supplementa prospectus pursuant to Article 23 of the Prospectus Regulation, in 
each case in relation to such offer.

Neither PGF nor the underwritershave authorized, nor do they authorize, the

investor as definedin the Prospectus Regulation. Neither PGF nor the 
underwriters have authorized, nor do they authorize, the making of any offer 
of Notesthrough any financial intermediary, other than offers made by the

                                       would have received without such withholding or deduction, subject to certain
                                       exceptions. In the event Petrobras is obligated to make payments to the      
                                       holders under the guaranty, Petrobras will pay such additional amounts as

                                  RISK FACTORS                                  

Our
2023 Form 20-F
includes extensive risk factors relating to our operations, our compliance and 
control risks, our relationship withthe Brazilian federal government, and to 
Brazil. You should carefully consider those risks and the risks described 
below, as well asthe other information included or incorporated by reference 
in this prospectus supplement and the accompanying prospectus, before makinga 
decision to invest in the Notes
.

Risks Relating to PGF's Debt Securities

The market for theNotes may not be liquid.

The Notes are an issuanceof new securities with no established trading market. 
We intend to apply to list the Notes on the NYSE. We can provide no assurance 
asto the liquidity of trading markets for the Notes offered by this prospectus 
supplement. We cannot guarantee that holders of the Noteswill be able to sell 
their Notes in the future. If a market for the Notes does not develop, holders 
of the Notes may not be able to resellthe Notes for an extended period of 
time, if at all.

Restrictions on themovement of capital out of Brazil may impair your ability 
to receive payments on the guaranty and restrict Petrobras's abilityto make 
payments to PGF in U.S. dollars.

In the past, the Brazilianeconomy has experienced balance of payment deficits 
and shortages in foreign exchange reserves, and the government has responded 
by restrictingthe ability of Brazilian or foreign persons or entities to 
convert
reais
into foreign currencies. The government may institutea restrictive exchange 
control policy in the future. Any restrictive exchange control policy could 
prevent or restrict our access toU.S. dollars, and consequently our ability to 
meet our U.S. dollar obligations under the guaranty and could also have a 
material adverseeffect on our business, financial condition and results of 
operations. We cannot predict the impact of any such measures on the 
Brazilianeconomy. In the event that any such restrictive exchange control 
policies were instituted by the Brazilian government, we may face 
adverseregulatory consequences in the Netherlands that may lead us to redeem 
the Notes prior to their maturity.

In addition, payments byPetrobras under the guaranty in connection with PGF's 
Notes do not currently require approval by or registration with the 
CentralBank of Brazil. The Central Bank of Brazil may nonetheless impose prior 
approval requirements on the remittance of U.S. dollars, whichcould cause 
delays in such payments.

Petrobras would berequired to pay judgments of Brazilian courts enforcing its 
obligations under the guaranty only in reais.

If proceedings were broughtin Brazil seeking to enforce Petrobras's 
obligations in respect of the guaranty, Petrobras would be required to 
discharge its obligationsonly in
reais
. Under Brazilian exchange controls, an obligation to pay amounts denominated 
in a currency other than
reais
,which is payable in Brazil pursuant to a decision of a Brazilian court, will 
be satisfied in
reais
at the rate of exchange ineffect on the date of payment, as determined by the 
Central Bank of Brazil.

A finding that Petrobrasis subject to U.S. bankruptcy laws and that any of the 
guaranty executed by it was a fraudulent conveyance could result in the 
relevantPGF noteholders losing their legal claim against Petrobras.

PGF's obligation tomake payments on the Notes is supported by Petrobras's 
obligation under the guaranty. Petrobras has been advised by its externalU.S. 
counsel that the guaranty is valid and enforceable in accordance with the laws 
of the State of New York and the United States. Inaddition, Petrobras has been 
advised by its general counsel that the laws of Brazil do not prevent the 
guaranty from being valid, bindingand enforceable against Petrobras in 
accordance with their terms.

In the event that U.S. federalfraudulent conveyance or similar laws are 
applied to the guaranty, and Petrobras, at the time it entered into the 
guaranty:


 . was or is insolvent or rendered insolvent by reason of our entry into such guaranty;



                                       S-                                       
                                       14                                       



 . was or is engaged in business or transactions for which the assets 
   remaining with Petrobras constituted unreasonably small capital; or



 . intended to incur or incurred, or believed or believe that Petrobras would   
   incur, debts beyond Petrobras's ability to pay such debts as they mature; and



 . in each case, intended to receive or received less than the reasonably equivalent value or fair consideration therefor,


then Petrobras's obligations under theguaranty could be avoided, or claims 
with respect to that agreement could be subordinated to the claims of other 
creditors. Among otherthings, a legal challenge to the guaranty on fraudulent 
conveyance grounds may focus on the benefits, if any, realized by Petrobras 
asa result of the issuance of the Notes. To the extent that the guaranty is 
held to be a fraudulent conveyance or unenforceable for anyother reason, the 
holders of the Notes would not have a claim against Petrobras under the 
guaranty and would solely have a claim againstPGF. Petrobras cannot ensure 
that, after providing for all prior claims, there will be sufficient assets to 
satisfy the claims of thenoteholders relating to any avoided portion of the 
guaranty.

We cannot assure youthat the credit ratings for the Notes will not be lowered, 
suspended or withdrawn by the rating agencies.

The credit ratings of theNotes may change after issuance. Such ratings are 
limited in scope, and do not address all material risks relating to an 
investment inthe Notes, but rather reflect only the views of the rating 
agencies at the time the ratings are issued. An explanation of the 
significanceof such ratings may be obtained from the rating agencies. We 
cannot assure you that such credit ratings will remain in effect for anygiven 
period of time or that such ratings will not be lowered, suspended or 
withdrawn entirely by the rating agencies, if, in the judgmentof such rating 
agencies, circumstances so warrant. Any lowering, suspension or withdrawal of 
such ratings may have an adverse effecton the market price and marketability 
of the Notes.

Risks Relating to PGF and Petrobras

PGF's operationsand debt servicing capabilities are dependent on Petrobras.

PGF's financial positionand results of operations are directly affected by 
Petrobras's decisions. PGF is an indirect, wholly-owned finance subsidiary 
ofPetrobras incorporated in the Netherlands as a private company with limited 
liability. PGF does not currently have any operations, revenuesor assets other 
than those related to its primary business of raising money for the purpose of 
on-lending to Petrobras and other subsidiariesof Petrobras. PGF's ability to 
satisfy its obligations under the Notes will depend on payments made to PGF by 
Petrobras and othersubsidiaries of Petrobras under the loans made by PGF. The 
Notes and all debt securities issued by PGF will be fully and unconditionallygua
ranteed by Petrobras. Petrobras's financial condition and results of 
operations, as well as Petrobras's financial supportof PGF, directly affect 
PGF's operational results and debt servicing capabilities.

                                USE OF PROCEEDS                                 

The net proceeds from thesale of the Notes, after payment of the underwriting 
discount but before expenses, are expected to be approximately U.S.$        
million.

PGFintends to use the net proceeds from the sale of the Notes
to purchase the Old Notes that PGF accepts for purchase in the TenderOffers 
announced concurrently with this offering, and to use any remaining net 
proceeds for general corporate purposes.

Theunderwriters are acting as dealer managers in connection with the Tender 
Offers and will receive a commission for also acting in suchcapacity.
In addition, the underwriters or their affiliates may tender Old Notes in the 
Tender Offers for their own account orfor the accounts of their customers, in 
which case the underwriters, their affiliates or customers may receive a 
portion of the proceedsof this offering. See "The Offering-Tender Offers."

