| | (vi) | after the Separation Time, except as permitted by Section 5.1 or Section 5.4 hereof, not take (or permit any Affiliate of the Corporation 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
|--- | -----------------------------------------------



| | (a) | 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 and in Article 3.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | In the event that the Corporation shall at any time after the date hereof and prior to the Expiration Time:
| | --- | -----------------------------------------------------------------------------------------------------------



| | (i) | declare or pay a dividend on the Common Shares payable in Voting Shares or Convertible Securities in respect thereof other than pursuant to any dividend reinvestment
plan;
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



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



| | (iv) | issue any Voting Shares (or Convertible Securities in respect thereof) in respect of, in lieu of or in exchange for existing Common Shares, whether in a
reclassification, amalgamation, statutory arrangement, consolidation or otherwise;
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



-18-



---

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 the exercise of Rights) shall be adjusted as follows:



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



| | 1) | the Exercise Price in effect alter 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 securities of the Corporation) (the Expansion Factor) that a holder of one Common Share immediately prior to such dividend, subdivision, change, combination or issuance would hold thereafter as a result thereof;
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
allocated among the Common Shares with respect to which the original Rights were associated (if they remain outstanding) and the securities of the Corporation issued in respect of such dividend, subdivision, change, consolidation or issuance, so
that each such Common Share (or other security of the Corporation) will have exactly one Right associated with it.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (B) | If the securities purchasable upon exercise of Rights are to be adjusted, the securities purchasable upon exercise of each Right 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 thereafter as a result thereof.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | Adjustments pursuant to Subsection 2.3(b) shall be made successively, whenever an event referred to in Subsection 2.3(b) occurs.
| | --- | --------------------------------------------------------------------------------------------------------------------------------



| | (d) | If an event occurs which would require an adjustment under both this Section 2.3 and Section 3.1 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 Section 3.1 hereof.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (e) | In the event the Corporation shall at any time after the dale hereof and prior to the Separation Time issue any Common Shares otherwise than in a transaction referred
to in Subsection 2.3(b), 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 Common Share.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (f) | In the event the Corporation shall, at any time after the date hereof and prior to the Expiration Time, fix a record date for the making of a distribution to all
holders of Common Shares of rights or warrants entitling them (for a period expiring within 45 calendar days after such record date) to subscribe for or purchase Common Shares (or Convertible Securities in respect of Common Shares) at a price per
Common Share (or, in the case of such a Convertible Security, having a conversion, exchange or exercise price per share (including the price required to be paid to purchase such Convertible Security)) less than 90% of the Market Price per Common
Share on such record date, the Exercise Price in effect after such record date will equal the Exercise Price in effect immediately prior to such record date multiplied by a fraction;
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (i) | of which the numerator shall be the number of Common Shares outstanding on such record date plus the number of Common Shares which 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 Securities so to be offered (including the price required to be paid to purchase such Convertible Securities))
would purchase at such Market Price per Common Share; and
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | of which the denominator 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 Securities so to be offered are initially convertible, exchangeable or exercisable).
| | ---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In case such subscription price is satisfied, in whole or in part, by consideration other than cash, the value of such consideration shall
be as determined in good faith by the Board of Directors. Such adjustment shall be made successively whenever such a record date is fixed. To the extent that such rights or warrants are not exercised prior to the expiration thereof, the Exercise
Price shall be readjusted in the manner contemplated above based on the number of Common Shares (or securities convertible into or exchangeable for Common Shares) actually issued on the exercise of such rights or warrants.

For purposes of this Agreement, the granting of the right to purchase Common Shares (whether from treasury or otherwise) pursuant to any
dividend or interest reinvestment plan or any share purchase plan providing for the reinvestment of dividends or interest payable on securities of the Corporation or the investment of periodic optional payments or employee benefit or similar plans
(so long as such right to purchase is in no case evidenced by the delivery of rights or warrants by the Corporation) shall not be deemed to constitute an issue of rights or warrants by the Corporation; provided, however, that in the case of any
dividend or interest reinvestment or share purchase plan, 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.



