Date promptly on the same day after receipt of notice thereof from the applicable Borrower pursuant to Section 2.2. By 11:00 a.m. (New York City time) on the relevant Disbursement Date, each Bank shall, subject to the conditions set forth

the earlier of the Commitment Termination Date and the date that the Loan Commitments otherwise terminate; provided that, solely for purposes of this Section 2.4 and solely until the Transaction Closing Date, the Loan Commitment of any
Bank shall be deemed to be equal to the maximum aggregate principal amount that such Bank would be committed to advance to the Borrowers hereunder after application of Section 2.1(g)(i), assuming, for purposes of such application, that Ternium
has borrowed the entire aggregate principal amount of the term loans, if any, that such Bank has committed to make to Ternium under the Ternium Loan Agreement.

automatically be reduced, for all purposes under this Agreement (including Section 2.4), on the last day of the General Advance Availability Period to an amount equal to the excess of U.S.$165,000,000 over the aggregate principal amount of
Fiduciary Trust Advances made on or prior to such date hereunder and under (and as defined in) the Ternium Loan Agreement. 

(b) The Borrowers may at any time terminate, or from time to time reduce, the Total Loan Commitment; provided that each reduction
of the Total Loan Commitment pursuant to this Section shall be in an amount of no less than U.S.$10,000,000.

notice of such date and the amount of the Total Loan Commitment to be reduced (or terminated) on such date.

termination or reduction of the Total Loan Commitment shall be permanent. Each reduction of the Total Loan Commitment shall be applied to reduce the Loan Commitments of the Banks ratably in accordance with the amounts of their respective Loan
Commitments. 

  
 26 

 3. REPAYMENT 
 3.1 Repayment. Except as otherwise expressly provided herein, each Borrower shall repay the entire principal amount of the Loans outstanding as follows: 

(a) Hylsa shall pay the Hylsa Tranche A Loans in six equal installments, each in an amount equal to 14.28% of the
aggregate principal amount of the Hylsa Tranche A Loans outstanding on the Commitment Termination Date, and one additional installment in an amount equal to the balance of such outstanding amount, one such installment to be paid on each
Tranche A Loan Payment Date; provided that any principal amount of the Hylsa Tranche A Loans outstanding on the Tranche A Loan Final Maturity Date shall be paid on such date; 

(b) Hylsa shall pay the Hylsa Tranche B Loans on the Tranche B Loan Final Maturity Date; 

(c) Hylsa or, if the IMSA Assumption Date shall have occurred, IMSA shall pay the IMSA Tranche A Loans in six equal
installments, each in an amount equal to 14.28% of the aggregate principal amount of the IMSA Tranche A Loans outstanding on the Commitment Termination Date, and one additional installment in an amount equal to the balance of such outstanding
amount, one such installment to be paid on each Tranche A Loan Payment Date; provided that any principal amount of the IMSA Tranche A Loans outstanding on the Tranche A Loan Final Maturity Date shall be paid on such date; and

 (d) Hylsa or, if the IMSA Transaction shall have been consummated, IMSA shall pay the IMSA Tranche B
Loans on the Tranche B Loan Final Maturity Date. 
 3.2 Optional Prepayments. Each Borrower may prepay the Loans made to
such Borrower in whole or in part in a principal amount of no less than U.S.$10,000,000 at any time. If either Borrower wishes to make such a prepayment, such Borrower shall, on or before the fifth Banking Day immediately preceding the date such
Borrower wishes to designate for such prepayment, give the Administrative Agent notice of such date and the amount to be prepaid on such date. Such notice shall constitute such Borrower’s irrevocable commitment to prepay such amount on such
date, together with interest accrued thereon to such date and any amounts payable pursuant to Section 3.5. 
 3.3
Mandatory Prepayments. Within five Banking Days after (a) any Debt Incurrence (the “Current Debt Incurrence”) having an aggregate principal amount that, together with the aggregate principal amount of all prior Debt
Incurrences effected during the fiscal year of the Current Debt Incurrence, exceeds U.S.$300,000,000 or (b) any Equity Issuance, the Borrower consummating such Debt Incurrence or Equity Issuance shall prepay the Loans made to such Borrower in
an aggregate amount equal to 100% of the Net Available Proceeds thereof, such prepayment to be effected in each case in the manner and to the extent specified in the last sentence of Section 3.4, provided that, if such prepayment is
required to be made before the Loan Commitments have expired or been terminated, the Loan Commitments shall instead be permanently reduced in the same amount (and to the extent that, after giving effect to such permanent reduction, the aggregate
principal amount of the Loans would exceed the aggregate amount of the Loan Commitments, such Borrower shall prepay the Loans made to such Borrower as set forth above in an aggregate amount equal to such excess). 

  
 27 

 3.4 Other Payment Provisions. Any partial repayment or prepayment hereunder shall be
allocated among the Banks on the basis of their respective Pro Rata Shares. If either Borrower makes any payment of principal with respect to any Loan on any day that is not an Interest Payment Date, such Borrower shall reimburse each Bank in
Dollars on demand for all reasonable losses (other than loss of anticipated profits or margin) arising from the reemployment of funds obtained, or the termination, liquidation or redeployment of deposits received, from third parties;
provided, however, that such Borrower shall not be required to make any additional payments pursuant to this Section if such repayment or prepayment is the result of the events or circumstances contemplated in Section 3.3,
Section 3.5, Section 9.14 or Section 14.4. For the purpose of calculating losses payable to any Bank under this Section 3.4, such Bank shall be deemed to have (a) actually funded its Loans through the purchase of a deposit
bearing interest at LIBOR in an amount equal to the amount of its Loan Commitment and having a maturity comparable to the relevant Interest Period, and (b) reemployed the funds by depositing them at LIBOR for a period having a maturity
comparable to the number of days from (x) the day of prepayment through (y) the last day of the relevant Interest Period. Any reimbursement request pursuant to this Section 3.4 shall be accompanied by a certificate of the relevant
Bank setting forth in reasonable detail the basis for calculating such losses and shall be delivered to the applicable Borrower and shall be conclusive and binding for all purposes hereunder, absent manifest error. Any prepayments of the Loans
hereunder shall be applied, first, to the Tranche B Loans and, second, when the Tranche B Loans shall have been paid in full, pro rata to the remaining installments of the Tranche A Loans (it being understood that, in
the event of any prepayment occurring during the period from the IMSA Assumption Date until, if the Transaction Merger shall become effective, the Transaction Merger Date, the amount of any such prepayment made by Hylsa shall be applied to the Hylsa
Tranche B Loans or the Hylsa Tranche A Loans, as applicable, and the amount of any such prepayment made by IMSA shall be applied to the IMSA Tranche B Loans or the IMSA Tranche A Loans, as applicable). 

3.5 Illegality. (a) If any Bank determines at any time that any law, regulation or treaty or any change therein or in the
interpretation or application thereof by any competent Governmental Authority makes or will make it unlawful for such Bank to fulfill its commitment pursuant to Section 2.1, to maintain any of its Loans or to claim or receive any amount payable
to it hereunder, such Bank shall give notice of such determination to the applicable Borrower and the Administrative Agent, whereupon the obligations of such Bank hereunder shall terminate. If any such notice is given after the initial Disbursement
Date, each Borrower shall, to the extent any such law, regulation, treaty, change, interpretation or application requires such Loans to be prepaid, either (i) cause a designee of such Borrower (which may be an Affiliate of such Borrower,
provided that no such Affiliate shall have any right to vote on any amendment, waiver, action or other matter under or in connection with this Agreement, nor any right to participate in any meetings or deliberations of or receive
communications among the Banks with respect thereto and the consent of any such Affiliate shall not be required for purposes of any amendment or waiver under Section 15.7) to purchase such Loans of such Bank in accordance with Section 11.1
(any such designee to be reasonably acceptable to the Administrative Agent) for a purchase price equal to the outstanding principal amount of such Loans, accrued interest thereon and all other amounts payable to it hereunder or such other amount as
such Bank may in its sole discretion agree with such designee (it being understood and agreed that neither the Administrative Agent nor any Bank shall have any obligation to purchase such Loans) or (ii) prepay such Loans of such Bank made to
such Borrower on the Interest Payment Date next succeeding the date such notice is given (or on such earlier date as such Bank determines and certifies to be necessary in order to enable it to comply with such law, regulation, treaty or change),
without premium but together with interest accrued to the date of prepayment on such Loans and all other amounts then payable to such Bank by such Borrower hereunder. 

  
 28 

 (b) Before demanding prepayment pursuant to this Section 3.5, the affected Bank shall
use its reasonable best efforts to take any and all reasonable steps and action that would not, in its good faith judgment, be materially disadvantageous to such Bank, to mitigate the effect of any unlawfulness and/or avoid the need for such
prepayment, including (i) designating a different Lending Branch or changing the jurisdiction of its Lending Branch; (ii) selling a participating interest in the relevant Loans at par or such other price as such Bank may in its sole
discretion agree with the relevant purchaser; and/or (iii) assigning and transferring its interests, rights and obligations under such Loans to a substitute bank on the terms described in subsection (a) above. 

(c) Any demand for prepayment pursuant to this Section 3.5 submitted to the applicable Borrower by the affected Bank shall describe
in reasonable detail the event by reason of which it is making any such demand and the date of occurrence of such event, and contain a statement and representation by such Bank that it is treating its other similarly situated debtors in a consistent
manner and provide certification that such Bank is in compliance with the provisions of subsection (b) above. 
 (d)
Neither Borrower shall have any obligation to indemnify any Bank under this Section 3.5 for any losses or expenses arising as a result of any prepayment made by such Borrower under this Section 3.5 or non-disbursement of the Loans as
contemplated in this Section 3.5. 
 3.6 No Reborrowing. Amounts paid or prepaid pursuant to any provisions of this
Agreement may not be reborrowed. 
 4. INTEREST 
 4.1 Basic Rate. 
 (a) Except as otherwise expressly provided in
Sections 4.2 and 4.3, interest shall accrue on the Loans during each Interest Period, from and including the first day of such Interest Period to but excluding the last day thereof, at a rate per annum equal to the sum of the Margin and LIBOR
for such Interest Period (the “Euro-Dollar Rate”). 
 (b) Except as otherwise expressly provided herein,
accrued interest on each Loan shall be payable on each Interest Payment Date and upon any repayment or prepayment of principal hereunder, on the amount of such repayment or prepayment on the date thereof. 

  
 29 

 (c) The Administrative Agent shall give notice to the applicable Borrower and the Banks of
LIBOR promptly after each determination thereof (and, in any case, no later than three Banking Days thereafter). 
 4.2
Default Interest. Upon the occurrence and during the continuance of an Event of Default of the kind referred to in Section 10.1(a), (a) interest shall accrue on the unpaid principal amount of each Loan owing to each Bank at a rate
equal at all times to the sum of (i) 200 basis points (2.00%) and (ii) the rate per annum required to be paid on such Loan pursuant to Section 4.1(a) or 4.3, and (b) to the extent permitted by applicable law, interest
shall accrue on the amount of any interest, fee or other amount payable hereunder that is not paid when due during the period from and including the due date thereof, to but excluding the date such amount is paid, at a rate per annum equal for each
day in such period to the sum of (i) 200 basis points (2.00%), (ii) the Margin and (iii) LIBOR for a one-month period for value on such day. Interest accruing pursuant to this Section shall be payable on demand of the Administrative
Agent made upon request and on behalf of any Bank. 
 4.3 Alternative Rate Loans. In the event that the Administrative
Agent is advised by the Reference Banks that deposits in Dollars (in the applicable amounts) are not being offered to the Reference Banks in the London interbank market for such Interest Period (in circumstances where quotes are requested for
determining LIBOR under the definition thereof), the Administrative Agent shall forthwith give notice thereof to the applicable Borrower and to the Banks, whereupon (a) the obligation of each Bank to continue its outstanding Loans at the
Euro-Dollar Rate shall be suspended and (b) all outstanding Loans bearing interest at the Euro-Dollar Rate shall be converted into Alternative Rate Loans on the last day of the then current Interest Period applicable thereto (such Alternative
Rate Loans bearing interest at the Alternative Rate in effect on the second Banking Day next preceding the commencement of each Interest Period plus the Margin); provided that upon the Administrative Agent being able to determine LIBOR in
accordance with the definition thereof, the Administrative Agent shall notify the applicable Borrower thereof and such Borrower shall notify the Administrative Agent of the date on which such Borrower wishes the outstanding Alternative Rate Loans
made to such Borrower converted into Loans bearing interest at the Euro-Dollar Rate. 
 4.4 Interest Period Notice. Each
Borrower shall, prior to 11:00 a.m. (New York City time), at least three Banking Days prior to the commencement of each Interest Period, give the Administrative Agent irrevocable notice of such Borrower’s election for such Interest Period to
have a duration of one, three or six months. Upon receipt of such notice from the applicable Borrower, the Administrative Agent shall promptly notify each Bank thereof. In the event that either Borrower fails to timely select in accordance herewith
the duration of any Interest Period, such Borrower will be deemed to have selected an Interest Period of a duration equal to the shorter of (i) the period of time remaining until the next succeeding Loan Payment Date, and (ii) the same
duration as the immediately preceding Interest Period. 
 4.5 Exchange of Notes. Promptly upon (i) the
conversion of the installment of any Loan covered by a Principal Note to an Alternative Rate Loan pursuant to Section 4.3 and/or (ii) the election of a Borrower pursuant to Section 4.4 to change the duration of an Interest Period for
the installment of any Loan covered by a Principal Note, in each case upon the request of any Bank and in accordance with Section 15.4, the applicable Borrower shall execute and deliver to the Custodian for the account of such Bank, in exchange
for such Principal Note theretofore delivered to such Bank a new Principal Note payable to the relevant Bank, in a principal amount equal to the principal amount of such installment and otherwise duly completed. 

  
 30 

 5. NO SETOFF, COUNTERCLAIM; TAXES 

5.1 No Setoff, Counterclaim or Withholding; Gross Up. (a) Each payment by or on behalf of any Obligor under this Agreement or
the Notes (including any applicable fees) shall be made without setoff or counterclaim, and without withholding or deduction on account of any present or future Taxes imposed by or within Mexico or any political subdivision or taxing authority
thereof or therein (including any withholding tax on interest payments); provided, however, that if such Taxes are required to be withheld from any such payment, the applicable Obligor shall cause such withholding to be made, make
payment of the amount withheld to the appropriate Governmental Authority when due and forthwith pay such additional amount as may be necessary to ensure that the net amount actually received by each Bank and the Administrative Agent, free and clear
of such Taxes is equal to the amount that such Bank or the Administrative Agent (as the case may be) would have received had no such Taxes been withheld; provided further, however, that (i) in the event of the redesignation
of any Bank’s Loans to a Lending Branch in another jurisdiction, such Bank shall not be entitled to receive, immediately following such redesignation, any greater amount, paid as additional amounts, than it would have been entitled to receive
had such redesignation not taken place, (ii) notwithstanding anything to the contrary provided elsewhere in this Agreement, the Obligors shall not be liable to make any payment to any Bank or taxing authority pursuant to this Section 5.1
for, or in relation to, Taxes, franchise taxes, and any similar taxes imposed on (or assessed on the basis of) the overall net income, profits or capital of such Bank (or its Lending Branch) and any Taxes that would not be imposed but for a
connection between such Bank and Mexico or any political subdivision thereof or taxing authority therein (other than a connection arising solely by virtue of the activities of such Bank (or its Lending Branch) pursuant to this Agreement, including
making and holding Loans and receiving payments in connection therewith) and (iii) if any Obligor pays any additional amount pursuant to this Section 5.1 and any Bank actually receives a tax refund or a credit against such Bank’s tax
liabilities as a result of such payment by such Obligor, such Bank shall (provided that no Default or Event of Default shall have occurred and be continuing) promptly pay to such Obligor an amount that such Bank determines in its sole
discretion is equal to (A) in the case of a tax refund, the amount of such refund actually received by such Bank as a result of such payment by such Obligor, and (B) in the case of a credit against its tax liabilities, the net tax benefit
obtained by such Bank as a result of such payment by such Obligor; provided, however, that (1) with respect to any Bank that on the date of this Agreement would not be entitled to a tax credit or refund, the preceding obligations
shall only be applied to the extent that any such Bank becomes entitled to a tax credit or refund as a result of any law or regulation enacted or adopted subsequent to the date of this Agreement which entitles such Bank thereto, and (2) with
respect to any Bank that on the date of this Agreement would be entitled to a tax credit or refund, the preceding obligation shall only be applicable to the extent that such Bank becomes entitled to a tax credit or refund as a result of any law or
regulation enacted or adopted subsequent to the date of this Agreement which increases the amount of such tax credit or refund to which such Bank is entitled and only with respect to such increase. Each Obligor may request in writing that any Bank
claim a tax credit or refund; however, whether or not such Bank claims any such tax credit or refund shall be in the reasonable discretion of such Bank and at no cost to the Bank (which if incurred shall be reimbursed by the applicable Obligor). All
such Taxes shall be paid by the applicable Obligor prior to the date on which penalties attach thereto or interest accrues thereon; provided, however, that, if any such penalties or interest become due, the applicable Obligor shall
make prompt payment thereof to the appropriate Governmental Authority. If the Administrative Agent or any Bank pays any amount in respect of such Taxes, penalties or interest, the Obligors shall reimburse the Administrative Agent or such Bank in
Dollars for such payment on demand. If any Obligor pays any such Taxes, penalties or interest, it shall deliver copies of official tax receipts evidencing such payment to the Administrative Agent on or before the 30th day after such payment.

  
 31 

 (b) Notwithstanding anything herein to the contrary, the Obligors shall not be required
to pay amounts under Section 5.1 to any Bank (other than a Mexican Bank) that is not registered as a foreign financial institution with the Mexican Ministry of Finance and Public Credit for the purposes of Article 195, Section I (or any

that, individually or in the aggregate, would not be reasonably expected to result in a Material Adverse Effect. 
 (i) The obligations of such Borrower under this Agreement rank, and its obligations under the other Loan Documents to which such Borrower is a party will rank in priority of payment at least pari

 37 

 (j) Hylsa’s consolidated financial statements as at December 31,
2006 for the fiscal year ended on such date, and for the three-month period ended on March 31, 2007, are complete and correct, have been prepared in accordance with Mexican NIF, and fairly present in all material respects the consolidated
financial condition of Hylsa as at such dates and the results of its consolidated operations for such fiscal year or period; Hylsa’s consolidated annual financial statements as at December 31, 2006 and for the fiscal year ended on such
date have been audited by PriceWaterhouseCoopers; and no financial statements have been prepared by Hylsa for any period subsequent to March 31, 2007, except such as have been delivered pursuant to Section 9.6. 

