• uncontracted areas (Federal Government, represented by PPSA) with 1.89%; and

• an area of the Argonauta Field (BC-10) with 0.86%;

The agreement establishes each party’s interest and the rules for the joint implementation of the development and production operations of oil and natural gas in the shared reservoir. The interests of each party in the Jubarte shared reservoir are as follows:

Interests in the Shared Reservoir
PETROBRAS	97.250%
SHELL	0.430%
BRAVA	0.198%

The AIP is executed when reservoirs extend beyond the boundaries of the contracted or concession areas, according to ANP regulations. Following ANP approval, the AIP will become effective on August 01, 2025.

As a result of the process of individualizing the production of the deposit, the companies' commitment includes the obligation to negotiate financial compensation between the expenses incurred and the revenues relating to the volumes produced up to the effective date of the AIP.
