Ladies and Gentlemen:

NexGen Energy Ltd., a corporation governed by the Business Corporations Act (British Columbia) (the “Company”), confirms its agreement (this “Agreement”) with Virtu ITG Canada Corp.

The Company has prepared and filed with the securities regulatory authorities (the “Canadian Qualifying Authorities”) in each of the provinces and territories of Canada (the “Canadian Qualifying Jurisdictions”) a preliminary short form base shelf prospectus dated December 1, 2023 (the “Canadian Preliminary Base Prospectus”) and has prepared and filed with the Canadian Qualifying Authorities in the Canadian Qualifying Jurisdictions the Canadian Base Prospectus (as defined herein) in respect of an aggregate of up to C$500,000,000 (or the equivalent thereof in U.S. dollars or any other currencies) of common shares of the Company with no par value per share (the “Common Shares”), warrants to purchase other Shelf Securities (as defined herein), subscription receipts, units comprised of one or more of any of the other Shelf Securities and debt securities or any combination thereof, of the Company (collectively, the “Shelf Securities”) in each case in accordance with Canadian Securities Laws (as defined herein). The British Columbia Securities Commission (the “Reviewing Authority”) is the principal regulator of the Company under the passport system procedures provided for under Multilateral Instrument 11-102 – Passport System and National Policy 11-202 – Process for Prospectus Reviews in Multiple Jurisdictions in respect of the Shelf Securities and the offering of the Shares. The Reviewing Authority has issued a receipt evidencing its receipt and evidencing that a receipt has been issued by the British Columbia Securities Commission and evidencing that a receipt is deemed to have been issued by the other Canadian Qualifying Authorities, for the Canadian Preliminary Base Prospectus and the Reviewing Authority has issued a receipt evidencing that a

receipt has been issued on behalf of itself and deemed to have been issued by the other Canadian Qualifying Authorities for the Canadian Base Prospectus (the “Receipt”). The term “Canadian Base Prospectus” means the final short form base shelf prospectus dated December 8, 2023 relating to the Shelf Securities, at the time the Reviewing Authority issued the Receipt with respect thereto in accordance with the applicable rules and regulations under such laws, together with applicable published national, multilateral and local policy statements, instruments, notices and blanket orders of the Canadian Qualifying Authorities in each of the Canadian Qualifying Jurisdictions and the Translation Decision (as defined herein) (the “Canadian Securities Laws”), including National Instrument 44-101 – Short Form Prospectus Distributions (“NI 44-101”) and National Instrument 44-102 – Shelf Distributions (“NI 44-102”), and includes all documents incorporated therein by reference and the documents otherwise deemed to be a part thereof or included therein pursuant to Canadian Securities Laws, including but not limited to, all Designated News Releases (as defined herein). As used herein, a “Designated News Release” means a news release disseminated by the Company disclosing information that, in the Company’s determination, constitutes a material fact (as such term is defined in Canadian Securities Laws) and identified by the Company as a “designated news release” for the purposes of the offering of Shares in writing on the face page of the version of such news release that is filed by the Company on the SEDAR+ website at ▇▇▇.▇▇▇▇▇▇▇▇▇.▇▇ (“SEDAR+”).

As used herein, “Canadian Prospectus” means the Canadian Prospectus Supplement (and any additional Canadian prospectus supplement prepared in accordance with the provisions of this Agreement and filed with the Canadian Qualifying Authorities in accordance with Canadian Securities Laws) together with the Canadian Base Prospectus. The Canadian Prospectus Supplement shall provide that any and all Designated News Releases shall be deemed to be incorporated by reference in the Canadian Base Prospectus. All Designated News Releases shall also be filed with the Securities and Exchange Commission (the “Commission”) on Form 6-K and the Canadian Prospectus Supplement shall provide that such Form 6-K shall be deemed to be incorporated by reference as an exhibit to the Registration Statement (as defined herein). The “Translation Decision” means the decision of the Autorité des marchés financiers dated November 24, 2023 obtained by the Company granting exemptive relief from the requirement that the Canadian Prospectus and the documents incorporated by reference in the Canadian Prospectus be publicly filed in both the French and English languages. For the purposes of the Canadian Prospectus, the Company is not required to publicly file French versions of the Canadian Prospectus and the documents incorporated by reference therein.

The Company has also prepared and filed with the Commission, pursuant to the Canada/U.S. Multi-Jurisdictional Disclosure System adopted by the Commission, a registration statement on Form F-10 (File No. 333-275839) covering the registration of the Shelf Securities under the Securities Act of 1933, as amended (the “Act”), and the rules and regulations of the Commission thereunder (the “Rules and Regulations”), and such amendments (including post-effective amendments) to such registration statement as may have been permitted or required to the date of this Agreement.

The Company confirms its agreement with the Agents as follows:

1. Sale and Delivery of the Shares.

(a) Agency Transactions. On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Company and the Agents agree that the Company may issue and sell through the Agents, as sales agents for the Company, the Shares (an “Agency Transaction”) as follows.

(i) The Company may, from time to time, propose to the applicable Agent the terms of an Agency Transaction by means of a telephone call or other forms of written electronic communication (confirmed promptly by electronic mail in a form substantially similar to Exhibit A hereto (an “Agency Transaction Notice”)) from any one of the individuals listed as authorized representatives of the Company on Schedule 1 hereto (each, an “Authorized Company Representative”), such proposal to include, among other parameters permitted in accordance with this Agreement: the trading day(s) for the Toronto Stock Exchange (the “TSX”) or the New York Stock Exchange (the “NYSE”) (which may not be a day on which the TSX or the NYSE, as applicable, is closed or scheduled to close prior to its regular weekday closing time) on which the Shares are to be sold (each, a “Trading Day”); the maximum number of Shares that the Company wishes to sell in the aggregate and on each Trading Day; and the minimum price at which the Company is willing to sell the Shares (the “Floor Price”). The Agency Transaction Notice shall be effective upon delivery to the applicable Agent unless and until (A) the applicable Agent declines to accept the terms contained therein and does not confirm promptly in accordance with Section 1(a)(ii), (B) the entire amount of the Shares under the Agency Transaction Notice have been sold, (C) the Company or the applicable Agent suspends or terminates the Agency Transaction Notice in accordance with the notice requirements set forth in Section 1(a)(vi) or Section 6, as applicable, (D) the Company issues a subsequent Agency Transaction Notice with parameters superseding those on the earlier Agency Transaction Notice, or (E) this Agreement has been terminated under the provisions of this Agreement. The terms of an Agency Transaction shall be proposed to, and each Agency Transaction Notice shall be addressed to, the respective individuals from the applicable Agent set forth on Schedule 1 hereto (the “Authorized Agent Representatives”).

