		(c)	Certificated Warrants: All Warrants issued in certificated form shall be evidenced by Warrant
Certificates. Upon the issue of Warrants issued in certificated form, Warrant Certificates shall be executed by the Corporation
and delivered to the Warrant Agent, Authenticated by the Warrant Agent upon the Written Request of the Corporation and delivered
by the Warrant Agent to the Corporation or to the order of the Corporation pursuant to a Written Request of the Corporation, without
any further act of or formality on the part of the Corporation. The Warrant Certificates shall be substantially in the form of
the certificate attached hereto as Schedule A, shall be dated as of the date of issue thereof (including all replacements issued
in accordance with this Indenture), and may bear such distinguishing letters and numbers as the Corporation may, with the approval
of the Warrant Agent, prescribe. Irrespective of any adjustments required to be made by the provisions of Article Four hereof,
all replacement Warrant Certificates shall continue to express the number of Warrant Shares purchasable upon the exercise of the
Warrants represented thereby and the Exercise Price as if such Warrant Certificates were issued as of the initial date of issue
thereof pursuant hereto. Any Warrant Certificate validly issued in accordance with the terms of this Indenture in effect at the
time of issue of such Warrant Certificate shall, subject to the terms of this Indenture and applicable law, validly entitle the
holder thereof to acquire Warrant Shares, notwithstanding that the form of such Warrant Certificate may not be the form currently
required by this Indenture.
	 	 	 

		(d)	Uncertificated Warrants: Warrants issued in uncertificated form shall be evidenced by a
book position on the register of Warrantholders to be maintained by the Warrant Agent in accordance with section 2.08 hereof.
	 	 	 

		(e)	Warrants Represented by a Global Security: For the purpose of the administration of the
Warrants to be issued hereunder and notwithstanding anything to the contrary contained in this Indenture and the Warrant Certificates,
Warrants represented by a Global Security will be registered in the name of CDS, or its nominee. Subject to applicable law, Warrants
represented by a Global Security shall, unless otherwise requested by CDS or the Corporation, be issued in uncertificated form.
If Warrants represented by a Global Security are represented in certificated form, they shall be represented by a Warrant Certificate
substantially in the form of the certificate attached hereto as Schedule A, and, if so represented, such certificate shall be delivered
to CDS, or its nominee. The Global Security will be subject to the Applicable Procedures of the book-based system and to section
2.11 hereof.
	 	 	 

		(f)	Legends:
	 	 	 

		(i)	Neither the Warrants nor the Warrant Shares issuable upon exercise of the Warrants have been or
will be registered under the U.S. Securities Act or under any United States state securities laws. Each Warrant Certificate originally
issued for the benefit or account of a U.S. Purchaser, and each Warrant Certificate issued in exchange therefor or in substitution
thereof, shall bear or be deemed to bear the following legends or such variations thereof as the Corporation may prescribe from
time to time (the "U.S. Legend"):

 

"THIS WARRANT AND THE SECURITIES DELIVERABLE UPON
EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT").
THIS WARRANT MAY NOT BE EXERCISED BY OR ON BEHALF OF A U.S. PERSON OR PERSON IN THE UNITED STATES UNLESS EXEMPTIONS FROM THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT ARE AVAILABLE. "UNITED STATES" AND "U.S. PERSON" ARE AS DEFINED BY REGULATION
S UNDER THE SECURITIES ACT.

 

     

    	10

    

 

THIS WARRANT MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE
TRANSFERRED ONLY (A) TO POET TECHNOLOGIES INC. (THE "CORPORATION"), (B) OUTSIDE THE UNITED STATES IN COMPLIANCE WITH
RULE 904 OF REGULATION S UNDER THE SECURITIES ACT, (C) IN COMPLIANCE WITH THE EXEMPTION FROM THE REGISTRATION REQUIREMENTS UNDER
THE SECURITIES ACT PROVIDED BY RULE 144 OR RULE 144A THEREUNDER, IF AVAILABLE, AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES
LAWS, (D) IN ANOTHER TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES
LAWS, OR (E) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE U.S. SECURITIES ACT THAT IS AVAILABLE FOR THE RESALE OF
THE SECURITIES, PROVIDED THAT, IN THE CASE OF TRANSFERS PURSUANT TO (C) OR (D) ABOVE, THE HOLDER HAS, PRIOR TO SUCH TRANSFER, FURNISHED
TO THE CORPORATION AN OPINION OF COUNSEL OR OTHER EVIDENCE OF EXEMPTION, IN EITHER CASE REASONABLY SATISFACTORY TO THE CORPORATION."

 

provided that, if the Warrants are being sold outside the
United States in accordance with Rule 904 of Regulation S, this legend may be removed by the transferor providing a declaration
to the Warrant Agent in the form set forth in Schedule B or as the Warrant Agent or the Corporation may prescribe from time to
time; and provided, further, that, if any such securities are being sold pursuant to Rule 144 under the U.S. Securities Act, if
available, or another transaction that does not require registration under the U.S. Securities Act or applicable state securities
laws, the legend may be removed by delivery to the Warrant Agent and the Corporation of an opinion of counsel, of recognized standing
reasonably satisfactory to the Corporation that such legend is no longer required under applicable requirements of the U.S. Securities
Act and applicable state securities laws.

 

The Warrant Agent shall be entitled to request any other
documents that it may require in accordance with its internal policies for the removal of the U.S. Legend.

 

		(ii)	The certificates or other instruments representing the Warrants, and the certificates or other
instruments representing any Warrant Shares issued upon exercise of the Warrants, if issued prior to the expiration of the applicable
hold period, will bear the following legend in accordance with applicable securities legislation:

 

"UNLESS PERMITTED BY SECURITIES
LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY BEFORE JANUARY 20, 2020."