Appointment to Filla Vacancy in Office of Trustee

will appoint a successor trustee in the manner provided in the indenture so

other governmental charges of any nature imposed by Brazil, the jurisdiction 
of PGF's incorporation (currently the Netherlands)or any jurisdiction in which 
PGF appoints a paying agent under the indenture, or any political subdivision 
of such jurisdictions (the"taxing jurisdictions"). If PGF or Petrobras, as 
applicable, is required by law to withhold or deduct any such taxes, 
levies,deductions or other governmental charges, PGF or Petrobras, as 
applicable, will make such deduction or withholding, make payment of theamount 
so withheld to the appropriate governmental authority and pay the holders any 
additional amounts necessary to ensure that theyreceive the same amount as 
they would have received without such withholding or deduction. For the 
avoidance of doubt, the foregoingobligations shall extend to payments under 
the guaranty.

   charge, (ii) the holder is able to comply with such requirements without undue hardship and (iii) at      
   least 30 calendar days prior to the first payment date with respect to which such requirements under the

                                       S-

   provided that                                                                                                    
   PGF or Petrobras, as applicable, will pay additional amounts which a holder would have been entitled to had the  
   Notes owned by such holder been presented on any day (including the last day) within such 30 calendar day period;

   Wet bronbelasting 2021

levies payable by PGF as provided in this paragraph paid by such holder. As 
provided in"-Payments and Paying Agents," all payments in respect of the Notes 
will be made subject to any withholding or deductionrequired pursuant to 
FATCA, and we will not be required to pay any additional amounts on account of 
any such deduction or withholdingrequired pursuant to FATCA.

Negative Pledge

lien, other than a PGF permitted lien, on any of its assets to secure (i) any

contemporaneously creates or permits such lien to secureequally and ratably 
its obligations under the Notes as is duly approved by a resolution of the 
holders of the Notes in accordance withthe indenture. In addition, PGF will 
not allow any of its material subsidiaries, if any, to create or permit any 
lien, other than a PGFpermitted lien, on any of its assets to secure (i) any 
of its indebtedness; (ii) any of the material subsidiary's indebtednessor 
(iii) the indebtedness of any other person, unless it contemporaneously 
creates or permits the lien to secure equally and ratablyits obligations under 
the Notes and the indenture or PGF provides such other security for the Notes 
and the indenture as is duly approvedby a resolution of the holders of the 
Notes in accordance with such indenture. This covenant is subject to a number 
of important exceptions,including an exception that permits PGF to grant liens 
in respect of indebtedness the principal amount of which, in the aggregate, 
togetherwith all other liens not otherwise described in a specific exception, 
does not exceed 20% of PGF's consolidated total assets (asdetermined in

substantiallyall of its properties, assets or revenues to any person or entity 
(other than a direct or indirect subsidiary of Petrobras) or permitany person 
(other than a direct or indirect subsidiary of PGF) to merge with or into it

properties, assets or revenues does not violate any provision of Dutch 
financial regulatory laws and:


 . either PGF is the continuing entity or the person (the "successor company") formed by the consolidation or into which   
   PGF is merged or that acquired (through a transfer of assets, a spin-off or otherwise) or leased the property or assets 
   of PGF will assume (jointly and severally with PGF unless PGF will have ceased to exist as a result of that merger,     
   consolidation or amalgamation), by a supplemental indenture, all of PGF's obligations under the indenture and the Notes;



                                       S-

 . the successor company (jointly and severally with PGF unless PGF will have ceased to exist as part of the      
   merger, consolidation or amalgamation) agrees to indemnify each holder against any tax, assessment or          
   governmental charge thereafter imposed on the holder solely as a consequence of the consolidation, merger,     
   conveyance, spin-off, transfer or lease with respect to the payment of principal of, or interest on, the Notes;

   of its properties, assets or revenues to a direct or indirect subsidiary   
   of PGF or Petrobras in cases when PGF is the surviving entity in           
   the transaction and the transaction would not have a material adverse      
   effect on PGF and its subsidiaries taken as a whole, it being understood   
   that if PGF is not the surviving entity, PGF will be required to

certain covenants applicable to the Notes or any term, provision or condition 
of the indenture,if before the time for the compliance the holders of at least 
a majority of the principal amount of the outstanding Notes waive the

and, until a waiver becomes effective, PGF's obligations and theduties of the 
trustee in respect of any such term, provision or condition will remain in 
full force and effect.

Notices

For so long as Notes in globalform are outstanding, notices to be given to 
holders will be given to the Trustee in accordance with its applicable 
policies in effectfrom time to time. If Notes are issued in individual 
definitive form, notices to be given to holders will be deemed to have been 
givenupon the mailing by first class mail of such notices to holders of the 
Notes at their registered addresses as they appear in the registrar'srecords.


Optional Redemption

PGF will not be permittedto redeem the Notes before their stated maturity, 
except as set forth below. The Notes will not be entitled to the benefit of 
any sinkingfund (we will not deposit money on a regular basis into any 
separate account to repay your Notes). In addition, you will not be entitledto 
require us to repurchase your Notes from you before the stated maturity.

On and after the redemptiondate, interest will cease to accrue on the Notes or 
any portion of the Notes called for redemption (unless we default in the 
paymentof the redemption price and accrued and unpaid interest). On or before 
the business day prior to any redemption date, we will depositwith the trustee 
money sufficient to pay the redemption price of and (unless the redemption 
date shall be an interest payment date) accruedand unpaid interest to the 
redemption date on the Notes to be redeemed on such date. If less than all of 
the Notes are to be redeemed,the Notes to be redeemed shall be selected by the 
trustee by such method as set forth in the indenture.

Optional Redemptionat Par

PGF will have the right atour option to redeem the Notes, in whole or in part, 
at any time or from time to time on or after , 20 ( months prior to the 
scheduledmaturity date of the Notes) (the "Par Call Date"), on at least 10 
days' but not more than 60 days' notice, ata redemption price equal to 100% of 
the principal amount of the Notes to be redeemed plus accrued and unpaid 
interest on the principalamount of such Notes to the date of redemption.

Optional RedemptionWith "Make-Whole" Amount for the Notes

PGF will have the right atour option to redeem the Notes, in whole or in part, 
at any time or from time to time prior to the Par Call Date, on at least 10 
days'but not more than 60 days' notice, at a redemption price equal to the 
greater of (i) 100% of the principal amount of suchNotes and (ii) the sum of 
the present values of each remaining scheduled payment of principal and 
interest thereon that would bedue after the redemption date as if the Notes 
were redeemed on the Par Call Date 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 basis points, less interest accrued to the dateof 
redemption, plus in each case accrued and unpaid interest on the principal 
amount of such Notes to the date of redemption.


                                       S-                                       
                                       28                                       


A redemption notice may atPGF's option be subject to the satisfaction of one 
or more conditions precedent, and such notice may be rescinded or the 
redemptiondate delayed in the event that any or all such conditions shall not 
have been satisfied by the redemption date.

"Treasury Rate"means, with respect to any redemption date, the yield 
determined by PGF in accordance with the following two paragraphs.

The Treasury Rate shall bedetermined by PGF after 4:15 p.m., New York City 
time (or after such time as yields on U.S. government securities are posted 
daily bythe Board of Governors of the Federal Reserve System), on the third 
business day preceding the redemption date based upon the yield oryields for 
the most recent day that appear after such time on such day in the most recent 
statistical release published by the Boardof Governors of the Federal Reserve 
System designated as "Selected Interest Rates (Daily) - H.15" (or any 
successor designationor publication) ("H.15") under the caption "U.S. 
government securities-Treasury constant maturities-Nominal"(or any successor 
caption or heading). In determining the Treasury Rate, PGF shall select, as 
applicable: (1) the yield for theTreasury constant maturity on H.15 exactly 
equal to the period from the redemption date to the Par Call Date (the 
"Remaining Life");or (2) if there is no such Treasury constant maturity on 
H.15 exactly equal to the Remaining Life, the two yields - one yieldcorrespondin
g to the Treasury constant maturity on H.15 immediately shorter than the 
Remaining Life and one yield corresponding to theTreasury constant maturity on 
H.15 immediately longer than the Remaining Life - and shall interpolate to the 
Par Call Date on astraight-line basis (using the actual number of days) using 
such yields and rounding the result to three decimal places; or (3) ifthere is 
no such Treasury constant maturity on H.15 shorter than or longer than the 
Remaining Life, the yield for the single Treasuryconstant maturity on H.15 
closest to the Remaining Life. For purposes of this paragraph, the applicable 
Treasury constant maturity ormaturities on H.15 shall be deemed to have a 
maturity date equal to the relevant number of months or years, as applicable, 
of such Treasuryconstant maturity from the redemption date.

