**Electra Battery Materials Corporation**

**FORM 51-102F3<br> MATERIAL CHANGE REPORT**

|:---|:---|
| &nbsp;&nbsp;**ITEM 1** | &nbsp;&nbsp;**NAME AND ADDRESS**<br>Electra Battery Materials Corporation. (the "**Company**")<br> 133 Richmond Street W, Suite 602<br> Toronto, Ontario<br> M5H 2L3 |
| &nbsp;&nbsp;**ITEM 2** | &nbsp;&nbsp;**DATE OF MATERIAL CHANGE**<br>February 8, 2023 |
| &nbsp;&nbsp;**ITEM 3** | &nbsp;&nbsp;**NEWS RELEASE**<br>The Company issued a news release on February 8, 2023 announcing the material change, which was disseminated through Business Wire and subsequently filed on SEDAR. |
| &nbsp;&nbsp;**ITEM 4** | &nbsp;&nbsp;**SUMMARY OF MATERIAL CHANGE**<br>On February 8, 2023, the Company entered into subscription agreements with certain institutional investors in the United States with respect to US$51 million principal amount of 8.99% senior secured convertible notes (the "**Notes**"). The investors in the offering (the "**Note Offering**") also received an aggregate of 10,796,054 warrants (each a "**Warrant**") to purchase common shares in the capital of the Corporation (each a "**Common Share**"). The Note Offering was completed on February 13, 2023.<br>The Company used a portion of the proceeds of the Note Offering to purchase all of the outstanding approximately US$36 million of existing 6.95% senior secured notes due December 2026 (the "**2026 Notes**") for cancellation at par, as well as to pay accrued and unpaid interest on the 2026 Notes through the closing date of the Note Offering.<br>The net proceeds of the Note Offering to the Company, after the purchase and cancellation of the 2026 Notes and payment of accrued and unpaid interest thereon, is approximately US$14 million. |

|:---|:---|
| &nbsp;&nbsp;**ITEM 5** | &nbsp;&nbsp;**FULL DESCRIPTION OF MATERIAL CHANGE**<br>On February 8, 2023, the Company announced the Note Offering and the issuance of the Warrants, with a portion of the Note Offering being used to purchase all of the outstanding approximately US$36 million principal amount of 2026 Notes for cancellation at par, plus accrued and unpaid interest through the Closing Date of the Note Offering for net proceeds to the Company of approximately US$14 million after the purchase and cancellation of the 2026 Notes and payment of accrued and unpaid interest to February 13, 2023. The net proceeds of the Note Offering will be used to finance capital expenditures associated with the expansion and recommissioning of the Company's wholly-owned hydrometallurgical cobalt refinery (the "**Refinery**") located in Ontario, Canada, including buildings, equipment, infrastructure, and other direct costs, as well as engineering and project management costs, and transaction costs associated with the Note Offering and repurchase of the 2026 Notes.<br>Upon completion of the Note Offering and purchase and cancellation of the 2026 Notes, the Company has US$51 million principal amount of Notes outstanding and no 2026 Notes outstanding.<br>Upon closing of the Note Offering, the Company entered into a note indenture (the "**Note Indenture**") with the trustee for the Notes (the "**Trustee**"), as well as other customary associated security documentation, and a warrant indenture with respect to the Warrants (the "**Warrant Indenture**").<br>The initial conversion rate of the Notes is 403.2140 Common Shares per US$1,000 principal amount of Notes (equivalent to an initial conversion price of approximately US$2.48 per Common Share) subject to certain adjustments set forth in the Note Indenture (the "**Conversion Price**").<br>The Notes bear interest at 8.99% per annum, payable in cash semi-annually in arrears in February and August of each year, and mature in February 2028. During the first 12 months of the term of the Notes, the Company may pay interest through the issuance of Common Shares at an increased annual interest rate of 11.125%. In the event the Company achieves a third-party green bond designation during the term of the Note Indenture, the interest rate on future cash interest payments shall be reduced to 8.75% per year and the interest rate of future interest paid through the issuance of Common Shares shall be reduced to 10.75% per year.<br>The Company is the borrower under the Notes, and the obligations are guaranteed by the Company's Canadian, United States, and Australian subsidiaries, as well as any other subsidiary that guarantees the Company's obligations from time to time, subject to certain customary exclusions. The Notes are secured by a first priority security interest (subject to customary permitted liens) in substantially all of the Company's assets, and the assets and/or equity of the secured guarantors.<br>The initial noteholders also received a royalty of (i) 0.6% on "Operating Revenue" from the sale of all cobalt produced from the Refinery payable in the first twelve months following a defined threshold of commercial production, where "Operating Revenue" consists of revenue from the Refinery less certain permitted deductions; and (ii) 0.6% on all revenue from sales of cobalt generated from the Refinery in the second to fifth years following the commencement of commercial production. Royalty payments under the royalty agreements are subject to a cumulative cap of US$6.0 million. Payment of the royalty is secured by a first priority security interest (subject to customary permitted liens) in substantially all of the Company's assets, and the assets and/or equity of the secured guarantors.<br>|

---

&nbsp;&nbsp;The Indenture contains certain positive and negative covenants in favour of the Trustee for the benefit of the Noteholders. The Company will be obligated to make an offer to repurchase a portion of the Notes at par, or in their entirety at a premium of 105% to par, in certain circumstances. After the second anniversary of the issue date of the Notes, the Company may mandate the conversion of the Notes at its option in the event the trading price of the Common Shares exceeds 150% of the conversion price of the Notes at such time for at least 20 trading days, whether consecutive or not, during any consecutive 30 trading day period.<br>The Notes will also be subject to customary events of default, dilution protection and limitations on beneficial ownership.<br>Upon any early conversion of Notes, the Company will make an interest make-whole payment equal to the lesser of the two years of interest payments or interest payable to maturity, which may be made in cash or Common Shares at the Company's election. The Note Indenture also provides for payments to be made in the event of a fundamental change, such as a change of control. In accordance with the policies of the TSX Venture Exchange ("**TSXV**"), for as long as the Company is listed on the TSXV, aggregate consideration that is deemed "interest" under the Notes which, for clarity, does not include value realized on conversion of Notes or Warrants, but includes royalty payments, is capped at 24% per year absent TSXV approval.<br>The Warrants are exercisable for five years at an exercise price of US$2.48.<br>Certain price-based adjustment mechanisms apply to the Notes and the Warrants, such that, provided the Company is not listed on TSXV at the time, if on the eight month anniversary of the issuance of the Notes, the 20-day volume-weighted average trading price ("**VWAP**") of the Common Shares immediately prior to such date is less than 85% of the reference price used to determine the conversion price of the Notes and the exercise price of the Warrants (the "Reference Price"), the Company will be required to make an offer to the Noteholders and Warrantholders to exchange all the outstanding Notes and Warrants for new securities that are substantially identical to the Notes and Warrants within 35 days of such offer (a "Securities Exchange"), except that (i) the principal amount of exchanged notes shall be increased by any accrued and unpaid interest on the Notes otherwise payable through the exchange date, (ii) the minimum length of the term of the new securities would be five years from the date of issuance of the new securities, and (iii) the conversion rate and the conversion price or exercise price of the new securities would be equal to a 17.5% premium to the VWAP on the date of such exchange, subject to certain applicable minimums.<br>A Securities Exchange cannot occur for as long as the Company is listed on TSXV. The Company has agreed to certain positive covenants with the Trustee and the warrant agent in favour of the Noteholders and Warrantholders in the event the Company is required to pay Noteholders "deemed interest" in excess of 24% under the Notes but is prevented from being paid such entitlement pursuant to TSXV policies, or to effect a Securities Exchange, including, if on the six-month anniversary of the issuance of the Notes, the VWAP is less than 85.0% of the Reference Price, or the Company has not secured additional investment of at least US$10 million through a sale of Common Shares, the Company will take steps to either obtain approval of the TSXV for a Securities Exchange or de-list the Common Shares from TSXV and relist the Common Shares for trading on a Canadian securities exchange other than TSXV, if required.<br>

---

| | |
|:---|:---|
|  | &nbsp;&nbsp;The Common Shares issuable pursuant to the terms of the Notes and/or the Warrants will be subject to customary registration rights.<br>Additional details with respect to the Notes, Warrants and royalty are available in the Company's news releases dated February 8 and February 13, 2023, as well as in the Note Indenture and the Warrant Indenture, each of which will be filed on SEDAR and EDGAR.<br>Cantor Fitzgerald & Co. ("**CF&Co**") acted as sole placement agent for the Note Offering and received a cash fee equal to 4% of the difference between the principal amount of Notes issued and the outstanding principal amount of 2026 Notes, a portion of which cash fee was satisfied by the issuance of 27,500 Common Shares at a price of US$2.18, as well as an additional placement agent fee of 50,000 Common Shares. |

are binding on the Corporation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Except as described above or as may be directed by the Corporation, registration of interests in and transfers
of Warrants shall be made only through the Book-Based System. Other than as may be directed by the Corporation, the Warrants will be evidenced
by a non-certificated inventory ()"**NCI**") deposit though the Book-Based System for an amount representing the aggregate
number of such Warrants outstanding from time to time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Transfers of beneficial ownership in any Warrant represented by an NCI deposit will be effected only (i) with
respect to the interest of a Depository Participant, through records maintained by the Depository or its nominee for such Warrants, and
(ii) with respect to the interest of any person other than a Depository Participant, through records maintained by the Depository
Participants.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) The rights of Beneficial Owners who hold security entitlements in respect of Warrants through the Book-Based
System shall be limited to those established by applicable law and agreements between the Depository and the Depository Participants and
between such Depository Participants and Beneficial Owners who hold security entitlements in respect of Warrants through the Book-Based
System and must be exercised through a Depository Participant in accordance with the rules and procedures of the Depository.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) If any of the following events occurs:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the Depository or the Corporation has notified the Warrant Agent that (A) the Depository is unwilling
or unable to continue as depository or (B) the Depository ceases to be a clearing agency in good standing under applicable laws and,
in either case, the Corporation is unable to locate a qualified successor depository within 90 days of delivery of such notice;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the Corporation has determined, in its sole discretion, to terminate the Book-Based System in respect
of such Uncertificated Warrants and has communicated such determination to the Warrant Agent in writing;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) the Corporation or the Depository is required by applicable law to take the action contemplated in this
subsection; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the Book-Based System administered by the Depository ceases to exist,

then one or more definitive fully registered Warrant Certificates shall be executed by the Corporation and Authenticated and delivered by the Warrant Agent to the Depository in exchange for the Uncertificated Warrants held by the Depository. Fully registered Warrant Certificates issued and exchanged pursuant to this subsection shall be registered in such names and in such denominations as the Depository shall instruct the Warrant Agent, provided that the aggregate number of Warrants represented by such Warrant Certificates shall be equal to the aggregate number of Uncertificated Warrants so exchanged. Upon exchange of Uncertificated Warrants for one or more Warrant Certificates in definitive form, such Uncertificated Warrants shall be cancelled by the Warrant Agent.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) Notwithstanding anything in this Indenture in terms of a NCI deposit, neither the Corporation nor the
Warrant Agent nor any agent thereof shall have any responsibility or liability for:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the records maintained by the Depository relating to any ownership interests or any other interests in
the Warrants or the depository system maintained by the Depository, or payments made on account of any ownership interest or any other
interest of any person in any Warrant represented by any NCI deposit (other than the Depository or its nominee);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) maintaining, supervising or reviewing any records of the Depository or any the Depository Participant
relating to any such interest; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) any advice or representation made or given by the Depository or those contained in this Indenture that
relate to the rules and regulations of the Depository or any action to be taken by the Depository on its own direction or at the
direction of any the Depository Participant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) Notwithstanding any provisions made in this Indenture with respect to expiry dates, payment dates or other
acts that may be required to be done in connection with this Indenture, such provisions, dates and acts may be altered due to the internal
procedures and processes with respect to cut-off times of the Depository. It is understood and agreed to by the parties hereto that the
Warrant Agent shall have no responsibility in connection with any cut-off time imposed by the Depository.

**3.13** **Adjustment of Number of Common Shares and Exercise Price.** 

Subject to Section 3.14, the subscription rights in effect under the Warrants for Common Shares issuable upon the exercise of the Warrants shall be subject to adjustment from time to time as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) If and whenever, at any time after the date hereof and prior to the Time of Expiry, the Corporation shall:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) issue Common Shares or securities exchangeable for or convertible into Common Shares to all or substantially
all the holders of the Common Shares as a stock dividend or other distribution (other than a distribution of Warrant Shares upon exercise
of the Warrants or pursuant to the exercise, conversion or exchange of securities of the Corporation outstanding as of the date hereof),
or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) subdivide, redivide or change its then outstanding Common Shares into a greater number of Common Shares,
or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) reduce, combine or consolidate its then outstanding Common Shares into a lesser number of Common Shares,
(any of such events in these paragraphs (a), (b) or (c) being called a "**Common Share Reorganiz** ation"), then
the Exchange Basis in effect on the effective date of such subdivision, redivision or change, or reduction, combination or consolidation,
or on the record date of such stock dividend or other distribution, as the case may be, shall be adjusted by multiplying the Exchange
Basis in effect immediately prior to such effective date or record date by a fraction:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the numerator of which shall be the total number of Common Shares outstanding on such date immediately
after giving effect to such Common Share Reorganization (including, in the case where securities exercisable, exchangeable for or convertible
into Common Shares are distributed, the number of Common Shares that would have been outstanding had such securities been exercised, or
exchanged for or converted into Common Shares on such record date, assuming in any case where such securities are not then convertible,
exercisable or exchangeable but subsequently become so, that they were convertible, exercisable or exchangeable on the record date on
the basis upon which they first become convertible, exercisable or exchangeable), and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) the denominator of which shall be the total number of Common Shares outstanding on such date before giving
effect to such Common Share Reorganization.

The resulting product, adjusted to the nearest 1/100th, shall thereafter be the Exchange Basis until further adjusted as provided in this Article 3.

Any Common Shares owned by or held for the account of the Corporation or any of its Subsidiaries or a partnership in which the Corporation is directly or indirectly a party to will be deemed not to be outstanding for the purposes of any computation.

