		8.	Upon the original issuance of the Securities, until such time as it is no longer required under
applicable requirements of the U.S. Securities Act or applicable state securities laws, the certificates representing the Securities
(and any certificates issued in exchange or substitution for the Securities) will bear a legend, in addition to the legends set
out in the Subscription Agreement, in substantially the form as follows:



 


“THE SECURITIES REPRESENTED
HEREBY [for Warrants, include: AND THE SECURITIES ISSUABLE UPON EXERCISE HEREOF] HAVE NOT BEEN REGISTERED UNDER THE
UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “U.S. SECURITIES ACT”) OR ANY STATE SECURITIES LAWS. THE HOLDER
HEREOF, BY PURCHASING OR OTHERWISE HOLDING SUCH SECURITIES, AGREES FOR THE BENEFIT OF CANADIAN ZINC CORPORATION (THE “COMPANY”)
THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY (A) TO THE COMPANY, (B) OUTSIDE THE UNITED STATES
IN ACCORDANCE WITH REGULATION S UNDER THE U.S. SECURITIES ACT, (C) PURSUANT TO THE EXEMPTION FROM REGISTRATION UNDER THE U.S. SECURITIES
ACT PROVIDED BY (I) RULE 144 OR (II) RULE 144A THEREUNDER, IF AVAILABLE, AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS
OF THE UNITED STATES, OR (D) IN ANOTHER TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE U.S. SECURITIES ACT OR ANY APPLICABLE
STATE SECURITIES LAWS OF THE UNITED STATES, AFTER THE HOLDER HAS, IN THE CASE OF (C)(I) OR (D) ABOVE, FURNISHED TO THE COMPANY
AN OPINION OF COUNSEL OR OTHER EVIDENCE OF EXEMPTION, IN EITHER CASE REASONABLY SATISFACTORY TO THE COMPANY. DELIVERY OF THIS CERTIFICATE
MAY NOT CONSTITUTE “GOOD DELIVERY” IN SETTLEMENT OF TRANSACTIONS ON STOCK EXCHANGES IN CANADA.”


 


If Investor is eligible to transfer
the Securities outside the United States in accordance with Rule 904 of Regulation S, a new certificate, which will constitute
“good delivery” in settlement of transactions on Canadian stock exchanges, will be made available to the Investor upon
provision by the Investor of a declaration in the form attached as Appendix A or in such other form that is acceptable to the Company,
together with any other evidence, which may include a legal opinion reasonably satisfactory in form and substance to the Company,
required by the Company or the registrar and transfer agent for the Securities.


 


If any of the Securities are
being sold pursuant to Rule 144 under the U.S. Securities Act, the legend may be removed by delivery to the registrar and transfer
agent of an opinion of counsel of recognized standing in form and substance satisfactory to the Company, to the effect that the
legend is no longer required under applicable requirements of the U.S. Securities Act or state securities laws.


 


The Company agrees to take such
actions and execute such documents as may be reasonably requested by the Investor or the Company’s transfer agent to promptly
remove any legends in accordance with applicable law restricting transferability of the Common Shares placed on share certificates
issued in relation to the Offering (if any), subject to and in compliance with applicable securities laws (including U.S. and Canadian
securities laws). If a legal opinion is required by the Company’s transfer agent for legend removal, the Investor may request
that the Company provide such opinion or the Investor may elect to obtain the opinion from counsel of its choosing, reasonably
acceptable to the Company, and, in either event, the Company shall pay the reasonable cost of issuing such opinion on the Investor’s
behalf, the Investor shall provide such supporting documentation for such legal opinion as may be reasonably requested by counsel.


 




    		- 3 -	 



     


    

 


		9.	It understands and acknowledges that the Company is not obligated to file and has no present intention
of filing with the U.S. Securities and Exchange Commission (the “SEC”) or with any state securities administrator
any registration statement in respect of resales of the Securities in the United States.



 


		10.	It understands and agrees that there may be material tax consequences to the Investor of an acquisition,
holding or disposition of the Securities. The Company gives no opinion and makes no representation with respect to the tax consequences
to the Investor under United States, state, local or foreign tax law of the undersigned’s acquisition, holding or disposition
of such Securities and the Investor acknowledges that it is solely responsible for determining the tax consequences of its investment.
In particular, no determination has been made whether the Company is, or will be, a “passive foreign investment company”
within the meaning of Section 1297 of the United States Internal Revenue Code of 1986, as amended.



