any reimbursement of an eligible expense shall be paid to Winemaster on or before
the last day of the calendar year following the calendar year in which the expense was incurred; and (c) any right to reimbursements or in-kind benefits under this Agreement shall not be subject to
liquidation or exchange for another benefit. 
 16. Entire Agreement. This Agreement sets forth the entire agreement of the Parties and
supersedes all prior and contemporaneous agreements and understandings between the Parties, including but not limited to the Employment Agreement, except as otherwise explicitly stated herein. 

17. Choice of Law. This Agreement is to be construed in accordance with the laws of the State of Illinois, without regard to conflict of law
principles. 
 18. Modification of this Agreement. This Agreement may not be amended or modified except in a writing signed by the Party
against whom the amendment or modification is to be enforced. 
 19. Execution in Counterparts. This Agreement may be signed in counterparts,
which together will form the original. 
 20. Severability. Nothing in this Agreement is to be construed as waiving rights that cannot be
waived under applicable law, or as barring either Party from providing information or truthful testimony when required to do so under applicable law. Should any portion of this Agreement be ruled unenforceable by a court of competent jurisdiction,
the remainder of this Agreement and the releases and covenant not to sue contained herein will remain in full force and effect as to any and all other claims.