(ii) If such proposed terms for an Agency Transaction are acceptable to the applicable Agent, it shall promptly confirm the terms by countersigning the Agency Transaction Notice for such Agency Transaction and emailing it to the Authorized Company Representatives which delivered such Agency Transaction Notice. In the event of a conflict

between the terms of this Agreement and the terms of an Agency Transaction Notice, the terms of the Agency Transaction Notice will prevail.

(iii) Subject to the terms and conditions hereof, the applicable Agent shall, severally and not jointly, use its commercially reasonable efforts to sell all of the Shares designated in, and subject to the terms of, such Agency Transaction Notice. The applicable Agent shall not sell any Share at a price lower than the Floor Price. The Company acknowledges and agrees with the Agents that (x) there can be no assurance that an Agent will be successful in selling all or any of such Shares or as to the price at which any Shares are sold, if at all, (y) no Agent shall incur liability or obligation to the Company or any other person or entity if they do not sell any Shares for any reason, and (z) no Agent shall be under any obligation to purchase any Shares on a principal basis pursuant to this Agreement.

(iv) Each of the Agents hereby covenants and agrees that during the time an Agent receives an Agency Transaction Notice pursuant to Section 1(a)(i) hereof that has not been suspended or terminated in accordance with the terms hereof, such Agent will monitor closely the market’s reaction to trades made on marketplaces (as such term is defined in National Instrument 21-101 – Marketplace Operation) pursuant to this Agreement in order to evaluate the likely market impact of future trades, and that, if such Agent has concerns as to whether a particular sale contemplated by an Agency Transaction Notice may have a significant effect on the market price of the Common Shares, the applicable Agent will, upon receipt of the applicable Agency Transaction Notice, recommend to the Company against effecting the trade at that time. Notwithstanding the foregoing, the Company acknowledges and agrees that the Agents cannot provide complete assurances that any sale will not have a significant effect on the market price of the Shares.

(v) The Agents, severally and not jointly, covenant that the Agents will not (nor will any person or company acting jointly or in concert therewith), in connection with the distribution of Shares in an “at-the-market distribution” (as defined in NI 44-102), enter into any transaction that is intended to stabilize or maintain the market price of the Common Shares, including selling an aggregate number or principal amount of Shares that would result in an Agent creating an over-allocation position in the Shares.

(vi) The Company, or the applicable Agent or Agents, may, upon notice to the other party or parties, in writing, by telephone (confirmed immediately by e-mail) or by e-mail notice (or other method mutually agreed to in writing by the parties), suspend or terminate any sale of Shares for any reason at any time for which it has delivered or received, as applicable, an Agency Transaction Notice; provided, however, that such suspension or termination shall not affect or impair any party’s obligations with respect to any Shares sold hereunder prior to the receipt of such notice. The parties agree that no such notice shall be effective against any other party unless it is made by and to, with respect to the Company, each of the Authorized Company Representatives or, with respect to the applicable Agent, each of the Authorized Agent Representatives, and in each case as Schedule 1 may be amended from time to time by written notice to each of the parties hereto.

(vii) If the terms of any Agency Transaction as set forth in an Agency Transaction Notice contemplate that the Shares shall be sold on more than one Trading Day, then

the Company and the applicable Agent shall mutually agree to such additional terms and conditions as they deem necessary in respect of such multiple Trading Days, and such additional terms and conditions shall be binding to the same extent as any other terms contained in the relevant Agency Transaction Notice.

(viii) The applicable Agent, as sales agent in an Agency Transaction, shall not make any sales of the Shares on behalf of the Company, pursuant to this Agreement, other than by means of ordinary brokers’ transactions (x) that qualify for delivery of the Prospectus in accordance with Rule 153 of the Rules and Regulations and meet the definition of an “at the market offering” under Rule 415(a)(4) of the Rules and Regulations, (y) that constitute an “at-the-market-distribution” under NI 44-102, including, without limitation, sales made directly on the TSX and the NYSE, or any Canadian or United States marketplace, or (z) such other sales of the Shares on behalf of the Company in its capacity as agent of the Company as shall be agreed by the Company and the applicable Agent in writing.

(ix) The compensation to each Agent for sales of the Shares in an Agency Transaction with respect to which such Agent acts as sales agent hereunder shall be as set forth in the Agency Transaction Notice for such Agency Transaction but shall not exceed 1% of the gross offering proceeds of the Shares sold in such Agency Transaction. The applicable Agent shall provide written confirmation to the Company (which may be provided by email to at least two of the Authorized Company Representatives) following the close of trading on each Trading Day on which Shares are sold in an Agency Transaction under this Agreement, setting forth (i) the number and the average price of Shares sold on such Trading Day (showing the number and the average price of Shares sold on the TSX, on the NYSE or on any other “marketplace”), (ii) the gross offering proceeds received from such sales, (iii) the commission payable by the Company to such Agent with respect to such sales (which commission shall be paid in the same currency as the sale of the Shares to which such commission pertains) and (iv) the net offering proceeds (being the gross offering proceeds for such sales less the commission payable for such sales) (the “Net Offering Proceeds”).