To the extent that any adjustment in the Exchange Basis occurs pursuant to this subsection 3.13(1) as a result of the fixing by the Corporation of a record date for the distribution of securities exchangeable or exercisable for or convertible into Common Shares and the Common Share Reorganization does not occur or any conversion, exercise or exchange rights are not fully converted, exercised or exchanged, the Exchange Basis shall be readjusted immediately after the expiry of any relevant exchange or conversion right or the termination of the Common Share Reorganization, as the case may be, to the Exchange Basis that would then be in effect, based upon the number of Common Shares actually issued and remaining issuable after such expiry and shall be further readjusted in such manner upon the expiry of any further such right.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) If and whenever, at any time after the date hereof and prior to the Time of Expiry, the Corporation shall
fix a record date for the distribution to all or substantially all of the holders of its outstanding Common Shares of rights, options
or warrants entitling them, for a period expiring not more than 45 days after such record date, to subscribe for or purchase Common Shares,
or securities exchangeable or exercisable for or convertible into Common Shares, at a price per share to the holder (or at an exchange,
exercise or conversion price per share) of less than 95% of the Current Market Price on such record date (any of such events being called
a "**Rights Offering** "), then the Exchange Basis shall be adjusted effective immediately after such record date for the
Rights Offering by multiplying the Exchange Basis in effect immediately prior to such record date by a fraction:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the numerator of which shall be the number of Common Shares which would be outstanding after giving effect
to the Rights Offering (assuming the exercise of all of the rights, options or warrants under the Rights Offering and assuming the exchange,
exercise or conversion into Common Shares of all exchangeable, exercisable or convertible securities issued upon exercise of such rights,
options or warrants, if any), and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the denominator of which shall be the aggregate of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the total number of Common Shares outstanding as of the record date for the Rights Offering, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) a number of Common Shares determined by dividing

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) the amount equal to the aggregate consideration payable on the exercise of all of the rights, options
and warrants under the Rights Offering plus the aggregate consideration, if any, payable on the exchange, exercise or conversion of the
exchangeable or convertible securities issued upon exercise of such rights, options or warrants (assuming the exercise of all rights,
options and warrants under the Rights Offering and assuming the exchange or conversion of all exchangeable or convertible securities issued
upon exercise of such rights, options and warrants);

by

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) the Current Market Price as of the record date for the Rights Offering.

The resulting product, adjusted to the nearest 1/100th, shall thereafter be the Exchange Basis until further adjusted as provided in this Article 3. Any Common Shares owned by or held for the account of the Corporation or any of its Subsidiaries or a partnership in which the Corporation is directly or indirectly a party to will be deemed not to be outstanding for the purposes of any computation. If, at the date of expiry of the rights, options or warrants subject to the Rights Offering, less than all the rights, options or warrants have been exercised, then the Exchange Basis shall be readjusted effective immediately after the date of expiry to the Exchange Basis which would have been in effect on the date of expiry if only the rights, options or warrants issued had been those exercised. If at the date of expiry of the rights of exchange, exercise or conversion of any securities issued pursuant to the Rights Offering less than all of such securities have been exchanged or exercised for, or converted into, Common Shares, then the Exchange Basis shall be readjusted effective immediately after the date of such expiry to the Exchange Basis which would have been in effect on the date of expiry if only the exchangeable, exercisable or convertible securities issued had been those securities actually exchanged or exercised for or converted into Common Shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) If and whenever, at any time after the date hereof and prior to the Time of Expiry, the Corporation shall
fix a record date for the issuance or distribution to all or substantially all the holders of its outstanding Common Shares of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) shares of the Corporation of any class other than Common Shares; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) rights, options or warrants to acquire Common Shares or securities exchangeable or exercisable for or
convertible into Common Shares; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) evidences of indebtedness; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) cash, securities or any property or other assets,

and if such issuance or distribution does not constitute a Common Share Reorganization or a Rights Offering (any of such non-excluded events being herein called a "**Special Distribution**"), the Exchange Basis shall be adjusted effective immediately after the record date for the Special Distribution by multiplying the Exchange Basis in effect on such record date by a fraction:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) the numerator of which shall be the number of Common Shares outstanding on such record date multiplied
by the Current Market Price on such record date, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) the denominator of which shall be:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) the product of the number of Common Shares outstanding on such record date and the Current Market Price
on such record date,

less

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) the fair market value, as determined by action by the board of directors acting reasonably and in good
faith (whose determination shall, absent manifest error, be conclusive), to the holders of the Common Shares of the shares, rights, options,
warrants, evidences of indebtedness or property or other assets issued or distributed in the Special Distribution,

provided that no such adjustment shall be made if the result of such adjustment would be to decrease the Exchange Basis in effect immediately before such record date. The resulting product, adjusted to the nearest 1/100th, shall thereafter be the Exchange Basis until further adjusted as provided in this Article 3. Any Common Shares owned by or held for the account of the Corporation or any of its Subsidiaries or a partnership in which the Corporation is directly or indirectly a party to will be deemed not to be outstanding for the purposes of any computation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) If, at any time while Warrants are outstanding (i) the Corporation effects any merger or consolidation
of the Corporation with or into another person, in which the Corporation is not the surviving entity or the shareholders of the Corporation
immediately prior to such merger or consolidation do not own, directly or indirectly, at least 50% of the voting power of the surviving
entity immediately after such merger or consolidation, (ii) the Corporation effects any sale to another person of all or substantially
all of its assets in one or a series of related transactions, (iii) pursuant to any tender offer or exchange offer (whether by the
Corporation or another person), shareholders who tender shares representing more than 50% of the voting power of the Common Shares and
the Corporation or such other person, as applicable, accepts such tender for payment, (iv) the Corporation consummates a share purchase
agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off, merger or plan of
arrangement) with another person whereby such other person acquires more than the 50% of the voting power of the Common Shares or (v) the
Corporation effects any reclassification of the Common Shares or any compulsory share exchange pursuant to which the Common Shares are
effectively converted into or exchanged for other securities, cash or property (other than as a result of a subdivision or combination
of Common Share covered by Section 3.13(1) above) (in any such case, a "**Fundamental Transaction** "), then following
such Fundamental Transaction the Holder shall have the right to receive, upon exercise of the Warrants, the same amount and kind of securities,
cash, other property or any combination thereof as it would have been entitled to receive upon the occurrence of such Fundamental Transaction
if it had been, immediately prior to such Fundamental Transaction, the holder of the number of Warrant Shares then issuable upon exercise
in full of the Warrants without regard to any limitations on exercise contained herein (the "**Alternate Consideration** ").
Notwithstanding anything to the contrary, in the event of a Fundamental Transaction, the Corporation or any successor company (as defined
below) shall, at the Holder's option, exercisable at any time concurrently with, or within 30 days after, the consummation of the
Fundamental Transaction (or, if later, the date of the public announcement of the applicable Fundamental Transaction), purchase the Warrants
from the Holder by paying to the Holder an amount of cash equal to the Black Scholes Value (as defined below) of the remaining unexercised
portion of the Warrants on the date of the consummation of such Fundamental Transaction; provided, however, that, (A) prior written
approval of the TSXV is obtained should the Corporation or a successor company remain listed on the TSXV further to the consummation of
the Fundamental Transaction and (B) if the Fundamental Transaction is not within the Corporation's control, including not approved
by the Corporation's Board of Directors, a Holder shall only be entitled to receive from the Corporation or any successor company, as
of the date of consummation of such Fundamental Transaction, the same type or form of consideration (and in the same proportion), at the
Black Scholes Value of the unexercised portion of the Warrants, that is being offered and paid to the holders of Common Shares in connection
with the Fundamental Transaction, whether that consideration be in the form of securities, cash, other property or any combination thereof,
or whether the holders of Common Shares are given the choice to receive from among alternative forms of consideration in connection with
the Fundamental Transaction. "**Black Scholes Value**" means the value of the Warrants based on the Black-Scholes Option
Pricing Model obtained from the "**OV**" function on Bloomberg, L.P. ()"**Bloomberg**") determined as of
the day of consummation of the applicable Fundamental Transaction for pricing purposes and reflecting (A) a risk-free interest rate
corresponding to the U.S. Treasury rate for a period equal to the time between the date of the public announcement of the applicable Fundamental
Transaction and the Time of Expiry, (B) an expected volatility equal to the greater of 100% and the 100 day volatility obtained from
the HVT function on Bloomberg (determined utilizing a 365 day annualization factor) as of the trading day immediately following the public
announcement of the applicable Fundamental Transaction, (C) the underlying price per share used in such calculation shall be the
greater of (i) the sum of the price per share being offered in cash, if any, plus the value of any non-cash consideration, if any,
being offered in such Fundamental Transaction and (ii) the greater of (x) the last Current Market Price immediately prior to
the public announcement of such Fundamental Transaction and (y) the last Current Market Price immediately prior to the consummation
of such Fundamental Transaction and (D) a remaining option time equal to the time between the date of the public announcement of
the applicable Fundamental Transaction and the Time of Expiry and (E) a zero cost of borrow. The payment of the Black Scholes Value
will be made by wire transfer of immediately available funds (or such other consideration) within five Business Days of the Holder's
election (or, if later, on the effective date of the Fundamental Transaction). The Corporation shall cause any successor company in a
Fundamental Transaction in which the Corporation is not the survivor to assume in writing all of the obligations of the Corporation under
the Warrants in accordance with the provisions of this Section 3.13(4) pursuant to written agreements in form and substance
reasonably satisfactory to the Holder prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the Holder
in exchange for the Warrants a security of the successor company evidenced by a written instrument substantially similar in form and substance
to the Warrants which is exercisable for a corresponding number of shares of such successor company (or its parent entity) equivalent
to the Common Share acquirable and receivable upon exercise of the Warrants (without regard to any limitations on the exercise of the
Warrants) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares
(but taking into account the relative value of the Common Share pursuant to such Fundamental Transaction and the value of such shares,
such number of shares and such exercise price being for the purpose of protecting the economic value of the Warrant immediately prior
to the consummation of such Fundamental Transaction).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) Any adjustment to the Exchange Basis as set forth herein shall also include a corresponding adjustment
to the Exercise Price which shall be calculated by multiplying the Exercise Price by a fraction: (a) the numerator of which shall
be the Exchange Basis prior to the adjustment, and (b) the denominator of which shall be the Exchange Basis after the adjustment.

**3.14** **Rules Regarding Calculation of Adjustment of Exchange Basis** 

For the purposes of Section 3.13:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) The adjustments provided for in Section 3.13 shall be cumulative and such adjustments shall be made
successively whenever an event referred to in Section 3.13 shall occur, subject to the following subsections of this Section 3.14.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) No adjustment in the: (a) Exchange Basis shall be required unless such adjustment would result in
a change of at least 0.01 of a Warrant Share based on the prevailing Exchange Basis; or (b) Exercise Price shall be required unless
such adjustment would result in a change of at least 1%, provided that any adjustments which, except for the provisions of this subsection,
would otherwise have been required to be made, shall be carried forward and taken into account in any subsequent adjustment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) No adjustment in the Exchange Basis shall be made in respect of any event described in Section 3.13,
other than the events referred to in paragraphs (ii) and (iii) of subsection (1) thereof, if Warrantholders are entitled
to participate in such event on the same terms, mutatis mutandis, as if Warrantholders had exercised their Warrants prior to or on the
effective date or record date of such event, any such participation being subject to regulatory approval.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) No adjustment in the Exchange Basis shall be made pursuant to Section 3.13 in respect of the issue
from time to time of Warrant Shares purchasable on exercise of the Warrants or pursuant to the exercise, conversion or exchange of securities
of the Corporation outstanding as of the date hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) The Corporation shall from time to time immediately after the occurrence of any event which requires an
adjustment or readjustment as provided in Section 3.13, deliver a certificate of the Corporation to the Warrant Agent specifying
the nature of the event requiring the same and the amount of the adjustment or readjustment necessitated thereby and setting forth in
reasonable detail the method of calculation and the facts upon which such calculation is based, which certificate shall be supported by
a certificate of the Corporation's Auditors verifying such calculation. The Warrant Agent shall rely, and shall be protected in so doing,
upon the certificate of the Corporation or of the Corporation's Auditor and any other document filed by the Corporation pursuant to this
Section 3.14 for all purposes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) If a dispute shall at any time arise with respect to adjustments provided for in Section 3.13, such
dispute shall, absent manifest error, be conclusively determined by the Corporation's Auditors, or if they are unable or unwilling
to act, by such other firm of independent chartered professional accountants as may be selected by the directors and any further determination,
absent manifest error, shall be binding upon the Corporation, the Warrant Agent and the Warrantholders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) If the Corporation shall set a record date to determine the holders of the Common Shares for the purpose
of entitling them to receive any dividend or distribution or any subscription or purchase rights and shall, thereafter and before the
distribution to such shareholders of any such dividend, distribution, or subscription or purchase rights, legally abandon its plan to
pay or deliver such dividend, distribution, or subscription or purchase rights, then no adjustment in the Exchange Basis shall be required
by reason of the setting of such record date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(8) In the absence of a resolution of the directors fixing a record date for a Rights Offering or Special
Distribution, the Corporation shall be deemed to have fixed as the record date therefor the date on which the Rights Offering or Special
Distribution is effected.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(9) If the purchase price provided for in any Rights Offering (the "**Rights Offering Price** ")
is decreased, the Exchange Basis shall forthwith be changed so as to increase the Exchange Basis to such Exchange Basis as would have
been obtained had the adjustment to the Exchange Basis made pursuant to subsection 3.13(2) upon the issuance of such Rights Offering
been made upon the basis of the Rights Offering Price as so decreased, provided that the provisions of this subsection shall not apply
to any decrease in the Rights Offering Price resulting from provisions in any such Rights Offering designed to prevent dilution if the
event giving rise to such decrease in the Rights Offering Price itself requires an adjustment to the Exchange Basis pursuant to the provisions
of Section 3.13.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(10) As a condition precedent to the taking of any action that would require any adjustment in any of the subscription
rights pursuant to any of the Warrants, including the Exchange Basis, the Corporation shall take any corporate action which may, in the
opinion of counsel, be necessary in order that 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 that all the holders of such Warrants are entitled to
receive on the exercise of all the subscription rights attaching thereto in accordance with the provisions thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(11) The Warrant Agent shall be entitled to act and rely on any adjustment calculations by the Corporation
or the Corporation's Auditors.

