Sponsorship Agreement

Date	23rd September, 2021
Parties
	The Kingdom of Tonga (the “State”)/ The Tonga Seabed Minerals Authority, established under the Seabed Minerals Xxx 0000 (“the Act”) AND Tonga Offshore Mining Limited (“TOML”)
Recitals
A	TOML has the exclusive right to explore for Polymetallic Nodules in the International Seabed Area pursuant to the ISA Exploration Contract.
B	The State has Sponsored TOML’s Activities in the International Seabed Area pursuant to the Sponsorship Certificate, and agrees to maintain Sponsorship on the terms of this Agreement.
C	In exchange for the State’s sponsorship, TOML will pay a Commercial Recovery Payment during Exploitation in accordance with Section 91(2)(b) of the Act.
D	The Commercial Recovery Payment will be paid via the Tonga Seabed Minerals Authority to the Seabed Minerals Fund, in accordance with the Act to provide benefits to Tonga’s current and future generations in a transparent manner. In this way, the Commercial Recovery Payment paid by TOML during Exploitation is intended to provide significant benefits with a high social rate of return to the people of Tonga.
E	TOML currently provides capacity building initiatives for Tongan nationals and proposes to continue to provide such initiatives during the Exploration and Exploitation phases.
F	The exploration and exploitation will be carried out in the International Seabed Area, which is outside the sovereign jurisdiction of the State. For clarity, the State does not own the Polymetallic Nodules contained in TOML’s Tenement Area. Polymetallic nodule processing will also be carried out in a different national jurisdiction to the State given geographic and infrastructure constraints.

Sponsorship Agreement

G	The seafloor minerals contained in the Tenement Area are administered by the ISA, and TOML will be required to make payments to the ISA for the right to recover the minerals during Exploitation. In addition, because deep-sea mineral production involves many different areas of expertise and speciality, TOML will likely engage subcontractors for certain parts of the project. These subcontractors will need to earn a profit and will pay taxes in their own national jurisdictions.
H	It is acknowledged that considerable funds will be required to be expended at risk before any commercial development of the Polymetallic Nodules in the Tenement Area. The State is not making any monetary investment in the Exploration and Exploitation activities in the Tenement Area, and accordingly is not exposed to the risk of loss associated with such investment.
I	TOML undertakes that its Polymetallic Nodule Exploitation in the International Seabed Area will not directly impact on the environment in the Kingdom of Tonga and will not cause depletion of the Kingdom of Tonga’s own mineral resources.
J	With regard to the respective obligations and commitments under this Agreement, each of the parties covenant that it shall act in good faith and deal fairly with the other party.

For good and valuable consideration, the Parties hereto agree to be bound by the following terms and conditions:

1. Term

1.1 This Agreement will remain in force for the duration of TOML’s 15 year ISA Exploration Contract, and any extensions thereof, and will automatically extend for a further 25 years upon TOML being granted an ISA Exploitation Contract, unless:

(a) TOML’s ISA Contract is terminated by the ISA as a result of TOML breaching the ISA Contract; or

(b) this Agreement is terminated pursuant to clauses 10.6, 11, 21, or 22 of this Agreement.

1.2 During the Term TOML shall, within 30 days of the end of each calendar year, submit a report to the Tonga Seabed Minerals Authority, containing information on its program of Activities for the previous year. Within 60 days of submitting the report, the parties shall meet to discuss the report, as well as the performance of each of the parties under this Agreement, to ensure the Agreement is being fulfilled as originally intended.

Sponsorship Agreement

2. Sponsorship

2.1 The State agrees to:

(a) provide and maintain Sponsorship of TOML and TOML’s Exploration and Exploitation of the Tenement Area (including providing Sponsorship of TOML’s Exploitation application(s) to the ISA) for the Term of this Agreement; and

(b) do all things reasonably necessary to give effect to TOML having the full benefit of the Sponsorship, including renewing TOML’s Sponsorship Certificate, undertaking communications with, and providing documentation, certificates and undertakings to, the ISA or other regulatory body required in respect of the Sponsorship.

2.2 For clarity, the State acknowledges that the Sponsorship is provided by the State, as a signatory to UNCLOS, for the purposes of UNCLOS and the ISA Regulations and that neither this Agreement nor Sponsorship confers on the State any rights to or in connection with:

(i) the Tenements;

(ii) the Polymetallic Nodules contained within the Tenements or recovered therefrom; or

(iii) any product produced from the processing of the Polymetallic Nodules.

