company incorporated under the laws of Canada, as rights agent



(the “Rights Agent”)



WHEREAS:



A.          The
Board of Directors of the Corporation, in the exercise of their fiduciary duties, have determined that it is advisable and in the
best interests of the Corporation to adopt a new shareholder rights plan to: (a) ensure, to the extent possible that all holders
of the Common Shares (as hereinafter defined) of the Corporation and the Board of Directors have adequate time to consider and
evaluate any unsolicited bid for the Common Shares; (b) provide the Board of Directors with adequate time to identify, develop
and negotiate value-enhancing alternatives, if considered appropriate, to any such unsolicited bid; (c) encourage the fair treatment
of the Corporation’s securityholders in connection with any Take-over Bid (as hereinafter defined) made for the Common Shares;
and (d), generally, to assist the Board of Directors in enhancing shareholder value (the “Rights Plan” or this
“Agreement”);



B.           In
connection with the implementation of the Rights Plan, the Board of Directors of the Corporation:



| | (a) | authorized the issuance of one Right in respect of each
Common Share outstanding as of 5:00 p.m. on the date of this Agreement (the “Record Time”) to each holder of
record of Common Shares as of the Record Time;
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | authorized the issuance of one Right in respect of each
Common Share issued after the Record Time and prior to the earlier of the Separation Time and the Expiration Time;

C.           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 in this Agreement; and



D.           The
Rights Agent has agreed to act on behalf of the Corporation in connection with the issuance, transfer, exchange and replacement

| | --- | ------------------------------------------------



| | (a) | The Corporation shall issue in accordance with the terms hereof one Right in respect of each Common Share outstanding at the
Record Time and one Right in respect of each Common Share that may be issued after the Record Time and prior to the earlier of
the Separation Time and the Expiration Time. Notwithstanding the foregoing, the Corporation shall issue one Right in respect of
each Common Share issued after the Record Time upon the exercise of rights after the Separation Time but prior to the Expiration
Time pursuant to the terms of the Convertible Securities outstanding at the Record Time.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | Certificates for Common Shares issued after the Record Time hereof but prior to the earlier of the Separation Time and the
Expiration Time shall evidence one Right for each Common Share represented thereby and shall have impressed, printed, or written
thereon or otherwise affixed thereto a legend in substantially the following form:
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



“Until the Separation Time
(as such term is defined in the Rights Agreement referred to below), this certificate also evidences and entitles the holder hereof
to certain Rights as set forth in a Shareholder Rights Plan Agreement, made as of April 27, 2012, (the “Rights Agreement”),
between Atna Resources Ltd. (the “Corporation”) and Computershare Trust Company of Canada, as Rights Agent,
the terms of which are hereby incorporated herein by reference and a copy of which is on file and may be inspected during normal
business hours at the principal executive offices of the Corporation. Under certain circumstances, as set forth in the Rights Agreement,
such Rights may be amended or redeemed, may expire, may become void, or may be evidenced by separate certificates and may no longer
be evidenced by this certificate. The Corporation will mail or arrange for the mailing of a copy of the Rights Agreement to the
holder of this certificate without charge as soon as practicable after the receipt of a written request therefor.”



Certificates representing Common Shares that are issued and
outstanding at the Record Time shall evidence one Right for each Common Share evidenced thereby notwithstanding the absence of
a legend in substantially the foregoing form until the earlier of the Separation Time and the Expiration Time.



| | 2.2 | Initial Exercise Price: Exercise of Rights: Detachment of Rights
| | --- | ----------------------------------------------------------------



| | (a) | Subject to adjustment as herein set forth, including subsections 3.1(a) and 3.1(b), each Right will entitle the holder thereof,
after the Separation Time and prior to the Expiration Time, to purchase, for the Exercise Price (or its U.S. Dollar Equivalent
on the Business Day immediately preceding the date of exercise of the Right), one Common Share. Notwithstanding any other provision
of this Agreement, any Rights held by the Corporation or any of its Subsidiaries shall be void.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



18

| | --- | ----------------------------------------------------------------------



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



| | (c) | From and after the Separation Time and prior to the Expiration Time, the Rights: (i) may be exercised and (ii) shall be registered
and transferable independent of the Common Shares. Promptly following the Separation Time, the Corporation shall prepare and the
Rights Agent shall mail to each holder of record of Common Shares as of the Separation Time (other than an Acquiring Person, any
other Person whose Rights are or become void pursuant to the provisions of subsection 3.1(b) hereof and, in respect of any
Rights Beneficially Owned by such Acquiring Person which are not held of record by such Acquiring Person, the holder of record
of such Rights), at such holder’s address as shown in the records of the Corporation (the Corporation hereby agreeing to
furnish copies of such records to the Rights Agent for this purpose):
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

completed and registered in such holder’s name, representing the number of Rights held by such holder at the Separation Time
and having such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Corporation
may deem appropriate and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any
applicable law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange or quotation
system on which the Rights may from time to time be listed or traded, or to conform to usage; and

substantially in the form attached to the Rights Certificate, appropriately completed and duly executed by the holder or his executors
or administrators or other personal representatives or his legal attorney duly appointed by instrument in writing in form and executed
in a manner reasonably satisfactory to the Rights Agent; and
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



19

payable in respect of any transfer involved in the issuance, transfer or delivery of Rights Certificates or the issuance, transfer
or delivery of certificates for Common Shares in a name other than that of the holder of the Rights being exercised.
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (e) | Upon receipt of a Rights Certificate accompanied by a duly completed and executed Election to Exercise, which does not indicate
that Rights evidenced by such Rights Certificate have become void pursuant to subsection 3.1(b) hereof, and payment as set
forth in subsection 2.2(d) above, the Rights Agent (unless otherwise instructed by the Corporation) shall thereupon promptly:
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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

will be issued by the Rights Agent to such holder or to such holder’s duly authorized assigns.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (g) | The Corporation covenants and agrees to:
| | --- | ----------------------------------------



