Each Bank shall promptly provide notice of any such set-off by it to such Obligor, as applicable, and the Administrative Agent; provided that failure by such Bank to provide such notice shall not give such Obligor any cause of action or right to damages or affect the validity of such set-off and application.

counterclaim or cross action, by the enforcement of any right under the Credit Documents, or otherwise), which is applicable to the payment of the principal of, or interest on, the Loans, or fees due hereunder, of a sum which with respect to the related sum or sums received by other Banks is in a greater proportion than the total of such Obligation then owed and due to such Bank bears to the total of such Obligation then owed and due to all of the Banks immediately prior to such receipt, then such Bank receiving such excess payment shall purchase for cash without recourse or warranty from the other Banks an interest in the Obligations of the Borrower to such Banks in such amount as shall result in a proportional participation by all the Banks in such amount; provided that if all or any portion of such excess amount is thereafter recovered from such Bank, such purchase shall be rescinded and the purchase price restored to the extent of such recovery, but without interest.

(c) Nothing contained in this Section shall require any Bank to exercise any such right or shall affect the right of any Bank to exercise, and retain the benefits of exercising, any such right with respect to any other Debt or obligation of the Obligors.

(d) If any Obligor (or any Person on its behalf) makes a payment to the Administrative Agent, or any Bank exercises its right of set-off, and such payment or the proceeds of such set-off or any part thereof subsequently are invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by such Bank in its discretion) to be repaid to such Obligor (or such Person), a trustee, síndico, receiver or any other Person in connection with any insolvency proceeding or otherwise, then: (i) to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such set-off had not occurred, and (ii) if applicable, each Bank severally agrees to pay to the Administrative Agent upon demand its pro rata share of any amount so recovered from or repaid by the Administrative Agent.

ARTICLE IV

YIELD PROTECTION, ETC.

Section 4.1 Increased Costs.

(a) If the adoption of any Applicable Law, or any change in any Applicable Law, or any change in the interpretation or administration thereof by any Governmental Authority charged with the interpretation or administration thereof, or compliance by any Bank (or its Lending Office) with any request or directive (whether or not having the force of law) of any Governmental Authority (in each case above, at any time on or after the date hereof), shall impose, modify or deem applicable any reserve (including any such requirement imposed by the Board of Governors of the U.S. Federal Reserve System), special deposit, insurance assessment or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Bank (or its Lending Office) or shall impose upon any Bank (or its Lending Office) or the London interbank market any other condition affecting its Commitment, its Loans, its Note or its obligation to purchase or maintain its Loans, and the result of any of the foregoing is to increase the cost to such Bank (or its Lending Office) of maintaining its Commitment or disbursing or maintaining its Loans, or to reduce the amount of any sum received or receivable by such Bank (or its Lending Office) under this Agreement or under any other Credit Document, then upon the written request of such Bank, the Borrower shall pay to the Administrative Agent for the account of such Bank such additional amount(s) as will compensate such Bank for such increased cost or reduction. Notwithstanding anything contained herein, the Borrower shall not be liable for any amount contemplated by this Section 4.1(a) to be paid by the Borrower that shall arise more than 180 days prior to receipt by the Borrower of such written request.

(b) If any Bank shall have reasonably determined that the adoption of any Applicable Law regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any Governmental Authority charged with the interpretation or administration thereof, or compliance by it (or its Lending Office) with any request or directive regarding capital adequacy (whether or not having the force of law) of any Governmental Authority (in each case above, at any time on or after the date hereof), has or would have the effect of reducing the rate of return on capital of such Bank (or its parent or Lending Office) as a consequence of such Bank’s obligations hereunder, its Commitment or its Loans to a level below that which such Bank (or its parent or Lending Office) could have achieved but for such adoption, change, request or directive, then upon written demand by such Bank, the Borrower, from time to time, shall pay to such Bank such additional amount as will compensate such Bank (or its parent or Lending Office, as the case may be) for such reduction. Each Bank shall promptly notify the Borrower (with a copy to the Administrative Agent) of any event of which it has knowledge that will entitle such Bank to compensation pursuant to this Section and shall provide the Borrower (with a copy to the Administrative Agent) with a certificate setting forth in reasonable detail the basis of such Bank’s claim and the calculation of the amount of the request by such Bank for compensation pursuant to this Section. A certificate from any Bank claiming compensation under this Section and providing the information set forth above within the time set forth above shall be prima facie evidence of its entitlement to such compensation and shall, absent manifest error, be conclusive, provided that such determinations

Gerdau Credit Agreement

and allocations are made on a reasonable basis and are mathematically accurate. Such amounts shall be payable by the Borrower promptly (and, in any event, within five (5) Business Days) after receipt of such certificate (or, if such compensation relates to future dates, by no later than the applicable dates indicated in such notice). The payment of any such amount by the Borrower shall not preclude the Borrower from contesting such calculation in accordance with the terms of this Agreement. Notwithstanding anything contained herein, the Borrower shall not be liable for any amount contemplated by this Section 4.1(b) to be paid by the Borrower that shall arise more than 180 days prior to receipt by the Borrower of such certificate.

(c) At any time that by reason of Regulation D of the Board of Governors of the Federal Reserve System such Bank is required to maintain reserves in respect of Eurocurrency liabilities (as defined in Regulation D) during any period that it has a Loan outstanding (each such period, for any Bank, a “Eurocurrency Reserve Period”), then such Bank shall promptly give written notice to the Borrower and to the Administrative Agent of such determination (which notice the Administrative Agent shall promptly transmit to each of the other Banks), and the Borrower shall pay to the Administrative Agent on behalf of such Bank additional interest on the unpaid principal amount of each Loan of such Bank during such Eurocurrency Reserve Period at a rate per annum which shall, during each Interest Period applicable to such Loan, be the amount by which (i) the LIBO Rate for such Interest Period divided (and rounded upward to the next whole multiple of 1/00 of 1%) by a percentage equal to 100% minus the then stated maximum rate of all reserve requirements (including, without limitation, any marginal, emergency, supplemental, special or other reserves) applicable to any member bank of the Federal Reserve System in respect of Eurocurrency liabilities (as defined in Regulation D) exceeds (ii) the LIBO Rate for such Interest Period. Additional interest payable pursuant to the immediately preceding sentence shall be paid by the Borrower at the time that it is otherwise required to pay interest in respect of such Loan or, if later demanded by the Bank, promptly on written demand. Notwithstanding anything contained herein, the Borrower shall not be liable for any amounts contemplated by this Section 4.1(c) to be paid by the Borrower that shall arise more than 180 days prior to receipt by the Borrower of such written notice or demand. Each Bank agrees that if it gives notice to the Borrower of the existence of a Eurocurrency Reserve Period, it shall promptly notify the Borrower of any termination thereof, at which time the Borrower shall cease to be obligated to pay additional interest on behalf of such Bank until such time, if any, as a subsequent Eurocurrency Reserve Period shall occur.