2.3 TOML will have the exclusive enjoyment and right to carry out the Exploration and Exploitation in the Tenement Area, and TOML may at its sole discretion deal with the title and ownership of Tenements and Polymetallic Nodules in any way.

2.4 The State recognizes that the Exploration and Exploitation within the Tenements shall require significant international financing, and the State agrees to use its best efforts to assist the TOML Group to obtain financing, including entering into agreements and providing formal documents that the lenders, investors and other third parties may reasonably require in relation to Sponsorship and the provision of regulatory certainty, however nothing herein will require or be deemed that the State has provided or guaranteed any such financing.

2.5 For the avoidance of doubt, the State is only sponsoring TOML, and is not sponsoring or responsible for the activities of any other entity in the TOML Group.

2.6 For clarity, the Sponsorship Certificate is also referred to as a Title under the Act.

23.09.2021 Page 4

Sponsorship Agreement

3. Commercial Recovery Payment

3.1 In exchange for the State agreeing to provide continued Sponsorship for the Term on the terms set out in this Agreement, TOML shall pay to the Tonga Seabed Minerals Authority during Payment Years a Commercial Recovery Payment (“CRP”) in accordance with this Clause 3.

3.2 The Commercial Recovery Payment will be US$[***] per Tonne of Polymetallic Nodules Recovered from the Tenement Area during Payment Years.

3.3 The CRP shall be paid in arrears on or before the last day of the month immediately following the end of each calendar quarter during Payment Years.

3.4 The CRP is fixed for the first five years of this Agreement, and shall be adjusted (on a compounding basis) on the first day of January in each following year by the relevant factor in each following year that represents official inflation in the United States of America using the All Items Consumer Price Index for All Urban Consumers (CPI-U) for the U.S. City Average published from time to time by the United States Department of Labour, Bureau of Labour Statistics. For example, if official inflation in the US is 3% in the 6^th year of this Agreement the CRP will be increased by 3% from US$[***] to US$[***].

3.5 Until such time as TOML reaches the Minimum Recovery Level within the Tenement Area, no CRP or other amounts or payments will be payable by TOML to the State, except for the Administration Fee under Section 18 of this Agreement.

3.6 Subject to Sections 9 and 18 of this Agreement:

(a) the State hereby agrees that the CRP contemplated under this Section 3 represents the totality of the monetary contributions, payments and Taxes the TOML Group is required to make to the State;

(b) the TOML Group will not be subject to or required to pay any other Taxes for the Term, including without limitation any Tax related to the Exploration, Exploitation, the TOML Rights, the Business and/or Sponsorship.

3.7 The State hereby undertakes and affirms that at no time will the rights (and the full and peaceful enjoyment thereof) granted by it under this Agreement be discriminately derogated from or otherwise prejudiced by any Tongan Law or the action or inaction of the State, or any official thereof, or any other person whose actions or inactions are subject to the control of the Government. To the extent there is inconsistency between any future Tongan Law related to taxation or the financial terms between the State and the TOML Group, then this Agreement will govern.

23.09.2021 Page 5

Sponsorship Agreement

3.8 In accordance with Section 94 of the Act, once the CRP has been received by the Tonga Seabed Minerals Authority, the Tonga Seabed Minerals Authority will pay the funds in to the Seabed Minerals Fund, excepting any funds allocated by the Treasury to be used directly for the purposes of covering the costs of establishing the Tonga Seabed Minerals Authority and performing the functions under the Act.

4. Audit

4.1 The State may, not more than once each calendar year, request in writing an independent audit of the amount of Polymetallic Nodules Recovered in the preceding calendar year (“Production Audit”). If the State requests a Production Audit, TOML and the State shall seek to agree on a suitably qualified and independent auditor to conduct the Production Audit.

4.2 TOML will provide the auditor with reasonable access to its records for the purpose of undertaking the Production Audit.

4.3 The Parties will require the auditor to provide a written report to the Parties on the findings of the Production Audit within 30 days of completion of the Production Audit. In the absence of manifest error, the findings of the auditor will be binding on the Parties.

