***Background***

On November 21, 2025, the Board of Directors (the "Board") of NioCorp Developments Ltd., a corporation incorporated under the laws of the Province of British Columbia (the "Company"), approved the Company's limited-duration shareholder rights plan (the "Rights Plan") as set forth in the Shareholder Rights Plan Agreement, dated as of November 21, 2025 (the "Rights Plan Agreement"), by and between the Company and Computershare Investor Services Inc., as rights agent (or any successor rights agent) (the "Rights Agent"). The Board adopted the Rights Plan to help ensure that all shareholders of the Company are treated equally and fairly in the event of any unsolicited take-over bid or other attempt to acquire control of the Company (including by way of a "creeping take-over bid"). In respect of such transactions, the Rights Plan is intended to, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;· encourage potential bidders to treat the Company's shareholders fairly and equally and preserve
control premiums and value for shareholders; and

&nbsp;&nbsp;&nbsp;&nbsp;· provide the Board and shareholders adequate time to appropriately respond on an informed basis.

The Rights Plan was not adopted in response to any specific take-over bid or other proposal to acquire control of the Company, and the Company is not aware of any such pending or contemplated take-over bid or other proposal.

 ****

***Summary of the Rights Plan***

*Effective Date and Term*

 

The Rights Plan became effective on November 21, 2025 (the "Effective Date"), after approval by the Board on November 21, 2025. The Rights Plan has a term of six months and will expire on May 21, 2026, or earlier upon the redemption of the Rights (as defined below) or, provided that a Flip-in Event (as defined below) has not occurred, at the discretion of the Board (the "Expiration Time").

 

*Issue of Rights*

 

At the close of business on December 4, 2025 (the "Record Time"), one right (a "Right") will be issued and attached to each common share of the Company ("Common Share") outstanding as at the Record Time. Thereafter, one Right will attach to each Common Share issued after the Record Time and prior to the earlier of the Separation Time (as defined below) and the Expiration Time.

 

*Rights Exercise Privilege*

 

The Rights are not exercisable initially. The Rights generally separate from the Common Shares and become exercisable (A) ten trading days after the earlier of (i) the first date of public announcement or disclosure by the Company or an Acquiring Person (defined below) of facts indicating that a person has become an Acquiring Person (such date being the "Stock Acquisition Date"), (ii) the date of the commencement of or first public announcement or disclosure of the current intention of any person (other than the Company or any of its subsidiaries) to commence a take-over bid which would result in such person becoming the Beneficial Owner (as defined in the Rights Plan Agreement) of 20% or more of the outstanding Common Shares and any other shares in the capital of the Company entitled to vote generally in the election of directors (collectively, "Voting Shares"), other than pursuant to a Permitted Bid or a Competing Permitted Bid (each as defined below), and (iii) the date on which a Permitted Bid or a Competing Permitted Bid ceases to qualify as such, or (B) such later time as may be determined by the Board (in any such case, the "Separation Time"). From and after the Separation Time and prior to the Expiration Time, each Right will entitle the holder thereof to purchase one Common Share for the Exercise Price (as defined in the Rights Plan Agreement) as at the business day immediately preceding the Separation Time, subject to certain adjustments, including in connection with a Flip-in Event, as described below. The transaction or event in or pursuant to which any person (an "Acquiring Person") becomes the Beneficial Owner of 20% of the outstanding Voting Shares, other than by way of a Permitted Bid or a transaction otherwise permitted by the Rights Plan, is referred to as a "Flip-in Event."

Any Rights held by an Acquiring Person (or any Affiliate or Associate (as each such term is defined in the Rights Plan Agreement) of an Acquiring Person or any other person acting jointly or in concert with an Acquiring Person or any Affiliate or Associate of such other person) will become null and void upon the occurrence of a Flip-in Event. Ten trading days after the Stock Acquisition Date, each Right (excluding Rights held by an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any other person acting jointly or in concert with an Acquiring Person or any Affiliate or Associate of such other person or certain transferees) which have become void) will permit the purchase of that number of Common Shares having an aggregate Market Price (as defined in the Rights Plan Agreement) 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. The "Exercise Price" is defined, for the period from and after the Separation Time, as an amount equal to three (3) times the Market Price per Common Share determined as at the Separation Time. For instance, if the Market Price at the Separation Time is $10 per share, the Exercise Price would be $30 and each Right would entitle the holder to acquire Common Shares having an aggregate Market Price on the date of consummation or occurrence of a Flip-in Event of $60 (i.e., twice the Exercise Price [2 x $30]) in exchange for cash consideration equal to the Exercise Price. In effect, each shareholder (other than an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any other person acting jointly or in concert with an Acquiring Person or any Affiliate or Associate of such other person or certain transferees)) will have the right, upon the occurrence of a Flip-in Event, to acquire six (6) Common Shares at a price equal to $30 (or 50% of the Market Price, as determined for the purposes of the Rights Plan), assuming the Market Price per Common Share on the date of consummation or occurrence of a Flip-in Event is $10.

The Rights Plan Agreement provides for certain adjustments to the Exercise Price and the number of Rights outstanding upon the occurrence of certain events, including, without limitation, the declaration or payment of a stock dividend on the Common Shares, the subdivision or consolidation of the outstanding Common Shares, and the fixing of a record date for distributions to all holders of Common Shares.

 

*Trading of Rights*

 

Until the Separation Time, the Rights will be evidenced by the certificates or book entries representing the associated Common Shares and will be transferable only together with the associated Common Shares. Promptly following the Separation Time, the Company will determine whether it wishes to issue separate certificates evidencing the Rights ("Rights Certificates") or whether it will maintain the Rights in book entry form. If the Company decides to maintain Rights in book entry form, it will put in place such alternative procedures as are determined necessary in consultation with the Rights Agent for the Rights to be maintained in book entry form. In the event that the Company determines to issue Rights Certificates, then promptly following the Separation Time, Rights Certificates will be sent to holders of record of Common Shares (other than an Acquiring Person or certain transferees) as of the Separation Time. Rights Certificates will also be issued for Rights in respect of Common Shares issued after the Separation Time and before the Expiration Time, to each holder (other than an Acquiring Person or certain transferees) converting securities that are exchangeable for Common Shares after the Separation Time. Rights will trade separately from the Common Shares after the Separation Time.

 

*Permitted Lock-up Agreements*

 

A bidder may enter into lock-up agreements (a "Permitted Lock-Up Agreement") with shareholders whereby such shareholders agree to deposit or tender their Voting Shares and/or Convertible Securities (as defined in the Rights Plan Agreement) to a take-over bid (the "Lock-Up Bid") without a Flip-in Event occurring, because such Voting Shares and/or Convertible Securities will not be deemed to be beneficially owned by the bidder for purposes of the Rights Plan Agreement.

