Notwithstanding the foregoing, in the event that Rule 3-10 or Rule 3-16 of Regulation S-X under the Securities Act of 1933, as amended (“Rule 3-10” or “Rule 3-16”, as applicable) requires or is amended, modified or interpreted by the Securities Exchange Commission (“SEC”) to require (or is replaced with another rule or regulation, or any other law, rule or regulation is adopted, which would require) the filing with the SEC (or any other Governmental Authority) of separate financial statements of any Subsidiary of the Borrower due to the fact that such Subsidiary’s Equity Interests secure Obligations, then the Equity Interests of such Subsidiary will automatically be deemed not to be part of the Collateral securing any of the Obligations (whether or not affected thereby) but only to the extent necessary to not be subject to such requirement and only for so long as required to not be subject to such requirement. In such event, this Agreement may be amended or modified, without the consent of any Secured Party, to the extent necessary to release the Lien in favor of the Agent on the Equity Interests that are so deemed to no longer constitute part of the Collateral for the Obligations. In the event that Rule 3-10 or Rule 3-16 is amended, modified or interpreted by the SEC to permit (or is replaced with another rule or regulation, or any other law, rule or regulation is adopted, which would permit) such Subsidiary’s Equity Interests to secure the Obligations in excess of the amount then pledged without the filing with the SEC (or any other Governmental Authority) of separate financial statements of such Subsidiary, then the Equity Interests of such Subsidiary will automatically be deemed to be a part of the Collateral for the Obligations (but only to the extent that will not result in such Subsidiary being subject to any such financial statement requirement). In such event, this Agreement may be amended or modified, without the consent of any Secured Party, to the extent necessary to subject to the Lien in favor of the Agent such additional Equity Interests, on the terms contemplated herein.

The Agent shall be authorized in connection with any sale of a security (if it deems it advisable to do so) pursuant to the foregoing to restrict the prospective bidders or purchasers to persons who represent and agree that they are purchasing such security for their own account, for investment, and not with a view to the distribution or sale thereof . Upon consummation of any such sale of Collateral pursuant to this Section 4.01, the Agent shall have the right to assign and transfer to the purchaser or purchasers thereof the Collateral so sold. The property sold shall be done so absolutely, free from any claim or right on the part of the Pledgor, and the Pledgor hereby waives and releases (to the extent permitted by law) all rights of redemption, stay, valuation and appraisal that the Pledgor now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted.

The Agent shall give the Pledgor 10 days’ written notice (which each Pledgor agrees is reasonable notice within the meaning of Section 9-611 of the New York UCC or its equivalent in other jurisdictions) of the Agent’s intention to make any sale of Collateral. At any such sale, the Collateral, or the portion thereof, to be sold may be sold in one lot as an entirety or in separate parcels, as the Agent may (in its sole and absolute discretion) determine. The Agent may, without notice or publication, adjourn any private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale, and such sale may, without further notice, be made at the time and place to which the same was so adjourned. At any public (or, to the extent permitted by law, private) sale made pursuant to this Section 4.01, any Secured Party may bid for or purchase for cash, free (to the extent permitted by law) from any right of redemption, stay, valuation or appraisal on the partof the Pledgor (all such rights being also hereby waived and released to the extent permitted by law), the Collateral or any part thereof offered for sale and such Secured Party may, upon compliance with the terms of sale, possess, retain and dispose of such property without further accountability to the Pledgor therefor. For purposes hereof, a written agreement to purchase the Collateral or any portion thereof shall be treated as a sale thereof ; the Agent shall be free to carry out such sale pursuant to such agreement and the Pledgor shall not be entitled to the return of the Collateral or any portion thereof subject thereto, notwithstanding the fact that after the Agent shall have entered into such an agreement all Events of Default shall have been remedied and the Obligations paid in full. As an alternative to exercising the power of sale herein conferred upon it, the Agent may proceed by a suit or suits at law or in equity to foreclose this Agreement and to sell the Collateral or any portion thereof pursuant to a judgment or decree of a court or courts having competent jurisdiction or pursuant to a proceeding by a court-appointed receiver. To the extent provided in this Section 4.01, any sale that complies with such provisions shall be deemed to conform to the commercially reasonable standards as provided by the Brazilian Civil Code.

SECTION 4.02.                         Application of Proceeds. Subject to the terms of the Pari Passu Intercreditor Agreement, upon the occurrence and during the continuance of an Event of Default, the Agent shall promptly apply the proceeds, moneys or balances of any collection or

12

sale of Collateral, as well as any Collateral consisting of cash in accordance with Section 2.01 of the Pari Passu Intercreditor Agreement:

The Agent shall have absolute discretion as to the time of application of any such proceeds, moneys or balances in accordance with this Agreement. Upon the request of the Agent prior to any distribution under this Section 4.02, each Authorized Representative shall provide to the Agent certificates, in form and substance reasonably satisfactory to the Agent, setting forth the respective amounts referred to in this Section 4.02, that each applicable Secured Party or their Authorized Representative believes it is entitled to receive, and the Agent shall be fully entitled to rely on such certificates. Upon any sale of Collateral by the Agent (including pursuant to a power of sale granted by statute or under a judicial proceeding), the receipt of the purchase money by the Agent or of the officer making the sale shall be a sufficient discharge to the purchaser or purchasers of the Collateral so sold and such purchaser or purchasers shall not be obligated to see to the application of any part of the purchase money paid over to the Agent or such officer or be answerable in any way for the misapplication thereof.
