the terms and conditions hereof by the Corporation. By written order of the Corporation, made from time to time on or after the Issue Date, the Warrant Agent shall deliver Warrant Certificates to Registered Warrantholders and record the name of the
Registered Warrantholders on the register for Warrants of the Warrant Agent. 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 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) Common 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 Common Shares.

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

meetings of Shareholders or any other proceedings of the Corporation, or the right to Dividends and other allocations.

of this Indenture, which shall be dated as of the Issue Date, shall bear such legends and distinguishing letters and numbers as the Corporation may, with the approval of the Warrant Agent, prescribe, and shall be issuable in any denomination
excluding fractions. All Warrants issued to the Depository may be in either a certificated or uncertificated form, such uncertificated form being evidenced by a book position on the register of Warrantholders to be maintained by the Warrant Agent in
accordance with Section 2.6. 
 Section 2.6 Book Entry Warrants. 
  

	(1)	Registration 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

Section 2.6, owners of beneficial interests in any Global Warrants shall not be entitled to have Warrants registered in their names and shall not receive or be entitled to receive Warrants in definitive form or to have their names appear in the
register referred to in Section 2.9 herein. Notwithstanding any terms set out herein, Warrants held in the name of the Depository may only be held in the form of Uncertificated Warrants with the prior consent of the Warrant Agent and in

	(2)	Notwithstanding any other provision in this Indenture, no Global Warrants may be exchanged in whole or in part for Warrants registered, and no transfer of Global Warrants in whole or in part may be registered, in the
name of any person other than the Depository for such Global Warrants or a nominee thereof unless:

	 	(b)	the Corporation determines that the Depository is no longer willing, able or qualified to discharge properly its responsibilities as holder of the Global Warrants and the Corporation is unable to locate a qualified
successor; 

  

	 	(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 Law, as determined by the Corporation and the Corporation’s counsel; or 

  

	 	(f)	such registration is effected in accordance with the internal procedures of the Depository and the Warrant Agent, 

following which, Warrants for those holders requesting such shall be issued to the beneficial owners of such Warrants or their nominees as
directed by the holder. The Corporation shall provide a certificate executed by an officer of the Corporation giving notice to the Warrant Agent of the occurrence of any event outlined in this Section 2.6(2). 

  
 7 

	(3)	Subject to the provisions of this Section 2.6, any exchange of Global Warrants for Warrants which are not 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 Global Warrant or any portion thereof shall be registered in such names as the Depository for such Global Warrants shall direct and shall be entitled to the same benefits and subject to
the same terms and conditions (except insofar as they relate specifically to Global Warrants) as the Global Warrants or portion thereof surrendered upon such exchange. 

 

	(4)	Every Warrant Authenticated upon registration of transfer of a Global Warrant, or in exchange for or in lieu of a 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 Global Warrant, unless such Warrant is registered in the name of a person other than the Depository for such Global Warrant or a nominee thereof. 

 

	(5)	Notwithstanding anything to the contrary in this Indenture, subject to Applicable Law, the Global Warrant will be issued as a Certificated 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 Law 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, the Corporation, the Underwriters, the Warrant Agent, and their respective agents shall not have any responsibility or liability for: 

 

	 	(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 nominee); 

 

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

  

	 	(c)	any advice or representation made or given by the Depository or those contained herein that relate to the rules and regulations of the Depository or any action to be taken by the Depository on its own direction or at
the direction of any Book Entry Participant. 

  

	(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 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 an authorized officer 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. Any Warrant Certificate which has the applicable signature
as hereinbefore provided shall be valid notwithstanding that such person whose signature is printed, lithographed or mechanically reproduced no longer holds office at the date of issuance of such certificate. The Warrant Certificates may be
engraved, printed or lithographed, or partly in one form and partly in another, as the Warrant Agent may determine. 

  
 8 

	(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 Law, validly
entitle the holder to acquire Common 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, 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, 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. 

 

	(5)	No Certificated Warrant 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 Certificated Warrant shall be conclusive evidence that such Certificated Warrant 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. The Authentication by the Warrant Agent on any such Certificated Warrant hereunder shall not be construed
as a representation or warranty by the Warrant Agent as to the validity of this Indenture or of such Warrant or its issuance (except the due Authentication thereof and any other warranties by law) 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 the proceeds thereof. 

 

	(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. Authenticating by way of entry on the register of Warrants maintained by the Warrant Agent shall not be construed as a representation or warranty by the Warrant Agent as to the validity of this
Indenture of such 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 the proceeds thereof.

 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 Warrantholders, the date of Authentication thereof and the number of Warrants; 

  

	 	(b)	whether such Warrant is a Certificated Warrant 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. 

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 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, 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. 

  
 10 

	(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 Laws), 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. 

 

	(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 tendered for exchange shall be
surrendered to the Warrant Agency and cancelled by the Warrant Agent. 

 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”, (b) in the case of Book Entry Warrants, in accordance with procedures prescribed by the Depository under its 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 Laws 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 Certificated Warrant, a Warrant Certificate, and to the transferee of an Uncertificated Warrant,
an Uncertificated Warrant (or it shall Authenticate and deliver a Certificated Warrant instead, upon request), representing the Warrants transferred and the transfer of a Book Entry Warrant shall be recorded through the relevant Book Entry
Participant in accordance with the book entry registration system as the entitlement holder in respect of such Warrants. 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)	Subject to the provisions of this Indenture and Applicable Law, the Warrantholder shall be entitled to the rights and privileges attaching to the Warrants, and the issue of Common 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 Common 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.

 ARTICLE 3

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) Common Share for each Warrant after the Issue Date and prior to the Expiry Time and in accordance with the conditions herein. 

Section 3.2 Warrant Exercise. 
  

	(1)	Registered Warrantholders who wish to exercise the Certificated Warrants held by them in order to acquire Common 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,
materially and adversely affect the rights, entitlements and interests of the Warrantholders, and deliver such certificate(s), the executed Exercise Notice and a certified check, bank draft or money order payable to or to the order of the
Corporation for the 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 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)	A beneficial holder 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 deliver to the Depository on behalf of the entitlement holder, notice of the owner’s intention to exercise Warrants in a manner acceptable to the Depository. Forthwith upon receipt by the Depository of such notice as well
as payment for the Exercise Price, the Depository shall deliver to the Warrant Agent confirmation of its intention to exercise Warrants (a “Confirmation”) in a manner acceptable to the Warrant Agent, including by electronic means
through a book based registration system. 

