EARN OUT

6.1 Earn Out. If a Liquidity Event occurs, CSN may convert the Pre-Money Equity Value – Subscription Bonus into Congonhas Minérios’s shares (“Liquidity Event Conversion”) pursuant to this ARTICLE VI. For the avoidance of doubt, the Liquidity Event shall be a one time event and shall not be counted twice.

6.2 Pre-Money Valuation. The ratio for conversion of the Pre-Money Equity Value – Subscription Bonus into Congonhas Minérios’s shares shall depend on Congonhas Minérios’ pre money equity value related to the Liquidity Event (“Pre-Money Valuation”). The Pre-Money Valuation shall be calculated in accordance with (i) the price per share agreed and issued for the Qualified Private Sale or the price per share set forth in the announcement of the beginning of the Qualified IPO (Anúncio de Início), as the case may be, and (ii) the total number of shares of Congonhas Minérios, excluding the shares to be issued by Congonhas Minérios for the Liquidity Event.

6.3 Maximum Equity Value. If the Pre-Money Valuation is equal, in Brazilian reais, [] or greater (“Maximum Equity Value”), the Pre-Money Valuation shall be deemed to be [] for the purpose of the Liquidity Event Conversion.

6.4 Capital Increase Prior to the Liquidity Event. In the event Congonhas Minérios’ capital stock has been increased before the occurrence of the Liquidity Event, the Minimum Equity Value and the Maximum Equity Value shall be increased by the same amount of the increased amount of Congonhas Minérios’ capital stock and, as a result, the new amounts calculated as set forth herein shall be considered as the Minimum Equity Value and the Maximum Equity Value.

6.5 Conversion Ratio. The number of shares in Congonhas Minérios that CSN shall be entitled to receive as a result of the Liquidity Event Conversion shall vary linearly so that JKTC Parties shareholding ratio in Congonhas Minérios shall be JKTC Parties’s top

shareholding position in case the Pre-Money Valuation of the Liquidity Event is the Minimum Equity Value (“JKTC Liquidity Event Top Shareholding Position”), and shall be JKTC Parties bottom shareholding position in case the Pre-Money Valuation of the Liquidity Event is the Maximum Equity Value (“JKTC Liquidity Event Bottom Shareholding Position”). JKTC Parties’ top shareholding position, bottom shareholding position and final shareholding position shall be calculated as follows:

JKTC Liquidity Event Top Shareholding Position = JKTC Top Shareholding Position Post Merger Sale of Shares

JKTC Liquidity Event Bottom Shareholding Position = JKTC Bottom Shareholding Position Post Merger Sale of Shares

8.7 Indemnification Procedure. Claims for indemnification under this Agreement shall be asserted and resolved as follows:

(i) If a Claim by a third party is made against a CSN Indemnified Party or a JKTC Indemnified Party (any such Person, an “Indemnified Party”), and if such Indemnified Party intends to seek indemnity with respect thereto under this ARTICLE VIII, such Indemnified Party shall promptly furnish written notice of such Claim (in reasonable detail and including the factual basis for such Claim and, to the extent known, the amount thereof) to the party against whom indemnity is sought (such party, in such capacity, the “Indemnifying Party”). Thereafter, the Indemnified Party shall deliver to the Indemnifying Party, promptly after the Indemnified Party's receipt thereof, copies of all material notices and documents (including court papers) received or transmitted by the Indemnified Party relating to such Claim. The failure or delay of the Indemnified Party to deliver prompt written notice of a Claim shall not affect the indemnity obligations of the Indemnifying Party hereunder, except and only to the extent that, as a result of such failure, any Indemnifying Party that was entitled to receive such notice was deprived of its right to recover any payment under its applicable insurance coverage or was otherwise materially prejudiced as a result of such failure. The Indemnifying Party shall have five (5) Business Days after receipt of such notice to elect to undertake, conduct and control (through counsel of its own choosing and at its own expense, so long such counsel is approved by the other party, such approval not to be unreasonably delayed or withheld), and, in any event, shall have the right to participate (at its own expense) in, the settlement or defense of such Claim, and the Indemnified Party shall cooperate with it in connection therewith. If the Indemnifying Party elects to undertake, conduct and control the settlement or defense of such Claim, the Indemnifying Party shall permit the Indemnified Party to participate in such settlement or defense directly or through counsel chosen by such Indemnified Party (but the fees and expenses of such counsel shall be borne by such Indemnified Party). So long as the Indemnifying Party (at the Indemnifying Party's cost and expense) (i) has undertaken the defense of, and assumed full responsibility for all indemnified liabilities with respect to, such Claim, (ii) is reasonably contesting such Claim in good faith through appropriate proceedings and (iii) has taken such action (including the posting of a bond, deposit or other security) as may be necessary to prevent any action to foreclose a Lien against or attachment of the property and/or assets of the Indemnified Party or of Congonhas Minérios and its Subsidiaries, as the case may be, for payment of such Claim, the Indemnified Party shall not pay or settle any such Claim; provided, however, that, the Indemnified Party shall have the right to pay or settle any such Claim if it has waived in writing any right to indemnity by the Indemnifying Party for such Claim; and provided, further, that, if within five (5) Business Days after the receipt of the Indemnified Party's notice of a Claim of indemnity under this Section 8.7, the Indemnifying Party does not notify the Indemnified Party that it elects (at the Indemnifying Party's cost and expense) to undertake the defense thereof and assume full responsibility for all indemnified liabilities with respect thereto, or gives such notice and thereafter fails to contest such Claim in good faith or to prevent action to foreclose a Lien against or attachment of the Indemnified Party's property as contemplated above, the Indemnified Party shall have the right to contest, settle or compromise such Claim (at the Indemnifying Party’s costs and expenses) and the Indemnified Party shall not thereby waive any right to indemnity for such Claim under this Agreement. No Indemnifying Party shall consent to any settlement, compromise or discharge (including the consent to entry of any Judgment) of any such Claim without the Indemnified Party's prior written consent (which consent shall not be unreasonably withheld, delayed or conditioned); provided that, if the Indemnifying Party assumes the defense of any such Claim, the Indemnified Party shall agree to any settlement, compromise or discharge of such Claim which the Indemnifying Party may recommend and which by its terms obligates the Indemnifying Party to pay the full amount of Losses in connection with such Claim and definitely and unconditionally releases the Indemnified Party completely from all liability in connection with such Claim; provided, however, that the Indemnified Party may refuse to agree to any such settlement, compromise or discharge (a) that provides for injunctive or other nonmonetary relief affecting the Indemnified Party or (b) that, in the reasonable opinion of the Indemnified Party, would otherwise materially adversely affect the Indemnified Party. Whether or not the Indemnifying Party shall have assumed the defense of such Claim, the Indemnified Party shall not admit any liability with respect to, or settle, compromise or discharge (including the consent to entry of any Judgment with respect to), any such Claim without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld, delayed or conditioned) unless the Indemnified Party has waived in writing any right to indemnity from the

(ii) Any Claim on account of Losses for which indemnification is provided under this Agreement which does not involve a Claim of a third party shall be asserted by prompt written notice (setting forth in reasonable detail the facts or circumstances that allegedly gave rise to such Claim and, to the extent known, the amount thereof) given by the Indemnified Party to the Indemnifying Party from whom such indemnification is sought. The failure or delay of the Indemnified Party to deliver prompt written notice of a Claim shall not affect the indemnity obligations of the Indemnifying Party hereunder, except and only to the extent that, as a result of such failure, any Indemnifying Party that was entitled to receive such notice was deprived of its right to recover any payment under its applicable insurance coverage or was otherwise materially prejudiced as a result of such failure.

(iii) In the event of payment in full by an Indemnifying Party to any Indemnified Party in connection with any Claim (an “Indemnified Claim”), such Indemnifying Party shall be subrogated to and shall stand in the place of such Indemnified Party as to any events or circumstances in respect of which such Indemnified Party may have any right or Claim relating to such Indemnified Claim against any claimant or plaintiff asserting such Indemnified Claim or against any other Person. Such Indemnified Party shall cooperate with such Indemnifying Party in a reasonable manner and (at such Indemnifying Party's cost and expense) in prosecuting any subrogated right or Claim.

8.8 Survival and Time Limitation. Except as otherwise set forth herein, the terms and provisions of this Agreement, including the representations and warranties, shall survive the consummation of the Spin-off, the Merger and the Merger Sale of Shares contemplated in this Agreement. Any Claim by any JKTC Indemnified Party that CSN is liable to such JKTC Indemnified Party under the terms of this Agreement shall be brought against CSN until the 6^th anniversary of the Date of the Merger, provided that such time limitation shall not apply to Section 8.1(iii) and to Section 8.3. Notwithstanding the foregoing, an indemnification Claim brought pursuant to this ARTICLE VIII before the expiry of such deadlines will not be precluded hereby if the Claim is initiated in writing prior to the expiration of the applicable survival period described in the preceding sentence.

8.9 Further Indemnity Limitations. The amount of any Loss to be indemnified pursuant to this Agreement shall be reduced (i) to the extent any Indemnified Party actually receives any insurance proceeds with respect to such Loss, and (ii) to take into account any payment actually received by an Indemnified Party with respect to such Loss.

8.10 The Investors hereby agree that the conduction of the Due Diligence shall not, in any way, exempt or affect CSN’s indemnification obligation under Section 8.1(i).

