(b) In addition to its right to designate the First Mitsui Nominee pursuant to Section 2(a), for so long as Mitsui meets the 20% Threshold, Mitsui shall be entitled, at its own discretion, to designate one additional nominee for election or appointment (as applicable) to the Board (the “Second Mitsui Nominee” together with the First Mitsui Nominee collectively the “Mitsui Nominees” and individually a “Mitsui Nominee”).

(e) NMG shall notify Mitsui of its intention to hold an annual meeting of Shareholders (or a special meeting at which the Shareholders are to vote for the election of Directors) at least 45 days and no more than 75 days before its Management Proxy Circular relating to such meeting is anticipated to be approved by the Board, subject to a shorter notification period with the prior written consent of Mitsui. Mitsui shall have the right to notify NMG of the Mitsui Nominee(s) designated by it in accordance with this Section 2 at any time, but at least 15 days before the said approval, failing which Mitsui shall be deemed to have designated the same Mitsui Nominee(s) who serves as a Director at such time, subject to such individual satisfying the conditions for appointment to the Board in Section 2(c).

(f) Before the first annual meeting of Shareholders following the date of this Agreement, or if the individual designated by Mitsui as a Mitsui Nominee ceases to be a director of NMG or if the Board position held by a Mitsui Nominee otherwise becomes vacant, Mitsui shall be entitled to recommend another individual as Mitsui Nominee to replace such Mitsui Nominee, and such individual shall be appointed by the Board as soon as reasonably possible, insofar as the Canada Business Corporations Act, applicable Canadian Securities Legislation and Exchange Rules allow, for a term ending at the close of the next annual meeting of Shareholders. Failing such a recommendation by Mitsui, the Board may fill the vacancy, but only if it is required to do so to comply with the Canada Business Corporations Act, applicable Canadian Securities Legislation and Exchange Rules, provided such director thereby designated by the Board resigns as soon as Mitsui decides to put forward a Mitsui Nominee to fill such vacancy.

(iv) the Management Nominees (other than: (i) in connection with any merger, amalgamation, arrangement, take-over bid, going private transaction or other similar transaction; or (ii) any Management Nominees that the Board is recommending as required under or in connection with arrangements with another Shareholder); and

(j) NMG shall, subject to the exclusions outlined in Section 2(k), give the Mitsui Observer(s) copies of all notices, minutes, consents, and other materials that it provides to its Directors at the same time and in the same manner as provided to such Directors; provided, however, that the Mitsui Observer(s) shall agree to enter into observer governance and confidentiality agreements with NMG, in form and substance satisfactory to NMG, acting reasonably (each, an “Observer Agreement”) prior to being permitted to attend any meetings of the Board and/or being provided with any materials provided to the Board (or any committee thereof).

(k) The Mitsui Observer(s) may be excluded from access to any material or meeting or portion thereof if such exclusion is reasonably necessary to preserve the attorney-client privilege, to prevent a conflict of interest between Mitsui and NMG, (it being understood that this includes any sensitive information relating to or potentially affecting NMG’s relationship with Mitsui or customers introduced by Mitsui and the agreements related thereto), to avoid antitrust issues, or as otherwise required in order to comply with any applicable Laws.

(l) For so long as a Mitsui Nominee is serving on the Board, such Mitsui Nominee shall be entitled in such Mitsui Nominee’s discretion to be a member of such committees of the Board to which such Mitsui Nominee may be appointed from time to time.

The price of the securities to be acquired by Mitsui under the Top-Up Right will be the closing price of the Common Shares on the TSX Venture Exchange (or, to the extent not listed on the TSX Venture Exchange, any recognized exchange on which the Common Shares are listed at the time) the day prior to the date of receipt of the Cure Notice. NMG shall use commercially reasonable efforts to obtain, and, subject to compliance with applicable Laws and stock exchange rules (including any hold period imposed by Applicable Securities Laws or any stock exchange), issue to Mitsui against payment of the subscription price payable in respect thereof, that number of securities set forth in the notice.

(i) Notwithstanding Section 3(c), in the case of a Cure Notice delivered in connection with a Subsequent Offering for which Mitsui did not send the Exercise Notice within the Exercise Notice Period, Mitsui shall have the right, subject to the receipt of all required regulatory and other approvals (including the approvals of each stock exchange on which the securities or the underlying securities of any convertible title are listed), within an additional 20 days after the closing of a Subsequent Offering, to give to NMG the Exercise Notice to subscribe and acquire securities, by way of a private placement, at the same price and conditions of the Subsequent Offering subject to any hold period imposed by Applicable Securities Laws and the rules of any stock exchange. NMG shall use commercially reasonable efforts to obtain, and subject to compliance with applicable Laws and stock exchange rules, issue to Mitsui against payment of the subscription price payable in respect thereof, the number of Common Shares or Convertible Securities, as applicable, set forth in the Exercise Notice.