 


		11.	It understands and agrees that the financial statements of the Company have been prepared in accordance
with Canadian IFRS, which differ in some respects from United States generally accepted accounting principles, and thus may not
be comparable to financial statements of United States companies.



 


		12.	It consents to the Company making a notation on its records or giving instructions to any transfer
agent for the Securities in order to implement the restrictions on transfer set forth and described in this Schedule A.



 


		13.	It understands that the Securities are “restricted securities” within the meaning of
Rule 144 under the U.S. Securities Act and that the U.S. Securities Act and the rules of the SEC provide that the Investor may
dispose of the Securities only pursuant to an effective registration statement under the U.S. Securities Act or an exemption or
exclusion from registration under the U.S. Securities Act, and the Investor understands that the Company has no obligation to register
any of the Securities or to take action so as to permit sales pursuant to the U.S. Securities Act (including Rule 144 thereunder)
or state securities laws. Accordingly, the Investor understands that absent registration, under the rules of the SEC, or a valid
exemption therefrom, the Investor may be required to hold the Securities indefinitely. As a consequence, the Investor understands
that it must be able to bear the economic risks of the investment in the Securities for an indefinite period of time.



 


		14.	It understands and acknowledges that the Company (i) is not obligated to remain a “foreign
issuer” (as defined in Regulation S under the U.S. Securities Act; (ii) may not, at the time the Securities are resold by
it or at any other time, be a foreign issuer, and (iii) may engage in one or more transactions that could cause the Company not
to be a foreign issuer.



 


		15.	It understands that (i) the Company may be deemed to be an issuer that has been at any time previously,
or may in the future be deemed to be, an issuer with no or nominal operations and no or nominal assets other than cash and cash
equivalents (a “Shell Company”), (ii) if the Company is at any time deemed to be, or to have been at any time
previously, a Shell Company, Rule 144 under the 1933 Act may not be available for resales of the Securities, and (iii) the Company
is not obligated to make Rule 144 under the 1933 Act available for resales of the Securities;



 


		16.	It understands and agrees that the certificates representing the Warrants, and all certificates
issued in exchange therefor or in substitution thereof, shall bear the following legend:



 




    		- 4 -	 



     


    

 


“THIS WARRANT AND THE SECURITIES
DELIVERABLE UPON EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “1933
ACT”), OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES. THIS WARRANT MAY NOT BE EXERCISED BY OR ON BEHALF OF A U.S.
PERSON OR PERSON IN THE UNITED STATES UNLESS THIS WARRANT AND SECURITIES ISSUABLE UPON EXERCISE OF THIS WARRANT HAVE BEEN REGISTERED
UNDER THE 1933 ACT AND THE APPLICABLE SECURITIES LEGISLATION OF ANY SUCH STATE OR AN EXEMPTION FROM SUCH REGISTRATION REQUIREMENTS
IS AVAILABLE. “UNITED STATES” AND “U.S. PERSON” ARE AS DEFINED BY REGULATION S UNDER THE 1933 ACT.”;


 


		17.	it understands and agrees that the Warrants may not be exercised by or on behalf of a “U.S.
person” (as that term is defined under Rule 902(k) of Regulation S under the U.S. Securities Act) or a person in the United
States unless an exemption is available from the registration requirements of the 1933 Act and the securities laws of all applicable
states, and the holder has furnished an opinion of counsel satisfactory to the Company to such effect; provided, however, that
the Investor will not be required to furnish an opinion of counsel in connection with its exercise of the Warrants solely for its
own account, at a time when it remains an institutional “accredited investor” that meets the requirements set forth
in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the U.S. Securities Act;



 


		18.	Upon execution of this Schedule A by the undersigned Investor, this Schedule A and Appendix A hereto
shall be incorporated into and form a part of the Subscription Agreement to which this Schedule is attached.

WARRANTS TO PURCHASE COMMON SHARES OF


 


CANADIAN
ZINC CORPORATION


 


Certificate No: [●]


	Dated: [●], 2018	50,000,000 Warrants


 


THIS CERTIFIES that, for value received,
RCF VI CAD LLC (the “Holder”), is the registered holder of 50,000,000 warrants (the “Warrants”)
which entitle the Holder, subject to the terms and conditions set forth in this warrant certificate (this “Certificate”),
to purchase from Canadian Zinc Corporation (the “Company”), up to 50,000,000 common shares of the Company (the
“Shares”) at any time commencing on the date hereof and continuing up to 5:00 p.m. (Vancouver time) on December
31, 2018 (the “Time of Expiry”), on payment of the exercise price per Share of CDN$0.25 (the “Exercise
Price”). The number of Shares which the Holder is entitled to acquire upon exercise of the Warrants and the Exercise
Price are subject to adjustment as hereinafter provided.