Section 4.2 Substitute Basis. If, on or before the first day of any Interest Period (an “Affected Interest Period”):

(a) the Administrative Agent determines that, by reason of circumstances affecting the London interbank market, the LIBO Rate cannot be determined for such Affected Interest Period pursuant to the definition thereof, or

(b) the Majority Banks determine and notify the Administrative Agent that the LIBO Rate for such Affected Interest Period will not be adequate to cover the cost to such Banks of making or maintaining their Loans for such Affected Interest Period;

then, each Bank shall determine (and shall certify from time to time in a certificate delivered by such Bank to the Administrative Agent setting forth in reasonable detail the basis of the

Gerdau Credit Agreement

computation of such amount) the rate basis reflecting the cost to such Bank of funding its Loan for the Affected Interest Period, and such rate basis shall be binding upon the Borrower and shall apply in lieu of the LIBO Rate for such Interest Period (such certification to be conclusive and binding on the Borrower in the absence of manifest error); provided that the rate basis certified by the Bank to the Administrative Agent in accordance with this Section shall not be greater than the Base Rate on the date of delivery of the corresponding certificate by the Bank to the Administrative Agent.

Section 4.3 Illegality. Notwithstanding any other provision of this Agreement, if the adoption of or any change in any Applicable Law or in the interpretation or application thereof by any Governmental Authority (in each case, at any time on or after the date hereof) shall make it (or be asserted by it to be) unlawful for any Bank or its Lending Office to honor its obligation to make or maintain its Loan hereunder (and, in the opinion of such Bank, the designation of a different Lending Office would either not avoid such unlawfulness or would be disadvantageous to such Bank), then such Bank shall promptly notify the Borrower thereof (with a copy to the Administrative Agent), following which notice: (a) such Bank’s Commitment (if still available) shall be suspended until such time as such Bank may again make and maintain its Loan or (b) if such Applicable Law shall so mandate, such Bank’s Loan shall be prepaid by the Borrower, together with accrued and unpaid interest thereon and all other amounts payable to such Bank by the Borrower under the Credit Documents, on or before such date as shall be mandated by such Applicable Law (such pre-payment not being shared as described in Section 2.12(b) with any Banks not so affected); provided that if it is lawful for such Bank to maintain its Loan until the next Interest Payment Date, then such payment shall be made on such Interest Payment Date. Any such funds so prepaid may not be reborrowed.

Section 4.4 Funding Losses.

(a) The Borrower shall pay to the Administrative Agent for the account of each Bank, upon the request of such Bank through the Administrative Agent, such amount as shall be sufficient (in the reasonable opinion of such Bank) to compensate each Bank for any loss, cost or expense (excluding the loss of any anticipated profits but including any such loss, cost or expense arising from the liquidation or reemployment of funds obtained by such Bank to fund its Loan or from fees payable to terminate the deposits from which such funds were obtained) that such Bank determines is attributable to:

(i) any optional or mandatory pre-payment (including as a result of an acceleration due to an Event of Default) of any Loan made by the Borrower for any reason on a date other than an Interest Payment Date, or the Scheduled Maturity Date of a Loan occurs on a date which is not an Interest Payment Date,

(ii) any failure by the Borrower for any reason to prepay the Loans (or any portion thereof) in accordance with a notice of pre-payment under Section 2.7; or

(iii) the Borrowing does not occur on a requested Borrowing Date specified in the Notice of Borrowing given pursuant to Section 2.2 for any reason (including the failure of any of the conditions precedent specified in Article VI to be

Gerdau Credit Agreement

satisfied, but excluding any non-occurrence of the Borrowing resulting solely from such Bank’s gross negligence or willful misconduct).

(b) Each Bank shall furnish to the Administrative Agent (which shall promptly notify the Borrower) a certificate setting forth the basis and amount of each request by such Bank for compensation under this Section, which certificate shall provide reasonable detail as to the calculation of such loss, cost or expense, and shall, absent manifest error, be conclusive and binding upon the Borrower.

Section 4.5 Taxes.

(a) All payments made by or on behalf of the Borrower or any Guarantor hereunder or under any Note will be made free and clear of, and without deduction or withholding for, any present or future taxes, levies, imposts, duties, fees, assessments or other charges or withholdings of whatever nature now or hereafter imposed by the United States, Brazil, Canada or any jurisdiction from which payments are made or by any political subdivision or taxing authority of any thereof or therein with respect to such payments (but excluding any tax imposed on or measured by the net income or net profits or any Canadian capital tax (and any real property, capital, franchise, net receipts or similar tax imposed in lieu of or as an alternative to any such tax) of the Administrative Agent or a Bank pursuant to the Applicable Laws of the jurisdiction (or any political subdivision or taxing authority thereof or therein) in which it is organized or in which the principal office or Lending Office of such Bank is located or any jurisdiction which imposes such a tax as a result of a present or former connection between the jurisdiction and such Administrative Agent or Bank other than a connection resulting from a transaction contemplated by this Agreement) and all interest, penalties or similar liabilities with respect thereto (all such non-excluded taxes, collectively, “Taxes”). Subject to Section 12.3(b), if any Taxes are so levied or imposed, each of the Borrower or such Guarantor, as applicable, agrees to pay the full amount of such Taxes, and such additional amounts as may be necessary so that every payment of all amounts due hereunder or under any Note, after withholding or deduction for or on account of any Taxes, will not be less than the amount provided for herein or in such Note. The Borrower or such Guarantor, as applicable, will timely furnish to the Administrative Agent original tax receipts, notarized copies of tax receipts or such other documentation as will prove payment of tax, for all Taxes paid by the Borrower pursuant to this Section 4.5. Each of the Borrower and the Guarantors agrees to indemnify and hold harmless each Bank, and reimburse such Bank promptly upon its written request, for the amount of any Taxes so levied or imposed and paid by such Bank with respect to payments under this Agreement or under any Note. Notwithstanding anything contained herein, the Borrower and the Guarantors shall not be liable for any amount contemplated by this Section 4.5(a) to be paid by the Borrower or a Guarantor that shall arise more than 180 days prior to receipt by the Borrower of such written request.

