I previously received a copy of the Offer to Exercise Warrants to Purchase Common Stock, dated March 3, 2025, and any amendments or supplements thereto (the “Offer to Exercise”) of Occidental Petroleum Corporation (the “Company”) and properly elected to participate in the Offer to Exercise.

I hereby irrevocably withdraw my previously submitted election to participate in the Offer to Exercise and reject the Offer to Exercise.

I understand that by rejecting the Offer to Exercise, my Warrants, each exercisable for one share of the Company’s common stock, par value $0.20 per share (“Common Stock”), will not be exercised pursuant to the terms of the Offer to Exercise and will remain in full force and effect as originally issued with an exercise price of $22.00 per Warrant. I waive any right to receive any notice of the acceptance of this Notice of Withdrawal. All capitalized terms used but not defined herein shall have the meanings ascribed to the Offer to Exercise.

No Notice of Withdrawal will be deemed to be properly made until all defects and irregularities have been cured or waived. Unless waived, any defects or irregularities in connection any Notice of Withdrawal must be cured within such time as the Company shall determine. Neither the Company nor any other person is or will be obligated to give notice of any defects or irregularities in any Notice of Withdrawal and none of them will incur any liability for failure to give any such notice.