**3.15** **Postponement of Subscription** 

In any case where the application of Section 3.13 results in an increase in the number of Common Shares that are issuable upon exercise of the Warrants taking effect immediately after the record date for a specific event, if any Warrant is exercised after that record date and prior to completion of such specific event, the Corporation may postpone the issuance to the Warrantholder of the Warrant Shares to which he is entitled by reason of such adjustment, but such Warrant Shares shall be so issued and delivered to that holder upon completion of that event, with the number of such Warrant Shares calculated on the basis of the number of Warrant Shares on the date that the Warrant was exercised, adjusted for completion of that event and the Corporation shall deliver to the person or persons in whose name or names the Warrant Shares are to be issued an appropriate instrument evidencing the right of such person or persons to receive such Warrant Shares and the right to receive any dividends or other distributions which, but for the provisions of this Section 3.15, such person or persons would have been entitled to receive in respect of such Warrant Shares from and after the date that the Warrant was exercised in respect thereof.

**3.16** **Notice of Adjustment** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) At least 14 days prior to the effective date or record date, as the case may be, of any event which requires
or might require adjustment pursuant to Section 3.13, the Corporation shall:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) file with the Warrant Agent a certificate of the Corporation specifying the particulars of such event
(including the record date or the effective date for such event) and, if determinable, the required adjustment and the computation of
such adjustment and the facts upon which such calculation is based, which certificate may be supported by a certificate of the Corporation's
Auditors verifying such calculation if requested by the Warrant Agent at their discretion and the Warrant Agent shall rely, and shall
be protected in so doing, upon the certificate of the Corporation or of the Corporation's Auditor and any other document filed by
the Corporation pursuant to this Article 3 for all purposes; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) give notice to the Warrantholders of the particulars of such event (including the record date or the effective
date for such event) and, if determinable, the required adjustment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) In case any adjustment for which a notice in subsection 3.16(1) has been given is not then determinable,
the Corporation shall promptly after such adjustment is determinable:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) file with the Warrant Agent a computation of such adjustment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) give notice to the Warrantholders of the adjustment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) The Warrant Agent may, absent manifest error, act and rely, and shall be protected in so acting and relying,
upon certificates and other documents filed by the Corporation pursuant to this Section 3.16 for all purposes of the adjustment.

**3.17** **No Action after Notice** 

The Corporation covenants with the Warrant Agent that it will not take any other corporate action which might deprive a Warrantholder of the opportunity of exercising the rights of acquisition pursuant thereto during the period of 10 Business Day after the giving of the notice set forth in subsection 3.16(1) and subsection 3.16(2)(b).

**3.18** **Optional Purchases by the Corporation** 

Subject to applicable law and prior approval of the TSX or Nasdaq, if required, the Corporation may from time to time purchase on any stock exchange (if then listed), in the open market, by private agreement or otherwise any of the Warrants. Any such purchase shall be made at the lowest price or prices at which, in the opinion of the board of directors of the Corporation, such Warrants are then obtainable, plus reasonable costs of purchase, and may be made in such manner, from such persons, and on such other terms as the Corporation in its sole discretion may determine. The Warrant Certificates representing the Warrants purchased pursuant to this Section 3.18 shall forthwith be delivered to and cancelled by the Warrant Agent.

**3.19** **Protection of Warrant Agent** 

The Warrant Agent shall not:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) at any time be under any duty or responsibility to any Warrantholder to determine whether any facts exist
that may require any adjustment contemplated by this Article 3, nor to verify the nature and extent of any such adjustment when made
or the method employed in making the same;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) be accountable with respect to the validity or value or the kind or amount of any Warrant Shares or of
any other securities or property that may at any time be issued or delivered upon the exercise of the rights attaching to any Warrants;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) be responsible for any failure of the Corporation to issue, transfer or deliver Warrant Shares or certificates
for the same, or make any cash payment, upon the surrender of any Warrants for the purpose of the exercise of such rights or to comply
with any of the covenants contained in this Article 3; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) incur any liability or responsibility whatsoever or be in any way responsible for the consequences of
any breach on the part of the Corporation of any of the representations, warranties or covenants of the Corporation herein contained or
any acts or deeds of the directors, officers, employees, agents or servants of the Corporation.

**Article 4<br> EXERCISE OF WARRANTS**

**4.1** **Method of Exercise of Warrants** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) The registered holder of any Warrant may exercise the rights thereby conferred on him to acquire all or
any part of the Warrant Shares to which such Warrant entitles the holder, by surrendering the Warrant Certificate representing such Warrants
to the Warrant Agent at any time prior to the Time of Expiry at the Warrant Agency, with a duly completed and executed exercise form (the
 "**Exercise Form**") of the registered holder or his executors, administrators or other legal representative or his attorney
duly appointed by an instrument in writing in the form and manner satisfactory to the Warrant Agent, substantially in the form endorsed
on the Warrant Certificate as Schedule "A", specifying the number of Warrant Shares subscribed for together with a certified
cheque, bank draft or money order in lawful money of the United States, payable to or to the order of the Corporation in an amount equal
to the Exercise Price multiplied by the number of Warrant Shares subscribed for. A Warrant Certificate with the duly completed and executed
Exercise Form and payment of the Exercise Price shall be deemed to be surrendered only upon personal delivery thereof to or, if sent
by mail or other means of transmission, upon actual receipt thereof by the Warrant Agent. The Exercise Form shall be signed by the
Warrantholder, or his executors, or administrators or other legal representative or his attorney duly appointed by an instrument in writing
in the form and manner satisfactory to the Warrant Agent, shall specify the person(s) in whose name such Warrant Shares are to be
issued, the address(es) of such person(s) and the number of Warrant Shares to be issued to each person, if more than one is so specified.
If any of the Warrant Shares subscribed for are to be issued to (a) person(s) other than the Warrantholder, the signatures set
out in the Exercise Form shall be guaranteed by a Canadian Schedule I chartered bank or a medallion signature guarantee from a member
of a recognized Signature Medallion Guarantee Program and (b) the Warrantholder shall pay to the Corporation or the Warrant Agent
all applicable transfer or similar taxes and the Corporation shall not be required to issue or deliver certificates evidencing Warrant
Shares unless or until such Warrantholder shall have paid to the Corporation or the Warrant Agent on behalf of the Corporation the amount
of such tax or shall have established to the reasonable satisfaction of the Corporation that such tax has been paid or that no tax is
due.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) If, at the time of exercise of the Warrants, in accordance with the provisions of subsections 4.1(1) or
4.1(3), there are any trading restrictions on the Warrant Shares pursuant to Securities Laws or stock exchange requirements, the Corporation
shall, on the advice of counsel, endorse any certificates or book-entry positions representing the Warrant Shares to such effect. The
Warrant Agent is entitled to assume compliance with all Securities Laws unless otherwise notified in writing by the Corporation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) A Beneficial Owner of Uncertificated Warrant evidenced by a security entitlement in respect of Warrants
in the Book-Based System who desires to exercise his Uncertificated Warrants, must do so by causing a Depository Participant to deliver
to the Depository (at its office in the City of Toronto, or New York, as applicable), on behalf of the Beneficial Owner at any time prior
to the Time of Expiry, a written notice of the Beneficial Owner's intention to exercise Warrants (the "**Exercise Notice** ")
in a manner acceptable to the Depository. Forthwith upon receipt by the Depository of such notice, as well as payment for the aggregate
Exercise Price, the Depository shall deliver to the Warrant Agent confirmation of its intention to exercise Warrants (the "**Confirmation** ")
in a manner acceptable to the Warrant Agent, including by electronic means through the Book-Based System. The Beneficial Owner will initiate
the electronic exercise through the Book-Based System, by way of the Confirmation and forward the aggregate Exercise Price electronically
to the Warrant Agent and the Warrant Agent will execute the exercise by issuing to the Depository through the Book-Based System the Warrant
Shares to which the exercising Beneficial Owner is entitled pursuant to the exercise. Any expense associated with the preparation and
delivery of Exercise Notices will be for the account of the Beneficial Owner exercising the Warrants and the Warrant Agent will execute
the exercise by issuing to the Depository through the Book-Based System the Warrant Shares to which the exercising Warrantholder is entitled
pursuant to the exercise. Any expense associated with the exercise process will be for the account of the entitlement holder exercising
the Warrants and/or the Depository Participant exercising the Warrants on its behalf. Issuance of Warrant Shares shall be made without
charge to the Holder for any expense or fee of the Warrant Agent and transfer agent in respect of the issuance of such Warrant Shares,
which expenses and fees shall be paid by the Corporation. Solely for purposes of Canadian Universal Market Rules and Regulation SHO,
the Beneficial Owner shall be deemed to have exercised Warrants upon the delivery to its Depository Participant of irrevocable instructions
to exercise the Warrants and pay their exercise price.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) By causing a Depository Participant to deliver notice to the Depository, a Beneficial Owner shall be deemed
to have irrevocably surrendered his Warrants so exercised and appointed such Depository Participant to act as his or her exclusive settlement
agent with respect to the exercise and the receipt of Warrant Shares in connection with the obligations arising from such exercise.

Any notice which the Depository determines to be incomplete, not in proper form or not duly executed shall for all purposes be void and of no effect and the exercise to which it relates shall be considered for all purposes not to have been exercised thereby. A failure by a Depository Participant to exercise or to give effect to the settlement thereof in accordance with the Beneficial Owner's instructions will not give rise to any obligations or liability on the part of the Corporation or Warrant Agent to the Depository Participant or the Beneficial Owner.

If the Exercise Form set forth in the Warrant Certificate shall have been amended, the Corporation shall cause the amended Exercise Form to be forwarded to all registered Warrantholders.

Exercise Forms and Confirmations must be delivered to the Warrant Agent at any time during the Warrant Agent's actual business hours on any Business Day prior to the Expiry Time. Any Exercise Form or Confirmations received by the Warrant Agent after business hours on any Business Day other than the Expiry Date will be deemed to have been received by the Warrant Agent on the next following Business Day.

Any Warrant with respect to which a Confirmation or Exercise Form is not received by the Warrant Agent before the Expiry Time shall be deemed to have expired and become void and all rights with respect to such Warrants shall terminate and be cancelled.

**4.2** **[Reserved]** 

**4.3** **No Fractional Warrant Shares** 

Under no circumstances shall the Corporation be obliged to issue any fractional Warrant Shares or any cash or other consideration in lieu thereof upon the exercise of one or more Warrants. To the extent that the holder of one or more Warrants would otherwise have been entitled to receive on the exercise or partial exercise thereof a fraction of a Warrant Share, that holder may exercise that right in respect of the fraction only in combination with another Warrant or Warrants that in the aggregate entitle the holder to purchase a whole number of Warrant Shares; otherwise fractional Warrant Shares shall be rounded down to the nearest whole number of Warrant Shares without compensation therefor.

**4.4** **Effect of Exercise of Warrants** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Upon compliance by the Warrantholder with the provisions of Section 4.1, the Warrant Shares subscribed
for shall be deemed to have been issued and the person to whom such Warrant Shares are to be issued shall be deemed to have become the
holder of record of such Warrant Shares on the Exercise Date unless the transfer registers of the Corporation for the Common Shares shall
be closed on such date, in which case the Warrant Shares subscribed for shall be deemed to have been issued and such person shall be deemed
to have become the holder of record of such Warrant Shares on the date on which such transfer registers are reopened.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Within two Business Days following the due exercise of a Warrant pursuant to Section 4.1 and forthwith
after the Time of Expiry, the Warrant Agent shall deliver to the Corporation a notice setting forth the particulars of all Warrants exercised,
if any, and the persons in whose names the Warrant Shares are to be issued (as applicable) and the addresses of such holders of the Warrant
Shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Within two Business Days of the due exercise of a Warrant pursuant to Section 4.1 (the "**Share Delivery Date** "), the Corporation shall cause the Transfer Agent to issue, on or prior to the Share Delivery Date, to the Depository
through the Book-Based System the Warrant Shares to which the exercising Warrantholder is entitled pursuant to the exercise or mail (or
email) to the person in whose name the Warrant Shares so subscribed for are to be issued, as specified in the Exercise Form completed
on the Warrant Certificate, at the address (or email address) specified in the Exercise Form, a certificate or certificates, or other
satisfactory evidence, including confirmation of registration in the direct registration system of the Transfer Agent, for the Warrant
Shares to which the Warrantholder is entitled and, if applicable, shall cause the Warrant Agent to mail a Warrant Certificate representing
any Warrants not then exercised. The Warrant Agent will not be liable to the Corporation for any payment made by the Corporation under
Section 4.4(5) of this Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) If the Corporation fails to cause the Warrant Agent to deliver to the Warrantholder the Warrant Shares
issuable pursuant to Section 4.4(3) by the Share Delivery Date, then the Warrantholder will have the right to rescind such exercise.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) In addition to any other rights available to a Warrantholder, if the Corporation fails to cause the Warrant
Agent to deliver to the Warrantholder the Common Shares issuable in accordance with Section 4.4(3) pursuant to an exercise on
or before the Share Delivery Date and, if after such date, the Warrantholder is required by its broker to purchase (in an open market
transaction or otherwise) or the Warrantholder's brokerage firm otherwise purchases, Common Shares to deliver in satisfaction of
a sale by the Warrantholder of the Warrant Shares that the Warrantholder anticipated receiving upon such exercise (a "**Buy-In** "),
then the Corporation shall (A) pay in cash to the Warrantholder the amount, if any, by which (x) the Warrantholder's total
purchase price (including brokerage commissions, if any) for the Common Shares so purchased exceeds (y) the amount obtained by multiplying
(1) the number of Common Shares that the Corporation was required to deliver to the Warrantholder in connection with the exercise
at issue, times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the option
of the Warrantholder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was
not honoured (in which case such exercise shall be deemed rescinded) or deliver to the Warrantholder the number of Common Shares that
would have been issued had the Corporation timely complied with its delivery obligations under Section 4.4(3). For example, if the
Warrantholder purchases Common Shares having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise
of Common Shares with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (A) of the immediately
preceding sentence, the Corporation shall be required to pay to the Warrantholder $1,000. In addition, if the Warrantholder incurs any
fees and expenses (including those charged by CDS) because of the Corporation's failure to cause the Warrant Agent to deliver to
the Warrantholder on or before the Share Delivery Date the Common Shares issuable in accordance with Section 4.4(3) pursuant
to an exercise (the "Late Fees"), the Corporation shall promptly reimburse the Warrantholder for any and all such Late Fees.
The Warrantholder shall provide the Corporation written notice indicating the amounts payable to the Warrantholder in respect of the Buy-In
and/or Late Fees and, upon request of the Corporation, evidence of the amount of such loss. Nothing herein shall limit a Warrantholder's
right to pursue any other remedies available to it under this Indenture, at law or in equity including, without limitation, a decree of
specific performance and/or injunctive relief with respect to the Corporation's failure to timely deliver Warrant Shares as required
under Section 4.4(3) following the valid exercise of Warrants under this Indenture.