 

		(iii)	And, if required by the policies of the TSX Venture Exchange, the certificates or ownership statements
representing the Warrants or Warrant Shares issued upon the exercise of the Warrants (and any replacement certificate or ownership
statement issued prior to the expiration of the applicable hold periods), if any, will bear a legend substantially in the following
form:

 

     

    	11

    

 

"WITHOUT THE PRIOR WRITTEN APPROVAL
OF TSX VENTURE EXCHANGE AND COMPLIANCE WITH ALL APPLICABLE SECURITIES LEGISLATION, THE SECURITIES REPRESENTED BY THIS CERTIFICATE
MAY NOT BE SOLD, TRANSFERRED, HYPOTHECATED OR OTHERWISE TRADED ON OR THROUGH THE FACILITIES OF TSX VENTURE EXCHANGE OR OTHERWISE
IN CANADA OR TO OR FOR THE BENEFIT OF A CANADIAN RESIDENT UNTIL JANUARY 20, 2020."

 

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

 

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

 

Notwithstanding any other provisions of
this Indenture, in processing and registering transfers of Warrants, no duty or responsibility whatsoever shall rest upon the Warrant
Agent to determine the compliance by any transferor or transferee with the terms of the legend contained in subsection 2.01(f),
or with the relevant securities laws or regulations.

 

	Section 2.02	
Terms and Delivery of Warrants
	 	 

		(a)	Terms: Each one Warrant issued hereunder shall entitle the holder thereof to subscribe for
and purchase one Warrant Share at the Exercise Price at any time after the Issue Date until the Expiry Time, subject to subsection
2.02(c) hereof.
	 	 	 

		(b)	Delivery of Warrants: Pursuant to a Written Request of the Corporation: (i) with respect
to Warrants authorized to be issued in paragraph 2.01(a) hereof that are issued in certificated form, Warrant Certificates in definitive
form representing such Warrants shall be created and executed by the Corporation, shall be Authenticated by the Warrant Agent and
shall be delivered by the Warrant Agent to the Corporation, or to the order of the Corporation in accordance with subsection 2.01(c)
hereof; and (ii) with respect to Warrants authorized to be issued in paragraph 2.01(a) hereof that are issued in uncertificated
form, the Warrant Agent shall Authenticate such Warrants; and, in either case, the Warrant Agent shall record the name of the holder
of such Warrants on the Warrantholder register maintained by the Warrant Agent pursuant to subsection 2.08(a) hereof.

 

     

    	12

    

 

		(c)	Adjustment: The Exercise Price and the number of Common Shares which can be subscribed for
and purchased pursuant to the Warrants shall be adjusted in the events and in the manner specified in Article Four hereof.
	 	 	 

		(d)	No Fractional Warrants: No fractional Warrants shall be issued or otherwise provided for,
and a Warrantholder shall not be entitled to subscribe for or purchase a fractional Common Share or be entitled to any cash or
other consideration such holder might otherwise be entitled to based upon the holding of such Warrants. If the number of Warrants
to which a Warrantholder would otherwise be entitled is not a whole number, then the number of Warrants 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.
	 	 	 

		(e)	Splits, Combinations: Subject to section 2.07 hereof, the number of Warrants represented
by any Warrant Certificate or any Warrant Certificates may be split, combined or exchanged for a Warrant Certificate or Warrant
Certificates representing the same number of Warrants in the aggregate.
	 	 	 

		(f)	Issue of Common Shares: The Corporation shall issue Common Shares upon the exercise of Warrants
in accordance with the provisions hereof.
	 	 	 

		Section 2.03	
Warrantholder not a Shareholder

 

Nothing in this Indenture nor in the holding of a Warrant, whether
represented by a Warrant Certificate or otherwise, 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.

 

		Section 2.04	
Signing of Warrant Certificate

 

Warrant Certificates shall be signed by the Chief Executive Officer,
the Chief Operating Officer or the Chief Financial Officer of the Corporation or any Director 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 may be mechanically reproduced in facsimile and Warrant Certificates bearing such facsimile signatures
shall be binding upon the Corporation as if they had been 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 or at the date of the Authentication or delivery thereof, any Warrant
Certificate signed as aforesaid and Authenticated by the Warrant Agent shall be valid and binding upon the Corporation and the
holder thereof shall be entitled to the benefits of this Indenture.

 

	Section 2.05	Authentication by the Warrant Agent
	 	 

		(a)	Authentication of Warrant Certificates: Each Warrant Certificate shall be Authenticated
manually by the Warrant Agent. 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 Authenticated by the Warrant Agent by means of a manual signature of one or
more of its authorized signatories, 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 Authentication by the Warrant Agent shall be conclusive
evidence as against the Corporation that the Warrant Certificate so Authenticated has been duly issued hereunder and that the holder
thereof is entitled to the benefits hereof.

 

     

    	13

    

 

		(b)	Authentication of Uncertificated Warrants: The Warrant Agent shall Authenticate Uncertificated
Warrants (whether upon original issuance, exchange, registration of transfer or otherwise). No Warrant shall be considered issued
or shall be valid or obligatory or shall entitle the holder thereof to the benefits of this Indenture until it has been Authenticated
by the Warrant Agent by completing its Internal Procedures (and the Corporation shall, and hereby acknowledges that it shall, thereupon
be deemed to have duly and validly issued such Uncertificated Warrants under this Indenture) and such Authentication by the Warrant
Agent shall be conclusive evidence as against the Corporation that such Uncertificated Warrant so Authenticated has been duly issued
hereunder and that the holder or holders thereof are entitled to the benefits hereof. The register of Warrantholders shall be final
and conclusive evidence as to all matters relating to Uncertificated Warrants with respect to which this Indenture requires the
Warrant Agent to maintain records or accounts. In the case of differences between the register at any time and any other time,
the register at the later time shall be controlling, absent manifest error.
	 	 	 

		(c)	No Representation: Authentication by the Warrant Agent shall not be construed as a representation
or warranty by the Warrant Agent as to the validity of this Indenture or of the Warrant Certificates or Uncertificated Warrants
(except the due Authentication thereof) or as to the performance by the Corporation of its obligations under this Indenture, and
the Warrant Agent shall in no respect be liable or answerable for the use made of the Warrant Certificates or Uncertificated Warrants
or any of them or of the consideration therefor, except as otherwise specified herein.
	 	 	 