If one or more arbitrations are already pending with respect to a Dispute under any such agreement, then any party to a new dispute or any subsequently filed arbitration brought under any such agreement may request that such new dispute or any subsequently filed arbitration be consolidated into any prior pending arbitration.

9.2.8 The new dispute or subsequently filed arbitration shall be so consolidated, provided that the ICC Court determines that: (i) the new dispute or subsequently filed arbitration presents significant issues of law or fact common with those in the prior pending arbitration; (ii) no party to the new dispute or prior pending arbitration would be prejudiced; and (iii) the consolidation under these circumstances would not result in undue delay for the prior pending arbitration.

9.2.9 The consolidation order shall be final and binding upon all the parties involved in the consolidated proceedings.

§8. The new dispute or subsequently filed arbitration shall be so consolidated, provided that the ICC Court determines that: (i) the new dispute or subsequently filed arbitration presents significant issues of law or fact common with those in the prior pending arbitration; (ii) no party to the new dispute or prior pending arbitration would be prejudiced; and (iii) consolidation under these circumstances would not result in undue delay for the prior pending arbitration.

6.4.1 Any Shareholder or Director, as applicable, may be represented at Prior Meetings by another Shareholder or Director appointed in writing. Shareholders or Directors may participate in Prior Meetings by conference call, video conference or any other means of communication that ensures the genuineness of the vote or opinion of Shareholders or Directors, as applicable, provided that a copy of the minutes of the meeting be approved by such Shareholder or Director, as applicable, and sent via email to the Chairman of the Board of Directors on the same date of the meeting, and the respective original be subsequently signed by all the Shareholders or Directors, as applicable, that attended such meeting.

(1) if the Company is a closely-held corporation, the JKTC Parties may, at their sole discretion, but no later than [*] from the date (a) the Relevant Transaction is formally presented to the JKTC Parties by CSN upon written notice, or (b) the Relevant Transaction is approved in a Shareholdersâ€™ meeting or Board of Directorsâ€™ meeting of the Company, as applicable, whichever occurs first, serve a notice to the Company and CSN (â€œRedemption Noticeâ€) requesting the redemption of all, but not less than all, of the Companyâ€™s shares held by the JKTC Parties, at their Fair Market Value (calculated without giving effect to the Relevant Transaction that triggered such right), subject to the consummation of the Relevant Transaction (â€œRedemption Rightâ€). The JKTC Parties shall not have the Redemption Right in case they (or the Director appointed by them) have voted in favor of the Relevant Transaction at the relevant Shareholdersâ€™ or Board

TEXT_SP 9294504v1 7474/36 56

of Directorsâ€™ meeting. Upon receipt of the Redemption Notice, the Shareholders irrevocably and irreversibly agree to approve, by unanimity, within not more than [] following the receipt of the Redemption Notice, in a Shareholdersâ€™ meeting (and only if the Relevant Transaction had been implemented or is implemented on the same meeting), the redemption of the Companyâ€™s shares held by the JKTC Parties at their Fair Market Value and payment of the redeemed shares within at least [] from the Shareholdersâ€™ Meeting that approved the redemption, and all related measures for its implementation, provided that, if needed, the shares to be redeemed shall be converted into a different class of shares, with the same rights, and

(2) if the Company is a publicly-held corporation, this Agreement shall be automatically terminated on the date the Relevant Transaction is consummated.

6.6.1 For the avoidance of doubt, in case the JKTC Minimum Rights are preserved as a result of the Relevant Transaction, the JKTC Parties shall not be entitled to exercise the Redemption Right and shall adhere to the new shareholdersâ€™ arrangement which shall reflect the JKTC Minimum Rights.

6.6.2 For the purposes of determining the â€œFair Market Valueâ€, the following conditions and procedures shall apply: within ten (10) days following receipt of the Redemption Notice, each of the Shareholders shall select one investment bank of international standing, which shall make an independent valuation of the Fair Market Value of the Company in USD amounts. The Shareholders agree that they shall cause such independent valuations to be made up to thirty (30) days following the date of the exercise of the Redemption Right and shall submit such determination to the other Shareholder. If the valuations differ by an amount that is [] or less of the higher valuation, then the Fair Market Value shall be calculated by obtaining the arithmetic average of the independent valuations of the two (2) investment banks. If any investment bankâ€™s valuation exceeds that of the other by more than [] of the higher valuation, the two (2) investment banks shall select a third investment bank, which shall make its own independent valuation of the Company within forty (40) days following the date on which both initial valuations have been submitted to the Shareholders by the initial two (2) investment banks. In case the valuation prepared by the third investment bank falls within the valuations prepared by the two (2) initial investment banks (i.e., the third valuation is greater than the lowest of the two (2) previous valuations and lesser than the greatest of such two (2) previous valuations), then the valuation prepared by the third investment bank shall be considered the final Fair Market Value of the Company. In case the valuation prepared by the third investment bank does not fall within the valuations prepared by the two (2) initial investment banks, then the final Fair Market Value of the Company shall be the valuation performed by the initial two (2) investment banks which is closer to the valuation prepared by the third investment bank. The Shareholders shall each bear the costs and expenses associated with the investment bank they have engaged and shall share the costs of the third investment bank, as applicable.