If on the third businessday preceding the redemption date H.15 or any 
successor designation or publication is no longer published, PGF shall 
calculate the TreasuryRate 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 secondbusiness 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 moreUnited States Treasury 
securities with a maturity date equally distant from the Par Call Date, one 
with a maturity date preceding thePar Call Date and one with a maturity date 
following the Par Call Date, PGF shall select the United States Treasury 
security with a maturitydate preceding the Par Call Date. If there are two or 
more United States Treasury securities maturing on the Par Call Date or two 
ormore United States Treasury securities meeting the criteria of the preceding 
sentence, PGF shall select from among these two or moreUnited States Treasury 
securities the United States Treasury security that is trading closest to par 
based upon the average of the bidand asked prices for such United States 
Treasury securities at 11:00 a.m., New York City time. In determining the 
Treasury Rate in accordancewith the terms of this paragraph, the semi-annual 
yield to maturity of the applicable United States Treasury security shall be 
basedupon 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 suchUnited States 
Treasury security, and rounded to three decimal places. PGF's actions and 
determinations in determining the redemptionprice shall be conclusive and 
binding for all purposes, absent manifest error.

On and after the redemptiondate, interest will cease to accrue on the Notes or 
any portion of the Notes called for redemption (unless we default in the 
paymentof the redemption price and accrued and unpaid interest). On or before 
the redemption date, we will deposit with the trustee money sufficientto pay 
the redemption price of and (unless the redemption date shall be an interest 
payment date) accrued and unpaid interest to theredemption date on the Notes 
to be redeemed on such date. If less than all of the Notes are to be redeemed, 
the Notes to be redeemedshall be selected by the trustee by such method as set 
forth in the indenture.

Redemption for Taxation Reasons

We have the option, subjectto certain conditions, to redeem the Notes in whole 
at their principal amount, plus accrued and unpaid interest, if any, to the 
dateof redemption, if and when, as a result of a change in, execution of, or 
amendment to, any laws or treaties or the official entry intoeffect, 
application or interpretation of any laws or treaties, we would be required to 
pay additional amounts related to the deductionof certain withholding taxes in 
respect of certain payments on the Notes.


                                       S-

The Optional Tax Redemptionset forth in the accompanying prospectus shall 
apply with the reincorporation of PGF being treated as the adoption of a 
successor entity.Such redemption shall not be available if the reincorporation 
was performed in anticipation of a change in, execution of or amendmentto any 
laws or treaties or the official application or interpretation of any laws or 
treaties in such new jurisdiction of incorporationthat would result in the 
obligation to pay additional amounts.

Amendments

See "Description of Debt Securities-SpecialSituations-Modification and Waiver" 
in the accompanying prospectus.

Further Issuances

The indenture by its termsdoes not limit the aggregate principal amount of 
securities that may be issued under it and permits the issuance, from time to 
time,of additional notes (also referred to as add-on Notes) of the same series 
as those offered under this prospectus supplement. The abilityto issue add-on 
Notes is subject to several requirements, however, including that (i) no event 
of default under the indenture orevent that with the passage of time or other 
action may become an event of default (such event being a "default") will 
haveoccurred and then be continuing or will occur as a result of that 
additional issuance, (ii) the add-on Notes will rank
pari passu
and have equivalent terms and benefits as the Notes offered under this 
prospectus supplement except for the price to the public andthe issue date and 
(iii) any add on Notes shall be issued under a separate CUSIP or ISIN number 
unless the add on Notes are issuedpursuant to a "qualified reopening" of the 
original series, are otherwise treated as part of the same "issue"of debt 
instruments as the original series or are issued with less than a
de minimis
amount of original discount, in each casefor U.S. federal income tax purposes. 
Any add-on Notes with respect to the Notes will be part of the same series as 
such Notes that PGFis currently offering and the holders will vote on all 
matters in relation to the Notes as a single series.

Covenant Defeasance

Any restrictive covenantsof the indenture may be defeased as described in the 
accompanying prospectus.

Conversion

The Notes will not be convertibleinto, or exchangeable for, any other 
securities.

Listing

PGF intends to apply to havethe Notes approved for listing on the NYSE.

Currency Rate Indemnity

PGF has agreed that, if ajudgment or order made by any court for the payment 
of any amount in respect of any Notes is expressed in a currency (the 
"judgmentcurrency") other than U.S. dollars (the "denomination currency"), PGF 
will indemnify the relevant holder and the trusteeagainst any deficiency 
arising from any variation in rates of exchange between the date as of which 
the denomination currency is notionallyconverted into the judgment currency 
for the purposes of the judgment or order and the date of actual payment. This 
indemnity will constitutea separate and independent obligation from PGF's 
other obligations under the indenture, will give rise to a separate and 
independentcause of action, will apply irrespective of any indulgence granted 
from time to time and will continue in full force and effect notwithstandingany 
judgment or order for a liquidated sum or sums in respect of amounts due in 
respect of the Note or under any judgment or order describedabove.


                                       S-

may be merged or converted or with which it may be consolidated, or any 
corporation orassociation resulting from any merger, conversion or 
consolidation to which the trustee or any agent shall be a party, or any 
corporationor association to which all or substantially all of the corporate 
trust business of the trustee or any agent may be sold or otherwisetransferred, 
shall be the successor trustee or relevant agent, as applicable, hereunder 
without any further act.

                          DESCRIPTION OF THE GUARANTY                           

General

In connection with the executionand delivery of the sixth supplemental 
indenture and the Notes offered by this prospectus supplement, Petrobras will 
guarantee the Notes(the "guaranty") for the benefit of the holders.

The guaranty will providethat Petrobras will unconditionally and irrevocably 
guarantee the Notes on the terms and conditions described below.

The following summary describesthe material provisions of the guaranty. You 
should read the more detailed provisions of the guaranty, including the 
defined terms, forprovisions that may be important to you. This summary is 
subject to, and qualified in its entirety by reference to, the provisions 
ofthe guaranty.

Despite the Brazilian government'sownership interest in Petrobras, the 
Brazilian government is not responsible in any manner for PGF's obligations 
under the Notesor Petrobras's obligations under the guaranty.

Ranking

The obligations of Petrobrasunder the guaranty will constitute general 
unsecured obligations of Petrobras which at all times will rank
pari passu
, withoutany preferences among themselves, with all other senior unsecured 
obligations of Petrobras that are not, by their terms, expressly subordinatedin 
right of payment to the obligations of Petrobras under the guaranty.

In addition, Petrobras'sobligations under the guaranty of the Notes rank, and 
will rank,
pari passu
with its obligations in respect of outstanding andfuture guaranties of 
indebtedness issued by PGF.

Nature of Obligation

Petrobras will unconditionallyand irrevocably guarantee (by way of a first 
demand guarantee) the full and punctual payment when due, whether at the 
maturity date ofthe Notes, or earlier or later by acceleration or otherwise, 
of all of PGF's obligations now or hereafter existing under the indentureand 
the Notes, whether for principal, interest, make-whole premium, fees, 
indemnities, costs, expenses, tax payments or otherwise (suchobligations being 
referred to as the "guaranteed obligations").

The obligation of Petrobrasto pay amounts in respect of the guaranteed 
obligations will be absolute and unconditional (thus waiving any benefits of 
order set forthunder Brazilian law, including those established in articles 
827, 834, 835, 838 and 839 of the Brazilian Civil Code, under article 
794,caput, of the Brazilian Civil Procedure Code) upon failure of PGF to make, 
at the maturity date of the Notes or earlier upon any accelerationor otherwise 
of the Notes in accordance with the terms of the indenture, any payment in 
respect of principal, interest or other amountsdue under the indenture and the 
Notes on the date any such payment is due. If PGF fails to make payments to 
the trustee in respect ofthe guaranteed obligations, Petrobras will, upon 
notice from the trustee, immediately pay to the trustee such amount of the 
guaranteedobligations payable under the indenture and the Notes. All amounts 
payable by Petrobras under the guaranty will be payable in U.S. dollarsand in 
immediately available funds to the trustee. Petrobras will not be relieved of 
its obligations under any guaranty unless and untilthe trustee receives all 
amounts required to be paid by Petrobras under such guaranty (and any related 
event of default under the indenturehas been cured), including payment of the 
total non-payment overdue interest.


