United States or to Persons for the account or benefit of a U.S. Person or a Person in the United States, as well as all certificates
issued in exchange for or in substitution of such certificates representing Warrants are not to be issued in the form of a Global
Warrant Certificate and shall bear the following legend:



“THE
SECURITIES REPRESENTED HEREBY AND THE SECURITIES ISSUABLE UPON EXERCISE HEREOFHAVE NOT BEEN AND WILL NOT BE REGISTERED
UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “1933 ACT”), OR THE LAWS OF ANY STATE OF THE UNITED
STATES. THE HOLDER HEREOF, BY PURCHASING SUCH SECURITIES, AGREES FOR THE BENEFIT OF THE CORPORATION THAT SUCH SECURITIES MAY BE

RULE 904 OF REGULATION S UNDER THE 1933 ACT AND IN COMPLIANCE WITH APPLICABLE LOCAL LAWS AND REGULATIONS, (C) IN COMPLIANCE WITH

THE SELLER FURNISHES TO THE CORPORATION AN OPINION OF COUNSEL OF RECOGNIZED STANDING IN FORM AND SUBSTANCE REASONABLY SATISFACTORY
TO THE CORPORATION TO SUCH EFFECT. DELIVERY OF THIS CERTIFICATE MAY NOT CONSTITUTE “GOOD DELIVERY” IN SETTLEMENT OF
TRANSACTIONS ON STOCK EXCHANGES IN CANADA.”



provided, that if the Warrants are being
sold in compliance with the requirements of Rule 904 of Regulation S, and provided further that the Corporation is a "foreign
issuer" within the meaning of Regulation S at the time of sale, the above legend may be removed by providing a declaration
to the Warrant Agent to the following effect (or as the Corporation may prescribe from time to time):

such term is defined in Rule 144(a)(3) under the 1933 Act), (5) the seller does not intend to replace such securities with fungible
unrestricted securities and (6) the contemplated sale is not a transaction, or part of a series of transactions which, although
in technical compliance with Regulation S under the 1933 Act, is part of a plan or scheme to evade the registration provisions
of the 1933 Act. Unless otherwise defined herein, terms used herein have the meanings given to them by Regulation S under the 1933
Act.”;



notwithstanding the foregoing, the Corporation
may impose additional requirements for the removal of legends from securities sold in accordance with Rule 904 of Regulation S
in the future; and



provided, further, that if any such
securities are being sold pursuant to Rule 144 under the 1933 Act, the above legend may be removed by delivery to the Warrant Agent
of an opinion of counsel of recognized standing in form and substance reasonably satisfactory to the Corporation to the effect
that such legend is no longer required under applicable requirements of the 1933 Act or state securities laws.

any cash or other consideration such holder might otherwise be entitled to based upon the holding of such Warrant Certificate.

to be issued to such Warrantholder shall be rounded down to the next whole number and the Warrantholder shall not be entitled to
any compensation in respect of such fractional Warrant.

by entry on the register maintained by the Warrant Agent pursuant to Section 2.8 hereof of the particulars of such Warrant. Such
entry on the register maintained by the Warrant Agent pursuant to Section 2.8 hereof of the particulars of a Warrant issued in
uncertificated form shall be conclusive evidence that such Warrant is a valid and binding obligation of the Corporation and that
the holder is entitled to the benefits of this Indenture. The authentication of the Warrant Agent with respect to Warrants issued
in uncertificated form hereunder shall not be construed as a representation or warranty by the Warrant Agent as to the validity
of this Indenture or the Warrants (except the due authentication thereof) 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 except as otherwise specified herein.



2.3           Warrantholder
not a Shareholder:



Nothing in this Indenture nor in the holding
of a Warrant represented by a Warrant Certificate, or held in uncertificated form, shall be construed as conferring upon a Warrantholder
any right or interest whatsoever as a Shareholder including, but not limited to, the right to vote at, to receive notice of, or
to attend, meetings of Shareholders or any other proceedings of the Corporation or the right to receive dividends or other distributions.

of the Corporation and may, but need not be, under the seal of the Corporation or a reproduction thereof (which shall be deemed
to be the seal of the Corporation). The signatures of such officers or directors, as the case may be, may be mechanically reproduced

manually signed by such officers or directors. Notwithstanding that any of the persons whose manual or facsimile signature appears
on any Warrant Certificate as one of such officers or directors may no longer hold office at the date of such Warrant Certificate

Warrant Agent shall be valid and binding upon the Corporation and the holder thereof shall be entitled to the benefits of this
Indenture.

2.5           Countersignature
by the Warrant Agent:



(a)          Countersignature:
No Warrant Certificate shall be issued or, if issued, shall be valid for any purpose or entitle the holder to the benefits hereof
until it has been countersigned by the Warrant Agent by means of a manual signature of one or more of its authorized officers,
substantially in the form of the countersignature contained on the Warrant Certificate or in some other form approved by the Corporation
and the Warrant Agent and such countersignature by the Warrant Agent upon any Warrant Certificate shall be conclusive evidence
as against the Corporation that the Warrant Certificate so countersigned has been issued hereunder and that the holder thereof
is entitled to the benefits hereof.



(b)          No
Representation: The countersignature by the Warrant Agent on Warrant Certificates issued hereunder shall not be construed as
a representation or warranty by the Warrant Agent as to the validity of this Indenture or of the Warrant Certificate (except the
due countersignature 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 Warrant Certificates or any of them or of the consideration
therefor, except as otherwise specified herein.



2.6           Issue
in Substitution for Lost Warrant Certificate:



(a)          Substitution:
In case any Warrant Certificate issued and countersigned hereunder shall become mutilated, lost, destroyed or stolen, the Corporation,
subject to applicable law, shall issue and thereupon the Warrant Agent shall countersign and deliver a new certificate for the
same class of Warrants and of like date and tenor, and bearing the same legends, if any, as the one mutilated, lost, destroyed
or stolen (i) in exchange for and in place of and upon cancellation of such mutilated certificate, or (ii) in lieu of and in substitution
for such lost, destroyed or stolen certificate and the substituted certificate shall be in a form approved by the Warrant Agent

furnish to the Corporation and to the Warrant Agent such evidence of ownership and of the loss, destruction or theft, as the case
may be, of the certificate so lost, destroyed or stolen as shall be satisfactory to the Corporation and to the Warrant Agent in
their discretion, acting reasonably, and such applicant may also be required to furnish an indemnity and a surety bond in amount
and form satisfactory to the Corporation and the Warrant Agent in their discretion, acting reasonably, to save each of them harmless,
and shall pay the reasonable expenses, charges and any taxes applicable thereto of the Corporation and the Warrant Agent in connection
therewith.

2.7           Exchange
of Warrant Certificates:



(a)          Exchange:
Warrant Certificates issued and countersigned hereunder representing any specified number of Warrants to subscribe for and purchase
Common Shares may, upon compliance with the reasonable requirements of the Warrant Agent, be exchanged for Warrant Certificates
representing in the aggregate the same number of Warrants and entitling the holder thereof to subscribe for and purchase an equal
aggregate number of Common Shares at the same Exercise Price and on the same terms as the Warrant Certificates so exchanged.



(b)          Places
of Exchange: Warrant Certificates may be exchanged at the principal office of the Warrant Agent in the City of Toronto, Ontario,

register of holders in which shall be entered the names and addresses of the holders of Warrants and particulars of the Warrants
held by them; and



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

of the Warrant Certificate representing such Warrant (other than in the case of Warrants issued in uncertificated form), duly endorsed
by, or accompanied by a written instrument of transfer in form satisfactory to the Warrant Agent executed by the registered holder
or his executors, administrators or other legal representatives or his or their attorney duly appointed by an instrument in writing

as the Warrant Agent may prescribe, such transfer will be recorded on the appropriate register of transfers by the Warrant Agent.

representing such Warrant as required by Section 2.8(b) hereof and upon compliance with all other conditions in respect thereof
required by this Indenture or by law, be entitled to be entered on the appropriate register of holders referred to in Section 2.8(a)
hereof, or on any branch registers of holders maintained pursuant to Section 2.8(g) hereof, as the owner of such Warrant free from
all equities or rights of set-off or counterclaim between the Corporation and the transferor or any previous holder of such Warrant,

enter the name of any transferee, of any Warrant on the registers referred to in Section 2.8(a) hereof, or on any branch registers
maintained pursuant to Section 2.8(g) hereof, if such transfer would constitute a violation of the securities laws of any jurisdiction
or the rules, regulations or policies of any regulatory authority having jurisdiction.In particular, none of the Warrants
and none of the Common Shares issuable on the exchange of the Warrants has been or will be registered under the 1933 Act or any
state securities laws and such securities may not be offered or sold to a U.S. Person, a Person in the United States or a Person
for the account or benefit of a U.S. Person, or a Person in the United States absent an exemption from the registration provisions
of the 1933 Act and all applicable state securities laws.



(e)          No
Notice of Trusts: Subject to applicable law, neither the Corporation nor the Warrant Agent will be bound to take notice of
or see to the execution of any trust, whether express, implied or constructive, in respect of any Warrant, and may transfer any
Warrant on the direction of the person registered as the holder thereof, whether named as trustee or otherwise, as though that
person were the beneficial owner thereof.



(f)          Inspection:
The registers referred to in Section 2.8(a) hereof, and any branch registers maintained pursuant to Section 2.8(g) hereof, will
at all reasonable times be open for inspection by the Corporation and any Warrantholder. The Warrant Agent will from time to time
when requested to do so in writing by the Corporation or any Warrantholder (upon payment of the reasonable charges of the Warrant
Agent), furnish the Corporation or such Warrantholder with a list of the names and addresses of holders of Warrants (in the case
of a Warrantholder of the same class as such Warrantholder) entered on such registers and showing the number of Warrants (in the
case of a Warrantholder of the same class as such Warrantholder) held by each such holder thereof.