(x) Settlement for sales of the Shares in an Agency Transaction pursuant to this Agreement shall occur on the second Trading Day (or such earlier day as is industry practice for regular-way trading) following the date on which such sales are made (each such day, a “Settlement Date”). On each Settlement Date, the Shares sold through the applicable Agent in Agency Transactions for settlement on such date shall be issued and delivered by the Company to the applicable Agent against payment by the applicable Agent to the Company of the Net Offering Proceeds from the sale of such Shares. Settlement for all such Shares shall be effected by free delivery of the Shares by the Company or its transfer agent to the applicable Agent’s or its designee’s account (provided that the applicable Agent shall have given the Company written notice of such designee prior to the relevant Settlement Date) at The Canadian Depository for Securities (“CDS”), The Depository Trust Company or by such other means of delivery as may be mutually agreed upon by the parties hereto, which in all cases shall be freely tradable, transferable, registered shares in good deliverable form, which may include book-entry, in return for payment in same-day funds delivered to the account designated by the Company. If the Company, or its transfer agent (if applicable), shall default on its obligation to deliver the Shares on any Settlement Date, the Company shall (i) hold the applicable Agent harmless against any loss, claim, damage, or expense (including, without limitation, reasonable legal fees and expenses), as incurred, arising

out of or in connection with such default by the Company and (ii) pay the applicable Agent any commission, discount or other compensation to which it would otherwise be entitled absent such default, provided, however, that without limiting Section 5 herein, with respect to (ii) above, the Company shall not be obligated to pay the applicable Agent any commission, discount or other compensation on any Shares that it is not possible to settle due to: (A) a suspension or material limitation in trading in securities generally on the TSX or the NYSE; (B) a material disruption in securities settlement or clearance services in the United States or Canada; or (C) failure by the applicable Agent to comply with its obligations under the terms of this Agreement.

(b) Maximum Number of Shares. Under no circumstances shall the Company propose to any one of the Agents, or any one of the Agents effect, a sale of Shares in an Agency Transaction pursuant to this Agreement if such sale would (i) cause the aggregate gross sales proceeds of the Shares sold pursuant to this Agreement to exceed the Maximum Amount, (ii) cause the number of Shares sold to exceed the number of shares of Common Shares available for offer and sale under the then effective Canadian Prospectus or Registration Statement or (iii) cause the number of Shares sold pursuant to this Agreement to exceed the number of Shares authorized from time to time to be issued and sold pursuant to this Agreement by the Company’s board of directors, or a duly authorized committee thereof, and notified to the applicable Agent in writing.

(c) Regulation M. If any party hereto has reason to believe that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the Company or the Shares, it shall promptly notify the other parties and sales of Shares under this Agreement shall be suspended until that or other exemptive provisions have been satisfied in the judgment of each party hereto.

(d) Black-out Periods. Notwithstanding any other provision of this Agreement, no sales of Shares shall take place, the Company shall not request the sales of any Shares that would be sold and the Agents shall not be obligated to sell or offer to sell any Shares, during any period in which the Company’s ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ or similar policy, as it exists on the date of this Agreement, would prohibit the purchase or sale of Common Shares by persons subject to such policy, or during any other period in which the Company is, or could be deemed to be, in possession of material non-public information with respect to the Company.

(e) Continuing Accuracy of Representations and Warranties. Any obligation of the Agents to use their commercially reasonable efforts to sell the Shares on behalf of the Company as sales agents shall be subject to the continuing accuracy of the representations and warranties of the Company herein, to the performance by the Company of its obligations hereunder and to the continuing satisfaction of the conditions specified in Section 3 of this Agreement.

2. Representations and Warranties of the Company. The Company represents and warrants to, and covenants with, the Agents as follows:

(a) Effectiveness of Registration. The Company is qualified in accordance with the provisions of NI 44-101 and NI 44-102 to file a short form base shelf prospectus in each of the Canadian Qualifying Jurisdictions and the entering into of this Agreement will not cause the Receipt to no longer be effective. At the time of filing the Registration Statement, the Company met, and as of the date hereof the Company meets, the general eligibility requirements for use of

Form F-10 under the Act. Any amendment or supplement to the Registration Statement or the Prospectuses required by this Agreement will be so prepared and filed by the Company and, as applicable, the Company will use commercially reasonable efforts to cause it to become effective as soon as reasonably practicable. The Commission’s website indicates that no stop order suspending the effectiveness of the Registration Statement is in effect. No proceedings for such purpose have been instituted or are pending or, to the best knowledge of the Company, are contemplated or threatened by any Canadian Qualifying Authority or similar regulatory authority or the TSX, the NYSE, or the Commission. No order preventing or suspending the use of the Base Prospectuses, the Prospectus Supplements, the Prospectuses or any Permitted Free Writing Prospectus (as defined herein) has been issued by the Commission or any Canadian Qualifying Authority. The Canadian Prospectus, at the time of filing thereof with the Canadian Qualifying Authorities, complied in all material respects and, as amended or supplemented, if applicable, will comply in all material respects with Canadian Securities Laws. The Canadian Prospectus, as amended or supplemented, as of its date, did not and, as of each Time of Sale (as defined herein) and Settlement Date, if any, will not contain a misrepresentation, as defined under Canadian Securities Laws. The Canadian Prospectus, as amended or supplemented, as of its date, did and, as of each Time of Sale and Settlement Date, if any, will contain full, true and plain disclosure of all material facts relating to the Shares and to the Company. The representations and warranties set forth in the two immediately preceding sentences do not apply to statements in or omissions from the Canadian Prospectus, or any amendments or supplements thereto, made in reliance upon and in conformity with information relating to the Agents furnished to the Company in writing by or on behalf of the Agents expressly for use therein. The U.S. Prospectus, at the time first filed in accordance with General Instruction II.L. of Form F-10, conformed in all material respects and, as amended or supplemented, if applicable, will conform in all material respects to the Canadian Prospectus, except for such deletions therefrom and additions thereto as are permitted or required by Form F-10 and the Rules and Regulations. The Company has delivered to the Agents one complete copy of each of the Canadian Base Prospectus and the Registration Statement and a copy of each consent of experts filed as a part thereof, and conformed copies of the Canadian Base Prospectus, the Registration Statement (without exhibits) and the Prospectuses, as amended or supplemented, in such quantities and at such places as the Agents have reasonably requested. At the time of filing the Registration Statement and at the earliest time after the filing of the Registration Statement that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) under the Act) of the Shares, the Company was not and, as of the date of this Agreement, is not, an Ineligible Issuer (as defined in Rule 405 under the Act), without taking account of any determination by the Commission pursuant to Rule 405 under the Act that it is not necessary that the Company be considered an Ineligible Issuer. “Time of Sale” means the time of the applicable Agent’s initial entry into contracts with investors for the sale of such Shares.

