                     Tesoro Reports Third Quarter Earnings

    SAN ANTONIO--(BUSINESS WIRE)--xx--Tesoro Petroleum Corporation
(NYSE:TSO) today reported net earnings of $70.6 million, or $1.09 per
share, for the third quarter of 2003 versus a net loss of $15.8
million, or $0.24 per share, for the third quarter of 2002. Results
for the third quarter include after-tax charges of $4.7 million, or
$0.07 per share, for the loss on the pending sale of the Marine
Service assets and $1.8 million, or $0.03 per share for the
accelerated amortization of debt issuance costs due to the company
prepaying $125 million of debt during the quarter. Excluding these
special items, net earnings for the quarter were $77.1 million, or
$1.19 per share, compared to a net loss excluding special items for
the third quarter of 2002 of $18.8 million, or $0.29 per share.
    For the first nine months of 2003, Tesoro reported net earnings of
$84 million, or $1.30 per share, versus a net loss for the first nine
months of 2002 of $89.3 million, or $1.51 per share. Results for the
first nine months of 2003 include after-tax charges of $33.2 million,
or $0.51 per share, for the write-off of the unamortized debt issuance
costs related to the company's previous credit facility and other debt
prepayments, charges for the company's early retirement and severance
program costs in the first quarter of 2003, along with the loss on the
pending sale of the Marine Service assets. Excluding special items,
net earnings were $117.2 million, or $1.81 per share, compared to a
net loss before special items of $81.9 million, or $1.38 per share,
for the first nine months of 2002.
    "The reliability of our operations enabled us to benefit from the
seasonally strong gasoline demand and higher margin environment due to
industry supply problems on the West Coast," said Bruce A. Smith,
Chairman, President and CEO of Tesoro. "We did not, however, see the
full benefit of the improved margin environment in the mid-continent
region since our Mandan refinery had a planned maintenance turnaround
for almost the entire month of September."
    As previously announced, the company prepaid the remaining balance
of its current asset term loan of approximately $125 million during
the quarter. "Although we have made significant strides this year in
reducing our overall debt, continued debt reduction remains our top
financial priority," stated Smith.

Note: Results include the California refinery operations acquired in
May 2002 and interest expense for the related financing.

(a) Certain reclassifications were made to prior period amounts to
    conform to current presentation, principally to reclassify
    amortization of major maintenance turnaround costs from operating
    expenses to depreciation and amortization and to net purchases and
    sales considered to be energy trading contracts.
(b) On October 27, 2003, the Company agreed to sell substantially all
    of the physical assets of Marine Services for approximately $32
    million including inventories, which are estimated to be valued at
    $5 million. The Company recorded a pretax estimated loss of $7.6
    million, or $0.07 per share, in September 2003, reflecting the
    sales value of the assets and estimated selling costs.
(c) The Company wrote-off approximately $2.9 million and $36.2 million
    during the three months and nine months ended September 30, 2003,
    respectively, of unamortized debt issue costs related to voluntary
    prepayments of debt and the replacement of the Company's previous
    credit facility with a new credit agreement and term debt during
    the 2003 second quarter. The Company also recorded charges of
    $12.6 million during the nine months ended September 30, 2002 for
    financing costs related to the acquisition of the California
    refinery.
(d) The assumed conversion of common stock equivalents produced
    anti-dilutive results for the three months and nine months ended
    September 30, 2002 and therefore was not included in the dilutive
    calculations.

(f) Management uses gross refining margin per barrel to compare
    profitability to other companies in the industry. Gross refining
    margin per barrel is calculated by dividing gross refining margin
    by total refining throughput and may not be calculated similarly
    by other companies.
(g) Management uses manufacturing costs per barrel to evaluate the
    efficiency of refinery operations. Manufacturing costs per barrel
    may not be comparable to similarly titled measures used by other
    companies.
(h) Gross refining margin is revenues less cost of refining feedstock,
    which approximates total Refining segment throughput times gross
    refining margin per barrel, adjusted for changes in refined
    product inventory due to selling a volume and mix of product that
    is different than actual volumes manufactured. Also includes the
    effect of intersegment sales to the Retail segment at prices which
    approximate market. In addition, during the three months ended
    September 30, 2002, certain inventory quantities were reduced,
    resulting in the liquidation of applicable LIFO inventory
    quantities carried at lower costs. This reduction in LIFO
    inventory resulted in a decrease in cost of sales of approximately
    $5 million and a decrease in net loss of $3 million for the three
    months and nine months ended September 30, 2002.
(i) Includes manufacturing depreciation and amortization per
    throughput barrel of approximately $0.55 and $0.51 for the three
    months ended September 30, 2003 and 2002, respectively, and $0.58
    and $0.54 for the nine months ended September 30, 2003 and 2002,
    respectively.
(j) Sources of total product sales include products manufactured at
    the refineries, products drawn from inventory balances and
    products purchased from third parties. Total product sales margin
    included margins on sales of manufactured and purchased products
    and the effects of inventory changes.