(g)          Location
of Registers: The Corporation may at any time and from time to time change the place at which the registers referred to in

registers or change the place at which such branch registers are kept, in each case subject to the approval of the Warrant Agent.
Notice of all such changes or closures shall be given by the Corporation to the Warrant Agent and to holders of Warrants in accordance
with Article 12 hereof.



(h)          Restrictions

form set forth in Section 2.1(c), the Warrant Agent shall only permit such transfer if it is (A) to the Corporation, (B) made outside
the United States in accordance with the requirements of Rule 904 of Regulation S and in compliance with applicable local laws
and regulations, (C) made in compliance with an exemption from registration under the 1933 Act provided by (i) Rule 144 thereunder,
if available, or (ii) Rule 144A thereunder, if available, and, in both cases, in accordance with applicable state securities laws
or (D) in another transaction that does not require registration under the 1933 Act or any applicable state securities laws and,
in the case of (C)(i) and (D) above, after the holder has furnished to the Corporation an opinion of counsel of recognized standing
in form and substance reasonably satisfactory to the Corporation to such effect.



- 13 -







(i)          Reliance
by Warrant Agent: The Warrant Agent shall have no obligation to ensure or verify compliance with any Applicable Legislation
or regulatory requirements on the issue, exercise or transfer of any Warrants or any Common Shares or other securities issued upon
the exercise of any Warrants. The Warrant Agent shall be entitled to process all proferred transfers and exercises of Warrants
upon the presumption that such transfers or exercises are permissible pursuant to all Applicable Legislation and regulatory requirements
and the terms of the Indenture and the related Warrant Certificates in the absence of prima facie evidence to the contrary.
The Warrant Agent may assume for the purposes of this Indenture that the address on the register of Warrantholders of any Warrantholder
is the actual address of such Warrantholder and is also determinative of the residency of such Warrantholder and that the address
of any transferee to whom any Warrants or Common Shares or other securities issuable upon the exercise of any Warrants are to be
registered, as shown on the transfer document, is the actual address of the transferee and is also determinative of the residency
of the transferee.



2.9           Ownership
of Warrants:



(a)          Owner:
The Corporation and the Warrant Agent may deem and treat the person in whose name any Warrant is registered as the absolute owner
of such Warrant for all purposes, and such person will for all purposes of this Indenture be and be deemed to be the absolute owner
thereof, and the Corporation and the Warrant Agent will not be affected by any notice or knowledge to the contrary except as required
by statute or by order of a court of competent jurisdiction.



(b)          Rights
of Registered Holder: The registered holder of any Warrant will be entitled to the rights evidenced thereby free from all equities
and rights of set-off or counterclaim between the Corporation and the original or any intermediate holder thereof and all persons
may act accordingly, and the issue and delivery to any such registered holder of the Common Shares issuable pursuant thereto will
be a good discharge to the Corporation and the Warrant Agent therefor and neither the Corporation nor the Warrant Agent will be
bound to inquire into the title of any such registered holder.



2.10         Transfer
of Warrants Represented by Global Warrant Certificates:



(a)          Transfer

Warrant Certificates, the Corporation shall, at its sole option, specify, in a Written Direction of the Corporation delivered to
the Warrant Agent, that some or all of the Warrants are to be represented by CDS Global Warrants registered in the name of CDS
or its nominee, and in the event the Warrants are to be represented by a Global Warrant Certificate, the Corporation shall execute
and the Warrant Agent shall certify and deliver one or more Global Warrant Certificates that shall:



- 14 -







(i)         represent
the aggregate number of outstanding Warrants to be represented by such  Global Warrant Certificate(s);



(ii)        be
delivered by the Warrant Agent to CDS or pursuant to CDS’ instructions; and



(iii)       if

(THE “ISSUER”) OR THE WARRANT 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 REGISTERED BY AN AUTHORIZED REPRESENTATIVE
OF CDS (AND ANY PAYMENT IS MADE TO CDS & CO., OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF CDS),
ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED HOLDER, CDS
& CO., HAS AN INTEREST HEREIN. THIS CERTIFICATE IS ISSUED PURSUANT TO A MASTER LETTER OF REPRESENTATION OF THE ISSUER TO CDS,
AS SUCH LETTER MAY BE REPLACED OR AMENDED FROM TIME TO TIME.”



(b)          Transfers
of Beneficial Ownership: Transfers of beneficial ownership in any Warrant represented by CDS Global Warrants will be effected
only (i) with respect to the interest of a Participant, through records maintained by CDS or its nominee for such CDS Global Warrants
, and (ii) with respect to the interest of any person other than a Participant, through records maintained by Participants. Beneficial
Owners who are not Participants but who desire to sell or otherwise transfer ownership of or any other interest in Warrants represented
by such CDS Global Warrants may do so only through a Participant.



(c)          Rights
of Beneficial Owners: The rights of Beneficial Owners shall be limited to those established by applicable law and agreements
between CDS and the Participants, and between such Participants and Beneficial Owners, and must be exercised through a Participant
in accordance with the rules and procedures of CDS;



(d)          No
Obligation to Deliver Certificates: Subject to subsection 2.11(e), neither the Corporation nor the Warrant Agent shall be under
any obligation to deliver to any Participant or Beneficial Owner, nor shall any Participant or Beneficial Owner have any right
to require the delivery of, a certificate or other instrument evidencing any interest in Warrants.



- 15 -







(e)          New
Certificates: If any Warrant is represented by CDS Global Warrants and any of the following events occurs:



| | (i) | CDS or the Corporation has notified the Warrant Agent that
(1) CDS is unwilling or unable to continue as depository or (2) CDS ceases to be a clearing agency in good standing under applicable
laws and, in either case, the Corporation is unable to locate a qualified successor depository within 90 days of delivery of such
notice;
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | the Corporation has determined, in its sole discretion,
to terminate the Book-Entry-Only system in respect of such CDS Global Warrant and has communicated such determination to the Warrant
Agent in writing;
| | ---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | the Corporation or CDS is required by applicable law to
take the action contemplated in this subsection 2.11(e); or
| | ----- | -------------------------------------------------------------------------------------------------------------------



| | (iv) | the Book-Entry-Only system administered by CDS ceases to
exist,
| | ---- | ---------------------------------------------------------------



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



Fully registered Warrant
Certificates issued and exchanged pursuant to this subsection 2.11(e) shall be registered in such names and in such denominations
as CDS shall instruct the Warrant Agent, provided that the aggregate number of Warrants represented by such Warrant Certificates
shall be equal to the aggregate number of Warrants represented by the CDS Global Warrants so exchanged. Upon exchange of a Global
Warrant Certificate for one or more Warrant Certificates in definitive form, such Global Warrant Certificate shall be cancelled
by the Warrant Agent.



(f)          No
Liability: Notwithstanding anything herein or in the terms of the Warrant Certificates to the contrary, neither the Corporation
nor the Warrant Agent nor any agent thereof shall have any responsibility or liability for (i) the records maintained by CDS relating
to any ownership interests or any other interests in the Warrants or the depository system maintained by CDS, or payments made
on account of any ownership interest or any other interest of any Person in any Warrant represented by any CDS Global Warrants
(other than CDS or its nominee). (ii) for maintaining, supervising or reviewing any records of CDS or any Participant relating
to any such interest, or (iii) any advice or representation made or given by CDS or those contained herein that relate to the rules
and regulations of CDS or any action to be taken by CDS on its own direction or at the direction of any Participant.



- 16 -







2.12         Issue
of Uncertificated Warrants to CDS:



(a)          Uncertificated
Warrants: With the exception of any Warrants issued to U.S. Persons, persons in the United States or persons acting for the
account or benefit of persons in the United States or U.S. Persons which shall be issued using individual physical Warrant Certificates,
the Corporation may, in its sole option, specify, in a written direction of the Corporation delivered to the Warrant Agent, that
some or all of the Warrants are to be issued in uncertificated form to CDS or its nominee.



(b)          Exercise
of Warrants: A Beneficial Owner of Warrants issued in uncertificated form who desires to exercise his or her Warrants must
do so by causing a Participant to deliver to CDS on behalf of the entitlement holder, notice of the owner’s intention to
exercise Warrants in a manner acceptable to CDS. Forthwith upon receipt by CDS of such notice, as well as payment for the Exercise
Price, CDS shall deliver to the Warrant Agent confirmation of its intention to exercise Warrants (a “Confirmation”)
in a manner acceptable to the Warrant Agent, including by electronic means through the book based registration system. Upon exercise
of the Warrants, such Participant will be deemed to be confirming that it (a) is not in the United States; (b) is not a U.S. Person
and is not exercising such Warrants on behalf of a U.S. Person or Person in the United States; and (c) did not execute or deliver
the notice of the owner’s intention to exercise such Warrants in the United States.



Payment representing the
Exercise Price must be provided to the appropriate office of the Participant in a manner acceptable to it. A notice in form acceptable
to the Participant (together with a written confirmation substantially the same as the Confirmation) and payment from such Beneficial
Owner should be provided to the Participant sufficiently in advance so as to permit the Participant to deliver notice and payment
to CDS and for CDS in turn to deliver notice and payment to the Warrant Agent prior to the Time of Expiry. CDS will initiate the
exercise by way of the Confirmation and forward the Exercise Price electronically to the Warrant Agent and the Warrant Agent will
execute the exercise by issuing to CDS through the book based registration system the Common Shares to which the exercising Beneficial
Owner is entitled pursuant to the exercise. Any expense associated with the exercise process will be for the account of the Corporation.



Article
3 - WARRANTS TO RANK PARI PASSU



3.1           Warrants
to Rank Pari Passu:



All Warrants shall rank pari passu,
whatever may be the actual date of issue of the Warrant Certificates that evidence them, or the actual date of authentication of
the Warrants issued in uncertificated form.