	Section 2.06	
Issue in Substitution for Lost Warrant Certificate
	 	 

		(a)	Substitution: In case any Warrant Certificate issued and Authenticated hereunder shall become
mutilated, lost, destroyed or stolen, the Corporation, subject to applicable law, shall issue and thereupon the Warrant Agent shall
Authenticate 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 and shall be entitled to the benefit hereof and shall rank equally in accordance
with its terms with all Warrants of the same class either issued or to be issued hereunder.
	 	 	 

		(b)	Issue of New Warrant Certificates: The applicant for the issue of a new Warrant Certificate
pursuant to subsection 2.06(a) hereof shall bear the cost of the issue thereof and in case of loss, destruction or theft shall,
as a condition precedent to the issue thereof, 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 Warrant 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.

 

     

    	14

    

 

	Section 2.07	
Exchange of Warrant Certificates
	 	 

		(a)	Exchange: Warrant Certificates issued and Authenticated hereunder representing any specified
number of Warrants to subscribe for and purchase Warrant 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 Warrant 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, or at any other place that is designated by the Corporation with the approval of
the Warrant Agent. Any Warrant Certificate tendered for exchange shall be surrendered to the Warrant Agent and cancelled by the
Warrant Agent. The Corporation shall sign and the Warrant Agent shall Authenticate all Warrant Certificates necessary to carry
out such exchanges.
	 	 	 

		(c)	Charges for Exchange: For each Warrant Certificate exchanged, the Warrant Agent, except
as otherwise herein provided, may charge the Warrantholder a reasonable amount for each new Warrant Certificate issued. Payment
for any and all taxes or governmental or other charges required to be paid shall be made by the Warrantholder requesting such exchange,
as a condition precedent thereto.
	 	 	 

	Section 2.08	
Registration and Transfer of Warrants
	 	 

		(a)	Register: The Corporation will cause to be kept by the Warrant Agent at its principal office
in Toronto, Ontario:
	 	 	 

		(i)	a register of holders in which shall be entered in alphabetical order the name and address of each
holder of Warrants, whether Certificated Warrants or Uncertificated Warrants, the date of Authentication thereof and the number
of Warrants held by such holder;
	 	 	 

		(ii)	if represented by a Warrant Certificate, the unique number or code assigned to and imprinted thereon
and, if an Uncertificated Warrant, the unique number or code assigned thereto, if any;
	 	 	 

		(iii)	whether any of such Warrants have been cancelled; and
	 	 	 

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

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

 

     

    	15

    

 

		(c)	Valid Transfers: No transfer of any Warrant will be valid unless entered on the appropriate
register of transfers referred to in subsection 2.08(a) hereof, or on any branch registers maintained pursuant to subsection 2.08(h)
hereof, upon in the case of a Certificated Warrant, surrender to the Warrant Agent of the Warrant Certificate representing such
Warrant, duly endorsed by, or accompanied by a written instrument of transfer in the form attached to the Warrant Certificate,
or in such other 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 in form and executed satisfactory
to the Warrant Agent and upon compliance with the above requirements, such other reasonable requirements as the Warrant Agent may
prescribe and all applicable securities legislation and requirements of regulatory authorities, such transfer will be recorded
on the appropriate register of transfers by the Warrant Agent. In the case of a Warrant represented by a Global Security, any transfer
of Warrants is to be completed in accordance with the procedures described in Section 2.11 hereof and all applicable securities
legislation and requirements of regulatory authorities. In the case of the transfer of a Certificated Warrant, upon compliance
with such requirements, the Warrant Agent shall issue a Warrant Certificate to the transferee of the Certificated Warrant representing
the Warrants so transferred.
	 	 	 

		(d)	Register of Transfers: The transferee of any Warrant will, upon compliance with the requirements
of subsection 2.08(c) hereof (and, as applicable, subsection 2.08(j) 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 subsection
2.08(a) hereof, or on any branch registers of holders maintained pursuant to subsection 2.08(h) 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, except in respect of equities of which the Corporation is required to take notice by statute or by order of a court
of competent jurisdiction.
	 	 	 

		(e)	Refusal of Registration: The Corporation will be entitled, and may direct the Warrant Agent,
to refuse to recognize any transfer, or enter the name of any transferee, of any Warrant on the registers referred to in subsection
2.08(a) hereof, or on any branch registers maintained pursuant to subsection 2.08(h) 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.
	 	 	 

		(f)	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.

 

     

    	16

    

 

		(g)	Inspection: The registers referred to in subsection 2.08(a) hereof, and any branch registers
maintained pursuant to subsection 2.08(h) 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.
	 	 	 

		(h)	Location of Registers: The Corporation may at any time and from time to time change the
place at which the registers referred to in subsection 2.08(a) hereof are kept, cause branch registers of holders or transfers
to be kept at other places and close such branch 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 Eleven hereof.
	 	 	 

		(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
proffered 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.
	 	 	 

		(j)	Transfer of Warrant Certificate Bearing U.S. Warrant Legend: If a Warrant Certificate tendered
for transfer bears the U.S. Legend, the Warrant Agent shall not register such transfer unless the transferor has provided the Warrant
Agent with the Warrant Certificate and: (A) the transfer is to the Corporation; (B) the transfer is made outside of the United
States in accordance with the requirements of Rule 904 of Regulation S in circumstances where Rule 905 of Regulation S does not
apply and in compliance with applicable local laws and regulations, and the transferor delivers to the Warrant Agent a declaration
substantially in the form set forth in ‎Schedule B to this Warrant Indenture, or in such other form the Corporation may from
time to time prescribe, together with such other evidence of the availability of an exemption (which may, without limitation, include
an opinion of counsel, of recognized standing reasonably satisfactory to the Corporation and the Warrant Agent) as the Warrant
Agent may reasonably require; (C) the transfer is made in compliance with the exemption from the registration requirements of the
U.S. Securities Act provided by Rule 144 or Rule 144A thereunder, if available, and in each case in accordance with applicable
state securities laws or "blue sky" laws; (D) the transfer is made in another transaction that does not require registration
under the U.S. Securities Act or any applicable state securities laws; or (E) the transfer is made pursuant to an effective registration
statement under the U.S. Securities Act that is available for the resale of the Warrants, provided that, it has prior to any transfer
under (C) or (D) above furnished to the Corporation an opinion of counsel in form and substance reasonably satisfactory to the
Corporation to such effect. In relation to a transfer under (C) or (D) above, unless the Corporation receives an opinion of counsel,
of recognized standing, in form and substance reasonably satisfactory to the Corporation to the effect that the U.S. Legend is
no longer required on the Warrant Certificates representing the transferred Warrants, the Warrant Certificates received by the
transferee will continue to bear the U.S. Legend.