TEXT_SP 9294504v1 7474/36 64

17.3. Following such feasibility analysis, in case CSN decides to pursue the IPO, it shall cause the Company to promptly deliver a notice to all Shareholders: (i) informing the intention to go public; and (ii) stating, in a reasonably detailed basis, the estimated terms and conditions of such offering and the content of the investment banksâ€™ opinion (â€œIPO Noticeâ€).

TERM OF EFFECTIVENESS

18.1. This Agreement is entered into on an irrevocable basis, and shall terminate upon the earlier of: (i) December 31, 2054 (â€œInitial Termâ€); or (ii) in case the percentage of Bound Shares jointly held by the JKTC Parties falls below [*] of the total capital stock of the Company (â€œJKTC Floorâ€) or (iii) upon the occurrence of a termination event under Section 6.6.

For the avoidance of doubt, any dilution resulting from capital increases in which the JKTC Parties were granted preemptive (preferência) or priority (prioridade) rights shall be considered for purposes of reaching the JKTC Floor, irrespective of whether the JKTC Parties opted for exercising such rights or not.

Article 21.
GOVERNING LAW AND DISPUTES RESOLUTION

21.1. This Agreement and the rights and obligations of the Parties hereunder and the transactions contemplated hereby shall be governed by, enforced and interpreted in accordance with the laws of Brazil.

21.2. Any dispute, controversy or claim arising out of or relating to this Agreement ("Dispute") shall be solved by arbitration, in accordance with the following provisions:

21.2.1 The Dispute shall be finally settled under the Rules of Arbitration of the International Chamber of Commerce (the "ICC Rules") in force at the time of the request for arbitration.

21.2.2 The arbitration shall be conducted by 3 (three) arbitrators (“Arbitral Tribunal”), one nominated by the claimant, another one nominated by the respondent, and the two (2) party-appointed arbitrators shall designate a third arbitrator, who shall act as president of the Arbitral Tribunal, within 15 (fifteen) days after the confirmation of the later-appointed of these two

TEXT_SP 9294504v1 7474/36 67

arbitrators. In case there are multiple parties, whether as claimant or as respondent, the multiple claimants, jointly, and/or the multiple respondents, jointly, as the case may be, shall appoint one arbitrator. If any of the three arbitrators is not nominated within the time prescribed in the ICC Rules or above, such arbitrator shall be appointed by the Court of Arbitration of the International Chamber of Commerce (the "ICC Court").

21.2.3 The arbitration shall be held in the City of SÃ£o Paulo, State of SÃ£o Paulo, Brazil, where the arbitral award shall be deemed rendered. The arbitration procedure shall be held in English and in accordance with Brazilian Law, but evidence may be produced by the parties in Portuguese without the need of translation.

21.2.4 The Parties elect the courts of the City of SÃ£o Paulo, State of SÃ£o Paulo, exclusively for granting interim or conservatory measures before the constitution of the Arbitral Tribunal.

21.2.6 The Parties shall keep the confidentiality of each and every information concerning the arbitration.

21.2.7 If one or more Disputes arise under this Agreement or any other Transaction Document, as defined in the Investment Agreement, then any or all such Disputes may be brought into a single arbitration. The ICC Court may, at the request of any of the parties, consolidate the arbitral proceeding with any other pending arbitral proceeding involving this Agreement and/or any other Transaction Document. If one or more arbitrations are already pending with respect to a Dispute under any such agreement, then any party to a new dispute or any subsequently filed arbitration brought under any such agreement may request that such new dispute or any subsequently filed arbitration be consolidated into any prior pending arbitration.

21.2.8 The new dispute or subsequently filed arbitration shall be so consolidated, provided that the ICC Court determines that: (i) the new dispute or subsequently filed arbitration presents significant issues of law or fact common with those in the prior pending arbitration; (ii) no party to the new dispute or prior pending arbitration would be prejudiced; and (iii) consolidation under these circumstances would not result in undue delay for the prior pending arbitration.

21.2.9 The consolidation order shall be final and binding upon all the parties involved in the consolidated proceedings. The arbitrations shall be consolidated into the arbitration that commenced first. The Parties agree that upon such an order of consolidation, they will promptly dismiss any arbitration proceeding, the subject of which has been consolidated into another arbitral proceeding.