4.4 If the auditor determines that a materially larger or smaller (i.e. more than 5%) amount of Polymetallic Nodules were Recovered from the Tenement Area in the preceding year than reflected in the CRP calculated by TOML for the year pursuant to clause 3, then within 30 days of receipt of the auditor’s report, TOML must recalculate in accordance with the accurate and revised figures determined by the auditor for that year the CRP under clause 3, and pay to (or deduct from future payments to) the State the difference between the CRP already paid and the CRP due under clause 3 on the basis of the revised figures.

4.5 The cost of an audit under this clause will be borne equally between the State and TOML.

5. Undertaking to Comply with ISA Contract Terms

5.1 TOML shall ensure that the Activities carried out in the International Seabed Area will be in compliance with:

(i) the terms and conditions of the applicable ISA Contract that is in existence at the time and that pertains to the Activities in the International Seabed Area, including the environmental terms and conditions contained in the applicable ISA Contract; and

(ii) TOML’s ISA Obligations that pertain to the Activities in the International Seabed Area.

5.2 TOML and its Subcontractors will not commit any actions, or make any omissions that would cause the State to materially breach its Sponsorship Obligations.

23.09.2021 Page 6

Sponsorship Agreement

5.3 The State will not commit any actions or make any omissions that would cause TOML to breach its obligations under clause 5.1.

6. Subcontractors

6.1 Subject to the provisions of this clause, the State acknowledges and agrees that TOML may delegate to and/or contract with Subcontractors to undertake all or part of the Exploration and Exploitation.

6.2 Notwithstanding any delegation or contract to a Subcontractor, TOML:

(a) remains bound by its obligations under this Agreement and the Act to carry out the Activities in accordance with TOML’s ISA Obligations, and will take reasonable and appropriate measures to ensure that the Subcontractors comply with TOML’s ISA Obligations;

(b) agrees that the Exploration and Exploitation shall be carried out in accordance with TOML’s ISA Obligations and the Act, whether the Exploration or Exploitation is being carried out by TOML or a Subcontractor; and

(c) is responsible to the State for any monetary damage the State suffers under UNCLOS for a breach of its Sponsorship Obligations resulting from the acts, negligence, omissions or defaults of any Subcontractor in carrying out the Activities in the International Seabed Area, as if they were the acts, negligence, omissions or defaults of TOML.

6.3 TOML shall take reasonable and appropriate measures to ensure that the Activities carried out in the International Seabed Area are executed by and under the supervision of appropriately qualified, experienced and skilled personnel.

7. Training and Capacity Building

TOML will implement training and capacity building initiatives for Tongan nationals.

8. Indemnification

8.1 Except to the extent that an award of damages is available as a consequence of a breach of this Agreement and subject to clause 8.3, TOML indemnifies and will keep indemnified the State from and against all costs, expenses, losses, charges, demands, actions, damages and Claims or other monetary liabilities under UNCLOS that the State suffers, incurs, sustains or becomes liable for under UNCLOS to the extent to which the costs, expenses, losses, charges, demands, actions, damages and Claims or other monetary liabilities arise as a consequence of the Activities in the International Seabed Area being carried out wrongfully and directly causing the State to breach its Sponsorship Obligations.

23.09.2021 Page 8

Sponsorship Agreement

8.5 Notwithstanding anything contained in this clause 8, TOML will only be liable for direct damages, and shall not be liable for any indirect or consequential damages, and shall not be liable for, and the indemnity in clause 8.1 will be proportionately reduced to the extent that, any costs, expenses, losses, charges, demands, actions, damages or Claims or any other liabilities that the State suffers, incurs, sustains or becomes liable for or may suffer, incur, sustain or become liable for, to the extent that they arise from:

(a) a negligent or reckless act of the State or at the State’s direction or on its behalf;

(b) a situation where the State fails to act in good faith or acts in a way that discriminates against TOML; or

(c) a Material State Breach.