(k) Since December 31, 2006, there has been no event, development or circumstance that has had or would reasonably
be expected to have a material adverse effect on (i) the business, assets, property or financial condition of such Borrower and its Subsidiaries taken as a whole, or (ii) the validity or enforceability of any of the Loan Documents to which
such Borrower is a party or the rights or remedies of the Administrative Agent and the Banks hereunder or thereunder, excluding, in each case, any event or circumstance that results solely from (u) the announcement, the pendency or the
consummation of the IMSA Transaction, (v) changes in any relevant accounting methodology or official interpretations thereof after the date hereof that apply to such Borrower or any of its Subsidiaries, (w) changes in the economy or
financial markets generally in the United States, Mexico or other countries in which such Borrower and its Subsidiaries operate, (x) changes that are the result of factors generally affecting the principal industries and geographic areas in
which such Borrower and its Subsidiaries operate, (y) the commencement, occurrence, continuation or escalation of any war, armed hostilities or acts of terrorism in any geographic region in which such Borrower and its Subsidiaries operate; and
(z) a decline in the trading price of the shares of such Borrower and/or a failure by such Borrower to meet any estimates of revenues or earnings. 
 (l) The execution and delivery of the Loan Documents to which such Borrower is a party are not subject to any tax, duty, fee or other charge, including any registration or transfer tax, stamp duty or
similar levy, imposed by or within Mexico or any political subdivision or taxing authority thereof or therein. 

(m) No withholding in respect of any taxes imposed by or within Mexico or any political subdivision or taxing authority
thereof or therein is required to be made from any payment by such Borrower under the Loan Documents to which such Borrower is a party, except that payments in respect of the Loan Documents made to the Administrative Agent or the Banks, to the
extent such payments represent interest and commitment fees, will be subject to withholding in respect of Mexican income tax at the rate in effect at the time such payments are made. 

(n) Neither such Borrower nor the property of such Borrower has any right of immunity on the ground of sovereignty or
otherwise from jurisdiction, attachment (before or after judgment) or execution in respect of any action or proceeding relating in any way to the Loan Documents to which such Borrower is a party that may be brought in the courts of Mexico.

  
 38 

 (o) The execution or signing (as the case may be) and the delivery and
performance by such Borrower of the Loan Documents to which such Borrower is a party constitute commercial transactions and such Borrower is subject to civil and commercial law with respect to its obligations under the Loan Documents to which such
Borrower is a party. 
 (p) Such Borrower has filed all tax returns required by law to be filed by it and has
paid all Taxes levied upon it or any of its properties, assets, income or franchises which are due and payable, except the filing of such tax returns or the payment of such Taxes where the failure so to file or to pay, individually or in the
aggregate, would not be reasonably be expected to have a Material Adverse Effect, and except for Taxes being contested in good faith and for which appropriate reserves have been established if required by Applicable NIF. There are no tax liens upon
any material assets of such Borrower except for statutory liens for Taxes accruing but not yet due and payable. The charges, accrual and reserves on the books of such Borrower in respect of Taxes for all periods are adequate in the reasonable
opinion of such Borrower, and such Borrower does not know of any unpaid assessment for additional taxes for any period or any basis for any such assessment for which adequate provision has not been made in its account. 

(q) None of the reports, financial statements, documents, certificates, instruments or other written (including by
electronic transmission) information (including the information memorandum dated May 2007) furnished by or on behalf of such Borrower to the Banks in connection with this Agreement contains any untrue statement of a material fact or omits to state a
material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. There is no fact known (other than matters of a general economic or political nature which do not affect such Borrower
uniquely) to such Borrower which, individually or in the aggregate, has had or would reasonably be expected to have a Material Adverse Effect which has not been disclosed in the documents, certificates and instruments delivered to the Banks by or on
behalf of such Borrower specifically for use in connection with the transactions contemplated by this Agreement. 
 (r) Such Borrower will use the proceeds of the Loans solely as set forth in Section 9.1. None of the transactions contemplated in this Agreement (including the borrowings hereunder and the use of the
proceeds thereof) will violate or result in a violation of Section 7 of the Securities Exchange Act of 1934, as amended (or any regulations issued pursuant thereto, including Regulations T, U and X of the Board of Governors of the Federal
Reserve System, 12 C.F.R., Chapter II, as amended). Margin Stock does not constitute more than 25% of the value of the consolidated assets of such Borrower and its Material Subsidiaries, and such Borrower does not have any present intention that
Margin Stock will constitute more than 25% of the value of such assets.

(normas técnicas) relating to the protection of human health and safety, the environment or hazardous or toxic substances or wastes, pollutants or contaminants (“Environmental Laws”), (ii) has received all
permits, licenses and other approvals required of it under applicable Environmental Laws to conduct its business and (iii) is in compliance with all terms and conditions of each such permit, license and approval, except where such noncompliance
with such applicable Environmental Laws, failure to receive such required permits, licenses or approvals or failure to comply with the terms and conditions of such permits, licenses or approvals would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect; and in the reasonable judgment of such Borrower the costs and liabilities associated with the effect of Environmental Laws on such Borrower (including capital or operating expenditures
required with respect thereto) would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 
 (w) This Agreement is, and upon execution each of the other Loan Documents to which such Borrower is a party will be, in proper legal form for the enforcement thereof in Mexico against such Borrower;
provided that in the event of any legal proceedings brought in the courts of Mexico, a Spanish translation of the documents required in such proceedings that are in the English language prepared by a court-approved translator would have to be
approved by the court after such Borrower has been given an opportunity to be heard with respect to the accuracy of the translation and proceedings would thereafter be based on such translated documents. To ensure the enforceability, priority or
admissibility in evidence in Mexico of this Agreement or any of the other Loan Documents, it is not necessary that this Agreement or any of the other Loan Documents or any other document or instrument be registered, recorded or filed with any court
or other authority in Mexico or be notarized or that any stamp or similar tax be paid on or in respect of this Agreement or any of the other Loan Documents.

Public Credit for purposes of Article 195, Section I (or any successor provision), of the Mexican Income Tax Law (Ley del Impuesto sobre la Renta) for so long as such requirement remains applicable and that is (or the main office of which is,
if acting through a branch or agency) in a jurisdiction with which Mexico has entered into a treaty for the avoidance of double taxation that is in effect (“Purchasing Bank”), pursuant to, and subject to the terms of, an Assignment

(a) any transfer or assignment by a Bank to any Purchasing Bank, other than to an Affiliate of such assigning Bank or to another Bank or an Affiliate of another Bank, of a portion of its rights hereunder or under its Notes shall not be for an
amount less than U.S.$10,000,000 or a higher integral multiple of U.S.$500,000 in each instance, (b) each such assignment shall be of a uniform, and not varying, percentage of all rights and obligations under this Agreement, (c) each such
assignment shall be of an equal percentage of Hylsa Tranche A Loans, Hylsa Tranche B Loans, IMSA Tranche A Loans and IMSA Tranche B Loans, (d) the Administrative Agent shall have consented to such proposed assignment (which
consent shall not be unreasonably withheld), unless the assignment is to an Affiliate of the assigning Bank or to another Bank or an Affiliate of another Bank, (e) the Administrative Agent shall have notified the Borrowers of such proposed
assignment and provided contact information for such Purchasing Bank to the Borrowers and, unless the assignment is to an Affiliate of the assigning Bank or to another Bank or an Affiliate of another Bank (so long as any such assignment to an
Affiliate of the assigning Bank, another Bank or an Affiliate of another Bank does not result in amounts payable to such Purchasing Bank under Section 5.1(a) or Section 14.4, immediately after giving effect to such assignment, being
greater than the amount payable to or for the benefit of the assigning Bank), or an Event of Default has occurred and is continuing, the Borrowers shall have notified the assigning Bank and the Administrative Agent, within ten Banking Days of the
Borrowers’ receipt of such notice, of the Borrowers’ approval of such assignment (such approval not to be unreasonably withheld or delayed; it being understood that it would be reasonable for the Borrowers to withhold their approval if,
immediately after giving effect to such assignment, the amounts payable to or for the benefit of the Purchasing Bank under Section 5.1(a) or Section 14.4 would be greater than the amounts payable to or for the benefit of the assigning
Bank on the date of such assignment) and if the Borrowers have not notified the assigning Bank and the Administrative Agent of their approval or disapproval of such assignment by such date, the Borrowers shall be deemed to have given their approval

Assignment Agreement, (ii) delivery of an executed copy thereof to the Borrowers and the Administrative Agent, (iii) receipt by the Administrative Agent of a recordation fee of U.S.$5,000, provided that no such fee shall be payable

Bank party to this Agreement and shall have all the rights of a Bank under this Agreement to the same extent as if it were an original party hereto, and no further consent or action by the Borrowers, the Banks or the Administrative Agent shall be
required. Such Assignment Agreement shall be deemed to amend this Agreement to the extent, and only to the extent, necessary to reflect the addition of such Purchasing Bank as a Bank. Promptly after the consummation of any transfer of all or any
part of a Loan to a Purchasing Bank pursuant hereto, the transferor Bank, the Administrative Agent and the Borrowers shall make appropriate arrangements so that replacement Notes are issued to such transferor Bank, if applicable, and new Notes are
issued to such Purchasing Bank, in each case in principal amounts reflecting the principal amount of the Loan so transferred. No Note shall be assigned except in connection with the assignment by a Bank of such Bank’s related rights under this
Agreement. 

  
 52 

 11.2 Participations. Any Bank may at any time sell to one or more banks or financial
institutions (each a “Participant”) participating interests in the Loans owing to or Notes held by such Bank or any other interest of such Bank hereunder. Notwithstanding any such sale by a Bank of participating interests to a
Participant, such Bank’s rights and obligations under this Agreement shall remain unchanged, such Bank shall remain solely responsible for the performance thereof, such Bank shall remain the holder of any such Notes for all purposes under this
Agreement (except as expressly provided below), and the Borrowers and the Administrative Agent shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under this Agreement. The Borrowers
agree that each Participant shall be entitled to the benefits of Sections 5.1 and 14.4; provided that no Participant shall be entitled to receive any greater amount pursuant to such sections than the transferor Bank would have been
entitled to receive in respect of the amount of the participating interest transferred by such transferor Bank to such Participant had no such transfer occurred. In no event shall a Bank that sells a participation agree with the Participant to take
or refrain from taking any action hereunder or under any Notes and each Bank agrees that any agreement between such Bank and any such Participant in respect of such participating interest shall provide that such Bank shall retain the sole right,
responsibility and discretion to enforce the obligations of the Borrowers hereunder or under any Notes including the right to agree to any amendment, supplement, waiver or modification to this Agreement or any other document delivered hereunder;
provided that such Bank may agree with the Participant that it will not, without the consent of the Participant, agree to extend the final maturity of any amount owing hereunder or under the Notes or any regularly scheduled installment
thereof or reduce the rate or extend the time of payment of interest thereon or fees payable hereunder or reduce the principal amount thereof (except as expressly provided herein or in the Notes) or increase the amount of such Bank’s Loans
hereunder or modify such Bank’s Pro Rata Share hereunder. 

  
 53 

 11.3 Disclosure of Information. Each Borrower authorizes each Bank to disclose to any
Participant or Purchasing Bank (each, a “Transferee”) and any prospective Transferee any and all financial and other information in such Bank’s possession concerning such Borrower that has been delivered to such Bank by either
Borrower pursuant to this Agreement or which has been delivered to such Bank by either Borrower prior to entering into this Agreement in connection with such Bank’s credit evaluation of the Borrowers; provided that no such information
shall be furnished to a Transferee or a prospective Transferee that has not agreed in writing to be bound by the terms of Section 15.15. 
 11.4 Pledge by Banks. Any Bank may at any time pledge, or assign a security interest in, all or any portion of its rights under this Agreement to secure obligations of such Bank to any Federal
Reserve Bank in accordance with Regulation A of the Board of Governors of the U.S. Federal Reserve System (or any successor regulation), and this Article 11 shall not apply to any such pledge or assignment of a security interest; provided
that no such pledge or assignment of a security interest shall release a Bank from any of its obligations hereunder or substitute any such pledgee or assignee for such Bank as a party hereto. 
 12. APPLICATION, DISTRIBUTION AND SHARING OF PAYMENTS 
 12.1 Application
and Distribution of Payments. All payments received by the Administrative Agent from any Obligor pursuant to any Loan Document to which such Obligor is a party shall, regardless of the application designated by such Obligor, be applied, first,
to any sum due and owing pursuant to Section 3.4 or Article 14, second, to any fees due and owing to the Administrative Agent, third, to any interest or fees due and owing on the Loans and, fourth, to the repayment of the principal of the
Loans. Such payments shall be distributed promptly upon receipt among the Administrative Agent and the Banks in like funds as received, in proportion to the respective amounts of the sums payable pursuant to Section 3.4 or Article 14, fees
payable to the Administrative Agent, interest, fees or principal, as the case may be, at the time due and owing to each of them. 
 12.2 Sharing of Payments. If any Bank at any time obtains total or partial payment of any amount payable hereunder other than pursuant to Section 3.4, 3.5, 5.1 or 14.4 or by distribution by
the Administrative Agent pursuant to Section 12.1, such Bank shall forthwith pay to the Administrative Agent the amount so obtained, and the Administrative Agent shall apply and distribute such amount pursuant to the provisions of
Section 12.1 as if such amount were a payment made by the applicable Borrower; provided, however, that, if any Bank at any time obtains total or partial payment of any amount payable hereunder by exercising a right of setoff (if
any), banker’s lien or counterclaim, such Bank shall forthwith purchase from the other Banks such participations in the Loans made by such other Banks as shall be necessary to cause such purchasing Bank to share such amount ratably with such
other Banks; and provided further, however, that, if all or any portion of such amount is thereafter recovered from such purchasing Bank, the purchase shall be rescinded and the purchase price restored to the extent of such
recovery, but with such adjustments of interest as shall be equitable. Any Bank so purchasing a participation from another Bank pursuant to this Section may, to the fullest extent permitted by law, exercise all its rights of payment with respect to
such participation as fully as if such Bank were the direct creditor of the applicable Borrower in the amount of such participation. Nothing herein contained shall in any way affect the right of any Bank to retain any amount obtained with respect to
indebtedness other than indebtedness under this Agreement or the Notes. 

  
 54 

 13. THE ADMINISTRATIVE AGENT 
 13.1 Appointment. Each Bank hereby irrevocably designates and appoints the Administrative Agent as the agent of such Bank under this Agreement and the other Loan Documents, and each such Bank
irrevocably authorizes the Administrative Agent, in such capacity, to take such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such duties as are expressly delegated
to the Administrative Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in this Agreement, the
Administrative Agent shall have no duties or responsibilities, except those expressly set forth herein, or any fiduciary relationship with any Bank, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be
read into this Agreement or any other Loan Document or otherwise exist against the Administrative Agent. 
 13.2 Delegation
of Duties. The Administrative Agent may execute any of its duties under this Agreement and the other Loan Documents by or through agents or attorneys in fact and shall be entitled to advice of counsel concerning all matters pertaining to such
duties. The Administrative Agent shall not be responsible for the negligence or misconduct of any agents or attorneys in fact selected by it with reasonable care. 
 13.3 Exculpatory Provisions. Neither the Administrative Agent nor any of its officers, directors, employees, agents, attorneys in fact or affiliates shall be (i) liable for any action lawfully
taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Loan Document (except to the extent that any of the foregoing are found by a final and nonappealable decision of a court of competent
jurisdiction to have resulted from its or such Person’s own gross negligence or willful misconduct) or (ii) responsible in any manner to any of the Banks for any recitals, statements, representations or warranties made by any Borrower or
any officer thereof contained in this Agreement or any other Loan Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Administrative Agent under or in connection with, this Agreement
or any other Loan Document or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or for any failure of any party thereto to perform its obligations hereunder or thereunder.
The Administrative Agent shall not be under any obligation to any Bank to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect
the properties, books or records of any Borrower or any of such Borrower’s Subsidiaries. 

  
 55 

 13.4 Reliance by Administrative Agent. The Administrative Agent shall be entitled to
rely, and shall be fully protected in relying, upon any instrument, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including counsel to any Borrower), independent accountants and other experts selected by the Administrative
Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Banks (or, if so specified by
this Agreement, all Banks) as it deems appropriate or it shall first be indemnified to its satisfaction by the Banks against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. The
Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Required Banks (or, if so specified by this Agreement, all
Banks), and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Banks and all future holders of the Loans. 
 13.5 Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless the Administrative Agent has
received notice from a Bank or either Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default.” In the event that the Administrative Agent receives such a
notice, the Administrative Agent shall give notice thereof to the Banks. The Administrative Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Banks (or, if so specified by
this Agreement, all Banks or any other instructing group of Banks specified by this Agreement); provided that unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Banks. 

13.6 Non-Reliance on Administrative Agent and Other Banks. Each Bank expressly acknowledges that neither the Administrative Agent
nor any of its officers, directors, employees, agents, attorneys in fact or affiliates have made any representations or warranties to it and that no act by the Administrative Agent hereafter taken, including any review of the affairs of any Borrower
or any affiliate of any Borrower, shall be deemed to constitute any representation or warranty by the Administrative Agent to any Bank. Each Bank represents to the Administrative Agent that such Bank has, independently and without reliance upon the
Administrative Agent or any other Bank, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness
of the Borrowers and their affiliates and made its own decision to make its Loans hereunder and enter into this Agreement. Each Bank also represents that it will, independently and without reliance upon the Administrative Agent or any other Bank,
and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make
such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Borrowers and their affiliates. Except for notices, reports and other documents expressly
required to be furnished to the Banks by the Administrative Agent hereunder, the Administrative Agent shall not have any duty or responsibility to provide any Bank with any credit or other information concerning the business, operations, property,
condition (financial or otherwise), prospects or creditworthiness of any Borrower or any of such Borrower’s affiliates that may come into the possession of the Administrative Agent or any of its officers, directors, employees, agents, attorneys
in fact or affiliates. 