**4.5** **Cancellation of Warrants** 

All Warrants surrendered to the Warrant Agent pursuant to Sections 3.7, 3.8(3), 3.10, 3.18 or 4.1 shall be cancelled by the Warrant Agent and the Warrant Agent shall record the cancellation of such Warrants on the register of holders maintained by the Warrant Agent pursuant to subsection 3.8(1). The Warrant Agent shall, if required by the Corporation, furnish the Corporation with a certificate identifying the Warrants so cancelled. All Warrants that have been duly cancelled shall be without further force or effect whatsoever.

**4.6** **Subscription for less than Entitlement** 

The holder of any Warrant may subscribe for and purchase a whole number of Warrant Shares that is less than the number that the holder is entitled to purchase pursuant to a surrendered Warrant. In such event, the holder thereof shall be entitled to receive a new Warrant Certificate, if applicable, in respect of the balance of Warrants that were not then exercised.

**4.7** **Expiration of Warrant** 

After the Time of Expiry, all rights under any Warrant in respect of which the right of subscription and purchase herein and therein provided for shall not theretofore have been exercised shall wholly cease and terminate and such Warrant shall be void and of no effect.

**4.8** **U.S. Securities Law Matters** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) The Corporation has agreed to file with the SEC, a prospectus supplement to a base shelf prospectus included
in a registration statement (or a prospectus supplement to an effective shelf registration statement the "**Registration Statement** ")
registering the resale of all of the Warrant Shares and to have the Registration Statement declared effective within the time period set
forth in that certain Subscription Agreement dated as of February 7, 2023. All expenses incidental to the Corporation's performance
of or compliance with the foregoing provisions will be borne by the Corporation, including, without limitation: (i) all registration
and filing fees and expenses; (ii) all fees and expenses of compliance with federal securities and state Blue Sky securities laws;
(iii) all fees and disbursements of counsel for the Corporation, independent certified public accountants of the Corporation and
technical experts retained by the Corporation whose consent is required to be provided with respect to any Registration Statement.

The Warrants may only be exercised by persons who establish to the reasonable satisfaction of the Corporation and the Warrant Agent that the issuance of the Warrant Shares pursuant to the exercise of the Warrants can be completed pursuant to and in accordance with an exemption or exclusion from the registration requirements of the *U.S. Securities Act* and all applicable state securities laws. If required by the Warrant Agent, the Corporation shall cause its counsel, or counsel acceptable to the Warrant Agent, to issue to the Warrant Agent within two Business Days of receipt of a request from a Warrantholder to exercise Warrants at a time when no Registration Statement is effective a legal opinion with respect to the availability of an applicable exemption or exclusion from the registration requirements of the *U.S. Securities Act* and applicable state securities laws, subject to receipt by the Corporation and the Warrant Agent from the Warrantholder of customary representations and other documentation in connection therewith. The Corporation shall be responsible for the fees associated with such opinion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) If any person shall fail to deliver customary representations and other documentation requested by the
Corporation or Warrant Agent pursuant to Section 4.8(1) or if no exemption or exclusion is available in the opinion of the Corporation's
counsel, or counsel acceptable to the Warrant Agent, the holder of the applicable Warrant shall be notified by the Warrant Agent within
two Business Days that the evidence provided has been deemed insufficient to permit the exercise of such Warrant and providing a description
of the nature of such deficiency. In the case where the Corporation is not satisfied with the provided evidence, it shall furnish to the
Warrant Agent either (i) the form of proper notice to be delivered to establish the required evidence or (ii) a description
of the deficiency. Until such time as the Corporation or Warrant Agent, as the case may be, acting reasonably, is satisfied with the evidence
provided, the holder of the Warrant shall not be permitted to exercise the Warrant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) The Corporation will notify the Warrant Agent when a Registration Statement becomes effective under the *U.S. Securities Act* and the Warrant Agent will notify the registered holder of Warrants as required. Thereafter, the Warrant Agent
may assume that a Registration Statement remains effective until otherwise notified in writing by the Corporation that such Registration
Statement is no longer effective. The Corporation shall at all times be obligated to provide prompt notice to the Warrant Agent regarding
any change in the effectiveness of a Registration Statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) If Applicable: Notwithstanding any provisions herein, a beneficial owner of Warrants issued in uncertificated
form evidenced by a security entitlement in respect of Warrants in a book entry registration system who desires to exercise his or her
Warrants must do so by causing a DTC Participant to deliver to DTC on behalf of the entitlement holder, an irrevocable notice of the owner's
intention to exercise Warrants in a manner acceptable to DTC prior to the Time of Expiry. Forthwith upon receipt by DTC of such notice,
DTC shall be delivered forthwith to the Warrant Co-Agent. Upon receipt by the Warrant Co-Agent such notice and the aggregate Exercise
Price of the Warrants, which may be delivered up to four (4) Business Days after the Time of Expiry, the Warrant Co-Agent shall issue
the resulting shares.

**4.9** **Securities Restrictions** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Warrant Certificates originally issued to, or for the benefit or account of, a person in the United States
and each Warrant Certificate issued in exchange therefor or in substitution thereof shall bear or be deemed to bear the following legends
or such variations thereof as the Corporation may prescribe from time to time:

"THIS SECURITY AND THE COMMON STOCK, IF ANY, ISSUABLE UPON EXERCISE OF THIS SECURITY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER: (1) REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A "QUALIFIED INSTITUTIONAL BUYER" (WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND (2) AGREES FOR THE BENEFIT OF ELECTRA BATTERY MATERIALS CORPORATION (THE "COMPANY") THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL ISSUE DATE HEREOF OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR. PROVISION THERETO AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT: (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR (B) OUTSIDE THE UNITED STATES PURSUANT TO REGULATION S UNDER THE SECURITIES ACT AND IN COMPLIANCE WITH APPLICABLE LOCAL LAWS AND REGULATIONS, OR (C) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR (D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH CLAUSE (2)(B) or (D) ABOVE, THE COMPANY AND THE WARRANT AGENT RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE SATISFACTORY TO EACH OF THEM IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) The Warrant Agent shall be entitled to assume that Warrant Shares will be issued pursuant to the exercise
of any Warrant in compliance with the Securities Laws of all applicable jurisdictions and without legending any certificate representing
the Warrant Shares unless the Warrant Agent has received notice in writing from the Corporation stating otherwise and setting forth the
restrictions on the exercise of the Warrants and any legend the certificates representing the Warrant Shares should bear. No duty shall
rest with the Warrant Agent to determine compliance of any Warrant with applicable Securities Laws.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Neither the Corporation nor the Warrant Agent shall effect any exercise of a Warrant, and a Warrantholder
shall not have the right to exercise any portion of a Warrant, pursuant to Article 4 or otherwise, to the extent that, after giving
effect to such issuance after exercise as set forth on the Exercise Form, the Warrantholder (and with respect to any Warrantholder, collectively,
any such Warrantholder's affiliates, any persons or entities acting as a "**group**" together with such Warrantholder
with respect to the Common Shares for purposes of Section 13(d) of the *Exchange Act*, and any other Persons whose beneficial
ownership of the Common Shares would be aggregated with such Warrantholder 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 Warrantholder 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 Warrantholder 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 Equity Share
equivalents), subject to a limitation on conversion or exercise analogous to the limitation contained herein, beneficially owned by the
Warrantholder or any of its Attribution Parties. Except as set forth in the preceding sentence, for purposes of this Section 4.9(2),
beneficial ownership shall be calculated in accordance with Section 13(d) of the *U.S. Exchange Act* and the rules and
regulations promulgated thereunder, it being acknowledged by the Warrantholder that neither the Warrant Agent nor the Corporation is representing
to the Warrantholder that such calculation is in compliance with Section 13(d) of the *U.S. Exchange Act* and the Warrantholder
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 4.9(2) applies, the determination of whether a Warrant is exercisable (in relation
to other securities owned by the Warrantholder 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 Warrantholder, and the submission of an Exercise Form shall
be deemed to be the Warrantholder's determination of whether a Warrant is exercisable (in relation to other securities owned by
the Warrantholder together with any Attribution Parties) and of which portion of a Warrant is exercisable, in each case subject to the
Beneficial Ownership Limitation, and neither the Warrant Agent nor the Corporation shall 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 *U. S. Exchange Act* and the rules and regulations promulgated thereunder. For purposes
of this Section 4.9(2) in determining the number of outstanding Common Shares, a Warrantholder 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
Warrantholder, the Corporation shall, within two trading days, confirm orally and in writing to the Warrantholder 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 Warrantholder 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 4.9(2) 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 4.9(2) shall apply to a successor holder of a Warrant.
For greater certainty, the Warrant Agent will have no responsibility for monitoring the beneficial ownership level of the Common Shares
held by Warrantholders or their Attribution Parties and will have no liability in regards to the determinations made of whether or not
a Warrantholder or their Attribution Parties would become a beneficial holder in excess of the Beneficial Ownership Limitation of the
issued and outstanding Common Shares upon exercise of their Warrants.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) For as long as the shares of Common Shares are listed on the TSXV, but not longer, in the event a Warrantholder
elects a Beneficial Ownership Limitation that could result in the Warrantholder being entitled to receive a number of Common Shares upon
exercise of a Warrant that would result in the Warrantholder becoming an "Insider" (as defined in the TSXV corporate finance
manual, policies and appendices) of the Corporation upon such exercise, then, if the Warrantholder does become entitled to such Common
Shares upon exercise of a Warrant that would result in the Warrantholder becoming an "Insider", such exercise will only become
effective upon the prior approval of a personal information form and satisfactory completion of a background search for that Warrantholder
by the TSXV, or the waiver of such requirement, with respect to that Warrantholder. In addition, for as long as the Common Shares are
listed on the TSXV, but not longer, in the event that such issuance of Common Shares on exercise of a Warrant would "materially affect
control" (as defined in the TSXV) of the Corporation, such issuance will only become effective in accordance with the requirements
of the TSXV.

**Article 5<br> COVENANTS**

**5.1** **General Covenants of the Corporation** 

The Corporation represents, warrants and covenants with the Warrant Agent for the benefit of the Warrant Agent and the Warrantholders that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) The Corporation will at all times, so long as any Warrants remain outstanding, maintain its existence,
unless otherwise inconsistent with the fiduciary duties of the board of directors of the Corporation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) The Corporation is duly authorized to create and issue the Warrants to be issued hereunder and the Warrants,
when issued and Authenticated, will be legal, valid, binding and enforceable obligations of the Corporation. The Corporation will use
reasonable commercial efforts to ensure that all Common Shares outstanding or issuable from time to time (including without limitation
the Common Shares issuable on the exercise of the Warrants) continue to be or are listed and posted for trading on the TSXV (or such other
Canadian stock exchange acceptable to the Corporation) and the Nasdaq (or such other United States stock exchange acceptable to the Corporation),
and to take all such reasonable steps and actions to do all such reasonable things that may be required to maintain its status as a "**reporting issuer**" not in default of the requirements of Securities Laws where it is or may, from time to time, be a reporting issuer,
provided that the Corporation shall not be required to comply with this Section following the completion of, and this Section shall
not be construed as limiting or restricting the Corporation to agree to, a merger, amalgamation, arrangement, business combination, take-over
bid or like transaction even if the consideration being offered are not securities that are so listed and posted for trading that would
result in the Corporation ceasing to be a reporting issuer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) The Corporation will use reasonable commercial efforts to obtain any approval or consent of the TSXV required
pursuant to Section 3.13(4), including seeking shareholder approval, if required, and in connection with such efforts shall execute,
file and/or deliver, as applicable, all necessary documents, instruments and submissions and take all such other steps as may be necessary
under applicable Securities Laws or TSXV requirements to obtain such approval or consent.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) Subject to Section 3.13, the Corporation will allot and reserve and keep available a sufficient number
of Warrant Shares for issuance upon the exercise of Warrants issued by the Corporation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) The Corporation will cause the Warrant Shares from time to time subscribed for pursuant to the Warrants
issued by the Corporation hereunder, in the manner herein provided, to be duly issued in accordance with the Warrants and the terms hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) The Corporation will cause any certificates representing the Warrant Shares from time to time to be acquired,
pursuant to the Warrants in the manner herein provided, to be duly issued and delivered in accordance with the Warrants and the terms
hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) All Warrant Shares that shall be issued by the Corporation upon exercise of the rights provided for herein
shall be issued as fully paid and non-assessable Common Shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(8) The Corporation will perform and carry out all of the acts or things to be done by it as provided in this
Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(9) The Corporation will use its commercially reasonable efforts to cause the Warrant Agent to keep open the
register of Warrantholders during the Warrant Agent's regular business hours and will not take any action or omit to take any action
which would have the effect of preventing the Warrantholders from receiving any of the Warrant Shares issuable upon exercise of the Warrants.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(10) The Corporation will promptly notify the Warrant Agent and the Warrantholders in writing of any default
under the terms of this Indenture which remains unrectified for more than 10 Business Days following its occurrence.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(11) Provided that the Common Shares are not listed and posting for trading on the TSXV, then, if a Warrant
Exchange Event occurs, the Company shall make an offer to exchange with the Warrantholders all the outstanding Warrants for new securities
that are substantially identical to the Warrants, except that, subject to the rules of any applicable stock exchange on which the
Company's shares are listed from time to time, the term of the new securities shall be five years from the date of issue of the
new securities and the exercise price of the new securities shall be a price equal to a 17.5% premium to the Daily VWAP on the date of
such exchange; provided that under no circumstance may the exercise price of the new securities be less than the greater of $0.60 per
Common Share or the minimum price permitted by the TSXV, if applicable, or more than the Exercise Price, which exchange shall be completed
on or before a date 35 days following the occurrence of the Warrant Exchange Event. For additional clarity and the avoidance of doubt,
the warrant exchange right will never be operable for as long as the Company remains listed on TSXV.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(12) The Company covenants and agrees that, if by the date that is the six-month anniversary of the date hereof
the Daily VWAP of the Common Shares for the 20 consecutive trading days immediately prior to such date is less than 85.0% of the Reference
Price, or the Company has not secured additional investment of at least US$10 million through a sale of Common Shares, then the Company
shall either obtain approval of the TSXV to implement the exchange contemplated by Section 5.1(11) above or de-list the Common Shares
from trading on TSXV and immediately, without any intervening trading dates, re-list the Common Shares on an alternate securities exchange
in Canada such that as a result, the exchange contemplated by Section 5.1(11) above may be consummated. Warrantholders with a majority
of the principal amount of outstanding Warrants may, by notice to the Warrant Agent object to any such alternate securities exchange other
than The Toronto Stock Exchange, the Neo Exchange Inc., or the Canadian Securities Exchange.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(13) Each Holder agrees that it will not, during the period commencing on the date that is 20 trading days
prior to the eight month anniversary of the date hereof and ending on the eight month anniversary of the date hereof, (i) lend, offer,
pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right
or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any Common Shares; or (ii) enter into any swap,
derivative transaction or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership
of Common Shares whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of shares of
Common Shares or other securities, in cash or otherwise provided that, for the avoidance of doubt, the unwinding of any transaction listed
in clauses (i) through (iii) above or the continuation of any such transaction previously initiated during the 20 trading days
prior to the eight month anniversary of the date hereof shall not be prohibited by this clause (13).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(14) For additional clarity and the avoidance of doubt, for as long as the Common Shares are listed on the
TSXV, but not longer, section 5.1(11) shall be inoperable such that the Company may not make the offer described therein.