  

	(3)	Payment representing the 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 Depository and for the Depository in turn to deliver notice and payment
to the Warrant Agent prior to the Expiry Time. The Depository will initiate the exercise by way of the Confirmation and forward the Exercise Price electronically to the Warrant Agent and the Warrant Agent will execute the exercise by issuing to the
Depository through the book entry registration system the Common 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. 

  

	(4)	By causing a Book Entry Participant to deliver notice to the Depository, 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 Common Shares in connection with the obligations arising from such exercise. 

 

	(5)	Any notice which the Depository determines to be incomplete, not in proper form or not duly executed shall for all purposes be void and of no effect and the exercise to which it relates shall be considered for all
purposes not to have been exercised thereby. A failure by a 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. 

  
 12 

	(6)	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 representatives or an attorney of the Registered Warrantholder,
duly appointed by an instrument in writing satisfactory to the Warrant Agent but such Exercise Notice need not be executed by the Depository. 

  

	(7)	Any exercise referred to in this Section 3.2 shall require that the entire Exercise Price for Common Shares subscribed must be paid at the time of subscription and such Exercise Price and original Exercise Notice
executed by the Registered Warrantholder or the Confirmation from the Depository must be received by the Warrant Agent prior to the Expiry Time. 

  

	(8)	Notwithstanding the foregoing in this Section 3.2, Warrants may only be exercised pursuant to this Section 3.2 by or on behalf of a Registered Warrantholder, as applicable, who makes one of the certifications
set forth on the Exercise Notice set out in Schedule “B”. 

  

	(9)	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. 

 

	(10)	Exercise Notices and Confirmations 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 or
Confirmations 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. 

 

	(11)	Any Warrant with respect to which an Exercise Notice or a Confirmation is not received by the Warrant Agent before the Expiry Time on the Expiry Date shall be deemed to have expired and become void and all rights with
respect to such Warrants shall terminate and be cancelled. 

  

	(12)	Notwithstanding any provisions herein, a beneficial owner of Warrants issued in uncertificated form evidenced by a security entitlement in respect of Warrants in a book entry registration system who desires to exercise
his or her Warrants must do so by causing a Participant to deliver to DTC on behalf of the entitlement holder, an irrevocable notice of the owner’s intention to exercise Warrants in a manner acceptable to DTC prior to the Expiry Time. Forthwith
upon receipt by DTC of such notice, DTC shall deliver forthwith to the Warrant Co-Agent. Upon receipt by the Warrant Co-Agent of such notice and the aggregate Exercise Price of the Warrants, which may be delivered up to 4 business days after the
Expiry Date, the Warrant Co-Agent shall issue the resulting shares. 

 Section 3.3 [RESERVED] 

Section 3.4 Transfer Fees and Taxes. 

If any of the Common 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 Common 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. 

Section 3.5 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, furnish a list of the names and addresses of Registered Warrantholders showing the number of Warrants held by each such
Registered Warrantholder. 

  
 13 

 Section 3.6 Effect of Exercise of Warrant Certificates. 

 

	(1)	Upon the exercise of Warrants pursuant to and in compliance with Section 3.2 and subject to Section 3.3 and Section 3.4, the Common Shares to be issued pursuant to the Warrants exercised shall be deemed
to have been issued and the person or persons to whom such Common Shares are to be issued shall be deemed to have become the holder or holders of such Common Shares within three Business Days of the Exercise Date unless the transfer registers of the
Corporation shall be closed on such date, in which case the Common 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 Common Shares, on the date on which
such transfer registers are reopened. It is hereby understood that in order for beneficial holders to be holders of Common Shares on record on an 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 close of business on such Exercise Date. 

  

	(2)	Within three 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 Common Shares subscribed for, or any other appropriate evidence of the issuance of Common Shares to such person or persons in respect of Common Shares issued under the book entry registration system. 

Section 3.7 Partial Exercise of Warrants; Fractions. 
  

	(1)	The holder of any Warrants may exercise his right to acquire a number of whole Common 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 Common Shares.
Warrants may only be exercised in a sufficient number to acquire whole numbers of Common Shares. 

 Section 3.8 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 3.9
Accounting and Recording. 
  

	(1)	The Warrant Agent shall promptly account to the Corporation with respect to Warrants exercised. 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 Common Shares on exercise and the Exercise Date, in
respect thereof. The Warrant Agent shall provide such particulars in writing to the Corporation within five Business Days of any request by the Corporation therefor. 

  
 14 

 Section 3.10 Securities Restrictions. 

 

	(1)	Notwithstanding any provision to the contrary, Warrants may only be transferred, Common Shares shall only be issued by the Corporation (upon exercise of the Warrants), and Common Shares may only be transferred in
compliance with Applicable Law, including without limitation Securities Laws. Without limiting the generality of the foregoing, the Corporation may direct the Warrant Agent to prohibit exercise of the Warrants or to legend any Warrant
Certificates or certificates representing the Common Shares if, in the opinion of counsel to the Corporation, such prohibition or legend is necessary or appropriate in order to avoid a violation of applicable Securities Laws; provided that if, at
any time, in the opinion of outside counsel to the Corporation, acting reasonably, such legends are no longer necessary in order to avoid a violation of any such laws, or the holder of any such legended certificate, at his expense, provides the
Corporation with evidence satisfactory in form and substance to the Corporation (which may include an opinion of counsel of recognized standing satisfactory to the Corporation) to the effect that such holder is entitled to sell or otherwise transfer
such securities in a transaction in which such legends are not required, such legended certificates may thereafter be surrendered to the Corporation in exchange for a certificate which does not bear such legends. 

 

	(2)	The Warrant Agent shall be entitled to assume that Common Shares may be issued pursuant to the exercise of any Warrant without violating any applicable Securities Laws and without legending any certificate representing
the Common Shares unless the Warrant Agent has received notice in writing from the Corporation stating otherwise and setting forth the restrictions on the exercise of the Warrants and any legend the certificates representing the Common Shares should
bear. 