 




     


     


    

 


		1.	Exercise of Warrants.



 


		1.1.	Election to Purchase. The Warrants evidenced by this Certificate may be exercised
by the Holder in whole or in part, subject to the above, and in accordance with the provisions hereof by delivery of an election
to purchase in substantially the form attached hereto as Schedule “A” (the “Election to Purchase”),
properly completed and executed, together with payment of the Exercise Price by certified cheque, bank draft or money order payable
to the order of the Company for the number of Shares specified in the Election to Purchase at the principal office of the Company
or such other address in Canada as may be notified in writing by the Company. In the event that the rights evidenced by this Certificate
are exercised in part, the Company shall, upon delivery of this Certificate for cancellation, contemporaneously with the issuance
of the Shares issuable on the exercise of the Warrants so exercised, issue to the Holder a certificate on identical terms as this
Certificate in respect of that number of Warrants in respect of which the Holder has not exercised the rights evidenced by this
Certificate.



 


		1.2.	Exercise. The Company shall, on the date it receives a duly executed Election to
Purchase and the Exercise Price for the number of Shares specified in the Election to Purchase (the “Exercise Date”),
issue that number of Shares specified in the Election to Purchase as fully paid and non-assessable common shares in the capital
of the Company.



 


		1.3.	Certificates. As promptly as practicable after the Exercise Date and, in any event,
within three (3) business days (for purposes hereof, business day means any day that the banks in Vancouver, British Columbia are
open for business) of receipt of the Election to Purchase and the Exercise Price for the number of Shares specified in the Election
to Purchase, the Company shall issue and deliver to the Holder, registered in such name or names as the Holder may direct or if
no such direction has been given, in the name of the Holder, a certificate or certificates for the number of Shares specified in
the Election to Purchase. To the extent permitted by law, such exercise shall be deemed to have been effected as of the close of
business on the Exercise Date, and at such time the rights of the Holder with respect to the number of Warrants which have been
exercised as such shall cease, and the person or persons in whose name or names any certificate or certificates for Shares shall
then be issuable upon such exercise shall be deemed to have become the holder or holders of record of the Shares represented thereby.



 


		1.4.	Legending. All certificates issued in exchange for or in substitution of this Certificate
and all certificates issued upon the exercise of the Warrants evidencing the Shares (and any certificates issued in exchange or
in substitution thereof) shall bear the following legends, unless such exchange, substitution or issuance occurs subsequent to
[Insert date that is four months and a day from the closing date]:



 


“UNLESS PERMITTED UNDER SECURITIES
LEGISLATION, THE HOLDER OF THE SECURITY MUST NOT TRADE THE SECURITY BEFORE [Insert date that is four months and a day from the
closing date].”


 


and if required,


 


WITHOUT PRIOR WRITTEN APPROVAL
OF THE TORONTO STOCK EXCHANGE AND COMPLIANCE WITH ALL APPLICABLE SECURITIES LEGISLATION, THE SECURITIES REPRESENTED BY THIS CERTIFICATE
MAY NOT BE SOLD, TRANSFERRED, HYPOTHECATED OR OTHERWISE TRADED ON OR THROUGH THE FACILITIES OF THE TORONTO STOCK EXCHANGE OR OTHERWISE
IN CANADA OR TO OR FOR THE BENEFIT OF A CANADIAN RESIDENT UNTIL [Insert date that is four months and a day from the closing
date].


 




    	 	2	 



     


    

 


The Warrants and the Shares issuable
upon exercise hereof have not been registered under the United States Securities Act of 1933, as amended (the “U.S.
Securities Act”), or the securities laws of any state of the United States. Accordingly, the Warrants and the Shares
issuable upon exercise hereof may not be offered or sold, directly or indirectly, in the United States, or to or for the account
or benefit of a U.S. person or a person in the United States, except pursuant to registration under the U.S. Securities Act and
the applicable securities laws of all applicable states or available exemptions therefrom. The Warrants may not be exercised by
or on behalf of a U.S. person or person in the United States unless the Warrants and the Shares issuable upon exercise of the Warrants
have been registered under the U.S. Securities Act and the applicable securities legislation of any such state or an exemption
from such registration requirements is available. “United States” and “U.S. person” are as defined by Regulation
S under the U.S. Securities Act (“Regulation S”). The Holder hereby agrees and consents by acceptance hereof
that all certificates representing Shares acquired upon exercise of the Warrants by, or for the account or benefit of, U.S. persons
or persons in the United States shall have the following legend:


 


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


 


provided, that if the Shares are being
sold under clause (B) above and the Company continues to qualify as a “foreign issuer” within the meaning of Regulation
S at the time of issuance of such Shares, the legend set forth above may be removed by providing a declaration to the Company and
its registrar and transfer agent in the form attached hereto as Schedule “B” or such other evidence of exemption as
the Company or its registrar and transfer agent may from time to time prescribe (which may include an opinion satisfactory to the
Company and its registrar and transfer agent (the Company shall bear the costs of such legal opinion)), to the effect that the
sale of the Shares is being made in compliance with Rule 904 of Regulation S under the U.S. Securities Act; provided further, that
if any of the Shares are being sold pursuant to Rule 144 of the U.S. Securities Act, if available, and in compliance with any applicable
state securities laws, the legend may be removed by delivery to the Company’s registrar and transfer agent of an opinion
satisfactory to the Company and its registrar and transfer agent to the effect that the legend is no longer required under applicable
requirements of the U.S. Securities Act or state securities laws. The Company shall bear the costs of such legal opinion.


 


		1.5.	Not
a Shareholder. Nothing contained in this Certificate shall be construed as conferring upon the Holder any right or interest
whatsoever as a holder of common shares of the Company or any other right or interest except as herein expressly provided.



 




    	 	3	 



     


    

 


	 	1.6.	Fractional Shares or Warrants. No fractional Shares shall be issued upon exercise of any Warrants and no payments or adjustment shall be made upon any exercise on account of any cash dividends on the Shares issued upon such exercise. If any fractional interest in a Share would, except for the provisions of the first sentence of this Section 1.6, be deliverable upon the exercise of Warrants, the Company shall, in lieu of delivering the fractional Share therefor, pay to the Holder an amount in cash equal to the Exercise Price multiplied by such fractional interest.


 


	 	1.7.	Shares to be Reserved. The Company will at all times keep available, and reserve if necessary under British Columbia law, out of its authorized common shares, solely for the purpose of issue upon the exercise of the Warrants, such number of Shares as are then issuable upon the exercise of the Warrants. The Company covenants and agrees that all Shares which shall be so issuable will, upon issuance, be duly authorized and issued as fully paid and non-assessable. The Company will take all such actions as may be necessary to ensure that all such Shares may be so issued without violation of any applicable requirements of any exchange upon which the common shares of the Company may be listed or in respect of which the common shares of the Company are qualified for unlisted trading privileges. The Company will take all such actions that are within its power to ensure that all such Shares may be so issued without violation of any applicable law.


 


	 	1.8.	Issue Tax. The issuance of certificates for Shares upon the exercise of Warrants shall be made without charge to the Holder for any issuance tax in respect thereto, provided that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than that of the Holder.


 


		2.	Certain
Adjustments. The Exercise Price and number of Shares issuable upon exercise of this Certificate are subject to adjustment
from time to time as set forth in this Section 2.


 


		2.1.	Offering
to Shareholders. If and whenever at any time after the date hereof the Company fixes a record date for the issue of rights,
options or warrants to the holders of all or substantially all of its outstanding common shares under which such holders are entitled
to subscribe for or purchase common shares or securities exchangeable for or convertible into common shares where:


 


		(i)	the
right to subscribe for or purchase common shares, or the right to exchange securities for or convert securities into common shares,
expires not more than 45 days after the date of such issue (the period from the record date to the date of expiry being herein
in this Section 2.1 called the “Rights Period”); and


 


	 	(ii)	the cost per common share during the Rights Period (inclusive of any cost of acquisition of securities exchangeable for or convertible into common shares in addition to any direct cost of Shares) (for the purposes of this Section 2.1 called the “Per Share Cost”) is less than 95% of the Current Market Price (as defined below) of the common shares on the record date,


 


(any of such events being called a
“Rights Offering”), then the Exercise Price will be adjusted effective immediately after the end of the Rights
Period to a price determined by multiplying the Exercise Price in effect immediately prior to the end of the Rights Period by a
fraction:


 


		(A)	the numerator of which is the aggregate of:



 


		(a)	the number of common shares outstanding as of the record
date for the Rights Offering; and



 


		(b)	a number determined by dividing the product of the Per
Share Cost and:



 


		(i)	where the event giving rise to the application of this
section 2.1 was the issue of rights, options or warrants to the holders of common shares under which such holders are entitled
to subscribe for or purchase additional common shares, the number of common shares so subscribed for or purchased during the Rights
Period, or