 

     

    	17

    

 

	Section 2.09	
Ownership of Warrants
	 	 

		(a)	Owner: Subject to applicable law, the Corporation and the Warrant Agent may deem and treat
the Person in whose name any Warrant is registered on the register of Warrantholders to be maintained by the Warrant Agent in accordance
with subsection 2.08(a) hereof 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: Subject to applicable law, 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 Warrant 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.
	 	 	 

	Section 2.10	
Warrants to Rank Pari Passu
	 	 

All Warrants shall rank pari passu, whatever may be the actual
date of issue of any Warrants.

 

	Section 2.11	
Book-Based System Warrants
	 	 

		(a)	Registration of beneficial interests in and transfers of Warrants held by CDS shall be made through
the book-based system, subject to Applicable Procedures, and no Warrant Certificates shall be issued in respect of such Warrants
except as set out in this section 2.11, where physical certificates evidencing ownership in such securities are required or as
may be requested by CDS from time to time. Warrants in the book-based system shall be evidenced by a Global Security as contemplated
in subsection 2.01(e) hereof.
	 	 	 

		(b)	For so long as Warrants are represented by a Global Security, if any of the following events occurs:
	 	 	 

		(i)	CDS notifies the Corporation that it is unwilling or unable to continue as depository of the Warrants
represented by a Global Security and the Corporation is unable to identify and engage a qualified successor,
	 	 	 

		(ii)	the Corporation determines that CDS is no longer willing, able or qualified to discharge properly
its responsibilities as depository of the Warrants represented by a Global Security and the Corporation is unable to identify and
engage a qualified successor,

 

     

    	18

    

 

		(iii)	CDS ceases to be a clearing agency or otherwise ceases to be eligible to be a depository and the
Corporation is unable to locate a qualified successor, or
	 	 	 

		(iv)	the Corporation or CDS is required by applicable laws to take the action contemplated in this subsection
2.11(b),
	 	 	 

Warrant Certificates shall be issued in
exchange for the Global Security, or the applicable portion thereof, in accordance with section 2.08 hereof but subject to the
provisions of this section 2.11. All such Warrant Certificates issued and exchanged pursuant to this subsection 2.11(b) 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 Global
Security so exchanged, and the Global Security so exchanged, or the applicable portion thereof, shall be cancelled by the Warrant
Agent.

 

		(c)	All references herein to actions by, notices given or payments made to Warrantholders shall, where
Warrants are held through a Global Security, refer to actions taken by, or notices given or payments made to, CDS upon instruction
from CDS Participants in accordance with Applicable Procedures. For the purposes of any provision hereof requiring or permitting
actions with the consent of or at the direction of Warrantholders evidencing a specified percentage of the aggregate Warrants outstanding,
such direction or consent may be given by Beneficial Owners acting through CDS and the CDS Participants owning Warrants evidencing
the requisite percentage of the Warrants. The rights of Beneficial Owners shall be limited to those established by applicable laws
and agreements between CDS and the CDS Participants and between such CDS Participants and Beneficial Owners and must be exercised
through a CDS Participant in accordance with the Applicable Procedures.
	 	 	 

		(d)	Each of the Warrant Agent and the Corporation may deal with CDS for all purposes as the authorized
representative of the respective Warrantholders who are Beneficial Owners and such dealing with CDS shall constitute satisfaction
or performance, as applicable, of their respective obligations hereunder. For so long as Warrants are represented by a Global Security,
if any notice or other communication is required to be given to Warrantholders, the Warrant Agent will give such notices and communications
to CDS or its nominee.
	 	 	 

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

EXERCISE OF WARRANTS

 

	Section 3.01	
Method of Exercise of Warrants
	 	 

		(a)	Exercise: Subject to subsection 3.01 hereof, the holder of any Warrant may exercise the
right thereby conferred on such holder to subscribe for and purchase Warrant Shares by surrendering, during regular business hours
of the Warrant Agent at its offices in the City of Toronto, Ontario, after the date of issue of the Warrant but prior to the Expiry
Time, to the Warrant Agent at the place specified in subsection 3.01(d) hereof or any other place or places that may be designated
by the Corporation with the approval of the Warrant Agent, the Warrant Certificate, with a properly completed and executed subscription
form in substantially the form contained on the Warrant Certificate, together with a certified cheque, bank draft or money order
in lawful money of Canada payable to or to the order of the Corporation 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, together with the certified cheque, bank draft or money order, 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 subsection 3.01(d) hereof or any such other place designated by the Corporation
with the approval of the Warrant Agent.
	 	 	 

		(b)	Exercise by Beneficial Owner: No Warrant represented by a Global Security may be exercised
unless, prior to such exercise, the holder of such Warrant shall have taken all other action necessary to exercise such Warrant
in accordance with this Indenture and the Applicable Procedures. Notwithstanding anything to the contrary contained herein and
subject to the Applicable Procedures in force from time to time, a Beneficial Owner of Warrants represented by a Global Security
who desires to exercise his or her Warrants must do so by causing a CDS Participant to deliver to CDS, on behalf of the Beneficial
Owner, a written notice of the Beneficial Owner's intention to exercise Warrants in a manner acceptable to CDS. Forthwith upon
receipt by CDS of such notice, as well as payment in an amount equal to the product obtained by multiplying the Exercise Price
by the number of Warrant Shares subscribed for, CDS shall deliver to the Warrant Agent a Confirmation. An electronic exercise of
the Warrants initiated by a CDS Participant through a book based registration system, including CDSX, shall constitute a representation
to both the Corporation and the Warrant Agent that the Beneficial Owner at the time of exercise of such Warrants: (a) is not present
in the United States; (b) is not a U.S. Person and is not exercising such Warrants for the account or benefit of a U.S. Person
or a person in the United States; (c) did not acquire the Warrants in the United States or on behalf of, or for the account or
benefit of a U.S. Person or a person in the United States; (d) did not execute or deliver the notice of the owner's intention to
exercise such Warrants in the United States; (e) did not request delivery in the United States of the Warrant Shares issuable upon
the exercise of the Warrants, and (f) has, in all other respects, complied with the terms of Regulation S under the U.S. Securities
Act in connection with such exercise. If the CDS Participant is not able to make or deliver the foregoing representation by initiating
the electronic exercise of the Warrants, then (i) such Warrants shall be withdrawn from the book based registration system, including
CDSX, by the CDS Participant; (ii) an individually registered Warrant Certificate shall be issued by the Warrant Agent to the Beneficial
Owner or CDS Participant and (iii) the exercise procedures set forth in subsections ‎3.01(a), 3.01(c) and 3.01(g) shall be
followed.