  

	(3)	 Neither the Corporation nor the Warrant Agent shall effect any exercise of a Warrant, and a Holder shall not have
the right to exercise any portion of a Warrant, pursuant to Article 3 or otherwise, to the extent that, after giving effect to such issuance after exercise as set forth on the applicable Exercise Form, the Holder (together with the
Holder’s affiliates, and any other Persons acting as a group together with the Holder or any of the Holder’s affiliates (such Persons, “Attribution Parties”)), would beneficially own in excess of the Beneficial Ownership
Limitation (as defined below). For purposes of the foregoing sentence, the number of Common Shares beneficially owned by the Holder and its affiliates and Attribution Parties shall include the number of Common Shares issuable upon exercise of a
Warrant with respect to which such determination is being made, but shall exclude the number of Common Shares that would be issuable upon (i) exercise of the remaining, non-exercised portion of a Warrant
beneficially owned by the Holder or any of its affiliates or Attribution Parties, and (ii) exercise or conversion of the unexercised or unconverted portion of any other convertible securities of the Corporation, subject to a limitation on
conversion or exercise analogous to the limitation contained herein, beneficially owned by the Holder or any of its affiliates or Attribution Parties. Except as set forth in the preceding sentence, for purposes of this Section 3.10(3),
beneficial ownership shall be calculated in accordance with Section 13(d) of the U.S. Securities Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that neither the Warrant Agent nor
the Corporation is representing to the Holder that such calculation is in compliance with Section 13(d) of the U.S. Securities Exchange Act and the Holder further acknowledges that it is solely responsible for any schedules required to be
filed in accordance therewith. To the extent that the limitation contained in this Section 3.10(3) applies, the determination of whether a Warrant is exercisable (in relation to other securities owned by the Holder together with any
affiliates and Attribution Parties) and of which portion of a Warrant is exercisable shall be in the sole discretion of the Holder, and the submission of an Exercise Form shall be deemed to be the Holder’s determination of whether a
Warrant is exercisable (in relation to other securities owned by the Holder together with any affiliates and Attribution Parties) and of which portion of a Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and
neither the Warrant Agent nor the Corporation shall have any obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with
Section 13(d) of the U. S. Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 3.10(3), in determining the number of outstanding Common Shares, a Holder may rely on the number of
outstanding Common Shares as reflected in (A) the Corporation’s most recent periodic or annual report filed with the SEC or on SEDAR, as the case may be, (B) a more recent public announcement by the Corporation, or (C) a more
recent written notice by the Corporation or the Corporation’s transfer agent setting forth the number of Common Shares outstanding. Upon the written or oral request of a Holder, the Corporation shall, within two Trading Days, confirm orally and
in writing to the Holder the number of Common Shares then outstanding. In any case, the number of outstanding Common Shares shall be determined after giving effect to the conversion or exercise of securities of the Corporation, including the
Warrant being exercised, by the Holder or its affiliates or Attribution Parties since the date as of which such number of outstanding Common Shares was 

  
 15 

	 	
reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of Common Shares outstanding immediately after giving effect to the issuance of Common Shares
issuable upon exercise of the Warrant in question. The Holder, upon written notice to the Corporation, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 3.10(3), provided that the Beneficial Ownership
Limitation in no event exceeds 9.99% of the number of Common Shares outstanding immediately after giving effect to the issuance of Common Shares upon exercise of the Warrant in question held by the Holder and the provisions of this
Section 3.10(3) shall continue to apply. Any increase in the Beneficial Ownership Limitation will not be effective until the sixty-first (61st) day after such notice is delivered to the Corporation. The provisions of this paragraph
shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 3.10(3) to correct this paragraph (or any portion hereof) that may be defective or inconsistent with the intended Beneficial
Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this Section 3.10(3) shall apply to a successor holder of a Warrant.

 ARTICLE 4

ADJUSTMENT OF NUMBER OF COMMON SHARES

AND EXERCISE PRICE 
 Section 4.1
Adjustment of Number of Common Shares and Exercise Price. 
  

	(1)	The rights to acquire Common Shares hereunder are subject to adjustment from time to time as follows: 

  

	 	(a)	if and whenever at any time from the date hereof and prior to the Expiry Time, the Corporation: 

  

	 	(i)	subdivides its outstanding Common Shares into a greater number of shares; 

  

	 	(ii)	consolidates its outstanding Common Shares into a smaller number of shares; or 

  

	 	(iii)	issues Common Shares or securities exchangeable for or convertible into Common Shares (collectively, “convertible securities”) to the holders of all or substantially all of the outstanding Common Shares
by way of a stock distribution, stock dividend or otherwise, 

 any of such events in these clauses (i), (ii) and (iii) being called a
“Common Share Reorganization”, the Exchange Rate shall be adjusted immediately after the effective date of the subdivision or consolidation or on the record date for the issue of Common Shares or convertible securities by way of
stock distribution, stock dividend or otherwise, by multiplying the Exchange Rate by the fraction of which: 
  

	 	(A)	the numerator is the total number of Common Shares outstanding immediately after such effective or record date, or, in the case of the issuance of convertible securities, the total number of Common Shares outstanding
immediately after such date plus the total number of Common Shares issuable upon conversion or exchange of such convertible securities; and 

  

	 	(B)	the denominator is the total number of Common Shares outstanding immediately prior to the applicable effective or record date; 

and the Exercise Price shall be adjusted at the same time by multiplying the Exercise Price in effect at the time of such event by the inverse of the
aforesaid fraction. The Corporation shall make such adjustment successively whenever any event referred to in this Section 4.1(1)(a) occurs and any such issue of Common Shares or convertible securities by way of a stock dividend is deemed to
have occurred on the record date for the stock dividend for the purpose of calculating the number of outstanding Common Shares under this Section 4.1(1)(a). 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. To the extent that any convertible securities are not converted into or exchanged for Common Shares, the Exchange Rate shall be readjusted to the number of Common Shares that is then
obtainable based upon the number of Common Shares actually issued on conversion or exchange of such convertible securities; 

  
 16 

	 	(b)	if and whenever at any time from the date hereof and prior to the Expiry Time the Corporation shall fix a record date for the issue of rights, options or warrants to all or substantially all of the holders of Common
Shares under which such holders are entitled, during a period expiring not more than 45 days after the record date for such issue (“Rights Period”), to subscribe for or acquire Common Shares (or securities convertible or
exchangeable into Common Shares) at a price per share (or having a conversion or exchange price per Common Share) to the holder of less than 95% of the Current Market Price for the Common Shares on such record date (any of such events being called a
“Rights Offering”), then, in each case: 

