The Exchange Offers were made pursuant to the terms and conditions set forth in Occidental’s prospectus, dated as of August 15, 2019 (the “Prospectus”), as amended by a press release issued by Occidental on August 29, 2019, and the related Letter of Transmittal and Consent (the “Letter of Transmittal”). The Prospectus forms a part of the Registration Statement on Form S-4, which was filed with the Securities and Exchange Commission (“SEC”) on August 1, 2019, as amended by Amendment No. 1 thereto filed with the SEC on August 13, 2019 (the “Registration Statement”), and declared effective on August 15, 2019.

Following the Expiration Date, tenders of Old Notes may not be validly withdrawn. As of the Expiration Date, all conditions to the Exchange Offers were satisfied, other than (a) the conditions that Occidental obtains (i) the requisite consents applicable to each series of Old Notes to adopt the Proposed Amendments for all series of Old Notes at or by the Expiration Date (the “Requisite Consents”) and (ii) the valid tender (without valid withdrawal) of a majority in aggregate principal amount of the Old Notes of all series at or by the Expiration Date, each of which Occidental waived as announced on August 29, 2019, and (b) the condition that Occidental obtains the receipt of the Requisite Consents for the 7.250% Debentures due 2025 issued by Anadarko and the 7.250% Debentures due 2096 issued by Anadarko (together, the “Specified Old Notes”). Occidental currently anticipates that the settlement date of the Exchange Offers will be September 18, 2019. Eligible holders of Old Notes other than the Specified Old Notes who validly tendered and did not validly withdraw such notes at or prior to the Expiration Date are eligible to receive the total consideration set forth in the table above. Occidental will not accept any Specified Old Notes tendered for exchange in the Exchange Offers.

With respect to the Old Notes other than the Specified Old Notes, at 5:00 p.m., New York City time, on August 28, 2019, Occidental had obtained the Requisite Consents. Accordingly, supplemental indentures to the applicable Old Notes Indentures that implement the Proposed Amendments were executed by Anadarko, Anadarko HoldCo, Anadarko Finance and Kerr-McGee on August 29, 2019. Such supplemental indentures will become operative upon the settlement of the Exchange Offers.

This press release is not an offer to sell or a solicitation of an offer to buy any of the securities described herein and is also not a solicitation of the related consents. The Exchange Offers were made solely pursuant to the terms and conditions of the Prospectus, the Letter of Transmittal and the other related materials. The Exchange Offers were not made in any state or jurisdiction in which such offers would have been unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.
