 pay interest by mailing checks. Interest on global
securities will be paid to the holder thereof by wire transfer of same-day funds.

Holders buying and selling debt securities must
work out between themselves how to compensate for the fact that we will pay all the interest for an interest period to, in the case of
registered debt securities, the one who is the registered holder on the regular record date. The most common manner is to adjust the sales
price of the debt securities to pro-rate interest fairly between the buyer and seller. This pro-rated interest amount is called “accrued
interest.”

Street name and other indirect holders should consult their banks or brokers for information on how they will receive payments.

We may also arrange for additional payment offices,
and may cancel or change these offices, including our use of the trustee’s corporate trust office. These offices are called “paying
agents.” We may appoint paying agents outside the United States for a specific issuance of securities. We may also choose to act
as our own paying agent. We must notify you of changes in the paying agents for the debt securities of any series that you hold. (Petrobras Section 10.02; PGF Section 10.03)

Notices

We and the trustee will send notices only to direct
holders, using their addresses as listed in the registrar’s records. (Petrobras Section 1.06; PGF Section 1.06)

Regardless of who acts as paying agent, all money
that we pay to a paying agent that remains unclaimed at the end of two years after the amount is due to direct holders will be repaid
to us. After that two-year period, direct holders may look only to us for payment and not to the trustee, any other paying agent or anyone
else. (Petrobras Section 10.03, PGF Section 10.08)

Mergers and Similar Events

Under the indentures, except as described below,
we are generally permitted to consolidate, spin off, or merge with another entity. We are also permitted to sell or lease substantially
all of our assets to another entity or to buy or lease substantially all of the assets of another entity. No vote by holders of debt securities
approving any of these actions is required, unless as part of the transaction we make changes to the indentures requiring your approval,
as described later under “—Modification and Waiver.” We may take these actions as part