  

	 	(i)	the Warrantholder will be entitled to acquire, upon the terms applicable to such Rights Offering, the aggregate number of Common Shares that the Warrantholder would have acquired if the Warrantholder had held all Common
Shares immediately before such record date; provided, however, to the extent that the Warrantholder’s right to participate in any such Rights Offering would result in the Warrantholder exceeding the Beneficial Ownership Limitation, then the
Warrantholder shall not be entitled to participate in such Rights Offering (or deemed to have beneficial ownership of such Common Shares as a result of such Rights Offering to such extent) to such extent, and that portion of the Rights Offering
shall be held in abeyance for the benefit of the Warrantholder until such time, if ever, as its right thereto would not result in the Warrantholder exceeding the Beneficial Ownership Limitation; and 

 

	 	(ii)	the Exercise Price shall be adjusted effective immediately after the end of the Rights Period to a number determined by multiplying the Exercise Price in effect on such record date by a fraction: 

 

	 	(A)	the numerator of which shall be the number of Common Shares outstanding as of the record date for the Rights Offering 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 

 

	 	(B)	the denominator of which shall be the number of Common Shares outstanding as of the record date for the Rights Offering 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. To the extent that any rights, options or warrants so distributed are not exercised prior to the expiration thereof, the number of Common
Shares and the Exercise Price shall be readjusted to that number and Exercise Price that would then be in effect if such record date had not been fixed or, if any rights or warrants are exercised, to that number and 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, options or warrants, as the case may be. 

 

	 	(c)	if and whenever at any time from the date hereof and prior to the Expiry Time the Corporation shall issue or distribute to all or to substantially all the holders of the Common Shares: 

 

	 	(i)	securities of the Corporation of any class other than Common Shares or convertible securities, or rights, options or warrants other than rights, options or warrants exercisable within 45 days from the date of issue
thereof at a price, or at a conversion price, of at least 95% of the Current Market Price at the record date for such distribution, 

  

	 	(ii)	evidences of indebtedness of the Corporation, or 

  

	 	(iii)	any property or other assets (excluding cash dividends), 

  
 17 

 and if such issuance or distribution does not constitute a Common Share Reorganization or a Rights Offering (any
of such non-excluded events being herein called a “Special Distribution”), then, in each case: 
  

	 	(A)	the Warrantholder shall be entitled to participate in such Special Distribution to the same extent that the Warrantholder would have participated therein if the Warrantholder had held all Warrant Shares immediately
before such record date; provided, however, to the extent that the Warrantholder’s right to participate in any such Special Distribution would result in the Warrantholder exceeding the Beneficial Ownership Limitation, then the Warrantholder
shall not be entitled to participate in such Special Distribution (or deemed to have beneficial ownership of such Common Shares as a result of such Special Distribution) to such extent, and that portion of the Special Distribution shall be held in
abeyance for the benefit of the Warrantholder until such time, if ever, as its right thereto would not result in the Warrantholder exceeding the Beneficial Ownership Limitation. To the extent that a Warrantholder’s Warrants have not been
partially or completely exercised at the time of such Special Distribution, such portion of the Special Distribution shall be held in abeyance for the benefit of the Warrantholder until the Warrantholder has exercised the Warrantholder’s
Warrants as to such undistributed amount of the Special Distribution; and 

  

	 	(B)	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: 

 

	 	(x)	the numerator of which shall be the number of Common Shares outstanding on such record date multiplied by the Current Market Price of the Common Shares 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, subject to Nasdaq and TSX approval), 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 

  

	 	(y)	the denominator of which shall be the number of Common Shares outstanding on such record date multiplied by the Current Market Price of the Common Shares on such record date; 

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. To the
extent that the distribution of shares, rights, options, warrants, evidences of indebtedness or assets is not so made or any rights, options or warrants so distributed are not exercised, the number of Common Shares and the Exercise Price shall be
readjusted to that number and Exercise Price that would then be in effect based upon the shares, rights, options, warrants, evidences of indebtedness or assets actually distributed or based upon the number of Common Shares or convertible securities
actually delivered upon the exercise of the rights, options or warrants, as the case may be, but subject to any other adjustment required hereunder by reason of any event arising after the record date. 

 

	 	(d)	if and whenever at any time from the date hereof and prior to the Expiry Time, there is a reclassification of the Common Shares or a capital reorganization of the Corporation other than as described in
Section 4.1(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 (any such event being herein called a “Capital Reorganization”), the holder is entitled to receive upon exercise in accordance with the terms and conditions hereof and shall accept, in lieu
of the Exchange Rate to which it was previously entitled, the kind and number of Common Shares or other securities or property that the holder would have been entitled to receive on such Capital Reorganization, if, on the record date or the
effective date thereof, as the case may be, the holder had been the registered holder of the number of Common Shares obtainable upon the exercise of Warrants then held, subject to adjustment thereafter in accordance with provisions the same, as
nearly as may be possible, as those contained in this Section 4.1(1)(d); 

  
 18 

	(2)	The following rules and procedures shall be applicable to adjustments made pursuant to Section 4.1: 

  

	 	(a)	where Section 4.1 requires that an adjustment becomes effective immediately after a record date or effective date, as the case may be for an event referred to herein, the Corporation may defer, until the occurrence
of that event, issuing to the holder exercising its acquisition rights after the record date or effective date, as the case may be and before the occurrence of that event the adjusted number of Common Shares, other securities or property issuable
upon the exercise of the Warrants by reason of the adjustment required by that event. If the Corporation relies on this Section 4.1(2)(a) to defer issuing an adjusted number of Common Shares, other securities or property to the holder, the
holder has the right to receive any distributions made on the adjusted number of Common Shares, other securities or property declared in favor of shareholders of record on and after the Exercise Date or such later date as the holder would, but for
the provisions of this Section 4.1(2)(a), have become the holder of record of the adjusted number of Common Shares, other securities or property pursuant to Section 4.1; 

 

