stock exchange on which the Common Shares are principally traded, equals or exceeds $3.00 for 20 consecutive Trading Days, the Corporation shall be entitled, at the option of the Corporation, to exercise the Acceleration Right by delivering an
Acceleration Notice to the Warrantholders within five (5) Business Days. An Acceleration Notice shall be delivered to each Warrantholder in the manner in Section 10.1. Upon the Corporation’s exercise of the Acceleration Right the
Corporation shall issue a press release to the effect that the Warrants will expire at 5:00 p.m. (Toronto time) on the date specified in the Acceleration Notice.

	2.3	Warrantholder not a Shareholder 

 Except as may be specifically provided herein, nothing
in this Indenture or in the holding of a Warrant Certificate, entitlement to a Warrant or otherwise, shall, in itself, confer or be construed as conferring upon a Warrantholder any right or interest whatsoever as a Shareholder, including, but not
limited to, the right to vote at, to receive notice of, or to attend, meetings of Shareholders or any other proceedings of the Corporation, or the right to Dividends and other allocations. 

 

	2.4	Warrants to Rank Pari Passu 

 All Warrants shall rank equally and without preference over
each other, whatever may be the actual date of issue thereof. 
  

	2.5	Form of Warrants, Certificated Warrants 

 The Warrants may be issued in both certificated
and uncertificated form. Each Put Unit Warrant will be evidenced in certificated form only and bear the applicable legends as set forth in Schedule “A” hereto. All Warrants issued in certificated form shall be evidenced by a Warrant
Certificate (including all replacements issued in accordance with this Indenture), substantially in the form set out in Schedule “A” hereto, which shall be dated as of the Issue Date, shall bear such 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. 
  

	2.6	Book Entry Only Warrants 

  

	 	(a)	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
Warrants except where physical certificates evidencing ownership in such securities are required or as set out herein or as may be requested by the Depository, as determined by the Corporation, from time to time. Except as provided in this
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 having any legend set forth in Section 2.8 herein and 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 accordance with the internal procedures of the Warrant Agent. 


  
 - 12 - 









	 	(b)	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 any 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: 

  

	 	(i)	the Depository notifies the Corporation that it is unwilling or unable to continue to act as depository in connection with the Book Entry Only Warrants and the Corporation is unable to locate a qualified successor;


  

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

  

	 	(iii)	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; 


 

	 	(iv)	the Corporation determines that the Warrants shall no longer be held as Book Entry Only Warrants through the Depository; 

  

	 	(v)	such right is required by Applicable Law, as determined by the Corporation and the Corporation’s Counsel; 

  

	 	(vi)	the Warrant is to be Authenticated to or for the account or benefit of a person in the United States or a U.S. Person; or 

  

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


following which, Warrants for those holders requesting the same shall be registered and issued to the beneficial owners of such Warrants or
their nominees as directed by the holder. The Corporation shall provide an Officer’s Certificate giving notice to the Warrant Agent of the occurrence of any event outlined in this Section 2.6 (2)(a)—(f). 

 

	 	(c)	Subject to the provisions of this Section 2.6, any exchange of CDS Global Warrants for Warrants which are not CDS Global Warrants may be made in whole or in part in accordance with the provisions of
Section 2.11, mutatis mutandis. All such Warrants issued in exchange for a CDS Global Warrant or any portion thereof shall be registered in such names as the Depository for such CDS Global Warrants shall direct and shall be entitled to
the same benefits and subject to the same terms and conditions (except insofar as they relate specifically to CDS Global Warrants) as the CDS Global Warrants or portion thereof surrendered upon such exchange. 


 

	 	(d)	Every Warrant that is Authenticated upon registration or transfer of a CDS Global Warrant, or in exchange for or in lieu of a CDS Global Warrant or any portion thereof, whether pursuant to this Section 2.6, or
otherwise, shall be Authenticated in the form of, and shall be, a CDS Global Warrant, unless such Warrant is registered in the name of a person other than the Depository for such CDS Global Warrant or a nominee thereof. 


 

	 	(e)	Notwithstanding anything to the contrary in this Indenture, subject to Applicable Law, the CDS Global Warrant will be issued as an Uncertificated Warrant, unless otherwise requested in writing by the Depository or the
Corporation. 

  

	 	(f)	 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 Only Participants and between such Book Entry Only Participants and the




  
 - 13 - 









	 	
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 Only
Participant in accordance with the rules and procedures of the Depository. 

  

	 	(g)	Notwithstanding anything herein to the contrary, neither the Corporation nor the Warrant Agent nor any agent thereof shall have any responsibility or liability for: 


 

	 	(i)	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); 


 

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


 

	 	(iii)	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 Only Participant. 

  

	 	(h)	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. 

  

	2.7	Warrant Certificate 

  

	 	(a)	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, subject to the consent of the Corporation. Each Warrant Certificate shall be Authenticated manually on behalf of the Warrant Agent. Each Warrant Certificate shall be signed by any two duly authorized signatories of the Corporation;
whose signature shall appear on the Warrant Certificate and may be printed, lithographed or otherwise mechanically reproduced thereon and, in such event, certificates so signed are as valid and binding upon the Corporation as if it had been signed
manually. Any Warrant Certificate which has two signatures as hereinbefore provided shall be valid notwithstanding that one or more of the persons 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. 


 

	 	(b)	 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




  
 - 14 - 









	 	
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. 


 

	 	(c)	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 the number of Common Shares set out in such Warrant Certificate in accordance with the terms hereof, notwithstanding that the form of such Warrant Certificate may not be in the form currently required by this Indenture.