(j) For greater certainty, if Mitsui does not decide to exercise its Top-Up Right within the 90-day period provided for in a Cure Notice, Mitsui will no longer be entitled to any Top-Up Right or other right in connection with the issuance referred to in the applicable Cure Notice (it being understood, for greater certainty, that if any other right referred to in this Section 3(j) requires a lower Mitsui Pro Rata Interest than the one for which the applicable Cure Notice was delivered, Mitsui shall be entitled to Top-Up Rights with respect to such rights requiring a lower Mitsui Pro Rata Interest in the event the Mitsui Pro Rata Interest becomes less than the applicable percentage as a result of any Dilution Event).

(k) Notwithstanding anything to the contrary in this Agreement, prior to the earlier of: (i) the FID Equity Financing and (ii) the date that is 180 days following the date of this Agreement, NMG shall not authorize, issue or sell any Common Shares or Convertible Securities in any jurisdiction or agree to do so or publicly announce any intention to do so pursuant to a debt or equity financing (public offering or a private placement) without the prior written consent of Mitsui, which consent may be withheld in Mitsui’s sole and absolute discretion.

(l) Mitsui shall not be entitled to exercise the Pre-Emptive Right and Top-Up Right under this Section 3, and all of the Mitsui’s rights under this Section 3 shall terminate on the date on which Mitsui ceases to meet the 10% Threshold.

(2) for the year ended December 31, 2023 and subsequent quarterly and annual reporting periods, as promptly as practicable following the end of each fiscal quarter and fiscal year, an unaudited reconciliation of NMG’s quarterly publicly issued financial statements with respect to such fiscal quarter and audited reconciliation of NMG’s annually publicly issued financial statements with respect to such fiscal year to IFRS, if it was reasonably determined by Mitsui, that this information is necessary for Mitsui’s financial reporting, accounting or tax purposes; and

(3) as promptly as practicable, such information and documentation relating to NMG and its Affiliates as Mitsui may reasonably request from NMG from time to time for purposes of complying with Mitsui’s tax reporting obligations with respect to its ownership of NMG.

At such quarterly strategic review meeting, which shall be chaired by a representative of NMG, the following topics with respect to NMG shall be addressed:

(1) quarterly review;

(2) growth strategy;

(3) operational issues;

(4) marketing issues;

(5) financing issues;

(6) collaboration between Mitsui and NMG;

(7) environmental, health and safety matters; and

(8) such other topics as may be suggested by either Party.

(b) The provision of any information pursuant to this Section 4 shall not be deemed a waiver of any privilege, including privileges arising under or related to the attorney-client privilege or any other applicable privilege.

(c) Subject to Section 4(d), upon receipt by NMG of a written notice from Mitsui advising NMG that: (i) Mitsui has determined that transacting in any Common Shares or Convertible Securities could reasonably be expected to trigger a violation of, or any liability to Mitsui under, Applicable Securities Laws; and (ii) Mitsui wishes to sell Common Shares or Convertible Securities beneficially owned by Mitsui, then, as soon as practicable, and no later than 9:00 a.m. (New York Time) on the seventh (7th) day following receipt by NMG of the written notice from Mitsui outlining the material non-public information relating to NMG or any of its subsidiaries known to Mitsui, NMG shall, through a press release or other public announcement (each, a “Cleansing Document”) in compliance with Regulation FD, make the Cleansing Announcement, including filing a copy of the Cleansing Document on SEDAR+.

(d) The obligation for NMG to make a Cleansing Announcement under Section 4(c) shall not apply:

(i) if the Board determines in good faith, after consultation with its financial and legal advisors, that the making of such Cleansing Announcement would: (A) have a material adverse effect on NMG; provided that the obligation of NMG to make a Cleansing Announcement in such case shall be deferred for a period of not more than ninety (90) days from the date of the receipt of the written notice from Mitsui in Section 4(c) (such 90-day period is referred to herein as a “Offtake Cleansing Blackout Period”); provided that after any initial Offtake Cleansing Blackout Period, NMG may not invoke a subsequent Offtake Cleansing Blackout Period until 12 months have elapsed from the end of any previous Offtake Cleansing Blackout Period; or (B) be prejudicial to NMG, provided that the obligation of NMG to make a Cleansing Announcement in such case shall be deferred for a period of not more than fourteen (14) days from the date of the receipt of the written notice from Mitsui in Section 4(c) (such 14-day period is referred to herein as a “Cleansing Blackout Period”); provided, that after any initial Cleansing Blackout Period, NMG may not invoke a subsequent Cleansing Blackout Period in respect of the same matter until 12 months have elapsed from the end of any previous Cleansing Blackout Period; or

(ii) during any periodic blackout period imposed by NMG pursuant to its disclosure policy for as long as a Mitsui Nominee is serving as a Director or Mitsui has elected to designate a Mitsui Observer.