	 	(b)	the adjustments provided for in Section 4.1 are cumulative and, subject to Section 4.1(2)(c), shall apply (without duplication) to successive issues, subdivisions, combinations, consolidations, distributions
and any other events that require adjustment under Section 4. After any adjustment pursuant to Section 4, the term “Common Share” where used in the Warrant Certificate shall be interpreted to mean securities of any class or
classes which, as a result of such adjustment and all prior adjustments pursuant to Section 4.1, the holder is entitled to receive upon the exercise of its Warrant, and the number of Common Shares obtainable in any exercise made pursuant to a
Warrant shall be interpreted to mean the number of Common Shares the holder is entitled to receive, as a result of such adjustment and all prior adjustments pursuant to Section 4.1, upon the full exercise of a Warrant; 

 

	 	(c)	no adjustment in the number of Common Shares or other securities issuable on the exercise of the Warrants shall be required unless the adjustment would result in a change of at least 1% in the number of Common Shares or
other securities then issuable on the exercise of the Warrants, provided, however, that any adjustments that, except for the provisions of this Section would otherwise have been required to be made, shall be carried forward and taken into account in
any subsequent adjustment; 

  

	 	(d)	all shares of any class which the holder is at the time in question entitled to receive on the exercise of a Warrant, whether or not as a result of adjustments made pursuant to Section 4.1 are, for the purposes of
the interpretation of the Warrant Certificate, deemed to be securities which the holder is entitled to acquire pursuant to the exercise of a Warrant; 

  

	 	(e)	if the Corporation shall set a record date to determine the holders of the Common Shares for the purpose of entitling them to receive any dividend or distribution or any subscription or exercise rights and shall,
thereafter and before the distribution to such shareholders of any such dividend, distribution or subscription or exercise rights, legally abandon its plan to pay or deliver such dividend, distribution or subscription or exercise rights, then no
adjustment in the number of Common Shares obtainable upon exercise of any Warrant shall be required by reason of the setting of such record date; and 

  

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

 Section 4.2 Entitlement to Common 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 Common Shares which such Registered Warrantholder is entitled
to acquire pursuant to such Warrant. 

  
 19 

 Section 4.3 Fundamental Transactions. 

If, at any time while this Warrant is outstanding, (i) the Corporation, directly or indirectly, in one or a series of related
transactions, (A) effects any merger, consolidation or reorganization or other similar transaction or a series of related transactions which results in the voting securities of the Corporation outstanding immediately prior thereto representing
immediately thereafter (either by remaining outstanding or by being converted into voting securities of the surviving or acquiring entity) less than 50% of the combined voting power of the voting securities of or economic interests in the
Corporation or such surviving or acquiring entity outstanding immediately after such merger, consolidation or reorganization, (B) effects any sale, lease, license, assignment, transfer, conveyance, distribution or other disposition of all or
substantially all of its assets, (C) effects any reclassification, reorganization or recapitalization of the Common Shares or any compulsory share exchange pursuant to which the Common Shares is effectively converted into or exchanged for other
securities, cash or property (except for issuances by reclassification contemplated by Section 11(a)(iv) or transactions for the purpose of changing the domicile of the Corporation), or (D) consummates a
stock or share purchase agreement or other business combination (including a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person or “group” (within the meaning of
Section 13(d) or 14(d) of the U.S. Exchange Act) whereby such other Person or “group” acquires more than 50% of the voting power of or economic interests in the then outstanding shares of capital stock of the Corporation (after giving
effect to such transaction), or (ii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Corporation or another Person or group of Persons) is completed pursuant to which holders of Common Shares are
permitted to sell, tender or exchange their shares for other securities, cash or property (each transaction or series of transactions referred to in clause (i) or (ii) above, a “Fundamental Transaction”); then, the Corporation
shall (x) unless such Fundamental Transaction is an unsolicited third-party tender offer, use its best efforts to ensure that lawful and adequate provision shall be made whereby the Registered Warrantholder shall thereafter continue to have the
right to purchase and receive, upon the basis and upon the terms and conditions herein specified (or as nearly equivalent as practicable), and in lieu of the Common Shares immediately theretofore issuable upon exercise of this Warrant, shares in the
surviving or acquiring entity in the Fundamental Transaction (such entity, or the parent thereof in a consolidated group, the “Acquirer”) with an aggregate value equal to the Black Scholes Value of the Registered
Warrantholder’s Warrants (an “Acquirer Assumption”); and (y) if an Acquirer Assumption does not occur, the Acquirer shall pay to the Registered Warrantholder an amount equal to the aggregate value equal to the Black
Scholes Value of the Registered Warrantholder’s Warrants in the same form and percentage consideration (e.g., 50% cash, 30% stock, 10% securities, and 10% other non-cash consideration) that the Acquirer
pays to the Corporation’s shareholders as consideration for the Fundamental Transaction. 
 Section 4.4 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 4.5
Determination by Independent Auditors. 
 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 the Auditors, or if they are unwilling or unable to do so by such other independent registered public accounting firm as may be selected by the board of directors of the Corporation, who

 Section 4.6 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 Common 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 Common Shares which the holders of such Warrants are entitled to receive on the full exercise thereof in
accordance with the provisions hereof. 
 Section 4.7 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 adjustment or readjustment 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 shall be supported by a certificate of the Corporation’s Auditors verifying such calculation. 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 4.8 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 4.9 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.

 Section 4.10 Other Adjustments. 

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 opinion of the directors of the Corporation would have a material adverse effect on the rights of Registered Warrantholders, the Exercise Price and/or the Exchange Rate, there shall be an adjustment in such manner, if any, and at such
time, by action of the directors of the Corporation, acting reasonably, in their sole discretion as they may determine to be equitable to the Registered Warrantholders in such circumstances, subject in each case to the prior approval of any
securities exchange on which the Common Shares are listed for trading. 
 Section 4.11 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 said adjustment; 

  
 21 

	 	(b)	be accountable with respect to the validity or value (or the kind or amount) of any Common 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 Common 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 4.12 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. 

ARTICLE 5
 RIGHTS OF THE
CORPORATION AND COVENANTS 
 Section 5.1 Optional Purchases by the Corporation. 

Subject to compliance with applicable Securities Laws and approval of applicable regulatory authorities, 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 Certificated Warrants, 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 Warrant and in accordance with procedures prescribed by the Depository under the book entry registration system. No Warrants shall be issued in replacement thereof. 