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



20







| | (ii) | take all reasonable action as may be necessary on its part and within its power to comply with any applicable requirements
of the Business Corporations Act (British Columbia), the Securities Act (British Columbia) or comparable legislation
of each of the provinces and territories of Canada, and the rules and regulations thereunder, the 1933 Act and the 1934 Act, or
and any other applicable law, rule or regulation, in connection with the issuance and delivery of the Rights Certificates and of

| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | use its reasonable efforts to cause all Shares of the Corporation issued upon exercise of Rights to be listed upon the Toronto
Stock Exchange or such other stock exchange on which the Common Shares are listed at that time;
| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | pay, when due and payable, any and all applicable taxes (not including any taxes referable to the income or profit of the holder
or exercising Person or any liability of the Corporation to withhold tax) and charges which may be payable in respect of the original
issuance or delivery of the Rights Certificates or of any Shares of the Corporation issued upon the exercise of 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 securities in a name other than
that of the registered holder of the Rights being transferred or exercised;
| | ---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (v) | if necessary, 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; and
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (vi) | after the Separation Time, except as permitted by Section 5.1 or Section 5.4 hereof, 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
| | --- | -----------------------------------------------



Subject to Section 5.19, the Exercise Price, the number
and kind of Shares 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.



| | (a) | If the Corporation shall, at any time after the Record Time and prior to the Expiration Time:
| | --- | ---------------------------------------------------------------------------------------------



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



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



21







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



| | (iv) | issue any Common Shares (or other shares of capital or securities exchangeable for or convertible into or giving a right to
acquire Common Shares or other Shares) in respect of, in lieu of, or in exchange for, existing Common Shares in a reclassification
or redesignation of Common Shares, an amalgamation or statutory arrangement;
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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 in the manner set forth below. If an event occurs which would require an adjustment under both this Section 2.3
and subsection 3.1(a), the adjustment provided for in this Section 2.3 shall be in addition to, and shall be made prior
to, any adjustment required under subsection 3.1(a). If the Exercise Price and number of Rights are to be adjusted:



| | (x) | the Exercise Price in effect after such adjustment shall be equal to (a) the Exercise Price in effect immediately prior to
such adjustment, divided by (b) the number of Common Shares (or other Shares of capital) that a holder of one Common Share immediately
prior to such dividend, subdivision, change, consolidation or issuance would hold immediately thereafter as a result thereof (the
“Expansion Factor”) assuming the exercise of all such exchange or conversion rights, if any; and
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (y) | each Right held prior to such adjustment shall automatically become that number of Rights equal to the Expansion Factor, and
the adjusted number of Rights shall 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 whole share or security exchangeable for or convertible into a whole Share
of capital) shall have exactly one Right associated with it.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



If the securities purchasable upon exercise of Rights
are to be adjusted as provided above, the securities purchasable upon exercise of each Right after such adjustment shall be the
securities that a holder of the securities purchasable upon exercise of one Right immediately prior to such dividend, subdivision,
change, consolidation or issuance would hold immediately thereafter as a result thereof. To the extent that any such rights of
exchange, conversion or acquisition are not exercised prior to the expiration thereof, the Exercise Price shall be readjusted to
the Exercise Price which would then be in effect based upon the number of Common Shares (or securities convertible into or exchangeable
for Common Shares) actually issued upon the exercise of such rights. If, after the Record Time and prior to the Expiration Time,
the Corporation shall issue any shares of its authorized capital, other than Common Shares in a transaction of a type described
in the first sentence of this subsection 2.3(a), such shares 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 this Agreement
in order to effect such treatment.



22







| | (b) | If the Corporation shall, at any time after the Record Time and prior to the Separation Time, fix a record date for the making
of a distribution to all holders of Common Shares of rights, options or warrants entitling them (for a period expiring within 45
days after such record date) to subscribe for or purchase Common Shares (or securities convertible into or exchangeable for or
carrying a right to purchase or subscribe for Common Shares) at a price per Common Share (or, in the case of a security convertible
into or exchangeable for or carrying a right to purchase or subscribe for Common Shares, having a conversion, exchange or exercise
price (including the price required to be paid to purchase such convertible or exchangeable security or right) per share) that
is less than the Market Price per Common Share on such record date, the Exercise Price shall be adjusted. The Exercise Price in
effect after such record date shall equal the Exercise Price in effect immediately prior to such record date multiplied by a fraction,
of which:
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



| | (ii) | the denominator shall be the number of shares of Common Shares outstanding on such record date plus the number of additional
Common Shares to be offered for subscription or purchase (or into which the convertible or exchangeable securities or rights so
to be offered are initially convertible, exchangeable or exercisable). In case such subscription price may be paid in a form other
than cash, the value of such non-cash consideration shall be as determined by the Board of Directors, whose determination shall
be described in a certificate filed with the Rights Agent and shall be binding on the Rights Agent and the holders of the Rights.
Such adjustment shall be made whenever such a record date is fixed. To the extent that any such rights 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 then be in effect based
upon the number of Common Shares (or securities convertible into or exchangeable for Common Shares) actually issued upon the exercise
of such rights or warrants, as the case may be. For purposes of this Agreement, the granting of the right to purchase Common Shares
(whether previously unissued, treasury shares or otherwise) pursuant to any optional dividend reinvestment plan and/or any Common
Share purchase plan providing for the reinvestment of dividends payable on securities of the Corporation and/or employee stock
option, stock purchase or other employee benefit plan (so long as such right to purchase is in no case evidenced by the delivery
of rights or warrants) shall not be deemed to constitute an issue of rights, options or warrants by the Corporation; provided,
however, that, in the case of any dividend reinvestment plan, the right to purchase Common Shares is at a price per share of not
less than 90% of the then current market price per share (determined as provided in such plan) of the Common Shares.

| | (c) | If the Corporation shall, at any time after the Record Time and prior to the Separation Time, fix a record date for the making
of a distribution to all holders of Common Shares of evidences of indebtedness or assets (other than a Regular Periodic Cash Dividend
or a dividend paid in Common Shares) or rights, options or warrants (excluding those referred to in subsections 2.3(a) or
2.3(b)), the Exercise Price shall be adjusted as follows: the Exercise Price in effect after such record date shall, subject to
adjustment as provided in the penultimate sentence of subsection 2.3(b), equal the Exercise Price in effect immediately prior
to such record date less the fair market value (as determined by the Board of Directors, whose determination shall be described
in a statement filed with the Rights Agent) of the portion of the assets, evidences of indebtedness, rights, options or warrants
so to be distributed applicable to the securities purchasable upon exercise of one Right.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | Each adjustment made pursuant to this Section 2.3 shall be made as of:
| | --- | ----------------------------------------------------------------------