 






    	 	4	 



     


    

 


		(ii)	where the event giving rise to the application of this
section 2.1 was the issue of rights, options or warrants to the holders of common shares under which such holders are entitled
to subscribe for or purchase securities exchangeable for or convertible into common shares, the number of common shares for which
those securities so subscribed for or purchased during the Rights Period could have been exchanged or into which they could have
been converted during the Rights Period,



 


by the price per share equal to the
weighted average price at which the common shares of the Company have traded in board lots on the Toronto Stock Exchange (“TSX”)
or, if the common shares of the Company are not then listed on the TSX, on such stock exchange on which such shares are listed
as may be selected by action of the directors of the Company for such purpose or, if not listed on any stock exchange, in the over-the-counter
market, during a period of 30 consecutive trading days commencing not more than 45 trading days before such date and ending not
less than three trading days before the applicable record date (the “Current Market Price”) as of the record
date for the Rights Offering; and


 


		(B)	the denominator of which is:



 


	 	(a)	in the case described in subparagraph 2.1(A)(b)(i), the number of common shares outstanding, or


 


	 	(b)	in the case described in subparagraph 2.1(A)(b)(ii), the number of common shares that would be outstanding if all the common shares described in subparagraph 2.1(A)(b)(ii) had been issued,


 


as at the end of the Rights Period.


 


Such adjustments shall be made successively
whenever such a record date is fixed; to the extent that any rights or warrants are not so issued or any such rights or warrants
are not exercised prior to the expiration thereof, the Exercise Price shall then be readjusted to the Exercise Price which would
then be in effect if such record date had not been fixed or to the Exercise Price which would then be in effect based upon the
number of common shares or conversion or exchange rights contained in convertible or exchangeable securities actually issued upon
exercise of such rights or warrants, as in case may be.


 


		2.2.	Special
Distributions. If and whenever at any time prior to the Time of Expiry, the Company fixes a record date for the distribution
to all or substantially all the holders of its common shares of:


 


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



 


		(ii)	rights, options or warrants;





 


		(iii)	evidence of indebtedness; or



 


		(iv)	other assets or property;



 






    	 	5	 



     


    

 


and if such distribution does
not constitute a Rights Offering or does not consist of rights, options or warrants entitling the holders of common shares of
the Company to subscribe for or purchase common shares of the Company, Participating Shares or Convertible Securities (as
defined below) for a period expiring not more than 45 days after such record date and at a price per share (or having a
conversion or exchange price per share) of at least 95% of the Current Market Price on such record date (any such
non-excluded event being hereinafter referred to as a “Special Distribution”), the Exercise Price will be
adjusted effective 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, the numerator of which is the volume weighted average trading price for a
five-day period commencing on the “ex-distribution” date, and the denominator of which is the volume weighted
average trading price for a five-day period ending immediately prior to the “ex-distribution” date.


 


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


 


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


 


		2.3.	Subdivision or Consolidation of Shares.



 


		(i)	In
the event the Company shall, prior to the Time of Expiry, subdivide its outstanding common shares of the Company into a greater
number of shares (either directly or by way of stock dividend or other distribution of the common shares of the Company payable
in common shares of the Company, Participating Shares (as hereinafter defined) or Convertible Securities (as hereinafter defined)),
the Exercise Price in effect immediately prior to such subdivision shall on the effective date in the case of a subdivision or
on the record date in the case of a stock dividend be proportionately reduced as of the effective date of such event, and conversely,
in case the outstanding common shares of the Company are consolidated into a smaller number of shares, the Exercise Price in effect
immediately prior to such consolidation shall be proportionately increased as of the effective date of such event. Any proportionate
adjustment in the Exercise Price shall consider the number of outstanding common shares of the Company and outstanding Participating
Shares. The number of outstanding common shares of the Company and outstanding Participating Shares shall include the deemed conversion
into or exchange for common shares of the Company or Participating Shares or Convertible Securities distributed by way of stock
dividend or other such distribution.


 


	 	(ii)	Upon each adjustment of the Exercise Price as provided in this section 2.3, the Holder shall thereafter be entitled to acquire, at the Exercise Price resulting from such adjustment, the number of Shares (calculated to the nearest tenth of a Share) obtained by multiplying the Exercise Price in effect immediately prior to such adjustment by the number of Shares which may be acquired hereunder immediately prior to such adjustment and dividing the product thereof by the Exercise Price resulting from such adjustment.


