(5) The Company shall in good faith discuss with the Underwriters any fact or change in circumstances (actual, anticipated, contemplated or threatened, financial or otherwise) which is of such a nature that there is reasonable doubt whether written notice need be given under this Section 5.

Section 6 Purchase, Sale, Payment and Delivery of the Offered Shares

The Company hereby confirms its agreement with the Underwriters concerning the purchase and sale of the Offered Shares as follows:

(1) Public Offering of the Offered Shares. The Underwriters hereby advise the Company that they intend to offer for sale to the public, on the terms set forth in the Offering Documents, the Offered Shares as soon after this Agreement has been executed as the Underwriters, in their sole judgment, have determined is advisable and practicable. After the Underwriters have made a reasonable effort to sell all of the Offered Shares at the Offering Price, the purchase price of the Offered Shares may be decreased by the Underwriters and may be further changed from time to time to an amount not greater than the Offering Price, and the compensation realized by the Underwriters will be decreased by the amount that the aggregate price paid by purchasers for the Offered Shares is less than the gross proceeds paid by the Underwriters to the Company. Any such decrease will not affect the proceeds to be received by the Company.

(2) The Closing Date in respect of the Offered Shares. Payment of the Offering Price for the Firm Shares, and if applicable, any Additional Shares, shall be made to the Company by wire transfer against delivery of the Firm Shares and, if applicable, Additional Shares, to the Underwriters, through the facilities of CDS designated by Eight Capital, and such payment and delivery shall be made by 8:00 a.m. (Toronto time), on April 30, 2024 (respectively, the “Closing Time” and the “Closing Date”) (unless another time and date shall be agreed to by the Lead Underwriter and the Company). The Firm Shares, and the Additional Shares, if any, shall be registered in such names and in such denominations as specified by Eight Capital.

(3) Over-Allotment Option. The Over-Allotment Option may be exercised by the Lead Underwriter (on its own behalf and on behalf of the Underwriters) at any time, in whole or in part by delivering notice to the Company not later than 5:00 p.m. (Vancouver time) on the 30th day after the Closing Date, which notice will specify the number of Additional Shares to be purchased by the Underwriters and the date (the “Option Closing Date”) and

- 16 - Underwriting Agreement

time (the “Option Closing Time”) on and at which such Additional Shares are to be purchased. Such Option Closing Date may be the same as (but not earlier than) the Closing Date and will not be earlier than two Business Days nor later than five Business Days after the date of delivery of such notice (except to the extent a shorter or longer period shall be agreed to by the Company). Subject to the terms of this Agreement, upon the Lead Underwriter furnishing this notice, the Underwriters will be committed to purchase, and the Company will be committed to issue and sell in accordance with and subject to the provisions of this Agreement, the number of Additional Shares indicated in the notice and in accordance with the percentages set forth in Section 17 opposite the name of each Underwriter. Additional Shares may be purchased by the Underwriters solely for the purposes of satisfying over-allotments and for market stabilization purposes.

(4) Delivery of the Offered Shares and Closing Mechanics. The Company shall deliver, or cause to be delivered, to the Underwriters in accordance with Section 6(2) and this Section 6(4), the Firm Shares, and if applicable, the Additional Shares, at the Closing Time, against the irrevocable release of a wire transfer of immediately available funds for the amount of the Offering Price therefor. The Offered Shares shall be registered in such names and denominations as Eight Capital shall have requested at least one full Business Day prior to the Closing Date. Deliveries of the documents described in Section 15(1) hereof with respect to the purchase of the Offered Shares shall be made at the offices of Cassels Brock & Blackwell LLP in Vancouver, British Columbia, or at such other place as Eight Capital and the Company may agree, including electronically, at the Closing Time on the Closing Date. In the event that the Over-Allotment Option is exercised after the Closing Date in accordance with its terms, the closing of the issuance and sale of that number of Additional Shares in respect of which the Underwriters are exercising the Over-Allotment Option shall take place at the Option Closing Time at the offices of Cassels Brock & Blackwell LLP or at such other place as Eight Capital and the Company may agree, including electronically. At the Option Closing Time, the Company shall issue to the Underwriters that number of Additional Shares in respect of which the Underwriters are exercising the Over-Allotment Option and deposit with CDS or its nominee, if requested by Eight Capital, the Additional Shares electronically through the non-certificated inventory system of CDS against payment of C$1.90 per Additional Share by wire transfer payable to the Company or as otherwise directed by the Company. Time shall be of the essence, and delivery at the time and place specified in this Agreement is a further condition to the obligations of the Underwriters.