 

     

    	20

    

 

Payment representing the Exercise Price
must be provided to the appropriate office of the CDS Participant in a manner acceptable to it. A notice in form acceptable to
the CDS Participant and payment from such Beneficial Owner should be provided to the CDS Participant sufficiently in advance so
as to permit the CDS 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 Expiry Time. 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 causing the Transfer Agent to issue to CDS
through the book-based 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 Beneficial Owner exercising the Warrants and/or
the CDS Participant exercising the Warrants on its behalf.

 

By causing a CDS Participant to deliver
to CDS a written notice of the Beneficial Owner's intention to exercise Warrants, the Beneficial Owner shall be deemed to have
irrevocably surrendered his or her Warrants so exercised and appointed such CDS Participant to act as his or her exclusive settlement
agent with respect to the exercise and the receipt of underlying Warrant Shares in connection with the obligations arising from
such exercise.

 

Any notice of the Beneficial Owner's intention
to exercise Warrants which CDS determines to be incomplete, not in proper form or not duly executed shall for all purposes be void
and of no effect and the exercise to which it relates shall be considered for all purposes not to have been made thereby. A failure
by a CDS Participant to exercise or to give effect to the settlement thereof in accordance with the Beneficial Owner's instructions
will not give rise to any obligations or liability on the part of the Corporation or Warrant Agent to the CDS Participant or the
Beneficial Owner.

 

Any Confirmation received by the Warrant
Agent after business hours on any Business Day other than the Expiry Date will be deemed to have been received by the Warrant Agent
on the next following Business Day. The Confirmation (together with payment representing the Exercise Price for the Common Shares
for which the Warrant is being exercised) in connection with any exercise by a Beneficial Owner must be received by the Warrant
Agent prior to the Expiry Time. Any Warrant with respect to which a Confirmation (together with payment representing the Exercise
Price for the Warrant Shares for which the Warrant is being exercised) is not received by the Warrant Agent before the Expiry Time
shall be deemed to have expired and become void and all rights with respect to such Warrant shall terminate and be cancelled.

 

     

    	21

    

 

		(c)	Subscription Form Completion: Any subscription form referred to in subsection 3.01(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 Warrant Shares which the holder desires to subscribe for and purchase, such number, in the
case of the exercise of Certificated Warrants, 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 Warrant 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 where the certificates representing such Warrant Shares, or other appropriate form of evidence
of ownership, are to be sent, and (D) the number of Warrant 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. For the avoidance of doubt, Warrant Shares may only be issued to a Person or Persons other
than the Warrantholder in compliance with the terms of this Indenture and in particular subsection 2.01(f), and Section 2.08 of
this Indenture.
	 	 	 

		(d)	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 Eleven 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.
	 	 	 

		(e)	Accounting to Corporation and Disbursement of Monies: 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 disbursed to the Corporation in accordance with
this Indenture. Within five Business Days of receipt thereof the Warrant Agent shall forward to the Corporation (or to an account
or accounts of the Corporation designated in writing by the Corporation for that purpose) all monies received through the exercise
of Warrants.
	 	 	 

		(f)	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.
	 	 	 

		(g)	U.S. Warrant Exercises. In addition to completing the subscription form in substantially
the form contained on the Warrant Certificate, a U.S. Warrantholder must provide: (a) a completed and executed U.S. Warrantholder
Letter; or (b) an opinion of counsel, of recognized standing, in form and substance reasonably satisfactory to the Corporation
and the Warrant Agent, that the exercise is exempt from the registration requirements of the U.S. Securities Act and applicable
securities laws of any state of the United States.

 

     

    	22

    

 

	Section 3.02	Effect of Exercise of Warrants
	 	 

		(a)	Effect of Exercise: Upon compliance by the holder of any Warrants with the provisions of
section 3.01 hereof, but subject to the provisions of subsection 3.03(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. The Warrants so exercised will be void and of no value or effect and the Warrantholder will have no further right
thereunder, other than the right to receive Common Shares in respect of the Warrants duly exercised.
	 	 	 

		(b)	Issue of Share Certificates: As soon as practicable, and in any event no later than the
fifth 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 (A) cause to be mailed or delivered, electronically or otherwise, 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 completed subscription instruction,
or (B) if specified in such subscription instruction, 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, or any other appropriate evidence of the issuance
of Common Shares, representing or evidencing the appropriate number of Common Shares to which the Warrantholder is entitled and
elected to subscribe for and purchase pursuant to the provisions of section 3.01 hereof.
	 	 	 

	Section 3.03	Subscription for Less than Entitlement
	 	 

		(a)	Exercise for Less Than Maximum: The holder of any Warrants 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, 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 2.02 hereof,
or other appropriate evidence of Warrants in the case of Uncertificated Warrants, in respect of the balance of the Warrants which
were not then exercised.
	 	 	 

		(b)	No Fractional Common Shares: Notwithstanding any adjustment provided for in Article Four
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 3.04 hereof, the number of
Common Shares to be issued shall be rounded down to the next whole number and the holder of such Warrants shall not be entitled
to any compensation in respect of any fractional Common Share.