Section 5.2 General Covenants. 
 The
Corporation covenants with the Warrant Agent that so long as any Warrants remain outstanding: 
  

	 	(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 Common Shares upon the exercise of the Warrants; 

 

	 	(b)	it will cause the Common 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;

and conditions, and such Common Shares 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, provided that this clause shall not be construed as limiting or restricting the Corporation to agree
to a consolidation, amalgamation, arrangement, takeover bid, or merger even if the transaction would alter the Corporation’s existence or business in the ordinary course; 

  
 22 

	 	(e)	it will use commercially reasonable efforts to ensure that all Common Shares outstanding or issuable from time to time (including the Common Shares) continue to be or are listed for trading on the Nasdaq, TSX or a U.S.
national securities exchange, provided that this clause shall not be construed as limiting or restricting the Corporation from agreeing to a consolidation, amalgamation, arrangement, takeover bid or merger even if the consideration being offered is
not securities that are so listed for trading; 

  

	 	(f)	it will make all requisite filings under applicable Securities Laws, including those necessary to remain a reporting issuer not in default in each of the provinces and other jurisdictions where it is or becomes a
reporting issuer and under the federal securities laws of the United States, provided that this clause shall not be construed as limiting or restricting the Corporation from agreeing to a consolidation, amalgamation, arrangement, takeover bid, or
merger even if the transaction would result the Corporation not being such a reporting issuer; 

  

	 	(g)	if in the opinion of counsel to the Warrant Agent, any instrument is required to be filed with, or any permission is required to be obtained from. the SEC, any other securities regulatory authority, or any securities
exchange upon which the Common Shares (or the Warrants) are listed, or any other step is required under Securities Laws before any Common Shares may properly and legally be issued (upon due exercise thereof) and thereafter traded, without further
formality or restriction, the Corporation will use its commercially reasonable best efforts to take such action as is required or appropriate in the circumstances; 

 

	 	(h)	it will cause the Warrant Agent to keep open the registers of Holders and transfers of Warrants referred to in Section 2.9 and will not take any action or omit to take any action which would have the effect of
preventing the Holders from exercising any of the Warrants or receiving any of the Common Shares upon such exercise; and 

  

	 	(i)	it will promptly notify the Warrant Agent and the Holders in writing of any default under the terms of this Indenture which remains unrectified for more than five days following its occurrence; and 

 

	 	(j)	generally, it will use commercially reasonable efforts to perform and carry out all of the acts or things to be done by it as provided in this Indenture. 

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. 
 Section 5.4 Performance of Covenants by Warrant Agent. 

If the Corporation shall fail to perform any of its covenants contained in this Indenture, the Warrant Agent may notify the Registered
Warrantholders of such failure on the part of the Corporation or 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. 

  
 23 

 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,

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.

Such notice shall state 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 on the matter, but it shall not be necessary for any such notice to set out the terms of any resolution to be proposed or any of the provisions of this Section 7.2. 

Section 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 if no individual is so designated, or if the individual so designated is not present within fifteen minutes from the time

except that votes on an Extraordinary Resolution shall be given in the manner hereinafter provided. At any such meeting, unless a poll is duly demanded as herein provided, a declaration by the chairman that a resolution has been carried or carried

Registered Warrantholder present in person or represented by a proxy duly appointed by instrument in writing shall be entitled to one vote in respect of each Warrant then held or represented by it. A proxy need not be a Registered Warrantholder. The

Agent’s prior consent, acting reasonably) or on behalf of the Registered Warrantholders against the Corporation whether such rights arise under this Indenture or otherwise; provided that, for greater certainty, no rights or obligations of the

properly incurred by such Registered Warrantholder in connection therewith; 

  

	 	(g)	to assent to any change in or omission from the provisions contained in this Indenture or any ancillary or supplemental instrument which may be agreed to by the Corporation, and to authorize the Warrant Agent to concur
in and execute any ancillary or supplemental indenture embodying the change or omission;

Warrant Agent so removed; and 

  

	 	(i)	to assent to any compromise or arrangement with any creditor or creditors or any class or classes of creditors, whether secured or otherwise, and with holders of any shares or other securities of the Corporation.

 Section 7.11 Meaning of Extraordinary Resolution. 
  

	(1)	The expression “Extraordinary Resolution” when used in this Indenture means, subject as hereinafter provided in this Section 7.11 and in Section 7.14, a resolution proposed at a meeting of
Registered Warrantholders duly convened for that purpose and held in accordance with the provisions of this Article 7 at which there are present in person or by proxy Registered Warrantholders holding at least 25% of the aggregate number of then

Request, shall be dissolved; but in any other case the meeting shall be adjourned to such day, being not less than 15 or more than 60 days later, and to such place and time as may be appointed by the chairman. Not less than 14 days’ prior
notice shall be given of the time and place of such 

  
 27 

	 	
adjourned meeting in the manner provided for in Section 10.2. Such notice shall state that at the adjourned meeting the Registered Warrantholders present in person or by proxy shall form a
quorum but it shall not be necessary to set forth the purposes for which the meeting was originally called or any other particulars. At the adjourned meeting the Registered Warrantholders present in person or by proxy shall form a quorum and may
transact the business for which the meeting was originally convened and a resolution proposed at such adjourned meeting and passed by the requisite vote as provided in Section 7.11(1) shall be an Extraordinary Resolution within the meaning of
this Indenture notwithstanding that Registered Warrantholders representing at least 25% of the aggregate number of then outstanding Warrants are not present in person or by proxy at such adjourned meeting.

convened and held, and all resolutions passed thereat or proceedings taken shall be deemed to have been duly passed and taken. 
 Section 7.14
Instruments in Writing. 
 All actions which may be taken and all powers that may be exercised by the Registered Warrantholders at a
meeting held as provided in this Article 7 may also be taken and exercised by Registered Warrantholders holding not less than
66 2/3% of the aggregate number of then outstanding Warrants by an instrument in writing signed in one or more counterparts by such
Registered Warrantholders in person or by attorney duly appointed in writing, and the expression “Extraordinary Resolution” when used in this Indenture shall include an instrument so signed.

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

	(2)	In the exercise of its rights and duties hereunder, the Warrant Agent may, if it is acting in 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 Corporation, certificates of the Corporation or other evidence furnished to the Warrant Agent pursuant to a request of the Warrant Agent, or pursuant to any provision hereof or any
Applicable Law. 