Section 7 Regulatory Approvals

The Company will make all necessary filings, obtain all necessary consents and approvals (if any) and pay all filing fees required to be paid in connection with the transactions contemplated by this Agreement. The Company will qualify the Offered Shares for offering and sale under the Applicable Securities Laws of the Offering Jurisdictions and in such other jurisdictions as the Underwriters may designate and maintain such qualifications in effect for so long as required for the Distribution of the Offered Shares; provided, however, that (i) the Company shall not be obligated to make any material filing, file any prospectus, registration statement or similar document, consent to service of process, or qualify as a foreign corporation or as a dealer in securities in any of such other jurisdictions, or subject itself to taxation in respect of doing business

The Company has established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15 and 15d-15) for the Company and designed such disclosure controls and procedures to ensure that material information relating to the Company and the Material Subsidiary is made known to the certifying officers by others within those entities, particularly during the Company’s fiscal year ended December 31, 2023. The Company’s certifying officers have evaluated the effectiveness of the Company’s controls and procedures as of a date within 120 days prior to the filing date of the Form 40-F for the fiscal year ended December 31, 2023 (such date, the “Evaluation Date”). The Company presented in its Form 40-F for the fiscal year ended December 31, 2023 the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date and the disclosure controls and procedures are effective.

(b) any omission or alleged omission to state in any Offering Document, any Issuer Free Writing Prospectus, any marketing materials or any Supplementary Material related thereto, or any certificate or other document of the Company or any officer of the Company or the Material Subsidiary delivered hereunder or pursuant hereto any material fact, required to be stated therein or necessary to make any statement therein not misleading in light of the circumstances under which it was made;

(c) any order made or any inquiry, investigation or proceedings commenced or threatened by any securities commission, stock exchange or other Governmental Authority based upon any actual or alleged untrue statement, omission or misrepresentation in any Offering Document, any Issuer Free Writing Prospectus, any marketing materials or any Supplementary Material or based upon any actual or alleged failure to comply with Canadian Securities Laws or U.S. Securities Laws, preventing or restricting the trading in of the Firm Shares or Additional Shares or the distribution of the Offered Shares or any other securities of the Company;

(d) the non-compliance or alleged non-compliance by the Company with any requirement of Canadian Securities Laws or U.S. Securities laws in any of the Qualifying Jurisdictions or in the United States or any state therein in connection with the transactions herein contemplated including the Company’s non-compliance or alleged non-compliance with any statutory requirement to make any document available for inspection; or

(e) any breach of any representation or warranty, covenant, obligation or agreement of the Company contained herein or in any certificate or other document of the Company or of any officers of the Company or the Material Subsidiary delivered hereunder or pursuant hereto or the failure of the Company to comply with any of its obligations hereunder,

provided, however, that the foregoing indemnity (i) shall not apply to any loss, liability, claim, damage or expense to the extent arising solely out of any untrue statement or omission or alleged untrue statement or omission made solely in reliance upon and in conformity with written information relating to the Underwriters furnished to the Company by the Underwriters expressly for use in the Offering Documents, or any such amendment or supplement thereto, or any Issuer Free Writing Prospectus, and (ii) shall cease to apply to an Indemnified Party claiming indemnity, if and to the extent that a court of competent jurisdiction in a final judgment from which no appeal can be made or a Governmental Authority in a final ruling from which no appeal can be made determines that any loss, liability, claim, damage or expense resulted primarily and directly from the gross negligence or willful misconduct of such Indemnified Party claiming indemnity. For greater certainty, the Company and the Underwriters agree that they do not intend that any failure by the Underwriters to conduct such reasonable investigation as necessary to provide the Underwriters with reasonable grounds for believing the applicable document contained no misrepresentation shall constitute “gross negligence” or “willful misconduct” for purposes of this Section 10 or otherwise disentitle the Underwriters from indemnification hereunder.

- 37 - Underwriting Agreement

(2) If any matter or thing contemplated by this Section 10 (any such matter or thing being hereinafter referred to as a “Claim”) is asserted against an Indemnified Party, the Indemnified Party shall notify the Indemnifying Party as soon as practicable, of such Claim to the extent allowable by Applicable Law (provided, however, that failure to provide such notice shall not affect the Indemnified Party’s right to indemnification hereunder, except (and only) to the extent of material prejudice (through the forfeiture of substantive rights and defenses) to the Indemnifying Party therefrom) and the Indemnifying Party shall be entitled (but not required) to assume the defence of any suit, action or proceeding brought to enforce such Claim; provided, however, that the defence shall be conducted through legal counsel acceptable to the Indemnified Party and that no admission of liability or settlement of any such Claim may be made by the Indemnifying Party or the Indemnified Party without the prior written consent of the other.

(3) In any such Claim, the Indemnified Party shall have the right to retain separate counsel to act on its behalf provided that the fees and disbursements of such counsel shall be paid by the Indemnified Party unless:

(a) the Indemnifying Party fails to assume the defence of such Claim on behalf of the Indemnified Party within five Business Days of receiving detailed notice thereof or, having assumed such defence, has failed to engage counsel promptly or who is acceptable to the Indemnified Parties, or has failed to pursue it diligently;

(b) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of the other counsel; or

(c) the named parties to the Claim (including any added, third parties or interpleaded parties) include the Indemnifying Party, and the Indemnifying Parties has been advised by counsel (including internal counsel) that there are legal defences available to such Indemnified Party that are different or in addition to those available to the Indemnifying Party, that representation of the Indemnified Party by counsel for the Indemnifying Party is inappropriate as a result of the potential or actual conflicting interests of those represented, or where in such Indemnified Party’s reasonable judgment, the Claim gives rise to a conflict of interest between the Indemnifying Party and such Indemnified Party; in each of cases Section 10(3)(a), Section 10(3)(b) and Section 10(3)(c), the Indemnifying Party will not have the right to assume the defence of the suit on behalf of such Indemnified Party, but the Indemnifying Party will be liable to pay the fees and expenses of separate counsel for all Indemnified Parties and, in addition, of local counsel in each applicable jurisdiction. Notwithstanding the foregoing, no settlement may be made by an Indemnified Party without the prior written consent of the Indemnifying Party, which consent will not be unreasonably withheld, conditioned or delayed.

(4) The Company hereby acknowledges and agrees that the information furnished to the Company by the Underwriters expressly for use in the Offering Documents, any Issuer Free Writing Prospectus or marketing materials (or any amendment or supplement to any of the foregoing), the Time of Sale Prospectus, or any “issuer information” (as defined in

- 38 - Underwriting Agreement

Rule 433), or any “road show” (as defined in Rule 433) that does not constitute an Issuer Free Writing Prospectus, consists exclusively of the following information appearing under the caption “Plan of Distribution” in the Offering Documents: (i) the information regarding the Underwriting Fee appearing in the second paragraph under such caption and (ii) the information regarding stabilization appearing in the tenth paragraph under such caption (but only insofar as such information concerns the Underwriters).

Section 11 Contribution

(1) In order to provide for a just and equitable contribution in circumstances in which the indemnity provided in Section 10(1) would otherwise be available in accordance with its terms but is, for any reason, held to be unavailable to or unenforceable by the Indemnified Party or enforceable otherwise than in accordance with its terms or is insufficient to hold the Indemnified Party harmless, the Indemnifying Party shall contribute to the aggregate of all claims, expenses, costs and liabilities and all losses (other than loss of profits in connection with the distribution of the Offered Shares) of the nature contemplated in this Section 11 and suffered or incurred by the Indemnified Parties in such proportions as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the distribution of the Offered Shares as well as the relative fault of the parties in connection with the Claim or Claims which resulted in such claims, expenses, costs, damages, liabilities or losses, as well as any other equitable considerations determined by a court of competent jurisdiction; provided that: (i) the Underwriters shall not in any event be liable to contribute, in the aggregate, any amount in excess of the aggregate fee or any portion thereof actually received by the Underwriters hereunder; and (ii) no party who has been determined by a court of competent jurisdiction in a final judgment that has become non-appealable to have engaged in any fraud, fraudulent misrepresentation, wilful misconduct or gross negligence in connection with the Claim or Claims which resulted in such claims, expenses, costs, damages, liabilities or losses shall be entitled to claim contribution from any person who has not been so determined to have engaged in such fraud, fraudulent misrepresentation or gross negligence in connection with such Claim or Claims.

(2) The rights of contribution and indemnity provided in this Section 11 shall be in addition to and not in derogation of any other right to contribution and indemnity which the Underwriters may have by statute or otherwise at law.

(3) In the event that any Indemnifying Party is held to be entitled to contribution from the Underwriters under the provisions of any Applicable Law, the Indemnifying Party shall be limited to contribution in an amount not exceeding the lesser of:

(a) the portion of the full amount of the loss or liability giving rise to such contribution for which the Underwriters is responsible, as determined above; and

(b) the amount of the aggregate fee actually received by the Underwriters from the Indemnifying Party hereunder, provided that the Underwriters shall not be required to contribute more than the fee actually received by the Underwriters.

- 39 - Underwriting Agreement

(4) If the Underwriters have reason to believe that a claim for contribution may arise, they shall give the Indemnifying Party notice thereof in writing, but failure to notify the Indemnifying Party shall not relieve the Indemnifying Party of any obligation which it may have to the Underwriters under this Section 11, except (and only) to the extent of material prejudice (through the forfeiture of substantive rights and defenses) to the Indemnifying Party therefrom.

(5) With respect to Section 10 and this Section 11, the Company acknowledges and agrees that the Underwriters are contracting on its own behalf and as agent for their respective affiliates, directors, officers, employees and agents, and each person, if any, controlling any Underwriters or any of their subsidiaries and each shareholder of any Underwriter. Accordingly, the Company hereby constitutes the Underwriters as agents for each person who is entitled to the covenants of the Company contained in Section 10 and this Section 11 and is not a party hereto and the Underwriters agree to accept such agents and to hold in trust for and to enforce such covenants on behalf of such persons.

Such delivery shall also confirm that the Company consents to the use by the Underwriters and Selling Firms of the Offering Documents in connection with the Distribution of the Offered Shares in compliance with the provisions of this Agreement.

(3) The Underwriters’ Review of Proposed Amendments and Supplements. Prior to amending or supplementing any of the Offering Documents (including any amendment or supplement through incorporation by reference of any document), the Company shall furnish to the Underwriters for review, a reasonable amount of time prior to the proposed time of filing or use thereof, a copy of each such proposed amendment or supplement, and the Company shall not file or use any such proposed amendment or supplement without the Underwriters’ consent which shall not be unreasonably delayed, conditioned or withheld.