 

     

    	23

    

 

		Section 3.04	
Warrant Certificates for Fractions of Common Shares

 

To the extent that the holder of a Warrant 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 which in the aggregate entitles the Warrantholder to receive a whole number of Common Shares.

 

		Section 3.05	
Expiration of Warrants

 

After the Expiry Time 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.

 

	Section 3.06	
Cancellation U.S. Prohibition on Exercise; Legended Certificates
	 	 

		(a)	The Warrants and the Warrant Shares have not been and will not be registered under the U.S. Securities
Act or any state securities laws, and may not be exercised by or on behalf of, or for the account or benefit of, a U.S. Person
or a person in the United States unless an exemption from such registration requirements is available.
	 	 	 

		(b)	Warrants may not be exercised except in compliance with the requirements set forth herein, in the
Warrant Certificate and in the subscription form contained on the Warrant Certificate (FORM 1).
	 	 	 

		(c)	Warrant Shares issued upon the exercise of any Certificated Warrant (i) which bears the U.S. Legend,
(ii) other than pursuant to Box A of the subscription form contained on the Warrant Certificate (FORM 1), or (iii) or pursuant
to Box A of the subscription form contained on the Warrant Certificate in the event that the Corporation determines that Rule 905
of Regulation S applies to such issuance shall be issued in certificated form and, upon such issuance, shall bear the following
legend (the "U.S. Common Share Legend"):

 

"THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR STATE SECURITIES LAWS. THE HOLDER
HEREOF, BY PURCHASING THESE SECURITIES, AGREES FOR THE BENEFIT OF POET TECHNOLOGIES, INC. (THE "CORPORATION") THAT THESE
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 ("REGULATION S") UNDER THE SECURITIES ACT AND IN COMPLIANCE WITH APPLICABLE
CANADIAN LAWS AND REGULATIONS, (C) WITHIN THE UNITED STATES IN ACCORDANCE WITH (1) RULE 144A UNDER THE SECURITIES ACT OR (2) RULE
144 UNDER THE SECURITIES ACT AND IN COMPLIANCE WITH APPLICABLE STATE SECURITIES LAWS, (D) IN ANOTHER TRANSACTION THAT DOES NOT
REQUIRE REGISTRATION UNDER THE SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAWS; OR (E) PURSUANT TO AN EFFECTIVE REGISTRATION

AGENT. EACH PURCHASER OF THESE SECURITIES IS HEREBY NOTIFIED THAT THE SELLER OF THESE SECURITIES MAY BE RELYING ON THE EXEMPTION
FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER.

provided, that, if any such securities are being sold
outside the United States in compliance with the requirements of Rule 904 of Regulation S in circumstances where Rule 905 of Regulation
S does not apply, and in compliance with Canadian laws and regulations, the legend set forth above may be removed by providing
an executed declaration to the Corporation's registrar and transfer agent in such form as the Corporation may prescribe from time
to time; and provided, further, that, if any such securities are being sold pursuant to Rule 144 under the U.S. Securities Act,
if available, the legend may be removed by delivery to the registrar and transfer agent of the Corporation of an opinion of counsel,
of recognized standing reasonably satisfactory to the Corporation, to the effect that such legend is no longer required under applicable

(as defined in Regulation S) in the event that the Corporation determines that such affixing or marking of the U.S. Common Share
Legend is then necessary to comply with U.S. securities laws.

All Warrant Certificates surrendered or deemed to be surrendered
to the Warrant Agent pursuant to Section 2.06, Section 2.07, Section 2.08 or Section 3.01 hereof will be cancelled by the Warrant

Certificates so cancelled and the number of Warrants evidenced thereby.

ADJUSTMENTS

 

		Section 4.01	
Adjustment of Exercise Price and Number of Warrant Shares Purchasable Upon Exercise

 

The Exercise Price and the number of Warrant Shares purchasable
upon the exercise of a Warrant 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 as a stock dividend or other distribution,
other than as a Dividend Paid In The Ordinary Course,
	 	 	 

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

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

(any of such events in paragraphs 4.01(a)(i), (ii) and (iii)
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).
	 	 	 

To the extent that any adjustment in the Exercise Price
occurs pursuant to this subsection 4.01(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
subsection 4.01(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.

 

     

    	26

    

 

		(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 applicable 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
	 	 	 

		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).
	 	 	 

To the extent that any such rights, options
or warrants are not so exercised on or before the expiry thereof, the Exercise Price will be readjusted to the Exercise Price that
would then be in effect based on the number of Common Shares (or securities convertible into or exchangeable for Common Shares)
actually delivered on the exercise of such rights, options or warrants.

 

     

    	27

    

 

		(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;
	 	 	 

		(iii)	evidences of indebtedness of the Corporation; or
	 	 	 

		(iv)	any property (including cash) 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 applicable Exercise Price in effect
on the record date for the Special Distribution by a fraction:

 

		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 subsection 4.01(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 subsection 4.01(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.

 

     

    	28

    

 

		(d)	Reclassification of Common Shares; Consolidation; Arrangement; 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 (other than a Subsidiary of the Corporation);
	 	 	 

(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 theretofore 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 theretofore 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)	Adjustment to Number of Common Shares: 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 subsection 4.01(a)
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.

 

     

    	29

    

 

		(f)	Adjustments Prior to Effective Date: Notwithstanding any other provisions hereof, in the
event that, at any time prior to the Effective Date, there shall have occurred one or more events which, if any Warrant was outstanding,
would require an adjustment or adjustments thereto or to the exercise price thereof in accordance with the provisions hereof, then,
notwithstanding anything to the contrary herein and notwithstanding that no Warrants may be outstanding at the applicable time
under this Indenture, at the time of the issue of Warrants hereunder the same adjustment or adjustments in accordance with the
adjustment provisions hereof shall be made to such Warrants, mutatis mutandis, as if such Warrants were outstanding and
governed by the provisions hereof upon the occurrence of such event or events.
	 	 	 