  

	 	(d)	No Warrant shall be considered issued and shall be valid or obligatory or shall entitle the holder thereof to the benefits of this Indenture, until it has been Authenticated by the Warrant Agent. Authentication by the
Warrant Agent, including by way of entry on the register, shall not be construed as a representation or warranty by the Warrant Agent as to the validity of this Indenture or of such Warrant Certificates or Uncertificated Warrants (except the due
Authentication thereof) or as to the performance by the Corporation of its obligations under this Indenture and the Warrant Agent shall in no respect be liable or answerable for the use made of the Warrants or any of them or of the consideration
thereof. Authentication by the Warrant Agent shall be conclusive evidence as against the Corporation that the Warrants so Authenticated have been duly issued hereunder and that the holder thereof is entitled to the benefits of this Indenture.


  

	 	(e)	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
manual 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. 

  

	 	(f)	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. 

  

	 	(g)	The Authentication by the Warrant Agent of any Warrants whether by way of entry on the register or otherwise shall not be construed as a representation or warranty by the Warrant Agent as to the validity of the
Indenture or 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.

	2.8	Legends 

  

	 	(a)	Each Warrant Certificate evidencing a Put Option Warrant and each Warrant Certificate issued in exchange therefor or in substitution thereof shall bear or be deemed to bear the following legends or such variations
thereof as the Corporation may prescribe from time to time: 

 “THESE WARRANTS AND THE SECURITIES DELIVERABLE UPON THE
EXERCISE THEREOF HAVE NOT BEEN AND WILL NOT BE REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “U.S. SECURITIES ACT”). THESE SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY
(A) TO THE CORPORATION, (B) IF THE SECURITIES HAVE BEEN REGISTERED IN COMPLIANCE WITH THE REGISTRATION REQUIREMENTS UNDER THE U.S. SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS (C) IN COMPLIANCE WITH THE
EXEMPTION FROM THE REGISTRATION REQUIREMENTS UNDER THE U.S. SECURITIES ACT IN ACCORDANCE WITH RULE 144 THEREUNDER, IF APPLICABLE, AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS, OR (D) IN A TRANSACTION THAT DOES NOT REQUIRE
REGISTRATION UNDER THE U.S. SECURITIES ACT OR ANY APPLICABLE STATE LAWS AND REGULATIONS GOVERNING THE OFFER AND SALE OF SECURITIES, AND THE HOLDER HAS, PRIOR TO SUCH SALE, FURNISHED TO THE CORPORATION AN OPINION OF COUNSEL OF RECOGNIZED STANDING, OR
OTHER EVIDENCE OF EXEMPTION, REASONABLY SATISFACTORY TO THE CORPORATION. HEDGING TRANSACTIONS INVOLVING THE SECURITIES REPRESENTED HEREBY MAY NOT BE CONDUCTED UNLESS IN COMPLIANCE WITH U.S. SECURITIES LAWS. 

THE SECURITIES EVIDENCED HEREBY AND THE SECURITIES ISSUABLE UPON EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OR U.S.
STATE SECURITIES LAWS. THESE WARRANTS MAY NOT BE EXERCISED IN THE UNITED STATES OR BY OR ON BEHALF OF, OR FOR THE ACCOUNT OR BENEFIT OF, A U.S. PERSON UNLESS THIS SECURITY AND THE COMMON SHARES ISSUABLE UPON EXERCISE OF THIS SECURITY HAVE BEEN
REGISTERED UNDER THE U.S. SECURITIES ACT AND THE APPLICABLE STATE SECURITIES LEGISLATION OR AN EXEMPTION FROM SUCH REGISTRATION REQUIREMENTS IS AVAILABLE. “UNITED STATES” AND “U.S. PERSON” ARE AS DEFINED BY REGULATION S UNDER THE
U.S. SECURITIES ACT.”; 
 The Warrant Agent shall be entitled to request any other documents that it may require in accordance with its
internal policies for the removal of the legend set forth above. 
  

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

 “UNLESS THIS
CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF CDS CLEARING AND DEPOSITORY SEVICES INC. (“CDS”) TO COHBAR, INC. (THE “ISSUER”) OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE
ISSUED IN RESPECT THEREOF IS REGISTERED IN THE NAME OF CDS & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN 

  
 - 16 - 








 
AUTHORIZED REPRESENTATIVE OF CDS (AND ANY PAYMENT IS MADE TO CDS & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF CDS), ANY TRANSFER, PLEDGE OR OTHER USE
HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED HOLDER HEREOF, CDS & CO., HAS A PROPERTY INTEREST IN THE SECURITIES REPRESENTED BY THIS CERTIFICATE HEREIN AND IT IS A VIOLATION OF ITS RIGHTS FOR ANOTHER
PERSON TO HOLD, TRANSFER OR DEAL WITH THIS CERTIFICATE.” 
  

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

  

	2.9	Register of Warrants 

  

	 	(a)	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): 


 

	 	(i)	the name and address of the holder of the Warrants, the date of Authentication thereof and the number of Warrants; 

  

	 	(ii)	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; 

  

	 	(iii)	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. 

 

	 	(b)	 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 



  
 - 17 - 








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

 

	2.10	Issue in Substitution for Warrant Certificates Lost, etc. 

  

	 	(a)	If any Warrant Certificate becomes mutilated or is lost, destroyed or stolen, the Corporation, subject to applicable law, shall issue and thereupon the Warrant Agent shall certify and deliver, a new Warrant Certificate
of like tenor, and bearing the same legend, if applicable, as the one mutilated, lost, destroyed or stolen in exchange for and in place of and upon cancellation of such mutilated Warrant Certificate, or in lieu of and in substitution for such lost,
destroyed or stolen Warrant Certificate, and the substituted Warrant Certificate shall be in a form approved by the Warrant Agent and the Warrants evidenced thereby shall be entitled to the benefits hereof and shall rank equally in accordance with
its terms with all other Warrants issued or to be issued hereunder. 