Such Permitted Lock-Up Agreement must be publicly disclosed and permit the shareholder to terminate its obligation to deposit or tender Voting Shares and/or Convertible Securities or not to withdraw its securities from the Permitted Lock-Up Agreement in order to deposit or tender the Voting Shares and/or Convertible Shares to another take-over bid or support another transaction that in either case (A)(i) will provide a greater price or value to the shareholder than the Lock-Up Bid or (ii) contains an offer price or value for each Voting Share or Convertible Security that exceeds by as much as or more than a specified amount, which specified amount may not be greater than 7% of the price or value to the shareholder of the Lock-Up Bid, and (B) if the number of Voting Shares or Convertible Securities to be purchased under the Lock-Up Bid is less than 100% of the Voting Shares or Convertible Securities held by Independent Shareholders (as defined below), the number of Voting Shares or Convertible Securities to be purchased under such other take-over bid or transaction at a price or value that is not less than the Lock-Up Bid (i) will be greater than the number of Voting Shares or Convertible Securities offered to be purchased under the Lock-Up Bid or (ii) exceeds the number of Voting Shares or Convertible Securities offered to be purchased under the Lock-Up Bid by as much or more than a specified amount, which specified amount may not be greater than 7% of the number of Voting Shares or Convertible Securities offered to be purchased under the Lock-Up Bid.

In addition, such Permitted Lock-Up Agreement must provide that no "break-up" fees, "top-up" fees, penalties, expenses or other amounts that exceed, in the aggregate, the greater of (i) the cash equivalent of 2.5% of the price or value of the consideration payable under the Lock-Up Bid to such shareholder and (ii) 50% of the increase in the consideration received under another take-over bid or transaction shall be payable by the shareholder if the shareholder fails to deposit or tender its securities to the Lock-Up Bid, withdraws Voting Shares and/or Convertible Securities previously deposited or tendered thereto or supports another transaction.

 

*Permitted Bid Requirements*

 

A "Permitted Bid" is a take-over bid, made by an Offeror (as defined below) by way of take-over bid circular, which also complies with the following additional provisions:

&nbsp;&nbsp;&nbsp;&nbsp;· the take-over bid is made to all holders of Voting Shares on the books of the Company, other than the
Offeror;

&nbsp;&nbsp;&nbsp;&nbsp;· the take-over bid contains an irrevocable and unqualified provision that no Voting Shares and/or Convertible Securities will be taken
up or paid for pursuant to the take-over bid unless more than 50% of the Voting Shares held by Independent Shareholders (i) shall have
been deposited or tendered pursuant to the take-over bid and not withdrawn and (ii) have previously been or are taken up at the same time;

&nbsp;&nbsp;&nbsp;&nbsp;· the take-over bid contains, and the take-up and payment for securities tendered or deposited is subject to, an irrevocable and unqualified
provision that no Voting Shares and/or Convertible Securities will be taken up or paid for pursuant to the take-over bid prior to the
close of business on the date that is not less than (i) 105 days following the date of the take-over bid or (ii) the last day of such
shorter minimum deposit period for which a take-over bid (that is not exempt from any requirements of Division 5 (Bid Mechanics) of NI
62-104) must remain open for deposits of securities, in the applicable circumstances at such time, pursuant to section 2.28.2 or section
2.28.3 of NI 62-104;

&nbsp;&nbsp;&nbsp;&nbsp;· the take-over bid contains an irrevocable and unqualified provision that unless the take-over bid is withdrawn, Voting Shares and/or
Convertible Securities may be deposited or tendered pursuant to such take-over bid at any time during the period of time between the date
of the take-over bid and the date on which Voting Shares may be taken up and paid for and that any Voting Shares deposited pursuant to
the take-over bid may be withdrawn until taken up and paid for; and

&nbsp;&nbsp;&nbsp;&nbsp;· the take-over bid contains an irrevocable and unqualified provision that if, on the date on which Voting Shares may be taken up and
paid for under the take-over bid, more than 50% of the Voting Shares held by Independent Shareholders have been deposited or tendered
pursuant to the take-over bid and not withdrawn, the Offeror will make a public announcement of that fact and the take-over bid will remain
open for deposits and tenders of Voting Shares and/or Convertible Securities for not less than ten days from the date of such public announcement.

For purposes of the Rights Plan Agreement, (i) should a take-over bid which qualified as a Permitted Bid cease to be a Permitted Bid because it ceases to meet any or all of the requirements mentioned above prior to the time it expires (after giving effect to any extension) or is withdrawn, any acquisition of Voting Shares and/or Convertible Securities made pursuant to such take-over bid shall not be a Permitted Bid Acquisition (as defined in the Rights Plan Agreement) and (ii) the term "Permitted Bid" shall include a Competing Permitted Bid.

"Independent Shareholders" is defined in the Rights Plan Agreement as holders of outstanding Voting Shares, other than any Acquiring Person, any person that is making or has announced a current intention to make a take-over bid but only so long as the take-over bid so announced or made has not been withdrawn or terminated or has not expired (an "Offeror") (other than a person who by virtue of the exception for investment advisors described below is not deemed to beneficially own the Voting Shares held by such person for purposes of the Rights Plan Agreement), Affiliates or Associates of an Acquiring Person or Offeror, any person acting jointly or in concert with such Acquiring Person or Offeror (which excludes customary agreements with and between underwriters and/or banking group members and/or selling group members with respect to a distribution of securities of the Company, pledges of securities in the ordinary course of business and Permitted Lock-Up Agreements) and any employee benefit, deferred profit sharing plan, stock participation plan and any other similar plan or trust for the benefit of employees of the Company or a subsidiary, unless the beneficiaries of the plan or trust direct the manner in which the Voting Shares are to be voted or withheld from voting or direct whether the Voting Shares are to be deposited or tendered to a take-over bid.

The Rights Plan allows for a Competing Permitted Bid to be made while a Permitted Bid is in existence. A "Competing Permitted Bid" is a take-over bid that:

&nbsp;&nbsp;&nbsp;&nbsp;· is made after a Permitted Bid or another Competing Permitted Bid has been made and prior to the expiry, termination or withdrawal
of such Permitted Bid or Competing Permitted Bid;

&nbsp;&nbsp;&nbsp;&nbsp;· complies with all of the provisions of a Permitted Bid other than the condition set forth in the third bullet of the definition of
a Permitted Bid above; and

&nbsp;&nbsp;&nbsp;&nbsp;· contains, and the take-up and payment for securities tendered or deposited is subject to, an irrevocable and unqualified provision
that no Voting Shares will be taken up or paid for pursuant to the take-over bid prior to the close of business on the date that is no
earlier than the date on which Voting Shares may be taken up under any Permitted Bid (determined as of the date of making the take-over
bid, assuming no amendment or variation to the terms and satisfaction of all conditions to the completion of the Permitted Bid) that preceded
the Competing Permitted Bid;

provided that, should a Competing Permitted Bid cease to be a Competing Permitted Bid because it ceases to meet any or all of the requirements mentioned above prior to the time it expires (after giving effect to any extension) or is withdrawn, then any acquisition of Voting Shares made pursuant to such Competing Permitted Bid, including any acquisition of Voting Shares made prior to such time, shall not be a Permitted Bid Acquisition.

