are publicly disclosed and a copy of which is made available to the public (including the Company) not later than the date the Lock-up
Bid (as defined below) is publicly announced or if the Lock-up Bid has been made prior to the date on which such agreement is entered
into, forthwith, and in any event not later than the date following the date of such agreement) whereby the Locked-up Person agrees to
deposit or tender the Voting Shares held by the Locked-up Person to the Offeror's Take-over Bid or to any Take-over Bid made by any of

the Voting Shares to another Take-over Bid or to support another transaction (whether by way of merger, amalgamation, arrangement, reorganization

value per Voting Share to the holders of Voting Shares than the Locked-up Person otherwise would have received to pay under the Lock-up
Bid (the “Lock-up Bid Consideration”). Notwithstanding the above, the Lock-Up Agreement may require that the Superior
Offer Consideration must exceed the Lock-up Bid Consideration by a specified percentage before such withdrawal right takes effect, provided
such specified percentage is not greater than seven percent (7%);



 


(and, for greater clarity, such agreement
may contain a right of first refusal or require a period of delay to give an Offeror an opportunity to match a higher price in another
Takeover Bid or transaction and may provide for any other similar limitation on a Locked-up Person's right to withdraw Voting Shares from
the agreement, as long as the limitation does not preclude the exercise by the Locked-up Person of the right to withdraw Voting Shares
during the period of the other Take-over Bid or other transaction); and

the price or value of the consideration that such Locked-up Person would have received under the Lock-up Bid;

Voting Shares previously tendered thereto to another Take-over Bid or supports another transaction;

Article 2
- THE RIGHTS


 


		2.1.	Issue of Rights: Legend on Common Share Certificates



 


		(a)	One Right shall be issued on the Effective Date in respect of each Common Share outstanding at the Record
Time and one Right shall be issued in respect of each Common Share issued after the Record Time and prior to the earlier of the Separation
Time and the Expiration Time.



 






    	 	-17-	 



     


    

 


		(b)	Certificates representing Common Shares which are issued prior to the earlier of the Separation Time and
the Expiration Time shall evidence one Right for each Common Share represented thereby. Certificates representing Common Shares that are
issued after the Record Time but prior to the earlier of the Separation Time and the Expiration Time shall have impressed on, printed
on, written on or otherwise affixed to them a legend substantially in the following form:



 





“Until the Separation Time (defined
in the Agreement below), this certificate also evidences the holder's rights described in a Shareholder Rights Plan Agreement dated as
of January 22, 2016, and amended and extended as of May 15, 2019 (the “Agreement”) between ProMIS Neurosciences
Inc. (the “Company”) and Computershare Trust Company of Canada, as the same may from time to time be amended, the terms of
which are incorporated herein by reference and a copy of which is on file at the principal office of the Company. Under certain circumstances
set out in the Agreement, the Rights may be amended or redeemed, may expire, may become void (if, in certain circumstances, they are “Beneficially
Owned” by an “Acquiring Person”, as such terms are defined in the Agreement, or a transferee thereof) or may be evidenced
by separate certificates and no longer evidenced by this certificate. The Company will mail or arrange for the mailing of a copy of the
Agreement to the holder of this certificate without charge as soon as practicable after the receipt of a written request therefor.”


 


Certificates representing Common Shares
that are issued and outstanding at the Record Time shall evidence one Right for each Common Share evidenced thereby, notwithstanding the
absence of a legend in accordance with this Subsection 2.1(b), until the earlier of the Separation Time and the Expiration Time.


 


Registered holders of Common Shares who
have not received a share certificate and are entitled to do so on the earlier of the Separation Time and Expiration Time shall be entitled
to Rights as if such certificates had been issued and such Rights shall for all purposes hereof be evidenced by the corresponding entries
on the Company's securities register for Common Shares.


 


		2.2.	Initial Exercise Price; Exercise of Rights; Detachment of Rights



 


		(a)	Subject to Subsection 3.1(a) and adjustment
as herein set forth, each Right will entitle the holder thereof, from and after the Separation Time and prior to the Expiration Time,
to purchase one Common Share for the Exercise Price (and the Exercise Price and number of Common Shares are subject to adjustment
as set forth below). Notwithstanding any other provision of this Agreement, any Rights held by the Company or any of its Subsidiaries
shall be void.



 


		(b)	Until the Separation Time:



 


		(i)	the Rights shall not be exercisable and no Right may be exercised; and



 






    	 	-18-	 



     


    

 


		(ii)	for administration purposes, each Right will be evidenced by the certificate for the associated Common
Share registered in the name of the holder thereof (which certificate shall also be deemed to represent a Rights Certificate) and Will
be transferable only together with, and will be transferred by a transfer of, such associated Common Share.



 





		(c)	From and after the Separation Time and prior to the Expiration Time:



 


		(i)	the Rights shall be exercisable; and



 


		(ii)	the registration and transfer of Rights shall be separate from and independent of Common Shares.



 


Promptly following the Separation Time,
the Company will prepare and the Rights Agent will mail to each holder of record of Common Shares as of the Separation Time (other than
an Acquiring Person and, in respect of any Rights Beneficially Owned by such Acquiring Person which are not held of record by such Acquiring
Person, the holder of record of such Rights (a “Nominee”)), at such holder's address as shown by the records of the
Company (the Company hereby agreeing to furnish copies of such records to the Rights Agent for this purpose):


 


		(A)	a Rights Certificate appropriately completed, representing the number of Rights held by such holder at
the Separation Time and having such marks of identification or designation and such legends, summaries or endorsements printed thereon
as the Company may deem appropriate and as are not inconsistent with the provisions of this Agreement, or as may be required to comply
with any law, rule or regulation or with any rule or regulation of any self-regulatory organization, stock exchange or quotation
system on which the Rights may from time to time be listed or traded, or to conform to standard usage; and



 


		(B)	a disclosure statement prepared by the Company describing the Rights, provided that a Nominee shall be
sent the materials provided for in clauses (A) and (B) in respect of all Common Shares held of record by it which are not Beneficially
Owned by an Acquiring Person.



 


		(d)	Rights may be exercised, in whole or in part, on any Business Day after the Separation Time and prior
to the Expiration Time by submitting to the Rights Agent:



 


		(i)	the Rights Certificate evidencing such Rights;



 


		(ii)	an election to exercise such Rights (an “Election to Exercise”) substantially in the
form attached to the Rights Certificate appropriately completed and duly executed by the holder or his executors or administrators or
other personal representatives or his or their legal attorney duly appointed by an instrument in writing in form and executed in a manner
satisfactory to the Rights Agent; and



 






    	 	-19-	 



     


    

 


		(iii)	payment by certified cheque, banker's draft or money order payable to the order of the Company, of a sum
equal to the Exercise Price multiplied by the number of Rights being exercised and a sum sufficient to cover any transfer tax or charge
which may be payable in respect of any transfer involved in the transfer or delivery of Rights Certificates or the issuance or delivery
of certificates for Common Shares in a name other than that of the holder of the Rights being exercised.



 


		(e)	Upon receipt of a Rights Certificate, together with a completed Election to Exercise executed in accordance
with Subsection 2.2(d)(ii), which does not indicate that such Right is null and void as provided by Subsection 3.1(b), and payment as
set forth in Subsection 2.2(d)(iii), the Rights Agent (unless otherwise instructed by the Company in the event that the Company is of
the opinion that the Rights cannot be exercised in accordance with this Agreement) will thereupon promptly:



 


		(i)	requisition from the Company's transfer agent certificates representing the number of such Common Shares
to be purchased (the Company hereby irrevocably authorizing its transfer agent to comply with all such requisitions);



 


		(ii)	when appropriate, requisition from the Company the amount of cash to be paid in lieu of issuing fractional
Common Shares in accordance with Subsection 5.5(b);



 


		(iii)	after receipt of the certificates referred to in Clause 2.2(e)(i), deliver the same to or upon the order
of the registered holder of such Rights Certificates, registered in such name or names as may be designated by such holder;



 


		(iv)	when appropriate, after receipt, deliver the cash referred to in Subsection 2.2(e)(ii) to or to the
order of the registered holder of such Rights Certificate; and



 


		(v)	tender to the Company all payments received on exercise of Rights.



 


		(f)	In case the holder of any Rights shall exercise less than all the Rights evidenced by such holder's Rights
Certificate, a new Rights Certificate evidencing the Rights remaining unexercised (subject to the provisions of Subsection 5.5(a)) will
be issued by the Rights Agent to such holder or to such holder's duly authorized assigns.