10. Tongan Laws, Expropriation and Corporate Existence

10.1 The State agrees and warrants that:

(a) any Tongan Laws and regulations brought into effect after the Commencement Date will not interfere with or diminish TOML’s rights with respect to any Tenements, the Business or the rights arising under this Agreement and must not be a Discriminatory Change in Tongan Law, except to the extent the State has an obligation at International Law to enact such laws in order to fulfil the State’s Sponsorship Obligations;

23.09.2021 Page 9

Sponsorship Agreement

(b) to the extent that TOML or the TOML Group’s rights and obligations under this Agreement conflict with their rights and obligations under any discriminatory Tongan Law, this Agreement will take precedence, and TOML and the TOML Group will be relieved of any obligations under Tongan Law to the extent that their rights and obligations conflict with Tongan Law;

(c) the State will take such actions necessary to give effect to the exemptions from applicable law and tax law expressly provided in this Agreement. For clarity, TOML will not be subject to any taxation with respect to TOML’s activities that occur outside of the State, including the Exploration and Exploitation and the sale of minerals and/or ore recovered from the Tenement Area.

10.2 Prior to bringing in any laws or regulations that are required by International Law to fulfil the State’s Sponsorship Obligations the State will provide TOML with reasonable and meaningful consultation.

10.3 The State must also notify TOML from time to time as to any applicable Tongan Law that may be brought in to effect to fulfil the State’s Sponsorship Obligations and shall provide TOML sufficient time to ensure that it is able to comply with those laws or otherwise seek dispute resolution between the Parties with regards to the application of such Tongan Law. In the event any such change comes into force and materially impacts on the financial obligations of TOML, then the parties agree to negotiate in good faith appropriate amendments to the payments contemplated to the State under this Agreement in order to maintain the same level of financial burden on TOML as of the date of execution of this Agreement.

10.4 The State shall not impose, nor shall it permit or authorise any of its agencies or instrumentalities or any local or other authority of the State to impose any Taxes, impositions, rates or charges of any nature whatsoever on or in respect of the titles, property, or other assets, products, materials, or services used or produced by or through the Activities or by any or all of the TOML Group otherwise in the conduct of its business pursuant to the TOML Rights nor will the State take or permit to be taken by any such State authority any other discriminatory action which would deprive the TOML Group of full enjoyment of the rights granted and intended to be granted by the TOML Rights or otherwise under this Agreement.

10.5 In enacting and implementing Tongan Laws and regulations the State shall at all times accord TOML fair and equitable treatment, and will provide a stable and predictable legal framework and make decisions consistently and transparently and in accordance with the legitimate expectations of TOML and the TOML Group.

23.09.2021 Page 10

Sponsorship Agreement

10.6 In the event there occurs any change in Tongan Laws (including without limitation provisions relating to imposts, duties, fees, charges, penalties, and Tax related legislation) after the date of this Agreement, and if upon TOML’s representation it appears that on a reasonable interpretation and application of the law it would have the effect of divesting, decreasing, or in any way limiting, reducing or withholding any rights or benefits accruing to TOML or the TOML Group under this Agreement or under current legislation, then the Parties shall, in good faith, negotiate to modify this Agreement so as to restore the economic rights and benefits of the TOML Group to a level equivalent to or as close as possible to what they would have been if such change had not occurred. If the economic rights and benefits of the TOML Group are not restored then TOML may at its election terminate this agreement.

10.7 The State will permit all bona fide monetary conversions and transfers related to the TOML Rights or the Business (including currency conversions, transfers to, by or on behalf of TOML, or any member of the TOML Group) to be made freely and without delay into and out of the Kingdom of Tonga provided the procedural laws applicable to the transfer of funds out of jurisdiction applicable to all persons are be complied with.

10.8 The State acting in good faith shall not do or cause to be done or permit any act, thing or omission whether legislative, executive or administrative which discriminates adversely and unfairly against TOML, any member of the TOML Group, the TOML Rights or the Business if it results, upon its application, in a deprivation of the full enjoyment of the rights granted or intended to be granted under this Agreement.

10.9 The State warrants and defends TOML’s title to possession and peaceful enjoyment of the TOML Rights and all property of TOML and any member of the TOML Group against Expropriation, confiscation, condemnation, and wrongful possession and, to the extent possible, destruction, disruption or interference by the State or any other person controlled by or acting on behalf of the State.

10.10 The State acknowledges that the Exploration, Exploitation and commercialisation of the TOML Rights will require a significant level of expenditure and commercial risk by the TOML Group. The State assures, agrees with and warrants to TOML that the State has no intention as at the date of this Agreement to, and that the State will not (and will not attempt, take any action to, or institute any measures to), directly or indirectly, nationalise or Expropriate TOML, any member of the TOML Group and/or their property (including the TOML Rights, the Business and any other rights or assets of the TOML Group). The State further agrees that it will not, directly or indirectly, subject the TOML Group to a measure or measures having the same nature or effect equivalent to nationalization or Expropriation (or attempt, take any action to, or institute any such measure or measures).