  

	 	(b)	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. 

  

	2.11	Exchange of Warrant Certificates 

  

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


 

	 	(b)	Warrant Certificates may be exchanged only at the Warrant Agency or at any other place that is designated by the Corporation with the approval of the Warrant Agent. Any Warrant Certificate from the holder (or such other
instructions, in form satisfactory to the Warrant Agent), tendered for exchange shall be surrendered to the Warrant Agency and cancelled by the Warrant Agent. 


  
 - 18 - 









	 	(c)	Warrant Certificates exchanged for Warrant Certificates that bear the legend set forth in Section 2.8(a) shall bear the same legend. 


 

	2.12	Transfer and Ownership of Warrants 

  

	 	(a)	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 :“B” and (b) in the case of Book Entry Only Warrants, in accordance with procedures prescribed by the Depository under the book entry registration system, and (c) upon compliance
with: 

  

	 	(i)	the conditions herein; 

  

	 	(ii)	such reasonable requirements as the Warrant Agent may prescribe; and 

  

	 	(iii)	all applicable securities legislation and requirements of regulatory authorities; 

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

 

	 	(b)	If a Warrant Certificate tendered for transfer bears the legend set forth in Section 2.8(a), the Warrant Agent shall not register such transfer unless the transferor has provided the Warrant Agent with the Warrant
Certificate and (A) the transfer is made to the Corporation or (B) a declaration to the effect set forth in Schedule “B” to this Warrant Indenture, or in such other form as the Corporation may from time to time prescribe, is
delivered to the Warrant Agent, and if required by the Warrant Agent, the transferor provides an opinion of counsel of recognized standing, reasonably satisfactory to the Corporation and the Warrant Agent that the transfer is in compliance with
applicable state laws and the U.S. Securities Act. 

  

	 	(c)	Subject to the provisions of this Indenture, Applicable Legislation and applicable law, the Warrantholder shall be entitled to the rights and privileges attaching to the Warrants, and the issue of 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. 


  
 - 19 - 









	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 
  

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

 

	3.2	Warrant Exercise 

  

	 	(a)	Registered holders of Warrant Certificates who wish to exercise the 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 “C”, which may be amended by the Corporation with the consent of the Warrant Agent, if such amendment does not, in the reasonable opinion of the Corporation and the Warrant
Agent, which may be based on the advice of Counsel, materially and adversely affect the rights, entitlements and interests of the Warrantholders, and deliver such certificate(s), the executed Exercise Notice and a certified cheque, bank draft or
money order payable to or to the order of the Corporation for the aggregate Exercise Price to the Warrant Agent at the Warrant Agency. The Warrants represented by a Warrant Certificate shall be deemed to be surrendered upon personal delivery of such
certificate, Exercise Notice and aggregate Exercise Price or, if such documents are sent by mail or other means of transmission, upon actual receipt thereof by the Warrant Agent at the office referred to above. 


 

	 	(b)	A Registered holder of Uncertificated Warrants evidenced by a security entitlement in respect of Warrants must complete the Exercise Notice and deliver the executed Exercise Notice and a certified cheque, bank draft or
money order payable to or to the order of the Corporation for the aggregate Exercise Price to the Warrant Agent at the Warrant Agency. The Uncertificated Warrants shall be deemed to be surrendered upon receipt of the Exercise Notice and aggregate
Exercise Price or, if such documents are sent by mail or other means of transmission, upon actual receipt thereof by the Warrant Agent at the office referred to above. 


 

	 	(c)	 A beneficial owner of Uncertificated Warrants who desires to exercise his, her or its Warrants must do so by causing a Book Entry Only 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
aggregate Exercise Price, the Depository shall deliver to the Warrant Agent confirmation of its intention to exercise 



  
 - 20 - 








 
Warrants (a “Confirmation”) in a manner acceptable to the Warrant Agent, including by electronic means through a book based registration system. If the Book Entry Only Participant is
not able to make or deliver the foregoing representation by initiating the electronic exercise of the Warrants, then such Warrants shall be withdrawn from the book based registration system, by the Book Entry Only Participant and an individually
registered Warrant Certificate shall be issued by the Warrant Agent to such Beneficial Owner or Book Entry Only Participant and the exercise procedures set forth in Section 3.2(a) shall be followed. 

 

	 	(d)	Payment representing the aggregate Exercise Price must be provided to the appropriate office of the Book Entry Only Participant in a manner acceptable to it. A notice in form acceptable to the Book Entry Only
Participant and payment from such beneficial holder should be provided to the Book Entry Only Participant sufficiently in advance so as to permit the Book Entry Only 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 Expiry Time. The Depository will initiate the exercise by way of the Confirmation and forward the aggregate Exercise Price electronically to the Warrant Agent and the
Warrant Agent will execute the exercise by issuing to 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 Only Participant exercising the Warrants on its behalf. 

  

	 	(e)	By causing a Book Entry Only 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 Only
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. 


 

	 	(f)	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 Only 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 Only Participant or the Warrantholder. 

  

	 	(g)	Any exercise form or 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 form need not be executed by the Depository. 


 

	 	(h)	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. 


  
 - 21 - 









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

  

	 	(j)	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. 


 

	 	(k)	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 Time will be deemed to have been received by the Warrant Agent on the next following Business Day. 