(b) Accuracy. Each part of the Registration Statement, when such part became or becomes effective, at any deemed effective date pursuant to Form F-10 and the Rules and Regulations on the date of filing thereof with the Commission and at each Time of Sale and Settlement Date, and the U.S. Prospectus, on its date, or the date of filing thereof with the Commission and at each Time of Sale and Settlement Date, as amended or supplemented, conformed or will conform in all material respects with the requirements of the Rules and Regulations; each part of the Registration Statement, when such part became or becomes effective, did not and will not contain an untrue statement of a material fact or omit to state a material fact

required to be stated therein or necessary to make the statements therein not misleading; and the U.S. Prospectus, on its date and the date of filing thereof with the Commission on ▇▇▇▇▇, and the U.S. Prospectus and the applicable Permitted Free Writing Prospectus(es), if any, issued at or prior to such Time of Sale, taken together (collectively, and with respect to any Shares, together with the public offering price of such Shares, the “Disclosure Package”), in each case at each Time of Sale and Settlement Date, did not and will not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; except that the foregoing shall not apply to statements or omissions in any such document made in reliance upon and in conformity with information relating to the Agents furnished in writing to the Company by or on behalf of the Agents specifically for inclusion in the Registration Statement, the U.S. Prospectus or any Permitted Free Writing Prospectus, or any amendment or supplement thereto.

(c) Permitted Free Writing Prospectus. Each Permitted Free Writing Prospectus, if any, as of its issue date and at all subsequent times through the completion of the offering of the Shares or until any earlier date that the Company notified or notifies the Agents as described in Section 3(aa)(iii), did not, does not and will not include any material information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, the U.S. Base Prospectus or the U.S. Prospectus, in each case including any document incorporated by reference therein and any prospectus supplement deemed to be a part thereof that has not been superseded or modified, or includes an untrue statement of a material fact or omitted or would omit to state a material fact required to be stated therein or necessary in order to make the statements therein the light of the circumstances under which they were made, not misleading. The foregoing sentence does not apply to statements in or omissions from any Permitted Free Writing Prospectus in reliance upon, and in conformity with, written information furnished to the Company by or on behalf of the Agents specifically for inclusion therein.

(d) Due Incorporation. The Company has been duly incorporated and is validly existing under the laws of British Columbia and has all requisite corporate power and authority to own, lease and operate its properties and assets, to conduct its business as now carried on by it as is or will be described in the Registration Statement, the Prospectuses and the Disclosure Package, (collectively, the “Offering Documents”) and to enter into, deliver and perform its obligations under this Agreement. The Company is duly qualified or authorized to transact business and is in good standing (in respect of the filing of annual returns where required or other information filings under applicable corporations information legislation) in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business.

(e) Material Subsidiaries. The Company’s subsidiaries (each a “Subsidiary” and collectively, the “Subsidiaries”) listed on Schedule 2 hereto (each, a “Material Subsidiary” and, collectively, the “Material Subsidiaries”) are the only Subsidiaries that are “significant subsidiaries” of the Company within the meaning of Rule 1-02(w) of Regulation S-X under the Act or are otherwise material to the Company; no Subsidiary is currently prohibited, directly or indirectly, from paying any dividends to the Company, from making any other distribution on such Subsidiary’s capital stock, from repaying to the Company any loans or advances to such Subsidiary from the Company or from transferring any of such Subsidiary’s property or assets to the Company or any other Subsidiary of the Company; all of the issued share capital of or other ownership

interests in each Subsidiary have been duly and validly authorized and issued and are fully paid and non-assessable and (except as otherwise set forth in the Offering Documents) are owned directly or indirectly by the Company free and clear of any lien, charge, mortgage, pledge, security interest, claim, or other encumbrance of any kind whatsoever (each, a “Lien”); each Subsidiary has been duly organized and validly exists as a corporation, partnership or limited liability company in good standing under the laws of the jurisdiction of its organization, with full corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Offering Documents; each Subsidiary is duly qualified to do business and is in good standing in each jurisdiction in which the character or location of its properties (owned, leased or licensed) or the nature or conduct of its business makes such qualification necessary, except for those failures to be so qualified or in good standing which (individually or in the aggregate) could not reasonably be expected to have a material adverse effect on (i) the business, general affairs, management, condition (financial or otherwise), results of operations, shareholders’ equity, properties or prospects of the Company and its Subsidiaries, taken as a whole, or (ii) the ability of the Company to consummate the transactions contemplated by this Agreement (together with paragraph (i) a “Material Adverse Effect”).

(f) Capitalization. As of the date of this Agreement, the Company has an authorized and outstanding capitalization as set forth in the Offering Documents, and, as of the time of purchase and any additional time of purchase, as the case may be, the Company shall have an authorized and outstanding capitalization as set forth in the Offering Documents (subject, in each case, to (i) the issuance of Common Shares upon exercise or conversion, as applicable, of stock options, warrants or other convertible securities (including the settlement of any interest thereon in accordance with the terms thereof) disclosed as outstanding in the Offering Documents, (ii) the grant of options under existing stock option plans described in the Offering Documents, (iii) the issuance of Common Shares on the exercise or deemed exercise of such options) and (iv) such other issuances of Common Shares undertaken by the Company in the ordinary course of business from time to time; all of the issued and outstanding share capital of the Company, being the Common Shares, have been duly authorized and validly issued and are fully paid and non-assessable, have been issued in compliance with all applicable Canadian, U.S. and other securities laws and were not issued in violation of any pre-emptive right, resale right, right of first refusal or similar right; the Common Shares are duly listed, and admitted and authorized for trading, on the TSX, the NYSE and the Australian Securities Exchange (the “ASX”).