(b) A Bank (and in the case of any assignment of an interest under this Agreement, such assignee) and/or Agent shall provide to the Borrower on the Effective Date and from time to time thereafter as requested by the Borrower, two (2) duly completed copies of United States Internal Revenue Service Form W-9, W-8IMY (with attachments, as applicable) W-8BEN or W-8ECI (or any subsequent replacement or substitute form thereof), as applicable. Each such Bank or Agent which so delivers Form W-9, W-8IMY, W-8BEN or W-8ECI further

Gerdau Credit Agreement

undertakes to deliver to the Borrower two (2) additional copies of such form (or successor form) on or before the date that such form expires or becomes obsolete or after the occurrence or any event requiring a change in the most recent form so delivered by it, and such amendments thereto or extensions or renewals thereof as may be reasonably requested by the Borrower, in each case, unless an event (including any change in law or regulation) has occurred prior to the date on which any such delivery would otherwise be required that renders all such forms inapplicable or that would prevent such Bank or Agent from duly completing and delivering any such form with respect to it. The Borrower shall not be required to pay any additional amounts pursuant to Section 4.5(a) to the extent the obligation to pay such additional amount would not have arisen but for the failure of the Bank or Agent to comply with this paragraph.

(c) Upon the reasonable written request of the Borrower, and at the Borrower’s expense, the Administrative Agent and each Bank shall use reasonable efforts to cooperate with the Borrower to obtain a refund of any Taxes which were not correctly or legally imposed and for which the Borrower or the Guarantors have indemnified such Administrative Agent or Bank under this Section 4.5, provided, however, the Administrative Agent or Bank shall not be obligated to provide the Borrower with any information on or justification of the arrangement of its tax affairs or otherwise disclose to the Borrower or any other Person any information the Administrative Agent or Bank considers to be proprietary or confidential. If the Administrative Agent or Bank shall receive a refund or a credit (other than a foreign tax credit) in lieu of such refund from a taxing authority of any Taxes paid by the Borrower pursuant to this Section, such Administrative Agent or Bank shall promptly pay to the Borrower the amount so received without interest (other than interest received from the taxing authority with respect to such refund) and net of out-of-pocket expenses, provided, however, upon the request of the Administrative Agent or Bank, the Borrower shall return the amount of such refund or credit to the Administrative Agent or Bank if the Administrative Agent or Bank is required to repay the amount of such refund or the benefit of such credit to the relevant authorities within six years of the date the Borrower are paid such amount by the Administrative Agent or Bank.

Section 4.6 Mitigation. If an event or circumstance occurs that would entitle a Bank to exercise any of the rights and benefits afforded by this Article IV, then, without in any way limiting, reducing or otherwise qualifying the rights of such Bank or the obligations of the Obligors hereunder, such Bank shall promptly upon becoming aware of such circumstances take steps as may be reasonably available to it (including a change of location of its Lending Office) to mitigate the effects of such event or circumstance, provided, however, that such Bank shall be under no obligation to take any step that, in its reasonable discretion, would (i) result in its incurring additional costs or taxes or (ii) otherwise be disadvantageous to such Bank.

Section 4.7 Replacement of Banks. Each Bank agrees that, upon the occurrence of any event giving rise to the operation of (a) Section 4.1 or Section 4.5 that results in the affected Bank charging to the Borrower increased costs or taxes in excess of the other Banks or (b) Section 4.3, then in each case the Borrower shall have the right, if no Default or Event of Default shall have occurred and be continuing, to cause such affected Bank to assign its Loans pursuant to Section 12.3 (with all fees payable pursuant to Section 12.3(b) to be paid by the replacement Bank(s)) to one or more Eligible Assignees; provided, that (i) such assignment shall not conflict and shall comply with Applicable Law, and (ii) the Borrower or such assignee shall have paid to the assigning Bank in immediately available funds an amount equal to the sum of the principal of

Gerdau Credit Agreement

and interest on the outstanding Loans of such Bank accrued to the effective date of such assignment, plus all fees and other amounts accrued for the account of such Bank hereunder (including, without limitation, any amounts under Article IV); provided, further, that, if prior to any such assignment the circumstances or event that resulted in such Bank’s notice under Section 4.1 or Section 4.3 or the amounts paid pursuant to Section 4.5, as the case may be, cease to cause such Bank to suffer increased costs or reductions in amounts received or receivable or reduction in return on capital, or cease to have the consequences specified in Section 4.3, or cease to result in amounts being payable under Section 4.5, as the case may be (including, without limitation, as a result of any action taken by such Bank pursuant to Section 4.6), or if such Bank shall waive its right to claim further compensation in excess of that being charged by the other Banks under Section 4.1 or shall waive its right to further payments in excess of that being charged by the other Banks under Section 4.5 in respect of such circumstances or event, as the case may be, then such Bank shall not thereafter be required to make any such assignment hereunder.

Gerdau Credit Agreement

that have been or will be prepared by any Obligor or its Affiliates and made available to any Joint Lead Arranger, the Administrative Agent or any Bank in connection with the Credit Documents or included therein or delivered pursuant thereto have been or will be prepared in good faith based upon assumptions that such Obligor believes to be reasonable at the time made and at the time made available to any Joint Lead Arranger, the Administrative Agent or any Bank.