 

*Waiver*

 

The Board, acting in good faith, may, until the occurrence of a Flip-in Event, waive the application of the Rights Plan to a particular Flip-in Event where it would occur by reason of a take-over bid which is made by a take-over bid circular sent to all holders of Voting Shares.

Where the Board exercises such waiver power for a particular Flip-in Event, the Board shall be deemed to have exercised such waiver power to any other Flip-in Events subsequently occurring by reason of a take-over bid which is made by means of a take-over bid circular to all holders of Voting Shares prior to the expiry of any other bid for which the Rights Plan is, or is deemed to have been, waived.

The Board may, in respect of any Flip-in Event, waive the application of the Rights Plan to a particular Flip-in Event where the Board has determined within ten trading days following a Stock Acquisition Date that the Acquiring Person became an Acquiring Person by inadvertence and without any intent or knowledge that it would become an Acquiring Person and such person has reduced its beneficial ownership within fourteen days after the foregoing determination by the Board such that it is no longer an Acquiring Person.

The Board, acting in good faith, may, with the approval of a majority of votes cast by the Independent Shareholders voting in person or by proxy at a meeting duly called for that purpose, determine, at any time prior to the occurrence of a Flip-in Event, to waive the application of the Rights Plan for any Flip-in Event.

*Redemption*

 

The Board, with prior approval of the holders of Voting Shares or the holders of Rights, at any time prior to the occurrence of a Flip-in Event, may redeem all of the then outstanding Rights at a price of $0.00001 each, subject to adjustment.

 

*Amendment*

 

The Board may amend the Rights Plan Agreement with the prior approval of the holders of Voting Shares (or holders of Rights if the Separation Time has occurred).

The Board, without such approval, may make amendments to the Rights Plan Agreement to correct any clerical or typographical error, which are required to maintain the validity of the Rights Plan Agreement as a result of any change in any applicable legislation or regulations or rules thereunder, or to cure any ambiguity, to correct or supplement any provision therein which may be defective or inconsistent with any other provision therein, or to make any other provisions with respect to matters or questions arising thereunder, provided that such action shall not adversely affect the interests of the holders of Voting Shares or Rights in any material respect.

*Exception for Investment Advisors*

 

Investment managers (for client accounts), trust companies (acting in their capacity as trustees or administrators or in a similar capacity), statutory bodies managing investment funds (for employee benefit plans, pension plans, insurance plans or various public bodies) and registered pension funds or plans and their administrators or trustees who become the Beneficial Owner of 20% or more of the outstanding Voting Shares are exempted from triggering a Flip-in Event, provided that they are not making and have not announced an intention to make, a take-over bid, alone or by acting jointly or in concert with any other person.

The foregoing descriptions of the Rights, the Rights Plan and the Rights Plan Agreement are qualified in their entirety by reference to the full text of the Rights Plan Agreement, a copy of which is filed as Exhibit 4.1 to this Current Report on Form 8-K and is incorporated by reference herein.

**SHAREHOLDER RIGHTS PLAN AGREEMENT**

THIS SHAREHOLDER RIGHTS PLAN AGREEMENT is made as of November 21, 2025 between NioCorp Developments Ltd. (the "**Corporation**"), a corporation incorporated under the laws of the Province of British Columbia, and Computershare Investor Services Inc., a company existing under the laws of Canada (the "**Rights Agent**").

**WHEREAS** the Board of Directors, in the exercise of its fiduciary duties to the Corporation, has determined that it is in the best interests of the Corporation to adopt a shareholder protection rights plan (the "**Rights Plan**") to prevent, to the extent possible, a creeping takeover of the Corporation, to ensure that any offer to acquires shares of the Corporation is made to all shareholders and cannot be completed unless shareholders holding at least 50% of the outstanding shares (other than the offeror and related parties) are deposited or tendered in acceptance of the offer, and to ensure, to the extent possible, the fair treatment of all shareholders in connection with any take-over bid for the securities of the Corporation, and to ensure that the Board of Directors is provided with sufficient time to evaluate unsolicited take-over bids and to explore and develop alternatives to maximize shareholder value;

**AND WHEREAS** in order to implement the adoption of a shareholder rights plan as established by this Agreement (as hereinafter defined), the Board of Directors has:

the Record Time and one Right shall be issued in respect of each Voting Share issued after the Record Time and prior to the earlier of
the Separation Time and the Expiration Time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Certificates representing Voting Shares which are issued after the Record Time but prior to the earlier
of the Separation Time and the Expiration Time, shall also evidence one Right for each Voting Share represented thereby until the earlier
of the Separation Time or the Expiration Time and shall have impressed on, printed on, written on or otherwise affixed to them the following
legend:

*Until the earlier of the Separation Time or the Expiration Time (as both terms are defined in the Shareholder Rights Agreement referred to below), this certificate also evidences and entitles the holder hereof to certain Rights as set forth in a Shareholder Rights Plan Agreement dated as of November 21, 2025, as may be amended or supplemented from time to time (the "Shareholder Rights Agreement"), between NioCorp Developments Ltd. (the "Corporation") and Computershare Investor Services Inc., as Rights Agent, the terms of which are incorporated herein by reference, and a copy of which is on file at the principal executive offices of the Corporation, is available for viewing at www.sedarplus.ca and www.edgar.com and is available to the holder upon demand without charge. Under certain circumstances set out in the Shareholder Rights Agreement, the Rights may be amended or redeemed, may expire or may become void (if, in certain cases they are "Beneficially Owned" by an "Acquiring Person" as such terms are defined in the Shareholder Rights Agreement, whether currently held by or on behalf of such Person or a subsequent holder) or may be evidenced by separate certificates and no longer evidenced by this certificate. The Corporation will mail or arrange for the mailing of a copy of the Shareholder Rights Agreement to the holder of this certificate without charge as soon as practicable after the receipt of a written request therefor.*