(b) Notice of Stop Orders. The Company will advise the Agents, promptly after it receives notice thereof, of the issuance by the Commission or the Canadian Qualifying Authorities of any stop order or of any order preventing or suspending the use of the Prospectuses or other prospectus in respect of the Shares, of any notice of objection of the Commission to the use of the form of the Registration Statement or any post-effective amendment thereto, of the suspension of the qualification of the Shares for offering or sale in the United States or the Canadian Qualifying Jurisdictions, of the initiation or threatening of any proceeding for any such

purpose, or of any request by the Commission or the Canadian Qualifying Authorities for the amending or supplementing of the Registration Statement or the Prospectuses or for additional information relating to the Shares. If there is an Agency Transaction Notice that has been issued by the Company that has not been suspended or terminated in accordance with the notice requirements set forth in Section 1(a)(vi) or Section 6, as applicable, the Company will use its commercially reasonable efforts to prevent the issuance of any stop order or any order preventing or suspending the use of the Prospectuses or other prospectus in respect of the Shares, a notice of objection of the Commission to the form of the Registration Statement or any post-effective amendment thereto, the suspension of any qualification for offering or sale in the United States or the Canadian Qualifying Jurisdictions, and, in the event of the issuance of any such stop order or any such order preventing or suspending the use of any prospectus relating to the Shares or suspending any such qualification, the Company will use its commercially reasonable efforts to obtain the lifting or withdrawal of such order as soon as possible. If there is no such outstanding Agency Transaction Notice, then, if, in the Company’s determination and at the Company’s sole discretion, it is necessary to prevent the issuance of any stop order or have a stop order lifted, the Company will use its commercially reasonable efforts to prevent the issuance of any stop order or any order preventing or suspending the use of the Prospectuses or other prospectus in respect of the Shares, a notice of objection of the Commission to the form of the Registration Statement or any post-effective amendment thereto, the suspension of any qualification for offering or sale in the United States or the Canadian Qualifying Jurisdictions, and, in the event of the issuance of any such stop order or any such order preventing or suspending the use of any prospectus relating to the Shares or suspending any such qualification, the Company will use its commercially reasonable efforts to obtain the lifting or withdrawal of such order as soon as possible.

(c) Delivery of Prospectus; Subsequent Changes. Within the time during which a prospectus relating to the Shares is required to be delivered by the Agents under the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 153, Rule 172 or Rule 173(a) under the Act) or the Canadian Securities Laws, the Company will comply in all material respects with all requirements imposed upon it by the Act and the Rules and Regulations, as appropriate and as from time to time in force, and will file or furnish on or before their respective due dates all reports required to be filed or furnished by it with the Commission pursuant to Sections 13(a), 13(c), or 15(d) of the Exchange Act, if applicable, or any other provision of or under the Exchange Act or with the Canadian Qualifying Authorities pursuant to the Canadian Securities Laws, as appropriate. If during such period any event occurs as a result of which the Prospectuses as then amended or supplemented would include an untrue statement of material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances then existing, not misleading, or if during such period it is necessary to amend or supplement the Registration Statement or the Prospectuses to comply with the Act or the Canadian Securities Laws, the Company will promptly notify the Agents to suspend the offering of Shares during such period and, if, in the Company’s determination and at the Company’s sole discretion, it is necessary to file an amendment or supplement to the Registration Statement or the Prospectuses to comply with the Act or the Canadian Securities Laws, the Company will promptly prepare and file with the Canadian Qualifying Authorities and the Commission such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectuses comply with such requirements, and the Company will furnish to the Agents such number of copies of such amendment or supplement as the Agents may reasonably request.

The Company shall cooperate with the Agents and their counsel in connection with the registration or qualification (or the obtaining of exemptions therefrom) of the Shares for the offering and sale under the securities or Blue Sky laws of such jurisdictions in the United States, and to continue such registration or qualification in effect so long as necessary under such laws for the distribution of the Shares; provided, however, that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action which would subject it to general service of process in any jurisdiction where it is not now so subject (except service of process with respect to the offering and sale of the Shares). The Company will advise the Agents promptly of the suspension of the qualification or registration of (or any exemption relating to) the Shares for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, the Company shall use its reasonable efforts to obtain the withdrawal thereof as soon as reasonably practicable.

The Company shall notify the Agents immediately by an email addressed to each of the respective individuals from each of the Agents set forth on Schedule 1 attached hereto if the Shares cease to qualify as an “actively-traded security” exempted from the requirements of Rule 101 of Regulation M under the Exchange Act by subsection (c)(1) of such rule and the sales shall be suspended until that or other exemptive provisions have been satisfied in the judgement of each party.

(aa) Permitted Free Writing Prospectuses.

(i) The Company represents and agrees that it has not made and, unless it obtains the prior written consents of the Agents, shall not make, any offer relating to the Shares that would constitute a “free writing prospectus” as defined in Rule 405 of the Rules and Regulations, which is required to be retained by the Company under Rule 433 of the Rules and Regulations; provided that the prior written consents of the Agents hereto shall be deemed to have been given in respect of each of the free writing prospectuses set forth in Schedule 3 hereto. Any such free writing prospectus consented to by the Agents is herein referred to as a “Permitted Free Writing Prospectus”. The Company represents and agrees that (i) it has treated and shall treat, as the case may be, each Permitted Free Writing Prospectus as a “free writing prospectus” as defined in Rule 405 of the Rules and Regulations and (ii) it has complied and shall comply, as the case may be, with the requirements of Rules 164 and 433 of the Act applicable to any Permitted Free Writing Prospectus, including, without limitation, in respect of timely filing with the Commission, legending and record keeping. The Company agrees not to take any action that would result in the Agents or the Company being required to file pursuant to Rule 433(d) under the Act a free writing prospectus prepared by or on behalf of the Agents that the Agents otherwise would not have been required to file thereunder.

