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 April 4, 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 US$600,000,000 (or the equivalent thereof in Canadian dollars or any other currencies) of common shares, warrants, subscription receipts, debt securities or units comprised of a combination thereof (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 that a receipt has been issued on behalf of itself and 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 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 April 25, 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 as modified by 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).

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 March 30, 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.

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 form of written electronic communication (confirmed promptly by electronic mail in a form substantially similar to Exhibit A hereto (an "Agency Transaction Notice")) from at least one of the individuals listed as an authorized representative 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 NYSE American LLC (the "NYSE American") or the Toronto Stock Exchange (the "TSX") (which may not be a day on which the NYSE American or the TSX, 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 or value of Shares that the Company wishes to sell in the aggregate and on each Trading Day; the minimum price at which the Company is willing to sell the Shares (the "Floor Price"); and the Placement Fee (as defined herein). 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 suspends or terminates the Agency Transaction Notice in accordance with the notice requirements set forth in Section 1(a)(iv) or Section 7, 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. Notwithstanding the foregoing, the Company may not deliver an Agency Transaction Notice to an Agent if the Company has delivered an Agency Transaction Notice which remains in effect to another Agent, unless the Company has terminated the prior Agency Transaction Notice in accordance with the notice requirements set forth in Section 1(a)(iv). 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").

4

(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.

(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 any 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)The Company may, acting through at least one Authorized Company Representative, or the applicable Agent may, upon notice to the other party hereto by telephone (confirmed promptly by electronic mail), suspend an offering of the Shares or terminate an Agency Transaction Notice; provided, however, that such suspension or termination shall not affect or impair the parties' respective obligations with respect to the Shares sold hereunder prior to the giving of such notice, including the parties' obligations set forth under Section 1(a)(viii). Notwithstanding any other provision of this Agreement, during any period in which the Company is in possession of material non-public information with respect to the Company or the Shares, the Company agrees that (i) it will not deliver an Agency Transaction Notice to any Agent and (ii) it will terminate any Agency Transaction Notice that was previously delivered to any Agent.

(v)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.

5

(vi)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 (x) by means of ordinary brokers' transactions that qualify for delivery of the Prospectuses in accordance with Rule 153 of the Rules and Regulations and meet the definition of an "at-the-market-distribution" under Rule 415(a)(4) of the Rules and Regulations and NI 44-102 and are made in compliance with NI 44-102, including, without limitation, sales made directly on the NYSE American and the TSX, or any Canadian marketplace or United States marketplace or (y) 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. Each of the Agents shall not engage in any transactions that are intended to stabilize or maintain the market price of the Shares.

(vii)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 three percent (3%) of the gross offering proceeds of the Shares sold in such Agency Transaction (the "Placement Fee"). The applicable Agent shall provide written confirmation to the Company (which may be provided by email to at least one 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 of Shares 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 American or on any other "marketplace"), (ii) the gross offering proceeds received from such sales, (iii) the Placement Fee payable by the Company to such Agent with respect to such sales (which Placement Fee shall be paid in the same currency as the sale of the Shares to which such Placement Fee pertains) and (iv) the net offering proceeds (being the gross offering proceeds for such sales less the Placement Fee payable for such sales) (the "Net Offering Proceeds").

(viii)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, 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, 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, including the Placement Fee.

6

(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 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 to be issued and sold from time to time 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)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 Securities 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. No stop order suspending the effectiveness of the Registration Statement is in effect and no proceedings for such purpose have been instituted or are pending or, to the knowledge of the Company, are contemplated or threatened by any Canadian Qualifying Authority or similar regulatory authority or the TSX, the NYSE American, the London Stock Exchange ("LSE") 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. "Time of Sale" means the time of the applicable Agent's initial entry into contracts with investors for the sale of such Shares.

