ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS
- ------  ------------------------------------

     As previously reported, on March 7, 2000, Occidental Petroleum Corporation
("Occidental") entered into an agreement to acquire all of the common
partnership interest in Altura Energy Ltd. ("Altura"), the largest oil producer
in the state of Texas. Altura has proved reserves of approximately 850 million
barrels of oil equivalent, which are located in the Permian Basin.

     The transaction, valued at approximately $3.6 billion, closed on April 19,
2000. Occidental, through its subsidiaries, paid approximately $1.2 billion to
the sellers, affiliates of BP Amoco plc and Shell Oil Company, to acquire the
common limited partnership interest and control of the general partner which
manages, operates and controls 100 percent of the Altura assets. The partnership
borrowed approximately $2.4 billion, which has recourse only to the Altura
assets. The partnership also loaned approximately $2.0 billion to affiliates of
the sellers, evidenced by two notes, which provide credit support to the
partnership. The sellers retained a preferred limited partnership interest of
approximately $2.0 billion and are entitled to certain distributions from the
partnership. An affiliate of BP Amoco plc also retained a non-controlling
interest in the general partner that manages Altura.

     As a result of the acquisition, Occidental's worldwide oil production for
2000 will rise to 480,000 barrels of oil equivalent per day, a 13 percent
increase above the average for 1999. In addition, Occidental's worldwide proved
reserves are expected to increase to approximately 2.2 billion barrels, on an
oil-equivalent basis.

ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS
- ------- ---------------------------------

     (a)  Financial statements of business acquired.

          Altura Energy Ltd. Audited Financial Statements for the years ended
     December 31, 1999 and 1998 and for the period from March 1, 1997 to
     December 31, 1997 together with the report of Ernst & Young LLP thereon
     (the "Altura Financial Statements") (attached as Exhibit 99.1 hereto).

     (b)  Pro forma financial information.

     The following unaudited pro forma financial information has been prepared
in accordance with the rules and regulations of the Securities and Exchange
Commission. This transaction has been reflected as if it had occurred for
financial position purposes on December 31, 1999 and for results of operations
purposes on January 1, 1999. These pro forma financial statements do not reflect
anticipated cost savings, synergies, changes in realized prices or production
rates or certain other adjustments that may result from the acquisition of the
Altura interest. The historical financial information for Occidental has been
derived from Occidental's audited financial statements for the year ended
December 31, 1999, incorporated by reference in Occidental's Annual Report on
Form 10-K for the year ended December 31, 1999 (the "Form 10-K"). The historical
financial information for Altura has been derived from the audited Altura
historical financial statements included in this filing. The unaudited pro forma
financial information should be read in conjunction with Occidental's historical
financial statements incorporated by reference in the Form 10-K, and the Altura
historical financial statements. The pro forma information is not necessarily
indicative of the results or the financial position that would have been
obtained had the transaction actually occurred on the dates specified above. In
addition, such pro forma information does not purport to project Occidental's
results of operations or financial position as of any future date or for any
future period.

     A preliminary allocation of the purchase price has been made to major
categories of assets and liabilities in the accompanying pro forma financial
statements based on available information. The actual allocation of the purchase
price and the resulting effect on income from operations may differ from the pro
forma amounts included herein. These pro forma adjustments represent
Occidental's preliminary determination of purchase accounting adjustments and
are based upon available information and certain assumptions that the Company
believes to be reasonable. Consequently, the amounts reflected in the pro forma
financial statements are subject to change.