None of the proceeds of the Loans or other extensions of credit under this Agreement will be used, directly or indirectly, for the purpose of purchasing or carrying any Margin Stock, for the purpose of reducing or retiring any Debt that was originally incurred to purchase or carry any Margin Stock or for any other purpose that might cause any portion of the Loans or other extensions of credit under this Agreement to be considered a “purpose credit” within the meaning of Regulations T, U or X of the Federal Reserve Board. No Obligor will take or permit to be taken any action by its Subsidiaries that might cause any Credit Document to violate any regulation of the Federal Reserve Board.

THE ADMINISTRATIVE AGENT

Section 11.1 Appointment, Powers and Immunities. (a) Each Bank hereby appoints and authorizes the Administrative Agent to act as its agent hereunder and (as applicable) under the other Credit Documents with such powers as are specifically delegated to the Administrative Agent by the terms of this Agreement and (as applicable) the other Credit Documents, together with such other powers as are reasonably incidental thereto. The Administrative Agent (which term as used in this sentence and in Section 11.5 shall include reference to its Affiliates and its own and its Affiliates’ officers, directors, employees, representatives and agents):

(i) shall have no duties or responsibilities except those expressly set forth in the Credit Documents and shall not by reason of this Agreement or any other Credit Document be a trustee or fiduciary for any Bank,

(ii) shall not be responsible to any Bank for any recitals, statements, representations or warranties contained in any Credit Document, or in any certificate or other document referred to or provided for in, or received by any of them under, any Credit Document, or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of any Credit Document or any other document referred to or provided for

Gerdau Credit Agreement

herein or for any failure by any Obligor to perform any of its obligations hereunder or thereunder,

(iii) except as expressly provided in the Credit Documents, shall not be required to initiate or conduct any litigation or collection proceedings under any Credit Document, and

(iv) shall not be responsible for any action taken or omitted to be taken by it hereunder or under any other document referred to or provided for herein or in connection herewith, except for its own gross negligence or willful misconduct.

The Administrative Agent may employ agents and attorneys-in-fact and shall not be responsible for the negligence or misconduct of or for the supervision of any such agents or attorneys-in-fact that were selected by it in good faith. The Administrative Agent shall as soon as practicable provide the Banks will all information and copies of all notices which are given to it and which by the terms of this Agreement are to be provided or given to the Banks.

(b) Before the Administrative Agent acts or refrains from acting, it may require an officer’s certificate from any Obligor and/or an opinion of counsel satisfactory to the Administrative Agent with respect to the proposed action or inaction at the Banks’ expense. The Administrative Agent shall not be liable for any action it takes or omits to take in good faith in reliance upon such certificate or opinion. Whenever in the administration of the Credit Documents the Administrative Agent shall deem it necessary or desirable that a matter be provided or established before taking or suffering or omitting to take any act under any Credit Document, such matter (unless other evidence in respect thereof is herein specifically prescribed) may, in the absence of gross negligence or bad faith on the part of the Administrative Agent, be deemed to be conclusively proved and established by an officers’ certificate delivered to the Administrative Agent, and such certificate, in the absence of gross negligence or bad faith on the part of the Administrative Agent, shall be full warrant to the Administrative Agent for any action taken, suffered or omitted to be taken by it under the Credit Documents upon the faith thereof.

(c) The Joint Lead Arrangers, in their capacities as joint lead arrangers, shall not have any liability or responsibility whatsoever under the Credit Documents.

(d) Any Person (i) into which the Administrative Agent may be merged or consolidated or (ii) that may result from any merger, conversion or consolidation to which the Administrative Agent shall be a party shall (if the Administrative Agent is not the surviving entity) be the successor of the Administrative Agent without the execution or filing of any instrument or any further act on the part of any of the parties hereto.

Section 11.2 Reliance by the Administrative Agent. The Administrative Agent shall be entitled to rely conclusively upon any certification, notice or other communication (including any thereof by e-mail, telephone or facsimile) reasonably believed by it to be genuine and correct and to have been signed or sent by or on behalf of the appropriate Person(s), and upon advice and statements of legal counsel and other experts selected by the Administrative Agent. As to any matters not expressly provided for in the Credit Documents, the Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, thereunder in accordance

Gerdau Credit Agreement

with instructions given by the Majority Banks, and such instructions of the Majority Banks and any action taken or failure to act pursuant thereto shall be binding upon all of the Banks.

Section 11.3 Defaults. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of a Default unless it has received written notice from a Bank or an Obligor specifying such Default and stating that such notice is a “Notice of Default.” If the Administrative Agent receives such a notice, then it shall give prompt notice thereof to the Banks and the Borrower (if such notice is received from a Bank). The Administrative Agent shall (subject to Section 11.7) take such action with respect to any such Default as shall be directed by the Majority Banks; provided that unless and until the Administrative Agent shall have received such directions, it may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable in the best interest of the Banks except to the extent that the Credit Documents expressly require that such action be taken, or not be taken, only with the consent or upon the authorization of the Majority Banks or all of the Banks.

Section 11.4 Rights as a Bank. With respect to any Commitment and Loan made or held by it, JPMorgan Chase Bank, N.A. (and any successor acting as an Agent) in its capacity as a Bank hereunder shall have the same rights and powers as any other Bank and may exercise the same as though it were not acting as the Administrative Agent, and the term “Bank” shall, unless the context otherwise indicates, include the Administrative Agent in its individual capacity. JPMorgan Chase Bank, N.A. (and any successor acting as an Agent) and its Affiliates may (without having to account therefore to any Bank) accept deposits from, lend money to, make investments in and generally engage in any kind of banking, trust or other business with any Obligor, and any Affiliate of any thereof as if it were not acting as the Administrative Agent, and JPMorgan Chase Bank, N.A. (and any such successor) and its Affiliates may accept fees and other consideration from any such Person(s) for services in connection with this Agreement or otherwise without having to account for the same to the Banks.