Notwithstanding the foregoing, until the earlier of the Separation Time and the Expiration Time, certificates representing Voting Shares shall also evidence one Right for each Voting Share evidenced thereby, notwithstanding the absence of the foregoing legend.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Any Voting Shares issued and registered in Book Entry Form prior to the earlier of the Separation Time
and the Expiration Time shall evidence, in addition to the Voting Shares, one Right for each Voting Share represented thereby and the
registration record of such Voting Shares shall include the foregoing legend, adapted accordingly as the Rights Agent may reasonably require.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Subject to 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, or its Canadian Dollar Equivalent,
as at the Business Day immediately preceding the Separation Time (which 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 Corporation or any of its Subsidiaries
shall be null and void.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Until the Separation Time:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) for administrative purposes, each Right will be evidenced by the certificate for the associated Voting
Share registered in the name of the holder thereof (which certificate shall also be deemed to represent a Rights Certificate) or by Book
Entry Form registration for the associated Voting Share and will be transferable only together with, and will be transferred by a transfer
of, such associated Voting Share.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 Voting Shares. Promptly following the Separation Time, the Corporation
will determine whether it wishes to issue Rights Certificates or whether it will maintain the Rights in Book Entry Form. In the event
that the Corporation determines to maintain Rights in Book Entry Form, it will put in place such alternative procedures as are determined
necessary in consultation with the Rights Agent for the Rights to be maintained in Book Entry Form (the "**Book Entry Rights Exercise Procedures** "), it being hereby acknowledged that such procedures shall, to the greatest extent possible, replicate in all substantive
respects the procedures set out in this Agreement with respect to the exercise of the Rights Certificates and that the procedures set
out in this Agreement shall be modified only to the extent necessary, as reasonably determined by the Rights Agent, to permit the Corporation
to maintain the Rights in Book Entry Form. In such event, the Book Entry Rights Exercise Procedures shall be deemed to replace the procedures
set out in this Agreement with respect to the exercise of Rights and all provisions of this Agreement referring to the Rights Certificates
shall be applicable to Rights registered in Book Entry Form in like manner as the Rights in certificated form.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) In the event that the Corporation determines to issue Rights Certificates, then promptly following the
Separation Time, the Corporation will prepare or cause to be prepared and the Rights Agent will, as soon as reasonably practicable, mail
to each holder of record of Voting Shares as of the Separation Time and, in respect of each Convertible Security converted into Voting
Shares after the Separation Time and prior to the Expiration Time, promptly after such conversion, the Corporation will prepare or cause
to be prepared and the Rights Agent will mail to the holder so converting (other than in either case a person indicated by the Corporation
in writing to be an Acquiring Person and any Transferee whose rights are or become null and void pursuant to Section 3.1(b) and, in respect
of any Rights Beneficially Owned by such Acquiring Person or Transferee which are not held of record by such Acquiring Person or Transferee,
the holder of record of such Rights as indicated by the Corporation in writing (a "**Nominee** ")), at such holder's
address as shown by the records of the Corporation (the Corporation hereby agreeing to furnish copies of such records to the Rights Agent
for this purpose):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(x) a Rights Certificate appropriately completed, representing the number of Rights held by such holder at
the Separation Time or at the time of conversion, as applicable, and having such marks of identification or designation and such legends,
summaries or endorsements printed thereon as the Corporation 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 judicial or administrative order made pursuant thereto
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 usage; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(y) a disclosure statement prepared by the Corporation describing the Rights,

provided that a Nominee shall be sent the materials provided for in (x) and (y) only in respect of all Voting Shares held of record by it which are not Beneficially Owned by an Acquiring Person. In order for the Corporation to determine whether any Person is holding Voting Shares which are Beneficially Owned by another Person, the Corporation may require such first Person to furnish such information and documentation as the Corporation deems necessary.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) In the event that the Corporation determines to issue Rights Certificates, 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, at its principal office in
Vancouver, British Columbia or Toronto, Canada or any other office of the Rights Agent in cities designated from time to time for that
purpose by the Corporation with the approval of the Rights Agent:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the Rights Certificate evidencing such Rights;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 such holder's executors or administrators or other personal
representatives or such holder's or their legal attorney duly appointed by an instrument in writing in form and executed in a manner
satisfactory to the Rights Agent; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) payment by certified cheque, banker's draft, money order or wire transfer payable to the order of the Rights Agent, 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) In the event that the Corporation determines to issue Rights Certificates, then upon receipt of a Rights
Certificate, together with a completed Election to Exercise executed in accordance with Subsection 2.2(e)(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(e)(iii), the Rights Agent
(unless otherwise instructed by the Corporation in the event that the Corporation is of the opinion that the Rights cannot be exercised
in accordance with this Agreement) will thereupon as soon as practicable:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) when appropriate, requisition from the Corporation the amount of cash, if any, to be paid in lieu of issuing fractional Common
Shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) after receipt of the certificates referred to in Subsection 2.2(f)(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;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) remit to the Corporation all payments received on the exercise of Rights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) The Corporation covenants and agrees that it will:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) cause to be reserved and kept available out of its 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) take all such action as may be necessary and within its power to ensure that all Common Shares delivered
upon the 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) take all such action as may be necessary and within its power to comply with the requirements of the BCBCA,
the Securities Act and the other applicable securities laws or comparable legislation of each of the provinces and territories of Canada,
the 1933 Securities Act, the 1934 Exchange Act, and any other applicable law, rule or regulation, in connection with the issuance and
delivery of the Rights, the Rights Certificates and the issuance of any Common Shares upon exercise of the Rights;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) pay when due and payable, if applicable, any and all federal, provincial, state and municipal transfer
taxes and charges (not including any income or capital taxes of the holder or exercising holder or any liability of the Corporation 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 Corporation 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 issued upon the exercise of Rights in a name other than that of the holder of the Rights being transferred
or exercised; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) after the Separation Time, except as permitted by Sections 5.1 and 5.4, 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 and in Article 3.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) In the event the Corporation shall at any time after the Effective Date and prior to the Expiration Time:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) declare or pay a dividend on Common Shares payable in Common Shares or Convertible Securities in respect thereof other than pursuant
to any Dividend Reinvestment Plan;

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) issue
any Common Shares (or Convertible Securities in respect thereof) in respect of, in lieu of or in exchange for existing Common Shares
except as otherwise provided in this Section 2.3,

then 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.

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

x 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) (the "**Expansion Factor**") that a holder of one Common Share immediately prior to such dividend, subdivision, change, consolidation or issuance would hold thereafter as a result thereof; and

---

| | |
|:---|:---|
| y | 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 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 of such dividend, subdivision, change, consolidation or issuance.

Adjustments made pursuant to this Section 2.3(a) shall be made successively, whenever an event referred to in this Section 2.3(a) occurs.

If, after the Effective Date and prior to the Expiration Time, the Corporation 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 2.3(a)(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 Corporation and the Rights Agent agree to amend, supplement or restate this Agreement in order to effect such treatment.

If an event occurs which would require an adjustment under both this Section 2.3 and Section 3.1, the adjustment provided for in this Section 2.3 shall be in addition to, and shall be made prior to, any adjustment required under Section 3.1.

In the event the Corporation shall at any time after the Effective Date 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In the event the Corporation shall at any time after the Effective Date and prior to the Separation Time fix a record date for
the issuance of rights, options or warrants (other than Rights) 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 Convertible Securities in respect of Common
Shares) at a price per Common Share (or, in the case of 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 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 Securities, including the price required to be paid to purchase such Convertible
Securities) would purchase at such Market Price per Common Share; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 Securities 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.

