                 Tesoro Reports Second Quarter Results


    SAN ANTONIO--(BUSINESS WIRE)--xx--Tesoro Petroleum Corporation
(NYSE:TSO) today reported net income before special items of $14.0
million, or $0.22 per share, for the second quarter of 2003, excluding
an after-tax charge of $21.0 million, or $0.33 per share, to write off
the unamortized debt issuance costs of the company's previous credit
facility. Including the write off, the company reported a net loss
during the quarter of $7.0 million, or $0.11 per share, compared to a
net loss of $17.9 million, or $0.28 per share, for the second quarter
of 2002.
    For the first half of 2003, the company reported net income before
special items of $40.1 million, or $0.62 per share, excluding
after-tax charges of $26.7 million, or $0.41 per share, for the
write off of the unamortized debt issuance costs of the company's
previous credit facility along with charges primarily related to the
company's early retirement and severance program costs. Including
these charges, the company reported year-to-date net income of $13.4
million, or $0.21 per share, compared to a net loss of $73.5 million,
or $1.30 per share, for the first six months of 2002.
    "Operationally, we are pleased with the results this quarter,
given that industry refining margins were below first quarter and
mid-cycle levels," said Bruce A. Smith, Chairman, President and CEO of
Tesoro. "Although margins were better than the second quarter of 2002,
industry refining margins for our operating areas averaged $9.48 per
barrel, down $0.79 per barrel from the first quarter's average of
$10.27 per barrel and below the five-year average for the second
quarter of $10.30 per barrel. The challenges during the quarter
included a crude oil market that was highly volatile and a narrowing
discount on heavy crude oil causing downward pressure on our refining
margin, compared to the margin we experienced during the first
quarter."
    Operating income for the refining segment during the second
quarter was $72.3 million compared to $109.2 million during the first
quarter of 2003. Total refinery throughput averaged 497,200 barrels
per day (bpd) during the second quarter compared to 464,500 bpd during
the first quarter of 2003. "Although our overall throughput seasonally
increased compared to the first quarter, total throughput was
negatively impacted by a turnaround at our Alaska refinery, reduced
throughput rates due to unplanned maintenance at our Golden Eagle
plant, and reduced rates at our Hawaii refinery due to reduced jet
fuel demand," stated Smith.
    Retail operations increased operating income during the quarter to
$10.3 million compared to the first quarter operating loss of $8.1
million. "Our retail segment reported a strong improvement compared to
the first quarter as marketing margins across the country showed
marked improvement. During the quarter, retail also benefited from a
lower cost structure," commented Smith.
    "During the quarter we repaid $171 million of debt. As of June 30,
we had $129 million remaining on our $500 million goal. Debt reduction
remains our top financial priority and with reasonable margins, we
expect to continue to generate strong cash flow and reduce our debt,"
added 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) During the three months ended June 30, 2003 the Company wrote-off
    approximately $33.3 million 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 three months and six months ended June
    30, 2002 the Company recorded charges of $3.5 million and $12.6
    million, respectively, for financing costs related to the
    acquisition of the California refinery.

(c) The assumed conversion of common stock equivalents produced anti-
    dilutive results for the three months ended June 30, 2003 and the
    three months and six months ended June 30, 2002 and therefore was
    not included in the dilutive calculations.

(e) 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. Gross refining margin per barrel may
    not be comparable to similarly titled measures used by other
    entities.

(f) 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
    entities.

(g) Gross refining margin is revenues less cost of refining feedstock.
    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.

(h) Includes $2.6 million for voluntary early retirement benefits and
    severance payments during the six months ended June 30, 2003.

(i) Includes manufacturing depreciation and amortization per
    throughput barrel of approximately $0.58 and $0.56 for the three
    months ended June 30, 2003 and 2002, respectively, and $0.60 and
    $0.56 for the six months ended June 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.

(l) In December 2002, the Company sold 70 company-operated stations
    that were acquired with the California refinery.

(m) Fuel margin per gallon is calculated by dividing fuel gross margin
    by fuel sales volumes. Fuel margin per gallon may not be
    comparable to similarly titled measures used by other entities.
    Management uses fuel margin per gallon calculations to compare
    profitability to other companies in the industry.

(n) Includes the effect of intersegment purchases from the Refining
