Definitions: • Beneficiary(ies): as defined in the Indemnity Policy. • Proceeding(s): investigations, administrative, arbitral and/or judicial proceedings. 1. General Guidelines about Indemnity Agreements: 1.1 Vale shall take all necessary measures to indemnify the Beneficiaries in the event they are unduly included on a delinquent taxpayer registry or have their personal assets frozen as a result of any Proceeding. If the expense has not yet been incurred by the Beneficiary, Vale may, at its sole discretion, rather than reimbursing the Beneficiary for the expense, pay directly to whom it may concern. 1.2 If the Beneficiary has any checking account electronically frozen as a result of any scenario of indemnification pursuant to the Indemnity Policy (“Electronic Freeze”) and, while this Electronic Freeze has not been lifted, Vale undertakes to (i) provide directly to the Beneficiary, within at least six (6) business days after communication of the Electronic Feeze, an amount equivalent to the amount frozen in the checking account to be indicated by the Beneficiary, or (ii) make the payments directly to whom they may concern. This amount shall be returned to Vale by the Beneficiary, in the same period, after the Electronic Freeze is lifted. If the Electronic Freeze is partially lifted, the Beneficiary shall return only the amount equal to the amount effectively lifted. 2. Procedures to Trigger the Indemnity Agreement: 2.1 The Beneficiary shall notify Vale immediately of any Proceeding or decision rendered in the context of a Proceeding of which they are aware, through a communication in writing sent to Vale’s Executive Vice-President Legal Affairs (“VP Legal Affairs”), attaching all documents and information that are available regarding the Proceeding in question. 2.2 Once notification of a Proceeding is received, Vale’s VP Legal Affairs shall be responsible for verifying if the Beneficiary’s act is subject to coverage pursuant to the Indemnity Policy and/or Agreement, including if it can be unmistakably classified as one of the Exclusions. In the event that the Beneficiary is the acting VP Legal Affairs himself, they shall send their claim to Vale’s Executive Committee who shall conduct the verification and classification. 2.3 Vale’s VP Legal Affairs may, in exceptional cases or in cases with some ambiguity, submit the claim for analysis and resolution: (i) of Vale’s Board of Directors, in cases in which the Beneficiary is a member of the Board of Directors, Chief Executive Officer, Executive Vice-President or member of an Advisory Committee of Vale’s Board of Directors or member of the Fiscal Council, subject to the procedures about conflicts of interests contained in Vale’s Conflict of Interest Management Policy; and (ii) of the Executive Committee, in cases in which the Beneficiary is a former General Counsel/ VP Legal Affairs. 2.4 In the event that (i) more than half of the members of the Board of Directors are party to the Proceeding, or (ii) there is a dissenting vote regarding the classification of the act as subject to indemnification from five (5) Board Members or 1/3 (one-third) of the Executive Committee, as the case may be; Vale shall submit the claim for analysis and decision of an independent third party who is impartial and has an unblemished reputation and robust legal experience, whose name shall be recommended by Vale’s VP Legal Affairs and approved, as the case may be, by the non-conflicted Board Members or by the Executive Committee. The decision of this independent third party shall bind the Parties, who, hereby, assume the irrevocable and irreversible commitment to comply with its terms. In addition, the deadline for formal communication of Vale set forth in item 2.7 below shall be equivalent to half of the legal or regulatory deadline for submission of a defense of the Beneficiary. - 10 of 11 - Indemnity Policy POL-0031-G Rev.: 01-28/07/2021 DCA 057/2021 PUBLIC 2.5 Decisions about claims made based on the Policy and/or the respective Indemnity Agreement must be well-founded and take into consideration the act or omission of the Beneficiary that gave rise to the Proceeding, as well as all information and elements available at the time of the decision. These decisions may be reviewed by Vale or by the independent third party, as applicable, at any time, especially if new elements or evidence arise that have the power to modify the result of the evaluation that was made. 2.6 If it is proven by final arbitral, judicial or administrative decision that the act or omission of the Beneficiary is not subject to indemnification under any of the Exclusions set forth in the Policy, the effects of Vale’s obligations related to the Proceeding shall cease immediately, and the Beneficiary shall be required to reimburse Vale for all amounts disbursed or incurred by Vale during the course of the Proceeding or to end the Proceeding, within 10 (ten) business days after notification by Vale to that effect. 2.7 Subject to the procedure described above, Vale may (i) subsidize the Beneficiary’s defense, appointing internal attorneys or through attorneys chosen and hired by Vale, provided that it formally communicates to the Beneficiary within a maximum period equivalent to half of the legal or regulatory deadline that is provided to submit its statement or defense, and the Beneficiary shall grant the necessary powers-of-attorney granting general authority to a lawyer, including powers to participate in hearings and enter into settlements, in a timely manner for the defense; (ii) immediately take applicable measures for the initial defense of the Beneficiary in the event of arrest; and (iii) take all measures that it understands applicable, at its sole discretion, including, as the case may be, taking out bank or security guarantees, in the event that the Beneficiary must answer for corporate debts with their own property, is unduly included on a delinquent taxpayer registry or has their personal assets frozen. 2.8 If Vale does not make a communication within the period referred to above, the Beneficiary, backed by the Indemnity Agreement and Policy, shall be authorized to hire attorneys to act in their defense, and Vale shall bear the respective costs, provided that they are reasonable and compatible with those practiced in the market, subject to the other terms and conditions established in the Policy, in the respective Indemnity Agreement, and in the general hiring rules adopted by Vale. 2.9 The Beneficiary, backed by the Indemnity Agreement and Policy, may submit a justified objection to the name of the lawyer chosen by Vale to conduct their defense and, in this case, the new lawyer shall be chosen, in common agreement of the parties, among the names proposed on a list of at least three names by Vale. 2.10 Vale’s approval of any payment, reimbursement or refund of funds with respect to a Proceeding, whether to a Beneficiary or to whom it may concern, including providing guarantees and accepting or incurring expenses or expenditures of any kind and any settlements related to the Proceedings, shall be subject to the rules and limits regarding amounts contained in Vale’s internal rules and policies on delegation with respect to this topic, and shall take into consideration the need or convenience of the expenditure for the defense in the Proceeding and the reasonableness of the amounts involved, among other factors that are deemed relevant for the analysis of the appropriateness of the expenditure based on the information that is available at that time. 2.11 Any execution of in-court or out-of-court settlements or terms of commitment by the Beneficiary or equivalents to said documents, whether to end and/or prevent Proceedings, as well as the performance of any act by the Beneficiary that means ackowledgement of the claim filed or a waiver of defense in the Proceeding, shall only be subject to indemnification if Vale provided written consent in advance regarding the terms of said settlement or commitment or the performance of said acts. 2.12 The Board of Directors must be informed within two business days of any request for indemnification involving members of Vale’s Board of Directors, the Executive Committee, an Advisory Committee to the Board of Directors or the Fiscal Council, as well as periodically receive reports about amounts spent by Vale on indemnifications backed in the Indemnity Agreements. 3.

The decision of this independent third party shall bind the Parties, who, hereby, assume the irrevocable and irreversible commitment to comply with its terms. 3.5 Decisions about claims made based on the Policy must be well-founded and take into consideration the act or omission of the Beneficiary that gave rise to the Proceeding, as well as all information and elements available at the time of the decision. These decisions may be reviewed by Vale or by the independent third party, as applicable, at any time, especially if new elements or evidence arise that have the power to modify the result of the evaluation that was made. 3.6 If it is proven by final arbitral, judicial or administrative decision that the act or omission of the Beneficiary is not subject to indemnification under any of the Exclusions set forth in the Policy, the effects of Vale’s obligations related to the Proceeding shall cease immediately, and the Beneficiary shall be required to reimburse Vale for all amounts disbursed or incurred by Vale during the course of the Proceeding or to end the Proceeding, within 10 (ten) business days after notification by Vale to that effect. 3.7 Subject to the procedure described in items 3.1 to 3.6 above, Vale may (i) subsidize the Beneficiary’s defense, appointing internal attorneys or through attorneys chosen and hired by Vale, provided that it formally communicates to the Beneficiary within a maximum period equivalent to half of the legal or regulatory deadline that is provided to submit its statement or defense, and the Beneficiary shall grant the necessary powers-of-attorney granting general authority to a lawyer, including powers to participate in hearings and enter into settlements, in a timely manner for the defense; (ii) immediately take applicable measures for the initial defense of the Beneficiary in the event of arrest; and (iii) take all measures that it understands applicable, at its sole discretion, including, as the case may be, taking out bank or security guarantees, in the event that the Beneficiary must answer for corporate debts with their own property, is induly included on a delinquent taxpayer registry or has their personal assets frozen. 3.8 Vale’s approval of any payment with respect to a Proceeding, whether to a Beneficiary or to whom it may concern, including providing guarantees and accepting or incurring expenses or expenditures of any kind and any settlements related to the Proceedings, shall be subject to the rules and limits regarding amounts contained in Vale’s internal rules and policies on delegation with respect to this topic, and shall take into consideration the need or convenience of the expenditure for the defense in the Proceeding and the reasonableness of the amounts involved, among other factors that are deemed relevant for the analysis of the appropriateness of the expenditure based on the information that is available at that time. 3.9 Any execution of in-court or out-of-court settlements or terms of commitment by the Beneficiary or equivalents to said documents, whether to end and/or prevent Proceedings, as well as the performance of any act by the Beneficiary that means ackowledgement of the claim filed or a waiver of defense in the Proceeding, shall only be backed by Vale if Vale provided written consent in advance regarding the terms of said settlement or commitment or the performance of said acts.