**5.2** **Securities Qualification Requirements** 

If, in the opinion of counsel, any instrument is required to be filed with, or any permission, order or ruling is required to be obtained from, any securities regulatory authority or any other step is required under any federal or provincial law of Canada before the Warrant Shares may be issued or delivered to a Warrantholder, the Corporation covenants that it will use its commercially reasonable efforts to file such instrument, obtain such permission, order or ruling or take all such other actions, at its expense, as is required or appropriate in the circumstances.

**5.3** **Warrant Agent's Remuneration and Expenses** 

The Corporation covenants that it will pay to the Warrant Agent from time to time reasonable remuneration for its services hereunder and will pay or reimburse the Warrant Agent upon its request for all reasonable expenses and disbursements of and advancements incurred or made by the Warrant Agent in the administration or execution of the duties and obligations hereby created (including the reasonable compensation and the disbursements of its counsel and all other advisers, experts, accountants and assistants not regularly in its employ) both before any default hereunder and thereafter until all duties of the Warrant Agent hereunder shall be finally and fully performed. Any amount owing hereunder and remaining unpaid after 30 days from the invoice date will bear interest at the then current rate charged by the Warrant Agent against unpaid invoices and shall be payable upon demand. This Section shall survive the resignation or removal of the Warrant Agent and/or the termination of this Indenture.

**5.4** **Performance of Covenants by Warrant Agent** 

Subject to Section 9.7, if the Corporation shall fail to perform any of its covenants contained in this Indenture, the Corporation will notify the Warrant Agent in writing of such failure, and if the Corporation has not rectified such failure within 10 Business Days after sending written notice to the Warrant Agent of such failure, the Warrant Agent may notify the Warrantholders of such failure on the part of the Corporation and may itself perform any of the said covenants capable of being performed by it, but shall be under no obligation to perform said covenants or to notify the Warrantholders of such performance by it. All reasonable sums expended, advanced or disbursed by the Warrant Agent in so doing shall be repayable as provided in Section 5.3. No such performance, expenditure or advance by the Warrant Agent shall be deemed to relieve the Corporation of any default hereunder or of its continuing obligations under the covenants herein contained.

**Article 6<br> ENFORCEMENT**

**6.1** **Suits by Warrantholders** 

Subject to Section 7.10, all or any of the rights conferred upon a Warrantholder by the terms of the Warrants held by him and/or this Indenture may be enforced by such Warrantholder by appropriate legal proceedings but without prejudice to the right that is hereby conferred upon the Warrant Agent to proceed in its own name to enforce each and all of the provisions herein contained for the benefit of the holders of the Warrants from time to time outstanding.

**6.2** **Suits by the Corporation** 

The Corporation shall have the right to enforce full payment of the aggregate Exercise Price of all Warrant Shares issued by the Warrant Agent to a Registered Warrantholder hereunder and shall be entitled to demand such payment from the Registered Warrantholder or alternatively to instruct the Warrant Agent to cancel the Warrant Certificates or Uncertificated Warrants, as applicable, and amend the Warrant register accordingly.

**6.3** **Limitation of Liability** 

The obligations hereunder (including without limitation under subsection 9.7(5) are not personally binding upon, nor shall resort hereunder be had to, the private property of any of the past, present or future directors or shareholders of the Corporation or any of the past, present or future officers, employees or agents of the Corporation, and only the property of the Corporation (or any successor person) shall be bound in respect hereof.

**Article 7<br> MEETINGS OF WARRANTHOLDERS**

**7.1** **Right to Convene Meetings** 

The Warrant Agent may at any time and from time to time, and shall on receipt of a written request of the Corporation or of a Warrantholders' Request, convene a meeting of the Warrantholders provided that the Warrant Agent has been provided with sufficient funds and is indemnified to its reasonable satisfaction by the Corporation or by the Warrantholders signing such Warrantholders' Request against the costs, charges, expenses and liabilities that may be incurred in connection with the calling and holding of such meeting. If within 10 Business Days after the receipt of a written request of the Corporation or a Warrantholders' Request, and receipt of funding and indemnity given as aforesaid, the Warrant Agent fails to give the requisite notice specified in Section 7.2 to convene a meeting, the Corporation or such Warrantholders, as the case may be, may convene such meeting. Every such meeting shall be held in the City of Toronto, Ontario or at such other place as may be approved or determined by the Warrant Agent. Any meeting held pursuant to this Article 7 may be done through a virtual or electronic meeting platform, subject to the Warrant Agent's capabilities at the time.

**7.2** **Notice** 

At least 21 days' prior notice of any meeting of Warrantholders shall be given to the Warrantholders at the expense of the Corporation in the manner provided for in Section 10.2 and a copy of such notice shall be delivered to the Warrant Agent unless the meeting has been called by it, and to the Corporation unless the meeting has been called by it.

Such notice shall state the date, time and place of the meeting, the general nature of the business to be transacted and shall contain such information as is reasonably necessary to enable the Warrantholders to make a reasoned decision on the matter, but it shall not be necessary for any such notice to set out the terms of any resolution to be proposed or any of the provisions of this Article 7. The notice convening any such meeting may be signed by an appropriate officer of the Warrant Agent or of the Corporation or the person designated by such Warrantholders, as the case may be.

**7.3** **Chairman** 

The Warrant Agent may nominate in writing an individual (who need not be a Warrantholder) to be chairman of the meeting and if no individual is so nominated, or if the individual so nominated is not present within 15 minutes after the time fixed for the holding of the meeting, the Warrantholders present in person or by proxy shall appoint an individual present to be chairman of the meeting. The chairman of the meeting need not be a Warrantholder.

**7.4** **Quorum** 

Subject to the provisions of Section 7.11, at any meeting of the Warrantholders a quorum shall consist of at least two Warrantholders present in person or represented by proxy and representing at least 20% of the aggregate number of Warrants then outstanding. If a quorum of the Warrantholders shall not be present within one-half hour from the time fixed for holding any meeting, the meeting, if summoned by the Warrantholders or on a Warrantholders' Request, shall be dissolved; but in any other case the meeting shall be adjourned to the same day in the next week (unless such day is not a Business Day in which case it shall be adjourned to the next following Business Day) at the same time and place to the extent possible and, subject to the provisions of Section 7.11, no notice of the adjournment need be given. Any business may be brought before or dealt with at an adjourned meeting that might have been dealt with at the original meeting in accordance with the notice calling the same. At the adjourned meeting the Warrantholders present in person or represented by proxy shall form a quorum and may transact the business for which the meeting was originally convened, notwithstanding that they may not represent at least 20% of the aggregate number of Warrants then unexercised and outstanding. No business shall be transacted at any meeting, except an adjourned meeting as described above, unless a quorum is present at the commencement of business.

**7.5** **Power to Adjourn** 

The chairman of any meeting at which a quorum of the Warrantholders is present may, with the consent of the meeting, adjourn any such meeting, and no notice of such adjournment need be given except such notice, if any, as the meeting may prescribe.

**7.6** **Show of Hands** 

Every question submitted to a meeting shall be decided in the first place by a majority of the votes given on a show of hands except that votes on an extraordinary resolution shall be given in the manner hereinafter provided. At any such meeting, unless a poll is duly demanded as herein provided, a declaration by the chairman that a resolution has been carried or carried unanimously or by a particular majority or lost or not carried by a particular majority shall be conclusive evidence of the fact.

**7.7** **Poll and Voting** 

On every extraordinary resolution, and when demanded by the chairman or by one or more of the Warrantholders acting in person or by proxy on any other question submitted to a meeting and after a vote by show of hands, a poll shall be taken in such manner as the chairman shall direct. Questions other than those required to be determined by extraordinary resolution shall be decided by a majority of the votes cast on the poll. On a show of hands, every person who is present and entitled to vote, whether as a Warrantholder or as proxy for one or more absent Warrantholders, or both, shall have one vote. On a poll, each Warrantholder present in person or represented by a proxy duly appointed by instrument in writing shall be entitled to one vote in respect of each whole Warrant then held by him. A proxy need not be a Warrantholder. The chairman of any meeting shall be entitled, both on a show of hands and on a poll, to vote in respect of the Warrants, if any, held or represented by him.

**7.8** **Regulations** 

Subject to the provisions of this Indenture, the Warrant Agent or the Corporation with the approval of the Warrant Agent may from time to time make and from time to time vary such regulations as it shall consider necessary or appropriate:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) for the deposit of instruments appointing proxies at such place and time as the Warrant Agent, the Corporation
or the Warrantholders convening the meeting, as the case may be, may in the notice convening the meeting direct;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) for the deposit of instruments appointing proxies at some approved place other than the place at which
the meeting is to be held and enabling particulars of such instruments appointing proxies to be mailed or forwarded via facsimile before
the meeting to the Corporation or to the Warrant Agent at the place where the same is to be held and for the voting of proxies so deposited
as though the instruments themselves were produced at the meeting;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) for the form of instrument appointing a proxy and the manner in which the form of proxy may be executed;
and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) generally for the calling of meetings of Warrantholders and the conduct of business thereat including
setting a record date for Warrantholders entitled to receive notice of or to vote at such meeting.

Any regulations so made shall be binding and effective and the votes given in accordance therewith shall be valid and shall be counted. Save as such regulations may provide, the only persons who shall be recognized at any meeting as a Warrantholder, or be entitled to vote or be present at the meeting in respect thereof (subject to Section 7.9), shall be Warrantholders or persons holding proxies of Warrantholders.

**7.9** **Corporation, Warrant Agent and Counsel may be Represented** 

The Corporation, the Warrantholders and the Warrant Agent, by their respective directors, officers and employees and the counsel for each of the Corporation, the Warrantholders and the Warrant Agent may attend any meeting of the Warrantholders and speak thereat but shall not be entitled to vote unless in their capacities as Warrantholders or proxies therefor.

**7.10** **Powers Exercisable by Extraordinary Resolution** 

In addition to all other powers conferred upon them by any other provisions of this Indenture or by law, the Warrantholders at a meeting shall have the power, subject to the TSXV's approval and/or Nasdaq's approval (if applicable), exercisable from time to time by extraordinary resolution:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) to agree to any modification, alteration, compromise or arrangement of the rights of Warrantholders and/or
the Warrant Agent in its capacity as warrant agent hereunder (subject to the Warrant Agent's approval) or on behalf of the Warrantholders
against the Corporation, whether such rights arise under this Indenture or the Warrants or otherwise;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) to amend, modify or repeal any extraordinary resolution previously passed or sanctioned by the Warrantholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) to direct or authorize the Warrant Agent (subject to the Warrant Agent receiving funding and indemnity
to its satisfaction) to enforce any of the covenants on the part of the Corporation contained in this Indenture or the Warrants or to
enforce any of the rights of the Warrantholders in any manner specified in such extraordinary resolution or to refrain from enforcing
any such covenant or right;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) to waive, authorize and direct the Warrant Agent to waive any default on the part of the Corporation in
complying with any provisions of this Indenture or the Warrants either unconditionally or upon any conditions specified in such extraordinary
resolution;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) to restrain any Warrantholder from taking or instituting any suit, action or proceeding against the Corporation
for the enforcement of any of the covenants on the part of the Corporation contained in this Indenture or the Warrants or to enforce any
of the rights of the Warrantholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) to direct any Warrantholder who, as such, has brought any suit, action or proceeding to stay or discontinue
or otherwise deal with any such suit, action or proceeding, upon payment of the costs, charges and expenses reasonably and properly incurred
by such Warrantholder in connection therewith;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) to assent to any change in or omission from the provisions contained in this Indenture or any ancillary
or supplemental instrument which may be agreed to by the Corporation, and to authorize the Warrant Agent to concur in and execute any
ancillary or supplemental indenture embodying the change or omission;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(8) with the consent of the Corporation, such consent not to be unreasonably withheld, to remove the Warrant
Agent or its successor in office and to appoint a new warrant agent or warrant agents to take the place of the Warrant Agent so removed;
and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(9) to assent to any compromise or arrangement with any creditor or creditors or any class or classes of creditors,
whether secured or otherwise, and with holders of any shares or other securities of the Corporation.

**7.11** **Meaning of "Extraordinary Resolution"** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) The expression "**extraordinary resolution**" when used in this Indenture means, subject
as hereinafter in this Section 7.11 and in Section 7.14 provided, a resolution proposed at a meeting of Warrantholders duly
convened for that purpose and held in accordance with the provisions of this Article 7 at which there are present in person or by
proxy at least two Warrantholders representing at least 20% of the aggregate number of all the then outstanding Warrants and passed by
the affirmative votes of Warrantholders representing not less than 66<sup>2/3</sup>% of the aggregate number of all the then outstanding
Warrants represented at the meeting and voted on the poll for such resolution.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) If, at any meeting called for the purpose of passing an extraordinary resolution, Warrantholders representing
at least 20% of the aggregate number of all the then outstanding Warrants are not present in person or by proxy within one-half hour after
the time appointed for the meeting, then the meeting, if convened by Warrantholders or on a Warrantholders' Request, shall be dissolved;
but in any other case it shall stand adjourned to such day, being not less than 10 Business Days later, and to such place and time as
may be appointed by the chairman. Not less than three Business Days prior notice shall be given of the time and place of such adjourned
meeting provided by press release of the Corporation. Such notice shall state that at the adjourned meeting the Warrantholders present
in person or represented by proxy shall form a quorum but it shall not be necessary to set forth the purposes for which the meeting was
originally called or any other particulars. At the adjourned meeting the Warrantholders present in person or represented by proxy shall
form a quorum and may transact the business for which the meeting was originally convened and a resolution proposed at such adjourned
meeting and passed by the requisite vote as provided in subsection 7.11(1) shall be an extraordinary resolution within the meaning
of this Indenture notwithstanding that Warrantholders representing at least 20% of all the then outstanding Warrants are not present in
person or represented by proxy at such adjourned meeting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Votes on an extraordinary resolution shall always be given on a poll and no demand for a poll on an extraordinary
resolution shall be necessary.

