2.  **<u>Expiry Time</u>:** At the Expiry Time, all rights under the Warrants evidenced hereby, in respect
of which the right of subscription and purchase herein provided for shall not theretofore have been exercised, shall expire and be of
no further force and effect.

3.  **<u>Exercise Procedure</u>:** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Holder may exercise the right to subscribe for and purchase the number of Warrant Shares herein provided
for by surrendering to the Corporation prior to the Expiry Time at its principal office (or such other location as the Corporation may
notify the Holder) this Warrant Certificate, with the Subscription Form attached hereto duly completed and executed by the Holder or its
legal representative or attorney, duly appointed by an instrument in writing in form and manner satisfactory to the Corporation, together
with a certified cheque or bank draft payable to or to the order of the Corporation, or such other means of payment acceptable to the
Corporation in an amount equal to the aggregate Exercise Price in respect of the Warrants so exercised. Any Warrant Certificate so surrendered
shall be deemed to be surrendered only upon delivery thereof to the Corporation at its principal office set forth herein (or to such other
address as the Corporation may notify the Holder).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Upon such delivery as aforesaid, the Corporation shall cause to be issued to the Holder the Warrant Shares
subscribed for not exceeding those which such Holder is entitled to purchase pursuant to this Warrant Certificate and the Holder shall
become a shareholder of the Corporation in respect of the Warrant Shares subscribed for with effect from the date of such delivery and
shall be entitled to delivery of certificates evidencing the Warrant Shares and the Corporation shall cause such certificates to be delivered
to the Holder at the address or addresses specified in such Subscription Form as soon as reasonably practicable, and in any event within
five (5) Business Days of such delivery.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Warrants may not be exercised in the United States or by or on behalf of a U.S. Person unless an exemption
is available from the registration requirements of the U.S. Securities Act and applicable state securities laws and the Holder has furnished
an opinion of counsel of recognized standing in form and substance satisfactory to the Corporation to such effect, and if the Warrants
are so exercised, the certificates representing the Warrant Shares shall bear the necessary legends as determined by legal counsel for
the Corporation.

4.  **<u>Exercise Limitations</u>:** The Corporation shall not effect an exercise of a Warrant, and the
Holder shall not have the right to exercise any portion of a Warrant, pursuant to Section 3 or otherwise, to the extent that, after giving
effect to such issuance after exercise as set forth on the Subscription Form attached hereto, the Holder (and any affiliates, persons
or entities acting as a "group" together with the Holder with respect to the Common Shares for purposes of Section 13(d) of
the United States Securities Exchange Act of 1934, as amended and the rules and regulations promulgated thereunder (the "**Exchange Act** "), and any other persons whose beneficial ownership of the Common Shares would be aggregated with such Holder for purposes
of Section 13(d) off the Exchange Act (such persons, "**Attribution Parties** ")), would beneficially own in excess of the
Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of Common Shares beneficially owned
by the Holder and its Attribution Parties shall include the number of Common Shares issuable upon exercise of a Warrant with respect to
which such determination is being made, but shall exclude the number of Common Shares that would be issuable upon (i) exercise of the
remaining, non- exercised portion of a Warrant beneficially owned by the Holder or any of its Attribution Parties, and (ii) exercise or
conversion of the unexercised or unconverted portion of any other securities of the Corporation (including, without limitation, any other
securities), subject to a limitation on conversion or exercise analogous to the limitation contained herein, beneficially owned by the
Holder or any of its Attribution Parties. Except as set forth in the preceding sentence, for purposes of this Section 4, beneficial ownership
shall be calculated in accordance with Section 13(d) of the Exchange Act, it being acknowledged by the Holder that the Corporation is
not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder further acknowledges
that it is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained
in this Section 4 applies, the determination of whether a Warrant is exercisable (in relation to other securities owned by the Holder
together with any Attribution Parties) and of which portion of a Warrant is exercisable shall be in the sole discretion and at the sole
responsibility of the Holder , and the submission of a Subscription Form shall be deemed to be the Holder's determination of whether
a Warrant is exercisable (in relation to other securities owned by the Holder together with any Attribution Parties) and of which portion
of a Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Corporation shall not have any obligation
to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall
be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes
of this Section 4 in determining the number of outstanding Common Shares, a Holder may rely on the number of outstanding Common Shares
as reflected in (A) the Corporation's most recent periodic or annual report filed with the SEC or on SEDAR+, as the case may be,
(B) a more recent public announcement by the Corporation, or (C) a more recent written notice by the Corporation or the Corporation's
transfer agent setting forth the number of Common Shares outstanding. Upon the written or oral request of a Holder, the Corporation shall,
within two trading days, confirm orally and in writing to the Holder the number of Common Shares then outstanding. In any case, the number
of outstanding Common Shares shall be determined after giving effect to the conversion or exercise of securities of the Corporation, including
the Warrant being exercised, by the Holder or its Attribution Parties since the date as of which such number of outstanding Common Shares
was reported. The "Beneficial Ownership Limitation" shall be 9.90% of the number of Common Shares outstanding immediately
after giving effect to the issuance of Warrant Shares issuable upon exercise of the Warrant in question. The provisions of this paragraph
shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 4 to correct this paragraph
(or any portion hereof) that may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to
make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this Section
4 shall apply to a successor holder of a Warrant.