 


		2.4.	Change
or Reclassification of Shares.       In the event the Company changes or reclassifies
its outstanding common shares of the Company into a different class of securities, the rights evidenced by the Warrants shall
be adjusted as of the effective date of such event as follows so as to apply to the successor class of securities:


 


		(i)	the
number of the successor class of securities which the Holder shall be entitled to acquire shall be that number of the successor
class of securities which a holder of that number of Shares subject to the unexercised Warrants immediately prior to the change
or reclassification would have been entitled to by reason of such change or reclassification; and


 




    	 	6	 



     


    

 


	 	(ii)	the Exercise Price shall be determined by multiplying the Exercise Price in effect immediately prior to the change or reclassification by the number of Shares subject to the unexercised Warrants immediately prior to the change or reclassification, and dividing the product thereof by the number of shares determined in section 2.4(i) hereof.


 


If necessary, appropriate adjustments
shall be made in the application of the provisions set forth in this section 2 with respect to the rights and interests thereafter
of the Holder of the Warrants to the end that the provisions set forth in this Section 2 shall thereafter correspondingly be made
applicable as nearly as may be reasonable in relation to any shares or other securities or property thereafter deliverable upon
the exercise of the Warrants.


 


	 	2.5.	Pro Rata Distributions. If the Company, at any time while the Warrants are outstanding, distributes to holders of common shares (i) evidences of its indebtedness, (ii) any security (other than a distribution of common shares covered by Section 2.2), (iii) rights or warrants to subscribe for or purchase any security, or (iv) any other asset (in each case, “Distributed Property”), then upon any exercise of the Warrants that occurs after the record date fixed for determination of stockholders entitled to receive such distribution, the Holder shall be entitled to receive, in addition to the Shares otherwise issuable upon such exercise (if applicable), the Distributed Property that the Holder would have been entitled to receive in respect of such number of Shares had the Holder been the recorded holder of such Shares immediately prior to such record date. The provisions of this Section 2.5 shall not apply to dividends paid in any financial year of the Company, whether in (i) cash, (ii) shares of the Company, (iii) warrants or similar rights to purchase any shares of the Company or property or other assets of the Company provided that the value of such dividends does not in such financial year exceed the greater of: (i) 150% of the aggregate amount of dividends paid by the Company on the Shares in the 12-month period ending immediately prior to the first day of such financial year, and (ii) 100% of the consolidated net earnings from continuing operations of the Company, before any extraordinary items, for the 12-month period ending immediately prior to the first day of such financial year (such consolidated net earnings from continuing operations to be computed in accordance with generally accepted accounting principles in Canada).


 


	 	2.6.	Participating Shares and Convertible Securities. For the purpose of this Section 2: (i) “Participating Share” means a share (other than a common share of the Company) that carries the right to participate in earnings to an unlimited degree; (ii) “Convertible Security” means a security convertible into or exchangeable for a common share of the Company or a Participating Share or both; and (iii) “Person” means an individual, corporation, partnership, limited liability company, trust, business trust, association, joint stock company, joint venture, sole proprietorship, unincorporated organization, governmental authority or any other form of entity not specifically listed herein.


 


	 	2.7.	Notice of Adjustment. Upon any adjustment of the number of Shares and upon any adjustment of the Exercise Price (collectively, an “Adjustment”), then and in each such case, forthwith but no later than fourteen (14) days thereafter, the Company shall give written notice thereof to the Holder, which notice shall state the Exercise Price and the number of Shares subject to the Warrants resulting from such Adjustment, and shall set forth in reasonable detail the method of calculation and the facts upon which such calculation is based. In the event of any disputes, disagreements, controversies or questions arising from or related to the Adjustment (in each case, a “Dispute”) the Company will endeavour to settle such Dispute to the satisfaction of the Company and the Holder, both acting reasonably. Any Dispute that is not settled to the satisfaction of the Company and the Holder, both acting reasonably, will be conclusively determined by a firm of independent chartered accountants (who may be the Company's auditors) and shall be binding upon the Company and the Holder. The Company hereby covenants to give any such firm of independent chartered accountants access to all necessary records of the Company. Failure of the taking of action by the directors of the Company so as to provide for an adjustment on or prior to the effective date of any action by the Company affecting the Shares will be conclusive evidence that the board of directors of the Company has determined that it is equitable to make no adjustment in the circumstances.