- 17 -







Article
4 - EXERCISE OF WARRANTS



4.1           Method
of Exercise of Warrants:



(a)          Exercise:
Subject to Sections 4.1(b) and 4.1(c) hereof, the holder of any Warrant may exercise the right thereby conferred on such holder
to subscribe for and purchase Common Shares by surrendering, after the date of issue of the Warrant but prior to the Time of Expiry,
to the Warrant Agent at the place specified in Section 4.1(e) hereof or any other place or places that may be designated by the
Corporation with the approval of the Warrant Agent:



| | (i) | the Warrant Certificate, with a properly completed and
executed subscription form in substantially the form contained on the Warrant Certificate; and
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | a certified cheque, bank draft or money order in lawful
money of Canada payable to or to the order of the Corporation at par in the city where such Warrant Certificate is surrendered
for exercise, in an amount equal to the product obtained by multiplying the Exercise Price by the number of Common Shares subscribed
for pursuant to such Warrant Certificate.
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



A Warrant Certificate with the duly completed
and executed subscription form referred to in Section 4.1(a)(i) above, together with the certified cheque, bank draft or money
order referred to in Section 4.1(a)(ii) above, shall be deemed to be surrendered only upon delivery thereof or, if sent by mail
or other means of transmission, upon receipt thereof, in each case at the office of the Warrant Agent provided for in Section 4.1(e)
hereof or any such other place designated by the Corporation with the approval of the Warrant Agent.



A Beneficial Owner who desires to exercise
his or her Warrants, must do so by causing a Participant to deliver to CDS (at its office in Toronto), on behalf of the Beneficial
Owner, a written notice of the Beneficial Owner’s intention to exercise Warrants (the “Exercise Notice”).
Any expenses associated with the preparation and delivery of Exercise Notices will be for the account of the Beneficial Owner exercising
the Warrants.



(b)          Restrictions
on Exercise under United States Securities Laws: The Warrants may not be exercised by or on behalf of a person in the United
States or a U.S. Person unless registered under the 1933 Act or unless an exemption is available from the registration requirements
of the 1933 Act and applicable state securities laws and the holder of the Warrants has furnished an opinion of counsel of recognized
standing or other evidence in form and substance reasonably satisfactory to the Corporation to such effect; provided, however,
that a Warrantholder who is an "accredited investor," as such term is defined in Rule 501(a) of Regulation D under the
1933 Act (a "U.S. Accredited Investor"), at the time of exercise of Warrants and that purchased units ("Units"),
with each Unit comprised of one common share and one Warrant, in the Corporation’s private placement of Units in the United
States and to U.S. Persons will not be required to deliver an opinion of counsel or other evidence in connection with the exercise
of Warrants underlying those Units as long as the Warrantholder is a U.S. Accredited Investor and the other representations and
warranties made by such Warrantholder at the time of purchase of the Units also remain true and correct.



- 18 -







(c)          Limitations
on Exercises – Maximum Ownership Percentage: Notwithstanding anything to the contrary contained in this Indenture, Warrants
shall not be exercisable by U.S. Persons, persons in the United States and persons acting for the account or benefit of persons
in the United States or U.S. Persons (“U.S. Warrantholders”) to the extent (but only to the extent) that after
giving effect to such exercise the U.S. Warrantholder (together with any of its affiliates) would beneficially own in excess of
9.99% (the "Maximum Percentage") of the issued and outstanding Common Shares. For purposes of the foregoing sentence,
the aggregate number of Common Shares beneficially owned by the U.S. Warrantholder and its affiliates shall include the number
of Common Shares issuable upon exercise of Warrants with respect to which the determination of such sentence is being made, but
shall exclude Common Shares which would be issuable upon (x) exercise of the remaining, unexercised portion of Warrants beneficially
owned by the Holder and its affiliates, and (y) exercise or conversion of the unexercised or unconverted portion of any other securities
of the Corporation beneficially owned by the U.S. Warrantholder and its affiliates (including, without limitation, any convertible
notes or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation
contained herein. To the extent the above limitation applies, the determination of whether any Warrants shall be exercisable (vis-à-vis
other convertible, exercisable or exchangeable securities owned by the U.S. Warrantholder or any of its affiliates) and of which
such securities shall be convertible, exercisable or exchangeable (as the case may be, as among all such securities owned by the
U.S. Warrantholder) shall, subject to such Maximum Percentage limitation, be determined on the basis of the first submission to
the Corporation for conversion, exercise or exchange (as the case may be). No prior inability to exercise Warrants pursuant to
this Indenture shall have any effect on the applicability of the provisions of this Section with respect to any subsequent determination
of exercisability.



For the purposes of this
Section, beneficial ownership and all determinations and calculations shall be determined in accordance with Section 13(d) of the
Securities Exchange Act of 1934 and the rules and regulations promulgated thereunder. The provisions of this Section may be implemented
in a manner otherwise than in strict conformity with the terms of this Section to correct this Section (or any portion hereof)
which may be defective or inconsistent with the intended Maximum Percentage beneficial ownership limitation herein contained or
to make changes or supplements necessary or desirable to properly give effect to such Maximum Percentage limitation. The limitations
contained in this Section shall apply to a successor to the U.S. Warrantholder.



The Corporation shall within
two (2) Business Day of a request from a U.S. Warrantholder, confirm orally and in writing to the U.S. Warrantholder the number
of Common Shares then outstanding, including by virtue of any prior conversion or exercise of convertible or exercisable securities
into Common Shares, including, without limitation, pursuant to this Indenture (a “Confirmation of Issued Shares”).



As a result of these limitations,
all Warrants (along with the duly completed subscription form) surrendered by U.S. Warrantholders to the Warrant Agent for exercise
will be forwarded onto the Corporation for their approval. Such approval will be provided to the Warrant Agent in the form of a
Certificate of the Corporation confirming that such U.S. Warrantholder will not beneficially own in excess of the Maximum Percentage
of the issued and outstanding Common Shares as a result of such exercise and therefore instructing the Warrant Agent to proceed
with the exercise requested and the Warrant Agent shall be fully protected in relying on such certificate.



- 19 -







The Warrant Agent will
not process any exercise of Warrants from U.S. Warrantholders unless it has received the above certificate from the Corporation.
For greater certainty, the Warrant Agent will have no responsibility for monitoring the beneficial ownership level of the Common
Shares held by U.S. Warrantholders and will have no liability in regards to the determinations made of whether or not a U.S. Warrantholder
would become a beneficial holder in excess of the Maximum Percentage of the issued and outstanding Common Shares, such determinations
will be the sole responsibility of the Corporation.



If
the Corporation has provided written notice (the “Expiry Notice”) to the Warrantholders that the closing price
of the Common Shares on the principal stock exchange of the Corporation has been three (3) times the Offering Price for twenty
(20) consecutive Trading Days, then in the event that the exercise of all Warrants held by a U.S. Warrantholder would result in
such U.S. Warrantholder (and its affiliates) beneficially owning a number of Common Shares in excess of the Maximum Percentage:



| | (i) | such U.S. Warrantholder shall be required, within 30 days
following receipt of the Expiry Notice, to exercise such number of Warrants such that the U.S. Warrantholder (and its affiliates)
will, following such exercise, beneficially own a number of Common Shares equal to the Maximum Percentage; and
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | if the U.S. Warrantholder has complied with paragraph (i)
above, the unexercised Warrants of each such U.S. Warrantholder will not be cancelled 30 days following delivery by the Corporation
of the Expiry Notice. If the U.S. Warrantholder does not comply with paragraph (i) above, their remaining Warrants will become
null and void on the accelerated Expiry Date.
| | ---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



In the instance of an Expiry
Notice being delivered to Warrantholders, then prior to the Time of Expiry, the Corporation will provide the Warrant Agent with
a Certificate of the Corporation confirming the registration particulars and the number of remaining Warrants held by each U.S.
Warrantholder who has complied with Section 4.1(c)(i) and that as a result their Warrants will remain outstanding.



Notwithstanding
any other provision hereof:



| | (iii) | the provisions of this Section 4.1(c) shall not apply to
a U.S. Warrantholder who, together with any of its affiliates, beneficially owns in excess of the Maximum Percentageof
the issued and outstanding Common Shares on the date immediately prior to the Closing Date; and
| | ----- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | in no event shall the Expiry Date of any unexercised Warrants
be extended beyond (60) months from the Closing Date.
| | ---- | -------------------------------------------------------------------------------------------------------------------



- 20 -







(d)          Subscription
Form Completion: Any subscription form referred to in Section 4.1(a) hereof shall be signed by the Warrantholder, or his executors,
administrators or other legal representatives or his or their attorney duly appointed by an instrument in writing in form and executed
in a manner satisfactory to the Warrant Agent, acting reasonably, and shall specify (A) the number of Common Shares which the holder
desires to subscribe for and purchase, such number being not more than the number which the holder is entitled to subscribe for
and purchase pursuant to the Warrant Certificate surrendered, (B) the person or persons in whose name or names such Common Shares
are to be issued, (C) the address or addresses of such person or persons, or the office of the Warrant Agent at which the Warrant
Certificate was surrendered and the certificates representing such Common Shares are to be sent, and (D) the number of Common Shares
to be issued to each such person if more than one is so specified. If any of the Common Shares subscribed for are to be issued
to a person or persons other than the Warrantholder, the Warrantholder shall pay to the Warrant Agent all applicable transfer or
similar taxes, if any, and, the Corporation and the Warrant Agent shall not be required to issue or deliver certificates representing
Common Shares unless or until such Warrantholder shall have paid to the Warrant Agent the amount of such tax, if any, or shall
have established to the satisfaction of the Warrant Agent that such tax has been paid or that no tax is due.