5.  **<u>Partial Exercise</u>:** The Holder may subscribe for and purchase a number of Warrant Shares less
than the maximum number the Holder is entitled to purchase pursuant to the full exercise of this Warrant Certificate. In the event of
any such subscription prior to the Expiry Time, the Holder shall in addition be entitled to receive, without charge, a new Warrant Certificate
in respect of the balance of the Warrant Shares which the Holder was entitled to subscribe for and purchase pursuant to this Warrant Certificate
and which were then not subscribed for and purchased.

6.  **<u>No Fractional Warrant Shares</u>:** Notwithstanding any adjustments provided for in Section 12
hereof or otherwise, the Corporation shall not be required upon the exercise of any Warrants to issue fractional Warrant Shares in satisfaction
of its obligations hereunder and, in any such case, the number of Warrant Shares issuable upon the exercise of any Warrants shall be rounded
down to the nearest whole number, without payment or compensation in lieu thereof.

7.  **<u>Exchange of Warrant Certificates</u>:** This Warrant Certificate may be exchanged for Warrant
Certificates representing in the aggregate the same number of Warrants and entitling the Holder thereof to subscribe for and purchase
an equal aggregate number of Warrant Shares at the same Exercise Price and on the same terms as this Warrant Certificate.

8.  **<u>Transfer of Warrants</u>:** Subject to applicable securities legislation and the rules, policies,
notices and orders issued by applicable securities regulatory authorities, including the TSXV and Nasdaq (or any other stock exchange
on which the Common Shares are listed), the Holder may transfer this Warrant Certificate by duly completing and executing the Transfer
Form attached hereto. No transfer of this Warrant Certificate shall be made if in the opinion of counsel to the Corporation such transfer
would result in the violation of any applicable securities laws. Subject to the foregoing, the Corporation shall issue and deliver as
soon as practicable, and in any event within five (5) Business Days of receipt of this Warrant Certificate, together with a duly completed
and executed Transfer Form attached hereto, a new Warrant Certificate registered in the name of the permitted transferee or as the permitted
transferee may direct on its behalf and shall take all other necessary actions to effect the transfer as directed.

9.  **<u>Not a Shareholder</u>:** Nothing in this Warrant Certificate or in the holding of a Warrant evidenced
hereby shall be construed as conferring upon the Holder any right or interest whatsoever as a shareholder of the Corporation or as a Warrantholder
of the Corporation.

10.  **<u>No Obligation to Purchase</u>:** Nothing herein contained or done pursuant hereto shall obligate
the Holder to subscribe for or the Corporation to issue any shares or warrants except those Warrant Shares in respect of which the Holder
shall have exercised its right to purchase hereunder in the manner provided herein.

11.  **<u>Covenants</u>:** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Corporation covenants and agrees that so long as any Warrants evidenced hereby remain outstanding,
it shall allot and reserve and there shall remain unissued out of its authorized capital a sufficient number of Warrant Shares to satisfy
the right of purchase provided for herein and upon due exercise of the Warrants in accordance with the terms of the Warrant Certificate
and the Corporation will cause the Warrant Shares subscribed for and purchased in the manner herein provided to be issued and delivered
as directed and such Warrant Shares shall be issued as fully paid and non-assessable Common Shares and free from all taxes, liens and
charges with respect to the issue thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Corporation will do, execute, acknowledge and deliver or cause to be done, executed, acknowledged
and delivered, all other acts, documents, instruments, deeds and assurances in law as the Holder shall reasonably require for the better
accomplishing and effecting of the intentions and provisions of this Warrant Certificate.

