JKTC Top Shareholding Position = ([*]) (“JKTC Top Shareholding Position”).

Where Δ Working Capital of Namisa = ([*])

JKTC Bottom Shareholding Position Post Closing Sale of Shares = ([*] (“JKTC Bottom Shareholding Position Post Closing Sale of Shares”).

Additional CSN Shares Price = [*] * Sale Percentage

For the avoidance of doubt, the Liquidity Event shall be a one time event and shall not be counted twice.

6.2Pre-Money Valuation. The ratio for conversion of the Pre-Money Equity Value – Subscription Bonus into Congonhas Minérios’ 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.

6.3Maximum 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.

6.4Capital 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.

6.5Conversion 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’ 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:

Plan B 37

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

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

JKTC Liquidity Event Final Shareholding Position = [*]

8.7Indemnification 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

Plan B 48

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 Indemnifying Party with respect to such Claim or otherwise provided herein, in which cases no such consent shall be required.

(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

Plan B 49

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.

8.8Survival 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 Closing 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 Closing Date, 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.

8.9Further 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.

8.10The 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).

9.2.8The 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.

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