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



| | (ii) | the record date for the applicable dividend or distribution, in the case of an adjustment made pursuant to subsections 2.3(b)
or 2.3(c) above.
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------



| | (e) | Subject to the prior consent of the holders of Common Shares or Rights obtained in accordance with the provisions of subsections 5.4(b)
or (c) hereof, as applicable, if the Corporation shall, at any time after the Record Time and prior to the Expiration Time, issue
any Shares (other than Common Shares), or rights or warrants to subscribe for or purchase any such Shares, or securities convertible
into or exchangeable for any such Shares, in a transaction referred to in clause (a)(i) or (a)(iv) of this Section 2.3 and if the
Board of Directors determines that the adjustments contemplated by subsections 2.3(a), (b) and (d) above in connection with
such transaction will not appropriately protect the interests of the holders of Rights, the Board of Directors may determine what
other adjustments to the Exercise Price, number of Rights and/or securities purchasable upon exercise of Rights would be appropriate
and, notwithstanding such clauses, such adjustments (rather than the adjustments contemplated by subsections 2.3(a), (b) and
(d) above) shall be made and the Corporation and the Rights Agent shall amend this Agreement as appropriate to provide for such
adjustments.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



24







| | (f) | Anything herein to the contrary notwithstanding, no adjustment to the Exercise Price shall be required unless such adjustment
would require an increase or decrease of at least 1% in such Exercise Price; provided, however, that any adjustments which by reason
of this subsection 2.3(f) are not required to be made shall be carried forward and taken into account in any subsequent adjustment.
Each adjustment made pursuant to this Section 2.3 shall be calculated to the nearest cent or to the nearest one ten-thousandth
of a Common Share or Right, as the case may be.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (g) | All Rights 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 the Rights, all subject to further adjustment as provided herein.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (h) | Unless the Corporation shall have exercised its election as provided in subsection 2.3(i) hereof, upon each adjustment
of the Exercise Price as a result of the calculations made in subsections 2.3(b) or (c) above, each Right outstanding immediately
prior to the making of such adjustment shall thereafter evidence the right to purchase, at the adjusted Exercise Price, that number
of Common Shares (calculated to the nearest one ten-thousandth) obtained by:
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



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



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



25







| | (j) | Irrespective of any adjustment or change in the Exercise Price or the number of securities purchasable upon the exercise of
the Rights, the Rights Certificates theretofore and thereafter issued may continue to express the Exercise Price per share and
the number of securities so purchasable which were expressed in the initial Rights Certificates issued hereunder.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (k) | If, as a result of an adjustment made pursuant to Section 3.1, the holder of any Right thereafter exercised shall become
entitled to receive any securities other than Common Shares, thereafter the number of such other securities so receivable upon
exercise of any Right and the applicable Exercise Price thereof shall be subject to adjustment from time to time in a manner and
on terms as nearly equivalent as may be practicable to the provisions with respect to the Common Shares contained in the foregoing
subsections of this Section 2.3 and the provisions of this Agreement with respect to the Common Shares shall apply on like
terms to any such other securities.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



| | (m) | Notwithstanding anything 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
the Board of Directors determines advisable in order that any (i) subdivision or consolidation of the Common Shares, (ii) issuance
of any Common Shares at less than applicable Market Price, (iii) issuance of any Common Shares or securities that by their terms
are exchangeable for or convertible into or give a right to acquire Common Shares, (iv) stock dividends, or (v) issuance of rights,
options or warrants referred to in this Section 2.3, hereafter made by the Corporation to holders of its Common Shares, and
subject to applicable taxation laws, shall not be taxable to such shareholders.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



26







| | (n) | Whenever an adjustment to the Exercise Price or a change in the securities purchasable upon the exercise of Rights is made
pursuant to this Section 2.3, the Corporation shall promptly:
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



| | (ii) | file with the Rights Agent and with each transfer agent for the Common Shares, a copy of such certificate; and
| | ---- | --------------------------------------------------------------------------------------------------------------



| | (iii) | cause notice of the particulars of such adjustment or change to be delivered to the holders of the Rights.
| | ----- | ----------------------------------------------------------------------------------------------------------



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



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



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



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



| | (a) | The Rights Certificates shall be executed on behalf of the Corporation by any two of its Chairman, President and Chief Executive
Officer, its Chief Financial Officer or its Corporate Secretary. The signature of any of these officers on the Rights Certificates
may be manual or facsimile.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | Rights Certificates bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the
Corporation shall bind the Corporation, notwithstanding that such individuals or any of them have ceased to hold such offices prior
to the countersignature and delivery of such Rights Certificates.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | Promptly after the Corporation learns of the Separation Time, the Corporation shall notify the Rights Agent of such Separation
Time and shall deliver Rights Certificates executed by the Corporation to the Rights Agent for countersignature, and the Rights
Agent shall countersign (manually or by facsimile signature in a manner satisfactory to the Corporation) and deliver such Rights
Certificates (and a disclosure statement as described in Section 2.2(c)) 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 in the manner described above.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



27







| | (d) | Each Rights Certificate shall be dated the date of countersignature thereof.
| | --- | ----------------------------------------------------------------------------



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



| | (a) | The Corporation shall cause to be kept a register (the “Rights Register”) in which, subject to such reasonable
regulations as it may prescribe, the Corporation shall provide for the registration and transfer of Rights. The Rights Agent is
hereby appointed “Rights Registrar” for the purpose of maintaining the Rights Register for the Corporation and registering
Rights and transfers of Rights as herein provided. If the Rights Agent shall cease to be the Rights Registrar, the Rights Agent
shall have the right to examine the Rights Register at all reasonable times during normal business hours.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



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



| | (c) | Every Rights Certificate surrendered for registration of transfer or exchange shall have the form of assignment thereon duly
completed and 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 registered 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
by the holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and other
expenses (including the reasonable fees and expenses of the Rights Agent) in connection therewith.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | The Corporation shall not be required to register the transfer or exchange of any Rights after the Rights have been terminated
pursuant to the provisions of this Agreement.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 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 a new Rights Certificate evidencing the same number of Rights as did
the Rights Certificate so surrendered.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



28







| | (b) | If there shall be delivered to the Corporation and the Rights Agent prior to the Expiration Time (i) evidence to their satisfaction
of the destruction, loss or theft of any Rights Certificate and (ii) such security or indemnity as may be required by them to save
each of them and their respective 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.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | As a condition to the issuance of any new Rights Certificate under this Section 2.7, the Corporation may require the payment
of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses
(including the reasonable fees and expenses of the Rights Agent) in connection 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 an original additional 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
| | --- | ---------------------