12.  **<u>Adjustments</u>:** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) <u>Adjustment</u>: The rights of the Holder, including the number of Warrant Shares issuable upon the
exercise of the Warrants, will be adjusted from time to time in the events and in the manner provided in, and in accordance with the provisions
of, this Section. The purpose and intent of the adjustments provided for in this Section is to ensure that the rights and obligations
of the Holder are neither diminished nor enhanced as a result of any of the events set forth in paragraphs (b), (c) or (d) of this Section.
Accordingly, the provisions of this Section shall be interpreted and applied in accordance with such purpose and intent.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Exercise Price in effect at any date will be subject to adjustment from time to time as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) <u>Share Reorganization</u>: If and whenever at any time during the Adjustment Period, the Corporation
shall (A) subdivide, redivide or change the outstanding Common Shares into a greater number of Common Shares, (B) consolidate, combine
or reduce the outstanding Common Shares into a lesser number of Common Shares, or (C) fix a record date for the issue of, or issue, Common
Shares or securities convertible into or exchangeable for Common Shares to all or substantially all of the holders of Common Shares by
way of a stock dividend or other distribution other than a Dividend Paid in the Ordinary Course, then, in each such event, the Exercise
Price shall, on the record date for such event or, if no record date is fixed, the effective date of such event, be adjusted so that it
will equal the rate determined by multiplying the Exercise Price in effect immediately prior to such date by a fraction, of which the
numerator shall be the total number of Common Shares outstanding on such date before giving effect to such event, and of which the denominator
shall be the total number of Common Shares outstanding on such date after giving effect to such event. Such adjustment shall be made successively
whenever any such event shall occur.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) <u>Rights Offering</u>: If and whenever at any time during the Adjustment Period, the Corporation shall
fix a record date for the issue of rights, options or warrants to all or substantially all of the holders of Common Shares entitling the
holders thereof, within a period expiring not more than 45 days after the record date for such issue, to subscribe for or purchase Common
Shares (or securities convertible into or exchangeable for Common Shares) at a price per share (or having a conversion or exchange price
per share) less than 95% of the Current Market Price on such record date, then the Exercise Price shall be adjusted immediately after
such record date so that it will equal the rate determined by multiplying the Exercise Price in effect on such record date by a fraction,
of which the numerator shall be the total number of Common Shares outstanding on such record date plus the number of Common Shares equal
to the number arrived at by dividing the aggregate price of the total number of additional Common Shares so offered for subscription or
purchase (and the aggregate conversion or exchange price of the convertible or exchangeable securities so offered) by such Current Market
Price, and of which the denominator shall be the total number of Common Shares outstanding on such record date plus
the total number of additional Common Shares so offered for subscription or purchase (or into or for which the convertible or exchangeable
securities so offered are convertible or exchangeable). Any Common Shares owned by or held
for the account of the Corporation or any subsidiary of the Corporation shall be deemed not to be outstanding for the purpose of any such
computation. To the extent that any such rights, options or warrants are not exercised prior to the expiration thereof, the Exercise Price
shall then 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, options or warrants, as the case may be.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) <u>Distribution</u>: If and whenever at any time during the Adjustment Period, the Corporation shall fix
a record date for the making of a distribution to all or substantially all of the holders of Common Shares of (A) shares of any class
other than Common Shares whether of the Corporation or any other corporation, (B) rights, options or warrants to acquire Common Shares
or securities exchangeable for or convertible into Common Shares or property or other assets of the Corporation (other than a rights offering
as described in Section 12(b)(ii) hereof), (C) evidences of indebtedness, or (D) cash, securities or other property or assets then, in