13

5. Lock-Up

(a) Except as expressly permitted by Section 5(c), until the date that is 12 months following the date hereof (the “Lock-Up Expiration Date”), none of Mitsui or any of its Affiliates shall, directly or indirectly, assign, sell, transfer, offer, contract to sell, accept an offer to purchase, gift, pledge, encumber, hypothecate, provide a security interest in respect of, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, whether by actual disposition or effective economic disposition pursuant to any swap or other arrangement that transfers to another, in whole or in part, any interest in, or economic consequences of ownership of any of the Locked-Up Shares beneficially owned, directly or indirectly, by Mitsui (a “Transfer”).

(b) Following the Lock-Up Expiration Date and except as expressly permitted by Section 5(c), none of Mitsui or any of its Affiliates shall knowingly, Transfer any Locked-Up Shares to a Restricted Party or NMG Competitor, provided that any Transfer that takes place through the facilities of a stock exchange of which the Common Shares are listed or through a transaction facilitated by a broker dealer without disclosure being made to Mitsui of the purchaser of such securities, shall not constitute a breach of this Section 5(b).

(c) the restrictions and limitations in Section 5(a) and Section 5(b) shall not apply to:

(i) any Transfers, prior to the Lock-Up Expiration Date, to Japan SPC or any Affiliate of Mitsui, provided that any such transferee shall, prior to any such Transfer, agree to be bound by, and comply with, all of the obligations, covenants, provisions, and terms of this Agreement that are applicable to Mitsui, and shall deliver to NMG a duly executed undertaking to such effect in form and substance satisfactory to NMG, acting reasonably, or an agreement that NMG believes, acting reasonably, is substantively aligned with the terms of this Agreement, mutatis mutandis;

(ii) any Transfer pursuant to a bona fide third party “take-over bid” (as defined in National Instrument 62-104 Take-over Bids and Issuer Bids) provided that (1) such take-over bid is made to all shareholders of NMG, (2) in the event that the take-over bid is not completed in accordance with the terms recommended to shareholders by the Board, the Locked-Up Shares will remain subject to the restrictions and limitations contained in Section 5(a) and Section 5(b);

(iii) any Transfer pursuant to or in accordance with any “business combination” (as defined in Multilateral Instrument 61-101 Protection of Minority Security Holders in Special Transactions) involving NMG, provided that in the event that the business combination is not completed in accordance with the terms recommended to shareholders by the Board, the Locked-Up Shares will remain subject to the restrictions and limitations contained in Section 5(a) and Section 5(b);

(iv) any Transfer in connection with Mitsui pledging or hypothecating any Locked-Up Shares in favour of a Lender as security for a bona fide loan (a “Loan”), provided that, any such Transfer shall be on terms and conditions acceptable to the Board, acting reasonably, and without limitation, it will be deemed to be reasonable for the Board to require, as conditions of providing consent to any such Transfer, that (1) the Lender first agrees in writing with NMG to be bound by the terms of this Agreement, (2) NMG will have a contractual right with the Lender to cure any default or event of default by Mitsui under the Loan before the Lender will have any right to Transfer any Locked-Up Shares, and (3) upon the repayment of the Loan, the Locked-Up Shares will remain subject to the restrictions and limitations contained in Section 5(a) and Section 5(b); and

14

(v) any other Transfer of any securities pursuant to the exercise of any right pursuant to this Agreement, the Subscription Agreement, the Registration Rights Agreement or the Warrant Certificate.

6. Standstill

(a) Until 11:59 p.m. (Montréal time) on the date that is three years from the date hereof, Mitsui and its Affiliates will not, alone or in concert with others, without the prior written consent of NMG or as otherwise expressly permitted under this Agreement:

(i) purchase, acquire, or offer to purchase (except under the terms of the Subscription Agreement, the Registration Rights Agreement, the Warrant Certificate, or any other subscription agreement between Mitsui and NMG entered into following the date hereof) any equity securities of NMG (including Common Shares), except pursuant to:

(1) a stock dividend or dividend-in-kind paid by NMG or a subsidiary to all holders of Common Shares, including pursuant to any dividend reinvestment plan of NMG or a subsidiary;

(2) a security-based compensation arrangement;