 




    	 	7	 



     


    

 


	 	2.8.	No Adjustment. No adjustment in the Exercise Price or in the number of Shares shall be required unless such adjustment would result in a change of at least 1% in the Exercise Price then in effect or unless the number of Shares to be issued would change by at least 1/100th of a Share, provided, however, that any adjustments, which, except for the provisions of this Section 2.8 would otherwise have been required to be made, shall be carried forward and taken into account in any subsequent adjustment.


 


		3.	General Covenants of the Company



 


	 	3.1.	The Company covenants with the Holder that so long as any Warrants remain outstanding: 


 


		(a)	it is duly authorized to enter into and perform its obligations
under this Certificate;



 


		(b)	all things necessary have been done and performed to create
the Warrants and to make the Warrants and this Certificate legal, valid and binding upon the Company with the benefits and subject

		4.	Participation by the Investor in Equity Financing



 


Subject to compliance with Applicable
Law, including, if required, the approval of the Exchange, from and after the date of this Agreement and for so long as the Investor’s
Percentage is at least 10%, the Investor shall have the following rights in respect of any Equity Financing:


 




    	 	- 3 -	 



     


    

 


		(a)	the
right, but not the obligation, to participate, in such Equity Financing up to the extent required to allow the Investor to maintain
the same Investor’s Percentage that it possessed immediately prior to the announcement of such Equity Financing such that,
if fully exercised, the Investor does not suffer any equity dilution (the “Participation Right”); and


 


	 	(b)	the right, but not the obligation, to subscribe for any Equity Securities issued in connection with such Equity Financing not taken up by other investors or subscribers to enable the Investor to increase its equity ownership percentage in the Company (the “Top-up Right”).


 


If the Company intends or proposes to, or enters into documentation
purporting to issue or authorize an Equity Financing, then in each case:


 


		(i)	Notice of Financing: the Company shall first provide
written notice of such Equity Financing to the Investor, as soon as possible, but in any event on or prior to the earlier of 10
Business Days prior to the expected completion date of such Equity Financing, and the date on which the Company files a preliminary
prospectus or other offering document in connection with such Equity Financing, including a detailed summary of the material terms
and conditions of such Equity Financing, together with any other information that the Investor may thereafter reasonably request
in respect of the same;



 


		(ii)	Election Right of Investor: if the Investor wishes to exercise its Participation Right or
Top-up Right, as the case may be, the Investor must provide the Company with written notice that it is exercising its Participation
Right or its Top-up Right, as the case may be, before the earlier of (A) five (5) Business Days after the date of receipt by the
Investor of notice of such Equity Financing from the Company pursuant to paragraph (i) above, and (B) 48 hours after public announcement
of such Equity Financing if such Equity Financing is a “bought deal” public offering (or 24 hours in the event that
the Investor elects to exercise its Top-up Right and such exercise would require shareholder approval under Applicable Law); failing
which, the Investor shall be deemed to have elected not to exercise its rights under this paragraph 4;



 


		(iii)	Flow-Through Shares: to the extent that such Equity Financing involves the issuance of common
shares in the Company that will be issued as “flow-through shares” (as defined in subsection 66(15) of the Income
Tax Act (Canada)), at a price per share that reflects a premium associated with a flow-through designation, and the Investor
elects to participate in such offering, the Company agrees to negotiate in good faith the price at which such flow-through shares
will be issued to the Investor, taking into consideration that any benefits received by a purchaser of flow-through shares will
not be received by the Investor;



 


		(iv)	Completion of Equity Financing: if the Investor notifies the Company of its election to
exercise its Participation Right or Top-up Right pursuant to paragraph (ii) above, the Company shall use all commercially reasonable
efforts, including, but not limited to, promptly making all required filings with the Exchange or any other applicable securities
regulator, commission or authority and paying all fees in connection therewith, to obtain any Exchange or regulatory approvals
required in respect of the issuance of Equity Securities to the Investor in respect of such Equity Financing and, subject to Applicable
Law, the Company and the Investor shall proceed to complete the purchase and sale of the Equity Securities that are the subject
of such Equity Financing, which completion may take place concurrently with and subject to the closing of the issuance of other
Equity Securities forming part of the same Equity Financing, provided that the issue price offered to the Investor shall, subject
to Applicable Law, be equivalent to the issue price under the Equity Financing. In the case of an Equity Financing that is a “bought
deal” public offering, the Equity Securities that the Investor elects to purchase shall be issued to the Investor by the
Company in a concurrent private placement with the Investor on the same terms as such wider Equity Financing, subject to Applicable
Law;



 




    	 	- 4 -	 



     


    

 