Prior to due presentment of a Rights Certificate (or, prior
to the Separation Time, the associated Common Share certificate) for registration of transfer, the Corporation, the Rights Agent
and any agent of the Corporation or the Rights Agent may deem and treat the Person in whose name such Rights Certificate (or, prior
to the Separation Time, such Common Share certificate) is registered as the absolute owner thereof and of the Rights evidenced
thereby for all purposes whatsoever and the Company and the Rights Agent shall not be affected by any notice or knowledge to the
contrary except as required by statute or by order of a court of competent jurisdiction. As used in this Agreement, unless the
context otherwise requires, the term “holder” of any Rights means the registered holder of such Rights (or, prior to
the Separation Time, the associated Shares).



| | 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 Certificates 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 destroy all cancelled Rights Certificates
and 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 that:



29







| | (a) | prior to the Separation Time, each Right shall be transferable only together with, and shall be transferred by a transfer of,
the associated Common Share;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | after the Separation Time, the Rights Certificates shall be transferable only on the Rights Register, as provided herein;
| | --- | -------------------------------------------------------------------------------------------------------------------------



| | (c) | prior to due presentment of a Rights Certificate (or, prior to the Separation Time, the associated Common Share certificate)
for registration of transfer, the Corporation, the Rights Agent and any agent of the Corporation or the Rights Agent may deem and
treat the Person in whose name the Rights Certificate (or, prior to the Separation Time, the associated Common Share certificate)
is registered as the absolute owner thereof and of the Rights evidenced thereby (notwithstanding any notations of ownership or
writing on such Rights Certificate or the associated Common Share certificate made by anyone other than the 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;
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | such holder has waived all rights to receive any fractional Right or fractional Share upon exercise of a Right;
| | --- | ---------------------------------------------------------------------------------------------------------------



| | (e) | such holder is otherwise 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;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (f) | this Agreement may be supplemented or amended from time to time pursuant and subject to Section 5.4 and the last sentence of
the penultimate paragraph of subsection 2.3(a) hereof upon the sole authority of the Board of Directors without the approval
of any holder of Rights; and
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (g) | 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 any preliminary or permanent injunction or other order, decree or ruling 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.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3. | ADJUSTMENTS TO THE RIGHTS IN THE EVENT OF CERTAIN TRANSACTIONS
| | -- | --------------------------------------------------------------



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



| | (a) | Subject to the provisions of Sections 2.2, 3.1(b) and 5.1 hereof and except as provided below, if prior to the Expiration
Time a Flip-in Event shall occur, each Right shall thereafter constitute, effective at the Close of Business on the tenth Business
Day after the relevant Stock Acquisition Date or such longer period as may be required to satisfy the requirements of applicable
securities laws, including the 1933 Act and the 1934 Act, the right to purchase from the Corporation, upon exercise thereof in
accordance with the terms hereof, that number of Common Shares of the Corporation 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
hereof in the event that, after such date of consummation or occurrence, an event of a type analogous to any of the events described
in Section 2.3 hereof shall have occurred with respect to such Common Shares).
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



30







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



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



| | (ii) | a direct or indirect transferee of, or other successor in title to, such Rights (a “Transferee”), who becomes
a Transferee concurrently with or subsequent to the Acquiring Person becoming an Acquiring Person, in a transfer, whether or not
for consideration, that the Board of Directors has determined is part of a plan, understanding or scheme of an Acquiring Person
(or an Affiliate or Associate of an Acquiring Person or any Person acting jointly or in concert with an Acquiring Person or an
Affiliate or Associate of an Acquiring Person) that has the purpose or effect of avoiding the provisions of this subsection 3.1(b)
applicable in the circumstances contemplated in clause (i) hereof;
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



shall thereupon become and be null and void and any
holder of such Rights (including any Transferee) shall thereafter have no 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, or any Co-Rights Agent, as hereinafter defined, upon exercise or for registration of transfer or exchange
which does not contain the necessary certifications set forth in the Rights Certificate establishing that such Rights are not void
under this subsection 3.1(b) shall be deemed to be an Acquiring Person for the purposes of this subsection 3.1(b) and
such rights shall be null and void.



| | (c) | Any Rights Certificate that represents Rights Beneficially Owned by a Person described in either clauses (i) or (ii) of subsection 3.1(b)
hereof or transferred to any nominee of any such Person, and any Rights Certificate issued upon the transfer, exchange or replacement
of any other Rights Certificate referred to in this sentence shall contain and 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 Rights Agreement) or was acting jointly or in concert with any of them. This Rights Certificate and the Rights represented
hereby shall become void in the circumstances specified in subsection 3.1(b) of the Rights Agreement.”



31







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
be required to impose such legend only if instructed to do so by the Corporation or if a holder fails to certify upon transfer
or exchange in the space provided on the Rights Certificate that such holder is not an Acquiring Person or an Affiliate or Associate
thereof or acting jointly or in concert with any of them. The issuance of a Rights Certificate without the legend referred to in
this subsection shall be of no effect on the provisions of this subsection.



| | 4. | 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 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 one or more co-rights agents (each, a “Co-Rights Agent”) as it may deem necessary or desirable subject
to the approval of the Rights Agent, which approval shall not be unreasonably withheld. In such event, the respective duties of
the Rights Agent and any Co-Rights Agent shall be as the Corporation may determine with the written approval of the 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 incurred in the administration
and execution of this Agreement and the exercise and performance of its duties hereunder. The Corporation also agrees to indemnify
the Rights Agent, its officers, directors, employees and agents for, and to hold them harmless against, any loss, liability, or
expense, incurred without gross negligence, bad faith or wilful misconduct on the part of the Rights Agent, its officers, directors,
employees or agents, for anything done or omitted by them in connection with the acceptance and performance of this Agreement,
including legal costs and expenses, which right to indemnification shall survive the termination of this Agreement or the resignation
or removal of the Rights Agent.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | The Rights Agent shall be protected from, and shall incur no liability for or in respect of, any action taken, suffered or
omitted by it in connection with its performance 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, opinion, statement or other paper or document reasonably believed by it in good
faith to be genuine and to be signed, executed and, where necessary, verified or acknowledged, by the proper Person or Persons.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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

any body corporate succeeding to the securityholder services business of the Rights Agent or any successor Rights Agent shall be

of any of the parties hereto, provided that such body corporate would be eligible for appointment as a successor Rights Agent under
the provisions of Section 4.4 hereof.

in all such cases, such Rights Certificates shall 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.