 






    	 	-20-	 



     


    

 


		(g)	The Company covenants and agrees that it will:



 


		(i)	take all such action as may be necessary and within its power to ensure that all Common Shares delivered
upon exercise of Rights shall, at the time of delivery of the certificates for such Common Shares (subject to payment of the Exercise
Price), be duly and validly authorized, executed, issued and delivered as fully paid and non-assessable;



 


		(ii)	use reasonable efforts to cause all Common Shares issued upon exercise of Rights to be listed on the principal
stock exchanges on which such Common Shares were traded immediately prior to the Stock Acquisition Date;



 


		(iii)	cause to be reserved and kept available out of the authorized and unissued Common Shares, the number of
Common Shares that, as provided in this Agreement, will from time to time be sufficient to permit the exercise in full of all outstanding
Rights;



 


		(iv)	pay when due and payable, if applicable, any and all federal, provincial and municipal transfer taxes
and charges (not including any income or capital taxes of the holder or exercising holder or any liability of the Company to withhold
tax) which may be payable in respect of the original issuance or delivery of the Rights Certificates, or certificates for Common Shares
to be issued upon exercise of any Rights, provided that the Company shall not be required to pay any transfer tax or charge which may
be payable in respect of any transfer involved in the transfer or delivery of Rights Certificates or the issuance or delivery of certificates
for Common Shares in a name other than that of the holder of the Rights being transferred or exercised; and



 


		(v)	after the Separation Time, except as permitted by Section 5.1, not take (or permit any Subsidiary
to take) any action if at the time such action is taken it is reasonably foreseeable that such action will diminish substantially or otherwise
eliminate the benefits intended to be afforded by the Rights.



 


		2.3.	Adjustments to Exercise Price; Number of Rights



 


The Exercise Price, the number
and kind of securities subject to purchase upon exercise of each Right and the number of Rights outstanding are subject to adjustment
from time to time as provided in this Section 2.3 or Article 3.


 


		(a)	In the event the Company shall at any time after the date of this Agreement:



 


		(i)	declare or pay a dividend on Common Shares payable in Common Shares (or other securities exchangeable
for or convertible into or giving a right to acquire Common Shares or other securities of the Company) other than pursuant to any optional
stock dividend program;



 


		(ii)	subdivide or change the then outstanding Common Shares into a greater number of Common Shares;



 






    	 	-21-	 



     


    

 


		(iii)	consolidate or change the then outstanding Common Shares into a smaller number of Common Shares; or



 


		(iv)	issue any Common Shares (or other securities
exchangeable for or convertible into or giving a right to acquire Common Shares or other securities of the Company) in respect of, in
lieu of or in exchange for existing Common Shares except as otherwise provided in this Section 2.3, the Exercise Price and
the number of Rights outstanding, or, if the payment or effective date therefor shall occur after the Separation Time, the securities
purchasable upon exercise of Rights shall be adjusted as of the payment or effective date in the manner set forth below:



 


		(A)	If the Exercise Price and number of Rights outstanding are to be adjusted:



 


		(1)	the Exercise Price in effect after such adjustment will be equal to the Exercise Price in effect immediately
prior to such adjustment divided by the number of Common Shares (or other capital stock) that a holder of one Common Share immediately
prior to such dividend, subdivision, change, consolidation or issuance would hold immediately thereafter as a result thereof (for the
purpose of this Agreement, “Expansion Factor” shall mean the number of Common Shares (or other capital stock) that
a holder of one Common Share immediately prior to such dividend, subdivision, change, consolidation or issuance would hold immediately
thereafter as a result thereof divided by one Common Share); and



 


		(2)	each Right held prior to such adjustment will become that number of Rights equal to the Expansion Factor,



 


and the adjusted number of Rights will be deemed
to be distributed among the Common Shares with respect to which the original Rights were associated (if they remain outstanding) and the
shares issued in respect of such dividend, subdivision, change, consolidation or issuance, so that each such Common Share (or other capital
stock) will have exactly one Right associated with it.


 


For greater certainty, if the securities purchasable
upon exercise of Rights are to be adjusted, the securities purchasable upon exercise of each Right immediately after such adjustment will
be the securities that a holder of the securities purchasable upon exercise of one Right immediately prior to such dividend, subdivision,
change, consolidation or issuance would hold immediately thereafter, including as a result of such dividend, subdivision, change, consolidation
or issuance.


 


If, after the Record Time and prior to the Expiration
Time, the Company shall issue any shares of capital stock other than Common Shares in a transaction of a type described in Subsections
2.3(a)(i) or (iv), shares of such capital stock shall be treated herein as nearly equivalent to Common Shares as may be practicable
and appropriate under the circumstances and the Company and the Rights Agent agree to amend this Agreement in order to effect such treatment.
If an event occurs which would require an adjustment under both this Section 2.3 and Subsection 3.1(a) hereof, the adjustment
provided for in this Section 2.3 shall be in addition to and shall be made prior to any adjustment required pursuant to Subsection
3.1(a) hereof. Adjustments pursuant to this Subsection 2.3(a) shall be made successively, whenever an event referred to in this
Subsection 2.3(a) occurs.


 






    	 	-22-	 



     


    

 





In the event the Company shall at any time after
the Record Time and prior to the Separation Time issue any Common Shares otherwise than in a transaction referred to in this Subsection
2.3(a), each such Common Share so issued shall automatically have one new Right associated with it, which Right shall be evidenced by
the certificate representing such associated Common Share.


 


		(b)	In the event the Company shall at any time after the Record Time and prior to the Separation Time fix
a record date for the issuance of rights, options or warrants to all holders of Common Shares entitling them (for a period expiring within
45 calendar days after such record date) to subscribe for or purchase Common Shares (or securities convertible into or exchangeable for
or carrying a right to purchase Common Shares) at a price per Common Share (or, if a security convertible into or exchangeable for or
carrying a right to purchase or subscribe for Common Shares, having a conversion, exchange or exercise price, including the price required
to be paid to purchase such convertible or exchangeable security or right per share) less than 90% of the Market Price per Common Share
on such record date, the Exercise Price to be in effect after such record date shall be determined by multiplying the Exercise Price in
effect immediately prior to such record date by a fraction:



 


		(i)	the numerator of which shall be the number of Common Shares outstanding on such record date, plus the
number of Common Shares that the aggregate offering price of the total number of Common Shares so to be offered (and/or the aggregate
initial conversion, exchange or exercise price of the convertible or exchangeable securities or rights so to be offered, including the
price required to be paid to purchase such convertible or exchangeable securities or rights) would purchase at such Market Price per Common
Share; and



 


		(ii)	the denominator of which shall be the number of Common Shares outstanding on such record date, plus the
number of additional Common Shares to be offered for subscription or purchase (or into which the convertible or exchangeable securities
or rights so to be offered are initially convertible, exchangeable or exercisable).



 


In case such subscription price may
be paid by delivery of consideration, part or all of which may be in a form other than cash, the value of such consideration shall be
as determined in good faith by the Board of Directors, whose determination shall be described in a statement filed with the Rights Agent
and shall be binding on the Rights Agent and the holders of Rights. Such adjustment shall be made successively whenever such a record
date is fixed, and in the event that such rights, options or warrants are not so issued, or if issued, are not exercised prior to the
expiration thereof, the Exercise Price shall be readjusted to the Exercise Price which would then be in effect if such record date had
not been fixed, or to the Exercise Price which would be in effect based upon the number of Common Shares (or securities convertible into,
or exchangeable or exercisable for Common Shares) actually issued upon the exercise of such rights, options or warrants, as the case may
be.


 






    	 	-23-	 



     


    

 





For purposes of this Agreement, the
granting of the right to purchase Common Shares (whether from treasury or otherwise) pursuant to any Dividend Reinvestment Plan or any
employee benefit, stock option or similar plans shall be deemed not to constitute an issue of rights, options or warrants by the Company;
provided, however, that, in all such cases, the right to purchase Common Shares is at a price per share of not less than 90% of the current
Market Price per share (determined as provided in such plans) of the Common Shares.