23.09.2021 Page 11

Sponsorship Agreement

10.11 In the event of any inconsistency between the provisions contained within this Agreement, the Parties agree that an interpretation of this Agreement will be preferred which gives TOML and the TOML Group the benefit of this Agreement without nationalisation or expropriation.

10.12 Provided TOML is in material compliance with this Agreement and the Companies Act, the State will take all necessary actions for the Term to ensure that the corporate existence of TOML as a body corporate duly organized and validly existing and in good standing under the laws of the State is maintained, including ensuring that all such authorisations, approvals, consents and licences are issued as may be required to enable TOML to maintain its good standing, including ensuring that certificates evidencing annual renewal of registration of incorporation are issued in a timely manner in accordance with the Companies Act. Unless TOML is in material breach of this Agreement and/or the Companies Act, the State shall ensure that no action is taken (either by the government or by any government entity or instrumentality) to interfere with the continued corporate existence and registration of TOML and such other members of the TOML Group incorporated in the State.

10.13 The State guarantees the conversion and transfer overseas of TOML earnings and savings or earnings of expatriate personnel, their affiliates and subcontractors, resulting from the Activities.

10.14 With respect to earnings of TOML servants or agents, and expatriate personnel, whilst the State will not place unnecessary restriction of transfer of funds legitimately earned by TOML servants or agents, and expatriate personnel, such transfers will comply with the procedural laws applicable to transfer of funds out of jurisdiction applicable to all persons.

11. Assignment of TOML Rights

11.1 The State agrees that any or all members of the TOML Group may Assign the TOML Rights or any part thereof at any time, at their sole discretion, without reason and without prior consultation, upon providing notification to the State.

11.2 In the event that a member of the TOML Group notifies the State that an Assignment is to be made or is proposed to be made the State shall sign all documents, do all things and take all measures reasonably requested by the TOML Group to facilitate that Assignment, and will not act in any way to prevent or delay the Assignment.

23.09.2021 Page 12

Sponsorship Agreement

11.3 Upon the later of:

(a) an Assignment being completed in favour of an assignee; or

(b) a Sponsorship Certificate being signed by a new country pursuant to the ISA Regulations under which that country sponsors the assignee under the Assignment (or the assignees nominee) as the new holder of the TOML Rights, this Agreement will terminate effective immediately and:

(c) TOML will no longer have any obligations to pay an Administration Fee or CRP to the State except:

(i) to cover the calendar year’s Administration Fee during which the Agreement is terminated; and

(ii) to cover any CRP owing in respect of any seabed mineral production that has occurred up to the day before completion of an Assignment;

(d) No Party shall be liable to any other Party, whether arising under contract, tort, strict liability or otherwise, for any:

(i) loss of anticipated profits, loss of opportunity, loss of use, loss of production, loss of contracts; or

(ii) consequential or indirect loss or damage, of any nature arising at any time from any cause whatsoever; and

(c) The indemnity provided to the State under clause 8.1 shall continue in force until the date that the State no longer has any responsibilities or potential liabilities under UNCLOS that may arise as a consequence of the Activities being carried out wrongfully.

11.4 For avoidance of any doubt, and subject to Clause 9.1, the State will not impose any Tax (including without limitation capital gains tax, stamp duty, sales tax or transfer tax) on any sale or transfer of:

(d) the TOML Rights;

(e) any asset held by the TOML Group;

(f) any TOML Group entity; or

(g) any shares in the TOML Group.

11.5 This Section 11 survives termination or expiry of this Agreement.

23.09.2021 Page 13

Sponsorship Agreement

12. Notification to TOML

12.1 Should the State or the Tonga Seabed Minerals Authority receive material information, correspondence or notices from the ISA or other regulatory body relating to:

(a) TOML;

(b) TOML’s ISA Obligations;

(c) the State’s Sponsorship Obligations;

(d) any Subcontractor;

TOML reserves the right to require any ESPMP Officer before receiving such information to first sign a confidentiality agreement in person that strictly limits the approved purpose of disclosure to that of carrying out the ESPMP and reporting to the State.

15. ESPMP Officers

15.1 Notwithstanding anything contained in this Agreement:
