                              GENERAL INFORMATION

     This Proxy Statement is furnished in connection with the solicitation by
the Board of Directors (sometimes referred to herein as the "Board") of Tesoro
Petroleum Corporation ("Tesoro" or the "Company") of proxies to be voted at the
2000 Annual Meeting of Stockholders to be held on Thursday, May 25, 2000, and at
any adjournment thereof.

     Each proxy will be voted as specified thereon by the stockholder. Any duly
executed proxy not specifying the contrary will be voted (i) for the directors
nominated for election at the meeting, (ii) in favor of the proposal to increase
the number of shares which can be granted under the Amended and Restated
Executive Long-Term Incentive Plan, and (iii) for the ratification of the
appointment of Deloitte & Touche LLP as the Company's independent auditors for
fiscal year 2000. A stockholder giving a proxy may revoke it by written notice
to the Secretary of the Company at any time before it is voted.

     At the close of business on April 5, 2000, the record date for the 2000
annual meeting, there were outstanding and entitled to vote 31,718,115 shares of
Common Stock of the Company. The holders of Common Stock are entitled to one
vote for each share held by them on all matters submitted to them. The Company
has no other voting securities outstanding.

     A copy of the Company's Summary Annual Report for fiscal year 1999 has
previously been mailed to all stockholders as of the record date. The Company's
complete Consolidated Financial Statements, Selected Financial Data,
Management's Discussion and Analysis of Financial Condition and Results of
Operations, and Quantitative and Qualitative Disclosures About Market Risk,
taken from the Company's Annual Report on Form 10-K for the fiscal year ended
December 31, 1999 are included in Appendix A to this document. Such Summary
Annual Report and Appendix A hereto do not constitute a part of the proxy
materials.

     The principal executive offices of the Company are located at 300 Concord
Plaza Drive, San Antonio, Texas 78216-6999. This Proxy Statement and
accompanying form of proxy are being mailed to stockholders on or about April
25, 2000.

                            1. ELECTION OF DIRECTORS

     At the 2000 annual meeting, the stockholders are requested to elect seven
directors, constituting the whole Board of Directors, to hold office until the
2001 Annual Meeting of Stockholders or until their successors are elected and
qualified. Proxies cannot be voted for more than seven nominees. Unless
otherwise specified, all duly executed proxies received on a timely basis will
be voted for the nominees set forth below. Each of such nominees has indicated
his willingness to serve as a director, if elected, and the Company has no
reason to believe that any nominee will be unable to serve. The persons
designated as proxies, however, reserve full discretion to cast votes for other
persons in the event that any one or more of the nominees are unable to serve.

     The election of director nominees requires a plurality of the votes cast at
the election. Under Delaware law and the Company's Restated Certificate of
Incorporation and By-laws, shares as to which a stockholder withholds authority
to vote on the election of directors ("Abstentions"), and shares as to which a
broker indicates that it does not have discretionary authority to vote ("Broker
Non-Votes") on the election of directors, will not be counted as voting thereon
and will not affect the election of the nominees receiving a plurality of the
votes cast.

INFORMATION CONCERNING DIRECTORS AND NOMINEES

     Certain information as to each nominee for director is set forth in the
table below and in the following paragraphs. Certain of the information
appearing in the table and notes thereto has been furnished to the Company by
the respective nominees.

Directors, as appropriate, efforts to assure the Company's compliance with the
requirements of the Foreign Corrupt Practices Act of 1977, as amended. The Audit
Committee met four times during fiscal year 1999.

     The Compensation Committee's primary purposes are (i) to review and approve
all areas of senior executive compensation including but not limited to salary
adjustments, cash incentive awards and stock incentives, and to review and
approve the aggregate amount of all merit increases, cash incentive awards and
stock incentives for the Company's other executives; (ii) to administer and
interpret the Company's Amended Incentive Stock Plan of 1982 (the "1982 Plan"),
Amended and Restated Executive Long-Term Incentive Plan (the "1993 Plan") and
any future incentive plans, to the extent set forth in such plans; (iii) to
review Company retirement matters, consider amendments to the Company's
retirement plans based on cost and benefit considerations, make recommendations
to the Board of Directors in respect to such amendments and proposals, and
review and approve any overall changes in retirement benefit formulas; (iv) to
review new employment agreements, amendments and extensions of existing
employment agreements, and to make recommendations to the Board of Directors
with respect to such agreements; (v) to administer and interpret employment
agreements and make recommendations to the Board of Directors with respect
thereto; and (vi) to consult with the Board of Directors and review with the
Board the actions of the Compensation Committee as appropriate. The Compensation
Committee met eight times during fiscal year 1999.

     The Governance Committee considers and recommends to the Board from time to
time suitable candidates for membership on the Board, including nominees
recommended by stockholders. Stockholders wishing to submit a recommendation
should write to the Governance Committee. Stockholders may also make nominations
for director at annual or certain special stockholder meetings if they comply
with the procedures described below. The Governance Committee also reviews and
makes recommendations to the Board annually regarding (i) the organization and
structure of the Board and the committees of the Board and selection of new
director candidates; (ii) compensation for the members of the Board; (iii)
guidelines on corporate governance issues; and (iv) the role and effectiveness
of the Chief Executive Officer, the Board and each committee of the Board. The
Governance Committee met two times during fiscal year 1999.

     Under the Company's By-laws, a stockholder of the Company entitled to vote
for the election of directors, may, if he or she complies with the following
procedures, make a nomination for director at a stockholder meeting. Nominations
for director may be made by stockholders only after compliance with the
procedures set forth in the Company's By-laws. The following summary is
qualified in its entirety by reference to the full text of the By-laws. Written
notice of such stockholder's intent to make such nomination must be delivered to
the Company (Attention: Corporate Secretary) on a timely basis as set forth
below and must contain (i) the name and address of the stockholder as it appears
on the Company's books and of the beneficial owner, if any, on behalf of whom
such nomination is made, and (ii) as to each person whom the stockholder
proposes to nominate for election as a director, all information relating to
such person that is required to be disclosed in solicitation of proxies for
election of directors, or is otherwise required by Regulation 14A under the
Securities Exchange Act of 1934, as amended ("Exchange Act"), including such
person's written consent to being named in the proxy statement as a nominee and
to serving as a director if elected.

     In the case of an annual meeting of stockholders, the required notice must
be delivered not less than 60 days nor more than 90 days prior to the first
anniversary of the preceding year's annual meeting; provided that, in the event
that the date of the annual meeting is advanced by more than 30 days or delayed
by more than 60 days from such anniversary date, the notice must be delivered no
earlier than the ninetieth day prior to such annual meeting and not later than
the close of business on the later of the sixtieth day prior to such annual
meeting or the tenth day following the day on which public announcement of the
date of such meeting is first made. If the number of directors to be elected to
the Board is increased and there is no public announcement specifying the size
of the increased Board made by the Company at least 70 days prior to the first
anniversary of the preceding year's annual meeting, a notice will be considered
timely, but only with respect to nominees for any new positions created by such
increase, if delivered not later than the close of business on the tenth day
following the day on which the public announcement is first made by the Company.
In the case of a special meeting of stockholders at which directors are proposed
to be elected in the notice of meeting, the stockholder wishing to make a
nomination for director must deliver the required written notice to
                                        4
<PAGE>   7

the Company (Attention: Corporate Secretary) not earlier than the ninetieth day
prior to the special meeting and not later than the close of business on the
later of the sixtieth day prior to such meeting or the tenth day following the
day on which public announcement is first made of the date of the special
meeting and of the nominees proposed by the Board to be elected at such meeting.
                             ---------------------

COMPENSATION OF DIRECTORS

     Each member of the Board of Directors who is not an officer of the Company
receives (i) a base retainer of $18,000 per year, (ii) an additional $2,000 for
each meeting of the Board of Directors or any committee thereof attended in
person, including committee meetings held on the same day as a meeting of the
Board of Directors, and (iii) $1,000 for each telephone meeting in which the
member participates. The non-executive Vice Chairman of the Board of Directors
receives $25,000 per year for his service. In addition, the Chairman of the
Audit Committee, Chairman of the Compensation Committee and Chairman of the
Governance Committee each receive $5,000 per year for their service in such
positions. The Company provides group life insurance benefits in the amount of
$100,000 and accidental death and dismemberment insurance up to a maximum of
$350,000 for each of the members of the Board of Directors who are not employees
of the Company. The premium for such insurance ranged from $259 to $3,810 for
each of these directors during fiscal year 1999.

     One-half of each of the director's annual retainer is paid in Common Stock
of the Company on an annual basis. Within 30 days after the annual meeting of
stockholders of the Company at which the director is elected, the Company issues
a number of shares equal to one-half of the annual retainer in effect on the
date of such meeting divided by the average of the closing prices for the Common
Stock, as reported on the New York Stock Exchange ("NYSE") composite tape, for
the ten trading days prior to such annual meeting. The shares of Common Stock
issued to the directors will be held by the Company and will not be sold,
pledged or otherwise disposed of and the shares will not be delivered to the
directors until the earliest of (i) the first anniversary date of the annual
meeting which immediately preceded the issuance of such shares or (ii) the next
succeeding annual meeting of the stockholders or (iii) the date on which the
person ceases to be a director; provided that, in the case of clause (iii), if
the person ceases to be a director for any reason other than death or
disability, the number of shares delivered shall be reduced pro rata for the
period of time from termination as a director to the first anniversary date of
the immediately preceding annual meeting of the stockholders. The directors will
have full voting rights with respect to such shares of Common Stock.

     Beginning in March 2000, one-half of the director fees paid for acting as a
committee chairman and for attendance at committee meetings of the Board of
Directors will also be paid in Common Stock of the Company by issuing to each
director a number of shares equal to one-half of the annual fee for acting as a
committee chairman or one-half of the fees for attendance at committee meetings
divided by the average closing prices of the Common Stock, as reported on the
NYSE composite transaction tape, for the ten days prior to such election, in the
case of election to the chairmanship of such committee, or the ten days prior to
determination of the annual aggregate fees for attendance at committee meetings,
in the case of attendance at such meetings. Upon issuance of shares of Common
Stock in payment for part of a director's committee chairmanship or attendance
at committee meetings, such shares will be deemed to be issued for services
rendered to the Company at least equal to such share's par value and will be
considered fully paid and nonassessable.

     The Company had previously established an unfunded Non-Employee Director
Retirement Plan ("Director Retirement Plan") which provided eligible directors
with retirement payments upon meeting certain age or other requirements.
However, to more closely align director compensation with shareholders'
interest, in March 1997, the Board of Directors elected to freeze the Director
Retirement Plan and transfer accrued benefits of each participating director to
an account ("Account") for each director in the Tesoro Petroleum Corporation
Board of Directors Deferred Phantom Stock Plan ("Phantom Stock Plan"). After the
amendment and transfer, only those retired directors or beneficiaries who had
begun receiving benefits remained participants in the Director Retirement Plan.
By participating in the Phantom Stock Plan, each director waives any and all
rights under the Director Retirement Plan. Under the Phantom Stock Plan, each

current and future non-employee director ("Participant") shall have credited to
his Account as of the last day of the year a yearly accrual equal to $7,250
(limited to 15 accruals, including previous accruals of retirement benefits
under the Director Retirement Plan); and each Participant who is serving as a
chairman of a committee of the Board of Directors immediately prior to his
termination as director and who has served at least three years as a director
shall have an additional $5,000 credited to his Account. The Phantom Stock Plan
allows for pro rata calculations of the yearly accrual in the event a director
serves for part of a year. In addition, a Participant may elect to defer any
part or all of the cash portion of his annual director retainer into his
Account. Each transfer, accrual or deferral shall be credited quarterly to the
Participant's Account in units based upon the number of shares that could have
been purchased with the dollars credited based upon the closing price of the
Company's Common Stock on the NYSE on the date the amount is credited. Dividends
or other distributions accrue to the Participant's Account. Participants are
vested 100 percent at all times with respect to deferrals and, if applicable,
the chairman fee portion of his Account. Participants vest in amounts
transferred from the Director Retirement Plan and the yearly accruals upon
completion of three full years of service as a member of the Board. If a
Participant voluntarily resigns or is removed from the Board prior to serving
three years on the Board, he shall forfeit all amounts not vested. If a director
dies, retires, or becomes disabled, he shall be 100 percent vested in his
Account without regard to services. Distributions from the Phantom Stock Plan
shall be made in cash, based on the closing market price of the Company's Common
Stock on the NYSE on the business day immediately preceding the date on which
the cash distribution is to be made, and such distributions shall be made in
either a lump-sum distribution or in annual installments not exceeding ten
years. Death, disability, retirement or cessation of a Participant as a director
of the Company constitute an event requiring a distribution. Upon the death of a
Participant, the Participant's beneficiary will receive as soon as practicable
the cash value of the Participant's Account as of the date of death. At December
31, 1999, Participant's Accounts included 5,778 units, 2,394 units, 16,040
units, 401 units, 2,836 units and 8,060 units of phantom stock for Messrs.
Grapstein, Johnson, Mason, Schmude, Ward and Weidenbaum, respectively.

     Under the Tesoro Petroleum Corporation Board of Directors Deferred
Compensation Plan ("Deferred Compensation Plan"), a director electing to
participate may defer between 20 percent and 100 percent of his total cash
compensation for the ensuing year, which deferred fees are credited to an
interest-bearing account maintained by the Company. Interest is applied to each
quarter's deferral at the prime rate published in The Wall Street Journal on the
last business day of such quarter plus two percentage points (10.5 percent at
December 31, 1999). All payments under the Deferred Compensation Plan are the
sole obligation of the Company. Upon the death of a participating director, the
balance in his account under the Deferred Compensation Plan is paid to his
beneficiary or beneficiaries in one lump sum. In the event of the disability,
retirement or the removal or resignation prior to the death, disability or
retirement of a participating director, the balance in his account will be paid
to such director in ten equal annual installments. In the event of a change of
control (as "change of control" is defined in the Deferred Compensation Plan),
the balance in each participating director's account will be distributed to him
as a lump sum within 30 days after the date of the change of control. The
Company also has an agreement with Frost National Bank of San Antonio, Texas,
under which the Tesoro Petroleum Corporation Board of Directors Deferred
Compensation Trust was established for the sole purpose of creating a fund to
provide for the payment of deferred compensation to participating directors
under the Deferred Compensation Plan.

     The Company's 1995 Non-Employee Director Stock Option Plan ("1995 Plan")
provides for the grant to non-employee directors of automatic, non-discretionary
stock options, at an exercise price equal to the fair market value of the Common
Stock as of the date of grant. Under the 1995 Plan, each person serving as a
non-employee director on February 23, 1995, or elected thereafter, initially
receives an option to purchase 5,000 shares of the Company's Common Stock.
Thereafter, each non-employee director, while the 1995 Plan is in effect and
shares are available to grant, is granted an option to purchase shares of Common
Stock (amounting to 1,000 shares prior to March 2000 and 3,000 shares
thereafter) on the next day after each annual meeting of the Company's
stockholders but not later than June 1, if no annual meeting is held. All
options under the 1995 Plan become exercisable six months after the date of
grant. The 1995 Plan will terminate as to the issuance of stock options in
February 2005. Under the 1995 Plan, stock options for 5,000 shares with an
exercise price of $18.625 per share were granted to Mr. Schmude upon his
election to the
                                        6

Board on September 15, 1999. In addition, stock options for 1,000 shares with an
exercise price of $18.4375 per share were granted to each non-employee director
of the Company on September 16, 1999. At April 5, 2000, the Company had 65,000
options outstanding and 62,000 shares available for future grants under the 1995
Plan.

STOCK OWNERSHIP

     The following table shows the beneficial ownership of the Company's Common
Stock reported to the Company as of April 5, 2000, including shares as to which
a right to acquire ownership exists (for example, through the exercise of stock
options or stock awards or conversion of Premium Income Equity Securities
("PIES")) within the meaning of Rule 13d-3(d)(1) under the Exchange Act for each
director and nominee, the Chief Executive Officer, the other four most highly
compensated officers of the Company during 1999 and, as a group, such persons
and other executive officers. Unless otherwise indicated, each person or member
of the group listed has sole voting and investment power with respect to the
shares of Common Stock listed. The PIES, which represent fractional interests in
the Company's 7.25% Mandatorily Convertible Preferred Stock, have no voting
rights. Before July 1, 2001, each PIES is convertible, at the option of the
holder thereof, into 0.8455 shares of Common Stock.

     accordingly, the only entities whose indirect beneficial ownership on an
     aggregate basis exceed 5 percent. In Amendment No. 2, each Reporting Person
     shows that they have shared voting and dispositive power and may be deemed

(a)  No payments were made to the named executive officers which are reportable
     in Other Annual Compensation. The aggregate amount of perquisites and other
     personal benefits was less than either $50,000 or 10 percent of the total
     annual salary and bonus reported for the named executive officers for all
     periods shown.

(b)  In October 1998, the Company's Board of Directors unanimously approved the
     1998 Performance Plan, which is intended to advance the best interests of
     the Company and its stockholders by directly targeting Company performance
     to align with the ninetieth percentile historical stock-price growth rate
     for the Company's peer group. In addition, the 1998 Performance Plan will
     provide the Company's employees with additional compensation, contingent
     upon achievement of the targeted objectives, thereby encouraging them to
     continue in the employ of the Company. The 1998 Performance Plan's targeted
     objectives are for the fair market value of the Company's Common Stock to
     equal or exceed an average of $35 per share (the "First Performance
     Target") and $45 per share (the "Second Performance Target") on any 20
     consecutive trading days during a period commencing on October 1, 1998 and
     ending on the earlier of September 30, 2002, or the date on which the
     Second Performance Target is achieved ("Performance Period"). Under the
     1998 Performance Plan, in 1998 Mr. Smith, Mr. Van Kleef and Mr. Reed
     received contingent awards of performance-vested phantom stock in the
     amount of 340,000, 190,000 and 125,000 shares, respectively, and Mr.
     Wormington and Mr. Reardon were awarded contingent cash bonus
     opportunities. The contingent awards of performance-vested phantom stock
     entitle the executive officers to receive cash in an amount equal to the
     number of shares of phantom stock granted to him, multiplied

                                       10
<PAGE>   13

     by the fair market value of a share of Common Stock on the last day of the
     Performance Period if the Second Performance Target is achieved. If the
     First Performance Target is attained but the Second Performance Target is
     not attained, the executive officer would receive 25 percent of the award.
     Payout is deferred until the end of the Performance Period if the First
     Performance Target is attained or 30 days after the Performance Period if
     the Second Performance Target is attained.

(c)  Amounts represent traditional stock options granted to each named executive
     officer during 1999, 1998 and 1997, except for grants to Mr. Smith in 1997
     which were in the form of phantom stock options. At the discretion of the
     Compensation Committee of the Board of Directors, the 175,000 phantom stock
     options granted to Mr. Smith in 1997 may be converted to traditional stock
     options under the 1993 Plan.

