Item 1.01. Entry into a Material Definitive Agreement.

The information contained in Item 3.03

below is incorporated herein by reference.

Item 3.03. Material Modification to Rights of Security Holders.

As previously disclosed,

the Board of Directors (the “Board”) of NioCorp Developments Ltd. (the “Company”) previously 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 “Original Rights Plan Agreement”), by and between the Company and

Computershare Investor Services Inc., as rights agent (or any successor rights agent) (the “Rights Agent”).

On April 6, 2026, following

approval by the Company’s shareholders at the Annual Meeting (as defined below), the Company entered into an Amended and

Restated Shareholder Rights Plan Agreement (the “Amended Rights Plan Agreement”), by and between the Company and the

Rights Agent, which amends and restates the Original Shareholder Rights Plan Agreement in its entirety.

The Rights Plan pursuant

to the Original Rights Plan Agreement had an initial term of six months and would have expired on May 21, 2026, or earlier upon

the redemption of the Rights (as defined within the Amended Rights Plan Agreement) or, provided that a Flip-In Event (as defined

within the Amended Rights Plan Agreement) has not occurred, at such date or time as the Board may determine in its sole discretion

(the “Expiration Time”). The Amended Rights Plan Agreement amends the definition of the Expiration Time of the Rights

Plan to be 5:00 p.m. (Toronto time) on the date of the Company’s annual general meeting of shareholders held in 2027, or

earlier upon the redemption of the Rights, or provided that a Flip-In Event has not occurred, at such date or time as the Board

may determine in its sole discretion.

The descriptions of the

Rights and the Rights Plan are incorporated herein by reference to the description under the heading “Particulars of Matters

to Be Acted Upon—VI – Approve Amendment and Extension of Company’s Shareholder Rights Plan” in the Company’s

definitive proxy statement on Schedule 14A, filed with the Securities and Exchange Commission on February 25, 2026, and are qualified in their entirety by reference to the full text of the Amended 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.

Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

April 6, 2026, at the Annual Meeting, the Company’s shareholders considered and approved the NioCorp Developments Ltd. Long

Term Incentive Plan, as amended (the “2017 Amended Long-Term Incentive Plan”), which amended and restated the prior

amendment and restatement of the NioCorp Developments Ltd. Long Term Incentive Plan that was approved by the Company’s shareholders

on January 19, 2024 (the “2017 Long-Term Incentive Plan”).

Under

the 2017 Amended Long-Term Incentive Plan, the Board may in its discretion from time to time grant options (“Options”)

to purchase Common Shares, without par value, of the Company (“Common Shares”), share units (in the form of restricted

share units (“RSUs”) and performance share units (collectively with RSUs, “Share Units”)) and dividend

equivalents to directors, employees and certain other service providers (as defined in the 2017 Amended Long-Term Incentive Plan)

of the Company and affiliated entities selected by the Board. Subject to adjustment as provided in the 2017 Amended Long-Term Incentive

Plan, the number of Common Shares available under the 2017 Amended Long-Term Incentive Plan for awards of (1) Options, (2) Share

Units, and (3) dividend equivalents, will not exceed, in the aggregate, 11,300,000 Common Shares, minus, as of April 6, 2026, one

Common Share for every one Common Share subject to an award granted under the 2017 Long-Term Incentive Plan after February 9, 2026

and before April 6, 2026. Such Common Shares may be shares of original issuance or treasury shares or a combination of the two.

The finite share limit described above replaced the “evergreen” share limit that had previously been used the 2017

Long-Term Incentive Plan. Subject to the share counting rules of the 2017 Amended Long-Term Incentive Plan, the aggregate number

of Common Shares available under the 2017 Amended Long-Term Incentive Plan will be reduced by one Common Share for every one Common

Share subject to an award granted under the 2017 Amended Long-Term Incentive Plan.

Under

the 2017 Amended Long-Term Incentive Plan, subject to adjustment as provided in the 2017 Amended Long-Term Incentive Plan, the

aggregate number of Common Shares actually issued or transferred by the Company upon the exercise of stock options intended to

qualify as “incentive stock options” under Section 422 of the United States Internal Revenue Code will not exceed 11,300,000

Common Shares. The 2017 Amended Long-Term Incentive Plan also made the following other changes from the 2017 Long-Term Incentive

Plan (in addition to certain non-material amendments of a housekeeping nature):

● implemented updated share counting and recycling provisions, including to provide as follows: (i)

if any award under the 2017 Amended Long-Term Incentive Plan (in whole or in part) is cancelled or forfeited, expires, is settled

for cash, or is unearned, the Common Shares subject to such award will, to the extent of such cancellation, forfeiture, expiration,

cash

settlement, or unearned amount, again be available under the 2017 Amended Long-Term Incentive Plan; (ii) Common Shares withheld

by the Company, tendered or otherwise used in payment of the exercise price of an Option will not be added (or added back, as applicable)

to the aggregate number of Common Shares available under the 2017 Amended Long-Term Incentive Plan; (iii) Common Shares withheld

by the Company, tendered or otherwise used to satisfy tax withholding with respect to awards will not be added (or added back,

as applicable) to the aggregate number of Common Shares available under the 2017 Amended Long-Term Incentive Plan; and (iv) Common

Shares reacquired by the Company on the open market or otherwise using cash proceeds from the exercise of Options will not be added

(or added back, as applicable) to the aggregate number of Common Shares available under the 2017 Amended Long-Term Incentive Plan;

● eliminated certain “evergreen” limitations on outstanding shares from time to time

that could be reserved for issuance with respect to Share Units or to individual participants, as well as certain Toronto-Stock-Exchange-related

limitations on shares issuable to insiders;

● included a limit on the annual compensation of the Company’s non-employee directors;

● updated the amendment provisions to more closely align with the rules of The Nasdaq Stock Market (“Nasdaq”); and

● clarified that the Company may take advantage of the applicable Nasdaq exemptions to shareholder approval of equity compensation

plans.

The

Board will generally be able to amend the 2017 Amended Long-Term Incentive Plan, subject to shareholder approval in certain circumstances

as further described in the 2017 Amended Long-Term Incentive Plan.

The

foregoing description of the 2017 Amended Long-Term Incentive Plan is not complete and is in all respects qualified in its entirety

by the actual provisions of the 2017 Amended Long-Term Incentive Plan, a copy of which is filed as Exhibit 10.1 hereto and is incorporated

by reference herein.

Item 5.07 Submission of Matters to a Vote of Security Holders.

Company held its Annual Meeting of Shareholders (the “Annual Meeting”). As of the record date for the Annual Meeting,

PLAN AGREEMENT

THIS AMENDED AND RESTATED SHAREHOLDER RIGHTS

the exercise of its fiduciary duties to the Corporation, has determined that it is in the best interests of the Corporation to

continue the shareholder protection rights plan by adopting an amended and restated shareholder rights plan to take effect immediately

upon receipt of approval of the Independent Shareholders (as hereinafter defined) to effect the continued distribution of rights

under the Shareholder Rights Plan Agreement originally dated November 21, 2025 (the “Original Plan”) as amended

and restated herein (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:

(a) authorized the issuance, effective at the close of business (Toronto time) on December 4, 2025

(the “Record Time”), of one Right (as hereinafter defined) in respect of each Common Share (as hereinafter defined)

outstanding at the Record Time, such issuance having been made to shareholders of record at the Record Time;

(b) authorized the issuance of one Right in respect of each Voting Share (as hereinafter defined) of

the Corporation issued after the Record Time and prior to the earlier of the Separation Time (as hereinafter defined) and the Expiration

Time (as hereinafter defined); and

to the terms and subject to the conditions set forth herein;

AND WHEREAS each Right entitles the

holder thereof, after the Separation Time, to purchase securities of the Corporation pursuant to the terms and subject to the conditions

set forth herein;

AND WHEREAS the Corporation desires

to appoint the Rights Agent to act on behalf of the Corporation and the holders of Rights, and the Rights Agent is willing to so

act, in connection with the issuance, transfer, exchange and replacement of Rights Certificates, the exercise of Rights and other

matters referred to herein;

- 5 -

(E) a Convertible Security Acquisition;

provided, however,

that if a Person becomes the Beneficial Owner of 20% or more of the then outstanding Voting Shares by reason of one or any

Shares thereafter increases by more than 1% of the number of Voting Shares outstanding (other than pursuant to one of a Voting

Share Reduction, a Permitted Bid Acquisition, an Exempt Acquisition, a Pro Rata Acquisition or a Convertible Security Acquisition

or any combination thereof), then as of the date such Person becomes the Beneficial Owner of such additional Voting Shares, such