 

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

  

	3.3	Prohibition on Exercise by U.S. Persons; Legended Certificates; Special Conditions to Exercise of Put Unit Warrants. 

  

	 	(a)	If the issuance of Common Shares upon the exercise of any Warrants requires the maintenance of an effective Registration Statement under the U.S. Securities Act with respect to such Common Shares, then in no event shall
such Common Shares be issued except pursuant to an effective Registration Statement under the U.S. Securities Act and the Corporation causes to be delivered to the holder a U.S. Prospectus; provided however, that in the absence of an effective
Registration Statement, subject to applicable law, a holder of any Warrant may: 

  

	 	(i)	exercise such Warrants, if the holder is not a U.S. Purchaser and the holder delivers a duly completed and executed Warrant Exercise Certification certifying that the holder: (A)(1) is not in the United States;
(2) is not a U.S. Person and is not exercising the Warrants for, or on behalf or benefit of, a U.S. Person or person in the United States; (3) did not execute or deliver the Warrant Exercise Notice in the United States; (4) agrees not
to engage in hedging transactions with regard to the Securities prior to the expiration of the one year distribution compliance period set forth in Rule 903(b)(3) of Regulation S; (5) acknowledges that the Common Shares issuable upon exercise
of the Warrants are “restricted securities” as defined in Rule 144 of the U.S. Securities Act and upon the issuance thereof, and until such time as the same is no longer required under the applicable requirements of the U.S. Securities Act
or applicable U.S. state laws and regulations, the certificates representing the Common Shares will bear a restrictive legend; and (6) acknowledges that the Corporation shall refuse to register any transfer of any securities not made pursuant
to an effective Registration Statement under the U.S. Securities Act, or pursuant to an available exemption from registration under the U.S. Securities Act; and (B) neither the holder nor any affiliate of the holder or other person acting on
the holder’s behalf has engaged in any “directed selling efforts” (as defined in Regulation S) in the United States; or 


  
 - 22 - 









	 	(ii)	exercise such Warrants in a transaction that does not require registration under the U.S. Securities Act or any applicable U.S. state laws and regulations and the holder has (A) delivered a duly completed and
executed Warrant Exercise Certification certifying that the holder is exercising the Warrants pursuant to such exemptions and (B) furnished to the Corporation, prior to such exercise, an opinion of counsel of recognized standing in form and
substance satisfactory to the Corporation to such effect. 

  

	 	(b)	Section 3.3(a) notwithstanding, Put Unit Warrants which bear the legend set forth in Section 2.8(a) may be exercised in the United States by or on behalf of a U.S. Person, and Common Shares issued upon
exercise of any such Warrants may be delivered to an address in the United States, provided that the holder delivers a duly completed and executed Warrant Exercise Certification certifying that the holder (a) is the original purchaser of the
Warrants pursuant to the Corporation’s exercise of its rights pursuant to a certain Put Agreement between the undersigned and the Corporation (the “Put Agreement”), (b) is exercising the Warrants for its own account,
(c) is an “accredited investor” as defined in Rule 501(a) of Regulation D under the U.S. Securities Act at the time of exercise of these Warrants, and (d) the representations and warranties of the holder made in the original Put
Agreement remain true and correct as of the date of exercise of the Warrants. 

  

	 	(c)	Unless the Warrant is exercised pursuant to an effective Registration Statement the certificate representing the Common Shares issued upon exercise of the Warrant will bear a legend substantially in the form set forth
below: 

 THESE SECURITIES HAVE NOT BEEN AND WILL NOT BE REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED
(THE “U.S. SECURITIES ACT”). THESE SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY (A) TO THE CORPORATION, (B) IF THE SECURITIES HAVE BEEN REGISTERED IN COMPLIANCE WITH THE REGISTRATION REQUIREMENTS
UNDER THE U.S. SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS (C) IN COMPLIANCE WITH THE EXEMPTION FROM THE REGISTRATION REQUIREMENTS UNDER THE U.S. SECURITIES ACT IN ACCORDANCE WITH RULE 144 THEREUNDER, IF APPLICABLE,
AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS, OR (D) IN A TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE U.S. SECURITIES ACT OR ANY APPLICABLE STATE LAWS AND REGULATIONS GOVERNING THE OFFER AND SALE OF SECURITIES, AND THE
HOLDER HAS, PRIOR TO SUCH SALE, FURNISHED TO THE CORPORATION AN OPINION OF COUNSEL OF RECOGNIZED STANDING, OR OTHER EVIDENCE OF EXEMPTION, REASONABLY SATISFACTORY TO THE CORPORATION. HEDGING TRANSACTIONS INVOLVING THE SECURITIES REPRESENTED HEREBY
MAY NOT BE CONDUCTED UNLESS IN COMPLIANCE WITH U.S. SECURITIES LAWS. 
  

	 	(d)	 If issuance of Common Shares upon the exercise of any Warrant requires the maintenance of an effective Registration Statement under the U.S.
Securities Act with respect to such Common Shares then the Corporation shall have the authority to suspend the exercise of any such Warrants while such registration statement is not effective. Similarly, a Warrantholder residing in a state where a
required registration or 



  
 - 23 - 









	 	
governmental approval of issuance of the Common Shares is not in effect as of or has not been obtained within a reasonable time after the surrender date of the Warrant Certificate for exercise
shall not be entitled to exercise Warrants, unless in the opinion of counsel to the Corporation such registration or approval in such state shall not be required or the Corporation otherwise authorizes the issuance. In such event, the Warrantholder
shall be entitled to transfer the Warrants to others, but only prior to the Expiry Time for the Warrants being transferred. If no Registration Statement is effective at any time when any Warrant is exercised, such Warrantholder shall be notified
forthwith by the Warrant Agent that such Warrantholder is entitled, at his or her option, to exercise the Warrant only in accordance with the conditions set forth in Sections 3.3(a)(i)-(ii) or 3.3(b) and upon delivery of a Warrant Exercise
Certification to the Warrant Agent and the Corporation. 

