 Interest and additional amounts
(if any) will constitute income from sources without the United States and, for U.S. holders that elect to claim foreign tax credits,
generally will constitute “passive category income” for foreign tax credit purposes.

The availability and calculation
of foreign tax credits and deductions for foreign taxes depend on a U.S. holder’s particular circumstances and involve the application
of complex rules to those circumstances. The temporary guidance discussed above also indicates that the Treasury and the IRS are
considering proposing amendments to the December 2021 regulations and that the temporary guidance can be relied upon until additional
guidance is issued that withdraws or modifies the temporary guidance. U.S. holders should consult their own tax advisors regarding the
application of these rules to their particular situations.

Sale, Exchange and Retirement of Notes

Upon the sale, exchange or
retirement of a Note, a U.S. holder generally will recognize gain or loss equal to the difference between the amount realized on the sale,
exchange or retirement (less any accrued interest, which will be taxable as such) and the U.S. holder’s tax basis in such Note.
A U.S. holder’s tax basis in a note will generally equal the cost of the Note to such holder. Gain or loss recognized by a U.S.
holder generally will be long-term capital gain or loss if the U.S. holder has held the Note for more than one year at the time of disposition.
Long-term capital gains recognized by an individual holder generally are subject to tax at a lower rate than short-term capital gains
or ordinary income. The deduction of capital losses is subject to limitations.

A U.S. holder generally will
not be entitled to credit any Brazilian tax imposed on the sale or other disposition of the Notes against such U.S. holder’s U.S.
federal income tax liability, except in the case of a U.S. holder that consistently elects to apply a modified version of the U.S. foreign
tax credit rules that is permitted under temporary guidance and complies with the specific requirements set forth in such guidance.
Additionally, capital gain or loss recognized by a U.S. holder on the sale or other disposition of the Notes generally will be U.S. source
gain or loss for U.S. foreign tax credit purposes. Consequently, even if the withholding tax qualifies as a creditable tax, a U.S. holder
may not be able to credit the tax against its U.S. federal income tax liability unless