Section 11.5 Indemnification. The Banks agree to indemnify the Administrative Agent (to the extent not reimbursed under Section 12.1, but without limiting the obligations of the Obligors under Section 12.1) ratably in accordance with the aggregate principal amount of the Loans held by the Banks (or, if no Loans are at the time outstanding, ratably in accordance with their respective Commitments), for any and all losses, liabilities, claims, obligations, damages or expenses (including the fees and disbursements of counsel) incurred by it arising out of or by reason of any investigation in any way relating to or arising out of this Agreement or any other Credit Documents or the transactions contemplated hereby (including the costs and expenses that the Obligors are obligated to pay under Section 12.1, but excluding, other than additional administrative costs and expenses resulting from a Default, normal administrative costs and expenses incident to the performance of its agency duties hereunder) or the enforcement of any of the terms hereof or of any such other documents; provided that no Bank shall be liable to the Administrative Agent for any of the foregoing to the extent that it arises from the gross negligence or willful misconduct of the Administrative Agent as determined by a final, nonappealable judgment by a court of competent jurisdiction. In no event shall any Bank be liable to the Administrative Agent for any punitive or consequential damages in connection with any of the Credit Documents. The obligations of the Banks under this Section 11.5 shall

Gerdau Credit Agreement

survive the termination of this Agreement, the repayment of the Loans and/or the earlier resignation or removal of the Administrative Agent.

Section 11.6 Non-Reliance upon the Administrative Agent and other Banks. Each Bank agrees that it has, independently and without reliance upon the Administrative Agent, the Joint Lead Arrangers or any other Bank, and based upon such documents and information as it has deemed appropriate, made its own credit analysis of the Obligors and decision to enter into this Agreement and that it will, independently and without reliance upon the Administrative Agent, the Joint Lead Arrangers or any other Bank, and based upon such documents and information as it shall deem appropriate at the time, continue to make its own analysis and decisions in taking or not taking action under this Agreement and the other Credit Documents. The Administrative Agent shall not be required to inspect the Properties or books of any Obligor. Except for notices, reports and other documents and information expressly required to be furnished to the Banks by the Administrative Agent under the Credit Documents, the Administrative Agent shall not have any duty or responsibility to provide any Bank with any credit or other information concerning the affairs, financial condition or business of any Obligor that may come into the possession of the Administrative Agent or any of its Affiliates.

Section 11.7 Failure to Act. Except for any action expressly required of the Administrative Agent under a Credit Document, it shall in all cases be fully justified in failing or refusing to act under the Credit Documents unless it shall receive further assurances to its satisfaction from the Banks of their indemnification obligations under Section 11.5 against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. No provision of any Credit Document shall require the Administrative Agent to take any action that it reasonably believes to be contrary to Applicable Law or to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties thereunder or in the exercise of any of its rights or powers if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

Section 11.8 Resignation or Removal of the Administrative Agent. Subject to the appointment and acceptance of a successor Administrative Agent as provided below, the Administrative Agent may resign at any time by giving notice thereof to the Banks and the Obligors, and the Administrative Agent may be removed at any time with or without cause by the Majority Banks. Upon any such resignation or removal, the Majority Banks shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed and shall have accepted such appointment within 30 days after the existing Administrative Agent’s giving of notice of resignation or the Majority Banks’ election to remove such existing Administrative Agent, then such existing Administrative Agent may, on behalf of the Banks, appoint a successor Administrative Agent, which shall be a bank that has a combined capital and surplus of at least U.S.$100,000,000 (or its equivalent in any other currency). Upon the acceptance of any appointment as the Administrative Agent hereunder by a successor, such successor shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the existing Administrative Agent, and such existing Administrative Agent shall be discharged from its duties and obligations hereunder. After the Administrative Agent’s resignation or removal hereunder, the provisions of this Article shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as the Administrative Agent.

Section 12.1 Expenses; Indemnity.

(a) Whether or not the transactions contemplated hereby are consummated, the Borrower hereby agrees to pay or reimburse from time to time upon request: (i) the Administrative Agent for all of its reasonable and documented out-of-pocket costs and expenses (including the reasonable and documented fees and expenses of a single New York and local counsel (limited to single counsel in each applicable jurisdiction) to the Administrative Agent and Joint Lead Arrangers) in connection with: (A) the syndication, negotiation, preparation, review, translation, execution and delivery of this Agreement and the other Credit Documents and the documents and instruments prepared in connection herewith or in anticipation hereof (it being understood that the legal fees and other out-of-pocket expenses of the Joint Lead Arrangers and the Administrative Agent in connection with the items listed in this Clause (A) shall be limited to a total aggregate amount agreed upon by Gerdau and the Joint Lead Arrangers), and (B) the negotiation or preparation of any modification, amendment, supplement or waiver of any of the terms of this Agreement and the other Credit Documents (whether or not consummated) and (ii) the Agents and each of the Banks for all of their reasonable and documented out-of-pocket costs and expenses (including the reasonable and duly evidenced fees and expenses of shared legal counsel) in connection with any enforcement or collection proceedings resulting from the occurrence of an Event of Default. The Borrower further agrees to pay, and hold each of the Banks harmless from and against, any and all present and future stamp and other similar taxes with respect to this Agreement and the other Credit Documents and save and hold each of the Banks harmless from and against any and all liabilities with respect to or resulting from any delay or omission (other than to the extent attributable to such Banks) to pay such taxes.

To the extent that any undertaking in this

Gerdau Credit Agreement

Section may be unenforceable because it violates any Applicable Law or is contrary to public policy, the Obligors shall contribute the maximum portion that it is permitted to pay and satisfy under Applicable Law to the payment and satisfaction of such undertaking. In no event shall any party hereto be liable for punitive or consequential damages in connection with any of the Credit Documents.