(4) Free Writing Prospectuses. The Company shall furnish to the Underwriters for review, a reasonable amount of time prior to the proposed time of filing or use thereof, a copy of each proposed Issuer Free Writing Prospectus or any amendment or supplement thereto to be prepared by or on behalf of, used by, or referred to by the Company and the Company shall not file, use or refer to any proposed free writing prospectus or any amendment or supplement thereto without the Underwriters’ consent which shall not be unreasonably delayed, conditioned or withheld. The Company shall furnish to the Underwriters, without charge, as many copies of any free writing prospectus prepared by or on behalf of, or used by, the Company as the Underwriters may reasonably request. If during the Prospectus Delivery Period there occurred or occurs an event or development as a result of which any free writing prospectus prepared by or on behalf of, used by, or referred to by the Company conflicted or would conflict with the information contained in the Registration Statement or included or would include an untrue statement of a material fact or, omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company shall promptly amend or supplement such free writing prospectus to eliminate or correct such conflict or so that the statements in such free writing prospectus as so amended or supplemented will not include an 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 prevailing at such subsequent time, not misleading, as the case may be; provided, however, that prior to amending or supplementing any such free writing

(5) Filing of Underwriters Free Writing Prospectuses. The Company shall not take any action that would result in any Underwriters or the Company being required to file with the SEC pursuant to Rule 433(d) under the Securities Act a free writing prospectus prepared by or on behalf of the Underwriters that the Underwriters otherwise would not have been required to file thereunder.

(6) Amendments and Supplements to Offering Documents. If any time prior to the Closing Date any event shall occur or condition shall exist as a result of which the Offering Documents, as amended or supplemented, would include an 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 when delivered to a prospective purchaser, not misleading, or if, in the reasonable opinion of counsel for the Company or the Underwriters, it is necessary to amend or supplement the Offering Documents to comply with Applicable Law, including the Securities Act, the Company shall (subject to Section 12(3) and Section 12(4)) forthwith prepare, file with the SEC and the Canadian Commissions and furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Offering Documents so that the statements in the Offering Documents as so amended or supplemented will not include an 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 when delivered to a prospective purchaser, not misleading, or so that the Offering Documents, as amended or supplemented, will comply with Applicable Law including the Securities Act and the Canadian Securities Laws.

(9) Stock Exchange Listing. The Company shall use its best efforts to obtain the conditional approval for the listing of the Offered Shares on the TSX by the Closing Time, subject only

- 43 - Underwriting Agreement

to the official notice of issuance (the “Standard Listing Condition”), and the Company will use its best efforts to have the Offered Shares listed and admitted and authorized for trading on the NYSE American by the Closing Time.

(10) Blue Sky Compliance. The Company shall cooperate with the Lead Underwriter and counsel for the Underwriters to qualify or register the Offered Shares for sale under (or obtain exemptions from the application of) U.S. Securities Laws, Canadian Securities Laws, or other foreign laws of jurisdictions designated by Eight Capital, shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Offered Shares. The Company shall not be required to qualify as a foreign corporation or to take any action that would subject it to general service of process in any jurisdiction in which it is not presently qualified or where it would be subject to taxation as a foreign corporation (except service of process with respect to the offering and sale of the Offered Shares). The Company will advise the Lead Underwriter promptly of the suspension of the qualification or registration of (or any exemption relating to) the Offered 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 best efforts to obtain the withdrawal thereof at the earliest possible moment.

(14) Periodic Reporting Obligations. Prior to the completion of the Distribution of the Offered Shares, the Company will file all reports and documents required to be filed with or furnished to the Canadian Commissions and the SEC pursuant to Applicable Securities Laws.

(15) Agreement Not to Issue, Offer or Sell Additional Shares. Except as contemplated by this Agreement, the Company will not, without the prior written consent of the Lead Underwriter (not to be unreasonably withheld or delayed), directly or indirectly issue, offer, pledge, sell, contract to sell, contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer, lend or dispose of directly or indirectly, any Common Shares or securities or other financial instruments convertible into or having the right to acquire Common Shares or enter into any agreement

- 44 - Underwriting Agreement

or arrangement under which the Company would acquire or transfer to another, in whole or in part, any of the economic consequences of ownership of Common Shares, whether that agreement or arrangement may be settled by the delivery of Common Shares or other securities or cash, or agree to become bound to do so, or disclose to the public any intention to do so, during the period from the date hereof and ending 90 days following the Closing Date; provided that, notwithstanding the foregoing, the Company may issue Common Shares or securities convertible into Common Shares in conjunction with (i) the grant or exercise or vesting of stock options, restricted share units, deferred share units and other similar issuances pursuant to the equity incentive plans of the Company and other stock-based compensation arrangements including, for greater certainty the sale of any shares issued thereunder; (ii) the exercise or conversion of outstanding convertible securities; (iii) any transaction with an arm’s length third party whereby the Company directly or indirectly (a) acquires shares or assets of a business or (b) issues securities in connection with a joint venture or other strategic investment in or by the Company; and (iv) any obligations in respect of existing agreements. In addition, from the date hereof and ending 90 days following the Closing Date, the Company shall not, without the prior written consent of the Lead Underwriter (not to be unreasonably withheld or delayed), file a prospectus under Canadian Securities Laws or a registration statement under the Securities Act in connection with any transaction by the Company or any person that is prohibited pursuant to the foregoing, except pursuant to the Offering and for registration statements on Form S-8 relating to employee benefit plans.

(16) Investment Limitation. The Company shall not invest or otherwise use the proceeds received by the Company from its sale of the Offered Shares in such a manner as would require the Company or the Material Subsidiary to register as an investment company under the Investment Company Act.

(17) No Stabilization or Manipulation; Compliance with Regulation M. The Company will not take, directly or indirectly, any action designed to or that might be reasonably expected to cause or result in stabilization or manipulation of the price of the Common Shares or any other reference security, whether to facilitate the sale or resale of the Offered Shares or otherwise, and the Company will, and shall cause each of its affiliates to, comply with all applicable provisions of Regulation M. If the limitations of Rule 102 of Regulation M (“Rule 102”) do not apply with respect to the Offered Shares or any other reference security pursuant to any exception set forth in Section (d) of Rule 102, then promptly upon notice from the Lead Underwriter (or, if later, at the time stated in the notice), the Company will, and shall cause each of its affiliates to, comply with Rule 102 as though such exception were not available but the other provisions of Rule 102 (as interpreted by the SEC) did apply.

(18) Press Releases/Announcements. Prior to the Closing Date, the Company shall not, without the Lead Underwriter’s prior written consent, which shall not be unreasonably delayed, conditioned or withheld, issue any press releases or other communications directly or indirectly relating to the Offering and shall not hold any press conferences with respect to the Company or the Material Subsidiary, the financial condition, results of operations, business, properties, assets, or liabilities of the Company or the Material Subsidiary, or with respect to the Offering. Notwithstanding the foregoing, nothing contained in this

- 45 - Underwriting Agreement

subsection shall prevent the Company from issuing a press release forthwith in the event that the Company’s counsel advises that it is necessary in order to comply with Applicable Law or the rules or requirements of the TSX or the NYSE American, or from issuing a press release or holding an analyst call in the normal course in connection with the release of financial results.

Section 13 All Terms to be Conditions

Any breach or failure to comply with any of the conditions set out in this Agreement shall entitle the Underwriters (or any one of them) to terminate their obligation to purchase the Offered Shares, by written notice to that effect given to the Company at or prior to the Closing Time or the Option Closing Time, as applicable. It is understood that the Underwriters (or any one of them) may waive, in whole or in part, or extend the time for compliance with, any of such terms and conditions without prejudice to the rights of the Underwriters in respect of any such terms and conditions or any other or subsequent breach or non-compliance, provided that to be binding on such Underwriter any such waiver or extension must be in writing and signed by such Underwriter.

- 46 - Underwriting Agreement

(c) there should occur or commence or be announced or threatened any inquiry, action, suit, investigation or other proceeding (whether formal or informal) or any order or ruling is issued under or pursuant to any statute of Canada or the United States or of any province or territory of Canada, or state of the United States (including, without limitation, the Commission, the Canadian Commissions, the TSX, NYSE American or the SEC) (other than any such inquiry, action, suit, investigation or other proceeding or order relating solely to the Underwriters), which in the reasonable opinion of the Underwriters (or any one of them) would be expected to operate to prevent or materially restrict trading in or distribution of the Offered Shares or would have a significant adverse effect on the market price or value of the Offered Shares; or

(d) the Company is in breach of any term, condition or covenant of this Agreement or any representation or warranty given by the Company in this Agreement becomes false in any material respect.