(3) open market purchases of Common Shares following the FID Equity Financing, provided that, at any given time, the aggregate number of Common Shares purchased in all such transactions shall not be more than one percent (1%) of the number of issued and outstanding Common Shares at such time; or

(4) as otherwise permitted pursuant to Section 5(c);

(ii) effect, seek, offer or propose, or in any way advise or encourage any other Person to effect, seek, offer or propose (in each case, whether publicly or otherwise):

(1) any take-over bid, merger, amalgamation, plan of arrangement, reorganization or other business combination involving NMG or any of its assets; or

(2) any recapitalization, restructuring, liquidation, dissolution, disposition of a material portion of the assets or other extraordinary transaction with respect to NMG or any of its assets;

(iii) directly or indirectly make, or in any way participate in, any solicitation of proxies to vote, or seek to advise or influence any other Person with respect to the voting of any voting securities of NMG;

(iv) otherwise act in a manner to seek to control the management, Board or the policies of NMG beyond the Board and committee representation provided in this Agreement or as provided to the Japan SPC or its Affiliates;

(v) enter into any arrangements, understandings or agreements, whether written or oral, with, or advise, finance, aide, encourage or act in concert with, any other Persons (excluding Japan SPC and its Affiliates) in connection with any of the foregoing;

(vi) make any public announcement of any intention to do or take any of the foregoing or take any action that could require NMG to make a public announcement with respect to any of the foregoing; or

15

(vii) attempt to induce any party not to make or conclude any proposal with respect to NMG by threatening or indicating that Mitsui may take any of the foregoing actions.

(b) Mitsui will not, alone or in concert with others, without the prior written consent of NMG or as otherwise expressly permitted under this Agreement, purchase, acquire, or offer to purchase any equity securities of NMG that would result in Mitsui, Japan SPC, and their respective Affiliates owning, or exercising control over, more than 20% of the then outstanding Common Shares.

(c) Notwithstanding the foregoing, the limitations and prohibitions set forth in this Section 6 shall no longer apply from the earliest of:

(i) the date NMG enters into a definitive agreement with a third party that provides for (1) the acquisition by any means, including, without limitation, acquisition of equity, a statutory plan of arrangement, merger or business combination, by any Person, directly or indirectly, of more than 50% of the total voting power of the outstanding voting stock of NMG, (2) the date NMG enters into a definitive agreement with a third party that provides for an acquisition of all or substantially all of the assets of NMG, or (3)  the date a third party, alone or in concert with others, enters into a definitive agreement to acquire, or acquires, directly or indirectly, more than 50% of the voting securities of NMG; provided, however, that, in the event that the proposed transaction in (1), (2) or (3) is terminated, the limitations and prohibitions set forth in Section 6(a) shall be reinstated;

(ii) the date NMG makes a public announcement regarding the entering into of an agreement described in paragraph (i) above; and

(iii) the date the Board gives an opinion supportive of NMG entering into an agreement described in paragraph (i) above.

7. Agent/Distributor Right

(a) Subject to Section 7(b), for so long as Mitsui, Japan SPC and/or their respective affiliates hold, in the aggregate, all of the Common Shares purchased by Mitsui under the Subscription Agreement dated February 14, 2024, NMG hereby grants to Mitsui (or Mitsui’s affiliate(s) as designated by Mitsui) a right of first look for the sale and marketing of the active anode material produced at the Bécancour Project (the “Materials”) to all customers excluding Excluded Customers. If NMG is to sell Materials (other than to Excluded Customers), it shall provide notice to Mitsui in writing of its intent (the “First Look Notice”) and offer Mitsui the opportunity to engage in discussions to act as agent or distributor for such sales and marketing. Mitsui may also deliver to NMG a First Look Notice when and if, it desires to introduce a customer (other than an Excluded Customer) to NMG. The Parties shall discuss in good faith for 30 days following receipt of a First Look Notice the possibility of appointing Mitsui as agent or distributor, and, if agreed, the Parties shall discuss in good faith the details of and enter into an agent agreement or distributor agreement, as the case may be, for the respective sale and marketing activity, provided however that the commissions shall not be less than 3-4 % for the agency agreement and 5-8% for the distribution agreement for services, terms and conditions that are considered market standards by the Board for such remuneration. The First Look Notice shall describe the services to be rendered by Mitsui under either the agency agreement or the distribution agreement and the other terms and conditions. If following the expiry of the 30 day period, the Parties did not agree on the terms and conditions of an agency agreement or a distribution agreement, NMG may, subject to compliance with the right of first refusal provided for in accordance with Section 7(b) enter into discussions with a third party to solicit offers for an agency agreement or a distribution agreement. For greater certainty, in case the customer is an Asian Customer that is not an Excluded Customer, NMG shall, after having conducted the procedure set forth in this Section 7(a), comply with the procedure set forth in Section 7(b) before entering into any agency agreement or distribution agreement with any third party other than Mitsui (or Mitsui’s affiliate(s)).

16

(b) After the expiry of the 30 day period provided for in Section 7(a), if NMG receives a third party offer, NMG hereby grants to Mitsui (or Mitsui’s affiliate(s) as designated by Mitsui) a right of first refusal for any sale and marketing of the Materials to Asian Customers, in order to allow Mitsui to act as an agent of NMG or, where appropriate, a distributor of NMG, except in each case for the Excluded Customers set forth in subsection 7(c) below. NMG shall notify Mitsui in writing of the third party offer and Mitsui shall have a 20 day period to notify NMG that it elects to act as agent or distributor at the same terms and conditions of the third party offer; provided however that with respect to Asian Customers for which Mitsui has provided the scope and level of services NMG can reasonably expect be provided in connection with such relationship, the commission percentage shall, for the first five years following commencement of production at the Bécancour Project for services, terms and conditions that are considered market standards by the Board for such remuneration, be rephrased to the percentage of 3-4 % for the agency agreement and 5-8% for the distribution agreement, as the case may be, in such offer when presented to Mitsui by NMG regardless of the commission percentage stated in the said third party offer. The Parties agree to negotiate in good faith at the relevant time in order to set the applicable ranges of commissions for the agency and distribution agreements to be presented to Mitsui under this Section 7(b) that will apply after the fifth year following commencement of production at the Bécancour Project, it being understood that such percentages will reflect then current market rates. If, following the expiry of the 20-day period, Mitsui elects not to act as agent or distributor, NMG may enter into an agency agreement or a distribution agreement with the third party to sell the Materials.

(c) Mitsui acknowledges (i) the right of first look and (ii) the right of first refusal regarding customers headquartered in North America or Europe and joint venture(s) in which any of such customer(s) invests (who shall be the cell manufacturing operator of the joint venture regardless of such customer(s)’ shareholding percentage in the relevant joint venture) granted by NMG in favor of Pallinghurst. With respect to Mitsui’s rights of first look set forth in Section 7(a) and Pallinghurst’s right of first look, NMG shall allow both parties equal and fair opportunity to compete between them and shall choose either of them which provide more favorable proposal to NMG by taking into account of delivery terms, payment term, price, and so on, or appoint those parties co-agent or co-distributor as the case may be if both parties’ proposals are substantially the same and hard to determine which is more favorable to NMG. For the greater certainty, in case NMG appoints the said parties as co-agent or co-distributor, the commission referred to at Section 7(a) shall be allocated among Mitsui and Pallinghurst.

8. One CAD Put Right

(a) Mitsui is hereby granted the right to sell all of its then holding of shares in NMG to NMG at an aggregate sale price of a value of one Canadian dollar (Cdn$1.00) at any time at its sole discretion. Upon exercise of such right by Mitsui, NMG will immediately commence to use reasonable best efforts to materialize the sale.

9. Other Covenants of NMG

(a) For so long as Mitsui meets the 10% Threshold, NMG shall not, without Mitsui’s prior written consent:

(i) enter into any agreement in respect of, or otherwise support or recommend, a direct or indirect equity investment in NMG from, or any Change of Control to, a Sanctioned Person or a FEOC;

(ii) enter into any agreement in respect of, or otherwise support or recommend, any of the following transactions with a Restricted Party:

(1) a direct or indirect equity investment in an Affiliate of NMG that directly or indirectly owns the assets of NMG’s Matawinie mine project or the Bécancour battery material plant project (the “Subject Business”), including a joint venture with respect to the Subject Business;

17

(2) the acquisition by any means, including, without limitation, acquisition of equity, a statutory plan of arrangement, merger or business combination, directly or indirectly, of more than 50% of the total voting power of the outstanding voting stock of the Subject Business; or

(3) the acquisition, directly or indirectly, of the power to direct or cause the direction of the management or policies of the Subject Business;

except in any case where the failure to enter into any such agreement, or otherwise support or recommend any such transaction, would be inconsistent with the Directors’ fiduciary duties under applicable Laws.

(b) NMG shall maintain listing for its Common Shares on the TSXV and NYSE (the “Exchanges”), or another securities or stock exchange approved in advance by Mitsui, and shall not de-list or resolve to de-list its Common Shares from either Exchange without the prior written consent of Mitsui, which consent may be withheld in Mitsui’s sole and absolute discretion, unless such de-listing results from a merger, business combination or plan of arrangement in which the Shareholders receive securities of another listed entity or such de-listing results from the listing graduation from one of the Exchanges to another recognized securities or stock exchange, including, for the avoidance of doubt, any graduation from the TSXV to the TSX.

