(c) Together with the delivery of a Change of Control Notice by the Borrowers and Gerdau, GNA Partners will irrevocably offer to prepay the outstanding principal balance of the Tranche B Loans plus accrued interest thereon, plus any amounts payable pursuant to Section 4.4 with respect thereto with the date of such prepayment to be the date occurring five (5) Business Days following the delivery of an Exercise Notice in accordance with subsection (b) above. If no Exercise Notice is delivered in accordance with subsection (b) above, GNA Partners’ irrevocable offer to prepay the Tranche B Loans shall lapse. If the Exercise Notice is delivered in accordance with subsection (b) above, then the delivery of such Exercise Notice shall be deemed to be an acceptance of GNA Partners’ offer to prepay and GNA Partners shall prepay the Tranche B Loans on the date occurring five (5) Business Days following the delivery of the Exercise Notice.

(d) Nothing in subsection (c) above limits or otherwise affects the obligations of either Borrower under subsection (b) above or pursuant to Section 2.1(d).

Section 2.9 Interest.

(a) The Borrowers agree to pay interest in respect of the outstanding principal amount of each Loan made to the Borrowers from, and including, the date of the Borrowing thereof to, but excluding, the date such Loan is paid in full, at a rate per annum which shall at all times be equal to the sum of the LIBO Rate plus the Applicable Margin. Accrued (and theretofore unpaid) interest shall be payable (i) in arrears on each Interest Payment Date, (ii) on the date of any prepayment (on the amount prepaid), and (iii) at maturity (whether by acceleration or otherwise) and, after such maturity, on demand.

(b) Notwithstanding anything herein to the contrary, at any time following the occurrence and during the continuance of an Event of Default under Section 10.1 (including, without limitation, a failure to pay when due amounts declared due and payable in accordance with Article X following an Event of Default) all amounts then due (including, without limitation and to the extent permitted by Applicable Law, overdue interest in respect of each Loan) shall, in each case, bear interest at the Default Rate and such Default Rate shall be fixed for Interest Periods of such duration as shall be selected by the Administrative Agent which Interest Periods shall not be longer than one (1) month. Interest which accrues under this Section 2.9(b) shall be payable on demand.

(c) Upon each Interest Determination Date, the Administrative Agent shall determine the LIBO Rate and shall promptly notify the Borrowers and the Banks thereof. Each such determination shall, absent manifest error, be final and conclusive and binding on all parties hereto.

(d) If S&P publicly announces a change in the Rating of Gerdau, the Applicable Margin due for the Interest Period for any Loan during which the rating change occurred shall be calculated by the Administrative Agent on a pro rata basis according to the definition of Applicable Margin and based on the number of days during such Interest Period that the original Rating was in effect and the number of days during such Interest Period that the new Rating was in effect.

Section 2.10 Method and Place of Payment. Except as otherwise specifically provided herein, all payments under this Agreement or any Note shall be made without setoff, counterclaim or other defense to the Administrative Agent for the account of the Bank or Banks entitled thereto not later than 1:00 p.m. (New York time) on the date when due (and any payments received after such time shall be deemed received on the next succeeding Business Day) and shall be made in Dollars in immediately available funds to the Administrative Agent’s Account at the Payment Office of the Administrative Agent. Whenever any payment to be made hereunder or under any Note shall be stated to be due on a day which is not a Business Day, the due date thereof shall be extended to the next succeeding Business Day and, with respect to payments of principal, interest shall be payable at the applicable rate during such extension; provided, however, that if there are no succeeding Business Days in such calendar month, such payment shall be due on the next preceding Business Day. Any payment made to the Administrative Agent in accordance with this Section 2.10 for account of a Bank or Banks shall be deemed to have been a payment made directly to such Bank or Banks solely for the purpose of evidencing satisfaction of the applicable payment obligation by the Borrowers hereunder or under any Note, as the case may be.

Section 2.11 Payments Pro Rata. The Administrative Agent agrees that promptly after its receipt of each payment or prepayment from or on behalf of the Borrowers in respect of any Obligations hereunder, it shall distribute such payment to the Banks pro rata based upon their respective shares, if any, of the Obligations with respect to which such payment was received (other than payments made pursuant to Sections 4.1, 4.4 or 4.5 hereof, which shall be distributed pro rata based upon claims made by the Banks under such Sections).

Section 2.12 Set-Off; Sharing of Payments; Reinstatement.

(a) Without limiting any of the obligations of the Obligors or the rights of any Bank under the Credit Documents, if an Event of Default exists pursuant to Section 10.1 of this Agreement, then (to the extent not in violation of Applicable Law) each Bank may, without prior notice to the Obligors (which notice is expressly waived by it to the fullest extent permitted by Applicable Law), set-off and apply against such amount any and all cash deposits (general or special, time or demand, provisional or final, in any currency, matured or unmatured) then held or any other Debt owing by such Bank or any of its Affiliates (in each case, including any branch or agency thereof) to or for the credit or account of any Obligor. 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.

(b) Each of the Banks agrees that, if it should receive any amount in payment of any Obligations owing to it under the Credit Documents (whether by voluntary payment, by realization upon security, by the exercise of the right of setoff or banker’s lien, by 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 Borrowers 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 September 10, 2007 with respect to Original Banks and at any time on or after the date hereof with respect to each other Bank), 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 Borrowers 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 Borrowers shall not be liable for any amount contemplated by this Section 4.1(a) to be paid by the Borrowers that shall arise more than 180 days prior to receipt by the Borrowers 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 September 10, 2007 with respect to Original Banks and at any time on or after the date hereof with respect to each other Bank), 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 Borrowers, 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 Borrowers (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 Borrowers (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 and allocations are made on a reasonable basis and are mathematically accurate. Such amounts shall be payable by the Borrowers 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 Borrowers shall not preclude the Borrowers from contesting such calculation in accordance with the terms of this Agreement. Notwithstanding anything contained herein, the Borrowers shall not be liable for any amount contemplated by this Section 4.1(b) to be paid by the Borrowers that shall arise more than 180 days prior to receipt by the Borrowers 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 Borrowers and to the Administrative Agent of such determination (which notice the Administrative Agent shall promptly transmit to each of the other Banks), and the Borrowers 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 Borrowers 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 Borrowers shall not be liable for any amounts contemplated by this Section 4.1(c) to be paid by the Borrowers that shall arise more than 180 days prior to receipt by the Borrowers of such written notice or demand. Each Bank agrees that if it gives notice to the Borrowers of the existence of a Eurocurrency Reserve Period, it shall promptly notify the Borrowers of any termination thereof, at which time the Borrowers 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 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 Borrowers and shall apply in lieu of the LIBO Rate for such Interest Period (such certification to be conclusive and binding on the Borrowers 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 above, at any time on or after September 10, 2007 with respect to Original Banks and at any time on or after the date hereof with respect to each other Bank) 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 Borrowers 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 Borrowers, together with accrued and unpaid interest thereon and all other amounts payable to such Bank by the Borrowers 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 Borrowers 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 Borrowers 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 Borrowers 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 Notices 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 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 Borrowers) 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 Borrowers.

Section 4.5 Taxes.

(a) All payments made by or on behalf of the Borrowers 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 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 13.3(b), if any Taxes are so levied or imposed, each of the Borrowers 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 Borrowers or such Guarantor, as applicable, will promptly (and in no event more than three Business Days after receipt of such request) furnish to the Administrative Agent

and any applicable Bank original tax receipts, notarized copies of tax receipts, a copy of the return (including, without limitation, United States Internal Revenue Service Form 1042-S or any successor form) reporting the payment of such Taxes and such other documentation as reasonably requested to prove payment of tax, for all Taxes paid by the Borrowers or such Guarantor, as applicable, pursuant to this Section 4.5. Each of the Borrowers 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 Borrowers and the Guarantors shall not be liable for any amount contemplated by this Section 4.5(a) to be paid by the Borrowers or a Guarantor that shall arise more than 180 days prior to receipt by the Borrowers 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 Borrowers on or before the date hereof (unless previously provided to the Borrowers in connection with the Original Agreement) and from time to time thereafter as requested by the Borrowers, 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 undertakes to deliver to the Borrowers 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 Borrowers, 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 Borrowers 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 Borrowers, and at the Borrowers’ expense, the Administrative Agent and each Bank shall use reasonable efforts to cooperate with the Borrowers to obtain a refund of any Taxes which were not correctly or legally imposed and for which the Borrowers 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 Borrowers with any information on or justification of the arrangement of its tax affairs or otherwise disclose to the Borrowers 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 Borrowers pursuant to this Section, such Administrative Agent or Bank shall promptly pay to the Borrowers 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 Borrowers 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 Borrowers are paid such amount by the Administrative Agent or Bank.