                                       S-                                       
                                       32                                       


Events of Default

There are no events of defaultunder the guaranty. The sixth supplemental 
indenture, however, contains events of default relating to Petrobras that may 
trigger an eventof default and acceleration of the Notes. See "Description of 
the Notes―Events of Default." Upon any such acceleration(including any 
acceleration arising out of the insolvency or similar events relating to 
Petrobras), if PGF fails to pay all amounts thendue under the Notes and the 
indenture, Petrobras will be obligated to make such payments pursuant to the 
guaranty.

as applicable,to comply with the terms of the following covenants:

Petrobras will ensure atall times that its obligations under the guaranty will 
be its general senior unsecured and unsubordinated obligations and will rank

guaranty and the indenture, as applicable, andthat no event of default has 
occurred during such period.

In addition, whether or notPetrobras is required to file reports with the SEC,

allholders of the Notes, upon written request, of the Notes) all reports and 
other information it would be required to file with the SECunder the Exchange

filing described above, Petrobras willprovide annual and interim reports and 
other information to the trustee within the same time periods that would be 
applicable if Petrobraswere required and permitted to file these reports with 
the SEC.

Delivery of these reports,information and documents to the trustee is for 
informational purposes only and the trustee's receipt of any of those shall 
notconstitute constructive notice of any information contained in them or 
determinable from information contained therein, including Petrobras'scompliance

Amendments

The guaranty may only beamended or waived in accordance with its terms 
pursuant to a written document which has been duly executed and delivered by 
Petrobrasand the trustee, acting on behalf of the holders of the Notes. 
Because the guaranty forms part of the indenture, it may be amended 
byPetrobras and the trustee, in some cases without the consent of the holders 
of the Notes. See "Description of Debt Securities-SpecialSituations-Modification
 and Waiver" in the accompanying prospectus.

Except as contemplated above,the indenture will provide that the trustee may 
execute and deliver any other amendment to the guaranty or grant any waiver 
thereof onlywith the consent of the holders of a majority in aggregate 
principal amount of the Notes then outstanding.

Governing Law

The guaranty will be governedby the laws of the State of New York.

Jurisdiction

Under the guaranty, Petrobraswill consent to the non-exclusive jurisdiction of 
any court of the State of New York or any U.S. federal court sitting in the 
Boroughof Manhattan, The City of New York, New York, United States and any 
appellate court from any thereof.

Waiver of Immunities

To the extent that Petrobrasmay in any jurisdiction claim for itself or its 
assets immunity from a suit, execution, attachment, whether in aid of 
execution, beforejudgment or otherwise, or other legal process in connection 
with the guaranty (or any document delivered pursuant thereto) and to 
theextent that in any jurisdiction there may be immunity attributed to 
Petrobras, PGF or their assets, whether or not claimed, Petrobraswill 
irrevocably agree with the trustee under the guaranty, for the benefit of the 
holders, not to claim, and to irrevocably waive, theimmunity to the full 
extent permitted by law.

Currency Rate Indemnity

Under the guaranty, Petrobraswill agree that, if a judgment or order made by 
any court for the payment of any amount in respect of any of its obligations 
under theguaranty is expressed in a currency (the "judgment currency") other 
than U.S. dollars (the "denomination currency"),Petrobras will indemnify the 
relevant holder and the trustee against any deficiency arising from any 
variation in rates of exchange betweenthe date as of which the denomination 
currency is notionally converted into the judgment currency for the purposes 
of the judgment ororder and the date of actual payment. This indemnity will 
constitute a separate and independent obligation from Petrobras's 
otherobligations under the guaranty, will give rise to a separate and 
independent cause of action, will apply irrespective of any indulgencegranted 
from time to time and will continue in full force and effect.


                                       S-

                            CLEARANCE AND SETTLEMENT                            

Book-Entry Issuance

Except under the limitedcircumstances described in the accompanying 
prospectus, all Notes will be book-entry Notes. This means that the actual 
purchasers ofthe Notes will not be entitled to have the Notes registered in 
their names and will not be entitled to receive physical delivery of theNotes 
in definitive (paper) form. Instead, upon issuance, all the Notes will be 
represented by one or more fully registered global Notes.

Each of the Notes will berepresented by one or more global notes. Each global 
note will be deposited directly with The Depository Trust Company, a 
securitiesdepositary, and will be registered in the name of DTC's nominee. 
Global Notes may also be deposited indirectly with Clearstream,Luxembourg and 
Euroclear, as indirect participants of DTC. For background information 
regarding DTC and Clearstream, Luxembourg and Euroclear,see "-The Depository 
Trust Company" and "-Clearstream, Luxembourg and Euroclear" below. No 
globalnote representing book-entry Notes may be transferred except as a whole 
by DTC to a nominee of DTC, or by a nominee of DTC to anothernominee of DTC. 
Thus, DTC will be the only registered holder of the Notes and will be 
considered the sole representative of the beneficialowners of the Notes for 
purposes of the indenture. For an explanation of the situations in which a 
global note will terminate and interestsin it will be exchanged for physical 
certificates representing the Notes, see "Legal Ownership-Global Securities" 
inthe accompanying prospectus.

The registration of the globalnotes in the name of DTC's nominee will not 
affect beneficial ownership and is performed merely to facilitate subsequent 
transfers.The book-entry system, which is also the system through which most 
publicly traded common stock is held in the United States, is usedbecause it 
eliminates the need for physical movement of securities certificates. The laws 
of some jurisdictions, however, may requiresome purchasers to take physical 
delivery of their Notes in definitive form. These laws may impair the ability 
of beneficial holdersto transfer the Notes.

In this prospectus supplement,unless and until definitive (paper) Notes are 
issued to the beneficial owners as described in the accompanying prospectus, 
all referencesto "registered holders" of Notes shall mean DTC. PGF, Petrobras, 
the trustee and any paying agent, transfer agent, registraror other agent may 
treat DTC as the absolute owner of the Notes for all purposes.

Primary Distribution

Payment Procedures

Payment for the Notes willbe made on a delivery versus payment basis.

Clearance and Settlement Procedures

DTC participants that holdsecurities through DTC on behalf of investors will 
follow the settlement practices applicable to United States corporate debt 
obligationsin DTC's Same-Day Funds Settlement System. Notes will be credited 
to the securities custody accounts of these DTC participantsagainst payment in 
the same-day funds, for payments in U.S. dollars, on the settlement date.

Secondary Market Trading

We understand that secondarymarket trading between DTC participants will occur 
in the ordinary way in accordance with DTC's rules. Secondary market 
tradingwill be settled using procedures applicable to United States corporate 
debt obligations in DTC's Same-Day Funds Settlement System.If payment is made 
in U.S. dollars, settlement will be free of payment. If payment is made in 
other than U.S. dollars, separate paymentarrangements outside of the DTC 
system must be made between the DTC participants involved.

The Depository Trust Company

The policies of DTC willgovern payments, transfers, exchange and other matters 
relating to the beneficial owner's interest in the Notes held by that 
owner.Neither the Trustee, Registrar, Paying Agent and Transfer Agent nor we 
have any responsibility for any aspect of the actions of DTC orany of their 
direct or indirect participants. Neither the Trustee, Registrar, Paying Agent 
and Transfer Agent nor we have any responsibilityfor any aspect of the records 
kept by DTC or any of their direct or indirect participants. In addition, 
neither the Trustee, Registrar,Paying Agent and Transfer Agent nor we 
supervise DTC in any way. DTC and their participants perform these clearance 
and settlement functionsunder agreements they have made with one another or 
with their customers. Investors should be aware that DTC and its participants 
arenot obligated to perform these procedures and may modify them or 
discontinue them at any time. The description of the clearing systemsin this 
section reflects our understanding of the rules and procedures of DTC as they 
are currently in effect. DTC could changeits rules and procedures at any time.

The underwriting agreementprovides that the obligation of the underwriters to 
pay for and accept delivery of the Notes is subject to, among other 
conditions, thedelivery of certain certificates and legal opinions. The 
underwriters are offering the Notes, subject to prior sale, when, as and 
ifissued to and accepted by them. The underwriters are obligated to take and 
pay for all of the Notes offered by this prospectus supplementif any Notes are 
taken. The underwriting agreement also provides that if an underwriter 
defaults, the purchase commitments of the non-defaultingunderwriters may be 
increased or the offering of the Notes may be terminated. The Notes will 
initially be offered at the price indicatedon the cover page of this 
prospectus supplement. After the initial offering of the Notes, the offering 
price and other selling termsmay from time to time be varied by the 
underwriters. The Notes may be offered and sold through certain of the 
underwriters' affiliates.The underwriters reserve the right to withdraw, 
cancel or modify offers to the public and to reject orders in whole or in part.


The underwriting agreementprovides that PGF and Petrobras will indemnify the 
underwriters against certain liabilities, including liabilities under the U.S. 
SecuritiesAct of 1933, as amended ("Securities Act"), and will contribute to 
payments the underwriters may be required to make in respectof the 
underwriting agreement.

PGF has been advised by theunderwriters that the underwriters intend to make a 
market in the Notes as permitted by applicable laws and regulations. The 
underwritersare not obligated, however, to make a market in the Notes and any 
such market-making may be discontinued at any time at the sole discretionof 
the underwriters. In addition, such market-making activity will be subject to 
the limits imposed by the Exchange Act. Accordingly,no assurance can be given 
as to the liquidity of, or the development or continuation of trading markets 
for, the Notes.

In connection with this offering,the underwriters (or persons acting on their 
behalf) participating in this offering may engage in transactions that 
stabilize, maintainor otherwise affect the price of the Notes. Specifically, 
the underwriters (or persons acting on their behalf) may bid for and 
purchaseNotes in the open market to stabilize the price of the Notes. The 
underwriters (or persons acting on their behalf) may also over-allotthis 
offering, creating a short position, and may bid for and purchase Notes in the 
open market to cover the short position. These activitiesif carried out, will 
be carried out with a view to stabilize, maintain and support the market price 
of the Notes during the stabilizationperiod above market levels that may 
otherwise prevail. The underwriters are not required to engage in these 
activities, and these activitiesmay not necessarily occur.

Any stabilization actionmay begin on or after the date on which adequate 
public disclosure of the terms of the offer of the Notes is made and, if 
begun, maybe ended at any time, but it must end no later than 30 days after 
the date on which the issuer received the proceeds of the issue, orno later 
than 60 days after the date of allotment of the Notes, whichever is the 
earlier. Any stabilization action or over-allotmentmust be conducted by the 
relevant underwriters (or persons acting on their behalf) in accordance with 
all applicable laws and rules andwill be undertaken at the offices of the 
underwriters (or persons acting on their behalf) and on the NYSE or the 
over-the-counter market.


                                       S-

The underwriters and theiraffiliates have engaged in, and may in the future 
engage in, investment banking and other commercial dealings in the ordinary 
courseof business with Petrobras, PGF and their affiliates. They have 
received, or may in the future receive, customary fees and commissionsfor 
these transactions.

In addition, in the ordinarycourse of their business activities, the 
underwriters and their affiliates may make or hold a broad array of 
investments and activelytrade debt and equity securities (or related 
derivative securities) and financial instruments (including bank loans) for 
their own accountand for the accounts of their customers. Such investments and 
securities activities may involve securities and/or instruments of oursor our 
affiliates. In particular, certain of the underwriters and/or their affiliates 
may hold debt securities or other indebtednessissued by PGF, including 
indebtedness guaranteed by Petrobras, which may be repurchased or repaid with 
proceeds of this offering. Ifany of the underwriters or their affiliates has a 
lending relationship with us, certain of those underwriters or their 
affiliates routinelyhedge, and certain other of those underwriters or their 
affiliates may hedge, their credit exposure to us consistent with their 
customaryrisk management policies.  Typically, these underwriters and their 
affiliates would hedge such exposure by entering into transactionswhich 
consist of either the purchase of credit default swaps or the creation of 
short positions in our securities, including potentiallythe Notes offered 
hereby.  Any such credit default swaps or short positions could adversely 
affect future trading prices of theNotes offered hereby. The underwriters and 
their affiliates may also make investment recommendations and/or publish or 
express independentresearch views in respect of such securities or financial 
instruments and may hold, or recommend to clients that they acquire, long 
and/orshort positions in such securities and instruments.

The underwriters and/or theiraffiliates may acquire the Notes for their own 
accounts. Such acquisitions may have an effect on demand for and the price of 
the Notes.

Theexpenses of the offering, excluding the underwriting discount, are 
estimated to be U.S.$
million and will be borne by PGF. PGFhas agreed to reimburse the underwriters 
up to approximately U.S.$ for certain of their expenses relating to the 
offering, includingthe fees and disbursements of counsel to the underwriters. 
Such reimbursement is deemed underwriting compensation by the Financial 
IndustryRegulatory Authority Inc. (FINRA).

Petrobras has been advisedby the underwriters that they propose to offer the 
Notes initially at the public offering price set forth on the cover page of 
thisprospectus supplement and to dealers at that price less a selling 
concession not in excess of % of the principal amount of the Notes.After the 
initial public offering of the Notes, the public offering price and concession 
and discount to dealers may be changed.

We expect to deliver theNotes against payment for the Notes on or about , 
2024, which will be the eighth business day following the date of this 
prospectus supplement(such settlement being referred to as "T+8"). Under Rule 
15c6-1 of the Exchange Act, trades in the secondary marketgenerally are 
required to settle in one business day, unless the parties to such trade 
expressly agree otherwise. Accordingly, purchaserswho wish to trade the Notes 
prior to the date that is one business day prior to the delivery of the Notes 
will be required, by virtueof the fact that the Notes initially will settle in 
eighth business days (T+8), to specify alternative settlement arrangements to 
preventa failed settlement.

where it is legal to make these offers. The distribution of this prospectus

The following discussionsummarizes certain U.S. federal income, Brazilian and 
Dutch tax considerations that may be relevant to the ownership and 
dispositionof the Notes acquired in this offering at their original issue 
price. This summary does not describe all of the tax considerations thatmay be 
relevant to you or your situation, particularly if you are subject to special 
tax rules. You should consult your tax advisorsabout the tax consequences of 
holding the Notes, including the relevance to your particular situation of the 
considerations discussedbelow, as well as of any other tax laws. There 
currently is no income tax treaty between Brazil and the United States. 
Although Brazilianand U.S. tax authorities have had discussions that may 
culminate in such a treaty, we cannot make any assurances regarding whether 
orwhen such a treaty will enter into force or how it will affect holders of 
the Notes.

U.S. Federal Income Tax Considerations

Thefollowing is a summary of certain U.S. federal income tax considerations 
that may be relevant to a holder of a Note.
This summaryis based on provisions of the Internal Revenue Code of 1986, as 
amended (the "Code"), applicable Treasury regulations, laws,rulings and 
decisions now in effect, all of which are subject to change, possibly with 
retroactive effect. This summary deals only withbeneficial owners of Notes 
that will hold Notes as capital assets and acquired notes upon original 
issuance at their original issue price.This summary does not address 
particular tax considerations that may be applicable to investors that are 
subject to special tax rules,such as banks, tax-exempt entities, insurance 
companies, regulated investment companies, dealers in securities or 
currencies, tradersin securities electing to mark to market, persons that will 
hold Notes as a position in a "straddle" or conversion transaction,or as part 
of a "synthetic security" or other integrated financial transaction, entities 
taxed as partnerships or the partnerstherein, U.S. expatriates, nonresident 
alien individuals present in the United States for more than 182 days in a 
taxable year, or personsthat have a "functional currency" other than the U.S. 
dollar. Furthermore, this discussion does not address all of the U.S.federal 
income tax considerations that may be relevant to a potential investor whose 
Old Notes are repurchased in the Tender Offers,and such persons should consult 
their own tax advisors regarding the U.S. federal income tax consequences to 
them of the redemption oftheir Old Notes pursuant to the Tender Offers and the 
acquisition of the Notes pursuant to this offering.

This summary addresses only U.S. federal incometax consequences, and does not 
address consequences arising under state, local, foreign tax laws, the 
alternative minimum tax or theMedicare tax on net investment income or under 
special timing rules prescribed under section 451(b) of the Code. 
Investorsshould consult their own tax advisors in determining the tax 
consequences to them of holding Notes under such tax laws, as well as 
theapplication to their particular situation of the U.S. federal income tax 
considerations discussed below.

As used herein, a "U.S. holder" isa beneficial owner of a Note that is, for 
U.S. federal income tax purposes, a citizen or resident of the United States 
or a domesticcorporation or that otherwise is subject to U.S. federal income 
taxation on a net income basis in respect of the Note.

Tax Consequences to U.S. Holders of Holding and Disposing ofNotes

Payments of Interest and Additional Amounts.

Thegross amount of stated interest and additional amounts (
i.e.
, without reduction for withholding tax at the appropriate Brazilianwithholding 
tax rate applicable to the U.S. holder) will be taxable to a U.S. holder as 
ordinary interest income at the time it accruesor is actually or constructively 
received, in accordance with the holder
'
smethod of accounting for U.S. federal income tax purposes. It is expected, 
and this discussion assumes, that the Notes will be issuedwithout original 
issue discount ("OID") for U.S. federal income tax purposes. In general, 
however, if the Notes are issuedwith OID at or above a
de minimis
threshold, a U.S. holder will be required to include OID in gross income, as 
ordinary income,under a "constant-yield method" before the receipt of cash 
attributable to such income, regardless of the U.S. holder'sregular method of 
accounting for U.S. federal income tax purposes.


                                       S-                                       
                                       50                                       


Subject to generally applicable limitations andconditions, Brazilian interest 
withholding tax (if any) paid at the appropriate rate applicable to the U.S. 
holder may be eligible forcredit against such U.S. holder's U.S. federal 
income tax liability. These generally applicable limitations and conditions 
includenew requirements adopted by the IRS in regulations promulgated in 
December 2021 and any Brazilian tax will need to satisfy theserequirements in 
order to be eligible to be a creditable tax for a U.S. holder. In the case of 
a U.S. holder that consistently electsto apply a modified version of these 
rules under recently issued temporary guidance and complies with specific 
requirements setforth in such guidance, any Brazilian tax on interest 
generally will be treated as meeting the new requirements and therefore as a 
creditabletax. In the case of all other U.S. holders, the application of these 
requirements to any Brazilian tax on interest is uncertain and wehave not 
determined whether these requirements have been met. If the Brazilian interest 
tax is not a creditable tax or the U.S. holderdoes not elect to claim a 
foreign tax credit for any foreign income taxes paid or accrued in the same 
taxable year, the U.S. holder maybe able to deduct the Brazilian tax in 
computing such U.S. holder's taxable income for U.S. federal income tax 
purposes. Interestand additional amounts (if any) will constitute income from 
sources without the United States and, for U.S. holders that elect to 
claimforeign tax credits, generally will constitute "passive category income" 
for foreign tax credit purposes.

The availability and calculation of foreign taxcredits and deductions for 
foreign taxes depend on a U.S. holder's particular circumstances and involve 
the application of complexrules to those circumstances. The temporary guidance 
discussed above also indicates that the Treasury and the IRS are consideringprop
osing amendments to the December 2021 regulations and that the temporary 
guidance can be relied upon until additional guidanceis issued that withdraws 
or modifies the temporary guidance. U.S. holders should consult their own tax 
advisors regarding the applicationof 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'stax 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 willbe 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 capitalgains 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 entitledto credit any Brazilian tax 
imposed on the sale or other disposition of the Notes against such U.S. 
holder's U.S. federal incometax liability, except in the case of a U.S. holder 
that consistently elects to apply a modified version of the U.S. foreign tax 
creditrules that is permitted under recently issued 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. sourcegain or loss for U.S. 
foreign tax credit purposes. Consequently, even if the withholding tax 
qualifies as a creditable tax, a U.S. holdermay not be able to credit the tax 
against its U.S. federal income tax liability unless such credit can be 
applied (subject to generallyapplicable conditions and limitations) against 
tax due on other income treated as derived from foreign sources. If the 
Brazilian taxis not a creditable tax, the tax would reduce the amount realized 
on the sale or other disposition of the Notes even if the U.S. holderhas 
elected to claim a foreign tax credit for other taxes in the same year. The 
temporary guidance discussed above also indicates thatthe Treasury and the IRS 
are considering proposing amendments to the December 2021 regulations and that 
the temporary guidance canbe relied upon until additional guidance is issued 
that withdraws or modifies the temporary guidance. U.S. holders should consult 
theirown tax advisors regarding the application of the foreign tax credit 
rules to a sale or other disposition of the Notes and any Braziliantax imposed 
on such sale or disposition.

Specified Foreign Financial Assets.

Individual U.S. holders that own "specifiedforeign financial assets" with an 
aggregate value in excess of $50,000 on the last day of the taxable year or 
$75,000 at any timeduring the taxable year are generally required to file an 
information statement along with their tax returns, currently on Form 
8938,with respect to such assets. "Specified foreign financial assets" include 
any financial accounts held at a non-U.S. financialinstitution, as well as 
securities issued by a non-U.S. issuer (which may include Notes issued in 
certificated form) that are not heldin accounts maintained by financial 
institutions. Higher reporting thresholds apply to certain individuals living 
abroad and to certainmarried individuals. Regulations extend this reporting 
requirement to certain entities that are treated as formed or availed of to 
holddirect or indirect interests in specified foreign financial assets based 
on certain objective criteria. U.S. holders who fail to reportthe required 
information could be subject to substantial penalties. In addition, the 
statute of limitations for assessment of tax wouldbe suspended, in whole or 
part.  Prospective investors should consult their own tax advisors concerning 
the application of theserules to their investment in the Notes, including the 
application of the rules to their particular circumstances.

Information Reporting and Backup Withholding

Information returns will be filed with the IRSin connection with payments on 
the Notes made to, and the proceeds of dispositions of Notes effected by, 
certain U.S. holders. In addition,certain U.S. holders may be subject to 
backup withholding in respect of such amounts if they do not provide their 
taxpayer identificationnumbers to the person from whom they receive payments. 
Investors who are not "United States persons" (as defined in the Code)may be 
required to comply with applicable certification procedures to avoid the 
application of such information reporting requirementsand backup withholding. 
The amount of any backup withholding from a payment to a holder will be 
allowed as a credit against the holder'sU.S. federal income tax liability and 
may entitle the holder to a refund, provided that the required information is 
timely furnishedto the IRS.

Brazilian Tax Considerations

The following discussionis a summary of the Brazilian tax considerations 
relating to an investment in the Notes by a non-resident of Brazil. This 
discussionis based on the tax laws of Brazil as in effect on the date of this 
prospectus supplement and is subject to any change in Brazilian lawthat may 
come into effect after such date. The information set forth below is intended 
to be a general discussion only and does not addressall possible tax 
consequences relating to an investment in the Notes.

PROSPECTIVEINVESTORS SHOULD CONSULT THEIR OWN TAX ADVISERS AS TO THE 
CONSEQUENCES OF PURCHASING THE NOTES, INCLUDING, WITHOUT LIMITATION, 
THECONSEQUENCES OF THE RECEIPT OF INTEREST AND THE SALE OR OTHER DISPOSITION 
OF THE NOTES OR COUPONS
.

Payments in Respect of the Notes, and Saleor Other Disposition of Notes

Generally, an individual,entity, trust or organization that is domiciled for 
tax purposes outside Brazil (a "Non-Resident") is subject to income taxin 
Brazil only when income is derived from a Brazilian source or when the 
transaction giving rise to such earnings involves assets locatedin Brazil. 
Therefore, based on the fact that PGF is considered to be domiciled abroad for 
tax purposes, any interest, gains, fees, commissions,expenses and any other 
income paid by PGF in respect of the Notes it issues to Non-Resident holders 
should not be subject to withholdingor deduction in respect of Brazilian 
income tax or any other taxes, duties, assessments or governmental charges in 
Brazil, provided thatsuch payments are made by PGF with funds held outside of 
Brazil.

