“Payment Account”) into which all payments required to be made by the Company under or with respect to the Notes shall be deposited. The Company agrees that the Payment Account shall be maintained in the name of the Trustee and
under its sole dominion and control (acting on behalf of the Holders of the Notes) and used solely to make payments of principal, interest and other amounts from time to time due and owing on, or with respect to, the Notes. No funds contained in the
Payment Account shall be used for any other purpose or in any manner not expressly provided for herein nor shall the Company or any other Person have an interest therein or amounts on deposit therein. All amounts on deposit in the Payment Account on
any Interest Payment Date after the Trustee has paid all amounts due and owing to the holders of the Notes as of such Interest Payment Date shall be retained in the Payment Account and used by the Trustee to pay any amounts due and owing to the
Holders of the Notes on the next succeeding Interest Payment Date. 












 (h) Form and Denomination: The Notes shall be issuable in whole in
the registered form of one or more Global Notes (without coupons), in minimum denominations of U.S.$2,000 and integral multiples of U.S.$1,000 in excess thereof, and shall be transferable in integral multiples of U.S.$2,000 and integral multiples of
U.S.$1,000 in excess thereof and the Depository for such Global Notes shall be The Depository Trust Company, New York, New York. 

(i) Guaranty: The Notes shall have the benefit of the Guaranty in the manner provided in Article 3 of this Second
Supplemental Indenture. 
 (j) Rating: The Notes can be issued without the requirement that they have any rating from
a nationally recognized statistical rating organization. 
 (k) Optional Early Redemption at Par: The Company
will have the right at its option to redeem the Notes, in whole or in part, at any time or from time to time on or after the Notes Par Call Date, on at least 15 days’ but not more than 60 days’ notice, at a Redemption Price equal to 100%
of the principal amount of the Notes to be redeemed plus accrued and unpaid interest on the principal amount of such Notes to the Redemption Date. 

(l) Optional Early Redemption With “Make-Whole” Amount. The Company will have the right at its option to
redeem the Notes, in whole or in part, at any time or from time to time prior to the Notes Par Call Date, on at least 15 days’ but not more than 60 days’ notice, at a Redemption Price equal to the greater of (A) 100% of the principal
amount of such Notes and (B) the sum of the present values of each remaining scheduled payment of principal and interest thereon that would be due after the Redemption Date as if the Notes were redeemed on the Notes Par Call Date (exclusive of
interest accrued to the date of redemption) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the
Treasury Rate plus 50 basis points (the “Make-Whole Amount”), plus in each case accrued and unpaid interest on the principal amount of such Notes to (but not including) the Redemption Date. 

(m) Redemption Notice. A redemption notice may at the Company’s option be subject to the satisfaction of one or
more conditions precedent, and such notice may be rescinded or the applicable Redemption Date delayed in the event that any or all such conditions shall not have been satisfied by the applicable Redemption Date. Any conditions precedent shall be
described in such notice. 
 (n) Early Redemption for Tax Reasons. The Notes may be redeemed at the option of the
Company, in whole but not in part, at any time at a Redemption Price equal to the principal amount thereof plus accrued and unpaid interest to the Redemption Date if and when, as a result of any change in, execution of, or amendment to, any laws or
regulations or ruling promulgated thereunder of the jurisdiction in which the Company is 












 
incorporated (or, in the case of a successor Person to the Company, of the jurisdiction in which such successor Person is organized or any political subdivision or taxing authority thereof or
therein) or the official entry or any change in the official application or interpretation of such laws, regulations or rulings, or any change in the official application of or interpretation of, or any execution of or amendment to, any treaty or
treaties affecting taxation to which such jurisdiction or such political subdivision or taxing authority (or such other jurisdiction or political subdivision or taxing authority) is a party, which change, execution or amendment becomes effective on
or after the date hereof (or in the case of a successor Person to the Company, the date on which such successor Person became such pursuant to Section 8.01 and 8.02 of the Original Indenture), the Company would be required to pay Additional
Amounts pursuant to Section 10.10 of the Original Indenture. For the avoidance of doubt, the Company shall have the option to so redeem the Notes in the event that it is required to pay Dutch Withholding Tax Act 2021 Additional Amounts;
provided, however, that the Company shall take reasonable measures to avoid any withholding tax on interest payments under the Notes as per the Dutch Withholding Tax Act 2021 directly resulting from the purchase by the Company or its
affiliates of any Notes; provided, further, that prior to giving the notice of redemption of the Notes (A) the Company or its successor shall deliver to the Trustee a Director’s Certificate to the effect that the obligations of the
Company or its successor to pay Dutch Withholding Tax Act 2021 Additional Amounts cannot be avoided by the Company or its successor taking reasonable measures available to it, and (B) the Company or its successor shall deliver to the Trustee an
Opinion of Counsel stating that the Company or its successor would be obligated to pay Dutch Withholding Tax 2021 Additional Amounts. The Trustee shall accept such Director’s Certificate and Opinion of Counsel as sufficient evidence of the
satisfaction of the conditions precedent set forth above, and shall be conclusive and binding on the Holders. For purposes of Section 11.08 of the Original Indenture, the reincorporation of the Company shall be treated as the adoption of a
successor entity, provided, however, that redemption under Section 11.08 of the Original Indenture shall not be available if the reincorporation was performed in anticipation of a change in, execution of or amendment to any laws or treaties or
the official application or interpretation of any laws or treaties of such new jurisdiction of incorporation that would result in an obligation to pay Additional Amounts. 

(o) Conversion: The Notes will not be convertible into, or exchangeable for, any other securities. 

(p) Except as described in Sections 2.05, the Notes will be subject to the covenants provided in Article 10 of the Original
Indenture. 












 Section 2.02. Amendments Relating to the Appointment of Agent for Service. As it
applies to the Notes, the first two sentences of Section 1.15 of the Original Indenture shall be replaced by the following:

Manhattan, The City of New York, State of New York, arising out of or relating to the Securities or this Indenture, but for that purpose only. Service of process upon such agent at the office of Petrobras America Inc. at 10350 Richmond Ave., Suite

delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.09, for all purposes of this Indenture such Security shall be deemed never to
have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.”