7

(b)Ineligible Issuer Status. 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 Securities 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 Securities Act) in connection with the offering of the Shares pursuant to Rules 164, 405 and 433 under the Securities Act, without taking account of any determination by the Commission pursuant to Rule 405 under the Securities Act that it is not necessary that the Company be considered an Ineligible Issuer. Any Permitted Free Writing Prospectus that the Company is required to file pursuant to Rule 433(d) under the Securities Act has been, or will be, filed with the Commission in accordance with the requirements of the Securities Act. Each Permitted Free Writing Prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act or that was prepared by or on behalf of or used or referred to by the Company complies or will comply in all material respects with the requirements of Rule 433 under the Securities Act including timely filing with the Commission or retention where required and legending, and each such Permitted Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the issuance and sale of the Shares did not, does not and will not include any information that conflicted, conflicts with or will conflict with the information contained in the Registration Statement or the Prospectuses, including any document incorporated by reference therein. Except for the Permitted Free Writing Prospectus(es), if any, and electronic road shows, if any, furnished to you before first use, the Company has not prepared, used or referred to, and will not, without your prior consent, prepare, use or refer to, any free writing prospectus.

(c)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 the date of filing thereof with the Commission and at each Time of Sale and Settlement Date, conformed in all material respects 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 the date of filing thereof with the Commission, 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") and 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 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, it being understood and agreed that the only such information furnished by the Agents consists of the information described as such in Section 5(b).

8

(d)Reporting Compliance. The Company is subject to, and is in compliance in all material respects with, the reporting requirements of (i) Section 13 and Section 15(d), as applicable, of the Exchange Act and (ii) Canadian Securities Laws, including, without limitation, National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101").

(e)Preparation of the Financial Statements. The audited consolidated financial statements and related notes and supporting schedules of the Company and its consolidated Subsidiaries (as defined herein) contained in the Registration Statement, the Prospectuses and the Disclosure Package (the "Financial Statements") present fairly in all material respects the financial position, results of operations and cash flows of the Company and its consolidated Subsidiaries, as of the respective dates and for the respective periods to which they apply, and have been prepared in accordance with the International Financial Reporting Standards as issued by the International Accounting Standards Board ("IFRS") applied on a consistent basis, other than where a change in accounting principle has been applied prospectively, throughout the periods involved and the requirements, to the extent applicable, of Regulation S-X and Canadian Securities Laws. All other financial, statistical and market and industry data and forward-looking statements (within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act) contained in the Registration Statement, the Prospectuses and the Disclosure Package are fairly and accurately presented in all material respects, are based on or derived from sources that the Company believes to be reliable and accurate and are presented on a reasonable basis.

(f)Disclosure Controls and Procedures. The Company maintains an effective system of "disclosure controls and procedures" (as defined in Rule 13a-15(e) of the Exchange Act) that is designed to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act or under Canadian Securities Laws is recorded, processed, summarized and reported within the time periods specified in rules and forms of the SEC or any Canadian Qualifying Authorities, as applicable, including controls and procedures designed to ensure that such information is accumulated and communicated to the Company's management as appropriate to allow timely decisions regarding required disclosure. The Company has carried out evaluations of the effectiveness of its disclosure controls and procedures as required by Rule 13a-15 of the Exchange Act and National Instrument 52-109 - Certification of Disclosure in Issuers' Annual and Interim Filings of the CSA ("NI 52- 109"). The statements relating to disclosure controls and procedures made by the principal executive officers (or their equivalents) and principal financial officers (or their equivalents) of the Company in the certifications required by the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith are complete and correct.

9

(g)Independent Accountants. KPMG LLP, who have certified and expressed their opinion with respect to the Financial Statements, are an independent registered public accounting firm with respect to the Company and the Subsidiaries within the applicable rules and regulations adopted by the SEC and the Canadian Qualifying Authorities and as required by the Securities Act, Canadian Securities Laws and Canadian accountant professional standards, as applicable. To the Company's knowledge, KPMG LLP's registration with the Public Company Accounting Oversight Board (United States) or the Canadian Public Accounting Board has not been suspended or revoked and KPMG LLP has not requested such registration to be withdrawn.