**7.12** **Powers Cumulative** 

It is hereby declared and agreed that any one or more of the powers or any combination of the powers in this Indenture stated to be exercisable by the Warrantholders by extraordinary resolution or otherwise may be exercised from time to time and the exercise of any one or more of such powers or any combination of powers from time to time shall not be deemed to exhaust the right of the Warrantholders to exercise such powers or combination of powers then or thereafter from time to time.

**7.13** **Minutes** 

Minutes of all resolutions and proceedings at every meeting of Warrantholders as aforesaid shall be made and duly entered in books to be provided for that purpose by the Corporation and any minutes as aforesaid, if signed by the chairman of the meeting at which resolutions were passed or proceedings had, or by the chairman of the next succeeding meeting of the Warrantholders, shall be prima facie evidence of the matters therein stated and, until the contrary is proved, every meeting, in respect of the proceedings of which minutes shall have been made, shall be deemed to have been duly convened and held, and all resolutions passed thereat or proceedings taken shall be deemed to have been duly passed and taken.

**7.14** **Instruments in Writing** 

All actions that may be taken and all powers that may be exercised by the Warrantholders at a meeting held as provided in this Article 7 also may be taken and exercised by Warrantholders representing a majority, or in the case of an extraordinary resolution at least 66<sup>2/3</sup>%, of the aggregate number of all the then outstanding Warrants by an instrument in writing signed in one or more counterparts by such Warrantholders in person or by attorney duly appointed in writing, and the expression "**extraordinary resolution**" when used in this Indenture shall include an instrument so signed.

**7.15** **Binding Effect of Resolutions** 

Every resolution and every extraordinary resolution passed in accordance with the provisions of this Article 7 at a meeting of Warrantholders shall be binding upon all Warrantholders, whether present at or absent from such meeting, and every instrument in writing signed by Warrantholders in accordance with Section 7.14 shall be binding upon all the Warrantholders, whether signatories thereto or not, and each and every Warrantholder and the Warrant Agent (subject to the provisions for indemnity herein contained) shall be bound to give effect accordingly to every such resolution and instrument in writing.

**7.16** **Holdings by the Corporation or Subsidiaries of the Corporation Disregarded** 

In determining whether Warrantholders are present at a meeting of Warrantholders for the purpose of determining a quorum or have concurred in any consent, waiver, extraordinary resolution, Warrantholders' Request or other action under this Indenture, Warrants owned legally or beneficially by the Corporation or its Subsidiaries or in partnership of which the Corporation is directly or indirectly a party to shall be disregarded. The Corporation shall provide, upon the written request of the Warrant Agent, a certificate as to the registration particulars of any Warrants held by the Corporation or its Subsidiaries or in partnership of which the Corporation is directly or indirectly a party.

**Article 8<br> SUPPLEMENTAL INDENTURES AND SUCCESSOR COMPANIES**

**8.1** **Provision for Supplemental Indentures for Certain Purposes** 

From time to time the Corporation and the Warrant Agent may, subject to the provisions hereof and the TSXV's approval and/or the Nasdaq's approval (if applicable), and they shall, when so required hereby, execute and deliver by their proper officers, indentures or instruments supplemental hereto, which thereafter shall form part hereof, for any one or more or all of the following purposes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) providing for the issuance of additional Warrants hereunder and any consequential amendments hereto as
may be required by the Warrant Agent, relying on the advice of counsel;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) setting forth or giving effect to adjustments in the application of Article 3;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) adding to the provisions hereof such additional covenants and enforcement provisions as, in the opinion
of counsel are necessary or advisable, provided that the same are not in the opinion of the Warrant Agent, relying on the advice of counsel,
prejudicial to the interests of the Warrantholders as a group;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) giving effect to any extraordinary resolution passed as provided in Article 7;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) making such provisions not inconsistent with this Indenture as may be necessary or desirable with respect
to matters or questions arising hereunder provided that such provisions are not, in the opinion of the Warrant Agent, relying on the advice
of counsel, prejudicial to the interests of the Warrantholders as a group;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) adding to or amending the provisions hereof in respect of the transfer of Warrants, making provision for
the exchange of Warrants and making any modification in the form of the Warrant Certificate that does not affect the substance thereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) amending any of the provisions of this Indenture or relieving the Corporation from any of the obligations,
conditions or restrictions herein contained, provided that no such amendment or relief shall be or become operative or effective if, in
the opinion of the Warrant Agent, relying on the advice of counsel, such amendment or relief impairs any of the rights of the Warrantholders
as a group or of the Warrant Agent, and provided further that the Warrant Agent may in its sole discretion decline to enter into any supplemental
indenture that in its opinion may not afford adequate protection to the Warrant Agent when the same shall become operative;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(8) providing added protection or benefit to the Corporation or the Warrantholders (as a group); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(9) for any other purpose not inconsistent with the terms of this Indenture, including the correction or rectification
of any ambiguities, defective or inconsistent provisions, errors, mistakes or clerical omissions herein, provided that, in the opinion
of the Warrant Agent, relying on the advice of counsel, the rights of the Warrant Agent and the Warrantholders as a group are in no way
prejudiced thereby.

**8.2** **Successor Companies** 

In the case of the amalgamation, consolidation, arrangement, merger or transfer of the undertaking or assets of the Corporation as an entirety or substantially as an entirety to another person (a "**successor company**"), the successor company resulting from the amalgamation, consolidation, arrangement, merger or transfer (if not the Corporation) shall be bound by the provisions hereof and all obligations for the due and punctual performance and observance of each and every covenant and obligation contained in this Indenture to be performed by the Corporation and the successor company shall by supplemental indenture satisfactory in form and substance to the Warrant Agent and executed and delivered by the successor company to the Warrant Agent, expressly assume those obligations.

**Article 9<br> CONCERNING THE WARRANT AGENT**

**9.1** **Indenture Legislation** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) If and to the extent that any provision of this Indenture limits, qualifies or conflicts with a mandatory
requirement of Applicable Legislation, such mandatory requirement shall prevail.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) The Corporation and the Warrant Agent agree that each will at all times in relation to this Indenture
and any action to be taken hereunder observe and comply with and be entitled to the benefit of Applicable Legislation.

**9.2** **Rights and Duties of Warrant Agent** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) The Warrant Agent accepts the duties and responsibilities under this Indenture, solely as custodian, bailee
and agent. No trust is intended to be, or is or will be, created hereby and the Warrant Agent shall owe no duties hereunder as a trustee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) In the exercise of the rights and duties prescribed or conferred by the terms of this Indenture, the Warrant
Agent shall act honestly and in good faith and shall exercise the degree of care, diligence and skill that a reasonably prudent warrant
agent would exercise in comparable circumstances. No provision of this Indenture shall be construed to relieve the Warrant Agent from
liability for its own gross negligence, wilful misconduct, bad faith or fraud.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) The obligation of the Warrant Agent to commence or continue any act, action or proceeding for the purpose
of enforcing any rights of the Warrant Agent or the Warrantholders hereunder shall be conditional upon the Warrantholders furnishing,
when required by notice in writing by the Warrant Agent, notice specifying the act, action or proceeding which the Warrant Agent is required
to take, sufficient funds to commence or continue such act, action or proceeding and an indemnity reasonably satisfactory to the Warrant
Agent and its counsel to protect and hold harmless the Warrant Agent, its officers, directors, employees, affiliates, agents, successors
and assigns against the costs, charges and expenses and liabilities to be incurred thereby and any loss and damage it may suffer by reason
thereof. None of the provisions contained in this Indenture shall require the Warrant Agent to expend or risk its own funds or otherwise
incur liability in the performance of any of its duties or in the exercise of any of its rights or powers unless indemnified and funded
as aforesaid.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) The Warrant Agent may, before commencing any act, action or proceeding, or at any time during the continuance
thereof require the Warrantholders at whose instance it is acting to deposit with the Warrant Agent the Warrants held by them, for which
Warrants the Warrant Agent shall issue receipts.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) Every provision of this Indenture that, by its terms, relieves the Warrant Agent of liability or entitles
it to rely upon any evidence submitted to it is subject to the provisions of Applicable Legislation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) The Warrant Agent shall not be bound to give any notice or do or take any act, action or proceeding by
virtue of the powers conferred on it hereunder unless and until it shall have been required to do so under the terms hereof or unless
and until it shall have received a Warrantholders' Request specifying the act, action or proceeding that the Warrant Agent is requested
to take; nor shall the Warrant Agent be required to take notice of any default hereunder, unless and until notified in writing of such
default, which notice shall specifically set out the default desired to be brought to the attention of the Warrant Agent and in the absence
of such notice the Warrant Agent may for all purposes of this Indenture conclusively assume that no default has occurred or been made
in the performance or observance of the representations, warranties and covenants, agreements or conditions herein contained. Any such
notice shall in no way limit any discretion herein given to the Warrant Agent to determine whether or not the Warrant Agent shall take
action with respect to any default.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) The Warrant Agent, in its personal or any other capacity, may buy, lend upon and deal in securities of
the Corporation and generally may contract and enter into financial transactions with the Corporation without being liable to account
for any profit made thereby.

**9.3** **Evidence, Experts and Advisers** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) If, in the administration of the duties of this Indenture, the Warrant Agent deems it necessary or desirable
that any matter be proved or established by the Corporation, prior to taking or suffering any action hereunder, the Warrant Agent may
accept, act, and rely upon, and shall be protected in accepting, acting, and relying upon, a certificate of the Corporation as conclusive
evidence of the truth of any fact relating to the Corporation or its assets therein stated and proof of the regularity of any proceedings
or actions associated therewith, but the Warrant Agent may in its discretion require further evidence or information before acting or
relying on any such certificate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) In addition to the reports, certificates, opinions and other evidence required by this Indenture, the
Corporation shall furnish to the Warrant Agent such additional evidence of compliance with any provision hereof and in such form as may
be prescribed by Applicable Legislation or as the Warrant Agent may reasonably require by written notice to the Corporation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) n the exercise of its rights and duties hereunder, the Warrant Agent may, if it is acting in good faith,
act and rely, and shall be protected in so acting and relying, absolutely as to the truth of the statements and the accuracy of the opinions
expressed therein, upon statutory declarations, opinions, reports, written requests, consents, or orders of the Corporation, certificates
of the Corporation or other evidence furnished to the Warrant Agent pursuant to any provision hereof or of Applicable Legislation or pursuant
to a request of the Warrant Agent. The Warrant Agent may nevertheless, in its discretion, require further proof in cases where it deems
further proof desirable. The Warrant Agent shall be under no responsibility in respect of the validity of this Indenture or the execution
and delivery hereof by or on behalf of the Corporation or in respect of the validity or the execution of any Warrant Certificate by the
Corporation and issued hereunder, nor shall it be responsible for any breach by the Corporation of any covenant or condition contained
in this Indenture or in any such Warrant Certificate; nor shall it by any act hereunder be deemed to make any representation or warranty
as to the authorization or reservation of any securities to be issued upon the right to acquire provided for in this Indenture and/or
in any Warrant or as to whether any securities will when issued be duly authorized or be validly issued and fully paid and non-assessable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) Whenever it is provided in this Indenture or under Applicable Legislation that the Corporation shall deposit
with the Warrant Agent resolutions, certificates, reports, opinions, requests, orders or other documents, it is intended that the truth,
accuracy and good faith on the effective date thereof and the facts and opinions stated in all such documents so deposited shall, in each
and every such case, be conditions precedent to the right of the Corporation to have the Warrant Agent take the action to be based thereon.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) Whenever Applicable Legislation requires that evidence referred to in this section 9.3 be in the form
of a statutory declaration, the Warrant Agent may accept the statutory declaration in lieu of a certificate of the Corporation required
by any provision hereof. Any such statutory declaration may be made by one or more of the directors or officers of the Corporation and
may be relied upon by the Warrant Agent in good faith without further inquiry.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) Proof of the execution of an instrument in writing, including a Warrantholders' Request, by any
Warrantholder may be made by a certificate of a notary public, solicitor or commissioner for oaths or other person with similar powers
that the person signing such instrument acknowledged to him the execution thereof, or by an affidavit of a witness to such execution or
in any other manner which the Warrant Agent may consider adequate and in respect of a corporate Warrantholder, shall include a certificate
of incumbency of such Warrantholder together with a certified resolution authorizing the person who signs such instrument to sign such
instrument.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) The Warrant Agent may act and rely and shall be protected in acting and relying upon any resolution, certificate,
statement, instrument, opinion, report, notice, request, consent, order, letter, or other paper document believed by it to be genuine
and to have been signed, sent or presented by or on behalf of the proper party or parties. The Warrant Agent has sole discretion and shall
be protected in acting and relying upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent,
order, letter or other paper document received in facsimile or e-mail form.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(8) The Warrant Agent may, at the Corporation's expense, employ or retain such counsel, accountants,
engineers, appraisers or other experts or advisers as it may reasonably require for the purpose of determining and discharging its rights
and duties hereunder and may pay reasonable remuneration for all services so performed by any of them, without taxation of costs of any
counsel and shall not be responsible for any misconduct or negligence on the part of any of them who has been selected with due care by
the Warrant Agent. Any reasonable remuneration paid by the Warrant Agent under this subsection 9.3(8) shall be paid by the Corporation
in accordance with Section 5.3.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(9) The Warrant Agent may act and rely and shall be protected in acting and relying in good faith on the opinion
or advice of or information obtained from any counsel, accountant, appraiser, engineer or other expert or advisor, whether retained or
employed by the Corporation or the Warrant Agent, in relation to any matter arising in fulfilling its duties and obligations hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(10) The Warrant Agent may, as a condition precedent to any action to be taken by it under this Indenture,
require such opinions, statutory declarations, reports, certificates or other evidence as it, acting reasonably, considers necessary or
advisable in the circumstances.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(11) In this Indenture, whenever confirmations or instructions are required to be given to the Warrant Agent,
in order to be valid, such confirmations and instructions shall be in writing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(12) The Warrant Agent is not required to expend or place its own funds at risk in executing its duties and
obligations.

