(i) The party making a claim under this Section 11.1 is referred to as the “Indemnified Party” and the party against whom such claims are asserted under this Section is referred to as the “Indemnifying Party”. The Indemnified Party shall promptly notify the Indemnifying Party in writing of any pending or threatened Third Party Claim that the Indemnified Party has determined, has given or would reasonably be expected to give rise to a right of indemnification under

this Agreement, describing in reasonable detail the facts and circumstances with respect to the subject matter of such Third Party Claim and, to the extent known, a good faith, non-binding, estimate of the aggregate Brazilian Reais amount of Losses to which such Indemnified Party might be entitled; provided, however, that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations under this Section 11.1 except to the extent the Indemnifying Party is actually and materially prejudiced by such failure.

(ii) Upon receipt of a notice of a claim for indemnity from an Indemnified Party pursuant to Section 11.1(c)(i), the Indemnifying Party will be entitled to assume the defense and control of any Third Party Claim with counsel reasonably acceptable to the Indemnified Party (acting reasonably), but shall allow the Indemnified Party a reasonable opportunity to participate in the defense of such Third Party Claim with the Indemnified Party’s own counsel and at the Indemnified Party’s own expense. If the Indemnifying Party does not assume the defense and control of any Third Party Claim, it may nonetheless participate in the defense of such Third Party Claim with its own counsel and at its own expense. The Indemnified Party shall reasonably cooperate with the Indemnifying Party in the defense of any Third Party Claim. If the Indemnifying Party shall have assumed the defense and control of a Third Party Claim, it shall be authorized to consent to a settlement of, or the entry of any judgment arising from, any Third Party Claim; provided that the Indemnifying Party shall (i) subject to any right of appeal, pay or cause to be paid all amounts in such settlement or judgment, (ii) not encumber any of the assets of any Indemnified Party or agree to any restriction or condition that would apply to or adversely affect any Indemnified Party or the conduct of any Indemnified Party’s business and (iii) obtain, as a condition of any settlement or other resolution, a complete release of any Indemnified Party potentially affected by such Third Party Claim. The Indemnified Party will not consent to the entry of any judgment or enter into any settlement or compromise with respect to a Third Party Claim without the prior written consent of the Indemnifying Party, such consent not to be unreasonably, withheld, conditioned or delayed.

Section 11.2 Mitigation. Notwithstanding anything to the contrary contained in this Agreement, nothing in this ARTICLE XI (Indemnification), regarding indemnification rights and indemnification obligations shall be deemed to override any obligations with respect to mitigation of Losses existing under applicable Legal Requirements.