(c) For so long as Mitsui, Japan SPC, or any of their respective Affiliates is a shareholder of NMG, and in connection with NMG carrying out its related responsibilities:

(i) NMG shall cause its employees, Directors, officers, and to the best of its ability, any Person acting on its behalf to comply, with applicable Anti-Corruption Laws;

(ii) neither NMG, its subsidiaries, nor any of its or their employees, directors, officers, or to the knowledge of NMG, or any Person acting on its behalf shall:

(1) give, promise to give, or offer to give, any payment, loan, gift, donation, or anything else of value (including a facilitation payment) directly or indirectly, whether in cash or in kind, to or for the benefit of, any Government Official or any other Person while knowing or having reason to know that all or a portion of such money or thing of value will be offered, given, or promised, directly or indirectly, to any such Government Official or to any other Person for the purpose of: (A) improperly influencing any action or decision of any Government Official in their official capacity, including a decision to fail to perform official functions, (B) inducing any Government Official or other Person to act in violation of their lawful duty, (C) securing any improper advantage or (D) persuading any Government Official or other Person to use their influence with any Governmental Entity or any government-owned Person to effect or influence any act or decision of such Governmental Entity or government-owned Person; and

(2) accept, receive, agree to accept, or authorize the acceptance of any contribution, payment, gift, entertainment, money, anything of value, or other advantage in violation of applicable Anti-Corruption Laws; and

(iii) NMG shall (and shall cause its subsidiaries to) maintain policies and procedures reasonably designed to ensure compliance with all applicable Anti-Corruption Laws including records of payments to third parties (including, without limitation, agents, consultants, representatives, and distributors) and Government Officials. As soon as practicable after the date of this Agreement, and in any event within 30 days after the date on which NMG adopts an anti-corruption compliance policy, NMG shall provide a copy of such policy to Mitsui, together with the resolutions of the Board or other relevant official document evidencing NMG’s adoption of such policy. Upon reasonable request, NMG agrees to provide responsive information to Mitsui concerning its compliance with Anti-Corruption Laws. NMG shall promptly notify Mitsui if NMG becomes aware of any material violation of Anti-Corruption Laws.

18

(d) For so long as Mitsui, Japan SPC, or any of their respective Affiliates is a shareholder of NMG, and in connection with NMG carrying out its related responsibilities:

(i) NMG shall and shall cause its subsidiaries and its and their respective employees, directors, officers, and to the best of its ability, its and their respective agents, and any Person acting on its or their behalf to comply with all applicable Sanctions;

(ii) NMG shall, no later than January 1, 2026, institute and maintain a risk-based compliance program to ensure compliance with Sanctions by itself, its subsidiaries, and each of their respective directors, officers, and employees.

Within 30 days after the date on which NMG adopts such policy, NMG shall provide a copy of such policy to Mitsui, together with the resolutions of the Board or other relevant official document evidencing NMG’s adoption of such policy. Upon reasonable request, NMG agrees to provide responsive information to Mitsui concerning its compliance with Sanctions. NMG shall promptly notify Mitsui if NMG becomes aware of any material violation of Sanctions;

(iii) NMG shall not, and shall cause its subsidiaries and its and their respective employees, directors or officers not to, conduct any business transaction or activity with a Sanctioned Person or Sanctioned Territory; and

(iv) neither NMG, nor any of its subsidiaries or their respective directors, officers, or employees: (i) shall be a Sanctioned Person; or (ii) to the best knowledge of NMG, shall act under the direction of, on behalf of, or for the benefit of a Sanctioned Person.

19

(g) For so long as Mitsui, Japan SPC, or any of their respective Affiliates is a Shareholder, and in connection with NMG carrying out its related responsibilities:

(i) NMG shall cause its employees, Directors, officers, and to the best of its ability, any Person acting on its behalf to comply with all applicable Anti-Money Laundering Laws; and

(j) Notwithstanding the foregoing or anything to the contrary set forth in this Agreement, NMG and its subsidiaries agree to cooperate with any inquiry by Canadian Governmental Entities with respect to NMG’s business (or that of its subsidiaries) or any past or new investment NMG or its subsidiaries have received or undertaken, or receive or undertake, including by providing any information and documentary material lawfully required or requested by Canadian Governmental Entities, after due discussion with Canadian Governmental Entities.