(h)No Material Adverse Change. Subsequent to the respective dates as of which information is contained in the Registration Statement, the Prospectuses and the Disclosure Package, except as disclosed in the Registration Statement, the Prospectuses and the Disclosure Package, (i) none of the Company or its Subsidiaries has incurred any liabilities, direct or contingent, including without limitation any losses or interference with its business from fire, explosion, flood, earthquakes, accident or other calamity, whether or not covered by insurance, or from any strike, labor dispute or court or governmental action, order or decree, that are material, individually or in the aggregate, to the Company and the Subsidiaries, taken as a whole, (ii) there has not been any material decrease in the capital stock or any material increase in any short-term or long-term indebtedness of the Company or the Subsidiaries, or any payment of or declaration to pay any dividends or any other distribution with respect to the Company, and (iii) there has not been any material adverse change, or any development that could reasonably be expected to result in a material adverse change, in the properties, business, prospects, operations, earnings, assets, liabilities or condition (financial or otherwise) of the Company and the Subsidiaries, taken as a whole (each of clauses (i), (ii) and (iii), a "Material Adverse Change").

(i)Subsidiaries. Each corporation, partnership or other entity in which the Company, directly or indirectly through any of its subsidiaries, owns more than fifty percent (50%) of any class of equity securities or interests is listed on Schedule 2 attached hereto (the "Subsidiaries"). The Company, directly or indirectly through Subsidiaries, beneficially owns the percentage indicated in Schedule 2 of the issued and outstanding shares in the capital of the Subsidiaries, free and clear of all liens, security interests, mortgages, pledges, charges, equities, claims or restrictions on transferability or encumbrances of any kind (collectively, "Liens") other than Liens on the shares of Gibraltar Mines Ltd. ("Gibraltar Mines"), Curis Holdings (Canada) Ltd. ("Curis") and Florence Holdings Inc. granted pursuant to the Credit Facilities and to Osisko Gold Royalties Ltd. pursuant to Osisko's silver stream (the "Osisko Silver Stream") on the Gibraltar Mine (as defined below) (collectively, the "Permitted Encumbrances"). All of such shares in the capital of the Subsidiaries have been duly authorized and validly issued and are fully paid and non-assessable. None of the outstanding securities of the Subsidiaries was issued in violation of the pre-emptive or similar rights of any security holder of such Subsidiaries. Except in respect of the right of Mitsui & Co. (U.S.A.) Inc. to acquire up to a 10% interest in Florence Copper LLC (which is disclosed in the Registration Statement, the Prospectuses and the Disclosure Package), there exist no options, warrants, purchase rights, or other contracts or commitments that could require the Company to sell, transfer or otherwise dispose of any securities of any Subsidiary.

(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.

This indemnity will be in addition to any liability that the Company might otherwise have.

39

(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 Securities 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.

(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. 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. 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 (x) includes an unconditional release of each indemnified party from all liability arising or that may arise out of such claim, action or proceeding and (y) 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.

40

(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 Securities 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 to the sum of (i) the total compensation to actually received by the Agents pursuant to Section 1(a)(vii) (in the case of one or more Agency Transactions hereunder) and (ii) the underwriting discounts and commissions actually 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 Section 5(d) shall be deemed to include, for purpose of this Section 5(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 Section 5(d), no Agent shall not be required to contribute any amount in excess of the sum of (i) the total compensation actually received by such Agent pursuant to Section 1(a)(vii) (in the case of one or more Agency Transactions hereunder) and (ii) the underwriting discounts and commissions actually received by such Agent 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 5(d), any person who controls a party to this Agreement within the meaning of the Securities 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 Section 5(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 Section 5(d) unless, and only to the extent that, such omission results in any increase in the liability to contribute pursuant to this Section 5(d) that the party would not otherwise have had the other contributing party given notice. 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).

41

(e)Beneficiaries. 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 Securities 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 Securities Act.

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 the 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 (Representations and Warranties of the Company), 3 (Agreements of the Company) (except that if no Shares have been previously sold hereunder, only Section 3(h) (Reimbursement of Certain Expenses)), 5 (Indemnification), 7(d) (Survival of Representations and Warranties), 7(f) (Governing Law) and 7(m) (Waiver of Jury Trial) of this Agreement shall remain in full force and effect notwithstanding such termination.

42

(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 (Representations and Warranties of the Company), 3 (Agreements of the Company) (except that if no Shares have been previously sold hereunder, only Section 3(h) (Reimbursement of Certain Expenses)), 5 (Indemnification), 7(d) (Survival of Representations and Warranties), 7(f) (Governing Law) and 7(m) (Waiver of Jury Trial) 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 (i) termination of this Agreement pursuant to Section 6(a) or 6(b) above or otherwise by mutual written agreement of the parties, (ii) such date that the aggregate gross sales proceeds of the Shares sold pursuant to this Agreement equals the Maximum Amount and (iii) May 26,2025, in each case except that (x) 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 (y) the provisions of Sections 2 (Representations and Warranties of the Company), 3 (Agreements of the Company) (except that if no Shares have been previously sold hereunder, only Section 3(h) (Reimbursement of Certain Expenses)), 5 (Indemnification), 7(d) (Survival of Representations and Warranties), 7(f) (Governing Law) and 7(m) (Waiver of Jury Trial) 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.

The provisions of this Section 7(b) shall survive any termination of this Agreement, in whole or in part.

45

(c)No Third Party Beneficiaries. The Company acknowledges and agrees that the Agents are acting solely in the capacity of arm's length contractual counterparties to the Company with respect to the offering of Shares contemplated hereby (including in connection with determining the terms of the offering) and not as financial advisors or fiduciaries to, or agents of, the Company or any other person. Additionally, the Agents are not advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Agents shall have no responsibility or liability to the Company with respect thereto. Any review by the Agents of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Agents and shall not be on behalf of the Company.

(d)Survival of Representations and Warranties. All representations, warranties and agreements of the Company contained herein or in certificates or other instruments delivered pursuant hereto shall remain operative and in full force and effect regardless of any investigation made by or on behalf of the Agents or any of their controlling persons and shall survive delivery of and payment for the Shares hereunder.

(e)Disclaimer of Fiduciary Relationship. The Company acknowledges and agrees that (i) the purchase and sale of the Shares pursuant to this Agreement, including the determination of the terms of the offering and any related discounts and commissions, is an arm's-length commercial transaction between the Company, on the one hand, and the Agents, on the other hand, (ii) in connection with the offering contemplated by this Agreement and the process leading to such transaction, the Agents owe no fiduciary duties to the Company or its securityholders, creditors, employees or any other party, (iii) the Agents have not assumed nor will they assume any advisory or fiduciary responsibility in favor of the Company with respect to the offering of the Shares contemplated by this Agreement or the process leading thereto (irrespective of whether the Agents or their affiliates have advised or are currently advising the Company on other matters) and the Agents have no obligation to the Company with respect to the offering of the Shares contemplated by this Agreement except the obligations expressly set forth in this Agreement, (iv) the Agents and their affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and (v) the Agents have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated by this Agreement and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

(f)Governing Law. THIS AGREEMENT, AND ANY DISPUTE, CLAIM OR CONTROVERSY ARISING UNDER OR RELATED TO THIS AGREEMENT, SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE PROVINCE OF BRITISH COLUMBIA APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH PROVINCE. Each party hereto hereby irrevocably submits for purposes of any action arising from this Agreement brought by any other party hereto to the jurisdiction of the courts of the Province of British Columbia.