| | 4.3 | Duties of Rights Agent
| | --- | ----------------------



The Rights Agent undertakes the duties and obligations imposed
by this Agreement upon the following terms and conditions, by all of which the Corporation 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. The Corporation shall reimburse the Rights Agent for all reasonable legal
fees and disbursements incurred in connection with this Section 4.3(a).
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (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 or refraining from taking 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 an individual reasonably believed by the Rights Agent to be
the Chairman, the Chief Executive Officer, the Chief Financial Officer or any Vice-President and by the Secretary or any Assistant
Secretary of the Corporation and delivered to the Rights Agent; and such certificate shall be full authorization to the Rights
Agent for any action taken, omitted or suffered in good faith by it under the provisions of this Agreement in reliance upon such
certificate.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



33







| | (c) | The Rights Agent shall be liable hereunder only for its own gross negligence, bad faith or wilful misconduct and that of its
officers, directors, employees and agents.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | The Rights Agent shall 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 Shares or the Rights Certificates (except its countersignature thereof) or be required to verify the
same, but all such statements and recitals are and will be deemed to have been made by the Corporation only.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (e) | The Rights Agent shall 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 Share certificate or Rights Certificate (except its countersignature thereof); nor will it be responsible for any breach
by the Corporation of any covenant or condition contained in this Agreement or in any Rights Certificate; nor will it be responsible
for any change in the exercisability of the Rights (including the Rights becoming void pursuant to subsection 3.1(b) hereof)
or any adjustment required under the provisions of Section 2.3 hereof or responsible for the manner, method or amount of any
such adjustment or the ascertaining of the existence of facts that would require any such adjustment (except with respect to the
exercise of Rights after receipt of the certificate contemplated by Section 2.3 hereof describing any such adjustment); nor
will it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any Shares
to be issued pursuant to this Agreement or any Rights or as to whether any Shares shall, when issued, be duly and validly authorized,
executed, issued and delivered and be 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 to rely upon and directed to accept written instructions (including by electronic mail)
with respect to the performance of its duties hereunder from any Person reasonably believed by the Rights Agent to be the Chairman,
the Chief Executive Officer, the Chief Financial Officer or any Vice-President or the Secretary or any Assistant Secretary of the
Corporation, and to apply to such Persons for advice or instructions in connection with its duties, and it shall not be liable
for any action taken, omitted or suffered by it in good faith in accordance with instructions of any such Person.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



34







| | (h) | The Rights Agent and any shareholder, director, officer or employee of the Rights Agent may buy, sell or deal in 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 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 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 shall not be answerable or accountable for any act, omission,
default, neglect or misconduct of any such attorneys or agents or for any loss to the Corporation resulting from any such act,
omission, default, neglect or misconduct, provided reasonable care was exercised in good faith 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 upon 60 days’ notice (or such lesser notice as is acceptable to the Corporation) in writing delivered
or mailed to the Corporation and to each transfer agent of Common Shares by first class mail, and mailed or delivered to the holders
of the Rights in accordance with Section 5.9 hereof. The Corporation may remove the Rights Agent upon 30 days’ notice
in writing, mailed or delivered to the Rights Agent and to each transfer agent of the Common Shares by first class mail, and mailed
to the holders of the Rights in accordance with Section 5.9 hereof. If the Rights Agent should resign or be removed or otherwise
become incapable of acting, the Corporation shall appoint a successor to the Rights Agent. If the Corporation fails to make such
appointment within a period of 30 days after such removal or after it has been notified in writing of such resignation or incapacity
by the resigning or incapacitated Rights Agent or by the holder of any Rights (which holder shall, with such notice, submit such
holder’s Rights Certificate for inspection by the Corporation), then the Rights Agent or the holder of any Rights 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 body corporate incorporated under the laws of
Canada or a province thereof authorized to carry on the business of a trust company in the Province of British Columbia. After
appointment, the successor Rights Agent shall be vested with the same powers, rights, duties and responsibilities as if it had
been originally named as Rights Agent without further act or deed; but the predecessor Rights Agent, upon receipt of all fees and
expenses outstanding to the predecessor Rights Agent by the Corporation, shall deliver and transfer to the successor Rights Agent
any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary
for the purpose. Not later than the effective date of any such appointment, the Corporation shall 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. Failure to give any notice provided for in this Section 4.4, however, or any defect therein, shall not affect
the legality or validity of the resignation or removal of the Rights Agent or the appointment of the successor Rights Agent, as
the case may be. Following the resignation of the Rights Agent and until the appointment of a successor Rights Agent, the Corporation
shall be entitled to act in the capacity of the Rights Agent under this Agreement.



35







| | 4.5 | 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 whatsoever, the Rights Agent reasonably
determines that such an act might cause it to be in non-compliance with any applicable anti-money laundering or anti-terrorist
legislation, regulation or guideline. Further, should the Rights Agent reasonably determine at any time that its acting under this
Agreement has resulted in it being in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation
or guideline, then it shall have the right to resign on 10 days’ 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.



| | 4.6 | Fiduciary Duties of the Directors
| | --- | ---------------------------------



Nothing contained herein shall be construed to suggest or imply
that the Board of Directors shall not be entitled to recommend that holders of the Voting Shares and/or Convertible Securities
reject or accept any Take-over Bid or take any other action including the commencement, prosecution, defence or settlement of any
litigation and the solicitation of additional or alternative Take-over Bids or other proposals to shareholders that the Board of
Directors believes is necessary or appropriate in the exercise of its fiduciary duties.



| | 5. | MISCELLANEOUS
| | -- | -------------



| | 5.1 | Redemption and Waiver
| | --- | ---------------------



The Corporation shall give prompt written notice to the Rights
Agent of any waiver of the application of Section 3.1 made by the Board of Directors acting in good faith under this Section 5.1.
In addition,



| | (a) | Subject to the prior consent of the holders of Voting Shares or Rights obtained as set forth in Section 5.4(b) or Section 5.4(c)
hereof, the Board of Directors, acting in good faith, 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, may 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 to the Exercise Price provided for in Section 2.3 hereof, if an event analogous to any of the events described
in Section 2.3 hereof, shall have occurred (such redemption price being herein referred to as the “Redemption Price”).
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | Subject to the prior consent of the holders of Voting Shares or Rights obtained as set forth in Section 5.4(b) or Section 5.4(c)
hereof, the Board of Directors, acting in good faith, may, at any time prior to the occurrence of a Flip-in Event, waive the application
of Section 3.1 hereof, to such Flip-in Event, if such Flip-in Event would occur by reason of an acquisition of Common Shares
other than pursuant to a Take-over Bid made by means of a Take-over Bid circular to all holders of record of Common Shares and
other than in the circumstances set forth in subsection 5.1(d) hereof.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



