 (1) Including Notes held by Petrobras or its affiliates.

     purchase. In addition, PGF will pay accrued and unpaid interest as set forth below.    


The Tender Offers will expire at 5:00 p.m., New York City time, onSeptember 9, 
2024, unless extended with respect to a Tender Offer (such date and time, as 
the same may be extended with respect to aTender Offer, the "
Expiration Date
"). Tender Notes validly tendered may be withdrawn at any time prior to 5:00 
p.m.,New York City time, on September 9, 2024, unless extended with respect to 
a Tender Offer, but not thereafter. The settlement date ofthe Tender Offers 
will occur promptly following the Expiration Date, expected to be no later 
than four business days following the ExpirationDate, which is expected to be 
September 13, 2024 (the "
Settlement Date
").




Holders of Tender Notes who (1) validly tender and do not validlywithdraw 
their Tender Notes on or prior to the Expiration Date or (2) deliver a 
properly completed and duly executed notice of guaranteeddelivery and other 
required documents pursuant to the guaranteed delivery procedures described in 
the Offer to Purchase on or prior tothe Expiration Date, and deliver their 
Tender Notes on or prior to 5:00 p.m., New York City time, on the second 
business day followingthe Expiration Date, which is expected to be September 
11, 2024 (the "
Guaranteed Delivery Date
"), will be eligibleto receive the applicable Consideration indicated in the 
table above, as well as accrued and unpaid interest from, and including, 
thelast interest payment date for the Tender Notes to, but not including, the 
Settlement Date (the "
Accrued Interest
").

The Tender Offers are not contingent upon the tender of any minimumprincipal 
amount of Tender Notes. The consummation of a Tender Offer is not conditioned 
on the consummation of the other Tender Offers.Each Tender Offer is 
independent of the other Tender Offers, and PGF may, subject to applicable 
law, withdraw or modify any Tender Offerwithout withdrawing or modifying other 
Tender Offers.

PGF will not be obligated to (i) accept for purchase any validly tenderedTender 
Notes or (ii) pay any cash amounts or complete the Tender Offers, unless 
certain conditions are satisfied or waived prior to theExpiration Date, 
including:


 - customary conditions such as that PGF will not be obligated to consummate the Tender
   Offers upon the occurrence of an event or events that would or might reasonably     
   be expected to prohibit, restrict or delay the consummation of the Tender Offers    
   or materially impair the contemplated benefits to PGF of the Tender Offers, and     



 - the entry by PGF prior to the Expiration Date into an underwriting agreement, on terms and    
   conditions reasonably satisfactory to PGF, for the New Notes Offering yielding net proceeds to
   PGF sufficient to fund, in addition to available cash, the Maximum Consideration (as defined  
   below) and Accrued Interest due to holders of Tender Notes tendered in the Tender Offers.     


PGF will not be obligated to (i) accept for purchase any validly tenderedTender 
Notes or (ii) pay any cash amounts or complete the Tender Offers, unless the 
New Notes Offering successfully closes and PGF receivesthe net proceeds 
therefrom on or prior to the Settlement Date.

PGF's obligation to accept for purchase, and to pay the applicableConsideration 
for a particular series of Tender Notes validly tendered pursuant to the 
Tender Offers is also subject to, and conditionedupon (the "
Maximum Consideration Condition
"), the aggregate Consideration for the Tender Offers, excluding the 
AccruedInterest with respect to each series (the "
Aggregate Consideration
"), not exceeding US$1.0 billion (the "
MaximumConsideration
").