Person shall become an “Acquiring Person”;

(iii) for a period of ten days after the Disqualification Date (as defined below), any Person who becomes

the Beneficial Owner of 20% or more of the outstanding Voting Shares as a result of such Person becoming disqualified from relying

on Subsection 1.1(g)(iii)(B) where such disqualification results solely because such Person is making or has announced a current

intention to make a Take-over Bid, either alone or by acting jointly or in concert with any other Person, unless such disqualified

Person during such 10-day period acquires an additional 1% or more of the then outstanding Voting Shares. For the purposes of this

with the Corporation; or

(v) a Person (a “Grandfathered Person”) who is the Beneficial Owner of 20% or more

of the outstanding Voting Shares determined as at the Effective Date, provided, however, that this exception shall not be, and

shall cease to be, applicable to a Grandfathered Person in the event that such Grandfathered Person shall, after the Effective

Date: (1) cease to own more than 20% of the outstanding Voting Shares, or (2) become the Beneficial Owner of any additional Voting

Shares that increases its Beneficial Ownership of Voting Shares by more than 1% of the number of Voting Shares outstanding (other

than through one or any combination of a Permitted Bid Acquisition, an Exempt Acquisition, a Voting Share Reduction, a Pro Rata

Acquisition or a Convertible Security Acquisition);

(b) “Affiliate”, when used to indicate a relationship with a specified Person, shall

mean a Person that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common

control with, such specified Person;

and the Rights Agent, as amended, supplemented or restated from time to time; “hereof”, “herein”, “hereto”

and similar expressions mean and refer to this Agreement as a whole and not to any particular part of this Agreement;

(d) “annual cash dividend” shall mean cash dividends paid in any fiscal year of

the Corporation to the extent that such cash dividends do not exceed, in the aggregate on a per share basis, in any fiscal year,

on its Common Shares in its immediately preceding fiscal year;

(ii) 300% of the arithmetic mean of the aggregate amounts of the cash dividends, on a per share basis,

declared payable by the Corporation on its Common Shares in its three immediately preceding fiscal years; and

(iii) 100% of the aggregate consolidated net income of the Corporation, before extraordinary items, for

its immediately preceding fiscal year divided by the number of Common Shares outstanding as at the end of such fiscal year;

(e) “Associate” shall mean, when used to indicate a relationship with a specified

Person, any relative of such specified Person who has the same home as such specified Person, or any person to whom such specified

Person is married, or any person with whom such specified Person is living in a conjugal relationship

- 7 -

outside marriage, or any

relative of such spouse or other Person who has the same home as such specified Person;

(f) “BCBCA” shall mean the Business Corporations Act, S.B.C. 2002, c. 57,

as amended, and the regulations thereunder, and any comparable or successor laws or regulations thereto;

(g) A Person shall be deemed the “Beneficial Owner” of, and to have “Beneficial

Ownership” of, and to “Beneficially Own”:

(i) any securities as to which such Person or any of such Person’s Affiliates or Associates is

the owner at law or in equity;

(ii) any securities as to which such Person or any of such Person’s Affiliates or Associates has

the right to become the owner at law or in equity (where such right is exercisable immediately or within a period of 60 days, whether

or not on condition or on the happening of any contingency) pursuant to any agreement, arrangement, pledge or understanding, whether

or not in writing, or upon the exercise of any conversion, exchange or purchase right (other than the Rights) attaching to a Convertible

Security, including but not limited to any lock-up agreement or similar agreement, arrangement or understanding that is not a Permitted

“Beneficially Own”, any security:

(A) where such security has been deposited or tendered pursuant to any Take-over Bid or where the holder

of such security has agreed pursuant to a Permitted Lock-Up Agreement to deposit or tender such security pursuant to a Take-over

Bid, in each case made by such Person, made by any of such Person’s Affiliates or Associates or made by any other Person

acting jointly or in concert with such Person, until such deposited or tendered security has been taken up or paid for, whichever

for such Other Accounts;

(3) such Person is a pension plan or fund registered under the laws of Canada or any province thereof

THE RIGHTS

2.1 Issuance of Rights; Legend on Share Certificates

(a) One Right shall be issued at the Record Time in respect of each Voting Share issued and outstanding

at 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.

(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

- 23 -

on, written on or otherwise

affixed to them (i) the legend set forth in Section 2.1(b) of the Original Plan, which legend shall be deemed to be amended for

all purposes to read the same as the following legend, or (ii) 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 an Amended and Restated Shareholder Rights Plan

Agreement dated as of April 6, 2026 (amending and restating the Shareholder Rights Plan Agreement originally dated 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.

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

(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.

(b) Until the Separation Time:

- 24 -

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

(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.

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.

(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):

(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

- 25 -

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

(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.

(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:

(i) the Rights Certificate evidencing such Rights;

(ii) an election to exercise such Rights (an “Election to Exercise”) substantially

in the form attached to the Rights Certificate appropriately completed and duly executed by the holder or 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

(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.

(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:

(i) requisition from the transfer agent of the Common Shares certificates representing the number of

Common Shares to be purchased (the

- 26 -

Corporation hereby irrevocably authorizing its transfer agent to comply with all such requisitions);

(ii) when appropriate, requisition from the Corporation the amount of cash, if any, to be paid in lieu

of issuing fractional Common Shares;

(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;

(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

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

(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.

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

(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;

(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;

(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;

(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;

- 27 -

(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

(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.

(a) In the event the Corporation shall at any time after the Effective Date and prior to the Expiration

Time:

(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;

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

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

(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

- 28 -

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.

(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:

- 29 -

(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

(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.

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

- 30 -

purchasable upon exercise of one Right. Such adjustment shall be made successively whenever such a record date

is fixed.

(d) Notwithstanding anything herein to the contrary, no adjustment in the Exercise Price shall be required

unless such adjustment would require an increase or decrease of at least one per cent in the Exercise Price; provided, however,

that any adjustments which by reason of this Subsection 2.3(d) are not required to be made shall be carried forward and taken into

account in any subsequent adjustment. All calculations under Section 2.3 shall be made to the nearest cent or to the nearest ten-thousandth

of a share. Any adjustment required by Section 2.3 shall be made as of:

(i) the payment or effective date for the applicable dividend, subdivision, change, combination or

issuance, in the case of an adjustment made pursuant to Subsection 2.3(a); or

(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.

(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.

(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.

(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.

(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

- 31 -

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.

(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:

(i) consolidation or subdivision of Common Shares;

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

into or exchangeable for Common Shares;

(iii) stock dividends; or

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

hereafter made by the 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.

(j) Whenever an adjustment to the Exercise Price is made pursuant to this Section 2.3, the Corporation

shall:

(i) promptly prepare a certificate setting forth such adjustment and a brief statement of the facts

accounting for such adjustment; and

(ii) promptly file with the Rights Agent and with each transfer agent for the Common Shares a copy of

such certificate and mail a brief summary thereof to each holder of Rights who requests a copy;

Failure to file such certificate

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

change.

2.4 Date on Which Exercise Is Effective

Each Person in whose name any certificate,

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

- 32 -

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:

(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.

(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.

2.6 Registration, Transfer and Exchange

(a) After the Separation Time, the Corporation will cause to be kept a register (the “Rights

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.

(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

- 33 -

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.

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.

(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

(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.

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

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

and

(ii) such security 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.

may require the payment of a sum sufficient to cover any tax

- 34 -

or other governmental charge that may be imposed in relation thereto

and any other expenses (including the reasonable fees and expenses of the Rights Agent) connected therewith.

(d) Every new Rights Certificate issued pursuant to this Section 2.7 in lieu of any destroyed, lost

or stolen Rights Certificate shall evidence the contractual obligation of the 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:

(a) to be bound by and subject to the provisions of this Agreement, as amended from time to time in

accordance with the terms hereof, in respect of all Rights held;

(b) that prior to the Separation Time, each Right will be transferable only together with, and will

be transferred by a transfer of, the associated Voting Share certificate representing such Right;

provided herein;

(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

- 35 -

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;

(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);

(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

(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,

ADJUSTMENTS TO THE RIGHTS

3.1 Flip-in Event

(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

- 36 -

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).

(b) Notwithstanding anything in this Agreement to the contrary, upon the occurrence of any Flip-in

Event, any Rights that are or were Beneficially Owned on or after the earlier of the Separation Time or the Stock Acquisition Date

by:

(i) an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any other Person acting

jointly or in concert with an Acquiring Person or any Affiliate or Associate of such other Person); or

(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.