  
 30 

	(3)	Whenever it is provided in this Indenture or under Applicable Law that the Corporation shall deposit with the Warrant Agent resolutions, certificates, reports, opinions, requests, orders or other documents, it is
intended that the truth, accuracy and good faith on the effective date thereof and the facts and opinions stated in all such documents so deposited shall, in each and every such case, be conditions precedent to the right of the Corporation to have
the Warrant Agent take the action to be based thereon. 

  

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

  

	(5)	The Warrant Agent may act and rely and shall be protected in acting and relying in good faith on the opinion or advice of or information obtained from any counsel, accountant, appraiser, engineer or other expert or
adviser, whether retained or employed by the Corporation or by the Warrant Agent, in relation to any matter arising in the administration of the agency hereof.

	(2)	Any written direction for the investment or release of funds received shall be received by the Warrant Agent by 9:00 a.m. (Toronto time) on the Business Day on which such investment or release is to be made, failing
which such direction will be handled on a commercially reasonable efforts basis and may result in funds being invested or released on the next Business Day. 

  

	(3)	The Warrant Agent shall have no responsibility or liability for any diminution of any funds resulting from any investment made in accordance with this Indenture, including any losses on any investment liquidated prior
to maturity in order to make a payment required hereunder. 

  

	(4)	In the event that the Warrant Agent does not receive a direction or only a partial direction, the Warrant Agent may hold cash balances constituting part or all of such monies and may, but need not, invest same in its
deposit department, the deposit department of one of its affiliates, or the deposit department of a Canadian chartered bank; but the Warrant Agent, its affiliates or a Canadian chartered bank shall not be liable to account for any profit to any
parties to this Indenture or to any other person or entity.

	 	(a)	the Warrant Agent shall not be liable for or by reason of any statements of fact or recitals in this Indenture or in the Warrant Certificates (except the representation contained in Section 9.9 or in the
Authentication of the Warrant Agent on the Warrant Certificates) or be required to verify the same, but all such statements or recitals are and shall be deemed to be made by the Corporation; 

  
 31 

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

  

	 	(c)	the Warrant Agent shall not be bound to give notice to any person or persons of the execution hereof;

acts of any directors, officers, employees, agents or servants of the Corporation; 

  

	 	(e)	the Corporation hereby indemnifies and agrees to hold harmless the Warrant Agent, its affiliates, their officers, directors, employees, agents, successors and assigns (the ”Indemnified Parties”) from

deed, matter or thing whatsoever made, done, acquiesced in or omitted in or about or in relation to the execution of the Indemnified Parties’ duties, or any other services that the Warrant Agent may provide in connection with or in any way
relating to this Indenture. The Corporation agrees that its liability hereunder shall be absolute and unconditional regardless of the correctness of any representations of any third parties and regardless of any liability of third parties to the
Indemnified Parties, and shall accrue and become enforceable without prior demand or any other precedent action or proceeding; provided that the Corporation shall not be required to indemnify the Indemnified Parties in the event of the gross
negligence, willful misconduct, bad faith or fraud of the Warrant Agent, and this provision shall survive the resignation or removal of the Warrant Agent or the termination or discharge of this Indenture; and 

 

	 	(f)	notwithstanding the foregoing or any other provision of this Indenture, any liability of the Warrant Agent shall be limited, in the aggregate, to the amount of annual retainer fees paid by the Corporation to the Warrant
Agent under this Indenture in the twelve (12) months immediately prior to the Warrant Agent receiving the first notice of the claim. Notwithstanding any other provision of this Indenture, and whether such losses or damages are foreseeable or
unforeseeable, the Warrant Agent shall not be liable under any circumstances whatsoever for any (a) breach by any other party of securities law or other rule of any securities regulatory authority, (b) lost profits or (c) special,
indirect, incidental, consequential, exemplary, aggravated or punitive losses or damages. 

 Section 9.8 Replacement of Warrant Agent;
Successor by Merger 
  

	(1)	The Warrant Agent may resign its agency and be discharged from all further duties and liabilities hereunder, subject to this Section 9.8, by giving to the Corporation not less than 60 days’ prior notice in
writing or such shorter prior notice as the Corporation may accept as sufficient. The Registered Warrantholders by Extraordinary Resolution shall have power at any time to remove the existing Warrant Agent and to appoint a new Warrant Agent. In the
event of the Warrant Agent resigning or being removed as aforesaid or being dissolved, becoming bankrupt, going into liquidation or otherwise becoming incapable of acting hereunder, the Corporation shall forthwith appoint a new Warrant agent unless
a new Warrant Agent has already been appointed by the Registered Warrantholders; failing such appointment by the Corporation, the retiring Warrant Agent or any Registered Warrantholder may apply to any court of competent jurisdiction for the
appointment of a new warrant agent; but any new warrant agent so appointed by the Corporation or by the Court shall be subject to removal as aforesaid by the Registered Warrantholders. Any new Warrant Agent appointed under any provision of this
Section 9.8 shall be an entity authorized to carry on the business of a trust company in Canada or a province thereof, the United States or a state thereof and, if required by the Applicable Law for any other states or provinces, in such other
states or provinces. On any such appointment the new Warrant Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as Warrant Agent hereunder. 

 

	(2)	Upon the appointment of a successor Warrant Agent, the Corporation shall promptly notify the Registered Warrantholders thereof in the manner provided for in Section 10.2. 

  
 32 

	(3)	Any Warrant Certificates Authenticated but not delivered by a predecessor Warrant Agent may be Authenticated by the successor Warrant Agent in the name of the predecessor or successor Warrant Agent. 

 

	(4)	Any corporation in to which the Warrant Agent may be merged or consolidated or amalgamated, or any corporation resulting therefrom to which the Warrant Agent shall be a party, or any corporation succeeding to
substantially the corporate trust business of the Warrant Agent shall be the successor to the Warrant Agent hereunder without any further act on its part or any of the parties hereto, provided that such corporation would be eligible for appointment
as successor Warrant Agent under Section 9.8(1). 

 Section 9.9 Conflict of Interest 

 

	(1)	The Warrant Agent represents to the best of its knowledge to the Corporation that at the time of execution and delivery hereof no material conflict of interest exists between its role as a Warrant Agent hereunder and
its role in any other capacity and agrees that in the event of a material conflict of interest arising hereafter it will, within 30 days after ascertaining that it has such material conflict of interest, either eliminate the same or assign its
agency hereunder to a successor Warrant Agent approved by the Corporation and meeting the requirements set forth in Section 9.8(1). Notwithstanding the foregoing provisions of this Section 9.9(1), if any such material conflict of interest
exists or hereafter shall exist, the validity and enforceability of this Indenture and the Warrant Certificate shall not be affected in any manner whatsoever by reason thereof. 