 


		(c)	In the event the Company shall at any time after the Record Time and prior to the Separation Time fix
a record date for the making of a distribution to all holders of Common Shares (including any such distribution made in connection with
a merger or amalgamation or statutory arrangement) of evidences of indebtedness, cash (other than an annual, quarterly monthly or routine
cash dividend or a dividend referred to in Subsection 2.3(a)(i),but including any dividend payable in other securities of the Company
other than Common Shares), assets or rights, options or warrants (excluding those referred to in Subsection 2.3(b)), the Exercise Price
to be in effect after such record date shall be determined by multiplying the Exercise Price in effect immediately prior to such record
date by a fraction:



 


		(i)	the numerator of which shall be the Market Price per Common Share on such record date, less the fair market
value (as determined in good faith by the Board of Directors, whose determination shall be described in a statement filed with the Rights
Agent and shall be binding on the Rights Agent and the holders of Rights), on a per share basis, of the portion of the cash, assets, evidences
of indebtedness, rights, options or warrants so to be distributed; and



 


		(ii)	the denominator of which shall be such Market Price per Common Share.



 


Such adjustments shall be made successively
whenever such a record date is fixed, and in the event that such a distribution is not so made, the Exercise Price shall be adjusted to
be the Exercise Price which would have been in effect if such record date had not been fixed.


 


		(d)	Notwithstanding anything herein to the contrary, no adjustment in the Exercise Price shall be required
unless such adjustment would require an increase or decrease of at least one per cent in the Exercise Price; provided, however, that any
adjustments which by reason of this Subsection 2.3(d) are not required to be made shall be carried forward and taken into account
in any subsequent adjustment. All calculations under Section 2.3 shall be made to the nearest cent or to the nearest ten-thousandth
of a share. Notwithstanding the first sentence of this Subsection 2.3(d), any adjustment required by Section 2.3 shall be made no
later than the earlier of:



 


		(i)	three years from the date of the transaction which gives rise to such adjustment; or



 





		(ii)	the Expiration Time.



 






    	 	-24-	 



     


    

 


		(e)	In the event the Company shall at any time after the Record Time and prior to the Separation Time issue
any shares of capital stock (other than Common Shares), of rights, options or warrants to subscribe for or purchase any such capital stock,
in a transaction referred to in Subsections 2.3(a)(i) or (iv) above, if the Board of Directors acting in good faith determines
that the adjustments contemplated by Subsections 2.3(a), (b) and (c) above in connection with such transaction will not appropriately
protect the interests of the holders of Rights, the Board of Directors may determine what other adjustments to the Exercise Price, number
of Rights and/or securities purchasable upon exercise of Rights would be appropriate and, notwithstanding Subsections 2.3(a), (b) and
(c) above, such adjustments rather than the adjustments contemplated by Subsections 2.3(a), (b) and (c) above, shall be
made. Subject to the prior consent of the holders of the Voting Shares or Rights obtained as set forth in Subsections 5.4(b) or (c),
the Company and the Rights Agent shall have authority to amend this Agreement as appropriate to provide for such adjustments.



 


		(f)	Each Right originally issued by the Company subsequent to any adjustment made to the Exercise Price hereunder
shall evidence the right to purchase, at the adjusted Exercise Price, the number of Common Shares purchasable from time to time hereunder
upon exercise of a Right immediately prior to such issue, all subject to further adjustment as provided herein.



 


		(g)	Irrespective of any adjustment or change in the Exercise Price or the number of Common Shares issuable
upon the exercise of the Rights, the Rights Certificates theretofore and thereafter issued may continue to express the Exercise Price
per Common Share and the number of Common Shares which were expressed in the initial Rights Certificates issued hereunder.



 


In any case in which this Section 2.3
shall require that an adjustment in the Exercise Price be made effective as of a record date for a specified event, the Company may elect
to defer until the occurrence of such event the issuance to the holder of any Right exercised after such record date the number of Common
Shares and other securities of the Company, if any, issuable upon such exercise over and above the number of Common Shares and other securities
of the Company, if any, issuable upon such exercise on the basis of the Exercise Price in effect prior to such adjustment; provided, however,
that the Company shall deliver to such holder an appropriate instrument evidencing such holder's right to receive such additional shares
(fractional or otherwise) or other securities upon the occurrence of the event requiring such adjustment.


 






    	 	-25-	 



     


    

 


		(h)	Notwithstanding anything contained in this Section 2.3 to the contrary, the Company shall be entitled
to make such reductions in the Exercise Price, in addition to those adjustments expressly required by this Section 2.3, as and to
the extent that in their good faith judgment the Board of Directors shall determine to be advisable, in order that any:



 





		(i)	consolidation or subdivision of Common Shares;



 


		(ii)	issuance (wholly or in part for cash) of Common Shares or securities that by their terms are convertible
into or exchangeable for Common Shares;



 


		(iii)	stock dividends; or



 


		(iv)	issuance of rights, options or warrants referred to in this Section 2.3, hereafter made by the Company
to holders of its Common Shares, shall not be taxable to such shareholders.



 


		(i)	Whenever an adjustment to the Exercise Price or a change in the securities purchasable upon exercise of
the Rights is made pursuant to this Section 2.3, the Company shall promptly and in any event, where such change or adjustment occurs
prior to the Separation Time, not later than the Separation Time:



 


		(i)	file with the Rights Agent and with each transfer agent for the Common Shares a certificate specifying
the particulars of such adjustment or change; and



 


		(ii)	cause notice of the particulars of such adjustment or change to be given to the holders of the Rights.



 


Failure to file such certificate or to
cause such notice to be given as aforesaid, or any defect therein, shall not affect the validity of such adjustment or change.


 


		2.4.	Date on Which Exercise Is Effective



 


Each Person in whose name
any certificate for Common Shares or other securities, if applicable, is issued upon the exercise of Rights shall for all purposes be
deemed to have become the holder of record of the Common Shares or other securities, if applicable, represented thereby, and such certificate
shall be dated the date upon which the Rights Certificate evidencing such Rights was duly surrendered in accordance with Subsection 2.2(d) (together
with a duly completed Election to Exercise) and payment of the Exercise Price for such Rights (and any applicable transfer taxes and other
governmental charges payable by the exercising holder hereunder) was made; provided, however, that if the date of such surrender and payment
is a date upon which the Common Share transfer books of the Company are closed, such Person shall be deemed to have become the record
holder of such shares on, and such certificate shall be dated, the next succeeding Business Day on which the Common Share transfer books
of the Company are open.


 






    	 	-26-	 



     


    

 


		2.5.	Execution, Authentication, Delivery and Dating of Rights Certificates



 


		(a)	The Rights Certificates shall be executed on behalf of the Company by its Chairman of the Board, Chief
Executive Officer, President, Chief Financial Officer, any Vice-President or its Corporate Secretary. The signature of any of these officers
on the Rights Certificates may be manual or facsimile. Rights Certificates bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have
ceased to hold such offices either before or after the countersignature and delivery of such Rights Certificates.



 


		(b)	Promptly after the Company learns of the Separation Time, the Company will notify the Rights Agent of
such Separation Time and will deliver Rights Certificates executed by the Company to the Rights Agent for countersignature, and the Rights
Agent shall manually countersign (in a manner satisfactory to the Company) and send such Rights Certificates to the holders of the Rights
pursuant to Subsection 2.2(c) hereof. No Rights Certificate shall be valid for any purpose until countersigned by the Rights Agent
as aforesaid.



 


		(c)	Each Rights Certificate shall be dated the date of countersignature thereof.



 


		2.6.	Registration, Transfer and Exchange



 


		(a)	The Company will cause to be kept a register (the “Rights Register”) in which, subject
to such reasonable regulations as it may prescribe, the Company will provide for the registration and transfer of Rights. The Rights Agent
is hereby appointed registrar for the Rights (the “Rights Registrar”) for the purpose of maintaining the Rights Register
for the Company and registering Rights and transfers of Rights as herein provided and the Rights Agent hereby accepts such appointment.
In the event that the Rights Agent shall cease to be the Rights Registrar, the Rights Agent will have the right to examine the Rights
Register at all reasonable times.



 


After
the Separation Time and prior to the Expiration Time, upon surrender for registration of transfer or exchange of any Rights Certificate,
and subject to the provisions of Subsection 2.6(c), the Company will execute, and the Rights Agent will manually countersign and
deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder's instructions, one
or more new Rights Certificates evidencing the same aggregate number of Rights as did the Rights Certificates so surrendered.


 


		(b)	All Rights issued upon any registration of transfer or exchange of Rights Certificates shall be the valid
obligations of the Company, and such Rights shall be entitled to the same benefits under this Agreement as the Rights surrendered upon
such registration of transfer or exchange.