(ii) The Company agrees that no Permitted Free Writing Prospectus, if any, will include any information that conflicts with the information contained in the Registration Statement, including any document incorporated by reference therein that has not been superseded or modified, or the Prospectuses. In addition, no Permitted Free Writing Prospectus, if any, together with the Prospectuses, will include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided however, the foregoing shall not apply to any statements or omissions in any Permitted Free Writing Prospectus made in reliance on information furnished in writing to the Company by the Agents expressly stating that such information is intended for use therein.

(iii) The Company agrees that if at any time following issuance of a Permitted Free Writing Prospectus any event occurred or occurs as a result of which such Permitted Free Writing Prospectus would conflict with the information in the Registration Statement, including any document incorporated by reference therein that has not been superseded or modified, or the Prospectuses or would include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the Company will give prompt notice thereof to the Agents and, if requested by the Agents, will prepare and furnish without charge to the Agents a Permitted Free Writing Prospectus or other document which will correct such conflict, statement or omission; provided, however, the foregoing shall not apply to any statements or omissions in any Permitted

Free Writing Prospectus made in reliance on information furnished in writing to the Company by the Agents expressly stating that such information is intended for use therein.

(bb) Distribution of Offering Materials. The Company has not distributed and will not distribute, during the term of this Agreement, any “marketing materials” (as defined in National Instrument 41-101 – General Prospectus Requirements) in connection with the offering and sale of the Shares other than the Registration Statement, the Prospectuses or any Permitted Free Writing Prospectus reviewed and consented to by the Agents and included in an Agency Transaction Notice, provided that the Agents, severally and not jointly, covenant with the Company not to take any action that would result in the Company being required to file with the Canadian Qualifying Authorities any “marketing materials” that otherwise would not be required to be filed by the Company, but for the action of the Agents.

(cc) Purchases under Normal Course Issuer Bid. Without having first agreed with the applicable Agent, acting reasonably, as to the appropriate adjustments, if any, to be made to the parameters set forth in such Agency Transaction Notice, the Company will not purchase Common Shares, and not permit any of its affiliates or any person acting on its behalf to purchase Common Shares, under a normal course issuer bid throughout (i) any period during which an Agency Transaction Notice is pending, (ii) the period beginning on the second business day immediately prior to the date on which any Agency Transaction Notice is delivered to an Agent hereunder and ending on the second business day immediately following the final Settlement Date with respect to the Shares sold pursuant to such Agency Transaction Notice, and (iii) during the “restricted period” (as set forth in Rule 100 of Regulation M), which will be either one “business day” or five “business days” (depending on whether or not the Company’s average daily trading volume value is US$100,000 or more and it has a public float of US$25 million or more at the time of such Agency Transaction Notice) immediately prior to the date on which any Agency Transaction Notice is delivered to the Agent hereunder and ending after the final Settlement Date with respect to the Shares sold and the distribution of any Shares sold pursuant to such Agency Transaction Notice to purchasers and the completion of any stabilization arrangements and trading restrictions in connection with such distribution contemplated by such Agency Transaction Notice.

4. Conditions to the Agents’ Obligations. The obligations of the Agents hereunder are subject to (i) the accuracy of the representations and warranties of the Company on the date hereof, on each Representation Date and as of each Time of Sale and each Settlement Date, (ii) the performance of the Company of its obligations hereunder and (iii) the following additional conditions (or waiver thereof by the Agents in their sole discretion):

None of the following events shall have occurred and be continuing: (i) receipt by the Company of any request for additional information from the Commission, the Canadian Qualifying Authorities or any other federal or state or foreign or other governmental, administrative or self-regulatory authority during the period of effectiveness of the Registration Statement and the Prospectuses, the response to which would require any amendments or supplements to the Registration Statement or the Prospectuses; (ii) the issuance by the Commission, the Canadian Qualifying Authorities or any other federal or state or foreign or other governmental authority of any stop order suspending the effectiveness of the Registration Statement or the Prospectuses or the initiation of any proceedings for that purpose; (iii) receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Shares for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; (iv) the occurrence of any event that makes any statement made in the Registration Statement or the Prospectuses or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires the making of any changes in the Registration Statement, the Prospectuses or any document incorporated or deemed to be incorporated therein by reference so that, in the case of the Registration Statement, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and in the case of each of the Prospectuses, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and (v) the Company’s reasonable determination that a post-effective amendment to the Registration Statement or Prospectuses would be appropriate.

(d) Officers’ Certificates. The Agents shall have received, upon execution of this Agreement and on each Representation Date, one or more accurate certificates, dated such date and signed by an executive officer of the Company, in form and substance satisfactory to the Agents, to the effect set forth in clauses (b) and (c) above and to the effect that:

(ii) as of such date and as of each Time of Sale subsequent to the immediately preceding Representation Date, if any, neither the Registration Statement, the Prospectuses nor any Permitted Free Writing Prospectus contained any untrue statement of a material fact or omitted to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(iii) each of the representations and warranties of the Company contained in this Agreement are, as of such date and each Time of Sale subsequent to the immediately preceding Representation Date, if any, true and correct; and

(g) Title Opinions. The Agents shall have received the opinions to be delivered pursuant to Section 3(t) on or before the date on which such delivery of such opinions is required pursuant to Section 3(t).

(h) Due Diligence. The Company shall have complied with all of its due diligence obligations required pursuant to Section 3(l).

(i) Compliance with Blue Sky Laws. The Shares shall be qualified for sale in such states and jurisdictions in the United States, as the Agents may reasonably request, and each such qualification shall be in effect and not subject to any stop order or other proceeding on the relevant Representation Date.

(j) Stock Exchange Listing. The Shares shall have been duly authorized for listing on the TSX, the NYSE and the ASX, subject only to notice of issuance at or prior to the applicable Settlement Date. The Company will maintain the listing of the Shares on the TSX, the NYSE and the ASX, and the Company will keep available, at all times, free of preemptive rights, Shares for the purpose of enabling the Company to satisfy its obligations under this Agreement.