  
 56 

 13.7 Indemnification. The Banks agree to indemnify the Administrative Agent in its
capacity as such (to the extent not reimbursed by any Borrower and without limiting the obligation of each Borrower to do so), ratably according to their respective Pro Rata Shares in effect on the date on which indemnification is sought under this
Section (or, if indemnification is sought after the date upon which the Loan Commitments shall have terminated and the Loans shall have been paid in full, ratably in accordance with such Pro Rata Shares immediately prior to such date), from and
against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (whether before or after the payment of the Loans) be imposed on,
incurred by or asserted against the Administrative Agent in any way relating to or arising out of, the Loan Commitments, this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the
transactions contemplated hereby or thereby or any action taken or omitted by the Administrative Agent under or in connection with any of the foregoing; provided that no Bank shall be liable for the payment of any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements that are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the Administrative Agent’s
gross negligence or willful misconduct. The agreements in this Section shall survive the payment of the Loans and all other amounts payable hereunder. 
 13.8 Non Receipt of Funds by Administrative Agent. (a) Unless the Administrative Agent has received written notice from the applicable Borrower prior to the date on which any payment by such
Borrower is due hereunder that such Borrower does not intend to make such payment as and when due, the Administrative Agent may assume that such Borrower has so made such payment and, in reliance upon such assumption, the Administrative Agent may
(but shall not be required to) make available to each Bank on the date such payment is due an amount equal to the portion of such assumed payment that such Bank is entitled to hereunder. If the applicable Borrower has not in fact made such payment
to the Administrative Agent, such Bank shall, on demand, repay to the Administrative Agent the amount so made available to it, together with interest on such amount accrued for each day from and including such payment date to but excluding the date
of such repayment at a rate per annum determined by the Administrative Agent to be the Administrative Agent’s overnight offered rate for a deposit in Dollars in the London interbank market for value on such day. 

  
 57 

 (b) On each Disbursement Date, the Administrative Agent shall be entitled to assume that
each Bank (other than any Bank that has given the Administrative Agent notice to the contrary) has made funds available to the Administrative Agent as required by Section 2.3, and the Administrative Agent, acting in reliance upon such
assumption, may (but shall not be required to) credit funds to the applicable Borrower in an amount equal to the aggregate of such funds of all Banks from which no such notice has been received. If any Bank that has not given such notice fails to
make funds available as required by Section 2.3 (each such Bank, a “Defaulting Bank”) and the Administrative Agent has credited to the applicable Borrower an amount equal to such aggregate of funds required by Section 2.3,
the Administrative Agent shall be entitled at its option to recover an amount equal to such funds of such Defaulting Bank on demand from either such Defaulting Bank or such Borrower (without prejudice to the rights of such Borrower against such
Defaulting Bank; it being understood that the Administrative Agent shall make such demand on such Defaulting Bank prior to making any such demand on such Borrower, and such Defaulting Bank shall not, solely by each Borrower’s agreement in this
sentence be relieved of its obligations to each Borrower for its failure to make its Advance available), together with interest on such amount accrued for each day from and including the applicable Disbursement Date to but excluding the date of such
recovery at (i) if recovered from such Defaulting Bank, a rate per annum determined by the Administrative Agent to be the Administrative Agent’s overnight offered rate for a deposit in Dollars in such amount in the London interbank market
for value on such day, and (ii) if recovered from the applicable Borrower, the then applicable Eurodollar Rate or Alternative Rate, if the terms of Section 4.3 shall apply; provided, that, if the Administrative Agent shall recover
such corresponding amount from such Defaulting Bank (i) such amount (excluding interest) recovered will constitute such Defaulting Bank’s Loan for purposes of this Agreement and (ii) if the Administrative Agent shall have also
recovered such amount from the applicable Borrower, the Administrative Agent shall thereupon promptly remit to the applicable Borrower such amount (including interest) recovered from such Borrower not to exceed the amount (including interest)
recovered from such Defaulting Bank. 
 13.9 Administrative Agent in its Individual Capacity. The Administrative Agent
and its affiliates may make loans to, accept deposits from and generally engage in any kind of business with either Borrower and any of its affiliates as though the Administrative Agent were not acting as the Administrative Agent hereunder. With
respect to its Loans made or renewed by it, the Administrative Agent shall have the same rights and powers under this Agreement and the other Loan Documents as any Bank and may exercise the same as though it were not acting as the Administrative
Agent hereunder, and the terms “Bank” and “Banks” shall include the Administrative Agent in its individual capacity. 
 13.10 Successor Administrative Agent. The Administrative Agent may resign as Administrative Agent upon 30 days’ notice to the Banks and the Borrowers. If the Administrative Agent shall resign
as Administrative Agent under this Agreement and the other Loan Documents, then the Required Banks shall appoint from among the Banks a successor agent for the Banks, which successor agent shall (unless an Event of Default under Section 10.1(a)
or Section 10.1(g) with respect to either Borrower shall have occurred and be continuing) be subject to approval by the Borrowers (which approval shall not be unreasonably withheld or delayed, it being understood that it would be
reasonable for either Borrower to withhold its approval if the successor agent is not a commercial bank organized under the laws of the United States of America, or has a combined capital and surplus of less than U.S.$250,000,000), whereupon such
successor agent shall succeed to the rights, powers and duties of the Administrative Agent, and the term “Administrative Agent” shall mean such successor agent effective upon such appointment and approval, and the former Administrative
Agent’s rights, powers and duties as Administrative Agent shall be terminated, without any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement or any holders of the Loans. If no
successor agent has accepted appointment as Administrative Agent by the date that is 30 days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon
become effective and the Banks shall assume and perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Required Banks appoint a successor agent as provided for above; provided that, until the
appointment of a successor agent shall become effective, each Borrower shall remain obligated to pay to the Administrative Agent any fees payable under Section 2.4(b), and the Administrative Agent shall continue to have all of the rights
accorded to it as the Administrative Agent under this Agreement and the other Loan Documents; provided, however, that until the appointment of a successor agent shall become effective, neither Borrower shall be obligated to pay any
fees to the successor agent. 

  
 58 

 13.11 No Other Duties. Except as expressly set forth herein, the Administrative Agent
shall have no duties or responsibilities hereunder in its capacity as such. 
 13.12 The Global Coordinator, the Joint
Bookrunners and the Mandated Lead Arrangers. None of the Global Coordinator, the Joint Bookrunners and the Mandated Lead Arrangers, in its respective capacity as such, shall have any duties or responsibilities, or incur any liability, under this
Agreement or the other Loan Documents. 
 14. INDEMNIFICATION 
 14.1 Initial Expenses. Subject to such limitations as have been separately agreed between Ternium, Hylsa and the Joint Bookrunners, the Borrowers shall reimburse the Administrative Agent in Dollars
on demand for all reasonable and documented expenses (including printing and other reproduction costs, computer, search, filing and recording fees, travel and communication costs, due diligence expenses, the costs of any advertisement incident to
the transactions contemplated herein and the reasonable and documented fees and expenses of special Mexico and special New York counsel to the Administrative Agent) incurred by the Administrative Agent and the Joint Bookrunners in connection with
the negotiation, preparation and execution of the Loan Documents, the syndication of the Loans and Loan Commitments and the preparation of any information memorandum relating hereto. Notwithstanding any provision to the contrary contained in this
Agreement, no expenses shall be paid or reimbursed to (i) the Administrative Agent if the Transactions are not consummated as a result of the gross negligence or willful misconduct of, or a breach of this Agreement or the Ternium Loan Agreement
by, the Administrative Agent or the Joint Bookrunners (or any of their Affiliates) or (ii) any Bank if the Transactions are not consummated as a result of the gross negligence or willful misconduct of, or a breach of this Agreement or the
Ternium Loan Agreement by, such Bank (or any of its Affiliates). 
 14.2 Amendment and Enforcement Expenses. The
Borrowers shall reimburse the Administrative Agent and each Bank in Dollars within fifteen days of written demand to that effect for all reasonable expenses incurred as a consequence of, or in connection with, (a) the negotiation, preparation
or execution of any amendment to or waiver under this Agreement for whatever reason (including any change of law or change of circumstance) other than an amendment resulting solely from causes attributable to the Administrative Agent or the Banks,
(b) any Event of Default or (c) the preservation or enforcement of any right of the Administrative Agent or any Bank under the Loan Documents as regards the Borrowers. 

  
 59 

 14.3 Other Expenses. If either Borrower (a) fails, after giving any notice
referred to in Section 2.2, to fulfill the conditions set forth in Article 7 at or before the respective times specified for their fulfillment or otherwise defaults in its irrevocable commitment pursuant to Section 2.2 or (b) fails to
pay any amount payable hereunder as and when due, such Borrower shall reimburse each Bank in Dollars on demand for all reasonable losses (other than loss of anticipated profits or margin) arising from the reemployment of funds obtained, or the
termination, liquidation or redeployment of deposits received, from third parties. For the purpose of calculating losses payable to any Bank under this Section 14.3, such Bank shall be deemed to have (a) actually funded its Loans through
the purchase of a deposit bearing interest at LIBOR in an amount equal to the amount of its Loan Commitment and having a maturity comparable to the relevant Interest Period, and (b) reemployed the funds by depositing them at LIBOR for a period
having a maturity comparable to the number of days from (x) the day of such failure through (y) the last day of the relevant Interest Period. Any reimbursement request pursuant to this Section 14.3 shall be accompanied by a
certificate of the relevant Bank setting forth in reasonable detail the basis for calculating such losses and shall be delivered to the applicable Borrower and shall be conclusive and binding for all purposes hereunder, absent manifest error.

 14.4 Increased Costs. The Borrowers shall reimburse each Bank in Dollars upon at least ten Banking Days’ prior
demand for all increased costs incurred and reductions in amounts received or receivable and reductions in the rate of return on capital of such Bank (or, if such costs or reductions are incurred as a result of capital adequacy regulations, without
duplication, the ultimate bank holding company affected by such increased costs of which such Bank is a Subsidiary), as reasonably determined and documented by such Bank, that are attributable to such Bank’s Loans or the performance by such
Bank of its obligations under this Agreement and that occur by reason of the promulgation of any law, regulation or treaty or any change therein or in the application or interpretation thereof since the date of this Agreement, or by reason of
compliance by such Bank (or, if such costs or reductions are incurred as a result of capital adequacy regulations, without duplication, the ultimate bank holding company affected by such increased costs of which such Bank is a Subsidiary) with any
direction, requirement or request (whether or not having the force of law) of any Governmental Authority issued after the date of this Agreement (any such promulgation or change, a “Regulatory Change”), including any such cost or
reduction resulting from (a) the imposition or amendment of any Taxes other than (i) any Taxes, franchise taxes and similar taxes measured by the net income, profits or capital of such Bank or its Lending Branch and imposed by the
jurisdiction in which such Bank’s principal office or Lending Branch is situated, (ii) any Taxes referred to in Section 5.1 or (iii) any United States withholding tax, except such a tax imposed at a rate in excess of the rate in
effect on the date hereof as the result of a change in law (including any change in an applicable tax treaty) or (b) the imposition or amendment of any reserve, contribution, special deposit, capital adequacy or similar requirement against
assets of, liabilities of, deposits with or for the account of, or loans by, such Bank; provided, however, that neither Borrower shall be responsible for (i) such costs incurred or reductions in amounts received or receivable if
the Regulatory Change in respect of any item in clause (b) above is not of a general nature and is such that it affects only a particular bank, (ii) any portion of the costs incurred or reductions in amounts received or receivable that is
not 

  
 60 

 reasonably allocable to such Borrower, (iii) such reimbursement if notice by the relevant Bank is given
to such Borrower more than 90 days after the Regulatory Change occurred, (iv) such reimbursement to the extent that the costs incurred or reductions in amounts received or receivable are derived (x) from a failure of such Bank to comply
with any Regulatory Change, or (y) solely and simultaneously with a change of the Lending Branch or the assignment of any Loan to another lending office of such Bank (except if such change is required by such Borrower) or (v) such
reimbursement to the extent that the costs incurred or reductions in amounts received or receivable are applicable to any assignee in the case of any assignment or transfer by any Bank (other than any assignment or transfer made at the request of
such Borrower) to such assignee if, at the time of such assignment or transfer, such assignee would be entitled to claim compensation (and the relevant assignor Bank was not then so entitled) or if, at the time of such assignment or transfer, any
Regulatory Change applicable to such assignee had been enacted into law but not yet implemented; and provided further that in the event that either Borrower elects to prepay the Loans made by the affected Bank to avoid making payments
under this Section 14.4 such Borrower shall not be responsible for paying any broken funding costs or losses under Section 3.4. Each Bank that may become entitled to compensation under this Section 14.4 will (A) designate a
different Lending Branch if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the reasonable judgment of the Bank, (x) reduce the amount of any payment receivable by such Bank under this
Agreement or the Notes or otherwise be materially disadvantageous to such Bank or (y) result in a combined amount payable by the applicable Borrower under Section 5.1(a) and this Section 14.4 that is higher than the combined
amount that would otherwise have been payable by such Borrower pursuant to such Sections before such Bank became entitled to compensation under this Section 14.4, or (B) assign its Loans, if such assignment will avoid the need for, or
materially reduce the amount of, such compensation and will not, in the reasonable judgment of the Bank, be materially disadvantageous to such Bank, to a designee of such Borrower (which may be an Affiliate of such Borrower, provided that no
such Affiliate shall have any right to vote on any amendment, waiver, action or other matter under or in connection with this Agreement, nor any right to participate in any meetings or deliberations of or receive communications among the Banks with
respect thereto and the consent of any such Affiliate shall not be required for the purpose of Section 15.7), which designee shall be reasonably acceptable to the Administrative Agent, in accordance with Section 11.1, for a purchase price
equal to the outstanding principal amount of such Loans, accrued interest thereon and all other amounts payable to such Bank hereunder or such other amount as such Bank may in its sole discretion agree with such designee (it being understood and
agreed that neither the Administrative Agent nor any Bank shall have any obligation to purchase such Loans). 
 Any demand for payment of any
amounts pursuant to this Section 14.4 shall describe in reasonable detail the event by reason of which the relevant Bank is making any such demand and the date of occurrence of such event. 

Neither Borrower shall be under any obligation to pay any amounts under this Section 14.4 to the extent that: (i) the Regulatory Change had
been promulgated prior to the date hereof; or (ii) such amounts would not have arisen or been imposed had such Bank (x) been registered for tax purposes as a foreign financial institution with the Mexican Ministry of Finance and
Public Credit for purposes of Article 195, Section I (or any successor provision) of the Mexican Income Tax Law (Ley del Impuesto sobre la Renta) and been resident in a jurisdiction with which Mexico has entered into a treaty for
the avoidance of double taxation which is in effect and met the requirements set forth in such treaty for a reduced withholding tax rate, for so long as such requirement remains applicable, or (y) been a Mexican Bank acting through a Mexican or
offshore Lending Branch; or (iii) such amounts have resulted from such Bank (or its Lending Branch) having exceeded a lending or loan allocation limit imposed by any Governmental Authority; or (iv) such amounts are attributable to the
implementation or application of or compliance with the “International Convergence of Capital Measurement and Capital Standards, a Revised Framework, Comprehensive Version” published by the Basel Committee on Banking Supervision in June
2006, known as “Basel II”, substantially in the form existing on the date of this Agreement or any other law or regulation which implements the same. 

  
 61 

 In the event of any assignment or transfer of any rights, obligations or benefits of any Bank in respect of
its Loans, no assignee or transferee of any such rights, obligations or benefits shall be entitled to demand payment of any amounts under this Section 14.4 if (i) at the time of any such assignment or transfer such assignee was entitled to
demand such payment (and the assignor was not then so entitled); or (ii) the Regulatory Change (a) already existed or had been promulgated at the time of any such assignment or transfer, or (b) implements national or international
recommendations or guidelines existing at the time of any such assignment or transfer. 
 14.5 Information. Each Borrower
agrees to indemnify and hold harmless the Administrative Agent, each of its Affiliates, directors, officers and employees to the fullest extent permitted by law, from and against all losses, claims, damages or liabilities (or actions in respect
thereof) arising out of or based upon any misstatement or alleged misstatement of a material fact contained in any information approved by such Borrower for use in the assignment or other transfer of any Loan or Loan Commitment, or any portion
thereof, or any omission or alleged omission to state therein a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, it being understood that neither Borrower shall make
any representation or warranty concerning estimates or projections contained in any information delivered for the above purpose, except that each Borrower represents and warrants that such estimates and projections were made in good faith by the
management of such Borrower on the basis of assumptions believed by such management to be reasonable (it being understood that projections and estimates are subject to significant uncertainties and contingencies, many of which are beyond such
Borrower’s control, and that no assurance can be given that the projections or estimates will be realized). 
 14.6
General Indemnification. Each Borrower agrees to indemnify to the fullest extent permitted by law the Administrative Agent, the Banks and each Affiliate thereof and their respective directors, officers and employees (each such Person,
together with the Administrative Agent and the Banks, an “Indemnified Party”) from and against any and all losses, liabilities, claims or damages (and any related reasonable and documented legal fees and disbursements of counsel and
costs of investigations) to which any Indemnified Party may become subject, insofar as such losses, liabilities, claims or damages arise out of or result from (i) any actual or proposed use by such Borrower of the proceeds of the Loans or
breach by such Borrower of the Loan Documents to which it is a party or (ii) any investigation, litigation, arbitration or other proceeding (including any threatened investigation or proceeding), whether or not such Borrower and/or any
Indemnified Party is a party thereto, relating to the foregoing, and such Borrower shall reimburse such Indemnified Party upon demand for any reasonable and documented expenses (including any legal fees and fees of engineers, environmental
consultants and similar technical personnel) incurred in connection with any such investigation or proceeding (but excluding any such losses, liabilities, claims, damages or expenses found in a final non-appealable judgment of a court of competent
jurisdiction to have resulted primarily from such Indemnified Party’s breach in bad faith of its obligations hereunder or from the gross negligence or willful misconduct of such Indemnified Party). Each Indemnified Party will give the
applicable Borrower reasonably prompt notice of the commencement of any action or proceeding as to which it is entitled to indemnification hereunder; provided, however, that the failure of any Indemnified Party to give any such notice
shall not relieve such Borrower from its obligations hereunder, except to the extent that such Borrower has been materially prejudiced by such failure. In no event shall any Indemnified Party be liable for any special, indirect, consequential or
punitive damages in connection with this Agreement, the Notes, the Loans or the use of proceeds thereof.

 15. GENERAL 
 15.1 Choice of Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK. 

15.2 Jurisdiction. (a) Any action or proceeding against any party to this Agreement relating in any way to this Agreement or
any Notes may be brought and enforced in the Federal courts of the United States for the Southern District of New York, the courts of the State of New York sitting in the Borough of Manhattan, New York City, and the courts of the corporate domicile
of each of the parties hereto in respect of actions brought against each such party as a defendant, and each of the parties hereto irrevocably submits to the jurisdiction of each such court in respect of any such action or proceeding. Each Obligor
irrevocably appoint CT Corporation System, which currently maintains an office situated at 111 Eighth Avenue, New York, New York 10011, United States, as its agent to receive service of process or other legal summons for purposes of any such action
or proceeding. So long as any Obligor has any obligation under this Agreement, such Obligor will maintain a duly appointed agent in New York City for the service of such process or summons, and if such Obligor fails to maintain such an agent, any
such process or summons may be served by mailing a copy thereof by registered mail, or a form of mail substantially equivalent thereto, addressed to such Obligor at its address as provided for notices hereunder. Nothing in this Section 15.2
shall affect the right of a Bank or the Administrative Agent to serve legal process in any other manner permitted by applicable law. 
 (b) Each Obligor irrevocably waives to the fullest extent permitted by law all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, attachment (both before and after judgment)
and execution to which it might otherwise be entitled in any action or proceeding relating in any way to this Agreement or any Notes in the courts of Mexico, of the United States, of the State of New York or of any other country or jurisdiction, and
no Obligor will raise or claim or cause to be pleaded any such immunity at or in respect of any such action or proceeding. 