(d)  In 1996, the Compensation Committee of the Board of Directors approved a
     special incentive strategy comprised of long-term performance-vested
     restricted stock and stock options for the executive officers. Awards of
     restricted Common Stock and stock options under this strategy were earned
     when the market price of the Company's Common Stock reached an average
     price of $20 or higher over any 20 consecutive trading days after June 30,
     1997, and before December 31, 1998 (the "Performance Target"). In
     connection with this strategy, Messrs. Smith, Van Kleef and Reed were
     awarded 200,000, 75,000 and 75,000 shares, respectively, of restricted
     Common Stock, and Messrs. Wormington and Reardon were granted 75,000 and
     50,000 stock options, respectively, at an exercise price of $11.375 per
     share (the fair market value as defined in the 1993 Plan of a share of the
     Company's Common Stock on the date of grant). On May 12, 1998, the
     Performance Target was achieved which resulted in the lapse of restrictions
     on the restricted Common Stock and vesting of the stock options. Long-term
     incentive plan ("LTIP") payouts presented above represent the shares of
     Common Stock awarded under the incentive compensation strategy times
     $20.4375 per share, or the average market price of the Company's Common
     Stock on the day of reaching the Performance Target. Although Mr.
     Wormington and Mr. Reardon became fully vested in the stock options granted
     under this strategy upon reaching the Performance Target, none of the stock
     options have been exercised.

(e)  All Other Compensation for 1999 includes amounts contributed by the Company
     and earnings on the respective executive officer's account in a
     supplemental retirement plan, the Funded Executive Security Plan (see
     "Retirement Benefits" on page 17) of $1,517,927, $707,527, $953,356 and
     $551,837 for Mr. Smith, Mr. Van Kleef, Mr. Reed and Mr. Reardon,
     respectively; and amounts contributed to the Company's Thrift Plan of
     $8,292 for Mr. Smith and $9,600 for each of the other four named executive
     officers. All Other Compensation for 1998 includes amounts contributed by
     the Company and earnings on the respective executive officer's account in
     the Funded Executive Security Plan of $1,353,060, $460,500, $871,459, and
     $428,978 for Mr. Smith, Mr. Van Kleef, Mr. Reed and Mr. Reardon,
     respectively; and amounts contributed to the Company's Thrift Plan of
     $6,400 for each of the named executive officers. All Other Compensation for
     1997 includes amounts contributed by the Company and earnings on the
     respective executive officer's account in the Funded Executive Security
     Plan of $1,135,617, $362,941, $907,963 and $467,970 for Mr. Smith, Mr. Van
     Kleef, Mr. Reed and Mr. Reardon, respectively; and amounts contributed to
     the Company's Thrift Plan of $6,400 for each of the named executive
     officers.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     The Compensation Committee of the Board of Directors of Tesoro Petroleum
Corporation has prepared the following report regarding 1999 executive
compensation. The Compensation Committee, which is composed entirely of
non-employee directors, is responsible for the review, interpretation and
administration of all components of the Company's senior executive compensation
programs and the review and approval of the aggregate cost-related aspects of
other executive compensation. The Compensation Committee works closely with the
entire Board of Directors in the execution of its duties. This report is
required by rules established by the Securities and Exchange Commission and
provides specific information regarding compensation for the Company's Chairman,
President and Chief Executive Officer and for other officers named in the
Summary Compensation Table, as well as general compensation information of all
executive officers of the Company.

   COMPENSATION PHILOSOPHY AND OBJECTIVES OF EXECUTIVE COMPENSATION PROGRAMS

     It is the philosophy of the Company and the Compensation Committee that all
compensation programs should (i) link pay and performance and (ii) attract,
motivate, reward and retain the executive talent required to achieve corporate
objectives. The Company also focuses strongly on compensation tied to stock
price performance, since this form of compensation provides the clearest link
between senior executive rewards and enhanced shareholder value. Several times a
year, the Compensation Committee works with a nationally recognized compensation
consulting firm which assists the Compensation Committee with the design,
implementation and communication of various compensation plans.

     The Company determines competitive levels of compensation using published
compensation surveys (for energy and general industry companies of comparable
size to the Company as measured by revenues), information obtained from its
compensation consulting firm, and an analysis of compensation data contained in
the proxy statements for the energy industry peer companies included in the
Company's Total Shareholder Return Graph (the "Performance Graph").

     The Company's compensation programs for executives include base salaries,
annual performance-based incentives, long-term incentives and certain executive
benefits. Each of these compensation programs is further detailed below.

             DESCRIPTION OF THE 1999 EXECUTIVE COMPENSATION PROGRAM

  Base Salaries

     Base salaries for the Company's senior executive officers in 1999 were
reviewed through comparisons with the market survey data described above. The
Compensation Committee does not consider any financial performance criteria on a
formula basis in determining salary increases. Rather, the Compensation
Committee, using its discretion, considers market base salary rates at the
fiftieth percentile of energy and general industry companies of comparable size
to the Company (as measured by revenues), average annual salary increases for
executives in companies of various sizes across the country, and overall
corporate financial performance. The Compensation Committee also makes a
subjective review of individual performance in making decisions on base salaries
for senior executives. These criteria are assessed in a non-formula fashion and
are not weighted. The current base salary level for each of the named executive
officers is, overall, consistent with the Company's philosophy of targeting the
fiftieth percentile of the published compensation survey data previously
described.

  Annual Performance-Based Incentives

     Under the Company's 1999 annual incentive strategy, senior executive award
targets were set to bring total annual compensation to the fiftieth percentile
of the market survey data upon achievement of target performance. The strategy
was based on corporate performance for corporate positions (and for business
unit positions, a combination of corporate and business unit performance).
                                       13
<PAGE>   16

     Award allocations under the strategy for corporate positions were tied to
specific, quantitative performance measures as well as a qualitative assessment
of individual performance. The corporate financial objectives for 1999 were
Earnings per Share (weighted 70 percent) and Return on Capital Employed
(weighted 30 percent) relative to the Company's business plan. For business unit
positions, the quantitative performance measures included the overall corporate
financial objectives as well as specific operating profit measures for the
respective unit, division, downstream business, or a combination of these
groups. Certain other performance measures were also considered in determining
awards for business unit positions. These additional measures included safety
and environmental results, the achievement of synergies among the refining
groups, growth in customer base, and individual performance.

     Annual incentive awards earned in 1999 for corporate officers were paid
between target and maximum levels based on the Company's results and individual
performance. Payouts for business unit officers also generally fell between
target and maximum levels based on combined corporate and business unit results.

  Long-Term Incentives

     The Company believes that its executive officers should have an ongoing
stake in the success of the Company. The Company also believes that these key
employees should have a considerable portion of their total compensation tied to
the Company's stock price performance since stock-related compensation is
directly tied to shareholder value.

     In 1999, the Compensation Committee provided stock option grants to key
executives and to selected other employees under its ongoing long-term incentive
program. Stock options provide a strong tie between pay and performance, since
recipients realize value from stock options only if the Company's share price
rises above the grant price. All stock options in 1999 were granted at 100
percent of fair market value at the time of grant.

     In determining the size of stock option grants for executive officers in
1999, the Compensation Committee considered market data on typical stock option
grants at the market twenty-fifth, fiftieth and seventy-fifth percentiles. The
1999 stock option grants made to executives generally fell at the fiftieth
percentile based on the Chief Executive Officer's and Compensation Committee's
assessment of the individual's ability to affect long-term results. The
Compensation Committee also considered the Company's total compensation program
award opportunities in determining the size of these grants.

     In addition to its ongoing stock option program, the Company has
established a special long-term incentive plan, the 1998 Performance Incentive
Compensation Plan (the "1998 Performance Plan"), which is intended to provide
market ninetieth percentile total pay if the Company achieves outstanding share
price growth. The 1998 Performance Plan is also intended to encourage continued
employment with the Company. The 1998 Performance Plan provides awards in the
form of phantom stock for the Company's top three executive officers (including
the Chief Executive Officer) and cash bonus opportunities to other eligible
employees if specified stock price targets are achieved. The 1998 Performance
Plan's targeted objectives are for the fair market value of the Company's Common
Stock to equal or exceed an average of $35 per share (the "First Performance
Target") and $45 per share (the "Second Performance Target") on any 20
consecutive trading days during a period commencing on October 1, 1998, and
ending on the earlier of September 30, 2002, or the date on which the Second
Performance Target is achieved (the "Performance Period"). Upon achievement of
the First Performance Target, 25 percent of the awards would be vested, with
payout deferred until the end of the Performance Period. The remaining 75
percent would be vested only upon achievement of the Second Performance Target
during the Performance Period.

  Other Executive Benefits and Perquisites

     The Company also provides certain benefits and perquisites to its key
executive officers. These benefits and perquisites are not tied to any formal
performance criteria and are intended to serve as part of a competitive total
compensation package. These benefits and perquisites include, but are not
limited to, supplemental retirement plans, change-in-control arrangements, and,
for three of the senior executive officers, a flexible perquisites program (with
a dollar limit placed on perquisite expenses) and employment agreements.

Levels of Company benefits and perquisites for executives were in line with
market fiftieth to seventy-fifth percentile levels.

        DISCUSSION OF 1999 COMPENSATION FOR THE CHIEF EXECUTIVE OFFICER

     The discussion below applies to Mr. Smith's 1999 compensation.

  Base Salary

     Mr. Smith's annual base salary was increased from $700,000 to $770,000 in
1999. This base salary adjustment placed Mr. Smith's base salary at a level
consistent with the fiftieth percentile of the Company's comparison group in the
published compensation surveys previously described. The base salary adjustment
was intended to keep Mr. Smith's base pay at a competitive level and reflected
the Compensation Committee's assessment that Mr. Smith's performance continues
to be very strong.

  Annual Incentive Award

     Based on the Company's performance on the measures described under the
Annual Performance-Based Incentives section above (as well as strong individual
performance in developing and implementing the Company's strategy, in taking
steps to enhance shareholder value, and in pursuing targeted acquisitions), the
Compensation Committee awarded Mr. Smith an annual incentive of $850,000 for
1999. This award was between the targeted and maximum levels provided under the
program.

  Stock Options

     Mr. Smith received a grant of 300,000 stock options in 1999. These stock
options were granted at 100 percent of the fair market value of the Company's
Common Stock on the grant date. The size of the stock option grant was
established at the fiftieth percentile of the published compensation survey
data. Stock options are a performance-based element of compensation in that
options produce income for the recipient only if the Company's stock price rises
after the grant date.

             LIMITATION OF TAX DEDUCTION FOR EXECUTIVE COMPENSATION

     Section 162(m) of the Internal Revenue Code limits the tax deductibility by
a publicly held corporation of compensation in excess of $1 million paid to the
Chief Executive Officer or any other of its four most highly compensated
executive officers, unless that compensation is "performance-based compensation"
as defined by the Internal Revenue Code. The Company believes that its stock
option grants qualify as performance-based compensation and are not subject to
any deductibility limitations under Section 162(m). The Compensation Committee
considers deductibility under Section 162(m) with respect to other compensation
arrangements with executive officers. However, the Compensation Committee and
the Board believe that it is in the best interest of the Company that the
Compensation Committee retain its flexibility and discretion to make
compensation awards, whether or not deductible, in order to foster achievement
of performance goals established by the Compensation Committee as well as other
corporate goals that the Compensation Committee deems important to the Company's
success, such as encouraging employee retention and rewarding achievement.

PERFORMANCE GRAPH

     The Stock Price Performance Graph below compares the cumulative total
return of the Company's Common Stock to the cumulative total return of the S&P
500 Composite Index and to a composite peer group of companies. The composite
peer group (the "Peer Group") includes the following: Holly Corporation; Murphy
Oil Corporation; Ocean Energy, Inc.; Tosco Corporation; Ultramar Diamond
Shamrock Corporation; and Valero Energy Corporation. The Peer Group also
included the following companies (which have been merged or acquired) through
their last publicly-traded dates: The Louisiana Land and Exploration Company;
MAPCO Inc.; Oryx Energy Company; Quaker State Corporation; and Union Texas
Petroleum Holdings, Inc.. Due to the sale of the Company's exploration and
production operations in 1999, the Company is reevaluating its peer group
selection for 2000 to focus on its primary business segment, refining and
marketing. The line graph below is for the period of five fiscal years
commencing December 31, 1994 and ending December 31, 1999.

RETIREMENT BENEFITS

     The Company maintains a noncontributory qualified Retirement Plan which
covers officers and other eligible employees. Benefits under the plan are
payable on a straight life annuity basis and are based on the average monthly
earnings and years of service of participating employees. Average monthly
earnings used in calculating retirement benefits are primarily salary and bonus
received by the participating employee during the 36 consecutive months of the
last 120 months of service which produces the highest average monthly rate of
earnings.

     In addition, the Company maintains an unfunded executive security plan, the
Amended Executive Security Plan ("Amended Plan"), for executive officers and
other key personnel selected by the Chief Executive Officer. The Amended Plan
provides for a monthly retirement income payment during retirement equal to a
percentage of a participant's Earnings. "Earnings" is defined under the Amended
Plan to mean a participant's average monthly rate of total compensation,
primarily salary and bonus earned, including performance bonuses and incentive
compensation paid after December 1, 1993, in the form of stock awards of the
Company's Common Stock (excluding stock awards under the special incentive
compensation strategy and contingent awards under the 1998 Performance Plan),
for the 36 consecutive calendar months within the last ten-year period which
produce the highest average monthly rate of compensation for the participant.
The monthly retirement benefit percentage is defined as the sum of 4 percent of
Earnings for each of the first ten years of employment, plus 2 percent of
Earnings for each of the next ten years of employment, plus 1 percent of
Earnings for each of the next ten years of employment. The maximum percentage is
70 percent. The Amended Plan provides for the payment of the difference, if any,
between (a) the total retirement income payment calculated above and (b) the sum
of retirement income payments from the Company's Retirement Plan and Social
Security benefits.

     The Company also maintains the Funded Executive Security Plan ("Funded
Plan") which covers only selected persons approved by the Chief Executive
Officer, who are also participants in the Amended Plan, and provides
participants with substantially the same aftertax benefits as the Amended Plan.
Advance payments are made to the extent a participant is expected to incur a
pre-retirement tax liability as a result of his participation in the Funded
Plan. The Funded Plan is funded separately for each participant on an
actuarially determined basis through a bank trust whose primary asset is an
insurance contract providing for a guaranteed rate of return for certain
periods. Amounts payable to participants from the Funded Plan reduce amounts
otherwise payable under the Amended Plan.

     The following table shows the estimated annual benefits payable upon
retirement under the Company's Retirement Plan, Amended Plan and the Funded Plan
for employees in specified compensation and years of benefit service
classifications without reference to any amount payable upon retirement under
the Social Security law or any amount advanced before retirement. The estimated
annual benefits shown are based upon the assumption that the plans continue in
effect and that the participant receives payment for life. As of January 1,
2000, the federal tax law generally limits maximum annual retirement benefits
payable by the Retirement Plan to any employee to $135,000, adjusted annually to
reflect increases in the cost of living. However, since the Amended Plan and the
Funded Plan are not qualified under Section 401 of the Internal

                                       17
<PAGE>   20

Revenue Code of 1986, as amended (the "Code"), it is possible for certain
retirees to receive annual benefits in excess of this tax limitation.

     The years of benefit service as of December 31, 1999, for the named
executive officers were as follows: Mr. Smith, 7 years; Mr. Van Kleef, 6 years;
Mr. Reed, 25 years; Mr. Wormington, 4 years; and Mr. Reardon, 19 years.

     In addition to the retirement benefits described above, the Amended Plan
provides for a pre-retirement death benefit payable over eight years of four
times a participant's annual base pay as of December 1 preceding a participant's
date of death, less the amount payable from the Funded Plan at the date of
death. The amount payable from the Funded Plan at death is based on the
actuarial value of the participant's vested accrued benefit, payable in 96
monthly installments or as a life annuity if a surviving spouse is the
designated beneficiary.

EMPLOYMENT CONTRACTS, MANAGEMENT STABILITY AGREEMENTS AND CHANGE-IN-CONTROL
ARRANGEMENTS

     Under an amendment effective October 28, 1998 to an employment agreement
dated November 1, 1997, Mr. Smith is employed until November 1, 2000, at an
annual base salary of $770,000. Under separate employment agreements, Mr. Van
Kleef and Mr. Reed are employed until October 28, 2000, at annual base salaries
of $470,000 and $400,000, respectively. In addition to their base salaries, each
of the employment agreements for the above executives provides that the Company
shall establish an annual incentive compensation strategy for executive officers
in which each executive shall be entitled to participate in a manner consistent
with his position with the Company and the evaluations of his performance by the
Board of Directors or any appropriate committee thereof. The target incentive
bonus under the 1999 annual incentive compensation strategy was a percentage of
the respective executive officer's annual base salary and was 75 percent for Mr.
Smith, 65 percent for Mr. Van Kleef and 50 percent for Mr. Reed. Each of the
employment agreements also provides that the executive will receive an annual
amount ("flexible perquisite amount") to cover various business-related expenses
such as dues for country, luncheon or social clubs; automobile expenses; and
financial and tax planning expenses. The executive may elect at any time by
written notice to the Company to receive in cash any of such flexible perquisite
amount which has not been paid to or on behalf of the executive. The annual
flexible perquisite amount is $30,000, $20,000 and $20,000 for Mr. Smith, Mr.
Van Kleef and Mr. Reed, respectively. Each employment agreement also provides
that the Company will pay initiation fees for social clubs and reimburse the
executive for related tax expenses to the extent the Board of Directors, or a
duly authorized committee thereof, determines such fees are reasonable and in
the best interest of the Company.
                                       18
<PAGE>   21

     Each of the employment agreements with Mr. Smith, Mr. Van Kleef and Mr.
Reed provides that in the event the Company should terminate such executive
officer's employment without cause, if he should resign his employment for "good
reason" (as "good reason" is defined in the employment agreements), or if the
Company shall not have offered to such executive officer prior to the
termination date of his employment agreement the opportunity to enter into a new
employment agreement, with terms, in all respects, no less favorable to the
executive than the terms of his current employment agreement, such executive
will be paid a lump-sum payment equal to (i) three times (in the case of Mr.
Smith) and two times (in the case of Messrs. Van Kleef and Reed) the sum of (a)
his base salary at the then current rate and (b) the sum of the target bonuses
under all of the Company's incentive bonus plans applicable to such executive
for the year in which the termination occurs and (ii) if termination occurs in
the fourth quarter of a calendar year, the sum of the target bonuses under all
of the Company's incentive bonus plans applicable to such executive for the year
in which the termination occurs prorated daily based on the number of days from
the beginning of the calendar year in which the termination occurs to and
including the date of termination. Each executive shall also receive all unpaid
bonuses for the year prior to the year in which the termination occurs and shall
receive (i) for a period of two years continuing coverage and benefits
comparable to all life, health and disability insurance plans which the Company
from time to time makes available to its management executives and their
families, (ii) a lump-sum payment equal to two times the flexible perquisites
amount, and (iii) two years additional service credit under the Amended Plan and
the Funded Plan, or successors thereto, of the Company applicable to such
executive on the date of termination. All unvested stock options held by the
executive on the date of the termination shall become immediately vested and all
restrictions on "restricted stock" then held by the executive shall terminate,
except for awards under the 1998 Performance Plan.

