(b)any modification or amendment of or supplement to the Indenture or any Note;

(c)any change in the corporate existence, structure or ownership of the Substituted Issuer, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting the Substituted Issuer or its assets or any resulting release or discharge of any obligation of the Substituted Issuer contained in the Indenture or any Note;

(d)the existence of any claim, set‑off or other rights which the Guarantor may have at any time against the Substituted Issuer, the Trustee or any other Person, whether in connection with the Indenture or any unrelated transactions, provided that nothing herein prevents the assertion of any such claim by separate suit or compulsory counterclaim;

(e)any invalidity or unenforceability relating to or against the Substituted Issuer for any reason of the Indenture or any Note, or any provision of applicable law or regulation purporting to prohibit the payment by the Substituted Issuer of the principal of or interest on any Note or any other amount payable by the Substituted Issuer under the Indenture; or

(f)any other act or omission to act or delay of any kind by the Substituted Issuer, the Trustee or any other Person or any other circumstance whatsoever which might, but for the provisions of this paragraph, constitute a legal or equitable discharge of or defense to the Guarantor’s obligations hereunder.

Section 3.03.Discharge; Reinstatement.  The Guarantor’s obligations hereunder will remain in full force and effect until the principal of, premium, if any, and interest on the Notes and all other amounts payable by the Substituted Issuer under the Indenture have been paid in full.  If at any time any payment of the principal of, premium, if any, or interest on any Note or any other amount payable by the Substituted Issuer under the Indenture is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of the Substituted Issuer or otherwise, the Guarantor’s obligations hereunder with respect to such payment will be reinstated as though such payment had been due but not made at such time.

Section 3.06.Stay of Acceleration.  If acceleration of the time for payment of any amount payable by the Substituted Issuer under the Indenture or the Notes is stayed upon the insolvency, bankruptcy or reorganization of the Substituted Issuer, all such amounts otherwise subject to acceleration under the terms of the Indenture are nonetheless payable by the Guarantor hereunder forthwith on demand by the Trustee or the Holders.

Section 3.07.Execution and Delivery of Guarantee.  The execution by the Guarantor of this Third Supplemental Indenture evidences the Guarantee of the Guarantor, whether or not the person signing as an officer of the Guarantor still holds that office at the time of authentication of any Note.  The Guarantor hereby agrees that its Guarantee set forth in this Article shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes. The delivery of any Note by the Trustee after authentication constitutes due delivery of the Guarantee set forth in this Third Supplemental Indenture on behalf of the Guarantor.

In such event, and subject to Section 3.01 of the Indenture, the Guarantor will make such deduction or withholding, make payment of the amount so withheld to the appropriate governmental or other authority and pay such additional amounts as may be necessary to ensure that the net amounts receivable by Holders of Notes after such withholding or deduction shall equal the respective amounts of principal and interest which would have been receivable in respect of the Notes in the absence of such withholding or deduction (“Additional Amounts”). (b) The Substituted Issuer shall indemnify any Holder of Notes against all taxes or duties that arise by reason of a law or regulation in effect on the effective date of the Issuer Substitution that are incurred or levied against such Holder in Brazil as a result of the substitution, which would not have been so incurred or levied had the substitution not been made.
