<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 1in">The Treasury Rate shall be determined by the Company
after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors
of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent

Reserve System designated as &ldquo;Selected Interest Rates (Daily) - H.15&rdquo; (or any successor designation or publication) (&ldquo;H.15&rdquo;)
under the caption &ldquo;U.S. government securities&ndash;Treasury constant maturities&ndash;Nominal&rdquo; (or any successor caption
or heading). In determining the Treasury Rate, the Company shall select, as applicable: (1)&nbsp;the yield for the Treasury constant
maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the &ldquo;Remaining Life&rdquo;); or (2)&nbsp;if
there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields &ndash; one yield corresponding
to the Treasury constant maturity on H.15 immediately shorter than the Remaining Life and one yield corresponding to the Treasury constant
maturity on H.15 immediately longer than the Remaining Life &ndash; and shall interpolate to the Par Call Date on a straight-line basis
(using the actual number of days) using such yields and rounding the result to three decimal places; or (3)&nbsp;if there is no such
Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity
on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15
shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity
from the redemption date.</P>

date H.15 or any successor designation or publication is no longer published, the Company shall calculate the Treasury Rate based on
the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day
preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call
Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States
Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date
and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity
date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or
more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two
or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of
the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate
in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall
be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time,
of such United States Treasury security, and rounded to three decimal places. The Company&rsquo;s actions and determinations in determining
the redemption price shall be conclusive and binding for all purposes, absent manifest error.</P>

Means. The Trustee shall have the right to accept and act upon instructions, including funds transfer instructions (&ldquo;Instructions&rdquo;)
given pursuant to this Sixth Supplemental Indenture and related documents and delivered using Electronic Means; provided, however, that
the Company and/or Petrobras, as applicable, shall provide to the Trustee an incumbency certificate listing officers with the authority
to provide such Instructions (&ldquo;Authorized Officers&rdquo;) and containing specimen signatures of such Authorized Officers, which
incumbency certificate shall be amended by the Company and/or Petrobras, as applicable, whenever a person is to be added or deleted from

in its discretion elects to act upon such Instructions, the Trustee&rsquo;s understanding of such Instructions shall be deemed controlling.
The Company and Petrobras understand and agree that the Trustee cannot determine the identity of the actual sender of such Instructions
and that the Trustee shall conclusively presume that directions that purport to have been sent by an Authorized Officer listed on the
incumbency certificate provided to the Trustee have been sent by such Authorized Officer. The Company and Petrobras shall be responsible
for ensuring that only Authorized Officers transmit such Instructions to the Trustee and that the Company, Petrobras and all Authorized
Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or

or expenses arising directly or indirectly from the Trustee&rsquo;s reliance upon and compliance with such Instructions notwithstanding
such directions conflict or are inconsistent with a subsequent written instruction. The Company and Petrobras agree: (i)&nbsp;to assume
all risks arising out of the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of
the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii)&nbsp;that it is fully
informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there
may be more secure methods of transmitting Instructions than the method(s)&nbsp;selected by the Company and/or Petrobras, as applicable;
(iii)&nbsp;that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially
reasonable degree of protection in light of its particular needs and circumstances; and (iv)&nbsp;to notify the Trustee immediately upon
learning of any compromise or unauthorized use of the security procedures.</P>

duly executed and delivered by PGF and Petrobras, as applicable, in the forms thereof that we have examined, and the Notes have been duly
delivered to and paid for by the purchasers thereof in the manner described in the Registration Statement and executed and authenticated,
in the form thereof that we have examined, in accordance with the terms of the Indenture, the Notes will be valid, binding and enforceable
obligations of PGF, entitled to the benefits of the Indenture, and the Guaranty will be valid, binding and enforceable obligations of

and each other party to such agreement or obligation has satisfied those legal requirements that are applicable to it to the extent necessary
to make such agreement or obligation enforceable against it (except that no such assumption is made as to Petrobras and PGF regarding
matters of the federal law of the United States of America or the law of the State of New York that in our experience normally would be
applicable to general business entities in relation to transactions of the type contemplated in the Indenture and the Notes), (b) such
opinions are subject to applicable bankruptcy, insolvency and similar laws affecting creditors&rsquo; rights generally and to general
principles of equity, and (c) such opinions are subject to the effect of judicial application of foreign laws or foreign governmental
actions affecting creditors&rsquo; rights.</P>

Section 15 of the Guaranty and Section 1.15 of the 2018 Base Indenture by each of Petrobras and PGF, as applicable, of any immunities

Guaranty and Section 1.15 of the 2018 Base Indenture of any federal court in the Borough of Manhattan, the City of New York, State of
New York, as the venue for actions or proceedings relating to the Guaranty, the Indenture and the Notes, are (notwithstanding the waiver
in Section 15 of the Guaranty and Section 1.15 of the 2018 Base Indenture) subject to the power of such courts to transfer actions pursuant
to 28 U.S.C. &sect;1404(a) or to dismiss such actions or proceedings on the grounds that such a federal court is an inconvenient forum