36







| | (c) | 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
paragraph, upon written notice to the Rights Agent, the Board of Directors may waive the application of Section 3.1 hereof,
to such Flip-in Event but only if such Flip-in Event occurs as a result of a Take-over Bid made by way of a Take-over Bid circular
sent to all holders of record of Common Shares; provided, however, that if the Board of Directors waives the application of Section 3.1
hereof, to a particular Flip-in Event, the Board of Directors shall be deemed to have waived the application of Section 3.1
hereof, to any other Flip-in Event occurring by reason of any Take-over Bid which is made by means of a Take-over Bid circular
to all holders of record of Common Shares (i) prior to the granting of such a waiver, or (ii) thereafter and 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) | The Board of Directors, acting in good faith, may waive the application of Section 3.1 to a Flip-in Event provided that
the following conditions are satisfied:
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | the Board of Directors has determined that the Acquiring Person became an Acquiring Person by inadvertence and without any
intention to become, or knowledge that it would become, an Acquiring Person; and
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | such Acquiring Person has reduced its Beneficial Ownership of Common Shares or has entered into a contractual arrangement with
the Corporation, acceptable to the Board of Directors, to do so within thirty (30) days of the date on which such contractual arrangement
is entered into, such that at the time of the waiver pursuant to this subsection 5.1(d), it is no longer an Acquiring Person.
| | ---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



If such Person remains an Acquiring Person following
such period, such date shall be deemed to be the date of occurrence of a further Share Acquisition Date and Section 3.1 shall apply
thereto.



| | (e) | If a Person acquires, pursuant to a Permitted Bid or a Competing Permitted Bid or pursuant to an Exempt Acquisition occurring
under subsection 5.1(c) hereof, outstanding Common Shares, other than Common Shares Beneficially Owned at the date of such
Permitted Bid, Competing Permitted Bid or Exempt Acquisition by such Person, the Board of Directors of the Corporation shall, notwithstanding
the provisions of subsection 5.1(a) hereof, immediately upon the consummation of such acquisition and without further formality
be deemed to have elected to redeem, and shall redeem, the Rights at the Redemption Price.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (f) | If the Board of Directors has elected to or is deemed to have elected to redeem the Rights and, in circumstances where subsection 5.1(a)
is applicable, (i) 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, and (ii) no further Rights shall thereafter
be issued.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (g) | Within 10 Business Days of the Board of Directors electing or having been deemed to have elected to redeem the Rights, the
Corporation shall give notice of redemption to the holders of record of the then outstanding Rights by mailing such notice to each
such holder at its last address as it appears upon the Rights Register of the Rights Agent, or, prior to the Separation Time, on
the share register maintained by the Corporation’s transfer agent. Each such notice of redemption shall state the method
by which the payment of the Redemption Price shall be made.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



37







| | (h) | Where a Take-over Bid that is not a Permitted Bid or Competing Permitted Bid expires, 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 of the outstanding Rights at the Redemption Price.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



| | (j) | Upon the Rights being redeemed pursuant to Section 5.1(h) above, all the provisions of this Agreement shall continue to
apply as if the Separation Time had not occurred and Rights Certificates representing the number of Rights held by each holder
of record of Common Shares as of the Separation Time had not been mailed to each such holder and for all purposes of this Agreement,
the Separation Time shall be deemed not to have occurred and the rights shall remain attached to the outstanding Common Shares,
subject to and in accordance with the provisions of this Agreement.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

No Person shall have any rights pursuant to or arising out of
this Agreement or in respect of any Right after the Expiration Time, except as provided in Section 4.1 hereof.

Notwithstanding any of the provisions of this Agreement or of
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 Shares purchasable
upon exercise of Rights made in accordance with the provisions of this Agreement.



| | 5.4 | Supplements and Amendments

Voting Shares, any supplements or amendments to this Agreement: (i) specifically contemplated in subsection 2.10(f); (ii)
to correct any clerical or typographical error; or (iii) which are required to maintain the validity and effectiveness of the Agreement
as a result of any change in any applicable laws, rules or regulatory requirements. The Corporation may, prior to the date of any
shareholders meeting referred to in Section 5.17, supplement, amend, vary or delete any of the provisions of this Agreement
without the approval of any holder of Rights or Common Shares, where the Board of Directors deems in good faith that such action
is necessary or desirable. Notwithstanding anything in this Section 5.4 to the contrary, no such supplement or amendment shall
be made to the provisions of Article 4 except with the written concurrence of the Rights Agent to such supplement or amendment.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Such consent shall be deemed to have been given if provided by the holders of Voting Shares at a special meeting of the holders
of Voting Shares called and held in compliance with applicable laws, rules and regulatory requirements and the requirements in
the articles and by-laws of the Corporation. Subject to compliance with any requirements imposed by the foregoing, consent shall

with applicable laws, rules and regulatory requirements and, to the extent possible, with the requirements in the articles and
by-laws of the Corporation applicable to meetings of holders of Common Shares, applied mutatis mutandis. Subject to compliance
with any requirements imposed by the foregoing, consent shall be deemed to have been given if the proposed amendment, variation

| | (i) | if made before the Separation Time, be submitted to the holders of Common Shares at the next meeting of shareholders and the
shareholders may, by the majority referred to in subsection 5.4(b) above hereto, confirm or reject such amendment; and
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | if made after the Separation Time, be submitted to the holders of Rights at a meeting to be called in accordance with the provisions

39







Any such amendment shall, unless the Board of Directors
otherwise stipulates, be effective from the date of the resolution of the Board of Directors adopting such amendment, until it
is confirmed or rejected or until it ceases to be effective (as described in the next sentence) and, where such amendment is confirmed,
it continues in effect in the form so confirmed. If such amendment is rejected by the shareholders of the Corporation or the holders
of Rights or is not submitted to the shareholders of the Corporation or holders of Rights as required, then such amendment shall
cease to be effective from and after the termination of the meeting at which it was rejected or to which it should have been but
was not submitted or if such a meeting of the holders of Rights is not called within a period of 90 days of the making of any such
amendment, at the end of such period, and no subsequent resolution of the Board of Directors to amend this Agreement to substantially
the same effect shall be effective until confirmed by the shareholders of the Corporation or holders of Rights, as the case may
be.



