RETENTION PAYMENT AND SEPARATION BENEFITS ATTACHMENT

Payments of your separation pay under Paragraph b.1 shall be made monthly beginning the month after separation; provided, however, that to the extent required by Section 409A of the U.S. Internal Revenue Code and the regulations promulgated thereunder (“Section 409A”), the payment of certain amounts will be delayed until the seventh month that begins after your separation date. Payment under Paragraph b.2 will be made as soon as practicable after the date you become entitled to the payment under this provision or at the time provided for in any underlying compensation arrangement or plan if required for compliance with Section 409A. Although not guaranteed by the Company, payments under this attachment are intended to be exempt or compliant with Section 409A, and the attachment will be interpreted accordingly. Payments under this attachment will be subject to all applicable tax and tax-related items withholding requirements. In addition, the separation payments to be paid pursuant to this attachment will not exceed the amount permitted under Oxy's Golden Parachute Policy unless such separation payments are approved by a vote of Oxy's stockholders.