If the Maximum Consideration Condition is not satisfied with respectto each 
series of Tender Notes for (i) a series of Tender Notes (the "
First Non-Covered Tender Notes
") for which theMaximum Consideration is less than the sum of (x) the 
Aggregate Consideration for all validly tendered First Non-Covered Tender 
Notesand (y) the Aggregate Consideration for all validly tendered Tender Notes 
of all series, having a higher Acceptance Priority Level (with1 being the 
highest Acceptance Priority Level and 6 being the lowest Acceptance Priority 
Level) than the First Non-Covered Tender Notes,and (ii) all series of Tender 
Notes with an Acceptance Priority Level lower than the First Non-Covered 
Tender Notes (together with theFirst Non-Covered Tender Notes, the "
Non-Covered Tender Notes
"), then PGF may, at any time at or prior to the ExpirationDate:


 (a) terminate a Tender Offer with respect to one or more series of Non-Covered Tender
     Notes for which the Maximum Consideration Condition has not been satisfied       
     and promptly return all validly tendered Tender Notes of such series, and of     
     any series of Non-Covered Tender Notes to the respective tendering holders; or   






 (b) waive the Maximum Consideration Condition with respect to one or more series of Non-Covered Tender Notes and accept all Tender
     Notes of such series, and of any series of Tender Notes having a higher Acceptance Priority Level, validly tendered; or       



 (c) if there is any series of Non-Covered Tender Notes for which:



 1. the Aggregate Consideration necessary to purchase all validly tendered Tender Notes of such series,
    plus                                                                                               



 2. the Aggregate Consideration necessary to purchase all validly tendered Tender Notes of all series having a 
    higher Acceptance Priority Level than such series of Tender Notes, other than any Non-Covered Tender Notes,


are equal to, or less than, the Maximum Consideration, acceptall validly 
tendered Tender Notes of all series having a lower Acceptance Priority Level, 
until there is no series of Tender Notes witha higher or lower Acceptance 
Priority Level to be considered for purchase for which the conditions set 
forth above are met.

It is possible that a series of Tender Notes with a particular AcceptancePriorit
y Level will fail to meet the conditions set forth above and therefore will 
not be accepted for purchase even if one or more serieswith a higher or lower 
Acceptance Priority Level are accepted for purchase. If any series of Tender 
Notes is accepted for purchase underthe Tender Offers, all Tender Notes of 
that series that are validly tendered will be accepted for purchase.

For purposes of determining whether the Maximum Consideration Conditionis 
satisfied, PGF will assume that all Tender Notes tendered pursuant to the 
guaranteed delivery procedures described in the Offer toPurchase will be duly 
delivered at or prior to the Guaranteed Delivery Date and it will not 
subsequently adjust the acceptance of theTender Notes in accordance with the 
Acceptance Priority Levels if any such Tender Notes are not so delivered.

PGF may, in its sole discretion, waive any one or more of the conditionsat any 
time, including the Maximum Consideration Condition with respect to any Tender 
Offer, even if the series of Tender Notes relatingto such an Tender Offer has 
a lower Acceptance Priority Level than other Non-Covered Tender Notes with a 
higher Acceptance Priority Level.

PGF expressly reserves the right, subject to applicable law, to: (i)delay 
accepting the Tender Notes or extend the Expiration Date or, if the conditions 
to the Tender Offers are not satisfied, terminatesuch Tender Offers at any 
time and not accept the Tender Notes; and (ii) if the conditions to the Tender 
Offers are not satisfied, amendor modify at any time, the terms of the Tender 
Offers in any respect, including by waiving, where possible, any conditions to 
consummationof the Tender Offers.

If PGF exercises any such right with respect to one or more seriesof Tender 
Notes, it will give written notice thereof to the Depositary (as defined 
below) and will make a public announcement thereofas promptly as practicable 
and all Tender Notes tendered pursuant to such terminated Tender Offer(s) and 
not accepted for payment willbe returned promptly to the tendering holders 
thereof. If the Maximum Consideration Condition is not satisfied with respect 
to a seriesof Tender Notes, elections to the guaranteed delivery procedures 
will be promptly rejected with respect to such series.

Petrobras believes that the operation is in line with thecompany's debt 
management policy, maintaining its commitment to controlling debt at what it 
considers to be a healthy levelfor companies of Petrobras' segment and size.