each such case and if such distribution does not constitute a Dividend Paid in the Ordinary Course, or fall under clauses (i) or (ii)
above, the Exercise Price will be adjusted immediately after such record date so that it will equal the rate determined by multiplying
the Exercise Price in effect on such record date by a fraction, of which the numerator shall be the total number of Common Shares outstanding
on such record date multiplied by the Current Market Price on the earlier of such record date and the date on which the Corporation announces
its intention to make such distribution, less the aggregate fair market value (as determined by the directors, acting reasonably, at the
time such distribution is authorized) of such shares or rights, options or warrants or evidences of indebtedness or cash, securities or
other property or assets so distributed, and of which the denominator shall be the total number of Common Shares outstanding on such record
date multiplied by such Current Market Price. Any Common Shares owned by or held for the account of the Corporation, or any subsidiary
of the Corporation, shall be deemed not to be outstanding for the purpose of any such computation. To the extent that any such rights,
options or warrants so distributed are not exercised prior to the expiration thereof or any such shares, evidences of indebtedness or
cash, securities or other property or assets are not so distributed, the Exercise Price shall then be readjusted to the Exercise Price
which would then be in effect based upon such rights, options or warrants or shares, evidences of indebtedness or cash, securities or
other property or assets actually distributed or based upon the number or amount of securities or the property or assets actually issued
or distributed upon the exercise of such rights, options or warrants, as the case may be.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) <u>Reclassifications</u>: If and whenever at any time during the Adjustment Period, there is (A) any reclassification of, or redesignation of or amendment to the outstanding Common Shares, any change or exchange of the Common
Shares into other shares or securities or property or any other reorganization of the Corporation (other than as described in Section
12(b) hereof), (B) any consolidation, amalgamation, arrangement, merger or other form of business combination of the Corporation with
or into any other corporation or entity resulting in any reclassification of, or redesignation of or amendment to the outstanding Common
Shares, any change or exchange of the Common Shares into other shares or securities or property or any other reorganization of the Corporation, or (C) any sale, lease, exchange or transfer of the undertaking or assets of the Corporation as an entirety
or substantially as an entirety to another corporation or entity, then, in each such event, the Holder of this Warrant Certificate which
is thereafter exercised shall be entitled to receive, and shall accept, in lieu of the number of Warrant Shares to which such Holder was
theretofore entitled upon such exercise, the kind and number or amount of shares or other securities or property which such Holder would
have been entitled to receive as a result of such event as if, on the effective date or record date thereof, such Holder had been the
registered holder of the number of Warrant Shares to which such Holder was theretofore entitled upon such exercise. If necessary as a
result of any such event, appropriate adjustments will be made in the application of the provisions set forth in this subsection with
respect to the rights and interests thereafter of the Holder of this Warrant Certificate to the end that the provisions set forth in this
subsection will thereafter correspondingly be made applicable, as nearly as may reasonably be, in relation to any shares or other securities
or property thereafter deliverable upon the exercise of this Warrant Certificate. Any such adjustments in the application of the provisions
set forth in this subsection will be made by and set forth in an instrument supplemental hereto approved by the directors, acting reasonably,
and shall for all purposes be conclusively deemed to be an appropriate adjustment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) <u>Issuable Warrant Shares Adjustment</u>: If at any time during the Adjustment Period any adjustment
or readjustment in the Exercise Price shall occur pursuant to the provisions of Section 12(b) hereof, then the number of Warrant Shares
purchasable upon the subsequent exercise of the Warrants shall be simultaneously adjusted or readjusted, as the case may be, by multiplying
the number of Warrant Shares purchasable upon the exercise of the Warrants immediately prior to such adjustment or readjustment by a fraction
which shall be the reciprocal of the fraction used in the adjustment or readjustment of the Exercise Price.