(c) All amounts payable or indemnifiable under this Section shall be due and payable within four (4) Business Days after demand therefor. All amounts paid and costs incurred by any Indemnified Party in respect to any matter payable or indemnifiable under this Section shall, if not so paid or reimbursed by the Obligors before the date that is ten (10) Business Days after the date on which the Obligors were requested to make such payment, be an Event of Default and bear interest from the date of such request at the Default Rate. The obligations of the Obligors under this Section 12.1 shall survive the termination of this Agreement.

All such notices and communications shall, when mailed, facsimiled, or sent by overnight courier, be effective when received.

Section 12.3 Benefit of Agreement; Assignments and Participations.

(a) This Agreement shall be binding upon and inure to the benefit of and be enforceable by the respective successors and assigns of the parties hereto; provided, however, no Obligor may assign or transfer any of its rights, obligations or interest hereunder or under any other Credit Document without the prior written consent of each Bank.

(b) Each Bank may assign all or a portion of its Loans or Commitments hereunder to one or more Eligible Assignees each of which assignees shall become a party to this Agreement as a Bank by execution of an assignment agreement, substantially in the form of Exhibit E; provided that, (i) at such time Schedule I shall be deemed modified to reflect the Commitments of such new Bank and of the existing Banks; (ii) the Obligors will issue new Notes to such new Bank and to the assigning Bank upon the request of such new Bank or assigning Bank in replacement of the original Notes, such new Notes to be in conformity with the requirements of Section 2.4 to the extent needed to reflect the ownership of the Loans; (iii) the Administrative Agent shall receive at the time of each such assignment, from the assignee, the payment of a non-refundable assignment fee of U.S.$3,500; and (iv) each such assignment shall be in a minimum amount of U.S.$10,000,000. To the extent of any assignment pursuant to this Section 12.3(b), the assigning Bank shall be relieved of its obligations hereunder with respect to its assigned Commitments and Loans. No transfer or assignment under this Section 12.3(b) will be effective until recorded by the Administrative Agent on the Register pursuant to Section 12.3(c). Notwithstanding the foregoing, no assignment after Successful Syndication shall increase the withholding tax burden on the Borrower based on the Applicable

Gerdau Credit Agreement

Law in effect as of the date of such assignment, including, without limitation any additional amounts payable under Section 4.5(a); provided, however, that such limitation shall not prevent any such assignment, but shall shift the burden of any such increased cost, to the extent such cost relates solely to Applicable Law in effect as of the date of such assignment, to the relevant assignee throughout the remainder of the term of this Agreement.

(c) The Borrower hereby designate the Administrative Agent to serve as the Borrower’s agent, solely for purposes of this Section 12.3(c), to maintain a register (the “Register”) on which it will record the Commitments from time to time of each of the Banks, the Loans made by each of the Banks and each repayment in respect of the principal amount of the Loans of each Bank. The requirements of this Section 12.3(c) and Section 12.3(b) are intended to result in the Loans being in “registered form” for purposes of Section 871, Section 881 or any other applicable provision of the Code, and shall be interpreted and applied in a manner consistent therewith. Failure to make any such recordation, or any error in such recordation shall not affect the Borrower’s obligations in respect of the Loans. The Borrower agrees to indemnify the Administrative Agent from and against any and all losses, claims, damages and liabilities of whatsoever nature which may be imposed on, asserted against or incurred by the Administrative Agent in performing its duties under this Section 12.3(c), except to the extent that such losses, claims, damages or liabilities were caused by the gross negligence or willful misconduct of the Administrative Agent.

(d) Notwithstanding the foregoing, any Bank may transfer or grant participations in its rights hereunder without the consent of any Obligor. In connection with any such participation, such Bank shall remain a “Bank” for all purposes hereunder and the participant shall not constitute a “Bank” hereunder and no Bank shall transfer or grant any participation under which the participant shall have rights to approve any amendment to or waiver of this Agreement or any other Credit Document except to the extent such amendment or waiver would (i) extend the final scheduled maturity of any Loan or Note in which such participant is participating, or reduce the rate or extend the time of payment of interest or fees thereon (except in connection with a waiver of applicability of any post-default increase in interest rates) or reduce the principal amount thereof, or increase the Commitments in which such participant is participating over the amount thereof then in effect (it being understood that a waiver of any Default or Event of Default shall not constitute a change in the terms of any Commitment, and that an increase in any Commitment shall be permitted without the consent of any participant if the participant’s participation is not increased as a result thereof) or (ii) consent to the assignment or transfer by any Obligor of any of its rights and obligations under this Agreement. In the case of any such participation, the participant shall not have any rights under this Agreement or any of the other Credit Documents (the participant’s rights against such Bank in respect of such participation to be those set forth in the agreement executed by such Bank in favor of the participant relating thereto) and all amounts payable by the Borrower hereunder shall be determined as if such Bank had not sold such participation, except that the participant shall be entitled to the benefit of Article IV to the extent that such Bank would have been entitled thereto if it had not granted such participation.

(e) In addition to the assignments and participations permitted under the foregoing provisions of this Section 12.3, any Bank may (without notice or consent of the Administrative Agent, the Borrower or any other Person and without payment of any fee) assign

Gerdau Credit Agreement

and pledge all or any portion of its Loans and Notes to any U.S. Federal Reserve Bank as collateral security pursuant to Regulation A of the Board of Governors of the U.S. Federal Reserve System and any operating circular issued by such Federal Reserve Bank. No such assignment shall release the assigning Bank from its obligations hereunder.

Section 12.4 No Waiver; Remedies Cumulative. No failure or delay on the part of the Administrative Agent, any Joint Lead Arranger or any Bank or any holder of any Note in exercising any right, power or privilege hereunder or under any other Credit Document and no course of dealing among the Borrower and the Administrative Agent, any Joint Lead Arranger or any Bank or the holder of any Note shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder or under any other Credit Document preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder or thereunder. The rights, powers and remedies herein or in any other Credit Document expressly provided are cumulative and not exclusive of any rights, powers or remedies which the Administrative Agent, any Joint Lead Arranger or any Bank or the holder of any Note would otherwise have. No notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the Administrative Agent, any Joint Lead Arranger or any Bank or the holder of any Note to any other or further action in any circumstances without notice or demand.