  

	 	(e)	Notwithstanding that the Corporation may not have maintained a current Registration Statement in respect of Common Shares under the U.S. Securities Act, no Warrantholder (whether a U.S. Purchaser or otherwise) shall
have any right to receive, and the Corporation shall be under no obligation to pay to any Warrantholder (whether a U.S. Purchaser or otherwise), any cash amount or other consideration or compensation upon exercise of the Warrants, other than as
expressly provided by this Warrant Indenture, and the Corporation shall not be under any obligation to redeem or otherwise purchase any Warrants in any circumstance; provided, however, that nothing in this clause shall limit or restrict any remedies
of the Warrant Agent or any Warrantholder or Warrantholders in respect of a breach by the Corporation of a representation, warranty or covenant hereunder. 

  

	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. 

 

	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. Copies of the Warrant register shall also be kept at such other place or places, if any, as the Corporation, with the approval of the Warrant Agent, may designate. The Warrant Agent will from time to time when
requested to do so by the Corporation or any Registered Warrantholder, upon payment of the Warrant Agent’s reasonable charges, furnish a list of the names and addresses of Registered Warrantholders showing the number of Warrants held by each
such Registered Warrantholder. 

  
 - 24 - 









	3.6	Effect of Exercise of Warrant Certificates 

  

	 	(a)	Upon the exercise of Warrant Certificates 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 five Business Days of the Exercise Date unless the register 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 register is
reopened. It is hereby understood that in order for persons to whom Common Shares are to be issued, to become holders of Common Shares on record on the Exercise Date, beneficial holders must commence the exercise process sufficiently in advance so
that the Warrant Agent is in receipt of all items of exercise at least one Business Day prior to such Exercise Date. 

  

	 	(b)	Within five Business Days after the Exercise Date with respect to a Warrant, the Warrant Agent shall 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. 


 

	3.7	Partial Exercise of Warrants; Fractions 

  

	 	(a)	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. 

  

	 	(b)	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. 

  

	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. 

 

	3.9	Accounting and Recording 

  

	 	(a)	The Warrant Agent shall promptly account to the Corporation with respect to Warrants exercised, and shall promptly forward to the Corporation (or into an account or accounts of the Corporation with the bank or trust
company designated by the Corporation for that 


  
 - 25 - 









	 	
purpose), all monies received by the Warrant Agent on the subscription of Common Shares through the exercise of Warrants. All such monies and any securities or other instruments, from time to
time received by the Warrant Agent, shall be received in trust for, and shall be segregated and kept apart by the Warrant Agent, the Warrantholders and the Corporation as their interests may appear in the register maintained by the Warrant Agent.


  

	 	(b)	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. 


 

	3.10	Securities Restrictions 

 Notwithstanding anything herein contained, Common Shares will
be issued upon exercise of a Warrant only in compliance with the securities laws of any applicable jurisdiction. 
 ARTICLE 4 

ADJUSTMENT OF NUMBER OF COMMON SHARES 

AND EXERCISE PRICE 
  

	4.1	Adjustment of Number of Common Shares and Exercise Price 

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

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

  

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

  

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

  

	 	(iii)	issue Common Shares or securities exchangeable for, or convertible into, Common Shares to all or substantially all of the holders of Common Shares by way of stock dividend or other distribution (other than a
distribution of Common Shares upon the exercise of Warrants or any outstanding options); 

 (any of such events in
Section 4.1(a) (i), (ii) or (iii) being called a “Common Share Reorganization”) then the Exercise Price as of the effective date or record date of such Common Share Reorganization shall in the case of the events referred to
in (i) or (iii) above be decreased in proportion to the number of outstanding Common Shares resulting from such subdivision, re-division, change or distribution, or shall, in the case of the events referred to in (ii) above, be
increased in proportion to the number of outstanding Common Shares resulting from such reduction, combination or consolidation by multiplying the Exercise Price in effect immediately prior to such effective date or record date by a fraction, the
numerator of which shall be the number of Common Shares outstanding on such effective date or record date before giving effect to such Common Share Reorganization and the denominator of which shall be the number of Common


  
 - 26 - 








 
Shares outstanding as of the effective date or record date after giving effect to such Common Shares Reorganization (including, in the case where securities exchangeable for or convertible into
Common Shares are distributed, the number of Common Share that would have been outstanding had such securities been exchanged for or converted into Common Shares on such record date or effective date). Such adjustment shall be made successively
whenever any Common Share Reorganization shall occur. Upon any adjustment of the Exercise Price pursuant to Section 4.1(a), the Exchange Rate shall be contemporaneously adjusted by multiplying the number of Common Shares theretofore obtainable
on the exercise thereof by a fraction of which the numerator shall be the Exercise Price in effect immediately prior to such adjustment and the denominator shall be the Exercise Price resulting from such adjustment; 

 

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

  

	 	(c)	 if and whenever at any time during the Adjustment Period the Corporation shall fix a record date for the making of a distribution to all or
substantially all the holders of its outstanding Common Shares of (i) securities of any class, whether of the Corporation or 