13.  **<u>Rules Regarding Calculation of Adjustment of Exercise Price</u>:** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The adjustments provided for in Section 12 hereof are cumulative and will, in the case of adjustments
to the Exercise Price, be computed to the nearest whole Warrant Share and will be made successively whenever an event referred to therein
occurs, subject to the following subsections of this Section 13.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) No adjustment in the Exercise Price is required to be made unless such adjustment would result in a change
of at least 1% in the prevailing Exercise Price and no adjustment in the Exercise Price is required unless such adjustment would result
in a change of at least one one-hundredth of a Warrant Share; provided, however, that any adjustments which, except for the provisions
of this subsection, would otherwise have been required to be made, will be carried forward and taken into account in any subsequent adjustments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) No adjustment in the Exercise Price will be made in respect of any event described in Section 12 hereof,
other than the events referred to in Section 12(c) hereof, if the Holder is entitled to participate in such event on the same terms, *mutatis mutandis*, as if the Holder had exercised this Warrant prior to or on the effective date or record date of such event.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) No adjustment in the Exercise Price will be made under Section 12 hereof in respect of the issue from
time to time of Common Shares issuable from time to time as Dividends Paid in the Ordinary Course to holders of Common Shares who exercise
an option or elect to receive substantially equivalent dividends in Common Shares in lieu of receiving a cash dividend or in respect of
a distribution of Common Shares as compensation securities or pursuant to the exercise or vesting of stock options or other compensation
securities granted under incentive plans of the Corporation or pursuant to the conversion, exchange, redemption or exercise of any convertible,
exchangeable, redeemable or exercisable securities outstanding as of the date hereof (or pursuant to the conversion, exchange, redemption
or exercise of any securities issued upon any such conversion, exchange, redemption or exercise).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) If at any time a question or dispute arises with respect to adjustments provided for in Section 12 hereof,
such question or dispute will be conclusively determined by the auditor of the Corporation or, if they are unable or unwilling to act,
by such other firm of independent chartered accountants as may be selected by action of the directors of the Corporation and any such
determination, subject to regulatory approval and absent manifest error, will be binding upon the Corporation and the Holder. The Corporation
will provide such auditor or chartered accountant with access to all necessary records of the Corporation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) In case the Corporation after the date of issuance of this Warrant Certificate takes any action affecting
the Common Shares, other than an action described in Section 12 hereof, which in the opinion of the board of directors of the Corporation
would materially affect the rights of the Holder, the Exercise Price will be adjusted in such manner, if any, and at such time, by action
of the directors of the Corporation in their sole discretion, acting reasonably and in good faith, but subject in all cases to any necessary
regulatory approval including approval of the TSXV, Nasdaq or such other stock exchange or market place on which the Common Shares are
then listed or quoted for trading, if such approval is required. Failure of the taking of action by the directors of the Corporation so
as to provide for an adjustment on or prior to the effective date of any action by the Corporation affecting the Common Shares will be
conclusive evidence that the board of directors of the Corporation has determined that it is equitable to make no adjustment in the circumstances.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) If the Corporation sets a record date to determine the holders of the Common Shares for the purpose of
entitling them to receive any dividend or distribution or sets a record date to take any other action and, thereafter and before the distribution
to such shareholders of any such dividend or distribution or the taking of any other action, decides not to implement its plan to pay
or deliver such dividend or distribution or take such other action, then no adjustment in the Exercise Price will be required by reason
of the setting of such record date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) In the absence of a resolution of the directors of the Corporation fixing a record date for any event
which would require any adjustment to this Warrant, the Corporation will be deemed to have fixed as the record date therefor the date
on which the event is effected.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) As a condition precedent to the taking of any action which would require any adjustment to this Warrant,
including the Exercise Price, the Corporation shall take any corporate action which may be necessary in order that the Corporation or
any successor to the Corporation or successor to the undertaking or assets of the Corporation have unissued and reserved in its authorized
capital and may validly and legally issue as fully paid and non-assessable all the shares or other securities which the Holder is entitled
to receive on the full exercise thereof in accordance with the provisions hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) The Corporation covenants to and in favour of the Holder that so long as this Warrant Certificate remains
outstanding, it will give notice to the Holder of the effective date or of the record date for any event referred to in Section 11 hereof,
and, in each case, such notice shall specify the particulars of such event and the record date and the effective date for such event and,
if determinable, the required adjustment and the calculation of such adjustment; provided that the Corporation shall only be required
to specify in such notice such particulars of such event as have been fixed and determined on the date on which such notice is given.
Such notice shall be given not less than 21 days in each case prior to such applicable record date or effective date. In case any adjustment
for which a notice in Section 12 has been given is not then determinable, the Corporation shall promptly after such adjustment is determinable
deliver to the Holder a certificate providing the calculation of such adjustment. Subject to Section 16, the Corporation hereby covenants
and agrees that the register of transfers and transfer books for the Common Shares and warrants will be open, and that the Corporation
will not take any action which might deprive the Holder of the opportunity of exercising the rights of subscription contained in this
Warrant Certificate, during such 21 day period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) In any case that an adjustment pursuant to Section 12 hereof shall become effective immediately after
a record date for or an effective date of an event referred to herein, the Corporation may defer, until the occurrence and consummation
of such event, issuing to the Holder of this Warrant Certificate, if exercised after such record date or effective date and before the
occurrence and consummation of such event, the additional Warrant Shares or other securities or property issuable upon such exercise by
reason of the adjustment required by such event, provided, however, that the Corporation will deliver to the Holder an appropriate instrument
evidencing the Holder's right to receive such additional Warrant Shares or other securities or property upon the occurrence and
consummation of such event and the right to receive any dividend or other distribution in respect of such additional Warrant Shares or
other securities or property declared in favour of the holders of record of Common Shares or of such other securities or property on or
after the date of exercise of the Warrant Shares or such later date as the Holder would, but for the provisions of this subsection, have
become the holder of record of such additional Warrant Shares or of such other securities or property.