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 Corporation; provided, however, that, in the case of any Dividend Reinvestment Plan 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) In the event the Corporation shall at any time after the Effective Date 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)
of evidences of indebtedness, cash (other than an annual cash dividend or a dividend paid in Common Shares, but including any dividend
payable in securities other than Common Shares), assets or rights, options or warrants (excluding rights, options or warrants expiring
within 45 calendar days after such record date) to purchase Common Shares or Convertible Securities in respect of Common Shares, 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 evidences of indebtedness, cash,
assets, rights, options or warrants so to be distributed applicable to the securities purchasable upon exercise of one Right. Such adjustment
shall be made successively whenever such a record date is fixed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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. Any adjustment required
by Section 2.3 shall be made as of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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(a); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the record date for the applicable dividend or distribution, the case of an adjustment made pursuant to
Subsection 2.3(b) or (c), subject to readjustment to reverse the same if such distribution shall not be made.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) In the event the Corporation shall at any time after the Effective Date and prior to the Separation Time
issue any shares of capital stock (other than Common Shares), or rights, options or warrants to subscribe for or purchase any such capital
stock, or securities convertible into or exchangeable for any such capital stock, in a transaction referred to in Subsection 2.3(a)(i)
or (iv) or Subsections 2.3(b) or (c), if the Board of Directors acting in good faith determines that the adjustments contemplated by Subsections
2.3(a), (b) and (c) 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), such adjustments, rather than the adjustments contemplated
by Subsections 2.3(a), (b) and (c), shall be made. Subject to Subsections 5.4(b) and (c), the Corporation and the Rights Agent may, with
the prior approval of the holders of the Common Shares, amend this Agreement as appropriate to provide for such adjustments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) Each Right originally issued by the Corporation 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) 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 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 shares (fractional or otherwise)
or other securities upon the occurrence of the event requiring such adjustment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Notwithstanding anything contained in this Section 2.3 to the contrary, the Corporation 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) consolidation or subdivision of Common Shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) stock dividends; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) issuance of rights, options or warrants referred to in this Section 2.3,

hereafter made by the Corporation to holders of its Common Shares, subject to applicable taxation laws, shall not be taxable to such shareholders or shall subject such shareholders to a lesser amount of tax.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) Whenever an adjustment to the Exercise Price is made pursuant to this Section 2.3, the Corporation shall:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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, or confirmation in Book Entry Form, 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 absolute holder of record of the Common Shares or other securities, if applicable, represented thereon, 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(e) (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 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 succeeding Business Day on which the Common Share transfer books of the Corporation are open.

2.5 Execution, Authentication, Delivery and Dating of Rights Certificates

Rights will be evidenced, in the case of Rights in Book Entry Form, by a statement issued under the Rights Agent's direct registration system or, alternatively, if the Corporation determines to issue Rights Certificates, by the following procedures:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Rights Certificates shall be executed on behalf of the Corporation by its Chair of the Board of Directors,
Chief Executive Officer, President, Chief Financial Officer or any Vice-President and by its Corporate Secretary or any Assistant Secretary
under the corporate seal of the Corporation reproduced thereon. The signature of any of these officers on the Rights Certificates may
be manual or electronic. 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 either before or after the countersignature and delivery of such Rights Certificates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Promptly after the Corporation learns of the Separation Time, the Corporation will notify the Rights Agent
of such Separation Time and will deliver Rights Certificates executed by the Corporation and disclosure statements describing the Rights
to the Rights Agent for countersignature, and the Rights Agent shall countersign (manually or by electronic signature in a manner satisfactory
to the Corporation) and deliver such Rights Certificates and disclosure statements 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.

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

2.6 Registration, Transfer and Exchange

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) After the Separation Time, the Corporation will 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, at its office in the City of Toronto, is hereby appointed registrar for the Rights (the "**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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 Subsection 2.6(d), 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. Alternatively, in the case of the exercise of Rights in Book Entry Form, the Rights Agent shall provide the
holder or the designated transferee or transferees with one or more statements issued under the Rights Agent's direct registration
system evidencing the same aggregate number of Rights as did the direct registration system's records for the Rights transferred
or exchanged.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 reasonable fees and expenses of the Rights Agent) connected therewith.

2.7 Mutilated, Destroyed, Lost and Stolen Rights Certificates

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 countersign and deliver in exchange therefor a new Rights Certificate evidencing
the same number of Rights as did the Rights Certificate so surrendered.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) If there shall be delivered to the Corporation and the Rights Agent prior to the Expiration Time:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) such security or indemnity as may be reasonably required by each of them in their sole discretion 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) As a condition to the issuance of any new Rights Certificate under this Section 2.7, 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 reasonable fees and expenses of the Rights Agent) connected therewith.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 Corporation, 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 Corporation, the Rights Agent and any agent of the Corporation 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. As used in this Agreement, unless the context otherwise requires, the term "holder" of any Right shall mean the registered holder of such Right (or, prior to the Separation Time, of the associated Common Share).

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 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 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, destroy all cancelled Rights Certificates and, upon request of the Corporation, deliver a certificate of destruction to the Corporation.

2.10 Agreement of Rights Holders

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 Voting Share certificate representing such Right;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) that prior to due presentment of a Rights Certificate (or, prior to the Separation Time, the associated
Voting Share certificate) for registration of transfer, the Corporation, the Rights Agent and any agent of the Corporation or the Rights
Agent may deem and treat the Person in whose name the Rights Certificate (or, prior to the Separation Time, the associated Voting 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 Voting Share certificate made by anyone other than the Corporation or the Rights
Agent) for all purposes whatsoever, and neither the Corporation nor the Rights Agent shall be affected by any notice to the contrary;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) 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, acting in good faith, this Agreement may be supplemented or amended from
time to time pursuant to and as provided herein; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) that notwithstanding anything in this Agreement to the contrary, neither the Corporation 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 preliminary or permanent injunctions 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.

2.11 Rights Certificate Holder 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 Corporation which may at any time be issuable on the exercise of the Rights represented thereby, 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 Corporation or any right to vote at any meeting of shareholders of the Corporation whether for the election of directors or otherwise or upon any matter submitted to holders of Common Shares or any other shares of the Corporation at any meeting thereof, or to give or withhold consent to any action of the Corporation, or to receive notice of any meeting or other action affecting any holder of Common Shares or any other shares of the Corporation 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<br> ADJUSTMENTS TO THE RIGHTS**

3.1 Flip-in Event

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Subject to Subsection 3.1(b) and Section 5.1, in the event that prior to the Expiration Time a Flip-in
Event shall occur, each Right shall constitute, effective at the close of business on the tenth Trading Day after the Stock Acquisition
Date, the right to purchase from the Corporation, 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).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) a transferee or other successor in title, directly or indirectly, (a "**Transferee**") of Rights held by an Acquiring
Person (or any Affiliate or Associate of an Acquiring Person or any other Person acting jointly or in concert with an Acquiring Person
or any Affiliate or Associate of such other Person), where such Transferee becomes a transferee concurrently with or subsequent to the
Acquiring Person becoming such in a transfer that the Board of Directors acting in good faith 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 other Person acting jointly or in concert
with an Acquiring Person or any Affiliate or Associate of such other 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 any Transferee) shall thereafter have no right to exercise 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 or transfer or exchange which does not contain the necessary certifications set forth in the Rights Certificate establishing that such Rights are not null and void under this Subsection 3.1(b) shall be deemed to be an Acquiring Person for the purposes of this Subsection 3.1 and such Rights shall become null and void.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) From and after the Separation Time, the Corporation 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 1933 Securities Act, 1934 Exchange Act, BCBCA, Securities Act and the other applicable
securities laws or comparable legislation of each of the provinces and territories of Canada and in any other jurisdiction where the Corporation
is subject to such laws and the rules of the stock exchanges or quotation systems where the Common Shares are listed or quoted at such
time in respect of the issue of Common Shares upon the exercise of Rights in accordance with this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Any Rights Certificate that represents Rights Beneficially Owned by a Person described in either Subsection
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 or will be deemed to contain the following legend:

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 Shareholder Rights Agreement) or a Person who was acting jointly or in concert with an Acquiring Person or an Affiliate or Associate of such 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 Shareholder 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 Corporation 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 and provided further that the fact that such legend does not appear on a certificate is not determinative of whether any Rights represented thereby are void under this Section.