Notwithstanding the foregoing:

(i) the Parties’ rights and obligations under Sections 2(p), 4(a)(iii), 8, 9(c), 9(d), 9(e), 9(f), 9(g), 9(i), 9(j), 9(k), 9(l), 9(m), 9(n) of this Agreement shall survive so long as Mitsui, Japan SPC or any of their respective Affiliates owns Common Shares;

(ii) the Parties’ rights and obligations under Section 4(a)(ii) (as it relates to clause (2) and (3) thereto) and Section 7 shall survive for the periods set forth therein; and

(iii) the termination of this Agreement shall not affect any of the rights or liabilities of any Party in connection with any breach of this Agreement which may have occurred before Mitsui ceases to hold any Common Shares or Warrant Shares in NMG.

(b) Termination of Side Letter. The side letter agreement between NMG and Mitsui dated October 19, 2022 (the “Side Letter”) is hereby terminated effective immediately. The parties hereto hereby waive any non-compliance with the terms of the Side Letter and any requirement for prior or further written notice of the transactions contemplated in the Subscription Agreement or this Agreement and the execution of this Agreement shall be conclusive proof of the receipt of any written notice each party hereto may request or require with respect to termination of the Side Letter.

(c) Amendment and Waiver. No amendment or waiver of any provision of this Agreement shall be binding on either Party unless consented to in writing by both Parties. No waiver by any Party of any provision hereof shall be effective unless explicitly set forth in writing and executed by the Party so waiving. No waiver of any provision (or any breach thereof) of this Agreement shall constitute a waiver of any other provision (or any breach thereof), nor shall any waiver of any provision of this Agreement constitute a continuing waiver unless otherwise expressly provided. No failure on the part of any Party to exercise, and no delay in exercising, any right under this Agreement shall operate as a waiver of such right. No single or partial exercise of any such right shall preclude any other or further exercise of such right or the exercise of any other right.

(d) Non-Assignment. Neither Party may assign any of its rights or benefits under this Agreement, or delegate any of its duties or obligations, except with the prior written consent of the other Party. Notwithstanding the foregoing, Mitsui may assign and transfer all of its rights, benefits, duties and obligations under this Agreement in their entirety, without the consent of NMG, to (i) an Affiliate of Mitsui or (ii) any Japan SPC, in each case provided that (1) any such assignee shall, prior to any such transfer, agree to be bound by, and comply with, all of the obligations, covenants, provisions, and terms of this Agreement that are applicable to Mitsui, and shall deliver to NMG a duly executed undertaking to such effect in form and substance satisfactory to NMG, acting reasonably, and (2) such assignment and transfer shall not release Mitsui from any accrued liability for its obligations under this Agreement.

(e) Expenses. Except as otherwise expressly provided in this Agreement, each Party shall pay for its own costs and expenses incurred in connection with the negotiation, preparation, execution and performance of this Agreement and the transactions contemplated herein, including the fees and expenses of legal counsel, financial advisors, accountants, consultants and other professional advisors.

(f) Further Acts. Each Party shall promptly do, make, execute, deliver, or cause to be done, made, executed or delivered, all such further acts, documents and things as the other Party may reasonably require from time to time for the purpose of giving effect to this Agreement.

(j) Governing Law.

(k) Resolution of Disputes.

(i) The parties shall discuss and use reasonable efforts to settle any Disputes (as defined below).

(ii) Any dispute, claim, difference, or controversy arising out of, relating to or having any connection with this Agreement, including any dispute as to its existence, validity, interpretation, performance, breach or termination, or the consequences of its nullity and any dispute relating to any non-contractual obligations arising out of or in connection with this Agreement (a “Dispute”), which cannot be settled pursuant to Section 10(k)(i) within 20 days from receiving written notice from either party of the existence of such Dispute, shall be referred to and finally resolved by arbitration under the Rules of Arbitration of the International Chamber of Commerce (the “ICC Rules”). All issues of arbitrability, including the existence, scope, or applicability of the agreement to arbitrate, are delegated to the arbitral tribunal constituted under the ICC Rules, or another authority in accordance with such ICC Rules.

(iii) The seat of the arbitration shall be New York. The parties may agree to hold hearings or other meetings in other locations.

(iv) The language of the arbitration shall be English. All documents submitted in connection with the proceedings shall be in the English language, or, if in another language, accompanied by an English translation.

(v) The parties agree that any arbitration shall be maintained confidential and that the existence of the proceeding and any element of it (including but not limited to any pleadings, briefs or other documents submitted or exchanged, any testimony or other oral submissions, and any awards) shall not be disclosed beyond the tribunal, the parties, their counsel and any person necessary to the conduct of the proceeding, except as may be lawfully required in judicial or regulatory proceedings. For the avoidance of doubt, no award or procedural order made in the arbitration shall be published.