| | (g) | In the event the Corporation shall at any time after the date hereof and prior to the Expiration Time fix a record date for the making of a distribution to all holders
of Common Shares of (i) evidences of indebtedness or assets (other than a Regular Periodic Cash Dividend or a dividend paid in Common Shares, but including any dividend payable in securities other than Common Shares), (ii) rights or
warrants entitling them to subscribe for or purchase Voting Shares (or Convertible Securities in respect of Voting Shares), at a price per Voting Share (or, in the case of a Convertible Security in respect of Voting Shares, having a conversion,
exchange or exercise price per share (including the price required to be paid to purchase such Convertible Security)) less than 90% of the Market Price per Common Share on such record date (excluding rights or warrants referred to in Subsection
2.3(f)) or (iii) other securities of the Corporation, the Exercise Price in effect after such record date shall be equal to the Exercise Price in effect immediately prior to such record date less the fair market value (as determined in good
faith by the Board of Directors) of the portion of the assets, evidences of indebtedness, rights or warrants or other securities so to be distributed applicable to each of the securities purchasable upon exercise of one Right. Such adjustment shall
be made successively whenever such a record date is fixed.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (h) | Each adjustment made pursuant to Section 2.3 shall be made as of
| | --- | ----------------------------------------------------------------



| | (i) | the payment or effective date for the applicable dividend, subdivision, change, combination or issuance, in the case of an adjustment made pursuant to Subsection 2.3(b)
above; and
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | the record date for the applicable dividend or distribution, in the case of an adjustment made pursuant to Subsections 2.3(f) or 2.3(g) above, subject to readjustment
to reverse the same if such distribution shall not be made.
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | In the event the Corporation shall at any time after the date hereof and prior to the Expiration Time issue any shares (other than Common Shares), or rights or warrants
to subscribe for or purchase any such shares, or Convertible Securities in respect of any such shares, in a transaction referred to in any of subclauses 2.3(b)(i) to (iv) above, if the Board of Directors acting in good faith determines that the
adjustments contemplated by Subsections 2.3(b), 2.3(f) and 2.3(g) above in connection with such transaction will not appropriately protect the interests of the holders of Rights, the Board of Directors may from time to time, but subject to obtaining
the prior approval of the holders of the Rights obtained as set forth in Subsection 5.4, determine what other adjustments to the Exercise Price, number of Rights or securities purchasable upon exercise of Rights would be appropriate and,
notwithstanding Subsections 2.3(b), 2.3(f) and 2.3(g) above, such adjustments, rather than the adjustments contemplated by Subsections 2.3(b), 2.3(f) and 2.3(g) above, shall be made upon the Board of Directors providing written certification thereof
to the Rights Agent pursuant to Subsection 2.3(q).
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (j) | Notwithstanding anything herein to the contrary, no adjustment of the Exercise Price shall be required unless such adjustment would require an increase or decrease of
at least 1 % in such Exercise Price; provided, however, that any adjustments which by reason of this Subsection 2.3(j)) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All adjustments to
the Exercise Price made pursuant to this Section 2.3 shall be calculated to the nearest cent.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (k) | All Rights originally issued by the Corporation subsequent to any adjustment made to an 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 the Rights, all subject to further adjustment as provided herein.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (1) | Unless the Corporation shall have exercised its election, as provided in Subsection 2.3(m), upon each adjustment of an Exercise Price as a result of the calculations
made in Subsections 2.3(f) and 2.3(g), each Right outstanding immediately prior to the making of such adjustment shall thereafter evidence the right to purchase, at the adjusted Exercise Price, that number of Common Shares obtained by;
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | multiplying (A) the number of Common Shares covered by a Right immediately prior to such adjustment, by (B) the Exercise Price in effect immediately prior to
such adjustment; and
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | dividing the product so obtained by the Exercise Price in effect immediately after such adjustment.
| | ---- | ---------------------------------------------------------------------------------------------------



| | (m) | The Corporation may elect on or after the date of any adjustment of an Exercise Price to
| | --- | ----------------------------------------------------------------------------------------