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

- 37 -

listed or quoted at such time in respect of the issue of Common Shares upon the exercise of Rights

in accordance with this Agreement.

(d) Any Rights Certificate that represents Rights Beneficially Owned by a Person described in either

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.

THE RIGHTS AGENT

4.1 General

(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

- 38 -

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.

(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.

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

(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 Agent succeeds to the agency created by this Agreement any of the Rights Certificates have been countersigned

but not delivered, any successor 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.

(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.

- 39 -

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:

(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;

(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;

and that of its officers, directors and employees;

(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;

(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

- 40 -

(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;

(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;

(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;

(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;

(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;

(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

- 41 -

(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.

- 42 -

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.

MISCELLANEOUS

5.1 Redemption and Waiver

(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”).

(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

- 43 -

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.

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).

(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.

(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.

(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

- 44 -

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.

(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.

(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.

(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.

(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.

- 45 -

(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

(a) The Corporation may, without the prior approval of the holders of Voting Shares or Rights, make

amendments to this Agreement:

(i) to correct any clerical or typographical error;

(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

(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.

(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.

- 46 -

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.

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

(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;

(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

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.

deletion, variation or rescission to this Agreement pursuant to this Section 5.4 within five Business Days of the date of any such

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.

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

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.

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

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 Amended and Restated Shareholder Rights Plan Agreement dated

as of April 6, 2026 (amending and restating the Shareholder Rights Plan Agreement originally dated 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:

(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

(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.

This Rights Certificate shall not be valid

or obligatory for any purpose until it shall have been countersigned by the Rights Agent. WITNESS the facsimile signature of the

of any leave of absence or disability of any Participant. Without limiting the generality of the foregoing, the Board shall be

entitled to determine:

(i) whether or not any such leave of absence shall constitute a Termination within the meaning of the

Plan; and

(ii) the impact, if any, of any such leave of absence on Grants issued under the Plan made to any Participant

who takes such leave of absence (including, without limitation, whether or not such leave of absence shall cause any Grants to

provided that, with respect to

Options that are intended to be Incentive Stock Options, the treatment of any such leave of absence shall comply with Code Section

422 and the regulations issued thereunder;

(g) amend the terms of any Grant Agreement or other documents evidencing Grants; and

(h) determine whether, and the extent to which, adjustments shall be made pursuant to Section 5 and

the Plan or any Grant shall be made in its sole discretion and shall be conclusively binding upon all persons.

3.3 The Board may prescribe terms for Grant Agreements in respect of Eligible Persons who are subject

to the laws of a jurisdiction other than Canada in connection with their participation in the Plan that are different than the

terms of the Grant Agreements for Eligible Persons who are subject to the laws of Canada in connection with their participation

in the Plan, and/or deviate from the terms of the Plan set out herein, for purposes of compliance with Applicable Law in such other

jurisdiction or where, in the Board’s opinion, such terms or deviations are necessary or desirable to obtain more advantageous

treatment for the Corporation, an Affiliate or the Eligible Person in respect of the Plan under the Applicable Law of the other

jurisdiction.

Notwithstanding the foregoing,

the terms of any Grant Agreement authorized pursuant to this Section 3.3 shall be consistent with the Plan having regard to the

Applicable Law of the jurisdiction in which such Grant Agreement is applicable and in no event shall contravene the Applicable

Law of Canada.

3.4 The Board may, in its discretion, subject to Applicable Law, delegate its powers, rights and duties

under the Plan, in whole or in part, to a committee of the Board, or to a person or persons, as it may determine, from time to

time, on terms and conditions as it may determine, except that the Board shall not, and shall not be permitted to delegate any

such powers, rights or duties with respect to the grant, amendment, administration or settlement of any Grant to the extent delegation

is not consistent with Applicable Law and any such purported delegation or action shall not be given effect, and provided that

the composition of the committee of the Board, person or persons, as the case may be, shall comply with Applicable Law. In addition,

provided it complies with the foregoing, the Board may appoint or engage a trustee, custodian or administrator to administer or

implement the Plan or any aspect of it.

3.5 In addition, the Board is authorized to take any action it determines in its sole discretion to

4.1.2 Subject to the share counting rules set forth in Section 4.2 of this Plan, the aggregate number

of Shares available under Section 4.1.1 of this Plan will be reduced by one Share for every one Share subject to an award granted

under this Plan.

4.2 Share Counting Rules.

4.2.1 Except as provided in Section 7.11 of this Plan, if any Grant under this Plan (in whole or in part)

is cancelled or forfeited, expires, is settled for cash, or is unearned, the Shares subject to such award will, to the extent of

such cancellation, forfeiture, expiration, cash settlement, or unearned amount, again be available under Section 4.1.1 above.

4.2.2 Notwithstanding anything to the contrary contained in this Plan: (a) Shares withheld by the Corporation,

tendered or otherwise used in payment of the Exercise Price of an Option will not be added (or added back, as applicable) to the

aggregate number of Shares available under Section 4.1.1 of this Plan; (b) Shares withheld by the Corporation, tendered or

otherwise used to satisfy tax withholding with respect to Grants under this Plan will not be added (or added back, as applicable)

aggregate number of Shares available under Section 4.1.1 of this Plan.

in exchange for Shares based on fair market value, such Shares will not count against the aggregate limit under Section 4.1.1 of

this Plan.

4.3 Limit on Incentive Stock Options. Notwithstanding anything to the contrary contained

in this Plan, and subject to adjustment as provided in Section 5.1 of this Plan, the aggregate number of Shares actually issued

or transferred by the Corporation upon the exercise of Incentive Stock Options will not exceed 11,300,000 Shares.

contained in this Plan, in no event will any non-employee Director in any one calendar year be granted compensation, including

cash compensation, for such service having an aggregate maximum value (measured at the Grant Date as applicable, and calculating

the value of any Grants based on the grant date fair value for financial reporting purposes) in excess of US$750,000; provided,

however, that this limit shall not apply to (a) distributions of previously deferred compensation under a deferred compensation

plan maintained by the Corporation, (b) compensation received by the Director in his or her capacity as an executive officer or

employee of the Corporation or (c) any compensation resulting from non-preferential dividends or dividend equivalents associated

with outstanding equity awards.

5. ALTERATION OF CAPITAL AND CHANGE IN CONTROL

5.1 Notwithstanding any other provision of the Plan, and subject to Applicable Law, in the event of

any change in or impact to the Shares by reason of any dividend (other than dividends in the ordinary course), split, recapitalization,

reclassification, amalgamation, arrangement, merger, consolidation, spin-off, split-off, spin-out, split-up, reorganization, partial

or complete liquidation or other distribution of assets, issuance of rights or warrants to purchase securities, combination or

exchange of Shares or distribution of rights to holders of Shares or any other relevant changes to or impact to the authorized

or issued capital of the Corporation, if the Board shall determine that an equitable adjustment should be made, such adjustment

shall, subject to Applicable Law, be made by the Board to (i) the number of Shares subject to the Plan; (ii) the securities into

which the Shares are changed or are convertible or exchangeable; (iii) any Options then outstanding; (iv) the Exercise Price in

respect of such Options; (v) the number of Share Units outstanding under the Plan; and/or (vi) other award terms, and any such

adjustment shall be conclusive and binding for all purposes of the Plan; provided, however, that any such adjustment to

the number specified in Section 4.3 of this Plan will be made only if and to the extent that such adjustment would not cause any

Option intended to qualify as an Incentive Stock Option to fail to so qualify. Moreover, in the event of any such transaction or

event or in the event of a Change in Control, the Board may provide in substitution for any or all outstanding Grants under this

Plan such alternative consideration (including cash), if any, as it, in good faith, may determine to be equitable in the circumstances

and shall require in connection therewith the surrender of all awards so replaced in a manner that complies with Code Section 409A

(if applicable); provided that, with respect to any Grant that is, or is intended to be, subject to Section 7 of the Tax

Act, any substitution of such Grant for another award shall comply with the requirements of Section 7(1.4) of the Tax Act and any

settlement of such Grant for a cash payment shall comply with the requirements of Section 7(1)(b) of the Tax Act. In addition,

for each Option with an Exercise Price greater than the consideration offered in connection with any such transaction or event

or Change in Control, the Board may in its discretion elect to cancel such Option without any payment to the person holding such

Option.

5.2 Nothing in the Plan shall require the Corporation to issue fractional Shares in satisfaction of

its obligations under the Plan. Any fractional interest in a Share that would, except for the provisions of this Section 5.2, be

deliverable upon the exercise of any Grant shall be cancelled and not deliverable by the Corporation.

