ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS

         On May 17, 2002, Tesoro Petroleum Corporation ("Tesoro" or the
"Company") completed the acquisition of the 168,000 barrel-per-day Golden Eagle
refinery located in Martinez, California in the San Francisco Bay area along
with 70 associated retail sites throughout northern California (collectively,
the "Golden Eagle Assets") from Ultramar Inc., a subsidiary of Valero Energy
Corporation. The acquisition was completed pursuant to a Sale and Purchase
Agreement, dated February 4, 2002, by and among Ultramar Inc. and Tesoro
Refining and Marketing Company, as amended on February 20, 2002 and May 3, 2002,
incorporated herein by reference as Exhibit 2.1 to this Current Report on Form
8-K. The Company intends to utilize the Golden Eagle Assets in a similar manner
as the seller.

         The purchase price for the Golden Eagle Assets, as amended, was $945
million, plus $130 million for feedstock and refined product inventories,
subject to post-closing adjustments. The Company issued to the seller two
ten-year junior subordinated notes with face amounts aggregating $150 million as
part of the $945 million purchase price. The notes consist of: (i) a $100
million junior subordinated note, due July 2012, which will be non-interest
bearing for the first five years and carry a 7.5% interest rate for the
remaining five-year period, and (ii) a $50 million junior subordinated note, due
July 2012, which will have no interest payment in year one, will include a 7.47%
effective interest rate for the second through the fifth years, and will bear
interest at 7.5% for years six through ten. Copies of The $100 million and $50
million junior subordinated notes are filed as Exhibits 10.1 and 10.2 to this
Current Report on Form 8-K and are incorporated herein by reference. The Company
further funded the acquisition of the Golden Eagle Assets with borrowings under
its amended and restated Senior Secured Credit Facility (see Item 5), proceeds
of a recent common stock offering and the proceeds of a recent senior
subordinated notes offering. The Company also assumed certain liabilities and
obligations (including costs associated with transferred employees and
environmental matters, among others) subject to certain levels of
indemnification.

         In connection with the acquisition of the Golden Eagle Assets, the
Company entered into a letter agreement, dated May 5, 2002, with the State of
California Department of Justice, Office of the Attorney General, which is filed
as Exhibit 10.3 to this Current Report on Form 8-K and is incorporated herein by
reference.

         The foregoing is qualified by reference to Exhibits 2.1, 10.1, 10.2 and
10.3 to this Current Report on Form 8-K, which are incorporated herein by
reference.

ITEM 5. OTHER EVENTS

         On May 17, 2002, the Company amended and restated its Senior Secured
Credit Facility to increase the facility to $1.275 billion consisting of (i) a
$225 million revolving credit facility (with a $150 million sublimit for letters
of credit) which will terminate on September 6, 2006, (ii) a $250 million
tranche A term loan which terminates on December 31, 2006 and (iii) a $800
million tranche B term loan which terminates on December 31, 2007. The Company
entered into this amended and restated Senior Secured Credit Facility with
Lehman Brothers Inc. as arranger, Lehman Commercial Paper Inc. as syndication
agent, Bank One, NA as administrative agent, ABN Amro Bank N.V., Credit Lyonnais
New York Branch and The Bank of Nova Scotia, as co-documentation agents, and a
syndicate of banks, financial institutions and other entities. The amended
facility includes a minimum Consolidated EBITDA (as defined in the amended and
restated Senior Secured Credit Facility) covenant of $40 million applicable only
to the second quarter of 2002, eliminates the total debt to EBITDA test and
substitutes a new senior debt to EBITDA test beginning in the third quarter of
2002. The amended facility also includes interest and fixed charge coverage
tests beginning in the third quarter of 2002. These coverage tests are similar
to the original facility except that the new facility provides that for purposes
of determining compliance with the tests, EBITDA attributable to the Golden
Eagle Assets shall be based on the results of operations after the acquisition
thereof. The incremental proceeds from the term loans were used to partially
fund the acquisition of the Golden Eagle Assets. A copy of the amended and
restated Senior Secured Credit Facility is filed as Exhibit 10.4 to this Current
Report on Form 8-K and is incorporated herein by reference.