(e)          Places
for Exercise: The Corporation has designated the Warrant Agent, at its principal office in the City of Toronto, Ontario, as
the place at which the Warrants may be exercised. The Corporation will give notice to the Warrantholders pursuant to Article 12
hereof of the location of any other place appointed by the Corporation and approved by the Warrant Agent and of the change in the
location of any new or existing place where Warrants may be exercised.



(f)          Accounting
to Corporation: The Warrant Agent shall as soon as practicable account to the Transfer Agent and the Corporation with respect
to Warrants exercised. All such monies, and any securities or other instruments, from time to time received by the Warrant Agent
shall be received as agent for, and shall be segregated and kept apart by the Warrant Agent as agent for, the Corporation. Within
five Business Days of receipt thereof the Warrant Agent shall forward to the Corporation (or to an account or accounts of the Corporation
with a bank or trust company designated in writing by the Corporation for that purpose) all monies received through the exercise
of Warrants pursuant to this Article 4.



(g)          Record
of Exercise: The Warrant Agent shall record the particulars of the Warrants exercised for Common Shares which particulars shall
include the names and addresses of the persons who become holders of Common Shares, if any, on exercise, the number of Common Shares
issued, the Exercise Date and the Exercise Price. Within five Business Days of each Exercise Date, the Warrant Agent shall provide
such particulars in writing to the Corporation.



(h)          United
States Legend on Common Share Certificate; Restrictions on Transfer under United States Securities Laws



(i)          Any
certificates representing Common Shares issued to, or for the account or benefit of, a person who cannot make the representations
set forth in Box A on the subscription form of the Warrant Certificate, and any certificates issued in exchange therefor or in
substitution thereof, shall bear the following legend until such time as it is no longer required under the 1933 Act and applicable
state securities laws:



- 21 -







“THE
SECURITIES REPRESENTED HEREBYHAVE NOT BEEN AND WILL NOT BE REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS
AMENDED (THE “1933 ACT”), OR THE LAWS OF ANY STATE OF THE UNITED STATES. THE HOLDER HEREOF, BY PURCHASING SUCH SECURITIES,
AGREES FOR THE BENEFIT OF THE CORPORATION THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY (A)
TO THE CORPORATION, (B) OUTSIDE THE UNITED STATES IN ACCORDANCE WITH RULE 904 OF REGULATION S UNDER THE 1933 ACT AND IN COMPLIANCE
WITH APPLICABLE LOCAL LAWS AND REGULATIONS, (C) IN COMPLIANCE WITH THE EXEMPTION FROM REGISTRATION UNDER THE 1933 ACT PROVIDED
BY (1) RULE 144 THEREUNDER, IF AVAILABLE, OR (2) RULE 144A THEREUNDER, IF AVAILABLE, AND, IN BOTH CASES, IN ACCORDANCE WITH APPLICABLE
STATE SECURITIES LAWS OR (D) IN ANOTHER TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE 1933 ACT OR ANY APPLICABLE STATE
SECURITIES LAWS AND, IN THE CASE OF (C)(1) AND (D) ABOVE, AFTER THE SELLER FURNISHES TO THE CORPORATION AN OPINION OF COUNSEL OF
RECOGNIZED STANDING IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE CORPORATION TO SUCH EFFECT. DELIVERY OF THIS CERTIFICATE
MAY NOT CONSTITUTE “GOOD DELIVERY” IN SETTLEMENT OF TRANSACTIONS ON STOCK EXCHANGES IN CANADA.”



provided, that if any such
securities are being sold in compliance with the requirements of Rule 904 of Regulation S, and provided further that the Corporation
is a "foreign issuer" within the meaning of Regulation S at the time of sale, the above legend may be removed by providing
a declaration to the Warrant Agent to the following effect (or as the Corporation may prescribe from time to time):



- 22 -







“The undersigned (a) acknowledges
that the sale of Common Shares of Cynapsus Therapeutics Inc. (the “Corporation”) to which this declaration relates,
represented by certificate number ________, is being made in reliance on Rule 904 of Regulation S under the United States Securities
Act of 1933, as amended (the “1933 Act”), and (b) certifies that (1) the undersigned is not an “affiliate”
(as that term is defined in Rule 405 under the 1933 Act) of the Corporation, (2) the offer of such securities was not made to a
person in the United States and either (A) at the time the buy order was originated, the buyer was outside the United States, or
the seller and any person acting on its behalf reasonably believed that the buyer was outside the United States, or (B) the transaction
was executed in, on or through the facilities of a designated offshore securities market and neither the seller nor any person
acting on its behalf knows that the transaction has been prearranged with a buyer in the United States, (3) neither the seller
nor any affiliate of the seller nor any person acting on any of their behalf has engaged or will engage in any directed selling
efforts in the United States in connection with the offer and sale of such securities, (4) the sale is bona fide and not for the
purpose of “washing off” the resale restrictions imposed because the securities are “restricted securities”
(as such term is defined in Rule 144(a)(3) under the 1933 Act), (5) the seller does not intend to replace such securities with
fungible unrestricted securities and (6) the contemplated sale is not a transaction, or part of a series of transactions which,
although in technical compliance with Regulation S under the 1933 Act, is part of a plan or scheme to evade the registration provisions
of the 1933 Act. Unless otherwise defined herein, terms used herein have the meanings given to them by Regulation S under the 1933
Act.”;



notwithstanding the foregoing,
the Corporation may impose additional requirements for the removal of legends from securities sold in accordance with Rule 904
of Regulation S in the future; and



provided further, that, if
any of such securities are being sold pursuant to Rule 144 of the 1933 Act, the legend may be removed by delivery to the Corporation
and the Warrant Agent of an opinion of counsel of recognized standing in form and substance reasonably satisfactory to the Corporation
to the effect that the legend is no longer required under applicable requirements of the 1933 Act or state securities laws.



(ii)         If
a certificate representing Common Shares is tendered for transfer and bears a legend in the form set forth in this Section 4.1(h),
the Transfer Agent shall only permit such transfer if it is (A) to the Corporation, (B) made outside the United States in accordance
with the requirements of Rule 904 of Regulation S and in compliance with applicable local laws and regulations, (C) made in compliance
with an exemption from registration under the 1933 Act provided by (i) Rule 144 thereunder, if available, or (ii) Rule 144A thereunder,
if available, and, in both cases, in accordance with applicable state securities laws or (D) in another transaction that does not
require registration under the 1933 Act or any applicable state securities laws and, in the case of (C)(i) and (D) above, after
it has furnished to the Corporation an opinion of counsel of recognized standing in form and substance reasonably satisfactory
to the Corporation to such effect.



4.2           Effect
of Exercise of Warrants:



(a)          Effect
of Exercise: Upon compliance by the holder of any Warrant Certificate with the provisions of Section 4.1 hereof, but subject
to the provisions of Section 4.3(b) hereof, the number of Common Shares subscribed for and purchased 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 record of such Common Shares on the Exercise Date thereof unless the transfer books of the Corporation shall be closed on such
date, in which case the Common Shares subscribed for and purchased shall be deemed to have been issued, and such person or persons
shall be deemed to have become the holder or holders of record of such Common Shares on the date on which such transfer books are
reopened but such Common Shares shall be issued at the Exercise Price in effect on the Exercise Date.



- 23 -







(b)          Issue
of Share Certificates: As soon as practicable, and in any event no later than the third Business Day on which the transfer
books of the Corporation have been opened after the exercise of a Warrant as aforesaid, the Corporation shall forthwith (i) cause
to be mailed to the person or persons in whose name or names the Common Shares so subscribed for and purchased are to be issued,
as specified in the subscription completed on the Warrant Certificate, at the address specified in such subscription form, or (ii)
if specified in such subscription form, cause to be delivered to such person or persons at the office of the Warrant Agent where
such Warrant Certificate was surrendered, a certificate or certificates representing the appropriate number of Common Shares to
which the Warrantholder is entitled and elected to subscribe for and purchase pursuant to the Warrant Certificate surrendered to
the Warrant Agent.



4.3           Subscription
for Less than Entitlement:



(a)          Exercise
for Less Than Maximum: The holder of any Warrant Certificate may subscribe for and purchase a number of Common Shares less
than the maximum number which the holder is entitled to subscribe for and purchase pursuant to the surrendered Warrant Certificate,
provided that in no event shall fractional Common Shares be issued in connection with the exercise of Warrants. In such event,
the holder thereof upon exercise thereof shall, in addition, be entitled to receive a new Warrant Certificate complying with Section
2.2 hereof in respect of the balance of the Warrants not then exercised.



(b)          No
Fractional Common Shares: Notwithstanding any adjustment provided for in Article 5 hereof or otherwise, the Corporation shall
not be required upon the exercise of a Warrant to issue fractions of Common Shares or to distribute certificates which evidence
fractional Common Shares. If the number of Common Shares to which a Warrantholder would otherwise be entitled upon the exercise
of a Warrant is not a whole number then, subject to Section 4.4 hereof, the number of Common Shares to be issued shall be rounded
down to the next whole number and the holder of such Warrant Certificate shall not be entitled to any compensation in respect of
any fractional Common Share.



4.4           Warrant
Certificates for Fractions of Common Shares:



To the extent that the holder of a Warrant
Certificate is entitled to receive on the exercise or partial exercise thereof a fraction of a Common Share, such right may only
be exercised in respect of such fraction in combination with another Warrant Certificate which in the aggregate entitles the Warrantholder
to receive a whole number of Common Shares.



4.5           Surrender
of Warrant Certificates:



All Warrant Certificates surrendered to the
Warrant Agent pursuant to Sections 2.6, 2.7, 2.8 and 4.1(a) shall be cancelled by the Warrant Agent. The Warrant Agent shall, if
required by the Corporation, furnish the Corporation with a certificate identifying the Warrant Certificates so cancelled. All
Warrants represented by Warrant Certificates which have been duly cancelled shall be without further force or effect whatsoever.