Section 12.5 Calculations; Computations.

(a) The financial statements to be furnished to the Banks pursuant hereto shall be made and prepared in accordance with GAAP (except as set forth in the notes thereto or as otherwise disclosed in writing by any Obligor to the Banks); provided that, except as otherwise specifically provided herein, all computations determining compliance with Sections 8.13 and 8.14, including the definitions used therein, shall utilize accounting principles and policies in conformity with those used to prepare the historical financial statements delivered to the Banks pursuant to Section 5.7, except to the extent such principles and policies are required by Applicable Law to be changed.

(b) All computations of interest and the Fees hereunder shall be made on the basis of a year of 360 days for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or Fees are payable.

Section 12.6 Governing Law; Submission To Jurisdiction; Venue.

(a) This Agreement and the other Credit Documents and the rights and obligations of the parties hereunder and thereunder shall be governed by and construed in accordance with the law of the State of New York.

(b) Any legal action or proceeding with respect to this Agreement or any other Credit Document may be brought in the courts of the State of New York or of the United States for the Southern District of New York sitting in the Borough of Manhattan, New York City, and, by execution and delivery of this agreement, each party hereto hereby

Gerdau Credit Agreement

irrevocably accepts, for the benefit of each other party hereto, for itself and in respect of its property, generally and unconditionally, the non-exclusive jurisdiction of the aforesaid courts.

(c) Each Obligor hereby irrevocably designates, appoints and empowers Law Debenture Corporate Services, Inc. with offices currently located at 400 Madison Avenue, 4th Floor, New York, New York 10017, United States of America (the “Process Agent”) as its designee, appointee and agent to receive, accept and acknowledge for and on its behalf, and in respect of its property, service of any and all legal process, summons, notices and documents which may be served in any such action or proceeding brought in any courts of the State of New York or of the United States for the Southern District of New York. Each Obligor covenants and agrees that it shall take any and all reasonable action, including the execution and filing of any and all documents that may be necessary to continue the foregoing appointment in full force and effect and to cause the agent for service of process to continue to act in such capacity. If for any reason the Law Debenture Corporate Services, Inc. (or any successor thereto) shall cease, or shall not be capable to act, as process agent, the Obligors shall promptly and irrevocably designate and appoint a successor process agent, subject to the Administrative Agent’s reasonable approval. In the event that the Obligors have not duly appointed such successor process agent within 15 days after the existing process agent ceases to act as such, the Obligors hereby authorize the Administrative Agent to act as the Obligors’ duly appointed attorney-in-fact to execute any documents and take any actions reasonably necessary for the Administrative Agent to appoint a successor process agent and shall promptly provide notice of such appointment to the Obligors. Each Obligor further irrevocably consents to the service of process out of any of the aforementioned courts in any such action or proceeding by the mailing of copies thereof, to the extent permitted under applicable law, by registered or certified mail, postage prepaid, to such Obligor at its address set forth opposite its signature below, such service to become effective upon receipt. It is hereby agreed by the parties hereto that the preferred method of service of process shall be through process served on the Process Agent, and alternative methods shall be used only if such service of process through the Process Agent is determined to be invalid, ineffective, untimely or otherwise burdensome as determined by the Administrative Agent or the Majority Banks in their sole discretion. Nothing herein shall affect the right of any Obligor, the Administrative Agent, any Joint Lead Arranger, any Bank or the holder of any Note to serve process in any other manner permitted by law or to commence legal proceedings or otherwise proceed against any other party hereto in any other jurisdiction.

(d) Each of the Obligors hereby irrevocably waives any objection which it may now or hereafter have to the laying of venue of any of the aforesaid actions or proceedings arising out of or in connection with this agreement or any other credit document brought in the courts referred to in clause (b) above and hereby further irrevocably waives and agrees not to plead or claim in any such court that any such action or proceeding brought in any such court has been brought in an inconvenient forum.

Gerdau Credit Agreement

Section 12.8 Counterparts; Headings Descriptive; English Language. This Agreement may be executed in any number of counterparts and by the different parties hereto on separate counterparts, each of which when so executed and delivered shall be an original, but all of which shall together constitute one and the same instrument. The headings of the several sections and subsections of this Agreement are inserted for convenience only and shall not in any way affect the meaning or construction of any provision of this Agreement. All documents to be delivered by any party hereto pursuant to the terms of this Agreement or any other Credit Documents and all certificates, reports or notices to be delivered or communications to be given or made by any party hereto pursuant to the terms of this Agreement or any other Credit Document shall be in the English language or, if originally written in another language, shall be accompanied by an accurate English translation upon which the other parties hereto shall have the right to rely for all purposes of this Agreement and the other Credit Documents.

Section 12.9 Amendment or Waiver. Neither this Agreement nor any other Credit Document nor any terms hereof or thereof may be changed, waived, discharged or terminated unless such change, waiver, discharge or termination is in writing signed by the Borrower and the Majority Banks; provided that no such change, waiver, discharge or termination shall, without the consent of each Bank being directly affected thereby: (i) extend the final scheduled maturity of any Loan or any Note, or reduce the rate or extend the time of payment of interest or Fees thereon (except in connection with a waiver of applicability of any post-default increase in interest rates), or reduce the principal amount thereof, or increase (over the amount thereof then in effect) or extend the availability of (whether by amendment of the definition of Availability Expiry Date or otherwise) the Commitments of any Bank (it being understood that a waiver of any conditions precedent, covenants, Default or Event of Default shall not constitute an increase or extension of the availability of the Commitment of any Bank); (ii) amend, modify or waive any provision of this Section 12.9; (iii) reduce the percentage specified in, or otherwise modify, the definition of Majority Banks; (iv) consent to the assignment or transfer by or release of any Obligor of any of its rights and obligations under this Agreement; or (v) amend, modify or waive any provision in Article X hereof or release any Guarantor from any of their respective obligations hereunder; provided further, that no such change, waiver, discharge or termination shall: (x) without the consent of the Agents, amend, modify or waive any provision of Article XI or any other provision relating to the rights or obligations of the Agents, or (y) without the consent of the Joint Lead Arrangers, amend, modify or waive any provision relating to the rights of the Joint Lead Arrangers.