		Section 4.02	
Rules Regarding Calculation of Adjustment of Exercise Price and Number of Common Shares Purchasable Upon Exercise

 

For the purposes of section 4.01 hereof the following subsections
shall apply:

 

		(a)	Successive Adjustments: Any adjustment made pursuant to section 4.01 hereof shall be cumulative
and made successively whenever an event referred to therein shall occur, subject to the following subsections of this section 4.02.
	 	 	 

		(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 subsection 4.02(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.
	 	 	 

		(c)	Mutatis Mutandis Adjustment: Subject to the prior written consent, if required,
of any stock exchange on which the Common Shares 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 4.01 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 4.01 hereof in respect of the issue from
time to time of Common Shares pursuant to this Indenture, pursuant to exchangeable or convertible securities of the Corporation
outstanding as of the date hereof, 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 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
4.01 hereof.

 

     

    	30

    

 

		(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 4.01 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 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 or the taking of any other action, legally abandons 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.
	 	 	 

		(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 Auditor 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 (the "Corporation's Accountants") and
any such determination shall be conclusive evidence of the correctness of any adjustment made under section 4.01 hereof and shall
be binding upon the Corporation, the Warrant Agent and the Warrantholders. Such auditor 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.

 

     

    	31

    

 

		Section 4.03	 Postponement of Subscription

 

In any case in which this Article Four 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 Warrant 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 Warrant Shares purchasable on the exercise of any Warrant and to such distributions
declared with respect to any additional Warrant Shares issuable on the exercise of any Warrant.

 

	Section 4.04	 Notice of Adjustment of Exercise Price and Number of Common Shares Purchasable Upon Exercise
	 	 

		(a)	Notice of Effective or Record Date: At least 14 days prior to the effective date or record
date, as the case may be, of any event which requires or might require an adjustment in any of the subscription rights pursuant

		(i)	the Corporation shall file with the Warrant Agent a Certificate of the Corporation specifying the
particulars of such event to the extent then known including, if determinable, the required adjustment and the computation of such
adjustment; and

for in Article Eleven hereof of the particulars of such event to the extent then known including, if determinable, the required
adjustment.
	 	 	 

		(b)	Adjustment Not Determinable: In the case where any adjustment for which a notice pursuant
to subsection 4.04(a) hereof has been given is not then determinable:
	 	 	 

		(i)	the Corporation shall promptly after such adjustment is determinable file with the Warrant Agent
a Certificate of the Corporation setting forth the computation of such adjustment; and
	 	 	 

		(ii)	within five days following receipt of the Certificate of the Corporation contemplated by paragraph
4.04(b)(i) hereof, the Warrant Agent shall give notice to the Warrantholders as provided by the Corporation in the manner provided
for in Article Eleven hereof of the adjustment.

 

     

    	32

    

 

The Warrant Agent shall be entitled to act and rely on any
certificates and other documents (including adjustment calculations) of the Corporation, the Corporation's Auditor or the Corporation's
Accountants received by it pursuant to this Article Four.

 

		(c)	Duty of Warrant Agent: Subject to subsection 10.02(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 Warrant Shares issuable upon the exercise of the Warrants,
or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed in making such
adjustment;
	 	 	 

		(ii)	be accountable with respect to the validity or value (or the kind or amount) of any Common Shares
or of any shares or other securities or property which may at any time be issued or delivered upon the exercise of any Warrant;
or
	 	 	 

		(iii)	be responsible for any failure of the Corporation to make any cash payment or to issue, transfer
or deliver Warrant Shares or share certificates upon the surrender of any Warrants for the purpose of exercise, or to comply with
any of the covenants contained in this section 4.04.

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 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 gross negligence, wilful misconduct, bad faith or fraud.
	 	 	 

		(b)	Conditions for Action: Subject to subsection 10.02(a) hereof, the Warrant Agent shall not
be bound to do any thing or take any act or action for the enforcement of any of the obligations of the Corporation under this

		(a)	Entitlement to Rely on Evidence: Whenever it is provided in this Indenture that the Corporation

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.
The Warrant Agent shall be protected in acting and relying upon any document received either in facsimile or by email of a pdf
form.
	 	 	 

		(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.

or more of the President, the Chief Executive Officer, the Chief Financial Officer, the Chief Operating Officer, any Vice-President,
the Secretary, the Treasurer, any Assistant Secretary or any Assistant Treasurer of the Corporation.

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 resolution authorizing the person who signs such instrument to sign such instrument.
	 	 	 

	Section 10.04	Experts and Advisers

evidence of the registration or filing (or renewal thereof) of this Indenture or any instrument ancillary or supplemental hereto;
and
	 	 	 

		(vi)	the Warrant Agent shall not be required to take notice of any default hereunder, unless and until

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

be the successor to the Warrant Agent hereunder without any further act on its part or any of the parties hereto, provided that

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.

execution and delivery hereof no material conflict of interest exists in the Warrant Agent's role as a warrant agent hereunder

WARRANT

TO PURCHASE COMMON SHARES OF POET TECHNOLOGIES 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 September
19, 2023 (the "Expiry Date"), fully paid and non-assessable common shares ("Common Shares") of the POET Technologies
Inc. (the "Corporation") as constituted on the date hereof, on the basis of one Common Share for each one Warrant, at
an exercise price of $0.50 per Common Share, subject to adjustment as provided herein and in the Warrant Indenture, by surrendering
this Warrant Certificate to the Warrant Agent (as hereinafter defined) 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.

 

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.

 

TSX Trust Company (the "Warrant Agent")
at its offices in the City of Toronto, Ontario, has been appointed the warrant agent 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 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 thereof in the events and in the manner set forth in the Warrant Indenture
and summarized below, the price payable for each Common Share upon exercise of this Warrant Certificate shall be $0.50.

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 in
the City of Toronto, Ontario, when the transfer books of the Corporation have been opened for five Business Days after the due
surrender of such Warrant Certificate and payment as aforesaid, including any applicable taxes.

 

This Warrant Certificate may, upon compliance
with the reasonable requirements and charges of the Warrant Agent, be divided by completing and executing FORM 2 and delivering
the Warrant Certificate to the Warrant Agent.