  
 - 27 - 









	 	
any other trust (other than Common Shares), (ii) rights, options or warrants to subscribe for or purchase Common Shares (or other securities convertible into or exchangeable for Common
Shares), other than pursuant to a Rights Offering; (iii) evidences of its indebtedness or (iv) any property or other assets then, in each such case, the Exercise Price shall be adjusted immediately after such record date so that it shall
equal the price determined by multiplying the Exercise Price in effect on such record date by a fraction, of which the numerator shall be the total number of Common Shares outstanding on such record date multiplied by the Current Market Price on
such record date, less the excess, if any, of the fair market value on such record date, as determined by the Corporation (whose determination shall be conclusive), of such securities or other assets so issued or distributed over the fair market
value of any consideration received therefor by the Corporation from the holders of the Common Shares, and of which the denominator shall be the total number of Common Shares outstanding on such record date multiplied by the Current Market Price;
and Common Shares owned by or held for the account of the Corporation shall be deemed not to be outstanding for the purpose of any such computation; such adjustment shall be made successively whenever such a record date is fixed; to the extent that
such distribution is not so made, the Exercise Price shall be readjusted to the Exercise Price which would then be in effect if such record date had not been fixed. Upon any adjustment of the Exercise Price pursuant to this Section 4.1(c), the
Exchange Rate will be adjusted immediately after such record date so that it will equal the rate determined by multiplying the Exchange Rate in effect on such record date by a fraction, of which the numerator shall be the Exercise Price in effect
immediately prior to such adjustment and the denominator shall be the Exercise Price resulting from such adjustment; 

  

	 	(d)	 if and whenever at any time during the Adjustment Period, there is a reclassification of the Common Shares or a capital reorganization of the
Corporation other than as described in Section 4.1(a) or a consolidation, amalgamation, arrangement or merger of the Corporation with or into any other body corporate, trust, partnership or other entity, or a sale or conveyance of the property
and assets of the Corporation as an entirety or substantially as an entirety to any other body corporate, trust, partnership or other entity, any Registered Warrantholder who has not exercised its right of acquisition prior to the effective date of
such reclassification, capital reorganization, consolidation, amalgamation, arrangement or merger, sale or conveyance, upon the exercise of such right thereafter, shall be entitled to receive upon payment of the Exercise Price and shall accept, in
lieu of the number of Common Shares that prior to such effective date the Registered Warrantholder would have been entitled to receive, the number of shares or other securities or property of the Corporation or of the body corporate, trust,
partnership or other entity resulting from such merger, amalgamation or consolidation, or to which such sale or conveyance may be made, as the case may be, that such Registered Warrantholder would have been entitled to receive on such
reclassification, capital reorganization, consolidation, amalgamation, arrangement or merger, sale or conveyance, if, on the effective date thereof, as the case may be, the Registered Warrantholder had been the registered holder of the number of
Common Shares to which prior to such effective date it was entitled to acquire upon the exercise of the Warrants. If determined appropriate by the Warrant Agent, relying on advice of Counsel, to give effect to or to evidence the provisions of this
Section 4.1(d), the Corporation, its successor, or such purchasing body corporate, partnership, trust or other entity, as the case may be, shall, prior to or contemporaneously with any such reclassification, capital reorganization,
consolidation, amalgamation, arrangement, merger, sale or conveyance, enter into an indenture which shall provide, to the extent possible, for the application of the provisions 



  
 - 28 - 









	 	
set forth in this Indenture with respect to the rights and interests thereafter of the Registered Warrantholders to the end that the provisions set forth in this Indenture shall thereafter
correspondingly be made applicable, as nearly as may reasonably be, with respect to any shares, other securities or property to which a Registered Warrantholder is entitled on the exercise of its acquisition rights thereafter. Any indenture entered
into between the Corporation and the Warrant Agent pursuant to the provisions of this Section 4.1(d) shall be a supplemental indenture entered into pursuant to the provisions of Article 8 hereof. Any indenture entered into between the
Corporation, any successor to the Corporation or such purchasing body corporate, partnership, trust or other entity and the Warrant Agent shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments
provided in this Section 4.1 and which shall apply to successive reclassifications, capital reorganizations, amalgamations, consolidations, mergers, sales or conveyances; 


 

	 	(e)	in any case in which this Section 4.1 shall require that an adjustment shall become effective immediately after a record date for an event referred to herein, the Corporation may defer, until the occurrence of such
event, issuing to the Registered Warrantholder of any Warrant exercised after the record date and prior to completion of such event the additional Common Shares issuable by reason of the adjustment required by such event before giving effect to such
adjustment; provided, however, that the Corporation shall deliver to such Registered Warrantholder an appropriate instrument evidencing such Registered Warrantholder’s right to receive such additional Common Shares upon the occurrence of the
event requiring such adjustment and the right to receive any distributions made on such additional Common Shares declared in favour of holders of record of Common Shares on and after the relevant date of exercise or such later date as such
Registered Warrantholder would, but for the provisions of this Section 4.1(e), have become the holder of record of such additional Common Shares pursuant to Section 4.1; 


 

	 	(f)	in any case in which Section 4.1(a)(iii), Section 4.1(b) or Section 4.1(c) require that an adjustment be made to the Exercise Price, no such adjustment shall be made if the Registered Warrantholders of
the outstanding Warrants receive, subject to any required stock exchange or regulatory approval, the rights or warrants referred to in Section 4.1(a)(iii), Section 4.1(b) or the shares, rights, options, warrants, evidences of indebtedness
or assets referred to in Section 4.1(c), as the case may be, in such kind and number as they would have received if they had been holders of Common Shares on the applicable record date or effective date, as the case may be, by virtue of their
outstanding Warrant having then been exercised into Common Shares at the Exercise Price in effect on the applicable record date or effective date, as the case may be; 