**9.4** **Securities, Documents and Monies Held by Warrant Agent** 

Any securities, documents of title, monies or other instruments that may at any time be held by the Warrant Agent subject to the duties and obligations hereof, for the benefit of the Corporation, may be placed in the deposit vaults of the Warrant Agent or of any Schedule I Canadian chartered bank for safekeeping with any such bank (an "**Approved Bank**"). All amounts held by the Warrant Agent pursuant to this Indenture shall be held by the Warrant Agent for the Corporation and the delivery of the funds to the Warrant Agent shall not give rise to a debtor-creditor or other similar relationship. Any written direction for release of funds received shall be received by the Warrant Agent by 9 a.m. (Toronto time) on the Business Day prior to the Business Day on which such release is to be made, failing which such direction will be handled on a commercially reasonable efforts basis and may result in funds being released on the next Business Day. The amounts held by the Warrant Agent pursuant to this Indenture are at the sole risk of the Corporation and, without limiting the generality of the foregoing, but subject to Section 9.2(2), the Warrant Agent shall have no responsibility or liability for any diminution of the funds which may result from any deposit made with an Approved Bank pursuant to this Section, including any losses resulting from a default by the Approved Bank or other credit losses (whether or not resulting from such a default) including any losses on any investment liquidated prior to maturity in order to make a payment required hereunder. The parties hereto acknowledge and agree that the Warrant Agent will have acted prudently in depositing the funds at any Approved Bank, and that the Warrant Agent is not required to make any further inquiries in respect of any such bank. The Warrant Agent may hold cash balances constituting part or all such monies and need not invest same. The Warrant Agent shall not be liable to account for any profit to any parties to this Indenture or to any other person or entity.

**9.5** **Actions by Warrant Agent to Protect Interests** 

Subject to the provisions of this Indenture and Applicable Legislation, the Warrant Agent shall have the power to institute and to maintain such actions and proceedings as it may consider necessary or expedient to preserve, protect or enforce its interests and the interests of the Warrantholders.

**9.6** **Warrant Agent not Required to Give Security** 

The Warrant Agent shall not be required to give any bond or security in respect of the execution or administration of the agency, duties and obligations of this Indenture or otherwise.

**9.7** **Protection of Warrant Agent** 

By way of supplement to the provisions of any law for the time being relating to warrant agents, it is expressly declared and agreed as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) The Warrant Agent shall not be liable for or by reason of any representations, statements of fact or recitals
in this Indenture or in the Warrants (except the representation contained in Section 9.90 or be required to verify the same and all
such statements of fact or recitals are and shall be deemed to be made by the Corporation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Nothing herein contained shall impose any obligation on the Warrant Agent to see to or to require evidence
of the registration or filing (or renewal thereof) of this Indenture or any instrument ancillary or supplemental hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) The Warrant Agent shall not be bound to give notice to any person or persons of the execution hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) The Warrant Agent is in no way responsible for the use by the Corporation of the proceeds of the issue
hereunder, nor is the Warrant Agent bound to make any inquiry or investigation as to the performance by the Corporation of the Corporation's
covenants hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) The Warrant Agent shall not incur any liability or responsibility whatsoever or be in any way responsible
for the consequence of any breach on the part of the Corporation of any of the covenants or warranties herein contained or of any acts
of any directors, officers, employees, agents or servants of the Corporation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) The Warrant Agent shall retain the right not to act and shall not be liable for refusing to act if, the
Warrant Agent, due to a lack of information or instructions, or otherwise in its sole judgment, acting reasonably, determines that such
act is conflicting with or contrary to the terms of this Indenture or the law or regulation of any jurisdiction or any order or directive
of any court, governmental agency or other regulatory body.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) Without limiting any protection or indemnity of the Warrant Agent under any other provision hereof, or
otherwise at law, the Corporation hereby agrees to indemnify and hold harmless the Warrant Agent, its affiliates and their directors,
officers, agents, employees, successors and assigns (collectively, the "**Indemnified Parties**") from and against any
and all liabilities, losses, damages, penalties, claims, actions, suits, costs, taxes, charges, assessments, judgments, expenses and disbursements,
including reasonable legal or advisor fees and disbursements, of whatever kind and nature which may at any time be imposed on, incurred
by or asserted against the Indemnified Parties, or any of them, whether at law or in equity, in any way caused by or arising, directly
or indirectly, in respect of any act, deed, matter or thing whatsoever made, done acquiesced in or omitted in or about or in relation
to the execution of the Warrant Agent's duties hereunder, or any other services that Warrant Agent may provide in connection with
or in any way relating to this Indenture. The Corporation agrees that its liability hereunder shall be absolute and unconditional regardless
of the correctness of any representations of any third parties and regardless of any liability of third parties to the Indemnified Parties,
and shall accrue and become enforceable without prior demand or any other precedent action or proceeding; provided that the Corporation
shall not be required to indemnify the Indemnified Parties in the event of the gross negligence, wilful misconduct, bad faith or fraud
of the Warrant Agent. This provision shall survive the resignation or removal of the Warrant Agent, or the termination or discharge of
this Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(8) The Warrant Agent shall not be under any obligation to prosecute or defend any action or suit in respect
of this Indenture which, in the opinion of its counsel, may involve it in expense or liability, unless the Corporation shall, so often
as required, furnish the Warrant Agent with satisfactory indemnity and funding against such expense or liability. This provision shall
survive the resignation or removal of the Warrant Agent, or the termination or discharge of this Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(9) If any of the funds provided to the Warrant Agent hereunder are received by it in the form of an uncertified
cheque or bank draft, the Warrant Agent shall be entitled to delay the release of such funds and the related Warrant Shares until such
uncertified cheque has cleared the financial institution upon which the same is drawn.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(10) The forwarding of a cheque or the sending of funds by wire transfer by the Warrant Agent will satisfy
and discharge the liability of any amounts due to the extent of the sum represented thereby unless such cheque is not honoured on presentation,
provided that in the event of the non-receipt of such cheque by the payee, or the loss or destruction thereof, the Warrant Agent, upon
being furnished with reasonable evidence of such non-receipt, loss or destruction and indemnity reasonably satisfactory to it, will issue
to such payee a replacement cheque for the amount of such cheque.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(11) The Warrant 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 Warrant Agent, in its sole judgement, determines that such act might
cause it to be in noncompliance with any applicable anti-money laundering, anti-terrorist or sanctions legislation, regulation or guideline.
Further, should the Warrant Agent, in its sole judgement, determine at any time that its acting under this Warrant Indenture has resulted
in its being in non-compliance with any applicable anti-money laundering, anti-terrorist or sanctions legislation, regulation or guideline,
then it shall have the right to resign on 10 days' written notice to the Corporation provided: (i) that the Warrant Agent's
written notice shall describe the circumstances of such non-compliance to the extent permitted by such applicable anti-money laundering,
anti-terrorist or sanctions legislation, regulation or guideline; and (ii) that if such circumstances are rectified to the Warrant
Agent's satisfaction within such 10-day period, then such resignation shall not be effective.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(12) The Warrant Agent shall not be liable for any error in judgment or for any act done or step taken or omitted
by it in good faith or for any mistake, in fact or law, or for anything which it may do or refrain from doing in connection herewith except
arising out of its own gross negligence, bad faith, willful misconduct or fraud.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(13) Notwithstanding the foregoing, or any other provision of this Indenture, any liability of the Warrant
Agent shall be limited, in the aggregate, to the amount of annual retainer fees paid by the Corporation to the Warrant Agent under this
Indenture in the 12 months immediately prior to the Warrant Agent receiving the first notice of the claim. Notwithstanding any other provision
of this Indenture, and whether such losses or damages are foreseeable or unforeseeable, the Warrant Agent shall not be liable under any
circumstances whatsoever for any (a) breach by any other party of Securities Laws or other rule of any securities regulatory
authority, (b) lost profits or (c) special, indirect, incidental, consequential, exemplary, aggravated or punitive losses or
damages. This provision shall survive the resignation or removal of the Warrant Agent, or the termination or discharge of this Indenture.

**9.8** **Replacement of Warrant Agent** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) The Warrant Agent may resign its appointment and be discharged from all further duties and liabilities
hereunder by giving to the Corporation not less than 60 days prior notice in writing or such shorter prior notice as the Corporation may
accept as sufficient. The Warrantholders by extraordinary resolution shall have the power at any time to remove the existing Warrant Agent
and to appoint a new Warrant Agent. In the event of the Warrant Agent resigning or being removed as aforesaid or being dissolved, becoming
bankrupt, going into liquidation or otherwise becoming incapable of acting hereunder, the Corporation shall forthwith appoint a new Warrant
Agent unless a new Warrant Agent has already been appointed by the Warrantholders; failing such appointment by the Corporation, the retiring
Warrant Agent or any Warrantholder may apply to a judge of the Province of Ontario at the Corporation's expense, on such notice
as such judge may direct, for the appointment of a new Warrant Agent; but any new Warrant Agent so appointed by the Corporation or by
the Court shall be subject to removal as aforesaid by the Warrantholders. Any new Warrant Agent appointed under any provision of this
Section 9.8 shall be a corporation authorized to carry on the business of a transfer agent or a trust company in the Province of
Ontario and, if required by Applicable Legislation of any other province, in such other province. On any such appointment the new Warrant
Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as Warrant Agent
without any further assurance, conveyance, act or deed; but there shall be immediately executed, at the expense of the Corporation, all
such conveyances or other instruments as may, in the opinion of counsel, be necessary or advisable for the purpose of assuring the same
to the new Warrant Agent, provided that any resignation or removal of the Warrant Agent and appointment of a successor Warrant Agent shall
not become effective until the successor Warrant Agent shall have executed an appropriate instrument accepting such appointment and, at
the request of the Corporation, the predecessor Warrant Agent, upon payment of its outstanding remuneration and expenses, shall execute
and deliver to the successor Warrant Agent an appropriate instrument transferring to such successor Warrant Agent all rights and powers
of the Warrant Agent hereunder and all securities, documents of title and other instruments and all monies and properties held by the
Warrant Agent hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Upon the appointment of a successor Warrant Agent, the Corporation shall promptly notify the Warrantholders
thereof in the manner provided for in Section 10.1.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) (3) Any corporation into or with which the Warrant Agent may be merged or consolidated or amalgamated,
or to which all or substantially all of the corporate trust business is sold or otherwise transferred, or any corporation resulting therefrom
to which the Warrant Agent shall be a party, or any corporation succeeding to substantially all of the stock transfer business of the
Warrant Agent, shall be the successor to the Warrant Agent hereunder without any further act on its part or of any of the parties hereto,
provided that such corporation would be eligible for appointment as a new Warrant Agent under subsection 9.8(1).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) Any Warrants Authenticated but not delivered by a predecessor Warrant Agent may be Authenticated by the
new or successor Warrant Agent in the name of the new or successor Warrant Agent.

**9.9** **Acceptance of Duties and Obligations** 

The Warrant Agent hereby accepts the duties and obligations in this Indenture declared and provided for and agrees to perform the same upon the terms and conditions herein set forth and agrees to hold all rights, interests and benefits contained herein on behalf of those persons who become holders of Warrants from time to time issued under this Indenture.

**9.10** **Warrant Agent not to be Appointed Receiver** 

The Warrant Agent and any person related to the Warrant Agent shall not be appointed a receiver or receiver and manager or liquidator of all or any part of the assets or undertaking of the Corporation or any Subsidiary or any partnership of which the Corporation is directly or indirectly involved.

**9.11** **Authorization to Carry on Business** 

The Warrant Agent represents to the Corporation that it is registered to carry on the business of a transfer agent and warrant agent under Applicable Legislation in the Province of Ontario.

**9.12** **9.12 Securities Exchange Commission Certification** 

The Corporation represents and warrants that it is filing with the SEC as a Foreign Private Issuer (as such term is defined in the *Securities Exchange Act* of 1934) and has delivered to the Warrant Agent an Officers' Certificate certifying such "**reporting issuer**" status and other information as the Warrant Agent has requested, including, but not limited to, the Central Index Key that has been assigned for filing purposes. Should the Corporation cease to file as a Foreign Private Issuer, the Corporation covenants to deliver to the Warrant Agent an Officers' Certificate (in a form provided by the Warrant Agent) certifying a change in "reporting issuer" status and such other information as the Warrant Agent may require at such given time. The Corporation understands that the Warrant Agent is relying upon the foregoing representation, warranty and covenant in order to meet certain SEC obligations with respect to those clients who are filing with the SEC.

**Article 10<br> GENERAL**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) The Corporation or the Warrant Agent, as the case may be, may from time to time notify the other in the
manner provided in subsection 10.1(1) of a change of address which, from the effective date of such notice and until changed by like
notice, shall be the address of the Corporation or the Warrant Agent, as the case may be, for all purposes of this Indenture. A copy of
any notice of change of address given pursuant to this subsection 10.1(2) shall be available for inspection at the principal office
of the Warrant Agent in the City of Toronto, Ontario by Warrantholders during normal business hours.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) If, by reason of a strike, lockout or other work stoppage, actual or threatened, involving postal employees,
any notice to be given to the Warrant Agent or to the Corporation hereunder could reasonably be considered unlikely to reach its destination,
the notice shall be valid and effective only if it is delivered to an officer of the party to which it is addressed or if it is delivered
to that party at the appropriate address provided in subsection 10.1(1) by email or other means of prepaid, transmitted or recorded
communication and any notice delivered in accordance with the foregoing shall be deemed to have been received on the date of delivery
to the officer or if delivered by email or other means of prepaid, transmitted, recorded communication on the first Business Day following
the date of the sending of the notice by the person giving the notice.