 


		(c)	Every Rights Certificate surrendered for registration of transfer or exchange shall be duly endorsed,
or be accompanied by a written instrument of transfer satisfactory in form to the Company or the Rights Agent, as the case may be, duly
executed by the holder thereof or such holder's attorney duly authorized in writing. As a condition to the issuance of any new Rights
Certificate under this Section 2.6, the Company may require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including the reasonable fees and expenses of the Rights Agent)
connected therewith.



 






    	 	-27-	 



     


    

 






 


		2.7.	Mutilated, Destroyed, Lost and Stolen Rights Certificates



 


		(a)	If any mutilated Rights Certificate is surrendered to the Rights Agent prior to the Expiration Time, the
Company shall execute and the Rights Agent shall countersign and deliver in exchange therefor a new Rights Certificate evidencing the
same number of Rights as did the Rights Certificate so surrendered.



 


		(b)	If there shall be delivered to the Company and the Rights Agent prior to the Expiration Time:



 


		(i)	evidence to their reasonable satisfaction of the destruction, loss or theft of any Rights Certificate;
and



 


		(ii)	such security and indemnity as may be reasonably required by them to save each of them and any of their
agents harmless;



 


then, in the absence of notice to the
Company or the Rights Agent that such Rights Certificate has been acquired by a bona fide purchaser, the Company shall execute and upon
the Company's request the Rights Agent shall countersign and deliver, in lieu of any such destroyed, lost or stolen Rights Certificate,
a new Rights Certificate evidencing the same number of Rights as did the destroyed, lost or stolen Rights Certificate.


 


		(c)	As a condition to the issuance of any new Rights Certificate under this Section 2.7, the Company
may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and
any other expenses (including the reasonable fees and expenses of the Rights Agent) connected therewith.



 


		(d)	Every new Rights Certificate issued pursuant
to this Section 2.7 in lieu of any destroyed, lost or stolen Rights Certificate shall evidence the contractual obligation of the
Company, whether or not the destroyed, lost or stolen Rights Certificate shall be at any time enforceable by anyone, and shall
be entitled to all the benefits of this Agreement equally and proportionately with any and all other Rights duly issued hereunder.



 


		2.8.	Persons Deemed Owners of Rights



 


The Company, the Rights Agent
and any agent of the Company or the Rights Agent may deem and treat the Person in whose name a Rights Certificate (or, prior to the Separation
Time, the associated Common Share certificate) is registered as the absolute owner thereof and of the Rights evidenced thereby for all
purposes whatsoever and the Company and the Rights Agent shall 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. As used in this Agreement, unless the context otherwise requires, the term
 “holder” of any Rights shall mean the registered holder of such Rights (or, prior to the Separation Time, of the associated
Common Shares).


 



    -28- 


     


    

 


		2.9.	Delivery and Cancellation of Certificates



 


All Rights Certificates surrendered
upon exercise or for redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Rights Agent,
be delivered to the Rights Agent and, in any case, shall be promptly cancelled by the Rights Agent. The Company may at any time deliver
to the Rights Agent for cancellation any Rights Certificates previously countersigned and delivered hereunder which the Company may have
acquired in any manner whatsoever, and all Rights Certificates so delivered shall be promptly cancelled by the Rights Agent. No Rights
Certificate shall be countersigned in lieu of or in exchange for any Rights Certificates cancelled as provided in this Section 2.9,
except as expressly permitted by this Agreement. The Rights Agent shall, subject to applicable laws, and its ordinary business practices,
destroy all cancelled Rights Certificates and deliver a certificate of destruction to the Company.


 


		2.10.	Agreement of Rights Holders



 


Every holder of Rights, by
accepting the same, consents and agrees with the Company and the Rights Agent and with every other holder of Rights:


 


		(a)	to be bound by and subject to the provisions of this Agreement, as amended from time to time in accordance
with the terms hereof, in respect of all Rights held;



 


		(b)	that prior to the Separation Time, each Right will be transferable only together with, and will be transferred
by a transfer of, the associated Common Share certificate representing such Right;



 


		(c)	that after the Separation Time, the Rights Certificates will be transferable only on the Rights Register
as provided herein;



 


		(d)	that prior to due presentment of a Rights Certificate (or, prior to the Separation Time, the associated
Common Share certificate) for registration of transfer, the Company, the Rights Agent and any agent of the Company or the Rights Agent
may deem and treat the Person in whose name the Rights Certificate (or, prior to the Separation Time, the associated Common Share certificate)
is registered as the absolute owner thereof and of the Rights evidenced thereby (notwithstanding any notations of ownership or writing
on such Rights Certificate or the associated Common Share certificate made by anyone other than the Company or the Rights Agent) for all
purposes whatsoever, and neither the Company nor the Rights Agent shall be affected by any notice to the contrary;



 


		(e)	that such holder of Rights has waived his right to receive any fractional Rights or any fractional shares
or other securities upon exercise of a Right (except as provided herein);



 



    -29- 


     


    

 


		(f)	notwithstanding anything in this Agreement to the contrary, neither the Company nor the Rights Agent shall
have any liability to any holder of a Right or any other Person as a result of its inability to perform any of its obligations under this
Agreement by reason of any preliminary or permanent injunction or other order, decree or ruling issued by a court of competent jurisdiction
or by a governmental, regulatory or administrative agency or commission, or any statute, rule, regulation or executive order promulgated
or enacted by any governmental authority, prohibiting or otherwise restraining performance of such obligation; and



 


		(g)	that, subject to the provisions of Section 5.4, without the approval of any holder of Rights or Voting
Shares and upon the sole authority of the Board of Directors, this Agreement may be supplemented or amended from time to time to cure
any ambiguity or to correct or supplement any provision contained herein which may be inconsistent with the intent of this Agreement or
is otherwise defective, as provided herein.



 


		2.11.	Holder of Rights Not Deemed a Shareholder



 


No holder, as such, of any
Rights or Rights Certificate shall be entitled to vote, receive dividends or be deemed for any purpose whatsoever the holder of any Common
Share or any other share or security of the Company which may at any time be issuable on the exercise of such Rights, nor shall anything
contained herein or in any Rights Certificate be construed or deemed or confer upon the holder of any Right or Rights Certificate, as
such, any right, title, benefit or privilege of a holder of Common Shares or any other shares or securities of the Company or any right
to vote at any meeting of shareholders of the Company whether for the election of directors or otherwise or upon any matter submitted
to holders of Common Shares or any other shares of the Company at any meeting thereof, or to give or withhold consent to any action of
the Company, or to receive notice of any meeting or other action affecting any holder of Common Shares or any other shares of the Company
except as expressly provided herein, or to receive dividends, distributions or subscription rights, or otherwise, until the Right or Rights
evidenced by Rights Certificates shall have been duly exercised in accordance with the terms and provisions hereof.


 


Article 3
- ADJUSTMENTS TO THE RIGHTS IN THE EVENT OF A FLIP-IN EVENT


 


		3.1.	Flip-in Event



 


		(a)	Subject to Subsection 3.1(b) and Section 5.1, if prior to the Expiration Time a Flip-in Event
occurs, each Right shall constitute, effective at the close of business on the 10th Trading Day after the Stock Acquisition
Date, the right to purchase from the Company, upon exercise thereof in accordance with the terms hereof, that number of Common Shares
having an aggregate Market Price on the date of consummation or occurrence of such Flip-in Event equal to twice the Exercise Price for
an amount in cash equal to the Exercise Price (such right to be appropriately adjusted in a manner analogous to the applicable adjustment
provided for in Section 2.3 in the event that after such consummation or occurrence, an event of a type analogous to any of the events
described in Section 2.3 shall have occurred).



 



    -30- 


     


    

 


		(b)	Notwithstanding anything in this Agreement to the contrary, upon the occurrence of any Flip-in Event,
any Rights that are or were Beneficially Owned on or after the earlier of the Separation Time or the Stock Acquisition Date by:



 


		(i)	an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any Person acting jointly
or in concert with an Acquiring Person or any Affiliate or Associate of an Acquiring Person); or



 


		(ii)	a transferee of or other successor in title or ownership to Rights (a “transferee”),
directly or indirectly, from an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any Person acting jointly or
in concert with an Acquiring Person or any Affiliate or Associate of an Acquiring Person), where such transferee becomes a transferee
concurrently with or subsequent to the Acquiring Person becoming an Acquiring Person in a transfer that the Board of Directors has determined
is part of a plan, arrangement or scheme of an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any Person acting
jointly or in concert with an Acquiring Person or any Affiliate or Associate of an Acquiring Person), that has the purpose or effect of
avoiding Subsection 3.1(b)(i),



 


shall become null and void without any
further action, and any holder of such Rights (including transferees) shall thereafter have no right to exercise or transfer such Rights
under any provision of this Agreement and further shall thereafter not have any other rights whatsoever with respect to such Rights, whether
under any provision of this Agreement or otherwise. The holder of any Rights represented by a Rights Certificate which is submitted to
the Rights Agent upon exercise or for registration of transfer or exchange on which the holder fails to certify upon the transfer or exchange
in the place set forth in the Rights Certificate establishing that such holder is not a Person described in either Subsections 3.1(b)(i) or
(ii) above shall be deemed to be Beneficially Owned by an Acquiring Person for the purposes of this Subsection 3.1(b) and such
rights shall be null and void.


