(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.

3.2Optional 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.

3.3Mandatory 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).

3.4Other 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).

3.5Illegality. (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.

(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.

3.6No Reborrowing. Amounts paid or prepaid pursuant to any provisions of this Agreement may not be reborrowed.

4.INTEREST

4.1Basic 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”).

(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).

4.2Default 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.

4.3Alternative 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.

4.4Interest 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.

4.5Exchange 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.

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;providedfurther,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.

(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 successor provision) of the Mexican Income Tax Law (Ley del Impuesto sobre la Renta) in excess of the amount that the Obligors would have been required to pay if such Bank had been so registered and were a resident in a jurisdiction with which Mexico has entered into a treaty for the avoidance of double taxation which is in effect and had met the requirements set forth in such treaty for a reduced withholding tax rate, for so long as such requirement remains applicable.

5.2Stamp Taxes. Each Borrower shall pay any registration or transfer taxes, stamp duties or similar levies, and any penalties or interest that may be due with respect thereto, that may be imposed by or within Mexico or any political subdivision or taxing authority thereof or therein in connection with the execution of the Loan Documents. If the Administrative Agent or any Bank pays any amount that it is required to pay under applicable law in respect of any such taxes, duties, levies, penalties or interest, the applicable Borrower shall reimburse the Administrative Agent or such Bank for such payment in Dollars within thirty days from written demand.

5.3Tax Indemnity. Each Borrower agrees to indemnify each Bank and the Administrative Agent for the full amount of any Taxes described in Section 5.1 or 5.2 paid by such Bank or the Administrative Agent, and any liability (including penalties, interest and reasonable expenses) arising there from or with respect thereto, which amounts arise from the failure of such Borrower to pay any such Taxes. Payment of such amount shall be made within thirty days from the date such Bank or the Administrative Agent makes written demand therefor.

6.2Computations. Interest and fees payable hereunder shall be computed on the basis of a 360 day year and actual days elapsed;provided,however, that to the extent the Alternative Rate is used at times when such Alternative Rate is calculated pursuant to clause (a) of the definition thereof, such rate shall be determined on the basis of a year of 365 or 366 days and actual days elapsed.

11.ASSIGNMENTS AND ASSUMPTIONS.

11.1Assignment.

Upon (i) such execution of such 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 in the case of an assignment to an Affiliate of the assigning Bank and (iv) payment by such Purchasing Bank to such transferor Bank of an amount equal to the purchase price agreed between them, such Purchasing Bank shall for all purposes be a 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.

11.2Participations. 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.

11.3Disclosure 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.

11.4Pledge 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

12.1Application 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.

12.2Sharing 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; andprovidedfurther,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.

13.THE ADMINISTRATIVE AGENT

13.1Appointment. 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.

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.

13.4Reliance 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.

13.5Notice 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.

13.6Non-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.

13.7Indemnification. 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.

13.8Non 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.

(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.

13.9Administrative 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.

13.11No Other Duties. Except as expressly set forth herein, the Administrative Agent shall have no duties or responsibilities hereunder in its capacity as such.

13.12The 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

14.1Initial 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).

14.2Amendment 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.

14.3Other 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.

14.4Increased 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

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; andprovidedfurtherthat 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.

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.

14.5Information. 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).

14.6General 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

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

15.2Jurisdiction. (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.

(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.

15.3Loan 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.

15.4Notes. (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”).

(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 signaturespor 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 signaturespor 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.

L. 107-56 (signed into law October 26, 2001)), it may be required to obtain, verify and record information that identifies such Borrower, which information includes the name and address of such Borrower and other information that will allow such Bank or the Administrative Agent, as applicable, to identify such Borrower in accordance with said Act.

16.2Obligations 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;

(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.

16.3Reinstatement. 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.

16.4Subrogation. 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.

16.5Acceleration. 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.

16.6Instrument 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.

16.7Continuing Guarantee. The guarantee in this Article 16 is a continuing guarantee, and shall apply to all Guaranteed Obligations whenever arising.

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.

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 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;