-21-



---

| | adjust the number of Rights, in lieu of any adjustment in the number of Common Shares purchasable upon the exercise of a Right. Bach of the Rights outstanding after the adjustment in the number
of Rights shall be exercisable for the number of Common Shares for which a Right was exercisable immediately prior to such adjustment. Each Right held of record prior to such adjustment of the number of Rights shall become the number of Rights
obtained by dividing the relevant Exercise Price in effect immediately prior to adjustment of the relevant Exercise Price by the relevant Exercise Price in effect immediately after adjustment of the relevant Exercise Price. The Corporation shall
make a public announcement of its election to adjust the number of Rights, indicating the record date for the adjustment, and, if known at the time, the amount of the adjustment to be made. This record date may be the date on which the relevant
Exercise Price is adjusted or any day thereafter, but, if the Rights Certificates have been issued, shall be at least 10 calendar days later than the date of the public announcement. If Rights Certificates have been issued, upon each adjustment of
the number of Rights pursuant to this Subsection 2.3(m), the Corporation shall, as promptly as practicable, cause to be distributed to holders of record of Rights Certificates on such record date, Rights Certificates evidencing, subject to
Section 5.5, the additional Rights to which such holders shall be entitled as a result of such adjustment, or, at the option of the Corporation, shall cause to be distributed to such holders of record in substitution and replacement for the
Rights Certificates held by such holders prior to the date of adjustment, and upon surrender thereof, if required by the Corporation, new Rights Certificates evidencing all the Rights to which such holders shall be entitled after such adjustment,
Rights Certificates so to be distributed shall be issued, executed and countersigned in the manner provided for herein and may bear, at the option of the Corporation, the relevant adjusted Exercise Price and shall be registered in the names of
holders of record of Rights Certificates on the record date specified in the public announcement.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



| | (o) | Notwithstanding anything in this Section 2.3 to the contrary, the Corporation shall be entitled to make such adjustments in the Exercise Price, in addition to
those adjustments expressly required by this Section 2.3, as and to the extent that in its good faith judgment the Board of Directors shall determine to be advisable in order that any (i) subdivision or consolidation of the Common Shares,
(ii) issuance wholly for cash of any Common Shares at less than the applicable Market Price, (iii) issuance wholly for cash of any Common Shares or securities that by their terms are exchangeable for or convertible into or give a right to
acquire Common Shares, (iv) stock dividends, or (v) issuance of rights, options or warrants referred to in this Section 2.3, hereafter made by the Corporation to holders of its Common Shares, shall not be taxable to such shareholders.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (p) | Irrespective of any adjustment or change in the securities purchasable upon exercise of the Rights, the Rights Certificates theretofore and thereafter issued may
continue to represent the securities so purchasable which were represented in the initial Rights Certificates issued hereunder.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



-22-



---

| | (q) | Whenever an adjustment to the Exercise Price is made pursuant to this Section 2.3, the Corporation shall
| | --- | --------------------------------------------------------------------------------------------------------



| | (i) | promptly prepare a certificate setting forth such adjustment and a brief statement of the facts accounting for such adjustment; and
| | --- | -----------------------------------------------------------------------------------------------------------------------------------



| | (ii) | promptly file with the Rights Agent and with each transfer agent for the Common Shares a copy of such certificate and mail a brief summary thereof to each holder of
Rights who requests a copy.
| | ---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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 any such adjustment or change.



|2.4 | Date on Which Exercise is Effective
|--- | -----------------------------------

Each Person in whose name any certificate for Common Shares is issued upon the exercise of Rights shall for all purposes be deemed to have
become the holder of record of the Common Shares represented thereby on, and such certificate shall be dated, the date upon which the Rights Certificate evidencing such Rights was duly surrendered (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 Person hereunder) was made; provided, however, that if the dale of such surrender and payment is
a date upon which the Common Share transfer books of the Corporation 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 Business Day on which the Common Share
transfer books of the Corporation are open.



|2.5 | Execution, Authentication, Delivery and Dating of Rights Certificates
|--- | ---------------------------------------------------------------------



| | (a) | The Rights Certificates shall be executed on behalf of the Corporation by its President, Chief Executive Officer, Chief Financial Officer, Secretary or any Vice
President. 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 Corporation shall
bind the Corporation, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the countersignature and delivery of such Rights Certificates.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Corporation to the Rights Agent for countersignature and a statement describing the Rights, and the Rights Agent shall countersign (manually or by facsimile signature) and deliver such Rights Certificates and statement to the holders of the Rights
pursuant to Section 2.2 hereof. No Rights Certificate shall be valid for any purpose until countersigned by the Rights Agent as aforesaid.

|2.6 | Registration, Transfer and Exchange
|--- | -----------------------------------



| | (a) | After the Separation Time, the Corporation shall cause to be kept a register (the Rights Register) in which, subject to such reasonable regulations
as it may prescribe, the Corporation will provide for the registration and transfer of Rights. The Rights Agent is hereby appointed Rights Registrar for the purpose of maintaining the Rights Register for the Corporation 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.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | 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 Subsections 2.6(d) and 3.1(b) below, the Corporation will execute, and the Rights Agent will countersign, deliver and register, 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.