 


		(c)	From and after the Separation Time, the Company shall do all such acts and things as shall be necessary
and within its power to ensure compliance with the provisions of this Section 3.1, including without limitation, all such acts and
things as may be required to satisfy the requirements of the Canada Business Corporations Act, the Securities Act (British
Columbia) and the securities laws or comparable legislation of each of the Provinces of Canada and of the United States of America and
each of the States thereof and any other applicable law, rule or regulation in respect of the issue of Common Shares upon the exercise
of Rights in accordance with this Agreement.



 


		(d)	Any Rights Certificate that represents Rights Beneficially Owned by a Person described in either Subsections
3.1(b)(i) or (ii) or transferred to any nominee of any such Person, and any Rights Certificate issued upon transfer, exchange,
replacement or adjustment of any other Rights Certificate referred to in this sentence, shall contain the following legend:



 



    -31- 


     


    

 


“The Rights represented by this
Rights Certificate were issued to a Person who was an Acquiring Person or an Affiliate or an Associate of an Acquiring Person (as such
terms are defined in the Rights Agreement) or a Person who was acting jointly or in concert with an Acquiring Person or an Affiliate or
Associate of an Acquiring Person. This Rights Certificate and the Rights represented hereby are void or shall become void in the circumstances
specified in Subsection 3.1(b) of the Rights Agreement.”


 


provided, however, that the Rights Agent
shall not be under any responsibility to ascertain the existence of facts that would require the imposition of such legend but shall impose
such legend only if instructed to do so by the Company in writing or if a holder fails to certify upon transfer or exchange in the space
provided on the Rights Certificate that such holder is not a Person described in such legend. Notwithstanding the foregoing, the issuance
of a Rights Certificate which does not bear the legend referred to in this Subsection 3.1(d) shall not invalidate or have any effect
on the provisions of Subsection 3.1(b).


 


Article 4
- THE RIGHTS AGENT


 


		4.1.	General



 


		(a)	The Company hereby appoints the Rights Agent to act as agent for the Company and the holders of the Rights
in accordance with the terms and conditions hereof, and the Rights Agent hereby accepts such appointment. The Company may from time to
time appoint such co-Rights Agents (“Co-Rights Agents”) as it may deem necessary or desirable, subject to the approval
of the Rights Agent. In the event the Company appoints one or more Co-Rights Agents, the respective duties of the Rights Agent and Co-Rights
Agents shall be as the Company may determine, with the approval of the Rights Agent and the Co-Rights Agents. The Company agrees to pay
all reasonable fees and expenses of the Rights Agent in respect of the performance of its duties under this Agreement. The Company also
agrees to indemnify the Rights Agent, its officers, directors, and employees for, and to hold them harmless against, any loss, liability,
or expense, incurred without gross negligence, bad faith or wilful misconduct on the part of the Rights Agent, for anything done or omitted
by the Rights Agent in connection with the acceptance and administration of this Agreement, including the costs and expenses of defending
against any claim of liability, which right to indemnification will survive the termination of this Agreement or the resignation or removal
of the Rights Agent.



 


		(b)	The Rights Agent shall be protected and shall incur no liability for or in respect of any action taken,
suffered or omitted by it in connection with its administration of this Agreement in reliance upon any certificate for Common Shares,
Rights Certificate, certificate for other securities of the Company, instrument of assignment or transfer, power of attorney, endorsement,
affidavit, letter, notice, direction, consent, certificate, opinion, statement, or other paper or document believed by it in good faith
to be genuine and to be signed, executed and, where necessary, verified or acknowledged, by the proper Person or Persons.



 



    -32- 


     


    

 


		(c)	The Company shall inform the Rights Agent in a reasonably timely manner of events which may materially
affect the administration of this Agreement by the Rights Agent and, at any time upon request, shall provide to the Rights Agent an incumbency
certificate certifying the then current officers of the Company; provided that failure to inform the Rights Agent of any such events,
or any defect therein shall not affect the validity of any action taken hereunder in relation to such events.



 


		(d)	Notwithstanding any other provision of this Agreement, and whether such losses or damages are foreseeable
or unforeseeable, the Rights Agent shall not be liable under any circumstances whatsoever for any: (i) breach by any other party
of securities law or other rule of any securities regulatory authority, (ii) lost profits, or (iii) special, indirect,
incidental, consequential, exemplary, aggravated or punitive losses or damages.



 


		(e)	Notwithstanding any other provision of this Agreement, any liability of the Rights Agent shall be limited,
in the aggregate, to the amount of fees paid by the Company to the Rights Agent under this Agreement in the 12 months immediately prior
to the Rights Agent receiving the first notice of the claim.



 


		4.2.	Merger, Amalgamation or Consolidation or Change of Name of Rights Agent



 


		(a)	Any corporation into which the Rights Agent may be merged or amalgamated or with which it may be consolidated,
or any corporation resulting from any merger, amalgamation, statutory arrangement or consolidation to which the Rights Agent is a party,
or any corporation succeeding to the shareholder or stockholder services business of the Rights Agent, will be the successor to the Rights
Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided
that such corporation would be eligible for appointment as a successor Rights Agent under the provisions of Section 4.4 hereof. If,
at the time such successor Rights Agent succeeds to the agency created by this Agreement, any of the Rights Certificates have been countersigned
but not delivered, the successor Rights Agent may adopt the countersignature of the predecessor Rights Agent and deliver such Rights Certificates
so countersigned; and if, at that time, any of the Rights have not been countersigned, any successor Rights Agent may countersign such
Rights Certificates in the name of the predecessor Rights Agent or in the name of the successor Rights Agent; and in all such cases such
Rights Certificates will have the full force provided in the Rights Certificates and in this Agreement.



 



    -33- 


     


    

 


		(b)	If, at any time, the name of the Rights Agent is changed and at such time any of the Rights Certificates
have been countersigned but not delivered, the Rights Agent may adopt the countersignature under its prior name and deliver Rights Certificates
so countersigned; and if, at that time, any of the Rights Certificates have not been countersigned, the Rights Agent may countersign such
Rights Certificates either in its prior name or in its changed name; and in all such cases such Rights Certificates shall have the full
force provided in the Rights Certificates and in this Agreement.



 


		4.3.	Duties of Rights Agent



 


The Rights Agent undertakes
the duties and obligations imposed by this Agreement upon the following terms and conditions, all of which the Company and the holders
of Rights and Rights Certificates, by their acceptance thereof, shall be bound:


 


		(a)	the Rights Agent, at the expense of the Company, may consult with and retain legal counsel (who may be
legal counsel for the Company) and such other experts as it reasonably considers necessary to perform its duties hereunder, and the opinion
of such counsel or other expert will be full and complete authorization and protection to the Rights Agent as to any action taken or omitted
by it in good faith and in accordance with such opinion;



 


		(b)	whenever in the performance of its duties under this Agreement, the Rights Agent deems it necessary or
desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact
or matter (unless other evidence in respect thereof is specifically prescribed herein) is deemed to be conclusively proved and established
by a certificate signed by a Person believed by the Rights Agent to be the Chairman of the Board, President, Chief Executive Officer,
Chief Financial



 


Officer, any Vice-President or Corporate
Secretary of the Company and delivered to the Rights Agent; and such certificate will be full authorization to the Rights Agent for any
action taken or suffered in good faith by it under the provisions of this Agreement in reliance upon such certificate;


 


		(c)	notwithstanding anything to the contrary, the Rights Agent will be liable hereunder for its own gross
negligence, bad faith or wilful misconduct;



 


		(d)	the Rights Agent will not be liable for or by reason of any of the statements of fact or recitals contained
in this Agreement or in the certificates for Common Shares or the Rights Certificates (except its countersignature thereof) or be required
to verify the same, but all such statements and recitals are and will be deemed to have been made by the Company only;