     Each employment agreement further provides that, in the event such
executive officer's employment is involuntarily terminated within two years of a
change of control or if the executive officer's employment is voluntarily
terminated within two years of a change of control "for good reason," as defined
in each of the employment agreements, he shall be paid within ten days of such
termination (i) a lump-sum payment equal to three times his base salary at the
then current rate; (ii) a lump-sum payment equal to the sum of (a) three times
the sum of the target bonuses under all of the Company's incentive bonus plans
applicable to such executive for the year in which the termination occurs or the
year in which the change of control occurred, whichever is greater, and (b) if
termination occurs in the fourth quarter of a calendar year, the sum of the
target bonuses under all of the Company's incentive bonus plans applicable to
such executive for the year in which the termination occurs prorated daily based
on the number of days from the beginning of the calendar year in which the
termination occurs to and including the date of termination; and (iii) a
lump-sum payment equal to the amount of any accrued but unpaid bonuses. The
Company (or its successor) shall also provide (i) for a period of three years
continuing coverage and benefits comparable to all life, health and disability
plans of the Company in effect at the time a change of control is deemed to have
occurred; (ii) a lump-sum payment equal to three times the flexible perquisites
amount; and (iii) three years additional service credit under the Amended Plan
and the Funded Plan, or successors thereto, of the Company applicable to such
executive on the date of termination. A change in control shall be deemed to
have occurred if (i) there shall be consummated (a) any consolidation or merger
of the Company in which the Company is not the continuing or surviving
corporation or pursuant to which shares of the Company's Common Stock would be
converted into cash, securities or other property, other than a merger of the
Company where a majority of the Board of Directors of the surviving corporation
are, and for a two-year period after the merger continue to be, persons who were
directors of the Company immediately prior to the merger or were elected as
directors, or nominated for election as director, by a vote of at least
two-thirds of the directors then still in office who were directors of the
Company immediately prior to the merger, or (b) any sale, lease, exchange or
transfer (in one transaction or a series of related transactions) of all or
substantially all of the assets of the Company, or (ii) the shareholders of the
Company shall approve any plan or proposal for the liquidation or dissolution of
the Company, or (iii) (A) any "person" (as such term is used in Sections 13(d)
and 14(d)(2) of the Exchange Act) other than the Company or a subsidiary thereof
or any employee benefit plan sponsored by the Company or a subsidiary thereof,
shall become the beneficial owner (within the meaning of Rule 13d-3 under the
Exchange Act) of securities of the Company representing 20 percent or more of
the combined voting power of the Company's then outstanding securities
ordinarily (and apart from rights accruing in special

                                       19
<PAGE>   22

circumstances) having the right to vote in the election of directors, as a
result of a tender or exchange offer, open market purchases, privately
negotiated purchases or otherwise, and (B) at any time during a period of two
years thereafter, individuals who immediately prior to the beginning of such
period constituted the Board of Directors of the Company shall cease for any
reason to constitute at least a majority thereof, unless the election or the
nomination by the Board of Directors for election by the Company's shareholders
of each new director during such period was approved by a vote of at least
two-thirds of the directors then still in office who were directors at the
beginning of such period.

     Each employment agreement further provides that if remuneration or benefits
of any form paid to them by the Company or any trust funded by the Company
during or after their employment with the Company are excess parachute payments
as defined in Section 280G of the Code, and are subject to the 20 percent excise
tax imposed by Section 4999 of the Code, the Company shall pay Mr. Smith, Mr.
Van Kleef and Mr. Reed a bonus no later than seven days prior to the due date
for the excise tax return in an amount equal to the excise tax payable as a
result of the excess parachute payment and any additional federal income taxes
(including any additional excise taxes) payable by them as a result of the
bonus, assuming that they will be subject to federal income taxes at the highest
individual margin rate.

     The Company has separate Management Stability Agreements ("Stability
Agreements") with Mr. Wormington and Mr. Reardon which are only operative in the
event of a change of control of the Company. The Stability Agreements provide
that, if Mr. Wormington's or Mr. Reardon's employment is involuntarily
terminated within two years of a change of control or if Mr. Wormington or Mr.
Reardon voluntarily terminates their employment within two years of a change of
control "for good reason," as defined in the Stability Agreements, he shall be
paid within ten days of such termination (i) a lump-sum payment equal to two
times his base salary at the then current rate and (ii) a lump-sum payment equal
to the sum of (a) two times the sum of the target bonuses under all of the
Company's incentive bonus plans applicable to Mr. Wormington and Mr. Reardon,
respectively, for the year in which the termination occurs or the year in which
the change of control occurred, whichever is greater, and (b) if termination
occurs in the fourth quarter of a calendar year, the sum of the target bonuses
under all of the Company's incentive bonus plans applicable to Mr. Wormington
and Mr. Reardon, as applicable, for the year in which the termination occurs
prorated daily based on the number of days from the beginning of the calendar
year in which the termination occurs to and including the date of termination.
The Company (or its successor) shall also provide continuing coverage and
benefits comparable to all life, health and disability plans of the Company for
a period of 24 months from the date of termination and Mr. Wormington and Mr.
Reardon would each receive two years additional service credit under the Amended
Plan and the Funded Plan, or successors thereto, of the Company applicable to
such executive on the date of termination. A change of control shall be deemed
to have occurred if (i) there shall be consummated (a) any consolidation or
merger of the Company in which the Company is not the continuing or surviving
corporation or pursuant to which shares of the Company's Common Stock would be
converted into cash, securities or other property, other than a merger of the
Company where a majority of the Board of Directors of the surviving corporation
are, and for a two-year period after the merger continue to be, persons who were
directors of the Company immediately prior to the merger or were elected as
directors, or nominated for election as director, by a vote of at least
two-thirds of the directors then still in office who were directors of the
Company immediately prior to the merger, or (b) any sale, lease, exchange or
transfer (in one transaction or a series of related transactions) of all or
substantially all of the assets of the Company, or (ii) the shareholders of the
Company shall approve any plan or proposal for the liquidation or dissolution of

and 14(d)(2) of the Exchange Act) other than the Company or a subsidiary thereof
or any employee benefit plan sponsored by the Company or a subsidiary thereof,
shall become the beneficial owner (within the meaning of Rule 13d-3 under the
Exchange Act) of securities of the Company representing 20 percent or more of
the combined voting power of the Company's then outstanding securities

(B) at any time during a period of one year thereafter, individuals who

majority thereof, unless the election or the nomination by the Board of
Directors for election by the Company's shareholders of each new

director during such period was approved by a vote of at least two-thirds of the
directors then still in office who were directors at the beginning of such
period, or (iv) there shall be, in the case of Mr. Wormington, (A) a direct or
indirect sale of all or substantially all of the assets of the Company's

business combination, the Company shall cease to have the power to elect a
majority of the Board of Directors (or the other equivalent governing or
managing body) of the entity which acquires, or otherwise controls or conducts
the Company's refining and marketing business.

     In order to participate in the 1998 Performance Plan, the parties to the
employment agreements and management stability agreements described above are
required to acknowledge that the rights and benefits under the 1998 Performance
Plan shall not be deemed an "incentive bonus plan" or other bonus or
compensation arrangement which shall be accelerated, multiplied or otherwise
required to be provided or enhanced under the employment agreement or management
stability agreement.

         2. INCREASE IN THE NUMBER OF SHARES WHICH CAN BE GRANTED UNDER
             THE TESORO PETROLEUM CORPORATION AMENDED AND RESTATED
                EXECUTIVE LONG-TERM INCENTIVE PLAN ("1993 PLAN")

     The Board of Directors is unanimously recommending that the Company's
stockholders approve an amendment to the 1993 Plan which would increase the
total number of shares of Common Stock available for grant under the 1993 Plan
from 4,250,000 to 5,250,000. The increase in the total number of shares
available is necessary because, as of April 5, 2000, only 255,545 shares of
Common Stock were available for grant under the 1993 Plan. The Board of
Directors believes that, based upon advice from its independent compensation
consulting firm, this number is insufficient to provide for the future
participation of employees who are eligible for grants under the 1993 Plan and
is below the market median of shares reserved for stock-based pay. The Board of
Directors has unanimously approved this amendment, subject to stockholder
approval.

     If stock incentives covering the additional 1,000,000 shares of Common
Stock are granted by the Company, participants upon exercise of such grants and
outstanding grants under the 1993 Plan would hold approximately ten percent of
the outstanding Common Stock and securities convertible into Common Stock
(excluding their Common Stock ownership outside of the 1993 Plan). Persons
eligible to participate in the 1993 Plan include all full-time active employees
of the Company and its subsidiaries as determined by the Compensation Committee
of the Board of Directors of the Company. It is presently anticipated that
fourteen executive officers of the Company would be considered eligible to
receive future stock incentives under the 1993 Plan.

     The affirmative vote of the holders of a majority of the outstanding shares
present, or represented, and entitled to vote at the annual meeting is required
to approve the amendment to increase the number of shares which can be granted
under the 1993 Plan. Under Delaware law and the Restated Certificate of
Incorporation and By-laws, Abstentions as to proposal two will have the same
effect as votes against such proposal. Broker Non-Votes, however, will be deemed
shares not entitled to vote on such matters, and therefore will not count as
votes for or against the proposal, and will not be included in calculating the
number of votes necessary for approval of the proposal.

     THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE "FOR" THE
AMENDMENT TO THE TESORO PETROLEUM CORPORATION AMENDED AND RESTATED EXECUTIVE
LONG-TERM INCENTIVE PLAN.

  Summary of the 1993 Plan

     The Executive Long-Term Incentive Plan was approved by the Company's
stockholders at the annual meeting of stockholders held on February 9, 1994, and
replaced the 1982 Plan, although grants under the 1982 Plan that have not been
fully exercised remain outstanding pursuant to their terms. The material

                                       21
<PAGE>   24

provisions of the Executive Long-Term Incentive Plan, as amended on May 5, 1995,
June 6, 1996, and July 29, 1998 (as amended and restated, the "1993 Plan"), are
summarized as follows, but are qualified in entirety by reference to the full
text of the 1993 Plan. Persons eligible to participate in the 1993 Plan include
all full-time, active employees of the Company, including directors who are also
employees of the Company. The 1993 Plan is administered by the Compensation
Committee of the Board of Directors consisting of directors who are not
employees of the Company (the "Compensation Committee"). Subject to the
provisions of the 1993 Plan, the Compensation Committee may, from time to time,
select from all eligible employees, those to whom awards will be granted.

     The 1993 Plan is a flexible plan that gives the Compensation Committee
broad discretion to fashion the terms of awards in order to provide eligible
participants with stock-based incentives as the Compensation Committee deems
appropriate. It permits the issuance of awards in a variety of forms, including
(i) restricted stock, (ii) incentive stock options, (iii) nonqualified stock
options (incentive and nonqualified stock options are referred to collectively
as "options"), (iv) SARs, and (v) performance share and performance unit awards.

     The 1993 Plan provides for the grant of up to 4,250,000 shares of the
Common Stock of the Company which, subject to stockholder approval at this
meeting, will be increased to 5,250,000 shares. The closing price per share of
the Company's Common Stock as traded on the NYSE on April 5, 2000, was
$10 15/16. If any award granted under the 1993 Plan is canceled, terminates,
expires or lapses for any reason, subject to certain limited exceptions, any
shares subject to such award will become available for additional awards under
the 1993 Plan. However, in the event that prior to the award's cancellation,
termination, expiration or lapse, the holder of the award at any time received
one or more "benefits of ownership" pursuant to such award (as defined by the
SEC, pursuant to any rule or interpretation promulgated under Section 16 of the
Exchange Act), the shares subject to such award will not be made available for
regrant under the 1993 Plan. In the event of a stock dividend, stock split,
recapitalization or similar event, the Compensation Committee will equitably
adjust the aggregate number of shares subject to the 1993 Plan, the number of
shares subject to each outstanding award and the exercise prices of outstanding
options.

     The 1993 Plan may be amended, modified or terminated by the Board of
Directors. However, without stockholder approval, no such amendment,
modification or termination may: (a) with limited exceptions, materially
increase the total number of shares which may be issued, (b) materially modify
the eligibility requirements for participation or (c) materially increase the
benefits accruing to participants. Unless earlier terminated by the Board of
Directors or stockholders, the issuance of awards under the 1993 Plan will cease
as of September 15, 2003.

     Stock options granted under the 1993 Plan provide for purchase of shares of
Common Stock at prices determined by the Compensation Committee; provided that
the option price shall not be less than the fair market value thereof on the
date the option is granted unless such option is granted in connection with a
deferral election under the 1993 Plan. The number of stock options that an
individual participant may be granted from the 1993 Plan during any fiscal year
of the Company is limited to 500,000 shares.

     Options granted under the 1993 Plan are exercisable at such times and
subject to such restrictions and conditions as the Compensation Committee shall
approve, but in no event may any option be exercisable prior to six months
following its grant. Options may only be transferred under the laws of descent
and distribution and shall be exercisable only by the participant during the
participant's lifetime. The option exercise price is payable in cash or in
shares of Common Stock having a fair market value equal to the exercise price or
in a combination of cash and such shares. The Compensation Committee may also
allow, along with other means of exercise, cashless exercise as permitted under
the Federal Reserve Board's Regulation T, subject to applicable securities laws.
Upon the death, disability or retirement of a participant, all outstanding
options shall immediately vest and shall be exercisable for the shorter of their
remaining term or one year after termination of employment in the case of death
or disability, and three years after termination of employment in the case of
retirement. Upon termination of employment of a participant for any reason other
than set forth in the preceding sentence, all options held by the participant
which are not vested as of the effective date of termination shall be forfeited
and options which are vested as of the effective date of termination may be

                                       22
<PAGE>   25

exercised for three months following the effective date of termination of
employment; provided, however, the Compensation Committee, in its sole
discretion, may immediately vest all or any portion of the options of a
participant not vested as of such date. If employment of a participant is
terminated by the Company for cause, all outstanding options held by the
participant are forfeited immediately to the Company and no additional exercise
period is allowed, regardless of whether any of the options are vested.

     There are generally no federal tax consequences either to the optionee or
to the Company upon the grant of a stock option. On exercise of an incentive
stock option, the optionee will not recognize any income and the Company will
not be entitled to a deduction for tax purposes, although such exercise may give
rise to liability for the optionee under the alternative minimum tax provisions
of the Code. Generally, if the optionee disposes of shares acquired upon
exercise of an incentive stock option within two years of the date of grant or
one year of the date of exercise, the optionee will recognize compensation
income and the Company will be entitled to a deduction for tax purposes in the
amount of the excess of the fair market value of the shares of Common Stock on
the date of exercise over the stock option exercise price (or the gain on sale,
if less). Otherwise, the Company will not be entitled to any deduction for tax
purposes upon disposition of such shares, and the entire gain for the optionee
will be treated as a capital gain. On exercise of a nonqualified stock option,
the amount by which the fair market value of the Common Stock on the date of
exercise exceeds the stock option exercise price will generally be taxable to
the optionee as compensation income and will generally be deductible for tax
purposes by the Company. The disposition of shares of Common Stock acquired upon
exercise of a nonqualified stock option will generally result in a capital gain
or loss for the optionee but will have no tax consequences for the Company.

     SARs granted under the 1993 Plan may take the form of affiliated SARs,
freestanding SARs, tandem SARs, or any combination of these forms of SARs.
Affiliated SARs may be granted in connection with related stock options and may
be automatically exercised upon exercise of the related stock option, with the
grant price being equal to the option price of the related stock option.
Freestanding SARs may be granted independent of the grant of any stock option
with a grant price at least equal to the fair market value of a share of Common
Stock on the date of grant. Tandem SARs are granted in conjunction with a
related stock option at a grant price equal to the option price of the related
stock option. Either the stock option or the tandem SAR will be adjusted for
exercise of the other since the exercise of a stock option or the tandem SAR
requires the surrender of the right to exercise the equivalent portion of the
stock option or the tandem SAR, as applicable. The term of any SAR granted under
the 1993 Plan may not exceed ten years.

     Upon exercise of an SAR, the participant will receive the difference
between the fair market value of one share of Common Stock on the date of
exercise and the grant price, multiplied by the number of shares with respect to
which the SAR is exercised. Payment due upon exercise of an SAR may be in cash,
in shares of Common Stock having a fair market value equal to the value of the
SAR being exercised, or partly in cash and partly in shares of Common Stock, as
determined by the Compensation Committee in its discretion. The Compensation
Committee may impose restrictions on the exercise of SARs, including the
imposition of window periods for exercise of an SAR for persons required to file
reports pursuant to the provisions of Section 16 of the Exchange Act. Upon the
death, disability or retirement of a participant, all outstanding SARs which are
exercisable on the termination date shall remain exercisable for the shorter of
their remaining term or one year after termination of employment in the case of
death or disability and three years after termination of employment in the case
of retirement. Upon the death, disability or retirement of a participant, all
outstanding SARs which are not exercisable on the termination date shall be
forfeited regardless of whether termination is due to death, disability or
retirement. Upon termination of employment of a participant for any reason other
than set forth in the preceding sentence, all SARs held by the participant which
are not vested as of the effective date of termination shall be forfeited and
SARs which are vested as of the effective date of termination may be exercised
for three months following the effective date of termination of employment;
provided, however, that the Compensation Committee, in its sole discretion, may
immediately vest all or any portion of the SARs of a participant not vested as
of such date. If employment of a participant is terminated by the Company for
cause, all outstanding SARs held by the participant are forfeited immediately to
the Company and no additional exercise period is allowed, regardless of whether
any of the SARs are

                                       23
<PAGE>   26

vested. SARs may only be transferred under the laws of descent and distribution
and shall be exercisable during his or her lifetime only by the participant.

     The Compensation Committee may grant restricted shares of Common Stock to
eligible employees, in such amounts, and subject to such terms and conditions
(which may depend upon or be related to performance goals and other conditions)
as the Compensation Committee shall determine in its discretion. The total
amount of restricted stock which can be awarded during the life of the 1993 Plan
is limited to 750,000 shares of Common Stock. Certificates for the shares of
Common Stock covered by the award shall have appropriate restrictive legends
placed on them with respect to such restrictions. Subject to the applicable
restrictions, the grantee shall have the rights of a stockholder with respect to
such shares. The shares of restricted stock may not be sold, transferred,
pledged, assigned, or otherwise alienated or hypothecated until the end of the
applicable restriction period established by the Compensation Committee or upon
earlier satisfaction of any other conditions specified by the Compensation
Committee in its sole discretion. In addition, no restricted stock granted under
the 1993 Plan may become vested in a participant sooner than six months
following the date of its grant. In the event employment of a participant is
terminated by reason of death, disability or retirement, all unvested shares of
restricted stock shall immediately be forfeited; provided, however, that the
Compensation Committee, in its sole discretion, shall have the right to provide
for accelerated vesting of some or all unvested shares of restricted stock. In
the event employment of a participant shall terminate for any other reason, all
shares of restricted stock held by the participant which are not vested as of
the effective date of the termination of employment shall be immediately
forfeited and returned to the Company; provided, however, that the Compensation
Committee, in its sole discretion, shall have the right, except in the case of
termination of employment for cause, to provide for the lapse of restrictions on
the restricted stock following employment termination, upon such terms and
provisions as it deems proper.

     The Compensation Committee may grant performance shares and performance
units awards to eligible employees, in such amounts, and subject to such terms
and conditions as the Compensation Committee shall in its discretion determine.
The grantee of such awards shall receive payment of the value of performance
shares and performance units earned in cash or shares of Common Stock, or in a
combination of cash and shares of Common Stock, which have an aggregate fair
market value equal to the value of the earned performance shares at the close of
the applicable performance period, in such combination as the Compensation
Committee shall, in its sole discretion, determine. In the event the employment
of a participant is terminated by reason of death, disability, retirement or
involuntary termination without cause during the performance period, the
participant shall receive a prorated payout of the performance units and
performance shares earned, which shall be determined by the Compensation
Committee in its sole discretion, and shall be based upon the length of time the
participant held the award during the performance period and shall be further
adjusted based upon the achievement of the preestablished performance goals.
Such payment in the event of termination shall be made at the same time as
payments are made to participants who did not terminate employment during the
applicable performance period; provided, however, that the Compensation
Committee, in its sole discretion, shall have the power to accelerate the
payment of the performance units and performance shares to participants whose
employment has terminated. In the event that a participant's employment
terminates for any reason other than the foregoing reasons, all performance
units and performance shares shall be forfeited by the participant to the
Company. Performance units and performance shares may not be sold, transferred,
pledged, assigned or otherwise alienated or hypothecated, other than by will or
by the laws of descent and distribution. During the participant's lifetime, the
participant's rights under the 1993 Plan shall be exercisable only by the
participant or the participant's legal representative.