4.6           Expiration
of Warrants:



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

Article
5 - ADJUSTMENTS



5.1           Adjustment
of Exercise Price and Number of Common Shares Purchasable Upon Exercise:



The Exercise Price and the number of Common
Shares purchasable upon the exercise of the Warrants shall be subject to adjustment from time to time in the events and in the
manner provided in the following subsections:



(a)          Stock
Dividend; Distribution of Common Shares; Subdivision; Consolidation: If at any time after the Effective Date but prior to the
Expiry Date, the Corporation shall:



| | (i) | fix a record date for the issue of, or issue, Common Shares
or securities exchangeable for or convertible into Common Shares to the holders of all or substantially all of the outstanding
Common Shares by way of a stock dividend or otherwise, other than as a Dividend Paid In The Ordinary Course,
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | fix a record date for the distribution to, or make a distribution
to, the holders of all or substantially all of the outstanding Common Shares payable in Common Shares or securities exchangeable
for or convertible into Common Shares, other than as a Dividend Paid In The Ordinary Course,
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | subdivide, redivide or change the outstanding Common Shares
into a greater number of Common Shares, or
| | ----- | ------------------------------------------------------------------------------------------------------



| | (iv) | consolidate, reduce or combine the outstanding Common Shares
into a lesser number of Common Shares,
| | ---- | ---------------------------------------------------------------------------------------------------



(any of such events in Sections 5.1(a)(i),
(ii), (iii) and (iv) above being herein called a "Common Share Reorganization"), the Exercise Price shall be adjusted
on the earlier of the record date on which holders of Common Shares are determined for the purposes of the Common Share Reorganization
and the effective date of the Common Share Reorganization to the amount determined by multiplying the Exercise Price in effect
immediately prior to such record date or effective date, as the case may be, by a fraction:



| | (A) | the numerator of which shall be the number of Common Shares
outstanding on such record date or effective date, as the case may be, before giving effect to such Common Share Reorganization;
and
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (B) | the denominator of which shall be the number of Common
Shares which will be outstanding immediately after giving effect to such Common Share Reorganization (including in the case of
a distribution of securities exchangeable for or convertible into Common Shares the number of Common Shares that would have been
outstanding had such securities been exchanged for or converted into Common Shares on such date).
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- 25 -







To the extent that any adjustment in the Exercise
Price occurs pursuant to this Section 5.1(a) as a result of the fixing by the Corporation of a record date for the distribution
of securities exchangeable for or convertible into Common Shares, the Exercise Price shall be readjusted immediately after the
expiry of any relevant exchange or conversion right to the Exercise Price which would then be in effect based upon the number of
Common Shares actually issued and remaining issuable after such expiry and shall be further readjusted in such manner upon the
expiry of any further such right. Any Warrantholder who has not exercised his right to subscribe for and purchase Common Shares
on or prior to the record date of such stock dividend or distribution or the effective date of such subdivision or consolidation,
as the case may be, upon the exercise of such right thereafter shall be entitled to receive and shall accept in lieu of the number
of Common Shares then subscribed for and purchased by such Warrantholder, at the Exercise Price determined in accordance with this
Section 5.1(a) the aggregate number of Common Shares that such Warrantholder would have been entitled to receive as a result of
such Common Share Reorganization, if, on such record date or effective date, as the case may be, such Warrantholder had been the
holder of record of the number of Common Shares so subscribed for and purchased.



(b)          Issue
of Rights, Options or Warrants: If at any time after the Effective Date but prior to the Expiry Date, the Corporation shall
fix a record date for the issue or distribution to the holders of all or substantially all of the outstanding Common Shares of
rights, options or warrants pursuant to which such holders are entitled, during a period expiring not more than 45 days after the
record date for such issue (such period being the "Rights Period"), to subscribe for or purchase Common Shares or securities
exchangeable for or convertible into Common Shares at a price per share to the holder (or in the case of securities exchangeable
for or convertible into Common Shares, at an exchange or conversion price per share) at the date of issue of such securities of
less than 95% of the Current Market Price of the Common Shares on such record date (any of such events being called a "Rights
Offering"), the Exercise Price shall be adjusted effective immediately after the record date for such Rights Offering to the
amount determined by multiplying the Exercise Price in effect on such record date by a fraction:



| | (i) | the numerator of which shall be the aggregate of
| | --- | ------------------------------------------------



| | (A) | the number of Common Shares outstanding on the record date
for the Rights Offering, and
| | --- | ---------------------------------------------------------------------------------------



| | (B) | the quotient determined by dividing
| | --- | -----------------------------------



| | I. | either (a) the product of the number of Common Shares offered
during the Rights Period pursuant to the Rights Offering and the price at which such Common Shares are offered, or, (b) the product
of the exchange or conversion price of the securities so offered and the number of Common Shares for or into which the securities
offered pursuant to the Rights Offering may be exchanged or converted, as the case may be, by
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- 26 -









| | II. | the Current Market Price of the Common Shares as of the record date for the Rights Offering; and
| | --- | ------------------------------------------------------------------------------------------------



| | (ii) | the denominator of which shall be the aggregate of the number of Common Shares outstanding on such
record date and the number of Common Shares offered pursuant to the Rights Offering (including in the case of the issue or distribution
of securities exchangeable for or convertible into Common Shares the number of Common Shares for or into which such securities
may be exchanged or converted).
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



(c)          Special Distributions:
If at any time after the Effective Date but prior to the Expiry Date, the Corporation shall fix a record date for the payment,
issue or distribution to the holders of all or substantially all of the outstanding Common Shares of:



| | (i) | shares of the Corporation or any other corporation of any class other than Common Shares;
| | --- | -----------------------------------------------------------------------------------------



| | (ii) | rights, options or warrants to acquire Common Shares or securities exchangeable for or convertible
into Common Shares (other than rights, options or warrants pursuant to which holders of Common Shares are entitled, during a period
expiring not more than forty-five (45) days after the record date for such issue, to subscribe for or purchase Common Shares or
securities exchangeable for or convertible into Common Shares at a price per share (or in the case of securities exchangeable for
or convertible into Common Shares at an exchange or conversion price per share) at the date of issue of such securities to the
holder of at least 95% of the Current Market Price of the Common Shares on such record date);
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | evidences of indebtedness of the Corporation; or
| | ----- | ------------------------------------------------



| | (iv) | any property or assets of the Corporation;
| | ---- | ------------------------------------------



and if such issue or distribution does
not constitute a Dividend Paid In The Ordinary Course,a Common Share Reorganization or a Rights Offering (any of such non-excluded
events being herein called a "Special Distribution"), the Exercise Price shall be adjusted effective immediately after
the record date for the Special Distribution to the amount determined by multiplying the Exercise Price in effect on the record
date for the Special Distribution by a fraction:



- 27 -







| | (A) | the numerator of which shall be the difference between:
| | --- | -------------------------------------------------------



| | I. | the product of the number of Common Shares outstanding on such record date and the Current Market
Price of the Common Shares on such record date, and
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------



| | II. | the fair market value, as determined in good faith by the Directors (whose determination shall
be conclusive, subject to the prior written consent, if required, of any stock exchange on which the Common Shares are then listed),
of such dividend, cash, securities, rights, options, warrants, evidences of indebtedness or property or assets to be issued or
distributed in the Special Distribution, and
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (B) | the denominator of which shall be the product obtained by multiplying the number of Common Shares
outstanding on such record date by the Current Market Price of the Common Shares on such record date.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Any Common Shares owned by or held for
the account of the Corporation shall be deemed not to be outstanding for the purpose of such calculation. To the extent that any
adjustment in the Exercise Price occurs pursuant to this Section 5.1(c) as a result of the fixing by the Corporation of a record
date for the issue or distribution of rights, options or warrants to acquire Common Shares or securities exchangeable for or convertible
into Common Shares referred to in this Section 5.1(c), the Exercise Price shall be readjusted immediately after the expiry of any
relevant exercise, exchange or conversion right to the amount which would then be in effect based upon the number of Common Shares
issued and remaining issuable after such expiry and shall be further readjusted in such manner upon the expiry of any further such
right.



(d)          Reclassification
of Common Shares; Consolidation; Amalgamation; Merger: If at any time after the Effective Date but prior to the Expiry Date
there shall occur:



| | (i) | a reclassification or redesignation of the Common Shares, a change of the Common Shares into other
shares or securities or any other capital reorganization involving the Common Shares other than a Common Share Reorganization;
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | a consolidation, arrangement, amalgamation or merger of the Corporation with or into another body
corporate which results in a reclassification or redesignation of the Common Shares or a change of the Common Shares into other
shares or securities;
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | the transfer, sale or conveyance of the undertaking or assets of the Corporation as an entirety
or substantially as an entirety to another corporation or entity;
| | ----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



- 28 -







(any of such events being called a "Capital
Reorganization"), after the effective date of the Capital Reorganization the Warrantholder shall be entitled to receive, and
shall accept, for the same aggregate consideration, upon exercise of the Warrants, in lieu of the number of Common Shares to which
the Warrantholder was theretofor entitled upon the exercise of the Warrants, the kind and aggregate number of shares and other
securities or property resulting from the Capital Reorganization which the Warrantholder would have been entitled to receive as
a result of the Capital Reorganization if, on the effective date thereof, the Warrantholder had been the registered holder of the
number of Common Shares which the Warrantholder was theretofor entitled to purchase or receive upon the exercise of the Warrants.
If necessary, as a result of any such Capital Reorganization, appropriate adjustments shall be made in the application of the provisions
of this Warrant Indenture with respect to the rights and interests thereafter of the Warrantholder to the end that the provisions
shall thereafter correspondingly be made applicable as nearly as may reasonably be possible in relation to any shares or other
securities or property thereafter deliverable upon the exercise of the Warrants. Any such adjustments shall be made by and set
forth in an indenture supplemental hereto with its successor or such corporation or other entity, as applicable, contemporaneously
with such reclassification, consolidation, amalgamation, arrangement, merger or other event and which supplemental indenture shall
be approved by action by the directors and shall for all purposes be conclusively deemed to be an appropriate adjustment. To give
effect to the provisions of this subsection, the Corporation shall or shall impose upon its successor or such purchasing corporation
or entity, as the case may be, prior to or contemporaneously with the Capital Reorganization, an agreement or an undertaking which
shall provide, to the extent possible, for the applications of the provisions set forth herein with respect to the rights and interests
thereafter of the Warrantholder to the extent that the adjustment provisions set forth in this Warrant Indenture shall thereafter
correspondingly be made applicable, as nearly as may reasonably be, with respect to any shares, other securities or property to
which the Warrantholder is entitled on exercise of acquisition rights hereunder. Any such agreement or undertaking shall provide
that such adjustments shall apply to successive Capital Reorganizations.