 



    -34- 


     


    

 


		(e)	the Rights Agent will not have any responsibility in respect of the validity of this Agreement or the
execution and delivery hereof (except the due authorization, execution and delivery hereof by the Rights Agent) or in respect of the validity
or execution of any certificate for a Common Share or Rights Certificate (except its countersignature thereof); nor will it be responsible
for any breach by the Company of any covenant or condition contained in this Agreement or in any Rights Certificate; nor will it be responsible
for any change in the exercisability of the Rights (including the Rights becoming void pursuant to Subsection 3.1(b) hereof) or any
adjustment required under the provisions of Section 2.3 hereof or responsible for the manner, method or amount of any such adjustment
or the ascertaining of the existence of facts that would require any such adjustment (except with respect to the exercise of Rights after
receipt of the certificate contemplated by Section 2.3 describing any such adjustment); nor is it deemed by any act hereunder to
make any representation or warranty as to the authorization of any Common Shares to be issued pursuant to this Agreement or any Rights
or as to whether any Common Shares will, when issued, be duly and validly authorized, executed, issued and delivered and fully paid and
non-assessable;



 


		(f)	the Company agrees that it will perform, execute, acknowledge and deliver or cause to be performed, executed,
acknowledged and delivered all such further and other acts, instruments and assurances as may reasonably be required by the Rights Agent
for the carrying out or performing by the Rights Agent of the provisions of this Agreement;



 


		(g)	the Rights Agent is hereby authorized and directed to accept instructions in writing with respect to the
performance of its duties hereunder from any individual believed by the Rights Agent to be the Chairman of the Board, President, Chief
Executive Officer, Chief Financial Officer, any Vice-President or Corporate Secretary of the Company, and to apply to such individuals
for advice or instructions in connection with its duties, and it shall not be liable for any action taken or suffered by it in good faith
in accordance with instructions of any such individual;



 


		(h)	the Rights Agent and any shareholder or stockholder, director, officer or employee of the Rights Agent
may buy, sell or deal in Common Shares, Rights or other securities of the Company or become pecuniarily interested in any transaction
in which the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though it
were not Rights Agent under this Agreement and nothing herein shall preclude the Rights Agent from acting in any other capacity for the
Company or for any other legal entity; and



 


		(i)	the Rights Agent may execute and exercise any of the rights or powers hereby vested in it or perform any
duty hereunder either itself or by or through its attorneys or agents, and the Rights Agent will not be answerable or accountable for
any act, default, neglect or misconduct of any such attorneys or agents or for any loss to the Company resulting from any such act, default,
neglect or misconduct, provided reasonable care was exercised in the selection and continued employment thereof.



 



    -35- 


     


    

 





		4.4.	Change of Rights Agent



 


The Rights Agent may resign
and be discharged from its duties under this Agreement upon 60 days' notice (or such lesser notice as is acceptable to the Company) in
writing mailed to the Company and to each transfer agent of Common Shares by registered or certified mail. The Company may remove the
Rights Agent upon 30 days' notice in writing, mailed to the Rights Agent and to each transfer agent of the Common Shares by registered
or certified mail. If the Rights Agent should resign or be removed or otherwise become incapable of acting, the Company will appoint a
successor to the Rights Agent. If the Company fails to make such appointment within a period of 30 days after removal or 60 days after
it has been notified in writing of the resignation or incapacity by the resigning or incapacitated Rights Agent, then by prior written
notice to the Company the resigning Rights Agent or the holder of any Rights (which holder shall, with such notice, submit such holder's
Rights Certificate, if any, for inspection by the Company), may apply to a court of competent jurisdiction for the appointment of a new
Rights Agent, at the Company's expense. Any successor Rights Agent, whether appointed by the Company or by such a court, shall be a corporation
incorporated under the laws of Canada or a province thereof. After appointment, the successor Rights Agent will be vested with the same
powers, rights, duties and responsibilities as if it had been originally named as Rights Agent without further act or deed; but the predecessor
Rights Agent, upon receipt of all outstanding fees and expenses owing to it, shall deliver and transfer to the successor Rights Agent
any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the
purpose. Not later than the effective date of any such appointment, the Company will file notice thereof in writing with the predecessor
Rights Agent and each transfer agent of the Common Shares and mail a notice thereof in writing to the holders of the Rights in accordance
with Section 5.9. Failure to give any notice provided for in this Section 4.4, however, or any defect therein, shall not affect
the legality or validity of the resignation or removal of the Rights Agent or the appointment of any successor Rights Agent, as the case
may be.


 


		4.5.	Compliance with Money Laundering Legislation



 


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


 


		4.6.	Privacy Provision



 


The
parties acknowledge that federal and/or provincial legislation that addresses the protection of individual's personal information (collectively,
 “Privacy Laws”) applies to obligations and activities under this Agreement. Despite any other provision of this Agreement,
neither party will take or direcy any action that would contravene, or cause the other to contravene, applicable Privacy Laws.
The Company will, prior to transferring or causing to be transferred personal information to the Rights Agent, obtain and retain required
consents of the relevant individuals to the collection, use and disclosure of their personal information, or will have determined that
such consents either have previously been given upon which the parties can rely or are not required under the Privacy Laws. The Rights
Agent will use commercially reasonable efforts to ensure that its services hereunder comply with Privacy Laws.

Article 5
- MISCELLANEOUS


 


		5.1.	Redemption and Waiver



 


		(a)	The Board of Directors acting in good faith may, until the occurrence of a Flip-in Event, upon prior written
notice delivered to the Rights Agent, waive the application of Section 3.1 to that particular Flip-in Event provided that the particular
Flip-in Event would result from a Take-over Bid made by way of take-over bid circular sent to all holders of record of Voting Shares (which
for greater certainty shall not include the circumstances described in Subsection 5.1(h)); provided that if the Board of Directors waives
the application of Section 3.1 to a particular Flip-in Event pursuant to this Subsection 5.1(a), the Board of Directors shall be
deemed to have waived the application of Section 3.1 to any other Flip-in Event occurring by reason of any Take-over Bid which is
made by means of a take-over bid circular to all holders of record of Voting Shares prior to the expiry of any Take-over Bid (as the same
may be extended from time to time) in respect of which a waiver is, or is deemed to have been, granted under this Subsection 5.1(a).



 


		(b)	Subject to the prior consent of the holders of the Voting Shares or the Rights as set forth in Subsections
5.4(b) or (c), as the case may be, the Board of Directors of the Company acting in good faith may, at its option, at any time prior
to the provisions of Section 3.1 becoming applicable as a result of the occurrence of a Flip-in Event, elect to redeem all but not
less than all of the outstanding Rights at a redemption price of $0.00001 per Right appropriately adjusted in a manner analogous to the
applicable adjustment provided for in Section 2.3 if an event of the type analogous to any of the events described in Section 2.3
shall have occurred (such redemption price being herein referred to as the “Redemption Price”).



 


		(c)	Where, pursuant to a Permitted Bid, a Competing Permitted Bid, an Exempt Acquisition or an acquisition
for which a waiver has been granted under Subsection 5.1(a), a Person acquires more than 50% of the outstanding Voting Shares, other than
Voting Shares Beneficially Owned by such Person at the date of the Permitted Bid, the Competing Permitted Bid, the Exempt Acquisition
or an acquisition for which a waiver has been granted under Subsection 5.1(a), then the Board of Directors of the Company shall, notwithstanding
Subsection 5.1(b), immediately upon the consummation of such acquisition without further formality and without any approval under Subsections
5.4(b) or (c) be deemed to have elected to redeem the Rights at the Redemption Price.



 


		(d)	Where a Take-over Bid that is not a Permitted Bid or a Competing Permitted Bid expires, is withdrawn or
otherwise terminates after the Separation Time has occurred and prior to the occurrence of a Flip-in Event, the Board of Directors may
elect to redeem all the outstanding Rights at the Redemption Price.



 



    -37- 


     


    

 


		(e)	If the Board of Directors is deemed under Subsection 5.1(c) to have elected, or elects under either
of Subsections 5.1(b) or (d), to redeem the Rights, the right to exercise the Rights will thereupon, without further action and without
notice, terminate and the only right thereafter of the holders of Rights so redeemed shall be to receive the Redemption Price.