     In the event that (i) any "person," as the term is defined under the
Exchange Act (other than a trustee or other fiduciary holding securities under
an employee benefit plan of the Company, or a corporation owned directly or
indirectly by the stockholders of the Company in substantially the same
proportions as their ownership of stock of the Company), acquires beneficial
ownership of more than 50 percent of the outstanding voting securities, (ii) a
majority of the individuals who constitute the Board of Directors at any time
shall cease to be made up of "qualified directors," and (iii) the stockholders
of the Company approve a merger or consolidation with or involving any other
corporation, other than in a transaction that would result in the voting
securities of the Company outstanding immediately prior to such transaction
continuing to represent at

                                       24
<PAGE>   27

least 50 percent of the outstanding voting securities of the Company immediately
after such transaction, then any stock option or SAR outstanding shall become
fully vested and fully exercisable, any restriction periods and restrictions
imposed on restricted stock shall lapse, the target value obtainable under all
performance units and performance shares shall be deemed to have been fully
earned for the entire performance period and the Compensation Committee may, in
its discretion, make any other modifications to any awards as determined by the
Compensation Committee to be deemed appropriate before the effective date of
such transaction.

     A "qualified director" is a director who meets any of the following
criteria: (1) was a director immediately after the effective date of the
Reclassification (as defined in the Company's Registration Statement of Form
S-4, relating to the 1993 Annual Meeting of Stockholders), including the three
new directors elected in connection therewith; (2) was a director immediately
after the Company's 1994 Annual Meeting of Stockholders; or (3) any director
nominated for election as a director or elected to the Board of Directors by the
directors to fill a vacancy by a vote of directors, and at the time of such
nomination or election at least a majority of the directors were qualified
directors.

                           3. APPOINTMENT OF AUDITORS

     The Board of Directors considers it desirable that its appointment of the
firm of Deloitte & Touche LLP as independent auditors for the Company and its
subsidiaries for fiscal year 2000 be ratified by the stockholders.
Representatives of Deloitte & Touche LLP are expected to be present at the 2000
Annual Meeting of Stockholders and to be available to respond to appropriate
questions. Such representatives will have the opportunity to make a statement at
the annual meeting if they desire to do so. Under Delaware law, the Restated
Certificate of Incorporation and By-laws, a majority of the votes cast are
required to approve the ratification of the appointment of Deloitte & Touche LLP
as auditors. Abstentions and Broker Non-Votes are not votes "cast" on the
question and therefore will not count as votes for or against the proposal, and
will not be included in calculating the number of votes necessary for approval
of the proposal.

     THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE RATIFICATION OF THE
APPOINTMENT OF THE FIRM OF DELOITTE & TOUCHE LLP AS INDEPENDENT AUDITORS FOR THE
COMPANY AND ITS SUBSIDIARIES FOR FISCAL YEAR 2000.

                          4. EXPENSES OF SOLICITATION

     The Company expects to solicit proxies primarily by mail, but directors,
officers and regular employees of the Company may also solicit by personal
interview, telephone or similar means. All expenses in connection with the
solicitation of proxies will be borne by the Company. Arrangements will be made
by the Company for the forwarding, at the Company's expense, of soliciting
materials by brokers, nominees, fiduciaries and other custodians to their
principals. The Company has retained a professional proxy soliciting
organization, Innisfree M&A Incorporated, to aid in the solicitation of proxies
from brokers, bank nominees and other institutional owners, and possibly
individual holders of record of 1,000 shares or more, by personal interview,
telephone or similar means. The Company will pay such organization its customary
fees, estimated not to exceed $8,500, and will reimburse such organization for
certain expenses.

                           5. STOCKHOLDERS' PROPOSALS

     Proposals of stockholders to be presented at the annual meeting to be held
in 2001 must be received for inclusion in the Company's proxy statement and form
of proxy by December 26, 2000.

                                       25
<PAGE>   28

                                6. OTHER MATTERS

     As of the date of this Proxy Statement, management of the Company has no
knowledge of any matters to be presented for consideration at the meeting other
than those referred to above. If any other matters properly come before the
meeting, the persons named in the accompanying form of proxy intend to vote such
proxy to the extent entitled in accordance with their best judgment.

                                            By Order of the Board of Directors,

(a)  Segment operating profit (loss) equals gross operating revenues, gains and
     losses on asset sales and other income less applicable segment costs of
     sales, operating expenses, depreciation and other items. Income taxes,
     interest expense and corporate general and administrative and other
     expenses are not included in determining segment operating profit. In 1998,
     a charge of $19 million for special incentive compensation, of which $7
     million related to operating segments, was classified as corporate other
     expense and not charged to segment operating profit. See Notes C and L of
     Notes to Consolidated Financial Statements.

(b)  In December 1999, the Company sold its U.S. and Bolivian exploration and
     production operations and recorded an aftertax gain of $39.1 million ($1.19
     per diluted share) from the sale of these operations (see Note D of Notes
     to Consolidated Financial Statements). In 1998, these operations incurred
     pretax write-downs of oil and gas properties of $68.3 million ($43.2
     million aftertax or $1.47 per diluted share) and recognized pretax income
     from receipt of contingency funds of $21.3 million ($13.4 million aftertax
     or $0.45 per diluted share). The discontinued operations included $60
     million pretax income ($42 million aftertax or $1.58 per diluted share)
     from termination of a natural gas contract in 1996 and a $33.5 million
     pretax gain ($33.5 million aftertax or $1.33 per diluted share) from the
     sale of certain interests in the Bob West Field in 1995.

(c)  Extraordinary losses on debt extinguishments, net of income tax benefits,
     were $4.4 million ($0.15 per basic and diluted share), $2.3 million ($0.09
     per basic and diluted share) and $2.9 million ($0.12 per basic share, $0.11
     per diluted share) in 1998, 1996 and 1995, respectively. See Note F of
     Notes to Consolidated Financial Statements.

(d)  EBITDA represents earnings before extraordinary items, interest and
     financing costs, income taxes and depreciation, depletion and amortization
     (including oil and gas property write-downs in 1998). While not purporting
     to reflect any measure of the Company's operations or cash flows, EBITDA is
     presented for additional analysis.

(e)  Excluding amounts to fund acquisitions in the Refining and Marketing
     segment in 1998 and the Marine Services segment in 1996.

(f)  In conjunction with the acquisitions in 1998, the Company refinanced its
     existing indebtedness and issued senior subordinated notes and additional
     equity securities, including $165 million of 7.25% Mandatorily Convertible
     Preferred Stock which is included in stockholders' equity. See Note F of
     Notes to Consolidated Financial Statements.

(g)  The Company has not paid dividends on its Common Stock since 1986.

II. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
    OPERATIONS

     Those statements in the Management's Discussion and Analysis that are not
historical in nature should be deemed forward-looking statements that are
inherently uncertain. See "Forward-Looking Statements" on page A-19 for
discussion of the factors which could cause actual results to differ materially
from those projected in such statements.

OVERVIEW

     The Company's strategy is to (i) maximize earnings, cash flows and return
on capital employed and increase its competitiveness by reducing costs,
increasing efficiencies and optimizing existing assets and (ii) expand its
overall market presence through a combination of internal growth initiatives and
selective acquisitions which are both accretive to earnings and provide
significant operational synergies. The Company is further improving
profitability in the Refining and Marketing segment by enhancing processing
capabilities, strengthening marketing channels and improving supply and
transportation functions. The Marine Services segment pursues opportunities for
expansion, as well as optimizing existing operations through development of
customer services and cost management. As part of this strategy, the Company
continues to assess its existing asset base in order to maximize returns and
financial flexibility through diversification, acquisitions and divestitures.
Through redeployment of capital, the Company believes it will create new
shareholder value.

     A major step of this strategy was completed in December 1999 when the
Company sold its exploration and production operations. Although both the
Refining and Marketing and Exploration and Production segments had growth
opportunities, given the Company's strategic objectives and its desire to
improve financial flexibility, management believed that it would not be able to
prudently fund all these opportunities. The sale of the exploration and
production operations generated over $300 million in cash proceeds at closing,
which have been used to repay debt and for other corporate purposes, and allows
the Company to focus on its downstream businesses.

     In 1999, the Company completed its first full year of operating the
refining and marketing assets in Hawaii (acquired in May 1998) and in Washington
(acquired in August 1998). These acquisitions significantly increased Tesoro's
annual revenues and the scope of its Refining and Marketing operations. The
acquisitions positioned Tesoro to participate actively in the atypical market
conditions experienced on the U.S. West Coast which contributed significantly to
profitability in the 1999 second quarter and first half of the 1999 third
quarter. Management believes that, in the first nine months of 1999, the Company
generated synergies among its three refineries of approximately $25 million,
primarily through improvements in marketing, logistics and manufacturing
processes which will continue to benefit Tesoro in the future. As part of the
Company's acquisition strategy, the Company will continue to pursue other
opportunities that are operationally and geographically complementary with its
asset base.

     Management has also developed programs to improve profitability from its
existing asset base. These improvements are focused on manufacturing, marketing
and cost reduction. In manufacturing, management believes that improvements,
such as the installation of a distillate treater in 1999 and the commencement of
a heavy oil conversion project in 2000 at the Washington refinery, will shift
the margin structure of this refinery to a higher, more competitive level. In
addition, marketing improvements, such as forming alliances with high-volume
retail operations like Wal-Mart, will move the Company's products into
higher-value market channels. The Company has initiated an evaluation of its
cost structure, with specific emphasis on the Alaska operations. Concurrent with
the broad-based cost review, a full range of options relative to marketing
products in Alaska, such as supplying the Alaska market from other sources, will
be evaluated as well as a restructuring that could include the sale, or closure
of part, or all, of the Alaskan assets. Management expects to complete this
review by April 30, 2000.

BUSINESS ENVIRONMENT

     The Company operates in an environment where its results and cash flows are
sensitive to volatile changes in energy prices. Fluctuations in the cost of
crude oil used for refinery feedstocks and the price of refined products can
result in changes in margins from the Refining and Marketing operations, as
prices received for refined products may or may not keep pace with changes in
crude oil costs. The Company also purchases refined products manufactured by
others that are later resold; changes in price levels of refined products can
result in changes in margins on such activities. Energy prices, together with
volume levels, also determine the carrying value of crude oil and refined
product inventory. The Company uses the last-in, first-out ("LIFO") method of
accounting for inventories of crude oil and refined products in its Refining and
Marketing segment. This method results in inventory carrying amounts that are
less likely to represent current values and in costs of sales which more closely
represent current costs.

     Changes in crude oil and natural gas prices also influence the level of
drilling activity in the Gulf of Mexico. The Company's Marine Services segment,
whose customers include offshore drilling contractors and related industries,
can be impacted by significant fluctuations in natural gas, condensate and oil
prices. The Company's Marine Services segment uses the first-in, first-out
("FIFO") method of accounting for inventories of fuels. Changes in fuel prices
can significantly impact inventory valuations and costs of sales in this
segment.

RESULTS OF OPERATIONS

SUMMARY

     Tesoro's earnings from continuing operations for 1999 were $32.2 million
($0.62 per basic and diluted share), compared with $7.6 million ($0.05 per basic
and diluted share) in 1998 and $2.4 million ($0.09 per basic and diluted share)
in 1997. On a per share basis, net earnings for 1999 and 1998 were impacted by
the issuance of preferred stock and additional shares of common stock in
mid-1998. The improvement in 1999 earnings was mainly due to higher operating
profit from the Company's Refining and Marketing segment. Increased throughput
and sales volumes from operations acquired in mid-1998, refinery efficiency and
reliability, and profits from purchasing and selling products manufactured by
others contributed to the Refining and Marketing results. Partially offsetting
these improvements were increased general and administrative expenses and
interest and financing costs during 1999. See table below for significant items
affecting comparability which occurred in 1998.

     Tesoro's net earnings for 1999 were $75.0 million ($1.94 per basic share
and $1.92 per diluted share), compared to a net loss of $19.4 million ($0.86 per
basic and diluted share) in 1998 and net earnings of $30.7 million ($1.16 per
basic share and $1.14 per diluted share) in 1997. In 1998, the Company incurred
an aftertax extraordinary loss of $4.4 million for early extinguishment of debt.
During 1999, discontinued operations contributed $42.8 million to net earnings,
including an aftertax gain of $39.1 million from the sale of these operations.
In 1998, discontinued operations incurred a net loss of $22.6 million, which
included $43.2 million in aftertax write-downs of oil and gas properties and
$13.4 million in aftertax income from receipt of contingency funds related to
these operations.

(a) Represents throughput at the Company's refineries times refinery system
    product spread.

<PAGE>   37

(b) Non-refinery margin includes merchandise margins, margins on products
    purchased and resold, and adjustments due to selling a volume and mix of
    product that is different than actual volumes manufactured.

(c) Volumes for 1999 and 1998 include amounts from the Hawaii operations
    (acquired in May 1998) and the Washington refinery (acquired in August 1998)
    averaged over the periods presented. Certain amounts have been reclassified
    to conform with the current presentation.

(d) Refinery system product spread represents an average for the Company's three
    refineries. For 1999, the Company's refinery spread per barrel by refinery
    was approximately $4.74 for Alaska, $4.80 for Hawaii and $6.41 for
    Washington.

(e) Beginning in the fourth quarter of 1999, the Company identified
    industry-posted price information to calculate an indicator margin. This
    indicator margin is an analytical tool which may provide an indication of
    the direction and magnitude of changes in market conditions that may be
    representative of market changes which impact Tesoro's refinery system. It
    is a component, but not a predictor, of Tesoro's actual refinery spread.
    Other factors including, but not limited to, throughput volumes and mix,
    yield percentages and inventory changes, determine actual refinery spread.
    For 1999, the indicator margin was approximately equal to Tesoro's actual
    refinery system product spread of $5.79 per barrel. The indicator margin
    utilizes industry-posted prices, such as Pacific Northwest gasoline and
    diesel fuel prices; Los Angeles jet fuel prices; Seattle industrial fuel oil
    prices; Alaska North Slope crude oil prices; and West Texas intermediate
    crude oil prices. The indicator margin is posted weekly on the Company's
    website at www.tesoropetroleum.com/investor/indicator_margin.html.

(f) Sources of total product sales included products manufactured at the
    Company's refineries, products drawn from inventory balances and products
    purchased from third parties.

(g) Gross margins on product sales included margins on sales of manufactured and
    purchased products and the effects of inventory changes.

     1999 Compared with 1998. Segment operating profit for the Company's
Refining and Marketing operations was $122.4 million in 1999, an increase of
$52.7 million from segment operating profit of $69.7 million in 1998.
Contributing to the increase was a full year of results from the Washington
refinery and related marketing operations in 1999, compared to five months in
1998. Similarly, the Hawaii refinery and operations contributed to operating
profit for the full year in 1999; however, the 1999 results were lower than in
the seven months included in 1998.

     Segment operating profit increased significantly during the 1999 second
quarter and first half of the 1999 third quarter due primarily to stronger than
normal market conditions on the West Coast. Refining margins during this period
were strong in the western U.S. due to seasonal demand, product supply
disruptions caused by operating problems at other refineries, and a rupture of
the major refined products pipeline which serves the Pacific Northwest region.
However, in the fourth quarter of 1999, margins were adversely impacted as
industry refining capacity on the West Coast came back on-line, refined product
imports into the West Coast continued, and crude costs escalated rapidly. The
Company's refinery-system product spread, which averaged approximately $8.07 per
barrel in the month of July 1999 and $7.16 per barrel in the month of August
1999, dropped precipitously during the 1999 fourth quarter to approximately
$4.30 per barrel in the month of December 1999. In addition, during the 1999
fourth quarter, lower refinery throughputs, caused primarily by the scheduled
turnaround of the Washington refinery's crude distillation and catalytic
reformer units for 25 days in October, reduced overall system throughput to an
average of 208,100 barrels per day. Management estimates that, had the Company
been able to operate the Washington refinery during the turnaround, an
additional $8 million in segment operating profit would have been realized
during the 1999 fourth quarter.

     Revenues from sales of refined products in the Refining and Marketing
segment increased in 1999, primarily due to the higher sales volumes from the
acquisitions, higher product prices and increased sales volumes of purchased
product. The increase in other revenues during 1999 included higher retail
merchandise sales, primarily from the Hawaii acquisition, and $4.5 million in
revenues from the sub-charter of vessels to

                                       A-9
<PAGE>   38

third parties, partially offset by lower crude oil resales. The increase in
costs of sales reflected higher volumes associated with the acquisitions,
increased prices for feedstock and products, and higher purchased product
volumes. During 1999, the Company reduced inventory levels by approximately 2.5
million barrels from the prior year-end level, resulting in a liquidation of
LIFO inventory quantities carried at lower costs prevailing in previous years.
This LIFO liquidation resulted in a decrease in costs of sales of $8.4 million
pretax in 1999.

     During 1999, the Refining and Marketing segment benefited from the
Company's focus on manufacturing efficiency and reliability, as well as
distribution costs and marketing flexibility. The Company maintained a flexible
supply of crude oils and other feedstocks and operated the refineries at
economic rates, which all contributed to the improvement in operating profit.
Throughput for the Company's refinery-system averaged 233,700 barrels per day
during 1999, which included 39% foreign crude oil, 28% Alaska North Slope crude
oil, 18% Canadian crude oil, 13% Alaska Cook Inlet crude oil and 2% intermediate
feedstocks. Overall refinery gross margin increased to $494.1 million in 1999
due to the higher throughput volumes and an increase in average refinery system
product spread per barrel to $5.79 in 1999 compared to $5.67 per barrel in 1998.
During 1999, products from the Company's refineries accounted for approximately
83% of its sales volume, compared with 91% in 1998.

     Margins from non-refinery activities increased to $62.4 million in 1999 due
primarily to higher sales of purchased refined products and increased
merchandise sales. Included in non-refinery margin was approximately $32.5
million from sales of purchased refined product compared to $3.8 million in the
prior year. Operating expenses and depreciation and amortization increased in
1999 primarily due to the acquisitions.

     Outlook and Other Factors. During the 1999 fourth quarter, the Company
completed the installation of a distillate treater at the Washington refinery
which will enable the refinery to increase its production of low-sulfur diesel
fuel and jet fuel beginning in the first quarter of 2000. The distillate treater
installation, together with licensing fees and supporting infrastructure, cost
approximately $13 million. Management believes that the distillate treater
installation will add between $6 million to $8 million to annual operating
profit. Other significant investment projects and capital spending plans to
improve the Company's profitability are discussed in "Liquidity and Capital
Resources -- Capital Spending."