| | 5.5 | Fractional Rights and Fractional Common Shares
| | --- | ----------------------------------------------



| | (a) | The Corporation shall not be required to issue fractions of Rights or to distribute Rights Certificates which evidence fractional
Rights. In lieu of issuing fractional Rights, the Corporation shall pay to the registered holders of the Right Certificates, at
the time such fractional Rights would otherwise be issuable, an amount in cash equal to the same 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. The Rights Agent shall have
no obligation to make any payments in lieu of fractional Rights unless the Corporation shall have provided the Rights Agent with
the necessary funds to pay in full all amounts payable in accordance with Section 2.2(e).
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | The Corporation shall not be required to issue fractions of Common Shares upon exercise of the Rights or to distribute certificates
which evidence fractional Common Shares or other securities. In lieu of issuing fractional Common Shares or other securities, the
Corporation shall pay to the registered holders of Rights Certificates at the time such Rights are exercised as herein provided,
an amount in cash equal to the same fraction of the Market Price of one Common Share that the fraction of a Common Share that would
otherwise be issuable upon the exercise of such Right is of a whole Common Share. The Rights Agent shall have no obligation to
make any payments in lieu of fractional Common Shares unless the Corporation shall have provided the Rights Agent with the necessary
funds to pay in full all amounts payable in accordance with Section 2.2(e).
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 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 registered
holders of the Rights, and any registered holder of any Rights, without the consent of the Rights Agent or of the registered 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, or otherwise
act in respect of, such holder’s right to exercise such holder’s Rights in the manner provided in such holder’s
Rights Certificate and in this Agreement. Without limiting the foregoing or any remedies available to the holders of Rights, it
is specifically acknowledged that the holders of Rights would not have an adequate remedy at law for any breach of this Agreement
and will be entitled to specific performance of the obligations under, and injunctive relief against actual or threatened violations
of the obligations of any Person subject to this Agreement.

| | 5.7 | Holder of Rights Not Deemed a Shareholder
| | --- | -----------------------------------------



No holder, as such, of any Rights shall be entitled to vote
other than pursuant to Sections 5.4 and 5.18 hereof, receive dividends or be deemed for any purpose the holder of Common Shares
or any other securities, which may at any time be issuable on the exercise of such Rights, nor shall anything contained herein
or in any Rights Certificate be construed to confer upon the holder of any Rights, 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 Section 5.8 hereof), or to receive dividends or subscription rights, or otherwise, until such Rights
shall have been exercised in accordance with the provisions hereof.



| | 5.8 | Notice of Proposed Actions

be so given within 10 Business Days after the occurrence of a change to the Rights and not less than 20 Business Days prior to
the date of taking such proposed action by the Corporation.

| | 5.12 | Benefits of this Agreement
| | ---- | --------------------------



Nothing in this Agreement shall be construed to give to any
Person other than the Corporation, the Rights Agent and the holders of the Rights any legal or equitable right, remedy or claim
under this Agreement; but this Agreement shall be for the sole and exclusive benefit of the Corporation, the Rights Agent and the
holders of the Rights.



| | 5.13 | Governing Law
| | ---- | -------------



This Agreement and each Right issued hereunder shall be deemed
to be a contract made under the laws of the Province of British Columbia and for all purposes shall be governed by and construed
in accordance with the laws of such Province applicable to contracts to be made and performed entirely within such Province.



| | 5.14 | Counterparts

This Agreement may be executed in any number of counterparts
and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute
but one and the same instrument.



| | 5.15 | Severability
| | ---- | ------------



If any term or provision hereof or the application thereof to
any circumstance shall, in any jurisdiction and to any extent, be invalid or unenforceable, such term or provision shall be ineffective
as to such jurisdiction to the extent of such invalidity or unenforceability without invalidating or rendering unenforceable the
remaining terms and provisions hereof or the application of such term or provision to circumstances other than those as to which
it is held invalid or unenforceable.



| | 5.16 | Determinations and Actions by the Board of Directors
| | ---- | ----------------------------------------------------



All actions, calculations and determinations (including all
omissions with respect to the foregoing) which are done or made by the Board of Directors, in good faith, shall not subject the
Board of Directors to any liability to the holders of the Rights.



| | 5.17 | Effective Date
| | ---- | --------------



This Agreement is effective in accordance with its terms from
the date hereof; provided that unless confirmed by ordinary resolution passed by a majority of the votes cast by Independent Shareholders
present in person or voting by proxy and who vote in respect of confirmation of this Agreement (subject to any additional requirements
relating to such vote prescribed by a stock exchange on which the Common Shares are listed) at a meeting of shareholders of the
Corporation to be held not later than July 31, 2012 this Agreement shall be of no further force or effect and all Rights issued
hereunder shall be void from the first to occur of: (i) the termination of such meeting; and (ii) the Close of Business (Vancouver

43







This Agreement must be reconfirmed by a resolution passed by
a majority of the votes cast by Independent Shareholders (subject to any additional requirements related to such vote prescribed
by a stock exchange on which the Common Shares are then listed) at the annual shareholder meeting of the corporation to be held
in 2015 and at every third annual meeting of the Corporation thereafter.  If this Agreement is not so reconfirmed or is not
presented for reconfirmation at such annual meeting, this Agreement and all outstanding Rights shall terminate and be void and
of no further force and effect on and from the date of termination of such annual meeting; provided that, such termination shall
not occur if a Flip-in Event has occurred (other than a Flip-in Event which has been waived pursuant to Section 5.1 hereof), prior
to the date upon which this Agreement would otherwise terminate pursuant to this Section 5.17.



| | 5.18 | Approval of Holders of Rights
| | ---- | -----------------------------



If, after the Separation Time, the approval of holders of Rights
is required in respect of a supplement or amendment to this Agreement made pursuant to Section 5.4 hereof, the Board of Directors
shall, within 31 days after the implementation of any such supplement or amendment, call a special meeting of the holders of Rights
to consider and, if thought fit, to pass a resolution approving the supplement or amendment, and such supplement or amendment shall
be deemed to have been approved if such resolution receives the affirmative vote of a majority of the votes cast by holders of
Rights represented at the meeting in person or by proxy excluding any Rights which are then void pursuant to the provisions of
subsection 3.1(b) hereof. In respect of any such meeting required to be held:



| | (i) | the Board of Directors shall fix a date for the meeting, which date shall be as soon as practicable after the implementation
of any supplement or amendment requiring approval, but not more than 110 days thereafter;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | the Board of Directors of the Corporation shall fix a record date for determining the holders of Rights entitled to receive
notice of such meeting in a manner analogous to the procedures set out in National Instrument 54-101 of the Canadian Securities
Administrators (as such policy may be amended or replaced from time to time, and as required in order to conform to the requirements
of any applicable securities legislation or policy) and the rules of any stock exchange on which the Common Shares are then listed,
and the articles and by-laws of the Corporation; and
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | each Right shall be entitled to one vote at such meeting and, in all other respects, the rules applicable to meetings of shareholders
set forth in the articles and by-laws of the Corporation shall apply in respect of such meeting of holders of Rights, mutatis mutandis.