  
 63 

 (c) Each of the parties hereto irrevocably waives, to the fullest extent permitted by
applicable law, any objection that it may now or hereafter have to the laying of venue of any such action or proceeding in the United States District Court for the Southern District of New York, or the Supreme Court of the State of New York, County
of New York and any claim that any such action or proceeding brought in any such court has been brought in an inconvenient forum, and each party hereto waives any jurisdiction rights it may have by virtue of its present or any other future domicile,
or otherwise. 
 (d) EACH OF THE OBLIGORS, THE ADMINISTRATIVE AGENT AND THE BANKS IRREVOCABLY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY NOW OR HEREAFTER HAVE TO A TRIAL BY JURY IN RESPECT OF THE LOAN DOCUMENTS. 
 15.3
Loan Currency. (a) If any expense or other amount required to be reimbursed pursuant to this Agreement is originally incurred in a currency other than Dollars, the applicable Borrower shall nonetheless make reimbursement of such expense
or other amount in Dollars, in an amount equal to the amount in Dollars that would have been required for the Person that incurred such expense or other amount to have purchased, in accordance with normal banking procedures, the sum paid in such
other currency (after any reasonable and duly documented premium and costs of exchange) on the day such expense or other amount was originally incurred. Any interest accruing thereon pursuant to Section 4.2 shall be computed on the basis of
such amount in Dollars. 
 (b) If, for the purposes of obtaining judgment in any court, it is necessary to convert a sum due
hereunder or under the Notes in U.S. Dollars into another currency, the parties hereto agree, to the fullest extent they may effectively do so, that the rate of exchange used shall be that at which, in accordance with normal banking procedures, the
Administrative Agent could purchase U.S. Dollars with such other currency in New York City on the Banking Day preceding that on which final, non-appealable judgment is given. 
 (c) Each reference in this Agreement to Dollars is of the essence. The obligation of each Borrower in respect of any amount due under the Loan Documents to which it is a party shall, notwithstanding any
payment in any other currency (whether pursuant to a judgment or otherwise), be discharged only to the extent of the amount in Dollars that the Person entitled to receive such payment may, in accordance with normal banking procedures, purchase with
the sum paid in such other currency (after any premium and costs of exchange) on the Banking Day immediately following the day on which such Person receives such payment. If the amount in Dollars that may be so purchased for any reason falls short
of the amount originally due, the applicable Borrower shall pay such additional amounts, in Dollars, as may be necessary to compensate for such shortfall. Any obligation of either Borrower not discharged by such payment shall be due as a separate
and independent obligation and, until discharged as provided herein, shall continue in full force and effect. 
 15.4
Notes. (a) Each Borrower’s obligations to pay the principal of, and interest on, each installment of each Loan made by each Bank to such Borrower shall be evidenced by a Note. Each Note shall (i) evidence the aggregate
principal of, and interest on, a single installment of each Loan made by the relevant Bank, (ii) bear interest at the default rate as specified in Section 4.2, and (iii) be held in Mexico by the Custodian on behalf of the relevant
Bank. The Custodian shall be appointed by the Banks, the Administrative Agent and the Borrowers pursuant to a separate agreement governed by the laws of the State of New York and setting forth the terms and conditions of such appointment (the
“Custodian Agreement”). 

  
 64 

 (b) The Custodian shall (i) at the request of any Bank through the Administrative Agent
made on or after 5:00 p.m. (Mexico City time) on each Loan Payment Date or the fifth day after each Interest Payment Date on which either Borrower does not pay in full to the Administrative Agent, for the account of such Bank, the aggregate
principal of or interest on the installment of the Loans of such Bank which is due on such Loan Payment Date or such Interest Payment Date, as applicable, deliver to such Bank its Note or Notes issued in respect of such installment and give notice
to the Administrative Agent and the applicable Borrower of such delivery, (ii) upon the acceleration of the Loans in accordance with Section 10.2, at the request of any Bank through the Administrative Agent but only after written notice by
the Administrative Agent to the Custodian (with a copy to the Borrowers) to the effect that such acceleration of the Loans has occurred, deliver to such Bank all of its Notes and give notice to the Administrative Agent and the Borrowers of such
delivery, and (iii) exchange Notes as provided in Section 4.5 hereof; provided that, if (x) the Margin set forth in any Principal Note or Principal Notes required to be delivered to one or more Banks pursuant to clause (i)
or (ii) above is different from the Margin in effect at the time such Principal Note or Principal Notes are required to be delivered to such Bank or Banks and (y) the applicable Borrower notifies the Administrative Agent of such
Borrower’s intent to replace such Principal Note or Principal Notes as provided in clause (B) below, any such notice to be promptly remitted to the Custodian by the Administrative Agent, then (A) the Custodian shall not deliver such
Principal Note or Principal Notes to the applicable Bank or Banks prior to the expiration of the applicable period provided for in clause (B) below, (B) the applicable Borrower may, not later than the close of business, Mexico City
time, on the third Banking Day after the applicable Loan Payment Date, the third Banking Day after the fifth day after the applicable Interest Payment Date or the third Banking Day after the date of receipt of any notice of acceleration, as
applicable, execute and deliver to the Custodian, in replacement for each such Principal Note, a new Principal Note dated the date of issuance of such new Principal Note (with the applicable signatures por aval) reflecting the Margin in
effect at such time and otherwise substantially identical to the replaced Principal Note, and a new Default-Interest Note dated the date of issuance of such new Default-Interest Note (with the applicable signatures por aval) evidencing any
accrued and unpaid interest on the principal amount of the Loans evidenced by the replaced Principal Note, and (C) the Custodian shall either (1) if the applicable Borrower fails to deliver any such new Note or Notes within the applicable
period provided for in clause (B) above, immediately upon the expiration of such period deliver the applicable non-replaced Principal Note or Principal Notes to the applicable Bank or Banks and/or (2) if the applicable Borrower delivers
any such new Note or Notes within the applicable period provided for in clause (B) above, immediately upon receipt thereof deliver to the applicable Bank or Banks such new Note or Notes and promptly cancel and return to the applicable Borrower
the applicable replaced Principal Note or Principal Notes. Notwithstanding the fact that each Note shall be payable on demand, no Bank shall exercise such demand right unless and until the principal or interest evidenced by such Note shall have
become due and payable (as a result of failure to pay the amounts due under such Note or as a result of acceleration) in accordance with the terms of this Agreement. 

  
 65 

 (c) Promptly upon (i) the payment in full of all amounts due to any Bank under a Note
issued for the account of such Bank, the Custodian shall, upon request by the applicable Borrower to the Administrative Agent and the Custodian and confirmation by the Administrative Agent to the Custodian that all relevant amounts have been paid,
promptly cancel and return such Note to such Borrower; (ii) the partial prepayment by either Borrower pursuant to Section 3.2 or 3.3 of any amount due to any Bank under a Note issued for the account of such Bank, the Custodian shall, upon
request by such Borrower to the Administrative Agent and the Custodian and confirmation by the Administrative Agent to the Custodian that all relevant amounts have been paid, cancel and return such Note to such Borrower in simultaneous exchange for
a replacement Note which will be a new Principal Note executed and delivered by such Borrower to the Custodian for the account of such Bank in an amount equal to the amount of principal that remains due to such Bank after giving effect to such
prepayment and evidencing interest thereon; and (iii) the payment in full of any installment of principal or interest on any Loan Payment Date or any Interest Payment Date occurring after the first Loan Payment Date, as the case may be, the
Administrative Agent shall, promptly at the request of the applicable Borrower, confirm its receipt of such payment for the account of the Banks to such Borrower in substantially the form of Exhibit J. In addition, (x) on the IMSA Assumption
Date, the Custodian shall, upon confirmation by the Administrative Agent that the IMSA Assumption Date has occurred, cancel and return to Hylsa each Note theretofore issued by Hylsa in simultaneous exchange for replacement Notes for each Bank which

new Accrued-Interest Note dated the IMSA Assumption Date executed and delivered by IMSA (with the signature por aval of both Hylsa and IMSA Acero) to the Custodian for the account of each Bank evidencing accrued and unpaid interest on the
IMSA Tranche A Loans evidenced by each of the replaced Principal Notes and (D) (1) a new Principal Note dated the IMSA Assumption Date executed and delivered by IMSA (with the signature por aval of both Hylsa and IMSA Acero) to

same principal amount.

provisions hereunder waived, only by an instrument in writing executed by the Borrowers and the Required Banks; provided, however, that no such instrument shall (a) increase the Loan Commitment of any Bank (it being understood
that a waiver of any Default or Event of Default shall not constitute an increase of any Loan Commitment) or extend the expiry date thereof or otherwise subject any Bank to any additional obligation hereunder without the written consent of such

provided that financial statements delivered pursuant to Section 9.06 may be delivered in the language in which they are prepared. 
 15.14 Integration of Terms; Effectiveness; Joinder of Parties. The Loan Documents contain the entire agreement of the parties relating to the subject matter hereof and supersede all oral statements

of the confidential nature of such information and request confidential treatment of such information; provided that, in the case of any disclosure pursuant to clause (2), (3) or (4) above, such Bank or the Administrative
Agent, as the case may be, will give the applicable Borrower prior notice of the information to be disclosed to the extent that such notice is permissible and practicable under the circumstances and, upon the request of such Borrower, will seek to
obtain confidential treatment of such information by the Persons to whom it is disclosed; and provided further that, in the case of any disclosure made to any bank examiners pursuant to clause (B) immediately above, such Bank or the
Administrative Agent, as the case may be, shall not be required to give either Borrower notice thereof unless the circumstances so allow such Bank or the Administrative Agent, as the case may be. 

(b) Each Bank and the Administrative Agent (i) represents and warrants to each Borrower that each of its Representatives that
has received Confidential Information is apprised of his or her obligations concerning the confidentiality of the Confidential Information and (ii) undertakes that each of its Representatives who is provided with Confidential Information will

 (c) Each Bank and the Administrative Agent hereby expressly
(i) acknowledges that it is aware (and undertakes to advise its Representatives who are apprised of the matters that are subject to this Section 15.15) that Ternium has outstanding publicly-held securities in the United States of America,
and that applicable securities laws prevent any person in possession of non-public information about a company from purchasing or selling securities of such company, and from communicating such information to any other person under circumstances in
which it is reasonably foreseeable that such person may purchase or sell such securities, and (ii) agrees not to use, and to take all actions necessary to cause that none of its Representatives use, any Confidential Information in contravention
of any applicable securities laws. 
 (d) This Section 15.15 supersedes the terms and conditions of any confidentiality
agreements entered into before the date hereof to the extent relating to Confidential Information furnished exclusively in connection with the transactions contemplated hereby and/or the syndication of the facility hereunder; provided,
however, that (i) the foregoing shall not affect the survival of any such terms and conditions with respect to any confidential information furnished by either Borrower prior to the date of this Agreement to the extent relating to any other
transaction or matter contemplated by such confidentiality agreement or that is not otherwise expressly contemplated hereby and (ii) in the event of any conflict between the provisions of this Section 15.15 and the terms and conditions of
any such confidentiality agreement with respect to the transactions contemplated hereby and/or the syndication of the facility hereunder, the former shall prevail over the latter.

be promptly paid in full when due (whether at extended maturity, by acceleration or otherwise) in accordance with the terms of such extension or renewal. IMSA Acero’s obligations under this Article 16 constitute a guarantee of payment and
not merely of collection. 
 16.2 Obligations Unconditional. The obligations of each Guarantor under Section 16.1
are absolute, unconditional and irrevocable, irrespective of the value, genuineness, validity, regularity or enforceability of the obligations of the other Guarantors under this Agreement, any other Loan Document or any other agreement or instrument
referred to herein or therein, and, to the fullest extent permitted by applicable law, irrespective of any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor, it being the
intent of this Article 16 that the obligations of each Guarantor hereunder shall be absolute and unconditional under any and all circumstances. Without limiting the generality of the foregoing, it is agreed that the occurrence of any one or
more of the following shall not alter or impair the liability of any Guarantor hereunder, which shall remain absolute and unconditional as described above: 
 (i) at any time or from time to time, without notice to the applicable Guarantor, the time for any performance of or compliance with any of the applicable Guaranteed Obligations shall be extended, or such
performance or compliance shall be waived; 
 (ii) any of the acts mentioned in any of the provisions of this
Agreement, any other Loan Document or any other agreement or instrument referred to herein shall be done or omitted; 

  
 73 

 (iii) the maturity of any of the applicable Guaranteed Obligations shall be
accelerated, or any of the applicable Guaranteed Obligations shall be modified, supplemented or amended in any respect, or any right under this Agreement or any other agreement or instrument referred to herein shall be waived; 

(iv) any moratorium or other similar action is declared by Mexico or any Governmental Authority therein affecting the
obligations of the applicable Guarantor to effect payment hereunder or to perform its other material obligations hereunder; or 
 (v) it becomes unlawful for any other Guarantor to perform or comply with any one or more of its material obligations under this Agreement or any other Loan Document to which it is a party as a
result of any law, regulation or decree being promulgated by any Governmental Authority or any of such other Guarantor’s obligations under this Agreement or any other Loan Document to which it is a party shall cease to be valid, binding or
enforceable (or such other Guarantor shall so assert in writing) or such other Guarantor shall deny or disaffirm any of its obligations thereunder. 
 Each Guarantor hereby expressly waives diligence, presentment, demand of payment, protest and all notices whatsoever, and any requirement that the Administrative Agent or any Bank exhaust any right, power
or remedy or proceed against any other Guarantor under this Agreement, any other Loan Document or any other agreement or instrument referred to herein or therein. 
 16.3 Reinstatement. The obligations of each Guarantor under this Article shall be automatically reinstated if and to the extent that for any reason any payment by or on behalf of any other
Guarantor in respect of the applicable Guaranteed Obligations is rescinded or must be otherwise restored by any holder of any of the applicable Guaranteed Obligations, whether as a result of any proceedings in bankruptcy or reorganization or
otherwise, and each Guarantor agrees that it will indemnify the Administrative Agent and each Bank on demand for all reasonable costs and expenses (including fees of counsel) incurred by the Administrative Agent or such Bank in connection with such
rescission or restoration, including any such costs and expenses incurred in defending against any claim alleging that such payment constituted a preference, fraudulent transfer or similar payment under any bankruptcy, insolvency or similar law.

 16.4 Subrogation. Each Guarantor hereby agrees that until the payment and satisfaction in full of all the applicable
Guaranteed Obligations and the expiration and termination of the Loan Commitments of the Banks under this Agreement it shall not exercise any right or remedy arising by reason of any performance by it of its guarantee in Section 16.1, whether
by subrogation or otherwise, against any of the other Guarantors. 
 16.5 Acceleration. Each Guarantor agrees that, as
between such Guarantor and the Banks, the obligations of each Borrower under this Agreement may be declared to be forthwith due and payable as provided in Section 10.2 (and shall be deemed to have become automatically due and payable in the
circumstances provided in Section 10.2) for purposes of Section 16.1 notwithstanding any stay, injunction or other prohibition preventing such declaration (or such obligations from becoming automatically due and payable) as against the
applicable Borrower and that, in the event of such declaration (or such obligations being deemed 
 to have become automatically due and
payable), such obligations (whether or not due and payable by the applicable Borrower) shall forthwith become due and payable by such Guarantor for purposes of Section 16.1. 

  
 74 

 16.6 Instrument for the Payment of Money. Each Guarantor hereby acknowledges that the
guarantee in this Article 16 constitutes an instrument for the payment of money, and consents and agrees that any Bank or the Administrative Agent, at its sole option, in the event of a dispute by such Guarantor in the payment of any moneys due
hereunder, shall have the right to bring motion-action under New York CPLR Section 3213. 
 16.7 Continuing
Guarantee. The guarantee in this Article 16 is a continuing guarantee, and shall apply to all Guaranteed Obligations whenever arising.

 AMENDMENT No. 1 

AMENDMENT NO.1 dated as of July 18, 2007 between HYLSA, S.A. DE C.V. (the “Borrower”), the Banks executing this Amendment
No.1 on the signature pages hereto and CALYON NEW YORK BRANCH, in its capacity as Administrative Agent under the Loan Agreement referred to below. 
 The Borrower, the banks party thereto (including the Banks executing this Amendment No.1 on the signature pages hereto), and Calyon New York Branch, as Administrative Agent, are parties to a Loan
Agreement dated as of July 12, 2007 (as modified and supplemented and in effect from time to time, the “Loan Agreement”), providing, subject to the terms and conditions thereof, for extensions of credit (by means of loans) to be made
by said banks to the Borrower in an aggregate principal amount up to U.S.$3,750,000,000. 
 The Borrower and the Banks party
hereto wish now to amend the Loan Agreement in certain respects, and accordingly, the parties hereto hereby agree as follows: 

Section 1. Definitions. Except as otherwise defined in this Amendment No.1, terms defined in the Loan Agreement are used herein as
defined therein. 
 Section 2. Amendments. Subject to the satisfaction of the conditions precedent specified in
Section 4 below, but effective as of the date hereof, the Loan Agreement shall be amended as follows: 
 2.01. References
Generally. References in the Loan Agreement (including references to the Loan Agreement as amended hereby) to “this Agreement” (and indirect references such as “hereunder”, “hereby”, “herein” and
“hereof’) shall be deemed to be references to the Loan Agreement as amended hereby. 
 2.02. Definitions.
Section 1.01 of the Loan Agreement shall be amended by amending the following definitions: 

“Assignment Agreement” means each assignment and assumption agreement, substantially in the form set forth in
Exhibit C, or any other form approved by the applicable Borrower and the Administrative Agent, entered into pursuant to Section 11.1 between the Assignor or Assignors and the Purchasing Bank or Purchasing Banks named therein. 

“Interest Period” means, with respect to any Advance, the period commencing on the Disbursement Date for such
Advance (in the case of the initial Interest Period) or on the last day of the next preceding Interest Period for such Advance (in the case of any subsequent Interest Period) and, subject to Section 6.1(b), ending on the day numerically
corresponding to the Disbursement Date for such Advance or such last day (as the case may be) in the next, third or sixth month, as the applicable Borrower may select by notice provided under Section 4.4, following such Disbursement Date or
such last day; provided, however, that (i) any Interest Period that would otherwise extend beyond a Loan Payment Date shall end on such Loan Payment Date, (ii) in the case of any Advance that is made to either Borrower during an
outstanding Interest Period for any Advance theretofore made to such Borrower (except on the last day of such Interest Period), the initial Interest Period for such Advance shall end on the last day of such outstanding Interest Period and
(iii) in the case of any Advance that is made to either Borrower prior to the Transaction Closing Date, the initial Interest Period for such Advance shall end on the Transaction Closing Date. 

 “LIBOR”, with respect to any Interest Period, means the British
Bankers Association (“BBA”) Interest Settlement Rate for U.S. Dollar LIBOR for the period corresponding to such Interest Period as displayed on Reuters -page LIBOR 1 as of 11:00 a.m. London time on the second London Banking Day next
preceding the commencement of such Interest Period. If for any reason LIBOR cannot be determined by reference to the Reuters -page LIBOR 1 or such other page as may replace page LIBOR 1 on that service or such other service as may be nominated by
the BBA as the information vendor for the purpose of displaying BBA Interest Settlement Rates for U.S. Dollars, the Administrative Agent shall determine LIBOR for the relevant Interest Period using the arithmetic average (rounded upward, if
necessary, to the nearest 1116 of 1%) of such offered rates quoted by the Reference Banks. In the case of any Interest Period that is shorter than seven days (other than the initial Interest Period for any Advance) and in respect of which LIBOR
cannot be determined as provided in this definition, LIBOR for such Interest Period shall be calculated as provided above in this definition as if such Interest Period had a duration of seven days. 

“Transaction Closing Date Loans” means, collectively, (a) Hylsa Loans constituting General Advances the
proceeds of which are to be used to (i) purchase, subscribe or otherwise acquire all or a portion of the Optionally Convertible Debt, pay taxes imposed as a condition to, or consequent of, on in connection with, the IMSA Transaction,
(iii) pay fees and expenses and other obligations arising out of or in connection with the IMSA Transaction, including in respect of stock options, stock awards, deferred compensation benefits, severance payments, retention and transaction
bonuses and other similar obligations, and/or (iv) pay interest with respect to the initial Interest Period for any Advance that is made prior to the Transaction Closing Date, and constituting Fiduciary Trust Advances and (b) the IMSA
Loans. 
 2.03. Interest Period Notice. Section 4.4 of the Loan Agreement is hereby amended by adding the following
sentence at the end thereof: 
 “Notwithstanding anything herein to the contrary, except as contemplated in
clause (ii) of the proviso to the definition of the term ‘Interest Period’, with respect to the Advances made to each Borrower there shall be only one Interest Period outstanding at any time.” 

2.04. Use of Proceeds. Section 9.1 of the Loan Agreement is hereby amended by adding the following sentence at the end thereof:

 “9.1 Use of Proceeds. The Borrowers shall use the proceeds of the Loans
(a) in the case of the Hylsa Loans, (i) in an aggregate principal amount up to U .S.$1,800,000,000, solely to (x) purchase, subscribe or otherwise acquire all or a portion of the Convertible Debt and/or (y) fund, directly or
indirectly, the Fiduciary Trust, (ii) in an aggregate principal amount up to U.S.$200,000,000, solely to effect the Hylsa Debt Refinancing and (iii) in an aggregate principal amount up to U.S.$400,000,000, solely to (x) pay taxes
imposed as a condition to, or consequence of, or in connection with, the IMSA Transaction, (y) pay fees and expenses related to the IMSA Transaction and/or pay interest with respect to the initial Interest Period for any Advance that is made
prior to the Transaction Closing Date and/or (z) pay other obligations arising out of or in connection with the IMSA Transaction, including in respect of stock options, stock awards, deferred compensation benefits, severance payments, retention
and transaction bonuses and other similar obligations and (b) in the case of the IMSA Loans, solely to (i) effect the IMSA Bank Debt Refinancing and the IMSA Public Debt Refinancing and/or (ii) pay fees and expenses related to the
IMSA Bank Debt Refinancing and the IMSA Public Debt Refinancing. No part of the proceeds from the Loans will be used in violation of Section 7 of the Securities Exchange Act of 1934, as amended (or any regulations issued pursuant thereto,
including Regulations T, U and X of the Board of Governors of the Federal Reserve System, 12 C.F.R., Chapter II, as amended). Margin Stock shall not at any time constitute more than 25% of the value of the consolidated assets of the Borrowers and
their Subsidiaries. “ 
 2.05. Notice of Borrowing. Exhibit B to the Loan Agreement shall be amended by adding the
following words at the end of clause (3) thereof, immediately prior to the period: 
 “[shall end on
[—]”. 
 Section 3. Representations and Warranties. The Borrower represents and warrants to the Banks and the
Administrative Agent that (a) the representations and warranties of the Borrower set forth in Section 8.1 of the Loan Agreement (except the representations and warranties set forth in Section 8.1 (1) to the extent there has been
a change in applicable law or regulation or in the interpretation thereof since the date of this Agreement), and the representations and warranties of the Borrower made pursuant to the other Loan Documents to which the Borrower is a party are true
and correct on the date hereof as if made on and as of the date hereof (or, if any such representation or warranty is expressly stated to have been made as of a specific date, such representation or warranty shall be true and correct as of such
specific date), and as if each reference in said Section 8.1 to “this Agreement” included reference to this Amendment No.1 and (b) no Default or Event of Default has occurred and is continuing. 

Section 4. Condition Precedent. The amendments set forth in Section 2 hereof shall become effective, as of the date hereof,
upon receipt by the Administrative Agent of counterparts of this Amendment No.1 executed by the Borrower and Banks party to the Loan Agreement constituting the Required Banks. 

 Section 5. Miscellaneous. Except as herein provided, the Loan Agreement shall remain
unchanged and in full force and effect. This Amendment No. 1 may be executed in any number of counterparts, all of which taken together shall constitute one and the same amendatory instrument and any of the parties hereto may execute this
Amendment No. 1 by signing any such counterpart. This Amendment No. 1 shall be governed by, and construed in accordance with, the law of the State of New York.

To: Calyon New York Branch as Administrative Agent 
     under, and the Banks from time to time parties to the 

    Loan Agreement referred to below. 
 Re.: Consent 
 Ladies and Gentlemen: 

We make reference to the Loan Agreement, dated as of July 12, 2007 (as amended by Amendment No. 1 dated as of July 18,
2007, the “Loan Agreement”), among Hylsa, S.A. de C.V. (“Hylsa”), Grupo IMSA, S.A.B. de C.V. (“IMSA” and together with Hylsa, the “Borrowers”), IMSA Acero, S.A. de C.V.
(“Imsa Acero”), the Banks parties thereto and Calyon New York Branch, as Administrative Agent, providing for loans to the Borrowers in an aggregate principal amount of up to U.S.$3,750,000,000. All terms defined in the Agreement and
used but not otherwise defined herein have the meanings given to them in the Loan Agreement. 
 A. WHEREAS, each of the
Borrowers and Imsa Acero are direct or indirect wholly-owned Subsidiaries of Ternium, and Ternium owns various other direct or indirect Subsidiaries incorporated or organized, as applicable, under the laws of Mexico (collectively, together with the
Borrowers and Imsa Acero, the “Mexican Subsidiaries”) 
 B. WHEREAS, Ternium deems advisable and in the best
interest of its Mexican Subsidiaries to undertake a reorganization in the corporate structure of its Mexican Subsidiaries, by way of the transactions described in Recitals C, D, E, F and G below (all such transactions, the “Corporate
Restructuring”); 
 C. WHEREAS, I.I.I. Industrial Investments Inc. S.A. de C.V. (“I.I.I.”), a Mexican
Subsidiary, has undertaken all corporate actions necessary to merge with and into IMSA, in a transaction expected to become effective in the near future, in which IMSA would be the surviving corporation and would be renamed as Ternium Mexico S.A. de
C.V. (“Ternium Mexico”) and I.I.I. would cease to exist as a separate entity (the “I.I.I.-Ternium Merger”). As a result of the I.I.I.-Ternium Merger, Ternium Mexico would hold 100% of the share capital of Imsa Acero
and 70% of the share capital of Hylsamex S.A. de C.V. (“Hylsamex”), which will in turn hold 100% of the share capital of Hylsa; 
 D. WHEREAS, Hylsa intends to spin-off and transfer all of its assets and liabilities (including its rights and obligations under the Loan Agreement) to a newly created corporation, to be named Hylsa
Industrias, S.A. de C.V. (“Hylsa Industrias”), with Hylsa retaining all of its current employees and related obligations (the “Hylsa Spin-Off”); 

E. WHEREAS, substantially simultaneously with the consummation of the Hylsa Spin-Off, Hylsa Industrias (as successor to Hylsa under the
Loan Agreement as a result of the Hylsa Spin-Off) intends to merge with and into Ternium Mexico (as successor of IMSA under the Loan Agreement as a result of IMSA being renamed Ternium Mexico), in a transaction in which Ternium Mexico would be the
surviving corporation and Hylsa Industrias would cease to exist as a separate entity (the “Hylsa Industrias-Ternium Merger”). After consummation of the Hylsa Industrias-Ternium Merger, Ternium Mexico would hold 100% of the share
capital of Imsa Acero and 100% of the share capital of Hylsa; 

 F. WHEREAS, substantially simultaneously with the consummation of the Hylsa Spin-Off and the
Hylsa Industrias-Ternium Merger, Hylsamex intends to merge with and into Ternium Mexico, in a transaction in which Ternium Mexico would be the surviving corporation and Hylsamex would cease to exist as a separate entity (the
“Hylsamex-Ternium Merger”). After consummation of the Hylsamex-Ternium Merger, Ternium Mexico would hold 100% of the share capital of Imsa Acero and 100% of the share capital of Hylsa; 

G. WHEREAS, Imsa Acero and its Subsidiary Industrias Monterrey, S.A. de C.V., a Mexican Subsidiary, intend to merge with and into Ternium
Mexico, in a transaction in which Ternium Mexico would be the surviving corporation and Imsa Acero and Industrias Monterrey would cease to exist as separate entities (the “IMSA Acero-Ternium Merger”). After consummation of the IMSA
Acero-Ternium Merger, Ternium Mexico would hold 100% of the share capital of Hylsa; 
 H. WHEREAS, the consummation of the Hylsa
Spin-Off and the Hylsa Assignment (as defined below) requires the consent of each of the Banks as a consequence of certain provisions of the Loan Agreement; 
 I. WHEREAS, under Sections 15.7 and 15.8 of the Loan Agreement, this Consent shall be entered into in writing by the Borrowers, the Administrative Agent and each of the Banks; and 

J. WHEREAS, the banks and other financial institutions parties to this Consent constitute all of the Banks parties to the Loan Agreement
as of the date of Effectiveness Date (as defined below). 
 NOW, THEREFORE, it being understood that certain of the transactions
contemplated by the Corporate Restructuring are permitted under the Loan Agreement and the other Loan Documents, the Borrowers, the Administrative Agent and the Banks hereby agree as follows: 

SECTION 1. Consent and Agreement 
 1.1 Notwithstanding any provision to the contrary in the Loan Agreement, or in any other Loan Document, the Administrative Agent and the Banks hereby consent to the I.I.I.-Ternium Merger, the Hylsa
Spin-Off (subject to Section 1.2. below), the Hylsa Industrias-Ternium Merger (subject to Section 1.3 below), the Hylsamex-Ternium Merger and the IMSA Acero-Ternium Merger. 

1.2 Without limiting the generality of the foregoing, the Administrative Agent and the Banks hereby consent to the Hylsa Spin-Off so
that, at any time after the date hereof, Hylsa may transfer any of its assets and liabilities to Hylsa Industrias pursuant to the Hylsa Spin-Off and may assign to Hylsa Industrias, and Hylsa Industrias may assume from Hylsa, all of Hylsa’s
rights and obligations, as Borrower and Guarantor, under the Loan Agreement and all other Loan Documents (the “Hylsa Assignment”), by executing an assignment and assumption agreement in the form attached as Exhibit A hereto, and
each of the Banks hereby consents to the execution by the Administrative Agent on such Bank’s behalf of such an assignment and assumption agreement, provided that, (i) the Hylsa Spin-Off is consummated substantially simultaneously
with the consummation of the Hylsa Assignment, or (ii) if any transfer of assets and liabilities by Hylsa to Hylsa Industrias pursuant to the Hylsa Spin-Off (an “Asset Transfer”) is not effected substantially simultaneously
with the consummation of the Hylsa Assignment, Hylsa Industrias shall, prior to or simultaneously with the occurrence of such Asset Transfer, sign por aval each of the Notes theretofore issued by Hylsa and at such time held by the Custodian.
For purposes of this Section two transactions shall be deemed to have been consummated “substantially simultaneously” if the last to occur of such transactions is consummated no later than on the Business Day next succeeding the day on
which the first to occur of such transactions has been consummated. 

 1.3 Without limiting the generality of the foregoing, the Administrative Agent and the Banks
hereby agree that (x) the Hylsa Industrias-Ternium Merger shall be deemed to constitute the Transaction Merger contemplated under the Loan Agreement notwithstanding the fact that, after the consummation of the Hylsa Industrias-Ternium Merger,
Hylsa (which shall have ceased to be a Borrower under the Loan Agreement upon consummation of the Hylsa Assignment) and Ternium Mexico (as successor to IMSA) will continue to have a separate legal existence from each other, (y) the date of
effectiveness of the Hylsa Industrias-Ternium Merger shall be deemed to constitute the Transaction Merger Date contemplated under the Loan Agreement, and (z) as a result of the Hylsa Industrias-Ternium Merger, and once effective, Ternium Mexico
will be deemed to be the Surviving Corporation under the Loan Agreement and will assume all of Hylsa Industrias’ rights and obligations under the Loan Agreement and all other Loan Documents, provided, that, prior to, or
concurrently with, the effectiveness of the Hylsa Industrias-Ternium Merger, Sections 9.15(vi) and 15.4(c) of the Loan Agreement shall have been satisfied, it being agreed that Sections 9.15(vi) and 15.4(c) of the Loan Agreement shall be deemed
satisfied when the Administrative Agent shall have received: 
 (a) certified copies of (i) Hylsa’s corporate
resolution approving the Hylsa Spin-Off, (ii) Hylsa Industrias and Ternium Mexico corporate resolutions approving the Hylsa Industrias-Ternium Merger and (iii) the agreement governing the Hylsa Industrias-Ternium Merger, if any.

 (b) an opinion of Ritch Mueller, S.C., special Mexican counsel to Hylsa, substantially in the form set forth in Exhibit B
hereto. 
 (c) an irrevocable written acceptance by CT Corporation System of its appointment as the agent of Ternium Mexico as
the Surviving Corporation to receive service of process (together with a power-of-attorney, duly notarized under Mexican law to that effect substantially in the form set forth in Exhibit C hereto). 

(d) upon confirmation by the Administrative Agent to the Custodian that the Hylsa Industrias-Ternium Merger has occurred, cancel and
return to Ternium Mexico each Note theretofore issued by Hylsa and IMSA in simultaneous exchange for replacement Notes for each Bank which will be (A) (1) a new Principal Note dated the Transaction Merger Date executed and delivered by
Ternium Mexico (with the signature por aval of IMSA Acero, to the extent that the IMSA Acero-Ternium Merger has not then become effective) to the Custodian for the account of each Bank in an amount equal to the amount of principal of the
Tranche A Loans that remains due to such Bank under each of the applicable replaced Principal Notes after the occurrence of the Transaction Merger Date and (2) a new Accrued-Interest Note dated the Transaction Merger Date executed and delivered
by Ternium Mexico (with the signature por aval of IMSA Acero, to the extent that the IMSA Acero-Ternium Merger has not then become effective) to the Custodian for the account of each Bank evidencing accrued and unpaid interest on the Tranche
A Loans evidenced by each of the applicable replaced Principal Notes and (B) (1) a new Principal Note dated the Transaction Merger Date executed and delivered by Ternium Mexico (with the signature por aval of IMSA Acero, to the

 The number of the Registered Shares shall remain unaltered throughout the term of this

such Shareholder’s Registered Shares, or (b) any split (desdobramentos) or grouping (grupamento) of the Registered Shares, shall constitute Registered Shares for all purposes under this Agreement. 

 

	2.2	The Shareholders hereby covenant and agree that, while any of them or their respective Affiliates may from time to time acquire and/or hold Shares not bound by this
Agreement (i.e., Shares other than the Registered Shares), each of them shall vote any and all such Shares owned by it, and cause its Affiliates to vote any and all Shares owned by such Affiliates, in accordance with any decisions adopted by the
Shareholders at a Preparatory Meeting pursuant to Section 4 (Voting). 

 Section 3. Transfer of Shares 

 

	3.1	Except as set forth in this Section 3, a Shareholder may not Transfer, or create, or suffer or permit to exist, any mortgage, pledge, hypothecation, lien, security
interest, assignment by way of security or other encumbrance on, all or any portion of its Registered Shares without the prior written consent of all the other Shareholders. 

 

	3.2	Intra Group Transfers. Any Shareholder belonging to NSC Group, T/T Group or CEU Group may Transfer all or any portion of its Registered Shares to any other
Shareholder belonging to the same Group as such Shareholder; provided that the Transferring Shareholder shall give to the other Shareholders and Usiminas written notice of the intended Transfer no later than five (5) days prior to the
intended Transfer. 

	3.3	Transfers to Affiliates. Without limiting the Shareholders’ rights under Section 3.2, any Shareholder may Transfer all or any portion of its Registered
Shares to any of its Affiliates; provided that (a) the Transferring Shareholder shall give to the other Shareholders and Usiminas written notice of the intended Transfer not later than ten (10) days prior to the intended Transfer
providing for reasonable detail on such Affiliate (including the identity of such Affiliate and reasonable evidence that such Affiliate qualifies as an “Affiliate” (as defined in Section 1.1) of the Transferring Shareholder);
(b) prior to, or simultaneously with the consummation of such Transfer, such Affiliate shall execute a written instrument pursuant to which, effective as of the consummation of such Transfer, such Affiliate shall become a party to this
Agreement and assume all of the rights and obligations of the Transferring Shareholder under this Agreement with respect to the Registered Shares to be Transferred, with such Registered Shares remaining bound by this Agreement; and (c) the
Transferring Shareholder shall remain liable for the performance of such Affiliate’s obligations under this Agreement. 