14.  **<u>Consolidation and Amalgamation</u>:** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Corporation shall not enter into any transaction whereby all or substantially all of its undertaking,
property and assets would become the property of any other corporation (herein called a "**successor corporation**") whether
by way of reorganization, reconstruction, consolidation, arrangement, amalgamation, merger, transfer, sale, disposition or otherwise,
unless prior to or contemporaneously with the consummation of such transaction the Corporation and the successor corporation shall have
executed such instruments and done such things as the Corporation, acting reasonably, considers necessary or advisable to establish that
upon the consummation of such transaction:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the successor corporation will have assumed all the covenants and obligations of the Corporation under
this Warrant Certificate, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the Warrants and the terms set forth in this Warrant Certificate will be valid, legal and binding obligations
of the successor corporation entitling the Holder, as against the successor corporation, to all the rights and benefits of the Holder
under this Warrant Certificate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Whenever the conditions of Section 14(a) hereof shall have been duly observed and performed the successor
corporation shall possess, and from time to time may exercise, each and every right and power of the Corporation under this Warrant Certificate
in the name of the Corporation or otherwise and any act or proceeding by any provision hereof required to be done or performed by any
director or officer of the Corporation may be done and performed with like force and effect by the like directors or officers of the successor
corporation.

15.  **<u>Representation and Warranty</u>:** The Corporation hereby represents and warrants to the Holder
that the Corporation is duly authorized and has all corporate power and capacity to create and issue the Warrants evidenced hereby and
the Warrant Shares issuable upon the exercise hereof and perform its obligations hereunder and that this Warrant Certificate represents
a valid, legal and binding obligation of the Corporation enforceable against the Corporation in accordance with its terms, subject to
customary exceptions.

16.  **<u>If Share Transfer Books Closed</u>:** The Corporation shall not be required to deliver certificates
for Warrant Shares while the securities transfer books of the Corporation are properly closed, prior to any meeting of shareholders or
for the payment of dividends or for any other purpose, and in the event of the surrender of any Warrant in accordance with the provisions
hereof and the making of any subscription and payment for the Warrant Shares called for thereby during any such period, delivery of certificates
for Warrant Shares may be postponed for a period not exceeding three Business Days after the date of the re-opening of said securities
transfer books provided that any such postponement of delivery of certificates shall be without prejudice to the right of the Holder,
if the Holder has surrendered the same and made subscription and payment during such period, to receive such certificates for the Warrant
Shares called for after the securities transfer books shall have been re-opened and shall be without prejudice to the rights of the Holder
pursuant to this Warrant Certificate and the Warrant Shares that would have otherwise been issued had it not been for such postponement.

17.  **<u>Lost Certificate</u>:** If the Warrant Certificate evidencing the Warrants issued hereby becomes
stolen, lost, mutilated or destroyed the Corporation may, on such terms as it may in its discretion, acting reasonably, impose, issue
and countersign a new Warrant Certificate of like denomination, tenor and date as the Warrant Certificate so stolen, lost, mutilated or
destroyed.

18.  **<u>Governing Law</u>:** This Warrant Certificate shall be governed by, and construed in accordance
with, the laws of the Province of Ontario and the federal laws of Canada applicable therein.

Certificate should be or become invalid, illegal or unenforceable in any respect in any jurisdiction, the remaining provisions or parts

**Comment for Reporting Person:** Includes 1,401,919 Common Shares (as defined in Item 2(a)) issuable upon exercise of warrants and 2,184,440 Common Shares issuable upon conversion of convertible notes. As more fully described in Item 5, the reported warrants and convertible notes are subject to 9.9% beneficial ownership blockers and the percentage set forth in row (13) gives effect to such blockers.  However, rows (7), (9) and (11) show the number of Common Shares that would be issuable upon the full exercise of the reported warrants and  the full conversion of the reported convertible notes.  Therefore, the actual number of Common Shares beneficially owned by such Reporting Person, after giving effect to such blockers, is less than the number of securities reported in rows (7), (9) and (11).