 

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 a warrant indenture (which indenture together with all other instruments
supplemental or ancillary thereto is herein referred to as the "Warrant Indenture") dated as of September 19, 2019, 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 Corporation at 120 Eglinton Avenue East, Suite
1107, Toronto, Ontario M4P 1E2, telephone (416) 862-7330. 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.

 

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.

 

Neither the Warrants nor the Common Shares issuable
upon exercise hereof have been or will be registered under the United States Securities Act of 1933, as amended (the "U.S.
Securities Act"), or U.S. state securities laws. The Warrants may not be exercised by a person in the United States, a U.S.
Person, a person exercising the Warrants for the account or benefit of a U.S. Person or a person in the United States, a person
executing or delivering the subscription form in the United States or a person requesting delivery in the United States of the
Common Shares issuable upon such exercise, unless (i) this Warrant and such Common Shares have been registered under the U.S. Securities
Act and the applicable laws of any such state, or (ii) an exemption from such registration requirements is available and the requirements
set forth in the subscription form (FORM 1) have been satisfied. "United States" and "U.S. Person" are as defined
in Regulation S under the U.S. Securities Act.

 

The Warrant Indenture provides for adjustments
to the exercise price of the Warrants and to the number and kind of securities purchasable 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. For more information please refer to the Warrant Indenture and in particular
Article Four of the Warrant Indenture.

 

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.

 

All dollar amounts in this Warrant Certificate
are expressed in the lawful money of Canada.

		7.	the Common Shares are "restricted securities" (as defined in Rule 144(a)(3) under the

		10.	the financial statements of the Corporation have been prepared in accordance with International

    	6.

    

 

		11.	there may be material tax consequences to the undersigned of an acquisition or holding or disposition
of the Common Shares; the Corporation gives no opinion and makes no representation with respect to the tax consequences to the
undersigned under United States federal, state, local or foreign tax law of the undersigned's acquisition, holding or disposition

RECITALS

Borrower and Bank are parties to that certain Loan and Security Agreement dated as of December 30, 2016, including by that certain First Amendment to Loan and Security Agreement dated as of August 3, 2017, as amended from time to time (the “Agreement”). The parties desire to amend the Agreement in accordance with the terms of this Amendment.

NOW, THEREFORE, the parties agree as follows:

1.The defined term “Monthly Cash Burn” in Section 1.1 of the Agreement hereby is deleted in its
entirety.

2.The following defined term in Section 1.1 of the Agreement hereby is added in its entirety as
follows:

“Second Amendment Effective Date” means April 28, 2020.

3.Section 2.2(b) of the Agreement hereby is amended and restated in its entirety to read as
follows:

“(b) Repayment. Borrower shall  make  monthly  payments  of  interest  only,  in  arrears, commencing on the first (1st) Payment Date following the Funding Date of each Term Loan, and continuing on the Payment Date of each successive month thereafter through and including the Payment Date immediately preceding the Amortization Date. Borrower agrees to pay, on the Funding Date of each Term Loan, any initial partial monthly interest payment otherwise due for the period between the Funding Date of such Term Loan and the first Payment Date thereof. Commencing on the Amortization Date, and continuing on the Payment Date of each month thereafter, Borrower shall make equal monthly payments of principal, together with applicable interest, in arrears, to Bank, as calculated by Bank (which calculations shall  be deemed correct absent manifest error) based upon: (1) the amount of such Term Loan, (2) the effective rate of interest, as determined in Section 2.4(a), and (3) a repayment schedule equal to
(i) if the Amortization Date is February 1, 2018, thirty-six (36) months and (ii) if the Amortization Date is August 1, 2018, thirty (30) months; provided, however, Borrower’s Term Loan principal payments due on May 1, 2020, June 1, 2020, and July 1, 2020 (the “Deferred Principal Payments”) shall be deferred and on August 1, 2020, the outstanding principal balance of the Term Loans, including the Deferred Principal Payments, shall re-amortize and commencing on August 1, 2020 and continuing on the Payment Date of each month thereafter, Borrower shall make equal monthly payments of principal, together with applicable interest, in arrears, to Bank, as calculated by Bank (which calculations shall be deemed correct absent manifest error) based upon: (1) the amount of such Term Loan, (2) the effective rate of interest,  as determined in Section 2.4(a), and (3) a repayment schedule equal to (i) six (6) months. All unpaid principal and accrued and unpaid interest with respect to each Term Loan is due and payable in full on the Term Loan Maturity Date. Each Term Loan may only be prepaid in accordance with Sections 2.2(c) and 2.2(d).”

4.Section 6.8 of the Agreement hereby is amended and restated in its entirety to read as follows: “6.8 Minimum Liquidity. Borrower shall maintain at all times unrestricted cash
-1-

and cash equivalents in accounts maintained with Bank, in an amount equal to or greater than  the amount of the outstanding balance of the Term Loans.”

5.Exhibit C of the Agreement hereby is replaced in its entirety by Exhibit C attached hereto.

6.No course of dealing on the part of Bank or its officers, nor any failure or  delay in the exercise  of any right by Bank, shall operate as a waiver thereof, and any single or  partial exercise of any such right shall  not preclude any later exercise of any such right. Bank’s failure at any time to require strict performance by Borrower of any provision shall not affect any right of Bank thereafter to demand strict compliance and performance. Any suspension or waiver of a right must be in writing signed by an officer of Bank.

7.Unless otherwise defined, all  initially capitalized terms in  this Amendment shall be as defined in the Agreement. The Agreement, as amended hereby, shall be and remain in full force and effect in accordance with its respective terms and hereby is ratified and confirmed in all respects. Except as expressly set forth herein, the execution, delivery, and performance of this Amendment shall not operate as a waiver of, or as an amendment of, any right, power, or remedy of Bank under the Agreement, as in effect prior to the date hereof.

8.Borrower represents and warrants that the Representations and Warranties contained in the Agreement  are true and  correct as of the date of this Amendment, and that no Event of Default has occurred and  is continuing.

b.an Officer’s Certificate with respect to incumbency and resolutions authorizing the execution and delivery of this Amendment, duly executed by each Borrower;

c.all reasonable Bank Expenses incurred through the date of this Amendment, which may be debited from any of Borrower's accounts; and