(e)           If at any time
after the Effective Date but prior to the Expiry Date any adjustment or readjustment in the Exercise Price shall occur pursuant
to the provisions of Sections 5.1(a), 5.1(b) or 5.1(c) of this Indenture, then the number of Common Shares purchasable upon the
subsequent exercise of Warrants shall be simultaneously adjusted or readjusted, as the case may be, by multiplying the number of
Common Shares purchasable upon the exercise of Warrants immediately prior to such adjustment or readjustment by a fraction which
shall be the reciprocal of the fraction used in the adjustment or readjustment of the Exercise Price.



| | 5.2 | Rules Regarding Calculation of Adjustment of Exercise Price and Number of Common Shares Purchasable
Upon Exercise:
| | --- | ------------------------------------------------------------------------------------------------------------------



For the purposes of Section 5.1 hereof
the following subsections shall apply:



(a)          Successive
Adjustments: Any adjustment made pursuant to Section 5.1 hereof shall be cumulative and made successively whenever an event
referred to therein shall occur, subject to the following provisions of this Section 5.2.



(b)          Minimum Adjustments:
No adjustment in the Exercise Price shall be required unless such adjustment would result in a change of at least 1% in the Exercise
Price and no adjustment shall be made in the number of Common Shares purchasable upon exercise of a Warrant unless it would result
in a change of at least one one-hundredth of a Common Share; provided, however, that any adjustments which, except for the provisions
of this Section 5.2(b), would otherwise have been required to be made, shall be carried forward and taken into account in any subsequent
adjustment, and provided further that in no event shall the Corporation be obligated to issue fractional Common Shares upon exercise
of Warrants.



- 29 -







(c)Mutatis
MutandisAdjustment: Subject to the prior written consent, if required, of any stock exchange upon which the Common
Shares or Warrants may be listed, no adjustment in the Exercise Price or in the number or kind of securities purchasable upon exercise
of a Warrant shall be made in respect of any event described in Section 5.1 hereof if Warrantholders are entitled to participate
in such event on the same terms mutatis mutandis as if Warrantholders had exercised their Warrants prior to or on the effective
date or record date, as the case may be, of such event.



(d)          No Adjustment
for Certain Events: No adjustment in the Exercise Price or in the number of Common Shares purchasable upon the exercise of
Warrants shall be made pursuant to Section 5.1 hereof in respect of the issue from time to time of Common Shares pursuant to this
Indenture or pursuant to any stock option, stock purchase or stock bonus plan in effect from time to time for directors, officers
or employees of the Corporation and/or any Subsidiary of the Corporation and any such issue, and any grant of options in connection
therewith, shall be deemed not to be a Common Share Reorganization, a Rights Offering nor any other event described in Section
5.1 hereof.



(e)          Other Actions:
If at any time after the Effective Date but prior to the Expiry Date the Corporation shall take any action affecting the Common
Shares, other than an action described in Section 5.1 hereof, which in the opinion of the Directors acting in good faith would
materially affect the rights of Warrantholders, either or both the Exercise Price and the number of Common Shares purchasable upon
exercise of Warrants shall be adjusted in such manner and at such time by action by the Directors, acting in good faith in their
sole discretion, but subject to the prior written consent, if required, of any stock exchange upon which the Common Shares or Warrants
may be listed, as may be equitable in the circumstances. Failure of the taking of action by the Directors so as to provide for
an adjustment prior to the effective date of any action by the Corporation affecting the Common Shares shall be deemed to be conclusive
evidence that the Directors have determined that it is equitable to make no adjustment in the circumstances.



(f)          Abandonment
of Event: If the Corporation shall set a record date to determine the holders of Common Shares for the purpose of entitling
such holders to receive any dividend or distribution or any subscription or purchase rights and shall, thereafter and before the
distribution to such Shareholders of any such dividend, distribution or subscription or purchase rights, legally abandon its plan
to pay or deliver such dividend, distribution or subscription or purchase rights, then no adjustment in the Exercise Price or the
number of Common Shares purchasable upon exercise of any Warrant shall be required by reason of the setting of such record date.



- 30 -







(g)          Deemed Record
Date: In the absence of a resolution of the Directors fixing a record date for a Common Share Reorganization, a Rights Offering
or a Special Distribution, the Corporation shall be deemed to have fixed as the record date therefor the earlier of the date on
which holders of record of Common Shares are determined for the purpose of participating in the Common Share Reorganization, Rights
Offering or Special Distribution and the date on which the Common Share Reorganization, Rights Offering or Special Distribution
becomes effective.



(h)          Disputes:
If a dispute shall at any time arise with respect to adjustments of the Exercise Price or the number of Common Shares purchasable
upon exercise of Warrants, such disputes shall be conclusively determined by the Corporation's Auditors or if they are unable or
unwilling to act, by such other firm of independent chartered accountants as may be selected by action by the Directors and acceptable
to the Warrant Agent and any such determination shall be conclusive evidence of the correctness of any adjustment made under Section
5.1 hereof and shall be binding upon the Corporation, the Warrant Agent and the Warrantholders. Such auditors or accountants shall
be provided access to all necessary records of the Corporation for the purpose of such determination. In the event any determination
is made, the Corporation shall deliver a Certificate of the Corporation to the Warrant Agent describing such determination.



(i)          Corporate Affairs:
As a condition precedent to the taking of any action which would require any adjustment in any of the subscription rights pursuant
to the Warrants, including the Exercise Price and the number or class of shares or other securities 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 may validly and legally issue as fully paid and non-assessable all the shares or other securities which all holders
of Warrants are entitled to receive in accordance with the provisions thereof.



| | 5.3 | Postponement of Subscription:
| | --- | -----------------------------



In any case in which this Article 5 shall
require that an adjustment shall be effective immediately after a record date for an event referred to herein, the Corporation
may defer, until the occurrence of such event:



(a)          issuing to the
holder of any Warrant, to the extent that Warrants are exercised after such record date and before the occurrence of such event,
the additional Common Shares or other securities issuable upon such exercise by reason of the adjustment required by such event;
and



(b)          delivering to
such holder any distribution declared with respect to such additional Common Shares or other securities after such exercise date
and before such event;



provided however, that
the Corporation shall deliver to such holder an appropriate instrument evidencing the right of such holder upon the occurrence
of the event requiring the adjustment, to an adjustment in the Exercise Price or the number of Common Shares purchasable on the
exercise of any Warrant and to such distributions declared with respect to any additional Common Shares issuable on the exercise
of any Warrant.

| | ---- | ----------------------------------------------------------------------------------------------------



Where a notice pursuant to this Section
5.4 has been given, the Warrant Agent shall be entitled to act and rely on any adjustment calculation of the Corporation or of
the Corporation’s Auditors.



(c)          Duty of Warrant
Agent: Subject to Section 11.2(a) hereof, the Warrant Agent shall not:



| | (i) | at any time be under any duty or responsibility to any Warrantholder to determine whether any facts
exist which may require any adjustment in the Exercise Price or number of Common Shares issuable upon the exercise of the Warrants,
or with respect to the nature or extent of any such adjustment when made, or which respect to the method employed in making such
adjustment;

of the provisions of this Indenture or relieving the Corporation from any of the obligations, conditions or restrictions herein
contained, provided that in the opinion of the Warrant Agent, relying on the opinion of Counsel,, no such modification or relief
shall be or become operative or effective in such manner as to impair any of the rights of the Warrantholders or of the Warrant
Agent and provided further that the Warrant Agent may in its sole discretion decline to enter into any such supplemental indenture
which in its opinion may not afford adequate protection to the Warrant Agent when the same shall become operative; or



(i)           any other purpose
not inconsistent with the terms of this Indenture, including the correction or rectification of any ambiguities, defective provisions,

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



(b)          Applicable
Legislation: The Corporation and the Warrant Agent agree that each of them will at all times in relation to this Indenture
and any action to be taken hereunder observe and comply with, and be entitled to the benefits of, Applicable Legislation.



| | 11.2 | Rights and Duties of Warrant Agent:
| | ---- | -----------------------------------



(a)           Degree of
Skill: In the exercise of the rights and duties prescribed or conferred by the terms of this Indenture, the Warrant Agent shall
act honestly and in good faith with a view to the best interests of the Warrantholders and shall exercise that degree of care,
diligence and skill that a reasonably prudent warrant agent would exercise in comparable circumstances. No provision of this Indenture
shall be construed to relieve the Warrant Agent from liability for its own grossly negligent action, its own grossly negligent
failure to act or its own wilful misconduct or bad faith.