**Article 4<br> THE RIGHTS AGENT**

4.1 General

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Corporation hereby appoints the Rights Agent to act as agent for the Corporation and the holders of the Rights in accordance with
the terms and conditions hereof, and the Rights Agent hereby accepts such appointment. The

Corporation may from time to time appoint such co-Rights Agents ("**Co-Rights Agents**") as it may deem necessary or desirable. In the event the Corporation appoints one or more Co-Rights Agents, the respective duties of the Rights Agent and Co-Rights Agents shall be as the Corporation may determine with the approval of the Rights Agent and the Co-Rights Agent. The Corporation agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and other disbursements reasonably incurred in the administration and execution of this Agreement and the exercise and performance of its duties hereunder (including the fees and disbursements of any expert or advisor retained by the Rights Agent pursuant to Section 4.3(a)). The Corporation also agrees to indemnify the Rights Agent, and its officers, directors, employees, affiliates and agents for, and to hold it and them harmless against, any loss, liability or expense, incurred without gross negligence, bad faith or wilful misconduct on the part of the Rights Agent or such persons, for anything done or omitted by the Rights Agent or such persons in connection with the acceptance and administration of this Agreement, including legal costs and expenses, which right to indemnification will survive the termination of this Agreement and the resignation or removal of the Rights Agent. Any liability of the Rights Agent will be limited in the aggregate to an amount equal to the annual fee paid by the Corporation pursuant to this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 Corporation, instrument of assignment or transfer, power of attorney, endorsement,
affidavit, letter, notice, direction, consent, certificate, statement, or other paper or document believed by it to be genuine and to
be signed, executed and, where necessary, verified or acknowledged, by the proper Person or Persons.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Corporation 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 Corporation.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Any corporation into which the Rights Agent or any successor 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 or any successor Rights Agent is a party, or any corporation succeeding to the shareholder or stockholder services
business of the Rights Agent or any successor 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. In case at the time such successor Rights

Rights Agent may adopt the countersignature of the predecessor Rights Agent and deliver

such Rights Certificates so countersigned; and in case at that time any of the Rights Certificates 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In case at any time the name of the Rights Agent is changed and at such time any of the Rights Certificates
shall have been countersigned but not delivered, the Rights Agent may adopt the countersignature under its prior name and deliver Rights
Certificates so countersigned; and in case at that time any of the Rights Certificates shall not have 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 Corporation and the holders of certificates for Common Shares and the holders of Rights Certificates, by their acceptance thereof, shall be bound:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the Rights Agent may retain and consult with legal counsel (who may be legal counsel for the Corporation) and the opinion of such
counsel 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 and the Rights Agent may also, with the prior written consent of the Corporation (such consent not
to be unreasonably withheld), consult with such other experts as the Rights Agent may reasonably consider necessary or appropriate to
properly carry out the duties and obligations imposed under this Agreement and the Rights Agent shall be entitled to rely in good faith
on the advice of any such expert;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 Corporation prior to taking or suffering any action hereunder, such
fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and
established by a certificate signed by a Person believed by the Rights Agent to be the Chair of the Board of Directors, Chief Executive
Officer, President, Chief Financial Officer, any Vice-President, Treasurer, Corporate Secretary or any Assistant Secretary of the Corporation
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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) the Rights Agent will be liable hereunder for its own gross negligence, bad faith or wilful misconduct
and that of its officers, directors and employees;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 which countersignature

shall not be construed as a representation or warranty by the Rights Agent as to the validity of this Agreement or the Rights Certificate (except the due certification 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 Corporation only;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) the Rights Agent will not be under 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, which countersignature
shall not be construed as a representation or warranty by the Rights Agent as to the validity of this Agreement or the Rights Certificate
(except the due certification thereof)); nor will it be responsible for any breach by the Corporation 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 or any written notice from the Corporation or any holder that a Person has become an Acquiring Person); nor will it
by any act hereunder be deemed 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) the Corporation 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) the Rights Agent is hereby authorized and directed to accept instructions with respect to the performance
of its duties hereunder from any individual believed by the Rights Agent to be the Chair of the Board of Directors, President, Chief Executive
Officer, Chief Financial Officer, any Vice-President, Treasurer, Corporate Secretary or any Assistant Secretary of the Corporation, 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. It is understood that instructions to the Rights
Agent shall, except where circumstances make it impractical or the Rights Agent otherwise agrees, be given in writing and, where not in
writing, such instructions shall be confirmed in writing as soon as reasonably practicable after the giving of such instructions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 Corporation or become pecuniarily interested in any transaction
in which the Corporation may be interested, or contract with or lend money to the Corporation or otherwise act as fully and freely as
though it were not the Rights

Agent under this Agreement. Nothing herein shall preclude the Rights Agent from acting in any other capacity for the Corporation or for any other legal entity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the Rights Agent shall have no obligation to ensure or verify compliance with any applicable laws or regulatory
requirements on the issue, exercise or transfer of any Rights or Common Shares issuable upon the exercise thereof. The Rights Agent shall
be entitled to process all transfers and exercises of Rights upon the presumption that such transfers or exercises are permissible pursuant
to all applicable laws and regulatory requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) the Rights Agent shall have no obligation to ensure that the legends appearing on the Rights Certificates
or Common Shares comply with regulatory requirements or securities laws of any applicable jurisdiction; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) 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 Corporation resulting from any such act,
default, neglect or misconduct, provided reasonable care was exercised in the selection and continued employment thereof.

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) in writing mailed to the Corporation and to each transfer agent of Common Shares by registered or certified mail and to the holders of Rights in accordance with Section 5.9. The Corporation 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 and to the holders of 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, then by prior written notice to the Corporation the resigning Rights Agent (at the Corporation's expense) or the holder of any Rights (which holder shall, with such notice, submit such holder's Rights Certificate, if any, for inspection by the Corporation), may apply, at the Corporation's expense, to any court of competent jurisdiction for the appointment of a new Rights Agent. Any successor Rights Agent, whether appointed by the Corporation or by such a court, shall be a corporation incorporated under the laws of Canada or a province thereof authorized to carry on the business of a trust company in either the Province of British Columbia or 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 shall, upon payment in full of any outstanding amounts owing by the Corporation to the Rights Agent under this Agreement, 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 any successor Rights Agent, as the case may be.

4.5 Liability

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 (a) breach by any other party of securities law or other rule of any securities regulatory authority, (b) lost profits or (c) special, indirect, incidental, consequential, exemplary, aggravated or punitive losses or damages.