5.3 In the event of a Change in Control prior to the Vesting of a Grant, and subject to the terms of

a Participant’s written employment agreement or contract for services with the

Corporation or an Affiliate, notwithstanding

the conditions as to vesting of Options and Share Units contained in any individual Grant Agreement, if at any time within one

year after the date of a Change in Control: (i) a Participant’s Termination Date occurs for any reason other than for Cause

or (ii) a Participant resigns for Good Reason, all outstanding Options and Share Units, as applicable, held by such Participant

shall become Vested as of the date of such Participant’s Termination Date and the terms of this Plan applicable to Vested

Options and Vested Share Units shall apply to such Options and Share Units; provided that in the event that any Share Units are

subject to Performance Conditions, then the vesting of such Share Units shall accelerate only to the extent that such Performance

Conditions have been satisfied and further provided that if a Performance Condition is, in the Board’s discretion, capable

of being partially performed, then vesting shall be accelerated on a pro rata basis to reflect the degree to which the Performance

Condition has been satisfied, as determined by the Board.

6. CLAWBACK

6.1 Clawback.

It is a condition of each Grant

that if:

(i) The Participant fails to comply with any applicable Restrictive Covenant;

(ii) the Participant is Terminated for Cause, or the Board reasonably determines after the Termination

Date that the Participant’s employment could have been Terminated for Cause;

(iii) the Board reasonably determines that the Participant engaged in conduct that causes material financial

or reputational harm to the Corporation or its Affiliates, or engaged in gross negligence, willful misconduct or fraud in respect

of the performance of the Participant’s duties for the Corporation or an Affiliate of the Corporation; or

(iv) the Corporation’s financial statements (the “Original Statements”) are

required to be restated (other than solely as a result of a change in accounting policy by the Corporation or under International

Financial Reporting Standards applicable to the Corporation) and such restated financial statements (the “Restated Statements”)

disclose, in the opinion of the Board acting reasonably, materially worse financial results than those contained in the Original

Statements, then the Board may, in its sole discretion, to the full extent permitted by governing law and to the extent it determines

that such action is in the best interest of the Corporation, and in addition to any other rights that the Corporation or an Affiliate

may have at law or under any agreement, take any or all of the following actions, as applicable:

(A) reduce the number or value of, or cancel and terminate, any one

or more unvested Grants of Options or Share Units on or prior to the applicable maturity or Vesting Dates, or cancel or terminate

any outstanding Grants which have Vested in the twelve (12) months prior to (x) the date on which the Participant fails to comply

with a Restrictive Covenant, (y) the Participant’s

Termination Date or the date on which the Board makes a determination under paragraph (ii) or (iii) above, or (z) the date on which

the Board determines that the Corporation’s Original Statements are required to be restated, in the event paragraph (iv)

above applies (each such date provided for in clause (x), (y) and (z) of this paragraph (a) being a “Relevant Equity Recoupment

Date”); and/or

(B) require payment to the Corporation of the value of any Shares of the Corporation acquired by the Participant pursuant to a

Grant in the twelve (12) months prior to a Relevant Equity Recoupment Date (less any amount paid by the Participant to acquire

such Shares and less the amount of tax withheld pursuant to the Tax Act or other relevant taxing authority in respect of such Shares).

6.2 Other Recoupment.

Notwithstanding anything in this

Plan to the contrary, any Grant Agreement (or any part thereof) may provide for the cancellation or forfeiture of an award or the

forfeiture and repayment to the Corporation of any gain or earnings related to an award, or other provisions intended to have a

similar effect, upon such terms and conditions as may be determined by the Board in accordance with (i) any Corporation clawback

or recoupment policy or policies as adopted from time to time, including any policy adopted to comply with the requirements of

any applicable laws, rules, regulations, stock exchange listing standards or otherwise (in each case, the “Clawback Policy”),

or (ii) any applicable laws that impose mandatory clawback or recoupment requirements under the circumstances set forth in such

laws, including as required by the Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or

other applicable laws, rules, regulations, or stock exchange listing standards, as may be in effect from time to time, and which

may operate to create additional rights for the Corporation with respect to awards and the recovery of amounts relating thereto.

By accepting awards under the Plan, the Participants consent to be bound by the terms of the Clawback Policy, if applicable, and

agree and acknowledge that they are obligated to cooperate with, and provide any and all assistance necessary to, the Corporation

in its efforts to recover or recoup any award, any gains or earnings related to any award, or any other amount paid under the Plan

or otherwise subject to clawback or recoupment pursuant to such laws, rules, regulations, stock exchange listing standards or Corporation

policy. Such cooperation and assistance shall include, but is not limited to, executing, completing and submitting any documentation

necessary to facilitate the recovery or recoupment by the Corporation from the Participant of any such amounts, including from

the Participant’s accounts or from any other compensation, to the extent permissible under Section 409A of the Code.

7. MISCELLANEOUS

7.1 Compliance with Laws and Policies.

The Corporation’s obligation

to make any payments or deliver (or cause to be delivered) any Shares hereunder is subject to compliance with Applicable Law. Each

Participant shall acknowledge and agree (and shall be conclusively deemed to have so acknowledged

and agreed by participating in

the Plan) that the Participant will, at all times, act in strict compliance with Applicable Law and all other laws and any policies

of the Corporation applicable to the Participant in connection with the Plan including, without limitation, furnishing to the Corporation

all information and undertakings as may be required to permit compliance with Applicable Law.

7.2 Withholdings.

So as to ensure that the Corporation

or an Affiliate, as applicable, will be able to comply with the applicable obligations under any federal, provincial, state or

local law relating to the withholding of tax or other required deductions, the Corporation or the Affiliate shall withhold or cause

to be withheld from any amount payable to a Participant, either under this Plan, or otherwise, such amount as may be necessary

to permit the Corporation or the Affiliate, as applicable, to so comply. Subject to Applicable Law, the Corporation and any Affiliate

may also satisfy any liability for any such withholding obligations, on such terms and conditions as the Board may determine in

its sole discretion, by (a) requiring such Participant to sell any Shares and retaining any amount payable which would otherwise

be provided or paid to such Participant in connection with any such sale, or (b) requiring, as a condition to the delivery of Shares

hereunder, that such Participant make such arrangements as the Board may require so that the Corporation and its Affiliates can

satisfy such withholding obligations, including requiring such Participant to remit an amount to the Corporation or an Affiliate

in advance, or reimburse the Corporation or any Affiliate for, any such withholding obligations.

7.3 No Right to Continued Employment.

Nothing in the Plan or in any Grant

Agreement entered into pursuant hereto shall confer upon any Participant the right to continue in the employ or service of the

Corporation or any Affiliate, to be entitled to any remuneration or benefits not set forth in the Plan or a Grant Agreement or

to interfere with or limit in any way the right of the Corporation or any Affiliate to terminate Participant’s employment

or service arrangement with the Corporation or any Affiliate.

7.4 No Additional Rights.

Neither the designation of an individual

as a Participant nor the Grant of any Options or Share Units to any Participant entitles any person to the Grant, or any additional

Grant, as the case may be, of any Options or Share Units. For greater certainty, the Board’s decision to approve a Grant

in any period shall not require the Board to approve a Grant to any Participant in any other period; nor shall the Board’s

decision with respect to the size or terms and conditions of a Grant in any period require it to approve a Grant of the same or

similar size or with the same or similar terms and conditions to any Participant in any other period. The Board shall not be precluded

from approving a Grant to any Participant solely because such Participant may have previously received a Grant under this Plan

or any other similar compensation arrangement of the Corporation or an Affiliate. No Eligible Person has any claim or right to

receive a Grant except as may be provided in a written employment or services agreement between an Eligible Person and the Corporation

or an Affiliate.

7.5 Amendment, Termination.

7.5.1 The Board may at any time and from time to time amend this Plan in whole or in part; provided,

however, that if an amendment to this Plan, for purposes of applicable Stock Exchange rules and except as permitted under

Section 5.1 of this Plan, (i) would materially increase the benefits accruing to Participants under this Plan, (ii) would materially

increase the number of securities which may be issued under this Plan, (iii) would materially modify the requirements for participation

in this Plan, or (iv) must otherwise be approved by the shareholders of the Corporation in order to comply with Applicable Law,

all as determined by the Board, then, such amendment will be subject to approval by the Corporation’s shareholders and will

not be effective unless and until such approval has been obtained.