     In 1999, the Company entered into a charter for a double-hull tanker to be
used for transporting crude oil and refined products. Under the terms of the new
charter, Tesoro will receive one of the new Lightship Class tankers. The new
charter, which has a three-year primary term beginning in May 2000 and two
one-year options, will require future minimum annual lease payments of
approximately $10 million. The new charter will save the Company approximately
$6 million annually when it replaces the Chesapeake Trader, which goes off
charter to Tesoro in May 2000. Tesoro has another ship under charter, the
Potomac Trader, which goes off charter to Tesoro in September 2000. Management
is continuing to evaluate the Company's requirements for chartered vessels and
believes that, based on current market conditions, shipping costs will be
further reduced in 2000 and 2001.

     For the year 2000, management estimates, based on current operations, that
the Company's refinery-system throughput will average approximately 260,000
barrels per day and refined products manufactured will average 270,000 barrels
per day, subject to seasonality experienced during the interim periods. One
maintenance turnaround is scheduled in 2000 for the hydrocracker and catalytic
reformer units at the Hawaii refinery. Feedstock for the refineries is expected
to consist of approximately 42% crude oil from foreign sources, 25% crude oil
from Alaska's North Slope, 15% crude oil from Canada, 12% crude oil from
Alaska's Cook Inlet and 6% intermediate feedstocks. The Company's
refinery-system yield, based on current operations, is expected to consist of
approximately 36% gasoline, 26% jet fuel, 15% diesel fuel and 23% heavy oils and
other products during 2000.

     The Company improved the fundamental earnings potential of its Refining and
Marketing segment with the acquisitions in 1998 and the realization of synergies
in 1999. The Company is further improving profitability by enhancing processing
capabilities, strengthening marketing channels and improving supply and
transportation functions. In addition, the Company has initiated an evaluation
of its cost structure, with specific emphasis on the Alaska operations. Future
profitability of this segment, however, will continue to be

                                      A-10
<PAGE>   39

influenced, either positively or negatively, by market conditions and other
additional factors that are beyond the control of the Company.

     1998 Compared with 1997. Segment operating profit from the Refining and
Marketing operations totaled $69.7 million in 1998, an increase of $49.2 million
from segment operating profit of $20.5 million in 1997. The increase in segment
operating profit was primarily due to higher throughput and sales volumes from
the acquired refineries and improved refined product yields in Alaska. Financial
results from the acquired operations have been included since the dates of
acquisition. The Hawaii acquisition was completed on May 29, 1998, and the
Washington acquisition was completed on August 10, 1998. These acquisitions
contributed positively to the segment's operating profit in 1998; however, on a
consolidated basis, these results were largely offset by increased corporate
interest and financing costs.

     During 1998, the Company's refined product yields in Alaska benefited from
an expansion of the hydrocracker unit completed in October 1997. The expansion,
which increased the unit's capacity by approximately 25%, enables production of
more jet fuel. Segment results were favorably impacted by this expansion
beginning in the fourth quarter of 1997. During 1998, average throughput at the
Alaska refinery increased by 7,400 barrels per day, a 15% increase over 1997
which included a 30-day maintenance turnaround. Production of jet fuel at this
refinery increased by approximately 30% over 1997 due to the hydrocracker
expansion and higher throughput levels.

     The Alaska hydrocracker expansion and the acquisitions contributed to an
increase in the proportion of higher value gasoline and middle distillates
manufactured by the Company in 1998. Conversely, the proportion of lower value
heavy oils and residual products manufactured by the Company decreased in 1998.
The higher-value mix of product partly offset market pressures which decreased
year-to-year refinery product spreads to $5.67 per barrel in 1998 from $6.38 per
barrel in 1997. Increased gross margin of $5.07 per barrel in 1998, which
compare to $4.84 per barrel in 1997, reflected the higher-value mix of
manufactured product and a reduction in products purchased and resold. In 1998,
products from the Company's refineries accounted for approximately 91% of its
sales volume, compared with 78% in 1997.

     Revenues from sales of refined products in the Refining and Marketing
segment increased during 1998 primarily due to the higher sales volumes from the
acquisitions, partially offset by lower sales prices. Export sales of refined
products increased to $35.5 million in 1998, compared with $16.1 million in
1997, primarily due to sales from Hawaii to Asia partly offset by a decrease in
exports from the Alaska refinery to the Far East. Other revenues included crude
oil resales of $29.9 million in 1998 compared to $44.4 million in 1997.
Merchandise sales, also included in other revenues, increased in 1998 due to the
Hawaii acquisition which included 30 Company-operated retail stations. The
increase in costs of sales reflected higher volumes associated with the
acquisitions, partly offset by lower feedstock prices. Margins from non-refinery
activities increased to $22.6 million in 1998, compared with $13.0 million in
1997, primarily due to the higher merchandise sales. Operating expenses and
depreciation and amortization were higher in 1998 primarily due to the
acquisitions.

</TABLE>

     1999 Compared with 1998. Total segment operating profit for Marine Services
was $8.6 million for 1999, unchanged from 1998. Of this operating profit, $0.6
million was earned in the first half of 1999 and $8.0 million was earned in the
last half of 1999. The Marine Services operations in the Gulf of Mexico, which
are largely dependent on the level of oil and gas drilling, workover,
construction and seismic activity in the Gulf, were negatively impacted by the
low level of drilling activity during the first half of 1999. However, the
business climate improved during the latter half of 1999 with the number of
drilling rigs served by Tesoro's terminals increasing to a high of 35 as
compared to eight in March 1999. The recovery by the Company in the last half of
1999 was due in part to the increased drilling activity and better cost
management.

     Also contributing to the segment's operating profit primarily in the last
half of 1999 were the West Coast marine operations which the Company purchased
on June 17, 1999. This purchase of the U.S. West Coast marine fuels operations
of BP Marine, a division of BP Amoco PLC, included inventory and leased
facilities at Port Angeles and Seattle, Washington, and Portland, Oregon, and
expanded the Marine Services segment's presence on the West Coast. These
operations, which were included in the Marine Services segment since the date of
purchase, contributed $62.3 million to revenues, 126.9 million gallons to fuel
sales volumes and $2.6 million to segment operating profit in 1999.

     Excluding the impact of the new West Coast operations, revenues for Marine
Services would have been unchanged and segment operating profit would have
declined by $2.6 million in 1999 as compared with 1998. The effect of higher
spot fuel prices on revenues was offset by declines in volumes. The decline in
Gulf of Mexico operating profit was mainly due to lower fuel sales volumes and
other product margins. The increase in the segment's operating expenses and
other during 1999 reflected the additional West Coast operations. In 1999, both
the West Coast and Gulf of Mexico operations benefited from low costs of
inventories.

     In March 2000, management commenced a realignment of its operational
organization which includes the transfer of the Marine Services segment's West
Coast operations to the Refining and Marketing segment.

     1998 Compared with 1997. Gross operating revenues decreased 10% from $132.2
million in 1997 to $118.6 million in 1998, reflecting a $13.4 million decline in
fuel revenues from lower market prices partly offset by a 16% increase in fuel
sales volumes. The increase in fuel volumes was attributable to operations in
the Gulf of Mexico and the transfer of three West Coast terminals from the
Company's Refining and Marketing segment to Marine Services in January 1998. The
decrease in costs of sales also reflected lower fuel prices, partly offset by
increased volumes. Gross profit, which improved by $4.1 million due to higher
volumes, was partly offset by additional operating expenses from the West Coast
terminals and higher depreciation and

                                      A-12
<PAGE>   41

amortization resulting from upgrades to facilities. Despite lower rig activity
in the Gulf of Mexico, total segment operating profit increased by $2.3 million
largely due to the Company's ability to emphasize customer service, control
expenses and increase sales volumes.

GENERAL AND ADMINISTRATIVE EXPENSES

     General and administrative expenses were $34.1 million in 1999, compared
with $19.7 million in 1998 and $13.6 million in 1997. The $14.4 million increase
in 1999 was primarily due to costs related to the implementation of an
integrated enterprise-wide information system and higher employee costs
associated with business development and personnel realignment. When comparing
1998 to 1997, the increase was primarily due to higher employee costs and
professional fees partly due to the design phases of the system implementation
which commenced in 1998.

INTEREST AND FINANCING COSTS

     Interest and financing costs totaled $37.6 million in 1999, compared with
$25.2 million in 1998 and $8.1 million in 1997. The $12.4 million increase in
1999, compared to 1998, was primarily due to a full year's interest on the 9%
Senior Subordinated Notes, which were issued to finance the acquisitions in
1998. The $17.1 million increase in 1998, compared to 1997, was primarily due to
higher borrowings under the Company's credit arrangements and the issuance of
debt securities in July 1998 which were used to fund acquisitions, to refinance
debt and obligations and for other corporate purposes (see Note F of Notes to
Consolidated Financial Statements).

     Corporate interest expense allocated to discontinued operations was based
on net assets and amounted to $10.6 million, $7.8 million and $0.2 million in
1999, 1998 and 1997, respectively. See Note D of Notes to Consolidated Financial
Statements. Interest and financing costs reported in the Company's Statements of
Consolidated Operations is after the allocation to discontinued operations.

OTHER EXPENSE

     Other expense totaled $9.3 million in 1999, compared with $23.3 million in
1998 and $3.3 million in 1997. In 1999, other expense included a $3 million
provision for settlement of claims by the State of Hawaii (see Note M of Notes
to Consolidated Financial Statements) and increased corporate depreciation. In
1998, the Company incurred a charge for special incentive compensation which was
earned in the second quarter when the market price of the Company's Common Stock
achieved a specific performance target (see Note L of Notes to Consolidated
Financial Statements). This charge totaled $19 million, of which $7 million
related to operating segment employees. There was no material comparable charge
recorded in 1997.

INCOME TAX PROVISION

     Income taxes on continuing operations increased to $19.0 million in 1999,
from $4.5 million in 1998 and $1.0 million in 1997. This increase was due to the
higher pretax earnings from continuing operations. The Company's effective
income tax rates were 37%, 37% and 32% in 1999, 1998 and 1997, respectively. See
Note G of Notes to Consolidated Financial Statements for further information on
income taxes and Note D for income taxes related to discontinued operations.

DISCONTINUED OPERATIONS

     Earnings from discontinued operations in 1999 of $42.8 million (net of
income tax expense of $29.6 million), or $1.30 per diluted share, included
aftertax operating results of $3.7 million from the Company's U.S. and Bolivian
exploration and production operations up until the closing dates of the sales of
these operations and a $39.1 million aftertax gain on the sale of these
operations in December 1999. Prior periods have been restated to reflect the
exploration and production business as discontinued operations. In 1998,
discontinued operations had a net loss of $22.6 million, or $0.76 per diluted
share, which included aftertax write-downs of oil and gas properties of $43.2
million and aftertax income of $13.4 million for the

                                      A-13
<PAGE>   42

receipt of contingency funds from an operator. Discontinued operations
contributed $28.3 million to net earnings in 1997. See Note D of Notes to
Consolidated Financial Statements for further information on allocated interest
expense and income taxes related to discontinued operations.

CAPITAL RESOURCES AND LIQUIDITY

OVERVIEW

     The Company's primary sources of liquidity are cash flows from operations
and borrowing availability under a revolving line of credit. Capital
requirements are expected to include capital expenditures, working capital, debt
service and preferred dividend requirements. Based upon current needs,
management believes that the available capital resources will be adequate to
meet its capital requirements.

     The Company operates in an environment where its liquidity and capital
resources are impacted by changes in supply of and demand for crude oil and
refined petroleum products, market uncertainty and a variety of additional risks
that are beyond the control of the Company. These risks include, among others,
the level of consumer product demand, weather conditions, fluctuations in
seasonal demand, governmental regulations, the price and availability of
alternative fuels and overall market and economic conditions. The Company's
future capital expenditures, as well as borrowings under its credit arrangements
and other sources of capital, will be affected by these conditions.

CAPITALIZATION

     The Company's capital structure at December 31, 1999, was comprised of the
following (in millions):

<TABLE>

</TABLE>

     In addition, at December 31, 1999, the Company had cash and cash
equivalents of $142 million, which included a portion of the proceeds from the
sale of the exploration and production operations. At December 31, 1999, the
Company's total debt to capitalization ratio was 40%, while debt, net of cash,
to capitalization was 31%. In March 2000, the Company repaid the Tranche B Term
Loan and the BHP Note.

     The Senior Credit Facility, Senior Subordinated Notes and Preferred Stock,
as defined below, impose various restrictions and covenants on the Company that
could potentially limit the Company's ability to respond to market conditions,
to provide for anticipated capital investments, to raise additional debt or
equity capital or to take advantage of business opportunities.

     For further information on the Company's capital structure, see Note F of
Notes to Consolidated Financial Statements.

CREDIT ARRANGEMENTS

     The Company has financing and credit arrangements under a three-year senior
credit facility ("Senior Credit Facility"), dated July 2, 1998, with a
consortium of banks. The Senior Credit Facility was comprised of term loan
facilities aggregating $200 million ("Term Loans") and a $300 million revolving
credit and letter of credit facility ("Revolver"). In April 1999, the Company
reduced commitments under the Revolver from

                                      A-14
<PAGE>   43

$300 million to $175 million, reducing commitment fees. The Company used a
portion of the proceeds from the sale of its exploration and production
operations to prepay $97.4 million of the Term Loans in December 1999 and $80.9
million of Term Loans in March 2000. Based on current needs, the Company
believes that the remaining credit capacity of $175 million under the Revolver,
together with existing cash and internally-generated cash flows, is sufficient
to fund capital expenditures and working capital requirements. At December 31,
1999, unused availability under the Senior Credit Facility was approximately
$172 million.

     The Senior Credit Facility requires the Company to maintain specified
levels of consolidated leverage and interest coverage and contains other
covenants and restrictions customary in credit arrangements of this kind. The
Company was in compliance with these covenants at December 31, 1999. The terms
of the Senior Credit Facility allow for payment of cash dividends on the
Company's Common Stock not to exceed an aggregate of $10 million in any year and
also allow for payment of required dividends on its 7.25% Mandatorily
Convertible Preferred Stock. The Senior Credit Facility is guaranteed by
substantially all of the Company's active direct and indirect subsidiaries
("Guarantors") and is secured by substantially all of the domestic assets of the
Company and each of the Guarantors.

     For further information concerning debt maturities and restrictions and
covenants, see Note F of Notes to Consolidated Financial Statements.

DEBT SERVICE AND PREFERRED DIVIDENDS

     The Company's funded debt obligations as of December 31, 1999 totaled $418
million. After the repayments in March 2000, discussed above, the Company's
total debt was reduced to approximately $313 million, primarily consisting of
the 9% Senior Subordinated Notes due 2008, Series B ("Senior Subordinated
Notes"). The Senior Subordinated Notes, which were issued in 1998 at an
aggregate principal amount of $300 million, have a ten-year maturity without
sinking fund requirements and are subject to optional redemption by the Company
after five years at declining premiums. The indenture for the Senior
Subordinated Notes contains covenants and restrictions which are customary for
notes of this nature. These covenants and restrictions are less restrictive than
those under the Senior Credit Facility.

     The Company has 10,350,000 Premium Income Equity Securities ("PIES")
outstanding, which represent fractional interests in the Company's 7.25%
Mandatorily Convertible Preferred Stock ("Preferred Stock"). Holders of PIES are
entitled to receive a cash dividend. The PIES will automatically convert into
shares of Common Stock on July 1, 2001, at a rate based upon a formula dependent
upon the market price of Common Stock at the time of conversion. Before July 1,
2001, each PIES is convertible, at the option of the holder thereof, into 0.8455
shares of Common Stock, subject to adjustment in certain events.

COMMON STOCK SHARE REPURCHASE PROGRAM

     In February 2000, the Company's Board of Directors authorized the
repurchase of up to 3 million shares of Tesoro Common Stock, which represents
approximately 9% of the 32.4 million shares then outstanding. Under the program,
the Company will repurchase Tesoro Common Stock from time to time in the open
market and through privately negotiated transactions. Purchases will depend on
price, market conditions and other factors and will be made primarily from
internally-generated cash flow. The stock may be used to meet employee benefit
plan requirements and other corporate purposes. Under the program, the Company
has repurchased 718,600 shares of Common Stock for approximately $6.8 million
through March 20, 2000.

CAPITAL SPENDING

     During 1999, the Company's capital expenditures totaled $141 million ($85
million for continuing operations and $56 million for discontinued operations)
that were funded primarily with internally-generated cash flows. Capital
improvements for the Refining and Marketing segment during 1999 totaled $71
million, which included the installation of a distillate treater at the
Washington refinery, acquisition of a terminal in Alaska, retail gas station
projects and various other refinery and terminal improvements. Other capital
spending for continuing operations during 1999 was primarily related to the
implementation of an integrated enterprise-wide information system and purchase
of the West Coast marine fuel operations. Capital
                                      A-15
<PAGE>   44

expenditures for the discontinued exploration and production operations were
primarily for drilling wells in the U.S. and Bolivia.

     For 2000, the Company has initiated two significant capital investment
projects. First, Tesoro's Board of Directors has approved funding for a heavy
oil conversion project at the Washington refinery. Management believes that this
project, which has an estimated total cost of $75 million to $80 million, will
be completed in late 2001. Management expects to spend approximately $28 million
of the total cost in the year 2000. Secondly, the Company has entered into an
agreement with Wal-Mart Stores, Inc. to build and operate retail fueling
facilities on sites at selected existing and future Wal-Mart store locations in
eleven western states. In the initial phase of this program, the Company plans
to build 30 to 40 facilities, each with an estimated cost of approximately
$500,000. On March 2, 2000, the Company accepted the first 14 sites offered by
Wal-Mart. See Note M of Notes to Consolidated Financial Statements.

     The Company's total capital program for 2000 is $115 million. Tesoro plans
to spend $72 million for projects at its refineries, including $28 million for
the conversion project, $20 million for other economic projects, $13 million for
sustaining capital, $8 million for environmental projects and $3 million for
health and safety projects. Tesoro's retail capital program is planned at $36
million, of which $32 million is for economic projects. The retail capital
program will fund new station construction under the terms of the agreement with
Wal-Mart, improvements to existing company-owned and operated stations at other
sites, expansion of Tesoro's dealer/jobber network, and construction of other
new company-owned and operated sites. Tesoro's retail program will target growth
in the western U.S. The Marine Services segment has a $5 million capital budget,
which includes $2 million of economic capital. Corporate capital expenditures
are planned at $2 million, primarily for upgrades to information systems
software and technology.

     Management plans to fund its capital program in 2000 with existing cash and
internally-generated cash flows, which should preserve the Company's financial
condition and permit the Company to pursue other growth opportunities.

MAJOR MAINTENANCE COSTS

     In 1999, the Company incurred a total of $22 million in major maintenance
costs and catalyst changes associated with two refinery turnarounds. In May
1999, the Company incurred $9 million at its Alaska refinery. The costs of this
turnaround are being amortized over a 24-month period until the next turnaround
which is projected to occur in 2001. In October 1999, the Company incurred $13
million of turnaround costs at its Washington refinery. The costs of this
turnaround, which included the Washington refinery's crude distillation and
catalytic reformer units, are being amortized over a 48-month period until the
next turnaround of these units which is projected to occur in 2003. Amortization
of turnaround costs, other major maintenance projects and catalysts totaled $27
million in 1999.

     For 2000, the Company has scheduled a turnaround, including catalyst
change, for certain units at its Hawaii refinery. The total cost is estimated at
$8 million. Amortization of turnaround costs, other major maintenance costs and
catalysts for 2000 are projected to total $24 million.