  

	3.4	Third-Party Transfers; Right of First Refusal. If any Shareholder belonging to NSC Group, T/T Group or CEU Group has the bona fide intention, and receives
a written offer, to Transfer all or any portion of its Registered Shares (the “Section 3.4 Shares”) to a Person other than an Affiliate of such Shareholder or a Shareholder belonging to the same Group as such
Shareholder, then such Transferring Shareholder shall follow the procedures below: 

  

	 	(a)	The Transferring Shareholder shall deliver, as promptly as practicable, and in no event later than five (5) days following the receipt of such offer, a written
notice (the “Section 3.4 Notice”) to the other Shareholders and Usiminas including: 

  

	 	(i)	a representation that such Shareholder intends to accept such offer; 

  

	 	(ii)	the name, address, telephone number and principal business of the proposed Transferee (the “Section 3.4 Transferee”), specifying whether
the Section 3.4 Transferee is engaged, directly or through an Affiliate, in any business in which Usiminas or any of its subsidiaries is engaged; 

  

	 	(iii)	if any Government Authorization is required for the consummation of the Transfer, description of such required Government Authorization and, if the Transferring
Shareholder belongs to CEU Group, the date (as shall be specified in the offer) by which any such Government Authorization must be obtained(the “Section 3.4 Government Authorization Expiration Date”); and

  

	 	(iv)	the number of Section 3.4 Shares to be Transferred and a description of all material terms and conditions on which such Section 3.4 Shares are to be
Transferred, including purchase price, payment terms and conditions, closing conditions, indemnification provisions (including any termination or break-up fees, monetary adjustments, penalties, loss of upfront payments), termination provisions and
post-closing indemnification provisions (if any) (the “Material Original Terms”) as set forth in the written offer to Transfer the Section 3.4 Shares. 

 Usiminas shall, no later than one (1) Business Day upon receipt of the Section 3.4
Notice, inform in writing all Shareholders of the date on which it received the Section 3.4 Notice. 
 Each Shareholder
(other than the Transferring Shareholder) shall have the option (but not the obligation) to purchase (either directly and/or through its Affiliate(s)) the Section 3.4 Shares pursuant to the procedures described below in this Section 3.4 on
the same terms as the Material Original Terms and subject to Section 3.4(f). 
 Within sixty (60) days after receipt of
the Section 3.4 Notice by Usiminas (the “Section 3.4 Period”), each Shareholder (other than the Transferring Shareholder) shall have the option (but not the obligation) to give notice to the other Shareholders and Usiminas
stating such Shareholder’s irrevocable election as to whether or not to purchase (either directly and/or through its Affiliate(s)) either its pro rata portion or all of the Section 3.4 Shares (the “Right of First Refusal
Exercise Notice”), it being understood and agreed that if a Shareholder does not give such notice during the Section 3.4 Period, that Shareholder shall be deemed to have chosen not to purchase any Section 3.4 Shares.

 The applicable “pro rata portion” of each Shareholder shall be calculated as follows: 

 

	 	(i)	for the purpose of Section 3.4(b), it shall be such proportion, expressed in percentage terms, as (x) the number of Registered Shares owned by such
Shareholder bears to (y) the aggregate number of Registered Shares owned by the Group to which such Shareholder belongs, excluding the Registered Shares owned by the Transferring Shareholder; or 

 

	 	(ii)	for the purpose of Section 3.4(c), it shall be such proportion, expressed in percentage terms, as (x) the number of Registered Shares owned by such
Shareholder bears to (y) the aggregate number of Registered Shares owned by all Shareholders, excluding the Registered Shares owned by the Group to which the Transferring Shareholder belongs. 

 

	 	(b)	Shareholders belonging to the same Group as the Transferring Shareholder shall have the first priority to acquire, in accordance with the provisions below, the
Section 3.4 Shares; provided that they acquire all (but not less than all) of the Section 3.4 Shares. Unless otherwise agreed among all Shareholders belonging to the same Group as the Transferring Shareholder that provide a Right of
First Refusal Exercise Notice, the allocation of such Section 3.4 Shares among such Shareholders shall be made in accordance with the following rules: 

 

	 	(i)	If only one Shareholder belonging to the same Group as the Transferring Shareholder provides a Right of First Refusal Exercise Notice and if (x) such Right of
First Refusal Exercise Notice states an election to purchase all of the Section 3.4 Shares, then such Shareholder (or the Affiliate(s) indicated in such Shareholder’s Right of First Refusal Exercise Notice) shall have the obligation to
purchase all of the Section 3.4 Shares on the same terms as the Material Original Terms (subject to Section 3.4(f)) or (y) such Right of First Refusal Exercise Notice states an election to purchase its pro rata portion of the
Section 3.4 Shares, then such Shareholder shall have the option (but not the obligation) to purchase (either directly or through any Affiliate(s)) all of the Section 3.4 Shares on the same terms as the Material Original Terms (subject to
Section 3.4(f)), which option shall be exercised by giving written notice to that effect to the other Shareholders and Usiminas no later than by the expiration of the Section 3.4(b) Purchase Period (as defined below).

	 	(ii)	If two or more Shareholders belonging to the same Group as the Transferring Shareholder provide a Right of First Refusal Exercise Notice, then, and irrespective of
whether they stated an election to purchase their pro rata portion or all of the Section 3.4 Shares, such Shareholders (or the Affiliate(s) indicated in their respective Right of First Refusal Exercise Notices) shall have the obligation to
purchase their corresponding pro rata portions of the Section 3.4 Shares on the same terms as the Material Original Terms (subject to Section 3.4(f)), subject to appropriate adjustments to eliminate any fractional Shares; provided
that no such Shareholder may purchase its pro rata portion of the Section 3.4 Shares unless all such Shareholders purchase, in the aggregate, all (and not less than all) the Section 3.4 Shares. Unless otherwise agreed among such
Shareholders, the allocation of any remaining Section 3.4 Shares among such Shareholders shall be made in accordance with the following rules: 

  

	 	(A)	if only one of such Shareholders shall have stated an election to purchase all of the Section 3.4 Shares, then any remaining Section 3.4 Shares shall be
purchased by such Shareholder (or the Affiliate(s) indicated in its Right of First Refusal Exercise Notice); 

  

	 	(B)	if more than one (but less than all) such Shareholders shall have stated an election to purchase all of the Section 3.4 Shares in the Right of First Refusal
Exercise Notice, then any remaining Section 3.4 Shares shall be purchased by such Shareholders (or the Affiliate(s) indicated in their respective Right of First Refusal Exercise Notices). The number of remaining Section 3.4 Shares to be
purchased by each such Shareholder shall be the number of remaining Section 3.4 Shares which bears the same ratio to the aggregate number of remaining Section 3.4 Shares being purchased as the number of Registered Shares owned by such
Shareholder bears to the aggregate number of Registered Shares owned by all Shareholders belonging to the same Group as the Transferring Shareholder who shall have stated an election to purchase all of the Section 3.4 Shares, subject to
appropriate adjustments to eliminate any fractional Shares; 

	 	(C)	if no such Shareholder shall have stated an election to purchase all of the Section 3.4 Shares, then each such Shareholder shall have the option (but not the
obligation) to purchase (either directly or through any Affiliate(s) indicated in its Right of First Refusal Exercise Notice) any remaining Section 3.4 Shares, which option shall be exercised by giving written notice to that effect to the other
Shareholders and Usiminas no later than by the expiration of the Section 3.4(b) Purchase Period. The number of remaining Section 3.4 Shares to be purchased by each such Shareholder shall be the number of remaining Section 3.4 Shares
which bears the same ratio to the aggregate number of remaining Section 3.4 Shares being purchased as the number of Registered Shares owned by such Shareholder bears to the aggregate number of Registered Shares owned by all Shareholders
belonging to the same Group as the Transferring Shareholder exercising the option provided in this subparagraph (C), subject to appropriate adjustments to eliminate any fractional Shares. 

 

	 	(D)	In the event that any such Shareholder notifies the other such Shareholders, at any time prior to the expiration of the Section 3.4(b) Purchase Period, that it (or
the Affiliate(s) indicated in its Right of First Refusal Exercise Notice) is unable to purchase its pro rata portion of the Section 3.4 Shares and/or any remaining Section 3.4 Shares as per paragraphs (i) or (ii) above (as
applicable), then any other such Shareholder shall have the option (but not the obligation) to purchase (either directly or through any Affiliate(s)) such Section 3.4 Shares, which option shall be exercised by giving written notice to that
effect to the other Shareholders and Usiminas no later than by the expiration of the Section 3.4(b) Purchase Period. The number of such Section 3.4 Shares to be purchased by each such Shareholder shall be the number of such
Section 3.4 Shares which bears the same ratio to the aggregate number of such Section 3.4 Shares being purchased as the number of Registered Shares owned by such Shareholder bears to the aggregate number of Registered Shares owned by all
Shareholders belonging to the same Group as the Transferring Shareholder exercising the option provided in this subparagraph (D), subject to appropriate adjustments to eliminate any fractional Shares. 

Subject to Section 3.4(f), any and all purchases of Section 3.4 Shares pursuant to this Section 3.4(b) must be consummated
within thirty (30) days after the expiration of the Section 3.4 Period (the “Section 3.4(b) Purchase Period”). 

	 	(c)	If (but only if) the Shareholders belonging to the same Group as the Transferring Shareholder fail to exercise their right of first refusal or to consummate the
acquisition of all of the Section 3.4 Shares in accordance with Section 3.4(b), then the Shareholders belonging to the other Groups shall have preference to acquire such Section 3.4 Shares; provided that they acquire all
(and not less than all) of such Section 3.4 Shares. Unless otherwise agreed among all Shareholders belonging to such other Groups that provide a Right of First Refusal Exercise Notice, the allocation of such Section 3.4 Shares among such
Shareholders shall be made in accordance with the same rules provided in paragraphs (i) and (ii) of Section 3.4(b) (it being understood, for the avoidance of doubt, that the option contemplated in subparagraph (D) of paragraph
(ii) of Section 3.4(b) shall apply also in the context of this Section 3.4(c)), which shall be applied mutatis mutandis as if: 

  

	 	(i)	references to “Shareholder(s) belonging to the same Group as the Transferring Shareholder” were references to “Shareholder(s) belonging to any
Group other than the Transferring Shareholder’s Group”; and 

  

	 	(ii)	references to “the expiration of the Section 3.4(b) Purchase Period” were references to “the expiration of the term provided in the last
paragraph of this Section 3.4(c)”. 

 Subject to Section 3.4(f), any and all purchases of
Section 3.4 Shares pursuant to this Section 3.4(c) must be consummated (A) if no Shareholders belonging to the same Group as the Transferring Shareholder shall have exercised their right of first refusal pursuant to
Section 3.4(b), within thirty (30) days after the expiration of the Section 3.4 Period, or (B) if any of such Shareholders shall have exercised its right of first refusal pursuant to Section 3.4(b) but thereafter
failed to consummate the acquisition of all of the Section 3.4 Shares in accordance with Section 3.4(b), within thirty (30) days after the expiration of the Section 3.4(b) Purchase Period. 

 

	 	(d)	If (but only if) the Shareholders belonging to the same Group as the Transferring Shareholder fail to exercise their right of first refusal or to consummate the
acquisition of all of the Section 3.4 Shares in accordance with Section 3.4(b) and the Shareholders belonging to Groups other than the Transferring Shareholder’s Group fail to exercise their right of first refusal or to
consummate the acquisition of all of the Section 3.4 Shares in accordance with Sections 3.4(c), then the Transferring Shareholder may Transfer all (but not less than all) the Section 3.4 Shares to the Section 3.4 Transferee;
provided that: 

  

	 	(i)	Subject to Section 3.4(f), 

  

	 	(A)	if no Shareholder shall have exercised its right of first refusal pursuant to Section 3.4(b) or Section 3.4(c), such Transfer must be consummated within sixty
(60) days after the expiration of the Section 3.4 Period; or  

  

	 	(B)	if any Shareholders shall have exercised their right of first refusal pursuant to Section 3.4(b) but thereafter failed to consummate the acquisition of all of the
Section 3.4 Shares in accordance with Section 3.4(b) and no Shareholder shall have exercised its right of first refusal pursuant to Section 3.4(c), such Transfer must be consummated within thirty (30) days after the
expiration of the Section 3.4(b) Purchase Period, or  

	 	(C)	if any Shareholders shall have exercised their right of first refusal pursuant to Section 3.4(c) but thereafter failed to consummate the acquisition of all of the
Section 3.4 Shares in accordance with Section 3.4(c), such Transfer must be consummated within thirty (30) days after (x) the expiration of the term provided in (A) of the last paragraph of Section 3.4(c) (if no
Shareholder shall have exercised its right of first refusal pursuant to Section 3.4(b)) or (y) the expiration of the term provided in (B) of the last paragraph of Section 3.4(c) (if any Shareholders shall have exercised
their right of first refusal pursuant to Section 3.4(b) but thereafter failed to consummate the acquisition of all of the Section 3.4 Shares in accordance with Section 3.4(b)). 

 

	 	(ii)	such Transfer must be made on the same Material Original Terms set forth in the written offer provided with the Section 3.4 Notice; and 

 

	 	(iii)	prior to, or simultaneously with the consummation of the Transfer of the Section 3.4 Shares to the Section 3.4 Transferee, such Section 3.4 Transferee
must execute a written instrument pursuant to which, effective as of the consummation of such Transfer, such Section 3.4 Transferee shall become a party to this Agreement and assume all of the rights and obligations of the Transferring
Shareholder under this Agreement with respect to the Section 3.4 Shares to be Transferred, with such Section 3.4 Shares remaining bound by this Agreement. 

If the Section 3.4 Shares are not so Transferred within the relevant period set forth in Section 3.4(d)(i), the Transferring
Shareholder shall not be allowed to Transfer the Section 3.4 Shares to the Section 3.4 Transferee unless the Transferring Shareholder once again follows the procedure set forth in this Section 3.4. 

 

	 	(e)	All notices given under this Section 3.4 shall be given concurrently to all Shareholders and Usiminas. 

 

	 	(f)	The Parties agree that, notwithstanding anything to the contrary in this Section 3.4 or in any other provision of this Agreement, in the event that any Government
Authorizations are required as a condition to the consummation of a Transfer of Registered Shares pursuant to this Section 3.4 (including through application of Section 3.5) (a “Conditioned Transfer”), then
the applicable maximum term for consummating such Conditioned Transfer shall be extended by such additional time period as may be strictly necessary to obtain all such Government Authorization, provided that: 

	 	(i)	each Shareholder involved in such Conditioned Transfer (x) promptly takes or causes to be taken all actions, and does or causes to be done all things, necessary,
proper or advisable on its part under applicable Law to obtain all requisite Government Authorizations as soon as reasonably practicable and (y) in good faith keeps the other Shareholders and Usiminas apprised of the status of matters relating
to the obtaining of such Government Authorizations (including giving notice to the other Shareholders and Usiminas promptly upon such Government Authorizations shall have been obtained); and  

 

	 	(ii)	the relevant term for completing such Conditioned Transfer shall automatically and immediately terminate on the earliest to occur of (A) a final, unappealable
denial (whether explicit or implicit, by operation of any applicable Law or otherwise) of any requisite Government Authorization (in which case the Shareholder involved in such Conditioned Transfer shall give prompt notice thereof to all other
Shareholders and Usiminas), or (B) the date that falls eighteen (18) months after the commencement of such term and (C) if the Transferring Shareholder belongs to CEU Group, on the later to occur of (x) the Section 3.4
Government Authorization Expiration Date and (y) seventy-five (75) days after the expiration of the Section 3.4 Period. 

 Usiminas and the Shareholders other than the Shareholder involved in a Conditioned Transfer shall, to the extent reasonably necessary, proper or advisable for the obtaining of any such Government
Authorization required for consummating such Conditioned Transfer, cooperate in good faith and use their reasonable endeavors to facilitate actions taken and things done by the Shareholder involved in the Conditioned Transfer. 

 

	 	(g)	Whenever a Shareholder gives a Right of First Refusal Exercise Notice and, thereafter, fails to consummate any such Transfer within the applicable period to consummate
the acquisition, such Shareholder shall, pursuant to the terms of the relevant share purchase agreement, if any, indemnify the Transferring Shareholder for, and shall pay to the Transferring Shareholder the amount of, any loss, liability, claim,
damage (but excluding incidental and consequential damages), expense (including, without limitation, costs of investigation and defense and reasonable attorney fees) or diminution of value suffered or incurred by the Transferring Shareholder as a
result of such failure. 

  

	3.5	If a Change of Control or Bankruptcy Event occurs with respect to a Shareholder of NSC Group, T/T Group or CEU Group (the “Section 3.5 Defaulting
Shareholder”), unless the Shareholders of NSC Group, T/T Group and CEU Group (other than the Section 3.5 Defaulting Shareholder) (the “Section 3.5 Non-Defaulting
Shareholders”) otherwise agree in writing within thirty (30) days after the date on which all Section 3.5 Non-Defaulting Shareholders have received the Occurrence Notice (as defined in Section 3.7) (or
within thirty (30) days after the date on which all Section 3.5 Non-Defaulting Shareholders have confirmed the occurrence of the Change of Control or Bankruptcy Event, in case the Occurrence Notice is not given to all Section 3.5
Non-Defaulting Shareholders within fifteen (15) days after the occurrence), the provisions of Section 3.4 (other than Section 3.4(d)) shall apply mutatis mutandis as if: 

 

	 	(a)	the Section 3.5 Defaulting Shareholder were “the Transferring Shareholder”; 

	 	(b)	all of the Registered Shares owned by the Section 3.5 Defaulting Shareholder were “the Section 3.4 Shares”; 

 

	 	(c)	the date on which all Section 3.5 Non-Defaulting Shareholders have received the Occurrence Notice (or, in case the Occurrence Notice is not given within fifteen

	 	(d)	the “purchase price” per Registered Share owned by the Section 3.5 Defaulting Shareholder set out in the Section 3.4 Notice were the lower of

trading price differential—in percentage terms—between Usiminas ordinary shares and preferred shares on the BM&FBovespa), and (ii) the previous six-month (6-month) average trading price per Usiminas ordinary shares on the
BM&FBovespa. 

  

	3.6	In the event that a Shareholder’s Affiliate that is not a party to this Agreement purchases any Registered Shares pursuant to Section 3.4 or 3.5,
(a) prior to, or simultaneously with the consummation of such purchase, such Affiliate shall execute a written instrument pursuant to which, effective as of the consummation of such Transfer, such Affiliate shall become a party to this
Agreement and assume all of the rights and obligations of the Transferring Shareholder under this Agreement with respect to the Registered Shares to be Transferred, with such Registered Shares remaining bound by this Agreement and (b) such
Shareholder shall remain liable for the performance of such Affiliate’s obligations under this Agreement. 