(vi) The number of arbitrators shall be one. The single arbitrator shall be qualified by education and experience to determine the subject matter of the dispute. The parties shall endeavour to nominate the sole arbitrator by agreement. If the parties have not agreed upon a person to act as arbitrator hereunder within 30 days after any party’s request for arbitration, the arbitrator shall be chosen pursuant to the applicable ICC Rules.

(vii) The arbitrator shall be independent and impartial of each party. The parties agree to comply with the International Bar Association Guidelines on Conflicts of Interest in Arbitration in matters concerning prospective arbitrator appointments and disclosure of relationships between parties, party representatives, and the arbitrator.

23

(viii) The award shall be final and binding upon the parties. Unless otherwise provided by this Agreement, the arbitral award may involve any form of any relief permitted by New York law and deemed appropriate by the tribunal, including specific performance of the parties’ obligations. To the fullest extent permitted by any applicable law, each party hereby waives any right to appeal, challenge, annul, set aside or vacate the award on any grounds (including on the grounds that the award is against public policy, invalid or unenforceable) in any national courts. Each party undertakes to make any payments required by, or otherwise comply with, the award within a period of 30 days following the date of the award.

(ix) Each party shall bear its own fees and costs for any arbitration, provided that, the arbitrator finds that any party has caused undue delay in the arbitration or has otherwise acted unreasonably in initiating or causing such arbitration to be initiated or during the course of the arbitration, then the arbitrator may, in his or her sole discretion award fees and costs against such party.

(x) Each party hereby acknowledges that it would not have an adequate remedy at law for money damages in the event that this Agreement was not performed in accordance with its terms and therefore agrees that each party shall be entitled to specific performance and/or interim relief. The parties hereby acknowledge and agree that they may apply to the tribunal or to any court of competent jurisdiction for conservatory or interim measures. Nothing in this clause shall be construed as precluding a party from seeking a remedy at law in conjunction with specific performance and/or interim relief, even though the remedy at law it is inadequate.

(xi) Notwithstanding the initiation of dispute resolution procedures in accordance with this Section 10(k), the parties shall continue to perform their respective obligations under this Agreement.

Considering NMG being a listed company, NMG and Mitsui shall cooperate with each other in order to file, disclose, or complete such other procedure applicable under the relevant applicable Laws and/or stock exchange rules in order to give full effect to the terms and conditions set forth in this Agreement. If any of the terms and conditions are not permitted under the said Laws and/or rules, then NMG and Mitsui shall discuss in good faith the necessary adjustments to achieve the similar effect to the terms and conditions set forth herein to the extent possible.

(m) Confidentiality. The confidentiality obligations and restrictions of the parties contained in the framework agreement among NMG, Mitsui, and Panasonic Energy Co., Ltd dated October 20, 2022 shall apply to this Agreement as if fully set forth herein.

(n) Public Notices/Press Releases. No Party shall (i) issue any press release or otherwise make public announcements or disclosures with respect to this Agreement without the consent of the other Party (which consent shall not be unreasonably withheld or delayed), or (ii) make any regulatory filing with any Governmental Entity with respect thereto without prior consultation with the other Party; provided, however, that, this Section ‎10(n) shall be subject to each Party’s overriding obligation to make any disclosure or regulatory filing required under applicable laws and the Party making such requisite disclosure or regulatory filing shall use all commercially reasonable efforts to give prior oral and written notice to the other Party and reasonable opportunity to review and comment on the requisite disclosure or regulatory filing before it is made; provided, further, that, except as required by applicable Laws, in no circumstance shall any such disclosure by, or regulatory filing of, NMG or any of its Affiliates include the name of the Mitsui and/or its Affiliates without Mitsui’s prior written consent, in its sole discretion.

24

(o) Language. The Parties confirm their express wish that this Agreement and all related documents be drafted in the English language. Les Parties confirment leur volonté expresse que la présente convention et tous les documents s’y rattachant soient rédigés en langue anglaise.

(p) Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced under any applicable Laws or as a matter of public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Agreement be consummated as originally contemplated to the greatest extent possible.

(q) Entire Agreement. This Agreement, the provisions contained in this Agreement, and the agreements and other documents to be delivered pursuant to this Agreement, constitute the entire agreement between the Parties with respect to the subject matter thereof and supersede all prior communications, proposals, representations and agreements, whether oral or written, with respect to the subject matter thereof. Nothing in this Section 10(q) limits or excludes any liability for fraud.

(r) Counterparts. This Agreement and all documents contemplated by or delivered under or in connection with this Agreement may be executed and delivered (including by electronic means, e.g., DocuSign or Adobe Sign) and delivered via electronic mail (including pdf), or other transmission or method in any number of counterparts, with the same effect as if each Party had signed and delivered the same document, and all counterparts shall be construed together to be an original and shall constitute one and the same agreement.