**Item 1. Security and Issuer**

**(a) Title of Class of Securities:**
Common Shares, no par value

**(b) Name of Issuer:**
Electra Battery Materials Corp

**(c) Address of Issuer's Principal Executive Offices:**
SUITE 3200, BAY ADELAIDE CENTRE, 40 TEMPERANCE ST., TORONTO, A6, M5H 0B4

**Item 4. Purpose of Transaction**

The Reporting Person originally acquired the securities reported herein for investment purposes in the ordinary course of business and not with the purpose, nor with the effect, of changing or influencing the control or management of the Issuer.

The Reporting Person has engaged in, and intends to continue to engage in, communications with the Issuer's management and board of directors, other current and prospective holders of the Issuer's equity and debt securities, and other third parties about, and intends to negotiate agreements with the Issuer regarding, a broad range of consensual transactions intended to deleverage and recapitalize the Issuer to support the Issuer's continued operations and development of its cobalt sulfate refinery. Any such transactions may involve, among other things, changes in the Issuer's capital structure, corporate governance, constituent documents and board composition, the exchange of some or all of the securities and royalty rights reported herein for newly issued equity or debt securities of the Issuer and its subsidiaries, and the acquisition of newly issued equity or debt securities of the Issuer and its subsidiaries for cash. Any such transactions may result in the Reporting Person and the Named Holders (as defined below) requesting or obtaining representation on the Issuer's board of directors, acquiring control of a majority of the Issuer's outstanding equity securities, or any of the matters set forth in clauses (a)-(j) of Item 4 of Schedule 13D.

With respect to the foregoing, the Reporting Person has initiated discussion with the holders of the Issuer's debt securities named in Item 5 hereto (the "Named Holders"). The Reporting Person, together with the Named Holders, may engage with the Issuer on the matters set forth in the preceding paragraph, and may in the future take actions concerning its respective investments in the Issuer with respect thereto.  There can be no guarantee that the Reporting Person will make any proposal regarding any of the matters set forth in the preceding paragraph, either on its own or in conjunction with some or all of the Named Holders, and if any such proposal is made, the Reporting Person can provide no assurances such proposal will be accepted or that it will successfully consummate any proposed transaction. To facilitate its consideration of such matters, the Reporting Person, together with the Named Holders, have retained, or intend to retain, consultants, legal counsel and advisors.

The Reporting Person may also, from time to time, engage in discussions with members of the Issuer's management and board of directors, other current and prospective holders of the Issuers' equity and debt securities, industry analysts, existing or potential strategic partners or competitors, investment and financing professionals, equity and debt financing sources and other third parties regarding a variety of matters relating to the Issuer, which (in addition to the matters discussed above) may include, among other things, the Issuer's business, management, capital structure, capital allocation, corporate governance, board composition and strategic alternatives and direction, and may take other steps seeking to bring about changes to increase shareholder value as well as pursue other plans or proposals that relate to or could result in any of the matters set forth in clauses (a)-(j) of Item 4 of Schedule 13D.

The Reporting Person intends to review its investment in the Issuer on a continuing basis. Depending on various factors, including, without limitation, the outcome of any discussions and negotiations referenced above, the Issuer's financial position and investment strategy, results and strategic direction, actions taken by the Issuer's management and board of directors, price levels of the Issuer's securities, other investment opportunities available to the Reporting Person, conditions in the securities market, and general economic and industry conditions, the Reporting Person intends to consider, explore, and develop plans and may in the future take such actions with respect to its investment in the Issuer as they deem appropriate, including, without limitation, engaging in communications with the Issuer's management and board of directors, engaging in discussions with holders of the Issuer's equity and debt securities and others about the Issuer and the Reporting Person's investment, making proposals to the Issuer concerning changes to the capital allocation strategy, capitalization, ownership structure, strategic transactions, including business combinations, a sale of the Issuer as a whole or in parts or acquisitions or investments by the Issuer, board composition and structure, operations of the Issuer, purchasing additional securities of the Issuer, selling some or all of its securities of the Issuer, engaging in short selling of or any hedging or similar transaction with respect to the securities of the Issuer, or take any other actions with respect to its investment in the Issuer permitted by law, including any or all of the actions set forth in paragraphs (a)-(j) of Item 4 of Schedule 13D. The Reporting Person may at any time reconsider and change its plans or proposals relating to the foregoing.

