GLOSSARY OF TERMS

Branded Jobber/Dealer Stations - Retail stations owned by third parties that
sell products purchased from or through the Company and carry one of the
Company's brands (Tesoro, Tesoro Alaska or Amoco).

Clean Fuels Capital - Capital expenditures required to meet Clean Air Act
regulations related to reductions in emissions and new manufacturing standards
required to reduce the sulfur content in gasoline starting January 1, 2004 and
highway diesel fuels starting June 1, 2006.

Company-Owned Stations - Retail stations owned by the Company.

Discretionary Capital - Capital expenditures undertaken primarily for increased
economic return on investment.

EBITDA - Earnings before interest and financing costs, income taxes and
depreciation and amortization. The Company uses EBITDA as a measure for internal
analysis and in presentations to analysts, investors and lenders. The
calculation of EBITDA is not based on accounting principles generally accepted
in the United States ("U.S. GAAP") and should not be considered as an
alternative to net earnings or cash flows from operating activities (which are
determined in accordance with U.S. GAAP), as an indicator of operating
performance or as a measure of liquidity. EBITDA may not be comparable to
similarly titled measures used by other entities. EBITDA has been restated from
the Company's other public documents to exclude interest income from EBITDA.

Gross Refining Margin - Margin on products manufactured and purchased, including
those sold to the Company's Retail System. Sales to the Retail System have been
based on average bulk market prices adjusted for transportation and other
differentials.

Heavy Oils, Residual Products & Other - Product yields other than gasoline, jet
fuel and diesel produced in the refining process. These include products such as
residual fuels, gas oils, propane, and internally-produced fuel.

Manufacturing Costs - Costs associated directly with the manufacturing process
including cash operating expenses and non-cash amortization of maintenance
turnaround costs, but excluding depreciation. Manufacturing costs also include
costs of internally-produced fuel.

Mbpd - Thousand barrels per day.

Net Refining Margin - Gross Refining Margin minus Manufacturing Costs.

Non-Discretionary Capital - Capital expenditures required for continuing
operations.



                                                                               2

NOTES:

Scheduled maintenance turnarounds were as follows:

     *Alaska in 2Q 1999 and 2Q 2001

     *Washington in 4Q 1999

Next turnarounds are scheduled as follows:

     *Washington in 1Q 2002 and 3Q 2003

     *Alaska in 2Q 2003

The distillate treater at the Company's Washington refinery was placed in
service during December 1999.

The Company commenced a heavy oil conversion project at its Washington refinery
in 2000, which will enable the Company to manufacture a larger proportion of
higher-value gasoline and to reduce production of lower-value heavy products.
The Company expects to spend approximately $109 million (including capitalized
interest) for this project, of which $97 million had been spent through December
31, 2001. The first stage of the project, the installation of a de-asphalting
unit, was completed in late September 2001. Management expects the upgrade of
the fluid catalytic cracking unit, the final major component of the heavy oil
conversion project, to be operational in March 2002.

NOTES:

(a) Volumes for 2001 include amounts for North Dakota and Utah operations since
their acquisition on September 6, 2001 averaged over the periods presented (28.7
Mbpd in throughput and 29.5 Mbpd in yield in 3Q01; 104.8 Mbpd in throughput and
108.7 Mbpd in yield in 4Q01; 33.7 Mbpd in throughput and 34.8 Mbpd in yield for
the year 2001). For the first 25 days of operations in 3Q01, refinery throughput
and yield averaged 105.8 Mbpd and 108.7 Mbpd, respectively. For the 117 days in
operations during the year 2001, refinery throughput and yield averaged 105.0
Mbpd and 108.7 Mbpd, respectively.

The classification of crude oil between heavy crude and light crude has been
revised for Mid-Continent refineries resulting in heavy crude throughput
percentages for the total refinery system in 2001 to 42% for 3Q, 40% for 4Q and
45% for the year.

(b) Excludes depreciation, but includes non-cash amortization of major
maintenance costs. Also includes costs of internally-produced fuel.

MID-CONTINENT REFINERIES - HISTORICAL

On September 6, 2001, Tesoro acquired two refineries in North Dakota and Utah
and related storage, distribution and retail assets from certain affiliates of
BP p.l.c. The acquisitions increased the Company's number of refineries from
three to five, with aggregate refining capacity rising from 275,000 barrels per
day ("bpd") to 390,000 bpd, and increased the Company's retail gas station
network from approximately 300 stations to 650 stations. In addition, on
November 1, 2001, the Company acquired a crude oil gathering and transmission
system located in Montana and North Dakota, which provides crude oil to the
North Dakota refinery.

NOTES:

(a) The historical data above represents information prior to Tesoro's
acquisition of these assets from BP. Results from these acquired assets are
included in Tesoro's consolidated financials since the date of acquisition, or
September 6, 2001. Results from the crude gathering and pipeline system are
included in Tesoro's results from the date of acquisition on November 1, 2001.

Gross refining margins per barrel for this region were approximately $5.23 for
the year 1999, $6.36 for the year 2000, and $8.28 for the first half of 2001.
Margins were derived from historical BP financial statements and were not
calculated in the same manner as Tesoro's other refineries.

(b) The unaudited pro forma information gives effect to the acquisitions of the
BP assets (including the crude gathering and pipeline system) and the effect of
the Company's recent financings and notes offering, as if these transactions had
occurred on January 1, 2000. The unaudited pro forma information is not
necessarily indicative of the results that actually would have been achieved had
these transactions been consummated on January 1, 2000, or that may be achieved
in the future.

                                                            Prepared on 11/26/01

CLEAN FUELS AND CLEAN AIR CAPITAL

Exhibit 10 contains the Company's preliminary estimates of its capital
requirements to meet new Clean Fuels and Clean Air standards. Actual
expenditures, and the timing of these expenditures, will likely differ from
these estimates due to a number of factors, including, among others, the final
selections of technology, equipment design changes, regional variations in
requirements, implementation of other refinery improvements, and other factors
which are beyond the Company's control (see Forward-Looking Statements
disclaimer at www.tesoropetroleum.com/forwardlooking.html).