- 43 -







(b)           Conditions
for Action: Subject to Section 11.2(a) hereof, the Warrant Agent shall not be bound to do anything or take any act or action
for the enforcement of any of the obligations of the Corporation under this Indenture unless and until the Warrant Agent shall
have received a Warrantholders' Request setting out the action which the Warrant Agent is required to take and the obligation of
the Warrant Agent to commence or continue any act, action or proceeding for the purpose of enforcing any rights of the Warrant
Agent or the Warrantholders hereunder shall be conditional upon the Warrantholders furnishing, when required by notice by the Warrant
Agent, sufficient funds to commence or continue such act, action or proceeding and an indemnity reasonably satisfactory to the
Warrant Agent to protect and hold harmless the Warrant Agent against the costs, charges, expenses and liabilities to be incurred
thereby and any loss or damage it may suffer by reason thereof. None of the provisions contained in this Indenture shall require
the Warrant Agent to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties
or in the exercise of any of its rights or powers unless indemnified as aforesaid.



The Warrant Agent shall
not 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.



(c)           Deposit of
Warrant Certificates: The Warrant Agent may, before commencing or at any time during the continuance of any act, action or
proceeding for the purpose of enforcing any rights of the Warrant Agent or the Warrantholders hereunder, require the Warrantholders
at whose instance it is acting to deposit with the Warrant Agent the Warrant Certificates held by them, for which Warrant Certificates
the Warrant Agent shall issue receipts.



(d)           Supremacy
of Applicable Legislation: Every provision of this Indenture that by its terms relieves the Warrant Agent of liability or entitles
it to rely upon any evidence submitted to it is subject to the provisions of Applicable Legislation and of this Article 11.



| | 11.3 | Evidence:
| | ---- | ---------



(a)           Entitlement
to Rely on Evidence: Whenever it is provided in this Indenture that the Corporation shall deposit with the Warrant Agent resolutions,
certificates, reports, opinions, requests, orders or other documents, it is intended that the truth, accuracy and good faith on
the effective date thereof of the facts and opinions stated in all documents so deposited shall, in each and every such case, be
conditions precedent to the right of the Corporation to have the Warrant Agent take the action to be based thereon. The Warrant
Agent may rely and shall be protected in acting upon any such documents deposited with it in purported compliance with any such
provision or for any other purpose hereof, but may, in its discretion, require further evidence before acting or relying thereon.
The Warrant Agent may also rely and shall be protected in acting upon any resolution, certificate, statement, instrument, opinion,
report, notice, request, consent, order, letter, telegram, cablegram or other paper or document believed by it to be genuine and
to have been signed, sent or presented by or on behalf of the proper party or parties.



- 44 -







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



(c)          Statutory
Declarations: Whenever Applicable Legislation requires that evidence referred to in Section 11.3(a) hereof be in the form of
a statutory declaration, the Warrant Agent may accept such statutory declaration in lieu of a Certificate of the Corporation required
by any provision hereof. Any such statutory declaration may be made by (a) the Chief Executive Officer or any Director of the Corporation
and, in addition, by (b) the Chief Financial Officer or any Director of the Corporation.



(d)          Proof of Execution:
Proof of execution of an instrument in writing by any Warrantholder may be made by the certificate of a notary public, or other
officer with similar powers, that the person signing such instrument acknowledged to him the execution thereof, or by an affidavit
of a witness to such execution or in any other manner which the Warrant Agent may consider adequate and in respect of a corporate
Warrantholder, shall include a certificate of incumbency of such Warrantholder together with a certified copy of the resolution
of its board of directors authorizing the person who signs such instrument to sign such instrument



| | 11.4 | Experts and Advisers:
| | ---- | ---------------------



The Warrant Agent may employ or retain,
at the expense of the Corporation, such counsel, accountants or other experts or advisers as it may reasonably require for the
purpose of determining and discharging its duties hereunder, may pay reasonable remuneration for all services performed by any
of them without taxation of any costs of any counsel and shall not be responsible for any misconduct on the part of any of them.
The Warrant Agent may act and shall be protected in acting in good faith on the opinion or advice of or information obtained from
any counsel, accountant or other expert or adviser, whether retained or employed by the Corporation or by the Warrant Agent, in
relation to any matter arising in relation to this Indenture.



| | 11.5 | Warrant Agent not Required to give Security:
| | ---- | --------------------------------------------



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



| | 11.6 | Protection of Warrant Agent:

(a)          Protection:
By way of supplement to the provisions of any law for the time being relating to warrant agents, it is expressly declared and agreed

this Indenture or in the Warrant Certificates (except the representation contained in Section 11.8 hereof and in the countersignature

shall be deemed to be made by, the Corporation;
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- 45 -







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



| | (iii) | the Warrant Agent shall not incur any liability or responsibility whatever or be in any way responsible
for the consequence of any breach on the part of the Corporation of any of the representations, warranties or covenants herein
contained or of any acts of Directors, officers, employees, agents or servants of the Corporation;
| | ----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | the Warrant Agent, in its personal or any other capacity, may buy, lend upon and deal in shares
of the Corporation and in the Warrants and generally may contract and enter into financial transactions with the Corporation or
any corporation related to the Corporation without being liable to account for any profit made thereby;
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



| | (vi) | in the event that any of the funds provided to the Warrant Agent hereunder are received by it in
the form of an uncertified cheque or bank draft, the Warrant Agent shall be entitled to delay the time for the release of such
funds and the related Common Shares acquired upon the exercise of any Warrants until such uncertified cheque or bank draft has
cleared the financial institution upon which the same is drawn.
| | ---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (vii) | The Warrant Agent shall not be liable for any error in judgment or for any act done or step taken
or omitted by it in good faith or for any mistake, in fact or law, or for anything which it may do or refrain from doing in connection
herewith except arising out of its own gross negligence, bad faith or willful misconduct.
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



(b)          Indemnity:
In addition to and without limiting any protection of the Warrant Agent hereunder or otherwise by law, the Corporation agrees to
indemnify the Warrant Agent and its officers, directors and employees and save it harmless from all liabilities, suits, damages,
costs, expenses and actions which may be brought against or suffered by it arising out of or connected with performance by it of
its duties hereunder except to the extent that such liabilities, suits, damages, costs and actions are attributable to the gross
negligence or wilful misconduct of the Warrant Agent. Notwithstanding any other provision hereof, this indemnity shall survive
any removal or resignation of the Warrant Agent, discharge of this Indenture and termination of any duties and obligations hereunder.



- 46 -







| | 11.7 | Replacement of Warrant Agent, Successor by Merger:
| | ---- | --------------------------------------------------



(a)           Resignation:
The Warrant Agent may resign its duties and obligations and be discharged from all further duties and liabilities hereunder, subject
to this Section 11.7(a), by giving to the Corporation not less than sixty (60) days prior notice in writing or such shorter prior
notice as the Corporation may accept as sufficient. The Warrantholders, by Extraordinary Resolution, shall have power at any time
to remove the 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 such Extraordinary Resolution has appointed a new warrant agent;
failing such appointment by the Corporation, the retiring Warrant Agent, at the expense of the Corporation, or any Warrantholder
may apply to a judge of the Ontario Court of Justice (General Division), on such notice as such judge may direct for the appointment
of a new warrant agent; provided that any new Warrant Agent so appointed by the Corporation or by the Court shall be subject to
removal as aforesaid by the Warrantholders. Any new warrant agent appointed under this Section 11.7(a) shall be a corporation authorized
to carry on the business of a trust company or transfer agent in the Province of Ontario and, if required by Applicable Legislation
of any other province in Canada, in such other provinces. On any such appointment the new warrant agent shall be vested with the
same powers, rights, duties and responsibilities as if it had been originally named herein as Warrant Agent without any further
assurance, conveyance, act or deed, but there shall be immediately executed, at the expense of the Corporation, all such conveyances
or other instruments as may, in the opinion of Counsel, be necessary or advisable for the purpose of assuring the same to the new
warrant agent, provided that, following any resignation or removal of the Warrant Agent and appointment of a successor warrant
agent, the successor warrant agent shall have executed an appropriate instrument accepting such appointment and, at the request
of the Corporation, upon payment of any outstanding fees, the predecessor Warrant Agent shall execute and deliver to the successor
warrant agent an appropriate instrument transferring to such successor warrant agent all rights and powers of the Warrant Agent
hereunder so ceasing to act.



(b)           Notice of
Successor: Upon the appointment of a successor warrant agent, the Corporation shall promptly notify the Warrantholders thereof
in the manner provided for in Article 12 hereof.



(c)           No Further
Act for Merger: Any corporation into which the Warrant Agent is amalgamated or with which it is consolidated or to which all
or substantially all of its corporate trust business is sold or is otherwise transferred or any corporation resulting from any
consolidation or amalgamation to which the Warrant Agent is a party shall become the successor Warrant Agent under this Indenture,
without the execution of any document or any further act; provided that such corporation would be eligible for appointment as a
successor warrant agent under Section 11.7(a) hereof.



- 47 -







Certification:
Any Warrant Certificate countersigned but not delivered by a predecessor Warrant Agent may be delivered by the successor warrant
agent in the name of the predecessor or successor warrant agent. In case at any time the name of the Warrant Agent is changed and
at such time any of the Warrant Certificates have been countersigned but not delivered, the Warrant Agent may adopt the countersignature
under its prior name and deliver Warrant Certificates so countersigned; and in case at that
time any of the Warrant Certificates have not been countersigned, the Warrant Agent may countersign such Warrant Certificates either
in its prior name or in its changed name; and in all such cases such Warrant Certificates will have the full force provided in
the Warrant Certificates and in this Indenture.



| | 11.8 | Conflict of Interest:
| | ---- | ---------------------



(a)           Representation:
The Warrant Agent represents to the Corporation that at the time of the execution and delivery hereof no material conflict of interest
exists in the Warrant Agent's role hereunder 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 duties and obligations hereunder to a successor warrant agent approved by the Corporation and meeting the requirements set
forth in Section 11.7(a) hereof.



| | 11.9 | Acceptance of Duties and Obligations:
| | ---- | -------------------------------------



The Warrant Agent hereby accepts the duties
and obligations in this Indenture declared and provided for and agrees to perform the same upon the terms and conditions hereinbefore
set forth unless and until discharged therefrom.



| | 11.10 | Actions by Warrant Agent to Protect Interest:
| | ----- | ---------------------------------------------



The Warrant Agent shall have power to institute
and to maintain such actions and proceedings as it may consider necessary or expedient to preserve, protect or enforce its interest
and the interests of the Warrantholders.



| | 11.11 | Documents, Moneys, etc. Held by Warrant Agent:
| | ----- | ----------------------------------------------



Any securities, documents of title or other
instruments that may at any time be held by the Warrant Agent subject to the duties and obligations hereof may be placed in the
deposit vaults of the Warrant Agent or of any bank listed in Schedule I of the Bank Act (Canada), as amended, or deposited
for safekeeping with any such bank. Unless herein otherwise expressly provided, any moneys so held pending the application or withdrawal
thereof under any provisions of this Indenture, may be deposited in the name of the Warrant Agent in any such bank at the rate
of interest, if any, then current on similar deposits or, with the consent of the Corporation, may be deposited in the deposit
department of the Warrant Agent or any other loan or trust company or chartered bank authorized to accept deposits under the laws
of Canada or a province thereof. All interest or other income received by the Warrant Agent in respect of such deposits and investments
shall belong to the Corporation.



