ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS

On January 11, 2003, Apache Corporation ("Apache") signed two purchase and sales
agreements with subsidiaries of BP p.l.c. (referred to collectively as "BP"), to
purchase their interests in 61 producing fields, including 113 blocks in the
Gulf of Mexico and two producing fields in the North Sea for $1.3 billion. Each
of the purchase agreements was effective as of January 1, 2003. Upon closing of
each transaction the purchase price was adjusted for normal closing and working
capital adjustments and, in the case of the Gulf of Mexico properties, the
exercise of preferential rights by third parties. Upon closing of the
acquisitions, Apache assumed BP's abandonment obligation for the properties and
such costs were considered in determining the purchase price.

Apache and BP closed on the Gulf of Mexico and North Sea properties on March 13,
2003 and April 2, 2003, respectively. Upon closing, Apache paid a purchase
price, adjusted for normal closing and working capital adjustments, of $509
million for the Gulf of Mexico properties and $630 million for the North Sea
assets. The Gulf of Mexico purchase price included a reduction of $70 million
for the exercise of preferential rights by third parties. Apache issued press
releases dated March 18, 2003 and April 2, 2003 announcing the two closings. The
press releases are listed under Item 7 as Exhibits 99.1 and 99.2 and are
incorporated herein by reference.

Apache estimates that the properties acquired from BP had proved reserves as
of January 1, 2003 of:

         o        183.9 MMbbls of crude oil and natural gas liquids; and

         o        237.6 Bcf of natural gas.

Apache has agreed to sell all of the North Sea production from those properties
over the next two years to BP at a combination of fixed and market sensitive
prices pursuant to a contract entered into in connection with the North Sea
purchase agreement.

The purchase price was paid in cash, which was funded from the proceeds of an
underwritten offering of Apache common stock, from the sale of Apache commercial
paper and borrowings under Apache's existing lines of credit. The offering of
Apache's common stock was underwritten by Morgan Stanley & Co. Incorporated,
Salomon Smith Barney Inc., RBC Dain Rauscher Inc., A.G. Edwards & Sons, Inc.,
Petrie Parkman & Co., Inc., Raymond James & Associates Inc., and Robert W. Bard
& Co. Incorporated, and provided net proceeds to Apache of approximately $553.4
million. The final prospectus supplement used in the offering is listed under
Item 7 as Exhibit 99.3 and is incorporated herein by reference.

Other than Apache's negotiations and discussions with representatives of BP
concerning the transactions described above, there are no material relationships
between BP and Apache or any of Apache's affiliates, officers or directors, or
any associate of any officer or director of Apache.