 

	(2)	Subject to Section 9.9(1), the Warrant Agent, in its personal or any other capacity, may buy, lend upon and deal in securities of the Corporation and generally may contract and enter into financial transactions
with the Corporation without being liable to account for any profit made thereby. 

 Section 9.10 Acceptance of Agency.

conditions herein set forth.

The Warrant Agent shall not be bound to give any notice or do or take any act, action or proceeding by virtue of the powers conferred on it
hereby unless and until it shall have been required so to do under the terms hereof; nor shall the Warrant Agent be required to take notice of any default hereunder, unless and until notified in writing of such default, which notice shall distinctly
specify the default desired to be brought to the attention of the Warrant Agent and in the absence of any such notice the Warrant Agent may for all purposes of this Indenture conclusively assume that no default has been made in the observance or
performance of any of the representations, warranties, covenants, agreements or conditions contained herein. Any such notice shall in no way limit any discretion herein given to the Warrant Agent to determine whether or not the Warrant Agent shall
take action with respect to any default. 
 Section 9.13 Anti-Money Laundering. 

 

	(1)	Each party to this Indenture other than the Warrant Agent hereby represents to the Warrant Agent that any account to be opened by, or interest to be held by the Warrant Agent in connection with this Indenture, for or to
the credit of such party, either (i) is not intended to be used by or on behalf of any third party; or (ii) is intended to be used by or on behalf of a third party, in which case such party hereto agrees to complete and execute forthwith a
declaration in the Warrant Agent’s prescribed form as to the particulars of such third party. 

  
 33 

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

 Section 9.14 Compliance with Privacy Code. 

The Corporation acknowledges that the Warrant Agent may, in the course of providing services hereunder, collect or receive financial and other
personal information about such parties and/or their representatives, as individuals, or about other individuals related to the subject matter hereof, and use such information for the following purposes:

purposes. 

 The Corporation acknowledges and agrees that the Warrant Agent may receive, collect, use and disclose personal
information provided to it or acquired by it in the course of its acting as an agent hereunder for the purposes described above and, generally, in the manner and on the terms described in its privacy code, which the Warrant Agent shall make
available on its website or upon request, including revisions thereto. The Warrant Agent may transfer personal information to other companies in or outside of Canada that provide data processing and storage or other support in order to facilitate
the services it provides. Further, the Corporation agrees that it shall not provide or cause to be provided to the Warrant Agent any personal information relating to an individual who is not a party to this Indenture unless the Corporation has
assured itself that such individual understands and has consented to the aforementioned uses and disclosures. 
 Section 9.15 Securities and
Exchange Commission Certification. 
 The Corporation confirms that it has either (i) a class of securities registered pursuant to
Section 12 of the U.S. Exchange Act; or (ii) a reporting obligation pursuant to Section 15(d) of the U.S. Exchange Act, and has provided the Warrant Agent with a certificate of an officer of the Corporation (in a form provided by the

accordance with the U.S. Exchange Act, the Corporation shall promptly notify the Warrant Agent of such termination and such other information as the Warrant Agent may require at the time. The Corporation acknowledges that the Warrant Agent is
relying upon the foregoing representation and covenants in order to meet certain SEC obligations with respect to those clients who are filing with the SEC.

way responsible in the event that any payment is not delivered or received pursuant to this section. Notwithstanding the foregoing, in the event that the Corporation provides the refund to the Warrant Agent for distribution to the holder, the
Warrant Agent shall return such funds to the holder as soon as reasonably practicable, and in so doing, the Warrant Agent shall incur no liability with respect to the delivery or non-delivery of any such

The surrender of this Warrant Certificate, the duly completed Exercise Notice 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. 

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

Trust Company of Canada, 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

 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.

 CERTAIN REQUIREMENTS RELATING TO TRANSFERS – READ CAREFULLY 

The signature(s) of the transferor(s) must correspond with the name(s) as written upon the face of this certificate(s), in every particular, without alteration
or enlargement, or any change whatsoever. The signature(s) on this form must be guaranteed in accordance with the transfer agent’s then current guidelines and requirements at the time of transfer. Notarized or witnessed signatures are not
acceptable as guaranteed signatures. As at the time of closing, you may choose one of the following methods (although subject to change in accordance with industry practice and standards): 

 

	 	•	Canada and the USA: A Medallion Signature Guarantee obtained from a member of an acceptable Medallion Signature Guarantee Program (STAMP, SEMP, NYSE, MSP). Many commercial banks, savings banks, credit unions, and
all broker dealers participate in a Medallion Signature Guarantee Program. The Guarantor must affix a stamp bearing the actual words “Medallion Guaranteed”, with the correct prefix covering the face value of the certificate.

  

	 	•	Canada: A Signature Guarantee obtained from an authorized officer of the Royal Bank of Canada, Scotia Bank or TD Canada Trust. The Guarantor must affix a stamp bearing the actual words “Signature
Guaranteed”, sign and print their full name and alpha numeric signing number. Signature Guarantees are not accepted from Treasury Branches, Credit Unions or Caisse Populaires unless they are members of a Medallion Signature Guarantee Program.
For corporate holders, corporate signing resolutions, including certificate of incumbency, are also required to accompany the transfer, unless there is a “Signature & Authority to Sign Guarantee” Stamp affixed to the transfer (as
opposed to a “Signature Guarantee” Stamp) obtained from an authorized officer of the Royal Bank of Canada, Scotia Bank or TD Canada Trust or a Medallion Signature Guarantee with the correct prefix covering the face value of the
certificate. 

  

	 	•	Outside North America: For holders located outside North America, present the certificates(s) and/or document(s) that require a guarantee to a local financial institution that has a corresponding Canadian or
American affiliate which is a member of an acceptable Medallion Signature Guarantee Program. The corresponding affiliate will arrange for the signature to be over-guaranteed. 

REASON FOR TRANSFER – FOR US RESIDENTS ONLY 

Consistent with US IRS regulations, Computershare 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).