(2) If this Agreement is terminated by any of the Underwriters pursuant to Section 14(1), there shall be no further liability on the part of any terminating Underwriter or of the Company to such terminating Underwriter, except in respect of any liability which may have arisen or may thereafter arise under Section 10, Section 11 and Section 16. A notice of termination given by an Underwriter under this Section 14 shall not apply to or be binding upon any other Underwriter.

(3) The right of the Underwriters (or any one of them) to terminate their obligations under this Agreement are in addition to such other remedies as they may have in respect of any default, act or failure to act of the Company in respect of any of the matters contemplated by this Agreement.

SCHEDULE “B”

FORM OF OPINION TO BE PROVIDED BY COMPANY’S U.S. COUNSEL

1. Neither the execution and delivery by the Company of the Underwriting Agreement nor the consummation by the Company of the issuance and sale of the Offered Shares contemplated thereby will violate any federal U.S. Securities Laws.

2. No consent, approval, authorization or order of, or filing, registration or qualification with, any Governmental Authority, which has not been obtained, taken or made (other than as required by any state securities laws, as to which we express no opinion) is required on the part of the Company under any Applicable Law for the issuance or sale of the Offered Shares or the performance by the Company of its obligations under the Underwriting Agreement. For purposes of this opinion, the term “Governmental Authority” means any executive, legislative, judicial, administrative or regulatory body of the State of New York or the United States of America. For purposes of this opinion, the term “Applicable Law” means those laws, rules and regulations of the United States of America and the State of New York, in each case which in our experience are normally applicable to the transactions of the type contemplated by the Underwriting Agreement.

3. The Company is not currently, and solely after giving effect to the offering and sale of the Offered Shares and the application of the proceeds thereof as described in the U.S. Final Prospectus will not be, required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

4. To our knowledge, no person has the right to require registration of any common shares or any other securities of the Company under the Securities Act resulting from the filing or effectiveness of the Registration Statement, the U.S. Prospectus or otherwise.

5. The statements in the U.S. Prospectus under the heading “Certain U.S. Federal Income Tax Considerations” with respect to the tax considerations under United States federal income tax law, to the extent that they constitute summaries of United States federal statutes, rules and regulations, or portions thereof, are accurate in all material respects.

6. Pursuant to Rule 467(a) under the Securities Act, the Registration Statement became effective upon the filing of the Amendment No. 2 to the Registration Statement with the SEC on [●], 2024. To our knowledge, based solely upon our review of the SEC’s website, no stop order suspending the effectiveness of the Registration Statement has been issued. According to the SEC’s EDGAR database, the Form F-X was filed with the SEC prior to the effectiveness of the Registration Statement.

7. Assuming the compliance of the Canadian Final Prospectus, including the documents incorporated by reference therein, with the requirements of the securities laws and regulations of the Province of British Columbia and other requirements of Canadian law, the Registration Statement and the U.S. Final Prospectus (other than the financial statements, including schedules, and other financial and statistical information contained therein or omitted therefrom, as to which we express no opinion) appear on their face to be

B - 1 Underwriting Agreement

appropriately responsive as to form in all material respects with the applicable requirements of the Securities Act and the rules and regulations thereunder.

8. The Form F-X, as of its date, appeared on its face to be appropriately responsive in all material respects to the requirements of the Securities Act and the rules and regulations thereunder applicable to such form.