Any capital gains generatedoutside Brazil as a result of a transaction between 
two Non-Resident holders with respect to assets not located in Brazil are 
generallynot subject to tax in Brazil. If the assets are located in Brazil, 
then capital gains realized thereon are subject to income tax, accordingto Law 
No. 10,833, enacted on December 29, 2003. Since the Notes will be issued by a 
legal entity incorporated outside of Braziland registered abroad, the Notes 
should not fall within the definition of assets located in Brazil for purposes 
of Law No. 10,833,gains realized on the sale or other disposition of the Notes 
made outside Brazil by a Non-Resident holder to another Non-Resident shouldnot 
be subject to Brazilian taxes. However, considering the general and unclear 
scope of this legislation and the absence of judicialguidance in respect 
thereof, we cannot assure prospective investors that such interpretation of 
this law will prevail in the courts ofBrazil. If the income tax is deemed to 
be due, the gains may be subject to income tax in Brazil, effective as from 
January 1, 2017,(as confirmed by Declaratory Act No. 3, of April 27, 2016), at 
progressive rates as follows: (i) 15% for the part of thegain that does not 
exceed R$5 million, (ii) 17.5% for the part of the gain that exceeds R$5 
million but does not exceed R$10 million,(iii) 20% for the part of the gain 
that exceeds R$10 million but does not exceed R$30 million and (iv) 22.5% for 
the part ofthe gain that exceeds R$30 million; or 25.0% if such Non-Resident 
holder is located in a Low or Nil Tax Jurisdiction as it will be furtherdetailed
 below. A lower rate, however, may apply under an applicable tax treaty 
between Brazil and the country where the Non-Residentholder has its domicile.



                                       S-                                       
                                       52                                       


Payments Made by Petrobras as Guarantor

In the event the issuer failsto timely pay any due amount, including any 
payment of principal, interest or any other amount that may be due and payable 
in respectof the Notes, the guarantor will be required to assume the 
obligation to pay such due amounts. As there is no specific legal 
provisiondealing with the imposition of withholding income tax on payments 
made by Brazilian sources to Non-Resident beneficiaries under guaranteesand no 
uniform decision from the Brazilian courts, there is a risk that tax 
authorities will take the position that the funds remittedby the guarantor to 
the Non-Resident holders may be subject to the imposition of withholding 
income tax at a general 15% rate, or ata 25% rate, if the Non-Resident holder 
is located in a Low or Nil Tax Jurisdiction. Arguments exist to sustain that 
(a) paymentsmade under the guarantee structure should be subject to imposition 
of withholding income tax according to the nature of the guaranteedpayment, in 
which case only interest and fees should be subject to taxation at a rate of 
15%, or 25%, in cases of beneficiaries locatedin Low or Nil Tax Jurisdictions, 
as defined by the Brazilian legislation; or (b) payments made under guarantee 
by Brazilian sourcesto Non-Resident beneficiaries should not be subject to the 
imposition of withholding income tax, to the extent that they should qualifyas 
a credit transaction by the Brazilian party to the borrower. As noted above, 
the imposition of withholding income tax under thesecircumstances has not been 
settled by the Brazilian courts.

If the payments with respectto the Notes are made by Petrobras as a guarantor, 
then Non-Resident holders will be indemnified so that, after payment of 
applicableBrazilian taxes imposed by deductions or withholding with respect to 
principal or interest payable with respect to the Notes, subjectto certain 
exceptions, as mentioned in "Description of the Notes-Covenants-Additional 
Amounts," a Non-Residentholder will receive an amount equal to the amount that 
such Non-Resident holder would have received if no such taxes were imposed. 
See"Description of the Notes-Covenants-Additional Amounts."

") introduced the concept of "privilegedtax regime" which concept is broader 
than the concept of a Favorable Tax Jurisdiction. A "
privileged tax regime
"is a regime that (1) does not tax income or taxes it at a maximum rate lower 
than 20% (or 17% if the country complies with internationaltax transparency 
standards; however, Law No. 14,596 (as defined below) changed this threshold 
from 20% to 17%, as a general matterfrom 2024 onwards, as discussed below); 
(2) grants tax advantages to a non-resident entity or individual (a) without 
the needto carry out a substantial economic activity in the country or in the 
territory, or (b) conditioned upon the non-exercise of a substantialeconomic 
activity in the country or in the territory; (3) does not tax or taxes foreign 
sourced income at a maximum rate lower than20% (or 17% if the country complies 
with international tax transparency standards; however, Law No. 14,596 (as 
defined below) changedthis threshold from 20% to 17%, as a general matter 
since January 2024, as discussed below); or (4) restricts the disclosureof 
information related to the ownership of shares, goods and rights, as well as 
to the information related to the economic transactionscarried out.

For the purpose of qualificationas a Favorable Tax Jurisdiction, a regulation 
issued by the Brazilian tax authorities on November 28, 2014 (Ordinance 488, 
of 2014)had already decreased from 20% to 17% the minimum threshold for 
certain specific cases. The 17% threshold applied only to countries andregimes 
aligned with international standards of fiscal transparency in accordance with 
rules established by the Brazilian tax authorities.

On December 29, 2022,the Brazilian government published the Provisional 
Measure No. 1,152, which was converted into Law No. 14,596 on June 15,2023 ("

Law No. 14,596/23
"). Specifically in relation to the concepts of Favorable Tax Jurisdictions 
and"privileged tax regimes", Law No. 14,596/23 established a minimum threshold 
tax rate of 17%, a change from the minimumrate of 20% mentioned above. As 
mentioned above, the 17% rate was already adopted as a minimum threshold for 
countries and regimes thatcomply with Normative Instruction No. 1,530, dated 
December 19, 2014 ("
Normative Instruction No. 1,530
").Under these rules, however, tax authorities could reinstate the 20% 
threshold at any time. Law No. 14,596/23 set in legal statutesthe minimum 17% 
threshold for all cases and regardless of compliance with Normative 
Instruction No. 1,530. This new threshold isin effect since January 2024, 
except in the case of the taxpayers that opted to anticipate the effects of 
said law (which were alreadysubject to the new threshold in 2023).


                                       S-                                       
                                       53                                       


On June 4, 2010, theBrazilian federal tax authorities enacted Normative 
Instruction No. 1,037, as amended ("
IN 1,037/10
"),listing (i) the countries and jurisdictions considered Favorable Tax 
Jurisdictions, and (ii) the privileged tax regimes. Thisis an exhaustive list 
and has not yet been updated to reflect changes from Law No. 14,596.

The interpretation of thecurrent tax legislation could lead to the conclusion 
that the concept of "Privileged Tax Regime" should apply solely forpurposes of 
Brazilian transfer pricing and thin capitalization rules, stricter 
deductibility rules and other specific situationsfor specific taxpayers (a 
binding tax ruling -
Solucao de Consulta COSIT
No. 575, dated as of December 20,2017 - issued by Brazilian tax authorities 
seems to confirm this interpretation). However, one cannot assure that 
subsequent legislationor interpretations issued by the Brazilian tax 
authorities regarding the definition of a "Privileged Tax Regime" providedby 
Law No. 11,727/08 and Law No. 14,596/23 will not also apply to payments to 
Non-Resident holders in connection with the notes.

In the event that the privilegedtax regime concept is interpreted to be 
applicable to transactions such as payments related to the Notes to 
Non-Resident, Law 11,727/08would accordingly result in the imposition of 
taxation to a Non-Resident that meets the privileged tax regime requirements 
in the sameway applicable to a resident located in a Favorable Tax 
Jurisdiction.

Holders should consult withtheir own tax advisors regarding the consequences 
of the implementation of Law 11,727/08, Law 14,596/23 and IN 1,037/10 and of 
any relatedBrazilian tax law or regulation concerning Favorable Tax 
Jurisdictions and "privileged tax regimes".

Other Tax Considerations

Brazilian law imposes a Taxon Foreign Exchange Transactions (
Imposto sobre Operacoes de Credito, Cambio e Seguro, ou relativas a Titulose 
Valores Mobiliarios),
or IOF/Exchange, due on the conversion of
reais
into foreign currency and on the conversionof foreign currency into
reais
. Currently, the IOF/Exchange rate for almost all foreign currency exchange 
transactions is 0.38%.According to Section 15-B of the Decree No. 6,306, as 
amended, the settlement of exchange transactions in connection with 
foreignfinancing or loans, for both inflow and outflow of proceeds into and 
from Brazil, are subject to IOF/Exchange at a 0% rate. Currently,in the case 
of the settlement of foreign exchange transactions (including simultaneous 
foreign exchange transactions), in connectionwith the inflow of proceeds to 
Brazil deriving from foreign loans, including those obtained through the 
issuance of notes in the internationalmarket, the IOF/Exchange tax rate is 0%. 
The Brazilian government is permitted to increase this rate at any time up to 
25.0%. Any suchincrease in rates may only apply to future transactions.