4.6 Compliance with Anti-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, the Rights Agent reasonably determines that such an act might cause it to be in non-compliance with any applicable anti-money laundering, anti-terrorist or economics sanctions legislation, regulation or guidelines. 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, anti-terrorist or economics sanctions legislation, regulation or guidelines, then it shall have the right to resign on 10 days' prior written notice to the Corporation, 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.

4.7 Privacy Legislation

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 direct any action that would contravene, or cause the other to contravene, applicable Privacy Laws. The Corporation 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<br> MISCELLANEOUS**

5.1 Redemption and Waiver

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Board of Directors acting in good faith may, with the prior approval of the holders of Voting Shares or of the holders of
Rights given in accordance with Section 5.1(i) or (j), as the case may be, at any time prior to the occurrence of a Flip-in Event as
to which the application of Section 3.1 has not been waived pursuant to the provisions of this Section 5.1, elect to redeem all but not
less than all of the then 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 in the event that 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**").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Board of Directors acting in good faith may, with the prior approval of the holders of Voting Shares given in accordance with
Section 5.1(i), determine, at any time prior to the occurrence of a Flip-in Event as to which the application of Section 3.1 has not
been waived pursuant to this Section 5.1, if such Flip-in Event would occur by reason of an acquisition of Voting Shares and/or Convertible
Securities otherwise than pursuant to a Take-over Bid made by means of a take-over bid circular to all holders of record of Voting Shares
and otherwise than in the circumstances set forth in Subsection 5.1(d), to waive the application of Section 3.1 to such Flip-in Event.
In the event that the Board of Directors proposes such a waiver, the Board of Directors shall extend the Separation Time to a date subsequent
to and not more than ten Business Days following the meeting of shareholders called to approve such waiver.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) 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, determine to waive the application of Section 3.1 to such particular Flip-in Event provided that the Flip-in Event
would occur by reason of a Take-over Bid made by way of take-over bid circular sent to all holders of Voting Shares (which for greater
certainty shall not include the circumstances described in Subsection 5.1(d)); 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(c), the Board of Directors shall be deemed to have waived
the application of Section 3.1 to any other Flip-in Event subsequently occurring by reason of any Take-over Bid which is made by means
of a take-over bid circular to all holders of Voting Shares prior to the expiry of any Take-over Bid in respect of which a waiver is,
or is deemed to have been, granted under this Subsection 5.1(c).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Notwithstanding the provisions of Subsections 5.1(b) and (c) hereof, upon written notice to the Rights Agent, 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
ten 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 such 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(d)
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 such 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The Board of Directors shall, without further formality, be deemed to have elected to redeem the Rights
at the Redemption Price on the date that a Person which has made a Permitted Bid, a Competing Permitted Bid or a Take-over Bid in respect
of which the Board of Directors has waived, or is deemed to have waived, pursuant

to Subsection 5.1(c) the application of Section 3.1, takes up and pays for Voting Shares in connection with such Permitted Bid, Competing Permitted Bid or Take-over bid, as the case may be.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) Where a Take-over Bid that is not a Permitted Bid or Competing Permitted Bid is withdrawn or otherwise terminated 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. Upon the Rights being redeemed pursuant to this Subsection 5.1(f), all the provisions of this Agreement shall
continue to apply as if the Separation Time had not occurred and Rights Certificates representing the number of Rights held by each holder
of record of Common Shares as of the Separation Time had not been mailed to each such holder and for all purposes of this Agreement the
Separation Time shall be deemed not to have occurred and the Corporation shall be deemed to have issued replacement Rights to the holders
of its then outstanding Common Shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) If the Board of Directors elects or is deemed to have elected to redeem the Rights, and, in circumstances in which Subsection
5.1(a) is applicable, such redemption is approved by the holders of Voting Shares or the holders of Rights in accordance with Subsection
5.1(i) or (j), as the case may be, 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 shall be to receive the Redemption Price.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) Within ten Business Days after the Board of Directors elects or is deemed to elect to redeem the Rights
or if Subsection 5.1(a) is applicable within ten Business Days after the holders of Common Shares or the holders of Rights have approved
a redemption of Rights in accordance with Section 5.1(i) or (j), as the case may be, the Corporation shall give notice of redemption to
the holders of the then outstanding Rights 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 herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of
redemption will state the method by which the payment of the Redemption Price will be made. The Corporation may not redeem, acquire or
purchase for value any Rights at any time in any manner other than specifically set forth in this Section 5.1 or in connection with the
purchase of Common Shares prior to the Separation Time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) If a redemption of Rights pursuant to Subsection 5.1(a) or a waiver of a Flip-in Event pursuant to Section 5.1(b) is proposed
at any time prior to the Separation Time, such redemption or waiver shall be submitted for approval to the holders of Voting Shares.
Such approval shall be deemed to have been given if the redemption or waiver is approved by the affirmative vote of a majority of the
votes cast by Independent Shareholders represented in person or by proxy at a meeting of such holders duly held in accordance with applicable
laws and the Corporation's articles.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) If a redemption of Rights pursuant to Subsection 5.1(a) is proposed at any time after the Separation Time, such redemption shall
be submitted for approval to the holders of Rights. Such approval shall be deemed to have been given if the redemption is approved by
holders of Rights by a majority of the votes cast by the

holders of Rights represented in person or by proxy at and entitled to vote at a meeting of such holders. For the purposes hereof, each outstanding Right (other than Rights which are Beneficially Owned by any Person referred to in Subsections (i) to (v) inclusive of the definition of Independent Shareholders) 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 Corporation's articles and under applicable laws, with respect to meetings of shareholders of the Corporation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) The Corporation shall not be obligated to make a payment of the Redemption Price to any holder of Rights
unless such holder is entitled to receive at least $10 in respect of all of the Rights held by such holder.

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 Corporation 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Corporation may, without the prior approval of the holders of Voting Shares or Rights, make amendments to this Agreement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) to correct any clerical or typographical error;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) which are required to maintain the validity of this Agreement as a result of any change in any applicable legislation or regulations
or rules thereunder; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) to cure any ambiguity, to correct or supplement any provision herein which may be defective or inconsistent
with any other provision herein, or to make any other provisions with respect to matters or questions arising under this Agreement, provided
that such action pursuant to this paragraph (iii) shall not adversely affect the interests of the holders of Voting Shares or Rights in
any material respect.