 

	 	(g)	the adjustments provided for in this Section 4.1 are cumulative, and shall, in the case of adjustments to the Exercise Price be computed to the nearest whole cent and shall apply to successive subdivisions,
re-divisions, reductions, combinations, consolidations, distributions, issues or other events resulting in any adjustment under the provisions of this Section 4.1, provided that, notwithstanding any other provision of this Section, no
adjustment of the Exercise Price shall be required unless such adjustment would require an increase or decrease of at least 1% in the Exercise Price then in effect; provided, however, that any adjustments which by reason of this Section 4.1(g)
are not required to be made shall be carried forward and taken into account in any subsequent adjustment; and 


  
 - 29 - 









	 	(h)	after any adjustment pursuant to this Section 4.1, the term “Common Shares” where used in this Indenture shall be interpreted to mean securities of any class or classes which, as a result of such
adjustment and all prior adjustments pursuant to this Section 4.1, the Registered Warrantholder is entitled to receive upon the exercise of his Warrant, and the number of Common Shares indicated by any exercise made pursuant to a Warrant shall
be interpreted to mean the number of Common Shares or other property or securities a Registered Warrantholder is entitled to receive, as a result of such adjustment and all prior adjustments pursuant to this Section 4.1, upon the full exercise
of a Warrant. 

  

	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. 
  

	4.3	No Adjustment for Certain Transactions 

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

 

	4.4	Determination by Independent Firm 

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

	4.5	Proceedings Prior to any Action Requiring Adjustment 

 As a condition precedent to the
taking of any action which would require an adjustment in any of the acquisition rights pursuant to any of the Warrants, including the number of 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. 
  

	4.6	Certificate of Adjustment 

 The Corporation shall from time to time immediately after the
occurrence of any event which requires an adjustment or readjustment as provided in Section 4.1, deliver a certificate of the Corporation to the Warrant Agent specifying the nature of the event requiring the same and the amount of the
adjustment or readjustment necessitated thereby and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based, which certificate shall be supported by a


  
 - 30 - 








 
certificate of the Corporation’s Auditors verifying such calculation. The Warrant Agent shall act and 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. 
  

	4.7	Notice of Special Matters 

 The Corporation covenants with the Warrant Agent that, so
long as any Warrant remains outstanding, it will give notice to the Warrant Agent and to the Registered Warrantholders of its intention to fix a record date that is prior to the Expiry Time 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. 

 

	4.8	No Action after Notice 

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

	4.9	Other Action 

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

 

	4.10	Protection of Warrant Agent 

 The Warrant Agent shall not: 

 

	 	(a)	at any time be under any duty or responsibility to any Registered Warrantholder to determine whether any facts exist which may require any adjustment contemplated by Section 4.1, or with respect to the nature or
extent of any such adjustment when made, or with respect to the method employed in making the same; 

  

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


  
 - 31 - 









	 	(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. 

  

	4.11	Participation by Warrantholder 

 No adjustments shall be made pursuant to this Article 4
if the Registered Warrantholders are entitled to participate in any event described in this Article 4 on the same terms, mutatis mutandis, as if the Registered Warrantholders had exercised their Warrants prior to, or on the effective date or record
date of, such event. 
 ARTICLE 5 

RIGHTS OF THE CORPORATION AND COVENANTS 
  

	5.1	Optional Purchases by the Corporation 

 Subject to compliance with applicable securities
legislation and approval of applicable regulatory authorities, if any, the Corporation may from time to time purchase by private contract or otherwise any of the Warrants. Any such purchase shall be made at the lowest price or prices at which, in
the opinion of the directors, 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. 
  

	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; 


 

	 	(c)	all Common Shares which shall be issued upon exercise of the right to acquire provided for herein shall be fully paid and non-assessable; 


 

	 	(d)	it will use reasonable commercial efforts to maintain its existence;

	 	(g)	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 (c) any action taken, suffered, or omitted by it or for any error of judgement made by the Warrant Agent in the

	9.8	Replacement of Warrant Agent; Successor by Merger 

  

	 	(a)	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 a judge of a court of the Province of British
Columbia on such notice as such judge may direct, for the appointment of a new warrant agent; but any new warrant agent so appointed by the 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 each of the provinces of Canada. 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. 

  

	 	(b)	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. 


 

	 	(c)	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. 


 

	 	(d)	Any corporation into 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). 

  

	9.9	Conflict of Interest 

  

	 	(a)	The Warrant Agent represents 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 90 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. 


  
 - 44 - 









	 	(b)	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. 

  

	9.10	Acceptance of Agency 

 The Warrant Agent hereby accepts the agency in this Indenture
declared and provided for and agrees to perform the same upon the terms and conditions herein set forth. 
  

	9.11	Warrant Agent Not to be Appointed Receiver 

 The Warrant Agent and any person related to
the Warrant Agent shall not be appointed a receiver, a receiver and manager or liquidator of all or any part of the assets or undertaking of the Corporation. 
  

	9.12	Warrant Agent Not Required to Give Notice of Default 

 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. 
  

	9.13	Anti-Money Laundering 

  

	 	(a)	Each party to this Agreement 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 Agreement, 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. 

  

	 	(b)	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 Agreement 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 Agreement, 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. 


  
 - 45 - 









	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: 
  

	 	(a)	to provide the services required under this Indenture and other services that may be requested from time to time; 

  

	 	(b)	to help the Warrant Agent manage its servicing relationships with such individuals; 

  

	 	(c)	to meet the Warrant Agent’s legal and regulatory requirements; and 

  

	 	(d)	if Social Insurance Numbers are collected by the Warrant Agent, to perform tax reporting and to assist in verification of an individual’s identity for security 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 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. 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. 
  

