DESCRIPTION OF THE NOTES</div>

The following description of the terms of the Notes supplements and modifies the description of the general terms and provisions of debt securities and the indenture set forth in the accompanying prospectus, which you should read in conjunction with this prospectus supplement. In addition, we urge you to read the indenture, including the seventh supplemental indenture in connection with the 2030 Notes, and the eighth supplemental indenture in connection with the 2036 Notes, because they will define your rights as holders of the 2030 Notes and the 2036 Notes, respectively. If the description of the terms of the Notes in this prospectus supplement differs in any way from that in the accompanying prospectus, you should rely on the information contained in this prospectus supplement. You may obtain copies of the indenture, including the seventh supplemental indenture and the eighth supplemental indenture, upon written request to the trustee or with the SEC at the addresses set forth under “Where You Can Find More Information.”

The Seventh Supplemental Indenture and the Eighth Supplemental Indenture.

PGF will issue the Notes under an indenture dated as of August 28,
2018 between PGF and The Bank of New York Mellon, a New York banking corporation, as trustee. This indenture will be supplemented by the
seventh supplemental indenture in the case of the 2030 Notes and the eighth supplemental indenture in the case of the 2036 Notes, each
dated as of the closing date, among PGF, Petrobras and The Bank of New York Mellon, as trustee, which provide the specific terms of the
Notes offered by this prospectus supplement, including granting holders rights against Petrobras under the guaranties.

Whenever we refer to the
“indenture” in this prospectus supplement, we are referring to the indenture dated as of August 28, 2018, as
supplemented by the seventh supplemental indenture in the case of the 2030 Notes and the eighth supplemental