Section 4.6 Mitigation. If an event or circumstance occurs after the date hereof 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 occurring after the date hereof giving rise to the operation of (a) Section 4.1 or Section 4.5 that results in the affected Bank charging to the Borrowers increased costs or taxes in excess of the other Banks or (b) Section 4.3, then in each case the Borrowers 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 13.3 (with all fees payable pursuant to Section 13.3(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 Borrowers or such assignee shall have paid to the assigning Bank in immediately available funds an amount equal to the sum of the principal of 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.

All financial projections (the “Projections”), if any, 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.

No ERISA Event has occurred or, to the knowledge of the Obligors, is reasonably expected to occur that, when taken together with all other such ERISA Events for which liability is reasonably expected to occur, could reasonably be expected to result in a Material Adverse Effect.

In the event that at any time during the term of this Agreement the Intercompany Export Agreement no longer satisfies the requirements of the preceding sentence as a result of fluctuations in the Market Value of the Products or otherwise, the Exporters and the Off-taker will amend the Intercompany Export Agreement to ensure compliance therewith.

(b) The Off-taker will ensure (i) at all times that it has designated adequate Eligible Buyers as Designated Eligible Buyers pursuant to the terms hereof so that, commencing October 15, 2007, sales to such Designated Eligible Buyers are scheduled to generate export receivables payable to the Off-taker (“Export Receivables”) in amounts adequate to satisfy the Periodic Coverage Ratio for each Interest Period, and (ii) all such Export Receivables shall be Springing Lien Collateral.

(c) In the event that at any time during the term of this Agreement the Export Receivables generated from sales to Designated Eligible Buyers are not adequate to satisfy the requirements of Section 8.15(b), Gerdau and the Off-taker will promptly designate additional Eligible Buyers as Designated Eligible Buyers and all Export Receivables to be generated from sales to such Designated Eligible Buyers as Springing Lien Collateral as needed to generate the Export Receivables up to the Periodic Coverage Amount by attaching to a Compliance Certificate a revised Schedule IV to this Agreement, and upon the Collateral Agent’s receipt of any Compliance Certificate attaching a revised Schedule IV, Schedule IV hereof shall be automatically amended to include such Eligible Buyers that have been designated as additional Designated Eligible Buyers provided such additional Designated Eligible Buyers satisfy all applicable conditions specified herein; provided further, that if such failure to satisfy the requirements of Section 8.15(b) results from the ineligibility of a Designated Eligible Buyer due to the restrictions referred to in the definition of “Eligible Buyers”, either (i) Gerdau and the Off-taker shall, within 10 days after notice thereof from any Bank, the Administrative Agent or

the Collateral Agent, replace such Designated Eligible Buyer and make the designations necessary to satisfy the requirements of Section 8.15(b) or (ii) the Borrowers shall, within 60 days after notice thereof from any Bank, the Administrative Agent or the Collateral Agent, prepay the Pre-Export Loans in accordance with Section 2.7 by an amount necessary so that the Off-taker is in full compliance with Section 8.15(b); provided further that in the event any Bank, the Administrative Agent or the Collateral Agent sends such a notice to the Off-taker with respect to any Designated Eligible Buyer after the occurrence of an Activation Event, the Off-taker and the Collateral Agent shall immediately instruct such Designated Eligible Buyer to make any future payments to an account designated by the Off-taker that is not the Collection Account and, upon the receipt of any such funds, the Off-taker shall immediately transfer an amount equal thereto from the Off-taker’s Payment Account to the Collection Account (such funds to be derived from other export receivables of the Off-taker).

(d) Unless and until an Activation Event occurs, the Off-taker shall irrevocably instruct the Designated Eligible Buyers to make all payments in respect of Export Receivables to the Off-taker’s Payment Account.

(e) The Exporters and the Off-taker will not create, assume or suffer to exist any Lien in or on any of the Springing Lien Collateral as it may exist from time to time other than any Lien created under the Credit Documents.

(f) Gerdau shall provide the Collateral Agent (i) no later than the date occurring 10 days after the last day of each Interest Period, a compliance certificate (each, a “Compliance Certificate”), substantially in the form of Exhibit G hereto, certifying, (x) with respect to such Interest Period, the amount of Export Receivables generated from sales of Products to Designated Eligible Buyers during such Interest Period and confirming that the Periodic Coverage Amount applicable to such Interest Period is generated specifically from Export Receivables derived from sales of Products to Designated Eligible Buyers, and (y) that based on current Market Values the Intercompany Export Agreement currently provides for sales of sufficient Products to satisfy the Overall Coverage Amount test specified in subsection (a) above; (ii) at the time of delivery of each Compliance Certificate and prior to an Activation Event, a letter (or similar document) from JPMorgan Chase Bank, N.A. certifying as to the total amount credited to the Off-taker’s Payment Account during such Interest Period; and (iii) on the Effective Date and on each anniversary of the Effective Date, a written report in form reasonably satisfactory to the Collateral Agent evidencing historical aggregate revenues from each Designated Eligible Buyer for the preceding three-year period, together with a non-binding projection of anticipated revenues for each such Designated Eligible Buyer for the then upcoming annual period.

ARTICLE IX

TRIGGER EVENT AND ACTIVATION EVENT

Section 9.1 Trigger Event. The parties hereby agree that a “Trigger Event” shall occur if the Off-taker shall fail to generate the Periodic Coverage Amount with respect to an Interest Period from Export Receivables for any two consecutive Interest Periods or for any three non-consecutive Interest Periods during the term of this Agreement. Any subsequent failure to

generate the Periodic Coverage Amount with respect to any Interest Period from Export Receivables after the occurrence of a Trigger Event shall constitute an Event of Default.

Section 9.2 Activation Event. Upon the occurrence of a Trigger Event or an Event of Default, the Administrative Agent may, or upon the written direction of the Majority Banks shall, declare the activation of the lien on the Springing Lien Collateral (such declaration, an “Activation Event”).

Section 9.3 Consequences of Activation Event. Upon the occurrence of an Activation Event, the following shall occur:

(a) The Off-taker shall promptly, but no later than four (4) Business Days after the occurrence of an Activation Event, send notices (each, a “Designated Eligible Buyer Notice”), substantially in the form set forth in Exhibit E hereto, to each Designated Eligible Buyer, with a copy of each Designated Eligible Buyer Notice being sent by the Off-taker to the Collateral Agent, informing each Designated Eligible Buyer of the Off-taker’s and applicable Exporter’s assignment of their respective rights to all Export Receivables and irrevocably instructing such Designated Eligible Buyer to make all payments in respect of Export Receivables to the Collection Account, and if the Off-taker fails to send any such Designated Eligible Buyer Notices, the Collateral Agent may send such Designated Eligible Buyer Notices directly. The Off-Taker shall use its reasonable best efforts to obtain the acknowledgment of each Designated Eligible Buyer to its Designated Eligible Buyer Notice. All invoices sent to each Designated Eligible Buyer after the occurrence of an Activation Event shall contain irrevocable payment instructions directing that all payments thereunder be made to the Collection Account.

(b) The Exporters and/or Off-taker shall promptly, but no later than one (1) Business Day after the occurrence of an Activation Event, cause the transfer of any future payments of Export Receivables by Designated Eligible Buyers received in the Off-taker’s Payment Account from the Off-taker’s Payment Account to the Collection Account promptly upon receipt thereof.

(c) During each Interest Period, if an Activation Event is declared as a result of the occurrence of a Trigger Event, the Collateral Agent will retain in the Collection Account one-fifth of the Pre-Export Loans Debt Service Amount due at the end of such Interest Period in each of the first five months of such Interest Period so that the full amount of the Pre-Export Loans Debt Service Amount will be on deposit in the Collection Account thirty (30) days prior to the end of such Interest Period. If such Pre-Export Loans Debt Service Amount has not been deposited into the Collection Account by such date, then the Collateral Agent shall notify the Off-taker of such shortfall on or before the date occurring five (5) Business Days prior to the applicable Payment Date. In the event of any such shortfall, the Off-taker shall transfer an amount equal to the shortfall from the Off-taker’s Payment Account to the Collection Account (such funds to be derived from other export receivables of the Exporters and/or Off-taker) before the date occurring two (2) Business Days prior to the applicable Payment Date.

(d) During each Interest Period, if an Activation Event is declared as a result of the occurrence of an Event of Default or if an Event of Default shall have otherwise

occurred and be continuing, the Collateral Agent shall retain all amounts deposited into the Collection Account for application towards the repayment of the Borrowers’ obligations hereunder; provided however, that such amounts shall be retained only until funds in the Collection Account equal the Pre-Export Loans Debt Service Amount applicable to such Interest Period, unless the unpaid principal amount of the Loans has been accelerated in accordance with Article X, in which case all amounts deposited in the Collection Account shall be retained and applied as repayment of the Borrowers’ obligations hereunder. The Off-taker agrees that the full amount of the Pre-Export Loans Debt Service Amount applicable to such Interest Period will be on deposit in the Collection Account thirty (30) days prior to the end of such Interest Period. If such Pre-Export Loans Debt Service Amount has not been deposited into the Collection Account by such date, then the Collateral Agent shall notify the Off-taker of such shortfall and the Off-taker shall transfer an amount equal to the shortfall from the Off-taker’s Payment Account to the Collection Account (such funds to be derived from other export receivables of the Exporters and/or Off-taker) within two (2) Business Days of the date it receives notice from the Collateral Agent of such shortfall.

(e) If no Event of Default shall have occurred and be continuing and the Borrowers shall have duly paid the applicable Pre-Export Loans Debt Service Amount in full on a Payment Date, then on the Business Day following receipt of such payment, the Collateral Agent shall release any amounts in the Collection Account to the Off-taker.

Section 9.4 Trigger Event Mandatory Prepayment. If during any Interest Period after the declaration of an Activation Event (a) the transfer required to be made by Gerdau in accordance with either Sections 9.3(c) or 9.3(d) above is not received in the Collection Account before the applicable date specified in such subsection, or (b) upon any subsequent failure to generate the Periodic Coverage Amount, the Collateral Agent shall be entitled to retain all amounts deposited in the Collection Account during such Interest Period for application towards the pro rata prepayment of the Borrowers’ obligations under the Pre-Export Loans on the next succeeding Payment Date; provided that in the case of subsection (b) only, the amount to be applied toward such prepayment shall equal the difference between the Periodic Coverage Amount and the amount actually received in the Collection Account during such Interest Period and any excess funds in the Collection Account shall be released to the Off-taker.

Section 9.5 OFAC Payments. The Collateral Agent, acting in its sole discretion, shall be entitled to block, suspend or reject payments made to the Collection Account if it has reason to believe that such payments are from any Person named on an OFAC List or related to sales of Products received by any Person named on an OFAC List.

Section 11.2 Guaranty Unconditional. The obligations of the Guarantors under this Article XI shall be unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged or otherwise affected by:

(a) any extension, renewal, settlement, compromise, waiver or release in respect of any obligation(s) of the Borrowers under the Credit Documents and/or any Commitment(s) under the Credit Documents, by operation of law or otherwise,

(b) any modification or amendment of or supplement to this Agreement or any other Credit Document,

(c) any change in the corporate existence, structure or ownership of the Borrowers or any other Person, or any event of the type described in Section 10.5 with respect to any Person,

(d) the existence of any claim, set-off or other rights that any Guarantor may have at any time against the Borrowers, the Administrative Agent, any Bank or any other Person, whether in connection herewith or with any unrelated transactions,

(e) any invalidity or unenforceability relating to or against the Borrowers for any reason of any Credit Document, or any provision of Applicable Law purporting to prohibit the performance by the Borrowers of any of their obligations under the Credit Documents, or

(f) any other act or omission to act or delay of any kind by the Borrowers, the Administrative Agent, any Bank or any other Person or any other circumstance whatsoever that might, but for the provisions of this Section, constitute a legal or equitable discharge of the obligations of the Borrowers under the Credit Documents.

Section 11.3 Discharge Only Upon Payment in Full; Reinstatement In Certain Circumstances. The obligations of the Guarantors hereunder shall remain in full force and effect until all of the payment obligations of the Borrowers under the Credit Documents shall have been paid or otherwise performed in full and all of the Commitments shall have terminated. If at any time any payment made under this Agreement or any other Credit Document is rescinded or must otherwise be restored or returned upon the insolvency, bankruptcy, reorganization, recuperação judicial ou extrajudicial, falência or similar event of the Borrowers or any other Person or otherwise, then the obligations of the Guarantors hereunder with respect to such payment shall be reinstated at such time as though such payment had been due but not made at such time.

Section 11.4 Waiver. Each Guarantor hereby irrevocably and unconditionally waives, to the fullest extent permitted by Applicable Law: (a) notice of acceptance of the Guaranty provided in this Article XI and notice of any liability to which this Guaranty may apply; (b) all notices that may be required by Applicable Law or otherwise to preserve intact any rights of any Bank against the Borrowers, including any demand, presentment, protest, proof of notice of non-payment, notice of any failure on the part of the Borrowers to perform and comply with any covenant, agreement, term, condition or provision of any agreement and any other notice to any other party that may be liable in respect of the obligations Guaranteed hereby (including the Borrowers) except any of the foregoing as may be expressly required hereunder; (c) any right to the enforcement, assertion or exercise by the Administrative Agent or any Bank of any right, power, privilege or remedy conferred upon such Person under the Credit Documents or otherwise; (d) any requirement that the Administrative Agent or any Bank exhaust any right, power, privilege or remedy, or mitigate any damages resulting from a default, under any Credit Document, or proceed to take any action against the Borrowers or any other Person under or in respect of any Credit Document or otherwise; and (e) the benefit of Articles 827, 829, 830, 834, 835, 837, 838 and 839 of the Brazilian Civil Code, Article 595 of the Brazilian Civil Procedure Code.

Section 11.5 Subrogation. Upon making a payment under this Article XI, each Guarantor shall be subrogated to the rights of the payee against the Borrowers with respect to such obligation; provided that no Guarantor shall enforce any payment by way of subrogation, indemnity or otherwise, or exercise any other right, against the Borrowers (or otherwise benefit from any payment or other transfer arising from any such right) so long as any payment obligations of the Borrowers remain unpaid and/or unsatisfied under the Credit Documents.

Section 11.6 Stay of Acceleration. If acceleration of the time for payment of any amounts payable under the Credit Documents is stayed due to any event described in Section 10.5, then all such amounts otherwise subject to acceleration under this Agreement shall nonetheless be payable by the Guarantors hereunder immediately upon demand by the Administrative Agent.

ARTICLE XII

THE AGENTS

Section 12.1 Appointment, Powers and Immunities. (a) Each Bank hereby appoints and authorizes each of the Agents to act as its agent hereunder and (as applicable) under the other Credit Documents to which such Agent is a party with such powers as are specifically delegated to such Agent by the terms of this Agreement and (as applicable) the other Credit Documents to which such Agent is a party, together with such other powers as are reasonably incidental thereto. Each Agent (which term as used in this sentence and in Section 12.5 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 to which such Agent is a party 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 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 to which such Agent is a party, 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.

Each 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. Each 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 either Agent acts or refrains from acting, it may require an officer’s certificate from any Obligor and/or an opinion of counsel satisfactory to such Agent with respect to the proposed action or inaction at the Banks’ expense. Neither Agent shall 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 to which such Agent is a party, either 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 to which such Agent is a party, 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 such Agent, be deemed to be conclusively proved and established by an officers’ certificate delivered to such Agent, and such certificate, in the absence of gross negligence or bad faith on the part of such Agent, shall be full warrant to such 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 either Agent may be merged or consolidated or (ii) that may result from any merger, conversion or consolidation to which either Agent shall be a party shall (if such Agent is not the surviving entity) be the successor of such Agent without the execution or filing of any instrument or any further act on the part of any of the parties hereto.

Section 12.2 Reliance by the Agents. Each 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 such Agent. As to any matters not expressly provided for in the Credit Documents, the Collateral Agent shall in all cases be fully protected in relying upon the Administrative Agent’s instruction and the Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, thereunder in accordance 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 12.3 Defaults. Neither Agent shall 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 either Agent receives such a notice, then it shall give prompt notice thereof to the Banks and the Borrowers (if such notice is received from a Bank). The Administrative Agent shall (subject to Section 12.7) 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 12.4 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 an 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 an 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 12.5 Indemnification. The Banks agree to indemnify each Agent (to the extent not reimbursed under Section 13.1, but without limiting the obligations of the Obligors under Section 13.1) 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 to which such Agent is a party or the transactions contemplated hereby (including the costs and expenses that the Obligors are obligated to pay under Section 13.1, 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 either Agent for any of the foregoing to the extent that it arises from the gross negligence or willful misconduct of such Agent as determined by a final, nonappealable judgment by a court of competent jurisdiction. In no event shall any Bank be liable to either Agent for any punitive or consequential damages in connection with any of the Credit Documents. The obligations of the Banks under this Section 12.5 shall survive the termination of this Agreement, the repayment of the Loans and/or the earlier resignation or removal of an Agent.

Section 12.6 Non-Reliance upon the Agents and other Banks. Each Bank agrees that it has, independently and without reliance upon either 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 either 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. Neither Agent shall 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 to which such Agent is a party, neither Agent shall 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 such Agent or any of its Affiliates.

Section 12.7 Failure to Act. Except for any action expressly required of an Agent under a Credit Document to which such Agent is a party, 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 12.5 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 any 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. Notwithstanding the foregoing, the Collateral Agent shall at all times follow the instructions of the Administrative Agent or the Borrowers, as the case may be, but in no event shall the Collateral Agent at any time be directed by the Banks to take action.

Section 12.8 Resignation or Removal of the Agents. Subject to the appointment and acceptance of a successor Agent as provided below, each Agent may resign at any time by giving notice thereof to the Banks and the Obligors, and each 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 or Collateral Agent. If no successor Administrative Agent or Collateral Agent shall have been so appointed and shall have accepted such appointment within 30 days after the existing Agent’s giving of notice of resignation or the Majority Banks’ election to remove such existing Agent, then such existing Agent may, on behalf of the Banks, appoint a successor 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 or Collateral Agent, as the case may be, hereunder by a successor, such successor shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the existing Agent, and such existing Agent shall be discharged from its duties and obligations hereunder. After any Agent’s resignation or removal hereunder, the provisions of this Article XII 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 Agent.

Section 12.9 Limitation on Duty of Collateral Agent in Respect of Collateral. (a) Beyond the exercise of reasonable care in the custody thereof or as otherwise required under Applicable Law, the Collateral Agent shall have no duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto and the Collateral Agent shall not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any security interest in the Collateral. The Collateral Agent shall be deemed to have exercised reasonable care in the custody of the Collateral in its

possession if the Collateral is accorded treatment substantially equal to that which it accords its own property and shall not be liable or responsible for any loss or diminution in the value of any of the Collateral, by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Collateral Agent in good faith.

(b) The Collateral Agent shall not be responsible for the existence, genuineness or value of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, whether impaired by operation of law or by reason of any of any action or omission to act on its part hereunder, except to the extent such action or omission constitutes gross negligence, bad faith or willful misconduct on the part of the Collateral Agent, for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral.

Section 12.10 Concerning the Collateral Agent and the Collateral. The Collateral Agent shall have no duty to act outside of the United States in respect of any Collateral located in any jurisdiction other than the United States (“Foreign Collateral”) but shall at the specific request of the Administrative Agent, appoint a Person or Persons to act on behalf of the Secured Parties with respect to such Foreign Collateral. Such qualified Person or Persons and the Collateral Agent shall, provided the same are reasonably acceptable to the Collateral Agent, enter into a collateral assignment pledge agreement, mortgage, enforcing document or other security agreement purporting to relate to the Lien or security interest in such item of Foreign Collateral pursuant to which such Person or Persons shall exercise the rights and remedies of the Collateral Agent and Secured Parties in the Collateral for their respective benefit.

Section 12.11 Appointment of Collateral Agent. (a) Notwithstanding any other provisions of this Agreement, at any time, for the purpose of meeting any legal requirement of any jurisdiction in which any Collateral may at the time be located and for purposes of enforcement, the Collateral Agent shall have the power and may execute and deliver all instruments to appoint one or more Persons to act as its agent of the Secured Parties of all or any part of the Collateral, and to vest in such Person or Persons, in such capacity and for the benefit or on behalf of the Secured Parties, such title to the Collateral, or any part thereof, and such powers, duties, obligations, rights and trusts as the Collateral Agent may consider necessary or desirable, provided that the appointment of such agent shall be subject to the approval of the Administrative Agent, which approval shall not be unreasonably withheld, and provided further, that any such agent shall agree to be liable to the Secured Parties to the extent the Collateral Agent is so liable pursuant to this Agreement.

(b) All rights and powers, conferred or imposed upon the Collateral Agent may be conferred or imposed upon and may be exercised or performed by an agent.

(c) Any notice, request or other writing given to the Collateral Agent shall be deemed to have been given to each of the agents as effectively as if given to each of them. Every instrument appointing any agents shall refer to this Agreement.

(d) Any agent may at any time appoint the Collateral Agent as its agent or attorney in fact with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name.

(e) The Collateral Agent shall not be responsible for any willful misconduct or negligence on the part of any agent appointed with due care and in good faith pursuant to this Section.

ARTICLE XIII

MISCELLANEOUS

Section 13.1 Expenses; Indemnity.

(a) Whether or not the transactions contemplated hereby are consummated, the Borrowers hereby agree 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 Borrowers further agree 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.

(b) The Obligors hereby agree, on a joint and several basis, to indemnify each Bank and its respective directors, officers, employees, representatives, attorneys and agents (each an “Indemnified Person”) from, and hold each of them harmless against, any and all losses, liabilities, obligations, penalties, actions, judgments, suits, costs, claims, damages, disbursements or reasonable and documented expenses incurred by any of them as a result of, or arising out of, or in any way related to, or by reason of any investigation, litigation, arbitration or other proceeding (whether or not the Indemnified Person is a party thereto) (including any threatened investigation, litigation, arbitration or other proceeding) relating to the Credit Documents and/or the use or proposed use by the Borrowers of the proceeds of the Loans or the consummation of any transactions contemplated herein or in any other Credit Document,

including the reasonable and documented fees and disbursements of counsel incurred in connection with any such investigation, litigation or other proceedings (but excluding any such losses, liabilities, claims, damages or expenses incurred by reason of the gross negligence or willful misconduct of the Person to be indemnified, as determined by a final, nonappealable judgment by a court of competent jurisdiction). To the extent that any undertaking in this 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 13.1 shall survive the termination of this Agreement.

Section 13.2 Notices. Except as otherwise expressly provided herein, all notices and other communications provided for hereunder shall be in writing (including facsimile communication) and mailed, facsimiled or delivered: if to any Obligor, the Agents or any Bank, at its address specified on Schedule II hereto or, as to any Obligor or the Agents, at such other address as shall be designated by such party in a written notice to the other parties hereto and, as to each Bank, at such other address as shall be designated by such Bank in a written notice to the Borrowers and the Administrative Agent. All such notices and communications shall, when mailed, facsimiled, or sent by overnight courier, be effective when received.

Section 13.3 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 J; 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 13.3(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 13.3(b) will be effective until recorded by the Administrative Agent on the Register pursuant to Section 13.3(c). Notwithstanding the foregoing, no assignment after the date hereof shall increase the withholding tax burden on the Borrowers based on the Applicable 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 Borrowers hereby designate the Administrative Agent to serve as the Borrowers’ agent, solely for purposes of this Section 13.3(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 13.3(c) and Section 13.3(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 Borrowers’ obligations in respect of the Loans. Each 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 13.3(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 any scheduled Payment Date 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), (ii) consent to the assignment or transfer by any Obligor of any of its rights and obligations under this Agreement, (iii) amend, modify or waive any provision in Article XI hereof or release any Guarantor from any of their respective obligations hereunder, or (iv) release all or any portion of the Collateral (as such term is defined in the Security 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 Borrowers 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 13.3, any Bank may (without notice or consent of the Administrative Agent, the Borrowers or any other Person and without payment of any fee) assign 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 13.4 No Waiver; Remedies Cumulative. No failure or delay on the part of the Administrative Agent, the Collateral 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 Borrowers and the Administrative Agent, the Collateral 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 Borrowers in any case shall entitle the Borrowers to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the Administrative Agent, the Collateral 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 13.5 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 13.6 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 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 under each of the Credit Documents 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.

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.

Section 13.10 Survival. All indemnities set forth herein including, without limitation, in Article IV, Sections 11.3, 12.5, 13.1, 13.3 and 13.11 shall survive the execution and delivery of this Agreement and the Notes and the making and repayment of the Loans and any assignments thereof.

Section 13.11 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 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 13.12 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 13.13 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 13.13 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, provided that such prospective transferee agrees to maintain the confidentiality contained in this Section 13.13 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 Borrowers and such prospective counterparty agrees to maintain the confidentiality contained in this Section 13.13 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.

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 Borrowers that pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies the Borrowers, which information includes the name and address of each Borrower and other reasonable information that will allow such Bank, the Administrative Agent or the Collateral Agent, as applicable, to identify the Borrowers in accordance with the Patriot Act.

(a) the Grantors will remain liable under the Sales Agreements, the Intercompany Export Agreement and other Property included in the Collateral to the extent set forth therein, and will perform all of their duties and obligations under such Sales Agreements, Intercompany Export Agreement and other Collateral to the same extent as if this Agreement had not been executed;

(a) any lack of validity, legality or enforceability of any Credit Document;

(b) the failure of any Secured Party (i) to assert any claim or demand or to enforce any right or remedy against any Grantor or any other Person under the provisions of any Credit Document or otherwise, or (ii) to exercise any right or remedy against any Grantor, or collateral securing, any obligations (including the Secured Obligations);

ARTICLE III
FURTHER ASSURANCES; REMEDIES

(a) Delivery and Other Perfection. They shall:

(i) promptly deliver and pledge to the Collateral Agent any and all Collateral evidenced by a writing, in each case endorsed and/or accompanied by such instruments of assignment and transfer in such form and substance as is necessary or otherwise as the Collateral Agent (acting upon instructions of the Administrative Agent) may reasonably request,

(ii) (A) promptly give, execute, deliver, file and/or record any financing statement, notice, instrument, agreement or other document that may be necessary or desirable (in the reasonable judgment of either Agent) to create, preserve, perfect, or validate the security interest granted pursuant hereto or to enable the Collateral Agent to exercise and enforce their rights hereunder with respect to such pledge and security interest and (B) upon the occurrence of an Activation Event, to file or record any such financing statement, notice, instrument, agreement or other document with respect to the Springing Lien Collateral that may be necessary or desirable, provided that if the Grantors do not promptly make such a filing or recording after an Activation Event, the Grantors hereby direct and authorize the Collateral Agent to do so without further notice to or consent of the Grantors,

(iii) keep full and accurate books and records relating to the Collateral, and stamp or otherwise mark such books and records in such manner as either Agent may reasonably request in order to reflect the security interests granted by this Agreement, and

(iv) permit representatives of the Collateral Agent, upon reasonable notice and, with respect to the Springing Lien Collateral, upon the occurrence of an Activation Event, at any time during normal business hours to inspect and make copies of and abstracts from its books and records pertaining to the Collateral, and permit representatives of the Collateral Agent to be present at each Grantor’s place of business to receive copies of all communications and remittances relating to the Collateral, and forward copies of any material notices or communications received by the Grantors with respect to the Collateral, all in such manner as any Secured Party may reasonably request.

(b) No Other Liens. Other than the security interest granted herein, the Grantors shall not incur, enter into or suffer to exist any Lien upon the Account Collateral or the Springing Lien Collateral at any time.

(c) Preservation of Rights. The Collateral Agent shall not be required to take steps necessary to preserve any rights against prior parties to any of the Collateral.

C-7

(d) Event of Defaults. While any Event of Default exists and the Collateral Agent is notified in writing of the existence thereof by the Administrative Agent:

(i) the Collateral Agent (on behalf of the Secured Parties) shall have all of the rights and remedies with respect to the Collateral of a secured party under the UCC (whether or not such code is in effect in the jurisdiction where the rights and remedies are asserted) and all additional rights and remedies to which a secured party is entitled under the Applicable Laws in effect in any jurisdiction where any rights and remedies hereunder may be asserted, including the right, to the maximum extent permitted by Applicable Law, to exercise all powers of ownership pertaining to the Collateral as if the Collateral Agent were the sole and absolute owner thereof (and the Grantors agree to take all such action as may be necessary or reasonably requested by the Collateral Agent to give effect to such right);

(ii) the Collateral Agent may, and at the request of the Majority Banks, shall in its name or in the name of the Grantors or otherwise, demand, sue for, collect or receive any money or other Property at any time payable or receivable on account of or in exchange for any of the Collateral, but shall be under no obligation to do so;

(iii) the Collateral Agent may, and at the request of the Majority Banks, shall, to the extent permitted by Applicable Law, and upon at least ten days’ prior written notice to the Grantors of the time and place, cause the sale of all or any part of the Collateral through agents or otherwise, at such place(s) as the Majority Banks deem best, and for cash or for credit or for future delivery (without thereby assuming any credit risk), at public or private sale, without demand of performance or notice of intention to effect any such disposition or of the time or place thereof (except such notice as is required above or by Applicable Law and cannot be waived), and any Person (including the Administrative Agent, the Collateral Agent and any other Secured Party) may be the purchaser of any or all of such Collateral at any public sale (or, to the extent permitted by Applicable Law, at any private sale) and thereafter hold the same absolutely, free from any claim or right of whatsoever kind, including any right or equity of redemption (statutory or otherwise), of the Grantors, any such demand, notice and right or equity being hereby expressly waived and released by the Grantors. The Collateral Agent may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for the sale, and such sale may be made at any time or place to which the sale may be so adjourned; and

(iv) any action taken by the Collateral Agent hereunder shall be taken in good faith and in a commercially reasonable manner.

The Grantors acknowledge that, by reason of prohibitions contained in the United States Securities Act of 1933, as amended, and applicable state securities laws, there may be a need with respect to any sale of all or any part of the Collateral constituting securities, to limit purchasers to those who agree, among other things, to acquire the Collateral for their own account, for investment and not with a view to the distribution or resale thereof. If any such sale

C-8

of Collateral is made in accordance with this Agreement, then the parties hereto acknowledge (and each Secured Party shall be deemed to have acknowledged) that any price obtained in a public or private sale of such Collateral shall be conclusive and binding upon each of the parties thereto and hereto (and each of the Secured Parties), to the extent permitted by Applicable Law.

(e) Deficiency. If the proceeds of collection or other realization of or upon the Collateral are insufficient to cover the costs and expenses of such realization and the payment in full of the Secured Obligations, then the Grantors shall remain liable for any deficiency.

(f) Books and Records; UCC Matters. Without at least 30 days’ prior written notice to the Collateral Agent: each Grantor (i) shall not maintain any of its books and records with respect to the Collateral at any office or maintain its principal place of business at any place other than in its jurisdiction of incorporation or formation, (ii) shall not change its jurisdiction of organization and (iii) shall not change its name, or the name under which it does business, from the name shown on the signature pages hereto.

(g) Private Sale. Each Grantor acknowledges (and each Secured Party will be deemed to have acknowledged) that any private sale of any of the Collateral may be at prices and on terms less favorable than those obtainable through a public sale and agrees (or will be deemed to have agreed) that any such private sale pursuant to Section 3.1(d)(iii) made in accordance with Applicable Law shall be deemed to have been made in a commercially reasonable manner and that the Collateral Agent or the Secured Parties shall have no obligation to engage in public sales unless required by any Applicable Law. Neither the Collateral Agent nor any of the other Secured Parties shall incur any liability as a result of the sale of the Collateral, or any part thereof, at any private sale conducted in a commercially reasonable manner and made in accordance with Applicable Law. Each Grantor hereby waives (and each Secured Party will be deemed to have waived) any claims against the Collateral Agent, the Administrative Agent or any other Secured Party arising by reason of the fact that the price at which the Collateral may have been sold at such private sale made in accordance with Applicable Law was less than the price that might have been obtained at a public sale or was less than the aggregate amount of the Secured Obligations, even if the Collateral Agent accepts the first offer received and does not offer such sold Collateral to more than one offeree.

(h) Clean Sale. Upon any sale of Collateral under this Section made in accordance with Applicable Law, the Collateral Agent shall have the right to deliver, assign and transfer to the purchaser thereof the Collateral so sold. Each purchaser at any such sale shall hold the Collateral so sold to it absolutely and free from any Lien, claim or right of any kind, and the Grantors, to the extent permitted by Applicable Law, hereby specifically waives all rights of redemption, stay or appraisal that it has or may have under any Applicable Law with respect thereto. Each Grantor shall execute and deliver such documents and take such other actions as the Collateral Agent (acting upon instructions of the Majority Banks) deems necessary or advisable in order that any such sale may be made in compliance with Applicable Law.

(i) Application of Proceeds. Notwithstanding anything herein to the contrary, the proceeds of any collection, sale or other realization of all or any part of the Collateral pursuant to this Section, and any other cash at the time held by the Collateral Agent under this Article, shall be applied by the Collateral Agent as follows: (i) first, to payment in full of all

C-9

costs and expenses (including indemnities owed to the Collateral Agent) relating to such collection, sale or other realization (including attorney fees and expenses and the compensation of the Collateral Agent for services rendered in connection therewith or in connection with any proceeding to sell if a sale is not completed), (ii) second, to payment in full of all charges, expenses and advances incurred or made by the Collateral Agent in order to protect the security interest granted hereunder and/or the security afforded thereby, (iii) third, to payment in full of all fees and expenses then due and payable to the Banks, the Administrative Agent and the Collateral Agent, (iv) fourth, to payments to the Secured Parties to satisfy the Secured Obligations in the manner described herein as if such amounts were collections from Export Receivables, and (v) fifth, any remaining amounts shall be paid to, or at the written direction of, the Grantors.

(j) Attorney-in-Fact. Upon the occurrence of an Activation Event, the Collateral Agent is hereby appointed the attorney-in-fact of each of the Grantors for the purpose of carrying out the provisions of this Article III and taking any action and executing and delivering any documents that the Collateral Agent may deem necessary or advisable to accomplish the purposes hereof provided that any action taken by the Collateral Agent is taken or made in good faith and in a commercially reasonable manner, which appointment as attorney-in-fact is irrevocable and coupled with an interest; it being understood that the grant of an attorney-in-fact is subject at all times to Section 2.3(c) hereof. Without limiting the generality of the foregoing, so long as the Collateral Agent shall be entitled under this Article III to make collections in respect of the Collateral, the Collateral Agent shall have the right and power to receive, endorse and collect all checks and other instruments made payable to the order of the Grantors representing any payment or other distribution in respect of the Collateral (including the Export Receivables) or any part thereof and to give full discharge for the same.

(k) Termination. When all of the Secured Obligations shall have been finally paid in full (other than any indemnification obligations not yet incurred), this Agreement shall terminate and, upon written notice from the Administrative Agent to the Collateral Agent, the Collateral Agent shall (at the written request and direction of the Grantors): (i) cause to be assigned, transferred and delivered, against receipt but without any recourse, warranty or representation whatsoever, any remaining Collateral (including funds received in respect thereof) to or on the order of the Grantors; (ii) deliver to the Grantors any Collateral or other Property of the Grantors in the possession of the Collateral Agent; and (iii) deliver lien releases and Uniform Commercial Code termination statements and notices of termination of the Account Control Agreement.

(l) Further Assurances. Each Grantor shall, at its own cost, promptly take all actions necessary or reasonably requested by the Collateral Agent to maintain the Lien created hereby in full force and effect and enforceable in accordance with its terms, including: (i) making necessary filings and recordations, (ii) making payments of documented fees and other charges, (iii) issuing and, if necessary, filing or recording supplemental documentation, including continuation statements, (iv) discharging all claims or other Liens adversely affecting the rights of the Collateral Agent or any other Secured Party in any Collateral, (v) publishing or otherwise delivering notice to third parties, (vi) depositing title documents, (vii) taking such other steps as are necessary or as otherwise the Collateral Agent may reasonably request to perfect and

C-10

maintain the perfection of the security interest in the Collateral and (viii) taking all other actions either necessary or reasonably requested by the Collateral Agent to ensure that all after-acquired property of the Grantors intended to be covered by such Liens is subject to a valid and enforceable first priority perfected Lien in favor of the Collateral Agent (on behalf of the Secured Parties).

(m) Activation Event. Upon the occurrence of an Activation Event and at all times thereafter, the Off-taker shall immediately (i) notify each Designated Eligible Buyer of the assignment of its rights under such Designated Eligible Buyer’s Sales Agreement(s) and to all Export Receivables generated in connection therewith, and irrevocably instruct each Designated Eligible Buyer to make all payments in respect of such Export Receivables to the Collection Account by sending each Designated Eligible Buyer a Designated Eligible Buyer Notice, and shall provide copies of such Designated Eligible Buyer Notices to the Collateral Agent, and (ii) cause to be collected from the Designated Eligible Buyers as and when due (including amounts that are delinquent), any and all amounts owing under or on account of the Export Receivables. It is expressly agreed that, if the Off-taker fails to take the actions specified in this Section 3.1(m), then the Collateral Agent may send such Designated Eligible Buyer Notices directly to Designated Eligible Buyers and take any other action in accordance with the terms hereof.

(n) As to Commercial Tort Claims. Each Grantor hereby covenants and agrees that, until the final payment in full of the Secured Obligations and termination of this Agreement, with respect to any Commercial Tort Claim hereafter arising which are included in the Collateral, it shall (i) notify the Collateral Agent thereof and (ii) if requested by the Collateral Agent after the occurrence of an Activation Event (acting upon instructions of the Administrative Agent), deliver to the Collateral Agent a supplement to this Agreement in form reasonably acceptable to the Collateral Agent (acting upon instructions of the Administrative Agent) granting the Collateral Agent a security interest in such Commercial Tort Claim.

ARTICLE IV
REPRESENTATIONS AND WARRANTIES

Section 4.1 Representations and Warranties. As of the date hereof and as of the date of the occurrence of the Activation Event, each of the Grantors represents and warrants to the Secured Parties that:

(a) Power and Authority. It has the full power to pledge its right, if any, to the Account Collateral and the Springing Lien Collateral without any third-party rights being violated by such pledge.

(b) Ownership and Liens. It is (or shall be) the sole beneficial owner of the Collateral in which it grants a security interest pursuant to Article II and no Lien exists or will exist upon the Account Collateral or the Springing Lien Collateral at any time, other than the pledge and security interest created or provided for herein, which pledge and security interest: (i) constitute a valid and enforceable perfected first priority pledge and security interest in and to all of the Account Collateral, and (ii) will constitute, upon the occurrence of an Activation Event, a valid and enforceable perfected first priority pledge and security interest in and to all of the

C-11

Springing Lien Collateral, perfected by the filing of a UCC financing statement in the District of Columbia in favor of the Collateral Agent and the filing of a sworn translation of this Agreement with the competent Registry of Deeds and Documents in Brazil (in each case, with respect to the Springing Lien Collateral).

(i) Other than, in respect of the Springing Lien Collateral, the filings described in subsection (b) above, which will be done upon the occurrence of an Activation Event, all notices, filings, registrations and recordings necessary or appropriate under United States, Cayman Islands and Brazilian Applicable Law to create, preserve, protect and perfect the security interest in the Account Collateral and the Springing Lien Collateral granted by the Grantors to the Collateral Agent (as agent for the Secured Parties) have been accomplished.

(ii) This Agreement is effective to create the security interest in the Account Collateral and, upon the occurrence of an Activation Event, in the Springing Lien Collateral intended to be created hereby and granted to the Collateral Agent (as agent for the Secured Parties).

(d) Third Party Approvals. Except for the filing of UCC financing statements in the District of Columbia and the filing of a sworn translation of this Agreement with the competent Registry of Deeds and Documents in Brazil with respect to the Liens on the Springing Lien Collateral, which will be done upon the occurrence of an Activation Event, all governmental approvals and other actions by, and all notices to and filings and registrations with, any Governmental Authority, and all third-party approvals, required for the due execution, delivery and performance by the Grantors of this Agreement and for the legality, validity or enforceability hereof have been obtained and are in full force and effect and true copies thereof have been provided to the Collateral Agent.

(e) Legal Effect. This Agreement has been duly executed and delivered by each Grantor and is the legal, valid and binding obligation of such Grantor, enforceable against it in accordance with its terms, in each case except as may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors’ rights generally and as may be limited by equitable principles of general applicability.

(f) Other Financing Statements. Other than in connection with the security interest granted herein, there is no notice of assignment, financing statement (or similar statement or instrument of registration under the Applicable Law of any jurisdiction) executed or registered by each Grantor or, to its knowledge, by any other Person with respect to any interest of any kind in any of the Account Collateral or any of the Springing Lien Collateral.

(g) Commercial Activity; Absence of Immunity. Each Grantor is subject to civil and commercial law with respect to its obligations hereunder and under the Sales Agreements and the Intercompany Export Agreement, and the making and performance by it of such documents to which it is a party constitute private and commercial acts rather than public or governmental acts. Neither any Grantor nor any of its Properties is entitled to immunity on the

C-12

grounds of sovereignty or otherwise from the jurisdiction of any court or from any action, suit, set-off or proceeding, or service of process in connection therewith, arising under any such documents.

ARTICLE V
THE COLLATERAL AGENT

Section 5.1 Appointment, Powers and Immunities. (a) Each Secured Party has appointed and authorized (or will be deemed to have appointed and authorized) the Collateral Agent to act as its agent hereunder and under the Account Control Agreement with respect to the Collection Account with such powers as are specifically delegated to it by the terms hereof, together with such other powers as are reasonably incidental thereto. In addition to the rights, benefits, protections and immunities provided to the Collateral Agent in the Term Loan Agreement, the Collateral Agent (which term as used in this sentence, in Section 5.5 and in the first sentence of Section 5.6 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 herein, in the Account Control Agreement and in the other agreements to which it is a party and shall not by reason of any such agreement be a trustee or fiduciary for any Secured Party,

(ii) shall not be responsible to the Secured Parties for any recitals, statements, representations or warranties contained herein, or in any document referred to or provided for herein, or received by any of them hereunder, or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of the Collateral or any document referred to or provided for herein or for any failure by any Grantor or any other Person to perform any of its obligations hereunder or thereunder,

(iii) shall not be required to initiate or conduct any litigation or collection proceedings, and

(b) The Collateral Agent may employ agents, attorneys-in-fact, accountants, appraisers or other experts or advisers and shall not be responsible for the negligence or misconduct of or for the supervision of any such Persons that are selected by it in good faith.

(c) Before the Collateral Agent acts or refrains from acting, it may require a certificate from any Person and/or an opinion of counsel satisfactory to the Collateral Agent with respect to the proposed action or inaction. The Collateral 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 Collateral, the Collateral Agent shall deem it necessary or desirable that a matter be provided or established before taking or suffering or omitting to take any act with respect to the Collateral, 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

C-13

Collateral Agent, be deemed to be conclusively proved and established by an officers’ certificate delivered to the Collateral Agent, and such certificate, in the absence of gross negligence or bad faith on the part of the Collateral Agent, may be relied upon by the Collateral Agent for any action taken, suffered or omitted to be taken by it in reliance thereon.

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

(e) The Collateral Agent shall be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property.

Section 5.2 Reliance by the Collateral Agent. The Collateral 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 Collateral Agent. As to any matters not expressly provided for in any document to which it is a party, the Collateral Agent shall in all cases be fully protected in acting, or in refraining from acting, thereunder in accordance with written instructions given by the Majority Banks (or Banks, as the context requires), and such instructions of the Administrative Agent and any action taken or failure to act pursuant thereto shall be binding upon all of the Secured Parties.

Section 5.3 Event of Defaults. The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of an Activation Event or an Event of Default unless it has received written notice from the Administrative Agent or any of the Borrowers or Grantors, specifying such Activation Event or Event of Default. The Collateral Agent shall take such action with respect to any Event of Default as the Majority Banks shall direct.

Section 5.4 Rights as a Creditor. JPMorgan Chase Bank, N.A. (and any successor acting as the Collateral Agent) shall have the same rights and powers as any other Secured Party and may exercise the same as though it were not acting as the Administrative Agent or the Collateral Agent. JPMorgan Chase Bank, N.A. (and any successor acting as the Collateral Agent) and its Affiliates may (without having to account therefore to any other Secured Party) accept deposits from, lend money to, make investments in and generally engage in any kind of banking, trust or other business with the Borrowers, the Grantors or any other Guarantor, any customer thereof (including any Designated Eligible Buyer), any Secured Party and any Affiliate of any thereof as if it were not acting as the Collateral 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 Secured Parties.

Section 5.5 Indemnification. The Banks agree to indemnify the Collateral Agent in the manner described in Section 12.5 of the Term Loan Agreement.

C-14

Section 5.6 Non-Reliance upon the Collateral Agent. Each Secured Party will be deemed to have agreed that it has, independently and without reliance upon the Collateral Agent, and based upon such documents and information as it has deemed appropriate, made its own credit analysis of the Borrowers, the Grantors and the other Guarantors and their Affiliates and has made a decision to become a creditor of the Secured Obligations and that it will, independently and without reliance upon the Collateral Agent, 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 with respect thereto. The Collateral Agent shall not be required to keep itself informed as to the performance or observance by the Grantors or any other Person of this Agreement or any other document referred to or provided for herein or to inspect the Properties or books of the Grantors or any other Person. Except for notices, reports and other documents and information expressly required to be furnished by it under the documents to which it is a party, the Collateral Agent shall not have any duty or responsibility to provide any Secured Party with any credit or other information concerning the affairs, financial condition or business of the Borrowers, the Grantors or the other Guarantors or any other Person that may come into the possession of the Collateral Agent or any of its Affiliates.

Section 5.7 Failure to Act. Except for any action expressly required of the Collateral Agent under a document to which it is a party, it shall in all cases be fully justified in failing or refusing to act unless it shall receive further assurances to its satisfaction from the applicable Secured Parties of their indemnification obligations under Section 5.5 against any and all liability and expense that may be incurred by the Collateral Agent by reason of taking or continuing to take any such action. No provision of any document shall require the Collateral Agent to take any action that it reasonably believes to be contrary to Applicable Law or would subject it to personal liability, 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 hereunder. The Collateral Agent shall not be obligated to exercise discretion hereunder but should act or refrain from acting upon the written direction of the Majority Banks.

Section 5.8 Reporting Requirement. After the occurrence of an Activation Event, no later than twenty (20) days after the last day of each Interest Period ending after the date of the occurrence of such Activation Event, the Collateral Agent shall deliver a report to the Administrative Agent and the Grantors setting forth the aggregate amount of the collections in the Collection Account that have been deposited into the Collection Account during such Interest Period.

ARTICLE VI
MISCELLANEOUS

Section 6.1 Waiver. No failure on the part of the Collateral Agent or any other Secured Party to exercise and no delay in exercising, and no course of dealing with respect to, any right, power or privilege under this Agreement or the Account Control Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege under this Agreement preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The remedies provided in this Agreement are cumulative and not exclusive of any other remedies provided by Applicable Law.

The Intermediary has established the Collection Account (account number 304952265) maintained on the Intermediary’s books and records at the principal office of the Intermediary in New York, New York at the request of the Off-taker and Collateral Agent. The Intermediary will act as “securities intermediary” (within the meaning of Section 8-102 of the UCC) in regards to the Collection Account which the Off-taker and Collateral Agent intend to be a “securities account” (within the meaning of Section 8-501 of the UCC) to which “financial assets” (within the meaning of Section 8-102 of the UCC) are or may be credited and the Intermediary agrees to treat the Off-taker as entitled to exercise the rights that comprise the “financial assets” credited thereto.

All property delivered to the Intermediary pursuant to the Credit Documents for credit thereto shall be promptly credited (by book entry of otherwise) to the Collection Account.

SECTION 3. Financial Assets Election. Each of the parties hereto agrees that each item of property (whether any security, instrument, obligation, share, participation, interest or other property whatsoever but excluding cash) at any time in the Collection Account shall be treated as a “financial asset” (within the meaning of Section 8-102 of the UCC).

SECTION 4. Duties and Liabilities of the Intermediary Generally.

In no event shall the Intermediary be liable for indirect, special or consequential damages of any kind whatsoever (including lost profits and lost business opportunity) even if it is advised of the possibility of such damages and regardless of the form of action in which any such damages may be claimed. Without limiting the foregoing, and notwithstanding any provision to the contrary elsewhere, the Intermediary and its officers, employees and agents:

(a) shall have no duty to preserve, exercise or enforce rights in the financial assets (against prior parties or otherwise);

(b) may in any instance where the Intermediary determines that it lacks or is uncertain as to its authority to take or refrain from taking certain action, or as to the requirements of this Agreement under any circumstance before it, delay or refrain from taking action unless and until it has received instructions from the Collateral Agent or advice from legal counsel (or other appropriate advisor), as the case may be

(c) so long as it and they shall have acted (or refrained from acting) in good faith, shall not be liable for any error of judgment in any action taken, suffered or omitted by, or for

D-2

any act done or step taken, suffered or omitted by, or for any mistake of fact or law, unless such action constitutes gross negligence or willful misconduct on its (or their) part;

(d) may consult with legal counsel selected by it (or other experts for the Off-taker or Collateral Agent), and shall not be liable for any action taken or not taken by it or them in good faith in accordance with the advice of such experts;

(e) will not be responsible to the Collateral Agent for any statement, warranty or representation made by any party other than the Intermediary in connection with this Agreement except as set forth in Section 7 below;

(f) will have no duty to ascertain or inquire as to the performance or observance by the Off-taker of any of the terms, conditions or covenants of the Security Agreement;

(g) will not be responsible to Off-taker or Collateral Agent for the due execution, legality, validity, enforceability, genuineness, effectiveness or sufficiency of this Agreement, (provided, however, that the Intermediary warrants below that the Intermediary has legal capacity to enter into this Agreement);

(h) will not incur any liability by acting or not acting in reliance upon any notice, consent, certificate, statement or other instrument or writing believed by it or them to be genuine and signed or sent by the proper party or parties;

(i) will not incur liability for any notice, consent, certificate, statement, wire instruction, telecopy, or other writing which is delayed, canceled or changed without the actual knowledge of the Intermediary;

(j) shall not be deemed to have or be charged with notice or knowledge of any fact or matter unless a written notice thereof has been received by the Intermediary at the address and to the person designated in (or as subsequently designated pursuant to) this Agreement;

(k) shall not be obligated or required by any provision of this Agreement to expend or risk the Intermediary’s own funds, or to take any action (including but not limited to the institution or defense of legal proceedings) which in its or their judgment may cause it or them to incur or suffer any expense or liability; provided, however, if the Intermediary elects to take any such action it shall be entitled to security or indemnity for the payment of the costs, expenses (including but not limited to attorneys’ fees) and liabilities which may be incurred therein or thereby, satisfactory to the Intermediary;

The Off-taker agrees that the Intermediary shall, comply with instructions originated by the Collateral Agent directing disposition of funds in the Collection Account, without further consent by the Off-taker or any other Person. The Intermediary shall have no obligation to act, and shall be fully protected in refraining from acting, in respect of the financial assets or funds, as applicable, credited to the Collection Account, in the absence of any such entitlement order or instruction.

The Intermediary shall comply with entitlement orders and other directions concerning financial assets or funds, as applicable, credited to the Collection Account at the direction of the Off-taker, until such time as the Collateral Agent delivers a written notice to the Intermediary in the form annexed hereto as Exhibit 1, that the Collateral Agent is thereby exercising exclusive control over the account (such notice may be referred to herein as the “Notice of Exclusive Control”). After the Intermediary receives the Notice of Exclusive Control, it will promptly cease complying with entitlement orders or other directions concerning the account originated by the Off-taker or its representatives.

SECTION 6. Subordination of Lien; Waiver of Set-Off. If the Intermediary has or subsequently obtains by agreement, operation of law or otherwise a security interest in the Collection Account or any security entitlement in respect of financial assets carried therein or funds deposited therein, as applicable, then the Intermediary hereby agrees that such security interest shall be subordinate to the security interest of the Collateral Agent (on behalf of the Secured Parties) under the Security Agreement, and agrees that the financial assets standing to the credit thereof shall not be subject to deduction, set-off, banker’s lien or any other right in favor of any Person other than the Collateral Agent (except for the face amount of any checks that have been credited thereto and funds on deposit therein but are subsequently returned unpaid because of uncollected or insufficient funds); provided that the Intermediary may set off from the Collection Account all amounts due to it in respect of its customary fees and expenses for the routine maintenance and operation of such account. Notwithstanding anything herein to the contrary, the Intermediary shall have a lien senior to that of the Collateral Agent for any and all amounts required for the payment of the purchase price of a financial asset, which purchase has been placed but not yet cleared or settled.

SECTION 7. Representations, Warranties and Covenants of the Intermediary. The Intermediary agrees with and, as of the date hereof, represents and warrants to the Collateral Agent as follows:

D-4

(c) The Intermediary has not entered into, and until the termination of this Agreement shall not enter into: (i) any agreement with any other Person relating to the Collection Account and/or any property (including uninvested funds) credited thereto or carried therein pursuant to which it agrees to comply with entitlement orders of, or instructions directing distribution of uninvested funds from, such Person or (ii) any other agreement with the Off-taker or any other Person purporting to limit or condition the obligation of the Intermediary to comply with entitlement orders and instructions directing distribution of uninvested funds originated by the Collateral Agent as set forth in Section 5. The Intermediary shall not comply with any entitlement orders or instructions directing distribution of uninvested funds originated by any Person with respect to the property (including uninvested funds) carried in or credited to the Collection Account other than the Collateral Agent or the Off-taker in accordance with the terms of the Security Agreement.

SECTION 8. Notice of Adverse Claims.

If any Person other than the Collateral Agent asserts any Lien, claim or interest (including any writ, garnishment, judgment, warrant of attachment, execution or similar process) against the Collection Account or in respect of any financial asset credited thereto or uninvested funds on deposit therein, then the Intermediary shall promptly notify the Collateral Agent and the Off-taker thereof.

SECTION 10. Termination; Resignation. The rights and powers granted herein to the Collateral Agent have been granted in order to perfect its security interests in the Collection Account, are powers coupled with an interest and are not intended to be affected by the bankruptcy (or similar event) of the Off-taker or the lapse of time. The obligations of the Intermediary hereunder shall continue in effect until the security interest of the Collateral Agent in the Collection Account has been terminated pursuant to the Security Agreement and the

D-5

Collateral Agent has notified the Intermediary of such termination in writing.

SECTION 11. Waiver. No failure on the part of the Collateral Agent or any other Secured Party to exercise and no delay in exercising, and no course of dealing with respect to, any right, power or privilege under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege under this Agreement preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The remedies provided in this Agreement are cumulative and not exclusive of any other remedies provided by Applicable Law.

Any other tax returns required to be filed will be prepared and filed by Off-taker with the IRS and any other taxing authority as required by law. The Parties acknowledge and agree that the Intermediary shall have no responsibility for the preparation and/or filing of any income, franchise or any other tax return with respect to the Collection Account or any income earned by the financial assets and funds. The Parties further acknowledge and agree that any taxes payable from the income earned on the investment of any sums held in the Collection Account shall be paid by Off-taker. Intermediary shall withhold any taxes it deems appropriate, including but not limited to required withholding in the absence of proper tax documentation, and shall remit such taxes to the appropriate authorities.

Each Exporter 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 designation of a process agent pursuant to this paragraph in full force and effect and to cause such process agent to act as such.