| | 5.19 | Declaration as to Non-Canadian and Non-United States Holders
| | ---- | ------------------------------------------------------------



If, upon the advice of outside counsel, any action or event
contemplated by this Agreement would require compliance with the securities laws or comparable legislation of a jurisdiction outside
of Canada and the United States of America, the Board of Directors acting in good faith may take such actions as it may deem appropriate
to ensure that such compliance is not required, including without limitation establishing procedures for the issuance to a Canadian
resident Fiduciary of Rights or securities issuable on exercise of Rights, the holding thereof in trust for the Persons entitled
thereto (but reserving to the Fiduciary or to the Fiduciary and the Corporation, as the Corporation may determine, absolute discretion
with respect thereto) and the sale thereof and remittance of the proceeds of such sale, if any, to the Persons entitled thereto.
In no event shall the Corporation or the Rights Agent be required to issue or deliver Rights or securities issuable on exercise
of Rights to Persons who are citizens, residents or nationals of any jurisdiction other than Canada and any province or territory
thereof and the United States of America and any state thereof in which such issue or delivery would be unlawful without registration
of the relevant Persons or securities for such purposes.

| | 5.20 | Regulatory Approvals
| | ---- | --------------------



Any obligation of the Corporation or action or event contemplated
by this Agreement, or any amendment or supplement to this Agreement, shall be subject to receipt of any requisite approval or consent
from any governmental or regulatory authority having jurisdiction, including the Toronto Stock Exchange and any other stock exchange
on which the Corporation’s Securities are listed while any securities of the Corporation are listed and posted for trading
thereon and for a period of 6 months thereafter.



| | 5.21 | U.S. Registration
| | ---- | -----------------



(a) Notwithstanding anything to the contrary, no Rights shall
be deemed issued to a U.S. holder until a registration of the Rights under Section 12(b) of the U.S. Securities Exchange Act of
1934, as amended, is effective, but, regardless of when that registration shall become effective, the Rights shall be effective
in accordance with Section 2 in respect of each Common Share outstanding at the Record Time and each Common Share that may
be issued after the Effective Time and prior to the earlier of the Separation Time and the Expiration Time.



(b) The Corporation shall use its best efforts to (i) file,
as soon as practicable following the Separation Time, a registration statement under the 1933 Act, with respect to the securities
purchasable upon exercise of the Rights on an appropriate form, (ii) cause such registration statement to become effective as soon
as practicable after such filing, and (iii) cause such registration statement to remain effective (with a prospectus at all times
meeting the requirements of the 1933 Act) until the earlier of (A) the date as of which the Rights are no longer exercisable for
such securities, and (B) the Expiration Time. The Corporation will also take such action as may be appropriate under, or to ensure
compliance with, the securities or "blue sky" laws of the various states in connection with the exercisability of the
Rights. The Corporation may temporarily suspend, for a period of time not to exceed ninety (90) days after the date set forth in
clause (i) of the first sentence of this Section 5.21(b), the exercisability of the Rights in order to prepare and file such registration
statement and permit it to become effective. Upon any such suspension, the Corporation shall issue a public announcement stating
that the exercisability of the Rights has been temporarily suspended, as well as a public announcement at such time as the suspension
has been rescinded.



| | 5.22 | 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.

| | 5.23 | Time of the Essence

FOREGOING WILL BECOME VOID WITHOUT ANY FURTHER ACTION.



RIGHTS CERTIFICATE



This certifies that ____________________ or registered assigns,
is the registered holder of the number of Rights set forth above, each of which entitles the registered holder thereof, subject
to the terms, provisions and conditions of the Shareholder Rights Plan Agreement made as of April 27, 2012 (as amended, restated,
or revised the “Rights Agreement”) between ATNA RESOURCES LTD., a corporation incorporated under the Business
Corporations Act (British Columbia) (the “Corporation”), and COMPUTERSHARE TRUST COMPANY OF CANADA, a company
incorporated under the laws of Canada, as rights agent (the “Rights Agent”, which term shall include any successor
Rights Agent under the Rights Agreement), to purchase from the Corporation at any time after the Separation Time and prior to the
Expiration Time (as such terms are defined in the Rights Agreement), one fully paid common share in the capital of the Corporation
(a “Common Share”) (subject to adjustment as provided in the Rights Agreement) at the Exercise Price referred
to below, upon presentation and surrender of this Rights Certificate together with a duly completed and executed Election to Exercise
(as such term is defined in the Rights Agreement) at the principal office of the Rights Agent in the City of Vancouver, Canada.
The Exercise Price (as such term is defined in the Rights Agreement) shall initially be $100.00 per Right and shall be subject
to adjustment in certain events as provided in the Rights Agreement.



This Rights Certificate is subject to all of the terms, provisions
and conditions of the Rights Agreement which terms, provisions and conditions are hereby incorporated herein by this reference
and made a part hereof and to which 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 Rights Agreement are on file at the registered office of the Corporation and are available upon written request.



This Rights Certificate, with or without other Rights Certificates,
upon surrender at any office 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 so 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 provision of the Rights Agreement, the Rights
evidenced by this Rights Certificate may, 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, nor will Rights Certificates be issued for less than one whole Right. In lieu thereof,
a cash payment will be made as provided in the Rights Agreement.



No holder of this Rights Certificate, as such, shall be entitled
to vote (except for those matters solely voted on by holders of Rights as provided in the Right Agreement) or receive dividends
or be deemed for any purpose the holder of Common Shares or of any other securities of the Corporation which may at any time be
issuable upon the exercise hereof, nor shall anything contained in the 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 of the Corporation 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 of the Corporation (except as expressly provided
in the Rights Agreement), or to receive dividends, distributions or subscription rights, or otherwise, until the Rights evidenced
by this Rights Certificate shall have been exercised as provided in the Rights Agreement.



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

Corporation and its corporate seal.