  

	3.7	If a Change of Control or Bankruptcy Event occurs with respect to a Shareholder, (a) such Shareholder shall immediately give written notice of the occurrence of
such event (the “Occurrence Notice”) to the other Shareholders and to Usiminas, and (b) until the earlier to occur of (i) the date on which all the Section 3.5 Non-Defaulting Shareholders agree in writing, in
accordance with Section 3.5, that the provisions of Section 3.4 shall not apply and (ii) the date on which the procedures set forth in Section 3.5 for the Transfer of the Section 3.5 Defaulting Shareholder’s Registered
Shares shall have all been completed (and irrespective of whether any Section 3.5 Non-Defaulting Shareholders exercise the right to acquire, or consummate the acquisition of, such Registered Shares), (A) such Shareholder shall not be
entitled to participate in or vote at any Preparatory Meeting, (B) in computing the majority required for the adoption of any Special Resolution or Ordinary Resolution at any Preparatory Meeting, the Registered Shares held by such Shareholder
shall be disregarded, (C) such Shareholder shall not be entitled to exercise any rights under Section 3.4 and (D) such Shareholder shall comply with all of its obligations under this Agreement, including the obligation to exercise the
voting rights attaching to such Shareholder’s Registered Shares at each General Meeting and cause the member(s) of the Board of Directors (or the alternate(s) thereof) nominated by such Shareholder to vote at each meeting of the Board of
Directors (as the case may be) in accordance with the Special Resolution(s) (as defined in Section 4.3) and/or Ordinary Resolution(s) (as the case may be) adopted at the relevant Preparatory Meeting. 

	3.8	The provisions of Section 3 shall be equally applicable to any Transfer of subscription rights corresponding to Registered Shares or any rights or instruments

of such in-kind consideration as determined in such bona fide valuation. 

  

	3.10	Any Transfer of the Registered Shares made other than strictly in accordance with the provisions of this Section 3 shall be null and void and shall not be
registered by Usiminas. 

 Section 4. Voting 

 

	4.1	Except as provided for in Section 4.15, prior to each General Meeting and each meeting of the Board of Directors, a meeting (a “Preparatory
Meeting”) shall be held among the Shareholders in order to formulate and adopt a unified position to be taken by the Shareholders at such General Meeting, or by the members of the Board of Directors nominated by the Shareholders at such
meeting of the Board of Directors, as the case may be. The Shareholders agree and covenant that they shall exercise the voting rights attaching to their Registered Shares at each General Meeting in accordance with the Special Resolution(s) (as
defined in Section 4.3) and/or Ordinary Resolution(s) (as the case may be) adopted at the relevant Preparatory Meeting, as a single, unified block. Each Shareholder further agrees and covenants to cause the member(s) of the Board of Directors
(or the alternate(s) thereof) nominated by such Shareholder to vote at each meeting of the Board of Directors in accordance with the Special Resolution(s) or Ordinary Resolution(s) (as the case may be) adopted at the relevant Preparatory Meeting.

  

	4.2	The members of the Board of Directors nominated by the Shareholders shall be responsible for the convening of Preparatory Meetings, and shall make their best endeavors
so that such meetings are held at least five (5) days before the relevant Board of Directors’ meetings or General Meetings. 

	4.3	The Shareholders agree that, except as may be otherwise provided in this Section 4.3, any decisions concerning any of the matters listed from (a) through
(m) below (i) shall be subject to a Preparatory Meeting, and (ii) shall only be adopted with the affirmative vote of Shareholders holding, in the aggregate, at least ninety percent (90%) of the total number of Registered Shares
(a “Special Resolution”): 

  

	 	(a)	increase of Usiminas’ capital through subscription of new shares, and the fixing of the issuance price(s) of such shares (including through parameters);

  

	 	(b)	reduction of Usiminas’ capital; 

  

	 	(c)	modification of Usiminas’ corporate purpose; 

  

	 	(d)	issuance of securities convertible into shares; 

  

	 	(e)	issuance of new classes of shares or alteration of the powers, preferences or rights of the existing classes of shares; 

 

	 	(f)	reorganization of Usiminas through merger or consolidation into or with another company or through a spin-off; 

 

	 	(g)	participation in a group of companies or a consortium of any kind or entering into a comprehensive strategic alliance agreement; provided, however, that any
proposed transaction falling under this item (g) shall be first presented for consideration by the Shareholders at a Preparatory Meeting and, if a Shareholder requests that Usiminas engages an independent first class investment bank or audit
firm to provide an opinion as to the fairness of the terms of such transaction, and the bank or firm so engaged concludes (after considering the information provided by all the Shareholders) that the terms of such transaction are fair to Usiminas,
then such transaction may be approved by Ordinary Resolution (i.e., no Special Resolution shall be required) at a second Preparatory Meeting; 

  

	 	(h)	dissolution, liquidation, judicial reorganization, admission of bankruptcy, or composition, or the discontinuance of any ongoing liquidation or judicial reorganization;

  

	 	(i)	determination of Usiminas’ dividend policy and subsequent modifications to that policy; 

 

	 	(j)	incurrence or granting of loans or other financings, granting of guarantees, or approval of any other action that, in each case, would result in an increase of the
amount of indebtedness exceeding two-thirds (2/3) of Usiminas’ net equity; 

  

	 	(k)	any acquisition or transfer of any permanent asset(s) or any new investment(s) for a value exceeding ten percent (10%) of the net equity of Usiminas;
provided, however, that any proposed transaction falling under this item (k) shall be first presented for consideration by the Shareholders at a Preparatory Meeting, and if a Shareholder requests that Usiminas engages an independent
first class investment bank or audit firm to prepare a fairness opinion or valuation report in connection with such transaction and the value of such transaction falls within the range of values determined by the bank or firm so engaged (after
considering the information provided by all the Shareholders), then such transaction may be approved by Ordinary Resolution (i.e., no Special Resolution shall be required) at a second Preparatory Meeting; 

	 	(l)	any capital expenditure in an amount exceeding three percent (3%) of Usiminas’ net equity, irrespective of whether any such expenditure is to be made in a
single transaction or in a series of combined or connected transactions; 

  

	 	(m)	any modification to the Bylaws which involves matters concerning the subject or the purpose of this Section 4.3. 

Notwithstanding anything to the contrary in this Section 4.3 or in any other provision of this Agreement, the Shareholders agree
that, whenever a transaction requiring approval by Special Resolution falls under item y) of article 13 of the Bylaws, then any Shareholder(s) having a direct interest in such transaction (whether as the counterparty to Usiminas in the
transaction, or as an Affiliate of the counterparty to Usiminas in the transaction) shall advise the other Shareholders thereof and abstain from participating in any deliberations concerning the transaction and from voting on its approval at the
relevant Preparatory Meeting and, in computing the majority required for the adoption of a Special Resolution in connection with such transaction, the Registered Shares held by such Shareholder(s) shall be disregarded. 

In the event that any resolution concerning any matter requiring approval by Special Resolution which has not been so approved is proposed
by any Person and/or submitted to a vote at a General Meeting or at a meeting of the Board of Directors, each Shareholder shall vote against such proposed resolution at such General Meeting or shall cause the member(s) of the Board of Directors (or
the alternate(s) thereof) nominated by such Shareholder to vote against such proposed resolution at such meeting of the Board of Directors (as the case may be). 
  

	4.4	It is hereby acknowledged and agreed that neither the approval by the Shareholders of any Special Resolution at a Preparatory Meeting concerning any matter listed from
items (a) through (m) in Section 4.3 above, nor any subsequent formal resolution adopted by Usiminas’ Board of Directors or General Meeting with the affirmative vote of the Shareholders or the members of the Board of Directors
appointed by the Shareholders (as the case may be) shall give rise to any obligation on the part of the Shareholders to contribute any funds or provide any guarantees or any other financial support or assistance to Usiminas. By way of example (and
not of limitation), if an increase of Usiminas’ capital through subscription of new shares were approved by the Shareholders at a Preparatory Meeting and then at the General Meeting with the affirmative vote of the Shareholders, the
Shareholders would have a preemptive right (direito de preferência) to subscribe such shares as provided by Law, but their approval thereof would not give rise to, nor should it be construed as, an obligation or commitment on the part
of the Shareholders to effectively subscribe for any such shares. 

	4.5	Subject to the provisions of Sections 4.6 to 4.13, there shall be a Preparatory Meeting for the nomination, removal and replacement of the Chairman of the Board of
Directors (Presidente do Conselho de Administração) and the Chief Executive Officer (Diretor-Presidente) of Usiminas, and for the examination and approval or rejection of the candidates nominated by the Chief Executive
Officer to compose the Executive Board (it being understood, for the avoidance of doubt, that no Preparatory Meeting shall be required for the nomination of the two (2) members of the Executive Board pursuant to Section 4.12).

  

	4.6	Except as provided for in §7 of Article 141 of the Corporations Law, the number of members of the Board of Directors to be elected by the General Meeting shall not
exceed the maximum number provided in the Bylaws. The Parties agree that they shall not approve any amendment to the Bylaws reducing such maximum number without the consent of all Shareholders having a right to nominate members to the Board of
Directors under this Section 4.6. In addition, the number of members of the Board of Directors to be nominated by the Parties for election at the General Meeting shall not be lower than eight (8). For each member of the Board of Directors, an
alternate member shall be elected to substitute him/her in his/her absence or in the event he/she becomes incapacitated to perform his/her office. 

 So long as NSC Group and T/T Group hold at least twenty five percent (25%) of the total number of Registered Shares each, (a) NSC and T/T Group shall, in the aggregate, nominate a majority of
the members of the Board of Directors (i.e., not fewer than half plus one of the total number of members of the Board of Directors to be appointed by the shareholders in the General Meeting) and their respective alternates, and (b) NSC and T/T
Group shall each nominate an equal number of members of the Board of Directors (and their respective alternates); provided that NSC and T/T Group shall each nominate, in any event, not fewer than three (3) members of the Board of
Directors each (and their respective alternates); and provided, further, that the members of the Board of Directors that NSC shall nominate pursuant to this Section 4.6 shall include (and not be in addition to) the member that NU
has the right to appoint pursuant to article 27 of the Bylaws. 
 In the event that the percentage of Registered Shares held by
NSC Group or T/T Group falls below twenty five percent (25%) of the total number of Registered Shares, the number of the members of the Board of Directors to be nominated by NSC and T/T Group shall be proportionally revised taking into account
their then relative holdings of Registered Shares. 

 So long as (a) CEU Group holds ten percent (10%) or more of the total number of
Registered Shares, and (b) no Person or group of Persons entitled to appoint a member of the Board of Directors in accordance with article 12, paragraph 1°, of the Bylaws shall have exercised (or presented a written indication that
it or they intend to exercise) such right at an annual General Meeting at which members of the Board of Directors are to be elected, then CEU shall nominate two (2) members of the Board of Directors (and their respective alternates). If,
however, any Person or group of Persons shall have appointed (or presented a written indication that it or they intend to appoint) a member of the Board of Directors pursuant to article 12, paragraph 1°, of the Bylaws, then CEU shall, to
the extent the condition set forth in (a) of the preceding sentence is satisfied, nominate one (1) member of the Board of Directors (and such member’s alternate). Nothing in this Agreement shall prevent CEU from representing the
employees of Usiminas or from appointing one member of the Board of Directors on their behalf; provided, however, that the member(s) nominated by CEU pursuant to this Agreement shall include (and not be in addition to) any member that CEU may
appoint on behalf of Usiminas’ employees. 
 Notwithstanding any nomination pursuant to the preceding paragraph in this
Section 4.6, CEU acknowledges and agrees that the Shareholders shall not vote for the election of any candidate for the Board of Directors nominated by CEU unless all of the members of the Board of Directors (and their respective alternates)
nominated by each of NSC and T/T Group in accordance with this Section 4.6 shall have been effectively elected by the relevant General Meeting; it being understood, for the avoidance of doubt, that the absence in the Board of Directors of any
members nominated by CEU shall not prevent, limit or otherwise restrict CEU’s rights under this Agreement, including its right to convene, participate and vote at any and all Preparatory Meetings. 

The Shareholder or Group that nominated a member of the Board of Directors shall have the right to require, at its sole discretion, the
removal or replacement at any time of such member of the Board of Directors. Any vacancy created by the death, resignation or removal of any member of the Board of Directors shall be filled by a person nominated by the Shareholder or Group that had
nominated the deceased, resigning or removed member of the Board of Directors. 
 The Parties acknowledge and agree that the
nomination of the members of the Board of Directors pursuant to this Section 4.6 shall not require approval by Special Resolution nor by Ordinary Resolution. 
  

	4.7	The Chairman of the Board of Directors shall be nominated by Ordinary Resolution, out of the persons nominated for election as members of the Board of Directors
pursuant to Section 4.6. 

  

	4.8	NSC and T/T Group shall have the right to nominate by consensus the Chief Executive Officer of Usiminas, which nomination shall be approved by way of an Ordinary
Resolution adopted with the affirmative vote of both NSC and T/T Group. The removal or replacement of the Chief Executive Officer shall require the consensus of NSC and T/T Group, which removal shall be approved also by way of an Ordinary Resolution
adopted with the affirmative vote of both NSC and T/T Group. 

	4.9	At any annual General Meeting at which members of the Board of Directors and/or the Chairman of the Board of Directors are to be elected, each Shareholder shall vote
all of its Registered Shares and any other Shares owned by it, and shall cause its Affiliates to vote any and all Shares owned by such Affiliates, in favor of: 

 

	 	(a)	the election of each of the persons nominated for election as members of the Board of Directors (and their respective alternates) pursuant to Section 4.6; it being
understood, for the avoidance of doubt, that (i) the Shareholders shall vote for the election of any candidate for the Board of Directors nominated by CEU in accordance with Section 4.6 if (but only if) all of the members of the Board of
Directors (and their respective alternates) nominated by each of NSC and T/T Group in accordance with Section 4.6 above shall have been effectively elected by the General Meeting, and (ii) the Shareholders shall vote for the election of
the second candidate for the Board of Directors (and such candidate’s alternate) nominated by CEU in accordance with Section 4.6 if (but only if) no Person or group of Persons shall have appointed (or presented a written indication that it
or they intend to appoint) a member of the Board of Directors pursuant to article 12, paragraph 1°, of the Bylaws; and 

  

	 	(b)	the election of the person nominated for election as Chairman of the Board of Directors pursuant to Section 4.7. 

Each Shareholder shall cause the member(s) of the Board of Directors (or the alternate(s) thereof) nominated by such Shareholder to vote
in favor of the election of the Chief Executive Officer nominated pursuant to Section 4.8. 
 Each Shareholder shall also be
required to vote all of its Registered Shares and any other Shares owned by it, and shall cause its Affiliates to vote any and all Shares owned by such Affiliates, at the General Meeting and/or to cause the member(s) of the Board of Directors (or
the alternate(s) thereof) nominated by such Shareholder to vote (as applicable), in favor of any removal and/or replacement of any member of the Board of Directors requested in accordance with Section 4.6, or any appointment, removal and/or
replacement of the Chief Executive Officer decided in accordance with Section 4.8. 
  

	4.10	In case an election of members of the Board of Directors at any given General Shareholders Meeting is to be made by cumulative voting (voto múltiplo)
and/or members of the Board of Directors are elected pursuant to Article 141 §4° or §5° of the Corporation Law, the Shareholders shall coordinate among themselves and vote their Registered Shares (and any other Shares owned by
them), and shall cause their Affiliates to vote any and all Shares owned by such Affiliates, at such General Meeting in such manner as may be necessary or required for the Shareholders to elect the highest possible number of members of the Board of
Directors nominated for election pursuant to Sections 4.6 (it being understood, for the avoidance of doubt, that when so doing, the Shareholders shall abide, to the maximum extent possible, by the provisions of Sections 4.6 and 4.9).

	4.11	The Executive Board shall consist of one (1) Chief Executive Officer and two (2) to six (6) additional members (with or without specific designation,
office or function). 

  

	4.12	NSC shall have the right to nominate one (1) member of the Executive Board (in addition to the right to nominate by consensus with T/T Group the Chief Executive
Officer under Section 4.8), and to remove and/or replace such member at any time in its sole discretion. 

Ternium shall have the right to nominate one (1) member of the Executive Board (in addition to its right, as part of T/T Group, to
nominate by consensus with NSC the Chief Executive Officer under Section 4.8), and to remove and/or replace such member at any time in its sole discretion. 
 The Parties acknowledge and agree that the nomination of the members of the Executive Board pursuant to this Section 4.12 shall not require approval by Special Resolution nor by Ordinary Resolution.

  

	4.13	The Chief Executive Officer nominated pursuant to Section 4.8 for a given period shall nominate the members of the Executive Board for such period (other than the
persons nominated by NSC and by Ternium pursuant to Section 4.12), which nomination shall be subject to approval by the Shareholders by Ordinary Resolution adopted at a Preparatory Meeting. The members of the Executive Board nominated by the
Chief Executive Officer shall be professionals trusted by the Chief Executive Officer, in his/her discretion. Members of the Executive Board (other than the members nominated by NSC and by Ternium pursuant to Section 4.12) may be removed and/or
replaced pursuant to an Ordinary Resolution adopted at a Preparatory Meeting or upon request by the Chief Executive Officer, provided that any such removal and/or replacement requested by the Chief Executive Officer shall require approval by
the Shareholders by Ordinary Resolution adopted at a Preparatory Meeting; and provided, further, that the Chief Executive Officer shall nominate the replacement member for any member so removed or replaced. 

Each Shareholder shall cause the member(s) of the Board of Directors (or the alternate(s) thereof) nominated by such Shareholder to vote
at the meeting of the Board of Directors in favor of (a) the election of the persons nominated for election as members of the Executive Board pursuant to Section 4.12 and this Section 4.13 and (b) the removal or replacement of
any such members in accordance with Section 4.12 or this Section 4.13, as applicable. 
  

	4.14	The Shareholders agree that the adoption of a resolution at a Preparatory Meeting concerning any matter to be submitted to, or to be resolved upon by, a General Meeting
or a meeting of the Board of Directors, other than those matters requiring approval by Special Resolution under Section 4.3, shall require approval by Ordinary Resolution. In the event that any resolution concerning any matter requiring
approval by Ordinary Resolution which has not been so approved is proposed by any Person and/or submitted to a vote at a General Meeting or at a meeting of the Board of Directors, each Shareholder shall vote against such proposed resolution at such
General Meeting or shall cause the member(s) of the Board of Directors (or the alternate(s) thereof) nominated by such Shareholder to vote against such proposed resolution at such meeting of the Board of Directors (as the case may be).

 The Shareholders agree that the multiannual investment budget (or any annual revisions
thereof) shall be presented to the Shareholders at a Preparatory Meeting prior to its formal consideration and approval by the Board of Directors; provided, however, that, notwithstanding anything to the contrary in this Section 4.14 or
in any other provision of this Agreement, it is understood and agreed that such presentation shall be made for informational purposes only and any investment budget (or annual revision thereof) so presented shall not be binding. 