7.5.2 Except in connection with a corporate transaction or event described in Section 5.1 of this Plan

or in connection with a Change in Control, the terms of outstanding Grants may not be amended to reduce the Exercise Price of outstanding

Options, or cancel outstanding “underwater” Options (including following a Participant’s voluntary surrender

of “underwater” Options) in exchange for cash, other awards or Options with an Exercise Price that is less than the

Exercise Price of the original Options without approval by the Corporation’s shareholders. This Section 7.5.2 is intended

to prohibit the repricing of “underwater” Options and will not be construed to prohibit the adjustments provided for

in Section 5.1 of this Plan. Notwithstanding any provision of this Plan to the contrary, this Section 7.5.2 may not be amended

without approval by the Corporation’s shareholders.

7.5.3 Subject to Section 7.5.2 of this Plan, the Board may amend the terms of any Grant theretofore granted

under this Plan prospectively or retroactively. Except for adjustments made pursuant to Section 5.1 of this Plan, no such amendment

will materially impair the rights of any Participant without his or her consent. The Board may, in its discretion, terminate this

Plan at any time. Termination of this Plan will not affect the rights of Participants or their successors under any awards outstanding

hereunder and not exercised in full on the date of termination.

7.6 Administration Costs.

The Corporation will be responsible

for all costs relating to the administration of the Plan.

7.7 Designation of Beneficiary.

Subject to the requirements of

Applicable Law, a Participant may designate a Beneficiary, in writing, to receive any benefits that are provided under the Plan

upon the death of such Participant. The Participant may, subject to Applicable Law, change such designation from time to time.

Such designation or change shall be in such form as may be prescribed by the Board from time to time. A Beneficiary designation

under this Section 7.7 and any subsequent changes thereto shall be filed with the chief legal officer of the Corporation.

7.8 Governing Law.

The Plan and any Grants pursuant

to the Plan shall be governed by and construed in accordance with the laws of the Province of British Columbia and the federal

laws of Canada applicable therein, and with respect to Participants who are US Taxpayers, with the Code and applicable federal

laws of the US. The Board may provide that any dispute to any Grant shall be presented and determined in such forum as the Board

may specify, including through binding arbitration. Any reference in the Plan, in any Grant Agreement issued pursuant to the Plan

or in any other agreement or document relating to the Plan to a provision of law or rule or regulation shall be deemed to include

any successor law, rule or regulation of similar effect or applicability. To the extent applicable, with respect to Participants

who are US Taxpayers, this Plan shall be interpreted in accordance with the requirements of Code Section 409A and the regulations,

notices, and other guidance of general applicability issued thereunder. To the extent that any provision of this Plan would prevent

any Option that was intended to qualify as an Incentive Stock Option from qualifying as such, that provision will be null and void

with respect to such Option, but will remain in effect for other Options and there will be no further effect on any provision of

this Plan. Notwithstanding anything in this Plan to the contrary, the provisions of Exhibit “A” to this Plan shall

apply with respect to Participants who are US Taxpayers.

7.9 Assignment.

The Plan shall inure to the benefit

of and be binding upon the Corporation, its successors and assigns.

7.10 Transferability.

7.10.1 Unless otherwise provided in the Plan or in the applicable Grant Agreement in accordance with Section

7.10.2, no Grant, and no rights or interests therein, shall or may be assigned, transferred, sold, exchanged, encumbered, pledged

or otherwise hypothecated or disposed of by a Participant other than by testamentary disposition by the Participant or the laws

of intestate succession. No such interest shall be subject to execution, attachment or similar legal process including without

limitation seizure for the payment of the Participant’s debts, judgments, alimony or separate maintenance. In no event will

any Grant under the Plan be transferred for value.

7.10.2 Notwithstanding the foregoing, with respect to Participants who are not US Taxpayers, the Board

may provide in the applicable Grant Agreement that a Grant is transferable or assignable (a) in the case of a transfer without

the payment of any consideration, to the Participant’s spouse, former spouse, children, stepchildren, grandchildren, parent,

stepparent, grandparent, sibling, persons having one of the foregoing types of relationship with a Participant due to adoption

and any entity in which these persons (or the Participant) own more than fifty percent (50%) of the voting interests and (b) to

an entity in which more than fifty percent (50%) voting interests are owned by these persons (or the Participant) in exchange for

an interest in that entity. Following any such transfer or assignment, the Grant shall remain subject to substantially the same

terms applicable to the Grant while held by the Participant to whom it was granted, as modified as the Board shall determine appropriate,

and, as a condition to such transfer, the transferee shall execute an agreement agreeing to be bound by such terms. Any purported

assignment or transfer that does not qualify under this Section 7.10.2 shall be void and unenforceable against the Corporation.

7.11 Substitute Awards.

7.11.1 Grants may be made under this Plan in substitution for or in conversion of, or in connection with

an assumption of, stock options, restricted share units, performance share units or other stock or stock-based awards held by awardees

of an entity engaging in a corporate acquisition or merger transaction with the Corporation or any Subsidiary. Any conversion,

substitution or assumption will be effective as of the close of the merger or acquisition, and, to the extent applicable, will

be conducted in a manner that complies with Code Section 409A or Section 7(1.4) of the Tax Act (if any such converted, substituted

or assumed stock option, restricted share unit, performance share unit or other stock or stock-based award is, or is intended to

be, subject to Section 7 of the Tax Act). The Grants so made may reflect the original terms of the awards being assumed or substituted

or converted for and need not comply with other specific terms of this Plan, and may account for Shares substituted for the securities

covered by the original awards and the number of shares subject to the original awards, as well as any exercise or purchase prices

applicable to the original awards, adjusted to account for differences in stock prices in connection with the transaction.

7.11.2 In the event that a company acquired by the Corporation or any Subsidiary or with which the Corporation

or any Subsidiary merges has shares available under a pre-existing plan previously approved by shareholders and not adopted in

contemplation of such acquisition or merger, the shares available for grant pursuant to the terms of such plan (as adjusted, to

the extent appropriate, to reflect such acquisition or merger) may be used for Grants made after such acquisition or merger under

this Plan; provided, however, that Grants using such available shares may not be made after the date awards

or grants could have been made under the terms of the pre-existing plan absent the acquisition or merger, and may only be made

to individuals who were not employees or directors of the Corporation or any Subsidiary prior to such acquisition or merger.

7.11.3 Any Shares that are issued or transferred by, or that are subject to any awards that are granted

by, or become obligations of, the Corporation under Sections 7.11.1 or 7.11.2 of this Plan will not reduce the Shares available

for issuance or transfer under this Plan or otherwise count against the limits contained in Section 4 of this Plan, except as otherwise

provided in this Plan. In addition, no Shares subject to an award that is granted by, or becomes an obligation of, the Corporation

under Sections 7.11.1 or 7.11.2 of this Plan, will be added to the aggregate limit contained in Section 4.1.1 of this Plan.

8. EFFECTIVE DATE AND TERM

8.1 The Plan was approved by the Board on September 29, 2017, as amended on September 24, 2020, as

amended on December 4, 2023, and as further amended on February 6, 2026, and by the Corporation’s shareholders on November

9, 2017, as amended on November 4, 2020, as amended on January 19, 2024, and as further amended on April 6, 2026 (the “Amended

Effective Date”). This Plan will remain in effect, unless sooner terminated as provided herein, until April 6, 2036,

at which time it will terminate. After this Plan is terminated, no Grants may be granted hereunder but Grants previously granted

will remain outstanding in accordance with their applicable terms and conditions and this Plan’s terms and conditions.

PART

II – OPTIONS

9. OPTIONS

9.1 The Corporation may, from time to time, make one or more Grants of Options to Eligible Persons

on such terms and conditions, consistent with the Plan, as the Board shall determine. In granting such Options, subject to the

provisions of the Plan, the Corporation shall specify,

(a) the maximum number of Shares which the Participant may purchase under the Options;

(b) the Exercise Price at which the Participant may purchase his or her Shares under the Options; and

Vesting period or periods within this period during which the Options or a portion thereof may be exercised by a Participant and

any other Vesting conditions (including Performance Conditions).

9.2 The Exercise Price for each Share subject to an Option shall be fixed by the Board but under no

circumstances (except with respect to Grants under Section 7.11 of this Plan) shall any Exercise Price be less than one hundred

percent (100%) of the Market Price on the Grant Date of such Option.

9.3 Subject to the provisions of the Plan and, upon prior approval of the Board, once an Option has

Vested and become exercisable a Participant may elect, in lieu of exercising such Option, to surrender such Option in exchange

for the issuance of Shares equal to the number determined by dividing (a) the difference between the Market Price (calculated as

at the date of settlement) and the Exercise Price of such Option by (b) the Market Price (calculated as at the date of settlement).

An Option may be surrendered and disposed of pursuant to this Section 9.3 from time to time by delivery to the Board at the head

office of the Corporation or such other place as may be specified by the Board, of (a) a written notice specifying that net settlement

will be effectuated for such Option and the number of Options to be exercised and (b) the payment of an amount for any tax withholding

or remittance obligations of the Participant or the Corporation arising under applicable law (or by entering into some other arrangement

acceptable to the Board). The Corporation will not be required, upon the net settlement of any Options pursuant to this Section

9.3, to issue fractions of Shares or to distribute certificates which evidence fractional Shares. In the event the number of Shares

to be issued upon the net settlement of an Option is a fraction, the Participant will receive the next lowest whole number of Shares

and will not receive any other form of compensation (cash or otherwise) for the fractional interest.

9.4 Unless otherwise designated by the Board in the applicable Grant Agreement and subject to Section

9.6, any Options included in a Grant shall expire on the tenth anniversary of the Grant Date (unless exercised or terminated earlier

in accordance with the terms of the Plan or the Grant Agreement).

9.5 Subject to the provisions of the Plan and the terms governing the granting of the Option, and subject

to payment or other satisfaction of all related withholding obligations in accordance with Section 7.2, Vested Options or a portion

thereof may be exercised from

time to time by delivery to the Corporation at its registered office of a notice in writing signed

by the Participant or the Participant’s legal personal representative, as the case may be, and addressed to the Corporation.

This notice shall state the intention of the Participant or the Participant’s legal personal representative to exercise the

said Options and the number of Shares in respect of which the Options are then being exercised and must be accompanied by payment

in full of the Exercise Price under the Options which are the subject of the exercise.

9.6 If the normal expiry date of any Option, other than an Incentive Stock Option, falls within any

Blackout Period or within ten (10) business days (being a day other than a Saturday, Sunday or other than a day when banks in Vancouver,

British Columbia are not generally open for business) following the end of any Blackout Period, then the expiry date of such Option

shall, without any further action, be extended to the date that is ten (10) business days following the end of such Blackout Period.

The foregoing extension applies to all Options whatever the Grant Date (other than Incentive Stock Options and other than an extension

beyond the original term of the Options in the case of Options held by a US Taxpayer).

9.7 Notwithstanding anything in this Plan to the contrary, for Options that are intended to qualify

as Incentive Stock Options and granted to a US Taxpayer, the following additional provisions will apply:

(a) Except as permitted by Code Section 424(a), or any successor provision, the Exercise Price per

Share shall not be less than one hundred percent (100%) of the per Share Market Price on the Grant Date of the Incentive Stock

Option; provided, however, that if a Participant owns shares possessing more than ten percent (10%) of the total combined voting

power of all classes of shares of the Corporation or of its Parent or any Subsidiary, the Exercise Price per Share of an Incentive

Stock Option granted to such Participant shall not be less than one hundred ten percent (110%) of the Market Price on the Grant

Date of the Incentive Stock Option.

(b) Except as permitted by Code Section 424(a), in no event shall any Incentive Stock Option be exercisable

during a term of more than ten (10) years after the Grant Date of the Incentive Stock Option; provided, however, that if a Participant

owns shares possessing more than ten percent (10%) of the total combined voting power of all classes of shares of the Corporation

or of its Parent or any Subsidiary, the Incentive Stock Option granted to such Participant shall be exercisable during a term of

not more than five (5) years after the Grant Date.

all legally required amounts necessary to satisfy any and all withholding and employment-related taxes attributable to the Participant’s

exercise of an Incentive Stock Option or a “disqualifying disposition” of Shares acquired through the exercise of an

Incentive Stock Option as defined in Code Section 421(b).

(d) Notwithstanding any other provision of the Plan, the aggregate fair market value (determined as

of the Grant Date of the Incentive Stock Option) of the Shares with respect to which Incentive Stock Options are exercisable for

the first time by a Participant during any calendar year under the Plan and any other “incentive

stock option” plans

of the Corporation or any Affiliate, shall not exceed US$100,000 (or such other amount as may be prescribed by the Code from time

to time); provided, however, that if the exercisability or Vesting of an Incentive Stock Option is accelerated as permitted under

the provisions of the Plan and such acceleration would result in a violation of the limit imposed by this Section 9.7(d), such

acceleration shall be of full force and effect but the number of Shares that exceed such limit shall be treated as having been

granted pursuant to an Option that is not an Incentive Stock Option; and provided, further, that the limits imposed by this Section

9.7(d) shall be applied to all outstanding Incentive Stock Options under the Plan and any other “incentive stock option”

plans of the Corporation or any Affiliate in chronological order according to the dates of grant.

(e) The Grant Agreement in respect of any Incentive Stock Option shall contain such other limitations

and restrictions upon the exercise of the Incentive Stock Option as the Board shall deem necessary to ensure that such Incentive

Stock Option will be considered an “incentive stock option” as defined in Code Section 422 or to conform to any change

therein.

9.8 Options granted under this Plan may not provide for any dividends or dividend equivalents thereon.

10. TERMINATION OF EMPLOYMENT AND DEATH OF A PARTICIPANT – OPTIONS

10.1 Outstanding Options held by a Participant (or the executors or administrators of such Participant’s

estate, any person or persons who acquire the right to exercise Options directly from the Participant by bequest or inheritance

or any other permitted transferee of the Participant under Section 11) as of the Participant’s Termination Date shall be

subject to the provisions of this Section 10, as applicable; except that, in all events, the period for exercise of Options shall

end no later than the last day of the maximum term thereof established under Sections 9.1(c), 9.6, 9.7(b) or 10.5, as the case

may be.

10.2 Except as otherwise provided in the applicable Grant Agreement or as may otherwise be required

to satisfy the minimum requirements of applicable employment or labour standards legislation, and subject to Section 10.1 and Section

10.6, in the case of a Participant’s Termination due to death, or in the case of the Participant’s Disability (i) those

of the Participant’s outstanding Options that have not become Vested prior to such date of death or Disability Date shall

be forfeited and cancelled as of such date, and the Participant waives any claim to damages in respect thereof whether related

or attributable to any contractual or common law termination entitlement or otherwise; and (ii) those of the Participant’s

outstanding Options that have become Vested prior to the Participant’s date of death or Disability Date shall continue to

be exercisable during the twelve (12) month period following the such date of death or Disability Date, as the case may be.

10.3 Except as otherwise provided in the applicable Grant Agreement or as may otherwise be required

to satisfy the minimum requirements of applicable employment or labour standards legislation, and subject to Section 10.1 and Section

10.6, in the case of a Participant’s Termination due to the termination of the Participant’s employment or termination

of the Participant’s contract for services by the Corporation or an Affiliate without Cause, (i) those of the Participant’s

outstanding Options that have not become Vested prior to the Participant’s Termination Date shall be forfeited and cancelled

as of

such date, and the Participant waives any claim to damages in respect thereof whether related or attributable to any contractual

or common law termination entitlement or otherwise and (ii) those of the Participant’s outstanding Options that have become

Vested prior to the Participant’s Termination shall continue to be exercisable during the one hundred and twenty (120) day

period following the Participant’s Termination Date.

10.4 Except as otherwise provided in the applicable Grant Agreement or as may otherwise be required

to satisfy the minimum requirements of applicable employment or labour standards legislation, and subject to Section 10.6, in the

case of a Participant’s Termination due to the Participant’s resignation (including the voluntary withdrawal of services

by a Participant who is not an employee under Applicable Law), (i) those of the Participant’s outstanding Options that have

not become Vested prior to the date on which the Participant provides notice to the Corporation of his or her resignation shall

be forfeited and cancelled as of such date, and the Participant waives any claim to damages in respect thereof whether related

or attributable to any contractual or common law termination entitlement or otherwise and (ii) those of the Participant’s

outstanding Options that have become Vested prior to the date on which the Participant provides notice to the Corporation of his

or her resignation shall continue to be exercisable during the ninety (90) day period following the Participant’s Termination

Date.

10.5 Notwithstanding the foregoing, with respect to any Option that is intended to be an Incentive Stock

Option, such Option shall not be exercisable for a period that is longer than (i) three (3) months from the date of the Participant’s

Termination for any reason other than death or disability (as defined in Code Section 22(e)), or (ii) twelve (12) months from the

Participant’s Termination due to disability (as defined in Code Section 22(e)) or death.

10.6 In addition to the Board’s rights under Section 3.1, the Board may, subject to Section 10.5,

at the time of a Participant’s Termination Date or Disability Date, extend the period for exercise of some or all of the

Participant’s Options, but not beyond the original expiry date, and/or allow for the continued Vesting of some or all of

the Participant’s Options during the period for exercise or a portion of it. Options that are not exercised prior to the

expiration of the exercise period, including any extended exercise period authorized pursuant to this Section 10.6, following a

Participant’s date of Termination or Disability Date, as the case may be, shall automatically expire on the last day of such

period.

10.7 Notwithstanding any other provision hereof or in any Grant Agreement and except may otherwise be

required to satisfy the minimum requirements of applicable employment or labour standards legislation, in the case of a Participant’s

termination of employment or termination of the Participant’s contract for services for Cause, any and all then outstanding

Options granted to the Participant, whether or not then exercisable, shall be immediately forfeited and cancelled, without any

consideration therefore, as of the Termination Date, and the Participant waives any claim to damages in respect thereof whether

related or attributable to any contractual or common law termination entitlement or otherwise.

10.8 For greater certainty, a Participant shall have no right to receive Shares or a cash payment, as

compensation, damages or otherwise, with respect to any Options that do not become Vested or that are not exercised before the

date on which the Options expire.

11. TRANSFERABILITY OF OPTIONS – US TAXPAYER

11.1 Notwithstanding Section 7.10, with respect to Participants who are US Taxpayers, no Incentive Stock

Option shall be transferable by the Participant, in whole or in part, other than by will or by the laws of descent and distribution.

If the Participant shall attempt any transfer of any Incentive Stock Option, such transfer shall be void and the Incentive Stock

Option shall terminate.

11.2 Further, with respect to Participants who are US Taxpayers, Options that are not Incentive Stock

Options shall be transferable, in whole or in part, by the Participant by will or by the laws of descent and distribution. In addition,

the Board may, in its sole discretion, permit the Participant to transfer any or all such Options to any “family member”

in accordance with Form S-8; provided, however, that the Participant cannot receive any consideration for the transfer and such

transferred Stock Option shall continue to be subject to the same terms and conditions as were applicable to such Option immediately

prior to its transfer.

PART

III – SHARE UNITS

12. DEFINITIONS

12.1 “Grant Value” means the dollar amount allocated to an Eligible Person in respect

of a Grant of Share Units as contemplated by Section 3.

12.2 “Share Unit Account” has the meaning set out in Section 14.1.

12.3 “Valuation Date” means the date as of which the Market Price is determined for

purposes of calculating the number of Share Units included in a Grant, which unless otherwise determined by the Board shall be

the Grant Date.

12.4 “Vesting Period” means, with respect to a Grant of Share Units, the period specified

by the Board, commencing on the Grant Date and ending on the last Vesting Date for such Share Units.

13. ELIGIBILITY AND GRANT DETERMINATION.

13.1 The Board may from time to time make one or more Grants of Share Units to Eligible Persons on such

terms and conditions, consistent with the Plan, as the Board shall determine, provided that, in determining the Eligible Persons

to whom Grants are to be made and the Grant Value for each Grant, the Board shall take into account the terms of any written employment

agreement or contract for services between an Eligible Person and the Corporation or any Affiliate and may take into account such

other factors as it shall determine in its sole and absolute discretion.

13.2 The Board shall determine the Grant Value and the Valuation Date (if not the Grant Date) for each

Grant under this Part III. Unless otherwise determined by the Board, the number of Share Units to be covered by each such Grant

shall be determined by dividing the Grant Value for such Grant by the Market Price of a Share as at the Valuation Date for such

Grant, rounded up to the next whole number.

13.3 Each Grant Agreement issued in respect of Share Units shall set forth, at a minimum, the type of

Share Units and Grant Date of the Grant evidenced thereby, the number of RSUs or PSUs subject to such Grant (which number, in the

case of PSUs, may be subject to

adjustment to reflect changes in compensation, job duties or other factors), the applicable Vesting

conditions, the applicable Vesting Period(s) and the treatment of the Grant upon Termination and may specify such other terms and

conditions consistent with the terms of the Plan as the Board shall determine or as shall be required under any other provision

of the Plan. The Board may include in a Grant Agreement under this Part III terms or conditions pertaining to confidentiality of

information relating to the Corporation’s operations or businesses which must be complied with by a Participant including

as a condition of the grant or Vesting of Share Units. Notwithstanding anything in this Plan or a Grant Agreement to the contrary,

nothing in this Plan or in a Grant Agreement prevents a Participant from providing, without prior notice to the Corporation, information

to governmental authorities regarding possible legal violations or otherwise testifying or participating in any investigation or

proceeding by any governmental authorities regarding possible legal violations, and for purpose of clarity a Participant is not

prohibited from providing information voluntarily to the Securities and Exchange Commission pursuant to Section 21F of the Securities

Exchange Act of 1934, as amended.

14. ACCOUNTS AND DIVIDEND EQUIVALENTS

14.1 Share Unit Account.

An account, called a “Share

Unit Account”, shall be maintained by the Corporation, or an Affiliate, as specified by the Board, for each Participant

who has received a Grant of Share Units and will be credited with such Grants of Share Units as are received by a Participant from

time to time pursuant to Section 13 and any dividend equivalent Share Units pursuant to Section 14.2. Share Units that fail to

Vest to a Participant and are forfeited pursuant to Section 15, or that are paid out to the Participant or his or her Beneficiary,

shall be cancelled and shall cease to be recorded in the Participant’s Share Unit Account as of the date on which such Share

Units are forfeited or cancelled under the Plan or are paid out, as the case may be. For greater certainty, where a Participant

is granted both RSUs and PSUs, such RSUs and PSUs shall be recorded separately in the Participant’s Share Unit Account.

14.2 Dividend Equivalent Share Units.

Except as otherwise provided in

the Grant Agreement relating to a Grant of RSUs or PSUs, if and when cash dividends (other than extraordinary or special dividends)

are paid with respect to Shares to shareholders of record as of a record date occurring during the period from the Grant Date under

the Grant Agreement to the date of settlement of the RSUs or PSUs granted thereunder, a number of dividend equivalent RSUs or PSUs,

as the case may be, shall be credited to the Share Unit Account of the Participant who is a party to such Grant Agreement. The

number of such additional RSUs or PSUs will be calculated by dividing the aggregate dividends or distributions that would have

been paid to such Participant if the RSUs or PSUs in the Participant’s Share Unit Account had been Shares by the Market Price

on the date on which the dividends or distributions were paid on the Shares. The additional RSUs or PSUs granted to a Participant

will be subject to the same terms and conditions, including Vesting and settlement terms, as the corresponding RSUs or PSUs, as

the case may be.

15. VESTING AND SETTLEMENT OF SHARE UNITS

15.1 Continued Employment.

Subject to this Section 15 and

the applicable Grant Agreement, Share Units subject to a Grant and dividend equivalent Share Units credited to the Participant’s

Share Unit Account in respect of such Share Units shall Vest in such proportion(s) and on such Vesting Date(s) as may be specified

in the Grant Agreement governing such Grant provided that the Participant is Employed or acting as a Director on the relevant Vesting

Date.

15.2 Settlement.

A Participant’s RSUs and

PSUs, adjusted in accordance with the applicable multiplier, if any, as set out in the Grant Agreement, and rounded down to the

nearest whole number of RSUs or PSUs, as the case may be, shall be settled, by a distribution as provided below to the Participant

or his or her Beneficiary, upon, or as soon as reasonably practicable following, the Vesting thereof in accordance with Section

15.1 or 15.6, as the case may be, subject to the terms of the applicable Grant Agreement. Except as otherwise provided in an applicable

Grant Agreement in compliance with Code Section 409A (to the extent applicable), in all events RSUs and PSUs will be settled on

or before the earlier of the ninetieth (90th) day following the Vesting Date and the date that is two and one half (2½)

months after the end of the year in which Vesting occurred. Settlement shall be made by the issuance of one Share for each RSU

or PSU then being settled, as specified in the applicable Grant Agreement, and subject to payment or other satisfaction of all

related withholding obligations in accordance with Section 7.2.

15.3 Postponed Settlement.

Except as otherwise determined

by the Board in compliance with Code Section 409A, if a Participant’s Share Units would, in the absence of this Section 15.3

be settled within a Blackout Period applicable to such Participant, such settlement shall be postponed until the Trading Day (for

the primary Stock Exchange, as determined under Section 1.3.23) following the date on which such Blackout Period ends (or as soon

as practicable thereafter).