46

(g)Judgment Currency. The Company agrees to indemnify each Agent, their directors, officers, affiliates and each person, if any, who controls an Agent within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any loss incurred by the Agents as a result of any judgment or order being given or made for any amount due hereunder and such judgment or order being expressed and paid in a currency (the "judgment currency") other than U.S. dollars and as a result of any variation as between (i) the rate of exchange at which the U.S. dollar amount is converted into the judgment currency for the purpose of such judgment or order, and (ii) the rate of exchange at which such indemnified person is able to purchase U.S. dollars with the amount of the judgment currency actually received by the indemnified person. 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. L. 107-56 (signed into law October 26, 2001)), the Agents are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Agents to properly identify their respective clients.

(i)TMX Group. The Company hereby acknowledges that certain of the Agents, or affiliates thereof, own or control an equity interest in TMX Group Limited ("TMX Group") and may have a nominee director serving on the TMX Group's board of directors. As such, such investment dealers may be considered to have an economic interest in the listing of securities on any exchange owned or operated by TMX Group, including the Toronto Stock Exchange, the TSX and the TSX Alpha Exchange. No person or company is required to obtain products or services from TMX Group or its affiliates as a condition of any such dealer supplying or continuing to supply a product or service.

(j)Recognition of the U.S. Special Resolution Regimes. (i) In the event that any Agent that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Agent of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States and (ii) in the event that any Agent that is a Covered Entity or a BHC Act Affiliate of such Agent becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Agent are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States. For the purposes of this Section 7(j), a "BHC Act Affiliate" has the meaning assigned to the term "affiliate" in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k). "Covered Entity" means any of the following: (i) a "covered entity" as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (ii) a "covered bank" as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (iii) a "covered FSI" as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b). "Default Right" has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable. "U.S. Special Resolution Regime" means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

47

(k)Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument, and may be delivered by facsimile transmission or by electronic delivery of a portable document format (PDF) file.

(l)Survival of Provisions Upon Invalidity of Any Single Provision. In case any provision in this Agreement shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

(m)Waiver of Jury Trial. Each of the Company and each of the Agents hereby irrevocably waives any right it may have to a trial by jury in respect of any claim based upon or arising out of this Agreement or the transactions contemplated hereby or thereby.

(n)Successors and Assigns. This Agreement will insure to the benefit of and be binding upon the parties hereto, and to the benefit of the employees, officers and directors and controlling persons referred to in Section 5, and in each case their respective successors, and no other person will have any right or obligation hereunder. No party may assign its rights or obligations under this Agreement without the prior written consent of the other parties. The term "successors" shall not include any purchaser of the Shares as such from the Agents merely by reason of such purchase.

(o)Titles and Subtitles. The titles of the sections and subsections of this Agreement are for convenience and reference only and are not to be considered in construing this Agreement.

(p)Entire Agreement. Other than the terms set forth in each Agency Transaction Notice delivered hereunder, this Agreement embodies the entire agreement and understanding between the parties hereto and supersedes all prior agreements and understandings relating to the subject matter hereof. This Agreement may not be amended or otherwise modified or any provision hereof waived except by an instrument in writing signed by the Agents and the Company. Notwithstanding the foregoing, any party to this Agreement may update its list of representatives on Schedule 1 or their contact information by notice to the other parties to this Agreement given in the manner provided for by this Agreement.

8.The execution and delivery of the Agreement by the Company, the performance by the Company of its obligations thereunder and the issuance and sale of the Shares as contemplated in the Agreement will not (i) result in a breach or constitute a default under, or (ii) create a state of facts which, after notice or lapse of time or both, will result in a breach or constitute a default under: (A) the notice of articles or articles of the Company or any resolution of any of the directors (or committees of directors) or shareholders of the Company; or (B) any applicable corporate or securities laws of the Province of British Columbia or the federal laws of Canada applicable therein, or any applicable stock exchange rules or regulations.