</TABLE>

     During 1999, net cash from operating activities totaled $113 million, $85
million from continuing operations and $28 million from discontinued operations.
Continuing operations provided cash flows from earnings (discussed in "Results
of Operations" above) before depreciation and amortization and other non-cash
charges partially offset by increased working capital requirements. During 1999,
working capital

                                      A-16
<PAGE>   45

requirements increased due to higher receivables arising in part from higher
commodity prices, partially offset by correlating changes in payables and a
reduction in inventory levels. Net cash from investing activities of $166
million in 1999 was provided by net proceeds of $309 million from the sale of
assets, primarily the exploration and production operations, partially offset by
capital expenditures of $85 million for continuing operations and $56 million
for discontinued operations. Net cash used in financing activities of $149
million in 1999 primarily represented repayments of debt, including $123 million
of Term Loans and other obligations, $61 million of net repayments under the
Revolver, and payments of dividends on Preferred Stock of $15 million. These
uses of cash in financing activities were partially offset by the issuance of
$50 million of Term Loans in January 1999. Gross repayments under the Revolver
amounted to $550 million, while gross borrowings amounted to $489 million.

     Working capital totaled $290 million at December 31, 1999, compared to $182
million at year-end 1998. Included in working capital at year-end 1999 were cash
and cash equivalents of $142 million, which included remaining proceeds received
from the sale of discontinued operations that were being held by the Company for
general corporate purposes. Subsequent to year-end 1999, proceeds have been used
to repay debt.

     During 1998, net cash from operating activities totaled $122 million, $51
million from continuing operations and $71 million from discontinued operations.
Continuing operations provided cash flows from earnings before depreciation and
amortization and other non-cash charges and from changes in working capital and
other net assets. Cash flows from discontinued operations were due to positive
earnings before depreciation, depletion and amortization and write-downs of oil
and gas properties together with the receipt of $21 million pretax from an
operator, representing contingency funds from an operator that were no longer
needed. Net cash used in investing activities of $719 million in 1998 included
$536 million for acquisitions and $185 million for capital expenditures ($50
million for continuing operations and $135 million for discontinued operations).
Net cash from financing activities of $607 million in 1998 primarily included
net proceeds of $533 million from the issuance of equity and debt securities and
$150 million from Term Loans, partially offset by net repayments of other debt.
Gross borrowings under revolving credit lines and interim credit facility
amounted to $944 million, while repayments totaled $916 million. Payments of
dividends on Preferred Stock totaled $3 million in 1998. At December 31, 1998,
the Company's working capital totaled $182 million, including cash and cash
equivalents of $12 million, compared with working capital of $62 million at
year-end 1997.

     During 1997, net cash from operating activities totaled $91 million, $14
million from continuing operations and $77 million from discontinued operations.
Continuing operations provided cash flows from earnings before depreciation and
amortization and other non-cash charges partially offset by working capital and
other requirements. Cash flows from discontinued operations were generated by
positive earnings before depreciation, depletion and amortization. Net cash used
in investing activities of $151 million in 1997 included capital expenditures of
$93 million for discontinued operations, $44 million for refining and marketing
projects and $9 million for upgrades in marine services. Net cash from financing
activities of $41 million in 1997 included net borrowings of $28 million under a
former credit facility and receipt of $16 million under a loan for the
hydrocracker expansion, partially offset by payments of other long-term debt and
repurchases of Common Stock. During 1997, gross borrowings under the Company's
former credit facility were $150 million, with $122 million of repayments.

ENVIRONMENTAL

     The Company is subject to extensive federal, state and local environmental
laws and regulations. These laws, which change frequently, regulate the
discharge of materials into the environment and may require the Company to
remove or mitigate the environmental effects of the disposal or release of
petroleum or chemical substances at various sites or install additional controls
or other modifications or changes in use for certain emission sources. The
Company is currently involved in remedial responses and has incurred cleanup
expenditures associated with environmental matters at a number of sites,
including certain of its own properties. At December 31, 1999, the Company's
accruals for environmental expenses amounted to $13.6 million. Based on
currently available information, including the participation of other parties or
former owners in remediation actions, the Company believes these accruals are
adequate. To comply with
                                      A-17
<PAGE>   46

environmental laws and regulations, the Company anticipates that it will make
capital improvements of approximately $8 million in 2000 and $10 million in
2001. The Company is currently evaluating certain proposed revisions to the
Clean Air Act regulations which would require a reduction in the sulfur content
in gasoline fuel manufactured at its refineries. The Company expects that it
will make capital improvements to certain equipment at its Washington refinery
to meet the revised gasoline standard. Additional proposed changes to the Clean
Air Act regulations may include new emission controls at certain processing
units at each of the Company's refineries. The Company anticipates that the
revisions to the Clean Air Act will become effective over the next three to five
years and that, based on known current technology, it could spend approximately
$25 million to $30 million to comply with these proposed revisions.

     Conditions that require additional expenditures may exist for various
Company sites, including, but not limited to, the Company's refineries, retail
gasoline stations (operating and closed locations) and petroleum product
terminals, and for compliance with the Clean Air Act and other state and federal
regulations. The amount of such future expenditures cannot currently be
determined by the Company. For further information on environmental
contingencies, see Note M of Notes to Consolidated Financial Statements.

YEAR 2000 READINESS DISCLOSURE

     The efficient operation of the Company's business is dependent on its
computer hardware, operating systems and software programs (collectively,
"Systems and Programs"). These Systems and Programs are used in several key
areas of the Company's business, including production and distribution,
information management services and financial reporting, as well as in various
administrative functions. The goal of the Company's Year 2000 program was to
prevent any disruption to the Company's business process or its ability to
conduct business resulting from Year 2000 computer issues.

     To identify and eliminate potential disruptions, the Company developed a
Year 2000 compliance plan ("Compliance Plan") with respect to those Systems and
Programs that were deemed to be critical to the Company's operations and safety.
The Company utilized both internal and external resources in evaluating its
Systems and Programs, as well as manual processes, external interfaces with
customers and services supplied by vendors, to identify potential Year 2000
compliance problems. The Company identified and replaced a number of Systems and
Programs that were not Year 2000 compliant. Modification or replacement of the
Company's Systems and Programs was performed in-house by Company personnel and
external consultants.

     The Company's total cost associated with the Compliance Plan was
approximately $3.8 million, of which approximately $1.0 million was spent in
1998. Of the total cost, $2.2 million was capitalized. The costs of implementing
the integrated enterprise-wide information system are excluded as this system
implementation was undertaken primarily to improve business processes.

     As a result of the Company's plans and preparations, the Company did not
experience any significant malfunctions or errors in its Systems and Programs
when the date changed from 1999 to 2000. Based on operations since January 1,
2000, the Company does not expect any significant impact to its ongoing business
as a result of the Year 2000 issue. However, it is possible that the full impact
of the date change has not been fully recognized. The Company believes that any
such problems are likely to be minor and correctable. In addition, the Company
could still be negatively affected if its key suppliers, vendors and customers
are adversely affected by the Year 2000 or similar issues. The Company currently
is not aware of any significant Year 2000 or similar problems that have arisen
for its key suppliers, vendors and customers.

NEW ACCOUNTING STANDARD

     In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standard ("SFAS") No. 133, "Accounting for
Derivative Instruments and Hedging Activities," which establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts and for hedging activities. SFAS No. 133
requires that an entity recognize all derivatives as either assets or
liabilities in the statement of financial position and measure those instruments
at fair value. The accounting for changes in the fair value of a derivative
depends on the intended use of the derivative and the resulting designation.
SFAS No. 133, as amended, is effective for the Company
                                      A-18
<PAGE>   47

on January 1, 2001 and cannot be applied retroactively to financial statements
of prior periods. The Company enters into derivatives activities, on a limited
basis, as part of its programs to provide services for suppliers and customers.
The programs assist the Company in accessing refinery feedstocks at reasonable
costs and to hedge margins on sales to certain customers. Gains or losses on
hedging activities are recognized when the related physical transactions are
recognized as sales or purchases. Transactions, other than hedges, are marked to
market. The Company also engages in limited trading activities through the use
of derivatives. Management believes that any potential adverse impact from these
activities would not result in a material adverse effect on the Company's
financial results or financial position. The Company is evaluating the effects
that this statement will have on its financial condition, results of operations
and financial reporting and disclosures.

FORWARD-LOOKING STATEMENTS

     This Appendix A to the Proxy Statement for the 2000 Annual Meeting of
Stockholders contains certain statements that are "forward-looking" statements
within the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange Act of 1934, as amended. These forward-
looking statements include, among other things, discussions of estimated future
revenue enhancements and cost savings, the Company's business strategy and
expectations concerning the Company's market position, future operations,
margins, profitability, liquidity and capital resources, expenditures for
capital projects and attempts to reduce costs. Although the Company believes
that the assumptions upon which the forward-looking statements contained in this
Appendix A are based are reasonable, any of the assumptions could prove to be
inaccurate and, as a result, the forward-looking statements based on those
assumptions also could be incorrect. All phases of the operations of the Company
involve risks and uncertainties, many of which are outside the control of the
Company and any one of which, or a combination of which, could materially affect
the results of the Company's operations and whether the forward-looking
statements ultimately prove to be correct. Actual results and trends in the
future may differ materially depending on a variety of factors including, but
not limited to, the timing and extent of changes in commodity prices and
underlying demand and availability of crude oil, other refinery feedstocks and
refined products; changes in the cost or availability of third-party vessels,
pipelines and other means of transporting feedstocks and products; execution of
planned capital projects; results of management's evaluation of the Company's
cost structure, specifically the Alaska operations; adverse changes in the
credit ratings assigned to the Company's trade credit; state and federal
environmental, economic, safety and other policies and regulations, any changes
therein, and any legal or regulatory delays or other factors beyond the
Company's control; adverse rulings, judgments, or settlements in litigation or
other legal matters, including unexpected environmental remediation costs in
excess of any reserves; actions of customers and competitors; weather conditions
affecting the Company's operations or the areas in which the Company's products
are marketed; earthquakes or other natural disasters affecting operations;
political developments in foreign countries; and the conditions of the capital
markets and equity markets during the periods covered by the forward-looking
statements. All subsequent written and oral forward-looking statements
attributable to the Company or persons acting on its behalf are expressly
qualified in their entirety by the foregoing. The Company undertakes no
obligation to publicly release the result of any revisions to any such
forward-looking statements that may be made to reflect events or circumstances
after the date hereof or to reflect the occurrence of unanticipated events.

III. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     The Company utilizes various financial instruments and enters into
agreements which inherently have some degree of market risk. The primary sources
of market risk include fluctuations in commodity prices and interest rate
fluctuations.

PRICE FLUCTUATIONS

     The Company's refining and marketing earnings and cash flows from
operations are dependent upon the margin above fixed and variable expenses
(including the cost of crude oil feedstocks) at which the Company is able to
sell refined products. In recent years, the prices of crude oil and refined
products have fluctuated substantially. These prices depend on numerous factors
beyond the Company's control, including the demand

                                      A-19
<PAGE>   48

for crude oil, gasoline and other refined products, which in turn depend on,
among other factors, changes in the economy, the level of foreign and domestic
production of crude oil and refined products, worldwide political conditions,
the availability of imports of crude oil and refined products, the marketing of
alternative and competing fuels and the extent of government regulations. The
prices received by the Company for its refined products are also affected by
local factors such as local market conditions and the level of operations of
other refineries in the Company's markets.

     The prices at which the Company can sell its refined products are
influenced by the commodity price of crude oil. Generally, an increase or
decrease in the price of crude oil results in a corresponding increase or
decrease in the price of gasoline and other refined products; however, the
timing of the relative movement of the prices, as well as the overall reduction
in product prices, can reduce profit margins and could have a significant impact
on the Company's refining operations and the earnings and cash flows of the
Company as a whole. In addition, the Company maintains inventories of crude oil,
intermediate products and refined products, the value of each of which is
subject to rapid fluctuation in market prices. At December 31, 1999 and 1998,
the Company's inventories of refinery feedstocks and refined products totaled
8.6 million barrels and 11.1 million barrels, respectively. In addition, crude
oil supply contracts are generally contracts with market-responsive pricing
provisions. The Company purchases its refinery feedstock prior to selling the
refined products manufactured. Price level changes during the period between
purchasing feedstocks and selling the manufactured refined products from such
feedstocks could have a material effect on the Company's financial results. The
Company also purchases refined products manufactured by others. Price level
changes during the periods between purchasing and selling such products could
have a material effect on financial results.

     From time to time, the Company enters into derivatives activities, on a
limited basis, as part of its programs to provide services for suppliers and
customers. These programs assist the Company in accessing refinery feedstocks at
reasonable costs and to hedge margins on sales to certain customers. The Company
also engages in limited trading activities through the use of derivatives.
Management believes that any potential adverse impact from these activities
would not result in a material adverse effect on the Company's financial results
or financial position. At December 31, 1999, the Refining and Marketing segment
held the following derivative commodity instruments:

     - Crude oil futures contracts to purchase 25,000 barrels in February 2000
       at a weighted average price of $25.70 per barrel. The total amount of the
       contracts was $0.6 million and the fair value approximated the contract
       amount.
     - Contingent obligations to purchase 150,000 barrels of crude oil in
       February 2000 at a weighted average strike price of $27.17 per barrel
       under put options sold by the Company. The amount received for the
       options was approximately $0.2 million, and the market value of the
       options was an unrealized loss of $0.3 million at year-end 1999. None of
       these options, which expired in January 2000, were exercised.

     At December 31, 1999, the Marine Services segment held the following
derivative commodity instruments as part of its fuel acquisition program:

     - Heating oil futures contracts to purchase 3.4 million gallons from
       February through June 2000, at a weighted average price of $0.417 per
       gallon. The total contract amount was $1.4 million, and the fair value
       was $2.1 million at year-end 1999.

INTEREST RATE RISK

     Total debt at December 31, 1999 included $81 million of floating-rate debt
attributed to the Tranche B Term Loan and $337 million of fixed-rate debt.
Although the floating rate debt was repaid in March 2000, the Company will
continue to have exposure to short-term interest rate fluctuations based on
borrowings under its Revolver. See Note F of Notes to Consolidated Financial
Statements.

IV. FINANCIAL STATEMENTS

                          INDEPENDENT AUDITORS' REPORT

Board of Directors and Stockholders
Tesoro Petroleum Corporation

     We have audited the accompanying consolidated balance sheets of Tesoro
Petroleum Corporation and subsidiaries as of December 31, 1999 and 1998, and the
related statements of consolidated operations, stockholders' equity and cash
flows for each of the three years in the period ended December 31, 1999. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

     In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Tesoro Petroleum Corporation
and subsidiaries at December 31, 1999 and 1998, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1999 in conformity with accounting principles generally accepted in
the United States of America.

                          TESORO PETROLEUM CORPORATION

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE A -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Principles of Consolidation

     The accompanying Consolidated Financial Statements include the accounts of
Tesoro Petroleum Corporation and its subsidiaries (collectively, the "Company"
or "Tesoro"). All significant intercompany accounts and transactions have been
eliminated. Tesoro is an independent refiner and marketer of petroleum products
and provider of marine logistics services.

  Use of Estimates and Presentation

     Preparation of the Company's Consolidated Financial Statements in
conformity with generally accepted accounting principles requires the use of
management's best estimates and judgment that affect the reported amounts of
assets and liabilities and disclosures of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the year. Actual results could differ from those estimates.

     Unless otherwise stated, the Notes to Consolidated Financial Statements
exclude discontinued operations (see Note D). Certain reclassifications have
been made to information previously reported to conform to current presentation.
The Company did not have any material amounts which would be reported separately
from net earnings as "other comprehensive income."

  Cash and Cash Equivalents

     Cash equivalents consist of highly-liquid debt instruments such as
commercial paper and certificates of deposit purchased with an original maturity
date of three months or less. Cash equivalents are stated at cost, which
approximates market value. The Company's policy is to invest cash in
conservative, highly-rated instruments and to invest in various institutions to
limit the amount of credit exposure in any one institution. The Company monitors
the credit standing of these financial institutions.

  Financial Instruments

     The carrying amounts of financial instruments, including cash and cash
equivalents, receivables, accounts payable and certain accrued liabilities,
approximate fair value because of the short maturity of these instruments. The
carrying amounts of the Company's long-term debt and other obligations
approximate the Company's estimates of the fair value of such items.

  Inventories

     Inventories are stated at the lower of cost or market. The last-in,
first-out ("LIFO") method is used to determine the cost of the Company's
refining and marketing inventories of crude oil and refined products. The cost
of fuel at the Company's marine services terminals is determined on the
first-in, first-out ("FIFO") method. The carrying value of petroleum inventories
is sensitive to volatile market prices. Merchandise and materials and supplies
are valued at average cost, not in excess of market value. See Note I.

  Property, Plant and Equipment

     Additions to property, plant and equipment and major improvements and
modifications are capitalized at cost. Depreciation of property, plant and
equipment is generally computed on the straight-line method based upon the
estimated useful life of each asset. The weighted average lives range from 6 to
30 years for refining, marketing and pipeline assets, 14 to 15 years for service
equipment and marine fleets, and three to ten years for corporate and other
assets.

                          TESORO PETROLEUM CORPORATION

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     The Company follows the American Institute of Certified Public Accountants
Statement of Position No. 98-1, "Accounting for Costs of Computer Software
Developed or Obtained for Internal Use," to determine when to capitalize or
expense costs incurred to develop or obtain internal-use software. Under this
guidance, the Company expenses costs incurred in the preliminary project stage
and, thereafter, capitalizes costs incurred in developing or obtaining internal
use software. Certain costs, such as maintenance and training, are expensed as
incurred.

  Environmental Expenditures

     Environmental expenditures that extend the life or increase the capacity of
facilities, or expenditures that mitigate or prevent environmental contamination
that is yet to occur, are capitalized. Expenditures that relate to an existing
condition caused by past operations, and which do not contribute to current or
future revenue generation, are expensed. Liabilities are recorded when
environmental assessments and/or remedial efforts are probable. Cost estimates
are based on the expected timing and extent of remedial actions required by
applicable governing agencies, experience gained from similar sites on which
environmental assessments or remediation have been completed, and the amount of
the Company's anticipated liability considering the proportional liability and
financial abilities of other responsible parties. Generally, the timing of these
accruals coincides with the completion of a feasibility study or the Company's
commitment to a formal plan of action. Estimated liabilities are not discounted
to present value.

  Other Assets

     The cost over the fair value of net assets acquired (goodwill) is amortized
by the straight-line method over 28 years for refining and marketing assets and
20 years for marine services assets. At December 31, 1999 and 1998, goodwill
amounted to $67.5 million (net of accumulated amortization of approximately $4.9
million) and $55.6 million (net of accumulated amortization of approximately
$1.7 million), respectively.

     Refinery processing units are shut down periodically for major scheduled
maintenance (turnarounds). Certain catalysts are used in refinery process units
for periods exceeding one year. Also, ships, tugs and barges are drydocked for
periodic maintenance. Costs for turnarounds, catalyst and drydock are deferred
and amortized on a straight-line basis over the expected periods of benefit
generally ranging from 24 to 48 months.

     Debt issue costs are deferred and amortized using the effective interest
method over the estimated terms of each instrument.

  Revenue Recognition

     Revenues from product sales are recognized upon delivery to the customer.

  Income Taxes

     Deferred tax assets and liabilities are recognized for future income tax
consequences attributable to differences between financial statement carrying
amounts of assets and liabilities and their respective tax bases. Measurement of
deferred tax assets and liabilities is based on enacted tax rates expected to
apply to taxable income in the years in which those temporary differences are
expected to be recovered or settled. The effect on deferred tax assets and
liabilities of a change in tax rates is recognized in the period that includes
the enactment date.