15.4 Failure to Vest.

For greater certainty, except as

otherwise provided in the applicable Grant Agreement, a Participant shall have no right to receive Shares or a cash payment, as

compensation, damages or otherwise, with respect to any RSUs or PSUs that do not become Vested.

15.5 Resignation.

Except as otherwise provided in

the applicable Grant Agreement and Section 15.7 or as may otherwise be required to satisfy the minimum requirements of applicable

employment or labour standards legislation, in the event a Participant’s employment is Terminated as a result of the Participant’s

resignation, no Share Units that have not Vested prior to the date on which the Participant submits his or her resignation, including

dividend equivalent Share Units in respect of such Share Units, shall Vest and all such Share Units shall be forfeited immediately,

and the Participant waives any claim to damages in respect thereof whether related or attributable to any contractual or common

law termination entitlement or otherwise.

15.6 Termination of Employment without Cause; Death or Disability.

Except as otherwise provided in

the applicable Grant Agreement or as may otherwise be required to satisfy the minimum requirements of applicable employment or

labour standards legislation, in the case of a Participant’s Termination without Cause or due to death or Disability of a

Participant, all Share Units granted to the Participant that have Vested as at the Termination Date shall be paid to the Participant

or Participant’s estate, as applicable, in accordance with the settlement provisions herein. Any Share Units that have not

Vested as at the Termination Date will be immediately cancelled and forfeited to the Corporation and the Participant waives any

claim to damages in respect thereof whether related or attributable to any contractual or common law termination entitlement or

otherwise, provided that if any unvested Share Units are subject to Performance Conditions, then if a Performance Condition is,

in the Board’s discretion, capable of being partially performed, such unvested Share Units shall become Vested Share Units

as at the Termination Date on a pro rata basis to reflect the degree to which the vesting condition has been satisfied, as determined

by the Board (and in all cases except as otherwise provided in the applicable Grant Agreement).

15.7 Extension of Vesting.

The Board may, at the time of Termination

or a Disability Date, extend the period for Vesting of Share Units, but not beyond the original end of the applicable Vesting Period,

or accelerate the Vesting of Share Units. With respect to U.S. Taxpayers, any such modification shall be made in compliance with

Code Section 409A.

15.8 Termination of Employment for Cause.

Except as may otherwise be required

to satisfy the minimum requirements of applicable employment or labour standards legislation, in the event a Participant’s

employment is Terminated for Cause by the Corporation, no Share Units that have not Vested prior to the Participant’s Termination

Date, including dividend equivalent Share Units in respect of such Share Units, shall Vest and all such Share Units shall be forfeited

immediately, and the Participant waives any claim to damages in respect thereof whether related or attributable to any contractual

or common law termination entitlement or otherwise.

16. SHAREHOLDER RIGHTS

16.1 No Rights to Shares.

Share Units are not Shares and

a Grant of Share Units will not entitle a Participant to any shareholder rights, including, without limitation, voting rights,

dividend entitlement (except as provided in Section 14.2) or rights on liquidation until the allotment and issuance to the Participant

of a certificate or certificates in the name of the Participant or a statement of account representing the Shares to which such

Share Units relate.

Exhibit “A”

NioCorp Developments Ltd. Long Term

Incentive Plan

Special Provisions Applicable to

US Taxpayers

This Exhibit sets forth special provisions

of the NioCorp Developments Ltd. Long Term Incentive Plan (the “Plan”) that apply to Participants who are US Taxpayers.

This Exhibit shall apply to such Participants notwithstanding any other provisions of the Plan. Terms defined elsewhere in the

Plan and used herein shall have the meanings set forth in the Plan, as may be amended from time to time.

Definitions

“Eligible Person” means,

solely with respect to Options, a Director or an individual with respect to which the Corporation would be an eligible issuer of

“service recipient stock” for purposes of Section 409A of the Code who (i) meets the Form S-8 definition of “employee”

and (ii) by the nature of his or her position or job is, in the opinion of the Board, in a position to contribute to the success

of the Corporation; provided, however, that only persons who meet the definition of “employees” under Code Section

3401(c) shall be eligible to receive Incentive Stock Options.

“Good Reason” means,

except as otherwise provided in applicable Grant Agreement, the occurrence of any one or more of the following without a Participant’s

written consent:

(i) a material diminution in the Participant’s duties, responsibilities, or authority in effect

immediately prior to a Change in Control;

(ii) a material diminution in the aggregate value of base salary and bonus opportunity provided to the

Participant for services provided to the Corporation or an Affiliate;

(iii) the Corporation or an Affiliate relocating the Participant’s primary office to any place

other than the location at which the Participant reported for work on a regular basis immediately prior to a Change in Control

or a place within 50 miles of that location; or

(iv) Any other action or inaction by the Corporation constituting a material breach of an effective

employment arrangement or agreement with the Participant.

A Participant must notify the

Corporation of the Participant’s intention to invoke Termination for Good Reason within 90 days after the occurrence of such

event and provide the Corporation 30 days’ opportunity for cure, and the Participant must actually terminate the Participant’s

employment with the Corporation prior to the 365th day following such occurrence or such event shall not constitute Good Reason.

“Market Price” means,

solely with respect to the term “Exercise Price”, (a) if the Shares are listed on only one Stock Exchange, the closing

price per Share on such Stock Exchange on the Trading Day immediately preceding the Grant Date, or, if there are no sales on such

date, on the next preceding Trading Day on which a sale occurred; (b) if the Shares are listed on more than one Stock Exchange,

the fair market value as determined in accordance with paragraph (a) above for the primary Stock Exchange on which the Shares are

listed, as determined by the Board; and (c) if the Shares are not listed for trading on a Stock Exchange, a price which is determined

by the Board in good faith to be the fair market value

of the Shares in compliance with the Code Section 409A. The Board is authorized

to adopt another fair market value pricing method provided such method is stated in the applicable Grant Agreement and is in compliance

with the fair market value pricing rules set forth in Code Section 409A.

Section 409A

Notwithstanding anything in the Plan to

the contrary, unless the applicable Grant Agreement provides otherwise, settlement of Share Units will in all events occur within

the “short-term deferral” period determined under Treasury Regulation Section 1.409A-1(b)(4).

To the extent applicable, it is intended

that this Plan and any Grants made hereunder comply with or be exempt from the provisions of Section 409A of the Code, so that

the income inclusion provisions of Section 409A(a)(1) of the Code do not apply to the Participants. This Plan and any grants made

hereunder will be administered in a manner consistent with this intent. Any reference in this Plan to Section 409A of the Code

will also include any regulations or any other formal guidance promulgated with respect to such section by the U.S. Department

of the Treasury or the Internal Revenue Service.

Neither a Participant nor any of a Participant’s

creditors or beneficiaries will have the right to subject any deferred compensation (within the meaning of Section 409A of the

Code) payable under this Plan and Grants hereunder to any anticipation, alienation, sale, transfer, assignment, pledge, encumbrance,

attachment or garnishment. Except as permitted under Section 409A of the Code, any deferred compensation (within the meaning of

Section 409A of the Code) payable to a Participant or for a Participant’s benefit under this Plan and Grants hereunder may

not be reduced by, or offset against, any amount owed by a Participant to the Corporation or any of its Affiliates.

If, at the time of a Participant’s

separation from service (within the meaning of Section 409A of the Code), (a) the Participant will be a specified employee (within

the meaning of Section 409A of the Code and using the identification methodology selected by the Corporation from time to time)

and (b) the Corporation makes a good faith determination that an amount payable hereunder constitutes deferred compensation (within

the meaning of Section 409A of the Code) the payment of which is required to be delayed pursuant to the six-month delay rule set

forth in Section 409A of the Code in order to avoid taxes or penalties under Section 409A of the Code, then the Corporation will

not pay such amount on the otherwise scheduled payment date but will instead pay it, without interest, on the fifth business day

of the seventh month after such separation from service (or, if earlier, upon the Participant’s death).

Notwithstanding any provision of this Plan

and Grants hereunder to the contrary, in light of the uncertainty with respect to the proper application of Section 409A of the

Code, the Corporation reserves the right to make amendments to this Plan and Grants hereunder as the Corporation deems necessary

or desirable to avoid the imposition of taxes or penalties under Section 409A of the Code. In any case, a Participant will be solely

responsible and liable for the satisfaction of all taxes and penalties that may be imposed on a Participant or for a Participant’s

account in connection with this Plan and Grants hereunder (including any taxes and penalties under Section 409A of the Code), and

neither the Corporation nor any of its affiliates will have any obligation to indemnify or otherwise hold a Participant harmless

from any or all of such taxes or penalties.