	9.15	Securities Exchange Commission Certification 

  

	 	(a)	Currently reporting: 

 The Corporation confirms that it has either (i) a class of
securities registered pursuant to Section 12 of the US Securities Exchange Act of 1934, as amended (the “Act”); or (ii) a reporting obligation pursuant to Section 15(d) of the Act. The Corporation covenants that in the event
that any such registration or reporting obligation shall be terminated by the Corporation in accordance with the 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 United States SEC obligations with respect to those clients who are filing with the SEC.

take notice by statute or by order of a court of competent jurisdiction. The receipt of any such Registered Warrantholder of the Common Shares which may be acquired pursuant thereto shall be a good discharge to the Corporation and the Warrant Agent

effect and the Warrant Agent, on demand of and at the cost and expense of the Corporation and upon delivery to the Warrant Agent of a certificate of the Corporation stating that all conditions
precedent to the satisfaction and discharge of this Indenture have been complied with, shall execute proper instruments acknowledging satisfaction of and discharging this Indenture. Notwithstanding the foregoing, the indemnities provided to the

	10.6	Provisions of Indenture and Warrants for the Sole Benefit of Parties and Registered Warrantholders 


Nothing in this Indenture or in the Warrants, expressed or implied, shall give or be construed to give to any person other than the parties
hereto and the Registered Warrantholders, as the case may be, any legal or equitable right, remedy or claim under this Indenture, or under any covenant or provision herein or therein contained, all such covenants and provisions being for the sole

remaining provisions of this Indenture and without affecting the validity or enforceability of such provision in any other jurisdiction or without affecting its application to other parties or circumstances.

	10.11 	Rights of Rescission and Withdrawal for Holders 

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

 THIS IS TO CERTIFY
THAT, for value received, 
 (the “Warrantholder”) is the registered holder of the number of common share purchase warrants (the
“Warrants”) of Cohbar, Inc. (the “Corporation”) specified above, and is entitled, on exercise of these Warrants upon and subject to the terms and conditions set forth herein and in the Warrant Indenture, to
purchase for each Warrant, at any time before 5:00 p.m. (Toronto time) on [—], 2016 (the “Expiry Time”), subject to the Acceleration Right, one fully paid and
non-assessable share of the Corporation’s common stock, US$0.001 par value per share (a “Common Share”), subject to adjustment in accordance with the terms of the Warrant Indenture. 

For the purpose of this Warrant Certificate and the Warrant Indenture, “Acceleration Right” means the right of the Company to accelerate the
Expiry Time to a date that is not the less than 30 days following delivery of the Acceleration Notice if, at any time after the Common Shares are first traded on the TSXV, the volume weighted average trading price of the Common Shares on the TSXV,
or if the Common Shares are not then listed on the TSXV, on such other stock exchange on which the Common Shares are principally traded, equals or exceeds $3.00 for 20 consecutive Trading Days, provided that the Corporation provides the Acceleration
Notice to each registered holder of Warrants within five (5) Business Days. 
 The right to purchase Common Shares may only be exercised by the
Warrantholder within the time set forth above by: 
  

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

  

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


  
 A-2 








 Subject to adjustment thereof in the events and in the manner set forth in the Warrant Indenture hereinafter
referred to, the exercise price payable for each Common Share upon the exercise of Warrants shall be $2.00 per Common Share (the “Exercise Price”). 

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

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

This Warrant Certificate evidences Warrants of the Corporation issued or issuable under the provisions of a warrant indenture (which indenture together with
all other instruments supplemental or ancillary thereto is herein referred to as the “Warrant Indenture”) dated as of [—], 2014 between the Corporation and CST
Trust Company, as Warrant Agent, to which Warrant Indenture reference is hereby made for particulars of the rights of the holders of Warrants, the Corporation and the Warrant Agent in respect thereof and the terms and conditions on which the
Warrants are issued and held, all to the same effect as if the provisions of the Warrant Indenture were herein set forth, to all of which the holder, by acceptance hereof, assents. The Corporation will furnish to the holder, on request and without
charge, a copy of the Warrant Indenture. 
 On presentation at the principal office of the Warrant Agent as set out above, subject to the provisions of the
Warrant Indenture and on compliance with the reasonable requirements of the Warrant Agent, one or more Warrant Certificates may be exchanged for one or more Warrant Certificates entitling the holder thereof to purchase in the aggregate an equal
number of Common Shares as are purchasable under the Warrant Certificate(s) so exchanged. 
 If the issuance of Common Shares upon exercise hereof is not
registered under an effective Registration Statement under the United States Securities Act of 1933, as amended (the “U.S. Securities Act”), or U.S. state securities laws, then these Warrants may not be exercised in the United States or by
or on behalf of, or for the account or benefit of, a U.S. Person or a person in the United States absent an exemption from the registration requirements of the U.S. Securities Act and applicable state securities law. 

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 upon the occurrence of 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. 

  
 A-3 








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

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

This Warrant Certificate will not be valid for any purpose until it has been countersigned by or on behalf of the Warrant Agent from time to time under the
Warrant Indenture. 
 The parties hereto have declared that they have required that these presents and all other documents related hereto be in the English
language. Les parties aux présentes déclarent qu’elles ont exigé que la présente convention, de même que tous les documents s’y rapportant, soient rédigés en anglais. 

IN WITNESS WHEREOF the Corporation has caused this Warrant Certificate to be duly executed as of

 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. All securityholders or a legally authorized representative must sign this form. 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

	 	•	 	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 Guaranteed” 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.

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).