In addition, the Braziliantax authorities could argue that a Tax on Loan 
Transactions (Imposto sobre Operacoes de Credito, Cambio eSeguro, ou relativas 
a Titulos e Valores Mobiliarios), or IOF/Credit, due on loan transactions 
could be imposed upon anyamount paid in respect of the Notes by the guarantor 
under the guarantee given at a rate of up to 1.88% of the total amount paid. 
IOF/Credit,however, can only be levied on on-shore loan transactions, so 
cross-border payments to investors resident outside Brazil should not 
besubject to this taxation.

Generally, there are no inheritance,gift, succession, stamp, or other similar 
taxes in Brazil with respect to the ownership, transfer, assignment or other 
disposition ofthe Notes by a Non-Resident, except for gift and inheritance 
taxes imposed by some Brazilian states on gifts or bequests by individualsor 
entities not domiciled or residing in Brazil to individuals or entities 
domiciled or residing within such states.

Dutch Tax Considerations

The following describes certainmaterial Dutch tax consequences for a holder 
who is neither a resident nor deemed to be a resident of the Netherlands for 
Dutch tax purposesin respect of the ownership, acquisition and disposal of the 
Notes.


                                       S-                                       
                                       54                                       


This section is based onthe Dutch tax laws, published regulations thereunder 
and published authoritative case law, all as in effect on the date hereof, 
including,for the avoidance of doubt, the tax rates applicable on the date 
hereof, and all of which are subject to change or to different interpretation,po
ssibly with retroactive effect. Any such change may invalidate the contents of 
this section, which will not be updated to reflect suchchange. Where this 
section refers to "the Netherlands" and "Dutch" it refers only to the part of 
the Kingdomof the Netherlands located in Europe. In addition, this section is 
based on the assumption that the Notes issued by PGF do not qualifyas equity 
for Dutch tax purposes.

This section is intendedas general information only, it does not constitute 
tax or legal advice and it does not purport to describe all possible Dutch tax 
considerationsor consequences that may be relevant to a holder and does not 
purport to deal with the tax consequences applicable to all categoriesof 
investors, some of which may be subject to special rules. In view of its 
general nature, it should be treated with appropriate caution.

PROSPECTIVE INVESTORSSHOULD CONSULT THEIR OWN TAX ADVISERS AS TO THE 
CONSEQUENCES OF PURCHASING THE NOTES, INCLUDING, WITHOUT LIMITATION, THE 
CONSEQUENCESOF THE RECEIPT OF INTEREST AND THE SALE OR OTHER DISPOSITION OF 
THE NOTES OR COUPONS.

For Dutch tax purposes, aholder of Notes may include, without limitation:


 . an owner of one or more Notes who, in addition to the title to such Notes, has an economic interest in such Notes;



 . a person or an entity that holds the entire economic interest in one or more Notes;



 . a person or an entity that holds an interest in an entity, such as a partnership or a mutual fund,
   that is transparent for Dutch tax purposes, the assets of which comprise one or more Notes; and   



 . a person who or an entity that does not have the legal title to the Notes, but to whom the Notes are attributed based either on 
   such person or entity holding a beneficial interest in the Notes or based on specific statutory provisions, including statutory 
   provisions pursuant to which the Notes are attributed to a person who is, or who has directly or indirectly inherited the Notes 
   from a person who was, the settlor, grantor or similar originator of a trust, foundation or similar entity that holds the Notes.

   more of either the annual profit or

   deemed substantial interest may                                     
   arise if a substantial interest (or

Dutch Withholding Tax

Holders of Notes NotRelated to PGF

All payments made by PGFunder the Notes to holders of Notes other than holders 
that are "related entities" in respect of PGF (within the meaning ofthe Dutch 
Withholding Tax Act 2021;
Wet bronbelasting 2021
) (see below) can be made free of withholding or deduction for any taxesof any 
nature imposed, levied, withheld or assessed by the Netherlands or any 
political subdivision or taxing authority thereof or therein,unless the Notes 
qualify as equity of PGF for Dutch tax purposes.

Holders of Notes Relatedto PGF

Payments of interest (oramounts deemed interest) made by PGF under the Notes 
to holders of Notes that are related entities in respect of PGF (within the 
meaningof the Dutch Withholding Tax Act 2021, as defined below) may become 
subject to Dutch withholding tax at a rate of 25.8% (rate for 2024),if such 
related entity:

   on low-taxing states and non-cooperative jurisdictions for tax purposes (
   Regeling laagbelastende staten en niet-cooperatieve                      
   rechtsgebieden voor belastingdoeleinden

 . has a permanent establishment located in a Listed Jurisdiction to which the interest payment is attributable; or



 . is entitled to the interest payment with the main purpose or one of the main purposes of avoiding taxation for another person
   or entity and there is an artificial arrangement or transaction or a series of artificial arrangements or transactions; or   



 . is not considered to be the recipient of the interest in its jurisdiction of residence because  
   such jurisdiction treats another entity as the recipient of the interest (a hybrid mismatch); or



 . is not resident in any jurisdiction (also a hybrid mismatch); or



 . is a reverse hybrid (within

   ), if and to the extent (x) there is a participant in the reverse hybrid holding a Qualifying Interest in the      
   reverse hybrid, (y) the jurisdiction of residence of the participant holding the Qualifying Interest in the reverse
   hybrid treats the reverse hybrid as transparent for tax purposes and (z) such participant would have been subject  
   to Dutch withholding tax in respect of the payments of interest without the interposition of the reverse hybrid;   


all within the meaning ofthe Dutch Withholding Tax Act 2021.

Related entity

For purposes of the DutchWithholding Tax Act 2021, an entity is considered a 
"related entity" in respect of PGF if:


 . such entity has a Qualifying Interest (as defined below) in PGF; or



 . PGF has a Qualifying Interest in such entity; or



 . a third party has a Qualifying Interest in both PGF and such entity.


The term "QualifyingInterest" means a direct or indirectly held interest - 
either by an entity individually or jointly if an entity is part ofa 
collaborating group (
samenwerkende groep
) - that enables such entity or such collaborating group to exercise a 
definiteinfluence over another entity's decisions, such as PGF decisions, and 
allows it to determine the other entity's activities (within themeaning of 
case law of the European Court of Justice on the right of freedom of 
establishment (
vrijheid van vestiging
).

Dutch Gift and InheritanceTaxes

No Dutch gift or inheritancetaxes are due in respect of any gift of Notes by, 
or inheritance of the Notes on the death of a holder, except if:


 (i) at the time of the gift or death of the holder, the holder is                                     
     a resident, or is deemed to be a resident, of the Netherlands                                     
     or the transfer is otherwise construed as a gift or inheritance made by, or on behalf of, a person
     who, at the time of the gift or death, is or is deemed to be a resident of the Nether-lands;

statements of Petrobras as of June 30, 2024 and for the three-month and 
six-month periodsended June 30, 2024 and 2023, incorporated by reference 
herein, KPMG Auditores Independentes Ltda., independent registered

accordance with professional standards for a review of such information.However,
 their separate report included in the Petrobras
Form 6-K furnished to the SEC on August 9, 2024
and incorporated byreference herein, states that they did not audit and they 
do not express an opinion on those unaudited condensed consolidated 
interimfinancial statements. Accordingly, the degree of reliance on their 
report on such information should be restricted in light of the limitednature 
of the review procedures applied. The accountants are not subject to the 
liability provisions of Section 11 of the SecuritiesAct for their report on 
the unaudited condensed consolidated interim financial statements because that 
report is not a `report'or a `part' of the registration statement prepared or 
certified by the accountants within the meaning of Sections 7 and 11of the 
Securities Act.