B-1

9.When the Shares are issued and paid for in full in accordance with the terms of the Agreement, the Shares will be validly issued as fully paid and non-assessable Common Shares.

10.Subject to the qualifications, limitations, restrictions and assumptions set out therein, the statements in the Canadian Prospectus Supplement under the headings "Certain Canadian Federal Income Tax Considerations" and "Eligibility for Investment", insofar as such statements constitute statements of law, constitute accurate general summaries of the principal Canadian federal income tax considerations under the Tax Act described therein generally applicable to holders described therein.

11.The Company is a "reporting issuer" in each of the Canadian Qualifying Jurisdictions as defined under Canadian Securities Laws and, as of the date hereof, is not noted on the Reporting Issuers Lists to be in default.

12.All necessary documents have been filed, all requisite proceedings have been taken and all approvals, permits, consents and authorizations of the Canadian Qualifying Authorities in each of the Canadian Qualifying Jurisdictions have been obtained by the Company to qualify the distribution of the Shares in each of the Canadian Qualifying Jurisdictions through persons who are duly registered in the category of investment dealer under the Canadian Securities Laws and who have complied with the relevant provisions of such Canadian Securities Laws and the terms of such registrations.

13.No consent, approval or authorization or order, of or registration, qualification, recording or filing with any Governmental Authority is required for the issuance, sale and delivery of the Shares, except such as have been made or obtained, other than the final approval of the TSX with respect to the listing and posting for trading of the Shares.

14.The listing on the TSX of the Shares, when issued and paid for in full in accordance with the terms of the Agreement, has been conditionally approved by the TSX, subject to the Company fulfilling all of the requirements of the TSX, as set forth in the TSX Approval.

EXHIBIT C

Form of Opinion of
U.S. Counsel to the Company

1.The statements in the U.S. Prospectus under the heading "Certain Income Tax Considerations," to the extent that they constitute summaries of United States federal law or regulation or legal conclusions, have been reviewed by us and fairly summarize the matters described under that heading in all material respects.

2.The Registration Statement and the U.S. Prospectus, as of their respective effective or issue times, appear on their face to be appropriately responsive in all material respects to the requirements of the Securities Act and the rules and regulations of the Commission under the Securities Act, except for the financial statements and other financial data included or incorporated by reference in or omitted from either of them, as to which we express no opinion. The Form F-X, as of its date, appears on its face to be appropriately responsive in all material respects to the requirements of the Securities Act and the rules and regulations of the Commission under the Securities Act. We have assumed for purposes of this paragraph, (i) the compliance of the Canadian Prospectus and the documents incorporated by reference therein with the requirements of British Columbia securities laws, as interpreted and applied by the British Columbia Securities Commission and (ii) that the exhibits to the Registration Statement and the documents incorporated by reference in the U.S. Prospectus include all reports or information that in accordance with the requirements of British Columbia securities laws, as interpreted and applied by the British Columbia Securities Commission, must be made publicly available in connection with the offering of the Shares. We understand that such matters are covered in the opinion of McMillan LLP furnished to you today.

3.The issuance and sale of the Shares by the Company, the execution and delivery by the Company of the Equity Distribution Agreement and the performance by the Company of its obligations thereunder will not violate those laws, rules and regulations of the United States of America and the State of New York ("Applicable Law"), in each case which in our experience are normally applicable to the transactions of the type contemplated by the Equity Distribution Agreement. For purposes of this letter, the term "Applicable Law" does not include federal securities laws (except for purposes of the opinion expressed in paragraph 3 above) or state securities laws, anti-fraud laws, or any law, rule or regulation that is applicable to the Company, the Equity Distribution Agreement or the transactions contemplated thereby solely because such law, rule or regulation is part of a regulatory regime applicable to any party to the Equity Distribution Agreement or any of its affiliates due to the specific assets or business of such party or such affiliate. We express no opinion where the violation could not reasonably be expected to have a material adverse effect on the Company and its subsidiaries taken as a whole.

C-1