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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Subject to Subsection 5.4(a), the Corporation may, with the prior approval of the holders of Voting Shares, at any time before
the Separation Time, supplement, amend, vary, rescind or delete 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). Any approval of the holders of Voting Shares shall be deemed to have been given if the action requiring such approval is authorized by the affirmative vote of a majority of the votes cast by Independent Shareholders present or represented at and entitled to be voted at a meeting of the holders of Voting Shares duly called and held in compliance with applicable laws and the articles of the Corporation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Subject to Subsection 5.4(a), the Corporation may, with the prior approval of the holders of Rights, at any time on or after the
Separation Time, supplement, amend, vary, rescind or delete 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). 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 Corporation's articles and under applicable laws, with respect to meetings of shareholders of the Corporation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Any amendments made by the Corporation to this Agreement pursuant to Subsection 5.4(a)(ii) shall:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) if made before the Separation Time, be submitted to the shareholders of the Corporation 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 Corporation and the holders of Rights may, by resolution
passed by the majority referred to in Subsection 5.4(c), 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 (or any adjournment of such 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 as the case may be.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The Corporation shall give notice in writing to the Rights Agent of any supplement, amendment, deletion,
variation or rescission to this Agreement pursuant to this

Section 5.4 within five Business Days of the date of any such supplement, amendment, deletion, variation or rescission, provided that failure to give such notice, or any defect therein, shall not affect the validity of any such supplement, amendment, deletion, variation or rescission.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) Any amendment or supplement to this Agreement shall be subject to the receipt of any requisite approvals
or consent from any applicable regulatory authority including, without limitation, any necessary approvals of any stock exchange on which
the Common Shares are listed for trading.

5.5 Fractional Rights and Fractional Shares

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Corporation 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 Corporation 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Corporation 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 Corporation 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.

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 Corporation 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 Corporation or action or event contemplated by this Agreement shall be subject to the receipt of any requisite approval or consent from any governmental or regulatory

authority, including without limiting the generality of the foregoing, any necessary approvals of the Nasdaq Stock Market, or any other applicable stock exchange or market or national securities quotation system.

5.8 Notice of Proposed Actions

In case the Corporation shall propose after the Separation Time and prior to the Expiration Time to effect or permit (in cases where the Corporation's permission is required) any Flip-in Event or to effect the liquidation, dissolution or winding up of the Corporation or the sale of all or substantially all of the Corporation's assets, then, in each such case, the Corporation shall give to each holder of a Right, in accordance with Section 5.9 hereof, a notice of such proposed action, which shall specify the date on which such Flip-in Event, liquidation, dissolution, or winding up is to take place, and such notice shall be so given at least 20 Business Days prior to the date of taking of such proposed action by the Corporation.

**THE RIGHTS ARE SUBJECT TO REDEMPTION, AT THE OPTION OF THE CORPORATION, AND AMENDMENT OR 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, MAY BECOME VOID.**

**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 dated as of November 21, 2025, as the same may be amended or supplemented from time to time (the "Shareholder Rights Agreement"), between NioCorp Developments Ltd., a corporation incorporated under the laws of the Province of British Columbia (the "Corporation") and Computershare Trust Company of Canada, a trust company existing 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 Corporation 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 Corporation (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, together with payment of the Exercise Price by certified cheque, bank draft or money order payable to the Corporation, at the Rights Agent's principal office in any of the city of Toronto. Until adjustment thereof in certain events as provided in the Shareholder Rights Agreement, the Exercise Price shall be:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) until the Separation Time, an amount equal to three times the Market Price (as such term is defined in
the Shareholder Rights Agreement), from time to time, per Common Share; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) from and after the Separation Time, an amount equal to three times the Market Price, as at the Separation
Time, per Common Share.

In certain circumstances described in the Shareholder Rights Agreement, each Right evidenced hereby may entitle the registered holder thereof to purchase or receive assets, debt securities or shares in the capital of the Corporation other than Common Shares, or more or less than one Common Share, all 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 Corporation and the holders of the Rights Certificates. Copies of the Shareholder Rights Agreement are on file at the registered office of the Corporation and are available upon request.

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 Rights Certificate may be, and under certain circumstances are required to be, redeemed by the Corporation at a redemption price of $0.00001 per Right.

No fractional Common Shares will be issued upon the exercise of any Right or 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 Corporation 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.

## Exhibit 99.1

**Exhibit 99.1**

**NioCorp Adopts Limited-Duration Shareholder Rights Plan**

*Board acts to protect and maximize value for shareholders*

CENTENNIAL, Colo. (November 21, 2025) – NioCorp Developments Ltd. ("**NioCorp**" or the "**Company**") (**Nasdaq: NB**), a leading U.S. critical minerals developer, announced today that its board of directors (the "**Board**") has adopted a limited-duration shareholder rights plan (the "**Plan**") effective immediately.

The Board adopted the Plan to help ensure that all shareholders of the Company are treated equally and fairly in the event of any unsolicited takeover bid or other attempt to acquire control of the Company (including by way of a "creeping takeover bid"). In respect of such transactions, the Plan is intended to, among other things:

● encourage potential bidders to treat the Company's shareholders fairly and equally and preserve control premiums and value for shareholders; and

● provide the Board and shareholders adequate time to appropriately respond on an informed basis.

The Plan was not adopted in response to any specific takeover bid or other proposal to acquire control of the Company, and the Company is not aware of any such pending or contemplated takeover bid or other proposal.

Pursuant to the Plan, one right (a "**Right**") will be issued in respect of each outstanding common share of the Company (a "**Common Share**") as of the close of business on the record date, being December 4, 2025. Thereafter, one Right will automatically attach to each new Common Share issued by the Company. Subject to the terms of the Plan, each Right will become exercisable if a person (the "**Acquiring Person**"), together with certain related persons (including persons "acting jointly or in concert" as defined in the Plan), acquires beneficial ownership of 20% or more of the outstanding Common Shares without complying with the permitted bid provisions of the Plan. In such circumstances, each Right will entitle the holder (other than the Acquiring Person) to purchase additional Common Shares at a discount to the then prevailing market price.

Under the Plan, a "Permitted Bid" is a takeover bid made in compliance with the Canadian takeover bid regime. Specifically, a Permitted Bid is a take-over bid that is made to all shareholders, that is open for 105 days (or such shorter period as is permitted under the Canadian take-over bid regime) and that contains certain conditions, including that no Common Shares will be taken up and paid for unless more than 50% of the Common Shares that are held by independent shareholders are tendered to the take-over bid.

The issuance of the Rights will not affect trading of the Common Shares, and no further action is required by shareholders. The Plan has a term of six months and will expire on May 21, 2026, or earlier as described in the agreement governing the Plan.

The Plan is contained in an agreement between the Company and Computershare Investor Services Inc., as rights agent, dated November 21, 2025. The full text of the Plan is available on the Company's profile on SEDAR+ at www.sedarplus.ca and on EDGAR at www.sec.gov. The summary of the Plan contained herein is qualified in its entirety by the full text of the Plan.

**ABOUT NIOCORP**

NioCorp is developing the Elk Creek Project that is expected to produce niobium, scandium, and titanium. The Company also is evaluating the potential to produce several rare earths from the Elk Creek Project. Niobium is used to produce specialty alloys as well as High Strength, Low Alloy steel, which is a lighter, stronger steel used in automotive, structural, and pipeline applications. Scandium is a specialty metal that can be combined with Aluminum to make alloys with increased strength and improved corrosion resistance. Scandium is also a critical component of advanced solid oxide fuel cells. Titanium is used in various lightweight alloys and is a key component of pigments used in paper, paint and plastics and is also used for aerospace applications, armor, and medical implants. Magnetic rare earths, such as neodymium, praseodymium, terbium, and dysprosium are critical to the making of neodymium-iron-boron magnets, which are used across a wide variety of defense and civilian applications.