 


		(f)	Within 10 days after the Board of Directors is deemed under Subsection 5.1(c) to have elected, or
elects under Subsections 5.1(b) or (d), to redeem the Rights, the Company shall give notice of redemption to the holders of the then
outstanding Rights by publication of a notice in any newspaper distributed nationally in Canada or by mailing such notice to each such
holder at his last address as it appears upon the registry books of the Rights Agent or, prior to the Separation Time, on the registry
books of the transfer agent for the Voting Shares. Any notice which is mailed in the manner provided herein shall be deemed given, whether
or not the holder receives the notice. Each notice of redemption will state the method by which the payment of the Redemption Price will
be made.



 


		(g)	Upon the Rights being redeemed pursuant to Subsection 5.1(d), the directors shall be deemed to have distributed
new Rights to the holders of Voting Shares as of such date and in respect of each additional Voting Share issued thereafter, on the same
basis as Rights were first distributed hereunder and thereafter all the provisions of this Agreement shall continue to apply to such redistributed
Rights as if the Separation Time referred to in Subsection 5.1(d) had not occurred and which for all purposes of this Agreement shall
be deemed not to have occurred and the new Rights shall be outstanding and attached to the outstanding Common Shares as of and after such
date, subject to and in accordance with the provisions of this Agreement.



 


		(h)	The Board of Directors may waive the application of Section 3.1 in respect of the occurrence of any
Flip-in Event if the Board of Directors has determined within 10 Trading Days following a Stock Acquisition Date that a Person became
an Acquiring Person by inadvertence and without any intention to become, or knowledge that it would become, an Acquiring Person under
this Agreement and, in the event that such a waiver is granted by the Board of Directors, such Stock Acquisition Date shall be deemed
not to have occurred. Any such waiver pursuant to this Subsection 5.1(h) must be on the condition that such Person, within 14 days
after the foregoing determination by the Board of Directors or such earlier or later date as the Board of Directors may determine (the
 “Disposition Date”), has reduced its Beneficial Ownership of Voting Shares so that the Person is no longer an Acquiring
Person. If the Person remains an Acquiring Person at the close of business on the Disposition Date, the Disposition Date shall be deemed
to be the date of occurrence of a further Stock Acquisition Date and Section 3.1 shall apply thereto.



 


		(i)	The Company shall give prompt written notice to the Rights Agent of any waiver of the application of Section 3.1
made by the Board of Directors under this Section 5.1.



 



    -38- 


     


    

 


		(j)	Until the occurrence of a Flip-in Event as to
which the application of Section 3.1 has not been waived pursuant to this section, upon written notice to the Rights Agent, the Board
of Directors, with the prior consent of the holders of Voting Shares given in accordance with Subsection 5.4(b), may determine, if such
Flip-in Event would occur by reason of an acquisition of Voting Shares otherwise than pursuant to a Take-over Bid made by means of a take-over
bid circular to all holders of Voting Shares and otherwise than in the circumstances set forth in Subsection 5.1(h), to waive the
application of Section 3.1 to such Flip-in Event. If the Board of Directors proposes such a waiver, the Board of Directors will extend
the Separation Time to a date subsequent to and not more than 10 Business Days following the meeting of shareholders called to approve
such waiver.



 


		5.2.	Expiration



 


No Person shall have any rights
whatsoever pursuant to this Agreement or in respect of any Right after the Expiration Time, except the Rights Agent as specified in Section 4.1
of this Agreement.


 


		5.3.	Issuance of New Rights Certificates



 


Notwithstanding any of the
provisions of this Agreement or the Rights to the contrary, the Company may, at its option, issue new Rights Certificates evidencing Rights
in such form as may be approved by the Board of Directors to reflect any adjustment or change in the number or kind or class of securities
purchasable upon exercise of Rights made in accordance with the provisions of this Agreement.


 


		5.4.	Supplements and Amendments



 


		(a)	The Company may at any time, by resolution of the Board of Directors, supplement or make amendments to
this Agreement to correct any clerical or typographical error or, subject to Subsection 5.4(e), which supplements or amendments are required
to maintain the validity of this Agreement as a result of any change in any applicable legislation, rules or regulations thereunder
or policies of securities regulatory authorities or stock exchanges. The Company may, by resolution of the Board of Directors, prior to
the date of its shareholders' meeting referred to in Subsection 5.15(b), supplement or amend this Agreement without the approval of any
holders of Rights or Voting Shares (whether or not such action would adversely affect the interest of the holders of Rights or Voting
Shares generally) in order to make any changes which the Board of Directors acting in good faith may deem necessary or desirable. Notwithstanding
anything in this Section 5.4 to the contrary, no such supplement or amendment shall be made to the provisions of Article 4 except
with the written concurrence of the Rights Agent to such supplement or amendment.



 



    -39- 


     


    

 


		(b)	Subject to Subsection 5.4(a), the Company may, with the prior consent of the holders of Voting Shares
obtained as set forth below, at any time before the Separation Time, amend, vary or rescind any of the provisions of this Agreement and
the Rights (whether or not such action would materially adversely affect the interests of the holders of Rights generally). Such consent
shall be deemed to have been given if provided by the holders of Voting Shares at a Special Meeting, which Special Meeting shall be called
and held in compliance with applicable laws and regulatory requirements and the requirements in the articles of the Company. Subject to
compliance with any requirements imposed by the foregoing, consent shall be given if the proposed amendment, variation or rescission is
approved by the affirmative vote of a majority of the votes cast by Independent Shareholders present or represented in person or by proxy
at and entitled to be voted at the Special Meeting.



 


		(c)	The Company may, with the prior consent of the
holders of Rights obtained as set forth below, at any time after the Separation Time and before the Expiration Time, amend, vary or rescind
any of the provisions of this Agreement and the Rights (whether or not such action would materially adversely affect the interests of
the holders of Rights generally), provided that no such amendment, variation or deletion shall be made to the provisions of Article 4
except with the written concurrence of the Rights Agent thereto. Such consent shall be deemed to have been given if provided by the holders
of Rights at a Rights Holders' Special Meeting, which Rights Holders' Special Meeting shall be called and held in compliance with applicable
laws and regulatory requirements and, to the extent possible, with the requirements in the articles of the Company applicable to meetings
of holders of Voting Shares, applied mutatis mutandis. Subject to compliance with any requirements imposed by the foregoing, consent shall
be given if the proposed amendment, variation or rescission is approved by the affirmative vote of a majority of the votes cast by holders
of Rights (other than holders of Rights whose Rights have become null and void pursuant to Subsection 3.1(b)), represented in person or
by proxy at and entitled to be voted at the Rights Holders' Special Meeting.



 


		(d)	Any approval of the holders of Rights shall be deemed to have been given if the action requiring such
approval is authorized by the affirmative votes of the holders of Rights present or represented at and entitled to be voted at a meeting
of the holders of Rights and representing a majority of the votes cast in respect thereof. For the purposes hereof, each outstanding Right
(other than Rights which are void pursuant to the provisions hereof) shall be entitled to one vote, and the procedures for the calling,
holding and conduct of the meeting shall be those, as nearly as may be, which are provided in the Company's articles and the Canada
Business Corporations Act with respect to meetings of shareholders of the Company.



 


		(e)	Any supplements or amendments made by the Company to this Agreement pursuant to Subsection 5.4(a) which
are required to maintain the validity of this Agreement as a result of any change in any applicable legislation, rule or regulation
thereunder or policies of any securities regulatory authority or stock exchange shall:



 


		(i)	if made before the Separation Time, be submitted to the shareholders of the Company at the next meeting
of shareholders and the shareholders may, by the majority referred to in Subsection 5.4(b), confirm or reject such amendment;



 



    -40- 


     


    

 


		(ii)	if made after the Separation Time, be submitted to the holders of Rights at a meeting to be called for
on a date not later than immediately following the next meeting of shareholders of the Company called after the Separation Time and the
holders of Rights may, by resolution passed by the majority referred to in Subsection 5.4(d), confirm or reject such amendment.



 


Any such amendment shall be effective
from the date of the resolution of the Board of Directors adopting such amendment, until it is confirmed or rejected or until it ceases
to be effective (as described in the next sentence) and, where such amendment is confirmed, it continues in effect in the form so confirmed.
If such amendment is rejected by the shareholders or the holders of Rights or is not submitted to the shareholders or holders of Rights
as required, then such amendment shall cease to be effective from and after the termination of the meeting at which it was rejected or
to which it should have been but was not submitted or from and after the date of the meeting of holders of Rights that should have been
but was not held, and no subsequent resolution of the Board of Directors to amend this Agreement to substantially the same effect shall
be effective until confirmed by the shareholders or holders of Rights referred to in Subsection 5.4(b) or 5.4(c), as the case may
be.