- 48 -







| | 11.12 | Warrant Agent Not to be Appointed Receiver:
| | ----- | -------------------------------------------



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



| | 11.13 | Compliance with Applicable Legislation
| | ----- | --------------------------------------



The Warrant Agent shall retain the right
not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason whatsoever, the
Warrant Agent, in its sole judgement, determines that such act might cause it to be in non-compliance with any applicable anti-money
laundering or anti-terrorist legislation, regulation or guideline. Further, should the Warrant Agent, in its sole judgement, determine
at any time that its acting under this Warrant Indenture has resulted in its being in non-compliance with any applicable anti-money
laundering or anti-terrorist legislation, regulation or guideline, then it shall have the right to resign on 10 days’ written
notice to the Corporation 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.

will be excluded. Accidental failure or omission in giving notice or accidental failure to mail notice to any Warrantholder will

WARRANT



TO PURCHASE COMMON SHARES OF CYNAPSUS
THERAPEUTICS INC.



THIS IS TO CERTIFY THAT,
for value received, ___________ (the "holder") is entitled to subscribe for and
to purchase, AT ANY TIME PRIOR TO 5:00 P.M., TORONTO TIME, ON THE EXPIRY DATE (as hereinafter defined), fully paid and non-assessable
common shares ("Common Shares") of Cynapsus Therapeutics Inc. (the "Corporation") as constituted on the date
hereof (as hereinafter defined), on the basis of one Common Share for each one Warrant, at an exercise price of $0.81 (Canadian)
per Common Share, by surrendering this Warrant Certificate to the warrant agent specified below with a subscription form (FORM
1) properly completed and executed, and a certified cheque, bank draft or money order in lawful money of Canada payable to or to
the order of the Corporation, for the total purchase price of the Common Shares so subscribed for and purchased. In the event of
any conflict or inconsistency between the provisions of this Warrant Certificate and the provisions of the Warrant Indenture (as
hereinafter defined), the provisions of the Warrant Indenture shall prevail.



The Expiry Date is the
earlier of: (i) the expiration of thirty (30) days after written notice from the Corporation that the closing price of the Common
Shares on the principal stock exchange of the Corporation has been three (3) times the Offering Price for twenty (20) consecutive
Trading Days, subject to the provisions of Section 4.1(c) of the Warrant Indenture; and (ii) sixty (60) months from the Closing
Date.



The holder of this Warrant
Certificate may subscribe for and purchase less than the number of Common Shares entitled to be subscribed for and purchased on
surrender of this Warrant Certificate. If the subscription does not exhaust the Warrants represented by this Warrant Certificate,
a Warrant Certificate representing the balance of the Warrants will be issued to the holder. No Warrant Certificate representing
fractional Warrants will be issued and the holder hereof understands and agrees that such holder will not be entitled to any cash
payment or other form of compensation in respect of a fractional Warrant. By acceptance hereof, the holder expressly waives any
right to receive fractional Common Shares upon exercise hereof. If the number of Common Shares to which a Warrantholder would otherwise
be entitled upon the exercise of this Warrant Certificate is not a whole number, then the number of Common Shares to be issued
will be rounded down to the next whole number.



The principal office
of Equity Financial Trust Company (the "Warrant Agent") in the City of Toronto, Ontario, has been appointed as the office
to receive subscriptions for Common Shares and payments from holders of Warrant Certificates. This Warrant Certificate, the subscription
form (FORM 1), and a certified cheque, bank draft or money order shall be deemed to be surrendered to the Warrant Agent only upon
personal delivery thereof or, if sent by post or other means of transmission, upon receipt thereof by the Warrant Agent at the
office specified above. The Corporation may also provide for other places at which this Warrant Certificate may be surrendered
for exchange or exercise. If mail is used for delivery of a Warrant Certificate, for the protection of the holder, registered mail
should be used and sufficient time should be allowed to avoid the risk of late delivery. Subject to adjustment hereof in the events
and in the manner set forth in the Warrant Indenture hereafter mentioned and summarized below, the price payable for each Common
Share upon exercise of this Warrant Certificate shall be $0.81 (Canadian).











Certificates representing
Common Shares subscribed for and purchased will be mailed to the persons specified in the subscription form (FORM 1) at the respective
addresses specified therein or, if so specified in the subscription form (FORM 1), delivered to such persons at the office of the
Warrant Agent where the applicable Warrant Certificate was surrendered, within three Business Days after the due surrender of such
Warrant Certificate and payment as aforesaid, including any applicable taxes.



The Warrants represented
by this Warrant Certificate may only be transferred, upon compliance with the conditions prescribed in the Warrant Indenture, on
the register of transfers to be kept at the principal office of the Warrant Agent in Toronto, Ontario, by the holder or his executors,
administrators or other legal representatives or his or their attorney duly appointed by an instrument in writing in form and executed
in a manner satisfactory to the Warrant Agent and, upon compliance with such requirements and such other reasonable requirements
as the Warrant Agent may prescribe, such transfer will be duly recorded on such register of transfers by the Warrant Agent. Notwithstanding
the foregoing, the Corporation will be entitled, and may direct the Warrant Agent, to refuse to record any transfer of any Warrant
on such register if such transfer would constitute a violation of the securities laws of any jurisdiction.



This Warrant Certificate
represents warrants of the Corporation issued or issuable under the provisions of an indenture (which indenture together with all
other instruments supplemental or ancillary thereto is herein referred to as the "Warrant Indenture") dated as of April
15, 2014, between the Corporation and the Warrant Agent, to which reference is hereby made for particulars of the rights of the
holders of the Warrant Certificates, the Corporation and the Warrant Agent in respect thereof and the terms and conditions upon
which the Warrants represented hereby are issued and held, all to the same effect as if the provisions of the Warrant Indenture
were herein set forth in full, to all of which the holder of this Warrant Certificate by acceptance hereof assents, it being expressly
understood that the provisions of the Warrant Indenture and this Warrant Certificate are for the sole benefit of the Corporation,
the Warrant Agent and the Warrantholders. A copy of the Warrant Indenture may be obtained on request without charge from the secretary
of the Corporation, at 828 Richmond Street West, Toronto, Ontario M6J 1C9, telephone: 416-703-2449. Words and terms in this Warrant
Certificate with the initial letter or letters capitalized and not defined herein shall have the meanings ascribed to such capitalized
words and terms in the Warrant Indenture.



Warrants may not be exercised
by or on behalf of a person in the United States or a "U.S. person" (a "U.S. Person"), as such term is defined
in Regulation S under the United States Securities Act of 1933, as amended (the "1933 Act"), unless an exemption from
registration is available under the 1933 Act and any applicable state securities laws and the Corporation has received an opinion
of counsel of recognized standing or other evidence in form and substance reasonably satisfactory to the Corporation to such effect;
provided, however, that a Warrantholder who is an "accredited investor," as such term is defined in Rule 501(a) of Regulation
D under the 1933 Act (a "U.S. Accredited Investor"), at the time of exercise of Warrants and that purchased units ("Units"),
with each Unit comprised of one Common Share and one Warrant, in the Corporation’s private placement of Units in the United
States and to U.S. Persons will not be required to deliver an opinion of counsel or other evidence in connection with the exercise
of Warrants underlying those Units as long as the Warrantholder is a U.S. Accredited Investor and the other representations and
warranties made by such Warrantholder at the time of purchase of the Units also remain true and correct.



2.







Common
Shares issued upon exercise of Warrants to, or for the account or benefit of, a person in the United States or a U.S. Person will
contain a legend restricting transfer under United States federal and state securities laws.



Nothing
contained in this Warrant Certificate, the Warrant Indenture or otherwise shall be construed as conferring upon the holder
hereof any right or interest whatsoever as a holder of Common Shares or other shareholder of the Corporation or any other right
or interest except as herein and in the Warrant Indenture expressly provided.



The Warrant Indenture
provides for adjustments to the exercise price of the Warrants and to the number and kind of securities purchaseable upon exercise
upon the happening of certain stated events including the subdivision or consolidation of the Common Shares, certain distributions
of Common Shares or securities exchangeable for or convertible into Common Shares or of other assets or property of the Corporation,
certain offerings of rights, warrants or options and certain reorganizations.



The Warrant Indenture
provides for the giving of notice by the Corporation prior to taking certain actions specified therein. The Corporation may from
time to time purchase any of the Warrants by private contract or otherwise. Any such Warrants purchased by the Corporation shall
be cancelled.



This Warrant Certificate,
the Warrants represented by this Warrant Certificate and the Warrant Indenture shall be governed by and performed, construed and
enforced in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein.



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

Corporation has caused this Warrant Certificate to be executed by its respective authorized officers as of this            day of           ,