**10.2** **Notice to the Warrantholders** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Any notice to the Warrantholders under the provisions of this Indenture shall be deemed to be validly
given if the notice is sent by prepaid mail or, if delivered by hand, to the holders at their addresses appearing in the register of holders
or if otherwise given in the manner specified herein. Any notice so delivered shall be deemed to have been received on the date of delivery
if that date is a Business Day or the Business Day following the date of delivery if such date is not a Business Day or on the third Business
Day if delivered by mail. All notices may be given to whichever one of the Warrantholders (if more than one) is named first in the appropriate
register hereinbefore mentioned, and any notice so given shall be sufficient notice to all Warrantholders and any other persons (if any)
interested in such Warrants. Accidental error or omission in giving notice or accidental failure to mail notice to any Warrantholder will
not invalidate any action or proceeding founded thereon.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) If, by reason of strike, lockout or other work stoppage, actual or threatened, involving postal employees,
any notice to be given to the Warrantholders could reasonably be considered unlikely to reach its destination, the notice may be given
in a news release disseminated through a newswire service, filed on SEDAR and posted on the Corporation's website; provided that
in the case of a notice convening a meeting of the holders of Warrants, the Warrant Agent may require such additional publications of
that notice in Toronto, Ontario, in other cities or both, as it may deem necessary for the reasonable notification of the holders of Warrants
or to comply with any applicable requirement of law or any stock exchange. Any notice so given shall be deemed to have been given on the
day on which it has been published in all of the cities in which publication was required.

**10.3** **Privacy** 

The Corporation acknowledges that the Warrant Agent may, in the course of providing services hereunder, collect or receive financial and other personal information about such parties and/or their representatives, as individuals, or about other individuals related to the subject matter hereof, and use such information for the following purposes:

to time;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) to help the Warrant Agent manage its servicing relationships with such individuals;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) to meet the Warrant Agent's legal and regulatory requirements; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) if Social Insurance Numbers are collected by the Warrant Agent, to perform tax reporting and to assist
in verification of an individual's identity for security purposes.

The Corporation acknowledges and agrees that the Warrant Agent may receive collect, use and disclose personal information provided to it or acquired by it in the course of its acting as agent hereunder for the purposes described above and, generally, in the manner and on the terms described in its privacy code, which the Warrant Agent shall make available on its website, or upon request, including revisions thereto. The Warrant Agent may transfer personal information to other companies in or outside of Canada that provide data processing and storage or other support in order to facilitate the services it provides.

Further, the Corporation agrees that it shall not provide or cause to be provided to the Warrant Agent any personal information relating to an individual who is not a party to this Indenture unless that party has assured itself that such individual understands and has consented to the aforementioned uses and disclosures.

**10.4** **Third Party Interests** 

The Corporation represents to the Warrant Agent that any account to be opened by, or interest to be held by the Warrant Agent in connection with this Indenture, for or to the credit of such party, either (i) is not intended to be used by or on behalf of any third party; or (ii) is intended to be used by or on behalf of a third party, in which case such party hereto agrees to complete and execute forthwith a declaration in the Warrant Agent prescribed form as to the particulars of such third party.

**10.5** **Discretion of Directors** 

Any matter provided herein to be determined by the directors in their sole discretion and determination so made will be conclusive.

**10.6** **Satisfaction and Discharge of Indenture** 

Upon the earlier of the Time of Expiry or the date by which there shall have been delivered to the Warrant Agent for exercise or cancellation in accordance with the provisions hereof all Warrants theretofore Authenticated hereunder, this Indenture, except to the extent that Warrant Shares and any certificates therefor have not been issued and delivered hereunder or the Corporation has not performed any of its obligations hereunder, shall cease to be of further effect in respect of the Corporation, and the Warrant Agent, on written demand of and at the cost and expense of the Corporation, and upon delivery to the Warrant Agent of a certificate of the Corporation stating that all conditions precedent to the satisfaction and discharge of this Indenture have been complied with and upon payment to the Warrant Agent of the expenses, fees and other remuneration payable to the Warrant Agent, shall execute proper instruments acknowledging satisfaction of and discharging this Indenture. Notwithstanding the foregoing, the indemnities provided to the Warrant Agent by the Corporation hereunder shall remain in full force and effect and survive the termination of this Indenture.

**10.7** **Provisions of Indenture and Warrants for the Sole Benefit of Parties and Warrantholders** 

Nothing in this Indenture or the Warrant Certificates, expressed or implied, shall give or be construed to give to any person other than the parties hereto and the holders from time to time of the Warrants any legal or equitable right, remedy or claim under this Indenture, or under any covenant or provision herein or therein contained, all such covenants and provisions being for the sole benefit of the parties hereto and the Warrantholders.

**10.8** **Ownership of Warrants** 

The Corporation and the Warrant Agent may deem and treat the Warrantholders as the absolute owner thereof for all purposes, and the Corporation and the Warrant Agent shall not be affected by any notice or knowledge to the contrary except where the Corporation or the Warrant Agent is required to take notice by statute or by order of a court of competent jurisdiction. The receipt of any such Warrantholder of the Warrant Shares which may be acquired pursuant thereto shall be a good discharge to the Corporation and the Warrant Agent for the same and neither the Corporation nor the Warrant Agent shall be bound to inquire into the title of any such holder except where the Corporation or the Warrant Agent is required to take notice by statute or by order of a court of competent jurisdiction.

**10.9** **Indenture to Prevail** 

To the extent of any discrepancy or inconsistency between the terms and conditions of this Indenture and the Warrant Certificate, the terms of this Indenture will prevail.

**10.10** **Assignment** 

Except as provided in subsection 9.8(3), neither this Indenture nor any benefits or burdens under this Indenture shall be assignable by the Corporation or the Warrant Agent without the prior written consent of the other party, such consent not to be unreasonably withheld. Subject to the foregoing, this Indenture shall enure to the benefit of and be binding upon the Corporation and the Warrant Agent and their respective successors (including any successor by reason of amalgamation) and permitted assigns.

**10.11** **Counterparts and Formal Date** 

This Indenture may be simultaneously executed in several counterparts and by electronic means, each of which when so executed shall be deemed to be an original and such counterparts together shall constitute one and the same instrument and notwithstanding their date of execution shall be deemed to bear the date set out at the top of the first page of this Indenture.

**10.12** **Force Majeure** 

No party shall be liable to the other, or held in breach of this Indenture, if prevented, hindered, or delayed in the performance or observance of any provision contained herein by reason of act of God, riots, terrorism, acts of war, epidemics, pandemics, governmental action or judicial order, earthquakes, or any other similar causes (including, but not limited to, mechanical, electronic or communication interruptions, disruptions or failures). Performance times under this Indenture shall be extended for a period of time equivalent to the time lost because of any delay that is excusable under this Section.

**10.13** **Severability** 

If, in any jurisdiction, any provision of this Indenture or its application to any party or circumstance is restricted, prohibited or unenforceable, such provision will, as to such jurisdiction, be ineffective only to the extent of such restriction, prohibition or unenforceability without invalidating the remaining provisions of this Indenture and without affecting the validity or enforceability of such provision in any other jurisdiction or without affecting its application to other parties or circumstances.

**10.14** **Rights of Rescission and Withdrawal for Holders** 

Should a Warrantholder exercise any legal, statutory, contractual or other right of withdrawal or rescission that may be available to it, and the Warrantholder's funds which were paid on exercise have already been released to the Corporation by the Warrant Agent, the Warrant Agent shall not be responsible for ensuring the exercise is cancelled and a refund is paid back to the Warrantholder. In such cases, the Warrantholder shall seek a refund directly from the Corporation and subsequently, the Corporation, upon surrender to the Corporation or the Warrant Agent of any underlying Warrant Shares or other securities that may have been issued, or such other procedure as agreed to by the parties hereto, shall instruct the Warrant Agent in writing, to cancel the exercise transaction and any such underlying Warrant Shares or other securities on the register, which may have already been issued upon the Warrant exercise. In the event that any payment is received from the Corporation by virtue of the holder being a shareholder for such Warrants that were subsequently rescinded, such payment must be returned to the Corporation by such Warrantholder. The Warrant Agent shall not be under any duty or obligation to take any steps to ensure or enforce the return of the funds pursuant to this Section, nor shall the Warrant Agent be in any other way responsible in the event that any payment is not delivered or received pursuant to this Section. Notwithstanding the foregoing, in the event that the Corporation provides the refund to the Warrant Agent for distribution to the Warrantholder, the Warrant Agent shall return such funds to the Warrantholder as soon as reasonably practicable, and in so doing, the Warrant Agent shall incur no liability with respect to the delivery or non-delivery of any such funds.

THIS CERTIFIES that, for value received, the registered holder hereof, _______________ (the "**holder**") is entitled, at any time at or before 5:00 p.m. (Toronto time) on February 13, 2028 (the "**Time of Expiry**"), to acquire, subject to adjustment in certain events, the number of common shares ("**Common Shares**") of Electra Battery Materials Corporation (the "**Corporation**") specified above, as presently constituted, by surrendering to TSX Trust Company of Canada (the "**Warrant Agent**") at its principal office in Toronto, Ontario this Warrant Certificate with the duly completed and executed Exercise Form endorsed on the back of this Warrant Certificate, and accompanied by payment of $[●] per Common Share (subject to adjustment in certain events) (the "**Exercise Price**") by certified cheque, bank draft or money order in lawful money of the United States payable to, or to the order of, the Corporation at par at the above-mentioned office of the Warrant Agent.

The holder of this Warrant Certificate may purchase less than the number of Common Shares which he is entitled to purchase on the exercise of the Warrants represented by this Warrant Certificate, in which event a new Warrant Certificate representing the Warrants not then exercised will be issued to the holder.

The Warrants evidenced hereby are exercisable on or before the Time of Expiry, after which time the Warrants evidenced hereby shall be deemed to be void and of no further force or effect.

This Warrant Certificate represents Warrants of the Corporation issued or issuable under the provisions of a warrant indenture (which indenture together with all other instruments supplemental or ancillary thereto is herein referred to as the "**Warrant Indenture**") dated as of February 13, 2023, between the Corporation and the Warrant Agent, as may be amended from time to time, which contains particulars of the rights of the holders of the Warrants and the Corporation and of the Warrant Agent in respect thereof and the terms and conditions upon which the Warrants are issued and held, all to the same effect as if the provisions of the Warrant Indenture were herein set forth, to all of which the holder of this Warrant Certificate by acceptance hereof assents. Unless otherwise defined herein, all capitalized terms shall have the meanings ascribed to them in the Warrant Indenture. A copy of the Warrant Indenture will be available for inspection at the principal office of the Corporation in the City of Toronto, Ontario. In the event of any conflict between the provisions contained in this Warrant Certificate and the provisions of the Warrant Indenture, the provisions of the Warrant Indenture shall prevail. Upon acceptance hereof, the holder hereof hereby expressly waives the right to receive any fractional Common Shares upon the exercise hereof in full or in part and further waives the right to receive any cash or other consideration in lieu thereof. The Warrants represented by this Warrant Certificate shall be deemed to have been surrendered, and payment by certified cheque, bank draft or money order shall be deemed to have been made only upon personal delivery thereof or, if sent by post or other means of transmission, upon actual receipt thereof by the Warrant Agent at its office in the city of Toronto, Ontario.

Upon due exercise of the Warrants represented by this Warrant Certificate and payment of the Exercise Price, the Corporation shall cause to be issued to the person(s) in whose name(s) the Common Shares so subscribed for (provided that if the Common Shares are to be issued to a person other than the registered holder of this Warrant Certificate, the holder's signature on the Exercise Form herein shall be guaranteed by a Schedule I Canadian chartered bank, or by a medallion signature guarantee from a member of a recognized Signature Medallion Guarantee Program and the holder shall pay to the Corporation or the Warrant Agent all applicable transfer or similar taxes and the Corporation shall not be required to issue or deliver certificates evidencing the Common Shares unless or until the holder shall have paid the Corporation or the Warrant Agent the amount of such tax (or shall have satisfied the Corporation that such tax has been paid or that no tax is due) are to be issued, the number of Common Shares to be issued to such person(s) and such person(s) shall become a holder in respect of such Common Shares with effect from the date of such exercise, and upon due surrender of this Warrant Certificate and all other documentation required, the Warrant Agent shall cause the issuance of a certificate(s) representing such Common Shares to be issued within two Business Days after the exercise of the Warrants (or portion thereof) represented hereby.

No Warrantholder will be permitted to exercise Warrants unless an exemption or exclusion from the registration requirements of the *U.S. Securities Act* and applicable state securities laws is available, and the Corporation shall promptly provide written notice of such determination to the Warrant Agent.

The holder acknowledges that the Warrants represented by this Warrant Certificate and the Common Shares issuable upon exercise hereof may be offered, sold or otherwise transferred only in compliance with all applicable securities laws.

No transfer of any Warrant will be valid unless entered on the register of transfers, upon surrender to the Warrant Agent of the Warrant Certificate evidencing such Warrant, duly endorsed by, or accompanied by a transfer form or other written instrument of transfer in form satisfactory to the Warrant Agent executed by the registered holder or his executors, administrators or other legal representatives or his or their attorney duly appointed by an instrument in writing in form and execution satisfactory to the Warrant Agent. Subject to the provisions of the Warrant Indenture and upon compliance with the reasonable requirements of the Warrant Agent, Warrant Certificates may be exchanged for Warrant Certificates representing in the aggregate an equal number of Warrants. The Corporation and the Warrant Agent may treat the registered holder of this Warrant Certificate for all purposes as the absolute owner hereof. The holding of the Warrants represented by this Warrant Certificate shall not constitute the holder hereof a holder of Common Shares nor entitle him to any right or interest in respect thereof except as herein and in the Warrant Indenture expressly provided.

The Warrant Indenture provides for adjustment in the number of Common Shares to be delivered upon exercise of the right of purchase hereby granted and to the Exercise Price in certain events therein set forth.

The Warrant Indenture contains provisions making binding upon all holders of Warrants outstanding thereunder resolutions passed at meetings of such holders held in accordance with such provisions and instruments in writing signed by the Warrantholders holding a specified percentage of the then outstanding Warrants.

The Warrants and the Warrant Indenture shall be governed by and performed, construed and enforced in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein. Time shall be of the essence hereof and of the Warrant Indenture.

The Corporation may from time to time at any time prior to the Time of Expiry purchase any of the Warrants by private agreement or otherwise.

This Warrant Certificate shall not be valid for any purpose until it has been Authenticated by or on behalf of the Warrant Agent for the time being under the Warrant Indenture.

All dollar amounts herein are expressed in the lawful money of the United States.

The signature below shall be deemed to constitute an original signature to this Warrant Certificate. This Warrant Certificate may be executed in one or more counter-parts, each of which may be delivered by facsimile, by e-mail in PDF, or other legally permissible electronic signature, and each of which will be deemed to be an original, and all of which together will be deemed to be one and the same document.