 


		(f)	The Company shall provide the Rights Agent with notice in writing of any amendment, variation or deletion
to this Agreement as referred to in this Section 5.4 within five Business Days of effecting such amendment, variation or deletion.



 


		5.5.	Fractional Rights and Fractional Shares



 


		(a)	The Company shall not be required to issue fractions of Rights or to distribute Rights Certificates which
evidence fractional Rights. After the Separation Time, in lieu of issuing fractional Rights, the Company shall pay to the holders of record
of the Rights Certificates (provided the Rights represented by such Rights Certificates are not void pursuant to the provisions of Subsection
3.1(b), at the time such fractional Rights would otherwise be issuable), an amount in cash equal to the fraction of the Market Price of
one whole Right that the fraction of a Right that would otherwise be issuable is of one whole Right, provided that the Company shall not
be required or obligated to make any payment provided for above unless the amount payable by the Company to a certain holder exceeds $1O.



 


		(b)	The Company shall not be required to issue fractions of Common Shares upon exercise of Rights or to distribute
certificates which evidence fractional Common Shares. In lieu of issuing fractional Common Shares, the Company shall pay to the registered
holders of Rights Certificates, at the time such Rights are exercised as herein provided, an amount in cash equal to the fraction of the
Market Price of one Common Share that the fraction of a Common Share that would otherwise be issuable upon the exercise of such Right
is of one whole Common Share at the date of such exercise.



 



    -41- 


     


    

 


		(c)	The Rights Agent shall have no obligation to make any payments in lieu of issuing fractions of Rights
or Common Shares pursuant to Subsections 5.5(a) or (b), respectively, unless and until the Company shall have provided to the Rights
Agent the amount of cash to be paid in lieu of issuing such fractional Rights or Common Shares, as the case may be.



 


		5.6.	Rights of Action



 


Subject to the terms of this
Agreement, all rights of action in respect of this Agreement, other than rights of action vested solely in the Rights Agent, are vested
in the respective holders of the Rights. Any holder of Rights, without the consent of the Rights Agent or of the holder of any other Rights,
may, on such holder's own behalf and for such holder's own benefit and the benefit of other holders of Rights, enforce, and may institute
and maintain any suit, action or proceeding against the Company to enforce such holder's right to exercise such holder's Rights, or Rights
to which such holder is entitled, in the manner provided in such holder's Rights Certificate and in this Agreement. Without limiting the
foregoing or any remedies available to the holders of Rights, it is specifically acknowledged that the holders of Rights would not have
an adequate remedy at law for any breach of this Agreement and will be entitled to specific performance of the obligations under, and
injunctive relief against actual or threatened violations of the obligations of any Person subject to, this Agreement.


 


		5.7.	Regulatory Approvals



 


Any
obligation of the Company or action or event contemplated by this Agreement shall be subject to the receipt of requisite approval or consent
from any governmental or regulatory authority having jurisdiction, and without limiting the generality of the foregoing, while any securities
of the Company are listed and admitted for trading thereon, necessary approvals of the TSX and other exchanges shall be obtained,
in relation to the issuance of the Common Shares upon the exercise of Rights under Subsection 2.2(d).


 


		5.8.	Non-Canadian Holders



 


If in the opinion of the Board of Directors (who
may rely upon the advice of counsel) any action or event contemplated by this Agreement would require compliance by the Company with the
securities laws or comparable legislation of a jurisdiction outside Canada, the Board of Directors acting in good faith shall take such
actions as it may consider appropriate to ensure such compliance or avoid the application thereof. In no event shall the Company or the
Rights Agent be required to issue or deliver Rights or securities issuable on exercise of Rights to persons who are citizens, residents
or nationals of any jurisdiction other than Canada, in which such issue or delivery would be unlawful without registration of the relevant
Persons or securities for such purposes.

FORM OF RIGHTS CERTIFICATE


 


	Certificate No. _______  	 	_______Rights






 


THE RIGHTS ARE SUBJECT TO TERMINATION ON THE
TERMS SET FORTH IN THE SHAREHOLDER RIGHTS PLAN AGREEMENT. UNDER CERTAIN CIRCUMSTANCES (SPECIFIED IN SUBSECTION 3.1(b) OF THE
SHAREHOLDER RIGHTS PLAN AGREEMENT), RIGHTS BENEFICIALLY OWNED BY AN ACQUIRING PERSON OR CERTAIN RELATED PARTIES, OR TRANSFEREES OF AN
ACQUIRING PERSON OR CERTAIN RELATED PARTIES AND THEIR TRANSFEREES, MAY BECOME VOID WITHOUT FURTHER ACTION.


 


Rights Certificate


 


This certifies that _______________________________,
or registered assigns, is the registered holder of the number of Rights set forth above, each of which entitles the registered holder
thereof, subject to the terms, provisions and conditions of the Shareholder Rights Plan Agreement, originally dated as of January 22,
2016, and amended and extended as of May 15, 2019 (the “Shareholder Rights Agreement”), between ProMIS Neurosciences
Inc. (the “Company”), a company duly incorporated under the Canada Business Corporations Act, and Computershare
Trust Company of Canada, a trust company incorporated under the laws of Canada (the “Rights Agent”) (which term shall
include any successor Rights Agent under the Shareholder Rights Agreement), to purchase from the Company at any time after the Separation
Time (as such term is defined in the Shareholder Rights Agreement) and prior to the Expiration Time (as such term is defined in the Shareholder
Rights Agreement), one fully paid common share of the Company (a “Common Share”) at the Exercise Price referred to
below, upon presentation and surrender of this Rights Certificate with the Form of Election to Exercise (in the form provided hereinafter)
duly executed and submitted to the Rights Agent at its principal office in the City of Toronto, Ontario, Canada. Until adjustment thereof
in certain events as provided in the Shareholder Rights Agreement, the Exercise Price shall be an amount equal to three times the Market
Price (as such term is defined in the Rights Plan Agreement) per Common Share determined as at the Separation Time and shall be subject
to adjustment in certain events as provided in the Shareholder Rights Agreement.


 


In certain circumstances described
in the Rights Agreement, the number of Common Shares which each Right entitles the registered holder thereof to purchase shall be adjusted
as provided in the Shareholder Rights Agreement.


 


This Rights Certificate is
subject to all of the terms and provisions of the Shareholder Rights Agreement, which terms and provisions are incorporated herein by
reference and made a part hereof and to which Shareholder Rights Agreement reference is hereby made for a full description of the rights,
limitations of rights, obligations, duties and immunities thereunder of the Rights Agent, the Company and the holders of the Rights. Copies
of the Shareholder Rights Agreement are on file at the registered office of the Company.


 






     


     


    

 


This
Rights Certificate, with or without other Rights Certificates, upon surrender at any of the offices of the Rights Agent designated for
such purpose, may be exchanged for another Rights Certificate or Rights Certificates of like tenor and date evidencing an aggregate number
of Rights equal to the aggregate number of Rights evidenced by the Rights Certificate or Rights Certificates surrendered. If this Rights
Certificate shall be exercised in part, the registered holder shall be entitled to receive, upon surrender hereof, another Rights
Certificate or Rights Certificates for the number of whole Rights not exercised.


 


Subject to the provisions
of the Shareholder Rights Agreement, the Rights evidenced by this Certificate may be redeemed by the Company at a redemption price of
$0.00001 per Right, subject to adjustment in certain events, under certain circumstances at its option.


 


No fractional Common Shares
will be issued upon the exercise of any Rights evidenced hereby, but in lieu thereof a cash payment will be made, as provided in the Shareholder
Rights Agreement.


 


No holder of this Rights Certificate,
as such, shall be entitled to vote or receive dividends or be deemed for any purpose the holder of Common Shares or of any other securities
which may at any time be issuable upon the exercise hereof, nor shall anything contained in the Shareholder Rights Agreement or herein
be construed to confer upon the holder hereof, as such, any of the rights of a shareholder of the Company or any right to vote for the
election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or withhold consent to any corporate
action, or to receive notice of meetings or other actions affecting shareholders (except as provided in the Shareholder Rights Agreement),
or to receive dividends or subscription rights, or otherwise, until the Rights evidenced by this Rights Certificate shall have been exercised
as provided in the Shareholder Rights Agreement.


 


This Rights Certificate shall
not be valid or obligatory for any purpose until it shall have been countersigned by the Rights Agent.


 


WITNESS the facsimile signature of the proper
officers of the Company and its corporate seal.