  Stock-Based Compensation

     The Company accounts for stock-based compensation using the intrinsic value
method prescribed in Accounting Principles Board ("APB") No. 25, "Accounting for
Stock Issued to Employees," and related interpretations. Accordingly,
compensation cost for stock options is measured as the excess, if any, of the
                                      A-27

quoted market price of the Company's Common Stock at the date of grant over the
amount an employee must pay to acquire the stock, except for stock options
granted under the special incentive compensation which became fully vested in
May 1998 (see Note L).

  New Accounting Standard

     In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standard ("SFAS") No. 133, "Accounting for
Derivative Instruments and Hedging Activities," which establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts and for hedging activities. SFAS No. 133
requires that an entity recognize all derivatives as either assets or
liabilities in the statement of financial position and measure those instruments
at fair value. The accounting for changes in the fair value of a derivative
depends on the intended use of the derivative and the resulting designation.
SFAS No. 133, as amended, is effective for the Company on January 1, 2001 and
cannot be applied retroactively to financial statements of prior periods. The
Company enters into derivatives activities, on a limited basis, as part of its
programs to provide services for suppliers and customers. The programs assist
the Company in accessing refinery feedstocks at reasonable costs and to hedge
margins on sales to certain customers. Gains or losses on hedging activities are
recognized when the related physical transactions are recognized as sales or
purchases. Transactions, other than hedges, are marked to market. The Company
also engages in limited trading activities through the use of derivatives.
Management believes that any potential adverse impact from these activities
would not result in a material adverse effect on the Company's financial results
or financial position. The Company is evaluating the effects that this statement
will have on its financial condition, results of operations and financial
reporting and disclosures.

NOTE B -- EARNINGS PER SHARE

     Basic earnings per share are determined by dividing net earnings applicable
to Common Stock by the weighted average number of common shares outstanding
during the period. The Company's calculation of diluted earnings per share takes
into account the effect of potentially dilutive shares, principally stock
options, outstanding during the period. The assumed conversion of Preferred
Stock to 10.35 million shares of Common Stock produced anti-dilutive results in
1999 and 1998 and, in accordance with SFAS No. 128, was not included in the
dilutive calculation. Earnings (loss) per share calculations for the years ended
December 31, 1999, 1998 and 1997 are presented below (in millions except per
share amounts):

NOTE C -- OPERATING SEGMENTS

     The Company's revenues are derived from two operating segments: Refining
and Marketing and Marine Services. Management has identified these segments for
managing operations and investing activities in 1999.

  Refining and Marketing

     Refining and Marketing operates three petroleum refineries located in
Alaska, Hawaii and Washington which manufacture gasoline and gasoline
blendstocks, jet fuel, diesel fuel, heavy oils and other refined products. These
products, together with products purchased from third parties, are sold at
wholesale through terminal facilities and other locations in Alaska and Hawaii
and on the U.S. West Coast. In addition, Refining and Marketing markets
gasoline, other petroleum products and convenience store items through Company-
operated retail stations in Alaska and Hawaii. Refining and Marketing also
markets petroleum products through branded and unbranded stations located in
Alaska, Hawaii, Washington, Oregon, Idaho, Nevada and northern California and
will occasionally export products to other markets, principally in East Asia.
The Company at times resells previously purchased crude oil, sales of which
amounted to $16.6 million, $29.9 million and $44.4 million in 1999, 1998 and
1997, respectively. See Note E for information related to acquisitions in this
segment during 1998.

  Marine Services

     The Marine Services segment markets and distributes petroleum products,
water, drilling mud and other supplies and services primarily to the marine and
offshore exploration and production industries operating in the Gulf of Mexico.
This segment operated through terminals along the Texas and Louisiana Gulf Coast
and on the U.S. West Coast in 1999. See Note E for information related to an
acquisition in this segment during 1999.

  Other

     Segment operating profit includes those revenues and expenses that are
directly attributable to management of the respective segment. For the years
presented, revenues were generated from sales to external customers, and
intersegment revenues were not significant. Income taxes, interest and financing
costs, interest income and corporate general and administrative expenses are not
included in determining segment operating profit. Corporate and unallocated
costs in 1998 included $19.1 million for special incentive compensation, of
which $7.1 million related to the operating segments (see Note L).

     EBITDA represents earnings before extraordinary items, interest and
financing costs, income taxes, and depreciation, depletion and amortization.
While not purporting to reflect any measure of the Company's operations or cash
flows, EBITDA is presented for additional analysis. Operating segment EBITDA is
equal to segment operating profit before depreciation and amortization related
to each segment.

     Identifiable assets are those assets utilized by the segment. Corporate
assets are principally cash and other assets that are not directly associated
with the operations of a business segment. For the years prior to 1999,

NOTE D -- DISCONTINUED OPERATIONS

     On December 17, 1999, the Company completed the sale of its domestic
exploration and production business to EEX Corporation effective July 1, 1999.
The business sold included Tesoro's four core areas of domestic exploration and
production operations located in Texas and Louisiana and all of Tesoro's acreage
in those areas, together with Tesoro's interests in other miscellaneous
exploration and production properties and gas transportation facilities. The
cash sale prices in the purchase agreements totaled $222 million, which were
adjusted on a preliminary basis for revenues, expenses, capital expenditures,
working capital changes and certain other items after the effective date to
approximately $214.8 million in cash received at closing. Under the terms of the
purchase agreements, these transactions were structured as sales of stock in
subsidiary corporations and membership interests in subsidiary limited liability
companies. The consideration received, which was determined through a
competitive bidding process and negotiations with EEX Corporation, is subject to
post-closing adjustments for operations between July 1, 1999, the effective
date, and December 17, 1999, the closing date, on or before April 15, 2000.

     On December 29, 1999, the Company completed the sale of its Bolivian
exploration and production operations to BG International, Ltd., a subsidiary of
BG plc, effective July 1, 1999. The business sold included five shared-risk
contracts with an agency of the Bolivian government to explore for and produce
hydrocarbons on more than one million gross acres in two producing blocks and
three non-producing blocks. The cash sale price in the purchase agreement
totaled $100 million, which was adjusted on a preliminary basis for revenues,
expenses, capital expenditures, working capital changes and certain other items
after the effective date to approximately $100.8 million in cash received at
closing. Under the terms of the purchase agreement, this transaction was
structured as a sale of stock in a subsidiary corporation. The consideration
received, which was determined through a competitive bidding process and
negotiations with BG International, Ltd., is subject to post-closing adjustments
for operations between July 1, 1999, the effective date, and December 29, 1999,
the closing date, on or before May 27, 2000.

     The total cash proceeds of $307.5 million, after transaction costs of $8.1
million, were used in December 1999 to reduce term loans outstanding under the
Company's senior credit facility by $97.4 million and prepay certain
liabilities. The remaining cash proceeds, which were held by the Company for
general corporate purposes at December 31, 1999, have been substantially used
subsequent to year-end to repay additional debt (see Note F).

     The Company's consolidated financial statements for periods prior to the
sales have been restated to report the net assets, results of operations and
cash flows of the exploration and production business as

NOTE E -- ACQUISITIONS AND EXPANSIONS

  Acquisitions of Hawaii Refinery and Washington Refinery

     On May 29, 1998, the Company acquired (the "Hawaii Acquisition") all of the
outstanding capital stock of two affiliates of The Broken Hill Proprietary
Company Limited ("BHP"). The Hawaii Acquisition included a 95,000-barrel per day
refinery (the "Hawaii Refinery") and 32 retail gasoline stations in Hawaii.
Tesoro and a BHP affiliate entered into a crude supply agreement pursuant to
which the BHP affiliate will assist Tesoro in acquiring crude oil feedstocks
sourced outside of North America and arrange for the transportation of such
crude oil to the Hawaii Refinery through May 2000. Tesoro paid $252.2 million in
cash for the Hawaii Acquisition, including $77.2 million for working capital. In
addition, Tesoro issued an unsecured, non-interest bearing, promissory note
("BHP Note") for $50 million. The estimated present value of the BHP Note was
recorded as part of the purchase price.

     On August 10, 1998, the Company acquired (the "Washington Acquisition" and
together with the Hawaii Acquisition, the "Acquisitions") all of the outstanding
stock of an affiliate of Shell Oil Company

("Shell"). The Washington Acquisition included a 108,000-barrel per day refinery
(the "Washington Refinery") in Anacortes, Washington and related assets. The
total cash purchase price for the Washington Acquisition was $280.1 million,
including $43.1 million for working capital.

     The Acquisitions were accounted for as purchases whereby the purchase
prices were allocated to the assets acquired and liabilities assumed based upon
their respective fair market values at the dates of acquisition. Under purchase
accounting, financial results of the Acquisitions have been included in Tesoro's
consolidated financial statements since the dates of acquisition.

     See Note F for information related to financing the Acquisitions and Note M
for related environmental matters.

  Other Refining and Marketing Expansions

     In addition to normal capital improvements in 1999, the Company completed
the installation of a distillate treater at its Washington Refinery in December
which enables the refinery to increase its production of low-sulfur diesel fuel
and jet fuel. The distillate treater installation, together with licensing fees
and supporting infrastructure, cost approximately $13 million.

     In August 1999, the Company purchased a refined products terminal in
Anchorage, Alaska for approximately $8 million in cash. This terminal, which is
near the Company's existing terminal in Anchorage, provides the Company with
additional storage and purchasing flexibility.

     In October 1997, the Company completed an expansion of its Alaska refinery
hydrocracker unit which enabled the Company to increase its jet fuel production.
The expansion, together with the addition of a new, high-yield jet fuel
hydrocracker catalyst, was completed at a cost of approximately $19 million.

  Marine Services

     In June 1999, the Company purchased the U.S. West Coast marine fuels
operations of BP Marine, a division of BP Amoco PLC. The purchase, which
included inventory and leased facilities at Port Angeles and Seattle,
Washington, and Portland, Oregon, expanded the Company's presence on the West
Coast.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     At December 31, 1999, aggregate maturities of outstanding long-term debt
and other obligations, including the BHP Note and Tranche B Term Loan, for each
of the five years following December 31, 1999 were as follows: 2000 -- $27.4
million; 2001 -- $4.7 million; 2002 -- $4.7 million; 2003 -- $2.1 million; and
2004 -- $78.3 million. The Company prepaid the $24.0 million BHP Note on March
1, 2000 and the remaining $80.9 million balance of the Tranche B Term Loan on
March 13, 2000. After giving effect to these prepayments, aggregate maturities
of long-term debt thereafter will be as follows: 2000 -- $2.4 million; 2001
 -- $3.7 million; 2002 -- $3.7 million; 2003 -- $1.1 million; and 2004 -- $1.4
million.

  Credit Facility

     On July 2, 1998, and in connection with the Notes Offering (defined below)
and the Washington Acquisition, the Company entered into a senior credit
facility ("Senior Credit Facility") in the amount of $500 million. The Senior
Credit Facility was comprised of term loan facilities aggregating $200 million
(the "Tranche A Term Loans" and the "Tranche B Term Loan"), and a $300 million
revolving credit and letter of credit facility ("Revolver"). In January 1999,
the final $50 million under the Tranche A Term Loans was borrowed and used to
reduce borrowings under the Revolver. In April 1999, the Company reduced
commitments under the Revolver from $300 million to $175 million, reducing
commitment fees. The Company used a portion of the proceeds from the sale of its
exploration and production operations (see Note D) to prepay all of the
remaining $79.8 million in Tranche A Term Loans and reduce the Tranche B Term
Loan by $17.6 million in December 1999. At year-end, the Company had outstanding
borrowings of $80.9 million under the Tranche B Term Loan and no borrowings
under the Revolver. Subsequent to year-end 1999, the Company concluded that
available cash was not required for other corporate purposes, and on March 13,
2000, the Company prepaid the remaining $80.9 million balance on the Tranche B
Term Loan. Based on current needs, the remaining capacity of $175 million under
the Revolver, together with internally-generated cash flows and existing cash,
is expected to be sufficient to fund capital expenditures and working capital
requirements. Outstanding letters of credit totaled $3.4 million and unused
availability under the Senior Credit Facility was approximately $171.6 million
at December 31, 1999.

     The Revolver, which terminates on July 2, 2001, bears interest, at the
Company's election, at either the Base Rate (as defined in the Senior Credit
Facility) plus a margin ranging from 0.00% to 0.625% or the Eurodollar Rate (as
defined in the Senior Credit Facility) plus a margin ranging from 1.125% to
2.125%. At December 31, 1999, the interest rate on borrowings under the Senior
Credit Facility was 9.0%.

     The Senior Credit Facility requires the Company to maintain specified
levels of consolidated leverage and interest coverage and contains other
covenants and restrictions customary in credit arrangements of this kind. The
Company was in compliance with these covenants at December 31, 1999. The terms
of the Senior Credit Facility allow for payment of cash dividends on the
Company's Common Stock not to exceed an aggregate of $10 million in any year and
also allow for payment of required dividends on its 7.25% Mandatorily
Convertible Preferred Stock. The Senior Credit Facility is guaranteed by
substantially all of the Company's active direct and indirect subsidiaries
("Guarantors") and is secured by substantially all of the domestic assets of the
Company and each of the Guarantors.

     In conjunction with closing the Hawaii Acquisition (see Note E) in May
1998, Tesoro refinanced substantially all of its then-existing indebtedness and
recorded an extraordinary loss on early extinguishment of debt of $7.0 million
pretax ($4.4 million aftertax, or $0.15 per basic and diluted share) for the
refinancing during the second quarter of 1998.

  Senior Subordinated Notes

     On July 2, 1998, concurrently with the syndication of the Senior Credit
Facility, the Company issued $300 million aggregate principal amount of 9%
senior subordinated notes due 2008 through a private offering ("Notes
Offering"). Each $1,000 principal amount of its unregistered and outstanding
senior subordinated

notes due 2008 was exchanged for $1,000 principal amount of the Company's
registered 9% Senior Subordinated Notes due 2008, Series B ("Senior Subordinated
Notes") in September 1998. The Senior Subordinated Notes have a ten-year
maturity without sinking fund requirements and are subject to optional
redemption by the Company after five years at declining premiums. The indenture
("Indenture") for the Senior Subordinated Notes contains covenants and
restrictions which are customary for notes of this nature. The restrictions
under the Indenture are less restrictive than those in the Senior Credit
Facility. To the extent the Company's fixed charge coverage ratio, as defined in
the Indenture, allows for the incurrence of additional indebtedness, the Company
will be allowed to pay cash dividends on Common Stock and repurchase shares of
Common Stock. The effective interest rate on the Senior Subordinated Notes is
9.16%, after giving effect to the discount at the date of issue.

  Common Stock and Preferred Stock

     In May 1998, the Company filed a universal shelf registration statement
("Shelf Registration") for $600 million of debt or equity securities for
acquisitions or general corporate purposes. The Company offered Premium Income
Equity Securities ("PIES") and Common Stock (collectively, the "Equity
Offerings" and together with the Notes Offering, the "Offerings") from the Shelf
Registration to provide partial funding for the Acquisitions discussed in Note
E. In July 1998, the Company issued 10,350,000 PIES, representing fractional
interests in the Company's 7.25% Mandatorily Convertible Preferred Stock
("Preferred Stock"), with gross proceeds of approximately $165 million, and
5,750,000 shares of Common Stock, with gross proceeds of $91.6 million. Holders
of PIES are entitled to receive a cash dividend. The PIES will automatically
convert into shares of Common Stock on July 1, 2001, at a rate based upon a
formula dependent upon the market price of Common Stock. Before July 1, 2001,
each PIES is convertible, at the option of the holder thereof, into 0.8455
shares of Common Stock, subject to adjustment in certain events, such as Common
Stock splits and stock dividends.

     In February 2000, the Company's Board of Directors authorized the
repurchase of up to 3 million shares of Tesoro Common Stock, which represents
approximately 9% of the 32.4 million shares then outstanding. Under the program,
the Company will repurchase Tesoro Common Stock from time to time in the open
market and through privately negotiated transactions. Purchases will depend on
price, market conditions and other factors and will be made primarily from
internally-generated cash flow. The stock may be used to meet employee benefit
plan requirements and other corporate purposes. Under a similar program, in 1997
the Company repurchased 236,800 shares of Common Stock for approximately $3.7
million.

     For information relating to stock-based compensation and Common Stock
reserved for exercise of options and conversion of Preferred Stock, see Note L.

  BHP Note

     In connection with the Hawaii Acquisition (Note E), Tesoro issued an
unsecured, non-interest bearing, promissory note ("BHP Note") for the purchase
in the amount of $50 million, payable in five equal annual installments of $10
million each, beginning in 2009. The BHP Note provided for early payments based
on earnings from the Hawaii Acquisition, as specified in the BHP Note. Based on
1998 earnings from the Hawaii Acquisition, an early principal payment of $3.6
million was made on the BHP Note in 1999. The present value of the BHP Note,
discounted at 10% and including the effect of the early principal payment, was
recorded as part of the purchase price of the Hawaii Acquisition. The carrying
value of the note, approximately $24 million at December 31, 1999, approximated
its estimated present value and was paid to BHP on March 1, 2000, in complete
satisfaction of the BHP Note.

  Department of Energy

     A Consent Order entered into by the Company with the Department of Energy
("DOE") in 1989 settled all issues relating to the Company's compliance with
federal petroleum price and allocation regulations from 1973 through decontrol
in 1981. At December 31, 1999, the Company's remaining obligation is to pay the
DOE $6.6 million, plus interest at 6%, over the next three years.

  Capital Leases

     Capital leases are primarily for tugs and barges used in transportation of
petroleum products within Hawaii. At December 31, 1999 and 1998, the cost of
capital leases included in fixed assets was $10.4 million gross (accumulated
amortization of $2.0 million) and $9.3 million gross (accumulated amortization
of $0.9 million), respectively. Capital lease obligations included in long-term
debt totaled $8.7 million and $9.8 million at December 31, 1999 and 1998,

NOTE H -- RECEIVABLES

     Concentrations of credit risk with respect to accounts receivable are
limited, due to the large number of customers comprising the Company's customer
base and their dispersion across the Company's industry segments and geographic
areas of operations. The Company performs ongoing credit evaluations of its
customers' financial condition and in certain circumstances requires letters of
credit or other collateral arrangements. The Company's allowance for doubtful
accounts is reflected as a reduction of receivables in the Consolidated Balance
Sheets and amounted to $1.7 million and $1.6 million at December 31, 1999 and
1998, respectively.

NOTE I -- INVENTORIES

     Components of inventories at December 31, 1999 and 1998 were as follows (in

</TABLE>

     At December 31, 1999, inventories valued using LIFO were lower than
replacement cost by approximately $89 million. During 1999, certain inventory
quantities were reduced, resulting in a liquidation of applicable LIFO inventory
quantities carried at lower costs prevailing in previous years. This LIFO
liquidation resulted in a decrease in cost of sales of $8.4 million and an
increase in earnings from continuing operations of approximately $5.3 million
aftertax ($0.16 per share) during 1999.

NOTE K -- BENEFIT PLANS

  Pension Benefits and Other Postretirement Benefits

     The Company sponsors defined benefit pension plans, including an employee
retirement plan, executive security plans and a non-employee director retirement
plan.