Section 12.10 Survival. All indemnities set forth herein including, without limitation, in Article IV, Sections 10.3, 11.5, 12.1, 12.3 and 12.11 shall survive the execution and delivery of this Agreement and the Notes and the making and repayment of the Loan and any assignments thereof.

Section 12.11 Judgment Currency. The obligations of the Obligors hereunder and under the other Credit Documents to make payments in Dollars shall not be discharged or satisfied by any tender or recovery pursuant to any judgment expressed in or converted into any currency other than Dollars, except to the extent that such tender or recovery results in the effective receipt by an Agent or the respective Bank of the full amount of Dollars expressed to be payable to such Agent or such Bank under this Agreement or the other Credit Documents. Each Obligor agrees to indemnify the Agents and each Bank against any loss incurred by such Agent

Gerdau Credit Agreement

or such Bank as a result of any judgment or order being given or made for the payment of any amount due hereunder or under any other Credit Document which is expressed and paid in a currency other than Dollars (such other currency, the “Judgment Currency”) and as a result of any variation between (a) the rate of exchange at which the Dollar amount is converted into the Judgment Currency for the purposes of such judgment or order, and (b) the rate of exchange at which such Agent or such Bank is able to purchase Dollars with the amount of Judgment Currency actually received by such Agent or such Bank. The foregoing indemnity shall, to the extent permitted by Applicable Law, constitute a separate and independent obligation of the Obligors, shall continue in full force and effect notwithstanding any such judgment or order as aforesaid, and shall not be affected by judgment being obtained for any other sums due under this Agreement or under any other Credit Document. The term “rate of exchange” shall include any premiums and costs payable in connection with the purchase of, or conversion into, the relevant currency.

Section 12.12 Waiver of Sovereign Immunity. Each Obligor represents, warrants and agrees that the activities contemplated by the provisions of the Credit Documents are commercial in nature rather than governmental or public, and therefore represents, warrants and agrees that it is not entitled to any right of immunity on the grounds of sovereignty or otherwise with respect to such activities or in any legal action or proceeding arising out of or relating to the Credit Documents. Each Obligor, in respect of itself and its properties and revenues, hereby expressly irrevocably waives, to the extent permitted by Applicable Law, any right of immunity that such Obligor or any of its properties and revenues has or may hereafter acquire, whether characterized as sovereign immunity or otherwise, from any legal proceedings, whether in the United States, the Cayman Islands, Brazil or elsewhere, related to or arising from the transactions contemplated by any of the Credit Documents, and agrees not to assert any such right or claim in any such proceeding.

Section 12.13 Confidentiality. Each Bank agrees to keep confidential (other than (x) with respect to its employees, auditors, accountants, advisors or counsel or to another Bank if the Bank or such Bank’s holding or parent company in its sole discretion determines that any such party should have access to such information, provided such Persons shall be subject to the provisions of this Section 12.13 to the same extent as such Bank or (y) with the prior consent of any Obligor), in accordance with its customary procedures of handling confidential information of the same nature and in accordance with safe and sound banking practices, any information with respect to the Obligors or any of their Subsidiaries which has been, is now or in the future will be furnished pursuant to or in anticipation of this Agreement or any other Credit Document and which is designated by the Obligors to the Banks in writing as confidential or would customarily be treated as confidential in banking practice, provided that any Bank may disclose any such information (i) as has become generally available to the public, (ii) as may be required or appropriate in any report, statement or testimony submitted to any Governmental Authority having or claiming to have jurisdiction over such Bank, (iii) as may be required or appropriate in respect to any summons or subpoena or in connection with any litigation, (iv) in order to comply with any Applicable Law applicable to such Bank, (v) to the Administrative Agent, (vi) to any credit rating agency that rates the financial condition of the Bank or the claims paying ability of the Bank or the financial condition of the Obligors, (vii) to any prospective or actual transferee or participant (or its investment or legal advisors) in connection with any contemplated transfer or participation of any of the Loans, Notes or Commitments or any interest therein by such Bank,

Gerdau Credit Agreement

provided that such prospective transferee agrees to maintain the confidentiality contained in this Section 12.13 and, in the case of any Projections, agrees to sign a confidentiality agreement in form and substance reasonably satisfactory to Gerdau and Ameristeel, (viii) to any prospective or actual counterparty (or its investment or legal advisors) in connection with any securitization, swap or derivative transactions relating to any Obligor, any Subsidiary of an Obligor, and/or the Obligations, provided that prior written notice identifying the prospective or actual counterparty is given to the Borrower and such prospective counterparty agrees to maintain the confidentiality contained in this Section 12.13 and, in the case of any Projections, agrees to sign a confidentiality agreement in form and substance reasonably satisfactory to Gerdau and Ameristeel, and (ix) to any of its Affiliates in connection with the administration, syndication or enforcement of the Credit Documents.

The Obligors agree that the terms contained in the Credit Documents are confidential and, except for disclosure to the various parties thereto, their respective shareholders and such Persons’ board of directors (or similar body), officers, employees or professional advisors, or as may be compelled in a judicial or administrative proceeding or otherwise be required by Applicable Law, may not be disclosed in whole or in part by any Obligor to any other Person without the prior written consent of the Administrative Agent.

Section 12.14 USA PATRIOT Act Notice. Each Bank subject to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”) and each of the Agents (for itself and not on behalf of any Bank), hereby notifies the Borrower that pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other reasonable information that will allow such Bank or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Patriot Act.

Local supplying is performed by several sub-suppliers and therefore they were not named. Furthermore, because of the nature of BNDES contracts, the pledge of equipment is not performed by a single contract, but by several, depending on the structure of purchasing and financing. What was done here was to aggregate the different amounts into a single one under each project. However it does not mean that the entire equipment was given as guarantee.

Litigation related: In addition: various judicial deposits made in connection with pending litigation.

Securitization: Liens under the documentation for the Secured Export Notes.