 

	4.15	Notwithstanding anything to the contrary in Section 4.14 or in any other provision of this Agreement, the Shareholders agree that, whenever a transaction which
does not require approval by Special Resolution falls under item y) of article 13 of the Bylaws, then such transaction shall not be considered or approved at a Preparatory Meeting, and the Shareholders shall not be required to adopt a unified
position thereon. The Shareholders acknowledge and agree that the approval of any such transactions shall be subject to the applicable rules provided in the Law and in the Bylaws, and that the members of the Board of Directors (and their alternates)
nominated by the Shareholders pursuant to this Agreement shall be free to vote on the approval of any such transaction as they consider appropriate and with due observance of their duties under applicable Law and the applicable provisions of the
Bylaws, and that such members of the Board of Directors (and their alternates) shall not be required (nor shall they be deemed to be bound hereunder) to exercise their vote to favor any Party or any Affiliate of any Party in any way.

 Section 5. Term 
  

	5.1	(a) This Agreement shall be effective as from the Execution Date. 

  

	 	(b)	This Agreement shall be valid until (and including) November 6, 2031 (the “Termination Date”); provided, however, that, unless
Shareholders representing more than ten percent (10%) of all the Registered Shares give written notice that they elect not to renew this Agreement at least one hundred and eighty (180) days prior to the Termination Date, this Agreement
shall renew automatically and be extended for an additional five-year term and, upon expiration of such additional five-year term, shall renew automatically and be extended for subsequent and consecutive five-year terms, unless Shareholders
representing more than ten percent (10%) of all the Registered Shares give written notice that they elect not to renew this Agreement at least one hundred and eighty (180) days prior to the end of any subsequent five-year term.

	5.2	The Shareholders acknowledge that, as from the Execution Date, the terms of the Original Agreement are superseded in their entirety by the terms of this Agreement.

  

	5.3	Without prejudice to the foregoing, as from November 6, 2016, CEU shall have the option (but not the obligation) to, on the terms and subject to the conditions
provided in this Section 5.3, withdraw all (but not less than all) of its Registered Shares from this Agreement, and thereby relinquish all its rights and be released from all its obligations hereunder (except for such rights and obligations
indicated in this Section 5.3) by delivering prior written notice to that effect to all other Shareholders and to Usiminas (the “CEU Withdrawal Notice”). 

 

	 	(a)	Upon receipt of the CEU Withdrawal Notice, the other Shareholders shall have the option (but not the obligation) to acquire all (and no less than all) of the Registered
Shares then owned by CEU (the “Section 5.3 Shares”), at a price per share equal to the average, weighted by the volume of transactions, of the closing prices of the last forty (40) trading days of BM&FBovespa
immediately prior to (but excluding) the date on which the CEU Withdrawal Notice is given. Any Shareholder wishing to exercise such option shall, within sixty (60) days after receipt of the CEU Withdrawal Notice (the
“Section 5.3 Period”), give notice to CEU, the other Shareholders and Usiminas stating such Shareholder’s irrevocable election to purchase, directly and/or through one or more of its Affiliates, either its pro rata
portion or all of the Registered Shares then owned by CEU (the “Section 5.3(a) Exercise Notice”), it being understood and agreed that if a Shareholder does not give such notice, that Shareholder shall be deemed to have
chosen not to exercise its option under this Section 5.3(a). For the purpose of this Section 5.3(a), the applicable “pro rata portion” of each Shareholder shall be such proportion, expressed in percentage terms, as
(x) the number of Registered Shares owned by such Shareholder bears to (y) the aggregate number of Registered Shares owned by all Shareholders, excluding the Registered Shares owned by CEU. 

Shareholders who provide a Section 5.3(a) Exercise Notice shall have the right (and the obligation) to acquire the Section 5.3
Shares; provided that they acquire all (and not less than all) of such Section 5.3 Shares. Unless otherwise agreed among all Shareholders who provide a Section 5.3(a) Exercise Notice, the allocation of such Section 5.3 Shares
among such Shareholders shall be made in accordance with the same rules provided in paragraphs (i) and (ii) of Section 3.4(b) (it being understood, for the avoidance of doubt, that the option contemplated in subparagraph (D) of
paragraph (ii) of Section 3.4(b) shall apply also in the context of this Section 5.3(a)), which shall be applied mutatis mutandis as if: 
  

	 	(i)	references to “Shareholder(s) belonging to the same Group as the Transferring Shareholder” were references to “Shareholder(s) belonging to any
Group other than CEU’s Group”; 

	 	(ii)	references to “Right of First Refusal Exercise Notice” were references to “Section 5.3(a) Exercise Notice”;

  

	 	(iii)	references to “Section 3.4 Shares” were references to “Section 5.3 Shares”; 

 

	 	(iv)	references to “on the same terms as the Material Original Terms (subject to Section 3.4(f))” were references to “at a price per share
equal to the average, weighted by the volume of transactions, of the closing prices of the last forty (40) trading days of BM&FBovespa immediately prior to (but excluding) the date on which the CEU Withdrawal Notice is given”; and

  

	 	(v)	references to “the expiration of the Section 3.4(b) Purchase Period” were references to “the expiration of the term provided in the last
paragraph of this Section 5.3(a)”. 

 Any and all purchases of Section 5.3 Shares pursuant to
this Section 5.3(a) must be consummated within thirty (30) days after the expiration of the Section 5.3 Period; provided, however, that in the event that any Government Authorizations are required as a condition to the
consummation of any Transfer of Section 5.3 Shares pursuant to this Section 5.3(a), the term to consummate such Transfer shall commence on the date on which the Government Authorizations required to consummate such Transfer are obtained
(and the Shareholder involved in such Transfer shall give notice to all other Shareholders and Usiminas promptly upon such Government Authorizations are obtained) and; provided, further, that (i) each Shareholder involved in such
Transfer (A) promptly takes or causes to be taken all actions, and does or causes to be done all things, necessary, proper or advisable on its part under applicable Law to obtain all requisite Government Authorizations as soon as reasonably
practicable and (B) in good faith keeps the other Shareholders and Usiminas apprised of the status of matters relating to the obtaining of such Government Authorizations (including giving notice to the other Shareholders and Usiminas promptly
upon such Government Authorizations shall have been obtained); (ii) the applicable purchase price payable for the relevant Section 5.3 Shares shall be subject to monetary adjustment from the date that is three (3) months from the date
of the relevant Section 5.3(a) Exercise Notice until the date on which the Transfer of the relevant Section 5.3 Shares is consummated, by the Taxa SELIC (Sistema Especial de Liquidação e Custódia) published by
the Comitê de Política Monetária (COPOM), or other rate that might replace it, accrued on a monthly basis; and (iii) if such Government Authorizations are denied or the Shareholder involved in such Transfer chooses to
desist from the Transfer, the provisions of Section 5.3(c) shall apply. 

	 	(b)	If no Shareholder exercises the option contemplated by Section 5.3(a), or if the Shareholder(s) who have exercised such option shall have failed to consummate the
purchase of all the Section 5.3 Shares in accordance with Section 5.3(a), then, effective as from (A) if no Shareholder shall have exercised the option contemplated by Section 5.3(a), the day immediately following the
expiration of the Section 5.3 Period or (B) if the Shareholder(s) who have exercised such option shall have failed to consummate the purchase of all the Section 5.3 Shares in accordance with Section 5.3(a), the day that is
thirty-one (31) days after the expiration of the Section 5.3 Period (the “CEU Withdrawal Effective Date”), CEU shall be deemed to have relinquished all its rights and shall be released from its obligations under
this Agreement (except for the obligations contemplated by Section 6, which shall survive for the period stated in the last paragraph thereof), and the Registered Shares owned by CEU shall cease to be bound by this Agreement, except that, until
the Termination Date, CEU shall continue to be bound by the obligations provided by Section 3.4 of this Agreement, and the Registered Shares owned by CEU shall continue to be bound by Section 3.4 and, accordingly, CEU may not, prior to the
Termination Date, Transfer any such Shares to any Person without granting the Shareholders the right of first refusal provided by Section 3.4 of this Agreement; provided, however, that the obligations provided by Section 3.4 of this
Agreement shall not apply in respect to: 

  

	 	(i)	any sale of Shares by CEU made through BM&FBovespa after the CEU Withdrawal Effective Date, it being agreed that the number of Shares sold in reliance on this
proviso on any day may not exceed twenty-five percent (25%) of the average daily reported volume of trading of the Shares on the BM&FBovespa for the month preceding the month in which such sale is made; or 

 

	 	(ii)	any block trade on BM&FBovespa or any public offering not qualifying under clause (i) above; provided that: 

 

	 	(A)	CEU shall have first granted all the Shareholders the option to acquire all (but not less than all) of the Shares proposed to be sold by CEU through any such block
trade or offering, at a price per share equal to the average, weighted by the volume of transactions, of the closing prices of the last five (5) trading days of BM&FBovespa immediately prior to (but excluding) the date on which CEU gives
notice (the “CEU Section 5.3(b)(ii)(A) Notice”) to all the Shareholders (with a copy to Usiminas) to that effect. Upon receipt of such notice from CEU, the procedure contemplated by Section 5.3(a) shall, mutatis
mutandis, be followed; provided that, for the purpose of the exercise of the option contemplated by this subparagraph (A), the “Section 5.3 Period” shall be the fifteen-day (15-day) period following receipt of the
CEU Section 5.3(b)(ii)(A) Notice, and that the purchase of the relevant CEU’s Shares under this Section 5.3(b)(ii)(A) must be consummated within forty five (45) days after the expiration of such period. Notwithstanding the
foregoing, in the event that any Government Authorizations are required as a condition to the consummation of any Transfer of CEU’s Shares pursuant to this Section 5.3(b)(ii)(A), the term to consummate such Transfer shall commence on the
date on which the Government Authorizations required to consummate such Transfer are obtained (and the Shareholder involved in such Transfer shall give notice to all other Shareholders, CEU and Usiminas promptly upon such Government Authorizations
are obtained); provided that (x) each Shareholder involved in such Transfer (1) promptly takes or causes to be taken all actions, and does or causes to be done all things, necessary, proper or advisable on its part under applicable
Law to obtain all requisite Government Authorizations as soon as reasonably practicable and (2) in good faith keeps the other Shareholders and Usiminas apprised of the status of matters relating to the obtaining of such Government
Authorizations (including giving notice to the other Shareholders and Usiminas promptly upon such Government Authorizations shall have been obtained); (y) the applicable purchase price payable for the relevant Shares shall be subject to
monetary adjustment from the date that is three (3) months from the date of the relevant exercise notice until the date on which the Transfer of the relevant Shares is consummated by the Taxa SELIC (Sistema Especial de
Liquidação e Custódia) published by the Comitê de Política Monetária (COPOM), or such other rate that might replace it, accrued on a monthly basis; and (z) if such Government Authorizations
are denied or the Shareholder involved in such Transfer chooses to desist from the Transfer, the provisions of Section 5.3(c) shall apply. 

	 	(B)	if (i) no Shareholder exercises the option contemplated by subparagraph (A) above, or (ii) if the Shareholder(s) who have exercised such option shall
have failed to consummate the purchase of all of the relevant CEU’s Shares, then the proposed block trade or offering may be made only if completed within sixty (60) days after expiration of the term for the Shareholders’
exercise of the option contemplated by subparagraph (A) above. 

 Any Transfer of Shares by CEU following
delivery of the CEU Withdrawal Notice made other than strictly in accordance with the provisions of Section 5.3(a) or Section 5.3(b) shall be null and void and shall not be recognized or registered by Usiminas. 

 

	 	(c)	Whenever a Shareholder gives a Section 5.3(a) Exercise Notice or exercises the option contemplated in subparagraph (A) of Section 5.3(b)(ii) and,
thereafter, fails to consummate any such Transfer within the applicable purchase period, such Shareholder shall, pursuant to the terms of the relevant share purchase agreement, if any, indemnify CEU for, and shall pay to CEU the amount of, any loss,
liability, claim, damage (but excluding incidental and consequential damages), expense (including, without limitation, costs of investigation and defense and reasonable attorney fees) or diminution of value suffered or incurred by the CEU as a
result of such failure. 

 Section 6. Confidentiality 
 Each Party shall treat all non-public data and information (the “Confidential Information”) furnished to it by another Party or Usiminas (“Disclosing
Party”) in connection with this Agreement as confidential, and shall take or cause to be taken such reasonable precautions as are necessary to prevent disclosure of any Confidential Information to any other Person; provided,
however, that the first-mentioned Party may disclose Confidential Information: 
  

	 	(a)	with the prior written authorization of the Disclosing Party; 

  

	 	(b)	if disclosure is required under applicable Law; provided, however, that the Party that is so required to disclose any Confidential Information shall, to the
extent not prohibited by such Law, give the Disclosing Party prompt written notice thereof so that the Disclosing Party may seek a protective order or other appropriate remedy; 

 

	 	(c)	if the Confidential Information was part of the public domain at the time of its disclosure to such Party; 

 

	 	(d)	if the Confidential Information becomes generally available to the public or otherwise part of the public domain after its disclosure to such Party, other than through
any act or omission of a Party in breach of this Section 6; 

  

	 	(e)	if the Confidential Information was subsequently disclosed to such party by a third party on a non-confidential basis; provided that such third party is not
known by such Party to be bound to any confidentiality duty or obligation (whether to the Disclosing Party or any other Person) with respect to such Confidential Information; 

 

	 	(f)	if such Party can demonstrate that the Confidential Information was already in such Party’s possession at the time of disclosure by the Disclosing Party and was
not acquired, directly or indirectly, from the Disclosing Party on a confidential basis; or 

  

	 	(g)	to the extent necessary (i) to enforce such Party’s rights under this Agreement or (ii) in connection with such Party’s defense of any action, suit
or proceeding relating to this Agreement. 

 Each Party may disclose any Confidential Information to its
Affiliates and to its and its Affiliate’s directors, officers, employees, auditors and legal, accounting, tax and other advisors, who reasonably need to have access to such information; provided that each Party shall take all reasonable
measures to cause such Persons to abide by the confidentiality obligations provided by this Section 6 and shall be liable for any breach of such confidentiality obligations by any such Person. The Parties acknowledge and agree that Confidential
Information may be used only for the purpose of this Agreement. 
 The confidentiality obligations in this Section 6 shall
survive termination of this Agreement for a period of five (5) years from such termination. 

 Section 7. Deposit of Agreement and Registration of Shares 

One copy of this Agreement shall be deposited at the head office of Usiminas and all applicable provisions of this Agreement concerning
the Registered Shares shall be registered in the Usiminas’s share register and on the certificates evidencing the Registered Shares. Usiminas shall notify all Shareholders of any Transfer or attempted Transfer of Registered Shares. 

Section 8. Governing Law and Jurisdiction 
  

	8.1	This Agreement shall be governed by the Law of the Federative Republic of Brazil (including Articles 466-A to 466-C of the Civil Process Code which shall apply to any
breach by a Party of the obligations assumed herein), without giving effect to the conflict of laws principles thereof. Any action or proceeding seeking to enforce any provision of, or based on any right arising out of, this Agreement may be brought
against any of the Parties in the Courts of the City of Belo Horizonte, State of Minas Gerais, and each of the Parties hereby consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such action or
proceeding and waives any objection which it may now or hereafter have to the laying of the venue of any such action or proceeding in any such court or that any such action or proceeding which is brought in any such court has been brought in an
inconvenient forum. 

 Section 9. General Provisions 

 

	9.1	Except as otherwise provided in this Agreement, no Party may assign any of its rights or obligations under this Agreement in whole or in part without the prior written
consent of the other Parties. Subject to the preceding sentence, this Agreement shall apply to, be binding in all respects upon, and inure to the benefit of, any successors and permitted assigns of the Parties. 

 

	9.2	All notices, consents, waivers, and other communications under this Agreement must be in writing and in the English language and shall be deemed to have been duly given
when (a) delivered by hand (with written confirmation of receipt), (b) sent by fax or electronic mail (with written confirmation of receipt), provided that a copy is mailed by registered mail, return receipt requested, or
(c) when received by the addressee, if sent by an internationally recognized courier service (receipt requested), in each case to the appropriate addresses, fax numbers and electronic addresses set forth in Appendix 1 hereto (or to such other
addresses, fax numbers and electronic addresses as any Party may designate by notice to the other Parties). 

  

	9.3	The Parties agree that irreparable damage would occur in the event any provision of this Agreement was not performed in accordance with the terms hereof and that the
Parties shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or set forth herein. The Parties further agree that Article 118 of Law 6404/1976 (as such is amended or replaced from time to time) as well
as articles 461 and 632 through 645 of the Brazilian Code of Civil Procedure (as such are amended or replaced from time to time) shall apply to this Agreement in full and each Party shall be entitled to the specific performance provisions set out
therein. 

	9.4	If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement shall remain in full
force and effect. Any provision of this Agreement held invalid or unenforceable only in part shall remain in full force and effect to the extent not held invalid or unenforceable. If this Agreement continues in full force and effect as provided
above, the Parties shall replace the invalid provision with a valid provision which corresponds as far as possible to the spirit and purpose of the invalid provision. 

 

	9.5	The rights and remedies of the Parties under this Agreement are cumulative and not alternative. Neither the failure nor any delay by any Party in exercising any right,
power, or privilege under this Agreement shall operate as a waiver of such right, power, or privilege, and no single or partial exercise of any such right, power, or privilege shall preclude any other or further exercise of such right, power, or
privilege or the exercise of any other right, power, or privilege. 

  

	9.6	Usiminas signs this Agreement as evidence of acknowledgement and confirmation of its filing in Usiminas’ headquarters, and hereby declares to have knowledge of all
its terms. Usiminas further agrees to take any action on its part required to be taken under this Agreement. 

  

	9.7	This Agreement replaces and supersedes the A&RSHA. In the event of any inconsistencies between the terms of this Agreement and the terms of the Portuguese-language
agreement entitled “Acordo de Acionistas Aditado e Consolidado” among the Parties dated the Execution Date, the latter shall govern and prevail. 

 

	9.8	The headings of Sections in this Agreement are provided for convenience only and shall not affect its construction or interpretation. All references to
“Section” or “Sections” refer to the corresponding Section or Sections of this Agreement. All words used in this Agreement shall be construed to be of such gender or number as the circumstances require. Unless otherwise
expressly provided, the word “including” shall be construed as inclusive without limitation, in each case notwithstanding the absence of any express statement to such effect, or the presence of such express statement in some contexts and
not in others. 

  

	9.9	This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original copy of this Agreement and all of which, when taken
together, shall be deemed to constitute one and the same agreement.