Such counsel shall also state in a separate letter as follows:

We have participated in the preparation of the Registration Statement, the U.S. Final Prospectus, and the Time of Sale Prospectus and in conferences and telephone conversations with officers and other representatives of the Company, including its Canadian counsel, representatives of the Underwriters, including their United States and Canadian counsel, and the independent auditors for the Company, during which the contents of the Registration Statement, the U.S. Final Prospectus and the Time of Sale Prospectus and related matters were discussed and, although the limitations inherent in the independent verification of factual matters and the role of outside counsel are such that we have not undertaken to verify independently, and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement or the U.S. Final Prospectus or Time of Sale Prospectus, except as set forth in paragraph 5 above, on the basis of the foregoing (and relying as to factual matters on officers, employees and other representatives of the Company), in the course of our work in connection with the matters contemplated by the Underwriting Agreement, no information has come to our attention that leads us to believe that (a) the Registration Statement, at its effective date and on the date hereof (except for the financial statements, financial statement schedules and other financial or accounting data included or incorporated by reference therein or omitted therefrom or from those documents incorporated by reference in each case, and the information derived from the reports of, or prepared under the supervision of or reviewed by (as stated therein), qualified persons employed or formerly employed by the Company, in reliance on the authority of such persons as “experts” within the meaning of the Securities Act, as to which we express no such belief), contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (b) the U.S. Final Prospectus, as of its date and as at the date hereof (except for the financial statements, financial statement schedules and other financial or accounting data included or incorporated by reference therein or omitted therefrom or from those documents incorporated by reference in each case, and the information derived from the reports of, or prepared under the supervision of or reviewed by (as stated therein), qualified persons employed or formerly employed by the Company, in reliance on the authority of such persons as “experts” within the meaning of the Securities Act, as to which we express no such belief), included or includes an untrue statement of a material fact or omitted or omits 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 or (c) the Time of Sale Prospectus at the Applicable Time (except for the financial statements, financial statement schedules and other financial or accounting data included or incorporated by reference therein or omitted therefrom or from those documents incorporated by reference in each case, and the information derived from the reports of, or prepared under the supervision of or reviewed by (as stated therein), qualified persons employed or formerly employed by the Company, in reliance on the authority of such persons as “experts” within the meaning of the Act, as to which we express no such belief), included or includes an untrue statement of material fact or omitted or omits to state a material fact

The foregoing paragraph shall not apply to (A) dispositions to any trust for the direct or indirect benefit of the undersigned and/or the spouse, any lineal descendent, father, mother, brother or sister of the undersigned, provided that such trust agrees in writing with Eight Capital to be bound by the terms of this Lock-Up Agreement, (B) tenders pursuant to a bona fide third party take-over bid made to all holders of Common Shares of the Company or similar acquisition transaction provided that in the event that the take-over bid or acquisition transaction is not completed, any Locked-Up Securities shall remain subject to the restrictions contained in this Lock-Up Agreement, (C) any dispositions pursuant to any pre-existing 10b5-1 plans, (D) exercise of stock options and related dispositions of shares under any stock options issued or outstanding under the Company’s equity incentive compensation plans, (E) any dispositions required for tax withholdings in connection with the exercise or vesting of any stock options or restricted stock units issued or outstanding under the Company’s equity incentive compensation plans, (F) by testate succession or intestate succession, (G) by operation of law, such as pursuant to a qualified domestic order or in connection with a divorce settlement, or (H) if acquired by the undersigned in open market transactions after the Offering.

In addition, the undersigned hereby waives any and all pre-emptive rights, participation rights, resale rights, rights of first refusal and similar rights that the undersigned may have in connection with the Offering or with any issuance or sale by the Company of any equity or other securities in connection with the Offering.

The undersigned hereby confirms that the undersigned has not, directly or indirectly, taken, and hereby covenants that the undersigned will not, directly or indirectly, take, any action designed, or which has constituted or will constitute or might reasonably be expected to cause or result in the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Common Shares.

The undersigned understands that the Company and the Underwriters are relying upon this Lock-Up Agreement in proceeding toward the consummation of the Offering. The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s legal representatives, successors, and assigns, and shall enure to the benefit of the Company, the Underwriters and their legal representatives, successors and assigns.
