     STATEMENT UNDER OATH OF PRINCIPAL EXECUTIVE OFFICER REGARDING FACTS AND

I, Ray R. Irani, state and attest that:

(1) To the best of my knowledge, based upon a review of the covered reports of
Occidental Petroleum Corporation, and, except as corrected or supplemented in a
subsequent covered report:

     o no covered report contained an untrue statement of a material fact as of

     Form 8-K or definitive proxy materials, as of the date on which it was
     filed); and

     o no covered report omitted to state a material fact necessary to make the
     statements in the covered report, in light of the circumstances under which
     they were made, not misleading as of the end of the period covered by such
     report (or in the case of a report on Form 8-K or definitive proxy
     materials, as of the date on which it was filed).

(2) I have reviewed the contents of this statement with Occidental's Audit
Committee.

(3) In this statement under oath, each of the following, if filed on or before
the date of this statement, is a "covered report":

     o Annual Report on Form 10-K for the fiscal year ended December 31, 2001 of
     Occidental Petroleum Corporation;

     o all reports on Form 10-Q, all reports on Form 8-K and all definitive