     For all eligible employees, the Company provides a qualified
noncontributory retirement plan ("Retirement Plan"). Plan benefits are based on
years of service and compensation. The Company's funding policy is to make
contributions at a minimum in accordance with the requirements of applicable
laws and regulations, but no more than the amount deductible for income tax
purposes. Retirement plan assets are primarily comprised of common stock and
bond funds.

     The Company's executive security plans ("ESP Plans") provide executive
officers and other key personnel with supplemental death or retirement plans.
Such benefits are provided by two nonqualified, noncontributory plans and are
based on years of service and compensation. The Company makes contributions to
one plan based upon estimated requirements. Assets of the funded plan consist of
a group annuity contract.

     The Company had previously established an unfunded non-employee director
retirement plan ("Director Retirement Plan") which provided eligible directors
retirement payments upon meeting certain age or other requirements. However, in
March 1997, the Board of Directors elected to freeze the Director Retirement
Plan and transfer accrued benefits of current directors to the Tesoro Petroleum
Corporation Board of Directors Phantom Stock Plan (see Note L). After the
amendment and transfer, only those retired directors or beneficiaries who had
begun to receive benefits remained participants in the Director Retirement Plan.

     SFAS No. 132, "Employers' Disclosures about Pensions and Other
Postretirement Benefits," requires the Company to disclose the aggregate
projected benefit obligations, accumulated benefit obligations and fair value of
plan assets for pension plans with accumulated benefit obligations in excess of
plan assets. At December 31, 1999, the projected benefit obligation and
accumulated benefit obligation aggregated for the unfunded ESP plan and the
Director Retirement Plan were $2.4 million and $1.5 million, respectively. At
December 31, 1998, the projected benefit obligation and accumulated benefit
obligation aggregated for these two plans were $3.7 million and $1.7 million,
respectively. In addition, at December 31, 1998, the Retirement Plan's
accumulated benefit obligation exceeded plan assets. The Retirement Plan's
projected benefit obligation, accumulated benefit obligation and fair value of
plan assets were $82.0 million, $64.5 million and $59.1 million, respectively,
at December 31, 1998. The assets of the Retirement Plan exceeded its accumulated
benefit obligation at December 31, 1999.

     The Company provides health care and life insurance benefits to retirees
who were participating in the Company's group insurance program at retirement.
Health care is provided to qualified dependents of participating retirees. These
benefits are provided through unfunded, defined benefit plans or through
contracts with area health-providers on a premium basis. The health care plans
are contributory, with retiree contributions adjusted periodically, and contain
other cost-sharing features such as deductibles and coinsurance. The life
insurance plan is noncontributory. The Company funds its share of the cost of
postretirement health care and life insurance benefits on a pay-as-you go basis.

     Assumed health care cost trend rates have a significant effect on the
amounts reported for the health care and life insurance plans. A
one-percentage-point change in assumed health care cost trend rates could have

  Thrift Plan

     The Company sponsors an employee thrift plan ("Thrift Plan") which provides
for contributions, subject to certain limitations, by eligible employees into
designated investment funds with a matching contribution by the Company.
Employees may elect tax deferred treatment in accordance with the provisions of
Section 401(k) of the Internal Revenue Code. Effective September 1, 1998, the
Thrift Plan was amended to change the Company's 100% matching contribution, from
a maximum of 4% to 6% of the employee's eligible contribution, with at least 50%
of the Company's matching contribution invested in Common Stock of the Company.
In addition, the maximum employee contribution changed from 10% to 15%. The
Company's contributions amounted to $6.8 million, $1.7 million and $1.2 million
during 1999, 1998 and 1997, respectively.

NOTE L -- STOCK-BASED COMPENSATION

  Incentive Stock Plans

     The Company has three employee incentive stock plans, the Key Employee
Stock Option Plan ("1999 Plan"), the Amended and Restated Executive Long-Term
Incentive Plan ("1993 Plan") and Amended Incentive Stock Plan of 1982 ("1982
Plan"). In addition, the Company has the 1995 Non-Employee Director Stock Option
Plan ("1995 Plan").

     In November 1999, the Company's Board of Directors approved the 1999 Plan
which provides for the granting of stock options to eligible persons employed by
the Company who are not executive officers of the Company. Under the 1999 Plan,
the total number of stock options which may be granted is 200,000 shares, of
which 98,000 shares were granted in 1999. Stock options may be granted at not
less than the fair market value on the date the options are granted and
generally become exercisable after one year in 25% increments. The options
expire after ten years from the date of grant. The Board of Directors may amend,
terminate or suspend

the 1999 Plan at any time. At December 31, 1999, the Company had 102,000 shares
available for future grants under the 1999 Plan.

     Under the 1993 Plan, shares of Common Stock may be granted in a variety of
forms, including restricted stock, incentive stock options, nonqualified stock
options, stock appreciation rights and performance share and performance unit
awards. In 1998, the aggregate number of shares of Common Stock which can be
granted under the 1993 Plan was increased from 2,650,000 to 4,250,000. Stock
options may be granted at exercise prices not less than the fair market value on
the date the options are granted. The options granted generally become
exercisable after one year in 20%, 25% or 33% increments per year and expire ten
years from the date of grant. The 1993 Plan will expire, unless earlier
terminated, as to the issuance of awards in the year 2003. At December 31, 1999,
the Company had 153,553 shares available for future grants under the 1993 Plan.

     The 1982 Plan expired in 1994 as to issuance of stock appreciation rights,
stock options and stock awards; however, grants made before the expiration date,
that have not been fully exercised, remain outstanding pursuant to their terms.

     The 1995 Plan provides for the grant of up to an aggregate of 150,000
nonqualified stock options to eligible non-employee directors of the Company.
These automatic, non-discretionary stock options are granted at an exercise
price equal to the fair market value per share of the Company's Common Stock as
of the date of grant. The term of each option is ten years, and an option first
becomes exercisable six months after the date of grant. The 1995 Plan will

  Phantom Stock Agreement and Phantom Stock Plan

     In 1997, the Compensation Committee of the Board of Directors granted
175,000 phantom stock options to an executive officer of the Company at 100% of
the fair market value of the Company's Common Stock on the grant date, or
$16.9844 per share. These phantom stock options vest in 15% increments in each
of the first three years and the remaining 55% increment vests in the fourth
year. At December 31, 1999, 52,500 of these phantom stock options were
exercisable. Upon exercise, the executive officer would be entitled to receive
in cash the difference between the fair market value of the Common Stock on the
date of the phantom stock option grant and the fair market value of Common Stock
on the date of exercise. At the discretion of the Compensation Committee, these
phantom stock options may be converted to traditional stock options under the
1993 Plan.

     To more closely align director compensation with shareholders' interests,
in March 1997, the lump-sum accrued benefit of each of the current non-employee
directors was transferred from the Director Retirement Plan (see Note K) into an
account ("Account") in the Company's Board of Directors Deferred Phantom Stock
Plan ("Phantom Stock Plan"). Under the Phantom Stock Plan, a yearly credit of
$7,250 (prorated to $6,042 for 1997) is made to the Account of each director in
units, based upon the closing market price of the Company's Common Stock on the
date of credit. In addition, a director may elect to have the value of his cash
retainer fee deposited quarterly into the Account in units. The value of each
Account balance, which is a function of the amount, if any, by which the market
value of the Company's Common stock changes, is payable in cash at termination,
if vested, with three years of service, or at retirement, death or disability.
In 1999 and 1997, the Company recorded expense of approximately $44,000 and
$127,000, respectively, related to phantom stock. In 1998, the Company credited
expense for approximately $110,000 related to phantom stock due to the net
depreciation in the market price of the Company's Common Stock.

  Incentive Compensation

     In October 1998, the Company's Board of Directors unanimously approved the
1998 Performance Incentive Compensation Plan ("1998 Performance Plan"), which is
intended to advance the best interests of the Company and its stockholders by
directly targeting Company performance to align with the ninetieth percentile
historical stock-price growth rate for the Company's peer group. In addition,
the 1998 Performance Plan will provide the Company's employees with additional
compensation, contingent upon achievement of the targeted objectives, thereby
encouraging them to continue in the employ of the Company. Under the 1998
Performance Plan, targeted objectives are comprised of the fair market value of
the Company's Common Stock equaling or exceeding an average of $35 per share
("First Performance Target") and $45 per share ("Second Performance Target") on
any 20 consecutive trading days during a period commencing on October 1, 1998
and ending on the earlier of September 30, 2002, or the date on which the Second
Performance Target is achieved ("Performance Period"). The 1998 Performance Plan
has several tiers of

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

awards, with the award generally determined by job level. Most eligible
employees have contingent cash bonus opportunities of 25% of their annual "basic
compensation" (as defined in the 1998 Performance Plan) and three executive
officers have contingent awards totaling 655,000 shares of phantom stock which
will be payable solely in cash. Upon achievement of the First Performance
Target, one-fourth of the contingent award will be earned, with payout deferred
until the end of the Performance Period. The remaining 75% will be earned only
upon achievement of the Second Performance Target, with payout occurring 30 days
thereafter. Employees will need to have at least one year of regular, full-time
service at the time the Performance Period ends in order to be eligible for a
payment. No costs will be recorded until the First Performance Target is
reached. The Company estimates that it will incur costs of approximately 2% of
the total aggregate increase in shareholder value if the First Performance
Target is reached and will incur an additional 4% charge if the Second
Performance Target is reached.

     In May 1998, under a previous special incentive compensation strategy, the
Company incurred a pretax charge of approximately $19.1 million, of which $7.1
million related to operating segments, when the market price of the Company's
Common Stock achieved a specific performance target. Of this charge,
approximately $10 million related to noncash vesting of restricted stock awards
and stock options and $9 million related to cash bonuses.

  Pro Forma Information

     The Company applies APB No. 25 and related interpretations in accounting
for its stock-based compensation. Had compensation cost been determined based on
the fair value at the grant dates for awards in accordance with SFAS No. 123,
"Accounting for Stock-Based Compensation," the Company's pro forma results in
1999, 1998 and 1997 would have been net earnings of $71.4 million ($1.83 per
basic share, $1.81 per diluted share), a net loss of approximately $22.3 million
($0.96 per basic and diluted share) and net earnings of $28.5 million ($1.08 per
basic share, $1.06 per diluted share), respectively. The fair value of each
option grant was estimated on the date of grant using the Black-Scholes
option-pricing model with the following weighted-average assumptions: expected
volatility of 48%, 49% and 32%; risk free interest rates of 6.1%, 4.7% and 6.7%;
expected lives of seven years; and no dividend yields for 1999, 1998 and 1997,
respectively. The estimated average fair value per share of options granted
during 1999, 1998 and 1997 were $7.48, $7.85 and $5.96, respectively. The fair
value of phantom stock awards in 1998 was $0.82 per share.

  Shares Reserved

     Shares of unissued Common Stock reserved for the employee incentive stock
plans and non-employee director plan totaled 4,079,952 at December 31, 1999. In
addition, at December 31, 1999, 8,750,925 shares of unissued Common Stock were
reserved for the conversion of Preferred Stock (see Note F).

NOTE M -- COMMITMENTS AND CONTINGENCIES

  Operating Leases

     The Company has various noncancellable operating leases related to
buildings, equipment, property and other facilities. These long-term leases have
remaining primary terms generally up to ten years, with terms of certain
rights-of-way extending up to 31 years, and generally contain multiple renewal
options. Future

excluding marine charters, were as follows (in millions):

     In addition to the long-term lease commitments above, the Company charters
two double-bottomed vessels, the Chesapeake Trader and the Potomac Trader, to
transport crude oil and refined products. The Chesapeake Trader and the Potomac
Trader are chartered under five-year agreements expiring in May 2000 and
September 2000, respectively. At December 31, 1999, future minimum lease
payments remaining for these two vessels totaled approximately $17 million
through their term expirations in 2000. The Company also enters into various
month-to-month and other short-term rentals of vessels to transport refined
products from the Company's refineries to markets. Total marine charter expense
was $37 million in 1999 and $34 million in each of 1998 and 1997. During 1999,
the Company received $4.5 million in revenues from the sub-charter of vessels to
third parties.

     In 1999, the Company entered into a charter for a double-hull tanker to be
used for transporting crude oil and refined products which will replace the
Chesapeake Trader. Under the terms of the new charter, Tesoro will receive one
of the new Lightship Class tankers. The new charter, which has a three-year
primary term beginning in May 2000 and two one-year options, will require
minimum annual lease payments of approximately $10 million, saving the Company
approximately $6 million annually. At December 31, 1999, total future minimum
annual payments (which include operating costs) for long-term marine charters
totaled $23 million in 2000, $10 million in 2001, $10 million in 2002 and $3
million in 2003, reflecting the replacement of the Chesapeake Trader in May 2000
and the term expiration of the Potomac Trader in September 2000. The Company
also leases tugs and barges for its Hawaii operations under capital leases (see
Note F) whereby the Company pays operating costs, such as personnel, repairs,
maintenance and drydocking costs, estimated to total $8 million in 2000.

     Total rental expense for short-term and long-term leases, excluding marine
charters, amounted to approximately $27 million, $20 million and $11 million for
1999, 1998 and 1997, respectively.

     In January 2000, the Company entered into an agreement with Wal-Mart
Stores, Inc., in which Wal-Mart has agreed to offer no less than 40 sites at
Wal-Mart stores in eleven states in the western U.S. at which the Company can
build and operate retail gasoline stations. Under the agreement, each site will
be subject to a lease with a ten-year primary term and an option, exercisable at
the Company's discretion, to extend a site for two additional terms of five
years each. On March 2, 2000, the Company accepted the first 14 sites offered by
Wal-Mart. The minimum annual lease commitments for these 14 sites is
approximately $0.3 million, and the total commitment is approximately $3 million
over the initial ten-year term.

  Other Commitments

     Under an agreement with the State of Alaska reached in June 1998, the State
released the Company from all payment obligations and all mortgages, liens and
security interests in connection with a 1993 agreement settling a contract
dispute with the State. The Company is obligated to pay the State of Alaska a
throughput charge of $0.32 per barrel in 2000 and $0.33 per barrel in 2001 with
respect to barrels of feedstock

processed at the Alaska refinery which exceed 50,000 barrels per day on a
monthly basis, subject to available credits (as defined in the agreement). No
payments were required in 1999.

  Environmental and Other

     The Company is a party to various litigation and contingent loss
situations, including environmental matters, arising in the ordinary course of
business. The Company has made accruals in accordance with SFAS No. 5,
"Accounting for Contingencies," in order to provide for these matters. The
ultimate effects of these matters cannot be predicted with certainty, and
related accruals are based on management's best estimates, subject to future
developments. Although the resolution of certain of these matters could have a
material adverse impact on interim or annual results of operations, the Company
believes that the outcome of these matters will not result in a material adverse
effect on its liquidity or consolidated financial position.

     The Company is subject to extensive federal, state and local environmental
laws and regulations. These laws, which change frequently, regulate the
discharge of materials into the environment and may require the Company to
remove or mitigate the environmental effects of the disposal or release of
petroleum or chemical substances at various sites or install additional controls
or other modifications or changes in use for certain emission sources.

     The Company is currently involved with the Environmental Protection Agency
("EPA") regarding a waste disposal site near Abbeville, Louisiana. The Company
has been named a potentially responsible party ("PRP") under the Federal
Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"
or "Superfund") at this location. Although the Superfund law might impose joint
and several liability upon each party at the site, the extent of the Company's
allocated financial contribution for cleanup is expected to be de minimis based
upon the number of companies, volumes of waste involved and total estimated
costs to close the site. The Company believes, based on these considerations and
discussions with the EPA, that its liability at the Abbeville site will not
exceed $25,000.

     In connection with the Hawaii Acquisition discussed in Note E, affiliates
of BHP and the Company executed a separate environmental agreement, whereby the
BHP affiliates indemnified the Company for environmental costs arising out of
conditions which existed at or prior to closing. This indemnification, which is
in effect until 2008, is subject to a maximum limit of $9.5 million ($8.2
million remaining as of December 31, 1999). Under the environmental agreement,
the first $5.0 million of these liabilities will be the responsibility of the
BHP affiliates and the next $6.0 million will be shared on the basis of 75% by
the BHP affiliates and 25% by the Company. Certain environmental claims arising
out of prior operations will not be subject to the $9.5 million limit or the
ten-year time limit. The indemnity obligation of the BHP affiliates are
guaranteed by BHP.

     Under the agreement related to the Washington Acquisition discussed in Note
E, an affiliate of Shell generally agreed to indemnify the Company for
environmental liabilities at the Washington Refinery arising out of conditions
which existed at or prior to the closing date and identified by the Company
prior to August 1, 2001. The Company is responsible for environmental costs up
to the first $0.5 million each year, after which the Shell affiliate will be
responsible for annual environmental costs up to $1.0 million. Annual costs
greater than $1.0 million will be shared equally between the Company and the
Shell affiliate, subject to an aggregate maximum of $5.0 million and a ten-year
term. The indemnity obligation of Shell's affiliate is guaranteed by Shell.

     The Company is also involved in remedial responses and has incurred cleanup
expenditures associated with environmental matters at a number of sites,
including certain of its own properties. At December 31, 1999, the Company's
accruals for environmental expenses totaled $13.6 million. Based on currently
available information, including the participation of other parties or former
owners in remediation actions, the Company believes these accruals are adequate.

     To comply with environmental laws and regulations, the Company anticipates
that it will make capital improvements of approximately $8 million in 2000 and
$10 million in 2001. The Company is currently evaluating certain proposed
revisions to the Clean Air Act regulations which would require a reduction in
the sulfur content in gasoline fuel manufactured at its refineries. The Company
expects that it will make capital improvements to certain equipment at its
Washington Refinery to meet the revised gasoline standard. Additional proposed
changes to the Clean Air Act regulations may include new emission controls at
certain processing units at each of the Company's refineries. The Company
anticipates that the revisions to the Clean Air Act will become effective over
the next three to five years and that, based on known current technology, it
could spend approximately $25 million to $30 million to comply with these
proposed revisions.

     Conditions that require additional expenditures may exist for various
Company sites, including, but not limited to, the Company's refineries, retail
gasoline stations (operating and closed locations) and petroleum product
terminals, and for compliance with the Clean Air Act and other state and federal
regulations. The amount of such future expenditures cannot currently be
determined by the Company.

     On October 1, 1998, the Attorney General for the State of Hawaii filed a
lawsuit in the U.S. District Court for the District of Hawaii ("Court") against
thirteen oil companies, including Tesoro Petroleum Corporation and Tesoro Hawaii
Corporation, alleging anti-competitive marketing practices in violation of
federal and state anti-trust laws, and seeking injunctive relief and
compensatory and treble damages and civil penalties against all defendants in an
amount in excess of $500 million. On March 25, 1999, the Attorney General filed
an amended complaint with the U.S. District Court seeking damages against all
defendants for such alleged anti-competitive marketing practices in an amount in
excess of $1.5 billion. On January 28, 2000, the U.S. District Court for the
District of Hawaii approved a Settlement Agreement and Mutual Release
("Settlement Agreement") reached between Tesoro Hawaii Corporation, the Company,
BHP Hawaii Inc. and BHP Petroleum Americas Refining Inc. (the "Settling
Defendants") and the State of Hawaii which dismissed the Settling Defendants
from the lawsuit. Pursuant to the Settlement Agreement, the Company and Tesoro
Hawaii Corporation, without admitting any liability for claims alleged in the
lawsuit, paid $3 million (which was provided for in the third quarter of 1999)
on March 1, 2000 to the Court in complete settlement of the lawsuit.