| | (d) | Every Rights Certificate surrendered for registration of transfer or exchange shall be duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Corporation 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 Corporation 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 fees and expenses of the Rights Agent) in
connection therewith,
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.7 | Mutilated, Lost, Stolen and Destroyed Rights Certificates
|--- | ---------------------------------------------------------



| | (a) | if any mutilated Rights Certificate is surrendered to the Rights Agent prior to the Expiration Time, the Corporation shall execute and the Rights Agent shall

loss or theft of any Rights Certificate; and (ii) such security or 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 Corporation or the Rights Agent that
such Rights Certificate has been acquired by a bona fide purchaser, the Corporation shall execute and, upon the Corporation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 Rights Certificate so destroyed, lost or stolen.

| | (d) | Every new Rights Certificate issued pursuant to this Section 2.7 in lieu of any destroyed, lost or stolen Rights Certificate shall evidence a contractual

Rights duly issued hereunder.

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. 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, the associated Common Shares).



|2.9 | Delivery and Cancellation of Certificates
|--- | -----------------------------------------

All Rights Certificates surrendered upon exercise or for redemption, for 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 Corporation may at any time deliver to the Rights Agent for cancellation any Rights Certificates previously
countersigned and delivered hereunder which the Corporation 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

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.

ADJUSTMENTS TO THE RIGHTS



|3.1 | Flip-in Event
|--- | -------------



| | (a) | Subject to subsections 3. 1 (b) and 5.1 (b), 5.1(c) and 5.1(d) hereof, in the event that prior to the Expiration Time a Flip-in Event occurs, the Corporation shall
take such action as shall be necessary to ensure and provide, within 10 Business Days thereafter or such longer period as may he required to satisfy the requirements of applicable securities acts or comparable legislation so that, except as provided
below, each Right shall thereafter constitute the right to purchase from the Corporation, upon exercise thereof in accordance with the terms hereof, that number of Common Shares of the Corporation as have 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 date of consummation or occurrence, an event of a type analogous to any of the events described in Section 2.3 shall have occurred with respect to such Common Shares)
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (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 and the Stock Acquisition Date, or which may thereafter be Beneficially Owned, by:

|4.4 | Change of Rights Agent
|--- | ----------------------

The Rights Agent
may resign and be discharged from its duties under this Agreement by giving 60 days prior written notice (or such lesser notice as is acceptable to the. Corporation) to the Corporation, to each transfer agent of Common Shares and to the
holders of the Rights, all in accordance with Section 5.9 and at the expense of the Corporation. The Corporation may remove the Rights Agent by giving 30 days prior written notice to the Rights Agent, to each transfer agent of the Common
Shares and to the holders of the Rights in accordance with Section 5.9. If the Rights Agent should resign or be removed or otherwise become incapable of acting, the Corporation will appoint a successor to the Rights Agent. If the Corporation
fails to make such appointment within a period of 30 days after such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent or by the holder of any Rights (which holder
shall, with such notice, submit such holders Rights Certificate for inspection of the Corporation), then the holder of any Rights or the Rights Agent may apply to any court of competent jurisdiction for the appointment of a new Rights Agent at
the Corporations expense. Any successor Rights Agent, whether appointed by the Corporation or by such a court, must be a corporation incorporated under the laws of Canada or a province thereof and authorized to carry on the business of a trust
company in the Province of Ontario. 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 any outstanding fees and expenses then owing, 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 Corporation 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 the successor Rights Agent, as the case may be

thereto, and (ii) neither the exercise by the Board of Directors of any power or discretion conferred on it hereunder nor the making by the Board of Directors of any determination or the granting of any waiver it is permitted to make or give

Right. The Rights Agent shall have no obligation to make payments in lieu of fractional Rights unless the Corporation shall have provided the Rights Agent with the necessary funds to pay in full all amounts payable in accordance with subsection
2.2(e) hereof.

| | (b) | The Corporation shall not be required to issue fractional Common Shares upon exercise of the Rights or to distribute certificates that evidence fractional Common
Shares. In lieu of issuing fractional Common Shares, the Corporation shall pay to the registered holder of Rights Certificates at the time such Rights are exercised as herein provided, an amount in cash equal to the same fraction of the Market Price
of one Common Share at the date of such exercise. The Rights Agent shall have no obligation to make payments in lieu of fractional Common Shares unless the Corporation shall have provided the Rights Agent with the necessary funds to pay in full all
amounts payable in accordance with subsection 2.2(e) hereof.