(k) Securities Act Filings Made.

(l) FINRA. If a filing with FINRA is required, FINRA shall not have objected to the fairness or reasonableness of the terms or arrangements under this Agreement.

(m) Regulation M. The Common Shares shall qualify as an “actively-traded security” excepted from the requirements of Rule 101 of Regulation M under the Exchange Act by subsection (c)(1) of such rule.

(n) Additional Certificates. The Company shall have furnished to the Agents such certificate or certificates, in addition to those specifically mentioned herein, as the Agents may have reasonably requested as to the accuracy and completeness at each Representation Date of any statement in the Registration Statement or the Prospectuses or any documents filed under the Exchange Act and Canadian Securities Laws and deemed to be incorporated by reference into the Prospectuses, as to the accuracy at such Representation Date of the representations and warranties of the Company herein, as to the performance by the Company of its obligations hereunder, or as to the fulfillment of the conditions concurrent and precedent to the obligations hereunder of the Agents.

Promptly after execution of this Agreement, and in any event before any sales of Shares are made hereunder, the Company shall file this Agreement with the Canadian Qualifying Authorities in accordance with applicable Canadian Securities Laws.

5. Indemnification.

(a) Indemnification of the Agents. The Company shall indemnify and hold harmless each of the Agents, the directors, officers, employees, counsel and agents of each of the Agents and each person, if any, who controls any Agent within the meaning of Section 15 of the Act or Section 20 of the Exchange Act from and against any and all losses, claims, liabilities, expenses and damages (including, without limitation, any and all investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding between any of the indemnified parties and any indemnifying parties or between any indemnified party and any third party, or otherwise, or any claim asserted), to which they, or any of them, may become subject under the Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, liabilities, expenses or damages arise out of or are based on (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including all documents incorporated therein by reference, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements

therein not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Permitted Free Writing Prospectus or the Prospectuses (or any amendment or supplement thereto) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iii) any untrue statement or alleged untrue statement of a material fact contained in any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Shares, including any roadshow or investor presentations made to investors by the Company (whether in person or electronically) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Company shall not be liable to the extent that such loss, claim, liability, expense or damage arises from the sale of the Shares in the public offering to any person by the Agents and is based on an untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to the Agents furnished in writing to the Company by the Agents expressly for inclusion in the Registration Statement, the Prospectuses or any Permitted Free Writing Prospectus; and, provided further, that none of the foregoing indemnities shall apply if and to the extent that a court of competent jurisdiction in a final judgment from which no appeal can be made or a regulatory authority in a final ruling from which no appeal can be made shall determine that the losses, liability, claims, damages or expenses resulted solely from the gross negligence, fraud or willful misconduct of an indemnified party claiming indemnity, in which case this indemnity agreement shall cease to apply to such indemnified party in respect of such claim. For greater certainty, the Company and the Agents agree that they do not intend that any failure by the Agents to conduct such reasonable investigation as necessary to provide the Agents with reasonable grounds for believing the Prospectuses contained no misrepresentation shall constitute “gross negligence”, “fraud” or “wilful misconduct” for the purposes of this Section 5 or otherwise disentitle the Agents from indemnification hereunder. This indemnity agreement will be in addition to any liability that the Company might otherwise have.

(b) Indemnification of the Company. Each Agent shall, severally and not jointly, indemnify and hold harmless the Company, its agents, each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, each director of the Company and each officer of the Company who signs the Registration Statement to the same extent as the foregoing indemnity from the Company to the Agents, but only insofar as losses, claims, liabilities, expenses or damages arise out of or are based on any untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to an Agent furnished in writing to the Company by an Agent expressly for inclusion in the Registration Statement, any Permitted Free Writing Prospectus or the Prospectuses. This indemnity will be in addition to any liability that the Agents might otherwise have. The Company acknowledges that the names of the Agents set forth on the front and back covers, on the certificate of the Agents and under the heading “Relationship with Certain of the Agents (Conflicts of Interest)” in the Prospectus Supplements constitute the only information furnished in writing by or on behalf of the Agents for inclusion in the Registration Statement, any Permitted Free Writing Prospectus or the Prospectuses.

(c) Indemnification Procedures. Any party that proposes to assert the right to be indemnified under this Section 5 shall, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying

party or parties under this Section 5, notify each such indemnifying party of the commencement of such action, enclosing a copy of all papers served, but the omission so to notify such indemnifying party shall not relieve the indemnifying party from any liability that it may have to any indemnified party under the foregoing provisions of this Section 5 unless, and only to the extent that, such omission results in the forfeiture of substantive rights or defenses by the indemnifying party or results in any increase in the liability under this indemnity that the indemnifying party would not otherwise have incurred had the indemnified party given the required notice. If any such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with counsel satisfactory to the indemnified party, and after notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any legal or other expenses except as provided below and except for the reasonable costs of investigation subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own counsel in any such action, but the fees, expenses and other charges of such counsel will be at the expense of such indemnified party unless (i) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (ii) the indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (iii) a conflict or potential conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party shall not have the right to direct the defense of such action on behalf of the indemnified party) or (iv) the indemnifying party has not in fact employed counsel to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees, disbursements and other charges of counsel shall be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time for all such indemnified party or parties. All such fees, disbursements and other charges shall be reimbursed by the indemnifying party promptly as they are incurred. An indemnifying party shall not be liable for any settlement of any action or claim effected without its written consent (which consent will not be unreasonably withheld or delayed). No indemnifying party shall, without the prior written consent of each indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding relating to the matters contemplated by this Section 5 (whether or not any indemnified party is a party thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising or that may arise out of such claim, action or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. Notwithstanding the foregoing, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 5(c), the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered

into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

(d) Contribution. In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in the foregoing paragraphs of this Section 5 is applicable in accordance with its terms but for any reason is held to be unavailable from the Company or the Agents, the Company and the Agents shall contribute to the total losses, claims, liabilities, expenses and damages (including, without limitation, any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted, but after deducting any contribution received by the Company from persons other than the Agents, such as persons who control the Company within the meaning of the Act, officers of the Company who signed the Registration Statement and directors of the Company, who also may be liable for contribution) to which the Company and the Agents may be subject in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Agents on the other hand. The relative benefits received by the Company on the one hand and the Agents on the other hand shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the sum of (i) the total compensation to the Agents pursuant to Section 1(a)(ix) (in the case of one or more Agency Transactions hereunder) and (ii) the underwriting discounts and commissions received by the Agents as set forth in the table on the cover page of the Prospectuses. If, but only if, the allocation provided by the foregoing sentence is not permitted by applicable law, the allocation of contribution shall be made in such proportion as is appropriate to reflect not only the relative benefits referred to in the foregoing sentence but also the relative fault of the Company, on the one hand, and the Agents, on the other hand, with respect to the statements or omissions which resulted in such loss, claim, liability, expense or damage, or action in respect thereof, as well as any other relevant equitable considerations with respect to such offering. Such relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Agents, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by an indemnified party as a result of the loss, claim, liability, expense or damage, or action in respect thereof, referred to above in this subsection (d) shall be deemed to include, for purpose of this subsection (d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), the Agents shall not be required to contribute any amount in excess of the sum of (i) the total compensation to the Agents pursuant to Section 1(a)(ix) (in the case of one or more Agency Transactions hereunder) and (ii) the underwriting discounts and commissions received by the Agents as set forth in the table on the cover page of the Prospectuses, and no person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this subsection (d), any person who controls a party to this Agreement within the meaning of the Act will have the same rights to contribution as that party, and each officer of the Company who signed the Registration Statement will have the same rights to contribution as the Company, subject in each case to the provisions hereof. Any party entitled to contribution, promptly after receipt of

notice of commencement of any action against such party in respect of which a claim for contribution may be made under this subsection (d), will notify any such party from whom contribution may be sought, but the omission so to notify will not relieve the party from whom contribution may be sought from any other obligation it may have under this subsection (d). No party will be liable for contribution with respect to any action or claim settled without its written consent (which consent will not be unreasonably withheld).

(e) Survival. The obligations of the Company under this Section 5 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to any affiliate of an Agent and each person, if any, who controls an Agent or any such affiliate within the meaning of the Act; and the obligations of the Agents under this Section 5 shall be in addition to any liability which it may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Act. The indemnity and contribution agreements contained in this Section 5 and the representations and warranties of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of the Agents, (ii) acceptance of any of the Shares and payment therefor or (iii) any termination of this Agreement.

6. Termination.

(a) The Company may terminate this Agreement in its sole discretion at any time upon giving prior written notice to the Agents. Any such termination shall be without liability of any party to any other party, except that (i) with respect to any pending sale, the obligations of the Company, including, without limitation, in respect of compensation of the Agents, shall remain in full force and effect notwithstanding such termination; and (ii) the provisions of Sections 2, 3 (except that if no Shares have been previously sold hereunder, only Section 3(i)), 5, 7(d), 7(f) and 7(k) of this Agreement shall remain in full force and effect notwithstanding such termination.

(b) Any Agent may terminate its obligations under this Agreement solely with respect to such Agent in its sole discretion at any time upon giving prior written notice to the Company. Any such termination shall be without liability of any party to another party, except that (i) with respect to any pending sale, the obligations of the Company, including, without limitation, in respect of compensation of the Agents, shall remain in full force and effect notwithstanding such termination; and (ii) the provisions of Sections 2, 3 (except that if no Shares have been previously sold hereunder, only Section 3(i)), 5, 7(d), 7(f) and 7(k) of this Agreement shall remain in full force and effect notwithstanding such termination.

(c) This Agreement shall remain in full force and effect until the earliest to occur of (A) termination of this Agreement pursuant to subsection (a) or (b) above or otherwise by mutual written agreement of the parties, (B) such date that the aggregate gross sales proceeds of the Shares sold pursuant to this Agreement equals the Maximum Amount and (C) January 8, 2026, in each case except that (i) with respect to any pending sale, the obligations of the Company, including, without limitation, in respect of compensation of the Agents, shall remain in full force and effect notwithstanding such termination; and (ii) the provisions of Sections 2, 3 (except that if no Shares have been previously sold hereunder, only Section 3(i)), 5, 7(d), 7(f) and 7(k) of this Agreement shall remain in full force and effect notwithstanding such termination.

(d) Any termination of this Agreement shall be effective on the date specified in the notice of termination; provided that such termination shall not be effective until the close of business on the date of receipt of such notice by the Agents or the Company, as the case may be. If such termination shall occur prior to the Settlement Date for any sale of Shares, such sale shall settle in accordance with the provisions of Section 1.

Any such notice shall be effective only upon receipt. Any notice under Section 5 may be made by telecopy or telephone, but if so made shall be subsequently confirmed in writing (which may include, in the case of the Agents, electronic mail to any two Authorized Company Representatives).

(b) Consent to Jurisdiction. Each of the parties irrevocably (i) agrees that any legal suit, action or proceeding against the other brought by one party or by any person who controls that party arising out of or based upon this Agreement or the transactions contemplated thereby may be instituted in the courts of the Province of British Columbia located in Vancouver, British Columbia, (ii) waives, to the fullest extent it may effectively do so, any objection which it may now or hereafter have to the laying of venue of any such proceeding and (iii) submits to the exclusive jurisdiction of such courts in any such suit, action or proceeding. To the extent that any party has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service of notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, it hereby irrevocably waives such immunity in respect of its obligations under the above-referenced documents, to the extent permitted by law. The provisions of this Section 7(b) shall survive any termination of this Agreement, in whole or in part.

The foregoing indemnity shall constitute a separate and independent obligation of the Company and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “rate of exchange” shall include any premiums and costs of exchange payable in connection with the purchase of, or conversion into, the relevant currency.

(h) Compliance with USA Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub.