**Item 5. Interest in Securities of the Issuer**

**(a)**
See rows (11) and (13) of the cover page to this Schedule 13D for the aggregate number of  Common Shares and percentages of the Common Shares beneficially owned by the Reporting Person. The aggregate percentage of Common Shares reported to be beneficially owned by the Reporting Person is based upon 17,962,173 Common Shares outstanding as of June 25, 2025, as reported in the  Registration Statement on Form F-3 filed with the Securities and Exchange Commission (the "SEC") on June 27, 2025, and assumes exercise of  warrants and conversion of convertible notes, subject to the 9.9% Blockers (as defined below).

It has come to the attention of the Reporting Person that as of December 31, 2022, the Reporting Person triggered a Schedule 13G reporting obligation as a result of the Common Shares becoming registered under Section 12 of the Exchange Act during 2022. As of December 31, 2022, the Reporting Person may have been deemed to beneficially own 2,254,588 Common Shares issuable upon conversion of convertible notes, which represented 6.0% of the outstanding Common Shares which is based upon 35,185,977 Common Shares outstanding as of December 31, 2022, as reported in the Issuer's Annual Report on Form 40-F for the fiscal year ended December 31, 2022 filed with the SEC on April 5, 2023, and assumes conversion of the convertible notes held at such time.  As of December 31, 2023, the Reporting Person held warrants exercisable and convertible notes convertible into an aggregate of 10,557,466 Common Shares, which, due to the 9.9% Blockers, represented beneficial ownership of 9.9% of the outstanding Common Shares which is based upon 55,851,327 Common Shares outstanding as of December 31, 2023, as reported in the Issuer's Annual Report on Form 20-F for the fiscal year ended December 31, 2023 filed with the SEC on May 16, 2024. The positions reported as of December 31, 2022 and as of December 31, 2023 have not been adjusted to reflect the 1-for-4 reverse stock split effected by the Issuer on January 2, 2025. The Reporting Person's beneficial ownership percentage has remained at 9.9% of the outstanding Common Shares from December 31, 2023 through the date of the filing of this statement.

Pursuant to the terms of the warrants and convertible notes beneficially owned by the Reporting Person referred to in this filing, the Reporting Person cannot (and could not) exercise or convert any of the warrants and/or convertible notes if the Reporting Person (or any "group" of which the Reporting Person is a member) would beneficially own, after any such exercise or conversion, as applicable, more than 9.9% of the outstanding Common Shares (the "9.9% Blockers"). Consequently, at this time, the Reporting Person is not able, and as of December 31, 2023, the Reporting Person was not able, to exercise or convert all of such warrants and convertible notes due to the 9.9% Blockers. The percentage set forth in Row (13) of the cover page and in the footnote set forth on the cover page for the Reporting Person give effect to the 9.9% Blockers.

As a result of the Reporting Person's involvement in the discussions and potential actions described in Item 4 of this Schedule 13D, the Reporting Person and the Named Holders may be deemed to be member of a "group" for the purposes of Section 13(d)(3) of the Exchange Act, which may consist of the Reporting Person, Whitebox Advisors LLC, Whitebox General Partner LLC and O'Connor, a distinct business unit of UBS Asset Management (Americas) LLC.  The "group" may be deemed to have acquired beneficial ownership of all the shares beneficially owned by each member of the "group," subject to the 9.9% Blockers. As such, the "group" may be deemed to beneficially own in the aggregate 1,925,360 Common Shares, or 9.9% of the outstanding Common Shares, as calculated pursuant to Rule 13d-3(d)(1)(i) under the Exchange Act. On information and belief, the Reporting Person understands that the Named Holders are filing Schedule 13D separately from the Reporting Person.  Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission by the Reporting Person that it is a group with the Named Holders or the beneficial owner of any of the Common Shares beneficially owned by any Named Holder for purposes of Section 13(d) of the Act or for any other purpose, and such beneficial ownership is expressly disclaimed.

**(b)**
See rows (7) through (10) of the cover page to this Schedule 13D for the number of Common Shares as to which the Reporting Person has the sole or shared power to vote or direct the vote and sole or shared power to dispose or to direct the disposition.

**(c)**
All transactions in the Common Shares effected by the Reporting Person during the past sixty (60) days, which were all in the open market, are set forth in Schedule B, and are incorporated herein by reference. In addition, on June 10, 2025, the Highbridge Funds exercised warrants to purchase an aggregate of 1,000 Common Shares at a price of $1.40 per share.