	 	(v)	Prospectus Offering: without limitation to any of the rights of the Investors under paragraphs (i) to (iv) above, the Company shall use commercially reasonable efforts to include the Investor’s pro rata entitlement in any such Equity Financing that is a prospectus offering, provided that if the Investor’s pro rata share is not included in such prospectus offering, the Company shall ensure that the Investor is provided with the opportunity to subscribe for such Equity Securities on a private placement basis as soon as reasonably possible thereafter, and in no case later than fifteen (15) Business Days after the closing of the prospectus offering on terms no less favourable as those provided to investors under such Equity Financing. Notwithstanding the foregoing, any Equity Securities subscribed for by the Investor in the case of a public offering that is a “bought deal” shall be issued on a private placement basis on terms no less favourable as those provided to investors under such Equity Financing;


 


		(vi)	Shareholder Approval: if the Company is required by the Exchange or otherwise to seek shareholder
approval for the issuance of Equity Securities to the Investor under such Equity Financing, then the Company may complete that
portion of such Equity Financing that the Exchange will then permit without shareholder approval, provided that the Investor subscribes
for and is issued at that time the lesser of:



 


		(A)	a
pro rata portion of the maximum number of Equity Securities that the Investor wishes to purchase as part of such Equity Financing
based on the size of the issuance that the Company is entitled to complete without obtaining shareholder approval; and


 


	 	(B)	the maximum number of Equity Securities that the Exchange will permit the Company to issue to the Investor as part of such Equity Financing without obtaining shareholder approval,


 


and the Company shall call and hold
a meeting of its shareholders to consider the subscription and issuance of the balance of the Equity Securities in such Equity
Financing as soon as reasonably practicable and in any event within sixty (60) days after the date that the Company is advised
that it will require shareholder approval. In connection with such meeting of shareholders (or any adjournment or postponement
thereof), unless inconsistent with the fiduciary duties of the Board, management of the Company shall recommend in writing that
shareholders vote in favour of such equity issuance to the Investor and shall vote their common shares in the Company in respect
of which management is granted a discretionary proxy in favour of such equity issuance to the Investor. If shareholder approval
for such issuance is obtained, the Company will issue to the Investor the remaining Equity Securities in such Equity Financing
on the Business Day following receipt of such shareholder approval. If, however, shareholder approval for the issuance of Equity
Securities in such Equity Financing is not obtained at such meeting, the Company shall not issue any such Equity Securities to
the Investor; and


 


		(vii)	Continuing Right of the Company: if the Investor elects or is deemed to have elected not
to exercise its Participation Right or Top-up Right in respect of such Equity Financing then the Company may, at any time within
forty-five (45) days of such election (or deemed election), complete such Equity Financing on substantially
the same terms and conditions as initially indicated to the Investor by the Company.



 




    	 	- 5 -	 



     


    

 


For greater certainty and notwithstanding
anything to the contrary contained in this Agreement, the participation rights of the Investor under this paragraph 4 or otherwise
will not apply to the issuance by the Company of Equity Securities (A) pursuant to the Company’s stock option plan or other
compensation plans for employees, consultants, officers or directors of the Company and its Affiliates (including the issuance
of options, restricted stock, restricted share units, restricted stock units, performance share units, deferred share units and
any securities issued on exercise, vesting or settlement thereof), (B) in respect of securities issued or made issuable in connection
with bona fide acquisitions by the Company, (C) the conversion or exchange of any Equity Securities of the Company into common
shares of the Company, or the exercise of any warrants or other rights to acquire common shares of the Company, or (D) in respect
of securities issued or made issuable pursuant to or in connection with a rights offering or similar transaction.


 


		5.	Participation by the Investor in Debt or Royalty Financing



 


If, at any time while the Investor’s
Percentage is at least 10%, the Company intends or proposes to issue any convertible debt securities, or enters into documentation

a “Debt or Royalty Financing”), then in each case:


 


	 	(a)	Notice of Financing: the Company shall promptly provide written notice of such Debt or Royalty Financing, as the case may be, to the Investor, including a detailed summary of the material terms and conditions of such Debt or Royalty Financing, together with any other information that the Investor may thereafter reasonably request in respect of the same;

	 	(c)	Continuing Right of the Company: if the Investor does not elect (or is deemed to have not elected) to exercise its right of participation pursuant to paragraph (b) above then the Company may, at any time within sixty (60) days of such election (or such deemed election at the end of the above twenty (20) Business Day period), take steps to complete such Debt or Royalty Financing on substantially the same terms and conditions as initially indicated to the Investor.
