In addition, several Corporate functions will continue to report to him. Dr. Irani also informed the Board of his intention to retire at the end of 2014.

Dr. Irani said, “Steve is a proven leader who has been an integral member of the senior management team for many years, and I am confident that he will continue to make significant contributions to Occidental’s ongoing success and development.”

Aziz D. Syriani, Lead Independent Director of Occidental’s Board, said on behalf of the Board of Directors, “Dr. Irani has been an outstanding CEO who has brought great vision to the Company, and the Board is extremely pleased that Occidental shareholders will continue to benefit from his strengths in his new role.
